[Translation] Ref. PDI.B.02.92/98 8 September, 1998 To : President The Stock Exchange of Thailand Re. : Correction of investment and commitment in an affiliated company and notification of additional resolution of the board of directors We refer to our letters, ref. PDI.B.02.86/98 of 1 September 1998 and ref. PDI.B.02.60/96 of 21 April 1996. We would like to inform the SET that the investment and commitment to be deferred for written-off in Asia Investment (1995) Co., Ltd., in which PDI has 20% shareholding, should read approx.Bt1.02m instead of Bt0.1m as previously stated. In addition, PDI's board of directors at its meeting, No. 5/1998 on 31 August 1998 has also resolved to rectify a transfer of total 20% shareholding in Erawan Mining Co., Ltd., equal to 3,067,406 shares to a new group of investors, namely Mr. David M. Docherty and colleagues. The existing shareholders in Erawan Mining Co. Ltd. - i.e. PDI and PD Puthep Ltd., its foreign partner, jointly signed in Purchase Agreement with the new investors on 29 June 1998. In so doing, PDI will receive 5% of total net earnings if the new group can successfully develop prospecting areas in Petchabul province into mining operation in the future. And since PDI's earlier 20% shareholding in Erawan Mining had not been paid up and booked (unless a decision on feasibility study would be reached); therefore, PDI has not any investment or commitment to be written off. Yours truly, - Signature - (Arsa Sarasin) Executive Chairman & CEO
