Report of Independent Accountants

To the Participants and
Administrator of the
Viacom Investment Plan

In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Viacom Investment Plan (the "Plan") at December 31, 2000 and 1999, and
the changes in net assets available for benefits for the year ended December 31,
2000, in conformity with accounting principles generally accepted in the United
States of America. 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 auditing standards generally accepted in the
United States of America, which require that we plan and perform the audits 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 our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule listed in the
accompanying index 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 is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

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. Effective January 1, 2001, the service requirement
for full time employees was eliminated. 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 appointed by the board of
directors of Viacom Inc.

Effective April 1, 2000, the net investments of participants who were employees
of the MTVi Group, L.P. ("MTVi"), a limited partnership in which the Company
owns a majority interest, were transferred to the MTVi Investment Plan, a
defined contribution 401(k) plan sponsored by MTVi.

Investment and participant accounts
-----------------------------------

Putnam Fiduciary Trust Company (the "Trustee") is the trustee and custodian of
Plan assets. Certain Plan investments are shares of funds managed by the Trustee
and therefore qualify as party-in-interest transactions. Current employer
matching contributions are invested entirely in Viacom Inc. Class B Common
Stock.

Plan participants have the option of investing their contributions or existing
account balances among the following funds:

  Certus Interest Income Fund

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, affiliated companies' plans and the
CBP. 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 7 sets forth
the Plan's proportionate interest in the Master Trust and certain financial
information of the Master Trust.

                          NOTES TO FINANCIAL STATEMENTS



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 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 employee 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 $10,500 and $10,000 for 2000 and 1999,
respectively. Total compensation considered under the Plan, based on IRC limits,
may not exceed $170,000 and $160,000 for 2000 and 1999, respectively. 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. Employer matching contributions will vest at 20% per year of
service, becoming fully vested after five years of service. 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.
During the year ended December 31, 2000, employer matching contributions of
$593,431 were forfeited by terminating employees and were used as noted above.

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 annual prime commercial rate and 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 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 principal 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 and allocated in accordance
with their current investment elections.

                          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 vested
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 unless 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 the vested portion of employer
matching contributions and before-tax contributions provided that the
requirements for hardship are met. There is no restriction on the number of
hardship withdrawals permitted.

Termination Priorities
----------------------

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.

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.

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

Basis of Accounting
-------------------

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 New York Stock
Exchange. 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, which represents the aggregate amount of deposits thereto, plus interest
at the contract rate, less withdrawals. Participant loans consist of the
outstanding principal of loans to Plan participants at December 31, 2000 and
1999. The loans outstanding as of December 31, 2000 and 1999 carry interest
rates ranging from 7.0% to 12.5%. Cash and cash equivalents are valued at cost
plus accrued interest, which approximates market value. Interest income is
accrued as earned and dividend income is recorded on the ex-dividend date.

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.

                          NOTES TO FINANCIAL STATEMENTS

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.

Risks and Uncertainties
-----------------------

The Plan provides for various investment options. Investment securities are
exposed to various risks such as interest rate, market and credit. Due to the
level of risk associated with certain investment securities and the level of
uncertainty related to changes in the value of such securities, it is at least
reasonably possible that changes in risks in the near term could materially
affect participants' account balances and the amounts reported in the statements
of net assets available for benefits and the related statement of changes in net
assets available for benefits.

NOTE 3 - INVESTMENTS

Individual investments that represent greater than 5% of net assets available
for benefits are identified below:

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.

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,
2000 and 1999, the fair value of the investments in the Master Trust in the
aggregate was $55,572,187 and $53,172,193 respectively, with an average yield of
6.61% and 6.31% for the respective years then ended. The return on assets for
the year ended December 31, 2000 and 1999 was 6.50% and 6.35%, respectively. The
synthetic investment contract interest rates are evaluated on a quarterly basis
and may be reset when the expected cash flow characteristics of an underlying
security change.
