         JKK Inc., a British Virgin Islands corporation ("JKK"), and Leslie Koo,
a citizen of Taiwan, the Republic of China (JKK and Leslie Koo are herein after
referred to as the "Reporting Persons"), hereby amend and supplement the
statement on Schedule 13D previously filed by them, with respect to the Ordinary
Shares, par value NT$10 per share (the "Ordinary Shares"), of GigaMedia Limited,
a Singapore corporation, (the "Issuer"), beneficially owned by them. Except as
amended and supplemented hereby, the statement on Schedule 13D, as heretofore
amended and supplemented, remains in full force and effect.


Item 5.  Interest in Securities of the Issuer.
         ------------------------------------

         On February 20, 2003 JKK Inc., a British Virgin Islands corporation,
sold 4,616,389 shares of Ordinary Shares at US$0.87 per purchased share pursuant
to Regulation S. From February 10, 2003 to March 31, 2003, JKK sold 1,038,284
shares in the Nasdaq National Market.

As of the date of the filing of this Statement, JKK beneficially owns, and
Leslie Koo may be deemed to beneficially own through JKK, 5, 161,716 shares of
Ordinary Shares, which represents approximately 10.29% the outstanding Ordinary

as of June 30, 2002, in the Issuer's Form 20-F Report for the year ended
December 31, 2001. Leslie Koo, a director of Issuer, holds options to purchase
100,000 of these shares at $24.3 per share, and Chester Koo, an ex-director of
the Issuer and Chairman of Issuer, passed away on December 24, 2001 and the
options held by him is therefore invalid.
