NOTE


N1      As a result of an over-allotment exercise by the listing
        underwriters of Sino Stride Technology (Holdings) Limited
        ("SST")(GEM code: 8177) on 22 August 2002, the percentage
        shareholding of Singapore Technologies Electronics Limited
        (ST Elect) has been diluted from 10% to 9.96%, although the
        number of shares held by ST Elect remains unchanged.  ST
        Elect therefore ceased to have notifiable interest in SST.
        Temasek Holdings (Private) Limited has also ceased to
        be a substantial shareholder of SST.
