                    Application for Confidential Treatment]

                   Purchase, Resale and Marketing Agreement

This Purchase, Resale and Marketing Agreement ("Agreement") is executed this ___
day of _____________ 2000 by and between Genuity Inc. with principal offices at
3 Van de Graaff Drive, Burlington, MA  01083 ("Genuity") and Bell Atlantic
Corporation with its principal office at 1320 North Courthouse Road, 5/th/
Floor, Arlington, VA 22201 ("Bell Atlantic")

WHEREAS, Genuity provides data and IP services;

WHEREAS, the parties estimate that there is a multi-billion dollar market
opportunity for such services during the next five years;

WHEREAS, where permitted by applicable federal law, Bell Atlantic desires to
market and resell Genuity's data and IP services to its customers;

WHEREAS, Bell Atlantic estimates that it could achieve revenues in excess of two
billion dollars ($2,000,000,000.00) through the sale of such services within the
next five years;

WHEREAS, Genuity desires to have Bell Atlantic market and resell, and Bell
Atlantic desires to market and resell Genuity's IP and data services subject to
the terms and conditions of this Agreement.

NOW, THEREFORE, in consideration of good and valuable consideration, the
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:

1.  SALE AND MARKETING OF GENUITY SERVICES

1.1  Appointment.  Genuity hereby authorizes Bell Atlantic and those Bell
     -----------
Atlantic affiliates who place orders hereunder ("Authorized Affiliate(s)")
during the term of this Agreement to purchase either for their own use, to use
in providing services to their customers, and/or to market and resell those
Genuity services defined in the Service Schedules attached hereto (collectively,
the "Genuity Services") to end users ("End Users") located in all geographic
areas where Genuity offers the Genuity Services and where Bell Atlantic may
lawfully offer the Genuity Services ("Territory").  The Genuity Services shall
be provided by Genuity or a Genuity affiliate as identified in the applicable
Service Schedule.  An order for and the provision of a Genuity Service
establishes a contract between the Bell Atlantic or the Authorized Affiliate and
the Genuity-designated service provider for the Genuity Service under the terms
and conditions of this Agreement and the relevant Service Schedule.  Bell
Atlantic and/or an Authorized Affiliate may designate another Bell Atlantic
affiliate or third party to act as a sales agent for such Authorized Affiliate.
Bell Atlantic shall be responsible for coordinating its program for such third
party sales agents, including providing necessary support and training.  Bell
Atlantic shall indemnify Genuity for the actions of such third party agents as
set forth in Section 10.  Bell Atlantic's right to distribute and market Genuity
Services shall be further defined in each Service Schedule.  Such rights may
include the right to resell the Genuity Service as a standalone service, as part
of an integrated system or solution, or with value added services.  (For the
purpose of this agreement, the term "affiliate" shall mean, with respect to any
person, any other person directly or indirectly controlling or controlled by, or
under direct or indirect common control with, such person.)

1.2  Lead Referrals.  Bell Atlantic may in its discretion refer to Genuity any
     --------------
offers to purchase or orders for (i) Genuity Services, or (ii) other services
offered by Genuity.  Genuity may in its discretion refer to Bell Atlantic any
offers or prospective offers to purchase the Genuity Services.  Any such
referral shall be made in accordance with applicable federal law and Section 2.4
of this Agreement.  If either party makes such a referral, the referring party
shall not, without advance notice to the other, independently pursue sale of the
referred opportunity with the potential customer unless the other fails to
pursue such referral within a reasonable time.  Genuity and Bell Atlantic shall
develop, no later than sixty (60) days

                                                                               1
<PAGE>

following the Effective Date (as defined in Section 6.1 of this Agreement) a
mutually agreed upon lead referral program that includes a commission to be paid
by the party that completes a sale pursuant to a referral.

1.3  Non-Exclusivity.  Genuity reserves the right to market, distribute and sell
     ---------------
Genuity Services, directly or indirectly, within and outside of the Territory,
and nothing in this Agreement shall limit in any manner Genuity's marketing or
distribution activities, or its right to sell directly or appoint other dealers,
distributors, licensees or agents within or outside the Territory to sell the
Genuity Services.  Similarly, Bell Atlantic reserves the right to market,
distribute and sell, directly or indirectly, within or outside of the Territory,
services that compete with the Genuity Services.

1.4  Service Changes.  Except as otherwise provided in a Service Schedule,
     ---------------
Genuity reserves the right to modify, change or add to any of the Genuity
Services at any time, upon forty-five (45) days' notice to Bell Atlantic, and to
remove or discontinue any of the Genuity Services at any time, upon ninety (90)
days' notice to Bell Atlantic, provided that any such change, modification,
addition, removal or discontinuance shall be part of a general action by Genuity
with respect to the affected service and its retail and wholesale customers, and
shall not affect any Bell Atlantic End User contracts or valid Genuity quotes in
existence at the time of the Genuity notice.  Genuity specifically agrees to
continue to provide any Genuity Service and all related product support affected
by such change or discontinuance in accordance with the description of the
service and other terms and conditions in any Bell Atlantic End User contract
(provided that the End User contract is consistent with the Genuity Service
Description and other terms and conditions applicable at the time the contract
was signed) or valid Genuity quotes, for the duration of the term of such End
User contract or contract that results from such quote.

1.5  Service Schedules.   Each Service Schedule shall, at a minimum, include:
     -----------------
(i) a description of the service, term, and pricing, (ii) the obligations and
responsibilities of each party related to the Genuity Service offered under the
Service Schedule; (iii) any required End User contract terms (i.e., mandatory
flowdown terms) that apply when Bell Atlantic markets or resells the Genuity
Service; and (iv) applicable service level agreements.

2.  RELATIONSHIP OF THE PARTIES

2.1  Independent Contractors.  The relationship of Genuity and Bell Atlantic is
     -----------------------
that of independent contractors, and nothing contained in this Agreement shall
be construed to: (i) give either party the power to direct and control the day-
to-day activities of the other, (ii) constitute the parties as partners, joint
ventures, co-owners, or otherwise as participants in a joint or common
undertaking, (iii) create a relationship of principal and agent, or (iv) allow
either party to create or assume any obligation on behalf of the other except

2.2  No Authority to Bind.  Each party acknowledges and agrees that it has
     --------------------
neither express nor implied authority to accept orders or enter into or modify
contracts, whether oral or written, on behalf of the other party.  Except for
the Genuity Services or as may be specifically set forth in other agreements
between the parties, Bell Atlantic shall not represent that any products and
services marketed, offered, or sold by Bell Atlantic are approved or endorsed by
Genuity in any way.

2.3  Actions by the Company, its Employees and Agents.  Each party shall be
     ------------------------------------------------
solely responsible for the acts and omissions of its employees, agents, and
contractors, including, without limitation, all labor costs and expenses.

2.4  InterLATA Services.  Bell Atlantic shall not provide or jointly market with
     ------------------
Genuity a Genuity Service that is, or includes as a necessary, bundled
component, an interLATA service in a state until Bell Atlantic has obtained any
necessary authorizations or approvals to do so.

3.  GENUITY RESPONSIBILITIES

3.1  Provision of Services.  Genuity shall provide the Genuity Services to Bell
     ---------------------
Atlantic and/or to End Users at the rates and in

                                                                               2
<PAGE>

accordance with the Service Descriptions and other specifications set forth in
this Agreement and the Service Schedules. Genuity shall also provide to Bell
Atlantic training, marketing assistance, support, equipment and software and
other ancillary services and products as may be set forth in the Service
Schedules and this Agreement.

3.2  Operations.
     ----------

(a)  Genuity shall provide Bell Atlantic with mechanized, electronic access and
interfaces to those Genuity systems that support Bell Atlantic's marketing,
provisioning and support of the Genuity Services to End Users. This access and
interface capability shall apply to the following information and functionality:
(i) pre-sales information; (ii) ordering and provisioning; (iii) new products
literature; (iv) problem identification and isolation to assist Bell Atlantic in
its provision of level one End User support; (v) repair/trouble ticketing; and
(vi) billing feeds, as appropriate, to the Genuity Services. Such access and
interfaces shall be provided in accordance with the implementation schedule set
forth in this Section 3.2. Genuity shall be solely responsible for the all costs
incurred for system development and implementation necessary to comply with this
Section 3.2. Genuity may recover the cost of such development and implementation
through the prices it charges all customers for the Genuity Services, but shall
not otherwise charge Bell Atlantic any portion of such costs.

(b)  Promptly following the Effective Date, Genuity and Bell Atlantic shall each
designate by written notice a senior operations point of contact (O-POC) for
developing, implementing and maintaining business process interfaces throughout
the areas of each party's business affected by this Agreement. The parties shall
oversee the rollout of transaction processes for quotes, orders, provisioning,
customer care and billing across all Genuity Services. The shared design
principles shall be integration across all Genuity Services, customer
responsive, web based, scalable, and minimization of manual intervention. A
written process architecture shall be developed and maintained by both parties.
The first copy of this architecture shall be finalized within one hundred twenty
(120) days after the Effective Date. This shall be a dynamic document, available
online to both parties, that shall be the basis for identifying improvement
opportunities and for operations plans. The parties shall perform quarterly
reviews of these plans, with the O-POCs jointly managing the agenda and
attendees for such reviews. These reviews shall be alternately hosted by each
party at its facility of choice. Genuity shall work with Bell Atlantic to
develop and implement new support tools and process improvements with respect to
Bell Atlantic's purchase and sale of the Genuity Services. Genuity shall retain
all rights to tools and processes it develops, and, at its option, may implement
these tools and processes for other customers and resellers.

(c)  Bell Atlantic shall be responsible for the End User relationship. Genuity
shall provide access to documentation, training materials, and on-line support
tools that facilitate Bell Atlantic in providing level one support services for
its End Users. At Bell Atlantic's request and at Genuity's expense, Genuity
shall provide one time "train the trainer" sessions for level one support for
each product or service. These training sessions shall be held at Genuity
facilities for class sizes not to exceed 12 people, at mutually agreed times.
Bell Atlantic shall pay travel and living expenses for its attendees. At Bell
Atlantic's request, Genuity shall provide to Bell Atlantic quotes for fees on a
daily basis (plus travel and living expenses) for subsequent "train the trainer"
sessions, which sessions shall be held at Bell Atlantic facilities. Genuity
shall provide such subsequent sessions upon Bell Atlantic's acceptance of such
quote(s).

(d)  Genuity shall provide at its expense level two and level three support for
the Genuity Services. Bell Atlantic shall provide at its expense level one
support for the Genuity Services it resells. For maintenance of Genuity-supplied
customer premises equipment, Genuity shall act as service agent for Bell
Atlantic on Level II and Level III support situations. This service and support
shall be Bell Atlantic branded where practical. Genuity shall work cooperatively
with Bell Atlantic and/or Bell Atlantic customers for identification/isolation
of

                                                                               3
<PAGE>

difficult end-to-end or otherwise elusive problems. Genuity shall assume all
escalation and interface responsibilities for its suppliers.

(e)  The parties shall agree upon and publish written Bell Atlantic and Genuity
escalation and communication paths for the Genuity Services. These documents
shall be an addendum to the business process architecture discussed above.

(f)  Bell Atlantic and Genuity shall establish an operations review process to
review the performance measurements under the service level agreements for each
Genuity Service on a monthly basis, and establish action plans and "next steps"
as appropriate. These monthly reviews may be conducted by telephone or in face-
to-face meetings.

3.3  Business Practices.  Genuity and Genuity's representatives and employees
     ------------------
shall at all times give prompt, courteous and efficient service to End Users it
has contact with pursuant to its obligations under this Agreement, or otherwise
on behalf of Bell Atlantic.  Both parties shall follow all End User interface
procedures set forth in a Service Schedule and/or developed and agreed upon by
the parties.

3.4  Training Support.  Genuity shall specify the level of training required to
     ----------------
sell and support the Genuity Services.  Genuity shall make available, at its
expense (other than travel and lodging expenses for Bell Atlantic employees)
training support materials and training for the Genuity Services that is
substantially equivalent to the training Genuity provides to its internal sales
force (excluding Genuity-proprietary content such as strategic planning,
internal sales discussions, Genuity market focus, Genuity customer specific
information, and similar content) and is sufficient to qualify Bell Atlantic
employees to provide the necessary technical expertise to design where
applicable (on a pre-sale basis), sell and support the volume and type of
Genuity Services which Bell Atlantic has forecast.  This training shall be made
available initially for a reasonable number of Bell Atlantic sales personnel, as
mutually determined by the parties.  Genuity shall make subsequent training
available for new Genuity Services and significant enhancements to the services,
and periodically during the term of this Agreement (no more frequently than once
each calendar year) for a reasonable number of new sales personnel.  Additional
training required by Bell Atlantic shall be provided by Genuity at Bell
Atlantic's expense, at a price not to exceed Genuity's reasonable costs of
providing the training.  The parties shall develop a training support plan
within ninety (90) days of the effective date of this Agreement.

3.5  Marketing Support. Genuity shall reasonably assist Bell Atlantic in Bell
     -----------------
Atlantic's marketing and provision of the Genuity Services to End Users
identified by Bell Atlantic.  The parties shall develop procedures and
guidelines for such marketing support within ninety (90) days following the
Effective Date.  Such assistance shall include making sales support and
technical experts reasonably available for consultation with Bell Atlantic and
the End User.  At Bell Atlantic's request, Genuity shall provide qualified sales
and/or technical support individual(s) to accompany Bell Atlantic on sales calls
End Users. In such joint presentation to an End User, Bell Atlantic shall
determine whether the proposed service shall be identified as a co-branded
offering. Genuity's sales support and technical personnel who work on End User
accounts associated with Bell Atlantic marketing activities shall not
concurrently provide services pertaining to that End User to either Genuity's
internal sales channels or any other reseller of Genuity.  Any information about
the End User, to include the identification of the sales opportunity, that is
provided by Bell Atlantic, or that is developed by Genuity in its support of
Bell Atlantic's sales efforts, shall be Bell Atlantic Confidential Information.
In providing business and marketing support to Bell Atlantic pursuant to this
Section 3.5, Genuity shall not sell or attempt to sell the products or services
of any party other than Bell Atlantic, provided, however, that Genuity may,
                                       -----------------
while providing such support and in consultation with Bell Atlantic, make
recommendations to End Users regarding other Genuity Services available from
Bell Atlantic.

3.6  Availability of Services and Support.
     ------------------------------------

                                                                               4
<PAGE>

(a)  Genuity shall provide to Bell Atlantic the same type and quality of Genuity
Services (including, without limitation, Service Descriptions, service level
agreements and remedies, geographic availability, and support) as Genuity
provides to other resellers and to its own internal sales channel and retail
customers. Genuity shall modify the Genuity Services and add new Genuity
Services as reasonably necessary to keep the portfolio of Genuity Services
(including, without limitation, Service Descriptions, service level agreements
and remedies, capacity availability in the Territory, and support) available
under this Agreement competitive and current with comparable services available
from other suppliers. Genuity shall not reduce the geographic coverage of a
Genuity Service existing as of the date the parties executed this Agreement.
Subject to the foregoing, Genuity shall be the sole determiner of its services
portfolio and its market strategy, including the market segments upon which it
shall focus and the levels of investment it shall make in particular services or
market segments, or the geographic locations in which it will offer the Genuity
Services.

(b)  Genuity shall keep Bell Atlantic informed about new service offerings and
significant product enhancements, and shall offer any new services and service
enhancements to Bell Atlantic so that Bell Atlantic may market such new services
or enhancements to End Users on as timely a basis as Genuity's internal sales
channel or Genuity's other resellers or sales agents. In the event that Bell
Atlantic has information that one or more of the Genuity Services are not
competitive in the market, Bell Atlantic shall provide evidence thereof to
Genuity and Genuity shall review this information and meet with Bell Atlantic to
provide Genuity's response to Bell Atlantic's information.

(c)  Within ninety (90) days of the Effective Date, the parties shall develop a
benchmarking process to track prices and related terms for services comparable
to the Genuity Services for the purpose of administering this Section 3.6.

3.7  Availability of Competitive Terms and Prices For Individual Customer
     --------------------------------------------------------------------
Requests
--------

(a)  Bell Atlantic may request that Genuity provide reduced prices or discounts,
different terms, or changed Service Descriptions ("Custom Bids") for purposes of
responding to individual End User requests for proposals or negotiation with the
End User. When Bell Atlantic has quoted Genuity Services and the End User has
requested a Custom Bid, Bell Atlantic shall as soon as possible consult with
Genuity regarding such requests. Genuity agrees to give good faith consideration
to such requests, to offer such changes as Genuity determines it is willing to
make and to respond to Bell Atlantic within the timeframes of the individual
transaction which has generated such request. Bell Atlantic may obtain offers of
services comparable to, or as reasonable substitutes for, Genuity Services from
third parties. Where prices and/or other terms for such services are both
responsive to the particular customer request and more favorable to Bell
Atlantic than the prices and/or terms for Genuity Services, Bell Atlantic may
notify Genuity that it has received offers that include such favorable prices
and terms and request Genuity to meet such prices and terms. Genuity shall
respond within the timeframes of an individual sales transaction as requested by
Bell Atlantic. The parties agree to establish procedures under which such
requests shall be handled, no later than ninety (90) days after the Effective
Date, and to add such procedures as a schedule to this Agreement. Genuity shall
treat information concerning price reductions and other information requested as
Confidential Information of Bell Atlantic. Bell Atlantic shall treat Genuity's
response, including any information developed by Genuity and provided to Bell
Atlantic regarding pricing and other competitive information, as Confidential
Information of Genuity and shall not provide such information to any third party
other than in connection with providing a bid to the End User or as otherwise
permitted by this Agreement.

(b)  Genuity shall be obligated to provide Custom Bids to Bell Atlantic with
respect to a Genuity Service where Genuity customarily provides such Genuity
Service to other customers on a custom basis. In situations not covered by the
preceding sentence, Genuity

                                                                               5
<PAGE>

shall not be obligated to respond to Bell Atlantic requests for Custom Bids to
the extent they exceed twenty percent (20%) of the quotes requested by Bell
Atlantic for a particular Genuity Service in a calendar quarter.

3.8  Proposal Materials.  Unless otherwise agreed by Bell Atlantic, all sales
     ------------------
collateral, proposals, contracts and related proposal documents for Genuity
Services covered by this Agreement and marketed by Bell Atlantic shall be
prepared and presented by Bell Atlantic, using Bell Atlantic letterhead and
other indicia.  Genuity shall provide content that may be used without Genuity
identification, as requested by Bell Atlantic.  Bell Atlantic agrees to take all
reasonable steps necessary to protect Genuity's intellectual property rights in
such content, including reproducing all copyright notices, if any.  Bell
Atlantic further agrees that Genuity shall retain all rights in such content.
If the End User indicates interest in Genuity services that are outside the
scope of the Genuity Services, Genuity shall coordinate with Bell Atlantic
before making a proposal for such services.  Genuity may submit proposal
materials and customer contracts for such other services using Genuity
letterhead, forms and indicia.

3.9  Return of Materials.  Upon request from Bell Atlantic, Genuity shall return
     -------------------
or destroy all materials provided by Bell Atlantic related to any proposal
development or other marketing activity pertaining to an End User identified by
Bell Atlantic.  In such event, Bell Atlantic shall return to Genuity or destroy
all proposal development or marketing material Genuity has provided to Bell
Atlantic relating to such End User.

4.  OBLIGATION OF BOTH PARTIES

4.1  No Disparaging Conduct.  Neither party shall do anything that would tend to
     ----------------------
discredit, dishonor, reflect adversely upon, or in any manner injure the
reputation of the other party or any affiliate.  This provision shall not,
however, prevent either party from marketing competing services of either itself
or other entities.

4.2  Identification with a Party.  Representatives of a party shall not
     ---------------------------
represent themselves as employees of the other party in contacts with End Users
or others.

5.  BELL ATLANTIC OBLIGATIONS

5.1  Sales.  Bell Atlantic is authorized to sell the Genuity Services in the
     -----
Territory.  Bell Atlantic may not market or sell the Genuity Services to End
Users located outside of the Territory without the prior written consent of
Genuity.

5.2  Bell Atlantic End User Support.  Unless otherwise addressed in a Service
     ------------------------------
Schedule or in this Agreement, or separately agreed between Bell Atlantic and
Genuity, Bell Atlantic shall provide pre- and post-sales support to End Users.

     ---------------

<PAGE>

protective of Genuity as the mandatory flowdown terms specified in the
applicable Service Schedule.

5.8  Order Forecasts, Bell Atlantic shall provide Genuity with calendar
     ---------------
quarterly forecasts no later than the first day of the calendar quarter.  The
forecast shall reflect anticipated demand for the Genuity Services for the next
eighteen (18) months by volume for each Genuity Service and shall reflect, if
the information is available, the anticipated geographic areas where the Genuity
Services shall be sold.  Genuity shall treat the forecasts as Bell Atlantic
Confidential Information. Within sixty (60) days following the Effective Date of
this Agreement, the parties shall develop mutually agreed upon detailed
forecasting requirements for each Genuity Service that shall be set forth as
supplements to the applicable Service Schedules. The parties agree to work
together to make the forecasting process a mutually beneficial business
arrangement that supports each party's planning.  Bell Atlantic shall make
reasonable efforts to provide Genuity with the most complete and accurate
forecast information possible for Genuity to effectively plan service
availability.  Reasonable efforts shall be made by Genuity to make the Genuity
Services available to meet Bell Atlantic's forecasts.

6.  TERM AND TERMINATION

6.1  Term.  This Agreement shall take effect on the date on which, pursuant to
     ----
their Agreement and Plan of Merger, Bell Atlantic Corporation and GTE
Corporation cause a Certificate of Merger to be executed, acknowledged, and
filed with the Secretary of State of New York as provided in New York
Corporation Law, Section 907 ("Effective Date"), and unless terminated earlier
as provided herein, shall continue for a period of five (5) years thereafter
(the "Initial Term").  The Agreement shall then renew for successive one (1)
year renewal terms ("Renewal Term") unless either party provides the other with
notice at least sixty (60) calendar days prior to the end of the Initial or
Renewal Term of its intent to allow this Agreement to expire at the end of the
current term.  Upon expiration of this Agreement, in the event a Service
Schedule or Schedules has or have a term ("Service Schedule Term") that
extend(s) beyond the Initial or Renewal Term, as applicable, the Term shall be
automatically extended and remain in effect until such time as all such Service
Schedule Terms have been completed.

6.2  Termination for Default.  Either party may terminate this Agreement, and/or
     -----------------------
one or more Service Schedule if the default applies to such Service Schedules,
without liability to the other party immediately by written notice in the event
the other party (i) materially breaches this Agreement and fails to cure such
breach within thirty (30) days following written notice thereof, provided,
however, that if such breach cannot reasonably be cured during that time, the
defaulting party must use reasonable commercial efforts to cure such breach as
soon as practicable but in any event within ninety (90) days, (ii) engages in
fraud, criminal conduct or willful misconduct in connection with the business
relationship of the parties, or (iii) becomes insolvent, becomes involved in any
liquidation or termination of its business, is adjudicated as bankrupt or
effects an assignment for the benefit of creditors.  In the event Bell Atlantic
elects to terminate this Agreement pursuant to this Section, Genuity shall
continue to provide the Genuity Services to any existing Bell Atlantic End Users
receiving Genuity Services under a valid End User contract with Bell Atlantic as
of the effective date of such termination provided however, that Genuity shall
have no obligation to provide services to any such End User beyond the then
current term of the End User's contract with Bell Atlantic.  The parties shall
negotiate in good faith with respect to any additional Genuity Services that
Bell Atlantic may wish to acquire after the effective date of such termination,
but Genuity shall have no obligation to agree to provide such services to Bell
Atlantic. In the event Genuity terminates this Agreement pursuant to this
Section, Bell Atlantic agrees to cooperate with Genuity and perform the same
obligations described in Section 6.3 below to effect the transition of all
outstanding End User agreements for the services to Genuity.  Bell Atlantic
shall provide its assistance at no charge to Genuity.

                                                                               7
<PAGE>

6.3  Early Termination by Bell Atlantic.  In the event a legislature, regulatory
     ----------------------------------
agency, court or other governmental entity, by act or omission, materially and
adversely changes the rights, obligations or risks of Bell Atlantic with respect
to the sale of the Genuity Services, then Bell Atlantic may terminate this
Agreement or any Service Schedule without liability by providing at least ninety
(90) days advance written notice thereof to Genuity.  In such event, to the
extent permitted by the End User, Bell Atlantic shall provide Genuity with
copies of all End User agreements for the affected Genuity Service(s) and other
End User information and shall cooperate to effect an orderly and seamless
transition to Genuity of all outstanding End User agreements for affected
Genuity Services (including the assignment to Genuity of such agreements).  Bell
Atlantic shall reimburse Genuity for reasonable out-of-pocket costs incurred
with respect to such transition.  Genuity shall not be required to assume an End
User agreement if it does not contain a mandatory flowdown provision or contains
other terms and conditions that are materially different from Genuity's standard
terms and conditions and if Genuity and Bell Atlantic are unable, despite
reasonable efforts to amend such  agreements to add such mandatory flowdown
terms.  Notwithstanding the foregoing, where Genuity has designated pursuant to
Section 1.1 a Genuity service provider that is a private carrier for the
provision of capacity services (e.g., private line and ATM), then Genuity's
obligations under this Section 6.3 with respect to the affected End User
agreements shall be limited to Genuity using commercially reasonable efforts to
arrange for another reseller of the Genuity Services to assume such End User
agreements, provided, however, that Genuity may itself assume some or all of
such End User agreements.

6.4  Effect of Expiration.  At Bell Atlantic's request, upon expiration, Genuity
     --------------------
shall (i) use commercially reasonable efforts in making an orderly and seamless
transition of End Users from the Genuity Services to other services that Bell
Atlantic may choose to offer such End Users; and (ii) continue providing the
Genuity Services to Bell Atlantic as necessary to complete the then-current term
of each End User contract that extends beyond such expiration or termination.

6.5  Use of Program Materials Upon Termination.  Except for any use that may be
     -----------------------------------------
necessary to perform its obligations under any existing End User agreements,
Bell Atlantic shall, upon termination or expiration of this Agreement,
immediately cease the use of all Genuity program materials and the Genuity marks
related to the affected Genuity service and Bell Atlantic shall cease to
represent itself as a Genuity reseller for the affected Genuity Service.  Bell
Atlantic shall return to Genuity all material previously provided by Genuity to
Bell Atlantic.

7.  PRICING; PAYMENT TERMS; MINIMUM ORDER

7.1    Purchase Price. The price for each of the Genuity Services is set forth
       --------------
in the applicable Service Schedule.  Some Genuity Services may include
installation fees, usage fees and telco circuit connection and cancellation
fees.  To the extent Genuity is unable to identify such fees in the Service
Schedule or at the time an order is placed, it shall provide Bell Atlantic with
a good faith estimate thereof and notify Bell Atlantic as soon as it becomes
aware of the amount of such fees.  Genuity shall pass through such fees to Bell
Atlantic at the cost and shall use commercially reasonable efforts to obtain the
lowest cost.  Such prices, including the above mentioned fees and costs,
constitute the totality of charges for which Genuity may bill Bell Atlantic in
connection with the purchase of the Genuity Services and performance of its
obligations under this Agreement; no other charges (except for taxes as
permitted below) shall appear on any invoice to Bell Atlantic unless otherwise
agreed upon in writing by the parties.

7.2    Minimum Order.  Any minimum purchase commitment applicable to individual
       -------------
Genuity Services shall be set forth in the applicable Service Schedule.

7.3    Volume Purchase Commitment. In consideration of the performance
       ---------------------------
commitments

                                                                               8
<PAGE>

and other promises of Genuity as set out in this Agreement, Bell Atlantic agrees
to purchase the Genuity Services in the dollar volumes as set out in Attachment
1 (the "Purchase Commitment") or pay to Genuity the amounts described therein in
the event it fails to satisfy the Purchase Commitment.

7.4  Most Favored Customer.
     ---------------------

(a)  The Multiple Services Discount (as defined in the pricing attachments
hereto) offered to Bell Atlantic under this Agreement shall be at least as
favorable to Bell Atlantic as any Multiple Services Discount, or any similar
discount, offered, to any other non-government customer of the Genuity Services
who has made a comparable or lower purchase or volume commitment for the Genuity
Services under similar financial terms and conditions.

(b)  The individual Genuity Service Baseline Pricing and Volume Discounts (as
such terms are defined in the pricing attachments hereto) offered to Bell
Atlantic for each of the Genuity Services (other than Genuity Services that are
customized for Bell Atlantic pursuant to Section 3.7) available under this
Agreement will be at least as favorable to Bell Atlantic as the pricing and/or
discounts offered to any other non-government customer of the Genuity Services.

(c)  Exclusions:  The foregoing subsection (b) shall not apply to:

(1)  Discounts offered for Genuity Service(s) (or service components) to a
customer that are offset by lesser discounts on other Genuity Service(s) (or
service components) such that, given such customer's purchase commitments for
such Genuity Services, Bell Atlantic's discounts in aggregate are more
favorable;

(2)  Discounts are offered in good faith in exchange for corresponding (and
quantifiable, if practicable) value from a customer (e.g., in settlement of a
claim, in exchange for marketing or advertising, in consideration of customer-
unique cost reductions, etc.); provided, however, that in the event such
consideration could reasonably apply to Bell Atlantic and Genuity, then Genuity
shall offer such discounts along with the corresponding terms and conditions
reasonably and economically required to offer such pricing, in accordance with
section (d), below;

(4)  Discounts offered by Genuity on an exceptional basis resulting in pricing
with no margin for the purpose of securing strategic accounts; or

(5)  Discounts or pricing offered for beta tests or pilot programs that are
significantly limited in time and scope, in error, for charitable or promotional
purposes; or for any de minimus contracts (less than $24,000 per year in
aggregate per customer or affiliate).

(d)  Process. Genuity will give Bell Atlantic written notice (in accordance with
this Agreement) of any more favorable discounts and/or pricing offered to
another buyer pursuant to sections (a) or (b) above, within thirty (30) days of
execution of a service agreement between Genuity and such buyer. Within thirty
(30) days of receipt of such notice from Genuity, Bell Atlantic shall provide
Genuity with written notice in accordance with this Agreement of whether it
accepts such prices. If Bell Atlantic accepts such prices, this Agreement shall
be amended accordingly by a writing that is signed by the parties, and such
prices shall be deemed to apply as of the date the same were first offered to
such buyer. If a credit is due Bell Atlantic as a result of the application of
such prices, then Genuity shall either apply the resulting credit to Bell
Atlantic's account on the next invoice sent by Genuity to Bell Atlantic, or
refund the amount to Bell Atlantic, at Bell Atlantic's election.

7.5  Payment Terms.  Payments by Bell Atlantic in consideration of provision of
     -------------
Genuity Services by Genuity in accordance with this Agreement are due in United
States dollars in the United States net thirty (30) calendar days from receipt
of a valid and complete invoice.  In the event Genuity has not received payment
from Bell Atlantic within forty-five (45) days from the date of issuance of the
invoice by Genuity, and Bell Atlantic has not disputed the

                                                                               9
<PAGE>

invoice pursuant to the terms of Section 7.7, Genuity may, without limiting its
remedies at law or equity for any default, upon thirty (30) days written notice
to Bell Atlantic, suspend service to the End User for the affected service, if
Bell Atlantic has not within this period provided payment; provided, however,
that Genuity shall give Bell Atlantic written notice at least fifteen (15) days
in advance of taking such action which shall identify the End Users to whom
Genuity proposes to suspend service.

7.6  Interest on Overdue Amounts.  Genuity may charge Bell Atlantic interest at
     ---------------------------
the lower of 1.5% per month or the highest monthly rate permitted by law on all
invoiced amounts that are not in dispute, as provided in Section 7.7, below, for
which payment has not been received by the due date of such invoice.

7.7  Disputed Invoices.  In the event Bell Atlantic disputes an invoice issued
     -----------------
by Genuity for services performed under this Agreement, Bell Atlantic may, no
later than the due date of the invoice, notify Genuity in writing of such
dispute.  Such notice shall identify and describe in detail the basis for such
dispute.  Within thirty (30) days of the receipt of such notice by Genuity,
Genuity shall either correct the invoice, resolve the dispute, or respond in
writing to Bell Atlantic providing specific reasons why the invoice is correct.
If, within forty-five (45) days of the date of Genuity's response, the dispute
is not resolved, Bell Atlantic and Genuity shall each designate an executive to
meet and negotiate in good faith to resolve the dispute.  Bell Atlantic shall
pay any undisputed amount within the time frame noted in section 7.5, above, and
may withhold disputed amounts pending resolution of the dispute.  Within thirty
(30) days following the resolution of a dispute over an invoice, the party owing
an amount shall pay or credit the other the amount due.  Failure to raise a
dispute over an invoice in accordance with the procedures of this section shall
not prevent or prejudice Bell Atlantic in subsequently raising the matter.

7.8  Taxes and Duties.  Bell Atlantic shall be responsible for the payment of
     ----------------
any and all sales, value added, withholding or other taxes, duties, levies, fees
and other charges that are or may be imposed by any governmental entity based on
Bell Atlantic's sale of the Genuity Services to End Users.

8.  TRADEMARKS, TRADENAMES; PROPRIETARY RIGHTS

8.1  Co-Branded Genuity Services.  The Genuity Services and related customer
     ---------------------------
support services may be co-branded (e.g., "Bell Atlantic Web Hosting powered by
Genuity," etc.).  The form and content of such co-branding is set forth in the
Service Schedules.  Bell Atlantic may brand resold Genuity Services otherwise as
determined by Bell Atlantic, if Bell Atlantic makes no use of a Genuity name,
servicemark or trademark in association with the service.  Any co-branding shall
be in accordance with applicable federal law and Section 2.4 of this Agreement.

8.2  Trademark License. (i) Each party hereby grants to the other during the
     -----------------
Agreement Term a limited, nontransferable, and nonexclusive license, without the
right to grant sublicenses to use such party's Program Marks (as set out in the
Trademark Schedule or otherwise provided in writing) solely in connection with
the production and dissemination of co-branded marketing materials in the
Territory for the Genuity Services and in connection with co-branded customer
care materials for the Genuity Services to be performed by Genuity hereunder,
subject to the terms and conditions of this Agreement, to include compliance
with applicable federal law and Section 2.4 of this Agreement. (ii) Any and all
such materials using a party's Program Marks shall be developed in consultation
with that party, and shall not be publicly disseminated without the party's
prior written approval as to their form.  If a party at any time finds any
materials using its Program Marks to be deficient in quality or finds any
materials being marketed in a misleading or deceptive manner or otherwise in
violation of this Agreement, then it must notify the other in writing of such
deficiency, and the other party shall eliminate such deficiency within thirty
(30) days after receiving written notice.  A party shall have the right to
publish additional conditions and quality standards,

                                                                              10
<PAGE>

from time to time, as is necessary to protect its Program Marks, provided such
conditions and standards are imposed on other use of the same marks by that
party or any of its Affiliates. A party shall not, directly or indirectly,
license or attempt to license, whether orally or in writing, any other person to
use any of the other party's Program Marks, and, shall make no assignment of any
right to use the Program Marks. Any attempt to assign any right to use Program
Marks other than as contemplated hereby as well as any attempt to license
another person or entity to use the Program Marks shall result in immediate
cancellation of the license granted herein. A party shall not have any right,
title, or interest in and to the other's Program Marks, or in the registrations
or applications for registration thereof, except only the right to use the
Program Marks as specifically authorized by this Agreement. Each party
acknowledges that its use of the other's Program Marks shall not create in its
favor any right, title, or interest therein. Neither party shall use any
trademark, service mark, corporate name, business name, trade name or domain
name identical with or confusingly similar to the other party's Program marks,
except for the Program Marks and then only as expressly permitted by this
Agreement. Each party agrees that it shall never directly or indirectly
challenge, contest or call into question or raise any questions concerning the
validity or ownership of the other party's Program marks or any registration or
application for registration for the Program Marks of the other party. Neither
party shall use any of the other's Program Marks except in the graphic format
set forth in Schedule A-2, or as otherwise provided for herein. If a party
decides in its sole discretion to modify or discontinue the use of any of its
Program Marks, the other party shall refrain from using the unmodified or
discontinued marks, destroy all designs, stationery, promotional materials,
advertising or other materials of every kind using any of the unmodified or
discontinued marks, and to commence using the modified or substituted marks in
accordance with this Agreement as if such marks had been identified herein,
provided that the party so modifying or discontinuing its Program Marks shall
promptly reimburse the other for any and all costs and expenses it incurs in
connection with the reprinting of new documentation and materials for use in
connection with such Program Marks and such other costs as it shall reasonably
incur.

8.3  Ownership of Work Product. Subject to pre-existing rights as to elements
     -------------------------
incorporated in the co-branded marketing and customer care materials ("Work
Product"), each party shall have and retain all ownership rights (including,
without limitation, ownership of any copyrights) in the work product that it
creates, and prepares, and all such work product shall remain the exclusive
property of that party.  Each party's trade name(s), trademark(s), logo(s) and
icon(s) shall remain its exclusive property, notwithstanding the fact that its
trade name(s), trademark(s), logo(s) and icon(s) have been included in a work
product prepared by the other party.  Each party hereby grants to the other
until the effective date of termination of this Agreement a limited,
nontransferable, and nonexclusive license to use its work product in the
Territory solely as necessary to perform such party's obligations hereunder.

9.  CONFIDENTIALITY

9.1  Nondisclosure and Nonuse Obligations. Each party shall not disclose to
     ------------------------------------
third parties all information and know-how in any form, transmitted to the other
that the disclosing party has identified, by letter or other written notice, as
being proprietary or confidential ("Confidential Information"), and shall make
no use of such information and know-how except under the terms and during the
term of this Agreement.  Each party shall treat as Confidential Information of
the other party information regarding the other party's pricing, marketing and
sales strategies, and internal operations procedures as proprietary and
confidential, regardless of whether such information has been identified
proprietary or confidential at the time of disclosure.  Neither party shall have
an obligation pursuant to the foregoing to protect that portion of such
information that (i) it rightfully received from another party, without
restriction on use or disclosure prior to its receipt from the disclosing party;
(ii) the disclosing party has disclosed to a third party without any
restrictions on use or disclosure; (iii) enters the public domain (i.e.

                                                                              11

without any restrictions on use or disclosure) by some action other than breach
of this Agreement by the receiving party; (iv) is independently developed by or
for the receiving party; or (v) is disclosed pursuant to a valid subpoena or
other government order. Each party shall safeguard proprietary or confidential
information disclosed by the other using the same degree of care it uses to
safeguard its own proprietary and confidential information but, in no event,
shall use less than a reasonable degree of care. Each party's obligation under
this paragraph shall extend for a period of three (3) years following
termination or expiration of this Agreement.

9.2   End User Information.  The parties agree to treat End User information, to
      --------------------
include proposals, pricing and type of services provided, as Confidential
Information under the terms of the preceding subsection.  In addition, the
parties agree that, as between them, the End User information of a customer that
is identified and brought into the Genuity - Bell Atlantic relationship as a
customer or potential customer, shall be the Confidential Information of the
party that identified and brought the End User to the relationship. If the
parties assist each other in the marketing of the Genuity Services, the End User
information related to that marketing shall be the confidential information of
the party that has the primary relationship with the End User.  A party that
receives End User information of the other party shall restrict its use of that
information solely to the transactions relating to the Genuity Services, and
shall not disclose any such End User information to other parts of the party's
organization, to include any other sales channel.

10.  INDEMNIFICATION.

10.1  Infringement. Genuity shall defend and indemnify Bell Atlantic and hold
      ------------
Bell Atlantic harmless from any damages, costs and attorneys fees finally
awarded against Bell Atlantic and its End Users based upon a claim that Genuity
Services infringe any U.S. patent, copyright, trademark, trade secret or other
intellectual property right provided that Bell Atlantic promptly notifies
Genuity in writing of such claim and cooperates with Genuity by providing
Genuity with the opportunity, full authority, and assistance (at Genuity's
expense) to defend or settle the claim.  Should any Genuity Service become, or
likely to become, in Genuity's opinion, the subject of a claim, Genuity may at
its option and expense: (i) replace or modify the Services so that that
infringement does not exist; (ii) procure for Bell Atlantic and its End Users
the right to continue to use the infringing Genuity Services; or, if (i) and
(ii) are not commercially reasonable, (iii) cease providing the infringing
Genuity Services and refund to Bell Atlantic any payments made for the
terminated Genuity Service for the period after the termination date.  This
section states the entire liability of Genuity with respect to infringement of
any intellectual property rights by Genuity and its suppliers and Genuity and
its suppliers shall have no additional liability with respect to any alleged or
proven infringement. Genuity shall have no liability for and Bell Atlantic shall
indemnify and hold Genuity and its suppliers harmless from any and all claims,
damages, costs and attorneys fees Genuity incurs from any claim arising solely
from (a) the combination, by Bell Atlantic or its End Users, of Genuity Services
with other products or services not provided by Genuity that are not authorized
by Genuity  or are not reasonably intended to be used in combination with the
Genuity Services, or (b) any alteration or modification of Genuity Services that
were not made or authorized by Genuity or (c) the use of a Genuity Service by
either Bell Atlantic or its End Users in a manner for which it was neither
intended or designed.   The parties disclaim the implied warranty of non-
infringement, relying instead on the terms of this Section.

10.2  General Indemnity.  Genuity and Bell Atlantic shall each indemnify, defend
      -----------------
and hold the other party and its affiliates, and their respective agents,
representatives, employees, directors, officers and assigns harmless against any
losses, damages, liabilities, claims or demands (including all costs, expenses
and attorneys' fees on account thereof or in connection with any investigation
or preparation related thereto or the enforcement of the indemnification
provisions of this Agreement) that may be made as a result of claims made: (i)
by anyone for bodily injuries (including death) to persons or damage to or theft
of tangible or

                                                                              12

intangible property resulting from the indemnifying party's or its agents'
intentional and willful misconduct or negligent acts or omissions or those of
persons furnished by such party while performing work hereunder pursuant to this
Agreement or in connection with materials furnished by such party pursuant to
this Agreement excluding any claims based on lost data or information unless
such claims are based on intentional and willful misconduct; (ii) by persons
furnished by the indemnifying party or any contractors based on employment
contract, or federal, state or local laws prohibiting discrimination in
employment; (iii) by persons furnished by the indemnifying party or any
contractors under worker's compensation or similar acts; or (iv) resulting from
or in connection with the indemnifying party's or its agents' breach of any
applicable law, statute, order, decree, or regulation in performance of its
obligations hereunder. In addition, Bell Atlantic shall indemnify, defend and
hold harmless Genuity and its affiliates, and their respective agents,
representatives, employees, directors officers and assigns harmless against any
losses, damages, liabilities, claims or demands (including all costs, expenses
and attorneys' fees on account thereof or in connection with any investigation
or preparation related thereto or the enforcement of this indemnification
provision) that may be made by any third party for claims arising from Bell
Atlantic or Bell Atlantic's End Users' use of the Genuity Services and that are
not (i) otherwise subject to indemnification under this Agreement or a Service
Schedule, or (ii) proximately caused by the negligent acts or omissions or other
willful misconduct of Genuity or its affiliates, or their respective agents,
representatives, employees, directors officers or assigns. The indemnified party
shall provide written notice to the other party of any written claims or demands
against it for which the other party is responsible hereunder and shall be
entitled, at its option, to assume the defense or settlement of any such claim.

as stated in Section 11.3, the service level guarantee remedy shall be in

14.2 Entire Agreement. This Agreement constitutes the entire agreement between
     ----------------
the parties with respect to the subject matter hereof and supersedes all prior
and contemporaneous communications, representations and agreements. The recitals
in this Agreement are illustrative only and shall not be binding on the parties.
This Agreement shall not be modified except by a written agreement dated
subsequent to the date this Agreement is executed by both parties, and signed on
behalf of the Bell Atlantic and Genuity by their respective duly authorized
agent. The provision of any Genuity Service to Bell Atlantic that was, prior to
the Effective Date of this Agreement, provided under another agreement, shall be
provided pursuant to this Agreement after the Effective Date. If the prices,
terms or conditions applicable to such Genuity Service are more favorable to the
End User under the prior agreement, the more favorable prices, terms or
conditions shall apply for that End User.

14.3 Severability. If any provision of this Agreement is declared or found to
     ------------
be illegal, unenforceable or void, then it shall be amended to the extent
necessary to make it legal and enforceable while preserving its intent; the
unenforceability of any provision of this Agreement shall not impair the
enforceability of any other provision of this Agreement.

14.4 No Waiver. No waiver of any breach of any provisions of this Agreement
     ---------
shall constitute a waiver of any prior, concurrent or subsequent breach of the
same or any other provisions hereof, and no waiver shall be effective unless

14.5 Nonassignability and Binding Effect. (i) Neither party shall assign any
     -----------------------------------
right or interest under this Agreement, except for monies due or to become due,
nor delegate any work or other obligation to be performed or owed under this
Agreement to any third party without the prior written consent of the other
party, provided, however, that the merger or consolidation of one party into, or
the sale of all or substantially all of the assets of such party to, a third
party shall not be deemed to be an assignment. Any attempted assignment or
delegation in contravention of the above shall be void and ineffective.  Subject
to the foregoing, this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their permitted successors and assigns.
Notwithstanding the above, each party shall have the right to assign this
agreement and to assign its rights and delegate its duties under this agreement,
either in whole or in part (an "assignment"), at any time and without the other
party's consent, to any wholly-owned subsidiary or affiliate of the assignor.
The assignor shall give the non-assigning party written notice of any
assignment.  The assignment shall neither affect nor diminish any rights or
duties that either party may then or thereafter have as to Genuity Services
ordered by Bell Atlantic prior to the effective date of the assignment.  (ii)
Any assignment of monies by the assignor shall be void and ineffective to the
extent that (i) the assignor has not given the non-assigning party at least
sixty (60) days prior written notice of such assignment and (ii) such assignment
attempts to impose upon the non-assigning party obligations to the assignee
additional to payments of such monies or to preclude the non-assigning party
from dealing solely with the other party in all matters pertaining to the
Agreement.

14.6 Force Majeure. Neither party shall be in default of any obligation under
     -------------
this Agreement or any Service Schedule nor liable for any delay or failure in
performance which results directly or indirectly from Acts of God, casualty,
acts of civil or military authorities, civil disturbances, war, strikes or other
labor-related disputes, fires, disruption in transportation, flood, lock out,
epidemic, destruction or shut-down of facilities, railroad disaster, cable cut,
shortage or curtailment, or other causes beyond the party's reasonable control.

     ---------------------
statute, order, rule, or regulation or any state or federal regulatory agency
having competent jurisdiction over one or both of the parties hereto or the
services provided hereby.  The parties agree to cooperate with each other and
with any applicable regulatory agency so that any and all

                                                                              15
<PAGE>

necessary approvals may be obtained. During the term of this Agreement, the
parties agree to continue to cooperate with each other in any review of this

Agreement or any Service Schedule hereunder, Bell Atlantic's obligation to pay
for Genuity Services provided hereunder shall continue.  Any obligations,
duties, or rights that may, by their nature, extend beyond the expiration or
termination of this Agreement or any particular Service Schedule, shall survive
any such expiration or termination.  Nothing in this section shall affect either
party's rights or remedies at law or in equity in the event of a breach by the
other party.

14.9   Governing Law. This Agreement shall be governed by the laws of the
       -------------
Commonwealth of Massachusetts without regard to its conflicts of laws
principles.

14.10. Compliance with Laws.  The parties shall comply with all applicable
       --------------------
laws, statutes, ordinances, directives, rules, regulations, orders and decrees
of any court or regulatory authority of competent jurisdiction in performing
this Agreement. If Bell Atlantic requires Genuity to temporarily adjust its
business as set forth in this Paragraph, Bell Atlantic shall provide Genuity
with 180 days prior written notice of the date on which Bell Atlantic intends to
exercise its option to convert its B Shares of Genuity stock ("Bell Atlantic
Notice"). In the Bell Atlantic Notice, Bell Atlantic may, at its discretion,
designate certain States in which it does not expect to have legal authority
under applicable federal law ("Bell Atlantic Designated States"), to operate
Genuity at the time of the Bell Atlantic conversion. Upon receipt of the Bell
Atlantic Notice, Genuity shall temporarily adjust its business in the Bell
Atlantic Designated States in such a manner, as Genuity determines in its sole
discretion, as will allow Genuity to operate in compliance with applicable
federal law in such States on or before the conversion date set forth in the
Bell Atlantic Notice. In no event shall (1) the Bell Atlantic Designated States
account for greater than 3 percent of Genuity's total revenue, as measured by
comparing the revenue arising out of Genuity business in the Bell Atlantic
Designated States to Genuity's revenue for its overall operations for the prior
12 months before the date of the Bell Atlantic Notice and/or (2) the
adjustment of Genuity's operations result in the loss to Genuity of overall
revenue of more than 3% of its revenue for the prior 12 months before the date
of the Bell Atlantic notice. Bell Atlantic agrees to pay an amount necessary to
make Genuity financially whole as a result of Genuity's modifications to its
business under this Paragraph. Such amount shall not be greater than 3 percent
of Genuity's total revenue, as described above.

(a)  The parties agree to seek resolution of any claim or dispute arising out of
or related to this Agreement through negotiations as set out in this section

shall first attempt in good faith to reach resolution through discussions at the
non-executive level.  If such efforts are not successful, the parties shall
escalate the dispute to the vice president level in their respective
organizations.  Either party may then submit a written notice to the other party
in accordance with the notice provisions of this Agreement, requesting
initiation of these dispute resolution procedures.  The notice shall set out the
nature of the dispute and shall identify the person in the notifying party's
organization who has the authority to reach final decision on the dispute.
Within ten (10) days of receipt of such notice, the receiving party shall
respond in writing with designation of the person in its organization who has
the authority to reach final decision on the dispute.  The representatives shall
then meet and negotiate in good faith to resolve the dispute.  The discussions
shall be left to the discretion of the representatives, who may utilize other
alternative dispute resolution procedures such as mediation to assist in the
negotiations.  Discussions and correspondence among the representatives for
purposes of these negotiations shall be treated as confidential information
developed for purposes of settlement, shall be exempt from discovery and
production, and shall not be admissible in any lawsuit or administrative
proceeding without the concurrence of all parties pursuant to Rule 408 of the
Federal Rules of Evidence.  Documents identified in or provided with such
communications, which are not prepared for purposes of the negotiations, are not
so exempted and may, if otherwise admissible, be admitted in evidence in the
arbitration or lawsuit.  The parties agree to pursue resolution under this
subsection for a minimum of 60 days following the first written notice
requesting initiation of these dispute resolution procedures before pursing
arbitration as set forth in subsection (b), below.  The foregoing procedure
shall not apply to claims or disputes relating to confidential information,
other intellectual property, or indemnity rights or obligations.

(b)  If the parties cannot resolve the dispute in accordance with subsection
(a), above, either party shall have the right to cause the parties to enter into
binding arbitration in accordance with the rules of the American Arbitration
Association then in effect. The place of arbitration shall be conducted in the

arbitrators, for such arbitration. Any award rendered therein shall specify the
findings of fact of the arbitrators and the reasons for such award, with

for their own costs in the arbitration and shall share equally in the cost of
the arbitrator and any related costs such as meeting space and the like.

extent such failure is not proximately caused by negligent or otherwise wrongful
acts or omissions of Genuity or any Genuity agent or by Genuity's breach of the

(vi)      Upon request, Genuity will order the LEC/CAP circuit for Bell
     Atlantic's customer on behalf of Bell Atlantic. Genuity will use
     commercially reasonable efforts to obtain discounts commensurate with
     volume from underlying access circuit providers. Where such charges are
     priced as "pass-through", Genuity will pass through actual charges without
     mark-up.

     complex and require technical expertise and broad product and service
     knowledge. In the event Genuity receives the trouble report from Bell
     Atlantic's End User, or from Genuity's internal electronic monitoring
     systems, Genuity shall agree to notify Bell Atlantic via phone and/or
     E-mail with all pertinent information. Both Parties will mutually agree

report of total orders placed, number of expedites requested, number granted

                                                                               3

updates to the available Services that entail an amendment or expansion of the
existing Service Description for that Service, but do not constitute a New
Release.  In the event there are any impacts to pricing, order entrance

notice impractical, Genuity will provide such lesser notice as is practicable.

and conditions for the new services. Bell Atlantic, in its sole discretion,
shall select the calendar date on which Bell Atlantic shall elect to roll out
new Genuity Services. Bell Atlantic shall provide Genuity forty-five (45) days

other networks or other Genuity customers.Genuity reserves the right to prohibit
incidences of unacceptable use of e-mail (as defined in this section) by
restricting all outbound IP data packets using port 25 to a single IP address

or liability for the actions of local jurisdictions, which may restrict or block
the Services.

established in this Service Schedule.

----------
SitePatrol, and Security Advantage Services (and bundles containing such
services as a component):

     ------------------------
encryption technology internationally may be subject to restrictions.  Genuity
will endeavor to obtain the necessary approvals for each international site
ordered.  Bell Atlantic agrees to cooperate with Genuity as may be reasonably
necessary to satisfy the required approvals.  In some cases, approval may
require the passing of title of certain customer premises equipment to the End
User.  Bell Atlantic agrees to secure the reasonable cooperation of End User to
assist in obtaining the requisite approvals.  Genuity's acceptance of an order
for Service, and Genuity's  obligation to provide Service, in any

                                                                               8
<PAGE>

given non-U.S. location is expressly conditioned on Genuity's ability to obtain
the regulatory, legal, vendor, and import and export approvals (including those
required for encryption technology) as Genuity deems necessary and under such
terms and conditions as Genuity deems adequate, in Genuity's sole discretion. In
the event that Genuity is unable to obtain such approvals for a given location,
Genuity may decline to accept or void the order quotation for Services at that
location without penalty or obligation. For applicable international Services,
this section shall supercede any acceptance criteria stated elsewhere in the

4.   Security Policy.  End Users remain responsible for their network security
     ---------------
policy and security violation response procedures. VPN Service enhances End
Users' ability to create and secure a virtual private network and impede
unauthorized access to the End User's network and data transmitted using the VPN
service. Bell Atlantic acknowledges that VPN Service does not by itself
guarantee network security or prevent security incidents, that neither Genuity
nor its suppliers is responsible for unauthorized access to the End User's
facilities or for damages arising out of unauthorized access, and that it is the
End User's responsibility to design a comprehensive security program in
conjunction with any other service providers or professionals chosen by End
User.

5.   Restrictions on system access.  Genuity configures and remotely manages the
     -----------------------------
software for all systems Genuity installs on an end user's premises in
conjunction with VPN service (e.g., The VPN gateway device). Bell Atlantic shall
include terms in its agreements with end users which allow Genuity (or
designated representative) to access End Users' premises for the purpose of
installing and maintaining such equipment. End User may access the configuration
of such systems only when authorized by Genuity; therefore, neither Bell
Atlantic nor end user will need or receive a software license. Bell Atlantic
agrees to abide by, and ensure that end users abide by, the license terms to the
VPN client software. Bell Atlantic agrees not to, nor permit End Users to,
remove, obliterate or cover any marks, logos, or notices included with the
equipment Genuity installs on End Users' premises.

6.   Return of Equipment and Software.  Upon termination or expiration of the
     --------------------------------
Service Period applicable to any End User (unless extended by the parties), Bell
Atlantic agrees to return or cause End User to either return  to Genuity or
dispose of all hardware and software which Genuity has provided to in connection
with the VPN Service in accordance with the following:

     6. 1.  Genuity-Owned Equipment and Software.  Bell Atlantic agrees to
            ------------------------------------
     return to Genuity all Genuity-owned hardware and software which Genuity has
     provided to Bell Atlantic and/or End User in connection with the VPN
     Service. If such hardware and software are not returned to Genuity within
     sixty (60) days following such termination or expiration, Bell Atlantic and
     End User will permit Genuity to remove such hardware and software from End
     User's premises upon reasonable notice during normal business hours, at
     Bell Atlantic's or End Users cost and expense. Bell Atlantic will also be
     responsible for all applicable late return fees, as stated in the Service
     Description.

     6.2    Genuity-Provided Equipment.  In certain cases, Genuity may pass
            --------------------------
     title of equipment to End User for a given site, as specified in the
     service order (or otherwise agreed to in writing between the parties). In
     the event that title to equipment is passed to End User, then, at the end
     of the applicable service period, End Users shall agree to either: (a)
     transfer title to the equipment to Genuity or a designated agent in
     exchange for its remaining salvage value; or (b) to destroy the equipment,
     and certify such destruction, in accordance with U.S. and local laws.

     6.3    Genuity-Provided Software.  Regardless of the origin or ownership of
            -------------------------
     the hardware End Users shall agree that, at the end of the applicable
     Service Period End User shall, at Genuity's option, either: (a) certify
     that End User has returned and/or destroyed any software which Genuity has
     provided to End User (or End User's foreign affiliate) in connection with
     the VPN Service including media containing copies thereof (e.g. CD ROM); or
     (b) permit Genuity to remove and/or delete such software, copies and media.

7.   Export Restrictions. The customer premises equipment and software (e.g. the
     -------------------
VPN Gateway Device) installed on the customer premises are authorized by the
U.S. government (and other applicable regulatory authorities) for export only

                                                                               9
<PAGE>

to the country/location authorized in the applicable Service Order or otherwise
authorized in writing by Genuity.  They may not be resold, diverted,
transferred, transshipped, or otherwise be disposed of in any other country,
either in their original form or after being incorporated through an
intermediate process into other end items, without the prior written approval of
the U.S. Department of Commerce and Genuity.  Bell Atlantic acknowledges that
the VPN client software contains encryption technology subject to export
control, and agree to abide by, and ensure that end users abide by, laws and
regulations applicable to import and export of the VPN client software.

8.   Warranties Regarding Third Party Equipment.  In the event that Genuity
     ------------------------------------------
transfers title to equipment to Bell Atlantic or End User, Genuity will endeavor
to pass through such representations and warranties provided by the manufacturer
of any equipment purchased from Genuity hereunder.  Bell Atlantic understands
and agrees that the sole and exclusive recourse for any claims or damages
relating to the third party equipment shall be to the manufacturer of such
equipment, and not to Genuity.  Except as expressly provided elsewhere in the
Agreement, Genuity is providing the equipment AS IS, AND GENUITY DISCLAIMS ALL
WARRANTIES OR REPRESENTATIONS, BOTH EXPRESS AND IMPLIED, INCLUDING BUT NOT
LIMITED TO THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  UNDER NO CIRCUMSTANCES SHALL GENUITY BE LIABLE FOR ANY DAMAGES THAT
MAY RESULT FROM THE USE OF OR INABILITY TO USE THE EQUIPMENT.

---------
DiaLinx VISP Services (and bundles containing such services as a component):

1.   End User Responsibility:  Bell Atlantic agrees to be responsible for all
     -----------------------
billing and collection from  individual users and that Bell Atlantic will pay
Genuity on a timely basis, regardless of whether Bell Atlantic collects payment
fromusers.  Bell Atlantic agrees to be responsible for all communications to and
business relations withusers.  Unless Bell Atlantic has purchased optional help

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.  Bell Atlantic is
responsible for authenticating and authorizing access by Bell Atlantic's users
to the DiaLinx Service.  Unless Bell Atlantic has purchased optional RADIUS
hosting services from Genuity, Bell Atlantic shall install, operate, and
maintain a dedicated RADIUS server meeting the RADIUS specifications published
in Internet RFC 2138 and 2139 and all published derivative RFC's.  Genuity's
RADIUS server will prompt each end user for the end user's identification and
password, and poll Bell Atlantic's RADIUS server for access information.  Unless
otherwise additional realms are purchased, Genuity will support up to a maximum
of five (5) authentication realms (e.g. companyname.com) per End User.

2.   Service Cancellation: Bell Atlantic may cancel a Service connection at any
     --------------------
time by providing 60 days prior written notice via email to the designated
cancellation point of contact.

3.   Equipment and Telephone Service.  Bell Atlantic is solely responsible for
     -------------------------------
obtaining and providing the telephone services and user modems necessary to
access DiaLinx Service.  In no event will Genuity be responsible for end user
telephone charges.

4.   Network Access Availability.  ACCESS TO THE DIALINX NETWORK CANNOT BE
     ---------------------------
GUARANTEED TO BELL ATLANTIC OR BELL ATLANTIC'S END USERS.  END USERS MAY BE
UNABLE TO ACCESS THE DIALINX SERVICE AT ANY GIVEN TIME, AND DISCONNECTIONS MAY
OCCUR FROM TIME TO TIME.  BELL ATLANTIC AGREES THAT GENUITY WILL NOT BE LIABLE
FOR ANY DAMAGES THAT BELL ATLANTIC OR BELL ATLANTIC'S END USERS MAY 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 AGREEMENT.

                                                                              10

5.   Regulatory Changes.  Genuity shall flow through to Bell Atlantic any local
     ------------------
exchange carrier (LEC) price changes (a) that are attributable to changes in
Federal or state regulation, or (b) 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.

6.   Local Access Numbers. Genuity expects the DiaLinx network to change over
     --------------------
time in order to meet the needs of customers. Genuity reserves the right to add
to, delete or change the dial-in access numbers associated with a specified
service category from time to time. Bell Atlantic will be notified of changes to
the DiaLinx network or access numbers via periodic e-mail updates. Genuity 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 on-going basis, via e-mail updates notifying Bell Atlantic of
the additional service. Use of such additional services by Bell Atlantic or Bell
Atlantic end users will be deemed Bell Atlantic's 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 Genuity's Web page as
listed in the DiaLinx Service Description.

Notes:

(1)  Pricing excludes administration of customers' user authentication or
     accounting databases, VPN configuration on the firewall, and configuration,
     management, and administration of customer De-Militarized Zones (DMZ) which
     will be quoted on a Time and Materials (T&M) basis for each individual
     customer opportunity. These additional charges are not eligible for
     Multi-Service Discounts.

(2)  Installation Fee for Security Advantage is not eligible for Multi-Service
     Discounts.

(3)  The pricing set forth above for Security Advantage shall be effective upon
     execution of the Agreement. GTEI and NEWCO shall review Security Advantage
     pricing on a quarterly basis. At each quarterly review GTEI shall notify
     NEWCO (1) if it has experienced reductions in the operating costs
     applicable to the Security Advantage product or (2) if it has offered
     pricing to other purchasers of the Security Advantage product which is
     below the then current NEWCO pricing. In the event GTEI has experienced
     such cost reductions, GTEI shall reduce the NEWCO pricing for the Security
     Advantage product accordingly, to the extent such cost reductions are
     commercially practicable. In the event GTEI has offered other purchasers
     more advantageous pricing, GTEI shall reduce the NEWCO pricing for the
     Security Advantage product to be at least as beneficial as such pricing.
     This pricing schedule shall be amended to reflect any such pricing
     reduction.

                               VOLUME DISCOUNTS

-------------------------------------------------------------
        Actual Monthly Revenue                  Additional

Exclusions:
-----------

The Volume Discount shall apply to all standard MCS Services with the exception
of the following MCS service components which are excluded:

Notes:
------
A "standard service quotation" for purposes of this Attachment is one in which
all the MCS services and products purchased by Bell Atlantic or Bell Atlantic's
customer are found in the applicable MCS Service Description at the time the
quotation is generated.

Price lock-in per ordered connection:  Each new connection will be priced at the
-------------------------------------
baseline price in effect at the time the connection is originally ordered for at
least 12 months following its installation. Each renewed connection will be
priced at the baseline price in effect at the time the connection is renewed for
at least 12 months following its renewal. That means that when baseline pricing
changes, the new prices only apply to new orders and some subset of renewals. In
particular, in the case of renewals, new pricing will not be applicable unless
the connection's previous price had been in effect for at least 12 months.

     duration of the Service Period to use such software in object code form
     only, on the hardware upon which it is installed, for the sole purpose of
     enabling you to use Enterprise Advantage Services.  You agree to accept any
     additional license terms required by the suppliers of such software as
     indicated in the Service Description.  You acknowledge and agree that title
     to all such software remains with the Services Supplier and its vendors, if
     any, that the content and design of such software are valuable trade
     secrets, and that you may use such software for the sole purpose of
     enabling you to use Enterprise Advantage Services.  You agree not to (a)
     disclose or make available to third parties any portion of such software
     without the advance written permission of the Services Supplier; (b) copy
     or duplicate such software; (c) reverse engineer, decompile or disassemble
     such software; or (d) modify or make derivative works of such software.
     You agree not to use such software after the Service Period without

     party software vendor.  You also agree to accept any additional license
     terms required by the Services Supplier's vendors for the Enterprise
     Advantage options you have chosen.  All such license terms are set forth in
     the Service Description.

     If you purchase a software option in which you are responsible for
     acquiring the license and the Services Supplier agrees to install the
     third-party software for you, you are solely responsible for obtaining a
     valid license from the software vendor.  If the Services Supplier purchases
     any third-party software on your behalf, you agree to sign any required
     third-party license agreements prior to delivery or installation of the
     third-party software.  If Service Supplier installs third-party software at

     Dedicated Internet Access Network Service Level Agreements (SLAs) Violation
     and Remedies.

Genuity's failure to meet the following Network SLAs will result in a percentage
credit on the Bell Atlantic's bill for the following month for the affected
network. The SLA credit percentage is dependent on the number of consecutive
months of SLA failure and the degree of failure. Terms and metrics not otherwise
defined below will have the meaning set forth in the standard dedicated access
SLAs.

Note: Network Availability and Latency SLAs are mutually exclusive - for
example, a large latency timeframe would indicate a Network Outage.  A
percentage of the affected Bell Atlantic customers' total recurring monthly fee
will be remitted back to Bell Atlantic as indicated in the tables below.

Bell Atlantic will require access to Genuity's Stats Advantage system to be able
to verify Network Outage and Latency for Bell Atlantic customers.

** Remedy is a percentage credit to Bell Atlantic for the specific customer's
MRC for the next bill in Bell Atlantic's billing cycle.

*** Customers will also receive full credit of the NRC/Installation for
BizConnect if total installation takes * days or more.

If Genuity is not able to meet such requested provisioning date, Bell Atlantic
may, within five (5) business days, cancel Bell Atlantic order without incurring
cancellation charges. If Genuity is not able to deliver the services within *(*)
calendar days, Bell Atlantic has the right to terminate the service order
without penalty.

Delays caused by customer provided CPE shall not be factored into the SLA
compliance for any of the above-referenced SLAs. Orders shall be considered
"complete and accurate" if they meet the requirements specified by the PMO from
time to time.

Within * business days from the time Genuity receives a     25% off the standard installation fees for the Quotation
quotation request package from Bell Atlantic, Genuity       (provided Genuity wins the business)
shall either:

(i) issue a quote if the quotation request package for
standard EA services is complete and accurate; or

(ii) reject the quotation request package if it is
incomplete and/or inaccurate.  Genuity will also give
Bell Atlantic reasons for the rejection in a manner to
be mutually agreed upon in accordance with the
procedures under Section 3.2 of the Agreement.

A complete and accurate quotation request package
consists of a completed configuration template, a visio

which have been approved by Genuity.

Note: If Genuity determines that the quotation process for Bell Atlantic is
unduly burdensome, Genuity can suspend the Enterprise Advantage Quoting SLA at
its discretion for 30 days while a new agreement is reached.

</TABLE>

     Genuity will make an Enterprise Advantage provisioning SLA available to
     Bell Atlantic (i) within 6 months of signing this Agreement, or (ii) when
     Genuity makes a provisioning SLA generally available to its web hosting
     customers, whichever is earlier.

     At the present time, Genuity anticipates that the EA provisioning SLA that
     will be provided to Bell Atlantic will be along the following lines:

          For all EA Service Quotations, Genuity will meet the delivery date
          given to Bell Atlantic upon completion of a successful kickoff
          meeting, including receipt by Genuity of a complete and accurate order
          package which has been approved by Genuity, for the EA Service
          Quotation. In the event that Bell Atlantic or Bell Atlantic's End User
          Customer has caused any delays that materially impact the provisioning
          process, the delivery date given by Genuity shall be void and this SLA
          shall not apply.

          Remedy if Genuity fails to meet the SLA:

          25% off the standard installation fees for the Quotation

     The actual EA Provisioning SLA will be mutually agreed-upon by the parties.

Expedited or accelerated orders are excluded.

/2/ If one of the service elements is dependent on another service element that
has a longer provisioning element, (e.g., Internet Advantage, etc.) then the
longer provisioning interval is utilized. In some cases the intervals may be
additive if the provisioning one service is based on the completed provisioning
of another service. No more than 2 SLAscan be enacted per Bell Atlantic
customer.

/3/ Licensed countries refers to those countries where Genuity has secured an
import and/or operating license (where required) to deliver VPN service. Genuity
will provide post an updated list of Licensed Countries to the Genuity Kbank for
Bell Atlantic reference.

Provisioning timeframe does not start until all required network diagrams and
architectures (collectively "artwork") have been received by Genuity
Provisioning.  All applications are subject to a mandatory architecture review
prior to order acceptance.

If the customer is non-responsive after 3 consecutive phone calls from VPN
Provisioning, Bell Atlantic will be notified and the order will be placed on
hold and excluded from current or future provisioning SLAs for the affected
site(s).

Orders for international service will require customer cooperation in order to
complete export and import documentation for equipment delivery. If customer is
non-responsive after 3 consecutive calls from Genuity, Bell Atlantic will be
notified and the order will be placed on hold and excluded from current or
future provisioning SLAs for the affected sites.

the Projected Delivery Date.  Notwithstanding the immediately preceding
sentence, in the event Bell Atlantic notifies Genuity of any untimely
installation or non-operation of Bell Atlantic's or its End User's facilities,
equipment, or Services at least thirty (30) days prior to the Projected Delivery

disconnected due to security concerns provided that nothing in this Section
shall impact Genuity's rights under Section 21 of this Service Schedule.

plan that incorporates Bell Atlantic's training requirements.  This training
plan will include, but not be limited to quarterly product capability training,
process and systems training with any system and process changes, participation

provide semi-annual technology seminars.  These training sessions and technology
seminars will be limited to Bell Atlantic headquarters employees, including
Marketing, Product Management, Operations, Engineering and Alliance Management.
Genuity will not provide training or technology seminars to Bell Atlantic's End
Users or Bell Atlantic's sales channels.

11. Access Support Services.  At Bell Atlantic's request, Genuity will order
    ------------------------
the LEC/CAP/ALT/IXC Access circuit for Bell Atlantic's End User on behalf of
Bell Atlantic, to  facilitate and coordinate the interconnection between the
Bell Atlantic End User demarcation and Genuity point-of-presence.  Genuity will
act in this capacity only when requested to do so by Bell Atlantic.  Under such
circumstances, Bell Atlantic agrees to execute or obtain from its End User a
Letter of Authorization in a form acceptable to the underlying carrier.  Genuity
shall provide firm fixed pricing for the Access circuits except where subject to
the underlying carriers' applicable tariffs.  Within a period of six (6) months
from the Effective Date of the Agreement, Genuity shall use commercially
reasonable efforts to obtain competitive pricing from the Genuity approved
Access providers (as specified in the Service Availability Report) for Access
charges

                                       4
<PAGE>

that shall be competitive with the prices from such Access providers to
Tier 1 carriers, including AT&T, Sprint, and MCI WorldCom to the extent that
Genuity aggregate volumes generate buying power is equivalent to the referenced
carriers.  If, upon the expiration of the six (6) month period, Genuity have not
obtained such competitive pricing, the Parties will jointly retain a mutually
agreed upon independent third Party no more frequently than a semi-annual basis,
to obtain and provide benchmarking information for similar Access.  The
independent third party will utilize the following criteria for conducting the
benchmarking review: purchasers of Access  who are similarly situated to Genuity
by comparable geographic reach and comparable volumes, and who deliver SLAs
comparable to those specified in the Service Schedule.  Genuity shall have
ninety (90) days after receipt of benchmarking information to meet the pricing
contained therein.  If Genuity fails to meet this pricing, then Bell Atlantic
shall be entitled to relief pursuant to Section 7.3 and Attachment 1 of the
Agreement.  The Parties shall review progress Genuity has made in completing
this process and upon mutual agreement, may extend the six (6) month period.
Genuity will provide Bell Atlantic Access pricing at Genuity's cost with no mark
up, using Genuity's special Access arrangements or tarriffs of the underlying
carrier(s), whichever is less and conforms with the requirements under this
Service Schedule.

The Parties acknowledge that it is their intention that Bell Atlantic should
enjoy network availability from LEC/CAP/ALT/IXC providers equivalent to the
Service SLAs detailed in Attachment A.  Genuity shall make commercially
reasonable efforts to procure such network availability SLA from LEC/CAP/ALT/IXC
providers.  In the event that Genuity is able to obtain from a LEC/CAP/ALT/IXC
provider a credit in the event that a given level of network availability is not
met, and Genuity's SLA remedies for network availability are not invoked, then
such credit shall be prorated to Bell Atlantic on the basis of actual Services
ordered by Bell Atlantic for such underlying carrier(s).  Genuity shall provide
to Bell Atlantic and keep updated a list of LEC/CAP/ALT/IXC providers that
guarantee a minimum level of availability for such services.  However, where a
LEC/CAP/ALT/IXC provider does not guarantee such availability, Genuity shall
have no liability to Bell Atlantic in the event that the LEC/CAP/ALT/IXC
provider fails to meet the availability target.  In such circumstances, Genuity
shall notify Bell Atlantic promptly of the availability that is being offered by
the LEC/CAP/ALT/IXC provider in question.

12. Pre-Sales Support.   In order to facilitate the quote and RFP process to
    -----------------
Bell Atlantic, Genuity will provide the following:

A.  Standard Quote Process Support for Access.  Genuity will provide pricing
quotes for Access as specified in Section 10 within the time required in the
SLAs.  Further details on this quote process, including identification of who
will submit and who will receive such quotes, will be mutually developed between
the Parties.  Within ninety (90) days after the Effective Date of the Agreement,
Parties shall complete a mutually agreed upon plan to define specifications to
automate/mechanize the quote process.

B.  Facilities Availability Inquiry.  Genuity will conduct facility availability
inquiries for Services within the time required in the SLAs.  Further details on
this inquiry process, including

                                       5
<PAGE>

identification of who will submit and who will receive such inquiries, will be
mutually developed between the Parties.

C.  Custom Bid Support.  Genuity will provide support as mutually agreed and
pricing to Bell Atlantic for bids which have requirements beyond the scope of
Services and functionality in the Service Schedule (a "Custom Bid").  Pricing
for the Custom Bid shall consist of mutually agreed pricing limited to the scope
of Services and functionality proposed in the Custom Bid.  Custom Bids include,
but are not limited to, customized responses relative to network operations or
installation requirements, network configuration, network buildout, significant
numbers of end user sites and/or significant bandwidth opportunities mix of U.S.
domestic and non-U.S. international cross border and/or non-U.S. domestic
venues, support of special billing arrangements and other similar extenuating
circumstances.

     1) Bell Atlantic shall submit to Genuity a Custom Bid Request in a form,
     which will be mutually agreed upon by the Parties within ninety (90) days
     after the Effective Date of the Agreement.  The Custom Bid Request form
     shall contain, at a minimum, the following information: a summary of the
     Custom Bids, technical specifications, and Bell Atlantic required response

     Atlantic management prior to submission to Genuity.
     2) Genuity will respond to Bell Atlantic within two (2) business days from
     the receipt of the request with a representation as to whether Genuity will
     respond to the request and if so, an estimated time of completion for
     responding to such request.
     3) Genuity is not primarily responsible for presentation of the Bell
     Atlantic response but will, at Bell Atlantic's reasonable request, support
     Bell Atlantic's response presentation;
     4) The Parties will enter into an addendum to this Service Schedule to
     cover each Custom Bid and its associated pricing agreed upon by the
     Parties, and the Parties will perform the same in accordance with the
     addendum.
     5) Any information provided by Bell Atlantic to Genuity for the Custom Bid
     shall be treated as confidential information in accordance with Section 9
     of the Agreement.

D.  Expedite Quotes Process.  Upon Bell Atlantic request, Genuity will use
    ------------------------
commercially reasonable efforts to expedite quotes for Customer Bid and Access
to accommodate Bell Atlantic End User requirements.

13. Order Entry and Provisioning.

A.  Order Process and Acceptance/Rejection Notification

To facilitate the ordering and provisioning of Services to Bell Atlantic, the
Parties will use mutually agreed processes for exchange of new, additional,
supplemental, change, pre-install cancellation and/or disconnect service orders.
Bell Atlantic will submit to Genuity Orders for Services in accordance with the
procedures contained in this Section and Attachment D of this Service Schedule.
These procedures may be amended from time to time by mutual agreement of

                                       6
<PAGE>

both Parties. All such changes as agreed to by the Parties shall be made in
writing and incorporated into this Service Schedule. The following will be
applicable to all such Orders:

     Bell Atlantic will send Genuity a complete and accurate Order for each
     Service ("Order") in the form set forth in Attachment E as may be modified
     from time to time by mutual agreement of the Parties, which shall contain,
     among other things, the date that Bell Atlantic requests Service be
     available for use ("Desired Due Date").   To the extent that the Service
     has a standard Installation Interval as described in Attachment A, the
     Desired Due Date shall be no earlier than the standard Installation
     Interval unless the Desired Due Date has been approved pursuant to the
     Installation Interval Expedite process set forth below.

     Within two (2) business days of receipt of the Order, Genuity will notify
     Bell Atlantic that it has either accepted or rejected the Order.  An Order
     may only be rejected if it is materially deficient or materially defective.
     Acceptance of the Order means that Genuity has approved of the form of the
     Order, e.g., the Order is complete, all fields are filled in, and that
     Genuity will commence processing the Order.  Notwithstanding the foregoing,
     if Genuity accepts an Order for End-to End Service on the good faith belief
     that it is complete and accurate, that Order may be subsequently rejected
     if the LEC/CAP/ALT/IXC notifies Genuity that the Order is materially
     defective or materially deficient.  If Genuity rejects the Order, the
     notice of rejection will provide an explanation for such rejection, e.g.,
     the Order lacks sufficient information and specific details of such
     deficiency.  Resubmission of a rejected Order constitutes the submission of
     a new Order for the purpose of Order processing.

     If Genuity has not responded to Bell Atlantic with a status of the Order
     within two (2) business days of Genuity's receipt of the Order, the Order
     shall be deemed accepted by Genuity.

It is mutually recognized that these processes will to some extent be manual as
of the Effective Date of the Agreement, and Genuity shall use commercially
reasonable efforts to expedite the mechanization of these processes.  To that
end, within ninety (90) days of the Effective Date of the Agreement, the Parties
will complete a mutually agreeable Order handling process which will incorporate
the following:

     Genuity will provide to Bell Atlantic in a mutually agreed manner
     mechanized access to the appropriate Genuity system(s) to allow for the
     transmittal of Bell Atlantic Orders to Genuity, the transmittal of Order
     acceptance notification, and rejection/jeopardy notification with detailed
     explanation(s) thereof. Any future Genuity systems development will
     incorporate all mutually agreed upon requirements for Bell Atlantic to
     submit Orders for provisioning at Genuity's expense.

B.  Firm Order Commitment

                                       7
<PAGE>

Genuity shall issue to Bell Atlantic a Firm Order Commitment (FOC) within the
following timeframes: within ten (10) business days of Genuity's acceptance of a
Bell Atlantic Order for PoP-to-PoP Service; within eleven (11) business days of
Genuity's acceptance of a Bell Atlantic Order for DS-3 or lower End-to-End
Service; and within fourteen (14) business days of Genuity's acceptance of a
Bell Atlantic Order for OC-N End-to-End Service.  Genuity will be relieved of
its obligation hereunder in the following circumstances:  a) reasonable outside
construction delays; and b) delays caused by LEC/CAP/ALT/IXC providers.  In the
event that Genuity determines prior to issuance of the FOC that it is unable to
provision an Order, Genuity shall promptly notify Bell Atlantic via email of the
specific reasons for such inability to provision the Order.  The FOC shall
contain the following information: the installation date for the full circuit or
Service as ordered by Bell Atlantic ("Projected Delivery Date"); the Bell
Atlantic circuit ID (as provided to Genuity on the Service Order from Bell
Atlantic); the Genuity circuit ID; and, the circuit ID(s) and delivery date(s)
for all Access and/or interexchange service(s) ordered by Genuity on behalf of
Bell Atlantic in support of the Service Order.  Issuance of the FOC shall
constitute Genuity's agreement to provision the Services in the applicable
Order.  Bell Atlantic and Genuity agree to work cooperatively to meet specific
Bell Atlantic requirements relative to Orders.

C.  Installation Interval Expedites

The Parties mutually agree that they will work together to facilitate requests
for installation intervals shorter than those otherwise agreed as standard on a
case-by-case basis.  The Parties will utilize the Expedite process Attachment F
to the Service Schedule within ninety (90) days of the Effective Date of this
Agreement.  Bell Atlantic shall be entitled to expedite the greater of ten
percent (10%) of all accepted but not installed Orders or five (5) accepted but
not installed Orders at any one time.

D.  Facility Orders via Third Parties

Genuity will issue all applicable Access Service Requests ("ASRs") to the
appropriate LEC/CAP/ALT/IXC.

In the event that Bell Atlantic requests Customer Provided Access (CPA) on one
or more ends of a circuit/Service, Genuity will provide the appropriate Circuit
Facility Assignment (CFA)/Letter of Authorization (LOA) within three (3)
business days of Genuity acceptance of a Bell Atlantic Order.  For purposes of
CPA, Bell Atlantic may only use Genuity approved Access providers for the
specific location as identified in the most current Service Availability Report
described in Section 8(A)(3) of this Service Schedule.

Genuity shall issue to Bell Atlantic a Circuit Layout Report (CLR) within the
following timeframes; ten (10) business prior to the Project Delivery Date for
PoP to PoP Service; and three (3) business days prior to the Projected Delivery
Date for End to End Service.  The CLR shall contain the following information:
Details regarding the layout of the service as ordered and pending delivery;
confirmation of Projected Delivery Date for the full circuit or service as

                                       8
<PAGE>

ordered by Bell Atlantic; the Bell Atlantic circuit ID (as provided to Genuity
on the service order from Bell Atlantic); the Genuity circuit ID; and, the
circuit ID(s) and confirmed delivery date(s) for all local loop or interexchange
service(s) ordered by Genuity in support of the service order.

In the event that Genuity becomes aware of any issue(s) which would have an
impact on the Projected Delivery Date at any point prior to installation,
Genuity shall make Bell Atlantic aware of such issue(s) and work diligently with
Bell Atlantic and with Genuity's own provider(s) to resolve any such issue(s).

14. Change Control Process

The Parties recognize that over the term of the Agreement, Bell Atlantic may
desire to change the scope of the Services as set forth in the Agreement to
account for, among other things, changes in market circumstances, new
technologies and strategic considerations (hereinafter "Service Changes"). The
purpose of this Section is to provide an overall startup process for
accomplishing such Service Changes.

A.  Service Change Request

Right to Make Service Changes.  Genuity shall perform Service Changes requested
by Bell Atlantic in regard to a Service where the terms of the Service Changes
are mutually agreed to by the Parties in advance in writing ("Service Change
Request").  Genuity shall consider any Service Changes requested by Bell
Atlantic unless (i) Genuity considers, at its absolute discretion, that it is
not commercially practical for it to meet the requirements of Bell Atlantic (ii)
the scope of Services after implementation of the requested Service Changes
would differ materially from the purposes and objectives of the applicable
Service or (iii) the Parties have not reached agreement on any associated
adjustment (if any) to Genuity's compensation and/or schedule for the requested
Service Changes.  Where Genuity considers any Bell Atlantic request not
commercially practical, it shall give reasons therefor to Bell Atlantic and
shall work with Bell Atlantic to explore reasonable alternatives.

B.  Service Change Process

1)  Bell Atlantic Request.  The Bell Atlantic Project Manager shall submit
    ---------------------
requests for Service Changes to the Genuity Channel Manager in written form.
The Service Change Request shall contain information concerning the nature of
the requested change (setting forth the business requirements in sufficient
detail for Genuity to respond in a timely and effective manner) as well as a
date by which the Service Change is reasonably required.

2)  Genuity Response.  Within ten (10) business days after receipt of a Service
    ----------------
Change Request, Genuity shall deliver to Bell Atlantic a statement stating its
intention with respect to providing the requested Service Change and
implementation plans where appropriate or practical, as further described below.
In the event that the Genuity responds to Bell Atlantic to the effect that such
requested Service Change cannot be implemented in the time frame desired but
that Genuity

                                       9
<PAGE>

intends to implement such Service Change, Genuity shall set forth the time frame
estimates within which it could implement the Service Change.

3)  Bell Atlantic Approval.  Within a reasonable time following receipt of
    ----------------------
Genuity's Response Bell Atlantic shall provide a written direction to Genuity as
to whether or not it desires Genuity to perform the Service Change. Genuity
shall have no obligation to undertake Service Changes and Bell Atlantic shall
have no responsibility or liability in connection with any Service Changes
undertaken, without specific prior written agreement between the Parties.

C.  Service Change Pricing

The pricing for changing the Service, the pricing for the Service and the terms
and conditions under which the Service shall be provided to Bell Atlantic shall
be mutually agreed upon by the Parties in advance and in writing. Service Change
Pricing shall be consistent with the terms and conditions of this Service
Schedule and the Agreement.  In the event Genuity cannot determine price with
certainty at the time of the initial Genuity Response, Genuity shall use
commercially reasonable efforts to provide a good faith estimate of the pricing
associated with a given Service Change Request, and shall provide firm pricing
to Bell Atlantic as soon thereafter as practicable.

15. Cancellation of Orders/Order Supplements & Change Orders/Disconnection of
    Service

A.  Cancellation of Orders

Order or if Genuity disconnects a Service for Bell Atlantic default, Bell
Atlantic shall pay disconnection charges in the amount of one hundred percent
(100%) of the MRC for the remaining months of the first year and fifty percent
(50%) of the MRC for the balance of the Service Order term.  If Bell Atlantic
disconnects a Service after the first year of the Service Order or if Genuity
disconnects a Service for Bell Atlantic default, Bell Atlantic shall pay a
disconnection charge in the amount of fifty percent (50%) of the MRC for the
balance of the Service Order term.  No such disconnection charges shall apply if
Bell Atlantic terminates the Service pursuant to Sections 6.2 or 6.3 of the
Agreement.

E.  Cancellation/Disconnection Liquidated Damages

It is agreed that Genuity's damages in the event of cancellation/disconnection
may be difficult or impossible to ascertain.  The provision for
cancellation/disconnection charges set forth herein is intended, therefore, to
establish liquidated damages and are not intended as a penalty.

16. Testing and Handover
    --------------------

Genuity shall report the alarm to Bell Atlantic, the potential impact to Bell
Atlantic Services, and log all actions taken to clear the alarm. Genuity shall
perform or facilitate fault localization for the End-to-End Circuit to determine
the resolution. This may involve selecting and scheduling diagnostics or audits.
Genuity will report the results of the fault localization testing to Bell
Atlantic Repair, when Bell Atlantic has opened a specific trouble ticket with
Genuity and/or when Genuity has opened such a trouble ticket with Bell Atlantic.
Genuity shall repair the fault by scheduling, dispatching, and coordinating the
repair forces. This may involve working with other network vendors used to
provide Bell Atlantic service and to provide Bell Atlantic's required service
level objectives.

Genuity shall monitor (24 hours per day, 7 days per week) the Genuity equipment
necessary to provide the Service.  Where Genuity provisions an End to End
circuit or End to Bell Atlantic network interconnect circuit, Genuity shall be
responsible for all trouble testing, isolation, coordination and resolution with
all LEC/CAP/ALT/IXC regarding expected Service restoration for the Genuity
provisioned elements as referenced above.  This responsibility includes opening
trouble reports with any LEC/CAP/ALT/IXC providing local and/or IXC facilities
provisioned by Genuity and performing joint testing with such Parties and Bell
Atlantic.  Bell Atlantic is responsible for coordinating any testing with non-
Genuity contracted Parties.  Genuity shall test Circuits upon installation as
detailed in Section 16 of this Service Schedule and in response to a trouble
ticket.  Within ninety (90) days of the Effective Date of the Agreement, the
Parties will complete a mutually agreeable test plan for repair which shall
include but is not limited to: scheduling parameters, interactive testing,
testing parameter details and the necessary documentation.

Genuity shall administer all trouble tickets referred by Bell Atlantic that
impact Bell Atlantic's purchased Services.  This includes tracking the progress
of the trouble ticket and providing status reports, and keeping a log of the
progress electronically.  Genuity shall contact Bell Atlantic with an
explanation of the trouble resolution and verify that the problem has been
corrected.  Genuity shall perform a mutual ticket closeout process with Bell
Atlantic. Bell Atlantic shall assist Genuity in conducting Service testing when
such is requested by Genuity.  Bell Atlantic shall close out the trouble ticket
with Genuity after Bell Atlantic verifies that the problem reported is resolved.
The trouble reporting process is set forth in Attachment G.  The repair process
flow is set forth in Attachment H.

Genuity shall provide a method for Bell Atlantic to periodically gain
updates/status of Bell Atlantic circuit troubles, using a trouble ticket
reference number or circuit identification. Within ninety (90) days of the
Effective Date of the Agreement, Genuity will also provide Bell Atlantic

                                      13

<PAGE>

I.  Bell Atlantic and Genuity shall cooperate in performing Operational
Readiness Test (ORT) prior to launch of Service(s) in order to test process
flows and network availability. Prior to commencement of testing, Bell Atlantic
shall produce and provide to Genuity an ORT plan that will map out the
anticipated dates for meeting certain milestones in the ORT process, with an ORT
completion date being not later than ninety (90) days from the commencement of
testing. Genuity will produce a matching plan and deliver same to Bell Atlantic
within five business days of Genuity's acceptance of the Bell Atlantic-delivered
ORT plan. In addition, the ORT plan will detail the types of circuits and orders
that will be tested (in terms of speeds, destinations, etc.). The Parties shall
agree on the ORT plan prior to such commencement, and the Parties shall promptly
work together in good faith to resolve any issues raised by either Party and,
upon resolution, testing shall commence as soon thereafter as practicable.

J.  Testing of the operational support procedures shall be conducted at two
levels: (a) a non-physical testing which will ensure that End User orders are
generated properly and handled in an accurate and timely manner, and (b)
physical testing which will require the actual activation of a circuit,
maintenance and monitoring from Genuity over a mutually agreed to specified
period of time.  The ORT plan shall set forth methods for identifying problems
in either the process flows or in network availability, and for escalating all
identified problems within each organization for appropriate and timely
resolution.  For purposes of the actual testing of private line circuits Genuity
shall provide to Bell Atlantic one or more site addresses in Genuity served
regions in order to terminate the physical circuits.  During the ORT testing
period the operations and communications flows within Genuity shall be monitored
and reported to Bell Atlantic as defined and mutually agreed to in the ORT plan,
and any problems identified shall be remedied in an agreed time frame or
escalated for resolution, as necessary.

below) to meet certain network performance criteria.

     -------------------------------------------------------------------------
          Year                    Minimum Number of       Minimum Percentage of
                                  Circuits per Service    Circuits per Service
     -------------------------------------------------------------------------
          1                       10                      20%
     -------------------------------------------------------------------------
          2                       25                      20%
     -------------------------------------------------------------------------
          3 and thereafter        50                      20%
     -------------------------------------------------------------------------

          (a)  The applicable network performance criteria for Private Line
               Service shall consist of the following Private Line Service SLAs,
               which are contained in Attachment A:

               -    Time to Restore Time
               -    Circuit Availability
               -    Auto Restore Time

          (b)  The applicable network performance criteria for ATM Service shall
               consist of the following ATM Service SLAs, which are contained in
               Attachment A:
               -    Average Network Availability
               -    Per PVC Network Availability
               -    Average Cell Loss Ratio
               -    Per PVC Cell Loss Ratio
               -    Peak to Peak Cell Delay Variation

                                      21
<PAGE>

(ii) No more than fifty percent (50%) of the circuits experiencing SLA failure
may originate on a single node or among two (2) Adjacent nodes. For purposes of
this calculation, a node cannot be deemed Adjacent to more than one other node.
In the event of a multiple Adjacency, the node with the highest percentage of
circuits experiencing SLA failure will be the node utilized for purposes of this
calculation (e.g., 3 adjacent nodes will be treated as two (2) nodes for this
calculation; as between those two (2) nodes, the calculation will be made using
the two (2) nodes with the highest percentage of circuits experiencing SLA
failure). For purposes of this section, a "node" shall mean an ADM for Private
Line Service and a switch for ATM Service.

B.   If a Service experiences an Epidemic for two (2) consecutive months, Bell
Atlantic may give written notice to Genuity during such Epidemic that Genuity
has thirty (30) days to cure the Epidemic.  If Genuity does not cure the
Epidemic within thirty (30) days of receiving such written notice, Bell Atlantic
may terminate the affected Service.   Election of this remedy supercedes any
other applicable SLAs for the terminated Service as of the date of election.
Any reduction in the Purchase Commitment shall be governed by the applicable
sections of the Agreement.  To the extent Services are terminated, the Purchase
Commitment reductions shall only apply with respect to services comparable to
the terminated Service under this Service Schedule.  Nothing herein shall limit
either party's right to conduct an audit pursuant to Section 14.12 of the
Agreement.  The Purchase Commitment reduction for termination for a Service
resulting from an Epidemic shall be based upon the most current product-specific
forecast projected to the end of the Term for such Service or twenty percent
(20%) of the balance of the Purchase Commitment at the time of Service
termination, whichever is greater.

29.  Service Level Agreements for Services.  Genuity will meet the Service
     -------------------------------------
Levels specified in Attachment A to this Service Schedule. If Genuity fails to
meet the SLAs, Bell Atlantic shall be entitled to associated remedies specified
in Attachment A and Section 28 above. The SLAs shall not apply in the event of
Force Majeure, Planned Outages or Bell Atlantic and/or Bell Atlantic's End Users
actions that materially impact Genuity's ability to meet the SLAs. The SLA
remedies identified herein shall be Bell Atlantic's sole and exclusive remedy
for SLA failure, except for the following: (i) Genuity's gross negligence; (ii)
Genuity's willful misconduct; (iii) Genuity's indemnity obligations for
infringement pursuant to Section 10.1 of the Agreement; (iv) Genuity's
confidentiality obligation pursuant to Section 9 of the Agreement; (v)
imposition of fines or penalties on Bell Atlantic by any regulatory agency to
the extent imposition of such fines or penalties is caused by Genuity's SLA
failures.  Both Parties agree to monthly review meetings to discuss Service
Level performance related issues.  Genuity agrees to initiate and coordinate the
monthly review meetings.

1.   SONET Based Private Line Transport Service Overview

SONET Based Private Line Transport Service ("Private Line" or "Private Line
Service") products are point to point services derived from the basic SONET
building block of the Genuity backbone. Synchronous optical network (SONET)
defines optical carrier (OC) levels and electrical equivalent synchronous
transport signals (STS) for fiber optic based transmission hierarchy. It is a
standard specified by the Exchange Carriers Standards Association (ECSA) for
American National Standards Institute (ANSI). SONET uses a basic transmission
rate of STS-1 equivalent to 51.84 Mbps.

Higher rate transmissions are integer multiples of this base rate. Many types of
services ranging from voice to high-speed data and video are transmitted using
this format.

SONET provides the scalable bandwidth to transport information from one point to
another at a variety of speeds. Private Line Services can support the transport
of protocol services applied to voice or data service such as IP, ATM and Frame
Relay. These in turn support a range of applications used by Bell Atlantic
and/or Bell Atlantic End Users.

2.   Product Features and Functionality

2.1  High Level Functionality

There are three principal classes of service of Genuity Private Line Services
available each with a subset of configurations.

a.   End to End
b.   Access Hub to Access Hub
c.   Genuity POP to Genuity POP - This will become available with the
     introduction of direct optical connect and collocation as may be set forth
     in future amendments to the Agreement.

2.2  Product Features Set

Genuity is offering Private Line Services that include DS-3, OC-3, OC-12, OC-48
speeds.  The OC-3, OC-12, circuits may be concatenated, as well.

Genuity products will make use of the SONET pointer capabilities to dynamically
align VT and STS payloads, thereby permitting easy dropping, inserting and cross
connecting of payloads in the network. Additional use of the SONET capabilities
will be drawn on to provision 1+1 capabilities to support wholesale customer
demands.  The SONET rings on the Genuity backbone are four (4) fiber Bi-
Directional Line Switch Ring (BLSR).

2.3  Interconnection and Access

Bell Atlantic's interconnection to the Genuity network may be at the Access Hub
or Genuity POP.   The standard interconnection option for Bell Atlantic customer
provided access (CPA) services is at the Access Hub.  The Genuity backbone is
exclusively optical.  For Access Hub to
<PAGE>

Access Hub and Genuity POP to Genuity POP, Bell Atlantic is responsible for
access. The End to End Service includes Access in accordance with the terms in
the Service Schedule.

portions of this circuit may be linear.

2.4.6  Auto Restoral Time
<PAGE>

The Auto Restoral Time for a Private Line circuit (POP to POP only) on a SONET
ring is 50 - 110ms.  The SLA Credit/Remedy for Auto Restoral Time is accounted
for in the Circuit Availability SLA set forth in this document.  Auto Restoral
Time is not a parameter that is directly measured for SLA crediting.

2.4.7  Latency SLA Credit/Remedy

The Genuity SONET based Private Line Service is designed to meet the latency
requirements as shown in Table 2.4.1-1.  Latency is a function of circuit miles
traversed.  The one-way network latency is measured from the ingress interface
at the entry Genuity POP to the egress interface at the exiting Genuity POP.

Genuity shall agree to test latency on any circuit upon written request of Bell
Atlantic.  If the latency constitutes an SLA failure, Genuity shall have thirty
(30) days from the date of test completion to make the circuit SLA compliant.
If the latency is SLA compliant, Bell Atlantic agrees to reimburse Genuity for
commercially reasonable costs of the testing, not to exceed $1,000 plus travel
costs per test performed.  Bell Atlantic will have the option to request latency
test(s) on 1% of the installed circuit base or 5 per month, whichever is
greater. This SLA does not cover route specific requests from Bell Atlantic.

2.4.8  Installation Intervals SLA Credit/Remedy

If the actual installation date is more than five (5) business days beyond the
Projected Delivery Date contained in the FOC, Genuity shall waive the access
facility installation NRCs associated with the installation.  In addition, if
the actual installation date is more than fifteen (15) business days beyond the
Projected Delivery Date, Bell Atlantic has the option to cancel the Order with
no cancellation charges.

1.1 ATM Product Overview

     ATM is a high-bandwidth, fast-packet switching technology based on fixed-
length cells of 53 bytes.  ATM combines the statistical multiplexing
efficiencies of packet-switching with the low delay characteristics of circuit
switching technologies.   This document summarizes the ATM Transport Service
("ATM" or "ATM Service") and service level agreements (SLAs) provided by the
Genuity network for Bell Atlantic.

                Section 2   PRODUCT FEATURES AND FUNCTIONALITY

2.1 High Level Functionality Description

     Genuity ATM transport establishes ATM connections between a Bell Atlantic's
End User site and one or more locations, including, as applicable, a network
interconnection with Bell Atlantic. Each connection will be a permanent virtual
channel (PVC) or a permanent virtual path (PVP). Each supported ATM virtual
connection is a point-to-point (or point-to-interconnect) connection.  Genuity
ATM is connection-oriented, cell-based data transport capable of physical access
interconnection speeds from DS-3 to OC-12c Genuity, on an individual case basis,
will work to develop alternatives to provide Bell Atlantic customers lower speed
physical interconnections to the Genuity network when business economics
warrant.

2.2  Product Feature Set

2.2.1  Physical Connections

     The customer interfaces to the ATM Transport through DS3 (un-channelized),
OC-3c or OC-12c interfaces

     ATM cell formatting and traffic policing are compliant with the ATM Forum
UNI v3.0/3.1 Specifications.

2.2.2  Virtual Connections

The ATM Transport supports the following categories of traffic for virtual
connections:

                                       1
<PAGE>

A.  Constant Bit Rate (CBR): An ATM category that supports a constant or
    guaranteed rate to transport applications, such as video distribution, that
    require rigorous timing control and performance parameters. The traffic
    parameters associated with CBR are Peak Cell Rate (PCR), Cell Transfer Delay
    (CTD) and Cell Delay Variation (CDV).

B.  Real Time Variable Bit Rate (VBR-rt): The real-time VBR category is intended
    for time-sensitive applications (i.e., those requiring tightly constrained
    delay and delay variation), such as interactive multimedia. Sources are,
    however, expected to transmit at a rate that varies with time. Traffic
    parameters are PCR and Sustainable Cell Rate (SCR). Cells that are delayed
    beyond CTD are assumed to be of significantly less value to the application.
    Default value for PCR is set at 1.4 times SCR. Maximum Burst Size (MBS) is
    also a traffic parameter for the real-time VBR with a default setting of 100
    cells.

C.  Non-Real-Time Variable Bit Rate (VBR-nrt): The non-real time VBR category is
    intended for applications which have bursty traffic characteristics and do
    not have tight constraints on delay and delay variation. Like VBR-rt, VBR-
    nrt traffic parameters are PCR and SCR. For those cells that are transferred
    within the traffic profile, the application expects a low CLR. Default value
    for PCR is set at 2.0 times SCR. Maximum Burst Size (MBS) is also a traffic
    parameter for the non-real time VBR service categories with a default
    setting off 100 cells

D.  Unspecified Bit Rate (UBR): An ATM category that does not specify traffic
    related performance guarantees. Specifically, UBR does not include the
    notion of a per-connection negotiated bandwidth. No numerical commitments
    are made with respect to the CLR experienced by a UBR connection, nor to the
    CTD experienced by cells on the connection.

For both PVC and PVP transport, the traffic profile may be subscribed for each
direction of the connection independently. The values for the parameters
indicated above are set forth in the data gathering form negotiated with the
customer. For the PVP option, the subscribed traffic profile must be able to
satisfy the QoS of the most demanding virtual channel connection (VCC) that may
be carried on that virtual path connection (VPC).

2.3  Technology Overview

2.3.1  Genuity ATM Switches
Genuity selected the Ascend models CBX-500 & GX-550 switch as its core network
ATM switches.

2.3.2  Integrated Local Management Interface (ILMI)
The Genuity ATM transport is compliant with the following ATM Forum
specifications:

A.   ATM User-Network Specification V3.0, af-uni-0010.001, ATM Forum Technical
Committee, Sept 1993
B.   ATM User-Network Specification V3.1, af-uni-0010.002, ATM Forum Technical
Committee, 1994
C.   ILMI 4.0, af-ilmi-0065.000, ATM Forum Technical Committee, Sept 1996
Bell Atlantic's and Bell Atlantic's End Users' ATM equipment must be similarly
compliant with the above specifications.

2.4  Product Functionality

2.4.1  Asymmetric PVCs
PVCs are bi-directional circuits, and typically but not necessarily, these
parameters are configured to be the same information rates in both directions.
However, the business needs of Bell Atlantic may require that additional
bandwidth be allocated in one direction and not the other direction. Genuity's
ATM transport enables Bell Atlantic to provision and price PVCs, as two unique
asymmetric PVCs, with different information rates between its locations.

2.4.2  Performance and Reliability Requirements

2.4.2.1  Network Availability
The Genuity ATM transport is designed meet the availability requirements as
shown in Table 2.4.4-1. A connection is considered available if it is possible
to transmit bits through the connection.

For each Point of Presence to Point of Presence (POP-to-POP) connection,
availability values are from the ingress interface at the entry on-right of way
Genuity POP to the egress interface at the exit on-right of way Genuity POP, and
include any on-right of way back-haul between the points of Bell Atlantic/Bell
Atlantic End User interconnection and the Genuity's ingress/egress ATM switches
for each ATM network ordered by Bell Atlantic hereunder (i.e. Interconnection
point(s) to the Bell Atlantic network are considered as POP/POP equivalent(s)).

                                       2
<PAGE>

For each End-to-End connection, availability values are from the network entry-
point, CSU/DSU, at the Bell Atlantic End User's premise to the network exit-
point, CSU/DSU, at the Bell Atlantic's End User premise. To provide this level
of transport, Customer Premise Equipment must be certified for compatibility on
the Genuity network.  Customer premise equipment requiring certification
includes, but is not limited to, CSU/DSU equipment and routers.  Genuity follows
the Lucent certified list of CPE vendors. These vendors include, but are not
limited to: Cisco, Nortel Networks, 3Com, Adtran, and Visual Networks (i.e. End-
to-Interconnection point(s) to the Bell Atlantic network are considered as End-
to-End-equivalent(s)).

As additional requirements are identified, Genuity will make commercially
reasonable efforts to augment the list of certified vendor equipment based on
market demand.

2.4.2.2  Cell Latency
Network latency or end-to-end delay is largely a function of circuit miles
traversed.  The one-way network latency is measured from the ingress interface
at the entry Genuity POP to the egress interface at the exiting Genuity POP.

The Genuity ATM network is designed to meet the latency values shown in Table
2.4.4-1

2.4.2.3  Cell Loss
The cell loss ratio (CLR) for ATM transport is defined in the ATM Forum Traffic
Management Specification, Version 4.0 (af-tm-0056.000).  Cell Loss Ratio is the
(total cells lost) divided by (total cells delivered).  The Genuity ATM network
is designed to meet the cell loss ratio values shown in Table 2.4.4-1

Cell loss due to saturation of an oversubscribed/1/ egress port is not
considered a failure on Genuity's part to meet the CLR performance
characteristics.

2.4.2.4  Peak to Peak Cell Delay Variation
The Genuity ATM network is designed to meet the peak-to-peak CDV values shown in
Table 2.4.4-1

2.4.2.5  ATM Maximum Burst Size
The default values for VBR-rt and VBR-nrt maximum burst size is 100 cells.  On
an individual case basis, requests for higher values will be reviewed for
feasibility.

2.4.2.6    ATM Over-subscription Parameters
Genuity ATM transport will allow port over-subscription values for VBR-rt and
VBR-nrt.

                        Transport Element              Value

                       --------------------------------------

Note these numbers represent the total port bandwidth allocations, but that they
may not all be simultaneously active at the same time.

2.4.3  Fraud Control Requirements
The primary goal of the Genuity's network security architecture is to protect
Genuity resources and reputation by securing its infrastructure and operations.
Protection of end user's traffic and sites is not a Genuity responsibility;
rather it is an end user responsibility.

/1/ In this statement "Oversubscribed" is defined as when the aggregate
equivalent bandwidth for circuits requested on a port exceeds the port's
capacity to carry all such circuits simultaneously.

</TABLE>
General ATM SLA terms and specific remedies are described in sections 2.4.4-1
through 2.4.4-18.

2.4.4.1  Measurement Period
SLAs are measured on a calendar month basis.

2.4.4.2  Commencement of SLA Credits
Circuits require a full calendar month of measurable activity. No credits will
be given for partial month activity.

2.4.4.3  Network/Circuits Covered by SLA
Service level agreements include all ATM circuits and ATM Networks ordered
hereunder for Bell Atlantic and Bell Atlantic's End User's.  Network
calculations are measured as average network availability and average cell loss
rates. Calculations are made separately on each ATM network and each ATM circuit
ordered by Bell Atlantic.

2.4.4.4  Remedies for Average Network Availability and Average CLR SLA
Genuity's failure to meet the Average Network Availability and/or CLR SLAs will
result in a percentage credit on Bell Atlantic's ATM bill for the following
month for the affected ATM network. The SLA credit percentage is dependent on
the number of consecutive months of SLA failure and the degree of failure.

-----------------------------
/2/ Bell Atlantic may select only one of the 3 (POP-to-POP or the End-to-End)
average network availability credits each month.  GNI will compute proactive
credits each month based on the POP-to-POP availability.
/3/ The End-to-End with High Availability Tails Network Availability SLA
requires that a Bell Atlantic purchase SONET local loops.   High availability
local loops are not available to all Bell Atlantic End User locations.
/4/ Customers may select only one of the 3 (POP-to-POP or the End-to-End) per
PVC network availability credits each month.

                                       4
<PAGE>

The number of consecutive months creates the base credit percentage and the
degree of failure creates a multiplier. If the SLA failure is for one single
month or for two consecutive months, then the base credit percentage is two
percent (2%). If the consecutive SLA failure continues for a third or fourth-
consecutive month, then the base credit percentage is four percent (4%). If the
SLA failure continues for a fifth or greater consecutive month, then the base
credit percentage is six percent (6%).

The following sets forth the multipliers:

i)   For the Average Network Availability SLA, the multiplier is the number of
     tenths below the average network availability parameter set forth in Table
     2.4.4-1; and

ii)  For the CLR SLA, the multiplier is the number of power of tens (1 x 10/+1/)
     above the SLA value for the class of service as specified in Table 2.4.4-1.
     With the first power of ten increase in CBR and VBR-nrt representing a
     failure to meet the SLA Infraction Level.

2.4.4.5  SLA Credit Policies

The following SLAs on a POP to POP basis will be proactively credited, and are
based on the Monthly Network Throughput and Network Availability Threshold
Report Records: Average Network Availability and Average Cell Loss Ratio.  All
other SLA remedies will be applied upon Bell Atlantic request and verification
by Genuity of SLA failure. Upon Bell Atlantic request, per Circuit credits will
be verified and applied in the amount by which the aggregate Per Circuit SLA
Credits exceed the Network level credit.

2.4.4.6  Verification of Non-Compliance

Genuity is responsible for verifying SLA non-compliance, not later than the
calendar month following the SLA failure, prior to crediting a customer's
account.

2.4.4.7  Time to Restore

Genuity will use commercially reasonable efforts to keep the Time to Restore
(TTR) under four hours (95% of the time) as measured over a one month period.
TTR is not a parameter that is directly measured for SLA crediting, however TTR
by its very nature is a factor in the computation of the overall Average Network
Availability

2.4.4.8  Exclusions from computation of SLA Failures

Each timeframe with data exclusion will be reflected as such in the Summary
Circuit Records. Oversubscribed circuits are eligible for Availability
Performance credits, however oversubscribed circuits are not eligible for Cell
Loss Violation credits. See the Section entitled "Service Level Agreements for
Services" in the Service Schedule for all other authorized exclusions in
addition to any other exclusions specifically identified.

2.4.4.9  CLR Allowance for Sample Period Errors

Computation of CLRs is based on reading and aggregating ingress and egress ATM
cell count statistics across each ATM network ordered by Bell Atlantic
hereunder. An allowance is made for cells in transit and cells not accounted for
due to the switches operating with timing set utilizing the Network Timing
Protocol (NTP) or equivalent level of accuracy.

2.4.4.10  Action Required of Genuity after 2 Months of Circuit Performance
          Violations

If an ATM circuit fails to meet the Per PVC Availability SLA and/or Per PVC CLR
SLA for two (2) consecutive months, Genuity will use commercially reasonable
efforts to coordinate (with Bell Atlantic approval) an alternate connection
until such time as the original connection meets such SLA performance standards.
Prior to reaching this two month maximum period Genuity may at its sole
discretion exercise these same provisions.  In the event Genuity performs
pursuant to this provision Genuity is relieved from its obligations set forth
below in 2.4.4.11.

2.4.4.11  Bell Atlantic Right to Terminate Networks

For Bell Atlantic End Users with ATM networks that operate for 3 consecutive
months or 5 months out of any 12 months with Average Network Availability and/or
Average Network CLR SLA failure violations, Bell Atlantic has the option to
terminate the affected End User ATM network without liability, except for
charges incurred prior to discontinuance.  Should Bell Atlantic decide to
terminate such Service, Bell Atlantic must provide written notice to Genuity of
its intent to disconnect no later than 30 days following the conclusion of the
3/rd/ consecutive month or 5/th/ month out of any 12 month period of Service
with such SLA violations.

2.4.4.12  Bell Atlantic Right to Terminate Circuits

For Bell Atlantic End Users with circuits that operate for 3 consecutive months
or 5 months out of any 12 months with Per PVC Availability and/or Per PVC CLR
SLA failure violations, Bell Atlantic has the option to terminate the affected
circuits without liability, except for charges incurred prior to discontinuance.
Should Bell Atlantic decide to terminate such circuits, Bell Atlantic must
provide written notice to Genuity of its intent to disconnect no later than 30
days following the conclusion of the 3/rd/ consecutive month or 5/th/ month out
of any 12 month period of service with SLA violations. Circuit terminations due
to Cell Latency or Peak to Peak Cell Delay Variation SLA failure conditions are
described in sections 2.4.4.15 and 2.4.4.16.

2.4.4.13  Per Virtual Circuit CLR Remedies

Notwithstanding the provisions contained in 2.4.4.14, 2.4.4.15, 2.4.4.16;
credits for individual PVCs and PVPs that exceed the Per PVC Cell Loss Ratio SLA
failure shall be equivalent to 50% of the MRC for the impacted PVCs.

2.4.4.14  Per Virtual Circuit Availability Remedies

Credits for individual PVCs and PVPs that exceed the Per PVC Availability SLA
failure level shall be the percentage of MRC specified in the tables 2.4.4.14-1
through 2.4.4.14-3 below. Per Virtual Circuit credits

                                       7
<PAGE>

are not additive, however Bell Atlantic may select the higher of the two credits
that apply to a circuit that has exceeded both a POP to POP and an End to End
SLA failure level.

2.4.4.15  Cell Latency SLA Remedies

Genuity shall test Bell Atlantic's circuits from POP to POP or End to End to
verify Cell Latency performance upon request of Bell Atlantic.  If the Cell
Latency is within SLA, the cost of the testing shall be assessed to Bell
Atlantic. In this event, Bell Atlantic shall reimburse Genuity commercially
reasonable costs of the testing, not to exceed $1000 plus travel costs for each
test performed.  If the Cell Latency is not within SLA, Genuity shall have 30
days from the date of Bell Atlantic's trouble report to restore the Cell Latency
to comply with the SLA.  If Genuity can not restore the Cell Latency, Bell
Atlantic shall have the right to terminate the affected circuit at no cost.

2.4.4.16  Peak to Peak Cell Delay Variation SLA Remedies

Genuity shall test Bell Atlantic's circuits from POP to POP to verify Peak to
Peak Cell Delay Variation performance upon request of Bell Atlantic.  If the
Peak to Peak Cell Delay Variation is within SLA, the cost of the testing shall
be assessed to Bell Atlantic. In this event, Bell Atlantic shall reimburse
Genuity commercially reasonable costs of the testing, not to exceed $1000 plus
travel costs for each test perfomed.  If the Peak to Peak Cell Delay Variation
is not within SLA, Genuity shall have 30 days from the date of Bell Atlantic's
trouble report to restore the Peak to Peak Cell Delay Variation to comply with
the SLA.  If Genuity can not restore the Peak to Peak Cell Delay Variation, Bell
Atlantic shall have the right to terminate the affected circuit at no cost.

2.4.4.17  Installation Interval SLA Remedies

If actual installation date is more than 5 business days beyond the Projected
Delivery Date contained in the FOC, Genuity shall waive the access facility
installation NRCs, associated with the installation.  In addition, if actual
installation date is more than 15 business days beyond the Projected Delivery
Date, Bell Atlantic has the option to cancel the Order with no cancellation
charges.

2.4.4.18  CLR Allowance for SONET Layer Defined Fault Protection Mechanism

                                       8
<PAGE>

Since the computation of CLRs is based on reading and aggregating ingress and
egress ATM cell count statistics across the network, a dropped cell allowance is
made for cells in transit that are computed as lost cells due to Protection
Switchover (1 second of lost data per protection switch event).

        Section 4  Terms and Conditions associated with the ATM Pricing

ATM transport is provided as a distance insensitive capability. PVCs and PVPs
are priced unidirectional.  The Peak Cell Rate (PCR) of VBR PVCs and PVPs is
governed by the SCR ordered Bell Atlantic: in the flat rate PVC/PVP offering,
VBR-rt PCR is 1.4 multiplied by the SCR; and the VBR-nrt PCR is 2.0 SCR.
Request for PCRs with multipliers greater than those stated above shall be
supported at an increased cost.  UBR transport is only available in conjunction
with the active use of another ATM transport category on the same port and is
limited to 40 Mbps.  Maximum burst size (MBS) is limited to 100 cells. Request
for larger burst sizes shall be supported at an increased cost.

ATM - PVC Mapping and Configuration
================================================================================
*Note* -A key element to remember when requesting ATM-PVCs. With GNI each PVC is
uni-directional. If your customer requires a bi-directional PVC from one
location to another, you will need to enter an order for 2 PVCs; one for each
direction. When you enter the PVC # use a Number/Letter combination to relate
them (ex. 1A and 1B, 2A and 2B, 3A and 3B, etc.)

                                EXPEDITE PROCESS

STEP 1: IF BELL ATLANTIC REQUIRES A SERVICE INTERVAL OF LESS THAN THE STANDARD
INTERVAL IN THE SERVICE SCHEDULE, BELL ATLANTIC SHALL COMPLETE THE ATTACHED
EXPEDITE REQUEST FORM (ERF) AS MAY BE MODIFIED BY GENUITY FROM TIME TO TIME AND
FORWARD IT TO THE GENUITY CHANNEL MANAGER.  EXPEDITES WILL NOT BE ACCEPTED FOR
AN INTERVAL OF LESS THAN TEN (10) BUSINESS DAYS FOR NEW ORDERS, AND WILL NOT BE
ACCEPTED FOR AN INTERVAL OF LESS THAN FIVE (5) BUSINESS DAYS FOR CHANGE ORDERS.

Step 2: Genuity will convey the acceptance or rejection of the request to Bell
Atlantic within three (3) business days of Genuity's receipt of Bell Atlantic's
request.  If the request is accepted, the response will include Genuity's
ability to meet the expedited due date or such other date as Genuity is able to
meet.  If the request is rejected, Genuity shall provide the specific reason(s)
for the rejection.

Step 3: If Bell Atlantic accepts the Genuity expedite, Bell Atlantic will notify
Genuity within one (1) business day of such acceptance and the expedite fee will
apply as follows:

Expedite Fees:
     Bandwidth          New Orders      Change Orders

     DS3               $1,000           $  500
     OC3/OC3c          $1,500           $  750
     OC12/OC12c        $2,500           $1,250
     OC48+             $4,500           $2,500

Step 4: Bell Atlantic will place the Order with the approved expedited due date.

NOTES:
1.  GENUITY WILL FULLY WAIVE THE EXPEDITE FEE TO BELL ATLANTIC IF THE APPROVED
    EXPEDITED DUE DATE IS MISSED.

2.  Expedite requests on any pending Order will be accepted until the FOC is
    issued.  If Bell Atlantic decides to expedite a pending Order, the expedite
    process will take effect, rendering the previous Order null and void.

                               Trouble Reporting

When reporting a fault to the Genuity GNOC, Bell Atlantic shall supply as much
diagnostic information as it reasonably has available. Genuity will initiate
fault reporting directly when it is reasonably able to do so.

Genuity shall utilize industry-standard fault detection tools. When a fault is
detected, such fault will be logged by Genuity GNOC staff. Genuity shall also
utilize industry standard fault management tools, and will notify Bell Atlantic
from time to time of any modification to the tools it is deploying.

The Genuity GNOC shall be responsible for resolving the fault, and shall
maintain auditable records of all such resolutions. At all stages during the
fault resolution process, the Genuity GNOC shall remain the single point of
contact for Bell Atlantic. The Genuity GNOC will provide regular status updates,
according to accepted industry standards, as a reported fault progresses toward
resolution. Genuity shall categorize all faults in accordance with the severity
levels indicated in the Severity Level Matrix below. Upon identifying a fault or
a non-conforming condition, the Genuity GNOC will categorize the incident
according to its agreed severity in accordance with the Severity Level Matrix.
Where appropriate, Bell Atlantic will consult with the Genuity GNOC as to the
potential business impact and may verbally or electronically require a
modification to the severity level accordingly.

Fault tickets shall only be closed by Genuity when Bell Atlantic has confirmed
trouble resolution. Fault summaries and Fault status will be provided to Bell
Atlantic on a daily, weekly and monthly basis by the Genuity GNOC.

Severity Level Matrix
The severity matrix below indicates the level of urgency for an event:

------------------------------------------------------------------------------------------------------------------------------------
1.   GNI systems will use Simple Network Management Protocol (SNMP), to access partner's network for service, configuration, fault
     and performance information, on a near real time basis.
2.   Statistical information must be available and refreshed in an agreed upon discrete interval (For example, every 15 minutes.
3.   Fault information should be available in the form of a SNMP trap. The trap must be available within a minute of its occurrence.
4.   Configuration information must be refreshed at least, once every twenty-four hours.
5.   Partner must retain the statistics and fault history at least up to 5 days. It is also preferred if the information is
     available via industry standard interfaces such as ODBC.
6.   Bell Atlantic Global Networks, inc., recommends that partners deploy highly available systems architecture for information
     access.

                   PURCHASE, RESALE AND MARKETING AGREEMENT
                               SERVICE SCHEDULE
                    PURCHASE OF CAPACITY ON UNDERSEA CABLES

This Service Schedule is issued under the Purchase, Resale and Marketing
Agreement between Bell Atlantic Corporation ("Bell Atlantic") and Genuity Inc.
("Genuity") dated ____________ ("the Agreement"). As stated below, the terms and
conditions of the Agreement are incorporated herein by reference and made a part
hereof. In the event of a conflict between the terms of this Service Schedule
and the Agreement, the terms of this Service Schedule shall prevail. Capitalized
terms are defined in the Agreement. Pursuant to Section 1.1 of the Agreement,
Genuity designates GTE Intelligent Network Services Incorporated as the Service
Provider for provision of the undersea capacity Services under this Service
Schedule.

1.   Capacity on ARCOS-1 Undersea Cable. Genuity will provide to a Bell Atlantic
     ----------------------------------
Authorized Affiliate capacity in the amount of an STM-1 on the Americas Region
Caribbean Ring System undersea cable ("ARCOS-1"), at Genuity's cost. Such cost
will reflect a pro rata share of the costs incurred by Genuity associated with
ARCOS-1, based on the percentage that the STM-1 constitutes of Genuity's total
number of STM-1s (or equivalent) on ARCOS-1. The costs will include, but are not
necessarily limited to, charges imposed under the ARCOS-1 Construction and
Maintenance Agreement and collocation at the cablehead. Within five (5) business
days of availability of undersea capacity Service on ARCOS-1, Genuity will
provide the Bell Atlantic Authorized Affiliate with additional details
concerning the costs and processes for provisioning such Services. The agreement
set forth in this Service Schedule is based on the fact that the Genuity
capacity commitment on ARCOS-1 was based in part on a commitment for the
specified STM-1 by a Bell Atlantic affiliate. Provision of the capacity under
this Agreement is intended to implement the parties' original understanding
concerning the ARCOS-1 cable.

2.   Capacity on Americas III Undersea Cable. Genuity is currently participating
     ---------------------------------------
in the negotiations of the Americas III Cable Network Construction and
Maintenance Agreement (C&MA). Upon substantial completion of the C&MA, Genuity
and Bell Atlantic will discuss the options associated with obtaining capacity on
Americas III, including whether one will sell or assign Americas III capacity to
the other. Alternatively, each may sign the C&MA independently.

3.   Provisions Applicable to Undersea Cable Capacity. Sections 2, 4, 6, 9, 10,
     ------------------------------------------------
13 and 14 of the Agreement apply to the Provision of such undersea capacity
Services as set out in this Service Schedule. The remaining provisions of the
Agreement are superseded by this Service Schedule and by the terms of the
applicable agreement governing the ARCOS-1 or Americas III cable. Payments for
such undersea capacity Services do not apply toward the Purchase Commitment as
described in Section 7.3 of the Agreement.

<PAGE>

         (d) The license provided by this Section 3.1 shall not be sublicensable
or transferable, in whole or in part, to any third party and is in addition to,
and shall not be construed as limiting or expanding in any way, any other
licenses that GTE has granted or will grant to GENUITY under GTE Intellectual
Property Rights.

         3.2. Certain License Limitations.

         (a) The license right granted in Section 3.1 shall not include any
right to: (i) copy or reproduce, modify, market, sublicense, transfer or
distribute the Licensed Software, or any portion thereof, in any manner

license grant does not include any license, right, title or interest in or to
any Third Party Software or other technology of any third party, or any
Intellectual Property Rights therein, required for GENUITY to exercise its
rights hereunder. To the extent any Third Party Software is provided by GTE to
GENUITY pursuant to this Agreement, the Use of such Third Party Software shall
be pursuant to the terms and conditions of this Agreement, unless a Third Party

instance GTE shall use its best efforts to advise GENUITY of that fact, and such
Third Party Software license agreement shall govern the Use of such Third Party
Software.

         (b) The license right granted in Section 3.1 is for Object Code only
and does not include a license or any other rights to the source code or other
mnemonic or high-level statement version of the Licensed Programs or any
documentation therefor. Without limiting the foregoing, GENUITY shall not
decompile, disassemble, reverse analyze or reverse engineer any Licensed
Software, or otherwise attempt to discover, generate, use or modify the
structural framework or source code of any Licensed Software, or permit or
authorize any person or entity to do so.

         (c) Nothing herein shall be construed as granting GENUITY, by
implication, estoppel or otherwise, any license or other right under any
Intellectual Property Right of GTE, including without limitation, any such
license or right in or to the Licensed Software, except for the license
expressly granted in Section 3.1.

sole and exclusive owner of GTE Products, and any and all Intellectual Property
Rights therein and (ii) the third party is and shall remain the sole and
exclusive owner of Third Party Software, and any and all Intellectual Property

GENUITY agrees neither to do nor to permit any act which may in any way
jeopardize or be detrimental to the validity of GTE's Intellectual Property
Rights in GTE Products of the third party's Intellectual Property Rights in the
Third Party Software.

4. Payments

         4.1. Payments. In consideration for the rights and licenses granted
herein by GTE for the Use of each Licensed Software and for the Maintenance and
Support Services for such Licensed Software provided by GTE hereunder, GENUITY
shall pay GTE the annual license fee specified for each Licensed Software set
forth in Schedule A hereto; said annual license fee specified in Schedule A
shall be applicable only to the first year of the License Term, with the annual
license fee thereafter being GTE's then applicable annual license fee (which
includes Maintenance and Support Services) charged to third parties who are not
Affiliates of GTE (or if there is no annual license fee (which includes
Maintenance and Support Services) for third party licensees of the Licensed
Software, the amount set forth on the applicable invoice to GENUITY). GTE shall
invoice GENUITY for such annual license fee on the Effective Date and on each
anniversary thereafter during the License Term, and payment shall be due from
GENUITY on or before the thirtieth (30th) day following receipt by GENUITY of
such invoice. All payments shall be made in United States currency, shall be
nonrefundable and paid fully net, without set-off, deduction or counterclaim
unless expressly provided otherwise hereunder, and shall be made by wire
transfer to such bank account(s) as GTE may specify in writing.

         4.2. Late Payments. GENUITY shall pay interest on any late payments at
a rate equal to the lesser of (i) 18% per annum and (ii) the maximum rate of
interest allowable under applicable law.

         4.3. Taxes. In addition to the charges payable for services and rights
and licenses provided hereunder by GTE, GENUITY shall pay GTE an amount equal to
any sales, use, privilege, gross revenue, excise or any other tax (except income
and franchise taxes), as well as any assessments or duties lawfully levied by a
duly constituted governmental authority and for which GTE is required or
permitted, by law, to collect from GENUITY with respect to the services,
materials and rights provided under this Agreement. In addition, GENUITY shall
be responsible for all real and personal property taxes imposed on Licensed
Software in GENUITY'S possession on January 1 of every year. If GENUITY
determines that any services, materials or rights obtained from GTE are exempt
from a tax, GENUITY must provide GTE a properly completed exemption certificate,
for all jurisdictions for which GENUITY is claiming an exemption, before GTE
will exclude the respective tax from amounts charged to GENUITY. GENUITY shall
not deduct any tax amount from remittances to GTE until a properly completed
exemption certificate, for all jurisdictions for which GENUITY is claiming an
exemption, has been provided to GTE.

<PAGE>

5. Delivery.

         5.1. Delivery of Licensed Software. Unless otherwise already in the
possession of GENUITY, as soon as practicable after the Effective Date of this
Agreement, but in any event within thirty (30) days thereafter, GTE shall
deliver to GENUITY a number of copies of each item comprising the Documentation
and the Licensed Programs; provided, however, the number of copies of Licensed
Programs shall in no event not exceed the number of Designated Systems.

         5.2. Updates. Any Updates to the Licensed Software shall be provided
pursuant to the IT Transition Services Agreement. Any Use or other exploitation
in any manner of any Updates shall be subject to all terms and conditions of
this Agreement.

         5.3. New Products. Any New Products developed or made available by GTE,
during the License Term, for Use with or as a replacement for Licensed Software
shall be offered to GENUITY at GTE's then-current published license fees, terms
and conditions.

         5.4. Maintenance and Support Services. Except as otherwise required for
GTE to satisfy its obligations contained in Section 8.3 hereof, GTE's sole
obligation to provide any maintenance and support services hereunder shall be
set forth in the IT Transition Services Agreement.

6. Indemnity for Infringement of Third Party Intellectual Property.

         6.1. Indemnity. If Licensed Software becomes the subject of an
infringement claim, or in GTE's opinion is likely to become the subject of such
a claim, then, in addition to defending the claim and paying any damages and
attorneys' fees finally awarded by a court of final jurisdiction, GTE may, at
its option and in its sole discretion, and at its own cost and expense: (i)
replace or modify such Licensed Software to make it noninfringing or cure any
claimed misuse of any third party trade secret; (ii) procure for GENUITY the
right to continue Using such Licensed Software pursuant to this Agreement; or
(iii) require the return of such Licensed Software and terminate GENUITY's right
to Use the same and refund to GENUITY a pro-rata portion of the current annual
license fee actually paid to GTE by GENUITY for the Use of such Licensed
Software. Notwithstanding the foregoing, if GTE exercises its right to require
the return of such Licensed Software and terminates GENUITY's right to Use the
same, to the extent permitted by applicable law, GENUITY may retain and continue
to Use such Licensed Software to the extent GENUITY agrees in writing to defend
and indemnify GTE for any and all expenses, costs and liabilities associated
with such continued possession and Use of such Licensed Software.

         6.2. Limitations. GTE shall not be liable to GENUITY for any claims of
inducement of infringement or contributory infringement or claims of
infringement resulting from the combination of the Licensed Software with the
products or services of third parties. Further, GTE shall have no liability to
GENUITY hereunder if (i) the claim of infringement is based upon the Use or
other exploitation of Licensed Software provided by GTE hereunder in connection
or in combination with equipment, devices, data or software not supplied by GTE,
and such infringement would not have occurred but for such Use; (ii) such
Licensed Software is Used outside of the scope of the rights and licenses
granted to GENUITY or in a manner for which the Licensed Software was not
designed; (iii) the Licensed Software or any portion thereof is modified by or
for GENUITY (even by GTE at GENUITY's direction or instructions), and such
infringement would not have occurred but for such modification; or (iv) GENUITY
Uses the Licensed Software as part of a patented process and there would be no
infringement in the Use of the Licensed Software alone. For all of the foregoing
exclusions, GENUITY shall defend and indemnify GTE for any infringement claims
to the extent set forth in Section 6.1.

                                       6
<PAGE>

         6.3. Procedure. The indemnification obligations set forth in this
Section 6 shall not apply unless GENUITY: (i) uses its best efforts to notify
GTE promptly in writing of any claims, charges of infringement or litigation in
order to allow GTE the opportunity to investigate and defend the matter;
provided, however, that the failure to so notify shall only relieve GTE of its
obligations under this Section 6 if and to the extent that GTE is prejudiced
thereby; and (ii) gives GTE full control of the response thereto and the defense
thereof, including, without limitation, any agreement relating to the settlement
thereof; provided, however, that GENUITY shall have the right to participate, on
a non-interfering basis, in any legal proceeding to contest and defend a claim
for infringement and to be represented by legal counsel of its choosing, all at
GENUITY's sole cost and expense. However, if GTE fails to promptly assume the
defense of the claim, GENUITY may assume the defense at GTE's cost and expense.
GTE shall not be responsible for any settlement or compromise made without its
prior written consent, unless GENUITY has tendered notice and GTE has then
refused to assume and defend the claim and it is later determined that GTE was
obligated to assume and defend the claim. GENUITY agrees to cooperate in good
faith with the GTE at the request and expense of GTE.

         6.4. The foregoing sets forth GTE's sole and exclusive obligations, and
GENUITY's sole remedies, for infringement of any Intellectual Property Rights by
any GTE Products.

7. Other Obligations of GENUITY and GTE.

         7.1. Third Party Software. GENUITY acknowledges that, in order to
exercise any rights granted by the license set forth in Section 3.1, including,
without limitation, Using the Licensed Software as expressly provided thereby,
GENUITY may need to license or otherwise obtain permission to Use Third Party
Software. Such licenses or other permissions shall be at GENUITY's sole cost and
expense and GENUITY shall be solely responsible for observing and complying with
the terms and conditions under which Third Party Software is licensed. GTE shall
use its best efforts to inform GENUITY of any Third Party Software that, to
GTE's knowledge, is required to Use the Licensed Software.

                                       7
<PAGE>

         7.2. Inspection of Facilities. GENUITY shall advise GTE in writing of
the location of all facilities at which it is carrying out activities subject to
license under this Agreement, including, without limitation, the location of any
Designated Systems. GTE may, from time to time, as it deems necessary, at its
sole risk and expense, enter such facilities, or any of them, and conduct such
inspection as is reasonably necessary to verify the nature of GENUITY's
activities and GENUITY's compliance with this Agreement. GENUITY shall provide
reasonable assistance to GTE for such inspection, GTE shall minimize the amount
of time that it is required to spend in GENUITY's facilities, and GTE shall
coordinate all such activities with GENUITY so as not to unreasonably interfere
with GENUITY's operations.

         7.3. Interoperability. If the provisions of the Council of European
Communities Directive of May 14, 1991 on the Legal Protection of Computer
Programs (the "Software Directive") apply to GENUITY's Use of the Licensed
Programs, and GENUITY wishes to obtain the information necessary to achieve
interoperability of an independently created computer program with the Licensed
Programs as permitted under Article 6 of the Software Directive
("Interoperability Information"), then GENUITY shall notify GTE in writing,
specifying the nature of the Interoperability Information it needs and the
purpose for which it will be used. If GTE reasonably determines that GENUITY is
entitled to such Interoperability Information under said Article 6, GTE shall,
at its option, either (i) provide such Interoperability Information to GENUITY
or (ii) authorize GENUITY to reverse engineer the Licensed Programs, within the
time limits prescribed by said Article 6, solely to the extent indispensable to
obtain such Interoperability Information. If GTE elects clause (i), GENUITY
shall provide all information and assistance reasonably requested by GTE to
enable GTE to perform clause (i), and GTE may charge GENUITY a reasonable fee,
determined in GTE's discretion, for making available the requested
Interoperability Information, unless such a fee is prohibited under
said Article 6.

8. Warranties.

         8.1. Allocation of Risk. An essential purpose of the exclusion of
warranties and limitation of liability provided in this Agreement is allocation
of risks between GTE and GENUITY, which allocation of risks is reflected in the
arrangements between GTE and GENUITY contained in this Agreement.

         8.2. No Conflicts. GTE warrants that, to the best of its knowledge, it
owns, or otherwise has, the necessary Intellectual Property Rights to grant the
licenses, rights and permissions contained herein.

                                       8
<PAGE>

         8.3. Conformance Warranty. GTE warrants to GENUITY that (i) with normal
service and use, each of the Licensed Programs, including, without limitation,
Updates, shall, at the time of first delivery to GENUITY of the Licensed
Programs and for a period of thirty (30) days thereafter, conform substantially
on the Designated Systems to either the Documentation or the specifications
included in Schedule B, as applicable; provided, however, that such Licensed
Program has not been modified or altered by GENUITY or any other person or
entity, has not been abused or misapplied, has not been Used outside of the
scope of the rights and licenses granted pursuant to this Agreement, and has not
been Used in combination with hardware or software other than the Designated
Systems. The warranty set forth in this Section 8.3 shall be void if GENUITY
fails to submit timely a completed report to GTE describing the condition that
GENUITY believes constitutes a breach of said warranty, together with removable
machine-readable media on which GENUITY has made a copy of that portion of the
Licensed Program that GENUITY believes to contain such condition, within twenty
(20) days after GENUITY discovers such condition. GENUITY's sole and exclusive

such nonconforming Licensed Program; or if GTE is unable to make any Licensed
Programs operate as warranted hereunder, to refund any payments on a pro-rata
basis actually made by GENUITY to GTE hereunder for such nonconforming Licensed
Program during the last year of the License Term.

LOSS OF USE), WHETHER BASED ON CONTRACT, TORT (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE), OR ANY OTHER CAUSE OF ACTION RELATING TO GTE PRODUCTS, OR OTHERWISE

and except and to the extent expressly provided for in Section 6, GTE shall
under no circumstances be liable for any claim or demand by any third party

errors in GENUITY's Use of the Licensed Software or any other GTE Products or
Services. GENUITY shall indemnify and hold GTE harmless from and against any
loss, cost or damages, including, without limitation, reasonable attorneys' and
professionals' fees, arising in connection or as a result of such claim or
demand.

         10.1. Restrictions. GENUITY shall: (i) use Confidential Information
only in connection with fulfilling its obligations and exercising its rights
hereunder; (ii) hold Confidential Information in strict confidence and exercise
due care with respect to its handling and protection, consistent with GENUITY's
own policies concerning the protection of its own confidential information of
similar importance, but in no instance less than reasonable care; (iii) not
disclose, divulge or publish Confidential Information or any portion thereof,
except to such of its responsible employees who have a bona fide need-to-know to
the extent necessary to exercise GENUITY's rights and licenses under this
Agreement and are who are bound in writing to maintain the confidentiality of
such Confidential Information; (iv) instruct all such employees not to disclose
Confidential Information to third parties; (v) not remove any titles,
trademarks, copyright, patent and other proprietary rights notices set forth on

expressly permitted hereunder and necessary to exercise its rights and licenses
hereunder.

         10.2. Compliance with Governmental, Judicial Requirements.
Notwithstanding anything herein to the contrary, if GENUITY receives a request
to disclose any Confidential Information (whether pursuant to a valid and
effective subpoena, an order issued by a court or other governmental authority
of competent jurisdiction or otherwise) on advice of legal counsel that
disclosure is required under applicable law, GENUITY agrees that, prior to
disclosing any Confidential Information, it shall (i) notify GTE of the
existence and terms of such request or advice, (ii) cooperate with GTE in taking
legally available steps to resist or narrow any such request or to otherwise
eliminate the need for such disclosure at GTE's sole expense, if requested to do
so by GTE, and (iii) if disclosure is required, it shall be the obligation of
GTE to use its best efforts to obtain a protective order or other reliable
assurance that confidential treatment shall be afforded to such portion of the
Confidential Information of GTE as is required to be disclosed.

         10.4. Survival. The obligations set forth in this Section 10 shall
survive any termination, cancellation or expiration of this Agreement or of any
licenses granted pursuant to this Agreement.

the then current annual license fee for such Licensed Software.

         11.2. Termination/Cancellation. Each party shall have the right to
terminate/cancel this Agreement, effective immediately, upon written notice to
the other party, if any of the following events occur:

                  (a) The other files a voluntary petition in bankruptcy (other
         than as creditor);

                  (b) The other is adjudged bankrupt;

                  (c) A court assumes jurisdiction of the assets of the other

         benefit of its creditors except as required in the ordinary course of
         business.

         11.3. Material Breach. Either party may terminate or cancel this
Agreement or any license for Licensed Software, for a material breach or default

         11.5. Effect of Termination or Expiration.

         (a) Upon any expiration, termination or cancellation of this Agreement,
either in its entirety or with respect to any licensed for Licensed Software,
all rights and licenses granted to GENUITY hereunder or related to such Licensed
Software, respectively, shall terminate.

         (b) Within a reasonable time after expiration, termination or
cancellation of this Agreement or of any license for any Licensed Software, but
in no event later than thirty (30) days thereafter, GENUITY shall immediately
cease using the Licensed Software and Confidential Information (or in the

Software, then only such Licensed Software and related Confidential Information)
and shall return to GTE, or shall destroy in a manner satisfactory to GTE, all
forms in whatever medium of such Licensed Software and Confidential Information,
including, without limitation, any and all copies thereof. An officer of GENUITY
shall certify in writing to GTE that GENUITY has complied with the obligations
of this Section 11.5(b).

         (c) No expiration, termination or cancellation of this Agreement, in
whole or in part, shall relieve GENUITY of any obligation to pay amounts due nor
affect any other rights or liabilities of the parties which may have accrued

Agreement, the provisions of Sections 2, 3.2, 3.3, 4, 6, 7.1, 8.4, 9, 10, 11, 12

after the Effective Date and includes in Updates to the Licensed Software, which
Third Party Software has been approved by GENUITY as provided in the IT
Transition Services Agreement, the parties acknowledge and agree that if GTE

balance of any unamortized costs in the event of any termination, cancellation
or non-renewal of the license for the Licensed Software prior to full
amortization of such costs, and upon such payment GENUITY will be entitled to
continue use of such Third Party Software pursuant to the applicable terms and
conditions.

12. Dispute Resolution.

         12.1. General. Any controversy or claim arising out of or relating to
this Agreement, or the breach thereof, shall be settled first, by good faith
efforts of the parties to reach mutual agreement, and second, if mutual
agreement is not reached to resolve the dispute, by final, binding arbitration
as set out in paragraph 6(c) below.

                                       12
<PAGE>

         12.2. Initial Resolution. A party that wishes to initiate the dispute
resolution process shall send written notice to the other party with a summary
of the controversy and a request to initiate these dispute resolution
procedures. Each party shall appoint a knowledgeable, responsible representative
from the company who has the authority to settle the dispute, to meet and
negotiate in good faith to resolve the dispute. The discussions shall be left to
the discretion of the representatives, who may utilize other alternative dispute
resolution procedures such as mediation to assist in the negotiations.
Discussions and correspondence among the representatives for purposes of these
negotiations shall be treated as Confidential Information developed for purposes
of settlement, shall be exempt from discovery and production, and shall not be
admissible in the arbitration described above or in any lawsuit pursuant to Rule
408 of the Federal Rules of Evidence. Documents identified in or provided with
such communications, which are not prepared for purposes of the negotiations,
are not so exempted and may, if otherwise admissible, be admitted in evidence in
the arbitration or lawsuit. The parties agree to pursue resolution under this
subsection for a minimum of 60 days before requesting arbitration.

         12.3. Arbitration. If the dispute is not resolved under the preceding
subsection within 60 days of the initial written notice, either party may demand
arbitration by sending written notice to the other party. The parties shall
promptly submit the dispute to the American Arbitration Association for
resolution by a single neutral arbitrator acceptable to both parties, as
selected under the rules of the American Arbitration Association. The dispute
shall then be administered according to the American Arbitration Association's
Commercial Arbitration Rules, with the following modifications: (i) the
arbitration shall be held in a location mutually acceptable to the parties, and
if the parties do not agree, the location shall be New York City; (ii) the
arbitrator shall be licensed to practice law; (iii) the arbitrator shall conduct
the arbitration as if it were a bench trial and shall use, apply and enforce the
Federal Rules of Evidence and Federal Rules of Civil Procedure; (iv) except for
breaches related to Confidential Information or intellectual property, the
arbitrator shall have no power or authority to make any award that provides for
consequential, punitive or exemplary damages; (v) the arbitrator shall control
the scheduling so that the hearing is completed no later than 60 days after the
date of the demand for arbitration; and (vi) the arbitrator's decision shall be
given within 5 days thereafter in summary form that states the award, without
written decision, which shall follow the plain meaning of this Agreement, the
relevant documents, and the intent of the parties. Judgment on the award
rendered by the arbitrator may be entered in any court having jurisdiction over
the parties. Each party to the dispute shall bear its own expenses arising out
of the arbitration, except that the expenses of the facilities to conduct the
arbitration and the fees of the arbitrator shall be shared equally by the
parties.

         12.4. Injunctive Relief. The foregoing notwithstanding, each party
shall have the right to seek injunctive relief in an applicable court of law or
equity pending resolution of the dispute in accordance with the foregoing.

of all applicable federal, state, and local laws, ordinances, regulations and
codes (including, without limitation, procurement of required permits or

Products are subject to U.S. export and foreign transactions control
regulations. GENUITY undertakes that it shall neither export, nor cause nor
permit to be exported, without GTE's prior written consent and without
compliance with applicable law and regulation, GTE Products or Services out of
the United States of America, nor shall GTE Products or Services be made
available, directly or indirectly, for use in any project associated with the
design, development, production, testing, stockpiling or use of: (i) nuclear
weapons or facilities to produce nuclear explosives, (ii) missiles, or (iii)
chemical or biological warfare agents. GENUITY agrees to comply with all
applicable laws and regulations relating to the exportation of technical
information, as they currently exist and as they may be amended from time to
time.

         13.3. Assignment, Subcontracting. Neither this Agreement nor any rights
or obligations hereunder shall be assignable by either of the parties hereto;
provided, however, that GTE may assign this Agreement to any Affiliate.

         13.4. Waiver of Terms and Conditions. Failure to enforce any of the
terms or conditions of this Agreement shall not constitute a waiver of any such
terms or conditions, or of any other terms or conditions.

         13.5. Severability. Where any provision of this Agreement is declared
invalid, illegal, void or unenforceable, or any changes or modifications are
required by regulatory or judicial action, and any such invalid, illegal, void
or unenforceable provision, or such change or modification, substantially
affects any material obligation of a party hereto, the remaining provisions of
this Agreement shall remain in effect and the parties shall mutually agree upon
a course of action with respect to such invalid provision or such change or
modification to the end that the purposes of this Agreement are carried out.

         13.6. Governing Law. This Agreement, and the rights and obligations
contained in it, shall be governed by and construed in accordance with the laws
of the State of New York, without regard to any conflicts of law principles that
would require the application of the laws of any other jurisdiction.

         13.7. No Unreasonable Delay or Withholding. Where agreement, approval,
acceptance, consent or similar action by GENUITY or GTE is required, such action
shall not be unreasonably delayed or withheld.

         13.8. Force Majeure. If performance of any obligations by either party
under this Agreement (other than any obligation of either party to pay money
hereunder) is prevented, restricted or interfered with by reason of acts of God,
wars, revolution, civil commotion, acts of public enemy, embargo, acts of
government in its sovereign capacity, labor difficulties, including, without
limitation, strikes, slowdowns, picketing or boycotts, communication line
failures, power failures, or any other circumstances beyond the reasonable
control and not involving any fault or negligence of the party affected, the
party affected, upon giving prompt notice to the other party, shall be excused
from such performance on a day-to-day basis during the continuance of such
prevention, restriction or interference (and the other party shall likewise be
excused, on a day-to-day basis during the same period, from performance of its
obligations which are dependent upon or affected by such nonperformance);
provided, however, that the party so affected shall use its best reasonable
efforts to avoid or remove such causes of nonperformance and both parties shall
proceed immediately with the performance of their obligations under this
Agreement whenever such causes are removed or cease.

         13.9. Entire Agreement. This Agreement represents the entire
understanding between the parties with the respect to its provisions and cancels
and supercedes all prior agreements or understandings, whether written or oral,
with respect to the subject matter. This Agreement may only be modified or
amended by an instrument in writing signed by duly authorized representatives of
the parties. This Agreement shall be deemed to include all Schedules issued
