     Agreement shall apply to:  (i) the co-branding and marketing of the
     EarthLink Group's Internet Services; (ii) the marketing of the Sprint 


                                        2


     Group's LD Services; and (iii) the marketing of other
     Telecommunications Services of the Sprint Group as mutually agreed
     upon by the Parties.

     3.   Relationship.

          (a)  Subject to the provisions of this Agreement, the Sprint
     Party and each of the other members of the Sprint Group hereby
     appoints each of the members of the EarthLink Group as its agent to
     sell the Sprint Group's LD Services and other Telecommunications
     Services as agreed to by the Parties (collectively, the "Sprint
     Services"), and the EarthLink Party and each of the other members of
     the EarthLink Group hereby appoints each of the members of the Sprint
     Group as its agent to sell Internet Services.  Each Party accepts its
     respective appointment for itself and on behalf of the members of its
     respective Group.  The Sprint Party will use reasonable efforts to
     cause Sprint PCS to appoint the members of the EarthLink Group as its
     agents to sell PCS  services prior to the Effective Date.  If Sprint
     PCS fails to make such appointment by the Effective Date, Section
     7(f) shall apply.  In the event that Sprint PCS makes such
     appointment, Sprint PCS shall be deemed a member of the Sprint Group
     and included therein for purposes of this Agreement.

          (b)  No member of a Group has the authority to act on behalf of
     the other Party's Group nor may any member of either Party's Group
     bind the members of the other Party's Group except as provided in
     this Agreement.

          (c)  Orders submitted by customers who sign up through the
     Sprint Group for Internet Services are not binding on the EarthLink
     Group until accepted by the EarthLink Group, which shall be evidenced
     by the EarthLink Group's provision of Internet Services to a
     customer.  The EarthLink Group reserves the right to decline any
     order for Internet Services solicited or taken by the Sprint Group,
     provided the EarthLink Group will not discriminate against or apply
     any more stringent standards to a potential Sprint Group generated
     customer than any other potential EarthLink Group customer.

          (d)  Orders submitted by customers who sign up through the
     EarthLink Group for Sprint Services are not binding on the Sprint
     Group until accepted by the Sprint Group, which shall be evidenced by
     the Sprint Group's provision of LD Services and/or Telecommunications
     Services, as applicable, to a customer.  The Sprint Group reserves
     the right to decline to accept any order for Sprint Services
     solicited or taken by the EarthLink Group, provided the Sprint Group
     will not discriminate against or apply any more stringent standards
     to a potential EarthLink Group generated customer than any other
     potential Sprint Group customer.

          (e)  The EarthLink Group will provide customer service for
     Internet Services for Sprint Group generated customers in accordance
     with its general practices and procedures.  Customers for Internet
     Services will be customers of the EarthLink Group for Internet
     Services and will remain customers of the EarthLink Group for the
     Internet Services after termination of this Agreement unless such
     customers elect to terminate their relationship with the EarthLink
     Group.


                                        3


          (f)  The Sprint Group will provide customer service for Sprint
     Services and those customer service functions relating to Internet
     Services as the Sprint Group deems appropriate for Internet Services
     for its EarthLink Group generated customers in accordance with its
     general practices and procedures.  Customers for Sprint Services will
     be customers of the Sprint Group for Sprint Services but not for
     Internet Services and will remain customers of the Sprint Group for
     Sprint Services after termination of this Agreement unless such
     customers elect to terminate their relationship with the Sprint
     Group.

          (g)  Nothing in this Agreement shall limit the Sprint Group's
     ability to package or bundle various Sprint Services with the
     EarthLink Group's Internet Services or its flexibility regarding
     pricing of the Sprint Services within such package or bundle, in each
     case as the Sprint Group deems appropriate.

          (h)  The terms set forth on Schedule B shall apply to any
     customer of the EarthLink Group who is generated through the Sprint
     Group's business service channels.

          (i)  Without the Sprint Party's prior written consent, no member
     of the EarthLink Group will enter into any agreement that would
     contractually prevent or contractually restrict the Sprint Group from
     marketing and selling the Core Internet Application Set through any
     Sprint marketing channel; provided, however, the EarthLink Group may
     enter into such agreements after consultation with the Sprint Party
     without violating this Section 3(i) if the Sprint Party receives a
     credit against the number of subscribers required by Schedule H
     hereof equal to twenty percent (20%) of the number of subscribers
     obtained by the EarthLink Group through such agreements for the
     applicable annual period.

     4.   Joint Marketing Committee.

          (a)  Each Party will appoint up to three representatives to
     serve as members of a six person "Joint Marketing Committee".  Each
     member shall serve at the pleasure of their respective Party. The
     Joint Marketing Committee will work together in a proactive and
     cooperative spirit in seeking, defining and implementing marketing
     opportunities consistent with the Plan (see Section 4(d)) and to
     identify methods and opportunities to increase Internet Service and
     Sprint Service revenues. 

          (b)  The Joint Marketing Committee will be responsible for
     making recommendations regarding modifications to the terms of this
     Agreement in the event that competitive or other circumstances
     dictate; however, neither Party will be obligated to amend or modify
     this Agreement based on such recommendation.

          (c)  The Joint Marketing Committee will meet as often as
     necessary, either in person or by telephone, but no less than on a
     monthly basis for the first six (6) months after the Effective Date
     and no less than once per three (3) month period after such initial
     six (6) months. Either Party may call a Joint Marketing Committee
     meeting upon seven (7) days' notice.  


                                        4


          (d)  The Joint Marketing Committee will prepare and produce a
     sales and marketing plan for the Internet Services for each year of
     the Agreement (the "Plan").  The Plan shall be published no later
     than November 30 of each calendar year for the following calendar
     year.  During the first calendar year in which this Agreement becomes
     effective, the Plan shall be published as soon as commercially
     reasonable following the Effective Date.  The Plan will address and
     establish in reasonable detail the plan of execution for the joint
     marketing activities of the Internet Services, and the Sprint Group
     and the EarthLink Group shall devote resources and efforts reasonably
     necessary to insure the Plan's goals and targets are met, the cost
     and expenses of which to be born as determined in the Plan. 

          The Joint Marketing Committee will similarly prepare and produce
     a plan to address the sale and marketing of Sprint Services by the
     EarthLink Group.

          (f)  Any action by the Joint Marketing Committee will require
     the majority approval of all of its members.

     5.   Branding.

          (a)  The Sprint Group and the EarthLink Group, in accordance
     with Sections 25 and 26 and the "Branding Strategy" set forth in
     Schedule L, shall include the agreed upon co-brand in:

               (i)  all of the Sprint Group's marketing, advertising and
          other similar material relating to or referencing any of the
          EarthLink Group's Internet Services; and

               (ii) all of the EarthLink Group's marketing, advertising
          and other similar material (e.g., software jackets, packaging,
          web page(s), etc.) used to promote and offer for sale or
          otherwise relating to the Internet Services and/or the Sprint
          Services in the Territory.  

     The Parties intend to have the Internet Service as a co-branded
     service which appears to the general public as part of the Sprint
     Group portfolio of product and service offerings.

     
          (b)  No member of the EarthLink Group shall be under any
     obligation to reference the Sprint Brand or the co-brand when
     referring generally to the members of the EarthLink Group in their
     corporate capacities.  No member of the EarthLink Group will be
     required to reference any member of  the EarthLink Group, or the
     EarthLink Group as a whole, as a Sprint Group-controlled entity.

          (c)  The Sprint Group and the EarthLink Group will each comply
     with the terms of the Branding Strategy set forth in Schedule L.

     6.   Quality of Service.  The EarthLink Group will provide a quality
of service and attendant customer and technical support for the Core
Internet Application Set (and any other 

                                        5


Internet Services provided by the EarthLink Group that are marketed under
the EarthLink-Sprint co-brand but excluding the Sprint Group provided
Internet Network Services which are a part of the Internet Services) that
is of high quality.  In the event that the EarthLink Group fails to meet
this quality standard, it shall use substantial, diligent and continuous
efforts to seek to achieve or restore such service quality.  If the
EarthLink Group fails to meet such standard for a continuous 120 day
period or for three periods of 45 or more days each during a calendar year
following written notice from the Sprint Party to the EarthLink Party, the
Sprint Party may terminate this Agreement, provided that the Sprint Group
is not then in material breach of this Agreement; provided, however, that
the determination of whether the EarthLink Group has met this quality
standard will be determined through the dispute resolution process
described in Section 21, such dispute resolution process to commence 60
days following written notice from the Sprint Party to the EarthLink Party
of the EarthLink Group's failure to meet the quality standard if the
Sprint Party determines that the EarthLink Group has not cured such
failure within such 60-day period.  If the failure to meet such quality
standard is attributable to a failure or defect in any services or
products provided by a third party (e.g., the dial-up Internet access
services), the Sprint Party will have the right to terminate this
Agreement as provided above, but the EarthLink Group will not be deemed in
breach of this Agreement for failure to meet such quality standard.

     7.   Exclusivity.

          (a)  The provisions of this Section 7 apply only to activities
     within the Territory and apply to each of the EarthLink Group and the
     Sprint Group.

          (b)  The Sprint Group will not promote, advertise, market,
     co-brand, package, bundle, develop, offer or sell, or enter into any
     express or tacit agreement to permit its names to be used in
     connection with, a set of Internet-related products and services
     (whether as a series of individual products and services or as an
     integrated grouping or package of products and services) that is the
     same as or substantially similar to the Core Internet Application Set
     (as in effect from time-to-time), other than those of the EarthLink
     Group.  The Sprint Group will not bid on, acquire or directly or
     indirectly, own, manage, operate, join, control or finance, or
     participate in the management, operation, control or financing of any
     provider of any set of Internet-related products and services
     (whether as a series of individual products and services or as an
     integrated grouping or package of products and services) that is the
     same as or substantially similar to the Core Internet Application Set
     (as in effect from time-to-time), other than the EarthLink Group. 
     Nothing in this Section shall prohibit or restrict the Sprint Group
     from (i) owning less than 5% of a company which engages in a
     Restricted Services Business (as defined in Section 24), or
     (ii) engaging in any activity relating to products or services that
     perform the same function as any individual elements and/or
     components of the Core Internet Application Set so long as the set of
     such products and services (whether packaged or marketed as a series
     of individual products and services or as an integrated grouping or
     package of products and services) are not the same as or
     substantially similar to the Core Internet Application Set; provided,
     however, that if the Sprint Group intends to obtain any such elements
     or components from a third party the EarthLink Group shall have the
     first right of refusal to provide the Sprint Group with such elements
     and 


                                        6


     components of the Core Internet Application Set if such elements and
     components supplied by the EarthLink Group are of substantially
     similar quality as those available from third parties and are
     provided by the EarthLink Group at the same price and on
     substantially similar terms to the Sprint Group as the lower of the
     price and terms upon which those elements and components are offered
     by the EarthLink Group to third parties or the price and terms
     otherwise generally commercially available to the Sprint Group for
     such elements and components.

          (c)  The EarthLink Group will not promote, advertise, market,
     co-brand, package, bundle, develop, offer, or sell any LD Service or
     Telecommunications Services or services that are the same as or
     substantially similar to the LD Services or Telecommunications
     Services other than those of the Sprint Group.  The EarthLink Group
     will not bid on, acquire or directly or indirectly, own, manage,
     operate, join, control or finance, or participate in the management,
     operation, control or financing of, or act as an agent or
     representative for, or enter into any express or tacit agreement to
     permit its name to be used in connection with, or permit its Internet
     Services to be marketed, sold or distributed by, any Material
     Provider of LD Services or Telecommunications Services other than the
     Sprint Group and, after Sprint PCS has appointed each member of the
     EarthLink Group as its agents pursuant to Section 3(a), Sprint PCS. 
     Nothing in this Section shall prohibit or restrict the EarthLink
     Group from owning less than 5% of a company which sells LD Services
     or Telecommunications Services.  A business or entity will be deemed
     to be a "Material Provider" of LD Services or Telecommunications
     Services if such business or entity (together with its Affiliates)
     derives from the sale of LD Services and Telecommunications Services
     (i) more than 5% of its gross revenues in any fiscal year, or
     (ii) more than $25,000,000 of gross revenues in any fiscal year.

          (d)  Notwithstanding anything in Section 7(c) above or any other
     provision of this Agreement, the EarthLink Group may continue to
     offer a co-branded Core Internet Application Set which is marketed
     and/or sold by the telecommunications companies listed in Schedule E,
     consistent with the terms of its current agreements with these
     companies.  The EarthLink Group will not extend or renew such
     agreements beyond January 1, 1999 unless either:

               (i)  The EarthLink Group delivers the Core Internet
          Application Set on a private label basis (with no EarthLink
          Group Brand); or

               (ii) The Sprint Party gives prior written approval, which
          approval shall not be unreasonably withheld.

          (e)  Notwithstanding Section 7(c) above, until such time as the
     Sprint Group has developed an Internet Telephony service to offer to
     consumers, the EarthLink Group may offer such service of any third
     party of its choice.  However, any Internet Telephony obtained by the
     EarthLink Group from a third party may not be co-branded with the
     third party brand and may not be offered under the EarthLink-Sprint
     co-brand; provided, however, that notwithstanding the generality of
     the foregoing, the EarthLink Group may 


                                        7


     offer as a component of its Core Internet Application Set an
     Internet Telephony application that can be run with the Core
     Internet Application Set in substantially similar fashion (and would
     be presented to the customer with a substantially similar branding
     approach) as the VocalTec application that is currently made
     available by the EarthLink Group to its customers.  At such time as
     the Sprint Group has developed such service, the EarthLink Group
     will be required to obtain such service from the Sprint Group unless
     the EarthLink Group is able to obtain a service with materially
     superior performance  or a comparable service on superior terms from
     a third party; provided, however, that (i) the EarthLink Group will
     have the right to continue to obtain the Internet Telephony solution
     it then currently distributes until it can terminate the relevant
     agreement without liability and without material adverse effect on
     its business and its reputation; (ii) the Sprint Group will have the
     right to match any third party offer to provide Internet Telephony
     to the EarthLink Group on the same terms including terms addressing
     both quality and economics; and, (iii) the EarthLink-Sprint co-brand
     may be used only to market the Core Internet Application Set of
     which such Internet Telephony services may be a component and will
     not in any way be used to market or promote the Internet Telephony
     services on a stand-alone basis.

          (f)  If Sprint PCS has not appointed the members of the
     EarthLink Group as its agents to sell wireless services prior to the
     Effective Date, neither Section 7(c) nor any other provision of this
     Agreement will restrict the EarthLink Group from entering into
     arrangements with one or more cellular and/or PCS service providers
     pursuant to which the EarthLink Group may sell such cellular and/or
     PCS services.  At the option of the EarthLink Group, such cellular
     and/or PCS service may be marketed and sold under the third-party
     provider's brand.  If such appointment by Sprint PCS occurs after
     the Effective Date, the EarthLink Group will thereafter be bound by
     Section 7(c) with respect to all cellular and PCS services, subject
     to its rights under those agreements entered into by the EarthLink
     Group prior to such date, which the EarthLink Group will terminate
     as soon as contractually permissible; provided, however, that
     EarthLink may continue its third-party cellular and PCS agreements
     for such time as the EarthLink Group, in its reasonable discretion,
     determines is necessary to avoid material adverse effects on its
     business and on its reputation as a result of the termination of its
     business relationship with such third parties.

          (g)  Notwithstanding Section 7(b) above or any other provision
     of this Agreement, the Sprint Group will be permitted to appoint one
     or more Internet service providers ("ISPs") other than the members
     of the EarthLink Group as its agents for the sale of its branded LD
     Services and Telecommunications Services so long as the Sprint Group
     does not bill the Internet related services provided by such ISP on
     an integrated basis with the Sprint Services.

          (h)  Neither Section 7(b) nor any other provision of this
     Agreement will restrict the Sprint Group in any way with respect to
     the "Corporate Dial" service that it currently offers or any similar
     product or service that is designed primarily for large corporate
     accounts and offers enhanced features that are not then included in
     the Core 

                                       8


     Internet Application Set; provided that the Sprint Group shall not
     offer or sell any services or products in connection with such
     "Corporate Dial" service which are the same as or substantially
     similar to the Core Internet Application Set (unless the Core
     Internet Application Set is provided by the EarthLink Group) so long
     as the Core Internet Application Set provided by the EarthLink Group
     is of substantially similar quality  and is provided at the same
     price and on substantially similar terms as such services are
     generally commercially available to the Sprint Group.

          (i)  Notwithstanding Section 7(c) above or any other provision
     of this Agreement, but subject to the restrictions in Section 11,
     the EarthLink Group may market, package, offer or sell ATM and frame
     relay telecommunications services of any third party but only for
     the sole purpose of providing access to the public Internet;
     provided, however, the EarthLink Group may display the mark of or
     otherwise identify the name of the vendor of such services solely
     for the purpose of identifying the source of such services.

     8.   The Sprint Group's Responsibilities.

          (a)  Subject to contractual restrictions, the Sprint Group
     shall devote reasonable resources and efforts to ensure that the
     EarthLink Group has access to the Sprint Group's consumer
     (i) third-party controlled and managed distribution channels;
     (ii) OEM channels; and (iii) marketing properties, including Radio
     Shack and other telecommunications services and product resellers
     (collectively referred to as "Third-Party Channels").  The EarthLink
     Group shall involve the Sprint Party in all communications with
     Third Party Channels.  Nothing in this Section shall require the
     Sprint Group to take any action which would adversely impact the
     Sprint Group's relationship with Third-Party Channels.  The Sprint
     Group's current Third-Party Channels are listed on Schedule F.

          (b)  The Sprint Group will, within the Sprint Party's
     reasonable discretion, permit the EarthLink Group to participate in
     the Sprint Group's promotional activities and communicate with the
     Sprint Group's consumer customers regarding  the Core Internet
     Application Set, including, without limitation, providing the
     EarthLink Group, where permitted by law, with adequate information
     necessary to identify such customers.  The EarthLink Party will, at
     the Sprint Party's election, pay either (i) the One Time Payment
     described on Schedule H for each customer generated through such
     channel, or (ii) incremental marketing costs associated with such
     channel activities; however, under no circumstances will EarthLink
     pay both such amounts.

          (c)  Subject to contractual restrictions, the EarthLink Group
     will cooperate with the Sprint Group in maintaining the Sprint
     Group's preferred position on the Netscape and Microsoft referral
     servers; provided, however, that the Sprint Group's presence on
     those servers will, from the Effective Date, be the co-branded Core
     Internet Application Set.


                                       9


          (d)  The Sprint Group shall devote reasonable resources and
     efforts in opening its consumer channels to actively promote, market
     and sell the Core Internet Application Set and shall exert
     reasonable efforts to ensure that those channels actively promote,
     market and sell the Core Internet Application Set.  The EarthLink
     Party will, at the Sprint Party's election, pay either (i) the One
     Time Payment described on Schedule H for each customer generated
     through such channel, or (ii) incremental marketing costs associated
     with such channel activities; however, under no circumstances will
     the EarthLink Party pay both such amounts.

          (e)  The Sprint Group shall purchase those items and pay to the
     EarthLink Party those amounts as described on Schedule G.

     9.   The EarthLink Group's Responsibilities.

          (a)  The Sprint Party shall be compensated for any Sprint Group
     generated customer of the Core Internet Application Set, as set
     forth in Schedule H. If the Core Internet Application Set is
     materially changed from the current set, or as new Internet Services
     are introduced by the EarthLink Group, the Parties will negotiate
     commercially reasonable terms for the Sprint Group to sell these
     services, which in no event shall be less favorable than the terms
     offered by the EarthLink Group to others for selling the same or
     similar services which terms will be comparable to those generally
     available in the market place.  Costs associated with the generation
     of customers for Internet Service, under this Section 9(a), shall be
     borne by the Sprint Group.

          (b)  The EarthLink Party shall be responsible for payment to
     Netscape and Microsoft of referral fees incurred as a result of, and
     costs associated with,  the Core Internet Application Set's presence
     on those parties' referral servers.

          (c)  The EarthLink Party shall be responsible for payment of
     all bounties, royalties, and residuals to Third-Party Channels due
     to sales of its  Internet Services, provided that the EarthLink
     Party agrees to such terms prior to the channel participant selling
     the Internet Services, unless the Sprint Group elects to pay such
     third party payments in exchange for the commission payment set
     forth in Schedule H.

          (d)  The EarthLink Group will, at its cost and using reasonable
     efforts, actively market, promote and sell Sprint Services. 
     Compensation to the EarthLink Group for its sale of the LD Services
     will equal a percentage of total Net Collectible Call Usage Revenue
     as described on Schedule G.  For the purpose of this Agreement, Net
     Collectible Call Usage Revenue is defined as monthly revenue
     (excluding taxes, bad debt, fraud and subsequently credited
     charges).  Compensation to the EarthLink Group for its sale of the
     Telecommunications Services shall be mutually agreed upon subject to
     Schedule G.

          (e)  The EarthLink Party will, at the Sprint Group's cost and
     within the EarthLink Party's reasonable discretion, permit the
     Sprint Group to participate in the EarthLink Group's various
     promotional activities and communicate with the EarthLink Group's
     consumer customers regarding LD Services and Telecommunications
     Services, 

                                       10


     including, without limitation, providing the Sprint Group, where
     permitted by law and contract, with adequate information necessary
     to identify such customers.

          (f)  The EarthLink Group will, in all cases, be responsible for
     any costs related to the production of the EarthLink Group software,
     CD ROM or similar media and related packaging.

          (g)  The EarthLink Group will make available to all Sprint
     Group customers any promotional offering generally available to the
     EarthLink Group's non-Sprint customers of the Core Internet
     Application Set at the same prices and on the same terms.

          (h)  If the Core Internet Application Set is of substantially
     similar quality to other similar service packages that could be
     utilized by the Sprint Group, then the Sprint Group will obtain, and
     the EarthLink Group will provide, the Core Internet Application Set
     to the Sprint Group for any new Internet Network Service the Sprint
     Group develops on prices and terms at least as favorable to the
     Sprint Group as the EarthLink Group offers the Core Internet
     Application Set to any other third party and under prices and terms
     no less favorable to the Sprint Group than are generally
     commercially available to the Sprint Group for a substantially
     similar set of services.  If the Sprint Group develops an Internet
     Network Service and makes it available to third parties, the Sprint
     Group will make such service available to the EarthLink Group on the
     best terms as it makes the service available to third parties.

     10.  Training.  Each Party's Group shall provide, at its own costs,
qualified personnel to train a mutually agreed upon number of
representatives of the other Party's Group with respect to the training
Parties' Group's services and products necessary to enable each Party's
Group to optimally perform its obligations under this Agreement.

     11.  The EarthLink Group's Telecommunications Services Requirements;
          The Sprint Group's Core Internet Application Set Requirements.

          (a)  Subject to the limitations contained in this Agreement,
     the Sprint Group will provide, and the EarthLink Party agrees to
     acquire, the EarthLink Group's Telecommunications Services
     requirements (exclusive of: (i) dial-up Internet access services
     including the attendant high-speed circuits necessary to deliver the
     Internet Services, and (ii) other high-speed access services
     including ATM and frame relay when used to provide a dedicated
     connection to the Internet) from the Sprint Group, provided the
     Sprint Group offers such services to the EarthLink Group at the best
     prices available to the EarthLink Group from a third party for
     substantially similar services.  The Sprint Group acknowledges that
     the EarthLink Group has existing voice and data services agreements
     with third parties.  The Sprint Group may elect to pay any penalties
     and other fees related to contractually permissible early
     termination of such agreements or may permit the EarthLink Group to
     continue to purchase such services under such agreements for the
     entire term of such agreements.  Notwithstanding the generality of
     the foregoing, the Sprint Group shall not require the EarthLink
     Group to effect an early termination of 

                                       11

     
     any such agreement if such termination would cause a material
     disruption to the EarthLink Group's business or constitute a breach
     of any such agreement.

          (b)  The obligation of the EarthLink Group to provide the
     Sprint Group with certain opportunities to provide dial-up Internet
     access services to the EarthLink Group are set forth in Section 1.6
     of the Network Services Agreement among the Parties of even date
     herewith, which Section is incorporated herein by this reference and
     shall survive for the term of this Agreement.  Furthermore, for the
     term of this Agreement the EarthLink Group will purchase from the
     Sprint Group high-speed access services, including ATM and frame
     relay, for the purpose of providing dedicated connections to the
     Internet, provided such services are offered by the Sprint Group at
     the best prices and on substantially similar terms as are available
     to the EarthLink Group from a third party for substantially similar
     services.

          (c)  The EarthLink Group will provide, and the Sprint Group
     agrees to acquire, the Sprint Group's Core Internet Application Set
     requirements for the Sprint Group's internal needs for services
     substantially similar to the Core Internet Application Set from the
     EarthLink Group, provided the EarthLink Group offers such services
     to the Sprint Group at the best prices and on substantially similar
     terms as are available to the Sprint Group from a third party for
     substantially similar services.

     12.  E-Mail.  The e-mail domain for the Internet Service shall be
"earthlink.net", except as customers may request unique or vanity domain
names.

     13.  Product Enhancements.

          (a)  The EarthLink Party and the Sprint Party agree to
     negotiate a billing and collection agreement for integrated billing
     services for the Sprint Group's LD and Telecommunications Services
     and the EarthLink Group's Internet Services, which results in the
     EarthLink Group achieving substantially the same economic results of
     its now existing merchant agreements (e.g., credit card agreements)
     for its customer billings.  If, after one (1) year from the date the
     integrated billing services are implemented, the Sprint Group's
     incremental costs of providing integrated billing services differs
     materially from the EarthLink Group's payment for the services, the
     Sprint Party and the EarthLink Party agree they will renegotiate the
     terms of the billing and collection agreement.  Any renegotiated
     increases or decreases in the EarthLink Group's payments to the
     Sprint Group for integrated billing services shall not exceed
     twenty-five percent (25%).

          (b)  (i)  If the Sprint Group seeks the enhancement of existing
          Internet Services or the development of new Internet Services
          not currently offered by the EarthLink Group, the Sprint Party
          will present a request for such enhancement or development to
          the EarthLink Party.  The Parties agree to negotiate in good
          faith the developmental targets, milestones, acceptance testing
          schedules and delivery dates for any such enhancements or
          developments (the "Development Schedule"). The EarthLink Group
          shall, if the EarthLink Party elects, develop at its cost the
          new service or enhancement and negotiate commercially
          reasonable terms with 

                                       12


          the Sprint Party for the Sprint Group to sell the service as a
          sales agent of the EarthLink Group.  If the EarthLink Group
          declines to develop the new service or enhancement, the Sprint
          Party can require the EarthLink Group to develop such service
          or enhancement at the Sprint Party's cost, unless such
          development effort would have a material adverse impact on the
          EarthLink Group's operations or product development efforts, as
          reasonably determined by the EarthLink Party.

               (ii) If the EarthLink Party declines for the EarthLink
          Group to enhance existing Internet Services or develop new
          Internet Services on the aforestated grounds, or if within
          forty-five (45) following the EarthLink Party's receipt of the
          Sprint Party's request the Parties have not agreed to the
          Development Schedule, the Sprint Group may at its own cost
          develop (either directly or by outsourcing) the enhancement or
          service.  After commercially reasonable acceptance testing, the
          EarthLink Group will (if requested by the Sprint Party)
          implement the development.  If such development is funded by
          the Sprint Party (whether developed by the EarthLink Group, the
          Sprint Group or a third party), the Sprint Group will own such
          development and will license the development to the EarthLink
          Group on commercially reasonable terms. 

     Notwithstanding anything in this Section 13(b) to the contrary, if
     the development or commercialization of any enhancement(s) of
     existing Internet Services or the development of new Internet
     Services would have a material adverse effect on the EarthLink Group
     or its product development efforts, the EarthLink Group shall not be
     required to develop or implement such new Internet Services or
     enhancements to Internet Services.  To the extent such items are
     developed by the Sprint Group, directly or through a third party,
     the Sprint Group will work with the EarthLink Group, at the Sprint
     Party's expense (however, the EarthLink Group shall be responsible
     for its own personnel costs), to ensure the proper integration of
     such enhancements and new Internet services into the Internet
     Services and the Parties' business relationship.

     14.  Lawful Performance and Related Covenants.  Each Party's Group
must lawfully perform its obligations under this Agreement.  Neither
Party's Group will commit any act that would reasonably be expected to
reflect unfavorably on the other.  Neither Party's Group will
misrepresent products and services or the prices of products and
services.  Neither Party's Group will sponsor or participate in any
illegal pyramid or multilevel marketing system. 

     15.  Invoicing; Payment; Interest and Payment Default.

          (a)  Each Party will deliver to the other on a monthly basis an
     invoice reflecting the aggregate amounts payable by the other
     Party's Group to the invoicing Party for the month most recently
     completed as computed in accordance with this Agreement.  Each such
     invoice will reflect, in detail, the computation and a detailed
     description of the invoiced amounts.

          (b)  Each Party shall pay to the other all invoiced amounts
     within thirty (30) days of receipt of an invoice; provided, however,
     that to the extent any amount of an 



                                       13


     invoice is subject to a bona fide, good faith dispute, the payment
     of such disputed amount shall be determined in accordance with
     dispute resolution processes provided for under Section 22.  Any
     undisputed amounts will be paid to and promptly credited by the
     payee Party.  In the case of a disputed amount, if after sixty (60)
     days such dispute has not been resolved, the payor Party shall place
     one hundred percent (100%) of the disputed amount in an escrow
     account established for the payee Party's benefit until such dispute
     is resolved.  Upon resolution of the dispute, the Parties shall be
     paid the disputed amounts held in escrow and any interest having
     accrued on the disputed amounts held in the escrow account in
     proportion to the amount to be received by each Party with respect
     to the resolution of the dispute.  To the extent the amount held in
     escrow is insufficient to fully pay the payee Party as established
     by the resolution of the dispute, the payor Party shall, within
     fifteen (15) days of the resolution of the dispute, pay such balance
     to payee party.  The Parties shall bear the costs of the escrow
     account in inverse proportion to the amounts distributed to the
     Parties from the escrow account.

          (c)  After the expiration of the thirty (30) day payment
     period, all undisputed unpaid invoiced amounts shall bear interest
     at the rate of one percent (1%) per month, accruing daily, until
     paid.  In the event that the payor Party fails to pay any undisputed
     amount when due and upon receipt of written notice from payee party
     of nonpayment, the payor Party shall be deemed in default of this
     Agreement if the undisputed amount is not then paid within the later
     to occur of thirty (30) days from the date of the payor Party's
     receipt of such notice of nonpayment or ninety (90) days from the
     date of the applicable invoice (a "Payment Default").

     16.  Confidentiality.

          (a)  Definition.  "Proprietary Information" means any
     information or material regarding the terms of this Agreement or
     which:  (i) is confidential and proprietary to the disclosing
     Party's Group, which derives economic value from not being generally
     known and is the subject of reasonable efforts by the disclosing
     party to maintain its secrecy; or (ii) the disclosing Party's Group
     obtains from any third party, which the disclosing party treats as
     confidential and proprietary, whether or not owned by the disclosing
     Party's Group.

          (b)  Restriction.  All Proprietary Information disclosed by one
     Party's Group to the other Party is deemed to be confidential,
     restricted and proprietary to the disclosing Party's Group.

          (c)  Use.  The Parties agree to use the Proprietary Information
     received from the other Party's Group only to accomplish the intent
     of this Agreement or as otherwise set forth in this Agreement.  No
     other rights to trade Brand, inventions, copyrights, patents, or any
     other intellectual property rights are implied or granted under this
     Agreement or by the conveying of Proprietary Information between the
     Parties and their Groups.  


                                       14


          (d)  Copying.  Proprietary Information supplied is not to be
     reproduced in any form except in performing a Party's obligations
     under this Agreement.

          (e)  Care.  The receiving Party must provide the same degree of
     care to avoid disclosure and unauthorized use of the Proprietary
     Information as it provides to protect its own similar proprietary
     information.  All Proprietary Information must be retained by the
     receiving Party in a secure place with access limited to only such
     of the receiving Party's employees, attorneys, accountants or agents
     who need to know such information to perform a Party's obligations
     under this Agreement and to such third Parties as the disclosing
     Party has consented to by prior written approval.  A receiving Party
     may disclose the disclosing Party's Group's Proprietary Information
     to members of the receiving Party's Group provided that the
     receiving Party, together with the member of the receiving Party's
     Group which may violate this Section 16, will be jointly and
     severally liable for any breach of this Section 16 that is caused by
     any member of such Party's Group.

          (f)  Ownership.  All Proprietary Information, unless otherwise
     specified in writing, (i) remains the property of the disclosing
     Party or its Group, as the case may be, and (ii) such Proprietary
     Information, including all copies of such information, must be
     returned to the disclosing Party or its Group, as the case may be,
     or destroyed after the receiving Party's need for it has expired or
     upon request of the disclosing Party, and, in any event, upon
     termination of this Agreement.

          (g)  Limitation.  The Parties agree that the term "Proprietary
     Information" does not include information which:

               (i)  has been or may in the future be published or is now
          or may in the future be otherwise in the public domain through
          no fault of the receiving Party or its Group;

               (ii) prior to disclosure pursuant to this Agreement is
          property within the legitimate possession of the receiving
          Party or its Group;

               (iii)     subsequent to disclosure pursuant to this
          Agreement is lawfully received from a third party having rights
          in the information without restriction of the third party's
          right to disseminate the information and without notice of any
          restriction against its further disclosure;

               (iv) is independently developed by the receiving Party's
          Group; or  

               (v)  is obligated to be produced under order of a court of
          competent jurisdiction or other similar requirements of a
          governmental agency, so long as the Party or the Party's Group
          required to disclose the information provides the other Party
          with prior notice of such order or requirement and limits to
          the extent possible.


                                       15


          (h)  Relief.  The Parties agree that a breach of this
     Section 16 may give rise to irreparable injury to the non-breaching
     Party and its Group that cannot be compensated for adequately by
     damages.  Consequently, the Parties agree that each Party and the
     members of its Group shall be entitled, in addition to all other
     remedies available, to injunctive and other equitable relief to
     prevent a breach of this Section 16 of this Agreement and to secure
     the enforcement of the provisions of this Section 16 in any court of
     competent jurisdiction in the United States or any state thereof
     (and the Parties agree to waive any requirement for the posting of
     bond in connection with such remedy).

          (i)  Term.  Neither Party nor such Party's Group may disclose
     the Proprietary Information of the other Party for a period which is
     the longer of (i) four (4) years from the date of disclosure or
     (ii) two (2) years following the date of termination of this
     Agreement.  A Party and/or its Group may never disclose trade
     secrets of the other Party and/or its Group so long as such
     Proprietary Information continues to qualify as a trade secret under
     applicable law.

          (j)  Further Protection.  If a Party determines that it or its
     Group is required by law to disclose this Agreement or its terms or
     any other Confidential Information (including any press release or
     filing with the Securities and Exchange Commission or any other
     government agency), such Party shall provide a copy of such proposed
     disclosure to the other Party for its review and comment prior to
     such disclosure and shall, together with the other members of this
     Group, cooperate in full with the other Party and its Group with
     respect to any protective orders, requests for confidentiality or
     similar protections that are reasonably requested to be sought by
     the other Party to protect the confidentiality of such information.

     17.  Liability of Parties.  EXCEPT AS SPECIFICALLY PROVIDED FOR IN
THIS AGREEMENT, IN NO EVENT WILL EITHER PARTY OR THEIR GROUPS BE LIABLE
FOR SPECIAL, INDIRECT, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, OR
LOSS OF PROFITS, ARISING FROM THE RELATIONSHIP OR THE CONDUCT OF BUSINESS
UNDER THIS AGREEMENT.

     18.  [Reserved].

     19.  Indemnification.

          (a)  Each Party (the "Indemnifying Party") agrees to indemnify
     and hold harmless the other Party and the other members of its Group
     and its and their permitted assigns, and its partners, officers,
     directors, employees and agents, and each of their representatives,
     and its successors and assigns (collectively, the "Indemnitees") at
     all times from and after the Effective Date against and in respect
     of any Damages (hereinafter defined) suffered by the Indemnitees as
     a result of (i) any breach by the Indemnifying Party and its Group
     of any representation, warranty or covenant contained in this
     Agreement or (ii) any claims, actions or demands (collectively,
     "Claim") by a third party to the extent caused by or arising out of
     (A) any negligent  act or omission on the part of the Indemnifying
     Party, (B) any act or omission by the Indemnifying Party and its 

                                       16



     Group that does not conform to the requirements of the Agreement or
     (C) the Indemnitee's use of the Indemnifying Party's brand in
     accordance with the terms of this  Agreement.

          (b)  For the purposes of this Agreement and unless otherwise
     specifically provided, the term "Damages" shall include (i) all
     amounts finally awarded or charged against an Indemnitee, (ii) any
     amounts paid in settlement as permitted by this Section 19 and
     (iii) all out-of-pocket expenses or costs incurred by such
     Indemnitee(s), including reasonable professional and attorneys' fees
     and expenses.

          (c)  Promptly upon receipt by the Indemnitee of notice of any
     demand, assertion, claim, action or proceeding, judicial or
     otherwise, with respect to any matter as to which an Indemnifying
     Party has agreed to indemnify an Indemnitee under the provisions of
     this Agreement, the Indemnitee will give prompt notice thereof in
     writing to the Indemnifying Party, together with a statement of such
     information respecting a Claim, as the Indemnitee shall then have.
     The Indemnifying Party shall have the right to contest and defend
     the Claim, with respect to which it has been called upon to
     indemnify the Indemnitee under the provisions of this Agreement;
     provided, however, that:

               (i)  notice of intention so to contest shall be delivered
          to the Indemnitee within twenty (20) calendar days from the
          receipt by the Indemnifying Party of notice of the Claim;

               (ii) the Indemnifying Party will pay all costs and
          expenses of such contest or defense, including all reasonable
          attorneys' and accountants' fees, and the cost of any bond
          required by law to be posted in connection with such contest or
          defense;

               (iii) such contest or defense shall be conducted by
          attorneys employed by the Indemnifying Party, at the
          Indemnifying Party's sole cost and expense, but the Indemnitee
          shall have the right to participate in such proceedings and to
          be represented by attorneys of its own choosing, at the
          Indemnitee's cost and expense without contribution or
          indemnification by the Indemnifying Party for such costs or
          expenses;

               (iv) if after such opportunity, the Indemnitee does not
          elect to participate in the defense in any such proceedings,
          the Indemnitee (subject to paragraph (vi) below) shall be bound
          by the results obtained by the Indemnifying Party, including
          without limitation any out-of-court settlement or compromise;

               (v)  if the Indemnifying Party assumes the defense, the
          Indemnitee(s) will not settle, or attempt to settle, such claim
          without the Indemnifying Party's consent which consent may be
          withheld in the Indemnifying Party's good faith discretion; and

                                       17


               (vi) the Indemnifying Party will not settle any claim
          without the prior written consent of the Indemnitees which
          consent may be withheld in the Indemnifying Party's good faith
          discretion, unless the settlement contains a complete and
          unconditional release of the Indemnitee(s), and the settlement
          does not involve the imposition of any nonmonetary relief on
          the Indemnitees.

     20.  Publicity.  Except for legally mandated disclosures, any press
releases or public announcements relating to this Agreement or the terms
of the Agreement must be mutually agreed upon by the Parties.  Any
legally mandated disclosures shall be subject to the provisions of
Section 16(j).  Notwithstanding the foregoing, neither Party nor any
member of its Group will be required to obtain approval of the other
Party or any member of its Group with respect to incidental references to
the co-branded Internet Services or the other Party's Brand included in
general corporate announcements and press releases.

     21.  Dispute Resolution.  Prior to instituting any action pursuant
to Section 29(f), the Parties will attempt to resolve any dispute between
the Parties' Groups either with respect to the interpretation of any
provision of this Agreement or with respect to the performance by either
Party's Group under this Agreement as specified in this Section.

          (a)  Upon written request of either Party, a dispute shall be
     submitted for resolution to a dispute resolution team which shall be
     comprised of two representatives from each Party (the "Integrated
     Action Team").

          (b)  The Integrated Action Team shall meet as often as
     necessary to gather and furnish to each Party all information with
     respect to the matter in issue, which is appropriate and germane for
     its resolution.

          (c)  The Integrated Action Team shall discuss the dispute and
     negotiate in good faith in an effort to resolve the dispute without
     the necessity of any formal proceeding relating thereto.

          (d)  During the course of such negotiation, all reasonable
     requests made by one Party to the other for nonprivileged
     information reasonably related to this Agreement and the dispute
     will be honored in order that each Party may be fully advised of the
     other Party's position.

          (e)  The specific format for such discussions will be left to
     the discretion of the Integrated Action Team, but may include the
     preparation of agreed upon statements of fact or written statements
     of position furnished by each Party to the other Party.

          (f)  If the Integrated Action Team fails to resolve the dispute
     within thirty (30) days after the  initial delivery of a request by
     either Party to submit the dispute to the Integrated Action Team
     (the "Notice"), then the dispute shall be escalated to an officer of
     Sprint and an officer of EarthLink, for their review and resolution
     within forty-five (45) days after  delivery of the Notice.

                                       18


          (g)  If the officers referred to above fail to resolve the
     dispute within forty-five (45) days after the Notice, then the
     dispute shall be escalated to the President of Sprint and the
     President of EarthLink for their review and resolution within sixty
     (60) days after the Notice.

          (h)  If the dispute is not resolved by the Parties' Presidents
     within sixty (60) days after the Notice, then the Parties may
     initiate formal proceedings.

          (i)  Notwithstanding anything in this Section to contrary, the
     Integrated Action Team may stay the time periods set forth in this
     Section upon a unanimous vote of its members to do so.

          (j)  Notwithstanding anything in this Agreement to the
     contrary, either Party may resort to court action for injunctive
     relief at any time if the dispute resolution process set forth in
     this Section would permit or cause irreparable damage to such Party
     or any third Party claiming against such Party, due to delay arising
     out of the dispute resolution process.

     22.  Continued Performance.  The Parties agree that their Groups
shall continue performing their respective obligations under this
Agreement while disputes are being resolved unless and until such
obligations are terminated or expire in accordance with the provisions of
the Agreement.

     23.  Audit.  Each Party's Group will maintain complete and accurate
accounting records during the term of this Agreement and for two (2)
years after the termination of this Agreement in a consistent form to
substantiate the direct monetary payments and reporting obligations of
one Party to the other Party under this Agreement.  Each Party may, upon
reasonable advance written notice to the other Party, conduct during the
other Party's regular business hours, and in accordance with applicable
law and reasonable security requirements, audits of the other Party's
Group of such direct monetary payment and reporting obligation accounts
and records, in accordance with the following guidelines and
restrictions:

          (a)  the audit may be conducted by members of the internal
     audit department who are employees of the auditing Party;

          (b)  the audited Party and its Group may require the auditing
     Party's employee to conduct the audit on the premises of the audited
     Party's Group;

          (c)  the audited Party's Group will have the right to have an
     employee or representative present at all times during the audit;

          (d)  the auditing Party will not have direct unrestricted
     access to the audited Party's Group's computer database without the
     consent of the audited Party, and will be entitled to review only
     those specific records of the audited Party's Group directly related
     to the monetary obligations of the audited Party's Group under this
     Agreement, specifically limited to customer activations,
     deactivations, customer billing records, 

                                       19



     records related to media/advertising expenditures, market launch
     expenditures, market development funds/escrow arrangements, and any
     other records directly related to the monetary obligations of such
     Party's Group hereunder; and

          (e)  the auditing Party's audit of activation, deactivation,
     and customer billing records will be limited to a reasonable random
     sampling audit of those records.

Subject to the restrictions set forth above, the audited Party and the
members of its Group will cooperate fully with the auditing Party.  All
reasonable fees and costs incurred (including a reasonable charge for the
services of any employee of the audited Party directly involved in the
audit) by either Party in connection with such audits will be paid by the
auditing Party.  The Party whose group is audited will have the right to
have the results of any such audit reviewed by their internal auditing
staff or by the audited Party's independent accountants who then audit
the financial statements of the audited Party ("Independent Auditors"). 
The cost of such internal or Independent Auditors review shall be borne
by the audited Party.  The audited Party and its Group shall use its
commercially reasonable efforts to immediately correct any deficiencies
related to performance proved to exist by such audit.

     Each Party may seek an audit of the other Party and its Group,
pursuant to this Section, no more than once every twelve (12) months. 
These audit rights shall survive until the period ending twelve (12)
months following the termination of all residual payments under the
applicable Schedule.

     Termination.

          (a)  Notwithstanding Section 1 of this Agreement, the Sprint
     Party may, if not then in material breach of this Agreement,
     terminate this Agreement with sixty (60) days prior notice in the
     event the EarthLink Group is in material breach of any
     representation, warranty, obligation or agreement set forth in this
     Agreement and such breach is not substantially cured within sixty
     (60) days of notice of such breach.  If the breach requires more
     than sixty (60) days to cure, such sixty (60) day period will be
     extended for an additional sixty (60) days if the EarthLink Group is
     exercising substantial, diligent and continuous efforts to cure such
     breach; provided, however, that if the EarthLink Group is not
     exercising substantial, diligent and continuous efforts to cure such
     breach, the Sprint Party may terminate this Agreement immediately
     pursuant to notice given at any time after the sixty (60) day cure
     period (as may be extended pursuant to this Section 24(a)) but prior
     to the cure of such breach.

          (b)  The Sprint Party shall have the option to terminate this
     Agreement immediately by written notice to the EarthLink Party upon
     the occurrence of:

               (i)  a Business Combination as defined in the Governance
          Agreement between the Parties of even date herewith; or

               (ii) consummation of a tender or exchange offer, merger,
          consolidation, share exchange or other business combination, in
          which the Sprint 

                                       20


     or Sprint L.P. is a party, or a sale of securities,
     recapitalization, liquidation, dissolution or similar transaction
     involving Sprint or Sprint L.P., or any acquisition of, in any
     manner, directly or indirectly, a material equity interest in, or a
     material amount of voting equity securities of Sprint or Sprint L.P.
     (with the acquisition of beneficial ownership of fifty percent (50%)
     or more of voting equity securities being deemed material for this
     purpose) or assets of Sprint or Sprint L.P. (a "Sprint Change in
     Control Transaction") if the entity that, as a result of such
     transaction, owns 50% or more of the equity securities or assets of
     Sprint or Sprint L.P. or owns the Sprint Brand or is otherwise the
     surviving entity of such transaction (the "Survivor"), is engaged,
     directly or indirectly, either itself or through Affiliates, in a
     Restricted Services Business (defined below).

          (c)  Notwithstanding Section 1 of this Agreement, the EarthLink
     Party may, if not then in material breach of this Agreement,
     terminate this Agreement with sixty (60) days prior notice in the
     event the Sprint Group is in material breach of any representation,
     warranty, obligation or agreement set forth in this Agreement and
     such breach is not substantially cured within sixty (60) days of
     notice of such breach.  If the breach requires more than sixty
     (60) days to cure, such sixty (60) day period will be extended for
     an additional sixty (60) days if the Sprint Group is exercising
     substantial, diligent and continuous efforts to cure such breach;
     provided, however, that if the Sprint Group is not exercising
     substantial, diligent and continuous efforts to cure such breach, 
     the EarthLink Party may terminate this Agreement immediately
     pursuant to notice given at any time after the sixty (60) day cure
     period (as may be extended pursuant to this Section 24(c)) but prior
     to the cure of such breach.

          (d)  The EarthLink Party may, if not then in material breach of
     this Agreement, terminate this Agreement immediately by written
     notice to the Sprint Party in the event of:

               (i)  an acquisition by any member of the Sprint Group,
          directly or indirectly, either in whole or in part, either via
          a tender or exchange offer, merger, consolidation, share
          exchange or other business combination or an asset purchase or
          any other business transaction, of a third party which provides
          a set of services and products (whether as a series of
          individual products and services or as an integrated grouping
          or package of products and services) which are the same as or
          substantially similar to the Core Internet Application Set
          (such portion of the business of such third party as consists
          of the provision of such services being referred to as a
          "Restricted Services Business"), if the Sprint Group has not
          within 180 days after the consummation of such acquisition
          effected the (x) transfer of the Restricted Services Business
          to the EarthLink Group on terms and conditions mutually
          acceptable to the Parties (which opportunity the EarthLink
          Party agrees to review in good faith); (y) termination of the
          Restricted Services Business; or (z) divestiture of the
          Restricted Services Business; or

                                       21


               (ii) a Sprint Change in Control Transaction if the
          Survivor is engaged in a Restricted Services Business and has
          not within 180 days after the consummation of the Sprint Change
          in Control Transaction effected the (x) transfer of the
          Restricted Services Business to the EarthLink Group on terms
          and conditions mutually acceptable to the Parties (which
          opportunity the EarthLink Party agrees to review in good
          faith); (y) termination of the Restricted Services Business; or
          (z) divestiture of the Restricted Services Business; or

               (iii) the termination of the Governance Agreement under
          clause (ii) (when Sprint's Percentage Interest is less than the
          Lower Threshold, as such terms are defined in the Governance
          Agreement), (iv) and (vi) of Section 7.01(a) thereof.

     The EarthLink Party will not unreasonably withhold its consent to an
     extension of such 180 day period referred to in Sections 24(d)(i)
     and (ii) for an additional period not to exceed 180 days if the
     Sprint Group is not permitting the Restricted Services Business to
     use the Sprint Brand or the Sprint Group's marketing and
     distribution channels and is diligently and in good faith seeking to
     consummate such divestiture as soon as possible.  In the event of an
     event described in clauses (i) and (ii) of Section 24(d) above: 
     (a) during the 180 day period provided for in such clauses (and any
     extension thereof agreed to by the EarthLink Party and any time
     period thereafter prior to the EarthLink Party's election (or waiver
     of its right) to terminate this Agreement), the exclusivity
     restrictions contained in Section 7(b) shall not apply and no breach
     of such provision shall be deemed to have occurred by reason of the
     conduct of a Restricted Services Business involved in such a
     transaction during such time period; and (b) if the EarthLink Party
     does not exercise its option to terminate this Agreement within 90
     days following such prior 180 day period (as same may be extended
     pursuant to this paragraph), the Sprint Group shall be permanently
     released from the exclusivity restrictions under Section 7(b) for
     the Restricted Services Business (including any internal growth or
     expansion of such Business but excluding any acquisition of another
     Restricted Services Business).

          (e)  Either Party may terminate this Agreement immediately by
     written notice to the other Party upon the termination of the
     Governance Agreement under clause (i) of Section 7.01 thereof.

          (f)  (i)  Upon termination of this Agreement by the EarthLink
          Party pursuant to Sections 24(d)(i) or 24(d)(ii) or by the
          Sprint Party pursuant to Section 24(b)(ii), the Sprint Group
          shall pay to the EarthLink Party a termination fee (the
          "Termination Fee") to reimburse the EarthLink Group for its
          loss of benefits under this Agreement, which payment is not in
          lieu of any damages which may at the time of termination have
          previously inured to the EarthLink Group as a result of any
          breach of this Agreement by the Sprint Group prior to the
          termination date, subject to clause (iv) below.  The actual
          losses resulting to the EarthLink Group from the termination of
          this Agreement pursuant to Sections 24(d)(i), 24(d)(ii) or 

                                       22


          24(b)(ii) would be difficult to determine, and the Parties
          agree that the Termination Fee is a fair and reasonable
          estimate of such losses in the form of liquidated damages and
          is not a penalty.

               (ii) The Termination Fee shall consist of two components,
          the sum of which shall be paid as a single fee.  The first
          component of the Termination Fee (the "First Component") shall
          equal $60 million on the Effective Date and shall decrease pro
          rata per day over the five (5) year period commencing on the
          Effective Date; provided that if the termination of this
          Agreement occurs pursuant to Sections 24(d)(i), 24(d)(ii) or
          24(b)(ii) prior to the second anniversary of the Effective
          Date, the First Component shall equal $60 million.  The First
          Component shall be paid, at the EarthLink Party's election, in
          cash or in shares of the Preferred Stock of Newco then-owned by
          the Sprint Group that were issued pursuant to the Investment
          Agreement, each such share having a value for such purpose
          equal to the value of the Newco common stock into which such
          share of Preferred Stock is convertible as of the date of such
          termination assuming use of the Conversion Ratio as defined in
          the Governance Agreement; provided that the EarthLink Party
          cannot require the Sprint Party to surrender shares of
          Preferred Stock if such surrender would violate federal or
          state securities laws. 


               (iii) The second component of the Termination Fee will
          equal the sum of the fees which would have been payable under
          "Subscriber Commitment" on Schedule H for the period from such
          termination through the end of the five (5) year commitment
          period in such provision assuming that no additional
          subscribers would have been generated under such provision
          after the effective date of the termination of this Agreement.
          
               (iv) The Termination Fee represents the sole amount that
          will be payable from each Party to the other upon termination
          of this Agreement other than damages accrued prior to the date
          of termination resulting from any prior breach (excluding for
          these purposes any damages relating to the period after the
          termination of this Agreement) and amounts owing under any
          express provision of this Agreement that have accrued prior to
          the date of termination.

          (g)  Except as provided in this Section 24, termination of this
     Agreement is without prejudice to any other rights or remedies of
     the Parties.  Termination of this Agreement for any cause does not
     release either Party nor the members of its Group from any liability
     which, at the time of termination, has already accrued to the other
     Party and its Group subject to Section 24(f)(iv).


          (h)  Upon the termination of this Agreement the Parties and
     their Groups will use commercially reasonable efforts to mitigate
     the non-liquidated damages caused by the occurrence of such event.


                                       23


          (i)  The occurrence of any of the events that trigger a right
     to termination pursuant to Sections 24(b), 24(d) or 24(e) shall not
     constitute a breach of this Agreement, including, without
     limitation, Section 7(b).

     25.  Sprint Brand License.

          (a)  License.  The Sprint Party grants to the EarthLink Party a
     non-exclusive, royalty free, nontransferable license, to use the
     Sprint Brand in the Territory (directly or through a sublicense to
     the members of the EarthLink Group and the EarthLink Group's
     distributors, resellers and channel partners) and during the term of
     this Agreement for the purpose of marketing, promoting and selling
     the Sprint Services, the Core Internet Application Set, Internet
     Telephony services (to the extent permitted under Section 7(e)) and
     such other Internet Services as are agreed upon in writing by the
     Parties, in each case as specified in this Agreement.  The EarthLink
     Party shall cause the members of the EarthLink Group, and the
     EarthLink Group's distributors, resellers and channel partners to
     properly display and use Sprint's Brand in accordance with this
     Agreement.

          (b)  Control of Brand.

               (i)  The Sprint Party has the right, at all reasonable
          times, to inspect the EarthLink Group's relevant facilities and
          review the manner in which the EarthLink Group uses the Sprint
          Brands so that the Sprint Party may satisfy itself that the
          Sprint Brands are used in accordance with this Agreement;
          provided, however, that Sprint cannot exercise such right in a
          manner which unreasonably interferes with the EarthLink Group's
          normal business operations.

               (ii) The EarthLink Group shall adhere to the trademark
          usage guidelines furnished by the Sprint Party for the
          depiction of the Sprint Brand ("Trademark Usage Guidelines")
          and any reasonable modifications or amendments thereto.  The
          attached Schedule I will function as the current version of the
          Trademark Usage Guidelines.  The EarthLink Group shall adhere
          to the Sprint Party's Marketing Communications Guidelines and
          any reasonable modifications or amendments thereto, the current
          version of which is attached as Schedule J.  In the event of a
          conflict between this Agreement on the one part and either of
          the Trademark Usage Guidelines or Marketing Communications
          Guidelines on the other part, this Agreement shall govern.

               (iii)The EarthLink Group shall include on all advertising
          and promotional materials, packaging and labels bearing the
          Sprint Brand the following notice:

          "[Sprint Mark] is a registered trademark of Sprint
          Communications Company L.P.  Used under license."


                                       24


          With respect to electronic presentations of the Sprint Brand,
          this notice may be contained on EarthLink's web-site under
          "Legal Information" or, if software, in the "About" box or
          where the EarthLink Group's own proprietary notices appear. 

               (iv) Prior to any first use of the Sprint Brand on
          advertising or promotional materials by the EarthLink Group,
          the EarthLink Party agrees to furnish the Sprint Party with
          samples of such advertising and promotional materials,
          packaging and labels bearing any of the Sprint Brand for
          trademark usage approval (which approval shall not be
          unreasonably withheld) to:

          The EarthLink Group shall amend the future use of the Sprint
          Brand in any such advertising and promotional materials,
          packaging and labels if the use of the Sprint Brand is not
          approved by the Sprint Party.  The Sprint Party will have 7
          business days from the date of receipt to approve or object to
          materials submitted for trademark usage approval.  If no
          objection is received by the EarthLink Group within such 7
          business days, such materials will be deemed approved.  Use of
          the Brand by the EarthLink Group that is substantially
          identical to uses of the Brand that have previously been
          approved or that is being used for the same program (with
          substantially similar presentation of the Sprint Brand) as has
          previously been approved do not require submission for
          approval.

               (v)  The EarthLink Group must immediately cease placing
          into its distribution channel any previously approved material
          from which the Sprint Party withdraws its approval.  The Sprint
          Party will not unreasonably rescind approval of any materials
          previously approved.

          (c)  Rights in Brand.

               (i)  The EarthLink Group acquires and will acquire no
          rights, title or interest in the Sprint Brand or the goodwill
          associated with them, other than the right to use the Sprint
          Brand in accordance with this Agreement.  In accepting this
          Agreement, the EarthLink Group acknowledges the Sprint Party's
          ownership of the Sprint Brand, its validity and the goodwill
          connected with it.  The EarthLink Group will not attack the
          Sprint Brand, nor assist anyone in attacking it.  The EarthLink
          Party further agrees that the EarthLink Group shall not make
          any application to register the Sprint Brand, nor to use any
          confusingly similar trademark, service mark, trade name, or
          derivation, during the term of this Agreement or thereafter. 
          This paragraph will survive the termination of this Agreement.


                                       25


               (ii) At the request and sole expense of the Sprint Party,
          the EarthLink Party will execute and will cause any relevant
          member of the EarthLink Group to execute, any papers or
          documents reasonably necessary to protect the rights of Sprint
          in the Sprint Brand and execute and deliver such other
          documents as may be reasonably requested by the Sprint Party.


               (iii)     Sprint represents and warrants that as of the
          date hereof the Sprint Brand does not infringe upon any
          trademarks and is not involved in any opposition, invalidation,
          cancellation or litigation that would threaten the EarthLink
          Group's use of the Sprint Brand in connection with the Core
          Internet Application Set and, to the Sprint Party's knowledge,
          no such action is threatened with respect to the Sprint Brand. 
          In the event that such action occurs, the Sprint Party will
          vigorously protect the Sprint Brand.

          (d)  Infringement.  The EarthLink Party shall promptly notify
     the Sprint Party of any unauthorized use of the Sprint Brand that
     comes to the EarthLink Group's attention.  The Sprint Party in its
     reasonable discretion may take such action as may be required to
     prosecute the infringement.  In the event that the Sprint Party
     decides that action should be taken against such third Parties, the
     Sprint Party may take such action either in its own name, or
     alternatively, the Sprint Party may authorize the EarthLink Party to
     initiate such action in the EarthLink Party's name but the EarthLink
     Party shall have no obligation to do so.  In either event, the
     EarthLink Party agrees and agrees to cause the relevant members of
     the EarthLink Group to cooperate fully with the Sprint Party, at the
     Sprint Party's expense, to whatever extent it is necessary to
     prosecute such action, all expenses being borne by the Sprint Party
     and all damages which may be recovered being solely for the account
     of the Sprint Party.

          (e)  Termination.  In the event the EarthLink Group violates
     the Sprint Brand Trademark Usage Guidelines or the Sprint Marketing
     Communications Guidelines and continues to do so for a continuous 45
     day period or for three periods of 30 days each during a calendar
     year following written notice from the Sprint Party, such violation
     shall constitute a material breach of this Agreement and the Sprint
     Party may terminate this Agreement.

          (f)  Relief.  The Parties agree that a breach of this
     Section 25 may give rise to irreparable injury to the non-breaching
     Party and its Group that cannot be compensated for adequately by
     damages.  Consequently, the Parties agree that each Party shall be
     entitled, in addition to all other remedies available, to injunctive
     and other equitable relief to prevent a breach of this Section 25
     and to secure the enforcement of the provisions of this Section 25
     in any court of competent jurisdiction in the United States or any
     state thereof (and the Parties agree to waive any requirement for
     the posting of bond in connection with such remedy).

                                       26


     26.  EarthLink Brand License.

          (a)  License.  The EarthLink Party grants to the Sprint Party a
     non-exclusive, royalty free, nontransferable license, to use the
     EarthLink Brand and the EarthLink marks described on Schedule C (the
     "Marks") in the Territory (directly or through a sublicense to the
     members of the Sprint Group and the Sprint Group's distributors,
     resellers and channel partners) and during the term of this
     Agreement for the purpose of marketing, promoting and selling
     Internet Services sourced from the EarthLink Group (separately or in
     a package or bundle with LD Services and/or Telecommunications
     Services), in each case as specified in this Agreement.  Sprint will
     cause the members of the Sprint Group and the Sprint Group's
     distributors, resellers and channel partners to properly display and
     use the EarthLink Brand and Marks in accordance with this Agreement. 
     

          (b)  Control of Brand and Marks.

               (i)  The EarthLink Party has the right, at all reasonable
          times, to inspect the Sprint Group's relevant facilities and
          review the manner in which the Sprint Group uses the EarthLink
          Brands and Marks so that the EarthLink Party may satisfy itself
          that the EarthLink Brands and Marks are used in accordance with
          this Agreement; provided, however, that the EarthLink Party
          cannot exercise such right in a manner which unreasonably
          interferes with the Sprint Group's normal business operations.

               (ii) The Sprint Group shall adhere to the trademark usage
          guidelines furnished by the EarthLink Party for the depiction
          of the EarthLink Brand and Marks ("EarthLink Trademark Usage
          Guidelines").  The attached Schedule K will function as the
          current version of the EarthLink Trademark Usage Guidelines.

               (iii) The Sprint Party shall include on all advertising
          and promotional materials bearing the EarthLink Brand or Marks
          the following notice:

          [EarthLink Mark] is a Registered Trademark of  EarthLink
          Network, Inc.  Used under license.

               (iv) Prior to any first use of any of the EarthLink Brand
          and/or Marks by the Sprint Group, the Sprint Party must furnish
          EarthLink with samples of all advertising and promotional
          materials, packaging and labels bearing any of the EarthLink
          Brand for trademark usage approval to:

                    Contracts Manager
                    EarthLink Network, Inc.
                    3100 New York Drive
                    Pasadena, California  91107

          The Sprint Group shall amend the future use of the EarthLink
          Brand and Marks if the use of the EarthLink Brand or Marks is
          not approved by the EarthLink Party.  

                                       27



          The EarthLink Party will have 7 business days from the date of
          receipt to approve or object to materials submitted for
          trademark usage approval.  If no objection is received by
          Sprint within 7 business days, such materials will be deemed
          approved.  Use of the Brand and Marks by the Sprint Group that
          is substantially identical to uses of the Brand and Marks that
          have previously been approved or that is being used for the
          same program (with substantially similar presentation of the
          EarthLink Brand and Marks) as has previously been approved do
          not require submission for approval.

               (v)  The Sprint Group must immediately cease placing
          materials into its distribution channels any previously
          approved material from which the EarthLink Party withdraws its
          approval.  The EarthLink Party will not unreasonably rescind
          approval of any materials previously approved.

          (c)  Rights in Brand.

               (i)  The Sprint Group acquires and will acquire no rights,
          title or interest in the EarthLink Brand and Marks or the
          goodwill associated with them, other than the right to use the
          EarthLink Brand in accordance with this Agreement.  In
          accepting this Agreement, the Sprint Group acknowledges the
          EarthLink Group's ownership of the EarthLink Brand and Marks,
          their validity and the goodwill connected with them.  The
          Sprint Group will not attack the EarthLink Brand or Marks, nor
          assist anyone in attacking them.  Sprint further agrees that
          neither the Sprint Party nor any member of the Sprint Group
          will make any application to register the EarthLink Brand, nor
          to use any confusingly similar trademark, service mark, trade
          name, or derivation, during the term of this Agreement or
          thereafter.  This paragraph will survive the termination of
          this Agreement.

               (ii) At the request of the EarthLink Party, the Sprint
          Party will execute and will cause any relevant member of the
          Sprint Group to execute any papers or documents reasonably
          necessary to protect the rights of the EarthLink Group in the
          EarthLink Brand and Marks and execute and deliver such other
          documents as may be reasonably requested by the EarthLink
          Party.

               (iii)     The EarthLink Party represents and warrants that
          as of the date hereof the EarthLink Brand and Marks do not
          infringe upon any trademarks and are not involved in any
          opposition, invalidation, cancellation or litigation that would
          threaten Sprint's use of the EarthLink Brand and Marks, and to
          the EarthLink Party's knowledge, no such action is threatened
          with respect to the EarthLink Brand or Marks.  In the event
          that such action occurs, the EarthLink Party will vigorously
          protect the EarthLink Brand.

          (d)  Infringement.  The Sprint Party shall promptly notify the
     EarthLink Party of any unauthorized use of the EarthLink Brand or
     Marks that comes to the Sprint Group's attention.  The EarthLink
     Party in its reasonable discretion may take such action 

                                      28
                                       




     as may be required to prosecute the infringement.  In the event that
     the EarthLink Party decides that action should be taken against such
     third parties, the EarthLink Party may take such action either in
     its own name, or alternatively, the EarthLink Party may authorize
     the Sprint Party to initiate such action in the EarthLink Party's
     name but Sprint shall have no obligation to do so.  In either event,
     the Sprint Party agrees to and agrees to cause the Sprint Group to
     cooperate fully with the EarthLink Group to whatever extent it is
     necessary to prosecute such action, all expenses being borne by the
     EarthLink Party and all damages which may be recovered being solely
     for the account of the EarthLink Party.

          (e)  Termination.  In the event the Sprint Group violates the
     EarthLink Trademark Usage Guidelines and continues to do so for a
     continuous 45 day period or for three periods of 30 days each during
     a calendar year following written notice from the EarthLink Party,
     such violation shall constitute a material breach of this Agreement
     and the EarthLink Party may terminate this Agreement.

          (f)  Relief.  The Parties agree that a breach of this
     Section 26 may give rise to irreparable injury to the non-breaching
     Party and its Group that cannot be compensated for adequately by
     damages.  Consequently, the Parties agree that each Party and any
     relevant members of their Groups shall be entitled, in addition to
     all other remedies available, to injunctive and other equitable
     relief to prevent a breach of this Section 26 to secure the
     enforcement of the provisions of this Section 26 in any court of
     competent jurisdiction in the United States or any state thereof
     (and the Parties agree to waive any requirement for the posting of
     bond in connection with such remedy).

     27.  Covenant of Cooperation and Good Faith.  The Parties covenant
to timely and diligently cooperate to effect the goals, objectives and
purposes of this Agreement and to facilitate the performance of their
respective duties and obligations under this Agreement in a commercially
reasonable manner.  Further, the Parties agree to deal and negotiate with
each other in good faith in the execution and implementation of their
duties and obligations under this Agreement.

     28.  Services Not Specifically Covered.  There may be functions,
responsibilities, activities and tasks not specifically described in this
Agreement or the Schedules hereto which are required for the performance
and provision of the Parties' obligations and are an inherent part of, or
a necessary element included within, the Parties' obligations. If such
functions, responsibilities, activities and tasks are mutually determined
by the parties to be required for the proper performance the other
obligations or are an inherent part, or a necessary part, thereof, such
functions, responsibilities, activities and tasks shall be deemed to be
implied by and included within the scope of this Agreement and the
obligations established hereunder to the same extent and in the same
manner as if specifically described in this Agreement and the Schedules
hereto; provided that this Section 28 shall not be interpreted to impose
any material obligations or liabilities on any Party that are not
expressly set forth in this Agreement.

     The Parties shall promptly notify each other of any change in their
     respective addresses or facsimile numbers or of the person or office
     to receive notices, requests or other communications under this
     Section 29(a).  Notice shall be deemed to have been given as of the
     date when so personally delivered, when delivered if sent by United
     States mail, the next day when delivered during business hours to
     such overnight delivery service properly addressed or when receipt
     of a telecopy is confirmed, as the case may be, unless the sending
     Party has actual knowledge that such notice was not received by the
     intended recipient.

          (b)  Entire Agreement.  This Agreement (including the Schedules
     and Schedules) embodies the entire agreement and understanding of
     the Parties in respect to the matter contemplated hereby and
     supersedes and renders null and void all other prior 

                                       30



     agreements and understandings, written and oral, with respect to the
     subject matter hereof, provided that this provision shall not
     abrogate any other written agreement between the Parties executed
     simultaneously with this Agreement.  

          (c)  Waiver.  Except as otherwise permitted in this Agreement,
     the terms or conditions of this Agreement may not be waived unless
     set forth in a writing signed by the Party entitled to the benefits
     thereof.  No waiver of any of the provisions of this Agreement shall
     be deemed or shall constitute a waiver of such provision at any time
     in the future or a waiver of any other provision hereof.  The rights
     and remedies of the Parties are cumulative and not alternative. 
     Except as otherwise permitted in this Agreement, neither the failure
     nor any delay by any Party in exercising any right, power or
     privilege under this Agreement will operate as a waiver of such
     right, power or privilege, and no single or partial exercise of any
     such right, power or privilege will preclude any other or further
     exercise of such right, power or privilege or the exercise of any
     other right, power or privilege.

          (d)  Successors and Assigns.  Except as provided in this
     Agreement, neither this Agreement nor any of the rights, interests
     or obligations under this Agreement shall be assigned or
     transferred, in whole or in part, by any of the Parties or members
     of their Groups without the prior written consent of the other
     Party; provided, however, that such assignment or transfer may be
     made by (i) by the Sprint Party to any of its Affiliates, or
      pursuant to any merger or sale of substantially all of the assets
     of Sprint or such Affiliates (or any transaction having such effect)
     or (ii) by EarthLink to Newco in connection with a merger, exchange
     offer, consolidation, share exchange or other business combination
     with or a sale of assets to Newco or with or to a direct or indirect
     wholly-owned subsidiary of Newco.  Subject to the preceding
     sentence, this Agreement will be binding upon, inure to the benefit
     of, and be enforceable by, the Parties and their respective
     successors and assigns.  Any attempted assignment in violation of
     this Section 29(d) shall be void. 

          (e)  Governing Law.  This Agreement shall be governed by the
     laws of the State of Delaware, without regard to conflict of laws
     principles.

          (f)  Exclusive Jurisdiction and Consent to Service of Process. 
     Subject to Sections 25(f) and 26(f) the Parties agree that any
     action arising out of or relating to this Agreement shall be
     instituted in a Delaware state court or in a federal court sitting
     in such state which shall be the exclusive venue of any such action. 
     Each Party waives any objection which is based on jurisdiction with
     respect to such action, and irrevocably consents and submits to the
     jurisdiction of any such court (and the appropriate appellate
     courts) in any such action.  Any and all service of process and any
     other notice in any such action shall be effective against such
     Party when transmitted in accordance with Section 29(a).  Nothing
     contained herein shall be deemed to affect the right of any Party to
     serve process in any manner permitted by law.  At the time of a
     dispute, the parties may mutually agree that any action arising out
     of or relating to this Agreement may be 

                                       31


     decided through an arbitration proceeding, the details of such
     arbitration proceeding to be mutually agreed upon by the parties at
     the time of the dispute.

          (g)  Waiver of Jury Trial.  THE EARTHLINK PARTY AND THE SPRINT
     PARTY HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL ACTION INVOLVING,
     DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT,
     CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR
     CONNECTED WITH THIS AGREEMENT OR THE RELATIONSHIP ESTABLISHED
     THEREUNDER.

          (h)  Severability.  If any provision of this Agreement as
     applied to any Party or to any circumstance shall be held invalid,
     illegal or unenforceable by any court of competent jurisdiction,
     (i) the validity, legality and enforceability of the remaining
     provisions of this Agreement will remain in full force and effect
     and (ii) the application of such provision to any other part or to
     any other circumstance shall not be affected or impaired thereby. 
     To the extent permitted by applicable law, each Party waives any
     provision of applicable law that renders any provision hereof
     prohibited or unenforceable in any respect.  If any provision of
     this Agreement is held to be unenforceable for any reason, it shall
     be adjusted rather than voided, if possible, in order to achieve the
     intent of the Parties to the extent possible.

          (i)  Counterparts.  This Agreement may be executed in one or
     more counterparts each of which when so executed and delivered shall
     for all purposes be deemed to be an original but all of which, when
     taken together, shall constitute one and the same Agreement.

          (j)  Headings.  The headings used in this Agreement are
     inserted for convenience only and shall not be deemed to constitute
     part of this Agreement or to affect the construction or
     interpretation hereof.

          (k)  No Third-Party Beneficiaries.  Nothing in this Agreement,
     express or implied, shall create or confer upon any person
     (including but not limited to any employees), other than the Parties
     or their respective successors and permitted assigns, any legal or
     equitable rights, remedies, obligations, liabilities or claims under
     or with respect to this Agreement, except as expressly provided
     herein.

          (l)  Interpretation.

          advised by experienced counsel and, to the extent it deemed
          necessary, other advisors in connection with this Agreement. 
          Accordingly, each Party hereby acknowledges that no Party has
          relied or will rely in respect of this Agreement or the

               (ii) No provision of this Agreement shall be interpreted
          in favor of, or against, either of the Parties by reason of the
          extent to which either such Party or its counsel participated
          in the drafting thereof or by reason of the extent to which any
          such provision is inconsistent with any prior draft hereof or
          thereof.

          (m)  Amendment.  No amendment, modification or alteration of
     the terms or provisions of this Agreement, including any Schedules
     hereto or thereto, shall be binding unless the same shall be in
     writing and duly executed by the Party against whom such amendment,
     modification or alteration is sought to be enforced.

          (n)  Guarantee.  By its execution of this Agreement, Newco
     agrees that it will be jointly and severally liable with EarthLink
     for all of the obligations and liabilities of EarthLink, the
     EarthLink Party and the EarthLink Group hereunder, and Newco hereby
     guarantees the full performance by such entities of their respective
     obligations hereunder, including its payment obligations.

          (o)  Survival.  Notwithstanding the expiration or early
     termination of this Agreement for any reason whatsoever, the
     following Sections of this Agreement shall survive any such
     expiration or termination:  Sections 16, 17, 19, 20, 21, 23 and 29. 
     In addition, the termination of this Agreement shall not relieve any
     Party from any payment obligations (including the Termination Fee)
     which have accrued prior to or simultaneously with the termination
     of this Agreement.
