Cautionary Note Regarding Forward-Looking Statements

This Current Report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, each as amended. These forward-looking statements include, but are not limited to, statements related to the proposed offering of the Notes and the anticipated use of proceeds therefrom. These forward-looking statements are based on information available to the Company as of the date of this Current Report. Current expectations, forecasts and assumptions involve a number of risks and uncertainties that could cause actual results to differ materially from those anticipated by these forward-looking statements. Such risks and uncertainties include a variety of factors, some of which are beyond the Company’s control. In particular, global economic conditions may pose a risk to our operating and financial performance as consumers and businesses may defer purchases in response to uncertain financial conditions. Such risks and uncertainties also include, but are not limited to, the impact of the variable demand; the possible impact of natural disasters, such as were recently experienced in Japan, on our sources of supply or on end demand for our products; dependence on our ability to successfully qualify, manufacture and sell our disk drive products in increasing volumes on a cost-effective basis and with acceptable quality, particularly our new disk drive products with lower cost structures; the risk that our recently announced transaction with Samsung Electronics Co., Ltd. will not be consummated and the risk that we will incur significant costs in connection with the transaction; the impact of competitive product announcements and our ability to achieve projected cost savings. Information concerning risks, uncertainties and other factors that could cause results to differ materially from those projected in the forward-looking statements is contained in the Company’s Quarterly Reports on Form 10-Q as filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 3, 2010, February 3, 2011 and May 3, 2011, our Annual Report on Form 10-K as filed with the SEC on August 20, 2010 and Amendment No. 1 to our Annual Report on Form 10-K as filed with the SEC on October 6, 2010, respectively, which statements are incorporated into this Current Report by reference. These forward-looking statements should not be relied upon as representing the Company’s views as of any subsequent date and the Company undertakes no obligation to update forward-looking statements to reflect events or circumstances after the date they were made.
