INDEPENDENT AUDITORS' REPORT To the Plan Administrator of the CBS Employee Investment Fund We have audited the accompanying statements of net assets available for benefits of the CBS Employee Investment Fund ("the Plan") as of September 1, 2001 and December 31, 2000, and the related statement of changes in net assets available for benefits for the period January 1, 2001 through September 1, 2001. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above, present fairly, in all material respects, the net assets available for benefits of the Plan as of September 1, 2001 and December 31, 2000, and the changes in net assets available for benefits for the period January 1, 2001 through September 1, 2001 in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The supplemental schedule of reportable transactions is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements for the period January 1, 2001 through September 1, 2001 and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

CBS EMPLOYEE INVESTMENT FUND Notes to Financial Statements - -------------------------------------------------------------------------------- 1. DESCRIPTION OF THE PLAN The CBS Employee Investment Fund ("the Plan") was established by CBS Broadcasting Inc. (the "Company") (formerly CBS Inc.) a wholly owned subsidiary of CBS Corporation (the "Corporation" or "CBS") (formerly conducted business as Westinghouse Electric Corporation). On May 4, 2000, CBS was merged with and into Viacom Inc. ("Viacom"). Viacom became the sponsor of the Plan effective with the merger. The Viacom Retirement Committee serves as the plan administrator. The Plan was established to provide a convenient way for employees of the Company to save and invest for retirement. The Plan is considered a defined contribution type of profit sharing plan and, is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Plan Mergers and Amendments --------------------------- Viacom 401(k) Plan Merger Effective after the close of business on August 31, 2001, the assets and liabilities of the Plan merged into the Viacom 401(k) Plan, and the Plan ceased to exist as a stand-alone plan. Certain provisions of the Viacom 40l (k) Plan differ from those provisions of the Plan that were effective prior to the merger. Participants should refer to the Viacom 401 (k) Plan document, as amended effective September 1, 2001, for provisions applicable to Plan participants. Other Effective January 1, 2000, the Plan was amended to allow all active employees of the Westinghouse Savings Program, another qualified plan sponsored by the Company, to become participants of the Plan. Effective January 1, 2000, the Plan was amended to provide for certain participants of the Plan to be transferred to the Infinity Broadcasting Corporation Employees' 401(k) Plan, another qualified plan sponsored by a Viacom subsidiary. Effective January 1, 2001, the Plan was amended to merge the King World Productions, Inc. Retirement Savings Plan (King World) into the Plan. On January 2, 2001, assets for 155 King World participants were transferred to the Plan. Plan Provisions --------------- The following is a brief description of certain provisions of the Plan, effective prior to the merger with the Viacom 401(k) Plan. Participants should refer to the Plan document for the complete Plan provisions. 4

CBS EMPLOYEE INVESTMENT FUND Notes to Financial Statements - -------------------------------------------------------------------------------- 1. DESCRIPTION OF THE PLAN (continued) Eligibility All employees of the Company and certain of its subsidiaries in the United States, as well as U.S. citizens abroad, who are employed on a full-time basis in executive, non-union office and hourly positions, are eligible to participate in the Plan immediately. Employees working on a part-time basis are eligible to participate in the Plan upon the completion of one year of employment, if the employee worked at least 1,000 hours in that year. Other groups designated by the Company or by the terms of a collective bargaining agreement are also eligible to participate in the Plan. Investment Options Pursuant to the May 4, 2000 merger between CBS and Viacom, each share of CBS common stock held by the Plan was converted into 1.085 shares of Viacom Class B Common Stock. On February 14, 2001, Infinity Broadcasting Corporation merged into Viacom. Pursuant to the merger, each share of Infinity stock held in the Infinity Stock Fund was converted into 0.592 of shares of Viacom Class B Common Stock. The Plan had eleven investment options, which were: Stable Value Fund, Short Term Life Cycle Fund, Medium Term Life Cycle Fund, Long Term Life Cycle Fund, S&P Index Fund, Active U.S. Equity Fund, Small Cap U.S. Equity Fund, International Equity Fund, Company Stock Fund, Infinity Stock Fund and the Self-Directed Account. As a result of the merger of the Plan with the Viacom 401(k) Plan, any amounts previously designated for investment in the Active U.S. Equity and the International Equity Funds were transitioned into the Barclays Global Investors S&P 500 Index and Capital Guardian International Equity Funds, respectively. Employees are allowed to transfer balances among any of the fund options in increments of 1%. The Self-Directed Account allows Plan participants to establish an investment account with the trustee and gain access to an expanded number of investment options. A Self-Directed Account can be established if the participant has a Plan balance of at least $5,000; the minimum initial investment option is $2,500. Additional transfers into the Self-Directed Account must be in $1,000 increments. Fees are charged on transactions in the Self-Directed Account and are charged directly against the participant's Self-Directed Account balance. 5

CBS EMPLOYEE INVESTMENT FUND Notes to Financial Statements - -------------------------------------------------------------------------------- 1. DESCRIPTION OF THE PLAN (continued) Participant Loans Additionally, the Plan maintains a Loan Provision Fund for outstanding participant loans as discussed below. The Plan allows employees to request loans from their account without incurring a taxable event. Participants may request loans for a minimum of $1,000, but not to exceed the lesser of $50,000 (reduced by the highest outstanding balance of any loan from the Plan during the prior twelve months) or one half of the market value of the vested portions of all the participant's separate accounts on the date of the loan. No more than one loan may be made per year, and not more than two loans may be outstanding. When a participant has two loans, one of the outstanding loans must be for the purpose of purchasing a primary residence. Interest on participants' loans are based on the latest blended rate for the Stable Value Fund, rounded to the nearest quarter percentage point, as of the valuation date of the calendar quarter preceding the loan's effective date. The loans must be repaid within five years, with the exception of a loan used to acquire a primary residence, for which repayment is not to exceed fifteen years. In the event of default on a loan payment, all remaining payments are considered immediately due and payable. The defaulted portion of any outstanding loan including accrued interest is offset against the remaining balance in the participant's account. Contributions Employee participation in the Plan is voluntary. Employee contributions can be between 1% and 15% of base annual salary on a before or after-tax basis. Employees may contribute, on a before-tax basis, up to a maximum of $10,500. Participants may also make additional voluntary lump sum contributions on an after-tax basis. Employee contributions are directed by participants to any combination of funds, as designated by the employee. Allocations to the funds may be made in 1 percentage point increments. The Company may make performance based discretionary contributions to the Plan. Company matching contributions are based on employees' before-tax contributions (up to a maximum of 5% of eligible pay). In 2001 and 2000, the Company match equaled 50% of each $1.00 contributed on a before-tax basis up to 5% of eligible pay. Employer contributions are initially directed to the Company Stock Fund. Employees can subsequently transfer the employer contribution, in increments of 1% to any of the fund options. 6

CBS EMPLOYEE INVESTMENT FUND Notes to Financial Statements - -------------------------------------------------------------------------------- 1. DESCRIPTION OF THE PLAN (continued) Contributions (continued) Company contributions become vested at the rate of 33-1/3% per annum until fully vested after three years of employment. The overall maximum annual contribution to the Plan for a participant, including before-tax, after-tax and Company matching contributions is $30,000 or 25% of an employee's base pay. All employer and employee contributions are subject to specified limitations as described in ERISA and other applicable federal and state laws. Distributions Upon termination, most participants have the option of receiving the balance in their accounts in cash, monthly or annual payments over a period of time not to exceed 240 months. For terminated participants, who have an account balance in excess of $5,000, an option is available to leave their account balance in the Plan and have it distributed at any valuation date provided however, that payments commence no later than April 1, of the year following the year in which they reach age 70 1/2. Terminated participants with account balances of less than $5,000 receive a mandatory lump sum payment. Non-vested employer contributions are forfeited upon termination and are used to reduce future employer contributions and for plan expenses. At September 1, 2001 and December 31, 2000, forfeited non-vested amounts were $181,758 and $180,406, respectively. Withdrawals of a participant's after tax contributions account are permitted at any time, but are limited to two withdrawals per calendar year. Withdrawals of a participant's tax-deferred contributions are permitted after the participant has reached age 59-1/2, or before reaching such age in the event of hardship, but are limited to two withdrawals per calendar year. The Tax Reform Act of 1986 imposed a 10% penalty on certain withdrawals and distributions made before the participant reaches age 59-1/2. 2. SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation --------------------- The financial statements of the Plan have been prepared under the accrual method of accounting. 7

CBS EMPLOYEE INVESTMENT FUND Notes to Financial Statements - -------------------------------------------------------------------------------- 2. SIGNIFICANT ACCOUNTING POLICIES (continued) Basis of Presentation (continued) --------------------- As a result of the merger of the Plan with the Viacom 401 (k) Plan, the financial statements presented are as of September 1, 2001 and for the period January 1, 2001 through September 1, 2001. Investment Valuation -------------------- An individual participant's interest in the funds of the Plan is represented by the dollar value of the participant's individual account. Investments, except for certain guaranteed annuity and investment contracts, are stated at fair value. Investments in securities traded on a national securities exchange are valued at the closing sales price on the last business day of the year; securities traded in the over-the-counter market and listed securities for which no sale was reported on that date are valued at the last reported bid price; participations in pooled trust funds are stated at the Trust's beneficial interest in the aggregate fair value of assets held by the particular fund as reported by the Plan's fund manager. The carrying value of the Plan's investment in the guaranteed annuity contracts and guaranteed investment contracts is cost plus accrued interest. Investment Transactions and Investment Income --------------------------------------------- Purchases and sales of securities are reflected on a trade-date basis. Gain or loss on sales of securities is based on average cost. Dividend income is recorded on the ex-dividend date. Income from other investments is recorded as earned on an accrual basis. The net appreciation (depreciation) of investments, consists of the realized gains and losses and the unrealized appreciation (depreciation) on those investments, as reflected in the Statement of Changes in Net Assets Available for Benefits. Payment of Benefits ------------------- Benefits are recorded when paid. Use of Estimates ---------------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Plan Administrator to make estimates and assumptions that affect the reported amounts and disclosures. Accordingly, actual results could differ from those estimates. 8
