End

Regulations on Solicitation

This press release has been prepared for the purpose of informing the public of the Tender Offer and has not been prepared for the purpose of soliciting an offer to sell, or making an offer to purchase, any securities. If shareholders wish to make an offer to sell their shares in the Tender Offer, they should first read the Tender Offer Explanation Statement for the Tender Offer and offer their shares or stock options for sale at their own discretion. This press release shall neither be, nor constitute a part of, an offer to sell or purchase, or a solicitation of an offer to sell or purchase, any securities, and neither this press release (or a part thereof) nor its distribution shall be interpreted to be the basis of any agreement in relation to the Tender Offer, and this press release may not be relied on at the time of entering into any such agreement.

Future Prospects

This press release, including the descriptions regarding the future business of the Offeror and other companies, may contain expressions for the future prospects such as “anticipate,” “expect,” “intend,” “plan,” “believe” and “assume,” and other similar expressions. These expressions are based on the Offeror’s current expectations as to the businesses, and may change depending on the future circumstances. Regarding the information herein, the Offeror undertakes no obligation to change the expressions for the future prospects into those for the actual events by reflecting the actual business performance, various circumstances and changes in conditions, etc. These expressions refer to, and this press release includes, statements that fall under “forward-looking statements” as defined in Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”). Due to the known and unknown risks and uncertainties, the actual results might differ significantly from the statements that are implicitly or explicitly forward-looking. The Offeror and its affiliates do not guarantee for such implicit and explicit forward-looking statements to materialize. The “forward-looking statements” in this press release were prepared based on the information obtained by the Offeror as of the date hereof, unless required by law, the Offeror and its affiliates are not obligated to amend or revise such forward-looking statements to reflect future matters and situation.

US Regulations

Although the Tender Offer will be conducted in accordance with the procedures and information disclosure standards prescribed under Japanese law, those procedures and standards may differ from the procedures and information disclosure standards in the United States. In particular, Sections 13(e) and 14(d) of the U.S. Exchange Act, and the rules prescribed thereunder, do not apply to the Tender Offer, and therefore the Tender Offer does not conform to those procedures and standards. In addition, the financial information contained in this press release was prepared based on Japanese accounting standards and not based on U.S. accounting standards, and thus may not necessarily be comparable to the content of any financial information prepared based on U.S. accounting standards. It may be difficult to enforce any right or claim arising under U.S. federal securities laws because, among other reasons, the Offeror and the Target Company are incorporated outside the United States and some or all of their directors are non-U.S. residents. Shareholders may not be able to sue a company outside the United States and its directors in a non-U.S. court for violations of U.S. securities laws. Furthermore, there is no guarantee that shareholders will be able to compel a company outside the United States or its subsidiaries and affiliates to subject themselves to the jurisdiction of a U.S. court.

Unless otherwise specified, all procedures relating to the Tender Offer shall be conducted entirely in Japanese. While some or all of the documentation relating to the Tender Offer will be prepared in English, if there is any inconsistency between the English documentation and the Japanese documentation, the Japanese documentation will prevail.

The Offeror, the financial advisors to the Offeror, and the Tender Offer Agent (including their respective affiliates) may purchase the Target Shares by means other than the Tender Offer to the extent permitted by Rule 14e-5(b) of the U.S. Exchange Act, applicable laws and regulations in Japan, and other applicable laws and regulations. Such purchases may be made at the market price through market transactions, or at a price determined by negotiation outside of the market.

Other Countries

In certain countries or regions, the announcement, issue or distribution of this press release may be restricted by laws or regulations. In such cases, you are required to be aware of such restrictions and comply with them. This press release does not constitute any solicitation of an offer to sell or offer to purchase shares in relation to the Tender Offer, and shall be considered as a mere distribution of informative materials.

This press release is not for release, publication or distribution, in whole or in part in, into or from any jurisdiction where doing so would constitute a violation of the relevant laws or regulations of that jurisdiction.
