    Kaohsiung facilities and US$5 million of production to the ex-
	Motorola production building on ASE Chungli campus
  > Within 2 months, Building B on the same campus plans to reach a 
    packaging and test output at an approximately US$5 million 
	monthly run rate.  Within 4 months, Building B plans to add another 
	US$5 million monthly production capacity.

o FC substrate production restoration plan
  > In order to minimize impact on packaging & test 
    operations for our customers, we have asked for 
	assistance from our suppliers to increase shipment
  > Establish Building B as a potential new FC 
    substrate production site and resume production 
    within 4 months with progressive expansion plan 
	to reach an estimated monthly capacity of 6
	million pieces
