Disclaimer

This presentation was prepared as of 03 May 2011 and is current only as of that date.

This presentation includes forward-looking statements and assumptions about the future of Infineon's business and the industry in which we operate. These include statements and assumptions relating to general economic conditions, future developments in the world semiconductor market, our ability to manage our costs and to achieve our growth targets, the resolution of Qimonda's insolvency proceedings and the liabilities we may face as a result of Qimonda's insolvency, the benefits of research and development alliances and activities, our planned levels of future investment, the introduction of new technology at our facilities, our continuing ability to offer commercially viable products, and our expected or projected future results.

These forward-looking statements are subject to a number of uncertainties, such as broader economic developments, including the sustainability of recent improvements in the market environment; trends in demand and prices for semiconductors generally and for our products in particular, as well as for the end-products, such as automobiles and consumer electronics, that incorporate our products; the success of our development efforts, both alone and with partners; the success of our efforts to introduce new production processes at our facilities; the actions of competitors; the continued availability of adequate funds; any mergers, acquisitions or dispositions we may undertake; the outcome of antitrust investigations and litigation matters; and the resolution of Qimonda's insolvency proceedings; as well as the other factors mentioned in this presentation and those disclosed at other occasions.

As a result, Infineon's actual results could differ materially from those contained in or suggested by these forward-looking statements. You are cautioned not to place undue reliance on these forwardlooking statements. Infineon does not undertake any obligation to publicly update or revise any forward-looking statements in light of developments which differ from those anticipated.
