ICAHN 767 Fifth Avenue, 47th Floor New York, New York 10153 March 29, 2011 VIA FEDERAL EXPRESS AND EMAIL ----------------------------- Board of Directors Mentor Graphics Corporation 8005 S.W. Boeckman Road Wilsonville, OR 97070-7777 Gentlemen and Ladies: To preempt your proposed dilutive convertible debt offering, which may act to derail an acquisition proposal, we would be willing to lend the Company $220 million on a senior unsecured basis, at a rate of 6.25%, for a period of two and a half years. This note will not be convertible into common shares and will not have any change of control penalties associated with it. We would agree to serve as a stalking horse without fees to allow the company to seek better terms in the market. Based upon your earnings guidance of $1.00 per share for your next fiscal year, we fail to see why the Company would not be able to retire this debt with earnings generated during that timeframe, thereby leaving the Company debt free. It is not too late for this Board to change its mind and there is no urgency, as the existing 6.25% Convertible Notes do not come due until March 1, 2013. We urge you to consider our proposal or superior proposals and not issue unnecessary dilutive securities that may act as a great disservice to shareholders. Very truly yours, CARL C. ICAHN
