 Amendment 1: Page.6
１．Qualitative Information on the consolidated Business Results (４) Risk factors

 <As Originally Reported>
DETERIORATION IN OUR RELATIONSHIP WITH SOFTBANK BB CORP. COULD RESULT IN A DECREASE IN SALES OF OUR WIDE RANGE OF PRODUCTS AND SERVICES.
We depend on our relationship with SOFTBANK BB (formerly SOFTBANK COMMERCE CORP.), which has played an instrumental role in the development of our business in Japan. SOFTBANK BB also has close relationships with many resellers and systems integrators through which we sell our wide range of products and services to corporate end users in Japan. An adverse change in our relationship with SOFTBANK BB would result in decreased sales to SOFTBANK BB and could disrupt our relationship with many resellers of our wide range of products and services. This could make it difficult for us to market our wide range of products and services in Japan. Sales to SOFTBANK BB totaled approximately (Yen) 10.4 billion, or 10.9%, of our net sales in fiscal 2009, approximately (Yen) 12.3 billion, or 13.0%, of our net sales in fiscal 2010, and approximately (Yen) 12.5 billion, or 13.0%, of our net sales in fiscal 2011. Because of our dependence on SOFTBANK BB, the price of shares could fall as a result of adverse events affecting SOFTBANK BB, even if the events do not relate directly to us.
