C. Tax Gross Up. In the event any amount or benefit payable to the Employee under this Agreement or under any other plan, agreement or arrangement applicable to the Employee, is subject to an excise tax imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code") (or imposed under any successor provision of the Code imposing a tax liability on "excess parachute payments" as that term is defined in Code Section 280G), Employee shall be entitled, in addition to any other amounts payable under the terms of this Agreement or under any other plan, agreement or arrangement applicable to the Employee, to a cash payment in an amount sufficient to indemnify the Employee (or such other person as may be liable for the payment of such excise tax) for the amount of any such excise tax, and leaving Employee with an amount, net after all federal, state and local taxes, equal to the amount Employee would have had if no portion of his benefit under the Plan constituted an "excess parachute payment". Notwithstanding the foregoing, the determination of the amount necessary to indemnify the Employee shall be made taking into account all other payments made to the Employee under any plans, agreements or arrangements aside from this Agreement that are intended to indemnify the Employee with respect to excise taxes on "excess parachute payments." Any disputes as to calculations to be made under this paragraph shall be resolved by the Company's independent auditors, whose determinations shall be final and binding. D. Nonqualified Deferred Compensation. If any payment to Executive under the terms of this Agreement is determined to constitute a payment of nonqualified deferred compensation for purposes of Section 409A of the Code, such payment shall be delayed until the date that is six months after the date of Executive's separation from service with the Company, so as to comply with the special rule for certain "specified employees" set forth in Code Section 409A(a)(2)(B)(i) unless it is determined that immediate distribution is permissible (and does not trigger any additional tax liability pursuant to Code Section 409A(a)(l)) pursuant to Code Section 409A(a)(2)(A)(v) by reason of being payable in connection with a change in the ownership or effective control of the Company or in the ownership of a substantial portion of the assets of the Company or is otherwise determined not to be subject to such additional tax liability. 6. Confidentiality. Employee recognizes and acknowledges that the Proprietary Information (as hereinafter defined) is a valuable, special and unique asset of the Business of the Company. As a result, both during the Term and thereafter, Employee shall not, without the prior written consent of the Company, for any reason either directly or indirectly divulge to any third party or use for his own benefit, or for any purpose other than the exclusive benefit of the Company, any confidential, proprietary, business and technical information or trade secrets of the Company or of any subsidiary or affiliate of the Company ("Proprietary Information") revealed, obtained or developed in the course of his employment with the Company.

Failure by the Company to mark any of the Proprietary Information as confidential or proprietary shall not affect its status as Proprietary Information under the terms of this Agreement.

In case any one or more of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the validity of any other provision of this Agreement, and such provision(s) shall be deemed modified to the extent necessary to make it enforceable. 20.

Specific Enforcement; Extension of Period. A. Employee acknowledges that the restrictions contained in Sections 6, 7, and 8 hereof survive the termination of his employment, regardless of the reason, are reasonable and necessary to protect the legitimate interests of the Company and its subsidiaries and affiliates and that the Company would not have entered into this Agreement in the absence of such restrictions. Employee also acknowledges that any breach by him of Sections 6, 7, and 8 hereof will cause continuing and irreparable injury to the Company for which monetary damages would not be an adequate remedy. The Employee shall not, in any action or proceeding to enforce any of the provisions of this Agreement, assert the claim or defense that an adequate remedy at law exists. In the event of such breach by Employee, the Company shall have the right to enforce the provisions of Sections 6, 7, and 8 of this Agreement by seeking injunctive or other relief in any court, and this Agreement shall not in any way limit remedies of law or in equity otherwise available to the Company. If an action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to recover, in addition to any other relief, reasonable attorneys' fees, costs and disbursements. In the event that the provisions of Sections 6, 7, and 8 hereof should ever be adjudicated to exceed the time, geographic, or other limitations permitted by applicable law in any applicable jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the maximum time, geographic, or other limitations permitted by applicable law. B. In the event that Employee shall be in breach of any of the restrictions contained in Section 8 hereof, then the Restricted Period shall be extended for a period of time equal to that period of time that Employee is in breach of such restriction. The Company agrees to notify Employee as soon as practicable following a determination that Employee is in breach of any restriction contained in Section 8. 13 C. In the event that Employee shall be in breach of any of the restrictions contained in Sections 6, 7 or 8 hereof, Employee shall forfeit his right to any further payments pursuant to Section 9 (without limiting any other relief to which the Company may be entitled), but the release in the termination letter as described in Section 10 will remain in full force and effect. 23. Consent to Suit. Any legal proceeding arising out of or relating to this Agreement shall be instituted in the District Court of the Eastern District of Pennsylvania, or if such court does not have jurisdiction or will not accept jurisdiction, in any court of general jurisdiction in the Commonwealth of Pennsylvania, and the Employee hereby consents to the personal and exclusive jurisdiction of such court and hereby waives any objection that the Employee may have to the laying of venue of any such proceeding and any claim or defense of inconvenient forum. 24. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, and all of which together shall be deemed to be one and the same instrument. IN WITNESS WHEREOF, the parties have caused this Agreement to be executed the day and year first written above. ATTEST: INTERDIGITAL COMMUNICATIONS CORPORATION /s/ Lisa Axt Alexander /s/ William J.
