Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General ------- The Plan is a defined contribution 401(k) plan of InterDigital Communications Corporation and its participating subsidiaries (the "Company") for eligible employees over the age of 18 and who have completed one month of service. Beginning in 2004, individuals employed by the Company as part of an academic course of study, such as a work-study program, co-op program or similar arrangements, are not eligible. The Plan was established effective February 1, 1985 and restated January 1, 1997. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). Reliance Trust Company is the trustee of the Plan. Contributions ------------- All participant contributions are made on a before-tax basis. In 2003 each participant could invest from 1% to 15% of annual compensation as a basic contribution, beginning 2004 each participant may invest from 1% to 100% of annual compensation as a basic contribution. The total of the basic and supplemental contributions cannot exceed IRS limitations for each plan year. For the 2004 and 2003 plan years, the total IRS limitations were $13,000 and $12,000, respectively. If a participant's annual contributions exceed the dollar limitation set by the IRS, thereby requiring a distribution of such excess contributions, the participant will forfeit any employer matching contributions related to the distribution amount. Amounts forfeited will be used to reduce future employer contributions. The Company may, at its sole discretion, contribute to the Plan through matching contributions and/or discretionary contributions. Beginning July 2001, the Company matches 50% of each participant's contribution, up to a maximum of 6% of the participant's pretax annual basic compensation, as defined by the plan. During 2003, 50% of the Company match consisted of cash and the other 50% was directed by the Company to the InterDigital Stock Fund. Beginning in 2004, the Company match is directed by the Company to the InterDigital Stock Fund and may be immediately transferred to other investment alternatives by Plan participants. Discretionary contributions are lump sum payments made to the Plan as determined from time to time by the Board of Directors of the Company. In first quarter 2005, the Company contributed 32,632 shares of InterDigital Common Stock, valued at $567,808, to participant accounts in association with the Company's performance in 2004. The Plan recorded a related receivable at December 31, 2004. The Company did not make any discretionary contributions in 2003. The Internal Revenue Code limits the amount of pay that may be used to determine contributions. The limit was $205,000 and $200,000 in 2004 and 2003, respectively. The law also limits the amount of all contributions that can be made for or by a participant to the Plan in a given year. The limit is the lesser of 100% of pay or $41,000 for 2004 and, the lessor of 100% of pay or $40,000 for 2003. Employee rollover contributions from other qualified retirement plans are permitted; such contributions are subject to the conditions and procedures set forth in the Plan. Participant Accounts -------------------- Each participant's account is credited with that participant's contributions and allocations of the Company's matching and discretionary contributions and Plan earnings and losses. Allocations of discretionary contributions are based on a participant's annual compensation relative to the total compensation of all other participants. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Terminating participants forfeit unvested Company contributions. Forfeitures are used to pay Plan expenses or reduce employer contributions. - 7 - INTERDIGITAL COMMUNICATIONS CORPORATION SAVINGS AND PROTECTION PLAN NOTES TO FINANCIAL STATEMENTS NOTE 1 - DESCRIPTION OF THE PLAN (Continued) Vesting ------- Participants are immediately vested in their salary deferral and rollover contributions. Vesting in Company contributions is based on length of service. Participants vest 33 1/3% on each of their first three anniversaries of employment. Participants Loans ------------------ Any participant who is an active employee may apply for a secured loan provided the request does not exceed the lesser of 50% of their vested account balance or $50,000. The minimum loan amount was $500 and $1,000 during 2004 and 2003, respectively. Only one loan per participant may be made every 365 days and all loans are subject to approval by the Plan Administrator. Loan terms are limited to five years set at the inception of each loan. During 2003, the interest rates were determined by the loan administrator in accordance with prevailing market rates on similar types of loans. Beginning in 2004, interest rates were set at an annual rate of prime + 1%. The rates of outstanding loans at December 31, 2004 and 2003 range between 4.0% and 6.0%. Interest paid by the participant is credited to the participant's account. If a participant's balance remains unpaid for more than 90 days after it is due, the loan will be in default on the outstanding loan amount and the participant's vested account will be reduced by the amount of the unpaid principal and interest. The unpaid amount is treated as a taxable withdrawal and is subject to federal income taxes. At December 31, 2004, one loan was in default in the amount of $20,193 in principal and interest. Beginning in 2004, outstanding loans become due and payable in full 60 days after the related participant ceases to be an employee and a party-in-interest, as defined under ERISA or after complete termination of the Plan. When a participant receives a distribution from the Plan, any outstanding principal plus accrued interest will be deducted from the amount of the distribution. A participant may then either default on the loan or make arrangements to continue loan repayments beyond when they become entitled to a distribution as long as their remaining interest in the Plan exceeds their outstanding loan balance. Payment of Benefits ------------------- If a participant retires, dies, becomes permanently disabled, or otherwise separates from the Company, the participant or participant's beneficiary is entitled to the vested amount of their account as valued on the applicable valuation date. In the event of a participant's death, distribution of their account will be made as soon as administratively practicable upon the receipt of appropriate documentation from their designated beneficiary. Distributions for reasons of retirement, permanent disability or termination will be made upon written request. Distributions from participant accounts are typically made, subject to certain limitations, using a single installment or deferred payment. Plan Termination ---------------- The Company may amend or suspend the Plan and may terminate the Plan at any time subject to the provisions of ERISA; although there is no present intent to do so. However, no such action may cause the Plan's assets to be used for purposes other than the exclusive benefit of the participants and their beneficiaries. If the Plan is terminated, all such participant accounts shall become fully vested and shall be distributed as soon as administratively possible. - 8 - INTERDIGITAL COMMUNICATIONS CORPORATION SAVINGS AND PROTECTION PLAN NOTES TO FINANCIAL STATEMENTS NOTE 1 - DESCRIPTION OF THE PLAN (Continued) Investment Options ------------------ All investments are participant directed except for 50% of the Company's matching contribution, which by the terms of the Plan is directed by the Company to the InterDigital Stock Fund. Participants may reallocate their holdings among available investment options at any time. However, prior to 2004, participants could not reallocate that portion of their Plan account that was attributable to the Company's matching contribution made after June 2001. During the plan years ended December 31, 2004 participants were able to allocate their contributions among the following investment options: SHORT-TERM BONDS: ---------------- Money Market Fund ----------------- This fund seeks high current income while preserving capital and providing liquidity by investing in high quality short-term cash equivalent securities, such as commercial paper, bank acceptances, and repurchase agreements.

The prior vesting policy permitted immediate vesting of 33% upon commencement of employment and vesting of 67% and 100% on the first and second anniversaries of commencement of employment, respectively. Under the current vesting policy, participants vest 33 1/3% on each of their first three anniversaries of employment. In August 2001, 400,000 shares of the Company's authorized but unissued Common Stock were reserved for issuance to the account of participants in the Plan as matching contributions. An agreement was entered into between the Company, on behalf of the Plan, and Web401(k).com and Fidelity Investments to serve as third party administrator and custodian, respectively, of the InterDigital Stock Fund. As more fully discussed in Note 3, Diversified replaced Principal, Web 401(k) and Fidelity Investments in these capacities in 2004. NOTE 2 - SUMMARY OF ACCOUNTING POLICIES The following accounting policies, which conform with accounting principles generally accepted in the United States of America, have been used consistently in the preparation of the Plan's financial statements. - 13 - INTERDIGITAL COMMUNICATIONS CORPORATION SAVINGS AND PROTECTION PLAN NOTES TO FINANCIAL STATEMENTS NOTE 2 - SUMMARY OF ACCOUNTING POLICIES (Continued) Basis of Accounting ------------------- Accounting records are maintained by the custodian on the cash basis of accounting. The financial statements of the Plan reflect all material adjustments to place the financial statements on the accrual basis of accounting. Use of Estimates ---------------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates. Investment Valuation and Income Recognition ------------------------------------------- Investments in pooled separate accounts are stated at fair value. Shares of registered investment companies are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. The InterDigital Stock Fund and The Principal Financial Group, Inc. Stock Account are valued at their year-end unit closing price (comprised of common stock market price plus uninvested cash position). Participant loans are valued at cost, which approximates fair value. Purchases and sales of investments are recorded on a trade-date basis. Interest income is accrued when earned. Dividend income is recorded on the ex-dividend date. Capital gain distributions are included in dividend income. The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the value of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits. Payment of Benefits ------------------- Benefits are recorded when paid. Forfeited Accounts ------------------ At December 31, 2004 and 2003, forfeited non-vested accounts totaled $8,000 and $7,820, respectively. These forfeited accounts were fully utilized to reduce employer matching contributions in 2004 and 2003. NOTE 3 - CUSTODIAN AND THIRD PARTY ADMINISTRATOR Effective January 1, 2004, the Plan appointed Diversified to replace Principal as the custodian and third party administrator for the majority of Plan Assets. Also effective January 1, 2004, Diversified replaced Web 401(k) and Fidelity Investments as the third party administrator and custodian, respectively, of InterDigital Common Stock held by the Plan. On December 31, 2003, Principal converted a portion of the Plan's holdings into cash in preparation for the transfer of funds to Diversified. In January 2004, Principal transferred approximately $13.9 million cash to Diversified. Diversified invested these funds into investment options offered by Diversified, in accordance with the instructions of each participant. In January 2004, Principal and Fidelity (as custodians) also transferred InterDigital Common Stock with a total fair value of approximately $1.8 million, as of December 31, 2003, to Diversified. - 14 - INTERDIGITAL COMMUNICATIONS CORPORATION SAVINGS AND PROTECTION PLAN NOTES TO FINANCIAL STATEMENTS NOTE 4 - INVESTMENT CONTRACT WITH INSURANCE COMPANIES The Guaranteed Interest Account (the "Account"), which was an investment option in 2003, provided a guaranteed interest rate for a two year and five year period. The rate credited to the Account was the rate in effect on the day each deposit was directed to the Account. To simplify reporting to Plan participants, all rates credited during 2003 were averaged into a single composite rate. The guarantees made with regard to the Account were supported by the General account of The Principal Financial Group, Inc. The General Account was invested mostly in private placement bonds, commercial mortgages and residential mortgages.
