3.  Policy on Investment in Subsidiary and Associated Companies

Any significant share acquisitions or investment in projects will be
considered and approved by the Board of Directors of each company
concerned prior to recommendation to shareholders for consideration.

Management Policy

Major shareholders normally appoint their representatives to the board
of directors of the subsidiary and associated companies. Director seats
will be allocated in proportion with the investment ratio. Each
subsidiary and associated company, therefore, has its own board of
directors whose policies and regulations are guided. However, the
Company, as the major shareholder, has control in the subsidiary’s
business operations.
