to InterDigital's Board of Directors in December 2003, will continue
to serve his term until the June 7, 2007 Annual Meeting of
Shareholders.

    "I would like to thank Al for his dedication to InterDigital's
Board, the company and its shareholders," commented Mr. Harry

Technology Consulting Associates, Inc., a consulting firm he founded

Board during its period of greatest growth," commented Mr. Zabarsky.
"InterDigital has a bright future, both as a technology licensor and
in connection with its more recent emergence as a supplier of ASIC
solutions. I have every confidence that the management team and Board
