          ACTIVITIES, RESPONSIBILITIES AND COMPENSATION OF THE PARTIES

2.1 RESPONSIBILITIES OF THE PARTIES - GENERAL:

2.1.1                  The Venture is a cooperative venture whose success
                       depends on each of the Parties performing the tasks
                       for which it is responsible under this Article 2, and
                       each Party shall render all services to be provided
                       hereunder to Clients in a competent and workmanlike
                       manner.

2.1.2                  Livewire and HTVN will each be solely responsible
                       for establishing the terms and conditions on which
                       they will provide to Clients, directly or through the
                       Company, the services to be provided by such Parties
                       in connection with this Agreement, including the fees
                       and expenses to be charged by such Parties for such
                       services. Subject to the first sentence of this
                       Section 2.1.2, the Parties shall actively consult
                       with one another and

                       cooperate in good faith to coordinate such terms,
                       conditions, fees and expenses, with the goal of
                       maximizing the success of the Venture.

2.2     THE COMPANY:

2.2.1                  The Company is intended to be the primary sales and
                       billing entity for HyperTV Technology and will
                       coordinate and manage the marketing and sale of
                       HyperTV Technology in the Field of Use.

2.2.2                  The Company will use commercially reasonable efforts
                       to diligently and actively develop, promote, market
                       and sell products and services incorporating the
                       HyperTV Technology in agreed upon markets, in
                       accordance with and subject to the limitations set
                       forth in this Agreement.

2.2.3                  Clients will have the opportunity to purchase
                       Authoring Services, Hosting Services, use of the
                       HyperTV Technology, e-commerce and advertising
                       enabling, data management services and any other
                       services offered by or through the Company from time
                       to time on either a bundled or "a la carte" basis,
                       with the aggregate fees and expenses for such
                       services quoted and billed by the Company on such
                       basis as the Company shall determine from time to
                       time to be appropriate (including, where the Company
                       determines appropriate, single price or "all-in"
                       pricing for the services purchased). Such services
                       will be provided by Livewire and HTVN as provided for
                       in this Agreement.

2.2.4                  The Company will (a) pay Livewire and HTVN a fee
                       determined pursuant to Section 2.1.2 for all services
                       provided by Livewire and HTVN through the Company or
                       (b) allocate and remit to Livewire and HTVN,
                       respectively, the fees collected by the Company for
                       such services from Clients, in each case in
                       accordance with procedures established by the Company
                       from time to time and approved in writing by Livewire
                       and HTVN (which approval will not be unreasonably
                       withheld or delayed). The Company shall not retain
                       any fees and expenses collected from Clients, except
                       by the mutual consent of the Parties.

2.2.5                  The Parties will work together to minimize
                       expenditures at the Company level, and, to that end,
                       the Company will have limited personnel, if any. HTVN
                       and Livewire will make available to the Company, on a
                       fair and commercially reasonable basis, marketing and
                       sales personnel as well as personnel to perform
                       administrative and bookkeeping functions. If the
                       Parties determine that the Company needs to have its
                       own personnel, they will mutually agree on a budget
                       for such personnel. Neither HTVN nor Livewire will
                       authorize any expenditures by the Company, or for
                       which the Company may be liable, without the prior
                       written consent of the other (which consent shall not
                       be unreasonably withheld or delayed), or in
                       accordance with a budget approved in writing by both
                       Parties.

2.2.6                  Initially, the Company will focus its sales and
                       marketing efforts on the United States and Europe,
                       and will expand into other markets upon the mutual
                       agreement of the Parties, which agreement shall not
                       be unreasonably withheld or delayed.

2.2.7                  HTVN and Livewire shall each own fifty percent (50%)
                       of the equity interests and voting power of the
                       Company and shall each appoint an equal number of
                       representatives to the managing body of the Company.
                       The Company's managing body will initially consist of
                       Bruce Crowley and Bill Airy, representing HTVN and
                       Livewire, respectively.

2.2.8                  The Company shall provide to both HTVN and Livewire
                       all financial statements and reports of the Company
                       necessary to allow HTVN and Livewire and their
                       Affiliates to make their required Securities and
                       Exchange Commission filings in a timely fashion.

2.3     LIVEWIRE:

         Livewire will be responsible for, and will derive Revenue from, the
         following activities:

2.3.1                  Livewire shall provide distribution and Hosting
                       Services to Clients at facilities operated or
                       contracted for by Livewire from time to time, and
                       shall have the exclusive right to provide such
                       services to third parties in the Field of Use.
                       Livewire's right of exclusivity for distribution and
                       Hosting Services shall not preclude any Client or its
                       Affiliate from performing its own distribution and
                       Hosting Services for HyperTV Distributed Community
                       Networks, utilizing primarily its own personnel,
                       through facilities owned and operated by such Client
                       or Affiliate. If HTVN or the Company license the
                       HyperTV Technology to any person outside the Field of
                       Use and such person does not intend to provide its
                       own Hosting Services, HTVN or the Company, as
                       applicable, shall use commercially reasonable efforts
                       to provide Livewire with an opportunity to bid on the
                       provision of such services.

2.3.2                  Livewire shall provide Event Broadcast Services and
                       Technical Quality Control Services to Clients using
                       qualified personnel at facilities operated by or
                       contracted for by Livewire from time to time, and
                       shall have the exclusive right to provide such
                       services; provided, that, during the transition
                       period, HTVN shall provide such services concurrently
                       with Livewire and cooperate with Livewire to provide
                       the training and technology support necessary for
                       Livewire to provide such services after such
                       transition period.

2.3.3                  Livewire shall provide Authoring Services to Clients,
                       and shall have the exclusive right to provide such
                       services in the Field of Use, except as provided in
                       the following two sentences. Livewire's right of
                       exclusivity for Authoring Services shall not preclude
                       any Client or its Affiliate from

                                        9


<PAGE>

                       performing its own Authoring Services for HyperTV
                       Distributed Community Networks, utilizing primarily
                       its own personnel, through facilities owned and
                       operated by such Client or Affiliate. In addition HTVN
                       will have the right to provide Authoring Services, (i)
                       outside the Field of Use and (ii) on a limited basis,
                       in the Field of Use, as mutually agreed upon by the
                       Parties. In the event Livewire chooses not to provide
                       Authoring Services to certain Clients, HTVN may, in
                       its own discretion, provide Authoring Services to such
                       Clients.

2.3.4                  Livewire may from time to time provide Authoring
                       Services, Hosting Services and other services
                       relating to HyperTV to Clients in conjunction with
                       Livewire's general production, post-production,
                       transmission, archiving and related services. In that
                       connection, the Company may from time to time
                       authorize Livewire to provide the HyperTV Technology
                       to Livewire's clients, on behalf of the Company, on
                       such basis as the Company shall determine to be
                       appropriate. In such event, Livewire will collect the
                       HyperTV Technology License Fee on behalf of the
                       Company and remit such fee to HTVN in accordance with
                       procedures established for such circumstances by the
                       Company. The Company may from time to time authorize
                       HTVN to provide e-commerce enabling, advertising
                       enabling and data management services (excluding
                       Hosting Services and Authoring Services) to the
                       Company's clients, on behalf of the Company, on such
                       basis as the Company shall determine to be
                       appropriate.

2.3.5                  With respect to the provision of Hosting Services,
                       Livewire will use commercially reasonable efforts to
                       support a minimum of one million (1,000,000)
                       concurrent users in one or more data centers by
                       September 30, 2000.

2.4     HTVN:

        HTVN will be responsible for, and will derive Revenue from the
        following:

2.4.1                  The HyperTV Technology License Fee, which may be
                       expressed as a separate line item or may be bundled
                       into the services provided by the Parties.

2.4.2                  e-commerce enabling such as striping, encoding,
                       filtering, targeting, technical integration,
                       transactional quality control, reporting
                       click-through and associated data and fulfillment.

2.4.3                  Advertising enabling such as striping, encoding,
                       inserting, filtering, targeting, sequencing,
                       reporting click-through and associated data,
                       permission based marketing and fulfillment.

2.4.4                  Data management services.

                           Technical Quality Control Services during the
                           transition period.

2.4.6                      HTVN shall maintain and develop ongoing Improvements
                           to the HyperTV Technology, including software
                           updates, revisions and modifications thereto, as HTVN
                           and/or the Company shall reasonably request.

2.4.7                      HTVN shall have the responsibility to defend the
                           HyperTV Technology against infringements or
                           violations. In general, upon the discovery of any
                           infringement of the HyperTV Technology, HTVN shall
                           have the sole right to take appropriate action to
                           suppress such infringement, including the sole right
                           to determine whether or not any action shall be taken
                           on account of such infringement or violation of the
                           HyperTV Technology, and the right to negotiate and
                           enter into a pre-litigation or pending-litigation
                           settlement with the identified infringer and HTVN
                           shall receive any sums recovered in such suits or
                           settlements. Any such settlement by HTVN may include
                           the grant of a non-exclusive license to use all or
                           part of the HyperTV Technology PROVIDED that no such
                           license shall conflict with or limit in any material
                           respect Livewire's rights of exclusivity
                           with respect to the provision of Authoring Services
                           and Hosting Services in the Field of Use without the
                           prior written consent of Livewire, which consent
                           shall not be unreasonably withheld or delayed.

                           HTVN shall from time to time consult with Livewire in
                           good faith with respect to any infringements and
                           violations, and if Livewire so requests, will provide
                           Livewire with a reasonable opportunity to join HTVN
                           in any action to suppress such infringements or
                           violations near the onset of such suits, provided
                           that in such event all costs, expenses, and attorneys
                           fees incurred shall be shared equally between the
                           Parties herein and neither Party shall settle any
                           such action without the consent of the other, which
                           consent shall not be unreasonably withheld or
                           delayed. In such a jointly prosecuted suit, any sums
                           recovered in the suit or in settlement thereof shall
                           be used, first, to pay any outstanding bills for
                           expenses arising from the prosecution and any
                           settlement of the suit, and to reimburse the Parties
                           herein for their contributions to such expenses; and,
                           then, any remainder shall be shared by the Parties.

                      applicable to its business, except as otherwise

                      United States Securities and Exchange Commission by
                      ACTV and/or HTVN since December 31, 1998 and a true,
                      correct and complete copy of the License Agreement

                      the rights, titles and interests that are necessary
                      for the grant of the use licenses provided in this
                      Agreement and the Company/Livewire License. The
                      business of HTVN is being carried out without, to the
                      knowledge of HTVN, conflict with any U.S. patents,
                      licenses, trademarks, copyrights, trade names and
                      trade secrets of any other persons.

                      To the best knowledge of HTVN, no interferences,

                      Trademark Office with respect to any of the patent or
                      patent applications listed in Exhibit B. No statutory
                      disclaimers were filed within the United States
                      Patent and Trademark Office with respect to any of
                      the patent or patent applications listed in Exhibit
                      B, other than any terminal disclaimers that would not
                      result in any such patent expiring prior to the 20th
                      anniversary of the earliest priority date applicable
                      to any of the patents and patent applications listed
                      in Exhibit B.

                      HTVN shall indemnify Livewire from and against all
                      liabilities or losses, including without limitation
                      reasonable attorneys' fees, arising out of any final
                      non-appealable judgment by a U.S. court of competent
                      jurisdiction ("Judgment") to the effect that the use
                      of the HyperTV Technology alone by the Company or
                      Livewire in accordance with this Agreement violates
                      or infringes any valid and enforceable U.S. patent,
                      copyright, trade secret or other intellectual
                      property right of any other person existing on the
                      date of this Agreement, without regard to the
                      knowledge of HTVN, or conflicts with any license
                      heretofore granted by HTVN or any of its predecessors
                      or Affiliates; PROVIDED, HOWEVER, that (i) the
                      aggregate liability of HTVN to Livewire under this
                      sentence shall in no event exceed the value of the
                      Warrant paid by HTVN at the date of the Judgment,
                      plus any appreciation theretofore realized or accrued
                      by HTVN in respect of shares acquired upon exercise
                      of the Warrant (determined on an after tax basis, if
                      applicable), and (ii) if HTVN shall have any
                      liability to Livewire under this sentence, HTVN shall
                      have the right to satisfy that liability in whole or
                      in party by (A) canceling Share Purchase Rights (as
                      defined in the Warrant) and/or (B) surrendering
                      shares of common stock acquired upon exercise of the
                      Warrant, in either case having an aggregate value at
                      the date of such Judgment equal to such liability of
                      HTVN hereunder.

                       ADDITIONAL COVENANTS OF THE PARTIES

5.1      ADDITIONAL DVD REVENUE OPPORTUNITIES: In the event that any application
         of the HyperTV Technology for use with DVDs results in incremental
         revenue opportunities not contemplated by this Agreement (i.e. revenue
         opportunities not related to Authoring Services, Hosting Services and
         DVD mastering services for Livewire, or the HyperTV Technology License
         Fee, e-commerce and advertising enabling, and data management services
         for HTVN), the Parties shall negotiate reasonably and in good faith
         with respect to the apportionment of such additional DVD revenue
         opportunities and the associated responsibilities. Notwithstanding the
         foregoing, the Parties acknowledge and agree that HTVN is required to
         obtain approval from Thomas R. Wolzein with respect to applications of
         the HyperTV Technology for use with DVDs pursuant to the Assignment
         Purchase Agreement dated April 7, 1999 by and among Thomas R. Wolzein
         and Media Online Services, Inc.

5.2      PROVISION OF COMPETITIVE SERVICES: HTVN and Livewire acknowledge that
         either HTVN and/or Livewire may from time to time market and provide
         other products and services to third parties generally in the
         interactive TV and convergence field, some of which may be
         complementary to the HyperTV Technology. Livewire will not, however,
         sell any services that infringe upon or violate in any material respect
         any intellectual property rights of HTVN in the HyperTV Technology.

5.3      ADDITIONAL SERVICES TO THE COMPANY: In the event that either Party
         agrees to provide any services to the Company in addition to the
         specific responsibilities provided for herein, such Party shall be
         entitled to fair and equitable compensation therefor, as negotiated by
         the Parties reasonably and in good faith.

5.4      BUSINESS OPPORTUNITIES: Nothing herein shall prevent either HTVN or
         Livewire from taking advantage of any other business opportunities that
         may become available to such Party from time to time during the term of
         this Agreement, or require either such Party to offer any such business
         opportunity to the Company or the other Party.

         permitted hereunder or cause, enable, assist or permit anyone else to
         utilize any of the HyperTV Technology, Improvements and/or related
         information (the "Confidential Information,") which is not generally
         available to the public unless: (i) through no act of such party

         Information becomes known to the public prior to the date of such Party
         disclosure; (ii) such Confidential Information is approved for public
         release by HTVN; (iii) such Confidential Information is rightfully
         received by such Party from a third party without restrictions and
         without breach of such Party's obligations hereunder; (iv) such
         Confidential Information is independently developed by such Party
         without breach of this Agreement, and such Party can so demonstrate by
         a preponderance of the evidence; or (v) such Confidential Information
         is required to be disclosed by judicial or governmental proceeding.

         Notwithstanding the foregoing, such Party may disclose such
         Confidential Information to its employees who need to know such
         information in order to use and exploit the HyperTV Technology pursuant
         to the terms of this Agreement if it has taken reasonable steps to
         impose the aforesaid covenants of confidentiality on said employees and
         to ensure that said employees will not violate said covenants,
         including but not limited to, causing said employees to enter into
         written agreements in which said covenants of confidentiality are
         effectively imposed upon them. Each Party will copy the Confidential
         Information only to the extent reasonably necessary to enable each
         party to exercise its rights hereunder. In making any such copies, each
         Party agrees to reproduce faithfully all notices respecting copyright,
         trade secrets, and other proprietary rights. Nothing contained herein
         shall prevent each Party from disclosing in general terms the nature of
         its relationship with HTVN.

5.6      PURSUIT OF RIGHTS: In the event a Client is in default of its
         obligations under this Agreement, either Party may pursue its rights
         with respect to such Client independently of the other Party.

5.7      DELIVERY OF BILLS: Whenever HTVN or Livewire shall individually bill
         any Client, each Party shall thereupon provide copies of such bill to
         the other Party.

                                    ARTICLE 6
              DISPOSITION OF THE PARTIES' INTERESTS IN THE COMPANY

Agreement, engage in any sale, assignment or transfer or any other disposition
of any or all of its interest in the Company, including, without limitation, by
means of any pledge, hypothecation, mortgage, lien or encumbrance, without the
consent of the other Party, except that (i) Livewire will have the right to
assign or otherwise transfer its rights in the Company and/or its rights under
this Agreement to any Affiliate of Liberty Media Corporation or any Affiliate of
the entity that survives the pending acquisition of Todd by an Affiliate of

During the term of this Agreement, each of the Parties shall maintain, at its

within six (6) months prior to such solicitation or hiring. The Parties
acknowledge that a violation of this paragraph could cause irreparable harm to
