                                    GENUITY

   We are a leading e-business network provider delivering managed Internet
infrastructure services to enterprises and service providers. An e-business
network provider is a facilities-based Internet infrastructure supplier
offering a comprehensive set of managed Internet access, web hosting and value-
added e-business services. The combination of these services allows customers
to purchase integrated e-business solutions. Our comprehensive suite of managed
Internet infrastructure services includes:

  .Internet access through dial-up, dedicated and digital subscriber lines;

  .web hosting and content delivery; and

  . value-added e-business services, such as virtual private networks for
    secure data transmission and security services.

   We operate a state-of-the-art global network that consists of:

  . recently deployed broadband fiber optic cable in the United States;

  . points of presence, which are locations where we provide Internet access
    to end users;

  . secure data centers with redundant fiber connections to our network and
    backup power sources; and

  . undersea and international fiber optic cable capacity.

   Our large base of on-network users and content, combined with our extensive
network, positions us as one of the leading Internet backbone providers in the
world, a status commonly referred to as a Tier 1 Internet backbone provider. An
Internet backbone is an Internet Protocol-based network that connects users and
web content. We believe that service providers are increasingly connecting to
networks with substantial on-network content to improve the quality of their
customers' experience, which in turn drives demand by enterprises seeking to
connect to networks with large numbers of users. We believe that by taking
advantage of this demand cycle, which we call the "network effect", we will
continue to drive significant demand for our services from both enterprises and
service providers and differentiate ourselves from non-Tier 1 Internet backbone
providers. As of March 31, 2000, we provided services to approximately 5,000
enterprises, such as Carrier Corporation, Computer Sciences, CNN, Microsoft,
Sun Microsystems and ZDNet, and to approximately 400 service providers, such as
Akamai Technologies, America Online, Earthlink, NetZero and WebTV in the United
States and I.NET and Tiscali in Italy. Our revenues were approximately $706
million in 1999 and $248 million for the first quarter of 2000, and we incurred
net losses of approximately $647 million in 1999 and $210 million in the first
quarter of 2000.

   Unlike many recent entrants into the Internet industry, we have more than
three decades of experience in designing and implementing the architecture of
the Internet and with solving computer networking problems. In 1969, our
predecessor, BBN Corporation, designed and helped to implement ARPAnet, which
is widely recognized as the basis for the Internet today. Our network is
recognized as the first Internet backbone and, accordingly, was designated AS-
1. We also developed the first Internet router, delivered the world's first e-
mail message and pioneered the use of the "@" symbol as a universal addressing
standard for electronic mail. More recently, we were one of the first to offer
commercial installation, maintenance and support of web sites, which is
referred to as managed web hosting services, and managed security services
through outsourced firewall monitoring.

                                THE OPPORTUNITY

   The Internet has experienced tremendous growth in the past decade and has
emerged as an important global medium for communications and commerce. As the
Internet and data traffic have grown, the cost and complexity for enterprises
and service providers to manage their own network infrastructure demands in-
house has increased. As a result, enterprises and service providers seek to
outsource their infrastructure needs to Internet infrastructure service
providers that can:

  . speed their time-to-market;

  . improve performance, security and the ability to rapidly increase the
    capacity needed to deliver services, which is referred to as scalability;

  . provide continuous operation of their web sites; and

  . reduce the costs and risks associated with developing an in-house
    solution.

   As enterprises and service providers continue to outsource these
requirements, they demand that Internet infrastructure service providers
deliver a high quality Internet experience for their users. We believe leading
Internet infrastructure service providers must offer a comprehensive suite of
managed Internet infrastructure services, a large base of on-network users and
content, reliable and scalable network facilities, Tier 1 Internet connectivity
and the experience and expertise necessary to provide a complete Internet
infrastructure solution.

                                  OUR SOLUTION

   Our e-business network solution enables our customers to outsource their
Internet infrastructure requirements to a single provider and to scale their
Internet operations in a cost-effective and reliable manner. The key elements
of our solution include:

  . Comprehensive Suite of Managed Internet Infrastructure Services. We offer
    a broad range of managed Internet infrastructure services, including:
    Internet access; web hosting and content delivery; and value-added e-
    business services.

  . Large Base of On-Network Users and Content. We carry a significant amount
    of traffic over our Tier 1 Internet backbone, allowing enterprises and
    service providers to directly route traffic to, or receive content from,
    a significant number of other customers without the need to pass through
    other Internet backbones.

  . State-of-the-Art Network. We operate a state-of-the-art, high capacity
    global fiber optic network that is highly reliable and scalable and has
    been equipped with advanced optical electronic equipment. Our network
    includes over 17,500 route miles of fiber optic cable in the United
    States, undersea and international fiber optic cable capacity and 10 data
    centers for web hosting services.


                                       2

  . High Performance, Tier 1 Internet Connectivity. We provide high
    performance connectivity to the Internet through our Tier 1 Internet
    backbone and extensive high speed private connections with other major
    Internet backbone providers.

  . Significant Internet Protocol Engineering and Architectural Expertise.
    Drawing upon the breadth and depth of our IP and networking experience
    and expertise, including over 750 engineers and over 1,100 technicians,
    we are able to quickly and cost-effectively identify the Internet
    infrastructure requirements of our customers and design and implement
    appropriate solutions.

                                  OUR STRATEGY

   Our objective is to be the leading e-business network provider by
architecting, building and operating the infrastructure for the Internet
economy. The principal elements of our strategy for pursuing this objective
include:

  . leveraging the network effect;

  . expanding our capacity and state-of-the-art network;

  . continuing to build and own our network facilities;

  . expanding our distribution capabilities;

  . pursuing strategic transactions and alliances;

  . using our extensive IP and networking expertise to develop new services;
    and

  . establishing Genuity as a leading brand for managed Internet

                         OUR RELATIONSHIP WITH VERIZON

   We are currently a wholly owned subsidiary of GTE. In July 1998, Bell
Atlantic and GTE agreed to enter into a merger of equals transaction. We
anticipate that the merger between Bell Atlantic and GTE will close
concurrently with, or immediately following, the completion of this offering.
In April 2000, Bell Atlantic and GTE announced that following their merger they
will operate under the name Verizon Communications.

   Under the Telecommunications Act of 1996, the Regional Bell Operating
Companies, including the Bell Atlantic local telephone operating companies and
their respective affiliates, are generally prohibited from providing long
distance services that originate in any state in which the Regional Bell
Operating Companies operate an incumbent local telephone company. These
restrictions, which are referred to in this prospectus as Section 271
restrictions, prohibit these companies from offering long distance services
originating in a particular state until the relevant local telephone operating
company operating in that state has satisfied a 14-point competitive checklist
under Section 271 of the Telecommunications Act and obtained authority from the
Federal Communications Commission to provide long distance services in those
states.

   Bell Atlantic operates incumbent local telephone companies in 13 states,
from Maine to Virginia, and the District of Columbia. The total billable access
telephone lines owned by Bell Atlantic in these states in 1999 are referred to
in this prospectus as "Bell Atlantic in-region lines". Bell Atlantic has
obtained the necessary authorization to provide long distance service
originating in New York. Because we provide services in Bell Atlantic's region
that could be characterized as long distance services, Bell Atlantic and GTE
cannot complete their merger until they either:

  .  receive relief from the Section 271 restrictions for the remaining
     states in which Bell Atlantic provides local telephone services; or

  .  implement a structure that complies with the requirements of the
     Telecommunications Act.

   To ensure compliance with the requirements of the Telecommunications Act and
to receive FCC approval of their merger, Bell Atlantic and GTE made a proposal
to the FCC under which GTE would exchange all of the outstanding shares of our
common stock for shares of our Class B common stock and we would make this
offering of our Class A common stock. As a result, immediately after completion
of this offering, the investors purchasing shares in this offering will own
shares of our Class A common stock possessing 90.5% of the total voting power
of our common stock and Verizon will own shares of our Class B common stock
possessing 9.5% of the total voting power of our common stock.

   Our Class B common stock is convertible into Class A common stock or, if
held by Verizon and at its election, Class C common stock. Our Class A common
stock and our Class B common stock have one vote per share and our Class C
common stock has five votes per share. Under the proposal to the FCC, our Class
B common stock cannot be converted into more than 10% of our outstanding common
stock until Verizon has eliminated, as to at least 50% of Bell Atlantic in-
region lines, Section 271 restrictions applicable to its operation of our
business. At such time as Verizon has eliminated the applicable Section 271
restrictions as to at least 50% of Bell Atlantic in-region lines, our
outstanding shares of Class B common stock can be converted by a holder other
than Verizon into 800 million shares of our Class A common stock. This amount
represents approximately 82% of our common stock outstanding after this
offering, or approximately 80% if the underwriters fully exercise their over-
allotment option. At such time as Verizon has eliminated the applicable Section
271 restrictions as to 100% of Bell Atlantic in-region lines, it could convert
its Class B common stock into 800 million shares of Class C common stock,
which, in addition to representing approximately 82% of our common stock
outstanding after this offering, would also possess approximately 96% of the
total voting power of the common stock.

   For more information about the conversion of the Class B common stock, you
should refer to the section in "Description of Capital Stock" entitled
"Conversion of Class B Common Stock".

                            If Verizon does not eliminate the applicable
                            Section 271 restrictions as to at least 50% of Bell
                            Atlantic in-region lines, the Class B common stock
                            is convertible into shares of Class A common stock
                            representing only 10% of our total common stock
                            outstanding.

                            If Verizon eliminates the applicable Section 271
                            restrictions as to at least 50% of Bell Atlantic
                            in-region lines, it would be able to transfer its
                            shares of Class B common stock to one or more third
                            parties that would be able to convert the Class B
                            common stock into an aggregate of 800 million
                            shares of Class A common stock, which immediately
                            after this offering would represent approximately
                            82% of our total equity and voting power.

                            If Verizon eliminates the applicable Section 271
                            restrictions as to 100% of Bell Atlantic in-region
                            lines, it would be able to convert the Class B
                            common stock into 800 million shares of Class C
                            common stock, which immediately after this offering
                            would represent approximately 82% of our total
                            equity and approximately 96% of our total voting
                            power. The following table reflects this

                            Each share of Class A common stock entitles the
                            holder to one vote per share. So long as 50% or
                            more of the shares of Class B common stock
                            outstanding at the completion of this offering
                            remain outstanding, no holder or group of holders
                            of Class A common stock may vote any of their
                            shares in excess of 20% of the aggregate number of
                            the then outstanding number of shares of Class A
                            common stock.

                            Each share of Class B common stock entitles the
                            holder to one vote per share. The holders of the
                            Class B common stock, voting separately as a class,
                            are entitled to elect one of our directors. We are
                            also required to obtain the consent of the holders
                            of Class B common stock before taking specific
                            actions, including making significant acquisitions
                            or dispositions, entering into major business
                            combinations and incurring indebtedness or issuing
                            additional equity securities in excess of specified
                            limits. You should refer to the section in "Related
                            Party Transactions" entitled "Recapitalization
                            Agreement" and the section in "Description of
                            Capital Stock" entitled "Common Stock" for a more
                            detailed description of these consent requirements,
                            including the circumstances under which these
                            consent requirements may be transferred and when
                            they terminate.

                            Each share of Class C common stock entitles the
                            holder to five votes per share.

Conversion of Class B
 Common Stock........       Immediately after the completion of this offering,
                            Verizon will own all of the outstanding shares of
                            our Class B common stock. Although the ability of
                            Verizon to convert its shares of our Class B common
                            stock is limited by the proposal to the FCC, these
                            shares by their terms are convertible at any time
                            into either:

                            .  shares of Class A common stock equal to 10% of
                               our total common stock immediately after the
                               conversion; or

                            .  800 million shares of Class A common stock or,
                               for Verizon or any of its affiliates and at
                               their election, Class C common stock, which
                               represent approximately 82%, or approximately
                               80% if the underwriters exercise in full the
                               over-allotment option, of our shares of common
                               stock outstanding immediately following this
                               offering.

                            Under the proposal to the FCC:

                            .  if Verizon has not eliminated Section 271
                               restrictions applicable to its operation of our
                               business as to at least 50% of Bell Atlantic in-
                               region lines, Verizon can only convert its
                               outstanding shares of our Class B common stock
                               into shares of our Class A common stock that
                               after the conversion will represent 10% of our
                               total common stock then outstanding. If Verizon
                               transfers the Class B common stock before
                               meeting this 50% threshold, the transferee's
                               conversion rights would be similarly limited;

                            .  if Verizon has eliminated the applicable Section
                               271 restrictions as to at least 50% of Bell
                               Atlantic in-region lines, it could transfer its
                               shares of Class B common stock to one or more
                               third parties who would then be able to convert
                               them in the aggregate into 800 million shares of
                               Class A common stock; and

                            .  if Verizon has eliminated the applicable Section

                               region lines, Verizon or its affiliates could
                               convert the Class B common stock into 800
                               million shares of Class A common stock or Class
                               C common stock.

                            Under the proposal to the FCC, if Verizon has not
                            eliminated the applicable Section 271 restrictions
                            as to 100% of Bell Atlantic in-region lines on or
                            before    , 2005, which date may be extended under
                            conditions that we describe in the section in
                            "Description of Capital Stock" entitled "Conversion
                            of Class B Common Stock", Verizon's ability to
                            convert the Class B common stock into 800 million
                            shares of Class A common stock or Class C common
                            stock will expire. Verizon will continue to retain
                            its right to convert its shares of our Class B
                            common stock into shares of Class A common stock
                            representing 10% of our total common stock then
                            outstanding. If Verizon has satisfied the
                            applicable Section 271 restrictions as to 100% of
                            Bell Atlantic in-region lines on or before that
                            date, its ability to convert the Class B common
                            stock into 800 million shares of Class A common
                            stock or Class C common stock will not expire. The
                            Class B common stock transferred by Verizon to a
                            third party will not be subject to the expiration
                            limitation.

Conversion of Class C
  Common Stock.......       Our Class C common stock is convertible into Class
                            A common stock at any time. Each share of Class C
                            common stock will automatically convert into one
                            share of Class A common stock if at any time the
                            aggregate number of outstanding shares of Class C
                            common stock, together with any shares of Class C
                            common stock issuable upon conversion of Class B
                            common stock, constitute less than 10% of our then
                            outstanding common stock.

Transfer of Class C
  Common Stock.......       Verizon can transfer shares of our Class C common
                            stock at any time. Any shares of our Class C common
                            stock so transferred will automatically convert
                            into shares of our Class A common stock on the
                            earlier to occur of (1) any subsequent transfer of
                            ownership of such shares or (2) the first
                            anniversary of the transfer of such shares by
                            Verizon. Accordingly, persons other than Verizon
                            could own shares of our Class C common stock.

                        SUMMARY COMBINED FINANCIAL DATA

   The following tables present our summary combined financial data. The
financial data presented in these tables are from "Selected Combined Financial
Data" and our combined financial statements and accompanying notes included
elsewhere in this prospectus. You should read those sections for a further
explanation of the financial data summarized here.

   Our combined financial statements have been carved out from the consolidated
financial statements of GTE using the historical results of operations and
historical bases of the assets and liabilities of Genuity. Accordingly, the
historical financial information we have included in this prospectus does not
necessarily reflect what our financial position, results of operations and cash
flows would have been had we been a separate, stand-alone entity during the
periods presented.

                                  RISK FACTORS

   Investing in our Class A common stock involves a high degree of risk. You
should carefully consider the following factors, as well as other information
contained in this prospectus, before deciding to invest in shares of our Class
A common stock. If any of the following risks actually occurs, our business,
financial condition and results of operations could suffer, in which case the
trading price of our Class A common stock could decline and you may lose all or
part of your investment.

Risks Related to Our Business

   We have a history of significant operating losses and expect these losses to
continue for at least the next several years.

   We have experienced operating losses in each quarterly and annual period
since 1996. Given the level of our planned operating and capital expenditures,
we expect to continue to incur significant operating losses for at least the
next several years. We incurred operating losses of approximately $464 million
in 1998, approximately $645 million in 1999 and $198 million in the first
quarter of 2000. As of March 31, 2000, we had an accumulated deficit of
approximately $1.5 billion.

   We plan to continue to make significant investments to expand our capacity
and network infrastructure, develop brand recognition, broaden the range of our
service offerings and expand our sales, marketing, technical and customer
support personnel. Our capital expenditures program, as currently contemplated,
will require between $11 billion and $13 billion during the five-year period
ending December 31, 2004, the majority of which will be for the expansion of
our network infrastructure. A substantial portion of these expenditures will be
made long before any significant revenue related to these expenditures may be
realized.

   In addition, our operating expenses are based largely on anticipated revenue
trends and a significant portion of our expenses, such as personnel, the leased
portion of our network and our real estate facilities and depreciation of our
network infrastructure, is fixed. If our revenues fall below our expectations,
we would probably not be able to reduce our fixed or variable expenses in
sufficient time to respond to the shortfall. If we fail to achieve significant
increases in our revenues as a result of our investments, the size of our
operating losses may be larger than expected. We may never achieve
profitability or generate positive cash flows from operations, and if we do
achieve profitability or positive cash flows from operations in any period, we
may not be able to sustain or increase profitability or positive cash flows on
a quarterly or annual basis.

   If we do not maintain or increase our market share and therefore are no
longer considered a Tier 1 Internet backbone provider, we may lose customers
and our free peering relationships with other Tier 1 Internet backbone
providers. If this occurs, our revenues and operating results may decline
significantly.

   We rely significantly on our status as a Tier 1 Internet backbone provider
to maintain and grow our market share and compete with other Tier 1 Internet
backbone providers, several of which have a larger market share than we do. Any
significant loss of market share for our services could cause the loss of our
status as a Tier 1 Internet backbone provider, which would make our services
significantly less attractive to existing and potential customers and would
likely result in a significant loss of revenues. In addition, the loss of
market share or our status as a Tier 1 Internet backbone provider would
adversely affect our ability to maintain our free private peering relationships
with other Tier 1 Internet backbone providers. Currently, these relationships
permit us to have direct, cost-free exchange of traffic with other Tier 1
Internet backbone providers and allow us to avoid the congestion of public
peering points when directing traffic to users connected to those other
Internet backbones. If we are unable to maintain these free peering
relationships, our operating costs will increase and our results of operations
will suffer.

                                       10
<PAGE>

   To increase or at least maintain our market share and maintain our status as
a Tier 1 Internet backbone provider, it is critical that a significant amount
of worldwide Internet traffic be carried on our Internet backbone. To generate
significant Internet traffic, we must:

  .  continue to increase the amount of content available on our network
     infrastructure by successfully marketing our web hosting and high speed
     dedicated Internet access services to enterprises, particularly
     enterprises that operate high traffic web sites; and

  .  continue to increase the number of users that access the Internet
     through our Internet backbone by successfully marketing our Internet
     access services to service providers.

   We may not be successful in marketing our services to enterprises and
service providers if we fail to expand our capacity and network infrastructure
to meet increasing demand or to competitively price or expand our services or
if we experience network performance and reliability problems.

   If we were to lose a significant portion of our revenues from America
Online, we would not be able to replace those revenues in the short term and
our operating losses would increase significantly.

   The termination of, or a significant adverse change in, our relationship
with America Online would have a material adverse effect on our revenues.
America Online accounted for approximately 53% of our revenues in 1998, 52% of
our revenues in 1999 and 46% of our revenues in the first quarter of 2000. We
expect that revenues from America Online will continue to represent a
significant portion of our revenues for the next several years. America Online
has the right to terminate its agreement with us on 30 days notice if we
materially breach the agreement, including our failure to meet specific
performance targets, and fail to cure the breach within that notice period.
America Online also has the right to terminate its agreement with us
immediately without notice if we commit repeated material breaches of the
agreement or if we violate the terms of a few specific material provisions
under the agreement. America Online also has the right to reduce its purchase
commitments if we, among other things, fail to meet specific delivery and
performance targets or fail to meet our obligation to provide most favored
customer pricing. In addition, upon a change in control of Genuity, America
Online has the right to terminate the agreement. A transfer of Verizon's
interest in Genuity to an unrelated party may constitute a change in control of
us. You should refer to the section in "Business" entitled "Our Relationship
With America Online" for additional information about our relationship with
America Online.

   If we cannot obtain the additional capital we will require to fund our
operations and finance the expansion of our capacity and network
infrastructure, we will have to delay or abandon our development and expansion
plans.

   We will need significant additional capital to fund our business plan and
achieve profitability. We currently intend to spend $11 billion to $13 billion
over the five-year period ending December 31, 2004, of which approximately $1.8
billion to $2.0 billion is expected to be spent during 2000, on the continued
expansion of our network infrastructure and other capital expenditures. During
the past three years, our capital needs have been satisfied with permanent
capital contributions from GTE or financing from its affiliates. However,
following this offering, Verizon is not obligated to provide funds to finance
our capital expenditures, working capital or other cash requirements. Under the
proposal to the FCC, Verizon is not permitted, before the conversion of its
shares of our Class B common stock, to provide more than 25% of the debt
financing that we are permitted to incur under the Recapitalization Agreement.
We may be unsuccessful in raising sufficient capital on terms that we consider
acceptable, when needed or at all. If this happens, we would have to delay or
abandon our development and expansion plans, which would adversely affect our
competitive position.

   We currently intend to obtain additional capital through public offerings or
private placements of debt or equity securities or through borrowings under
future credit facilities. However, we are required to obtain the consent of the
holders of our Class B common stock before issuing any shares of our capital
stock in excess of specified amounts and our agreement with Verizon limits our
ability to incur debt in excess of specified

                                       11
<PAGE>


amounts without its consent. You should refer to the risks described below
under "Risks Related to Our Relationship with Verizon", the section in "Related
Party Transactions" entitled "Recapitalization Agreement" and the section
entitled "Description of Capital Stock" for more detailed discussions of the
rights of our Class B common stock.

   If we do not compete effectively, particularly against established
participants with greater financial and other resources than ours, we will lose
market share, which will make our services less attractive to our existing and
prospective customers.

   The market for managed Internet infrastructure services is extremely
competitive and subject to rapid change. We expect to encounter increased
competition in the future as a result of increased consolidation and strategic
alliances in the industry. In addition, we will increasingly compete with
foreign service providers as we expand internationally and as these service
providers increasingly compete in the United States. If we are unable to
compete successfully, we would experience a loss in customers and the revenues
that accompany that business.

   Our principal competitors in the managed Internet infrastructure services
market include:

  . Internet infrastructure service providers such as UUNET Technologies, a
    subsidiary of MCI WorldCom, AT&T, Sprint and Cable & Wireless, each of
    which offers similar services and possesses the network scale and on-
    network users and content to offer their customers connectivity to
    virtually all addresses on the Internet, either directly through their
    Internet backbone or through cost-free, high speed private peering
    relationships;

  . Internet service providers that have a significant regional, national or
    international presence but do not offer as broad a range of services or
    possess fewer users and less on-network content, such as Level 3
    Communications, Qwest Communications, KPNQwest, Deutsche Telekom, PSINet
    and Verio Communications; and

  . companies that service generally only one or a few specific Internet
    infrastructure needs of enterprise customers, including web hosting
    companies such as Digex and Exodus Communications; broadband access
    providers, such as Covad Communications and Rhythms NetConnections;
    providers of security and virtual private networks, such as Pilot Network
    Services; and transport service providers, such as Level 3
    Communications, Qwest Communications and Williams Communications Group.

   Numerous other companies from a variety of industries have also focused on
our target market. For example, many of the major cable companies have begun
offering, or are exploring the possibility of offering, Internet access by
engineering their current networks to include Internet access capabilities.
Direct broadcast satellite and wireless communications providers have also
entered the Internet access market with various wireless and satellite-based
service technologies. We have no patented technology that would preclude or
inhibit competitors from entering our market.

   Many of these existing competitors have and potential competitors may have
greater financial and other resources, more customers, a larger installed
network infrastructure, greater market recognition and more established
relationships and alliances in the industry. As a result, these competitors may
be able to develop and expand their network infrastructure and service
offerings more quickly, adapt more swiftly to new or emerging technologies and
changes in customer demands, devote greater resources to the marketing and sale
of their offerings, pursue acquisitions and other opportunities more readily
and adopt more aggressive pricing policies. UUNET has substantially greater
market share and resources than we do. In addition, MCI WorldCom and Sprint
have announced a proposed merger. We believe this proposed merger would
substantially increase the market share and competitive position of UUNET, even
if it were required to divest itself of portions of its Internet backbone as a
condition of the merger. Some of our competitors are able to bundle their
Internet service offerings with other complementary services, such as local and
long distance voice, data transmission and video services, thereby reducing the
overall cost of their services compared with ours. We may not be able to offset
the effects of any of these actions.

                                       12
<PAGE>

   We expect that the rates we charge for our services will decline over time,
and we may not be successful in reducing our operating expenses or introducing
new services that will compensate for these lost revenues.

   We expect to continue to experience decreasing prices for our services as we
and our competitors increase transmission capacity on existing and new
networks, as a result of our current agreements with customers, through
technological advances or otherwise, and as volume-based pricing becomes more
prevalent. For example, at specified times during the course of our agreement
with America Online, America Online has the right to seek a reduction in the
fees paid to us for access ports and digital subscriber line and other
broadband services. Accordingly, our historical revenues are not indicative of
future revenues based on comparable traffic volumes. If the prices for our
services decrease for whatever reason and we are unable to offer additional
services from which we can derive additional revenues or otherwise reduce our
operating expenses, our operating results will decline and our business and
financial results will suffer.

   Our strategy contemplates future international expansion but there are
significant operational and financial risks associated with international
operations.

   Although we have not derived significant revenues from our international
operations in the past, an important component of our strategy is to expand
significantly our presence in international markets. As we expand, we will
substantially increase our exposure to the risks inherent in international
operations, including, among others, the following:

  . general economic, social and political conditions;

  . unexpected changes in legal or regulatory requirements resulting in
    unanticipated costs and delays;

  . differences in technology standards;

  . tariffs, export and exchange controls and other trade barriers;

  . fluctuations in foreign currency exchange rates;

  . difficulty of enforcing agreements and collecting accounts receivables;

  . adverse tax consequences;

  . changes in United States laws and regulations relating to foreign trade
    and investment; and

  . inability to offer some services in some countries due to regulatory and
    other barriers.

   You should refer to the section in "Business" entitled "Our International
Operations" for additional information about our existing and planned
operations in international markets.

   Further, to expand our international operations, we may enter into joint
ventures or outsourcing agreements with third parties, acquire rights to high
bandwidth transmission capability, acquire complementary businesses or
operations or establish and maintain new operations outside the United States.
We may be heavily dependent on third parties to be successful in our
international operations. We may not be able to successfully sell our services
or adequately establish or maintain operations outside the United States.

   If we are unable to manage our planned expansion effectively, we may incur
increased costs, experience capacity constraints and place too many demands
upon our management team.

   We are currently experiencing a period of rapid expansion and, if our
business plan is successfully implemented, we expect our expansion to continue
for the foreseeable future. This expansion will increase our operating
complexity significantly and require significant time commitments from our
management team and severely restrict their ability to manage our existing
business. Our failure to manage our expansion effectively could increase our
costs, adversely affect our relations with customers and suppliers, result in
insufficient capacity over extended periods of time and adversely affect our
revenues and operating margins. Accordingly,

                                       13
<PAGE>


our success depends on our ability to effectively manage this expansion and the
demands it will impose on our management. In addition to training and managing
an increasing number of highly skilled employees, we will need to successfully
expand our capacity and network infrastructure and continually enhance our
information, management and operational and financial systems.

   If we are not successful in achieving brand recognition for the Genuity
name, our competitive position will be weakened and we could lose market share.

   We believe that establishing, maintaining and continually strengthening our
brand in domestic and international markets is a critical aspect of our efforts
to expand our customer base, solidify business relationships and successfully
implement our business strategy. The growing number of companies that offer
competing Internet infrastructure services increases the importance of
establishing and strengthening brand recognition. However, we only recently
changed our name to Genuity. Because our brand is new, it currently has very
limited recognition in the market. Our brand may not be viewed positively or be
accepted by the market. We intend to incur significant expenses to promote our
brand. The expenses we incur toward building our brand, however, may not result
in immediate returns and it may be a long time before enterprises, service
providers and business partners recognize and make positive connections with
our brand. In addition, our brand may be diluted if customers do not perceive
our services to be of high quality or if we fail to provide a satisfactory
customer service experience. We may not be successful in achieving these goals.

   Our ability to develop, market and support our managed Internet
infrastructure services depends on retaining our management team and attracting
and retaining highly qualified individuals in the Internet industry.

   Our future success depends to a significant extent on the continued services
of our management team. Our management team, which is described in the section
entitled "Management", has significant experience with data communications,
telecommunications and managed Internet infrastructure services, as well as
relationships with many of the enterprises, service providers and business
partners that we currently or may in the future rely on in implementing our
business plan. The loss of the services of our management team or any
significant portion of it could have a substantial detrimental effect on our
ability to execute our business strategy.


   Our future success also depends on our continuing ability to identify, hire,
train, assimilate and retain large numbers of highly qualified technical,
sales, marketing and managerial personnel. The demand for qualified personnel
is high and competition for their services is intense. The competition for
qualified employees in the Internet industry is particularly intense in the
Boston, Massachusetts area where our principal operations are located. We have
from time to time experienced, and we expect to continue to experience in the
future, difficulty in hiring and retaining highly skilled employees with
appropriate qualifications. If we do not succeed in attracting new personnel or
retaining our current personnel, our business will suffer.

   Our historical financial information may not be representative of our
results of operations as a separate entity.

   The historical financial information we have included in this prospectus
does not necessarily reflect what our financial position, results of operations
and cash flows would have been had we been a separate, stand-alone entity
during the periods presented. GTE did not account for us, and we were not
operated, as a separate, stand-alone entity for the periods presented. Our
combined financial statements have been carved out from the consolidated
financial statements of GTE using the historical results of operations and
historical bases of the assets and liabilities of our business. Our costs and
expenses include allocations from GTE for centralized corporate services and
infrastructure costs, including legal, accounting, treasury, real estate,
information technology, distribution, customer service, sales, marketing and
engineering. These allocations have been determined on bases that we and GTE
considered to be reasonable reflections of the utilization of services provided
to or the benefit received by us. We have not made adjustments to our
historical financial information to reflect many significant changes that will
occur in our cost structure, funding and operations as a result of our
operating as a stand-alone company, including increased costs associated with
reduced economies of scale,

                                       14
<PAGE>


increased marketing expenses related to building brand identity separate from
GTE and increased costs associated with being a publicly traded, stand-alone
company. Any increase in our costs related to these or similar factors could
adversely affect our operating results in future periods, which could cause the
market price of our Class A common stock to decline.

   If we do not respond effectively and on a timely basis to rapid
technological changes, our services may become obsolete and we would probably
lose customers and be unable to attract new ones.

   The managed Internet infrastructure services industry is characterized by
rapid technological developments and frequent new product and service
introductions and enhancements. The introduction of new products or
technologies could render our network or service offerings obsolete, thereby
requiring us to spend more than we currently anticipate in future periods in
order to remain competitive and retain our existing customers and attract new
ones. Similarly, technological developments could reduce the cost or increase
the supply of services similar to those that we provide or plan to provide,
which could result in lower than expected revenues in future periods. We may
not be able to:

  . anticipate or adapt to these new products or technologies on a timely and
    cost-effective basis;

  . obtain the necessary funds to develop or acquire new technologies or
    products needed to compete; or

  . address the increasingly sophisticated and varied needs of our current
    and prospective customers.

   Our ability to compete could be jeopardized if our network and services do
not properly operate with the existing or future equipment of our customers.

   We believe that our ability to compete successfully is dependent upon the
continued compatibility of our network and service offerings with products,
services and architectures offered by others, particularly our enterprise and
service provider customers. Although we often work with vendors in testing
newly developed products, these products may not be compatible with our
infrastructure. In addition, although we currently intend to support emerging
standards, there can be no assurance industry standards will be established or,
if they become established, that we will be able to conform to these new
standards in a timely fashion and maintain a competitive position in the
market. Our competitive position would be adversely affected if we fail to
conform to the prevailing standards, or if common standards fail to emerge.

   We may lose customers if we experience system failures that significantly
disrupt the availability and quality of the services that we provide.

   Our operations depend on our ability to avoid and mitigate any damages,
physical or otherwise, from natural disasters, power losses, capacity
limitations, physical or electronic breaches of security, software defects,
telecommunications failures and intentional acts of vandalism, including
computer viruses. The failure of any equipment or facility on our network could
result in interruptions in service or reduced capacity for our enterprise and
service provider customers until we make the necessary repairs or install
replacement equipment. In addition, our customers may experience interruptions
in service if carriers or other service providers fail to provide the
communications capacity that we have leased in order to provide service to our
customers or if our peering arrangements suffer significant disruption. For
example, in 1999 a third party provider from whom we lease capacity experienced
a significant disruption. Further, a majority of our traffic is transmitted
over capacity that we lease from third parties. The failure of any one of these
connections also could result in reduced performance.

   These interruptions in service or performance problems could undermine
confidence in our services and cause us to lose customers or make it more
difficult to attract new ones. For example, America Online has the right to
reduce its purchase commitments and terminate its agreement with us if we fail
to meet agreed upon performance levels. In addition, because many of our
services are critical to the businesses of many of our customers, any
significant interruption in our service could result in lost profits or other
loss to our customers. Although we attempt to disclaim liability in our service
agreements, a court might not enforce a limitation on

                                       15
<PAGE>

our liability, which could expose us to financial loss. In addition, we often
provide our customers with guaranteed service level commitments. If we do not
meet the required service levels as a result of service interruptions, we may
be obligated to provide credits, generally in the form of free service for a
short period of time, to our customers, which could significantly reduce our
revenues.

   If we do not safeguard the security and privacy of our network
infrastructure, our reputation could be damaged and we could lose existing and
prospective customers and the potential revenues they represent.

   The secure transmission of confidential information over networks, including
our network, is critical to the acceptance of the Internet. Internet usage
could decline if any well-publicized compromise of security occurs. Our
customers often maintain confidential information on our servers, such as
credit card and bank account numbers. We provide managed security services that
are intended to provide a high level of protection for our customers' networks.
Our managed security services include monitoring the network perimeters of our
enterprise customers and using firewall management, maintenance and proactive
response techniques to help ensure the security of access points into our
customers' computing infrastructure. We rely on encryption and authentication
technology to provide secure transmission of confidential information.

   Despite our efforts, we may not be successful in maintaining information as
confidential or adequately safeguarding our customers' networks. Someone who is
able to circumvent our security measures could misappropriate proprietary
information or cause disruptions in our operations and those of our customers.
Any compromise of security in our network could damage our reputation and cause
us to lose existing and prospective customers. We may be required to expend
significant capital and other resources to protect against, or to alleviate
problems caused by, security breaches. In addition, a compromise of security
may result in claims against us, which could be successful. These claims,
regardless of their ultimate outcome, could result in costly litigation and
adversely affect our ability to attract and retain customers.

   We rely on limited sources for supplying critical components of our network
infrastructure. If we are unable to obtain sufficient quantities of critical
equipment from these sources when needed, we may be forced to delay our
development and expansion plans, which would negatively affect our competitive
position.

   We depend on vendors to supply the critical components of our network
infrastructure as we expand our network both domestically and internationally.
If we are unable to obtain these critical components on a timely basis, we may
have to abandon or delay our expansion plans, which would adversely affect our
competitive position. Some of our networking equipment is available only from
one or a small number of sources. For instance, we rely on Cisco Systems for
our network routers and Nortel Networks for our optical electronic equipment.
We typically purchase or lease all of our components under purchase orders
placed from time to time. We do not carry significant inventories of components
and have no guaranteed supply arrangements with vendors. Our vendors also sell
products to our competitors and we cannot assure you that they will not enter
into exclusive arrangements with our competitors.

   We need to obtain additional capacity for our network from other providers
in order to serve our customers and keep our costs down.

   We lease telecommunications capacity and obtain rights to unused fiber optic
strands from both long distance and local telecommunications carriers in order
to extend the range of our network. Our inability to obtain this additional
capacity on acceptable terms, or at all, could adversely affect our ability to
quickly expand our network, attract new customers and serve our existing
customers or could increase our costs of doing so.

   We must obtain permits and rights-of-way to develop our network
infrastructure. If we do not obtain them in a timely fashion, we may have to
delay our expansion plans.

   The expansion of our network infrastructure will require that we obtain
licenses, permits and other rights, including rights-of-way and encroachment
agreements and other permits to install conduit and related network

                                       16
<PAGE>

equipment, from private landowners, utilities, railroads, local exchange
carriers, state highway authorities, local governments and transit authorities.
The process of obtaining these licenses, permits and rights can be time
consuming and burdensome. In addition, if we are unable to obtain these
licenses and permits on acceptable terms and on a timely basis, our ability to
expand and operate our network would be severely limited and our business will
not grow as we have planned.

Risks Related to Our Relationship With Verizon

   Verizon's interests as a minority investor and potential future majority
stockholder of Genuity will be protected by the investor safeguards described
below. Under these safeguards, we need the consent of Verizon before taking the
actions described below. Verizon is not required to grant its consent and may
have interests that are different from ours.

   We are contractually obligated to obtain the consent of Verizon before we
take any of the following actions:

  .  making any acquisition or series of related acquisitions with a purchase
     price of more than 20% of our market capitalization at that time;

  .  making an acquisition in excess of $100 million or entering into a joint
     venture in which our investment is more than $100 million, in each case
     that is not closely related to our business;

  .  making any disposition or series of related dispositions for
     consideration, including any indebtedness assumed, of more than 20% of
     our market capitalization at the time;

  .  incurring indebtedness in any calendar year of more than $3.85 billion,
     net of any repayments made during the year, or incurring any
     indebtedness that would cause our aggregate indebtedness to exceed $11
     billion;

  .  entering into any agreement with provisions that trigger a default or
     require a material payment when Verizon converts its Class B common
     stock or that purports to bind Verizon or any of its affiliates; and


  .  issuing any equity securities, although there are significant exceptions
     for issuances in connection with acquisitions, employee benefit plans
     and operating needs and capital expenditures.

   You should refer to the section in "Related Party Transactions" entitled
"Recapitalization Agreement" for a more detailed description of these
contractual restrictions.

   In addition, our certificate of incorporation requires us to obtain the
approval of the holders of a majority our Class B common stock before we:

  .  amend our certificate of incorporation, or amend our bylaws in a way
     that affects the rights of the holders of the Class B common stock;

  .  agree to enter into a merger, consolidation or sale, lease or other
     disposition of all or substantially all of our assets;

  .  file or declare bankruptcy or liquidation;

  . authorize additional shares of our capital stock;

  .  materially change the nature or scope of our business; or

  .  take any action that would make it unlawful for a holder of Class B
     common stock to exercise its conversion rights.

                                       17
<PAGE>


   Verizon could prevent us from taking the actions described above. Verizon's
interests and objectives, which may diverge from ours, may influence whether
Verizon is willing to grant us any consents we may request. We may not be able
to resolve potential conflicts between Verizon and us to our satisfaction, and
if we cannot, our business may be harmed. The ability of Verizon to prevent us
from taking these actions will terminate under the circumstances described in
"Related Party Transactions" in the section entitled "Recapitalization
Agreement" and in "Description of Capital Stock" in the section entitled
"Common Stock".

   Verizon has the right to transfer some or all of its shares of Class B
common stock to one or more persons. Verizon also may assign its contractual
rights to transferees of the Class B common stock. In that event, these persons
would be able to prevent us from taking the actions described above.

   If Verizon is able to convert its shares of our Class B common stock into
shares of our Class C common stock, it will have the ability to exert
significant control over our business.

   Although upon completion of this offering Verizon will hold shares of our
Class B common stock that represent 9.5% of our outstanding common stock at
that time, under the terms of the proposal to the FCC, if Verizon is permitted
to own more than 10% of our outstanding shares of common stock, it could
convert its shares into 800 million shares of Class C common stock. Based on
the shares of common stock outstanding immediately after this offering, these
shares would possess approximately 96% of the total voting power of our common
stock. After conversion of its shares of our Class B common stock, if Verizon
continues to beneficially own shares of capital stock representing more than
50% of the voting power of our outstanding capital stock, Verizon will be able
to exercise a controlling influence over us, including with respect to the
election of our directors and the outcome of any corporate transaction or other
matter submitted to our stockholders for approval. The voting power of Verizon
could have the effect of delaying or preventing a change in control. The
interests of Verizon may differ from the interests of our other stockholders.

   Even if Verizon does not eliminate the applicable Section 271 restrictions
on all of Bell Atlantic in-region lines, it could still transfer a controlling
interest to someone who could exert significant control over our business.

   Verizon may transfer some or all of its shares of Class B common stock
without our consent or the consent of the holders of our Class A common stock.
If Verizon transfers all of the Class B common stock after it has eliminated
the applicable Section 271 restrictions as to at least 50% of Bell Atlantic in-
region lines, the transferee would be able to convert those shares into 800
million shares of our Class A common stock and exercise significant control
over our business. Even if Verizon transfers fewer than all of its shares of
Class B common stock, the transferee might be able to exercise a controlling
influence over us after converting its shares of Class B common stock. In
addition, Verizon could convert its shares of our Class B common stock into
Class C common stock and transfer those shares to one or more persons who could
then exercise a controlling influence over us.

   We have contracted with Verizon to provide us with a variety of transitional
services for a limited period of time. We may experience transitional problems
if we are unable to replace these services in a timely manner or on similar
terms.

   We have not been operating as a stand-alone company. Affiliates of Verizon
are contractually obligated to provide us with office and operating facilities
and specified transitional services upon completion of this offering. If
Verizon does not perform its contractual obligations under these agreements, we
may not receive these services at the same level or obtain the same benefits as
when we were part of GTE. The agreements for those transitional services
generally terminate one year after this offering. After the termination of
these various arrangements, we may not be able to replace these transitional
services or enter into appropriate leases in a timely manner or on terms and
conditions, including cost, similar to those we will receive from Verizon or
are otherwise acceptable to us. You should refer to the section entitled
"Related Party Transactions" for more information about these arrangements.

                                       18

Risks Related to Legal Uncertainty

   Our competitive position would be harmed if we are unable to protect our
intellectual property rights.

   Despite the precautions we take to protect our intellectual property, it may
be possible for a third party to copy or otherwise misappropriate and use our
technology without authorization, particularly in foreign countries where the
laws may not protect our proprietary rights to the same extent as do the laws
of the United States, or for our competitors to develop substantially
equivalent or superior technology independently. If competitors are able to use
our proprietary technology or develop similar technology, our ability to
compete effectively would be seriously harmed. We may need to resort to
litigation in the future to enforce our intellectual property rights, to
protect our trade secrets or to determine the validity and scope of the
proprietary rights of others. This litigation could result in substantial costs
and diversion of resources.

   We may be subject to infringement claims that could subject us to
significant liability or otherwise adversely affect our operating results.

   We expect that participants in our markets will be increasingly subject to
infringement claims. Third parties may try to claim our services infringe their
intellectual property. Any claim, whether meritorious or not, could be time
consuming, result in costly litigation or require us to enter into royalty or
licensing agreements. These royalty or licensing agreements might not be
available on terms acceptable to us or at all, in which case we would have to
cease selling, incorporating or using those services that incorporate the
challenged intellectual property and expend substantial amounts of resources to
redesign our services. If we are forced to enter into unacceptable royalty or
licensing agreements or to redesign our services, our business and prospects
would suffer.

   Some of the services we provide may in the future be regulated by the FCC,
states or foreign governments, which would significantly increase our operating
complexity and expenses and adversely affect our ability to compete.

   Our existing and planned managed Internet infrastructure services are
currently classified as "information services" and, therefore, are exempt from
regulation by the FCC or any other government agency of the United States,
except to the extent that any regulations apply to businesses generally.
However, the regulatory characterization of Internet infrastructure services is
currently unsettled, and some private parties and regulators have raised
questions about the current regulatory status of Internet service offerings. As
a result, the FCC may choose to impose a new set of regulations on Internet
infrastructure services or reclassify them as either private carrier services
or telecommunications services. If existing telecommunications regulations are
extended to the Internet, or if new regulations are imposed, we may be
restricted in the way we offer our services, our cost of doing business could
increase and we could be required to exit some or all of our businesses. You
should refer to the section in "Business" entitled "Regulatory Matters" for a
more detailed description of the federal, state and international regulations
that could apply to our business if any of our services were reclassified as
either private carrier services or telecommunications services.

   Although we believe that any regulation that applies to our business will
likewise apply to our competitors offering similar services, some of our
competitors are already regulated as telecommunications carriers due to their
other service offerings. As a result, these companies may be better able to
operate in a regulated environment than we are. Accordingly, regulatory changes
of the type described above could adversely affect our ability to compete
effectively against these competitors. There is no way to predict the future
regulatory framework of our industry.

   The regulation of the Internet is unsettled and future regulations could
adversely affect our operating costs and business.

   In addition to potential regulation of the Internet and related services by
the FCC and actual regulation of the operations of one of our subsidiaries, our
business may be adversely affected by the adoption of other laws

                                       19
<PAGE>


and regulations in the United States or abroad that apply generally to
commerce and communication over the Internet, including laws or regulations
relating to intellectual property, telecommunications, privacy, consumer
protection, taxation and dissemination of unlawful or otherwise disfavored
content. The adoption or consideration of additional legislation or regulation
affecting the Internet could inhibit the continued growth of the Internet or
decrease its acceptance as a commercial medium, impose additional operating
and other costs on us, expose us to greater potential liability from
regulatory actions or private legal proceedings or otherwise adversely affect
our business operations or performance. We cannot predict the impact, if any,
that future laws and regulations relating to the Internet or legal or
regulatory changes may have on our business. You should refer to the section
in "Business" entitled "Regulatory Matters--Other Potential Regulation" for a
more detailed discussion of existing and potential laws and regulations that
could affect our business.

   We may be subject to regulation, taxation, enforcement or other liabilities
in unexpected jurisdictions.

   We provide our managed Internet infrastructure services to customers
located throughout the United States and internationally. As a result, we may
be required to qualify to do business, or be subject to tax or other laws and
regulations, in these jurisdictions even if we do not have a physical presence
or employees or property in these jurisdictions. The application of these
multiple sets of laws and regulations is uncertain, but we could become
subject to regulation, taxation, enforcement or other liability in unexpected
ways, which could materially adversely affect our business, financial
condition and results of operations.

   If Verizon is unable to convert its Class B common stock to Class C common
stock, we will not be able to realize the benefits of being a majority-owned
subsidiary of Verizon.

   If Verizon is unable to convert its Class B common stock into Class C
common stock, we may not realize the full benefits of our relationship with
Verizon. These benefits include the ability to:

  . offer combined packages of Internet infrastructure services and telephony
    services;

  . obtain financing on more favorable terms than we otherwise could;

  . integrate network infrastructure and reduce overhead costs; and

  . take further advantage of the purchasing power of Verizon.

Risks Related to the Securities Markets and this Offering

   The trading price of the Class A common stock will anticipate the dilution
that will result from future conversion of the Class B common stock.

   We expect that upon completion of this offering, the trading price of the
Class A common stock will reflect the dilution that would result from the
future conversion of Class B common stock. This will likely result in the
shares of our Class A common stock trading at prices substantially lower than
they otherwise would without this future dilution. After this offering, the
Class A common stock will represent 90.5% of our outstanding common stock and
the Class B common stock will represent 9.5% of our outstanding common stock.
If Verizon is successful in satisfying the requirements of the proposal to the
FCC and is able to convert into 800 million shares of our Class A common stock
or Class C common stock, it or its transferees would be able to convert their
shares into shares of common stock representing up to 82% of our outstanding
common stock after this offering. Therefore, investors should recognize that
the Class B common stock may well be converted into approximately 82% of our
outstanding common stock, leaving the Class A common stock as representing
approximately 18% of our outstanding common stock.

   The Class A common stock has limited voting rights in certain
circumstances.

   Our charter provides that so long as 50% of the shares of Class B common
stock outstanding at the completion of this offering remains outstanding,
including additional shares of Class B common stock issued to Verizon in
connection with the exercise of the underwriters' over-allotment option, no
person or group of persons acting together may vote more than 20% of our
outstanding shares of Class A common stock.

                                      20
<PAGE>





   The market price of our Class A common stock may be materially adversely
affected by market volatility.

   The price at which our Class A common stock will trade following this
offering is likely to be highly volatile and may fluctuate substantially. The
price of the Class A common stock that will prevail in the market after this
offering may be higher or lower than the price you pay, depending on many
factors, including:

  . our actual or anticipated quarterly results of operations, which may
    experience significant fluctuations;

  . changes in financial estimates of our revenues and operating results by
    securities analysts;

  . increased capital expenditures or delays in the expansion of our capacity
    and network infrastructure;

  . actual or perceived difficulties in our ability to obtain sufficient
    financing on acceptable terms to fund our capital expenditures;

  . announcements by us or our competitors of new services, significant
    acquisitions or strategic partnerships;

  . a loss of or decrease in sales of services to major customers or a
    failure to complete significant transactions;

  . additions or departures of key personnel;

  . future sales of our common stock, particularly by our directors and
    officers; and

  . commencement of, or involvement in, litigation.

   In addition, the stock market has from time to time experienced significant
price and volume fluctuations that have affected the market prices for the
securities of technology companies. As a result, investors in our Class A
common stock may experience a decrease in the value of their Class A common
stock regardless of our operating performance or prospects. The fluctuations in
the price of our Class A common stock may affect our visibility and credibility
in the Internet infrastructure services market and may affect our ability to
secure additional financing on acceptable terms, if at all.



   You may suffer substantial dilution in the book value of your investment.

   Assuming the Class B common stock outstanding on the date of this offering
converted into the maximum number of shares of common stock permitted under our
certificate of incorporation, the initial public offering price per share will
significantly exceed the net tangible book value per share. Accordingly,
investors purchasing shares in this offering may suffer substantial dilution of
$9.55 per share in their investment, assuming the conversion of Class B common
stock into Class A common stock and an initial public offering price of $13.50
per share. You should refer to the information in the section entitled
"Dilution" for more information.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

   We have made statements under the captions "Prospectus Summary", "Risk
Factors", "Management's Discussion and Analysis of Financial Condition and
Results of Operations", "Business" and in other sections of this prospectus
that are forward-looking statements. In some cases, you can identify these
statements by forward-looking words such as "may", "might", "will", "should",
"expects", "plans", "anticipates", "believes", "estimates", "intends",
"future", "potential" or "continue", the negative of these terms and other
comparable terminology. These forward-looking statements, which are subject to
risks, uncertainties, and assumptions about us, may include, among other
things, projections of our future financial performance, our anticipated growth
strategies and anticipated trends in our business as well as projections
relating to our capital expenditure requirements, our network expansion plans,
locations of new data centers, network operations centers and points of
presence, expected deployment dates for capacity on trans-oceanic cable, our
plans for transitioning customer traffic from leased capacity to our network,
research and development initiatives and increases in sales and marketing
personnel. These statements are only predictions based on our current
expectations and projections about future events. Because these forward-looking
statements involve risks and uncertainties, there are important factors that
could cause our actual results, level of activity, performance or achievements
to differ materially from the results, level of activity, performance or
achievements expressed or implied by the forward-looking statements, including
those factors discussed under the caption entitled "Risk Factors". You should
specifically consider the numerous risks outlined under "Risk Factors".

                                USE OF PROCEEDS

   We estimate that the net proceeds from our sale of the 173,913,000 shares of
Class A common stock we are offering will be approximately $2.3 billion,
assuming an initial public offering price of $13.50 per share and after
deducting estimated underwriting discounts and offering expenses payable by us.
If the underwriters' over-allotment option is exercised in full, we estimate
that our net proceeds will be approximately $2.6 billion.

   Of the net proceeds of this offering, we intend to use approximately $1.8
billion for capital expenditures in connection with the expansion of our
network infrastructure and the balance will be used for general corporate
purposes, including working capital. We may also use a portion of the net
proceeds to acquire or invest in businesses or products or to obtain the right
to use complementary technologies. We have no current commitments or agreements
with respect to any acquisition or investment. Pending these uses, we intend to
invest the net proceeds in short-term, investment-grade, interest-bearing
securities.



                                DIVIDEND POLICY

   We have never declared or paid cash dividends on our capital stock. We
currently expect to retain earnings, if any, to finance the growth and
development of our business. Therefore, we do not anticipate declaring or
paying cash dividends on our common stock in the foreseeable future. The
decision to pay dividends will be made by our board of directors from time to
time in light of conditions then existing including, among other things, our
results of operations, financial condition and capital expenditure
requirements. We must also obtain the consent of Verizon to declare
extraordinary dividends or make other extraordinary distributions on our Class
A common stock. You should refer to the section in "Related Party Transactions"
entitled "Recapitalization Agreement" for more information on this limitation.

                                 CAPITALIZATION

   The following table sets forth our capitalization as of March 31, 2000:

  . on an actual basis giving effect to the recapitalization that will take
    effect before this offering; and

  . on a pro forma as adjusted basis to give effect to a $178 million capital
    contribution by GTE and the sale of the shares of Class A common stock
    offered by us in this offering at an assumed initial public offering
    price of $13.50 per share, after deducting estimated underwriting
    discounts and offering expenses payable by us.

   This table should be read in conjunction with "Selected Combined Financial
Data", "Management's Discussion and Analysis of Financial Condition and Results
of Operations" and our combined financial statements and accompanying notes

                                    DILUTION

   After this offering, the Class A common stock will represent 90.5% of our
outstanding common stock and the Class B common stock will represent 9.5% of
our outstanding common stock. The Class B common stock is convertible at any
time into shares of our Class A common stock representing 10% of our total
common stock outstanding after the conversion. In circumstances that we
describe elsewhere in this prospectus, our Class B common stock can convert
into 800 million shares of Class A common stock or Class C common stock. We
have prepared the information below to show the effect of this offering on our
pro forma net tangible book value per share under either conversion.

   Our pro forma net tangible book value as of March 31, 2000 was approximately
$1.6 billion. Pro forma net tangible book value per share represents our total
tangible assets, assuming a capital contribution of $178 million by GTE, less
our total liabilities. Assuming conversion of the Class B common stock into
shares of Class A common stock representing 10% of our total common stock
outstanding after the conversion, our pro forma net tangible book value per
share as of March 31, 2000 was approximately $82.75 per share. Assuming the
conversion of the Class B common stock into 800 million shares of Class A
common stock or Class C common stock, our pro forma net tangible book value per
share as of March 31, 2000 was approximately $2.00 per share. The accretion or
dilution in pro forma net tangible book value per share shown in the table
below represents the difference between the amount per share paid by purchasers
of shares of our Class A common stock in this offering and the net tangible
book value per share of our common stock immediately following this offering.

   Without taking into account any changes in pro forma net tangible book value
after March 31, 2000, other than to give effect to the sale of the shares of
Class A common stock offered by us at an assumed initial public offering price
of $13.50 per share, after deducting estimated underwriting discounts and
offering expenses payable by us, our pro forma as adjusted net tangible book
value as of March 31, 2000 would have been approximately $3.8 billion, or
$19.92 per share of common stock assuming a 10% conversion, and $3.95 per share
of common stock assuming a conversion into 800 million shares. Such amounts
result in dilution of $62.83 per share to GTE, our sole stockholder, on the 10%
conversion basis and dilution of $9.55 per share to new investors purchasing
shares of Class A common stock on the 800 million share basis. If the initial
public offering price is higher or lower, the dilution to new investors will be
greater or less. The following table illustrates the accretion and dilution in
pro forma net tangible book value per share to new investors:

                        SELECTED COMBINED FINANCIAL DATA

   The selected combined financial data set forth below should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the combined financial statements and
accompanying notes included elsewhere in this prospectus. The selected combined
balance sheet data as of December 31, 1998 and December 31, 1999 and the
selected combined results of operations for each of the years in the three-year
period ended December 31, 1999 have been derived from our combined financial
statements, which have been audited by Arthur Andersen LLP, independent public
accountants, and are included elsewhere in this prospectus. The selected
combined balance sheet data as of March 31, 2000 and results of operations for
each of the quarters ended March 31, 1999 and 2000 have been derived from our
unaudited financial statements included in this prospectus. The results of
operations of the predecessor to Genuity for the six months ended June 30,
1997, have also been derived from financial statements which have been audited
by Arthur Andersen LLP and are included elsewhere in this prospectus.

   Our selected combined balance sheet data as of December 31, 1995, 1996 and
1997 and March 31, 1999 and the selected combined statement of operations data
for each of the years in the two year period ending December 31, 1996 were
derived from unaudited financial statements that are not included in this
prospectus. The selected combined balance sheet data of the predecessor to
Genuity as of December 31, 1995 and 1996 and June 30, 1997 and the selected
combined results of operations data of the predecessor for each of the years in
the two year period ended December 31, 1996 were derived from unaudited
financial statements that are not included in this prospectus. The unaudited
financial statements include all adjustments, consisting of normal recurring
accruals, which we consider necessary for a fair presentation of the results of
operations for these periods.

   Our selected combined financial data set forth below, as of December 31,
1995, 1996, 1997, 1998 and 1999 and for each of the five years in the period
ended December 31, 1999 include the financial position and results of
operations of those operations that will constitute Genuity as of the
completion of this offering. The selected combined financial data as of
December 31, 1995 and 1996 and the results of operations for each of the years
in the two-year period ended December 31, 1996 do not include the financial
data of BBN Corporation. GTE acquired BBN Corporation effective June 30, 1997.
This acquisition was accounted for as a purchase business combination and,
consequently, the results of operations of BBN Corporation, excluding the
operations of BBN Technologies, which are being retained by GTE, are only
included in our results of operations for periods after June 30, 1997. The
results of operations of our predecessor represent the results of operations of
BBN Corporation, excluding the operations of BBN Technologies. The operations
of BBN Technologies are not included in the financial results of either the
predecessor or Genuity.

   We have prepared the accompanying table to reflect our historical combined
financial information in a manner consistent with stand-alone operations by
reflecting transactions of GTE and balances attributable to us in our financial
statements for all periods presented. The historical financial information may
not be indicative of our future performance and does not necessarily reflect
what our financial position and results of operations would have been had we
operated as a separate, stand-alone entity during the periods covered.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   You should read the following discussion in conjunction with our combined
financial statements and the accompanying notes and other financial information
appearing elsewhere in this prospectus.


Components of Revenues

   We derive our revenues from three operating segments: access, hosting and
transport. Our other revenues include international and value-added e-business
services.

   Access. Our Internet access services include dial-up, dedicated and digital
subscriber lines. Our access revenues, which are derived from service providers
and enterprise customers, are the largest component of our total revenues.
Internet access customers typically sign one or two-year contracts providing
for monthly-recurring service fees that are either fixed or based on capacity
utilization. We also include in our access segment those revenues relating to
the development, operation and maintenance of a nationwide dial-up network for
America Online. We derived approximately 42% of our total revenues from America
Online in 1997, approximately 53% in 1998, 52% in 1999 and 46% in the first
quarter of 2000. Although we expect our revenues from America Online to
increase in absolute dollar amounts, we also expect these revenues to decline
as a percentage of our total revenues as we expand and broaden our revenue
base. In December 1999, we extended our strategic relationship with America
Online to provide it with additional dial-up as well as broadband backbone
Internet services. In December 1999, we agreed to operate the existing dial-up
network for AOL Japan, Inc., and we will be responsible for a significant
portion of the continued expansion of that network. Our expanded contractual
relationship with America Online extends through 2006. You should refer to the
section in "Business" entitled "Our Relationship With America Online".

   We also include in access revenues those revenues derived from our provision
of dedicated Internet access to AT&T for resale to customers of its Business
Communications Services Division in the United States. We derived approximately
10% of our total revenues from AT&T in 1997. That percentage decreased to
approximately 7% in 1998 and approximately 2% in 1999 because our strategic
relationship with AT&T, under which BBN Corporation acted as the exclusive
provider for these services, was terminated in September 1997.

   Hosting. Our web hosting services provide reliable hosting and a high speed
network infrastructure as well as flexible, fast and secure hosting platforms
and an experienced technical support staff. Our web hosting services include
managed hosting, collocation, content delivery and high availability services.
Our hosting revenues are based primarily on monthly fees for server management,
physical facilities and bandwidth utilization. Our web hosting services
contracts typically range from one to two years.

   Transport. We provide a broad range of transport services. These services
are generally purchased by telecommunications carriers and Internet service
providers requiring additional capacity and do not include Internet access
services. Our transport revenues are typically based on available bandwidth.
Our transport services contracts typically range from one to two years.

   Other. Other revenues include the results of our international business,
which consist primarily of Internet access, and domestic value-added e-business
services, such as managed security services, virtual private networks for
secure data transmission and the transport of voice communications that have
been converted to IP, commonly referred to as voice-over-IP. We charge for
international access and hosting revenues on a basis consistent with our
domestic services. We charge for our security and virtual private network
services on a fixed, monthly recurring fee basis and we charge for our voice-
over-IP services based on usage. The terms of our value-added e-business
service contracts typically range from one to two years.

                                       29
<PAGE>

   We believe that our hosting and other revenues will increase substantially
as a percentage of our total revenues. We also expect to continue to experience
declining prices in our access and transport services in the foreseeable
future.

Components of Operating Expenses

   Cost of Goods Sold. Cost of goods sold consists primarily of the costs of
leasing telecommunications circuits and labor and expenses of operating our
network infrastructure. We also include in cost of goods sold the salaries and
benefits of our technical, operations and customer service personnel as well as
facilities administration, including rent, maintenance and utilities to support
our data centers.

   We expect our network infrastructure requirements to grow in conjunction
with the growth of our overall business and, accordingly, expect our cost of
goods sold to increase significantly in the future. We believe our investments
in network infrastructure will cause our total data transmission costs to
increase substantially in the near term because of higher network operating and
maintenance expenses associated with this expansion. Although we expect our
total data transmission costs to increase significantly in absolute dollar
amounts as we expand, we also expect them to decline as a percentage of
revenues in the future as we add and utilize additional capacity and migrate
customers from our leased facilities to our own network.

   Selling, General and Administrative. Selling, general and administrative
expenses consist primarily of salaries and benefits for our marketing, sales
and support personnel, advertising, trade shows, professional fees and legal
and accounting services and other miscellaneous expenses. We expect selling,
general and administrative expenses in the future to increase in absolute
dollar amounts as we hire additional personnel, expand our operations, invest
in new support systems and incur additional costs related to the growth of our
business. More specifically, we expect that advertising expenses will increase
substantially in the near term as we launch our advertising and branding
campaign and substantially increase our sales force. However, we expect
selling, general and administrative expenses to decline as a percentage of
revenues.

   Depreciation and Amortization. Depreciation and amortization expenses
consist primarily of depreciation of our network infrastructure, including data
center equipment and related assets, and amortization of our goodwill and other
intangible assets. We expect these expenses to increase in the future as we
invest significant capital to expand our network infrastructure and data center
capacity.

   In 1999, we completed the initial build-out of our high speed fiber network
infrastructure in the United States and have started adding additional layers
of capacity to meet existing and anticipated market demand. Our network
infrastructure has over 17,500 route miles of optical fiber connecting over 100
metropolitan areas in the United States. Through our recent investments in
undersea fiber optic cable capacity, we have expanded the reach of our network
into Europe and Asia.

Basis of Presentation

   Our selected combined financial data as of December 31, 1995, 1996, 1997,
1998 and 1999 and March 31, 1999 and 2000 and for each of the five years in the
period ended December 31, 1999 and the three months ended March 31, 1999 and
2000 include the financial position and results of operations of those
operations that will constitute Genuity as of the completion of this offering.
Our combined financial data as of December 31, 1995 and December 31, 1996 and
our results of operations for each of the two years in the period ended
December 31, 1996 do not include the financial data of BBN Corporation. GTE
acquired BBN Corporation effective June 30, 1997. This acquisition was
accounted for as a purchase business combination and, consequently, the results
of operations of BBN Corporation, excluding the operations of BBN Technologies,
which are being retained by GTE, are only included in our results of operations
for periods after June 30, 1997. The results of operations of our predecessor
represent the results of operations of BBN Corporation, excluding the
operations of BBN Technologies.

   The following table sets forth our results of operations data derived from
our audited financial statements and unaudited financial statements for the
three months ended March 31, 1999 and 2000. For the purposes of the following
discussion and analysis, the pro forma results of operations for the year ended
December 31, 1997 combine the results of operations of our predecessor for the
six months ended June 30, 1997 with the results of operations of Genuity for
the year ended December 31, 1997, which includes the post-acquisition results
of our predecessor effective July 1, 1997. This presentation was included to
permit useful and complete year-to-year comparisons between the results of
operations for the years ended December 31, 1997, 1998 and 1999. However, this
pro forma restated information is not necessarily indicative of the operating
results we would have achieved if we had acquired our predecessor on January 1,
1997. The first six months of 1997 did not include some operating expenses,
amortization expense and allocations from GTE for centralized corporate
services and infrastructure costs, which were included in the second six months
of the year.

</TABLE>

   Our revenues in the first quarter of 2000 increased $91 million, or 58%,
over the first quarter of 1999. The first quarter of 1999 included
approximately $11 million of revenues associated with our strategic
relationship with AT&T. This contract has been terminated. If we exclude those
revenues from the first quarter of 1999, total revenues increased 70%.

   Access. Our access revenues in the first quarter of 2000 increased $55
million, or 43%, over the first quarter of 1999. The increase in access
revenues reflects an 80% increase in dial-up access modems deployed and a 24%
increase in dedicated access customers. These increases were offset in part by
lower prices, including the pricing structure associated with our new contract
with America Online.

   Hosting. Our hosting revenues in the first quarter of 2000 increased $12
million, or 116%, over the first quarter of 1999, due to an increase in the
number of our managed hosting customers.

   Transport. Our transport revenues in the first quarter of 2000 increased $10
million, or 75%, over the first quarter of 1999 due primarily to the increased
sale of private line services.

                                       32
<PAGE>


   Other. Other revenues in the first quarter of 2000 increased $14 million, or
239%, over the first quarter of 1999 due to a $5 million increase in sales of
Internet access services in international markets and an $8 million increase in
value-added e-business services.

Operating Expenses

   Costs of Goods Sold. Our cost of goods sold in the first quarter of 2000
increased $123 million, or 77%, over the first quarter of 1999. The increase
was the result of the continued build out of our network infrastructure to
provide access to a broader base of customers, support a growing customer base
and provide increased scope to service customers of our Internet access
services. Cost of goods sold, as a percentage of total revenues, was 115% in
the first quarter of 2000 compared to 102% in the first quarter of 1999. The
new pricing structure associated with the America Online contract contributed
to the increase.

   Selling, General and Administrative Expenses. Our selling, general and
administrative expenses in the first quarter of 2000 increased $15 million, or
16%, over the first quarter of 1999. This increase is attributable to costs
associated with the expansion of our sales force and our marketing
organization.

   Depreciation and Amortization. Our depreciation and amortization in the
first quarter of 2000 increased $13 million, or 31%, over the first quarter of
1999. The increase is the result of capital expenditures associated with the
continued build out of our network infrastructure.

Net Loss

   Our net loss increased to $210 million in the first quarter of 2000 compared
to $139 million in the first quarter of 1999. We expect to continue to incur
significant net losses over the next several years, given our planned operating
and capital expenditures.

</TABLE>

   Our revenues for 1999 increased $260 million, or 58%, over 1998. Our
revenues for 1998 increased $156 million, or 54%, over 1997.

   Access. Our access revenues in 1999 increased $205 million, or 58%, over
1998. Our access revenues in 1998 increased $128 million, or 57%, over 1997.
These increases were due to an 87% increase in 1999 and a 76% increase in 1998
in the number of dial-up access modems deployed, primarily resulting from our
expanded relationship with America Online, and to a lesser extent, an increase
in the number of dedicated access customers. These increases were, in each
year, offset in part by lower prices.

   Hosting. Our hosting revenues in 1999 increased $15 million, or 46%, over
1998, due to a 23% increase in the number of our managed hosting customers. Our
hosting revenues in 1998 increased $14 million, or 73%, over 1997 due in large
part to our acquisition of a web hosting company in December 1997.

   Transport. Our transport revenues in 1999 increased $18 million, or 38%,
over 1998, due to the sale of excess capacity on our network as we brought new
network segments on line. Our transport revenues in 1998 increased $5 million,
or 12%, due to increased sale of private line services.

   Other. Other revenues in 1999 increased $23 million, or 152%, over 1998 due
to an $18 million increase in sales of Internet access services in
international markets and a $4 million increase in sales of voice-over-IP and
managed security services. Other revenues in 1998 increased $9 million, or
164%, over 1997, due to a $5 million increase in international revenues and a
$3 million increase in sales of managed security services.

Operating Expenses

   Cost of Goods Sold. Our cost of goods sold in 1999 increased $275 million,
or 56%, over 1998, and our cost of goods sold in 1998 increased $234 million,
or 90%, over 1997. Our cost of goods sold, in each case, increased as a result
of the build-out of our network infrastructure to provide access to a broader
base of customers, support a growing customer base and provide increased scope
to service customers of our Internet access services. Our continued expansion
of the dial-up network operated for America Online also contributed to the
increase in cost of goods sold in 1999.

   Our cost of goods sold, as a percentage of total revenues, was 89% in 1997,
110% in 1998 and 109% in 1999. To the extent we are able to increase our base
of customers and correspondingly increase our revenues, we expect cost of goods
sold to decrease as a percentage of our total revenues. Our telecommunications
circuit costs represent a substantial percentage of cost of goods sold. These
costs, which largely relate to long haul circuits, are expected to decrease as
a percentage of our revenues as we migrate customers from our leased facilities
to our own network.

   Selling, General and Administrative Expenses. Our selling, general and
administrative expenses in 1999 increased $84 million, or 27%, over 1998. This
increase was due to a $67 million increase in selling expenses that were
directly attributable to an increase in the number of sales and sales-related
employees, both domestically and internationally. The growth in our sales force
resulted in higher training expenses and additional costs for expansion of
field offices. Also contributing to this increase was a $17 million increase in
general and administrative expense resulting from the hiring of additional
management staff and related operating expenses, increased facilities costs and
increased information technology expenses.

   Our selling, general and administrative expenses in 1998 increased $131
million, or 72%, over 1997. Selling expenses increased $45 million due to
customer growth, higher new product development costs and investment in our
sales and marketing infrastructure, including expansion of sales channels,
advertising costs and other promotional activities related primarily to
Internet-based services for enterprise and service providers. General and
administrative expenses increased $86 million due to increases in management
staff and related operating expenses across the organization, as well as
increased cost of Year 2000 renovation and system testing.

   Depreciation and Amortization. Our depreciation and amortization expenses in
1999 increased $83 million, or 80%, over 1998. This increase reflects our
continuing investment in our network infrastructure in order to support our
growth in customers and services. At December 31, 1999, over 17,500 miles of
our fiber optic network were operational and, therefore, being depreciated.

   Our depreciation and amortization increased $44 million, or 74%, in 1998
over 1997. The increase reflects the continuing investment in our network
infrastructure, which had over 5,900 miles of fiber deployed and operational
and, therefore, being depreciated. In 1998 we also had a full year of
amortization of goodwill related to two acquisitions in 1997, compared to a
half year of amortization expense in 1997.

 Net Loss

   Our net losses increased to $647 million in 1999 compared to $469 million in
1998 and $213 million in 1997. Our net losses increased to $210 million in the
first quarter 2000 compared to the first quarter 1999. Given our planned
operating and capital expenditures, we expect to continue to incur significant
net losses over the next several years.

Income Taxes

   Our tax provision was computed on a stand-alone basis. Since July 1, 1997,
our federal income tax returns have been filed on a consolidated basis with
GTE. We generated taxable losses of $115 million in 1997, $527 million in 1998,
$638 million in 1999 and $179 million in the first quarter of 2000, which were
benefited by GTE in its consolidated income tax return. We received
reimbursements for these tax benefits of $40 million, $186 million and $224
million for the years ended December 31, 1997, 1998 and 1999 and $62.5 million
for the three-month period ended March 31, 2000. To reflect our income tax
provision on a basis that will be comparable to future periods, these
reimbursements have been accounted for as capital contributions. Our tax
provision represents amounts owed for state taxes. Our ability to use net
operating losses may be subject to annual limitations. We may also pay income
taxes in the future due to operating income in some states and foreign
countries. In the future, if we achieve operating profits and the net operating
losses have been exhausted or have expired, we may experience significant tax
expense.

Quarterly Results of Operations

   The following table sets forth our unaudited quarterly results of operations
data for each of the nine quarters in the period ended March 31, 2000. This
data has been derived from our unaudited combined financial statements. We
believe that this information has been prepared on the same basis as our
audited combined financial statements and that all necessary adjustments,
consisting only of normal recurring adjustments, have been included to present
fairly the selected quarterly information when read in conjunction with our
audited combined financial statements and accompanying notes included elsewhere
in the prospectus. The operating results for any particular quarter are not
necessarily indicative of the operating results for any future period.

Liquidity and Capital Resources

   We have used cash in our operating and investing activities during all
periods. We have funded these cash requirements principally through permanent
contributions to capital from GTE and borrowings from its affiliates. Capital
contributions amounted to $611 million in 1997, $1.3 billion in 1998, $974
million in 1999 and $488 million in the first quarter of 2000. We expect to
continue to fund all of our cash requirements prior to this offering through
permanent contributions of capital from GTE.

   Net cash used in operating activities was $91 million in 1997, $513 million
in 1998 and $404 million in 1999. Net cash used in operating activities was
$119 million in the first quarter of 2000. Net cash used in operating
activities for these years and the three-month period was primarily the result
of operating losses.

   Net cash used in investing activities was $774 million in 1997, $505 million
in 1998 and $701 million in 1999. Net cash used in investing activities in each
of these years was primarily the result of capital expenditures for
construction of our network infrastructure, as well as leasehold improvements,
furniture, fixtures, computers and other equipment. Our capital expenditures
for the three-year period ended December 31, 1999 totaled over $1.4 billion.
Our net cash for investing activities in 1997 included the acquisitions of BBN
Corporation, our predecessor, and a web hosting company, which together totaled
$518 million. Net cash used in investing activities was $212 million for the
first quarter of 2000 due primarily to the result of capital expenditures for
the continued construction of our network infrastructure. Our capital
expenditures in the first quarter of 2000 were $211 million.

   We currently intend to spend approximately $1.8 billion to $2.0 billion
during the year ended December 31, 2000 on capital expenditures, of which
approximately $1.2 billion is expected to be spent on the continued expansion
of our fiber optic network and approximately $250 million is expected to be
spent on the construction of additional data centers. As of March 31, 2000, we
had entered into $401 million in commitments for these projected expenditures.

   Our capital expenditures program, as currently contemplated, will require
between $11 billion and $13 billion over the five-year period ending December
31, 2004, the majority of which will be for the expansion of our network
infrastructure. We expect capital expenditures to continue to increase
significantly beyond this period, depending on the pace at which we build and
expand our network infrastructure and increase our employee base to support our
operations and invest in our selling and marketing organization. In the near
term, we believe that the proceeds from this offering, along with the capital
contribution from GTE prior to this offering that will offset intercompany debt
as well as any outstanding external debt as of the closing of the offering,
should be sufficient to meet our cash needs through the first quarter of 2001.

   Our future cash requirements, however, will depend on a number of factors,
including:

  .  the pace at which we expand our network infrastructure and the
     associated costs;

  . the rate at which customers purchase our services and the pricing of
    those services;

  . the level of marketing required to build our brand, to acquire and retain
    customers and to maintain a competitive position in the marketplace;

  . the rate at which we invest in support systems and engineering; and

  . investment opportunities in complementary businesses or technologies.

   We will be required to raise additional capital to fund our business plan as
currently contemplated. We cannot predict the timing and exact amount of
capital that we will be required to raise. We expect to raise this capital
principally through public offerings or private placements of debt or equity
securities, depending on market conditions. The issuance of additional equity
would be dilutive to the holders of our Class A common stock. We are required
to obtain the consent of Verizon or other future holders of our Class B common
stock

                                       36
<PAGE>


prior to issuing shares of our capital stock in excess of specified limits and
our agreement with Verizon limits our ability to incur debt in excess of agreed
upon amounts. You should refer to "Description of Capital Stock" and the
section in "Related Party Transactions" entitled "Recapitalization Agreement"
for more information regarding limitations imposed on us by our charter and
contractual relationship with Verizon. If we are unable to obtain required
additional capital through the issuance of these securities or are required to
obtain it on terms less satisfactory than we desire, we may be required to
delay the expansion of our business.

   As of March 31, 2000, our indebtedness included $49 million of 6%
convertible subordinated debentures. These debentures are due in 2012 and may
be converted at any time by the bondholders into cash at an exchange ratio of
$966.67 for each $1,000 in principal amount of debentures. The debentures are
unsecured obligations of Genuity and are subordinated in right of payment to
our senior indebtedness, if any. We are required to contribute to a sinking
fund annual payments equal to 5% of the aggregate principal amount issued. As
of December 31, 1999, we had purchased and retired debentures with an aggregate
principal of $37.3 million, which satisfies the annual sinking fund
requirements through 2006.


   As of March 31, 2000, our indebtedness also included $83 million in capital
leases. The capital leases bear interest at 5.07% to 9.50% and have terms of 5
years from the date of purchase, with principal and interest payable quarterly
in advance.

   In addition, in the future we may wish to selectively pursue possible
strategic investments in businesses, technologies or products complementary to
ours in order to expand our geographic presence and achieve operating
efficiencies. We may not have sufficient liquidity, or we may be unable to
obtain additional debt or equity financing on favorable terms or at all, to
finance these investments.

Year 2000

   We do not believe that the Year 2000 rollover has had, or will have, any
material adverse impact on our operating results or liquidity. We have not
experienced any material contingencies with customers or major suppliers nor
have we experienced any significant Year 2000 events. The estimated total cost
of our Year 2000 compliance efforts is expected to total approximately $60
million, of which $54 million has been expended through March 31, 2000.

Inflation

   We do not believe that inflation has had a material adverse impact on our
business or operating results during the periods presented.

Recently Issued Accounting Pronouncements

   The Securities and Exchange Commission issued Staff Accounting Bulletin
(SAB) No. 101, Revenue Recognition in Financial Statements, on December 3,
1999. We are required to adopt this new accounting guidance, as amended by SAB
No. 101A, no later than the second quarter of 2000. We implemented this
accounting guidance in the first quarter of 2000.

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives) and for hedging activities. SFAS No. 133, as amended by SFAS No.
137, is effective for all fiscal quarters of fiscal years beginning after June
15, 2000. This new standard is not anticipated to have an impact on our
combined financial statements based on our current structure and operations.

Quantitative and Qualitative Disclosure About Market Risk

   While our long-term debt bears fixed interest rates, the fair value of our
fixed rate long-term debt is sensitive to changes in interest rates. There is a
risk that market rates will increase and the required payments will exceed
those based on the current market rates. The estimated fair value of long-term
debt based on a debt pricing model was lower than its recorded value by
approximately $1.2 million as of December 31, 1998, by approximately $6.6
million as of December 31, 1999 and by approximately $6.8 million as of March
31, 2000. Under our current risk management policies, we do not use interest
rate derivative instruments to manage our exposure to interest rate changes.

                                    BUSINESS

Overview

   We are a leading e-business network provider of high quality, managed
Internet infrastructure services to enterprises and service providers. We offer
a comprehensive suite of managed Internet infrastructure services, including:

  . Internet access through dial-up, dedicated and digital subscriber lines;

  . web hosting and content delivery; and

  . value-added e-business services, such as virtual private networks for
    secure data transmissions and security services.

   We operate a state-of-the-art global network that consists of:

  . recently deployed broadband fiber optic cable in the United States;

  . points of presence, which are locations where we provide Internet access
    to end users;

  . secure data centers with redundant fiber connections to our network and
    backup power sources; and

  . undersea and international fiber optic cable capacity.

   Our large base of on-network users and content, combined with our extensive
network, positions us as one of the leading Internet backbone providers in the
world, a status commonly referred to as a Tier 1 Internet backbone provider.
Tier 1 Internet backbone providers have the network scale and on-network
traffic to offer their customers connectivity to virtually all addresses on the
Internet either directly through their Internet backbone or through cost-free,
high speed private connections to other Tier 1 Internet backbones. We believe
that service providers are increasingly connecting to networks with substantial
on-network content to improve the quality of their customers' experience, which
in turn drives demand by enterprises seeking to connect to networks with large
numbers of users. We believe that by taking advantage of this demand cycle,
which we call the "network effect", we will continue to drive significant
demand for our services from both enterprises and service providers and
differentiate ourselves from non-Tier 1 Internet backbone providers.

Industry Background

 The Growing Importance of the Internet

   The Internet has experienced tremendous growth in the past decade and has
emerged as an important global medium for communications and commerce. The
growth in data that is transmitted over the Internet is driven by a number of
factors, including the rapidly increasing number of network-enabled and
Internet-based applications, the growing number of personal computers linked to
the Internet, advances in network-enabled devices, servers and routers and the
increasing availability of broadband connections.

   The explosive growth of the Internet and the increasing demand for data
services are expected to continue. According to International Data Corporation,
the number of Internet users worldwide will increase from 142 million at the
end of 1998 to approximately 502 million by the end of 2003. In addition,
according to International Data Corporation, the number of web pages is
expected to grow from 1.7 billion in 1999 to approximately 13.1 billion in
2003. This growth is expected to lead to a substantial increase in the demand
for bandwidth and other Internet infrastructure services.

   The proliferation of the Internet within the business environment, in
particular, has been substantial. Once primarily used for e-mail and retrieving
information, the Internet is now being used as a communications platform for an
increasing number of mission-critical Internet-based applications, such as
those relating to

                                       39
<PAGE>

e-commerce, internal networks or intranets, telephone and facsimile
capabilities, supply chain management, customer service and project
coordination via extranets. The Gartner Group estimates that worldwide
business-to-business e-commerce sales will grow from $145 billion in 1999 to
approximately $7.3 trillion in 2004.

   To improve the effectiveness and scalability, of their critical Internet-
based applications, both enterprises and service providers are requiring
increasing levels of network performance, including capacity, reliability,
security and manageability, across the Internet.

 The Growing Demand for Outsourced Internet Infrastructure Solutions

   As the Internet and data traffic have grown, the cost and complexity for
enterprises and service providers to manage their own network infrastructure
demands in-house has increased. Traditionally, enterprises were required to
make substantial investments in developing the Internet expertise and
infrastructure necessary to ensure the quality, reliability, security and
availability of their Internet operations. The implementation and maintenance
of Internet infrastructure solutions also require significant technical
expertise and capital expenditures in a number of other areas, such as e-
commerce systems, security and privacy technologies, advanced user interface
and multimedia production. Moreover, the information technology departments
within enterprises are constantly challenged by the need to implement their
Internet business strategy, adopt new and rapidly changing technologies,
transition to new broadband content applications and continuously update
dynamically changing content. As a result, enterprises are seeking Internet
infrastructure service providers that can minimize their exposure to the
capital, human and technological risks associated with in-house solutions. To
increase their competitive edge, enterprises are now outsourcing their critical
Internet operations to increase performance and scalability, speed time-to-
market and reduce costs.

   Similarly, service providers are challenged by the rapid growth and
increasing complexity of the Internet infrastructure, the dramatic increase in
data traffic and the growing need to meet the demands of broadband
applications. Service providers are increasingly required to devote substantial
capital and human resources to expanding the capacity and the technological
capabilities of their networks. As the demands of their customer base grow,
these service providers find it more difficult to quickly, cost-effectively and
efficiently deliver service through internal infrastructure expansion. As a
result, service providers are increasingly focusing their resources on sales
and marketing and outsourcing their Internet infrastructure requirements to
organizations focused on developing and enhancing a high capacity Internet
infrastructure that can be quickly expanded to meet their requirements.

 The Development of the Internet Infrastructure Services Market

   The growing demand from enterprises and service providers for outsourced
Internet infrastructure services has led to the development of an Internet
infrastructure service market comprised of companies focused on solving these
outsourcing requirements. Many of these companies have endeavored to build or
otherwise acquire network facilities in order to provide Internet access, while
others have addressed more specific solutions, such as web hosting or security
services. According to Forrester Research, the Internet access and web hosting
markets in the United States are expected to grow from an aggregate of $4
billion in 1998 to $57 billion by 2003, representing a compound annual growth
rate of approximately 70%.

   Enterprises and service providers are increasingly demanding Internet
infrastructure service providers that can deliver a high quality Internet
experience for their users. The ability to deliver this high quality experience
has become more difficult, largely as a result of an increasing number of
Internet users and richer content, including graphics, photographs and
streaming video and audio. In addition, as the number of networks connected to
the Internet has grown, the delay and loss of data that is transmitted over the
Internet has increased. This is particularly true at the major public peering
points where multiple Internet service providers exchange data over shared
facilities. To increase performance, a number of Internet backbone providers
have established high-speed private connections with other networks to exchange
traffic over dedicated fiber circuits.

                                       40
<PAGE>


These connections are referred to as private peering connections. The quality
of an experience on the Internet is therefore highly dependent on the quality,
capacity and reliability of the physical facilities over which Internet
services are provisioned and the Internet backbone through which Internet
access is provided and content is delivered.

   The critical elements of delivering a high quality user experience are a
large base of on-network users, content, and high speed, well-managed private
peering relationships with other Tier 1 Internet backbones. Internet backbone
providers that have these competitive strengths are able to route traffic to
virtually all Internet addresses and avoid the need to route traffic across
multiple networks and congested public peering points. Consequently, their
users encounter fewer delays due to transmission bottlenecks across public
peering points, and enterprise and service providers using these Internet
infrastructure service providers are better able to manage the quality of
experience of their end users.

   Accordingly, enterprises and service providers increasingly look to the
limited number of providers that offer a comprehensive suite of managed
Internet infrastructure services, a large base of on-network users and content,
and reliable and scalable network facilities. We believe that we are among only
a few companies in the world that offer the full complement of these attributes
as part of their e-business network solution.

America Online, Earthlink, NetZero and Web TV, web hosting services for popular
web sites as Yahoo! and ZDNet, and high speed connections to enterprises that
host their own web sites, such as Microsoft, we carry a significant amount of
traffic over our Tier 1 Internet backbone. We believe enterprises and service
providers choose to connect to our Internet backbone because they can directly
route traffic to, or receive content from, a significant number of other
customers on our network. This capability results in higher transmission
speeds, lower instances of data loss and greater quality of service, thereby
improving the overall quality of experience for Internet users. We believe that
service providers are increasingly connecting to networks with substantial on-
network content to improve the quality of their customers' experience, which in
turn drives demand by enterprises seeking to connect to networks with large
numbers of users. We believe that by taking advantage of this demand cycle,
which we call the "network effect", we will continue to drive significant
demand for our services from both enterprises and service providers and
differentiate ourselves from non-Tier 1 Internet infrastructure service
providers.

   State-of-the-Art Network. We operate a state-of-the-art, high capacity
global fiber optic network that is highly reliable and scalable. Over 85% of
our fiber has been deployed within the past two years, and a majority

                                       41
<PAGE>

of our optical electronic equipment has been installed within the past year.
Our highly redundant fiber optic network architecture is designed to minimize
service interruptions in our network operations. We have significant additional
capacity on our fiber network, which already carries a substantial portion of
our traffic. This capacity allows us to scale quickly at favorable incremental
capital costs as we meet increased customer demands and continue our transition
from leased capacity. We also operate eight data centers in the United States,
one data center in the United Kingdom and one in Japan, through which we
provide managed and collocated web hosting services for enterprises with
critical Internet operations. Through our technologically advanced data
centers, we offer customers a secure environment to house critical Internet
operations and to obtain high bandwidth connectivity to the Internet.

   High Performance, Tier 1 Internet Connectivity. We provide high performance
connectivity to the Internet through our Tier 1 Internet backbone and extensive
high speed private connections to other major Internet backbone providers and,
to a lesser extent, public peering points. Our extensive private peering
relationships permit us to have direct, cost-free exchange of traffic with a
significant number of telecommunications carriers and Internet infrastructure
service providers, thus avoiding the congestion of public peering points when
directing traffic to users connected to those Internet backbones. As a result,
we are able to offer our customers direct access to our on-network users and
content. In addition, over 80% of the traffic we deliver to the rest of the
Internet is delivered through private peering connections.

   Significant Internet Protocol Engineering and Architectural Expertise.
Drawing upon the breadth and depth of our IP and networking experience and
expertise, including over 750 engineers and over 1,100 technicians, we are able
to quickly and cost-effectively identify the Internet infrastructure
requirements of our customers and design and implement appropriate solutions.
For service providers, this entails testing, certifying, deploying and scaling,
within our network, the latest fiber optic and IP routing, switching and web
hosting technology to provide cost-effective and highly reliable managed
Internet infrastructure services. For our enterprise customers, we provide high
quality IP solutions comprised of one or more of our services. For example, we
combine our Internet access, web hosting, virtual private networks and managed
security services to enable secure intranets and extranets for enterprises.

Our Strategy

   Our objective is to be the leading e-business network provider by
architecting, building and operating the infrastructure for the Internet
economy. The principal elements of our strategy for pursuing this objective
include:

   Leveraging the Network Effect. We intend to continue to target enterprises
and service providers with significant Internet infrastructure demands. The
addition of an increasing number of service providers enables us to cost-
effectively scale our network and attract enterprises that seek to connect to
networks with a large number of users. The additional users that these service
providers bring to our network attract enterprises that want to market their
products and services directly to a larger base of users. We believe that
attracting these customers will enhance our position as a leading provider of
managed Internet infrastructure services as a result of the consolidation of a
growing number of users and large volumes of content on our Tier 1 Internet
backbone. We also believe that over time the scale associated with an
increasing customer base will also allow us to pursue premium pricing with
enterprise customers and minimize operating expenses sometimes associated with
private peering connections to other Internet backbones.

   Expanding Our Capacity and State-of-the-Art Network. We intend to continue
to expand our capacity and state-of-the-art network in advance of the capacity
demands of our customers. We plan to do this by accomplishing the following by
the end of 2001:

  . extending our coverage by deploying up to an additional 4,500 route miles
    of fiber optic cable serving approximately 120 metropolitan service areas
    and 11 additional international markets;

  . expanding our network capacity in the United States to the equivalent of
    10 layers of 10 gigabit capacity each;

                                       42
<PAGE>

  . increasing our number of dedicated points of presence to nearly 300 and
    deploying local fiber rings within selected metropolitan service areas to
    increase our reach to end users;

  . adding seven additional data centers in key locations worldwide to
    address the growing demands for our web hosting and content delivery
    services;

  . expanding our network collocation facilities to enable our service
    provider customers to reach new markets quickly and cost-effectively; and

  . deploying state-of-the-art optical electronic equipment to maximize the
    capacity of our fiber network.

   Continuing to Build and Own Our Network Facilities. As we expand, both
domestically and internationally, we intend to build and own the majority of
our network facilities rather than leasing them from other facilities-based
providers. We believe that owning our network facilities:

  . provides greater control over the performance, reliability and breadth of
    our managed Internet infrastructure services;

  . enables us to increase our capacity more quickly to meet increasing
    bandwidth demands;

  . generates higher gross margins than would be generated through leasing
    circuits from other facilities-based providers; and

  . improves service delivery to customers by reducing reliance on third-
    party providers.

   Expanding Our Distribution Capabilities. We intend to develop and expand our
direct sales force and our strategic alliances with other Internet-focused
companies in order to expand our distribution capabilities. Currently, we have
over 350 persons in our direct sales force, and we intend to substantially
increase this sales force by the end of 2001. During the same period, we plan
to substantially increase our Electronic Business Consultant organization,
which is a group of highly skilled sales consultants that aid our existing and
potential customers in designing e-business solutions based on our managed
Internet infrastructure services. In addition, through our eP@rtner Program, we
have formed alliances with leading web integrators, e-business consultants,
interactive agencies and other technology providers. We have formed similar
alliances with international Internet service providers through our
Net.Alliance program. This program enables these Internet service providers to
offer our portfolio of IP-based services to their customers and is designed to
allow us to provide our services to private and commercial customers in key
European, Pacific Rim and Latin American markets. Our current partners in these
programs include, among others, Agency.com, Cambridge Technology Partners,
Cisco Systems, Ernst & Young, Hewlett-Packard, IBM, Lante, Microsoft, Nortel
Networks and Sapient in the United States, Energis in the United Kingdom and
I.NET and Tiscali in Italy. These alliances serve as a valuable, cost-effective
channel for marketing our services. We also plan to expand our existing
reseller relationships to significantly enhance our distribution capabilities.

   Pursuing Strategic Transactions and Alliances. We intend to pursue selective
acquisitions that will allow us to quickly and cost-effectively extend our
geographic presence and customer base, particularly in international markets.
Additionally, we intend to make strategic investments in or enter into joint
ventures or alliances with complementary businesses to broaden our market
presence or expand our strengths in key services. We believe that successfully
pursuing these strategic transactions or alliances will enable us to expand our
geographic and service reach and to broaden our Internet infrastructure
services for our customers.

   Using Our Extensive Internet Protocol and Networking Expertise to Develop
New Services. We intend to use our long history of IP and networking expertise
to strengthen our reputation as a leader in the development and deployment of
innovative Internet infrastructure services. We were one of the first to offer
commercially managed web hosting services and managed security services. We
plan to continue to develop and introduce innovative services that address the
evolving requirements of our enterprise and service provider customers. We are
pursuing initiatives such as IP-based voice virtual private networks, enhanced
multi-media streaming and

                                       43
<PAGE>

content distribution services and wireless and satellite access services. In
addition, we plan to partner with or make investments in innovative Internet
start-ups and other organizations to enhance both our access to and
incorporation of leading technologies.

   Establishing Genuity as a Leading Brand for e-Business Network Services. We
intend to establish Genuity as a leading brand for e-business network services
worldwide. We plan to increase brand awareness by pursuing an aggressive
marketing strategy involving television, radio and print advertising as well as
extensive public relations efforts. We will pursue additional marketing
campaigns specifically targeted at enterprises and service providers. We also
intend to build brand recognition by continuing to work closely with our
eP@rtners and Net.Alliance partners to increase our exposure to a broader base
of customers.

well as the scale and diversity of our services, differentiates us from our
competitors.

   Internet Access. We offer a variety of Internet access services to our
enterprise and service provider customers, including dial-up, dedicated and
digital subscriber lines. We also provide a range of customer premise equipment
that is necessary to connect to the Internet, including routers, channel
service units or data services units, modems, software and other products. Our
Internet access services, which accounted for over 77% of our total revenues in
1999, include:

  . Dial-up Access. Our dial-up access service enables users to connect to
    the Internet using a local telephone number. Our customers can connect to
    our Internet backbone through more than 800 local access points in the
    United States and, through our reseller relationship with iPass, a remote
    access provider, through approximately 1,500 international local access
    points in more than 150 countries. DiaLinxSM, which is our remote dial-up
    access service for enterprises that enables them to provide their mobile
    professionals, telecommuters, customers and business partners with
    guaranteed, cost-effective local dial-up access to their intranets and
    extranets, as well as the Internet, from around the world. Similarly, our
    DiaLinx ISP service enables Internet service providers to expand their
    existing dial-up access service without incurring substantial up-front
    capital costs and ongoing operational expenses. For other Internet
    service providers and organizations that want to quickly offer their
    customers a private-label, Internet dial-up access service without
    incurring up-front and ongoing investments in network infrastructure or
    the burden of providing back office support, we offer a virtual Internet

    metropolitan service areas throughout the United States, with expansion
    planned to over 50 major metropolitan service areas, covering over 60% of
    the United States population, by the end of 2000. Our digital subscriber
    line access services are available in a wide range of dedicated access
    speeds, from 144 kilobits per second to 1.5 megabits per second. Our
    digital subscriber line access services for enterprises are designed to
    meet the needs of telecommuters, branch offices and small businesses by
    providing high quality Internet access at speeds faster than dial-up and
    Integrated Services Digital Network and offered for a fixed monthly fee.
    In addition, for our service provider customers, we coordinate all
    activities necessary to provide digital subscriber line access service,
    including service establishment, network connectivity, bulk billing and
    second tier technical support.

   Web Hosting. Our web hosting services, which accounted for 7% of our total
revenues in 1999, enable enterprises and application service providers to
outsource the storage and management of their web servers to our special
purpose web hosting facilities. Our Enterprise Advantage SM web hosting service
provides reliable web hosting and high speed network infrastructure, flexible,
fast, and secure web hosting platforms and experienced technical support staff.
We currently operate 10 data centers throughout the world, with eight in the
United States, one in Leeds, England and one in Tokyo, Japan. Each data center
is located in the same building as, or in close proximity to, our network
access points. Our data centers are technologically advanced facilities with
redundant, high speed connectivity to the Internet, uninterruptible power
supplies, back-up generators, fire suppression, raised computer floors,
separate cooling zones, seismically braced racks and high levels of security.
Our Enterprise Advantage services include:

  . Managed Web Hosting. Our managed web hosting service provides fully
    managed, secure and reliable web hosting capabilities for businesses
    operating in Windows NT or UNIX environments that want to use our
    expertise to implement and manage their web site infrastructure. We
    manage the systems and platforms and also retain ownership of equipment
    and software.

  . Customer Managed Web Hosting. Our customer managed web hosting service is
    designed for enterprises that require administrative control of their web
    sites but prefer to partner with an experienced, reliable web hosting
    provider. This service provides our customers with pre-configured server
    hardware and software, Internet access and the benefit of secure and
    continuously monitored data centers. Our customers retain full
    responsibility for the content and administration of their web sites.

  . Collocation Web Hosting. Our collocation web hosting service is designed

    responsibility for management, content and administration of their web
    sites, but need a secure and scalable hosting facility with high
    performance connectivity.

  . Content Delivery and High Availability Services. For customers with high
    traffic web sites, we also offer optional, high availability services
    that can increase web site capacity and performance. We currently offer
    four high availability services:

    . LoadBalancer. Our LoadBalancer SM service creates a single web
      address that represents multiple web servers located in a single data
      center. These web servers utilize advanced load balancing techniques,
      based on the number of users seeking access to the web site, to
      connect users to the web server that will produce the fastest
      response to their request.

    . Traffic Distributor. Our Traffic Distributor service is designed for
      web sites requiring high reliability and involves hosting web servers
      in multiple data centers. Enabled by our patent-pending Hopscotch(TM)
      load distribution technology, this service enhances the experience of
      an end user by directing their content requests to the web server
      offering the fastest and most reliable service.

                                       45
<PAGE>

    . Site Replicator. Site Replicator enhances web site availability by
      mirroring web site content between multiple servers. Site Replicator
      copies new files, scripts and web images from the primary server to
      the other servers within its defined group. Site Replicator is a
      flexible web data replication tool, using efficient algorithms and
      intelligent data transfer techniques to minimize overhead and ensure
      that content on all web servers is synchronized.

    . Site Accelerator. Site Accelerator replicates web site content on
      servers throughout our Internet backbone and brings this content
      geographically closer to our users, a process known as caching. This
      process reduces web page load times. Because this service is
      performed in our network, our customers receive the benefits of
      caching without any capital investment. Site Accelerator splits the
      task of serving content between the cache servers in our network and
      the dedicated web site servers. When the content is moved to our
      cache servers, the dedicated web site servers are freed up,
      permitting more users and more transactions without sacrificing
      performance from the perspective of the end user.

   Value-added e-Business Services. As enterprises and service providers
continue to use the Internet as a business-critical tool, we believe they will
increasingly demand a wider range of e-business services to ensure security,
enhance productivity, reduce costs and improve service reliability and
scalability. Today, we offer a range of value-added e-business services,
including:

  . Virtual Private Networks. With our virtual private network service, we
    enable an enterprise and its employees, customers, suppliers and business
    partners to securely send and receive information to and from each other
    via encrypted dial-up, dedicated, digital subscriber line or cable-modem
    Internet connections. Our VPN Advantage SM service is a managed virtual
    private network service that makes it possible to communicate securely
    over our Internet backbone and over the Internet from virtually anywhere
    in the world. With VPN Advantage, our customers benefit from the
    capabilities of a large, shared IP-based network infrastructure while
    maintaining the look and feel of their own private corporate network.

  . Managed Security Services. Our managed security services are scalable and
    can be customized to our customers' needs and provide a high level of
    protection for their corporate networks. Our managed security services
    include monitoring the network perimeters of our enterprise customers, 24
    hours a day, seven days a week, and use of firewall management,
    maintenance and proactive response techniques to ensure the security of
    access points into their computing infrastructure. Our Site Patrol SM for
    FireWall-1(R) and our Security Advantage SM are Internet security
    services that help to significantly reduce exposure to Internet security
    threats and firewall breaches. In addition, we offer a vulnerability
    assessment service, Site Scan SM, that helps enterprises strengthen their
    network perimeter security by periodically testing for potential
    weaknesses and generating recommendations for correcting them.

  . Voice-over-Internet Protocol. Through our suite of voice-over-IP
    services, including International VoIP Direct SM and ESP Direct SM, we
    offer low-cost, high-quality voice-over-IP network transport to Internet
    service providers, Internet telephony service providers, enhanced service
    providers and telecommunications companies providing voice-over-IP
    services to their customers. We seek to provide our customers with
    accelerated time-to-market for their customers through innovative,
    enhanced solutions enabling voice services such as personal computer-to-
    phone and personal computer-to-personal computer.

   Transport. Our transport services are generally purchased by
telecommunications carriers and Internet service providers requiring additional
capacity. In delivering these services, we provide a single point of contact
for planning, ordering, installing, billing, maintaining and managing the
transport services of our customers. Our transport services, which accounted
for 12% of our total revenues in 1999, include:

  . ATM Service. Our asynchronous transfer mode, or ATM, transport service, a
    form of high speed data transfer, is targeted primarily at carriers and
    Internet service providers with high bandwidth voice, video and data
    transmission requirements. We provide ATM connections between one or more

                                       46
<PAGE>

    locations. Our ATM transport services provide logical permanent virtual
    connections, thereby supporting applications that send information at a
    constant or variable bit rate. We offer a wide range of speeds at one
    megabit per second increments and match the application needs to the
    desired amount of bandwidth.

  . Private Line Service. Our private line service provides dedicated point-
    to-point transport services through non-switched, non-usage sensitive
    dedicated facilities. Our private line service is supported over our
    dedicated Synchronous Optical Network, or SONET, facilities, which
    results in a highly reliable network. These services are comprised of
    bandwidth delivered in units of: (1) DS-3, which is capable of
    transmitting data at 44.736 megabits per second; (2) OC-3, which is
    capable of transmitting data at 155.520 megabits per second; (3) OC-12,
    which is capable of transmitting data at 622.080 megabits per second; and
    (4) OC-48, which is capable of transmitting data at 2.488 gigabits per
    second.

  . Network Collocation Services. Our collocation services provide our
    customers with a physical location to collocate communications equipment
    at our points of presence. This service allows our service provider
    customers to expand their market areas without extensive recurring real
    estate charges, build-out fees and overhead costs.

Our Network

   We operate a state-of-the-art, facilities-based global fiber optic network
designed specifically for IP technology. We own the core components of our
network infrastructure in the United States through indefeasible rights of use,
or IRUs, for the underlying fiber optic cable. Within the United States we also
lease capacity from third parties to provide service to our customers. We
estimate that a majority of our traffic is currently transmitted over this
leased capacity. We are in the process of transitioning traffic from leased
capacity to our network infrastructure and expect that over 80% of our traffic
will travel over our owned network by the end of 2001. We also own undersea
capacity through IRUs and lease capacity internationally. Our current network
infrastructure consists of:

  . over 17,500 route miles of owned inter-city fiber cable in the United
    States that passes through the largest 100 metropolitan service areas and
    substantial additional leased capacity;

  . undersea capacity to Europe via Atlantic Crossing-1 and to Asia via TPC-
    5;

  . over 70 dedicated points of presence in the United States through which
    high speed dedicated Internet access is provisioned;

  . over 800 local points of presence for dial-up access in the United States
    and, through our reseller relationship with iPass, an additional 1,500
    local access points of presence in more than 150 other countries;

  . nine points of presence in international markets, including Amsterdam,
    Dublin, Frankfurt, London (2), Milan, Paris, Sydney and Tokyo, with the
    ability to provide service from over 300 additional points of presence in
    over 60 countries though leased facilities; and

  . eight data centers located in the United States and one each in the
    United Kingdom and Japan.

   We plan to substantially expand our network infrastructure, both
domestically and internationally. Through the end of 2001, we plan to:

  . extend our coverage by deploying an additional 4,500 route miles of fiber
    cable serving approximately 120 additional metropolitan service areas in
    the United States and build local fiber rings in major metropolitan
    service areas in the United States;

  . utilize additional international undersea capacity to: (1) Europe via
    TAT-14 and FLAG Atlantic; (2) Latin America via Americas II; (3) the
    Caribbean via ARCOS-1; and (4) Asia via Japan-US cable network;

                                       47
<PAGE>


  . expand our network capacity in the United States to the equivalent of 10
    layers of 10 gigabit capacity each;

  . add more than 200 additional dedicated points of presence for access in
    the United States;

  . add an additional 11 points of presence in key international markets;

  . add approximately 800,000 additional modems to our North American dial-up
    infrastructure and expand our coverage to an additional 300 local markets
    in North America;

  . expand our broadband coverage to 80 metropolitan service areas and
    surrounding cities in the United States; and

  . build seven additional data centers in key locations worldwide, which
    will increase our existing capacity by approximately 1.2 million square
    feet.

   As we expand our network infrastructure, both domestically and
internationally, we intend to primarily build and own our facilities rather
than lease them from other facilities-based providers. In addition, we have
taken the flexible approach of utilizing multiple fiber providers to ensure
higher reliability, quicker deployment of new technology and faster
provisioning for our customers. Our network infrastructure has the following
characteristics:

   High Performance, Reliability and Quality. The geographic reach and state-
of-the-art nature of our network enhance our ability to provide a high quality
user experience. We have incorporated a variety of technologies in our network
to ensure high performance and reliable transmission. These technologies
include OC-192, which is capable of transmitting data at 10 gigabits per
second, and SONET transmission equipment employing self-healing protection
switching. These technologies, combined with our ring-based architecture,
increase network reliability and minimize the risk of service outages. In the
event of a failure in any segment of our network infrastructure, traffic is
automatically rerouted across different fiber strands with virtually no
interruption in service. Additionally, our network infrastructure makes
extensive use of railroad rights-of-way that typically offer greater protection
for the fiber than fiber deployed over other rights-of-way such as highways,
telephone poles or overhead power transmission.

   Capacity on Demand. We currently have an indefeasible right to use over
17,500 route miles of fiber in the United States, with virtually all of these
fiber route miles having 24 separate strands. These fiber route miles, which
form the core of our network infrastructure in the United States, were
operational at the end of 1999. The majority of the fiber deployed in our
network infrastructure is state-of-the-art Lucent True Wave(R) fiber that
supports multiple wavelengths, each running at 10 gigabits per second, thus
allowing for more capacity on a single fiber strand. Our fiber network,
combined with our network design, enables us to take advantage of the most
recent advances in optical electronic transmission equipment. For example, we
generally are using only four of our existing 24 strands of fiber, each of
which supports up to eight wavelengths per fiber at 10 gigabits per second data
transmission using current generation optical electronic transmission
equipment. However, as optical electronic transmission equipment providing 16,
32, 50 or even higher numbers of wavelengths per fiber becomes commercially
available, we plan to deploy this equipment as needed on unused fiber strands
to expand the capacity of our network infrastructure. With the advanced nature
of our fiber network and the advances in optical electronic transmission
equipment, we believe we will have sufficient capacity on our existing fiber in
the United States for the foreseeable future. In addition to our owned
facilities, we supplement our existing route miles with leased capacity from
other providers.

   Advanced Network Architectures. We believe that owning our network allows us
to implement new network architectures as they become technologically feasible.
For example, IP over dense wave division multiplexing, which is an optical
technology that increases the amount of data that can be transmitted over a
single fiber by dividing that fiber into multiple lightpaths or wavelengths,
will eliminate the need for the SONET network layer by relying on IP routers
and the dense wave division multiplexing equipment to perform the re-routing
that SONET currently performs. Furthermore, advanced optical networking
transmission

                                       48
<PAGE>

equipment will enable traffic to be switched and routed without being converted
to an electrical signal first. We believe our engineering and architectural
expertise will enable us to quickly deploy these new architectures and
technologies, thereby reducing the complexity of data systems, increasing
flexibility and reducing costs.

   Flexible Platform for Multiple Services. Our network has been specifically
designed for IP and can carry any form of packet data, including voice, video
and traditional data services. While many carriers and service providers use
multiple networks and platforms to deliver these distinct services, our IP-
optimized network provides a single platform that simplifies network
management, customer support and service delivery. In addition, ownership of
our facilities enables us to deploy new or enhanced services more quickly. For
example, we designed and deployed one of the first architectures to transmit
real-time voice and data packets with reliability and performance substantially
equivalent to the public switched telephone network. Moreover, our architecture
allows for rapid scalability of capacity, quick geographic expansion and cost-
efficient implementation of new services and features.

Our Data Centers

   We currently operate 10 data centers that have been specifically designed
for managed web and application hosting services and high capacity connectivity
to our network. We have eight data centers in the United States, located in
Palo Alto, California; San Jose, California; Los Angeles, California; Phoenix,
Arizona; Chicago, Illinois; Cambridge, Massachusetts; Washington, D.C.; and New
York, New York. We also have one data center in each of Leeds, England, and
Tokyo, Japan.

   Our data centers are strategically located in the same building, or in close
proximity to, network access points, and all are directly connected to our
Internet backbone. Our data centers are technologically advanced facilities
with:

  . redundant, high speed connectivity to the Internet;

  . uninterruptible power supplies;

  . back-up generators;

  . fire suppression;

  . computer floors;

  . separate cooling zones;

  . seismically braced racks; and

  . high levels of physical and network security.

   Our highly trained staff monitors these systems 24 hours a day and seven
days a week. By the end of 2001, we plan to add seven data centers, adding
approximately 1.2 million square feet of additional capacity. Each of these new
data centers will be directly connected to our network and will be designed
specifically for mission-critical servers with complete redundancy of all
support systems. We expect these seven new data centers will be located in: Los
Angeles, California; Mountain View, California; Atlanta, Georgia; Cambridge,
Massachusetts; Carteret, New Jersey; Dallas, Texas; and Chantilly, Virginia.

Our International Operations

   We provide global coverage for our international customers. Today, we lease
our network facilities in international markets, including back haul services
from over 300 local points of presence in 60 countries and a SONET fiber ring
connecting London, Paris, Frankfurt and Amsterdam, which is capable of
transmitting data at 155.520 megabits per second. We are able to provide
dedicated access services in more than 60 countries and enable global dial-up
access service in more than 150 countries. We provide web hosting services out
of our data centers in the United Kingdom and Japan and we have the capability
to provide managed security and virtual private network services in over 39
countries. We have nine points of presence in international markets, including:
Amsterdam; Dublin; Frankfurt; London (2); Milan; Paris; Sydney; and Tokyo. All
of our international points of presence are capable of accepting voice-over-IP
traffic for delivery in the United States.

   By the end of 2000, we plan to add 11 additional points of presence in the
following locations: Manchester; Madrid; Stockholm; Dusseldorf; Hamburg; Hong
Kong; Buenos Aires; Sao Paulo; Rio de Janeiro; San Juan; and Mexico City.


   By the end of 2000, we also plan to deploy one of the first OC-48 fiber
rings in Europe employing IP over dense wave division multiplexing. We believe
this fiber ring network connecting London, Amsterdam, Frankfurt and Paris will
dramatically improve our ability to provide high-end data services and is
required to meet our rapidly growing traffic in Europe.

   In terms of trans-oceanic capacity, over the past two years we have entered
into a number of agreements for indefeasible rights of use to cable systems
that are either deployed or in the process of deployment. The following table
details our current and planned international cable capacity. The expected
dates of deployment represent approximate time frames in which we believe our
capacity on this cable will become operational. These dates are, to a large
extent, beyond our control and deployment may occur significantly later than we
expect.

Research and Development

   We believe that the task of building an Internet infrastructure services
business is primarily one of integrating third-party systems, technologies,
communications equipment, software and services to provide reliable, highly
scalable and cost-effective Internet infrastructure services. Therefore, we
generally use commercially available equipment. Our 30 years of IP and
networking experience and expertise not only enables us to assess the
technology and quality of potential vendors and to assist them in making their
products more responsive to the needs of our customers.

   We continually monitor research developments in the various industries
supporting our business. We work closely with the engineering groups of our
existing vendors, technology partners, innovative start-up companies and
complementary service providers to incorporate advanced technology, features
and services. For example, we have worked closely with Cisco Systems, one of
our primary suppliers, to develop new equipment and have been regular
participants in its Technical Advisory Group. Through this and other
cooperative programs, we strive to ensure that new hardware designs address the
evolving requirements of our business and those of our customers.

   In addition, we plan to work with innovative start-up companies to assist
them in developing and implementing advanced technologies and converting these
technologies into market-ready products and services. A key component of our
strategy will be to develop strategic relationships with those start-ups that
have technology or services that can help us expedite the execution of our
business plan. The strategic nature of these relationships could take the form
of acquisitions, technology transfers, equity investments or joint product
development.

Our Customers

   We primarily target enterprises and service providers. We have established a
large and diversified base of enterprise customers in a wide range of
industries, including financial services, manufacturing, media and publishing,
consulting services and high technology. As of March 31, 2000, we had
approximately 5,000 enterprise customers, the majority of which were located in
the United States. The following is a representative list of our enterprise
customers.

Our Relationship With America Online

   We have supplied managed, dial-up access services in the United States to
America Online since 1995. During the year ended December 31, 1999, America
Online accounted for approximately 52% of our total revenues. We entered into a
new agreement with America Online effective as of December 31, 1999, pursuant
to which America Online has agreed to purchase additional dial-up Internet
access services from us for a seven-year term through December 31, 2006. Under
the new agreement, America Online has also agreed to purchase managed digital
subscriber line and other broadband network access services from us for a five-
year term through December 31, 2004. The components and resources used to
provide dial-up access and broadband connections to our network backbone for
America Online are dedicated to them and may not be used by us to service other
customers. In addition, our Columbia, Maryland network operations center is
dedicated to servicing America Online.

   Dial-Up Services. Under the new agreement, America Online has committed to
purchase from us agreed upon minimum quantities of dial-up network access
services as measured by the number of dial-up access ports, or modems,
available for America Online customers. America Online has agreed to increase
the number of dial-up access ports to be managed by us through June 2002,
subject to the terms and conditions of the agreement. America Online pays us a
fixed monthly fee for each activated dial-up access port managed by us for it.
Under the agreement, the monthly per access port fee to which we are entitled
will be reduced at specified intervals over the term of the agreement. In
addition, we have agreed, subject to limitations, that if we offer a third
party better pricing for comparable dial-up access services than that paid by
America Online, America Online may gain the benefit of this better pricing.

   At specified times during the course of the new agreement, America Online
has the right to seek a reduction in the fees paid to us for access ports based
on the then prevailing market prices for comparable dial-up access services in
the manner described in the new agreement. If we do not agree to reduce the
fees we charge to America Online for the applicable dial-up access ports to the
market price, America Online may, subject to advance notice and other
limitations, terminate future dial-up service commitments to us and
decommission an equal number of its existing dial-up access ports with us.
Similarly, America Online may reduce its dial-up service commitments in the
event we fail to meet monthly or geographic delivery targets.

   Beginning January 1, 2003, America Online may, subject to advance notice and
other limitations, decommission dial-up access ports managed by us in
proportion to their decommissioning of dial-up access ports provided by other
vendors. We are required to maintain a dedicated network operations center to
service the portions of our network dedicated to America Online.

   Broadband Services. Under the agreement, we also provide broadband services
to America Online in connection with their digital subscriber line service
offerings. America Online also has agreed to purchase additional network
services from us in connection with its other broadband service offerings,
including cable modem, wireless and satellite, as they offer additional
broadband access options to their customers. America Online has committed to
purchase from us the network services necessary to serve specified percentages
of

                                       52
<PAGE>

their digital subscriber line and other broadband customers. In connection with
providing digital subscriber line service to an America Online customer,
America Online is responsible for providing its customers with the local access
circuit and we are responsible for the interconnection of that circuit to our
backbone, transmission of the traffic to America Online and the monitoring,
management and control of the network.

   We receive a specified monthly fee for each America Online digital
subscriber line and other broadband customer for whom we provide network
services. Under the agreement, America Online pays us monthly fees based on the
number of America Online broadband customers that are connected to our network,
which fees are subject to agreed upon reductions as the number of America
Online digital subscriber line and other broadband customers for whom we are
providing services increases. In addition, we have also agreed to extend
broadband network services. At specified times during the course of the new
agreement, America Online has the right to seek a reduction in the fee paid to
us for broadband backhaul services based on then prevailing market prices for
comparable broadband backhaul services. If we do not agree to reduce our fees
to America Online for broadband network services to the market price in the
manner described in the new agreement, America Online may, subject to advance
notice and other limitations, terminate future broadband service purchase
commitments to us and terminate existing broadband service. America Online may
also terminate future broadband service purchase commitments in the event we
fail to deliver services to a new local access and transport area within a
specified period.

   General. In providing America Online services under the agreement, we are
obligated to comply with specified minimum service levels. Either party may
terminate the agreement in the event the other party commits a material breach
which is not cured within 30 days after notice of the breach. In addition,
America Online has the right to terminate the agreement in the event of:

  . repeated material breaches by us even if cured;

  . a violation of the most favored customer pricing provisions;

  . a total or near total outage of any of the services provided by us that,
    even if lasting fewer than 30 days, is widespread and prolonged;

  . our inability to meet our service level commitments or to expand service
    availability as required under the agreement; and

  . a change in control of us other than changes in control resulting from or
    arising out of the closing of the proposed merger of GTE and Bell
    Atlantic.

   We are also obligated to provide America Online assistance in the 12 months
following any termination of the agreement to ensure a smooth transition of
services. The agreement provides America Online with a right of first refusal
with respect to the sale of our dial-up network access business.

   Under a separate agreement, we have agreed to provide dial-up network access
services to America Online in Japan. This agreement includes similar provisions
to those described above regarding minimum purchase requirements on the part of
America Online Japan, market pricing adjustments, service level requirements
and termination provisions.

Operations and Customer Support

   We believe that a high level of operational and customer support is critical
to our success in attracting and retaining enterprise and service provider
customers. We provide superior customer support by understanding the evolving
and often complex technical requirements and business objectives of our
customers. We assist our customers by initially assembling design teams
comprised of product specialists from all relevant areas of our organization,
including Internet access, web hosting and security. These design teams work
closely with our customers from the very beginning of the relationship to
properly identify their Internet infrastructure requirements and design
appropriate solutions. We also assign a project manager to this team when a
customer is prepared to implement its solution. Our design teams can range from
a small group for single service

                                       53
<PAGE>

solutions to a dedicated multi-discipline team for complex solutions. We also
assign an implementation engineer to coordinate all of our activities with a
customer. Our implementation engineers assist customers in developing
operational processes and databases for use within their internal support
environment after installation.

   We provide toll-free phone access, as well as e-mail or facsimile access, to
our customer support centers. In addition, our web-enabled customer service
tools allow our customers to track order and service status and request
upgrades online. In addition, we have event management teams available 24 hours
a day, seven days a week, to work with the appropriate organizations in the
event of any major Internet-wide event that disrupts service. In these
circumstances, we also utilize our automated emergency broadcast capability to
quickly reach our customer by e-mail, telephone, facsimile or pager.

   We provide operational support for all services 24 hours a day, seven days a
week. We also have network engineers and operational support agreements with
our vendors to provide us with support 24 hours a day, seven days a week.
Currently our primary Network Operations Center is located in our Burlington,
Massachusetts headquarters facility. This Network Operations Center is
supported by redundant power served from separate sources, extensive failover
battery backup and dual, on premises power generation stations. We plan to
relocate our primary Network Operations Center from Burlington, Massachusetts
to our new Woburn, Massachusetts campus that is currently under construction.
In addition, we have a Network Operations Center in Columbia, Maryland and are
finalizing plans for a new Network Operations Center in the Dallas, Texas area
to replace a facility we currently share with GTE. Our Columbia, Maryland
Network Operations Center is dedicated to servicing America Online. We also
have Operations Support Centers in Cambridge, Massachusetts and Chantilly,
Virginia. Our centers can perform disaster back-up for other centers. Our data
centers are designed with these same commitments to availability, and we
guarantee these capabilities with service level guarantees.

Sales and Marketing

   Within the United States, we rely primarily on a direct sales force. This
direct sales force focuses on U.S.-based enterprises and service providers with
domestic and international service requirements. Our sales force within the
United States generally works with the managers of the marketing, sales or
finance departments, as well as with information technology officers within the
enterprise. In addition, through our eP@rtners program, we have formed
alliances with leading web integrators, e-business consultants, interactive
agencies and other technology providers, which increases our access to
potential service provider and enterprise customers. Our current partners in
this program include:

<TABLE>
<S>  <C>

  . Agency.com                                    . IBM

  . Cambridge Technology Partners                 . Lante

  . Cisco Systems                                 . Microsoft

  . Ernst & Young                                 . Nortel Networks

  . Hewlett-Packard                               . Sapient
</TABLE>


These alliances enable us to provide comprehensive e-business solutions and
also serve as a valuable, cost-effective channel for marketing our services. We
also plan to expand our existing reseller relationships to significantly
enhance our distribution capabilities.

   Internationally, we have both a direct sales force and a channel partner
program, which we call our Net.Alliance program. Our international direct sales
force focuses primarily on the international service provider segment, while
our Net.Alliance partners are our primary channel to multinational companies
based outside of the United States. Many of our Net.Alliance partners are both
customers and resellers of our services. This channel gives us distribution
capabilities in over 14 countries globally. Our current partners in this
program include Energis in the United Kingdom and Tiscali and I.NET in Italy.

                                       54
<PAGE>

   All of our sales representatives participate in extensive technical and
consultative sales training programs that we believe enable them to better
comprehend, respond to and resolve the complex networking problems of our
customers. As of March 31, 2000, we had a direct sales force of over 350
people.

   We only recently changed our name to Genuity. To be successful, we must
establish and strengthen our brand recognition. We intend to incur significant
expenses to promote our brand. Our marketing organization is responsible for
developing the strength and awareness of the Genuity brand on a local, national
and international basis. We intend to build brand awareness through a variety
of methods, including radio, print advertising in trade journals and special-
interest publications and our web site. In addition, we also employ public
relations personnel in-house and work with an outside public relations agency
to provide broad coverage in the Internet and computer networking fields. To a
limited extent, we also directly market our services at seminars and trade
shows such as Internet World, ISPCon, COMnet, CeBit and various Gartner Group
information technology conferences.

Competition

   The market for Internet infrastructure services is extremely competitive and
subject to rapid technological change. We expect to encounter increased
competition in the future as a result of increased consolidation and
development of strategic alliances in the industry. In addition, we will
compete with foreign service providers as we expand internationally and as
these service providers increasingly compete in the United States market. Our
principal competitors in the Internet infrastructure services market may be
divided into Internet infrastructure service providers and niche players
offering services competitive with one or more of our services.

   Internet Infrastructure Service Providers. We were recently recognized by
Giga Information Group as one of a limited number of Tier 1 Internet backbone
providers that offer managed Internet infrastructure services. Accordingly, we
believe our primary competitors are those Internet infrastructure service
providers that offer a similar breadth of services and possess the on-network
users and content to offer their customers connectivity to virtually all
addresses on the Internet, either through their Internet backbone or through
high speed private peering relationships that permit them to have direct, cost-
free exchange of traffic with a significant number of carriers and other
Internet service providers. These competitors include UUNET Technologies, a
subsidiary of MCI WorldCom, AT&T, Cable & Wireless and Sprint. UUNET has
substantially greater market share than we do, and some of the others also have
greater market share than we do. UUNET is a competitor for America Online's
access requirements and is reported to provide a substantial portion of those
requirements. In addition, MCI WorldCom and Sprint have announced a proposed
merger. We believe this proposed merger would substantially increase the market
share and competitive position of UUNET, even if it were required to divest
itself of portions of its Internet backbone as a condition to the merger. Some
of these competitors also are able to bundle their Internet service offerings
with non-Internet data services, such as frame relay, and traditional voice
services, such as local and long distance, thereby reducing the price of their
services relative to ours. We may not be able to offset the effects of any
price reductions because we only offer IP-based services. We also compete with
an increasing number of Internet service providers that have a significant
regional, national or international presence but do not offer as broad a range
of services or possess fewer users and less on-network content than the
infrastructure service providers listed above. These competitors include, among
others, Level 3 Communications, Qwest Communications, KPNQwest, Deutsche
Telekom, PSINet, Verio Communications and Williams Communications Group. As a
result of the increase in the number of competitors and the vertical and
horizontal integration that is occurring in this industry, we currently
encounter and expect to continue to encounter significant competition, which
could force us to, among other things, reduce our rates and invest more heavily
in infrastructure.

   We believe we compete with these competitors primarily on the basis of
quality and quantity of on-network users and content, breadth of service
offerings, geographic reach and quality of network infrastructure, capacity,
quality of service and price. While we believe that our network infrastructure,
comprehensive suite of services and expertise in designing, developing and
implementing managed Internet infrastructure solutions distinguish us

                                       55
<PAGE>

from our competitors, many of our existing and potential competitors have
greater financial and other resources, more customers, a larger installed
network infrastructure, greater market recognition and more established
relationships and alliances in the industry. As a result, these competitors may
be able to develop and expand their network infrastructure and service
offerings more quickly, adapt more swiftly to new or emerging technologies and
changes in customer demands, devote greater resources to the marketing and sale
of their offerings, pursue acquisition and other opportunities more readily and
adopt more aggressive pricing policies.

   Niche Players. There are numerous competitors that service generally one or
a small number of the specific Internet infrastructure requirements of
enterprise customers. These competitors include, among others:

  .  web-hosting companies, such as Digex and Exodus Communications;

  .  broadband Internet access providers such as Covad Communications and
     Rhythms NetConnections, both of which focus on digital subscriber line
     services;

  .  providers of security and virtual private networks, such as Pilot
     Network Services; and

  .  transport service providers, such as Level 3 Communications, Qwest
     Communications and Williams Communications Group.

   We believe that there are relatively few barriers to entry in these markets.
We compete with these niche players on the basis of technical expertise,
quality of service, reliability and price.

   There are numerous other companies from a variety of industries that have
also focused on our target market. For example, many of the major cable
companies have begun offering, or are exploring the possibility of offering,
Internet access through their current networks to include Internet access
capabilities. Direct broadcast satellite and wireless communications providers
have also entered the Internet access market with various wireless and
satellite-based service technologies. We believe that direct broadcast
satellite and wireless communications providers have also entered the Internet
access market.

   As we continue to expand our operations in markets outside the United
States, we will also encounter new competitors and competitive environments.
Our foreign competitors may enjoy a government-sponsored monopoly on
telecommunications services essential to our business, and will generally have
a better understanding of their local industry and longer working relationships
with local infrastructure providers.

Employees

   As of March 31, 2000, we had a total of 3,557 employees, of which 1,263 were
in customer service and support, 866 were in engineering, 761 were in sales and
marketing, 345 were in information technology and 322 were in finance and
administration. Our employees are not represented by any collective bargaining
agreement, and we believe that relations with our employees are good.

Real Estate Facilities

   We currently occupy our headquarters and primary Network Operations Center
in Burlington, Massachusetts under a lease that expires in 2009. This lease
includes renewal options for two three-year periods. We are constructing a two-
building campus in Woburn, Massachusetts that is scheduled for completion in
the next 12 months. We plan to move our corporate headquarters operations,
including executive staff, finance, human resources and information technology
organizations, to our Woburn, Massachusetts campus. We anticipate that our
network operations organization, including our primary Network Operations
Center, also will relocate from Burlington, Massachusetts to Woburn,
Massachusetts. We intend to retain our Burlington, Massachusetts facility to
house our engineering, sales and marketing and service line organizations. We
lease space for our other Network Operating Center in Columbia, Maryland and
are finalizing plans for a new Network Operations Center in the Dallas, Texas
area to replace a facility we currently share with GTE.

Proprietary Rights

   We rely on a combination of patent, copyright, trademark and trade secret
laws and contractual restrictions to establish and protect our technology. We
own, either exclusively or jointly, an interest in nearly 200 inventions that
are the subject of patents, patent applications or patent disclosures. These
legal protections provide only limited protection. Further, the market for
Internet infrastructure services is subject to rapid technological change.
Accordingly, while we intend to continue to protect our proprietary rights
where appropriate, we believe that our success in maintaining a technology
leadership position is more dependent on the technical expertise and innovative
abilities of our personnel than on these legal protections.

   Despite our efforts to protect our proprietary technology, we cannot assure
you that the steps taken by us will be adequate to prevent misappropriation of
our technology or that our competitors will not independently develop
technologies that are substantially equivalent or superior to our technology.
The laws of many countries do not protect our proprietary technology to as
great an extent as do the laws of the United States. We may need to resort to
litigation in the future to enforce our intellectual property rights, to
protect our trade secrets, to determine the validity and scope of the
proprietary rights of others or to defend against claims of invalidity. We are
also subject to the risk of adverse claims and litigation alleging infringement
of the intellectual property rights of others. Any resulting litigation could
result in substantial costs and diversion of management and other resources and
could have a material adverse effect on our business and financial condition.

   GTE has granted the exclusive right to our existing trademarks and
proprietary technology to TELUS Corporation for use solely in Canada for the
provision of telecommunications services, including Internet services. We rely
on TELUS to provide, in conjunction with us, some Internet services in Canada.

Regulatory Matters

   The following summarizes regulatory developments and legislation that we
believe are currently material to us. It does not describe all present and
proposed federal, state, local and foreign regulation and legislation affecting
the telecommunications industry.

   Our existing and planned Internet operations are not actively regulated by
the Federal Communications Commission or any other government agency of the
United States at the present time, other than regulations that apply to
businesses generally. However, one of our wholly owned subsidiaries is
classified as an "interexchange carrier" and provides primarily private-line
data services. As a result, this subsidiary is regulated as a
telecommunications carrier and is subject to the requirements described below
under "Telecommunications Services". Furthermore, the regulations governing the
telecommunications industry generally are often subject to regulatory,
judicial, or legislative modification and are in a state of flux at the present
time. Some private parties and regulators have called the current regulatory
status of various Internet service offerings into question.

   We cannot predict the actions of the regulatory authorities that have
jurisdiction in this area or whether any of these authorities will attempt to
impose new regulations on Internet services or expand their interpretations of
existing regulations to make them apply directly to Internet services.
Accordingly, we do not know whether current or future regulations could have a
material adverse effect on us. If any regulatory authority imposes new
regulations or expands their interpretations of existing regulations to make
them applicable to Internet operations, some or all of the following rules may
be applied to those operations. However, if new regulations are imposed on our
industry, or existing regulations are expanded to cover our industry, these
regulations will almost certainly also apply to all similarly situated parties
offering comparable services, including our competitors.

 Federal Telecommunications Regulation

   Federal regulations have undergone major changes in the last four years as
the result of the enactment of the Telecommunications Act of 1996. The
Telecommunications Act is the most comprehensive reform of the
telecommunications law in the United States since the Communications Act was
enacted in 1934. For example,

                                       57
<PAGE>

the Telecommunications Act imposes interconnection and access requirements on
telecommunications carriers and on all local exchange carriers, including
incumbent local exchange carriers and competitive local exchange carriers.

   Under the current regulatory regime, communications related services are
generally classified into one of the following three definitional categories:

  .information services;

  .private carrier services; and

  .telecommunications services or common carriage.

Because the boundaries between these categories are neither precise nor well-
fixed, and the industry is so dynamic, we cannot predict where particular
services will be classified, now or in the future. The regulations associated
with each type of classification are described below.

   Information Services. Except for the provision of underlying basic
transmission capability, Internet services have generally been considered to be
"information services". Under current law, operators of information services
are exempt from regulation by the FCC, but operators of telecommunications
services are not similarly exempt. However, the FCC continues to review its
regulatory position on the usage of the basic network and communications
facilities used by Internet service providers. Whether it will assert
regulatory authority over the Internet, and the level of any asserted
authority, is a pending issue. While the FCC has determined in an April 1998
report to Congress that Internet access providers should not be treated as
telecommunications carriers and therefore should not be regulated, it is
expected that the status of various types of Internet service providers will
continue to be uncertain.

   In the same report, the FCC also concluded that some of the services
currently offered over the Internet, such as phone-to-phone IP telephone
services, may be functionally indistinguishable from traditional
telecommunications service offerings, and that their non-regulated status may
have to be reexamined. The report also indicated that the FCC would determine
on a case-by-case basis whether to subject IP telephone service providers to
regulation, including whether to require them to contribute financially to
universal service support mechanisms, which could also subject these services
to other forms of regulation. The FCC has also stated that it may require
Internet service providers that use their own transmission facilities to
provide Internet access services to contribute to universal service mechanisms,
and has previously considered and rejected the possibility of regulating
Internet backbone peering arrangements, although that issue remains subject to
further review.

   Private Carrier Services. The offering of private carrier services typically
entails the offering of telecommunications to a limited class of users on the
basis of individually negotiated terms and conditions. As a result, they do not
meet the definition of a telecommunications service under the
Telecommunications Act. These private carriers are generally unregulated by the
FCC, but are subject to regulation for intrastate offerings in some states and
incur universal service payment obligations, discussed below, based on their
gross revenues from end users. These private carriers may also be subject to
access charges if interconnected to local exchange facilities.

   Telecommunications Services. A significant amount of regulation applies to
providers of telecommunications services. The Communications Act defines
telecommunications carriers as entities offering telecommunications services,
which are in turn defined as the offering of telecommunications for a fee,
directly to the public or to classes of users so as to be effectively available
directly to the public. The law does not distinguish on the basis of the
facilities used to provide these services. "Telecommunications" is defined as
the transmission, between or among points specified by the user, of information
of the user's choosing, without change in the form or content of the
information as sent and received. The FCC has found that the definition of
"telecommunications carrier" is essentially the same as the definition of
"common carrier". Telecommunications carriers are subject to regulatory
requirements that may impose substantial administrative and other burdens on
their operations.

                                       58
<PAGE>


   The FCC imposes regulations on some common carriers that have been found by
the FCC to have some degree of market power, otherwise known as dominant
carriers. The FCC imposes less regulation on other common carriers, which have
been found not to have market power, otherwise known as "non-dominant
carriers". A subsidiary of GTE is classified as a non-dominant carrier. These
non-dominant carriers do not need express prior authorization to provide
domestic services and can file tariffs on one day's notice. The FCC requires
common carriers to obtain a formal authorization to construct and operate
telecommunications facilities and to provide or resell telecommunications
services between the United States and international points. The FCC also
regulates carrier exits from markets.

   General Obligations. All telecommunications carriers are subject to the
complaint process and rules and regulations of the FCC, as well as various
other requirements set out in Title II of the Communications Act of 1934, as
amended. In addition, telecommunications carriers have general obligations,
including the following:

  . not to charge unreasonable rates or engage in unreasonable practices;

  . to provide service on reasonable request;

  . not to unreasonably discriminate in their service offerings;

  . to comply with reporting requirements;

  . to offer customer premises equipment for sale on an unbundled basis to
    the extent that it is offered;

  . to allow resale of their services in some circumstances; and

  . to restrict their use of customer information.

   In addition, telecommunications carriers are subject to further regulatory
requirements, some of which are discussed in greater detail below.
Telecommunications carriers must also pay regulatory fees associated with
filing license applications and other documents with the FCC.

   Interconnection Obligations. All telecommunications carriers have the basic
duty to interconnect and interoperate, either directly or indirectly, with the
facilities of other telecommunications carriers.

   Section 214 Authorizations. Common carriers are obligated to obtain, under
Section 214 of the Communications Act, authorization from the FCC to provide
services between the United States and other countries, and to disclose, among
other things, the extent to which they are owned or controlled by foreign
entities. The compliance with these regulatory requirements imposes
administrative and other burdens on these carriers.

   Tariffs and Pricing Requirements. The FCC has eliminated the requirements
that non-dominant interstate interexchange carriers maintain tariffs on file
with the FCC for domestic interstate services. One of our wholly owned
subsidiaries is a non-dominant interstate interexchange carrier. Under the
rules of the FCC, after a transition period currently scheduled to expire on
January 31, 2001, relationships between interstate carriers and their customers
would be set by contract. At that point, the FCC would no longer permit the use
of tariffs for interstate, domestic interexchange services. Competitive local
exchange carriers do not have to file tariffs for their exchange access
services, but may if they choose to do so. The FCC is considering whether to
impose mandatory detariffing on them as well. There has been no proposal to
detariff international services.

   Customer Proprietary Network Information. The use by a telecommunications
carrier of customer proprietary network information, which generally includes
any information regarding a subscriber's use of a telecommunications service
obtained by a carrier solely by virtue of the carrier-customer relationship, is
subject to statutory restrictions. This customer proprietary network
information does not include a subscriber's name, telephone number and address,
if that information is published or accepted for publication in any directory
format. A telecommunications carrier may use a customer's proprietary network
information only to market a service that is "necessary to, or used in" the
provision of a service that the carrier already provides to the

                                       59
<PAGE>


customer, unless it receives the customer's prior oral or written consent to
use that information to market other services. The initial rules of the FCC
regarding customer proprietary network information have been struck down in the
courts and other rules adopted for reconsideration have not gone into effect,
leaving the current state of the customer proprietary network information
requirements uncertain. The FCC is expected to initiate further proceedings to
address this issue. These rules, either as adopted or as modified, may impede
the ability of a telecommunications carrier to effectively market integrated
packages of services and to expand existing customers' use of its services.

   Universal Service. The FCC has recently expanded aid to schools and
libraries and extensively revamped the support structure for high cost-of-
service areas. These providers of interstate telecommunications services, as
well as some other entities, such as private carriers offering excess capacity
to end user customers, must contribute to a fund to pay for these programs. The
schools and libraries and rural health care support mechanisms are assessed
against interstate and international end-user revenues. The contribution level
and overall size of federal support may change. Several petitions for
administrative reconsideration of various FCC universal service orders are
pending, and there are a number of other proceedings relating to universal
service at the FCC and federal courts of appeals that are still ongoing. The
rules of the FCC also require that telecommunications carriers contribute to
the Number Portability Fund, the Telecommunications Relay Services Fund and the
North American Numbering Plan Administrator Fund.

   Communications Assistance for Law Enforcement Act. Telecommunications
carriers may incur significant expenses to assure that their networks comply
with the requirements of the Communications Assistance for Law Enforcement Act.
Under this statute, telecommunications carriers are required to:

  . provide law enforcement officials with call content and call identifying
    information pursuant to a valid electronic surveillance warrant; and

  . provide sufficient capacity for use by law enforcement officials in
    executing authorized electronic surveillance.

   While the telecommunications industry is attempting to negotiate legislative
and administrative provisions that would compensate carriers for some of the
costs associated with complying with this statute, as it stands today those
issues have not been definitively resolved.

 Local Exchange Carriers

   Telecommunications carriers that are classified as local exchange carriers
are subject to special regulatory provisions, in addition to those described
above. A local exchange carrier is defined as a provider of telephone exchange
service or exchange access. Telephone exchange service is defined as service
within a telephone exchange or connected system of exchanges operated to
provide inter-communicating service of the character ordinarily furnished by a
single exchange, covered by the local exchange charge, or comparable service
provided through a system of switches, transmission equipment or other
facilities, or combination thereof, by which a subscriber can originate and
terminate a telecommunications service. The universe of carriers that are
classified as local exchange carriers has never been fully defined by the FCC.
If an entity is found to be a local exchange carrier, it will have the
following obligations:

   Reciprocal Compensation. This requires all local exchange carriers to
establish compensation arrangements with other carriers for the transport and
termination of telecommunications.

   Resale. This requires all local exchange carriers to permit resale of their
telecommunications services without unreasonable restrictions or conditions.

   Number Portability. This requires all local exchange carriers to permit
users of telecommunications services to retain existing telephone numbers
without impairment of quality, reliability or convenience when switching to
another service provider at the same location.

                                       60
<PAGE>

   Non-discriminatory Access and Dialing Parity. This requires all local
exchange carriers to provide nondiscriminatory access to telephone numbers,
operator services, directory assistance and directory listing with no
unreasonable dialing delays and to give customers access to their selected
carrier without having to dial extra digits.

   Access to Rights-of-Way. This requires all local exchange carriers to permit
competing carriers access to poles, ducts, conduits and rights of way at
reasonable and nondiscriminatory rates, terms and conditions.

   In addition, incumbent local exchange carriers also face additional pricing,
network unbundling, and other obligations.

 State Telecommunications Regulation

   States also regulate telecommunications services, including through
certification of providers of intrastate services, regulation of intrastate
rates and service offerings, and other regulations. The Telecommunications Act
prohibits state and local governments from enforcing any law, rule or legal
requirement that prohibits or has the effect of prohibiting any person from
providing any interstate or intrastate telecommunications service. In addition,
under current policies of the FCC, any dedicated transmission service or
facility that is used more than 10% of the time for the purpose of interstate
or foreign communication is subject to the jurisdiction of the FCC to the
exclusion of any state regulation. Under the Telecommunications Act, states
retain jurisdiction to adopt regulations necessary to preserve universal
service, protect public safety and welfare, ensure the continued quality of
communications services and safeguard the rights of consumers. Accordingly, the
degree of state involvement in local telecommunications services may be
substantial. Furthermore, states generally give municipal authorities
responsibility over the access to rights-of-way, franchises, zoning, and other
matters of local concern, which means that localities may also have involvement
in the regulation of the telecommunications industry.

 Other Potential Regulation

   The laws and regulations relating to the liability of Internet access
providers for information carried on or disseminated through their networks are
currently unsettled both in the United States and abroad. In the United States,
the Children's Online Protection Act of 1998 imposes criminal penalties and
civil liability on anyone engaged in the business of selling or transferring
material that is harmful to minors by means of the Internet without restricting
access to this type of material by underage persons. In addition, similar
legislation has been passed or is being considered in many states and foreign
jurisdictions. Several private lawsuits seeking to impose this type of
liability on online service companies and Internet access providers are
pending. The imposition of potential liability on us and other Internet access
providers for information carried on or disseminated through our systems could
require us to implement measures to reduce our exposure to this liability,
which may require the expenditure of substantial resources or the
discontinuance of various service offerings. While we carry professional
liability insurance, it may not cover this type of liability and otherwise may
not be adequate to compensate us for any damages or costs incurred in defending
against these claims. The costs of defending against any claims and potential
adverse outcomes of these claims could have a material adverse effect on our
business.

   Due to the increase in Internet use and publicity, it is possible that other
laws and regulations that apply to commerce and communication over the Internet
will be adopted. The United States Congress has recently considered enacting
Internet laws regarding children's privacy, copyrights, the transmission of
sexually explicit material, the taxation of Internet services and transactions
and universal service contribution requirements for Internet accesss providers.
The European Union also recently enacted its own privacy regulations. The laws
governing the Internet, however, remain largely unsettled, even in areas where
there has been some legislative action. It may take years to determine whether
and how existing laws such as those governing intellectual property,
telecommunications, privacy, libel, taxation and other issues apply to the
Internet. In addition, the growth and development of the market for electronic
commerce may prompt calls for more stringent consumer protection laws, both in
the United States and abroad, which may impose additional burdens on companies
conducting business over the Internet.

                                       61
<PAGE>


   Other companies in our industry are not generally subject to direct
regulation by the FCC or any other governmental agency of the United States,
other than regulations that apply to all business organizations. However, in
connection with the merger between Bell Atlantic and GTE, the FCC has reviewed
our relationship with Verizon. In addition, the FCC continues to review its
regulatory position on the usage of the basic network and communications
facilities by Internet companies. To the extent that future regulatory licenses
or permissions are necessary or useful for us to provide IP-based services, we
will seek to obtain those licenses and permissions.

   Recently, the FCC adopted rules that direct incumbent local exchange
carriers to share their telephone lines with providers of high speed Internet
access and other data services. This ruling enables competitive carriers to
provide digital subscriber line-based services over the same telephone lines
simultaneously used by incumbent local exchange carriers to provide basic
telephone service. These changes may increase competitive pressures on
incumbent local exchange carriers in the offering of advanced
telecommunications services, including digital subscriber line services.

 International Regulatory Matters

   The laws relating to the provision of Internet and telecommunications
services in other countries vary substantially from country to country and are
undergoing a rapid process of development and change. There are a variety of
regulations in different jurisdictions regarding authorizations to provide
services and the manner in which services are to be provided. In addition, some
countries impose liability for providing access to prohibited content and
restrict the transfer of personal information. As we continue to expand into
international markets, these laws will have an increasing impact on our
operations. We do not know whether new or existing laws or regulations could
have a material adverse effect on us or our ability to offer some or all of our
services in any country.

   The ability for us to provide some or all of our Internet and other
services, including the ownership and operation of the necessary assets and
facilities in any particular country, will depend upon the extent to which
applicable laws and regulations permit us to provide our services. We believe
that the provision of some services, such as our voice-over-IP services, is
more likely to be subject to local country regulation than other Internet
services provided by us. Foreign countries treat voice-over IP differently.
Some countries impose no regulation on the service, while others allow voice-
over-IP but grant only a limited number of licenses to providers. In some
instances, the country requires licenses, but will grant an unlimited number of
licenses to providers. Finally, there are some countries that prohibit the
service altogether. Whether a carrier can provide voice-over-IP services in any
given country thus heavily depends on local regulations and the actions of
local governments.

   We currently have the ability to provide Internet services in many countries
without obtaining regulatory authorizations, approvals, or licenses. In eight
countries where we currently have or are in the process of commencing
operations, we have either obtained or have applied for regulatory approvals,
authorizations, or licenses for at least some of these services. These eight
countries include Brazil, Germany, Ireland, Italy, Japan, Mexico, The
Netherlands and Spain. In addition, as we enter new markets, we anticipate
obtaining similar approvals, authorizations and licenses as required by
applicable local rules and regulations in order to acquire, own and operate the
necessary assets and facilities, and to provide services, in these countries.
We do not know if we will obtain the necessary local regulatory approvals to
own and operate the assets and facilities necessary to provide service, or to
provide the services themselves, in any country, or that local country laws or
regulations will not change. Any failure to obtain approvals, or loss of
authorization, to provide services in any country could have a material adverse
effect on us.

Legal Proceedings

   We are not involved in any legal proceedings which we believe would, if
adversely determined, have a material adverse effect upon our business,
financial condition or results of operations.

fiscal year ended December 31, 1999 to our chief executive officer and each of
our four most highly compensated executives other than the chief executive
officer. GTE will not compensate our officers going forward and therefore this

these officers and is not indicative of the compensation that Genuity will pay
to these individuals in the future. The arrangements regarding the future
compensation and other incentives of our executive officers are currently under
study.

(1)  These amounts represent the annual bonus received by each executive under
     the GTE Corporation 1997 Executive Incentive Plan for the year ended
     December 31, 1999, of which a portion has been deferred into restricted
     stock units payable at maturity, generally a minimum of three years from
     the time of deferral, in common stock of GTE. GTE restricted stock units
     will not be granted to these officers in the future.

                                       67
<PAGE>


(2)  The number of restricted stock units received was calculated by dividing
     the sum of deferrals under (a) the annual bonus and (b) the LTIP payments
     by the average closing price of the common stock of GTE on the New York
     Stock Exchange Composite Transactions Tape for the 20 consecutive trading
     days following the release to the public of the financial results of GTE
     for the fiscal year in which the bonus and LTIP payments were earned.
     Each executive received matching restricted stock units on the basis of
     one additional restricted stock unit for every four restricted stock
     units earned. The dollar value of the
   matching restricted stock units is based on the average closing price of
   the common stock of GTE on the date of grant for each related restricted
   stock unit as described above. Additional restricted stock units were
   received on each dividend payment date based upon the amount of the
   dividend paid and the closing price of the common stock of GTE on the New
   York Stock Exchange Composite Transactions Tape on the dividend declaration
   date.

(3) The aggregate amount of the restricted stock units as of the end of the
    year ended December 31, 1999 was 12,416, 1,981, 1,000 and 4,406 for
    Messrs. Gudonis, Gibney, Parker and Monaghan. The aggregate value of these
    restricted stock units was $876,104, $139,784, $70,562 and $310,898 for
    Messrs. Gudonis, Gibney, Parker and Monaghan based solely upon the closing
    price of the common stock of GTE on December 31, 1999.
(4) These amounts represent payments under the GTE Corporation 1997 Long-Term
    Incentive Plan, of which a portion has been deferred into restricted stock
    units payable at maturity, generally a minimum of three years from the
    time of deferral, in common stock of GTE. These awards became immediately
    non-forfeitable and payable when the GTE stockholders and Bell Atlantic
    stockholders approved the merger. Each payment equaled the average of the
    performance percentage for each individual for the three award cycles
    completed prior to the date the merger was approved. We also included in
    these amounts projected dividends through the end of the award cycle. GTE
    restricted stock units will not be granted to these officers in the
    future.

(5) These amounts consist of contributions under the BBN Corporation
    Retirement Trust Agreement of $5,000 for Mr. Gudonis and under the GTE
    Savings Plan of $7,200 for Messrs. Gibney, Parker, Monaghan, and O'Brien.
    This column also includes contributions by GTE to the GTE Executive Salary
    Deferral Plan of $7,711, $5,172 and $6,333 for Messrs. Gibney, Monaghan
    and O'Brien. These executives will not be eligible to contribute to the
    GTE Savings Plan or the GTE Executive Salary Deferral Plan following the
    offering.

Option Grants in Last Fiscal Year

   The following table describes grants of stock options to purchase GTE
common stock to those executive officers listed in the Summary Compensation
Table for the year ended December 31, 1999. These options vest as to one-third
of the aggregate number of shares each year, commencing one year after the
date of grant. These stock option grants included a replacement stock option
feature. This feature provides that, if an executive exercises a stock option
by delivering previously owned shares that are sufficient to pay the exercise
price plus applicable tax withholdings, the executive will receive an
additional one-time stock option grant. The number of shares represented by
that option will be equal to the number of previously owned shares surrendered
in this transaction. This replacement stock option will be granted with an
exercise price equal to the fair market value on the date of grant. No stock
appreciation rights were granted for the year ended December 31, 1999. These
options were granted in recognition of past service to GTE. These officers
will not receive future grants of GTE or Verizon options following the
offering.

   The potential realizable value is calculated based on the term of the
option at its date of grant. It is calculated assuming that the fair market
value of the common stock of GTE on the date of grant appreciates at the
indicated annual rates compounded annually for the entire term of the option
and that the option is exercised and sold on the last day of its term for the
appreciated stock price. These numbers are calculated based on the
requirements of the Securities and Exchange Commission and do not reflect our
estimate of future stock price growth.

Awards Under Long Term Incentive Plans in Last Fiscal Year

   The following table sets forth grants under the GTE Corporation 1997 Long-
Term Incentive Plan to those executive officers listed in the Summary
Compensation Table for the year ended December 31, 1999. These executives will
receive no further awards under the GTE Corporation 1997 Long-Term Incentive
Plan as of the date of the offering. In addition, any payouts to these
executives will be reduced on a pro-rata basis as of the date of the offering.

   The estimated future payouts in the above table are calculated for
illustrative purposes only and are based upon the dividend rate and price of
the common stock of GTE at the close of business on December 31, 1999. The
target award is the dollar amount derived by multiplying the number of units
credited to the participant at the end of the award cycle by the average
closing price of the common stock of GTE as reported on the New York Stock
Exchange Composite Transactions Tape during the last 20 business days of the
award cycle.

   The maximum amount of the award has intentionally been left blank because it
is not possible to determine the maximum number of units until the award cycle
has been completed. The maximum amount of the award is determined by the extent
to which the actual results of GTE for five key financial measures exceed the
target levels.

Pension Plan

   The following table illustrates the estimated annual benefits payable under
the defined benefit pension plans of GTE. The information assumes normal
retirement at age 65 and is calculated on a single life annuity basis, based
upon final average earnings, integrated with social security as described
below, and years of service.

   Messrs. Gibney, Parker, Monaghan and O'Brien participate in the GTE Service
Corporation Plan for Employees' Pensions. The GTE Service Corporation Plan is a
noncontributory pension plan for the benefit of all employees of GTE Service, a
wholly owned subsidiary of GTE, and participating affiliates who are not
covered by collective bargaining agreements. It provides a benefit based on a
participant's years of service and earnings. Pension benefits provided by GTE
Service and contributions to the GTE Service Corporation Plan are related to
basic salary and incentive payments, exclusive of overtime, differentials, some
types of incentive compensation and other similar types of payments. Under the
GTE Service Corporation Plan, pensions are computed on a two-rate formula basis
of 1.15% and 1.45% for each year of service, with the 1.15% service credit
being applied to that portion of the average annual salary for the five highest
consecutive years that does not exceed $33,000, which is the portion of salary
subject to the Federal Social Security Act, and the 1.45% service credit being
applied to that portion of the average annual salary for the five highest
consecutive years that exceeds this level up to the statutory limit on
compensation.

   As of February 29, 2000, the credited years of service under the GTE Service
Corporation Plan were 11, 2, 31 and 1 for Messrs. Gibney, Parker, Monaghan and
O'Brien. Although these executives will no longer be employed by GTE Service
and will no longer accrue a pension under the GTE Service Pension Plan as of
the date of the offering, they along with other active employees of Genuity who
participate in the GTE Service Corporation Plan will continue to be credited
with additional years of age and service with Genuity for purposes of early
retirement eligibility under the GTE Service Corporation Plan. In addition,
they will have an assumed annual salary growth of 3.5% under the GTE Service
Corporation Plan. These special provisions will expire upon the earliest to
occur of the following:

  . the date that is five years after the date of offering;

  . an employee's termination of employment with Genuity; or

                                       70
<PAGE>


  .  the date that Genuity becomes a majority-owned subsidiary of Verizon.

   Service credit for GTE retiree welfare benefits will be provided in a
similar manner to the service recognition for pension purposes.

   Under federal law, an employee's benefits under a qualified pension plan,
such as the GTE Service Corporation Plan, are limited to set maximum amounts.
GTE maintains the Excess Pension Plan, which supplements the benefits of any
participant in the GTE Service Corporation Plan in an amount by which any
participant's benefits under the GTE Service Corporation Plan are limited by
law. In addition, the GTE Supplemental Executive Retirement Plan provides
additional retirement benefits under management incentive plans or special
arrangements as determined by GTE Service or one of its affiliates. The
Supplemental Executive Retirement Plan and the Excess Pension Plan benefits are
payable in a lump sum or an annuity.

Long-Term Stock Incentive Plan

   Our employees have historically been among those granted options to purchase
common stock of GTE. Our Long-Term Stock Incentive Plan has been adopted by our
board of directors and our sole stockholder. The Long-Term Stock Incentive Plan
provides for the following awards based on the Class A common stock: stock
options, stock appreciation rights, performance bonuses and other stock-based
awards. Awards may be granted to employees of Genuity or any entity in which it
owns at least a 10% interest. The Long-Term Stock Incentive Plan will be
administered by the executive compensation committee of our board of directors.
The administrator has the authority to determine eligibility, grant awards and
make all other determinations under the Long-Term Stock Incentive Plan. The
period or periods during which an award will be exercisable or remain
outstanding, including the manner of exercise and other details of awards will
be determined by the administrator consistent with the Long-Term Stock
Incentive Plan. Except in connection with promotions or significant increases
in responsibility or to ensure appropriate comparability with awards granted to
other participants, a person may receive only one award during the first four
years of the Long-Term Stock Incentive Plan. Our board of directors has the
power to amend or terminate the Long-Term Stock Incentive Plan. Unless
terminated earlier, the Long-Term Stock Incentive Plan will terminate on the
date of the annual meeting of stockholders in the year 2010.

   Stock options granted under the Long-Term Stock Incentive Plan may have a
term of up to 10 years and may be either incentive stock options, as defined in
the Internal Revenue Code, or nonqualified stock options. Stock options granted
under the Long-Term Stock Incentive Plan may not be assigned other than by will
or by applicable laws of descent and distribution. The option exercise price of
each stock option granted under the Long-Term Stock Incentive Plan in
connection with the offering will be the offering price and in the case of
other stock options will not be less than the fair market value of the Class A
common stock as of the date of grant. In general, stock options and other
awards may not be repriced after grant.

   The aggregate number of shares of Class A common stock available for awards
under the Long-Term Stock Incentive Plan will be 9% of the outstanding number
of shares of Class A common stock at the time of the offering. Of this amount,
5% will be available for awards to employees who were employed on or before
April 6, 2000; 1% will be available for awards to individuals who first became
or become employees after April 6, 2000 and on or before January 6, 2001; and
3% will be available for awards in connection with promotion and to individuals
who first become employed after January 6, 2001. Any shares attributable to the
expiration of the awards without exercise and similar events will be available
for awards to individuals regardless of their date of hire with the Company. In
no event will more than 50,000,000 shares be issued in satisfaction of
incentive stock options granted under the Long-Term Stock Incentive Plan. The
maximum number of shares for which stock options or stock appreciation rights
may be granted to any participant in any calendar year is 2,000,000. These
limits, as well as the exercise price of outstanding awards and other award
terms, are subject to appropriate adjustment to reflect stock splits, stock
dividends, and similar events.

Outside Directors' Compensation Plan

   We have an Outside Directors' Compensation Plan which, unless earlier
terminated, will terminate on the date of the annual meeting of stockholders in
the year 2010. Pursuant to the Outside Directors' Compensation Plan, non-
employee directors who have agreed to serve on our board of directors at the
time of this offering will receive, effective upon the completion of this
offering, a $30,000 annual cash fee and options to purchase 30,000 shares of
Class A common stock at an exercise price equal to the initial public offering
price. In addition, non-employee directors who agree after the initial public
offering to serve on the board of directors will receive, effective upon
election to the board of directors, a $30,000 annual cash fee and options to
purchase 30,000 shares of Class A common stock at an exercise price equal to
the fair market value at the time of the grant. Options issued to the directors
will vest in three equal installments. The first installment will immediately
vest on the date of grant, but will not become exercisable until the day
immediately before the first annual meeting of the stockholders. The second
installment will vest and become immediately exercisable on the day immediately
before the second annual meeting of the stockholders. The third installment
will vest and become immediately exercisable on the day immediately before the
third annual meeting of the stockholders. The number of shares subject to each
award, the exercise price and other terms of stock options under the Outside
Directors' Compensation Plan are subject to appropriate adjustment in the event
of a stock split, stock dividend or similar event. The vesting schedule
applicable to each stock option awarded under the Outside Directors'
Compensation Plan will be determined by the executive compensation committee of
our board of directors. If a director leaves our board of directors prior to
completing any three-year term as director, any then unvested stock option
would be forfeited. Any then vested and exercisable stock option would remain
exercisable for five years after the director leaves our board of directors
prior to the completion of a three-year term, subject to the maximum term of
the stock option and except as otherwise provided by the executive compensation
committee of our board of directors. Our board of directors has the power to
amend or terminate the Outside Directors' Compensation Plan.

Employment Agreements

   Genuity intends to enter into multi-year employment agreements with Messrs.
Gudonis, Farina, D. O'Brien, and Parker. The agreements will describe the
compensation opportunities and severance arrangements for each of these
individuals in addition to any post-employment restrictions.


Indemnification of Directors and Executive Officers and Limitation on Liability

   Our certificate of incorporation provides that our directors will not be
liable to us or our stockholders for monetary damages for any breach of
fiduciary duty, except to the extent otherwise required by the Delaware General
Corporation Law. This provision will not prevent our stockholders from
obtaining injunctive or other relief against our directors nor does it shield
our directors from liability under federal or state securities laws.

   Our certificate of incorporation also requires us to indemnify our directors
and officers to the fullest extent permitted by the Delaware General
Corporation Law, subject to a few very limited exceptions where indemnification
is not permitted by applicable law. Our certificate of incorporation also
requires us to advance expenses, as incurred, to our directors and executive
officers in connection with any legal proceeding to the fullest extent
permitted by the Delaware General Corporation Law. These rights are not
exclusive.

   Prior to the completion of this offering, we also intend to obtain
directors' and officers' insurance to provide coverage for our directors,
executive officers and some of our employees for specific liabilities,
including public securities matters. We believe that these indemnification
provisions and this insurance are necessary to attract and retain qualified
directors and officers.

   The limitation of liability and indemnification provisions in our
certificate of incorporation may discourage stockholders from bringing a
lawsuit against our directors for breach of their fiduciary duty. They may also
reduce the likelihood of derivative litigation against directors and officers,
even though an action, if successful, might benefit us and other stockholders.
Furthermore, the value of the Class A common stock may be adversely affected to
the extent we pay the costs of settlement and damage awards against directors
and officers as required by these indemnification provisions.

                           RELATED PARTY TRANSACTIONS

   We have provided below a summary description of the significant agreements
that we expect to execute with GTE Service Corporation and other affiliates of
GTE. These agreements will become effective at the completion of this offering.
These descriptions, which summarize the material terms of the agreements, are
not complete. You should read the full text of these agreements, which have
been filed with the Securities and Exchange Commission as exhibits to the
registration statement of which this prospectus is a part. We believe that the
terms of these agreements are comparable to those that would have resulted from
arms-length negotiations with parties other than GTE and its affiliates. We
intend to negotiate any future agreements with Verizon on the same basis.

Transition Services Agreements

   GTE and its affiliates currently provide a range of administrative and
support services to us. We will enter into an Agreement for Transition Services
and an Agreement for Information Technology Transition Services with GTE
Service.

   Agreement for Transition Services. Under this agreement, GTE Service will
provide, to the extent we continue to require them on a transitional basis, the
following services currently provided to us by various GTE affiliates:

  .  accounting and cash processing services, including payroll, asset
     accounting and accounts payable;

  .  billing and collection processing services;

  .  human resources services and benefits administration, including
     relationships with employee benefits providers; and

  .  real estate support services, including project management and
     environmental and safety services.

   Agreement for Information Technology Transition Services. We and GTE Service
will enter into this agreement in order to provide or receive, to the extent
either party continues to require them on a transitional basis, the following
services:

  .  software support services to ensure that software continues to run
     effectively after the offering; and

  .  hardware support services, including help desk support for personal
     computers, systems support centers for critical servers and local area
     network support.

   In addition, we will provide wide area network support to GTE Service, and
GTE Service will provide us with wide area network support in areas outside of
Bell Atlantic's local service region. GTE Service also will provide us with
computer programming and technical services, including the development of
software interfaces and modifications and enhancements to existing systems.

   Unless otherwise agreed, the ownership of any work product, including
intellectual property, created during the provision of services under either of
the transition service agreements will be determined under the terms and
conditions of the Software Development and Technical Services Agreement
described below. Similarly, any licenses relating to software will be granted
on the same terms and conditions as used in the Software License Agreement
described below.

   The fees for these transition services are fixed under the agreements and
were negotiated based on historical costs and comparable market prices. Both
agreements have a term of one year, although some services will be used for
less than a year. We will be able to terminate each or any portion of the
agreements at any time upon 120 days notice to GTE Service. As an exception,
the billing and collection processing services require 180 days notice in order
to provide adequate transition time. GTE Service has the right to terminate the

                                       73
<PAGE>

agreements on 120 days notice only with respect to the information technology
services that it receives from us. In connection with any termination or
expiration, GTE Service will be obligated to cooperate with us to transition
the work to another provider and to use commercially reasonable efforts to
secure our continued use of any necessary third party technology.

Purchase, Resale and Marketing Agreement

   We will enter into a Purchase, Resale and Marketing Agreement under which
Verizon will purchase services from us that will include Internet access,
value-added e-business services and private line and asychronous transfer mode
transport services. Verizon will be permitted to use these services internally
or resell them on a stand-alone basis or as part of a bundled solution. Those
services resold by Verizon may be co-branded with us or may be branded without
use of our marks. To the extent we jointly market our services with Verizon, we
will do so in compliance with all applicable federal law. We will not jointly
market our services with Verizon in states in which Verizon would not have
legal authority under applicable federal law to operate our company. We have
granted Verizon most favored customer pricing and volume-based discounts. Under
the terms of the agreement, Verizon will purchase at least $500 million of our
services over a five-year period. In the event that Verizon has not purchased
$200 million in services by the end of the third year of the contract, it would
be required to pay to us at that time the difference between the amount of
services purchased to date and $200 million. Similarly, in the event Verizon
has not purchased $500 million in services by the end of the fifth year of the
contract, it would be required to pay to us at that time the difference between
the amount of services purchased to that date, including any shortfall payment
made at the end of the third year, and $500 million. The minimum purchase
commitment is reduced in the event we do not comply with various obligations as
to competitive pricing and other aspects of service, sale and delivery.

   In order for us to properly plan for increasing demands for our services by
our customers, Verizon is required to provide us with 18-month forecasts of its
requirements on a quarterly basis. The agreement will remain in effect for five
years and is renewable for additional one-year periods by mutual consent of the
parties. Verizon may terminate the agreement on 90 days notice if a legislative
or regulatory order materially or adversely changes its rights, obligations or
risks in relation to the resale of our services. In this event, Verizon is
obligated to cooperate with us to ensure the orderly transition to us of all
outstanding reseller agreements, including the assignment of these agreements,
and to reimburse us for costs incurred by us relating to this transition.

   Under the agreement, if Verizon were to cause us to adjust our business as
described below in this paragraph in order to convert its Class B common stock,
it must provide us with 180 days prior written notice of the date on which it
intends to convert its Class B common stock. This notice will also indicate if
there are any states in which Verizon does not expect to have legal authority
under applicable federal law to operate a long distance business at the time of
the conversion of the Class B common stock. Upon receipt of this notice, we
will adjust our operations in the states designated by Verizon in a manner
necessary to allow Verizon to be in compliance with applicable federal law in
these states after Verizon obtains a greater than 10% equity interest in our
capital stock. In no event will the states designated by Verizon account for
more than 3% of our total revenues during the preceding 12 months and in no
event shall the adjustment of our operations result in the loss of overall
revenue in excess of 3% of our total revenues during the preceding 12 months.
Verizon will agree to pay an amount necessary to make us financially whole as a
result of our modification of our business pursuant to this arrangement.

   In conjunction with the Purchase, Resale and Marketing Agreement described
above, we also plan to provide to Verizon undersea cable capacity in the ARCOS-
1 Caribbean Ring System and have committed to negotiate with Verizon with
respect to operating capacity on the Americas III Cable Network currently under
construction.

Intellectual Property Agreements

   We intend to enter into the following agreements with GTE Service in order
to allocate rights relating to existing and future patents, software, other
types of intellectual property and technical services.

                                       74
<PAGE>

   Intellectual Property Ownership and Cross License Agreement. This agreement
will apportion the ownership of existing patents, patent applications and other
types of intellectual property between GTE Service and us. Under the agreement,
existing patents and patent applications that relate exclusively to us will be
owned exclusively by us. Existing patents and patent applications that relate
to both us and GTE Service will be jointly owned by us and GTE Service. The
remaining existing patents and patent applications that relate to GTE Service
will be owned exclusively by GTE Service. Both we and GTE Service will grant
each other a perpetual, non-exclusive, royalty-free worldwide license to each
other's existing patents and patent applications. In addition, we will jointly
own any currently existing, non-statutory intellectual property. Those patents
and patent applications that either GTE Service or we develop in the future
will be owned pursuant to applicable laws or any controlling agreements.

   Software License Agreement. We plan to enter into a Software License
Agreement with GTE Service under which it will grant us a non-exclusive, non-
transferable, worldwide license to use software programs owned by GTE Service
for our internal operations. In addition, GTE Service will provide us with
updates to the licensed software programs pursuant to the Agreement for
Information Technology Transition Services described above. In exchange for the
license, we will pay GTE Service an annual license fee for each licensed
software program. The term of each license will be one year and will be
automatically renewable for successive one-year periods upon the payment of
annual license fees. We may terminate or cancel any software license upon 30
days written notice to GTE Service. The licenses that GTE Service will grant us
pertain to the object code of the licensed software programs only. The source
code of the licensed software programs will be placed in an escrow account and
will be made available to us pursuant to the terms and conditions of a separate
escrow agreement.

   Software Development and Technical Services Agreement. Under this agreement,
GTE Service will provide us with software development and other technical
services. For services related exclusively to our business, the newly created
deliverable, including any newly created software and accompanying
documentation, and all intellectual property rights in the deliverable, will be
transferred to us by GTE Service. In return, we will grant to GTE Service a
perpetual, royalty-free worldwide license to any deliverable owned by us for
the internal use of GTE Service only. For services not related exclusively to
us, GTE Service will retain ownership of any deliverable and will grant us a
non-exclusive, royalty-free, non-sublicensable, non-transferable license to use
the deliverable owned by GTE Service for our internal use only. The agreement
will have a term of one year and will be renewable for successive one-year
terms by mutual consent of the parties. We may terminate the agreement at any
time following written notice to GTE Service.

Network Monitoring Agreement

   Under the terms of an existing agreement, we receive continuous monitoring
for some elements of our network infrastructure from GTE Network Services,
including monitoring of network-enabling devices and processes to detect
anomalies occurring in the network. The fees for monitoring services are fixed
under the agreement and were negotiated based on historical costs and
comparable market prices. The agreement may be terminated by us on 90 days
notice.

Real Estate Agreements

   We plan to enter into several agreements with Verizon to allocate space in
various leased and owned properties between us and Verizon. None of the
properties involved are material to our operations or business. Provisions of
each agreement, including the lease and sublease payment of rent terms, vary
depending on the underlying lease at the specified property and the result of
negotiations pertaining to specific issues at a specified property.

   In order to effect our transition to a stand-alone company, GTE also has
agreed to issue new guaranties and to continue existing guaranties in order to
support our real estate obligations. GTE has agreed to continue to issue new
guaranties until six months following this offering or the date on which both
Standard & Poor's and Moody's publish a credit rating for us, whichever occurs
first. We have agreed to pay GTE a commercially reasonable fee during the time
the guaranties are in force.

                                       75

Registration Rights Agreement

   Immediately after the completion of this offering, under a Registration
Rights Agreement dated     , 2000, Verizon and its transferees or assignees
will be entitled to cause us to register shares of Class A common stock that
are issued following the conversion of either our Class B common stock or our
Class C common stock. We may postpone the filing of any registration statement
up to two times for a total of 90 days in the event that the filing (1) would
require the disclosure of sensitive information that would be seriously
detrimental to us or (2) would occur at a time in which we are working on our
annual audited financial statements. If marketing reasons dictate, the
managing underwriter of any underwritten offering will have the right to limit
the number of shares of common stock that Verizon and its transferees or
assignees include in any registration statement. We will pay all expenses
incurred in connection with the filings described below, except for
underwriters' and brokers' discounts and commissions, which will be paid by
each of the selling stockholders.

   Demand Registration Rights. At any time after six months following this
offering, Verizon and its transferees or assignees can request on sixteen
occasions that we register all or a portion of their shares of Class A common
stock on a registration statement so long as the total number of shares
requested to be registered is at least the greater of (1) the value of five
percent of the shares of Class A common stock issued and outstanding on the
date of this offering and (2) an aggregate value of $100,000,000. We are not
required to file more than one demand registration statement within 90 days of
the effectiveness of any registration statement, other than a shelf
registration statement as described below.

   Piggyback Registration Rights. At any time after six months following this
offering, if we register any of our securities for public sale, either for our
own account or for the account of any holder of our securities, Verizon and
its transferees or assignees will have the right to include their shares of
common stock in such registration. This right, however, applies only to a
registration statement relating to an underwritten public offering for cash.

   Shelf Registration Rights. At any time after six months following this
offering, in the event that Verizon or one of its affiliates issues any
securities that are convertible into or exchangeable for shares of Class A
common stock owned by Verizon, Verizon will have the right to request that we
file a registration statement relating to the conversion or exchange of the
securities issued by Verizon or its affiliates. However, we will not be
required to make such a filing unless the total number of shares requested to
be registered is at least the greater of (1) the value of five percent of the
shares of Class A common stock issued and outstanding on the date of this
offering and (2) an aggregate value of $100,000,000, in each case based on the
closing trading price of the Class A common stock on the date the demand to
file the shares is made.

Recapitalization Agreement

   GTE will execute a recapitalization agreement in connection with its
receipt of the Class B common stock. Under this agreement, GTE will exchange
all of the shares of our common stock for such number of shares of Class B
common stock that will equal 9.5% of the total number of shares of our common
stock outstanding immediately after the completion of this offering. The
recapitalization agreement contains customary representations and warranties,
including with respect to the issuance of the Class B common stock. The
recapitalization agreement also includes provisions enabling Verizon to
purchase additional shares of Class B common stock under the circumstances
described in the section in "Description of Capital Stock" entitled "Right to
Purchase Additional Shares Upon Conversion." In addition, the recapitalization
agreement contains provisions requiring us to obtain the consent of Verizon
prior to taking the following actions:

  . making any acquisition or series of related acquisitions with a purchase
    price that exceeds 20% of our market capitalization at the time of such
    acquisition. Market capitalization is determined by multiplying the
    closing price of our Class A common stock on the date of determination by
    the number of shares of common stock outstanding on that date, assuming
    for purposes of this calculation that the Class B common stock has been
    converted to the maximum extent permitted under our certificate of
    incorporation;

                                      76

  . making any acquisition with a purchase price in excess of $100 million or
    entering into any joint venture which has a fair market value in excess
    of $100 million immediately after formation, in each case that is not
    closely related to our business;

  . making any disposition or series of related dispositions for
    consideration, including the assumption of indebtedness in excess of 20%
    of our market capitalization at the time of such disposition or, if
    earlier, of our entering into such disposition agreement;

  . incurring indebtedness (including capital leases, guarantees of
    indebtedness of others, letters of credit and indebtedness acquired in
    connection with any acquisition, but excluding trade accounts payable)
    (1) in any calendar year that exceeds $3.85 billion, net of any
    indebtedness repaid during that same calendar year, or (2) at any time,
    if immediately after the incurrence thereof, our indebtedness would
    exceed $11.0 billion;

  . entering into any agreement or arrangement that (1) binds or purports to
    bind, or following conversion, would bind or purport to bind, Verizon or
    any of its affiliates, or (2) contains provisions that trigger a default
    or require a material payment when Verizon exercises its rights to
    convert the Class B common stock;

  . declaring extraordinary dividends or making other extraordinary
    distributions to the holders of our capital stock;

  . issuing any equity securities or securities convertible or exercisable
    into equity securities except for:

    (1) equity securities issued in connection with acquisitions, in an
        aggregate amount not to exceed 30% of the shares of common stock
        outstanding upon the completion of this offering, including shares
        of common stock outstanding immediately after the exercise of the
        underwriters' over-allotment option, if any;

    (2) equity securities issued to fund operating needs, including capital
        expenditures, in an aggregate amount not to exceed 5% of the shares
        of common stock outstanding upon the completion of this offering,
        including shares of common stock outstanding immediately after the
        exercise of the underwriters' over-allotment option, if any;

    (3) equity securities issued or granted to our employees, provided
        that:

      (a) the number of equity securities issued or granted to individuals
          who were employees on April 6, 2000 does not exceed in the
          aggregate 5% of the shares of common stock outstanding upon the
          completion of this offering, including shares of common stock
          outstanding immediately after the exercise of the underwriters'
          over-allotment option, if any;

      (b) the number of equity securities issued or granted to individuals
          who first become our employees within nine months of April 6,
          2000, other than individuals who become our employees as a result
          of their former employer being acquired by us, does not exceed in
          the aggregate 1.0% of the shares of common stock outstanding upon
          the completion of this offering, including shares of common stock
          outstanding immediately after the exercise of the underwriters'
          over-allotment option, if any;

      (c) the number of equity securities issued or granted to individuals
          who become our employees beginning on or after January 6, 2001,
          other than individuals who become our employees as a result of
          their former employer being acquired by us, does not exceed in
          the aggregate 3.0% of the shares of common stock outstanding upon
          the completion of this offering, including shares of common stock
          outstanding immediately after the exercise of the underwriters'
          over-allotment option, if any;

      (d) the number of equity securities issued to a trustee or other
        fiduciary, or granted or reserved for issuance to our employees
        described in the previous clauses (a), (b) and (c) in connection
        with

                                       77
<PAGE>


        our 401(k) or any similar plan does not exceed 0.5% of the shares
        outstanding upon completion of this offering, including shares of
        common stock outstanding immediately after the exercise of the
        underwriters over-allotment option, if any; and

      (e) the number of shares issued or granted to individuals who become
          our employees as a result of their former employer being acquired
          by us, including equity securities issued, granted or reserved
          for issuance to a trustee or other fiduciary or to our employees
          described in clause (d) in connection with our 401(k) or any
          similar plan, does not exceed 6.0% multiplied by the total of (i)
          the number of shares of common stock outstanding upon the
          completion of this offering plus (ii) the number of shares issued
          in connection with acquisitions completed by us minus (iii) the
          aggregate number of shares of common stock that may be issued
          under clauses (a), (b), (c) and (d) above.




   For the purpose of calculating the percentage of the shares of common stock
outstanding upon the completion of this offering, all shares of Class B common
stock shall be deemed to have been converted into shares of Class A common
stock to the maximum extent permitted under our certificate of incorporation.
If options expire or terminate after being granted under subsection (3) above,
those shares become available for any of the purposes stated in subsections (1)
through (3).

   We will not be required to obtain the consent of Verizon to take the above
actions if at any time:

  . Verizon and its affiliates do not have the right to vote more than 50% of
    the then outstanding shares of Class B common stock; or

  . Verizon and its affiliates do not own shares of common stock constituting
    more than 10% of our then outstanding common stock; or

  . Any third party and its affiliates own more than 50% of the then
    outstanding shares of Class B common stock.

   Verizon may assign these consent rights to a third party who may exercise
them so long as the third party directly or indirectly:

  . owns and has the right to vote more than 50% of the then outstanding
    shares of Class B common stock; and

  . owns or has the right to acquire more than 50% of our then outstanding
    common stock.

   For purposes of calculating the ownership of our common stock in the two
preceding paragraphs, shares of Class B common stock that can never be
converted into more than their proportionate share of 10% of our total common
stock outstanding shall be considered to have been converted on that basis. All
other shares of Class B common stock shall be considered to have been converted
to the maximum extent permitted under our certificate of incorporation.

                                SOLE STOCKHOLDER

   Prior to this offering, all of the outstanding shares of our common stock
will be owned by GTE. The mailing address of GTE Corporation is 1255 Corporate
Drive, Irving, Texas 75038. Upon completion of this offering, Verizon will
beneficially hold all of the outstanding shares of our Class B common stock,
which will represent 9.5% of the voting power of our outstanding capital stock
at that time, before giving effect to any outstanding options to purchase
shares of our Class A common stock under our long-term incentive plans. Except
for Verizon, we are not aware of any person or group that will beneficially own
more than five percent of our Class A common stock or Class B common stock upon
completion of this offering. There will not be any shares of our Class C common
stock outstanding immediately after this offering.

   None of our directors and executive officers beneficially owns any shares of
our common stock. We intend to grant to our officers and directors options to
purchase an aggregate of 6,075,000 shares of our Class A common stock with an
exercise price equal to the public offering price set forth on the cover page
of this prospectus. Assuming the exercise of these options, these officers and
directors would beneficially own 3% of our Class A common stock.

                          DESCRIPTION OF CAPITAL STOCK

   Immediately following the completion of this offering, our authorized
capital stock will consist of 1,600,000,000 shares of Class A common stock, par
value $0.01 per share, 21,000,000 shares of Class B common stock, par value
$0.01 per share, 800,000,000 shares of Class C common stock, par value $0.01
per share, and 50,000,000 shares of preferred stock, par value $0.01 per share.
Immediately following the completion of this offering, there will be
outstanding:

  .  173,913,000 shares of Class A common stock, all of which will be owned
     by the investors purchasing shares in this offering;

  .  options to purchase approximately 50,000,000 shares of Class A common
     stock;

  .  18,256,000 shares of Class B common stock, all of which will be owned by
     Verizon;

  .  no shares of Class C common stock; and

  .  no shares of preferred stock.

   In the event that the underwriters exercise any portion of the over-
allotment option, we will subdivide our shares of Class B common stock so that
Verizon will beneficially own 9.5% of the total number of shares of common
stock then outstanding, before giving effect to any issuance of shares of Class
A common stock upon the exercise of outstanding options of Genuity.

Common Stock

   The shares of our Class A common stock, Class B common stock and Class C
common stock are identical in all respects except for voting rights, conversion
rights and as otherwise described below. The rights, preferences and privileges
of holders of our Class A common stock, Class B common stock and Class C common
stock are subject to the rights of the holders of shares of any other class of
common stock that we may authorize and issue and any series of preferred stock
that we may designate and issue in the future.

   Voting Rights. Each share of Class A common stock and Class B common stock
entitles the holder to one vote on each matter submitted to a vote of our
stockholders. Each share of Class C common stock entitles the holder to five
votes on each matter. Except as required by applicable law or as discussed
below, the holders of the Class A common stock, Class B common stock and Class
C common stock vote together as a single class on all matters submitted to a
vote of our stockholders.

   So long as 50% of the shares of Class B common stock outstanding immediately
following the completion of this offering, including additional shares of Class
B common stock issued to Verizon in connection with the exercise of the over-
allotment option, remain outstanding, no person or group of persons acting
together, as determined pursuant to Rule 13d-3 under the Securities Exchange
Act of 1934, will be permitted to vote any of the shares of Class A common
stock beneficially owned by that person or group of persons in excess of 20% of
the aggregate number of then outstanding shares of Class A common stock, except
as set forth below. To the extent any person or group of persons beneficially
owns more than 20% of the shares of Class A common stock, the vote of any
excess shares will be apportioned among the other holders of Class A common
stock in accordance with their respective percentage ownership. In order to
enforce this limitation, our certificate of incorporation permits us to require
stockholders or groups that have filed or, in the reasonable judgment of our
board of directors after consultation with legal counsel, were required by law
to have filed, a Schedule 13D or Schedule 13G, or any successor schedules or
forms, under the Securities Exchange Act, to certify to us in writing the
number of shares of Class A common stock beneficially owned by them as of the
applicable record date. This prohibition on voting excess shares of Class A
common stock does not apply to Verizon or its affiliates or to any person or
group of persons that acquired Class A common stock by converting Class B
common stock.

   So long as any shares of Class B common stock remain outstanding, the
holders of Class B common stock, voting separately as a class, will have the
right to elect one member of our board of directors.

                                       80
<PAGE>

The holders of Class B common stock are also entitled to vote with the holders
of the Class A common stock and Class C common stock in the election of the
other directors. You should refer to the section in "Management" entitled
"Composition of Board of Directors" for a more detailed description of our
board of directors.

   In addition, the affirmative vote of the holders of a majority of the
outstanding shares of Class B common stock, voting separately as a class, is
required before we:

  .  amend our certificate of incorporation, or amend our bylaws in a way
     that affects the rights of the holders of the Class B common stock;

  .  agree to enter into a merger, consolidation or sale, lease or other
     disposition of all or substantially all of our assets;

  .  file or declare bankruptcy or liquidation;

  .  authorize additional shares of our capital stock;

  .  materially change the nature or scope of our business from the
     description of the business and business plan in this prospectus; or

  .  take any action that would make it unlawful for a holder of Class B
     common stock to exercise its conversion rights.

   Except as described in the next paragraph, this class vote will not be
required if at any time:

  .  Verizon and its affiliates do not have the right to vote more than 50%
     of the then outstanding shares of Class B common stock;

  .  Verizon and its affiliates do not own shares of common stock
     constituting more than 10% of our then outstanding common stock; or

  .  Any third party and its affiliates own more than 50% of the then
     outstanding shares of Class B common stock.

   The class vote of the holders of Class B common stock will still be required
if:

  .  Verizon has transferred shares of Class B common stock to a third party
     that directly or indirectly owns and has the right to vote more than 50%
     of the then outstanding shares of Class B common stock; and

  .  the Class B common stock at the time constitutes more than 50% of our
     then outstanding common stock.

   For purposes of calculating the ownership of our common stock in the two
preceding paragraphs, shares of Class B common stock that can never be
converted into more than their proportionate share of 10% of our total common
stock outstanding shall be considered to have been converted on that basis. All
other shares of Class B common stock shall be considered to have been converted
to the maximum extent permitted under our certificate of incorporation.


   We have also entered into an agreement that requires us to obtain the
consent of Verizon or its assignees prior to taking other actions. You should
refer to the section in "Related Party Transactions" entitled "Recapitalization
Agreement."

   Dividends, Distributions and Stock Splits. Subject to preferences that may
apply to any outstanding series of preferred stock, the holders of each of our
three classes of common stock are entitled to receive dividends at the same
rate if, as and when dividends are declared by the board of directors out of
assets legally available therefor. In the case of dividends or distributions
payable in common stock, only shares of Class A common stock will be
distributed on Class A common stock, only shares of Class B common stock will
be distributed on Class B common stock and only shares of Class C common stock
will be distributed on Class C common stock. Except as described above, in no
event may any of the shares of Class A common stock, Class B common stock or
Class C common stock be subdivided or combined in any manner unless each other
class is subdivided or combined in the same proportion.

                                       81

   Conversion of Class A Common Stock. The Class A common stock has no conver-
sion rights.

   Conversion of Class B Common Stock. Immediately after the completion of this
offering, Verizon will own all of our outstanding shares of Class B common
stock. Although the ability of Verizon to convert its Class B common stock is
limited by the proposal to the FCC, these shares by their terms are convertible
at any time into either:

  .  shares of Class A common stock equal to 10% of our total common stock
     immediately after the conversion; or

  .  800 million shares of Class A common stock or, for Verizon or any of its
     affiliates and at their election, Class C common stock, which represents
     approximately 82%, or 80% if the underwriters exercise in full the over-
     allotment option, of our shares of common stock outstanding immediately
     following this offering.

   Under the proposal to the FCC:

  .  if Verizon has not eliminated Section 271 restrictions applicable to its
     operation of our business as to at least 50% of Bell Atlantic in-region
     lines, the outstanding shares of our Class B common stock can only be
     converted into shares of our Class A common stock that after the
     conversion will represent 10% of our total common stock then
     outstanding. If Verizon transfers the Class B common stock before
     meeting this 50% threshold, the transferee's conversion rights would be
     similarly limited;

  .  if Verizon has eliminated applicable Section 271 restrictions as to at
     least 50% of Bell Atlantic in-region lines, it could transfer its shares
     of Class B common stock to one or more third parties who would then be
     able to convert them in the aggregate into 800 million shares of Class A
     common stock;

  .  if Verizon has eliminated applicable Section 271 restrictions as to 100%
     of Bell Atlantic in-region lines, Verizon or its affiliates could
     convert the Class B common stock into 800 million shares of Class A
     common stock or Class C common stock; and

  .  if Verizon has eliminated applicable Section 271 restrictions as to 95%
     of Bell Atlantic in-region lines, Verizon may require us to reconfigure
     our operations in one or more Bell Atlantic in-region states where
     Verizon has not eliminated those restrictions in order to bring those
     operations into compliance with Section 271 and therefore be able to
     convert the Class B common stock into 800 million shares of Class A
     common stock or Class C common stock. To require us to reconfigure our
     operations, Verizon must give the FCC at least 90 days advance notice of
     its intent to exercise its conversion rights and submit to the FCC a
     plan for the reconfiguration of our operations in the relevant state or
     states. The reconfiguration of our operations must not result in the
     loss to us of more than 3% of our annual revenue and Verizon must
     reimburse us for the cost of such reconfiguration.

   If Verizon were to cause us to reconfigure our business in the manner
described in the preceding paragraph, it must also comply with the provisions
of the Purchase, Resale and Marketing Agreement, including providing us with
180 days prior written notice of the date on which it intends to convert its
Class B common stock and paying us an amount necessary to make us financially
whole as a result of these modifications to our business. You should refer to
the section in "Related Party Transactions" entitled "Purchase, Resale and
Marketing Agreement" for more information.

   Notwithstanding the above provisions, if before Verizon has eliminated
applicable Section 271 restrictions as to at least 50% of Bell Atlantic in-
region lines, a court or governmental agency of competent jurisdiction rules
that Verizon's interest in us violates Section 271 of the Telecommunications
Act, then under the proposal to the FCC:

  .  Verizon can at that time convert its shares of our Class B common stock
     into 800 million shares of our Class A common stock or Class C common
     stock for the purpose of disposing of all such shares above 10%; or

  .  Verizon can sell some or all of its Class B common stock to a third
     party who shall have the right to convert such shares into 800 million
     shares of our Class A common stock or Class C common stock.

                                       82
<PAGE>


   Under the proposal to the FCC, if Verizon has not eliminated the applicable
Section 271 restrictions as to 100% of Bell Atlantic in-region lines on or
before     , 2005, which date may be extended under conditions that we describe
below, Verizon's ability to convert the Class B common stock into 800 million
shares of Class A common stock or Class C common stock will expire. Verizon
will continue to retain its right to convert its shares into shares of Class A
common stock representing 10% of our total common stock then outstanding. If
Verizon has satisfied the applicable Section 271 restrictions as to 100% of
Bell Atlantic in-region lines on or before that date, its ability to convert
the Class B common stock does not expire. Class B common stock transferred by
Verizon to a third party will not be subject to this expiration limitation.


   Under the proposal to the FCC, Verizon may file a petition to extend the
date by which Verizon must eliminate the applicable Section 271 restrictions,
and in the event of that filing, the date will be extended to      , 2006 or
later at the discretion of the FCC, if by    , 2005 Verizon has eliminated the
applicable Section 271 restrictions on:

  (1)  all but 10% of Bell Atlantic in-region lines; or

  (2)  all of Bell Atlantic in-region lines except for:

    .  lines in any one state, regardless of the number of Bell Atlantic in-
       region lines accounted for by that state; and

    .  lines in additional states accounting for, in the aggregate, up to 5%
       of Bell Atlantic in-region lines.

   If on the original or extended date referred to above Verizon has entered
into an agreement to sell the Class B common stock to a third party, then
Verizon shall be given a reasonable period of time to allow for the completion
of the sale under an agreement and the purchaser's immediate conversion of the
Class B common stock thereafter.

   Conversion of Class C Common Stock. The Class C common stock is convertible
into Class A common stock, in whole or in part, at any time and from time to
time at the option of the holder, on the basis of one share of Class A common
stock for each share of Class C common stock. Each share of Class C common
stock will automatically convert into one share of Class A common stock if at
any time the aggregate number of outstanding shares of Class C common stock,
together with any shares of Class C common stock issuable upon conversion of
Class B common stock, constitute less than 10% of our then outstanding
common stock.

   Transfer of Class C Common Stock. If any party other than Verizon or its
affiliates converts shares of our Class B common stock, such party can only
receive shares of our Class A common stock. Verizon can receive shares of our
Class C common stock upon conversion of its Class B common stock, either after
eliminating applicable Section 271 restrictions as to 100% of Bell Atlantic in-
region lines or, in connection with a disposition of Verizon's shares of our
common stock, after eliminating applicable Section 271 restrictions as to at
least 50% of Bell Atlantic in-region lines. In either event, Verizon can
transfer shares of our Class C common stock to one or more persons, provided
that any shares of our Class C common stock so transferred will automatically
convert into shares of our Class A common stock on the earlier to occur of
(1) any subsequent transfer of ownership of such shares or (2) the first
anniversary of the transfer of such shares by Verizon. As a result of the
foregoing, one or more third parties could own shares of our Class C common
stock.

   Limitation on Receipt of Sale Proceeds. Under the proposal to the FCC, if
Verizon sells its shares of our Class B common stock, or the shares of our
common stock received by it on conversion of its shares of our Class B common
stock, after eliminating Section 271 restrictions applicable to its operation
of our business as to at least 50% but less than 95% of Bell Atlantic in-region
lines, Verizon will be required to pay to the U.S. Treasury the portion of its
after tax proceeds that exceeds the proceeds it would have received for the
shares it is not permitted to hold from a comparable investment in the Standard
& Poors 500 Index. This payment may be reduced in the discretion of the FCC.

   Right to Purchase Additional Shares Upon Conversion. If at any time during
the one year following the conversion by Verizon or its affiliates of any
shares of Class B common stock Verizon and its affiliates control shares of
Class A common stock and Class C common stock that together equal or exceed 70%
of the total number of shares of common stock then outstanding, Verizon will
have the right to acquire from us a number of shares of Class A common stock so
that, immediately after the acquisition, Verizon and its affiliates' combined
ownership of Class A and Class C common stock will be equal to 80% of the total
number of shares of common stock then outstanding. This right to purchase
additional shares may be exercised only one time. The price payable per share
in this purchase would consist of cash or other property with a fair market
value equal to the average of the closing prices for the Class A common stock
for the 30 trading days immediately preceding the date of the purchase. In the
event Verizon elects to pay the purchase price in property, the fair market
value of such property will be established by an appraisal conducted by a
nationally recognized appraiser chosen by our independent directors. Verizon
shall not be permitted to pay the purchase price in property if our independent
directors determine that:

  .  our ownership of such property will violate the law including without
     limitation any federal or state regulations applicable to us; or

  .  the property is not reasonably useful to us in light of our then
     existing business plan.

   Liquidation. In the event of any dissolution, liquidation, or winding up of
our affairs, whether voluntary or involuntary, the holders of the Class A
common stock, the Class B common stock and the Class C common stock will be
entitled to share ratably, in proportion to the number of shares they represent
of our outstanding common stock, in the assets legally available for
distribution to stockholders, in each case after payment of all of our
liabilities and subject to preferences that may apply to any series of
preferred stock then outstanding. We may not dissolve, liquidate or wind up our
affairs without obtaining the consent of the holders of the outstanding shares
of our Class B common stock.

   Mergers and Other Business Combinations. If we enter into a merger,
consolidation or other similar transaction in which shares of our common stock
are exchanged for or converted into securities, cash or any other property, the
holders of each class of our common stock will be entitled to receive an equal
per share amount of the securities, cash, or other property, as the case may
be, for which or into which each share of any other class of common stock is
exchanged or converted; provided that in any such merger, consolidation or
other similar transaction, the holders of the shares of Class B common stock
shall be entitled to receive, at their election, either (1) the merger
consideration such holders would have received had they converted their shares
of Class B common stock immediately prior to the consummation of such
transaction or (2) a new security that is convertible into the merger
consideration and has substantially identical voting and other rights as the
Class B common stock. In any transaction in which shares of capital stock are
distributed, the shares that are exchanged for or converted into the capital
stock may differ as to voting rights and conversion rights only to the extent
that the voting rights and conversion rights of Class A common stock, Class B
common stock and Class C common stock differ at that time. As described above,
the holders of the Class B common stock, voting separately as a class, must
consent to any merger, consolidation or other similar transaction.

   Other Provisions. The holders of our Class A common stock, Class B common
stock and Class C common stock are not entitled to preemptive rights. There are
no redemption provisions or sinking fund provisions that apply to the Class A
common stock, the Class B common stock or the Class C common stock.

Preferred Stock

   Our board of directors has the authority, without further action by the
holders of our Class A common stock or Class C common stock, to issue from time
to time, shares of our preferred stock in one or more series. The issuance of
shares of preferred stock is, however, subject to the approval of holders of
the Class B common stock. Once the approval of the holders of the Class B
common stock has been obtained, our board of directors may fix the number of
shares, designations, preferences, powers and other special rights of the
preferred stock. The preferences, powers, rights and restrictions of different
series of preferred stock may differ.

                                       84
<PAGE>

The issuance of preferred stock could decrease the amount of earnings and
assets available for distribution to holders of common stock or affect
adversely the rights and powers, including voting rights, of the holders of
common stock. The issuance of preferred stock, while providing flexibility in
connection with possible acquisitions and other corporate purposes, may also
have the effect of discouraging, delaying or preventing a change in control of
our company, regardless of whether the transaction may be beneficial to
stockholders. After the closing of this offering, there will be no shares of
preferred stock outstanding and we have no current plans to issue any shares of
preferred stock.

Anti-takeover Effects of Delaware Law and our Certificate of Incorporation and
Bylaws

   In addition to the special approval and conversion rights of the Class B
common stock and the provision referred to above relating to the voting of
beneficial ownership above 20% of our outstanding shares of Class A common
stock, there are provisions of the Delaware General Corporation Law and other
provisions of our certificate of incorporation and bylaws that may be deemed to
have an anti-takeover effect and may discourage, delay or prevent a tender
offer or takeover attempt that a stockholder might consider in its best
interest, including those attempts that might result in a premium over the
market price for the shares held by our stockholders. Under our bylaws, the
provisions summarized below regarding our classified board, action by written
consent and stockholder meetings can be amended by the vote of either:

  .  both 80% of the voting power of all of our voting stock and 50% of the
     voting power of our Class B common stock; or

  .  80% of the voting power of the Class B common stock, provided that such
     vote occurs in connection with the delivery of a conversion notice
     pursuant to which the Class B common stock is converted into greater
     than 10% of our common stock.

   Classified Board of Directors. Other than the director elected by the
holders of our Class B common stock, our board of directors will be divided at
our initial meeting of stockholders into three classes of directors, as nearly
equal in size as possible, serving staggered three-year terms. Upon expiration
of the term of a class of directors, the directors in that class will be
elected for three-year terms at the annual meeting of stockholders in the year
in which the term for that class of directors expires. In addition, our bylaws
provide that directors, other than the director elected by the holders of the
Class B common stock, may be removed only for cause by the affirmative vote of
the holders of a majority of the shares of capital stock entitled to vote in
the election of directors. Under our bylaws, a vacancy on the board of
directors, other than a vacancy with respect to the director elected by the
holders of the Class B common stock but including a vacancy resulting from an
enlargement of the board of directors, may only be filled by vote of a majority
of the directors then in office. The classification of the board of directors
and the limitations on removing directors and filling vacancies could have the
effect of making it more difficult for a third party to acquire, or of
discouraging a third party from acquiring, control of us.

   Stockholder Action; Special Meeting of Stockholders. Our certificate of
incorporation eliminates the ability of our Class A common stock to act by
written consent. Our bylaws further provide that special meetings of our
stockholders may be called only by the chairman of the board of directors or a
majority of the board of directors. These provisions could have the effect of
delaying until the next annual meeting of stockholders those actions that are
favored by the holders of a majority of our outstanding voting securities.
These provisions may also discourage another person from making a tender offer
for our common stock, because that person, even if it acquired a majority of
our outstanding voting securities, would be able to take action as a
stockholder, such as electing new directors or approving a merger, only at a
duly called meeting of stockholders and not by written consent.

   Advance Notice Requirements for Stockholder Proposals and Directors
Nominations. Our bylaws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for
election as directors at an annual meeting of stockholders, must provide timely
notice thereof in writing.

                                       85
<PAGE>


To be timely, a stockholder's notice must be received at our principal
executive offices not less than 90 days nor more than 120 days prior to the
anniversary date of the immediately preceding annual meeting of stockholders.
In the event that the annual meeting is called for a date that is not within 30
days before or after the anniversary date, in order to be timely, notice from
the stockholder must be received no later than the tenth day following the date
on which notice of the annual meeting was mailed to stockholders or made
public, whichever occurred earlier. Our bylaws also specify requirements as to
the form and content of a stockholder's notice. These provisions may preclude
stockholders from bringing matters before an annual meeting of stockholders or
from making nominations for directors at an annual meeting of stockholders.

   Authorized but Unissued Shares. The authorized but unissued shares of common
stock and preferred stock are available for future issuance without approval of
the holders of Class A or Class C common stock. As described above, the vote of
the holders of the Class B common stock, voting separately as a class, is
required to issue equity securities in excess of specified limits. These
additional shares may be utilized for a variety of corporate purposes,
including future public offerings to raise additional capital, corporate
acquisitions and employee benefit plans. The existence of authorized but
unissued shares of common stock and preferred stock could render more difficult
or discourage an attempt to obtain control of us by means of a proxy contest,
tender offer, merger or otherwise.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is EquiServe.

                 IMPORTANT UNITED STATES TAX CONSEQUENCES
                  TO NON-U.S. HOLDERS OF CLASS A COMMON STOCK

   This section is a general discussion of important United States federal
income and estate tax consequences of the ownership and disposition of our
Class A common stock by a non-U.S. holder. You are a non-U.S. holder if you
are, for United States federal income tax purposes:

  . a non-resident alien individual;

  . a foreign corporation;

  . a foreign partnership; or

  . an estate or trust that in either case is not subject to United States
    federal income tax on a net income basis on income or gain from Class A
    common stock.

   We do not, however, discuss all aspects of United States federal taxation
that may be important to a particular non-U.S. holder in light of specific
facts and circumstances relevant to that non-U.S. holder. For example this
section does not describe special tax rules that could apply to a non-U.S.
holder who was previously a U.S. resident or citizen. This section also does
not address the treatment of a non-U.S. holder under the laws of any state,
local or foreign taxing jurisdiction. This section is based on the tax laws of
the United States, including the Internal Revenue Code of 1986, as amended,
existing and proposed regulations, and administrative and judicial
interpretations, all as currently in effect. These laws are subject to change,
possibly on a retroactive basis.

   You should consult a tax advisor regarding the United States federal tax
consequences of acquiring, holding and disposing of Class A common stock in
your particular circumstances, as well as any tax consequences that may arise
under the laws of any state, local or foreign taxing jurisdiction

Dividends

   Except as described below, if you are a non-U.S. holder of Class A common
stock, dividends paid to you are subject to withholding of United States
federal income tax at a 30% rate or at a lower rate if you are eligible for the
benefits of an income tax treaty that provides for a lower rate. Under
currently effective United States Treasury regulations, for purposes of
determining if dividends are subject to the 30% withholding tax, dividends paid
to an address in a foreign country are presumed to be paid to a resident of
that country, unless the person making the payment has knowledge to the
contrary. Under current interpretations of United States Treasury regulations,
this presumption also applies for purposes of determining whether a lower
withholding rate applies under an income tax treaty.

   Under United States Treasury regulations that will generally apply to
dividends paid after December 31, 2000, you must satisfy certification
requirements in order to claim the benefit of a lower treaty rate.
Additionally, if you are a partner in a foreign partnership, you, in addition
to the foreign partnership, must satisfy the certification requirements and the
partnership must provide information as well. The Internal Revenue Service will
apply a look-through rule in the case of tiered partnerships.

   If you are eligible for a reduced rate of United States withholding tax
under a tax treaty, you may obtain a refund of any amounts withheld in excess
of that rate by filing a refund claim with the United States Internal Revenue
Service.

   If the dividends are "effectively connected" with your conduct of a trade or
business within the United States, and, if required by a tax treaty, the
dividends are attributable to a permanent establishment that you maintain in
the United States, then the dividends generally are not subject to withholding
tax. Instead, "effectively connected" dividends are taxed at rates applicable
to United States citizens, resident aliens and domestic United States
corporations.

                                       87
<PAGE>

   If you are a corporate non-U.S. holder, "effectively connected" dividends
that you receive may be subject to an additional "branch profits tax" at a 30%
rate or at a lower rate if you are eligible for the benefits of an income tax
treaty that provides for a lower rate.

Gain on Disposition of Class A Common Stock

   If you are a non-U.S. holder, you generally will not be subject to United
States federal income tax on gain that you recognize on a disposition of Class
A common stock unless:

  . the gain is "effectively connected" with your conduct of a trade or
    business in the United States, and the gain is attributable to a
    permanent establishment that you maintain in the United States, if that
    is required by an applicable income tax treaty as a condition for
    subjecting you to United States taxation on a net income basis;

  . you are an individual, you hold the Class A common stock as a capital
    asset, you are present in the United States for 183 or more days in the
    taxable year of the sale and other specific requirements are met; or

  . we are or have been a United States real property holding corporation for
    federal income tax purposes and you held, directly or indirectly, at any
    time during the five-year period ending on the date of disposition, more
    than 5% of the Class A common stock and you are not eligible for any
    treaty exemption.

   If you are a corporate non-U.S. holder, "effectively connected" gains that
you recognize may also, in some circumstances, be subject to an additional
"branch profits tax" at a 30% rate or at a lower rate if you are eligible for
the benefits of an income tax treaty that provides for a lower rate.

   We have not been, are not and do not anticipate becoming a United States
real property holding corporation for United States federal income tax
purposes.

Federal Estate Taxes

   Class A common stock held by an individual who is a non-U.S. holder at the
time of death will be included in the holder's gross estate for United States
federal estate tax purposes, unless an applicable estate tax treaty provides
otherwise.

Information Reporting and Backup Withholding

   Under currently applicable law, if you are a non-U.S. holder, dividends paid
to you at an address outside the United States generally will not be subject to
United States information reporting requirements or backup withholding tax.
Beginning with payments made after December 31, 2000, a non-U.S. holder will be
entitled to such exemption only if the non-U.S. holder provides a Form W-8BEN
or otherwise meets documentary evidence requirements for establishing that it
is a non-U.S. holder, or otherwise establishes an exemption.

   The gross proceeds from the disposition of Class A common stock may be
subject to information reporting and backup withholding tax at a rate of 31%.
If you sell your Class A common stock outside of the United States through a
non-U.S. office of a non-U.S. broker, and the sales proceeds are paid to you
outside the United States, then United States backup withholding and
information reporting requirements generally will not apply to that payment.
However, United States information reporting, but not backup withholding, will
apply to a payment of sales proceeds, even if that payment is made outside the
United States, if you sell your Class A common stock through a non-U.S. office
of a broker that:

  . is a United States person;

                                       88
<PAGE>


  . derives 50% or more of its gross income in specific periods from the
    conduct of a trade or business in the United States;

  . is a "controlled foreign corporation" as to the United States; or

  . with respect to payments made after December 31, 2000, is a foreign
    partnership, if at any time during its tax year:

    - one or more of its partners are U.S. persons, as defined in United
      States Treasury regulations, who in the aggregate hold more than 50%
      of the income or capital interests in the partnership;

    - at any time during its tax year, the foreign partnership is engaged in
      a United States trade or business,

unless the broker has documentary evidence in its files that you are a non-U.S.
person or you otherwise establish an exemption.

   If you receive payments of the proceeds of a sale of Class A common stock to
or through a United States office of a broker, the payment is subject to both
United States backup withholding and information reporting unless you certify,
under penalties of perjury, that you are a non-U.S. person or you otherwise
establish an exemption.

   You generally may obtain a refund of any amounts withheld under the backup
withholding rules that exceed your income tax liability by filing a refund
claim with the United States Internal Revenue Service.

                        SHARES ELIGIBLE FOR FUTURE SALE

   The sale of a substantial amount of our Class A common stock, including
shares issued upon exercise of outstanding options to purchase Class A common
stock, in the public market after this offering could adversely affect the
prevailing market price of our Class A common stock. Furthermore, because no
shares of Class A common stock will be available for sale shortly after this
offering due to the contractual restrictions on resale described in the section
entitled "Underwriting" and the legal restrictions on resale described below,
the sale of a substantial amount of common stock in the public market after
these restrictions lapse could adversely affect the prevailing market price of
our Class A common stock and our ability to raise equity capital in the future.

   Upon completion of this offering, we will have outstanding an aggregate of
173,913,000 shares of our Class A common stock and 18,256,000 shares of Class B
common stock. The Class B common stock is convertible into 800 million shares
of Class A common stock or Class C common stock as described elsewhere in this
prospectus. The Class C common stock is convertible into shares of Class A
common stock. All of the 173,913,000 shares of our Class A common stock sold in
this offering will be freely tradable without restriction or further
registration under the Securities Act, unless the shares are purchased by
"affiliates" as that term is defined in Rule 144 under the Securities Act. Any
shares purchased by an affiliate may not be resold except pursuant to an
effective registration statement or an applicable exemption from registration,
including an exemption under Rule 144 of the Securities Act. The shares of
Class A common stock issuable upon conversion of the Class A common stock or
Class C common stock will be "restricted securities" as that term is defined in
Rule 144 under the Securities Act. These restricted securities may be sold in
the public market only if they are registered or if they qualify for an
exemption from registration under Rule 144 or Rule 701 under the Securities
Act. All of the shares of Class B common stock are subject to lock-up
agreements as described more fully in the section entitled "Underwriting".

Stock Options

   Immediately after the completion of this offering, there will be options to
purchase approximately 50 million shares of our Class A common stock
outstanding under our long-term incentive plans. Shortly after the completion
date of this offering, we expect to file a registration statement under the
Securities Act covering the 90 million shares of Class A common stock reserved
for issuance under our long-term incentive plans. The shares of our Class A
common stock registered under this registration statement would be immediately
available for sale in the open market, subject to vesting restrictions for
these options and the lock-up agreements.

them, the number of shares indicated below:

</TABLE>

   The underwriters are offering the shares of Class A common stock subject to
their acceptance of the shares from us and subject to prior sale. The
underwriting agreement provides that the obligations of the underwriters to pay
for and accept delivery of the shares of Class A common stock offered by this
prospectus are subject to various conditions. The underwriters must take and
pay for all of the shares of Class A common stock offered by this prospectus if
any of these shares are taken. However, the underwriters are not required to
take or pay for the shares covered by the underwriters' over-allotment option
described below.

   The underwriters initially propose to offer part of the shares of Class A
common stock directly to the public at the public offering price listed on the
cover page of this prospectus and part to dealers at a price that represents a
concession not in excess of $    a share under the public offering price. Any
underwriter may allow, and dealers may reallow, a concession not in excess of
$    a share to other underwriters or to dealers. After the initial offering of
the shares of Class A common stock, the offering price and other selling terms
may from time to time be varied by the representatives of the underwriters.

   We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to an aggregate of 26,087,000
additional shares of Class A common stock at the public offering price listed
on the cover page of this prospectus, less underwriting discounts and
commissions. The underwriters may exercise this option solely for the purpose
of covering overallotments, if any, made in connection with the offering of the
shares of Class A common stock offered by this prospectus. To the extent the
option is exercised, each underwriter will become obligated, subject to
conditions, to purchase about the same percentage of the additional shares of
Class A common stock as the number listed next to the underwriter's name in the
preceding table bears to the total number of shares of Class A common stock
listed next to the names of all underwriters in the preceding table. If the
underwriters exercise the option in full, the total price to the public would
be $   , the total underwriters' discounts and commissions would be $    and
total proceeds to us would be $   .

   The underwriters have informed us that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Class A common stock offered by them.

   We have applied to have our Class A common stock listed on the Nasdaq
National Market under the symbol "GENU".

   Each of Genuity, the directors and executive officers of Genuity, the
persons purchasing shares of our Class A common stock in the directed share
program and GTE has agreed that, without the prior written consent of Morgan
Stanley & Co. Incorporated and Salomon Smith Barney Inc. on behalf of the
underwriters, it will not, during the period ending 180 days after the date of
this prospectus:

  . offer, pledge, sell, contract to sell, sell any option or contract to
    purchase, purchase any option or contract to sell, grant any option,
    right or warrant to purchase, lend or otherwise transfer or dispose of

                                       91
<PAGE>

    directly or indirectly, any shares of Class A common stock or any
    securities convertible into or exercisable or exchangeable for Class A
    common stock; or

  . enter into any swap or other arrangement that transfers to another, in
    whole or in part, any of the economic consequences of ownership of the
    Class A common stock;

whether any transaction described above is to be settled by delivery of Class A
common stock or such other securities, in cash or otherwise. The restrictions
described in this paragraph do not apply to:

  . the sale of shares to the underwriters;

  . our issuance of shares of Class A common stock upon the exercise of an
    option or a warrant or the conversion of a security outstanding on the
    date of this prospectus of which the underwriters have been advised in
    writing; or

  . transactions by any person other than us relating to shares of Class A
    common stock or other securities acquired in open market transactions
    after the completion of the offering of the shares.

The representatives of the underwriters may also waive the restrictions
described above in their discretion.

   In order to facilitate the offering of the Class A common stock, the
underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of the Class A common stock. Specifically, the underwriters
may over-allot in connection with the offering, creating a short position in
the Class A common stock for their own account. In addition, to cover over-
allotments or to stabilize the price of the Class A common stock, the
underwriters may bid for, and purchase, shares of Class A common stock in the
open market. Finally, the underwriting syndicate may reclaim selling
concessions allowed to an underwriter or a dealer for distributing the common
stock in the offering, if the syndicate repurchases previously distributed
common stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the common stock above independent market
levels. The underwriters are not required to engage in these activities, and
may end any of these activities at any time.

   We and the underwriters have agreed to indemnify each other against
liabilities, including liabilities under the Securities Act.

Directed Share Program

   At our request, the underwriters have reserved for sale, at the initial
offering price, up to 8,695,650 shares of our Class A common stock offered by
this prospectus. The number of shares of Class A common stock available for
sale to the general public will be reduced to the extent such persons purchase
such reserved shares. Any reserved shares that are not so purchased will be
offered by the underwriters to the general public on the same basis as the
other shares offered hereby.

Pricing of the Offering

   Prior to this offering, there has been no public market for the Class A
common stock. The initial public offering price will be determined by
negotiations between us and the representatives of the underwriters. The
factors to be considered in determining the initial public offering price will
include the future prospects of our company and its industry in general, sales,
earnings and other financial operating information of our company in recent
periods, and the price-earnings ratios, price-sales ratios, market prices of
securities and some financial and operating information of companies engaged in
activities similar to those of our company. The estimated initial public
offering price range indicated on the cover page of this preliminary prospectus
is subject to change as a result of market conditions and other factors.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholder of Genuity Inc.:

   We have audited the accompanying combined balance sheets of Genuity Inc.
(comprised of certain operations of Genuity Inc. and wholly-owned by GTE
Corporation (GTE)) (the Company) as of December 31, 1998 and 1999, and the
related combined statements of operations, changes in stockholder's equity,
cash flows and comprehensive loss for each of the three years in the period
ended December 31, 1999. We have also audited the statements of operations,
changes in shareholder's equity, cash flows and comprehensive loss of the
Company's predecessor for the six months ended June 30, 1997, the period prior
to the acquisition by the Company. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting amounts and disclosures in the financial statements.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Company as of December
31, 1998 and 1999, and the results of its operations and its cash flows for
each of the three years in the period ended December 31, 1999 and the results
of operations and cash flows of the Predecessor for the six months ended June
30, 1997 in conformity with accounting principles generally accepted in the
United States.

   Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule is presented
for purposes of complying with the Securities and Exchange Commission's rules
and is not part of the basic financial statements. This schedule has been
subjected to the auditing procedures applied in the audit of the basic
financial statements and, in our opinion, fairly states in all material
respects the financial data required to be set forth therein in relation to the
basic financial statements taken as a whole.

             (Including Data Applicable to Unaudited Periods)

1.Description of Business and Summary of Significant Accounting Policies:

Description of Business and Organization

   Genuity Inc. (Genuity or the Company), a Delaware corporation, is a wholly-
owned subsidiary of GTE Corporation (GTE). Genuity is a leading facilities-
based provider of managed Internet infrastructure services. By leveraging a
technologically advanced, high-bandwidth global fiber-optic network, data
center facilities, and a rapidly growing base of business and consumer users
and content directly attached to its Internet backbone, Genuity engineers and
delivers a comprehensive suite of managed Internet infrastructure services.
These services include Internet access through dial-up, dedicated and digital
subscriber lines; web hosting and content delivery; and value added e-business
services, such as virtual private networks for secure data transmission,
security services and voice-over-IP. Genuity's services are provided to both
enterprises and service providers including Internet service providers,
application service providers and carriers.

   Genuity's predecessor incurred net losses of $37.7 million for the six
months ended June 30, 1997. Genuity incurred net losses of $174.9 million,
$468.6 million and $647.0 million for the years ended December 31, 1997, 1998
and 1999, respectively, and $138.6 million and $209.8 million for the three
months ended March 31, 1999 and 2000 (unaudited), respectively. Through March
31, 2000, Genuity has incurred cumulative operating losses of $1,516.7 million
(unaudited). Given the level of planned operating and capital expenditures,
Genuity expects to continue to incur significant operating losses for the next
several years.

   The markets in which Genuity operates can be characterized as rapidly
changing due to technological developments, evolving industry standards and
customer demands and frequent new product and service introductions and
enhancements. Genuity expects to continue to make significant investments to
expand its capacity and facilities infrastructure, develop brand recognition,
broaden the range of service offerings and expand its sales, marketing,
technical and customer support personnel. These efforts will require
significant expenditures, a substantial portion of which will be made before
any significant corresponding revenue may be realized.

   Genuity is also dependent on a limited source of suppliers for a number of
components and parts necessary for its network buildout and operations. Genuity
does not carry significant inventories of components and has no guaranteed
supply arrangements with vendors. Shortages from these suppliers could cause
significant delays in or abandonment of the expansion of the network and could
have an adverse affect on Genuity's operating results.

Basis of Presentation

   The accompanying combined financial statements of Genuity include the
financial position and results of operations of those operations that will
constitute Genuity as of the completion of the proposed initial public
offering. Certain of the operations and assets included in these combined
financial statements were transferred to Genuity on      , 2000. The
accompanying financial statements have been restated to combine the assets,
liabilities, equity and results of operations of these transferred operations
as if the transfer had occurred as of January 1, 1997. GTE acquired BBN
Corporation effective June 30, 1997. This acquisition was accounted for as a
purchase business combination and, consequently, the results of operations of
BBN Corporation, excluding the operations of BBN Technologies (BBNT), which are
being retained by GTE, are included in the Genuity financial statements for the
periods after June 30, 1997. The results of operations of our predecessor
represent the results of BBN Corporation, excluding the operations of BBNT.

   Genuity prepares its combined financial statements in accordance with
generally accepted accounting principles, which require that management make
estimates and assumptions that affect reported amounts. Actual results could
differ from these estimates.

                                  GENUITY INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)


   The combined financial statements of Genuity include the accounts of all
majority-owned subsidiaries. All significant intercompany amounts have been
eliminated.

   Genuity purchases payroll, purchasing, electronic data processing services
and other general and administrative services from GTE and affiliates whose
business is the provision of these services. In management's view, the cost of
services provided to Genuity by GTE and affiliates reasonably approximates the
costs that Genuity would have incurred if it had performed the services. See
Note 13 for further discussion.

Interim Financial Statements

   The accompanying combined financial statements as of March 31, 2000, and for
the three-month periods ended March 31, 1999 and 2000, are unaudited, but in
the opinion of management, include all adjustments consisting of normal
recurring adjustments necessary for a fair presentation of results for the
interim periods. Certain information and footnote disclosures normally included
in financial statements prepared in accordance with generally accepted
accounting principles have been omitted with respect to the quarters, although
the Company believes that the disclosures included are adequate to make the
information presented not misleading. Results for the three months ended March
31, 2000 are not necessarily indicative of the results that may be expected for
the year ending December 31, 2000.

Revenue Recognition

   Revenue is generally recognized when services are rendered or products are
delivered to customers. The majority of Genuity's contracts consist of separate
agreements to provide Internet access, web-hosting, value added e-business or
transport services to customers.

 Access

   Internet access services include dial-up, dedicated and digital subscriber
lines. Internet access customers typically sign one or two-year contracts
providing for monthly recurring service fees that are earned and recognized
based on either fixed fees or capacity utilization. Access also includes
revenue associated with the development, operation and maintenance of a
nationwide dial-up network for America Online, based on a fee per modem per
month basis. The contract with America Online extends through 2006.

 Web-Hosting

   Web-hosting services include managed hosting, collocation, content delivery
and high availability services. Web-hosting customers typically sign one or
two-year contracts. Revenues are earned and recognized based on monthly fees
for server management, physical facilities and bandwidth utilization.

 Transport

   Transport services include services such as asynchronous transfer mode, or
ATM, and private line services. ATM transfer service, a form of high speed data
transfer, is targeted primarily at carriers and Internet service providers with
high bandwidth voice, video and data transmission requirements. Private line
service provides dedicated point-to-point transport services through non-
switched, non-usage sensitive dedicated facilities. Transport revenues are
earned and recognized based on customer usage of circuit mileage and capacity.
Transport customers typically sign one or two-year contracts.

 Other

   Other includes the results of the international business, which consists
primarily of Internet access, and domestic value-added e-business services,
such as managed security services, virtual private networks for

                                      F-9

                                  GENUITY INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)

secure data transmission and voice-over-IP. Revenues for international access
and hosting are recognized on a basis consistent with domestic services.
Revenues for security and virtual private network services are earned and
recorded based on fixed, monthly recurring fees and revenues for voice-over-IP
services are based on usage. Value-added e-business service contracts typically
range from one to two years.

   Billings made or payments received in advance of providing services are
deferred until the period these services are provided.

   Certain of Genuity's contracts, primarily related to web hosting and value
added e-business services, include up-front charges for installation services.
It has been the Company's practice to recognize installation revenue only to
the extent of incurred costs. In the first quarter of 2000, the Company adopted
Staff Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial
Statements." In accordance with SAB No. 101, as amended, this revenue and the
corresponding costs are deferred and recognized over the contract terms, which
approximate 1 year.

   Genuity has contracts with some customers that provide service level
commitments. If Genuity does not meet the required service levels, it may be
obligated to provide credits, usually in the form of free service for a short
period of time. These amounts are accounted for in cost of sales. To date,
credits issued under these arrangements for Genuity's failure to meet service
level commitments have not been material. During 1999, one of Genuity's vendors
experienced failures on its network, which resulted in a disruption to
Genuity's customers. Genuity's vendor provided credits to Genuity for the
service failure, which Genuity passed on to its customers.

Advertising Costs

   Genuity expenses the cost of advertising as incurred. The Predecessor's
advertising expense was $5.1 million for the six months ended June 30, 1997.
Genuity's advertising expense was $4.6 million, $16.5 million and $21.5 million
for the years ended December 31, 1997, 1998 and 1999, respectively, and $2.8
million and $6.6 million for the three-month periods ended March 31, 1999 and
2000 (unaudited), respectively. Advertising expense is included as a component
of selling, general and administrative expenses in the accompanying combined
statements of operations.

Income Taxes

   Genuity has historically filed its federal income tax return on a
consolidated basis with GTE. Upon completion of the proposed initial public
offering, Genuity will be deconsolidated from GTE for income tax return
purposes. Income tax payments and refunds will be determined based on the
stand-alone filings of Genuity. The accompanying combined financial statements
are presented as if Genuity was a stand-alone company for all periods
presented. The Predecessor was part of a stand-alone entity, and its taxes were
recorded on that basis.

   Genuity and the Predecessor computed their current and deferred income tax
expense on a stand-alone basis in accordance with Statement of Financial
Accounting Standards (SFAS) No. 109 "Accounting for Income Taxes," which
requires recognition of deferred tax liabilities and assets based upon the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax
liabilities and assets are determined based on the difference between the
financial statement and tax basis of assets and liabilities using tax rates in
effect for the year in which the differences are expected to reverse. A
valuation allowance has been established to reflect the likelihood of
realization of deferred tax assets.

                                  GENUITY INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)

   Genuity has approximately $39 million of net operating loss carryforwards
and $10 million of research credit carryforwards, which are limited in use due
to the fact that they were generated by the Predecessor.

Loss Per Common Share

   Loss per common share is calculated based on the provisions of SFAS No. 128,
"Earnings per Share." The basic loss per share of Genuity was computed based on
the number of common shares that were issued in connection with the
recapitalization of Genuity, which occurred on     , 2000. Genuity has no
potentially dilutive common shares.

Cash and Cash Equivalents

   Cash and cash equivalents include investments in short-term, highly liquid
securities, which have maturities when purchased of three months or less.

Deferred Commissions

   Genuity defers certain customer acquisition costs in order to recognize
those direct costs in the same accounting period as the associated revenues,
provided the revenues are contractual. These deferred costs were included in
other current assets in the accompanying combined balance sheets.

Property, Plant and Equipment

   Property, plant and equipment are stated at cost less accumulated
depreciation and amortization. Depreciation is computed over the assets'
estimated useful lives using the straight-line method. Useful lives used in
computing depreciation are as follows: buildings and fixtures--10 to 30 years,
communications network--fiber-optic cable--20 to 25 years, communications
network--data processing equipment and machinery which include labor and other
direct costs--3 to 10 years and furniture--5 to 7 years. Leasehold improvements
are amortized over the shorter of the lease period or their estimated useful
lives using the straight-line method. Maintenance and repairs are charged to
expense as incurred; improvements are capitalized.

   When property is sold or retired, the cost of the property and the related
accumulated depreciation are removed from the combined balance sheet and any
gain or loss on the transaction is included in the accompanying combined
statement of operations.

   Work in progress represents costs incurred for the build-out and expansion
of the network infrastructure and includes engineering costs and capitalized
interest. When these assets are placed in service, the costs are recorded in
the appropriate property, plant and equipment accounts and depreciation begins.

   Genuity leases data communications equipment under a capital lease
agreement. The assets and liabilities under the capital lease are recorded at
the present value of minimum lease payments. Assets under the capital lease are
depreciated over the term of the lease, which is generally 5 years.

   Communications network--fiber optic cable primarily includes an indefeasible
right of use agreement with Qwest Communications International Inc. at December
31, 1999 and March 31, 2000 (unaudited).

Goodwill and Other Intangibles

   Goodwill and other intangible assets pertain to the acquisitions of the
Predecessor and the assets of a web hosting business acquired in 1997, and
internal use software. Goodwill is being amortized on a straight-line basis
over the lesser of 20 years or the period benefited. Other intangible assets
include customer bases,

                                      F-11

                                  GENUITY INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)

trademarks, developed technology and in-place work forces in connection with
the acquisitions, and internal use software. Customer bases and in-place work
forces are amortized in a manner consistent with historical attrition patterns
over 3 to 10 years. Trademarks, developed technology and internal use software
are amortized on a straight-line basis over 3 to 10 years.

Software

   In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." Under the provisions of this
SOP, effective January 1, 1999, Genuity was required to capitalize and amortize
the cost of all internal-use software. Prior to the adoption of SOP 98-1,
primarily all software was expensed as incurred. Software expensed in 1997 and
1998 was approximately $17.3 million and $1.4 million, respectively.
Capitalized software is amortized over a useful life ranging from 3 to 5 years.
Software maintenance costs are expensed as incurred.

Employee Benefit Plans

   For periods prior to the initial public offering, Genuity participated in
GTE's pension and postretirement health care and life insurance benefit plans.
The plans' cost and liability recorded by Genuity are based on Genuity's
participation in GTE's plans.

Valuation of Assets

   The impairment of tangible and intangible assets is assessed when changes in
circumstances indicate that their carrying value may not be recoverable. Under
SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-
Lived Assets to Be Disposed Of," a determination of impairment, if any, is made
based on estimated future cash flows, salvage value or expected net sales
proceeds depending on the circumstances. In instances where goodwill has been
recorded in connection with impaired assets, the carrying amount of the
goodwill is first eliminated before any reduction to the carrying value of
tangible or identifiable intangible assets. Genuity's policy is to record asset
impairment losses as well as net gains or losses on sales of assets as a
component of other income. Under Accounting Principles Board Opinion No. 17,
"Intangible Assets," the Company also annually evaluates the future period over
which the benefit of goodwill will be received, based on future cash flows, and
changes the amortization life accordingly.

Concentrations of Credit Risk and Significant Customers

   Genuity's accounts receivable are subject to credit risk. Genuity performs
regular credit evaluations of its customers' financial condition and maintains
allowances for potential credit losses. Genuity's risk of loss is limited due
to advance billings to some of its customers for services and the ability to
terminate service on delinquent accounts. The credit risk is also mitigated by
the large number of customers comprising the customer base, with the exception
of one large customer, America Online. Revenues from America Online in relation
to Genuity's and Predecessor's total revenues were significant. However, the
credit risk associated with America Online is mitigated by utilization of
advance billings and a history of timely collections. The average accounts
receivable balance of America Online represented 34%, 44% and 37% of Genuity's
receivable balance during the years ended 1998 and 1999, and the three-months
ended March 31, 2000 (unaudited),

                                      F-12

                                  GENUITY INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)

respectively, while revenues from America Online represented 53% and 52% of
Genuity's total revenues for the years ended December 31, 1998 and 1999,
respectively, and 53% and 46% for the three-month periods ended March 31, 1999
and 2000 (unaudited), respectively.

   Genuity has been a supplier of network access services in the United States
to America Online since 1995. Genuity entered into a new agreement with America
Online effective as of December 31, 1999, pursuant to which America Online has
agreed to purchase additional dial-up access services from Genuity for a seven-
year term through December 31, 2006. Under the new agreement, America Online
has also agreed to purchase managed digital subscriber line and other broadband
network access services from Genuity for a five-year term through December 31,
2004. This agreement includes provisions for minimum purchase requirements at
fixed monthly fees, subject to market pricing adjustments, service level
requirements and termination provisions.

   In providing America Online services under the agreement, Genuity is
obligated to comply with specified minimum service levels. Either party may
terminate the agreement in the event the other party commits a material breach
which is not cured within the specified period. In addition, America Online has
the right to terminate the agreement in the event of: (1) repeated material
breaches by Genuity; (2) a violation of the most favored customer pricing
provisions; (3) a total or near total outage of any of the services provided by
Genuity that, while lasting fewer than thirty days, is widespread and
prolonged; (4) Genuity's inability to meet the service level commitments or to
expand service availability as required under the agreement; and (5) a change
in control other than through an initial public offering. Genuity is also
obligated to provide America Online assistance in the twelve months following
any termination of the agreement to ensure a smooth transition of services. The
agreement provides America Online with a right of first refusal with respect to
the sale of the dial-up network access business.

   Under a separate agreement with America Online Japan and Genuity's Japanese
branch, Genuity has agreed to provide dial-up network access services to
America Online in Japan. This agreement also includes minimum purchase
requirements on the part of America Online Japan, market pricing adjustments,
service level requirements, and termination provisions.

Financial Instruments

   Financial instruments include cash and cash equivalents, accounts
receivable, equity securities, accounts payable, notes payable and debt. The
fair values of financial instruments included in the combined balance sheets,
other than long-term debt, closely approximate their recorded values. The
recorded values of equity securities equal their fair values based on quoted
market prices, and are classified as available-for-sale securities. The
securities are included in other current assets in the accompanying combined
balance sheets and have a cost of $11.8 million and $3.5 million at December
31, 1998 and 1999, respectively, and $3.5 million at March 31, 2000
(unaudited). The estimated fair value of long-term debt based on a debt pricing
model was lower than its recorded value as of December 31, 1998 and 1999 by
approximately $1.2 million and $6.6 million, respectively, and as of March 31,
2000, by approximately $6.8 million (unaudited).

Comprehensive Loss

   Comprehensive loss is the change in equity from transactions and other
events and circumstances that are not from owners. Included in other
comprehensive income (loss) are foreign currency translation gains and losses
and unrealized gains and losses on available-for-sale securities.

             (Including Data Applicable in Unaudited Periods)
Foreign Currency Translation

   Assets and liabilities of units operating in foreign countries are
translated into U.S. dollars using the exchange rates in effect on the balance
sheet date. Results of operations are translated using the average exchange
rates prevailing throughout the period. Foreign assets, liabilities and results
of operations are not material in all periods presented.

Recent Accounting Pronouncements

   On December 3, 1999, the Securities and Exchange Commission issued SAB No.
101. Genuity is required to adopt this accounting guidance, as amended by SAB
No. 101A, no later than the second quarter of 2000. Genuity adopted this
accounting in the first quarter of 2000. There was no impact to the Company's
combined statement of operations for the adoption of SAB No. 101, as it had
been the Company's practice to recognize installation revenue on its web
hosting contracts only to the extent of incurred costs. The Company, at March
31, 2000, has recorded deferred revenue of approximately $1.9 million and
deferred costs of approximately $1.9 million associated with the adoption of
SAB No. 101.

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts
(collectively referred to as derivatives) and for hedging activities. SFAS No.
133, as amended by SFAS No. 137, is effective for all fiscal quarters of fiscal
years beginning after June 15, 2000. This new standard is not anticipated to
have an impact on the Company's combined financial statements based on the
current structure and operations.

2.GTE's Proposed Merger with Bell Atlantic Corporation

   Genuity is currently a wholly owned subsidiary of GTE. In July 1998, GTE and
Bell Atlantic agreed to enter into a merger of equals transaction. The new
combined company is Verizon Communications (Verizon). Under the terms of the
agreement, which was unanimously approved by the boards of directors of both
companies and a majority of the shareholders, GTE's shareholders will receive
1.22 shares of Verizon stock for each share of GTE's stock that they own. The
merger is subject to regulatory approvals.

   Under the Telecommunications Act of 1996 (Telecommunications Act), the
Regional Bell Operating Companies, including the Bell Atlantic local telephone
operating companies, and their respective affiliates, are generally prohibited
from providing long distance services that originate in any state in which the
Regional Bell Operating Companies operate an incumbent local telephone company.
These restrictions, which are referred to as Section 271 restrictions, prohibit
these companies from offering long distance services originating in a
particular state until the relevant local telephone operating company operating
in that state has satisfied a 14-point competitive checklist under Section 271
of the Telecommunications Act and obtained authority from the Federal
Communications Commission (FCC) to provide long distance services in those
states.

   Bell Atlantic operates an incumbent local telephone companies in 13 states,
from Maine to Virginia, and the District of Columbia. The total billable access
telephone lines owned by Bell Atlantic in these states in 1999 are referred to
as "Bell Atlantic in-region lines." Bell Atlantic has obtained the necessary
authorization to provide long distance service originating in New York. Because
Genuity provides services in Bell Atlantic's region that could be characterized
as long distance services, Bell Atlantic and GTE cannot complete their merger
until they

                                  GENUITY INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)

either (1) receive relief from the Section 271 restrictions for the remaining
states in which Bell Atlantic provides local telephone services or (2)
implement a structure that complies with the requirements of the
Telecommunications Act.

   To ensure compliance with the requirements of the Telecommunications Act and
to receive FCC approval of their merger, Bell Atlantic and GTE made a proposal
to the FCC under which (1) GTE would exchange all of the outstanding shares of
Genuity common stock for shares of Genuity Class B common stock and (2) Genuity
would complete an initial public offering of Class A common stock. As a result,
immediately after completion of Genuity's proposed initial public offering, the
investors purchasing shares in the initial public offering will own shares of
Genuity's Class A common stock possessing 90.5% of the total voting power of
Genuity's common stock and Verizon will own shares of Genuity's Class B common
stock possessing 9.5% of the total voting power of Genuity's common stock.

   Genuity's Class B common stock is convertible into Class A common stock or,
if held by Verizon and at Verizon's election, Class C common stock. Genuity's
Class A common stock and Class B common stock have one vote per share and
Genuity's Class C common stock has five votes per share. Under the proposal to
the FCC, Genuity's Class B common stock cannot be converted into more than 10%
of the outstanding common stock until Verizon has eliminated, as to at least
50% of the Bell Atlantic in-region lines, Section 271 restrictions applicable
to its operation of Genuity's business. At such time as Verizon has eliminated
the applicable Section 271 restrictions as to at least 50% of Bell Atlantic in-
region lines, Genuity's outstanding shares of Class B common stock can be
converted by a holder other than Verizon into 800 million shares of Genuity's
Class A common stock. This amount represents approximately 82% of Genuity's
common stock outstanding after the proposed initial public offering or 80% if
the underwriters fully exercise their over-allotment option. At such time as
Verizon has eliminated the applicable Section 271 restrictions as to 100% of
the Bell Atlantic in-region lines, it could convert its Class B common stock
into 800 million shares of Class C common stock, which, in addition to
representing approximately 82% of Genuity's common stock outstanding after the
proposed initial public offering, would also possess approximately 96% of the
total voting power of the common stock.

   During 1999, Genuity completed its initial buildout of its communications
network in the United States. Costs directly related to the network have been
capitalized, including amounts associated with the indefeasible rights of use.
Genuity commenced depreciation as individual segments were placed in service.

   The Predecessor's depreciation expense was $10.5 million for the six months
ended June 30, 1997. Genuity's depreciation expense was $18.7 million, $56.2
million and $135.4 million for the years ended December 31, 1997, 1998 and

   On April 1, 1987, Predecessor issued $84.7 million of 6% convertible
subordinated debentures. The 6% convertible subordinated debentures due 2012
may be converted by the bondholders into cash at an exchange ratio of $966.67
for each $1,000 in principal amount of debentures. The debentures are unsecured
obligations of Genuity and are subordinated in right of payment to Genuity's
senior indebtedness, if any. Debt issuance costs are being amortized over the
term of the debentures. The unamortized balance at December 31, 1999, and March
31, 2000 of $0.6 million and $0.5 million (unaudited), respectively, is
included in other assets in the accompanying combined balance sheets.

   Genuity is required to contribute to a sinking fund annual payments equal to
5% of the aggregate principal amount issued. The sinking fund was calculated to
retire 70% of the original debentures prior to maturity. As of December 31,
1999 Genuity had purchased and retired debentures with a face value of $37.3
million which has been used to satisfy the annual sinking fund requirements
through 2006.

   The interest rate on the note payable to/receivable from GTE is based on an
intercompany borrowing interest rate established by GTE, which fluctuated
between 4.85% and 6.58% in 1997, 5.41% and 6.24% in 1998, 6.04% and 6.75% in
1999, 5.00% and 5.68% in the first quarter of 1999 (unaudited) and 6.00% and
6.24% in the first quarter of 2000 (unaudited).

   Genuity has entered into leasing agreements to finance some equipment
acquisitions. The underlying assets serve to collateralize the debt. The
borrowings bear interest at effective rates of 5.07% to 9.50% and have terms of
5 years from the date of purchase, with principal and interest payable
quarterly in advance. The leases include purchase and renewal options at fair
market values. The leases are classified as capital leases in accordance with
the provisions of SFAS No. 13, "Accounting for Leases."

   Assets under capital leases were as follows (in thousands):

6.Stockholder's Equity

Common Stock

   The authorized and issued common stock of Genuity is based on the number of
common shares that will be issued in connection with the recapitalization of
Genuity, which occurred on      , 2000. In connection with the
recapitalization, the 1,000 shares of common stock issued and outstanding were
converted to 18,256,000 shares of Class B common stock.

Additional Paid-In Capital

   Genuity received contributions from GTE of $610.5 million, $1,313.6 million
and $974.3 million, for the years ended December 31, 1997, 1998 and 1999,
respectively, and $487.9 million for the three-month period ended March 31,
2000 (unaudited).

Accumulated Other Comprehensive Income (Loss)

   Accumulated other comprehensive income (loss) includes cumulative foreign
currency translation adjustments and the cumulative unrealized loss on
investments in securities. The Predecessor's cumulative foreign currency
translation adjustment was a loss of $0.1 million as of June 30, 1997.
Genuity's cumulative foreign currency translation adjustment was a gain of $0.1
million as of December 31, 1999, and $0.8 million and $0.7 million as of March
31, 1999 and 2000 (unaudited), respectively. The Predecessor's cumulative
unrealized loss on investments in securities was $0.9 million as of June 30,
1997 and Genuity's cumulative unrealized gain on investments in securities was
$2.1 million, $3.9 million and $2.6 million as of December 31, 1997, 1998 and
1999, respectively, and $2.9 million and $1.1 million as of March 31, 1999 and
2000 (unaudited), respectively.

7.Stock-Based Compensation

   GTE maintains broad-based stock option plans that have historically covered
substantially all Genuity employees. Genuity employees will not participate in
these plans after the initial public offering. Prior to 1997, options were
granted separately or in conjunction with stock appreciation rights (SARs).
Beginning in 1997, the granting of SARs was discontinued. In 1997, GTE's
shareholders approved the GTE Corporation 1997 Long-Term Incentive Plan (the
LTIP). Each option granted under the LTIP conveys the right to purchase, at
fair market value on the date of the grant, shares of GTE common stock.
Generally, options have a term of 10 years and become vested over a period not
to exceed three years. At December 31, 1999 and March 31, 2000, 1,595,984 and
1,961,045 (unaudited) options granted to Genuity employees, respectively, were
exercisable in shares of GTE common stock. Options granted under the
Predecessor's stock incentive plan were converted into GTE options or plan
participants received cash.

   In 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation." As permitted by SFAS No. 123, GTE continues to apply the
recognition and measurement provisions of Accounting Principles Board Opinion
(APB) No. 25, "Accounting for Stock Issued to Employees." In accordance with
APB No. 25, compensation expense is not recognized for stock options on the
date of grant since it is GTE's practice to grant options with an exercise
price equal to the fair market value of its common stock on the date of grant.
Under SFAS No. 123, compensation cost is measured at the grant date based on
the value of the award and is recognized over the service or vesting period.
Had compensation cost for GTE's stock options been determined under SFAS No.
123, based on the fair market value at the grant dates, pro forma net loss and
basic loss per share of Genuity would have been as follows (in thousands except
per share amounts):

   The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions for GTE options granted during the years ended December 31, 1997,
1998 and 1999: expected volatility of 18%-19.5%, expected maturities of seven
years, risk-free interest rates equal to the yield on seven-year U.S. Treasury
notes on the grant date and expected dividend yield of approximately 3%.

8.Employee Benefit Plans

   Genuity does not intend to offer a pension or other postretirement plan to
employees once its employees are no longer employees of GTE. Genuity does
intend to offer a defined contribution (401(k)) plan.

   GTE sponsors several qualified and nonqualified pension plans and other
postretirement benefit plans for its employees, which prior to the initial
public offering, include Genuity's employees. The Predecessor did not sponsor
either a pension plan or an other postretirement benefit plan. Approximately
600 of Genuity's employees are covered under defined benefit pension plans and
postretirement health care and life insurance plans. Pension plans are
generally noncontributory by plan participants. Postretirement health care
plans are generally contributory and include a limit on the portion of the cost
of benefits for recent and future retirees paid by Genuity.

   The cost and liability for the pension and other postretirement benefit
plans recorded by Genuity are based on Genuity's participation in GTE's plans,
representing an allocation of GTE's plans' assets and liabilities. Genuity's
pension expense was $0.5 million, $0.9 million and $2.6 million for the years
ended December 31, 1997, 1998 and 1999, respectively, and $0.2 million and $0.1
million for the three-month periods ended March 31, 1999 and 2000 (unaudited),
respectively. Genuity's other postretirement benefit expense was $0.2 million,
$0.4 million and $0.3 million for the years ended December 31, 1997, 1998 and
1999, respectively, and $0.1 million for the three-month period ended March 31,
1999 (unaudited). Genuity's pension liability was $2.5 million and $5.1 million
as of December 31, 1998 and 1999, respectively, and $2.0 million as of March
31, 2000 (unaudited). Genuity's other postretirement benefit liability was
$2.0 million and $2.2 million as of December 31, 1998 and 1999, respectively,
and $1.9 million as of March 31, 2000 (unaudited).

   BBN Corporation maintained the BBN Corporation Retirement Trust Agreement
(the BBN 401(k) plan), which is a 401(k) plan that includes matching and profit
sharing features. The plan covers most employees of Genuity who are not covered
by the GTE Savings Plan. It is anticipated that the plan will be sponsored and
maintained by Genuity or one of its affiliates after the proposed initial
public offering. GTE sponsors employee savings and stock ownership plans (the
GTE 401(k) plans) under section 401(k) of the Internal Revenue Code. Through
the date of the proposed initial public offering the plans cover substantially
all full-time employees of Genuity. Under the plans, Genuity provides matching
contributions in either cash or GTE

common stock based on qualified employee contributions. The Predecessor's
matching contribution charged to income related to the BBN 401(k) plan was
$0.6 million for the six months ended June 30, 1997. Genuity's matching
contributions charged to income related to the GTE 401(k) plans and the BBN
401(k) plan were $1.0 million, $3.1 million, and $4.8 million for the years
ended December 31, 1997, 1998 and 1999, respectively, and $0.9 million and $2.2
million for the three-month periods ended March 31, 1999 and 2000 (unaudited),
respectively.

10.Income Taxes

   The income tax accounts included in the accompanying combined balance sheets
and statements of operations are presented as if Genuity were a stand-alone
company for all periods presented. The Predecessor was part of a stand-alone
entity, and its income taxes were recorded on that basis. Taxable losses of
Genuity aggregating $114.8 million, $526.7 million and $638.2 million for the
years ended December 31, 1997, 1998 and 1999, respectively, and $179.1 million
for the three-month period ended March 31, 2000 (unaudited), have benefited GTE
in its consolidated tax return. Genuity received reimbursements aggregating
$40.4 million, $185.7 million and $223.5 million for the years ended
December 31, 1997, 1998 and 1999, respectively, and $62.5 million for the
three-month period ended March 31, 2000 (unaudited). To present Genuity's tax
provisions on a basis consistent with future periods these reimbursements have
been accounted for as capital contributions. The tax provision included in the
accompanying combined statements of operations represents the amounts owed for
state taxes.

   The net operating losses included above relate to Predecessor and are
limited in their utilization under Internal Revenue Code Section 382. A full
valuation allowance has been recorded in the accompanying combined financial
statements to offset the net deferred tax asset because its future
realizability is uncertain.

   The difference between the income tax rate computed by applying the
statutory federal income tax rate of 35% to income before income taxes and the
actual effective income tax rate is summarized as follows:

11.Segment Reporting

   Effective December 31, 1998, Genuity adopted SFAS No. 131, "Disclosure about
Segments of an Enterprise and Related Information." SFAS No. 131 establishes
standards for reporting financial information about operating segments in
annual and interim financial statements and requires restatement of prior year
information. Operating segments are defined as units of a business for which
financial information is available that is evaluated by the primary decision-
makers in determining the manner in which resources are allocated and in
assessing performance of the business.

   Genuity's operations are reported in three segments, Access, Hosting and
Transport.

   Access--Internet access pertains to a variety of global Internet access
services, including dial-up, dedicated, DSL and other broadband, by providing
and managing the underlying scaleable infrastructure. Genuity also provides a
range of customer premise equipment necessary to connect to the Internet,
including routers, channel service units/data services units, modems, software
and other products. Customers receive 24 hours per day, 7 days per week network
monitoring and technical support from Genuity's Network Operations Centers
(NOC).

   Hosting--Hosting pertains to services that allow customers to successfully
implement their e-business strategies through scaleable, reliable and secure
Web sites, which serve as their e-business storefronts. Thee-business model
enables companies to decrease sales costs; accelerate time to market; access
new sales channels; increase revenues, productivity and customer satisfaction;
and gain competitive advantage. Genuity currently operates ten global data
centers, eight in the US, one in Leeds, England and one in Tokyo, Japan.
Through the web hosting operation center, Genuity monitors these systems 24
hours a day and 7 days a week.

   Transport--Genuity provides a broad range of transport services to customers
through a single point of contact for planning, ordering, installing, billing,
maintaining and managing our customers transport services. Genuity provides
seamless operation of local loops, central office connections and interexchange
carrier transport. Through Genuity's NOC, network faults, intrusion or
environmental alarms are observed, diagnostics are performed, and referrals or
dispatches are initiated as needed.

   Other--Includes revenue from international operations, sale of international
services and revenue generated from value-added Internet services of security,
virtual private networks and voice-over IP.

   Network costs within GNI which are incurred to support the Access, Hosting
and Transport segments are not allocated to these segments for management
reporting or segment reporting purposes. Similarly, selling, general and
administrative expenses are not allocated to the segments for management or
segment reporting purposes.

   Revenues for America Online in relation to the Predecessor's total revenues
represented 54% for the six months ended June 30, 1997. Revenues for America
Online in relation to Genuity's total revenues were 42%, 53% and 52% for the
years ended December 31, 1997, 1998 and 1999, respectively, and 53% and 46% for
the three-month periods ended March 31, 1999 and 2000 (unaudited),
respectively.

   Management utilizes several measurements to evaluate its operations and
allocate resources. However, the principal measurements are consistent with
Genuity's financial statements. The accounting policies of the segments are the
same as those described in Note 1.

12.Commitments and Contingencies

Leases

   Genuity leases office space and network equipment under long-term capital
and operating leases. These leases have options for renewal with provisions for
increased rent upon renewal. The Predecessor's rent expense was $2.1 million
for the six months ended June 30, 1997, and Genuity's rent expense was $5.1
million, $12.9 million and $19.9 million for the years ended December 31, 1997,
1998 and 1999, respectively, and $3.7 million and $6.6 million for the three-
month periods ended March 31, 1999 and 2000 (unaudited), respectively. Rent
expense is included in cost of goods sold and selling, general and
administrative expenses in the accompanying combined statements of operations.

   As of December 31, 1999, future minimum lease payments under noncancelable
capital and operating leases with initial or remaining periods in excess of one
year were as follows (in thousands):

Contract Commitments

   Genuity has entered into several agreements for indefeasible rights of use
(IRU) for its network infrastructure in the United States. The initial terms of
the IRUs are for 20-25 years, with options to extend the term. As of December
31, 1999 and March 31, 2000, the outstanding commitments under the agreements
is approximately $17.4 million and $16.6 million, respectively. Genuity is also
obligated to pay operating and maintenance costs under the contract terms.

   Genuity has entered into a number of agreements for IRU to trans-oceanic
cable systems that are either deployed or in the process of being deployed. The
initial terms of the IRU is for 25 years. As of December 31, 1999 and March 31,
2000, outstanding commitments under these agreements total approximately $54.4
million and $52.5 million (unaudited), respectively.

   Genuity has a noncancelable long-term purchase commitment with a circuit
provider. The purchase agreement contains provisions that require Genuity to
purchase a minimum amount of services annually through 2003. If Genuity does
not purchase the minimum services, it is required to pay the amount of the
shortfall between the minimum commitments and actual purchases. As of December
31, 1999, future minimum circuit payments under this noncancelable purchase
commitment were as follows (in thousands):

Contingencies

   Some claims arising in the ordinary course of business are pending against
the Company. In the opinion of management, these claims are without merit and
are not expected to have a material effect on operations.

13.Related Party Transactions

   Genuity recorded revenues for transport services that it provided to
affiliates in the amount of $13.6 million, $17.5 million and $24.1 million for
the years ended December 31, 1997, 1998 and 1999, respectively, and $5.5
million and $11.7 million for the three-month periods ended March 31, 1999 and
2000 (unaudited), respectively. The transport services provided are similar to
services provided to unaffiliated customers and are priced at comparable rates.

   Genuity purchases payroll, purchasing, electronic data processing services
and other general and administrative services from GTE and affiliates whose
business is the provision of these services. The cost of these services to
Genuity was $39.6 million, $92.3 million and $84.1 million for the years ended
December 31, 1997, 1998 and 1999, respectively, and $25.2 million and $21.2
million for the three-month periods ended March 31, 1999 and 2000 (unaudited),
respectively, and were based on the cost of providing these services as
determined by cost and time studies performed periodically.

   In management's view, the cost of services provided to Genuity by GTE and
affiliates reasonably approximates the costs that Genuity would have incurred
if it had performed the services.

   Note payable to, and receivable from GTE include GTE funding of net cash
flows to and from Genuity. Accounts receivable from, and accounts payable to
affiliates represent balances from transactions in the ordinary course of
business between Genuity and affiliates.

Transition Services Agreements

   GTE and its affiliates currently provide a range of administrative and
support services to Genuity. In connection with the proposed initial public
offering of Genuity's shares of Class A common stock, Genuity will enter into
(1) an Agreement for Transition Services under which GTE Service will continue
to provide Genuity with services such as accounting and cash processing,
billing and collection processing, human resource services, benefits
administration and real estate support services and (2) an Agreement for
Information Technology Transition Services under which Genuity and GTE Service
will provide each other with software and hardware support services.

              (Including Data Appliable to Unaudited Periods)

   In addition, GTE Service and Genuity will provide each other with wide area
network support and computer programming and technical services, including the
development of software interfaces and modifications and enhancements to
existing systems.

Purchase, Resale and Marketing Agreement

   Genuity plans to enter into a Purchase, Resale and Marketing Agreement under
which Verizon will purchase services from Genuity, that will include Internet
access, value-added e-business services and private line and asynchronous
transfer mode transport services. Verizon will be permitted to use these
services internally or resell the services on a stand-alone basis or as part of
a bundled solution. Those services resold by Verizon may be co-branded with
Genuity or may be branded without use of Genuity's marks. To the extent Genuity
jointly markets services with Verizon, Genuity will do so in compliance with
all applicable federal law. Genuity will not jointly market its services with
Verizon in states in which Verizon would not have legal authority under
applicable federal law to operate Genuity. Genuity has granted Verizon most
favored customer pricing and volume-based discounts. Under the terms of the
agreement, Verizon will purchase at least $500 million of Genuity's services
over a five year period. In the event that Verizon has not purchased $200
million in services by the end of the third year of the contract, it would be
required to pay to Genuity at that time the difference between the amount of
services purchased to date and $200 million. Similarly, in the event Verizon
has not purchased $500 million in services by the end of the fifth year of the
contract, it would be required to pay to Genuity at that time the difference
between the amount of services purchased to that date, including any shortfall
payment made at the end of the third year, and $500 million. The minimum
purchase commitment is reduced in the event Genuity does not comply with
various obligations as to competitive pricing and other aspects of service,
sale and delivery.

   In conjunction with the Purchase, Resale and Marketing Agreement, Genuity
also plans to provide to Verizon undersea cable capacity in the ARCOS-1
Caribbean Ring System and has committed to negotiate with Verizon with respect
to obtaining capacity on the Americas III Cable Network currently under
construction.

Intellectual Property Agreements

   Genuity intends to enter into agreements with GTE Service in order to
allocate rights relating to existing and future patents, software, other types
of intellectual property and technical services.

Network Monitoring Agreement

   Under the terms of an existing agreement, Genuity receives continual
monitoring for some elements of Genuity's network infrastructure from GTE
Network Services, including monitoring of network-enabling devices and
processes to detect anomalies occurring in the network. The fees for monitoring
services are fixed under the agreement and were negotiated based on historical
costs and comparable market prices. The agreement may be terminated by Genuity
on 90 days notice.

Real Estate Agreements

   Genuity plans to enter into several agreements with Verizon to allocate
space in various leased and owned properties between Genuity and Verizon. None
of the properties involved are material to Genuity's operations or business.
Provisions of each agreement, including the lease and sublease payment of rent
terms, vary depending on the underlying lease at the specified property and the
result of negotiations pertaining to specific issues at a specified property.

             (Including Data Applicable to Unaudited Periods)

   In order to effect a transition to a stand-alone company, GTE also has
agreed to issue new guaranties and to continue existing guaranties in order to
support Genuity's real estate obligations. GTE has agreed to continue to issue
new guaranties until six months following the proposed initial public offering
or the date on which both Standard & Poor's and Moody's publish a credit rating
for Genuity, whichever occurs first. Genuity has agreed to pay GTE a
commercially reasonable fee during the time the guaranties are in force.


Registration Rights Agreement

   Immediately after the completion of Genuity's proposed initial public
offering, under a Registration Rights Agreement dated     , 2000, Verizon and
its transferees or assignees will be entitled to cause Genuity to register
shares of Class A common stock that are issued following conversion of either
Genuity's Class B common stock or Genuity's Class C common stock. In addition,
this agreement will provide Verizon with certain demand, piggyback and shelf
registration rights after six months following the proposed initial public
offering.

14.Subsequent Events

Recapitalization

   On        , 2000, Genuity completed a recapitalization. As part of the
recapitalization, Genuity converted 1,000 shares of common stock issued and
outstanding to 18,256,000 shares of Class B common stock.

   In connection with the recapitalization, GTE will execute a recapitalization
agreement in connection with its receipt of the Class B common stock. Under
this agreement, GTE will exchange all of the shares of its Genuity common stock
for such number of shares of Class B common stock that will equal 9.5% of the
total number of shares of the common stock outstanding immediately after the
completion of this initial public offering. The recapitalization agreement also
includes provisions enabling Verizon to purchase additional shares
of Class B common stock under certain circumstances. In addition, the
recapitalization agreement contains provisions requiring us to obtain the
consent of Verizon prior to taking actions such as making acquisitions with a
purchase price exceeding 20% of Genuity's market capitalization, making any
acquisitions with a purchase price in excess of $100 million or entering any
joint venture which has a fair market value in excess of $100 million that is
not closely related to Genuity's business, making any disposition, including
the assumption of indebtedness in excess of 20% of Genuity's market
capitalization, and certain restrictions on incurring indebtedness and other
protective rights.

Common Stock

   The shares of Genuity's Class A common stock, Class B common stock and Class
C common stock are identical in all respects except for voting rights,
conversion rights and as otherwise described below. The rights, preferences and
privileges of holders of our Class A common stock, Class B common stock and
Class C common stock are subject to the rights of the holders of shares of any
other class of common stock that Genuity may authorize and issue and any series
of preferred stock that Genuity may designate and issue in the future.

   Voting Rights. Each share of Class A common stock and Class B common stock
entitles the holder to one vote on each matter submitted to a vote of the
stockholders. Each share of Class C common stock entitles the holder to five
votes on each matter. Except as required by applicable law or as discussed
below, the holders of the Class A common stock, Class B common stock and Class
C common stock vote together as a single class on all matters submitted to a
vote of Genuity's stockholders. So long as any shares of Class B common stock
remain outstanding, the holders of Class B common stock, voting separately as a
class, will have the right to elect one member of Genuity's board of directors.

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)

   Genuity is also required to obtain the consent of the holders of Class B
common stock before taking specific actions, including making significant
acquisitions or dispositions, entering into major business combinations, and
incurring indebtedness or issuing additional equity securities in excess of
specified limits.

   Conversion.  Immediately after the completion of the proposed initial public
offering, Verizon will own all of the outstanding shares of Genuity's Class B
common stock.

   Although the ability of Verizon to convert its Class B common stock is
limited by the proposal to the FCC, these shares by their terms are convertible
at any time into either:

  .  a number of shares of Class A common stock equal to 10% of Genuity's
     total common stock immediately after the conversion; or

  .  800 million shares of Class A common stock or, for Verizon or any of its
     affiliates and at their election, Class C common stock, which represents
     approximately 82% (or approximately 80% if the underwriters exercise in
     full the over-allotment option) of Genuity's shares of common stock
     outstanding immediately following the proposed initial public offering.

   Under the proposal to the FCC:

  .  if Verizon has not eliminated Section 271 restrictions applicable to its
     operation of Genuity's business as to at least 50% of the Bell Atlantic
     in-region lines, Verizon can only convert its outstanding shares of
     Genuity's Class B common stock into shares of Genuity's Class A common
     stock that after the conversion will represent 10% of Genuity's total
     common stock then outstanding. If Verizon transfers the Class B common
     stock before meeting this 50% threshold, the transferee's conversion
     rights would be similarly limited;

  .  if Verizon has eliminated the applicable Section 271 restrictions as to
     at least 50% of Bell Atlantic in-region lines, it could transfer its
     shares of Class B common stock to one or more third parties who would
     then be able to convert them in the aggregate into 800 million shares of
     Class A common stock; and

  .  if Verizon has eliminated the applicable Section 271 restrictions as to
     100% of Bell Atlantic in-region lines, subject to limited exceptions,
     Verizon or its affiliates could convert the Class B common stock into
     800 million shares of Class A common stock or Class C common stock.

   Under the proposal to the FCC, if Verizon has not eliminated the applicable
Section 271 restrictions as to 100% of Bell Atlantic in-region lines on or
before    , 2005, which date may be extended under certain conditions,
Verizon's ability to convert the Class B common stock into 800 million shares
of Class A or Class C common stock will expire. Verizon will continue to retain
its right to convert its shares of Class B common stock into shares of Class A
common stock representing 10% of Genuity's total common stock then outstanding.
If Verizon has satisfied the applicable Section 271 restrictions as to 100% of
Bell Atlantic in-region lines on or before that date, its ability to convert
the Class B common stock into 800 million shares of Class A common stock or
Class C common stock does not expire. The Class B common stock transferred by
Verizon to a third party will not be subject to this expiration limitation.



   The Class C common stock is convertible into Class A common stock at any
time. Each share of Class C common stock will automatically convert into one
share of Class A common stock if at any time the aggregate number of
outstanding shares of Class C common stock, together with any shares of Class C
common stock issuable upon conversion of Class B common stock, held by Verizon
and its affiliates constitute less than 10% of Genuity's then outstanding
common stock.

             (Including Data Applicable to Unaudited Periods)

   Verizon's Right to Acquire Additional Shares. If Verizon holds shares of
Class A common stock and Class C common stock that in the aggregate exceed 70%
of the total number of Genuity common stock, Verizon may acquire from Genuity a
number of shares of Class A common stock so that Verizon will own shares of
common stock equal to 80% of the total number of Genuity shares of common
stock.

   Liquidation. In the event of any dissolution, liquidation, or winding up of
Genuity's affairs, whether voluntary or involuntary, the holders of the Class A
common stock, the Class B common stock and the Class C common stock will be
entitled to share ratably, in proportion to the number of shares they represent
of Genuity's outstanding common stock, in the assets legally available for
distribution to stockholders, in each case after payment of all of Genuity's
liabilities and subject to preferences that may apply to any series of
preferred stock then outstanding. Genuity may not dissolve, liquidate or wind
up its affairs without obtaining the consent of the holders of the outstanding
shares of its Class B common stock.

   Mergers and Other Business Combinations. If Genuity enters into a merger,
consolidation or other similar transaction in which shares of its common stock
are exchanged for or converted into securities, cash or any other property, the
holders of each class of Genuity's common stock will be entitled to receive an
equal per share amount of the securities, cash, or other property, as the case
may be, for which or into which each share of any other class of common stock
is exchanged or converted; provided that in any such merger, consolidation or
other similar transaction, the holders of the shares of Class B common stock
shall be entitled to receive, at their election, either (1) the merger
consideration such holders would have received had they converted their shares
of Class B common stock immediately prior to the consummation of such
transaction or (2) a new security that is convertible into the merger
consideration and has substantially identical voting and other rights as the
Class B common stock. In any transaction in which shares of capital stock are
distributed, the shares that are exchanged for or converted into the capital
stock may differ as to voting rights and conversion rights only to the extent
that the voting rights and conversion rights of Class A common stock, Class B
common stock and Class C common stock differ at that time. As described above,
the holders of the Class B common stock, voting separately as a class, must
consent to any merger, consolidation or other similar transaction.

   Other Provisions. The holders of Class A common stock, Class B common stock
and Class C common stock are not entitled to preemptive rights. There are no
redemption provisions or sinking fund provisions that apply to the Class A
common stock, the Class B common stock or the Class C common stock.

   Immediately following the closing of the proposed initial public offering,
Genuity's authorized capital stock will consist of 1,600,000,000 shares of
Class A common stock, par value $0.01 per share, 21,000,000 shares of Class B
common stock, par value $0.01 per share, 800,000,000 shares of Class C common
stock, par value $0.01 per share, and 0 shares of preferred stock, par value
$0.01 per share. Immediately following the closing of the initial public
offering, there will be outstanding: (1) 173,913,000 shares of Class A common
stock; (2) options to purchase approximately 50,000,000 shares of Class A
common stock; (3) 18,256,000 shares of Class B common stock, all of which will
be held of record by Verizon as of that date; (4) no shares of Class C common
stock; and (5) no shares of preferred stock.

Long-Term Stock Incentive Plan

   Genuity's employees have historically been among those granted options to
purchase common stock of GTE. The Long-Term Stock Incentive Plan was adopted by
the board of directors. The Long-Term Stock Incentive Plan provides for the
following awards based on the Class A common stock: stock options, stock
appreciation rights, performance bonuses and other stock-based awards. Awards
may be granted to employees

               NOTES TO COMBINED FINANCIAL STATEMENTS--Continued

             (Including Data Applicable to Unaudited Periods)

of Genuity or any entity in which it owns at least a 10% interest. The Long-
Term Stock Incentive Plan will be administered by the executive compensation
committee of the Genuity board of directors. The administrator has the
authority to determine eligibility, grant awards and make all other
determinations under the plan.

   Stock options granted under the Long-Term Stock Incentive Plan may have a
term of up to 10 years and may be either incentive stock options, as defined in
the Internal Revenue Code, or nonqualified stock options. Stock options granted
may not be assigned other than by will or by applicable laws descent and
distribution. The period or periods during which an award will be exercisable
or remain outstanding, including any periods following termination of service,
the manner of exercise and other details of awards will be determined by the
administrator consistent with the Long-Term Stock Incentive Plan.

   Genuity has reserved       shares of Class A common stock for issuance under
the 2000 Long-Term Stock Incentive Plan, subject to adjustment for stock splits
and similar events. Concurrently with the initial public offering, the Company
expects to issue options to purchase        shares of Genuity's Class A common
stock at an exercise price equal to the initial public offering price. The 2000
Long-Term Stock Incentive Plan will terminate at the annual shareholders'
meeting in 2010, unless sooner terminated in accordance with the terms of the
plan.

Outside Directors' Compensation Plan

   Pursuant to the Outside Directors' Compensation Plan, non-employee directors
who have agreed to serve on Genuity's board of directors at the time of the
proposed initial public offering will receive, effective upon the completion of
this offering, a $30,000 annual cash fee and options to purchase 30,000 shares
of Class A common stock at an exercise price equal to the initial public
offering price. In addition, non-employee directors who agree after the initial
public offering to serve on the board of directors will receive, effective upon
election to the board of directors, a $30,000 annual cash fee and options to
purchase 30,000 shares of Class A common stock at an exercise price equal to
the fair market value at the time of the grant. Options issued to the directors
will vest in three equal installments. The first installment will immediately
vest on the date of grant, but will not become exercisable until the day
immediately before the first annual meeting of the stockholders. The second
installment will vest and become immediately exercisable on the day immediately
before the second annual meeting of the stockholders. The third installment
will vest and become immediately exercisable on the day immediately before the
third annual meeting of the stockholders. If a director is not elected to the
board of directors at an annual meeting of the stockholders all unvested
options will expire.

15. Pro Forma (unaudited)

   On      , 2000 GTE made a capital contribution of $    to Genuity.

   The pro forma effect of GTE's capital contribution, estimated to be $178
million as of March 31, 2000 and the sale of Class A common stock, assuming the

                  enterprises seeking to connect to networks with large numbers
                  of users. At Genuity, we capitalize on our large base of on-

ITEM 14. Indemnification of Directors and Officers.

   Section 145 of the Delaware General Corporation Law authorizes a court to
award, or the board of directors of a corporation to grant, indemnity to
directors and officers in terms sufficiently broad to permit indemnification
under some circumstances for liabilities, including reimbursement for expenses
incurred, arising under the Securities Act of 1933.

   As permitted by the Delaware General Corporation Law, the certificate of
incorporation of the Registrant provides that its directors shall not be liable
to the Registrant or its stockholders for monetary damages for breach of
fiduciary duty as a director, except to the extent that the exculpation from
liabilities is not permitted under the Delaware General Corporation Law as in
effect at the time the liability is determined. As permitted by the Delaware
General Corporation Law, the certificate of incorporation of the Registrant
also provides that the Registrant shall indemnify its directors to the full
extent permitted by the laws of the State of Delaware.

   The Registrant is in the process of obtaining policies of insurance under
which coverage will be provided (a) to its directors and officers against loss
arising from claims made by reason of breach of fiduciary duty or other
wrongful acts, including claims relating to public securities matters and (b)
to the Registrant with respect to payments which may be made by the Registrant
to these officers and directors pursuant to the above indemnification provision
or otherwise as a matter of law.

   The Underwriting Agreement provides for the indemnification of officers and
directors of the Registrant by the Underwriters against some types of
liability.

ITEM 15. Recent Sales of Unregistered Securities.

   In the three fiscal years prior to the effective date of this Registration
Statement, we have issued and sold the following unregistered securities:

   On September 12, 1997, Genuity issued and sold 500 shares of its common
stock, par value $1.00 per share, to GTE Corporation for an aggregate price of
$500.

   On       , 2000, Genuity issued 18,256,000 shares of its Class B common
stock, par value $0.01 per share to GTE Corporation in exchange for 500 shares
of its common stock, par value $1.00 per share, held by GTE Corporation.

                                      II-1
<PAGE>

   The sales and issuances of securities listed above, other the sales and
issuances in Item   , were deemed to be exempt from registration under Section
4(2) of the Securities Act or Regulation D thereunder as transactions not
involving a public offering. The sales and issuances of securities listed above
in Item    were deemed to be exempt from registration under the Securities Act
by virtue of Rule 701 promulgated under Section 3(b) of the Securities Act of
1933 as transactions pursuant to compensation benefit plans and contracts
relating to compensation. All of the foregoing securities are deemed restricted
securities for purposes of the Securities Act.

*To Be Filed By Amendment.

+Previously Filed.

(1)  There are portions of these agreements that have been omitted pursuant to
     a request for confidential treatment filed separately with the Securities
     and Exchange Commission.

(2)  These agreements are being filed in the form in which they will be
     executed immediately upon the closing of the merger of Bell Atlantic
     Corporation and GTE Corporation.


   Other financial statement schedules are omitted because the information
called for is not required or is shown either in the financial statements or
the notes thereto.

ITEM 17. Undertakings.

    (a) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under "Item 14--Indemnification
of Directors and Officers" above, or otherwise, the Registrant has been advised
that in the opinion of the Securities and Exchange Commission this
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against these liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by the
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether the indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of the issue.

    (b) The undersigned Registrant hereby undertakes that:

        (1) For purposes of determining any liability under the Securities
    Act, the information omitted from the form of prospectus filed as part
    of this Registration Statement in reliance upon Rule 430A and contained
    in a form of prospectus filed by the Registrant pursuant to Rule
    424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to
    be part of this Registration Statement as of the time it was declared
    effective.

        (2) For the purposes of determining any liability under the
    Securities Act, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating
    to the securities offered therein, and the offering of these securities
    at that time shall be deemed to be the initial bona fide offering
    thereof.

    (c) The undersigned Registrant hereby undertakes to provide to the
underwriters at the closing specified in the underwriting agreement,
certificates in the denominations and registered in the names required by the
underwriters to permit prompt delivery to each purchaser.

<PAGE>

     and administration with respect to the Plan, Awards, and Award Agreements
     shall be determined by the Committee in its sole and absolute discretion,
     and its determinations shall be final and binding upon all parties.

(b)  The Committee may delegate its authority under subsection (a), above, to
     persons other than its members to the extent it deems such action
     advisable.  Any person to whom the Committee has delegated authority under
     subsection (a), above, may receive Awards only if the Awards are granted
     directly by the Committee without delegation.

(c)  The Committee may, in its sole discretion, promulgate general regulations
     and guidelines governing the administration of the Plan and the Awards
     granted hereunder. The Committee also may establish regulations governing
     the deferred payment of Awards and may determine that deferred payments
     shall accrue interest at a rate or rates determined by the Committee and/or
     that deferred payments shall be deemed to be invested in Share equivalents
     or other hypothetical investments.

(d)  The Committee may not at any time adjust the purchase price, Grant Price,
     or Market Price specified by Section 3 hereof (except for adjustments
     pursuant to Section 13 hereof).

6.   TYPES OF AWARDS

     The types of Awards described in subsections (a) through (d), below, may be
     granted or payable under the Plan, singly or in combination or in tandem
     with other Awards (or with awards under other plans of the Company or a
     Related Entity), as the Committee may determine. All Awards shall be in a
     form determined by the Committee. No Award shall be inconsistent with the
     terms of the Plan or fail to satisfy the requirements of applicable law.

     The Committee may, from time to time, grant dividend equivalents in respect
     of Awards.

(a)  Stock Options
     -------------

     A stock option represents the right to purchase a specified number of
     Shares, at a fixed Grant Price, during a specified term as the Committee
     may determine. The term of a stock option shall not exceed ten years from
     the date as of which the Grant Price is determined.

     The Grant Price shall be payable, at the discretion of the Committee, by
     the payment of cash, the delivery of Shares, and/or any other means that


- --------------------------------------------------------------------------------
Genuity Inc. 2000 Long-Term Stock Incentive Plan                          Page 3
<PAGE>

     the Committee determines to be consistent with the Plan's purposes and
     applicable law.

     The stock options that may be granted under the Plan include (but are not
     limited to) incentive stock options that comply with the requirements of
     Section 422(b) of the Code. Incentive stock options may not be granted
     under the Plan after February 1, 2010. Incentive stock options may be
     granted only to Employees who are employed by the Company or by a
     subsidiary corporation (within the meaning of Section 424(f) of the Code),
     including a subsidiary corporation that becomes such after the adoption of
     the Plan.

     The Committee also may grant a right to purchase additional Shares to a
     Participant contingent upon the surrender of Shares owned by the
     Participant in payment of the Grant Price of a stock option granted under
     the Plan or upon the surrender of Shares by the Participant in payment of
     withholding tax liability with respect to such a stock option.

     The Grant Price of the initial stock options granted to Participants who
     were employees of the Company on or before the effective date of the
     Company's initial public offering, shall be the initial public offering
     price per Share. All other stock options granted under the Plan shall be
     exercisable at the Grant Price.

(b)  Stock Appreciation Rights
     -------------------------

     A stock appreciation right represents the right, denominated in Shares, to
     receive, upon surrender of the right (or of both the right and a related
     option in the case of a tandem right), in whole or in part, but without
     payment, an amount (payable in accordance with Section 9 hereof) that does
     not exceed the excess of the Market Price over the Grant Price for the
     number of Shares for which the stock appreciation right is exercised. The
     term of a stock appreciation right shall not exceed ten years from the date
     as of which the Grant Price is determined.

(c)  Performance Bonuses
     -------------------

     The Committee may, from time to time, grant Performance Bonuses to
     Participants in accordance with such terms and conditions that the
     Committee in its sole discretion may establish. Any such Performance
     Bonuses shall be payable in the form of Shares only (except for cash in
     lieu of fractional shares).

<PAGE>

(d)  Other Stock-Based Awards
     ------------------------

     The Committee may, from time to time, grant Awards (other than the Awards
     described above) under the Plan that consist of or are denominated in or
     payable in, valued in whole or in part by reference to, or otherwise based
     on or related to, Shares. These Awards may include Shares and/or
     hypothetical Shares.

     The Committee may subject these Awards to restrictions on transfer and/or
     other restrictions on incidents of ownership as the Committee may
     determine.

     The Committee may grant Awards under this Section 6(d) that do not require
     the payment of additional consideration by the Participant (other than
     services previously rendered or, as may be permitted by applicable law,
     services to be rendered), either on the date of grant or the date any
     restriction(s) thereon are removed.

     The term of an Award that grants a Participant the right to purchase Shares
     shall not exceed ten years from the date as of which the purchase price is
     determined.

7.   LIMITATIONS ON AWARDS

     (a)  No Participant shall be granted options to purchase more than two
          million Shares in one calendar year.

     (b)  Except as provided in subsection (c), below, a Participant shall
          receive only one Award grant during the period beginning on the
          effective date of the Plan and ending four years after the effective
          date of the Plan.

     (c)  A Participant may receive a grant of an Award under the Plan at any
          time to the extent that such grant is consistent with a promotion or
          other significant increase in responsibility or, in the discretion of
          the Committee, necessary to ensure that the Awards granted to such
          Participant are appropriate in comparison to the Awards granted to
          other Participants.

     (d)  No Award shall be assignable or transferable other than by will or by
          the laws of descent and distribution. During the Participant's
          lifetime, an Award may be exercised only by the Participant or by the
          Participant's guardian or legal representative.

8.   AWARD AGREEMENTS

     An Award may be evidenced by an Award Agreement, the terms of which have
     been approved by the Committee, setting forth the terms and conditions
     applicable to the Award, including

     (a)  terms and conditions governing the extent (if any) to which the Award
          may vest, become exercised, be exercised or paid, or be canceled or
          forfeited,

     (b)  terms and conditions governing the disposition of the Award in the
          event of disability, death, or other termination of a Participant's
          employment,

     (c)  a provision that a Participant shall have no rights as a shareholder
          with respect to any Shares covered by an Award until the date on which
          the Participant or his nominee becomes the holder of record of such
          Shares, and

     (d)  terms and conditions governing tax withholding.

9.   PAYMENT OF AWARDS

     (a)  All payments of Awards shall be made on a date prescribed by the
          Committee, unless the Participant has elected to defer payment in
          accordance with the rules and regulations established by the
          Committee.

     (b)  At the discretion of the Committee, a Participant may be offered an
          election to substitute an Award for another Award or Awards of the
          same or different type.

     (c)  No fractional Shares shall be issued in connection with Awards under
          the Plan. The Committee shall determine whether cash, other
          securities, or other property shall be paid or transferred in lieu of
          fractional Shares, or whether fractional Shares or any rights thereto
          shall be canceled, terminated, or otherwise eliminated.

     (d)  Except as provided in subsection (c), above, payments of Awards shall
          be wholly in Shares. The Committee, in its sole discretion, shall
          determine whether the Shares shall be subject to restrictions on
          transfer and/or provisions regarding forfeiture of said Shares.

10.  REVOCATION OR AMENDMENT OF AWARDS

     (a)  Subject to any early termination restrictions imposed by the Committee
          in an Award Agreement and except as provided in subsection (b), below,
          the Committee may not, without the written consent of the Participant,
          revoke

          an Award Agreement, and may not without such written consent make or
          change any determination or change any term, condition, or provision
          affecting an Award if the determination or change would adversely
          affect the Award or a Participant's rights thereto.

     (b)  The Committee may at any time and in any manner modify the terms of an
          Award that relate to the early termination of the option or Award
          period after the Participant's termination of employment; provided
          that such modification shall not apply to an Award to the extent that
          it has been previously exercised.

11.  LIMITATION ON NUMBER OF SHARES

     (a)  The aggregate number of Shares that may be subject to all Awards shall
          not exceed:

          (1)  Five percent of the outstanding Shares at the time of the initial

     Plan as it shall deem advisable, subject to any requirement for shareholder

Genuity Inc. 2000 Long-Term Stock Incentive Plan                          Page 7
<PAGE>

     previously granted Awards shall remain in effect and shall continue to be
     governed by the terms of the Plan, the Awards, and any applicable Award
     Agreements. This Section applies regardless of whether the termination of
     the Plan occurs pursuant to Section 2 hereof or pursuant to this Section
     12.

13.  ADJUSTMENT PROVISIONS

     If the Committee determines that any dividend or other distribution
     (whether in the form of cash, Shares, other securities, or other property),
     extraordinary cash dividend, recapitalization, stock split, reverse stock
     split, reorganization, merger, consolidation, split-up, spin-off,
     combination, repurchase, or exchange of Shares or other securities, the
     issuance of warrants or other rights to purchase Shares or other
     securities, or other similar corporate transaction or event affects the
     Shares with respect to which Awards have been or may be issued under the
     Plan and that an adjustment is appropriate in order to prevent dilution or
     enlargement of the benefits or potential benefits intended to be made
     available under the Plan, then the Committee shall, in a manner that the
     Committee deems appropriate to prevent such dilution or enlargement, adjust
     any or all of

     (a)  the number and type of securities that thereafter may be issued under
          the Plan,

     (b)  the number and type of securities subject to outstanding Awards, and

     (c)  the Grant Price, purchase price, or Market Price with respect to any
          Award, or, if deemed appropriate, make provision for a cash payment to
          the holder of an outstanding Award.

     However, no adjustment shall be authorized with respect to incentive stock
     options to the extent that the adjustment would cause the options to
     violate Section 422(b) of the Code or any successor provision.  In
     addition, the number of securities subject to any Award denominated in
     Shares shall always be a whole number.

     In the event of an acquisition by the Company by means of a merger,
     consolidation, acquisition of property or stock, reorganization or
     otherwise, the Committee shall be authorized to cause the Company to issue
     or to assume stock options or stock appreciation rights, whether or not in
     a transaction to which Section 424(a) of the Code applies, by means of
     substitution of new options or rights for previously issued options or
     rights or an assumption of previously issued options or rights, but only if
     and to the extent that the substitution or assumption is consistent with
     the other provisions of the Plan and with any applicable law.

<PAGE>

     Subject to any required action by the Company's shareholders, if the
     Company is a party to any merger or consolidation, a Participant holding an
     outstanding Award valued directly or indirectly by Shares shall be entitled
     to receive, upon the exercise of the Award, the same per Share
     consideration on the same terms that a holder of the same number of Shares
     that are subject to the Award would be entitled to receive pursuant to the
     merger or consolidation.

14.  NO REQUIRED SEGREGATION OF ASSETS

     Neither the Company nor any Related Entity shall be required to segregate
     any assets that may at any time be represented by Awards pursuant to the
     Plan.

15.  COSTS

     The Committee may require a Participant or beneficiary to bear all or part
     of the cost of exercising an Award or issuing Shares under the Plan.

16.  RIGHT OF DISCHARGE RESERVED

     Neither the Plan nor any Award or Award Agreement shall guarantee any
     Employee continued employment with the Company or a Related Entity or
     guarantee the grant of future Awards.  Either the Company or the Employee
     may terminate the employment relationship at any time and for any reason.

17.  NATURE OF PAYMENTS

     All Awards made pursuant to the Plan are in consideration of services for
     the Company or the Related Entities. Any gain realized pursuant to Awards
     under the Plan constitutes a special incentive payment to the Participant
     and shall not be taken into account as compensation for purposes of any of
     the employee benefit plans of the Company or any Related Entity except as
     may be determined by the Board or by the board of directors of the
     applicable Related Entity.

18.  SEVERABILITY

     If any provision of the Plan shall be held unlawful or otherwise invalid or
     unenforceable in whole or in part, the unlawfulness, invalidity, or
     unenforceability shall not affect any other provision of the Plan or part
     thereof, each of which shall remain in full force and effect.

19.  GOVERNING LAW

     To the extent not preempted by federal law, the provisions of the Plan will
     be construed and enforced in accordance with the laws of the Commonwealth
     of Massachusetts, excluding any conflicts or choice of law rule or
     principle that might otherwise refer construction or interpretation of this
     provision to the substantive law of another jurisdiction, except that
     issues regarding the rights attendant to stock ownership shall be governed
     by the laws of the State of Delaware (excluding its conflicts or choice of
     law rules or principles) and construed accordingly.

6.   OPTIONS

     (a)  At the beginning of each Participant's initial term as a Director,
          the Participant shall receive an option to purchase 30,000 Shares. At
          the beginning of any subsequent three-year term to which each
          Participant may be elected and begin to serve as a Director, the
          Participant shall receive an additional option to purchase 30,000
          Shares; provided, that a participant whose initial term was less than
          three years shall not receive an additional 30,000 options upon his or
          her first election to a full three-year term. The Committee shall have
          discretion to award a pro rated option to any Director who begins to
          serve a term as a Director that is expected to be less than three
          years in duration.

     (b)  The Grant Price shall be payable, at the discretion of the Committee,
          by the payment of cash, the delivery of Shares, and/or any other means
          that the Committee determines to be consistent with the Plan's
          purposes and applicable law.

     (c)  The Committee also may grant an Option to purchase additional Shares
          to a Participant contingent upon the surrender of Shares owned by the
          Participant in payment of the Grant Price under an Option or upon the
          surrender of Shares by the Participant in payment of withholding tax
          liability with respect to an Option.

     (d)  The initial Option granted to the eligible members of the Company's
          initial Board shall be exercisable at the initial public offering
          price per Share. Any other Option granted under the Plan shall be
          exercisable at the Grant Price.

7.   LIMITATIONS ON OPTIONS

     (a)  The only Options that may be granted under the Plan are those set
          forth in Section 6 hereof.

     (b)  No Option awarded under the Plan shall be assignable or transferable
          other than by will or by the laws of descent and distribution. During

          Participant or by the Participant's guardian or legal representative.

     (c)  No fractional Shares shall be issued in connection with Options under
          the Plan. The Committee shall determine whether cash, other
          securities, or other property shall be paid or transferred in lieu of
          fractional Shares, or whether fractional Shares or any rights thereto
          shall be canceled, terminated, or otherwise eliminated.

     (d)  Except as provided in subsection (c), above, and Section 10 hereof,
          payments of Options shall be wholly in Shares. The Committee, in its
          sole

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

     Genuity Inc. Outside Directors' Compensation Plan                    Page 3
<PAGE>

          discretion, shall determine whether the Shares shall be subject to
          restrictions on transfer and/or forfeiture provisions.

8.   OPTION AGREEMENTS

     An Option may be evidenced by an Option Agreement, the terms of which have
     been approved by the Committee, setting forth the terms and conditions
     applicable to the Option, including

     (a)  terms and conditions governing the extent (if any) to which the Option
          may become vested or exercisable or be exercised or paid,

     (b)  terms and conditions governing the disposition of the Option in the
          event of disability, death or other termination of a Participant's
          status as a Director, and

     (c)  a provision that a Participant shall have no rights as a shareholder
          with respect to any Shares covered by an Option until the date on
          which the Participant or his nominee becomes the holder of record of
          such Shares.

9.   REVOCATION OR AMENDMENT OF OPTIONS

     (a)  Except as provided in subsection (b) and Section 10, below, the
          Committee may not, without the written consent of the Participant,
          revoke an Option Agreement, and may not without such written consent
          make or change any determination or change any term, condition, or
          provision affecting an Option if the determination or change would
          adversely affect the Option or a Participant's rights thereto.

     (b)  The Committee may at any time and in any manner modify the terms of an
          Option that relate to the early termination of the Option after the
          Participant's separation from the Board; provided that such
          modification shall not apply to an Option to the extent that it has
          been previously exercised.

10.  FORFEITURE OF OPTIONS

     (a)  A Participant who does not complete the three-year term as a Director
          for which an Option was granted shall, upon removal or withdrawal from
          the Board, forfeit any then-unvested portion of the Option.

     (b)  Except to the extent a shorter time period is dictated by another
          provision of the Plan or by an Award Agreement, any portion of an
          Option that is not exercised within five years of the Participant's
          separation or withdrawal from the Board shall be forfeited.

11.  AMENDMENT OR TERMINATION OF THE PLAN

     The Board may, from time to time, alter, amend, suspend, or terminate the
     Plan as it shall deem advisable, subject to any requirement for shareholder
     approval imposed by applicable law.  The termination of the Plan shall not
     cause any previously granted Options to terminate.  After the termination
     of the Plan, any previously granted Options shall remain in effect and
     shall continue to be governed by the terms of the Plan, the Options, and
     any applicable Option Agreements. This Section applies regardless of
     whether the termination of the Plan occurs pursuant to Section 2 hereof or
     pursuant to this Section 11.

12.  ADJUSTMENT PROVISIONS

     If the Committee determines that any dividend or other distribution
     (whether in the form of cash, Shares, other securities, or other property),
     extraordinary cash dividend, recapitalization, stock split, reverse stock
     split, reorganization, merger, consolidation, split-up, spin-off,
     combination, repurchase, or exchange of Shares or other securities, the
     issuance of warrants or other rights to purchase Shares or other
     securities, or other similar corporate transaction or event affects the
     Shares with respect to which Options have been or may be issued under the
     Plan and that an adjustment is appropriate in order to prevent dilution or
     enlargement of the benefits or potential benefits intended to be made
     available under the Plan, then the Committee shall, in a manner that the
     Committee deems appropriate to prevent such dilution or enlargement, adjust
     any or all of

     (a)  the number and type of securities that thereafter may be issued under
          the Plan,

     (b)  the number and type of securities subject to outstanding Options, and

     (c)  the Grant Price with respect to any outstanding Option, or, if deemed
          appropriate, make provision for a cash payment to the holder of an
          outstanding Option.

     The number of Shares subject to any Option shall always be a whole number.

     Subject to any required action by the Company's shareholders, if the
     Company is a party to any merger or consolidation, a Participant holding an
     outstanding Option shall be entitled to receive, upon the exercise of the
     Option, the same per Share consideration on the same terms that a holder of
     the same number of Shares that are subject to the Option would be entitled
     to receive pursuant to the merger or consolidation.

     thereof, each of which shall remain in full force and effect.

     To the extent not preempted by federal law, the provisions of the Plan will
     be construed and enforced in accordance with the laws of the State of

                                 IRU AGREEMENT
THIS IRU AGREEMENT (this "Agreement") is made and entered into as of May 2,
1997, by and between QWEST COMMUNICATIONS CORPORATION, a Delaware corporation
("QWEST"), and GTE INTELLIGENT NETWORK SERVICES INCORPORATED, a Delaware
corporation ("GTE").
                                   RECITALS
A. QWEST is planning to construct a continuous fiberoptic communication system,
contiguous from end to end, as described in Exhibit A hereto, and between each
of the city pairs identified in Exhibit A-1 hereto (the fiberoptic communication
system between each such city pair being referred to as a "Segment"), being
referred to herein collectively as the "QWEST System". The route that the QWEST
System shall follow as described in this paragraph is referred to herein as the
"System Route."
B. GTE desires to be granted the right to use certain optical fibers in the
QWEST System.
C. QWEST desires to grant GTE an exclusive, indefeasible right to use certain
fibers and associated property in the QWEST System, all upon the terms and
conditions set forth below. Accordingly, in consideration of the mutual promises
set forth below, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:
                                  ARTICLE I.
                         GRANT OF IRU IN QWEST SYSTEM

1.1     (a)  Effective as of the effective date described in Section 6.1 below,
for each particular Segment delivered by QWEST to GTE hereunder and with respect
to which an Acceptance Date (as defined in Section 4.2 below) has occurred,
QWEST hereby grants to GTE, and GTE hereby purchases from QWEST, (i) an
exclusive, Indefeasible Right of Use (as defined in Section 33.1(f), for the
purposes described herein, in twenty-four (24) "Dark Fibers" (as defined in
Section 33.1(c)), to be specifically identified, in the QWEST System in the
Segments and more specifically described in the maps included in Exhibit A-3
hereto and (ii) an associated and non-exclusive Indefeasible Right of Use, for
the purposes described herein, in the tangible and intangible property needed
for the use of such Dark Fibers as Dark Fibers, including, but not limited to,
the associated conduit, QWEST's rights in all "Underlying Rights" (as defined in
Section 10.1), but in any event excluding any electronic or optronic equipment
(collectively, the "Associated Property"), for the Term (as defined in Section
6.1) respecting such Segment, and all on the terms and subject to the covenants
and conditions set forth herein (collectively, the "IRUs"). The Dark Fibers
subject to the IRUs are referred to collectively as the "GTE Fibers."
 (b)  The parties acknowledge and agree that the specific route of any Segment
that has not been finally designed or engineered, or with respect to which a
right-of-way agreement has not been obtained as of the date hereof is subject to
final determination by QWEST, based on specific engineering, right-of-way,
permitting, authorization and other requirements; provided, however, that (i)
any such Segment route, as finally determined, must include all of the endpoint
and intermediate point cities identified in Exhibit A-4 and all of the junction
points identified in the System Route maps included in Exhibit A; (ii) no
deviation in the route of any Segment as set forth in the maps included in
Exhibit A-3 shall result in a Material Deviation (as defined below) in the
System Route as set forth in Exhibit A, and (iii) once the final route of any
Segment has been so determined, QWEST shall deliver to GTE corresponding
revisions to the relevant maps included in Exhibit A hereto. As used herein, the
term "Material Deviation" shall mean a deviation in the general route

                                                                          Page 2

of a Segment (A) that modifies the System Route architecture in a manner that
breaks a ring, creates a spur or breaks the contiguous nature of Segments; (B)
that modifies the route of the System Route through any city, identified in
Exhibit A-3 as being the location of a GTE POP site, from the detailed route map
shown in Exhibit A-3 for such city in a manner that materially changes the
proximity of such POP site to the System Route right-of-way (provided that, if
any such detailed city map shows that the POP site is in direct proximity to the
System Route right-of-way, any route modification which does not provide such
direct proximity shall be considered a material change in proximity); (C) that
modifies the route of the System Route through any city, as set forth in the
detailed route map for such city set forth in Exhibit A-3, such that the
location of the route at any point would be moved more than 1,200 feet in any
direction, without the prior written approval of GTE (such approval not to be
unreasonably withheld or delayed); or (D) that modifies any parallel route shown
within any city that is the subject of a detailed map included in Exhibit A-3
such that the distance between such parallel routes is less than 1,200 feet
outside metropolitan areas and less than two city blocks within metropolitan
areas.
(c)     If any deviation(s) in the routes of Segments comprising the System
Route cause(s) the aggregate route miles as reflected in Exhibit A estimated for
the System Route to increase by more than ##MATERIAL OMITTED AND SEPARATELY
FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## %) of such estimate such
mileage shall be solely at QWEST's cost and expense and any route mileage in
excess of the applicable ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN
APPLICATION FOR CONFIDENTIAL TREATMENT## %) increase as aforesaid shall not be
included in the route mileage for purposes of determining the IRU Fee as defined
and described in Section 2.1 below.
                                  ARTICLE II.
                            CONSIDERATION FOR GRANT
2.1     In consideration of the grant of the IRUs hereunder by QWEST to GTE, GTE
agrees to pay to QWEST an IRU fee determined based on the QWEST mileage (and
allocated among the Segments based on Segment Rate mileage as set forth in
Exhibit B. (the "IRU Fee").
 The IRU Fee shall be payable with respect to each Segment according to the
payment schedule set forth in Exhibit B.
2.2     QWEST will fax or send by overnight delivery each invoice for payments
to be made by GTE hereunder. GTE shall pay such invoiced amounts, less any
reasonably disputed amounts, for receipt by QWEST within thirty (30) days after
receipt of such invoice by GTE with respect to payments of the IRU Fee and
within thirty (30) days after receipt of such invoice by GTE for any other
amounts owed to QWEST hereunder; provided that GTE shall provide written notice
describing in detail the basis for any disputed amounts; and provided further
that any disputed amounts that are resolved in favor of QWEST shall be due for
payment based on the original invoice date. All payments to be made by GTE
hereunder of the IRU Fee and of any other amounts in excess of $100,000 shall be
made by wire transfer of immediately available funds to the account or accounts
as QWEST shall notify GTE in writing from time to time. Payments of all other
amounts by GTE hereunder may be made by check payable to QWEST. QWEST agrees to
provide GTE from time to time, upon request, with QWEST's estimate of the next
invoice date for a portion of the IRU Fee and the estimated amount of such IRU
Fee payment; provided that failure to provide any such notice shall not in any
way alter or impair GTE's payment obligations hereunder.
2.3     QWEST and GTE acknowledge and agree that with respect to Segment 23,
notwithstanding the fact that Segment 23 has already been constructed and
installed, delivery of Segment 23 shall occur in two installments of twelve (12)
Dark Fibers each as indicated in Exhibit A, and payment of the IRU Fee
established pursuant to Section 2.1 therefor (other than the initial

deferred until each such deferred installment delivery date as set forth in
Exhibit B.
                                 ARTICLE III.
                       CONSTRUCTION OF THE QWEST SYSTEM
3.1     QWEST shall, at QWEST's sole cost and expense, be responsible for and
shall effect the design, engineering, installation, and construction of those
portions of the QWEST System not already constructed as of the date hereof in
accordance with the System Route (as it may be modified pursuant to Section 1.1)
and in conformity with (i) the construction specifications set forth in Exhibit
C, (ii) industry standards and practices, and (iii) applicable Underlying Rights
Requirements (as defined in Section 11.1). Such responsibilities shall include,
without limitation, preparation of construction drawings, bills of materials,
materials specifications and materials requisitions. Except for the existing
fibers on Segments 11A, 11B, 12A, 12B, 12C and 12D (which are Corning SMF-DS)
and any alternative fibers approved pursuant to the following sentence, all
fiber included in the GTE Fibers shall be Corning SMF-LS non-zero dispersion-
shifted or Lucent Technologies True Wave and shall meet or exceed the applicable
fiber specifications set forth in Exhibit E. QWEST may use alternative types of
fiber equivalent to either of the aforementioned fibers; provided that (i) prior
to any such use, QWEST meets with GTE (and GTE hereby agrees to so meet) to,
cooperatively and in good faith, jointly evaluate the use of any such fiber and
(ii) thereafter, GTE approves the use of such fiber, which approval shall not be
unreasonably withheld or delayed. QWEST agrees that, to the extent possible in
light of the fiber already incorporated in Segments that have been constructed,
in whole or in part, prior to the date hereof and the availability and cost of
the fiber of a particular type and manufacture hereafter, fiber utilized with
respect to the loops, rings and regions of the QWEST System shall be of the same
type and manufacture, as depicted in the fiber deployment diagram set forth in
Exhibit E-1 hereto, indicating the type of fiber QWEST currently plans to use in
each such Segment. Any deviation from the planned fiber use set forth in the
diagram must be approved by GTE, which approval shall not be unreasonably
withheld or delayed.
3.2     Subject to extension for delays described in Article XX, QWEST shall
complete at QWEST's sole cost and expense, all construction, installation, and
satisfactory Fiber Acceptance Testing (as defined in Section 4.1) of each of the
Segments, including the provision of such Regeneration Facilities on such
Segment as may be provided pursuant to Section 7.2(a), by the applicable
"Estimated Delivery Date" (as defined in Section 33.1(d)) respecting such
Segment.
3.3     Except as may be provided herein, QWEST shall, at QWEST's sole cost and
expense, procure all materials to be incorporated in and to become a permanent
part of the QWEST System, including, without limitation, the Regeneration
Facilities provided pursuant to Section 7.2(a).
3.4     QWEST shall, at QWEST's sole cost and expense, obtain all Underlying
Rights and other rights, licenses, permits and authorizations as required
pursuant to Article X hereof.
3.5     QWEST shall perform, at QWEST's sole cost and expense, substantially in
accordance with industry standards and practices and as deemed necessary or
appropriate in QWEST's reasonable business judgment, all supervisory and
inspection services relating to the construction of the QWEST System, including,
without limitation, performing construction inspections to assure that all
construction shall be in material compliance with the specifications, drawings,
Underlying Rights, provisions of this Agreement, and applicable governmental
codes. During the course of construction of each Segment, QWEST shall prepare
and provide to GTE construction schedule and progress reports every two weeks.
GTE shall have the right, but not the obligation, to inspect the construction of
each Segment,

                                                                          Page 4

                            CONFIDENTIAL TREATMENT

including the installation, splicing and testing of the GTE Fiber incorporated
therein, during the course and at the time of the relevant design, construction
and installation period. No inspection or failure to inspect by GTE shall impair
or invalidate any rights and remedies of GTE under this Agreement or modify,
amend or otherwise affect any of the representations, warranties, covenants or
agreements of QWEST under this Agreement.
3.6     Upon GTE's written request, QWEST shall make available for inspection by
GTE, at QWEST's offices, copies of all information, documents, agreements,
reports, permits, drawings and specifications generated, obtained or acquired by
QWEST in performing its duties pursuant to this Article III that are material to
grant of the IRUs to GTE, including, without limitation, the Underlying Rights,
subject only to the conditions that (i) the terms of each such document or the
legal restrictions applicable to such information or document permits
disclosure; provided that QWEST will use its best efforts (without requiring the
expenditure of money) to obtain a waiver of any existing confidentiality and/or
non-disclosure restrictions, and to exempt GTE from subsequent confidentiality
and/or non-disclosure restrictions, that would restrict QWEST's ability to make
such documents and/or information available to GTE for inspection; (ii)
notwithstanding the existence or non-existence of such restrictions and/or
waivers, QWEST may, in its sole discretion, redact portions of such documents it
deems proprietary business terms prior to GTE's inspection. No inspection or
failure to inspect by GTE shall impair or invalidate any rights and remedies of
GTE under this Agreement or modify, amend or otherwise affect any of the
representations, warranties, covenants or agreements of QWEST under this
Agreement.
                                  ARTICLE IV.
                     ACCEPTANCE AND TESTING OF GTE FIBERS
4.1     QWEST shall test all GTE Fibers in accordance with the procedures
specified in Exhibit D ("Fiber Acceptance Testing") to verify that the GTE
Fibers are installed and operating in accordance with the specifications
described in Exhibit D. Fiber Acceptance Testing shall progress span by span
along each Segment as cable splicing progresses, so that test results may be
reviewed in a timely manner. QWEST shall provide GTE at least five (5) days
advance notice of the date and time of each Fiber Acceptance Testing such that
GTE shall have the right, but not the obligation, to have a person or persons
present to observe QWEST's Fiber Acceptance Testing. When QWEST has determined
that the results of the Fiber Acceptance Testing with respect to a particular
span show that the GTE Fibers so tested are installed and operating in
conformity with the applicable specifications set forth in Exhibit D, QWEST
shall promptly provide GTE with a copy of such test results.
4.2     When QWEST reasonably determines in good faith that the GTE Fibers with
respect to an entire Segment are installed and operating in conformity with the
applicable specifications set forth in Exhibit D, QWEST shall promptly provide
written notice of same to GTE (a "Completion Notice"). GTE shall, within thirty
(30) days of receipt of the Completion Notice, either reject the Completion
Notice specifying, in good faith, the defect or failure in such Fiber Acceptance
Testing or give QWEST written notice of acceptance of such Fiber Acceptance
Testing (the period from the date of GTE's receipt of the Completion Notice to
the date of QWEST's receipt of GTE's notice of rejection or acceptance being
referred to herein as the "GTE Review Period"). In the event GTE rejects the
Completion Notice, QWEST shall promptly, and not later than seven days, and at
no cost to GTE, commence to remedy the defect or failure. Thereafter QWEST shall
again give GTE a Completion Notice with respect to such GTE Fibers. The
foregoing procedure shall apply again and successively thereafter for a total of
two attempts to remedy the defect or failure. If QWEST fails to adequately
remedy or complete the defect or failure after two attempts, GTE shall have the
right to proceed promptly and in an economically efficient manner to cure such
defects or failures at QWEST's cost and expense, which shall be paid by QWEST to
GTE upon demand, or at the election of GTE, offset from any IRU Fee payable by

                                                                          Page 5

                            CONFIDENTIAL TREATMENT

GTE to QWEST with respect to such Segment or any other Segment. No acceptance
of, or failure by GTE to reject, the Completion Notice shall be deemed to be a
waiver of any rights or remedies of GTE under this Agreement; provided that, any
failure by GTE to timely reject as set forth above shall operate as a
constructive acceptance for purposes of this Agreement. The date when GTE
accepts or is deemed to have accepted a Completion Notice or cures such defects
at QWEST's cost and expense as provided above with respect to a Segment is
herein defined as the "Acceptance Date".
                                  ARTICLE V.
                                 DOCUMENTATION
5.1     Notwithstanding the conditions and limitations set forth in Section 3.6,
QWEST shall provide GTE with a copy of all Underlying Right Requirements (as
defined in Section 11.1) applicable to each Segment promptly following the grant
to QWEST of the Underlying Right pursuant to which such Underlying Right
Requirements are imposed and, in any event, on or before the date of completion
of conduit installation in such Segment (as defined in Exhibit B, paragraph
3(ii)).
5.2     Not later than ninety (90) days after the Acceptance Date for each
Segment, QWEST shall provide GTE with the following documentation:
(a)     As-built drawings for such Segment in accordance with the requirements
described in Exhibit C ("As-Builts").
(b)     Technical specifications of the optical fiber cable and associated
splices and other equipment placed in that Segment.
5.3     As a condition to, and effective upon receipt of, each IRU Fee payment
installment that is due upon QWEST's achievement of a construction,
installation, testing or acceptance milestone as set forth in Exhibit B, QWEST
shall deliver to GTE a lien waiver with respect to liens in favor of QWEST
arising out of QWEST's services in accomplishing such milestone. Promptly
following QWEST's receipt of each such payment, QWEST shall use reasonable
efforts to obtain (and in any event on or before the Acceptance Date with
respect to the relevant Segment shall obtain) from each subcontractor that
provided services in accomplishing such milestone a lien waiver with respect to
liens arising out of such services and, upon receipt, deliver a copy of each
such lien waiver to GTE.
                                  ARTICLE VI.
                                     TERM
6.1     The grant of the IRUs hereunder with respect to each Segment shall
become effective on the first day when both (i) the Acceptance Date with respect
to that Segment has occurred and (ii) QWEST has received payment in full of the
IRU Fee with respect to such Segment in accordance with Exhibit B, and, subject
to the provisions of Article X, such grant shall terminate at the end of the
economically useful life of the GTE Fibers, as reasonably determined by GTE
pursuant to Section 6.2 below. The period of each such grant respecting each
such Segment and IRU is herein defined as the "Term".
6.2 In the event that GTE, at any time, reasonably determines that the GTE
Fibers comprising any Segment have reached the end of their economically useful
life and desires to not retain the IRU in such Segment, GTE shall have the right
to abandon the IRU with respect to such Segment by written notice to QWEST. If,
at any time during or after the last year of the Minimum Period (as defined in
Section 10.2(ii) below), with respect to any Segment, GTE fails to use any of
the GTE Fibers comprising such Segment for any period of thirty (30) consecutive
days (except to the extent that such non-use is as a result of any of the events
described in Article XX or as a result of QWEST System maintenance, restoration,
relocation, or reconfiguration or as a result of the failure of QWEST to observe
and perform the terms of this Agreement), QWEST shall have the right to request
GTE to acknowledge that the GTE Fibers comprising such Segment have reached the
end of their economic life and, accordingly, has abandoned the GTE Fibers
comprising such Segment (which acknowledgment shall not be unreasonably withheld
or delayed). Upon any such notice of

                                                                          Page 6
<PAGE>

                            CONFIDENTIAL TREATMENT

abandonment or acknowledgment, the Term shall expire with respect to such
Segment and all rights to the use of such Segment shall revert to QWEST without
reimbursement of any fees or other payments previously made with respect
thereto, and from and after such time GTE shall have no further rights or
obligations hereunder with respect to such Segment (subject to the provisions of
Article XIX).
6.3     It is understood and agreed as between the parties that the grant of the
IRUs hereunder shall be treated for accounting and federal and all applicable
state and local tax purposes as the sale and purchase of the GTE Fibers and a
corresponding interest in QWEST's rights in the Associated Property subject
thereto, and that on and after the Acceptance Date with respect to each Segment,
GTE shall be treated as the owner of the GTE Fibers and an interest in QWEST's
rights in the Associated Property comprising such Segment for such purposes. The
parties agree to file their respective financial reports, income tax returns,
property tax returns, and other returns and reports for their respective
Impositions (as such term is defined in Section 33.1(e)) on such basis and,
except as otherwise required by law, not to take any positions inconsistent
therewith. QWEST shall retain legal title to the entire QWEST System, including
the GTE Fibers and Associated Property subject to the IRUs hereunder. In the
event the grant is not treated as a sale and purchase for tax purposes, the
parties shall pay any taxes arising by reason of such tax treatment on the same
basis as if it had been treated as a sale and purchase. Each party agrees to
indemnify the other with respect to any late filing penalties, interest or fees
incurred as a result of such party's failure to provide the other with such
information solely in such party's possession or control that may be necessary
in order to timely make any such filing.
6.4     This Agreement shall become effective on the date hereof and shall
terminate on the date when, after completion and delivery of all Segments
required to be delivered hereunder, all the Terms of all such Segments shall
have expired; provided that, those provisions of this Agreement which, by their
express terms, are intended to survive such termination, shall survive.
                                 ARTICLE VII.
                    NETWORK ACCESS; REGENERATION FACILITIES
7.1     (a) QWEST shall provide GTE with access to, and GTE shall have the right
to connect, at GTE's sole cost and expense, its telecommunications system with,
the GTE Fibers at various network access points on the QWEST System right-of-way
in each of the endpoint cities and intermediate point cities along the route of
each Segment and at such additional locations along the QWEST System right-of-
way as may be requested by GTE (each such access point being referred to as a
"Connecting Point"). The specific locations of each such Connecting Point shall
be as mutually reasonably agreed upon by the parties in good faith, subject to
the Underlying Rights Requirements and QWEST obtaining other required permits,
authorizations and approvals (which QWEST agrees to use its best efforts to
obtain). Any such connection will be performed by QWEST, at GTE's sole cost and
expense, in accordance with QWEST's applicable specifications and operating
procedures. GTE shall pay QWEST's Costs for each such connection within thirty
(30) days of the date of GTE's receipt of QWEST's invoice therefor. In order to
schedule a connection of this type, GTE shall request and coordinate such work
not less than ninety (90) days in advance of the date the connection is
requested to be completed. Such work will be restricted to a Planned System Work
Period ("PSWP"), as defined in Section 33.1(i), unless otherwise agreed to in
writing for specific projects. Subject to all applicable Underlying Rights
Requirements, GTE shall also be provided reasonable access by QWEST to any
Connecting Point at all times. GTE shall have no limitations on the types of
electronics or technologies employed to utilize the GTE Fibers, subject to
mutually agreeable safety procedures and so long as such electronics or
technologies do not interfere with the use of or present a risk of damage to any
portion of the QWEST System.

                                                                          Page 7

                            CONFIDENTIAL TREATMENT

(b)     QWEST may route the GTE Fibers through QWEST's separate terminal,
endlink, POP or Regeneration Facilities at its sole discretion so long as such
routing does not have a material adverse effect on the security, the safety or
GTE's use of the GTE Fibers or Associated Property hereunder and QWEST is
responsible for all costs and expenses associated therewith.
7.2     (a) QWEST will provide GTE with regeneration site facilities as
identified on Exhibit F or as mutually agreed by the parties to be located at
approximately sixty (60) mile intervals along the QWEST System right-of-way, in
each case consisting of and providing space of approximately ##MATERIAL OMITTED
AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## square
feet and amenities (except for the operating costs associated therewith
expressly required to be paid by GTE pursuant to Section 8.2), as described in
Exhibit F ("Regeneration Facilities") at the rates set forth below. The parties
acknowledge that (i) the locations of such Regeneration Facilities shall be
coincident with the locations of QWEST's own Regeneration Facilities. In
addition, QWEST shall provide to GTE at GTE's Prorated Cost (as defined below in
this paragraph (a)) POP or terminal facilities of approximately ##MATERIAL
OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT##
square feet along the QWEST System right-of-way at such locations as may be
mutually determined by GTE and QWEST, subject to space and power availability
and Underlying Rights Requirements. GTE's Occupancy of and access to all such
Regeneration Facility Sites (or POP or terminal facilities) shall include
separate, secured, 24-hour-per-day building access. Any Regeneration Facilities
(or POP or terminal facilities) provided by QWEST to GTE shall be at GTE's
Prorated Cost. For purposes of the foregoing two sentences, GTE's Prorated Cost
for Regeneration facilities means $ ##MATERIAL OMITTED AND SEPARATELY FILED

(b)     Except as provided in Section 8.2 or as otherwise agreed upon, in
writing, by the parties, all amounts payable under this Section 7.2 shall be due
upon the date that the subject facility is available for occupancy by GTE and
shall be paid in the manner specified in Section 2.2.
   7.3  Notwithstanding any qualifications or limitations on QWEST's obligations
under this Article or elsewhere in this Agreement, including but not limited to
the qualification that any obligation of QWEST is subject to the Underlying
Rights Requirements, QWEST is obligated to use its best efforts to obtain and
provide any requisite consents, approvals, permits, authorizations and rights as
may be necessary in order for GTE to be able to install necessary equipment
and/or facilities, to have access to and to maintain its equipment and
facilities, to fully utilize the GTE Fibers, Associated Property, and the IRU
granted or to be granted to GTE under the Agreement, and to provide maintenance
on the Qwest System should QWEST not provide the maintenance services set out in
Exhibit H. QWEST agrees that in the event GTE's ability to utilize and maintain
the GTE Fibers as herein described is impeded in a material way as a result of
the Underlying Rights Requirements, QWEST agrees to use all commercially
reasonable efforts to amend the Underlying Rights or secure additional rights in
order to provide GTE with full access to the GTE Fibers.
                                 ARTICLE VIII.
                                  OPERATIONS
8.1     Each party shall have full and complete control and responsibility for
determining any network and service configuration or designs, routing
configurations, regrooming, rearrangement or consolidation of channels or
circuits and all related functions with regard to the use of that party's Dark
Fiber.

                                                                          Page 8

8.2     GTE shall reimburse QWEST for GTE's proportionate share of all
reasonable and necessary operating costs incurred by QWEST in connection with
the Regeneration Facilities (or alternatively requested POP or terminal
facilities) provided pursuant to Section 7.2(a), including its proportionate
share of any monthly lease costs for any such facilities and/or underlying
property that QWEST leases (including, to the extent included in such lease
costs, base rent, maintenance, insurance, security and taxes), maintenance of
such facilities, and all power and utility fees and charges, excluding any lease
costs for underlying rights on the right-of-way. GTE's proportionate share of
such operating costs, including a proportionate share of common area costs,
shall be the ratio that the floor space provided to GTE in any such facility
(including a proportionate share of the common area) bears to (i) in the case of
lease costs, the total space in such facility, and (ii) in the case of all other
costs (including common area costs), the total utilized space in such facility.
QWEST shall submit invoices to GTE on an annual basis for GTE's pro rata share
of such operating costs during the preceding twelve months. GTE's reimbursement
obligations for insurance and taxes pursuant to this Section 8.2 shall in no
event be duplicative of GTE's payment obligations for insurance or taxes,
respectively, as provided in Article XIV and XV hereof, and in no event shall
relieve QWEST of its payment obligations for insurance costs or taxes,
respectively, as provided in Article XIV and XV hereof.
8.3     GTE acknowledges and agrees that, except to the extent expressly
provided pursuant to Section 7.2, QWEST is not supplying nor is QWEST obligated
to supply to GTE any optronics or electronics or optical or electrical equipment
or other facilities, including without limitation, generators, batteries, air
conditioners, fire protection and monitoring and testing equipment, all of which
are the sole responsibility of GTE, nor is QWEST responsible for performing any
work other than as specified in this Agreement.
8.4     Upon not less than one hundred twenty (120) days' written notice from
QWEST to GTE, QWEST may, subject to GTE's prior written approval (which approval
shall not be unreasonably delayed or withheld) substitute for the GTE Fibers on
the QWEST System, or any Segment or Segments comprising a portion of said QWEST
System, an equal number of alternative fibers along the same or an alternative
route; provided that in any such event, such substitution (i) shall be in
accordance with GTE's applicable specifications and operating procedures, (ii)
shall be effected at the sole cost of QWEST, including, without limitation, all
disconnect and reconnect costs, fees and expenses, (iii) shall be constructed
and tested in accordance with the specifications and drawings set forth in
Exhibits C and D and Section 4.2, and incorporate fiber meeting the
specifications set forth in Exhibit E, and (iv) shall not interrupt or adversely
affect the use, operation or performance of GTE's network or business, or change
any Connecting Points or endpoints of any Segment or change the location of any
Regeneration Facilities (or POPs or terminal facilities) used by GTE hereunder
or any other GTE POP, node or switch facilities, all as determined by GTE, in
its sole discretion.
                                  ARTICLE IX.
                  MAINTENANCE AND REPAIR OF THE QWEST SYSTEM
9.1     From and after the Acceptance Date with respect to each Segment, the
maintenance of the QWEST System comprising such Segment shall be provided in
accordance with the maintenance requirements and procedures set forth in Exhibit
H hereto.
                                  ARTICLE X.
                    PERMITS; UNDERLYING RIGHTS; RELOCATION
10.1    QWEST covenants and agrees that it shall obtain, during the course of
construction of, and in any event on or before the completion of conduit
installation with respect to, each Segment of conduit to be delivered hereunder
all Underlying Rights (as defined below) and such other rights, licenses,
permits, authorizations, consents and approvals (including, without limitation,
any necessary local, state, federal or tribal authorizations and environmental
permits) that are necessary in order to permit QWEST to construct,

                                                                          Page 9

                            CONFIDENTIAL TREATMENT

install and maintain the conduit and the GTE Fibers to be encompassed in such
Segment in accordance with the terms and conditions hereof. QWEST further
covenants and agrees that it shall obtain, during the course of construction of
and in any event on or before the Acceptance Date with respect to each Segment
to be delivered hereunder, any and all rights-of way, easements, licenses and
other agreements relating to the grant of rights and interests in and/or access
to the real property underlying the QWEST System (collectively, the "Underlying
Rights") and such other rights, licenses, permits, authorizations, consents and
approvals (including without limitation, any necessary local, state, federal or
tribal authorizations and environmental permits) that are necessary in order to
permit QWEST to grant the IRUs, and otherwise to perform its obligations
hereunder, in accordance with the terms and conditions hereof, and to (and all
of which Underlying Rights shall) permit GTE to use the GTE Fibers and
Associated Property as provided and permitted hereunder and in accordance with
the terms and conditions hereof. QWEST shall use its best efforts to cause the
terms of each such Underlying Right to provide GTE with notice of any default on
the part of QWEST and to permit GTE to cure, on behalf of QWEST, any such
default by QWEST and, thereafter, to continue the use of such Underlying Right
in accordance with QWEST's rights and interests thereunder and, if GTE at any
time cures such default by QWEST, QWEST shall reimburse GTE for any and all
amounts reasonably paid by GTE promptly upon demand.
10.2    QWEST further covenants and agrees that, with respect to each Underlying
Right that is necessary in order to continue and maintain the IRUs granted
hereunder, and to permit GTE to exercise its rights to use the GTE Fibers and
Associated Property, in each case in accordance with the terms and conditions
hereof:
(i)     QWEST shall, for a period of

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##

years from the date hereof (or until the earlier to occur of
(A) the expiration of the economically useful life of the GTE Fibers,
as determined pursuant to Section 6.2, or (B) the expiration or
termination of the term of a particular Underlying Right, so long as
any such termination is not effected as a result of any failure of
QWEST (not caused as a result of GTE's failure to observe and perform
its obligations hereunder) to observe and perform its duties,
obligations and responsibilities under such Underlying Right or under
this Agreement, including under this Article X), observe and perform
each and every of its obligations under each document, agreement or
instrument granting or conveying to QWEST such an Underlying Right if
the failure to observe and perform any such obligation or obligations
would permit the grantor of such Underlying Right to terminate such
Underlying Right prior to its stated expiration date, or would
otherwise materially, adversely impair or affect GTE's ability to use
the GTE Fibers and Associated Property, or exercise its rights with
respect thereto, as provided and permitted hereunder; and

(ii)    QWEST shall either require that the initial stated
term of each such Underlying Right be for a period that does not
expire, in accordance with its ordinary terms, prior to the last day
of the Minimum Period (as hereinafter defined with respect to each
Segment) or, if the initial stated term of any such Underlying Right
expires, in accordance with its ordinary terms, on a date earlier than
the last day of the Minimum Period, QWEST shall at its cost exercise
any renewal rights thereunder, or otherwise acquire such extensions,
additions and/or replacements as may be necessary, in order to cause
the stated term thereof to be continued until a date that is not
earlier than the last day of the Minimum Period.  The "Minimum Period"
shall be, with respect to each Segment, the period from the date on
which construction of such Segment commences until the twenty-fifth


                                                                         Page 10

                            CONFIDENTIAL TREATMENT


anniversary of such date; and

(iii) From and after the last day of the Minimum Period, QWEST at its sole cost
shall use its best efforts (without being required to expend commercially
unreasonably amounts therefor) to obtain such extensions and/or renewals as may
be necessary in order to cause the stated term of each such Underlying Right to
be continued for an additional period or periods of, in the aggregate,

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##

years following the Minimum Period or until the earlier expiration of the
economically useful life of the GTE Fibers, as determined pursuant to Section
6.2; provided that QWEST shall not be required to expend, as consideration for
any such renewal or extension, more than the fair market rate payable at such
time for similar rights and terms except to the extent that GTE agrees at its
option to pay directly or reimburse QWEST for any amounts required to be paid in
excess of such fair market rate to renew or extend such an Underlying Right; and

(iv) Throughout the term of each such Underlying Right, QWEST shall at its
reasonable cost and expense defend and protect QWEST's rights in and interests
under the Underlying Rights and GTE's right to use the GTE Fibers and Associated
Property as provided and permitted hereunder against interfering or infringing
rights, interests or claims of third parties.
10.3 Upon the expiration or termination of any Underlying Right that is
necessary in order to grant, continue or maintain an IRU granted hereunder in
accordance with the terms and conditions hereof, so long as QWEST shall have
fully observed and performed its obligations under this Article X with respect
thereto, the Term of the IRUs hereunder with respect to any Segment or Segments
affected thereby shall automatically expire upon such expiration or termination.
10.4 If, after the Acceptance Date with respect to a Segment, QWEST is required
by a third party with legal authority to so require (including, without
limitation, the grantor of an Underlying Right, but only to the extent that such
relocation is not required as a result of a failure by QWEST to observe and
perform its obligations under such Underlying Right or this Agreement), or if
GTE agrees, to relocate any portion of such Segment including any of the
facilities used or required in providing the IRUs in such Segment hereunder,
QWEST shall proceed with such relocation, including, but not limited to, the
right, in good faith, to reasonably determine the extent of, the timing of, and
methods to be used for such relocation; provided that (i) the route of any such
relocation shall be subject to the good faith agreement of the parties with a
bona fide interest therein, (ii) GTE shall be kept fully informed of all other
determinations made by QWEST in connection with such relocation, and (iii) any
such relocation shall be constructed and tested in accordance with the
specifications and drawings set forth in Exhibits C and D, and incorporate fiber
meeting the specifications set forth in Exhibit E. GTE shall reimburse QWEST for
its proportionate share of the Costs of such relocation of the portion of the
Segment so relocated, reduced by such amount, if any, of the portion of such
Costs as are reimbursed to QWEST by the party requiring such relocation, as
follows: (i) if the affected portion of the Segment includes any conduit other
than the conduit housing the GTE Fibers for which QWEST is responsible for
relocation costs, the total Costs of relocation of the conduits (i.e.,
relocation of the conduits only without regard to whether the conduits contain
fibers) shall be allocated based on the overall number of conduits relocated;
(ii) such Costs allocated to the conduit carrying the GTE Fibers plus the Costs
specifically associated with the

                                                                         Page 11
<PAGE>

                            CONFIDENTIAL TREATMENT

relocation of the fiber (i.e., relocation of the fiber only without regard to
relocation of conduit) shall be further allocated to GTE based on GTE's
proportionate share of (A) all Costs of fiber acquisitions, splicing and
testing, prorated based on the total fiber count in the affected Cable, as so
relocated, and (B) all other Costs associated with the relocation of the conduit
housing the affected Cable, prorated based on the total number of owners
(including QWEST) and holders of IRUs or equivalent interests (including long-
term lessees) (each, an "Interest Holder") in the affected Cable, as so
relocated. GTE shall have the right to review and audit all Costs incurred in
connection with such relocation. QWEST shall deliver to GTE updated As-Builts
with respect to the relocated Segment not later than sixty (60) days following
the completion of such relocation. Any condemnation or taking under the power of
eminent domain of all or any portion of a Segment shall be deemed a relocation
required by a third party with legal authority to so require, and such affected
Segment, or portion thereof, shall be relocated in accordance with this Section
10.4 and any condemnation proceeds received by QWEST shall be applied to such
relocation as provided above.
ARTICLE XI.
USE OF QWEST SYSTEM
11.1 The requirements, restrictions, and/or limitations upon GTE's right to use
the GTE Fibers and Associated Property as provided and permitted under this
Agreement imposed under, and associated safety, operational and other rules and
regulations imposed in connection with, the Underlying Rights are referred to
collectively as the "Underlying Rights Requirements." QWEST represents and
warrants that, it has made available to GTE for its review and inspection a copy
of certain documents, agreements, or instruments pursuant to which QWEST has
been granted an Underlying Right as of the date hereof (the "Existing Underlying
Rights"), and certain associated safety, operational and other rules and
regulations imposed in connection with the exercise of its rights thereunder
(all of which are identified on Exhibit I hereto). GTE hereby accepts the
Existing Underlying Rights and the Underlying Rights Requirements associated
therewith. QWEST represents that it is not in default under any of the Existing
Underlying Rights that would permit the grantor of such Underlying Right to
terminate such Underlying Right prior to its stated expiration date, or would
otherwise materially, adversely impair or affect GTE's ability to use the GTE
Fibers and Associated Property, or exercise its rights with respect thereto, as
provided and permitted hereunder, and, to the best of its knowledge, none of the
grantors are in default under the Existing Underlying Rights. With respect to
each Underlying Right (other than the Existing Underlying Rights) obtained after
the date hereof by QWEST (or an Underlying Right existing on the date hereof
under any document, agreement or instrument delivered after the date hereof) in
carrying out its obligations hereunder from the same type of grantor as a
grantor of any Existing Underlying Right, QWEST represents and warrants that the
terms and conditions thereof, and rules and regulations imposed in connection
therewith, shall not impose materially more onerous limitations and restrictions
on the rights of GTE to use the GTE Fibers and Associated Property as permitted
and provided hereunder than those imposed by such type of grantor under and in
connection with the Existing Underlying Rights and Underlying Rights
Requirements associated therewith. To the extent that any such Underlying Right
documents, agreements or instruments were or hereafter are provided in a
redacted format to protect confidential and proprietary business terms, QWEST
represents and warrants that no language or information so redacted constitutes
an Underlying Rights Requirement nor otherwise imposes material requirements,
restrictions and/or limitations upon GTE's right to use the GTE Fibers and
Associated Property as provided and permitted hereunder. QWEST represents to GTE
that the map heretofore provided to GTE delineating the general location of
rights of way, easements and other rights held by QWEST under the principal
agreements evidencing the Existing Underlying Rights is a true and complete
depiction, in all material respects, with respect to the general

                                                                         Page 12
<PAGE>

                            CONFIDENTIAL TREATMENT

location of such Existing Underlying Rights that relate to the GTE Fibers to be
installed along the QWEST System as contemplated by this Agreement.
11.2 GTE represents, warrants and covenants that it will use the GTE Fibers and
Associated Property in compliance with (i) all applicable government codes,
ordinances, laws, rules, regulations and/or restrictions, and (ii) subject to
QWEST's obligations under Section 11.1, the Underlying Rights Requirements.
11.3 In addition to the other rights provided hereunder, but subject to the
provisions of Article VII, the IRUs granted hereunder shall include the right at
GTE's cost to install additional equipment, or replace existing equipment, in
the facility space provided to GTE pursuant to Article VII, subject to the
Underlying Rights Requirements.
11.4 QWEST agrees and acknowledges that it has no right to use the GTE Fibers
during the Term hereof, and that, from and after the effective date of the grant
of each IRU hereunder, QWEST shall keep the GTE Fibers, the Associated Property
and the IRUs granted hereunder free from (i) any liens of any third party
attributable to QWEST, and (ii) any rights or claims of any third party
attributable to QWEST, as and to the extent required pursuant to Article X
hereof. In addition, QWEST agrees that, from and after the execution of this
Agreement and until the effective date of the grant of each IRU hereunder with
respect to any Segment, it shall obtain from any entity in favor of which QWEST
in its discretion shall have granted a security interest or lien on all or part
of such Segment a written nondisturbance agreement substantially to the effect
that such lienholder acknowledges GTE's rights and interests in and to the GTE
Fibers, the Associated Property and the IRU's hereunder and agrees that the same
shall not be diminished, disturbed, impaired or interfered with by such
lienholder.
11.5 Subject to the provisions of Article XXV and this Article XI, GTE may use
the GTE Fibers, the Associated Property and the IRUs for any lawful
telecommunications purpose. For purposes of this Section 11.5
"telecommunications" shall have the meaning as used and interpreted in 47 U.S.C.
Sec.153(2)(43). GTE agrees and acknowledges that it has no right to use any of
the fibers, other than the GTE Fibers, included in the Cable or otherwise
incorporated in the QWEST System, and that GTE shall keep any and all of the
QWEST System, other than the IRU in the GTE Fibers or in the Associated
Property, free from any liens, rights or claims of any third party attributable
to GTE.
11.6 GTE and QWEST shall promptly notify each other of any matters pertaining
to, or the occurrence (or impending occurrence) of, any event which could give
rise to any damage or impending damage to or loss of the QWEST System that are
known to such party. Without limiting the generality of the foregoing, QWEST
shall promptly forward to GTE a copy of any notice of default received by QWEST
with respect to its obligations under any Underlying Right if such default is
not promptly cured by QWEST.
11.7 GTE shall not use the GTE Fibers or any related facilities or equipment in
a way which physically interferes in any way with or adversely affects the use
of the fibers or cable of any other person using the QWEST System, it being
expressly acknowledged that the QWEST System includes or will include other
participants, including QWEST and other owners and holders of Dark Fiber IRUs
and telecommunication system operations. QWEST shall not use any other fibers in
the QWEST System in a way which physically interferes with or adversely affects
the use of the GTE Fibers, and shall obtain a similar agreement from any person
that acquires the right to use fibers in the QWEST System after the date hereof.
11.8 GTE and QWEST each agree to cooperate with and support the other in
complying with any requirements applicable to their respective rights and
obligations hereunder by any governmental or regulatory agency or authority.
11.9 QWEST agrees, so long as any such action would not violate the terms of any
Underlying Right, upon request of GTE, to execute,

                                                                         Page 13
<PAGE>

                            CONFIDENTIAL TREATMENT

file and/or record such documents or instruments as GTE shall deem reasonably
necessary or appropriate to evidence or safeguard the IRUs granted to GTE
hereunder. GTE agrees to reimburse QWEST for all reasonable costs and out-of-
pocket expenses (including, without limitation, reasonable fees and expenses of
legal counsel) incurred by QWEST in fulfilling its obligations under this
Section 11.9.
                                 ARTICLE XII.
                                INDEMNIFICATION
12.1 Subject to the provisions of Articles XIII and XVIII, QWEST hereby releases
and agrees to indemnify, defend, protect and hold harmless GTE and its
employees, officers and directors, from and against, and assumes liability for:
(a) Any injury, loss or damage to any person (including GTE), tangible property
or facilities of any person or entity (including reasonable attorneys' fees and
costs) to the extent arising out of or resulting from the acts or omissions,
negligent or otherwise, of QWEST, its officers, employees, servants, affiliates,
agents, contractors, licensees, invitees or vendors arising out of or in
connection with a default (other than a default caused by a failure of GTE to
perform or comply with its obligations hereunder) by QWEST in the performance of
its obligations or breach of its representations under this Agreement
(including, without limitation, any default by QWEST in the performance of its
obligations under Article X with respect to the Underlying Rights and under
Article XI with respect to its use of the QWEST System); and
(b) Any claims, liabilities or damages, including reasonable attorneys' fees and
costs, arising out of any violation by QWEST of any regulation, rule, statute or
court order of any local, state or federal governmental agency, court or body in
connection with the performance of its obligations under this Agreement.
12.2 Subject to the provisions of Articles XIII and XVIII, GTE hereby releases
and agrees to indemnify, defend, protect and hold harmless QWEST, and its
employees, officers and directors, from and against, and assumes liability for:
(a) Any injury, loss or damage to any person (including QWEST), tangible
property or facilities of any person or entity (including reasonable attorneys'
fees and costs) to the extent arising out of or resulting from the acts or
omissions, negligent or otherwise, of GTE, its officers, employees, servants,
affiliates, agents, contractors, licensees, invitees or vendors arising out of
or in connection with a default (other than a default caused by a failure of
QWEST to perform or comply with its obligations hereunder) by GTE in the
performance of its obligations or breach of its representations under this
Agreement (including, without limitation, any default by GTE in the performance
of its obligations under Article XI with respect to its use of the QWEST
System); and
(b) Any claims, liabilities or damages, including reasonable attorneys' fees and
costs, arising out of any violation by GTE of any regulation, rule, statute or
court order of any local, state or federal governmental agency, court or body in
connection with its use of the IRUs and/or the GTE Fibers and Associated
Property hereunder.
12.3 The parties agree to promptly provide each other with notice of any
lawsuit, judicial, administrative or other dispute resolution action or
proceeding, or claim of which it becomes aware and which it believes may result
in an indemnification obligation hereunder (each, an "Action"); provided that
the failure to provide any such notice shall not affect the indemnifying party's
indemnification obligation unless the indemnifying party is actually prejudiced
by the failure to receive such notice. After receipt of any such notice, if the
indemnifying party shall acknowledge in writing to the indemnified party that
the indemnifying party shall be obligated under the terms of this indemnity
hereunder in connection with such Action, then the indemnifying party shall be
entitled, if it so elects (i) to take control of the defense and investigation
of such Action, (ii) to employ and engage attorneys of its own choice to handle
and defend the same, at the indemnifying party's cost, risk and expense unless
the named parties to such action or proceeding include

                                                                         Page 14
<PAGE>

                            CONFIDENTIAL TREATMENT

both the indemnifying party and the indemnified party and the indemnified party
has been advised in writing by counsel that there may be one or more legal
defenses available to such indemnified party that are different from or
additional to those available to the indemnifying party, in which case the
indemnified party shall also have the right to employ its own counsel in any
such case with the reasonable fees and expenses of such counsel being borne by
the indemnifying party, and (iii) to compromise or settle such Action, which
compromise or settlement shall be made only with the written consent of the
indemnified party, such consent not to be unreasonably withheld. Notwithstanding
anything in this Section 12.3 to the contrary, (i) if there is a reasonable
probability that an indemnifiable claim may materially adversely affect the
indemnified party, other than as a result of money damages or other money
payments, the indemnified party shall have the right to participate in such
defense, compromise or settlement and the indemnifying party shall not, without
the indemnified party's written consent (which consent shall not be unreasonably
withheld), settle or compromise any indemnifiable claim or consent to entry of
any judgment in respect thereof unless such settlement, compromise or consent
includes as an unconditional term thereof the giving by the claimant or the
plaintiff to the indemnified party a release from all liability in respect of
such indemnifiable claim.
12.4 The parties hereby expressly recognize and agree that each party's said
obligation to indemnify, defend, protect and save the other harmless is not a
material obligation to the continuing performance of the parties' other
obligations, if any, hereunder. In the event that a party shall fail for any
reason to so indemnify, defend, protect and save the other harmless, the injured
party hereby expressly recognizes that its sole remedy in such event shall be
the right to bring legal proceedings against the other party for its damages as
a result of the other party's said failure to indemnify, defend, protect and
save harmless. The obligations of the parties under this Article XII shall
survive the expiration or termination of this Agreement.
12.5 Nothing contained herein shall operate as a limitation on the right of
either party hereto to bring an action for damages against any third party,
including indirect, special or consequential damages, based on any acts or
omissions of such third party as such acts or omissions may affect the
construction, operation or use of the GTE Fibers or the QWEST System; provided,
however, that each party hereto shall assign such rights or claims, execute such
documents and do whatever else may be reasonably necessary to enable the other
party to pursue any such action against such third party.
                                 ARTICLE XIII.
                            LIMITATION OF LIABILITY
13.1 Notwithstanding any provision of this Agreement to the contrary, except to
the extent caused by its own willful misconduct, neither party shall be liable
to the other party for any special, incidental, indirect, punitive or
consequential damages, whether foreseeable or not, arising out of, or in
connection with such party's failure to perform its respective obligations or
breach of its respective representations hereunder, including, but not limited
to, loss of profits or revenue (whether arising out of transmission
interruptions or problems, any interruption or degradation of service or
otherwise), cost of capital, or claims of customers, in each case whether
occasioned by any construction, reconstruction, relocation, repair or
maintenance performed by, or failed to be performed by, the other party or any
other cause whatsoever, including breach of contract, breach of warranty,
negligence, or strict liability, all claims with respect to which such special,
incidental, indirect, punitive or consequential damages are hereby specifically
waived. Nothing contained herein shall be construed to prohibit or reduce the
payment by QWEST of the amounts described in Section 18.2 and which the parties

                                   INSURANCE
14.1 During the construction period with respect to any Segment, and until the
Acceptance Date with respect thereto, QWEST shall procure and maintain in force
the following insurance coverage from companies lawfully approved to do business
in the state where the construction will be performed:
(a) not less than $5,000,000 combined single-limit liability insurance, on an
occurrence basis, for personal injury and property damage, including, without
limitation, injury or damage arising from the operation of vehicles or equipment
and liability for completed operations;
(b) workers' compensation insurance in amounts required by applicable law and
employers' liability insurance with a limit of at least $1,000,000 per
occurrence;
(c) automobile liability insurance covering death or injury to any person or
persons, or damage to property arising from the operation of vehicles or
equipment, with limits of not less than $2,000,000 per occurrence; and
(d) any other insurance coverages required pursuant to QWEST's right-of-way
agreements with railroads or other third parties. QWEST shall require its
subcontractors who are engaged in connection with the construction of the QWEST
System to maintain insurance in the types and amounts as would be obtained by a
prudent person to provide adequate protection against loss. In all
circumstances, QWEST shall require its subcontractors to carry a minimum of
$1,000,000 in commercial general liability; and
(e) GTE shall be listed as an additional insured on all policies set forth
above, except workers' compensation. QWEST shall provide to GTE a certificate of
insurance evidencing such insurance coverage. Evidence of insurance furnished
shall contain a clause stating GTE "shall be notified in writing at least thirty
(30) days prior to any cancellation of, or any material change or new exclusions
in the policy."
14.2 Following the Acceptance Date with respect to each Segment, and throughout
the remaining term of the IRU with respect to such Segment, each party shall
procure and maintain in force, at its own expense:
(a) not less than $5,000,000 combined single limit liability insurance, on an
occurrence basis, for personal injury and property damage, including, without
limitation, injury or damage arising from the operation of vehicles or equipment
and liability for completed operations;
(b) workers' compensation insurance in amounts required by applicable law and
employers' liability insurance with a limit of at least $1,000,000 per
occurrence;
(c) automobile liability insurance covering death or injury to any person or
persons, or damage to property arising from the operation of vehicles or
equipment, with limits of not less than $2,000,000 per occurrence; and
(d) any other insurance coverages specifically required of such party pursuant
to QWEST's right-of-way agreements with railroads or other third parties.
14.3 Both parties expressly acknowledge that a party shall be deemed to be in
compliance with the provisions of this Article if it maintains an approved self
insurance program providing for a retention of up to $1,000,000. If either party
provides any of the foregoing coverages on a claims-made basis, such policy or
policies shall be for at least a three-year extended reporting or discovery
period. Unless otherwise agreed, GTE's and QWEST's insurance policies shall be
obtained and maintained with companies rated "A" or better by Best's Key Rating
Guide and each party shall provide the other with an insurance certificate
confirming compliance with this requirement for each policy providing such
required coverage.
14.4 In the event either party fails to obtain the required insurance or to
obtain the required certificates from any contractor and a claim is made or
suffered, such party shall indemnify and hold harmless the other party from any
and all claims for which the

                                                                         Page 16

required insurance would have provided coverage. Further, in the event of any
such failure which continues after seven (7) days' written notice thereof by the
other party, such other party may, but shall not be obligated to, obtain such
insurance and will have the right to be reimbursed for the cost of such
insurance by the party failing to obtain such insurance.
14.5 In the event coverage is denied or reimbursement of a properly presented
claim is disputed by the carrier for insurance provided above, the party
carrying such coverage shall make good-faith efforts to pursue such claim with
its carrier.
14.6 GTE and QWEST shall each obtain from the insurance companies providing the
coverages required by this Agreement the permission of such insurers to allow
such party to waive all rights of subrogation and such party does hereby waive
all rights of said insurance companies to subrogation against the other party,
its parent corporation, affiliates, subsidiaries, assignees, officers,
directors, and employees or any other party entitled to indemnity under this
Agreement.
                                  ARTICLE XV.
                TAXES, FEES AND OTHER GOVERNMENTAL IMPOSITIONS
15.1 The parties acknowledge and agree that it is their mutual objective and
intent to (i) minimize, to the extent feasible, the aggregate Impositions (as
defined in Section 33.1(e)) payable with respect to the QWEST System and (ii)
share such Impositions according to their respective interests in the QWEST
System , and that they will cooperate with each other and coordinate their
mutual efforts to achieve such objectives in accordance with the provisions of
this Article XV.
15.2 (a) QWEST shall be responsible for and shall timely pay any and all
Impositions with respect to the construction or operation of the QWEST System
which Impositions are (i) imposed or assessed prior to the Acceptance Date, (ii)
imposed or assessed with respect to events which occurred or property rights or
obligations of QWEST which existed prior to the acceptance date; or (iii)
imposed or assessed (regardless of the time) with respect to the QWEST System in
exchange for the approval of construction in the original agreement which
resulted in the granting of an Underlying Right. Notwithstanding the foregoing
obligations, QWEST shall have the right to challenge any such Impositions so
long as the challenge of such Impositions does not materially, adversely affect
the title, rights or property to be delivered to GTE pursuant hereto.
     (b) Real and/or personal property or ad valorem taxes shall be prorated
between QWEST and GTE based on the period the Property was owned by each
respective party during the fiscal period for which such taxes were imposed by
the taxing jurisdiction (as such fiscal period is reflected on the bill rendered
by such taxing jurisdiction). If the fiscal period is not identified on the tax
bill, proration between QWEST and GTE shall be calculated based on the privilege
period of the taxing jurisdiction. QWEST and GTE shall pay or be reimbursed for
real and/or personal property taxes (including instances in which such property
taxes have been paid before the Acceptance Date) prorated on this basis.
15.3 Except as to Impositions described in paragraphs (ii) and (iii) of Section
15.2, which are clearly for QWEST's account following the Acceptance Date, QWEST
shall timely pay any and all Impositions imposed upon or with respect to the
QWEST System to the extent such Impositions may not feasibly be separately
assessed or imposed upon or against the respective ownership interests of QWEST
and GTE in the QWEST System; provided that, upon receipt of a notice of any such
Imposition, QWEST shall promptly notify GTE of such Imposition and following
payment of such Imposition by QWEST, GTE shall promptly reimburse QWEST for its
proportionate share of such Imposition, which share shall be determined (i) to
the extent possible, based upon the manner and methodology used by the
particular authority imposing such Impositions (e.g., on the cost of the
relative property interests, historic or projected revenue derived therefrom, or
any combination thereof) and, if based upon projected revenue or gross receipts,
then

                                                                         Page 17

based on the relative number of GTE Fibers in the affected portion of the QWEST
System compared to the total number of fibers in the affected portion of the
QWEST System during the relevant tax period which are subject to an indefeasible
right of use or are otherwise in use; or (ii) if the same cannot be so
determined, then based upon GTE's proportionate share of the total fiber count
in the affected portion of the QWEST System. If QWEST's assessed value, for
property tax purposes, is based on its entire operation in any state (i.e.,
central assessment), QWEST and GTE shall work together in good faith to allocate
a proper portion n of said assessment to the QWEST System and GTE's ownership
interest in the QWEST System. If GTE's assessed value, for property tax
purposes, is based on a duplicate assessment of the same property as QWEST,
QWEST and GTE shall work together in good faith to allocate a portion of this
duplicate assessment to each party. QWEST and GTE shall work together in good
faith to aggressively defend against such duplicate assessment in any state
which attempts to impose a duplicate assessment. QWEST shall provide GTE with
reasonable supporting documentation for Impositions for which QWEST seeks
reimbursement. Any reimbursement made under this Section 15.3 shall be in an
amount that, after deductions of all Impositions required to be paid by QWEST in
respect of the receipt or accrual of such reimbursement and after consideration
of any deduction to which QWEST may be entitled with respect to the payment or
accrual of the Impositions which have been reimbursed shall be equal to the
amount otherwise required to be paid by QWEST hereunder. Hereafter, such
additional amount or amounts shall be referred to as the "Gross-up Amount."
QWEST shall, upon request, provide GTE with documentation in support of any
Gross-up Amount so as to ensure that both parties are made whole in a manner
that is consistent with the mutual objectives set forth in section 15.1 of the
Agreement. If such Gross-up Amount exceeds $
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##
, GTE may elect to engage the services of an independent consultant, at GTE's
sole cost and expense, to review QWEST's computation of such Gross-up Amount.
Any independent consultant selected by GTE shall be subject to approval by
QWEST, which such approval shall not be unreasonably withheld, and such
independent consultant shall be subject to confidentiality restrictions as may
be determined in QWEST's sole discretion. Further, if, after review of such
documentation or otherwise, in the event the parties are unable to agree upon
the amount of the Gross-up Amount, such dispute shall be resolved pursuant to
Article XXI of the Agreement.
15.4 Upon notice of the assertion or proposed assertion of any Imposition
described in Section 15.3 (including Impositions that trigger a Gross-up Amount)
QWEST shall promptly and in good faith consult with GTE concerning the
underlying facts and whether to contest or continue to contest such assertion or
proposed assertion. Notwithstanding any provision herein to the contrary, QWEST
shall have the right to contest any Imposition described in Section 15.3, above,
(including Impositions which trigger a Gross-up Amount), provided that such
contest does not materially adversely affect GTE. Such contest may be pursued by
any lawful means including by non-payment of such Imposition provided such non-
payment contest does not materially, adversely affect the title, rights or
property to be delivered to GTE pursuant hereto. The out-of-pocket costs and
expenses (including reasonable attorneys' fees) incurred by QWEST in any such
contest shall be shared by QWEST and GTE in the same proportion as to which the
parties shared in any such Imposition, as it was originally assessed. Any
refunds or credits resulting from a contest brought pursuant to this Section
15.4 shall be divided between QWEST and GTE in the same proportion as to which
such refunded or credited Impositions were borne by QWEST and GTE. In any such
event, QWEST shall provide timely notice of such challenge to GTE. If QWEST
chooses to proceed with such challenge after receipt of a written objection to
the challenge from GTE, QWEST shall conduct such challenge at its own costs and
expense, provided that GTE shall not

                                                                         Page 18

receive the benefit of any refund or credit, if any, obtained as a result of a
successful challenge. Further, where QWEST does not contest an Imposition, GTE
shall have the right, after notice to QWEST, to contest such Imposition as long
as such contest does not materially, adversely affect the title property or
rights of QWEST. The out-of-pocket costs and expenses (including reasonable
attorneys' fees) incurred by GTE in any such contest shall be shared by GTE and
QWEST in the same proportion as to which the parties shared in such Imposition,
as it was originally assessed. Any refunds or credits resulting from a contest
shall be divided between GTE and QWEST in the same proportion as to which such
refunded or credited Imposition was borne by GTE and QWEST. If GTE chooses to
proceed with such contest after receipt of written objection to the challenge
from QWEST, GTE shall conduct such challenge at its own costs and expense,
provided that QWEST shall not receive the benefit of any refund or credit, if
any, obtained as a result of a successful challenge. Provided, however, that
notwithstanding anything to the contrary in this Article XV, QWEST shall have
complete authority over and discretion to control (including the authority to
dismiss or not pursue) any contests relating to Impositions based upon the
computation of QWEST's taxable income under the Federal Internal Revenue Code or
state income or franchise tax laws (hereinafter "Net Income Based Impositions").
GTE shall, however, be consulted on the conduct and status of such contest.
QWEST shall have no obligation to disclose to GTE its income or franchise tax
returns and records except as to the discrete portion of such return or record
that directly relates to the computation and payment of such Net Income Based
Impositions. Provided further, however, that in the event QWEST shall determine
in its own discretion not to pursue a contest of any Net Income Based Imposition
as to which GTE has requested a contest pursuant to the provisions described
above in this Section 15.4, then GTE shall have no obligation to provide any
reimbursement for such amount if GTE shall have obtained and provided to QWEST
an opinion of nationally recognized legal counsel confirming that a meritorious
defense exists to such Net Income Based Imposition.
15.5 Except as to Impositions described in paragraph (iii) of Section 15.2,
following the Acceptance Date QWEST and GTE, respectively, shall be separately
responsible for any and all Impositions (i) expressly or implicitly imposed
upon, based upon, or otherwise measured by the gross receipts, gross income, net
receipts or net income received by or accrued to such party due to its
respective ownership or use of the QWEST System and/or the GTE Fibers, or (ii)
which have been separately assessed or imposed upon the respective ownership
interest of such party in the QWEST System and/or the GTE Fibers. If the GTE
Fibers are the only fibers located in the Cable from the point where the Cable
leaves the QWEST System right-of-way to a GTE POP, GTE shall be solely
responsible for any and all Impositions imposed on or with respect to such
portion of the QWEST System.
15.6 Notwithstanding any provision herein to the contrary, GTE shall have the
right to protest by appropriate proceedings any Imposition described in Section
15.5, above. In such event, GTE shall indemnify and hold QWEST harmless from any
expense, legal action or cost, including reasonable attorneys' fees, resulting
from GTE's exercise of its rights hereunder. In the event of any refund, rebate,
reduction or abatement to GTE of any such Imposition imposed upon and/or paid by
GTE, GTE shall be entitled to receive the entire benefit of such refund, rebate,
reduction or abatement attributable to GTE's use of the QWEST System. In the
event GTE has exhausted all its rights of appeal in protesting any Imposition
and has failed to obtain the relief sought in such proceedings or appeals
("Finally Determined Taxes and Fees"), GTE and QWEST may jointly agree (with the
consent and participation of the other Interest Holders in the affected portion
of the QWEST System) to relocate a portion of the QWEST System so as to bypass
the jurisdiction which had imposed or assessed such Finally Determined Taxes and
Fees with the total Costs thereof to be shared proportionately as follows: (i)
if the affected portion of the QWEST System includes any conduit other than the
conduit in which the

                                                                         Page 19
<PAGE>

                            CONFIDENTIAL TREATMENT

GTE Fibers are located, the total Costs of relocation of the conduits (i.e.,
relocation of the conduits only without regard to whether the conduits contain
fibers) shall be allocated based on the overall number of conduits in the QWEST
System which are relocated; and (ii) such Costs allocated to the conduit
carrying the GTE Fibers plus the Costs specifically associated with the
relocation of the fiber (i.e., relocation of the fiber only without regard to
relocation of conduit) to be further allocated to GTE based upon GTE's
proportionate share of (A) all Costs of fiber acquisitions, splicing and
testing, prorated based on the total fiber count in the Cable, as so relocated;
and (B) all other Costs associated with the relocation of the conduit housing
the affected Cable, prorated based upon the total number of Interest Holders in
the affected Cable, as so relocated. QWEST shall deliver to GTE updated As-
Builts with respect to the relocated QWEST System not later than sixty (60) days
following the completion of such relocation. If GTE and QWEST do not determine
to relocate the affected portion of the QWEST System, GTE shall have the right
to terminate its use of the GTE Fibers in the affected portion of the QWEST
System. Such termination shall be effective on the date specified by GTE in a
notice of termination, which date shall be at least ninety (90) days after the
notice. Upon such termination, the IRU in the affected portion of the QWEST
System shall immediately terminate, and the GTE Fibers in the affected portion
of the QWEST System shall thereupon revert to QWEST without reimbursement of any
of the IRU Fee or other payments previously made with respect thereto.
15.7 Notwithstanding the provisions of Section 15.6, with respect to any
Impositions relating to the QWEST System which are imposed upon both QWEST and
GTE (or both of their respective interests therein), QWEST, at its option and at
its own expense, shall have the right to direct and manage in good faith any
such contest; subject, however, to reasonable and appropriate consultation with
GTE which hereby agrees to reasonably cooperate with QWEST in any such contest.
The right of QWEST to contest any Imposition pursuant to this Section 15.7 shall
be contingent upon reasonable and appropriate assurances that any such contest
will not adversely affect the title, property or rights of GTE hereunder.
15.8 QWEST and GTE agree to cooperate fully in the preparation of any returns or
reports relating to the Impositions. QWEST and GTE further acknowledge and agree
that the provisions of this Article XV are intended to allocate the Impositions
expected to be assessed against or imposed upon the parties with respect to the
QWEST System based upon the procedures and methods of computation by which
Impositions generally have been assessed and imposed to date, and that material
changes in the procedures and methods of computation by which such assessments
are assessed and imposed could significantly alter the fundamental economic
assumptions underlying the transactions hereunder to the parties. Accordingly,
the parties agree that, if in the future the procedures or methods of
computation by which Impositions are assessed or imposed against the parties
change materially from the procedures or methods of computation by which they
are imposed as of the date hereof, the parties will negotiate in good faith an
amendment to the provisions of this Article XV in order to preserve, to the
extent reasonably possible, the economic intent and effect of this Article XV as
of the date hereof.

                                CONFIDENTIALITY
   17.1 QWEST and GTE hereby agree that if either party provides (or, prior to
the execution hereof, has provided) confidential or proprietary information to
the other party ("Proprietary Information"), such Proprietary Information shall
be held in confidence, and the receiving party shall afford such Proprietary
Information the same care and protection as it affords generally to its own
confidential and proprietary information (which in any case shall be not less
than reasonable care) in order to avoid disclosure to or unauthorized use by any
third party. The parties acknowledge and agree that this Agreement, including
all of the terms, conditions and provisions hereof, and all drafts hereof,
constitutes Proprietary Information. In addition, all information disclosed by
either party to the other in connection with or pursuant to this Agreement,
including prior to the date hereof, shall be deemed to be Proprietary
Information. All Proprietary Information, unless otherwise specified in writing,
shall remain the property of the disclosing party, shall be used by the
receiving party only for the intended purpose, and such written Proprietary
Information, including all copies thereof, shall be returned to the disclosing
party or destroyed after the receiving party's need for it has expired or upon
the request of the disclosing party. Proprietary Information shall

                                                                         Page 21

not be reproduced except to the extent necessary to accomplish the purpose and
intent of this Agreement, or as otherwise may be permitted in writing by the
disclosing party.
   17.2 The foregoing provisions of Section 17.1 shall not apply to any
Proprietary Information which (i) becomes publicly available other than through
the recipient; (ii) is required to be disclosed by a governmental or judicial
law, order, rule or regulation; (iii) is independently developed by the
disclosing party; (iv) becomes available to the disclosing party without
restriction from a third party; or (v) becomes relevant to the settlement of any
dispute or enforcement of either party's rights under this Agreement in
accordance with the provisions of this Agreement, in which case appropriate
protective measures shall be taken to preserve the confidentiality of such
Proprietary Information as fully as possible within the confines of such
settlement or enforcement process. If any Proprietary Information is required to
be disclosed pursuant to the foregoing clause (ii), the party required to make
such disclosure shall promptly inform the other party of the requirements of
such disclosure.
   17.3 Notwithstanding Sections 17.1 and 17.2 of this Article, either party may
disclose Proprietary Information to its employees, agents, and legal, financial,
and accounting advisors and providers (including its lenders and other
financiers) to the extent necessary or appropriate in connection with the
negotiation and/or performance of this Agreement or its obtaining of financing,
provided that each such party is notified of the confidential and proprietary
nature of such Proprietary Information and is subject to or agrees to be bound
by similar restrictions on its use and disclosure.
   17.4 Notwithstanding the foregoing sections of this Article 17, the parties
may provide public statements concerning their participation in this Agreement
that do not disclose Proprietary Information of the other party. Any news
release, public announcement, advertising or any form of publicity pertaining to
this Agreement, provision of services pursuant to it, or association of the
parties with respect to the subject of this Agreement shall be subject to prior
written approval of both parties which approval shall not be unreasonably
withheld.
   17.5 The provisions of this Article XVII shall survive expiration or
termination of this Agreement.
                                ARTICLE XVIII.
                                    DEFAULT
   18.1 With respect to all payments required to be made by GTE hereunder,
including, without limitation, payment of the IRU Fee and all other amounts
payable by GTE hereunder, in the event GTE shall fail to make a payment by the
date due and payable hereunder, from and after such date, (i) such unpaid amount
shall bear interest until paid at a rate equal to the rate set forth in Article
XXX and (ii) if such payment is due with respect to a Segment on or prior to the
Acceptance Date of such Segment, the Estimated Delivery Date for such Segment
shall be extended by a number of days equal to the number of days that elapse
from the date such payment is due until paid. In the event any amount or amounts
due and payable hereunder remain unpaid for a period of eighty (80) days after
written notice from QWEST to GTE, and the amount thereof is not in bona fide
dispute, then QWEST may, in its sole and absolute discretion and in addition to
its other rights and remedies hereunder, after ten (10) days prior written
notice to GTE and the failure of GTE to pay such amount within such ten-day
period, terminate any and all of its obligations hereunder with respect to any
Segment or Segments as to which the Acceptance Date has not yet occurred or the
grant of the IRU with respect to which has not yet become effective, and to
apply any and all amounts previously paid by GTE hereunder with respect to such
Segment or Segments toward the payment of any other amounts then or thereafter
payable by GTE hereunder. With respect to all of its other obligations
hereunder, in the event GTE shall fail to perform a non-payment obligation and
such failure shall continue for a period of thirty (30) days after QWEST shall
have given GTE written notice of such failure, GTE shall be in

                                                                         Page 22

default hereunder unless GTE shall have cured such failure or such failure is
otherwise waived in writing by QWEST within such thirty (30) days; provided,
however, that where such failure cannot reasonably be cured within such 30-day
period, if GTE shall proceed promptly to cure the same and prosecute such cure
with due diligence, the time for curing such failure shall be extended for such
period of time as may be necessary to complete such cure; and provided further
that if GTE certifies in good faith to QWEST in writing that a non-payment
failure has been cured, such failure shall be deemed to be cured unless QWEST
otherwise notifies GTE in writing within fifteen (15) days of receipt of such
notice from GTE. GTE shall be in default hereunder (i) automatically upon the
making by GTE of a general assignment for the benefit of its creditors, the
filing by GTE of a voluntary petition in bankruptcy or the filing by GTE of any
petition or answer seeking, consenting to, or acquiescing in reorganization,
arrangement, adjustment, composition, liquidation, dissolution, or similar
relief; (ii) one hundred twenty (120) days after the filing of an involuntary
petition in bankruptcy or other insolvency protection against GTE which is not
dismissed within such one hundred twenty (120) days, or (iii) upon any default
by GTE under the Guaranty, which default is not cured within the relevant cure
period, if any, provided with respect thereto under the Guaranty. Except as
otherwise provided in this Section 18.1, upon any default by GTE, after written
notice thereof from QWEST, QWEST may (i) take such action as it determines, in
its sole discretion, to be necessary to correct the default and, subject to
Section 13.1, recover from GTE its reasonable costs incurred in correcting such
default, and (ii) pursue any legal remedies it may have under applicable law or
principles of equity relating to such default, including specific performance.
Notwithstanding any other provision of this Agreement, QWEST acknowledges and
agrees that QWEST shall have no right to terminate the IRU or any of the rights
and interests of GTE hereunder with respect to any Segment for which the IRU Fee
relating thereto has been fully paid.
   18.2 (a) With respect to its obligation to complete the construction,
installation, and satisfactory Fiber Acceptance Testing of the GTE Fibers
comprising a particular Segment by the Estimated Delivery Date with respect to
such Segment pursuant to Section 3.2, the parties acknowledge and agree that it
is in their mutual best interest to work together in a cooperative effort to
determine whether and to what extent any event or occurrence that is reasonably
likely to cause a delay in the delivery of a Segment hereunder, as a result of
any force majeure event or other occurrence described in Article XX or
otherwise, can be terminated, resolved or avoided, and to cause the
construction, installation and delivery of the Segment to be completed in the
most expeditious and practical manner feasible under the circumstances.
Accordingly, within three (3) months following its discovery of an event or
occurrence that QWEST reasonably believes is likely to cause (i) an extension of
the Estimated Delivery Date of one hundred twenty (120) days or more pursuant to
Article XX or (ii) a Delivery Default (as defined pursuant to Section 18.2(d)
below), QWEST shall give written notice to GTE of such event or occurrence.
Thereupon, each of QWEST and GTE (i) will designate a senior executive officer
with decision-making authority and familiarity with this Agreement and the
relevant issue hereunder, and (ii) may designate one technical representative
and one financial representative, to participate in the following resolution
efforts. Each of such designees shall participate in such meetings, promptly
scheduled at mutually agreed upon times and places, as may be necessary or
appropriate to discuss in good faith the status of construction of the affected
Segment, the reason or reasons for the anticipated Estimated Delivery Date
extension or Delivery Default, various possible and practical means by which the
event(s) or occurrence(s) causing such anticipated Estimated Delivery Date
extension or Delivery Default might be terminated, avoided or resolved,
including, without limitation, possible modifications to the route, selection of
right-of-way, or manner of construction of the affected Segment, and

                                                                         Page 23

(iii) use their best efforts to settle upon and implement a procedure by which
such event(s) or occurrence(s) may be terminated, avoided or resolved and the
construction, installation and delivery of the affected Segment completed in an
expeditious and economically practical and feasible manner under the
circumstances. The parties acknowledge and agree that, because the QWEST System
includes or will include other participants, including owners and holders of
Dark Fiber IRUs and telecommunication system operations, such meetings may, and
likely will, involve designees and representatives of such other participants,
and the resolution of any matters so acted upon will require the cooperative
efforts of, and have to be structured, to the extent feasible, in an effort to
meet the needs of all such participants. The parties hereto further acknowledge
and agree that no failure of the parties hereto to resolve, or to agree upon a
manner in which they might resolve, any issue addressed hereunder shall impair,
adversely affect or invalidate any of their respective rights, claims or
remedies under this Agreement.
   (b) If, notwithstanding the efforts of the parties pursuant to Section
18.2(a): (i) (A) a force majeure event or occurrence described in Article XX
causing an anticipated Estimated Delivery Date extension has not been
terminated, avoided or resolved by the date that is twelve (12) months following
QWEST's discovery of such event or occurrence, and
(B)     there is no "Reasonably Apparent Probability" (either as mutually
determined by QWEST and GTE or, if QWEST and GTE are unable to make such a
mutual determination, as determined by an independent third party mutually
selected by QWEST and GTE and familiar with large-scale fiberoptic system
constructions projects or, if QWEST and GTE are unable to make such a mutual
selection, each of QWEST and GTE shall designate such an independent third
party, the two of which shall designate such an independent third party to make
such determination) that the Acceptance Date with respect to any such affected
Segment will occur within (1) twelve (12) months following the Estimated
Delivery Date (without extension for any delay pursuant to Article XX) with
respect to any Segment designated as a "priority" Segment on Exhibit A-1, or (2)
eighteen (18) months following the Estimated Delivery Date (without extension
for any delay pursuant to Article XX) with respect to any other Segment (such
date with respect to each Segment being referred to as the "Outside Force
Majeure Date"); or
(ii) notwithstanding a determination pursuant to the foregoing clause (i) that
there was a Reasonably Apparent Probability that the Acceptance Date with
respect to the affected Segment would occur by the applicable Outside Force
Majeure Date, nonetheless the event or occurrence described in Article XX
causing such delay is continuing on such applicable Outside Force Majeure Date;
or
(iii) notwithstanding such a determination that there was a Reasonably Apparent
Probability that the Acceptance Date with respect to the affected Segment would
occur by the applicable Outside Force Majeure Date, nonetheless, on the
applicable Outside Force Majeure Date, although the event or occurrence
described in Article XX has been terminated, avoided or resolved and QWEST has
resumed its construction, installation, splicing, and/or testing efforts, QWEST
is unable to demonstrate to GTE's reasonable satisfaction that the Acceptance
Date for such Segment will occur, in all reasonable probability, by the date
that is six (6) months following such Outside Force Majeure Date, then, in any
such event described in foregoing clauses (i), (ii), and (iii), GTE may elect,
in its sole discretion, by written notice to QWEST, to delete such Segment from
the System Route otherwise to be delivered pursuant to this Agreement, and
recover from QWEST (1) the amount of the IRU Fee previously paid by GTE
hereunder with respect to such Segment, plus (2) interest at the prime rate

loans posted by a substantial percentage of the nation's largest banks on such

Upon any such election and payment (or offset), neither party shall have any
further rights or obligations with respect to such Segment hereunder. (c) If,

such event or occurrence; and
(B)     there is no Reasonably Apparent Probability that the Acceptance Date
with respect to any such affected Segment will occur within (x) twelve (12)
months following the Estimated Delivery Date with respect to each Segment
designated as a "Priority" Segment on Exhibit A-1, or (y) eighteen (18) months

QWEST (1) the amount of the IRU Fee previously paid by GTE hereunder with
respect to such Segment, plus (2) interest thereon at the rate of interest
applicable to late payments set forth in Article XXX, plus (3) an amount equal

amount payable to GTE promptly following QWEST's receipt of such election notice
or, at the election of GTE, offset against the unpaid amount of the IRU Fee
payable hereunder with respect to any other Segment or Segments). Upon any such
election and payment (or offset), neither party shall have any further rights or

specific rights and remedies provided pursuant to the foregoing paragraphs (b)

Segments hereunder, QWEST shall be in default under this Agreement if the
Acceptance Date with respect to any Segment has not occurred within one hundred
twenty (120) days after the Estimated Delivery Date (a "Delivery Default"). From
the date of any such Delivery Default, and until the Acceptance Date with
respect to such Segment occurs, the IRU Fee with respect to such Segment, as

Fibers comprising any Segment by the relevant Estimated Delivery Date (it being
expressly acknowledged and agreed that the rights provided to GTE pursuant to
Section 18.2(b) are provided only as an accommodation in the event of lengthy
force majeure delays pursuant to Article XX, and that the events described in
Section 18.2(b) do not constitute defaults hereunder). With respect to all of
QWEST's other obligations hereunder, in the event that QWEST shall fail to
perform an obligation and such failure shall continue for a period of thirty
(30) days after GTE shall have given QWEST written notice of such failure, QWEST
shall be in default hereunder unless QWEST shall have cured such failure or such
failure is otherwise waived in writing by GTE within such thirty (30) days;
provided however, that where such failure cannot reasonably be cured within such
30-day period, if QWEST shall proceed promptly to cure the same and prosecute
such cure with due diligence, the time for curing such failure shall be extended
for such period of time as may be necessary to complete such cure; and provided
further, that if QWEST certifies in good faith to GTE in writing that failure
has been cured, such failure shall be deemed to be cured unless GTE otherwise
notifies QWEST in writing within fifteen (15) days of receipt of such notice
from QWEST. QWEST shall be in default hereunder automatically upon the making by
QWEST of a general assignment for the benefit of its creditors, the filing by
QWEST of a voluntary petition in bankruptcy or the filing by QWEST of any
petition or answer seeking, consenting to, or acquiescing in reorganization,
arrangement, adjustment, composition, liquidation, dissolution, or similar
relief, or (ii) one hundred twenty (120) days after the involuntary filing of a
petition in bankruptcy or other insolvency protection against QWEST which is not
dismissed within such 120-day period. Except as otherwise provided in this
Section 18.2, upon any default by QWEST, after notice thereof from GTE, GTE may
(i) take such action as it determines, in its sole discretion, to be necessary
to correct the default, and, subject to Section 13.1, recover from QWEST its
reasonable costs in correcting such default, and (ii) pursue any legal remedies
it may have under applicable law or principles of equity relating to such
default including specific performance.

19.1    This Agreement automatically shall terminate with respect to a Segment
upon the expiration or termination of the Term of the IRU respecting such
Segment pursuant to Article VI or Section 18.2 hereof.
19.2 Upon the expiration or termination of this Agreement with respect to a
Segment, the IRU in such Segment shall immediately terminate and all rights of
GTE to use the QWEST System, the GTE Fibers, the Associated Property or any part
thereof relating to such Segment, shall cease and QWEST shall owe GTE no
additional duties or consideration with respect to such Segment. Promptly
thereupon, GTE shall remove all of GTE's electronics, equipment, separate
Regeneration Facilities (as provided pursuant to Section 7.2) and other
associated GTE property from such Segment and any related QWEST facilities at
its sole cost under QWEST's supervision (which supervision shall be without cost
to GTE).
19.3    Notwithstanding the foregoing, no termination or expiration of this
Agreement shall affect the rights or obligations of any party hereto (i) with

20.1    Neither party shall be in default under this Agreement if and to the
extent that any failure or delay in such party's performance of one or more of
its obligations hereunder is caused by any of the following conditions, and such
party's performance of such obligation or obligations shall be excused and

delivery not resulting from the responsible party's failure to timely place
orders therefor (it being expressly acknowledged that the Cable that is being
acquired for and installed in the QWEST System and that will include the GTE
Fibers must include higher fiber counts than that necessary solely for the GTE
Fibers in order to permit completion of the entire QWEST System); lack of or
delay in transportation; government codes, ordinances, laws, rules, regulations
or restrictions (collectively, "Regulations"); war or civil disorder; strikes or
other labor disputes; failure of a third party to grant or recognize an
Underlying Right, or any other cause beyond the reasonable control of such
party; provided that any delay caused by the failure of a third party to grant
an Underlying Right shall constitute a force majeure delay hereunder only to the
extent that such delay does not extend beyond a period of six months (such that
the Estimated Delivery Date with respect to any Segment affected by such delay
shall be extended only up to a period of six months of any such delay, and shall
not be further extended if such delay extends beyond a period of six months).
The party claiming relief under this Article shall notify the other in writing
of the existence of the event relied on and the cessation or termination of said
event.

                              DISPUTE RESOLUTION
21.1    Except as provided in Sections 18.1 and 18.2, if the parties are unable
to resolve any disagreement or dispute arising under or related to this
Agreement, including without limitation, the failure to agree upon any item
requiring a mutual agreement of the parties hereunder, they shall resolve the
disagreement or dispute as follows:
(a)     Officers. Either party may refer the matter to the Chief Executive
Officers or the Chief Operating Officers (the "Officers") of the parties by
giving the other party written notice (a "Notice"). Within fifteen (15) days
after delivery of a Notice, the Officers of both parties shall meet at a
mutually acceptable time and place to exchange relevant information and to
attempt to resolve the dispute.
(b)     Negotiation. If the matter has not been resolved within thirty (30) days
after delivery of such Notice, or if the Officers fail to meet within fifteen
(15) days after delivery of such Notice, either party may initiate mediation
and, if applicable, arbitration in accordance with the procedure set forth in
subsections (c) and (d) below. All negotiations conducted by the Officers
pursuant to this clause are confidential and shall be treated as compromise and
settlement negotiations for purposes of the Federal Rules of Evidence and State
Rules of Evidence.
(c)     Mediation. In the event a dispute exists between the parties and the
respective Officers are unable to resolve the dispute, the parties agree to
participate in a non-binding mediation procedure as follows:
   (i) A mediator will be selected by having counsel for each party agree on a
   single person to act as mediator. The parties' counsel as well as the
   Officers of each party and not more than two other participants from each
   party will appear before the mediator at a time and place determined by the
   mediator, but not more than sixty (60) days after delivery of a Notice. The
   fees of the mediator and other costs of mediation will be shared equally by
   the parties. (ii) Each party's counsel will have forty-five (45) minutes to
   present a review of the issue and argument before the mediator. After each
   counsel's presentation, the other counsel may present specific counter-
   arguments not to exceed ten (10) minutes. The 45-minute and 10-minute periods
   will be exclusive of the time required to answer questions from the mediator
   or attendees. (iii) After both presentations, the Officers may ask questions
   of the other side. At the conclusion of both presentations and the question
   periods, the Officers and their
                                                                         Page 27
<PAGE>

                            CONFIDENTIAL TREATMENT

    counsels will meet together to attempt to resolve the dispute. The length of
    the meeting will be as agreed between the parties. Either party may abandon
    the procedure at the end of the presentations and question periods if they
    feel it is not productive to go further. The mediation procedure is not
    binding on either party.
    (iv)     The duties of the mediator are to be sure that the above set-out
    time periods are adhered to and to ask questions so as to clarify the issues
    and understandings of the parties. The mediator may also offer possible
    resolutions of the issues but has no duty to do so.
   (d)  Arbitration. If the matter is not resolved after applying the mediation
procedures set forth above, or if either party refuses to take part in the
mediation process, the parties hereby agree to submit all controversies, claims
and matters of difference that are unresolved to arbitration in Denver,
Colorado, according to the commercial rules and practices of the American
Arbitration Association ("AAA") from time to time in force, and in accordance
with the following provisions of this subsection (d), and unless otherwise
agreed by the parties and subject to the rights of the parties as provided in
Section 18.1 and Section 18.2 hereof (including the right not to continue to
perform under this Agreement), they shall continue to perform under this
Agreement during arbitration.
   (i)      Arbitration discovery shall be conducted in accordance with the
   Federal Rules of Civil Procedure, with any disputes over the scope of
   discovery to be determined by the arbitrators, it being intended that the
   arbitrators shall allow limited, reasonable discovery prior to any hearing on
   the merits.
   (ii)     Arbitration hereunder shall be by three independent and impartial
   arbitrators. Each of the parties shall appoint one arbitrator within thirty
   (30) days after initiation of arbitration and the two arbitrators so
   appointed shall select a third arbitrator within forty-five (45) days after
   initiation of arbitration. In the event that the parties or the arbitrators
   fail to select arbitrators as required above, the AAA shall select such
   arbitrators.
   (iii)    The AAA shall have the authority to disqualify any arbitrator who it
   determines not to be independent and impartial. The arbitrators shall be
   entitled to a fee commensurate with their fees for professional services
   requiring similar time and effort.
   (iv)     The arbitrators shall conduct a hearing no later than sixty (60)
   days after initiation of the matter to arbitration, and a decision shall be
   rendered by the arbitrators within thirty (30) days of the hearing. At the
   hearing, the parties shall present such evidence and witnesses as they may
   choose, with or without counsel. Adherence to formal rules of evidence shall
   not be required but the arbitration panel shall consider any evidence and
   testimony that it determines to be relevant, in accordance with procedures
   that it determines to be appropriate. The arbitration determination shall be
   in writing and shall specify the factual and legal bases for the
   determination. The arbitrators may award legal or equitable relief, including
   but not limited to specific performance. (v) The parties agree that this
   submission and agreement to arbitrate shall be governed by and specifically
   enforceable in accordance with the laws of the State of Colorado. Arbitration
   may proceed in the absence of any party if prior written notice of the
   proceedings has been given to such party. The parties agree to abide by all
   decisions and determinations rendered in such proceedings. Such decisions and
   determinations shall be final and binding on all parties. All decisions and
   determinations may be filed with the clerk of one or more courts, state,
   federal or foreign having jurisdiction over the party against whom it is
   rendered or its property, as a basis of judgment.

                                                                         Page 28

                            CONFIDENTIAL TREATMENT

 borne by the party against whom the award is rendered, except as the
 arbitration panel may otherwise provide in its written opinion.

                                    WAIVER
22.1    The failure of either party hereto to enforce any of the provisions of
this Agreement, or the waiver thereof in any instance, shall not be construed as
a general waiver or relinquishment on its part of any such provision, but the
same shall nevertheless be and remain in full force and effect.
                                ARTICLE XXIII.
                                 GOVERNING LAW
23.1    This Agreement shall be governed by and construed in accordance with the
domestic laws of the State of Colorado, without reference to its choice of law
principles. Any litigation based hereon, or arising out of or in connection with
a default by either party in the performance of its obligations hereunder, shall
be brought and maintained exclusively in the courts of the State of Colorado or
in the United States District Court for the District of Colorado, and each party
hereby irrevocable submits to the jurisdiction of such courts for the purpose of
any such litigation and irrevocably agrees to be bound by any judgment rendered
thereby in connection with such litigation.

essence in the performance of obligations required to be performed by a date
expressly specified herein. Except as specifically set forth herein, for the
purpose of this Agreement the standards and practices of performance within the
telecommunications industry in the relevant market shall be the measure of a
party's performance.

                     ASSIGNMENT AND TRANSFER RESTRICTIONS
25.1    Except as provided below, QWEST shall not assign, encumber or otherwise
transfer this Agreement or all or any portion of its rights or obligations
hereunder to any other party without the prior written consent of GTE, which
consent will not be unreasonably withheld or delayed. Notwithstanding the
foregoing, QWEST shall have the right, without GTE's consent, to (i) subcontract
any of its construction or maintenance obligations hereunder, or (ii) assign or
otherwise transfer this Agreement in whole or in part (A) as collateral to any
institutional lender to QWEST (or institutional lender to any permitted
transferee or assignee of QWEST) subject to

shall it be restricted from exercising any right of enforcement or foreclosure
with respect to any related security interest or lien, so long as the purchaser
in foreclosure is subject to the provisions of this Agreement, including,
without limitation, this Section 25.1); and provided further that promptly
following any such assignment or transfer, QWEST shall give GTE written notice
identifying the assignee or transferee. In the event of any permitted partial
assignment of any rights hereunder, QWEST shall remain the sole point of contact
with GTE. No permitted partial or complete assignment shall release or discharge
QWEST from its duties and obligations hereunder.

withheld or delayed. Subject to the provisions of Section 25.3 (which provision
shall be binding upon any permitted assignee or transferee hereunder), GTE shall
have the right, without QWEST's consent, to assign or otherwise transfer this
Agreement in whole or in part (i) as collateral to any institutional lender to
GTE (or institutional lender to any permitted transferee or assignee of GTE)
subject to the prior rights and obligations of the parties hereunder, (ii) to
any parent, subsidiary or affiliate of GTE, (iii) to any person, firm or
corporation which shall control, be under the control of or be under common
control with GTE, or (iv) any other entity into which GTE may be merged or
consolidated or which purchases all or substantially all of the stock or assets
of GTE or (v) any partnership, joint venture or other business entity of which
GTE or any wholly owned subsidiary of GTE owns at least 50 percent of the equity
interests thereof and which cannot make major decisions without the consent of
GTE (or subsidiary of GTE); provided that no assignment or other transfer under
this clause (v) shall be permitted hereunder if its purpose or effect would
constitute, directly or indirectly, a Restricted Transaction (as defined in
Section 25.3) or otherwise violate the provisions of Section 25.3; provided that
the assignee or transferee in any such circumstance shall continue to be subject
to all of the provisions of this Agreement, including without limitation this
Section 25.2 and the following Section 25.3 (except that any lender referred to
in clause (i) above shall not incur any obligations under this Agreement, nor
shall it be restricted from exercising any right of enforcement or foreclosure
with respect to any related security interest or lien, so long as the purchaser
in foreclosure is subject to the provisions of this Agreement, including,
without limitation, this Section 25.2 and the following Section 25.3); and
provided further that in any of circumstances described in clauses (ii), (iii)
or (iv) all of the payment obligations of GTE hereunder for the remainder of the
Term shall be fully guaranteed by GTE or shall be paid in full as a condition to
such transfer or assignment; and provided further that promptly following any
such assignment or transfer, GTE shall give QWEST written notice identifying the
assignee or transferee. In the event of any permitted partial assignment of any
rights hereunder, GTE shall remain the sole party and point of contact with
QWEST hereunder.

                                                                         Page 30

                            CONFIDENTIAL TREATMENT

No permitted partial or complete assignment shall release or discharge GTE from
its duties and obligations hereunder.

25.3 Notwithstanding the provisions of Article XI, except as expressly permitted
in Section 25.2(i)-(v), inclusive, without the prior written consent of QWEST,
which consent may be withheld in QWEST's sole discretion, for a period of

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##

following the date that the last Segment of the QWEST System is accepted by GTE:

(a)  GTE shall not sell, assign, lease, grant an IRU with respect to, exchange,
encumber, or otherwise in any manner transfer or make available in any manner to
any third party the ownership, right to use, use of, or access in any manner to,
any of GTE's rights in the whole or discrete GTE Fibers which at the time of
such transaction are Dark Fibers, or engage in substantive discussions or
negotiations with respect thereto, or otherwise engage in a similar transaction
with respect to any GTE Fibers in a manner designed or intended to circumvent
the foregoing limitations.

(b)  GTE shall not sell, assign, lease, grant an IRU with respect to, exchange,
encumber, or otherwise in any manner transfer or make available in any manner to
a Capacity Reseller (as defined below) any of GTE's rights in the whole or
discrete GTE Fibers at a capacity in excess of OC-12, or engage in substantive
discussions or negotiations with respect thereto, or otherwise engage in a
similar transaction with respect to any GTE Fibers in a manner designed or
intended to circumvent the foregoing limitations. As used in this subparagraph,
a Capacity Reseller is any person or entity which, in whole or in part, seeks to
obtain such capacity for the purpose of reselling or otherwise providing access
thereto to third parties for profit, whether or not such person or entity
actually realizes a profit as a result of such transaction.

(c)  Each transaction prohibited in subparagraphs (a) or (b) of this Section
25.3 shall constitute a "Restricted Transaction." Except as provided in
subparagraph (b) of this Section 25.3, nothing contained herein shall restrict
or prohibit GTE from creating telecommunications capacity along or through the
GTE Fibers by the addition of GTE's electronic and optronic equipment and
selling or otherwise permitting third parties to use such telecommunications
capacity.

25.4    QWEST and GTE recognize that QWEST may desire to obtain tax-deferred
exchange treatment pursuant to Section 1031 of the Internal Revenue Code, as
amended, with respect to certain of the Dark Fibers and Associated Property in
which the IRUs are to be granted hereunder and which are used or held for use by
QWEST in its business as of the date hereof (the "Existing Properties"), and GTE
agrees to reasonably cooperate as provided herein in obtaining such treatment
(at no cost or expense to GTE). Accordingly, notwithstanding any provision
contained in this Agreement to the contrary, QWEST may, at its sole option, on
or prior to the Acceptance Date for any relevant Segment, appoint a third party
(the "Intermediary") as agent for QWEST with respect to the transfer of the
Existing Properties to GTE, and assign its rights under this Agreement (insofar
as they relate to the Existing Properties) to such Intermediary. If QWEST so
elects to appoint an Intermediary, QWEST shall notify GTE, in writing, on or
prior to the Acceptance Date with respect to the relevant Segment, and shall
provide GTE with copies of all agreements between QWEST and the Intermediary. If
QWEST appoints an Intermediary, QWEST shall transfer the Existing Properties or
such portion thereof as designated by QWEST to the Intermediary, and GTE shall
pay the IRU Fee with respect to the

                                                                         Page 31
<PAGE>

                            CONFIDENTIAL TREATMENT

Existing Properties (as designated by QWEST) to the Intermediary; provided that
QWEST agrees that such transfer shall be expressly subject to this Agreement,
and that QWEST shall remain liable for performance under this Agreement to the
same extent as if it had not appointed an Intermediary; provided that in such
event QWEST shall indemnify and hold harmless GTE from and against any and all
loss, damage, cost or expense suffered, sustained or incurred by GTE in
connection with any such cooperation and/or payment of such IRU Fee to such
Intermediary.
25.5    This Agreement and each of the parties' respective rights and
obligations under this Agreement, shall be binding upon and shall inure to the
benefit of the parties hereto and each of their respective permitted successors
and assigns.

enforceable against such party in accordance with its terms, subject to

(c)     its execution of and performance under this Agreement shall not violate
any applicable existing regulations, rules, statutes or court orders of any
local, state or federal government agency, court or body.
26.2    QWEST represents and warrants that the Segments of the QWEST System that
it has heretofore constructed or will construct pursuant hereto have been or
shall be designed, engineered, installed, and constructed in compliance with the
terms and provisions of this Agreement and in material compliance with any and
all applicable building, construction and safety codes for such construction and
installation, as well as any and all other applicable governmental laws, codes,
ordinances, statutes and regulations.
26.3    With respect to each of the Segments that has been constructed prior to
the date hereof, QWEST represents and warrants that such Segment, when
constructed, generally was constructed substantially in accordance with the
specifications set forth in Exhibit C hereto, and QWEST has no actual knowledge
on the date hereof of any material deviation in the construction of such Segment
from such specifications. If, within twelve (12) months from the respective
Acceptance Date for each of the Segments referred to in this Section 26.3 ,
there is an event or occurrence that is caused by a material deviation in the
construction or installation of any of such Segments from such specifications,
and which has a material adverse affect on the operation or performance of the
GTE Fibers in such Segment, then, promptly following receipt of written notice
thereof from GTE, QWEST, at its sole cost and expense, shall undertake to repair
the affected portion of such Segment to the relevant specifications.
26.4    QWEST represents and warrants that the Segments of the QWEST System that
it constructs pursuant hereto shall be constructed in all material respects in
accordance with the specifications set forth in Exhibit C hereto; provided that
GTE's sole rights and remedies with respect to any failure to so construct shall
be (i) to inspect the construction, installation and splicing, and participate
in the acceptance testing, of the GTE Fibers incorporated in each such Segment,
during the course and at the time of the relevant construction, installation and
testing periods for each Segment, as provided in Articles III and IV, (ii) if,
during the course of such construction, installation and testing any material
deviation from the specifications set forth in Exhibit C is discovered, the
construction or installation of the affected portion of the Segment shall be
repaired to such specification by QWEST at QWEST's sole cost and expense, and
(iii) if, at any time prior to the date that is twelve (12) months after the
Acceptance Date, GTE shall notify QWEST in writing of its discovery of a
material deviation from the

                                                                         Page 32

specifications set forth in Exhibit C with respect to any such Segment (which
notice shall be given within thirty (30) days of such discovery) the
construction or installation of the affected portion of such Segment shall be
repaired to such specification by QWEST at QWEST's sole cost and expense. For
purposes hereof, "material deviation" means a deviation which is reasonably
likely to have a material adverse affect on the operation or performance of the
GTE Fibers affected thereby.
26.5    EXCEPT AS SET FORTH IN THE FOREGOING PARAGRAPHS 26.2, 26.3 AND 26.4, AND
EXCEPT AS MAY BE SET FORTH SPECIFICALLY AND EXPRESSLY ELSEWHERE IN THIS
AGREEMENT, QWEST MAKES NO WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO THE GTE
FIBERS OR THE SEGMENTS DELIVERABLE HEREUNDER, INCLUDING ANY WARRANTY OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE, AND ALL SUCH WARRANTIES ARE
HEREBY EXPRESSLY DISCLAIMED.
26.7    The parties acknowledge and agree that on and after the relevant
Acceptance Date GTE's sole rights and remedies with respect to any defect in or
failure of the GTE Fibers to perform in accordance with the applicable vendor's
or manufacturer's specifications with respect to the GTE Fibers shall be limited
to the particular vendor's or manufacturer's warranty with respect thereto,
which warranty, to the extent permitted by the terms thereof, shall be assigned
to GTE upon its request. In the event any maintenance or repairs to the QWEST
System are required as a result of a breach of any warranty made by any
manufacturers, contractors or vendors, unless GTE shall elect to pursue such
remedies itself, QWEST shall pursue all remedies against such manufacturers,
contractors or vendors on behalf of GTE, and QWEST shall reimburse GTE's costs
for any maintenance GTE has incurred as a result of any such breach of warranty
to the extent the manufacturer, contractor or vendor has paid such costs.
26.8    QWEST and GTE acknowledge and agree:
(a)     that each grant of the IRU in the GTE Fibers and Associated Property for
a Segment hereunder (each herein called a "Grant") will be treated by each of
them, vis-a-vis the other, as of and after the relevant effective date thereof
as described in Section 6.1, an executed grant to GTE of an interest in real
property with respect to such Segment; and
(b)     that, from and after the effective date of a Grant with respect to a
Segment, no material obligation of either QWEST or GTE will remain to be
performed with respect to such Grant or Segment; and
(c)     that, with respect to each such Grant, this Agreement is not intended as
an executory contract or unexpired lease subject to assumption, rejection, or
assignment by the trustee in bankruptcy of any party to this Agreement,
including, without limitation, assumption, rejection, or assignment under
Bankruptcy Code Section 365.

otherwise seek to impose any liability

 Drawings will be updated with actual field data during and after construction.

 Metro areas scale shall not exceed 1 inch = 200 feet.

 Rural areas scale shall not exceed 1 inch = 500 feet.

 As-builts will be provided within ##MATERIAL OMITTED AND SEPARATELY FILED UNDER
AN APPLICATION FOR CONFIDENTIAL TREATMENT## days after acceptance, in both hard
copy and electronic format (Auto-CAD version 13.0 or later). Updates to the as-
builts will be provided within ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN
APPLICATION FOR CONFIDENTIAL TREATMENT## days of completion of change, like a
relocation project.

13.0  Aerial Construction.

 Subject to prior approval by both parties (which approval shall not be
unreasonably withheld), aerial construction methods will only be used when
buried construction techniques are impractical due to environmental conditions,
schedule or economic considerations, right-of-way issues, or code restrictions.
The parties acknowledge that aerial construction on utility towers (not utility
poles) using optical groundwire or all dielectric self-support methods may be
used without GTE approval provided QWEST agrees to give GTE reasonable prior
notice of its decision to use such aerial methods.

 Aerial design standards and construction techniques will conform with industry-
accepted practices for aerial fiber optic cable systems. All aerial plant must
comply with applicable national (NEC, NESC, etc.), state and local codes.

 The fiber optic cable placed on an aerial system shall be armored and designed
for aerial applications.

 The cable will be placed in accordance with manufacturer specifications. Cable
tension will be monitored during placement. Cable rollers will be placed at a
maximum interval of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION
FOR CONFIDENTIAL TREATMENT## feet. Cable expansion loops will be placed at every
pole. Cable identification/warning tags will be placed at every pole. All cable
splices will be buried in handholes or manholes.

 Cable sheath to suspension strand bonds and grounding will be performed at the
first and last pole of the system and at ##MATERIAL OMITTED AND SEPARATELY FILED
UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## mile intervals.

 Fiber optic cable at all riser poles will be protected with galvanized steel U-
guard from ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT## inches below grade to a point

                                                                         Page 46
<PAGE>

                            CONFIDENTIAL TREATMENT

##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL
TREATMENT## inches below the suspension strand. Conduit sweeps will be used to
transition from the U-guard to either a handhole or manhole.

 All aerial plant will be designed and constructed with 10M EHS (Class A
galvanized) suspension strand unless otherwise dictated by the pole owners or
field conditions. The fiber optic cable will be double lashed to the suspension
strand using 45 mil stainless lashing wire.

 Span length shall account for storm loading (wind and ice) in accordance with
zones outlined in NESC code. Sags and tensions will be calculated in accordance
with industry accepted practices and account for strand size, span length,
ambient temperature at placement and loading. The suspension strand will be
tensioned with a strand dynamometer. A catenary suspension system may be used if
the system exceeds maximum span length specifications.

 Prior to attachment to any existing pole line, the system will be inspected for
compliance with applicable codes and standards, as well as the physical
condition of the poles and existing hardware. Any make-ready work will be
reviewed with the pole owner and specifically addressed prior to construction.

 If a pole line need be constructed, the preferred poles will be Class 4 (40
feet) and Class 5 (35 feet). Use of the preferred poles will make it unnecessary
to calculate pole loading (horizontal, vertical and bending moments) in most
field conditions. Some unusual conditions may require the use of a stronger
class pole. Depth of placement will be dictated by soil conditions, slope of
terrain and length of pole. Poles will be guyed in accordance with industry-
accepted standards. All pole attachment hardware will be galvanized steel.

 Aerial cable will be placed below power attachments and above all other
attachments unless otherwise dictated by the pole owner. Pole contact clearances
and locations will be dictated by current NESC code and the presence of existing
attachments; however, the following minimum objective clearances will apply:

   a)   Power line -##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION
FOR CONFIDENTIAL TREATMENT## inches (below)
   b)   Non-current carrying power line -##MATERIAL OMITTED AND SEPARATELY FILED
UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## inches
   c)   Telephone, CATV and other signal lines -##MATERIAL OMITTED AND
SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## inches
(above) Verticle clearances for crossings or parallel lines will be dictated by
current NESC code; however, the objective clearance for most objects (roads,
alleys, etc.) Is ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION
FOR CONFIDENTIAL TREATMENT## feet (at 100 F) with the exception of railroad
tracks and waterways which have an objective of ##MATERIAL OMITTED AND
SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## feet (at
100 F).

                                                                         Page 47

14.0  Approval of Deviations From Specifications.

QWEST will seek the approval of GTE, which approval shall not be unreasonably
withheld or delayed, prior to undertaking any construction which will deviate
from the Construction Specifications set forth in this Exhibit C.

EXHIBIT D

Fiber Cable Splicing, Testing and Acceptance Procedures
1.    All splices will be performed with an industry-accepted fusion splicing
machine. Qwest will perform two stages of testing during the construction of a
new fiber cable route. Initially, OTDR tests will be taken from one direction.
As soon as fiber connectivity has been achieved to both regen sites, Qwest will
verify and record the continuity of all fibers. Qwest will take and record power
level readings on all fibers in both directions. Qwest will bi-directional OTDR
test all fibers.

2.    During the initial construction, it is only possible to measure the fiber
from one direction. Because of this, splices will be qualified during initial
construction with an OTDR from only one direction. The profile alignment system
or light injection detection system on the fusion splicer may be used to qualify
splices as long as a close correlation to OTDR data is established. The pigtails
will also be qualified at this stage using an OTDR and a minimum 1 km launch
reel. All measurements at this stage in construction will be taken at ##MATERIAL
OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT##
nm.

3.    After Qwest has provided end-to-end connectivity on the fibers, bi-
directional span testing will be done. These measurements must be made after the
splice manhole or handhole is closed in order to check for macro-bending
problems. Continuity tests will be done to verify that no fibers have been
"frogged" or crossed in any of the splice points. Once the pigtails have been
spliced, loss measurements will be recorded using an industry-accepted laser
source and a power meter. OTDR traces will be taken and splice loss measurements
will be recorded. Qwest will also store OTDR traces on diskette and on data
sheets. Laser Precision format will be used on all traces. Qwest will provide
three copies of all data sheets and tables, and one set of diskettes with all
traces.

a.    The power loss measurements shall be made at ##MATERIAL OMITTED AND
SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## nm, and
performed bi-directionally.

b.    OTDR traces shall be taken in both directions at ##MATERIAL OMITTED AND
SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## nm.

 4.   The splicing standards are as follows:

a.    The loss value of the pigtail connector and its associated splice will not
exceed ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT## dB. This value does not include the insertion loss from
its connection to the FDP. For values greater than this, the splice will be
broken and respliced

                                                                         Page 48
<PAGE>

                            CONFIDENTIAL TREATMENT

until an acceptable loss value is achieved. If, after five attempts, Qwest is
not able to produce a loss value less than ##MATERIAL OMITTED AND SEPARATELY
FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## dB, the splice will be
marked as Out-of-Spec ("OOS") on the data sheet. Each splicing attempt shall be
documented on the data sheet.

b.    During initial uni-directional OTDR testing, the objective for each splice
is a loss of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT## or less. If, after three attempts, Qwest is not able to
produce a loss value of less than ##MATERIAL OMITTED AND SEPARATELY FILED UNDER
AN APPLICATION FOR CONFIDENTIAL TREATMENT## dB, then ##MATERIAL OMITTED AND
SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## dB will be
acceptable. If, after two additional attempts, a value of less than ##MATERIAL
OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT##
dB is not achievable, then the splice will be marked as OOS on the data sheet.
Each splicing attempt shall be documented on the data sheet.

c.    During end-to-end testing of a span (a span shall be FDP to FDP), the
objective for each splice is a bi-directional average loss of ##MATERIAL OMITTED
AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL TREATMENT## dB or
less.

d.    The standard for each fiber within a span shall be an average bi-
directional loss of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION
FOR CONFIDENTIAL TREATMENT## dB or less for each splice. For example, if a given
span has 10 splices, each fiber shall have total bi-directional loss (due to the
10 splices) of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT## or less. Each individual splice may have a bi-
directional loss of ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION
FOR CONFIDENTIAL TREATMENT## dB or less, but the average bi-directional splice
loss across the span must be ##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN
APPLICATION FOR CONFIDENTIAL TREATMENT## dB or less.

5.    The entire fiber optic cable system shall be properly protected from
foreign voltage and grounded with an industry-accepted system. The current
system in use by Qwest is depicted in the attached schematic-DWG No. SAH-1
(typical for Surge Arrestor HH Placement).

6.    Customer fiber assignments will be consecutive in count and in a separate
buffer tube (or ribbon or fiber bundles) from others. The maximum number of
fibers within a single buffer tube (or ribbon or fiber bundles) shall be 12.

7.    The fibers shall be terminated to the FDP with Ultra FC-PC connectors,
unless another type of connector is specified. The pigtails shall be
manufactured with the same glass as the backbone cable to minimize splice loss.

                                                                         Page 49

                            CONFIDENTIAL TREATMENT

 Any party responsible for providing maintenance of the Qwest
System hereunder shall be referred to herein as the "Service
Provider".  The Party receiving maintenance services from the
Service Provider hereunder shall be referred to herein as the
"Service Recipient".  All other capitalized terms not otherwise
defined herein shall have their respective meanings as set forth
in the IRU Agreement of which this Exhibit forms a part.

 1.   Maintenance.

      (a)  Scheduled Maintenance.  Routine maintenance and
repair of the Qwest System described in this section ("Scheduled
Maintenance") shall be performed by or under the direction of
Service Provider, at Service Provider's reasonable discretion or
at Service Recipient's request.  Scheduled Maintenance shall
commence with respect to each Segment upon the effective date of
the grant of the IRU therein, as provided in the IRU Agreement.
Scheduled Maintenance shall include the following activities:

           (i)   Patrol of Qwest System route on a regularly
scheduled basis, which will be weekly unless hyrail access is
necessary, in which case, it will be quarterly;

           (ii)  Maintenance of a "Call-Before-You-Dig"
program and all required and related cable locates;

           (iii) Maintenance of sign posts along the
Qwest System right-of-way with the number of the local "Call-Before-
You-Dig" organization and the "800" number for Qwest's
"Call-Before-You-Dig" program; and

           (iv)  Assignment of fiber maintenance technicians
to locations along the route of the Qwest System at approximately
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##
intervals dependent upon terrain and accessability.

      (b)  Unscheduled Maintenance.  Non-routine maintenance
and repair of the Qwest System which is not included as Scheduled
Maintenance ("Unscheduled Maintenance"), shall be performed by or
under the direction of Service Provider.  Unscheduled Maintenance
shall commence with respect to each Segment upon the effective
date of the grant of the IRU therein, as provided in the IRU
Agreement.  Unscheduled Maintenance shall consist of:

           (i)  "Emergency Unscheduled Maintenance" in
response to an alarm identification by Service Provider's
Operations Center, notification by Service Recipient or
notification by any third party of any failure, interruption or
impairment in the operation of the Qwest System, or any event
imminently likely to cause the failure, interruption or
impairment in the operation of the Qwest System.

           (ii) "Non-Emergency Unscheduled Maintenance" in
response to any potential service-affecting situation to prevent
any failure, interruption or impairment in the operation of the
Qwest System.

 Service Recipient shall immediately report the need for
Unscheduled Maintenance to Service Provider in accordance with
procedures promulgated by Service Provider from time to time.
Service Provider will log the time of Service Recipient's report,
verify the problem and dispatch personnel immediately to take
corrective action.

 2.   Operations Center.

                                                                         Page 55
<PAGE>

                            CONFIDENTIAL TREATMENT

   Service Provider shall operate and maintain an
Operations Center ("OC") staffed twenty-four (24) hours a day,
seven (7) days a week by trained and qualified personnel.
Service Provider's maintenance employees shall be available for
dispatch twenty-four (24) hours a day, seven (7) days a week.
Service Provider shall have its first maintenance employee at the
site requiring Emergency Unscheduled Maintenance activity within
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##
after the time Service Provider becomes aware of an event requiring
Emergency Unscheduled Maintenance, unless delayed by
circumstances beyond the reasonable control of Service Provider.
Service Provider shall maintain a toll-free telephone number to
contact personnel at the OC.  Service Provider's OC personnel
shall dispatch maintenance and repair personnel along the system
to handle and repair problems detected in the Qwest System, (i)
through the Service Recipient's remote surveillance equipment and
upon notification by Service Recipient to Service Provider, or
(ii) upon notification by a third party.

 3.   Cooperation and Coordination.

     (a)  Service Recipient shall utilize an Operations
Escalation List, as updated from time to time, to report and seek
immediate initial redress of exceptions noted in the performance
of Service Provider in meeting maintenance service objectives.

     (b)  Service Recipient will, as necessary, arrange for
unescorted access for Service Provider to all sites of the Qwest
System, subject to applicable contractual, underlying real
property and other third-party limitations and restrictions.

     (c)  In performing its services hereunder, Service
Provider shall take workmanlike care to prevent impairment to the
signal continuity and performance of the Qwest System.  The
precautions to be taken by Service Provider shall include
notifications to Service Recipient.  In addition, Service
Provider shall reasonably cooperate with Service Recipient in
sharing information and analyzing the disturbances regarding the
cable and/or fibers.  In the event that any Scheduled or
Unscheduled Maintenance hereunder requires a traffic roll or
reconfiguration involving cable, fiber, electronic equipment, or
regeneration or other facilities of the Service Recipient, then
Service Recipient shall, at Service Provider's reasonable
request, make such personnel of Service Recipient available as
may be necessary in order to accomplish such maintenance, which
personnel shall coordinate and cooperate with Service Provider in
performing such maintenance as required of Service Provider
hereunder.

     (d)  Service Provider shall notify Service Recipient at
least ten (10) business days prior to the date in connection with
any PSWP of any Scheduled Maintenance and as soon as possible
after becoming aware of the need for Unscheduled Maintenance.
Service Recipient shall have the right to be present during the
performance of any Scheduled Maintenance or Unscheduled
Maintenance so long as this requirement does not interfere with
Service Provider's ability to perform its obligations under this
Agreement.  In the event that Scheduled Maintenance is canceled
or delayed for whatever reason as previously notified, Service
Provider shall notify Service Recipient at Service Provider's
earliest opportunity, and will comply with the provisions of the
previous sentence to reschedule any delayed activity.

 4.   Facilities.

      (a)  Service Provider shall maintain the Qwest System

                                                                         Page 56
<PAGE>

                            CONFIDENTIAL TREATMENT

in a manner which will permit Service Recipient's use, in
accordance with the terms and conditions of the IRU Agreement, of
the IRU, the User Fibers and the Associated Property required to
be provided under the terms of the IRU Agreement.

      (b)  Except to the extent otherwise expressly provided
in the IRU Agreement, Service Recipient will be solely
responsible for providing and paying for any and all maintenance
of all electronic, optronic and other equipment, materials and
facilities used by Service Recipient in connection with the
operation of the Dark Fibers, none of which is included in the
maintenance services to be provided hereunder.

 5.   Cable/Fibers.

      (a)  Service Provider shall perform appropriate
Scheduled Maintenance on the Cable contained in the Qwest System
in accordance with Service Provider's then current preventative
maintenance procedures as agreed to by Service Recipient, which
shall not substantially deviate from standard industry practice.

      (b)  Service Provider shall have qualified
representatives on site any time Service Provider has reasonable
advance knowledge that another person or entity is engaging in
construction activities or otherwise digging within five (5) feet
of the Cable.

      (c)  Service Provider shall maintain sufficient
capability to teleconference with Service Recipient during an
Emergency Unscheduled Maintenance in order to provide regular
communications during the repair process.  When correcting or
repairing Cable discontinuity or damage, including but not
limited to in the event of Emergency Unscheduled Maintenance,
Service Provider shall use reasonable efforts to repair traffic-
affecting discontinuity within
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##
after the Service Provider maintenance employee's arrival at the
problem site.  In order to accomplish such objective, it is
acknowledged that the repairs so effected may be temporary in
nature.  In such event, within
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##
after completion of any such Emergency Unscheduled Maintenance,
Service Provider shall commence its planning for permanent
repair, and thereafter promptly shall notify Service Recipient of
such plans, and shall implement such permanent repair within an
appropriate time thereafter.  Restoration of open fibers on fiber
strands not immediately required for service shall be completed
on a mutually agreed-upon schedule.  If the fiber is required for
immediate service, the repair shall be scheduled for the next
available Planned Service Work Period (PSWP).

      (d)  In performing repairs, Service Provider shall
comply with the splicing specifications as set forth in Exhibit
D.  Service Provider shall provide to Service Recipient any
modifications to these specifications as may be necessary or
appropriate in any particular instance for Service Recipient's
approval, which approval shall not be unreasonably withheld.

      (e)  Service Provider's representatives that are
responsible for initial restoration of a cut Cable shall carry on
their vehicles the typically appropriate equipment that would
enable a temporary splice, with the objective of restoring
operating capability in as little time as possible.  Service
Provider shall maintain and supply an inventory of spare Cable in
storage facilities supplied and maintained by Service Provider at

                                                                         Page 57
<PAGE>

                            CONFIDENTIAL TREATMENT

strategic locations to facilitate timely restoration.

 6.   Planned Service Work Period (PSWP).

   Scheduled Maintenance which is reasonably expected to
produce any signal discontinuity must be coordinated between the
parties.  Generally, this work should be scheduled after midnight
and before 6:00 a.m. local time.  Major system work, such as
fiber rolls and hot cuts, will be scheduled for PSWP weekends.  A
calendar showing approved PSWP will be agreed upon in the last
quarter of every year for the year to come.  The intent is to
avoid jeopardy work on the first and last weekends of the month
and high-traffic holidays.

 7.   Restoration.

      (a)  Service Provider shall respond to any interruption
of service or a failure of the Dark Fibers to operate in
accordance with the specifications set forth in Exhibit D (in any
event, an "Outage") as quickly as possible (allowing for delays
caused by circumstances beyond the reasonable control of Service
Provider) in accordance with the procedures set forth herein.

      (b)  When restoring a cut Cable in the Qwest System,
the parties agree to work together to restore all traffic as
quickly as possible.  Service Provider, promptly upon arriving on
the site of the cut, shall determine the course of action to be
taken to restore the Cable and shall begin restoration efforts.
Service Provider shall splice fibers tube by tube or ribbon by
ribbon or fiber bundle by fiber bundle, rotating between tubes or
ribbons operated by the separate Interest Holders (as defined in
paragraph 9(a)), including Service Recipient, in accordance with
the following described priority and rotation mechanics; provided
that, lit fibers in all buffer tubes or ribbons or fiber bundles
shall have priority over any dark fibers in order to allow
transmission systems to come back on line; and provided further
that, Service Provider will continue such restoration efforts
until all lit fibers in all buffer tubes or ribbons are spliced
and all traffic restored.  In general, priority among Interest
Holders affected by a cut shall be determined on a rotating
restoration-by-restoration and Segment-by-Segment basis, to
provide fair and equitable restoration priority to all Interest
Holders, subject only to such restoration priority to which Qwest
is contractually obligated prior to the date of the Agreement.
Service Provider shall use all reasonable efforts to implement a
Qwest System-wide rotation mechanism on a Segment-by-Segment
basis so that the initial rotation order of the Interest Holders
in each Segment is varied (from earlier to later in the order),
such that as restorations occur, each Interest Holder has
approximately equivalent rotation order positions across the
Qwest System.  Additional participants in the Qwest System that
become Interest Holders after the date hereof shall be added to
the restoration rotation mechanism.

      (c)  The goal of emergency restoration splicing shall
be to restore service as quickly as possible.  This may require
the use of some type of mechanical splice, such as the "3M Fiber
Lock" to complete the temporary restoration.  Permanent
restorations will take place as soon as possible after the
temporary splice is complete.

 8.   Subcontracting.

   Service Provider may subcontract any of the maintenance
services hereunder; provided that Service Provider shall require
the subcontractor(s) to perform in accordance with the
requirement and procedures set forth herein.  The use of any such

                                                                         Page 58
<PAGE>

                            CONFIDENTIAL TREATMENT

subcontractor shall not relieve Service Provider of any of its
obligations hereunder.

 9.   Fees and Costs.

      (a)  Scheduled Maintenance Fees.  The fees payable for
any and all Scheduled Maintenance hereunder shall be determined
in accordance with the following provisions.  During any time
after the Acceptance Date for any Segment but subject to
paragraph 10 below, Qwest shall be the Service Provider and
provide Scheduled Maintenance at a cost not to exceed $
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##
per route mile per year, subject to the CPI adjustment described below
(the "Qwest Fixed Fee") and Unscheduled Maintenance as provided
in subparagraph 9 below.  The Scheduled Maintenance fee payable
by Service Recipient shall be equal to a pro rata share of
Qwest's Costs based first upon the number of conduits so
maintained by Qwest and included in such Costs and second upon
the number of Interest Holders (as defined in Section 10.4 of the
Agreement) in the portion of the Qwest System so maintained by
Qwest and included in such Costs; provided however, the total fee
shall in no event exceed the amount of the Qwest Fixed Fee as
adjusted by the CPI-U Adjustment.

 A quarter of the first such Scheduled Maintenance fee with
respect to each Segment will be due and payable thirty (30) days
after the Acceptance Date with respect to such Segment.
Thereafter, one quarter of such fee shall be due quarterly.  All
fees shall be paid by Service Recipient within thirty (30) days
of receipt of invoice therefor.  The Qwest Fixed Fee, if
applicable, may be adjusted annually, in Qwest's Sole discretion,
beginning with the first anniversary date of the execution date
of this Agreement, for increases in the United States Bureau of
Labor Statistics, CPI-U All Services Index (unadjusted), as
originally published.  Said adjustment shall be hereinafter
referred to as "CPI-U Adjustment".  Such fee, as adjusted by the
CPI-U Adjustment, shall be equal to the product of the fee
specified herein multiplied by the fraction (i) whose numerator
is the CPI-U All Services for March of the previous calendar year
for which the adjustment to the fee is being made, and (ii) whose
denominator is the CPI-U All Services for March of the preceding
year.  The adjusted fee shall remain in effect until the next
annual fee is due, when a new adjusted fee fixed pursuant to this
provision shall become effective.  In no event shall the amount
of the fee as adjusted pursuant to this provision be less than
the amount of fee in effect for the immediately-preceding year.
The parties agree that the Index for March 1995 is defined as
151.4.  In the event that the Bureau of Labor Statistics (or any
successor organization) changes the current base of the CPI-U
from 1982-84 = 100, the calculation of a fee under this provision
shall be adjusted to ensure that Qwest receives the same amount
as it would have had, had the base not been changed.  In the
event the Bureau of Labor Statistics (or any successor
organization) no longer publishes the CPI-U, Qwest may, subject
to Service Recipient's agreement (which shall not be unreasonably
withheld), designate the statistical index it deems most
appropriate for collocation of adjustments to a fee and, from the
date the CPI-U ceased to be published, such index shall be used
to make adjustments in a fee under this provision.

      (b)  Unscheduled Maintenance Fees.  If the aggregate
amount of the Costs of Unscheduled Maintenance required as a
result of any single event or multiple, closely-related events is
less than
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##

                                                                         Page 59
<PAGE>

                            CONFIDENTIAL TREATMENT

, such Costs shall be borne by Service Provider.  For any other
Unscheduled Maintenance, the Costs thereof shall be allocated
among the various Interest Holders in the conduit, cable an/or
fibers affected thereby as follows: (i) Costs of Unscheduled
Maintenance solely to or affecting a conduit or cable which
houses fibers of a single Interest Holder shall be borne 100% by
such Interest Holder; (ii) Costs of Unscheduled Maintenance to or
affecting a conduit which houses multiple innerduct conduits, not
including such Costs attributable to the repair or replacement of
fiber therein, shall be borne proportionately by the Interest
Holds in each of the affected innerduct conduits based on the
ratio that such affected conduit bears to the total number of
affected innerduct conduits, and (iii) Costs of Unscheduled
Maintenance attributable to the repair or replacement of fiber,
including the acquisition, installation, inspection, testing and
splicing thereof, shall be borne proportionately by the Interest
Holders in the affected fiber, based on the ratio that the number
of affected fibers subject to the interest of each such Interest
Holder bears to the total number of affected fibers.  All such
Costs which are allocated to Service Recipient pursuant to the
foregoing provisions shall be the responsibility of and paid by
Service Recipient within thirty (30) days after its receipt from
Service Provider of an invoice therefor.

     (c)  Costs.  "Costs" means the actual, direct costs
paid or payable in accordance with the established accounting
procedures generally used by each party, as the case may be, and
which it utilizes in billing third parties for reimbursable
projects, which costs shall include, without limitation, the
following:  (i) labor costs, including wages and salaries, and
benefits and overhead allocable to such labor costs (overhead
allocation percentage shall not exceed the lesser of (x) the
percentage Service Provider typically allocates to its internal
projects or (y)
##MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR
CONFIDENTIAL TREATMENT##
, and (ii) other direct costs and out-of-pocket expenses on a pass-
through basis (e.g., equipment, materials, supplies, contract
services, etc.).

 10.  Term.

      (a)  Service Provider's obligation to perform
maintenance on the relevant portion of the Qwest System shall be
for an initial term expiring June 30, 2006. Qwest shall be the
Service Provider.  Thereafter, Qwest shall have no obligation to
provide Scheduled or Unscheduled Maintenance hereunder, but shall
be entitled to continue to provide maintenance under the terms
and conditions of this agreement.

      (b)  Notwithstanding Section 10(a) above, Qwest
represents and warrants that it shall either (1) make a proposal
not later than June 30, 2004, to the several Service Recipients
to continue to serve as the Service Provider for the services
described in this Exhibit H under commercially reasonable terms
for the remainder of the Minimum Period following June 30, 2006,
or (2) provide notice to the Service Recipients that Qwest shall
not continue to provide those services beyond June 30, 2006.
Should Qwest make a proposal under clause (1), the Service
Recipients and Qwest shall negotiate in good faith toward
reaching agreement on those services.  If the parties have not
concluded an agreement for continuing services by December 31,
2004, the Service Recipients shall be entitled to solicit
proposals from other vendors and may select whichever vendor or
vendors they jointly agree to use for all or separate portions of
the Qwest System and Service Recipient's fibers and Associated
Property, to include Qwest or separate vendors as each Service

                                                                         Page 60
<PAGE>

                            CONFIDENTIAL TREATMENT

Recipient individually selects for its portion of the Qwest System and for its
own fibers and Associated Property. Should Qwest provide notice under clause
(2), the Service Recipients may solicit proposals from other vendors and may
select another vendor or vendors to assume after June 30, 2006, the Service
Provider responsibilities, and Qwest agrees to cooperate fully in the
negotiations and transition period.

                     from their respective obligations under this Agreement
                     (including with respect to the installed Dedicated Dial-Up
                     Access Ports previously provided under the Original
                     Agreement that Vendor is obligated to continue to provide

     as terminated earlier or so extended, the "Term").  Each Schedule to the
     Agreement shall be effective for the period of time during the Term set
     forth in such Schedule.

3.   PROVISION OF SERVICES

     3.1. General.
          -------

          (a)  This Agreement sets forth the terms and conditions under which
               Customer may purchase Services from Vendor. Customer may utilize
               the Services purchased hereunder for any lawful purpose including
               in connection with any service or product offering made available
               by Customer or its Special Affiliates during the Term, providing
               access to an AOL Information Service, providing the delivery of
               Internet access or providing other subscriber-related services to
               end-users. The Parties acknowledge that this Agreement does not:
               (a) grant to Vendor an exclusive privilege to sell or otherwise
               provide to Customer any products or services, or (b) except as
               otherwise provided by Section 3.2 of the Master Agreement, or as
               otherwise required by this Master Agreement or any of the
               Schedules, restrict Vendor from providing products or services to
               other customers of Vendor. Customer may contract with other
               suppliers for the procurement of any products or services.

          (b)  Customer shall (i) remain the single point-of-contact with Vendor
               with respect to those Services provided to Special Affiliates
               pursuant to this Agreement, including with respect to any claims,
               disputes or other actions that Special Affiliates desire to make
               against Vendor, (ii) remain obligated to perform its payment
               obligations under the Agreement with respect to those Services
               provided by Vendor to Special Affiliates pursuant to this
               Agreement, and (iii) Customer agrees to indemnify and hold Vendor
               harmless for claims brought against Vendor by Special Affiliates
               associated with the Services provided by

                       CONFIDENTIAL TREATMENT REQUESTED


               Vendor to Special Affiliates pursuant to this Agreement;
               provided, however, that nothing herein applies to claims brought
               directly by Customer for damages arising out of Services utilized
               by Special Affiliates. For purposes of the Agreement, Services
               provided to Special Affiliates pursuant to this Agreement shall
               be deemed to be Services provided to Customer.

3.2. Resale of Dedicated Resources.
     -----------------------------

     Except as specifically set forth in Schedule B with respect to the
     Dedicated Dial-Up Services, Vendor shall not resell or offer to resell any
     dedicated Services ordered and accepted by Customer regardless of whether
     or not such Services are utilized by Customer.

3.3. Sale of Vendor Network.
     ----------------------

(a)       Notwithstanding anything to the contrary in this Agreement, Customer
     shall have the right of first refusal with respect to any sale or transfer
     other than to a Vendor Affiliate of any unit or division that has, as its
     primary business, the provision of Dedicated Dial-Up Access Services to
     Customer and has Dedicated Dial-Up Access Ports to Customer; provided,
     however, in no event shall Customer have such right of first refusal in
     connection with (i) the sale or transfer of a business unit that does not
     relate to the provision of Services to Customer or (ii) the sale or
     transfer of any Vendor assets to any entity created as a result of, or
     arising out of, the closing of the proposed merger of GTE Corporation and
     Bell Atlantic Corporation so long as the management of Vendor continues to
     have primary management responsibility of the new entity; provided further,
     however, that any transaction in which any assets of Vendor are transferred
     back to any Affiliate of the combined GTE/Bell Atlantic corporation shall
     not be covered by this Section.

4.   ORDERING

     4.1. General.

          The ordering of Services by Customer and the delivery of such Services
          by Vendor shall be governed by the terms and conditions set forth in

               performance of Services for Customer, the cost of which is
               separately charged to, and reimbursed by, Customer shall be
               jointly owned by Vendor and Customer, with no duty of accounting.

          (c)  All right, title and interest in software jointly developed by

          Except to the extent that Customer owns or has rights in certain

     8.1. General.
          -------

                                    Page 4
<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED


          Charges for a Service hereunder shall not begin to accrue until after
          Final Acceptance of the Service.  Charges for any Service shall be as
          computed pursuant to the Schedule of this Agreement corresponding to
          such Service.  All charges specified in the Schedules fully compensate
          Vendor for Services.  Customer will not be liable to Vendor for any
          charges not expressly set forth in the Schedules or the Master
          Agreement unless such charges are mutually agreed upon by the Parties
          in writing.  Customer shall only be obligated to pay for Services
          provided in accordance with the terms of this Agreement.

     8.2. Taxes.
          -----

          The Parties' respective responsibilities for taxes arising under or in
          connection with this Agreement shall be as follows:

          (a)  Vendor shall be responsible for any sales, use, excise, value-
               added, services, consumption, and other taxes and duties payable
               by Vendor on any goods or services that are used or consumed by
               Vendor in providing the Services where the tax is imposed on
               Vendor's acquisition or use of such goods or services and the
               amount of tax is measured by Vendor's costs in acquiring such
               goods or services.

          (b)  Customer shall be responsible for any sales, use, excise, value-
               added, services, consumption, or other tax that is assessed on
               any particular Service received by Customer from Vendor. Customer
               shall also be responsible for any sales, use, excise, value-added
               or consumption taxes imposed on goods purchased by Customer from
               Vendor under the Agreement. If and to the extent any tax
               described in this Subsection (b) is reduced or eliminated during
               the Term, Vendor shall reduce or eliminate any charges for such
               taxes, as appropriate. If and to the extent any tax described in
               this Subsection (b) is increased during the Term, or a new tax is
               imposed upon any particular Service received by Customer from
               Vendor, then Customer shall have full responsibility for such
               increase or tax.

          (c)  The Parties agree to cooperate with each other to enable each to
               more accurately determine its own tax liability. Neither Party
               will act unreasonably in assisting the other Party in minimizing,
               to the extent legally permissible, such other Party's tax
               liability to the extent legally permissible. Each Party shall
               provide and make available to the other any resale certificates,
               information regarding out-of-state or out-of-country sales or use
               of equipment, materials or services, and other exemption
               certificates or information reasonably requested by either Party.

          (d)  Each Party shall promptly notify the other Party of, and
               coordinate with the other Party the response to and settlement
               of, any claim for taxes asserted by applicable taxing authorities
               for which a Party is responsible hereunder, it being understood
               that with respect to any claim arising out of a form or return
               signed by a Party to this Agreement, such Party shall have the
               right to elect to control the response to and settlement of the
               claim, but the other Party shall have all rights to participate
               in the responses and settlements that are appropriate to its
               potential responsibilities or liabilities. If Customer requests
               Vendor to challenge the imposition of any tax, Customer shall

9.   INVOICING AND PAYMENT

     9.1. Invoicing.
          ---------

          (a)  Vendor will invoice Customer for amounts due under this Agreement
               (including with respect to provision of Services to Special
               Affiliates) on a monthly basis in arrears. Each invoice shall
               contain the same information as provided under the Original
               Agreement immediately prior to the Effective Date of this
               Agreement, additional, similar information with respect to the
               Broadband Backhaul Services and Other Services, and any
               additional information as the Parties may otherwise agree. Each
               invoice will separately state those charges for the Dial-Up
               Access Services that are attributable to the provision of
               backhaul functions. Out-of-Pocket Expenses, if any, and Monthly
               Pass-Through Expenses will be billed monthly based upon actual
               and accrued costs, and such expenses shall be trued up on a
               quarterly basis. Upon any request by Customer, Vendor will
               provide Customer with access to books and records (including
               bills and invoices) from third party providers for all Out-of-
               Pocket Expenses and Monthly Pass-Through Expenses. Any refunds or
               credits arising from an Out-of-Pocket Expense reimbursed by
               Customer or a Monthly Pass-Through Expense shall be remitted to
               Customer, and Vendor shall report and transmit to Customer any
               misdirected refunds or credits.

          (b)  To the extent a credit may be due Customer pursuant to this
               Agreement, Vendor shall provide Customer with an appropriate
               credit against amounts then due and owing; if no further payments
               are due to Vendor, Vendor shall pay such amounts to Customer
               within thirty (30) calendar days. In the event such payment is
               not made to Customer when due, Vendor will pay a late fee equal
               to the lesser of (a)

               one (1) percent of the amount of such charges per month; or (b)
               the maximum amount permissible by law.

          (c)  The detailed accounting of actual and accrued costs described in
               Section 3.D of the Original Agreement will be limited to costs
               incurred in the first quarter of Customer's fiscal year 2000 and
               the final true-up with respect to accrued costs(as described in
               the Original Agreement) will be completed and provided to
               Customer by March 31, 2000; and with respect to actual costs,
               Vendor will use all commercially reasonable efforts to work with
               its providers to reconcile actual costs as soon as reasonably
               practicable. Subject to Section 8.3 of this Master Agreement and
               to the last sentence of Section 8.1(a)(i) of Schedule B, Vendor
               will invoice Customer for all amounts due under the Original
               Agreement as of the Effective Date, and Customer will pay to
               Vendor such amounts due, in accordance with Section 9.2 of this
               Master Agreement.

     9.2. Payment Due.
          -----------

          Subject to the other provisions of this Article 9, all undisputed
          charges shall be due and payable by Customer within thirty (30)
          calendar days after receipt of a proper invoice for such amount.  In
          the event that any such charges are not received by Vendor within five
          (5) business days after receipt by Customer of written notice from
          Vendor indicating that such charges have not been paid within such
          thirty-day period, then commencing as of the original due date,
          Customer will pay a late fee equal to the lesser of (a) one (1)
          percent of the amount of such charges per month; or (b) the maximum
          amount permissible by law.  All undisputed amounts due and payable to
          Vendor under this Article 9 shall be paid, at Customer's option,
          either (i) by check payable to the order of Vendor or (ii) by
          electronic funds transfer to Vendor from account(s) designated by
          Customer.

     9.3. Accountability.
          --------------

          Both Parties shall maintain complete and accurate records of and
          supporting documentation for the amounts billable or owed and credits
          applicable to either Party under the terms of this Agreement, in
          accordance with generally accepted accounting principles applied on a
          consistent basis.  Both Parties agree to provide the other Party with
          documentation and other information with respect to any amount claimed
          or owed as may be reasonably requested by either Party to verify
          accuracy and compliance with the provisions of this Agreement.

     9.4. Disputed Charges.
          ----------------

          Customer shall pay undisputed charges when such payments are due under
          this Article 9. Customer may withhold payment of particular charges
          that Customer disputes in good faith. To the extent that Vendor is
          entitled to such payment withheld pursuant to resolution of the
          underlying dispute, Customer shall pay to Vendor such payments plus
          any interest accrued from the date such payments are withheld by
          Customer at a rate equal to one percent (1%) per month on the disputed
          amounts. Upon resolution of the dispute against Vendor, Vendor will
          pay Customer interest equal to one percent (1%) per month on the
          amounts overpaid or under-withheld by Customer.

            with, receive, or otherwise have access to Confidential Information
            (as defined below) of or concerning the other Party. As used in this
            Agreement and subject to Section 11.3 of the Master Agreement,

            furnished or made available directly or indirectly by one Party (the
            "Disclosing Party") to the other (the "Receiving Party") relating to
            or disclosed in the course of the negotiation or performance of this
            Agreement, that is, or should be reasonably understood to be,

            data.

     11.2.  Obligations.
            -----------

            (a)  Any proprietary rights in Confidential Information disclosed by
                 a Party shall remain with such Party. Customer and Vendor shall
                 only disclose Confidential Information of the other Party
                 internally on a "need-to-know" basis. Customer and Vendor shall
                 each use at least the same degree of care, but in any event no
                 less than a reasonable degree of care, to prevent disclosing to
                 third parties the Confidential Information of the other as it
                 employs to avoid unauthorized disclosure, publication or
                 dissemination of its own information of a similar nature;
                 provided that a Party may disclose such information to an
                 entity performing or receiving Services hereunder or to an
                 independent third-party auditor on a "need-to-know" basis where
                 (i) the provision or receipt of Services or audit by such
                 entity is authorized under this Agreement, (ii) such disclosure
                 is necessary or otherwise naturally occurs in that entity's
                 scope of responsibility, and (iii) the entity agrees in writing
                 to assume confidentiality restrictions no less

                 stringent than those described in this Section 11.2. Any
                 disclosure to such entity shall be under the terms and
                 conditions as provided herein.

            (b)  Each Party shall take reasonable steps to ensure that its
                 employees, agents and to the extent applicable, third party
                 auditors comply with this Article 11. In the event of any
                 unauthorized disclosure or loss of, or inability to account
                 for, any Confidential Information of the Disclosing Party, the
                 Receiving Party shall promptly, at its own expense: (i) notify
                 the Disclosing Party in writing; (ii) take such actions as may
                 be necessary or reasonably requested by the Disclosing Party to
                 minimize the violation; and (iii) cooperate in all reasonable
                 respects with the Disclosing Party to minimize the violation
                 and any damage resulting therefrom. With respect to any
                 Confidential Information disclosed to the Receiving Party, the
                 nondisclosure obligation shall last for five (5) years from the
                 date of disclosure of such Confidential Information.

     11.3.  Exclusions.
            ----------

            (a)  "Confidential Information" shall exclude any particular
                 information that (i) was, at the time of disclosure to it,
                 lawfully in the public domain; (ii) after disclosure to it, is
                 lawfully published or otherwise lawfully becomes part of the
                 public domain through no fault of the Receiving Party; (iii)
                 except for the material terms of the Agreement, was lawfully in
                 the possession of the Receiving Party at the time of disclosure
                 to it; (iv) was received after disclosure to it from a third
                 party who had a lawful right to disclose such information to it
                 without any obligation to restrict its further use or
                 disclosure; and (v) was independently developed by the
                 Receiving Party without reference to Confidential Information
                 of the Disclosing Party. In addition, a Party shall not be
                 considered to have breached its obligations by disclosing
                 Confidential Information of the other Party to the minimum
                 extent required to satisfy any legal requirement of a competent
                 government body provided that, immediately upon receiving any
                 such request and to the extent that it may legally do so, such
                 Party advises the Disclosing Party promptly and prior to making
                 such disclosure in order that the Disclosing Party may
                 interpose an objection to such disclosure, take action to
                 assure confidential handling of the Confidential Information,
                 or take such other action as it deems appropriate to protect
                 the Confidential Information.

            (b)  Nothing in this Article 11 shall be construed or interpreted as
                 a representation or agreement to restrict assignment or
                 reassignment of a Party's employees. Subject to each Party's
                 obligations under the Agreement, neither Party shall be
                 precluded from participating in business activities that may be
                 competitive with the other Party.

     11.4.  Residual Knowledge.
            ------------------

            Nothing contained in this Agreement shall restrict either Party from
            the use of any ideas, concepts, know-how, methodologies, processes,
            technologies, algorithms or techniques relating to the Services that
            either Party, individually or jointly, develops or discloses under
            this Agreement, provided that in doing so such Party does not breach
            its obligations under this Article or infringe the intellectual
            property rights of the other Party or third parties who have
            licensed or provided materials to such Party.

     11.5.  Customer Data.
            -------------

            (a)  Without limiting Vendor's obligations under Section 11.2 of the

                 to the access and controls it affords to its employees,
                 Affiliates and subcontractors (including the employees of each)
                 to guard against, identify and promptly terminate the

                        current date while operating.

                 (v)    "Year 2000" Noncompliance" means any failure of the

     13.1.  Termination of Master Agreement for Cause.
            -----------------------------------------

            (a)  Customer's Right to Terminate.  In addition to any other rights
                 -----------------------------
                 or remedies to which Customer may be entitled under this
                 Agreement, in the event that:

                 (i)    Vendor commits a material breach of this Agreement,
                        which breach is not cured within thirty (30) calendar
                        days after notice of breach from Customer to Vendor;

                 (ii)   Vendor commits repeated material breaches of this
                        Agreement, even if cured;

                 (iii)  Vendor violates either Section 3.2 (Resale of Dedicated
                        Resources) or Vendor's core obligations with respect to
                        the most-favored customer provisions set forth in the
                        Schedules (e.g., Section 8.3(b) of Schedule B); or

                 (iv)   there is a total or near-total outage of any of the
                        Services that, while it may last fewer than thirty (30)
                        calendar days, is widespread and prolonged enough to
                        justify a reasonable person, considering all relevant
                        industry standards, to terminate the Agreement,

                 then Customer may, at its option and in its sole discretion,
                 exercise the Agreement Termination Right for cause; provided,
                 however, if Customer's termination for cause right is solely
                 related to the Other Services, Customer may only exercise the
                 Agreement Termination Right with respect to the Other Services.
                 In the event of a termination of Customer's obligations with
                 respect to the Purchase Commitments as a result of termination
                 of the Agreement or any Schedule, Customer shall have no
                 further liability to Vendor with respect to such Purchase
                 Commitments. To the extent new services are added to this
                 Agreement, defaults will be as specified therein.

            (b)  Vendor's Right to Terminate.  In addition to any other rights
                 ---------------------------
                 or remedies to which Vendor may be entitled under this
                 Agreement, in the event that

                 (i)    Customer commits a material breach of this Agreement,
                        including non-payment of undisputed amounts due and
                        owing to Vendor in accordance with the terms of this
                        Agreement, which breach is not cured within thirty (30)
                        calendar days after notice of breach from Vendor to
                        Customer; or

                 (ii)   Customer fails to meet its obligations with respect to
                        the Purchase Commitments in accordance with and subject
                        to the terms of this Agreement, which failure is not
                        cured within thirty (30) calendar days after notice of
                        failure from Vendor to Customer; provided, however,
                        Customer shall be deemed not to have failed to meet its
                        Purchase Commitments if it pays Vendor such amounts that
                        Customer would have otherwise had to pay if Customer
                        actually met such Purchase Commitments,

                 then Vendor, at its option and in its sole discretion, may
                 terminate this Agreement; provided, however, if Vendor's
                 termination for cause right is solely

<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED

                    related to the Other Services, Vendor may only exercise the
                    Agreement Termination Right with respect to the Other
                    Services. To the extent new services are added to this
                    Agreement, defaults will be as specified therein.

     13.2. No Implication Against Materiality.
           ----------------------------------

           The inclusion of any provision, obligation or duty in Section 13.1,
           or any statement in this Agreement, that a particular provision,
           obligation or duty is "material" shall not be construed to imply that
           any other provision, obligation or duty in this Agreement is not
           material.

     13.3. Termination for Change of Control.
           ---------------------------------

           In the event of (a) a change in control of Vendor where such control
           is acquired, directly or indirectly, in a single transaction or
           series of related transactions, (b) all or substantially all of the
           assets of Vendor are acquired by or transferred to any entity, or (c)
           Vendor is merged with or into another entity to form a new entity,
           then at any time after any such event, Customer may, at its option
           and in its sole discretion, exercise the Agreement Termination Right;
           provided, however, nothing in this Section shall apply in a change in
           control resulting from or arising out of the closing of the proposed
           merger of GTE Corporation and Bell Atlantic Corporation (including
           any transaction in which any assets of Vendor are transferred back to
           any Affiliate of the combined GTE/Bell Atlantic corporation), unless
           the acquirer or merged entity is (i) a Significant Competitor of
           Customer (as such list of Significant Competitors may be modified
           from time-to-time by Customer on notice following August 31, 2000 to
           add additional significant competitors of Customer) or (ii) one of
           the following entities: MCI Worldcom, Sprint, Qwest or Level 3, or an
           Affiliate of such entities.

     13.4. Termination/Expiration Assistance; Transition Period.
           ----------------------------------------------------

           Upon expiration of this Agreement or any Schedule, or upon any
           termination or cancellation of this Agreement or any Schedule by
           either Party (whether or not for cause), Customer may decommission
           all Services corresponding to the Agreement or any such Schedule, as
           applicable, and Vendor shall (i) provide Customer, or at Customer's
           request Customer's designee, reasonable assistance and consultation
           to enable Customer (or Customer's designee) to ensure a smooth and
           timely transition of network control and management to Customer (as
           applicable), and to transition Customer's purchase of services
           similar to the Services then expiring or being terminated to another
           vendor, and (ii) continue to provide the Services then expiring or
           being terminated to Customer (at prices then in effect as of the date
           of such expiration, termination or cancellation) and otherwise
           perform all of its obligations under this Agreement (such obligations
           described in this Section 13.4 collectively "Transition Assistance")
           for a period (the "Transition Period") to be determined by Customer
           in its sole and absolute discretion; provided, however, that unless
           otherwise specified in a Schedule to the Agreement, the Transition
           Period shall not be longer than twelve (12) months after the
           effective date of such expiration, termination or cancellation. If
           the provision of such Transition Assistance follows a notice of
           termination by Vendor pursuant to Section 13.1(b) of this Master
           Agreement as a result of Customer's non-payment of undisputed amounts
           owed to Vendor, then Customer shall pay Vendor monthly in advance
           plus an equitable portion of the unpaid charges giving rise to
           termination that compensates Vendor for the provision of such
           Transition Assistance.

<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED

           As part of its obligation to provide Transition Assistance, Vendor
           shall include transferring all rights to Customer at no additional
           charge, for Customer and its designees' exclusive use, any telephone
           numbers used in providing the Services so that Customer or its
           designee may utilize such numbers in providing services (subject to
           the provisions of Schedule B regarding Vendor's obligations to obtain
           such telephone numbers for Customer).

14.  LIABILITY AND FORCE MAJEURE

     14.1. Liability Restrictions.
           ----------------------

           The liability restrictions and limitation provisions for each Service
           provided hereunder are set forth in the associated Schedule for such
           Service.

     14.2. Force Majeure.
           -------------

           (a) No Party shall be liable for any default or delay in the
               performance of its obligations under this Agreement if and to the
               extent such default or delay is caused, directly or indirectly,
               by fire, flood, lightning, earthquake, elements of nature or acts
               of God, strikes, lock-outs or other labor disturbance, riots,
               civil disorders, rebellions or revolutions in any country, or any
               other cause beyond the reasonable control of such Party;
               provided, however, that the non-performing Party is without fault
               in causing such default or delay, and such default or delay could
               not have been prevented by reasonable precautions and cannot
               reasonably be circumvented by the non-performing Party through
               the use of alternate sources, workaround plans or other means
               (each a "Force Majeure Event"). The failure of a supplier or
               subcontractor of Vendor to perform under its agreement with
               Vendor shall not constitute a Force Majeure Event for Vendor
               except to the extent such supplier's or subcontractor's failure
               to perform is caused by a Force Majeure Event.

          (b)  In such event the non-performing Party shall be excused from
               further performance or observance of the obligation(s) so
               affected for as long as such circumstances prevail and such Party
               continues to use its commercially reasonable best efforts to
               recommence performance or observance whenever and to whatever
               extent possible without delay. In the event the Vendor is the
               non-performing Party, Customer shall be excused from paying for
               any Services affected by the Force Majeure Event. Any Party so
               delayed in its performance shall immediately notify the Party to
               whom performance is due by telephone (to be confirmed in writing
               within two (2) business days of the inception of such delay) and
               describe at a reasonable level of detail the circumstances
               causing such delay.

15.  INDEMNIFICATION

          Each Party agrees to indemnify, defend and hold harmless the other
          Party and its Affiliates and their respective officers, directors,
          employees, agents, successors, and assigns, from any and all losses,
          liabilities, damages and claims, and all related costs and expenses
          (including reasonable legal fees and disbursements and costs of
          investigation,

                                    Page 14

          litigation, settlement, judgment, interest and penalties) arising
          from, in connection with, or based on allegations of, any of the
          following:

          (a)  third party claims arising from the indemnifying Party's material
               breach of any obligation, representation or warranty under this
               Agreement;

          (b)  any claims of infringement of any patent, trademark, trade
               secret, copyright or other proprietary rights, alleged to have
               occurred based upon the provision by the indemnifying Party of
               materials, services or other resources to the indemnified Party;

          (c)  the death or bodily injury of any agent, employee, customer,
               business invitee, or business visitor of the indemnified Party or
               any other person caused by the tortious conduct of the
               indemnifying Party; or

          (d)  the damage, loss or destruction of any real or tangible personal
               property caused by the tortious conduct of the indemnifying
               Party.

16. GENERAL

    16.1. Binding Nature and Assignment.
          -----------------------------

          This Agreement shall accrue to the benefit of and be binding upon the
          Parties hereto and any purchaser or any successor entity into which
          either Party has been merged or consolidated or to which either Party
          has sold or transferred all or substantially all of its assets.
          Neither Party may, or shall have the power to, assign this Agreement
          or delegate such Party's obligations hereunder without the prior
          written consent of the other, which consent shall not be unreasonably
          withheld or delayed, except that Customer may assign its rights and
          obligations under this Agreement without the approval of Vendor to an
          entity which acquires all or substantially all of the assets of
          Customer, to any Affiliate of Customer, or to a successor in a merger
          or acquisition of Customer.  Notwithstanding anything to the contrary
          in this Section, but not affecting any of Customer's rights under
          Section 13.3, Customer hereby consents to the assignment of this
          Agreement to any entity created as a result of or arising out of the
          closing of the proposed merger of GTE Corporation and Bell Atlantic
          Corporation, including any transaction in which any assets of Vendor
          are transferred back to any Affiliate of the combined GTE/Bell
          Atlantic corporation.

    16.2. Continued Performance and Governing Law.
          ---------------------------------------

          (a)  Each Party agrees to continue performing its obligations under
               this Agreement while any dispute is being resolved except to the
               extent the issue in dispute precludes performance (dispute over
               payment shall not be deemed to preclude performance).

          (b)  This Agreement and performance under it shall be governed by and
               construed in accordance with the laws of the State of Delaware
               without regard to its choice of law principles.

                                   SCHEDULE B

        Dial-Up Access Services, Service Levels, Pricing and Other Terms


1.   TERM

     The term of this Schedule B shall begin on the Effective Date and shall
     expire on December 31, 2006, unless terminated earlier in accordance with
     the Agreement, or extended by mutual written agreement (such period, as
     terminated earlier or so extended, the "Dial-Up Access Term").

2.   ORDERING

     2.1. New Markets.

          Vendor from time to time shall deliver to Customer a listing of any
          new rate centers or calling areas that are in addition to the Existing
          Calling Areas within which Vendor is willing to provide Dial-Up Access
          Services.

     2.2. Customer Submission of Orders.
          -----------------------------

          To order any Dial-Up Access Services, Customer shall submit to Vendor
          an order for such services covering the three-calendar month period
          beginning at least ninety (90) days following submission of the order
          (such three-month period the "Order Fulfillment Period").  Each order
          will set forth the following:

          (a)  the cumulative number of Dedicated Dial-Up Access Ports that
               Vendor must have installed and activated as of the end of each
               calendar month of an Order Fulfillment Period (for each calendar
               month, such number the "Monthly Target"), and

          (b)  the number of incremental Dedicated Dial-Up Access Ports for each
               calling area ordered by Customer during an Order Fulfillment
               Period (for each calling area, the "Area Delivery Target").

          Each order will be clearly marked as such, and will be delivered by
          Customer via electronic mail to such individuals designated in writing
          from time to time by Vendor.  An e-mailed order will be valid only if
          it is submitted by the Vice President of AOLnet Operations, the
          Director for AOLnet Capacity Planning, or a designee of either.

     2.3. Vendor Acceptance or Rejection of Orders.
          ----------------------------------------

          (a)  Acceptance and Rejection Process.
               --------------------------------

               Vendor shall, within ten (10) business days after receipt of a
               valid order pursuant to Section 2.2 of this Schedule B, notify
               Customer of one of the following:

               (i)  its acceptance of such order; or

                              Schedule B - Page 1
<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED

               (ii) its rejection of such order in whole or in part; provided
                    that Vendor may reject an order if and only to the extent
                    (1) the Monthly Target for a calendar month exceeds the
                    prior month's Monthly Target by more than [*Material Omitted
                    and Separately Filed Under an Application for Confidential
                    Treatment] Dedicated Dial-Up Access Ports, (2) such order
                    requests Dial-Up Access Services to be delivered in a New
                    Calling Area, (3) such order does not reflect the same
                    approximate weighted distribution of Dedicated Dial-Up
                    Access Ports across Existing Calling Areas, or (4) such
                    order requests the provision of Dedicated Dial-Up Access
                    Ports in excess of the Dial-Up Purchase Commitment (each of
                    (1), (2), (3) and (4) a "Valid Order Rejection Reason").

               If Vendor fails to provide Customer with such notice within such
               ten-day period, then such order shall be deemed accepted by
               Vendor.  Vendor shall be obligated to deliver, in accordance with
               this Schedule B, the Dial-Up Access Services requested by
               Customer in an order to the extent such order is accepted or
               deemed accepted by Vendor.  If Vendor rejects an order (or a
               portion thereof) for the reason described in Subsection (ii)(3)
               above, following notice of such objection by Vendor, the Parties
               will mutually agree on an equitable resolution consistent with
               the intent of this Section.

          (b)  Rejections by Vendor.
               --------------------

               To the extent that Vendor rejects an order (or portion thereof)
               for any reason other than a Valid Order Rejection Reason, the
               Dial-Up Purchase Commitment shall be reduced by the number of
               Dedicated Dial-Up Access Ports wrongfully rejected by Vendor.

          (c)  Additional Tasking.
               ------------------

               For any Order Fulfillment Period, in the event Vendor requests,
               Customer will provide Vendor with additional tasking of Dedicated
               Dial-Up Access Ports for Existing Calling Areas; provided,
               however, that such additional tasking shall not result in total
               tasking in excess of [*Material Omitted and Separately Filed
               Under an Application for Confidential Treatment] Dedicated Dial-
               Up Access Ports above the Monthly Target for the third month of
               the such Order Fulfillment Period.  Customer will designate the
               Existing Calling Areas in which any of the Dedicated Dial-Up
               Access Ports corresponding to such additional tasking will be
               provided by Vendor.  Any additional tasking shall not affect the
               Monthly Targets.

     2.4. Cancellation Without Cause and Rescheduling of Orders.
          -----------------------------------------------------

          (a)  Pre-Acceptance or Pre-Rejection Cancellation or Modification
               ------------------------------------------------------------
               by Customer.
               -----------

               Prior to acceptance or rejection of an order by Vendor, Customer
               may rescind or modify, in whole or in part in its sole
               discretion, such order.

          (b)  Post-Acceptance Cancellation or Modification by Customer.
               --------------------------------------------------------

                              Schedule B - Page 2
<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED

               (i)  Customer may cancel or modify an Order in whole or in part
                    at any time in its discretion prior to the delivery of the
                    corresponding Dedicated Dial-Up Access Ports set forth in
                    such Order; provided, however, that except to the extent
                    otherwise agreed by Vendor, such cancellation or
                    modification shall not result in circumstances that would
                    constitute a Valid Order Rejection Reason.  For any such
                    cancellation or modification, Customer will pay to Vendor
                    any incremental Out-of-Pocket Expenses actually incurred as
                    a result of such cancellation or modification and that could
                    not reasonably have been avoided by Vendor.  Customer shall
                    have no liability to Vendor for an Order cancelled pursuant
                    to this Subsection (i) other than payment to Vendor of such
                    Out-of-Pocket Expenses.

               (ii) Customer's cancellation or modification of an Order pursuant
                    to this Subsection (b) shall not relieve Customer of its
                    obligations with respect to the Dial-Up Purchase Commitment.
                    In the event of significant changes to an Order by Customer,
                    Vendor may provide Customer with notice of impaired ability
                    to deliver, and the Parties shall mutually agree upon
                    appropriate changes to the Monthly Targets.

     2.5. Delivery.
          --------

          (a)  Notification of Delivery by Vendor.
               ----------------------------------

               Vendor shall only deliver Dedicated Dial-Up Access Ports that
               Vendor reasonably and in good faith believes will satisfy the
               applicable Acceptance Criteria.  Upon delivery of any Dedicated
               Dial-Up Access Port (but no sooner than such delivery), Vendor
               shall provide to Customer notification of such delivery by e-mail
               to the Vice President of AOLnet Operations, the Director for
               AOLnet Capacity Planning, or a designee of either.  For purposes
               of Subsection (e) of Section 2.5, delivery of any Dedicated Dial-
               Up Access Port shall be deemed made upon Customer's receipt of
               such e-mail from Vendor.

          (b)  Early Delivery By Vendor.
               ------------------------

               Vendor may deliver Dedicated Dial-Up Access Ports ordered by
               Customer before the commencement of the corresponding Order
               Fulfillment Period.

          (c)  Initial Testing Failure of Dedicated Dial-Up Access Ports.
               ---------------------------------------------------------

               Notwithstanding the deemed delivery date described in the last
               sentence of Subsection (a) of this Section, if any Dedicated
               Dial-Up Access Port provided in a month is not accepted by
               Customer prior to the 15/th/ day of the next month, then such
               Dedicated Dial-Up Access Port will be deemed not to have been
               delivered during the first month.

          (d)  Delivery of Additional Tasking.
               ------------------------------

               In any month, Customer shall not be required to accept any
               Dedicated Dial-Up Access Ports in excess of [*Material Omitted
               and Separately Filed Under an Application for Confidential
               Treatment] Dedicated Dial-Up Access Ports

                              Schedule B - Page 3
<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED

               above the Monthly Target for such month. With respect to any
               calling area, Customer shall not be required to accept any more
               Dedicated Dial-Up Access Ports in excess of the then-current Area
               Delivery Target for such calling area.

          (e)  Vendor Failures to Deliver.
               --------------------------

               (i)  Failure to Meet Monthly Target. If Vendor fails to deliver
                    ------------------------------
                    the Monthly Target in any month by more than [*Material
                    Omitted and Separately Filed Under an Application for
                    Confidential Treatment] Dedicated Dial-Up Access Ports, then
                    Customer may reduce the Dial-Up Purchase Commitment by the
                    number of Dedicated Dial-Up Access Ports over [*Material
                    Omitted and Separately Filed Under an Application for
                    Confidential Treatment] that Vendor fails to so deliver.

               (ii) Late Delivery.
                    -------------

                    Vendor shall use demonstrable good faith diligent efforts to
                    deliver Dedicated Dial-Up Access Ports in accordance with an
                    Order prior to the end of the corresponding Order
                    Fulfillment Period. Customer may reduce the Dial-Up Purchase
                    Commitment by the number of Dedicated Dial-Up Access Ports
                    included in an Order (A) for which Vendor has not delivered
                    a substantial portion of a Area Delivery Target by the end
                    of the corresponding Order Fulfillment Period and (B) with
                    respect to which Vendor has not used such efforts. In
                    addition, Customer may cancel, at no cost or liability to
                    Customer, the unfilled portion of the Order pertaining to
                    such Dedicated Dial-Up Access Ports. In the event of such
                    cancellation, Customer shall have no payment obligations to
                    Vendor with respect to the Dedicated Dial-Up Access Ports
                    corresponding to the cancelled portion or portions of the
                    Order. Upon Customer's request, Vendor shall provide
                    Customer with information and supporting documentation which
                    demonstrates Vendor's good faith diligent efforts to deliver
                    all Dedicated Dial-Up Access Ports set forth in an Order
                    prior to the end of the corresponding Order Fulfillment
                    Period (e.g., documents showing Vendor's ordering of
                    circuits from an access provider necessary to provision such
                    ordered Dedicated Dial-Up Access Ports as well as the
                    corresponding response from such access providers (e.g.,
                    firm order commitment)).

     2.6. Ordering Process Review.
          -----------------------

          The Parties acknowledge that the ordering process set forth in this
          Article 2 may require modification during the Dial-Up Access Term, and
          that in such event the Parties shall meet to discuss amending this
          Schedule to reflect any mutually agreed-upon modifications.

     2.7. Acceptance Testing and Final Acceptance.
          ---------------------------------------

          (a)  Acceptance Testing.  Dedicated Dial-Up Access Ports ordered
               ------------------
               hereunder will require acceptance testing by Customer as
               described in this Section. Customer will have up to a [*Material
               Omitted and Separately Filed Under an Application for
               Confidential Treatment] business day period from the date

                              Schedule B - Page 4
<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED

          such Dedicated Dial-Up Access Ports are delivered to Customer (the
          "Dial-Up Acceptance Test Period") in which to perform any reasonable
          testing as Customer in its sole discretion deems appropriate to
          determine whether such Dedicated Dial-Up Access Ports conform to their
          applicable Acceptance Criteria (the "Dial-Up Acceptance Testing"). If
          such Dedicated Dial-Up Access Ports meet their applicable Acceptance
          Criteria, Customer will notify Vendor (by electronic mail) that such
          Dedicated Dial-Up Access Ports have received Final Acceptance pursuant
          to Subsection (c) of this Section. Dedicated Dial-Up Access Ports
          activated and accepted by Customer prior to the Effective Date in
          accordance with the Original Agreement will be deemed accepted for
          purposes of this Agreement.

     (b)  Failure to Satisfy Acceptance Criteria.
          --------------------------------------

          (i)   If Dedicated Dial-Up Access Ports fail to conform to their
                Acceptance Criteria (each such failure a "Dial-Up
                Nonconformity"), Customer will notify Vendor within the
                Acceptance Test Period (by electronic mail), specifying the
                nature of the failure in reasonable detail. Vendor will remove
                rejected Dedicated Dial-Up Access Ports from service pending
                further troubleshooting and corrective action. At no additional
                charge to Customer, Vendor shall use commercially reasonable
                efforts to repair, replace or otherwise correct the Dial-Up
                Nonconformity (and any other problems of which it has knowledge)
                as soon as reasonably practicable after receiving notice from
                Customer so that the Dedicated Dial-Up Access Ports meet the
                applicable Acceptance Criteria.

          (ii)  Upon completion of such efforts and Vendor's re-release of
                Dedicated Dial-Up Access Ports to Customer, Customer shall have
                an additional [*Material Omitted and Separately Filed Under an
                Application for Confidential Treatment] business day period to
                retest the re-delivered Dedicated Dial-Up Access Ports to
                determine whether the previously reported Dial-Up Nonconformity
                has been corrected and if such Dedicated Dial-Up Access Ports
                otherwise then meet the applicable Acceptance Criteria. This
                process will be repeated as necessary until all Dial-Up
                Nonconformities are corrected and such Dedicated Dial-Up Access
                Ports meet the applicable Acceptance Criteria.

          (iii) Notwithstanding Subsection (ii) above, if after [*Material
                Omitted and Separately Filed Under an Application for
                Confidential Treatment] attempts for curing Dial-Up
                Nonconformities, Vendor has not delivered such Dedicated Dial-Up
                Access Ports conforming to the applicable Acceptance Criteria,
                then Customer may:

                (1) allow Vendor to continue to try to correct any Dial-Up
                    Nonconformities;

                (2) if mutually agreed upon by the Parties, accept such
                    Dedicated Dial-Up Access Ports in their nonconforming
                    condition and reduce Vendor's charges for such Dedicated
                    Dial-Up Access Ports by a reasonable amount as mutually
                    determined by the

                              Schedule B - Page 5

                              Parties that shall reflect the reduced value of
                              such Dedicated Dial-Up Access Ports; or

                    (3)       (A) cancel, in whole or in part, at no cost or
                              liability to Customer the portion of the
                              corresponding Order that does not conform as of a
                              date specified in a written notice of cancellation
                              issued by Customer, and (B) so long as the Dial-Up
                              Nonconformities affect at least[*Material Omitted
                              and Separately Filed Under an Application for

               ----------

               If Vendor offers Customer or Special Affiliates dial-up access
               services for provision outside of the United States (excluding
               Japan) at market competitive prices and terms:

               (i)  Customer will use commercially reasonable efforts to
                    encourage such Special Affiliates to purchase in the
                    aggregate for all such Special Affiliates [*Material Omitted
                    and Separately Filed Under an Application for Confidential
                    Treatment] Dial-Up Access Ports from Vendor or Vendor's
                    Affiliates at such market competitive prices and terms; and

               (ii) If as of [*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment] such Special
                    Affiliates have not ordered, committed to order or purchase,
                    or actually purchased, in the aggregate for all such Special
                    Affiliates, [*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment] Dial-Up Access Ports
                    from Vendor or Vendor's Affiliates at market competitive
                    prices and terms with durations of at least [*Material
                    Omitted and Separately Filed Under an Application for

                    number of Dedicated Dial-Up Access Ports under this
                    Agreement equal to the difference between [*Material Omitted
                    and Separately Filed Under an Application for Confidential
                    Treatment] Dedicated Dial-Up Access Ports and the actual
                    number of dial-up access ports that such Special Affiliates
                    in the aggregate ordered, committed to order or purchase, or
                    actually ordered from Vendor or Vendor's Affiliates as of
                    such date (as determined utilizing the Normalization
                    Methodology if applicable). Notwithstanding the foregoing,
                    if (1) a Special Affiliate is offered services by a third
                    party similar to the Dial-Up Access Services ordered or
                    purchased pursuant to this Agreement at prices and terms
                    more competitive than those offered by Vendor or Vendor's
                    Affiliates to such Special Affiliate in a country in which
                    Vendor either has operations or has indicated an intent in
                    which to operate, (2) such Special Affiliate, in its sole
                    discretion, requests Vendor to provide Dial-Up Access
                    Services at prices and terms at least as favorable to
                    Special Affiliate as such prices and terms offered by such
                    third party, and (c) Vendor or Vendor's Affiliates declines
                    to provide such services at such prices and terms, then
                    Customer's obligation under this Subsection (c) shall be
                    reduced by the aggregate amount of Dial-Up Access Ports
                    purchased by such Special Affiliate from such third party .

     Customer shall have the right to direct at any time a change in the
     location in which Dial-Up Access Services are provided within Existing
     Calling Areas (including a reallocation of Dedicated Dial-Up Access Ports
     among locations).  In the event that Customer provides Vendor with notice
     of such direction, Vendor shall comply with such direction within a
     reasonable time; provided, however, that (a) any additional reasonable
     costs incurred by Vendor, including any

                SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES
                IN ADVANCE.

                    interface on an access device and the Vendor-managed
                    Customer hub routers during such month, divided by (B) the
                    aggregate number of all data packets introduced into the
                    Vendor Network between the Ethernet interface on an access
                    device and the Vendor-managed Customer hub routers during
                    such calendar month, the result expressed as a percentage.

             (ii)   The Service Level applicable to Packet Loss Percentage shall
                    be as follows:  Packet Loss Percentage for each calendar
                    month of the Term shall be less than [*Material Omitted and
                    Separately Filed Under an Application for Confidential
                    Treatment] percent ([*Material Omitted and Separately Filed
                    Under an Application for Confidential Treatment]%) for such
                    month.  Vendor's performance relative to such

<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED


                    Service Level shall be reported by Customer on a monthly
                    basis for each calendar month.

          (j)  Time to Respond and Time to Restore Service Levels.
               --------------------------------------------------

               (i)  "Time to Respond" means the elapsed time between (i) the
                    time that Customer reports a problem to Vendor with respect
                    to the Services (or the time that Vendor otherwise becomes
                    aware of such a problem), until (ii)  the moment that Vendor
                    notifies appropriate Customer personnel of such problem and
                    of those efforts being undertaken by Vendor to resolve such
                    problem.  "Mean Time to Respond" for a calendar month shall
                    mean the average of all times corresponding to Time To
                    Respond during such calendar month.  "Time to Restore" means
                    the elapsed time between (i) the time that Customer reports
                    a problem to Vendor with respect to the Services (or the
                    time that Vendor otherwise becomes aware of such a problem),
                    until (ii) the moment that the affected Services are
                    restored to normal operations in accordance with applicable
                    Service Levels, Acceptance Criteria and Specifications.
                    "Mean Time to Restore" for a calendar month shall mean the
                    average of all times corresponding to Time To Repair during
                    such calendar month.  "Mean Maximum Time to Restore" for a
                    calendar month shall mean the [*Material Omitted and
                    Separately Filed Under an Application for Confidential
                    Treatment]. Vendor will not close any problem ticket
                    associated with a particular problem until the appropriate
                    Customer representative and a Vendor representative agree
                    that such problem ticket may be closed.

               (ii) The Service Levels applicable to Mean Time to Respond and
                    Mean Time to Restore shall be as follows:

                    (1)  Mean Time to Respond for each calendar month shall be
                         less than [*Material Omitted and Separately Filed Under
                         an Application for Confidential Treatment] minutes;

                    (2)  Mean Time to Restore for each calendar month shall be
                         less than or equal to [*Material Omitted and Separately
                         Filed Under an Application for Confidential Treatment]
                         minutes;

                    (3)  Mean Maximum Time to Restore for each calendar month
                         shall be less than [*Material Omitted and Separately
                         Filed Under an Application for Confidential Treatment]
                         hours.

                    Vendor's performance relative to the foregoing Service
                    Levels shall be reported by Vendor on a monthly basis for
                    each calendar month.

7.2. Failure to Perform.
     ------------------

          If Vendor fails to meet any Service Level, Vendor shall (a) promptly
          notify Customer of such failure (unless Customer first discovered and
          notified Vendor of such failure), (b) investigate and report on the
          causes of the failure; (c) advise Customer, as and to the extent
          requested by Customer, of the status of remedial efforts being
          undertaken with

                             Schedule B - Page 23
<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED

          respect to such failure; (d) take commercially reasonable efforts to
          correct the failure, and begin meeting the Service Levels; and (e)
          take appropriate preventive measures to minimize the likelihood of the
          failure recurring. Notwithstanding the foregoing, Vendor's failure to
          use commercially reasonable efforts to meet or correct Service Level
          failures with respect to the [*Material Omitted and Separately Filed
          Under an Application for Confidential Treatment] in and of itself
          shall not constitute a breach of the Agreement. With respect to those
          Service Levels for which Vendor's performance is measured against
          [*Material Omitted and Separately Filed Under an Application for
          Confidential Treatment], Vendor shall not be deemed in breach of such
          Service Levels to the extent that Customer uses [*Material Omitted and
          Separately Filed Under an Application for Confidential Treatment].

     7.3. Reporting.
          ---------

          Vendor shall provide Customer with the following reports, in a
          detailed format reasonably satisfactory to Customer:

          (a)  Usage Reports, including:

                    Under an Application for Confidential Treatment]

               (ii) Daily reports on percentage of ineffective calls; and

          (b)  Daily reports on [*Material Omitted and Separately Filed Under an
               Application for Confidential Treatment].

          In addition, upon Customer's request, Vendor shall provide Customer
          with [*Material Omitted and Separately Filed Under an Application for
          Confidential Treatment].  In addition, for all other components of the
          Vendor Network that are utilized to provide Dial-Up Access Services
          under this Schedule B, Vendor shall provide to Customer a daily report
          [*Material Omitted and Separately Filed Under an Application for
          Confidential Treatment].  In the event of a Network outage, Vendor
          will work cooperatively with Customer to share additional [*Material
          Omitted and Separately Filed Under an Application for Confidential
          Treatment] which may be pertinent to the analysis and resolution of
          any such outage.

     7.4. Meetings.
          --------

          Vendor and Customer shall hold weekly meetings at Customer's site or
          via telephone conference call (unless otherwise requested by Customer)
          to assess Vendor's performance under this Schedule B.  During
          emergency situations, meetings will be held at least on a daily basis.

     7.5. Periodic Review of Service Levels.
          ---------------------------------

          As requested by Customer or Vendor, Customer and Vendor shall review
          the Service Levels described in this Schedule B and shall make
          mutually agreed-upon adjustments to them as appropriate to reflect
          performance capabilities associated with advances in the technology
          and methods used to provide the Dial-Up Access Services.

8.   PRICING

     This Article 8 describes the methodologies for calculating the charges
     under this Schedule B and relating pricing terms and conditions.  The
     charges calculated pursuant to this Schedule B, and any other charges
     expressly set forth in the Master Agreement, shall fully compensate Vendor
     for the provision of the Dial-Up Access Services.

     8.1. Pricing for Dial-Up Access Services.
          -----------------------------------

          (a)  Monthly EDAP Charge.
               -------------------

               (i)  The monthly recurring charge (such charge, as may be
                    adjusted pursuant to the Agreement, the "Monthly EDAP
                    Charge") for one (1) Dedicated Dial-Up Access Port
                    corresponding to the first [*Material Omitted and Separately
                    Filed Under an Application for Confidential Treatment]
                    Dedicated Dial-Up Access Ports of the Dial-Up Purchase
                    Commitment only (such port an "Existing Dedicated Dial-Up
                    Access Port") shall be set at the Existing DAP Market Price,
                    as set forth in Exhibit B-2, and shall be automatically
                    reduced according to the schedule set forth in Exhibit B-2.
                    In addition, the Monthly EDAP Charge may be further reduced
                    as provided in this Article 8 of this Schedule B.  The
                    Parties acknowledge that the Monthly EDAP Charge described
                    in the first sentence of Article 2 of Exhibit B-2 shall
                    apply retroactively to October 1, 1999, and Vendor shall
                    provide Customer with a refund of any amounts paid for the
                    corresponding Dial-Up Access Services in excess of such
                    price under the Original Agreement.

               (ii) Following a review of the applicable leases (but in no event
                    later than 45 days after the Effective Date), Vendor shall
                    inform Customer as to the extent to which it desires to (1)
                    assume the operating leases for certain modems, racks and
                    cables for the Existing Dedicated Dial-Up Access Ports
                    leased by Customer (collectively the "Leased Items"), and
                    (2) purchase certain modems, racks and cables for the
                    Existing Dedicated Dial-Up Access Ports owned by Customer
                    (collectively, the "Owned Items").  To the extent that the
                    Parties agree, the Parties shall enter into an amendment
                    under which (A) Vendor shall assume the operating leases for
                    the Leased Items, subject to the terms of such leases and to
                    the rights of third parties in such Leased Items, and (B)
                    Customer shall pass to Vendor title for the Owned Items
                    pursuant to economic terms to be mutually agreed upon,
                    subject to Customer's rights in such equipment.  Such
                    amendment shall reflect that, with respect to Vendor's
                    assumption of the leases of the Leased Items, Customer will,
                    on a pass-through expense basis (i.e., without markup), pay
                    leasing  costs as and when required under the terms of the
                    leases for the Leased Items.  Such amendment shall also
                    reflect that any cost savings achieved by Vendor with
                    respect to leasing and capital costs for the Leased Items
                    will be shared equally between Customer and Vendor.  If
                    Vendor decides not to assume the leases for the Leased
                    Items, the rights and obligations of the Parties with
                    respect to the Leased Items shall be as described in the
                    Original Agreement.  If Vendor decides not to purchase the
                    Owned

                             Schedule B - Page 25
<PAGE>

                       CONFIDENTIAL TREATMENT REQUESTED


                    Items, Customer shall continue to bear the actual
                    capital costs of the Owned Items in accordance with the
                    terms of the Original Agreement.

          (b)  Monthly DAP Charge.
               ------------------

               The monthly recurring charge (such charge, as may be reduced
               pursuant to the Agreement,  the "Monthly DAP Charge") for one (1)
               Dedicated Dial-Up Access Port other than an Existing Dedicated
               Dial-Up Access Port shall be set at the DAP Initial Market Price,
               as set forth in Exhibit B-2, and shall be automatically reduced
               according to the schedule set forth in Exhibit B-2.  In addition,
               the Monthly DAP Charge may be further reduced as provided in this
               Article 8 of Schedule B.  The Monthly DAP Charge shall fully
               compensate Vendor for the provision of the corresponding Dial-Up
               Access Services (including all capital costs of providing the
               corresponding Dial-Up Access Services (excluding hub routers
               resident at Customer's data centers)).

          (c)  Additional Bandwidth.
               --------------------

               For each additional [*Material Omitted and Separately Filed Under
               an Application for Confidential Treatment] bps of average
               bandwidth available at peak per user outbound (and [*Material
               Omitted and Separately Filed Under an Application for
               Confidential Treatment] bps inbound) per Dedicated Dial-Up Access
               Port that Customer requests Vendor to provide hereunder, Vendor
               shall provide such additional bandwidth at a charge to Customer
               that is no greater than [*Material Omitted and Separately Filed
               Under an Application for Confidential Treatment] ($[*Material
               Omitted and Separately Filed Under an Application for
               Confidential Treatment]) per Dedicated Dial-Up Access Port per
               month for each additional [*Material Omitted and Separately Filed
               Under an Application for Confidential Treatment] bps of such
               bandwidth.

     8.2. Decommissioning of Dedicated Dial-Up Access Ports.
          -------------------------------------------------

          (a)  Beginning [*Material Omitted and Separately Filed Under an
               Application for Confidential Treatment], Customer may
               decommission Dedicated Dial-Up Access Ports that either
               contribute to the satisfaction of the Dial-Up Purchase Commitment
               or to Customer's satisfaction of its obligation described in
               Section 2.8(c)(ii) of this Schedule B, without liability, subject
               to the following:

               (i)   Customer will provide one hundred twenty (120) days prior
                     written notice of the calling areas in which Dedicated
                     Dial-Up Access Ports are to be decommissioned, as well as
                     the associated quantities of Dedicated Dial-Up Access Ports
                     to be decommissioned in each such area;

               (ii)  the Vendor Decom Share for a calendar quarter shall not (in
                     the cumulative and not more than a de minimis amount)
                     exceed the Other Vendors' Decom Share for such quarter;

               (iii) the decommissioning of Dedicated Dial-Up Access Ports
                     pursuant to this Subsection (a) shall not materially change

                    Existing Calling Areas; and

               (iv) if the decommissioning of Dedicated Dial-Up Access Ports
                    pursuant to this Subsection (a) causes the aggregate number
                    of Dial-Up Access Ports to fall below [*Material Omitted and
                    Separately Filed Under an Application for Confidential
                    Treatment] of the number of Dedicated Dial-Up Access Ports

               Dedicated Dial-Up Access Ports pursuant this Subsection only to
               the extent that the first day of the month in which Final
               Acceptance occurred for such ports is at least twelve (12) months
               prior to the decommissioning date requested by Customer pursuant
               to this Subsection (b).

          (c)  Customer shall not be responsible for any charges for a Dedicated
               Dial-Up Access Port to the extent such charges correspond to the
               time after the requested decommissioning date of which Customer

                    Price Notice, Vendor will respond to Customer by notifying
                    Customer in writing whether it will:

                    (3)  dispute the validity of the proposed New Dial-Up Market
                         Price.

                    (each a "New Dial-Up Market Price Response").  Vendor shall
                    not unreasonably dispute the validity of a proposed New
                    Dial-Up Market Price.

              (iii) Reduction Process.

                         Customer, [*Material Omitted and Separately Filed Under
                         an Application for Confidential Treatment]
                         corresponding to such New Dial-Up Market Price.

                    Notwithstanding the foregoing:

                    (4)  If Vendor accepts the validity of a proposed New Dial-

                    If Vendor declines to reduce the Monthly DAP Charge or the
                    Monthly EDAP Charge to the New Dial-Up Market Price pursuant
                    to clause (2) of Subsection (ii) of this Subsection (a),

                         each such area;

                    (2)  Customer may only decommission a number of Dedicated
                         Dial-Up Access Ports no greater than the number of

                         Dial-Up Access Ports across Existing Calling Areas.

                    (5)  The right to decommission arising from any particular
                         New Dial-Up Market Price Notice shall cease, on a
                         prospective basis if and when Vendor delivers a New
                         Dial-Up Market Price Response, in response to a later
                         New Dial-Up Market Price Notice, accepting a proposed

                         Under an Application for Confidential Treatment] would
                         be reduced to the New Dial-Up Market Price set forth in
                         the corresponding New Dial-Up Market Price Notice, and
                         with respect to such [*Material Omitted and Separately

                         Treatment].

               (3)       Pursuant to Subsection (iii)(2) of this Subsection (a),

                         be reduced to the New Dial-Up Market Price set forth in
                         the corresponding New Dial-Up Market Price Notice, and

                         inconsistent with Subsection (iii)(4) of this
                         Subsection (a), because such reduction was made
                         pursuant to the same New Dial-Up Market Price Notice
                         that reduced the Monthly DAP Charge pursuant to

                         Market Price Notice for which the New Dial-Up Market
                         Price Notice Date is [*Material Omitted and Separately
                         Filed Under an Application for Confidential Treatment],
                         Vendor would be obligated to provide Customer with a
                         New Dial-Up Market Price Response pursuant to
                         Subsection (ii) of this Subsection.  Such obligation
                         would not be contrary to Subsection (iii)(4) of this
                         Subsection (a), because the New Dial-Up Market Price
                         Effective Date for such New Dial-Up Market Price Notice
                         would be [*Material Omitted and Separately Filed Under
                         an Application for Confidential Treatment].   If Vendor
                         accepts such proposed New Dial-Up Market Price pursuant
                         to clause (1) of Subsection (ii) of this Subsection
                         (a), then effective [*Material Omitted and Separately

                         the Monthly DAP Charge for [*Material Omitted and
                         Separately Filed Under an Application for Confidential

                         Price. Further, pursuant to Subsection (iii)(3) of this
                         Subsection (a), as of [*Material Omitted and Separately
                         Filed Under an Application for Confidential Treatment],
                         the Monthly EDAP Charge will be reduced to such New
                         Dial-Up Market Price, and with respect to [*Material
                         Omitted and Separately Filed Under an Application for

                         Customer, [*Material Omitted and Separately Filed Under
                         an Application for Confidential Treatment]

               (i)  As long as the aggregate number of Dial-Up Access Ports then
                    being purchased or ordered by Customer exceeds that of any
                    other customer of Vendor, Vendor shall not provide dial-up
                    access services that are Comparable Dial-Up Services to any

                    terms and conditions more favorable to such Applicable DUP
                    Purchaser than the terms and conditions of this Schedule B
                    and Master Agreement, in each case, without first offering
                    such lower price and other more favorable terms and
                    conditions to Customer, within thirty (30) calendar days of
                    contractually committing to such price and other terms with
                    another customer.  As of the Effective Date, Vendor
                    acknowledges that the aggregate number of Dial-Up Access
                    Ports being purchased or ordered by Customer exceeds that of
                    any other customer of Vendor.  In the event that the
                    aggregate number of Dial-Up Access Ports being purchased or
                    ordered by Customer at any time during the Term does not
                    exceed that of any other customer of Vendor, Vendor shall
                    provide Customer with written notification of such event
                    within thirty (30) calendar days of the occurrence of such
                    event.  For the purposes of this Subsection, prices "charged
                    or available to Customer hereunder" for Dedicated Dial-Up
                    Access Ports shall be determined by [*Material Omitted and
                    Separately Filed Under an Application for Confidential
                    Treatment].  "Applicable DUP Purchaser" shall mean any party
                    (including any Vendor Affiliate that resells Dial-Up Access
                    purchased from Vendor or another Vendor Affiliate) that is
                    obligated to purchase, that actually purchases, or that
                    seeks to purchase from Vendor or its Affiliates Dial-Up
                    Access at any time equivalent to more than [*Material

                    Confidential Treatment] Dial-Up Access Ports.

               (ii) As long as the aggregate number of Dial-Up Access Ports then
                    being purchased or ordered by Customer exceeds that of any

                    Vendor, to the extent that Vendor provides dial-up access
                    services that are not [*Material Omitted and Separately
                    Filed Under an Application for Confidential Treatment, then
                    Vendor shall offer, on a quarterly basis, to provide to
                    Customer such dial-up access services at the prices charged
                    or available to, and upon the terms and conditions
                    applicable to, [*Material Omitted and Separately Filed Under
                    an Application for Confidential Treatment]; provided,
                    however, that if Customer's service requirements would
                    necessitate changes to such terms and conditions, the
                    Parties shall work in good faith to adjust such terms and
                    conditions as mutually agreed to satisfy such requirements.
                    To the extent that Customer accepts such offer of dial-up
                    access services that are not [*Material Omitted and

                    the event of [*Material Omitted and Separately Filed Under
                    an Application for Confidential Treatment], Customer shall
                    have no further liability to Vendor with respect to such
                    portion of the Dial-Up Purchase Commitment replaced pursuant
                    to this Subsection (ii).

          (iii)     As long as the aggregate number of Dial-Up Access Ports then
                    being purchased or ordered by Customer exceeds that of any
                    other customer of Vendor, Vendor shall offer to Customer,
                    Comparable Dial-Up Services provided or offered by any
                    Vendor Affiliate to an Applicable DUP Purchaser (1) at
                    prices that are equal to or lower than those charged or
                    available to such Applicable DUP Purchaser for such
                    services, for a commitment by such Applicable DUP Purchaser
                    to order or purchase volumes, or for actual orders or
                    purchases of volumes, that are in the aggregate equal to or
                    less than the equivalent volumes that Customer is obligated
                    to purchase under the Agreement, and (2) pursuant to terms
                    and conditions that are at least as favorable or more
                    favorable to Customer than the terms and conditions
                    applicable to or available to an Applicable DUP Purchaser.

          (iv)      For any price proposal made by Vendor to Customer at any
                    time during the Term, Vendor shall in good faith represent
                    to Customer in writing whether or not such proposal is being
                    made for reasons that include Vendor's belief that an
                    adjustment may be required pursuant to this Subsection (b).

          (v)       Customer may audit Vendor's compliance with this Subsection
                    (b) pursuant to Article 10 of the Master Agreement.  In the
                    event that Vendor fails to comply with this Subsection (b)
                    (e.g., fails to adjust pricing in accordance with this
                    Subsection (b)), then Vendor shall rebate to Customer, with
                    respect to each Dedicated Dial-Up Access Port

                    provided to the third party purchasing the Comparable Dial-
                    Up Services from Vendor, retroactive to the date Vendor
                    provided the lower price to such third party, together with
                    interest computed in the same manner as described in Section
                    9.2 of the Master Agreement on such rebated amounts from
                    such date.

          (c)  Regulatory Changes Affecting Pricing.
               ------------------------------------

               In the event that any change in applicable Federal regulations
               results in a significant, demonstrable change in Vendor's costs
               to provide the Dial-Up Access Services, then:

               (i)  in the case of a cost increase, Vendor may pass such
                    applicable cost increase along to Customer on an Out-of-
                    Pocket Expense basis so long as such increase is passed
                    along to all of Vendor's other Dial-Up Access customers to
                    which such costs are not prohibited from being passed;
                    provided, however, Customer may elect, with 120 days notice,
                    to decommission in accordance with Subsection (a)(iv) of
                    this Section any of the Dial-Up Access Ports affected by
                    such Federal regulatory cost increase (however, Customer
                    shall not be required to pay such cost increase during the
                    120-day decommissioning notice period); provided further,
                    however, that (A) the decommissioning of Dedicated Dial-Up
                    Access Ports across the Vendor Network pursuant to this
                    Subsection shall be in proportion to the approximate
                    weighted distribution of Dedicated Dial-Up Access Ports
                    across Existing Calling Areas, and (B) the date and,
                    proportional rate restrictions on decommissioning in
                    Subsection (a)(iv) of this Section shall not apply with
                    respect to decommissioning under this Section; and

               (ii) in the event of a cost decrease, Vendor shall pass such
                    decrease to Customer.

               In connection with any such increase or decrease, Vendor shall
               identify the Dial-Up Access Ports affected by such regulatory
               cost change and the amount of the applicable change to the
               Monthly EDAP Charge or Monthly DAP Charge for such affected Dial-
               Up Access Ports.  Any such regulatory cost change passed -through
               to Customer shall take effect as of the first day of the calendar
               month immediately following delivery of the regulatory cost
               change notice and shall continue in effect until the date on
               which the next New Dial-Up Market Price becomes applicable to
               such affected Dial-Up Access Ports.

     8.4. Normalization Methodology And Conversion Of Services.
          ----------------------------------------------------

          (a)  Normalization Methodology.
               -------------------------

               For purposes of Sections 2.8(c) and 8.3(b)(ii) of this Schedule
               B, and for purposes of the definitions of "Other Vendors' Decom
               Share" and "Vendor's Decom Share" set forth in Schedule A, in
               order to normalize a commitment to order or purchase dial-up
               access provided on a usage basis with a commitment to

                       CONFIDENTIAL TREATMENT REQUESTED

               order or purchase Dedicated Dial-Up Access Ports provided under
               this Agreement, a commitment to order or purchase [*Material
               Omitted and Separately Filed Under an Application for
               Confidential Treatment] shall be deemed equivalent to a
               commitment to purchase one (1) Dedicated Dial-Up Access Port for
               such month (such conversion methodology collectively the
               "Normalization Methodology").

          (b)  Conversion of Services.
               ----------------------

               Upon Customer's request, Vendor shall reasonably and in good
               faith discuss with Customer without further obligation the
               modification of the pricing methodologies applicable to the Dial-
               Up Access Services that may be purchased by Customer under this
               Schedule B as necessary to convert certain Dial-Up Access
               Services to hourly or similar usage based pricing.

     8.5. Technological Change.
          --------------------

          Vendor acknowledges that quality of the Dial-Up Access Services is
          critical to the satisfaction of the users of Customer's services and
          will work to minimize any quality issues associated with the rapid
          implementation of new service technologies.

          (a)  Changes in Dial-Up Access Platform.
               ----------------------------------

               (i)   In the event that Vendor determines that an access platform
                     different from that which is used as of the Effective Date
                     to provide Dedicated Dial-Up Access Ports to Customer
                     represents a superior value, or otherwise may make such
                     platform desirable, Vendor may utilize such different
                     access technology; provided, however, that:

               (ii)  Vendor shall provide Customer with notification of such
                     different access technology upon Vendor's determination to
                     utilize such different access technology, which notice
                     shall be provided no less than sixty (60) days' before
                     deploying such change;

               (iii) such different access technology is not utilized in
                     conjunction with then-existing access technology for any
                     given telephone number for more than forty-five (45) days;
                     and

               (iv)  if such different access technology does not provide (or
                     enable Vendor to provide) any reports required under
                     Section 6.3(o) or 7.3(a) of this Schedule B other than the
                     reports described in Section 7.3(a)(i) of this Schedule B,
                     then:

                     (1)  Vendor may deploy not more than [*Material Omitted and
                          Separately Filed Under an Application for Confidential
                          Treatment] such Dedicated Dial-Up Access Ports (in the
                          aggregate for all such different access technologies
                          that do not provide such reports) (each of such ports
                          a "Reportless Port");

                     (2)  with respect to any Reportless Port, Vendor shall use
                          all commercially reasonable efforts to provide such
                          reports as soon

                       CONFIDENTIAL TREATMENT REQUESTED

                         as practicable, but in no event later than [*Material
                         Omitted and Separately Filed Under an Application for
                         Confidential Treatment] after acceptance of such
                         Reportless Port; and

                    (3)  if Vendor is unable to provide such reports for a
                         Reportless Port for [*Material Omitted and Separately
                         Filed Under an Application for Confidential Treatment]
                         days of acceptance of such Reportless Port, then Vendor
                         shall immediately remove from service any such
                         Reportless Port.

               In no event shall Vendor provide any Dedicated Dial-Up Access
               Ports that do not provide the reports described in Section
               7.3(a)(i) of this Schedule B.  Upon the request of Customer,
               Vendor shall identify which access platform is then being
               utilized for each telephone number used to provide Dedicated
               Dial-Up Access Ports.

          (b)  Technology Briefing.
               -------------------

     term or renewal period (such period, as terminated earlier or so extended,
     the "Broadband Term").

2.   CONSTRUCTION OF AGREEMENT WITH RESPECT TO NON-XDSL BROADBAND SERVICES

          (a)    Although this Agreement governs Broadband Backhaul Services for
                 both xDSL and other broadband services, the Parties acknowledge
                 that the particular rights, duties and obligations set forth
                 herein, including service levels, delivery of service, failure
                 to meet service levels, failure to deliver service, the
                 Broadband Specifications, and other provisions, and the impact
                 of such matters on related purchase commitments as well as
                 other rights and remedies, have been worked out in the
                 particular context of xDSL broadband services. Therefore,
                 although the rights, duties and obligations herein apply to
                 broadband services other than xDSL, the Parties agree to
                 negotiate in good faith how certain provisions herein that are
                 stated in terms particularly relevant to xDSL broadband
                 services will apply in the context of broadband services other
                 than xDSL.

          (b)    The Parties acknowledge and agree that with respect to certain
                 Broadband Backhaul Services used to provide any non-xDSL or
                 non-cable broadband service with [*Material Omitted and
                 Separately Filed Under an Application for Confidential
                 Treatment utilized for an xDSL or cable broadband service and
                 for which delivery of such non-xDSL or non-cable service
                 [*Material Omitted and Separately Filed Under an Application
                 for Confidential Treatment], the Other Broadband Purchase
                 Commitment and the pricing set forth in Exhibit C-2 of this
                 Schedule C shall each be adjusted, as mutually agreed, to
                 reflect an appropriate methodology; provided, however, that (i)
                 with respect to the adjustment to the Other Broadband Purchase
                 Commitment, such adjustment shall only be made to reflect such
                 appropriate methodology, and the commitment [*Material Omitted
                 and Separately Filed Under an Application for Confidential
                 Treatment] shall not be increased or reduced but shall be
                 applied to the adjusted methodology, and (ii) Section 7.2 of
                 this Schedule C shall continue to apply to the Other Broadband
                 Purchase Commitment and pricing, as adjusted.

          (a)    Forecasts of Customer's Expected Broadband Backhaul Services
                 ------------------------------------------------------------
                 Needs in New LATAs.  At the start of every calendar quarter,
                 ------------------
                 Customer will provide Vendor with a non-binding forecast that
                 sets forth those New LATAs in which Customer expects it will
                 need Broadband Backhaul Services over the next three (3)
                 calendar quarters.

          (b)    Ordering Broadband Backhaul Services in Existing LATAs.
                 ------------------------------------------------------
                 The Parties shall mutually agree upon the standards and
                 procedures for ordering Broadband Backhaul Services in Existing
                 LATAs (including (i) scheduling procedures, timelines,
                 performance metrics and remedies, (ii) the ongoing sharing of
                 information back and forth between the Parties as appropriate
                 or necessary to maximize efficiencies and minimize provisioning
                 turnarounds times and (iii) such other issues as the Parties
                 may mutually agree). The Parties specifically agree that a
                 principal objective of the ordering process shall be to meet in
                 a timely manner Customer's Subscriber Line demand. The Parties
                 shall mutually agree upon changes from time to time to the
                 ordering process to facilitate the provision of Broadband
                 Backhaul Services to Customer.

          (c)    Launch of Broadband Backhaul Services in New LATAs.
                 --------------------------------------------------
                 Customer shall direct the launch of New LATAs consistent with
                 the timing of the local access provider and Customer becoming
                 ready to provide xDSL service in that LATA. Any time Customer
                 requests that Vendor provision Broadband Backhaul Services in a
                 New LATA, Customer will provide Vendor with notice (each, a
                 "New LATA Notice") specifying such LATA (as applicable), the
                 initial capacity to be provided in such LATA, and the date
                 Customer anticipates it will begin utilizing such Broadband
                 Backhaul Services in such LATA. In the event that Customer
                 notifies Vendor of a requested change in the specifics of a New
                 LATA Notice provided to Vendor, the Parties will mutually agree
                 upon the extent, if any, that (i) such requested change will
                 affect the time period specified in Section 3.2(a) of this
                 Schedule C, and (ii) Customer will pay Vendor Out-of-Pocket
                 Expenses incurred by Vendor as a result of such requested
                 change.

          (d)    Geographic Distribution.  Notwithstanding the foregoing:
                 -----------------------

                 (i)   the distribution of Vendor Broadband Subscriber Lines
                       providing xDSL broadband services will be approximately
                       proportional to the nationwide distribution of all of the
                       Aggregate DSL Subscriber Lines; and

                 (ii)  the distribution of Vendor Broadband Subscriber Lines
                       providing broadband services other than xDSL will be
                       approximately proportional to the nationwide distribution
                       of all of the Aggregate Other Subscriber Lines.

                 For the purposes of this Subsection (d), "distribution" means
                 the distribution of the corresponding Vendor Broadband
                 Subscriber Lines across rural versus urban areas, across the
                 contiguous states of the United States, and between Covered
                 Subscriber Lines and non-Covered Subscriber Lines. In the event
                 that Vendor believes Customer has provided Vendor with tasking
                 that is inconsistent with this Subsection (d), the Parties will
                 mutually agree on an equitable resolution consistent with the
                 intent of this Section. In January and July of each calendar

                       CONFIDENTIAL TREATMENT REQUESTED

                 year, Customer shall provide Vendor with relevant information
                 regarding the distribution of Aggregate Subscriber Lines.

          (e)    Reports on Subscriber Line Activations.  At least once per
                 --------------------------------------
                 week Customer will provide Vendor a report on the number of
                 Vendor Broadband Subscriber Lines activated from each service

                    Separately Filed Under an Application for Confidential
                    Treatment], divided by (ii) the aggregate number of all
                    sessions utilizing the Broadband Backhaul Services
                    commencing during such calendar day, with the result

                    percent ([*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment]%).  Vendor's
                    performance relative to such Service Level shall be reported
                    by Customer on a monthly basis for each calendar month, if
                    technically feasible.

     (a)            If Vendor fails to meet any Service Level, Vendor shall (i)
                    promptly notify Customer of such failure (unless Customer

                    of the status of remedial efforts being undertaken with
                    respect to such failure; (iv) take commercially reasonable
                    efforts to correct the failure, and begin meeting the
                    Service Levels; and (v) take appropriate preventive measures
                    to minimize the likelihood of the failure recurring.

                    correct Service Level failures under this Schedule C during
                    the first six months following the Effective Date shall not
                    constitute a breach of the Agreement.

                    Level failures with respect to the Abnormal Disconnects in
                    and of itself shall not constitute a breach of the

     (d)            Vendor shall not be deemed in breach of such Service Levels
                    to the extent that such breach is attributable to the
                    offered data load from Customer data centers or subscribers
                    exceeding the specified bandwidth per user or Customer
                    having oversubscribed the intra-LATA interconnect circuits.

               (i)  Definitions.

                    (1)  "New Broadband Backhaul Market Price" shall mean the
                         price (or, if applicable, prices and corresponding

                         adjusted to reflect the difference between [*Material
                         Omitted and Separately Filed Under an Application for
                         Confidential Treatment] that (A) do not [*Material

                    (2)  "Broadband Backhaul Market Vendor" shall mean a vendor
                         (not including a Special Affiliate) that [*Material
                         Omitted and Separately Filed Under an Application for
                         Confidential Treatment].  For the purpose of this
                         Subsection, Special Affiliate shall only be deemed to
                         include Subsections (i) and (ii) of the definition of

                    Customer may provide Vendor with notice at any time of a New
                    Broadband Backhaul Market Price (each such notice, a "New

                    notice as determined pursuant to Section 16.4 of the Master
                    Agreement, the "New Broadband Backhaul Market Price Notice

                    calculation and [*Material Omitted and Separately Filed

                    Backhaul Market Price Notice Date corresponding to a New
                    Broadband Backhaul Market Price Notice, Vendor will respond
                    to Customer by notifying Customer in writing whether it
                    will:

                    (1)  accept the validity of the proposed New Broadband
                         Backhaul Market Price and reduce prices to the
                         applicable New Broadband Backhaul Market Price in
                         accordance with Subsection (iii) of this Subsection

                       CONFIDENTIAL TREATMENT REQUESTED

               (2)  accept the validity of the proposed New Broadband Backhaul
                    Market Price and decline to reduce prices to the New
                    Broadband Backhaul Market Price in accordance with
                    Subsection (iii) of this Subsection (a), or

               (3)  dispute the validity of the proposed New Broadband Backhaul
                    Market Price

               (each a "New Broadband Backhaul Market Price Response"). Vendor
               shall not unreasonably dispute the validity of a proposed New
               Broadband Backhaul Market Price.

     (iii)     Reduction Process.

               In the event Vendor accepts a proposed New Broadband Backhaul
               Market Price pursuant to clause (1) of Subsection (ii) of this
               Subsection (a), then effective as of the later of (a) the New
               Broadband Backhaul Market Price Effective Date corresponding to
               such New Broadband Backhaul Market Price Notice, and (b)
               [*Material Omitted and Separately Filed Under an Application for
               Confidential Treatment], the Monthly Per Subscriber Line Charge
               will be reduced to the New Broadband Backhaul Market Price set
               forth in the corresponding New Broadband Backhaul Market Price
               Notice, and with respect to such Broadband Backhaul Services,
               Vendor will, if requested by Customer, [*Material Omitted and
               Separately Filed Under an Application for Confidential Treatment]
               corresponding to such New Broadband Backhaul Market Price;
               provided, however, that Vendor shall not be obligated to reduce
               the Monthly Per Subscriber Line Charge [*Material Omitted and
               Separately Filed Under an Application for Confidential Treatment]
               for which Vendor reduced prices pursuant to this Subsection
               (iii).

               Notwithstanding the foregoing:

               (1)  Vendor shall not be obligated to reduce the Monthly Per
                    Subscriber Line Charge at a rate that is more rapid than the
                    rate at which the [*Material Omitted and Separately Filed
                    Under an Application for Confidential Treatment] provides
                    Customer with [*Material Omitted and Separately Filed Under
                    an Application for Confidential Treatment] relative to the
                    applicable [*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment], as measured
                    monthly.

               Example 1 - [*Material Omitted and Separately Filed Under an
               Application for Confidential Treatment]. For example, if the
               [*Material Omitted and Separately Filed Under an Application for
               Confidential Treatment] at the New Broadband Backhaul Market
               Price, but immediately following the Broadband Backhaul Market
               Price Effective Date, the Broadband Backhaul Market Vendor has
               only provided Customer with [*Material Omitted and Separately
               Filed

                       CONFIDENTIAL TREATMENT REQUESTED

                    Under an Application for Confidential Treatment], then
                    Vendor will only be obligated to reduce the Monthly Per
                    Subscriber Line Charge [*Material Omitted and Separately
                    Filed Under an Application for Confidential Treatment], then
                    Vendor will be obligated to reduce the Monthly Per
                    Subscriber Line Charge for [*Material Omitted and Separately
                    Filed Under an Application for Confidential Treatment].

                    Example 2 - [*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment].  For example, if,
                    instead, [*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment].  If as of the New
                    Broadband Backhaul Market Price Effective Date, [*Material
                    Omitted and Separately Filed Under an Application for
                    Confidential Treatment], then Vendor will only be obligated
                    to reduce the Monthly Per Subscriber Line Charge [*Material
                    Omitted and Separately Filed Under an Application for
                    Confidential Treatment].  If in the following month,
                    [*Material Omitted and Separately Filed Under an Application
                    for Confidential Treatment], then Vendor will be obligated
                    to reduce the Monthly Per Subscriber Line Charge for fifty
                    [*Material Omitted and Separately Filed Under an Application
                    for Confidential Treatment]. If in following month,
                    [*Material Omitted and Separately Filed Under an Application
                    for Confidential Treatment], then Vendor will be obligated
                    to reduce the Monthly Per Subscriber Line Charge [*Material
                    Omitted and Separately Filed Under an Application for
                    Confidential Treatment].  If in the following month,
                    [*Material Omitted and Separately Filed Under an Application
                    for Confidential Treatment]

                    (2)  Vendor shall not be obligated [*Material Omitted and
                         Separately Filed Under an Application for Confidential
                         Treatment] provides [*Material Omitted and Separately
                         Filed Under an Application for Confidential Treatment]
                         relative to the applicable [*Material Omitted and
                         Separately Filed Under an Application for Confidential
                         Treatment].

                    (3)  A New Broadband Backhaul Market Price shall be
                         applicable only during such periods as [*Material
                         Omitted and Separately Filed Under an Application for
                         Confidential Treatment].

               (iv) Decommissioning Process.

                    If Vendor declines to reduce the Monthly Per Subscriber Line
                    Charge to the New Broadband Backhaul Market Price pursuant
                    to clause (2) of Subsection (ii) of this Subsection (a),
                    then Customer may, in its sole discretion, do either or both
                    of the following: (A) terminate the Broadband Backhaul
                    Purchase Commitment, and (B) disconnect Vendor Broadband
                    Subscriber Lines from the Vendor Network, subject to the
                    following restrictions:

                    (1)  Customer will provide [*Material Omitted and Separately
                         Filed Under an Application for Confidential Treatment]

                         associated quantities of Vendor Broadband Subscriber
                         Lines to be disconnected in each such LATA or other
                         geographic area.

                    (2)  Customer may not order the disconnection of Vendor
                         Broadband Backhaul Subscriber Lines from the Vendor
                         Network in amounts greater than the number of the
                         Aggregate Subscriber Lines utilizing Comparable
                         Broadband Backhaul Services that are provided to
                         Customer by other entities at or below such New
                         Broadband Backhaul Market Price.

                    (3)  The disconnection of Vendor Broadband Subscriber Lines
                         from the Vendor Network pursuant to this Subsection
                         7.2(a)(iv) shall result in the same approximate
                         weighted distribution of Vendor Broadband Subscriber
                         Lines across all Existing LATAs.  For the purposes of
                         this Subsection (3), "distribution" means the
                         distribution of the corresponding Subscriber Lines
                         across rural versus urban areas, across the contiguous
                         states of the United States, and between Covered
                         Subscriber Lines and non-Covered Subscriber Lines.

               (v)  Dispute Resolution Process.

                    If Vendor reasonably disputes the validity of the New
                    Broadband Backhaul Market Price pursuant to clause (3) of
                    Subsection (ii) of this Subsection (a), then each Party
                    shall promptly escalate to the senior-executive level all
                    efforts by such Party to resolve such dispute.

          (b)  Most-Favored Customer.

               (i)  As long as the aggregate number of Vendor Broadband
                    Subscriber Lines exceeds that of any other customer of
                    Vendor, Vendor shall not provide Comparable Broadband
                    Backhaul Services to any other Applicable BB Purchaser (1)
                    at prices that are lower than those charged or available to
                    Customer under this Agreement, or (2) pursuant to terms and
                    conditions more favorable to such Applicable BB Purchaser
                    than the terms and conditions of this Schedule C and Master
                    Agreement, in each case, without offering such lower price
                    and other more favorable terms and conditions to Customer
                    within thirty (30) calendar days of contractually committing
                    to such price and other terms with another customer.  For
                    the purposes of this Subsection, prices "charged or
                    available to Customer under this Agreement" for Broadband

                    ordered by Customer at any time during the Broadband Term
                    exceeds that of any other customer of Vendor, Vendor shall
                    provide Customer with written notification of such event

                    Vendor Broadband Subscriber Lines then being purchased or
                    ordered by Customer falls below that of any other customer
                    of Vendor, Vendor shall provide Customer with written
                    notification of such event within thirty (30) calendar days
                    of the occurrence of such event. "Applicable BB Purchaser"
                    shall mean any party (including any Vendor Affiliate that
                    resells Broadband Backhaul Services purchased from Vendor)
                    that is obligated to purchase, that actually purchases, or
                    that seeks to purchase from Vendor Broadband Backhaul
                    Services at any time for more than the Applicable BB Volume
                    for the then-current calendar year. "Applicable BB Volume"
                    means (A) [*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment] subscriber lines,

                    (E) [*Material Omitted and Separately Filed Under an
                    Application for Confidential Treatment] subscriber lines.

          (ii)      As long as the aggregate number of Vendor Broadband
                    Subscriber Lines exceeds that of any other customer of
                    Vendor, to the extent that Vendor provides broadband
                    backhaul services that are not Comparable Broadband Backhaul
                    Services, then Vendor shall offer, on a quarterly basis, to
                    provide to Customer such broadband backhaul services at the
                    prices charged or available to, and upon the terms and
                    conditions applicable to, any Applicable BB Purchaser;
                    provided, however, that if Customer's service requirements
                    would necessitate changes to such terms and conditions, the
                    Parties shall work in good faith to adjust such terms and
                    conditions as mutually agreed to satisfy such requirements.
                    To the extent that Customer accepts such offer of broadband
                    backhaul services that are not Comparable Broadband Backhaul
                    Services from Vendor, Vendor shall provide such services
                    pursuant to a separate Schedule to the Master Agreement,
                    such services shall be deemed Services to which the Master
                    Agreement applies, and such services shall be subject to
                    most-favored customer terms and conditions substantially
                    similar to those set forth in this Subsection (b), and any
                    such services will [*Material Omitted and Separately Filed

                    services that are not Comparable Broadband Backhaul Services
                    include, but are not limited to, an end-to-end broadband
                    service which includes the local loop, and usage-based
                    broadband backhaul services.

          (iii)     As long as the aggregate number of Vendor Subscriber Lines
                    exceeds that of any other customer of Vendor, Vendor shall
                    offer to Customer Comparable Broadband Backhaul Services
                    provided or offered by any Vendor Affiliate to an Applicable
                    BB Purchaser (1) at prices that are equal to or lower than
                    those charged or available to such Applicable BB Purchaser
                    for such services, and (2) pursuant to terms and conditions

               (iv) For any price proposal made by Vendor to Customer at any
                    time during the Term, Vendor shall in good faith represent
                    to Customer in writing whether or not such proposal is being
                    made for reasons that include Vendor's belief that an
                    adjustment may be required pursuant to this Subsection (b).

               (v)  Customer may audit Vendor's compliance with this Subsection
                    (b) pursuant to Article 10 of the Master Agreement.  In the
                    event that Vendor fails to comply with this Subsection (b)
                    (e.g., fails to adjust pricing in accordance with this
                    Subsection (b)), then Vendor shall rebate to Customer, with
                    respect to the aggregate volume of Broadband Backhaul
                    Services purchased hereunder, the difference between (1) the
                    price actually paid by Customer hereunder, and (2) the lower
                    price provided to the Applicable BB Purchaser, retroactive
                    to the date Vendor committed to provide the lower price to
                    such Applicable BB Purchaser, together with interest
                    computed in the same manner as described in Section 9.2 of
                    the Master Agreement on such rebated amounts from such date.

               Treatment].

                       CONFIDENTIAL TREATMENT REQUESTED


                                  SCHEDULE D

                                Other Services


During the Term, Customer will order from Vendor services (excluding Dial-Up
Access Services, Broadband Backhaul Services and Dial-Up Access Services
provided outside of the United States) (such services to be ordered the "Other
Services") such that the aggregate charges paid to Vendor and Vendor's
Affiliates for such Other Services are equal to or greater than [*Material
Omitted and Separately Filed Under an Application for Confidential
Treatment].dollars ($[*Material Omitted and Separately Filed Under an
Application for Confidential Treatment].) (such commitment the "Other Services
Purchase Commitment"); provided, however, that charges payable for such Other
Services ordered or purchased by Customer or a Special Affiliate of Customer
during December 1999 (collectively, the "Pre-Term Private Line Agreements")
shall contribute toward Customer's satisfaction of the Other Services Purchase
Commitment. Any orders or purchases of Other Services shall be subject to terms
and conditions mutually agreed upon by the Parties, which may include terms and
conditions similar to those set forth in the Master Agreement. Any agreement for
Vendor to provide Other Services to Customer that are private line services
(such services collectively the "Private Line Services") shall contain a most-
favored customer provision substantially similar to the one set forth in Section
8.3(b) of Schedule B. In the event that (i) Customer is offered by a third party
services similar to the Private Line Services at prices and terms more
competitive that those offered by Vendor or Vendor's Affiliates to Customer,
(ii) Customer, in its sole discretion, requests Vendor to provide Private Line
Services at prices and terms at least as favorable to Customer as such prices
and terms offered by such third party, and (iii) Vendor or Vendor's Affiliates
declines to provide Private Line Services at such prices and terms, then the
Other Services Purchase Commitment shall be reduced by the aggregate charges
paid to such third party for such services.

                       AGREEMENT FOR TRANSITION SERVICES

This Agreement for Transition Services is made between GTE Service Corporation,
a New York corporation, with offices at 1255 Corporate Drive, Irving, Texas
75038 and its affiliates (individually and collectively "GTE") on one hand, each
only with respect to the Services (defined below) it provides, and Genuity Inc.,
a Delaware corporation, with offices at 3 Van de Graaff Drive, Burlington,
Massachusetts 01803 ("GENUITY"), and its subsidiaries and successors in
interest, on the other hand.

Whereas, GENUITY desires to obtain certain administrative services including
accounting and cash processing, billing, real estate management, and human
resources services on a transitional basis, with the term of the agreement being
one year or as otherwise set forth in a specific statement of work, terminable
by GENUITY at its sole discretion on 120 days notice; and

Whereas, GTE desires to provide such services to GENUITY.

Now therefore, in consideration of the mutual terms and conditions of this
Agreement, the parties agree as follows:

1.   GENERAL.

(a)  Services.  GENUITY desires to obtain certain administrative transitional
     --------
     services on a non-exclusive basis from GTE or an affiliate company of GTE
     under the terms and conditions of this agreement and statements of work
     ("Statements of Work") entered into by the parties (this agreement and all
     attached Statements of work are collectively referred to as the
     "Agreement"), and GTE or its affiliate shall provide to GENUITY such
     administrative transitional services (individually and collectively,
     "Services"). If there is any conflict or inconsistency between the terms
     and conditions of a Statement of Work and the terms and conditions of this
     Agreement (excluding for this purpose the Statements of Work), the terms
     and conditions of the Statement of Work shall control.

(b)  Statements of Work - Generally.  Each of the Statements of Work entered
     -------------------------------
     into by the parties shall: (i) refer expressly to this Agreement; (ii)
     designate the date as of which the provisions of the Statement of Work
     shall be effective and, if applicable, the term or period of time during
     which GTE shall perform Services, provide resources or otherwise discharge
     its obligations as specified in the Statement of Work if different from the
     term set out in this Agreement (excluding for this purpose the Statement of


                                                                   Page 1 of 114
<PAGE>

     Work); (iii) describe the Services to be performed, Work Product (as
     defined herein) to be delivered, resources to be provided or obligations to
     be discharged by GTE pursuant to the Statement of Work; (iv) describe the
     obligations of GENUITY related to the Statement of Work, including any
     facilities, equipment, personnel and tasks or other support to be provided
     or performed by GENUITY; (v) specify the payments to be made to GTE under
     the Statement of Work, or, if applicable, the basis on which such payments
     shall be computed; and (vi) specify any other terms and conditions
     appropriate to the Services to be performed and the obligations of the
     parties. In the event of conflict or inconsistency between the terms and
     conditions of a Statement of Work and the terms and conditions of this
     Agreement (excluding for this purpose the Statement of Work), the terms and
     conditions of the Statement of Work shall control.

(c)  Milestones, Phases and Timing; Changes.  Each of the Statements of Work
     --------------------------------------
     shall set out, if applicable, milestones and phases of the work.  When
     phases are specified, GTE shall not be obligated to proceed with work on
     the next phase until GENUITY has provided written authorization to proceed.
     If GENUITY has not provided GTE with written authorization to proceed on a
     specific phase, and it is necessary to commence or complete such phase in
     order to meet any milestones specified in the Statement of Work, GTE shall
     not have any obligations with respect to such milestones and the Statement
     of Work shall be deemed to be modified accordingly. The Statement of Work
     may be modified by mutual written agreement, signed by both parties. No
     verbal changes to the Statement of Work are permitted.

(d)  Performance.  All Services shall be performed in accordance with the terms
     -----------
     and conditions of this Agreement and the requirements, order of performance
     and delivery dates specified in each Statement of Work.  GTE shall devote
     such time, efforts and resources to the performance of Services as are
     necessary to accomplish the tasks specified in any Statement of Work.  GTE
     may call upon the expertise and/or assistance of its affiliates,
     subcontractors or consultants in the performance of such Services, provided
     that GTE shall obtain the prior written consent of GENUITY in the event it
     desires to use outside subcontractors or consultants.  If a Statement of
     Work specifies that some or all of the work will be done by a
     subcontractors or consultant, no additional approval shall be required.

(e)  Third Party Software Licenses.  GENUITY acknowledges that GTE and its
     -----------------------------
     affiliates may be required to use certain software licensed to GTE by third
     parties to provide Services pursuant to this Agreement.  If any licensor of
     such third party software requires the payment of any


                                                                   Page 2 of 114
<PAGE>

     consideration to permit GTE to use the vendor's software in order to
     perform its obligations under this Agreement, GTE shall provide GENUITY
     with thirty (30) days prior written notice of such additional
     consideration. GENUITY shall have the option to (i) procure its own license
     to such software at its own expense, or (ii) authorize GTE to incur such
     required additional consideration on its behalf and at GENUITY'S expense.
     In the event that GENUITY does not agree to either (i) or (ii) above, GTE
     shall not be required to provide the Services for which such third party
     licenses are required. If the third party requires GENUITY to secure rights
     in such third party software to receive the Services or to use the result
     of such Services, GENUITY shall be responsible for securing such rights at
     its own cost and expense.

2.   COMPENSATION AND BILLING.

(a)  Invoices.  The charges for the Services shall be set out in the applicable
     --------
     Statement of Work. GTE shall invoice GENUITY for Services in accordance
     with the payment schedule set forth in the applicable Statement of Work.
     Each invoice shall reference this Agreement and the applicable Statement of
     Work.  The invoices shall be itemized to show the details as to all billed
     items.  Payments shall be made within thirty (30) days from the date each
     invoice is received by GENUITY.

(b)  Sales, Use and Other Taxes.  In addition to the charges for Services,
     --------------------------
     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 with respect to the Services lawfully
     levied by a duly constituted governmental authority and for which GTE is
     required, by law, to collect from GENUITY.  In addition each party shall be
     responsible for all real and personal property taxes imposed on software
     and equipment owned by the respective parties on January 1 of every year.
     If GENUITY determines that any Services are exempt from a tax, GENUITY must
     provide GTE a properly completed exemption certificate, for each
     jurisdiction for which GENUITY is claiming an exemption, before GTE will
     exclude the respective tax from amounts charged to GENUITY.  GENUITY will
     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.

(c)  Expense Reimbursement.  GENUITY shall reimburse GTE for reasonable expenses
     ---------------------
     for travel, meals and lodging incurred by GTE in the performance of its
     obligations under this Agreement.  Any such


                                                                   Page 3 of 114
<PAGE>

     charges shall be in compliance with GTE's employee expense policies. There
     shall be no mark-up of such expense charges. GTE shall maintain
     documentation of expenses incurred, and shall provide copies of invoices of
     $100 or more upon GENUITY's request. GTE shall bill GENUITY monthly for
     expenses as they accrue. The parties will specify any limitation on the
     reimbursement of expenses in the applicable Statement of Work. It is
     acknowledged and agreed that if GTE is reasonably required to incur
     expenses beyond such limitation in order to provide the Services, then GTE
     is excused from performing such Services until said expense limitation is
     removed or changed as mutually agreed, provided that GTE promptly notifies
     GENUITY of the need to exceed the limitation.

(d)  Records.  GTE shall maintain complete and accurate records in a form
     -------
     consistent with generally accepted accounting practices, to substantiate
     GTE charges.  GTE shall retain, and make available upon request, such
     records for a period of three (3) years from the date of invoice for
     Services.  GENUITY and its authorized agents, subject to obligations of
     confidentiality as set forth in this Agreement, shall have access to such
     records upon prior written request during normal business hours during the
     term of this Agreement and during the respective periods in which GTE is
     required to maintain such records pursuant to this subsection.  Access to
     the records shall be made at the location where such records are normally
     maintained.

3.   TERM.

     This Agreement is effective as of _____________ and shall continue in
     effect for a term of one (1) year, or such term as may be set out in a
     Statement of Work, or until GENUITY exercises its right in its sole
     discretion to terminate for convenience under Section 24 (c) of this
     Agreement. This Agreement shall remain in effect with respect to and for
     the duration of any Statement of Work that is agreed by the parties to
     extend beyond the end of the term.  In the event of any termination or
     expiration, the Parties agree to reasonably cooperate in transitioning the
     work to any successor service provider, and upon GENUITY's request and at
     its expense, GTE shall use commercially reasonable efforts to secure
     GENUITY's continued use of applicable third party licenses.

4.   ACCEPTANCE.

(a)  Acceptance. Each Statement of Work shall specify the criteria that GTE must
     ----------
     meet in order for the Work Products described in the Statement of Work to
     be accepted by GENUITY.  It shall also specify a test plan, and such other
     information as GTE and GENUITY



                                                                   Page 4 of 114
<PAGE>

     mutually deem appropriate and the period of time that GENUITY shall have
     to review such Work Product and provide notice of acceptance or rejection
     to GTE. Failure to accept or reject such Work Product within the
     specified period of time or the commercial use of such Work Product by or
     for the benefit of GENUITY shall be deemed to be acceptance.

(b)  Rejection and Revision.  If GENUITY rejects any Work Product, it shall
     ----------------------
     specify in reasonable detail in writing the reasons for rejection and the
     requirements for revision.  If the notice of rejection is not sufficiently
     detailed to allow GTE to determine why such Work Product is unacceptable,
     GTE may request in writing that GENUITY provide sufficient additional
     information.  If GTE and GENUITY have joint responsibility for the Work
     Product and the Work Product requires revision, GTE shall assist GENUITY in
     making revisions necessary for the Work Product to meet the acceptance
     criteria within a period of time that is reasonable under the
     circumstances.  If GTE has sole responsibility for the Work Product, then
     it shall make the necessary revisions within a period of time that is
     reasonable under the circumstances.

5.   CONFIDENTIAL INFORMATION.

(a)  Confidentiality.  In the course of requesting and performing Services
     ---------------
     pursuant to this Agreement, each party may receive or acquire from the
     other information or data pertaining to specifications, drawings, sketches,
     models, samples, computer programs, methods, concepts, know-how,
     techniques, processes, and other technical or business information that the
     other party desires to protect against unauthorized use or further
     disclosure.  Unless otherwise expressly set forth in a Statement of Work,
     for purposes of this Agreement, "Confidential Information" shall mean:  (i)
     any information in written, other tangible or electronic form which is
     labeled by the disclosing party as "confidential", "proprietary" or with a
     legend of similar import; (ii) software in any form (including related
     documentation), whether or not labeled in accordance with the preceding;
     (iii) Services and Work Products provided pursuant to this Agreement, with
     the ownership of and proprietary interest therein being defined in the
     applicable Statement of Work; or (iv) information orally disclosed and
     identified as confidential at the time of such disclosure which is
     summarized in writing within thirty (30) days of such disclosure.  Each
     party shall remain the exclusive owner of its Confidential Information.

(b)  Use of Confidential Information.  The Confidential Information of the
     -------------------------------
     disclosing party may be used by the receiving party only for the
     performance or use of Services or Work Products to be provided pursuant



                                                                   Page 5 of 114
<PAGE>

     to this Agreement and may only be disclosed to those employees,
     subcontractors or agents of the receiving party who have a need to know in
     order to perform or use Services or Work Products pursuant to this
     Agreement. Except and to the extent set forth in Section 5(c), the
     receiving party may not disclose Confidential Information of the other
     party to any other person, entity, or the public without the prior written
     consent of the disclosing party. However, such Confidential Information may
     be disclosed by the receiving party without the necessity of prior written
     consent, to the receiving party's subcontractors or consultants who require
     access to such Confidential Information to perform or use the Services
     under this Agreement, provided such persons have entered into written
     agreements which contain obligations of nondisclosure and nonuse no less
     restrictive than set forth in this Section. It is agreed that such written
     agreements shall be enforceable by the disclosing party.

(c)  Exceptions.  The obligations in Section 5(b) shall not apply to that
     ----------
     portion of any information received from the disclosing party which is:
     lawfully in the receiving party's possession, with no restriction on use or
     disclosure, prior to its acquisition from the disclosing party; received in
     good faith by the receiving party, with no restrictions on use or
     disclosure, from a third party not subject to any confidential obligation
     to the disclosing party; now or later becomes publicly known through no
     breach of confidential obligation by the receiving party; released by the
     disclosing party to any other person, firm or entity (including
     governmental agencies or bureaus) without restriction on use or disclosure;
     or independently developed by or for the receiving party without any
     reliance on or use of Confidential Information of the disclosing party.

(d)  Disclosure and Notification.  If a receiving party receives a request to
     ---------------------------
     disclose any Confidential Information of the disclosing party (whether
     pursuant to a subpoena, an order issued by a court or other governmental
     authority of competent jurisdiction or otherwise) and, on advice of legal
     counsel, determines that disclosure is required under applicable law, the
     receiving party agrees that, prior to disclosing any Confidential
     Information of the disclosing party, it shall (i) notify the disclosing
     party of the existence and terms of such request or advice, (ii) cooperate
     with the disclosing party in taking legally available steps to resist or
     narrow any such request or to otherwise eliminate the need for such
     disclosure at the disclosing party's sole expense, if requested to do so by
     the disclosing party, and (iii) if disclosure is required, it shall be the
     obligation of the disclosing party to use its commercially reasonable
     efforts to obtain a protective order or other reliable assurance that
     confidential treatment shall be afforded to such portion of the
     Confidential Information of the disclosing party as is required to be
     disclosed.


                                                                   Page 6 of 114
<PAGE>

(e)  Continuing Obligation.  The obligation of non-disclosure and non-use with
     ---------------------
     respect to Confidential Information of the disclosing party shall survive
     termination of this Agreement and shall continue for a period of 5 years
     thereafter, provided that the obligations of non-disclosure and non-use
     shall continue in perpetuity for software included in Confidential
     Information.

6.   OWNERSHIP AND LICENSE OF WORK PRODUCTS.

(a)  Ownership.  Unless expressly provided otherwise in the applicable Statement
     ---------
     of Work, the ownership of any and all right, title and interest in and to
     work products (including without limitation: computer programs and

     reports; data; information; and other works of authorship) made by Service
     Provider, or its suppliers or contractors, during performance of Services

     Services Agreement relating to ownership of intellectual property, with
     those terms and conditions being applied to any Statement of Work issued
     hereunder and being incorporated herein in their entirety by this
     reference.

(b)  License.  Unless expressly provided otherwise in the applicable Statement
     -------
     of Work:

          (1)  If Service Provider owns any Work Products, any license granted
               to Service Recipient by Service Provider in or to any such Work
               Products shall be on the same terms and conditions as the license
               grant by GTE to GENUITY contained in the Software License
               Agreement, with such terms and conditions being incorporated
               herein in their entirety by this reference.

          (2)  If Service Recipient owns any Work Products, and subject to
               Service Provider's obligations with respect to Service
               Recipient's Confidential Information, Service Provider shall
               retain a non-exclusive, perpetual, world-wide, royalty-free
               license to use any such Work Product for its ordinary and usual
               business purposes.


7.   DISPUTE RESOLUTION.

(a)  General.  Except as provided in subparagraph 7(d) below, any controversy or
     -------
     claim arising out of or relating to this Agreement, or the



                                                                   Page 7 of 114
<PAGE>

     breach thereof, shall attempt to 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.

(b)  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.

(c)  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 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



                                                                   Page 8 of 114
<PAGE>

     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.

(d)  Injunctive Relief.  The foregoing notwithstanding, each party shall have
     -----------------
     the right to seek injunctive relief in an applicable court of law or equity
     independent of any resolution of the dispute in accordance with the
     foregoing.

8.   RELATIONSHIP OF PARTIES.

(a)  Independent Contractors.  In providing any Services pursuant to this
     -----------------------
     Agreement, GTE and its affiliates are independent contractors and not
     agents or representatives of GENUITY.  Persons furnished by the respective
     parties shall be solely the employees or agents of such parties,
     respectively, and shall be under the sole and exclusive direction and
     control of such parties.  They shall not be considered employees of the
     other party or parties for any purpose.  Each party shall also be
     responsible, respectively, for payment of taxes, including federal, state,
     and municipal taxes, chargeable or assessed with respect to its employees
     or agents, such as social security, unemployment, worker's compensation,
     disability insurance and federal and state income tax withholding.

(b)  No Performance.  Neither party undertakes by this Agreement or any
     --------------
     Statement of Work to conduct the business or operations of the other party.
     Nothing contained in this Agreement or any Statement of Work is intended to
     give rise to a partnership or joint venture between the parties or to
     impose upon the parties any of the duties or responsibilities of partners
     or joint venturers.

9.   FORCE MAJEURE.

     If performance of any Services under this Agreement 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



                                                                   Page 9 of 114

     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 commercially 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.

     If a force majeure condition continues to prevent a party from performing
     for more than (30) consecutive days, then the other party may terminate the
     applicable Statement of Work.

10.  REGULATORY COMPLIANCE.

(a)  Cooperation.  This Agreement is subject at all times to any 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 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 by a regulatory agency so that the benefits of this Agreement may
     be achieved.

(b)  Filing Agreement.  Notwithstanding the effective date and term of this
     ----------------
     Agreement as stated elsewhere, to the extent that any statute, order, rule
     or regulation or any regulatory agency having competent jurisdiction over
     one or both parties to this Agreement, shall require that this Agreement or
     subsequent amendment be filed with or approved by such regulatory agency
     before the Agreement or amendment may be effective, this Agreement or
     amendment shall not be effective in such jurisdiction until the first
     business day after such approval or filing shall have occurred.

11.  INDEMNIFICATION.

(a)  General.  GTE and GENUITY, to the fullest extent permitted by law, each
     -------
     shall defend, indemnify and hold harmless the other and its affiliates,
     officers, agents and employees from any and all amounts payable under any
     judgment, verdict, court order or settlement (and associated fees and
     disbursements of counsel) arising from or related to any third-party claims
     for injury, sickness, disease or death of any person or damage to any real
     or tangible personal property or assets to the extent arising from the
     indemnitor's (either directly or through its officers, agents,
     subcontractors or representatives) negligence or willful misconduct in the



                                                                  Page 10 of 114
<PAGE>

     performance of this Agreement provided, however, that if a claim is the
     result of the joint negligence or joint willful misconduct of GTE and
     GENUITY, the amount of the claim for which each party is entitled to
     indemnification shall be limited to that portion of such claim that is
     attributable to the negligence or willful misconduct of the indemnifying
     party. The parties agree that the price for Services provided under this
     Agreement includes consideration for the obligation to indemnify as set out
     in this Section.

(b)  Losses.  GENUITY and GTE each shall be responsible for any and all claims,
     ------
     actions, damages, liabilities, costs and expenses, including reasonable
     attorneys' fees and expenses (collectively, "Losses"), to their respective
     tangible personal or real property (whether owned or leased), and each
     party agrees to look only to its own insuring arrangements (if any) with
     respect to such Losses. Subject to the procedures set forth below, each
     party shall indemnify, defend, and hold the other party harmless from any
     and all Losses arising out of, under or in connection with claims for which
     the indemnitor is responsible under the preceding sentence.

(c)  Waivers.  GENUITY and GTE waive all rights to recover against each other
     -------
     for any Loss to their respective tangible personal property (whether owned
     or leased) from any cause covered by insurance maintained by each of them,
     including their respective deductibles or self-insured retentions.  GENUITY
     and GTE shall cause their respective insurers to issue appropriate waivers
     of subrogation rights endorsements to all property insurance policies
     maintained by each Party.  Each Party shall give the other written notice
     if a waiver of subrogation is unobtainable or obtainable only at additional
     expense.  If the Party receiving such notice agrees to reimburse the other
     Party for such additional expense, the other Party shall obtain such waiver
     of subrogation.  If a waiver is unobtainable or if a Party elects not to
     pay the additional expense of a waiver, then neither Party nor their
     insurers shall waive such subrogation rights.

(d)  Defense.  Except as otherwise set forth in the applicable Statement of
     -------
     Work, and subject to the limitations and procedures set forth below, GTE
     agrees to defend GENUITY against any action to the extent that such action
     is based upon a claim that the Service provided by GTE pursuant to this
     Agreement (i) infringes a United States copyright, (ii) infringes a United
     States patent or (iii) constitutes an unlawful disclosure, use or
     misappropriation of another party's trade secret and not as the result of
     any prohibited use or transfer by GENUITY.  GTE shall bear the expense of
     such defense and pay any Losses finally



                                                                  Page 11 of 114
<PAGE>

     awarded by a court of competent jurisdiction that are directly attributable
     to such claim.

(e)  Contributory Infringement.  GTE shall not be liable to GENUITY for claims
     -------------------------
     of indirect or contributory infringement.  Further, GTE shall have no
     liability to GENUITY hereunder if (i) the claim of infringement is based
     upon the use of Services or Work Products 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 Services or Work Products are used outside of the scope of
     the rights and licenses granted to GENUITY; (iii) the Services or Work
     Products are modified by or for GENUITY (including by GTE at GENUITY's
     direction or instructions), and such infringement would not have occurred
     but for such modification; (iii) GENUITY uses any of the Services or Work
     Products in the practice of a patented process and there would be no
     infringement in the absence of such practice, or (iv) the claim of
     infringement arises out of the GTE's compliance with written directions
     provided by GENUITY and such infringement would not have occurred but for
     such compliance.  For all of the foregoing exclusions, GENUITY shall defend
     and indemnify GTE for any infringement claims to the extent set forth in
     Section 11(d).

(f)  Mitigation.  If a Service or Work Product 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 as required above, GTE may, at its option and
     in its sole discretion, and at its own cost and expense: (i) replace or
     modify such Service or Work Product 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 Service or Work Product pursuant to this
     Agreement; or if neither (i) nor (ii) are possible at a commercially
     reasonable cost, (iii) require the return of such Service or Work Product,
     terminate the Statement of Work (to the extent it has not yet been
     completed) and terminate GENUITY's right to use the same and refund to
     GENUITY a pro-rata portion of the amount actually paid to GTE by GENUITY
     for such Service or Work Product.  Notwithstanding the foregoing, if GTE
     exercises its right to require the return of such Service or Work Product
     and terminates GENUITY's right to use the same, to the extent permitted by
     applicable law, GENUITY may retain and continue to use such Service Work
     Product 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



                                                                  Page 12 of 114
<PAGE>

     Service or Work Product. The foregoing sets forth GTE's sole and exclusive
     obligations, and GENUITY's sole remedies, for infringement of intellectual
     property by Services or Work Product.

(g)  Conditions.  The indemnification obligations set forth in this Section
     ----------
     shall not apply unless the party claiming indemnification:  (i) notifies
     the other promptly in writing of any matters in respect of which the
     indemnity may apply and of which the notifying party has knowledge, in
     order to allow the indemnitor the opportunity to investigate and defend the
     matter; provided, however, that the failure to so notify shall only relieve
     the indemnitor of its obligations under this Section if and to the extent
     that the indemnitor is prejudiced thereby; and (ii) gives the other party
     full control of the response thereto and the defense thereof, including any
     agreement relating to the settlement thereof.  However, if the indemnitor
     fails to promptly assume the defense of the claim, the party entitled to
     indemnification may assume the defense at the indemnitor's cost and
     expense.  The indemnitor shall not be responsible for any settlement or
     compromise made without its prior written consent, unless the indemnitee
     has tendered notice and the indemnitor has then refused to assume and
     defend the claim and it is later determined that the indemnitor was
     obligated to assume and defend the claim.  The indemnitee agrees to
     cooperate in good faith with the indemnitor at the request and expense of
     the indemnitor.

12.  LIMITATION OF LIABILITY.

(a)  General.  A party's and its affiliates' liability arising out of or
     -------
     relating to a Statement or Statements of Work and this Agreement, including
     without limitation on account of performance or nonperformance of
     obligations hereunder, regardless of the form of the cause of action,
     whether in contract, tort (including without limitation negligence),
     statute or otherwise, shall in no event exceed the lesser of (i) the price
     to be paid to GTE for the completed Statement of Work (whether set out as a
     fixed price, estimated price, not-to-exceed amount, or other similar
     expression of the total price for the work to be performed under the
     Statement of Work); or (ii) the amount actually paid by GENUITY to GTE for
     the particular Statement of Work from which the claim arises. The
     limitation in the immediately preceding sentence does not apply to a
     party's obligations under the Sections entitled Indemnification and
     Confidential Information, nor does it apply to willful misconduct or gross
     negligence on the part of a party.

(b)  Limitation.  EXCEPT FOR BREACHES RELATED TO CONFIDENTIAL INFORMATION,
     ----------
     NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY INDIRECT, INCIDENTAL,
     PUNITIVE, EXEMPLARY, SPECIAL



                                                                  Page 13 of 114
<PAGE>

     OR CONSEQUENTIAL DAMAGE OR LOST PROFITS OF ANY KIND WHATSOEVER EVEN IF A
     PARTY OR ITS AFFILIATES HAVE BEEN APPRISED OF THE LIKELIHOOD OF SUCH
     DAMAGES OCCURRING.

(c)  Benefits Under Licenses.  Anything contained herein to the contrary
     -----------------------
     notwithstanding, this Agreement shall not constitute an agreement to start
     work, to provide Services or Work Product or to make available to GENUITY
     the benefits under any agreement, license or arrangement if doing so
     without the consent of and/or payment to another party thereto would
     constitute a breach thereof or in any material way affect the rights of GTE
     thereunder, unless and until such consent is obtained and payment, if any,
     made to such party by GTE, provided however, that GTE will use commercially
     reasonable efforts to secure such consents and benefits under any such
     agreement or arrangement.  If GTE cannot: (i) obtain such consent; or (ii)
     GTE and the third party vendor cannot agree on a commercially reasonable
     payment, if such is required, or (iii) if providing the Services or Work
     Products or making the benefits under any such agreement, license or
     arrangement available would materially affect GTE's rights thereunder, GTE
     shall not be required to provide any Services or Work Products which are
     dependent upon such agreement, license or arrangement. GENUITY may,
     however, obtain the requisite license or rights, or pay such fees necessary
     for GTE to provide the Services.

13.  CHANGES IN MANNER OF PROVIDING SERVICES.

     GENUITY acknowledges that GTE and its affiliates may in the future
     determine to outsource certain information technology functions or perform
     such functions using different computer software operating systems or
     applications.  These changes may prevent GTE from providing certain
     Services or Work Products to GENUITY pursuant to this Agreement in the
     manner in which they have been provided prior to such change.  In the event
     GTE determines to take any such action, it will provide GENUITY with one
     hundred twenty (120) days prior written notice and will cooperate with
     GENUITY to enable GENUITY to continue to receive any affected Services and
     Work Products through arrangements with GTE's outsource providers or
     through conversion of GENUITY data for use on such operating systems or
     applications.  In the event GTE determines to make such changes, GENUITY
     shall have the right to terminate this Agreement or any affected STATEMENT
     OF WORK without any liability or penalty. Any customizations requested by
     GENUITY within or to the systems utilized by GTE to provide the Services
     shall be at GTE's discretion. GENUITY shall be required to pay the mutually
     agreed upon cost of such customizations.



                                                                  Page 14 of 114

14.  INSURANCE.

     --------
     of this Agreement, and so long as the indemnity obligations hereunder are
     in effect, for GTE the following minimum insurance coverages:  (i) Worker's
     Compensation and Occupational Disease covering GTE's full liability under
     the Statutory Workers' Compensation Laws for the state in which the Service
     is being performed; (ii) Employer's Liability Insurance in the minimum

     vehicles is required, comprehensive Motor Vehicle Liability Insurance to
     include, but not limited to owned, non-owned, leased, and hired vehicles in
     the minimum amounts of $1,000,000 combined single limit per occurrence for
     Property Damage and any accident resulting in bodily injury or the death of
     one or more persons, and the consequential damages arising therefrom.

(b)  Certificates of Insurance.  Certificates of Insurance, incorporating the
     -------------------------
     above-described endorsements, shall be furnished to GENUITY upon request.

15.  REPRESENTATIONS AND WARRANTIES.

     GTE represents, warrants, and covenants to GENUITY that:

     assignable by either of the parties hereto; provided that GTE may delegate
     all or any portion of its obligations to perform Services under this

     any affiliate without the consent of the other party.

(b)  GTE may use subcontractors to perform the Services under this Agreement as

     system of the other party in order to accomplish the Services called for in
     this Agreement, the party that receives such access shall limit such access
     and use solely to perform Services within the scope of this Agreement and
     shall not access or attempt to access any computer system, electronic file,
     software or other electronic services other than those specifically
     required to accomplish the Services required under this Agreement.  Under
     no circumstances shall either party's  personnel access any  networks or
     facilities of the other party for the purpose of accessing other external
     networks, nor shall any such capabilities for such access be published or
     made known via any medium, as for example and not by way of limitation,
     posting on bulletin boards or E-mail.  Any such use or publication shall be
     a material breach of this Agreement.  Neither party shall use back doors,
     data capture routines, games, viruses, worms, or Trojan horses and any
     intentional introduction of such into the other party's data networks shall

     cooperate with the other in the investigation of any apparent
     unauthorized access to a party's computer or electronic data storage
     systems.

20.  GENUITY RESPONSIBILITIES.

     GENUITY agrees to perform in a timely fashion those tasks, and to provide
     the personnel, facilities and accurate information as agreed by the
     parties and set forth in the applicable Statement of Work. GENUITY
     further agrees to cooperate with GTE in its performance of this
     Agreement, to not unreasonably withhold its consent to any matter for
     which consent is required or requested.

21.  PERMITS.

     Unless otherwise specifically provided for in this Agreement, GTE shall

3.  (GTE Account Manager) is the Genuity point of contact for all contractual
    matters related to this SOW. Any requests for any changes to tasks or new
    functionality should be forwarded in writing to (GTE Account Manager).

4.  The estimates outlined in this SOW assume support for 3,800 Genuity
    employees. If this number increases, the resources assigned to support
    Genuity would need to be reassessed.

5.  It is expected that there will be several changes to the work outlined
    within these SOWs over the next several weeks as benefit plans and other
    specific Genuity processes become finalized. A key point to remember is that
    these types of changes cannot be implemented overnight.

6.  Maintenance tasks within this SOW are for minor Business As Usual (BAU)
    tasks in support of production. If there are any BAU changes/modifications
    beyond minor maintenance, such as mass re-organizations, benefit plan
    changes, new functionality, etc., these changes/modifications will be
    incorporated into a new development SOW. Specific tasks, prices and
    schedules would be developed for the agreed upon SOW.

7.  Genuity agrees to review HR audit reports and act upon any errors identified
    in a timely manner to ensure data integrity within the system and with
    downstream vendors.

8.  Upgrades/Enhancements: For any systems where a common development
    environment exists, e.g., SAP, Employee Data Warehouse (EDW), Quincy
    Processing Center (QPC) systems, agrees to abide by the standards, changes,


                                                                  Page 53 of 114
<PAGE>

    upgrades, and enhancements that have been, or will be, developed and
    implemented across the environment. A proportion of the on-going development
    tasks will be apportioned to Genuity in the same manner as production costs
    as allocated. Examples include Employee Self Service (ESS) enhancements,
    Manager's Desktop, On-line Org Charts. Genuity will participate in a user
    forum to assist in prioritizing these enhancements.

    Should Genuity desire to not abide by, and share appropriate costs for, the
    baseline system configuration and associated upgrades and enhancements, a
    completely separate physical environment for Genuity would be warranted. GTE
    would be pleased to develop a technical and cost proposal for such work at
    the request of Genuity.

9.  This SOW highlights both production tasks and one-time development tasks
    that must also be performed to set up or establish the systems environment
    for Genuity.

conditions thereof. The services described herein shall be provided during the

                                  Schedule B
                     Billing Services Performance Measures


CSI and GENUITY agree to jointly define and establish a detailed action plan to
develop metrics that measure the effectiveness of the overall billing process
and compliance with the Billing Services business policies and procedures
established by GENUITY ("Action Plan") within sixty (60) days following the
effective date of this agreement. The Action Plan, will provide a mechanism to
establish guidelines ("Guidelines")based on performance metrics agreed upon by
the parties in accordance with the SOW and Transition Agreement. The Guidelines
will become effective upon the effective date of the renewal term, if any.
Included in the operating metrics will be measurements associated with the
services performed by CSI, as described in Schedule A-Description of Services,
as well as measures associated with the functions performed by GENUITY which are
an integral part of the total billing process, including but not limited to
usage polling and collection and provisioning timeliness.

Operating and compliance metrics will be defined and established relating to
billing timeliness and accuracy and credit and collections performance. CSI and
GENUITY agree to use the initial term of this agreement to establish threshold
levels of performance by CSI related to the metrics identified, and to establish
remedies to address CSI's inability to meet such performance levels in future
terms. The parties agree that assessment of actual performance against agreed
upon threshold levels, as well as implementation of the foregoing remedy
structure will begin in the renewal term, if any, of this agreement.

The Metrics established will be in substantially the form attached hereto.
Performance will be measured on a monthly basis, from the 1/st/ through the
31/st/. Metrics will exclude any jointly agreed upon holidays during which the
defined billing services may not be performed. Any variance from these
performance measures will be described in writing with actions identified to
bring performance to the agreed upon level.

                                  Schedule D
                           Change Request Procedures


1.0    Change request procedures to modify CSI's billing system or subprocess
   support systems are initiated through a written Change Request  (CR).

2.0    A high level estimate of the Time and Cost (T&C) for changes the CSI
   systems or processes (order of magnitude) may be requested through the CHANGE
   REQUEST process. An order of magnitude may also be requested at the early
   stages of product or service development (INTERNETWORKING's PDMM or PD&L
   processes) to project anticipated costs and roll-out schedules. Order of
   magnitude estimates are not binding and will be estimated at CSI's
   discretion. Should INTERNETWORKING wish to pursue implementation of the
   change proposed in the order of magnitude, INTERNETWORKING shall issue a
   formal request for a T&C estimate as outlined in Section 3.0.

3.0INTERNETWORKING may request a T&C estimate by submitting a T&C CHANGE REQUEST
   form to CSI's Change Control Manager. CSI will normally respond to
   INTERNETWORKING's request for an estimate within five (5) Business Days of
   receipt for table changes, ten (10) Business Days for pricing or contract
   changes and thirty (30) Business Days for new development. CSI's response
   will include the cost for development and implementation activities, an
   estimate of any new recurring charges, the implementation date, and all
   assumptions and/or deviations from INTERNETWORKING's specifications. This
   shall be a binding commitment from CSI to deliver the requested functionality
   at the stated price and on the stated date except as noted in Section 11.0 of
   this Attachment. For complex requests for new development a detailed break-
   out of the cost by functionality may be requested by INTERNETWORKING.

       3.1  All T&C CHANGE REQUEST responses shall include a listing of any new
            or increased recurring billing functional or data processing charges
            that shall apply. All recurring charges will require written
            authorization by INTERNETWORKING prior to development and
            implementation of the T&C CHANGE REQUEST.

       3.2  In the event this information is unavailable on the day the T&C
            CHANGE REQUEST quote is rendered to INTERNETWORKING, CSI will state
            in the quote that the recurring rate will be provided at a later
            date or a date to be negotiated between the Parties.

       3.3  If a request is considered by CSI to be too complex to meet the
            specified time requirement, or the information contained in the
            request is deemed insufficient, CSI shall notify INTERNETWORKING
            within
<PAGE>

          fifteen (15) Business Days of receipt of original request and
          the Parties shall negotiate a new response date for CSI's T&C CHANGE
          REQUEST quote.

     3.4  Upon agreement on the cost and implementation dates, the originator of
          the T&C CHANGE REQUEST or INTERNETWORKING's executive management will
          issue to CSI a formal authorization, in writing, authorizing the
          entire quote or option selected, if applicable. In the event that such
          authorization is received via e-mail or Internet, INTERNETWORKING
          hereby releases CSI from any and all liability to confirm the
          authenticity of the authorizing party or to otherwise validate the
          authority of the record's originator to authorize CSI to proceed with
          the development work.

4.0 INTERNETWORKING shall respond to CSI's requests for clarification of a
    change request or for requests for additional information in a timely
    manner. During the time period that questions pertaining to pending change
    request are outstanding, the T&C CHANGE REQUEST will be considered on hold
    by CSI. Once all questions are completely satisfied by the Parties, the
    project status will change to "Active/in Progress." Any delays in receipt of
    clarification or additional information requested may impact the delivery
    date of CSI's response and/or implementation date. CSI will advise the
    originator of the order regarding these delays.

5.0 INTERNETWORKING may issue a T&C CHANGE REQUEST to CSI to immediately
    commence work on the project by preauthorizing a portion of the total cost
    of the project.

     5.1  Once the entire quote has been issued by CSI, INTERNETWORKING must
          respond within ten (10) Business Days to authorize CSI to continue and
          complete the project. If full authorization has not been received, CSI
          may cease further project development when the preauthorized funded
          amount has been exhausted.

     5.2  If CSI ceases development of a T&C CHANGE REQUEST due to a delay in
          obtaining INTERNETWORKING's authorization or clarifications, the
          quoted costs and implementation date may be impacted.

6.0 All communications with INTERNETWORKING (written or oral) will be
    coordinated through the originator of the change request. All changes to
    the specifications of the requirement or interpretation of the
    specifications shall be in writing. INTERNETWORKING shall make available to
    CSI for each T&C CHANGE REQUEST an individual knowledgeable in all aspects
    of the


                                       2
<PAGE>

     CHANCE REQUEST with whom the assigned CSI counterpart may discuss project
     design and details in depth.

7.0  INTERNETWORKING shall notify CSI within ten (10) Business Days of the date
     of the T&C CHANGE REQUEST estimate whether the proposed estimate is
     accepted or rejected. The CHANGE REQUEST will be automatically rejected
     upon the expiration of ten (10) Business Days and no further communication
     is required for a rejected estimate. Where INTERNETWORKING is unable to
     meet the ten (10) Business Day requirement, INTERNETWORKING will notify CSI
     and the Parties will agree upon a new date. If INTERNETWORKING fails to
     notify CSI within twenty (20) Business Days of the acceptance or rejection
     of the T&C CHANGE REQUEST estimate, the estimate will be null and void and
     the T&C CHANGE REQUEST shall be considered void and CSI will notify
     INTERNETWORKING in writing of the canceled status.

8.0  INTERNETWORKING has the right to request a reconsideration when the T&C
     CHANGE REQUEST estimate from CSI that does not meet INTERNETWORKING's
     requirements or expectations. INTERNETWORKING shall notify CSI within ten
     (10) Business Days that a reconsideration is necessary. CSI agrees to
     discuss the basis for the estimate with INTERNETWORKING.

9.0  Any new recurring charges must be approved by INTERNETWORKING and by CSI
     and shall be included in the Agreement via a written amendment.

10.0 If INTERNETWORKING cancels an authorized or preauthorized request after
     receipt by CSI, INTERNETWORKING shall compensate CSI for all work completed
     prior to cancellation and for any efforts required to remove system
     functionality from code libraries. Within thirty (30) Business Days
     following notification of cancellation, CSI will send written notice to
     INTERNETWORKING regarding the amount owed by INTERNETWORKING, which shall
     be due upon receipt of such notice by INTERNETWORKING.

11.0 For T&C CHANGE REQUEST changes, unless otherwise agreed, CSI shall complete
     implementation by the agreed upon date stated in the quote. CSI shall use
     reasonable efforts to notify INTERNETWORKING if the scheduled
     implementation date will be in jeopardy. If an agreed upon implementation
     date is missed, CSI shall orally notify INTERNETWORKING as soon as
     possible. CSI shall provide written notification to INTERNETWORKING of its
     new implementation date within five (5) Business Days.

12.0 If following CSI's commitment pursuant to Section 3.0, requested
     functionality is not correctly implemented, by the agreed upon date, and
     has

                                       3
<PAGE>

      affected INTERNETWORKING's Customer's' bills, INTERNETWORKING's sole
      remedy shall be as follows:

12.1  CSI will make credit adjustments to the Customer's bills if required

      If the cause of the incorrect functionality is due to incomplete or
      inaccurate requirements by INTERNETWORKING or from INTERNETWORKING's sign
      off on incomplete or inaccurate requirements or test results, CSI will not
      be held responsible for incorrect bills issued to customers.
      INTERNETWORKING will be responsible for any additional costs necessary for
      correcting the incaccuracies.

13.0  INTERNETWORKING will provide in the initial T&C CHANGE REQUEST user
      acceptance test criteria that will be used by CSI during user acceptance
      testing and will specify if a test bill is required prior to implementing
      the changes. If requested, and provided that INTERNETWORKING has
      authorized or preauthorized development, CSI will use reasonable efforts
      to provide a test bill sample to INTERNETWORKING. INTERNETWORKING agrees
      to validate the accuracy of the requested changes and provide concurrence
      to CSI in writing within five (5) Business Days or prior to the first mail
      date if less than five (5) days. INTERNETWORKING shall hold CSI harmless
      from any liability for billing errors that may result from the requested
      changes.

14.0  INTERNETWORKING will note in the initial T&C CHANGE REQUEST if a post
      implementation bill sample is required.

15.0  CSI shall notify INTERNETWORKING within ten (10) Business Days after
      implementation that all work has been completed or procedures are in
      place.

CSI shall begin to bill INTERNETWORKING at the time the estimate is authorized
and development work has begun. The payment schedule will be based upon work
incurred in a given month. Notwithstanding the foregoing, CSI shall have the
option, based on a credit review of INTERNETWORKING or CSI policies and
procedures, to require prepayment of CHANGE REQUE

                                  Schedule E
                               ARBOR Conversion


At the time of this agreement CSI and INTERNETWORKING are jointly involved in
converting from INTERNETWORKING's Oracle Billing platform to CSI's Kenan ARBOR
billing platform ("Arbor Platform"). INTERNETWORKING AND CSI agree that this
project is of strategic importance to INTERNETWORKING and commit to completion
of this project as outlined in this Schedule E.

Overall funding for this conversion is the responsibility of CSI and the overall
conversion project ("Conversion Project") will be managed by CSI. A detailed
implementation plan exists to migrate INTERNETWORKING current customer base from
Oracle to the Arbor Platform, develop new usage based mediation and rating
processes, and to write the business rules in support of INTERNETWORKING
products and services to be billed by CSI from the ARBOR Platform. The Arbor
Conversion project will go to production in the third quarter 2000 and will be
complete by 12/12/2000 when post Arbor Conversion activities are completed.

The project plan requires INTERNETWORKING resources, cooperation and support to
accomplish the Arbor Conversion and the parties will each contribute personnel
to accomplish the Arbor Conversion ("Conversion Team") Arbor Conversion
activities of the parties will include but are not limited to:

INTERNETWORKING will:

1. work with CSI First Rate team to ensure the various data collectors will pass
   the required usage data to First Rate for mediation to ARBOR.

2. work with the CSI Conversion Team to provide the necessary customer data from
   the Oracle legacy system to be migrated to ARBOR.

3. provide a full time representative to the Conversion Team.

4. will continue to participate on the Conversion Team to ensure that the
   Conversion Team is current on all changes implemented in the interim.

5. INTERNETWORKING Data Control will continue to participate on the Conversion
   Team to ensure all price book changes are communicated to the Conversion
   Team.

                                       1
<PAGE>

CSI will :

1. work with INTERNETWORKING to provide a detailed migration approach and plan
   that encompasses all required tasks to complete the Oracle Financials to
   Arbor conversion as it pertains to usage mediation and billing.

2. work with INTERNETWORKING to model all products within the Arbor 9.1 Billing
   instance to meet the previously defined requirements.

3. work with INTERNETWORKING to develop an end-to-end set of test criteria and
   scripts to perform a comprehensive test of the conversion and ensure billing
   accuracy once conversion occurs.

4. design, develop, and provide all required interfaces to handle usage
   mediation, general ledger, bill distribution, bill formatting, taxing,
   commissions, compensation, data warehouse, reseller billing, payments, and
   collections.

5. continue to work with INTERNETWORKING to develop all processes, teams, and
   practices required to provide the core billing functions of data
   accumulation, bill processing, bill format and distribution, inquiry and
   investigation, credit verification, collections, and payment processing
   evolving out of this conversion.

There may be other activities identified as the Conversion Team moves through
the project. INTERNETWORKING will support these activities as identified.

The Arbor Conversion Project plan calls for the Oracle/bp databases to be
available through 2003, as historical data contained in these databases will not
be converted.  CSI may require access to the Oracle/bp database history for
resolution of billing inquiries and referrals.  INTERNETWORKING agrees to
maintain and support the Oracle/bp historical databases thorough year-end 2003.

CSI will manage the ARBOR Conversion Project per the current schedule and will
engage other resources or affiliates as necessary. Status reporting will
continue as it exists today, as will the Core Team and the Executive Team.
INTERNETWORKING, INTERNETWORKING AND CSI commit to continued executive
representation on these teams.

of new products and services, utilizing the "GTE" tax billing matrix as the
primary source ("Tax Services"). The Tax Billing Matrix will be the long-term
solution as the vehicle used to determine the tax rates of products and

within the term of the Billing and Collection SOW. The "GTE" Tax Department will
provide updates, changes, and corrections as required to the Tax Billing Matrix.
The interim method of communicating taxation rates of products and services will
be via email between CSI, INTERNETWORKING and GTE Tax Department.

Not included as a part of this Tax Billing Matrix services are: contract
reviews, projects such as nexus requirements, prototype design interaction,
products/services rollout implementation process, etc.

Change Control
- --------------

The introduction of new products and services will be incorporated with the
product standardization process with direct interaction from INTERNETWORKING
product managers.

The update of tax rates will continue to be handled by CSI.

System Testing
- --------------

System Testing includes auditing tables and functionality requirements for
existing and future INTERNETWORKING companies. In addition, report writing
functionality will be tested as required for tax compliance and other ad-hoc
reports.

          and statements of work ("Statements of Work") entered into by the

          collectively referred to as the "Agreement"), and Service Provider
          shall provide to Service Recipient such information technology
          transitional services (individually and collectively, "Services"). If
          there is any conflict or inconsistency between the terms and
          conditions of a Statement of Work and the terms and conditions of this
          Agreement (excluding for this purpose the Statements of Work), the
          terms and conditions of the Statement of Work shall control.

          to the Services to be performed and the obligations of the parties. If
          there is any conflict or inconsistency between the terms and

          Agreement (excluding for this purpose the Statement of Work), the
          terms and conditions of the Statement of Work shall control. Service
          Recipient may request services through a letter, email, or other
          written or electronic medium. The request for services will outline
          the nature and scope of the services requested. Within thirty (30)
          days after receipt of the request for services, Service Provider shall
          provide a high-level estimate of the activities to be performed along
          with an estimate of the number of hours required to perform each of
          the activities. Preparation of the high level estimate shall be
          charged at the hourly rates then in effect between Service Provider
          and Service Recipient, or if no rate is specified, at Service
          Provider's then-current rate for such activity. Service Recipient
          shall have thirty (30) days to notify Service Provider if Service
          Recipient desires Service Provider to prepare a Statement of Work.

          Statement of Work shall be issued on a time and materials basis and

          requires travel to Service Recipient's location or another location at
          the request of Service Recipient, Service Provider shall bill travel
          time incurred by Service Provider's employees at the hourly rate(s)
          specified in the Statement of Work. Service Provider shall issue an
          invoice monthly for such services in accordance with this Agreement.

          Provider hereunder, the terms and conditions contained in Attachments

               Work);

          such milestones and the Statement of Work shall be deemed to be
          modified accordingly. The Statement of Work may be modified by mutual
          written agreement, signed by both parties. No verbal changes to the
          Statement of Work are permitted.

     (e)  Performance.  All Services shall be performed in accordance with the
          terms and conditions of this Agreement and the requirements, order of
          performance and delivery dates specified in each Statement of Work.
          Service Provider shall devote such time, efforts and resources to the
          performance of Services as are necessary to accomplish the tasks
          specified in any Statement of Work. The Service Provider may call upon
          the expertise and/or assistance of its affiliates, subcontractors or
          consultants in the performance of such Services, provided that Service
          Provider shall obtain the prior written consent of Service Recipient
          in the event it desires to use outside subcontractors or consultants.
          If a

                                       3

          Statement of Work specifies that some or all of the work will be
          done by a subcontractors or consultant, no additional approval shall
          be required.

     (f)  Third Party Software Licenses.  The Service Recipient acknowledges
          that Service Provider and its affiliates may be required to use
          certain software licensed to GTE by third parties to provide Services
          pursuant to this Agreement. If any licensor of such third party
          software requires the payment of any consideration to permit Service
          Provider to use the vendor's software in order to perform its
          obligations under this Agreement, Service Provider shall provide
          Service Recipient with thirty (30) days prior written notice of such
          additional consideration. Service Recipient shall have the option to
          (i) procure its own license to such software at its own expense, or
          (ii) authorize Service Provider to incur such required additional
          consideration on its behalf and at Service Recipient's expense. In the
          event that Service Recipient does not agree to either (i) or (ii)
          above, Service Provider shall not be required to provide the Services
          for which such third party licenses are required. If the third party
          requires Service Recipient to secure rights in such third party
          software to receive the Services or to use the result of such
          Services, Service Recipient shall be responsible for securing such
          rights at its own cost and expense.

     (g)  Service Recipient Provided Software.  If Service Recipient elects to
          use Service Provider Hardware (as defined below) to operate and run
          Service Recipient Provided Software (also as defined below) pursuant
          to a Statement of Work, Service Recipient shall obtain all licenses
          necessary for use of such software, pay any associated fees negotiated
          with Service Provider for running such software for Service Recipient
          and pay any costs related to obtaining required consents needed by
          Service Provider to use such software for Service Recipient's benefit.
          Service Recipient shall be responsible for all costs associated with
          Service Recipient provided third party software. Service Recipient
          agrees to indemnify and hold Service Provider harmless against any
          loss, cost, claim, liability, damage, expense (including reasonable
          attorney's fees), or demand by or on behalf of any person, firm,
          corporation, or governmental authority resulting from or arising out
          of Service Recipient's alleged violation of such third party software
          rights, provided that prior to agreement on a Statement of Work, the
          parties shall have worked diligently together to identify all license
          rights needed by Service Recipient hereunder and to confirm that
          Service Provider has the right to perform the services hereunder.
          "Service Provider Hardware" shall mean the central processing units
          and peripheral equipment installed in a Service Provider's facility
          and utilized by Service Provider to provide Services described in any
          Statement of Work. The term Service Provider Hardware does not include
          circuit equipment from Service Recipient's site to Service

                                       4

<PAGE>

          Provider's facility, terminals, controllers, or telecommunications
          equipment at Service Recipient's site(s) required to enable Service
          Recipient to utilize Service Provider's Services, all of which are
          Service Recipient's responsibility. "Service Recipient Provided
          Software" shall mean software owned or licensed by Service Recipient
          which is installed an operated at a Service Provider facility pursuant
          to a Statement of Work.

2.   COMPENSATION AND BILLING.

     (a)  Invoices.  The charges for the Services shall be set out in the
          applicable Statement of Work. Service Provider shall invoice Service
          Recipient for Services in accordance with the payment schedule set
          forth in the applicable Statement of Work. Each invoice shall
          reference this Agreement and the applicable Statement of Work. The
          invoices shall be itemized to show the details as to all billed items.
          Payments shall be made within thirty (30) days from the date each
          invoice is received by Service Recipient.

     (b)  Sales, Use and Other Taxes.  In addition to the charges for Services,
          Service Recipient shall pay Service Provider 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 with
          respect to the Services lawfully levied by a duly constituted
          governmental authority and for which Service Provider is required, by
          law, to collect from Service Recipient. In addition each party shall
          be responsible for all real and personal property taxes imposed on
          software and equipment owned by the respective parties on January 1 of
          every year. If Service Recipient determines that any Services are
          exempt from a tax, Service Recipient must provide Service Provider a
          properly completed exemption certificate, for each jurisdiction for
          which Service Recipient is claiming an exemption, before Service
          Provider will exclude the respective tax from amounts charged to
          Service Recipient. Service Recipient will not deduct any tax amount
          from remittances to Service Provider until a properly completed
          exemption certificate, for all jurisdictions for which Service
          Recipient is claiming an exemption, has been provided to Service
          Provider.

     (c)  Expense Reimbursement. Service Recipient shall reimburse Service
          Provider for reasonable expenses for travel, meals and lodging
          incurred by Service Provider in the performance of its obligations
          under this Agreement. Any such charges shall be in compliance with
          Service Provider's employee expense policies. There shall be no mark-
          up of such expense charges. Service Provider shall maintain
          documentation of expenses incurred, and shall provide copies of
          invoices of $100 or more upon Service Recipient's request. Service
          Provider shall bill Service

                                       5

<PAGE>

          Recipient monthly for expenses as they accrue. The parties will
          specify any limitation on the reimbursement of expenses in the
          applicable Statement of Work. It is acknowledged and agreed that if
          Service Provider is reasonably required to incur expenses beyond such
          limitation in order to provide the Services, then Service Provider is
          excused from performing such Services until said expense limitation is
          removed or changed as mutually agreed, provided that Service Provider
          promptly notifies Service Recipient of the need to exceed the
          limitation.

     (d)  Records.  Service Provider shall maintain complete and accurate
          records in a form consistent with generally accepted accounting
          practices, to substantiate Service Provider charges. Service Provider
          shall retain, and make available upon request, such records for a
          period of three (3) years from the date of invoice for Services.
          Service Recipient and its authorized agents, subject to obligations of
          confidentiality as set forth in this Agreement, shall have access to
          such records upon prior written request during normal business hours
          during the term of this Agreement and during the respective periods in
          which Service Provider is required to maintain such records pursuant
          to this subsection 2(d). Access to the records shall be made at the
          location where such records are normally maintained.

     (e)  Late Payment.  Late payment charges may be imposed by Service Provider
          at the rate of 1 1/2% per month (18%) per year). Interest shall not be
          payable by Service Recipient for amounts on invoices which it has
          disputed in good faith provided that Service Recipient pays the
          applicable amount due, if any, within thirty (30) days of the
          resolution of the dispute. With respect to disputed invoices,
          undisputed amounts must be paid within thirty (30) days from the date
          of the invoice. Service Provider must be advised in writing of any
          amounts disputed by Service Recipient and the basis for the dispute
          within ten (10) days from the date of the invoice or the entire
          invoice must be paid.

3.   TERM.

     This Agreement is effective as of _____________ and shall continue in
     effect for a term of one (1) year, or such term as may be set out in a
     Statement of Work, or until GENUITY exercises its right in its sole
     discretion to terminate for convenience under Section 24 (c) of this
     Agreement. This Agreement shall remain in effect with respect to and for
     the duration of any Statement of Work that is agreed by the parties to
     extend beyond the end of the term.  In the event of any termination or
     expiration, the Parties agree to reasonably cooperate in transitioning the
     work to any successor service provider, and upon Service Recipient's
     request and at its expense, Service Provider shall use commercially

                                       6

<PAGE>

     reasonable efforts to secure Service Recipient's continued use of
     applicable third party licenses.

4.   ACCEPTANCE.

     (a)  Acceptance.  Each Statement of Work shall specify the criteria, if
          any, that Service Provider must meet in order for the Work Products
          described in the Statement of Work to be accepted by Service
          Recipient. It may also specify a test plan, and such other information
          as Service Provider and Service Recipient mutually deem appropriate
          and the period of time, if any, that Service Recipient shall have to
          review such Work Product and provide notice of acceptance or rejection
          to Service Provider. Failure to accept or reject such Work Product
          within the specified period of time or the commercial use of such Work
          Product by or for the benefit of Service Recipient shall be deemed to
          be acceptance.

     (b)  Rejection and Revision.  If Service Recipient rejects any Work
          Product, it shall specify in reasonable detail in writing the reasons
          for rejection and the requirements for revision. If the notice of
          rejection is not sufficiently detailed to allow Service Provider to
          determine why such Work Product is unacceptable, Service Provider may
          request in writing that Service Recipient provide sufficient
          additional information. If Service Provider and Service Recipient have
          joint responsibility for the Work Product and the Work Product
          requires revision, Service Provider shall assist Service Recipient in
          making revisions necessary for the Work Product to meet the acceptance
          criteria within a period of time that is reasonable under the
          circumstances. If Service Provider has sole responsibility for the
          Work Product, then it shall make the necessary revisions within a
          period of time that is reasonable under the circumstances.

5.   CONFIDENTIAL INFORMATION.

     (a)  Confidentiality.  In the course of requesting and performing Services
          pursuant to this Agreement, each party may receive or acquire from the
          other information or data pertaining to specifications, drawings,
          sketches, models, samples, computer programs, methods, concepts, know-
          how, techniques, processes, and other technical or business
          information that the other party desires to protect against
          unauthorized use or further disclosure. Unless otherwise expressly set
          forth in a Statement of Work, for purposes of this Agreement,
          "Confidential Information" shall mean: (i) any information in written,
          other tangible or electronic form which is labeled by the disclosing
          party as "confidential", "proprietary" or with a

          time of such disclosure which is summarized in writing within thirty
          (30) days of such disclosure.  Each party shall remain the exclusive
          owner of its Confidential Information.

     (a)  Use of Confidential Information. The Confidential Information of the
          disclosing party may be used by the receiving party only for the
          performance or use of Services or Work Products to be provided
          pursuant to this Agreement and may only be disclosed to those
          employees, subcontractors or agents of the receiving party who have a
          need to know in order to perform or use Services or Work Products
          pursuant to this Agreement. Except and to the extent set forth in
          subsection 6(c), the receiving party may not disclose Confidential
          Information of the other party to any other person, entity, or the
          public without the prior written consent of the disclosing party.
          However, such Confidential Information may be disclosed by the
          receiving party without the necessity of prior written consent, to the
          receiving party's subcontractors or consultants who require access to
          such Confidential Information to perform or use the Services under
          this Agreement, provided such persons have entered into written
          agreements which contain obligations of nondisclosure and nonuse no
          less restrictive than set forth in this Section 6. It is agreed that
          such written agreements shall be enforceable by the disclosing party.

     (b)  Exceptions.  The obligations in subsection 6(b) shall not apply to
          that portion of any information received from the disclosing party
          which is: lawfully in the receiving party's possession, with no
          restriction on use or disclosure, prior to its acquisition from the
          disclosing party; received in good faith by the receiving party, with
          no restrictions on use or disclosure, from a third party not subject
          to any confidential obligation to the disclosing party; now or later
          becomes publicly known through no breach of confidential obligation by
          the receiving party; released by the disclosing party to any other
          person, firm or entity (including governmental agencies or bureaus)
          without restriction on use or disclosure; or independently developed
          by or for the receiving party without any reliance on or use of
          Confidential Information of the disclosing party. The foregoing
          exceptions shall not apply to software in any form.

     (d)  Disclosure and Notification.  If a receiving party receives a request
          to disclose any Confidential Information of the disclosing party
          (whether pursuant to a subpoena, an order issued by a court or other
          governmental

                                       8

<PAGE>

          authority of competent jurisdiction or otherwise) and, on
          advice of legal counsel, determines that disclosure is required under
          applicable law, the receiving party agrees that, prior to disclosing
          any Confidential Information of the disclosing party, it shall (i)
          notify the disclosing party of the existence and terms of such request
          or advice, (ii) cooperate with the disclosing party in taking legally
          available steps to resist or narrow any such request or to otherwise
          eliminate the need for such disclosure at the disclosing party's sole
          expense, if requested to do so by the disclosing party, and (iii) if
          disclosure is required, it shall be the obligation of the disclosing
          party to use its commercially reasonable efforts to obtain a
          protective order or other reliable assurance that confidential
          treatment shall be afforded to such portion of the Confidential
          Information of the disclosing party as is required to be disclosed.

     (e)  Continuing Obligation.  The obligation of non-disclosure and non-use
          with respect to Confidential Information of the disclosing party shall
          survive termination of this Agreement and shall continue for a period
          of 5 years thereafter, provided that the obligations of non-disclosure
          and non-use shall continue in perpetuity for software included in
          Confidential Information.

6.   OWNERSHIP AND LICENSE OF WORK PRODUCTS.

     (a)  Ownership.  Unless expressly provided otherwise in the applicable
          Statement of Work, the ownership of any and all right, title and
          interest in and to work products (including without limitation:
          computer programs and documentation; photographs; logos; drawings;
          artistic and graphical works; reports; data; information; and other
          works of authorship) made by Service Provider, or its suppliers or
          contractors, during performance of Services for Service Recipient in
          accordance with the applicable Statement of Work (all such works
          herein "Work Products"), shall be determined in accordance with the
          terms and conditions of the Software Development and Technical
          Services Agreement relating to ownership of intellectual property,
          with those terms and conditions being applied to any Statement of Work
          issued hereunder and being incorporated herein in their entirety by
          this reference.

     (b)  License.  Unless expressly provided otherwise in the applicable
          Statement of Work:

          (1)  If Service Provider owns any Work Products, any license granted
               to Service Recipient by Service Provider in or to any such Work
               Products shall be on the same terms and conditions as the license
               grant by GTE to GENUITY contained in the Software

                                       9

               License Agreement, with such terms and conditions being
               incorporated herein in their entirety by this reference.

          (2)  If Service Recipient owns any Work Products, and subject to
               Service Provider's obligations with respect to Service
               Recipient's Confidential Information, Service Provider shall
               retain a non-exclusive, perpetual, world-wide, royalty-free
               license to use any such Work Product for its ordinary and usual
               business purposes.

7.   DISPUTE RESOLUTION.

     (a)  General. Except as provided in subsection 7(d) below, any controversy
          or claim arising out of or relating to this Agreement, or the breach
          thereof, shall attempt to 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 subsection 7(c) below.

     (b)  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 7(b) for a minimum of sixty
          (60) days before requesting arbitration.

     (c)  Arbitration.  If the dispute is not resolved under the preceding
          subsection 7(b) within sixty (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

                                       10

<PAGE>

          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, 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.

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

8.  RELATIONSHIP OF PARTIES.

     (a)  Independent Contractors.  In providing any Services pursuant to this
          Agreement, Service Provider and its affiliates are independent
          contractors and not agents or representatives of Service Recipient.
          Persons furnished by the respective parties shall be solely the
          employees or agents of such parties, respectively, and shall be under
          the sole and exclusive direction and control of such parties. They
          shall not be considered employees of the other party or parties for
          any purpose. Each party shall also be responsible, respectively, for
          payment of taxes, including federal, state, and municipal taxes,
          chargeable or assessed with respect to its employees or agents, such
          as social security, unemployment, worker's compensation, disability
          insurance and federal and state income tax withholding.

     (b)  No Performance.  Neither party undertakes by this Agreement or any
          Statement of Work to conduct the business or operations of the other
          party. Nothing contained in this Agreement or any Statement of Work is
          intended to give rise to a partnership or joint venture between the
          parties or to impose upon the parties any of the duties or
          responsibilities of partners or joint venturers.

9.   FORCE MAJEURE.

     If performance of any Services under this Agreement 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 commercially  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.  If a force majeure condition continues to prevent a
     party from performing for more than (30) consecutive days, then the other
     party may terminate the applicable Statement of Work.

10.  REGULATORY COMPLIANCE.

     (a)  Cooperation.  This Agreement is subject at all times to any 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 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 by a regulatory agency so that the
          benefits of this Agreement may be achieved.

     (b)  Filing Agreement.  Notwithstanding the effective date and term of this
          Agreement as stated elsewhere, to the extent that any statute, order,
          rule or regulation or any regulatory agency having competent
          jurisdiction over one or both parties to this Agreement, shall require
          that this Agreement or

                                       12

<PAGE>

          subsequent amendment be filed with or approved by such regulatory
          agency before the Agreement or amendment may be effective, this
          Agreement or amendment shall not be effective in such jurisdiction
          until the first business day after such approval or filing shall have
          occurred.

11.  INDEMNIFICATION.

     (a)  General.  GTE and GENUITY, to the fullest extent permitted by law,
          each shall defend, indemnify and hold harmless the other and its
          affiliates, officers, agents and employees from any and all amounts
          payable under any judgment, verdict, court order or settlement (and
          associated fees and disbursements of counsel) arising from or related
          to any third-party claims for injury, sickness, disease or death of
          any person or damage to any real or tangible personal property or
          assets to the extent arising from the indemnitor's (either directly or
          through its officers, agents, subcontractors or representatives)
          negligence or willful misconduct in the performance of this Agreement
          provided, however, that if a claim is the result of the joint
          negligence or joint willful misconduct of GTE and GENUITY, the amount
          of the claim for which each party is entitled to indemnification shall
          be limited to that portion of such claim that is attributable to the
          negligence or willful misconduct of the indemnifying party. The
          parties agree that the price for Services provided under this
          Agreement includes consideration for the obligation to indemnify as
          set out in this subsection 13(a).

     (b)  Losses.  GENUITY and GTE each shall be responsible for any and all
          claims, actions, damages, liabilities, costs and expenses, including
          reasonable attorneys' fees and expenses (collectively, "Losses"), to
          their respective tangible personal or real property (whether owned or
          leased), and each party agrees to look only to its own insuring
          arrangements (if any) with respect to such Losses. Subject to the
          procedures set forth below, each party shall indemnify, defend, and
          hold the other party harmless from any and all Losses arising out of,
          under or in connection with claims for which the indemnitor is
          responsible under the preceding sentence.

     (c)  Waivers.  GENUITY and GTE waive all rights to recover against each
          other for any Loss to their respective tangible personal property
          (whether owned or leased) from any cause covered by insurance
          maintained by each of them, including their respective deductibles or
          self-insured retentions. GENUITY and GTE shall cause their respective
          insurers to issue appropriate waivers of subrogation rights
          endorsements to all property insurance policies maintained by each
          party. Each party shall give the other written notice if a waiver of
          subrogation is

                                       13

<PAGE>

          unobtainable or obtainable only at additional expense. If the party
          receiving such notice agrees to reimburse the other party for such
          additional expense, the other party shall obtain such waiver of
          subrogation. If a waiver is unobtainable or if a party elects not to
          pay the additional expense of a waiver, then neither party nor their
          insurers shall waive such subrogation rights.

     (d)  Conditions. The indemnification obligations set forth in this Section
          11 shall not apply unless the party claiming indemnification: (i)
          notifies the other promptly in writing of any matters in respect of
          which the indemnity may apply and of which the notifying party has
          knowledge, in order to allow the indemnitor the opportunity to
          investigate and defend the matter; provided, however, that the failure
          to so notify shall only relieve the indemnitor of its obligations
          under this Section 11 if and to the extent that the indemnitor is
          prejudiced thereby; and (ii) gives the other party full control of the
          response thereto and the defense thereof, including any agreement
          relating to the settlement thereof. However, if the indemnitor fails
          to promptly assume the defense of the claim, the party entitled to
          indemnification may assume the defense at the indemnitor's cost and
          expense. The indemnitor shall not be responsible for any settlement or
          compromise made without its prior written consent, unless the
          indemnitee has tendered notice and the indemnitor has then refused to
          assume and defend the claim and it is later determined that the
          indemnitor was obligated to assume and defend the claim. The
          indemnitee agrees to cooperate in good faith with the indemnitor at
          the request and expense of the indemnitor.

12.  LIMITATION OF LIABILITY.

     (a)  General.  A party's and its affiliates' liability arising out of or
          relating to a Statement or Statements of Work and this Agreement,
          including without limitation on account of performance or
          nonperformance of obligations hereunder, regardless of the form of the
          cause of action, whether in contract, tort (including without
          limitation negligence), statute or otherwise, shall in no event exceed
          the lesser of (i) the price to be paid to Service Provider for the
          completed Statement of Work (whether set out as a fixed price,
          estimated price, not-to-exceed amount, or other similar expression of
          the total price for the work to be performed under the Statement of
          Work); (ii) the amount actually paid by Service Recipient to Service
          Provider for the particular Statement of Work from which the claim
          arises; or (iii) if the price to be paid to Service Provider for the
          Statement of Work is expressed as a recurring periodic charge, the
          liability shall be limited to the average of three (3) months charges
          for technical services based on the average previous twelve (12)
          month's (or such lesser number of

                                       14

<PAGE>

          months that the Statement of Work has been in effect) of the invoices
          actually paid by Service Recipient under the Statement of Work. The
          limitation in the immediately preceding sentence does not apply to a
          party's obligations under the Sections entitled Indemnification and
          Confidential Information, nor does it apply to willful misconduct or
          gross negligence on the part of a party.

     (b)  Limitation.  EXCEPT FOR BREACHES RELATED TO CONFIDENTIAL INFORMATION,
          NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY INDIRECT,
          INCIDENTAL, PUNITIVE, EXEMPLARY, SPECIAL OR CONSEQUENTIAL DAMAGE OR
          LOST PROFITS OF ANY KIND WHATSOEVER EVEN IF A PARTY OR ITS AFFILIATES
          HAVE BEEN APPRISED OF THE LIKELIHOOD OF SUCH DAMAGES OCCURRING.

     (c)  Benefits Under Licenses.  Anything contained herein to the contrary
          notwithstanding, this Agreement shall not constitute an agreement to
          start work, to provide Services or Work Product or to make available
          to Service Recipient the benefits under any agreement, license or
          arrangement if doing so without the consent of and/or payment to
          another party thereto would constitute a breach thereof or in any
          material way affect the rights of Service Provider thereunder, unless
          and until such consent is obtained and payment, if any, made to such
          party by Service Provider. Service Provider shall use commercially
          reasonable efforts to secure such consents and benefits under any such
          agreement or arrangement. If Service Provider cannot: (i) obtain such
          consent; or (ii) Service Provider and the third party vendor cannot
          agree on a commercially reasonable payment, if such is required, or
          (iii) if providing the Services or Work Products or making the
          benefits under any such agreement, license or arrangement available
          would materially affect Service Provider's right thereunder, Service
          Provider shall not be required to provide any Services or Work
          Products which are dependent upon any agreement, license or
          arrangement as to which the third party provider has objected in
          writing to making the benefits of such agreement, license or
          arrangement available to Service Recipient. Service Recipient may,
          however, obtain the requisite license or pay such fees that it deems
          appropriate in order for Service Provider to provide the Services, if
          Service Provider's provision of Services pursuant to such Service
          Recipient License or payment is without any adverse material affect to
          Service Provider.

13.  CHANGES IN MANNER OF PROVIDING SERVICES.

     Service Recipient acknowledges that Service Provider and its affiliates may
     in the future determine to outsource certain information technology
     functions or

                                       15

<PAGE>

     perform such functions using different computer software operating systems
     or applications. These changes may prevent Service Provider from providing
     certain Services or Work Products to Service Recipient pursuant to this
     Agreement in the manner in which they have been provided prior to such
     change. In the event Service Provider determines to take any such action,
     it will provide Service Recipient with one hundred twenty (120) days prior
     written notice and will cooperate with Service Recipient to enable Service
     Recipient to continue to receive any affected Services and Work Products
     through arrangements with Service Provider's outsource providers or through
     conversion of Service Recipient data for use on such operating systems or
     applications. In the event Service Provider determines to make such
     changes, Service Recipient shall have the right to terminate this Agreement
     or any affected Statement of Work without any liability or penalty. Any
     customizations requested by Service Recipient within or to the systems
     utilized by Service Provider to provide the Services shall be at Service
     Provider's discretion. Service Recipient shall be required to pay the
     mutually agreed upon cost of such customizations.

14.  INSURANCE.

     (a)  Coverage.  Each of GTE and GENUITY agrees to maintain in full force
          and effect during the term of this Agreement, and so long as the

          insurance coverages: (i) Worker's Compensation and Occupational
          Disease covering each party's full liability under the Statutory
          Workers' Compensation Laws for the state in which the Service is being

          combined single limit per occurrence for Property Damage and any
          accident resulting in bodily injury or the death of one or more
          persons, and the consequential damages arising therefrom.

          contained in this Section 15 shall continue for the term of this
          Agreement and shall survive its termination.

16.  ASSIGNMENT AND SUBCONTRACTING.

     (a)  Neither this Agreement nor any rights or obligations hereunder shall
          be assignable by either of the parties hereto; provided that either
          party may delegate all or any portion of its obligations to perform

          any Statement of Work have a disability as defined in the Americans

          site or through remote facilities, to any computer or electronic data
          storage system of the other party in order to accomplish the Services
          called for in this Agreement, the party that receives such access
          shall limit such access and use solely to perform Services within the
          scope of this Agreement and shall not access or attempt to access any
          computer system, electronic file, software or other electronic
          services other than those specifically required to accomplish the
          Services required under this Agreement. Under no circumstances shall
          either party's personnel access any networks or facilities of the
          other party for the purpose of accessing other external networks, nor
          shall any such capabilities for such access be published or made known
          via any medium, as for example and not by way of limitation, posting

          material breach of this Agreement. Neither party shall use back doors,
          data capture routines, games, viruses, worms, or Trojan horses and any
          intentional introduction of such into the other party's data networks
          shall be deemed a material breach of this Agreement. The party
          receiving access shall limit such access to those of its employees

                   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

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

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.

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

difficult end-to-end or otherwise elusive problems. Genuity shall assume all

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

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.

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

(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.

     ---------------------------
represent themselves as employees of the other party in contacts with End Users

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

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

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

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

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

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;

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

parties agree that, as between them, the End User information of a customer that

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

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.

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.

     ---------
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 by a regulatory agency so that the benefits of this Agreement may be
achieved. Notwithstanding the Effective Date and term of this Agreement as
stated elsewhere, to the extent that any statute, order, rule or regulation or
any regulatory agency having competent jurisdiction over one or both parties to
this Agreement, shall require that this Agreement or subsequent amendment be
filed with or approved by such regulatory agency before the Agreement or
amendment may be effective, this Agreement or amendment shall not be effective
in such state until the first business day after such approval or filing shall
have occurred.

       ----------------------
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.


14.11. Additional Remedies. The rights and remedies set forth in this Agreement,
       -------------------
unless otherwise stated in this Agreement, are in addition to and not in
substitution of all rights and remedies available to the parties at law, in
equity, or otherwise.


14.12. Audit. During the Term and for a period of three (3) years thereafter,
       -----
each party shall keep and maintain records of amounts billed to and paid by Bell
Atlantic for Genuity Services under this Agreement in accordance with generally
accepted accounting principles.  Each party shall also keep and maintain for the
same three (3) year period, records showing compliance with the terms of this
Agreement other than billing and payment terms. Each party shall provide the
other and its representatives full and complete access to such records at all
reasonable times for purposes of audit related to a party's performance under
this Agreement, during the Term hereof and for such three (3) year period.  At
the request of the audited party, the audit shall be conducted by an

                                                                              16
<PAGE>

independent auditor chosen by the auditing party and reasonably acceptable to

any confidential customer contract, pricing or other proprietary information of
the audited party to the auditing party, except as and to the extent permitted
elsewhere in this Agreement.



14.13.  Dispute Resolution.
        ------------------

(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
prior to filing any lawsuit or administrative claim or complaint.  The parties
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
County of New York, in the State of New York. Three (3) arbitrators, each having
at least five (5) years of experience in the telecommunications field, shall be
appointed, one by each party, and then one selected jointly by those two
arbitrators, for such arbitration. Any award rendered therein shall specify the
findings of fact of the arbitrators and the reasons for such award, with
reference to and reliance on relevant law. The parties shall each be responsible
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.

14.14 Government Requirements. Genuity shall comply with applicable provisions
      -----------------------
of Attachment 2, Government Requirements.  Attachment 2 is hereby made a part of
this Agreement.  The term Consultant" in Attachment 2 shall be deemed to mean
Genuity.


14.15 Good Faith Performance. Subject to the terms and provisions of this
      ----------------------
Agreement, each party covenants that it shall take, or cause to be taken, all
lawful actions to do, or cause to be done, all things necessary, proper, or
advisable to comply with the provisions of this Agreement.  In the performance
of its obligations under this Agreement, each party covenants that it shall act
fairly and in good faith.  Where notice, approval or similar action by a party
is permitted or required by any provision of this Agreement, such action shall
not be unreasonably delayed or withheld.  The parties shall cooperate in good
faith to amend

                                                                              17

inclusion of, any non-material terms or conditions, if any.

      ----------------------------
is for the sole and exclusive benefit of the parties hereto and nothing in this
Agreement shall be construed to grant to any person other than the parties
hereto, and their respective successors and permitted assigns, any right, remedy
or claim under or in respect of this Agreement or any provision hereof.


14.17 Publicity. This Agreement shall be treated as confidential information
      ---------
of both parties and shall and protected in accordance with Section 9 hereto.
Without limiting the foregoing, neither party shall issue any press release,
advertising or other publicity material using the other party's name or marks or

                              Purchase Commitment


Bell Atlantic will use Genuity as its preferred provider of the types of
services covered in the Agreement.  Accordingly, Bell Atlantic will spend no
less than five hundred million dollars (US $500,000,000) ("Purchase Commitment")
to purchase the Genuity Services during the Initial Term, subject to the terms
and conditions of the Agreement and the following:

A.  Included Items

The following amounts, not counting taxes paid to Genuity pursuant to Section
7.8, shall be counted toward the Purchase Commitment:


1.   Any and all amounts paid and/or owed by Bell Atlantic and/or an Authorized
Affiliate to Genuity for the Genuity Services.

2.   Any and all amounts received by or owed to Genuity for the Genuity Services
or similar services that are sold by Genuity pursuant to a referral made by Bell
Atlantic under the lead referral program described in Section 1.2.

3.   Any and all amounts paid and/or owed by Bell Atlantic and/or an Authorized
Affiliate to one or more third part(ies) (i.e., a non-Bell Atlantic affiliate)
for the purchase of substitute services in the event that Genuity does not
maintain a competitive and current portfolio of services under Section 3.6, and
such failure is the proximate cause of the events described above.

4.   Any and all amounts paid and/or owed by Bell Atlantic and/or an Authorized
Affiliate to one or more third part(ies) (i.e., a non-Bell Atlantic affiliate)
for the purchase of substitute services in the event that: (i) Genuity fails to
adjust its prices or service offerings in response to commercially reasonable
End User bid opportunities pursuant to Section 3.7, and (ii) Bell Atlantic
and/or an Authorized Affiliate despite commercially reasonable efforts is or are
unable to meet commercially reasonable End User's requirements with the Genuity
Services, and (iii) and Genuity's failure to adjust its prices or service
offerings is the proximate cause of Bell Atlantic's and/or and Authorized
Affiliate's purchase of substitute services or inability to meet commercially
reasonable End User's requirement.

5.   Any and all amounts (i) paid and/or owed by Bell Atlantic and/or an
Authorized Affiliate to one or more third part(ies) (i.e., a non-Bell Atlantic
affiliate) for the purchase of substitute services, in the event that Genuity
fails to comply with Section 7.4 and such failure is the proximate cause of the
events described in subsection above.  To the extent such amounts are included
in Section 4 of this Attachment 1, they shall not also be counted herein.

6.   Any and all amounts that Bell Atlantic can reasonably establish would have
been paid and/or owed by Bell Atlantic or an Authorized Affiliate to Genuity for
one or more of the Genuity Services to the extent that Bell Atlantic terminates
the Service Schedule with respect to such Genuity Services due to a default in
accordance with Section 6.2, or due to a regulatory or legal prohibition in
accordance with Section 6.3.

B.  Interim Purchase Commitment Milestone

There shall be an interim Purchase Commitment (the "Interim Purchase
Commitment") of two hundred million dollars ($200,000,000) measured at the end
of the third year following the Effective Date.

                                                                              19
<PAGE>

C.  Shortfall Charge


In the event that Bell Atlantic has failed to satisfy the Interim Purchase
Commitment by the end of the third year following the Effective Date, and to the
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
Agreement, or is not otherwise excused under the Agreement (e.g., Force
majeure), Bell Atlantic shall pay Genuity the difference between the Interim
Purchase Commitment and the total of the Included Items specified in Section A,
above, for years 1 through 3 (the "Interim Shortfall Charge").


In the event that Bell Atlantic has failed to satisfy the Purchase Commitment by
the end of the Initial Term, and to the 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 Agreement, or is not otherwise
excused under the Agreement (e.g., Force majeure), Bell Atlantic shall pay
Genuity the difference between: (i) the Purchase Commitment less any Interim
Shortfall Charge; and (ii) and the total of the Included Items specified in A,
above for the Initial Term (the "Shortfall Charge").


D.  Payment


Genuity shall invoice Bell Atlantic for any Interim Shortfall Charge owed within
ninety (90) days after the completion of year 3, and for any Shortfall Charge
within ninety (90) days after the expiration of the Initial Term.  Such invoices
shall set forth with particularity the basis for the Interim Shortfall Charge or
the Shortfall Charge, as applicable.  Bell Atlantic may dispute such invoice in
accordance with Section 14.13 of the Purchase, Resale and Marketing Agreement,
and may, prior to attempting to end such dispute, conduct an audit of all of
Genuity's or its agents' records that may be reasonably relevant in calculating
the Shortfall Charge.

     -----------------------------------------
Atlantic with forty-five (45) days advance written notice of any new releases of

Genuity's ability to obtain the regulatory, legal, vendor, and import and export
approvals (including those required for resale of Internet connectivity) as

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 agreement.

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

the regulatory, legal, vendor, and import and export approvals (including those
required for encryption technology) as Genuity deems necessary and under such

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

     -----------------------------
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.

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

     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

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

     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

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

IS IN ADDITION TO, NOT INSTEAD OF, THE DISCLAIMER,  LIMITATION OF LIABILITY AND

1).  Volume Discounts

Volume Discounts will be calculated in accordance with the attached pricing
schedules.  Volume discounts apply to each Service, except for Services and/or
Service components excluded within the applicable price schedule.

2).  Multi-Service Discounts

The Multi-Service Discount for a particular calendar month shall be based upon
the total monthly volume of all eligible Genuity Services purchased by Bell
Atlantic under this Agreement in that calendar month.  The Genuity Services
eligible for such discount are those services and products listed in Attachments
B-1, B-2, B-3 and B-4 ("Eligible Services").

However, the Multi-Service Discount shall not be available if more that 60% of
the total monthly volume in the particular calendar month is derived solely from

Certain line items and "pass through" costs within certain Genuity Services
shall not be eligible for a Multi-Service Discount ("Excluded Services").  Such
items are listed in Attachment B-5 ("Summary of Exclusions from Multi-Service
Discount").

The Multi-Service Discount will apply as follows:

     Total billing to Bell Atlantic for all Eligible Services (excluding any
     Excluded Services) per month:

     $5m - #$10m    = 1% Multi-Service Discount
     $10m - #$20m   = 2% Multi-Service Discount

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

<PAGE>

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.

DIALINX v2.3 BELL ATLANTIC WHOLESALE RATE SCHEDULE

Definitions: (for purposes of this Attachment only)
- -------------

 .    Genuity Inc.         Genuity
 .    GTE/Bell Atlantic    Bell Atlantic
 .    Customer             Each and every direct customer of Bell Atlantic
 .    End User             Each and every end user of a Customer of Bell Atlantic

 .    Service rates correspond to the rates outlined below. Network volume
     discounts are automatic and dynamic, (e.g., Bell Atlantic may receive a
     lower component price one month, and higher rate the next month due to
     monthly usage variables.)

 .    During the month in which any link, equipment, or service is installed or
     de-installed, the Pro-Rated Monthly Charge, will be billed based upon a 30
     day calendar month for each day following Genuity's commencement of the
     applicable service. For example, for equipment installed or de-installed,
     the Customer will be billed 1/30 of the Monthly Charge, for each day
     following commencement of the service for that billing period.

CUSTOMER SET-UP FEES

 .    Bell Atlantic will be charged a per customer set-up fee based on
     provisioning up to 5 realms pointing to the same RADIUS IP address.
     Additional realms are outlined in more detail elsewhere in this document.

     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.

** If one of the service elements is dependent on another service element that
has a longer provisioning element, (e.g., RADIUS Servers/Directional Filtering)
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 SLAs can be enacted per Bell

** 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
diagram and a completed end-user questionnaire, all of
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.

     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.

provided by Genuity.  In no event will the untimely installation or non-
operation of Bell Atlantic's or its End User's facilities, services, or
equipment (including local exchange Access, Bell Atlantic premise equipment and
CPE) relieve Bell Atlantic of its obligation to pay charges for Services as of
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
Date, Bell Atlantic shall have the option of extending the Projected Delivery
Date for not more than thirty (30) days.  All third party charges to Genuity

agent shall be charged pursuant to Section 10.

F.  Bell Atlantic shall make the determination of whether an End User should be
disconnected due to security concerns provided that nothing in this Section
shall impact Genuity's rights under Section 21 of this Service Schedule.

G.  Bell Atlantic shall be responsible for providing sales engineering, order
entry, first level repair support, coordination of provisioning activities, and
for billing and billing inquiries to Services for End Users, as applicable and
other such services.


10. Training.  Within ninety (90) days after the Effective Date of the
    --------
Agreement, Genuity and Bell Atlantic shall complete a mutually agreed training
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
in quarterly product and technical update training.  Furthermore, Genuity will
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

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.

The Parties agree to use the following process in Custom Bid situations:

     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
     date.  The Custom Bid Request form will be reviewed and approved by Bell
     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.

H.  The Acceptance Certificate signed by Bell Atlantic does not relieve in any
way the obligation upon Genuity to carry out in full all its obligations under
this Agreement.

                                      19
<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.

K.  Cooperative efforts around Market Readiness Testing (MRT), which involves
limited market introduction to Beta-customers, have to be agreed/detailed
between the Parties.

25. Network Review Meetings.  Bell Atlantic and Genuity agree to hold quarterly
    -----------------------
meetings or more frequently as mutually agreed, to work cooperatively on items
such as, but not limited to, forecast information, future network deployment
schedules, network enhancements, additional Access providers, Type II Access
arrangements, new services, performance reviews, defect resolution, business
processes and interaction, price reviews, and standards and specifications, and
Agreement performance.  Chairpersons to be designated by Bell Atlantic and
Genuity will jointly chair this effort.

26. Security.  Genuity shall administer access, both physically and
    --------
electronically, to all Genuity Network elements, associated support and/or
management systems, and physical PoP facilities that are under direct control of
Genuity. Genuity shall maintain all data associated with the security of the
Genuity Network. Genuity will use commercially reasonable resources and/or means
available to detect Genuity Network security breaches. Genuity shall use
commercially reasonable efforts to promptly provide pertinent information to
Bell Atlantic to assist Bell Atlantic in the identification and potential
prosecution of Network intruders. Genuity shall use

                                      20
<PAGE>

commercially reasonable efforts to promptly restore Genuity Network integrity
(not including End User databases) after Network intrusions. Genuity shall
provide protected storage of Genuity Network and Genuity Network element
configuration data. Genuity shall block and/or disconnect (as appropriate for
the Service) and with direction and/or authorization from Bell Atlantic, an End
User's access to the Network in which a security violation has occurred, at Bell
Atlantic request. Notwithstanding the foregoing, Genuity reserves the absolute
right to block or disconnect certain Services and/or connectivity if Genuity
reasonably believes that such Services/connectivity may affect Genuity Network
integrity or security; under such circumstances Genuity will provide notice to
Bell Atlantic of such action as soon as practicable and in advance where
feasible. Genuity shall provide access to Bell Atlantic for viewing of Bell
Atlantic Service data only as set forth in Section 15 of this Service Schedule.

27. Limited Warranty. The Genuity warranty is set out in Section 11 of the
    ----------------
Agreement.

28. Epidemic SLA Remedy.
    -------------------

A.  An Epidemic for a Service (e.g. ATM or Private Line) shall occur when the
elements in both subsections (i) and (ii) below have occurred with respect to
the affected Service:

(i) Failure of the greater of (a) the minimum number of circuits per Service or
(b) the minimum percentage of circuits per Service (as specified in the table
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.

The SLA Credit/Remedy for Time to Restore (TTR) is accounted for in the Circuit
Availability SLA set forth in 2.4.5.  TTR is not a parameter that is directly
measured for SLA crediting.

TTR shall be the cumulative amount of time (minutes/hours) between the opening
of a trouble ticket by Genuity and the closeout process set forth in the Service
Schedule and its' attachments.

2.4.5  Circuit Availability SLA Credit/Remedy

The Private Line Circuit Availability is designed to meet the availability
requirements as shown in Table 2.4.1-1.  Tables 2.4.5-1, 2.4.5-2, and 2.4.5-3
contain references to metric definitions and SLA remedies described within this
document.

A Service outage ("Outage") shall begin upon the earlier of Genuity's actual
knowledge of the Outage or Genuity's receipt of a telephone call to the
telephone number designated in the Trouble Reporting Attachment of this Service
Schedule.

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.

                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).

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.

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

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.

<PAGE>

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.)

*Note for Provisioning* - If the PVC starts with the same number and has a
different letter following it, then this will indicate a bi-directional PVC is
being ordered ( ex 1A and 1B), you will select "Bi-Directional" option in the
Circuit Part field on NOMES Circuit Screen; Otherwise use "Uni-Directional".

                                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.

governed by the terms and conditions of this Agreement. The foregoing license
grant also shall include the right of GENUITY to make a reasonable number of
copies of the Documentation for use with the Licensed Programs; provided,
however, that all titles, trademarks, copyright, patent and other proprietary
rights notices relating to Intellectual Property Rights shall be reproduced in
such copies and such copies are stored in a safe and secure place. All such
copies, in whole or in part, of any Documentation shall be governed by the terms
and conditions of this Agreement.

         (c) GTE and GENUITY shall enter into a Software Escrow Agreement,
substantially in the form attached hereto as Exhibit D, for the Licensed
Programs identified in Schedule A as requiring the escrow of source code, which
shall set forth the terms and conditions pursuant to which source code for the
identified Licensed Programs will be made available to GENUITY. In the event
that such source code is released to GENUITY pursuant to the Software Escrow
Agreement, GTE shall grant to GENUITY a limited, personal, nontransferable and
nonexclusive license to use such released source code solely for the purpose of
maintaining the Licensed Programs during the License Term. Said license shall
not be transferable or sublicensable, and shall not include the right to create
any new versions, enhancements or other modifications of the Licensed Programs.
The said license shall include the right to have the Licensed Software
maintained by a third party, upon GTE's prior written approval, which approval
shall not be unreasonably withheld.



                                       3

         (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
whatsoever (except as otherwise expressly provided in Section 3.1(b)), (ii) make
the Licensed Software, or any portion thereof, available to any other person or
entity, whether on a time-sharing basis or otherwise, (iii) Use or otherwise
exploit the Licensed Software for the benefit of any other person or entity, or
(iv) modify or create works derivative of the Licensed Software or any portion
thereof. Except and to the extent expressly set forth in Schedule A, such
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
Software license agreement is included with such Third Party Software, in which
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.

         3.3. Ownership.

         GENUITY acknowledges and agrees that (i) GTE is and shall remain the
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
Rights therein, and that GENUITY acquires no rights in or to any of the
foregoing, other than the license rights expressly granted herein (or in the
instance of Third Party Software, the rights granted by the third party).
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.

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
remedy, and GTE's entire liability, for breach of the warranty set forth in this
Section 8.3 shall be, at GTE's option and sole expense: to attempt to correct
any nonconforming Licensed Programs; to replace any nonconforming Licensed
Programs with a corrected copy upon return to GTE of all of GENUITY's copies of
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.

         8.4. Disclaimer. EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION 8 GTE
MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR
ARISING BY CUSTOM OR TRADE USAGE, WITH RESPECT TO THE GTE PRODUCTS OR OTHERWISE
IN CONNECTION WITH THIS AGREEMENT. WITHOUT LIMITING THE FOREGOING, GTE EXPRESSLY
DISCLAIMS ANY EXPRESS OR IMPLIED WARRANTY OR REPRESENTATION (i) THAT ANY GTE
PRODUCTS OR ANY OF THEIR USE OR ANY ACTIVITIES OF GENUITY CONTEMPLATED BY THIS
AGREEMENT, SHALL BE FREE FROM INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS
OF ANY THIRD PARTY, (ii) AS TO THE QUALITY OR PERFORMANCE OF ANY GTE PRODUCTS OR
SERVICES, AND (iii) OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE EVEN
IF GTE HAS BEEN ADVISED OR SHOULD HAVE KNOWN OF SUCH PURPOSE. GENUITY SHALL BE
SOLELY RESPONSIBLE FOR ADEQUATE PROTECTION AND BACKUP OF GENUITY'S DATA AND
SOFTWARE USED IN CONNECTION WITH ITS USE OF GTE



                                       9

9. Limitation of Liabilities.

         9.1. UNDER NO CIRCUMSTANCES SHALL GENUITY BE ENTITLED TO RECOVER FROM
GTE ANY INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL OR PUNITIVE DAMAGES
(INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF BUSINESS, LOSS OF PROFITS OR
LOSS OF USE), WHETHER BASED ON CONTRACT, TORT (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE), OR ANY OTHER CAUSE OF ACTION RELATING TO GTE PRODUCTS, OR OTHERWISE
RELATING TO THIS AGREEMENT, EVEN IF GTE HAS BEEN INFORMED OR SHOULD HAVE KNOW OF
THE POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL THE LIABILITY OF GTE (WHETHER
BASED ON CONTRACT, TORT (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR ANY OTHER
CAUSE OF ACTION) EXCEED THE AGGREGATE AMOUNT OF PAYMENTS ACTUALLY RECEIVED BY
GTE DURING THE LAST YEAR OF THE LICENSE TERM PURSUANT TO SECTION 4.1.

         9.2. Third Party Claims. Without limiting the foregoing Section 9.1,
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
based on or related to GENUITY's Use of the Licensed Software, errors or alleged
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. Confidential Information.

         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
or contained within the Confidential Information or any portion thereof; or (vi)
not copy or otherwise duplicate any Confidential Information, in whole or in
part, including, without limitation, derivations, except and to the extent
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
<PAGE>

         10.3. Marking. Any copy of the Confidential Information authorized by
GTE to be made by GENUITY pursuant to this Agreement shall conspicuously display
markings or statements of GTE appearing on the originals of such Confidential
Information.

         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.

11. Term, Termination.

         11.1. License Term. This Agreement shall be effective as of the
Effective Date and, unless otherwise terminated or cancelled as provided herein,
remain in effect for a period of one (1) year from the Effective Date (the
"License Term"). The License Term for each Licensed Software shall be
automatically renewed for successive one (1) year periods upon the payment of
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
         under a federal reorganization act;

                  (d) A trustee or receiver is appointed by a court for all or a
         substantial portion of the assets of the other;

                  (e) The other becomes insolvent or suspends its business; or

                  (f) The other makes an assignment of its assets for the
         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
of any of the terms, conditions or covenants of this Agreement by the other;
provided, however, that such termination or cancellation may be made only
following the expiration of a thirty (30) day period during which the other
party has failed to cure such breach after having been given written notice
thereof.

         11.4. Other Termination. GENUITY may terminate or cancel any license
for any Licensed Software upon thirty (30) days prior written notice to GTE and
the rights and licenses for such terminated or cancelled Licensed Software shall
immediately terminate at the end of such thirty (30) day period or such earlier
period as specified in the notice. Notwithstanding termination or cancellation
of any license for any Licensed Software, no refund or credits shall be due or
owing to GENUITY.



                                       11
<PAGE>

         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
instance of termination, cancellation or expiration of specific Licensed
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
prior to the date of expiration, termination or cancellation. Notwithstanding
anything herein to the contrary, upon any expiration or termination of this
Agreement, the provisions of Sections 2, 3.2, 3.3, 4, 6, 7.1, 8.4, 9, 10, 11, 12
and 13 shall survive such expiration, termination or cancellation and shall

         (d) With respect to Third Party Software in which GTE acquires rights
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
amortizes costs associated with such Third Party Software, GENUITY shall pay the
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

         3.3. General Conduct of Technical Efforts. The parties acknowledge and
agree that the successful completion of each Technical Effort shall require the
cooperation of both parties. GTE shall endeavor to complete each Technical
Effort in accordance with the Schedule. GTE may, at its election, perform its
obligations under this Agreement either directly or through one or more
Affiliates, unless otherwise provided in a Statement of Work. GENUITY agrees to
provide such information and access to facilities, personnel and GENUITY Legacy
Systems, if applicable, as may be reasonably required or requested by GTE to
complete the Technical Effort. If GENUITY's acts or failures to act cause any
hindrance or delay in GTE's performance of the Technical Effort, the time for
GTE's performance under the Schedule shall be extended accordingly and GENUITY
shall pay GTE, at GTE's then current rates, for any additional time spent, and
reimburse GTE for any additional expenses incurred, as a result of such
hindrance or delay.

         3.4. Technical Effort Coordinators and Technical Effort Teams.

         (a) For each Technical Effort, each party shall specify one Technical
Effort Coordinator who shall be designated to act that party's contact person
relating to the over-all conduct of the Technical Effort.

         (b) Each party shall assign to the Technical Effort such personnel (its
"Technical Effort Team") and other resources as may be reasonably necessary to
complete the Technical Effort.

         (c) Either party shall be free to change the identity of the Technical
Effort Coordinator and Technical Effort Team members upon reasonable notice to
the other party.

         (d) The GENUITY Technical Effort Coordinator and such other personnel
as are necessary shall be available during the term of the Technical Effort to
provide to GTE promptly on request all information regarding the Technical
Effort and the Specifications, if applicable, that is reasonably necessary for
GTE's completion of the Technical Effort.



                                       4
<PAGE>

         3.5. Progress Meetings. In the course of each Technical Effort, GTE and
GENUITY shall meet on a regular basis to review progress to date. The meetings
shall take place on or about the dates indicated in the Schedule, and in no
event less frequently than once each quarter-year. The meetings shall be
attended by each party's Technical Effort Coordinators and such other members of
their Technical Effort Teams as may be required adequately to assess the
progress of the Technical Effort, any technical or other difficulties that may
have been encountered, and to establish schedules and plans for its successful
completion

         3.6. Access to Legacy Systems. Promptly following execution of each
Statement of Work related to Legacy Systems, GENUITY shall, without charge,
provide to GTE copies of the Object Code and (to the extent required to perform
the relevant Statement of Work) Source Code for all GENUITY Legacy Systems with
which the Software to be developed under the Statement of Work must interact,
communicate with or that is in any other way required for the completion of the
Technical Effort, together with all user manuals and other documentation
relating to the Legacy Systems, unless such Legacy Systems are owned by GTE and
are only licensed to GENUITY pursuant to a separate software license agreement.
GENUITY shall also provide to GTE, free of charge, access to all computer
hardware and networks on which or within which the Legacy Systems operate to the
extent reasonably required to complete each Technical Effort. During the term of
this Agreement, GENUITY shall provide to GTE all updates, new releases and new
versions of the GENUITY Legacy Systems in the same form in which such was
originally provided, unless such updates, new releases and new versions are
provided by GTE. During the term of each Technical Effort, GENUITY shall provide
GTE (or cause to be provided to GTE), without charge, with all maintenance and
support services with respect to the Legacy Systems which subscribers to
maintenance and support services for such products receive generally, unless
such maintenance and support services are provided by GTE. With respect to any
Source Code owned by GENUITY and provided to GTE under this Agreement, GTE shall
use the Source Code for the Legacy Systems solely for the purpose of performing
GTE's obligations under the Statement of Work or Statements of Work for which
such Source Code is necessary, and shall not disclose, without GENUITY's prior
consent, such Source Code to anyone other than GTE and its Affiliates who are
performing services with respect to such Statement of Work.

         3.7. Inspection of Facilities. GTE shall advise GENUITY in writing of
the location of all facilities at which it is utilizing Source Code for the
GENUITY Legacy Systems. GENUITY 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 GTE's use of
such Source Code and GTE's compliance with its obligations with respect to the
confidentiality of such Source Code. GTE shall provide reasonable assistance to
GENUITY for such inspection, GENUITY shall minimize the amount of time that it
is required to spend in GTE's facilities, and GENUITY shall coordinate all such
activities with GTE so as not to unreasonably interfere with GTE's operations.



                                       5
<PAGE>

         3.8. Specifications and Change Orders.

         (a) The Specifications for the Software to be developed during each
Technical Effort shall be as set forth in the Statement of Work for that
Technical Effort. No change in the Specifications shall be binding upon either
party unless it has been incorporated into a written Change Order signed by the
Technical Effort Coordinator for both parties.

         (b) If GENUITY wishes to change the Specifications for any Software, it
shall give GTE written notice of such request. GTE shall respond to such request
within thirty (30) days, including in its response any change in the Schedule,
amounts to be paid, Technical Effort Teams or other matters that may be required
by the proposed change. The parties shall thereupon negotiate in good faith for
a Change Order incorporating the changes in the Statement of Work required by
the requested changes. Either party may, however, decline in its discretion to
enter into any proposed Change Order.

         (c) In no event shall GENUITY or GTE be bound by any proposed change
unless and until it has signed a Change Order for such change, and the Statement
of Work for the Technical Effort shall remain in full force and effect, without
modification, until such Change Order has been agreed upon and signed.

4. Delivery and Acceptance Procedure.

         4.1. Delivery Period. GTE shall provide each Deliverable to GENUITY in
accordance with the Schedule for the relevant Technical Effort. All
Deliverables, if any, shall be provided in the form of Object Code, unless
otherwise specified in the Statement of Work, except GTE shall also provide
Source Code and Documentation for Deliverables to be owned by GENUITY under an
Exclusive Statement of Work. GTE shall also deliver Documentation for the
Software as may be required by the Statement of Work.

         4.2. Acceptance. The procedure for delivery and acceptance of
Deliverables by GENUITY, to the extent acceptance is contemplated by the
applicable Statement of Work and a procedure for such delivery and acceptance is
not otherwise provided therein, shall be in accordance with the following.

         (a) The Statement of Work shall specify the procedure and criteria, if
any, that GTE must meet in order for the Deliverables described in a Statement
of Work to be accepted by GENUITY. The Statement of Work shall also specify a
test plan, such other information as GTE and GENUITY mutually deem appropriate
and the period of time that GENUITY shall have to provide notice of acceptance
or rejection to GTE. However, failure to accept or reject such Deliverable
within the specified period of time or the commercial use of such item by or for
the benefit of GENUITY shall be deemed to be acceptance.



                                       6
<PAGE>

         (b) If GENUITY rejects a Deliverable, it shall specify in reasonable
detail in writing the reasons for rejection and the requirements for revision.
If the notice of rejection is not sufficiently detailed to allow GTE to
determine why such Deliverable is unacceptable, GTE may request in writing that
GENUITY provide sufficient additional information, indicating the type of
additional information required by GTE. If GTE and GENUITY have joint
responsibility for the Deliverable and the Deliverable requires revision, GTE
shall assist GENUITY in making revisions necessary for the Deliverable to meet
the acceptance criteria within a period of time that is reasonable under the
circumstances. If GTE has sole responsibility for the Deliverable, then it shall
make the necessary revisions within a period of time that is reasonable under
the circumstances.

5. Payment.

         5.1. Payment. GENUITY shall pay the amounts that are charged to
GENUITY, and GTE shall invoice GENUITY, in accordance with the Statement of
Work. Each invoice shall reference this Agreement and the applicable Statement
of Work. The invoices shall be itemized to show the details as to all billed
items. Payments shall be made within thirty (30) days from the date of each
invoice.

         5.2. Taxes. In addition to any payments required by a Statement of
Work, 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 with respect to the Deliverables, Services and
other services, materials and rights provided by GTE hereunder lawfully levied
by a duly constituted governmental authority and for which GTE is required or
permitted, by law, to collect from GENUITY. In addition each party shall be
responsible for all real and personal property taxes imposed on software and
equipment owned by the respective parties on January 1 of every year; provided,
however, GENUITY shall be responsible for such real and personal property taxes
imposed upon any Deliverables provided to GENUITY. If GENUITY determines that
any Deliverables, Services and other services, materials and rights provided by
GTE hereunder are exempt from a tax, GENUITY must provide GTE a properly
completed exemption certificate, for each jurisdiction 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.



                                       7

         5.3. Expenses. GENUITY shall reimburse GTE for reasonable expenses for
travel, meals and lodging incurred by them in the performance of its obligations
under this Agreement. Any such charges shall be in compliance with such GTE's
employee expense policies. There shall be no mark-up of such expense charges.
GTE shall maintain documentation of expenses incurred, and shall provide copies
of invoices of $100 or more upon GENUITY's request. GTE shall bill GENUITY
monthly for expenses as they accrue. The parties shall specify any limitation on
the reimbursement of expenses in the applicable Statement of Work. It is
acknowledged and agreed that if GTE is required to incur expenses beyond such
limitation in order to perform its obligations under the applicable Statement of
Work or under this Agreement, then GTE is excused from performing such
obligations until said expense limitation is removed or changed as mutually
agreed; provided, however, that GTE promptly notifies GENUITY of the need to
exceed the limitation.

         5.4. Records. GTE shall maintain complete and accurate records in a
form consistent with generally accepted accounting practices, to substantiate
any charges. GTE shall retain, and make available upon request, such records for
a period of three (3) years from the date of invoice for them. GENUITY and its
authorized agents, subject to obligations of confidentiality as set forth in
this Agreement, shall have access to such records upon prior written request
during normal business hours during the term of this Agreement and during the
respective periods in which GTE is required to maintain such records pursuant to
this Section 5.4. Access to the records shall be made at the location where such
records are normally maintained.

6. Intellectual Property.

         6.1. Ownership.

         (a) Subject to GENUITY'S payment in full and compliance with all other
terms and conditions of this Agreement, and except as may be otherwise set forth
in a Statement of Work, GTE agrees to (i) transfer to GENUITY all right, title

and covenants to GENUITY that:

                  (a) In performing the Services set forth in any Statement of
         Work, GTE shall comply with all applicable laws, codes, ordinances,
         orders, rules and regulations of local, state, and federal governments
         and agencies and instrumentalities, including, but not limited to,
         applicable wage and hour, safety and environmental laws, and all
         standards and regulations of appropriate regulatory commissions and
         similar agencies.

                  (b) All Services furnished by GTE in accordance with a
         Statement of Work shall be performed by qualified personnel at a level
         of professional performance standard within the industry in which the
         Services are provided.

         8.2. Disclaimer. THE WARRANTIES IN THIS SECTION 8 AND ANY WARRANTY IN A
STATEMENT OF WORK, BUT ONLY IF SPECIFICALLY IDENTIFIED AS AN EXPRESS WARRANTY IN
SUCH STATEMENT OF WORK, ARE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,
OR WHETHER ARISING BY COURSE OF DEALING OR PERFORMANCE, CUSTOM, USAGE IN THE
TRADE OR PROFESSION OR OTHERWISE, INCLUDING BUT NOT LIMITED TO, IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE OR WARRANTIES
AGAINST INFRINGEMENT. GTE MAKES NO WARRANTIES REGARDING THE DELIVERABLES,
INCLUDING, WITHOUT LIMITATION, SOFTWARE, OR SERVICES TO BE PROVIDED HEREUNDER,
EXPRESS, IMPLIED OR ARISING BY CUSTOM OR TRADE USAGE, AND SPECIFICALLY DISCLAIMS
THE IMPLIED WARRANTIES OF MERCHANTABILITY, NONINFRINGEMENT AND FITNESS FOR A
PARTICULAR PURPOSE. Except for the warranties expressly set forth in this

<PAGE>

         8.3. Survival. All representations, warranties and covenants of GTE
contained in this Section 8 shall continue for the term of this Agreement and
shall survive its termination.

9. Indemnification.

         9.1. Indemnity for Infringement of Third Party Intellectual Property.

         (a) Indemnity regarding Deliverables provided under Exclusive
Statements of Work. If a Deliverable under an Exclusive Statement of Work become
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 Deliverable 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 Deliverable pursuant to
this Agreement; or (iii) require GENUITY to cease using and return such
Deliverable upon a Markman determination that the patent claims on which an
action has been brought are afforded a construction which outside counsel for
GTE reasonably believes reads on the Deliverable or a decision of infringement,
whichever is earlier, in which case GTE shall refund to GENUITY a pro-rata
portion of the amount actually paid to GTE by GENUITY for such Deliverable.
Notwithstanding the foregoing, if GTE exercises its right to require the return
of such Deliverable, to the extent permitted by applicable law, GENUITY may
retain and continue to use such Deliverable 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
Deliverable.

         (b) Indemnity regarding Deliverable provided under Non-Exclusive
Statements of Work. If a Deliverable under a Non-Exclusive Statement of Work
become 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 Deliverable 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 Deliverable pursuant to
this Agreement; or (iii) require the return of such Deliverable and terminate
GENUITY's right to use the same and refund to GENUITY a pro-rata portion of the
amount actually paid to GTE by GENUITY for such Deliverable. Notwithstanding the
foregoing, if GTE exercises its right to require the return of such Deliverable
and terminates GENUITY's right to use the same, to the extent permitted by
applicable law, GENUITY may retain and continue to use such Deliverable 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 Deliverable.



                                       13
<PAGE>

         (c) Limitations. GTE shall not be liable to GENUITY for any claims of
inducement to infringe or contributory infringement or claims of infringement
resulting from the combination of the Deliverable 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
Deliverable 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 Deliverable is used outside
of the scope of the rights and licenses granted to GENUITY or in a manner for
which the Deliverable was not designed; (iii) the Deliverable 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; (iv) GENUITY uses the Deliverable as part of a patented process
and there would be no infringement in the use of the Deliverable alone; or (v)
the infringement is the necessary result of GTE's compliance with specifications
or written instructions provided by GENUITY to GTE, misuse of a third party's
Confidential Information provided by GENUITY to GTE or use of Legacy Systems
provided by GENUITY to GTE . For all of the foregoing exclusions, GENUITY shall
defend and indemnify GTE for any infringement claims to the extent set forth in
Section 9.1(a).

         (d) The foregoing sets forth GTE's sole and exclusive obligations, and
GENUITY's sole remedies, for infringement of any Intellectual Property Rights by
any Deliverables under any Statement of Work.

         9.2. General. GTE and GENUITY, to the fullest extent permitted by law,
each shall defend, indemnify and hold harmless the other and its Affiliates,
officers, agents and employees from any and all amounts payable under any
judgment, verdict, court order or settlement (and associated fees and
disbursements of counsel) arising from or related to any third-party claims for
injury, sickness, disease or death of any person or damage to any real or
tangible personal property or assets to the extent arising from the indemnitor's
(either directly or through its officers, agents, subcontractors or
representatives) negligence or willful misconduct in the performance of this
Agreement; provided, however, that if a claim is the result of the joint
negligence or joint willful misconduct of GTE and GENUITY, the amount of the
claim for which each party is entitled to indemnification shall be limited to
that portion of such claim that is attributable to the negligence or willful
misconduct of the indemnifying party. The parties agree that the payments
required by any Statement of Work provided under this Agreement includes
consideration for the obligation to indemnify as set out in this Section 9.



                                       14

         9.3. Losses. GENUITY and GTE each shall be responsible for any and all
claims, actions, damages, liabilities, costs and expenses, including reasonable
attorneys' fees and expenses (collectively, "Losses"), to their respective
tangible personal or real property (whether owned or leased), and each party
agrees to look only to its own insuring arrangements (if any) with respect to
such Losses. Subject to the procedures set forth below, each party shall
indemnify, defend and hold the other party harmless from any and all Losses
arising out of, under or in connection with claims for which the indemnitor is
responsible under the preceding sentence.

         9.4. Waivers. GENUITY and GTE waive all rights to recover against each
other for any Loss to their respective tangible personal property (whether owned
or leased) from any cause covered by insurance maintained by each of them,
including their respective deductibles or self-insured retentions. GENUITY and
GTE shall cause their respective insurers to issue appropriate waivers of
subrogation rights endorsements to all property insurance policies maintained by
each party. Each party shall give the other written notice if a waiver of
subrogation is unobtainable or obtainable only at additional expense. If the
party receiving such notice agrees to reimburse the other party for such
additional expense, the other party shall obtain such waiver of subrogation. If
a waiver is unobtainable or if a party elects not to pay the additional expense
of a waiver, then neither party nor their insurers shall waive such subrogation
rights.

         9.5. Conditions. The indemnification obligations set forth in this
section shall not apply unless the party claiming indemnification: (i) uses its
best efforts to notify the other promptly in writing, of any matters in respect
of which the indemnity may apply and of which the notifying party has knowledge,
in order to allow the indemnitor the opportunity to investigate and defend the
matter; provided, however, that the failure to so notify shall only relieve the
indemnitor of its obligations under this Section 9 if and to the extent that the
indemnitor is prejudiced thereby; and (ii) gives the other party full control of
the response thereto and the defense thereof, including any agreement relating
to the settlement thereof; provided, however, that the indemnitee shall have the
right to participate, on a non-interfering basis, in any legal proceeding to
contest and defend a claim for indemnification involving a third party and to be
represented by legal counsel of its choosing, all at the indemnitee's sole cost
and expense. However, if the indemnitor fails to promptly assume the defense of
the claim, the party entitled to indemnification may assume the defense at the
indemnitor's cost and expense. The indemnitor shall not be responsible for any
settlement or compromise made without its prior written consent, unless the
indemnitee has tendered notice and the indemnitor has then refused to assume and
defend the claim and it is later determined that the indemnitor was obligated to
assume and defend the claim. The indemnitee agrees to cooperate in good faith
with the indemnitor at the request and expense of the indemnitor.

         12.1. General. Any controversy or claim arising out of or relating to

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 Section 12.3 below.

         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, and the dispute does
not relate to Intellectual Property Rights, 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.

         (b) In certain circumstances, it may be possible to obtain Other
Intellectual Property in and to Jointly-Owned Non-Statutory Intellectual
Property. Notwithstanding joint ownership of Jointly-Owned Non-Statutory
Intellectual Property, the right to seek any Other Statutory Intellectual
Property on the Jointly-Owned Intellectual Property, and the ownership in and to
any right, title and interest of any such Other Intellectual Property that may
result, shall be determined in accordance with the following:

         (i)      for any and all Other Intellectual Property in and to works of
                  authorship and mask works that are Jointly-Owned Non-Statutory
                  Intellectual Property, the party or parties that employ at
                  least one author of such work (or in the case of a
                  work-for-hire, one contributor to such work) immediately after
                  the Effective Date shall have the right to seek such Other
                  Intellectual Property in and to such works and shall
                  exclusively own, as between the parties, all right, title and

                  is employed immediately after the Effective Date by each of
                  the parties hereto, all right, title and interest in and to
                  such Other Intellectual Property that results therefrom shall
                  be jointly owned by both parties, without the obligation of
                  either party to account to the other therefor; and

         (iii)    in the event that the author(s) or contributor(s), as the case
                  may be, is not employed by any of the parties hereto, all
                  right, title and interest in and to such Other Intellectual
                  Property that results therefrom shall be jointly owned by
                  GENUITY and GTE, with neither party having a duty to account
                  to the other for the exploitation thereof.

         3.5. Preparation, Prosecution and Enforcement of Intellectual Property
Rights. Except as provided below for jointly-owned Intellectual Property Rights,
the owner of the Intellectual Property Rights, at its expense, shall control the
preparation, filing and prosecution of any patent applications directed to such
Intellectual Property Rights and to the maintenance and enforcement of any
patents that result therefrom, and the other party hereto shall cooperate with
the owner in such efforts at the owner's reasonable request and expense. For
purposes of Intellectual Property Rights which are jointly owned, GTE shall
control the preparation, filing and prosecution of such Intellectual Property
Rights and the cost thereof shall be borne equally by GTE and GENUITY; provided,
however, that (i) GTE will consult with GENUITY regarding the choice of foreign
jurisdictions in which to protect such Intellectual Property Rights; (ii) GTE
will provide copies of all documents filed with or received from the relevant
patent or other government offices in connection with the prosecution of such
Intellectual Property Rights; and (iii) the choice of prosecution counsel shall
be reasonably satisfactory to GENUITY. If GTE refuses to file a patent
application for protection of any such jointly owned Intellectual Property
Rights after GENUITY has requested that GTE do so, GENUITY may do so, with
counsel reasonably satisfactory to GTE, and the cost thereof shall be borne
equally by GTE and GENUITY.

         3.6. Limitations and Obligations of Ownership.

maintain and enforce any Intellectual Property Rights solely owned by such party
in such manner as such party deems appropriate in its sole discretion.

         (b) To the extent any party hereto has any right, title or interest in
or to any Intellectual Property Right that is to be owned jointly or exclusively
by the other party in accordance with the terms of this Section 0, such first
party shall assign, and hereby assigns, to such other party such portion or all
of the first party's right, title and interest in and to such Intellectual
Property Right as required hereunder. The first party shall execute and procure
such documents and take such other actions as may be reasonably requested from
time to time by the other party to obtain for its own benefit such Intellectual
Property Rights or otherwise to transfer or confirm its Intellectual Property
Rights.

         (c) For any and all jointly owned Intellectual Property Rights, subject
to the obligations of Confidentiality set forth in Section 0 hereof:

                  (i) Each party shall have an undivided joint interest with the
         other party in and to all such jointly owned Intellectual Property
         Rights.

                  (ii) Each party shall have the right to license or sublicense
         jointly owned Intellectual Property Rights without any duty to account
         to the other party.

                  (iii) Each party shall have the right to exercise or otherwise
         exploit jointly owned Intellectual Property Rights (including, without
         limitation, the right to make, use, offer for sale, sell, and make
         versions, adaptations and derivatives works), by any manner and means
         now known or hereafter devised, in perpetuity, without any duty to
         account to the other party.

                  (iv) Each party shall obtain waivers of any and all claims
         against the other party that any employee, subcontractor or agent of
         such party may now or hereafter have in any jurisdiction under "moral
         rights" or rights of "droit moral" encompassed by any jointly owned
         Intellectual Property Rights, and to the extent that such rights may
         not be waived, each such party shall secure covenants and stipulations
         of those individuals not to assert such rights against any of the other
         parties hereto or their respective successors, assigns, licensees and
         sublicensees.

                  (v) If either party becomes aware of any infringement, misuse
         or misappropriation of any jointly owned Intellectual Property Right,
         or any attempt to invalidate any jointly owned Intellectual Property
         Right, such party shall promptly notify the other party, and the
         parties shall thereafter confer in good faith regarding the steps, if
         any, that should be taken to remedy any such infringement, misuse or
         misappropriation or any such invalidity attempt. Either party shall
         have the right, at its sole discretion and expense, to enforce any
         jointly owned Intellectual Property Right against a third party. The
         other party shall reasonably cooperate in any such proceeding;
         provided, however, that the party bringing such proceeding shall
         reimburse the other party for such other party's costs and reasonable
         expenses, including reasonable attorneys fees, incurred in connection
         with such cooperation; and provided, further, that the duty of
         cooperation shall not interfere or diminish in any way with the right
         of such other party to grant licenses hereunder, including licenses to
         the accused infringer, and otherwise exploit all of such other party's
         rights in the jointly owned Intellectual Property Right.

before the Effective Date, GTE hereby grants to GENUITY a worldwide,

the right to sublicense.

         (b) Negation of Licenses in Other Intellectual Property. Except and to
the extent expressly set forth in a separate written agreement between GTE and

         4.3. Limitations and Obligations of Licensees.

Intellectual Property Rights licensed to such party hereunder.

         (b) If a party becomes aware of any infringement, misuse or
misappropriation of any Intellectual Property Rights of the other party licensed
to the first party hereunder, the first party shall notify the other party with
a commercially reasonable period of time and shall cooperate reasonably with the
other party, at the other party's request and expense, to terminate or remedy
such infringement, misuse or misappropriation.

party to obtain, maintain or enforce Intellectual Property Rights licensed to

5. Other Limitations on Ownership and Licenses.

         5.1. Prior Obligations. All rights in or to Intellectual Property
Rights granted by either party hereunder by assignment, license or otherwise,
are subject to any rights granted to any third party in such Intellectual
Property Rights as of the Effective Date hereof.

         5.2. Third Party Intellectual Property. Each party acknowledges that,
in order to exercise any rights granted hereunder, including but not limited to
Jointly-Owned Non-Statutory Intellectual Property, it may need to license or
otherwise obtain rights to use Third Party Intellectual Property. Such licenses
or other rights shall be at such party's sole cost and expense and the party
obtaining such licenses or other permissions shall be solely responsible for
observing and complying with the terms and conditions under which such Third
Party Intellectual Property is licensed or right is otherwise obtained from the
applicable third party.

6. Warranties.

         6.1. 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 in this Agreement.

         6.2. No Conflicts. Each party warrants that, to the best of its
knowledge, it owns, or otherwise has the necessary rights in the Intellectual
Property Rights to assign ownership or to grant the rights and licenses conveyed
herein.

         6.3. Disclaimer. THE WARRANTIES IN THIS SECTION 0 ARE IN LIEU OF ALL
OTHER WARRANTIES, EXPRESS OR IMPLIED, WHETHER ARISING BY COURSE OF DEALING OR
PERFORMANCE, CUSTOM, USAGE IN THE TRADE OR PROFESSION OR OTHERWISE, INCLUDING
BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, TITLE AND FITNESS FOR
A PARTICULAR PURPOSE OR WARRANTIES AGAINST INFRINGEMENT. WITHOUT LIMITING THE
FOREGOING, EACH PARTY EXPRESSLY DISCLAIMS ANY EXPRESS OR IMPLIED WARRANTY OR
REPRESENTATION (i) THAT THE EXERCISE OR OTHER EXPLOITATION OF ANY INTELLECTUAL
PROPERTY RIGHTS ASSIGNED OR LICENSED BY IT HEREUNDER SHALL BE FREE FROM
INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL PROPERTY, AND (ii) OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE EVEN IF EITHER PARTY HAS
BEEN ADVISED OR SHOULD HAVE KNOWN OF SUCH PURPOSE. Except for the warranties
expressly set forth in this Section 0, each of the parties acknowledges and
agrees that it has relied on no other representations or warranties and that no
other representations or warranties have formed the basis of its bargain
hereunder.

7. Limitation of Liability

         EXCEPT FOR BREACH BY THE LICENSEE OF THE LIMITATIONS AND RESTRICTIONS
ON THE RIGHTS GRANTED UNDER THE INTELLECTUAL PROPERTY RIGHTS OF THE LICENSOR,
NEITHER PARTY BE ENTITLED TO RECOVER FROM THE OTHER PARTY ANY INCIDENTAL,
CONSEQUENTIAL, INDIRECT, SPECIAL OR PUNITIVE DAMAGES (INCLUDING, WITHOUT
LIMITATION, DAMAGES FOR LOSS OF BUSINESS, LOSS OF PROFITS OR LOSS OF USE),
WHETHER BASED ON CONTRACT, TORT (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE), OR
ANY OTHER CAUSE OF ACTION RELATING TO INTELLECTUAL PROPERTY RIGHTS ASSIGNED OR
LICENSED HEREUNDER OR CONFIDENTIAL INFORMATION, OR OTHERWISE RELATING TO THIS
AGREEMENT, EVEN IF THE OTHER PARTY HAS BEEN INFORMED OR SHOULD HAVE KNOWN OF THE
POSSIBILITY OF SUCH DAMAGES.

8. Confidential Information.

         8.1. Restrictions. The Confidential Information of the disclosing party
may be used by the receiving party only for the performance of its obligations
and the exercise of its rights hereunder and may only be disclosed to those
employees, subcontractors or agents of the receiving party who have a need to
know in order so to perform or exercise. Except and to the extent set forth in
Section 0, the receiving party may not disclose Confidential Information of the
disclosing party to any other person, entity or the public without the prior
written consent of the disclosing party; provided, however, that such
Confidential Information may be disclosed by the receiving party without the
necessity of prior written consent to the receiving party's employees,
subcontractors or consultants who require access to such Confidential
Information to perform the receiving party's obligations or to exercise its
rights hereunder; provided, however, such persons have entered into written
agreements which contain obligations of nondisclosure and nonuse no less
restrictive than set forth in this Section 0, which agreements shall be
enforceable by the disclosing party.

         8.2. Compliance with Governmental, Judicial Requirements. If a
receiving party receives a request to disclose any Confidential Information of
the disclosing party (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, the receiving party agrees that, prior to
disclosing any Confidential Information of the disclosing party, it shall (i)
notify the disclosing party of the existence and terms of such request or
advice, (ii) cooperate with the disclosing party in taking legally available
steps to resist or narrow any such request or to otherwise eliminate the need
for such disclosure at the disclosing party's sole expense, if requested to do
so by the disclosing party, and (iii) if disclosure is required, it shall be the
obligation of the disclosing party 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 the disclosing
party as is required to be disclosed.



                                       10
<PAGE>

         8.3. Continuing Obligation. The obligation of nondisclosure and nonuse
with respect to Confidential Information of the disclosing party shall survive
and continue for a period of five (5) years after the Effective Date; provided,
however, that the obligations of non-disclosure and non-use shall continue in
perpetuity for software in any form.

9. Dispute Resolution.

         9.1. 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 as set forth below.

         9.2. 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 sixty (60) days before initiating an action in the
appropriate jurisdiction; provided, however, that each party reserves the right
to pursue and defend its rights in court after the said sixty (60) day period.

         9.3. 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.

10. General.

         10.1. Notice. Any written notice either party may give the other
concerning the subject matter of this Agreement shall be in writing and given or
made by means that obtain a written acknowledgment of receipt. Notices shall be
sent to the parties at the following addresses, which may be changed by written
notice:

                                  To GTE:
                                          ----------------------------------

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

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

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


                              To GENUITY:
                                          ----------------------------------

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

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

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



        Notice shall be deemed to have been given or made when actually
received, as evidenced by written acknowledgment of receipt.

         10.2. Compliance. GTE and GENUITY shall each comply with the provisions
of all applicable federal, state, and local laws, ordinances, regulations and
codes (including, without limitation, procurement of required permits or
certificates) in fulfillment of their obligations under this Agreement. All
Intellectual Property Rights Held by either party are subject to U.S. export and
foreign transactions control regulations. Each party undertakes that it shall
neither export, nor cause nor permit to be exported, without the other party's
prior written consent and without compliance with applicable law and regulation,
any such Intellectual Property Rights of the other party out of the United
States of America, nor shall such rights be made available by such party,
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. Each party 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.

         10.3. Assignment, Subcontracting. Neither this Agreement nor any rights
or obligations hereunder shall be assignable by either of the parties without
the other party's prior written consent; provided, however, that each party may
assign this Agreement to any Affiliate or to any purchaser of any of such party
or of such party's business to which such license relates upon the sale of all
or substantially all of the assets of such business or upon a merger, stock swap
or other means by which a third party acquires that part of such party's
business to which such license relates. Any attempted or purported assignment in
violation of the foregoing shall be void. Subject to the foregoing, this
Agreement shall be binding upon and inure to the benefit of the successors and
permitted assigns of each party hereto.

         10.4. 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.



                                       12
<PAGE>

         10.5. 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.

         10.6. 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.

         10.7. 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.

         10.8. Force Majeure. If performance of any obligations by either party
under this Agreement 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.

         10.9. 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 attached
hereto.

         The Base Rent (at the rates specified in Section 1.2 hereof) and
Additional Rent (sometimes referred to herein, collectively, as "Rent") shall be
payable by Tenant to Landlord at the Payment Address or such other place as
Landlord may from time to time designate by notice to Tenant without any demand

         (a) Beginning on the Commencement Date, Base Rent shall be payable in
advance on the first day of each and every calendar month during the Lease Term.
If the Commencement Date falls on a day other than the first day of a calendar
month, the first payment which Tenant shall make shall be made on the

only for the purposes specified as the Permitted Use thereof in Section 1.2 of
this Lease, and for no other purpose or purposes without the Landlord's consent,
which consent shall not be unreasonably withheld, delayed or conditioned.

         The Tenant shall comply and shall cause its employees, agents, and
invitees to comply with such reasonable rules and regulations as Landlord shall
from time to time establish for the proper regulation of the Building and the
Lot, provided that Landlord gives Tenant reasonable advance notice thereof and
that such additional rules and regulations shall be of general application to
all the tenants in the Building.

5.2      COMPLIANCE WITH LAWS

         Tenant agrees that no trade or occupation shall be conducted in the
Premises or use made thereof which will be unlawful, improper, or contrary to
any law, ordinance, by-law, code, rule, regulation or order applicable in the
municipality in which the Premises are located or which will disturb the quiet
enjoyment of any other tenants of the Building. Tenant shall obtain any and all
approvals, permits, licenses, variances and the like from governmental or
quasi-governmental authorities, including without limitation any Architectural
Access Board and Board of Fire Underwriters (collectively, "Approvals") which
are required for Tenant's particular use of the Premises, including, without
limitation, any which may be required for any construction work and
installations, alterations, or additions made by Tenant to, in, on, or about the
Premises. Tenant shall not be responsible for compliance with any such laws,
regulations, or the like requiring (i) structural repairs or modifications, or
(ii) repairs or modifications to the utility or building service equipment
located outside of or not exclusively serving the Premises, or (iii)
installation of new building service equipment, such as fire detection or
suppression equipment, unless such repairs, modifications, or installations are
required (a) due to Tenant's work, alterations, or repairs in the Premises or
Tenant's particular manner of use of the Premises (as opposed to office use,
generally), or (b) due to the negligence or willful misconduct of Tenant or any
agent, employee, or contractor of Tenant. Tenant shall not place a load upon any
floor in the Premises exceeding the lesser of (a) the floor load per square foot
of area which such floor was designed to carry as certified by Landlord's
architect and (b) the floor load per square foot of area which is allowed by
law. Landlord reserves the right to prescribe the weight and position of all
business machines and mechanical equipment, including safes, which shall be
placed so as to distribute the weight.

5.3      INSURANCE RISKS

         Tenant shall not permit any use of the Premises which will make
voidable or, unless Tenant pays the extra insurance premium attributable thereto
as provided below, increase the premiums for any insurance on the Building or on
the contents of said property or which shall be contrary to any law or
regulation from time to time established by the applicable Fire Insurance Rating
Association or which shall require any alteration or addition to the Building.
Landlord acknowledges that the use of the Premises for the Permitted Uses shall
not result in any violation by Tenant of the terms of this paragraph.

5.4      ELECTRICAL EQUIPMENT

         The Tenant shall not, without Landlord's written consent in each

         (b)      Negative Covenants

                  In regard to the use and occupancy of the Premises and any
common areas, Tenant will not: (1) place or maintain any trash, refuse or other
articles in any vestibule or entry of the Premises, on the sidewalks or

accumulations of or burn garbage, trash, rubbish or other refuse within or
without the Premises; (3) cause or permit objectionable odors to emanate or to

to the loading docks serving the Building, except when Tenant is actively using
such loading docks.

         Except as expressly permitted in this Section 5.6, Tenant shall not
place any signs, placards, or the like on the Building or in the Premises that
will be visible from outside the Premises (including without limitation both
interior and exterior surfaces of windows) without the approval of Landlord.
Tenant shall have signage rights in any building directory as well as
appropriate floor and door signage. Subject to Tenant obtaining all necessary
approvals and permits therefor, Tenant shall have exterior signage rights
consistent with the exterior signage existing at the Premises as of the
Commencement Date. Plans and specifications, including, without limitation,
artwork, for such signage must be submitted to Landlord for its written approval
before installation, which approval shall not be unreasonably withheld. In any
event, the total area of Tenant's exterior signage shall not exceed that
proportion of the total area of exterior signage allowed on the Building under
applicable zoning regulations that the floor area of the Premises bears to the
total floor area of the Building. The Tenant shall comply at its own expense
with the requirements of all laws and regulations affecting the maintenance of
Tenant's signage. Tenant shall remove all signs upon termination of this Lease
and shall return the Premises and the Building to their condition prior to the
placement or erection of said signs.

5.7      HAZARDOUS MATERIALS

         The Tenant shall not use, handle, store or dispose of any oil,
hazardous or toxic substances, materials or wastes (collectively "Hazardous
Materials") in, under, on or about the Property except for (a) such storage and
use consented to by Landlord in advance which consent may be withheld in
Landlord's sole and absolute discretion, and (b) reasonable quantities of
cleaning fluids and substances associated with normal office uses, all of which
shall be used, stored, handled, and disposed of strictly in accordance with all
applicable laws, regulations, and orders of public authorities. Any Hazardous
Materials in the Premises, and all containers therefor, shall be used, kept,
stored and disposed of in conformity with all applicable laws, ordinances,
codes, rules, regulations and orders of governmental authorities. If the
transportation, storage, use or disposal of Hazardous Materials anywhere on the
Property by Tenant results in (1) contamination of the soil or surface or ground
water, or (2) loss or damage to person(s) or property, then Tenant agrees (i) to
notify Landlord immediately of any contamination, claim of contamination, loss
or damage, (ii) after consultation with and approval by Landlord, to clean up
all contamination in full compliance with all applicable statutes, regulations
and standards, and (iii) to indemnify, defend and hold Landlord harmless from
and against any claims, suits, causes of action, costs and fees, including,
without limitation, attorneys' fees, arising from or connected with any such
contamination, claim of contamination, loss or damage. This provision shall
survive the termination of this Lease. No consent or approval of Landlord shall
in any way be construed as imposing upon Landlord any liability for the means,
methods, or manner of removal, containment or other compliance with applicable
law for and with respect to the foregoing. The terms of this Section 5.7 shall
apply to any transportation, storage, use or disposal of Hazardous Materials
irrespective of whether Tenant has obtained Landlord's consent therefor but
nothing in this Lease shall limit or otherwise modify the requirement of
obtaining Landlord's prior consent as set forth in the first sentence of this
Section 5.7.

6.1      INSTALLATIONS, ALTERATIONS, AND ADDITIONS

         Tenant shall not make structural installations, alterations, or
additions to the Premises, but may make nonstructural installations, alterations
or additions provided the materials and workmanship are of equivalent (or
better) quality than the existing improvements and will not affect the utility
or building service systems or equipment. Any installations, alterations, or
additions made by Tenant shall be at Tenant's sole cost and expense and shall be
done in a good and workmanlike manner and in compliance with the requirements of
Section 5.2. Prior to Tenant's use of the Premises after the performance of any
such work, Tenant shall procure certificates of occupancy and any other required
certificates. Tenant shall not suffer or permit any mechanics' or similar liens
to be placed upon the Premises for labor or materials furnished to Tenant or
claimed to have been furnished to Tenant in connection with work of any
character performed or claimed to have been performed at the direction of
Tenant, and shall cause any such lien to be released of record without cost to
Landlord. At all times when any installation, alteration, or addition by Tenant

insurance evidencing such coverage shall be furnished to Landlord prior to the
commencement of any such work. Any installations, alterations or additions made
by Tenant (and permanently attached) to the Premises other than movable personal

                            ASSIGNMENT AND SUBLETTING

7.1      PROHIBITION

         Notwithstanding any other provision of this Lease, Tenant shall not,
directly or indirectly, assign, mortgage, pledge or otherwise transfer,
voluntarily or involuntarily, this Lease or any interest herein or sublet (which
term without limitation, shall include granting of concessions, licenses, and
the like) or allow any other person or entity to occupy the whole or any part of
the Premises, without, in each instance, having first received the express
consent of Landlord, which consent may be withheld in Landlord's sole
discretion. Any assignment of this Lease or subletting of the whole or any part
of the Premises (other than as permitted to a subsidiary or a controlling
corporation as set forth below) by Tenant without Landlord's express consent
shall be invalid, void and of no force or effect. This prohibition includes,
without limitation, any assignment, subletting, or other transfer which would
occur by operation of law, merger, consolidation, reorganization, acquisition,
transfer, or other change of Tenant's corporate or proprietary structure,
including a change in the partners of any partnership, and the sale, pledge, or
other transfer of any of the issued or outstanding capital stock of any
corporate Tenant (unless such stock is publicly traded on a recognized security
exchange or over-the-counter market).

         The requirement of Landlord's prior consent shall not, however, be
applicable to an assignment of this Lease by Tenant to an entity controlling,
controlled by, or under common control with, Tenant provided (and it shall be a
condition of the validity of any such assignment) that such subsidiary or
controlling corporation agree directly with Landlord to be bound by all of the
obligations of Tenant hereunder, including, without limitation, the obligation
to pay the Rent and other amounts provided for under this Lease, the covenant to
use the Premises only for the purposes specifically permitted under this Lease
and the covenant against further assignment (except as otherwise permitted
hereby); but such assignment shall not relieve Tenant herein named of any of its
obligations hereunder, and Tenant shall remain fully liable therefor. Further,
Landlord's consent shall not be required for an assignment of this Lease in
connection with a transfer of substantially all operations of Tenant to another
entity by way of merger, consolidation or sale of substantially all of the stock
therein or assets thereof. The initial offering of stock in Tenant (or in
Tenant's parent) to the public or the subsequent sale of such stock on a
nationally recognized stock exchange shall not be deemed an assignment or
transfer under this Article VII.

7.2      ACCEPTANCE OF RENT FROM TRANSFEREE

         The acceptance by Landlord of the payment of Rent, or other charges
following assignment, subletting, or other transfer prohibited by this Article
VII shall not be deemed to be a consent by Landlord to any such assignment,
subletting, or other transfer, nor shall the same constitute a waiver of any
right or remedy of Landlord.

8.1      TENANT OBLIGATIONS

         From and after the date that possession of the Premises is delivered to
Tenant and until the end of the Lease Term, Tenant shall keep the interior,
non-structural portions of the Premises in good order, condition, and repair,
reasonable wear and tear and damage by casualty, as a result of condemnation, or
as a result of the negligence or willful misconduct of Landlord, its agents,
employees or contractors excepted; and shall return the Premises to Landlord at
the expiration or earlier termination of the Lease Term in such condition.

8.2      LANDLORD OBLIGATIONS

         Except as may be provided in Articles XII and XIII, Landlord agrees to
keep in good order, condition, and repair the structural components (including
the exterior walls) of the Premises and the Building, and the roof of the
Building, any common utility and Building systems (including HVAC), any common
hallways, entrances, restrooms and elevators and the Lot (including all parking

                      SERVICES TO BE FURNISHED BY LANDLORD;
                                    UTILITIES

9.1      LANDLORD'S SERVICES

         The Landlord shall provide all necessary utilities to the Building (to
the extent such service is provided to the Building as of the Commencement
Date). To the extent Tenant requires HVAC services after normal business hours
(as hereinafter defined), Landlord shall provide such services and Tenant shall
reimburse Landlord for the cost of such services at the prevailing market rate
as determined by Landlord from time to time in its reasonable discretion.
Business hours for the Building shall be _____ a.m. to ______ p.m., Monday
through Friday and _____ a.m. to _____ p.m. on Saturdays; provided, however,
Tenant shall have access to the Premises twenty-four (24) hours per day, seven
(7) days per week. Landlord shall provide hot and cold water, heating and
cooling and regular cleaning and maintenance of all common areas of the Building
and any parking and pedestrian areas outside the Building. Tenant shall be
responsible for providing janitorial services to the Premises at its sole cost
and expense.

9.2      FORCE MAJEURE

         Neither Landlord nor Tenant shall be liable for its delay in performing
any of its respective obligations under this Lease (excluding any financial
obligations) to the extent such delay results from causes beyond its reasonable
control, including without limitation labor dispute, breakdown, accident, order
or regulation of or by any governmental authority, or failure of supply, or
inability by the exercise of reasonable diligence to obtain supplies, parts, or
employees necessary to furnish services required under this Lease, or because of
war or other emergency, or for any cause due to any act, neglect, or default of
the other party, and in no event shall either Landlord or Tenant ever be liable
to the other for any indirect, special or consequential damages under the
provisions of this Section 9.2 or any other provision of this Lease. If there is
an interruption of utility service or other building services to the Premises
due to the negligence or willful misconduct of Landlord or its agents,
employees, or contractors that renders all or any portion of the Premises
untenantable for the Permitted Use hereunder, and such interference shall
continue following notice to Landlord, the Rent shall proportionately abate
until such services are restored. The proportionate abatement of Rent set forth
in the immediately preceding sentence shall be Tenant's sole and exclusive
remedy and Landlord shall not be liable for any other loss or damage resulting
from an interruption of utility service or other building services unless such
interruption is due to the gross negligence or willful misconduct of Landlord.

separately metered and directly billed utility costs and expenses pertaining to
extraordinary utility requirements of Tenant for portions of the Premises (e.g.,
a data room). To the extent any such extraordinary utility costs and expenses
cannot be separately metered, Tenant shall pay its reasonable allocable share of
such charges based upon the rentable square footage of that portion of the
Premises subject to such extraordinary usage (taking into account any
extraordinary usage by Landlord).

                                    INDEMNITY

10.1     THE TENANT'S INDEMNITY

         Tenant shall indemnify and save harmless Landlord, and the directors,
officers, agents and employees of Landlord, against and from all claims,
expenses or liabilities in connection with damage to property or injury to
person to the extent (a) arising directly or indirectly from any default or
breach by Tenant or Tenant's contractors, licensees, agents, servants, or
employees under any of the terms or covenants of this Lease; or (b) arising from
any accident, injury, or damage to any person or property, on or upon the
Premises; or (c) arising from any accident, injury, or damage to any person or
property occurring outside the Premises but within the Building or on the Lot,
where such accident, injury or damage results from any act, omission or
negligence on the part of Tenant or Tenant's contractors, licensees, agents,
servants or employees: provided, however, that in no event shall Tenant be
obligated under this Section 10.1 to indemnify Landlord, the directors,
officers, agents or employees of Landlord to the extent such claim, expense or
liability results from the negligence or willful misconduct of Landlord or the
officers, agents, contractors or employees of Landlord.

         This indemnity and hold harmless agreement shall include, without
limitation, indemnity against all expenses, attorneys' fees and liabilities
incurred in connection with any such claim or proceeding brought thereon and the
defense thereof with counsel reasonably acceptable to Landlord. At the request
of Landlord, Tenant shall defend any such claim or proceeding directly on behalf
and for the benefit of Landlord.

10.2     THE LANDLORD'S INDEMNITY

         Landlord shall indemnify and save harmless Tenant, and the directors,
officers, agents and employees of Tenant against and from all claims, expenses
or liabilities in connection with damage to property or injury to person to the
extent (a) arising directly or indirectly from any default or breach by Landlord
or Landlord's contractors, licensees, agents, servants or employees under any of
the terms or covenants of this Lease; or (b) arising from any accident, injury
or damage to any person or property, on or upon the Building or the Lot
(excluding the Premises); or (c) arising from any accident, injury or damage to
any person or property occurring within the Premises where such accident, injury
or damage results from any act, omission or negligence on the part of Landlord
or Landlord's contractors, licensees, agents, servants or employees; provided,
however, that in no event shall Landlord be obligated under this Section 10.2 to
indemnify Tenant, the directors, officers, agents or employees of Tenant to the
extent such claim, expense or liability results from the negligence or willful
misconduct of Tenant or the officers, agents, contractors or employees of
Tenant.

         This indemnity and hold harmless agreement shall include, without
limitation, indemnity against all expenses, attorneys' fees and liabilities
incurred in connection with any such claim or proceeding brought thereon and the
defense thereof with counsel reasonably acceptable to Tenant. At the request of
Tenant, Landlord shall defend any such claim or proceeding directly on behalf
and for the benefit of Tenant.

10.3     INJURY CAUSED BY THIRD PARTIES

         Tenant agrees that Landlord shall not be responsible or liable to
Tenant, or to those claiming by, through, or under Tenant, for any loss or
damage resulting to Tenant or those claiming by, through, or under Tenant, or
its or their property, that may be occasioned by or through the acts or
omissions of persons other than Landlord, or for any loss or damage from the
breaking, bursting, crossing, stopping, or leaking of electric cables and wires,
and water, gas, sewer, or steam pipes, or like matters not resulting or arising
from the gross negligence or intentional acts of Landlord.

10.4     SECURITY

         Tenant may, at its own expense, provide its own security to the
interior of the Premises, including its own locks to an area ("Secured Area")
within the Premises. Tenant need not furnish Landlord with a key but upon the
Termination Date, Tenant shall surrender all such keys to Landlord. If Landlord
must gain access to a Secured Area in a non-emergency situation, Landlord shall
contact Tenant and Landlord and Tenant shall arrange a mutually agreed upon time
for Landlord to do so. Landlord shall comply with all reasonable security
measures pertaining to the Secured Area. If Landlord determines in its sole
discretion that an emergency in the Building or the Premises, including, without
limitation, a suspected fire or flood, requires Landlord to gain access to the
Secured Area, Tenant hereby authorizes Landlord to forcibly enter the Secured
Area. In such event, Landlord shall have no liability whatsoever to Tenant, and
Tenant shall pay all reasonable expenses incurred by Landlord in repairing or
reconstructing any entrance, corridor, door or other portions of the Premises
damaged as a result of a forcible entry by Landlord. Landlord shall be
responsible for providing exterior security to the Building, and for maintaining
the card access system in and to the Building on the same basis as Landlord
provides these security services to its own premises in the immediate vicinity
of the Building; however, Landlord does not warrant security services against
intrusion, loss, property damage, vandalism or injury to employees, visitors or
contractors ("Damages"), and Landlord shall not be liable for any Damages based
on a claim of inadequate or ineffective security or breach of Landlord's
obligation to provide security services as set forth herein.

                                    INSURANCE

11.1     PUBLIC LIABILITY INSURANCE

         The Tenant agrees to maintain in full force from the date upon which
Tenant first enters the Premises for any reason, throughout the Lease Term, and
thereafter so long as Tenant is in occupancy of any part of the Premises, (a) a
policy of commercial general liability insurance, written on an occurrence basis
and including contractual liability coverage to cover any liabilities assumed
under this Lease, including products liability, and completed operations
liability, and (b) automobile liability insurance covering all owned vehicles,
hired vehicles, and all other non-owned vehicles. Each such policy shall
designate Tenant as a named insured and Landlord and any mortgagees (as may be
set forth in a notice given from time to time by Landlord) shall be named as
additional insureds, as their interests appear.

         Each such policy shall expressly provide that it shall not expire or be
amended or canceled without at least thirty (30) days' prior written notice to
Landlord in each instance and that the interests of Landlord thereunder or
therein shall not be affected by any breach by Tenant of any policy provision,
and a duplicate original or certificate thereof shall be delivered to Landlord.
The minimum limits of liability of such insurance shall be bodily injury and
property damage combined single limit of $3,000,000 per occurrence.

         Landlord shall carry liability insurance covering all common areas of
the Building and the Lot. The liability insurance shall include contractual
liability coverage so that Landlord's indemnity and other applicable obligations
will be passed on to the insurance company.

11.2     HAZARD INSURANCE

         The Tenant agrees to maintain in full force from the date upon which
Tenant first enters the Premises for any reason, throughout the Lease Term, and
thereafter so long as Tenant is in occupancy of any part of the Premises, a
policy insuring any leasehold improvements paid for by Tenant and all fixtures,
equipment, and other personal property of Tenant against damage or destruction
by fire or other casualty in an amount equal to the full replacement cost of
such property. Any insurance policy required of the Tenant may be maintained by
means of a policy or policies of blanket insurance, covering additional items or
locations, and any such policy may provide for such commercially reasonable
deductible limits as Tenant deems appropriate.



                                       14
<PAGE>

         Notwithstanding the foregoing, Tenant shall be permitted to self-insure
its fixtures, equipment and other personal property from time to time located
in, on or about the Premises, and all leasehold improvements to the Premises
constructed or installed by Tenant, provided that at all times when Tenant so
self-insures the same or any portion thereof, Tenant's net worth shall be and
remain at least Fifty Million and 00/100 Dollars ($50,000,000.00). During all
periods in which Tenant so self-insures any of the same, the rights and
obligations of Landlord and Tenant shall remain the same as if Tenant shall have
purchased and kept in force thereon insurance from an independent, institutional
insurer of recognized responsibility, and, without limitation, the provisions of
Sections 10.2 and 11.5 of this Lease shall remain in full force and effect. The
Tenant represents, by so self-insuring, that Tenant then is financially able to
absorb any loss thereto without significant reduction of available capital or
any other material, adverse effect on Tenant or its business operations, and
that Tenant then is of at least such minimum net worth.

         Landlord shall maintain in full force from the date upon which Tenant
first enters the Premises for any reason, throughout the Lease Term, and
thereafter so long as Tenant is in occupancy of any part of the Premises, a
policy of insurance upon the Building insuring against all risks of physical
loss or damage under an All Risk coverage endorsement in an amount at least
equal to the full replacement value of the property insured, with an Agreed
Amount endorsement to satisfy co-insurance requirements, as well as insurance
against breakdown of boilers and other machinery as customarily insured against.
Upon request of Tenant from time to time, a certificate of such insurance shall
be delivered to Tenant.

11.3     CONSTRUCTION PERIOD INSURANCE

         At any time when demolition or construction work is being performed on
or about the Premises or Building by or on behalf of Tenant, the Tenant shall
keep in full force and effect the following insurance coverage:

         (1) builder's risk completed value (non-reporting form) in such form
and affording such protections as required by Landlord, naming Landlord and its
mortgagees as additional insureds; and

         (2) workers' compensation or similar insurance in form and amounts
required by law.

         Tenant shall cause a certificate or certificates of such insurance to
be delivered to Landlord prior to the commencement of any work in or about the
Building or the Premises, in default of which Landlord shall have the right, but
not the obligation, to obtain any or all such insurance at the expense of
Tenant, in addition to any other right or remedy of Landlord. The provisions of
this Section 11.3 shall survive the expiration or earlier termination of this
Lease.




                                       15
<PAGE>

11.4     WAIVER OF SUBROGATION

         Insofar as, and to the extent, that the following provisions may be
effective without invalidating or making it impossible to secure insurance
coverage from responsible insurance companies doing business in the Commonwealth
of Massachusetts (even though extra premium may result therefrom): Landlord and
Tenant mutually agree that with respect to any loss which is covered by
insurance then being carried by them (or which is required to be carried
pursuant to this Lease), the one carrying or required to carry such insurance
and suffering said loss shall release the other of and from any and all claims
with respect to such loss; and they further mutually agree that their insurance
companies shall have no right of subrogation against the other on account
thereof. If, at the written request of one party, this release and
non-subrogation provision is waived, then the obligation of reimbursement shall
cease for such period of time as such waiver shall be effective, but nothing
contained in this Section 11.4 shall be deemed to modify or otherwise affect any
releases elsewhere contained in this Lease.


                                   ARTICLE XII
                                    CASUALTY

12.1     DEFINITION OF "SUBSTANTIAL DAMAGE" AND "PARTIAL DAMAGE"

         The term "substantial damage," as used herein, shall refer to damage
which results in damage to at least thirty percent (30%) of the replacement cost
of the Building. Any damage which is not "substantial damage" is "partial
damage."

12.2     PARTIAL DAMAGE TO THE BUILDING

         If during the Lease Term there shall be partial damage to the Building
by fire or other casualty, Landlord shall promptly proceed to restore the
Building to the condition in which it was immediately prior to the occurrence of
such damage.

12.3     SUBSTANTIAL DAMAGE TO THE BUILDING

         If during the Lease Term there shall be substantial damage to the
Building by fire or other casualty, Landlord shall promptly restore the Building
to the extent reasonably necessary to enable Tenant's use of the Premises,
unless Landlord, within ninety (90) days after the occurrence of such damage,
shall give notice to Tenant of Landlord's election to terminate this Lease. If
Landlord shall give such notice, then this Lease shall terminate as of the date
of such notice with the same force and effect as if such date were the date
originally established as the expiration date hereof.



                                       16
<PAGE>

12.4     ABATEMENT OF RENT

         If during the Lease Term the Building or the Premises shall be damaged
by fire or casualty and if such damage shall materially interfere with Tenant's
use of the Premises as contemplated by this Lease, a just proportion of the Rent
payable by Tenant hereunder shall abate proportionately for the period in which,
by reason of such damage, there is such interference with Tenant's use of the
Premises, but such abatement or reduction shall end when Landlord shall have
substantially restored the Premises or so much thereof as shall have been
originally constructed by Landlord (exclusive of any of Tenant's fixtures,
furnishings, equipment and the like or work performed therein by Tenant) to the
condition in which the Premises were prior to such damage.


                                  ARTICLE XIII
                                 EMINENT DOMAIN

13.1     RIGHTS OF TERMINATION FOR TAKING

         If the Premises, or such portion thereof as to render the balance (if
reconstructed to the maximum extent practicable in the circumstances) physically
unsuitable for Tenant's purposes, shall be taken (including a temporary taking
in excess of 180 days) by condemnation or right of eminent domain or sold in
lieu of condemnation, Landlord or Tenant may elect to terminate this Lease by
giving notice to the other of such election not later than thirty (30) days
after Tenant has been deprived of possession.

         Further, if so much of the Building (which may include the Premises) or
the Lot shall be so taken, condemned or sold or shall receive any direct or
consequential damage by reason of anything done pursuant to public or
quasi-public authority such that continued operation of the same would, in
Landlord's opinion, be uneconomical, Landlord may elect to terminate this Lease
by giving notice to Tenant of such election not later than thirty (30) days
after the effective date of such taking. Landlord shall only have the right to
terminate this Lease if Landlord simultaneously terminates the leases of all
other tenants of the Building similarly affected by such condemnation or taking.

         Should any part of the Premises be so taken or condemned or receive
such damage and should this Lease be not terminated in accordance with the
foregoing provisions, Landlord shall promptly restore the Premises to an
architectural unit that is reasonably suitable to the uses of Tenant permitted
hereunder.

13.2     PAYMENT OF AWARD

         The Landlord shall have and hereby reserves and excepts, and Tenant
hereby grants and assigns to Landlord, all rights to recover for damages to the
Building and the Lot and the leasehold interest hereby created, and to
compensation accrued or hereafter to accrue by reason of such taking or damage,
as aforesaid. The Tenant covenants to deliver such further assignments and
assurances thereof as Landlord may from time to time request. Nothing contained
herein shall be construed to prevent Tenant from prosecuting in any condemnation
proceedings a claim for the value of any of Tenant's trade fixtures installed in
the Premises by Tenant at Tenant's expense and for relocation expenses.



                                       17
<PAGE>

13.3     ABATEMENT OF RENT

         In the event of any such taking of the Premises, the Rent or a fair and
just proportion thereof, according to the nature and extent of the damage
sustained, shall be suspended or abated, as appropriate and equitable in the
circumstances.


                                   ARTICLE XIV

14.1     TENANT'S DEFAULT

         (a) If at any time any one or more of the following events (herein
referred to as a "Default of Tenant") shall occur:

                  (i) Tenant shall fail to make payment of rent or any other
monetary amount due under this lease within ten (10) days after Landlord has
sent to Tenant notice of such default; or

                  (ii) Tenant shall fail to perform or observe any other
covenant or provision herein contained on Tenant's part to be performed or
observed and Tenant shall fail to remedy the same within thirty (30) days after
notice to Tenant specifying such neglect or failure, or, if such failure is of
such a nature that Tenant cannot reasonably remedy the same within such thirty
(30) day period, Tenant shall fail to commence promptly to remedy the same and
to prosecute such remedy to completion with diligence and continuity; or

                  (iii) except as otherwise provided by applicable law, if the
estate hereby created shall be taken on execution or by other process of law, or
if Tenant shall be judicially declared bankrupt or insolvent according to law,
or if any assignment shall be made of the property of Tenant for the benefit of
creditors, or if a receiver, guardian, conservator, trustee in involuntary
bankruptcy or other similar officer shall be appointed to take charge of all or
any substantial part of Tenant's property by a court of competent jurisdiction,
or if a petition shall be filed for the reorganization of Tenant under any
provisions of law now or hereafter enacted, and such proceeding is not dismissed
within sixty (60) days after it is begun, or if Tenant shall file a petition for
such reorganization, or for arrangements under any provisions of such laws
providing a plan for a debtor to settle, satisfy, or extend the time for the
payment of debts.



                                       18
<PAGE>

         (b) Tenant covenants and agrees, notwithstanding any termination of
this Lease by summary proceedings, to pay and be liable for, on the days
originally fixed herein for the payment thereof, amounts equal to the several
installments of Rent reserved as they would have become due under the terms of
this Lease if this Lease had not been terminated, and whether the Premises be
relet or remain vacant, in whole or in part, for the remainder of the Lease Term
or for a period less than the remainder of the Lease Term; but in the event the
Premises are relet by Landlord, Tenant shall be entitled to a credit in the net
amount of rent received by Landlord in reletting, after deduction of all
reasonable expenses incurred in reletting the Premises (including, without
limitation, remodeling costs, brokerage fees, attorneys' fees and the like) and
in collecting the rent in connection therewith. As an alternative, at the
election of Landlord, Tenant shall, upon such termination, pay to Landlord, as
damages, such a sum as at the time of such termination represents the present
value of the amount of the excess, if any, of the total Rent which would have
accrued to Landlord under this Lease for the remainder of the Lease Term had the
Lease not been so terminated over and above the then fair market rental value
(in advance) of the Premises for what would be the then unexpired Lease Term for
the remainder of the Lease Term had the Lease not been so terminated.

         (c) In case of any Default of Tenant and expiration and dispossession
by summary proceedings, Landlord shall use reasonable efforts to mitigate its
damages. It is specifically understood and agreed that Landlord shall be
entitled to take into account in connection with any reletting of the Premises
all relevant factors which would be taken into account by a sophisticated
developer in securing a replacement tenant for the Premises, such as, but not
limited to, the quality of the Building and the financial responsibility of any
such replacement tenant.

         (d) If there is at any time a guarantor or assignee of this Lease or
any interest of Tenant herein or any sublessee, franchisee, concessionee, or
licensee of all or any portion of the Premises, the happening of any of the
events described in paragraph (a)(iii) of this Section with respect to such
guarantor, assignee, sublessee, franchisee, concessionee, or licensee shall
constitute a Default of Tenant hereunder.

         (e) All costs and expenses incurred by or on behalf of Landlord
(including, without limitation, attorneys' fees and expenses) in enforcing its
rights hereunder or occasioned by any Default of Tenant shall be paid by Tenant.

                  Nothing contained in this Lease shall limit or prejudice the
right of Landlord to prove for and obtain in proceedings for bankruptcy,
insolvency, or like proceedings by reason of the termination of this Lease, an
amount equal to the maximum allowed by any statute or rule of law in effect at
the time when, and governing the proceedings in which, the damages are to be
proved, whether or not the amount be greater than, equal to, or less than the
amount of the loss or damages referred to above.

                        THE LANDLORD'S ACCESS TO PREMISES

15.1     THE LANDLORD'S RIGHT OF ACCESS

         The Landlord and its agents, contractors, and employees shall have the
right to enter the Premises at all reasonable hours upon reasonable advance
notice and accompanied by a representative of Tenant, except in case of
emergency, for the purpose of inspecting or of making repairs or alterations
permitted or required to be made by Landlord hereunder, and Landlord shall also
have the right to make access to the Premises available at all reasonable hours
to prospective or existing mortgagees or purchasers of any part of the Building.
Notwithstanding the foregoing, except in emergency situations as determined by
Landlord, Landlord shall exercise reasonable efforts to perform any entry into
the Premises in a manner that is reasonably designed to minimize interference
with the operation of Tenant's business in the Premises.

         For a period commencing three (3) months prior to the expiration of the
Lease Term, Landlord may have reasonable access to the Premises at all
reasonable hours for the purpose of exhibiting the same to prospective tenants.




                                   ARTICLE XVI
                              RIGHTS OF MORTGAGEES

16.1     SUBORDINATION AND ATTORNMENT

         (a) If any holder of a mortgage or holder of a ground lease of property
which includes the Premises shall so elect, the interest of Tenant hereunder
shall be subordinate to the rights of such holder, provided that such holder
shall agree to recognize in writing the rights of Tenant under this Lease upon
the terms and conditions set forth herein, and the performance by Tenant of
Tenant's obligations hereunder (but without any assumption by such holder of
Landlord's obligations under this Lease); or

         (b) If any holder of a mortgage or holder of a ground lease of property
which includes the Premises shall so elect, this Lease, and the rights of Tenant
hereunder, shall be superior in right to the rights of such holder, with the
same force and effect as if this Lease had been executed and delivered, and
recorded, or a statutory notice hereof recorded, prior to the execution,
delivery and recording of any such mortgage.

         (c) Within thirty (30) days of the date of this Lease, Tenant and the
holder of any mortgage or deed of trust affecting the Premises, or the lessor
under any ground lease affecting the Premises, shall execute and deliver to each
other an attornment agreement providing that Tenant shall attorn to such holder
or lessor in the event of a foreclosure of such mortgage or deed of trust or
transfer in lieu thereof or a termination of such ground lease and incorporating
such other terms and conditions as such party may reasonably require, provided
that such agreement includes an agreement by such other party to recognize the
rights of Tenant under this Lease and not disturb Tenant's rights hereunder.



                                       20
<PAGE>

         The Landlord agrees to use reasonable efforts to have the holder of any
such mortgage or deed of trust that may become prior to this Lease, and any such
ground lessor, as the case may be, enter into its usual nondisturbance agreement
with the Tenant, or in lieu thereof provide the Tenant with an agreement by the
terms of which such holder or ground lessor agrees to recognize the rights of
the Tenant under this Lease in the event of foreclosure of such mortgage or deed
of trust or termination of such ground lease, respectively, so long as the
Tenant is not in default hereunder.

         (d) Tenant agrees on request of Landlord to execute and deliver from
time to time any instrument that Landlord may reasonably deem necessary to
implement the provisions of this Section 16.1.

16.2     NOTICE TO MORTGAGEE AND GROUND LESSOR; OPPORTUNITY
         TO CURE

         After receiving notice from any person, firm, or other entity (or from
Landlord on behalf of any such person, etc.) that it holds a mortgage which
includes the Premises as part of the mortgaged premises, or that it is the
ground lessor under a lease with Landlord as ground lessee, which includes the
Premises as a part of the demised premises, no notice from Tenant to Landlord
shall be effective, against such holder or ground lessor unless and until a copy
of the same is given to such holder or ground lessor, and the curing of any of
Landlord's defaults by such holder or ground lessor shall be treated as
performance by Landlord. Accordingly, no act or failure to act on the part of
Landlord which would entitle Tenant under the terms of this Lease, or by law, to
be relieved of Tenant's obligations hereunder shall have such an effect unless
and until:

         (a) Tenant shall have first given written notice to such holder or
ground lessor, if any, specifying the act or failure to act on the part of
Landlord which could or would give basis to Tenant's rights; and

         (b) such holder or ground lessor, after receipt of such notice, has
failed or refused to correct or cure the condition complained of within the cure
periods provided Tenant hereunder, but nothing contained in this Section 16 or
elsewhere in this Lease shall be deemed to impose any obligation on any such
holder or ground lessor to correct or cure any such condition.

16.3     ASSIGNMENT OF RENTS.

         With reference to any assignment by Landlord of Landlord's interest in
this Lease, or the rents payable hereunder, conditional in nature or otherwise,
which assignment is made to the holder of a mortgage or ground lease on property
which includes the Premises, Tenant agrees:

      (a)     that the execution thereof by Landlord, and the acceptance thereof
              by the holder of such mortgage, or the ground lessor, shall never
              be treated as an assumption by such holder or ground lessor of any
              of the obligations of Landlord hereunder, unless such holder or
              ground lessor shall, by notice sent to Tenant, specifically
              otherwise elect; and

      (b)     that, except as aforesaid, such holder or ground lessor shall be
              treated as having assumed Landlord's obligations hereunder only
              upon foreclosure of such holder's mortgage or the taking of
              possession of the Premises, or in the case of a ground lessor, the
              assumption of Landlord's position hereunder by such ground lessor.

                            MISCELLANEOUS PROVISIONS

17.1     CAPTIONS

         The captions throughout this Lease are for convenience or reference
only and shall in no way be held or deemed to define, limit, explain, describe,
modify, or add to the interpretation, construction, or meaning of any provision
of this Lease.

17.2     BIND AND INURE

         Except as herein otherwise expressly provided, the obligations of this
Lease shall run with the land, and this Lease shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns.
Neither the assignment by Landlord of its interest in this Lease as security to
a lender holding a mortgage on the Building, nor the acceptance thereof by such
lender, nor the exercise by such lender of any of its rights pursuant to said
assignment shall be deemed in any way an assumption by such lender of any of the
obligations of Landlord hereunder unless such lender shall specifically
otherwise elect in writing or unless such lender shall have completed
foreclosure proceedings under said mortgage. Whenever the Premises are owned by
a trustee or trustees, the obligations of Landlord shall be binding upon
Landlord's trust estate, but not upon any trustee, beneficiary or shareholder of
the trust individually.

17.3     NO WAIVER

         The failure of Landlord or of Tenant to seek redress for violation of,
or to insist upon the strict performance of any covenant or condition of this
Lease shall not be deemed to be a waiver of such violation or to prevent a
subsequent act, which would originally have constituted a violation, from having
all the force and effect of an original violation. The receipt by Landlord of
Rent or additional rent with knowledge of the breach of any covenant of this
Lease shall not be deemed to be a waiver of such breach by Landlord unless such
waiver be in writing signed by Landlord. No consent or waiver, express or
implied, by Landlord or Tenant to or of any breach of any agreement or duty
shall be construed as a waiver or consent to or of any other breach of the same
or any other agreement or duty.

17.4     NO ACCORD AND SATISFACTION

         No acceptance by Landlord of a lesser sum than the minimum and
additional rent then due shall be deemed to be other than on account of the
earliest installment of such rent due, nor shall any endorsement or statement on
any check or any letter accompanying any check or payment as rent be deemed to
be an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such installment
or pursue any other remedy in this Lease or at law or in equity provided.

17.5     CUMULATIVE REMEDIES

         The specific remedies to which Landlord or Tenant may resort under the
terms of this Lease are cumulative and not intended to be exclusive of any other
remedies or means of redress to which it may be lawfully entitled in case of any
breach or threatened breach by the other party of any provisions of this Lease.
In addition to the other remedies provided in this Lease, Landlord shall be
entitled to the restraint by injunction of the violation or attempted or
threatened violation of any of the covenants, conditions or provisions of this
Lease or to a decree compelling specific performance of any such covenants,
conditions or provisions. In the event of any litigation between the parties
hereto, the unsuccessful party as determined by a court of competent
jurisdiction shall reimburse the successful party for all reasonable costs and
expenses (including attorneys' fees) in connection therewith.

17.6     PARTIAL INVALIDITY

         If any term or provision of this Lease or any portion thereof or the
application thereof to any person or circumstances shall, to any extent, be
invalid or unenforceable, then the remainder of this Lease and of such term or
provision and the application of this Lease and of such term and provision to
persons or circumstances other than those as to which it is invalid or
unenforceable, shall not be affected thereby, and each term of this Lease shall
be valid and enforceable to the fullest extent permitted by law.

17.7     ESTOPPEL CERTIFICATES

         Tenant agrees on the Commencement Date and from time to time
thereafter, within twenty (20) days' after written request by Landlord, to
execute, acknowledge and deliver to Landlord a statement in writing, certifying
that this Lease is unmodified and in full force and effect, that Tenant has no
defenses, offsets or counterclaims against its obligations to pay rent and other
charges required under this Lease and to perform its other covenants under this
Lease and that there are no uncured defaults of Landlord or Tenant under this
Lease (or, if there have been any modifications, that this Lease is in full
force and effect, as modified, and stating the modifications, and, if there are
any defenses, offsets, counterclaims or defaults, setting them forth in
reasonable detail), and the dates to which the Rent and other charges have been
paid.

17.8     BROKERAGE

         Each party hereto warrants and represents that it has dealt with no
real estate broker or agent in connection with this transaction and agrees to
defend, indemnify and save the other party harmless from and against any and all
claims for commissions or fees arising out of this Lease which, as to the
respective parties, are inconsistent with such party's warranties and
representations.

17.9     ENTIRE AGREEMENT

         All negotiations, considerations, representations, and understandings
between Landlord and Tenant are incorporated herein and this Lease expressly
supersedes any proposals or other written documents relating hereto. This Lease
may be modified or altered only by written agreement between Landlord and
Tenant.

17.10    HOLDOVER

         If Tenant remains in possession of the Premises after the termination
of this Lease without the consent of Landlord, such holding over shall not be
deemed to create any tenancy, but Tenant shall be a tenant at sufferance only,
at a daily rate equal to one hundred fifty percent (150%) of the Rent applicable
immediately prior to such termination.

17.11    COUNTERPARTS

         This Lease is executed in any number of counterparts, each copy of
which is identical, and any one of which shall be deemed to be complete in
itself and may be introduced in evidence or used for any purpose without the
production of the other copies.

17.12    CONSTRUCTION AND GRAMMATICAL USAGE

         This Lease shall be governed, construed and interpreted in accordance
with the laws of the Commonwealth of Massachusetts, and Tenant agrees to submit
to the personal jurisdiction of any court (federal or state) in Massachusetts
for any dispute, claim or proceeding arising out of or relating to this Lease.
In construing this Lease, feminine or neuter pronouns shall be substituted for
those masculine in form and vice versa, and plural terms shall be substituted
for singular and singular for plural in any place in which the context so admits
or requires. If there be more than one party tenant, the covenants of Tenant
shall be the joint and several obligations of each such party and, if Tenant is
a general partnership, the covenants of Tenant shall be the joint and several
obligations of each of the partners and the obligations of the firm.

17.13    WHEN LEASE BECOMES BINDING

         The submission of this document for examination and negotiation does
not constitute an offer to lease, or a reservation of, or option for, the
Premises, and this document shall become effective and binding only upon the
execution and delivery hereof by both Landlord and Tenant.

17.14    COVENANT OF QUIET ENJOYMENT

         Subject to the terms and provisions of this Lease and on payment of the
Rent due hereunder and compliance with all of the terms and provisions of this
Lease, Tenant shall lawfully, peaceably, and quietly have, hold, occupy, and
enjoy the Premises during the term hereof, without hindrance or ejection by any
party.

17.15    NO PERSONAL LIABILITY OF THE LANDLORD

         The Tenant agrees to look solely to Landlord's interest (including the
rents, issues and profits therefrom) in the Building and the Lot at the time
owned, or in which Landlord holds an interest as ground lessee, for recovery of
any judgment from Landlord; it being specifically agreed that neither Landlord
(whether Landlord be an individual, partnership, firm, corporation, trustee, or
other fiduciary) nor any partner, policyholder, officer, manager, member,
shareholder or director of Landlord, nor any trust of which any person holding
Landlord's interest is trustee nor any successor in interest to any of the
foregoing shall ever be personally liable for any such judgment. The covenants
of Landlord contained in this Lease shall be binding upon Landlord and
Landlord's successors only with respect to breaches occurring during Landlord's
and Landlord's successors' respective periods of ownership of Landlord's
interest hereunder.

17.16    NOTICES

         Whenever, by the terms of this Lease, notice shall or may be given
either to Landlord or to Tenant, such notice shall be in writing and shall be
delivered by hand or sent by registered or certified mail, postage prepaid or by
so-called "express" mail (such as Federal Express or U.S. Postal Service Express
Mail):

         If intended for Landlord, addressed to Landlord at the address set
forth in Section 1.2 or to such other address or addresses as may from time to
time hereafter be designated by Landlord by like notice.



                                       25
<PAGE>

         If intended for Tenant, addressed to Tenant at the address set forth on
the first page of this Lease or to such other address or addresses as may from
time to time hereafter be designated by Tenant by like notice.

         All such notices shall be effective upon delivery, attempted delivery,
or refusal, whichever occurs first, at the address or addresses of the intended
recipient, as set forth above.

17.17    SPECIAL TENANT RIGHT OF TERMINATION  [only for certain properties]

         Provided that Tenant is not in default beyond the expiration of any
applicable notice and/or cure periods. Tenant may elect to terminate this Lease
at any time by giving Landlord written notice (the "Termination Notice") of such
election at least sixty (60) days before the effective date of such termination
(the "Termination Date"), which Termination Date shall be specified in the
Termination Notice. Such termination, at Tenant's option, shall apply to either:
(i) all of the Premises without the requirement for approval by the Landlord, or
(ii) a portion of the Premises (the "Designated Portion"), provided that the
Landlord approves the location of the Designated Portion, as more particularly
set forth in the following paragraph.

         If the Tenant desires to terminate the Lease with respect to a
Designated Portion only, the Termination Notice shall describe the Designated
Portion with reasonable particularity and shall include plans depicting the
proposed separation of the Designated Portion from the remainder of the
Premises. Landlord shall respond to the Termination Notice within five (5)
business days of receipt thereof, by stating that it either approves Tenant's
plans or requests modifications thereto. If Landlord requests modifications to
Tenant's plans, it shall specify such modifications with reasonable
particularity. Tenant shall submit any revised plans so requested by Landlord
within five (5) business days after receipt of Landlord's response. If, despite
their good faith efforts, the parties cannot agree on the area of the Designated
Portion as depicted on Tenant's plans (as the same have been modified), Tenant's
Termination Notice shall be void and of no further force or effect. Landlord
shall not unreasonably withhold or condition its approval of Tenant's plans
provided that the Designated Portion as depicted by Tenant is, without
extraordinary expense, separable from the remainder of the Premises and not
unmarketable.

         Tenant shall continue to be liable for all Rent payable under this
Lease up to the Termination Date. If Tenant has effectively exercised its right
to terminate this Lease with respect to a Designated Portion only, the Rent
payable hereunder shall be adjusted as of the Termination Date as provided
below, and this Lease shall terminate on the Termination Date specified in the
Termination Notice with respect to the Designated Portion with the same force
and effect as if such date were the last day of the Lease Term. If Tenant
exercises its right to terminate this Lease with respect to all of the Premises,
this Lease shall terminate on the Termination Date with the same force and
effect as if said date were the last day of the Lease Term. The term "Premises",
as used herein, shall refer to the Premises less any Designated Portion as to
which Tenant has effectively exercised its right of termination. In the event
Tenant effectively elects to terminate this Lease with respect to a Designated
Portion, it is understood and agreed that the Designated Portion shall be
separately demisable by Landlord. In the event that Tenant exercises its
termination option with respect to a Designated Portion only, Landlord and
Tenant hereby agree that they will cooperate in connection with any
reconfiguration of any common areas and elements of the Premises that such
partial termination may necessitate.



                                       26
<PAGE>

                  In the event that Tenant effectively exercises its termination
option with respect to a Designated Portion of the Premises, any demising walls,
alterations and improvements necessary to reconfigure the premises for occupancy
by Landlord or by another occupant or tenant shall be constructed by Landlord.
Tenant shall cooperate with Landlord as necessary in connection with the
construction of any such demising walls, alterations or improvements. Within
thirty (30) days of receipt by Tenant of a bill therefor (accompanied by
reasonably detailed supporting documentation), Tenant shall pay to Landlord the
actual, out-of-pocket costs incurred by Landlord in constructing demising walls
between the Designated Portion of the Premises surrendered by Tenant and the
remainder of the Premises (as such demising walls are depicted on the plans
agreed to by Landlord and Tenant, as provided above). Tenant shall not be liable
for any incremental costs incurred by Landlord in constructing any other
improvements, additions or alterations to such surrendered space.

         If Tenant effectively exercises its termination right with respect to a
Designated Portion of the Premises, the Base Rent as set forth in Section 1.2
hereof will be reduced by an amount equal to the product of (a) the applicable
Base Rent immediately prior to the Termination Date, and (b) a fraction, the
numerator of which is the rentable square footage of the Designated Portion, and
the denominator of which is the total rentable square footage of the Premises
immediately prior to said Termination Date.

ARTICLE II:  SUBLEASE OF PREMISES

         2.1. Incorporation of Recitals: This Sublease is made subject and
subordinate to all of the terms and conditions of the Office Lease to the extent
that they relate to the Subleased Premises, except such terms as are expressly
excluded herein. Insofar as the same relate to the Subleased Premises, each and
every provision of the Office Lease except for the Excluded Provisions shall be
deemed incorporated herein and made a part of this Sublease as between Sublessor
and Sublessee, except to the extent that such provisions are inconsistent with
the provisions of this Sublease (in which event the provisions of this Sublease
shall control). Insofar as the same relate to the Subleased Premises, all
references in the Office Lease to "Landlord" (or words of similar import) shall
be deemed to refer to Sublessor and all references to "Tenant" (or words of
similar import) shall be deemed to refer to Sublessee. Provided, however, in the
event of a conflict between any provision contained in the Office Lease and a
provision contained in this Sublease, the provision contained in this Sublease
shall control as between Sublessor and Sublessee.

         2.2. Landlord's Consent or Approval. This Sublease is conditioned upon
the approval or consent of Landlord to this Sublease, to the extent and in the
form that such approval or consent is required under the Office Lease, which
approval Sublessor shall use its reasonable efforts to obtain. Sublessee agrees
to execute such documents and to take such actions as Sublessor may reasonably
request in connection with obtaining the Landlord's consent or approval to this
Sublease.

         2.3. Sublease of Subleased Premises. Sublessor hereby subleases to
Sublessee for the Sublease Term (as defined below) (a) the Subleased Premises;
(b) the right (in common with the rights of all others entitled thereto) to use
all common areas and facilities which tenants or occupants of the Office
Premises are entitled to use pursuant to the Office Lease, subject to clause (d)
below, (c) the common pipes, ducts, conduits, wires and appurtenant equipment
serving the Subleased Premises; and (d) the right to use, on a first-come,
first-serve basis, an undesignated, pro-rata portion of the parking spaces
available to the tenants or occupants of the Office Premises pursuant to the
Office Lease in accordance with and subject to all applicable terms and
conditions set forth in the Office Lease. Said pro-rata portion of parking
spaces shall be determined based on the ratio of the rentable square footage of
the Subleased Premises to the total rentable square footage of the Office
Premises, as such ratio may change from time to time. Sublessee shall have no
rights to or interests in any other portion of the Office Premises, except as
otherwise provided herein. Sublessee acknowledges that it has reviewed, and
hereby accepts and agrees to be bound by, the terms and conditions of Office
Lease as it applies to the Subleased Premises, except for these terms and
conditions excluded herein.



                                       3
<PAGE>

         2.4. Sublease Subject to Office Lease. Sublessee acknowledges that this
Sublease is subject and subordinate in all respects to the Office Lease.
Therefore:

         A.       Each of Sublessor and Sublessee agrees that it will not take
                  any action which would constitute a default under the Office
                  Lease, as applicable to this Sublease, and further agrees to
                  indemnify, defend, and hold the other party harmless from and
                  against any and all liability, loss, cost, damage or expense,
                  including reasonable attorneys fees, arising out of or in
                  connection with any act or failure on the part of such party
                  which constitutes a default under this Sublease or under the
                  Office Lease.

         B.       Wherever Sublessor's consent is required under this Sublease,
                  the consent of the Landlord shall also be required (to the
                  extent set forth in the Office Lease). It is understood and
                  agreed that Sublessor shall not be deemed to be unreasonable
                  in withholding its consent if the Landlord has not granted its
                  consent.

         C.       Except as may be expressly stated to the contrary elsewhere
                  herein, Sublessee acknowledges and agrees that Sublessor shall
                  have no obligation to provide any services to the Subleased
                  Premises, to perform any maintenance of or repairs to the
                  Subleased Premises, or to perform any other obligation
                  required to be performed by the Landlord under the Office
                  Lease. Provided, however, Sublessor agrees that it will take
                  all commercially reasonable steps to enforce its (and
                  therefore Sublessee's) rights as Tenant under the Office Lease
                  with respect to all terms and provisions of the Office Lease,
                  all as if Sublessor had remained in occupancy of the Subleased
                  Premises.

         D.       Sublessee acknowledges and agrees that Sublessor shall have no
                  liability or obligation to Sublessee based upon any
                  representation or warranty made by the Landlord to Sublessor
                  under the Office Lease or based upon any act or omission of
                  the Landlord or the agents, employees or contractors of the
                  Landlord.

         2.5. Sublessor's Representations and Warranties. Sublessor represents
and warrants to Sublessee as follows:

         A.       The Office Lease is in full force and effect; Sublessor is the
                  Tenant under the Office Lease; no default by Sublessor under
                  the Office Lease now exists; Sublessor has full right and
                  power to execute this Sublease and to lease the Subleased
                  Premises to Sublessee, subject only to the consent of the
                  Landlord under the Office Lease (to the extent required
                  therein); no agreement or understanding exists between the
                  Sublessor and the Landlord except as disclosed in this
                  Sublease; and the Office Lease has not been amended, modified,
                  supplemented or superseded in any manner except as disclosed
                  in this Sublease;

         B.       To the best of Sublessor's knowledge, there is no existing
                  default under the Office Lease on the part of the Landlord;
                  and

         C.       Sublessor agrees that, so long as Sublessee shall pay the rent
                  due under this Sublease and shall perform all other
                  obligations of Sublessee herein contained: (a) Sublessee shall
                  be entitled to the peaceful and quiet enjoyment of the
                  Subleased Premises from and against the claims of all persons
                  claiming under Sublessor, and Sublessor shall comply with its
                  obligations under this Sublease; and (b) Sublessor will not
                  amend, modify or supplement any of the terms and conditions of
                  the Office Lease in a manner that would adversely affect
                  Sublessee's use and occupancy of the Subleased Premises or
                  rights under this Sublease, without, in each instance,
                  obtaining Sublessee's prior written consent.



                                       4
<PAGE>

         2.6. Access. Sublessee shall have access to the Subleased Premises
twenty-four (24) hours per day, seven (7) days per week, subject to Sublessee's
compliance with Landlord's access and security policies and procedures in place
for the Office Premises, if any.

         Sublessor may enter the Subleased Premises at reasonable times to
examine the Subleased Premises or to make any repairs or replacements Sublessor
may deem necessary to avert an emergency. Sublessor's entry to the Subleased
Premises shall be upon reasonable prior notice to Sublessee (except in cases of
emergency) and any work done in the Subleased Premises shall be performed in a
manner which minimizes interference with Sublessee's use and occupancy of the
Subleased Premises.

         2.7. Use. Sublessee shall use the Subleased Premises for the uses
permitted by the terms and conditions of the Office Lease.

ARTICLE III:  SUBLEASE TERM

         3.1. Sublease Term. The term of this Sublease (the "Sublease Term")
shall commence as of the Effective Date and continue thereafter through and
including the Expiration Date, unless extended or sooner terminated by the terms
of this Sublease.

         3.2. Sublessee's Termination Option. Subject to the consent or approval
of Landlord (if and to the extent required under the terms of the Office Lease),
Sublessee may elect to terminate this Sublease at any time as to all or any
portion of the Subleased Premises by giving Sublessor written notice of such
election at least sixty (60) days before the effective date of such termination,
which termination date shall be specified in such notice. Such notice shall also
specify that portion of the Subleased Premises as to which Sublessee is
terminating this Sublease. Sublessee shall continue to be liable for all Base
Rent and Additional Rent payable under this Sublease up to the effective date of
termination. If Sublessee has exercised its right to terminate this Sublease
only with respect to a portion of the Subleased Premises, the Base Rent shall be
adjusted as of the termination date as provided in Section 4.1 below. This
Sublease shall terminate on the termination date specified in such notice with
respect to that portion of the Subleased Premises specified in such notice with
the same force and effect as if such date were the last day of the Sublease
Term. The term "Subleased Premises", as used hereunder, shall refer to the
Subleased Premises less any portion of the Subleased Premises as to which
Sublessee has effectively exercised a right of termination. In the event
Sublessee elects to terminate this Sublease with respect to a portion of the
Subleased Premises only, it is understood and agreed that the portion of the
Subleased Premises so terminated shall be separately demisable by Sublessor. In
the event that Sublessee exercises its termination option with respect to a
portion only of the Subleased Premises, Sublessor and Sublessee hereby agree
that they will cooperate in connection with any reconfiguration of the common
areas and elements of the Subleased Premises that such partial termination may
necessitate (subject to Section 5.1 hereof).



                                       5
<PAGE>

         3.3. Holdover. Sublessee covenants and agrees to vacate and surrender
the Subleased Premises (or any applicable portion thereof) to Sublessor, in
broom clean condition, free of personal property, furniture and fixtures, on or
before the expiration or the earlier termination of the term of this Sublease,
as the case may be. Any holdover by Sublessee following the expiration of the
term (or following the termination of this Sublease with respect to a portion of
the Subleased Premises as herein provided) shall, at Sublessor's option, be
treated as a tenancy at sufferance at a daily rate equal to one and one-half
times the Base Rent payable by Sublessee immediately preceding such holdover and
shall otherwise be on the terms and conditions of this Sublease so far as the
same may be applicable. Sublessee hereby agrees to indemnify and hold Sublessor
harmless from and against any loss, cost or expense incurred by Sublessor as the
result of any holdover by Sublessee.

ARTICLE IV:  PAYMENT OF RENT

         4.1. Rent. Commencing as of the Effective Date and continuing
thereafter through and including the Expiration Date (or the date this Sublease
is earlier terminated), Sublessee shall pay Sublessor, in advance on or before
the first (1st) day of each calendar month, without deduction, setoff or defense
except as otherwise provided herein or in the Office Lease, the Base Rent
payable for that month.

         If Sublessee exercises its termination right with respect to a portion
of the Subleased Premises, the Base Rent as set forth above will be recalculated
as of the effective termination date based on (i) the rentable square footage of
the portion of the Subleased Premises as to which Sublessee is not terminating
this Sublease, and (ii) the total rentable square footage of the Subleased
Premises immediately prior to such termination.

         4.2. Sublessee's Payment Increases Pro-Rata Share of Base Year
Expenses. Commencing as of (i) January 1, 2001, with respect to Operating
Expenses and Additional Expenses, and (ii) July 1, 2000, with respect to Taxes,
and continuing thereafter throughout the Sublease Term, Sublessee shall pay to
Sublessor Sublessee's Pro-Rata Share (as such term is hereinafter defined) of
all increases in the total amount of (a) Operating Expenses payable by Sublessor
to Landlord over the comparable charges payable by Sublessor for calendar year
2000, (b) Taxes payable by Sublessor to Landlord over the comparable charges
payable by Sublessor for fiscal year 2000 (i.e. July 1, 1999 to June 30, 2000),
and (c) Additional Expenses over the comparable costs payable by Sublessor with
respect to calendar year 2000. All payments made by Sublessee of Operating
Expenses, Taxes or Additional Expenses hereunder shall hereinafter sometimes be
referred to collectively as "Additional Rent".

         Sublessee's Pro-Rata Share as set forth above shall equal the ratio of
the rentable square footage of the portion of the Subleased Premises that
Sublessee is occupying as of the Effective Date to the total rentable square
footage of the Office Premises. If Sublessee exercises its termination right
with respect to a portion of the Subleased Premises, Sublessee's Pro-Rata Share
shall be recalculated as of the effective termination date based upon (i) the
rentable square footage of the portion of the Subleased Premises as to which
Sublessee is not terminating this Sublease, and (ii) the total rentable square
footage of the Subleased Premises immediately prior to such termination.



                                       6
<PAGE>

         Such amounts shall be paid by Sublessee to Sublessor within fifteen
(15) days after notice from Sublessor that such amounts are due; provided,
however, Sublessee shall make monthly payments of such charges (as reasonably
estimated by Sublessor) if such monthly payments are required to be made by
Sublessor pursuant to the Office Lease.

         Sublessee shall be entitled to Sublessee's Pro-Rata Share of any and
all refunds of overpayments of Operating Expenses, Additional Expenses and Taxes
paid or credited to Sublessor by Landlord to the extent that such refunded or
credited amounts relate to amounts paid by Sublessee to Sublessor hereunder.
Sublessor shall account to Sublessee at least annually as to Sublessor's actual
payments to Landlord for and with respect to Operating Expenses, Additional
Expenses and Taxes, and shall promptly reimburse or credit Sublessee for any
overpayment made by Sublessee of such amounts. Sublessor shall promptly pay such
amounts to Sublessee or credit such amounts against the next monthly installment
of Base Rent due from Sublessee to Sublessor under this Sublease. Sublessor
shall promptly supply to Sublessee copies of all notices, supporting
documentation and other materials received from Landlord which pertain to
Operating Expenses, Additional Expenses or Taxes, or to increases in such
charges.

         4.3. Other Amounts. Sublessee shall be responsible for and shall
promptly and timely pay all separately metered and directly billed utility costs
and expenses pertaining to extraordinary utility requirements of Sublessee for
portions of the Subleased Premises (e.g., a data room). To the extent any such
extraordinary utility costs and expenses cannot be separately metered, Sublessee
shall pay its reasonable allocable share of such charges based upon the rentable
square footage of that portion of the Subleased Premises subject to such
extraordinary usage (taking into account any extraordinary usage by Sublessor).

         Sublessee shall be responsible for and shall promptly and timely pay
all taxes and other assessments levied or assessed directly against it or its
personal property located at the Subleased Premises directly to the taxing
authority.

ARTICLE V:  IMPROVEMENTS; REPAIR AND MAINTENANCE

         5.1. Improvements to Office Premises. Sublessee hereby acknowledges and
warrants to Sublessor that it has had the opportunity to inspect and familiarize
itself with the Subleased Premises and has done so. Sublessee hereby accepts the
Subleased Premises in its current "AS IS, WHERE IS" condition, without any
obligation on the part of Sublessor to prepare or construct the Subleased
Premises for Sublessee's occupancy, except as otherwise provided herein.



                                       7
<PAGE>

         In the event that Sublessee exercises its termination option with
respect to a portion of the Subleased Premises, any demising walls, alterations
and improvements necessary to reconfigure the premises for occupancy by
Sublessor or by another occupant or tenant shall be constructed by Sublessor.
Sublessee shall cooperate with Sublessor as necessary in connection with the
construction of any such demising walls, alterations or improvements. Within
thirty (30) days of receipt by Sublessee of a bill therefor (accompanied by
reasonably detailed supporting documentation), Sublessee shall pay to Sublessor
the actual, out-of-pocket costs incurred by Sublessor in constructing demising
walls between that portion of the Subleased Premises surrendered by Sublessee
and the remainder of the Subleased Premises. Sublessee shall not be liable for
any incremental costs incurred by Sublessor in constructing any other
improvements, additions or alterations to such surrendered space. Sublessor
shall obtain the Landlord's consent or approval, to the extent that such consent
or approval is required under the Office Lease, to the construction of any such
demising walls, alterations or improvements.

         Any work performed by either Sublessor or Sublessee pursuant to this
Sublease shall be done in a good and workmanlike manner and in compliance with
all applicable laws and all lawful ordinances, regulations and orders of
governmental authority and insurers of the Office Premises and the Building and
in accordance with all applicable requirements of the Office Lease.

         Sublessee agrees to pay promptly when due the entire cost of any work
done at or on the Subleased Premises by Sublessee or its agents, employees or
contractors, and not to cause or permit any liens for labor or materials
performed or furnished in connection therewith to attach to the Office Premises
or the Building, and immediately to discharge any such liens which may so
attach.

         5.2. Repair and Maintenance of the Subleased Premises. Sublessee shall
be responsible for the maintenance and repair of the interior, non-structural
elements of the Subleased Premises, including, without limitation, interior
doors, interior security and any subsystems installed by Sublessee for its use.
Sublessee shall submeter all data rooms.

         It is understood that the Landlord has certain obligations to make
repairs to the Office Premises as set forth in the Office Lease. Sublessor shall
have no obligation or liability to Sublessee in the event that the Landlord does
not make such repairs except that Sublessor shall request that the Landlord make
any such repairs and shall use commercially reasonable efforts to enforce any
applicable provisions of the Office Lease with respect to such repairs.
Sublessee agrees that it will keep the Subleased Premises neat and clean and
maintain the Subleased Premises in good order, condition and repair excepting
only for ordinary wear and tear, those repairs for which the Landlord is
responsible under the terms of the Office Lease and damage by fire and other
casualty and as a consequence of the exercise of the power of eminent domain, or
where the need for the repairs is caused by any act or neglect of Sublessor or
any contractor of Sublessor; and Sublessee shall surrender the Subleased
Premises (or any applicable portion thereof) and all alterations, improvements,
and additions thereto at the end of the Sublease Term in such condition.
Sublessee shall not permit or commit any waste, and Sublessee shall be
responsible for the cost of repairs which may be necessary by reason of damages
to common areas in the Office Premises and the Building caused by Sublessee or
Sublessee's agents, employees and contractors.

<PAGE>

{THIS PARAGRAPH WILL BE REVISED TO ACCOUNT FOR PARTICULAR LEASES WHICH IMPOSE
SPECIFIC REPAIR AND MAINTENANCE OBLIGATIONS ON TENANT}

         5.3. Signage. Subject to the written consent of Sublessor, which
consent shall not be unreasonably withheld, conditioned or delayed (and the
consent or approval of Landlord, if and to the extent required under the Office
Lease), Sublessee shall have the right to affix signs to the interior or
exterior of the Subleased Premises, provided that such signs comply with all
applicable requirements of the Office Lease.

ARTICLE VI:  DEFAULT

         6.1. Default. It is agreed that the relationship between, and the
rights of, Sublessor and Sublessee shall, with respect to enforcement of the
provisions of this Sublease and default hereunder and the termination hereof, be
governed by the applicable default and remedies provisions of the Office Lease
as if Sublessor and Sublessee were Landlord and Tenant, thereunder,
respectively, except as modified by the immediately succeeding sentence. The
parties acknowledge that an action required and not taken by Sublessee under
this Sublease may place Sublessor in default of its obligations under the Office
Lease. Therefore, the parties hereby agree that, as between Sublessor and
Sublessee, the period afforded Sublessor under the Office Lease to cure a
monetary default shall be reduced by three (3) days, and the cure period for
non-monetary defaults shall be reduced by five (5) days.

         Furthermore, to the extent that the Office Lease requires notice to be
given by Landlord to Tenant, Sublessee agrees that Sublessor shall transmit such
notice to Sublessee as soon as such notice is received by Sublessor. Further,
whenever Tenant has an obligation to perform any act or to give any notice to
Landlord under the Office Lease and such obligation is assumed by Sublessee
under this Sublease, then Sublessee shall perform such act or give such notice
at least three (3) days before the due date.

         6.2. Indemnity. Each of Sublessor and Sublessee agrees to indemnify,
defend and hold harmless the other party from and against any and all
liabilities, damages, losses, costs, assessments, penalties, fines, expenses and
fees, including reasonable attorney's fees, resulting from such party's breach
of any of its obligations under the Office Lease or under this Sublease.

         6.3. Attorneys' Fees. In the event of any litigation between the
parties hereto with respect to the subject matter hereof, the unsuccessful party
or parties agree(s) to pay to the successful party or parties all reasonable
costs, expenses, expert witness fees and costs and reasonable attorneys' fees
incurred therein by the successful party or parties, which shall be included as
a part of any judgment or order rendered therein.

ARTICLE VII:  ASSIGNMENT AND SUBLETTING

         7.1. Assignment and Subletting. Except as otherwise provided herein,
Sublessee may not assign this Sublease or sublease the Subleased Premises or any
part thereof without the prior written consent of Sublessor, which consent may
be granted or withheld in Sublessor's sole discretion (subject, in any event, to
any approval or consent of Landlord required under the Office Lease). No
permitted assignment or sublease shall release Sublessee of any liability under
this Sublease and the consent of Sublessor to any one assignment or subletting
shall not be deemed to be Sublessor's consent to any other or further assignment
or subletting.

         Subject to any required consent or approval of the Landlord under the
Office Lease, the Sublessor agrees that the Sublessee shall have the right
(without the requirement of obtaining the Sublessor's consent or approval) to
assign its interest under this Sublease, sublease all or any portion of the
Subleased Premises, or permit the use of any portion of the Subleased Premises,
by any entity controlling, controlled by, or under common control with, the
Sublessee. Furthermore, Sublessee may, without the Sublessor's consent or
approval, transfer its interest in this Sublease to the surviving entity in the
event of merger, consolidation by or with Sublessee, or to the purchaser of all
or substantially all of the assets or stock of Sublessee (or its parent). In no
event shall the initial offering of stock to the public by Sublessee or its
parent (or the subsequent sale of such stock) be deemed an assignment or
transfer by Sublessee.

ARTICLE VIII: INSURANCE

         8.1. Insurance. Sublessee shall obtain and maintain all insurance
required to be carried by Sublessor pursuant to the Office Lease to the extent
such requirements are applicable to the Subleased Premises. All liability
insurance policies so required to be carried by Sublessee shall name Landlord
and Sublessor as additional insureds thereunder. Sublessee shall provide
Sublessor with insurance certificates evidencing the required insurance coverage
upon the execution hereof and from time to time thereafter as reasonably
requested by Sublessor. Sublessor shall obtain and maintain all insurance it is
required to obtain and maintain under the Office Lease, and shall name Sublessee
as an additional insured on all liability policies so required to be carried by
it. Sublessor shall provide Sublessee with certificates evidencing such required
insurance coverage from time to time as reasonably requested by Sublessee.
Sublessee and Sublessor shall each also maintain workers' compensation insurance
as required by law.

{THIS PROVISION SHALL BE MODIFIED TO THE EXTENT THE OFFICE LEASE OBLIGATES
TENANT TO CARRY CASUALTY INSURANCE FOR THE BUILDING}

         8.2. Waiver of Subrogation. Any insurance carried by either party with
respect to the Subleased Premises and property therein or occurrences thereon
shall include a clause or endorsement denying to the insurer rights of
subrogation against the other party to the extent rights have been waived by the
insured prior to occurrence of injury of loss. Each party, notwithstanding any
provisions of this Sublease to the contrary, hereby waives any rights of
recovery against the other for injury or loss to property due to hazards covered
by insurance or hazards required to be covered by insurance hereunder or under
the Office Lease.

ARTICLE IX:  MISCELLANEOUS

         9.1. Termination of Office Lease. Except where Sublessee attorns to
Landlord, any termination of the Office Lease shall terminate this Sublease.
Sublessee acknowledges and agrees that: (i) Sublessee will, at Landlord's
election, in the event the Office Lease is terminated for any reason, attorn
directly to Landlord on the terms set forth in this Sublease, and (ii) Sublessee
shall, upon receipt of written notice from Landlord stating that an Event of
Default (as defined in the Office Lease) has occurred and requiring Sublessee to
pay the rent to Landlord, pay to Landlord the rent due and payable under this
Sublease so long as Sublessee's occupancy is not disturbed. If Landlord so
directs Sublessee, Sublessor hereby consents to the payment by Sublessee of the
rent due under this Sublease directly to Landlord, and Sublessor agrees that all
amounts so paid by Sublessee to Landlord shall be credited to amounts due under
this Sublease. Sublessor shall notify Sublessee of a default under the Office
Lease by Landlord (where a notice of default is given by Sublessor to Landlord)
or by Sublessor (where Landlord gives notice of such default to Sublessor).

         9.2. Separation; Confidentiality. Each of the parties hereto
acknowledges that the employees and guests of the other party have the right to
use in common with the employees and guests of such party certain common areas
within the Office Premises and the Building, even though both parties expect to
maintain separate and private work places. Neither Sublessor nor Sublessee shall
have access to the other's private offices, secretarial work areas, file storage
areas or other areas where files or documents of each party are stored or
utilized, and each of Sublessor and Sublessee shall avoid viewing the files or
documents of the other party when using the common areas of the Subleased
Premises. Each party hereto agrees that in the event it obtains possession of or
becomes aware of any papers, documents, files or other information involving the
other party's business, employees, or clients, such party shall promptly return
any such papers, documents or files, shall keep all such information
confidential, and shall not disclose any of such information to any third
parties without the prior written consent of the other party.

         9.3. Notice. Except as otherwise provided in this Sublease, notices
required or desired to be given hereunder shall be effective either upon
personal delivery or three (3) business days after deposit in the United States
mail, by certified mail, return receipt requested or one (1) business day after
deposit with a nationally recognized overnight courier service such as Federal
Express, addressed to the parties at their respective addresses set forth in
Article I of this Sublease as Sublessor's Notice Address and Sublessee's Notice
Address. Either party may change its address for notice by giving written notice
in the manner hereinabove provided.

         9.4. Construction. This Sublease shall be construed in accordance with
the laws of the State in which the Building is located.



                                       11
<PAGE>

         9.5. General. This Sublease shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns,
subject at all times, to all agreements and restrictions contained in the Office
Lease (except such agreements and restrictions as are expressly excluded
herein).

         No failure or delay by either of Sublessor or Sublessee to exercise any
right or power given to it or to insist upon strict compliance by the other
party with any obligation imposed on it hereunder, and no custom or practice of
either party hereto at variance with the terms hereof shall constitute a waiver
or modification of the terms hereof by such party or any right it has herein to
demand strict compliance with the terms hereof by the other party.

         The agreements contained herein constitute the entire understanding
between the parties with respect to the subject hereof, and supersede all prior
agreements, written or oral, inconsistent herewith.

         If any provision of this Sublease or the application thereof to any
person or circumstance shall be invalid or unenforceable to any extent, the
remainder of the Sublease and the application of such provisions to other
persons or circumstances shall not be affected thereby and shall be enforced to
the fullest extent permitted by law.

         The captions and headings contained herein are merely labels to aid in
locating sections and are not a substantive part of this Sublease nor shall they
be interpreted as such.

         This Sublease may be amended only in writing, signed by all parties
hereto and consented to by Landlord (to the extent that such consent is required
under the Office Lease).

         This Sublease may be executed in one or more counterparts and each
executed counterpart shall be considered an original.

         attached hereto (the "Lease").

B.       Assignee is an affiliate of Assignor.

C.       Assignor has agreed to assign to Assignee all of Assignor's right,

         to assume all of the Assignor's duties and obligations under the Lease
         in accordance with the terms set forth herein.

                                   AGREEMENTS:

         NOW, THEREFORE, in consideration of the foregoing premises and the

         1. Assignment. Assignor does hereby assign, transfer, convey and

[Genuity Inc. Address]


Re:      Financial Support Agreement Regarding Guaranty of Obligation for the
         benefit of [___________________], dated__________


Ladies and Gentlemen:

In consideration of the agreement by GTE Corporation ("GTE") to issue or
continue to maintain the guaranty described above which is attached as Exhibit A
hereto (the "Guaranty") following the transfer of GTE's controlling interest in
Genuity Inc. ("Genuity") as contemplated by GTE and Bell Atlantic Corporation's
Supplemental Filing with the FCC on January 27, 2000 (the "Separation"), Genuity
agrees to pay GTE a fee pursuant to the following terms and conditions:

Guaranty Fee:                       Guaranty Fee shall be ____% per annum,
                                    calculated monthly, charged on the month-end
                                    outstanding balance of the Guaranty, as
                                    evidenced by the amortization schedule
                                    attached thereto or included therein, and
                                    will be payable semi-annually on June 30 and
                                    December 31 of each calendar year. If the
                                    Guaranty is outstanding for less than a full
                                    calendar month, Guaranty Fee shall be
                                    computed based on the outstanding balance of
                                    the Guaranty on each calendar day of such
                                    month that the Guaranty shall remain in
                                    effect.

Adjustment to Guaranty Fee:         The Guaranty Fee set forth above was
                                    determined based on the assumption that
                                    Genuity's credit rating post-Separation
                                    would be equivalent to the average of the
                                    ratings of BBB/Baa2 and BBB-/Baa3. GTE shall
                                    have a one-time right to increase, effective
                                    prospectively, the Guaranty Fee (the
                                    "Adjusted Guaranty Fee") if either one of
                                    the following events occurs: (i) Standard &
                                    Poor's issues a credit rating for Genuity of
                                    BB+ or less or (ii) Moody's issues a credit
                                    rating for Genuity of Ba1 or less. Such
                                    right may be exercised at any time by
                                    written notice to Genuity.

<PAGE>

                                    If either of the events described in (i) or
                                    (ii) above occurs, the Adjusted Guaranty Fee
                                    shall be determined by GTE by averaging the
                                    rates quoted to GTE by three nationally
                                    recognized banking institutions for a credit
                                    equivalent to the published credit ratings
                                    of Genuity. The Adjusted Guaranty Fee shall
                                    become the Guaranty Fee payable under this
                                    letter from and after the date on which GTE
                                    provides Genuity written notice of the
                                    Adjusted Guaranty Fee.


Payment of Fee:                     Guaranty Fee is due not later than 5
                                    business days following the end of each
                                    semi-annual payment period and shall be
                                    delivered by electronic funds transfer to
                                    [wire transfer instructions] or such other
                                    bank account as shall be provided to Genuity
                                    by GTE in writing at least 5 business days
                                    prior to the date of electronic funds
                                    transfer.

                                    In the event the Guaranty is terminated,
                                    replaced by Genuity or expires prior to the
                                    end of the semi-annual payment period,
                                    Guaranty Fee will be due not later than 5
                                    business days following the termination of
                                    all obligations of GTE under the Guaranty.

Late Payment Fee:                   A Late Payment Fee in the amount of prime
                                    rate plus 1.00% per annum, calculated daily,
                                    commencing on the day immediately following
                                    the due date and based upon the number of
                                    days elapsed prior to payment of all amounts
                                    due shall be included with any overdue
                                    payment of Guaranty Fee.

Duty of Inquiry:                    GTE shall have no obligation to consult with
                                    Genuity or make any independent
                                    investigation prior to any decision to honor
                                    or dishonor any payment request under the
                                    Guaranty.

Immediate Repayment:                If GTE makes any payment under the Guaranty,
                                    GTE agrees to notify Genuity in writing, at
                                    the address set forth at the end of this
                                    letter or such other address as shall be
                                    subsequently provided to GTE by Genuity in
                                    writing, within three business days of the
                                    amount of such payment, and Genuity agrees
                                    to pay such amount to GTE within one
                                    business day following the date of such
                                    written notice. A Late Payment Fee shall be
                                    applied to any amounts not received when
                                    due.

Re:      Request by Genuity Inc. ("Genuity") for
         Continuation of Financial Support after Separation


GTE Corporation ("GTE") acknowledges your request for the continuation of
financial support by GTE Corporation after the transfer of GTE's controlling
interest in Genuity as contemplated by GTE and Bell Atlantic Corporation's
Supplemental Filing with the FCC on January 27, 2000 (the "Separation"). Genuity
will not have published credit ratings from any nationally recognized credit
rating services for some period of time after the Separation. Genuity has
maintained that, in order to continue its regular business operations, Genuity
may need some continuing financial support from GTE, in the form of new
guaranties related to financial obligations entered into post-Separation, until
Genuity has established such credit ratings.

GTE is willing to offer financial support to Genuity post-Separation, in the
form of GTE Corporation guaranties, on the following terms and conditions:

Terms of Financial Support:         GTE shall issue guaranties in support of
                                    real estate lease obligations of Genuity
                                    (each, a "Guaranty") on the same basis and
                                    on the same terms and conditions as GTE
                                    issued such guaranties on behalf of Genuity
                                    and other GTE affiliated companies prior to
                                    Separation, EXCEPT as otherwise set forth in
                                    this letter. GTE shall not be obligated to
                                    issue any Guaranty upon terms or conditions
                                    less favorable than GTE's standard form of
                                    guaranty attached as Exhibit A.

Financial Support Agreement:        As a condition to the issuance of any
                                    Guaranty post-Separation, Genuity shall
                                    execute the form of Financial Support
                                    Agreement attached as Exhibit B to this
                                    letter for each Guaranty requested by
                                    Genuity and issued by GTE.

Term of Commitment:                 GTE shall continue to issue Guaranties until
                                    the earlier of (i) the date that is six
                                    months after the date of Separation or (ii)
                                    the date on which both Standard & Poor's and
                                    Moody's have published credit ratings for
                                    Genuity.

Guaranty Fee:                       The Guaranty Fee for each Guaranty so issued
                                    shall be 1.0% per annum; provided, however,
                                    that the Guaranty Fee may be increased to
                                    the Market Rate (hereinafter defined) if the
                                    Market Rate exceeds 1.0% per annum by 0.25%
                                    or more at the time each Guaranty is issued.

                                    The Market Rate shall be determined by GTE
                                    by averaging the rates quoted to GTE by
                                    three nationally recognized banking
                                    institutions for a credit equivalent to the
                                    credit of Genuity. For purposes of this
                                    agreement, the credit of Genuity is assumed
                                    to be equivalent to the average of the
                                    ratings of BBB/Baa2 and BBB-/Baa3.

Negotiation of Guaranties:          Genuity understands and acknowledges that
                                    GTE shall be solely responsible for the
                                    negotiation of the terms and conditions with
                                    the lessor or lessor's representative,
                                    including dollar and term limits, of each
                                    Guaranty requested.

Genuity, as used in this letter, means and includes Genuity Inc. and its
wholly-owned subsidiaries, as well as the entity described and defined as DataCo
in the Supplemental FCC Filing mentioned hereinabove.

         THIS FIRST AMENDMENT to the Master Services Agreement (the "Agreement")
is executed by and between GTE Network Services, consisting of the GTE telephone
operating companies listed in Attachment 1 ("GTE") and GTE Global Networks
Incorporated ("GNI"). (GTE and GNI being referred to collectively as the
"Parties".)

                                    RECITALS

WHEREAS, the purpose of this Amendment is to modify the Agreement between the
parties finally executed on September 14, 1999 by modifying the termination
provision thereof and by revising Exhibit B thereto, the Statement of Work (SOW)
to (a) modify the termination provision, (b) include a table of metrics, and (c)
adjust pricing.

WHEREAS, the Parties now wish to adopt the terms set forth below as an amendment
to the Agreement.

NOW, THEREFORE, in consideration of the mutual promises, provisions and
covenants herein contained, the sufficiency of which is hereby acknowledged, the
Parties agree as follows:

         1.       Section 4.2 of the Agreement is deleted and replaced with the
                  following:

                  Notwithstanding anything to the contrary contained in this
                  Agreement, GTE may terminate this Agreement at the expiration
                  of the then current term by providing notice to GNI at least
                  ninety (90) calendar days prior to the expiration of such
                  term. GNI may terminate this Agreement at any time by
                  providing at least ninety (90) calendar days prior written
                  notice of termination to GTE. Termination of the Agreement
                  pursuant to this Section 4.2 shall not be effective as to work
                  under any particular Statement of Work until the earlier of
                  the expiration or termination of such Statement of Work


         2.       A new Section 3.13 is added to the SOW as follows:

                  "The NOC will use commercially reasonable efforts to adhere to
                  the performance metrics set forth in the table of metrics
                  attached hereto as Attachment C and incorporated herein by
                  this reference. These metrics will be used as a method to
                  build historical data. The parties recognize that attainment
                  or non-attainment may be largely subjective. The parties will
                  review and agree to the validity of data used to determine
                  attainment. These metrics are not an unqualified (absolute)
                  measurement or the sole measurement of performance. Attainment
                  or non-attainment of such metrics shall not affect
                  compensation due under this SOW."

                  Attachment 2 hereto, NOC Metrics, is added to the SOW as
                  Attachment C thereto.

         3.       Section 6.0 of the SOW is deleted and replaced with the
                  following:

                  The labor charges represent the year to year recurring term
                  charges of this SOW unless otherwise negotiated and agreed to
                  by both parties.

                  Notwithstanding anything to the contrary contained in this
                  SOW, Section 6.0, Compensation, is at all times subject to
                  review and modification to conform with any applicable
                  regulatory requirement."


         4.       Section 8.1 of the SOW is deleted and replaced with the
                  following:

                  "Notwithstanding any other provision of this SOW or the
                  Agreement, this SOW is terminable by GNI on ninety (90)
                  calendar days written notice to GTE."

                  Agreement shall remain in full force and effect.

         6.       If any provision in the Agreement conflicts with this First
                  Amendment, this First Amendment shall control.

     percentage as the Plan Administrator may determine in its sole discretion)
     of his Eligible Salary, Bonus, and/or Award for the Plan Year (or the
     period thereof during which the election is in effect); provided that any
     such deferral must be made in integral multiples of 1% of the Eligible
     Salary, Bonus, or Award; and provided further that the Committee may in its

     (4)  Treatment of Deferral. If a Participant does not specify that the
          Annual Deferral should be treated as if held entirely in cash,
          entirely in Genuity Common Stock, partly in cash and partly in Genuity
          Common Stock (and if so the percentage allocation between cash and
          Genuity Common Stock in integral multiples of 1%), or in such other
          investment vehicles as the Committee may allow, the Annual Deferral
          shall be treated as if held entirely in cash.

     (5)  Payment Commencement. The election shall specify the year or events,
          selected by the Participant in accordance with Section 5.03, as of
          which payments with respect to the Annual Deferral are to commence
          under the Plan.

     (6)  Method of Payment. In the case of the election of a fixed commencement
          year pursuant to Sections 3.03(a)(5) and 5.03(a), the election shall
          specify the method, selected by the Participant in accordance with
          Section 5.02, in which payments with respect to the Annual Deferral
          are to be made under the Plan.

     (7)  Election Irrevocable. Except as otherwise specifically provided in the
          Plan, the amount of deferral, the treatment of the deferral, the
          payment commencement date, and the method of payment elected by a
          Participant with respect to an Annual Deferral in accordance with
          paragraphs (3) through (6), above, shall not be revocable or subject
          to modification at any time.

(b)  If the Plan Administrator determines, in its sole discretion, that a
     Participant has incurred unusual, extraordinary expenses or hardship caused
     by events beyond the Participant's control, such as accident or illness,
     the Plan Administrator may grant a Participant's request to reduce the
     amount of his Annual Deferral at any time, provided that the amount of the
     reduction must be limited to the amount reasonably necessary to relieve the
     hardship or financial emergency upon which the request is based.  A
     reduction in the deferral percentage effected pursuant to this subsection
     shall not otherwise alter the terms of the Participant's participation in
     the Plan.  The Plan Administrator may require a Participant who requests a
     reduction in an Annual Deferral under this subsection (b) to submit such
     evidence as the Plan Administrator, in its sole discretion, deems necessary
     or appropriate to substantiate the circumstances upon which the request is
     based.

(c)  A Participant may, within one year prior to normal retirement elect that
     all or part of such portion of his account that is treated as being held in
     Genuity Common Stock thereafter be treated as being held in cash or that
     all or part of such portion of his account that is treated as if held in
     cash thereafter be treated as if held in Genuity

     Common Stock; provided that only one such election may be made in any Plan
     Year.  The effective date of such a change in hypothetical investment shall
     be the date of the election.

(d)  A Participant may submit a request at any time to the Plan Administrator to
     modify the payment commencement date, the method of payment, or both, with
     respect to the Annual Deferral; provided that only one such request may be
     made in any Plan Year; and provided further that the request must be
     submitted before any payment is made to the Participant with respect to the
     Annual Deferral pursuant to ARTICLE V (other than an interim payment
     pursuant to Section 5.04).   If the modification has the effect of
     accelerating all or part of any payment otherwise due the Participant under
     ARTICLE V, the request shall be subject to the approval of the Plan
     Administrator, which approval the Plan Administrator may grant or deny in
     its sole discretion.  If the modification has the effect of deferring until
     a later calendar year all or part of any payment otherwise due the
     Participant under ARTICLE V, the request shall be granted, provided that
     the request is submitted at least 60 days before the last day of the
     calendar year immediately preceding the calendar year in which the payment
     otherwise would have been made to the Participant under ARTICLE V.  In no
     event shall the modification have the effect of accelerating the first day
     of the payment commencement year to less than one year from the date the
     modification is submitted to the Plan Administrator.

(e)  If a Participant becomes subject to a prohibition against continuing to
     have all or part of an Annual Deferral being treated as held in Genuity
     Common Stock because of an actual or potential conflict of interest, he
     shall be permitted a one-time election on the occurrence of the prohibition
     to have that portion of such Annual Deferral that is treated as if held in
     Genuity Common Stock thereafter treated as if held in cash; provided that
     the Plan Administrator may approve or disapprove such an election in its
     sole discretion.  The effective date of such an election shall be the first
     day of the month next following the month in which the election is received
     (or, if later, approved) by the Plan Administrator.  Within a reasonable
     amount of time from the removal of the prohibition referred to in the first
     sentence of this subsection (e), the Participant shall be afforded an
     election to treat as if held in Genuity Common Stock that portion of his
     account that was treated as if held in cash pursuant to the first sentence
     of this subsection (e); provided that the Plan Administrator may approve or
     disapprove such an election in its sole discretion.  The effective date of
     the election referred to in the preceding sentence shall be the first day
     of the calendar quarter next following the calendar quarter in which such
     election is received (or, if later, approved) by the Plan Administrator.
     The dollar value of the hypothetical shares of Genuity Common Stock with
     respect to which the elections described in this subsection (e) are made
     shall be calculated in accordance with Section 4.02(b).

3.04.  Designation of Beneficiaries.

     A Participant who makes a deferral election pursuant to Section 3.03 may
designate one or more beneficiaries under the Plan.  Notwithstanding Section
3.03(a)(7), a Participant may, at any time, revoke a prior designation and make
a new designation pursuant to this Section 3.04.  Any such designation or
revocation shall be in writing and shall be submitted to the Plan Administrator
prior to the Participant's death in such form and in such manner as is
acceptable to the Plan Administrator.

                     ARTICLE IV.    ACCOUNTS AND INTEREST

4.01.    Accounts.

(a)  Establishment of Accounts.  A separate bookkeeping account shall be
     maintained for each Participant.  Such account shall be (1) credited with
     the amounts deferred by the Participant pursuant to Section 3.03, (2)
     credited (or charged, as the case may be) with the hypothetical investment
     results determined pursuant to Section 4.02, and (3) charged with the
     amounts paid by the Plan to or on behalf of the Participant pursuant to
     ARTICLE V.

(b)  Subaccounts.  Within each Participant's account, separate subaccounts shall
     be maintained to the extent necessary for the administration of the Plan.
     For example, it may be necessary to maintain separate subaccounts where the
     Participant has specified different payment commencement dates or different
     methods of payment with respect to his Annual Deferrals for different Plan
     Years.

4.02.    Hypothetical Investment Performance.

(a)  Deemed Investment in Cash.  If an Annual Deferral is treated as if held in
     cash, the balance in a Participant's account that is so treated shall be
     determined in accordance with the following rules:

     (1)  Cash Credits. Any amount that would have been paid to a Participant
          during a calendar quarter but for his deferral election pursuant to
          Section 3.03 shall be credited to his account.

     (2)  Interest. Interest shall be credited to the account as follows: any
          cash credits during the calendar quarter shall earn interest from the
          day they are credited to the Participant's account, and any payments
          made from the account shall cease to earn interest on the day they are
          subtracted from the account. Cash balances under the account as of the
          end of the immediately preceding calendar quarter that were not
          withdrawn during the calendar quarter shall earn interest for the
          entire calendar quarter. The rate at which interest shall be credited
          for purposes of this section shall be the equivalent of an annualized
          rate equal to the Moody's Rate as of the day immediately preceding the
          beginning of the applicable calendar quarter.

(b)  Deemed Investment in Genuity Common Stock.  If an Annual Deferral is
     treated as if held in Genuity Common Stock, the balance in a Participant's
     account that is so treated shall be determined in accordance with the
     following rules:

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

   Genuity Inc. Executive Deferral Plan                                   Page 9
<PAGE>

     (1)  Conversion into Genuity Common Stock. Any amount that would have been
          paid to a Participant during a calendar quarter but for his deferral
          election pursuant to Section 3.03 and any matching contributions
          pursuant to Section 4.03 shall be converted into an equivalent number
          of hypothetical shares of Genuity Common Stock (including hypothetical
          fractional shares) by dividing the amount deferred for that calendar
          quarter by the average closing price of Genuity Common Stock on Nasdaq
          (or any other reporting system or market selected by the Committee)
          for the last 20 trading days of the immediately preceding calendar
          quarter.

     (2)  Deemed Reinvestment of Dividends. The number of hypothetical shares of
          Genuity Common Stock credited to a Participant's account pursuant to
          paragraph (1), above, shall be increased on each date that a dividend
          is paid on Genuity Common Stock. The number of additional hypothetical
          shares of Genuity Common Stock credited to a Participant's account as
          a result of such increase shall be determined, first, by multiplying
          the total number of hypothetical shares of Genuity Common Stock
          credited to the Participant's account on the dividend record date by
          the amount of the dividend declared per share of Genuity Common Stock
          on the dividend declaration date, and, then, by dividing the product
          so determined by the closing price of Genuity Common Stock on Nasdaq
          (or any other reporting system or market selected by the Committee) on
          the dividend declaration date (or if there was no reported sale of
          Genuity Common Stock on such date, on the next preceding day on which
          there was such a reported sale).

     (3)  Conversion Out of Genuity Common Stock. The dollar value of the
          hypothetical shares of Genuity Common Stock paid to or withdrawn from
          a Participant's account on any date shall be determined by multiplying
          the number of hypothetical shares of Genuity Common Stock paid to or
          withdrawn from the Participant's account on that date by the closing
          price of Genuity Common Stock on Nasdaq (or any other reporting system
          or market selected by the Committee) on that date.

     (4)  Effect of Recapitalization. In the event of a transaction or event
          described in this paragraph (4), the number of hypothetical shares of
          Genuity Common Stock credited to a Participant's account shall be
          adjusted in such manner as the Plan Administrator, in its sole
          discretion, deems equitable. A transaction or event is described in
          this paragraph (4) if and only if (A) it is a dividend or other
          distribution (whether in the form of cash, shares, other securities,
          or other property), extraordinary cash dividend, recapitalization,
          stock split, reverse stock split, reorganization, merger,
          consolidation, split-up, spin-off, combination, repurchase, or
          exchange of shares or other securities, the issuance of warrants or
          other rights to purchase

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

  Genuity Inc. Executive Deferral Plan                                   Page 10
<PAGE>

          shares or other securities, or other similar corporate transaction or
          event, and (B) the Plan Administrator determines that such transaction
          or event affects the shares of Genuity Common Stock, such that an
          adjustment pursuant to this paragraph (4) is appropriate to prevent
          dilution or enlargement of the benefits or potential benefits intended
          to be made available under the Plan.

(c)  Deemed Investment in Other Investment Vehicles.  An Annual Deferral may be
     treated as if held in such other investment vehicles as the Committee in
     its discretion may permit.  If an Annual Deferral is treated as if held in
     such other investment vehicle, the balance in a Participant's account that
     is so treated shall be determined in accordance with such rules as the
     Committee in its discretion may provide.

4.03.    Matching Contributions.

(a)  The Company shall credit to each Participant's account a number of
     hypothetical shares of Genuity Common Stock equal in value to the Matching
     Percentage of the percentage of the Participant's Eligible Salary that the
     Participant defers for each Plan Year; provided that the percentage of the
     Participant's Eligible Salary that shall be taken into account for this
     purpose shall not exceed the percentage of the Participant's compensation
     that is eligible for a matching contribution under the Genuity Inc. Savings
     Plan; and provided further that such hypothetical shares shall be credited
     only if the Participant is a participant in the Genuity Inc. Savings Plan
     and is eligible for a basic Matching Contribution under the Genuity Inc.
     Savings Plan for that Plan Year and has made Pre-Tax Contributions under
     the Genuity Inc. Savings Plan for that Plan Year that (i) in the aggregate
     equal 6% of the Base Amount and (ii) satisfy any other requirements
     established in the Genuity Inc. Savings Plan.

(b)  The Plan Administrator may credit to a Participant's account, for equitable
     reasons and good cause shown, an additional number of hypothetical shares
     (including fractional shares) of Genuity Common Stock equal in value to any
     Matching Contribution not credited to the Participant's account under the
     Genuity Inc. Savings Plan because of limits placed on such Matching
     Contributions under the terms of the Code or the Genuity Inc. Savings Plan;
     provided that, to the extent that the amount of such credit depends on the
     extent to which the Participant makes or does not make elective deferrals
     under the qualified cash or deferred arrangement under the Genuity Inc.
     Savings Plan, the credit shall not be made unless, for the pertinent Plan
     Year, the Participant has made the maximum elective deferral permissible
     under section 402(g) of the Code or the maximum elective deferral permitted
     under the terms of the Genuity Inc. Savings Plan.

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

  Genuity Inc. Executive Deferral Plan                                   Page 11
<PAGE>

(c)  If the Participant is not eligible to participate in the Genuity Inc.
     Savings Plan, the Company shall credit to the Partcipant's account a number
     of hypothetical shares of Genuity Common Stock equal in value to the
     Matching Percentage of the percentage of the Participant's Eligible Salary
     that the Participant defers for each Plan Year; provided that the
     percentage of the Participant's Eligible Salary that shall be taken into
     account for this purpose shall not exceed the percentage of the
     Participant's compensation that is eligible for a matching contribution
     under the Genuity Inc. Savings Plan; and provided further that such
     hypothetical shares shall be credited only if the Plan Administrator
     determines that the Participant would have been eligible for a basic
     Matching Contribution under the Genuity Inc. Savings Plan for that Plan
     Year had the Participant been eligible to participate in the Genuity Inc.
     Savings Plan for that Plan Year and that the Participant has satisfied any
     other requirements that the Plan Administrator imposes in its discretion.

(d)  For purposes of subsections (a), (b), and (c) above, the value of a
     hypothetical share of Genuity Common Stock shall be calculated  in the same
     manner as basic Matching Contributions under the Genuity Inc. Savings Plan
     are calculated.  Hypothetical shares credited to a Participant's account
     pursuant to this Section 4.03 shall be credited as of the same date as of
     which basic Matching Contributionss are made under the Genuity Inc. Savings
     Plan and shall be treated in accordance with Section 4.02(b).

4.04.    Hypothetical Nature of Accounts and Investments.

     Each account and investment established under this ARTICLE IV shall be
hypothetical in nature and shall be maintained for bookkeeping purposes only.
Neither the Plan nor any of the accounts established hereunder shall hold any
actual funds or assets.  The right of any person to receive one or more payments
under the Plan shall be an unsecured claim against the general assets of the
Company.  Any liability of the Company to any Participant, former Participant,
or beneficiary with respect to a right to payment shall be based solely upon
contractual obligations created by the Plan.  Neither the Company, the Board,
nor any other Person shall be deemed to be a trustee of any amounts to be paid
under the Plan.  Nothing contained in the Plan, and no action taken pursuant to
its provisions, shall create or be construed to create a trust of any kind, or a
fiduciary relationship, between the Company and a Participant or any other
Person.

                            ARTICLE V.    PAYMENTS

5.01.    Exclusive Entitlement to Payment.

     A Participant's deferral election pursuant to Section 3.03 shall constitute
a waiver of his right to receive the amount deferred and an agreement to receive
in lieu thereof the amounts payable to him at the times and in the amounts
specified in this ARTICLE V.  No other amounts shall be due under the Plan or
otherwise as a result of a Participant's deferral election pursuant to Section
3.03.

5.02.    Method of Payment.

     The payments to a Participant with respect to an Annual Deferral shall be
made solely in cash pursuant to the method provided for in either paragraph (a)
or (b), below, that is selected by the Participant in accordance with Section
3.03(a)(6), unless paragraph (c), below, is applicable.  A Participant may
select different methods of payment with respect to his Annual Deferrals for
different Plan Years.

(a)  Lump Sum.  A Participant may elect to receive payment with respect to an
     Annual Deferral in a lump sum.  The lump sum shall be payable to the
     Participant in cash as of the first business day of the payment
     commencement year.  The lump sum shall equal the portion of the balance in
     the Participant's account attributable to the Annual Deferral, determined
     as of the date of payment.

(b)  Installments.  A Participant may elect to receive the payments with respect
     to an Annual Deferral either in annual, semi-annual, quarterly or monthly
     installments for a period of not less than two or more than 20 years;
     provided that the number of years elected shall not extend the period of
     payment beyond the life expectancy of the Participant as determined under
     Table V of Treas. Reg. (S) 1.72-9 (as amended from time to time),
     determined on the basis of his age on the date as of which payments would
     commence.  If the number of years elected by a Participant would otherwise
     exceed the limits imposed by the preceding provisions of this Section
     5.02(b), he shall be deemed to have elected the maximum number of years
     permitted under such preceding provision.  Installments shall be payable to
     the Participant:

     (1)  if the Participant elects payment commencement in accordance with
          Section 5.03(a), beginning as of the first business day of the year
          selected as the payment commencement year; or

     (2)  if the Participant elects payment commencement in accordance with
          Section 5.03(b), beginning as of the date specified in that Section.

     Each installment shall equal the portion of the balance in the
     Participant's account attributable to the Annual Deferral, determined as of
     the date the

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

  Genuity Inc. Executive Deferral Plan                                   Page 13
<PAGE>

     installment is payable, multiplied by a fraction the numerator of which is
     one, and the denominator of which is the excess of the total number of
     installments elected by the Participant over the number of installment
     payments previously made under the schedule. For example, the respective
     fractions under a five-year schedule of annual installments are 1/5 for the
     first installment, 1/4 for the second installment, 1/3 for the third
     installment, 1/2 for the fourth installment, and 1/1 for the fifth and
     final installment.

(c)  Automatic Cash-Out.  A Participant who separates from service with the
     Company and whose entire account balance is equal to or less than $10,000
     shall receive payment in the form of a lump sum.  The lump sum shall be
     payable to the Participant in cash as soon as is reasonably practicable
     after the Participant's separation from service.

5.03.    Payment Commencement.

     Unless otherwise specifically provided in the Plan (including but not
limited to Section 5.05), the payments to a Participant with respect to an
Annual Deferral shall commence in accordance with paragraph (a), (b), or (c),
below, as selected by the Participant in accordance with Section 3.03(a)(5).

(a)  Fixed Commencement Year.  A Participant may select a specific year for the
     commencement of payments; provided that, if any of the events described in
     paragraph (b), below, occur before the payment commencement date selected
     pursuant to this paragraph (a), payment shall commence in accordance with
     paragraph (b).  A Participant may select different payment commencement
     years with respect to his Annual Deferrals for different Plan Years.

(b)  Termination, Disability, or Death.  A Participant may select as the payment
     commencement date the date of his Termination, Disability, or death.

     (1)  Termination. A Participant who incurs a Termination shall be paid any
          amounts deferred in annual installments over a period of 10 years or
          the payment schedule requested, in accordance with Section 5.02, at
          the time of Termination, whichever is shorter; provided that the Plan
          Administrator, in its sole discretion, may approve or deny any payment
          schedule requested at the time of Termination; provided further that
          no payment shall be made until the first business day more than 30
          days after the date of Termination; and provided further that, if at
          the time of Termination payments have commenced pursuant to paragraph
          (a), above, such payments shall continue according to the schedule on
          which they were then being paid.

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

  Genuity Inc. Executive Deferral Plan                                   Page 14
<PAGE>

     (2)  Disability. A Participant who incurs a Disability shall be paid any
          amounts deferred in annual installments over a period of 10 years;
          provided that a Participant at the time of onset of Disability may
          request a fewer number of installments; provided further that the Plan
          Administrator, in its sole discretion, may approve or disapprove any
          payment schedule requested at the time of onset of Disability;
          provided further that no payment shall be made until the first
          business day of the first calendar quarter that begins after the date
          of Disability; and provided further that, if at the time of the onset
          of the Disability payment has commenced pursuant to paragraph (a),
          above, or the preceding provisions of this paragraph (b), such
          payments shall continue according to the schedule on which they were
          then being paid.

     (3)  Death. If a Participant dies before receiving any or all of the
          balance in the Participant's account, the entire balance in the
          Participant's account shall be paid as soon as practicable after the
          Participant's death in a lump sum to the beneficiary designated by the
          Participant in accordance with Section 3.04, or, if there is no such
          beneficiary, to the Participant's estate.

5.04.    Accelerated Distributions.

(a)  Hardship.  Upon request, the Plan Administrator may permit the payment of
     all or part of a Participant's account if the Plan Administrator, in its
     sole discretion, determines that the Participant has incurred unusual,
     extraordinary expenses or hardship caused by events beyond the
     Participant's control, such as accident or illness.  The amount that may be
     withdrawn shall be limited to the amount reasonably necessary to relieve
     the hardship or financial emergency upon which the request is based.  The
     Plan Administrator may require a Participant who requests a payment under
     this subsection (a) to submit such evidence as the Plan Administrator, in
     its sole discretion, deems necessary or appropriate to substantiate the
     circumstances upon which the request is based.

(b)  Other.  At any time, a Participant may elect that 94% of all (or a
     designated portion of) his account balance shall be paid to him 61 days
     following the filing of such an election; provided that the Plan
     Administrator may approve or disapprove such election in its sole
     discretion.  If a Participant receives a payment pursuant to this
     subsection (b), the remaining 6% of the Participant's entire account
     balance (or the designated portion thereof) shall be permanently forfeited
     and shall not be paid to, or in respect of, the Participant.

5.05.    Forfeiture of Rights.

     A Participant who is terminated as a result of conviction of a felony, who
misuses or misappropriates Company assets or confidential information of the
Company, or violates other forfeiture provisions as determined by the Plan
Administrator either while employed by the

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

  Genuity Inc. Executive Deferral Plan                                   Page 15
<PAGE>

Company or following a separation from service with the Company, may in the
discretion of the Plan Administrator forfeit all rights to any payments under
the Plan that would otherwise be payable to the Participant or his beneficiaries
on or after the initial date of such action by the Participant.  A Participant
shall not be deemed to have incurred a Termination for Cause or to have misused
Company assets or confidential information of the Company within the meaning of
this subsection (a) unless and until there shall have been delivered to him a
notice from the Plan Administrator (after reasonable notice to the Participant
and an opportunity for the Participant, together with counsel, to be heard
before the Plan Administrator), finding that the Participant has misused Company
assets or confidential information of the Company or engaged in the conduct set
forth in the definition of Termination for Cause and specifying the particulars
thereof in detail.

                         ARTICLE VI.    MISCELLANEOUS

6.01.    Plan Administration.

(a)  In General.  Except to the extent the Plan specifically provides otherwise:
     (i) the Plan Administrator shall have the discretionary authority to
     interpret the Plan and to decide any and all matters arising under the
     Plan, including without limitation the right to determine eligibility for
     participation, benefits, and other rights under the Plan; the right to
     determine whether any election or notice requirement or other
     administrative procedure under the Plan has been adequately observed; the
     right to determine the proper recipient of any distribution under the Plan;
     the right to remedy possible ambiguities, inconsistencies, or omissions by
     general rule or particular decision; the right to make factual findings
     under the Plan; and the right otherwise to interpret the Plan in accordance
     with its terms; and (ii) the Plan Administrator's determination on any and
     all questions arising out of the interpretation or administration of the
     Plan shall be final, conclusive, and binding on all parties.

(b)  Plan Amendment and Termination.  The Board may amend, suspend, or terminate
     the Plan at any time.  Upon termination of the Plan, all amounts deferred
     before the date of termination, and any rights to payment with respect to

     the Plan.

(c)  The Company reserves the right to charge fees to Participants for set-up
     and/or maintenance of deferral accounts.

6.02.    Appeals Procedure.

     A claimant who has been denied a claim for benefits, in whole or in part,
may, within a period of 60 days following his receipt of the denial, request a
review of such denial before the Plan Administrator by filing a written notice
with the Plan Administrator.  In connection with an appeal, the claimant (or his
authorized representative) may review pertinent documents and may submit
evidence and arguments in writing to the Plan Administrator.  The Plan
Administrator may decide the questions presented by the appeal and shall issue
to the claimant a written notice setting forth: (1) the specific reasons for the
decision and (2) specific reference to the pertinent Plan provisions on which
the decision is based.  The notice shall be issued within a period of time not

additional 60 days commencing at the end of the initial 60-day period.  Written
notice of any such extension shall be provided to the claimant prior to the
expiration of the initial 60-day period.  The decision of the Plan Administrator
shall be final and conclusive.

6.03.    Rights Not Assignable.

     A Participant's rights and interest under the plan may not be assigned or
transferred.  In the case of any former Participant's death, payment, if any,
under the Plan shall be made to the Participant's surviving spouse or designated
beneficiary in accordance with the provisions of the Plan.  However, the
immediately preceding sentences shall not apply with respect to an order which
satisfies the requirements for a qualified domestic relations order set forth in
Section 206(d)(3)(B)(i) of the Employee Retirement Income Security Act of 1974,
as amended, which is issued with respect to a Participant's right or interest
under the Plan, and benefits shall be payable to the alternate payee designated
in the order in accordance with the terms and conditions thereof.

6.04.    Inability to Locate Participants and Beneficiaries.

     Each Participant or beneficiary entitled to receive payment under the Plan
shall keep the Plan Administrator advised of his current address.  If the Plan
Administrator is unable for a period of 36 months to locate a Participant or
beneficiary to whom a payment is due under the Plan, commencing with the first
day of the month as of which such payment first comes due, the total amount
payable to such Participant or beneficiary shall be forfeited.  Should such a
Participant or beneficiary contact the Plan Administrator requesting payment
thereafter, the Plan Administrator shall, upon satisfaction of its requests for
any corroborating documentation, restore and pay the forfeited payment in a lump
sum, the value of which shall not be adjusted to reflect any interest or other
type of investment earnings or gains for the period of forfeiture.

6.05.    Withholding Taxes.

     The Plan Administrator may make any appropriate arrangements to deduct from
all Annual Deferrals and payments hereunder any taxes that the Plan
Administrator reasonably determines to be required by law to be withheld from
such Annual Deferrals and payments.

6.06.    Certain Rights Reserved.

     Nothing in the Plan shall confer upon any employee of the Company or other
Person the right: (1) to continue in the employment or service of the Company or
affect any right that the Company may have to terminate the employment or
service of (or to demote or to exclude from future participation in the Plan)
any such employee or other Person at any time for any reason; (2) to participate
in the Plan; or (3) to receive an annual base salary of any particular amount.

6.07.    Severability.

     If any provision of the Plan is held unlawful or otherwise invalid or
unenforceable in whole or in part, such unlawfulness, invalidity, or
unenforceability shall not affect any other provision of the Plan or part
thereof, each of which shall remain in full force and effect.  If the making of
any payment or the provision of any other benefit required

under the Plan is held unlawful or otherwise invalid or unenforceable, such
unlawfulness, invalidity, or unenforceability shall not prevent any other
payment or benefit from being made or provided under the Plan, and, if the
making of any payment in full or the provision of any other benefit required
under the Plan in full would be unlawful or otherwise invalid or unenforceable,
then such unlawfulness, invalidity, or unenforceability shall not prevent such
payment or benefit from being made or provided in part, to the extent that it
would not be unlawful, invalid, or unenforceable, and the maximum payment or
benefit that would not be unlawful, invalid, or unenforceable shall be made or
provided under the Plan.

6.08.    Titles and Headings Not to Control.

     The titles to Articles and the headings of Sections, subsections,
paragraphs, and subparagraphs in the Plan are placed herein for convenience of
reference only and, as such, shall have no force or effect in the interpretation
of the Plan.

6.09.    Governing Law.

     To the extent not preempted by federal law, the provisions of the Plan will
be construed and enforced in accordance with the laws of the Commonwealth of
Massachusetts, excluding any conflicts or choice of law rule or principle that
might otherwise refer construction or interpretation of this provision to the
substantive law of another jurisdiction.

     participate in the Plan and receive Awards hereunder.

5.   ADMINISTRATION

     (a)  The Plan and all Awards granted pursuant thereto shall be administered
          by the Committee. The Committee shall periodically determine, in its
          sole discretion, the Employees who shall participate in the Plan and
          the terms of the Awards to be granted to Participants. All questions
          of interpretation and administration with respect to the Plan and
          Awards shall be determined by the Committee in its sole and absolute
          discretion, and its determinations shall be final and binding upon all
          parties.

     (b)  The Committee may delegate its authority under subsection (a), above,
          to persons other than its members to the extent it deems such action
          advisable. Any person to whom the Committee has delegated authority
          under subsection (a), above, may receive Awards only if the Awards are
          granted directly by the Committee without delegation.

     (c)  The Committee may, in its sole discretion, promulgate general
          regulations and guidelines governing the administration of the Plan
          and the Awards granted hereunder. The Committee also may establish
          regulations governing the deferred payment of Awards and may determine
          that deferred payments shall accrue interest at a rate or rates
          determined by the Committee and/or that deferred payments shall be
          deemed to be invested in hypothetical investments.

6.   AWARDS

     (a)  All Awards under the Plan shall be granted upon terms approved by the
          Committee. However, no Award shall be inconsistent with the terms of
          the Plan or fail to satisfy the requirements of applicable law.

     (b)  Each Award shall relate to a designated Plan Year.

     (c)  No Award shall relate to more than one Plan Year.

<PAGE>

     (d)  The maximum Award per Participant for a Plan Year shall not exceed two
          million dollars ($2,000,000). The Committee may reduce, but may not
          increase, the maximum Award for any Participant.

7.   LIMITATIONS ON AWARDS

     (a)  Unless otherwise determined by the Committee, in its sole discretion,
          a Participant who is not an Employee of the Company or a Related
          Entity at all times during the Plan Year and as of the payment date
          set by the Committee pursuant to Section 8(a) hereof shall have no
          right to receive an Award for that Plan Year.

     (b)  The Committee may, in its discretion, authorize payment to a
          Participant of less than the Participant's maximum Award and may
          provide that a Participant will not receive any payment with respect
          to an Award. In exercising its discretion, the Committee shall
          consider such factors as it considers appropriate. The Committee's
          decision shall be final and binding upon any person claiming a right
          to a payment under the Plan.

     (c)  No Award shall be assignable or transferable other than by will or by
          the laws of descent and distribution. During the Participant's
          lifetime, an Award may be received only by the Participant or by the
          Participant's guardian or legal representative.

8.   PAYMENT OF AWARDS

     (a)  All payments of Awards shall be made on a date prescribed by the
          Committee unless the Participant is eligible and has elected to defer
          payment in accordance with the Genuity Inc. Executive Deferral Plan.

     (b)  Awards shall be paid only in cash.

9.   AMENDMENT OR TERMINATION OF THE PLAN

     The Board may, from time to time, alter, amend, suspend or terminate the
     Plan as it shall deem advisable, subject to any requirement for shareholder
     approval imposed by applicable law.  The termination of the Plan shall not
     cause any previously granted Awards to terminate.  After the termination of
     the Plan, any previously granted Awards shall remain in effect and shall
     continue to be governed by the terms of the Plan and the Awards. This
     Section applies regardless of whether the termination of the Plan occurs
     pursuant to Section 2 hereof or pursuant to this Section 9.

10.  NO REQUIRED SEGREGATION OF ASSETS

     Neither the Company nor any Related Entity shall be required to segregate
     any assets that may at any time be represented by Awards pursuant to the
     Plan.

11.  RIGHT OF DISCHARGE RESERVED

     Neither the Plan nor any Award shall guarantee any Employee continued
     employment with the Company or a Related Entity or guarantee the grant of
     future Awards.  Either the Company or the Employee may terminate the
     employment relationship at any time and for any reason.

12.  NATURE OF PAYMENTS

     All Awards made pursuant to the Plan are in consideration of services for
     the Company or the Related Entities. Any gain realized pursuant to Awards
     under the Plan constitutes a special incentive payment to the Participant
     and shall not be taken into account as compensation for purposes of any of
     the employee benefit plans of the Company or any Related Entity except as
     may be determined by the Board or by the board of directors of the
     applicable Related Entity.

13.  SEVERABILITY

     If any provision of the Plan shall be held unlawful or otherwise invalid or
     unenforceable in whole or in part, the unlawfulness, invalidity, or
     unenforceability shall not affect any other provision of the Plan or part
     thereof, each of which shall remain in full force and effect.

14.  GOVERNING LAW

     To the extent not preempted by federal law, the provisions of the Plan will
     be construed and enforced in accordance with the laws of the Commonwealth
     of Massachusetts, excluding any conflicts or choice of law rule or
     principle that might otherwise refer construction or interpretation of this
     provision to the substantive law of another jurisdiction.
