         The Schedule 13D filed on June 29, 1996, as previously amended
         (collectively, the "Prior Statement") is hereby amended as set forth in
         this Amendment No. 5. Except as otherwise indicated, capitalized terms
         which are used but not defined herein shall have the meanings ascribed
         in the Prior Statement.

Item 1. Security and Issuer.

         No modification, except that the Issuer has changed its name to TOR

Item 2. Identity and Background.

         As of the date of this Amendment, the officers and directors of Megamin

         Lim Si Boon is a citizen of Malaysia and serves as Managing Director of

         Tan Chin Yong is a citizen of Brunei and resident of Malaysia. He
serves as a director of Meru Valley Resort Berhad.

         As of the date of this Amendment, the directors of Bonanza Venture
Holdings Sdn Bhd, a holding company that owns the Company and is ultimately
controlled by Lim Keng Kay, are as follows:

         Lim Keng Kay and Chong Wai Lin, as previously reported;

         Lim Kheng Loy is a citizen of Malaysia. He is an architect for Gerak

Item 3. Source and Amount of Funds or Other Consideration.

         No modification.

Item 4. Purpose of Transaction.

         The Prior Statement related to transactions in which the Company
acquired shares of the Issuer over a period of several years, most recently in
2000. The Company has more recently reviewed its ownership position in light of
market conditions, the financial performance of the Issuer, the improved prices
and volumes at which the Issuer's shares have traded, and numerous other
factors. As a result of that review, the Company has determined to dispose of a
portion of its position and has sold shares pursuant to the exemption provided
in Rule 144 under the Securities Act of 1933. Sales which have occurred in the
sixty day period preceding the filing of this Amendment (an aggregate of 50,000
shares) are reflected in the response to Item 5.

         To the extent that the Company considers market conditions conducive to
such sales, the Company intends to continue selling shares from time to time in
accordance with, and subject to, the limitations on the volume of selling under
Rule 144. In addition, the Company may sell additional shares in private
transactions which are not subject to the volume limitations imposed by Rule
144; if any such transactions are consummated, the shares sold in private
transactions would be subject to restrictions on resale.
