FORWARD LOOKING STATEMENTS
This news release contains certain forward-looking statements, including statements about our business prospects and our expectations regarding our business, demand trends and expected growth, including in the Enterprise and Client Computing markets, that are based on our current expectations and are subject to numerous risks and uncertainties that may cause these forward-looking statements to be inaccurate and may significantly harm our business, financial condition and results of operations. Risks that may cause these forward-looking statements to be inaccurate include among others:

• competitive pricing pressures, resulting in lower average selling prices and lower or negative product gross margins;
• unpredictable or changing demand for our products, particularly for certain form factors, such as embedded flash memory, or capacities, or the mix of X2 and X3 technologies;
• excess captive memory output or capacity which could result in write-downs for excess inventory, lower of cost or market charges, fixed costs associated with under-utilized capacity, or other consequences;
• increased memory component and other costs as a result of currency exchange rate fluctuations to the U.S. dollar, particularly with respect to the Japanese yen;
• lower than anticipated demand, including due to general economic weakness in our markets;
• expansion of industry supply, including low-grade supply useable in limited markets, creating excess supply, causing our average selling prices to decline faster than our costs;
• insufficient supply from captive flash memory sources, inability to obtain non-captive flash memory supply of the right product mix and quality in the time frame necessary to meet demand, or inability to realize a positive margin on non-captive purchases; and
• the other risks detailed from time-to-time under the caption "Risk Factors" and elsewhere in our Securities and Exchange Commission filings and reports, including, but not limited to, our Quarterly Report on Form 10-Q for the fiscal quarter ended October 2, 2011.
