InterDigital's Board Authorizes Buyback of up to One Million Shares of
Common Stock and Redemption of $2.50 Cumulative Convertible Preferred
Stock

    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--June 10, 2004--InterDigital
Communications Corporation (Nasdaq:IDCC), a leading architect,
designer and provider of wireless technology and product platforms,
today announced that its Board of Directors approved the repurchase of
up to one million shares of the Company's outstanding Common Stock at
its recent Board meeting. The shares may be repurchased from
time-to-time through open-market purchases or prearranged plans. The
amount and timing of purchases will be based on a variety of factors,
including potential stock acquisition price, cash requirements,
acquisition opportunities, strategic investments and other market and
economic factors. A portion of the repurchased shares may be used for
the Company's equity-based incentive, retention and other benefit
programs and the balance will be available for other general corporate
purposes.
    The Company also announced that it will redeem all of its $2.50
Cumulative Convertible Preferred Stock ("Preferred Stock") outstanding
as of June 15, 2004. As of June 4, 2004, the number of shares of
Preferred Stock outstanding was 52,762. The Redemption Date of the
Preferred Stock will be July 19, 2004. The redemption price for the
Preferred Stock will be $25.00 per share plus accrued dividends from
June 1, 2004 through the Redemption Date. Holders of the Preferred
Stock also may exercise their option to convert their shares into
Common Stock at any time prior to the close of business (5:00 p.m.
EDT) on July 16, 2004 at a conversion rate of 2.08 shares of
InterDigital Common Stock for each share of Preferred Stock. Upon
conversion, InterDigital will pay cash in lieu of fractional shares of
Common Stock.
    Harry Campagna, Chairman of the Board, stated, "The Board of
Directors' decision to repurchase another million common shares and
redeem the outstanding Preferred Stock reflects our continued
confidence in the Company's future. We repurchased two million shares
in 2003 and remain convinced that additional investment in our own
Common Stock is a very appropriate one."
