                            CONTENT LICENSE AGREEMENT

                  THIS CONTENT LICENSE AGREEMENT (THE "AGREEMENT"), dated as of
26, 2000 (the "Effective Date"), by and between HEALTHEON/WEBMD CORPORATION, a
Delaware corporation ("WebMD"), and THE NEWS CORPORATION LIMITED a South
Australia, Australia corporation (the "Company").


                              W I T N E S S E T H:

                  WHEREAS, WebMD owns and operates a Web Site on the World Wide
Web currently accessible through the URL www.webmd.com which displays health and
medical content intended for consumers and healthcare professionals and
provides, promotes and sells healthcare related information, services and
products to consumers and healthcare professionals (the "WebMD Site"); and

                  WHEREAS, WebMD owns or licenses the WebMD Content which WebMD
uses in connection with the development and operation of the WebMD Site; and

                  WHEREAS, pursuant to a Master Strategic Alliance Agreement
dated December 6, 1999, by and between WebMD and the Company (the "Strategic
Alliance Agreement") WebMD desires to license to the Company the right to use
the WebMD Content for the purpose of using, displaying and publishing the WebMD
Content in any television, print, electronic or other medium now know or
hereinafter developed, owned or operated by the Company and/or its Operating
Companies (other than a Web Site) (individually a "News Channel" and
collectively the "News Channels").

                  NOW, THEREFORE, in consideration of the foregoing premises and
the agreements and covenants herein set forth and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties do hereby agree as follows:

                                    ARTICLE 1

                                   DEFINITIONS

         All capitalized terms used in this Agreement without definition shall
have the meanings ascribed to such terms in Exhibit A.

                                    ARTICLE 2

                        CREATION OF LICENSE RELATIONSHIP

         2.1      GRANT OF LICENSE. Except as may be prohibited or otherwise
limited by the terms of any other obligations binding on the WebMD Group, other
than obligations that were incurred with the primary intent to frustrate the
purpose of this Agreement, and subject to terms and conditions of this
Agreement, WebMD for itself and on behalf of the other members of the WebMD
Group hereby agrees to provide, to cause Controlled Affiliates to provide, and
to use commercially reasonable efforts to cause Non-Controlled Affiliates to
provide, to the Company a non-exclusive license (the "License") during the term
hereof throughout the Territory to:

                  (a)      use, copy, translate, display, publish and transmit
         the WebMD Content solely for the purpose of developing and operating
         the News Channels; and

                  (b)      subject at all times to the obligations and duties of
         the Company contained herein, sublicense only to Operating Companies
         the rights granted hereunder; provided, however, that the Company shall
         (i) obtain WebMD's prior written consent to each such sublicense (other
         than with respect to Operating Companies directly or indirectly wholly
         owned by the Company); (ii) obtain from such Operating Companies a
         written instrument approved as to form and substance by WebMD, pursuant
         to which each such Operating Company shall agree to be bound and comply
         with the terms of this Agreement and (iii) at all times remain fully
         liable for the actions of its Operating Companies. Operating Companies
         with respect to which the foregoing conditions have been satisfied
         shall hereinafter be referred to as "Sublicensees." The Sublicensees
         shall be prohibited from granting any further sublicenses of the rights
         granted hereunder to any other Person without the express prior written
         approval of WebMD. WebMD agrees that any consent or approval required
         by it under this Section 2.1(b) will not be unreasonably denied or
         delayed and that WebMD will cooperate with the Company in completing
         any approval process required hereunder in a reasonably expeditious
         manner given the facts and circumstances pertaining to such approval.

         As used herein, "Controlled Affiliates" means any corporation or other
entity more than 50% of whose outstanding voting securities or other equity
interest are directly or indirectly owned by WebMD; "Non-Controlled Affiliates"
means any corporation or other entity in which WebMD directly or indirectly has
a greater than 20% but no more than 50% equity interest.

         2.2      SCOPE OF LICENSE; RESTRICTIONS ON USE OF WEBMD CONTENT.

                  (a)      The License granted hereunder is non-exclusive and
         the Company agrees to use the WebMD Content in accordance with the
         terms hereof and solely for the purpose of engaging in the Licensed
         Activities. The Company acknowledges that the grant of rights hereunder
         excludes the right to use the WebMD Content in connection with (i) the
         development or operation of any Web Site similar to the WebMD Site or
         the development or operation of any Web Site which is otherwise
         targeted or marketed primarily to health professionals anywhere in the
         world; or (ii) the development or

<PAGE>   6

         operation of any Web Site which is intended to display directly or
         indirectly (through links or otherwise) health or medical content as a
         distinct feature, section or subject matter anywhere in the world or
         (iii) use the WebMD Content in connection with any Web Site described
         (i) or (ii) above. The parties hereto agree that the covenants and
         agreements set forth in this Section 2.2(a) are in addition to the
         restrictive covenants set forth in Section 10.1 of the Strategic
         Alliance Agreement. Additionally, the Company acknowledges that any
         sublicense of the rights granted hereunder shall be strictly limited in
         accordance with the terms hereof.

                  (b)      The Company acknowledges and agrees that the scope of
         the License granted hereunder is limited by and is subject to any and
         all of WebMD's preexisting obligations, other than obligations that
         were incurred with the primary intent to frustrate the purpose of this
         Agreement. Accordingly, the Company agrees to conduct the activities
         hereunder in accordance with all such limitations or restrictions which
         may exist of which the Company has received written notice.

                  (c)      Notwithstanding anything to the contrary contained in
         this Agreement, WebMD shall have no obligation whatsoever to license to
         the Company, or to authorize the Company to sublicense any of the
         rights granted hereunder with respect to any particular country unless
         and until WebMD shall determine, in the exercise of its reasonable
         discretion, that (i) such country's laws afford adequate protection of
         WebMD's interests in or ownership of the WebMD Content, WebMD Property
         and WebMD Logos (collectively the "WebMD Intellectual Property"), and
         (ii) the use of the WebMD Intellectual Property (or any part thereof)
         in such country will not violate any Requirement of Law or expose WebMD
         or any of its Affiliates to any unreasonable risk or liability which
         might arise as a result of the use or display of any of the WebMD
         Intellectual Property in such country. In its exercise of its
         reasonable discretion under this Section 2.2(c), WebMD shall have the
         right to request from the Company or a Sublicensee an opinion of
         counsel or such other information to WebMD's reasonable satisfaction
         opining about or providing such other information on a Requirement of
         Law or such other matters relating to the protection of WebMD's
         interests as WebMD may request, such opinion or information to be
         obtained at the Company's or such Sublicensee's expense. WebMD agrees
         to exercise its rights in the preceding sentence in a reasonable manner
         so as to avoid unnecessary delays or interruptions in the business of
         the Company and the Sublicensees.

         2.3      GRANT OF RIGHT IN WEBMD LOGO

                  (a)      WebMD Logo. WebMD hereby grants the Company a limited
         non-exclusive license to use the WebMD logo in the form appearing in
         Exhibit B attached hereto and any other WebMD marks, logotypes, or
         brand identifiers as WebMD may provide to the Company from time to time
         (collectively, the "WebMD Logo") during the Term of this Agreement.
         Such license is granted solely in connection with the Company's rights
         and obligations under this Agreement. All such uses will be in
         compliance with WebMD's written trademark guidelines as provided by
         WebMD to the Company from time to time. The Company will also be
         allowed to use and reproduce the WebMD Logo for the promotion of the
         WebMD Content, although to the extent such

<PAGE>   7

         promotions involve media placements outside of the News Channels, then
         the Company will only be allowed to make such uses and reproductions as
         WebMD may approve in writing in advance of such promotion or
         promotions.

                  (b)      Limitations. The Company agrees that it will not in
         any way suggest or imply by the use of the WebMD Logo that the News
         Channels or any of their respective products or services are affiliated
         with, endorsed or sponsored by or created in association with WebMD
         except as agreed by WebMD. The Company acknowledges that WebMD owns all
         right, title and interest and to the WebMD Logo and retains all rights
         with respect thereto. The Company agrees not to do anything
         inconsistent with such ownership and all uses of the WebMD Logo will
         inure to the benefit of and on behalf of WebMD. The Company further
         agrees that it will not attack or assist others in attacking the title
         of the WebMD Logo.

                  (c)      No Violation.  The Company acknowledges and agrees
         that:

                           (i)      it will not register any WebMD Logo;

                           (ii)     it will not knowingly permit any third party
                  to use any WebMD Logo unless authorized to do so in writing by
                  WebMD in this Agreement or otherwise;

                           (iii)    it will not knowingly use or permit the use
                  of any mark, name, or image likely to cause confusion with any
                  WebMD Logo other than the WebMD Logo itself unless authorized
                  to do so in writing by WebMD; and

                           (iv)     all goodwill associated with the Company's
                  use of the WebMD Logos will inure to WebMD.

                  (d)      Prior Approval. The manner and form of use of the
         WebMD Logos will be subject to WebMD's prior written approval, which
         approval will not be unreasonably withheld or delayed following its
         receipt of a sample, mock-up or other suitable example which provides
         a fair representation of the proposed use of the WebMD Logo concerned
         and indicates the context in which the WebMD Logo is to be used. Once
         a use of a WebMD Logo is approved for use under certain
         circumstances, then it is agreed that the Company may subsequently
         make substantially similar uses of the WebMD Logo under similar
         circumstances, but only until WebMD revokes or limits its approval
         which it may do at its sole discretion. The Company will conform to
         any alteration or revocation of the approval as soon as is
         commercially reasonable.

         The license granted pursuant to this Section 2.3 may be terminated
by WebMD upon a material breach by the Company, or any Affiliate of the
Company or any Sublicensee, of any material agreement, covenant or obligation
under this Section 2.3, which breach, if curable, remains uncured for a period
of sixty (60) days following the Company's receipt of written notice from
WebMD of the existence of such breach.

<PAGE>   8

         2.4      NO OTHER RIGHTS GRANTED. Apart from the rights licensed under
Sections 2.1 and 2.3 above, this Agreement does not grant to the Company any
right to engage in any activity other than the Licensed Activities, nor any
ownership right, title, or interest, nor any security interest or other
interest, in any of the WebMD Intellectual Property or any proprietary rights
relating to or created from such WebMD Intellectual Property or any developments
or enhancements with respect thereto.

         2.5      ROYALTY. In consideration of WebMD's commitments set forth
herein, the Company will, in addition to its other commitments hereunder, pay to
WebMD during the Initial Term an annual royalty of twelve million U.S. dollars
($12,000,000), which amount shall be payable annually in advance in four equal
quarterly installments, which shall be paid at the commencement of each
quarterly period beginning on the date hereof and on each April 1, July 1,
October 1 and January 1 thereafter.

                                    ARTICLE 3

                                  WEBMD CONTENT

                  3.1      SELECTION, FORMAT, DESIGN AND UPDATING.

                  (a)      WebMD may from time to time, modify and update the
         WebMD Content as such modifications and/or updates are deemed necessary
         or desirable by WebMD and the Company shall (to the extent that
         particular WebMD Content is used by the Company) use such WebMD content
         as modified or updated.

                  (b)      With respect to any content WebMD obtains for use on
         the WebMD Site, WebMD shall use reasonable commercial efforts to secure
         the approval of third parties for the use by the Company of such
         content. WebMD shall not be required to incur any additional cost in
         securing such approval; provided, however, that in the event approval
         to use such content may only be obtained by payment of any fee by
         WebMD, WebMD, WebMD shall incur such cost only at the Company's request
         and the Company shall have the obligation to reimburse WebMD for such
         cost.

                  (c)      With respect to the WebMD Content licensed hereunder,
         the Company shall have the right to determine, in its reasonable
         discretion, the WebMD Content it selects to display and/or publish on
         the News Channels at any time, and from time to time subject to the
         other provisions hereof; provided, however, that the Company shall
         clearly attribute all WebMD Content used on a News Channel to WebMD.
         Except as may be authorized in advance in writing by WebMD, or for the
         purpose of localizing the WebMD Content, the Company shall have no
         right to substantively modify in any manner whatsoever, any of the
         WebMD Content licensed hereunder. WebMD Content which is owned or
         controlled by a third party shall incorporate such credit designated by
         such third party or WebMD and the Company and Sublicensees shall
         preserve all such attributional rights.

         3.2      REMOVAL OF WEBMD CONTENT. WebMD may, for good reason, from
time to time require the removal of any WebMD Content from any News Channel. If
WebMD requests removal of certain WebMD Content from a News Channel, the Company
shall complete such

<PAGE>   9

removal on the earlier of (i) the first commercially practicable date on which
the Company could terminate distribution of such programming or (ii) five
business days following receipt of WebMD's request for such removal.

         3.3      OWNERSHIP OF WEBMD CONTENT; WEBMD PROPERTY. WebMD shall at all
times remain the owner of all right, title and interest in and to the WebMD
Content or any parts or derivatives thereof or any variations thereon. WebMD
shall own all right, title and interest in all aspects of the Look and Feel,
images and all other content, regardless of whether it is capable of trademark,
patent or other intellectual property law protection, furnished by or on behalf
of WebMD to the Company or the Sublicensees and displayed on the News Channels
or any parts or derivatives thereof or any variations thereon (collectively, the
"WebMD Property").

         3.4      USER INFORMATION. All data regarding any user of the WebMD
Site, their personal information, or information regarding their use of or
interaction with the WebMD Site shall at all times be and remain the sole and
exclusive property of WebMD ("WebMD User Information").

         3.5      OTHER AGREEMENTS. The Company:

                  (a)      agrees to comply with all Requirements of Law in
         connection with the use of the WebMD Content;

                  (b)      agrees that all rights in and to any of the WebMD
         Content not expressly licensed hereunder are reserved to WebMD;

                  (c)      agrees not to sublicense, assign, transfer, pledge,
         offer as security, or otherwise encumber the WebMD Content or any of
         the rights granted hereunder in any way other than as expressly
         provided in the Agreement;

                  (d)      agrees not to use any of the WebMD Content in any
         manner or for any purpose whatsoever in violation of the terms of this
         Agreement;

                  (e)      acknowledges and agrees that it shall not at any time

                         REPRESENTATIONS AND WARRANTIES


         4.1 REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY AND WEBMD.

                  (a)      Authority of the Company. The Company agrees and
         represents that the Company has the authority to execute, deliver and
         perform its obligations under this Agreement, having obtained all
         required consents, and is duly organized or formed and validly existing
         in good standing under the laws of the state of its incorporation or
         formation.

                  (b)      Conflicts. The Company acknowledges that WebMD has
         licensed the WebMD Content to other parties to promote and enhance the
         goodwill of the WebMD Content. The Company agrees that in the event
         WebMD determines that the Company's activities taken pursuant to this
         Agreement come into conflict with the interests or rights of other
         licensees, the Company shall in good faith cooperate with WebMD in
         order to resolve the conflict and, in the event the conflict cannot be
         resolved, shall take the action requested by WebMD as long as it is
         commercially practical to do so; provided, however, that WebMD
         represents and warrants that there are no such licenses which might
         reasonably be expected to have a material adverse effect on the
         Company.

                  (c)      Authority of WebMD. WebMD represents and warrants
         that WebMD has (i) the authority to execute, deliver and perform its
         obligations under this Agreement, having obtained all required Board of
         Directors or other consents, (ii) is duly organized or formed and
         validly existing in good standing under the laws of the state of its
         incorporation or formation and (iii) owns all right, title and interest
         in and to the WebMD Content authored by WebMD and has all rights
         necessary to license the third party content provided to the Company
         hereunder. The parties agree that the Company's or any Sublicensee's
         remedy with respect to a breach of WebMD's representation set forth in
         Section 4.1(c) above shall be as set forth in Section 6.1(b) herein.

                  (d)      EXCEPT FOR THE EXPRESS WARRANTIES STATED HEREIN,
         WEBMD DOES NOT MAKE ANY WARRANTY AS TO THE ACCURACY OF ANY WEBMD
         CONTENT LICENSED HEREUNDER OR THE RESULTS TO BE OBTAINED FROM ANY NEWS
         CHANNEL USING THE WEBMD CONTENT. EXCEPT FOR THE EXPRESS WARRANTIES SET
         FORTH ABOVE, THE WEBMD CONTENT IS USED ON AN "AS-IS" BASIS WITHOUT
         WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT
         LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
         PURPOSE, OR NON-INFRINGEMENT.

may be extended for a period of five (5) years from and after the Initial Term

         covenant or obligation hereunder, which breach, if curable, remains
         uncured for a period of sixty (60) days following the Company's receipt
         of written notice from WebMD of the existence of such breach.

                  (d)      Upon the exercise by the News Member (as defined in

         Agreement.

         5.3      RIGHT TO TERMINATE BY THE COMPANY

         5.4      EFFECT OF TERMINATION.  Upon the expiration or termination of
the Term:

                  (a)      the License will automatically terminate;

                  (b)      the Company shall and shall cause all Sublicensees to
         immediately cease to use, display, reproduce, sublicense, transmit
         and/or distribute in any manner and for any purpose, directly or

<PAGE>   12

                  (c)      the Company shall and shall cause all Sublicensees to

                  (d)      in the event of termination by the Company pursuant
         to 5.3(c) (material breach by WebMD), WebMD shall promptly pay the

4, 6 and 7, Section 2.5 and 5.4(d), and this Section 5.5, and each party hereto
shall be, and shall continue to be and remain liable to the other parties for
any and all damages which such party has or may sustain by reason of such first
party's default or breach of such provisions of this Agreement.

                                    ARTICLE 6

                                 INDEMNIFICATION

         6.1      AGREEMENT OF WEBMD TO INDEMNIFY. (a) Except as set forth in
         Section 6.1(b) below and subject to the limitation of liability set
         forth in Section 6.4 hereof, WebMD hereby agrees to indemnify, defend
         and hold harmless the Company and its directors, officers, employees
         and agents and their respective successors and assigns (collectively
         the "Company Indemnitees") from and against any loss, costs, expenses
         (including reasonable attorneys' fees and expenses), claims, demands,
         liabilities, causes of action or damages incurred by any Company
         Indemnitee in connection with or relating to any material breach of a
         representation, warranty, covenant or agreement of WebMD contained in
         this Agreement.

                  (b)      The parties hereto agree that with respect to any
         claim that the Company or any Sublicensee infringes any copyright or
         trademark or other intellectual property

<PAGE>   13

         right as a result of the Company's (or a Sublicensee's) use or display
         of the WebMD Content, WebMD will only be responsible for the payment of
         any judgment, fine and/or penalty finally awarded against the Company
         or such Sublicensee as a result of such claim and any settlements
         agreed to with respect to such claim.

                  6.2      AGREEMENT OF THE COMPANY TO INDEMNIFY. Subject to the
         limitation of liability set forth in Section 6.4 hereof, the Company
         hereby agrees to indemnify, defend and hold harmless WebMD and its
         officers, directors, shareholders, employees, agents and Affiliates and
         their respective successors and assigns (collectively the "WebMD
         Indemnitees") from and against any loss, costs, expenses (including
         reasonable attorneys' fees and expenses), claims, demands, liabilities,
         causes of action or damages incurred by any WebMD Indemnitee in
         connection with or relating to any material breach of a representation,
         warranty, covenant or agreement contained in this Agreement by the
         Company, its Affiliates, the Sublicensees or any of their respective
         officers, directors, employees or agents.

                  6.3      THIRD PARTY CLAIMS. A Person entitled to
indemnification for a Claim hereunder (the "Indemnified Party") shall give the
indemnifying party with respect to such Claim (the "Indemnifying Party")
reasonably prompt notice of such Claim brought by a third party. Such notice
shall describe the Claim in reasonable detail. The failure of the Indemnified
Party to give such notice to the Indemnifying Party shall not impair any of the
Indemnified Party's rights or benefits under this Article 6 except to the extent
such failure adversely affects the Indemnifying Party's ability to defend such
Claim. The Indemnifying Party, within a reasonable time after receiving
knowledge of a Claim by a third party against the Indemnified Party, shall (a)
notify the Indemnified Party in writing of the preference of the Indemnifying
Party to assume the defense thereof, and (b) retain legal counsel reasonably
acceptable to the Indemnifying Party to conduct the defense of such Claim. The
Indemnified Party shall cooperate with the Indemnifying Party in any manner
reasonably requested in connection with the defense, compromise or settlement of
any Claim. In any such Claim which the Indemnifying Party chooses to defend, the
Indemnified Party shall have the right to engage separate counsel and to
participate in the prosecution, defense, compromise, or settlement thereof or to
conduct its own defense of such claim. The fees and expenses of such counsel
engaged by the Indemnified Party (if the Indemnifying Party is conducting its
defense) shall be at the expense of the Indemnified Party unless the named
parties to any such Claim (including any impleaded parties) include the
Indemnified Party and the Indemnifying Party, and the Indemnified Party shall
have been advised by its counsel that there is a conflict of interest between
the Indemnified Party and the Indemnifying Party in the conduct of the defense
thereof. In such case, the reasonable fees and expenses of such separate counsel
to the Indemnified Party shall be borne by the Indemnifying Party. The
Indemnifying Party shall not, without written consent of the Indemnified Party,
compromise, settle or consent to entry of any order or judgment with respect to
any Claim (i) which involves any relief other than the payment of money damages
against the Indemnified Party or (ii) which does not include as an unconditional
term thereof, the giving by the defendant or Person conducting such
investigation or initiating such hearing, to the Indemnified Party, of a release
from all liability with respect to such Claim and all other Claims or causes of
action (known or unknown) arising or which might arise out of the same facts.

PROFITS, BUSINESS INTERRUPTION, LOSS OF BUSINESS INFORMATION AND THE LIKE, EVEN
IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Company shall not disclose any Proprietary Information to any Person, except (a)
with the prior written consent of WebMD; (b) to the extent necessary to comply

to the extent such information: (i) is already known to the Company at the time

that, notwithstanding Section 7.2 above, this Agreement, or portions hereof, may
be required under applicable law to be disclosed as part of or an exhibit to a
party's required public disclosure documents. If either party is advised by its
legal counsel that such disclosure is required, it will notify the other party

         7.7      BINDING EFFECT; SUCCESSORS AND ASSIGNS; ENTIRE AGREEMENT.
Except as expressly provided in this Agreement, nothing in this Agreement,
express or implied, is intended or shall be construed to confer upon or give any
Person (including creditors and Affiliates of any party) other than the parties
hereto any remedy or claim under or by reason of this Agreement or

<PAGE>   17

any term, covenant or condition hereof, all of which shall be for the sole and
exclusive benefit of the parties. This Agreement and all of the provisions
hereof shall be binding upon and inure to the benefit of the parties and their
respective successors, legal representatives and permitted assigns; provided,
however, that, except as otherwise specifically permitted by this Agreement,
neither this Agreement nor any of the rights, interests or obligations of the
Company or WebMD hereunder shall be assigned or delegated without the prior
written consent of the other party. This Agreement sets forth the entire
agreement and understanding among the parties hereto as to the subject matter
hereof.

         7.8      AMENDMENTS AND WAIVERS. This Agreement may not be amended,
modified or supplemented unless approved in writing by each party to this
Agreement. No waiver of any right or remedy or of compliance with any provisions
hereof, and no consent provided for herein, shall be effective unless evidenced
by an instrument in writing executed by the party sought to be charged with such
waiver or consent. The rights and remedies herein expressly provided are
cumulative and not exclusive of any other rights or remedies which any party
hereto would otherwise have at law, in equity, by statute or otherwise.

         7.9      HEADINGS. The headings of the Sections contained in this
Agreement are solely for convenience of reference, are not part of the agreement
of the parties and shall not affect the meaning or interpretation of this
Agreement.

         7.10     NO IMPLIED WAIVERS. No action taken pursuant to this
Agreement, including, any investigation by or on behalf of any party, shall be
deemed to constitute a waiver by the party taking such action of compliance with
any representations, warranties, agreements, covenants, obligations or
commitments contained herein or made pursuant hereto. The waiver by any party of
a breach of any provision of this Agreement shall not operate or be construed as
a waiver of any preceding or succeeding breach and no failure by any party to
exercise any right, privilege or remedy hereunder shall be deemed a waiver of
such party's rights, privileges or remedies hereunder or shall be deemed a
waiver of such party's rights to exercise the same at any subsequent time or
times hereunder.

         7.11     COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original of the party or
parties executing the same and all of which together shall be deemed to
constitute one and the same agreement.

         7.12     FURTHER ASSURANCES. Each party shall cooperate and take such
actions as may be reasonably requested by another party in order to carry out
the provisions and purposes of this Agreement and the transactions contemplated
hereby.

         7.13     SEVERABILITY. If any provision of this Agreement or the
application thereof to any Person or circumstance is held by a court of
competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof, or the application of such provision to Persons or
circumstances other than those as to which it has been held invalid or
unenforceable, shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby; provided that, if any provision
hereof or the application thereof shall be so held to be invalid, void or
unenforceable by a final Judgment of a court of competent jurisdiction, then
such court may substitute therefor a suitable and equitable provision in order
to carry out, so far as may be

<PAGE>   18

valid and enforceable, the intent and purpose of the invalid, void or
unenforceable provision and if such court shall fail or decline to do so, the
parties shall negotiate in good faith a suitable and equitable substitute
provision. To the extent that any provision shall be judicially unenforceable in
any one or more states of the United States or in any foreign jurisdiction, such
provision shall not be affected with respect to any other state within the
United States or any other foreign jurisdiction, each provision with respect to
each state of the United States or foreign jurisdiction being construed as
several and independent.

         7.14     INJUNCTIVE RELIEF. Each party acknowledges that a breach or
threatened breach by it or any Sublicensee or Affiliate of this Agreement will
result in immediate and irremediable damage to the other party and that money
damages alone would be inadequate to compensate such other party. Therefore, in
the event of a breach or threatened breach of this Agreement by either of the
parties (or any Sublicensee or Affiliate), the other party may, in addition to
other remedies, immediately obtain and enforce injunctive relief prohibiting the
breach or threatened breach or compelling specific performance.

         7.15     NO PARTNERSHIP, ETC. Nothing contained herein shall be
construed as creating a joint venture, Company, agency, employment relationship
or other enterprise between the parties.

         7.16     CONSTRUCTION. The Company and WebMD have participated jointly
in the negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Company and WebMD and no presumption or burden of
proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

         7.17     DISCLAIMER OF WARRANTIES. The Company hereby acknowledges and
agrees that WebMD has made no promises, representations, guarantees or
warranties, of any nature, other than those which may be made expressly in this
Agreement.

         7.18     PLURALS. When necessary for appropriate meaning, a plural
shall be deemed to be the singular and singular shall be deemed to be the
plural.

         7.19     EFFECTIVENESS. The submission of this Agreement does not
constitute an offer to license and this Agreement shall become effective only
upon execution thereof by the Company and WebMD.
