Long Term Compensation Program

 EXHIBIT 10.55 
  
 INTERDIGITAL COMMUNICATIONS CORPORATION 
 LONG TERM COMPENSATION PROGRAM 
  
 June 2004, as amended December 2004 
  
 The Company implemented the Long Term Compensation Program (the “Program”) to
encourage management and executive level employees to continue to exercise their best efforts toward ensuring the success of the Company. All regular full-time or regular part-time employees (as defined in the Employee Handbook) at or above a
manager or technical equivalent level are eligible to participate in the Program. 
  
 Compensation Components. As further described below, the Program consists of two compensation components: (1) a Long-Term Incentive Plan providing performance-based cash bonuses (the “LTIP”), and (2) an award of
restricted stock units (“RSUs”) under the Company’s 1999 Restricted Stock Plan. 
  
 The LTIP component of the Program rewards grantees based on the Company’s achievement of performance goals established/approved by the Compensation Committee of the Board of Directors (the “Compensation
Committee”). 
  
 The RSU awards provide recipients with an opportunity to
share in the growth of the Company’s value in the marketplace. An RSU is a contractual right to receive a share(s) of InterDigital Common Stock after completion of a specified vesting period. 
  
 Program Cycle. The Program operates in cycles (the “Program cycle”).
The first Program cycle began on April 1, 2004 and will end on December 31, 2005. Subsequent Program cycles are intended to be overlapping three-year cycles, beginning January 1, 2005 and recurring every other year thereafter. 
  
 LTIP Cash Bonuses. The LTIP cash bonus targets are established based on a
percentage of annual base salary and a payout under the LTIP is based on the Company’s achievement of certain performance goals associated with each Program cycle, established by the Compensation Committee at the start of each Program cycle.
Your cash LTIP payout may exceed or be less than your targeted amount depending on achievement of the performance goals, or no payout may be made if the Company fails to meet the minimum performance goals for the Program cycle. To be eligible for a
cash payout you must remain continuously employed by the Company (or an Affiliate of the Company) through the end of the Program cycle. For purposes of this Program, an Affiliate means any other individual, corporation, partnership, association,
trust or other entity that, directly or indirectly, is in control of or is controlled by or is under common control with the Company. Payout of the LTIP cash bonus will be made within the first quarter of the year following the end of each Program
cycle. 
  
 RSU Terms. RSUs will be granted under, and subject to the
terms of, the Company’s 1999 Restricted Stock Plan (the “Plan”). You will receive an RSU Award Agreement setting forth in detail the terms of your RSU grant along with a copy of the prospectus for the Plan. In the event of any
conflict between this summary and your RSU award agreement, the RSU award agreement will govern. 

 For all non-executives/officers, the RSUs granted in connection with each Program cycle will vest incrementally based on
the duration of the Program cycle. For the first cycle, vesting will occur over a two-year period with half of the RSUs vesting on December 31, 2004 and half vesting on December 31, 2005, so long as you remain continuously employed by the Company
(or an Affiliate) through the applicable vesting dates. For subsequent Program cycles, currently intended to be three years in duration, vesting will occur 25% at the end of years one and two, and 50% at the end of year three. For all
executive/officer level participants, the RSUs granted in connection with each Program cycle will vest 100% at the end of each cycle, so long as you remain employed by the Company or an Affiliate of the Company through the applicable vesting date.

  
 New Program Participants. If you are promoted to a level which
qualifies you to participate in the Program for the first time or you are newly hired within the first two years of a three-year Program cycle (or within the first year of a two-year cycle), you will be eligible to receive a pro rata LTIP cash bonus
and RSU award. The pro rata target LTIP cash bonus and RSU award will be determined based on the amount of time (number of pay periods) remaining in the LTCP cycle in which you are hired or promoted to a qualifying level. By way of example, if you
are a non-executive employee hired October 1st of the first year of a two year LTCP cycle, you would be eligible to
receive 3/12 of that year’s LTCP eligibility in addition to the full-year eligibility for the second year of the LTCP cycle. The LTIP (cash) and RSU awards will be paid out and vest respectively, as described under the sections entitled
“LTIP Cash Bonuses” and “RSU Terms”. 
  
 Promotion during Program Cycle. If you are promoted during a Program cycle and such promotion results in an accompanying increase in your Program payout target (LTIP target and RSU award), you will realize the benefit of the
Program target increase at the beginning of the next applicable Program cycle unless the Compensation Committee, in its sole discretion, authorizes such an adjustment at a different time. 
  
 Effect of Terminations. If, during a Program cycle, your employment with the Company terminates due to your death,
“disability,” “retirement,” or termination by the Company without “cause” (each as defined below), you will earn a pro-rata portion of your LTIP cash bonus and RSU award. That pro-rata portion will be determined by
multiplying both the amount of the LTIP cash bonus and the number of RSUs awarded to you under the Program by a fraction equal to the portion of the Program cycle that has transpired prior to the cessation of your employment over the entire Program
cycle. Such pro-rata payment and distribution will be made to you (or, if applicable, your estate) at the same time as bonus payments and share distributions are made to active employees participating in the Program. 
  
 If your employment ceases due to your termination for “cause” or for any reason
other than death, “disability”, “retirement” or a Terminating Event, all your rights under the Program (other than RSUs that have previously vested) will be forfeited. 
  
 For purposes of the Program: 
  

	 	•	 	“cause” means: (a) willful and repeated failure of an employee to perform substantially his or her duties (other than any such failure resulting from incapacity due to
physical or mental illness); (b) an employee’s conviction of, or plea of guilty or nolo contendere to, a felony which is materially and demonstrably injurious to the Company or an Affiliate; (c) willful misconduct or gross negligence by an
employee in connection with his or her employment; or (d) an employee’s breach of any material obligation or duty owed to the Company or an Affiliate. 

  

 -2- 

	 	•	 	“disability” means: (a) a disability entitling the employee to long-term disability benefits under the applicable long-term disability plan of the Company (or an Affiliate
if employee is employed by such Affiliate) ; or (b) if the employee is not covered by such a plan, a physical or mental condition or illness that renders the employee incapable of performing his or her duties for a total of 180 days or more during
any consecutive 12-month period. 

  

	 	•	 	“retirement” means resignation after attaining a combination of age plus years of service at the Company (and Affiliates) equal to 70. 

  
 Effect of a Terminating Event. If a Terminating Event (meaning a Change of
Control - as defined in the Plan - or liquidation of the Company) occurs during the Program cycle and while you are actively employed by the Company, then: 
  

	 	•	 	immediately prior to (but contingent on the occurrence of) that Terminating Event all your RSUs will become fully vested and you will receive a distribution of InterDigital shares
with respect to those RSUs; and 

  

	 	•	 	you will be entitled to an early payment of your LTIP cash bonus in an amount equal to the greater of (i) your target LTIP cash bonus, or (ii) the LTIP cash bonus that would have
been due to you at the end of the Program cycle (but for the Terminating Event), assuming performance through the remainder of the Program cycle would be consistent with performance in the portion of the Program cycle prior to the Terminating Event.
Payment of this amount will be made not later than 30 days after the Terminating Event. 

  
 Taxation of Awards. The following is a brief description of the federal income and employment tax treatment of Program awards. The rules governing these awards are complex and their application may vary
depending upon your individual circumstances. Moreover, statutory and regulatory provisions and their interpretations are subject to change. You are therefore encouraged to consult with your personal tax advisor regarding the tax consequences of
participation in the Program. 
  
 For federal income and employment tax purposes,
the full amount of any LTIP cash bonus will be taxable to you at the time the cash is paid to you. 
  
 For federal income tax purposes, you will recognize ordinary income with respect to the value of shares distributed in respect of RSUs at the time the shares are distributed to you based on the value of those shares
at that time. For employment tax and possibly state income tax purposes, you will be taxed on the value of the shares subject to your RSUs at the time those RSUs vest, based on the value of those shares at that time. Further information regarding
the taxation of your RSUs is contained in the Plan’s prospectus. 
  
 Future Program Cycles. While the Company reserves the right to alter or discontinue the Program at any time, its present intent is to continue the Program for future cycles. The 

  

 -3- 

 
Company expects future Program cycles to include both an LTIP component and an RSU component. If you are eligible to participate in a future Program cycle,
additional information will be distributed to you at the start of that cycle. 
  
 Administration. The Program is administered by the Compensation Committee. The Compensation Committee has the right to terminate or amend the Program and its components at any time for any reason. The Compensation
Committee also has the authority to select employees to receive awards, to create, amend, and rescind rules regarding the operation of the Program, to determine whether LTIP performance goals have been achieved, to reconcile inconsistencies, to
supply omissions and to otherwise make all determinations necessary or desirable for the operation of the Program. 
  
 No Assignment. You may not assign, pledge or otherwise transfer any right relating to a cash or RSU award under the Program and any attempt to do so will be
void. 
  
 No Right to Continued Employment. Your participation in
the Program does not gives you any right to continue in employment or limit in any way the right of the Company to terminate your employment at any time, for any reason. 
  
 Questions. If you have questions regarding the Program, please contact Gary Isaacs, Sr. Human Resources Officer, at
610-878-5721.

 INTERDIGITAL COMMUNICATIONS CORPORATION 
 LONG TERM COMPENSATION PROGRAM 
  
 SUPPLEMENTAL PROGRAM SUMMARY

  
 In addition to the Company’s Long Term Compensation Program (the
“Program”) Terms and Conditions as amended December 2004 (the “Terms and Conditions”), the provisions outlined in this Supplemental Program Summary apply to the Program. Taken together, the Terms and Conditions and this
supplemental document (along with the terms contained in the Company’s 1999 Restricted Stock Plan and associated prospectus (collectively, the “Plan”) as such terms relate to the grant of restricted stock units (“RSU”) made
under the Program), represents a comprehensive written description of the Program. 
  
 Program Goals 
  
  

	•	 	Introduces a new compensation program to attract, motivate and retain employees; and 

  

	•	 	Ensures alignment with market/industry practices and shareholder interests. 

  
 Program Cycles 
  
 As described in the Terms and Conditions, the initial Program cycle is a two-year cycle commencing April 1, 2004, with subsequent Program cycles occurring in overlapping
three-year cycles commencing January 1, 2005. Under the initial two-year Program cycle, all participants will receive two-thirds of a full three-year cycle. The opportunity for non-executive/officer-level participants as well as
executive/officer-level participants to receive the Long-Term Incentive Plan performance-based cash bonus component of the Program (“LTIP”) occurs at the end of each Program cycle. 
  
 Program Targets 
  
 The following Program targets are based on organizational levels (or a specific officer
position within the Company) and that organizational level’s (or the specific officer’s) base salary. The percentages are used to calculate the opportunity to receive the LTIP cash bonus component of the Program and the amount of the RSU
award component of the Program: 
  

			
	 •      Manager/Sr. Manager & Technical Equivalent – 40%
	 	 •      Chief Technology Officer – 90%

	 •      Director/Sr. Director & Technical Equivalent – 45%
	 	 •      Sr. Business Development Officer – 90%

	 •      Functional VP – 50%
	 	 •      General Counsel – 80%

	 •      Chief Executive Officer – 120%
	 	 •      Chief Strategic Standards Officer – 80%

	 •      Chief Operating Officer – 100%
	 	 •      Sr. Engineering & Programs Officer – 80%

	 •      General Patent Counsel – 100%
	 	 •      Sr. Human Resources Officer – 80%

	 •      Chief Financial Officer – 90%
	 	 •      Fellow, ASIC/DSP – 70%

  
 RSU awards are calculated based on the
target percentage of base salary of an eligible participant divided by the Company’s closing share price on the date of the RSU award (i.e., April 1, 2004 for the initial Program cycle).

Restricted Stock Units by a fraction equal to the portion of the Restricted Period that has transpired prior to such cessation of service or employment over the entire Restricted Period. Settlement for Restricted Stock Units that become vested
pursuant to this Section 4(c) will occur in accordance with Section 5 at the same time settlement would have occurred had Grantee remained employed through the end of the Restricted Period. 
  
 5. Settlement and Election to Defer Settlement. 
  
 (a) Restricted Stock Units credited hereunder (including Restricted Stock
Units credited in respect of Dividend Equivalents) will be settled by delivery of one share of the Company’s common stock for each Restricted Stock Unit being settled. Settlement will occur as soon as practicable following the applicable
Vesting Date, unless Grantee has elected to defer settlement in accordance with Section 5(b). 
  
 (b) By completing, signing and returning Exhibit “A” to this Agreement within thirty (30) days of this Agreement, Grantee may elect to defer the date of settlement of Restricted Stock Units credited
hereunder. If a Grantee elects to defer settlement, such deferred settlement must occur on or after             ,

 6. Dividend Equivalents and Adjustments. 
  
 (a) Dividend Equivalents shall be credited on Restricted Stock Units (other than Restricted Stock Units that, at the relevant record date, previously
have been settled or forfeited) in accordance with this Section 6: 
  
 (i) Cash Dividends. If the Company declares and pays a dividend or distribution on its Shares in the form of cash, then a number of additional Restricted Stock Units (rounded up or down to the nearest whole
number) shall be credited to Grantee’s Account as of the payment date for such dividend or distribution which number shall be equal to the number of Restricted Stock Units credited to the Account as of the record date for such dividend or
distribution multiplied by the amount of cash actually paid as a dividend or distribution on each outstanding Share at such payment date, divided by the Fair Market Value of a Share as of such payment date. 
  
 (ii) Non-Cash Dividends. If the Company declares and
pays a dividend or distribution on Shares in the form of property other than Shares or other shares of the Company, then a number of additional Restricted Stock Units shall be credited to Grantee’s Account as of the payment date for such
dividend or distribution 
  

 -3- 

 which number shall be equal to the number of Restricted Stock Units credited to the Account as of the
record date for such dividend or distribution multiplied by the fair market value of such property actually paid as a dividend or distribution on each outstanding Share at such payment date, divided by the Fair Market Value of a Share as of such
payment date. 
  
 (iii) Stock Dividends.
If the Company declares and pays a dividend or distribution on Shares in the form of additional Shares or other shares of the Company, then a number of additional Restricted Stock Units shall be credited to Grantee’s Account as of the payment
date for such dividend or distribution which number shall be equal to the number of Restricted Stock Units credited to the Account as of the record date for such dividend or distribution, multiplied by the number of additional Shares or other shares
of the Company actually paid as a dividend or distribution in respect of each outstanding Share. 
  
 7. Other Terms Relating to Restricted Stock Units. 
  
 (a) The number of Restricted Stock Units credited to a Grantee’s Account shall include fractional Restricted Stock Units calculated to at least
three decimal places, unless otherwise determined by the Committee. Upon settlement of Restricted Stock Units, Grantee shall be paid, in cash, an amount equal to the value of any fractional Share as of the Vesting Date that would have otherwise been
deliverable in settlement of such Restricted Stock Units. 
  
 (b)
It shall be a condition to the Company’s obligation to issue and deliver Shares in settlement of the Restricted Stock Units that Grantee (or the person to whom ownership rights may have passed by will or the laws of descent and distribution)
pay to the Company, upon its demand, such amount as may be required by the Company for the purpose of satisfying any liability to withhold federal, state, or local income or other taxes. If the amount required is not paid, the Company may refuse to
deliver the Shares in settlement of the Restricted Stock Units until such amount is paid. The Committee may, in its discretion, permit a Grantee (or the person to whom ownership rights may have passed by will or the laws of descent and distribution)
to pay all or a portion of the amount required by the Company for such tax withholding at such time and in such manner as the Committee shall deem to be appropriate, including by authorizing the Company to withhold from the Shares to be delivered in
settlement, or by agreeing to surrender to the Company on or about the date such tax liability is determinable, Shares having a Fair Market Value on such date equal to the amount of such tax liability or a specified portion of such tax liability.

  
 8. Absence of Tax Gross-Up Payment. There shall be no
tax gross-up on the Restricted Stock Units. 
  
 9. Notices.
Any notice to the Company under this Agreement shall be made in care of the Committee to the office of the General Counsel, at the Company’s main office in King of Prussia, Pennsylvania. All notices under this Agreement shall be deemed to have
been given when hand-delivered or mailed, first class postage prepaid, and shall be irrevocable once given. 
  

 -4- 

 10. Securities Laws. The Committee may from time to time impose any conditions on the Restricted
Stock Units (or the underlying Shares) as it deems necessary or advisable to comply with applicable securities laws. 
  
 11. Award Not to Affect Service. The Award granted hereunder shall not confer upon Grantee any right to continue service as an employee and/or
director of the Company. 
  
 12. Miscellaneous. 

 
 (a) The address for Grantee to which notice, demands and other
communications to be given or delivered under or by reason of the provisions hereof shall be the Grantee’s address as reflected in the Company’s personnel records. 
  
 (b) Grantee authorizes the Company to withhold in accordance with applicable law from any compensation payable to him/her
any taxes required to be withheld by federal, state or local law in connection with this award. 
  
 (c) Any provision for distribution in settlement of Grantee’s Account hereunder shall be by means of bookkeeping entries on the books of the Company
and shall not create in Grantee or any person to whom ownership rights may have passed any right to, or claim against any, specific assets of the Company, nor result in the creation of any trust or escrow account for Grantee or any person to whom
ownership rights may have passed. Grantee (or any other person entitled to a distribution hereunder) shall be a general creditor of the Company. 
  
 (d) The validity, performance, construction and effect of this Restricted Stock Unit Award shall be governed by the laws of the Commonwealth of
Pennsylvania, without giving effect to principles of conflicts of law. 
  
 IN WITNESS WHEREOF, the Company has caused this Restricted Stock Unit Award to be executed by its duly authorized officer, and Grantee has executed this Restricted Stock Unit Award, in each case as of the date first above written.

 (a)
Subject to the terms and conditions set forth herein and in the Plan, the Company hereby grants to Grantee the Restricted Stock Units. The Company shall maintain an Account for Grantee reflecting the number of Restricted Stock Units credited to
Grantee hereunder. 
  
 (b) All of the terms, conditions and other
provisions of the Plan are hereby incorporated by reference into this Agreement. Capitalized terms used in this Agreement but not defined herein shall have the same meanings as in the Plan. If there is any conflict between the provisions of this
Agreement and the provisions of the Plan, the provisions of the Plan shall govern. Grantee acknowledges receipt of the Plan, a copy of which is annexed hereto, represents that he/she is familiar with the terms and provisions thereof and hereby
agrees to be bound by the Plan (as presently in effect or hereafter amended) and this Agreement, and by all decisions and determinations of the Committee thereunder. (For purposes of this provision and other provisions of this Agreement, references
to the Committee include any persons or administrative body to whom the Committee has delegated authority.) 
  
 3. Restrictions on Restricted Stock Units. Subject to the terms and conditions set forth herein and in the Plan, Grantee shall not be permitted to
sell, transfer, pledge or assign the Restricted Stock Units except by will or by the laws of descent and distribution. No such transfer occurring as a result of the Grantee’s death shall be effective to bind the Company unless the Company shall
have been furnished with a copy of the applicable will or such other evidence as the Company may deem necessary to establish the validity of the transfer. 
  
 4. Vesting and Forfeiture. 
  
 (a) Except as otherwise provided in this Section 4, Restricted Stock Units granted hereunder shall vest (meaning that the risk of forfeiture of such
Restricted Stock Units shall lapse) on the Vesting Date if Grantee remains continuously employed by the Company or one of its Affiliates through that date. Each Restricted Stock Unit credited under Section 6 in respect of Dividend Equivalents shall
vest at the time of vesting of the Restricted Stock Unit that gives rise, directly or indirectly, to such Dividend Equivalent. 
  
 (b) If Grantee’s service as an employee of the Company or one of its Affiliates ends prior to the Vesting Date due to a termination for Cause, or
termination of employment for any reason other than death, Disability, Retirement or Terminating Event, all Restricted Stock Units granted hereunder will be forfeited. 
  
 (c) If Grantee’s service or employment with the Company or an Affiliate ceases prior to the Vesting Date due to death,
Disability, Retirement, or termination by the Company without Cause, Grantee will become vested in a pro-rata portion of his or her Restricted Stock Units. That pro-rata portion will be determined by multiplying the number of 
  

 -2- 

 Restricted Stock Units by a fraction equal to the portion of the Restricted Period that has transpired prior to such
cessation of service or employment over the entire Restricted Period. Settlement for Restricted Stock Units that become vested pursuant to this Section 4(c) will occur in accordance with Section 5 at the same time settlement would have occurred had
Grantee remained employed through the end of the Restricted Period. 
  
 5. Settlement and Election to Defer Settlement. 
  
 (a) Restricted Stock Units credited hereunder (including Restricted Stock Units credited in respect of Dividend Equivalents) will be settled by delivery of one share of the Company’s common stock for each Restricted Stock Unit being
settled. Settlement will occur as soon as practicable following the applicable Vesting Date, unless Grantee has elected to defer settlement in accordance with Section 5(b). 
  
 (b) By completing, signing and returning Exhibit “A” to this Agreement within thirty (30) days of this Agreement,
Grantee may elect to defer the date of settlement of Restricted Stock Units credited hereunder. If a Grantee elects to defer settlement, such deferred settlement must occur on or after
                    ,                 . 
  
 6. Dividend Equivalents and Adjustments. 
  
 (a) Dividend Equivalents shall be credited on Restricted Stock Units (other
than Restricted Stock Units that, at the relevant record date, previously have been settled or forfeited) in accordance with this Section 6: 
  
 (i) Cash Dividends. If the Company declares and pays a dividend or distribution on its Shares in the form of cash, then a number
of additional Restricted Stock Units (rounded up or down to the nearest whole number) shall be credited to Grantee’s Account as of the payment date for such dividend or distribution which number shall be equal to the number of Restricted Stock
Units credited to the Account as of the record date for such dividend or distribution multiplied by the amount of cash actually paid as a dividend or distribution on each outstanding Share at such payment date, divided by the Fair Market Value of a
Share as of such payment date. 
  
 (ii)
Non-Cash Dividends. If the Company declares and pays a dividend or distribution on Shares in the form of property other than Shares or other shares of the Company, then a number of additional Restricted Stock Units shall be credited to
Grantee’s Account as of the payment date for such dividend or distribution which number shall be equal to the number of Restricted Stock Units credited to the Account as of the record date for such dividend or distribution multiplied by the
fair market value of such property actually paid as a dividend or distribution on each outstanding Share at such payment date, divided by the Fair Market Value of a Share as of such payment date. 
  
 (iii) Stock Dividends. If the Company declares and
pays a dividend or distribution on Shares in the form of additional Shares or other shares of the 
  

 -3- 

 Company, then a number of additional Restricted Stock Units shall be credited to Grantee’s Account
as of the payment date for such dividend or distribution which number shall be equal to the number of Restricted Stock Units credited to the Account as of the record date for such dividend or distribution, multiplied by the number of additional
Shares or other shares of the Company actually paid as a dividend or distribution in respect of each outstanding Share. 
  
 7. Other Terms Relating to Restricted Stock Units. 
  
 (a) The number of Restricted Stock Units credited to a Grantee’s Account shall include fractional Restricted Stock Units calculated to at least
three decimal places, unless otherwise determined by the Committee. Upon settlement of Restricted Stock Units, Grantee shall be paid, in cash, an amount equal to the value of any fractional Share as of the Vesting Date that would have otherwise been
deliverable in settlement of such Restricted Stock Units. 
  
 (b)
It shall be a condition to the Company’s obligation to issue and deliver Shares in settlement of the Restricted Stock Units that Grantee (or the person to whom ownership rights may have passed by will or the laws of descent and distribution)
pay to the Company, upon its demand, such amount as may be required by the Company for the purpose of satisfying any liability to withhold federal, state, or local income or other taxes. If the amount required is not paid, the Company may refuse to
deliver the Shares in settlement of the Restricted Stock Units until such amount is paid. The Committee may, in its discretion, permit a Grantee (or the person to whom ownership rights may have passed by will or the laws of descent and distribution)
to pay all or a portion of the amount required by the Company for such tax withholding at such time and in such manner as the Committee shall deem to be appropriate, including by authorizing the Company to withhold from the Shares to be delivered in
settlement, or by agreeing to surrender to the Company on or about the date such tax liability is determinable, Shares having a Fair Market Value on such date equal to the amount of such tax liability or a specified portion of such tax liability.

  
 8. Absence of Tax Gross-Up Payment. There shall be no
tax gross-up on the Restricted Stock Units. 
  
 9. Notices.
Any notice to the Company under this Agreement shall be made in care of the Committee to the office of the General Counsel, at the Company’s main office in King of Prussia, Pennsylvania. All notices under this Agreement shall be deemed to have
been given when hand-delivered or mailed, first class postage prepaid, and shall be irrevocable once given. 
  
 10. Securities Laws. The Committee may from time to time impose any conditions on the Restricted Stock Units (or the underlying Shares) as it deems
necessary or advisable to comply with applicable securities laws. 
  

 -4- 

 11. Award Not to Affect Service. The Award granted hereunder shall not confer upon Grantee any
right to continue service as an employee and/or director of the Company. 
  
 12. Miscellaneous. 
  
 (a) The address for Grantee to which notice, demands and other communications to be given or delivered under or by reason of the provisions hereof shall be the Grantee’s address as reflected in the Company’s personnel records.

  
 (b) Grantee authorizes the Company to withhold in accordance
with applicable law from any compensation payable to him/her any taxes required to be withheld by federal, state or local law in connection with this award. 
  
 (c) Any provision for distribution in settlement of Grantee’s Account hereunder shall be by means of bookkeeping entries on the books of the Company
and shall not create in Grantee or any person to whom ownership rights may have passed any right to, or claim against any, specific assets of the Company, nor result in the creation of any trust or escrow account for Grantee or any person to whom
ownership rights may have passed. Grantee (or any other person entitled to a distribution hereunder) shall be a general creditor of the Company. 
  
 (d) The validity, performance, construction and effect of this Restricted Stock Unit Award shall be governed by the laws of the Commonwealth of
Pennsylvania, without giving effect to principles of conflicts of law. 
  
 IN WITNESS WHEREOF, the Company has caused this Restricted Stock Unit Award to be executed by its duly authorized officer, and Grantee has executed this Restricted Stock Unit Award, in each case as of the date first above written.

(for which Licensee shall be solely responsible). Invoices shall not include any taxes, impositions, charges or exactions for which Licensee has furnished a valid exemption certificate. 
  
 5    Commercial Off-the-Shelf (COTS)/Open Source Software Limitations 
  
 Licensor shall not use commercial proprietary software or hardware as an integral part of
the software delivered under this Agreement unless Licensor has obtained the rights in third party commercial proprietary software or hardware at least equal to those granted by Licensor to Licensee. 
  
 Deliverable items involving COTS hardware or software will, in general, utilize the
“then current” commercially available versions of those COTS items at the time that Licensed Software is delivered. 
  
 Licensee shall not obtain or use COTS or Open Source items, if usage of such items by Licensee, or its customer, and the U. S. Government is restricted in any way, or if
such items require any licensing of rights, without prior written Licensee approval and direction. 
  
 6    Proprietary Information 
  
 The parties anticipate that during the term of this Agreement, it may be necessary for either party to transfer to the other party information of a proprietary nature. Each of the parties agrees that it will use the
same reasonable efforts to protect the other’s Proprietary Information as are used to protect its own but will at least use reasonable care. Disclosures of such information shall be restricted to those individuals who are directly participating
in the JTRS or the MUOS programs and contract efforts identified herein, who have a need to know such information, and who have been made aware of and consent to abide by the restrictions herein concerning the use of such information. 
  
 Neither party shall make any reproduction, disclosure, nor use of such Proprietary
Information except as may be required in the performance of this Agreement. 
  
 The obligation to protect Proprietary Information, and the liability for unauthorized disclosure or use of Proprietary Information, shall not apply with respect to such information which is now available or becomes available to the public
without breach of this Agreement; information lawfully received without restrictions from other sources, including the U.S. Government; information known to the Receiving Party prior to disclosure; information published or disclosed by the
Disclosing Party to others, including the U.S. Government, without restriction; information developed by the Receiving Party independent of and without use of the information disclosed by the Disclosing Party; or, information for which further use
or disclosure by the Receiving Party is authorized in writing by the Disclosing Party. 
  

 10 

 The obligations and provisions of this provision shall survive the expiration and termination of the other portions of
this Agreement for a period of [**] from the date hereof. Upon termination or expiration of this Agreement each party will, upon request, return all Proprietary Information received from the other party and copies made thereof by the Receiving Party
under this Agreement, or certify by written memorandum that all such Proprietary Information has been destroyed except that each party may retain an archival copy to be used only in case of a dispute concerning this Agreement. 
  
 Each party warrants that it has the right to disclose the Proprietary Information disclosed
to the other party hereunder for the purpose set out in this Agreement. 
  
 Except
as expressly provided herein neither the execution and delivery of this Agreement, nor the furnishing of any Proprietary Information shall be construed as granting either expressly or by implication, estoppel or otherwise, any license under any
invention, improvement, discovery or patent now or hereafter owned or controlled by a party disclosing Proprietary Information hereunder. 
  
 If either Party should be required by law or regulation, or receive a subpoena, court order or other governmental order that compels such Party to disclose Proprietary
Information of the other Party, it shall promptly notify the Disclosing Party so the latter may take necessary steps to prevent or limit disclosure. In any event, the Receiving Party shall disclose only so much of the Disclosing Party’s
Proprietary Information as is required by law. 
  
 7    Limitations on Usage of Licensee Furnished Items 
  
 Licensee furnished items are defined to be any software, firmware, hardware, systems, or documentation, provided by Licensee to Licensor. Licensor shall not reverse engineer Licensee furnished items. Upon completion
of the effort under the attached SOW, or upon request by Licensee, whichever occurs first, the Licensor shall return all Licensee furnished items to Licensee, unless otherwise specified by Licensee in writing or in the requirements of the SOW.

  
 8    Quality Assurance/Configuration
Management/Safety Requirements 
  
 Licensor shall establish and maintain
a quality assurance system that complies with its standard commercial processes with the intent of meeting ISO 9001 and other applicable industry standards that Licensor has adopted as part of its quality program. Licensor will allow Licensee
representative(s) to witness testing at Licensor’s facility for any software that will be delivered to Licensee as part of a Milestone described within this Agreement. 
  
 Subsequent to Agreement Effective Date, Quality and Configuration Management plans will be generated (either as a stand alone or
incorporated within other plans). The resulting quality or configuration management plan will clearly describe the technical change review board process that will be conducted between Licensor and Licensee. 
  
 Licensee may require Licensor to provide data and perform analysis in support of MUOS program
safety requirements that may be subsequently required under this Agreement after the Effective Date. Any resulting safety requirements will be negotiated in good faith and accepted in writing by the Parties, but will be included within the scope of
this Agreement.

 9    Malicious Software or Systems 
  
 The Licensor shall determine that, to the best of its knowledge and belief, the software and
systems provided do not contain any malicious code, program, or other internal component (e.g., computer virus) which could damage, destroy, or alter software, firmware, or hardware or which could reveal any data or other information accessed
through or processed by the software or systems. Further, the Licensor shall immediately inform Licensee upon reasonable suspicion that any software or systems provided hereunder may cause the harm described above. 
  
 10    Force Majeure 
  
 A Party shall be excused for nonperformance under this Agreement, for such period of time as
the cause of non-performance continues to exist, if the failure to perform arises, in whole or in part, out of causes beyond the control and without the negligence of the Party. Such causes may include, but are not restricted to (a) acts of God or
of the public enemy, (b) acts of the Government in either its sovereign or contractual capacity, (c) fires, (d) floods, (e) epidemics, (f) quarantine restrictions, (g) strikes, (h) freight embargoes and (i) unusually severe weather. If the delay is
caused by a delay of Licensor and if such delay arises out of causes beyond the reasonable control of both, and without the negligence of either, Licensor shall be excused from nonperformance unless the goods to be furnished by the Licensor were
obtainable from other sources at substantially the same cost in sufficient time to permit Licensor to meet the required delivery schedules. Licensor shall notify Licensee in writing within ten (10) calendar days after the beginning of any such
cause. 
  
 11    Governing Law and Venue

  
 This Agreement shall be governed by and construed in accordance with the
laws of the State of Delaware. No consideration shall be given to Delaware’s conflict of laws rules. To the extent not provided for in Section 12, the Parties agree and consent to exclusive venue and jurisdiction in the state and federal courts
located in Delaware for all controversies and disputes arising under or in any way relating to this Agreement. 
  
 12    Disputes 
  
 (a)    Any dispute between the Parties shall be settled in the following manner: Licensee and Licensor agree to enter into a negotiation to resolve any dispute. Both parties agree to negotiate in good faith to reach a
mutually agreeable settlement within a reasonable amount of time. Each Party will appoint a senior management representative who does not devote substantially all of his or her time to performance under this Agreement. The representatives will
furnish to each other all non-privileged information with respect to the dispute that the Parties believe to be appropriate and germane. The representatives will negotiate in an effort to resolve the dispute without the necessity of any formal
proceeding. [**] 
  
 (b)    [**] Either Party will have the
right to apply at any time to a judicial authority for appropriate injunctive or other interim or provisional relief [**] 
  

 ** Material has been omitted and filed separately with the Commission. 
  

 12 

 13    Injunctive Relief 
  
 The Parties agree to the confidentiality provisions contained in Section 6, above, and acknowledge that the unauthorized disclosure of any
information required to be kept confidential pursuant to this Agreement may give rise to immediate irreparable injury to the Party that owns the information. Notwithstanding the dispute resolution provision contained herein, each Party may obtain
immediate and injunctive relief against the breach or threatened breach by the other Party of the covenants to keep such information confidential. The Parties further agree that the covenants contained herein are reasonably necessary for the
protection of legitimate business interests of the Parties and are reasonable in scope and content. 
  
 14    Severability 
  
 In the event that any provision of this Agreement shall be unenforceable or invalid under any applicable law or be so held by applicable court decision, such unenforceability or invalidity shall not render this Agreement unenforceable or
invalid as a whole, and, in such event, such provision shall be changed and interpreted so as to best accomplish the objectives of such unenforceable or invalid provision within the limits of applicable law or applicable court decisions. 

 
 15    Export/Security Regulations 
  
 Licensee agrees that it will not in any form export, re-export, ship, or divert or cause to
be diverted, directly or indirectly, the Licensed Software to any country for which the United States Government, any agency thereof, or any other sovereign Government, at the time of export or reexport, requires an export license or other
governmental approval without first obtaining such license or approval. Furthermore, Licensor understands that the majority of MUOS Technical Information and Technical Services are subject to U.S. Government export control laws and regulations.
Therefore, Licensor shall be responsible for compliance with all applicable U.S. export control laws and regulations including the requirements of the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR).
Licensor agrees that, except as allowed under applicable U.S. laws and regulations, no export controlled item, data, or service, furnished to it on or produced by it for the MUOS Program will be disclosed to any foreign person, business, or country,
including foreign persons employed by or associated with, or under contract with the Licensor, without the authority of an export license, agreement or applicable license exemption. In the event the Licensor or any sub tier supplier needs to
disclose MUOS export-controlled items, data or services to foreign persons, the Licensor shall be responsible (i) for obtaining, and ensuring its sub tier supplier obtains, all necessary approvals from the Government and any required export license,
agreement or applicable license exemption and (ii) for compliance with the terms of the export license, agreement or exemption. Licensor shall first notify and obtain the written consent of Licensee prior to it or its sub tier supplier submitting
any request for authority to export MUOS technical data or services. Licensor is responsible for including export control requirements in sub tier supplier agreements, and for ensuring that the suppliers are capable of complying with all applicable
U.S. Government export control laws and regulations. 
  
 Licensor is responsible
for maintaining an effective export/import compliance program that ensures compliance to government export control laws and regulations. Licensor is responsible for maintenance of proper policies and procedures, personnel training, and marking of
documents, as appropriate, in accordance with such export/import compliance program. 
  
 If required by Licensee, Licensor agrees to implement security requirements mandated by the U.S. Government issued via a DD-254 to Lockheed Martin’s contract and subsequently flowed down to 

  

 13 

 
Licensee’s contract. If Licensor is unable to implement or follow such requirements, the Parties will negotiate in good faith to resolve such issue or
issues. 
  
 16    Records, Audit Rights

  
 At all times during the term of this Agreement and for [**] following the
termination of this Agreement, Licensee will maintain at its principal place of business accurate records relating to its licensing obligations under this Agreement. 
  
 17    Point of Contact Designation 
  
 The Licensor shall designate to Licensee, in writing, a representative to serve as point of contact for the Licensor with Licensee or the
Government. 
  
 18    Guidelines on Nationality

  
 Licensor further understands that Licensee is a defense contractor
providing work for the United States Government, and as such, is under certain mandatory security obligations with regard to access to its facilities and technology. Due to the fact that disclosure of certain information to any individual may be
deemed an export, Licensor agrees that it will not assign any worker to perform services under this Agreement on Licensee’s premises for the applicable program unless that person either receives a license for the export at issue or qualifies as
a “U.S. person.” The following persons shall be defined as a “U. S. person”: 
  

	 	i.	U.S. citizen; 

  

	 	ii.	U.S. nationals, including an alien lawfully admitted for permanent residence (those possessing a valid Form I-550 or “green card”); 

  

	 	iii.	Alien admitted following a 1986 amnesty statute; 

  

	 	iv.	Asylee or refugee as defined in 8 U.S.C. 1324(b)(a)(3); or 

  

	 	v.	Alien lawfully admitted for temporary agricultural employment. 

  
 18.1    Access to Information 
  
 Licensor further agrees that, should Licensee determine that the work performed under this Agreement will enable persons working for the Licensor (including the Licensor)
to have access to unclassified information that relates to a U.S. Government classified program, or other information regulated by the National Industrial Security Program Operating Manual (‘NISPOM”), Licensor will not assign any worker to
perform services under this Agreement (including the Licensor) unless such persons are citizens or nationals of the United States. 
  
 In addition to the foregoing requirements, Licensor will comply with the Immigration Reform and Control Act of 1986 (“IRCA”) and in particular, have all of its
applicable workers fill out an I-9 form, verifying their authorization to work in the United States. 
  

 ** Material has been omitted and filed separately with the Commission. 
  

 14 

 Licensee agrees to conspicuously mark all documentation and technical information that is subject to a U.S. Government
classified program (including NISPOM). Licensee further agrees to use its best efforts to assist Licensor from time to time, upon request, to determine the appropriate export control classification of particular documentation and technical
information (e.g., whether subject to ITAR or EAR, and USML Category or Export Control Classification No.). Furthermore, Licensee represents and warrants to Licensor that all persons assigned by Licensee to communicate with Licensor in
connection with this Agreement are “U.S. persons” as defined in Section 18 above. 
  
 19    Gratuities 
  
 Licensor warrants that neither it nor any of its employees, agents or representatives have offered or given, or will offer or give, any gratuities to Licensee’s employees, agents or representatives for the purpose of securing this
Agreement or securing favorable treatment under this Agreement. 
  
 20    Publicity 
  
 Except as required
by law or applicable regulation (including without limitation, SEC and Nasdaq rules), neither Party shall issue any press release or make any other public statement or filing relating to this Agreement, any work done under this Agreement or any of
the transactions contemplated by this Agreement without obtaining the prior written approval of the other party (which approval shall not be unreasonably withheld) as to the contents and the manner of presentation and publication of such press
release or public statement. 
  
 21    [**]

  
 22    Waiver 
  
 The failure of either Party to require performance by the other party of any provision
hereof shall not affect the full right to require such performance at any time thereafter; nor shall the waiver by either Party of a breach of any provision hereof or failure to enforce a right hereunder be taken or held to be a waiver of the
provision itself. No delay or omission by either Party to this Agreement in the exercise or enforcement of any of its powers or rights hereunder shall constitute a waiver of such power or right. A waiver by either Party of any provision of this
Agreement must be in writing and signed by such Party, and shall not imply subsequent waiver of that or any other provision. 
  
 23    Nature of Relationship 
  
 Nothing contained herein shall be construed as Licensee and Licensor creating a joint venture, agency, employment relationship, partnership, principal-agent, joint
development or other form of joint enterprise between the Parties. Neither Party shall be liable to any person for any debts, liabilities or obligations incurred by or on behalf of the other Party hereto or its business. Both Parties agree to
disclose in their respective dealings that they are separate entities. 
  

 ** Material has been omitted and filed separately with the Commission. 
  

 15 

 24    Non-Solicitation 
  
 During the term of this Agreement and for [**] after its expiration or termination, neither Party will solicit for employment any employee
of the other Party who was involved in the performance of the Party’s obligations under this Agreement, unless the hiring party first obtains the written consent of the other party. Notwithstanding the foregoing, either Party shall have the
right to hire any individual employed by the other who, without solicitation, responds to employment advertising in the newspapers, trade publications or other public commercial media or any unsolicited walk in candidates not related to this
Agreement. 
  
 25    Notices 
  
 Wherever under this Agreement one Party is required or permitted to give notice to the
other, such notice shall be in writing and shall be effected either by personal delivery or [**] after deposit in the United States mail, registered or certified, postage prepaid, return receipt requested, to the receiving Party’s respective
address shown on the first page hereof, or via telefacsimile with confirmation receipt followed by U.S. mail. Each Party to this Agreement may from time to time change the address to which notices may be given by giving the other Party written
notice, in the manner provided in this Section, of the new address and the date upon which it will become effective. 
  
 The primary points of contact for the transmittal of Proprietary Information, notices, and authorizations under this Agreement are as follows: 
  
 InterDigital Communications Corporation 
 [**], Senior Manager 
  
 and 
  
 Decision Systems 
 [**], Staff Contract
Manager 
  
 Either Party may redesignate its respective designated
representative(s) by written or electronic notice to the other Party. 
  
 26    Attorneys’ Fees 
  
 In the
event there is any proceeding or lawsuit in connection with this Agreement, the prevailing party in such proceeding shall be entitled to receive its costs, expert witness fees and reasonable attorneys’ fees, including costs and fees on appeal.

  
 27    Bankruptcy of InterDigital 

 
 The Agreement is to be interpreted in accordance with Section 365(n) of the U.S.
Bankruptcy Code. It is understood and agreed that the intellectual property license under this Agreement is intellectual property as defined in Section 101(35A) of the Bankruptcy Code and that Section 365(n) shall govern this Agreement in the event
that InterDigital files for bankruptcy.

 28    Government Contracts Flowdown Clauses 
  
 Licensor agrees to comply with any applicable provisions of the Rehabilitation Act of 1973,
the Veteran’s Readjustment Act of 1974, and Executive Order 11246, and implementing regulations of the U.S. Department of Labor, which embody governmental policy on equal employment opportunity. The following FAR provisions are incorporated

 Exhibit A – Delivery/Payment Schedule 
 Exhibit B – Statement of Work 
 Exhibit C – Software Maintenance,
Support and Training 
  
 30    Entire Agreement

  
 To the extent Licensee is licensed under a patent license agreement (or
any agreement providing for the license of patent rights) with Licensor or any of its subsidiaries, which patent license covers the manufacture, sale or use of (1) commercial products, (2) or products under standards that differ from the standards
covered under this Agreement, or (3) other products that differ from the products covered under this Agreement, such other patent license agreement shall remain in full force and effect both as to the commercial products and as to those differing
standards and/or other products. To the extent Licensee was licensed under another patent license agreement with Licensor or any of its subsidiaries prior to the Effective Date for the manufacture, use, or sale of FDD products covered under this
Agreement, the terms of that prior agreement shall continue to apply up to but not including the Effective Date. With the exception of the foregoing and the treatment of confidential information disclosed pursuant to the Non-Disclosure Agreement
dated June 9, 2003, this Agreement contains the complete and final agreement between the Parties, and supersedes all previous understandings, relating to the subject matter hereof whether oral or written. This Agreement may only be modified or
amended by a written agreement signed by duly authorized representatives of each Party. 
  
 31    Order of Precedence 
  
 In the
event that two or more provisions in this Agreement conflict and there is no reasonable interpretation that resolves the conflict in a manner that is consistent with the entire Agreement, then the Parties shall resolve the conflict using the
following descending order of precedence: 1) this Software License Agreement; and 2) the Attachments hereto. 
  
 32    Changes 
  
 If a change order causes an increase or decrease in the cost of, or time required for the performance of this Agreement an equitable adjustment shall be made in the price or delivery schedule, or both, and the Agreement shall be modified,
in writing, accordingly. Failure to agree to any adjustment shall be a dispute to be resolved under the procedures established in this Agreement.

 33    Assignment 
  
 Licensor recognizes that General Dynamics Decision Systems will be renamed General Dynamics C4 Systems (“C4 Systems”) in early
2005 due to an internal reorganization. InterDigital consents to an assignment of this agreement to C4 Systems at the time the reorganization occurs provided that C4 Systems assumes all rights, obligations and responsibilities of General Dynamics
Decision Systems with respect to this Agreement and all rights, obligations and responsibilities of General Dynamics Decision Systems’ role in the MUOS Project at the Effective Date of this Agreement. Further, should General Dynamics Decision
Systems remain in existence as a legal entity following such reorganization, it shall remain contingently liable for all of C4 System’s assigned obligations and responsibilities hereunder. Licensor shall be notified by General Dynamics Decision
Systems when such name change occurs. Licensor may not assign or transfer this Agreement to another party unless Licensee agrees to such assignment or transfer and such consent shall not be unreasonably withheld.
