INTERDIGITAL COMMUNICATIONS CORPORATION

STOCK OPTION AGREEMENT

This Stock Option Agreement (“Agreement”) is made as of the      day of                     , 20     (“Grant Date”) between                              (“Optionee”) and InterDigital Communications Corporation (“Company”), a Pennsylvania corporation.

WHEREAS, the Company desires to grant Optionee stock options and Optionee desires to accept such options as further specified herein.

NOW, THEREFORE in consideration of the mutual covenants contained herein, and intending to be legally bound, the parties hereby agree as follows:

1. A NON-QUALIFIED Stock Option (“Option”) for a total of                              (            ) shares of Common Stock, par value of $0.01 per share, of the Company is hereby granted to Optionee subject to all of the terms and provisions of the Company’s 2000 Stock Award and Incentive Plan (“Plan”), which Plan is incorporated herein by reference.

2. The Option price as determined by the Committee, as defined in Paragraph 5 below, with authority for administering the Plan for the Company is $             per share, the market price of the Company’s Common Stock on the Grant Date.

3. The term of the Option shall be the period from the Grant Date to                     , 20    , subject to extension or to earlier termination and/or acceleration as provided in the Plan and this Agreement (“Option Term”). The Option (or an installment thereof) shall be exercisable only during the Option Term, subject to vesting as follows:

4. Upon termination of Optionee’s employment with the Company or a subsidiary of the Company for any reason other than death or disability, that portion of the Option exercisable on the date of said termination shall be exercisable by Optionee (or in the case of Optionee’s death subsequent to termination, by Optionee’s executor(s) or administrator(s)) for a period of six (6) months from the date of termination. Notwithstanding the preceding sentence, subject to the other terms of the Plan and this Agreement, if Optionee’s employment with the Company terminates (including due to death or disability) and Optionee has been employed by the Company for at least ten (10) years as of the date of such termination, the Option, to the extent vested and exercisable as of the date of termination of employment, will not expire prior to the end of the Option’s term as a result of the termination of employment.

5. If the Optionee’s employment with the Company terminates and the Compensation & Stock Option Committee or the Company’s Board of Directors (in either case, referred to herein as the “Committee”), in its sole discretion, makes a determination, either prior to such termination or following such termination but during the term of the Option, that, during the Optionee’s employment with the Company, Optionee has:

(a) engaged in any type of disloyalty to the Company, including without limitation, insubordination, fraud, embezzlement, theft or dishonesty in the course of Optionee’s employment or engagement; or

(b) been convicted of a felony; or

(c) breached the terms of any written confidentiality agreement or any non-competition agreement with the Company in any material respect;

then the Option, to the extent they have not been exercised, will automatically terminate and be forfeited upon the date of termination of employment or the date of such a finding. Any and all determinations of the Committee pursuant to this paragraph shall be final and binding on all persons; provided that such a determination may not be made arbitrarily.

6. If, at any time during or following Optionee’s employment with the Company, the Committee determines in its sole discretion, that Optionee has violated any of subparagraphs (a), (b), (c) or (d) below, the Option will automatically terminate and be forfeited upon that determination. Any and all determinations of the Committee pursuant to this paragraph shall be final and binding on all persons; provided that such a determination may not be made arbitrarily.

As a result, both during Optionee’s employment with the Company and thereafter, Optionee agrees, covenants and promises that Optionee will not, without the prior written consent of the Company, for any reason either directly or indirectly divulge to any third-party or use for Optionee’s own benefit, or for any purpose other than the exclusive benefit of the Company in accordance with Company policy, any Proprietary Information revealed, obtained or developed in the course of Optionee’s employment with the Company. If Optionee or any of Optionee’s representatives becomes legally compelled to disclose any of the Proprietary Information, Optionee will provide the Company with prompt written notice so that the Company may seek a protective order or other appropriate remedy.
