                                     TERMS
                                     -----

1.   Development.
     -----------

     1.1.  Initial Specifications and Development. Company and AOL will, within
           --------------------------------------
           forty-five (45) days following the Effective Date, jointly agree in
           writing upon a development plan setting forth detailed specifications
           for the PMR Service to be developed by Company. Such development
           plan, as it may be amended from time to time by written agreement of
           both Parties, is referred to in this Agreement as the "Development
           Plan." The Development Plan will provide for the PMR Service to
           utilize AOL namespace and applicable elements and characteristics of
           that namespace (collectively the "AOL Namespace Technology"), so that
           all users of the PMR Service will be able to utilize AOL products,
           services, tools and utilities that utilize the AOL Namespace
           Technology. The Development Plan will also include the requirement
           that the PMR Service (a) conform with then-existing technologies
           identified by AOL which are optimized for the AOL Service and are
           compatible with AOL's then-available client and host software and the
           AOL Network; and (b) meet AOL's then current reasonable volume and
           performance requirements. The Development Plan will also include a
           commitment by Company to develop and maintain as part of the PMR
           Service an applications programming interface ("API") to facilitate
           the transmission and passage of data between AOL and Third Party
           Service Providers, which API shall be developed and maintained at a
           quality level consistent with industry APIs intended to facilitate
           electronic data interchange between commerce partners. Company's
           commitment to development and maintenance of the API pursuant to this
           Agreement does not extend to Backend servicing of Third Party Service
           Provider interfaces and connections to the API, which services the
           Parties understand Company may perform at a separate charge to such
           Third Party Service Providers.

     1.1   Timetable. The Parties will agree on a project timetable for
           ---------
           development and launch of the PMR Service as part of the Development
           Plan. Such project timetable, as it may be amended from time to time
           by written agreement of both Parties, is referred to in this
           Agreement as the "Project Timetable."

     1.2   Company Development Responsibilities. Company will be principally
           ------------------------------------
           responsible for the development of the PMR Service in accordance with
           this Agreement, including all technology and aspects thereof, such as
           user interface, database and database management technology and
           interface technology to interface the PMR Service to third parties
           and content and data from such third parties. Company agrees to
           diligently perform the development services and to develop and
           provide the PMR Service in accordance with the Development Plan, the
           Project Timetable
<PAGE>

           and the operating standards set forth in Exhibit "C" (the "Operating
           Standards"). Company will be responsible for devoting such personnel,
           equipment and resources as are required to accomplish such
           development.

     1.3   AOL Development Responsibilities. The Parties recognize that the
           --------------------------------
           Development Plan may provide for certain development tasks to be
           undertaken by AOL, where AOL has particular knowledge or expertise
           that would advance or facilitate such development. To the extent that
           the Development Plan provides that AOL is responsible for certain
           development tasks, AOL will diligently perform the development
           services for which it is responsible as set forth in the Development
           Plan, and AOL will be responsible for devoting such personnel,
           equipment and resources as are required to accomplish such
           development tasks in accordance with the Development Plan and the
           Project Timetable.

     1.4   Testing and Acceptance. The PMR Service shall, upon completion, be
           ----------------------
           subjected to such testing as each party may desire to conduct, and
           the PMR Service will not be deployed until approved by both Company
           and AOL. Upon completion of any such testing conducted by AOL, AOL
           shall provide Company written notice of approval or disapproval of
           the PMR Service. The Development Plan and/or Project Timetable shall
           set forth more detailed procedures, responsibilities and timetables
           for the acceptance testing process. Any disapproval by AOL shall be
           based upon AOL's determination that the PMR Service fails to conform
           to the Development Plan or is not suitable for commercial release and
           deployment. In the event of disapproval by AOL, AOL shall give its
           reasons for disapproval in reasonable detail, specifying the nature
           of the deficiencies, and Company shall thereafter use reasonable
           efforts to modify the PMR Service and resubmit it for further
           acceptance testing by AOL. This process shall continue until the PMR
           Service has been approved by AOL. The date on which AOL notifies
           Company that AOL approves the PMR Service is referred to herein as
           the "AOL Approval Date." Any subsequent enhancements, modifications
           or revisions to the PMR Service will also be subject to AOL's and
           Company's approval of the specifications therefor and AOL's and
           Company's testing and approval thereof as set forth in this Section
           1.5. No changes or additions will be made to the PMR Service until
           such changes or additions (a) conform with specifications agreed to
           by AOL, (b) conform with then-existing technologies identified by AOL
           which are optimized for the AOL Service and are compatible with AOL's
           then-available client and host software and the AOL Network; (c) meet
           AOL's then current reasonable volume and performance requirements;
           (d) meet such other requirements as AOL may reasonably require as a
           condition to acceptance of such changes or additions; and (e) have
           been accepted pursuant to this Section 1.5.

     1.2.  Additional Development Services.
           -------------------------------

           (a)   Requirements. At all times during the Term, Company will
                 undertake such development and make such changes to the PMR
                 Service as may be required to ensure that the PMR substantially
                 complies with the Operating Standards.

           (b)   Changes. After the initial development of the PMR Service,
                 -------
                 Company may make such changes to the PMR Service as Company
                 deems appropriate to maintain the PMR Service as a market-
                 competitive service, provided that such changes will be subject
                 to AOL's written approval, not to be unreasonably withheld. In
                 addition, Company will make such changes to the PMR Service as
                 AOL may reasonably request from time to time. Without limiting
                 the foregoing, Company will make such changes to the PMR
                 Service as AOL may reasonably request in order to implement
                 technological innovations as well as to integrate with the PMR
                 Services complementary products, services and/or technologies
                 designated by AOL that are provided by AOL or third parties,
                 including without limitation Third Party Service Providers. In
                 the event AOL requests that Company implement technological
                 innovations or complementary products, services and/or
                 technologies offered by an AOL Strategic Partner, Company will
                 undertake such changes using the technological innovations,
                 products, services and/or technologies offered by such third
                 party. In the event AOL requests that Company implement
                 technological innovations or complementary products, services
                 and/or technologies offered by a third party other than an AOL
                 Strategic Partner, Company may elect either to undertake such
                 changes using the technological innovations, products, services
                 and/or technologies offered by such third party or to deliver
                 to AOL within thirty (30) days following AOL's initial request
                 for such implementation a written plan for implementation of
                 alternative third party or Company technological innovations,
                 products, services and/or technologies offering comparable or
                 better functionality and performance, which plan shall be
                 subject to AOL's approval, not to be unreasonably withheld.
                 Company will provide development services under this Section
                 1.6(a)(ii) on a high priority basis and on at least as high a
                 priority basis as provided to any third party. Upon any request
                 by AOL for changes or any approval by AOL of changes proposed
                 by Company, the parties will agree upon the specifications for
                 such changes and a development schedule for such changes.

           (c)   Agreements with Third Party Service Providers. The Parties
                 ---------------------------------------------
                 recognize that a significant portion of the value of the PMR
                 Service is its ability to interface with products and services
                 offered by Third
<PAGE>

                 Party Service Providers. The Parties recognize that the
                 Development Plan may provide for certain development tasks to
                 be undertaken by third parties, where one or more third parties
                 has particular knowledge or expertise that would advance or
                 facilitate such development. If AOL reasonably requests that
                 Company integrate with the PMR Service complementary products,
                 services or technologies provided by an AOL Strategic Partner,
                 Company will negotiate in good faith with such third party and
                 will enter into, on commercially reasonable terms, such
                 agreements with such third party as may be required to
                 accomplish such integration. In the event that AOL obtains a
                 commitment from a Third Party Service Provider to integrate
                 with the PMR Service complementary products or services of such
                 Third Party Service Provider that are anticipated to expand the
                 number of consumers with access to the PMR Service, AOL may
                 require that Company co-brand or ingredient brand the PMR
                 Service with the name or logo of such Third Party Service
                 Provider in accordance with branding commitments negotiated by
                 AOL and such Third Party Service Provider, subject to the
                 requirements set forth in Section 2.2(a) with respect to
                 ingredient branding to be accorded to Company. For other
                 complementary products, services or technologies integrated
                 with the PMR Service, AOL and Company will negotiate in good
                 faith with one another regarding any co-branding or ingredient
                 branding requested by the third party providing such
                 complementary products, services or technologies. All
                 agreements that Company enters into with any Third Party
                 Service Providers shall explicitly provide that upon expiration
                 or termination of the Term of this Agreement, the Third Party
                 Service Provider shall not be restricted or limited in any
                 manner from providing its products and services to AOL, either
                 directly or through one or more third party transaction
                 processors, it being the intention that AOL will have the
                 ability to continue to offer the PMR Service with any related
                 products or services of Third Party Service Providers that were
                 offered during the Term as part of the PMR Service. AOL shall
                 be a named third party beneficiary of any such agreements.

           (d)   Development Committee. AOL and Company shall each designate an
                 ---------------------
                 individual to serve as development representatives (the
                 "Development Representatives") on a development committee (the
                 "Development Committee"). The initial Development
                 Representative appointed by each Party shall be subject to the
                 other Party's approval, not to be unreasonably withheld. Upon
                 AOL's request, the Development Committee shall also include a
                 development representative appointed by an AOL Strategic
                 Partner. If either Party replaces the initially designated
                 Development Representative, such Development Representative
                 must be replaced by a person of similar rank and stature unless
                 the
<PAGE>

                 parties otherwise agree. The Development Committee shall meet
                 on a regularly scheduled basis to discuss development
                 activities and priorities relating to the PMR Service, new
                 technological innovations, complementary products, services
                 and/or technologies, and other matters relating to the ongoing
                 development and maintenance of the PMR Service, including
                 without limitation competitive and business justifications for
                 implementing particular changes. Through the Development
                 Committee, the Parties will approve an updated and revised
                 Development Plan for the PMR Service at least once every six
                 (6) months. In the event that AOL requests that Company
                 integrate with the PMR Service complementary products, services
                 or technologies provided by an AOL Strategic Partner that are
                 reasonably necessary in order to maintain the PMR Service as a
                 market-competitive service, and such integration or
                 implementation would require Company to incur extraordinary
                 unanticipated fees or expenses (such as, by way of example,
                 extraordinary license fees or extraordinary additional hardware
                 expenses), the Development Committee shall discuss the matter
                 and attempt to agree on an appropriate allocation of such
                 expenses between the Parties.

           (e)   Additions As Part of General Obligations. All additions and
                 ----------------------------------------
                 changes provided hereunder will be developed, constructed,
                 programmed, hosted and maintained by Company as required
                 hereunder.

           (f)   AOL Right To Opt Out of Features. The features and functions of
                 --------------------------------
                 the AOL PMR Service and the Company PMR Service shall be the
                 same (subject to such user interface modifications as may be
                 developed by AOL pursuant to Section 2.1(a) that may
                 differentiate the appearance of the AOL PMR Service as it
                 appears on various services on the AOL Network), provided that
                 AOL shall have the right to decline to include in the AOL PMR
                 Service any features or functions of the PMR Service
                 implemented by Company in the Company PMR that AOL finds
                 unsuitable or undesirable for any reason.

           (g)   Data Mining and Market Research. AOL and Company shall within
                 sixty (60) days following the Effective Date, jointly agree in
                 writing upon a plan setting forth goals and procedures and
                 allocating responsibilities for storing and manipulating
                 Customer Data and generating such summary and aggregate reports
                 and other compilations of Customer Data as the Parties may
                 desire for purposes permitted under this Agreement (the "Data
                 Mining Plan").

2.   Ownership.
     ---------

     2.1.  Joint Ownership of PMR Service and Underlying Rights.
           ----------------------------------------------------

           (a)   Ownership and Assignments. Except as otherwise provided in this
                 -------------------------
                 Section 2 and subject to the limitations set forth in Section
                 2.1(b) and (c) of this Agreement, the PMR Service and all
                 proprietary rights in the PMR Service created, developed, owned
                 or other acquired or used during the Term, including all PMR
                 Rights, shall be jointly owned by Company and AOL in equal,
                 undivided shares, and Company and AOL shall each have all the
                 rights of a joint owner of such rights, subject to the
                 limitations and restrictions set forth in this Agreement. To
                 the extent such rights would, in the absence of any assignment
                 of rights, be owned by one Party, such Party hereby transfers
                 and assigns such co-ownership rights to the other Party.
                 Notwithstanding the foregoing, neither Company nor AOL shall
                 have any duty to account to one another or to pay to one
                 another any revenues derived from their respective exploitation
                 of the PMR Service or PMR Rights, except as specifically
                 provided in this Agreement. Any technology or other proprietary
                 rights or other rights created or acquired by or on behalf of a
                 Party after the Term (including any rights that would be
                 considered PMR Rights if created or acquired during the Term)
                 shall belong exclusively to the party creating such rights.
                 Without limiting the foregoing, each Party shall own exclusive
                 rights in any derivative works, modifications, enhancements,
                 adaptations or improvements it creates after the Term based on
                 or derived from any of the PMR Rights, subject to the joint
                 ownership of the underlying PMR Rights. Despite the foregoing,
                 at any time, including during the Initial Term, AOL will have
                 the right to modify, adapt, enhance and customize the user
                 interface of the PMR Service as it appears on the AOL Network
                 (or cause Company to do so on behalf of AOL), and any such
                 modifications, adaptations, enhancements and customizations,
                 and all proprietary rights therein, shall belong exclusively to
                 AOL. It is understood that the PMR Service that is jointly
                 owned by the Parties will itself have a full featured user
                 interface. Customization of such user interface undertaken by
                 AOL for which AOL would own all proprietary rights might
                 include, by way of example, customization to make the user
                 interface of the AOL PMR Service conform to the AOL Look and
                 Feel of one or more of the services comprising the AOL Service,
                 such as the aol.com, CompuServe or America Online brand
                 services. In addition, Company shall not acquire any ownership
                 rights in or to the AOL Namespace Technology; provided that
                 Company shall have the right to utilize such technology solely
                 for the PMR Service after the Term. It is understood that,
                 except as expressly set forth herein, the foregoing is intended
                 to provide each Party with joint
<PAGE>

                 rights in and to all aspects of the PMR Service. Each Party
                 will have the right to possession of all aspects of the jointly
                 owned technology, including source code and all documentation
                 of any nature whatsoever. Company shall promptly deliver to AOL
                 copies of all jointly owned technology, including source code
                 and documentation, as it is developed.

           (b)   License. Recognizing that the PMR Service will be developed, in
                 -------
                 part, by modifying, enhancing and creating derivative works
                 based upon the Dr. Koop Personal Medical Records System,
                 Company hereby grants to AOL a perpetual, non-terminable non-
                 exclusive license to any and all portions and elements of the
                 Dr. Koop Personal Medical Records System that are incorporated
                 in or become a part of the PMR Service. Such license includes
                 all rights that a joint owner of all proprietary rights would
                 have in the portions and elements of the Dr. Koop Personal
                 Medical Records System so incorporated into the PMR Service,
                 and Company acknowledges and agrees that, as set forth in
                 Section 2.1(a), Company and AOL will be joint owners of all
                 rights in the PMR Service.

           (c)   Third Party Agreements. All agreements that are entered into
                 ----------------------
                 with any third party with respect to the PMR Service shall
                 explicitly provide that upon expiration or termination of the
                 Term of this Agreement, such third party shall not be
                 restricted or limited in any manner from entering into a
                 similar agreement directly with AOL or a third party, it being
                 the Parties' intention that AOL will have the ability to
                 continue to offer the PMR Service with any and all features,
                 functions and capabilities that were offered during the Term as
                 part of the PMR Service. AOL shall be a named third party
                 beneficiary of any such agreements.

           (d)   Limits on Use by Company. Despite its joint ownership of the
                 ------------------------
                 PMR Service and PMR Rights, during the Initial Term, Company
                 will have the right to use the PMR Service and PMR Rights only
                 as follows: (i) to perform its duties under this Agreement,
                 (ii) to implement the Company PMR Service on the Dr. Koop Site,
                 and (iii) to authorize third parties to deploy, display or
                 offer the Company PMR Service, provided that any such third
                 party deploying, displaying or offering the Company PMR Service
                 during the Initial Term offers is in the business of offering
                 medical or health related products and services and is not in
                 the business of offering Interactive Services or Interactive
                 Sites targeted to consumers, and provided that Company shall
                 use commercially reasonable efforts to obtain from any such
                 third party a written agreement in a form approved by AOL
                 containing (a) commitments to provide AOL with a reasonably
                 prominent AOL-branded button
<PAGE>

                 on the first screen of such service, above-the-fold, promoting
                 the availability of the AOL PMR Service; and (b) commitments to
                 promote the availability of the AOL PMR Service in all offline
                 advertising, marketing and promotional materials relating to
                 such third party's deployment, display or offering of the
                 Company PMR Service, in accordance with specific details of
                 such branding and promotional requirements to be mutually
                 approved by AOL and Company, which the Parties agree not to
                 unreasonably withhold. Any such agreement with such third party
                 shall also contain such provisions as AOL reasonably requires
                 to protect AOL's trademark rights. Except as provided in this
                 Section 2.1(c), Company shall have no right, directly or
                 indirectly to utilize the PMR Service or the PMR Rights in any
                 other manner, including to deploy, display or offer the PMR
                 Service or the Company PMR Service (or any other personal
                 medical records service) through any Interactive Site or
                 Interactive Service or otherwise, or to permit any third party
                 directly or indirectly to deploy, display or offer the PMR
                 Service or the Company PMR Service (or any other personal
                 medical records service) through any other Interactive Site,
                 Interactive Service or otherwise. After the Initial Term,
                 subject only to express limitations set forth in this
                 Agreement, Company will have the right to implement and utilize
                 the PMR Service and PMR Rights in its sole and complete
                 discretion without limitation.

           (e)   Limits on Use by AOL. Despite its joint ownership of the PMR
                 --------------------
                 Technology and PMR Rights, during the Initial Term, AOL will
                 have the right to implement and deploy the PMR Technology and
                 PMR Rights and the PMR Service anywhere on the AOL Network, and
                 the right to sublicense to third parties the right to implement
                 and deploy the PMR Technology, the PMR Rights and PMR Service
                 outside the AOL Network. In the event AOL sublicenses the PMR
                 Service for deployment outside the AOL Network, AOL shall
                 require that any sublicensee provide Company ingredient
                 branding comparable to and subject to the minimum requirements
                 of the ingredient branding that AOL is required to accord to
                 Company as set forth in Section 2.2(a), and in the event that
                 AOL receives license fees for such sublicensing of the PMR
                 Service for deployment outside the AOL Network, AOL shall pay
                 Company an amount equal to * * * of such license fees which are
                 paid to AOL for the right to deploy the PMR Service during the
                 Initial Term. After the Initial Term, AOL will have the right
                 to implement and utilize the

                 PMR Technology, the PMR Rights and the PMR Service in its sole
                 and complete discretion without limitation.

           (f)   Limits on Use After the Term. Despite the provisions of
                 ----------------------------
                 Sections 2.1(a), (b), (c), (d) and (e) which, subject to the
                 provisions of Section 6.11, permit generally unlimited use of
                 the PMR Service and PMR Rights by each Party after the Initial
                 Term, at all times, including after the Initial Term and after
                 the Term, the rights of the Parties with respect to use of
                 Customer Data shall be subject to the limitations set forth in
                 Section 5.4 of Exhibit "B", and each Party shall utilize any
                 PMR Service Data and any other rights of any third party in
                 accordance with any privacy rights, any applicable laws, rules
                 and regulations and/or any contractual rights of such third
                 party, and shall indemnify the other Party hereto against any
                 claims of any such third party arising out of or related to the
                 use by such Party of such Customer Data or PMR Service Data.

           (g)   Facilitation of Licensing of Tools and Technology. To the
                 -------------------------------------------------
                 extent that the ongoing use and/or maintenance of the PMR
                 Service requires access to proprietary tools or technology of
                 either Party and/or of third parties, each Party agrees to make
                 such Party's necessary tools and/or technology available to the
                 other Party at no charge for the purpose of using and
                 maintaining the PMR Service, agrees not to interfere with the
                 other Party's ability to obtain any necessary licenses to such
                 tools and/or technology available from third parties, and
                 agrees to use commercially reasonable efforts to facilitate
                 contacts and discussions between any such third parties and the
                 other Party to this Agreement to obtain any such necessary
                 licenses.


     2.2.  Ownership of AOL PMR Service and Company PMR Service.
           ----------------------------------------------------

           (a)   AOL Ownership of AOL PMR Service. Subject to the provisions of
                 --------------------------------
                 Section 2.1 concerning ownership of the PMR Service and PMR
                 Rights, AOL will own all other aspects of the AOL PMR Service.
                 Without limiting the foregoing: (1) AOL shall retain ownership
                 of all trademarks and service marks used in connection with the
                 AOL PMR Service (other than marks licensed from Company); (2)
                 AOL will own all right, title and interest in and to all
                 aspects of the Advertising, transactional and promotional
                 spaces within the AOL PMR Service (including, without
                 limitation, Advertising, transactional and promotional spaces
                 on any AOL forms or pages which are included within, precede,
                 follow, frame or otherwise are associated with the Licensed
                 Content, the AOL PMR Service and/or any Linked Interactive
                 Sites), including without limitation all ad banners and
                 sponsorship opportunities for the AOL PMR Service, but not
                 including the Backend; (3) AOL will have the
<PAGE>

                 exclusive right to sell Advertising, transactions and
                 promotions within the AOL PMR Service and Company will have no
                 right to sell any such item and the specific advertising
                 inventory within any AOL forms or pages or the AOL PMR Service
                 and all aspects of its sale and use will be as determined
                 solely by AOL; (4) AOL will own all URL's, screennames and
                 other screen space attributes of the AOL PMR Service; and (5)
                 except as otherwise expressly provided in this Agreement, AOL
                 will own and control all relationships with AOL Members, AOL
                 End-Users, AOL PMR Users, AOL PMR Members and other users of
                 the AOL PMR Services. In addition, the AOL PMR Service will be
                 branded by AOL in its sole and complete discretion and all such
                 branding will be owned by AOL, provided that, during the
                 Initial Term, AOL will provide Company ingredient branding such
                 as "Powered by drkoop.com, inc." on the first screen of the AOL
                 PMR Service appearing on any portion of the AOL Network and on
                 all subsequent screens of the AOL PMR Service appearing on any
                 portion of the AOL Network, provided that AOL may withhold
                 Company ingredient branding on any screen other than the
                 initial screen where AOL is providing ingredient or co-branding
                 to a third party. AOL shall also have the right to provide
                 Company greater branding determined by AOL in its discretion.
                 Without limiting the foregoing rights, AOL may also provide one
                 or more Third Party Service Providers with branding on the AOL
                 PMR Service, and may require Company to provide co-branding to
                 one or more Third Party Service Providers as provided in
                 Section 1.6(c). AOL will at all times during the Term have the
                 right to continue to provide ingredient branding and/or co-
                 branding as provided above, but its obligations to provide any
                 such branding will expire at the end of the Initial Term.
                 Subject to the provisions of this Section 2.2(a), AOL and
                 Company shall mutually agree on the placement and appearance of
                 the ingredient branding provided to Company by AOL, with
                 Company's approval not to be unreasonably withheld. AOL shall
                 have a period of one hundred twenty (120) days following the
                 Effective Date to conduct due diligence with respect to whether
                 Company has the right to grant to AOL the rights granted to AOL
                 by Company pursuant to this Agreement. Notwithstanding anything
                 to the contrary set forth in this Section 2.2(a), in the event
                 AOL reasonably concludes that Company does not have the right
                 to grant material rights granted to AOL pursuant to this
                 Agreement, or that the exercise by AOL of material rights
                 granted by Company to AOL pursuant to this Agreement will
                 likely subject Company and/or AOL to legal action by a third
                 party, AOL shall have no obligation to provide or require its
                 sublicensees to provide any ingredient branding or co-branding
                 to Company pursuant to this Agreement, without limiting any of
                 AOL's other rights or remedies.

           (b)   Company Ownership of Company PMR Service. Subject to the
                 ----------------------------------------
                 provisions of Section 2.1 concerning ownership of the PMR
                 Service and PMR Rights, Company will own all other aspects of
                 the Company PMR Service. Without limiting the foregoing: (1)
                 Company shall retain ownership of all trademarks and service
                 marks used in connection with the Company PMR Service (other
                 than those marks, if any, licensed from AOL - it being
                 understood that Company has no such rights under this
                 Agreement); (2) subject to the rights of AOL under the
                 Interactive Services Agreement, Company will own all right,
                 title and interest in and to all aspects of the Advertising,
                 transactional and promotional spaces within the Company PMR
                 Service (including, without limitation, Advertising,
                 transactional and promotional spaces on any Company forms or
                 pages which are included within, precede, follow, frame or
                 otherwise are associated with the Company PMR Service and/or
                 any Linked Company Interactive Sites), including without
                 limitation all ad banners and sponsorship opportunities for the
                 Company PMR Service; (3) subject to the rights of AOL under the
                 Interactive Services Agreement, Company will have the exclusive
                 right to sell Advertising, transactions and promotions within
                 the Company PMR Service; (4) subject to the provisions of
                 Section 2.1(a) with respect to AOL's ownership of AOL Namespace
                 Technology, Company will own all URL's, screennames and other
                 screen space attributes of the Company PMR Service; and (5)
                 Company will own and control all relationships with users of
                 the Company PMR Service.

           (c)   General Intent. The provisions of Sections 2.2(a) and (b) are
                 --------------
                 intended to reserve for each Party rights in or to the
                 particular front-end implementation of the PMR Service (i.e.,
                 the AOL PMR Service or the Company PMR Service, as applicable)
                 solely to the extent the rights in such implementation are
                 different from the rights in or to the PMR Service and PMR
                 Rights. The Parties agree that, subject to the terms and
                 conditions of this Agreement, all proprietary rights in the
                 Backend of the PMR Service and PMR Rights are intended to be
                 solely owned by Company, except that Customer Data and all
                 rights therein shall be jointly owned, subject to the terms and
                 conditions of this Agreement, regardless of whether such
                 Customer Data is collected, manipulated or resident at the
                 Backend or the front end, provided that those portions of
                 Customer Data generated by Company through Permitted Products
                 and Services shall belong exclusively to Company.


3.   Management of AOL PMR Service by Company for AOL.
     ------------------------------------------------

     3.1.  Management. Except as expressly provided herein, during the Term,
           ----------
           Company will, on behalf of AOL, develop, implement, manage, maintain,
<PAGE>

           host and operate the PMR Service for use by AOL as the AOL PMR
           Service (including reviewing, deleting, editing, creating, updating
           and otherwise managing all Content available on or through the AOL
           PMR Service) in strict accordance with the terms of this Agreement.
           Except as expressly provided herein and in the Interactive Services
           Agreement, all Content on the AOL PMR Service, including without
           limitation, all Products, Links, buttons, promotions, sponsorships or
           similar Content and all features and transaction opportunities
           available from the PMR Service will be as agreed to by the Parties as
           described in the Development Plan, with only such changes as are made
           or approved by AOL; provided that Company may make changes to the
           non-core functionality of the AOL PMR Service as reasonably necessary
           to update and maintain the AOL PMR Service in the ordinary course of
           management of such service upon written notice to AOL, provided such
           changes do not materially affect the functioning of, or Products or
           Content available through, the AOL PMR Service and do not modify the
           user interface or user registration or access process or methodology.
           AOL may establish written overall guidelines regarding such changes
           that will eliminate the need for approval or notification of changes
           on a case by case basis if such changes are within the agreed upon
           guidelines. Except as contemplated by the foregoing, Company will not
           place Content on the AOL PMR Service or make any change to the PMR
           Service, or any aspect thereof, including the user interface, without
           AOL's prior approval and AOL has sole control over all such aspects.
           In addition, AOL will have the right to establish and provide to
           Company reasonable rules governing the permitted Content to be
           provided by third parties as part of the AOL PMR Service, and to
           cause Company to remove any materially nonconforming Content from the
           AOL PMR Service and to refuse such Content for the AOL PMR Service
           (such as Content from specific third parties or specific Products).

           2.2, AOL has and will retain control and management over all aspect
           of the AOL PMR Service, including all Advertising, promotional and
           transactional space for the AOL PMR Service and Company is merely

     3.2.  Hosting; Communications. Company will be responsible during the
           -----------------------
           Initial Term and the Tail Period (if applicable) for all
           communications, hosting and connectivity costs and expenses
           associated with the AOL PMR Service, provided that, AOL at its
           discretion and cost may host any or all of the AOL PMR Service,
           including the initial screen or elements thereof. Company will
           provide all computer hardware (e.g., servers, network devices,
           routers, switches, telephones and other similar equipment) and all
           computer software (e.g., web servers, operating systems,
           applications, databases and other similar resources) necessary to
           make the AOL PMR Service available on and through the AOL Network. To
           the extent necessary for the AOL PMR Service to be competitive with
           the top two then-current market leaders in personal medical records

           services as set forth in Section 1 of Exhibit "C", Company will
           utilize a dedicated high speed connection to maintain quick and
           reliable transport of information to and from the Company Data Center
           and the Internet and T1 or similar connections to and from the
           Company Data Center and AOL's servers. AOL will be given the
           opportunity to review and comment upon significant changes to
           Company's communications and hosting equipment and architecture for
           the PMR Service. AOL may elect to have Company provide some or all of
           the operation and hosting services provided in this Section 3 to AOL
           during the Extension Period (if applicable). Company shall provide to
           AOL on a weekly basis a report specifying for the prior week
           aggregate usage, page views, Impressions and new registered users for
           the AOL PMR Service, and setting forth such additional information
           and data regarding usage of the AOL PMR Service as AOL reasonably
           requests.

     3.3.  Operating Standards. In its operation and hosting of the PMR Service,
           -------------------
           Company will ensure that the PMR Service substantially complies at
           all times with the Operating Standards.

     3.4.  Customer Service. In its operation and hosting of the PMR Service,
           ----------------
           Company will provide the customer service and support specified for
           the AOL PMR Service on Exhibit D.

     3.5.  Links to Other Sites.
           --------------------

           (a)   No Links. There will be no Linked Interactive Site for the AOL
                 --------
                 PMR Service except as expressly approved by AOL; provided,
                 however, that notwithstanding the foregoing but subject to
                 Section 3.5(b), Company may include a Link to third party
                 Interactive Sites for contextual or editorial purposes so long
                 as (a) such Links only link to the specific contextually
                 relevant page(s) of such third party Interactive Site, which
                 such page(s) appear in a "second" browser window that is
                 smaller than the original Company browser window; (b) Company
                 includes navigational ability within such page(s) for AOL
                 Members to return to the AOL PMR Service; and (c) Company shall
                 use commercially reasonable efforts to ensure that such page(s)
                 do not include Links to areas outside of a Company Interactive
                 Site or the AOL PMR Service. In the event AOL is dissatisfied
                 with any Link from the AOL PMR Service and AOL so notifies
                 Company in writing, then Company shall use its commercially
                 reasonable best efforts to block access by AOL Members to such
                 Link. In the event that Company cannot, through its
                 commercially reasonable best efforts, block access by AOL
                 Members to such Link in question, then Company shall provide
                 AOL prompt written notice of such fact. AOL may (in addition to
                 AOL's other rights under this Agreement, at law or in equity)
                 then, at its option, either (i) restrict access from the AOL
                 Network to the
<PAGE>

                 Link in question using technology available to AOL or (ii) in
                 the event access cannot be restricted, direct Company to remove
                 any such Link. Company will cooperate with AOL's reasonable
                 requests to the extent AOL elects to implement any such access
                 restrictions. AOL will have no obligations of any kind with
                 respect to any Linked Interactive Site (other than a Linked
                 Interactive Site owned or controlled by AOL). Company will be
                 responsible for any hosting or communication costs associated
                 with any Linked Company Interactive Sites (including, without
                 limitation, the costs associated with (i) any agreed-upon
                 direct connections between the AOL Network and such Linked
                 Company Interactive Site, or (ii) a mirrored version of such
                 Linked Company Interactive Site).

           (b)   Traffic Flow. Company will ensure that AOL traffic is either
                 ------------
                 kept within a Linked Company Interactive Site or channeled back
                 into the AOL Network. To the extent that AOL notifies Company
                 in writing that, in AOL's judgment, links from the Linked
                 Company Interactive Site cause more than a de minimus amount of
                 AOL traffic to be diverted outside of such site and the AOL
                 Network in a manner that has a detrimental effect on the
                 traffic flow of the AOL audience, then Company will promptly
                 reduce the number of Links out of such site(s). If Company
                 cannot or does not so limit diverted traffic from the Linked
                 Company Interactive Site, AOL reserves the right to terminate
                 the Links from the AOL Network to the Linked Company
                 Interactive Site at issue.

           (c)   Competitive Services. Company will not promote, and will ensure
                 --------------------
                 that Third Party Service Providers do not promote, Interactive
                 Services on pages in the AOL PMR Service other than those that
                 AOL controls. To the extent technically possible, Company will
                 limit or prevent disclosure to a Third Party Service Provider
                 that a specific customer visit is from an AOL Customer, unless
                 otherwise permitted by AOL.


4.   Exclusivity.
     -----------

     4.1.  No Similar or Competitive Products or Services. During the Term,
           ----------------------------------------------
           neither the Company nor any of its Affiliates will provide to any
           Third Party for use on an Interactive Site, as part of any product or
           service other than the PMR Service, any Products or services
           substantially similar to the Products or services offered on the PMR
           Service.

     4.2.  Limitations on Marketing of Products and Services. Without limiting
           -------------------------------------------------
           the restrictions set forth in Exhibit B on solicitation of AOL
           Members, Company will not during the Term solicit AOL Members for any
           products or services except as permitted in this Section 4. Subject
           to the terms and
<PAGE>

           conditions of this Agreement, Company shall have the right, during
           the Initial Term, to use Member Information that constitutes part of
           the PMR Service Data to solicit AOL PMR Members solely through the
           AOL Network and solely for Permitted Products and Services. As used
           herein the term "Permitted Products and Services" shall mean those
           health and medical products and services approved in writing by AOL.
           AOL shall provide an initial list of Permitted Products and services
           not later than ninety (90) days prior to the projected Launch Date
           set forth in the Development Plan. AOL will consider and discuss in
           good faith with Company on an annual basis expanding the definition
           of Permitted Products and Services to include additional health and
           medical products and services that Company desires to market to AOL
           PMR Members and that require medical or health industry specific
           knowledge and/or expertise not possessed by AOL, provided that AOL
           shall have no obligation to approve the inclusion within such
           definition of any product or service competitive with a product or
           service offered by AOL or an AOL Strategic Partner or to which AOL
           has made commitments of exclusivity. AOL agrees, upon Company's
           request, to use commercially reasonable efforts to facilitate
           contacts and discussions between any such third parties and Company
           to explore whether a mutually advantageous business relationship may
           be established between such third party and Company. During the Tail
           Period or Extension Period, subject to the terms and conditions of
           this Agreement, Company shall have the right to use Member
           Information that constitutes part of the PMR Service Data to solicit
           Existing Customers only, solely through the AOL Network and solely
           for Permitted Products and Services, provided that AOL may in its
           sole discretion elect to permit Company during the Tail Period or
           Extension Period to solicit all AOL PMR Members rather than only
           Existing Customers, subject to the other limitations of this
           sentence. Any software, products and services developed by Company to
           implement the Permitted Products and Services and all proprietary
           rights therein shall belong solely to Company. Company shall pay to
           AOL * * * of PPS Front End Revenues generated during the Term of this
           Agreement.


5.   Revenue Sharing.

           any sharing of revenues with respect to the PMR Service, the Company
           PMR Service or the AOL PMR Service (including any Advertising

           AOL shall retain all revenues of any nature arising out of or in
           connection with the AOL PMR Service and Company shall, subject to the
           provisions of the Interactive Services Agreement, retain all revenues
           from the Company PMR Service. Despite the foregoing, the Company PMR
           Service shall be considered part of the * * * for all purposes of
           revenue sharing between the Parties pursuant to the Interactive
           Services Agreement. In addition, each Party shall retain any rights
           and revenues it receives from its use of or implementation of the PMR
           Service or the PMR Rights; without limiting the foregoing, in the
           event that Company receives any revenues from any third party in
           connection with the Backend of the PMR Service (such as through data
           or content agreements with medical providers, insurance companies,
           etc.), it shall retain such revenues.

     5.2.  Revenue Sharing.
           ---------------

           (a)   In consideration of the license to the Dr. Koop Personal

                 Million Dollars ($8,000,000), payable as follows: * * *. In the

                 or 6.6, or pursuant to Section 6.7 as a result of a Change of
                 Control of Company, Company shall refund to AOL a pro rata
                 portion of such Eight Million Dollar ($8,000,000), with the
                 amount of such refund diminishing on a straight line basis from
                 the Effective Date to the date of such termination, calculated
                 daily over such four (4) year period. In the event AOL
                 exercises its "Buy-Out Right" pursuant to Section 7.3 of the
                 Interactive Services Agreement, AOL's right to receive a refund
                 pursuant to this Section 5.2(a) shall terminate.

           (b)   Other than the payments expressly provided for in this

                 will have no obligation to repay or otherwise provide Company
                 with compensation for such services, other than the mutual
                 covenants and conditions of this Agreement and the Interactive
                 Services Agreement.

<PAGE>

           (c)   AOL shall pay to Company * * * of CPMR Revenues generated

                 AOL's intention to enter into one or more Consumer Accumulative
                 Transactions with third parties and that it may be necessary
                 for AOL to commit to pay such third party(ies) a portion of
                 CPMR Revenues. In the event AOL fails to enter into an
                 agreement within six (6) months following the Effective Date
                 pursuant to which AOL agrees to pay a third party a portion of
                 CPMR Revenues, AOL shall pay to Company * * * of CPMR Revenues
                 generated during the remainder of the Initial Term from

                 the AOL PMR Service and all services required of Company during
                 the Tail Period hereunder an amount equal to the greater of (i)
                 the Cost Plus Reimbursement for such services provided during
                 the Tail Period pursuant to Section 3 or (ii) * * * of CPMR

                 generated during the Extension Period. In addition, for any
                 services pursuant to Section 3, if any, that AOL requests
                 Company to provide during the Extension Period, AOL will pay
                 Company an amount equal to the Cost Plus Reimbursement for such
                 services. If there is an Extension Period, Company shall pay

           herein as the "Term."

     6.2.  Initial Term. Unless earlier terminated as set forth herein, the

           Services Agreement ("Initial Term"); provided that, if AOL terminates
           the Interactive Services Agreement prior to the expiration of its
           initial term pursuant to Section 7.2, 7.4, 7.5 or 7.6 of the
           Interactive Services Agreement, the Initial Term will, at AOL's
           discretion, either terminate concurrently with termination of the
           Interactive Services Agreement or continue for the entire proposed
           initial term of the Interactive Services Agreement (as if not
           terminated). Despite the foregoing, it is understood that this
           Agreement is separate from and severable from the Interactive
           Services Agreement and that such agreements may be terminated or
           extended separately and that no termination of this Agreement will
           automatically terminate the Interactive Services Agreement.

     6.3.  Termination Prior to Launch. AOL will have the right to terminate
           ---------------------------
           this Agreement prior to the Launch Date of the AOL PMR Service if, as
           a result of Company's failure to fulfill its obligations, the
           Development Plan is not agreed to within the period specified in
           Section 1.1 or the Launch Date of the AOL PMR Service fails to occur
           by the milestone date specified therefor in the Development Plan. The
           Development Plan may include mutually agreed grace periods for
           achievement of the Launch Date and may include mutually agreed
           mechanisms for extending the milestone date if delays are caused by
           AOL's failure to fulfill its obligations.

     6.4.  Termination for Breach. Either Party may terminate this Agreement at
           ----------------------
           any time in the event of a material breach by the other Party which

     6.5.  Special Termination by AOL. AOL shall have the right to terminate
           --------------------------
           this Agreement immediately by providing Company written notice (a) in
           the event any claim or proceeding is brought against Company for
           professional negligence or wrongdoing, including without limitation,
           regarding malpractice or practicing medicine without the appropriate
           license(s), which claim appears on its face to be potentially
           meritorious or appears to have the potential for significantly
           damaging or tarnishing the reputation of the Company or AOL; (b) in
           the event of any act, omission, event or other cause that would allow
           AOL to terminate the Interactive Services Agreement; provided that
           all proper notice and cure periods (if applicable) are given, and
           provided that AOL terminates the Interactive Services Agreement, or
           (c) upon any event giving rise to a material claim for
           indemnification by Company hereunder based upon Licensed Content,
           provided that such termination right is exercised within ninety (90)
           days after the circumstance giving rise to such right of termination.

     6.6.  Termination for Bankruptcy/Insolvency or Changes in Business. Either
           ------------------------------------------------------------
           Party may terminate this Agreement immediately following written
           notice to the other Party if the other Party (i) ceases to do
           business in the normal course, (ii) becomes or is declared insolvent

           calendar days or (iv) makes an assignment for the benefit of
           creditors.

     6.7.  Termination on Change of Control. In the event of a Change of Control
           --------------------------------
           of AOL during the Initial Term or a Change of Control of Company
           during the Initial Term that results in a Specified Entity
           (identified as such as of the date the related definitive agreement
           is entered into) acquiring substantially all of the assets of Company
           or acquiring, either individually or as part of a group (within the
           meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
           Act of 1934, as amended) beneficial ownership (within the meaning of
           Rule 13d-3 promulgated under such Act) of more than * * * of either

           the combined voting power of the then outstanding voting securities
           of Company entitled to vote generally in the election of directors,

           Period to discontinue according ingredient branding to Company as

           at any time upon thirty (30) days prior written notice to Company.
           Company shall assure that it continues to perform any services it is

           not experience any material diminution in quality or timeliness of
           performance of services by Company during such periods.

     6.10. Transition Period and Facilitation. Company will facilitate the
           ----------------------------------
           conversion of AOL Customers who enroll in the AOL PMR Service
           hereunder to a new AOL-sourced solution at the expiration or
           termination of the Term of this Agreement for any reason and will
           cooperate with all of AOL's reasonable requests in such conversion
           process (provided that AOL shall pay for Company's services as
           provided in Section 3.2(b)). At AOL's request, Company shall,
           commencing eighteen (18) months prior to the end of the Initial Term,
           prepare a detailed transition plan for AOL's review and approval,
           including plans for data conversion and any associated software
           development required to convert to a new AOL-sourced solution.
           Company shall complete such transition plan and obtain AOL's approval
           thereof not later than twelve (12) months prior to the end of the
           Initial Term. During the period of such conversion, AOL will have the
           right, but not the obligation, to have Company provide all of the
           services hereunder for up to eighteen (18) months (as selected by AOL
           in its discretion) after the Initial Term or during the Tail Period
           or after any expiration or termination of the Term of this Agreement
           for any reason whatsoever (the "Transition Period"). AOL may
           terminate the Transition Period at any time upon thirty (30) days
           prior written notice to Company. During the Transition Period, the
           terms of this Agreement will continue to apply, including all revenue
           sharing arrangements in effect immediately prior to the commencement
           of the Transition Period and all payments by AOL for services
           provided by Company, except that AOL may elect at any time during the

           incremental transition services provided during the Transition Period
           that would not otherwise have been provided by Company on a Cost Plus
           Reimbursement basis. Company acknowledges and agrees that the
           provision of such transition services are critical to AOL's business
           and reputation and that monetary damages will be inadequate to
           compensate AOL for damages in the event Company fails to provide such
           transition services; accordingly, Company agrees that, without
           limitation of any of AOL's other rights and remedies, AOL shall be
           entitled to injunctive relief
<PAGE>

            and specific performance remedies to compel Company to provide such
            transition services.

     6.11.  Rights Following Termination. Notwithstanding anything to the
            ----------------------------
            contrary set forth in this Agreement, in the event of a termination
            of this Agreement by AOL pursuant to Section 6.4, 6.5 or 6.6, or
            pursuant to Section 6.7 as a result of a Change of Control of
            Company, Company shall have no rights following such termination to
            use any Customer Data for any purpose whatsoever. In the event of
            any other expiration or termination of this Agreement, Company and
            AOL shall have the rights following such expiration or termination
            of a joint owner of all proprietary rights in the PMR Service and
            the PMR Service Data, subject to those limitations set forth in
            Section 2.1(e).

     6.12.  Press Releases. Upon execution, the Parties shall jointly prepare a
            --------------
            press release announcing this Agreement, which release shall be
            disseminated at a mutually agreeable time. Thereafter, press
            releases and other disclosures will be governed by the terms of
            Section IV of Exhibit "B".

provide Company to use any of the Marks of AOL other than in connection with the
AOL PMR Service. This Section shall survive the completion, expiration,
termination or cancellation of this Agreement.

commercial e-mail (i.e., "spam") or other online communications through or into
AOL's products or services, absent a Prior Business Relationship. For purposes

transaction through the AOL PMR Service); or (ii) provided information to
Company through a contest, registration, or other communication, which included

to AOL Members which are otherwise permitted hereunder will (a) include a
prominent and easy means to "opt-out" of receiving any future commercial e-mail
communications from Company and (b) shall also be subject to AOL's then-standard
restrictions on distribution of bulk e-mail (e.g., related to the time and
manner in which such e-mail can be distributed through or into the AOL product
or service in question).

       (b)   Company shall ensure that its collection, use and disclosure of
information obtained from AOL Members under this Agreement ("Member
Information") complies with (i) all applicable laws and regulations and (ii)
AOL's standard privacy policies, available on the AOL Service at the keyword
term "Privacy" (or, in the case of the Company Internet Site, Company's standard
privacy policies so long as such policies are prominently published on the site
and provide adequate notice, disclosure and choice to Members regarding
Company's collection, use and disclosure of user information). Company will not
disclose Member Information collected hereunder to any third party in a manner
that identifies AOL Members as end users of an AOL product or service or use
Member Information collected under this Agreement to market another Interactive
Service.

       -----------------
or its agents shall (i) be subject to AOL's policies on use of the email
functionality, including but not limited to AOL's policy on unsolicited bulk
email, (ii) be sent only to AOL Members requesting to receive such newsletters,
(iii) not contain Content which violates AOL's Terms of Service, and (iv) not
contain any advertisements, marketing or promotion for any other Interactive
Service .

5.3    AOL Member Communications. To the extent Company is otherwise permitted
       -------------------------
to send communications to AOL Members (in accordance with the other requirements
contained herein): in any such communications to AOL Members on or off the
Company Internet Site (including, without limitation, e-mail solicitations),
Company will limit the subject matter of such communications to those categories
of products, services and/or content that are specifically contemplated by this
Agreement and will not encourage AOL Members to take any action inconsistent
with the scope and purpose of this Agreement, including without limitation, the
following actions: (i) using an Interactive Site other than the Company Internet
Site for the purchase of Products, (ii) using Content other than the Licensed
Content; (iii) bookmarking of Interactive Sites; or (iv) changing the default
home page on the AOL browser. Additionally, with respect to such AOL PMR User
communications, in the event that Company encourages an AOL PMR User to purchase
products through such communications, Company shall ensure that (a) the AOL
Network is expressly promoted as the primary means through which the AOL PMR
User can access the Company Internet Site (including without limitation by
stating the applicable Keyword Search Term and including direct Links to
specific offers within the Company Internet Site) and (b) any Link to the
Company Internet Site will link to a page which indicates to the AOL PMR User
that such user is in a site which is affiliated with the AOL Network.

5.4    Customer Data; AOL Data. Any data provided by customers that is generated
       -----------------------
directly from the * * * or produced by Company in performing its obligations in
managing such service, including, without limitation, customer names, addresses,
credit card information and AOL screennames is referred to herein as the
"Customer Data"). Notwithstanding the joint ownership of the Customer Data
provided in Section 2.1(a), Company (a) shall comply with all paragraphs of this
Section 5, (b) shall provide users the right to have their Customer Data deleted
from any database created by or on behalf of Company, (c) shall not have the
right to use the Customer Data to market or promote any consumer direct
information, services or products reasonably construed to be in competition with
the PMR

consumers to view, enter or modify Customer Data; and (d) shall not have the
right to sell, license or provide Customer Data (whether in the form of
individual data or summary or aggregate reports or compilations of Customer
Data) to any third party without AOL's prior written consent. Without limiting
the foregoing, Company's and AOL's use of the Customer Data shall be subject to
the terms of this Agreement and AOL's then-applicable privacy policies; provided
that both Parties shall use customer-specific medical profile information on a
customer-by-customer basis in accordance with both Parties' applicable privacy
policies. Any data provided by AOL to Company (e.g., usage reports) (the "AOL
Data") shall be and remain the property of AOL, and the AOL Data will be
promptly returned to AOL by Company in the form in which such data is maintained
by Company or, if AOL so elects, will be destroyed, upon (i) AOL's request, (ii)
expiration or termination of this Agreement for any reason, or (iii) with
respect to any particular AOL Data, on such earlier date that the same is no
longer required by Company in order to provide the services required hereunder.
Company will not use the AOL Data for any purpose other than that of providing
such services, nor will the AOL Data, or any part thereof, be disclosed, sold,
assigned, leased, or otherwise disposed of to third parties by Company or
commercially exploited by or on behalf of Company, its employees or agents.
Company will not possess or assert any lien or other right against or to the AOL
Data. The Parties agree to amend the provisions of this paragraph from time to
time to in good faith to the extent necessary to comply with applicable law,
rule or regulation; provided that if any such amendment to the provisions of
this paragraph has, or is likely to have, an adverse effect on either Party,
then such Party may refer such matter to the Management Committee for
resolution.

       --------------
THIS AGREEMENT WERE NEGOTIATED TO REFLECT AN INFORMED, VOLUNTARY ALLOCATION
BETWEEN THEM OF ALL RISKS (BOTH KNOWN AND UNKNOWN) ASSOCIATED WITH THE
TRANSACTIONS CONTEMPLATED HEREUNDER. THE LIMITATIONS AND DISCLAIMERS RELATED TO
WARRANTIES AND LIABILITY CONTAINED IN THIS AGREEMENT ARE INTENDED TO LIMIT THE
CIRCUMSTANCES AND EXTENT OF LIABILITY. THE PROVISIONS OF THIS SECTION VI SHALL
BE ENFORCEABLE INDEPENDENT OF AND SEVERABLE FROM ANY OTHER ENFORCEABLE OR
UNENFORCEABLE PROVISION OF THIS AGREEMENT.


VII.   ARBITRATION

       (a)   The Parties shall act in good faith and use commercially reasonable
efforts to promptly resolve any claim, dispute, claim, controversy or
disagreement (each a "Dispute") between the Parties or any of their respective
subsidiaries, affiliates, successors and assigns under or related to this
Agreement or any document executed pursuant to this Agreement or any of the
transactions contemplated hereby. If the Parties cannot resolve the Dispute
within such timeframe, the Dispute shall be submitted to the Management
Committee for resolution. For ten (10) days after the Dispute was submitted to
the Management Committee, the Management Committee shall have the exclusive
right to resolve such Dispute; provided further that the Management Committee
shall have the final and exclusive right to resolve Disputes arising from any
provision of this Agreement which expressly or implicitly provides for the
Parties to reach mutual agreement as to certain terms. If the Management
Committee is unable to amicably resolve the Dispute during the ten (10) day
period, then the Management Committee will consider in good faith the
possibility of retaining a third party mediator to facilitate resolution of the
Dispute. In the event the Management Committee elects not to retain a mediator,
the Dispute will be subject to the resolution mechanisms described below.
"Management Committee" shall mean a committee made up of a senior executive from
each of the Parties for the purpose of resolving Disputes under this Section and
generally overseeing the relationship between the Parties contemplated by this
Agreement. Neither Party shall seek, nor shall be entitled to seek, binding
outside resolution of the Dispute unless and until the Parties have been unable
to amicably resolve the dispute as set forth in this paragraph (a) and then,
only in compliance with the procedures set forth in this Section.

       (b)   Except for Disputes relating to issues of (i) proprietary rights,
including but not limited to intellectual property and confidentiality, and (ii)
any provision of this Agreement which expressly or implicitly provides for the
Parties to reach mutual agreement as to certain terms (which shall be resolved
by the Parties solely and exclusively through amicable resolution as set forth
in paragraph (a), any Dispute not resolved by amicable resolution as set forth
in paragraph (a) shall be governed exclusively and finally by arbitration. Such
arbitration shall be conducted by the American Arbitration Association ("AAA")
in Washington, D.C. and shall be initiated and conducted in accordance with the
Commercial Arbitration Rules ("Commercial Rules") of the AAA, including the AAA
Supplementary Procedures for Large Complex Commercial Disputes ("Complex
Procedures"), as such rules shall be in effect on the date of delivery of a
demand for arbitration ("Demand"), except to the extent that such rules are
inconsistent with the provisions set forth herein. Notwithstanding the
foregoing, the Parties may agree in good faith that the Complex Procedures shall
not apply in order to promote the efficient arbitration of Disputes where the
nature of the Dispute, including without limitation the amount in controversy,
does not justify the application of such procedures.


                              Exhibit B - Page 8
<PAGE>

       (c)   The arbitration panel shall consist of three arbitrators. Each
Party shall name an arbitrator within ten (10) days after the delivery of the
Demand. The two arbitrators named by the Parties may have prior relationships
with the naming Party, which in a judicial setting would be considered a
conflict of interest. The third arbitrator, selected by the first two, shall be
a neutral participant, with no prior working relationship with either Party. If
the two arbitrators are unable to select a third arbitrator within ten (10)
days, a third neutral arbitrator will be appointed by the AAA from the panel of
commercial arbitrators of any of the AAA Large and Complex Resolution Programs.
If a vacancy in the arbitration panel occurs after the hearings have commenced,
the remaining arbitrator or arbitrators may not continue with the hearing and
determination of the controversy, unless the Parties agree otherwise.

       (d)   The Federal Arbitration Act, 9 U.S.C. Secs. 1-16, and not state
law, shall govern the arbitrability of all Disputes. The arbitrators shall allow
such discovery as is appropriate to the purposes of arbitration in accomplishing
a fair, speedy and cost-effective resolution of the Disputes. The arbitrators
shall reference the Federal Rules of Civil Procedure then in effect in setting
the scope and timing of discovery. The Federal Rules of Evidence shall apply
in toto. The arbitrators may enter a default decision against any Party who
-------
fails to participate in the arbitration proceedings.

       (e)   The arbitrators shall have the authority to award compensatory
damages only. Any award by the arbitrators shall be accompanied by a written
opinion setting forth the findings of fact and conclusions of law relied upon in
reaching the decision. The award rendered by the arbitrators shall be final,
binding and non-appealable, and judgment upon such award may be entered by any
court of competent jurisdiction. The Parties agree that the existence, conduct
and content of any arbitration shall be kept confidential and no Party shall
disclose to any person any information about such arbitration, except as may be
required by law or by any governmental authority or for financial reporting
purposes in each Party's financial statements.

       (f)   Each Party shall pay the fees of its own attorneys, expenses of
witnesses and all other expenses and costs in connection with the presentation
of such Party's case (collectively, "Attorneys' Fees"). The remaining costs of
the arbitration, including without limitation, fees of the arbitrators, costs of
records or transcripts and administrative fees (collectively, "Arbitration
Costs") shall be born equally by the parties. Notwithstanding the foregoing, the
arbitrators may modify the allocation of Arbitration Costs and award Attorneys'
Fees in those cases where fairness dictates a different allocation of
Arbitration Costs between the Parties and an award of Attorneys' Fees to the
prevailing Party as determined by the arbitrators.

       (g)   Any Dispute that is not subject to final resolution by the
Management Committee or to arbitration under this Section or law (collectively,
"Non-Arbitration Claims") shall be brought in a court of competent jurisdiction
in the State of New York. Each Party irrevocably consents to the exclusive
jurisdiction of the courts of the State of New York and the federal courts
situated in the State of New York, over any and all Non-Arbitration Claims and
any and all actions to enforce such claims or to recover damages or other relief
in connection with such claims or to enforce a judgment rendered in an
arbitration proceeding.

8.5    No Waiver.  The failure of either Party to insist upon or enforce strict
       ---------
performance by the other Party of any provision of this Agreement or to exercise
any right under this Agreement shall not be construed as a waiver or
relinquishment to any extent of such Party's right to assert or rely upon any
such provision or right in that or any other instance; rather, the same shall be
and remain in full force and effect.

8.6    Return of Information.  Upon the expiration or termination of this
       ---------------------
Agreement, each Party shall, upon the written request of the other Party, return

                                   EXHIBIT C
                                   ---------


                              Operating Standards
                              -------------------


1.     Performance Standards. Company will operate and manage the AOL PMR
Service and the PMR Service so that they each will continue to be competitive at
all times (in terms of, among other things, features, functionality, and breadth
and depth of services) with the top * * * then-current market leaders in the
United States, in aggregate personal medical records services, as determined by
each of the following methods: (a) a cross-section of third party reviewers who
are recognized authorities in the field; and (b) with respect to all material
quality averages in such field, including each of: (i) pricing of Products; (ii)
performance in technical and functional terms, including range and speed of
features and functionality and performance; (iii) scope and selection of
Products; (iii) quality of Products; (iv) customer service and fulfillment; (v)
accuracy and timeliness of Content, including regularity and thoroughness of
updating of Content (including, in particular, time sensitive Content); and (vi)
ease of use. In addition, the PMR Service will be competitive in all material
respects with those services offered by competitors of the PMR Service,
including the performance and availability of similar sites based on similar
technology. For each of the above, Company shall not be responsible for any
failure to remain competitive under such criteria where such failure is
attributable to requirements of, or features or functionality requested by, AOL
under this Agreement (not in any event relating to scalability - it being
understood that Company is required to assure performance on a fully scalable
basis). Company will perform its management obligations hereunder in a timely
and professional manner and in accordance with the terms of this Agreement.
Company will ensure that the PMR Service is current and well-organized at all
times. Company will cause the PMR Service to operate in substantial conformance
with any specifications therefore agreed upon by the Parties for the duration of
the Term, including the initial specifications agreed to pursuant to the
Development Plan.

2.     Added Features.  After the initial development of the PMR Service and the
       --------------
AOL PMR Service, Company will offer to add to the PMR Service and AOL PMR
Service all features and functionality, data and other Content directly related
to, or part of, a personal medical records service: (a) which is available on
the Dr. Koop Site or any other Company Internet Site or (b) is provided by
Company to any third party for use on any other Interactive Site; and/or (c)
otherwise so that the PMR Service complies with these Operating Standards. Such
additional features and functionality and Content described will be made
available to the PMR Service and the AOL PMR Service promptly and no later than
concurrently with the release of such features and functionality by Company for
any alternative use.

3.     Hosting; Capacity. Company will or be responsible for all computer
       -----------------
hardware (e.g., servers, routers, network devices, switches and associated
hardware) in an amount reasonably necessary to meet anticipated traffic demands,
adequate power supply (including generator back-up) and HVAC, adequate
insurance, adequate service contracts and all necessary equipment racks, floor
space, network cabling and power distribution to support the PMR Service and the
AOL PMR Service. Company is fully responsible for the maintenance and the
day-to-day operation of the PMR Service and AOL PMR Service implementations.
Company will provide AOL with a detailed Network diagram. In addition, Company
will provide AOL with detailed information regarding separate file downloads
available from the PMR Service and the AOL PMR Service, which files are of a
large enough size that they could materially impact the AOL technical network,
if any, including file size, type and download/installation procedures.

4.     Speed; Accessibility.  Company will ensure that the performance and
       --------------------
availability of the PMR Service and of the AOL PMR Service is each monitored on
a * * * basis. Company will use commercially reasonable efforts to ensure that:
(a) the functionality and features within the AOL PMR Service are optimized for
the client software then in use by AOL Customers; and (b) the AOL PMR Service is
designed and populated in a manner that minimizes delays when AOL Customers
attempt to access such site.  At a minimum, Company will ensure that AOL PMR
Service data transfer initiates within fewer than * * * on average.

5.     Performance Testing.  Prior to launch of any promotions described herein,
       -------------------
Company will permit AOL to conduct, in a coordinated fashion with Company,
performance and/or load testing of the AOL PMR Service until AOL is reasonably
satisfied that launch can occur, to include but not be limited to the following:

       (a)   AOL Compatibility Testing to ensure that the Company's product
meets the compatibility standards specified in this Exhibit;

       (b)   Network Bandwidth Load Testing as specified in this Exhibit;

                              Exhibit C - Page 1
<PAGE>

       (c)   Network/Web Site Architecture as specified in this Exhibit; and

       (d)  Encryption Methodology

6.     Service Level Response.  Company agrees to use commercial best efforts to
       ----------------------
provide the following service levels in response to problems with or
improvements to the PMR Service and the AOL PMR Service:

       (a)   For material functions of software that are or have become
substantially inoperable (e.g., inability to access website or conduct
transactions), Company will respond within * * * and provide a bug fix or
workaround within * * * after the first report of such error.

       (b)   For functions of the software that are impaired or otherwise fail
to operate in accordance with agreed upon specifications (e.g., search engine),
Company will provide a bug fix or workaround within * * * after the first report
of such error.

       (c)   For errors disabling only certain non-essential functions (e.g.,
broken Links or non-critical applications), Company will provide a bug fix or
workaround within * * * after the first report of such error.

       (d)   For all other errors, Company will address these requests on a
case-by-case basis as soon as reasonably feasible.

7.     Monitoring.  The parties will mutually develop detailed escalation
       ----------
procedures for Company (e.g., contact names and notification mechanisms such as
email, phone, page, etc.) and for notification of AOL by Company of any
scheduled or unscheduled downtimes.  In the event of any performance malfunction
or other emergency related to the PMR Service or the AOL PMR Service, Company
will keep AOL reasonably informed regarding such malfunction or emergency and
Company's efforts to remedy the situation and will comply with AOL's reasonable
response requirements.  The parties will develop in consultation with each other
a process to monitor performance and member behavior with respect to access,
capacity, security and related issues both during normal operations and during
special promotions/events.  Such process will require that Company keep AOL
reasonably informed regarding the results of such monitoring.

8.     Telecommunications. The Parties will agree on a plan for Company to
       ------------------
provide encryption methodology to secure data between the Parties' data centers.
The network between Company and the Internet will be configured such that no
single component failure will significantly impact AOL Customers. The network
between Company and the Internet will be sized such that no single line runs at
more than * * * average utilization for a 5-minute peak in a daily period.

9.     Security Review. Company and AOL will work together to perform an initial
       ---------------
security review of, and to perform tests of, the Company system, network, and
service security in order to evaluate the security risks and provide
recommendations to Company, including periodic follow-up reviews as reasonably
required by Company or AOL.  Company will use commercially reasonable best
efforts to fix any security risks or breaches of security as may be identified
by AOL's Operations Security.  Specific services to be performed on behalf of
AOL's Operations Security team will be as determined by AOL in its reasonable
discretion.

10.    Technical Performance.  Company will perform the following technical
       ---------------------
obligations (and any reasonable updates thereto from time to time by AOL):

       .     Company will design the PMR Service to support the following
             browsers and platforms: MSIE 3.0 (Windows 3.1, Win95 and 98 & Mac);
             MSIE 3.0 (Mac); MSIE 4.0 (Win 3.1, Win95 & 98 and Mac); MSIE 5.0
             (Win 3.1, Win 95 & 98 and Mac) Netscape 3.0 (Win 3.1, Win95 & 98 &
             Mac); Netscape 4.0 (Win 3.1, Win95 & 98 & Mac); Netscape 5.0 (Win
             3.1, Win 95 & 98 & Mac); AOL 3.0 - 16bit and 32bit on PC; AOL 3.0
             on Mac; AOL 4.0 on PC and Mac; and make commercially reasonable
             efforts to support all other AOL browsers listed at:
             "http://webmaster.info.aol.com."

       .     Company will configure the server from which it serves the site to
             examine the HTTP User-Agent field in order to identify the "AOL
             Member-Agents" listed at: "http://webmaster.
             info.aol.com/Brow2Text.html."

       .     Company will design its site to support HTTP 1.0 or a backward
             compatible later protocol as defined in RFC 1945 (available at
             "http://ds.internic.net/rfc/rfc1945.text") and to adhere to AOL's
             parameters for refreshing cached information listed at
             http://webmaster.info.aol.com/CacheText.html.
             --------------------------------------------

11.    AOL Internet Services Partner Support.  AOL will provide Company with
       -------------------------------------
access to the standard online resources, standards and guidelines documentation,
technical phone support, monitoring and after-hours assistance that AOL makes

<PAGE>

any technologies, databases, software or other applications which are not
supported by AOL or are related to any Company area other than the PMR Service.
Support to be provided by AOL is contingent on Company providing to AOL demo
account information (where applicable), a detailed description of the PMR
Service' software, hardware and network architecture and access to the PMR
Service for purposes of such performance and load testing as AOL elects to
conduct. Company will remain responsible to ensure that the PMR Service
satisfies the specified access and performance requirements as outlined in this
Exhibit.

12.  Subcontracting.  Company may subcontract with others to services required
     --------------
of Company hereunder, subject to AOL's consent, not to be unreasonably withheld
or delayed.  Company will remain primarily responsible for the performance of
such third parties in conformance with the requirements of this Agreement.
Without limiting the foregoing, Company will be fully responsible for the
performance and scalability of its subcontractors'  platforms, as well as the
interconnectivity between Company and those subcontractors (e.g., OFX Adapter
Layer).  Company will use commercially reasonable efforts to have the PMR
Service provide AOL a mechanism for AOL to interact with such third parties on
operational and other issues relating to the PMR Service.  In addition, if AOL
believes any such third party is not performing as required by this Agreement,
Company will cause the correction of such performance, or, if requested by AOL,
the termination of the relationship as it relates to the PMR Service.  Company
will be responsible for negotiations and account management with Third Party
Service Providers.

13.  Obligation.  Except as otherwise expressly set forth in this Agreement, as
     ----------
between the parties Company will be responsible for all aspects of the
performance of the PMR Service, including security (such as SSL encryption) and
compliance of the PMR Service with all specifications.

14.  Alternative Sites.  Company will maintain the AOL PMR Service as a separate
     -----------------
site from any other site so that all users are AOL PMR Users.  Company will not
take or omit to take any action in its provision of the AOL PMR Service that
would direct users to, or enhance or promote the possibility that users of the
AOL PMR Service would enter or use, another service or Product competitive with
or similar to the PMR Service or any Product thereon, including any Company
Internet Site.  Without limiting the foregoing, Company will not direct
promotions to AOL PMR Users or third parties that promote any other such service
or Product.

15.  Problem Resolution. Company agrees to use commercially reasonable efforts
     ------------------
to provide the following service levels in response to problems with the PMR
Service:

       .  For material functions of the PMR Service that have become inoperable,

          within * * * after Company's receipt of the first report of such
          error.

       .  For other functions of the PMR Service that are impaired or otherwise
          fail to operate in accordance with agreed upon specifications, Company
          will provide a bug fix or workaround within * * * after the first
          report of such error.

       .  For all other problems with the functionality or performance of the
          PMR Service, Company will use commercially reasonable efforts to fix
          such problems within * * * after the first report of such problems, or
          if not reasonably practicable, as soon as reasonably feasible.

For any problem that is not, or reasonably cannot be, resolved within the above
time frames, Company shall provide AOL with prompt notice of Company's inability
to timely remedy such problem.
