        Members. The Co-Branded Application will include offers and other
        content and functionality (Excite Content and e-centives Content,
        collectively "Application Content") as further described in EXHIBIT B.

     b) Application Provider will design and create web pages containing the
        Application Content ("Application Pages"). The Application Pages will be
        presented in accordance with guidelines that Excite@Home will provide
        Application Provider, which include, but are not limited to, page
        performance standards and header and other design/user interface
        standards. The Application Pages will prominently feature Excite@Home
        branding and will be presented in a "look and feel" consistent with the
        "look and feel" of the Excite Network. Excite@Home will have final
        approval over all Application Pages. The Application Pages shall be
        developed in accordance, in all material respects, with the requirements
        established by EXHIBIT B.

     c) Application Provider will develop its category/directory structures to
        be similar to those found on the Excite@Home Network and in accordance
        with the requirements established by EXHIBIT B, SECTION 4.

     d) Application Provider will host the Co-Branded Application on its
        Internet servers, but will serve the Co-Branded Application from an
        "excite.com" masked domain name (or such other domain as Excite@Home may
        elect at its sole option) so that Excite@Home can receive the reach and
        page view credit. Application Provider will have sole responsibility for
        providing and maintaining, at its expense, the Application Provider
        Site, the Co-Branded Application, the Application Content (excluding the
        provision of Excite Content), and any updates thereto.

     e) Each Co-Branded Page will include one or more links to the Excite
        Network, as set forth in Section 3(d). Excite@Home will supply
        Application Provider with the URLs for these links.

     f) Other than updates to the Application Content and to advertising
        displayed on the Application Pages, Application Provider will not change
        the Co-Branded Application without Excite@Home's prior consent, which
        consent will not be unreasonably withheld. Excite@Home will respond to
        change requests within seven (7) days of receipt, and any failure to so
        respond shall be deemed an approval.

     g) Excite@Home may, upon fifteen (15) days prior notice to Application
        Provider, request reasonable revisions to the Co-Branded Application as
        needed to reflect changes that will not adversely affect Application
        Provider, such as changes to Excite@Home's name and/or brand or changes
        to the URLs for the links to the Excite Network. Application Provider
        will use reasonable efforts to accommodate Excite@Home's requested
        changes within the fifteen (15) day period.

     h)   Excite@Home will have editorial control over all email or other
          similar communication with Excite@Home Members. Correspondence solely
          regarding the Co-Branded Application will only be presented to Program
          Members; communication with all other Excite@Home Members will be tied
          to regular Excite@Home email schedules, which may or may not be
          integrated with other email content at Excite@Home's sole option.
          Correspondence specific to the Co-Branded Application may be mailed on
          a schedule independent of other Excite@Home member mailings for those
          Qualified Program Members that specify a frequency of contact. Until
          an individual General Program Member specifies a frequency of email
          contact, he or she will by default receive email pursuant to the
          Co-branded Application's every-other-week email option setting. Any
          mailings to such General Program Members who have not specified a
          frequency of email contact will be mailed on a schedule that
          coordinates contact with other Excite@Home newsletter and promotional
          contacts, but at least with the frequency of every-other-week.
          Communications with Excite@Home Members shall further be subject to
          the requirements of EXHIBIT D.

3.   INTEGRATION WITH EXCITE@HOME SERVICES

     a)   Application Provider will integrate the Co-Branded Application with
          Excite@Home's Universal Registration System ("URS") according to
          Excite@Home's technical and operational specifications. Each party
          will incur their own costs related to the integration.

     b)   Information collected through the Co-Branded Application will include,
          but not be limited to,

          i)   URS User Data, whose categories may be modified from time to time
               at Excite@Home's sole option;

          ii)  Superset Data, whose categories shall be determined by mutual
               agreement but subject to Excite@Home's final approval;

          iii) Shopping Category Data, whose contents shall be determined by
               mutual agreement but subject to Excite@Home's final approval.

     c)   All Information collected under this Agreement will be transmitted
          between the parties in a manner to be mutually agreed upon.

     d)   The Co-Branded Application will include content with links that direct
          Users to other Excite@Home content, including but not limited to
          community products, which include message boards, chat, clubs, home
          pages, instant messaging, calendar, address book, email, photos and
          any other community products which Excite@Home may develop during the
          term of this Agreement ("Community Products"). The number of links to
          other Excite@Home content shall be consistent with the general
          quantity of links implemented on comparable portions of the Excite
          Network.

        Application Provider will not feature non-Excite@Home Community Products
        on the Co-Branded Application without the written permission of
        Excite@Home.

     e) Application Provider will publish to Excite@Home subsets of its content
        in a mutually-agreed XML or pre-defined text format (e.g. URL's
        captions, brief two-sentence descriptions, news headlines, pointers into
        longer descriptions, and abstracts) in order for Excite@Home to
        integrate, at its option, portions of the content into its search
        results, directory results and other areas of Excite@Home in order to
        drive traffic to the Co-Branded Application, as deemed appropriate by
        Excite@Home in its sole discretion. Neither party will export to the
        other party any licensed third-party data for which the providing party
        does not have redistribution rights.

     f) Application Provider will provide and regularly update database mappings
        necessary to maximize search and directory integration for the
        Co-Branded Application into Excite@Home's services.

     g) Application Provider will provide Excite@Home with a regularly updated
        data feed of product information for integration into Excite@Home's
        commerce services. The data feed will be provided according to
        Excite@Home's then-applicable standard product data import
        specifications, which specifications shall be substantially similar to
        those required by similar service providers in the industry.

     h) Excite@Home will provide Application Provider with a regularly updated
        data feed of product information for integration into the Co-Branded
        Application. The data feed will be provided according to Excite@Home's
        standard product data export specifications, which specifications shall
        be substantially similar to those required by similar service providers
        in the industry.

     i) Excite@Home shall not offer any Excite-branded or Excite-co-branded
        service during the Term of this Agreement that is substantially similar
        in functionally to the Co-Branded Application.

4.   ADVERTISING ON THE CO-BRANDED APPLICATION

     a) Excite@Home will have the right to sell and serve Excite banner,
        sponsorship, and text link advertising on the Co-Branded Application, as
        limited by the terms of this Section. Excite@Home will have the right to
        sell and serve such advertising on all pages within the Co-Branded
        Application. Revenues from such advertising shall accrue wholly to
        Excite@Home. Application Provider will enable the ad-serving and
        accommodate Excite@Home's technical requirements, which shall be

     consistent with those of Excite's other partners and the standards
     generally used in the industry, at its own expense.

b)   Banner advertising shall be limited to one standard-size banner below
     the Co-Branded Application's content area, as described in Section 2.

c)   Sponsorship modules will be present on the Co-Branded Application in a
     quantity consistent with the overall quantity within other shopping
     content areas of Excite. Each party shall have the right to sell and
     serve advertisements on 50% of the sponsorship tiles within the Co-Branded
     Application. As of the Effective Date of this Agreement, pages within
     Excite@Home's shopping service contain four sponsorship tiles arranged
     vertically on the right hand side of each page, though over time this may
     change at Excite@Home's sole option, but such changes shall not conflict
     with Application Provider's contractual obligations. Within this
     framework, Application Provider will have access to the first and third
     tiles from the top; Excite@Home will have access to the second and fourth
     tiles. Should additional tiles be added during the term of this Agreement,
     the first incremental tile shall be allocated to Application Provider, the
     following to Excite@Home, and so forth. Revenue generated by the parties
     from such activities shall not be shared but rather shall be retained by

          previously submitted a General Program Member User Data record, the
          record shall be accounted for as follows:

          (1)  If the Qualified Program Member User Data record is supplied in
               the same quarter in which the General Program Member User Data
               record was originally supplied to e-centives, the Program Member
               record shall be treated as always having been a Qualified Program
               Member record for purposes of both volume and payments.

          (2)  If the Qualified Program Member User Data record is supplied in a
               quarter different from the one in which the General Program
               Member User Data record was originally supplied to e-centives,
               the Program Member record shall be treated as a Qualified Program
               Member record for purposes of both volume and payments, but a
               credit shall be applied against the General Program Member volume
               and payment guarantees.

          (3)  Payments shall be based upon the total number of records
               delivered for each Program Member category. For payment purposes,
               Excite@Home shall be obligated to track only total records per
               category and shall not be obligated to track individual records.

d)   Payment Schedule

     i)   Within ten (10) days of the Effective Date of this Agreement,
          e-centives shall make a non-refundable payment to Excite@Home of
          $***** as pre-payment for Payment-Eligible User Data records:

          (1)  e-centives will pay Excite@Home $***** in pre-payments for
               ***** General Program Member User Data records.

          (2)  e-centives will pay Excite@Home $***** in pre-payments for

     ii)  During the Term of this Agreement, on the first day of each quarter
          following the quarter in which the Launch Date falls, e-centives shall
          make additional non-refundable payments for the Payment-Eligible User
          Data records. In the event that the Launch Date is delayed beyond
          March 31, 2000, the April 1, 2000, payment pursuant to this subsection
          shall be postponed and shall instead be made within (10) days of the
          Launch Date. Payments under this subsection shall be calculated as
          follows:

               (1)  General Program Member User Data: $*****, plus $*****
                    times the total number of records previously delivered, less
                    all amounts previously paid on account of General Program
                    Member User Data.

               (2)  Qualified Program Member User Data: $*****, plus $*****
                    times the total number of records previously delivered, less
                    all amounts previously paid on account of General Program
                    Member User Data.

          iii) The amounts paid pursuant to subsection 7.d.ii shall be further
               subject to the following cap: at no point shall e-centives' total
               payments exceed an average of $***** per quarter. In the
               event that the payment amount dictated by the formulas in
               subsections 7.d.ii.(1) and (2) would raise e-centives' total
               payments to an average in excess of $***** per quarter,
               e-centives shall instead pay only that amount necessary to
               maintain an average quarterly payment of $*****.

          iv)  A sample hypothetical payment schedule showing the effect of this
               provision is included solely for purposes of illustration in
               EXHIBIT G.

     e)   In the event that Excite@Home delivers more than *****
          Payment-Eligible General Program Member User Data records and/or more
          than ***** Payment-Eligible Qualified Program Member User Data
          records during the Term of the Agreement, e-centives will pay
          Excite@Home, on a quarterly basis, *****% of net revenue (gross
          revenue less direct third party commissions) generated from the
          delivery of offers to any such excess Program Members. This provision
          shall apply to net revenue generated during the year following the
          end of the calendar quarter in which the names were supplied,
          irrespective of the Term of this Agreement.

8.   USER DATA DELIVERY PERFORMANCE MEETINGS

          Excite@Home's sole discretion. Such e-centive packages shall be

          that Excite@Home elects in its sole discretion to purchase in excess
          of $***** in e-centive packages during any quarter, any such excess
          purchases shall constitute a credit which Excite@Home may apply
          against its minimum purchase obligations in any subsequent quarter(s).

     b)   Excite@Home will determine, at its sole discretion, the size and
          nature of each e-centive package bought under these terms.

     d)   e-centives may not extend exclusive offers developed for Excite@Home
          by its advertisers to non-Excite@Home users of the e-centives service
          for a period of 30 days following the day on which the offer is first
          made available through Excite@Home.

     companies is quoted within the release. Both parties will provide

     arrangements contemplated without the other party's written approval prior
     to release. Notwithstanding the foregoing, Excite@Home agrees to allow
     reference to its name and disclosure of the terms of the relationship

     The term of this Agreement will begin on the Effective Date and will end
     three (3) years from the date the Co-Branded Application becomes
     accessible to Excite@Home Members ("Launch Date").

16.  TERMINATION

     a)   Basis for Termination:

          i)   Either party  may terminate if the other party breaches the
               Agreement and the breach remains uncured for thirty (30) days
               following receipt of written notice of intention to terminate
               from the other party.

          ii)  Excite@Home may terminate the Agreement with thirty (30) days
               written notice if Application Provider does not meet the content
               and launch guidelines described in EXHIBIT B.

          iii) Excite@Home may terminate the Agreement if the Co-Branded
               Application is not at least comparable to any other source of
               Application Content on the Internet in accordance with the
               following provisions:

               (1)  At any time during the Term of this Agreement, Excite@Home
                    may determine, in its reasonable judgment, that the
                    Co-Branded Application is not at least comparable to other
                    sources of Application Content generally available on the
                    Internet in terms of the following factors:

been filed separately with the Securities and Exchange Commission.

          (iii) Personalization; and

          (iv)  User interface and ease of use.

     (2)  If Excite@Home determines that the Co-Branded Application is not at
          least comparable to other sources of Application Content generally
          available on the Internet in terms of at least two of the four factors
          in Section 16.a.iii.1, Excite@Home may notify Application Provider in
          writing of said deficiency, which shall initiate a 28-day "Cure
          Period." If at the end of the Cure Period Excite@Home, in its
          reasonable judgment, determines that the deficiency still exists, then
          Excite@Home may terminate the Agreement without further delay.

iv)  Either party may terminate the Agreement without penalty upon thirty (30)
     days' written notice if regulations or applicable laws applied at the US
     federal level regarding privacy or User Data purchase and/or usage impede
     or prohibit said party from performing its services as contemplated by this
     Agreement or thereafter.

v)   In the event that a majority of Application Provider's assets are merged,
     acquired or sold to an Excite@Home Named Competitor, or to an entity
     controlling or controlled by an Excite@Home Named Competitor, then
     Excite@Home may terminate this Agreement by providing thirty (30) days
     written notice. This option to terminate this Agreement may only be
     exercised by providing written notice within ninety (90) days of
     Excite@Home's receiving notice of such transaction. Application Provider
     shall provide such notice at least twenty-four (24) hours before the public
     announcement of any such transaction.

vi)  The parties acknowledge that, due to the continually evolving nature of the
     Internet, substantive changes to the product plan and integration
     contemplated in the Agreement will likely be necessary during the Term.
     From time to time, Excite@Home may require that Application Provider
     provide extensions, incremental services and/or integration of the
     Co-Branded Application (collectively, "Modifications"). In the event that
     Application Provider is unable and/or unwilling to deliver such additions,
     or in the event that the parties disagree on the direction of the
     Co-Branded Application or its integration, Excite@Home may terminate the
     Agreement with no penalty by providing ninety (90) days written notice.
     Notwithstanding the foregoing, Excite shall not be entitled to terminate
     this Agreement in the event that the requested

                                       17

          Modifications exceed or are outside the scope of technology and/or
          service levels generally available on the Internet.

          other party.

     ii)  Each Party will pay all earned and undisputed outstanding amounts owed
          to the other Party under this Agreement within thirty (30) days after
          the effective date of such termination. Notwithstanding the foregoing,
          all payments for User Data records shall be due and accrue in
          accordance with terms of this Agreement.

     iii) For a period of up to sixty (60) days, Application Provider will
          provide consulting services to Excite@Home, as Excite@Home may
          reasonably request and for reasonable fees to be paid to Application
          Provider, such fees to be agreed upon in writing by the Parties, to
          assist Excite@Home in providing a seamless transition to Program
          Members. Application Provider will have no obligation to provide such
          services to Excite@Home to the extent that Application Provider's
          personnel and resources are unavailable in the amounts requested by
          Excite@Home or if the Parties are unable in good faith to agree on the
          reasonable fees to be paid to Application Provider for such services.
          Application Provider will not be required, in the course of providing
          such consulting services to Excite@Home, to disclose or transfer to
          Excite@Home any proprietary information, software, or Intellectual
          Property of Application Provider or any of its merchant partners.

     iv)  To further ensure a seamless transition for Program Members, in the
          event of a termination based upon a material breach by e-centives or
          an acquisition pursuant to Section 16.a.v. only, Application Provider
          shall continue to host and maintain the Co-Branded Application for a
          period of one hundred twenty (120) days following either receipt or
          issuance of notice of intention to terminate this Agreement. Such
          hosting and maintenance of the Co-Branded Application shall be
          provided by Application Provider at such reasonable rates as are
          mutually agreed upon by the parties.

     v)   The provisions of this Section (Termination), Section 17
          (Post-Termination Communications), Section 18 (Confidentiality),
          Section 19 (Warranties and Indemnities), Section 20 (Limitation of
          Liability), and Section 21 (Dispute Resolution) shall survive any
          termination or expiration of this Agreement.

17.  POST-TERMINATION COMMUNICATIONS

     a)   Upon termination of this Agreement for reasons other than a
          relationship with an Excite@Home Named Competitor under Section
          16.a.v., the parties will communicate with Program Members as follows:

          i)   Excite@Home will email Program Members on e-centives' behalf up
               to a maximum of two times. Consistent with other communications
               envisioned during the Term of the Agreement, such mailings will
               be branded Excite@Home but will alert Program Members that this
               Agreement is to be terminated, the Co-Branded Application will
               continue with e-centives branding, and Program Members will
               continue as a participant in the e-centives service unless they
               explicitly opt out.  The content and copy of such emails shall be
               mutually agreed upon.

          ii)  The first email will be exclusive to e-centives (i.e., it will
               not mention similar services from Excite@Home or other third
               parties) and will alert Program Members of the continuation of
               the e-centives service directly from e-centives. Program Members
               shall be further alerted that their membership in the e-centives
               service shall continue unless they explicitly opt-out.
               Excite@Home shall not promote competing services in such contact
               or otherwise discourage Program Members from continuing to use
               the e-centives service as provided directly by e-centives.

          iii) The second email will not be exclusive to e-centives. It will
               include the same e-centives alerts as in the first email, but may
               offer a replacement Excite@Home service and a notification that
               the Program Member will remain in such an Excite@Home-provided
               service unless they specifically opt-out. Excite@Home shall not
               discourage Program Members from continuing to use the e-centives
               service directly from e-centives, but may offer an additional
               choice. It is conceivable that any one end user customer could
               use both services.

          iv)  Any such communications will be subject to Excite@Home's
               then-current privacy policy.

     b)   In the event that the Agreement is terminated pursuant to Section
          16.a.v. due to e-centives' acquisition by an Excite@Home Named
          Competitor, or by an entity controlling or controlled by an
          Excite@Home Named Competitor, e-centives or its assigns or designates
          may not contact any Users for whom User Data has been provided
          pursuant to this Agreement, excluding those that have opted out in
          accordance with Section 5(a) of Exhibit D. In the event of such
          termination, e-centives will not be eligible for any refund of
          pre-termination payments made to Excite@Home.

               claim at Application Provider's sole cost and expense.

     c)   Except as specified in this Section, neither party makes any warranty
          in connection with the subject matter of this Agreement and hereby
          disclaims any and all implied warranties, including all implied
          warranties of merchantability and fitness for a particular purpose
          regarding such subject matter.

20.  LIMITATION OF LIABILITY

     Except as provided by Sections 19(a)(iii)(2), (a)(iii)(3), (b)(iii)(2) and
     (b)(iii)(3):

     a)   Neither party will have liability for any damages other than direct
          damages. In no event will either party be liable to the other for any
          special, incidental or consequential damages, whether based on breach
          of contract, tort (including negligence) or otherwise, whether or not
          that party has been advised of the possibility of such damage.

     b)   Either party's liability for damages shall be limited to the amounts
          actually paid by the other party.

21.  DISPUTE RESOLUTION

     a)   The parties agree that any breach of either of the parties'
          obligations regarding trademarks, service marks or trade names and/or
          confidentiality would result in irreparable injury for which there is
          no adequate remedy at law. Therefore, in the event of any breach or
          threatened breach of a party's obligations regarding trademarks,
          service marks or trade names or confidentiality, the aggrieved party
          will be entitled to seek equitable relief in addition to its other
          available legal remedies in a court of competent jurisdiction. For the
          purposes of this Section only, the parties consent to venue in either
          the state courts of the county in which Excite@Home has its principal
          place of business or the United States District Court for the Northern
          District of California.

     b)   In the event of disputes between the parties arising from or
          concerning in any manner the subject matter of this Agreement, other
          than disputes arising from or concerning trademarks, service marks or
          trade names and/or confidentiality, the parties will first attempt to
          resolve the dispute(s) through good faith negotiation. In the event
          that the dispute(s) cannot be resolved through good faith negotiation,
          the parties will refer the

        dispute(s) to a mutually acceptable mediator for hearing in the county
        in which Excite@Home has its principal place of business.

     c) In the event that disputes between the parties arising from or
        concerning in any manner the subject matter of this Agreement, other
        than disputes arising from or concerning trademarks, service marks or
        trade names and/or confidentiality, cannot be resolved through good
        faith negotiation and mediation, the parties will refer the dispute(s)
        to the American Arbitration Association for resolution through binding
        arbitration by a single arbitrator pursuant to the American Arbitration
        Association's rules applicable to commercial disputes. The arbitration
        will be held in the county in which Excite@Home has its principal place
        of business.

22.  GENERAL

     a) Governing Law. The Agreement will be governed by and construed in

        actual state or country of residence or incorporation of Application
        Provider.

     b) Assignment. Neither party may assign this Agreement, in whole or in
        part, without the other party's written consent (which will not be

        connection with a merger, reorganization or sale of all, or
        substantially all, of such party's assets or capital stock. Any attempt
        to assign this Agreement other than as permitted above will be null and
        void.

        with express courier, upon confirmation of receipt of facsimile or email
        or five (5) days after deposit in the mail. Notices will be sent to a
        party at its address set forth below or such other address as that party
        may specify in writing pursuant to this Section.

     d) No Agency. The parties are independent contractors and will have no
        power or authority to assume or create any obligation or responsibility
        on behalf of each other. This Agreement will not be construed to create
        or imply any partnership, agency or joint venture.

     e) Audit Rights. A party obligated to make payments and/or provide User
        Data hereunder shall keep for 3 years proper records and books of
        account relating to the computation of such payments and/or the
        compilation and content of such User Data. Once every 12 months, the
        party receiving payment and/or User Data records or its designee may
        inspect such records to verify for accuracy. Any such inspection will be
        conducted in a

     manner that does not unreasonably interfere with the inspected party's
     business activities. In the case of underpayments, the inspected party
     shall immediately make any overdue payments disclosed by the audit plus
     applicable interest. Such inspection shall be at the inspecting party's
     expense; however, if the audit reveals overdue payments in excess of 5% of
     the payments owed to date, the inspected party shall immediately pay the
     cost of such audit, and the inspecting party may conduct another audit
     during the same 12 month period. In the case of inaccurate and/or outdated
     User Data, the providing party shall immediately provide accurate User Data
     and/or updated User Data (to the extent such party has updated User Data.

f)   Force Majeure.  Any delay in or failure of performance by either party
     under this Agreement will not be considered a breach of this Agreement and
     will be excused to the extent caused by any occurrence beyond the
     reasonable control of such party including, but not limited to, acts of
     God, power outages and governmental restrictions.

g)   Severability.  In the event that any of the provisions of this Agreement
     are held by to be unenforceable by a court or arbitrator, the remaining
     portions of the Agreement will remain in full force and effect.

h)   Entire Agreement.  This Agreement is the complete and exclusive agreement
     between the parties with respect to the subject matter or related matters
     hereof, superseding any prior agreements and communications (both written

     Sponsorship Agreement effective on March 5, 1999 that currently is in
     force between the two parties to this Agreement shall remain in force, on
     an interim basis only, and will terminate at the end of the calendar month
     that the Co-Branded Application launches on the Excite@Home Shopping
     service without further compensation from either party.

i)   Waiver.  The failure of either Party to require performance by the other
     Party of any provision of this Agreement will not affect the full right to
     require such performance at any time thereafter; nor will the waiver by
     either Party of a breach of any provision of this Agreement be taken or
     held to be a waiver of the provision itself.

j)   Modification.  This Agreement may only be modified by a written document
     executed by both parties.

k)   Construction.  The section headings appearing in this Agreement are
     inserted only as a matter of convenience and in no way define, limit,

1.   DEFINITIONS

     a)   "Untargeted Offers" are those offers generated from either party's
          network of merchant partners, to be extended to all Users for the
          benefit of attracting shoppers.

     b)   "Targeted Offers" are e-centives offers made available only to Program

2.   TREATMENT OF UNTARGETED OFFERS

     a)   The parties shall establish by mutual agreement prices for the sale
          of Untargeted Offers for display in the Co-Branded Application.

     b)   The parties will share equally all revenue from the sale of
          Untargeted Offers sold for display in the Co-Branded Application.
          This equal division of revenue shall not extend to any placement of
          Untargeted Offers outside the Co-Branded Application. For Untargeted
          Offers that appear both on the Co-Branded Application and elsewhere
          on the Excite Network, revenue attributable to placement on the
          Co-Branded Application shall be calculated based on the price to be
          established as set forth in Section 2.a of this Exhibit, and the
          parties will share equally such revenue.

     c)   The price to be established as set forth in Section 2.a of this
          Exhibit shall not apply to mass listings of paper or local coupons.
          The parties will share equally all revenue from the listing of paper
          or local coupons in the Co-Branded Application.

     d)   Each party shall receive without charge space for twenty (20)
          Untargeted Offers each month. This allocation of free Untargeted

          Agreement.

                                   EXHIBIT B

                     CONTENT DESCRIPTION AND SPECIFICATIONS
                            ("APPLICATION CONTENT")

The following describes the general product plan for the Co-Branded Application:

1.   CUSTOMER OFFERS

     a)   There shall be four distinct types of offers:

          i)   Traditional e-centives offers, which are classified as Targeted
               Offers;

          ii)  Excite@Home-exclusive e-centives offers, which are classified as
               Targeted Offers;

          iii) Other Excite@Home Member exclusive offers, which are classified
               as Untargeted Offers;

               (1)  May be unrelated to e-centives and will have redemption off
                    the e-centives-hosted experience.

          iv)  As deemed appropriate by Excite@Home, other offers that may or
               may not be exclusive to Excite@Home which are provided as a feed
               to e-centives, which are classified as Untargeted Offers;

               (1)  Required so that Members perceive e-centives-hosted content
                    as a superset of Excite@Home's traditional content;

               (2)  Important not to have a binary selection -- non-Excite@Home-
                    Member-exclusive offers in one area and Excite@Home-Member-
                    exclusive offers in another -- an unacceptable user
                    experience.

          v)   Design cues will be used to differentiate the different types of
               offers seen by Members, as shown below:

</TABLE>

                        * Must convert to Excite@Home Member status to redeem

     b)   e-centives will use commercially reasonable efforts to support up to
          a combined 10,000 initial offers from Section 1.a.iii and 1.a.iv of
          this Exhibit B on the Effective Date of this Agreement. Excite@Home
          shall have the right to specify an increased capacity of offer
          presentment at its sole option upon giving three months' advance
          notice to e-centives at any point during the Term of this Agreement,
          presuming such request shall be reasonable.

4.   OFFER PLACEMENT

     To ensure an opportunity for both parties to have a reasonable chance to
     display their own offers within the Co-Branded Application, the following
     prioritization of offers shall be made within any content area served by
     e-centives:

     a)   For the first page presented within any shopping category area,

          i)   All Targeted Offers shall have placement priority above any
               Untargeted Offers.

          ii)  Within the Targeted Offers region, the top 30% of the offer
               placement locations on the first page within a category of the
               Co-Branded Application (not including banner or sponsorship
               placements) will be allocated to Excite@Home exclusive
               e-centives offers. The remaining 70% of such first pages, along
               with subsequent pages within each category, the offer placement
               locations will be split 50%/50% between Excite@Home and
               e-centives and will be served in an alternating order.

          iii) Similarly, within the Untargeted Offers region, the top 30% of
               the offer placement locations on the first page within a
               category of the Co-Branded Application (not including banner or
               sponsorship placements) will be allocated to Excite@Home. The
               remaining 70% of such first pages, along with subsequent pages
               within each category, the offer placement locations will be
               split 50%/50% between Excite@Home and e-centives and will be
               served in an alternating order.

     b)   For the second and any following pages presented within any shopping
          category area, half of the offer placement positions will be
          allocated to Excite@Home and the other half will be allocated to
          e-centives and the position of said placements on the page shall be
          random.

5.   CUSTOMER BRANDING EXPERIENCE

     a)   Until offer selection is made, branding shall be, at Excite@Home's
          option, "Excite" or "Excite@Home" with a tag line "powered by
          e-centives."

     b)   When offer management or redemption occurs, "Excite (or alternately,
          Excite@Home, as detailed in Section 3.a of this Exhibit) powered by
          e-centives" shall be replaced by cobranding, including full logo
          treatment for e-centives. For any branding at the merchant subject to
          final merchant approval, e-centives shall use commercially reasonable
          efforts to ensure that both Excite@Home and e-centives branding
          elements are present.

     c)   Both traditional e-centives offers and Excite@Home e-centives offers
          will contain e-centives branding elements within an application that
          is otherwise Excite@Home branded.

     d)   The Co-Branded Application shall conform to Excite@Home Third-Party
          Application standards, including:

          i)   Page weight;

          ii)  Presence of advertising banners and/or sponsorship placements
               served by Excite@Home/MatchLogic at Excite@Home's exclusive
               option;

          iii) Color, fonts, layout, design standards, header, footer,
               navigational elements, tabbing metaphors, etc.;

          iv)  Navigational elements directing traffic to non-e-centives content
               (e.g., Excite@Home Mail and other Excite@Home Shopping
               destinations);

          v)   Excite@Home's Third-Party Application Standards may change over
               the Term of this Agreement. As they do, e-centives may be
               required to make periodic design enhancements to comply with
               these Standards. Any such required changes shall be reasonable
               and shall be materially similar to changes required of other
               applications and application providers subject to Excite@Home's
               Third-Party Application Standards.

     e)   The Co-Branded Application shall be designed to appear to the customer
          as being Excite@Home; analogs to the goal would be Excite@Home's
          sports content area at http://www.excite.com/sports, as it appears on
          the Effective Date of this Agreement (see Exhibit C), which is served
          by a third-party firm but carries only Excite@Home messaging cues.

     f)   Other Excite@Home Member Offers, and Non-Excite@Home-Member Offers,
          as highlighted in the matrix in Section 1.b of this Exhibit B, may
          also require third-party branding in their presentation.

6.   OFFER HIERARCHY SYNCHRONIZATION

     a)   e-centives does not need to adopt Excite@Home's directory structure
          but must use similar categorization methodology. For example, Autos
          and Electronics may be categories at the same level in the hierarchy,
          but Autos and Cameras would not be at the same level.

     b)   e-centives must map to Excite@Home's Shopping directory hierarchy,
          which may change from time to time during the Term of this Agreement.

     c)   e-centives must adopt Excite@Home's naming conventions (e.g.
          Excite@Home's "Autos" label vs. e-centives' "Automotive" label).

     d)   e-centives must provide product and/or offer search capabilities that
          are comparable to Excite Network offerings, including local (zip
          code) and off-line redemption. Any such required capabilities shall
          be reasonable and shall be materially similar to capabilities
          required of other applications and application providers subject to
          Excite@Home's Third-Party Application Standards.

7.   PLACEMENT

     a)   During the first year of the Agreement a persistent "Above-the-Fold"
          link shall remain present in the Excite@Home Shopping content area,
          or its subsequent replacement, or an equivalent area as determined by
          Excite@Home, that directs end users to the Co-Branded Application,
          the phrasing of which shall be mutually agreed upon. "Above-the-Fold"
          shall mean in a position generally viewable by an end-user customer
          using an Internet browser which has been maximized to full screen on

     b)   Excite@Home shall sell e-centives Thematic or Supplemental emails at

          discounted email rates. If Excite@Home does not sell such emails, or
          all positions within such emails, then e-centives may do so.

          shall assume its own costs in both sending outbound email and in
          providing necessary reporting and data to the other party.

     a)   Excite@Home maintains records concerning whether Excite@Home Users
          have opted in or opted out of receiving contacts from Excite@Home
          ("first-party contacts"). From time to time, Excite@Home Users who

          out of first-party contacts.

     b)   Excite@Home or a designated agent shall provide notice to Application
          Provider when Program Members whose User Data records have been
          licensed to Application Provider opt out of receiving any first-party
          contacts subsequent to licensing. This notice shall be provided on a
          schedule and in a format to be mutually agreed upon.

     c)   Within forty-eight (48) hours of receiving notice that a Program

          shall:

                                   EXHIBIT F

                        PROMOTION ON EXCITE@HOME NETWORK

1.  OFFERS

    a)  The parties will work together to develop mutually agreed upon modules
        designed to promote the Co-Branded Application, which may appear on the
        Excite.com homepage for some Users.

    b)  At its discretion, Excite@Home may include up to five rotating links on
        the My Excite Start Page ("MESP"). At Excite@Home's discretion,
        Excite@Home may include Excite@Home exclusive e-centives offers, non-
        exclusive e-centives offers may also get rotation on MESP, or general
        calls to action to the Co-Branded Application.

    c)  At Excite@Home's discretion, links may be included in the "My Services"
        module. All decisions regarding this module remain Excite@Home's,
        including but not limited to the name and relative placement of the
        module on MESP. This module may not remain as a default module on the
        page over the entire length of the Agreement.

    d)  No e-centives branding of any kind will be present on MESP.

2.  OFFER CATEGORIES

    a)  This Section applies to the publicly accessible narrowband offering from
        Excite@Home, currently available at http://www.excite.com.

    b)  Excite@Home intends to use a randomization function to surface offers on
        MESP in order to provide category specification by user and to support
        dynamic content delivery for each server-refreshed page view. This
        technique will support all e-centives categories and personalized user
        category filtering, but will not support offers that can appear in
        multiple categories or offer weighting.

    c)  Of all e-centives implementation links on MESP, any single category can
        have only one link placement.

    d)  For a category to be surfaced, there must be three unique offers in that
        category. The minimum of three offers per category must remain fresh;
        if more than one week has elapsed without new offers being available
        then a status message indicating no new offers in the category selected
        will appear.

    e)  To prevent multiple appearances of a single offer on one MESP page view,
        every offer must be tagged to only one e-centives category.

3.   USER TYPES

     a)   Anonymous Users and Excite@Home Members with no personalization of the
          My Services module:

          i)   Excite@Home may display two to five links at its sole option. All

               have at most one link.

               preferences.

          iii) Excite@Home Members shall retain unilateral control to turn all
               offer presentments off.

4.   IMPLEMENTATION

     a)   e-centives shall write the necessary application for Excite@Home
          provided API to automate bulk update of available offers into
          Excite@Home's Concorde system. The targeted completion date shall be
          12-16 weeks from the Effective Date of this Agreement.

     b)   The placement of e-centives promotional links on the default front
          page will be implemented in a test mode for a pre-determined period of
          time. Specific success measures, including increases in the conversion
          rate of non-Excite@Home-Members to Excite@Home-Members, must be met
          prior to making the decision to continue default placement.

     c)   Access to the e-centives organizer will be from links within Member
          Services and Shopping and potentially other locations as well, at
          Excite@Home's sole discretion.
