The number of Shares, Warrant Shares and Warrant Exercise Price have been
restated to give effect to a 1-for-2.5 reverse stock split described on page
F21 and F-22 of the Issuer's Prospectus dated November 1997.

In addition to the Agreement, the Issuer and Broadcasting entered into two (2)
related agreements, CBS/SportsLine Stockholder Agreement (Stockholder
Agreement) and the Co-Sale Agreement (Co-Sale Agreement). The Stockholder
Agreement provides, among other things, that the Issuer provide to Broadcasting
certain financial information and allow, under certain circumstances, for board
representation and/or observer rights. In addition, the Stockholder Agreement
provides that Broadcasting will in certain instances have the right of first
refusal to purchase new securities of the Issuer and will have demand
registration rights, piggyback registration rights and Form S-3 registration
rights. The Co-Sale Agreement provides Broadcasting with participation rights
in the event that Michael Levy, CEO of the Issuer, accepts any purchase offers
for shares of Common Stock owned by him. Any description of the Agreement, the
Stockholder Agreement and the Co-Sale Agreement contained herein are qualified
in their entirety by reference to the applicable agreements, which are attached
as Exhibits 1, 2, 3 and 4 respectively.

4(a), (b), (c), (e), (f), (g), (h), (i) and (j). Pursuant to the Agreement,
Broadcasting will acquire additional shares of Common Stock over the term of
the Agreement as set forth above and may acquire additional shares upon the
exercise of the warrants described above.

Broadcasting, CBS and Holding have no present plans or proposals with respect
to the disposition of any Common Stock or with respect to the matters set forth
in Items 4(b), (c), (e), (f), (g), (h), (i) and (j); but Broadcasting, CBS and
Holding do reserve their right to implement a different course of action at any
time in the future, depending upon such criteria as may be significant to
Broadcasting, CBS and Holding.

4(d) There are currently two (2) directors on the Issuer's Board of Directors
that were designated by Broadcasting pursuant to the Stockholders Agreement. As
long as it maintains a CBS Percentage (as defined in Section 1.4 on page 2 of
the Stockholder Agreement) of at least 10%, Broadcasting will have the right,
under the Stockholder Agreement, to designate a number of individuals equal to
the product of the total number of members of the Board of Directors of the
Issuer times the CBS Percentage. The Issuer will then use its best efforts,
including obtaining certain voting agreements, to cause the nomination and
election, from time to time, of Broadcasting's nominees. In the event that
Broadcasting is not entitled to so designate director nominees, it will be
entitled, under the Stockholder Agreement, to have a representative attend the
Issuer's Board of Directors meetings in a nonvoting, observer, capacity as long
as Broadcasting owns not

less than 250,000 shares of Common Stock. Broadcasting, CBS and Holding have no
current plans or proposals regarding representation on the Issuer's Board of
Directors other than as set forth above; but Broadcasting, CBS and Holding
reserve the right to implement a different course of action at any time in the
future depending upon their assessment of such criteria as may be significant
to Broadcasting, CBS and Holding.

5 (a) and(b) As of January 2, 1998, Broadcasting has voting and investment
power over 1,488,075 shares of Common Stock held by Broadcasting. Broadcasting
also has the right to acquire (i) 380,000 shares of Common Stock under a
warrant dated March 5, 1997 and amended December 30, 1997, which warrant is
exercisable in whole but not in part at any time up to and including January
21, 1998 (a copy of the warrant is attached as Exhibit 5 and a copy of the
extension is attached as Exhibit 6) and (ii) an additional 380,000 shares of
Common Stock under a warrant dated January 2, 1998, which warrant is presently
exercisable in whole or part at any time prior to December 31, 1998. CBS and
Holding may be deemed to beneficially own all the Common Stock beneficially
owned by Broadcasting.

In the aggregate, Broadcasting, CBS and Holding share voting and investment
power over 2,248,075 shares of Common Stock (includes 760,000 shares covered by
the two outstanding warrants) or 14.8% of the Common Stock of Issuer as of
January 2, 1998 (assuming the exercise of both warrants and assuming 15,128,325
shares of Common Stock outstanding for purposes of this calculation, based on
information from the Issuer that there were outstanding shares of 13,632,523
after Issuer's public offering in November 1997; plus the 735,802 issued to
Broadcasting on January 2, 1998, plus the two warrants held by Broadcasting for
760,000 shares).

5 (c) Broadcasting received, pursuant to the Agreement, 735,802 shares of
Common Stock and a warrant for 380,000 shares of Common Stock on January 2,
1998.

On December 30, 1997, Issuer and Broadcasting entered into an amendment to the
warrant dated March 5, 1997. The amendment provided for this warrant to be
exercisable in whole but not in part at any time up to and including January
21, 1998.

Except as described above, neither CBS, Broadcasting, Holding nor, to their
knowledge, any person named in Schedules 1-A, 1-B or 1-C beneficially owns any
shares of Common Stock or has effected any transactions in the Common Stock
during the past 60 days.

5(d)          None.

5(e)          Not applicable.

Securities, the Ad Securities, the Warrants and the shares of Common Stock

being acquired from SportsLine USA, Inc. in a transaction not involving a
public offering; and that under such laws and applicable regulations, such
Securities may be resold without registration under the Securities Act only in
certain limited circumstances. CBS agrees that the Securities are being and
will be acquired for investment for CBS's own account, and not with a view to
the resale or distribution thereof, and that CBS has no present intention of
selling, granting any participation in, or otherwise distributing the
Securities. CBS further agrees not to make any disposition of all or any
portion of the Securities unless (i) there is then in effect a registration
statement under the Securities Act of 1933 covering such proposed disposition
and such disposition is made in accordance with such registration statement, or
(ii) CBS shall have furnished SportsLine USA, Inc. with an opinion of counsel,
reasonably satisfactory to SportsLine USA, Inc., that such disposition will not
require registration under the Securities Act. Each certificate representing
the Securities shall be stamped or otherwise imprinted with a legend
substantially in the following form:

         1933 (THE "SECURITIES ACT") OR UNDER APPLICABLE STATE SECURITIES LAWS

         REGISTRATION, PROVIDED THAT THE SELLER DELIVERS TO THE COMPANY AN
         OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY CONFIRMING
         THE AVAILABILITY OF SUCH EXEMPTION.

In addition to the foregoing, during each Contract Year, the Content Shares and
Ad Shares issued to CBS on the first day of such Contract Year shall not, until
the first business day of the subsequent Contract Year, be transferred, sold or
otherwise disposed of by CBS, except as may be permitted by Paragraph 20.1
hereof. To enforce the foregoing covenant, SportsLine USA, Inc. shall have
right to place the following restrictive legend on the certificates
representing the


                                      -19-

              b)   The odds section of the CBS SportsLine Site shall not
                   display the word "odds" in its main headings or otherwise in

              e)   The CBS SportsLine Site shall not include advertising from
                   casinos, sports books or other gambling enterprises, nor

THESE WARRANTS AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THESE
WARRANTS (THE "WARRANT SHARES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933 (THE "SECURITIES ACT") OR UNDER APPLICABLE STATE SECURITIES LAWS.
THE WARRANT SHARES MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS
REGISTERED UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR
PURSUANT TO AVAILABLE EXEMPTIONS FROM SUCH REGISTRATION, PROVIDED THAT THE
SELLER DELIVERS TO THE COMPANY AN OPINION OF COUNSEL SATISFACTORY TO THE
COMPANY CONFIRMING THE AVAILABILITY OF SUCH EXEMPTION. INVESTORS SHOULD BE
AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS
INVESTMENT FOR AN INDEFINITE PERIOD OF TIME.

[INSERT DATE BEGINNING OF CONTRACT YEAR]

                              SPORTSLINE USA, INC.

              Warrants for the Purchase of Shares of Common Stock


         FOR VALUE RECEIVED, SPORTSLINE USA, INC., a Delaware corporation
("SportsLine" or the "Company"), hereby certifies that CBS INC (the "Holder")
is entitled, subject to the provisions contained herein, to purchase from the
Company 000,000 fully paid and non-assessable shares of Common Stock (as
defined below), subject to adjustment as provided herein, at an exercise price
per share of Common Stock (the "Exercise Price") of $[INSERT EXERCISE PRICE].

         The term "Common Stock" means the Common Stock, par value $.01 per
share, of the Company as constituted on the date hereof. The number of shares
of Common Stock to be received upon the exercise of these Warrants may be
adjusted from time to time as hereinafter set forth. The shares of Common Stock
deliverable upon such exercise, and as adjusted from time to time, are
hereinafter referred to as "Warrant Stock." The term "Other Securities" means
any other securities that may be issued by the Company in addition to, or in
substitution for, the Warrant Stock.

         References herein to the "Company" are to (i) SportsLine and any
successor thereto, (ii) any successor corporation resulting from the merger or
consolidation of SportsLine, or any successor thereto, with another corporation
or (ii) any corporation to which SportsLine, or any successor thereto, has
transferred its property or assets as an entirety or substantially as an
entirety.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of these Warrants, and (in the
case of loss, theft or destruction) of reasonably satisfactory indemnification,
and upon surrender and cancellation of these Warrants, if mutilated, the
Company shall execute and deliver new Warrants of like tenor and date. Any such
new Warrants, upon execution and delivery, shall constitute an additional
contractual obligation on the part of the Company, whether or not these
Warrants so lost, stolen, destroyed or mutilated shall be at any time
enforceable by anyone.

         The Holder agrees with the Company that these Warrants are issued ,
and all the rights hereunder shall be held subject to, all of the conditions,
limitations and provisions set forth herein, including the following:

         1. Exercise of Warrants. The Warrants may be exercised, in whole or in
part, at any time prior to December 31, ____ [END OF CONTRACT YEAR]; provided,
however, that the exercisability of the Warrants shall be subject to the
condition that the Agreement dated as of March 5, 1997 between


<PAGE>   51

SportsLine and the Holder (the "Principal Agreement"), as amended or modified,
shall be in effect, and no further Warrants shall be exercisable on or after
the expiration, nonrenewal or termination of said agreement. Subject to the
foregoing, the Warrants shall be exercisable by presentation and surrender of
these Warrants to the Company at its principal office (which on the date hereof
is 6340 N.W. 5th Way, Fort Lauderdale, Florida 33309), or at the office of its
stock transfer agent (which on the date hereof is the Company), if any, with
the Warrant Exercise Form attached hereto duly executed and accompanied by
payment (either in cash or by certified or official bank check or checks,
payable to the order of the Company) of the Exercise Price for the number of
shares specified in such form. Upon receipt by the Company of the Warrants,
together with the Exercise Price, at its office, or by the Company's stock
transfer agent at its office, in proper form for exercise, the Holder shall be
deemed to be the holder of record of the Warrant Stock (and Other Securities)
issuable upon such exercise, notwithstanding that the transfer books of the
Company shall then be closed or that certificates representing such Warrant
Stock (or Other Securities) shall not then be actually delivered to the Holder.
The Company shall pay any and all documentary stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of Warrant Stock
(and Other Securities) upon exercise of these Warrants.

         2. Reservation of Shares and Other Securities. The Company will at all
times reserve for issuance and delivery upon exercise of these Warrants all
shares of Warrant Stock and other shares of capital stock of the Company (and
Other Securities) from time to time receivable upon exercise of these Warrants.
All such shares (and Other Securities) shall be duly authorized and, when issued
upon such exercise, shall be validly issued, fully paid and non-assessable and
free and clear of all preemptive rights.

         3. Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issuable upon the exercise of these Warrants, but
the Company shall pay the Holder an amount equal to the fair market value of
such fractional share in lieu of each fraction of a share otherwise issuable
upon any exercise of these Warrants, as determined by the Board of Directors in
its reasonable discretion.

         4. Exchange of Warrants. These Warrants are exchangeable, without
expense, at the option of the Holder, upon presentation and surrender hereof to
the Company or at the office of its stock transfer agent, if any, for other
Warrants of different denominations, entitling the Holder to purchase in the
aggregate the same number of shares of Warrant Stock (and Other Securities)
purchasable hereunder.

         5. Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights as a shareholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed herein.

         6. Anti-Dilution Provisions.

         6.1 Adjustment for Recapitalization. If the Company shall at any time
subdivide its outstanding shares of Common Stock (or Other Securities at the
time receivable upon the exercise of these Warrants) by recapitalization,
reclassification or split-up thereof, or if the Company shall declare a stock
dividend or distribute shares of Common Stock to its shareholders, the number
of shares of Common Stock (or Other Securities) subject to these Warrants
immediately prior to such subdivision shall be proportionately increased and
the Exercise Price per share shall be proportionately decreased, and if the
Company shall at any time combine the outstanding shares of Common Stock (or
Other Securities) by recapitalization, reclassification or combination
thereof, the number of shares of Common Stock (or Other Securities) subject to
these Warrants immediately prior to such combination shall be proportionately
decreased and the Exercise Price per share shall be proportionately increased.
Any such adjustments pursuant to this Section 6.1 shall be effective at the
close of business on the effective date of such subdivision or combination or,
if any adjustment is the result of a stock dividend or distribution, then the
effective date for such adjustment shall be the record date therefor.



                                      -2-
<PAGE>   52

         6.2 Adjustment for Reorganization Consolidation Merger Etc. (a) In
case of any reorganization of the Company (or any other corporation, the
securities of which are at the time receivable upon the exercise of these
Warrants) after the date hereof or in case after such date the Company (or any
such other corporation) shall consolidate with or merge into another
corporation or convey all or substantially all of its assets to another
corporation, then, and in each such case, the Holder, upon the exercise hereof,
at any time after the consummation of such reorganization, consolidation,
merger or conveyance, shall be entitled to receive, in lieu of the securities
and property receivable upon the exercise of these Warrants prior to such
consummation, the securities or property to which the Holder would have been
entitled upon such consummation if the Holder had exercised these Warrants
immediately prior thereto (but had not exercised any rights with respect to
such securities or property in connection with the reorganization,
consolidation, merger or conveyance); in each such case, the terms of these
Warrants shall be applicable to the securities or property receivable upon the
exercise of these Warrants after such consummation.

         (b) In any case where the Company shall consolidate with or merge into
another corporation, and shall not be the surviving corporation, or shall
convey all or substantially all of its assets to another corporation, then, and
in each such case, the Company shall, as a condition of the closing of such
transaction, require that the surviving corporation or the corporation that
shall have received substantially all of the Company's assets expressly assume
the obligations of the Company under these Warrants in a form reasonably
satisfactory to the Holder.

         6.3 No Impairment. The Company will not, by amendment of its charter
or through reorganization, consolidation, merger, dissolution, issue or sale
of securities, sale of assets or any other voluntary action, willfully avoid or
seek to avoid the observance or performance of any of the terms of these
Warrants, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Holder against impairment.
Without limiting the generality of the foregoing, while these Warrants are
outstanding, the Company (a) will not permit the par value, if any, of the
shares of Warrant Stock to be above the amount payable therefor upon such
exercise and (b) will take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue or sell fully paid and
non-assessable shares of Warrant Stock and Other Securities upon the exercise
of these Warrants.

         6.4 Certificate as to Adjustments. In each case of an adjustment in
the number of shares of Warrant Stock or Other Securities receivable upon the
exercise of these Warrants, the Company at its expense will promptly compute
such adjustment in accordance with the terms of these Warrants and prepare a
certificate executed by an executive officer of the Company setting forth such
adjustment and showing in detail the facts upon which such adjustment is based.
The Company will forthwith mail a copy of each such certificate to the Holder.

         6.5 Notices of Record Date, Etc. In case:

         (a) the Company shall take a record of the holders of its Common
Stock (or Other Securities at the time receivable upon the exercise of these
Warrants) for the purpose of entitling them to receive any dividend (other than
a cash dividend at the same rate as the rate of the last cash dividend
theretofore paid) or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities, or to receive any other right; or

         (b) of any capital reorganization of the Company, any reclassification
of the capital stock of the Company, any consolidation or merger of the Company
with or into another corporation, or any conveyance of all or substantially all
of the assets of the Company to another corporation; or

         (c) of any voluntary or involuntary dissolution, liquidation or
winding up of the Company;


                                      -3-
<PAGE>   53

then, and in each such case, the Company shall mail or cause to be mailed to
the Holder a notice specifying, as the case may be, (i) the date on which a
record is to be taken for the purpose of such dividend, distribution or right,
and stating the amount and character of such dividend, distribution or right,
or (ii) the date on which such reorganization, reclassification, consolidation,
merger, conveyance, dissolution, liquidation or winding up is to take place,
and the time, if any, to be fixed, as to which the holders of record of Warrant
Stock (or such other securities at the time receivable upon the exercise of
these Warrants) shall be entitled to exchange their shares of Warrant Stock
(or such other securities) for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding up. Such notice shall be mailed at least
20 days prior to the date therein specified and these Warrants may be exercised
prior to said date during the term of these Warrants.

         8. Restrictions on Transfer of Warrants, Warrant Stock and Other
Securities. The Warrant Stock and Other Securities may not be sold, transferred
or otherwise disposed of unless registered under the Securities Act of 1933
(the "Securities Act") and any applicable state securities laws or pursuant to
available exemptions from such registration, provided that the seller delivers
to the Company an opinion of counsel satisfactory to the Company confirming the
availability of such exemption.

         9. Legend. Unless the shares of Warrant Stock or Other Securities have
been registered under the Securities Act, upon exercise of any of these
Warrants and the issuance of any of the shares of Warrant Stock or Other
Securities, all certificates representing such securities shall bear on the
face thereof substantially the following legend:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933 (THE "SECURITIES ACT") OR UNDER APPLICABLE STATE SECURITIES LAWS
         AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS
         REGISTERED UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE
         SECURITIES LAWS OR PURSUANT TO AVAILABLE EXEMPTIONS FROM SUCH
         REGISTRATION, PROVIDED THAT THE SELLER DELIVERS TO THE COMPANY AN
         OPINION OF COUNSEL SATISFACTORY TO THE COMPANY CONFIRMING THE
         AVAILABILITY OF SUCH EXEMPTION.

         10. No Rights or Liabilities as Shareholder. This Warrant does not by
itself entitle the Holder to any voting rights or other rights as a
shareholder of the Company. In the absence of affirmative action by the Holder
to purchase Warrant Stock by exercise of this Warrant, no provisions of this
Warrant, and no enumeration herein of the rights or privileges of the Holder
shall cause the Holder to be a stockholder of the Company for any purpose.

         11. Amendment; Waiver. Any term of the Warrants may be amended and the
observance of any term of the Warrants may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holder. Any amendment or waiver effected
in accordance with this Section shall be binding upon the Holder and the
Company.

         12. Notices. All notices required hereunder shall be in writing and
shall be deemed given when telegraphed, delivered personally or within two days
after mailing when mailed by certified or registered mail, return receipt
requested, to the Company at its principal office, or to the Holder at the
address set forth on the record books of the Company, or at such other address
of which the Company or the Holder has been advised by notice in writing
hereunder.

                      CBS/SPORTSLINE STOCKHOLDER AGREEMENT

         This CBS/SPORTSLINE STOCKHOLDER AGREEMENT (this "Agreement") is made
and entered into as of March 5, 1997, between SportsLine USA, Inc., a Delaware
corporation (the "Company"), and CBS INC., a New York corporation ("CBS").

                                R E C I T A L S

         A. CBS and the Company have entered into that certain Agreement, dated
as of the date hereof (the "Principal Agreement;" capitalized terms used
herein and not otherwise defined shall have the meanings defined in the
Principal Agreement), pursuant to which, among other things, CBS will acquire
shares of Common Stock and Warrants in consideration of the license by CBS of
the CBS Logos and the CBS Content and provision by CBS of certain broadcast
advertising and promotion.

         B. CBS and the Company have agreed that the terms and conditions of
this Agreement shall govern CBS's rights with respect to the shares of Common
Stock it acquires pursuant to the Principal Agreement or upon the exercise of
the Warrants.

         NOW THEREFORE, in consideration of the above recitals and the mutual
covenants made herein, the parties hereby agree as follows:

1.       INFORMATION AND DIRECTOR RIGHTS.

         1.1 Financial and Other Information. The Company covenants and
agrees that, so long as the CBS Percentage (as defined in Section 1.3 hereof)
is at least ten percent (10%), the Company will furnish to CBS such financial
and other information (including annual, quarterly and monthly reports and an
annual budget) as the Company may from time to time be required to furnish to
the holders of the Company's outstanding Series A, Series B or Series C
preferred stock (the "Preferred Stock Holders") pursuant to the Amended and
Restated Investors' Rights Agreement dated as of September 25, 1996, among the
Company, the holders of the Preferred Stock, The Estate of Burk Zanft and
Michael Levy, as now in effect and as hereinafter amended from time to time in
accordance with the terms thereof (the "Investors' Rights Agreement"). Such
financial and other information shall be provided to CBS by the Company at such
time or times and in the same manner as it is provided to the Preferred Stock
Holders in accordance with the Investors' Rights Agreement. CBS agrees to hold
all such financial and other information received pursuant to this Section 1.1
in confidence, and not to use or disclose any of such information to any third
party (other than to any regulatory authority to which CBS is subject
requesting the same), except to the extent such information may be made
publicly available by the Company.

         1.2 CBS Designees. So long as the CBS Percentage is at least ten
percent (10%), CBS shall have the right to elect (and maintain in office) as
members of the Company's Board of Directors (the "Board") a number of
individuals equal to the product of (i) total number of members of the Board,
times (ii) the CBS Percentage (the "CBS Designees"). The CBS Designees shall
be designated from time to time in writing by CBS. Upon execution of this
Agreement, the Company shall cause two (2) CBS Designees to be appointed to the
Board. The Company further agrees to use its best efforts to cause the
nomination and election from time to time of the CBS Designees, including
obtaining the agreement of the holders of a majority of its outstanding Common
Stock and preferred stock to vote their shares of the Company's capital stock
to cause the election to the Board of any CBS Designees designated for election
to the Board by CBS.

         1.3 Observer Rights. If CBS is no longer entitled to appoint CBS
Designees in accordance with Section 1.2, then so long as CBS owns not less
than 250,000 shares of Common Stock, CBS, at its own expense, shall be entitled
to have a representative attend all meetings of the Company's Board of
Directors in a nonvoting observer capacity (each, a "CBS Representative"). If
CBS designates a CBS Representative to the Company, the Company shall
concurrently provide the CBS Representative with



<PAGE>   59

copies of all notices, minutes, consents and other materials it provides to
members of the Board of Directors; provided, that the CBS Representative shall
agree to hold in confidence and trust and to act in a fiduciary manner with
respect to all information so provided; and provided further, that the Company
reserves the right to withhold any information and to exclude any CBS
Representative from any meeting or portion thereof if access to such
information or meeting or attendance at such meeting could adversely affect
the attorney-client privilege between the Company and its counsel or would
result in disclosure of trade secrets to any CBS Representative.

         1.4 CBS Percentage. For purposes of this Agreement, the term "CBS
Percentage" shall mean, at any particular time, that percentage determined by
dividing (a) the sum of (i) the number of shares of Common Stock CBS then
holds, plus (ii) the number of shares of Common Stock which CBS thereafter
has the right to acquire under the Principal Agreement or upon exercise of any
Warrants outstanding or to be granted thereunder, by (b) the sum of (i) the
total number of shares of Common Stock of the Company then outstanding plus
(ii) the total number of shares of Common Stock of the Company into which all
then outstanding shares of preferred stock of the Company are then convertible
plus (iii) the number of shares of Common Stock of the Company reserved for
issuance under stock purchase and stock option plans of the Company and
outstanding options and warrants.

2.       RIGHT OF FIRST REFUSAL.

         2.1 General. CBS shall have the right of first refusal to purchase
the CBS Percentage of all (or any part) of any New Securities that the Company
may from time to time issue after the date of this Agreement.

         2.2 New Securities. "New Securities" shall mean any Common Stock or
preferred stock of the Company, whether now authorized or not, and rights,
options or warrants to purchase such Common Stock or preferred stock, and
securities of any type whatsoever that are, or may become, convertible or
exchangeable into such Common Stock or preferred stock; provided, however, that
the term "New Securities" does not include: (i) shares of the Company's
Common Stock (and/or options or warrants therefor) issued to employees,
officers, directors, contractors, advisors or consultants of the Company
pursuant to incentive agreements or plans unanimously approved by the Board of
Directors of the Company ("Employee Options"); (ii) any securities issuable
upon conversion of or with respect to any then outstanding shares of the
Company's Series A, Series B or Series C preferred stock or Common Stock or
other securities issuable upon conversion thereof; (iii) any securities
issuable upon exercise of any of the options, warrants or rights (other than
Employee Options)("Warrant Securities") outstanding as of the date hereof, any
Warrant Securities hereafter unanimously approved by the Board of Directors
of the Company, and any Common Stock or other securities issuable upon the
conversion of any Warrant Securities; (iv) shares of the Company's Common Stock
or preferred stock issued in connection with any stock split or stock dividend;
(v) securities offered by the Company to the public pursuant to a registration
statement filed under the Securities Act; (vi) up to 50,000 shares of the
Company's Common Stock (and/or options or warrants therefor) issued or issuable
to nonaffiliate third parties providing the Company with equipment leases, real
property leases, loans, credit lines, guaranties of indebtedness, cash price
reductions or similar financing, provided that this exception (vi) shall not
apply unless the arrangement is unanimously approved by the Company's Board of
Directors; or (vii) securities issued pursuant to the acquisition of another
corporation or entity by the Company by consolidation, merger, purchase of all
or substantially all of the assets, or other reorganization in which the
Company acquires, in a single transaction or series of related transactions,
all or substantially all of the assets of such other corporation or entity or
fifty percent (50%) or more of the voting power of such other corporation or
entity or fifty percent (50%) or more of the equity ownership of such other
entity.

         2.3 Procedures. In the event that the Company proposes to undertake an
issuance of New Securities, it shall give CBS written notice of its intention
to issue New Securities (the "Notice"),


                                       2
<PAGE>   60

describing the type of New Securities and the price and the general terms upon
which the Company proposes to issue such New Securities. CBS shall have fifteen
(15) days from the date of mailing of any such Notice to agree in writing to
purchase the CBS Percentage of such New Securities for the price and upon the
general terms specified in the Notice by giving written notice to the Company
and stating therein the quantity of New Securities to be purchased (not to
exceed the CBS Percentage).

         2.4 Failure to Exercise. In the event that CBS fails to exercise the
right of first refusal within such fifteen (15) day period, then the Company
shall have 120 days thereafter to sell the New Securities with respect to which
CBS's rights of first refusal hereunder were not exercised, at a price and upon
general terms not materially more favorable to the purchasers thereof than
specified in the Notice. In the event that the Company has not issued and sold
the New Securities within such 120 day period, then the Company shall not
thereafter issue or sell any New Securities without again first offering such
New Securities to CBS pursuant to this Section 2.

3.       REGISTRATION RIGHTS.

         3.1 Definitions. For purposes of this Section 3:

              (a) Registration. The terms "register," "registered," and
"registration" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act of 1933, as
amended (the "Securities Act"), and the declaration or ordering of
effectiveness of such registration statement.

              (b) Registrable Securities. The term "Registrable Securities"
means: all shares of Common Stock (i) issued by the Company to CBS as Content
Shares or Ad Shares pursuant to the Principal Agreement, (ii) issuable upon the
exercise of outstanding and exercisable Warrants granted pursuant to the
Principal Agreement, and (iii) any shares of Common Stock of the Company issued
as (or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to,
or in exchange for or in replacement of, all such shares of Common Stock
described in clause (i) or (ii) of this Section 3.1(b); excluding in all cases,
however, any Registrable Securities sold by CBS in a transaction in which
rights under this Section 3 are not assigned in accordance with this Agreement
or any Registrable Securities sold to the public or sold pursuant to Rule 144
promulgated under the Securities Act.

              (c) Registrable Securities Then Outstanding. The number of shares
of "Registrable Securities then outstanding" shall mean the number of shares of
Common Stock which are Registrable Securities and (1) are then issued and
outstanding or (2) are then issuable pursuant to the exercise or conversion of
then outstanding and then exercisable options, warrants or convertible
securities.

              (d) Form S-3. The term "Form S-3" means such form under the
Securities Act as is in effect on the date hereof or any successor registration
form under the Securities Act subsequently adopted by the SEC which permits
inclusion or incorporation of substantial information by reference to other
documents filed by the Company with the SEC.

              (e) SEC. The term "SEC" or "Commission" means the United States,
Securities and Exchange Commission.

         3.2 Demand Registration. If the Company shall receive at any time six
months or more after the effective date of the Company's initial public
offering of its securities pursuant to a registration filed under the
Securities Act a written request from CBS that the Company file a registration
statement under the Securities Act covering the registration of Registrable
Securities pursuant to this Section 3.2, then the Company shall effect, as soon
as practicable and in any event within sixty (60) days of the

                                       3
<PAGE>   61

receipt of such request, the registration under the Securities Act of all
Registrable Securities which CBS requests to be registered and included in
such registration by such written notice, subject only to the limitations of
this Section 3.2; provided that the Registrable Securities requested by CBS to
be registered pursuant to such request must have an anticipated aggregate
public offering price (before any underwriting discounts and commissions) of
not less than $5,000,000.

         If CBS intends to distribute the Registrable Securities covered by its
request by means of an underwriting, then CBS shall so advise the Company as a
part of its request made pursuant to this Section 3.2. The underwriter shall be
selected by the Company with the consent of CBS, which consent will not
unreasonably be withheld, and CBS shall enter into an underwriting agreement in
customary form with the managing underwriter or underwriters selected for such
underwriting by the Company. Notwithstanding any other provision of this
Section 3.2, if the underwriter(s) advise(s) the Company in writing that
marketing factors require a limitation of the number of securities to be
underwritten then the Company shall so advise CBS, and the number of
Registrable Securities that may be included in the underwriting shall be
reduced as required by the underwriter(s) and allocated first, to the Company,
second, to the Preferred Stock Holders, if and to the extent such Preferred
Stock Holders have exercised their registration rights granted under the
Investors' Rights Agreement, and third, if and only to the extent that the
inclusion of such Registrable Securities will not reduce the amount of the
shares that the Preferred Stock Holders may include in such registration and
underwriting, to CBS; provided, however, that the managing underwriter(s) shall
have the absolute right and discretion to exclude from a registration and
underwriting relating to the Company's initial public offering any and all of
the Registrable Securities. Any Registrable Securities excluded and withdrawn
from such underwriting shall be withdrawn from the registration.

         The Company is obligated to effect only one (1) registration pursuant
to this Section 3.2. The Company shall not be deemed to have effected a
registration pursuant to this Section 3.2 unless a registration statement in
respect thereof shall have been declared effective by the Commission.

         Notwithstanding the foregoing, if the Company shall furnish to CBS a
certificate signed by the President or Chief Executive Officer of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such registration statement to be filed and it is therefore essential to
defer the filing of such registration statement, then the Company shall have
the right to defer such filing for a period of not more than 120 days after
receipt of the request of CBS; provided, however, that the Company may not
utilize this right more than once in any twelve (12) month period.

         3.3 Piggyback Registrations. The Company shall notify CBS in writing
at least thirty (30) days prior to filing any registration statement under the
Securities Act for purposes of effecting a public offering of securities of the
Company (including registration statements relating to secondary offerings of
securities of the Company but excluding registration statements relating to
offerings of securities pursuant to any employee benefit plan or a corporate
reorganization) and will afford CBS an opportunity to include in such
registration statement all or any part of the Registrable Securities then held
by CBS. If CBS desires to include in any such registration statement all or any
part of the Registrable Securities then held by it, CBS shall, within twenty
(20) days after receipt of the above-described notice from the Company, so
notify the Company in writing, and in such notice shall inform the Company of
the number of Registrable Securities CBS wishes to include in such registration
statement. If CBS decides not to include all of its Registrable Securities in
any registration statement thereafter filed by the Company, CBS shall
nevertheless continue to have the right to include any Registrable Securities
in any subsequent registration statement or registration statements as may be
filed by the Company with respect to offerings of its securities, all upon the
terms and conditions set forth herein.




                                       4
<PAGE>   62

         If a registration statement under which the Company gives notice under
this Section 3.3 is for an underwritten offering, then the Company shall so
advise CBS. In such event, the right of CBS to have any of its Registrable
Securities included in a registration pursuant to this Section 3.3 shall be
conditioned upon CBS's participation in such underwriting and the inclusion of
CBS's Registrable Securities in the underwriting to the extent provided herein.
CBS and any other stockholders proposing to distribute their Company securities
through such underwriting shall enter into an underwriting agreement in
customary form with the managing underwriter or underwriter(s) selected for
such underwriting. Notwithstanding any other provision of this Agreement, if
the managing underwriter determine(s) in good faith that marketing factors
require a limitation of the number of shares to be underwritten, then the
managing underwriter(s) may exclude shares (including Registrable Securities)
from the registration and the underwriting, and the number of shares that may
be included in the registration and the underwriting shall be allocated, first,
to the Company, second, to the Preferred Stock Holders, if and to the extent
such Preferred Stock Holders have exercised their registration rights granted
under the Investors' Rights Agreement, and third if and only to the extent that
the inclusion of such Registrable Securities will not reduce the amount of the
shares that the Preferred Stock Holders may include in such registration and
underwriting, to CBS; provided, however, that the managing underwriter(s) shall
have the absolute right and discretion to exclude from a registration and
underwriting relating to the Company's initial public offering any and all of
the Registrable Securities. If CBS disapproves of the terms of any such
underwriting, CBS may elect to withdraw therefrom by written notice to the
Company and the underwriter(s), delivered at least ten (10) business days prior
to the effective date of the registration statement. Any Registrable Securities
excluded or withdrawn from such underwriting shall be excluded and withdrawn
from the registration.

         3.4 Form S-3 Registration. In case the Company shall receive from CBS
a written request or requests that the Company effect a registration on Form
S-3 and any related qualification or compliance with respect to all or a part
of the Registrable Securities then owned by CBS, then the Company will, as soon
as practicable after receipt of the request, file a Form S-3 registration
statement covering such Registrable Securities and effect such registration and
all such qualifications and compliances as may be so requested and as would
permit or facilitate the sale and distribution of such Registrable Securities,
together with the securities of any holders of securities of the Company (other
than CBS) entitled to inclusion in such registration; provided, however, that
the Company shall not be obligated to effect any such registration,
qualification or compliance pursuant to this Section 3.4:

                  (i) if the Company is not then eligible for the use of Form
S-3, or if Form S-3 is not available for such offering by CBS;

                  (ii) if CBS, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose
to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public of less than $1,000,000;

                  (iii) if the Company shall furnish to CBS a certificate
signed by the President or Chief Executive Officer of the Company stating that
in the good faith judgment of the Board of Directors of the Company, it would
be seriously detrimental to the Company and its stockholders for such Form S-3
Registration to be effected at such time, in which event the Company shall have
the right to defer the filing of the Form S-3 registration statement no more
than once during any twelve month period for a period of not more than 120 days
after receipt of the request of CBS under this Section 3.4;

                  (iv) if the Company has, within the twelve (12) month period
preceding the date of such request, already effected two (2) registrations on
Form S-3 for CBS or other holders of its securities; or




                                       5
<PAGE>   63

                  (v) in any particular jurisdiction in which the Company would
be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance.

         A Form S-3 registration effected pursuant to this Section 3.4 shall
not be deemed to be demand registration as described in Section 3.3 above.

         3.5 Obligations of the Company. Whenever required to effect the
registration of any Registrable Securities under this Agreement, the Company
shall, as expeditiously as reasonably possible:

              (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of CBS, keep
such registration statement effective for up to one hundred twenty (120) days
or until the distribution contemplated in the Registration Statement has been
completed. whichever is earlier; provided, however, that such one hundred
twenty day (120) shall be extended for a period of time equal to the period CBS
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company.

              (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

              (c) Furnish to CBS such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act. and such other documents as they may reasonably request in
order to facilitate the disposition of the Registrable Securities owned by CBS
that are included in such registration.

              (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by CBS, provided
that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdictions.

              (e) In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter(s) of such offering. CBS and any
other holders of securities of the Company included in such registration and
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

              (f) Notify CBS at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement. as
then in effect. includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

              (g) Furnish, at the request of CBS. on the date that such
Registrable Securities are delivered to the underwriters for sale. if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the registration statement
with respect to such securities becomes effective, (i) an opinion, dated as of
such date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering and reasonably satisfactory to CBS, addressed
to the



                                       6
<PAGE>   64

underwriters, if any, and CBS and any other stockholders requesting
registration of securities in such registration, and (ii) a "comfort" letter
dated as of such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering and
reasonably satisfactory to CBS and any other stockholders requesting
registration of securities in such registration, addressed to the underwriters,
if any, and to CBS and such other stockholders.

              (h) Cause the Registrable Securities registered pursuant hereto
to be listed on each securities exchange or market on which similar securities
issued by the Company are then listed.

              (i) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

         3.6 Expenses. All expenses incurred by the Company in connection with
a registration pursuant to Section 3.2, 3.3 or 3.4 (excluding underwriters' and
brokers' discounts and commissions), including. without limitation all federal
and "blue sky" registration and qualification fees, printing expenses, fees and
disbursements of the Company's accountants and counsel, and reasonable fees and
disbursements of one counsel for CBS and all other selling stockholders, shall
be borne by the Company. CBS and each other stockholder participating in a
registration pursuant to Section 3.2, 3.3 or 3:4 shall bear their proportionate
share (based on the total number of shares sold in such registration other than
for the account of the Company) of all discounts and commissions payable to
underwriters or brokers in connection with such offering.

         3.7 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 3.2, 3.3 or
3.4 that CBS shall furnish to the Company such information regarding itself,
the Registrable Securities held by it, and the intended method of disposition
of such securities as shall be required to timely effect the registration of
its Registrable Securities.

         3.8 Delay of Registration. CBS shall not have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 3.

         3:9 Indemnification. In the event any Registrable Securities are
included in a registration statement under Sections 3.2, 3.3 or 3.4:

              (a) By the Company. To the extent permitted by law. the Company
will indemnify and hold harmless CBS, its officers and directors, any
underwriter (as deemed in the Securities Act) for CBS and each person, if any,
who controls CBS or any such underwriter within the meaning of the Securities
Act or the Securities Exchange Act of 1934, as amended (the "1934 Act"),
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the Securities Act, the 1934 Act or other federal
or state law, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"): (i) any
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto: (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein, or necessary to make the statements therein not misleading, or
(iii) any violation or alleged violation by the Company of the Securities Act,
the 1934 Act, any federal or state securities law or any rule or regulation
promulgated under the Securities Act, the 1934 Act or any federal or state
securities law in connection with the offering covered by such registration
statement; and the Company will reimburse CBS and each such officer or
director, underwriter or controlling person for any legal or other expenses
reasonably incurred by them, as



                                       7
<PAGE>   65

incurred, in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the indemnity agreement
contained in this subsection 3.9(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
to CBS or any such officer or director, underwriter or controlling person for
any such loss, claim, damage, liability or action to the extent that it arises
out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by CBS or such officer, director or controlling person.

              (b) By CBS. To the extent permitted by law, CBS will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the Securities Act, any underwriter and any other
holder selling securities under such registration statement or any of such
other holder's partners, directors or officers or any person who controls such
holder within the meaning of the Securities Act or the 1934 Act, against any
losses, claims, damages or liabilities to which the Company or any such
director, officer, controlling person, underwriter or such holder, partner or
director, officer or controlling person of such other holder may become subject
under the Securities Act, the 1934 Act or other: federal or stare law, insofar
as such losses, claims, damages or liabilities (or actions in respect thereto)
arise out of or are based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by CBS expressly for use in
connection with such registration; and CBS will reimburse any legal or other
expenses reasonably incurred by the Company or any such director, officer,
controlling person, underwriter or other holder, partner, officer, director or
controlling person of such other holder in connection with investigating or
defending any such loss, claim, damage, liability or action, as incurred;
provided, however, that the indemnity agreement contained in this subsection
3.9(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of CBS (which consent shall not be unreasonably withheld); and provided
further, that the total amounts payable in indemnity by CBS under this Section
3.9(b) in respect of any Violation shall not exceed the net proceeds received
by CBS in the registered offering out of which such Violation arises.

              (c) Notice. Promptly after receipt by an indemnified party under
this Section 3.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 3:9,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to he paid
by the indemnifying parry, if representation of such indemnified party by the
counsel retained by the indemnifying parry would be inappropriate due to actual
or potential conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 3:9, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section
3.9.

              (d) Defect Eliminated in Final Prospectus. The foregoing
indemnity agreements of the Company and CBS are subject to the condition that,
insofar as they relate to any Violation made in a preliminary prospectus but
eliminated or remedied in the amended prospectus on file with the SEC at the
time the registration statement in question becomes effective or the amended
prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "Final
Prospectus), such indemnity agreement shall not inure to



                                       8
<PAGE>   66

the benefit of CBS if a copy of the Final Prospectus was furnished to CBS and
was not furnished by CBS to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

              (e) Contribution. In order to provide for just and equitable
contribution to joint liability under the Securities Act in any case in which
either (i) CBS, or any controlling person of CBS, makes a claim for
indemnification pursuant to this Section 3.9 but it is judicially determined
(by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 3.9 provides for indemnification in
such case, or (ii) contribution under the Securities Act may be required on the
part of CBS or any such controlling person in circumstances for which
indemnification is provided under this Section 3.9; then, and in each such
case, the Company and CBS will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from
others and based on equitable considerations) in such proportion so that CBS is
responsible for the portion represented by the percentage that the public
offering price of its Registrable Securities offered by and sold under the
registration statement bears to the public offering price of all securities
offered by and sold under such registration statement, and the Company and
other selling holders are responsible for the remaining portion; provided,
however, that, in any such case, (A) CBS will not be required to contribute any
amount in excess of the net proceeds received by CBS from the offering pursuant
to such registration statement; and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any person or entity who
was not guilty of such fraudulent misrepresentation.

              (f) Survival. The obligations of the Company and CBS under this
Section 3.9 shall survive the completion of any offering of Registrable
Securities in a registration statement, and otherwise.

              (g) Conflict with Underwriting Agreement. In the event of any
conflict between the indemnity provisions of this Agreement and those of any
underwriting agreement entered into by the Company, CBS and any other holders
with respect to a registration of Registrable Securities, the provisions of the
underwriting agreement shall supersede and control.

         3.10 "Market Stand-Off" Agreement. CBS hereby agrees that it shall not,
to the extent requested by the Company or an underwriter of securities of the
Company, sell or otherwise transfer or dispose of any Registrable Securities or
other shares of stock of the Company owned by CBS for up to one hundred eighty
(180) days following the effective date of a registration statement of the
Company filed under the Securities Act; provided, however, that (a) such
agreement shall be applicable only to the first two such registration
statements of the Company which cover securities to be sold on its behalf to
the public in an underwritten offering but not to Registrable Securities sold
pursuant to such registration statement, and (b) all executive officers and
directors and, to the extent finally required by the Company's underwriters,
employees of the Company then holding Common Stock of the Company enter into or
become bound by similar agreements. In order to enforce the foregoing covenant,
the Company shall have the right to place restrictive legends on the
certificates representing the shares subject to this Section and to impose stop
transfer instructions with respect to the Registrable Securities and such
other shares of stock of CBS until the end of such period.

         3.11 Rule 144 Reporting. With a view to making available the benefits
of certain rules and regulations of the Commission which may at any time
permit the sale of the Registrable Securities to the public without
registration, after such time as a public market exists for the Common Stock of
the Company, the Company agrees to:




                                       9
<PAGE>   67

              (a) Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, after the
effective date of the first registration under the Securities Act filed by the
Company for an offering of its securities to the general public;

              (b) Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the 1934 Act (at any time after it has become subject to
such reporting requirements); and

              (c) So long as CBS owns any Registrable Securities, to furnish to
CBS upon request a written statement by the Company as to its compliance with
the reporting requirements of said Rule 144 (at any time after 90 days after
the effective date of the first registration statement filed by the Company
for an offering of its securities to the general public), and of the Securities
Act and the 1934 Act (at any time after it has become subject to the reporting
requirements of the 1934 Act), a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents of the Company as
CBS may reasonably request in availing itself of any rule or regulation of the
Commission allowing CBS to sell any such securities without registration (at
any time after the Company has become subject to the reporting requirements of
the 1934 Act).

         3.12 Termination of the Company's Obligations. The Company shall have
no obligations pursuant to Sections 3.2 through 3.5 with respect to: (i) any
request or requests for registration made by CBS on a date more than five (5)
years after the closing date of the Company's initial public offering; or (ii)
any Registrable Securities proposed to be sold by CBS in a registration
pursuant to Section 3.2, 3.3 or 3.4 if, in the opinion of counsel to the
Company, all such Registrable Securities proposed to be sold by CBS may be sold
in a three-month period without registration under the Securities Act pursuant
to Rule 144 under the Securities Act.

         3.13 Limitations on Subsequent Registration Rights. From and after the
date of this Agreement, the Company shall not, without the prior written
consent of CBS, enter into any agreement with any holder or prospective holder
of any securities of the Company which would allow such holder or prospective
holder to include such securities in any registration filed under Section 3.2
hereof, unless under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent
that the inclusion of his securities will not reduce the amount of the
Registrable Securities of CBS which are included.

4.       ASSIGNMENT; AMENDMENT; TERMINATION OF CERTAIN RIGHTS.

         4.1 Assignment. Neither party shall assign this Agreement or any of
its rights or obligations hereunder, in whole or in part, without the other
party's prior written consent; provided, that in the event CBS assigns its
rights under the Principal Agreement to a CBS Assignee, such CBS Assignee shall
succeed to all of CBS's rights under this Agreement, subject to CBS's
obligations hereunder.

         4.2 Amendment of Rights. Any provision of this Agreement may be
amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only by a
written instrument executed by the Company and CBS. Any amendment or waiver
effected in accordance with this Section 4.2 shall be binding upon the Company,
CBS and each permitted successor or assignee of each of the foregoing.

         4.3 Termination of Certain Rights. The rights of CBS under Sections
1.1, 1.2, 1.3, 2.1, 2.3 and 2.4 hereof, and the Company's obligations under
such sections, shall terminate (i) immediately upon the closing of the first
underwritten sale of Common Stock of the Company to the public pursuant to a
registration statement filed with, and declared effective by, the SEC under the
Securities Act, covering the offer and sale of Common Stock to the public, or
(ii) upon (a) the acquisition of all or substantially


                                       10
<PAGE>   68

all the assets of the Company or (b) an acquisition of the Company by another
corporation or entity by consolidation, merger or other reorganization in which
the holders of the Company's outstanding voting stock immediately prior to such
transaction own, immediately after such transaction, securities representing
less than fifty percent (50%) or more of the voting power of the corporation or
other entity surviving such transaction. Notwithstanding clause (i) above, if
the Preferred Stock Holders retain their rights of first refusal to purchase
New Securities after the Company's initial public offering pursuant to the
terms of the Investors' Rights Agreement, then the rights of CBS under Section
2 of this Agreement shall continue in effect until such time as the rights of
first refusal of the Preferred Stock Holders are terminated.

laws and choice of law.

         5.4 Severability. If one or more provisions of this Agreement are held

                      CBS/SPORTSLINE STOCKHOLDER AGREEMENT


     This CBS/SPORTSLINE STOCKHOLDER AGREEMENT (this "Agreement") is made and
entered into as of March 5, 1997, between SportsLine USA, Inc., a Delaware
corporation (the "Company"), and CBS INC., a New York corporation ("CBS").

                                R E C I T A L S

     A.   CBS and the Company have entered into that certain Agreement, dated
as of the date hereof (the "Principal Agreement;" capitalized terms used herein
and not otherwise defined shall have the meanings defined in the Principal
Agreement), pursuant to which, among other things, CBS will acquire shares of
Common Stock and Warrants in consideration of the license by CBS of the CBS
Logos and the CBS Content and provision by CBS of certain broadcast advertising
and promotion.

     B.   CBS and the Company have agreed that the terms and conditions of this
Agreement shall govern CBS's rights with respect to the shares of Common Stock
it acquires pursuant to the Principal Agreement or upon the exercise of the
Warrants.

     NOW THEREFORE, in consideration of the above recitals and the mutual
covenants made herein, the parties hereby agree as follows:

1.   INFORMATION AND DIRECTOR RIGHTS.

     1.1  Financial and Other Information. The Company covenants and agrees
that, so long as the CBS Percentage (as defined in Section 1.3 hereof) is at
least ten percent (10%), the Company will furnish to CBS such financial and
other information (including annual, quarterly and monthly reports and an
annual budget) as the Company may from time to time be acquired to furnish to
the holders of the Company's outstanding Series A, Series B or Series C
preferred stock (the "Preferred Stock Holders") pursuant to the Amended and
Restated Investors' Rights Agreement dated as of September 25, 1996, among the
Company, the holders of the Preferred Stock, The Estate of Burk Zanft and
Michael Levy, as now in effect and as hereinafter amended from time to time in
accordance with the terms thereof (the "Investors' Rights Agreement"). Such
financial and other information shall be provided to CBS by the Company at such
time or times and in the same manner as it is provided to the Preferred Stock
Holders in accordance with the Investors' Rights Agreement. CBS agrees to hold
all such financial and other information received pursuant to this Section 1.1
in confidence, and not to use or disclose any of such information to any third
party (other than to any regulatory authority to which CBS is subject
requesting the same), except to the extent such information may be made publicly
available by the Company.

     1.2  CBS Designees. So long as the CBS Percentage is at least ten percent
(10%), CBS shall have the right to elect (and maintain in office) as members of
the Company's Board of Directors (the "Board") a number of individuals equal to
the product of (i) total number of members of the Board, times (ii) the CBS
Percentage (the "CBS Designees"). The CBS Designees shall be designated from
time to time in writing by CBS. Upon execution of this Agreement, the Company
shall cause two (2) CBS Designees to be appointed to the Board. The Company
further agrees to use its best efforts to cause the nomination and election
from time to time of the CBS Designees, including obtaining the agreement of the
holders of a majority of its outstanding Common Stock and preferred stock to
vote their shares of the Company's capital stock to cause the election to the
Board of any CBS Designees designated for election to the Board by CBS.

     1.3  Observer Rights. If CBS is no longer entitled to appoint CBS
Designees in accordance with Section 1.2, then so long as CBS owns not less
than 250,000 shares of Common Stock, CBS, at its own expense, shall be entitled
to have a representative attend all meetings of the Company's Board of
Directors in a nonvoting observer capacity (each, a "CBS Representative"). If
CBS designates a CBS Representative to the Company, the Company shall
concurrently provide the CBS Representative with

<PAGE>   2

copies of all notices, minutes, consents and other materials it provides to
members of the Board of Directors; provided, that the CBS Representative shall
agree to hold in confidence and trust and to act in a fiduciary manner with
respect to all information so provided; and provided further, that the Company
reserves the right to withhold any information and to exclude any CBS
Representative from any meeting or portion thereof if access to such
information or meeting or attendance at such meeting could adversely affect the
attorney-client privilege between the Company and its counsel or would result
in disclosure of trade secrets to any CBS Representative.

     1.4  CBS Percentage. For purposes of this Agreement, the term "CBS
Percentage" shall mean, at any particular time, that percentage determined by
dividing (a) the sum of (i) the number of shares of Common Stock CBS then
holds, plus (ii) the number of shares of Common Stock which CBS thereafter has
the right to acquire under the Principal Agreement or upon exercise of any
Warrants outstanding or to be granted thereunder, by (b) the sum of (i) the
total number of shares of Common Stock of the Company then outstanding plus
(ii) the total number of shares of Common Stock of the Company into which all
then outstanding shares of preferred stock of the Company are then convertible
plus (iii) the number of shares of Common Stock of the Company reserved for
issuance under stock purchase and stock option plans of the Company and
outstanding options and warrants.

2.   RIGHT OF FIRST REFUSAL.

     2.1  General. CBS shall have the right of first refusal to purchase the CBS
Percentage of all (or any part) of any New Securities that the Company may from
time to time issue after the date of this Agreement.

     2.2  New Securities. "New Securities" shall mean any Common Stock or
preferred stock of the Company, whether now authorized or not, and rights,
options or warrants to purchase such Common Stock or preferred stock, and
securities of any type whatsoever that are, or may become, convertible or
exchangeable into such Common Stock or preferred stock; provided, however, that
the term "New Securities" does not include: (i) shares of the Company's Common
Stock (and/or options or warrants therefor) issued to employees, officers,
directors, contractors, advisors or consultants of the Company pursuant to
incentive agreements or plans unanimously approved by the Board of Directors of
the Company ("Employee Options"); (ii) any securities issuable upon conversion
of or with respect to any then outstanding shares of the Company's Series A,
Series B or Series C preferred stock or Common Stock or other securities
issuable upon conversion thereof; (iii) any securities issuable upon exercise
of any of the options, warrants or rights (other than Employee Options)
("Warrant Securities") outstanding as of the date hereof, any Warrant
Securities hereafter unanimously approved by the Board of Directors of the
Company, and any Common Stock or other securities issuable upon the conversion
of any Warrant Securities; (iv) shares of the Company's Common Stock or
preferred stock issued in connection with any stock split or stock dividend;
(v) securities offered by the Company to the public pursuant to a registration
statement filed under the Securities Act; (vi) up to 50,000 shares of the
Company's Common Stock (and/or options or warrants therefor) issued or issuable
to nonaffiliate third parties providing the Company with equipment leases, real
property leases, loans, credit lines, guaranties of indebtedness, cash price
reductions or similar financing, provided that this exception (vi) shall not
apply unless the arrangement is unanimously approved by the Company's Board of
Directors; or (vii) securities issued pursuant to the acquisition of another
corporation or entity by the Company by consolidation, merger, purchase of all
or substantially all of the assets, or other reorganization in which the
Company acquires, in a single transaction or series of related transactions,
all or substantially all of the assets of such other corporation or entity or
fifty percent (50%) or more of the voting power of such other corporation or
entity or fifty percent (50%) or more of the equity ownership of such other
entity.

     2.3  Procedures. In the event that the Company proposes to undertake an
issuance of New Securities, it shall give CBS written notice of its intention
to issue New Securities (the "Notice"),


                                       2
<PAGE>   3
describing the type of New Securities and the price and the general terms upon
which the Company proposes to issue such New Securities. CBS shall have fifteen
(15) days from the date of mailing of any such Notice to agree in writing to
purchase the CBS Percentage of such New Securities for the price and upon the
general terms specified in the Notice by giving written notice to the Company
and stating therein the quantity of New Securities to be purchased (not to
exceed the CBS Percentage).

     2.4  Failure to Exercise. In the event that CBS fails to exercise the
right of first refusal within such fifteen (15) day period, then the Company
shall have 120 days thereafter to sell the New Securities with respect to which
CBS's rights of first refusal hereunder were not exercised, at a price and upon
general terms not materially more favorable to the purchasers thereof than
specified in the Notice. In the event that the Company has not issued and sold
the New Securities within such 120 day period, then the Company shall not
thereafter issue or sell any New Securities without again first offering such
New Securities to CBS pursuant to this Section 2.

3.   REGISTRATION RIGHTS.

     3.1  Definitions. For purposes of this Section 3:

          (a)  Registration. The terms "register," "registered," and
"registration" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act of 1933, as
amended (the "Securities Act"), and the declaration or ordering of
effectiveness of such registration statement.

          (b)  Registrable Securities. The term "Registrable Securities" means:
all shares of Common Stock (i) issued by the Company to CBS as Content Shares
or Ad Shares pursuant to the Principal Agreement, (ii) issuable upon the
exercise of outstanding and exercisable Warrants granted pursuant to the
Principal Agreement, and (iii) any shares of Common Stock of the Company issued
as (or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to,
or in exchange for or in replacement of, all such shares of Common Stock
described in clause (i) or (ii) of this Section 3.1(b); excluding in all cases,
however, any Registrable Securities sold by CBS in a transaction in which
rights under this Section 3 are not assigned in accordance with this Agreement
or any Registrable Securities sold to the public or sold pursuant to Rule 144
promulgated under the Securities Act.

          (c)  Registrable Securities Then Outstanding. The number of shares of
"Registrable Securities then outstanding" shall mean the number of shares of
Common Stock which are Registrable Securities and (1) are then issued and
outstanding or (2) are then issuable pursuant to the exercise or conversion of
then outstanding and then exercisable options, warrants or convertible
securities.

          (d)  Form S-3. The term "Form S-3" means such form under the
Securities Act as is in effect on the date hereof or any successor registration
form under the Securities Act subsequently adopted by the SEC which permits
inclusion or incorporation of substantial information by reference to other
documents filed by the Company with the SEC.

          (e)  SEC. The term "SEC" or "Commission" means the United States
Securities and Exchange Commission.

     3.2  Demand Registration. If the Company shall receive at any time six
months or more after the effective date of the Company's initial public
offering of its securities pursuant to a registration filed under the
Securities Act a written request from CBS that the Company file a registration
statement under the Securities Act covering the registration of Registrable
Securities pursuant to this Section 3.2, then the Company shall effect, as soon
as practicable and in any event within sixty (60) days of the 


                                       3
<PAGE>   4
receipt of such request, the registration under the Securities Act of all
Registrable Securities which CBS requests to be registered and included in such
registration by such written notice, subject only to the limitations of this
Section 3.2; provided that the Registrable Securities requested by CBS to be
registered pursuant to such request must have an anticipated aggregate public
offering price (before any underwriting discounts and commissions) of not less
than $5,000,000.

     If CBS intends to distribute the Registrable Securities covered by its
request by means of an underwriting, then CBS shall so advise the Company as
a part of its request made pursuant to this Section 3.2. The underwriter shall
be selected by the Company with the consent of CBS, which consent will not
unreasonably be withheld, and CBS shall enter into an underwriting agreement in
customary form with the managing underwriter or underwriters selected for such
underwriting by the Company. Notwithstanding any other provision of this
Section 3.2, if the underwriter(s) advise(s) the Company in writing that
marketing factors require a limitation of the number of securities to be
underwritten then the Company shall so advise CBS, and the number of
Registrable Securities that may be included in the underwriting shall be
reduced as required by the underwriter(s) and allocated first, to the Company,
second, to the Preferred Stock Holders, if and to the extent such Preferred
Stock Holders have exercised their registration rights granted under the
Investors' Rights Agreement, and third, if and only to the extent that the
inclusion of such Registrable Securities will not reduce the amount of the
shares that the Preferred Stock Holders may include in such registration and
underwriting, to CBS; provided, however, that the managing underwriter(s) shall
have the absolute right and discretion to exclude from a registration and
underwriting relating to the Company's initial public offering any and all of
the Registrable Securities. Any Registrable Securities excluded and withdrawn
from such underwriting shall be withdrawn from the registration.

     The Company is obligated to effect only one (1) registration pursuant to
this Section 3.2. The Company shall not be deemed to have effected a
registration pursuant to this Section 3.2 unless a registration statement in
respect thereof shall have been declared effective by the Commission.

     Notwithstanding the foregoing, if the Company shall furnish to CBS a
certificate signed by the President or Chief Executive Officer of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such registration statement to be filed and it is therefore essential to
defer the filing of such registration statement, then the Company shall have
the right to defer such filing for a period of not more than 120 days after
receipt of the request of CBS; provided, however, that the Company may not
utilize this right more than once in any twelve (12) month period.

     3.3  Piggyback Registrations. The Company shall notify CBS in writing at
least thirty (30) days prior to filing any registration statement under the
Securities Act for purposes of effecting a public offering of securities of the
Company (including registration statements relating to secondary offerings of
securities of the Company but excluding registration statements relating to
offerings of securities pursuant to any employee benefit plan or a corporate
reorganization) and will afford CBS an opportunity to include in such
registration statement all or any part of the Registrable Securities then held
by CBS. If CBS desires to include in any such registration statement all or any
part of the Registrable Securities then held by it, CBS shall, within twenty
(20) days after receipt of the above-described notice from the Company, so
notify the Company in writing, and in such notice shall inform the Company of
the number of Registrable Securities CBS wishes to include in such registration
statement. If CBS decides not to include all of its Registrable Securities in
any registration statement thereafter filed by the Company, CBS shall
nevertheless continue to have the right to include any Registrable Securities
in any subsequent registration statement or registration statements as may be
filed by the Company with respect to offerings of its securities, all upon the
terms and conditions set forth herein.


                                       4
<PAGE>   5

     If a registration statement under which the Company gives notice under
this Section 3.3 is for an underwritten offering, then the Company shall so
advise CBS. In such event, the right of CBS to have any of its Registrable
Securities included in a registration pursuant to this Section 3.3 shall be
conditioned upon CBS's participation in such underwriting and the inclusion of
CBS's Registrable Securities in the underwriting to the extent provided herein.
CBS and any other stockholders proposing to distribute their Company securities
through such underwriting shall enter into an underwriting agreement in
customary form with the managing underwriter or underwriter(s) selected for
such underwriting. Notwithstanding any other provision of this Agreement, if
the managing underwriter determine(s) in good faith that marketing factors
require a limitation of the number of shares to be underwritten, then the
managing underwriter(s) may exclude shares (including Registrable Securities)
from the registration and the underwriting, and the number of shares that may
be included in the registration and the underwriting shall be allocated, first,
to the Company, second, to the Preferred Stock Holders, if and to the extent
such Preferred Stock Holders have exercised their registration rights granted
under the Investors' Rights Agreement, and third, if and only to the extent
that the inclusion of such Registrable Securities will not reduce the amount of
the shares that the Preferred Stock Holders may include in such registration
and underwriting, to CBS; provided, however, that the managing underwriter(s)
shall have the absolute right and discretion to exclude from a registration and
underwriting relating to the Company's initial public offering any and all of
the Registrable Securities. If CBS disapproves of the terms of any such
underwriting, CBS may elect to withdraw therefrom by written notice to the
Company and the underwriter(s), delivered at least ten (10) business days prior
to the effective date of the registration statement. Any Registrable Securities
excluded or withdrawn from such underwriting shall be excluded and withdrawn
from the registration.

     3.4  Form S-3 Registration. In case the Company shall receive from CBS a
written request or requests that the Company effect a registration on Form S-3
and any related qualification or compliance with respect to all or a part of
the Registrable Securities then owned by CBS, then the Company will, as soon as
practicable after receipt of the request, file a Form S-3 registration
statement covering such Registrable Securities and effect such registration and
all such qualifications and compliances as may be so requested and as would
permit or facilitate the sale and distribution of such Registrable Securities,
together with the securities of any holders of securities of the Company (other
than CBS) entitled to inclusion in such registration; provided, however, that
the Company shall not be obligated to effect any such registration,
qualification or compliance pursuant to this Section 3.4;

               (i)    if the Company is not then eligible for the use of Form
S-3, or if Form S-3 is not available for such offering by CBS;

               (ii)   if CBS, together with the holders of any other securities
of the Company entitled to inclusion in such registration, propose to sell
Registrable Securities and such other securities (if any) at an aggregate price
to the public of less than $1,000,000;

               (iii)  if the Company shall furnish to CBS a certificate signed
by the President or Chief Executive Officer of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such Form S-3
Registration to be effected at such time, in which event the Company shall have
the right to defer the filing of the Form S-3 registration statement no more
than once during any twelve month period for a period of not more than 120 days
after receipt of the request of CBS under this Section 3.4;

               (iv)   if the Company has, within the twelve (12) month period
preceding the date of such request, already effected two (2) registrations on
Form S-3 for CBS or other holders of its securities; or


                                       5
<PAGE>   6

               (v)    in any particular jurisdiction in which the Company would
be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance.

     A Form S-3 registration effected pursuant to this Section 3.4 shall not be
deemed to be demand registration as described in Section 3.3 above.

     3.5  Obligations of the Company. Whenever required to effect the
registration of any Registrable Securities under this Agreement, the Company
shall, as expeditiously as reasonably possible:

          (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of CBS, keep
such registration statement effective for up to one hundred twenty (120) days
or until the distribution contemplated in the Registration Statement has been
completed, whichever is earlier; provided, however, that such one hundred
twenty day (120) shall be extended for a period of time equal to the period CBS
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company.

          (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by
such registration statement.

          (c)  Furnish to CBS such number of copies of a prospectus, including
a preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of the Registrable Securities owned by CBS that are
included in such registration.

          (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by CBS, provided
that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdictions.

          (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter(s) of such offering. CBS and any other
holders of securities of the Company included in such registration and
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

          (f)  Notify CBS at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

          (g)  Furnish, at the request of CBS, on the date that such
Registrable Securities are delivered to the underwriters for sale, if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the registration statement
with respect to such securities becomes effective, (i) an opinion, dated as of
such date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering and reasonably satisfactory to CBS, addressed
to the

                                       6
<PAGE>   7
underwriters, if any, and CBS and any other stockholders requesting
registration of securities in such registration, and (ii) a "comfort" letter
dated as of such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering and
reasonably satisfactory to CBS and any other stockholders requesting
registration of securities in such registration, addressed to the underwriters,
if any, and to CBS and such other stockholders.

          (h)  Cause the Registrable Securities registered pursuant hereto to be
listed on each securities exchange or market on which similar securities issued
by the Company are then listed.

          (i)  Provide a transfer agent and registrar for all Registrable 
Securities registered pursuant hereunder and a CUSIP number for all such 
Registrable Securities, in each case not later than the effective date of such 
registration.

     3.6  Expenses. All expenses incurred by the Company in connection with a
registration pursuant to Section 3.2, 3.3 or 3.4 (excluding underwriters' and
brokers' discounts and commissions), including, without limitation all federal
and "blue sky" registration and qualification fees, printing expenses, fees and
disbursements of the Company's accountants and counsel, and reasonable fees and
disbursements of one counsel for CBS and all other selling stockholders, shall
be borne by the Company. CBS and each other stockholder participating in a
registration pursuant to Section 3.2, 3.3 or 3.4 shall bear their proportionate
share (based on the total number of shares sold in such registration other than
for the account of the Company) of all discounts and commissions payable to
underwriters or brokers in connection with such offering.

     3.7  Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 3.2, 3.3 or
3.4 that CBS shall furnish to the Company such information regarding itself,
the Registrable Securities held by it, and the intended method of disposition
of such securities as shall be required to timely effect the registration of
its Registrable Securities.

     3.8  Delay of Registration. CBS shall not have any right to obtain or seek
an injunction restraining or otherwise delaying any such registration as the
result of any controversy that might arise with respect to the interpretation
or implementation of this Section 3.

     3.9  Indemnification. in the event any Registrable Securities are included
in a registration statement under Sections 3.2, 3.3 or 3.4:

          (a)  By the Company. To the extent permitted by law, the Company will 
indemnify and hold harmless CBS, its officers and directors, any underwriter (as
deemed in the Securities Act) for CBS and each person, if any, who controls CBS 
or any such underwriter within the meaning of the Securities Act or the 
Securities Exchange Act of 1934, as amended (the "1934 Act"), against any 
losses, claims, damages, or liabilities (joint or several) to which they may 
become subject under the Securities Act, the 1934 Act or other federal or state 
law, insofar as such losses, claims, damages, or liabilities (or actions in 
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement 
or alleged untrue statement of a material fact contained in such registration 
statement, including any preliminary prospectus or final prospectus contained 
therein or any amendments or supplements thereto; (ii) the omission or alleged 
omission to state therein a material fact required to be stated therein, or 
necessary to make the statements therein not misleading, or (iii) any violation 
or alleged violation by the Company of the Securities Act, the 1934 Act, any 
federal or state securities law or any rule or regulation promulgated under the 
Securities Act, the 1934 Act or any federal or state securities law in 
connection with the offering covered by such registration statement; and the 
Company will reimburse CBS and each such officer or director, underwriter or 
controlling person for any legal or other expenses reasonably incurred by them, 
as




                                       7
<PAGE>   8
incurred, in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the indemnity agreement
contained in this subsection 3.9(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
to CBS or any such officer or director, underwriter or controlling person for
any such loss, claim, damage, liability or action to the extent that it arises
out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by CBS or such officer, director or controlling person.

          (b)  By CBS. To the extent permitted by law, CBS will indemnify and
hold harmless the Company, each of its directors, each of its officers who have
signed the registration statement, each person, if any, who controls the
Company within the meaning of the Securities Act, any underwriter and any other
holder selling securities under such registration statement or any of such
other holder's partners, directors or officers or any person who controls such
holder within the meaning of the Securities Act or the 1934 Act, against any
losses, claim, damages or liabilities to which the Company or any such
director, officer, controlling person, underwriter or such holder, partner or
director, officer or controlling person of such other holder may become subject
under the Securities Act, the 1934 Act or other federal or state law, insofar
as such losses, claims, damages or liabilities (or actions in respect thereto)
arise out of or are based upon any violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by CBS expressly for use in
connection with such registration; and CBS will reimburse any legal or other
expenses reasonably incurred by the Company or any such director, officer,
controlling person, underwriter or other holder, partner, officer, director or
controlling person of such other holder in connection with investigating or
defending any such loss, claim, damage, liability or action, as incurred;
provided, however, that the indemnity agreement contained in this subsection
3.9(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of CBS (which consent shall not be unreasonably withheld); and provided
further, that the total amounts payable in indemnity by CBS under this Section
3.9(b) in respect of any Violation shall not exceed the net proceeds received by
CBS in the registered offering out of which such Violation arises.

          (c)  Notice. Promptly after receipt by an indemnified party under
this Section 3.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 3.9,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 3.9, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 3.9.

          (d)  Defect Eliminated in Final Prospectus. The foregoing indemnity
agreements of the Company and CBS are subject to the condition that, insofar as
they relate to any Violation made in a preliminary prospectus but eliminated or
remedied in the amended prospectus on file with the SEC at the time the
registration statement in question becomes effective or the amended prospectus
filed with the SEC pursuant to SEC Rule 424(b) (the "Final Prospectus"), such
indemnity agreement shall not inure to



                                       8
<PAGE>   9
the benefit of CBS if a copy of the Final Prospectus was furnished to CBS and
was not furnished by CBS to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

          (e)  Contribution. In order to provide for just and equitable
contribution to joint liability under the Securities Act in any case in which
either (i) CBS, or any controlling person of CBS, makes a claim for
indemnification pursuant to this Section 3.9 but it is judicially determined
(by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 3.9 provides for indemnification in
such case, or (ii) contribution under the Securities Act may be required on the
part of CBS or any such controlling person in circumstances for which
indemnification is provided under this Section 3.9; then, and in each such
case, the Company and CBS will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from
others and based on equitable considerations) in such proportion so that CBS is
responsible for the portion represented by the percentage that the public
offering price of its Registrable Securities offered by and sold under the
registration statement bears to the public offering price of all securities
offered by and sold under the registration statement bears to the public
offering price of all securities offered by and sold under such registration
statement, and the Company and other selling holders are responsible for the
remaining portion; provided, however, that, in any such case, (A) CBS will not
be required to contribute any amount in excess of the net proceeds received by
CBS from the offering pursuant to such registration statement; and (B) no
person or entity guilty of fraudulent misrepresentation (within the meaning of
Section 11 (f) of the Securities Act) will be entitled to contribution from any
person or entity who was not guilty of such fraudulent misrepresentation.

          (f)  Survival. The obligations of the Company and CBS under this
Section 3.9 shall survive the completion of any offering of Registrable
Securities in a registration statement, and otherwise.

          (g)  Conflict with Underwriting Agreement. In the event of any
conflict between the indemnity provisions of this Agreement and those of any
underwriting agreement entered into by the Company, CBS and any other holders
with respect to a registration of Registrable Securities, the provisions of the
underwriting agreement shall supersede and control.

     3.10  "Market Stand-Off" Agreement. CBS hereby agrees that it shall not,
to the extent requested by the Company or an underwriter of securities of the
Company, sell or otherwise transfer or dispose of any Registrable Securities or
other shares of stock of the Company owned by CBS for up to one hundred eighty
(180) days following the effective date of a registration statement of the
Company filed under the Securities Act; provided, however, that (a) such
agreement shall be applicable only to the first two such registration
statements of the Company which cover securities to be sold on its behalf to
the public in an underwritten offering but not to Registrable Securities sold
pursuant to such registration statement, and (b) all executive officers and
directors and, to the extent finally required by the Company's underwriters,
employees of the Company then holding Common Stock of the Company enter into or
become bound by similar agreements. In order to enforce the foregoing covenant,
the Company shall have the right to place restrictive legends on the
certificates representing the shares subject to this Section and to impose stop
transfer instructions with respect to the Registrable Securities and such other
shares of stock of CBS until the end of such period.

     3.11  Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit
the sale of the Registrable Securities to the public without registration,
after such time as a public market exists for the Common Stock of the Company,
the Company agrees to:

                                       9
<PAGE>   10
          (a)  Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, after the
effective date of the first registration under the Securities Act filed by the
Company for an offering of its securities to the general public;

          (b)  Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the 1934 Act (at any time after it has become subject to
such reporting requirements); and

          (c)  So long as CBS owns any Registrable Securities, to furnish to CBS
upon request a written statement by the Company as to its compliance with the
reporting requirements of said Rule 144 (at any time after 90 days after the
effective date of the first registration statement filed by the Company for an
offering of its securities to the general public), and of the Securities Act and
the 1934 Act (at any time after it has become subject to the reporting
requirements of the 1934 Act), a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents of the Company as
CBS may reasonably request in availing itself of any rule or regulation of the
Commission allowing CBS to sell any such securities without registration (at any
time after the Company has become subject to the reporting requirements of the
1934 Act).

     3.12  Termination of the Company's Obligations. The Company shall have no
obligations pursuant to Sections 3.2 through 3.5 with respect to: (i) any
request or requests for registration made by CBS on a date more than five (5)
years after the closing date of the Company's initial public offering; or (ii)
any Registrable Securities proposed to be sold by CBS in a registration
pursuant to Section 3.2, 3.3 or 3.4 if, in the opinion of counsel to the
Company, all such Registrable Securities proposed to be sold by CBS may be sold
in a three-month period without registration under the Securities Act pursuant
to Rule 144 under the Securities Act.

     3.13  Limitations on Subsequent Registration Rights. From and after the
date of this Agreement, the Company shall not, without the prior written
consent of CBS, enter into an agreement with any holder or prospective holder
of any securities of the Company which would allow such holder or prospective
holder to include such securities in any registration filed under Section 3.2
hereof, unless under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent
that the inclusion of his securities will not reduce the amount of the
Registrable Securities of CBS which are included.

4.  ASSIGNMENT; AMENDMENT; TERMINATION OF CERTAIN RIGHTS.

     4.1  Assignment. Neither party shall assign this Agreement or any of its
rights or obligations hereunder, in whole or in part, without the other party's
prior written consent; provided, that in the event CBS assigns its rights under
the Principal Agreement to a CBS Assignee, such CBS Assignee shall succeed to
all of CBS's rights under this Agreement, subject to CBS's obligations
hereunder.

     4.2  Amendment of Rights. Any provision of this Agreement may be amended
and the observance thereof may be waived (either generally or in a particular
instance and either retroactively or prospectively), only by a written
instrument executed by the Company and CBS. Any amendment or waiver effected in
accordance with this Section 4.2 shall be binding upon the Company, CBS and
each permitted successor or assignee of each of the foregoing.

     4.3  Termination of Certain rights. The rights of CBS under Sections 1.1,
1.2, 1.3, 2.1, 2.3 and 2.4 hereof, and the Company's obligations under such

underwritten sale of Common Stock of the Company to the public pursuant to a
registration statement filed with, and declared effective by, the SEC under the
Securities Act, covering the offer and sale of Common Stock to the public, or
(ii) upon (a) the acquisition of all or substantially

                                       10

all the assets of the Company or (b) an acquisition of the Company by another
corporation or entity by consolidation, merger or other reorganization in which
the holders of the Company's outstanding voting stock immediately prior to such
transaction own, immediately after such transaction, securities representing
less than fifty percent (50%) or more of the voting power of the corporation or
other entity surviving such transaction. Notwithstanding clause (i) above, if
the Preferred Stock Holders retain their rights of first refusal to purchase
New Securities after the Company's initial public offering pursuant to the
terms of the Investors' Rights Agreement, then the rights of CBS under Section
2 of this Agreement shall continue in effect until such time as the rights of
first refusal of the Preferred Stock Holders are terminated.

                               CO-SALE AGREEMENT


     This Co-Sale Agreement (this "Agreement") is made and entered into as of
March 5, 1997 by and between SportsLine USA, Inc., a Delaware corporation (the
"Company"), (ii) CBS, Inc. ("CBS") and (iii) Michael Levy ("Levy").

                                R E C I T A L S

     A.  Concurrently herewith, CBS and the Company are entering into that
certain Agreement, dated as of the date hereof (the "Principal Agreement;"
capitalized terms used herein and not otherwise defined shall have the meanings
defined in the Principal Agreement), pursuant to which, among other things, CBS
will acquire shares of Common Stock and Warrants in consideration of the
license by CBS of the CBS Logos and the CBS Content and provision by CBS of
certain broadcast advertising and promotion.

     B.  To induce CBS to enter into the Principal Agreement, Levy has agreed
to enter into this Agreement and offer CBS the opportunity to participate in
certain sales of his shares of Common Stock of the Company.

     NOW THEREFORE, in consideration of the above recitals and the mutual
covenants made herein, the parties hereby agree as follows:

1.  RIGHT OF CO-SALE.

     1.1  Notice of Sales. In the event Levy proposes to accept one or more
bona fide offers (collectively, the "Purchase Offer") from any persons to
purchase from him shares of the Common Stock of the Company, he promptly shall
give written notice (the "Notice") to CBS describing fully the Purchase Offer,
including the number of shares of Common Stock proposed to be transferred (the
"Shares"), the proposed bona fide transfer price and the name and address of
the proposed transferee. The Notice may be included as a part of any notice
required to be given by Levy under Article Eight, Section 1 of the Company's
Bylaws.

     1.2  Participation Right. To the extent that the Company and other
stockholders of the Company have not exercised their respective rights of first
refusal to purchase the Shares in accordance with Article Eight of the
Company's Bylaws, CBS shall have the right (the "Participation Right") to
participate in Levy's sale of the Shares under the terms and conditions
specified in the Purchase Offer. To the extent CBS exercises its Participation
Rights, the number of Shares which Levy may sell pursuant to the Purchase Offer
shall be correspondingly reduced. The Participation Right of CBS is subject to
the following terms and conditions:

          (a)  Number of Shares. CBS may sell its Pro Rata Share of the Shares
covered by the Purchase Offer. CBS's "Pro Rata Share" for purposes of this
Agreement is that number of shares of Common Stock equal to the product obtained
by multiplying (i) the aggregate number of Shares covered by the Purchase
Offer, times (ii) a fraction, the numerator of which is the sum of the number
of shares of Common Stock at the time owned by CBS and the 
<PAGE>   2
denominator of which is the aggregate number of shares of Common Stock at the
time outstanding, assuming conversion of all outstanding preferred stock of the
Company and the exercise of all options and warrants then outstanding.

          (b)  Exercise Notice. If CBS desires to exercise its Participation
Rights, CBS shall provide Levy, within thirty (30) days after CBS's receipt of
the Notice, a written notice of such election ("Exercise Notice") specifying
the number of shares of Common Stock that CBS elects to sell pursuant to the
Participation Rights. Each Exercise Notice shall be irrevocable, unless
otherwise consented to by Levy.

          (c)  Delivery of Certificates. CBS shall effect its participation in
the sale by delivering to the Company promptly following exercise of its
Participation Right, for delivery to the purchaser of the Shares at the closing
of the transaction contemplated by the Purchase Offer, one or more
certificates, properly endorsed for transfer, representing the number of shares
of Common Stock which CBS has elected to sell pursuant to the Participation
Rights.

          (d)  Transfer of Shares. The stock certificate or certificates which
CBS delivers to the Company pursuant to Section 1.2(c) shall be delivered by
the Company to the purchaser under the Purchase offer at the closing of the
transaction contemplated by the Purchase Offer; and the Company shall receive
on behalf of, and promptly remit to CBS, that portion of the sale proceeds
which CBS is entitled to receive by reason of its participation in the sale.

          (e)  Closing. Whether or not CBS exercises its Participation Rights,
the closing of the sale of the Shares subject to the Purchase Offer shall take
place not later than one hundred twenty (120) days following the date the Notice
was first delivered to CBS. At the closing, Levy may sell any Shares subject to
the Purchase Offer as to which CBS has not exercised its Participation Rights;
and, if CBS has exercised its Participation Rights, the consummation of such
sale shall be subject to the sale by CBS at the closing of all shares of Common
Stock which CBS has elected to sell pursuant to the Participation Rights. Any
proposed sale on terms and conditions materially different from those described
in the Notice, as well as any subsequent proposed sale by Levy, will again
require compliance by Levy with the provisions of this Agreement.

     1.3  Termination. This Agreement and the Participation Rights granted
hereunder shall terminate upon the first to occur of the following: (a) the
tenth anniversary of the date of this Agreement; (b) the execution of a written
agreement to terminate this Agreement by Levy and CBS; (c) the consummation of
the first sale of securities of the Company to the public pursuant to an
effective registration statement filed by the Company under the Securities Act
of 1933, as amended; (d) the first date on which CBS or any assignee to which
such Participation Rights have been assigned pursuant to Section 2.1 hereof (i)
own Common Stock representing less than 10% of the number of shares of the
Company's Common Stock that would be outstanding if all then outstanding shares
of the Company's convertible preferred stock were then converted into shares of
Common Stock or (ii) hold less than 50% of the number of such Common Stock
equivalent shares as are issuable to CBS pursuant to the Principal Agreement or
any Warrants

                                       2
<PAGE>   3
issuable thereunder; or (e) upon the closing of (i) any consolidation or merger
of the Company with or into any other corporation or corporations in which the
holders of the Company's outstanding shares immediately before such
consolidation or merger do not, immediately after such consolidation or merger,
retain stock representing a majority of the voting power of the surviving
corporation of such consolidation or merger or stock representing a majority of
the voting power of a corporation that wholly owns, directly or indirectly, the
surviving corporation of such consolidation or merger; (ii) the sale, transfer
or assignment of securities of the Company representing a majority of the
voting power of all the Company's outstanding voting securities by the holders
thereof to an acquiring party in a single transaction or series of related
transactions; or (iii) the sale of all or substantially all the Company's
assets.

2.  ASSIGNMENT OF PARTICIPATION RIGHTS. The Participation Rights of CBS under
Section 1 hereof may be assigned only to a CBS Assignee; provided, however,
that no such assignment of any of such Participation Rights shall be effective
against the Company or Levy until such time as the Company and Levy are given
written notice by the assigning party stating the name and address of the
assignee and identifying the securities of the Company as to which the rights
in question are being assigned; and provided further, that any such assignee
shall receive such assigned Participation Rights subject to all the terms and
conditions of this Agreement, including without limitation the provisions of
this Section 2.

3.  LEGENDED CERTIFICATES.

          3.1  Legend. Each certificates representing shares of the Common
Stock now or hereafter owned by Levy shall be endorsed with the following
legend:

          "THE SALE OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS
          CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A
          CERTAIN CO-SALE AGREEMENT BY AND AMONG THE SHAREHOLDER, THE
          CORPORATION AND CBS, INC. COPIES OF SUCH AGREEMENT MAY BE
          OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE
          CORPORATION."

          3.2  Removal of Legend. The legend required by Section 3.1 shall be
removed upon termination of this Agreement in accordance with the provisions of
Section 1.3.

4.  GENERAL PROVISIONS.

by hand; (b) three days after mailing, in the case of certified or registered

March 5, 1997

                               SPORTSLINE USA, INC.

               Warrants for the Purchase of Shares of Common Stock
               ---------------------------------------------------

     FOR VALUE RECEIVED, SPORTSLINE USA, INC., a Delaware corporation
("SportsLine" or the "Company"), hereby certifies that CBS INC (the "Holder")
is entitled, subject to the provisions contained herein, to purchase from the
Company 950,000 fully paid and non-assessable shares of Common Stock (as
defined below), subject to adjustment as provided herein, at an exercise price
per share of Common Stock (the "Exercise Price") of $4.00.

     The term "Common Stock" means the Common Stock, par value $.01 per share,
of the Company as constituted on the date hereof. The number of shares of
Common Stock to be received upon the exercise of these Warrants may be adjusted
from time to time as hereinafter set forth. The shares of Common Stock
deliverable upon such exercise, and as adjusted from time to time, are
hereinafter referred to as "Warrant Stock." The term "Other Securities" means
any other securities that may be issued by the Company in addition to, or in
substitution for, the Warrant Stock.

     References herein to the "Company" are to (i) SportsLine and any successor
thereto, (ii) any successor corporation resulting from the merger or
consolidation of SportsLine, or any successor thereto, with another corporation
or (ii) any corporation to which SportsLine, or any successor thereto, has
transferred its property or assets as an entirety or substantially as an
entirety.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of these Warrants, and (in the case
of loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of these Warrants, if mutilated, the Company
shall execute and deliver new Warrants of like tenor and date. Any such new
Warrants, upon execution and delivery, shall constitute an additional
contractual obligation on the part of the Company, whether or not these
Warrants so lost, stolen, destroyed or mutilated shall be at any time
enforceable by anyone.

     The Holder agrees with the Company that these Warrants are issued, and all
the rights hereunder shall be held subject to, all of the conditions, 
limitations and provisions set forth herein, including the following:

     1.   Exercise of Warrants. The Warrants may be exercised, in whole or in
part, at any time prior to December 31, 1997; provided, however, that the
exercisability of the Warrants shall be subject to the condition that the
Agreement dated as of March 5, 1997 between SportsLine and the Holder (the
<PAGE>   2
"Principal Agreement"), as amended or modified, shall be in effect, and no
further Warrants shall be exercisable on or after the expiration, nonrenewal or
termination of said agreement. Subject to the foregoing, the Warrants shall be
exercisable by presentation and surrender of these Warrants to the Company at
its principal office (which on the date hereof is 6340 N.W. 5th Way, Fort
Lauderdale, Florida 33309), or at the office of its stock transfer agent (which
on the date hereof is the Company), if any, with the Warrant Exercise Form
attached hereto duly executed and accompanied by payment (either in cash or by
certified or official bank check or checks, payable to the order of the Company)
of the Exercise Price for the number of shares specified in such form. Upon
receipt by the Company of the Warrants, together with the Exercise Price, at its
office, or by the Company's stock transfer agent at its office, in proper form
for exercise, the Holder shall be deemed to be the holder of record of the
Warrant Stock (and Other Securities) issuable upon such exercise,
notwithstanding that the transfer books of the Company shall then be closed or
that certificates representing such Warrant Stock (or Other Securities) shall
not then be actually delivered to the Holder. The Company shall pay any and all
documentary stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of Warrant Stock (and Other Securities) upon exercise of these
Warrants.

     2.   Reservation of Shares and Other Securities. The Company will at all
times reserve for issuance and delivery upon exercise of these Warrants all
shares of Warrant Stock and other shares of capital stock of the Company (and
Other Securities) from time to time receivable upon exercise of these Warrants.
All such shares (and Other Securities) shall be duly authorized and, when issued
upon such exercise, shall be validly issued, fully paid and non-assessable and
free and clear of all preemptive rights.

     3.   Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issuable upon the exercise of these Warrants, but
the Company shall pay the Holder an amount equal to the fair market value of
such fractional shares in lieu of each fraction of a share otherwise issuable
upon any exercise of these Warrants, as determined by the Board of Directors in
its reasonable discretion.

     4.   Exchange of Warrants. These Warrants are exchangeable, without
expense, at the option of the Holder, upon presentation and surrender hereof to
the Company or at the office of its stock transfer agent, if any, for other
Warrants of different denominations, entitling the Holder to purchase in the
aggregate the same number of shares of Warrant Stock (and Other Securities)
purchasable hereunder.

     5.   Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights as a shareholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed herein.

     6.   Anti-Dilution Provisions.

     6.1  Adjustment for Recapitalization. If the Company shall at any time
subdivide its outstanding shares of Common Stock (or Other Securities at the
time receivable upon the exercise of these Warrants) by recapitalization,
reclassification or split-up thereof, or if the Company shall declare a stock
dividend or distribute shares of Common Stock to its shareholders, the number
of shares of Common Stock (or Other Securities) subject to these Warrants
immediately prior to such subdivision shall be proportionately increased and the
Exercise Price per share shall be proportionately decreased, and if the Company
shall at any time combine the outstanding shares of Common Stock (or Other
Securities) by recapitalization, reclassification or combination thereof, the
number of shares of Common Stock (or Other Securities) subject to these
Warrants immediately prior to such combination shall be proportionately
decreased and the Exercise Price per share shall be proportionately increased.
Any such adjustments pursuant to this Section 6.1 shall be effective at the
close of business on the effective date of such subdivision or combination or,
if any adjustment is the result of a stock dividend or distribution, then the
effective date for such adjustments shall be the record date therefor.

     6.2  Adjustment for Reorganization, Consolidation, Merger, Etc. (a) In case
of any reorganization of the Company (or any other corporation, the securities
of which are at the time receivable upon the exercise of these Warrants) after
the date hereof or in case after such date the Company (or any such other
corporation) shall consolidate with or merge into another corporation or convey
all or substantially all of its assets to another corporation, then, and in each
such case, the Holder, upon the exercise hereof, at any time after the
consummation of such reorganization, consolidation, merger or conveyance, shall
be entitled to receive, in lieu of the securities and property receivable upon
the exercise of these Warrants prior to such consummation, the securities or
property to which the Holder would have been entitled upon such consummation if
the Holder had exercised these Warrants immediately prior thereto (but had not
exercised any rights with respect to such securities or property in connection
with the reorganization, consolidation, merger or conveyance); in each such
case, the terms of these Warrants shall be applicable to the securities or
property receivable upon the exercise of these Warrants after such consummation.

     (b)  In any case where the Company shall consolidate with or merge into
another corporation, and shall not be the surviving corporation, or shall
convey all or substantially all of its assets to another corporation, then, and
in each such case, the Company shall, as a condition of the closing of such
transaction, require that the surviving corporation or the corporation that
shall have received substantially all of the Company's assets expressly assume
the obligations of the Company under these Warrants in a form reasonably
satisfactory to the Holder.

     6.3  No Impairment. The Company will not, by amendment of its charter or
through reorganization, consolidation, merger, dissolution, issue or sale of
securities, sale of assets or any other voluntary action, willfully avoid or
seek to avoid the observance or performance of any of the terms of these
Warrants, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Holder against impairment.
Without limiting the generality of the foregoing, while these Warrants are
outstanding, the Company (a) will not permit the par value, if any, of these
shares of Warrant Stock to be above the amount payable therefor upon such
exercise and (b) will take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue or sell fully paid and
non-assessable shares of Warrant Stock and Other Securities upon the exercise
of these Warrants.

     6.4  Certificate as to Adjustments. In each case of an adjustment in the
number of shares of Warrant Stock or Other Securities receivable upon the
exercise of these Warrants, the Company at its expense will promptly compute
such adjustment in accordance with the terms of these Warrants and prepare a
certificate executed by an executive officer of the Company setting forth such
adjustment and showing in detail the facts upon which such adjustment is based.
The Company will forthwith mail a copy of each such certificate to the Holder.

     6.5  Notices of Record Date, Etc. In case:

     (a)  the Company shall take a record of the holders of its Common Stock
(or Other Securities at the time receivable upon the exercise of these
Warrants) for the purpose of entitling them to receive any dividend (other than
a cash dividend at the same rate as the rate of the last cash dividend
theretofore paid) or other distribution, or any right to subscribe for,
purchase, or otherwise acquire any shares of stock of any class or any other
securities, or to receive any other right; or

     (b)  of any capital reorganization of the Company, any reclassification of
the capital stock of the Company, any consolidation or merger of the Company
with or into another corporation, or any conveyance of all or substantially all
of the assets of the Company to another corporation; or

     (c)  of any voluntary or involuntary dissolution, liquidation or winding
up of the Company;


                                      - 3 -
<PAGE>   4
then, and in each such case, the Company shall mail or cause to be mailed to
the Holder a notice specifying, as the case may be, (i) the date on which a
record is to be taken for the purpose of such dividend, distribution or right,
and stating the amount and character of such dividend, distribution or right,
or (ii) the date on which such reorganization, reclassification, consolidation,
merger, conveyance, dissolution, liquidation or winding up is to take place,
and the time, if any, to be fixed, as to which the holders of record of Warrant
Stock (or such other securities at the time receivable upon the exercise of
these Warrants) shall be entitled to exchange their shares of Warrant Stock (or
such other securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding up. Such notice shall be mailed at least 
20 days prior to the date therein specified and these Warrants may be exercised
prior to said date during the term of these Warrants.

     8.   Restrictions on Transfer of Warrants, Stock and Other Securities. The
Warrant Stock and Other Securities may not be sold, transferred or otherwise
disposed of unless registered under the Securities Act of 1933 (the "Securities
Act") and any applicable state securities laws or pursuant to available
exemptions from such registration, provided that the seller delivers to the
Company an opinion of counsel satisfactory to the Company confirming the
availability of such exemption.

     9.   Legend. Unless the shares of Warrant Stock or Other Securities have
been registered under the Securities Act, upon exercise of any of these
Warrants and the issuance of any of the shares of Warrant Stock or Other
Securities, all certificates representing such securities shall bear on the
face thereof substantially the following legend:

     THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
     (THE "SECURITIES ACT") OR UNDER APPLICABLE STATE SECURITIES LAWS AND MAY 
     NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER 
     THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO
     AVAILABLE EXEMPTIONS FROM SUCH REGISTRATION, PROVIDED THAT THE SELLER 
     DELIVERS TO THE COMPANY AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY 
     CONFIRMING THE AVAILABILITY OF SUCH EXEMPTION.

     10.  No Rights or Liabilities as Shareholder. This Warrant does not by
itself entitle the Holder to any voting rights or other rights as a shareholder
of the Company. In the absence of affirmative action by the Holder to purchase
Warrant Stock by exercise of this Warrant, no provisions of this Warrant, and
no enumeration herein of the rights or privileges of the Holder shall cause the
Holder to be a stockholder of the Company for any purpose.

     11.  Amendment; Waiver. Any term of the Warrants may be amended and the
observance of any term of the Warrants may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holder. Any amendment or waiver effected
in accordance with this Section shall be binding upon the Holder and the
Company.

     12.  Notices. All notices required hereunder shall be in writing and shall
be deemed given when telegraphed, delivered personally or within two days after
mailing when mailed by certified or registered mail, return receipt requested,
to the Company at its principal office, or to the Holder at the address set
forth on the record books of the Company, or at such other address of which the
Company or the Holder has been advised by notice in writing hereunder.


                                      - 4 -
<PAGE>   5
     13.  Assignment. These Warrants, and the rights of the Holder hereunder,
are not assignable by the Holder, except to a CBS Assignee (as defined in the
Principal Agreement). Any attempted assignment in violation of this Section 13
shall be null and void.

     14.  Applicable Law. These Warrants shall be governed by, and construed in
accordance with, the laws of the State of Delaware, without giving effect to
conflicts of law principles.

     IN WITNESS WHEREOF, the Company has caused these Warrants to be signed on
its behalf, in its corporate name, by its duly authorized officer, all as of
the day and year first above written.

Dear Sean and Derek:

     Reference is made to the Warrants dated March 5, 1997 ("Warrants"), issued
by SportsLine USA, Inc. ("SportsLine") to CBS Inc. ("CBS"). As of the date
hereof, the Warrants represent the right to purchase 380,000 shares of
SportsLine common stock at an exercise price of $10.00 per share.

     This is to confirm our agreement that the time prior to which the Warrants
may be exercised shall be extended until 5:00 p.m., Fort Lauderdale time on

31, 1997, the Warrants may only be exercised in whole, and not in part. Until
the Extended Expiration Time, and except as amended by this letter agreement,
all of the other terms and conditions of the Warrants shall remain in full force
and effect in accordance with their terms. At the Extended Expiration Time,
unless exercised in accordance with their terms, the Warrants shall expire and
be null and void and of no further force and effect.

     Please acknowledge your agreement to the foregoing by signing below where
indicated.

                                                       Very truly yours,
