Item 1.01.   Entry into a Material Definitive Agreement.

On December 28, 2005, InterDigital Communications Corporation together with
certain of its domestic subsidiaries acting as guarantors (collectively, the
Company), entered into a two-year $60 million unsecured revolving credit
facility (the Credit Agreement). The Credit Agreement was entered into among the
Company, Bank of America, N.A., as Administrative Agent, and Citizens Bank of
Pennsylvania. At the Company's option, borrowings under the Credit Agreement
will bear interest at LIBOR plus 75-90 basis points depending on the level of
borrowing under the credit facility, or at the prime rate or if higher, 50 basis
points above the federal funds rate. The Credit Agreement further contains
certain customary restrictive financial and operating covenants which, among
other things, require the Company to (i) maintain certain minimum cash and
short-term investment levels, (ii) maintain minimum financial performance
requirements as measured by the Company's income or loss before taxes with
certain adjustments, and (iii) limit or prohibit the incurrence of certain
indebtedness and liens, judgments above a threshold amount for which a reserve
is not maintained, and certain other activities outside of the ordinary course
of business. Borrowings under the Credit Agreement can be used for general
corporate purposes including capital expenditures, working capital, letters of
credit, certain permitted acquisitions and investments, cash dividends and stock
repurchases. As of December 28, 2005, the Company did not have any amounts
outstanding under the Credit Agreement.


Item 2.03.   Creation of a Direct Financial Obligation or an Obligation under an
             Off-Balance Sheet Arrangement of a Registrant.

On December 28, 2005, the Company entered into the Credit Agreement, the
material terms and conditions of which are described in Item 1.01 above and are
incorporated herein by reference.
