Item 1.01.        Entry into a Material Definitive Agreement.

On May 31, 2006, the Compensation Committee of Board of Directors of
InterDigital Communications Corporation (the "Company") approved an increase in
the annual base salary of the Company's Chief Executive Officer, William J.
Merritt, from $400,000 to $450,000. The increase, which is to take effect
immediately, was based on recognition of Mr. Merritt's excellent management of
the Company over the first half of 2006, formulation and achievement of goals
and the Company's product initiative. The decision also took account of
independently compiled data provided to the Compensation Committee indicating
that Mr. Merritt's base salary was below industry peers.


Pursuant to the requirements of the Securities Exchange Act of 1934, the
Registrant has duly caused this Current Report on Form 8-K to be signed on its
behalf by the undersigned hereunto duly authorized.
