 holders of the Notes will be required to include such OID in gross income for
  U.S. federal income tax purposes on a constant yield to maturity basis, in
     advance of the receipt of the cash payments to which such income is
attributable. See "Certain United States Federal Income Tax Consequences." The
price to investors for the Notes shown below represents a yield to maturity of
         % per annum (computed on a semi-annual bond equivalent basis).

  The Notes will not be redeemable at the option of the Company prior to     ,
2003, except that until      , 2001, the Company may redeem, at its option, up
 to 35% of the principal amount of the Notes at the redemption price set forth

   defined) thereof, plus accrued and unpaid interest, if any, to the date of
                                  repurchase.

 The Notes will be senior unsecured obligations of the Company, ranking pari
passu in right of payment with all existing and future senior unsecured
 indebtedness of the Company, and will be senior in right of payment to all
 future subordinated indebtedness of the Company. As of March 31, 1998, after
giving effect to the Offerings (as defined) and the application of the proceeds
  therefrom, the Company would have had outstanding $     million of senior

Optic Network, Inc. and its subsidiaries, including predecessor companies,
except where the context otherwise requires. Certain terms used herein are
defined in the Glossary beginning on page G-1.


                                  THE COMPANY

     The Company is a facilities-based provider of technologically advanced,
high-bandwidth, fiber optic transmission capacity for communications carriers
on local loop, inter-city and interstate facilities. The Company is currently
expanding its fiber optic network, the NEON system, to encompass approximately
1,000 route miles, or approximately 80,000 fiber miles, concentrated in the
northeastern United States, including New York and New England (the
"Northeast"). The Company believes that the Northeast, which in 1996
represented a $29.3 billion telephony services market and which has one of the
highest population densities and concentrations of businesses, universities,
phone lines, personal computers and television sets in the country, is a region
characterized by significant and growing demand for broadband communications
infrastructure. The Company is constructing the NEON system utilizing primarily
electric utility rights-of-way ("ROWs"), which allow the Company to provide
secure fiber optic capacity at competitive prices with access to virtually any
location where the local utility provides electrical service. The Company is
using advanced fiber optic technology in the NEON system, including non-zero
dispersion shifted fiber, dense wave division multiplexing optronics and SONET
four-fiber ring self-healing technology, to allow the Company's carrier
customers to meet the demand for reliable, high-bandwidth voice, data and video
transmission capacity in the Northeast. For example, a pair of fiber optic
strands on the NEON system can transmit up to approximately 10 gigabits of data
per second, or the equivalent of approximately 129,000 simultaneous voice
conversations.

     The Company has already completed and currently operates fiber optic
routes from Hartford, Connecticut to Springfield, Massachusetts and from
Nashua, New Hampshire to Portland, Maine, totaling approximately 212 route
miles, or approximately 13,700 fiber miles. The Company is currently
engineering or constructing additional routes in New York, Connecticut,
Massachusetts and New Hampshire to create a continuous fiber optic link between
White Plains, New York and Portland, Maine with access into and around Boston,
Massachusetts and numerous other major cities in the Northeast. These
additional routes are expected to be substantially completed in 1998 and will
add approximately 380 route miles, or approximately 30,800 fiber miles, to the
NEON system. The Company is also planning to complete further expansion routes
in 1999 connecting New York City, Providence and other metropolitan areas to
the NEON system. The completion of routes under construction and currently
planned will enable the NEON system to connect more than 540 cities and towns
in six states and pass more than 200 points-of-presence ("POPs"), tandem
switches and central offices, which the Company believes serve over 18 million
people and over 470,000 businesses.

     Commencing in September 1994, the Company entered into a series of ROW
agreements with Northeast Utilities Service Company, a subsidiary of Northeast
Utilities ("NU"), the largest electric utility service provider in New England,
serving over 1.7 million customers in Connecticut, Massachusetts and New
Hampshire, to build fiber optic facilities utilizing NU's transmission and
distribution infrastructure, including utility towers, poles, underground ducts
and urban conduit systems. In January 1997, the Company entered into a similar
ROW agreement with the Central Maine Power Company ("CMP"), the largest
electric utility service provider in Maine, serving over 500,000 customers, to
build fiber optic facilities utilizing CMP's transmission and distribution
infrastructure. NU and CMP have also financed substantially all of the
construction and operations of the NEON system to date and currently
beneficially own (prior to the sale of shares in the Equity Offering) 41.37%
and 53.53%, respectively, of the Company's capital stock.

     The Company has pursued a strategy of establishing relationships with
electric utilities and building the NEON system utilizing primarily electric
utility ROWs. The Company believes that the use of such ROWs provides


                                       3
<PAGE>

significant advantages, including: (i) potentially ubiquitous inter-city and
intra-city coverage in the local electric utility's service territory,
including throughout downtown areas and directly into buildings, (ii) use of
existing electric transmission infrastructures, including towers, poles, ducts
and conduits, to achieve faster, less costly installation, (iii) generally more
secure and reliable routes than other ROWs, including railroad beds, streets
and highways, (iv) highly desirable redundant and geographically diverse fiber
optic routes for communications carriers and (v) establishment of an extensive
ROW network through negotiation with relatively few parties, rather than with
numerous parties such as municipalities, transit authorities and governmental
agencies.


     The Company currently intends to target only communications carriers as
customers, rather than end-users of telecommunications services. The Company
believes that this strategy allows it to: (i) maximize the Company's
opportunities to sell its capacity regardless of the end-user's selection of a
retail provider, (ii) avoid the significant initial and ongoing investment
required in selling, marketing and providing services to end-users, (iii)
attract carrier customers that may be reluctant to contract with a direct
competitor, (iv) generate revenues quickly from carriers that are easily
identifiable and require large amounts of fiber optic capacity, and (v) lock in
relatively secure long-term revenue streams from customers that are generally
more creditworthy than end-users. Carrier customers typically lease fiber optic
capacity under multi-year contracts with which they enhance or develop their
own communications networks as a cost-effective alternative to constructing
their own infrastructure or purchasing measured services from other carriers
with whom they may compete. Carriers targeted by the Company include a broad
range of communication companies such as incumbent local exchange carriers
("ILECs"), competitive local exchange carriers ("CLECs"), long distance
companies/interexchange carriers ("IXCs"), paging, cellular and PCS companies,
cable television companies and Internet service providers ("ISPs"). Currently,
the Company has contracts with Brooks Fiber Properties, Inc. ("Brooks Fiber")
(now owned by WorldCom, Inc. ("WorldCom")), Teleport Communications Group Inc.
("Teleport") (expected to be acquired by AT&T Corp. ("AT&T")), MCI
Communications Corporation ("MCI") (expected to be acquired by WorldCom),
Sprint Corporation ("Sprint") and Global NAPs, Inc., a regional ISP.


     The Company intends to offer its carrier customers leases of both dark
fiber (fiber optic transmission lines leased without optronics equipment
installed by the Company) and lit fiber (fixed amounts of capacity, such as
DS-1, DS-3, OC-3, OC-12, OC-48 and higher, on fiber optic transmission lines
that use the Company's optronics equipment) at fixed-cost pricing and over
multi-year lease terms. The Company intends to lease approximately one-third of
the available fibers in the NEON system as dark fiber and one-third as lit
fiber. In addition, the Company plans to reserve approximately one-third of its
available fibers for future services that the Company may provide to capitalize
on future technological advances or changes in the marketplace that the Company
expects to occur in the communications industry. Because of the geographic
flexibility and virtual ubiquity of the electric utility ROWs used in
construction of the NEON system, the Company expects that it will be able to
provide fiber optic connectivity for its carrier customers to and from
virtually any location in the NEON service territory, including intra-city
local loop facilities, inter-city long-haul or short-haul facilities, or a
combination of both.


History of the Company

     The Company was incorporated in 1989 in Massachusetts under the name
"FiveCom, Inc." to develop fiber-optic networks in secondary and tertiary
markets in the Northeast. Prior to 1994, the Company was the managing general
partner of a venture which built a competitive access provider ("CAP") network
in Springfield, Massachusetts and also built several small private networks in
eastern Massachusetts. In February 1994, the Company sold its interest in the
Springfield network to Brooks Fiber. Following this sale, the Company expanded
its business strategy to include intra-LATA and long distance facilities using
electric utility ROWs and changed its focus to target carrier customers rather
than end users. Commencing in September 1994, the Company entered into the NU
Agreements, pursuant to which the Company obtained ROWs in the service
territories of NU and its subsidiaries. In 1996, the Company raised
approximately $16.7 million from private placements of equity securities to
MaineCom Services ("MaineCom"), an affiliate of CMP, and Mode 1 Communications,
Inc. ("Mode 1"), an affiliate of NU. In January 1997, the Company entered into
the CMP Agreement, under which the Company obtained ROWs in CMP's service
territory, and raised an additional $2.6 million from CMP and other investors
in a private equity financing. In 1998 the Company was reincorporated in
Delaware under the name "NorthEast Optic Network, Inc." See
"Business--Reorganization."

Market Opportunity

     The Company believes that there is a significant demand for high-bandwidth
communications services and a limited supply of technologically advanced dark
and lit fiber optic facilities in the Northeast to meet such demand. The
Company believes the needs of communications carriers for advanced,
high-bandwidth voice, data and video transmission capacity will increase over
the next several years due to various factors, including:

     Rapid Growth of Communications Traffic. The Company believes that total
telephony service revenue in the United States grew by approximately 9%
annually from 1992 to 1996, to $222.3 billion. Data traffic service grew by 28%
from 1996 to 1997 to $16 billion and is projected to grow by 38% to $22.1
billion in 1998. Much of this growth in data traffic is attributable to
increased Internet traffic and its corresponding demands for increased data
communications bandwidth. For example, the number of Americans using the
Internet is estimated to have grown from fewer than five million in 1993 to as
many as 62 million by the end of 1997. The Company believes that the growth of
communications traffic in the Northeast will be enhanced by the high population
density, income and education levels, number of phone lines per household and
other favorable demographic characteristics of the region. With its advanced
fiber optic transmission capacity, the Company believes that it will be
well-positioned to capitalize on this growth.

     Capacity Required by New Entrants. Competition and deregulation are
attracting new entrants to the telecommunications market. The
Telecommunications Act of 1996 (the "1996 Act") allows the Regional Bell
Operating Companies ("RBOCs") to enter the long distance business upon meeting
certain competitive conditions and also eliminates certain barriers to entry in
the local exchange market. The 1996 Act also enables other entities, including
entities affiliated with power utilities and ventures between ILECs and cable
television companies, to provide a wider range of telecommunications products
and services. The Company believes that the deregulation of various
telecommunications markets will lead to an increase in the number of
telecommunications providers needing fiber optic transmission capacity as more
parties choose to compete. The Company believes that many carrier customers
will choose to lease fiber optic capacity from facilities providers such as the
Company to enhance or develop their own communications networks as a lower-cost
alternative to constructing their own infrastructure or purchasing measured
services from other carriers. The Company believes that the NEON system will
provide a cost-effective alternative for market entrants in a number of
communications industry segments, including ILECs, CLECs, IXCs, wireless
companies, cable companies and ISPs.

     Need for Redundant Routing and Geographic Diversity of ROWs. Carriers
require redundant paths throughout their networks to provide reliability in the
event of an equipment failure, break in one of their fiber lines or other
outage. In order to ensure the required redundancy, carriers typically build,
swap or lease capacity along fiber routes that do not share a common point of
potential failure. In the Northeast, however, there are relatively few pre-
assembled ROWs available to support new telecommunications infrastructure. As a
result, many carriers are unable to establish secure redundant routing when all
the carriers' routes run within the same ROWs. In the event such a common ROW
were to be damaged or cut, the consequences would be severe for the carriers
and their customers. This lack of geographic diversity of fiber optic routes in
the Northeast has created a substantial need for network capacity on new and
alternative ROWs, such as those offered by the Company.

     Expected Upgrades to Older Communications Networks. Many of the fiber
optic networks currently operated by existing carriers in the Northeast were
constructed prior to 1990, using asynchronous, non-SONET ring architecture and
earlier generation fiber that cannot optimally deploy dense wave division
multiplexing ("DWDM") optronics for high capacity transmission. The Company
believes that these carriers will need to improve or replace parts of their
networks to complete the SONET ring architecture and also add more high
capacity fiber optic transmission lines to remain competitive in the future. In
addition, the Company believes that approximately 92% of the RBOCs' networks
currently are comprised of copper cable located on antiquated infrastructure.
The RBOCs will likely need to replace or upgrade their networks to remain
competitive and satisfy their customers' increasing demand for reliable,
high-bandwidth capacity in the coming years. The Company believes that carriers
with older, more limited networks will seek cost-effective and expedient
solutions when faced with the decision to lease, buy or build fiber optic
capacity which could result in increased demand for the Company's fiber optic
capacity.

     Accommodation of Multimedia and Other New Applications. The Company
believes that additional transmission capacity and faster response times will
be required to accommodate the needs of multimedia (voice,


                                       5
<PAGE>

data and video) and other potential high-bandwidth applications, including the
deployment of corporate intranets and wide area networks, and the use of the
telecommunications infrastructure for providing cable television and other
entertainment services. In addition, the Company's SONET technology and
high-bandwidth fiber optic capacity support advanced communications
applications, such as Frame Relay, ATM and Internet Protocol ("IP") platforms.
The Company believes that these capacity-intensive requirements will create
significant demand for its high quality, high-bandwidth fiber optic capacity.

     Carriers' Desire for Low-Cost Local and Regional Transport. The Company
believes that it has an opportunity to fill the needs of the predominant
interstate carriers that are building or have completed their backbone networks
to most of the Northeast's key Local Access Transport Areas ("LATAs").
Generally, an IXC constructs a network with trunk lines terminating into tandem
switches in LATAs. To get from the tandem switch to the end-user, or vice
versa, IXCs typically pay to a local exchange carrier ("LEC") access and egress
charges, which often comprise the largest component of the IXCs' transmission
costs. For this reason, IXCs are seeking less costly, alternative local access
within LATAs. One alternative for the IXCs is to carry their traffic deeper
into the region's telecommunications base and to hand off their traffic at a
LEC host switch, which is located much closer to the end-user than the tandem
switch, or to terminate their traffic directly at the customer's premises.
Similarly, the Company believes that LECs with inter-LATA traffic, including
the RBOCs when they are permitted to provide long-distance traffic, desire to
minimize the transportation costs imposed by the IXCs and are seeking lower
cost, alternative regional transport. The NEON system, which will connect into
and around numerous cities and towns in the Northeast, can provide such local
access and regional transport.


Business Strategy

     The Company's objective is to become the preferred facilities-based
provider of fiber optic network capacity in the Northeast. The following are
the key elements of the Company's strategy to achieve this objective:

     Leverage Electric Utility ROWs.  The Company is pursuing a strategy of
building the NEON system utilizing primarily electric utility ROWs, which the
Company believes provide significant competitive advantages compared to
alternative ROWs in the Northeast such as railbeds and highways. Using electric
utility ROWs, the Company can provide fiber optic connectivity for its carrier
customers to and from virtually any location in the utilities' service
territory, including throughout downtown areas and directly into buildings. The
Company also intends to utilize existing, pre-assembled electric utility
transmission infrastructure, including towers, poles, ducts and conduits for
faster, less costly installation. In addition, since electric utility ROWs are
generally more secure than other ROWs and provide valuable geographic route
diversity for carriers, the Company can offer its customers highly reliable
primary and redundant network capacity. In addition to the Company's existing
ROW agreements with NU and CMP, the Company is currently pursuing additional
agreements with other utilities in adjoining territories to expand the
Company's network footprint and gain access to further ROWs through negotiation
with relatively few parties, rather than numerous municipalities, transit
authorities and governmental agencies.

     Target Carrier Customers. The Company intends to target communications
carriers as customers, rather than end-users of telecommunications services.
This enables the Company to maximize its opportunities to sell its capacity
regardless of the end-user's selection of a retail provider and to attract
carrier customers that may be reluctant to purchase services from a direct
competitor that serves the same retail market. Carrier customers are also
easily identifiable, which allows the Company to focus its sales and marketing
and customer services efforts and avoid the significant initial and ongoing
investment required to attract and retain numerous retail customers. In
addition, the Company believes that it can generate revenues more quickly from
carrier customers, which are generally more creditworthy than end-users,
require large amounts of fiber optic capacity and are more likely to make
long-term capital commitments in advance of the provision of services. To date,
the Company has entered into contracts with five carriers, including Brooks
Fiber/  WorldCom, Teleport/AT&T, MCI/WorldCom, Sprint and Global NAPs, Inc., a
regional ISP.

     Reduce Construction and Operating Costs. The Company is reducing the
construction and operating costs of the NEON system in order to offer its
customers competitive prices while maximizing its operating margins and return
on investment. The Company is using primarily pre-assembled electric utility
transmission and distribution infrastructure, including towers, poles, ducts
and conduits, in the construction of the NEON system, which reduces the need to
obtain local permits, conduct surveys, cut tracks, install conduits and ducts
and erect towers and poles prior to installation. In


                                       6
<PAGE>

addition, the Company's electric utility ROWs provide easy and safe access to
the fiber cable for low cost maintenance and repair. The Company is also
installing high fiber count cable in the NEON system--64 to 96 fiber optic
strands per cable in the routes currently under construction and up to 144 to
432 fiber optic strands on future installations, depending on the anticipated
demand for a particular route. This high fiber count reduces the Company's
fiber cost per mile and provides reserve capacity, which will reduce the cost
of providing additional services in the future. The Company's newly-constructed
network also provides significant operating and maintenance cost advantages
because of the high quality, advanced fiber optic technology utilized by the
NEON system.

     Build a Reliable, Technologically Advanced Network. The Company believes
that the characteristics of its network will allow it to meet its customers'
demands for reliability and high capacity. The Company is constructing the NEON
system utilizing bi-directional, self-healing SONET four-fiber ring
architecture on primarily electric utility ROWs, which allow for enhanced
physical security and more geographic flexibility than other ROWs. The Company
uses both non-zero dispersion shifted Truewave[RegTM] fiber and conventional
single-mode fiber manufactured by Lucent Technologies Inc., which the Company
believes to be the highest quality fiber optic cable available. The Company is
also using Nortel's DWDM optronics and forward error correction technology at
high optical carrier ("OC") levels that enable the highest commercially
available transmission capacity (OC-192) and data integrity level (10-15 Bit
Error Rate). The NEON system can also accommodate advanced communications
applications such as Frame Relay, ATM and IP.

     Focus on High Demand Northeast Market. The Northeast is one of the most
densely-populated regions of the United States. The Company believes that the
Northeast market, which in 1996 represented a $29.3 billion telephony services
market and which has one of the highest concentrations of businesses,
universities, phone lines, personal computers and television sets in the
country, is a region characterized by significant and growing demand for
broadband communications infrastructure. The Northeast market is dependent in
part upon antiquated communications infrastructure currently lacking sufficient
fiber optic capacity, route diversity and redundancy. The Company's strategy is
to focus on serving the present and future needs of this market by constructing
and operating a technologically advanced network offering (i) more capacity,
(ii) enhanced capabilities, such as SONET ring architecture and route
diversity, and (iii) near-ubiquitous coverage.

     Leverage Management Experience. The Company's management team includes
individuals with significant experience in the telecommunications and utility
industries which will be important in the buildout of the NEON system. Victor
Colantonio, the Company's founder and President, has 25 years of experience in
the telecommunications industry having previously served as President of
International Communications Services Corp. and Murray International Inc.
providers of network services to AT&T, Southern New England Telecommunications
Corporation ("SNET") and Sprint, among others. The Company's Chairman and Chief
Executive Officer, Richard Crabtree, has 27 years of utility experience
including serving as Chief Financial Officer to CMP. William Fennell, the
Company's Chief Financial Officer and Treasurer, held several positions at GTE
over 16 years before becoming Chief Financial Officer of Philips Electronics
Group of North America. James Mack, the Company's head of sales, has worked in
the telecommunications industry since 1966 having held various sales positions
at Bell Atlantic and NYNEX. The Company's head of operations, Michael Musen,
has spent 18 years in telecommunications having previously worked at a provider
of network systems.

     Leverage Utility Relationships. The Company intends to leverage its
relationships with NU and CMP. The Company directly benefits from these
relationships for the following reasons: (i) the Company believes relationships
with electric utilities enhance the Company's credibility with large carrier
customers and facilitate new customer contracts with such carriers, (ii) the
Company outsources substantially all of its engineering and design, maintenance
and repair requirements to NU and CMP, thereby increasing the Company's mission
critical preparedness and the reliability of the Company's network and
enhancing the Company's ability to respond to emergency repair needs, (iii) NU
and CMP have significant resources and experience in the engineering and
construction of large transmission and distribution networks and (iv) the
Company's experience with NU and CMP creates opportunities to establish
relationships with other electric utility companies. The Company is currently
in the process of developing relationships with additional electric utilities.

     The Company's principal executive offices are located at 391 Totten Pond
Road, Suite 401, Waltham, Massachusetts 02154, and its telephone number is
(781) 890-6868.

years in the three-year period ended December 31, 1997 and as of December 31,
1997 have been derived from the Consolidated Financial Statements of the
Company, which have been audited by Arthur Andersen LLP, independent public
accountants. The selected consolidated financial data for each of the
three-month periods ended March 31, 1997 and 1998 and as of March 31, 1998 have
been derived from the unaudited consolidated financial statements of the
Company, which have been prepared on the same basis as the Consolidated
Financial Statements of the Company and, in the opinion of management, reflect
all normal recurring adjustments necessary for a fair presentation of the
financial position and results of operations for such periods and as of such
dates. The results for the three months ended March 31, 1998 are not
necessarily indicative of the operating results to be expected for the entire

(1) EBITDA is defined herein as net loss before interest income (expense), loan
    commitment fees, provision for (benefit from) income taxes, depreciation
    and amortization and is presented because it is commonly used by certain
    investors and analysts to analyze and compare a company's operating
    performance and to determine


                                       11
<PAGE>

   a company's ability to incur and service debt. EBITDA should not be
   considered in isolation from, or as a substitute for, net income, cash flow
   from operating activities or other consolidated income or cash flow
   statement data prepared in accordance with generally accepted accounting
   principles or as a measure of profitability or liquidity.

(2) Adjusted to give effect to the Reorganization. In connection with the
    Reorganization, the Company recorded an intangible asset of $48,092,600 to
    reflect the Company's acquisition of NU's minority interest in
    subsidiaries (NECOM LLC and FiveCom LLC), in accordance with AICPA
    Accounting Interpretation 39 to APB Opinion No. 16, Business Combinations
    (AIN-39). The intangible asset will be amortized over 30 years, reflecting
    assignment of value to goodwill to the rights-of-way, which have 30 year
    terms. If the Reorganization had occurred as of January 1, 1997 the pro
    forma impact on the Company's Statement of Operations for the year ended
    December 31, 1997 would reflect amortization of $1,603,087, a net loss of
    $(2,563,113) and a loss per share of $      . The pro forma impact on the
    Company's Statement of Operations for the quarter ended March 31, 1998
    would reflect amortization of $400,772, a net loss of $(693,926) and a
    loss per share of $      .

(3) Adjusted to give effect to (i) the Offerings and the application of the
    estimated net proceeds therefrom, (ii) the conversion of the Company's
    Preferred Stock into an aggregate of        shares of Common Stock upon
    the closing of the Offering and (iii) the Reorganization.

(4) Minority interest consists of the interests of members other than CMP in
    FiveCom LLC, NECOM LLC and FiveCom of Maine LLC. Changes in minority
    interest reflect such other members' capital adjusted by their portion of
    the net loss.

(5) For purposes of calculating the ratio of earnings to fixed charges: (i)
    earnings consist of loss before income tax benefit, plus fixed charges,
    excluding capitalized interest, and (ii) fixed charges consist of interest
    expense capitalized interest, plus amortization of deferred financing
    costs. For the years ended December 31, 1995, 1996, and 1997 and for the
    three months ended March 31, 1997 and 1998, the Company's earnings were
    insufficient to cover fixed charges by approximately $(431,579),
    $(1,206,438), $(3,123,787), $(376,612) and $(878,731), respectively. For
    the year ended December 31, 1997 and for the three months March 31, 1998,
    on a pro forma basis after giving effect to the Debt Offering, the
    Company's earnings would have been insufficient to cover fixed charges by
    approximately $      and $      , respectively.

                                 RISK FACTORS

     In addition to the other information contained in this Prospectus, the
following factors should be carefully considered by prospective investors when
evaluating an investment in the securities offered hereby. This Prospectus
contains certain forward-looking statements that involve risks and
uncertainties. The cautionary statements contained in this Prospectus should be
read as being applicable to all related forward-looking statements wherever
they appear in this Prospectus. The Company's actual results could differ
materially from those discussed here. Important factors that could cause or
contribute to such differences include those discussed below, as well as those
discussed elsewhere in this Prospectus.


Limited History of Operations; Negative Cash Flow

     Although the Company has conducted business since 1989, the Company's
current business has only a very limited history. As a facilities-based
provider of fiber optic transmission capacity, the Company is a development
stage company in the process of constructing the NEON system throughout the
Northeast. Although limited portions of the NEON system are currently
operational, those portions represent less than 21% of the route miles of the
NEON system as currently planned, and until the NEON system is substantially
completed, the Company does not expect to begin to realize any substantial
revenues. See "--Risks Associated with Completing the NEON System." Prospective
investors, therefore, have no meaningful historical operating or financial
information about the Company's current business upon which to base an
evaluation of the Company's performance or their investment in the securities
offered hereby. The Company does not expect to achieve substantial completion
of the NEON system as currently planned until the end of 1999. The Company's
future operating results will fluctuate annually and quarterly due to several
factors, some of which are outside the control of the Company. These factors
include the cost of construction of the NEON system (including any
unanticipated costs associated therewith), the availability of ROWs, the cost
and timely availability of equipment and construction contractors, pricing
strategies for its services, changes in the regulatory environment, changes in
telecommunications technology and changes in general and local economic
conditions. In addition, the extent of the demand for the Company's services
cannot be estimated with any degree of certainty. See "--Risks Associated with
Implementing the Company's Strategy."

     In addition, the development of the Company's business, the completion of
the NEON system and the development of its services and customer base will
require significant expenditures, most of which will need to be made before the
Company is able to offer services over substantially all of the NEON system.
These expenditures, together with associated operating expenses, will adversely
impact operating cash flow and profitability until an adequate customer base is
established. To date, the Company has expended substantial amounts on
construction of the NEON System. Such cash expenditures have been funded by
proceeds from the Company's financing activities. Accordingly, the Company's
operations have resulted in negative cash flow. Moreover, the Company expects
to continue generating negative cash flow from operations through at least
2000. There can be no assurance that the Company will not need to obtain
additional financing to complete the NEON system.

     As a result of the foregoing factors, there can be no assurance that the
Company will generate significant revenues, achieve or sustain profitability or
generate positive cash flow from operating activities in the future. If the
Company cannot generate significant revenues, achieve and sustain profitability
or generate positive cash flow from operating activities in the future, it will
not be able to make principal and interest payments with respect to its
indebtedness (including the Notes) or meet its other debt service or working
capital requirements, and the securities offered hereby would have little or no
value.


Risks Associated with Completing the NEON System

     The Company's ability to achieve its strategic objectives will depend in
large part upon the successful, timely and cost-effective completion of the
NEON system. Factors that could affect such completion include, among other
things, (i) obtaining adequate ROWs on acceptable terms in and between major
cities in the Northeast, (ii) obtaining required governmental permits and
certifications where necessary and (iii) delays or disruptions resulting from
physical damage, power loss, defective equipment or the failure of third-party
suppliers or contractors to meet their obligations in a timely and
cost-effective manner. No assurance can be given that the Company will be able
to complete the NEON system or achieve completion on time or within the
anticipated budget.

     In order to complete the NEON system, the Company must obtain additional
rights-of-way and other permits from third parties, including electric
utilities and transit authorities to install fiber optic cables. In particular,
the


                                       13
<PAGE>

Company has not yet obtained the necessary ROWs to or within the planned
Boston, Massachusetts segment of the NEON system, the planned segment of the
system from White Plains, New York to Manhattan or the planned segment in and
around Rhode Island. Nor has the Company yet obtained the necessary ROWs to
expand the NEON system to encompass the planned New York local loop or the
extensions therefrom into New Jersey. There can be no assurance that the
Company will be successful in obtaining such agreements on acceptable terms.
The Company is currently in negotiations with several electric utilities to
install extensions to the NEON system and with certain transit authorities to
install redundant NEON system paths. If the Company is unable to reach
agreement with the foregoing parties on terms acceptable to the Company, then
such failure may prevent the completion of the NEON system as currently planned
by the Company, and such a result would have a material adverse effect on the
Company's business, financial condition and results of operation. In addition
if CMP or NU or any other entity with whom the Company has an agreement seeks
bankruptcy or other protection from its creditors, the Company's ability to
exercise route extensions or other rights under its agreement with such entity
may be adversly affected.


Risks Associated with Implementing the Company's Strategy

     The Company's ability to implement its business strategy is dependent upon
the Company's ability to secure a market for its leased fiber optic capacity
and obtain service contracts with communications carriers.

     The Company's ability to attract and retain customers is crucial to the
Company's success. Many of the Company's targeted customers are companies that
may also be the Company's potential competitors. If the Company's services are
not satisfactory or cost competitive, the Company's potential customers may
elect to develop their own competing systems in the Company's markets. The
Company has incurred and will continue to incur significant operating expenses,
has made and will continue to make significant capital investments and has
entered into equipment supply contracts and service arrangements, in each case
based upon certain expectations as to the anticipated customer demand for the
Company's services in its markets. Accordingly, the failure of the Company to
attract and retain sufficient communications carriers for its services would
materially and adversely affect the Company's business, financial condition and
results of operations.

     The Company's business strategy assumes that its current and future
revenues will come from its services to communications carriers, which are
limited in number. Therefore, dissatisfaction with the Company's services by a
relatively few number of communications carriers could have a material adverse
effect on the Company's business, financial condition and results of
operations. For the year ended December 31, 1997, the Company's two largest
customers accounted for 69% and 10% of total revenues, respectively, and for
the three months ended March 31, 1998, the Company's two largest customers
accounted for 76% and 10% of total revenues, respectively. The Company is aware
that certain IXCs are constructing or considering constructing new networks, or
buying companies with local networks, which could reduce their need for the
Company's services. See "--Competition." Accordingly, there can be no assurance
that any of the Company's customers or potential customers will use or increase
their use of the Company's services, which would have a material adverse effect
on the Company's business, financial condition and results of operations.

     Implementation of the Company's business strategy also will require
substantial growth in the Company's management base, systems and other
operations and may be affected by factors such as: (i) the availability of
financing and regulatory approvals; (ii) the existence of strategic alliances
or relationships; (iii) technological, regulatory or other developments in the
Company's business; (iv) changes in the competitive climate in which the
Company operates; and (v) the emergence of future opportunities.


Risks Associated with Contractual Rights-of-Way

     The construction and operation of the NEON system by the Company is
dependent upon indefeasible rights of use ("IRUs") granted to the Company in
ROWs and in fiber optic filaments. IRUs, which are created by contract, have
been used extensively in the telecommunications industry and convey to the
holder greater ownership attributes than do leases. Although IRUs confer upon
the holder certain indicia of ownership, legal title and the right to control
the ROW or the fiber optic filaments, as the case may be, remain in the hands
of the grantor. Therefore, while IRUs might be construed as conferring a
significant equitable ownership right in the ROW or the fiber optic filaments,
as the case may be, the legal status of IRUs remains uncertain, and there can
be no assurance that a trustee in bankruptcy would not void an IRU in the event
of the bankruptcy of the grantor of such IRU. In addition, the IRUs granted by
CMP and the NU companies are subject to pre-existing, system-wide mortgages
used to secure utility


                                       14
<PAGE>

bonds issued by those companies. The Company has sought acknowledgments from
the NU companies' indenture trustees that the Company's rights under the NU
Agreements would be recognized in the event of the foreclosure of the related
mortgage. Such agreements have been obtained from the indenture trustees for
The Connecticut Light and Power Company and Western Massachusetts Electric
Company, and negotiations are ongoing with the indenture trustee of Public
Service Company of New Hampshire ("PSNH"). If such an agreement is not obtained
from PSNH's indenture trustee, a default by PSNH under its mortgage that
resulted in the foreclosure of the mortgage could result in the Company losing
its rights under the NU Agreements in the State of New Hampshire. The Company
has not sought such acknowledgments from CMP's indenture trustees and a default
by CMP under its mortgage that resulted in the foreclosure of the mortgage
could result in the Company losing its rights under the CMP Agreement.

     The Company's IRUs are derivative of the grantor's interest in the real
property on which the NEON system is located. To the extent that the grantor
only has a limited easement in such property, the IRUs granted to the Company
may be alleged to be insufficient for the Company's uses. Although the Company
believes that its existing IRUs are sufficient for the Company's purposes,
there may be disputes from time to time over the scope of the related
easements. If any such dispute cannot be satisfactorily resolved, including by
the Company obtaining its own easement, the Company might be required to
reroute portions of the NEON system, which would result in additional costs and
possible delays in constructing and operating the NEON system.

     The NU Agreements and the CMP Agreement contain provisions which
acknowledge the right of NU and CMP, respectively, to make the provision of
electrical services to their own customers their top priority; NU and CMP are
required only to exercise "reasonable care" with respect to the Company's
facilities and are otherwise free to take whatever actions they deem
appropriate with respect to ensuring or restoring service to their electricity
customers, any of which actions could impair the operation of the NEON system.
In addition, the Company's construction efforts are constrained by the ability
of NU and CMP to shut down certain segments of their transmission facilities in
order to permit construction crews to work safely. The Company has experienced
construction delays in the past as a result of the ability of NU to shut down
segments of its facilities scheduled for fiber installation and may experience
such delays in the future.

     Some of the agreements that the Company enters into to construct and
operate the NEON system may be short-term or revocable at will, and there can
be no assurance that the Company will have continued access to existing
rights-of-way after their expiration or termination. If any of these agreements
were terminated as a result of among other things a default by the Company of
its obligations thereunder including failure to maintain any necessary
governmental approvals or could not be renewed on commercially reasonable terms
and the Company lost its rights in the fiber optic cable or abandoned portions
of its NEON system, such actions would impair the operation of the NEON system.
See "Business--Right-of-Way Agreements."


Competition

     The telecommunications industry is highly competitive. The Company faces
substantial competition from ILECs, which currently dominate their local
telecommunications markets, and CLECs, most of which have greater financial and
other resources than the Company. In addition to ILECs and CLECs, potential
competitors capable of offering services similar to those offered by the
Company include IXCs, other facilities-based communications service providers,
cable television companies, electric utilities, microwave carriers, satellite
carriers, wireless telephone system operators and large end-users with private
networks. There can be no assurance that such entities will not compete with
the Company or that such competition would not have a material adverse effect
on the Company's business, financial condition and results of operations. See
"Business--Competition."

     The Company is currently aware of communications carriers that own or
lease fiber optic networks in New England (such as AT&T, MCI, Sprint, Bell
Atlantic, Southern New England Telecommunications Corporation, WorldCom,
Teleport and MFS Communications Company Inc.) and of other carriers (such as
IXC Communications, Qwest Communications International Inc., Metromedia Fiber
Network Inc., Level 3 and RCN Inc.) who are planning to own or lease additional
networks which, if constructed, could employ advanced technology comparable to
that of the NEON system.

     NU and CMP each own or have the irrevocable right to use certain fibers in
the cable that includes the NEON system, which permit NU and CMP to compete
directly with the Company in the future if they are not using these fibers for
their own corporate requirements. See "Business--Right-of-Way Agreements." In
addition the


                                       15
<PAGE>

Company's ROWs are nonexclusive in that other service providers could install
competing networks using the same ROWs.

     In the future, the Company may be subject to more intense competition due
to the development of new technologies, an increased supply of domestic and
international transmission capacity, the consolidation in the industry among
local and long distance service providers and the effects of deregulation
resulting from the Telecommunications Act of 1996. The introduction of new
products or emergence of new technologies may reduce the cost or increase the
supply of certain services similar to those provided by the Company. The
Company cannot predict which of many possible future product and service
offerings will be crucial to maintain its competitive position or what
expenditures will be required to develop profitably and provide such products
and services.


Regulatory Risks

     Regulation of the telecommunications industry is changing rapidly.
Existing and future federal, state and local governmental regulations will
greatly influence the viability of the Company. Consequently, undesirable
regulatory changes could adversely affect the Company's business, financial
conditions and results of operations. For instance, while the Company does not
believe that its fiber offerings, as proposed, are subject to common carrier
regulation by the Federal Communications Commission ("FCC") or under the common
carrier provisions of the Communications Act of 1934, as amended (the
"Communications Act"), except with respect to its subsidiaries in New York and
Connecticut, the Company cannot predict the future regulatory status of its
business. In addition, ILECs and IXCs are subject to various federal
telecommunications laws. Accordingly, changes in federal telecommunications law
may affect the Company's business by virtue of the inter-relationships that
exist among the Company and many of these regulated telecommunications
entities. It is difficult for the Company to forecast at this time how these
changes will affect the Company in light of the complex interrelationships that
exist in the industry and the different levels of regulation. For a more
detailed discussion of the regulatory environment in which the Company conducts
its business, see "Business--Regulation".

     The regulatory environment also varies substantially from state to state.
At present, the Company does not anticipate that the regulatory requirements to
which it will be subject in New England and New York will have any material
adverse effect on its operations, although the Company may incur certain costs
to comply with regulatory requirements such as the filing of tariffs,
submission of periodic financial and operational reports to regulators, and
payment of regulatory fees and assessments in Connecticut and New York. In some
jurisdictions, the Company's pricing flexibility for intrastate services may be
limited because of regulation, although the Company's direct competitors will
be subject to similar restrictions.


Rapid Technological Changes

     The telecommunications industry is subject to rapid and significant
changes in technology. For instance, recent technological advances permit
substantial increases in transmission capacity of both new and existing fiber,
and the introduction of new products or emergence of new technologies may
reduce the cost or increase the supply of certain services similar to those
provided by the Company. While the Company believes that, for the foreseeable
future, technological changes will neither materially affect the continued use
of fiber optic cable nor materially hinder the Company's ability to acquire
necessary technologies, the effect of technological changes on the Company's
operations cannot be predicted and could have a material adverse effect on the
Company's business, financial condition and results of operations.


Dependence on Limited Source Suppliers

     The Company is dependent upon third-party suppliers for a number of
components and parts used in the NEON system. In particular, the Company is
dependent primarily on Lucent Technologies, Inc. ("Lucent") for its supply of
fiber optic glass. The Company's arrangements with Lucent have provided it with
a supply of fiber optic glass at a price and on terms acceptable to the
Company. The Company believes that there are alternative suppliers or
alternative components for all of the components contained in the NEON system.
However, any delay or extended interruption in the supply of any of the key
components currently obtained from a single or limited source, changes in the
pricing arrangements with its suppliers or delay in transitioning a replacement
supplier's product into the NEON system could disrupt the Company's operations
and have a material adverse effect on the Company's business, financial
condition and results of operations.


                                       16
<PAGE>

Pricing Pressures and Industry Capacity

     Although the Company believes that, in the last several years, increasing
demand for fiber optic transmission capacity has resulted in a shortage of
capacity and slowed a decline in prices, the Company anticipates that prices
for its services to carriers specifically, and interstate services in general,
will continue to decline over the next several years due primarily to (i) price
competition as various network providers continue to install networks that
compete with the NEON system, (ii) technological advances that permit
substantial increases in the transmission capacity of both new and existing
fiber and (iii) strategic alliances or similar transactions, such as long
distance capacity purchasing alliances among certain ILECs, that increase
customer purchasing power. Such price decreases without offsetting decreases in
the Company's cost of services or increases in demand for the Company's
services, could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."


Limited Nature of Company's Services

     The Company is a facilities-based provider of technologically advanced,
high-bandwidth, fiber optic communications infrastructure, and it is not
currently engaged in the transmission of voice, data or video services and does
not provide switched voice and data services. Accordingly, at the present time,
the Company, unlike other telecommunications companies, receives no revenues
from providing such services, and instead derives and expects to continue to
derive substantially all of its revenues from the leasing of fiber optic
capacity to its customers, many of whom transmit voice, data or video
information or provide switched voice and data services. The limited nature of
the Company's current services could limit potential revenues and result in the
Company having lower revenues than competitors which provide a wider array of
services. See "Business--Customers" and "--Competition."


Dependence Upon Network Infrastructure; Risk of System Failure

     The Company's success in marketing its services to its customers requires
that the Company provide superior reliability, capacity and security via its
network. The Company's network and networks upon which it depends are subject
to physical damage, power loss, capacity limitations, software defects,
breaches of security and other disruptions that may cause interruptions in
service or reduced capacity for customers, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company's agreements with its customers typically provide for
the payment of damages in the event of a disruption in service, which damages
could be substantial and could have a material adverse effect on the Company's
business, financial condition and results of operations.


Dependence on Key Personnel

     The Company's future performance will depend to a significant extent upon
the efforts and abilities of its senior executives. The loss of service of one
or more of these persons could have an adverse effect on the Company's
business. There can be no assurance that the Company will be able to attract
and retain qualified executives to achieve its business objectives. See
"Management."


High Leverage; Ability to Service Indebtedness

     Upon completion of the Offerings, the Company will be highly leveraged. As
of March 31, 1998, on a pro forma basis after giving effect to the Offerings,
the Company and its subsidiaries would have had outstanding $    million of
indebtedness and the Company's ratio of total debt to total capitalization
would have been   %. [D]Although the Indenture will contain certain limitations
on the ability of the Company and its subsidiaries to incur additional
Indebtedness (as defined), under certain circumstances such additional
Indebtedness could be substantial and such limitations generally do not
restrict the Company and its subsidiaries from incurring liabilities that do
not constitute Indebtedness.

     The Company's high degree of leverage could have adverse consequences to
the holders of the Company's securities. Such consequences may include, among
other things: (i) commencing on       2004, a substantial portion of the
Company's cash flow will be dedicated to the payment of the Company's interest
expense with respect to the Notes and such cash flow may be insufficient to
meet its payment obligations on the Notes in addition to paying other
obligations of the Company as they become due; (ii) the Company's ability to
obtain any necessary


                                       17
<PAGE>

financing in the future for completion of the NEON system or other purposes may
be impaired; (iii) certain of the future borrowings by the Company may be at
variable rates of interest that could cause the Company to be vulnerable to
increases in interest rates; (iv) the Company may be more leveraged than its
competitors, which may place the Company at a competitive disadvantage; and (v)
the Company may be vulnerable to a downturn in its business or the economy
generally or to delays in or increases in the cost of constructing the NEON
system.

     For the year ended December 31, 1997 and the three months ended March 31,
1998, the Company's pro forma fixed charges would have exceeded the Company's
earnings by $         and $        , respectively. The Company's ability to pay
principal and interest on the Notes and any additional indebtedness it may
incur after the Offerings will depend upon its ability to complete and operate
the NEON system and its future operating performance, which will be affected by
prevailing economic conditions and financial, business and other factors, many
of which are beyond its control. There can be no assurance that the NEON system
will be completed on time or on budget or that the Company will be able to
generate sufficient cash flow to pay its indebtedness and its other obligations
as they become due. If the Company is unable to service its indebtedness, the
Company will be forced to take actions such as reducing or delaying
acquisitions or capital expenditures, selling assets, restructuring or
refinancing its indebtedness or seeking additional equity capital. There is no
assurance that any of these remedies could be effected on satisfactory terms,
if at all, including, whether, and on what terms, the Company could refinance
its indebtedness or raise equity capital.

     The Indenture imposes and will impose significant operating and financial
restrictions on the Company and its present and future subsidiaries. These
restrictions affect, and in certain cases significantly limit or prohibit,
among other things, the ability of the Company and its subsidiaries to incur
certain indebtedness, pay dividends and make certain other restricted payments,
create liens, issue and sell capital stock of subsidiaries, guarantee certain
indebtedness, sell assets, or consolidate, merge or transfer all or
substantially all of their assets. There can be no assurance that such
covenants will not adversely affect the Company's ability to finance its future
operations or capital needs or to engage in attractive business opportunities.


[D] Priority of Secured Debt

     The Notes will be unsecured and will be effectively subordinated to any
future secured indebtedness of the Company to the extent of the value of the
assets securing such indebtedness. The Indenture will permit the Company or its
subsidiaries to incur additional secured indebtedness, including purchase money
indebtedness. See "Description of the Notes." In the event of a bankruptcy,
liquidation, dissolution, restructuring or similar proceeding with respect to
the Company, such assets will be available to satisfy obligations of any such
secured debt before any payment can be made on the Notes. In addition, to the
extent such assets would not satisfy in full any such secured indebtedness, the
holders of such indebtedness will have a claim for any shortfall that is pari
passu (or effectively senior if the indebtedness were issued by the
subsidiaries) with the Notes. Accordingly, there may only be a limited amount
of assets available to satisfy any claims of the holders of the Notes upon an
acceleration of the Notes.


Concentration of Stock Ownership; Potential Conflicts of Interest

     After consummation of the Offerings, MaineCom Services ("MaineCom"), an
affiliate of Central Maine Power Company ("CMP"), and Mode 1 Communications,
Inc. ("Mode 1"), an affiliate of Northeast Utilities ("NU"), will beneficially
own or control, in the aggregate, more than 50% of the outstanding Common
Stock. As a result of their stock ownership, these stockholders acting together
will be able to continue to elect the members of the Board of Directors and
decide all matters requiring stockholder approval. See [E]"Principal and
Selling Stockholders" [D]"Principal Stockholders."

     The Company has entered into various agreements with CMP and NU, including
its existing ROW agreement and agreements for the engineering and construction
of the NEON system. Certain conflicts may arise between the interests of CMP
and NU and other securityholders of the Company. Pursuant to such agreements,
CMP and NU may have monetary claims from time to time against the Company. See
"Business--Right-of-Way Agreements" and "Certain Transactions."

     CMP and NU have entered into an agreement dated May   , 1998, whereby each
such party agrees that, following the completion of the Offerings, it will not
permit or cause the Company to (i) merge or consolidate, liquidate or dissolve,
change its form of organization or sell, lease, exchange or transfer all or
substantially all of


                                       18
<PAGE>

its assets; or (ii) seek bankruptcy protection or certain other protection from
creditors, unless both parties agree. After the closing of the Offerings, this
agreement will remain in effect for so long as (a) NU owns at least 10% of the
outstanding Common Stock of the Company, fully diluted and (b) the aggregate
Common Stock of the Company owned by NU and CMP is at least 331/3% of the
outstanding Common Stock of the Company, fully diluted. The Company expects
that each of CMP and NU will be major creditors of the Company under their
existing ROW agreements. See "Business--Right-of-Way Agreements" and
"Description of Capital Stock--Shareholder Agreement."


[E] No Prior Public Market; Possible Volatility of Stock Price

     Prior to the Equity Offering, there has been no public market for the
Common Stock. The initial public offering price of the Common Stock will be
determined by negotiations between the Company and the Representatives of the
Underwriters and may not be indicative of the market price for the Common Stock
in the future. See "Underwriting" for a discussion of the factors to be
considered in determining the initial public offering price. There can be no
assurance that an active trading market for the Common Stock will develop or be
sustained after the Equity Offering. If a trading market develops, the market
price of the Common Stock may fluctuate widely as a result of various factors,
such as period-to-period fluctuations in the Company's operating results, sales
of Common Stock by principal stockholders, developments in the industry,
competitive factors, regulatory developments, economic and other external
factors, general market conditions and market conditions affecting stocks of
telecommunications companies in particular. The stock market in general, and
the stocks of telecommunications companies in particular, have in the past
experienced extreme volatility in trading prices and volumes that has often
been unrelated to operating performance. Such market volatility may have a
significant adverse affect on the market price and marketability of the Common
Stock. See "Underwriting."


[E] Absence of Dividends

     The Company anticipates that all of its earnings in the foreseeable future
will be retained to finance the continued growth and expansion of its business
and has no current intention to pay cash dividends on its Common Stock. See
"Dividend Policy."


[E] Shares Eligible for Future Sale

     Upon consummation of the Equity Offering,    shares of Common Stock will
be outstanding (shares if the Underwriters' over-allotment option is exercised
in full), of which    will be freely tradeable (shares if the Underwriters'
over-allotment option is exercised in full). Of the    remaining shares, shares
are held by MaineCom and Mode 1 who, together with the Company and its officers
and directors, have entered into an agreement not to sell, contract to sell, or
otherwise dispose of, any shares of Common Stock without the consent of Credit
Suisse First Boston Corporation for a period of 180 days after the date of this
Prospectus (the "Lock-Up Agreement"). Upon expiration of such agreements, such
shares will be eligible for sale in the public markets in accordance with Rule
144 ("Rule 144") promulgated under the Securities Act of 1933, as amended (the
"Securities Act"). At April 30, 1998, there were outstanding stock options to
purchase a total of       shares of Common Stock, of which options for
shares will be exercisable upon consummation of the Equity Offering. The shares
issued upon exercise of these options will be potentially eligible for public
sale 90 days after the date of this Prospectus pursuant to Rule 701 under the
Securities Act. All holders of such options, however, have signed Lock-Up
Agreements. Except as limited by the Lock-Up Agreements and by Rule 144 volume
limitations applicable to affiliates, shares issued upon the exercise of stock
options generally are available for sale in the open market. Future sales of
significant amounts of Common Stock in the public market after the Equity
Offering, could adversely affect the prevailing market price of the Common
Stock. See "Shares Eligible for Future Sale."


[E] Immediate and Substantial Dilution

     Investors purchasing Common Stock in the Equity Offering will experience
immediate and substantial dilution in the net tangible book value of their
shares. Assuming an initial public offering price of $     per share
(representing the midpoint of the estimated price range), dilution to new
investors would be $     per share. Additional dilution will occur upon
exercise of outstanding stock options. If the Company seeks additional capital
in the future, the issuance of shares or securities convertible into shares of
Common Stock to obtain such capital may lead to further dilution. See
"Dilution."


                                       19
<PAGE>

[E] Antitakeover Effect of Certain Charter Provisions.

     The Board of Directors has the authority to issue up to 2,000,000 shares
of Preferred Stock and to determine the price, rights, preferences, privileges
and restrictions, including voting rights, of those shares without any further
vote or action by the stockholders. The rights of the holders of Common Stock
may be subject to, and may be adversely affected by, the rights of the holders
of any Preferred Stock that may be issued in the future. The issuance of
Preferred Stock may have the effect of delaying, deferring or preventing a
change of control of the Company without further action by the stockholders and
may adversely affect the voting and other rights of the holders of Common
Stock, which could have an adverse impact on the market price of the Common
Stock. The Company has no present plans to issue shares of Preferred Stock.
Further, certain provisions of the Company's charter documents, including
provisions eliminating the ability of stockholders to take action by written
consent and limiting the ability of stockholders to raise matters at a meeting
of stockholders without giving advance notice, may have the effect of delaying
or preventing changes in control or management of the Company, which could have
an adverse effect on the market price of the Company's Common Stock. The
Company is subject to the anti-takeover provision of Section 203 of the
Delaware General Corporation Law, which will prohibit the Company from engaging
in a "business combination" with an "interested stockholder" for a period of
three years after the date of the transaction in which the person became an
interested stockholder, unless the business combination is approved in a
prescribed manner. The application of Section 203 also could have the effect of
delaying or preventing a change of control of the Company. See "Description of
Capital Stock."


[D] Consequences of Original Issue Discount on Notes

     The Notes will be issued at a substantial discount from their principal
amount. Consequently, purchasers of the Notes generally will be required to
include amounts in gross income for federal tax purposes in advance of receipt
of the cash payments to which the income is attributable, and generally no cash
payments of interest will be made until      , 2004. See "Certain United States
Federal Income Tax Consequences" for a more detailed discussion of the federal
income tax consequences to purchasers of the Notes.

     If a bankruptcy proceeding is commenced by or against the Company under
the United States Bankruptcy Code after the issuance of the Notes, the claim of
a holder of Notes may be limited to an amount equal to the sum of (i) the
initial offering price for the Notes and (ii) that portion of the original
issue discount that is not deemed to constitute "unmatured interest" for
purposes of the United States Bankruptcy Code. Any original issue discount that
was not amortized as of the commencement of any such bankruptcy proceeding
would constitute "unmatured interest."


[D] Purchase of Notes Upon Change of Control

     Upon a Change of Control, the Company must offer to purchase all
outstanding Notes at 101% of the Accreted Amount thereof, plus accrued and
unpaid interest to the date of purchase. The source of funds for any such
purchase would be the Company's available cash or cash generated from other
sources. However, there can be no assurance that sufficient funds would be
available at the time of any Change of Control to make any required purchases
of Notes tendered. See "Description of the Notes--Change of Control."


[D] Absence of Trading Market for the Notes

     The Notes constitute a new issue of securities, have no established
trading market and may not be widely held. Although the Underwriters have
informed the Company that they currently intend to make a market in the Notes
as permitted by applicable laws and regulations, they are not obligated to do
so and may discontinue market making at any time without notice. The Company
does not intend to list the Notes on any national securities exchange or to
seek the admission thereof to trading in The Nasdaq Stock Market, Inc., and
there can be no assurance as to the development of any market or the liquidity
of any market that may develop for the Notes. If such a market does develop,
the price of the Notes may fluctuate and liquidity may be limited. If such a
market does not develop, purchasers may be unable to resell the Notes for an
extended period of time, if at all.

     Historically, the market for non-investment grade debt has been subject to
disruptions that has caused substantial volatility in the prices of such
securities. There can be no assurance that the market for the Notes will not be
subject to similar disruptions. Any such disruptions may have an adverse effect
on holders of the Notes.

                              [D] EQUITY OFFERING

     Concurrently with the Debt Offering, the Company and certain selling
stockholders of the Company (the "Selling Stockholders") are offering
shares of Common Stock to the public in the Equity Offering. In addition, as
part of the Equity Offering the Company and the Selling Stockholders have
granted the underwriters thereof an option to purchase up to       additional
shares of Common Stock to cover over-allotments, if any. The closing of the
Debt Offering is conditioned upon the closing of the Equity Offering, and the
closing of the Equity Offering is conditioned upon the closing of the Debt
Offering.


                               [E] DEBT OFFERING

     Concurrently with the Equity Offering, the Company is offering its   %
Senior Discount Notes Due 2008 to the public in the Debt Offering for gross
proceeds of $        million. The indenture under which the Notes will be
issued will contain certain covenants that, among other things, will limit (i)
the incurrence of additional Indebtedness by the Company and its Restricted
Subsidiaries (as defined), (ii) the payment of dividends and other restricted
payments by the Company and its Restricted Subsidiaries, (iii) the creation of
restrictions on distributions from Restricted Subsidiaries, (iv) asset sales,
(v) transactions with affiliates, (vi) sales or issuances of Restricted
Subsidiary capital stock, (vii) the incurrence of liens and the entering into
of sale/leaseback transactions and (viii) mergers and consolidations. The
closing of the Equity Offering is conditioned upon the closing of the Debt
Offering, and the closing of the Debt Offering is conditioned upon the closing
of the Equity Offering. See "Description of Certain Indebtedness."

<PAGE>

                                USE OF PROCEEDS

     [E] The net proceeds to the Company from the Equity Offering are estimated
to be approximately $     million ($     million if the Underwriters'
over-allotment option is exercised in full), assuming an initial public
offering price of $      per share, the midpoint of the estimated price range,
and after deducting the estimated underwriting discount and offering expenses.
The Company will not receive any of the proceeds from the sale of shares of
Common Stock sold by the Selling Stockholders in the Equity Offering. The net
proceeds to the Company from the Debt Offering are estimated to be
approximately $     million, after deducting the estimated underwriting
discount and offering expenses. Pending the foregoing uses, the net proceeds of
the Offerings will be invested in short-term, investment-grade securities.

     [D] The net proceeds to the Company from the Debt Offering are estimated
to be approximately $     million after deducting the estimated underwriting
discount and offering expenses and the net proceeds to the Company from the
Equity Offering are estimated to be approximately $     million ($    million
if the underwriters' over-allotment option is exercised in full), assuming an
initial public offering price of $      per share and after deducting the
estimated underwriting discount and offering expenses. Pending the foregoing
uses, the net proceeds of the Offerings will be invested in short-term,
investment-grade securities.

     The Company intends to use the net proceeds of the Offerings, estimated to
be $          , for capital expenditures associated with the continued
construction and expansion of the NEON system, to repay certain indebtedness
and for working capital and general corporate purposes. Such indebtedness to be
repaid includes approximately $           of principal plus accrued interest
under the Company's Construction Loan Agreement with CMP (the "CMP Loan
Agreement") and approximately $       of principal, prepayment premium plus
accrued interest under the Company's Construction Loan Agreement with Peoples
Heritage Savings Bank (the "Peoples Loan Agreement"). Indebtedness under the
CMP Loan Agreement and the Peoples Loan Agreement bears interest at an annual
rate of LIBOR plus 3% and 9.25%, respectively, and matures in 2002 and 2007,
respectively.


                              [E] DIVIDEND POLICY

     The Company intends to retain future earnings, if any, to finance the
development and expansion of its business and, therefore, does not anticipate
paying any cash dividends on its Common Stock in the foreseeable future. The
payment of dividends is within the discretion of the Company's Board of
Directors and will be dependent upon, among other factors, the Company's
results of operations, financial condition and capital requirements,
restrictions imposed by the Company's financing arrangements and legal
requirements.

     The terms of the Notes will restrict the Company's ability to pay cash
dividends on its Common Stock. See "Description of Certain Indebtedness."

<PAGE>

                                 [E] DILUTION

     At March 31, 1998, after giving effect to the Reorganization, the Company
had a net tangible book value of approximately $10,870,000 or $     per share
of Common Stock. Net tangible book value per share represents the amount of
total tangible assets less total liabilities divided by the number of shares of
Common Stock outstanding, after giving effect to the Preferred Stock Conversion
and the Stock Split. After giving effect to the sale of shares of Common Stock
offered by the Company hereby at an assumed initial public offering price of
$     per share (the mid-point of the estimated price range) and after
deducting the estimated underwriting discount and offering expenses payable by
the Company, the pro forma net tangible book value of the Company as of March
31, 1998 would have been approximately $     or $     per share. This
represents an immediate increase in net tangible book value of $     per share
to the existing stockholders and an immediate dilution of $     per share to
new investors. The following table illustrates this per share dilution:

- ---------------------
(1) In connection with the Reorganization, the minority interests in the
    Company's subsidiaries were exchanged for Series B convertible preferred
    stock, resulting in the elimination of any minority interest and an
    increase of 3,535,637 shares of Series B convertible preferred stock, of
    which 144,172 shares arose from CMP's exercise of a warrant.

(2) In connection with the Reorganization, the par value of the Series A
    convertible preferred stock, Series B convertible preferred stock and
    common stock was reduced from $0.05 to $0.01 per share, resulting in a
    reduction in stated capital of $3,133, $38,509 and $4,557 in Series A
    convertible preferred stock, Series B convertible preferred stock and
    common stock, respectively, and a corresponding increase in additional
    paid-in-capital of $46,199.

(3) In connection with the Reorganization, the conversion rate on the Series A
    convertible preferred stock was reduced to a 1 : 1 ratio and 199,636
    additional shares of Series A convertible preferred stock were issued to
    adjust for such reduction.

(4) Excludes (i) shares of Common Stock issuable upon the exercise of stock
    options outstanding as of March 31, 1998 with an exercise price of $
    per share, (ii) an additional         shares of Common Stock reserved for
    future issuance under the Company's 1998 Stock Incentive Plan, and (iii)
            shares of Common Stock issuable upon the exercise of warrants
    outstanding as of March 31, 1998 with an exercise price of $     per
    share.

(5) The exercise of the CMP warrant ultimately resulted in an increase in
    additional paid in capital of $531,394, which represents the difference
    between the actual book value of the warrant and the new par value of
    Series B convertible preferred stock arising upon exercise of the warrant.
     

(6) In connection with the Reorganization, the Company recorded an intangible
    asset of $48,092,600 to reflect the Company's acquisition of NU's minority
    interest in subsidiaries (NECOM LLC and FiveCom LLC), in accordance with
    AICPA Accounting Interpretation 39 to APB Opinion No. 16, Business
    Combinations (AIN-39).

(2) Adjusted to give effect to the Reorganization. In connection with the
    Reorganization, the Company recorded an intangible asset of $48,092,600 to
    reflect the Company's acquisition of NU's minority interest in
    subsidiaries (NECOM LLC and FiveCom LLC), in accordance with AICPA
    Accounting Interpretation 39 to APB Opinion No. 16, Business Combinations
    (AIN-39). The intangible will be amortized over 30 years, reflecting
    assignment of value to goodwill and to the rights of ways, which have
    30-year terms. If the Reorganization had occurred as of January 1, 1997
    the pro forma impact on the Company's Statement of Operations for the year
    ended December 31, 1997 would reflect amortization of $1,603,087, a net
    loss of $(2,563,113) and a loss per share of $       . The pro forma
    impact on the Company's Statement of Operations for the quarter ended

    loss would be $         for 1997 and $        for the first quarter of
    1998 reflecting the additional interest expense from the issuance of the
    __% Senior Discount Notes.

(4) For purposes of calculating the ratio of earnings to fixed charges: (i)
    earnings consist of loss before income tax benefit, plus fixed charges,

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


     The following discussion and analysis should be read in conjunction with
the Company's Consolidated Financial Statements and the Notes thereto included
elsewhere in this Prospectus. The discussion contains certain trend analysis
and other statements of a forward-looking nature relating to future events or
the future financial performance of the Company. Prospective investors are
cautioned that such statements are only projections and that actual results or
events may differ materially. In evaluating such statements, prospective
investors should consider the risk factors identified in this Prospectus,
particularly the matters set forth under the caption "Risk Factors", which
could cause actual results to differ materially from those indicated by such
forward-looking statements.


Overview

     The Company is a facilities-based provider of technologically advanced,
high bandwidth, fiber optic transmission capacity for communications carriers
on local loop, inter-city and interstate facilities. The Company is currently
expanding its fiber optic network, the NEON system, to encompass approximately
1,000 route miles, or approximately 80,000 fiber miles, concentrated in the
northeastern United States, including New York and New England (the
"Northeast").

     The Company has already completed and currently operates fiber optic
routes from Hartford, Connecticut to Springfield, Massachusetts and from
Nashua, New Hampshire to Portland, Maine, totaling approximately 212 route
miles, or approximately 13,700 fiber miles. The Company is currently
engineering or constructing additional routes in New York, Connecticut,
Massachusetts and New Hampshire to create a continuous fiber optic link between
White Plains, New York and Portland, Maine with access into and around Boston,
Massachusetts and numerous other major cities in the Northeast. These
additional routes are expected to be substantially completed in 1998 and will
add approximately 380 route miles, or approximately 30,800 fiber miles, to the
NEON system. The Company is also planning to complete further expansion routes
in 1999 connecting New York City, Providence and other metropolitan areas to
the NEON system. The completion of routes under construction and currently
planned will enable the NEON system to connect more than 540 cities and towns
in six states and pass more than 200 points-of-presence ("POPs"), tandem
switches and central offices, which the Company believes serve over 18 million
people and over 470,000 businesses.

     The Company generates revenue through the leasing of capacity on its
network and through the provision of services, consisting principally of design
and installation work. The Company generally receives fixed monthly payments
from its customers for the leasing of capacity on its network and recognizes
revenues ratably over the term of the applicable customer agreement. Other
service revenues are recognized as services are performed.

     Prior to the Reorganization, the Company held interests in its
majority-owned or controlled subsidiaries, FiveCom LLC, FiveCom of Maine LLC
and NECOM LLC. The interests of the minority owners of these subsidiaries is
reflected on the Company's balance sheet as minority interest in consolidated
subsidiaries. As a result of the Reorganization, the minority owners became
stockholders of the Company, and the value of the stock of the Company received
by them over the tangible book value of their minority interests was reflected
as goodwill.

     Prior to the Offerings, the Company was included in CMP's consolidated
federal income tax return pursuant to the terms of a tax-sharing arrangement
entered into in 1996. The benefit from income taxes represents refundable
income taxes from CMP as a result of this tax sharing arrangement. The Company
has no net operating loss carryforwards as a result of this tax sharing
arrangement.


Results Of Operations

     The Company did not generate significant revenues until the last half of
1997. Revenues through the second quarter of 1997 consisted primarily of
service fees from one customer. The Company began recognizing revenues under
recurring lease arrangements in the third quarter of 1997.


Three Months Ended March 31, 1998 Compared to the Three Months Ended March 31,
1997

     Revenues for the first quarter of 1998 were $151,363, compared to no
revenue in the first quarter of 1997. Revenues in 1998 were generated by
recurring lease services to customers, which commenced during the second half
of 1997.


                                       28
<PAGE>

     Total cost of sales for the first quarter of 1998 were $247,386, an
increase of 128% over the $108,358 recorded in the first quarter of 1997. The
increase was associated with right-of-way fees and property taxes incurred in
connection with the expansion of the NEON system.

     Selling, general and administrative expenses increased to $225,122 in
first quarter of 1998 from $207,383 in the first quarter of 1997, a 9%
increase. This increase resulted primarily from higher legal fees.

     Depreciation and amortization expense was $302,013 in the first quarter of
1998 as compared to $29,879 in the first quarter of 1997. The increase resulted
from higher depreciation expenses, resulting from portions of the NEON system
being placed into service at the end of the second quarter of 1997.

     Interest income decreased in the first quarter of 1998 to $30,322 compared
to $56,638 in the first quarter of 1997. The decline was due primarily to a
decrease in cash balances as cash was used to fund construction of the NEON
system.

     Interest expense (including the amortization of financing costs) increased
in the first quarter of 1998 to $91,816 from no interest expense in the first
quarter of 1997. The increase resulted from a reduction in the amount of
interest capitalized as the NEON system was placed into service.

     Minority interest increased in the first quarter of 1998 to $314,498 from
$186,478 in the first quarter of 1997. The increase resulted in a rise in the
proportionate share of the net losses of subsidiaries.

     Benefit from income taxes increased in the first quarter of 1998 to
$77,000 from $33,000 in the first quarter of 1997. The benefit related to
refundable income taxes in 1997 resulting from the Company's tax sharing
arrangement with CMP.

     A net loss of $293,154 was recorded in the first quarter of 1998 versus a
net loss of $69,504 in the first quarter of 1997. The increase in net loss is
primarily attributable to the factors discussed above.


Year Ended December 31, 1997 Compared to the Year Ended December 31, 1996

     During the years ended December 31, 1997 and 1996, the Company was
continuing in its development stage and did not generate significant revenues
until the last half of 1997, when customers began using the NEON system.

     Revenues for 1997 were $394,704 as compared to 1996 revenues of $13,773.
The revenue increase was generated primarily from services to customers during
the last half of 1997 as the NEON system was placed in service and contracts
with carriers commenced.

     Cost of sales for 1997 were $1,137,943 as compared to $260,619 in 1996.
The increase resulted primarily from right-of-way fees and property taxes
incurred in connection with the expansion of the NEON system.

     Selling, general and administrative expenses increased to $1,002,232 in
1997 from $900,808 in 1996, an 11% increase. This increase resulted primarily
from increased professional fees and salaries and benefits caused by increased
business activities and growth within the Company.

     Depreciation and amortization expense was $552,862 in 1997 as compared to
$24,168 in 1996. The increase resulted from the recognition of depreciation
expense resulting from portions of the NEON system being placed into service at
the end of the second quarter of 1997.

     Interest income of $138,918 was recorded in 1997 as compared to $201,473
in 1996. The decline was due primarily to a decrease in cash balances as cash
was used to fund construction of the NEON system.

     Interest expense (including the amortization of financing costs) increased
in 1997 to $141,811 from $75,635 in 1996. The increase reflects additional debt
incurred in 1997 to finance construction of the NEON system and to fund
operations of the Company.

     Minority interest increased in 1997 to $1,080,200 from $353,222 in 1996.
The increase resulted from an increase in the proportionate share of net losses
of subsidiaries.

     Provision (benefit) for income taxes decreased in 1997 to $(261,000) from
$16,000 in 1996. The decrease relates to the fact that the Company had
refundable income taxes in 1997 as a result of its tax sharing arrangement with
CMP.


                                       29
<PAGE>

     A net loss of $960,026 was recorded in 1997 compared to a net loss of
$708,762 in 1996. The increase in net loss is primarily attributable to the
factors discussed above.


Year Ended December 31, 1996 Compared to the Year Ended December 31, 1995

     Revenues decreased to $13,733 for the year ended December 31, 1996 from
$42,598 for the year ended December 31, 1995. The decrease resulted from the
reduced need for services from the Company's sole customer. Revenue was
generated primarily from service fees to one customer.

     Cost of sales for 1996 were $260,619, an increase of 150% versus $104,223
in 1995. The increase was associated with an increase in right-of-way fees.

     Selling, general and administrative expenses increased to $900,808 in 1996
from $358,761 in 1995, a 151% increase. The increase resulted primarily from
higher professional fees, increased start-up activities within the Company and
increased staffing to accommodate the Company's anticipated growth.

     Depreciation and amortization amounted to $24,168 for the year ended
December 31, 1996 compared to $24,175 for the year ended December 31, 1995.

     Interest income of $201,473 was recorded in 1996 as compared to no
interest income in 1996. The interest income increased in 1996 due primarily to
an increase in cash balances as a result of the timing of cash requirements to
fund construction of the fiber optic network compared to borrowings.

     Interest expense (including the amortization of financing costs) increased
to $75,635 during 1996 from $42,401 during 1995. This increase was a result of
additional debt incurred in 1996 to finance construction of the NEON system and
to fund the operations of the Company.

     Minority interest increased in 1996 to $353,222 from no minority interest
in 1995. Minority interest reflects the portion of the net loss related to the
minority interest investment in the Company's subsidiaries in 1996.

     A net loss of $708,762 was recorded in 1996 compared to a net loss of
$486,962 in 1995, representing an increase of $221,800. The increase in net
loss is attributable to the factors discussed above.


Liquidity and Capital Resources

     The Company has funded the construction of the NEON system and operations
primarily from equity investments from CMP and NU, and borrowings under a $30
million construction loan agreement with CMP, a $1.6 million construction loan
from Peoples Heritage Bank and $1.5 million of lease financing from Applied
Telecommunications Technologies, Inc.

     Net cash generated from (used in) operating activities was $657,881 for
the three months ended March 31, 1998, $(553,427) for the year ended December
31, 1997, $37,460 for the year ended December 31, 1996 and $(413,196) for the
year ended December 31, 1995. Net cash generated for the three months ended
March 31, 1998 was due primarily to a payment advanced by a customer and
increased vendor payables. Net cash used in operating activities during 1997
resulted primarily from an increase in restricted cash. Net cash generated by
operating activities during 1996 was primarily from an increase in vendor
payables offset by net operating losses. Net cash used in operating activities
in 1995 resulted primarily from increases in prepayment and net operating
losses.

     Cash flow from financing activities was $1,429,174 in the three months
ended March 31, 1998, $4,868,220 in the year ended December 31, 1997,
$14,926,603 in the year ended December 31, 1996 and $1,099,870 in the year
ended December 31, 1995. In the three months ended March 31, 1998, cash flow
from financing activities was generated by borrowings of $1,875,000 under
long-term construction loan agreements. In 1997, cash flow from financing
activities was generated by proceeds from long term construction loan
agreements and proceeds from equity investments, of $3,700,000 and $2,550,104,
respectively. In 1996, cash flow from financing activities was generated by the
sale of convertible preferred stock to CMP amounting to $10.0 million and the
purchase of membership interests by Northeast Utilities amounting to
$6,665,776. Cash flow from financing activities during 1995 was generated from
lease financing of $1,147,766 from Applied Telecommunications Technologies,
Inc.

     Upon completion of the Offerings, the Company expects to repay all
remaining outstanding principal and interest under the $30 million construction
loan agreement with CMP and the $1.6 million construction loan from


                                       30
<PAGE>

Peoples Heritage Bank. Upon the repayment of the loan from Peoples Heritage
Bank, the Company will also be required to pay approximately $115,000 to CMP,
representing accrued right-of-way fees that were deferred while such loan was
outstanding.

     Cash flow used in investing activities totaled $1,953,253, $8,081,266,
$10,020,000 and $776,272 in the periods ended March 31, 1998, December 31,
1997, December 31, 1996 and December 31, 1995, respectively. Cash requirements
in all the years consisted primarily of the cost of construction to build the
NEON system.

     The Company anticipates that it will continue to experience negative cash
flow as it expands the NEON system, constructs additional networks and markets
its services to an expanding customer base. The Company anticipates that its
capital expenditures will be approximately $65 million in 1998, relating to the
build-out of its fiber optic network. Cash provided by operations will not be
sufficient to fund the expansion and development of the network as currently
planned and as a result the Company intends to use cash on hand and the net
proceeds of the Offerings to fund this expansion and development. Management
believes that the net proceeds of the Offerings will be sufficient to fund the
substantial completion of the NEON system as currently planned and its other
working capital needs. The expectations of required future capital expenditures
are based on the Company's current estimates. There can be no assurance that
actual expenditures will not significantly exceed current estimates or that the
Company will not accelerate its capital expenditures program.

     The Company has completed an assessment of its exposure to the "Year 2000"
computer problem. Based on this assessment, the Company believes that no
critical software systems of the Company will be impacted by this situation.
Systems currently used by the Company are already "Year 2000" compliant.
Although the Company believes that it is taking appropriate precautions against
disruption of its systems due to the "Year 2000" problem, there can be no
assurance that the Company's suppliers and customers will not be adversely
affected by the "Year 2000" problem. Nonetheless, the Company believes that the
"Year 2000" issue will not have a material impact on the Company's business
operations or financial condition.

                                   BUSINESS


General

     The Company is a facilities-based provider of technologically advanced,
high-bandwidth, fiber optic transmission capacity for communications carriers
on local loop, inter-city and interstate facilities. The Company is currently
expanding its fiber optic network, the NEON system, to encompass approximately
1,000 route miles, or approximately 80,000 fiber miles, concentrated in the
Northeast. The Company believes that the Northeast, which in 1996 represented a
$29.3 billion telephony services market and which has one of the highest
population densities and concentrations of businesses, universities, phone
lines, personal computers and television sets in the country, is a region
characterized by significant and growing demand for broadband communications
infrastructure. The Company is constructing the NEON system utilizing primarily
electric utility ROWs, which allow the Company to provide secure fiber optic
capacity at competitive prices with access to virtually any location where the
local utility provides electrical service. The Company is using advanced fiber
optic technology in the NEON system, including non-zero dispersion shifted
fiber, dense wave division multiplexing optronics and SONET four-fiber ring
self-healing technology, to allow the Company's carrier customers to meet the
demand for reliable, high-bandwidth voice, data and video transmission capacity
in the Northeast. For example, a pair of fiber optic strands on the NEON system
can transmit up to approximately 10 gigabits of data per second, or the
equivalent of approximately 129,000 simultaneous voice conversations.

     The Company has already completed and currently operates fiber optic
routes from Hartford, Connecticut to Springfield, Massachusetts and from
Nashua, New Hampshire to Portland, Maine, totaling approximately 212 route
miles, or approximately 13,700 fiber miles. The Company is currently
engineering or constructing additional routes in New York, Connecticut,
Massachusetts and New Hampshire to create a continuous fiber optic link between
White Plains, New York and Portland, Maine with access into and around Boston,
Massachusetts and numerous other major cities in the Northeast. These
additional routes are expected to be substantially completed in 1998 and will
add approximately 380 route miles, or approximately 30,800 fiber miles, to the
NEON system. The Company is also planning to complete further expansion routes
in 1999 connecting New York City, Providence and other metropolitan areas to
the NEON system. The completion of routes under construction and currently
planned will enable the NEON system to connect more than 540 cities and towns
in six states and pass more than 200 POPs, tandem switches and central offices,
which the Company believes serve over 18 million people and over 470,000
businesses.

     Commencing in September 1994, the Company entered into a series of ROW
agreements with Northeast Utilities Service Company, a subsidiary of NU, the
largest electric utility service provider in New England, serving over 1.7
million customers in Connecticut, Massachusetts and New Hampshire, to build
fiber optic facilities utilizing NU's transmission and distribution
infrastructure, including utility towers, poles, underground ducts and urban
conduit systems. In January 1997, the Company entered into a similar ROW
agreement with CMP, the largest electric utility service provider in Maine,
serving over 500,000 customers, to build fiber optic facilities utilizing CMP's
transmission and distribution infrastructure. NU and CMP have also financed
substantially all of the construction and operations of the NEON system to date
and currently beneficially own (prior to the sale of shares in the Equity
Offering) 41.37% and 53.53%, respectively, of the Company's capital stock.

     The Company has pursued a strategy of establishing relationships with
electric utilities and building the NEON system utilizing primarily electric
utility ROWs. The Company believes that the use of such ROWs provides
significant advantages, including: (i) potentially ubiquitous inter-city and
intra-city coverage in the local electric utility's service territory,
including throughout downtown areas and directly into buildings, (ii) use of
existing electric transmission infrastructures, including towers, poles, ducts
and conduits, to achieve faster, less costly installation, (iii) generally more
secure and reliable routes than other ROWs, including railroad beds, streets
and highways, (iv) highly desirable redundant and geographically diverse fiber
optic routes for communications carriers and (v) establishment of an extensive
ROW network through negotiation with relatively few parties, rather than with
numerous parties such as municipalities, transit authorities and governmental
agencies.

     The Company currently intends to target only communications carriers as
customers, rather than end-users of telecommunications services. The Company
believes that this strategy allows it to: (i) maximize the Company's
opportunities to sell its capacity regardless of the end-user's selection of a
retail provider, (ii) avoid the significant initial and ongoing investment
required in selling, marketing and providing services to end-users, (iii)
attract carrier

customers that may be reluctant to contract with a direct competitor, (iv)
generate revenues quickly from carriers that are easily identifiable and
require large amounts of fiber optic capacity, and (v) lock in relatively
secure long-term revenue streams from customers that are generally more
creditworthy than end-users. Carrier customers typically lease fiber optic
capacity under multi-year contracts with which they enhance or develop their
own communications networks as a cost-effective alternative to constructing
their own infrastructure or purchasing measured services from other carriers
with whom they may compete. Carriers targeted by the Company include a broad
range of communication companies such as ILECs, CLECs, IXCs, paging, cellular
and PCS companies, cable television companies and ISPs. Currently, the Company
has contracts with Brooks Fiber (now owned by WorldCom), Teleport (expected to
be acquired by AT&T, MCI (expected to be acquired by WorldCom), Sprint and
Global NAPs, Inc., a regional ISP.

     The Company intends to offer its carrier customers leases of both dark
fiber (fiber optic transmission lines leased without optronics equipment
installed by the Company) and lit fiber (fixed amounts of capacity, such as
DS-1, DS-3, OC-3, OC-12, OC-48 and higher, on fiber optic transmission lines
that use the Company's optronics equipment) at fixed-cost pricing and over
multi-year lease terms. The Company intends to lease approximately one-third of
the available fibers in the NEON system as dark fiber and one-third as lit
fiber. In addition, the Company plans to reserve approximately one-third of its
available fibers for future services that the Company may provide to capitalize
on future technological advances or changes in the marketplace that the Company
expects to occur in the communications industry. Because of the geographic
flexibility and virtual ubiquity of the electric utility ROWs used in
construction of the NEON system, the Company expects that it will be able to
provide fiber optic connectivity for its carrier customers to and from
virtually any location in the NEON service territory, including intra-city
local loop facilities, inter-city long-haul or short-haul facilities, or a
combination of both.


History of the Company

     The Company was incorporated in 1989 in Massachusetts under the name
"FiveCom, Inc." to develop fiber-optic networks in secondary and tertiary
markets in the Northeast. Prior to 1994, the Company was the managing general
partner of a venture which built a CAP network in Springfield, Massachusetts
and also built several small private networks in eastern Massachusetts. In
February 1994, the Company sold its interest in the Springfield network to
Brooks Fiber. Following this sale, the Company expanded its business strategy
to include intra-LATA and long distance facilities using electric utility ROWs
and changed its focus to target carrier customers rather than end users.
Commencing in September 1994, the Company entered into the NU Agreements,
pursuant to which the Company obtained ROWs in the service territories of NU
and its subsidiaries. In 1996, the Company raised approximately $16.7 million
from private placements of equity securities to MaineCom and Mode 1. In January
1997, the Company entered into the CMP Agreement, under which the Company
obtained ROWs in CMP's service territory, and raised an additional $2.6 million
from CMP and other investors in a private equity financing. In 1998 the Company
was reincorporated in Delaware under the name "NorthEast Optic Network, Inc."

Market Opportunity

     The Company believes that there is a significant demand for high-bandwidth
communications services and a limited supply of technologically advanced dark
and lit fiber optic facilities in the Northeast to meet such demand. The
Company believes the needs of communications carriers for advanced,
high-bandwidth voice, data and video transmission capacity will increase over
the next several years due to various factors, including:

     Rapid Growth of Communications Traffic. The Company believes that total
telephony service revenue in the United States grew by approximately 9%
annually from 1992 to 1996, to $222.3 billion. Data traffic service grew by 28%
from 1996 to 1997 to $16 billion and is projected to grow by 38% to $22.1
billion in 1998. Much of this growth in data traffic is attributable to
increased Internet traffic and its corresponding demands for increased data
communications bandwidth. For example, the number of Americans using the
Internet is estimated to have grown from fewer than five million in 1993 to as
many as 62 million by the end of 1997. The Company believes that the growth of
communications traffic in the Northeast will be enhanced by the high population
density, income and education levels, number of phone lines per household and
other favorable demographic characteristics of the region. With its advanced
fiber optic transmission capacity, the Company believes that it will be
well-positioned to capitalize on this growth.


                                       33

     Capacity Required by New Entrants. Competition and deregulation are
attracting new entrants to the telecommunications market. The 1996 Act allows
the RBOCs to enter the long distance business upon meeting certain competitive
conditions and also eliminates certain barriers to entry in the local exchange
market. The 1996 Act also enables other entities, including entities affiliated
with power utilities and ventures between ILECs and cable television companies,
to provide a wider range of telecommunications products and services. The
Company believes that the deregulation of various telecommunications markets
will lead to an increase in the number of telecommunications providers needing
fiber optic transmission capacity as more parties choose to compete. The
Company believes that many carrier customers will choose to lease fiber optic
capacity from facilities providers such as the Company to enhance or develop
their own communications networks as a lower-cost alternative to constructing
their own infrastructure or purchasing measured services from other carriers.
The Company believes that the NEON system will provide a cost-effective
alternative for market entrants in a number of communications industry
segments, including ILECs, CLECs, IXCs, wireless companies, cable companies and
ISPs.

     Need for Redundant Routing and Geographic Diversity of ROWs. Carriers
require redundant paths throughout their networks to provide reliability in the
event of an equipment failure, break in one of their fiber lines or other
outage. In order to ensure the required redundancy, carriers typically build,
swap or lease capacity along fiber routes that do not share a common point of
potential failure. In the Northeast, however, there are relatively few pre-
assembled ROWs available to support new telecommunications infrastructure. As a
result, many carriers are unable to establish secure redundant routing when all
the carriers' routes run within the same ROWs. In the event such a common ROW
were to be damaged or cut, the consequences would be severe for the carriers
and their customers. This lack of geographic diversity of fiber optic routes in
the Northeast has created a substantial need for network capacity on new and
alternative ROWs, such as those offered by the Company.

     Expected Upgrades to Older Communications Networks. Many of the fiber
optic networks currently operated by existing carriers in the Northeast were
constructed prior to 1990, using asynchronous, non-SONET ring architecture and
using earlier generation fiber that cannot optimally deploy DWDM optronics for
high capacity transmission. The Company believes that these carriers will need
to improve or replace parts of their networks to complete the SONET ring
architecture and also add more high capacity fiber optic transmission lines to
remain competitive in the future. In addition, the Company believes that
approximately 92% of the RBOCs' networks currently are comprised of copper
cable located on antiquated infrastructure. The RBOCs will likely need to
replace or upgrade their networks to remain competitive and satisfy their
customers' increasing demand for reliable, high-bandwidth capacity in the
coming years. The Company believes that carriers with older, more limited
networks will seek cost-effective and expedient solutions when faced with the
decision to lease, buy or build fiber optic capacity which could result in
increased demand for the Company's fiber optic capacity.

     Accommodation of Multimedia and Other New Applications. The Company
believes that additional transmission capacity and faster response times will
be required to accommodate the needs of multimedia (voice, data and video) and
other potential high-bandwidth applications, including the deployment of
corporate intranets and wide area networks, and the use of the
telecommunications infrastructure for providing cable television and other
entertainment services. In addition, the Company's SONET technology and
high-bandwidth fiber optic capacity support advanced communications
applications, such as Frame Relay, ATM and IP platforms. The Company believes
that these capacity-intensive requirements will create significant demand for
its high quality, high-bandwidth fiber optic capacity.

     Carriers' Desire for Low-Cost Local and Regional Transport. The Company
believes that it has an opportunity to fill the needs of the predominant
interstate carriers that are building or have completed their backbone networks
to most of the Northeast's key LATAs. Generally, an IXC constructs a network
with trunk lines terminating into tandem switches in LATAs. To get from the
tandem switch to the end-user, or vice versa, IXCs typically pay to an LEC
access and egress charges, which often comprise the largest component of the
IXCs' transmission costs. For this reason, IXCs are seeking less costly,
alternative local access within LATAs. One alternative for the IXCs is to carry
their traffic deeper into the region's telecommunications base and to hand off
their traffic at a LEC host switch, which is located much closer to the
end-user than the tandem switch, or to terminate their traffic directly at the
customer's premises. Similarly, the Company believes that LECs with inter-LATA
traffic, including the RBOCs when they are permitted to provide long-distance
traffic, desire to minimize the transportation costs imposed by the IXCs and
are seeking lower cost, alternative regional transport. The NEON system, which
will connect into and around numerous cities and towns in the Northeast, can
provide such local access and regional transport.

Business Strategy

     The Company's objective is to become the preferred facilities-based
provider of fiber optic network capacity in the Northeast. The following are
the key elements of the Company's strategy to achieve this objective:

     Leverage Electric Utility ROWs.  The Company is pursuing a strategy of
building the NEON system utilizing primarily electric utility ROWs, which the
Company believes provide significant competitive advantages compared to
alternative ROWs in the Northeast such as railbeds and highways. Using electric
utility ROWs, the Company can provide fiber optic connectivity for its carrier
customers to and from virtually any location in the utilities' service
territory, including throughout downtown areas and directly into buildings. The
Company also intends to utilize existing, pre-assembled electric utility
transmission infrastructure, including towers, poles, ducts and conduits for
faster, less costly installation. In addition, since electric utility ROWs are
generally more secure than other ROWs and provide valuable geographic route
diversity for carriers, the Company can offer its customers highly reliable
primary and redundant network capacity. In addition to the Company's existing
ROW agreements with NU and CMP, the Company is currently pursuing additional
agreements with other utilities in adjoining territories to expand the
Company's network footprint and gain access to further ROWs through negotiation
with relatively few parties, rather than numerous municipalities, transit
authorities and governmental agencies.

     Target Carrier Customers. The Company intends to target communications
carriers as customers, rather than end-users of telecommunications services.
This enables the Company to maximize its opportunities to sell its capacity
regardless of the end-user's selection of a retail provider and to attract
carrier customers that may be reluctant to purchase services from a direct
competitor that serves the same retail market. Carrier customers are also
easily identifiable, which allows the Company to focus its sales and marketing
and customer services efforts and avoid the significant initial and ongoing
investment required to attract and retain numerous retail customers. In
addition, the Company believes that it can generate revenues more quickly from
carrier customers, which are generally more creditworthy than end-users,
require large amounts of fiber optic capacity and are more likely to make
long-term capital commitments in advance of the provision of services. To date,
the Company has entered into contracts with five carriers, including Brooks
Fiber/WorldCom, Teleport/AT&T, MCI/WorldCom, Sprint and Global NAPs, Inc., a
regional ISP.

     Reduce Construction and Operating Costs. The Company is reducing the
construction and operating costs of the NEON system in order to offer its
customers competitive prices while maximizing its operating margins and return
on investment. The Company is using primarily pre-assembled electric utility
transmission and distribution infrastructure, including towers, poles, ducts
and conduits, in the construction of the NEON system, which reduces the need to
obtain local permits, conduct surveys, cut tracks, install conduits and ducts
and erect towers and poles prior to installation. In addition, the Company's
electric utility ROWs provide easy and safe access to the fiber cable for low
cost maintenance and repair. The Company is also installing high fiber count
cable in the NEON system--64 to 96 fiber optic strands per cable in the routes
currently under construction and up to 144 to 432 fiber optic strands on future
installations, depending on the anticipated demand for a particular route. This
high fiber count reduces the Company's fiber cost per mile and provides reserve
capacity, which will reduce the cost of providing additional services in the
future. The Company's newly-constructed network also provides significant
operating and maintenance cost advantages because of the high quality, advanced
fiber optic technology utilized by the NEON system.

     Build a Reliable, Technologically Advanced Network. The Company believes
that the characteristics of its network will allow it to meet its customers'
demands for reliability and high capacity. The Company is constructing the NEON
system utilizing bi-directional, self-healing SONET four-fiber ring
architecture primarily on electric utility ROWs, which allow for enhanced
physical security and more geographic flexibility than other ROWs. The Company
uses both non-zero dispersion shifted Truewave[RegTM] fiber and conventional
single-mode fiber manufactured by Lucent Technologies Inc., which the Company
believes to be the highest quality fiber optic cable available. The Company is
also using Nortel's DWDM optronics and forward error correction technology at
high OC levels that enable the highest commercially available transmission
capacity (OC-192) and data integrity level (10(-15) Bit Error Rate). The NEON
system can also accommodate advanced communications applications such as Frame
Relay, ATM and IP.

     Focus on High Demand Northeast Market. The Northeast is one of the most
densely-populated regions of the United States. The Company believes that the
Northeast market, which in 1996 represented a $29.3 billion telephony services
market and which has one of the highest concentrations of businesses,
universities, phone lines,


                                       35
<PAGE>

personal computers and television sets in the country, is a region
characterized by significant and growing demand for broadband communications
infrastructure. The Northeast market is dependent in part upon antiquated
communications infrastructure currently lacking sufficient fiber optic
capacity, route diversity and redundancy. The Company's strategy is to focus on
serving the present and future needs of this market by constructing and
operating a technologically advanced network offering (i) more capacity, (ii)
enhanced capabilities, such as SONET ring architecture and route diversity, and
(iii) near-ubiquitous coverage.

     Leverage Management Experience. The Company's management team includes
individuals with significant experience in the telecommunications and utility
industries which will be important in the buildout of the NEON System. Victor
Colantonio, the Company's founder and President, has 25 years experience in the
telecommunications industry having previously served as President of
International Communications Services Corp. and Murray International Inc.,
providers of network services to AT&T, Southern New England Telecommunications
Corporation ("SNET") and Sprint, among others. The Company's Chairman and Chief
Executive Officer, Richard Crabtree, has 27 years of utility experience
including serving as Chief Financial Officer of CMP. William Fennell, the
Company's Chief Financial Officer and Treasurer, held several positions at GTE
over 16 years before becoming Chief Financial Officer of Philips Electronics
Group of North America. James Mack, the Company's head of sales, has worked in
the telecommunications industry since 1966 having held various sales positions
at Bell Atlantic and NYNEX. The Company's head of operations, Michael Musen,
has spent 18 years in telecommunications having previously worked at a provider
of network systems.

     Leverage Utility Relationships. The Company intends to leverage its
relationships with NU and CMP. The Company directly benefits from these
relationships for the following reasons: (i) the Company believes relationships
with electric utilities enhance the Company's credibility with large carrier
customers and facilitates new customer contracts with such carriers, (ii) the
Company outsources substantially all of its engineering and design, maintenance
and repair requirements to NU and CMP, thereby increasing the Company's mission
critical preparedness and the reliability of the Company's network and
enhancing the Company's ability to respond to emergency repair needs, (iii) NU
and CMP have significant resources and experience in the engineering and
construction of large transmission and distribution networks and (iv) the
Company's experience with NU and CMP creates opportunities to establish
relationships with other electric utility companies. The Company is currently
in the process of developing relationships with additional electric utilities.


The NEON System

     The NEON system is a technologically-advanced, high-bandwidth, fiber optic
network that the Company is constructing primarily using electric utility ROWs
in the Northeast and that the Company intends to expand into a communications
system serving numerous cities and towns in six states. The Company has
completed and currently operates fiber optic routes from Portland, Maine to
Nashua, New Hampshire and Springfield, Massachusetts to Hartford, Connecticut
totalling approximately 212 route miles, or approximately 13,700 fiber miles.
The Company is currently engineering or constructing additional routes in New
York, Connecticut, Massachusetts and New Hampshire, to create a continuous
fiber optic link between White Plains, New York and Portland, Maine with access
into and around Boston, Massachusetts and numerous other major cities in the
Northeast. These additional routes are expected to be completed in 1998 and
will add approximately 380 route miles, or approximately 30,800 fiber miles, to
the NEON system. The Company is planning to complete further expansion routes
in 1999 connecting New York City, Providence and other metropolitan areas to
the NEON system. Upon completion of routes under construction or currently
planned, the NEON system will extend over 1,000 route miles or over 80,000
fiber miles, connect more than 540 cities and towns in six states and pass more
than 200 POPs, tandem switches and central offices, which the Company believes
serve over 18 million people and over 470,000 businesses.

</TABLE>

     The Company acquires its ROWs principally from electric utilities in the
territory covered by the NEON system. The Company believes that such ROWs are
superior to alternative ROWs available in the Northeast, namely, those along
railbeds and highways, because electric utility ROWs provide near-ubiquitous
coverage at lower cost and because deviations from railbed or highway ROWs
often entail significant expenditures and a lengthy and expensive community-
by-community approval process. Furthermore, installing cable in electric
utility ROWs is often safer, easier and faster, because the cable is placed in
existing underground conduits and ducts or installed on existing towers and
poles. With rail beds and highways cable must often be buried in trenches, a
process often hampered by accommodating commuter rush hours, complying with
stringent environmental laws, crossing water, trenching and blasting bedrock.
In addition, using primarily electric utility ROWs, the NEON system has the
potential to provide communications connections to nearly every building,
business park and industrial complex in its service territory.


     The Company uses three cost-effective methods for installing its fiber
optic cable and taking advantage of the pre-assembled and pre-existing electric
utility infrastructure in the Company's ROWs, including utility transmission
structures (towers) and distribution infrastructure (poles, civil works and
conduit). The first is to replace existing ordinary ground wire (which is used
to provide lightning protection atop utility structures) with optical phased
ground wire ("OPGW"), which is custom-made for the Company and contains up to
96 fiber strands currently and up to 144 fiber strands in future sheath
designs. The second method is to install new all dielectric (non-conductive)
self-support fiber optic cable ("ADSS") under the electrical conductors on
electric transmission structures. ADSS is capable of carrying up to 288 fiber
strands currently and up to 432 fiber strands in future designs. Finally, in
underground utility conduits, the Company uses conventional optical cable made
for underground conditions.

Advanced Technology

     The Company uses state-of-the-art technology in the NEON system. The NEON
system consists of fiber optic communication paths, which allow for high speed,
high quality transmission of voice, data and video communications. Fiber optic
systems use laser-generated light waves to transmit voice, data and video in
digital formats through ultra-thin strands of glass. Fiber optic systems are
generally characterized by large circuit capacity, are resistant to external
signal interference and directly interface to digital switching equipment or
digital microwave systems. The Company is currently installing fiber optic
cable containing between 64 and 96 fiber optic strands and in the future may
install up to 144 or 432 fiber optic strands per cable depending on anticipated
demand for the particular route. Each of these fiber optic strands is capable
of transmitting significantly greater bandwidth than traditional analog copper
cables. Using current fiber optic transmission optronics, a single pair of
fiber optic strands used by the Company's network can transmit up to 10
gigabits of data per second or the equivalent of approximately 129,000
simultaneous voice conversations. The Company believes that continuing
developments in compression technology and multiplexing equipment will increase
the capacity of each fiber optic strand, thereby providing more bandwidth
carrying capacity at attractive incremental costs.

     The technologies employed by the Company in the construction and operation
of the NEON system include Lucent's non-zero dispersion shifted fiber and
Nortel's DWDM optronics possessing forward error correction technology at high
OC levels that enable the highest commercially available capacity transmission
(OC-192) and data integrity level (10(-15) Bit Error Rate). The Company believes
that the advanced technical operating characteristics of the NEON system will
enable it to provide highly reliable services to its customers at low costs by
permitting higher capacity transmission over longer distances between
regeneration and amplifier facilities than can be provided by less advanced
fiber systems. See "Risk Factors--Rapid Technological Change."

     The Company offers end-to-end fiber optic capacity utilizing
bi-directional SONET four-fiber ring architecture, which has the ability to
route customer traffic in two directions around a ring design thereby
minimizing service interruptions due to fiber cuts. Currently, the NEON system
is continuously monitored to maintain quality control on a 24-hour basis and to
alert the Company of any degradation of signal or loss of fiber capacity, and
to pinpoint the location of such difficulty and enable the Company to repair or
replace impaired fiber quickly.


Right-of-Way Agreements

     The following is a summary of the Company's agreements that provide for
most of the ROWs currently used in the NEON system, and a summary of the status
of the Company's efforts to obtain the additional ROWs required for the system.
In addition to the agreements set forth below, the Company has a number of
agreements with Bell Atlantic to use certain ROWs along pole lines and within
ducts in various areas throughout the Northeast to supplement its primary means
of procuring ROWs.


NU Agreements

     In 1994 and 1995, the Company entered into a series of agreements (as
subsequently amended and restated in February 1998, the "NU Agreements") with
NU and four of its operating subsidiaries concerning the provision of ROWs
along electric utility towers and inside urban electric utility ducts. Pursuant
to the NU Agreements, the Company acquired indefeasible rights of use ("IRUs")
in fiber optic filaments placed along NU's ROWs prior to February 1998 and
acquired ownership of fiber optic filaments placed along NU's ROWs subsequent
to February 27, 1998 along with an IRU in the ROWs themselves (collectively,
the "NU System"). NU and the Company both agreed to use their best efforts to
complete installation of the NU System by September 27, 1999. The Company
agreed to pay the cost of installing the cable and to utilize NU's engineering
staff in carrying out the installation. The Company is allowed to treat as its
own property for tax and accounting purposes that portion of the NU System for
which NU holds title. Under the Agreements, the Company agreed to pay to NU an
annual fee beginning in 2004, and a percentage of the gross revenues of the
Company generated by the NU System upon achieving certain revenues.

     A portion of the NU System, composed of 12 fibers within the cable, has
been set aside for NU's use ("NUNet"). NU may lease these fibers to third
parties, provided that prior to September 27, 1999, NU is not permitted to
assign any fibers or resell capacity on NUNet to certain specified carriers
except for certain limited purposes. After September 27, 2001, NU will be free
to use NUNet to compete with the Company.


                                       38
<PAGE>

     Under the NU Agreements, if the Company wishes to extend the NEON system
along certain routes, or if any proposed segment of the NEON system's route
requires material modifications or unusual expense to make it available for the
Company's fiber, or if NU withdraws any segment from the route in order to give
priority to electrical services, the Company has the right to designate
additional or alternative route segments, subject to NU's approval, which shall
not be withheld unless such additional or alternative segments would materially
adversely affect NU's ability to provide reliable electric service, cause or
create safety problems or would not be feasible for structural reasons. If NU
desires to create new route segments in order to extend the NU System, the
Company has a right of first refusal on the provision of any such segments. If
NU obtains such segments from third parties, NU has agreed to use its best
efforts to obtain for the Company the unimpeded use of not less than 12 usable
singlemode fibers in such segment on terms no less favorable to those provided
to NU.

     The NU Agreements have an initial term of 30 years and expire on September
27, 2024. Thereafter they automatically renew for five year terms, unless one
of the parties has given a one-year advance notice of termination. In the event
that NU gives such a notice and terminates the Agreements, it must either, at
its option, pay to the Company an amount equal to the fair market value of the
NU System less NUNet or allow the Company to retain its IRUs and receive from
the Company an annual payment equal to 10% of the Company's gross revenue from
the NU System, which payment would be in addition to the other annual payments
under the NU Agreements.

     In addition to the foregoing, the NU Agreements may be terminated by NU if
the Company defaults in the performance of certain of its obligations under the
NU Agreements, including the failure to establish NUNet by September 27, 1999,
the failure to obtain and maintain all necessary government permits, licenses,
franchises and approvals, and the failure to pay amounts due by it under the NU
Agreements subject in most cases to cure periods of between 30 and 90 days.


CMP Agreement

     In January 1997, the Company entered into an agreement with CMP (the "CMP
Agreement") in which CMP granted the Company a right of use in fiber optic
filaments within a cable as it is placed along a certain route in the CMP ROW
(the "CMP System"). CMP and the Company both agreed to use their best efforts
to complete installation of the CMP System by January 7, 1999. The Company has
the right to install additional cable upon CMP's ROW, subject to the approval
of CMP, which must not be unreasonably withheld. The Company is obligated to
pay the cost of installing the cable. Title to and ownership of the CMP System
is to be held by CMP, but the Company is allowed to treat the CMP System as its
own property for tax and accounting purposes.


     In exchange for the rights of use, the Company agreed to pay to CMP an
annual fee beginning, with regard to any particular route segment, in the first
calendar year following the installation date for such route segment (the
"Installation Date").


     The Company's rights of use do not apply to 6 fibers that have been set
aside for CMP's use ("CMPNet"). CMP may use these fibers for its own business
purposes, but may not lease them to third parties prior to the seventh
anniversary of any given Installation Date. After such seven year period, to
the extent that CMP has excess capacity on CMPNet, CMP is required to negotiate
in good faith with the Company to provide such excess capacity to the Company
before making it available to third parties. If the Company does not enter into
an agreement with CMP with respect to such excess capacity, CMP will be able to
use such capacity to compete with the Company.


     The CMP Agreement has an initial term of 30 years and expires on January
7, 2027. Thereafter it is renewable at the option of the Company for an
additional ten-year term. In the event that the Company elects to renew the CMP
Agreement, it must pay to CMP an annual payment equal to 10% of the Company's
pre-tax gross annual revenue from the CMP System, which payment would be in
addition to the other annual payments under the CMP Agreement.


     In addition to the foregoing, the CMP Agreement may be terminated by CMP
if the Company defaults in certain of its obligations under the CMP Agreement
and such default is not cured within a designated cure period.

Services

     The Company generally leases high capacity transmission services for use
by various communications carriers. The Company's customers include
facilities-based carriers that require transmission capacity where they have
geographic gaps in their facilities, need additional capacity or require
alternative or redundant routing, and non-facilities-based carriers requiring
transmission capacity to carry their customers' telecommunications traffic.

     The Company currently leases dark fiber and lit fiber, as described below,
and has also reserved fibers for future uses.


     Dark Fiber
     The leasing of dark fiber allows a carrier to interconnect any two or more
specific points on the NEON system. This product requires the Company to
install a fiber optic patch panel ("FOPP"), which is the minimal customer
premise equipment installed by the Company. Dark fiber leases allow a carrier
to install its own opto-electronic equipment and to use as much or as little
capacity as it desires and to customize its capacity with feature rich
technology and its network protocols that differentiate that carrier's product
offerings from others. As a result, the carrier can deploy the dark fiber for
whatever purpose it chooses while the Company remains transparent to the
carrier's end-user.

     Whenever possible, the carrier customer is restricted from using the dark
fibers for purposes other than supporting its own customers. To date, the
Company has placed restrictions on the transfer or assignment of the leased
fiber from one carrier to another. In addition, the lease prohibits carriers
from accessing its leased fibers at any point other than those designated in
the lease; therefore carriers cannot add additional traffic or draw off traffic
along the path.


     Lit Fiber
     Pursuant to fiber leases, the Company provides a specific amount of
capacity between any two or more points on the NEON system as specified by the
carrier. Lit services involve the installation of opto-electronic terminals by
the Company, to the carrier's specifications, that "light" the fiber and
transmit/receive capacity on the network. The Company intends to provide lit
transport capacity initially at SONET OC-3, OC-12, OC-48 and higher rates. In
the future the Company intends to provide carriers with services at the lower
DS-3 and DS-1 levels.


     Reserved Fiber
     Part of the Company's strategy is to reserve approximately one-third of
the fibers comprising the NEON system in order to have the capacity necessary
to take advantage of changes in telecommunications technology and services and
to meet future anticipated market demand. The Company believes that continuing
improvements in telecommunications technology will alter the way in which such
services are provided as well as the level of demand for such services. These
changes include developments in compression and multiplexing technology, as
well as changes in communications protocols. These changes will likely effect a
change in the nature of services provided by the Company's customers and,
thereby, a change in the nature of the services provided by the Company. In
addition, such changes may open new opportunities for the Company, including
opportunities to serve new classes of customers. Because the exact nature and
effect of such changes are, at present, difficult to measure, the Company
believes it prudent to retain capacity that is not committed to any particular
use or technology but can be brought out of reserve when the impact of such
technological changes becomes clear. In the meantime, the Company may enter
into short-term agreements with respect to such reserved capacity for the
provision of its current services if such opportunities arise.


Sales and Marketing

     The Company's sales and marketing strategy includes positioning itself as
the carriers' carrier of choice, emphasizing its capacity, reliability, rapid
deployment, customer service, potential for near-ubiquitous access in its
service territory and the cost advantages that will allow the Company to lease
its fiber optic infrastructure at competitive fixed prices. The Company intends
to price its services below what the Company believes it would cost carriers to
construct their own facilities or to obtain capacity from other sources.

     The Company also believes that communications carriers will be attracted
to the Company's dark fiber product. The contracts that the Company has signed
to date arose as a result of management's long standing relationships


                                       40
<PAGE>

in the telecommunications industry. The Company intends to leverage these
relationships and increase customer scope and penetration through a small,
dedicated sales force.


Customers

     The Company is targeting other telecommunications carriers as customers
and does not intend to offer its services directly to the end-users. The NEON
system enables carriers to link geographically separated central offices and
POPs with primary or redundant connections in their networks. The Company's
facilities also enable carriers to connect their networks directly into the
premises of the carriers' end-users.

     The Company currently has contracts with Brooks Fiber (now owned by
WorldCom), Teleport (expected to be acquired by AT&T), MCI (expected to be
acquired by WorldCom), Sprint and Global NAPs, Inc., a regional ISP. In
addition, the Company is currently in the process of negotiating agreements
with certain other major communications carriers. There can be no assurance
that such agreements will be consummated or will be on terms as favorable to
the Company as its existing agreements.

     The Company's potential carrier customer base includes the following
classes of carriers:

[bullet] Incumbent Local Exchange Carriers & Independent Telcos, such as Bell
         Atlantic, SNET, Standish Telephone Co. (ME), Wilton Telephone Company,
         Inc. (NH) and Saco River Telephone Co. (ME). ILECs typically require
         some interstate paths for internal communications, signal control and
         operator services. ILECs also require intrastate capacity to connect
         central offices to one another and to connect central offices to POPs
         and customer premises.

[bullet] Facilities Based IXCs, such as AT&T, Sprint, MCI/WorldCom/LDDS, WilTel,
         Frontier, Qwest, IXC Communications, Inc., Cable & Wireless PLC, Level
         3 Communications, Inc. and others. IXCs typically require (i) regional
         short-haul connectivity from their national backbone facilities to
         originate and terminate traffic deeper into the customer base, (ii)
         redundant routing to ensure reliability in their networks, and (iii)
         additional capacity for their customers as minutes-of-use and IP
         bandwidth requirements increase.

[bullet] Competitive Local Exchange Carriers, such as WorldCom/Brooks Fiber,
         AT&T/Teleport, WorldCom/MFS Communications Company, Inc., RCN
         Corporation, MCImetro, Intermedia Communications Inc., NextLink
         Communications, Inc., ICG Communications, Inc. and others. CLECs
         typically require interconnection between their local networks and
         extensions further into the community.

[bullet] Internet Service Providers, such as MCI, GTE Corporation/BBN, Bell
         Atlantic, WorldCom/Gridnet, WorldCom/UUNet Technologies Incorporated,
         Sprint, RCN Corporation, HarvardNet, MediaOne and others. ISPs
         typically require distribution channels to IXC and LEC switches and
         interconnection to ISP switches.

[bullet] Cable Television Companies and Video Carriers, such as MediaOne Group,
         Inc. (U S West, Inc.), Time Warner Inc., Cablevision Systems
         Corporation, Cox Communications, Inc., Vyvx, NECN, Public Broadcasting
         Service affiliates, broadcasters and others. Cable companies typically
         require fiber optic capacity to upgrade their systems to higher speed
         bandwidths, which allow them to increase the number of channels
         available, add interactive programming and Internet and data transfer
         capabilities and to consolidate head-end facilities. Broadcasters
         typically require inexpensive video paths to extend their reach to
         distant locations.

[bullet] Wireless Communication Companies, such as SNET Links, Bell Atlantic
         Mobile, CellularOne, Sprint PCS, OmniPoint, AT&T Wireless, STV Group,
         Inc., WinStar Communications, Inc., NextWave Telecom Inc., NorthCoast,
         Opcse-Galloway, Personal Communications, ACC-PCS (TCG), Devon Mobile,
         Vtel Corporation and others. Wireless companies typically require
         land-based back-hauling of traffic from towers to their switches and
         also capacity between their switches with IXCs, POPs, and ILECs central
         offices.

[bullet] Microwave Carriers, such as Eastern Microwave Inc./Intermedia
         Communications Inc. Microwave carriers typically require fiber optic
         capacity to replace microwave service as their primary source of
         communications capacity.

Competition

     The telecommunications industry is highly competitive, and the Company
faces substantial competition. Many of the Company's existing and potential
competitors have financial, management and other resources that are
substantially greater than those of the Company, as well as other competitive
advantages, including established reputations in the communications market. See
"Risk Factors--Competition."

     The Company is currently aware of communications carriers that own or
lease fiber optic networks in New England (such as AT&T, MCI, Sprint, Bell
Atlantic, Southern New England Telecommunications Corporation, WorldCom,
Teleport and MFS Communications Company Inc.) and of other carriers (such as
IXC Communications, Qwest Communications International Inc., Metromedia Fiber
Network Inc., Level 3 and RCN Inc.) who are planning to own or lease additional
networks which, if constructed, could employ advanced technology comparable to
that of the NEON system.

     Qwest recently acquired 288 miles of fiber optic cable between New York
and Boston, connecting such cities as Providence and Greenhill in Rhode Island
and New London, New Haven, Bridgeport and Stamford in Connecticut. Similarly,
IXC Communications, Inc. has recently acquired 280 miles of dark fiber between
New York and Boston. Another company, RCN Corporation, is engaged in the
construction of fiber optic networks in Boston and several surrounding
communities and in New York City. The Company's customers and potential
customers, such as MCI and AT&T, also have facilities available to them in the
region which could be used to compete with the Company. Development of fiber
optic networks is also continuing on a national scale; for example, Frontier
Corp. is currently in the midst of constructing a cross-continental long
distance fiber optic network from Los Angeles to New York and Qwest is
constructing a fiber-based national backbone network which will connect 115
metropolitan areas and span approximately 16,000 miles. In addition, other
companies, including Level 3 Communications, Inc., are planning nationwide and
regional networks of their own. These networks enable their owners either to
operate dedicated facilities for themselves or to install excess fiber to lease
to other communications carriers and large corporate, government or other
customers seeking high-bandwidth capacity. Alternatively, some network owners,
typically CLECs, may choose to use their infrastructure to provide switched
voice and data services, competing directly with ILECs and IXCs. Currently, the
Company does not provide such services or plan to provide such services. See
"Risk Factors--Limited Nature of Company's Services."

     In the cities connected by the NEON system, the Company also faces
significant competition from the ILECs, which currently dominate their
respective local markets. In addition, the Company faces competition from CLECs
and wireless competitors in the cities in which the Company plans to build its
networks.

     Most communications carriers already own fiber optic cables as part of
their communications networks, and each of these carriers could, and some do,
compete directly with the Company in the market for leasing fiber capacity.

     Some local cable television companies have extensive coaxial cable
networks in place that have been or could be further upgraded to fiber optic
cable. To the extent that local cable television companies decide to equip
their networks with fiber optic cable, they are potential direct competitors of
the Company provided that these competitors are willing to offer this capacity
to all of their customers.

     The Company also faces potential competition from both NU and CMP, both of
which have rights to use fibers in certain portions of the NEON system, which
use may include competition with the Company. See "--Right-of-Way Agreements."


Properties

     The NEON system and its component assets are the principal properties
currently owned by the Company or with respect to which the Company has an IRU.
The Company owns substantially all of the communications equipment required for
its business and holds certain ownership interests in the cable comprising the
NEON system. The Company's installed fiber optic cable is laid under the
various rights-of-way held by the Company. See "--Right-of-Way Agreements."
Other fixed assets are located at various leased locations in geographic areas
served by the Company.


                                       42
<PAGE>

     The Company's executive, administrative and sales offices are located at
its principal office in Waltham, Massachusetts. The Company leases this space
(approximately     square feet) under an agreement that expires in June 2000.


Reorganization

     The Company was incorporated in Massachusetts in July 1989 under the name
"FiveCom, Inc." In May 1996, FiveCom LLC, an operating subsidiary
majority-owned by the Company, was organized in Massachusetts. Also in May
1996, FiveCom LLC and Mode 1 Communications, Inc. ("Mode 1"), a subsidiary of
NU, organized NECOM LLC in Massachusetts, with FiveCom LLC owning approximately
60%, and Mode 1 owning approximately 40% of the membership interests in NECOM
LLC. In December 1996, FiveCom LLC and MaineCom Services ("MaineCom"), a
wholly-owned subsidiary of CMP, organized FiveCom of Maine LLC in
Massachusetts, with MaineCom owning 66.67%, and FiveCom LLC owning 33.33%, of
the membership interests in FiveCom of Maine LLC.

     In order to simplify the corporate structure and in contemplation of the
Offerings, the Company's major stockholders decided to reorganize the Company.
In       1998, (i) CMP exercised its warrants to purchase 5,876 shares of
membership interests in FiveCom LLC; (ii) each of the minority members in
FiveCom LLC (including NU and CMP), Mode 1 and MaineCom exchanged their
membership interests in FiveCom LLC, NECOM LLC and FiveCom of Maine LLC,
respectively, for shares of the Series B Convertible Preferred Stock of the
Company; (iii) FiveCom LLC, FiveCom of Maine LLC and NECOM LLC were each merged
with and into a wholly-owned subsidiary of the Company; and (iv) the Company
was reincorporated in Delaware under the name "NorthEast Optic Network, Inc."
and the Company's Certificate of Incorporation was amended and restated. The
actions described in the preceding sentence are referred to in this Prospectus
as the "Reorganization."


Regulation

     While the Company believes it is not directly subject to common carrier
regulation (except through its subsidiaries in Connecticut and New York), it is
part of an industry that is highly regulated by federal, state and local
governments whose regulatory actions are often subject to judicial
modification. The Company has not been subject to such regulation because it
has not offered its facilities to the general public nor has it engaged in the
provision of telecommunications services, generally the two actions that
subject an entity to such regulation. In light of the changes that are
occurring in the regulation of telecommunications, the Company cannot forecast
whether or not it will be subject to additional regulation in the future. In
Connecticut and New York the Company has petitioned to be recognized as a
regulated service provider because of the nature of its activities in, and the
statutory provisions of, those two states.


Federal

     Federal regulation has the greatest impact on the telecommunications
industry and has undergone major changes in the last two years as the result of
the adoption by Congress of the Telecommunications Act of 1996 ("the 1996 Act")
on February 8, 1996. The 1996 Act is the most comprehensive reform of the
nation's telecommunications laws since the Communications Act was enacted. The
1996 Act imposes a number of access and interconnection requirements on
telecommunications carriers and on all local exchange providers, including
CLECs, with additional requirements imposed on ILECs. The 1996 Act provides a
detailed list of items which are subject to these interconnection requirements,
as well as a detailed set of duties for all affected carriers. All
telecommunications carriers must interconnect with the facilities of other
carriers and not install features that will interfere with the interoperability
of networks. All LECs, including CLECs, have a duty to (i) not unreasonably
limit the resale of their services, (ii) provide number portability if
technically feasible, (iii) provide dialing parity to competing providers, and
nondiscriminatory access to telephone numbers, directory assistance, operator
services and directory listings, (iv) provide access to poles, ducts, conduits
and rights-of-way and (v) establish reciprocal compensation arrangements for
the transport and termination of telecommunications. In addition to those
general duties of all LECs, ILECs have additional duties to (i) interconnect at
any technically feasible point and provide service equal in quality to that
provided to their customers or the ILEC itself, (ii) provide unbundled access
to network elements at any technically feasible point at just, reasonable and
nondiscriminatory rates, terms and conditions, (iii) offer retail services at
wholesale prices for the use of telecommunication carriers, (iv) provide


                                       43
<PAGE>

reasonable public notice of changes in the network or the information necessary
to use the network or which affect interoperability and (v) provide for
physical collocation. "Physical collocation" is an offering by an ILEC that
enables another telecommunications carrier to enter the ILEC's premises to
install, maintain and repair its own equipment that is necessary for
interconnection or access to the ILEC's network elements. An ILEC must allocate
reasonable amounts of space to telecommunications carriers on a first-come
first-served basis. If space limitations or practical or technical reasons
prohibit physical collocation, an ILEC must offer "virtual collocation," by
which the other telecommunications carrier may specify ILEC equipment to be
dedicated to its use and electronically monitor and control communications
terminating in such equipment.

     The FCC adopted pricing and other guidelines to implement the
interconnection provisions of the 1996 Act, but the 8th Circuit Court of
Appeals recently vacated many of the FCC's guidelines. The responsibility for
setting pricing and other guidelines with respect to interconnection has thus
been left up to the individual state public service commissions. It is expected
that varying pricing and guidelines will emerge from state to state and some of
these guidelines may eventually have an indirect adverse effect on the
Company's business.

     Aside from the impact of the 1996 Act, the Company believes federal
regulation does not impact the Company directly because the Company is not
currently regulated as a common carrier under federal law. Federal
telecommunications law imposes special legal requirements on "common carriers"
who engage in "interstate or foreign communication by wire or radio for hire."
The Company believes that the leasing of fiber facilities does not constitute
engaging in the transmission of "communications by wire or radio" and therefore
is not subject to these legal requirements. In any event, the Company does not
intend to offer its fiber facilities as a common carrier. Common carriers are
those who offer telecommunications services directly to the public for a fee.
The Company does not intend to offer its fiber capacity in this manner, but
instead intends to enter into individual agreements on a selective basis with
prospective lessees of its fiber facilities. The Company therefore does not
believe that its fiber offerings are subject to the common carrier provisions
of the Communications Act. These conclusions reflect the Company's view that
there is no material difference from a regulatory perspective between the
leasing of dark and lit fiber, both of which are offered by the Company. The
difference between the two forms is that in the leasing of lit fiber the
Company provides a multiplexer and an interface (typically a patch panel) into
which the signal controlled by the customer is fed. Lit fiber generally has
lower capacity than dark fiber and therefore is more economical for some
customers with lower traffic volumes to transmit. There is, however, no
assurance that the FCC may not take the position that because of the
involvement by the Company in making the fiber transmission capable, in the
case of lit fiber, the leasing of such fiber is subject to regulation under the
Communication Act or that even the offering of dark fiber itself is subject to
regulation.

     The two subsidiaries of the Company which have applied for authority to
provide telecommunications services in New York and Connecticut will be subject
to regulation under the Communications Act.

     In addition to regulation of common carriers, federal telecommunications
law also imposes special legal requirements on "telecommunications carriers."
The law essentially defines "telecommunications carriers" as those offering
certain telecommunication services "directly to the public" or such classes of
users as to be effectively available directly to the public, regardless of the
facilities used. The Company therefore believes that a company has to be a
common carrier in order to be considered a telecommunications carrier. For the
reasons stated above, the Company believes that it is not a common carrier and
therefore that it is also not a telecommunications carrier with respect to its
fiber capacity leases. Nevertheless, the law is not entirely clear as to, and
the FCC has not definitively addressed whether, the term "telecommunications
carriers" is meant to encompass only common carriers, and therefore whether a
provider of fiber facilities on an individualized basis, like the Company, is a
"telecommunications carrier." The FCC has been petitioned by certain railroad,
power and telecommunications associations, none of which are affiliated with
the Company, to clarify the status of fiber providers in this respect, and if
the agency decides that such companies are telecommunications carriers, then
the Company would be subject to certain additional regulatory requirements.
These requirements could have a material adverse effect on the Company.

     If the Company were deemed to be a common carrier it would be required,
with respect to its telecommunications services, to (1) provide such services
indiscriminately upon any reasonable request; (2) charge rates and adopt
practices, classifications and regulations that are just and reasonable; (3)
avoid unreasonable discrimination in charges, practices, regulations,
facilities and services; (4) ensure that its services are accessible to and
usable by persons with disabilities; (5) pay into federal funds for
Telecommunications Relay Services and the North American Numbering
Administration; (6) assure that its networks comply with the requirements of
the Communications Assistance for Law Enforcement Act; (7) be subject to
government oversight and limitations on


                                       44
<PAGE>

its transactions with affiliates; (8) limit its use of Customer Proprietory
Network Information (CPNI) to provisioning of the services in connection with
which the CPNI was obtained; (9) be subject to the complaint process at the
FCC; and comply with various reporting, regulatory fee payment and other
requirements. The Company might also be required to file tariffs setting forth
the rates for its services. These regulatory requirements could impose
substantial burdens on the Company.

     If the Company's offering of fiber facilities were deemed to constitute a
"telecommunications service," or the provision of "telecommunications" for a
fee (unless deemed de minimis) then its revenues from fiber leases to end users
(but not to most other telecommunication carriers) would become subject to
assessment for the FCC's Universal Service Fund, a fund that was established by
the FCC pursuant to the 1996 Act to assist in ensuring the universal
availability of basic telecommunications services at affordable prices. This
assessment could create a liability equal to a percentage of the gross revenues
from these leases although the FCC has not announced what the annual assessment
will be (the Company anticipates, based on quarterly contribution factors as of
May, 1998 that the annual rate of assessment will be approximately 4.5% of
gross interstate end-user revenues for the year 1998, and may be higher in
subsequent years). The Company also may be liable for assessments by state
commissions for state universal service programs. The Company does not
anticipate that its aggregate liability for these universal service programs
would be material. In addition, since the revenues of the Company's competitors
will be subject to comparable assessments; this should not reduce the Company's
competitiveness.

     Federal telecommunications law may also affect the Company's business by
virtue of the inter-relationships that exist among the Company and ILECs and
IXCs. For example, the FCC recently issued an order requiring, among other
things, that common line access fees charged to IXCs, which previously amounted
to more than what was necessary to recover the costs of providing access, shift
from being usage driven to a fixed flat cost-based structure. While it is not
possible to predict the precise effect the access charge changes will have on
the Company's business or financial condition, the reforms will reduce access
charges paid by IXCs, likely eliminating one of the principal disincentives for
use of ILEC facilities by IXCs, which could have a material adverse effect on
the use of the Company's fiber optic telecommunications networks by IXCs.

     The FCC has responsibility under the 1996 Act's interconnection provisions
to determine what elements of an ILEC's network must be provided to competitors
on an unbundled basis. The FCC has decided not to declare fiber an unbundled
network element under these provisions. This decision is currently subject to
petitions for reconsideration before the FCC. An FCC decision to alter this
decision on reconsideration could decrease the demand for fiber provided by the
Company. In addition, the FCC has announced that state commissions may decide
to add network elements to the FCC's list of elements that are required to be
unbundled by all carriers throughout the country.


     State
     The 1996 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 FCC policies, any dedicated transmission service or
facility that is used more than 10% of the time for the purpose of inter-state
or foreign communication is subject to FCC jurisdiction to the exclusion of any
state regulation. Notwithstanding these prohibitions and limitations, states
regulate telecommunications services, including through certification of
providers of intrastate services, regulation of intrastate rates and service
offerings, and other regulations and retain jurisdiction under the 1996 Act 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.

     The state regulatory environment varies substantially from state to state.
At present, the Company does not anticipate that the regulatory requirements to
which it will be subject in Connecticut, Maine, Massachusetts, New Hampshire,
New York and Rhode Island will have any material adverse effect on its
operations. In some jurisdictions, the Company's pricing flexibility for
intra-state services may be limited because of regulation, although the
Company's direct competitors will be subject to similar restrictions. However,
there can be no assurance that future regulatory, judicial, or legislative
action will not have a material adverse effect on the Company.

     In arbitrating interconnection agreements under the 1996 Act between ILECs
and their potential competitors, some state commissions have considered whether
fiber should be an unbundled network element. The New York


                                       45
<PAGE>

Public Service Commission determined that it would not require NYNEX
Corporation to provide fiber as an unbundled network element. State commissions
in Florida, Maryland, North Carolina, and Virginia have either refused to
require the ILECs to offer fiber to competitors, or have stated that the issue
would be addressed at a later time. On the other hand, state commissions in
Illinois, Massachusetts, Arizona, Georgia, Minnesota, Ohio, Oregon and
Tennessee have found fiber to be a network element and required the ILECs to
offer it on an unbundled basis to CLECs. There can be no assurance that these
requirements, and the associated pricing methodologies, where applicable will
not reduce the demand for fiber provided by the Company.

     The Company has determined that there are advantages to having certain of
its subsidiaries subject to state regulation in Connecticut and New York. As a
regulated carrier in those two jurisdictions, these subsidiaries will have
access to poles and rights of way for its fiber lines that would not be
available to it as an unregulated lessor of fiber. Two subsidiaries of the
Company have, therefore, recently filed petitions in those two states
requesting authority to provide telecommunications services. The Company
anticipates that based on past practices these petitions will be granted within
the next three or four months. As a result, these subsidiaries will incur
certain costs to comply with regulatory requirements such as the filing of
tariffs, submission of periodic financial and operational reports to
regulators, and payment of regulatory fees and assessments in Connecticut and
New York.


     Local
     In addition to federal and state laws, local governments exercise legal
authority that may impact the Company's business. For example, local
governments, such as the City of Boston and the City of New York, typically
retain the ability to license public rights-of-way, subject to the limitation
that local governments may not prohibit persons from providing
telecommunications services. Local authorities affect the timing and costs
associated with the Company's use of public rights-of-way. These regulations
may have an adverse effect on the Company's business.


Employees

     As of April 30, 1998, the Company employed 11 people. The Company's
employees are not represented by any labor union. The Company considers its
relationship with employees to be satisfactory.

 Vice President, Operations

- ------------
(1) During 1997, while serving as Chairman and Chief Executive Officer of the
    Company, Mr. Crabtree was President of MaineCom Services, Inc., a
    wholly-owned subsidiary of CMP, which paid his salary and benefits.


                                       48
<PAGE>

  Therefore, the Company did not pay any compensation to Mr. Crabtree for his
  services in 1997; however, the Company reimbursed CMP $      for Mr.
  Crabtree's services in 1997. In May 1998, Mr. Crabtree became a full-time
  employee of the Company with an annual base salary of $200,000 and the Board
  of Directors of the Company granted to him an option to purchase up to
  shares of the Company's Common Stock, which becomes exercisable in four
  equal annual installments, beginning one year after the closing of the
  Offerings. The exercise price per share is the price to the public of a
  share of Common Stock in the Equity Offering. In addition, Mr. Crabtree is
  eligible to receive an annual bonus of up to 35% of his salary. Upon the
  closing of the Offerings, the Company will pay a cash bonus of $500,000 to
  MaineCom Services, Inc. in recognition of Mr. Crabtree's efforts on behalf
  of the Company while he was employed by MaineCom.

(2) In May 1998, the Board of Directors of the Company increased Mr.
    Colantonio's annual base salary to $200,000 and granted to him an option
    to purchase up to       shares of the Company's Common Stock, which
    becomes exercisable in four equal annual installments, with the first such
    installment becoming exercisable upon the closing of the Offerings. The
    exercise price per share is the price to the public of a share of Common
    Stock in the Equity Offering. In addition, Mr. Colantonio is also eligible
    to receive an annual bonus of up to 35% of his salary. Upon the closing of
    the Offerings, Mr. Colantonio will be entitled to a cash bonus of
    $500,000. Pursuant to the terms of Mr. Colantonio's employment agreement
    with the Company, MaineCom transferred       shares of Common Stock of the
    Company to Mr. Colantonio as of April 17, 1998. Mr. Colantonio may forfeit
    such shares if he voluntarily terminates employment with the Company prior
    to October 14, 2000. See "--Employment Agreements."


     Employment Agreements
     The Company has entered into an Employment Agreement with Victor
Colantonio, dated October 15, 1997, as amended. This Agreement has an initial
term of three years and automatically extends for one year terms thereafter
unless either party gives written notice of its desire to terminate the
agreement no later than the immediately preceding April 1. The Agreement
provides for an annual base salary of not less than $200,000. If Mr.
Colantonio's employment is terminated without cause after the occurrence of a
"Change of Control" (as defined in the Agreement) of the Company, Mr.
Colantonio will be entitled to receive a lump sum payment in an amount equal to
2.99 times his then current base salary.

     The Company has also entered into employment agreements with James Mack,
the Company's Vice President, Sales, and Michael Musen, the Company's Vice
President of Operations, dated May 4, 1998 and September 29, 1994,
respectively. The Company's agreement with Mr. Mack has a term of three years
and provides that Mr. Mack will receive a base salary of at least $150,000 per
year and bonus, awards, cash incentives and stock option incentives having a
value of at least an additional $150,000 per year provided certain performance
targets are met. Pursuant to the terms of this agreement, Mr. Mack was granted
an option to purchase up to       shares of the Company's Common Stock, which
become exercisable in four equal annual installments beginning one year after
the closing of the Offerings. The exercise price per share is the price to the
public of a share of Common Stock in the Equity Offering. The Company's
agreement with Mr. Musen has a term of three years and renews automatically on
an annual basis unless terminated by either party on at least 180 days' notice.
The Agreement provides for an annual base salary of $112,000.


     Option Grants
     The Company did not grant any options to the Named Executive Officers in
1997.


     Option Exercises and Options Outstanding
     None of the Named Executive Officers held any options as of December 31,
1997.


1998 Stock Incentive Plan

     The Company's 1998 Stock Incentive Plan (the "1998 Plan") was adopted by
the Board of Directors on May 18, 1998 and is expected to be approved by the
Company's stockholders on May 26, 1998. The 1998 Plan provides for the grant of
incentive stock options intended to qualify under Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"), nonstatutory stock options,
restricted stock awards and other stock-based awards, including the grant of
shares based upon certain conditions, the grant of securities convertible into
Common Stock and the grant of stock appreciation rights (collectively
"Awards"). Options may be granted at an exercise price which


                                       49
<PAGE>

may be less than, equal to or greater than the fair market value of the Common
Stock on the date of grant. Under present law, however, incentive stock options
and options intended to qualify as performance-based compensation under Section
162(m) of the Code may not be granted at an exercise price less than the fair
market value of the Common Stock on the date of grant (or less than 110% of the
fair market value in the case of incentive stock options granted to optionees
holding more than 10% of the voting power of the Company). Options granted
under the 1998 Plan typically will vest over time, subject to acceleration upon
a Change in Control. Restricted stock awards entitle recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all
or part of such shares from the recipient in the event that the conditions
specified in the applicable Award are not satisfied prior to the end of the
applicable restriction period established for such Award. Under the 1998 Plan,
the Board has the right to grant other Awards based upon the Common Stock
having such terms and conditions as the Board may determine, including the
grant of shares based upon certain conditions, the grant of securities
convertible into Common Stock and the grant of stock appreciation rights.
Officers, employees, directors, consultants and advisors of the Company and its
subsidiaries are eligible to be granted Awards under the 1998 Plan.

     The 1998 Plan is administered by the Board of Directors. The Board has the
authority to adopt, amend and repeal the administrative rules, guidelines and
practices relating to the 1998 Plan and to interpret the provisions of the 1998
Plan. The Board has authorized the Compensation Committee to administer certain
aspects of the 1998 Plan, including the granting of options to executive
officers.

     As of May 20, 1998, a total of       shares were reserved for issuance
under the 1998 Plan, of which       shares were subject to options having a
weighted average exercise price per share of $        .


Compensation Committee Interlocks and Insider Participation

     During 1997, the Company had no compensation committee, and no officers,
other than Messrs. Crabtree and Colantonio, who were also members of the Board
of Directors, participated in deliberations of the Board of Directors
concerning executive officer compensation. No interlocking relationship exists
between any member of the Company's anticipated Compensation Committee and any
member of any other company's board of directors or compensation committee.

                             CERTAIN TRANSACTIONS

     The Company has entered into certain agreements with NU and CMP,
affiliates of which are major stockholders of the Company, relating to fiber
optic facilities and services upon which the NEON system depends. See
"Business--Right of Way Agreements." The Company believes that these agreements
are on terms at least as favorable to the Company as could have been obtained
from unaffiliated third parties. NU has waived right of way fees otherwise
payable by the Company through 2004 in return for the Company's agreement to
build the NEON system to certain NU facilities and to allow NU to use 12 fibers
on designated route segments in the NU service territory.

     In     , 1998, the Company entered into a Restructuring and Contribution
Agreement with, inter alia, CMP, MaineCom (an affiliate of CMP) and Mode 1 (an
affiliate of NU) relating to the restructuring of the Company. Pursuant to this
Agreement, each of MaineCom and Mode 1 exchanged membership interests in
subsidiaries of the Company for shares of the Series B Convertible Preferred
Stock of the Company. See "Business --Reorganization."

     During the years ended December 31, 1996 and 1997, the Company reimbursed
CMP and/or MaineCom for personnel and construction costs related to activities
of the Company. The amount paid to CMP totaled $________ and $________ for the
years ended December 31, 1996 and 1997, respectively. Approximately $0 and
$29,779 was included in accounts payable at December 31, 1996 and 1997,
respectively.

     CMP and the Company are parties to a Tax Sharing Agreement pursuant to
which CMP has included the Company in its consolidated federal income tax
return since 1996. At December 31, 1996 and 1997, the amounts due under the Tax
Sharing Agreement to the Company from CMP amounted to approximately $0 and
$368,734, respectively, for current and deferred income tax benefits related to
CMP's utilization of the Company's loss carryforwards. As a result of this
arrangement, the Company has no loss carryforwards.

     The Company paid NU $________ in 1996 and $________ in 1997 for materials,
labor and other contractor charges related to the construction of the NEON
system. Approximately $357,100 and $494,500 was included in accounts payable at
December 31, 1996 and 1997, respectively.

     CMP agreed to allow right-of-way payments otherwise payable by the Company
to accrue so long as amounts borrowed by the Company from Peoples' Heritage
Bank under a $1.6 million construction loan agreement were outstanding. The
Company expects to repay the Peoples' Heritage Bank loan with the proceeds of
the Offerings. The amount of right-of-way payments accrued through March 31,
1998 was approximately $115,000.

     For a description of certain employment agreements and other arrangements
between the Company and its executive officers, see "Management--Executive
Compensation."

     Upon the closing of the Offerings, the Company has agreed to pay a bonus
of $500,000 to each of Mr. Colantonio and MaineCom Services, Inc. The payment
to MaineCom Services, Inc. is in recognition of the services provided by Mr.
Crabtree, as an employee of MaineCom, to the Company.

     In October 1997, the Company entered into a Construction Loan Agreement
with CMP, as amended in February 1998 and June 1998 (as amended, the "CMP Loan
Agreement"). Pursuant to the terms of the CMP Loan Agreement, the Company may
borrow up to $30 million to pay approved expenses related to the construction
of the NEON system. Amounts borrowed by the Company bear interest at an annual
interest rate equal to LIBOR plus 3%, and are secured by a first priority
security interest in all of the Company's assets, including the Company's
rights in the NEON system, except that part of the NEON system which is located
in CMP's service territory, as to which CMP's security interest is subordinated
to that of another lender. As of April 30, 1998, the Company had outstanding
principal of approximately $     million under the CMP Loan Agreement. Amounts
due under the CMP Loan Agreement are being paid in full with the proceeds of
the Offerings. See "Use of Proceeds."

     Concurrently with the CMP Loan Agreement, CMP was issued warrants to
purchase 5,876 shares of membership interest in FiveCom LLC with an exercise
price of $.01 per share.

                         DESCRIPTION OF CAPITAL STOCK

     As of April 30, 1998 (after giving effect to the Reorganization and the
Preferred Stock Conversion), there were outstanding an aggregate of
shares of Common Stock held of record by 22 stockholders.


Common Stock

     The Company's Restated Certificate of Incorporation authorizes the
issuance of up to 30,000,000 shares of Common Stock, $.01 par value per share.
Holders of Common Stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Accordingly, holders of a majority of the shares of Common Stock
entitled to vote in any election of directors may elect all of the directors
standing for election. Holders of Common Stock are entitled to receive ratably
such dividends, if any, as may be declared by the Board of Directors out of
funds legally available therefor, subject to any preferential dividend rights
of outstanding Preferred Stock. Upon the liquidation, dissolution or winding up
of the Company, the holders of Common Stock are entitled to receive ratably the
net assets of the Company available after the payment of all debts and other
liabilities and subject to the prior rights of any outstanding Preferred Stock.
Holders of Common Stock have no preemptive, subscription, redemption or
conversion rights. The outstanding shares of Common Stock are, and the shares
offered by the Company in the Equity Offering will be, when issued and paid
for, fully paid and nonassessable. The rights, preferences and privileges of
holders of Common Stock are subject to, and may be adversely affected by, the
rights of the holders of shares of any series of Preferred Stock which the
Company may designate and issue in the future.


Preferred Stock

     The Restated Certificate of Incorporation authorizes the issuance of up to
2,000,000 shares of Preferred Stock, $.01 par value per share. Under the terms
of the Restated Certificate of Incorporation, the Board of Directors is
authorized, subject to any limitations prescribed by law, without stockholder
approval, to issue such shares of Preferred Stock in one or more series. Each
such series of Preferred Stock shall have such rights, preferences, privileges
and restrictions, including voting rights, dividend rights, conversion rights,
redemption privileges and liquidation preferences, as shall be determined by
the Board of Directors.

     The purpose of authorizing the Board of Directors to issue Preferred Stock
and determine its rights and preferences is to eliminate delays associated with
a stockholder vote on specific issuances. The issuance of Preferred Stock,
while providing desirable flexibility in connection with possible acquisitions
and other corporate purposes, could have the effect of making it more difficult
for a third party to acquire, or of discouraging a third party from acquiring,
a majority of the outstanding voting stock of the Company. The Company has no
present plans to issue any shares of Preferred Stock.


Delaware Law and Certain Charter and Bylaw Provisions

     The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. Section 203 prohibits a publicly-held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the business
combination is approved in a prescribed manner. A "business combination"
includes mergers, asset sales and other transactions resulting in a financial
benefit to the interested stockholder. Subject to certain exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, 15% or more of the
corporation's voting stock.

     Under the Restated Certificate of Incorporation, any vacancy on the Board
of Directors, however occurring, including a vacancy resulting from an
enlargement of the Board, may only be filled by vote of a majority of the
directors then in office. The Restated Certificate of Incorporation also
provides that any action required or permitted to be taken by the stockholders
of the Company at an annual meeting or special meeting of stockholders may only
be taken if it is properly brought before such meeting and may not be taken by
written action in lieu of a meeting. The Restated Certificate of Incorporation
further provides that special meetings of the stockholders may only be called
by a Chairman of the Board of Directors or by the Board of Directors. Under the
Company's Bylaws, in order for any matter to be considered "properly brought"
before a meeting, a stockholder must comply with certain requirements regarding
advance notice to the Company. The foregoing provisions could have the effect
of delaying until the next stockholders meeting stockholder actions which are
favored by the holders of a majority of the


                                       56
<PAGE>

outstanding voting securities of the Company. These provisions may also
discourage another person or entity from making a tender offer for the
Company's Common Stock, because such person or entity, even if it acquired a
majority of the outstanding voting securities of the Company, would be able to
take action as a stockholder (such as electing new directors or approving a
merger) only at a duly called stockholders meeting, and not by written consent.
 

     The Restated Certificate of Incorporation contains certain provisions
permitted under the General Corporation Law of Delaware relating to the
liability of directors. The provisions eliminate a director's liability for
monetary damages for a breach of fiduciary duty, except in certain
circumstances involving wrongful acts, such as the breach of a director's duty
of loyalty or acts or omissions which involve intentional misconduct or a
knowing violation of law. Further, the Restated Certificate of Incorporation
contains provisions to indemnify the Company's directors and officers to the
fullest extent permitted by the General Corporation Law of Delaware. The
Company believes that these provisions will assist the Company in attracting
and retaining qualified individuals to serve as directors.


Transfer Agent and Registrar

     The transfer agent and registrar for the Company's Common Stock is
BankBoston, N.A.


Shareholders Agreement

     Central Maine Power Company and Northeast Utilities have entered into an
agreement dated May   , 1998, whereby each such party agrees that, following
the completion of the Offerings, it will not permit or cause the Company to (i)
merge or consolidate, liquidate or dissolve, change its form of organization or
sell, lease, exchange or transfer all or substantially all of its assets; or
(ii) seek bankruptcy protection or certain other protection from creditors,
without the consent of both parties. In addition, each of NU and CMP has rights
of first offer in connection with the proposed sale of Common Stock of the
Company held by the other party and the option to purchase the shares of Common
Stock of the Company held by the other party if such other party seeks
bankruptcy protection or similar relief. After the closing of the Offerings,
this agreement will remain in effect for so long as (a) NU owns at least 10% of
the outstanding Common Stock of the Company, fully diluted and (b) the
aggregate Common Stock of the Company owned by NU and CMP is at least 331/3% of
the outstanding Common Stock of the Company, fully diluted.

                    [E] DESCRIPTION OF CERTAIN INDEBTEDNESS

     Concurrently with the Equity Offering, the Company is offering its    %
Senior Discount Notes due 2008 pursuant to the Debt Offering for gross proceeds
of $    million. The following is a summary of certain terms of the Notes and
is qualified in its entirety by reference to the Indenture (the "Indenture")
relating to the Notes. A copy of the proposed form of Indenture has been filed
with the Registration Statement of which this Prospectus forms a part.

     The Notes will be unsecured senior obligations of the Company, and will

      of each year, commencing      , 2004.

     Except as described below, the Notes will not be redeemable prior to
     , 2003. Thereafter, the Notes will be redeemable at the option of the
Company, in whole or in part, at any time or from time to time. In the event
the Company consummates certain public equity offerings prior to      , 2001,
the Company may, at its option, use proceeds from such offerings to redeem up
to 35% of the original principal amount of the Notes.

     Upon the occurrence of a Change of Control (as defined in the Indenture),
each holder of Notes will have the right to require the Company to purchase all
or a portion of such holder's Notes at a price equal to 101% of the accreted
value thereof, together with accrued and unpaid interest to the date of

<PAGE>

                         [D] DESCRIPTION OF THE NOTES


General

     The Notes are to be issued under an Indenture, to be dated as of      ,
1998 (the "Indenture"), between the Company and      , as Trustee (the
"Trustee"). A copy of the form of the Indenture is filed as an exhibit to the
Registration Statement of which this Prospectus is a part. The following
summary of certain provisions of the Indenture does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all the
provisions of the Indenture, including the definitions of certain terms therein
and those terms made a part thereof by the Trust Indenture Act of 1939, as
amended. For purposes of this summary, the term "Company" refers only to
NorthEast Optic Network, Inc., and not to any of its subsidiaries.

     The Notes will be issued only in fully registered form, without coupons,
in denominations of $1,000 and any integral multiple of $1,000. No service
charge shall be made for any registration of transfer or exchange of Notes, but
the Company may require payment of a sum sufficient to cover any transfer tax
or other similar governmental charge payable in connection therewith.


Terms of the Notes

     The Notes will be unsecured senior obligations of the Company, limited to
$    million aggregate principal amount at maturity, and will mature on      ,
2008. No cash interest will accrue on the Notes prior to      , 2003, although
for U.S. Federal income tax purposes a significant amount of OID will be
recognized by a Holder as such discount accrues. See "Certain United States
Federal Income Tax Consequences" for a discussion regarding the taxation of
such OID. Cash interest will accrue on the Notes at the rate per annum shown on
the cover page hereof from      , 2003, or from the most recent date to which
interest has been paid or provided for, payable semiannually to Holders of
record at the close of business on the    or    immediately preceding the
interest payment date on    and    of each year, commencing    , 2004. The
Company will pay interest on overdue principal at 1% per annum in excess of
such rate, and it will pay interest on overdue installments of interest at such
higher rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.


Optional Redemption

     Except as set forth in the following paragraph, the Notes will not be
redeemable at the option of the Company prior to      , 2003. Thereafter, the
Notes will be redeemable, at the Company's option, in whole or in part, at any
time or from time to time, upon not less than 30 nor more than 60 days' prior
notice mailed by first-class mail to each Holder's registered address, at the
following redemption prices (expressed in percentages of Accreted Value), plus
accrued and unpaid interest to the redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date), if redeemed during the 12-month period
commencing on    of the years set forth below:


<TABLE>

       2006 and thereafter .........       100
</TABLE>

     In addition, at any time and from time to time prior to      , 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Notes with the proceeds of one or more Public Equity Offerings, at a
redemption price (expressed as a percentage of Accreted Value) of   % plus
accrued and unpaid interest to the redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date); provided, however, that (i) at least $
aggregate principal amount of the Notes must remain outstanding and be held,
directly or indirectly, by Persons other than the Company and its Affiliates,
after each such redemption and (ii) any such redemption shall occur within 60
days of the applicable Public Equity Offering.


                                       59
<PAGE>

     In the case of any partial redemption, selection of the Notes for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Note of $1,000 in principal amount or less shall be
redeemed in part. If any Note is to be redeemed in part only, the notice of
redemption relating to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation of the original Note.


Ranking

     The indebtedness evidenced by the Notes will be senior unsecured
obligations of the Company, will rank pari passu in right of payment with all
existing and future senior indebtedness of the Company and will be senior in
right of payments to all future subordinated indebtedness of the Company. As of
March 31, 1998, after giving effect to the issuance of the Notes and the
application of the proceeds therefrom, the Company's senior indebtedness
outstanding would have been approximately $   million, including the Notes.

     A portion of the operations of the Company are conducted through its
subsidiaries. Claims of creditors of such subsidiaries, including trade
creditors, secured creditors and creditors holding indebtedness and guarantees
issued by such subsidiaries, and claims of preferred stockholders (if any) of
such subsidiaries generally will have priority with respect to the assets and
earnings of such subsidiaries over the claims of creditors of the Company,
including holders of the Notes. The Notes, therefore, will be effectively
subordinated to creditors (including trade creditors) and preferred
stockholders (if any) of subsidiaries of the Company. At March 31, 1998 on a
pro forma basis after giving effect to the Offering and the application of the
net proceeds therefrom, the total liabilities of the Company's subsidiaries
were approximately $   million, including trade payables. Although the
Indenture limits the incurrence of Indebtedness and preferred stock of certain
of the Company's subsidiaries, such limitation is subject to a number of
significant qualifications. Moreover, the Indenture does not impose any
limitation on the incurrence by such subsidiaries of liabilities that are not
considered Indebtedness or Preferred Stock under the Indenture. See "--Certain
Covenants--Limitation on Indebtedness."


Book-Entry, Delivery and Form

     The Notes sold will be issued in the form of a Global Note. The Global
Note will be deposited with, or on behalf of, the Depository and registered in
the name of the Depository or its nominee. Except as set forth below, the
Global Note may be transferred, in whole and not in part, only to the
Depository or another nominee of the Depository. Investors may hold their
beneficial interests in the Global Note directly through the Depository if they
have an account with the Depository or indirectly through organizations which
have accounts with the Depository.

     Upon the transfer of a Note in definitive form, such Note will, unless the
Global Note has previously been exchanged for Notes in definitive form, be
exchanged for an interest in the Global Note representing the principal amount
of Notes being transferred.

     The Depository has advised the Company as follows: The Depository is a
limited-purpose trust company and organized under the laws of the State of New
York, a member of the Federal Reserve System, a "clearing corporation" within
the meaning of the New York Uniform Commercial Code, and "a clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. The
Depository was created to hold securities of institutions that have accounts
with the Depository ("participants") and to facilitate the clearance and
settlement of securities transactions among its participants in such securities
through electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. The
Depository's participants include securities brokers and dealers (which may
include the Initial Purchasers), banks, trust companies, clearing corporations
and certain other organizations. Access to the Depository's book-entry system
is also available to others such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship with a participant,
whether directly or indirectly.

     Upon the issuance of the Global Note, the Depository will credit, on its
book-entry registration and transfer system, the principal amount of the Notes
represented by such Global Note to the accounts of participants. Ownership of
beneficial interests in the Global Note will be limited to participants or
persons that may hold interests through participants. Ownership of beneficial
interests in the Global Note will be shown on, and the transfer of those
ownership interests will be effected only through, records maintained by the
Depository (with respect to


                                       60
<PAGE>

participants' interest) and such participants (with respect to the owners of
beneficial interests in the Global Note other than participants). The laws of
some jurisdictions may require that certain purchasers of securities take
physical delivery of such securities in definitive form. Such limits and laws
may impair the ability to transfer or pledge beneficial interests in the Global
Note.

     So long as the Depository, or its nominee, is the registered holder and
owner of the Global Note, the Depository or such nominee, as the case may be,
will be considered the sole legal owner and holder of the related Notes for all
purposes of such Notes and the Indenture. Except as set forth below, owners of
beneficial interests in the Global Note will not be entitled to have the Notes
represented by the Global Note registered in their names, will not receive or
be entitled to receive physical delivery of certificated Notes in definitive
form and will not be considered to be the owners or holders of any Notes under
the Global Note. The Company understands that under existing industry practice,
in the event an owner of a beneficial interest in the Global Note desires to
take any action that the Depository, as the holder of the Global Note, is
entitled to take, the Depository would authorize the participants to take such
action, and that the participants would authorize beneficial owners owning
through such participants to take such action or would otherwise act upon the
instructions of beneficial owners owning through them.

     Payment of principal of and interest on Notes represented by the Global
Note registered in the name of and held by the Depository or its nominee will
be made to the Depository or its nominee, as the case may be, as the registered
owner and holder of the Global Note.

     The Company expects that the Depository or its nominee, upon receipt of
any payment of principal of or interest on the Global Note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Note as
shown on the records of the Depository or its nominee. The Company also expects
that payments by participants to owners of beneficial interests in the Global
Note held through such participants will be governed by standing instructions
and customary practices and will be the responsibility of such participants.
The Company will not have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests in the Global Note for any Note or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests or for
any other aspect of the relationship between the Depository and its
participants or the relationship between such participants and the owners of
beneficial interests in the Global Note owning through such participants.

     Unless and until it is exchanged in whole or in part for certificated
Notes in definitive form, the Global Note may not be transferred except as a
whole by the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository.

     Although the Depository has agreed to the foregoing procedures in order to
facilitate transfers of interests in the Global Note among participants of the
Depository, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time. Neither the
Trustee nor the Company will have any responsibility for the performance by the
Depository or its participants or indirect participants of their respective
obligations under the rules and procedures governing their operations.


Certificated Notes

     The Notes represented by the Global Note are exchangeable for certificated
Notes in definitive form of like tenor as such Notes in denominations of U.S.
$1,000 and integral multiples thereof if (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for the Global
Note or if at any time the Depository ceases to be a clearing agency registered
under the Exchange Act and a successor Depository is not appointed by the
Company within 90 days, (ii) the Company in its discretion at any time
determines not to have all of the Notes represented by the Global Note or (iii)
an Event of Default has occurred and is continuing. Any Note that is
exchangeable pursuant to the preceding sentence is exchangeable for
certificated Notes issuable in authorized denominations and registered in such
names as the Depository shall direct. Subject to the foregoing, the Global Note
is not exchangeable, except for a Global Note of the same aggregate
denomination to be registered in the name of the Depository or its nominee.


                                       61

Same-Day Payment

     The Indenture will require that payments in respect of Notes (including
principal, premium and interest) be made by wire transfer of immediately
available funds to the accounts specified by the holders thereof or, if no such
account is specified, by mailing a check to each such holder's registered
address.


Change of Control

     Upon the occurrence of any of the following events (each a "Change of
Control"), each Holder shall have the right to require that the Company
repurchase such Holder's Notes at a purchase price in cash equal to 101% of the
Accreted Value thereof on the date of purchase, plus accrued and unpaid
interest, if any, to the date of purchase (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date):

     (i) any "person" (as such term is used in Sections 13(d) and 14(d) of the
   Exchange Act), other than one or more Permitted Holders, is or becomes the
   beneficial owner (as defined in Rules 13d-3 and 3d-5 under the Exchange
   Act, except that for purposes of this clause (i) such person shall be
   deemed to have "beneficial ownership" of all shares that any such person
   has the right to acquire, whether such right is exercisable immediately or
   only after the passage of time), directly or indirectly, of more than 35%
   of the total voting power of the Voting Stock of the Company; provided,
   however, that the Permitted Holders beneficially own (as defined in Rules
   13d-3 and 13d-5 under the Exchange Act), directly or indirectly, in the
   aggregate a lesser percentage of the total voting power of the Voting Stock
   of the Company than such other person and do not have the right or ability
   by voting power, contract or otherwise to elect or designate for election a
   majority of the Board of Directors (for the purposes of this clause (i),
   such other person shall be deemed to beneficially own any Voting Stock of a
   specified corporation held by another Person (a "parent corporation") if
   such other person is the beneficial owner (as described in this clause
   (i)), directly or indirectly, of more than 35% of the voting power of the
   Voting Stock of such parent corporation and the Permitted Holders
   beneficially own (as described in this clause (i)), directly or indirectly,
   in the aggregate a lesser percentage of the voting power of the Voting
   Stock of such parent corporation and do not have the right or ability by
   voting power, contract or otherwise to elect or designate for election a
   majority of the board of directors of such parent corporation);

     (ii) individuals who on the Issue Date constituted the Board of Directors
   (together with any new directors whose election by such Board of Directors
   or whose nomination for election by the shareholders of the Company was
   approved by a vote of 662/3% of the directors of the Company then still in
   office who were either directors on the Issue Date or whose election or
   nomination for election was previously so approved) cease for any reason to
   constitute a majority of the Board of Directors then in office;

     (iii) the adoption of a plan relating to the liquidation or dissolution
     of the Company; or

     (iv) the merger or consolidation of the Company with or into another
   Person or the merger of another Person with or into the Company, or the
   sale of all or substantially all the assets of the Company to another
   Person (other than a Person that is controlled by the Permitted Holders),
   and, in the case of any such merger or consolidation, the securities of the
   Company that are outstanding immediately prior to such transaction and
   which represent 100% of the aggregate voting power of the Voting Stock of
   the Company are changed into or exchanged for cash, securities or property,
   unless pursuant to such transaction such securities are changed into or
   exchanged for, in addition to any other consideration, securities of the
   surviving corporation that represent immediately after such transaction, at
   least a majority of the aggregate voting power of the Voting Stock of the
   surviving corporation.

     Within 30 days following any Change of Control, the Company shall mail a
notice to each Holder with a copy to the Trustee (the "Change of Control
Offer") stating: (1) that a Change of Control has occurred and that such Holder
has the right to require the Company to purchase such Holder's Notes at a
purchase price in cash equal to 101% of the Accreted Value thereof on the date
of purchase, plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of holders of record on the relevant record date to
receive interest on the relevant interest payment date); (2) the circumstances
and relevant facts regarding such Change of Control (including information with
respect to pro forma historical income, cash flow and capitalization after
giving effect to such Change of Control); (3) the repurchase date (which shall
be no earlier than 30 days nor later than 60 days from


                                       62
<PAGE>

the date such notice is mailed); and (4) the instructions determined by the
Company, consistent with the covenant described hereunder, that a Holder must
follow in order to have its Notes purchased.

     If a Holder's Notes are redeemed by the Company pursuant to its option to
redeem Notes as described under "--Optional Redemption" prior to the date on
which the Company would be obligated to pay for such Notes tendered pursuant to
a Change of Control Offer, such Holder will be entitled to receive only the
redemption price. The Company will not be required to make a Change of Control
Offer following a Change of Control if a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in the Indenture applicable to a Change of Control Offer
made by the Company and purchases all Notes validly tendered and not withdrawn
under such Change of Control Offer.

     The Company shall comply, to the extent applicable, with the requirements
of Section 14(e) of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of Notes pursuant to this
covenant described hereunder. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of the covenant
described hereunder, the Company shall comply with the applicable securities
laws and regulations and shall not be deemed to have breached its obligations
under the covenant described hereunder by virtue thereof.

     The Change of Control purchase feature is a result of negotiations between
the Company and the Underwriters. Management has no present intention to engage
in a transaction involving a Change of Control, although it is possible that
the Company would decide to do so in the future. Subject to the limitations
discussed below, the Company could, in the future, enter into certain
transactions, including acquisitions, refinancings or other recapitalizations,
that would not constitute a Change of Control under the Indenture, but that
could increase the amount of indebtedness outstanding at such time or otherwise
affect the Company's capital structure or credit ratings. Restrictions on the
ability of the Company to incur additional Indebtedness are contained in the
covenants described under "--Certain Covenants--Limitation on Indebtedness",
"--Limitation on Liens" and "--Limitation on Sale/Leaseback Transactions." Such
restrictions can only be waived with the consent of the holders of a majority
in principal amount of the Notes then outstanding. Except for the limitations
contained in such covenants, however, the Indenture will not contain any
covenants or provisions that may afford holders of the Notes protection in the
event of a highly leveraged transaction.

     Future indebtedness of the Company may contain prohibitions on the
occurrence of certain events that would constitute a Change of Control or
require such indebtedness to be repurchased upon a Change of Control. Moreover,
the exercise by the holders of their right to require the Company to repurchase
the Notes could cause a default under such indebtedness, even if the Change of
Control itself does not, due to the financial effect of such repurchase on the
Company. Finally, the Company's ability to pay cash to the holders of Notes
following the occurrence of a Change of Control may be limited by the Company's
then existing financial resources. There can be no assurance that sufficient
funds will be available when necessary to make any required repurchases. The
provisions under the Indenture relative to the Company's obligation to make an
offer to repurchase the Notes as a result of a Change of Control may be waived
or modified with the written consent of the holders of a majority in principal
amount of the Notes.


     Certain Covenants

     The Indenture contains covenants including, among others, the following:

     Limitation on Indebtedness. (a) The Company shall not, and shall not
permit any Restricted Subsidiary to, Incur, directly or indirectly, any
Indebtedness; provided, however, that the Company may Incur Indebtedness if, on
the date of such Incurrence and after giving effect thereto, the Consolidated
Leverage Ratio would be less than 5.5 to 1.0 if such Indebtedness is Incurred
on or prior to December 31, 2000 or 5.0 to 1.0 if such Indebtedness is Incurred
thereafter.

     (b) Notwithstanding the foregoing paragraph (a), the Company and the
Restricted Subsidiaries may Incur any or all of the following Indebtedness:

   (1) Indebtedness Incurred pursuant to Credit Agreements; provided, however,
       that, after giving effect to any such Incurrence, the aggregate principal
       amount of such Indebtedness then outstanding does not exceed $25 million
       less the sum of all principal payments with respect to such Indebtedness
       pursuant to paragraph (a)(ii)(A) of the covenant described under
       "--Limitation on Sales of Assets and Subsidiary Stock";


                                       63
<PAGE>

   (2) Indebtedness owed to and held by the Company or a Restricted Subsidiary;
       provided, however, that (i) any subsequent issuance or transfer of any
       Capital Stock of a Restricted Subsidiary which results in any such
       Indebtedness being owned or held by a Person that is no longer a
       Restricted Subsidiary or any subsequent transfer of such Indebtedness
       (other than to the Company or a Restricted Subsidiary) shall be deemed,
       in each case, to constitute the Incurrence of such Indebtedness by the
       obligor thereon and (ii) if the Company is the obligor on such
       Indebtedness, such Indebtedness is expressly subordinated to the prior
       payment in full in cash of all obligations with respect to the Notes;

   (3) the Notes;

   (4) Indebtedness outstanding on the Issue Date (other than Indebtedness
       described in clause (1), (2) or (3) of this covenant);

   (5) Refinancing Indebtedness in respect of Indebtedness Incurred pursuant to
       paragraph (a) or pursuant to clause (3) or (4) above, this clause (5) or
       clauses (7), (8) or (10) below; provided, however, that to the extent
       such Refinancing Indebtedness directly or indirectly Refinances
       Indebtedness of a Restricted Subsidiary described in clause (10), such
       Refinancing Indebtedness shall be Incurred only by such Restricted
       Subsidiary;

   (6) Hedging Obligations directly related to Indebtedness permitted to be
       Incurred by the Company or any Restricted Subsidiary pursuant to
       paragraphs (a) or (b) hereof;

   (7) Indebtedness (including Indebtedness of a Restricted Subsidiary Incurred
       and outstanding on or prior to the date on which such Subsidiary was
       acquired by the Company or another Restricted Subsidiary) Incurred to
       finance the cost (including the cost of design, development, acquisition,
       construction, installation, improvement, transportation and integration)
       of acquiring property, plant and equipment or inventory to be used in
       connection with a Telecommunications Business (including acquisitions by
       way of capital lease and acquisitions of the Capital Stock of a Person
       that becomes a Restricted Subsidiary to the extent of the fair market
       value of the property, plant and equipment or inventory so acquired) by
       the Company or Restricted Subsidiary after the Issue Date for use in a
       Related Business;

   (8) Indebtedness of the Company in an amount which, when taken together with
       the amount of Indebtedness Incurred pursuant to this clause (8) and then
       outstanding, does not exceed two times the Net Cash Proceeds received by
       the Company after the Issue Date as a capital contribution from, or from
       the issuance and sale of its Capital Stock (other than Disqualified
       Stock) to, a Person that is not a Subsidiary of the Company, to the
       extent such Net Cash Proceeds have not been used pursuant to paragraph
       (a)(3)(B) or paragraph (b)(i) of the covenant described under
       "--Limitation on Restricted Payments" to make a Restricted Payment;
       provided, however, that such Indebtedness does not mature prior to the
       Stated Maturity of the Notes and has an Average Life longer than the
       Average Life of the Notes;

   (9) Guarantees by any Restricted Subsidiary of the Notes, Indebtedness
       Incurred pursuant to paragraph (a) above and any Indebtedness that
       Refinances the Notes or any Indebtedness Incurred pursuant to paragraph
       (a) above;

  (10) Indebtedness of a Restricted Subsidiary Incurred and outstanding on or
       prior to the date on which such Subsidiary was acquired by the Company
       (other than Indebtedness Incurred in connection with, or to provide all
       or any portion of the funds or credit support utilized to consummate, the
       transaction or series of related transactions pursuant to which such
       Subsidiary became a Subsidiary or was acquired by the Company); provided,
       however, that on the date of such acquisition and after giving effect
       thereto, the Company would have been able to Incur at least $1.00 of
       additional Indebtedness pursuant to paragraph (a) hereof; and


  (11) Indebtedness Incurred in an aggregate amount which, when taken together
       with the aggregate amount of all other Indebtedness of the Company and
       its Restricted Subsidiaries outstanding on the date of such Incurrence
       (other than Indebtedness permitted by clause (1) through (10) above or
       paragraph (a)) does not exceed $5 million.


     (c) Notwithstanding the foregoing, the Company shall not Incur any
Indebtedness pursuant to the foregoing paragraph (b) if the proceeds thereof
are used, directly or indirectly, to Refinance any Subordinated Obligations


                                       64
<PAGE>

unless such Indebtedness shall be subordinated to the Notes to at least the
same extent as such Subordinated Obligations.

     (d) For purposes of determining compliance with the foregoing covenant,
(i) in the event that an item of Indebtedness meets the criteria of more than
one of the types of Indebtedness described above, the Company, in its sole
discretion, will classify such item of Indebtedness and only be required to
include the amount and type of such Indebtedness in one of the above clauses
and (ii) an item of Indebtedness may be divided and classified in more than one
of the types of Indebtedness described above. For the purposes of determining
the amount of Indebtedness outstanding at any time, Guarantees with respect to
Indebtedness otherwise included in the determination of such amount shall not
be included.

     Limitation on Restricted Payments. (a) The Company shall not, and shall
not permit any Restricted Subsidiary, directly or indirectly, to make a
Restricted Payment if at the time the Company or such Restricted Subsidiary
makes such Restricted Payment: (1) a Default shall have occurred and be
continuing (or would result therefrom); (2) the Company is not able to Incur an
additional $1.00 of Indebtedness pursuant to paragraph (a) of the covenant
described under "--Limitation on Indebtedness"; or (3) the aggregate amount of
such Restricted Payment and all other Restricted Payments since the Issue Date
would exceed the sum of (without duplication):

   (A) the remainder of (x) cumulative EBITDA during the period (taken as a
       single accounting period) beginning on the first day of the fiscal
       quarter of the Company beginning after the Issue Date and ending on the
       last day of the most recent fiscal quarter for which financial
       statements have been made publicly available but in no event ending more
       than 135 days prior to the date of such determination minus (y) the
       product of 1.5 times cumulative Consolidated Interest Expense during
       such period;

   (B) the aggregate Net Cash Proceeds received by the Company from the
       issuance or sale of its Capital Stock (other than Disqualified Stock)
       subsequent to the Issue Date (other than an issuance or sale to a
       Subsidiary of the Company and other than an issuance or sale to an
       employee stock ownership plan or to a trust established by the Company
       or any of its Subsidiaries for the benefit of their employees);

   (C) the amount by which Indebtedness of the Company is reduced on the
       Company's balance sheet upon the conversion or exchange (other than by a
       Subsidiary of the Company) subsequent to the Issue Date of any
       Indebtedness of the Company convertible or exchangeable for Capital
       Stock (other than Disqualified Stock) of the Company (less the amount of
       any cash, or the fair value of any other property, distributed by the
       Company upon such conversion or exchange); and

   (D) an amount equal to the sum of (i) the net reduction in Investments in
       Unrestricted Subsidiaries resulting from dividends, repayments of loans
       or advances or other transfers of assets, in each case to the Company or
       any Restricted Subsidiary from Unrestricted Subsidiaries, and (ii) the
       portion (proportionate to the Company's equity interest in such
       Subsidiary) of the fair market value of the net assets of an
       Unrestricted Subsidiary at the time such Unrestricted Subsidiary is
       designated a Restricted Subsidiary; provided, however, that the
       foregoing sum shall not exceed, in the case of any Unrestricted
       Subsidiary, the amount of Investments previously made (and treated as a
       Restricted Payment) by the Company or any Restricted Subsidiary in such
       Unrestricted Subsidiary.

   (b) The provisions of the foregoing paragraph (a) shall not prohibit:

     (i) any Restricted Payment (other than a Restricted Payment described in
   clause (i) of the definition of "Restricted Payment") made out of the Net
   Cash Proceeds of the substantially concurrent sale of, or made by exchange
   for, Capital Stock of the Company (other than Disqualified Stock and other
   than Capital Stock issued or sold to a Subsidiary of the Company or an
   employee stock ownership plan or to a trust established by the Company or
   any of its Subsidiaries for the benefit of their employees); provided,
   however, that (A) such Restricted Payment shall be excluded in the
   calculation of the amount of Restricted Payments and (B) the Net Cash
   Proceeds from such sale used to make such Restricted Payment shall be
   excluded from the calculation of amounts under clause (3)(B) of paragraph
   (a) above;

     (ii) any purchase, repurchase, redemption, defeasance or other
   acquisition or retirement for value of Subordinated Obligations made by
   exchange for, or out of the proceeds of the substantially concurrent sale
   of, Indebtedness of the Company which is permitted to be Incurred pursuant
   to the covenant described under "--Limitation on Indebtedness"; provided,
   however, that such purchase, repurchase, redemption, defeasance


                                       65
<PAGE>

   or other acquisition or retirement for value shall be excluded in the
   calculation of the amount of Restricted Payments;

     (iii) dividends paid within 60 days after the date of declaration thereof
   if at such date of declaration such dividend would have complied with this
   covenant; provided, however, that at the time of payment of such dividend,
   no other Default shall have occurred and be continuing (or result
   therefrom); provided further, however, that such dividend shall be included
   in the calculation of the amount of Restricted Payments; or

     (iv) the repurchase or other acquisition of shares of, or options to
   purchase shares of, common stock of the Company or any of its Subsidiaries
   from employees, former employees, directors or former directors of the
   Company or any of its Subsidiaries (or permitted transferees of such
   employees, former employees, directors or former directors), pursuant to
   the terms of the agreements (including employment agreements) or plans (or
   amendments thereto) approved by the Board of Directors under which such
   individuals purchase or sell or are granted the option to purchase or sell,
   shares of such common stock; provided, however, that the aggregate amount
   of such repurchases and other acquisitions shall not exceed $500,000 in any
   calendar year; provided further, however, that such repurchases and other
   acquisitions shall be excluded in the calculation of the amount of
   Restricted Payments.

     Limitation on Restrictions on Distributions from Restricted
Subsidiaries. The Company shall not, and shall not permit any Restricted
Subsidiary to, create or otherwise cause or permit to exist or become effective
any consensual encumbrance or restriction on the ability of any Restricted
Subsidiary to (a) pay dividends or make any other distributions on its Capital
Stock to the Company or a Restricted Subsidiary or pay any Indebtedness owed to
the Company, (b) make any loans or advances to the Company or (c) transfer any
of its property or assets to the Company (the limitations described in (a), (b)
and (c) being called the "Subsidiary Distributions"), except:

     (i) any encumbrance or restriction pursuant to an agreement in effect at
     or entered into on the Issue Date;

     (ii) any encumbrance or restriction with respect to a Restricted
   Subsidiary pursuant to an agreement relating to any Indebtedness Incurred
   by such Restricted Subsidiary on or prior to the date on which such
   Restricted Subsidiary was acquired by the Company (other than Indebtedness
   Incurred as consideration in, or to provide all or any portion of the funds
   or credit support utilized to consummate, the transaction or series of
   related transactions pursuant to which such Restricted Subsidiary became a
   Restricted Subsidiary or was acquired by the Company) and outstanding on
   such date;

     (iii) any encumbrance or restriction pursuant to an agreement effecting a
   Refinancing of Indebtedness Incurred pursuant to an agreement referred to
   in clause (i) or (ii) of this covenant or this clause (iii) or contained in
   any amendment to an agreement referred to in clause (i) or (ii) of this
   covenant or this clause (iii); provided, however, that the encumbrances and
   restrictions with respect to such Restricted Subsidiary contained in any
   such refinancing agreement or amendment are no less favorable to the
   Noteholders than encumbrances and restrictions with respect to such
   Restricted Subsidiary contained in such predecessor agreements;

     (iv) any customary encumbrance or restriction applicable to a Restricted
   Subsidiary that is contained in an agreement or instrument governing or
   relating to Indebtedness Incurred pursuant to clause (b)(1) of the covenant
   described under "Limitation on Indebtedness"; provided, however, that such
   encumbrances and restrictions permit the distribution of funds to the
   Company in an amount sufficient for the Company to make the timely payment
   of interest, premium (if any) and principal (whether at stated maturity, by
   way of a sinking fund applicable thereto, by way of any mandatory
   redemption, defeasance, retirement or repurchase thereof, including upon
   the occurrence of designated events or circumstances or by virtue of
   acceleration upon an event of default, or by way of redemption or
   retirement at the option of the holder of the Indebtedness, including
   pursuant to offers to purchase) according to the terms of the Indenture and
   the Notes and other Indebtedness that is solely an obligation of the
   Company; provided further, however, that such agreement or instrument may
   nevertheless contain (A) customary net worth, leverage, invested capital
   and other financial covenants, customary covenants regarding the merger of
   or sale of all or any substantial part of the assets of the Company or any
   Restricted Subsidiary, customary restrictions on transactions with
   affiliates and customary subordination provisions governing Indebtedness
   owed to the Company or any Restricted Subsidiary and (B) a customary
   provision prohibiting such Restricted Subsidiary from making any Subsidiary
   Distributions upon the occurrence and during the continuance of any payment
   default under any such agreement or instrument (for purposes of this clause
   (iv), any determination as to what is customary shall be conclusively
   determined in


                                       66

   good faith by the Chief Financial Officer of the Company as certified to
   the Trustee at the time such agreement or instrument is entered into);

     (v) any such encumbrance or restriction consisting of customary non
   assignment provisions in leases governing leasehold interests to the extent
   such provisions restrict the transfer of the lease or the property leased
   thereunder;

     (vi) in the case of clause (c) above, restrictions contained in security
   agreements or mortgages securing Indebtedness of a Restricted Subsidiary to
   the extent such restrictions restrict the transfer of the property subject
   to such security agreements or mortgages; and

     (vii) any restriction with respect to a Restricted Subsidiary imposed
   pursuant to an agreement entered into for the sale or disposition of all or
   substantially all the Capital Stock or assets of such Restricted Subsidiary
   pending the closing of such sale or disposition.

     Limitation on Sales of Assets and Subsidiary Stock. (a) The Company shall
not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
consummate any Asset Disposition unless (i) the Company or such Restricted
Subsidiary receives consideration at the time of such Asset Disposition at
least equal to the fair market value (including as to the value of all non-cash
consideration), as determined in good faith by the Board of Directors, of the
shares and assets subject to such Asset Disposition and at least 75% of the
consideration thereof received by the Company or such Restricted Subsidiary is
in the form of cash or cash equivalents and (ii) an amount equal to 100% of the
Net Available Cash from such Asset Disposition is applied by the Company (or
such Restricted Subsidiary, as the case may be) (A) first, to the extent the
Company elects (or is required by the terms of any Indebtedness), to prepay,
repay, redeem or purchase Senior Indebtedness or Indebtedness (other than any
Disqualified Stock) of a Wholly Owned Subsidiary (in each case other than
Indebtedness owed to the Company or an Affiliate of the Company controlled
directly or indirectly by the Company) within one year from the later of the
date of such Asset Disposition or the receipt of such Net Available Cash; (B)
second, to the extent of the balance of such Net Available Cash after
application in accordance with clause (A), to the extent the Company elects, to
acquire Additional Assets within one year from the later of the date of such
Asset Disposition or the receipt of such Net Available Cash; and (C) third, to
the extent of the balance of such Net Available Cash after application in
accordance with clauses (A) and (B), to make an offer to the holders of the
Notes pursuant to and subject to the conditions contained in the Indenture;
provided, however, that in connection with any prepayment, repayment or
purchase of Indebtedness pursuant to clause (A) or (C) above, the Company or
such Restricted Subsidiary shall permanently retire such Indebtedness and shall
cause the related loan commitment (if any) to be permanently reduced in an
amount equal to the principal amount so prepaid, repaid or purchased.
Notwithstanding the foregoing provisions of this paragraph, the Company and the
Restricted Subsidiaries shall not be required to apply any Net Available Cash
in accordance with this paragraph except to the extent that the aggregate Net
Available Cash from all Asset Dispositions which are not applied in accordance
with this paragraph exceeds $5.0 million. Pending application of Net Available
Cash pursuant to this covenant, such Net Available Cash shall be invested in
Permitted Investments or used to reduce outstanding borrowings under revolving
credit facilities.

     For the purposes of clause (a)(i) above, the following are deemed to be
cash or cash equivalents: (x) the assumption of Indebtedness of the Company or
any Restricted Subsidiary and the release of the Company or such Restricted
Subsidiary from all liability on such Indebtedness in connection with such
Asset Disposition and (y) securities received by the Company or any Restricted
Subsidiary from the transferee that are promptly converted by the Company or
such Restricted Subsidiary into cash.

     (b) In the event of an Asset Disposition that requires the purchase of the
Notes pursuant to clause (a)(ii)(C) above, the Company will be required to
purchase Notes tendered pursuant to an offer by the Company for the Notes at a
purchase price of 100% of their Accreted Value plus accrued but unpaid interest
in accordance with the procedures (including prorating in the event of
oversubscription) set forth in the Indenture. The Company shall not be required
to make such an offer to purchase Notes pursuant to this covenant if the Net
Available Cash available therefor is less than $5 million (which lesser amount
shall be carried forward for purposes of determining whether such an offer is
required with respect to the Net Available Cash from any subsequent Asset
Disposition).

     (c) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the


                                       67
<PAGE>

Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under this clause by
virtue thereof.

     Limitation on Affiliate Transactions. (a) The Company shall not, and shall
not permit any Restricted Subsidiary to, enter into or permit to exist any
transaction (including the purchase, sale, lease or exchange of any property,
employee compensation arrangements or the rendering of any service) with any
Affiliate of the Company (an "Affiliate Transaction") unless the terms thereof
(1) are no less favorable to the Company or such Restricted Subsidiary than
those that could be obtained at the time of such transaction in arm's-length
dealings with a Person who is not such an Affiliate, (2) if such Affiliate
Transaction involves an amount in excess of $1.0 million, (i) are set forth in
writing and (ii) have been approved by a majority of the members of the Board
of Directors having no personal stake in such Affiliate Transaction and (3) if
such Affiliate Transaction involves as amount in excess of $5.0 million, have
been determined by nationally recognized investment banking firm to be fair,
from a financial standpoint, to the Company and its Restricted Subsidiaries.

     (b) The provisions of the foregoing paragraph (a) shall not prohibit (i)
any Restricted Payment permitted to be paid pursuant to the covenant described
under "--Limitation on Restricted Payments", (ii) any issuance of securities,
or other payments, awards or grants in cash, securities or otherwise pursuant
to, or the funding of, employment arrangements, stock options and stock
ownership plans approved by the Board of Directors, (iii) the grant of stock
options or similar rights to employees and directors of the Company pursuant to
plans approved by the Board of Directors, (iv) loans or advances to employees
in the ordinary course of business in accordance with the past practices of the
Company or its Restricted Subsidiaries, but in any event not to exceed $1.0
million in the aggregate outstanding at any one time, (v) the payment of
reasonable fees to directors of the Company and its Restricted Subsidiaries who
are not employees of the Company or its Restricted Subsidiaries, (vi) any
Affiliate Transaction between the Company and a Wholly Owned Subsidiary or
between Wholly Owned Subsidiaries and (vii) the issuance or sale of any Capital
Stock (other than Disqualified Stock) of the Company.

     Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries. The Company shall not sell or otherwise dispose of any Capital
Stock of a Restricted Subsidiary, and shall not permit any Restricted
Subsidiary, directly or indirectly, to issue or sell or otherwise dispose of
any of its Capital Stock except (i) to the Company or a Wholly Owned
Subsidiary, (ii) directors' qualifying shares, (iii) if, immediately after
giving effect to such issuance, sale or other disposition, neither the Company
nor any of its Subsidiaries own any Capital Stock of such Restricted Subsidiary
or (iv) if, immediately after giving effect to such issuance, sale or other
disposition, such Restricted Subsidiary would no longer constitute a Restricted
Subsidiary and any Investment in such Person remaining after giving effect
thereto would have been permitted to be made under the covenant described under
"--Limitation on Restricted Payments" if made on the date of such issuance,
sale or other disposition.

     Limitation on Liens. The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, Incur or permit to exist any
Lien of any nature whatsoever on any of its properties (including Capital Stock
of a Restricted Subsidiary), whether owned at the Issue Date or thereafter
acquired, other than Permitted Liens, without effectively providing that the
Notes shall be secured equally and ratably with (or prior to) the obligations
so secured for so long as such obligations are so secured.

     Limitation on Sale/Leaseback Transactions. The Company shall not, and
shall not permit any Restricted Subsidiary to, enter into any Sale/Leaseback
Transaction with respect to any property unless (i) the Company or such
Subsidiary would be entitled to (A) Incur Indebtedness in an amount equal to
the Attributable Debt with respect to such Sale/Leaseback Transaction pursuant
to the covenant described under "--Limitation on Indebtedness" and (B) create a
Lien on such property securing such Attributable Debt without equally and
ratably securing the Notes pursuant to the covenant described under
"--Limitation on Liens", (ii) the net proceeds received by the Company or any
Restricted Subsidiary in connection with such Sale/Leaseback Transaction are at
least equal to the fair value (as determined by the Board of Directors) of such
property and (iii) the Company applies the proceeds of such transaction in
compliance with the covenant described under "--Limitation on Sale of Assets
and Subsidiary Stock".

     Future Guarantors. The Company shall cause each Restricted Subsidiary that
Guarantees any Indebtedness of the Company (other than the Notes) pursuant to
clause (b)(9) of the covenant described under "--Limitation on Indebtedness" to
guarantee the Notes on substantially the same terms and conditions as such
Guarantee.

     Merger and Consolidation. The Company shall not consolidate with or merge
with or into, or convey, transfer or lease, in one transaction or a series of
transactions, all or substantially all its assets to, any Person, unless: (i)
the


                                       68
<PAGE>

resulting, surviving or transferee Person (the "Successor Company") shall be a
Person organized and existing under the laws of the United States of America,
any State thereof or the District of Columbia and the Successor Company (if not
the Company) shall expressly assume, by an indenture supplemental thereto,
executed and delivered to the Trustee, in form satisfactory to the Trustee, all
the obligations of the Company under the Notes and the Indenture; (ii)
immediately after giving effect to such transaction (and treating any
Indebtedness which becomes an obligation of the Successor Company or any
Subsidiary as a result of such transaction as having been Incurred by such
Successor Company or such Subsidiary at the time of such transaction), no
Default shall have occurred and be continuing; (iii) immediately after giving
effect to such transaction, the Successor Company's Consolidated Leverage Ratio
is not greater than the Company's Consolidated Leverage Ratio immediately prior
to such transaction; and (iv) the Company shall have delivered to the Trustee
an Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and such supplemental indenture (if any)
comply with the Indenture.

     The Successor Company shall be the successor to the Company and shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture, but the predecessor Company in the case of a
conveyance, transfer or lease shall not be released from the obligation to pay
the principal of and interest on the Notes.

     SEC Reports. Notwithstanding that the Company may not be subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company
shall file with the SEC and provide the Trustee and Noteholders with such
annual reports and such information, documents and other reports as are
specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S.
corporation subject to such Sections, such information, documents and other
reports to be so filed and provided at the times specified for the filing of
such information, documents and reports under such Sections.


     Defaults

     An Event of Default is defined in the Indenture as (i) a default in the
payment of interest on the Notes when due, continued for 30 days, (ii) a
default in the payment of principal of any Note when due at its Stated
Maturity, upon optional redemption, upon required repurchase, upon declaration
or otherwise, (iii) the failure by the Company to comply with its obligations
under "--Certain Covenants--Merger and Consolidation" above, (iv) the failure
by the Company to comply for 30 days after notice with any of its obligations
in the covenants described above under "--Change of Control" (other than a
failure to purchase Notes) or under "--Certain Covenants" under "--Limitation
on Indebtedness", "--Limitation on Restricted Payments", "--Limitation on
Restrictions on Distributions from Restricted Subsidiaries", "--Limitation on
Sales of Assets and Subsidiary Stock" (other than a failure to purchase Notes),
"--Limitation on Affiliate Transactions", "--Limitation on the Sale or Issuance
of Capital Stock of Restricted Subsidiaries", "--Limitation on Liens",
"--Limitation on Sale/Leaseback Transactions", "--Future Guarantors" or "--SEC
Reports", (v) the failure by the Company to comply for 60 days after notice
with its other agreements contained in the Indenture, (vi) Indebtedness of the
Company or any Significant Subsidiary is not paid within any applicable grace
period after final maturity or is accelerated by the holders thereof because of
a default and the total amount of such Indebtedness unpaid or accelerated
exceeds $5 million (the "cross acceleration provision"), (vii) certain events
of bankruptcy, insolvency or reorganization of the Company or a Significant
Subsidiary (the "bankruptcy provisions") or (viii) any judgment or decree for
the payment of money in excess of $5 million is entered against the Company or
a Significant Subsidiary, remains outstanding for a period of 60 days following
such judgment and is not discharged, waived or stayed within 10 days after
notice (the "judgment default provision"). However, a default under clauses
(iv), (v) and (viii) will not constitute an Event of Default until the Trustee
or the holders of 25% in principal amount of the outstanding Notes notify the
Company of the default and the Company does not cure such default within the
time specified after receipt of such notice.

     If an Event of Default occurs and is continuing, the Trustee or the
holders of at least 25% in principal amount of the outstanding Notes may
declare the Accreted Value of and accrued but unpaid interest on all the Notes
to be due and payable (collectively, the "Default Amount"). Upon such a
declaration, the Default Amount shall be due and payable immediately. If an
Event of Default relating to certain events of bankruptcy, insolvency or
reorganization of the Company occurs and is continuing, the Default Amount on
all the Notes will ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any holders of the
Notes. Under certain circumstances, the holders of a majority in principal
amount of outstanding Notes may rescind any such acceleration with respect to
the Notes and its consequences.


                                       69
<PAGE>

     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the holders of the Notes unless
such holders have offered to the Trustee reasonable indemnity or security
against any loss, liability or expense. Except to enforce the right to receive
payment of principal, premium (if any) or interest when due, no holder of a
Note may pursue any remedy with respect to the Indenture or the Notes unless
(i) such holder has previously given the Trustee notice that an Event of
Default is continuing, (ii) holders of at least 25% in principal amount of the
outstanding Notes have requested the Trustee to pursue the remedy, (iii) such
holders have offered the Trustee reasonable security or indemnity against any
loss, liability or expense, (iv) the Trustee has not complied with such request
within 60 days after the receipt thereof and the offer of security or indemnity
and (v) the holders of a majority in principal amount of the outstanding Notes
have not given the Trustee a direction inconsistent with such request within
such 60-day period. Subject to certain restrictions, the holders of a majority
in principal amount of the outstanding Notes are given the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or of exercising any trust or power conferred on the Trustee. The
Trustee, however, may refuse to follow any direction that conflicts with law or
the Indenture or that the Trustee determines is unduly prejudicial to the
rights of any other holder of a Note or that would involve the Trustee in
personal liability.


     The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each holder of the Notes notice
of the Default within 90 days after it occurs. Except in the case of a Default
in the payment of principal of or interest on any Note, the Trustee may
withhold notice if and so long as a committee of its trust officers determines
that withholding notice is not opposed to the interest of the holders of the
Notes. In addition, the Company is required to deliver to the Trustee, within
120 days after the end of each fiscal year, a certificate indicating whether
the signers thereof know of any Default that occurred during the previous year.
The Company also is required to deliver to the Trustee, within 30 days after
the occurrence thereof, written notice of any event which would constitute
certain Defaults, their status and what action the Company is taking or
proposes to take in respect thereof.


     Amendments and Waivers

     Subject to certain exceptions, the Indenture may be amended with the
consent of the holders of a majority in principal amount of the Notes then
outstanding (including consents obtained in connection with a tender offer or
exchange for the Notes) and any past default or compliance with any provisions
may also be waived with the consent of the holders of a majority in principal
amount of the Notes then outstanding. However, without the consent of each
holder of an outstanding Note affected thereby, no amendment may, among other
things, (i) reduce the amount of Notes whose holders must consent to an
amendment, (ii) reduce the rate of or extend the time for payment of interest
on any Note, (iii) reduce the principal or Accreted Value of or extend the
Stated Maturity of any Note, (iv) reduce the amount payable upon the redemption
of any Note or change the time at which any Note may be redeemed as described
under "--Optional Redemption", (v) make any Note payable in money other than
that stated in the Note, (vi) impair the right of any holder of the Notes to
receive payment of principal of and interest on such holder's Notes on or after
the due dates therefor or to institute suit for the enforcement of any payment
on or with respect to such holder's Notes or (vii) make any change in the
amendment provisions which require each holder's consent or in the waiver
provisions.


     Without the consent of any holder of the Notes, the Company and Trustee
may amend the Indenture to cure any ambiguity, omission, defect or
inconsistency, to provide for the assumption by a successor corporation of the
obligations of the Company under the Indenture, to provide for uncertificated
Notes in addition to or in place of certificated Notes (provided that the
uncertificated Notes are issued in registered form for purposes of Section
163(f) of the Code, or in a manner such that the uncertificated Notes are
described in Section 163(f)(2)(B) of the Code), to add guarantees with respect
to the Notes, to secure the Notes, to add to the covenants of the Company for
the benefit of the holders of the Notes or to surrender any right or power
conferred upon the Company, to make any change that does not adversely affect
the rights of any holder of the Notes or to comply with any requirement of the
SEC in connection with the qualification of the Indenture under the Trust
Indenture Act.


     The consent of the holders of the Notes is not necessary under the
Indenture to approve the particular form of any proposed amendment. It is
sufficient if such consent approves the substance of the proposed amendment.


                                       70
<PAGE>

     After an amendment under the Indenture becomes effective, the Company is
required to mail to holders of the Notes a notice briefly describing such
amendment. However, the failure to give such notice to all holders of the
Notes, or any defect therein, will not impair or affect the validity of the
amendment.


     Transfer

     The Notes will be issued in registered form and will be transferable only
upon the surrender of the Notes being transferred for registration of transfer.
The Company may require payment of a sum sufficient to cover any tax,
assessment or other governmental charge payable in connection with certain
transfers and exchanges.


     Defeasance

     The Company at any time may terminate all its obligations under the Notes
and the Indenture ("legal defeasance"), except for certain obligations,
including those respecting the defeasance trust and obligations to register the
transfer or exchange of the Notes, to replace mutilated, destroyed, lost or
stolen Notes and to maintain a registrar and paying agent in respect of the
Notes. The Company at any time may terminate its obligations under "Change of
Control" and under the covenants described under "--Certain Covenants" (other
than the covenant described under "--Merger and Consolidation"), the operation
of the cross acceleration provision, the bankruptcy provisions with respect to
Significant Subsidiaries and the judgment default provision described under
"--Defaults" above and the limitations contained in clauses (iii) and (iv)
under "--Certain Covenants--Merger and Consolidation" above ("covenant
defeasance").

     The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because of
an Event of Default with respect thereto. If the Company exercises its covenant
defeasance option, payment of the Notes may not be accelerated because of an
Event of Default specified in clause (iv), (vi), (vii) (with respect only to
Significant Subsidiaries) or (viii) under "--Defaults" above or because of the
failure of the Company to comply with clause (iii) or (iv) under "--Certain
Covenants--Merger and Consolidation" above.

     In order to exercise either defeasance option, the Company must
irrevocably deposit in trust (the "defeasance trust") with the Trustee money or
U.S. Government Obligations for the payment of principal and interest on the
Notes to redemption or maturity, as the case may be, and must comply with
certain other conditions, including delivery to the Trustee of an Opinion of
Counsel to the effect that holders of the Notes will not recognize income, gain
or loss for Federal income tax purposes as a result of such deposit and
defeasance and will be subject to Federal income tax on the same amounts and in
the same manner and at the same times as would have been the case if such
deposit and defeasance had not occurred (and, in the case of legal defeasance
only, such Opinion of Counsel must be based on a ruling of the Internal Revenue
Service or other change in applicable Federal income tax law).


     Concerning the Trustee

          is to be the Trustee under the Indenture and has been appointed by
the Company as Registrar and Paying Agent with regard to the Notes.

     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
such claim as security or otherwise. The Trustee will be permitted to engage in
other transactions; provided, however, if it acquires any conflicting interest
it must either eliminate such conflict within 90 days, apply to the SEC for
permission to continue or resign.

     The Holders of a majority in principal amount of the outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that if an Event of Default occurs
(and is not cured), the Trustee will be required, in the exercise of its power,
to use the degree of care of a prudent man in the conduct of his own affairs.
Subject to such provisions, the Trustee will be under no obligation to exercise
any of its rights or powers under the Indenture at the request of any Holder of
Notes, unless such Holder shall have offered to the Trustee security and
indemnity satisfactory to it against any loss, liability or expense and then
only to the extent required by the terms of the Indenture.


                                       71
<PAGE>

 Governing Law

     The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflicts of law to the extent that the
application of the law of another jurisdiction would be required thereby.

     Certain Definitions

     "Accreted Value" means, as of any date (the "Specified Date"), the amount
provided below for each $1,000 principal amount of Notes:

     (i) if the Specified Date occurs on one of the following dates (each, a
   "Semi-Annual Accrual Date"), the Accreted Value will equal the amount set
   forth below for such Semi-Annual Accrual Date:

<TABLE>
<CAPTION>

</TABLE>                          

     (ii) if the Specified Date occurs between two Semi-Annual Accrual Dates,
   the Accreted Value will equal to the sum of (a) the Accreted Value for the
   Semi-Annual Accrual Date immediately preceding such Specified Date and (b)
   an amount equal to the product of (1) the Accreted Value for the
   immediately following Semi-Annual Accrual Date less the Accreted Value for
   the immediately preceding Semi-Annual Accrual Date multiplied by (2) a
   fraction, the numerator of which is the number of days elapsed from the
   immediately preceding Semi-Annual Accrual Date to the Specified Date, using
   a 360-day year of 12 30-day months, and the denominator of which is 180
   (or, if the Semi-Annual Accrual Date immediately preceding the Specified
   Date is the Issue Date, the denominator is the number of days from and
   including the Issue Date to and excluding the Specified Date; or

     (iii) if the Specified Date occurs after the last Semi-Annual Accrual
   Date, the Accreted Value will equal $1,000.

     "Additional Assets" means (i) any property or assets (other than
Indebtedness and Capital Stock) in a Related Business; (ii) the Capital Stock
of a Person that becomes a Restricted Subsidiary as a result of the acquisition
of such Capital Stock by the Company or another Restricted Subsidiary or (iii)
Capital Stock constituting a minority interest in any Person that at such time
is a Restricted Subsidiary; provided, however, that any such Restricted
Subsidiary described in clauses (ii) or (iii) above is primarily engaged in a
Related Business.

     "Affiliate" of any specified Person means any other Person, directly or
indirectly, controlling or controlled by or under direct or indirect common
control with such specified Person. For the purposes of this definition,
"control" when used with respect to any Person means the power to direct the
management and policies of such Person, directly or indirectly, whether through
the ownership of voting securities, by contract or otherwise; and the terms
"controlling" and "controlled" have meanings correlative to the foregoing. For
purposes of the provisions described under "--Certain Covenants--Limitation on
Restricted Payments", "--Certain Covenants--Limitation on Affiliate
Transactions" and "--Certain Covenants--Limitation on Sales of Assets and
Subsidiary Stock" only, "Affiliate" shall also mean any beneficial owner of
Capital Stock representing 5% or more of the total voting power of the Voting
Stock (on a fully diluted basis) of the Company or of rights or warrants to
purchase such Capital Stock (whether or not currently exercisable) and any
Person who would be an Affiliate of any such beneficial owner pursuant to the
first sentence hereof.

     "Asset Disposition" means any sale, lease, transfer or other disposition

                      [E] SHARES ELIGIBLE FOR FUTURE SALE

     Prior to the Equity Offering, there has been no market for the Common
Stock of the Company. Future sales of substantial amounts of Common Stock in
the public market could adversely affect prevailing market prices from time to
time. Furthermore, since only a limited number of shares will be available for
sale shortly after the Equity Offering because of certain contractual and legal
restrictions on resale (as described below), sales of substantial amounts of
Common Stock of the Company in the public market after the restrictions lapse
could adversely affect the prevailing market price and the ability of the
Company to raise equity capital in the future.

     Upon completion of the Equity Offering (based on shares outstanding at
April 30, 1998), the Company will have outstanding an aggregate of
shares of Common Stock, assuming no exercise of the Underwriters' over-allotment
option and no exercise of outstanding options. Of these shares, the
shares sold in the Equity Offering will be freely tradeable without
restrictions or further registration under the Securities Act, unless such
shares are purchased by an existing "affiliate" of the Company as that term is
defined in Rule 144 under the Securities Act (an "Affiliate"). The remaining
       shares of Common Stock held by existing stockholders are "restricted
securities" as that term is defined in Rule 144 under the Securities Act
("Restricted Shares"). Restricted Shares may be sold in the public market only
if registered or if they qualify for an exemption from registration under Rules
144, 144(k) or 701 promulgated under the Securities Act, which rules are
summarized below. As a result of the contractual restrictions described below
and the provisions of Rule 144, 144(k) and 701,        shares will be eligible
for sale upon expiration of the lock-up agreements on       , 180 days after
the date of this Prospectus and        shares will be eligible for sale upon
expiration of their respective one-year holding periods.

     All officers, directors and principal stockholders of the Company have
agreed not to 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, or otherwise transfer, lend or dispose
of, directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for 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 Common Stock for a period
of 180 days after the date of this Prospectus, without the prior written
consent of Credit Suisse First Boston Corporation, subject to certain limited
exceptions. Credit Suisse First Boston Corporation currently has no plans to
release any portion of the securities subject to lock-up agreements. When
determining whether or not to release shares from the lock-up agreements,
Credit Suisse First Boston Corporation will consider, among other factors, the
stockholder's reasons for requesting the release, the number of shares for
which the release is being requested and market conditions at the time.

     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an Affiliate) would be entitled to
sell within any three-month period a number of shares that does not exceed the
greater of (i) one percent of the number of shares of Common Stock then
outstanding (which will equal approximately        shares immediately after the
Equity Offering); or (ii) the average weekly trading volume of the Common Stock
on the Nasdaq National Market during the four calendar weeks preceding the
filing of a notice on Form 144 with respect to such sale. Sales under Rule 144
are also subject to certain manner of sale provisions, notice requirements and
the availability of current public information about the Company. Under Rule
144(k), a person who is not deemed to have been an Affiliate of the Company at
any time during the 90 days preceding a sale, and who has beneficially owned
the shares proposed to be sold for at least two years (including the holding
period of any prior owner except an Affiliate), is entitled to sell such shares
without complying with the manner of sale, public information, volume
limitation or notice provisions of Rule 144. Accordingly, unless otherwise
restricted, "144(k) shares" may therefore be sold immediately upon the
completion of the Equity Offering.

     Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 may be relied upon with respect to
the resale of securities originally purchased from the Company by its
employees, directors, officers, consultants or advisors prior to the date the
issuer becomes subject to the reporting requirements of the Securities Exchange
Act of 1934, as amended (the "Exchange Act") pursuant to written compensatory
benefit plans or written contracts relating to the compensation of such
persons. In addition, the SEC has indicated that Rule 701 will apply to typical
stock options granted by an issuer before it becomes subject to the reporting
requirements of the Exchange Act, along with the shares acquired upon exercise
of such options (including exercises after the date of the Equity Offering).
Securities issued in reliance on Rule 701 are restricted securities and,
subject to the


                                       82
<PAGE>

contractual restrictions described above, beginning 90 days after the date of
this Prospectus, may be sold (i) by persons other than Affiliates, subject only
to the manner of sale provisions of Rule 144 and (ii) by Affiliates, under Rule
144 without compliance with its one-year minimum holding period requirements.

     The Company has agreed not to 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, or otherwise transfer, lend or
dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock, or
enter into any swap or similar agreement that transfers, in whole or in part,
the economic risk of ownership of the Common Stock, for a period of 180 days
after the date of this Prospectus, without the prior written consent of Credit
Suisse First Boston Corporation, subject to certain limited exceptions.

     Following the Equity Offering, the Company intends to file registration
statements under the Securities Act covering approximately        shares of
Common Stock issued and outstanding, subject to outstanding options or reserved
for issuance under the Company's 1998 Plan. See "Management -- 1998 Stock
Incentive Plan." Accordingly, shares registered under such registration
statement will, subject to Rule 144 volume limitations applicable to
Affiliates, be available for sale in the open market, except to the extent that
such shares are subject to vesting restrictions with the Company or the
contractual restrictions described above.

               [E] CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
                         FOR NON-UNITED STATES HOLDERS


     The following is a summary of certain material United States federal
income tax considerations relating to the ownership and disposition of Common
Stock applicable to Non-United States Holders, but does not purport to be a
complete analysis of all the potential tax considerations relating thereto.
This summary is based on the provisions of the Internal Revenue Code of 1986,
as amended (the "Code"), the applicable Treasury Regulations promulgated or
proposed thereunder ("Treasury Regulations"), judicial authority and current
administrative rulings and practice, all of which are subject to change,
possibly on a retroactive basis. This summary does not address tax
considerations that may be relevant to a particular investor in light of such
investor's personal investment circumstances, nor does it address any tax
consequences arising out of the laws of any state, local or foreign taxing
jurisdiction.


     A "Non-United States Holder" is any beneficial owner of Common Stock that,
for United States federal income tax purposes, is a non-resident alien
individual, a foreign corporation, a foreign partnership or an estate or trust
not subject to United States federal income tax on a net income basis in
respect of income or gain with respect to Common Stock. An individual may be
deemed to be a resident alien (as opposed to a non-resident alien) by virtue of
being present in the United States on at least 31 days during the calendar year
and for an aggregate of 183 days during the calendar year and the two preceding
calendar years (counting, for such purposes, all the days present in the
current year, one-third of the days present in the immediately preceding year
and one-sixth of the days present in the second preceding year). In addition to
the "substantial presence test" described in the immediately preceding
sentence, an individual may be treated as a resident alien if he or she (i)
meets a lawful permanent residence test (a so-called "green card" test) or (ii)
elects to be treated as a U.S. resident and meets the "substantial presence
test" in the immediately following year.


Sale or Exchange of Common Stock

     A Non-United States Holder of Common Stock will generally not be subject
to United States federal income tax or withholding tax on any gain realized on
the sale or exchange of the Common Stock unless (1) the gain is effectively
connected with a United States trade or business of the Non-United States
Holder, (2) in the case of a Non-United States Holder who is an individual and
holds Common Stock as a capital asset, such Holder is present in the United
States for a period or periods aggregating 183 days or more during the taxable
year of the disposition and certain other conditions are met, (3) the Holder is
subject to tax pursuant to the provisions of the Code applicable to certain
United States expatriates, or (4) subject to the exceptions discussed below,
the Company is or has been a "United States real property holding corporation"
for federal income tax purposes at any time within the shorter of the five-year
period preceding such disposition or such Holder's holding period and certain
other conditions are met.


United States Real Property Holding Corporations

     Under present law, a company is a United States real property holding
corporation if (a) the fair market value of its United States real property
interests is more than (b) 50% of the sum of the fair market value of its
United States real property interests, its interests in real property located
outside the United States, and its other assets which are used or held in a
trade or business. Because of its investment in the communication network, the
Company may be a United States real property holding corporation. If the
Company is a "United States real property holding corporation," gain recognized
on a disposition of the Common Stock by a Non-United States Holder would be
subject to United States federal income tax unless (i) the Common Stock is
"regularly traded on an established securities market" within the meaning of
the Code and (ii) the Non-United States Holder disposing of Common Stock did
not own, actually or constructively, at any time during the five-year period
preceding the disposition, more than 5% of the Common Stock. It is anticipated
that the Common Stock will be regularly traded on an established securities
market.


Dividends

     Subject to the discussion below, any dividend paid to a Non-United States
Holder generally will be subject to United States withholding tax either at a
rate of 30% of the gross amount of the dividend or such lower rate as may be
specified by an applicable income tax treaty. For purposes of determining
whether tax is to be withheld


                                       84
<PAGE>

at a 30% rate or at a reduced rate as specified by an income tax treaty, the
Company ordinarily will presume that dividends paid to an address in a foreign
country are paid to a resident of such country absent knowledge that such
presumption is not warranted. Under recently issued Treasury Regulations,
however, Non-United States Holders of Common Stock who wish to claim the
benefit of an applicable treaty rate would be required to satisfy certain
certification requirements. The new Treasury Regulations are effective for
payments made after December 31, 1999. Dividends paid to a holder with an
address within the United States generally will not be subject to withholding
tax, unless the Company has actual knowledge that the holder is a Non-United
States Holder.

     Dividends received by a Non-United States Holder that are effectively
connected with a United States trade or business conducted by such Non-United
States Holder are exempt from withholding tax. However, such effectively
connected dividends are subject to regular United States income tax in the same
manner as if the Non-United States Holder were a United States resident. A
Non-United States Holder may claim exemption from withholding under the
effectively connected income exception by filing Form 4224 (Statement Claiming
Exemption from Withholding of Tax on Income Effectively Connected With the
Conduct of Business in the United States) each year with the Company or its
paying agent prior to the payment of the dividends for such year. Effectively
connected dividends received by a corporate Non-United States Holder may be
subject to an additional "branch profits tax" at a rate of 30% (or such lower
rate as may be specified by an applicable tax treaty) of such corporate
Non-United States Holder's effectively connected earnings and profits, subject
to certain adjustments.

     A Non-United States Holder eligible for a reduced rate of United States
withholding tax pursuant to a tax treaty may obtain a refund of any excess
amounts currently withheld by filing an appropriate claim for refund with the
United States Internal Revenue Service (the "IRS").


Backup Withholding and Information Reporting

     Generally, the Company must report to the IRS the amount of dividends
paid, the name and address of the recipient, and the amount, if any, of tax
withheld. A similar report is sent to the holder. Pursuant to tax treaties or
other agreements, the IRS may make its reports available to tax authorities in
the recipient's country of residence.

     Unless the Company has actual knowledge that a holder is a non-United
States person, dividends paid to a holder at an address within the United
States may be subject to backup withholding at a rate of 31% if the holder is
not an exempt recipient as defined in Treasury Regulation Section
1.6049-4(c)(1)(ii) (which includes corporations) and fails to provide a correct
taxpayer identification number and other information to the Company. If paid to
an address outside the United States, dividends on Common Stock held by a
Non-United States Holder will generally not be subject to the information
reporting and backup withholding requirements. However, under recently issued
Treasury Regulations, dividend payments will be subject to information
reporting and backup withholding unless applicable certification requirements
are satisfied. The new Treasury Regulations apply to dividend payments made
after December 31, 1999.

     If the proceeds of the disposition of Common Stock by a Non-United States
Holder are paid over, by or through a United States office of a broker, the
payment is subject to information reporting and to backup withholding at a rate
of 31% unless the disposing holder certifies as to its name, address and status
as a Non-United States Holder under penalties of perjury or otherwise
establishes an exemption. Generally, United States information reporting and
backup withholding will not apply to a payment of disposition proceeds if the
payment is made outside the United States through a non-United States office of
a non-United States broker. However, United States information reporting
requirements (but not backup withholding) will apply to a payment of
disposition proceeds outside the United States if (a) the payment is made
through an office outside the United States of a broker that is either (i) a
United States person for United States federal income tax purposes, (ii) a
"controlled foreign corporation" for United States federal income tax purposes,
or (iii) a foreign person which derives 50% or more of its gross income for
certain periods from the conduct of a United States trade or business, and (b)
the broker fails to maintain documentary evidence in its files that the holder
is a Non-United States Holder and that certain conditions are met or that the
holder otherwise is entitled to an exemption.

     Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to 31% backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained, provided that the required information is furnished to the IRS.

income tax considerations relating to the purchase, ownership and disposition
of the Notes, but does not purport to be a complete analysis of all the
potential tax considerations relating thereto. This summary is based on the
provisions of the Internal Revenue Code of 1986, as amended (the "Code"), the
applicable Treasury Regulations promulgated or proposed thereunder ("Treasury
Regulations"), judicial authority and current administrative rulings and
practice, all of which are subject to change, possibly on a retroactive basis.
This summary deals only with holders that will hold the Notes as "capital
assets" (within the meaning of Section 1221) and does not address tax
considerations that may be relevant to a particular investor in light of such
investor's personal investment circumstances, nor does the discussion address
special rules applicable to certain types of investors subject to special
treatment under the Code (including, without limitation, financial
institutions, broker-dealers, regulated investment companies, life insurance
companies, tax-exempt organizations, foreign corporations, non-resident aliens,
dealers in securities or currencies, persons that will hold Notes as a position
in a hedging transaction, "straddle" or "conversion transaction" for tax
purposes, or persons that have a "functional currency" other than the U.S.
dollar.) This summary discusses the tax considerations applicable to the
initial purchasers of the Notes who purchase the Notes at their "original issue
price" as defined in Section 1273 of the Code and does not discuss the tax
considerations applicable to subsequent purchasers of the Notes. The Company
has not sought any ruling from the Internal Revenue Service ("IRS") with
respect to the statements made and the conclusions reached in the following
summary, and there can been no assurance that the IRS will agree with such
statements and their conclusions. No consideration of any aspects of state,
local or foreign taxation is included herein. INVESTORS CONSIDERING THE
PURCHASE OF NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE
APPLICATION OF THE UNITED STATES FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR
SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE,
LOCAL OR FOREIGN TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.


UNITED STATES HOLDERS

     As used herein, the term "United States Holder" means the beneficial owner
of a Note that for United States federal income tax purposes is (i) a citizen
or resident of the United States, (ii) a corporation, partnership or other
entity created or organized in or under the laws of the United States or any
political subdivision thereof, (iii) an estate the income of which is subject
to United States federal income taxation regardless of its source, or (iv) a
trust if (a) a court within the United States is able to exercise primary
supervision over the administration of the trust and (b) one or more U.S.
persons have the authority to control all substantial decisions of the trust.


Stated Interest

     The receipt of cash in respect of the stated interest on the Notes will
not be taxable to the United States Holders but, rather, such stated interest
will be included in income as original issue discount ("OID") on a daily
economic accrual basis as described below.


Original Issue Discount

     General. Because the Notes are being issued with more than a de minimis
amount of discount from their stated redemption price at maturity and no
interest will be paid on the Notes prior to       , 2003, the Notes will be
considered to have been issued with OID for federal income tax purposes. The
OID on a Note will be the excess of its "stated redemption price at maturity"
(as defined below) over its "issue price." The stated redemption price at
maturity of a Note will be equal to the stated principal amount of the Note,
plus the amount of all stated interest due and payable on such Note. The issue
price of the Notes will be the first price to the public (excluding bond houses
and brokers) at which a substantial amount of the Notes were sold.

     A United States Holder will be required to include OID in gross income on
a daily economic accrual basis over the term of a Note, regardless of such
United States Holder's method of tax accounting and in advance of the receipt
of the cash attributable to such interest income. In general, a United States
Holder must include in income the sum of the daily portions of OID with respect
to a Note for each day during the taxable year on which the United States
Holder holds the Note, including the purchase date and excluding the
disposition date. The daily portion of OID is determined by allocating to each
day of any accrual period (which may be of any length and may vary


                                       86
<PAGE>

over the term of a Note, at the option of the holder, provided that each
accrual period is not longer than one year and each scheduled payment of
principal or interest on the Note occurs on the first or last day of an accrual
period) within a taxable year a pro rata portion of an amount equal to the
adjusted issue price of a Note at the beginning of the accrual period
multiplied by the yield to maturity of such Note. For purposes of computing
OID, the Company will use six-month accrual periods that end on the days in the
calendar year corresponding to the maturity date of the Notes and the date six
months prior to such maturity date, with the exception of an initial short
accrual period. The adjusted issue price of a Note at the beginning of any
accrual period is the issue price of the Note increased by the accrued OID for
all prior accrual periods (less any cash payments received on such Notes). The
yield to maturity of a Note is the discount rate that, when used in computing
the present value of all principal and interest payments to be made under a
Note, produces an amount equal to the issue price of the Note.

     Under these rules, United States Holders will have to include in gross
income increasingly greater amounts of OID in each successive accrual period.
Each payment made under a Note will be treated first as a payment of OID which
was previously includible in gross income (to the extent of OID that has
accrued as of the date of payment and has not been allocated to prior payments)
and second as a payment of principal (which generally is not includible in
income).

     Optional Redemption. The Company's option to redeem the Notes, in whole or
in part, at any time on or after       , 2003, at certain redemption prices
based on a percentage of Accreted Value, plus accrued interest will be treated
as a call option. See "Description of the Notes -- Optional Redemption."
Because any exercise by the Company of this option would not decrease the yield
on the Notes, the Company will not be presumed to exercise the option for
purposes of the OID rules.

     In addition to the optional redemption described above, the Company will
have the right to redeem up to 35% in aggregate face amount of the outstanding
Notes out of the net cash proceeds of one or more Public Equity Offerings on or
prior to          , 2000. See "Description of the Notes -- Optional
Redemption." Furthermore, a United States Holder will have the right to tender
Notes to the Company for redemption should the Company experience a Change of
Control. See "Description of the Notes -- Offer to Purchase upon Change of
Control." Such additional redemption rights should not affect, and will not be
treated by the Company as affecting, the determination of the yield or maturity
of the Notes.

     The tax treatment of a redemption of the Notes generally should be
governed by the rules for dispositions thereof as described below.

     If a United States Holder tenders Notes for redemption as a result of a
Change of Control, the United States Holder may be required to include as
ordinary income any amount the Holder is entitled to receive in excess of the
Accreted Value of a Note on the date of the redemption. Holders should consult
their own tax advisors regarding the treatment of payments received upon any
optional redemptions.


Disposition of the Notes

     Generally, upon the sale or exchange or redemption for a Note, a United
States Holder will realize taxable gain or loss equal to the difference between
the amount of cash or other property received by the United States Holder in
exchange for such Note (except to the extent such amount realized is
attributable to accrued but unpaid interest that such holder has not included
in gross income previously) and such holder's adjusted tax basis in such Note.
A United States holder's adjusted tax basis in a Note will initially equal the
cost of the Note to such holder and will be increased by any accrued OID
includible in such holder's gross income and decreased by the amount of any
payments received by such holder in respect of such Note regardless of whether
such payments are denominated as principal or interest. Any gain or loss upon a
sale or other disposition of a Note will generally be capital gain or loss. At
the time of sale or redemption, any such gain will be taxed to a United States
Holder who is a natural person at a maximum rate of 20 percent (10 percent, if
such holder is in a 15 percent bracket) if the Note is held for more than 18
months. If the United States Holder has held the Note more than 12 months but
not more than 18 months, any gain recognized on a sale of the Notes will be
taxed for federal income tax purposes at a maximum rate of 28 percent (15
percent if such older is in a 15 percent bracket).


                                       87

Information Reporting and Backup Withholding

     A United States Holder may be subject, under certain circumstances, to
backup withholding at a 31 percent rate with respect to payments received with
respect to the Notes. This withholding generally applies only if the U.S.
Holder (i) fails to furnish his social security or taxpayer identification
number ("TIN"), (ii) furnishes an incorrect TIN, (iii) is notified by the
Internal Revenue Service that he has failed to report properly payments of
interest and dividends and the service has notified the Company that he is
subject to withholding or (iv) fails under certain circumstances to provide a
certified statement, signed under penalty of perjury, that the TIN provided is
his correct number and that he is not subject to backup withholding. Any amount
withheld from a payment to a United States Holder under the backup withholding
rules is allowable as a credit against such holder's federal income tax
liability, provided that the required information is furnished to the Internal
Revenue Service. Certain holders (including, among others, corporations and
foreign individuals who comply with certain certification requirements
described below under "Non-United States Holders") are not subject to backup
withholding. United States Holders should consult their tax advisors as to
their qualification for exemption from backup withholding and the procedure for
obtaining such an exemption.

     The Company will furnish to the IRS and to record holders of the Notes (to
whom it is required to furnish such information) information relating to the
amount of interest and OID, as applicable.


THE COMPANY AND U.S. CORPORATE HOLDERS

     The Notes will constitute "applicable high yield discount obligations"
("AHYDOs") if the yield to maturity of the Notes will be equal to or greater
than the sum of the relevant applicable federal rate ("AFR") in effect for debt
instruments issued in      1998 (   % compounded semi-annually), plus 5
percentage points. If the Notes constitute AHYDOs, the Company will not be
entitled to deduct any interest on the Notes until it pays such interest in
cash or other property (other than stock or debt instruments of the Company or
related party). In addition, if the yield to maturity of the Notes exceeds the
sum of the relevant AFR plus six percentage points (the "Excess Yield"), the
"disqualified portion" of the OID accruing on the Notes will not be deductible
by the Company and to the extent of the Company's current and accumulated
earnings and profits will be treated as a dividend distribution solely for
purposes of the dividends received deduction of Sections 243, 246 and 246A of
the Code with respect to holders that are U.S. corporations. In general, the
"disqualified portion" of OID for any accrual period will be equal to that
portion of the OID attributable to the yield on the Note in excess of the AFR
plus six percentage points.

     Subject to otherwise applicable limitations, holders that are U.S.
corporations will be entitled to a dividends received deduction (generally at a
70% rate) with respect to the disqualified portion of the accrued OID if the
Company has sufficient current or accumulated "earnings and profits." The
excess will continue to be taxed as ordinary OID income in accordance with the
rules described above in "-- United States Holders -- Original Issue Discount."
 


NON-UNITED STATES HOLDERS

     As used herein, the term "Non-United States Holder" means any beneficial
owner of a Note or Common Stock that is not a United States Holder.

     The following discussion is a summary of certain U.S. federal income tax
consequences to a Non-United States Holder of a Note.

     Stated Interest and OID on Notes. Generally any interest or OID paid to a
Non-United States Holder of a Note will not be subject to U.S. federal income
or withholding tax, provided that (i) the holder is not (A) a direct or
indirect owner of 10% or more of the total voting power of all voting stock of
the Company or (B) a controlled foreign corporation related to the Company
through stock ownership, (ii) such interest payments are not effectively
connected with the conduct by the Non-United States Holder of a trade or
business within the United States and (iii) the Company (or its paying agent)
receives certain information from the holder certifying under penalties of
perjury that such holder is a Non-United States Holder.

     If these conditions are not satisfied a Non-United States Holder generally
would be subject to U.S. withholding tax at a flat rate of 30% (or lower
applicable treaty rate) on interest payments and payments (including redemption
proceeds) attributable to OID on the Notes.


                                       88
<PAGE>

Sale, Exchange or Redemption of the Notes

     Expect as provided below and subject to the discussion concerning backup
withholding, a Non-United States Holder of a Note will generally not be subject
to United States federal income tax or withholding tax on any gain realized on
the sale, exchange or redemption of the Note unless (1) the gain is effectively
connected with a United States trade or business of the Non-United States
Holder, (2) in the case of a Non-United States Holder who is an individual,
such Holder is present in the United States for a period or periods aggregating
183 days or more during the taxable year of the disposition and certain other
conditions are met or (3) the Holder is subject to tax pursuant to the
provisions of the Code applicable to certain United States expatriates.


     Information and Backup Withholding
     The Treasury regulations provide that backup withholding and information
reporting will not apply to payments of principal on the Notes by the Company
to a Non-U.S. Holder, if the holder certifies as to its non-U.S. status under
penalties of perjury or otherwise establishes an exemption (provided that
neither the Company nor their paying agents has actual knowledge that the
holder is a United States person or that the conditions of any other exemption
are not, in fact, satisfied).

     The payment of the proceeds from the disposition of the Notes to or
through the United States office of any broker, U.S. or foreign, will be
subject to information reporting and possibly backup withholding unless the
owner certifies as its non-U.S. status under penalty of perjury or otherwise
establishes an exemption, provided that the broker does not have actual
knowledge that the holder is a U.S. person or that the conditions of any other
exemption are not, in fact, satisfied. The payment of the proceeds from the
disposition of a Note to or through a non-U.S. office of a non-U.S. broker that
is not a U.S. related person will not be subject to information reporting or
backup withholding. For this purpose, a "U.S. related person" is (i) a
"controlled foreign corporation" for U.S. federal income tax purposes or (ii) a
foreign person 50% or more of whose gross income from all sources for the
three-year period ending with the close of its taxable year preceding the
payment (or for such part of the period that the broker has been in existence)
is derived from activities that are effectively connected with the conduct of a
United States trade or business.

     In the case of the payment of proceeds from the disposition of Notes to or
through a non-U.S. office of a broker that is either a U.S. person or a U.S.
related person, the regulations require information reporting on the payment
unless the broker has documentary evidence in its files that the owner is a
Non-U.S. Holder and the broker has no knowledge to the contrary. Backup
withholding will not apply to payments made through foreign offices of a broker
that is not a U.S. person or a U.S. related person (absent actual knowledge
that the payee is a U.S. person).

     The United States Department of the Treasury recently promulgated final
regulations regarding the information reporting and backup reporting rules
discussed above. In general, the final regulations do not significantly alter
the substantive information reporting and backup withholding requirements but
rather unify current certification procedures and forms and clarify reliance
standards. In addition, the final regulations permit the shifting of primary
responsibility for withholding to certain financial intermediaries acting on
behalf of beneficial owners. The final regulations are generally effective for
payments made after December 31, 1999, subject to certain transition rules.
Prospective purchasers of the Notes should consult their own tax advisors
concerning the effect of such regulations on their particular situations.

     Under the terms and subject to the conditions contained in the
Underwriting Agreement dated     , 1998 (the "Underwriting Agreement"), the
underwriters named below (the "Underwriters"), for whom Credit Suisse First
Boston Corporation and              are acting as representatives (the
"Representatives"), have severally but not jointly agreed to purchase from the
Company and the Selling Stockholders the following respective numbers of shares
of Common Stock:

                                                      ==========
</TABLE>

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will be obligated to purchase all of the shares of the Common
Stock offered hereby (other than those shares covered by the over-allotment
option described below) if any are purchased. The Underwriting Agreement
provides that, in the event of a default by an Underwriter, in certain
circumstances the purchase commitments of non-defaulting Underwriters may be
increased or the Underwriting Agreement may be terminated.

     The Company and the Selling Stockholders have granted to the Underwriters
an option expiring on the 30th day after the date of this Prospectus, to
purchase up to         additional shares from the Company and an aggregate of
        additional shares from the Selling Stockholders at the initial public
offering price, less the underwriting discounts and commissions, all as set
forth on the cover page of this Prospectus. Such option may be exercised only
to cover over-allotments in the sale of the shares of Common Stock. To the
extent such option is exercised, each Underwriter will become obligated,
subject to certain conditions, to purchase approximately the same percentage of
such additional shares of Common Stock as it was obligated to purchase pursuant
to the Underwriting Agreement.

     The Company and the Selling Stockholders have been advised by the
Representatives that the Underwriters propose to offer the shares of Common
Stock to the public initially at the price set forth on the cover page of this
Prospectus, and through the Representatives, to certain dealers (who may
include the Underwriters) at such price less a concession of $       per share
and the Underwriters and such dealers may allow a discount of $       per share
on sales to certain other dealers. After the initial public offering, the
public offering price and concession and discount to dealers may be changed by
the Representatives.

     Each of the Company and its officers, directors and principal stockholders
have agreed, subject to certain exceptions, that it will not offer, sell,
contract to sell, announce its intention to sell, pledge or otherwise dispose
of, directly or indirectly, or file with the Securities and Exchange Commission
a registration statement under the Securities Act of 1933 (the "Securities
Act") relating to, any shares of Common Stock or securities convertible into or
exchangeable or exercisable for Common Stock, without the prior written consent
of Credit Suisse First Boston Corporation for a period of 180 days after the
date of this Prospectus. See "Shares Eligible for Future Sale."

     The Underwriters have reserved for sale at the initial public offering
price up to         shares of the Common Stock for employees, directors and
certain other persons associated with the Company who have expressed an
interest in purchasing such shares of Common Stock in the offering. The number
of shares available for sale to the general public in the offering will be
reduced to the extent these individuals purchase such reserved shares. Any
reserved shares not so purchased will be offered by the Underwriters to the
general public on the same terms as the other shares offered hereby.

     The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments which the Underwriters may be
required to make in respect thereof.

     Application has been made to list the shares of Common Stock on the Nasdaq
National Market.

     Prior to the Equity Offering, there has been no public market for the
Common Stock of the Company. The initial public offering price will be
determined through negotiations between the Company and the Representatives.


                                       90
<PAGE>

Among the factors considered in determining the initial public offering price
will be prevailing market conditions for initial public offerings, certain
financial information of the Company, the history of, and the prospects for,
the Company and the industry in which it competes, and assessment of the
Company's management, its past and present operations, the prospects for, and
timing of, future revenues of the Company, the present state of the Company's
development, and the above factors in relation to market values and various
valuation measures of other companies engaged in activities similar to the
Company. There can be no assurance that an active trading market will develop
for the Common Stock or that the Common Stock will trade in the public market
subsequent to the Offering at or above the initial public offering price.

     The Representatives, on behalf of the Underwriters, may engage in
over-allotment, stabilizing transactions, syndicate covering transactions and
penalty bids. Over-allotment involves syndicate sales in excess of the offering
size, which creates a syndicate short position. Stabilizing transactions permit
bids to purchase the underlying security so long as the stabilizing bids do not
involve purchases of the securities in the open market after the distribution
has been completed in order to cover syndicate short positions. Penalty bids
permit the Representatives to reclaim a selling concession from a syndicate
member when the securities originally sold by such syndicate member are
purchased in a syndicate covering transaction to cover syndicate short
positions. Such stabilizing transactions, syndicate covering transactions and
penalty bids may cause the price of the securities to be higher than it would
otherwise be in the absence of such transactions. These transactions may be
effected on The Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

     The Underwriters do not intend to confirm sales of the Common Stock
offered hereby to any accounts over which they exercise discretionary
authority.

</TABLE>

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will be obligated to purchase all of the shares of the securities
offered hereby if any are purchased. The Underwriting Agreement provides that,
in the event of a default by an Underwriter, in certain circumstances the
purchase commitments of non-defaulting Underwriters may be increased or the
Underwriting Agreement may be terminated.

     The Company has been advised by the Underwriters that the Underwriters
propose to offer the Notes to the public initially at the price set forth on
the cover page of this Prospectus, and to certain dealers (who may include the
Underwriters) at such price less a concession of   % of the principal amount,
and the Underwriters and such dealers may allow a discount of   % of the
principal amount on sales to certain other dealers. After the initial public
offering, the public offering price and concession and discount to dealers may
be changed by the Underwriters.

     The Underwriters have informed the Company that they do not expect
discretionary sales by the Underwriters to exceed 5% of the principal amount
being offered hereby.

     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute
to payments which the Underwriters may be required to make in respect thereof.

     The Underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids. Over-allotment involves
syndicate sales in excess of the offering size, which creates a syndicate short
position. Stabilizing transactions permit bids to purchase the underlying
security so long as the stabilizing bids do not exceed a specified maximum.
Syndicate covering transactions involve purchases of the Notes in the open
market after the distribution has been completed in order to cover syndicate
short positions. Penalty bids permit the Underwriters to reclaim a selling
concession from a syndicate member when the Notes originally sold by such
syndicate member are purchased in a syndicate covering transaction to cover
syndicate short positions. Such stabilizing transactions, syndicate covering
transactions and penalty bids may cause the price of the Notes to be higher
than it would otherwise be in the absence of such transactions.

                        [D] NOTICE TO CANADIAN RESIDENTS


Resale Restrictions

     The distribution of the Notes in Canada is being made only on a private
placement basis exempt from the requirement that the Company prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of Notes are effected. Accordingly, any resale of the Notes in Canada
must be made in accordance with applicable securities laws, which will vary
depending on the relevant jurisdiction, and which may require resales to be
made in accordance with available statutory exemptions or pursuant to a
discretionary exemption granted by the applicable Canadian securities
regulatory authority. Purchasers are advised to seek legal advice prior to any
resale of the Notes.


Representations of Purchasers

     Each purchaser of the Notes in Canada who receives a purchase confirmation
will be deemed to represent to the Company and the dealer from whom such
purchase confirmation is received that (i) such purchaser is entitled under
applicable provincial securities laws to purchase such Notes without the
benefit of a prospectus qualified under such securities laws, (ii) where
required by law, that such purchaser is purchasing as principal and not as
agent, and (iii) such purchaser has reviewed the text above under "Resale
Restrictions".


Rights of Action (Ontario Purchasers)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.


Enforcement of Legal Rights

     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Canadian purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such persons
in Canada or to enforce a judgment obtained in Canadian courts against such
issuer or persons outside of Canada.


Notice to British Columbia Residents

     A purchaser of Notes to whom the Securities Act (British Columbia) applies
is advised that such purchaser is required to file with the British Columbia
Securities Commission a report within ten days of the sale of any Notes
acquired by such purchaser pursuant to this offering. Such report must be in
the form attached to British Columbia Securities Commission Blanket Order BOR
#95/17, a copy of which may be obtained from the Company. Only one such report
must be filed in respect of Notes acquired on the same date and under the same
prospectus exemption.


Taxation and Eligibility for Investment

     Canadian purchasers of Notes should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the Notes in
their particular circumstances and with respect to the eligibility of the Notes
for investment by the purchaser under relevant Canadian Legislation.

                        [E] NOTICE TO CANADIAN RESIDENTS


Resale Restrictions

     The distribution of the Common Stock in Canada is being made only on a
private placement basis exempt from the requirement that the Company and the
Selling Stockholders prepare and file a prospectus with the securities
regulatory authorities in each province where trades of Common Stock are
effected. Accordingly, any resale of the Common Stock in Canada must be made in
accordance with applicable securities laws, which will vary depending on the
relevant jurisdiction, and which may require resales to be made in accordance
with available statutory exemptions or pursuant to a discretionary exemption
granted by the applicable Canadian securities regulatory authority. Purchasers
are advised to seek legal advice prior to any resale of the Common Stock.


Representations of Purchasers

     Each purchaser of Common Stock in Canada who receives a purchase
confirmation will be deemed to represent to the Company, the Selling
Stockholders and the dealer from whom such purchase confirmation is received
that (i) such purchaser is entitled under applicable provincial securities laws
to purchase such Common Stock without the benefit of a prospectus qualified
under such securities laws, (ii) where required by law, that such purchaser is
purchasing as principal and not as agent, and (iii) such purchaser has reviewed
the text above under "Resale Restrictions".


Rights of Action (Ontario Purchasers)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.


Enforcement of Legal Rights

     All of the issuer's directors and officers as well as the experts named
herein and the Selling Shareholders may be located outside of Canada and, as a
result, it may not be possible for Canadian purchasers to effect service of
process within Canada upon the issuer or such persons. All or a substantial
portion of the assets of the issuer and such persons may be located outside of
Canada and, as a result, it may not be possible to satisfy a judgment against
the issuer or such persons in Canada or to enforce a judgment obtained in
Canadian courts against such issuer or persons outside of Canada.


Notice to British Columbia Residents

     A purchaser of Common Stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
Common Stock acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from the Company. Only one
such report must be filed in respect of Common Stock acquired on the same date
and under the same prospectus exemption.


Taxation and Eligibility for Investment

     Canadian purchasers of Common Stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the Common
Stock in their particular circumstances and with respect to the eligibility of
the Common Stock for investment by the purchaser under relevant Canadian
Legislation.

After the reorganization transaction discussed in Note 14 to NorthEast Optic
Network, Inc.'s consolidated financial statements is effected, we expect to be
in position to render the following audit report.



                                                             ARTHUR ANDERSEN LLP

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To NorthEast Optic Network, Inc.:

We have audited the accompanying consolidated balance sheets of NorthEast Optic
Network, Inc. (a Delaware corporation) and subsidiaries as of December 31, 1996
and 1997, and the related consolidated statements of operations, stockholders'
equity (deficit) and cash flows for each of the three years in the period ended
December 31, 1997. 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 generally accepted auditing
standards. 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 the 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of NorthEast Optic
Network, Inc. and subsidiaries as of December 31, 1996 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                (Including Data Applicable to Unaudited Periods)

(1) OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

     NorthEast Optic Network, Inc. (the Company) (formerly FiveCom, Inc.) and
its subsidiaries are engaged in the ownership, management, operation and
construction of fiber optic telecommunication networks in the Northeast,
consisting of New England and New York.

     The Company was incorporated in Massachusetts in July 1989. In May 1996,
FiveCom LLC, an operating subsidiary majority-owned by the Company, was
organized in Massachusetts. Also in May 1996, FiveCom LLC and Mode 1
Communications, Inc. (Mode 1), an affiliate of Northeast Utilities Services
Company (NU), organized NECOM LLC in Massachusetts, with FiveCom LLC owning
60%, and Mode 1 owning 40% of the membership interest in NECOM LLC. In December
1996, FiveCom LLC and Central Maine Power Company (CMP), organized FiveCom of
Maine LLC in Massachusetts, with CMP owning 66.67% and FiveCom LLC owning
33.33% of the membership interests in FiveCom of Maine LLC. The Company has
accounted for its ownership interest in these entities as consolidated entities
with minority interest due to its ownership/control in each of the
subsidiaries.

     To date, the Company has recorded limited revenues, principally from
contract and other services, and has incurred cumulative operating losses. The
Company is dependent on the funds received from CMP (Note 5) to fund
construction of the communications networks and working capital. The Company is
also dependent upon a single or limited source of suppliers for a number of
components and parts. Shortages resulting from a change in arrangements with
these suppliers and manufacturers could cause significant delays in the
expansion of the NEON systems and could have a material adverse effect on the
Company.

     The market for fiber optic telecommunications networks in which the
Company operates can be characterized as rapidly changing due to technological
advancements, the introduction of new products and services and the increasing
demands placed on equipment in worldwide telecommunications networks.

     The accompanying consolidated financial statements reflect the application
of certain accounting policies as described below and elsewhere in these notes
to consolidated financial statements.

 (a) Principles of Consolidation
     The consolidated financial statements include the accounts of NorthEast
Optic Network, Inc. and its majority owned or controlled subsidiaries, FiveCom
LLC, FiveCom of Maine LLC and NECOM LLC. All significant intercompany
transactions and balances have been eliminated in consolidation.

 (b) Minority Interest in Consolidated Subsidiaries
     Minority interest in the Company at December 31, 1996 and 1997 consists of
other members' interests in the LLCs identified above. Changes in minority
interest reflect other members' capital adjusted by their portion of the net
loss.

 (c) Interim Financial Statements (Unaudited)
     The accompanying consolidated financial statements as of March 31, 1998
and for the three-month periods ended March 31, 1997 and 1998 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, 1998 are not necessarily indicative of the results that may be expected for
the year ending December 31, 1998.

 (d) Management Estimates
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual amounts could differ from those estimates.

         (Including Data Applicable to Unaudited Periods)--(Continued)

(1) OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

 (e) Revenue Recognition
     Revenues on telecommunications network services are recognized ratably
over the term of the applicable agreements with customers. Other service
revenue, which consists of design and installation work, is recognized as
services are performed.

 (f) Income Taxes
     The Company has been majority-owned by CMP and under a tax-sharing
arrangement has been included in the consolidated federal tax return of CMP
since 1996 (see Note 2).

 (g) Cash and Cash Equivalents
     The Company accounts for investments under Statement of Financial
Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt
and Equity Securities. Under SFAS No. 115, investments for which the Company
has the positive intent and ability to hold to maturity, consisting of cash
equivalents, are reported at amortized cost, which approximates fair market
value. Cash equivalents are highly liquid investments with original maturities
of three months or less. To date, the Company has not recorded any realized
gains or losses. Cash and cash equivalents consist of the following:

</TABLE>

 (h) Deferred Revenue
     Deferred revenue represents prepayments received from customers for future
use of the Company's fiber optic network, as well as prepayment for
installation services that have not yet been provided. During 1997 and the
first quarter of 1998, the Company derived revenue from leasing dark fiber
optic cable. Lease payments are structured as either prepayments or monthly
recurring charges. Prepayments are accounted for as deferred revenue and
recognized over the term of the respective customer fiber optic lease
agreement. At December 31, 1996 and 1997, the Company had prepaid lease
payments totaling $225,000 and $1,144,170, respectively.

 (i) Depreciation
     The Company provides for depreciation using the straight-line method to
allocate the cost of property and equipment over their estimated useful lives
as follows:


<TABLE>
<S>                                    <C>
   Communications network ..........    20 years
   Machinery and equipment .........   5-7 years
   Motor vehicles ..................   3-5 years
   Furniture and fixtures ..........     7 years
</TABLE>

 (j) Long-Lived Assets
     The Company follows SFAS No. 121, Accounting for Long-Lived Assets and for
Long-Lived Assets To Be Disposed Of. SFAS No. 121, which requires that
long-lived assets be reviewed for impairment by comparing the fair value of the
assets with their carrying amount. Any write-downs are to be treated as
permanent reductions in the carrying amount of the assets. Accordingly, the
Company evaluates the possible impairment of long-lived assets at each
reporting period based on the undiscounted projected cash flows of the related
asset. Should there be an

(1) OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

impairment, the cash flow estimates that will be used will contain management's
best estimates, using appropriate and customary assumption and projections at
the time. To date the Company does not believe that an impairment exists.

 (k) Concentrations of Credit Risk
     Financial instruments that subject the Company to significant
concentrations of credit risk consist primarily of cash and cash equivalents
and accounts receivable. The Company's cash equivalents are invested in
financial instruments with high credit ratings. Concentration of credit risk
with respect to accounts receivable is limited to customers to whom the Company
makes significant sales. One customer accounted for approximately 90%, 90%, and
88% of accounts receivable at December 31, 1996 and 1997 and March 31, 1998,
respectively (see Note 12). To control credit risk, the Company performs
regular credit evaluations of its customers' financial condition and maintains
allowances, when required, for potential credit losses.

 (l) Fair Value of Financial Instruments
     The carrying amounts of the Company's cash and cash equivalents, accounts
receivable and accounts payable approximate fair value due to the short-term
nature of these instruments. The carrying amounts of debt issued pursuant to
agreements with banks approximate fair value as the interest rates on these
instruments fluctuate with market interest rates.

 (m) Earnings per Share
     The Company has adopted SFAS No. 128, Earnings per Share, effective
December 15, 1997. SFAS No. 128 establishes standards for computing and
presenting earnings per share and applies to entities with publicly held common
stock or potential common stock. The Company has applied the provisions of SFAS
No. 128, retroactively to all periods presented. In accordance with SEC Staff
Accounting Bulletin (SAB) No. 98, the Company has determined that there were no
nominal issuances of common stock or potential common stock in the period prior
to the Company's planned initial public offering. The dilutive effect of
potential common shares in 1998, consisting of outstanding stock options and
convertible preferred stock, is determined using the treasury method and the
if-converted method, respectively, in accordance with SFAS No. 128. Diluted
weighted average shares outstanding for 1995, 1996 and 1997 exclude the
potential common shares from warrants, stock options and convertible preferred
stock outstanding because to do so would have been antidilutive for the years
presented. The potential common shares excluded in 1995, 1996 and 1997 related
to outstanding warrants and stock options were 0, 0 and 4,493 shares,
respectively. The potential common shares excluded in 1995, 1996 and 1997
related to convertible preferred stock were 21,180, 391,332 and 1,096,953
shares, respectively. In addition, the warrants to purchase membership interest
in a subsidiary (see Note 7(d)) have been excluded from diluted weighted
average shares.

 (n) New Accounting Standards
     AICPA Statement of Position (SOP) 98-5, Reporting on the Costs of Start-Up
Activities was issued in April 1998. SOP 98-5 requires that all
non-governmental entities expense the costs of start-up activities, including
organizational costs, as those costs are incurred. The Company has recorded
such costs as expense, in the period incurred.

     In June 1997, the FASB issued SFAS No. 130, Reporting Comprehensive
Income. SFAS No. 130 requires disclosure of all components of comprehensive
income on an annual and interim basis. Comprehensive income is defined as the
change in equity of a business enterprise during a period from transactions and
other events and circumstances from nonowner sources. SFAS No. 130 is effective
for fiscal years beginning after December 15, 1997. This new standard is not
anticipated to have a significant impact on the Company's financial statements
based on the current structure and operations.

     In July 1997, the FASB issued SFAS No. 131, Disclosures About Segments of
an Enterprise and Related Information. SFAS No. 131 requires certain financial
and supplementary information to be disclosed on an annual

and interim basis for each reportable segment of an enterprise. SFAS No. 131 is
effective for fiscal years beginning after December 15, 1997. Unless
impracticable, companies would be required to restate prior period information
upon adoption. The Company implemented this standard in the first quarter of
1998. The Company intends to analyze segment reporting based on dark fiber and
lit fiber facilities. To date, the Company has recorded revenues and costs
related to dark fiber facilities only.

 (o) Litigation
     Certain claims arising in the ordinary course of business are pending
against the Company. In the opinion of management, these claims are without
merit and that there is no potential liability.


(2) RELATED PARTY TRANSACTIONS
     Applied Telecommunication Technologies, Inc. (ATTI) has provided the
Company with $1,594,433 of lease financing to date as reflected in Note 5. The
principal balance of the obligations is $912,837 and $533,740 as of December
31, 1996 and 1997, respectively. ATTI owns 12,409 shares of the Company's
outstanding common stock at December 31, 1997. One of ATTI's investment funds
owns 21,180 shares of the Company's Series A convertible preferred stock.

     During the years ended December 31, 1996 and 1997, the Company reimbursed
CMP and/or its subsidiary MaineCom Services primarily for personnel costs
related to the activities of the Company. The amount paid to CMP totaled
approximately $310,591 and $725,000 for the years ended December 31, 1996 and
1997, respectively. Approximately $0 and $29,779 was included in accounts
payable at December 31, 1996 and 1997, respectively.

     In addition, CMP includes the Company in its consolidated federal income
tax return. At December 31, 1996 and 1997, the amounts due under the
tax-sharing arrangement to the Company from CMP are included in refundable
taxes from related party and amounted to approximately $0 and $368,734,
respectively, for current and deferred income tax benefits related to CMP's
utilization of the Company's loss carryforwards (see Note 8).

     The Company is also affiliated with NU (see Note 1). The Company paid NU
approximately $3,719,404 in 1996 and $945,667 in 1997 for materials, labor and
other contractor charges. Approximately $357,100 and $494,500 was included in
accounts payable at December 31, 1996 and 1997, respectively.

     In 1994, the Company entered into an agreement with NU whereby NU waived
right-of-way fees for 10 years in return for the Company's guarantee to build
the fiber optic network to certain NU facilities and allow NU the use of 12
fibers on designated route segments in the NU service territory.

     The Company has employment contracts with three of its officers, two of
whom are also common and preferred stockholders of the Company. The contracts
are for three-year terms expiring at varying dates through April 2001 with an
annual compensation commitment of $412,000 in the aggregate. In addition, the
Company will record a one-time expense for a payment to one individual totaling
$500,000 upon the successful completion of an initial public offering in the
period incurred.

     Upon the successful completion of an initial public offering the Company
will record a one-time expense for a payment of $500,000 to MaineCom Services,
Inc.


(3) COMMUNICATIONS NETWORK CONSTRUCTION
     The Company is constructing a communications network in the northeast.
Costs directly related to the construction of the network are being capitalized
and will be depreciated over the 20-year estimated useful life of the fiber
optic transmission plant as individual segments of the system are placed in
service. During 1996 and 1997,

 (a) Note Payable to Related Party
     On October 7, 1997 the Company entered into a $30,000,000 construction
loan agreement with CMP. The Company paid CMP a commitment fee of $150,000. The
note bears interest at the LIBOR rate (5.72% at December 31, 1997) plus three
hundred basis points. Interest is payable quarterly in arrears commencing
January 1, 1998 through the conversion date (first day of the first month after
the completion of certain portions of the network (see Note 9)). Beginning on
the first day of the first month after the conversion date, the loan is payable
in equal monthly payments of principal plus interest accrued thereon. On
October 1, 2002, all amounts are due and payable in full. If required by the
Maine Public Utilities Commission (PUC), CMP has the option of demanding
payment in full on April 1, 1999 of any amounts of the loan outstanding on
April 1, 1999 that are necessary to cause CMP to be in compliance with the
PUC's requirements concerning CMP's capitalization. The loan is secured by a
perfected mortgage lien on the security interest in substantially all assets of
the Company.

(5) LONG-TERM OBLIGATIONS AND NOTE PAYABLE TO RELATED PARTY (Continued)

     As of December 31, 1997, $2,100,000 has been advanced under the loan
agreement. Additional advances will be made upon the completion of certain
conditions contained in the loan document, as defined. Subsequent to year-end
the Company was advanced an additional $8,100,000. In conjunction with the
note, the Company issued a warrant to purchase membership interest in FiveCom
LLC (see Note 7(d)). The fair market value of the warrant, $532,836, included
in deferred financing costs in the accompanying balance sheet, is being
amortized as interest expense over the term of the note. Upon successful
completion of an initial public offering and retirement of the note, the
Company will record a charge in the statement of operations for the remaining
balance of the deferred financing costs in the period extinguished.

 (b) Construction Loan Payable
     In March 1997, the Company entered into a $1,600,000 construction loan
agreement with a bank. The Company is required to maintain $800,000 in a
reserve account, which is included in the accompanying consolidated balance
sheets as of December 31, 1997 and March 31, 1998 as restricted cash. All
interest earned on the deposit becomes part of the reserve account. The reserve
account agreement remains in effect until the note is paid in full; however,
the bank may release the reserve account in the absence of any material default
under the loan agreement and a debt service coverage ratio greater than 1.5 to
1.0, as defined. As of December 31, 1997, the bank has not released any funds
in the reserve account. Under the agreement, the Company is required to
maintain certain covenants, as defined, including tangible net worth. As of
March 31, 1998, the Company was not in compliance with this covenant. The
Company received a waiver from the bank related to compliance with this
covenant through December 31, 1998.

 (c) ATTI Notes Payable
     Through August 1994 and October 1995, the Company entered into five notes
payable with ATTI. The notes bear interest at 13% and are payable in monthly
principal and interest installments ranging from $1,194 to $13,270 through
August 1999. In addition, the Company issued common stock warrants in
conjunction with the notes (see Notes 2 and 7(d)).

respectively.


 Dividends

     The holders of Series A and B preferred are entitled to receive dividends,
as defined, if and when declared by the Company's Board of Directors. To date
no dividends have been declared.


 Voting

     Each holder of outstanding shares of Series A and B preferred is entitled
to a number of votes equal to the number of whole shares of common stock into
which such share of Series A and B preferred held is then convertible. All
outstanding holders of Series A and Series B preferred shall vote together with
the holders of common stock as a single class, except holders of Series A
preferred shall vote as a separate class upon matters adversely affecting the
Series A preferred holders and holders of Series B preferred shall vote as a
separate class upon matters adversely affecting the Series B preferred holders.

Series A and B preferred and before payment to any class or series of stock
ranking junior to Series A and B preferred, Series A and B preferred
stockholders are entitled to receive, in the event of any voluntary or
involuntary liquidation or dissolution of the Company, (i) $23.6 and $24.7 per
share, respectively (subject to certain adjustments, as defined) plus any
dividends declared or accrued but unpaid or (ii) such amount per share as would
have been payable had each such share been converted into common stock.


 Conversion

     Each share of Series A and B preferred is convertible, at the option of
the holder, at any time after the date of issuance and without any additional
payment into such number of shares of Common Stock as is determined by dividing
$23.6 and $24.7, respectively, by the Conversion Price, as defined ($7.37 and

 (b) 1998 Stock Incentive Plan
     The Company's 1998 Stock Incentive Plan (the 1998 Plan) was adopted by the
Board of Directors on May 18, 1998 and is expected to be approved by the
Company's stockholders on May 26, 1998. The 1998 Plan provides for the grant of
incentive stock options, nonstatutory stock options, restricted stock awards
and other stock-based awards, including the grant of shares based on certain
conditions, the grant of securities convertible into common stock and the grant
of stock appreciation rights (collectively the Awards). Options may be granted
at an exercise price that may be less than, equal to or greater than the fair
market value of the common stock on the date of grant. Incentive stock options
and options intended to qualify as performance-based compensation may not be
granted at an exercise price less than the fair market value of the common
stock on the date of grant (or less than 110% of the fair market value in the
case of incentive stock options granted to optionees holding more than 10% of
the voting power of the Company). Options granted under the 1998 Plan typically
will vest over time, subject to acceleration upon change in control. Restricted
stock awards entitle recipients to acquire shares of common stock, subject to
the right of the Company to repurchase all or part of such shares from the
recipient in the event that the conditions specified in the applicable Award
are not satisfied prior to the end of the applicable restriction period
established for such Award. Under the 1998 Plan, the Board of Directors has the
right to grant other Awards based on the common stock having such terms and
conditions as the Board of Directors may determine, including the

grant of shares based on certain conditions, the grant of securities
convertible into common stock and the grant of stock appreciation rights.
Officers, employees, directors, consultant and advisers of the Company and its
subsidiaries are eligible to be granted Awards under the 1998 Plan.

     As of May 20, 1998, a total of 864,050 shares were reserved for issuance
under the 1998 Plan, of which the Company's Board of Directors approved the
issuance of 9% of the issued and outstanding stock of the Company as of the
planned initial public offering having an exercise price equal to the initial
public offering price.

 (c) Fair Value of Stock Options
     In October 1995, the FASB issued SFAS No. 123, Accounting for Stock-Based
Compensation. SFAS No. 123 requires the measurement of the fair value of stock
options to be included in the statements of income or disclosed in the notes to
financial statements. The Company has determined that it will continue to
account for stock-based compensation for employees under Accounting Principles
Board Opinion No. 25, Accounting for Stock Issued to Employees, and elect the
disclosure-only alternative under SFAS No. 123.

     The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option pricing model with the following assumptions
used for grants during the applicable period: dividend yield of 0% for all
periods; volatility of 0% for all periods; risk-free interest rate of 7.67% for
options granted during 1995 and a weighted average expected option term of two
years for all periods. The weighted average fair value per share of options
granted during 1995 was $0. No options were granted during 1996 and 1997.

 (d) Warrants
     From August 1994 to October 1995, the Company issued warrants to ATTI (see
Note 2) for the purchase of 4,579 shares of the Company's common stock at an
exercise price of $.15 per share. The warrants expire five years from the date
of grant. At the time of issuance, the Company recorded a charge of $178,
representing the fair market value of the warrants, as determined by the Board
of Directors.

     During July 1996, the Company issued a warrant to one of its advisers for
the purchase of 2,656 shares of membership interest in FiveCom LLC at an
exercise price of $125.80 per share. The warrant expires on April 30, 2001. At
the time of issuance, the Company recorded a charge of $8,595, representing the
fair market value of the warrant, as calculated using the Black-Scholes option
pricing model.

     During October 1997 and in connection with the CMP construction loan
agreement (see Note 5), the Company issued a warrant to purchase 5,876 shares
of membership interest in FiveCom LLC to the lender at an exercise price of
$.01 per share. The warrant expires on October 7, 2002. At the time of
issuance, the warrant was recorded as a discount on the agreement and as a
component of stockholders' equity in the accompanying consolidated balance
sheet at $532,836, the fair market value of the warrant, as calculated using
the Black-Scholes option pricing model. The discount is being amortized as
interest expense over the term of the debt. The warrant contains put and call
options and a right of first refusal. At the earlier of three years from the
date of the agreement or upon any reorganization, as defined, or an initial
public offering, the lender shall have the right to require the Company to
repurchase the warrant at fair market value, as defined. In addition, the
Company has the option to purchase the warrant prior to the warrant exercise at
the fair market value, as defined.

     Subsequent to year end, CMP exercised the warrant (see Note 14).

(8) INCOME TAXES
     As discussed in Note 2, the Company is included in CMP's consolidated
federal income tax return. The Company accounts for income taxes under SFAS No.
109, Accounting for Income Taxes, the objective of which is to recognize the
amount of current and deferred income taxes payable or refundable at the date
of the financial statements as a result of all events that have been recognized
in the accompanying consolidated financial statements, as measured by enacted
tax laws.

     The income tax provision (benefit) for the years ended December 31, 1995,
1996 and 1997 consists of the following:

Dark Fiber ........................   Fiber optic cable without any of the electronic or optronic equipment
                                      necessary to use the fiber for transmission.
Dense Wave Division
Multiplexing ......................   A technique for transmitting 8 or more different light wave frequencies on a
                                      single fiber to increase the information carrying capacity.
Digital ...........................   Describes a method of storing, processing and transmitting information
                                      through the use of distinct electronic or optical pulses that represent the binary
                                      digits 0 and 1. Digital transmission/switching technologies employ a sequence
                                      of discrete, distinct pulses to represent information, as opposed to the
                                      continuously variable analog signal.

Fiber Miles .......................   The number of strands of fiber in a length of fiber optic cable multiplied by
                                      the length of the cable in miles.
Fiber Optics ......................   A technology in which light is used to transport information from one point to
                                      another. Fiber optic cables are thin filaments of glass through which light
                                      beams are transmitted over long distances carrying large amounts of data.
                                      Modulating light on thin strands of glass produces major benefits in high-
                                      bandwidth, relatively low cost, low power consumption, small space needs,
                                      total insensitivity to electromagnetic interference and great resistance to
                                      bugging.

                                    speeds ranging from 56 kilobits per second to 1.5 megabits per second. This
                                    service is well-suited for connecting local area networks, but is not presently
                                    well suited for voice and video applications due to the variable delays which
                                    can occur. Frame Relay was designed to operate at high speeds on modern

                                    transmission lines into one high speed line by splitting the total available
                                    bandwidth into narrower bands (frequency division), or by allotting a common
                                    channel to several different transmitting devices, one at a time in sequence
                                    (time division).

                                    systems operating in the 1550 nm transmission window. The refractive index
                                    profile has been selected to provide non-zero dispersion over the Erbium-
                                    doped fiber amplifier passband region. This non-zero dispersion feature is
                                    important for system performance in high bit rate Dense Wavelength Division
                                    Multiplex (DWDM) applications.

Item 17. Undertakings.

     The Registrant will provide to the Underwriters at the closing specified
in the Underwriting Agreement certificates in such denominations and registered
in such names as required by the Underwriters to permit prompt delivery to each
purchaser.

     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 foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable.

     In the event that a claim for indemnification against such liabilities
(other than the payment by the Registration 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 such 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 such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

     The 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 a
   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 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 such securities at that time shall be deemed to
   be the initial bona fide offering thereof.
