                                                    Liability and Forecast model

         The components covered by this Enclosure shall solely be used for the
         manufacturing of the Product. See enclosed Excel sheet for liability
         model. Volume figures, component lead-time and price to be updated
         every month

         The model will be applicable for any forecast issued by Sony Ericsson
         as agreed between the parties. Sony Ericsson will issue a revised
         forecast the last business day in each month.

         During the ramp up period, (normally three months following the RTL
         date) Supplier shall review the proposed volume to confirm if the
         necessary capacity is available. This volume proposal to be
         communicated in due time before formal fore cast is issued at the end
         of each month.

         If a revised forecast or the actual call off volume will be lower for a
         certain month than the previously agreed, which will result in excess
         components and such components is not possible to reschedule the
         following applies;

-        Supplier undertakes to keep such material in stock free of charge for
         the first three months after the concerned month. From month four to
         nine after such event Sony Ericsson will cover the interest cost of the
         listed components based upon an reasonable interest rate and reasonable
         warehousing cost for the components listed herein. After this nine
         months period Supplier may claim that this liability undertaking by
         Sony Ericsson shall be executed.

-        In an event of excess material Namtai undertakes to make their best
         effort to cancel any outstanding purchase order of components and to
         resell or reuse any excess component prior to making any claim to Sony
         Ericsson

-        Sony Ericsson will assume liability for scrap of the above components
         provided cause of scrap is solely at Sony Ericsson and prior written
         approval to scrap. Sony Ericsson maximum liability is limited to direct
         material and the maximum liability figure is defined by the liability
         model using the applicable forecast volume, component lead-time and
         prices.

-        Sony Ericsson shall have the option to have the components assembled
         into finished Products at agreed price instead of scrapping the
         components.

         If no notice is given to Sony Ericsson within one week after the
         receipt of revised forecast or actual monthly call off volume it is
         deemed that the revised forecast is accepted (i.e. No claim is to be
         made later nor any objection that the increased volume is not possible
         to meet)

         Any delay in delivery of the Products, caused by Supplier will in full
         release Sony Ericsson from its liability under this amendment.

         Any undertaking of Sony Ericsson and Supplier as defined herein shall
         be limited in time to 30th June 2005.
