I Item 27d - Schedule of reportable transactions for the year ended December 31, 1998......................... II All other schedules are omitted as not applicable or not required. (b) Exhibit: I - Consent of Independent Accountants SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the persons who administer the Plan have duly caused this annual report to be signed on its behalf by the undersigned, hereunto duly authorized. VIACOM INVESTMENT PLAN Date: June 28, 1999 By: /s/ Barbara Mickowski --------------------- Barbara Mickowski Member of the Retirement Committee

Report of Independent Accountants To the Participants and Administrator of the Viacom Investment Plan In our opinion, the financial statements listed in the accompanying index present fairly, in all material respects, the net assets available for benefits of the Viacom Investment Plan (the "Plan") at December 31, 1998 and 1997, and the changes in net assets available for benefits for the years then ended, in conformity with generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above. As discussed in Note 1 to the financial statements, as a result of the sale of the educational, professional and reference publishing businesses ("Non-Consumer Publishing") to Pearson plc on November 27, 1998, the Plan transferred the assets held for the participants from Non-Consumer Publishing to a qualified plan sponsored by Pearson plc. Effective January 1, 1997, the Savings and Investment Plan for Employees of PVI Transmission and Paramount Distribution Inc. merged with and into the Plan. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules as listed in the accompanying index are presented for purposes of additional analysis and are not a required part of the basic financial statements but are 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 fund information in the statements of net assets available for benefits and the statements of changes in net assets available for benefits is presented for purposes of additional analysis rather than to present the net assets available for plan benefits and changes in net assets available for benefits of each fund. The supplemental schedules and fund information are the responsibility of the Plan's management. These supplemental schedules and fund information have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

VIACOM INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS NOTE 1 - PLAN DESCRIPTION The following is a brief description of the Viacom Investment Plan (the "Plan") and is provided for general information only. Participants should refer to the Plan document for more complete information regarding the Plan. The Plan is a defined contribution plan offered on a voluntary basis to substantially all employees of Viacom International Inc. (the "Company"), a wholly-owned subsidiary of Viacom Inc. Eligible employees may become participants in the Plan following the attainment of age 21 and completion of twelve months of employment service, generally measured from date of hire. In addition, part-time employees are eligible to participate in the Plan upon completion of one thousand hours of service within a consecutive twelve-month period. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and is administered by a committee (the "Administrator") appointed by the Board of Directors of the Company. Although the Company anticipates that the Plan will continue indefinitely, it reserves the right by action of its Board of Directors to amend or terminate the Plan provided that such action does not retroactively reduce earned participant benefits. On October 26, 1998 and November 27, 1998, the Company completed the sale of its music retail stores ("Music") to Wherehouse Entertainment, Inc. and its educational, professional and reference publishing businesses ("Non-Consumer Publishing") to Pearson plc, respectively. As a result, the Plan was amended such that the plan participants employed in these businesses were deemed to be fully vested in the value of their accrued benefits as of the respective dates of disposition. Subsequent to the Music sale, the Plan participants from the Music business were entitled to the normal payment options offered to terminated employees. On December 31, 1998, all of the assets held for the Plan participants from the Non-Consumer Publishing business, except for the assets held in the Certus Interest Income Fund, were transferred to a qualified plan sponsored by Pearson plc; the assets held in the Certus Interest Income Fund were transferred on January 27, 1999. Effective January 1, 1997 the Savings and Investment Plan for Employees of PVI Transmission and Paramount Distribution Inc. merged with and into the Plan. Effective January 1, 1997, Plan participant accounts in the Putnam Voyager Fund, Putnam Fund for Growth and Income, George Putnam Fund of Boston, Putnam Investors Fund and the Putnam Income Fund were converted to a class of shares that are subject to a lower annual fund expense. Investment and participant accounts Putnam Fiduciary Trust Company (the "Trustee") is the trustee and custodian of Plan assets. 10

VIACOM INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS Plan participants have the option of investing their contributions or existing account balances among the following funds: Growth Putnam S&P 500 Index Fund (effective July 1, 1997) This fund invests primarily in publicly traded common stocks either directly or through collective investment trusts having a similar investment objective. The fund is designed to achieve a return, before the assessment of any fees, that closely approximates the return of the Standard & Poor's 500 Composite Stock Price Index. Putnam Investors Fund This fund seeks long-term growth of capital and any increased income that results from this growth. The fund is designed for investors seeking long-term growth of capital from a portfolio primarily consisting of quality common stocks. Putnam Voyager Fund This fund seeks capital appreciation by investing in a combination of stocks of smaller companies expected to grow over time as well as stocks of larger, more established corporations. The fund is designed for investors seeking a diversified portfolio offering the opportunity for capital growth while also providing current income. Europacific Growth Fund This fund, a registered investment company, is managed by the Capital Research and Management Company and invests in stocks of companies outside of the United States. Its performance will fluctuate with the value of the foreign exchange markets and the underlying stocks. Viacom Inc. Common Stock Fund This fund invests in shares of Viacom Inc. Class B Common Stock. Growth and Income George Putnam Fund of Boston This fund seeks to provide a balanced investment composed of a well-diversified portfolio of stocks and bonds that will produce both capital growth and current income. Putnam Fund for Growth and Income This fund seeks capital growth and current income. The fund is designed for investors seeking long-term growth of capital from a portfolio primarily consisting of attractively priced stocks, offering the opportunity for capital growth while also providing current income. Income Putnam Income Fund This fund seeks high current income consistent with what the Trustee believes to be prudent risk. This fund invests in a variety of bonds, including corporate bonds from creditworthy companies. 11

VIACOM INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS Capital Preservation Certus Interest Income Fund This fund is managed by Certus Financial Corporation and seeks to preserve principal and minimize market volatility while offering a competitive and predictable rate of return. This fund invests in guaranteed investment contracts and synthetic investment contracts. Synthetic investment contracts consist of benefit responsive wrapper contracts backed by investments which are held in the trust and owned by the Plan. Each of the funds, except for the Certus Interest Income Fund, the Europacific Growth Fund and the Viacom Inc. Common Stock Fund are registered investment companies managed by Putnam Management Company, Inc. and, therefore, are identified as parties-in-interest. The Viacom Inc. Common Stock Fund is also identified as a party-in-interest as it invests in shares of Viacom Inc. Class B Common Stock. Investment elections are required to be in multiples of 5% of the amount contributed and can be changed at any time. The Plan is intended to meet the requirements of ERISA Section 404(c). Thus, to the extent participants exercise control over the investment of contributions, neither the Plan nor any other Plan fiduciary will be responsible for any losses which may occur. Effective January 1, 1994, the Company and certain affiliated companies entered into a master trust agreement (the "Master Trust") with the Trustee to combine certain investments of the Plan, affiliated companies' plans, and, effective October 1, 1995, a separate Collective Bargaining Plan (the "CBP"). The Master Trust currently holds assets for the Plan and the CBP Plan. The Master Trust assets are managed by Certus. However, the Trustee records the activity of each plan separately in order to distinguish the specific assets available to each plan. Net investment assets and net investment earnings on the investments of the Master Trust are allocated daily to the plans participating in the Master Trust. Such allocation is based on the ratio of net investment assets of each of the participating plans to total net investment at the time the Master Trust was formed, adjusted for any contributions or disbursements attributable to specific participating plans. Note 8 sets forth the Plan's proportionate interest in the Master Trust, and certain financial information of the Master Trust. Employer matching contributions are currently invested entirely in Viacom Inc. Class B Common Stock. Loans to Participants The Loan Fund is a separate fund established solely for the purpose of administering loans to participants. Participants are eligible to receive loans based on their account balances. The maximum loan available to a participant is the lesser of 50% of the participant's vested account balance or $50,000, reduced by the highest outstanding balance of any Plan loan made to the participant during the twelve month period ending on the day before the loan is made. The minimum loan available to a participant is $500. The interest rate on participant loans is established on the first day of the calendar quarter at a rate of 1% above the prime commercial rate. Effective January 1, 1996, only one loan may be outstanding at one time. Participants may elect repayment periods from twelve to sixty months through payroll deductions commencing as soon as administratively possible following the distribution 12

VIACOM INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS of the loan. The Plan allows participants to elect a repayment term of up to 300 months for loans used for the acquisition of a principle residence. Transfers of participant balances for loan disbursements and repayments of loan principal and interest to the Loan Fund are specifically identified in the respective participants' accounts within each fund. Contributions The Plan permits participants to contribute up to 15% of annual compensation on a before-tax, after-tax or combination basis, subject to the Internal Revenue Code ("IRC") limitations set forth below. The employer's matching contribution is equal to (i) 50% of the first 6% of annual compensation that is contributed on a before-tax basis if base pay is $65,000 or less at a specified date or (ii) 50% of the first 5% of annual compensation contributed on a before tax basis if base pay is greater than $65,000. A new Plan participant is permitted to rollover into the Plan part or all of distributions from an individual retirement account, individual retirement annuity or another qualified plan. The IRC limits the amount of annual participant contributions that can be made on a before-tax basis; the limit was $10,000 and $9,500 for 1998 and 1997, respectively. Total compensation considered under the plan, based on IRC limits, may not exceed $160,000 for 1998 and 1997. The IRC also contains an annual limit on aggregate participant and employer contributions to defined contribution plans equal to the lesser of $30,000 or 25% of compensation. All contributions made to the Plan on an annual basis may be further limited due to certain non-discrimination tests prescribed by the IRC. Vesting Participants in the Plan are immediately vested in their own contributions and earnings thereon. After January 1, 1996, the employer's matching contribution will vest at 20% per year of service, becoming fully vested after five years of service. Employees who on December 31, 1995 were participants in the Plan, or other defined contribution plans which were merged with and into the Plan effective January 1, 1996, will be covered by the vesting schedules in effect at that time if they are more favorable. If participants terminate employment prior to being vested in their employer matching contributions and receive a distribution of the vested portion of their account, the non-vested portion of their account is forfeited and used to pay administrative expenses and to fund future employer matching contributions. Employer matching contributions of $1,138,762 and $785,420 during the years ended December 31, 1998 and December 31, 1997, respectively, were forfeited by terminating employees before those amounts became vested. 13

VIACOM INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS Distributions and Withdrawals Earnings on both employee and employer contributions are not subject to income tax until they are distributed or withdrawn from the Plan. Participants in the Plan, or their beneficiaries, may receive their account balances, in a lump sum or in installments over a period of up to 20 years, in the event of retirement, termination of employment, disability or death. Participants must receive a required minimum distribution upon attainment of age 70 1/2 even if they are still employed. Participants who have been in the Plan or affiliated plans at least five years may elect to withdraw up to 100% of their employer matching contribution account and earnings thereon, while those who have participated less than five years are limited to withdrawing vested employer matching contributions made at least two years prior to the withdrawal including earnings thereon. In addition, participants in the Plan may receive part or all of their after-tax and rollover contributions. Upon attainment of age 59 1/2, participants may withdraw all or part of their before-tax contributions and earnings thereon. All of the above withdrawal elections are subject to a provision that a participant can make only one such request during each calendar year. A participant may obtain a hardship withdrawal of vested portion of employer matching contributions and before-tax contributions (including the pre-1989 earnings thereon) provided that the requirements for hardship are met. There is no restriction on the number of hardship withdrawals permitted. Plan Expenses The Company pays for expenses incurred in connection with the administration of the Plan and the investment of Plan assets, to the extent not covered by forfeitures. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Accounting Method The accrual method of accounting is used for financial statement presentation. Investment Valuation and Income Recognition Short-term money market obligations are carried at cost which approximates fair value due to the short-term maturity of these investments. Viacom Inc. Class A Common Stock and Class B Common Stock are reported at fair value based on the quoted market price of the stock on the American Stock Exchange, Inc. Investments with registered investment companies are reported at fair value based upon the market value of the underlying securities as priced by national security exchanges. Guaranteed investment income contracts and synthetic investment contracts held by the Master Trust are reported at contract value. Participant loans consist of the outstanding principal of loans to Plan participants at December 31, 1998 and 1997. The loans outstanding as of December 31, 1998 and 1997 carry interest rates ranging from 6.5% to 12.5%. Cash and cash equivalents are valued at cost plus accrued interest, which approximate market value. Interest income is accrued as earned and divided income is recorded on the ex-dividend date. 14

VIACOM INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS Security Transactions Purchases and sales of securities are recorded on the trade date. The historical average cost basis is used to determine gains or losses on security dispositions. The Plan presents in the statement of changes in net assets available for benefits the net appreciation (depreciation) in the fair value of its investments which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Payment of Benefits Benefits are recorded when paid. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires the Plan to make estimates and assumptions, such as those regarding fair value, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of changes in net assets available for benefits during the reporting period. Actual results could differ from those estimates. NOTE 3 - SUBSEQUENT EVENTS Effective May 1, 1999, the Plan participants from Blockbuster Inc. ("Blockbuster Participants"), a subsidiary of the Company, became covered by the Blockbuster Investment Plan, a defined contribution 401(k) plan sponsored by Blockbuster Inc. On April 30, 1999, the Plan's account balances of all Blockbuster Participants were transferred to the Blockbuster Investment Plan. Generally, the terms of the Blockbuster Plan are similar to those of the Plan. On April 8, 1999, Viacom Inc. moved the listing of its stock to the New York Stock Exchange from the American Stock Exchange, Inc. On February 25, 1999, the Board of Directors of Viacom Inc. declared a 2-for-1 common stock split, effected in the form of a dividend. The additional shares were issued on March 31, 1999 to shareholders of record on March 15, 1999. All common share and per share amounts have been adjusted to reflect the stock split for all periods presented. 15

NOTE 6 - INCOME TAX STATUS The Plan, as amended through January 1, 1998, received a favorable determination letter from the Internal Revenue Service, dated January 22, 1998, with respect to the qualified status of the Plan under Section 401(a) of the IRC and is, therefore, exempt from federal income taxes under the provisions of Section 501(a) of the IRC. The Plan has been amended since receipt of the determination letter. However the Company and the Company's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. NOTE 7 - TERMINATION PRIORITIES In the event that the Plan is terminated, subject to conditions set forth in ERISA, the Plan provides that the net assets of the Plan be distributed to participants in proportion to their respective vested interests in such net assets at that date. 18

VIACOM INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS NOTE 8 - INVESTMENT IN MASTER TRUST The value of the Plan's interest in the total investments of the Master Trust was 99.4% at December 31, 1998 and 1997, and the allocated share of investment income was 99.4% and 99.1% for the respective years then ended. The following table presents the fair value of investments of the Master Trust: December 31, ------------ 1998 1997 ---- ---- Guaranteed investment contracts ........... $ 54,001,585 $ 41,304,438 Synthetic investment contracts ............ 22,521,317 41,580,832 Putnam short-term investment fund ......... 16,355,305 6,049,215 Payable to other plan .....................

(89,454) (97,518) ------------ ------------ Net Investment Income ........... $ 5,493,966 $ 5,642,173 ============ ============ The guaranteed investment contracts and synthetic investment contracts are fully benefit-responsive and are therefore presented in the financial statements at contract value. The Company does not expect any employer initiated events that may cause premature liquidation of a contract at market value. At December 31, 1998 and 1997, the fair value of such assets in the aggregate was $94,226,538 and $90,618,702 respectively, with an average yield of 6.31% and 6.42%, respectively. The return on assets for the year ended December 31, 1998 and 1997 was 6.46% and 6.61%, respectively.
