This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements in this press release include statements concerning the immediate accretion and other benefits expected from the transaction, the expected timing of the completion of the transaction and management’s anticipated plans and strategies for the combined company. These forward-looking statements are based on current expectations and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the forward-looking statements, including: delays in or failure to obtain any required regulatory approvals with respect to the transaction; failure to consummate or delay in consummating the transaction for other reasons; the possibility that the expected benefits of the transaction may not materialize as expected; failure to successfully integrate the products, R&D capabilities, infrastructure and employees of WD and Hitachi GST; and other risks and uncertainties detailed in WD’s filings with the SEC, including WD’s recent Form 10-Q filed with the SEC on Jan. 28, 2011 for the quarter ended Dec. 31, 2010, to which your attention is directed. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, and WD undertakes no obligation to update these forward-looking statements to reflect subsequent events or circumstances. In addition, this press release contains information about a non-GAAP financial measure. Please note that this non-GAAP financial measure excludes acquisition-related expenses, restructuring charges and amortization of intangibles that we expect to incur in connection with the transaction and following the closing of the transaction. Because these items will not be known to us until on or after the closing of the transaction, we are unable to provide information about the most directly comparable GAAP financial measure. The impact of these excluded items will cause the non-GAAP financial measure to differ materially from the comparable GAAP financial measure.

Certain statements found in this document may constitute “forward-looking statements” as defined in the U.S. Private Securities Litigation Reform Act of 1995. Such “forward-looking statements” reflect management’s current views with respect to certain future events and financial performance and include any statement that does not directly relate to any historical or current fact. Words such as “anticipate,” “believe,” “expect,” “estimate,” “forecast,” “intend,” “plan,” “project” and similar expressions which indicate future events and trends may identify “forward-looking statements.” Such statements are based on currently available information and are subject to various risks and uncertainties that could cause actual results to differ materially from those projected or implied in the “forward-looking statements” and from historical trends. Certain “forward-looking statements” are based upon current assumptions of future events which may not prove to be accurate. Undue reliance should not be placed on “forward-looking statements,” as such statements speak only as of the date of this document.

Factors that could cause actual results to differ materially from those projected or implied in any “forward-looking statement” and from historical trends include, but are not limited to:

economic conditions, including consumer spending and plant and equipment investments in Hitachi’s major markets, particularly Japan, Asia, the United States and Europe, as well as levels of demand in the major industrial sectors which Hitachi serves, including, without limitation, the information, electronics, automotive, construction and financial sectors;

exchange rate fluctuations for the yen and other currencies in which Hitachi makes significant sales or in which Hitachi’s assets and liabilities are denominated, particularly against the U.S. dollar and the euro;

uncertainty as to Hitachi’s ability to access, or access on favorable terms, liquidity or long-term financing;

uncertainty as to general market price levels for equity securities in Japan, declines in which may require Hitachi to write down equity securities that it holds;

increased commoditization of information technology products and digital media-related products and intensifying price competition for such products, particularly in the Components & Devices and the Digital Media & Consumer Products segments;

rapid technological innovation;

fluctuations in the price of raw materials including, without limitation, petroleum and other materials, such as copper, steel, aluminum and synthetic resins and shortages of materials, parts and components;

fluctuations in product demand and industry capacity;

uncertainty as to Hitachi’s ability to implement measures to reduce the potential negative impact of fluctuations in product demand, exchange rates and/or price of raw materials and shortages of materials, parts and components;

uncertainty as to Hitachi’s ability to achieve the anticipated benefits of its strategy to strengthen its Social Innovation Business;

uncertainty as to the success of restructuring efforts to improve management efficiency by divesting or otherwise exiting underperforming businesses and to strengthen competitiveness and other cost reduction measures;

general socio-economic and political conditions and the regulatory and trade environment of countries where Hitachi conducts business, particularly Japan, Asia, the United States and Europe, including, without limitation, direct or indirect restrictions by other nations on imports, or differences in commercial and business customs including, without limitation, contract terms and conditions and labor relations;

uncertainty as to the success of alliances upon which Hitachi depends, some of which Hitachi may not control, with other corporations in the design and development of certain key products;

uncertainty as to Hitachi’s access to, or ability to protect, certain intellectual property rights, particularly those related to electronics and data processing technologies;

uncertainty as to the outcome of litigation, regulatory investigations and other legal proceedings of which the Company, its subsidiaries or its equity method affiliates have become or may become parties;

the possibility of incurring expenses resulting from any defects in products or services of Hitachi;

the possibility of disruption of Hitachi’s operations in Japan by earthquakes or other natural disasters;

uncertainty as to Hitachi’s ability to maintain the integrity of its information systems, as well as Hitachi’s ability to protect its confidential information and that of its customers;

uncertainty as to the accuracy of key assumptions Hitachi uses to valuate its significant employee benefit related costs; and
