　　Seoul, Korea and Shanghai, China.--(PR Newswire)—February 20, 2004--SINA Corporation (Nasdaq:SINA), a leading online media company and value-added information service provider for China and for global Chinese communities, announced today that it has entered into a license agreement with Plenus Inc. (KOSDAQ: 37150) to introduce game portal service in China. Plenus, a leading entertainment company, offers casual games and community services through NetMarble (www.netmarble.net). With over 22 million registered users and 70 billion Korean Wons (US$68 million) in revenue in 2003, NetMarble is one of the most successful game portals in Korea.

Currently, online game market in China consists mostly of massive multi-player online role-playing games (MMORPG). However, as has been shown in Korea, over the next few years, casual games and game portal business could become an important part in the overall online game market in China.

　　"With the rapid advancement of Internet and online game industry in China, we believe that the growth of casual games and game portals will soon follow," said Wang Yan, CEO of SINA. "Our partnership with Plenus will give us the technology to develop our own games which represents a significant step forward in our strategy to posses in-house game development capabilities.”

　　Under the license agreement, SINA will pay US$2 million in up front royalty with a running royalty of 10 percent of the net revenue of the game portal in China. The license period is five years and will be renewable. The transaction is subject to customary closing conditions including regulatory approvals and is expected to be completed in the first quarter of 2004.
