PART I

ITEM 1.  BUSINESS.

GENERAL

CBS Corporation is one of the largest radio and television broadcasters in the
United States and operates the largest outdoor advertising business in North
America. We operate our businesses primarily in the United States through our
Infinity, Television, Cable and Internet Group business segments. The Infinity
segment consists of radio stations and outdoor advertising businesses. The
Television segment consists of 16 owned and operated television stations which
are integrated with our television network and television syndication
operations. Our television and radio stations are operated under licenses from
the Federal Communications Commission (FCC). The Cable segment consists of cable
networks, including The Nashville Network (TNN), Country Music Television (CMT)
and two regional sports networks. The Internet Group segment, formerly referred
to as the New Media segment, consists of our interests in Internet based
companies, certain of which are consolidated and others accounted for under the
cost or equity method of accounting.

On September 6, 1999, we entered into an agreement and plan of merger, as
amended, with Viacom Inc. (Viacom). Viacom is a diversified entertainment
company with operations in six segments: Networks, Entertainment, Video, Parks,
Publishing and Online. See note 2 to the financial statements.

We have dramatically redefined our business portfolio and strategic direction in
recent years. Through acquisitions and divestitures we have essentially
transformed ourselves from an industrial company to a media company. A number of
significant acquisitions in 1999 and in recent years contributed to the
successful execution of our strategy. We acquired CBS Inc. in November 1995; the
radio and outdoor advertising business of Infinity Media Corporation in December
1996; Gaylord Entertainment Company's two major cable networks, TNN and CMT, in
September 1997; the radio broadcasting operations of American Radio Systems
Corporation (American Radio) in June 1998; the television syndication operations
of King World Productions, Inc. (King World) in November 1999; and, through our
majority owned subsidiary, Infinity Broadcasting Corporation (Infinity
Broadcasting), acquired Outdoor Systems, Inc. (Outdoor Systems), an outdoor
advertising business, now known as Infinity Outdoor, Inc. (Infinity Outdoor), in
December 1999. For information about significant mergers and acquisitions, see
note 2 to the financial statements.

We have also adopted various disposal plans that, in the aggregate, provide for
the disposal or liquidation of all of our industrial and financial services
businesses. The assets and liabilities and the results of operations for these
businesses are classified as Discontinued Operations for all periods presented
in our financial statements. At December 31, 1999, essentially all of the
industrial businesses were divested, all in accordance with the terms of their
respective agreements. See notes 12 and 19 to the financial statements.

In August 1998, we formed a new company named Infinity Broadcasting comprising
our radio and outdoor advertising businesses. In December 1998, Infinity
Broadcasting issued approximately 18% of its common stock in an initial public
offering (IPO). After giving effect to the offering, we beneficially owned
approximately 82% of Infinity Broadcasting's equity, which represented 96% of
its combined voting power. On December 7, 1999, Infinity Broadcasting exchanged
1.25 of its shares of Class A common stock for each outstanding common share of
Outdoor Systems. The closing of this transaction caused a reduction in our
ownership and voting interests in Infinity Broadcasting to approximately 65% and
90%, respectively, excluding the dilutive effect of stock options, at December
31, 1999.

We were founded in 1886 and operate under a corporate charter granted by the
Commonwealth of Pennsylvania in 1872.

BUSINESS SEGMENTS

Financial and other information by segment is included in note 18 to the
financial statements.

Infinity

The Infinity segment is comprised of the radio and outdoor advertising
businesses of Infinity Broadcasting. The Infinity segment is characterized as
out-of-home media because the majority of radio listening and virtually all
viewing of outdoor advertising takes place in automobiles, transit systems, on
the street and other locations outside the consumer's home, including listening
to radio at work. Infinity Broadcasting acquired American Radio in June 1998 as
part of its continued strategy of pursuing acquisitions in the top 50 markets.
In December 1999, Infinity Broadcasting acquired Outdoor Systems.

On March 3, 2000, Infinity Broadcasting entered into an asset purchase agreement
to acquire 18 radio stations, located in the top 50 markets, from Clear Channel
Communications, Inc. (Clear Channel Communications) for approximately $1.4
billion. This transaction is expected to close by year-end 2000 and is subject
to regulatory reviews and approvals. In addition, on March 21, 2000, Infinity
Broadcasting announced that it had entered into an agreement to purchase
Giraudy, one of France's largest outdoor advertising companies, for
approximately $425 million. This transaction is expected to close mid-year 2000.

Infinity Broadcasting owns and operates 162 radio stations located in 34
markets. Sixty-two of these radio stations are in the nation's ten largest radio
markets. We believe that the presence of Infinity's radio stations in large
markets makes it attractive to advertisers and that the overall diversity of its
stations reduces its dependence on any single station, local economy, or
advertiser. These stations serve diverse target demographics through a broad
range of programming formats, such as rock, oldies, news/talk, adult
contemporary, sports/talk, and country, and include leading franchises in news,
sports, and personality programming. Infinity Broadcasting also has a minority
equity investment in Westwood One, Inc. (Westwood One), which it manages.
Westwood One produces and distributes syndicated and network radio programming
and also manages the CBS Radio Network. In order to take advantage of the
growing opportunity in the internet market, the vast majority of the radio
stations operate web sites. These web sites focus on the local markets,
promoting the stations' talent and programming, and providing news, information
and entertainment, as well as other services to the stations' listeners.

Infinity Broadcasting operates the largest outdoor advertising business in North
America through its wholly owned subsidiaries. Our outdoor advertising business
sells advertising space throughout the United States, United Kingdom, Republic
of Ireland, Canada, Mexico and the Netherlands on various media, including
buses, trains, malls, train platforms and terminals throughout commuter rail
systems, and on painted billboards, eight and thirty-sheet posters and phone
kiosks.

Television

The Television segment consists of three integrated operations: the CBS
television network; our owned and operated television stations; and our
television syndication operations. In November 1999, we acquired King World, a
leading syndicator of television programming.

The CBS television network produces or acquires, and distributes a comprehensive
schedule of news, public affairs, entertainment and sports programming, to our
owned and operated television stations and more than 200 affiliates. Our owned
and operated television stations and domestic affiliates serve, in the
aggregate, all 50 states and the District of Columbia. The television network is
responsible for sales of advertising time for the television network broadcasts
of news, public affairs, sports and entertainment programming.

We own and operate 16 television stations located in eight of the nation's ten
largest markets and 12 of the nation's top 20 markets reaching approximately 34%
of all U.S. television households. The CBS owned stations are: WCBS-TV New York,
KCBS-TV Los Angeles, WBBM-TV Chicago, KYW-TV Philadelphia, KPIX-TV San
Francisco, WBZ-TV Boston, KTVT-TV Dallas-Fort Worth, WWJ-TV Detroit, WCCO-TV
Minneapolis, WFOR-TV Miami, KCNC-TV Denver, KDKA-TV Pittsburgh, WJZ-TV
Baltimore, KUTV-TV Salt Lake City, KEYE-TV Austin and WFRV-TV Green Bay. The
stations produce news and broadcast public affairs and other programming to
serve their local markets and offer the CBS television network and syndicated
programming. Many

                                                       CBS CORPORATION         3
<PAGE>   4

of our television stations currently operate web sites which promote the
stations' talent and programming, and provide news, information and
entertainment, as well as other services to the stations' viewers.

Our programming also involves the production, distribution and marketing of
first-run and off-network syndicated programming to television stations, cable,
home video, in-flight and emerging media worldwide. Subsequent to year-end 1999,
we approved a proposed plan to integrate the newly acquired operations of King
World with the existing CBS syndication business to achieve synergies and
eliminate redundant functions. See notes 2 and 13 to the financial statements.

The success of our television segment is driven primarily by programming. Our
network depends on our owned and operated television stations, our television
syndication operations and the affiliates for distribution of the programming.
In addition, the network provides the majority of programming aired at our owned
and operated television stations.

Cable

The Cable segment primarily consists of our cable networks, including TNN, CMT
and two regional sports networks. These networks are distributed by cable
television and other multi-channel technologies.

TNN is an advertiser-supported cable network featuring country lifestyle and
entertainment programming. This network serves approximately 76 million U.S.
homes. TNN offers a broad array of programming from original series to movies to
country music concerts as well as motorsports, including the NASCAR Winston Cup
Races, outdoor sports such as hunting and fishing, professional bull riding and
sports entertainment such as wrestling. In April 2000, TNN is expected to be the
primary network for the Arena Football League. Our rights to broadcast the
NASCAR Winston Cup races were not renewed and expire during the year 2000.

CMT is an advertiser-supported, 24-hour cable network with a country music video
format. It reaches approximately 39 million U.S. homes.

In addition, we own and operate the Midwest Sports Channel, a regional sports
network in Minneapolis, and we are a majority owner of Home Team Sports, a
regional sports network serving the mid-Atlantic states.

Also part of the cable operations, Group W Network Services (GWNS) is a global
provider of satellite services to broadcast, cable and corporate networks. Based
in Stamford, Connecticut, GWNS provides transmission and other technical
services to U.S. broadcast networks and to many major cable networks.

Internet Group

The Internet Group segment consists of our consolidated and nonconsolidated
Internet businesses including CBS.com, Inc. the operator of two Internet
sites--CBS.com and CBSNews.com. CBS.com, which launched in February 1998, offers
a broad range of informational, entertainment, news and promotional content. In
January 2000, CBS.com, Inc. launched CBSNews.com, a news and news related
information web site. A majority of the television network affiliates currently
participate in these web sites. In addition, during the second half of 1999, we
closed on a number of strategic investments focused on growing our Internet
based operations. We received an equity interest in these Internet companies,
primarily in exchange for future advertising and promotion time on our
television, radio, outdoor and cable media properties. In exchange for providing
advertising and promotion time on its media properties, Infinity Broadcasting
will be provided an economic interest in certain of these Internet investments.

COMPETITION

The broadcast environment and the outdoor advertising industry are highly
competitive. The Telecommunications Act of 1996 (the Act) has provided both new
opportunities and potential new competition for us. By deregulating station
ownership limits, the Act has allowed us to pursue strategic growth in our
businesses.

                                                       CBS CORPORATION         5
<PAGE>   6

Our out-of-home media business competes for audiences and advertising revenues
directly with other radio stations and outdoor advertising companies, as well as
with other media, such as broadcast television, newspapers, magazines, cable
television, the Internet and direct mail, within their respective markets.

The radio and outdoor advertising industry is also subject to competition from
new media technologies that are being developed or introduced, such as the
delivery of audio programming by cable television systems, by satellite and by
terrestrial delivery of digital audio broadcasting. The FCC has recently
authorized spectrum for the use of a new technology, satellite digital audio
radio services, to deliver audio programming. The FCC has adopted licensing and
operating rules for this service and awarded two licenses. Satellite digital
audio radio service may provide a medium for the delivery by satellite of
multiple new audio programming formats to local and national audiences. Digital
technology also may be used in the future by existing radio broadcast stations
either on existing (a so-called "in-band on-channel" approach) or alternate
broadcasting frequencies. The FCC has begun a proceeding to explore the
authorization of a digital radio service. The FCC also recently issued a Report
and Order creating a new "low power" FM radio service which could open up
opportunities for low cost "neighborhood" service. The radio industry is
challenging this FCC ruling through legal and legislative action.

For the sale of advertising time, the CBS television network, television
stations and the cable operations compete for audiences with other television
networks, television stations and cable networks, as well as with other media,
including satellite television services, videocassettes and the Internet. The
CBS television network, television stations and the cable operations also
compete with other video media for distribution rights to television programming
leading to escalating costs for the program rights to broadcast marquee events.
In addition, the CBS television network competes with other television networks
to secure affiliations with independently owned television stations in markets
across the country, which are necessary to ensure the effective distribution of
network programming to a nationwide audience. Broadcast television, including
CBS, has experienced a decline in total audience viewership in recent years.
And, among the major networks, CBS delivers an audience that has an older
demographic. An older demographic may result in lower revenue for an advertising
spot.

An extended conversion to digital television broadcasting has begun. Current and
future technological developments may affect competition within the television
marketplace. Developing technology to compress digital signals will increasingly
permit the same broadcast, cable, or satellite channel to carry multiple video
and data services which could result in an expanded field of competing services.
Television broadcasters will continue to operate their current stations while
gradually building and operating digital facilities concurrently on separate
channels. This transition is expected to continue well into this decade.

The FCC's expanded television duopoly rule, which is defined in Regulatory
Matters on page 26, permits common ownership of two television stations without
regard to signal contour overlap provided they are located in separate markets
referred to as designated market areas (DMA's). In larger DMA's, common
ownership of up to two television stations is permitted so long as at least
eight independently owned and operating full-power television stations remain in
the market at the time of acquisition and at least one of the two commonly owned
stations is not among the top four-ranked stations in the market based on
audience share. In addition, without regard to numbers of remaining or
independently owned television stations, the FCC will permit television
duopolies within the same DMA so long as certain signal contours of the stations
involved do not overlap. Satellite stations that simply rebroadcast the
programming of a "parent" station will continue to be exempt from the duopoly
rule if located in the same DMA as the "parent" station. The duopoly rule also
applies to same-market local marketing agreements involving more than 15% of the
brokered station's program time, although current local marketing agreements
will be exempt from the television duopoly rule for a limited period of time of
either two or five years, depending on the date of the adoption of the local
marketing agreement. Further, the FCC may grant a waiver of the television
duopoly rule if one of the two television stations is a "failed" or "failing"
station, or the proposed transaction would result in the construction of a new
television station.

Following consummation of the Viacom/CBS merger, and exclusive of other
acquisitions, the combined company could potentially have duopolies in the
following six television markets: Philadelphia, Boston, Dallas, Miami, Detroit,
and Pittsburgh.

owned or leased 658 U.S. properties totaling 10,445,583 square feet of floor
area and 85 foreign locations totaling 668,808 square feet. Domestic locations
comprised approximately 94% of the total space. Leased facilities in the United
States accounted for approximately 35% of the total space occupied, while
facilities leased in foreign countries accounted for approximately 3% of the
total space occupied. No individual lease was material. The physical properties
described above are adequate and suitable, with an appropriate level of
utilization, for the conduct of our businesses in the future.

ITEM 3.  LEGAL PROCEEDINGS.

(a) On February 27, 1996, suit was brought against us in the United States
District Court (USDC) for the District of New Jersey by Public Service Electric
& Gas Company, PECO Energy Company, Atlantic City Electric Company, and Delaware
Power & Light Company, the owners of the Salem Generating Station. The suit
alleges counts under the Racketeer Influenced and Corrupt Organization Act
(RICO) for fraud, negligent misrepresentation, and breach of contract in
connection with our supply of steam generators and for service orders in 1993
and 1995 related to these steam generators. On October 1, 1997, we filed a
motion for summary judgment in this case. On November 6, 1998, the USDC granted
our motion for summary judgment based on the statute of limitations with respect
to plaintiffs' RICO claims and dismissed the RICO claims (with prejudice) and
plaintiffs' state claims, i.e., fraud, negligent misrepresentation and breach of
contract (without prejudice). Plaintiffs appealed the dismissal of the RICO
claims to the United States Court of Appeals for the Third Circuit (Third
Circuit) and have refiled their state claims in New Jersey Superior Court. On
January 27, 2000, a settlement was entered into resolving all claims associated
with this matter.

(b) In August 1988, the Pennsylvania Department of Environmental Resources
(PDER) filed a complaint against us alleging violations of the Pennsylvania
Clean Streams Law at our Gettysburg, Pennsylvania elevator plant. PDER requested
that the Environmental Hearing Board assess a penalty in the amount of $9
million. We denied these allegations. In November 1996, the Board assessed a
civil penalty of approximately $5.5 million. We appealed the Board's decision to
the Commonwealth Court. On January 2, 1998, the Commonwealth Court upheld the
Board's

                                                       CBS CORPORATION         7
<PAGE>   8

findings with respect to violations of the Pennsylvania Clean Streams Law but
not with respect to the amount of the penalty assessed. The Commonwealth Court
returned the matter to the Board for a reassessment of the penalty. Our
application for a rehearing before the Commonwealth Court was denied, as well as
our petition for a rehearing before the Pennsylvania Supreme Court. Oral
arguments before the Board were completed in February 1999. In March, 1999, the
Board reduced the penalty to approximately $3.3 million. In February, 2000, the
Commonwealth Court entered an order affirming the Board's decision to reduce the
penalty. On February 28, 2000, we paid this amount plus interest.

(c) We have been defending, in the USDC for the Western District of Pennsylvania
(the District Court), consolidated class and derivative actions and an
individual lawsuit brought by shareholders against CBS, Westinghouse Financial
Services, Inc. (WFSI) and Westinghouse Credit Corporation (WCC), previously
subsidiaries of CBS, and/or certain present and former directors and officers of
CBS, as well as other unrelated parties. Together, these actions allege various
federal securities law and common law violations arising out of alleged
misstatements or omissions contained in our public filings concerning the
financial condition of CBS, WFSI, and WCC in connection with a $975 million
charge to earnings announced on February 27, 1991; a public offering of our
common stock in May 1991; a $1,680 million charge to earnings announced on
October 7, 1991; and alleged misrepresentations regarding the adequacy of
internal controls at CBS, WFSI, and WCC. In July 1993, the court dismissed in
its entirety the derivative claim and dismissed most of the class action claims
with leave to replead certain claims in both actions. Both actions were
subsequently repled. On January 20, 1995, the District Court again dismissed the
derivative complaint in its entirety. Also on January 20, 1995, the court
dismissed class action claims but granted plaintiffs the right to replead
certain of the claims. Plaintiffs in the class action did not replead the claims
and on February 28, 1995, the court dismissed these claims in their entirety.
Plaintiffs in both the derivative and class action suits appealed the rulings
and dismissals of their claims by the District Court to the Third Circuit. (In
the derivative action, the Third Circuit affirmed the dismissal of this action
by the District Court.) In July 1996, the Third Circuit affirmed in part and
reversed in part the class action claims. Pursuant to this ruling, the class
action claims have been remanded to the District Court. In 1997, two similar
class action suits were brought against us in the District Court. These cases
allege similar facts and include the same defendants as in the previous class
action complaint filed in the District Court. In November 1997, the District
Court dismissed both of these actions. In March 1999, the attorneys who filed
the derivative action described herein filed a new derivative action based on
the same allegations previously asserted and dismissed. The parties to the class
actions and a derivative action reached an agreement to settle the matters for a
total cost of approximately $67 million, funded in large part by our liability
insurers. On October 19, 1999, the District Court approved the settlements and
our share was paid in 1999. The parties await the entry of a final order by the
District Court.

(d) On August 19, 1998, a former subsidiary of ours known as Westinghouse
International Services Corporation ("Westinghouse International") and others
commenced an arbitration proceeding (the "Arbitration") against WAK Orient Power
& Light Limited ("WAK"), a Pakistan corporation, in the International Court of
Arbitration of the International Chamber of Commerce (the "ICC"). The
Arbitration arose out of alleged breaches by WAK of an engineering, procurement
and construction contract (the "EPC Contract"), dated March 31, 1996, and
matters connected with the related project. WAK has denied these claims and has
filed counterclaims in the Arbitration. An arbitration proceeding on the merits
of this dispute was held on December 6, 1999. The parties await the decision.

On September 7, 1998, in contravention of its Arbitration obligations, WAK
commenced an action in a court in Lahore, Pakistan (the "Lahore Court")
reasserting its counterclaims from the Arbitration and now naming CBS,
Westinghouse Power Generation ("Westinghouse Power") and Westinghouse
International, and seeking 60 billion Pakistan rupees (approximately $1.3
billion). On May 7, 1999, without previously ruling on our and other defendants'
jurisdictional motions, the Lahore Court entered a default decree in the amount
of 60 billion Pakistan rupees (approximately $1.3 billion) against Westinghouse
Power and Westinghouse International and certain other defendants. The judgment
entered in the Lahore Court does not name CBS.

The above two proceedings relate to the sale of our Power Generation Business to
Siemens Power Generation Corporation (Buyer), which was completed on August 19,
1998.

Between May 26, 1999 and June 10, 1999, WAK purported to register the judgment
from Pakistan in the United States and execute upon the same against us and
others in the amount of approximately $1.5 billion. On June 14,

 8        CBS CORPORATION
<PAGE>   9

1999, we and Westinghouse International filed an action in the USDC for the
Eastern District of Pennsylvania (the "Federal Court") seeking, among other
things, a declaration that the parties' disputes are subject to Arbitration
under the authority of the ICC and enjoining WAK from registering, levying based
upon, or otherwise attempting to execute and enforce in any manner any levy or
any other execution action taken under the default judgment entered by the
Lahore Court. On June 16, 1999, the Federal Court entered an order restraining
WAK from registering or otherwise seeking to enforce any judgment based upon the
judgment entered by the Lahore Court. Also, on June 17, 1999, the Lahore High
Court, where the judgment is on appeal, entered an order suspending operation
and enforcement of the judgment entered by the Lahore Court pending a hearing.
On July 20, 1999, the Federal Court issued an order stating that its June 16,
1999 Order "remains in full force and effect until a further Order of this
Court." On September 15, 1999, a hearing was held before the Lahore High Court
on our appeal on the default judgment and plaintiff's appeal on the suspension
of enforcement of the judgment. A ruling has not yet been issued.

We believe that the Buyer has assumed all liabilities of CBS with respect to
this matter and that the Arbitration should take precedence over the Lahore
Court Action.

(e) On December 15, 1998, John F. Gritzer, along with six other individuals,
brought suit against CBS and the Westinghouse Pension Plan (the "Plan") in the
Federal District Court for the Western District of Pennsylvania (the "Court").
The suit alleges that we violated the terms of the Plan and breached our
fiduciary duty as Plan Administrator. Plaintiffs were employees of CBS until CBS
sold the division in which the plaintiffs were employed. Plaintiffs continued
their employment with the buyer of the business until plaintiffs were
involuntarily terminated in 1995. Plaintiff's claim that as a result of their
termination, they are entitled to special retirement benefits under the Plan by
virtue of the terms of the Plan and a reciprocal service agreement contained in
the asset purchase agreement between CBS and the buyer. On October 14, 1999, the
Court certified as a class all persons in the Plan who (i) were transferred to
another corporation in connection with a transfer of assets, (ii) were under a
purchase agreement that included a reciprocal service agreement, (iii) were
terminated through no fault of their own, and (iv) met the requisite age-service
combination for special early retirement pensions. We opposed class
certification. The Court declined to grant class status with respect to the
claims for breach of fiduciary duty. The parties have until June 30, 2000 to
complete discovery. No trial date has been set. A case involving similar facts
was recently tried before the Court. The Court in that case granted our motion
for a directed verdict.

(f) In September 1999, CBS and the individual members of the Board of Directors
were named as defendants in actions filed in Pennsylvania in the Philadelphia
County Court of Common Pleas Trial Division and in New York in the Supreme Court
of New York County of New York in connection with the contemplated merger of CBS
with Viacom. The action in Pennsylvania is entitled Rywell vs. CBS Corp. (filed
September 7, 1999) ("Rywell") and the action in New York is entitled Robert H.
Shenker Money Purchase Trust vs. Conrades (filed September 7, 1999) (the "New
York action"). The parties to the New York action stipulated on November 30,
1999, that the time to move against or answer the New York complaint would be
extended until 60 days after the plaintiffs served defendants with a copy of the
final disposition in Rywell. On November 30, 1999, plaintiffs served defendants
with a Consolidated Class Action Complaint in the Rywell action. In their
Consolidated Complaint, the plaintiffs, purportedly on behalf of themselves and
other shareholders of CBS, primarily assert that (i) the individual members of
CBS's Board of Directors have failed to act to maximize shareholder value,
including by failing to properly consider or solicit other bids for CBS, to hold
a public auction for CBS to conduct a market check, or to negotiate for an
adequate premium, and have acted according to their own personal interests,
rather than to their fiduciary obligations, (ii) the individual members of CBS's
Board of Directors have deprived plaintiff of an alleged informed right to vote
through misleading disclosures in the Proxy Statement sent the CBS shareholders
on November 26, 1999, and (iii) the merger of CBS with Viacom does not provide
sufficient value to CBS and its shareholders. Plaintiffs seek to enjoin the
merger with Viacom, unquantified damages, costs and disbursements, and other
remedies, and seek to have the defendants conduct an auction. We have filed
Preliminary Objections to Plaintiffs' complaint in the Philadelphia court.
Briefing on the Preliminary Objections has been completed. Oral argument on the
Preliminary Objections is scheduled for March 30, 2000.

(g) We are a defendant in numerous lawsuits claiming various asbestos-related
personal injuries, which allegedly occurred from use or inclusion of asbestos in
certain of our products supplied by its industrial businesses, generally in the
pre-1970 time period. Typically, these lawsuits are brought against multiple
defendants. We were neither a

                                                       CBS CORPORATION         9
<PAGE>   10

manufacturer nor a producer of asbestos and are oftentimes dismissed from these
lawsuits on the basis that we have no relationship to the products in question
or the claimant was not exposed to our products. At December 31, 1999, we had
approximately 121,000 unresolved claims pending against us. In court actions
that have been resolved, we have prevailed in many of the asbestos claims and
have resolved others through settlement. Furthermore, we have brought suit
against certain of our insurance carriers with respect to these asbestos claims.
Under the terms of a settlement agreement resulting from this suit, carriers
that have agreed to the settlement are now reimbursing us for a substantial
portion of our current costs and settlements associated with asbestos claims.

A number of the asbestos-related cases pending against us, including those in
Louisiana, Mississippi, Pennsylvania, and West Virginia, are consolidated or
purported class action cases. In consolidated cases, the claims of a group of
plaintiffs are tried together, and oftentimes limited findings with respect to
common issues of fact and punitive damages are decided with respect to a
representative grouping of plaintiffs and then applied to other individuals in
the group. However, for us to be liable for damages to any particular claimant,
that individual claimant must prove that he or she developed an asbestos-related
disease, that he or she was exposed to a product manufactured or supplied by us,
and that this exposure was a substantial factor in the development of the
disease.

Litigation is inherently uncertain and always difficult to predict. Substantial
damages are sought in certain of the foregoing matters and although we believe a
significant adverse judgment is unlikely, any such judgment could have a
material adverse effect on our results of operations for a quarter or a year.
However, based on our understanding and evaluation of the relevant facts and
circumstances, we believe that we have meritorious defenses to the litigation
described in items (c) through (g) above, and that we have adequately provided
for resolution of these matters. We believe that the litigation should not have
a material adverse effect on our financial condition.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

(a) A special meeting of shareholders of the Corporation was held on December
29, 1999.

(b) The following matter was submitted to a vote of the shareholders at the
special meeting with the following results: Adoption of the Agreement and Plan
of Merger, dated as of September 6, 1999, as amended and restated as of October
8, 1999 and as of November 23, 1999, among CBS Corporation, Viacom Inc. and
Viacom/CBS LLC was submitted to a vote of the shareholders at the special
meeting with the following results: 575,963,542 votes were cast for; 7,400,261
votes were cast against; and 2,644,747 abstentions were recorded in connection
with the adoption of this proposal.

MANAGEMENT'S DISCUSSION AND ANALYSIS

OVERVIEW

During 1999, we continued our record of growth and transformation. We have
divested our remaining industrial businesses, grown our core business operations
through strategic acquisitions, made investments in our newly created Internet
Group and effectively positioned CBS for continued future growth through our
pending merger with Viacom.

PENDING MERGER

On September 6, 1999, we entered into an agreement and plan of merger with
Viacom. Pursuant to this merger agreement, as amended, each share of CBS common
stock and each share of CBS Series B participating preferred stock issued and
outstanding immediately prior to the effective time of the merger will be
converted into the right to receive 1.085 shares of Viacom non-voting Class B
common stock and 1.085 shares of Viacom Series C preferred stock, respectively.
Each share of the CBS Series B participating preferred stock is entitled to
1,000 votes per share and is convertible at the option of the holder into 1,000
shares of CBS common stock. Each Viacom Series C preferred share will be
entitled to 100 votes per share and will be convertible into 1,000 shares of
Viacom non-voting Class B common stock at the option of the holder. On December
29, 1999, shareholders of both companies approved the merger. The merger is
contingent upon, among other things, the approvals of the Department of Justice
and the FCC. This transaction is expected to close in April 2000. As of December
31, 1999 merger related costs were not significant as they were largely
reimbursable by Viacom. We anticipate our share of additional merger related
costs for legal and investment banking fees to range from $8 million to $15
million. These costs will be expensed as incurred to the extent not reimbursable
by Viacom in accordance with the merger agreement.

See also Management's Discussion and Analysis--Regulatory Matters for potential
impacts of the merger.

ACQUISITIONS OF BUSINESSES

On December 7, 1999, Infinity Broadcasting, our majority-owned subsidiary
comprising our radio and outdoor advertising businesses, completed its
acquisition of Outdoor Systems. In connection with the acquisition, Infinity
Broadcasting issued $6.1 billion in Class A common stock in exchange for all of
the outstanding common stock of Outdoor Systems, and assumed $1.9 billion in
Outdoor Systems debt, at fair value and $670 million of Outdoor Systems stock
options. The closing of this transaction caused a reduction in our ownership
interest in Infinity Broadcasting from approximately 82% at December 31, 1998,
to approximately 65%, excluding the dilutive effect of stock options. Our voting
interest also declined from 96% at December 31, 1998, to approximately 90% at
December 31, 1999, as a result of the transaction. On December 6, 1999, CBS,
Infinity Broadcasting and Outdoor Systems (the Parties) entered into a final
judgment with the United States in connection with Infinity Broadcasting's
acquisition of Outdoor Systems. Under the terms of the final judgment, the
Parties must divest certain outdoor advertising properties principally in the
New York City area, all in accordance with the terms and conditions of the final
judgment. We do not view these divestitures as material to our business. Any
adjustments that may result from the disposal of Outdoor Systems' assets will be
offset against goodwill and any gains or losses on disposal of existing Infinity
Broadcasting assets will be recognized in operations.

On November 15, 1999, we completed our acquisition of King World for
approximately $2.7 billion which included $312 million for the fair value of
King World stock options assumed. Under the terms of the agreement reached on
March 31, 1999, King World shareholders received 0.81 shares of CBS common stock
for each share of outstanding King World common stock equating to approximately
58 million shares of CBS common stock with a market price of $40.81 per share.
King World is the distributor of a number of shows which include "The Oprah
Winfrey Show," "Wheel of Fortune," "Jeopardy!," and "Hollywood Squares."
Subsequent to December 31, 1999, we approved a proposed plan to integrate the
operations of King World with the existing CBS syndication business. See
Management's Discussion and Analysis--Consolidated Results of Operations--
Restructuring of Operations.

During 1999, we also acquired two CBS affiliate television stations in Texas.
KEYE-TV in Austin was acquired in August for approximately $160 million in cash.
KTVT-TV in Dallas-Fort Worth was acquired in October for $485 million of CBS
Series B participating preferred stock, or 10,142 preferred shares, and
approximately $3 million in cash.

                                                      CBS CORPORATION         13

INVESTMENTS IN INTERNET BASED COMPANIES

During 1999, we closed on a number of strategic investments focused on growing
our Internet based operations. These investments provided us with equity
ownership interests in Internet based companies in exchange for $45 million in
cash and $604 million in commitments to provide future advertising and promotion
time. In general, these advertising commitments will be met over a period of
seven years. In exchange for providing advertising and promotion time on its
media properties, Infinity Broadcasting will be provided an economic interest in
certain of these Internet investments.

As of December 31, 1999, we had investments in four publicly traded Internet
based companies: MarketWatch.com, Inc., Medscape Inc., SportsLine.com, Inc., and
Webvan Group, Inc. Other Internet investments as of December 31, 1999 include:
Jobs.com, Inc.; Loudeye Technologies, Inc.; Office.com, Inc.; Rx.com, Inc.;
StoreRunner, Inc.; Switchboard, Inc.; ThirdAge Media, Inc.; Women's Consumer
Network, LLC; and Wrenchead.com, Inc. Our investment in these nonconsolidated
investments in Internet based companies totaled $836 million at December 31,
1999. Our commitment to provide future advertising and promotion time is
non-cash in nature and has been recorded as deferred revenue in Other current
and Other noncurrent liabilities in the Consolidated Balance Sheet and totaled
$592 million at December 31, 1999. Barter revenue of $58 million was recognized
in our consolidated financial statements through December 31, 1999 as the
related advertising and promotion time was delivered. In addition, CBS.com, Inc.
is a wholly owned subsidiary of CBS and we have an ownership interest in iWon,
Inc., which is consolidated.

DISPOSAL OF INDUSTRIAL BUSINESSES

During 1999, we sold our Energy Systems, Government Operations, Machinery
Apparatus Operations and Plant Apparatus Division businesses for approximately
$250 million in cash plus the assumption by the buyers of liabilities,
commitments and obligations of approximately $970 million, all in accordance
with the terms of their respective agreements. With these sales, we have
disposed of essentially all of our industrial businesses. See notes 12 and 19 to
the financial statements.

USE OF EBITDA

We evaluate our operating performance based on several factors, of which the
primary financial measure is earnings before interest, taxes, minority interest,
equity losses, depreciation, and amortization (EBITDA). EBITDA eliminates the
effect of depreciation and amortization of tangible and intangible assets, most
of which were from acquisitions accounted for under the purchase method of
accounting. However, EBITDA should be considered in addition to, not as a
substitute for, operating earnings, net earnings, cash flows, and other measures
of financial performance reported in accordance with generally accepted
accounting principles. As EBITDA is not a measure of performance calculated in
accordance with generally accepted accounting principles, this measure may not
be comparable to similarly titled measures employed by other companies. EBITDA
differs from cash flows from operating activities primarily because it does not
consider changes in assets and liabilities from period to period, and it does
not include cash flows for interest and taxes.

CONSOLIDATED RESULTS OF OPERATIONS

REVENUES increased $568 million or 8% in 1999. This increase includes the impact
of the 1999 acquisitions of King World and Outdoor Systems, as well as the
inclusion of the full-year results of American Radio which was acquired in June
1998. Partially offsetting these increases were the absences of revenues from
the 1998 Winter Olympics and our 1998 divestitures of TeleNoticias and Eye on
People. On a comparable basis, which was determined as if the June 1998
acquisition of American Radio and any related divestitures and exchanges had
occurred on January 1, 1997 and excluding the impacts of the remaining
aforementioned items, 1999 revenues increased $733 million or 11% driven
primarily by advertising rate increases in our Infinity and Television segments.
In 1998, revenues increased $1,438 million or 27%. On a comparable basis,
excluding the impact of the 1998 Winter Olympics and the acquisition of American
Radio, 1998 revenues increased $610 million or 10%, reflecting strong growth in
the major radio markets as well as the inclusion of NFL American Football
Conference games in our television broadcasts in the second half of 1998.

OPERATING PROFIT increased $474 million or 98% in 1999. On a comparable basis,
as defined above, operating profit increased $504 million or 115%. This increase
resulted from higher advertising rates at our three largest segments and
management's continued focus on cost control. In 1998, operating profit
increased $229 million or 91%. The 1999 and 1998 results include special charges
of $2 million and $62 million, respectively, recognized for restructuring costs.
Due to television programming changes and

 14        CBS CORPORATION
<PAGE>   15

lower than expected severance costs in 1999, we reversed $26 million of the 1998
charge in 1999. In addition, 1999 operating profit includes a $7 million
recovery of a previously written off receivable in the Cable segment.

EBITDA increased $540 million or 49% in 1999. On a comparable basis, as defined
above, 1999 EBITDA increased $480 million or 44%. This increase resulted from
the higher advertising rates at our three largest segments and management's
continued focus on cost control. In 1998, EBITDA increased $324 million or 42%.
On a comparable basis, 1998 EBITDA increased $74 million or 8%. The 1999 and
1998 EBITDA include the special charges discussed above. In addition, 1999
EBITDA includes a special charge of $24 million recorded in other income related
to obligations of TeleNoticias. See Management's Discussion and
Analysis--Segment Results of Operations--Cable.

DEPRECIATION AND AMORTIZATION expense increased $98 million in 1999 and $126
million in 1998 due to significant levels of amortization of FCC licenses and
non-deductible goodwill arising from acquisitions. These costs will continue to
increase due to 1999 acquisitions.

RESIDUAL COSTS OF DISCONTINUED BUSINESSES primarily represent pension and
postretirement benefit costs for benefit plans retained by us covering inactive
and retired employees of previously divested industrial businesses. The pension
and postretirement benefit costs amounted to $169 million in 1999, $161 million
in 1998 and $142 million in 1997. Although our objective is to reduce this
earnings constraint over the next few years by fully funding the pension plan
and modifying postretirement benefits, management expects that these costs will
continue to negatively affect operating results in future years. Residual costs
increased $12 million in 1999 and $20 million in 1998. The increases resulted
from the retention of benefit obligations related to our 1999 divested
businesses as well as the full-year impact of those businesses divested in 1998
and 1997. Prior to the sales of these businesses, these costs were charged
against the liability for estimated loss on disposal included in the net
liabilities of Discontinued Operations. See note 12 to the financial statements.
Residual costs are expected to increase in 2000 by approximately $20 million due
to the full-year impact of 1999 divestitures. We are considering merging certain
qualified pension plans in the second quarter of 2000. If such merger is
completed as planned, the residual costs are expected to remain at 1999 levels.

OTHER INCOME, NET includes miscellaneous gains and losses on dispositions of
non-strategic assets and income from royalties. The decrease of $32 million in
1999 primarily relates to a $24 million charge recorded in 1999 for obligations
associated with TeleNoticias, a Spanish language cable network. See Management's
Discussion and Analysis--Business Segments--Cable. The decrease of $31 million
in 1998 primarily relates to a $24 million gain recorded in 1997 on the sale of
a partnership interest.

INTEREST EXPENSE declined $166 million in 1999 due to lower debt levels
resulting from the use of a significant portion of the cash proceeds received
from Infinity Broadcasting subsequent to its December 1998 IPO as repayment of
an intercompany note, to pay down CBS debt. In addition, during 1999 we
purchased certain debt securities prior to their scheduled maturity. The
decrease in interest expense of $16 million in 1998 was due to lower debt levels
and lower interest rates. The lower debt levels resulted from the use of cash
proceeds from divestitures to pay down debt and the purchase of certain debt
securities prior to their scheduled maturity, partially offset by debt assumed
in connection with our acquisition of American Radio in June 1998 totaling $1.3
billion.

In conjunction with our December 1999 acquisition of Outdoor Systems, we assumed
$1.9 billion in debt that will cause an increase in future interest expense.
This expected increase will be slightly offset by a reduction in interest
expense as a result of our recent debt extinguishments. See note 8 to the
financial statements. Future interest expense will also depend on our financing
strategy in future acquisitions, additional activity under the stock repurchase
programs, payment of postretirement benefits and retained liabilities of
discontinued businesses, as well as our overall performance. See note 20 to the
financial statements.

INCOME TAX EXPENSE was $461 million or 60% of pre-tax earnings for 1999 and $161
million or 104% of pre-tax earnings for 1998. The decrease in the effective tax
rate in 1999 primarily relates to increased operating earnings. In 1997, income
tax expense was $73 million despite a pre-tax loss of $59 million. The increase
in the income tax provision from 1997 to 1998 is primarily related to increased
operating earnings.

Our tax provision is significantly higher than the U.S. federal statutory tax
rate of 35% of pre-tax income. This higher tax provision results primarily from
the amortization of non-deductible goodwill associated with our media
acquisitions in recent years. Such

                                                      CBS CORPORATION         15
<PAGE>   16

permanent differences between book income and taxable income can significantly
impact our tax provision, and depending upon our level of income or loss and the
effect of non-recurring transactions, can cause dramatic fluctuations in our
effective tax rate. Non-deductible amortization is expected to increase as a
result of recent acquisitions. The components of our income tax provision
(benefit) are set forth in note 10 to the financial statements.

MINORITY INTEREST IN (INCOME) LOSS OF CONSOLIDATED SUBSIDIARIES increased $66
million to $72 million in 1999 and increased to $6 million in 1998 from a
benefit of $1 million in 1997. The increase in 1999 primarily resulted from the
full year impact of the December 1998 IPO of Infinity Broadcasting, our then
wholly-owned radio and outdoor advertising business. The IPO reduced our
ownership interest in Infinity Broadcasting to approximately 82%, excluding the
dilutive effect of stock options. This results in an offset in our consolidated
financial statements for the minority interest holder's proportionate interest
in post-IPO results of operations of Infinity Broadcasting. The closing of the
Outdoor Systems transaction in December 1999 caused a reduction in our ownership
interest in Infinity Broadcasting from approximately 82% at December 31, 1998 to
approximately 65% at December 31, 1999, excluding the dilutive effect of stock
options. As a result of this reduced ownership interest, minority interest in
(income) loss of consolidated subsidiaries is expected to increase. Future
minority interest expense will also depend on Infinity Broadcasting's financing
strategy for their future acquisitions and activity under their stock repurchase
program.

EQUITY LOSSES OF UNCONSOLIDATED AFFILIATED COMPANIES, NET OF INCOME TAXES are
related to our equity method of accounting investments in Internet based
companies. During the second half of 1999, we closed on a number of strategic
investments focused on growing our Internet based operations. We received an
equity interest in these Internet companies, in exchange for cash and future
advertising and promotion time on CBS and Infinity Broadcasting media
properties. We recognized our proportionate share of losses in these Internet
based companies and the amortization of the difference between our initial
investment in these entities and our proportionate ownership share in the
underlying net assets of these companies, which totaled $73 million, net of tax
benefit of $8 million. As of December 31, 1999, this difference of $596 million
is being amortized over a five-year period. See note 3 to the financial
statements. Future equity losses in Internet based companies are expected to
increase dramatically as the number of such equity investments expands and as
the full year impact of such losses is recognized. Additionally, these Internet
based companies will recognize marketing and promotional expenses as we deliver
the advertising and promotion time. Therefore, future losses for the Internet
based companies are expected to grow significantly, which in turn will increase
the non-cash equity losses for which we must recognize our proportionate share
and these losses are expected to be material to our consolidated results of
operations. Because of the expected growing significance of these non-cash
equity losses and amortization, we reported this amount as a separate line item
in the Consolidated Statement of Income.

The shares evidencing our equity ownership interests typically contain
restrictions that may limit our ability to sell or otherwise dispose of our
investments. The majority of these Internet based investments represent newly
formed enterprises that will require access to capital markets to fund their
future start-up losses. There can be no assurance that these companies will be
successful in raising the necessary capital to finance their operations, and we
have no obligation for future funding. These companies may also face intense
competition as more traditional "brick-and-mortar" companies respond to changes
in the market place, including launching their own Internet sites. As a result,
our future results of operations for a quarter or a year could be materially
affected by a non-cash write down in the carrying amount of these investments to
recognize an impairment loss due to an other than temporary decline in the value
of these investments. The advertising and promotion agreements entered into in
exchange for our equity interests in these investees contain termination
provisions in the event of failure or inability of the investee to perform.
Generally, pursuant to these termination provisions, we are released from
delivering any remaining unfulfilled advertising commitments. Upon termination
of the unfulfilled advertising and promotion commitments, the remaining deferred
revenue, if any, recorded as a liability will be reversed and recognized as a
component of equity losses of unconsolidated affiliated companies, net of income
taxes.

DISCONTINUED OPERATIONS, NET OF INCOME TAXES reflect the impact of our decision
to divest our remaining industrial businesses. During 1999, we closed on the
disposals of our Energy Systems, Government Operations, Machinery Apparatus
Operations and Plant Apparatus Division businesses. These disposals as well

 16        CBS CORPORATION
<PAGE>   17

as purchase price resolutions related to businesses previously disposed of
resulted in a gain on disposal of $628 million, net of income tax expense of
$294 million. In 1997, we recognized a gain on disposal of $871 million, net of
income tax expense of $779 million, related primarily to the sale of Thermo
King.

The Loss from Discontinued Operations includes the operating results of the
industrial businesses prior to adoption of the related disposal plans. For the
year ended December 31, 1997, this loss totaled $191 million, net of tax
benefits of $112 million. All operating results after the measurement date are
charged directly to the liability for estimated loss on disposal. Actual
operating results have not varied significantly from the amounts estimated. See
notes 12 and 19 to the financial statements.

EXTRAORDINARY LOSSES, NET OF INCOME TAXES in 1999 and 1998 primarily reflect the
write-off of debt issue costs in connection with the early extinguishment of
debt. During 1999, we repurchased, at market value, debt securities with a face
value of approximately $371 million. During 1998, we repurchased, at market
value, debt securities with a face value of approximately $298 million. As a
result of these early extinguishments and the write-off of debt issue costs, we
recognized extraordinary losses of $5 million in 1999, and $9 million in 1998,
net of tax benefits of $3 million and $6 million, respectively.

NET INCOME (LOSS) changed significantly year-over-year in 1999 and 1998 due
primarily to the absence in 1998 of the net gain on disposal of Discontinued
Operations. Income (loss) from Continuing Operations in 1999 reflects improved
results of $169 million to $157 million compared to a loss of $12 million. This
improvement was due to strong operating profits in our Infinity, Television and
Cable segments, as well as the lower interest expense. The decrease in the loss
from Continuing Operations in 1998 of $119 million was primarily due to the
increase in operating profit at our Infinity segment.

RESTRUCTURING OF OPERATIONS

We are committed to strengthening our businesses and improving our profitability
through restructuring actions ranging from changes in business strategies to
downsizing for process reengineering and productivity improvements. Cost
reduction initiatives are undertaken when the expected benefits are substantial
in relation to the cost of the programs and are realizable in the near term.
During the last three years, these efforts have resulted in charges of $2
million in 1999, $62 million in 1998 and $15 million in 1997, primarily at our
Television and Cable segments and our former and current corporate headquarters.
The majority of the restructuring costs involve the elimination of positions and
separation of employees. Due to television programming changes and lower than
expected severance costs in 1999, we reversed $26 million of the restructuring
reserve we established in 1998. Restructuring charges and the 1999 reversals are
primarily reflected in Operating expenses in the Consolidated Statement of
Income.

The following is a reconciliation of restructuring liability:

</TABLE>

The remaining $15 million principally relates to lease termination costs and to
a lesser extent employee separation costs. See note 13 to the financial
statements.

Subsequent to December 31, 1999, we approved a proposed plan to integrate the
newly acquired operations of King World with the existing CBS syndication
business to achieve synergies and eliminate redundant functions. The plan is
expected to result in a restructuring accrual in the range of $10 million to $14
million in 2000 and reflects primarily severance-related and relocation costs of
the acquired business. Restructuring costs related to the historical operating
activities of King World will increase goodwill and those costs incurred
relating to the existing CBS syndication business will be charged to operations.
The restructuring accrual includes severance-related and relocation costs of the
acquired business for approximately 70 employees in redundant functions and are
expected to be paid by year-end 2000. Terminations of employees are expected to
be completed by year-end 2000. The restructuring is expected to generate about
$13 million in savings in 2000, when fully realized.

INFINITY

Discussions below are provided on a comparable basis. Comparable basis was
determined as if the June 1998 acquisition of American Radio and any related
divestitures and exchanges of radio stations occurred on January 1, 1997. In
addition, comparable results exclude the December 1999 operating results of
Outdoor Systems.

The Infinity segment is comprised of owned and operated radio stations and
outdoor advertising businesses. Reported revenues in 1999 increased $556 million
or 29% over the prior year. The reported results include the full-year impact of
the June 1998 acquisition of American Radio and the one-month results of Outdoor
Systems. On a comparable basis, revenues increased 17%, primarily driven by
higher advertising rates at the majority of the radio stations and in the
outdoor advertising business. The higher advertising rates reflect increased
demand for advertising. Reported revenues in 1998 increased $413 million or 28%
over the prior year. The reported results include the impact of the acquisition
of American Radio. On a comparable basis, revenues increased 12%. This increase
reflects strong growth primarily in the top 15 radio markets and double-digit
growth at our outdoor advertising business in 1998. Radio revenues were 75% in
1999, 77% in 1998 and 75% in 1997 of total Infinity segment revenues. The
percentage of outdoor revenues is expected to increase in 2000 due to the
full-year impact of the December 1999 acquisition of Outdoor Systems.

Reported operating profit and EBITDA in 1999 increased $197 million or 36% and
$269 million or 34%, respectively, over the prior year. Reported operating
profit and EBITDA in 1998 increased $170 million or 46% and $223 million or 39%,
respectively, over the prior year. On a comparable basis, operating profit and
EBITDA in 1999 increased 34% and 23%, respectively, over the prior year. On a
comparable basis, operating profit and EBITDA in 1998 increased 36% and 21%,
respectively, over the prior year. These increases were driven by the higher
revenues discussed above and management's continued focus on cost control. The
higher growth rate in operating profit and EBITDA compared to the growth rate in
revenues results because a substantial portion of the Infinity segment's costs
are fixed.

As previously discussed, certain outdoor advertising assets are expected to be
divested in connection with Infinity Broadcasting's acquisition of Outdoor
Systems. See Management's Discussion and Analysis--Overview.

On March 3, 2000, Infinity Broadcasting entered into an asset purchase agreement
to acquire 18 radio stations, located in the top 50 markets, from Clear Channel
Communications for approximately $1.4 billion. This transaction is expected to
close by year-end 2000 and is subject to regulatory reviews and approvals. In
addition, on March 21, 2000, Infinity Broadcasting announced that it had entered
into an agreement to purchase Giraudy, one of France's largest outdoor
advertising companies, for approximately $425 million. This transaction is
expected to close mid-year 2000.

TELEVISION

The Television segment consists of three integrated operations: the CBS
television network; our owned and operated television stations; and our
television syndication operations. On November 15, 1999, we acquired the King
World syndication operations which have been reflected in our reported amounts.

Reported revenues in 1999 were level with those of the prior year. On a
comparable basis, excluding $103 million in revenues associated with the 1999
acquisition of King World and the impact of the 1998 Winter Olympics, revenues
would have increased by approximately 9%. This advance was driven by strong

 18        CBS CORPORATION
<PAGE>   19

up-front and scatter market advertising pricing, due in part to, increased
advertising demand across the industry. Approximately 80% of CBS Television's
1999-2000 season up-front inventory was sold at double-digit price increases,
subject to actual audience levels being achieved. Reported revenues in 1998
increased $780 million or 22% over 1997 primarily due to the broadcast of the
Winter Olympics during the first quarter of 1998 and the broadcasts of the 1998
NFL American Football Conference games during the third and fourth quarters.
Excluding the impact of the broadcast of the 1998 Winter Olympics and the NFL,
revenues would have remained level with the prior year. During 1998 CBS signed
an eight-year agreement, subject to rebid at the end of five years at the
discretion of the NFL, to broadcast American Football Conference games.

Reported operating profit and EBITDA increased $205 million or 140%, and $221
million or 57%, respectively in 1999. These increases are primarily attributable
to higher 1999 advertising pricing, partially offset by increased programming
costs, and the inclusion of operating profit of $6 million and EBITDA of $28
million associated with the recently completed King World acquisition. These
1999 increases also include a net benefit of $87 million resulting from the
absence of a 1998 special charge of $63 million recognized for restructuring
costs and asset impairment, the inclusion of a 1999 special charge of $2 million
recognized for employee terminations, and the reversal of $26 million of the
1998 special charge during 1999. This reversal was the result of television
programming changes and lower than expected severance costs. Partially
offsetting these 1999 improvements is the impact of the broadcast of the 1998
Winter Olympics. On a comparable basis, excluding the net effect of these items,
operating profit and EBITDA in 1999 would have increased approximately 170% and
55%, respectively. Reported operating profit and EBITDA in 1998 increased $27
million or 23%, and $46 million or 14%, respectively. These increases are due to
the broadcast of the 1998 Winter Olympics partially offset by a $63 million
restructuring and asset impairment charge recognized in the third quarter of
1998 and declines in profitability during the third and fourth quarters of 1998
due to higher costs for program rights. Excluding the net effect of these items,
operating profit was flat while EBITDA increased slightly compared to the prior
year. Comparable EBITDA margins were 13% in 1999 and 9% in both 1998 and 1997.

See Management's Discussion and Analysis--Consolidated Results of
Operations--Restructuring of Operations for discussion on the proposed plan to
integrate the operations of King World with the existing CBS syndication
business.

In the fourth quarter of 1999, we entered into a new agreement with the National
Collegiate Athletic Association (NCAA) for certain rights, including the right
to broadcast the NCAA Division I Men's Basketball Tournament and other
championship events. The contract provides for program rights payments of
approximately $6.2 billion over an eleven-year period commencing with the 2003
season. This new contract represents a significant increase in costs, more than
double the annual cost of the current eight-year contract of approximately $1.7
billion, but includes a significant expansion of our rights, including rights to
cable, digital broadcasting, rights to produce and develop the NCAA official
championship Internet site, rights to radio broadcasts, marketing, corporate
sponsorship, home video, merchandising and licensing. It is anticipated that we
will retain a substantial amount of the revenues generated from these rights in
accordance with the terms of the agreement. The new contract's impact on
operating profit, EBITDA and cash flows is significantly dependent upon a number
of factors, including the strength of the advertising market and our ability to
attract sufficient audience levels with respect to the NCAA programming.

CABLE

The Cable segment primarily consists of our cable networks, including TNN, CMT
and two regional sports networks. These networks are distributed by cable
television and other multichannel technologies. In December 1998 we divested Eye
on People and in November 1998 we finalized a joint venture agreement pursuant
to which 70% of the TeleNoticias cable channel business was sold. During 1999,
TeleNoticias filed for bankruptcy protection and subsequently is being
liquidated with certain obligations reverting back to us.

Reported revenues in 1999 increased $19 million or 3% over the prior year. This
increase was negatively impacted by the absence of revenues in 1999 related to
Eye on People and TeleNoticias which were divested in late 1998. On a comparable
basis, assuming the exclusion of the 1998 revenues of Eye on People and
TeleNoticias, revenues would have increased 8%. This growth reflects our ability
to increase advertising rates due to higher demand for

                                                      CBS CORPORATION         19

advertising across the industry. The increase in advertising has occurred
despite the continued increase in competition across the cable industry as the
growing number of channels available continues to provide more options to
viewers thereby placing more pressure on cable networks to attract and maintain
their audiences. Reported revenues in 1998 increased by $244 million or 81% over
the prior year. These increases were primarily attributable to the September 30,
1997 acquisition of TNN and CMT. We had previously owned a 33% interest in CMT.
On a comparable basis, assuming the acquisition of TNN and CMT occurred on
January 1, 1997, revenues for 1998 would have increased by approximately 10%.

Our rights to broadcast the NASCAR Winston Cup races were not renewed and expire
during the year 2000. Unless these broadcast rights are replaced with similar
revenue generating events, the positive historical trend in revenues may be
adversely affected.

Reported operating profit in 1999 increased $88 million or 176% as compared to
the prior year. On a comparable basis, assuming the exclusion of the 1998
operating losses of TeleNoticias and Eye on People, operating profit would have
increased 50% due to the increased advertising rates, a $7 million recovery of a
previously written off receivable and improved margins from restructuring and
other cost containment efforts initiated in 1998.

Reported EBITDA in 1999 increased $71 million or 48% over the prior year. On a
comparable basis, excluding the 1998 impact of TeleNoticias and Eye on People,
EBITDA increased 13%. This increase was driven by the improvement in operating
profit, partially offset by a special charge of $24 million in the second
quarter of 1999. This special charge was a direct result of the financial
difficulties which led TeleNoticias to file for bankruptcy protection under
Chapter 11, in the second quarter of 1999 and to ultimately be liquidated under
Chapter 7. Because of these financial difficulties, it is probable that certain
obligations that were assumed by the buyer will revert back to us. The $24
million special charge was recorded in Other income, net. Of the $24 million,
$11 million was paid in the second half of 1999 and the remaining balance is
expected to be satisfied over the next few years. On a comparable basis,
excluding the impact of this special charge and the recovery of the receivable,
EBITDA would have increased 22% and EBITDA margin would have increased to 42% in
1999 from 37% in 1998.

In 1998, reported operating profit increased $40 million and reported EBITDA
increased $75 million over last year. These increases were primarily
attributable to the September 30, 1997 acquisition of TNN and CMT, partially
offset by a 1997 gain on the sale of a partnership interest. On a comparable
basis, assuming the acquisition of TNN and CMT occurred on January 1, 1997, 1998
operating profit increased approximately 80%; this increase was attributable to
higher advertising sales. EBITDA on a comparable basis was flat compared to 1997
because of increased expenditures and a loss on disposal of a 70% interest in
TeleNoticias.

INTERNET GROUP

The Internet Group segment consists of our consolidated Internet based
companies, including CBS.com, Inc. and iWon, Inc., as well as our interests in
Internet based companies accounted for under the cost or equity methods of
accounting. However, the Internet Group segment results in the table on page 18
exclude the effect of changes in market value for our publicly traded cost
method investments and the results of operations for our equity method of
accounting Internet investments. Our proportionate share of losses and related
amortization expense in our equity method investments are reported separately as
Equity losses of unconsolidated affiliated companies, net of income taxes on the
Consolidated Statement of Income and discussed in Management's Discussion and
Analysis--Consolidated Results of Operations. The appreciation or depreciation
in the stock prices on our publicly traded cost method Internet investments are
recorded as a component of Accumulated other comprehensive loss in shareholders'
equity. The discussion below reflects the results of the consolidated Internet
based companies. See note 3 to financial statements.

Revenues of $13 million were primarily contributed by CBS.com, Inc. which began
operations in February 1998. Operating losses were $35 million with a negative
EBITDA of $37 million. The losses were driven by iWon, Inc.'s aggressive
advertising efforts to attract users to the web site through their cash
sweepstakes campaign. Approximately $19 million of the losses recognized relate
to advertising spots provided to consolidated Internet Group investments by our
Infinity, Television and Cable segments.

As discussed in Management's Discussion and Analysis--Overview, during 1999 we
closed on a number of strategic investments focused on growing our Internet
based operations. Future losses in these

 20        CBS CORPORATION
<PAGE>   21

companies are expected to increase dramatically due to their recognizing
marketing and promotional expenses as we deliver our advertising and promotion
time. Additionally, our losses will increase as the number of such investments
expand and as full-year results are recognized. We expect future non-cash equity
losses and amortization to be material to our consolidated results of
operations.

LIQUIDITY AND CAPITAL RESOURCES

OVERVIEW

During 1999, we generated $686 million in cash flow from operating activities
from our Continuing Operations, which represents a $391 million increase over
the prior year. These cash inflows were one of our major sources of liquidity
during the year, and were primarily utilized along with cash and cash
equivalents on hand at the beginning of the year to fund our stock repurchase
programs, repay debt, complete business acquisitions, and fund the operations of
our discontinued businesses through their dates of disposal. Additional 1999
sources of liquidity primarily include cash provided by business divestitures
and assets liquidations of $479 million and the cash and cash equivalents
acquired through the 1999 acquisitions of King World and Outdoor Systems which
were funded by the issuance of CBS and Infinity Broadcasting common stock,
respectively. Cash and cash equivalents and short-term investments acquired as
of the closing date for these companies totaled $573 million and $353 million,
respectively.

As previously stated, during 1999, we completed a number of acquisitions for
stock, cash and the assumptions of debt and stock options aggregating
approximately $12.2 billion and made certain equity investments in Internet
based businesses for cash and commitments to provide future advertising. In
general, future commitments to provide advertising will be met over a period of
seven years. The acquisitions and investments were primarily funded by the
issuance of 233 million shares of Class A common stock by Infinity Broadcasting,
the issuance of 58 million shares of CBS common stock, the issuance of
approximately 10 thousand shares of CBS Series B participating preferred stock,
the assumptions of $1.9 billion of debt at fair value and $982 million of stock
options as well as commitments to provide future advertising for $604 million.

In 1998, CBS formed Infinity Broadcasting, a new company comprising the Infinity
segment. In December 1998, Infinity Broadcasting sold 18% of its common stock in
an IPO, generating $3.2 billion of proceeds ($3.0 billion, net of offering
costs). CBS received the benefit of nearly 90% of the proceeds from the IPO
through the payment to CBS by Infinity Broadcasting of an intercompany note and
certain other intercompany transactions. A significant portion of these proceeds
were used by CBS to repay its revolving credit borrowings in 1998 and the
remainder was used to reacquire our common stock, repay other outstanding debt
and for general corporate purposes.

Because of the minority interest in Infinity Broadcasting following the stock
offering, certain modifications have been made to our cash management practices.
Of the $194 million in cash and cash equivalents presented on our Consolidated
Balance Sheet, CBS, as the parent company of Infinity Broadcasting, has direct
access to $122 million. The remaining cash balance is available to CBS if
Infinity Broadcasting were to pay a dividend on all of its common stock.
Infinity Broadcasting does not anticipate paying any dividends in the near term.
Cash generated by Infinity Broadcasting's operations is expected to be retained
by Infinity Broadcasting for use in its operations or for investing. Management
does not believe that this segregation of cash will materially impact our
liquidity.

Additionally, under the terms of an intercompany agreement and a tax sharing
agreement, Infinity Broadcasting reimburses CBS in cash for certain services
provided and its standalone income tax liability. Under the intercompany
agreement, we provide to Infinity Broadcasting a number of services, including
executive, human resources, legal, finance, information management, internal
audit, tax, and treasury services. The costs of these services are allocated
according to established methodologies determined on an annual basis.

With the completion of the Outdoor Systems acquisition, our ownership interest
in Infinity was reduced to approximately 65%, excluding the dilutive effect of
stock options, and therefore, after December 7, 1999, Infinity Broadcasting can
no longer be included in our consolidated U.S. federal and some state
consolidated tax returns. During 1999 cash taxes paid to CBS by Infinity
Broadcasting totaled $290 million while total net cash taxes paid by CBS,
excluding a prior year tax refund of $109 million, was $164 million. This
difference was due to the utilization of certain CBS deferred tax assets during
1999. During the next several years, consolidated cash taxes are expected to
increase as a result of the de-consolidation of Infinity Broadcasting from our
consolidated U.S. federal tax

                                                      CBS CORPORATION         21
<PAGE>   22

return since their taxable income can no longer be sheltered by our remaining
deferred tax assets.

We expect to have sufficient liquidity to meet our ordinary future business
needs. Sources of liquidity generally available to us include cash from
operations, proceeds from sales of investments and non-strategic assets, cash
and cash equivalents, short-term investments, availability of debt under our
credit facility, borrowings from other sources, including funds from capital
markets, and issuance of additional capital stock of CBS.

OPERATING ACTIVITIES

The operating activities of Continuing Operations provided cash of $686 million
during 1999 and $295 million during 1998. This increase in cash flow is
primarily attributable to our improved operating results. The sources of funds
identified as deferred and current income taxes are primarily related to the
utilization of certain CBS deferred tax assets and the receipt of $109 million
of prior year tax refunds in 1999. Cash paid for interest and taxes during 1999
also decreased significantly from 1998.

During 1998 operating activities of Continuing Operations provided $295 million
of cash while in 1997 used cash of $201 million. The $496 million improvement in
operating cash flows in 1998 reflects significant improvements in our results of
operations partially offset by the increase in customer receivables. The decline
in cash outflows of other assets and liabilities is primarily due to the timing
of payments in 1997.

Over the next several years it is likely that a portion of the future non-cash
advertising and promotion time provided by us in exchange for consolidated and
non-consolidated Internet based investments of $51 million and $592 million,
respectively, at December 31, 1999, will displace advertising inventory that
could otherwise be sold for cash. During 1999, $58 million in non-cash
advertising was provided to our nonconsolidated Internet investees and $19
million to our consolidated investees. In addition, as a result of our recent
investments in these Internet based companies, cash taxes paid are expected to
increase because CBS is contributing services in exchange for its ownership
interests. We are required to recognize taxable income equal to the fair value
of the shares received.

Cash outflows for operating activities are expected to increase as a result of
our NFL contract and our new NCAA contract. The new NCAA contract provides for
program rights payments of approximately $6.2 billion over an eleven-year period
commencing with the 2003 season. This new contract represents a significant
increase in costs, more than double the annual cost of the current eight-year
contract of approximately $1.7 billion, but includes a significant expansion of
our rights, including rights to cable, digital broadcasting, rights to produce
and develop the NCAA official championship Internet site, rights to radio
broadcasts, marketing, corporate sponsorship, home video, merchandising and
licensing. It is anticipated that we will retain a substantial amount of the
revenues generated from these rights in accordance with terms of the agreement.
Future liquidity may be significantly impacted by our ability to attract
sufficient audience levels with respect to the NFL and NCAA programming.

Cash contributed to our pension and postretirement plans totaled $366 million
during 1999 and $393 million during 1998. Our contribution level for 2000 is
expected to range between $210 million and $273 million and is consistent with
our goal to fully fund our qualified pension plans over the next several years.

The operating activities of Discontinued Operations used cash of $241 million
during 1999 compared to $331 million during 1998. The cash outflows during 1999
primarily reflect cash used in the operations of the Energy Systems and
Government Operations businesses through their date of disposition in March 1999
and resolution of certain working capital adjustments, while the cash outflows
during 1998 primarily reflect the cash used in the operations of its Power
Generation business through the date of its disposition in August 1998 as well
as the Energy Systems and Government Operations businesses. With the completion
of the sale of essentially all of our remaining industrial operations in 1998
and 1999, future operating cash flows of Discontinued Operations will consist
primarily of cash flows associated with certain remaining purchase price
adjustments, indemnification obligations and the liquidation of financial
services businesses. Cash flows associated with the financial services business,
including interest cost on debt of Discontinued Operations and the repayment of
that debt, will be satisfied through borrowings under the CBS revolver and cash
from continuing operations which the cash inflows from contractual liquidation
of the leasing portfolio are expected to be sufficient to repay, while cash
requirements to satisfy non-debt obligations of Discontinued Operations will
affect cash flows of Continuing Operations. Cash taxes arising from the
liquidation of our lease portfolio are expected to be

 22        CBS CORPORATION
<PAGE>   23

funded by cash from Continuing Operations over the next 15 years.

The operating activities of Discontinued Operations used $331 million of cash
during 1998 compared to $437 million of cash during 1997. The cash flows in 1998
and 1997 primarily reflect cash used in the operations of the Power Generation
and Energy Systems businesses.

We will continue to make payments for postretirement benefits, pensions,
divestiture costs and retained liabilities associated with the industrial
businesses. In addition, over the next several years we expect to resolve
certain tax contingencies related to the divestitures of our industrial
businesses which may increase cash taxes paid.

INVESTING ACTIVITIES

Net cash flows from investing activities during 1999 remained relatively
consistent with 1998, however a number of significant acquisitions and
divestitures occurred during each of these periods which ultimately drove the
results.

Investing cash inflows of $422 million during 1999 are primarily attributable to
$573 million of cash received in connection with the stock acquisitions of King
World and Outdoor Systems, and $479 million of cash received from business
divestitures and other asset liquidations which was partially offset by cash
outflows of $341 million for non-Internet business acquisitions, $45 million for
equity investments in Internet based companies acquired in 1999, $106 million
for other investments and assets as well as $171 million for capital spending.
Included in the 1999 capital spending is $16 million for consolidated Internet
investments. A portion of the cash paid for 1999 business acquisitions was
received from deposits held in acquisition trust. Business divestitures and
asset liquidations during 1999 primarily include the sale of certain of our
industrial businesses for approximately $250 million, the liquidation of our
leasing portfolio for $109 million, cash received from the divestiture of
several media properties totaling $59 million and proceeds of $47 million
received from the sale of short-term investments. Cash outflows during 1999 for
business acquisitions and investments primarily relate to the acquisition of
three radio stations, a television station, two transit advertising companies,
payments for Internet based and other investments, and the acquisition of a
radio dating service for a total of $492 million.

Cash flows provided from investing activities of $467 million during 1998 were
primarily related to the cash received from divestiture of discontinued
businesses, investments, and securities for approximately $2.2 billion,
partially offset by cash outflows associated with the cash payment to acquire
American Radio for $1.4 billion and 1998 capital expenditures for Continuing
Operations of $139 million. Cash flows provided by investing activities declined
$2.0 billion between 1998 and 1997. This decline in cash provided by investing
activities is a reflection of increased cash payments for business acquisitions
and investments and lower proceeds from divestitures in 1998. Cash inflows
during 1997 primarily relate to the sale of one of our industrial businesses for
$2.6 billion.

We have taken a number of actions which will have a direct impact on our cash
flows from investing activities. During 1999, we entered into a satellite
service arrangement that requires an advance payment of approximately $65
million, which will become payable in October 2000. As a result of the satellite
service payment and recent acquisitions, capital spending levels are expected to
increase between $90 million to $120 million over 1999 levels. We have committed
to contribute, upon request, approximately $55 million to a fund aimed at
providing minorities and women with access to capital to acquire and operate
radio and television stations. Over the next five years, based on our current
projections, we expect to spend approximately $100 million for equipment and
other capital assets to meet commitments for digital multichannel and high
definition transmission capability.

With the sale of essentially all the remaining industrial businesses, future
capital expenditures for Discontinued Operations will essentially be eliminated.

FINANCING ACTIVITIES

Total cash flows from financing activities dramatically shifted to a net cash
outflow during 1999 of $1.4 billion from a net cash inflow of $327 million
during 1998. A number of significant actions taken during each of these years
drove these results.

Total financing cash outflows of $1.4 billion during 1999 primarily reflect the
repurchase or redemption of certain outstanding debt for $683 million and the
purchase of 11.5 million shares of CBS common stock for $489 million, bringing
our total share repurchases to 39.8 million shares for $1,348 million. In
addition, Infinity Broadcasting purchased 17.6 million shares of

                                                      CBS CORPORATION         23
<PAGE>   24

its Class A common stock for $485 million. Partially offsetting these outflows
was cash generated of $266 million from stock issued for employee compensation
and benefit plans.

Cash inflows of $327 million during 1998, primarily relate to the net proceeds
of $3.0 billion received from Infinity Broadcasting's IPO, $493 million received
upon the issuance of Senior Notes due in 2005 and $351 million from CBS stock
issued for employee benefit plans. These 1998 cash inflows were partially offset
by cash outflows for net debt repayments totaling approximately $2.7 billion and
cash outflows for the purchase of 28.3 million shares of CBS's common stock
totaling $859 million. In February 1998, we announced that we would suspend
dividend payments on our common stock after payment of the March 1, 1998
dividend.

Cash used in 1999 and 1998 to repurchase and redeem debt as well as the purchase
of common stock were primarily financed by cash proceeds received from Infinity
Broadcasting subsequent to its December 1998 IPO, our cash flow from asset
dispositions and operations. Future purchases of common stock under CBS's $3.0
billion multi-year stock repurchase program and Infinity Broadcasting's $1.0
billion multi-year stock repurchase program ($500 million announced in June 1999
and an additional $500 million announced in January 2000) will be guided by
financial policies that are consistent with maintaining an investment grade
rating. Subsequent to December 31, 1999 through March 20, 2000, Infinity
Broadcasting purchased 4.7 million shares of its Class A common stock for $156
million and CBS purchased 3.5 million shares of its common stock for $200
million.

As discussed above, financing activities during 1998 provided cash of $327
million while cash used during 1997 totaled $2.0 billion. The increase in net
cash flows from financing activities is a reflection of the proceeds received
from Infinity Broadcasting subsequent to its December 1998 IPO. Cash outflows
during 1997 primarily include net debt repayments of $2.1 billion which was
funded primarily by the $2.6 billion in proceeds received on the sale of one of
our industrial businesses.

We are considering various alternatives with respect to our Internet strategy,
including pursuing a spin-off or creation of a tracking stock for our Internet
interests.

REVOLVING CREDIT FACILITY

Our August 1996 five-year revolving credit facility, as amended and restated in
December 1999, provides for $1.5 billion of credit available to CBS and our
subsidiaries excluding Infinity Broadcasting and its subsidiaries, and an
additional $1.5 billion of credit available for the exclusive use of Infinity
Broadcasting and its subsidiaries. Infinity Broadcasting's borrowings under this
facility are guaranteed by us.

The credit facility provides for short-term money market loans and revolver
borrowings. Borrowing rates under the facility are determined at the time of
each borrowing and are based generally on a floating rate index, the London
Interbank Offer Rate (LIBOR), plus a margin based on our senior unsecured debt
rating and leverage. The cost of the facility includes commitment fees, which
are based on the unutilized portion of the facility and vary with our debt
ratings. Revolver borrowings are classified as long-term. There are no
compensating balance requirements under the facility. At December 31, 1999,
Infinity Broadcasting had outstanding credit facility borrowings of $988
million, of which $38 million were short-term borrowings. These borrowings were
primarily used to pay down Outdoor Systems' credit facility in conjunction with
our acquisition of Outdoor Systems in December 1999.

Borrowing availability under the credit agreement is subject to compliance with
certain covenants, a maximum leverage ratio, minimum interest coverage ratio,
and minimum consolidated net worth. Certain of the financial covenants become
more restrictive over the term of the agreement. At December 31, 1999, we were
in compliance with the financial covenants.

As previously discussed, on March 3, 2000, Infinity Broadcasting entered into an
asset purchase agreement to acquire 18 radio stations from Clear Channel
Communications for approximately $1.4 billion. In addition, on March 21, 2000,
Infinity Broadcasting announced that it had entered into an agreement to
purchase Giraudy, one of France's largest outdoor advertising companies, for
approximately $425 million. Infinity Broadcasting plans to finance these
acquisitions with excess cash from operations and by executing a credit facility
which will increase their borrowing availability by $2.0 billion.

CONSOLIDATED BALANCE SHEET

During 1999, with the consummation of the acquisitions of King World, Outdoor
Systems, two television stations and various other media properties, we

 24        CBS CORPORATION
<PAGE>   25

continued our pursuit of identifying and obtaining accretive acquisitions. As a
result of these acquisitions both total assets and liabilities increased
dramatically. The increase in our assets resulted primarily from additional
intangible assets of $9.7 billion, property and equipment of $1.9 billion and an
increase of $811 million, year-over-year, in our investments in Internet based
companies. The increase in our liabilities resulted primarily from incremental
deferred tax liabilities of approximately $600 million recorded on identifiable
intangibles acquired, debt assumed of approximately $1.9 billion from Outdoor
Systems and deferred barter revenues of $592 million recorded in connection with
our 1999 investments in Internet based companies.

OTHER MATTERS

YEAR 2000

We have not experienced any significant disruptions to our financial or
operating activities caused by a failure of our computerized systems resulting
from Year 2000 issues. In addressing this matter we had undertaken efforts to
identify, modify or replace and then test systems to ensure Year 2000 compliance
by December 31, 1999. Total expenditures of $33 million were necessary to
achieve Year 2000 compliance, of which $18 million was incurred in 1999 and $15
million through December 31, 1998. Approximately 36% of these total expenditures
related to the replacement of existing systems. These costs were funded through
our cash flows from operations. All system modification costs were expensed as
incurred. The Year 2000 effort also included communications with all significant
third party suppliers and customers to determine the extent to which our systems
were vulnerable to those parties' failures to reach Year 2000 compliance. There
has been no significant loss of revenue, unanticipated costs or service
interruptions. Management does not expect any future failure of our third party
suppliers or customers to have a material adverse impact on our future business
operations or financial results.

QUANTITATIVE AND QUALITATIVE
DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk from changes in interest rates and foreign
exchange rates. To manage this exposure, we periodically enter into interest
rate and currency exchange agreements. We do not use financial instruments for
trading purposes and we are not a party to any leveraged derivatives.

At December 31, 1999, our total long-term debt from Continuing Operations was
$3,759 million, of which $2,799 million was fixed-rate debt. The fair value of
our fixed-rate debt was $2,831 million. A 1% decrease in interest rates would
increase the fair value of our fixed-rate debt by approximately $135 million.
Based on the balance of variable-rate debt at December 31, 1999, a 1% increase
in interest rates would increase annual interest expense by approximately $10
million.

At December 31, 1998, our total long-term debt from Continuing Operations was
$2,665 million, of which $2,634 million was fixed-rate debt. The fair value of
our fixed-rate debt was $2,805 million. A 1% decrease in interest rates would
increase the fair value of our fixed-rate debt by approximately $151 million.
Based on the balance of variable-rate debt at December 31, 1998, a 1% increase
in interest rates would have increased annual interest expense by approximately
$0.3 million.

At December 31, 1999, we had variable-to-fixed interest rate swap contracts
outstanding with a notional value of $775 million. The swap contracts expire in
less than three months. The fair value of these swaps at December 31, 1999 was
not material. At December 31, 1998, no interest rate swap contracts were
outstanding.

We continually monitor our economic exposure to changes in foreign exchange
rates and enter into foreign exchange forward contracts to hedge our transaction
exposure where appropriate. The notional amount of our foreign currency forward
contracts, which were hedging foreign currency denominated transactions at
year-end 1999, was $99 million and at year-end 1998 was $5 million. The majority
of these related to the Canadian Dollar. A 10% change in foreign exchange rates
across all currencies in our portfolio would not be material.

Our credit exposure under these agreements is limited to the cost of replacing
an agreement in the event of non-performance by our counterparty. To minimize
this risk, we select high credit quality counterparties.

For further information regarding our debt and financial instruments, see notes
8 and 9 to the financial statements.

ENVIRONMENTAL MATTERS

Compliance with federal, state, and local laws and regulations relating to the
discharge of pollutants into the environment, the disposal of hazardous wastes,
and other related activities affecting the environment have had and will
continue to have an impact on us. With regard to remedial actions under federal
and state

                                                      CBS CORPORATION         25
<PAGE>   26

Superfund laws, we had been named a potentially responsible party at numerous
sites located throughout the country. At many of these sites, we are either not
a responsible party or our site involvement is very limited or de minimis.
However, we may have varying degrees of cleanup responsibilities at
approximately 74 sites. It is difficult to estimate the timing and ultimate
costs to be incurred in the future due to uncertainties about the status of
laws, regulations, and technology; the adequacy of information available for
individual sites; the extended time periods over which site remediation occurs;
and the identification of new sites. The majority of the environmental matters
being addressed have arisen from past operation of our industrial businesses.
Although all the industrial businesses were divested by year-end 1999, we have
retained certain obligations relating to these past activities. At December 31,
1999, we had an accrued liability of $514 million reflected in Retained
liabilities of discontinued businesses and presented in Other current and Other
noncurrent liabilities in the Consolidated Balance Sheet. Of this amount, $397
million covers site investigation and remediation, and $117 million is for
post-closure and monitoring activities for approximately 74 sites for which
environmental responsibility remains with us. We anticipate that the majority of
expenditures for site investigation and remediation will occur during the next
five to ten years. Expenditures for post-closure and monitoring activities will
be made over periods up to 30 years. Should alternative remediation strategies
be selected, the costs related to these sites could differ from the amounts
currently accrued. We recognize changes in estimates as new remediation
requirements are defined or as more information becomes available.

We believe, based on our best estimate, that we have adequately provided for our
present environmental obligations and that complying with existing government
regulations will not materially impact our financial position, liquidity, or
results of operations.

REGULATORY MATTERS

Certain of our media acquisitions in recent years were subject to a number of
temporary conditional waivers of the FCC's rules respecting common ownership of
radio and television stations in the same market (formerly known as the
"one-to-a-market" rule). These waivers were granted subject to the outcome of
pending rulemaking in which a review of the one-to-a-market rule had been
proposed. Last August, the FCC revised the one-to-a-market rule and the rule
prohibiting common ownership of television stations with certain overlapping
signals (the "television duopoly" rule). The new radio/television
cross-ownership rule allows a single party to own in a market (a) up to two
television stations (if permitted by the television duopoly rule) and up to six
radio stations or (b) one television station and seven radio stations, in both
instances if sufficient market "voices," which include independently owned TV
and radio stations, daily newspapers and cable television, exist. The new
television duopoly rule allows the common ownership of television stations
located in different DMAs regardless of signal overlap. The new rule also
permits ownership of two television stations in the same market, if more than
eight independently owned television stations are licensed to the DMA and at
least one of the stations is not ranked among the top four in the DMA in
audience share. We have demonstrated compliance with the new rule in all markets
other than Los Angeles, Chicago and Dallas-Fort Worth, in each of which we own
attributable interests in eight radio stations and one television station, and
in Baltimore/Washington D.C. area where we have attributable interests in one
television station and (depending on how the FCC interprets its new rule) either
eight or eleven radio stations. As to those four markets, the temporary
conditional waivers will continue until 2004, at which time the FCC will review
its radio/television cross-ownership rule, and we will have an opportunity to
demonstrate that the continued ownership of our media assets in these markets
would serve the public interest.

In connection with the pending Viacom/CBS merger, the combined company may be
required to divest some of its broadcasting assets in order to obtain FCC
approval. The combined company would not be in compliance with current FCC
regulations in the following areas:

- - television stations held by both entities reach 41% of U.S. television
  households which exceeds the 35% maximum currently permitted by the FCC,

- - the combined company would not be permitted to continue the temporary
  conditional waivers of the radio/television cross-ownership rule until 2004,
  and with the addition of the Viacom television stations, the combined company
  may be required to divest as many as nine radio stations in certain markets,

- - the combined company would hold licenses for two television stations in six
  markets and may be required to divest a television station in one of these
  markets under the television duopoly rule,

 26        CBS CORPORATION
<PAGE>   27

- - it is likely that the combined company may also be required to divest
  additional broadcast stations in the event that the Commission's recent
  relaxation of its multiple ownership restrictions fails to become effective,
  or is stayed, reconsidered or modified by the FCC or by a court, and

- - the combined company may have to reduce or divest its interest in the United
  Paramount Network to comply with the rules limiting the common ownership of
  certain television networks.

In order to consummate the Viacom/CBS merger on an orderly and timely basis,
Viacom and CBS have requested that the companies be afforded a period of
twenty-four months to come into compliance with the 35% limitation and the dual
network rule, and six months to come into compliance with the radio/television
cross-ownership rule.

In April 1997, the FCC adopted a schedule under which broadcasters must build
digital television facilities and begin digital transmission. The FCC has not
expressly stated what the consequences would be if a licensee fails to meet the
adopted schedule. However, the Commission has indicated that it will grant an
extension of the applicable deadline where a broadcaster has been unable to
complete construction due to circumstances that are either unforeseeable or
beyond its control. Under the FCC's policy, two six-month extensions may be
granted by the FCC staff pursuant to delegated authority, but subsequent
extension requests must be referred to the full Commission.

Under the FCC's schedule, we were required to build digital facilities by May 1,
1999 for the eight stations we own in the ten largest television markets, and by
November 1, 1999 for the five television stations we own in television markets
11-30. We have begun transmitting digital broadcasts in New York, San Francisco,
Philadelphia, Los Angeles, Detroit and Dallas, all of which are top ten markets.
Applications for extension of construction permit have been granted with respect
to our stations in Minneapolis, Miami, Denver, and Baltimore. In addition, an
application for a second extension of construction permit has been granted in
Boston and one is pending in Chicago, both of which are top ten markets. An
application for a first extension remains pending in Pittsburgh. Our three
television stations in markets below the largest 30 must construct digital
facilities by May 1, 2002. Timely applications for construction permits have
been filed with respect to those stations.

All of our television and radio stations operate under licenses from the FCC,
which is empowered by the Communications Act of 1934, as amended, to, among
other things, license and regulate television and radio broadcasting stations.
The FCC has authority to grant or renew broadcast licenses for a maximum
statutory term of eight years if it determines that the "public convenience,
interest, or necessity" will be served thereby. During a specified period after
an application for renewal of a broadcast station license has been filed,
persons objecting to the license renewal application may file petitions to deny.
We have no reason to believe that the licenses will not be renewed in the
ordinary course, although there can be no assurance to that effect. The
non-renewal of a substantial number of or certain key licenses could have a
material adverse effect on us.

LEGAL MATTERS

We are defending a number of lawsuits on various matters. See note 19 to the
financial statements. We have provided for management's best estimate of costs
associated with resolution of these matters.

We are a defendant in numerous lawsuits claiming various asbestos-related
personal injuries. We were neither a manufacturer nor a producer of asbestos and
have often times been dismissed from these lawsuits on that basis. In court
actions resolved, we have prevailed in the majority of these claims and have
resolved others through settlement. We are reimbursed for a substantial portion
of our current costs and settlements through our insurance carriers. We have an
accrued liability for our share of estimated costs associated with outstanding
claims. This liability is reflected in Retained liabilities of discontinued
businesses and presented in Other current and Other noncurrent liabilities in
the Consolidated Balance Sheet. Factors considered in evaluating this litigation
include: claimed product involvement, alleged exposure to product, alleged
disease, validity of medical claims, number of resolved claims, available
insurance proceeds, and status of litigation in multiple jurisdictions. We have
not been able to reasonably estimate costs for unasserted asbestos claims.
However, we review asbestos claims on an ongoing basis and adjust our liability
as appropriate.

Litigation is inherently uncertain and always difficult to predict. Substantial
damages are sought in certain of our pending cases and, although we believe a
significant adverse judgment is unlikely, any such judgment could have a
material adverse effect on our results of operations for a quarter or a year.
However, based on our understanding and evaluation of the relevant facts and
circumstances, we believe we have

                                                      CBS CORPORATION         27
<PAGE>   28

meritorious defenses to the litigation and we have adequately provided for costs
arising from resolution of these matters. We believe that the litigation should
not have a material adverse effect on our financial condition.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 (SFAS 133), "Accounting for Derivative
Instruments and Hedging Activities." In June 1999, SFAS 133 was amended by SFAS
137, "Accounting for Derivative Instruments and Hedging Activities--Deferral of
Effective Date of FASB Statement No. 133," which delays the effective date for
adoption of SFAS No. 133 for one year, to fiscal years beginning after June 15,
2000. SFAS No. 133 standardizes the accounting for derivative instruments,
including certain derivative instruments embedded in other contracts, by
requiring that an entity recognize those items as assets or liabilities in the
statement of financial position and measure them at fair value. Our derivative
and hedging transactions are not material and it is anticipated that adoption of
this standard will not materially impact our financial results when adopted on
January 1, 2001.

INFORMATION RELATING TO FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K, including Item 7--"Management's Discussion and
Analysis of Financial Condition and Results of Operations," contains both
historical and forward-looking statements. All statements other than statements
of historical fact are, or may be deemed to be, forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. These
forward-looking statements are not based on historical facts but rather reflect
our current expectations concerning future results and events. The words
"believe," "expect," "intend," "plan," "anticipate," "likely," "will," and
similar expressions identify such forward-looking statements. These
forward-looking statements are subject to risks, uncertainties and other
factors, some of which are beyond our control, that could cause actual results
to differ materially from those forecast or anticipated in such forward-looking
statements.

Such risks, uncertainties and factors include, but are not limited to: the
timing, impact and other uncertainties related to acquisitions; our ability to
develop and/or acquire television programming and to attract and retain
advertisers; the impact of significant competition from both over-the-air
broadcast stations and programming alternatives such as cable television,
wireless cable, in-home satellite distribution services and pay-per-view and
home video entertainment services; the impact of new technologies including the
magnitude of equity losses and other uncertainties related to our Internet based
investments; changes in Federal Communications Commission regulations;
uncertainties related to certain litigation, environmental and other liabilities
associated with former industrial businesses; and such other competitive and
business risks as from time to time may be detailed in our Securities and
Exchange Commission reports.

Readers are cautioned not to place undue reliance on these forward-looking
statements which reflect management's view only as of the date of this Annual
Report on Form 10-K. The forward-looking statements included in this document
are made only as of the date of this document and we do not have any obligation
under Section 27A of the Securities Act of 1933, as amended, and Section 21E of
the Securities Exchange Act of 1934, as amended, to publicly update any
forward-looking statements to reflect subsequent events or circumstances.

REPORT OF MANAGEMENT

We have prepared the consolidated financial statements and related financial
information included in this report. Management has the primary responsibility
for the financial statements and other financial information and for
ascertaining that the data fairly reflect our financial position, results of
operations, and cash flows. The financial statements were prepared in accordance
with generally accepted accounting principles and necessarily include amounts
that are based on best estimates and judgments with appropriate consideration
given to materiality. Financial information included elsewhere in this report is
presented on a basis consistent with the financial statements.

We maintain a system of internal accounting controls, supported by adequate
documentation, to provide reasonable assurance that assets are safeguarded and
that our books and records reflect authorized transactions. Limitations exist in
any system of internal accounting controls based on the recognition that the
cost of the system should not exceed the benefits derived. We believe our system
of internal accounting controls, augmented by the corporate audit function,
appropriately balances the cost/benefit relationship.

The independent auditors provide an objective assessment of the degree to which
management meets its responsibility for fair financial reporting. They regularly
evaluate elements of the internal control structure and perform such tests and
procedures as they deem necessary to express an opinion on the fairness of the
financial statements.

The Board of Directors pursues its responsibility for our financial statements
through its Audit Review Committee composed of directors who are not officers or
employees of CBS. The Audit Review Committee meets regularly with the
independent auditors, management, and the corporate auditors. The independent
auditors and the corporate auditors have direct access to the Audit Review
Committee, with and without the presence of management representatives, to
discuss the scope and results of their audit work and their comments on the
adequacy of internal accounting controls and the quality of financial reporting.

We believe that our policies and procedures, including our system of internal
accounting controls, provide reasonable assurance that the financial statements
are prepared in accordance with the applicable securities laws and with a
corresponding standard of business conduct.

                                                      CBS CORPORATION         29

INDEPENDENT AUDITORS' REPORT

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF CBS CORPORATION

We have audited the accompanying consolidated balance sheet of CBS Corporation
and subsidiaries as of December 31, 1999, and 1998, and the related consolidated
statements of income and comprehensive income, cash flows, and shareholders'
equity for each of the years in the three year period ended December 31, 1999.
These consolidated financial statements are the responsibility of the
Corporation's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of CBS Corporation and
subsidiaries as of December 31, 1999, and 1998, and the results of their
operations and their cash flows for each of the years in the three year period
ended December 31, 1999, in conformity with generally accepted accounting
principles.

NOTES TO THE FINANCIAL STATEMENTS
(tabular dollars and shares in millions unless otherwise noted, except per share
amounts)

NOTE 1:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. On an
ongoing basis, management reviews its estimates, including those related to
litigation, environmental liabilities, program rights, Internet investments,
contracts, pensions, income taxes, and Discontinued Operations, based on
currently available information. Changes in facts and circumstances may result
in revised estimates.

Certain previously reported amounts have been reclassified to conform to the
1999 presentation.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of CBS Corporation
and its subsidiary companies. Intercompany accounts and transactions have been
eliminated. Investments in joint ventures and other companies we control are
consolidated in these financial statements. Investments in companies we do not
control but have the ability to exercise significant influence over operating
and financial policies are accounted for by the equity method. Equity method
investments are stated at their cost of acquisition adjusted for our equity in
undistributed net income (loss) since the date of acquisition. Investments that
we do not control and do not have the ability to exercise significant influence
over the operating and financial policies are accounted for by the cost method.
Cost method investments are carried at their cost of acquisition. Cost method
investments in publicly traded companies are subsequently marked-to-market with
unrealized gains and losses, net of income taxes, reported as a component of
Accumulated other comprehensive loss within shareholders' equity in the
Consolidated Balance Sheet.

REVENUE RECOGNITION

Revenues are primarily derived from the sale of advertising spots and are
recognized when spots are broadcast. We also receive revenues from syndication
on sales of owned programming, cable license fees from distribution of our cable
networks, and advertising revenues on the sale of outdoor advertising space and
the sale of banner advertisements on our web sites. Revenues from syndication
are recognized when the programming is available to telecast and certain other
conditions are met. Revenues from cable license fees are recorded in the period
that service is provided. Revenues on outdoor advertising space are recognized
proportionately over the contract term. Advertising revenues on banner contracts
are recognized over the period in which the advertisement is displayed.

ENVIRONMENTAL COSTS

We record liabilities when environmental assessments or remedial efforts are
probable and the costs can be reasonably estimated. Such estimates are adjusted
if necessary as new remediation requirements are defined or as more information
becomes available.

CASH AND CASH EQUIVALENTS

All investment securities with an original maturity of three months or less when
acquired are considered to be cash equivalents. All cash and temporary
investments are placed with high credit quality financial institutions and the
amount of credit exposure to any one financial institution is limited.

Following the December 1998 public stock offering of Infinity Broadcasting
Corporation (Infinity Broadcasting), our majority owned subsidiary, certain
modifications were made to our cash management practices. At December 31, 1999,
CBS, as the parent company of Infinity Broadcasting, has direct access to $122
million of the $194 million in cash and cash equivalents presented in the
Consolidated Balance Sheet. The remaining cash balance is available to us only
if Infinity Broadcasting pays a dividend on all of its common stock. Infinity
Broadcasting does not anticipate paying any dividends in the near term.

SHORT-TERM INVESTMENTS

Short-term investments are primarily comprised of available-for-sale securities
and reported at fair value, with unrealized gains and losses, net of income
taxes reported in Accumulated other comprehensive loss within shareholders'
equity in the Consolidated Balance Sheet. The cost of debt securities is
adjusted for the amortization of premiums and the accretion of

                                                      CBS CORPORATION         35
<PAGE>   36

discounts through maturity. Such amortization, interest income, realized gains
and losses, and declines in value judged to be other than temporary are included
in Other income, net in the Consolidated Statement of Income. The cost of
securities sold is based on specific identification.

PROGRAM RIGHTS

Costs incurred in connection with the production of programming or the purchase
of rights to programs, that are available to be broadcast within one year are
capitalized and classified as current assets while costs of programs to be
broadcast after one year are considered noncurrent and are classified as other
noncurrent assets in the Consolidated Balance Sheet. Program costs are amortized
as the respective programs are broadcast. Program rights are carried at the
lower of unamortized cost or net realizable value.

PROPERTY AND EQUIPMENT

Property and equipment assets are recorded at cost and depreciated over their
estimated useful lives. Depreciation is generally computed on the straight-line
method based on useful lives as follows:

<TABLE>
<CAPTION>
ASSET CATEGORY                          DEPRECIATION PERIOD
<S>                                     <C>
- -----------------------------------------------------------
Buildings and leasehold improvements    25 to 60 years
Advertising structures                  5 to 20 years
Land improvements                       20 years
Equipment and fixtures                  3 to 12 years
- -----------------------------------------------------------
</TABLE>

Leasehold improvements are amortized over the shorter of their useful life or
the term of the lease. Expenditures for additions and improvements are
capitalized, and costs for repairs and maintenance are charged to operations as
incurred.

INTANGIBLE ASSETS

Intangible assets primarily arise from the allocation of the purchase price of
businesses acquired. Amounts assigned to identifiable intangibles are based on
independent appraisals or internal estimates. Goodwill represents the residual
purchase price after allocation to all identifiable net assets including
identifiable intangibles. Identifiable intangible assets primarily include
Federal Communications Commission (FCC) licenses, which are limited as to
availability and have historically appreciated in value with the passage of
time, as well as cable license agreements, show contracts, distribution
networks, tradenames and transit franchise agreements. Intangible assets are
amortized using the straight-line method over their estimated lives ranging from
7 to 40 years.

RECOVERABILITY OF LONG-LIVED ASSETS

Intangible assets and all other long-lived assets are evaluated whenever events
and circumstances indicate that the remaining estimated useful life of the
assets may warrant revision or the remaining carrying value of such asset may
not be recoverable. When factors indicate that an asset should be evaluated for
possible impairment, we use an estimate of the related asset's undiscounted
future cash flows over the remaining life of that asset in measuring
recoverability. If identifiable cash flows are not available for the specific
asset, we evaluate recoverability of the specific business to which the asset
relates. If the undiscounted cash flows are less than the carrying value of the
asset, an impairment has in fact occurred. The carrying value of the asset is
written down to its estimated fair value and a charge is recognized in operating
expenses in the Consolidated Statement of Income. In the case of an equity
investment in an Internet based company, the impairment charge to reduce the
carrying value of the investment to its estimated fair value will be reflected
in Equity losses of unconsolidated affiliated companies, net of income taxes, in
the Consolidated Statement of Income. Estimated fair value is generally measured
by discounting estimated future cash flows or an active market price for the
asset.

DERIVATIVE FINANCIAL INSTRUMENTS

Derivative financial instruments are used, from time to time, to manage interest
rate and foreign currency exchange risks. We do not use financial instruments
for trading or speculative purposes and we are not a party to any leveraged
derivatives.

Under interest rate swap contracts, the differentials to be received or paid are
recognized as an adjustment to interest expense over the life of the contract.
Gains and losses on terminations of swap contracts are recognized as interest
expense when terminated in conjunction with the termination of the hedged
transaction, or to the extent that such hedged transaction remains outstanding,
deferred and amortized to interest expense over the remaining life of the hedged
transaction.

Forward exchange contracts are used to hedge the currency fluctuations on
transactions denominated in foreign currencies. Gains and losses on forward
exchange contracts and the offsetting losses and gains on hedged transactions
are recorded currently in Other

 36        CBS CORPORATION
<PAGE>   37

income, net in the Consolidated Statement of Income. Forward exchange contracts
are carried at fair value and are reflected in Other current assets or Other
current liabilities, as appropriate in the Consolidated Balance Sheet.

SUBSIDIARY STOCK TRANSACTIONS

Gains and losses on stock transactions by our subsidiaries and equity investees
are recognized directly in shareholders' equity through an increase or decrease
to capital in excess of par value in the period in which the transaction occurs.

STOCK-BASED COMPENSATION

We measure compensation cost for stock-based awards using the intrinsic value
based method of accounting prescribed by Accounting Principles Board (APB)
Opinion No. 25, "Accounting for Stock Issued to Employees." The pro forma net
income and pro forma earnings per share disclosures using the fair value based
method defined in Statement of Financial Accounting Standards (SFAS) No. 123,
"Accounting for Stock-Based Compensation," are provided in note 17 to the
financial statements.

NEW ACCOUNTING PRONOUNCEMENT

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133 (SFAS
133), "Accounting for Derivative Instruments and Hedging Activities." In June
1999, SFAS 133 was amended by SFAS 137, "Accounting for Derivative Instruments
and Hedging Activities - Deferral of Effective Date of FASB Statement No. 133,"
which delays the effective date for adoption of SFAS No. 133 for one year, to
fiscal years beginning after June 15, 2000. SFAS No. 133 standardizes the
accounting for derivative instruments, including certain derivative instruments
embedded in other contracts, by requiring that an entity recognize those items
as assets or liabilities in the statement of financial position and measure them
at fair value. Our derivative and hedging transactions are not material and it
is anticipated that adoption of this standard will not materially impact our
financial results when adopted on January 1, 2001.

NOTE 2:  MERGERS AND ACQUISITIONS

PENDING MERGER

On September 6, 1999, we entered into an agreement and plan of merger with
Viacom Inc. (Viacom). Pursuant to this merger agreement, as amended, each share
of CBS common stock and each share of CBS Series B participating preferred stock
issued and outstanding immediately prior to the effective time of the merger
will be converted into the right to receive 1.085 shares of Viacom non-voting
Class B common stock and 1.085 shares of Viacom Series C preferred stock,
respectively. Each share of the CBS Series B participating preferred stock is
entitled to 1,000 votes per share and is convertible at the option of the holder
into 1,000 shares of CBS common stock. Each share of Viacom Series C preferred
stock will be entitled to 100 votes per share. Each Viacom Series C preferred
share will be convertible into 1,000 shares of Viacom non-voting Class B common
stock at the option of the holder. The merger will be accounted for by the
purchase method of accounting. On December 29, 1999, shareholders of both
companies approved the merger. The merger is contingent upon, among other
things, the approvals of the Department of Justice and the FCC. This transaction
is expected to close in April 2000.

ACQUISITIONS OF BUSINESSES

During 1999, we completed the acquisitions of several businesses, the most
significant of which are discussed below, aggregating approximately $12.2
billion. These acquisitions were primarily funded by the issuance of 58 million
shares of CBS common stock, by the issuance of 233 million shares of Class A
common stock by Infinity Broadcasting, which led to the reduction of our
ownership interest, the issuance of 10,142 shares of CBS Series B participating
preferred stock, and the assumptions of $1.9 billion of debt at fair value and
$982 million of stock options. In addition, $341 million of cash was paid in
these transactions. These transactions primarily included acquisitions in
outdoor advertising businesses in the U.S. and internationally, television
syndication operations and television and radio stations. The acquisitions were
all accounted for under the purchase method. The purchase prices have been
preliminarily allocated based on the estimated fair value of the assets acquired
and liabilities assumed. The preliminary allocations were determined using
management's best estimates based on currently available information. We are in
the process of obtaining independent appraisals of the assets acquired and
expect this process to be complete by the end of the second quarter of 2000. As
additional information becomes available, these estimates will be adjusted and
the allocations finalized. The excess purchase prices over the preliminary
estimated fair values of the net assets acquired, of approximately $7.9 billion,
was allocated to goodwill.

                                                      CBS CORPORATION         37
<PAGE>   38

The results of operations of all acquisitions are included in the consolidated
financial statements from their respective dates of acquisition.

On December 7, 1999, Infinity Broadcasting completed its acquisition of Outdoor
Systems, Inc., (Outdoor Systems) for approximately $8.7 billion, which included
the assumption of $1.9 billion in debt, at fair value and $670 million of
Outdoor Systems stock options. The agreement to acquire Outdoor Systems was
reached May 27, 1999 and called for the exchange of each outstanding common
share of Outdoor Systems for 1.25 shares of Infinity Broadcasting Class A common
stock equating to approximately 233 million shares of common stock with a market
value of $26 per share. The closing of this transaction resulted in a reduction
in our ownership interest in Infinity Broadcasting from approximately 82% at
December 31, 1998 to approximately 65% at December 31, 1999, excluding the
dilutive effect of stock options. Our voting interest also declined from
approximately 96% at December 31, 1998 to approximately 90% at December 31, 1999
as a result of the transaction. The excess purchase price over the estimated
fair value of the net assets acquired of approximately $6.5 billion was
preliminarily allocated to goodwill and is being amortized on a straight-line
basis over 30 years. On December 6, 1999, CBS, Infinity Broadcasting and Outdoor
Systems (the Parties) entered into a final judgment with the United States in
connection with Infinity Broadcasting's acquisition of Outdoor Systems. Under
the terms of the final judgment, the Parties must divest certain outdoor
advertising properties principally in the New York City area, all in accordance
with the terms and conditions of the final judgment. We do not view these
divestitures as material to our business. Any adjustments that may result from
the disposal of Outdoor Systems' assets will be offset against goodwill and any
gains or losses on disposal of existing Infinity Broadcasting assets will be
recognized in operations.

On November 15, 1999, we completed our acquisition of King World Productions,
Inc. (King World) for approximately $2.7 billion which includes $312 million for
the estimated fair value of King World stock options assumed. Under the terms of
the agreement reached on March 31, 1999, King World shareholders received 0.81
shares of CBS common stock for each share of outstanding King World common stock
equating to approximately 58 million shares of CBS common stock with a market
price of $40.81 per share. The purchase price was preliminarily allocated to
assets acquired and liabilities assumed, identifiable intangibles of $1.1
billion and deferred taxes of $435 million with the excess purchase price over
the fair value of the net assets acquired of approximately $989 million
allocated to goodwill - which is being amortized on a straight-line basis over
15 years. Subsequent to December 31, 1999, we approved a proposed plan to
integrate the operations of King World with those of the existing CBS
syndication business. The plan is expected to result in a restructuring accrual
in the range of $10 million to $14 million in 2000. Restructuring costs related
to the historical operating activities of King World will increase goodwill and
those costs incurred relating to the existing CBS syndication business will be
charged to operations. See note 13 to the financial statements.

We also completed our acquisitions of two CBS affiliate television stations in
Texas: KEYE-TV in Austin closed on August 31, 1999 for $160 million in cash and
KTVT-TV in Dallas-Fort Worth closed on October 12, 1999 for $485 million of CBS
Series B participating preferred stock, or 10,142 preferred shares, and
approximately $3 million in cash. The purchase prices were preliminarily
allocated to FCC licenses of $478 million and to goodwill of $304 million. FCC
licenses and goodwill are amortized on a straight-line basis over 40 years.
Deferred tax liabilities of $143 million were recorded on the identifiable
intangibles.

During 1998, we completed acquisitions of radio stations and outdoor advertising
businesses aggregating approximately $2.8 billion for $1.5 billion in cash and
the assumption of debt of $1.3 billion. The most significant was our acquisition
of the radio broadcasting operations of American Radio Systems Corporation
(American Radio) on June 4, 1998, for $1.4 billion in cash plus the assumption
of debt with a fair value of approximately $1.3 billion. The acquisition was
accounted for under the purchase method. The purchase price was primarily
allocated to FCC licenses of $2.3 billion with the excess purchase price over
the estimated fair value of net assets acquired of approximately $825 million
allocated to goodwill and amortized on a straight-line basis over 40 years.
Deferred tax liabilities of $928 million were recorded on the identifiable
intangibles.

During 1997, we made acquisitions of cable networks, radio stations and transit
advertising assets aggregating $1.6 billion funded by the issuance of CBS common
stock and cash of $59 million. The most significant was our acquisition on
September 30, 1997, of The Nashville Network (TNN) and the remaining interest in
Country Music Television (CMT) from the

 38        CBS CORPORATION
<PAGE>   39

Gaylord Entertainment Company. We had previously owned a 33% interest in CMT.
The total purchase price for these cable networks of $1.6 billion was paid
through the issuance of 59 million shares of CBS's common stock. The acquisition
was accounted for under the purchase method. The purchase price was allocated to
cable license agreements of $506 million with the excess of the purchase price
over the estimated fair value of net assets acquired of $1.2 billion allocated
to goodwill and amortized on a straight-line basis over 40 years. Deferred tax
liabilities of $200 million were recorded on the identifiable intangibles. Prior
to the acquisition, we provided certain services to TNN and CMT for which we
received a commission.

PRO FORMA RESULTS
(unaudited)

The following unaudited pro forma information combines our consolidated results
of operations on a continuing basis with those of Outdoor Systems, King World
and American Radio as if these acquisitions had occurred on January 1, 1998. The
aggregate impact of other acquisitions was not material to our revenue, income
(loss) or income (loss) per share. The pro forma results give effect to certain
adjustments, including amortization expense from goodwill and other identifiable
intangible assets, interest expense from acquisition debt, the effect to
minority interest participation, all related income tax effects and the issuance
of additional shares.

synergies that might be achieved from the combined operations.

NOTE 3:  INVESTMENTS IN INTERNET BASED COMPANIES

During 1999, we closed on 12 investments focused on growing our Internet based
operations. These investments provided us with equity ownership interests in
Internet based companies primarily in exchange for commitments to provide future
advertising and promotion time. In general, these advertising commitments will
be met over a period of seven years. In exchange for providing advertising and
promotion time on its media properties, Infinity Broadcasting will be provided
an economic interest in certain of these Internet investments.

We obtained equity ownership interests during 1999, ranging from 22% to 50%, in
nine Internet based companies in exchange for $29 million in cash and $604
million in commitments to provide future advertising and promotion time. These
investments are accounted for under the equity method of accounting and comprise
the following: Jobs.com, Inc.; Medscape Inc.; Office.com, Inc.; Rx.com, Inc.;
StoreRunner, Inc.; Switchboard, Inc.; ThirdAge Media, Inc.; Women's Consumer
Network, LLC; and Wrenchead.com, Inc. In January 2000, we completed the
acquisition of a 30% ownership interest in Hollywood.com, Inc. (formerly Big
Entertainment, Inc.) which will also be accounted for as an equity method
investment in exchange for $100 million in future advertising and promotion time
and television content as well as cash of $5 million.

We obtained approximately 1% ownership interests in Webvan Group, Inc. and
Loudeye Technologies, Inc. (formerly encoding.com, Inc.). Both of these
investments are accounted for using the cost method of accounting.

We also acquired a majority ownership interest in iWon, Inc. in exchange for $6
million in cash, net of related transactions, and $70 million in future
advertising and promotion time, which is accounted for as a consolidated
subsidiary.

These 1999 Internet based investments added to our existing portfolio of
investments in Internet based companies: MarketWatch.com, Inc. our equity method
of accounting investment; SportsLine.com, Inc. our cost method of accounting
investment; and CBS.com, Inc. our consolidated Internet business.

Additionally, subsequent to December 31, 1999, we obtained a 35% equity
ownership interest in Content Commerce, L.P. in exchange for a commitment to
provide $40 million in future advertising and promotion time.

                                                      CBS CORPORATION         39
<PAGE>   40

The shares evidencing our equity ownership interest typically contain
restrictions that may limit our ability to sell or otherwise dispose of our
investments.

At the date of acquisition, for nonconsolidated equity investments in Internet
based companies we typically record our investment at an amount equal to the
cash consideration paid plus the fair value of the advertising and promotion
time to be provided. The associated obligation to provide future advertising and
promotion time is non-cash and is recorded as deferred revenue at an amount
equal to the fair value of the advertising and promotion time to be provided.
The December 31, 1999 investment balance of $836 million is reflected in Other
noncurrent assets and any related deferred revenue balance is presented in Other
current and Other noncurrent liabilities in the Consolidated Balance Sheet. See
note 7 to the financial statements. Deferred revenue is relieved and barter
revenue is recognized as the related advertising and promotion time is
delivered. Barter revenue of $58 million has been recognized on a consolidated
basis in 1999.

Where an agreement provides us with a licensing fee, based on a percentage of
gross revenues earned by the Internet based company in exchange for a license to
use the CBS name and logo, licensing revenue is recorded by us as the Internet
based company earns the revenues on which the license fees are based. No
significant license fee income has been recognized in 1999.

For equity method investments, a difference typically exists between our initial
investment and our proportionate share in the underlying net assets of these
companies. As of December 31, 1999, this difference of $596 million is being
amortized over a five-year period. Our 1999 proportionate share of losses in
these Internet based companies and the related amortization expense of our
initial basis difference totaled $73 million, net of income tax benefit of $8
million and represents the recording of operating results generally using a one
quarter lag. This non-cash amount is presented as Equity losses of
unconsolidated affiliated companies, net of income taxes in the Consolidated
Statement of Income.

The following summarized unaudited financial information of our Internet equity
investees reflects their results of operations for the first three quarters in
1999 and fourth quarter in 1998 or from inception.

Balance sheet information is as of September 30, 1999. For many of these
companies, 1998 information is not meaningful or not available since they were
newly formed.

</TABLE>

We had $199 million in cost basis Internet investments at December 31, 1999. The
1999 mark-to-market adjustments in fair value for the publicly traded cost
method investments in Internet based companies recognized through other
comprehensive income totaled a $67 million gain, net of deferred taxes.

The majority of our Internet based investments represent newly formed
enterprises that will require access to capital markets to fund their future
start-up losses. There can be no assurance that these companies will be
successful in raising the necessary capital to finance their operations, and we
have no obligation for future funding. These companies may also face intense
competition as more traditional "brick-and-mortar" companies respond to changes
in the market place, including launching their own Internet sites. Therefore,
our future results of operations for a quarter or a year could be materially
affected by a non-cash write down in the carrying amount of these investments to
recognize an impairment loss due to an other than temporary decline in the value
of these investments. This write down would be recognized in Equity losses of
unconsolidated affiliated companies, net of income taxes in the Consolidated
Statement of Income. The advertising and promotion agreements entered into in
exchange for our equity interest in these investees contain termination
provisions in the event of failure or inability of the investee to perform.
Generally, pursuant to these above termination provisions, we are released from
delivering any remaining unfulfilled advertising commitments. Upon termination
of the unfulfilled advertising and promotion commitments, the remaining deferred
revenue, if any, recorded as a liability will be reversed and recognized as an
adjustment to Equity losses of unconsolidated

 40        CBS CORPORATION
<PAGE>   41

affiliated companies, net of income taxes in the Consolidated Statement of
Income.

As of December 31, 1999, our investments include four publicly traded Internet
based companies: MarketWatch.com, Inc., Medscape Inc., SportsLine.com, Inc., and
Webvan Group, Inc. Based upon quoted market prices at December 31, 1999, the
aggregate market value of these investments would have exceeded their respective
aggregate carrying values by approximately $253 million.

NOTE 4:  INCOME (LOSS) PER COMMON SHARE--CONTINUING OPERATIONS

In 1997, we adopted SFAS No. 128, "Earnings per Share," which establishes
standards for computing and disclosing basic and diluted income (loss) per
common share.

The following is the computation of basic and diluted income (loss) per common
share from Continuing Operations:

Options to purchase shares of common stock of 15 million in 1998 and 27 million
in 1997 were excluded in the computation of income (loss) per common
share-diluted, because their inclusion would be anti-dilutive. Shares of common
stock issuable under deferred compensation arrangements of 3 million in 1999, 5
million in 1998 and 6 million in 1997 were also excluded in the computation of
income (loss) per common share-diluted, because their inclusion would be
anti-dilutive. See note 17 to the financial statements for additional
information on stock options.

At December 31, 1999, we had $38 million of short-term borrowings outstanding
that primarily related to short-term money market loans under our credit
facility. The weighted average interest rate on these borrowings was 7.1%. No
short-term borrowings were outstanding at December 31, 1998.

In connection with the acquisition of Outdoor Systems in December 1999, Infinity
Broadcasting assumed Outdoor Systems' debt with a fair value of $1.9 billion. At
the time of acquisition, approximately $1.1 billion was outstanding under
Outdoor Systems' senior credit facility which was repaid in conjunction with the
acquisition, primarily with borrowings under Infinity Broadcasting's revolving
credit agreement. The remaining debt assumed consisted of 8 7/8% senior
subordinated notes due 2007 and 9 3/8% senior subordinated notes due 2006. These
notes were recorded at their respective fair values at the date of acquisition.
The indentures related to these notes contain covenants applicable to Outdoor
Systems including, among others, limitations on sales of assets, dividend
payments, and future indebtedness. Under the most restrictive covenants of these
indentures, approximately $440 million of Outdoor Systems' net assets at
December 31, 1999 are restricted. This, in turn, limits the ability of Outdoor
Systems to pay dividends. As a result of the change in control related to the
acquisition of Outdoor Systems by Infinity Broadcasting, an offer to purchase
the outstanding notes was made in January 2000. The offer expired in February
2000 and $6 million of the notes were redeemed.

The 9 3/4% senior notes due 2005, the 9% senior subordinated notes due 2006, the
11 3/8% subordinated exchange debentures due 2009, and the 7% convertible
subordinated debentures due 2011 are related to our June 1998 acquisition of
American Radio. The indentures related to these notes and debentures contain
covenants applicable to American Radio including, among others, limitations on
sales of assets, dividend payments, and future indebtedness. Under the most
restrictive covenants of these indentures, approximately $1.2 billion of
American Radio's net assets at December 31, 1999 are restricted. This, in turn,
limits the ability of American Radio to pay dividends.

Our August 1996 five-year revolving credit facility, as amended and restated in
December 1999, provides for $1.5 billion of credit available to CBS and our
subsidiaries excluding Infinity Broadcasting and its subsidiaries, and an
additional $1.5 billion of credit available for the exclusive use of Infinity
Broadcasting and its subsidiaries. Infinity Broadcasting's borrowings under this
facility are guaranteed by us. The credit facility provides for short-term money
market loans and revolver borrowings. Borrowing rates under the facility are
determined at the time of each borrowing and are based generally on a floating
rate index, the London Interbank Offer Rate (LIBOR), plus a margin based on our
senior unsecured debt rating and leverage. The cost of the facility includes
commitment fees, which are based on the unutilized portion of the facility and
vary with our debt ratings. Revolver

 42        CBS CORPORATION

borrowings are classified as long-term. There are no compensating balance
requirements under the facility. Borrowing availability under the credit
agreement is subject to compliance with certain covenants, a maximum leverage
ratio, minimum interest coverage ratio, and minimum consolidated net worth.
Certain of the financial covenants become more restrictive over the term of the
agreement. At December 31, 1999, we were in compliance with the financial
covenants.

During 1999, we repurchased, at market value, debt securities with a face value
of approximately $371 million. During 1998, we repurchased, at market value,
debt securities with a face value of approximately $298 million. As a result of
these early extinguishments and the write-off of debt issue costs, we recognized
extraordinary losses of $5 million in 1999, and $9 million in 1998, net of tax
benefits of $3 million and $6 million, respectively.

The 8 7/8% notes due 2014 are redeemable at 100% of principal plus accrued
interest at the election of the holder on June 14, 2004. We may redeem the notes
only if the total outstanding principal is $10 million or less. We also have the
option to redeem certain debentures and notes at specified redemption prices
plus accrued interest prior to their scheduled maturity dates, as set forth in
the table below.

NOTE 9:  FINANCIAL INSTRUMENTS

The estimated fair value of financial instruments is determined using the best
available market information and appropriate valuation methodologies. However,
considerable judgment is necessary in interpreting market data to develop the
estimates of fair value.

Accordingly, the estimates presented are not necessarily indicative of the
amounts that we could realize in a current market exchange or the value that
ultimately will be realized upon maturity or disposition. Additionally, because
of the variety of valuation techniques permitted under SFAS No. 107,
"Disclosures about Fair Values of Financial Instruments," comparability of fair
values among entities may not be meaningful. The use of different market
assumptions or estimation methodologies may have a material effect on the
estimated fair value amounts.

SHORT-TERM INSTRUMENTS

The fair values of cash and cash equivalents, short-term investments, short-term
debt and current maturities of long-term debt approximated the carrying values
at December 31, 1999 and 1998 because of the short-term nature of these
instruments.

INVESTMENTS IN MARKETABLE SECURITIES

The fair value of investments in marketable securities is based on quoted market
prices. Fair value approximated the carrying value at December 31, 1999 and
1998, as these investments are marked-to-market.

NONCURRENT CUSTOMER AND OTHER RECEIVABLES

The fair values of noncurrent customer and other receivables are estimated by
discounting the expected future cash flows at interest rates commensurate with
the creditworthiness of the customer or third party. The fair values
approximated the carrying values at December 31, 1999 and 1998.

LONG-TERM DEBT

The fair value of long-term debt is estimated using quoted market prices or
discounted cash flow methods based on our current borrowing rates for similar
types of borrowing arrangements with comparable terms and maturities. The
carrying values and fair values were $3,753 million and $3,785 million,
respectively, at December 31, 1999 and $2,506 million and $2,674 million,
respectively, at December 31, 1998.

FOREIGN CURRENCY EXCHANGE CONTRACTS

We are subject to risks associated with changes in foreign currency exchange
rates that affect the value of transactions denominated in foreign currencies.
Foreign exchange forward contracts are used to manage certain of these risks,
primarily with respect to the Canadian dollar. These contracts generally mature
in less than six months. At December 31, 1999 and 1998, the notional amount of
forward contracts was $99 million and $5 million, respectively. The increase in
1999 relates to contracts to hedge exposures at Outdoor Systems which was
acquired in December 1999. Foreign exchange forward contracts are carried on the
balance sheet at fair value based on quoted market prices to terminate the
contracts. At December 31, 1999 and 1998, the fair value of these contracts was
not material.

                                                      CBS CORPORATION         43
<PAGE>   44

INTEREST RATE SWAP CONTRACTS

At December 31, 1999, we had variable-to-fixed interest rate swap contracts
outstanding with a notional value of $775 million. The swap contracts expire in
less than three months. The fair value of these swaps at December 31, 1999 was
not material. At December 31, 1998, no interest rate swap contracts were
outstanding.

CREDIT CONSIDERATIONS

Our credit exposure under foreign currency exchange contracts and interest rate
swap contracts is limited to the cost of replacing a contract in the event of
non-performance by our counterparties. To minimize this risk, we select high
credit quality counterparties. We do not anticipate non-performance by our
counterparties.

LETTERS OF CREDIT

Outstanding letters of credit totaled $176 million in 1999 and $148 million in
1998. Management does not believe it is practicable to estimate the fair value
of these financial instruments and does not expect any material losses from
their resolution since performance is not likely to be required.

The valuation allowance for deferred tax assets primarily reflects foreign tax
credits which may not be utilized as a result of the reduction in foreign source
income caused by the divestiture of foreign subsidiaries

principally related to Discontinued Operations. We believe we will have
sufficient future taxable income to make it more likely than not that the net
deferred tax asset will be realized.

At December 31, 1999, CBS and Infinity Broadcasting had alternative minimum tax
credit carryfowards of $192 million and $14 million, respectively, both having
no expiration dates. In addition, CBS had $32 million of foreign tax credit
carryfowards that expire through 2003.

Infinity Broadcasting also has recognized a deferred tax asset for net operating
loss carryforwards of $91 million primarily related to Mexican operating loss
benefits that expire in 2008. The Infinity Broadcasting net operating loss
carryforwards arose from the operations of Outdoor Systems prior to the
acquisition by Infinity Broadcasting. We believe that our taxable income will
more likely than not be sufficient to utilize the net operating loss
carryforwards prior to their expiration.

Income Tax Expense (Benefit) from Continuing Operations is as follows:

The foreign portion of income or loss from Continuing Operations before income
taxes and minority interest in income of consolidated subsidiaries consisted of
income of $35 million in 1999, $26 million in 1998 and $13 million in 1997. Such
income consists of profits and losses generated from foreign operations that can
be subject to both U.S. and foreign income taxes.

The federal income tax returns are settled through the year ended December 31,
1989. We have reached an agreement with the Internal Revenue Service regarding
certain issues for the years 1990 through 1992 and a tentative agreement for
1993. We believe adequate provisions for taxes have been made through December
31, 1999.

NOTE 11:  PENSIONS, POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS

In 1998, we adopted SFAS 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits." SFAS 132 standardized the disclosures of pensions and
other postretirement benefits into a combined format but did not change the
accounting for these benefits. We have a number of defined benefit pension and
other postretirement benefit plans.

A one percentage point increase or decrease in the assumed health care cost
trend rates would have an approximate effect of a $2 million increase or
decrease on the total of service and interest cost components and a $26 million
increase or decrease on the postretirement benefit obligation.

We also participate in various multi-employer, union-administered defined
benefit plans that cover certain broadcast employees. Contributions for pension
and other postretirement benefits to these multi-employer plans were $16 million
in 1999, $14 million in 1998 and $13 million in 1997.

POSTEMPLOYMENT BENEFITS

We provide certain postemployment benefits to former or inactive employees and
their dependents during the time period following employment but before
retirement. Our liability for postemployment benefits totaled

<PAGE>   47

$34 million in 1999 and $55 million in 1998. The portion of this liability
included in the net assets of Discontinued Operations was $26 million in 1998.

NOTE 12:  DISCONTINUED OPERATIONS

In recent years, we adopted various disposal plans that, in the aggregate,
provide for the disposal of all of our industrial and financial services
businesses. The assets and liabilities and the results of operations for these
businesses are classified as Discontinued Operations for all periods presented.
Certain environmental, litigation and other liabilities associated with the
industrial businesses were not assumed by other parties in the divestiture
transactions. These liabilities were retained by CBS and reported in Retained
liabilities of discontinued businesses in the Consolidated Balance Sheet. See
notes 7 and 19 to the financial statements.

During 1999, we closed on the previously announced sales of our Energy Systems,
Government Operations, Machinery Apparatus Operations and Plant Apparatus
Division businesses for approximately $250 million in cash plus the assumption
by the buyers of liabilities, commitments and obligations totaling approximately
$970 million, all in accordance with the terms of their respective agreements.
These disposals, as well as purchase price resolutions related to businesses
previously disposed, resulted in a gain of $628 million, net of income tax
expense of $294 million.

During 1998 and 1997, we sold several businesses as well as certain securities
and other assets in connection with our disposal plans. The most significant of
these disposals were the 1998 sale of the Power Generation business for $1.2
billion in cash and the 1997 sale of Thermo King for $2.6 billion in cash. In
1997, we recognized a gain of $871 million, net of income tax expense of $779
million, primarily related to the sale of Thermo King.

</TABLE>

Total assets of Discontinued Operations at December 31, 1999 consist primarily
of portfolio investments that remain from the financial services business. These
investments totaled $555 million and $642 million at December 31, 1999 and 1998.
The portfolio investments consist of direct financing and leveraged leases and
are generally expected to liquidate in accordance with contractual terms through
2015. At December 31, 1999 and 1998, 84% and 81% of the portfolio investments
related to aircrafts while the remainder primarily related to cogeneration
facilities. Approximately $281 million of the portfolio investment balance in
1999 relates to the estimated residual value of leased assets.

Total liabilities of Discontinued Operations consist primarily of the estimated
loss on disposal of $623 million in 1999 and $1,309 million in 1998. At December
31, 1999, the estimated loss on disposal primarily includes the portfolio
investments' estimated results of operations through the expected date of
liquidation, unresolved purchase price adjustments, costs to dispose of surplus
property held for sale and certain contingencies related to the divestiture of
the industrial businesses. Satisfaction of these liabilities is expected to
occur over the next several years. During 1999, we resolved several purchase
price adjustments resulting in a reduction to the estimated loss on disposal. We
believe the liability for estimated loss on disposal at December 31, 1999 is
adequate to cover liquidation of the remaining assets and liabilities of
Discontinued Operations, resolution of unresolved purchase price adjustments and
other related costs and contingencies.

Liabilities of Discontinued Operations also include portfolio related debt of
$415 million and $428 million at December 31, 1999 and 1998, as follows:

SETTLEMENT AND ENVIRONMENTAL LIABILITIES

Prior to the disposition of our Energy Systems business in 1999, we had been
defending various lawsuits claiming damages in connection with certain steam
generators sold by the Energy Systems business. Settlement agreements had been
entered into resolving a number of the litigation claims, which generally
required that we provide certain products and services at prices discounted at
varying rates. In addition, we

                                                      CBS CORPORATION         47
<PAGE>   48

were a party to three tolling agreements with utilities or utility plant owners'
groups that asserted steam generator claims. The obligations associated with
these previous settlement agreements, the tolling agreements and such litigation
were assumed by the buyer of the Energy Systems business, all in accordance with
the terms of the divestiture agreement.

RESULTS OF OPERATIONS

Summarized in the following table are the operating results of Discontinued
Operations, primarily related to industrial businesses, after the measurement
date charged directly to the liability for estimated loss on disposal.

</TABLE>

The loss from Discontinued Operations reflected in the Consolidated Statement of
Income includes the operating results of the discontinued businesses prior to
adoption of the related disposal plans. For the year ended December 31, 1997,
this loss totaled $191 million, net of tax benefits of $112 million. Sales of
Discontinued Operations in 1997 prior to adoption of the related disposal plans
totaled $2,950 million.

CASH FLOWS

Cash proceeds from the sale or liquidation of all assets of Discontinued
Operations except for portfolio investments, as well as cash requirements to
satisfy non-debt obligations of Discontinued Operations will affect cash flows
of Continuing Operations. Cash flows associated with the financial services
business, including interest cost on debt of Discontinued Operations and the
repayment of that debt, will be satisfied through borrowings under the CBS
revolver and cash from continuing operations, which the cash inflows from
contractual liquidation of the leasing portfolio are expected to be sufficient
to repay. Operating cash flows of Discontinued Operations, which include cash
flows from the operations of the businesses prior to the date of disposal as
well as payments for disposition-related costs, are presented separately from
Continuing Operations in the Consolidated Statement of Cash Flows.

NOTE 13:  RESTRUCTURING

In recent years, we have restructured our corporate headquarters and certain
businesses in an effort to reduce our cost structure and remain competitive.
Restructuring activities primarily involve the separation of employees,
termination of leases, and other similar actions. Costs for restructuring
activities are limited to incremental costs that directly result from the
restructuring activities and provide no future benefit.

Generally, separated employees receive benefits under certain plans, including
layoff income benefits, retraining, and/or outplacement assistance. The amount
included for these benefits in the restructuring charge represents the
incremental cost of such benefits over those amounts previously accrued under
SFAS No. 112, "Employers' Accounting for Postemployment Benefits."

Restructuring costs totaling $2 million in 1999, $62 million in 1998 and $15
million in 1997 are included in our results of operations. Except for lease
termination and other facility closure costs of $10 million at our television
segment in 1998, these costs were essentially for the elimination of positions
and separation of employees. Expenditures for employee separation costs
generally are paid over a period of up to two years following the separation
although payments can extend longer in certain cases. Certain expenditures for
lease commitments will extend over the next several years. The remaining
liability of $15 million at December 31, 1999 is primarily for lease termination
costs and to a lesser extent employee separation costs.

The 1998 plan primarily included the separation of 441 employees and the
termination of leases at our Television and Cable segments. Implementation of
the plan began in September 1998 and was to be completed in 1999. Of the 441
employees, 283 employees have been terminated through December 31, 1999 while 80
employees will no longer be terminated. The remaining 78 employees are expected
to be terminated by year-end 2000. In the second quarter of 1999, we reversed a
total of $26 million of the $62 million restructuring reserve primarily as a
result of television programming changes and lower than expected severance
costs.

The 1997 plan primarily included the separation of 118 employees at the former
Pittsburgh headquarters related to the transfer of our overhead functions to New
York. Implementation of this plan began in January 1998 and was completed by the
end of 1999. Future expenditures for the 1997 plan consist prima-

rily of remaining lease commitments and separation costs for actions already
taken.

The following is a reconciliation of the restructuring liability:

Subsequent to December 31, 1999, we approved a proposed plan to integrate the
newly acquired operations of King World with the existing CBS syndication
business to achieve synergies and eliminate redundant functions. The plan is
expected to result in a restructuring accrual in the range of $10 million to $14
million in 2000 and reflects primarily severance-related and relocation costs of
the acquired business. Restructuring costs related to the historical operating
activities of King World will increase goodwill and those costs incurred
relating to the existing CBS syndication business will be charged to operations.
The restructuring accrual includes severance-related and relocation costs of the
acquired business for approximately 70 employees in redundant functions and are
expected to be paid by year-end 2000. Terminations of employees are expected to
be completed by year-end 2000.

NOTE 14:  LEASES AND OTHER COMMITMENTS

LEASES

We lease certain office space and equipment through various operating and
capital lease agreements. Rental expense for Continuing Operations was $131
million in 1999, $85 million in 1998 and $64 million in 1997. These amounts
include immaterial amounts for contingent rentals and sublease income.

Additionally, our outdoor advertising business has franchise rights entitling it
to display advertising on such media as buses, taxis, trains, bus shelters,
terminals, billboards, and phone kiosks. Under most of these franchise
agreements, the franchiser is entitled to receive the greater of a percentage of
the relevant advertising revenues, net of advertising agency fees, or a
specified guaranteed minimum annual payment. Franchise expense totaled $271
million in 1999, $222 million in 1998 and $192 million in 1997.

Future minimum rental and franchise payments are as follows:

OTHER COMMITMENTS

We routinely enter into commitments to purchase the rights to broadcast
programs, including feature films and sports events. These contracts permit the
broadcast of such properties for various periods. At December 31, 1999, we were
committed to make payments under such broadcasting contracts, along with
commitments for talent contracts, of $13.5 billion.

Aggregate payments related to these commitments during the next five years and
thereafter are as follows:

NOTE 15:  SHAREHOLDERS' EQUITY

Our Board of Directors authorized a $3 billion multi-year stock repurchase
program in 1998. During 1999, we purchased 11.5 million shares for $489 million,
bringing our total share repurchases under this program to 39.8 million shares
for $1.3 billion. Of the common stock held in treasury at December 31, 1999 and
1998, 14 million and 16 million shares, respectively, were held by our rabbi
trusts for the payment of benefits under executive benefit plans.

In October 1999, in conjunction with our acquisition of KTVT-TV in Dallas
Fort-Worth, we issued 10,142

                                                      CBS CORPORATION         49
<PAGE>   50

shares of CBS Series B participating preferred stock (the preferred stock) with
a par value $1.00 per share. Total consideration for the issuance of the
preferred stock was $485 million. Holders of the preferred stock are entitled to
receive, when and if declared by the Board of Directors, a cash dividend equal
to 1,000 times the aggregate per share amount of each cash dividend declared or
paid on the CBS common stock. Each share of the preferred stock is entitled to
1,000 votes per share and is convertible at the option of the holder into 1,000
shares of our common stock. Approximately 10,142,000 common shares have been
reserved for conversion. The preferred stock ranks senior to the common shares
outstanding. The liquidation preference of the preferred stock is equal to the
greater of $1.00 per share plus accrued and unpaid dividends, or an amount equal
to 1,000 times the per share amount to be distributed to common shareholders.

On May 30, 1997, we redeemed all outstanding shares of CBS Series C Conversion
Preferred Stock (Series C Preferred) and, in connection with the redemption,
issued 32 million shares of common stock. All accrued and unpaid dividends on
the redeemed shares of CBS Series C Preferred were paid on May 30, 1997.

On December 29, 1995, the Board of Directors adopted a shareholder rights plan
providing for the distribution of one right for each share of common stock
outstanding on January 9, 1996 or issued thereafter until the occurrence of
certain events. The rights become exercisable only in the event, with certain
exceptions, that an acquiring party accumulates 15% or more of our voting stock
or a party announces an offer to acquire 30% or more of the voting stock. The
rights have an exercise price of $64 per share and expire on January 9, 2006.
The Board of Directors has adopted a resolution affirming its intention to
redeem the rights in January 2001 (if still outstanding). Upon the occurrence of
certain events, holders of the rights will be entitled to purchase either CBS
preferred shares or shares in an acquiring entity at half of their market value.
We are entitled to redeem the rights at a value of $.01 per right at any time
until the tenth day following the acquisition of a 15% position in our voting
stock. The rights will expire at the time of consummation of the Viacom/CBS
merger.

OTHER COMPREHENSIVE INCOME

In 1998 we adopted SFAS No. 130, "Reporting Comprehensive Income," which
establishes standards for reporting and display of comprehensive income and its
components in the financial statements but did not change the recognition or
measurement of assets and liabilities. Comprehensive income is used to describe
all changes in equity from transactions and other events and circumstances from
nonowner sources. Comprehensive income includes net income and other
comprehensive income or loss items.

The following table presents the components of Accumulated other comprehensive
loss, net of related taxes presented in our Consolidated Balance Sheet:

NOTE 16:  SUBSIDIARY STOCK TRANSACTIONS

In December 1998, Infinity Broadcasting, our then wholly owned subsidiary,
issued 155 million shares of its Class A common stock in an initial public
offering (IPO). We own all of the 700 million outstanding shares of Infinity
Broadcasting's Class B common stock. Holders of Infinity Broadcasting Class A
common stock generally have identical rights to the

 50        CBS CORPORATION
<PAGE>   51

holders of Infinity Broadcasting Class B common stock except that the holders of
the Class A common stock are entitled to one vote per share, while holders of
the Class B common stock are entitled to five votes per share on matters
submitted to a vote of the stockholders. In addition, the shares of Class B
common stock maintain certain conversion rights and transfer restrictions. As a
result of the IPO, at December 31, 1998, we beneficially owned 82% of Infinity
Broadcasting's equity, which represented 96% of the voting power.

Proceeds from the offering, based on the offering price of $20.50 per share,
totaled $3.2 billion ($3.0 billion, net of offering expenses). A gain of $1.4
billion was recognized in shareholders' equity as a direct increase in capital
in excess of par value.

In June 1999, Infinity Broadcasting's Board of Directors authorized a $500
million stock repurchase program. By December 31, 1999 Infinity Broadcasting had
bought back approximately 17.6 million Class A common shares at a total cost of
$485 million. This stock repurchase program resulted in an increase in our
ownership interest to approximately 84%, excluding the dilutive effect of stock
options, and resulted in incremental goodwill of approximately $300 million. In
January 2000, Infinity Broadcasting's Board of Directors authorized an
additional $500 million stock repurchase plan.

The increase in our ownership interest as a result of stock repurchases under
the above described plan was more than offset by Infinity Broadcasting's $8.7
billion, December 7, 1999, acquisition of Outdoor Systems through the issuance
of approximately 233 million shares of Infinity Broadcasting Class A common
stock. This issuance reduced our ownership interest in Infinity Broadcasting
from approximately 84% to just over 65% and reduced our voting interest to
approximately 90%, both excluding the dilutive effect of stock options. The
impact of this issuance of subsidiary stock resulted in the recognition of
approximately a $2.7 billion gain through shareholders' equity as a direct
increase to capital in excess of par value. The reduction in our ownership
interest also results in an increase in minority interest participation at the
time of the transaction and in Infinity Broadcasting's future results of
operations from the date of the transaction.

Additionally, during 1999, stock transactions of our equity method investees
resulted in our recording a net gain of approximately $135 million through
shareholders' equity as a direct increase to capital in excess of par value. The
offset resulted in a net increase in our related investment balances for the
respective investees.

Under an intercompany agreement, we provide to Infinity Broadcasting a number of
services, including executive, human resources, legal, finance, information
management, internal audit, tax, and treasury services. The costs of these
services are allocated according to established methodologies determined on an
annual basis. In addition, a tax sharing agreement generally provides that, for
any taxable period in which Infinity Broadcasting is included in our
consolidated tax return, the amount of income taxes to be paid by them were
determined as if they had filed separate income tax returns. At the time of the
Outdoor Systems acquisition, because our ownership interest in Infinity
Broadcasting fell below 80% they no longer qualified for inclusion in our
federal income tax filing and some state tax combine filings, and therefore in
those instances they will be filing a separate tax return.

NOTE 17:  STOCK-BASED COMPENSATION PLANS

At December 31, 1999, we had stock-based compensation plans at CBS and Infinity
Broadcasting that provide for the granting of stock options, restricted stock,
and other performance awards to employees or directors. We account for our
stock-based compensation plans under APB 25. For stock options granted, the
option price is not less than the market value of shares on the grant date;
therefore, no compensation cost has been recognized for stock options granted.
Had compensation cost for these plans been determined under the provisions of
SFAS 123, our net income and earnings per share would have been reduced to the

These pro forma effects may not be representative of future amounts since the
estimated fair value of stock options on the date of grant is amortized to
expense over the vesting period, and additional options may be granted in future
years.

CBS STOCK OPTION PLANS

At December 31, 1999, shares authorized for awards under the CBS plans totaled
66.9 million of which 10.3 million shares remained available for future awards.
Generally, stock option awards vest over a three-year period from the date of
grant and expire 10 years after the date of grant.

In connection with the acquisitions of King World, TNN and CMT, and Infinity
Media Corporation, we assumed options outstanding under the King World, Gaylord
and Infinity Media Corporation plans as of the date of the acquisition. The
then-outstanding options were converted to options to acquire CBS's common stock
and are included in the following table as awards assumed. Exercise prices for
awards assumed in the 1999 King World acquisition range from $12.81 to $44.30.
Exercise prices for awards assumed in the 1997 TNN and CMT acquisition, range
from $9.45 to $25.41. Exercise prices for awards assumed in the 1996 Infinity
Media Corporation acquisition, range from $0.0002 to $19.66. Generally, these
options assumed have a ten-year term and become exercisable over a vesting
period of five years.

In addition to the stock options shown in the following table, we granted 8,903
shares, 9,493 shares and 9,449 shares of restricted stock to employees and
directors in 1999, 1998 and 1997, respectively. These shares had a
weighted-average fair value at date of grant of $34.64, $29.96 and $18.52,
respectively, with a weighted-average vesting period of one year.

Each CBS option outstanding at the time of the merger will convert into 1.085
options to purchase shares of Viacom non-voting Class B common stock at an
exercise price adjusted for the 1.085 conversion factor. The majority of these
options contain a provision that accelerates their vesting upon a change in
control. The consummation of the merger with Viacom would be considered to be a
change in control under a majority of these option agreements. Therefore,
approximately 11 million of unvested options outstanding at the date we entered
into the merger agreement will become fully vested upon the closing of the
transaction.

Additionally, approximately 36 million of the options outstanding at the date we
entered into the merger agreement contain a limited stock appreciation right
feature that becomes exercisable for a thirty-day period upon a change in
control. This feature entitles the holder to receive the highest reported
closing sales price of a share of CBS common stock on the New York Stock
Exchange during a period preceding the date of exercise.

INFINITY STOCK OPTION PLANS

At December 31, 1999, Infinity Broadcasting had several stock-based compensation
plans that provide for the granting of stock-based awards, including non-
statutory stock options, to non-employee directors of Infinity Broadcasting, and
to officers or employees of Infinity Broadcasting, its parent or their
subsidiaries. At December 31, 1999, approximately 18 million shares (excluding
Outdoor Systems options assumed) of Infinity Broadcasting's Class A common stock
were authorized for awards under the plans of which 12 million shares remained
available for future awards. Generally, stock option awards vest three-years
from the date of grant and expire ten years from the date of grant.

In conjunction with the acquisition of Outdoor Systems on December 7, 1999,
Infinity Broadcasting assumed 28 million options to acquire shares of Infinity
Broadcasting's Class A common stock with a weighted-average exercise price of
$2.89 per share.

NOTE 18:  SEGMENT INFORMATION

In 1998, we adopted SFAS No. 131, "Disclosure about Segments of a Business
Enterprise and Related Information." The segment information reflects a new
organizational structure which presents our Internet operations as a separate
segment called the Internet Group, formerly referred to as New Media. These
results were previously reported within the Television segment. This change was
as a result of our growth in Internet based companies during 1999 and the
identification of a separate management team to run these operations. The prior
segment information presented in this note has been restated to reflect the
Internet Group as a separate segment.

We are aligned into four business segments: Infinity, Television, Cable and the
Internet Group. These business segments are consistent with our management of
these businesses, our financial reporting structure and operating focus.

Our segments operate predominately in the United States. The accounting policies
as described in the summary of significant accounting policies note are applied
consistently across the segments. Intersegment sales and transfers are not
material to our Infinity, Television and Cable segment results and are
eliminated in Corporate and Other. Our Internet Group segment includes $19
million of advertising expense for our consolidated Internet investments for
advertising and promotion time provided by our Infinity, Television and Cable
segments.

We evaluate operating performance based on earnings before interest, taxes,
minority interest, equity losses, depreciation and amortization (EBITDA). We
believe that EBITDA is an appropriate measure of evaluating the operating
performance of our segments. EBITDA eliminates the effect of depreciation and
amortization of tangible and intangible assets caused by the

 54        CBS CORPORATION
<PAGE>   55

magnitude and timing of acquisitions. However, EBITDA should be considered in
addition to, not as a substitute for operating earnings, net earnings, cash
flows, and other measures of financial performance reported in accordance with
generally accepted accounting principles. As EBITDA is not a measure of
performance calculated in accordance with generally accepted accounting
principles, this measure may not be comparable to similarly titled measures
employed by other companies.

INFINITY

Management characterizes its Infinity segment as out-of-home media because the
majority of radio listening and virtually all viewing of outdoor advertising
takes place in automobiles, transit systems, on the street and other locations
outside the consumer's home, including listening to radio at work. The Infinity
segment owns and operates radio stations and participates in the outdoor
advertising business. Radio station revenues were 75% in 1999, 77% in 1998 and
75% in 1997 of total Infinity revenues. The percentage of outdoor revenues is
expected to increase in 2000 due to the full-year impact of the December 1999
acquisition of Outdoor Systems. Infinity Broadcasting owns and operates 162
radio stations located in 34 markets. Sixty-two of these radio stations are in
the nation's ten largest radio markets. We believe that the presence of Infinity
Broadcasting's radio stations in large markets makes it attractive to
advertisers and that the overall diversity of its stations reduces its
dependence on any single station, local economy, or advertiser. Infinity
Broadcasting also has a minority equity investment in Westwood One, Inc.
(Westwood One), which it manages. Westwood One produces and distributes
syndicated and network radio programming and also manages the CBS Radio Network.

Infinity Broadcasting operates the largest outdoor advertising business in North
America through its wholly owned subsidiaries. Our outdoor advertising business
sells advertising space throughout the United States, United Kingdom, Republic
of Ireland, Canada, Mexico, and the Netherlands on various media, including
buses, trains, malls, train platforms and terminals throughout commuter rail
systems, and on painted billboards, eight and thirty-sheet posters, and phone
kiosks.

TELEVISION

The Television segment consists of three integrated operations: the CBS
television network; our owned and operated television stations; and our
television syndication operations. In November 1999, we acquired King World, a
leading syndicator of television programming. See note 2 to the financial
statements.

The CBS television network produces or acquires, and distributes a comprehensive
schedule of news, public affairs, entertainment and sports programming, to our

                                                      CBS CORPORATION         55
<PAGE>   56

owned and operated television stations and more than 200 affiliates. Our owned
and operated television stations and domestic affiliates serve, in the
aggregate, all 50 states and the District of Columbia. The television network is
responsible for sales of advertising time for the television network broadcasts
of news, public affairs, sports and entertainment programming. Our programming
also involves the production, distribution and marketing of first-run and
off-network syndicated programming to television stations, cable, home video,
in-flight, and emerging media worldwide. Subsequent to December 31, 1999, we
approved a proposed plan to integrate the newly acquired operations of King
World with the existing CBS syndication business to achieve synergies and
eliminate redundant functions. See notes 2 and 13 to the financial statements.

The success of our television segment is driven primarily by programming. Our
network depends on our owned and operated television stations, our television
syndication operations and the affiliates for distribution of the programming.
In addition, the network provides the majority of programming aired at our owned
and operated television stations.

CABLE

The Cable segment primarily consists of our cable networks, including TNN, CMT
and two regional sports networks. These networks are distributed by cable
television and other multi-channel technologies.

TNN is an advertiser-supported cable network featuring country lifestyle and
entertainment programming. The network serves approximately 76 million U.S.
homes. TNN offers a broad array of programming from original series to movies to
country music concerts as well as motorsports, including the NASCAR Winston Cup
Races, outdoor sports such as hunting and fishing, professional bull riding and
sports entertainment such as wrestling. In April 2000, TNN is expected to be the
primary network for the Arena Football League. Our rights to broadcast the
NASCAR Winston Cup races were not renewed and expire during the year 2000.

CMT is an advertiser-supported, 24-hour cable network with a country music video
format. It reaches approximately 39 million U.S. homes.

In addition, we own and operate the Midwest Sports Channel, a regional sports
network in Minneapolis, and we are a majority owner of Home Team Sports, a
regional sports network serving the mid-Atlantic states.

Also part of the cable operations, Group W Network Services (GWNS) is a global
provider of satellite services to broadcast, cable, and corporate networks.
Based in Stamford, Connecticut, GWNS provides transmission and other technical
services to U.S. broadcast networks and to many major cable networks.

INTERNET GROUP

The Internet Group segment consists of our consolidated and nonconsolidated
Internet businesses including CBS.com, Inc. the operator of two Internet sites-
CBS.com and CBSNews.com. CBS.com, which launched in February 1998, offers a
broad range of informational, entertainment, news, and promotional content. In
January 2000, CBS.com, Inc. launched CBSNews.com, a news and news related
information web site. A majority of the television network affiliates currently
participate in these web sites. During the second half of 1999, we closed on a
number of strategic investments focused on growing our Internet based
operations. We received an equity interest in these Internet companies,
primarily in exchange for future advertising and promotion time on our
television, radio, outdoor and cable media properties. The segment data tables
above, except total assets, exclude the effect of changes in market value for
our publicly traded cost method investments and the results of operations for
our equity method of accounting Internet investments. Our proportionate share of
losses and related amortization expense in our equity method investments are
reported separately as Equity losses of unconsolidated affiliated companies, net
of income taxes on the Consolidated Statement of Income. The appreciation or
depreciation in the stock prices on our publicly traded cost method Internet
investments are recorded as a component of Accumulated other comprehensive loss
in shareholders' equity. In exchange for providing advertising and promotion
time on its media properties, Infinity Broadcasting will be provided an economic
interest in certain of these Internet investments. See note 3 to the financial
statements.

OTHER

The category "Corporate and Other" includes certain assets and results of
operations that are either not identifiable to a specific reportable segment or
relate to the maintenance of corporate functions. These assets primarily include
cash and cash equivalents, deferred income taxes, property and equipment and
other assets associated with corporate headquarters as well as certain
receivables. Included in the results of

 56        CBS CORPORATION
<PAGE>   57

operations are intersegment eliminations, non-allocated income and costs related
to interest, taxes and employee benefits as well as certain headquarters related
income and expenses.

Residual costs of discontinued businesses primarily include pension and
postretirement benefit costs for benefit plans retained by us for previously
divested industrial businesses.

Long-lived assets include property and equipment, programming, noncurrent
receivables, and investments in joint ventures or other affiliates, and exclude
such assets as goodwill, FCC licenses, other intangible assets, financial
instruments, deferred acquisition costs and deferred tax assets. Increases in
long-lived assets during 1999 and 1998 are due primarily to acquisitions.

Expenditures for long-lived assets are primarily related to spending on
programming of $193 million, $108 million, and $161 million as well as capital
spending of $171 million, $139 million, and $121 million during 1999, 1998, and
1997, respectively.

NOTE 19:  CONTINGENT LIABILITIES,

Certain environmental, litigation and other liabilities associated with the
industrial businesses were not assumed by other parties in the divestiture
transactions and, therefore, were retained by us. These liabilities include
certain environmental, general litigation, and other matters not involving
active businesses. Accrued liabilities associated with these matters, which have
been separately presented in Continuing Operations as Retained liabilities of
discontinued businesses, totaled $1.2 billion at December 31, 1999, including
$581 million for accrued legal matters as well as amounts related to previously
discontinued businesses of CBS Inc. Of the $1.2 billion, $996 million is
classified as noncurrent. A separate asset of $202 million was recorded for
estimated amounts recoverable from third parties, of which $175 million is
classified in Other noncurrent assets in the Consolidated Balance Sheet.

LEGAL MATTERS

SECURITIES CLASS ACTIONS--FINANCIAL SERVICES

We have been defending derivative and class action lawsuits alleging federal
securities law and common law violations arising out of purported misstatements
or omissions contained in public filings and in a Prospectus and Registration
Statement for a public offering of CBS's common stock in 1991. The parties to
the class actions and derivative action reached an agreement to settle the
matters for a total cost of $67 million, funded in large part by our liability
insurers. On October 19, 1999, the district court approved the settlements and
our share was paid in 1999. The parties await the entry of a final order by the
district court.

ASBESTOS

We are a defendant in numerous lawsuits claiming various asbestos-related
personal injuries, which allegedly occurred from use or inclusion of asbestos in
certain products supplied by the industrial businesses, generally in the
pre-1970 time period. Typically, these lawsuits are brought against multiple
defendants. We were neither a manufacturer nor a producer of asbestos and we are
oftentimes dismissed from these lawsuits on the basis that we have no
relationship to the products in question or the claimant did not have exposure
to our product. At December 31, 1999, we had approximately 121,000 unresolved
claims pending.

In court actions that have been resolved, we have prevailed in many of the
asbestos claims and have resolved others through settlement. Furthermore, we
have brought suit against certain of our insurance carriers with respect to
these asbestos claims. Under the terms of a settlement agreement resulting from
this suit, carriers that have agreed to the settlement are now reimbursing us
for a substantial portion of our current costs and settlements associated with
asbestos claims. We recorded a liability reflected in Retained liabilities of
discontinued businesses for asbestos-related matters that is deemed probable and
can be reasonably estimated. We have also separately recorded an asset reflected
in Other noncurrent assets in the Consolidated Balance Sheet equal to the amount
of such estimated liability that will be recovered pursuant to agreements with
insurance carriers.

Factors considered in evaluating this litigation include: claimed product
involvement, alleged exposure to product, alleged disease, validity of medical
claims, number of resolved claims, available insurance proceeds and status of
litigation in multiple jurisdictions. We have not been able to reasonably
estimate costs for unasserted asbestos claims. However, we review asbestos
claims on an ongoing basis and adjust our liability as appropriate.

GENERAL

Litigation is inherently uncertain and always difficult to predict. Substantial
damages are sought in certain

                                                      CBS CORPORATION         57
<PAGE>   58

groupings of asbestos claims, and, although we believe a significant adverse
judgment is unlikely, any such judgment could have a material adverse effect on
our results of operations for a quarter or a year. However, based on our
understanding and evaluation of the relevant facts and circumstances, we believe
that we have adequately provided for costs arising from resolution of these
matters and that the litigation should not have a material adverse effect on our
financial condition.

ENVIRONMENTAL MATTERS

Compliance with federal, state, and local laws and regulations relating to the
discharge of pollutants into the environment, the disposal of hazardous wastes,
and other related activities affecting the environment have had and will
continue to have an impact on us. It is difficult to estimate the timing and
ultimate costs to be incurred in the future due to uncertainties about the
status of laws, regulations, and technology; the adequacy of information
available for individual sites; the extended time periods over which site
remediation occurs; and the identification of new sites. We have, however,
recognized an estimated liability, measured in current dollars, for those sites
where it is probable that a loss has been incurred and the amount of the loss
can be reasonably estimated. We recognize changes in estimates as new
remediation requirements are defined or as more information becomes available.

With regard to remedial actions under federal and state Superfund laws, we have
been named a potentially responsible party (PRP) at numerous sites located
throughout the country. At many of these sites, we are either not a responsible
party or its site involvement is very limited or de minimis. However, we may
have varying degrees of cleanup responsibilities at approximately 74 sites. We
believe that any liability incurred for cleanup at these sites will be satisfied
over a number of years, and in many cases, the costs will be shared with other
responsible parties. These sites include certain sites for which we, as part of
an agreement for sale, have retained obligations for remediation of
environmental contamination and for other Comprehensive Environmental Response
Compensation and Liability Act (CERCLA) issues.

Based on the costs associated with the most probable alternative remediation
strategy for the previously mentioned sites, we have an accrued liability of
$514 million at December 31, 1999 which is reflected in Retained liabilities of
discontinued businesses in the Consolidated Balance Sheet. Depending on the
remediation alternatives ultimately selected, the costs related to these sites
could differ from the amounts currently accrued. The accrued liability includes
$397 million for site investigation and remediation, and $117 million for
post-closure and monitoring activities. Management anticipates that the majority
of expenditures for site investigation and remediation will occur during the
next five to ten years. Expenditures for post-closure and monitoring activities
will be made during periods of up to 30 years.

OTHER

We are involved with several administrative actions alleging violations of
federal, state, or local environmental regulations. For these matters, we have
estimated our remaining reasonably possible costs and determined them to be
immaterial.

We believe, based on our best estimate, that we have adequately provided for the
present environmental obligations and that complying with existing government
regulations will not materially impact our financial position, liquidity or
results of operations.

NOTE 20:  SUBSEQUENT EVENT (AS OF MARCH 21, 2000)

On March 3, 2000, Infinity Broadcasting entered into an asset purchase agreement
to acquire 18 radio stations, located in the top 50 markets, from Clear Channel
Communications, Inc. for approximately $1.4 billion. This transaction is
expected to close by year-end 2000 and is subject to regulatory reviews and
approvals.

On March 21, 2000, Infinity Broadcasting announced that it had entered into an
agreement to purchase Giraudy, one of France's largest outdoor advertising
companies, for approximately $425 million. This transaction is expected to close
mid-year 2000.

Infinity Broadcasting plans to finance these acquisitions with excess cash from
operations and by executing a credit facility which will increase their
borrowing availability by $2.0 billion.

We have made numerous acquisitions in the last three years, see note 2 to the
financial statements. On December 31, 1996, we acquired Infinity Media
Corporation which gave rise to the year-over-year increases in 1997. In November
1995, we acquired CBS Inc. which gave rise to the significant year-over-year
increases in 1996. See note 12 to the financial statements for discussions on
discontinued businesses.

(a) We evaluate our operating performance based on several factors, of which the
    primary financial measure is earnings before interest, taxes, minority
    interest, equity losses, depreciation, and amortization (EBITDA). EBITDA
    eliminates the effect of depreciation and amortization of tangible and
    intangible assets, most of which were from acquisitions accounted for under
    the purchase method of accounting. However, EBITDA should be considered in
    addition to, not as a substitute for, operating earnings, net earnings, cash
    flows, and other measures of financial performance reported in accordance
    with generally accepted accounting principles. As EBITDA is not a measure of
    performance calculated in accordance with generally accepted accounting
    principles, this measure may not be comparable to similarly titled measures
    employed by other companies. EBITDA differs from cash flows from operating
    activities primarily because it does not consider changes in assets and
    liabilities from period to period, and it does not include cash flows for
    interest and taxes.

(b) Represents the closing price for one share of CBS common stock on the NYSE.

INDEPENDENT AUDITORS' REPORT ON FINANCIAL STATEMENT SCHEDULE

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF CBS CORPORATION

Under date of January 25, 2000, except as to note 20, which is as of March 21,
2000, we reported on the consolidated balance sheet of CBS Corporation and
subsidiaries as of December 31, 1999 and 1998, and the related consolidated
statements of income and comprehensive income, cash flows, and shareholders'
equity, for each of the years in the three year period ended December 31, 1999,

1999 Annual Report on Form 10-K. The consolidated financial statement schedule
is the responsibility of management. Our responsibility is to express an opinion

In our opinion, the December 31, 1999, 1998, and 1997 consolidated financial
statement schedule, when considered in relation to the basic consolidated
financial statements taken as a whole, presents fairly, in all material
respects, the information set forth therein.

         SECTION 1.2. Terms Generally. (a) The definitions in Section 1.1 shall
apply equally to both the singular and plural forms of the terms defined.
Whenever the context may require, any pronoun shall include the corresponding
masculine, feminine and neuter forms. The words "include", "includes" and
"including" shall, except where the context otherwise requires, be deemed to be
followed by the phrase "without limitation". All references herein to Articles,
Sections, Exhibits and Schedules shall be deemed references to Articles and
Sections of, and Exhibits and Schedules to, this Agreement unless the context
shall otherwise require.

         (b) Except as otherwise expressly provided herein, all terms of an
accounting nature shall be construed in accordance with GAAP as in effect from
time to time; provided, however, that, for purposes of determining compliance
with the covenants set forth in Sections 5.7, 5.8 and 5.9 (such
<PAGE>   23
                                                                              19


Sections being referred to as the "Financial Covenants"), except as otherwise
set forth in the Financial Covenants and the definitions related thereto, such
terms shall be construed in accordance with GAAP as in effect on March 31, 1996,
applied on a basis consistent with the application used in preparing the 1996
First Quarter Financial Statements.

         (c) For the purposes of calculating Consolidated EBITDA and
Consolidated Interest Expense for any period (a "Test Period"), (i) if at any
time from the period (a "Pro Forma Period") commencing on the second day of such
Test Period and ending on the date which is ten days prior to the date of
delivery of the Compliance Certificate or Interim Certificate, as the case may
be, in respect of such Test Period (or, in the case of any pro forma calculation
made pursuant hereto in respect of a particular transaction, ending on the date
such transaction is consummated after giving effect thereto), CBS or any
Subsidiary shall have made any Material Disposition, the Consolidated EBITDA for
such Test Period shall be reduced by an amount equal to the Consolidated EBITDA
(if positive) attributable to the Property which is the subject of such Material
Disposition for such Test Period or increased by an amount equal to the
Consolidated EBITDA (if negative) attributable thereto for such Test Period, and
Consolidated Interest Expense for such Test Period shall be reduced by an amount
equal to the Consolidated Interest Expense for such Test Period attributable to
any Indebtedness of CBS or any Subsidiary repaid, repurchased, defeased or
otherwise discharged with respect to CBS and its Subsidiaries in connection with
such Material Disposition (or, if the Capital Stock of any Subsidiary is sold,
the Consolidated Interest Expense for such Test Period directly attributable to
the Indebtedness of such Subsidiary to the extent CBS and its continuing
Subsidiaries are no longer liable for such Indebtedness after such Disposition);
(ii) if during such Pro Forma Period CBS or any Subsidiary shall have made a
Material Acquisition, Consolidated EBITDA and Consolidated Interest Expense for
such Test Period shall be calculated after giving pro forma effect thereto
(including the incurrence or assumption of any Indebtedness in connection
therewith) as if such Material Acquisition (and the incurrence or assumption of
any such Indebtedness) occurred on the first day of such Test Period; (iii) if
during such Pro Forma Period any Person that subsequently became a Subsidiary or
was merged with or into CBS or any Subsidiary since the beginning of such Pro
Forma Period shall have entered into any disposition or acquisition transaction
that would have required an adjustment pursuant to clause (i) or (ii) above if
made by CBS or a Subsidiary during such Pro Forma Period, Consolidated EBITDA
and Consolidated Interest Expense for such Test Period shall be calculated after
giving pro forma effect thereto as if such transaction occurred on the first day
of such Test Period; and (iv) the financial results and effects of the
operations of the Eye on People and TeleNoticias businesses shall be entirely
excluded from Consolidated EBITDA. For the purposes of this paragraph, whenever
pro forma effect is to be given to a Material Disposition or Material
Acquisition, the amount of income or earnings relating thereto and the amount of
Consolidated Interest Expense associated with any Indebtedness discharged or
incurred in connection therewith, the pro forma calculations shall be determined
in good faith by a Financial Officer of CBS. If any Indebtedness bears a
floating rate of interest and the incurrence or assumption thereof is being
given pro forma effect, the interest expense on such Indebtedness shall be
calculated as if the rate in effect on the last day of the relevant Pro Forma
Period had been the applicable rate for the entire relevant Test Period (taking
into account any interest rate protection agreement applicable to such
Indebtedness if such interest rate protection agreement has a remaining term in
excess of 12 months).

         (d) For the purposes of the Financial Covenants, (i) the Discontinued
Operations shall be disregarded and (ii) the businesses classified as
Discontinued Operations shall be limited to those businesses treated as such in
the financial statements of CBS referred to in the definition of "Discontinued
Operations" and the accounting treatment of Discontinued Operations shall be
consistent with the accounting treatment thereof in such financial statements.

                                   ARTICLE II.

                                   THE CREDITS

         SECTION 2.1. Commitments. Subject to the terms and conditions hereof
and relying upon the representations and warranties herein set forth, each
Lender agrees, severally and not jointly, to make Revolving Credit Loans to CBS
or any Subsidiary Borrower, at any time and from time to time on and after the
Closing Date and until the earlier of (a) the Business Day immediately preceding
the Revolving Credit Maturity Date and (b) the termination of the Commitment of
such Lender, in an aggregate principal amount at any time outstanding not to
exceed such Lender's Commitment. Each Borrower may borrow, prepay and reborrow
Revolving Credit Loans on and after the Closing Date and prior to the Revolving
Credit Maturity Date, subject to the terms, conditions and limitations set forth
herein. On the Closing Date, all loans and obligations of, and any Letters of
Credit issued on behalf of, CBS and any Subsidiary Borrowers thereunder (other
than Infinity and its Subsidiaries) under or in connection with the Existing
Credit Agreement shall be deemed to be outstanding hereunder and not under the
Existing Credit Agreement.

         SECTION 2.2. Revolving Credit Loans; Competitive Loans. (a) Each
Revolving Credit Loan shall be made to the relevant Borrower by the Lenders
ratably in accordance with their respective Commitments. Each Competitive Loan
shall be made to the relevant Borrower by the Lender whose Competitive Bid
therefor is accepted, and in the amount so accepted, in accordance with the
procedures set forth in Section 2.3. The Revolving Credit Loans or Competitive
Loans shall be made in minimum amounts equal to (i) in the case of Competitive
Loans, $5,000,000 or an integral multiple of $1,000,000 in excess thereof, (ii)
in the case of Eurodollar Revolving Credit Loans, $50,000,000 or an integral
multiple of $5,000,000 in excess thereof, and (iii) in the case of ABR Revolving
Credit Loans, $25,000,000 or an integral multiple of $5,000,000 in excess
thereof (or an aggregate principal amount equal to the remaining balance of the
available Total Commitment).

         (b) Each Lender shall make each Loan (other than a Swingline Loan, as
to which this Section 2.2 shall not apply) to be made by it on the proposed date
thereof by wire transfer of immediately available funds to the Administrative
Agent in New York, New York, not later than 12:00 noon, New York City time (or,
in connection with an ABR Loan to be made on the same day on which a notice is
submitted, 12:30 p.m., New York City time) and the Administrative Agent shall by
3:00 p.m., New York City time, credit the amounts so received to the general
deposit account of the relevant Borrower with the Administrative Agent.

         SECTION 2.3. Competitive Bid Procedure. (a) In order to request
Competitive Bids, the relevant Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Competitive Bid Request in the form of
Exhibit B-1, to be received by the Administrative Agent (i) in the case of a
Eurodollar Competitive Loan, not later than 10:00 a.m., New York City time, four
Business Days before a proposed Competitive Loan and (ii) in the case of an
Absolute Rate Loan, not later than 10:00 a.m., New York City time, one Business
Day before a proposed Competitive Loan. A Competitive Bid Request that does not
conform substantially to the format of Exhibit B-1 may be rejected in the
Administrative Agent's discretion (exercised in good faith), and the
Administrative Agent shall promptly notify the relevant Borrower of such
rejection by telephone, confirmed by telecopier. Such request shall in each case
refer to this Agreement and specify (x) whether the Competitive Loan then being
requested is to be a Eurodollar Competitive Loan or an Absolute Rate Loan, (y)
the date of such Loan (which shall be a Business Day) and the aggregate
principal amount thereof which shall be in a minimum principal amount of
$5,000,000 and in an integral multiple of $1,000,000, and (z) the Interest
Period with respect
<PAGE>   25
                                                                              21


thereto (which may not end after the Revolving Credit Maturity Date). Promptly
after its receipt of a Competitive Bid Request that is not rejected as aforesaid
(and in any event by 5:00 p.m., New York City time, on the date of such receipt
if such receipt occurs by the time specified in the first sentence of this
paragraph), the Administrative Agent shall invite by telecopier (in the form set
forth in Exhibit B-2) the Lenders to bid, on the terms and conditions of this
Agreement, to make Competitive Loans pursuant to such Competitive Bid Request.

         (b) Each Lender may, in its sole discretion, make one or more
Competitive Bids to the relevant Borrower responsive to a Competitive Bid
Request. Each Competitive Bid must be received by the Administrative Agent by
telecopier, in the form of Exhibit B-3, (i) in the case of a Eurodollar
Competitive Loan, not later than 9:30 a.m., New York City time, three Business
Days before a proposed Competitive Loan and (ii) in the case of an Absolute Rate
Loan, not later than 9:30 a.m., New York City time, on the day of a proposed
Competitive Loan. Multiple Competitive Bids will be accepted by the
Administrative Agent. Competitive Bids that do not conform substantially to the
format of Exhibit B-3 may be rejected by the Administrative Agent after
conferring with, and upon the instruction of, the relevant Borrower, and the
Administrative Agent shall notify the Lender making such nonconforming
Competitive Bid of such rejection as soon as practicable. Each Competitive Bid
shall refer to this Agreement and specify (x) the principal amount (which shall
be in a minimum principal amount of $5,000,000 and in an integral multiple of
$1,000,000 and which may equal the entire principal amount of the Competitive
Loan requested by the relevant Borrower) of the Competitive Loan or Loans that
the applicable Lender is willing to make to the relevant Borrower, (y) the
Competitive Bid Rate or Rates at which such Lender is prepared to make the
Competitive Loan or Loans and (z) the Interest Period and the last day thereof.
A Competitive Bid submitted pursuant to this paragraph (b) shall be irrevocable
(subject to the satisfaction of the conditions to borrowing set forth in Article
IV).

         (c) The Administrative Agent shall promptly (and in any event by 10:15
a.m., New York City time, on the date on which such Competitive Bids shall have
been made) notify the relevant Borrower by telecopier of all the Competitive
Bids made, the Competitive Bid Rate and the principal amount of each Competitive
Loan in respect of which a Competitive Bid was made and the identity of the
Lender that made each Competitive Bid. The Administrative Agent shall send a
copy of all Competitive Bids to the relevant Borrower for its records as soon as
practicable after completion of the bidding process set forth in this Section
2.3.

         (d) The relevant Borrower may in its sole and absolute discretion,
subject only to the provisions of this paragraph (d), accept or reject any
Competitive Bid referred to in paragraph (c) above. The relevant Borrower shall
notify the Administrative Agent by telephone, confirmed by telecopier in such
form as may be agreed upon by such Borrower and the Administrative Agent,
whether and to what extent it has decided to accept or reject any of or all the
Competitive Bids referred to in paragraph (c) above, (x) in the case of a
Eurodollar Competitive Loan, not later than 11:00 a.m., New York City time,
three Business Days before a proposed Competitive Loan, and (y) in the case of
an Absolute Rate Loan, not later than 11:00 a.m., New York City time, on the day
of a proposed Competitive Loan; provided, however, that (i) the failure by such
Borrower to give such notice shall be deemed to be a rejection of all the
Competitive Bids referred to in paragraph (c) above, (ii) such Borrower shall
not accept a Competitive Bid made at a particular Competitive Bid Rate if it has
decided to reject a Competitive Bid made at a lower Competitive Bid Rate, (iii)
the aggregate amount of the Competitive Bids accepted by such Borrower shall not
exceed the principal amount specified in the Competitive Bid Request (but may be
less than that requested), (iv) if such Borrower shall accept a Competitive Bid
or Competitive Bids made at a particular Competitive Bid Rate but the amount of
such Competitive Bid or Competitive Bids shall cause the total amount of
Competitive Bids to be accepted by it to exceed the amount specified in
<PAGE>   26
                                                                              22


the Competitive Bid Request, then such Borrower shall accept a portion of such
Competitive Bid or Competitive Bids in an amount equal to the amount specified
in the Competitive Bid Request less the amount of all other Competitive Bids
accepted with respect to such Competitive Bid Request, which acceptance, in the
case of multiple Competitive Bids at such Competitive Bid Rate, shall be made
pro rata in accordance with the amount of each such Competitive Bid at such
Competitive Bid Rate, and (v) except pursuant to clause (iv) above no
Competitive Bid shall be accepted for a Competitive Loan unless such Competitive
Loan is in a minimum principal amount of $5,000,000 and an integral amount
multiple of $1,000,000; provided, further, however, that if a Competitive Loan
must be in an amount less than $5,000,000 because of the provisions of clause
(iv) above, such Competitive Loan may be for a minimum of $1,000,000 or any
integral multiple thereof, and in calculating the pro rata allocation of
acceptances of portions of multiple Competitive Bids at a particular Competitive
Bid Rate pursuant to clause (iv) the amounts shall be rounded to integral
multiples of $1,000,000 in a manner which shall be in the discretion of such
Borrower. A notice given by any Borrower pursuant to this paragraph (d) shall be
irrevocable.

         (e) The Administrative Agent shall promptly notify each bidding Lender
whether or not its Competitive Bid has been accepted (and if so, in what amount
and at what Competitive Bid Rate) by telecopy sent by the Administrative Agent,
and each successful bidder will thereupon become bound, subject to the other
applicable conditions hereof, to make the Competitive Loan in respect of which
its Competitive Bid has been accepted.

         (f) A Competitive Bid Request shall not be made within five Business
Days after the date of any previous Competitive Bid Request, unless the
Administrative Agent shall agree otherwise.

         (g) If the Lender which is the Administrative Agent shall elect to
submit a Competitive Bid in its capacity as a Lender, it shall submit such
Competitive Bid directly to the relevant Borrower one quarter of an hour earlier
than the latest time at which the other Lenders are required to submit their
Competitive Bids to the Administrative Agent pursuant to paragraph (b) above.

         (h) All notices required by this Section 2.3 shall be given in
accordance with Section 9.1.

         (i) No Borrower shall have the right to prepay any Competitive Loan
without the consent of the affected Lender or Lenders.

         SECTION 2.4. Revolving Credit Borrowing Procedure. In order to request
a Revolving Credit Loan, the relevant Borrower shall hand deliver or telecopy to
the Administrative Agent a Revolving Credit Borrowing Request in the form of
Exhibit B-4 (a) in the case of a Eurodollar Revolving Credit Loan, not later
than 11:00 a.m., New York City time, three Business Days before a proposed
borrowing and (b) in the case of an ABR Revolving Credit Loan, not later than
11:00 a.m., New York City time, on the day of a proposed borrowing. Such notice
shall be irrevocable and shall in each case specify (i) whether the Revolving
Credit Loan then being requested is to be a Eurodollar Revolving Credit Loan or
an ABR Revolving Credit Loan, (ii) the date of such Revolving Credit Loan (which
shall be a Business Day) and the amount thereof; and (iii) in the case of a
Eurodollar Revolving Credit Loan, the Interest Period with respect thereto. The
Administrative Agent shall promptly advise the Lenders of any notice given
pursuant to this Section 2.4 and of each Lender's portion of the requested Loan.

         SECTION 2.5. Repayment of Loans. Each Borrower shall repay all
outstanding Revolving Credit Loans and ABR Swingline Loans made to it, in each
case on the Revolving Credit
<PAGE>   27
                                                                              23


Maturity Date (or such earlier date on which the Commitments shall terminate in
accordance herewith). Each Borrower shall repay Quoted Swingline Loans and
Competitive Loans made to it, in each case on the Maturity Date applicable
thereto. Each Loan shall bear interest from and including the date thereof on
the outstanding principal balance thereof as set forth in Section 2.10.

         SECTION 2.6. Swingline Loans. (a) Subject to the terms and conditions
hereof and relying upon the representations and warranties herein set forth,
each Swingline Lender agrees, severally and not jointly, at any time and from
time to time on and after the Closing Date and until the earlier of the Business
Day immediately preceding the Revolving Credit Maturity Date and the termination
of the Swingline Commitment of such Swingline Lender, (i) to make available to
any Swingline Borrower Swingline Loans ("Quoted Swingline Loans") on the basis
of quoted interest rates (each, a "Quoted Swingline Rate") furnished by such
Swingline Lender from time to time in its discretion to such Swingline Borrower
(through the Administrative Agent) and accepted by such Swingline Borrower in
its discretion and (ii) to make Swingline Loans ("ABR Swingline Loans") to any
Swingline Borrower bearing interest at a rate equal to the Alternate Base Rate
in an aggregate principal amount (in the case of this clause (ii)) not to exceed
such Swingline Lender's Swingline Commitment. The aggregate outstanding
principal amount of the Quoted Swingline Loans of any Swingline Lender, when
added to the aggregate outstanding principal amount of the ABR Swingline Loans
of such Swingline Lender, may exceed such Swingline Lender's Swingline
Commitment, provided, that in no event shall the aggregate outstanding principal
amount of the Swingline Loans exceed the aggregate Swingline Commitments then in
effect. Each Quoted Swingline Loan shall be made only by the Swingline Lender
furnishing the relevant Quoted Swingline Rate. Each ABR Swingline Loan shall be
made by the Swingline Lenders ratably in accordance with their respective
Swingline Percentages. The Swingline Loans shall be made in a minimum aggregate
principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess
thereof (or an aggregate principal amount equal to the remaining balance of the
available Swingline Commitments). Each Swingline Lender shall make the portion
of each Swingline Loan to be made by it available to any Swingline Borrower by
means of a credit to the general deposit account of such Swingline Borrower with
the Administrative Agent or a wire transfer, at the expense of such Swingline
Borrower, to an account designated in writing by such Swingline Borrower, in
each case by 3:30 p.m., New York City time, on the date such Swingline Loan is
requested to be made pursuant to paragraph (b) below, in immediately available
funds. Each Swingline Borrower may borrow, prepay and reborrow Swingline Loans
on or after the Closing Date and prior to the Revolving Credit Maturity Date (or
such earlier date on which the Commitments shall terminate in accordance
herewith) on the terms and subject to the conditions and limitations set forth
herein.

         (b) The relevant Swingline Borrower shall give the Administrative Agent
telephonic, written or telecopy notice substantially in the form of Exhibit B-5
(in the case of telephonic notice, such notice shall be promptly confirmed by
telecopy) no later than 2:30 p.m., New York City time (or, in the case of a
proposed Quoted Swingline Loan, 12:00 noon, New York City time), on the day of a
proposed Swingline Loan. Such notice shall be delivered on a Business Day, shall
be irrevocable (subject, in the case of Quoted Swingline Loans, to receipt by
the relevant Swingline Borrower of Quoted Swingline Rates acceptable to it) and
shall refer to this Agreement and shall specify the requested date (which shall
be a Business Day) and amount of such Swingline Loan. The Administrative Agent
shall promptly advise the Swingline Lenders of any notice received from any
Swingline Borrower pursuant to this paragraph (b). In the event that a Swingline
Borrower accepts a Quoted Swingline Rate in respect of a proposed Quoted
Swingline Loan, it shall notify the Administrative Agent (which shall in turn
notify the relevant Swingline Lender) of such acceptance no later than 2:30
p.m., New York City time, on the relevant borrowing date.

                                                                              24


         (c) In the event that any ABR Swingline Loan shall be outstanding for
more than five Business Days, the Administrative Agent shall, on behalf of the
relevant Swingline Borrower (which hereby irrevocably directs and authorizes the
Administrative Agent to act on its behalf), request each Lender, including the
Swingline Lenders, to make an ABR Revolving Credit Loan in an amount equal to
such Lender's Revolving Credit Percentage of the principal amount of such ABR
Swingline Loan. Each Lender will make the proceeds of its Revolving Credit Loan
available to the Administrative Agent for the account of the Swingline Lenders
at the office of the Administrative Agent prior to 12:00 Noon, New York City
time, in funds immediately available on the Business Day next succeeding the
date such notice is given. The proceeds of such Revolving Credit Loans shall be
immediately applied to repay the ABR Swingline Loans.

         (d) If, for any reason, Revolving Credit Loans may not be (as
determined by the Administrative Agent in its sole discretion), or are not, made
pursuant to Section 2.6(c) to repay ABR Swingline Loans as required by said
Section, then, effective on the date such Revolving Credit Loans would otherwise
have been made, each Lender severally, unconditionally and irrevocably agrees
that it shall purchase an undivided participating interest in such ABR Swingline
Loans ("Unrefunded Swingline Loans") in an amount equal to the amount of the
Revolving Credit Loan which otherwise would have been made by such Lender
pursuant to Section 2.6(c), which purchase shall be funded by the time such
Revolving Credit Loan would have been required to be made pursuant to Section
2.6(c). In the event that the Lenders purchase undivided participating interests
pursuant to the first sentence of this paragraph (d), each Lender shall
immediately transfer to the Administrative Agent, for the account of the
Swingline Lenders, in immediately available funds, the amount of its
participation. Any Lender holding a participation in an Unrefunded Swingline
Loan may exercise any and all rights of banker's lien, setoff or counterclaim
with respect to any and all moneys owing by the relevant Swingline Borrower to
such Lender by reason thereof as fully as if such Lender had made a Loan
directly to such Swingline Borrower in the amount of such participation.

         (e) Whenever, at any time after any Swingline Lender has received from
any Lender such Lender's participating interest in an ABR Swingline Loan, such
Swingline Lender receives any payment on account thereof, such Swingline Lender
will promptly distribute to such Lender its participating interest in such
amount (appropriately adjusted, in the case of interest payments, to reflect the
period of time during which such Lender's participating interest was outstanding
and funded); provided, however, that in the event that such payment received by
such Swingline Lender is required to be returned, such Lender will return to
such Swingline Lender any portion thereof previously distributed by such
Swingline Lender to it.

         (f) Notwithstanding anything to the contrary in this Agreement, each
Lender's obligation to make the Revolving Credit Loans referred to in Section
2.6(c) and to purchase and fund participating interests pursuant to Section
2.6(d) shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation, (i) any setoff, counterclaim,
recoupment, defense or other right which such Lender or any Swingline Borrower
may have against any Swingline Lender, any Swingline Borrower or any other
Person for any reason whatsoever; (ii) the occurrence or continuance of a
Default or an Event of Default or the failure to satisfy any of the conditions
specified in Article IV; (iii) any adverse change in the condition (financial or
otherwise) of CBS or any of its Subsidiaries; (iv) any breach of this Agreement
by any Borrower or any Lender; or (v) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing.

         (g) Upon written or telecopy notice to the Swingline Lenders and to the
Administrative Agent, CBS may at any time terminate, from time to time in part
reduce, or from time to time (with the
<PAGE>   29
                                                                              25


approval of the relevant Swingline Lender) increase, the Swingline Commitment of
any Swingline Lender. At any time when there shall be fewer than ten Swingline
Lenders, CBS may appoint from among the Lenders a new Swingline Lender, subject
to the prior consent of such new Swingline Lender and prior notice to the
Administrative Agent, so long as at no time shall there be more than ten
Swingline Lenders. Notwithstanding anything to the contrary in this Agreement,
(i) if any ABR Swingline Loans shall be outstanding at the time of any
termination, reduction, increase or appointment pursuant to the preceding two
sentences, the Swingline Borrowers shall on the date thereof prepay or borrow
ABR Swingline Loans to the extent necessary to ensure that at all times the
outstanding ABR Swingline Loans held by the Swingline Lenders shall be pro rata
according to the respective Swingline Commitments of the Swingline Lenders and
(ii) in no event may the aggregate Swingline Commitments exceed $300,000,000. On
the date of any termination or reduction of the Swingline Commitments pursuant
to this paragraph (g), the Swingline Borrowers shall pay or prepay so much of
the Swingline Loans as shall be necessary in order that, after giving effect to
such termination or reduction, (i) the aggregate outstanding principal amount of
the ABR Swingline Loans of any Swingline Lender will not exceed the Swingline
Commitment of such Swingline Lender and (ii) the aggregate outstanding principal
amount of all Swingline Loans will not exceed the aggregate Swingline
Commitments.

         (h) Each Swingline Borrower may prepay any Swingline Loan in whole or
in part at any time without premium or penalty; provided that such Swingline
Borrower shall have given the Administrative Agent written or telecopy notice
(or telephone notice promptly confirmed in writing or by telecopy) of such
prepayment not later than 10:30 a.m., New York City time, on the Business Day
designated by such Swingline Borrower for such prepayment; and provided further
that each partial payment shall be in an amount that is an integral multiple of
$1,000,000. Each notice of prepayment under this paragraph (h) shall specify the
prepayment date and the principal amount of each Swingline Loan (or portion
thereof) to be prepaid, shall be irrevocable and shall commit such Swingline
Borrower to prepay such Swingline Loan (or portion thereof) by the amount stated
therein on the date stated therein. All prepayments under this paragraph (h)
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment. Each payment of principal of or interest on ABR
Swingline Loans shall be allocated, as between the Swingline Lenders, pro rata
in accordance with their respective Swingline Percentages.

         SECTION 2.7. Letters of Credit. (a) Subject to the terms and
conditions hereof and relying upon the representations and warranties herein set
forth, each Issuing Lender agrees, at any time and from time to time on or after
the Closing Date until the earlier of (i) the tenth Business Day preceding the
Revolving Credit Maturity Date and (ii) the termination of the Commitments in
accordance with the terms hereof, to issue and deliver or to extend the expiry
of Letters of Credit for the account of CBS in an aggregate outstanding undrawn
amount which does not exceed the maximum amount specified in the applicable
Issuing Lender Agreement; provided that in no event shall the Aggregate LC
Exposure exceed $750,000,000 at any time. Each Letter of Credit (i) shall be in
a form approved in writing by CBS and the applicable Issuing Lender and (ii)
shall permit drawings upon the presentation of such documents as shall be
specified by CBS in the applicable notice delivered pursuant to paragraph (c)
below. The Lenders agree that, subject to compliance with the conditions
precedent set forth in Section 4.3, any Designated Letter of Credit may be
designated as a Letter of Credit hereunder from time to time on or after the
Closing Date pursuant to the procedures specified in the definition of
"Designated Letters of Credit".

         (b) Each Letter of Credit shall by its terms expire not later than the
fifth Business Day preceding the Revolving Credit Maturity Date. Any Letter of
Credit may provide for the renewal thereof for additional periods (which shall
in no event extend beyond the date referred to in the preceding
<PAGE>   30
                                                                              26


sentence). Each Letter of Credit shall by its terms provide for payment of
drawings in Dollars or in a Foreign Currency, provided that a Letter of Credit
denominated in a Foreign Currency may not be issued if, after giving effect
thereto, the Dollar equivalent of the aggregate face amount of all Letters of
Credit denominated in Foreign Currencies then outstanding would exceed
$150,000,000, as determined by the Administrative Agent.

         (c) CBS shall give the applicable Issuing Lender and the Administrative
Agent written or telecopy notice not later than 10:00 a.m., New York City time,
five Business Days (or such shorter period as shall be acceptable to such
Issuing Lender) prior to any proposed issuance of a Letter of Credit. Each such
notice shall refer to this Agreement and shall specify (i) the date on which
such Letter of Credit is to be issued (which shall be a Business Day) and the
face amount of such Letter of Credit, (ii) the name and address of the
beneficiary, (iii) whether such Letter of Credit is a Financial Letter of Credit
or a Non-Financial Letter of Credit (subject to confirmation of such status by
the Administrative Agent), (iv) whether such Letter of Credit shall permit a
single drawing or multiple drawings, (v) the form of the documents required to
be presented at the time of any drawing (together with the exact wording of such
documents or copies thereof), (vi) the expiry date of such Letter of Credit
(which shall conform to the provisions of paragraph (b) above) and (vii) if such
Letter of Credit is to be in a Foreign Currency, the relevant Foreign Currency.
The Administrative Agent shall give to each Lender prompt written or telecopy
advice of the issuance of any Letter of Credit. Each determination by the
Administrative Agent as to whether or not a Letter of Credit constitutes a
Financial Letter of Credit shall be conclusive and binding upon CBS and the
Lenders.

         (d) By the issuance of a Letter of Credit and without any further
action on the part of the applicable Issuing Lender or the Lenders in respect
thereof, the applicable Issuing Lender hereby grants to each Lender, and each
Lender hereby acquires from such Issuing Lender, a participation in such Letter
of Credit equal to such Lender's Revolving Credit Percentage at the time of any
drawing thereunder of the face amount of such Letter of Credit, effective upon
the issuance of such Letter of Credit. In addition, the applicable Issuing
Lender hereby grants to each Lender, and each Lender hereby acquires from such
Issuing Lender, a participation in each Designated Letter of Credit equal to
such Lender's Revolving Credit Percentage at the time of any drawing thereunder
of the face amount of such Designated Letter of Credit, effective on the date
such Designated Letter of Credit is designated as a Letter of Credit hereunder.
In consideration and in furtherance of the foregoing, each Lender hereby
absolutely and unconditionally agrees to pay to the Administrative Agent, for
the account of each Issuing Lender, in accordance with paragraph (f) below, such
Lender's Revolving Credit Percentage of each unreimbursed LC Disbursement made
by such Issuing Lender; provided, however, that the Lenders shall not be
obligated to make any such payment with respect to any payment or disbursement
made under any Letter of Credit to the extent resulting from the gross
negligence or wilful misconduct of such Issuing Lender.

         (e) Each Lender acknowledges and agrees that its acquisition of
participations pursuant to paragraph (d) above in respect of Letters of Credit
shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation, (i) any setoff, counterclaim,
recoupment, defense or other right which such Lender or CBS may have against any
Issuing Lender, CBS or any other Person for any reason whatsoever; (ii) the
occurrence or continuance of a Default or an Event of Default or the failure to
satisfy any of the conditions specified in Article IV; (iii) any adverse change
in the condition (financial or otherwise) of CBS or any of its Subsidiaries;
(iv) any breach of this Agreement by CBS or any Lender; or (v) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing.

                                                                              27


         (f) On the date on which it shall have ascertained that any documents
presented under a Letter of Credit appear to be in conformity with the terms and
conditions of such Letter of Credit, the applicable Issuing Lender shall give
written or telecopy notice to CBS and the Administrative Agent of the amount of
the drawing and the date on which payment thereon has been or will be made. If
the applicable Issuing Lender shall not have received from CBS the payment
required pursuant to paragraph (g) below by 12:00 noon, New York City time, two
Business Days after the date on which payment of a draft presented under any
Letter of Credit has been made, such Issuing Lender shall so notify the
Administrative Agent, which shall in turn promptly notify each Lender,
specifying in the notice to each Lender such Lender's Revolving Credit
Percentage of such LC Disbursement. Each Lender shall pay to the Administrative
Agent, not later than 2:00 p.m., New York City time, on such second Business
Day, such Lender's Revolving Credit Percentage of such LC Disbursement (which
obligation shall be expressed in Dollars only), which the Administrative Agent
shall promptly pay to the applicable Issuing Lender. The Administrative Agent
will promptly remit to each Lender such Lender's Revolving Credit Percentage of
any amounts subsequently received by the Administrative Agent from CBS in
respect of such LC Disbursement; provided that (i) amounts so received for the
account of any Lender prior to payment by such Lender of amounts required to be
paid by it hereunder in respect of any LC Disbursement and (ii) amounts
representing interest at the rate provided in paragraph (g) below on any LC
Disbursement for the period prior to the payment by such Lender of such amounts
shall in each case be remitted to the applicable Issuing Lender.

         (g) If an Issuing Lender shall pay any draft presented under a Letter
of Credit, CBS shall pay to such Issuing Lender an amount equal to the amount of
such draft before 12:00 noon, New York City time, on the second Business Day
immediately following the date of payment of such draft, together with interest
(if any) on such amount at a rate per annum equal to the interest rate in effect
for ABR Loans (or, in the case of Foreign Currency-denominated Letters of
Credit, the rate which would reasonably and customarily be charged by such
Issuing Lender on outstanding loans denominated in the relevant Foreign
Currency) from (and including) the date of payment of such draft to (but
excluding) the date on which either CBS shall have repaid, or the Lenders shall
have refunded, such draft in full (which interest shall be payable on such
second Business Day and from time to time thereafter on demand until either CBS
shall have repaid, or the Lenders shall have refunded, such draft in full). In
the event that such drawing shall be refunded by the Lenders as provided in
Section 2.7(f), CBS shall pay to the Administrative Agent, for the account of
the Lenders, quarterly on the last day of each March, June, September and
December, interest on the amount so refunded at a rate per annum equal to the
interest rate in effect for ABR Loans from (and including) the date of such
refunding to (but excluding) the date on which the amount so refunded by the
Lenders shall have been paid in full in Dollars by CBS. Each payment made to an
Issuing Lender by CBS pursuant to this paragraph shall be made at such Issuing
Lender's address for notices specified herein in lawful money of (x) the United
States of America (in the case of payments made on Dollar-denominated Letters of
Credit) or (y) the applicable foreign jurisdiction (in the case of payments on
Foreign Currency-denominated Letters of Credit) and in immediately available
funds. The obligation of CBS to pay the amounts referred to above in this
paragraph (g) (and the obligations of the Lenders under paragraphs (d) and (f)
above) shall be absolute, unconditional and irrevocable and shall be satisfied
strictly in accordance with their terms irrespective of:

                  (i) any lack of validity or enforceability of any Letter of
         Credit or any Issuing Lender Agreement or of the obligations of CBS
         under this Agreement or any Issuing Lender Agreement;

                  (ii) the existence of any claim, setoff, defense or other
         right which CBS or any other Person may at any time have against the
         beneficiary under any Letter of Credit, the Agents, any
<PAGE>   32

         Issuing Lender or any Lender (other than the defense of payment in
         accordance with the terms of this Agreement or a defense based on the
         gross negligence or wilful misconduct of the applicable Issuing Lender)
         or any other Person in connection with this Agreement or any other
         transaction;

                  (iii) any draft or other document presented under a Letter of
         Credit proving to be forged, fraudulent or invalid in any respect or
         any statement therein being untrue or inaccurate in any respect;
         provided that payment by the applicable Issuing Lender under such
         Letter of Credit against presentation of such draft or document shall
         not have constituted gross negligence or wilful misconduct;

                  (iv) payment by the applicable Issuing Lender under a Letter
         of Credit against presentation of a draft or other document which does
         not comply in any immaterial respect with the terms of such Letter of
         Credit; provided that such payment shall not have constituted gross
         negligence or wilful misconduct; or

                  (v) any other circumstance or event whatsoever, whether or not
         similar to any of the foregoing; provided that such other circumstance
         or event shall not have been the result of gross negligence or wilful
         misconduct of the applicable Issuing Lender.

         It is understood that in making any payment under a Letter of Credit
(x) such Issuing Lender's exclusive reliance on the documents presented to it
under such Letter of Credit as to any and all matters set forth therein,
including reliance on the amount of any draft presented under such Letter of
Credit, whether or not the amount due to the beneficiary thereof equals the
amount of such draft and whether or not any document presented pursuant to such
Letter of Credit proves to be forged, fraudulent or invalid in any respect, if
such document on its face appears to be in order, and whether or not any other
statement or any other document presented pursuant to such Letter of Credit
proves to be forged or invalid or any statement therein proves to be inaccurate
or untrue in any respect whatsoever, and (y) any noncompliance in any immaterial
respect of the documents presented under a Letter of Credit with the terms
thereof shall, in either case, not, in and of itself, be deemed wilful
misconduct or gross negligence of such Issuing Lender.

         (h) (i) Notwithstanding anything to the contrary contained in this
Agreement, for purposes of calculating any LC Fee or Commitment Fee payable in
respect of any Business Day, the Administrative Agent shall convert the amount
available to be drawn under any Letter of Credit denominated in Foreign Currency
into an amount of Dollars based upon the relevant Foreign Exchange Rate in
effect for such day. If on any date the Administrative Agent shall notify CBS
that, by virtue of any change in the Foreign Exchange Rate of any Foreign
Currency in which a Letter of Credit is denominated, the Total Facility Exposure
shall exceed the Total Commitment then in effect, then, within three Business
Days after the date of such notice, CBS shall prepay the Revolving Credit Loans
and/or the Swingline Loans to the extent necessary to eliminate such excess.
Each Issuing Lender which has issued a Letter of Credit denominated in a Foreign
Currency agrees to notify the Administrative Agent of the average daily
outstanding amount thereof for any period in respect of which LC Fees or
Commitment Fees are payable and, upon request by the Administrative Agent, for
any other date or period. For all purposes of this Agreement, determinations by
the Administrative Agent of the Dollar equivalent of any amount expressed in a
Foreign Currency shall be made on the basis of Foreign Exchange Rates reset
monthly (or on such other periodic basis as shall be selected by the
Administrative Agent in its sole discretion) and shall in each case be
conclusive absent manifest error.

                  (ii) Notwithstanding anything to the contrary contained in
         this Section 2.7, prior to demanding any reimbursement from the Lenders
         pursuant to Section 2.7(f) in respect of any Letter of Credit
         denominated in a Foreign Currency, the relevant Issuing Lender shall
         convert CBS's obligation under Section 2.7(g) to reimburse such Issuing
         Lender in such Foreign Currency into an obligation to reimburse such
         Issuing Lender (and, in turn, the Lenders) in Dollars. The amount of
         any such converted obligation shall be computed based upon the relevant
         Foreign Exchange Rate (as quoted by the Administrative Agent to such
         Issuing Lender) in effect for the day on which such conversion occurs.

         SECTION 2.8. Conversion and Continuation Options. (a) The relevant
Borrower may elect from time to time to convert Eurodollar Revolving Credit
Loans (or, subject to Section 2.10(f), a portion thereof) to ABR Revolving
Credit Loans on the last day of an Interest Period with respect thereto by
giving the Administrative Agent prior irrevocable notice of such election. The
relevant Borrower may elect from time to time to convert ABR Revolving Credit
Loans (subject to Section 2.10(f)) to Eurodollar Revolving Credit Loans by
giving the Administrative Agent at least three Business Days' prior irrevocable
notice of such election. Any such notice of conversion to Eurodollar Revolving
Credit Loans shall specify the length of the initial Interest Period therefor.
Upon receipt of any such notice the Administrative Agent shall promptly notify
each Lender thereof. All or any part of outstanding Eurodollar Revolving Credit
Loans and ABR Revolving Credit Loans may be converted as provided herein,
provided that no Revolving Credit Loan may be converted into a Eurodollar
Revolving Credit Loan when any Event of Default has occurred and is continuing
and the Administrative Agent has or the Required Lenders have determined in its
or their sole discretion not to permit such a conversion.

         (b) Any Eurodollar Revolving Credit Loans (or, subject to Section
2.10(f), a portion thereof) may be continued as such upon the expiration of the
then current Interest Period with respect thereto by the relevant Borrower
giving irrevocable notice to the Administrative Agent, not less than three
Business Days prior to the last day of the then current Interest Period with
respect thereto, of the length of the next Interest Period to be applicable to
such Revolving Credit Loans, provided that no Eurodollar Revolving Credit Loan
may be continued as such when any Event of Default has occurred and is
continuing and the Administrative Agent has or the Required Lenders have
determined in its or their sole discretion not to permit such a continuation,
and provided, further, that if the relevant Borrower shall fail to give any
required notice as described above in this paragraph or if such continuation is
not permitted pursuant to the preceding proviso such Eurodollar Revolving Credit
Loans shall be automatically converted to ABR Revolving Credit Loans on the last
day of such then expiring Interest Period. Upon receipt of any notice from a
Borrower pursuant to this Section 2.8(b), the Administrative Agent shall
promptly notify each Lender thereof.

         SECTION 2.9. Fees. (a) CBS agrees to pay to the Administrative Agent
for the account of each Lender a Commitment Fee for the period from and
including the Original Closing Date to the Revolving Credit Maturity Date (or
such earlier date on which the Commitments shall terminate in accordance
herewith), computed at a per annum rate equal to the Applicable Commitment Fee
Rate on the average daily Commitment Fee Calculation Amount in respect of such
Lender during the period for which payment is made. All Commitment Fees shall be
computed on the basis of the actual number of days elapsed in a year of 360 days
and shall be payable quarterly in arrears on the last day of each March, June,
September and December, on the Revolving Credit Maturity Date or such earlier
date on which the Commitments shall be terminated, commencing on the first of
such dates to occur after the Original Closing Date.

         (b) CBS agrees to pay each Lender, through the Administrative Agent, on
the last day of each March, June, September and December and on the Revolving
Credit Maturity Date or the date on which the Commitment of such Lender shall be
terminated as provided herein and all Letters of Credit
<PAGE>   34
                                                                              30


issued hereunder shall have expired, a letter of credit fee (an "LC Fee")
computed at a per annum rate equal to the Applicable LC Fee Rate on such
Lender's Revolving Credit Percentage of the average daily undrawn amount of the
Financial Letters of Credit or Non-Financial Letters of Credit, as the case may
be, outstanding during the preceding quarter (or shorter period commencing with
the Original Closing Date or ending with the Revolving Credit Maturity Date or
the date on which the Commitment of such Lender shall have been terminated and
all Letters of Credit issued hereunder shall have expired). All LC Fees shall be
computed on the basis of the actual number of days elapsed in a year of 360
days.

         (c) CBS and Infinity, jointly and severally, agree to pay, without
duplication, to the Administrative Agent, for its own account, the
administrative agent's fees ("Administrative Agent's Fees") provided for in the
Administrative Agent Fee Letter at the times provided therein.

         (d) CBS agrees to pay to each Issuing Lender, through the
Administrative Agent, for its own account, the applicable Issuing Lender Fees.

         (e) All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the relevant Lenders or to the Issuing Lenders. Once paid, none of the
Fees shall be refundable under any circumstances (other than corrections of
errors in payment).

         SECTION 2.10. Interest on Loans; Eurodollar Tranches; Etc. (a) Subject
to the provisions of Section 2.11, Eurodollar Loans shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to (i) in the case of each Eurodollar Revolving
Credit Loan, the Eurodollar Rate for the Interest Period in effect for such Loan
plus the Applicable Eurodollar Margin and (ii) in the case of each Eurodollar
Competitive Loan, the Eurodollar Rate for the Interest Period in effect for such
Loan plus the Margin offered by the Lender making such Loan and accepted by the
relevant Borrower pursuant to Section 2.3. The Eurodollar Rate for each Interest
Period shall be determined by the Administrative Agent, and such determination
shall be conclusive absent manifest error. The Administrative Agent shall
promptly advise the relevant Borrower and each Lender of such determination.

         (b) Subject to the provisions of Section 2.11, ABR Loans shall bear
interest (computed on the basis of the actual number of days elapsed over a year
of 365 or 366 days, as the case may be, when determined by reference to the
Prime Rate and over a year of 360 days at all other times) at a rate per annum
equal to the Alternate Base Rate. The Alternate Base Rate shall be determined by
the Administrative Agent, and such determination shall be conclusive absent
manifest error.

         (c) Subject to the provisions of Section 2.11, Quoted Swingline Loans
shall bear interest (computed on the basis of the actual number of days elapsed
over a year of 360 days) at a rate per annum equal to the relevant Quoted
Swingline Rate.

         (d) Subject to the provisions of Section 2.11, each Absolute Rate Loan
shall bear interest at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 360 days) equal to the fixed rate of
interest offered by the Lender making such Loan and accepted by the relevant
Borrower pursuant to Section 2.3.

         (e) Interest on each Loan shall be payable on each applicable Interest
Payment Date.

                                                                              31


         (f) Notwithstanding anything to the contrary in this Agreement, all
borrowings, conversions, continuations, repayments and prepayments of Eurodollar
Revolving Credit Loans hereunder and all selections of Interest Periods
hereunder in respect of Eurodollar Revolving Credit Loans shall be in such
amounts and shall be made pursuant to such elections so that, after giving
effect thereto, the aggregate principal amount of the Eurodollar Revolving
Credit Loans comprising each Eurodollar Tranche shall be equal to $50,000,000 or
a whole multiple of $5,000,000 in excess thereof. Unless otherwise agreed by the
Administrative Agent, in no event shall there be more than 25 Eurodollar
Tranches outstanding at any time.

         (g) If no election as to the Type of Revolving Credit Loan is specified
in any notice of borrowing with respect thereto, then the requested Loan shall
be an ABR Loan. If no Interest Period with respect to a Eurodollar Revolving
Credit Loan is specified in any notice of borrowing, conversion or continuation,
then the relevant Borrower shall be deemed to have selected an Interest Period
of one month's duration.

         SECTION 2.11. Default Interest. (a) If all or a portion of the
principal amount of any Loan shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), all outstanding Loans (whether or not
overdue) shall bear interest at a rate per annum which is equal to the rate that
would otherwise be applicable thereto pursuant to the provisions of Section 2.10
plus 2% and (b) if all or a portion of any LC Disbursement, any interest payable
on any Loan or LC Disbursement or any Fee or other amount payable hereunder
shall not be paid when due (whether at the stated maturity, by acceleration or
otherwise), such overdue amount shall bear interest at a rate per annum equal to
the rate otherwise applicable to ABR Loans pursuant to Section 2.10(b) plus 2%,
in each case, with respect to clauses (a) and (b) above, from the date of such
non-payment until such amount is paid in full (as well after as before
judgment).

         SECTION 2.12. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Loan (i) the Administrative Agent shall have
determined (which determination shall be conclusive and binding upon each
Borrower) that, by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining the Eurodollar Rate
for such Interest Period, or (ii) the Required Lenders shall have determined and
shall have notified the Administrative Agent that the Eurodollar Rate determined
or to be determined for such Interest Period will not adequately and fairly
reflect the cost to such Lenders (as conclusively certified by such Lenders) of
making or maintaining Eurodollar Loans during such Interest Period, the
Administrative Agent shall, as soon as practicable thereafter, give written or
telecopy notice of such determination to the Borrowers and the Lenders. In the
event of any such determination, until the Administrative Agent shall have
advised the Borrowers and the Lenders that the circumstances giving rise to such
notice no longer exist, (i) any request by a Borrower for a Eurodollar
Competitive Loan pursuant to Section 2.3 to be made after such determination
shall be of no force and effect and shall be denied by the Administrative Agent,
(ii) any request by a Borrower for a Eurodollar Revolving Credit Loan pursuant
to Section 2.4 to be made after such determination shall be deemed to be a
request for an ABR Loan and (iii) any request by a Borrower for conversion into
or a continuation of a Eurodollar Revolving Credit Loan pursuant to Section 2.8
to be made after such determination shall have no force and effect (in the case
of a requested conversion) or shall be deemed to be a request for a conversion
into an ABR Loan (in the case of a requested continuation). Also, in the event
of any such determination, the relevant Borrower shall be entitled, in its sole
discretion, if the requested Loan has not been made, to cancel its acceptance of
the Competitive Bids or to cancel its Competitive Bid Request relating thereto.
Each determination by the Administrative Agent or the Required Lenders hereunder
shall be conclusive absent manifest error.

                                                                              32


         SECTION 2.13. Termination and Reduction of Commitments. (a) Upon at
least three Business Days' prior irrevocable written or telecopy notice to the
Administrative Agent, CBS may at any time in whole permanently terminate, or
from time to time in part permanently reduce, the Commitments; provided,
however, that (i) each partial reduction of the Commitments shall be in a
minimum principal amount of $10,000,000 and in integral multiples of $1,000,000
in excess thereof and (ii) no such termination or reduction shall be made if,
after giving effect thereto and to any prepayments of the Loans made on the
effective date thereof, (x) the Outstanding Revolving Extensions of Credit of
any Lender would exceed such Lender's Commitment then in effect or (y) the Total
Facility Exposure would exceed the Total Commitment then in effect. The
Administrative Agent shall promptly advise the Lenders of any notice given
pursuant to this Section 2.13(a).

         (b) Except as otherwise provided in Section 2.21, each reduction in the
Commitments hereunder shall be made ratably among the Lenders in accordance with
their respective Commitments. CBS agrees to pay to the Administrative Agent for
the account of the Lenders, on the date of termination or reduction of the
Commitments, the Commitment Fees on the amount of the Commitments so terminated
or reduced accrued through the date of such termination or reduction.

         SECTION 2.14. Optional Prepayments of Revolving Credit Loans. The
relevant Borrower may at any time and from time to time prepay the Revolving
Credit Loans, in whole or in part, without premium or penalty, upon giving
irrevocable written or telecopy notice (or telephone notice promptly confirmed
by written or telecopy notice) to the Administrative Agent: (i) before 10:00
a.m., New York City time, three Business Days prior to prepayment, in the case
of Eurodollar Revolving Credit Loans, and (ii) before 10:00 a.m., New York City
time, one Business Day prior to prepayment, in the case of ABR Revolving Credit
Loans. Such notice shall specify the date and amount of prepayment and whether
the prepayment is of Eurodollar Revolving Credit Loans, ABR Revolving Credit
Loans or a combination thereof, and, if of a combination thereof, the amount
allocable to each. If a Eurodollar Revolving Credit Loan is prepaid on any day
other than the last day of the Interest Period applicable thereto, the relevant
Borrower shall also pay any amounts owing pursuant to Section 2.16. Upon receipt
of any such notice the Administrative Agent shall promptly notify each Lender
thereof. If any such notice is given, the amount specified in such notice shall
be due and payable on the date specified therein, together with (except in the
case of ABR Revolving Credit Loans) accrued interest to such date on the amount
prepaid. Partial prepayments of Revolving Credit Loans shall be in an aggregate
principal amount of $10,000,000 or a whole multiple of $1,000,000 in excess
thereof.

         SECTION 2.15. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision herein, if after the Original Closing Date
any change in applicable law or regulation (including any change in the reserve
percentages provided for in Regulation D) or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof shall change the basis of taxation of
payments to any Lender of the principal of or interest on any Eurodollar Loan or
Absolute Rate Loan made by such Lender (other than changes in respect of taxes
imposed on the overall net income of such Lender by the jurisdiction in which
such Lender has its principal office (or in which it holds any Eurodollar Loan
or Absolute Rate Loan) or by any political subdivision or taxing authority
therein and other than taxes that would not have been imposed but for the
failure of such Lender to comply with applicable certification, information,
documentation or other reporting requirements), or shall impose, modify or deem
applicable any reserve, special deposit or similar requirement against assets of
or deposits with or for the account of such Lender, or shall impose on such
Lender or the London interbank market any other condition affecting this
Agreement or any Eurodollar Loan or Absolute Rate Loan made by such Lender, and
the result of
<PAGE>   37
                                                                              33


any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan or Absolute Rate Loan or to reduce the amount of
any sum received or receivable by such Lender hereunder (whether of principal,
interest or otherwise) in respect of any Eurodollar Loan or Absolute Rate Loan
by an amount deemed by such Lender to be material, then the relevant Borrower
agrees to pay to such Lender as provided in paragraph (c) below such additional
amount or amounts as will compensate such Lender for such additional costs
incurred or reduction suffered. Notwithstanding the foregoing, no Lender shall
be entitled to request compensation under this paragraph with respect to any
Competitive Loan if the change giving rise to such request shall, or in good
faith should, have been taken into account in formulating the Competitive Bid
pursuant to which such Competitive Loan shall have been made.

         (b) If any Lender or any Issuing Lender shall have determined that the
adoption after the Original Closing Date of any law, rule, regulation or
guideline regarding capital adequacy, or any change in any law, rule, regulation
or guideline regarding capital adequacy or in the interpretation or
administration of any of the foregoing by any Governmental Authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Lender (or any lending office of such Lender) or
Issuing Lender or any Lender's or Issuing Lender's holding company with any
request or directive regarding capital adequacy (whether or not having the force
of law) of any such authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on such Lender's or Issuing
Lender's capital or on the capital of such Lender's or Issuing Lender's holding
company, if any, as a consequence of this Agreement or the Loans made by such
Lender or the LC Exposure of such Lender or Letters of Credit issued by such
Issuing Lender pursuant hereto to a level below that which such Lender or
Issuing Lender or such Lender's or Issuing Lender's holding company could have
achieved but for such applicability, adoption, change or compliance (taking into
consideration such Lender's or Issuing Lender's policies and the policies of
such Lender's or Issuing Lender's holding company with respect to capital
adequacy) by an amount deemed by such Lender or Issuing Lender to be material,
then from time to time CBS agrees to pay to such Lender or Issuing Lender as
provided in paragraph (c) below such additional amount or amounts as will
compensate such Lender or Issuing Lender or such Lender's or Issuing Lender's
holding company for any such reduction suffered.

         (c) A certificate of each Lender or Issuing Lender setting forth such
amount or amounts as shall be necessary to compensate such Lender or Issuing
Lender as specified in paragraph (a) or (b) above, as the case may be, and the
basis therefor in reasonable detail shall be delivered to the relevant Borrower
and shall be conclusive absent manifest error. The relevant Borrower shall pay
each Lender or Issuing Lender the amount shown as due on any such certificate
within 30 days after its receipt of the same. Upon the receipt of any such
certificate, the relevant Borrower shall be entitled, in its sole discretion, if
any requested Loan has not been made, to cancel its acceptance of the relevant
Competitive Bids or to cancel the Competitive Bid Request relating thereto,
subject to Section 2.16.

         (d) Except as provided in this paragraph, failure on the part of any
Lender to demand compensation for any increased costs or reduction in amounts
received or receivable or reduction in return on capital with respect to any
period shall not constitute a waiver of such Lender's right to demand
compensation with respect to any other period. The protection of this Section
2.15 shall be available to each Lender regardless of any possible contention of
the invalidity or inapplicability of the law, rule, regulation, guideline or
other change or condition which shall have occurred or been imposed so long as
it shall be customary for Lenders affected thereby to comply therewith. No
Lender shall be entitled to compensation under this Section 2.15 for any costs
incurred or reductions suffered with respect to any date unless it shall have
notified the relevant Borrower that it will demand compensation for such costs
<PAGE>   38
                                                                              34


or reductions under paragraph (c) above not more than 90 days after the later of
(i) such date and (ii) the date on which it shall have become aware of such
costs or reductions. Notwithstanding any other provision of this Section 2.15,
no Lender shall demand compensation for any increased cost or reduction referred
to above if it shall not at the time be the general policy or practice of such
Lender to demand such compensation in similar circumstances under comparable
provisions of other credit agreements, if any. In the event any Borrower shall
reimburse any Lender pursuant to this Section 2.15 for any cost and such Lender
shall subsequently receive a refund in respect thereof, such Lender shall so
notify such Borrower and, upon its request, will pay to such Borrower the
portion of such refund which such Lender shall determine in good faith to be
allocable to the cost so reimbursed. The covenants contained in this Section
2.15 shall survive the termination of this Agreement and the payment of the
Loans and all other amounts payable hereunder.

         SECTION 2.16. Indemnity. Each Borrower agrees to indemnify each Lender
against any loss or expense described below which such Lender may sustain or
incur as a consequence of (a) any failure by such Borrower to fulfill on the
date of any borrowing hereunder the applicable conditions set forth in Article
IV, (b) any failure by such Borrower to borrow, continue or convert any Loan
hereunder after irrevocable notice of such borrowing, continuation or conversion
has been given or deemed given or Competitive Bids have been accepted pursuant
to Article II or (c) any payment, prepayment or conversion of a Eurodollar Loan
or Absolute Rate Loan made to such Borrower required by any other provision of
this Agreement or otherwise made or deemed made, whatever the circumstances may
be that give rise to such payment, prepayment or conversion, or any transfer of
any such Loan pursuant to Section 2.21 or 9.4(b), on a date other than the last
day of the Interest Period applicable thereto. The loss or expense for which
such Lender shall be indemnified under this Section 2.16 shall be equal to the
excess, if any, as reasonably determined by such Lender, of (i) its cost of
obtaining the funds for the Loan being paid, prepaid, converted or not borrowed,
continued or converted (assumed to be the Eurodollar Rate in the case of
Eurodollar Loans) for the period from the date of such payment, prepayment,
conversion or failure to borrow, continue or convert to the last day of the
Interest Period for such Loan (or, in the case of a failure to borrow, continue
or convert, the Interest Period for such Loan which would have commenced on the
date of such failure) over (ii) the amount of interest (as reasonably determined
by such Lender) that would be realized by such Lender in reemploying the funds
so paid, prepaid, converted or not borrowed, continued or converted for such
period or Interest Period, as the case may be; provided, however, that such
amount shall not include any loss of a Lender's margin or spread over its cost
of obtaining funds as described above. A certificate of any Lender setting forth
any amount or amounts which such Lender is entitled to receive pursuant to this
Section 2.16 shall be delivered to the relevant Borrower and shall be conclusive
absent manifest error. This covenant shall survive the termination of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

         SECTION 2.17. Pro Rata Treatment; Funding Matters; Evidence of Debt.
(a) Except as required under Section 2.21, each payment or prepayment of
principal of any Revolving Credit Loan, each payment of interest on the
Revolving Credit Loans, each payment of the Commitment Fees pursuant to Section
2.9(a)(i), each payment of LC Fees, and each reduction of the Commitments, shall
be allocated pro rata among the Lenders in accordance with their respective
Commitments (or, if such Commitments shall have expired or been terminated, in
accordance with the respective principal amounts of their outstanding Revolving
Credit Loans). Each Lender agrees that in computing such Lender's portion of any
Loan to be made hereunder, the Administrative Agent may, in its discretion,
round such Lender's percentage of such Loan to the next higher or lower whole
Dollar amount.

         (b) Unless the Administrative Agent shall have received notice from a
Lender prior to the relevant borrowing date that such Lender will not make
available to the Administrative Agent such
<PAGE>   39
                                                                              35


Lender's portion of a borrowing, the Administrative Agent may assume that such
Lender has made such portion available to the Administrative Agent on the date
of such borrowing in accordance with this Agreement and the Administrative Agent
may, in reliance upon such assumption, make available to the relevant Borrower
on such date a corresponding amount. If and to the extent that such Lender shall
not have made such portion available to the Administrative Agent, each of such
Lender and the relevant Borrower agrees to repay to the Administrative Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to such Borrower until
the date such amount is repaid to the Administrative Agent at (i) in the case of
such Borrower, the interest rate applicable at the time to the relevant Loan and
(ii) in the case of such Lender, the Federal Funds Effective Rate. If such
Lender shall repay to the Administrative Agent such corresponding amount, such
amount shall constitute such Lender's Loan as part of such borrowing for the
purposes of this Agreement; provided that such repayment shall not release such
Lender from any liability it may have to such Borrower for the failure to make
such Loan at the time required herein.

         (c) The failure of any Lender to make any Loan shall not in itself
relieve any other Lender of its obligation to lend hereunder (it being
understood, however, that no Lender shall be responsible for the failure of any
other Lender to make any Loan required to be made by such other Lender).

         (d) Each Lender may at its option make any Eurodollar Loan by causing
any domestic or foreign branch or affiliate of such Lender to make such Loan;
provided that any exercise of such option shall not affect the obligation of the
relevant Borrower to repay such Loan in accordance with the terms of this
Agreement.

         (e) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness to such Lender resulting from
each Loan made by it from time to time, including the amounts of principal and
interest payable and paid to such Lender from time to time under this Agreement.
The Administrative Agent shall maintain accounts in which it will record (i) the
amount of each Loan made hereunder, the Borrower with respect to each Loan, the
Type of each Loan and each Interest Period, if any, applicable thereto, (ii) the
amount of any principal or interest due and payable or to become due and payable
from each Borrower to each Lender hereunder and (iii) the amount of any sum
received by the Administrative Agent hereunder from any Borrower and each
Lender's share thereof. The entries made in the accounts maintained pursuant to
this paragraph (e) shall, to the extent permitted by applicable law, be prima
facie evidence of the existence and amounts of the obligations therein recorded;
provided, however, that the failure of any Lender or the Administrative Agent to
maintain such accounts or any error therein shall not in any manner affect the
obligations of any Borrower to repay the Loans in accordance with their terms.

         (f) In order to expedite the transactions contemplated by this
Agreement, each Subsidiary Borrower shall be deemed, by its execution and
delivery of a Subsidiary Borrower Request, to have appointed CBS to act as agent
on behalf of such Subsidiary Borrower for the purpose of (a) giving any notices
contemplated to be given by such Subsidiary Borrower pursuant to this Agreement,
including, without limitation, borrowing notices, prepayment notices,
continuation notices, conversion notices, competitive bid requests and
competitive bid acceptances or rejections and (b) paying on behalf of such
Subsidiary Borrower any Subsidiary Borrower Obligations owing by such Subsidiary
Borrower; provided, that each Subsidiary Borrower shall retain the right, in its
discretion, to directly give any or all of such notices or make any or all of
such payments.

         (g) The Administrative Agent shall promptly notify the Lenders upon
receipt of any Subsidiary Borrower Designation and Subsidiary Borrower Request.
The Administrative Agent shall
<PAGE>   40
                                                                              36


promptly notify the Swingline Lenders upon receipt of any designation of a
Subsidiary Borrower as a Swingline Borrower.

         SECTION 2.18. Sharing of Setoffs. Except to the extent that this
Agreement provides for payments to be allocated to Revolving Credit Loans,
Swingline Loans or Competitive Loans, as the case may be, each Lender agrees
that if it shall, through the exercise of a right of banker's lien, setoff or
counterclaim against any Borrower, or pursuant to a secured claim under Section
506 of Title 11 of the United States Code or other security or interest arising
from, or in lieu of, such secured claim, received by such Lender under any
applicable bankruptcy, insolvency or other similar law or otherwise, or by any
other means (other than pursuant to any provision of this Agreement), obtain
payment (voluntary or involuntary) in respect of any category of its Loans or
such Lender's Revolving Credit Percentage of any LC Disbursement as a result of
which the unpaid principal portion of such Loans or the unpaid portion of such
Lender's Revolving Credit Percentage of the LC Disbursements shall be
proportionately less than the unpaid principal portion of such Loans or the
unpaid portion of the Revolving Credit Percentage of the LC Disbursements of any
other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in such Loans or the Revolving Credit
Percentage of the LC Disbursements of such other Lender, so that the aggregate
unpaid principal amount of such Loans and participations in such Loans held by
each Lender or the Revolving Credit Percentage of LC Disbursements and
participations in LC Disbursements held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all such Loans or LC
Disbursements then outstanding as the principal amount of such Loans or the
Revolving Credit Percentage of LC Disbursements of each Lender prior to such
exercise of banker's lien, setoff or counterclaim or other event was to the
principal amount of all such Loans or LC Disbursements outstanding prior to such
exercise of banker's lien, setoff or counterclaim or other event; provided,
however, that, if any such purchase or purchases or adjustments shall be made
pursuant to this Section 2.18 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. Any Lender holding a participation in a
Loan or LC Disbursement deemed to have been so purchased may exercise any and
all rights of banker's lien, setoff or counterclaim with respect to any and all
moneys owing by any Borrower to such Lender by reason thereof as fully as if
such Lender had made a Loan directly such Borrower or issued a Letter of Credit
for the account of CBS in the amount of such participation.

         SECTION 2.19. Payments. (a) Except as otherwise expressly provided
herein, each Borrower shall make each payment (including principal of or
interest on any Loan or any Fees or other amounts) hereunder without setoff or
counterclaim and shall make each such payment not later than 12:00 noon, New
York City time, on the date when due in Dollars to the Administrative Agent at
its offices at 60 Wall Street, New York, New York, in immediately available
funds.

         (b) Whenever any payment (including principal of or interest on any
Loan or any Fees or other amounts) hereunder shall become due, or otherwise
would occur, on a day that is not a Business Day, such payment may be made on
the next succeeding Business Day, and such extension of time shall in such case
be included in the computation of interest or Fees, if applicable.

         SECTION 2.20. Taxes. (a) Any and all payments by each Borrower
hereunder to or for the benefit of a Non-U.S. Person shall be made, in
accordance with Section 2.19, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto imposed by or on behalf
of the United States or any political subdivision thereof, excluding taxes
imposed on (or measured by) such Non-U.S. Person's net
<PAGE>   41
                                                                              37


income or net receipts, franchise taxes, taxes on doing business or taxes
imposed on capital or net worth (all such nonexcluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). If any Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder to a Non-U.S. Person, (i) the sum
payable shall be increased by the amount necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.20) such Non-U.S. Person shall receive an amount equal to
the sum it would have received had no such deductions been made, (ii) such
Borrower shall make such deductions and (iii) such Borrower shall pay the full
amount deducted to the relevant taxing authority or other Governmental Authority
in accordance with applicable law.

         (b) The relevant Borrower agrees to pay and reimburse on demand all
transfer, stamp, documentary or other similar taxes, assessments or charges
levied by any Governmental Authority in respect of this Agreement, any of the
Loans or the Letters of Credit (all such taxes, assessments or charges
hereinafter referred to as "Other Taxes").

         (c) The relevant Borrower will indemnify each Lender (or Transferee)
and the Administrative Agent for the full amount of Taxes and Other Taxes
(including any Taxes or Other Taxes imposed by the applicable jurisdiction on
amounts payable under this Section 2.20) paid by such Lender (or Transferee) or
the Administrative Agent, as the case may be, and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted by
the relevant taxing authority or other Governmental Authority. Such
indemnification shall be made within 30 days after the date such Lender (or
Transferee) or the Administrative Agent, as the case may be, makes written
demand therefor.

         (d) Within 30 days after the date of any payment of Taxes or Other
Taxes withheld by any Borrower in respect of any payment to a Non-U.S. Person,
such Borrower will furnish to the Administrative Agent, at its address referred
to in Section 9.1 for delivery to such Non-U.S. Person, the original or a
certified copy of a receipt (if available) evidencing payment thereof.

         (e) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.20 shall
survive the payment in full of the principal of and interest on all Loans made
hereunder and of all other amounts payable hereunder.

         (f) Each Lender (or Transferee) that is not a citizen or resident of
the United States of America, a corporation, partnership or other entity created
or organized in or under the laws of the United States of America, or any estate
or trust that is subject to federal income taxation regardless of the source of
its income (a "Non-U.S. Person") shall deliver to CBS and the Administrative
Agent (or, in the case of a participant, to the Lender from which the related
participation shall have been purchased) two copies of either U.S. Internal
Revenue Service Form 1001 or Form 4224, or, in the case of a Non-U.S. Person
claiming exemption from U.S. federal withholding tax under Section 871(h) or
881(c) of the Code with respect to payments of "portfolio interest", a Form W-8,
or any subsequent versions thereof or successors thereto (and, if such Non-U.S.
Person delivers a Form W-8, an annual certificate representing that such
Non-U.S. Person is not a "bank" for purposes of Section 881(c) of the Code, is
not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the
Code) of CBS and is not a controlled foreign corporation related to CBS (within
the meaning of Section 864(d)(4) of the Code)), properly completed and duly
executed by such Non-U.S. Person claiming complete exemption from U.S. federal
withholding tax on all payments by any Borrower under this Agreement. Such forms
shall be delivered by each Non-U.S. Person promptly after it becomes a party to
this Agreement (or, in the case of any participant, promptly after the date such
participant purchases the related participation). In addition,
<PAGE>   42
                                                                              38


each Non-U.S. Person shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Person. Each
Non-U.S. Person shall promptly notify CBS at any time it determines that it is
no longer in a position to provide any previously delivered certificate to CBS
(or any other form of certification adopted by the U.S. taxing authorities for
such purpose). Unless CBS and the Administrative Agent (or, in the case of a
participant, the Lender from which the related participation shall have been
purchased) have received forms or other documents satisfactory to them
indicating that payments hereunder are not subject to United States withholding
tax, the relevant Borrower or the Administrative Agent shall withhold taxes from
such payments at the applicable statutory rate in the case of payments of
interest to or for any Lender (or Transferee) that is a Non-U.S. Person.
Notwithstanding any other provision of this Section 2.20(f), a Non-U.S. Person
shall not be required to deliver any form pursuant to this Section 2.20(f) that
such Non-U.S. Person is not legally able to deliver by reason of the adoption of
any law, rule or regulation, or any change in any law, rule or regulation or in
the interpretation thereof, in each case occurring after the date such Non-U.S.
Person becomes a Lender (or Transferee).

         (g) No Borrower shall be required to pay any additional amounts to any
Non-U.S. Person in respect of United States withholding tax pursuant to
paragraph (a) above (i) if the obligation to pay such additional amounts would
not have arisen but for a failure by such Non-U.S. Person to comply with the
provisions of paragraph (f) above or (ii) in the case of a Transferee, to the
extent such additional amounts exceed the additional amounts that would have
been payable had no transfer or assignment to such Transferee occurred;
provided, however, that each Borrower shall be required to pay those amounts to
any Lender (or Transferee) that it was required to pay hereunder prior to the
failure of such Lender (or Transferee) to comply with the provisions of such
paragraph (f).

         SECTION 2.21. Termination or Assignment of Commitments Under Certain
Circumstances. (a) Any Lender (or Transferee) claiming any additional amounts
payable pursuant to Section 2.15 or Section 2.20 shall use reasonable efforts
(consistent with legal and regulatory restrictions) to file any certificate or
document requested by any Borrower or to change the jurisdiction of its
applicable lending office if the making of such a filing or change would avoid
the need for or reduce the amount of any such additional amounts which may
thereafter accrue and would not, in the sole determination of such Lender (or
Transferee), be otherwise disadvantageous to such Lender (or Transferee).

         (b) In the event that (x) any Lender shall have delivered a notice or
certificate pursuant to Section 2.15, (y) any Borrower shall be required to make
additional payments to any Lender under Section 2.20, or (z) any Lender (a
"Non-Consenting Lender") shall withhold its consent to any amendment described
in clause (i) or (ii) of Section 9.8(b) as to which consents have been obtained
from Lenders having Total Facility Percentages aggregating at least 90%, CBS
shall have the right, at its own expense, upon notice to such Lender (or
Lenders) and the Administrative Agent, (i) to terminate the Commitments of such
Lender (except in the case of clause (z) above) or (ii) to require such Lender
(or, in the case of clause (z) above, each Non-Consenting Lender) to transfer
and assign without recourse (in accordance with and subject to the restrictions
contained in Section 9.4) all its interests, rights and obligations under this
Agreement to one or more other financial institutions acceptable to the
Administrative Agent (which approval shall not be unreasonably withheld) which
shall assume such obligations; provided that (w) in the case of any replacement
of Non-Consenting Lenders, each assignee shall have consented to the relevant
amendment, (x) no such termination or assignment shall conflict with any law,
rule or regulation or order of any Governmental Authority, (y) the Borrowers or
the assignee (or assignees), as the case may be, shall pay to each affected
Lender in immediately available funds on the date of such termination or
assignment the principal of and interest accrued to the date of
<PAGE>   43
                                                                              39


payment on the Loans made by it hereunder and all other amounts accrued for its
account or owed to it hereunder and (z) CBS may not terminate Commitments
representing more than 10% of the original aggregate Commitments pursuant to
this paragraph (b).

                                  ARTICLE III.

                         REPRESENTATIONS AND WARRANTIES

         CBS hereby represents and warrants, and each Subsidiary Borrower by its
execution and delivery of a Subsidiary Borrower Request represents and warrants
(to the extent specifically applicable to such Subsidiary Borrower), to each of
the Lenders that:

         SECTION 3.1. Corporate Existence. Each of CBS and each Material
Subsidiary: (a) is a corporation, partnership or other entity duly organized and
validly existing under the laws of the jurisdiction of its organization; (b) has
all requisite corporate or other power, and has all material governmental
licenses, authorizations, consents and approvals, necessary to own its assets
and carry on its business as now being or as proposed to be conducted, except
where the failure to have any of the foregoing would not result in a Material
Adverse Effect; and (c) is qualified to do business in all jurisdictions in
which the nature of the business conducted by it makes such qualification
necessary and where failure so to qualify would result in a Material Adverse
Effect.

         SECTION 3.2. Financial Condition. (a) Each of (i) the consolidated
balance sheet of CBS and its Consolidated Subsidiaries as at December 31, 1998,
and the related consolidated statements of income and cash flows of CBS and its
Consolidated Subsidiaries for the fiscal year ended on such date, with the
opinion thereon of KPMG, LLP and (ii) the unaudited consolidated balance sheets
of CBS and its Consolidated Subsidiaries as at March 31, 1999 and as at June 30,
1999, and the related unaudited consolidated statements of income and cash flows
of CBS and its Consolidated Subsidiaries for the fiscal quarters ended on such
dates, all certified by a Financial Officer of CBS, heretofore furnished to each
of the Lenders, fairly present the consolidated financial condition of CBS and
its Consolidated Subsidiaries as at such dates and the consolidated results of
their operations for the fiscal year or fiscal quarter ended on such dates in
accordance with GAAP (subject, in the case of the statements referred to in
clause (ii) above, to year-end audit adjustments). Neither CBS nor any of its
Material Subsidiaries had on such dates any known material contingent liability,
except as referred to or reflected or provided for in the Exchange Act Report or
in such balance sheets (or the notes thereto) as at such dates.

         (b) There has been no material adverse change in the consolidated
financial condition, operations, assets, business or prospects taken as a whole
of CBS and its Consolidated Subsidiaries from that set forth in the consolidated
financial statements of CBS for the fiscal year ended December 31, 1995 referred
to in Section 3.2(a) (it being agreed, however, that none of (i) the reduction
by any rating agency of any rating assigned to Indebtedness of CBS, (ii)
non-cash provisions for loan losses and additions to valuation allowances, (iii)
any change in GAAP or compliance therewith and (iv) any legal or arbitral
proceedings which have been disclosed in the Exchange Act Report, whether
threatened, pending, resulting in a judgment or otherwise, prior to the time a
final judgment for the payment of money shall have been recorded against CBS or
any Material Subsidiary by any Governmental Authority having jurisdiction, and
the judgment is non-appealable (or the time for appeal has expired) and all
stays of execution have expired or been lifted shall, in and of itself,
constitute such a material adverse change).

         SECTION 3.3. Litigation. Except as disclosed to the Lenders in the
Exchange Act Report filed prior to the Closing Date or otherwise disclosed in
writing to the Lenders prior to the
<PAGE>   44
                                                                              40


Closing Date, there are no legal or arbitral proceedings, or any proceedings by
or before any Governmental Authority, pending or (to the knowledge of CBS)
threatened against CBS or any of its Material Subsidiaries which have resulted
in a Material Adverse Effect (it being agreed that any legal or arbitral
proceedings which have been disclosed in the Exchange Act Report, whether
threatened, pending, resulting in a judgment or otherwise, prior to the time a
final judgment for the payment of money shall have been recorded against CBS or
any Material Subsidiary by any Governmental Authority having jurisdiction, and
the judgment is non-appealable (or the time for appeal has expired) and all
stays of execution have expired or been lifted shall not, in and of itself, be
deemed to result in a Material Adverse Effect). The "Exchange Act Report" shall
mean, collectively, the Annual Report of each of CBS and Infinity on Form 10-K
and Form 10-K/A for the year ended December 31, 1998, each Report on Form 8-K of

         Subsidiary Borrower, in Article III, or in any certificate delivered
         pursuant hereto, shall be true and correct in all material respects on

         Outstanding Revolving Extensions of Credit of each Lender shall not
         exceed such Lender's Commitment then in effect and (ii) the Total
         Facility Exposure shall not exceed the Total Commitment then in effect.

         quarterly financial statements may be fulfilled by providing to the
         Lenders the report of CBS to the SEC on Form 10-Q for the applicable
         quarterly period, accompanied by the officer's certificate described in

                  4043(b) of ERISA and the regulations issued thereunder, with
                  respect to a Plan, as to which PBGC has not by regulation
                  waived the requirement of Section 4043(a) of ERISA that it be

         SECTION 5.2. Corporate Existence, Etc. CBS will, and will cause each of
its Material Subsidiaries to, preserve and maintain its legal existence and all

this Section 5.2 shall prohibit any transaction expressly permitted under
Section 5.4 and (b) CBS or such Material Subsidiary shall not be required to
preserve or maintain any such right, privilege or franchise if the Board of
Directors of CBS or such Material Subsidiary, as the case may be, shall

the conduct of the business of CBS or such Material Subsidiary, as the case may
be); comply with the requirements of all applicable laws, rules, regulations and
orders of Governmental Authorities (including, without limitation, all
Environmental Laws) and with all contractual obligations if failure to comply
with such requirements or obligations would reasonably be expected to result in
a Material Adverse Effect; pay and discharge all material taxes, assessments,
governmental charges, levies or other obligations of whatever nature imposed on
it or on its income or profits or on any of its Property prior to the date on
which penalties attach thereto, except for any such tax, assessment, charge,

and by proper proceedings and against which adequate reserves are being
maintained; maintain all its Property used or useful in its business in good
working order and condition, ordinary wear and tear excepted, all as in the
judgment of CBS or such Material Subsidiary may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times (provided that CBS or such Material Subsidiary shall not
be required to maintain any such Property if the failure to maintain any such
Property is, in the judgment of CBS or such Material Subsidiary, desirable in
the conduct of the business of CBS or such Material Subsidiary); keep proper
books of records and accounts in which entries that are full, true and correct
in all material respects shall be made in conformity with GAAP; and permit

business and affairs with its Financial Officers or their designees, all to the
extent reasonably requested by such Lender.

         SECTION 5.3. Insurance. CBS will, and will cause each of its Material
Subsidiaries to, keep insured by financially sound and reputable insurers all
Property of a character usually insured by corporations engaged in the same or
similar business and similarly situated against loss or damage of the kinds and
in the amounts consistent with prudent business practice and carry such other
insurance as is consistent with prudent business practice (it being understood
that self-insurance shall be permitted to the extent consistent with prudent
business practice).

         SECTION 5.4. Prohibition of Fundamental Changes. CBS will not, and will
not permit any of its Material Subsidiaries to (i) enter into any transaction of
merger, consolidation, liquidation or dissolution or (ii) Dispose of, in one
transaction or a series of related transactions, all or a substantial part
(determined by reference to CBS and its Subsidiaries taken as a whole) of its
business or Property, whether now owned or hereafter acquired (excluding (x)
financings by way of sales of receivables or inventory, (y) inventory or other
Property Disposed of in the ordinary course of business and (z) obsolete or
worn-out Property, tools or equipments no longer used or useful in its
business). Notwithstanding the foregoing provisions of this Section 5.4:

         or into: (i) CBS if CBS shall be the continuing or surviving
         corporation or (ii) any other such Subsidiary; provided that (x) if any
         such transaction shall be between a Subsidiary and a Wholly Owned

obligation (a "Lien Restriction") in connection with the incurrence of

by such Material Subsidiary (collectively, "Credit Obligations"), except (a)

receivables and (e) Lien Restrictions included in the Infinity Credit Agreement.
It is understood that an "equal and ratable" clause shall not be deemed to
constitute a Lien Restriction so long as such clause would permit the
obligations entitled to the benefit of such clause and the applicable Credit
Obligations to be secured by Liens on the relevant assets on a pari passu basis.

                                   ARTICLE VI.

         in any agreement or instrument evidencing or governing, any such
         Indebtedness in excess of $100,000,000 if the effect of any failure
         referred to in this clause (ii) (x) is to cause, or to permit the
         holder or holders of such Indebtedness or a trustee on its or their
         behalf to cause, such Indebtedness to become due prior to its stated
         maturity (provided that this subclause (ii)(x) shall not apply to any
         provision that permits the holders, or a trustee on their behalf, to
         cause Indebtedness to become due prior to its stated maturity because
         of the failure to deliver to such holders or such trustee financial
         statements or certificates for any Subsidiary that is not required by
         law or regulation to file financial statements with the SEC, unless
         such Indebtedness has become due prior to its stated maturity as a
         result of such failure) or (y) has caused such Indebtedness to become
         due prior to its stated maturity (it being agreed that for purposes of
         this paragraph (d) only (other than subclause (ii)(x) of this paragraph
         (d)), the term "Indebtedness"

         foreign currency exchange agreement or other interest or exchange rate
         hedging agreement and that the amount of any Person's obligations under
         any such agreement shall be the net amount that such Person could be
         required to pay as a result of a termination thereof by reason of a
         default thereunder);

                  (e) CBS or any of its Material Subsidiaries shall admit in
         writing its inability, or be generally unable, to pay its debts as such
         debts become due;

         in writing to, any petition filed against it in an involuntary case
         under the Bankruptcy Code, or (vi) take any corporate action for the
         purpose of effecting any of the foregoing;

                  (g) a proceeding or a case shall be commenced, without the
         application or consent of CBS or any of its Material Subsidiaries, in
         any court of competent jurisdiction, seeking (i) its liquidation,
         reorganization, dissolution or winding-up, or the composition or
         readjustment of its debts, (ii) the appointment of a trustee, receiver,
         custodian, liquidator or the like of CBS or such Material Subsidiary or
         of all or any substantial part of its assets or (iii) similar relief in
         respect of CBS or such Material Subsidiary under any law relating to
         bankruptcy, insolvency, reorganization, winding-up, or composition or
         adjustment of debts, and such proceeding or case shall continue
         undismissed, or an order, judgment or decree approving or ordering any
         of the foregoing shall be entered and continue unstayed and in effect,
         for a period of 60 or more days; or an order for relief against CBS or

         more courts, administrative tribunals or other bodies having
         jurisdiction against CBS and/or any of its Material Subsidiaries and
         the same shall not be paid or discharged (or provision shall not be
         made for such discharge), or a stay of execution thereof shall not be
         procured, within 60 days from the date of the date of entry thereof and
         CBS or the relevant Material Subsidiary shall not, within said period
         of 60 days, or such longer period during which execution of the same
         shall have been stayed, appeal therefrom and cause the execution
         thereof to be stayed during such appeal;

                  (i) an event or condition specified in Section 5.1(e) shall
         occur or exist with respect to any Plan or Multiemployer Plan and, as a
         result of such event or condition, together with all other such events
         or conditions, CBS or any ERISA Affiliate shall incur or in the good
         faith opinion of the Required Lenders shall be reasonably likely to
         incur a liability to a Plan, a Multiemployer Plan or PBGC (or any
         combination of the foregoing) which would constitute, in the good faith
         determination of the Required Lenders, a Material Adverse Effect;

                  (j) a Change of Control shall have occurred or, with respect
         to any period of 25 consecutive calendar months (whether commencing
         before or after the date of this Agreement), individuals who were
         directors of CBS on the first day of such period or who were nominated
         by
<PAGE>   57
                                                                              53


         such directors (or by directors in a direct chain of directors so
         nominated) shall no longer occupy a majority of the seats (other than
         vacant seats) on the Board of Directors of CBS (excluding by reason of
         the death or retirement of any director or by reason of the Viacom
         Merger); or

                  (k) The guarantee contained in Article VIII shall cease, for
         any reason, to be in full force and effect or CBS shall so assert;

then and in every such event (other than an event with respect to CBS described
in paragraph (f) or (g) above), and at any time thereafter during the
continuance of such event, the Administrative Agent may, and at the request of
the Required Lenders shall, by notice to CBS, take any or all of the following
actions, at the same or different times: (I) terminate forthwith the
Commitments, (II) declare the Loans then outstanding to be forthwith due and
payable in whole or in part, whereupon the principal of the Loans so declared to
be due and payable, together with accrued interest thereon and any unpaid
accrued Fees and all other liabilities of each Borrower accrued hereunder, shall
become forthwith due and payable, without presentment, demand, protest or any
other notice of any kind, all of which are hereby expressly waived by each
Borrower, anything contained herein to the contrary notwithstanding, and (III)
require that CBS deposit cash with the Administrative Agent, in an amount equal
to the Aggregate LC Exposure, as collateral security for the repayment of any
future LC Disbursements; and in any event with respect to any Borrower described
in paragraph (f) or (g) above, (A) if such Borrower is CBS, the Commitments
shall automatically terminate and the principal of the Loans then outstanding,
together with accrued interest thereon and any unpaid accrued Fees and all other
liabilities of each Borrower accrued hereunder, shall automatically become due
and payable and CBS shall be required to deposit cash with the Administrative
Agent, in an amount equal to the Aggregate LC Exposure, as collateral security
for the repayment of any future drawings under the Letters of Credit and (B) if
such Borrower is a Subsidiary Borrower, the principal of the Loans made to such
Subsidiary Borrower then outstanding, together with accrued interest thereon and
all other liabilities of such Subsidiary Borrower accrued hereunder, shall
automatically become due and payable, in each case without presentment, demand,
protest or any other notice of any kind, all of which are hereby expressly
waived by each Borrower, anything contained herein to the contrary
notwithstanding.

                                  ARTICLE VII.

                                   THE AGENTS

         In order to expedite the transactions contemplated by this Agreement,
each Agent is hereby appointed to act as Agent on behalf of the Lenders. Each of
the Lenders and the Issuing Lenders hereby irrevocably authorizes the
Administrative Agent to take such actions on its behalf and to exercise such
powers as are specifically delegated to the Administrative Agent by the terms
and provisions hereof, together with such actions and powers as are reasonably
incidental thereto. The Administrative Agent is hereby expressly authorized by
the Lenders and the Issuing Lenders, without hereby limiting any implied
authority, (a) to receive on behalf of the Lenders all payments of principal of
and interest on the Loans and the LC Disbursements and all other amounts due to
the Lenders and Issuing Lenders hereunder, and promptly to distribute to each
Lender and Issuing Lender its proper share of each payment so received; (b) to
give notice on behalf of each of the Lenders to the Borrowers of any Event of
Default specified in this Agreement of which the Administrative Agent has actual
knowledge acquired in connection with its agency hereunder; and (c) to
distribute to each Lender and Issuing Lender copies of all notices, financial
statements and other materials delivered by any Borrower pursuant to this
Agreement as received by the Administrative Agent.
<PAGE>   58
                                                                              54


         Neither any Agent nor any of its directors, officers, employees or
agents shall be liable as such for any action taken or omitted by any of them
except for its or his own gross negligence or wilful misconduct, or be
responsible for any statement, warranty or representation herein or the contents
of any document delivered in connection herewith, or be required to ascertain or
to make any inquiry concerning the performance or observance by any Borrower of
any of the terms, conditions, covenants or agreements contained in this
Agreement. The Agents shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements. The Administrative Agent shall in
all cases be fully protected in acting, or refraining from acting, in accordance
with written instructions signed by the Required Lenders (or, when expressly
required hereby, all the Lenders) and, except as otherwise specifically provided
herein, such instructions and any action or inaction pursuant thereto shall be
binding on all the Lenders and the Issuing Lenders. The Administrative Agent
shall, in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper Person or Persons. Neither the
Agents nor any of their directors, officers, employees or agents shall have any
responsibility to any Borrower on account of the failure of or delay in
performance or breach by any Lender or Issuing Lender of any of its obligations
hereunder or to any Lender or Issuing Lender on account of the failure of or
delay in performance or breach by any other Agent, any other Lender or Issuing
Lender or any Borrower of any of their respective obligations hereunder or in
connection herewith. The Administrative Agent may execute any and all duties
hereunder by or through agents or employees and shall be entitled to rely upon
the advice of legal counsel selected by it with respect to all matters arising
hereunder and shall not be liable for any action taken or suffered in good faith
by it in accordance with the advice of such counsel.

         The Lenders and the Issuing Lenders hereby acknowledge that the
Administrative Agent shall be under no duty to take any discretionary action
permitted to be taken by it pursuant to the provisions of this Agreement unless
it shall be requested in writing to do so by the Required Lenders.

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders, the Issuing Lenders and the Borrowers. Upon any such
resignation, the Required Lenders shall have the right to appoint from the
Lenders a successor. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Administrative Agent gives notice of its resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint from the
Lenders a successor Administrative Agent which shall be a bank with an office in
New York, New York, having a combined capital and surplus of at least
$500,000,000 or an affiliate of any such bank, which successor shall be
acceptable to CBS (such acceptance not to be unreasonably withheld). Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
bank, such successor shall succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Administrative Agent and the
retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. After the Administrative Agent's resignation hereunder,
the provisions of this Article and Section 9.5 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Administrative Agent.

         With respect to the Loans made by them and their LC Exposure hereunder,
the Agents in their individual capacity and not as Agents shall have the same
rights and powers as any other Lender and may exercise the same as though they
were not Agents, and the Agents and their affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Borrowers or
any of their respective Subsidiaries or any Affiliate thereof as if they were
not Agents.

                                                                              55


         Each Lender and Issuing Lender agrees (i) to reimburse the
Administrative Agent in the amount of its pro rata share (based on its Total
Facility Percentage or, after the date on which the Loans shall have been paid
in full, based on its Total Facility Percentage immediately prior to such date)
of any reasonable, out-of-pocket expenses incurred for the benefit of the
Lenders or the Issuing Lenders by the Administrative Agent, including reasonable
counsel fees and compensation of agents and employees paid for services rendered
on behalf of the Lenders or the Issuing Lenders, which shall not have been
reimbursed by or on behalf of any Borrower and (ii) to indemnify and hold
harmless the Administrative Agent and any of its directors, officers, employees
or agents, in the amount of such pro rata share, from and against any and all
liabilities, taxes, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by or asserted against it in its capacity as
Administrative Agent in any way relating to or arising out of this Agreement or
any action taken or omitted by it under this Agreement, to the extent the same
shall not have been reimbursed by or on behalf of CBS, provided that no Lender
or Issuing Lender shall be liable to the Administrative Agent or any such
director, officer, employee or agent for any portion of such liabilities, taxes,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the gross negligence or wilful
misconduct of the Administrative Agent or any of its directors, officers,
employees or agents.

         Each Lender and Issuing Lender acknowledges that it has, independently
and without reliance upon the Agents or any other Lender or Issuing Lender and
based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender and
Issuing Lender also acknowledges that it will, independently and without
reliance upon any Agent or any other Lender or Issuing Lender and based on such
documents and information as it shall from time to time deem appropriate,
continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any related agreement or any document furnished hereunder
or thereunder.

         Neither the Documentation Agent nor either Syndication Agent nor any
managing agent shall have any duties or responsibilities hereunder in its
capacity as such.

                                  ARTICLE VIII.

                                    GUARANTEE

         SECTION 8.1. Guarantee. In order to induce the Administrative Agent and
the Lenders to become bound by this Agreement and to make or maintain the Loans
hereunder, and in consideration thereof, CBS hereby unconditionally and
irrevocably guarantees, as primary obligor and not merely as surety, to the
Administrative Agent, for the ratable benefit of the Lenders, the prompt and
complete payment and performance by each Subsidiary Borrower when due (whether
at stated maturity, by acceleration or otherwise) of the Subsidiary Borrower
Obligations, and CBS further agrees to pay any and all expenses (including,
without limitation, all reasonable fees, charges and disbursements of counsel)
which may be paid or incurred by the Administrative Agent or by the Lenders in
enforcing, or obtaining advice of counsel in respect of, any of their rights
under the guarantee contained in this Article VIII. The guarantee contained in
this Article VIII, subject to Section 8.5, shall remain in full force and effect
until the Subsidiary Borrower Obligations are paid in full and the Commitments
are terminated, notwithstanding that from time to time prior thereto any
Subsidiary Borrower may be free from any Subsidiary Borrower Obligations.
<PAGE>   60
                                                                              56


         CBS agrees that whenever, at any time, or from time to time, it shall
make any payment to the Administrative Agent or any Lender on account of its
liability under this Article VIII, it will notify the Administrative Agent and
such Lender in writing that such payment is made under the guarantee contained
in this Article VIII for such purpose. No payment or payments made by any
Subsidiary Borrower or any other Person or received or collected by the
Administrative Agent or any Lender from any Subsidiary Borrower or any other
Person by virtue of any action or proceeding or any setoff or appropriation or
application, at any time or from time to time, in reduction of or in payment of
the Subsidiary Borrower Obligations shall be deemed to modify, reduce, release
or otherwise affect the liability of CBS under this Article VIII which,
notwithstanding any such payment or payments, shall remain liable for the unpaid
and outstanding Subsidiary Borrower Obligations until, subject to Section 8.5,
the Subsidiary Borrower Obligations are paid in full and the Commitments are
terminated.

         SECTION 8.2. No Subrogation, etc. Notwithstanding any payment or
payments made by CBS hereunder, or any set-off or application of funds of CBS by
the Administrative Agent or any Lender, CBS shall not be entitled to be
subrogated to any of the rights of the Administrative Agent or any Lender
against any Subsidiary Borrower or against any collateral security or guarantee
or right of offset held by the Administrative Agent or any Lender for the
payment of the Subsidiary Borrower Obligations, nor shall CBS seek or be
entitled to seek any contribution, reimbursement, exoneration or indemnity from
or against any Subsidiary Borrower in respect of payments made by CBS hereunder,
until all amounts owing to the Administrative Agent and the Lenders by the
Subsidiary Borrowers on account of the Subsidiary Borrower Obligations are paid
in full and the Commitments are terminated. So long as the Subsidiary Borrower
Obligations remain outstanding, if any amount shall be paid by or on behalf of
any Subsidiary Borrower or any other Person to CBS on account of any of the
rights waived in this Section 8.2, such amount shall be held by CBS in trust,
segregated from other funds of CBS, and shall, forthwith upon receipt by CBS, be
turned over to the Administrative Agent in the exact form received by CBS (duly
indorsed by CBS to the Administrative Agent, if required), to be applied against
the Subsidiary Borrower Obligations, whether matured or unmatured, in such order
as the Administrative Agent may determine.

         SECTION 8.3. Amendments, etc. with respect to the Subsidiary Borrower
Obligations. CBS shall remain obligated under this Article VIII notwithstanding
that, without any reservation of rights against CBS, and without notice to or
further assent by CBS, any demand for payment of or reduction in the principal
amount of any of the Subsidiary Borrower Obligations made by the Administrative
Agent or any Lender may be rescinded by the Administrative Agent or such Lender,
and any of the Subsidiary Borrower Obligations continued, and the Subsidiary
Borrower Obligations, or the liability of any other party upon or for any part
thereof, or any collateral security or guarantee therefor or right of offset
with respect thereto, may, from time to time, in whole or in part, be renewed,
extended, amended, modified, accelerated, compromised, waived, surrendered or
released by the Administrative Agent or any Lender, and this Agreement and any
other documents executed and delivered in connection herewith may be amended,
modified, supplemented or terminated, in whole or in part, as the Required
Lenders (or all Lenders, as the case may be) may deem advisable from time to
time, and any collateral security, guarantee or right of offset at any time held
by the Administrative Agent or any Lender for the payment of the Subsidiary
Borrower Obligations may be sold, exchanged, waived, surrendered or released.
Neither the Administrative Agent nor any Lender shall have any obligation to
protect, secure, perfect or insure any lien at any time held by it as security
for the Subsidiary Borrower Obligations or for the guarantee contained in this
Article VIII or any property subject thereto.

         SECTION 8.4. Guarantee Absolute and Unconditional. CBS waives any and
all notice of the creation, renewal, extension or accrual of any of the
Subsidiary Borrower Obligations and notice of or proof of reliance by the
Administrative Agent or any Lender upon the guarantee contained in
<PAGE>   61
                                                                              57


this Article VIII or acceptance of the guarantee contained in this Article VIII;
the Subsidiary Borrower Obligations, and any of them, shall conclusively be
deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon the guarantee contained in this Article
VIII; and all dealings between CBS or the Subsidiary Borrowers, on the one hand,
and the Administrative Agent and the Lenders, on the other, shall likewise be
conclusively presumed to have been had or consummated in reliance upon the
guarantee contained in this Article VIII. CBS waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon CBS
or any Subsidiary Borrower with respect to the Subsidiary Borrower Obligations.
The guarantee contained in this Article VIII shall be construed as a continuing,
absolute and unconditional guarantee of payment without regard to (a) the
validity or enforceability of this Agreement, any of the Subsidiary Borrower
Obligations or any collateral security therefor or guarantee or right of offset
with respect thereto at any time or from time to time held by the Administrative
Agent or any Lender, (b) the legality under applicable requirements of law of
repayment by the relevant Subsidiary Borrower of any Subsidiary Borrower
Obligations or the adoption of any requirement of law purporting to render any
Subsidiary Borrower Obligations null and void, (c) any defense, setoff or
counterclaim (other than a defense of payment or performance by the applicable
Subsidiary Borrower) which may at any time be available to or be asserted by CBS
against the Administrative Agent or any Lender, or (d) any other circumstance
whatsoever (with or without notice to or knowledge of CBS or any Subsidiary
Borrower) which constitutes, or might be construed to constitute, an equitable
or legal discharge of any Subsidiary Borrower for any Subsidiary Borrower
Obligations, or of CBS under the guarantee contained in this Article VIII, in
bankruptcy or in any other instance. When the Administrative Agent or any Lender
is pursuing its rights and remedies under this Article VIII against CBS, the
Administrative Agent or any Lender may, but shall be under no obligation to,
pursue such rights and remedies as it may have against any Subsidiary Borrower
or any other Person or against any collateral security or guarantee for the
Subsidiary Borrower Obligations or any right of offset with respect thereto, and
any failure by the Administrative Agent or any Lender to pursue such other
rights or remedies or to collect any payments from any Subsidiary Borrower or
any such other Person or to realize upon any such collateral security or
guarantee or to exercise any such right of offset, or any release of any
Subsidiary Borrower or any such other Person or of any such collateral security,
guarantee or right of offset, shall not relieve CBS of any liability under this
Article VIII, and shall not impair or affect the rights and remedies, whether
express, implied or available as a matter of law, of the Administrative Agent
and the Lenders against CBS.

         SECTION 8.5. Reinstatement. The guarantee contained in this Article
VIII shall continue to be effective, or be reinstated, as the case may be, if at
any time payment, or any part thereof, of any of the Subsidiary Borrower
Obligations is rescinded or must otherwise be restored or returned by the
Administrative Agent or any Lender upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of any Subsidiary Borrower or upon or as a result
of the appointment of a receiver, intervenor or conservator of, or trustee or
similar officer for, any Subsidiary Borrower or any substantial part of its
property, or otherwise, all as though such payments had not been made.

         SECTION 8.6. Payments. CBS hereby agrees that any payments in respect
of the Subsidiary Borrower Obligations pursuant to this Article VIII will be
paid to the Administrative Agent without setoff or counterclaim in Dollars at
the office of the Administrative Agent specified in Section 9.1.

assignment to a Lender or an affiliate of such Lender (other than if at the time
of such assignment, such Lender or affiliate would be entitled to require any
Borrower to pay greater amounts under Section 2.20(a) than if no such assignment

their prior written consent to such assignment (which consent shall not be
unreasonably withheld), (ii) (x) except in the case of assignments of
Competitive Loans or assignments to any Person that is a Lender prior to giving

amount of the aggregate Commitments and/or Loans retained by any assigning
Lender (determined as of the date the Assignment and Acceptance with respect to

execute and deliver to the Administrative Agent an Assignment and Acceptance,
together with a processing and recordation fee of $3,500 and (iv) the assignee,

of this Agreement or any other instrument or document furnished pursuant hereto
or the financial condition of CBS or any of its Subsidiaries or the performance
or observance by CBS or any of its Subsidiaries of any of its obligations under
this Agreement or any other instrument or document furnished pursuant hereto;
(iii) such assignee represents and warrants that it is legally authorized to
enter into such Assignment and Acceptance; (iv) such assignee confirms that it

such assigning Lender or any other Agent or Lender and based on such documents
<PAGE>   64
                                                                              60


and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agreement; (vi)
such assignee appoints and authorizes the Administrative Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement
as are delegated to the Administrative Agent by the terms hereof, together with
such powers as are reasonably incidental thereto; and (vii) such assignee agrees
that it will perform in accordance with their terms all the obligations which by
the terms of this Agreement are required to be performed by it as a Lender.

         (d) The Administrative Agent, acting for this purpose as agent of each
Borrower, shall maintain at one of its offices in The City of New York a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive in the absence of manifest error and each Borrower, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement. The Register shall be available for inspection
by any Borrower and any Lender at any reasonable time and from time to time upon
reasonable prior notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) above and, if required, the written consent of CBS and the Administrative
Agent to such assignment, the Administrative Agent shall (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to CBS.

         (f) Each Lender may without the consent of any Borrower or the Agents
sell participations to one or more banks, other financial institutions or other
entities (provided that any such other entity is a not a competitor of CBS or
any Affiliate of CBS) in all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitments and the Loans
owing to it); provided, however, that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(ii) the participating banks or other entities shall be entitled to the benefit
of the cost protection provisions contained in Sections 2.15, 2.16 and 2.20 to
the same extent as if they were Lenders (provided that additional amounts
payable to any Lender pursuant to Section 2.20 shall be determined as if such
Lender had not sold any such participations) and (iv) the Borrowers, the Agents
and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement, and such Lender shall retain the sole right to enforce the
obligations of each Borrower relating to the Loans and the Letters of Credit and
to approve any amendment, modification or waiver of any provision of this
Agreement (other than amendments, modifications or waivers decreasing any fees
payable hereunder or the amount of principal of or the rate at which interest is
payable on the Loans or LC Disbursements, extending any scheduled principal
payment date or date fixed for the payment of interest on the Loans or LC
Disbursements or of LC Fees or Commitment Fees, increasing the amount of or
extending the Commitments or releasing the guarantee contained in Article VIII,
in each case to the extent the relevant participant is directly affected
thereby).

         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.4, disclose to the assignee or participant or proposed assignee or participant
any information relating to any Borrower furnished to such Lender by or on
behalf of such Borrower; provided that, prior to any such disclosure of
information
<PAGE>   65
                                                                              61


designated by such Borrower as confidential, each such assignee or participant
or proposed assignee or participant shall execute a Confidentiality Agreement
whereby such assignee or participant shall agree (subject to the exceptions set
forth therein) to preserve the confidentiality of such confidential information.
A copy of each such Confidentiality Agreement executed by an assignee shall be
promptly furnished to CBS. It is understood that confidential information
relating to the Borrowers would not ordinarily be provided in connection with
assignments or participations of Competitive Loans.

         (h) Notwithstanding the limitations set forth in paragraph (b) above,
(i) any Lender may at any time assign or pledge all or any portion of its rights
under this Agreement to a Federal Reserve Bank and (ii) any Lender which is a
"fund" may at any time assign or pledge all or any portion of its rights under
this Agreement to secure such Lender's indebtedness, in each case without the
prior written consent of any Borrower or the Administrative Agent; provided that
each such assignment shall be made in accordance with applicable law and no such
assignment shall release a Lender from any of its obligations hereunder. In
order to facilitate any such assignment, each Borrower shall, at the request of
the assigning Lender, duly execute and deliver to the assigning Lender a
registered promissory note or notes evidencing the Loans made to such Borrower
by the assigning Lender hereunder.

         (i) Notwithstanding anything to the contrary contained herein, any Bank
(a "Granting Bank") may grant to a special purpose funding vehicle (a "SPC"),
identified as such in writing from time to time by the Granting Bank to the
Administrative Agent and the Borrower, the option to provide to the Borrower all
or any part of any Loan that such Granting Bank would otherwise be obligated to
make to the Borrower pursuant to this Agreement; provided that (i) nothing
herein shall constitute a commitment by any SPC to make any Loan, and (ii) if an
SPC elects not to exercise such option or otherwise fails to provide all or any
part of such Loan, the Granting Bank shall be obligated to make such Loan
pursuant to the terms hereof. The making of an Loan by an SPC hereunder shall
utilize the Commitment of the Granting Bank to the same extent, and as if, such
Loan were made by such Granting Bank. Each party hereto hereby agrees that no
SPC shall be liable for any indemnity or similar payment obligation under this
Agreement (all liability for which shall remain with the Granting Bank). In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that is
one year and one day after the payment in full of all outstanding commercial
paper or other senior indebtedness of any SPC, it will not institute against, or
join any other person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under the
laws of the United States or any State thereof. In addition, notwithstanding
anything to the contrary contained in this Section, any SPC may (i) with notice
to, but without the prior written consent of, the Borrower and the
Administrative Agent and without paying any processing fee therefor, assign all
or a portion of its interests in any Loans to the Granting Bank or to any
financial institutions (consented to by the Borrower and Administrative Agent )
providing liquidity and/or credit support to or for the account of such SPC to
support the funding or maintenance of Loans and (ii) disclose on a confidential
basis any non-public information relating to its Loans to any rating agency,
commercial paper dealer or provider of any surety, guarantee or credit or
liquidity enhancement to such SPC. This section may not be amended without the
written consent of any SPC which has been identified as such by the Granting
Bank to the Administrative Agent and the Borrower and which then holds any Loan
pursuant to this paragraph (i).

         (j) CBS shall not assign or delegate any of its rights or duties
hereunder without the prior consent of all the Lenders.

         SECTION 9.5. Expenses; Indemnity. (a) CBS agrees to pay all reasonable
out-of-pocket expenses incurred by the Agents in connection with the
preparation, negotiation, execution and delivery of this Agreement or in
connection with any amendments, modifications or waivers of the provisions
hereof (whether or not the transactions hereby contemplated shall be
consummated) or incurred by any Agent, any Lender or any Issuing Lender in
connection with the enforcement or protection of the rights of the Agents, the
Lenders or the Issuing Lenders under this Agreement or in connection with the
Loans made or the Letters of Credit issued hereunder, including, without
limitation, the reasonable fees, charges and disbursements of Simpson Thacher &
Bartlett, counsel for the Agents, and, in connection with any such enforcement
or protection, the reasonable fees, charges and disbursements of any other
counsel for any Agent, Lender or Issuing Lender.

         (b) CBS agrees to indemnify and hold harmless each Agent, each Lender,
each Issuing Lender and each of their respective directors, officers, employees,
affiliates and agents (each, an "Indemnified Person") against, and to reimburse
each Indemnified Person, upon its demand, for, any losses, claims, damages,
liabilities or other expenses ("Losses") to which such Indemnified Person
becomes subject insofar as such Losses arise out of or in any way relate to or
result from (i) the execution or delivery of this Agreement, any Letter of
Credit or any agreement or instrument contemplated hereby (and any amendment
hereto or thereto), the performance by the parties hereto or thereto of their
respective obligations hereunder or thereunder or the consummation of the
transactions contemplated hereby or thereby or (ii) the use (or proposed use) of
the proceeds of the Loans or other extensions of credit hereunder, including,
without limitation, Losses consisting of reasonable legal or other expenses
incurred in connection with investigating, defending or participating in any
legal proceeding relating to any of the foregoing (whether or not such
Indemnified Person is a party thereto); provided that the foregoing will not
apply to any Losses to the extent they are found by a final decision of a court
of competent jurisdiction to have resulted from the gross negligence or willful
misconduct of such Indemnified Person.

         (c) The provisions of this Section 9.5 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any investigation made by or on behalf of any
Agent or Lender. All amounts under this Section 9.5 shall be payable on written
demand therefor.

         SECTION 9.6. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Agent and each Lender is hereby authorized at
any time and from time to time, to the fullest extent permitted by law, to set
off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Agent or Lender to or for the credit or the account of any Borrower
against any of and all the obligations of such Borrower now or hereafter
existing under this Agreement or the Administrative Agent Fee Letter held by
such Agent or Lender which shall be due and payable. The rights of each Agent
and each Lender under this Section 9.6 are in addition to other rights and
remedies (including other rights of setoff) which such Agent or Lender may have.

         SECTION 9.7. APPLICABLE LAW. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
AGREEMENTS MADE WITHIN SUCH STATE, WITHOUT REGARD TO CONFLICTS OF LAW PROVISIONS
AND PRINCIPLES OF SUCH STATE.
<PAGE>   67
                                                                              63


         SECTION 9.8. Waivers; Amendment. (a) No failure or delay of any Agent,
any Issuing Lender or any Lender in exercising any power or right hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the exercise of any other right or power. The rights and remedies of the Agents,
the Issuing Lenders and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies which they would otherwise have. No waiver
of any provision of this Agreement or consent to any departure by any Borrower
from any such provision shall in any event be effective unless the same shall be
permitted by paragraph (b) below, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice or demand on any Borrower in any case shall entitle any Borrower to any
other or further notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement in writing entered into by
the Borrowers and the Required Lenders; provided, however, that no such
agreement shall (i) reduce the amount or extend the scheduled date of maturity
of any Loan or of any installment thereof, or reduce the stated amount of any LC
Disbursement, interest or fee payable hereunder or extend the scheduled date of
any payment thereof or increase the amount or extend the expiration date of any
Commitment of any Lender, in each case without the prior written consent of each
Lender directly affected thereby; (ii) amend, modify or waive any provision of
this Section 9.8(b), or reduce the percentage specified in the definition of
"Required Lenders", release the guarantee contained in Article VIII or consent
to the assignment or transfer by CBS of any of its rights and obligations under
this Agreement, in each case without the prior written consent of all the
Lenders; or (iii) amend, modify or waive any provision of Article VII without
the prior written consent of each Agent affected thereby; provided, further that
no such agreement shall amend, modify or otherwise affect the rights or duties
of the Administrative Agent, the Swingline Lenders or the Issuing Lenders
hereunder in such capacity without the prior written consent of the
Administrative Agent, each Swingline Lender directly affected thereby or each
Issuing Lender directly affected thereby, as the case may be.

         SECTION 9.9. Entire Agreement. This Agreement (together with the
Issuing Lender Agreements, the Subsidiary Borrower Designations and the
Subsidiary Borrower Requests) constitutes the entire contract between the
parties relative to the subject matter hereof. Any previous agreement among the
parties with respect to the subject matter hereof is superseded by this
Agreement. Nothing in this Agreement, expressed or implied, is intended to
confer upon any party other than the parties hereto any rights, remedies,
obligations or liabilities under or by reason of this Agreement.

         SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (a) CERTIFIES THAT
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (b) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10.

         SECTION 9.11. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or
<PAGE>   68

                                                                              64

unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

         SECTION 9.12. Counterparts. This Agreement may be executed in two or
more counterparts, each of which constitute an original but all of which when
taken together shall constitute but one contract, and shall become effective as
provided in Section 9.3.

         SECTION 9.13. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 9.14. Jurisdiction; Consent to Service of Process. (a) Each
Borrower hereby irrevocably and unconditionally submits, for itself and its
Property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement, or for recognition or enforcement of any judgment,
and each of the parties hereto hereby irrevocably and unconditionally agrees
that all claims in respect of any such action or proceeding may be heard and
determined in such New York State court or, to the extent permitted by law, in
such Federal court. Each of the parties hereto agrees that a final judgment in
any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Each Subsidiary Borrower designates and directs CBS at its offices at 51 West
52nd Street, New York, New York 10019, as its agent to receive service of any
and all process and documents on its behalf in any legal action or proceeding
referred to in this Section 9.14 in the State of New York and agrees that
service upon such agent shall constitute valid and effective service upon such
Subsidiary Borrower and that failure of CBS to give any notice of such service
to any Subsidiary Borrower shall not affect or impair in any way the validity of
such service or of any judgment rendered in any action or proceeding based
thereon. Nothing in this Agreement shall affect any right that any Agent or any
Lender may otherwise have to bring any action or proceeding relating to this
Agreement against any Borrower or its Properties in the courts of any
jurisdiction.

         (b) Each Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any New York State or Federal
court. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.1. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 9.15. Confidentiality. (a) Each Lender agrees to keep
confidential and not to disclose (and to cause its affiliates, officers,
directors, employees, agents and representatives to keep confidential and not to
disclose) and, at the request of CBS (except as provided below or if such Lender
is required to retain any Confidential Information (as defined below) pursuant
to customary internal or banking practices, bank regulations or applicable law),
promptly to return to CBS or destroy the Confidential Information and all copies
thereof, extracts therefrom and analyses or other materials based thereon,
except that such Lender shall be permitted to disclose Confidential Information
(i) to such of its officers, directors, employees, agents, affiliates and
representatives as need to know such Confidential Information in connection with
such Lender's participation in this Agreement, each of whom shall be informed by
such Lender of the confidential nature of the Confidential
<PAGE>   69
                                                                              65


Information and shall agree to be bound by the terms of this Section 9.15; (ii)
to the extent required by applicable laws and regulations or by any subpoena or
similar legal process or requested by any Governmental Authority or agency
having jurisdiction over such Lender; provided, however, that, except in the
case of disclosure to bank regulators or examiners in accordance with customary
banking practices, written notice of each instance in which Confidential
Information is required or requested to be disclosed shall be furnished to CBS
not less than 30 days prior to the expected date of such disclosure or, if 30
days' notice is not practicable under the circumstances, as promptly as
practicable under the circumstances; (iii) to the extent such Confidential
Information (A) is or becomes publicly available other than as a result of a
breach of this Agreement, (B) becomes available to such Lender on a
non-confidential basis from a source other than a party to this Agreement or any
other party known to such Lender to be bound by an agreement containing a
provision similar to this Section 9.15 or (C) was available to such Lender on a
non-confidential basis prior to this disclosure to such Lender by a party to
this Agreement or any other party known to such Lender to be bound by an
agreement containing a provision similar to this Section 9.15; (iv) as permitted
by Section 9.4(g); or (v) to the extent CBS shall have consented to such
disclosure in writing. As used in this Section 9.15, "Confidential Information"
shall mean any materials, documents or information furnished by or on behalf of
any Borrower in connection with this Agreement designated by or on behalf of
such Borrower as confidential.

         (b) Each Lender (i) agrees that, except to the extent the conditions
referred to in subclause (A), (B) or (C) of clause (iii) of paragraph (a) above
have been met and as provided in paragraph (c) below, (A) it will use the
Confidential Information only in connection with its participation in this
Agreement and (B) it will not use the Confidential Information in connection
with any other matter or in a manner prohibited by any law, including, without
limitation, the securities laws of the United States and (ii) understands that
breach of this Section 9.15 might seriously prejudice the interest of the
Borrowers and that the Borrowers are entitled to equitable relief, including an
injunction, in the event of such breach.

         (c) Notwithstanding anything to the contrary contained in this Section
9.15, each Agent and each Lender shall be entitled to retain all Confidential
Information for so long as it remains an Agent or a Lender to use solely for the
purposes of servicing the credit and protecting its rights hereunder.
