Date:December 27, 2004 MITSUI & CO., LTD. By: /s/ Tasuku Kondo ------------------------------ Name: Tasuku Kondo Title: Executive Director Executive Vice President Chief Financial Officer December 24, 2004 Mitsui & Co., Ltd For Immediate Release To whom it may concern ANNOUNCEMENT OF THE RESULTS OF THE INTERNAL INVESTIGATION IN CONNECTION WITH THE DIESEL PARTICULATE FILTER ("DPF") INCIDENT TOGETHER WITH OUR COURSE OF ACTIONS BASED ON ITS RESULTS Reference is made to our announcements dated November 22, 2004 and December 1, 2004 regarding the Diesel Particulate Filter ("DPF") incident. Immediately after the identification of the incident, we established an internal investigation committee chaired by outside counsel. We would like to report on the results of the investigation, together with our course of actions based on its results. THE RESULT OF THE INTERNAL INVESTIGATION The internal investigation committee is chaired by Mr. Seinei Gondo and consists of 16 outside lawyers. During the period from November 16, 2004 to December 20, 2004, they thoroughly interviewed 27 individuals and reconciled their findings with vast volumes of related documents. It was reported that the total time spent on the investigation came up to about 1,600 hours. The investigation report is more than 2,000 pages in length, including attachments. The 27 individuals that were interviewed included those who were not directly involved in the incident as well as those who were. In order to protect the privacy of the 27 interviewees, we will not disclose the full text of the investigation report. The investigation covered not only the data falsifications of the DPF incident ("Data Falsifications") but also fraudulent activities ("Fraudulent Activities") that took place in PUREarth Incorporated ("PE"), Mitsui's wholly owned subsidiary, which were identified during the course of a periodic internal audit that resulted in the confession on the Data Falsifications from one of Mitsui's employees. The investigation report concluded that there were no more than four individuals who were involved in the Data Falsifications. The four individuals consisted of two Mitsui employees, a PE officer who used to be a contracted employee of Mitsui, and a PE employee. We had previously mentioned that three individuals seemed to have been involved, two from Mitsui and one from PE, but the investigation committee identified and reported on the involvement of the fourth individual, a PE employee. 1 With respect to the Fraudulent Activities in PE, the investigation committee reported on the suspicion that the PE officer and another PE employee acted in breach of their fiduciary duty and may have caused financial damage to PE. The PE employee involved in such Fraudulent Activities is a separate individual from the PE employee involved in the Data Falsifications. OUR COURSE OF ACTIONS BASED UPON THE RESULTS OF THE INTERNAL INVESTIGATION Based on the results of the investigation, Mitsui decided on the disciplinary dismissal of the two employees who were unquestionably involved in the Data Falsifications. PE decided on the disciplinary dismissal of each of the two employees who were involved in the Data Falsifications and the Fraudulent Activities, respectively. At its meeting of the board of directors today, PE also decided to file criminal complaints against the PE officer and the PE employee who were involved in the Fraudulent Activities. The PE officer had already resigned from PE as of November 30, 2004, but PE reserves its right to pursue his liability as PE officer and director. We have so far taken disciplinary and legal actions only on those individuals who had been directly involved in the Data Falsifications and the Fraudulent Activities. However, we also recognize the responsibility of our management team which was unable to prevent the occurrence of these grave incidents, and will take relevant actions in this respect in consideration of further internal analyses and evaluations based on the results of the investigation as well as the directions of relevant administrations including the results of criminal complaints filed by the Tokyo Metropolitan Government and three other prefectural governments. We will once again report on these further actions at the earliest appropriate opportunity. We would have to work honestly and diligently a long way with high ethical standards before we could recover the trust and confidence which were lost through the incident. In this connection, We have come up with the following list of measures to prevent the recurrence of similar incidents in future. 1. Overhauling the internal controls and compliance mechanisms on a consolidated basis 2. Facilitating the utilization of whistle-blowing system involving subsidiaries by ensuring anonymity 3. Enhancing the internal evaluation process on new businesses related to R&D, the environment and any businesses in which government subsidies are involved. Outside experts will be brought in where it is identified that there is lack of internal expertise. 4. Increasing the frequency and the scope of internal auditing by the Internal Auditing Division, which reports directly to the President, including the introduction of unscheduled auditing 5. Strengthening the internal control of subsidiaries by appointing corporate auditors from Mitsui who are not affiliated with the business affairs of such subsidiaries 6. Reviewing and strictly applying the internal rules on disciplinary actions 2 Soon after the announcement on November 22, 2004, we established the DPF Response Headquarters which now involves 260 employees working full time to take responsive measures outlined in the announcement made on December 1, 2004, namely, (1) free replacement of DPFs, (2) remedial measures other than DPF replacement, and (3) compensation of subsidies. We have so far received 1,600 inquiries from our users and sales agents over telephone or fax, and visited more than 400 of them. Through such efforts, we have been able to cover almost all of our DPF users directly or indirectly. Our staff have also visited providers of subsidies relating to our DPFs, including state and local governments as well as industry associations, whose directions and support have been instrumental in implementing these responsive measures. Again, Mitsui expresses our utmost regret to our DPF users and all the parties concerned as well as the citizens and the local communities for the occurrence of this incident.
