6.Materiality of Information

For purpose of this policy, the definition of "material information" is provided as below: Information is material if its disclosure would be likely to have an impact on the price of a security or if reasonable investors would want to know the information before making an investment decision. In concrete terms, quantitative thresholds which are lower than de-minimis criteria set by the TSE are voluntarily established as an internal guidance to judge the materiality covering the scope of information required to be disclosed pursuant to TSE Timely Disclosure regulations.

1. The damage to the interest of shareholders arising from the immediate or premature release of the information would outweigh the benefits from such release,

3.Decision on disclosure by the Disclosure Committee

In light of the above paragraph 2, the Disclosure Committee will, from time to time, decide whether to disclose or temporarily withhold certain material, non-public information, and if such information is disclosed, the definitive timing and manner of disclosure.

8.Avoidance of selective disclosure and providing fair measures to access information

1. Selective disclosure is the disclosure of material, nonpublic information to any individual or group prior to the broad public dissemination of that information. It is against Mitsui's company policy to selectively disclose material, nonpublic information to people or groups outside of the company at any time, unless those people or groups are covered by confidentiality or nondisclosure agreements.
2. When Mitsui files material information as Timely Disclosure, Mitsui will issue a press release and post it on Mitsui's Website at the same time in order to ensure fair and equitable access by all investors. If certain material, non-public information is unintentionally disclosed by a Spokesperson stipulated in the Article 5 of this policy in such a meeting with a member or members of the investment community, Mitsui will promptly disclose it publicly as Timely Disclosure.

3. The purpose of telephone conversations, one-on-one meetings and meetings with groups of analysts and/or investors is for investors to gain a better understanding of the strategies and fundamentals of the company. Mitsui will not disclose material, nonpublic information selectively in any of these meetings. The contents of company-hosted presentations, including large meetings on earnings release or conferences call, shall be posted on Mitsui's Website for public access.
4. Mitsui observes a three-week quiet period until annual or quarterly earnings are publicly released. During the quiet period, Mitsui does not discuss results of the business or forecast of earnings unless material events subject to Timely Disclosure have occurred.
5. Mitsui's subsidiaries may disclose their earnings on their own Website or by other methods. In order to ensure fair disclosure, such disclosure shall be made in principle on or after the time and date when Mitsui files earnings report for TSE Timely Disclosure, unless otherwise prescribed by laws and regulations. Listed subsidiaries decide the time and date of their earnings release on their own while the same time and date with Mitsui's disclosure is preferable.

9.Responding to market rumors

1. It is Mitsui's basic policy not to comment on market rumors and speculations. The Spokespersons will respond consistently to rumors saying, "It is our policy not to comment on market rumors or speculation."
2. If there is reasonable possibility that a market rumor will cause significant volatility in the prices of securities issued by Mitsui, Mitsui may, after consultation with the TSE, if any, other relevant stock exchanges and/or stock associations, make public statements in accordance with the procedures of TSE Timely Disclosure and relevant rules and regulations of other stock exchanges and stock associations.

10.Handling of forward looking information
