                              ISRC / SILICON IMAGE
                       RESEARCH AND DEVELOPMENT AGREEMENT

This Research and Development Agreement (the "AGREEMENT") is made this 1st
day of January, 2000 (the "EFFECTIVE DATE") between Silicon Image, Inc., a
California corporation with its principal place of business at 10131 Bubb
Road, Cupertino, California 95014 ("SII") and the Inter-University
Semiconductor Research Center of Seoul National University, located in Seoul,
Korea ("ISRC"). (As used herein, "PARTY" or "PARTIES" will refer to SiI,
ISRC, or both, as the case may be).

1.       OBJECTIVE.

         SiI requests that ISRC conduct research and development on
         "Multi-Gigabit Serial Links", Integrated Network and Host Interface
         Functions with Multi-Gigabit Serial Link and Embedded DRAM, and on
         "1000BASE-T Gigabit Ethernet PHY Chip." The specific objectives of the
         research to be conducted are described in the research project proposal
         attached as Exhibit A (the "PROJECT").

2.       PERIOD OF THE RESEARCH.

         This Agreement will provide funding for research activities for a
         period of two (2) years commencing January 1, 2000 and ending December
         31, 2001.

3.       OBLIGATIONS BY ISRC.

         3.1.     PROJECT LEADER. ISRC will designate Professor Deog-Kyoon Jeong
                  as the faculty member in charge of the Project. Mr. Jeong will
                  be the primary technical and university contact for SiI for
                  all technical and administrative issues related to the Project
                  for the Term of this Agreement ("PROJECT LEADER"). Should
                  Professor Jeong's employment with ISRC cease, for any reason,
                  SiI reserves the right to designate a new Project Leader, if
                  SiI so desires.

         3.2.     USE OF RESEARCH FUNDS. The research funds provided by SiI to
                  ISRC will be under the sole discretion of the Project Leader
                  and will be used to cover expenses directly or indirectly
                  related to the Project. ISRC will use its best efforts to
                  attain the specific objectives of the Project. Should funds be
                  used to expand ISRC's facilities to perform the Project, ISRC
                  agrees to provide office and laboratory space equal in value
                  to the funds utilized to expand ISRC's facilities. The office
                  and laboratory space will be provided and solely reserved for
                  SiI to utilize at its discretion for 10 years. In no event
                  will more than 50% of the research funds be used to expand
                  ISRC's facilities, without prior written approval from SiI. A
                  complete accounting of the use of the research funds and
                  expense reports with receipts for any equipment purchased must
                  be provided in the final report, described below.

                  the prior written consent of the other party, which shall not
                  be unreasonably withheld or delayed; provided, however, that
                  SiI may assign its rights and delegate its duties under this
                  Agreement to a third party in connection with an acquisition,
                  merger, or corporate reorganization without the prior written
                  consent of ISRC. Any other attempted assignment or delegation
                  without such written consent will be void. The rights and
                  liabilities of the parties under this Agreement will bind and
                  inure to the benefit of the parties' respective successors and
                  permitted assigns.

         10.7     RELATIONSHIP OF PARTIES. All current and future Project Staff
                  are independent contractors for SiI and this Agreement will
