This Service Schedule is part of and is governed by the Master Agreement for
Internetworking Services ("Master Agreement").  The terms and conditions of the
Master Agreement are incorporated herein by reference.

1.  Covered Services.  We will provide you with the DiaLinx(TM) Basic Services
and Enhanced Services ("DiaLinx Service") indicated in the applicable GTE
Internetworking Service Quotation ("Quotation") which is attached hereto or
which we may provide to you in the future for additional DiaLinx Service.  The
term of the Service Period is one year or longer, as selected by you, and the
corresponding fees are described in the Quotation.  Our commencement of

prior to the expiration of the then-current Service Period to renew the DiaLinx
Service for an additional term of one (1) year or greater.  If the Service
Period expires before it has been renewed in writing, then we may continue to
provide you with the DiaLinx Service on a month-to-month basis, at our then-
current  undiscounted list prices, until the Service Period has been renewed in
writing.

4.  Minimum Customer Commitment.  You agree to the Minimum Customer
Commitment(s) for each period as set forth in the Quotation.  You agree that you
are obligated to pay the greater of your actual usage or the Minimum Customer
Commitment for the applicable period.

5.  Third Party Access.  Subject to the terms and conditions of this Service
Schedule, you have the non-exclusive right to authorize access to DiaLinx
Services to your employees and/or to any third party (including the right to
sell such DiaLinx Service).  You agree that if you offer DiaLinx Service other
than to your bona fide employees, you will do so only pursuant to a binding
agreement incorporating terms substantially similar to those stated in Section
14 (Mandatory Flow-down Terms) of this Service Schedule.

6.  Responsibility for End Users.  You agree to be responsible for all billing
and collection from end users and that you will pay us on a timely basis,
regardless of whether you collect payment from end users.  You agree to be
responsible for all communications to and business relations with end users.
You shall be responsible for providing all technical and business support
related to DiaLinx Service access for end users, including but not limited to
responding to inquiries and questions, hot-line support, problem resolution,
providing system configuration, installation and support, as applicable and
other such services and shall maintain an organization which is highly trained
and qualified to provide such support.  You are responsible for authenticating
and authorizing access by your end users to DiaLinx Service.  Unless you have
purchased optional RADIUS hosting services from us, you shall install, operate,
and maintain a dedicated RADIUS server meeting the RADIUS specifications
published in Internet RFC 2138 and 2139 and all published derivative RFSs.  Our
RADIUS server will prompt each end user for the end user's identification and
password, and poll your RADIUS server for access information.  Unless otherwise
provided for in the Quotation, we will support only one authentication realm
(e.g. companyname.com).

and providing the telephone services and user modems necessary to access DiaLinx
Service.  In no event will we be responsible for end user telephone charges.

8.  Network Access Availability.  ACCESS TO THE DIALINX NETWORK CANNOT BE
GUARANTEED TO YOU OR YOUR END USERS.  END USERS MAY BE UNABLE TO ACCESS THE
DIALINX SERVICE AT ANY TIME AND DISCONNECTIONS MAY OCCUR FROM TIME TO TIME.  YOU

INCUR ARISING OUT OF THE USE OR INABILITY TO USE THE DIALINX SERVICE.  THIS
DISCLAIMER IS IN ADDITION TO, NOT INSTEAD OF, THE DISCLAIMER, LIMITATION OF
LIABILITY AND LIMITATION OF DAMAGES CONTAINED IN THE MASTER AGREEMENT.

9.  Regulatory Charges.  We shall flow through to you any local exchange carrier
(LEC) price changes (i) that are attributable to changes in Federal or state
regulation, or (ii) for Federally regulated services that are treated as
exogenous regulatory cost changes by the Federal Communications Commission (the
"FCC") under its price caps regulations as defined in the FCC Rules.  47 C.F.R.
Section 61.45.  For purposes of this paragraph, price changes attributable to
changes in regulation include, but are not necessarily limited to, price changes
reflecting total or partial elimination of any enhanced services provider
exemption from payment of interexchange access charges or any regulatory
decision which results in application of multiple Subscriber Line Charges to
ISDN Primary Rate interface circuits or channelized T1 circuits.

10.  Compliance with Laws and Content Responsibility.  You shall not use or
permit the DiaLinx Service to be used (i) in violation of any applicable export
laws (including without limitation any U.S. export laws); (ii) in violation of
any applicable national, state, or local laws or regulations, including without
limitation any laws governing the import of the DiaLinx Service, or governing
the content which may be available via the DiaLinx Service; (iii) in violation
of our acceptable use policy which is published on our web site at

http://www.bbn.com/sup/; or (iv) in ways that infringe the rights of others, or
-----------------------
interfere with other users of our network or other networks.  For example, you
shall not distribute chain letter or unsolicited bulk electronic mail
("spamming"); propagate computer worms or viruses; use a false identity; attempt
to gain unauthorized entry to any site or network; distribute child pornography,
obscenity or defamatory material over the Internet; or infringe copyrights,
trademarks or other intellectual property rights.  We reserve the right to
suspend or terminate the DiaLinx Service (or any portion thereof) without notice
in the event that we believe that your use (or any of your end user's use) of
the DiaLinx Service may be in violation of this section.  You acknowledge that
we have no control over or liability for the actions of local jurisdictions
which may restrict or block the DiaLinx Service.

11.  Currency and Taxes.  All payments shall be in U.S. Dollars.  You are
responsible for the payment of all taxes (including without limitation
applicable VAT or withholding taxes but excluding taxes based solely on our net
income), import duties, or other applicable telecommunications or regulatory
fees (collectively, "Taxes").  You shall not deduct any such Taxes from the
amounts owed to us.  In the

event you are required to withhold Taxes from any payment due to us, then the
amount of such payment shall be automatically increased to totally offset such
Taxes, so that the amount actually remitted to us, net of all Taxes, equals the
amount invoiced or otherwise due.

12.  Disputes.  Any dispute arising out of or in connection with the DiaLinx
Service in a country other than the United States, shall be referred to and
finally resolved by arbitration in accordance with the Rules of the
International Chamber of Commerce then in force; provided, however, that either
party may, at its sole discretion, seek injunctive relief in the courts of any
jurisdiction as may be necessary and appropriate to protect its proprietary or
confidential information.  The language used in the arbitral proceedings, and
the governing language of this agreement, shall be English.  Unless otherwise
mutually agreed upon in writing by the parties, the site of the arbitration
shall be Boston, Massachusetts, U.S.A.  Judgment upon the award of the
arbitration may be entered in any court having jurisdiction thereof.

13.  Governing Law.  The governing law in any dispute shall be the substantive
law of the Commonwealth of Massachusetts, U.S.A. without regard to conflicts of
law.  The parties expressly agree that the U.N. Convention on Contracts for the
International Sale of Goods shall not apply to the Agreement.

14.  Local Access Numbers.  We expect the DiaLinx network to change over time in
order to meet the needs of our customers.  We reserve the right to add to,
delete or change the dial-in access numbers associated with a specified service
category from time to time.  You will be notified of changes to the DiaLinx
network or access numbers via periodic e-mail updates.

We may periodically add additional dial up access service categories as the
DiaLinx network evolves.  These additional services and respective prices will
be made available on an ongoing basis, via e-mail updates notifying you of the
additional service.  Use of such additional services by you or your end users
will be deemed your acceptance of the updated service and pricing.  For a
current list of services, pricing, and dial up access numbers associated with
each service, please consult our Web page as listed in your DiaLinx Service
Description or contact your GTE Internetworking representative.

15.  Mandatory Flow-down Terms.  You agree to include terms  substantially
similar to the following minimum terms in legally binding agreements with end

"Network Services Supplier" shall mean us.  "Company" shall mean you.  "User"
shall mean the non-employee end user, and "Network" shall mean the dial-up
network operated and maintained by us; and "Services" shall mean the DiaLinx
Service:

No Right of Resale.  User may not resell or redistribute any Services.

----------------------
Services Supplier is responsible for the content of the transmissions which may
pass through the Network.  User agrees that it will NOT use the Services in ways

CAPACITY TO MEET THE DEMAND OF END USERS DURING SPECIFIC HOURS.  USER MAY BE

OCCUR FROM TIME TO TIME.  NEITHER COMPANY NOR ITS NETWORK SERVICES SUPPLIER WILL
BE LIABLE FOR UNAUTHORIZED ACCESS TO COMPANY'S OR USER'S TRANSMISSION FACILITIES
OR PREMISES EQUIPMENT OR FOR UNAUTHORIZED ACCESS TO OR ALTERATION, THEFT OR
DESTRUCTION OF USER'S DATA FILES, PROGRAMS, PROCEDURES OR INFORMATION THROUGH

Quotation for DiaLinx Service
This Quotation is for DiaLinx Service Version 2.1, and sets forth the pricing
and volume commitments agreed to under the Service Schedule for DiaLinx
Services.

1.      Recital: For ease of understanding, this section highlights the general
elements of pricing and commitments:

        1.1     Network Access. You will be billed for each user who may access
                the GTE Internetworking DiaLinx network ("Network"). Several
                pricing options are available to you regarding user usage. These
                options include [* Confidential Treatment Requested]

        1.2     Minimum Customer Commitment: In return for volume discounts
                (inherent in the prices stated below), you have agreed to use a
                minimum dollar volume of network access in each month of the
                agreement ("Minimum Customer Commitment") for each pricing
                realm. In the event that network access charges for a given
                realm do not meet the Minimum Customer Commitment, you will be
                billed for this minimum amount.

        1.4     Surcharge: You will be billed additional charges for user's use
                of the International or 800 or 888 dial access.

2.      Territory: The Territory for Network access shall be the Global DiaLinx
        Network.

3.      Commencement Date: The Commencement Date is the day on which you or a
        user first connect to the Network, whichever is earlier.

4.      Service Period: The Service Period shall be [* Confidential Treatment
        Requested] plus an initial period consisting of one (1) partial calendar
        month. Month zero (0) means the partial calendar month beginning on the
        Commencement Date. Month one (1) means the full calendar month
        immediately following the Commencement Date, etc.

5.      Minimum Customer Commitment: During the Service Period, in return for
discounts inherent in the pricing outlined herein, you have agreed to use a
minimum dollar volume of network access in each month of the agreement ("Minimum
Customer Commitment") for each pricing realm (as described in Section 6). In the
event that Network access charges for a given pricing realm do not meet the
Minimum Customer Commitment you will be billed for the difference between the
amount actually charged within the given month and the Minimum Customer
Commitment.

[* Confidential Treatment Requested]

6.   Rates and Charges: You have the following pricing options available for
     your users. A user is defined as a unique login ID. We reserve the right to
     prohibit multiple concurrent network sessions using the same login ID.

     U.S. Local Dial Access:

     [* Confidential Treatment Requested]

6.1  800/888 Surcharge: In addition to any other applicable charges, access to
     the Network via the U.S. 800/888 or Canadian 800/888 dial-up numbers will
     incur an additional charge per hour per user. Access via the U.S. 800/888
     dial-up numbers will incur [* Confidential Treatment Requested] per user
     for access via the Canadian-US 800/888 dial-up numbers.

6.2  ISDN Surcharge: Access via ISDN will be charged in accordance with the
     applicable realm pricing. [* Confidential Treatment Requested]

6.3  International Surcharges: In addition to any other applicable charges,
     access by to the Network via any Dialinx International Access Number will
     incur an additional charge per hour per user as detailed in the
     International Rate table below.

         International users will be billed a monthly International use for each
         month that a user accesses the DiaLinx International network, (much
         like a cellular phone "roaming fee"). If an individual user does not
         access the DiaLinx International network in any given month, no fee
         will be applied. Use of the Canadian 800/888 service is not a part of
         the DiaLinx International network.

         [* Confidential Treatment Requested]

     A list of dial-in access numbers associated with each DiaLinx International
     zone can be found at http://www.bbn.com/support/docs/intpops.xls. GTE
     Internetworking expects the DiaLinx network to change over time in order
     to meet the changing needs of our customers. We reserve the right to add
     to, delete or change the dial-in access number associated with a specified
     zone from time to time.
