On April 10, 2002, the Board of Directors of InterDigital Communications Corporation (the "Company") made a determination to engage PricewaterhouseCoopers LLP ("PwC") to serve as the Company's independent public accountants for the fiscal year 2002 and no longer engage Arthur Andersen LLP ("Arthur Andersen") in such capacity. The determination was based upon the recommendation of the Audit Committee, which evaluated PwC's experience and expertise as well suited to the auditing and financial reporting needs of InterDigital's business. The appointment of PwC is subject to shareholder ratification at the Company's 2002 Annual Meeting of Shareholders scheduled to be held on June 4, 2002.

Arthur Andersen's report on the Company's consolidated financial statements for the year ended December 31, 2001 was filed on March 29, 2002 with the Company's Annual Report on Form 10-K for the year ended December 31, 2001. During the years ended December 31, 2001 and 2000 and through the filing date of this Current Report on Form 8-K, there were no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Arthur Andersen's satisfaction, would have caused them to make reference to the subject matter in connection with their report on the Company's consolidated financial statements for such years; and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K. The Company provided Arthur Andersen with a copy of the foregoing disclosures.
