COVAD/CNM ISP CUSTOMER AGREEMENT                                Dated:  12/31/98
- --------------------------------------------------------------------------------

Covad Communications Company ("Covad") is pleased to bring CNM Network
("Customer") this offer for Covad's TeleSpeed-SM- Service.  Covad's TeleSpeed
Service is a permanent virtual circuit using Digital Subscriber Line ("DSL")
technology and provides a high-speed telecommunications data service for
Customer's Internet access clients ("Clients").  The terms of this agreement are
as follows:

     -    Customer may place orders for Covad's TeleSpeed Services during the
          term of this Agreement. Customer shall pay for, and Covad shall
          install, Covad's TeleSpeed Services in accordance with and subject to
          the terms of this offer and Covad's procedures.
     -    Customer shall provide Covad with addresses, direct telephone numbers,
          work email address and other information required in the client order
          form at the online Customer Care Center for successful installation of
          Customer's Clients designated to receive Covad TeleSpeed service under
          the terms of this agreement ("Agreement").  Covad shall keep all
          Client information confidential.
     -    Customer understands and agrees that the installation and monthly
          charges for Covad's Customer TeleSpeed Circuits and Client TeleSpeed
          Circuits and related charges shall be as set forth in the attached
          Pricing Schedule.

1.   TERM OF CONTRACT. This Agreement has an initial term of two years (the
     "initial term") and will continue on a month-to-month basis thereafter. 
     After the initial term, either party may terminate this Agreement upon
     thirty (30) days notice.  Upon expiration or termination of this Agreement,
     Covad will maintain all of Customer's Customer and Client TeleSpeed
     Circuits already ordered and provisioned pursuant to this Agreement,
     provided that Customer continues to pay all monthly charges for those
     Circuits pursuant to Paragraph 4.  The obligations of Paragraphs 2, 4, 6,
     7, 11, 12, 13, 14, 15, 16, 17, 18 and 19 shall survive termination of this
     Agreement.

2.   DEFINITION OF CLIENT TELESPEED CIRCUIT.

     2.1  A Covad Client TeleSpeed Circuit is a digital data telecommunications
          service that consists of one private virtual circuit between a
          Client's premise and a Covad serving wire center that utilizes Digital
          Subscriber Line ("DSL") technology and is used by Customer and the
          Client for Internet access or other information services.  A Client
          TeleSpeed Circuit provides upstream and downstream maximum throughput
          rates that range from up to 144Kbps to 1.5Mbps.  The maximum
          throughput rate depends on such factors as the distance of the
          Client's premise from a Covad serving wire center and the quality of
          the copper telephone line serving the premise.
     2.2  Provision of a Client TeleSpeed Circuit does not include any Internet
          access service.
     2.3  Upon approval of Customer and the Client, Covad may provide additional
          private virtual circuits ("additional PVCs") over the same facilities
          that are used to provide any Client TeleSpeed Circuit pursuant to this
          Agreement.  These additional PVCs may be used by Covad, Client or
          another party to support a variety of services of the Client's
          choosing, including, but not limited to, any form of
          telecommunications, telecommunications services, or information
          services.
     2.4  The parties shall undertake commercially reasonable efforts to work
          with each other to meet Customer's needs for Covad's services.

3.   COVAD AS PREFERRED PROVIDER OF TELESPEED SERVICES.

     3.1  During the term of this Agreement, Covad shall be Customer's preferred
          provider of DSL technology access to subscribers in any of the
          following metropolitan markets (collectively, the "Preferred
          Markets"):

               Dallas
               Denver
               Atlanta
               Boston (including portions of NH)

               Los Angeles
               Miami
               New York Tri-State
               San Diego
               San Francisco Bay Area
               Seattle
               Washington DC Metro Area (DC, MD and VA)

     3.2  The Preferred Market Launch Date for a particular Preferred Market is
          the date of Customer's acceptance of the first DS1 or DS3 Customer
          TeleSpeed Circuit from Covad (as described in Paragraph 10.1) in the
          relevant Preferred Market.

     3.3  "Preferred provider" means that Customer in each Preferred Market
          shall on a commerically reasonable best efforts basis utilize Covad's
          TeleSpeed Services to fullfill orders from its clients for DSL
          service.  Customer shall check availability for service for a client
          utilizing Covad's web-based qualifying tool and if available within 30
          days, place the order with Covad.  If availability is not available,
          or availability of service is more than 30 days from the date the
          order is taken, Customer shall have the right to seek alternative
          service providers for said order.  Covad's status as a Preferred
          Provider is conditioned upon Covad providing service and pricing which
          is reasonably competitive with alternative providers.

4.   PAYMENT TERMS.  The rates and charges set forth in the attached Pricing
     Schedule will apply to Client and Customer TeleSpeed Circuits provided to
     Customer during the term of this Agreement.  In addition to the rates and
     charges listed in the Pricing Schedule, Covad will also bill all applicable
     Federal, state, and local mandated surcharges, fees, user's fees, universal
     service contributions, local or state telecommunications infrastructure
     fees, and taxes to Customer.  Covad shall mail an invoice to Customer by
     the first day of the month, prior to the month of service, at 1900 E. Los
     Angeles, 2nd floor, Simi Valley, CA 93065.  This monthly invoice also will
     contain any additional surcharges or cancellation fees as described in this
     Agreement.  Customer shall pay all charges within 30 calendar days of the
     date that Covad's monthly invoices are mailed. Unless otherwise specified
     in writing by Covad, all payments shall be made to Covad Communications
     Company and mailed to Accounts Receivable Dept., Covad Communications
     Company, 2330 Central Expressway, Santa Clara, CA 95050.

5.   PRICE PROTECTION AND VOLUME COMMITMENTS.

     5.1  PRICE PROTECTION. The rates and charges in the Pricing Schedule are
          being provided on the basis of the volume commitments set forth in
          this Agreement.  In the event Customer fails to meet any of the volume
          commitments set forth in this Agreement, Covad reserves the right to
          amend, modify, or adjust the Pricing Schedule of this Agreement to
          ensure that the prices and discounts offered to Customer match those
          offered to other customers with similar volume, terms and conditions. 
          If the list prices of the TeleSpeed Services provided by Covad are
          reduced at any time during the term of this Agreement, Customer has
          the option to receive those reduced prices, effective on the date in
          which they are made available to other Covad Customers. After the
          initial term, Covad and Customer will negotiate in good faith for
          renewals of term and volume pricing.  A minimum of 60 days notice will
          be provided in case of a price increase on Customer or Client
          TeleSpeed Circuits.

               month thereafter
               --------------------------------------------------------


     5.3  FAILURE TO MEET VOLUME COMMITMENT.  On each monthly billing date
          subsequent to the dates listed in Paragraph 5.2, if Customer has not
          met the appropriate volume commitment, Covad will include on the
          monthly bill an additional charge, calculated in in the following
          manner:
     
       (Monthly charge for a TeleSpeed 144 circuit listed in Pricing Schedule)
                                   -multiplied by-
                 [ (Appropriate Interim or Final Volume Commitment) -
        (Number of Client TeleSpeed Circuits in service as of billing date) ]

     5.4  Customer acknowledges and understands that the lack of facilities or
          other operational impediments may preclude or delay Covad's ability to
          provide any particular TeleSpeed Circuit in any particular market. 
          Customer will be relieved of the volume commitments set forth in this
          Agreement only if Covad is not able to provide its TeleSpeed Services
          from at least five hundred (500) central offices by December 31, 1999.
          In the event Covad terminates its service and ceases operation in any
          Preferred Market, Customer and Covad shall re-negotiate the volume
          commitment set forth in Section 5 of this Agreement within 30 days of
          any such service termination.

6.   LIMITED WARRANTY.  Covad warrants to Customer, subject to the limitations
     set forth below, that Covad's TeleSpeed services shall operate in
     substantial accordance with the terms of this Agreement during the term of
     this Agreement.  

     A.   Customer understands and acknowledges that the actual transmission
          speeds delivered by Covad may vary from the transmission speeds
          otherwise expected by Customer or its Clients based on such factors as
          the length and gauge of the line serving the Client and other
          operational characteristics of the facilities and equipment used by
          Covad. Covad's TeleSpeed Services are subject to the attached Service
          Level Agreement ("SLA").

     B.   Covad shall use commercially reasonable efforts to provide
          installation, repair and maintenance functions for Covad's TeleSpeed
          Services.  In the event that a Client experiences and promptly
          notifies Customer, who then promptly notifies Covad, of a substantial
          reduction in transmission speed or significant interruption of
          service, Covad will undertake, at no charge to Customer, commercially
          reasonable efforts to restore Client's TeleSpeed Service. Covad shall
          not be responsible for service issues concerning a Client's computer,
          network or software.

     C.   Customer understands and acknowledges and represents and warrants that
          it will inform its Clients that Covad's TeleSpeed Service does not
          provide 911 or other emergency and ancillary services conventionally
          available from incumbent local phone companies.

     D.   Customer shall provide first-level support for all of its Clients.
          Covad shall provide commercially reasonable second-level support.

     E.   Customer understands and acknowledges that Covad's TeleSpeed Service
          is limited to certain regions in the United States. Covad reserves the
          sole and exclusive right to determine the expansion of its service
          area, and the right to maintain and reconfigure its service.

     F.   Customer acknowledges and understands that the lack of facilities or
          other operational impediments may preclude or delay Covad's actual
          installation, repair and maintenance of Covad's TeleSpeed Service in
          any particular market and to any particular Client.

     G.   Covad will make reasonable efforts to provide five (5) business-day
          notification to Customer on Scheduled Network Maintenance.  Covad may
          interrupt its provision of service for maintenance and other
          operational reasons, without any compensation or notice to Customer
          other than described in the attached SLA.  Covad also reserves the
          sole and exclusive right to terminate its service in any area or cease
          operations with 60 days notice to Customer. 

     H.   This limited warranty shall not apply if:  (1) the Client's equipment
          has been subjected to unusual physical or electrical stress, misuse,
          neglect, accident or abuse, or damaged by any other external causes;
          (2) Covad's TeleSpeed Service or equipment has been repaired or
          altered by anyone other than Covad or Covad's subcontractors or
          affiliates, without Covad's express and prior written approval; (3)
          Covad's TeleSpeed Service or equipment has been improperly installed
          by someone other than Covad or Covad's subcontractors or affiliates;
          or (4) Covad's TeleSpeed Service or equipment is used in violation of
          applicable law or in violation of instructions furnished by Covad.

     I.   Warranty:  Inside Wire Customer TeleSpeed Circuit & Client TeleSpeed
          Circuit. All Covad-installed or repaired premise wiring is warranted
          to be free from defects for a period of 30 calendar days from the date
          of work completion. Covad may outsource inside wire installations.

     J.   Warranty: Equipment Client Premise Equipment. If the Customer
          purchases client premise equipment directly from Covad, the equipment
          will carry a manufacturer's warranty of one year beginning on the
          billing start date for the Covad service.   In the event that the
          equipment is determined to be faulty within this warranty period,
          Covad will mail the replacement equipment to the Customer to arrive
          within 3 business days.

     K.   Year 2000 Compliance:  Covad has taken active steps to assure that
          Covad's TeleSpeed Service is Year 2000 compliant.  Covad represents
          and warrants that the equipment, software, and systems it has
          purchased, developed or deployed to support its TeleSpeed services are
          Year 2000 compliant.  Customer acknowledges that Covad's TeleSpeed
          Service is also dependent on the systems of the local telephone
          companies and other carriers.  Covad cannot make any representations
          with respect to Year 2000 compliance of the systems of these other
          carriers. 

THE FOREGOING LIMITED WARRANTIES SHALL BE IN LIEU OF AND EXCLUDE ALL OTHER
EXPRESS OR IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION, WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR USE OR PURPOSE.

7.   LIMITATION OF LIABILITY.  Except as otherwise provided for in this
     Agreement, neither party shall have any liability to the other party for
     any special, incidental, or consequential damages of any kind, regardless
     of whether such damages are foreseeable by either or both parties.  

     Except as specifically provided in this Agreement , this agreement does not
     provide and shall not be construed to provide third parties, including any
     Client, with any remedy claim, cause of action or privilege.

     Covad will install, maintain, and provide Covad TeleSpeed services in
     accordance with Covad's Internet Service Provider Program Binder, which may
     be changed by Covad from time to time during the term of this Agreement,
     provided that no such change shall materially or adversely effect Customer.
     Customer acknowledges that it has received a copy of Covad's Internet
     Service Provider Program Binder prior to execution of this Agreement.

9.   ACCEPTANCE OF CLIENT TELESPEED CIRCUITS AND CPE.

     9.1  Client TeleSpeed Circuit. Covad considers an installation successful
          if the maximum throughput rate is equal to or greater than 80% of
          ordered service.  An email will be sent to Customer with the installed
          maximum throughput rates and the Client TeleSpeed Circuit to be
          billed. The Customer has a 3-business day acceptance period to cancel
          or change the installed service. If the Customer does not respond to
          cancel or change the service, Covad will assume the installation is
          successful. If the Customer decides to cancel the service, there will
          be no charge for installation and the equipment will be returned at no
          charge.  When TeleSpeed 144 is not ordered, but it is the fastest
          circuit that can be installed, the Customer may elect to keep the
          Covad supplied and installed client premise equipment in place (no

          additional installation required). The Customer may also elect to
          replace the equipment (Covad or Customer supplied) which may require a
          new installation (no charge to Customer) for TeleSpeed 144.

10.  BILLING START DATES.

     10.1 Customer TeleSpeed Circuit.  Billing for a Customer TeleSpeed Circuit
          will start upon Customer's acceptance of the DS1 or DS3 from Covad
          (the "billing start date").  If the Customer TeleSpeed Circuit is
          ready from Covad (including port configuration and the firm order
          commit date has passed) but the Customer is not ready to accept the
          circuit, Covad will begin billing for the Customer TeleSpeed Circuit.
          Covad will not assess the monthly charge listed in the attached
          Pricing Schedule for the first Customer TeleSpeed DS3 Circuit in each
          Preferred Market (the "first Preferred Market DS3") until Customer
          places orders for Fifty (50) Client TeleSpeed Circuits in that
          Preferred Market after the Preferred Market Launch Date.  Upon receipt
          of fifty (50) Client TeleSpeed Circuits in that Preferred Market,
          Covad will bill Customer 1/2 (on a prorated basis) of the monthly
          charge listed in the attached Pricing Schedule for the first Preferred
          Market DS3 up to the date in which Customer places its 251st order for
          Client TeleSpeed Circuits in that Preferred Market after the Preferred
          Market Launch Date.  Thereafter, Covad will bill (on a prorated basis)
          the full monthly charge for the first Preferred Market DS3.  All
          subsequent Customer TeleSpeed DS3 Circuits ordered and provided in the
          Preferred Market will be billed in full as described in the Pricing
          Schedule.


     10.2 Client TeleSpeed Circuit.  Billing for a Client TeleSpeed Circuit will
          start on the date that the service is successfully installed (the
          "billing start date"), unless the TeleSpeed service is rejected within
          the 3-day Acceptance period as defined herein.

11.  CANCELLATION AND RETURN POLICIES.

     11.1 Customer TeleSpeed Circuit.

          11.1.1    The Customer is required to give 30 calendar days notice to
                    Covad to disconnect the Customer TeleSpeed Circuit. All
                    Client TeleSpeed Circuits served in the relevant
                    metropolitan market must be cancelled prior to disconnecting
                    the Customer TeleSpeed Circuit.
          11.1.2    Customer will notify Covad of all cancellations in writing
                    (the "notice of cancellation").  Upon receipt of a notice of
                    cancellation, Covad will bill the circuit to the end of the
                    service date in addition to other charges described in this
                    Paragraph.
          11.1.3    The minimum initial term for each Customer TeleSpeed Circuit
                    will be one year, continuing on a month-to-month basis
                    thereafter.  Customer may order a longer initial term for
                    any particular Customer TeleSpeed Circuit.
          11.1.4    If Covad receives a notice of cancellation of a Customer
                    TeleSpeed Circuit within 60 days of the billing start date,
                    Customer will not incur any additional cancellation fee. 
                    Covad will NOT refund installation and monthly Customer
                    TeleSpeed Circuit charges incurred within this 60-day
                    cancellation period.

          11.2.1    Customer will notify Covad of all cancellations in writing
                    or email (the "notice of cancellation").  Upon receipt of a
                    notice of cancellation, Covad will cancel the Client
                    TeleSpeed Circuit within one business day.  Covad will bill

                    will be one year, continuing on a month-to-month basis
                    thereafter.  Customer may order a longer initial term for
                    any particular Client TeleSpeed Circuit.

                    TeleSpeed Circuit within the 3-business day Installation

                    installation only.
          11.2.4    If Covad receives a notice of cancellation of a Client
                    TeleSpeed Circuit within 60 days of the billing start date,
                    Customer will not incur any additional cancellation fee. 
                    Covad will NOT refund installation and monthly Customer
                    TeleSpeed Circuit charges incurred within this 60-day
                    cancellation period.
          11.2.5    If Covad receives a notice of cancellation of a Client
                    TeleSpeed Circuit more than 60 days after the billing start
                    date and during the first year after the billing start date
                    for that circuit, Customer will pay the Client TeleSpeed
                    Circuit Early Cancellation Fee listed in the Pricing
                    Schedule, unless Covad is notified in writing of service
                    inadequacies and fails to rectify these inadequacies within
                    5 business days of receipt of such notice.

     11.3 Customer Premises Equipment

          11.3.1    Client premise equipment purchased directly from Covad can
                    be returned to Covad if it is unused and in its original
                    packing within 30 days from Covad's original shipment date. 
                    A 25% equipment handling and restocking charge will be
                    charged to the Customer by Covad. Customer should call Covad
                    Customer Care/Order Administration to receive a Return
                    Materials Authorization (RMA) number and to ship the
                    equipment back to Covad (the Customer shall pay all shipping
                    charges associated with this return).

12.  COMMUNICATION. The Customer should refer to Covad's online Customer Care
     Center for the majority of communication to and from Covad. All
     communication from Covad related to Covad's TeleSpeed Services provided to
     Customer will be directed to the Customer. Scheduling of visits to the
     Client site will be done by the Customer in conjunction with Covad Customer
     Care. All information discussed and agreed to with the Customer will be
     available to the Customer in the online Customer Care Center.

13.  CONFIDENTIAL INFORMATION. Each party shall limit disclosure of the other
     party's confidential information to employees and contractors with a need
     to know. Neither party shall disclose confidential information of the other
     party to any third party. Nothing herein shall supercede the terms of any
     non-disclosure agreement signed by the parties.

14.  CUSTOMER REPRESENTATIONS AND RIGHTS.

     Customer represents and warrants that it will utilize Covad's TeleSpeed
     Services to provide Internet access and other services in accordance with
     applicable law. Nothing in this contract shall limit Customer's ability to
     provide or resell value-added, "enhanced" or "information" services to
     others that utilize telecommunications or telecommunications services
     provided to Customer by Covad pursuant to this Agreement.  However, at all
     times Customer will remain fully responsible for payment for such services
     ordered in addition to all other obligations of this Agreement.  Nothing in
     this Agreement may be construed to prevent Customer or an affiliate of
     Customer from ordering additional PVCs to any Client in order to support
     telecommunications or telecommunications services for a separate and
     additional charge.  The provision of such additional PVCs to Customer will
     be pursuant to a separate Agreement between Covad and the Customer. 

     Customer acknowledges that it shall not, in the ordinary course of its
     business, when using Covad's network services, be able to identify, and
     distinguish between, packet data transmissions that originate and terminate
     within the same state (intrastate transmissions), and those packet data
     transmissions that originate and terminate in different states (interstate
     transmissions), and acknowledges that it is impractical to identify,
     distinguish and measure its intrastate and interstate

     transmissions on Covad's network. Further, Customer estimates (on a good
     faith, rough-guess basis) that more than ten percent of all data packets
     transmitted on Covad's network, including those to and from the Internet,
     will consist of interstate transmissions.
     
     Nothing in Section 14 or any other provision of this Agreement shall limit
     or impede the ability of Customer to offer any services, including voice
     over IP, to Customer's clients which utilize the Covad TeleSpeed service.

15.  FORCE MAJEURE. Covad and customer shall not be responsible for any failure
     to perform any obligation or provide service hereunder because of any Act
     of God, strikes, work stoppage, equipment or facilities shortages,
     governmental acts or directives, war, riot or civil commotion, or any other
     force beyond Covad's and customer's, as the case may be, reasonable
     control.  Customer's and Covad's remedies are limited as set forth herein. 

16.  ENTIRE AGREEMENT; AMENDMENTS IN WRITING; SEVERABILITY.  This Agreement,
     which includes all Attachments and Schedules referenced herein, constitutes
     the entire Agreement between the parties concerning the subject matter
     hereof and supersedes any prior agreements, representations, statements,
     negotiations, understandings, proposals or undertakings, oral or written,
     with respect to the subject matter expressly set forth herein.  Any
     amendment or supplement to this Agreement shall be in writing. If any
     provision of this Agreement shall be held to be illegal, invalid or
     unenforceable, each party agrees that such provision shall be enforced to
     the maximum extent permissible so as to effect the intent of the parties,
     and the validity, legality and enforceability of the remaining provisions
     of this Agreement shall not in any way be affected or impaired thereby.  If
     necessary to effect the intent of the parties, the parties shall negotiate
     in good faith to amend this Agreement to replace the unenforceable language
     with enforceable language that reflects such intent as closely as possible.

17.  DISPUTE RESOLUTION AND CHOICE OF LAW.  The parties shall attempt to resolve
     any disputes between them prior to resorting to litigation.  Customer's
     remedies are limited as set forth herein.  Any dispute arising between the
     parties shall be governed by California law.

18.  ASSIGNMENT.  Customer may not assign or transfer the rights or obligations
     under this Agreement to any third person (excluding transfers incident to
     an acquisition or change in control of Customer) without the prior written
     consent of Covad.

19.  INTELLECTUAL PROPERTY.  Each party will continue to independently own its
     intellectual property, including all patents, trademarks, trade names,
     service marks, copyrights, trade secrets, proprietary processes and all
     other forms of intellectual property.  Any improvements to existing
     intellectual property will continue to be owned by the party already
     holding such intellectual property.  The parties agree to authorize use or
     cross-license intellectual property only to the extent necessary to meet
     their respective commitments of this Agreement.
