                                    PART IV


It is anticipated that there will be a significant change in the Registrant's
results of operations from 2001 to 2002 which will be reflected by the earnings
statement in the subject report. The Registrant publishes its financial
statements in New Taiwan dollars, the lawful currency of Taiwan. The references
below to "US$" are to United States dollars and references to "NT$" are to New
Taiwan dollars. All translations from New Taiwan dollars to United States
dollars were made on the basis of the noon buying rate in The City of New York
for cable transfers in NT dollar per U.S. dollar as certified for customs
purposes by the Federal Reserve Bank of New York on December 31, 2002 of
NT$34.70 = US$1.00.

The Registrant's total sales revenue increased 522% to NT$2.6 billion (US$73.7
million) in 2002, from NT$411.0 million in 2001. Costs and expenses increased
38% to NT$3.4 billion (US$97.4 million) in 2002 from NT$2.4 billion in 2001. The
Registrant recorded net loss of NT$638.0 million (US$18.4 million) in 2002
compared to a net loss of NT$1.8 billion in 2001.
