Item 1.01.    Entry into a Material Definitive Agreement.
              -------------------------------------------

         On December 28, 2007, InterDigital, Inc. together with certain of its
domestic subsidiaries acting as guarantors (collectively, the Company), entered
into a Second Amendment to Credit Agreement resulting in the continuation of a
two-year $60 million unsecured revolving credit facility (the Credit Agreement).
The Credit Agreement, originally entered into on December 28, 2005 and amended
by the First Amendment, Consent and Joinder to Credit Agreement dated July 2,
2007, is by and among the Company, Bank of America, N.A., as Administrative
Agent, and Citizens Bank of Pennsylvania.

         Borrowings under the Credit Agreement will, at the Company's option,
bear interest at either (i) LIBOR plus 65 basis points or (ii) the higher of the
prime rate or 50 basis points above the federal funds rate. The customary
restrictive financial and operating covenants under the Credit Agreement
continue in full force and effect and include, among other things, that the
Company is required 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, 2007, 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, 2007, 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.
