(1)  Financial results for 2002 incorporate results of Rose Records and Tachung
     Records only following the respective January 29, 2002 and September 30,
     2002 acquisitions of the music chains by GigaMedia. As a result,
     consolidated revenues, operating loss, net loss and net loss per share
     figures for 2002 and 2003 periods may not be comparable.

(2)  Net loss excludes minority interests, which comprise 41.4% of GigaMedia's
     offline music distribution business, which operates under the subsidiary
     G-Music Limited ("G-Music").



Consolidated revenues for 2003 increased 28% to NT$3,282.7 million from
NT$2,555.8 million in 2002. Financial results for 2002 incorporate results of
Rose Records and Tachung Records only following the respective January 29, 2002
and September 30, 2002 acquisitions of the music chains by GigaMedia. As a
result, consolidated revenues, operating loss, net loss and net loss per share
figures for 2002 and 2003 periods may not be comparable.

Consolidated operating loss for 2003 decreased 41% to NT$485.1 million from
NT$824.7 million in 2002. Fiscal year 2002 consolidated operating loss included
charges incurred during the fourth quarter of 2002 amounting to approximately
NT$323.6 million for goodwill related to the purchase of the Company's offline
music distribution business and impairment of GigaMedia's investment in an
online music company, GigaMusic.com Limited. As a result, year-over-year
consolidated operating loss may not be comparable.

Consolidated net loss for 2003 decreased 25% to NT$481.4 million from NT$638
million in 2002. Consolidated net loss excludes minority interests, which
comprise 41.4% of GigaMedia's offline music distribution business, which
operates under the subsidiary G-Music.

Fourth Quarter Results

For the fourth quarter of 2003, consolidated revenues increased 5% to NT$842
million from NT$801 million in the third quarter of 2003, primarily due to
improved sales in G-Music. G-Music recorded revenues of NT$663 million during
the period compared to NT$634.6 million in the third quarter.

Consolidated operating loss in the fourth quarter of 2003 increased 180% to
NT$246 million from NT$87.9 million in the third quarter of 2003. The increase
in consolidated operating loss during the quarter was mainly attributable to
charges consisting of NT$99 million for slow-moving music inventory, NT$53.6
million for reevaluation of hardware related to one-way cable modem service, and
NT$25.4 million for goodwill related to the purchase of GigaMedia's offline
music distribution business.

Consolidated net loss in the fourth quarter of 2003 increased 194% to NT$266.8
million from NT$90.8 million in the third quarter of 2003. Net loss excludes
minority interests, which comprise 41.4% of G-Music.

Balance Sheet

Cash and other cash equivalents at the end of the fourth quarter of 2003 totaled
NT$1,198.9 million, not including additional short-term investments totaling
NT$983.6 million, compared to NT$1,240.2 million and NT$919.8 million,
respectively, at the previous period-end.

(1)  G-Music results incorporate results of Rose Records and Tachung Records
     only following the respective January 29, 2002 and September 30, 2002
     acquisitions of the music chains by GigaMedia. As a result, revenues,
     operating loss, and net loss figures for 2002 and 2003 periods may not be
     comparable.


Total revenues for the quarter ended December 31, 2003 were NT$663 million, up
4% from the NT$634.6 million recorded during the prior period. Fourth quarter
sales improved over the third quarter mainly due to a recovery from the negative
impact of SARS, which delayed a significant number of artist releases until the
fourth quarter. Overall, G-Music revenues continued to be negatively impacted by
digital piracy. G-Music results incorporate results of Rose Records and Tachung
Records only following the respective January 29, 2002 and September 30, 2002
acquisitions of the music chains by GigaMedia. As a result, revenues, operating
loss, and net loss figures for 2002 and 2003 periods may not be comparable.

Operating loss for the quarter ended December 31, 2003 was NT$139.4 million.
This represented an increased operating loss of approximately NT$113.2 million
over the third quarter, due primarily to a slow-moving inventory charge of
approximately NT$99 million recorded during the fourth quarter of 2003.

Net loss increased from NT$23.9 million in the third quarter of 2003 to NT$157.4
million in the fourth quarter of 2003, primarily due to the aforementioned
inventory charge incurred during the fourth quarter. Net loss for the year
declined by 24% to NT$258.4 million from NT$340.7 million in 2002. Net loss for
2003 was disproportionately smaller than net loss for 2002 because net loss in
2002 included a charge of approximately NT$242.9 million for goodwill related to
the purchase of GigaMedia's offline music distribution business.

REVENUES                                          179        166.4        673.8       665.7
OPERATING INCOME (LOSS)                          (106.6)     (61.7)      (238)        483.9
NET INCOME (LOSS)                                (174.6)     (76.8)      (330)       (366.8)



Total revenues for the quarter ended December 31, 2003 increased 8% to NT$179
million from NT$166.4 million during the previous quarter. Subscribers and
blended ARPU during the period were relatively flat at approximately 103,000 and
approximately NT$428 per month, respectively. In order to offset price drops and
achieve revenue growth, the Company is focused on migrating users to higher
specification products and phasing out one-way cable modem service.

Operating loss in the fourth quarter of 2003 increased by 73% to NT$106.6
million from NT$61.7 million in the third quarter of 2003, primarily due to a
charge of approximately NT$53.6 million incurred during the fourth quarter in
connection with the revaluation of hardware related to one-way cable modem
service.

Net loss increased in the fourth quarter of 2003 to NT$174.6 million from a net
loss of NT$76.8 million in the prior period, resulting primarily from the
aforementioned one-way cable modem hardware revaluation charge, as well as
charges incurred during the quarter of approximately NT$84.8 million for
investment in online music company Rock Internet Corporation and disposal of
property and assets.

BUSINESS OUTLOOK

The following forward-looking statements reflect GigaMedia's expectations as of
April 9, 2004. Given potential changes in economic conditions and consumer
spending, the evolving nature of broadband, fluctuations in Taiwan's recorded
music market and various other risk factors, including those discussed in our
20-F filing with the U.S. Securities and Exchange Commission referenced below,
actual results may differ materially.

GigaMedia is providing the following outlook for the first quarter of 2004:

o    GigaMedia expects continued weakness in the music distribution market. For
     the first quarter of 2004, total revenues in this business segment are
     expected to be flat, with operating loss flat to slightly improved.

o    GigaMedia's expects continued strong price competition in the broadband ISP




     market. For the first quarter of 2004, total revenues and costs and
     expenses in this business segment are expected to increase slightly, with
     flat to slightly improved subscriber numbers.
