2.       CBS ADVERTISING AND PROMOTION

         2.1 (a) CBS shall arrange for the placement of advertising and
promotion in the United States of the Consumer Health Site, the Professional
Health Site and Medscape's other 

                                     - 2 -

products and services in the media category or type set forth in the Advertising
and Promotion placement roster set forth on Exhibit A attached hereto, with an
aggregate value of $150 million. During the first Contract Year, CBS shall
arrange for the placement of advertising in accordance with the advertising plan
in Exhibit B attached hereto. CBS will consult with Medscape with respect to the
media category and type of placement. CBS and Medscape will cooperate to
endeavor to implement the advertising and promotional goals set forth in the
annual media plan presented to CBS by Medscape. The media plan for each Contract
Year shall be consistent with the media plans of prior Contract Years, except
that the advertising dollar amounts for the Contract Year concerned and the
allocation of advertisements during the contract year concerned shall be
mutually agreed upon by the parties. All advertising and promotional materials
shall be subject to the applicable CBS Network Advertising Guidelines and
standard CBS preemption policies. CBS shall not have to make any ad placements
if the exigencies of time or current or future contractual obligations entered
into prior to the time Medscape requests such advertising, prevent or restrict
CBS from doing so.

                  (b) The value of all broadcast advertising and promotion
provided hereunder shall be based upon the average unit price paid by any
unaffiliated third party, excluding barter, for spots (other than political
spots) purchased during the specific CBS Television Network, CBS Radio Network,
CBS Owned and Operated Television Station, CBS Owned and Operated Radio Station,
or CBS Cable broadcast in which the advertising or promotion occurs. The value
of banner advertising on CBS Internet sites shall be based upon the average
price paid (excluding barter) by unaffiliated third parties for banner
advertising of similar size and placement during a similar period. The value of
the Billboard Ad concerned shall be based upon the average price paid or
payable, excluding barter, for any similar Billboard Ad(s) during the month
prior to the month in which such Billboard Ad is delivered. Medscape will be
treated as a cash-paying customer in a like manner to other cash customers of
similar volume. The following advertisements shall not be offset against the
$150 million of advertising hereunder: any on-air mention or URL Scroll by a
CBS-affiliated (television or radio) station of the URL for the Consumer Health
Site, the New Mark URL or the Identifying URL (as such term is defined in the
Trademark and Content Agreement) on Medscape Programming (as such term is
defined in the Trademark and Content Agreement) obtained by such CBS-affiliated
station from the CBS Newspath feed or equivalent radio feed (other than a
broadcast of the CBS Radio Network). (For avoidance of doubt, "CBS-affiliated
station" is a television or radio station which is not owned and operated by
CBS.)

                  (c) CBS will provide to Medscape calendar quarterly
statements, or, if available, monthly statements showing the (i) value
attributable to each of the media categories and types with respect to the
advertising and promotions purchased by Medscape during the statement period and
(ii) the calculation of the aggregate value of advertising purchased.

         2.2 (a) CBS will maintain accurate books and records which report the
expenditure of the advertising and promotional value by Medscape and information
from which the calculation can be derived. Medscape may, at its own expense,
examine those books and records, as provided in this Section 2.2. Medscape may
make such an examination for a particular statement provided pursuant to Section
2.1(c) only once and such examination must occur within three (3) years after
the date such statement is sent by CBS to Medscape. (CBS will be deemed
conclusively to have sent Medscape the statement concerned at the time
prescribed in 



                                     - 3 -


Section 2.1(c), unless Medscape notifies CBS otherwise with respect to any
statement within thirty (30) days after that designated time.) Medscape may make
those examinations only during CBS's usual business hours, and at the address
set forth herein for the provision of notices to CBS, unless otherwise notified.
Medscape will be required to notify CBS at least ten (10) days before the date
of planned examination. If Medscape's examination has not been completed within
two (2) months from the time Medscape begins it, CBS may require Medscape to
terminate it on seven (7) days notice to Medscape at any time.

                  (b) If any examination of CBS's books and records discloses
         that:

                           (i) CBS has failed to properly account for
         advertising and promotions purchased by Medscape hereunder, then CBS
         will make appropriate adjustment(s) to the cumulative total purchased
         by Medscape.

                           (ii) CBS has overstated the value of advertising
         purchased by more than 7.5%, then CBS shall reimburse Medscape for its
         direct out-of-pocket expenses incurred in identifying such material
         overstatement.

         2.3      CBS shall have the right:

                  (a) to suspend and/or withdraw placement of all advertising
and promotion that includes the MEDSCAPE trademark: (i) pending resolution of
any third party claim covering infringement of such third party's rights because
of use by Medscape in the United States of the tradename or trademark "Medscape"
either alone or in combination with any other mark and/or (ii) during such time
as Medscape is enjoined from using the tradename or trademark "Medscape" in the
United States on or in connection with the Consumer Health Site and has not
renamed the Consumer Health Site. Medscape shall rename the Consumer Health Site
within thirty (30) days following the issuance of any injunction or the
resolution of any claim which requires Medscape to cease using the tradename or
trademark "Medscape" in the United States on or in connection with the Consumer
Health Site, it being understood, however, that CBS shall have the sole right
and power to approve the substitute tradename and/or trademark to be used. In
the event that CBS fails to approve the substitute tradename and/or trademark
within the thirty-day period, CBS shall submit a tradename proposal with three
(3) alternate tradenames which appear to be available for Medscape's use on the
Consumer Health Site in the United States based on trademark searches conducted
by CBS, for Medscape's approval, which approval is to be given within ten (10)
days of such submission. For avoidance of doubt, CBS does not and will not make
any representation or warranty with respect to the availability of any alternate
name provided to Medscape by CBS for use on the Consumer Health Site.
Medscape shall thereafter promptly apply for registration of such trademark.

                  (b) if the New Mark is being used as the principal name or
part of the principal name of the Consumer Health Site, to suspend and/or
withdraw placement of all the advertising and promotion of the Consumer Health
Site: (i) upon CBS's decision to cease use of the New Mark in connection with
any third party claim covering infringement of such third party's rights because
of use by Medscape in the United States of the New Mark either alone or in
combination with any other mark and/or (ii) during such time as Medscape is
enjoined from using the New Mark in the United States on or in connection with
the Consumer Health Site and has not renamed the Consumer Health Site. Medscape
shall rename the Consumer Health Site 

                                     - 4 -

CBS Medscape within ten (10) days following CBS's notice of its decision to
cease use of the New Mark, the issuance of any injunction or the resolution of
any claim which requires Medscape to cease using the New Mark in the United
States on or in connection with the Consumer Health Site. Upon Medscape's
renaming the Consumer Health Site, the placement of advertising for the Consumer
Health Site shall resume using the new name. Medscape will not seek (i)
reimbursement or payment for advertising and promotion time used or (ii) payment
of any of Medscape's conversion costs, in the event that CBS suspends and/or
withdraws placement of advertising and promotion of the Consumer Health Site
hereunder.

         2.4 CBS and Medscape shall mutually agree on (i) procedures to maximize
joint selling opportunities between Medscape's and CBS's respective ad sales
forces, and (ii) commissions payable with respect to such selling.

                           (ii) CBS's obligation to provide advertising and
         promotion to Medscape shall cease if:

                                    (A) CBS elects to pay Medscape the cash
                  equivalent of the difference, if any, between (x) One Hundred
                  and Fifty Million Dollars ($150,000,000) and (y) the amount of
                  promotional value provided to Medscape during the Term (the
                  "Shortfall"), subject to Section 6.4(b)(ii)(B) below.

                                    (B) provided CBS has not elected to pay
                  Medscape the Shortfall, then Medscape shall have the option,
                  exercisable on any anniversary of the Effective Date, to
                  require CBS to pay Medscape the applicable Shortfall, in lieu
                  of CBS's performing its advertising and promotion obligations,
                  if Medscape can show that CBS is unable to reasonably carry
                  out its obligation to provide advertising and promotion. CBS
                  will be deemed unable to carry out its obligation to provide
                  advertising and promotion if, at any time after termination of
                  this Agreement, CBS and Medscape fail to reach agreement on a
                  media plan for the Contract Year concerned (i.e., the period
                  which, but for termination, would have been the Contract Year
                  concerned) after good faith efforts by the parties to do so
                  (I) consistent with media plans executed or applicable in
                  prior Contract Years or (II) with respect to the first
                  Contract Year, consistent with the media plan agreed on or
                  executed by the parties and attached hereto as Exhibit B.

                                    (C) CBS shall pay the Shortfall as follows.

                                            (I) within thirty (30) days after
                           the end of each Contract Year remaining for (what
                           would have been) the balance of the Term, CBS shall
                           pay Medscape a cash payment, calculated on a pro-rata
                           basis for (what would have been) the balance of the
                           Term, equal to the difference between (x) the
                           promotional value which CBS would be, but for the
                           termination of this Agreement, obligated to provide
                           to Medscape pursuant to this Agreement for such
                           Contract Year; and (y) the amount of promotional
                           value actually provided to Medscape during such
                           Contract Year, if any; or

                                            (II) CBS may elect, at any time, to
                           pay the entire Shortfall amount to Medscape in a
                           lump-sum cash payment equal to the net present value
                           of the Shortfall, as follows:

                                                     (x) any Shortfall paid (at
                                    any time) during the first three years of
                                    the Term shall be calculated at the lower of
                                    (1) 

                                     - 9 -

                                    CBS's short-term debt financing rate or (2)
                                    CBS's average debt financing rate, during
                                    the prior twelve-month period;

                                                     (y) any Shortfall paid at
                                    any time after expiration of the third
                                    Contract Year shall be calculated at CBS's
                                    average debt financing rate during the prior
                                    twelve-month period.

                                            (III) All payments made pursuant to
                           this Section 6.4(b)(ii) shall be made in immediately
                           available, non-refundable funds wired to Medscape's
                           account in accordance with instructions to be
                           provided in writing by Medscape.

         6.5 (a) In the event of a material breach by CBS of this Agreement
(which gives rise to Medscape's right to terminate this Agreement), Medscape's
sole and exclusive remedy for such breach shall be the following: (i)
termination under Section 6.2; (ii) acceptance of CBS' payment, or promotion and
advertising, as applicable under Section 6.4; and (iii) termination of the
Trademark and Content Agreement and acceptance of payment of the sum of
$10,000,000 from CBS to Medscape, as liquidated damages and not as a penalty,
for loss by Medscape of the license under the Trademark and Content Agreement,
which shall be Medscape's sole and exclusive remedy under the Trademark and
Content Agreement. None of the foregoing remedies in this Section 6.5(a) may be
exercised by Medscape unless all are exercised by Medscape.

                  (b) Except as otherwise specified in Section 6.1(a)(ii) above,
in the event of a material breach by Medscape of this Agreement (which gives
rise to CBS's right to terminate this Agreement), CBS' sole and exclusive remedy
for such breach shall be: (i) termination of this Agreement under Section 6.1;
and (ii) to the extent that CBS so elects, termination of any Collaboration
Agreement.

         6.6 As between CBS and Medscape, Medscape agrees that under no
circumstances are the shares issued by CBS, under the Common Stock Purchase
Agreement, returnable to Medscape or subject to forfeiture. Medscape covenants
not to seek the return of the shares in any proceeding, between CBS, its
successors and assigns and Medscape, its successors and assigns.

         6.7 Except with respect to third party claims for which each partly
shall fully indemnify the other in accordance with the procedures set forth in
paragraph 5.1 above, neither party shall be liable to the other party for any
indirect, incidental, special, consequential, "business interruption" or any
loss of profits hereunder.


7.       CONFIDENTIALITY

         7.1 Medscape and CBS agree and acknowledge that they may be required to
disclose to each other certain confidential information, including but not
limited to information concerning the other party's online services and web
sites, technology, software, tools, business, or plans for the future in
connection with any of the foregoing, information concerning customers,
suppliers, personnel and other business relationships, sales and marketing
plans, financial information and other confidential information, all of which
shall be deemed 

                                     - 10 -

"Confidential Information" for the purposes of this Section if, with respect to
such information disclosed in tangible form, it is marked "Confidential" or its
equivalent, and if disclosed orally or visually, it is identified as
confidential at the time of disclosure.

         7.2 For a period of three (3) years from the date of receipt of any
Confidential Information hereunder, or in perpetuity with respect to source code
or related documentation, the receiving party agrees to protect the
confidentiality of the disclosing party's Confidential Information with at least
the same degree of care that it utilizes with respect to its own similar
proprietary information, but in no event less than a reasonable standard of
care, including without limitation agreeing:

                  (a) Not to disclose or otherwise permit any other person or
entity access to, in any manner, the Confidential Information, or any part
thereof in any form whatsoever, except that such disclosure or access shall be
permitted to (i) an employee or consultant of the receiving party requiring
access to the Confidential Information in the course of his or her employment or
consulting services in connection with this Agreement and who has agreed in
writing to maintain the confidentiality of the confidential information of third
parties in the receiving party's possession; or (ii) a director, legal advisor,
or financial advisor of the recipient party hereunder, provided that such
parties are bound to maintain the confidentiality of such information and
provided further that they are permitted to use such Confidential Information
only for the purposes of carrying out their fiduciary or other advisory
responsibilities on behalf of the party hereto from which it received such
Confidential Information; and

                  (b) Not to use the Confidential Information for any purpose
other than to carry out the purposes of this Agreement.

         7.3 Nothing in this Section 7 shall restrict the receiving party with
respect to information or data, whether or not identical or similar to that
contained in the Confidential Information, if such information or data: (i) was
rightfully possessed by the receiving party before it was received from the
disclosing party; (ii) is independently developed by the receiving party without
reference to the disclosing party's information or data; (iii) is subsequently
furnished to the receiving party by a third party not under any obligation of
confidentiality with respect to such information nor data, and without
restrictions on use or disclosure; or (iv) is or becomes public or available to
the general public otherwise than through any act or default of the receiving
party.

controlled by or under common control with, such party, or to any entity that
acquires such party by purchase of stock or by merger or otherwise, or by
obtaining substantially all of such party's assets (the "Permitted Assignee"),
provided that (i) no such assignment shall relieve the assigning party of any of
its

obligations under this Agreement; (ii) with respect to any assignments effected
by Medscape, no such Assignee (or any division thereof) is a CBS Competitor and

purposes of any suit, action or other proceeding arising out of this Agreement
or any transaction contemplated hereby or thereby. Each party hereto shall
commence any such action, suit or proceeding either in the United States
District Court for the Southern District of New York or if such suit, action or
other proceeding may not be brought in such court for jurisdictional reasons, in
the Supreme Court of the State of New York, New York County. Service of any
process, summons, notice or document by U.S. registered mail to a party's
address set forth below shall be effective service of process for any action,
suit or proceeding in New York with respect to any matters to which it has
submitted to jurisdiction in this Section 8.2. Each party hereto irrevocably and
unconditionally waives any objection to the laying of venue of any action, suit
or proceeding arising out of this Agreement or the transactions contemplated
hereby in (i) the Supreme Court of the State of New York, New York County; or
(ii) the United States District Court for the Southern District of New York, and

application of any such provision (or any portion thereof) to any Person or
circumstance shall be held invalid, illegal or unenforceable in any respect by a
court of competent jurisdiction, such invalidity, illegality or unenforceability
shall not affect any other provision hereof (or the remaining portion thereof)
or the application of such provision to any other Persons or circumstances, and
such provision will be limited or eliminated to the minimum extent necessary so
that this Agreement shall otherwise remain in full force and effect.

                               and Medscape, Inc.
          -------------------------------------------------------------


                                (Section 2.1(a))


CBS shall use commercially reasonable efforts to place $20 million of
advertising for Medscape during the first Contract Year. To the extent of any
shortfalls, such shortfalls will be placed by CBS during the following Contract
Year. CBS will make all commercially reasonable efforts to avoid a material
shortfall.

         CBS shall use commercially reasonable efforts to allocate the media
placement to allow for approximately sixty percent (60%) of the placements to
appear on network television; and the parties will mutually agree upon the
balance of the allocation. There may also be variances in the relative
allocations of up to ten percent (10%) for each category. All placements shall
be subject to the following:

         1.       The final decision on timing and placement will be at the sole
                  discretion of CBS;

         2.       CBS shall not be obligated to place any advertising on
                  Westwood One, Inc. media properties;

         3.       CBS shall not be obligated to place any advertising on the CBS
                  Radio Network, unless CBS either owns or controls the CBS
                  Radio Network.

         4.       In the event CBS divests itself of any of its media property
                  segments, CBS will use its commercially reasonable efforts to
                  have the acquirer of the media property segment concerned
                  honor the advertising placements or CBS will provide other
                  placements on other CBS media property segments of similar
                  value.

         5.       In the event CBS acquires new media property segments, CBS
                  will use its commercially reasonable efforts to have
                  Medscape's advertising placements extend to such new segments.

         6.       Except as set forth in Section 2.1 (b), all branding
                  references to the Consumer Health Site or mark during any CBS
                  News program, whether or not reference is made to the Consumer
                  Health Site URL, will count as advertising/promotion time,
                  consistent with CBS's treatment of its other Web Site
                  transactions.

         7.       In the event of any disputes, respecting the placement,
                  allocation or application of advertising under this Media
                  Plan, the parties' senior executives will first meet and work
                  in good faith to resolve such dispute, and if such dispute is
                  not resolved submit such dispute to a non-binding Alternative
                  Dispute Resolution ("ADR") 

                                     - 16 -

                  proceeding, with a nationally recognized ADR group such as
                  JAMS.
