                                 ------------
Of the 5,500,000 shares of Common Stock, $.01 par value per share (the "Common
Stock"), offered hereby (the "Equity Offering"), 4,000,000 are being sold by
NorthEast Optic Network, Inc. ("NorthEast Optic Network" or the "Company") and
1,500,000 are being sold by Central Maine Power Company, Northeast Utilities or
their affiliates (the "Selling Stockholders"), that, prior to the Equity
Offering, are collectively the owners of approximately 95% of the outstanding
Common Stock of the Company. The Company will not receive any proceeds from the
sale of the shares being sold by the Selling Stockholders. Following the
consummation of the Equity Offering, the officers, directors and other
affiliates of the Company, including the Selling Stockholders, will
beneficially own approximately 64.6% of the outstanding shares of Common Stock
of the Company (assuming no exercise of the Underwriters' (as defined)
over-allotment option).

Prior to the Equity Offering, there has been no public market for the Common
  Stock of the Company. It is currently estimated that the initial price to
  the public will be between $12.00 and $14.00 per share. See "Underwriting"
  for information relating to the factors to be considered in determining the
  initial price to the public.

Concurrently with the closing of the Equity Offering, the Company is offering
 $165.0 million aggregate principal amount of its  % Senior Notes Due 2008 (the
 "Debt Offering" and, together with the Equity Offering, the "Offerings"). The
 closing of each Offering is conditioned upon the closing of the other
 Offering. A portion of the proceeds of the Offerings will be used to repay
 indebtedness owed to one of the Selling Stockholders.

Application has been made to list the Common Stock on The Nasdaq Stock Market's
                National Market ("NNM") under the symbol NOPT.

                                 ------------
   
NorthEast Optic Network, Inc. ("NorthEast Optic Network" or the "Company") is
 offering (the "Debt Offering") $165.0 million aggregate principal amount of
 its   % Senior Notes Due 2008 (the "Notes"). Upon the closing of the Debt
 Offering, the Company will purchase U.S. Government Obligations (as defined)
 in such amount as will be sufficient, upon receipt of scheduled interest and
 principal payments on such securities, to provide for payment in full of the
 first seven scheduled interest payments on the Notes. Such securities will be
 pledged as security for the benefit of the holders of the Notes.

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 aggregate principal amount of the Notes at the redemption price
set forth herein with the net proceeds of one or more Public Equity Offerings
(as defined) if at least $107.25 million principal amount of the Notes remains
outstanding after any such redemption. On or after      , 2003, the Notes may
be redeemed at the option of the Company, in whole or in part, at the
redemption prices set forth herein. Upon a Change of Control (as defined), each
holder of Notes may require the Company to purchase all or a portion of such
holder's Notes at a purchase price equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the date of purchase.
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.

The Notes will be senior unsecured obligations of the Company. The Notes will
rank senior in right of payment to all subordinated indebtedness of the Company
and will rank pari passu in right of payment with all existing and future
indebtedness of the Company that is not by its terms subordinated in right and
priority to the Notes. In addition, claims of holders of the Notes will be
structurally subordinated to claims of holders of existing and future
indebtedness of the Company's subsidiaries. As of March 31, 1998, after giving
effect to the Offerings (as defined) and the application of the net proceeds
therefrom, the Company would have had outstanding approximately $165.4 million
of senior indebtedness (consisting of the Notes and indebtedness ranking pari
passu with the Notes) and no subordinated indebtedness, and the Company's
subsidiaries would have had outstanding approximately $289,000 of indebtedness.
Except for the restrictions on the ability of the Company to incur additional
indebtedness contained in the covenants described under "Description of the
Notes--Certain Covenants--Limitation on Indebtedness", "--Limitation on Liens"
and "--Limitation on Sale/Leaseback Transactions", 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.

Concurrently with the Debt Offering, the Company and certain shareholders of
 the Company are offering (the "Equity Offering" and, together with the Debt
 Offering, the "Offerings") 5,500,000 shares of Common Stock (6,325,000 shares
 if the over-allotment option granted to the underwriters is exercised in
 full). The closing of each Offering is conditioned upon the closing of the
 other Offering. A portion of the proceeds of the Offerings will be used to
 repay indebtedness owed to one of the principal stockholders of the Company.

   with an investment in the Notes, see "Risk Factors" beginning on page 12.

                                  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 over 900 route
miles, or more than 60,000 fiber miles, in New York and New England (the
"Northeast"). The Company believes that the Northeast, which in 1996
represented a $28.7 billion telephony services market and which the Company
believes 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
potential access to virtually any urban 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 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 construction of approximately 295 route
miles, or approximately 19,500 fiber miles, of the NEON system as of June 30,
1998, and currently operates fiber optic routes from Hartford, Connecticut to
Springfield, Massachusetts and from Nashua, New Hampshire to Portland, Maine.
The Company is currently engineering, constructing or acquiring additional
routes in New York, Connecticut, Massachusetts, Rhode Island and New Hampshire
to create a continuous fiber optic link between New York City and Portland,
Maine with access into and around Boston, Massachusetts and numerous other
major service areas in the Northeast. These additional routes are expected to
be substantially completed in 1998 and will add approximately 500 route miles,
or approximately 23,300 fiber miles, to the NEON system. The Company is also
planning to complete further expansion routes in 1999 into and around New York
City and other metropolitan areas along the NEON system. The completion of
routes 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 (the "NU Agreements") with the three principal operating
subsidiaries 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 (the "CMP Agreement") with
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) 41.4% and 53.5%, respectively, of the Company's
capital stock. In July 1998, the Company entered into


                                       3
<PAGE>

agreements with NEES Communications, Inc., a subsidiary of New England Electric
System, and BecoCom, Inc., a subsidiary of Boston Edison Company, to extend the
NEON system from Hudson, New Hampshire to Boston, Massachusetts terminating at
the Company's POP and Company-targeted carrier centers.


     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) inter-city routes and potentially
ubiquitous intra-city coverage in the local electric utility's urban service
territory, including throughout downtown areas and directly to 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 traditional ROWs, (iv)
desirable 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

     The Company intends to target 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 and are likely to make long-term capital commitments prior to
completion of construction. Carrier customers typically lease fiber optic
capacity under multi-year contracts with which they enhance or constitute 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 communications 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-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 that the Company expects to occur
in the communications industry.


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


                                       4

$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. 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: (i) rapid growth of communications traffic; (ii) capacity
required by new entrants to the telecommunications market; (iii) the need for
redundant routing and geographic diversity of ROWs to provide reliability in
the event of equipment failure, fiber line break or other outage; (iv) the need
to upgrade older communications networks; (v) accommodation of multimedia
(voice, data and video) and other potential high-bandwidth applications; and
(vi) communications carriers' desire for low-cost local 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:

   [bullet] 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, including potential connectivity to virtually any
            building in the utilities' urban service areas covered by the NEON
            system, faster and less costly installation on existing
            infrastructure and geographic diversity from traditional ROWs.

   [bullet] Target Carrier Customers. The Company intends to target
            communications carriers as customers, rather than end-users of
            telecommunications services, which the Company believes will allow
            it to maximize its opportunities to sell its capacity regardless of
            the end-user's selection of a retail provider, avoid the significant
            initial and ongoing investment required to attract and retain
            numerous retail customers and generate revenues quickly from carrier
            customers, which require large amounts of fiber optic capacity and
            are more likely to make long-term capital commitments prior to
            completion of construction.

   [bullet] Reduce Construction and Operating Costs. The Company is reducing its
            construction and operating costs by using primarily pre-existing
            electric utility transmission and distribution infrastructure,
            including towers, poles, ducts and conduits, in the construction of
            the NEON system, installing high fiber count cable and utilizing
            high quality, advanced fiber optic technology in the NEON system.

   [bullet] Establish a Reliable, Technologically Advanced Network. The Company
            is constructing the NEON system utilizing bi-directional,
            self-healing SONET ring architecture on primarily electric utility
            ROWs, which allow for enhanced physical security and geographic
            diversity. The Company plans to use what the Company believes to be
            the highest quality fiber optic cable and optronics available which
            enable the highest commercially available transmission capacity
            (OC-192) and data integrity level (10-15 Bit Error Rate).

   [bullet] Focus on High Demand Northeast Market. The Company believes that the
            Northeast market has one of the highest population densities and
            concentrations of businesses, universities, phone lines, personal
            computers and television sets in the country and is a region
            characterized by significant and growing demand for reliable
            broadband communications infrastructure.

   [bullet] Capitalize on Management Experience. The Company's management team
            includes individuals with significant experience in the
            telecommunications and utility industries which will be important in
            the build-out and management of the NEON system. Victor Colantonio,
            the Chairman of the Company and its founder and President, has 25
            years of experience in the telecommunications industry. Richard
            Crabtree, the Chairman of the Board and Chief Executive Officer of
            the Company, has 27 years of public utility company experience,
            including serving as Chief Financial Officer to CMP. Other senior
            executives of the Company also have extensive experience in the
            telecommunications industry.


                                       5
<PAGE>

   [bullet] Leverage Utility Relationships. The Company believes that its
            electric utility relationships enhance the Company's credibility
            with large carrier customers and create opportunities to establish
            relationships with other electric utility companies. In addition,
            through its utility relationships, the Company has outsourced
            substantially all of its engineering, design, routine maintenance
            and construction supervision requirements, thereby building on the
            utilities' significant resources and experience in the engineering
            and construction of large transmission and distribution networks.

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

Ranking ............................   The Notes will be senior unsecured (except to the extent of the
                                       Pledge Account and the Pledged Securities) obligations of the
                                       Company. The Notes will rank pari passu in right of payment
                                       with all existing and future indebtedness of the Company that
                                       is not by its terms subordinated in right and priority to the Notes
                                       and will be senior in right of payment to all future subordinated
                                       indebtedness of the Company. In addition, claims of holders of
                                       the Notes will be structurally subordinated to claims of holders
                                       of existing and future indebtedness of the Company's
                                       subsidiaries. As of March 31, 1998, after giving effect to the
                                       Offerings and the application of the net proceeds therefrom, the
                                       Company would have had outstanding approximately $165.4
                                       million of senior indebtedness (consisting of the Notes and
                                       $437,042 of other indebtedness) and no subordinated
                                       indebtedness, and the Company's subsidiaries would have had
                                       outstanding approximately $289,000 of indebtedness.
Restrictive Covenants ..............   The indenture under which the Notes will be issued (the
                                       "Indenture") will contain certain covenants that, among other
                                       things, will limit (i) the incurrence of additional Indebtedness
                                       (as defined) by the Company and its Restricted Subsidiaries (as
                                       defined), (ii) the payment of dividends and other Restricted
                                       Payments (as defined) 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

                      Summary Consolidated Financial Data

     The summary consolidated financial data presented below for each of the
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 summary 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
year. The balance sheet data presented below as of December 31, 1997 and March
31, 1998 is also presented on an as adjusted basis to give effect to the
Reorganization and on a pro forma as adjusted basis to give effect to the
Offerings and the application of the estimated net proceeds therefrom and to
the Reorganization.

(1) If the Reorganization had occurred as of January 1, 1997, the as adjusted
    impact on the Company's Statement of Operations for the year ended
    December 31, 1997 would reflect depreciation and amortization of
    $2,111,600, a net loss of $3,598,964 and a loss per share of $12.64, after
    giving effect to the Stock Split. The pro forma impact on the Company's
    Statement of Operations for the quarter ended March 31, 1998 would reflect
    depreciation and amortization of $694,318, a net loss of $999,957 and a
    loss per share of $3.51, after giving effect to the Stock Split.

(2) On a pro forma as adjusted basis giving effect to the Reorganization and to
    the Offerings (assuming a 121/2% per annum interest rate on the Notes) and
    the application of the net proceeds therefrom, (A) net loss and basic and
    diluted loss per share for 1997, (i) before the extraordinary charge,
    would have been $21,397,636 and $1.33, respectively, reflecting additional
    interest expense of $20,483,189 from the issuance of the Notes offset by
    interest income of $3,250,000 from the reinvestment of a portion of the
    net proceeds of the Offerings (assuming a 5% per annum interest rate on
    the $65,000,000 of restricted cash to be held in escrow), and (ii) after
    the extraordinary charge (which reflects the write-off of deferred
    financing costs of $1,241,806 related to the extinguishment of debt),
    would have been $22,639,442 and $1.41, respectively, and (B) net loss and
    basic and diluted loss per share for the first quarter of 1998, (i) before
    the extraordinary charge, would have been $5,390,641 and $0.34,
    respectively, reflecting additional interest expense of $5,064,434 from
    the issuance of the Notes offset by interest income of $812,500 from the
    reinvestment of a portion of the net proceeds of the Offerings (assuming a
    5% per annum interest rate on the $65,000,000 of restricted cash to be
    held in escrow), and (ii) after the extraordinary charge (which reflects
    the write-off of deferred financing costs of $1,454,175 related to the
    extinguishment of debt), would have been $6,844,816 and $0.43,
    respectively.
    

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

   
(4) Adjusted to give effect to the Reorganization. In connection with the
    Reorganization, the Company recorded an intangible asset to reflect the
    Company's acquisition of NU's minority interest in a subsidiary (NECOM
    LLC), in accordance with AICPA Accounting Interpretation 39 to APB Opinion
    No. 16, Business Combinations (AIN-39). If the intangible asset were
    recorded at December 31, 1997, the amount recorded would be $46,762,134.
    If the intangible asset were recorded at March 31, 1998, the amount
    recorded would be $47,076,632.

(5) Pro forma as adjusted to give effect to (i) the Offerings and the
    application of the estimated net proceeds therefrom, assuming an initial
    public offering price of $13.00 per share, the midpoint of the estimated
    price range, and after deducting the estimated underwriting discount and
    offering expenses payable by the Company, and the write-off of unamortized
    financing costs associated with debt extinguished and (ii) the
    Reorganization. See Note 4 above.

(6) EBITDA is defined herein as net loss before interest income (expense), net,
    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 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.

(7) For purposes of calculating the ratio of earnings (deficiency) 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 and 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
    $601,400, $1,474,524, $3,432,869, $416,419 and $995,487, respectively. For
    the year ended December 31, 1997 and for the three months ended March 31,
    1998, on a pro forma as adjusted basis the Company's earnings would have
    been insufficient to cover fixed charges by approximately $21,796,279 and
    $5,486,053, respectively. See Note 2 above.

                                 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 23% of the route miles and 21%
of the fiber 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 has incurred net losses from inception. Such losses were
approximately $487,000, $709,000, $960,000 and $293,000 for the years ended
December 31, 1995, 1996 and 1997 and the three months ended March 31, 1998,
respectively. 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 the Company's 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 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 has
generated 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 capital 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 not covered by utility ROWs currently available to the
Company, (ii) obtaining required governmental permits and certifications where
necessary and (iii) delays or disruptions resulting from physical damage, power
loss, defective equipment


                                       12

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 to install fiber optic cables from third
parties, including electric utilities, transit authorities and others. The
Company has not yet obtained the necessary ROWs to expand the NEON system to
encompass the planned New York local loop. The Company may be required to pay
cash or provide in-kind facilities for these ROWs or other ROWs to accommodate
extensions to the NEON system. In negotiating the terms for its ROWs, the
Company has sought, and expects to continue to seek, waivers or deferrals of
right-of-way fees while the NEON system is being constructed. For instance,
under its agreements with NU, the Company has, among other terms, agreed to pay
to NU mileage-based annual fees beginning in 2004 and a percentage of the gross
revenues of the Company generated over the ROWs granted by NU upon achieving
certain revenue levels. In addition, the Company has agreed to set aside for
NU's use a portion of the fibers along the ROWs granted by NU. Under its
agreements with CMP, the Company has agreed to pay 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, and the Company has
agreed to set aside certain fibers along the CMP ROWs for CMP's use. Although
the Company believes that its strategy of utilizing such ROWs, primarily from
electric utilities, will help to minimize the costs of acquiring ROWs for
telecommunications purposes, the Company is unable to predict with certainty
the cost of obtaining necessary ROWs, and there can be no assurance that it
will be able to obtain such ROWs on acceptable terms, if at all. If the Company
is unable to reach agreement on terms acceptable to the Company for the planned
completion of the NEON system, 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 rights to obtain route extensions
or other rights under its agreement with such entity may be adversely affected.
See "Business--Right-of-Way Agreements."

     The Company expects that it will require a substantial amount of capital
to complete the build-out of the NEON system as currently planned. The Company
currently estimates that its capital expenditure requirements for 1998 and 1999
will be approximately $54.0 million in each year. Additional funds will be
required to fund operating losses during these periods. The Company believes
that it will have sufficient capital to fund the build-out of the NEON system
as currently planned and its other working capital needs, contingent upon
completion of the Offerings. In the event that the proceeds of the Offerings
are less than anticipated or are otherwise insufficient to meet its capital
expenditure and other capital requirements, the Company would be required to
obtain funding from other sources to complete the construction of the NEON
system and to fund operating losses. Sources of funding may include vendor
financing, public offerings or private placements of equity and/or debt
securities, strategic customer alliances, and bank loans. However, there can be
no assurance that additional financing will be available to the Company or, if
available, that it can be obtained on a timely basis and on acceptable terms.
Failure to obtain such financing could result in the delay or curtailment of
the Company's development and expansion plans and expenditures or revisions to
the Company's business strategy. Any of these events would impair the Company's
ability to meet its debt service requirements and would have a material adverse
effect on its business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."


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 dark and lit 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 other alternatives in the Company's markets. The Company has
incurred and will continue to incur significant operating expenses and has made
and will continue to make significant capital investments, in each case based
upon certain expectations as to the anticipated customer demand for the
Company's services in its markets.


                                       13
<PAGE>

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
service revenues will come from a limited number of communications carriers.
Therefore, dissatisfaction with the Company's services by a relatively few
number of customers could have a material adverse effect on the Company's
business, financial condition and results of operations. Revenues through the
second quarter of 1997 consisted primarily of service fees from MCI. For the
year ended December 31, 1997, the Company's two largest customers, MCI and
Cellular One Group, accounted for 69% and 10% of total revenues, respectively,
and for the three months ended March 31, 1998, the Company's two largest
customers, MCI and Teleport, 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 staff, support 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. 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 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 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 because, unlike in the NU Agreements, in the CMP Agreement
the Company is not entitled to such acknowledgments. 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
has a limited easement in such property, the IRUs granted to the Company may be
alleged to be insufficient for the Company's uses. Certain landowners have
asserted claims against the Company on this basis, and, to date, in one such
case, rather than electing to contest the landowner's interpretation of the
scope of the easement, the Company has made a payment to such landowner to
acquire a ROW meeting the Company's requirements. The Company believes that the
easements granted by a substantial number of landowners to grantors of the
Company's IRUs are similar in scope to those with respect to which claims have
been asserted, and there can be no assurance that additional claims will not be
made in the future. Although litigation has not commenced in connection with
any of these claims, there can be no assurance that litigation will not
commence in the future. In the event that a substantial number of landowners
makes similar claims in the future and the Company is required to compensate
such landowners for the use of their property for the NEON system or seek
alternative routes for portions of the NEON system so affected, the Company's
business, financial condition and results of operations would be materially
adversely affected.


                                       14
<PAGE>

     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, certain of the Company's construction efforts are constrained by
the ability of NU and CMP to de-energize segments of their transmission and
distribution facilities in order to permit construction crews to work safely.
The Company has experienced construction delays in the past as a result of the
inability to timely de-energize certain segments and may experience such delays
in the future.

     The NU Agreements may be terminated under certain circumstances, including
the Company's failure to complete NUNet (as defined below under "Business--NU
Agreements") by September 1999, to maintain all necessary government permits,
licenses, franchises and approvals or its failure to pay amounts when due. In
addition, the CMP Agreement may be terminated by CMP under certain
circumstances, including the Company's failure to pay fees provided therein.
The termination of either the NU Agreements or the CMP Agreement would result
in the Company's loss of its ROWs under such agreements and would have a
material adverse effect on the Company's business, financial condition and
results of operations.

     Some of the agreements that the Company enters into to construct, operate
and install the NEON system may be nonexclusive, 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 end-users with private
communications 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, SNET, WorldCom and Teleport) and of other carriers (such as IXC
Communications, Qwest Communications International, Metromedia Fiber Network,
Level 3 Communications and RCN) who are planning to own or lease additional
networks which, if constructed, may employ advanced technology comparable to
that of the NEON system.

     NU and CMP each own or have an IRU in 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 Company's ROWs are nonexclusive in that other service providers (including
the utilities themselves) 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.


                                       15

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 provision of
telecommunications services on a common carrier basis offered through its
subsidiaries in New York and Connecticut, the Company cannot predict the future
regulatory status of its business. The FCC has recognized a class of private,
non-common carriers whose practice it is to make individualized decisions on
what terms and with whom to deal. These carriers may be subject to FCC
jurisdiction but are not currently extensively regulated. Such private carriers
include entities providing "telecommunications" for a fee as defined in the
1996 Act, which may include certain of the Company's offerings. In the event
that the Company becomes subject to the FCC's jurisdiction, it will be required
to comply with a number of regulatory requirements, including, but not limited
to rate regulation, reporting requirements, special payments, including
universal service assessments and access charges, and required service
offerings. Compliance with these regulatory requirements may impose substantial
administrative burdens on the Company. In addition, ILECs, CLECs 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.

     The Company is subject to state regulation, which can vary substantially
from state to state. The Company's subsidiaries in New York and Connecticut
have petitioned to provide telecommunications services on a certificated common
carrier basis. Therefore, such subsidiaries may be subject to the obligations
that applicable law places on all similarly certificated common carriers as
described above and elsewhere in this Prospectus, including: the filing of
tariffs, state regulation of certain service offerings and pricing,
requirements for interconnection with and resale to other carriers, payment of
regulatory fees and assessments, and reporting requirements. See
"Business--Regulation." At present, the Company does not anticipate that the
costs of compliance with these regulatory requirements, or any of the
regulatory requirements of other states to which it might become subject, will
have a material adverse effect on its operations, and expects its direct
competitors to be subject to similar regulatory requirements to the extent they
operate within these states. In some jurisdictions, the Company's pricing
flexibility for intrastate services may be limited because of regulation,
although the Company's direct competitors are expected to be subject to similar
restrictions.

     For a more detailed discussion of the regulatory environment in which the
Company conducts its business, see "Business--Regulation."


Dependence on Third-Party Contractors

     The Company has contracted to NU and CMP substantially all of the
engineering, routine maintenance and construction supervision activities
associated with the construction of that portion of the NEON system located on
NU and CMP properties and the Company has contracted to various third party
contractors, as well as CMP, the construction of the NEON system. As a result,
the Company may have less control over the timeliness and quality of the work
performed by such parties than if such work were to be performed by the
Company's own employees. The failure of NU, CMP or such contractors to complete
these activities in a timely manner, within anticipated budgets and in
accordance with the Company's quality standards and performance criteria, could
have a material adverse effect upon the Company's business, financial condition
and results of operations. In addition, as a result of their activities on
behalf of the Company, NU, CMP and such contractors may from time to time have
access to certain proprietary information about the Company. The Company's
agreements with NU, CMP and such contractors include provisions protecting the
confidentiality of such proprietary information.


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


                                       16
<PAGE>

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 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
purchases cable that includes fiber optic glass manufactured by Lucent
Technologies, Inc. ("Lucent"). 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, changes in the pricing arrangements with its suppliers
and manufacturers or delay in transitioning a replacement supplier's product
into the NEON system could disrupt the Company's operations and, if such
disruption continued for an extended period of time, have a material adverse
effect on the Company's business, financial condition and results of
operations.


Risk of Continued Decline in Prices

     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 does not control
whether a customer uses such bandwidth for voice, data or video signals. The
Company 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 some 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 competitive reliability, capacity and security via its
network. The Company's network and the infrastructures upon which it depends
are subject to physical damage, power loss, capacity limitations, software
defects, breaches of security and other disruptions beyond the control of the
Company 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 outage
related credits (a predetermined reduction or offset against the Company's
lease rate when a customer's leased facility is non-operational or otherwise
does not meet certain operating parameters) or damages in the event of a
disruption in service, which credits or damages could be substantial and could
have a material adverse effect on the Company's business, financial condition
and results of operations.


                                       17
<PAGE>

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, after giving effect to the Offerings and the application of
the estimated net proceeds therefrom, the Company would have had outstanding
approximately $165.4 million of indebtedness (consisting of the Notes and
$437,042 of other indebtedness) and the Company's ratio of total debt to total
capitalization would have been 60.29%. [D]Although the Indenture will contain
certain limitations on the ability of the Company and its subsidiaries to incur
additional Indebtedness, 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      , 2002, 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 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, after giving effect to the Debt Offering (as if it had occurred at the
beginning of the periods) and the application of the net proceeds therefrom,
the Company's earnings would have been insufficient to cover fixed charges by
approximately $21,796,279 and $5,486,053 respectively. Although the first seven
interest payments on the Notes will be paid from the [D] Pledge Account [E]
U.S. government obligations (and interest and principal payments thereon) to be
purchased by the Company upon consummation of the Offerings, thereafter, the
Notes will require annual cash interest payments of $    million, and the Notes
will mature on    , 2008. 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] Ranking of the Notes

     The indebtedness evidenced by the Notes will be senior unsecured (except
to the extent of the Pledge Account and the Pledged Securities) obligations of
the Company. The Notes will rank senior in right of payment to all subordinated
indebtedness of the Company and will rank pari passu in right of payment with
all existing and future indebtedness


                                       18
<PAGE>

of the Company that is not by its terms subordinated in right and priority to
the Notes. As of March 31, 1998, after giving effect to the Offerings and the
application of the net proceeds therefrom, the Company would have had
outstanding approximately $165.4 million of senior indebtedness (consisting of
the Notes and $437,042 of other indebtedness). The Notes 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, other than the
Pledge Account and the Pledged Securities (if such are still in existence),
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.

     The Notes will also be structurally subordinated to all existing and
future indebtedness of any subsidiary of the Company. 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. As of March
31, 1998, on a pro forma as adjusted basis after giving effect to the Offerings
and the application of the net proceeds therefrom and to the Reorganization,
the total liabilities of the Company's subsidiaries were approximately
$289,000, including trade payables.


Concentration of Stock Ownership; Potential Conflicts of Interest

     After consummation of the Offerings, CMP and NU will beneficially own or
control, in the aggregate, approximately 61.9% 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
certain existing ROW agreements for the engineering, design and construction
supervision 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 a Principal Stockholders Agreement dated May
28, 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, 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--Shareholders Agreement."

     The Company has agreed with Mode 1, an affiliate of NU, that for so long
as NU owns at least 10% of the Company's equity securities, the Company will
not take any action that would cause Mode 1 to fail to qualify as an "exempt
telecommunications carrier" under the Public Utility Holding Company Act of
1935, as amended, and as further amended by the Telecommunications Act of 1996.
 


[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"


                                       19
<PAGE>

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


[E] Shares Eligible for Future Sale

     Upon consummation of the Equity Offering, 16,066,335 shares of Common
Stock will be outstanding (16,891,335 shares if the Underwriters'
over-allotment option is exercised in full), of which 5,500,000 shares will be
freely tradeable (6,325,000 shares if the Underwriters' over-allotment option
is exercised in full). Of the 10,566,335 remaining shares, 9,950,780 shares
will be held by CMP, NU or their affiliates who, together with the Company and
its officers and directors, have entered into agreements 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 Agreements"). Upon expiration
of the Lock-Up 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 (the "Securities Act"). Upon consummation of the Equity
Offering, the Company will have outstanding stock options to purchase a total
of 1,705,272 shares of Common Stock, of which options for 284,210 shares will
be exercisable immediately 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 $13.00 per share
(representing the midpoint of the estimated price range), dilution to new
investors would be $9.70 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."


[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


                                       20
<PAGE>

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] 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 principal amount thereof, plus accrued and
unpaid interest, if any, 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, 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.


[D] Risks of Investing in Non-Investment Grade Debt

     The Notes have not been rated as investment-grade by any rating
institution and it is not expected that the Notes will be so rated. As a
result, holders of the Notes will have the risks associated with an investment
in non-investment grade debt. Historically, the market for non-investment grade
debt has been subject to disruptions that have caused substantial volatility in
the prices of such securities and greatly reduced liquidity for the holders of
such securities. If the Notes are traded, they may trade at a discount from
their initial offering price, depending upon prevailing interest rates, the
market for similar securities, the performance of the Company and certain other
factors. The liquidity of, and trading markets for, the Notes may also be
adversely affected by general declines in the market for non-investment grade
debt. Such declines may adversely affect the liquidity of, and trading markets
for, the Notes, independent of the financial performance of or prospects for
the Company. In addition, certain regulatory restrictions prohibit certain
types of financial institutions from investing in non-investment grade debt,
which may further suppress demand for 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 5,500,000
shares of Common Stock to the public in the Equity Offering. In addition, as
part of the Equity Offering the Company has granted the underwriters thereof an
option to purchase up to 825,000 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. Such conditions may not be
waived.


                               [E] DEBT OFFERING

     Concurrently with the Equity Offering, the Company is offering $165.0
million aggregate principal amount of its   % Senior Notes Due 2008 to the
public in the Debt Offering. Upon the closing of the Debt Offering, the Company
will purchase U.S. government obligations in such amount as will be sufficient,
upon receipt of scheduled interest and principal payments on such securities,
to provide for payment in full of the first seven scheduled interest payments
on the Notes. Such securities will be pledged as security for the benefit of
the holders of the Notes. The indenture under


                                       21
<PAGE>

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, consolidations
and transfers of assets. 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. Such conditions may not be
waived. See "Description of Certain Indebtedness."


                                USE OF PROCEEDS

     [E] The net proceeds to the Company from the Equity Offering are estimated
to be approximately $47.76 million (approximately $57.73 million if the
Underwriters' over-allotment option is exercised in full), assuming an initial
public offering price of $13.00 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 $159.45 million, after deducting the estimated underwriting
discount and offering expenses.

     [D] The net proceeds to the Company from the Debt Offering are estimated
to be approximately $159.45 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 $47.76 million (approximately
$57.73 million if the underwriters' over-allotment option is exercised in
full), assuming an initial public offering price of $13.00 per share and after
deducting the estimated underwriting discount and offering expenses.

     Of the net proceeds of the Offerings, estimated to be $207.2 million, the
Company intends to use approximately $65.0 million to purchase U.S. government
obligations in such amount as will be sufficient, upon receipt of scheduled
interest and principal payments on such securities, to provide for payment in
full of the first seven scheduled interest payments due on the Notes,
approximately $90.0 million for capital expenditures in 1998 and 1999
associated with the continued construction and expansion of the NEON system,
approximately $19.4 million (as of June 30, 1998) to repay certain indebtedness
and the balance for working capital and general corporate purposes. Such
indebtedness to be repaid includes approximately $17.9 million (as of June 30,
1998) of principal plus accrued interest under the Company's Construction Loan
Agreement with CMP (the "CMP Loan Agreement") and approximately $1.5 million
(as of June 30, 1998) of principal and 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 an annual rate of 9.25%, respectively, and matures in 2002 and 2007,
respectively. Among the general corporate purposes for which the Company
intends to use the proceeds of the Offerings are the payment of a bonus of
$500,000 to Mr. Colantonio in recognition of his efforts on behalf of the
Company and payment of a bonus of $500,000 to MaineCom in recognition of the
services provided by Mr. Crabtree, as an employee of MaineCom, to the Company.
See "Management--Executive Compensation." The payment of these amounts is
contingent upon the closing of the Offerings. Pending the foregoing uses, the
net proceeds of the Offerings will be invested in short-term, investment-grade
securities.


                              [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."


                                       22

                                 [E] DILUTION

     At March 31, 1998, after giving effect to the Reorganization and Stock
Split, the Company had a net tangible book value of approximately $10,870,000
or $0.90 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 $13.00 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 $53,080,000 or $3.30
per share. This represents an immediate increase in net tangible book value of
$2.40 per share to the existing stockholders and an immediate dilution of $9.70
per share to new investors. The following table illustrates this per share
dilution:

    Stock with a weighted average exercise price of $1.92 per share. See
    "Capitalization," "Management--1998 Stock Incentive Plan" and the Notes to
    Consolidated Financial Statements of the Company included elsewhere in

    number of shares held by existing stockholders to 10,562,735, or
    approximately 65.7% of the total number of shares of Common Stock
    outstanding after the Equity Offering (or approximately 62.5% if the

(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 3,470,470 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 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.

(3) Excludes (i) 3,600 shares of Common Stock issuable upon the exercise of
    stock options outstanding as of March 31, 1998 with an exercise price of
    $0.10 per share, (ii) an additional 2,436,105 shares of Common Stock
    reserved for future issuance under the Company's 1998 Stock Incentive
    Plan, and (iii) 174,367 shares of Common Stock issuable upon the exercise
    of warrants outstanding as of March 31, 1998 with a weighted average
    exercise price of $1.92 per share.

(4) The exercise of the CMP warrant 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.

   
(5) In connection with the Reorganization, the Company recorded an intangible
    asset of $47,076,632 to reflect the Company's acquisition of NU's minority
    interest in a subsidiary (NECOM LLC), in accordance with AICPA Accounting
    Interpretation 39 to APB Opinion No. 16, Business Combinations (AIN-39).
    

(6) Pro forma as adjusted reflects the write-off of deferred financing costs of
    $1,454,175 related to the extinguishment of debt with a portion of the
    proceeds of the Offerings.

    December 31, 1997 would reflect depreciation and amortization of
    $2,111,600, a net loss of $3,598,964 and a loss per share of $12.64, after
    giving effect to the Stock Split. The pro forma impact on the Company's
    Statement of Operations for the quarter ended March 31, 1998 would reflect
    depreciation and amortization of $694,318, a net loss of $999,957 and a
    loss per share of $3.51, after giving effect to the Stock Split.

(2) On a pro forma as adjusted basis giving effect to the Reorganization and to
    the Offerings (assuming a 121/2% per annum interest rate on the Notes) and
    the application of the net proceeds therefrom, (A) net loss and basic and
    diluted loss per share for 1997, (i) before the extraordinary charge,
    would have been $21,397,636 and $1.33, respectively, reflecting additional
    interest expense of $20,483,189 from the issuance of the Notes offset by
    interest income of $3,250,000 from the reinvestment of a portion of the
    net proceeds of the Offerings (assuming a 5% per annum interest rate on
    the $65,000,000 of restricted cash to be held in escrow), and (ii) after
    the extraordinary charge (which reflects the write-off of deferred
    financing costs of $1,241,806 related to the extinguishment of debt),
    would have been $22,639,442 and $1.41, respectively, and (B) net loss and
    basic and diluted loss per share for the first quarter of 1998, (i) before
    the extraordinary charge, would have been $5,390,641 and $0.34,
    respectively, reflecting additional interest expense of $5,064,434 from
    the issuance of the Notes offset by interest income of $812,500 from the
    reinvestment of a portion of the net proceeds of the Offerings (assuming a
    5% per annum interest rate on the $65,000,000 of restricted cash to be
    held in escrow), and (ii) after the extraordinary charge (which reflects
    the write-off of deferred financing costs of $1,454,175 related to the
    extinguishment of debt), would have been $6,844,816 and $0.43,
    respectively.

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

(4) Adjusted to give effect to the Reorganization. In connection with the
    Reorganization, the Company recorded an intangible asset to reflect the
    Company's acquisition of NU's minority interest in a subsidiary (NECOM
    LLC, in accordance with AICPA Accounting Interpretation 39 to APB Opinion
    No. 16, Business Combinations (AIN-39). If the intangible asset were
    recorded at December 31, 1997, the amount recorded would be $46,762,134.
    If the intangible asset were recorded at March 31, 1998, the amount
    recorded would be $47,076,632.

(5) Pro forma as adjusted to give effect to (i) the Offerings and the
    application of the estimated net proceeds therefrom, assuming an initial
    public offering price of $13.00 per share, the midpoint of the estimated
    price range, and after deducting the estimated underwriting discount and
    offering expenses payable by the Company and the write-off of unamortized
    financing costs associated with debt extinguished and (ii) the
    Reorganization. See Note 4 above.

(6) EBITDA is defined herein as net loss before interest income (expense), net,
    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 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.

(7) For purposes of calculating the ratio of earnings (deficiency) 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 expenses and capitalized interest, plus amortization
    of deferred financing costs. For the years ended December 31, 1993, 1994,
    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 $3,657, $202,710, $601,400, $1,474,524, $3,432,869, $416,419
    and $995,487, respectively. For the year ended December 31, 1997 and for
    the three months ended March 31, 1998, on a pro forma as adjusted basis,
    the Company's earnings would have been insufficient to cover fixed charges
    by approximately $21,796,279 and $5,486,053, respectively. See Note 2
    above.

                    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 over 900 route
miles, or more than 60,000 fiber miles, in New York and New England (the
"Northeast").

     The Company has already completed construction of approximately 295 route
miles, or approximately 19,500 fiber miles, of the NEON system as of June 30,
1998, and currently operates fiber optic routes from Hartford, Connecticut to
Springfield, Massachusetts and from Nashua, New Hampshire to Portland, Maine.
The Company is currently engineering, constructing or acquiring additional
routes in New York, Connecticut, Massachusetts, Rhode Island and New Hampshire
to create a continuous fiber optic link between New York City and Portland,
Maine with access into and around Boston, Massachusetts and numerous other
major service areas in the Northeast. These additional routes are expected to
be substantially completed in 1998 and will add approximately 500 route miles,
or approximately 23,300 fiber miles, to the NEON system. The Company is also
planning to complete further expansion routes in 1999 into and around New York
City and other metropolitan areas along the NEON system. The completion of
routes 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 primarily through the leasing of capacity on
its network and also 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. See "Business--Reorganization." The interests of the minority
owners of these subsidiaries are reflected on the Company's balance sheet as
minority interest in consolidated subsidiaries. As a result of the
Reorganization, such 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 MCI. The Company began recognizing revenues under recurring
lease arrangements in the third quarter of 1997.


                                       28
<PAGE>

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.

     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 the
first quarter of 1998 from $204,275 in the first quarter of 1997, a 10%
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 $32,987 in the first quarter of 1997. The increase resulted
from higher depreciation expense, 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
$137,620 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 $118,362 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 accrued right-of-way fees due to NU under
arrangements for right-of-way extensions 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.


                                       29
<PAGE>

     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.

     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 $13,773 for the year ended December 31, 1996 from
$42,598 for the year ended December 31, 1995. The decrease resulted from a
reduction in services provided to the Company's sole 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 1995. 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 NEON system 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 Savings 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 Sprint Communications
Company L.P. ("Sprint Communications") for telecommunications network services
and increased vendor payables. The payment by Sprint Communications is an
advance of the first three monthly payments for the portion of the NEON system
leased by Sprint Communications and expected to be placed in service by the
Company and accepted by Sprint Communications in late 1998. 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 prepayments and net operating losses.

     Cash flow from financing activities was $3,016,396 in the three months
ended March 31, 1998, $5,585,205 in the year ended December 31, 1997,
$11,565,481 in the year ended December 31, 1996 and $4,943,300 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
    


                                       30
<PAGE>

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 Peoples
Heritage Savings Bank. Upon the repayment of the loan from Peoples Heritage
Savings Bank, the Company will also be required to pay approximately $120,000
to CMP, representing accrued right-of-way fees that were deferred while such
loan was outstanding.

     Cash flow used in investing activities totaled $3,540,475, $8,798,251,
$6,738,898 and $4,619,702 in the three month period ended March 31, 1998, and
the one year periods ended December 31, 1997, December 31, 1996 and December
31, 1995, respectively. Cash requirements in all the periods 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
total capital expenditures to build out the NEON system as currently planned
will be approximately $128.0 million. Of this amount, the Company had already
expended approximately $23.0 million as of March 31, 1998. The Company
anticipates remaining total capital expenditures of approximately $51.0 million
in the remainder of 1998 and approximately $54.0 million in 1999 relating to
the build-out of the NEON system. The Company expects to incur additional
capital expenditures to enhance the capacity and penetration of the NEON system
after 1999. Cash provided by operations will not be sufficient to fund the
expansion and development of the NEON system 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 Indenture for the Notes contains certain covenants that, among other
things, limit the ability of the Company and its subsidiaries to incur
indebtedness, pay dividends, prepay subordinated indebtedness, repurchase
capital stock, engage in transactions with stockholders and affiliates, create
liens, sell assets and engage in mergers and consolidations.


Year 2000

     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 over 900 route
miles, or more than 60,000 fiber miles, in the Northeast. The Company believes
that the Northeast, which in 1996 represented a $28.7 billion telephony
services market and which the Company believes 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 potential access to virtually any urban
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
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 construction of approximately 295 route
miles, or approximately 19,500 fiber miles, of the NEON system as of June 30,
1998, and currently operates fiber optic routes from Hartford, Connecticut to
Springfield, Massachusetts and from Nashua, New Hampshire to Portland, Maine.
The Company is currently engineering, constructing or acquiring additional
routes in New York, Connecticut, Massachusetts, Rhode Island and New Hampshire
to create a continuous fiber optic link between New York City and Portland,
Maine with access into and around Boston, Massachusetts and numerous other
major service areas in the Northeast. These additional routes are expected to
be substantially completed in 1998 and will add approximately 500 route miles,
or approximately 23,300 fiber miles, to the NEON system. The Company is also
planning to complete further expansion routes in 1999 into and around New York
City and other metropolitan areas along the NEON system. The completion of
routes 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 the three principal operating subsidiaries 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) 41.4% and
53.5%, respectively, of the Company's capital stock. In July 1998, the Company
entered into agreements with NEES Communications, Inc., a subsidiary of New
England Electric System, and BecoCom, Inc., a subsidiary of Boston Edison, to
extend the NEON system from Hudson, New Hampshire to Boston, Massachusetts
terminating at the Company's POP and Company-targeted carrier centers.

     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) inter-city routes and, where permitted
by applicable rights, potentially ubiquitous intra-city coverage in the local
electric utility's urban service territory, including throughout downtown areas
and directly to 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, (iv) desirable 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.


                                       32
<PAGE>

     The Company intends to target 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 and are likely to make long-term capital commitments prior to
completion of construction. Carrier customers typically lease fiber optic
capacity under multi-year contracts with which they enhance or constitute 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 communications 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-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 that the Company expects to occur
in the communications industry.


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."
See "--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 5 million in 1993 to as
many as 62 million by the end of 1997. The Company believes that the


                                       33
<PAGE>

growth of communications traffic in the Northeast will be enhanced by the
favorable demographic characteristics of the region, including the high
population density, income and education levels and number of phone lines per
household. 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 constitute 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 in a number of communications
industry segments for new market entrants, 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 and
many of the carriers' routes currently run within the same ROWs. As a result,
many carriers are unable to establish secure redundant routing. 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.

     Need for 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 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, in 1996, approximately 88% of the ILECs
networks were comprised of copper cable. The ILECs 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 key LATAs in the Northeast. 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 LEC access and
egress charges, which often comprise a significant 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


                                       34
<PAGE>

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, will
be able to provide such local 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' urban service
territory covered by the NEON system, including throughout downtown areas and
directly to 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 electric utilities, 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.

     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 prior to completion of construction. To date, the
Company has entered into contracts with five carriers, including 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.

     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-existing 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, install conduits and ducts and erect
towers and poles prior to installation. In addition, the Company's electric
utility ROWs typically 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 is planning to install cable with up to 144 to
432 fiber optic strands on future installations, depending on the anticipated
demand for a particular route and the Company's ROW agreements. 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.

     Establish 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 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 planning to use Nortel's DWDM optronics and forward error correction
technology at high optical carrier ("OC") levels that enable the highest


                                       35
<PAGE>

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 Internet Protocol.

     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 $28.7 billion telephony services
market and which the Company believes 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 believes that the Northeast market is dependent in part upon antiquated
telecommunications 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 urban coverage.

     Capitalize on Management Experience. The Company's management team
includes individuals with significant experience in the telecommunications and
utility industries which will be important in the build-out and management of
the NEON System. Victor Colantonio, the Company's founder and President, has 25
years of experience in the telecommunications industry. The Company's Chairman
of the Board of Directors and Chief Executive Officer, Richard Crabtree, has 27
years of public utility company experience, including serving as Chief
Financial Officer of CMP. William Fennell, the Company's Chief Financial
Officer and Treasurer, held several positions at GTE Corporation 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 International
Communications Services Corp., a provider of network services.

     Leverage Utility Relationships. The Company intends to continue to
leverage its relationships with electric utilities, including NU and CMP, its
principal stockholders. 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, routine maintenance
and construction supervision requirements to these utilities, 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) these utilities have significant resources and
experience in the engineering and construction supervision of large
transmission and distribution networks, and (iv) the Company's experience with
these utilities creates opportunities to establish relationships with other
electric utility companies. The Company is currently in the process of pursuing
additional agreements with other 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 construction of approximately 295 route miles, or approximately
19,500 fiber miles, of the NEON system as of June 30, 1998, and currently
operates fiber optic routes from Portland, Maine to Nashua, New Hampshire and
Springfield, Massachusetts to Hartford, Connecticut. The Company is currently
engineering, constructing or acquiring additional routes in New York,
Connecticut, Massachusetts, Rhode Island and New Hampshire, to create a
continuous fiber optic link between New York City and Portland, Maine with
access into and around Boston, Massachusetts and numerous other major service
areas in the Northeast. These additional routes are expected to be completed in
1998 and will add approximately 500 route miles, or approximately 23,300 fiber
miles, to the NEON system. The Company is planning to complete further
expansion routes in 1999 into and around New York City and other metropolitan
areas along the NEON system. Upon completion of routes currently planned, the
NEON system will exceed 900 route miles or over 60,000 fiber miles, and will
enable the Company 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.

</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, because electric
utility ROWs may provide near-ubiquitous urban coverage at lower cost and
because deviations from other 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 other ROWs 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 urban 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 will contain up to 144 fiber strands in future
sheath designs. The second method is to install new all dielectric (non--


                                       37
<PAGE>

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 is expected to carry 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 216 fiber optic strands per cable depending on anticipated
demand for the particular route and the number of fiber optic strands allowed
by the Company's ROW agreements. 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.

     The Company offers end-to-end fiber optic capacity utilizing
bi-directional SONET 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.


     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
the three principal operating subsidiaries of NU 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 1998 (collectively, the "NU System"). NU and the Company
both agreed to use their best efforts to complete installation of the NU System
by September 1999. The Company agreed to pay the cost of installing the cable
and to utilize NU's engineering staff in carrying out the installation. Under
the NU Agreements, the Company agreed to pay to NU mileage-based annual fees
and a percentage of the gross revenues that the Company generates on the
portion of the NEON system located on NU ROWs.


     A portion of the NU System, comprised 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 2001, NU is not permitted to assign


                                       38
<PAGE>

any fibers or resell capacity on NUNet to certain specified carriers except for
certain limited purposes. After September 2001, NU will be free to use NUNet to
compete with the Company.

     Under the NU Agreements, 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
single mode fibers in such segment on terms no less favorable than those
provided to NU.

     The NU Agreements have an initial term of 30 years and expire in September
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 NU 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 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 along a certain route in CMP's service territory (the
"CMP System"). CMP and the Company both agreed to use their best efforts to
complete installation of the CMP System by January 1999. The Company has the
right to install additional cable in CMP's service territory, subject to the
approval of CMP, which must not be unreasonably withheld. The Company is
obligated to pay the cost of installing the cable.

     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 in January
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 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.


     Boston Agreements
     In July 1998, the Company entered into a Fiber Optic Lease Agreement with
NEES Communications, Inc., a subsidiary of New England Electric System (the
"NEES Com Agreement"), and a Fiber Optic Use Agreement with BecoCom, Inc., a
subsidiary of Boston Edison Company (the "BecoCom Agreement"). Pursuant to the
terms


                                       39
<PAGE>

of these agreements, the Company acquired the right to use certain fibers (the
"Company Fibers"), to be constructed and maintained by NEES Communications and
BecoCom, respectively, on a route running from Hudson, New Hampshire to Boston,
Massachusetts terminating at the Company's POP and Company-targeted carrier
centers. Under the terms of these agreements, the Company is required to pay a
monthly fee, and has agreed to share a portion of the revenue generated from
the use of the Company Fibers (in excess of a base revenue amount specified in
each agreement). The Company Fibers are expected to be available by December
31, 1998. Both the NEES Com Agreement and the BecoCom Agreement have an initial
term of 20 years, with the potential to negotiate for up to two additional,
consecutive five-year extensions. Although the BecoCom Agreement permits the
Company to grant capacity to third parties, the Company may not use the Company
Fibers under the BecoCom Agreement to handle local point to point services
within the service area generally prescribed as the Boston Edison service
territory. Nothing, however, precludes the Company from acquiring other sources
for local point to point services.

     Other Agreements
     In July 1998, the Company entered into an IRU agreement (the "Qwest
Agreement") with Qwest Communications Corporation ("Qwest") in which Qwest
agreed to grant the Company an IRU in certain fibers along a route to be
constructed between Boston and New York City (the "Boston-New York Segment").
In consideration of such grant, the Company agreed to pay to Qwest an IRU fee
in a series of installments. The Boston-New York Segment is expected to become
available to the Company by December 31, 1998. Although the Qwest Agreement
permits the Company to grant capacity in lit fiber to third parties, the
Company may not grant IRUs in dark fiber to third parties for five years
following the availability date of the Boston-New York Segment. The term of the
Qwest Agreement is for approximately 20 years; provided, however, that the
Qwest Agreement may be terminated at any time upon the occurrence of certain
uncured defaults by the Company or the loss of certain underlying rights held
by Qwest or other parties upon whom Qwest depends for its rights in the fiber.

     The Company also 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.

   
     Payments under Right-of-Way Agreements
     The aggregate amount accrued by the Company under its agreements that
provide for its ROWs used in the NEON system was $350,400, $435,100 and
$158,000 for the years ended December 31, 1996 and 1997 and the three-month
period ended March 31, 1998, respectively.
    


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 optronic 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 its leases with its customers, 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 optronic


                                       40
<PAGE>

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, potentially, 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, access in urban areas of its service territory
and the cost advantages that will allow the Company to lease its fiber optic
infrastructure at competitive 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 believes that communications carriers will be attracted to the
Company's dark fiber and lit fiber products. The contracts that the Company has
signed to date arose as a result of management's long standing relationships in
the telecommunications industry. The Company intends to leverage these
relationships and increase customer scope and penetration through a dedicated
sales force.


Customers

     The Company is targeting other telecommunications carriers as customers
and does not intend to offer its services directly to 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. The terms
of certain of these customer contracts are twenty years with varying lease
rates to be paid monthly. The monthly lease rates cover dark fiber and/or lit
fiber leased from the Company. In addition, the contracts typically provide for
"outage related credits," a predetermined reduction or offset against the
customer's lease rate when a customer's leased facility is non-operational or
does not meet the customer's operating parameters. 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.


                                       41
<PAGE>

   [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,
            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, 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.


Supply Relationships

     The Company has entered into agreements and arrangements for the supply of
equipment and services relating to the construction of the NEON system. In
choosing its suppliers, the Company uses such criteria as the quality and
performance of the product for the intended purpose, pricing, and the ability
of the supplier to meet the Company's delivery schedule and technical support
requirements. The Company purchases optronic network multiplexers and network
services from Northern Telecom Ltd. ("Nortel"), and cable from Fitel/Lucent
Technologies, Inc. ("Fitel") and FOCAS, Inc. ("FOCAS"). The cable purchased
from Fitel and FOCAS includes Lucent's patented "TrueWave" fiber, which the
Company believes contains certain favorable performance characteristics that
reduce the Company's investment in signal enhancing network equipment. 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, changes in
the pricing arrangements with its suppliers and manufacturers or delay in
transitioning a replacement supplier's product into the NEON system could
disrupt the Company's operations and, if such disruption continued for an
extended period of time, have a material adverse effect on the Company's
business, financial condition and results of operations. See "Risk
Factors--Dependence on Suppliers."


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."


                                       42
<PAGE>

     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, SNET, WorldCom and Teleport) and of other carriers (such as IXC
Communications, Qwest Communications International, Metromedia Fiber Network,
Level 3 Communications and RCN) who are planning to own or lease additional
networks which, if constructed, could employ advanced technology comparable to
that of the NEON system.

     Qwest Communications International recently announced that it had acquired
approximately 288 miles of fiber optic network 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 recently announced that it had acquired approximately 280 miles
of fiber optic network between New York and Boston. Another company, RCN, 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 AT&T, MCI and Sprint, 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 Communications International 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, 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.

     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 currently
utilized in its business and holds certain ownership interests in the cable
comprising the NEON system. The Company's installed fiber optic cable is laid
along 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.

     The Company's executive, administrative and sales offices are located at
its principal office in Waltham, Massachusetts. The Company leases this space
(approximately 4,375 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


                                       43
<PAGE>

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 April 1998, prior to the Reorganization, CMP exercised its warrants to
purchase 5,876 shares of membership interests in FiveCom LLC for an aggregate
exercise price of $58.76 and in July 1998, (i) each of the minority members in
FiveCom LLC (and each of 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; (ii) FiveCom
LLC and NECOM LLC were each merged with and into a wholly-owned subsidiary of
the Company; (iii) FiveCom of Maine LLC was merged into FiveCom of Maine, Inc.,
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." The shares of membership interest in FiveCom LLC
received by CMP upon exercise of its warrant were exchanged for 144,172 shares
of the Series B Convertible Preferred Stock of the Company, which shares had an
estimated value at the time of the Reorganization of approximately $4.3
million. Mr. Colantonio, the Company's President, and Mr. Musen, a Vice
President of the Company, exchanged their membership interests in FiveCom LLC
for 17,788 shares and 14,549 shares, respectively, of the Company's Series B
Convertible Preferred Stock, which shares had an estimated aggregate value at
the time of the Reorganization of approximately $542,000 and $443,000,
respectively. The Company believes that the value of the membership interests
exchanged in the Reorganization was equivalent to the value of the shares
issued in respect of each such membership interest. See "Certain Transactions."
 


Regulation

     While the Company believes it is not directly subject to common carrier
regulation (except to the extent is certified as a common carrier 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 indifferently for a fee, which would 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 telecommunications
service provider because of the nature of its activities in, and the statutory
provisions of, those two states; these subsidiaries, as authorized
telecommunications service providers, would also be subject to certain federal
law and regulation.


     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


                                       44
<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 vacated many of the FCC's guidelines. The Supreme Court has granted a
writ of certiorari to review the 8th Circuit's decision and is expected to
decide the case during its 1998-1999 term. 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 affect 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. However, this conclusion could be
affected by the FCC's review of its earlier decision, on remand from the U.S.
Court of Appeals for the District of Columbia Circuit, that local exchange
carriers offered dark fiber on a common carrier basis. 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. There is no assurance that the FCC may not take the
position that in making 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.

     As indicated above, the two subsidiaries of the Company which have applied
for authority to provide telecommunications services on a common carrier basis
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
"common carrier" or "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. The FCC's pending remand, described above, could also
definitively address the application of these requirements to the Company. If
the agency decides that such companies are telecommunications carriers or
common carriers, then the Company would be subject to certain regulatory
requirements, which 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


                                       45
<PAGE>

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 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. The
Company may be subject to this assessment even if it is found to not be a
common carrier and only provides service on a private contractual basis or
through the leasing of excess capacity to end-users. 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 interstate
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
intrastate services may be limited because of regulation, although


                                       46
<PAGE>

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 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 June 30, 1998, the Company employed 13 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 of the Board of Directors and Chief
    Executive Officer of the Company, Mr. Crabtree was President of MaineCom,
    a wholly-owned subsidiary of CMP, which paid his salary and benefits.
    Therefore, the Company did not pay any compensation to Mr. Crabtree for
    his services in 1997; however, the Company reimbursed MaineCom $67,808 for
    Mr. Crabtree's services in 1997. Effective July 1, 1998, Mr. Crabtree
    became a full-time employee of the Company with an annual base salary of
    $200,000. In June 1998 the Board of Directors of the Company granted to
    him an option to purchase up to 649,628 shares of the Company's Common
    Stock, which becomes exercisable in three equal annual installments,
    beginning one year after the closing of the Offerings. The exercise price
    per share for such option is the price to the public of a share of Common
    Stock in the Equity Offering. In addition, Mr. Crabtree has an opportunity
    to earn an annual bonus, targeted at 35% of his salary. Upon the closing
    of the Offerings, the Company will pay a cash bonus of $500,000 to
    MaineCom 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 effective upon the
    consummation of the Offerings and granted to him an option to purchase up
    to 649,628 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 for such option is the price to the public of a share of Common
    Stock in the Equity Offering. In addition, Mr. Colantonio has an
    opportunity to earn an annual bonus, targeted at 35% of his salary. In
    recognition of Mr. Colantonio's services to the Company in obtaining
    financing and establishing and maintaining the Company's utility and
    customer relationships, the Board of Directors determined that, 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 42,310 shares of Series A
    Preferred 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, dated July 1, 1998,
with Richard Crabtree. This agreement has an initial term expiring on December
31, 1998, and is extendable by mutual agreement of the parties for an
additional three years. The Agreement provides for an annual base salary of not
less than $200,000 per year, as well as an option to purchase 649,628 shares of
Common Stock at an exercise price equal to the price to the public of a share
of Common Stock in the Equity Offering, vesting in three equal annual
installments beginning on the first anniversary of the closing of the
Offerings. Pursuant to the Agreement, Mr. Crabtree is also entitled to
participate in the Company's executive incentive plan and has an opportunity to
earn an annual bonus, targeted at 35% of his base salary.

     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 $150,000. If Mr.
Colantonio's employment is terminated without cause after the occurrence of a
"Change of Control" (as defined


                                       50
<PAGE>

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.
Upon consummation of the Offerings, Mr. Colantonio's annual base salary will be
increased to $200,000.

     The Company has entered into an Employment Agreement, dated July 1, 1998,
with William Fennell. This Agreement has an initial term expiring on the later
of the third anniversary of the execution date or the third anniversary of the
closing of the Offerings. The Agreement provides for an annual base salary of
not less than $125,000 per year, as well as an option to purchase 162,407
shares of Common Stock at an exercise price equal to the price to the public of
a share of Common Stock in the Equity Offering, vesting in four equal
installments beginning on the date of the closing of the Offerings and on each
of the next three anniversaries of such date. Pursuant to the Agreement, Mr.
Fennell is also entitled to participate in the Company's executive incentive
plan and has an opportunity to earn an annual bonus, targeted at 25% of his
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, 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 an aggregate
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 162,407 shares of the Company's Common Stock, which
become exercisable as to 50% of such shares beginning on April 30, 1999 and as
to an additional 25% on each anniversary of such date. 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. In addition, in June 1998 the Board of Directors granted to Mr. Musen
an option to purchase 40,601 shares of the Company's Common Stock, exercisable
in full upon the closing of the Offerings, with an exercise price per share
equal to the price to the public of a share of Common Stock in the Equity
Offering.

     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 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 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 of the
Company (as defined therein). 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


                                       51
<PAGE>

of the 1998 Plan. The Board has authorized the Compensation Committee to
administer the granting of options to executive officers under the 1998 Plan.

     Upon consummation of the Equity Offering, a total of 2,436,105 shares will
be reserved for issuance under the 1998 Plan, of which 1,705,272 shares will be
subject to options granted to employees of the Company with an exercise price
per share equal to the price to the public of a share of Common Stock in the
Equity Offering. See "--Executive Compensation--Employment Agreements."


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 July 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. In addition, pursuant to the Restructuring and
Contribution Agreement, Mr. Colantonio, the Company's President, and Mr. Musen,
the Company's Vice President, Operations, exchanged their membership interests
in FiveCom LLC, a subsidiary 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 $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.

     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 $3,719,404 in 1996 and $945,667 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
Savings Bank under a $1.6 million construction loan agreement were outstanding.
The Company expects to repay the Peoples Heritage Savings Bank loan with the
proceeds of the Offerings. The amount of right-of-way payments accrued through
March 31, 1998 was approximately $120,000.

     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. The payment to MaineCom 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 June 30, 1998, the Company had outstanding
principal of approximately $17,875,000 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.

     MaineCom has certain rights with respect to the registration of its shares
of the capital stock of the Company. See "Description of Capital
Stock--Registration Rights."

                         DESCRIPTION OF CAPITAL STOCK

     As of March 31, 1998 (after giving effect to the Reorganization and the
Preferred Stock Conversion), there were outstanding an aggregate of 12,062,735
shares of Common Stock held of record by 21 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


                                       58
<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.


Registration Rights

     In November 1995, the Company and MaineCom entered into a Stock
Subscription Agreement, pursuant to which MaineCom purchased shares of the
Company's Series B Convertible Preferred Stock. Pursuant to the terms of the
Agreement, MaineCom has the right to have the shares of Common Stock issuable
upon conversion of its shares of Series B Convertible Preferred Stock
("Registrable Securities") included in any registration statement filed by the
Company relating to any public offering of the Company's Common Stock, except
to the extent the number of such shares may be limited by the managing
underwriter of any such offering. In addition, MaineCom may request that the
Company register all or part of the Registrable Securities at any time at least
180 days after the effective date of a registered underwritten offering of the
Company's Common Stock, provided that the anticipated aggregate net offering
price for such securities is at least $10,000,000.

   
     In May 1996, the Company issued a warrant to Oppenheimer & Co., Inc. (now
CIBC Oppenheimer Corp.) ("Oppenheimer"), relating to the right to purchase
65,167 shares of the Company's Series B Convertible Preferred Stock (the
"Oppenheimer Warrant"). Pursuant to the terms of the Oppenheimer Warrant, upon
Oppenheimer's request, the Company is required to include any securities
issuable with respect to the Oppenheimer Warrant ("Oppenheimer Registrable
Securities") in any registration statement filed by the Company (other than a
Registration Statement on Form S-8) relating to any public offering of the
Company's Common Stock. In addition, if requested by the holders of 50% of the
Oppenheimer Registrable Securities, the Company is required to register such
securities on a Registration Statement on Form S-3 when the Company becomes
eligible to use such form. However, in lieu of either of the above-referenced
registrations, the Company may purchase the Oppenheimer Registrable Securities
for an amount in cash equal to 95% of the difference between (a) the last sale
price of such securities on the day the request for registration is made and
(b) the exercise price in effect for the Oppenheimer Warrant on such day.
    


Principal Stockholders Agreement

     CMP and NU have entered into an agreement dated May 20, 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 $165.0
million aggregate principal amount of its    % Senior Notes Due 2008 pursuant
to the Debt Offering. 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.

     The Notes will be senior unsecured (except to the extent of the Pledge
Account and the Pledged Securities (each as defined in the Indenture))

interest semiannually each       and      , commencing on     , 1999. Upon the
closing of the Debt Offering, the Company will purchase U.S. government
obligations in such amount as will be sufficient, upon receipt of scheduled

full of the first seven scheduled interest payments on the Notes. Such
securities will be pledged as security for the benefit of the holders of the
Notes.

   
     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,

<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 U.S. Bank Trust National
Association, 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 Indenture will be subject to the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"). The following summary of the material
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. 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 senior unsecured (except to the extent of the Pledge
Account and the Pledged Securities) obligations of the Company, limited to
$165.0 million aggregate principal amount, and will mature on      , 2008. The
Notes will bear interest at the rate per annum shown on the cover page hereof
from      , 1998, 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    , 1999. 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

   
     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 principal amount), plus accrued and unpaid interest, if any, 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>
<CAPTION>
                                        Redemption
       Period                             Price

       2005 ........................
       2006 and thereafter .........       100
</TABLE>
    

     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 (except
to the extent of the Pledge Account and the Pledged Securities) obligations of
the Company. The Notes will be senior in right of payment to all subordinated
indebtedness of the Company and will rank pari passu in right of payment with
all existing and future


                                       61
<PAGE>

indebtedness of the Company that is not by its terms subordinated in right and
priority to the Notes. As of March 31, 1998, after giving effect to the
issuance of the Notes and the application of the net proceeds therefrom, the
Company's senior indebtedness outstanding would have been approximately $165.4
million (consisting of the Notes and $437,042 of other indebtedness).

     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. As of March 31, 1998, on
a pro forma as adjusted basis after giving effect to the Offering and the
application of the net proceeds therefrom and to the Reorganization, the total
liabilities of the Company's subsidiaries were approximately $289,000,
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."


Security

   
     The Indenture will provide that upon the closing of the Debt Offering, the
Company shall apply a portion of the net proceeds of the Debt Offering to
purchase, and pledge to the Trustee for the benefit of the holders of the
Notes, the Pledged Securities in such amount as will be sufficient upon receipt
of scheduled interest and principal payments on such securities to provide for
payment in full of the first seven scheduled interest payments due on the
Notes. The Company expects to use approximately $65.0 million of the net
proceeds of the Debt Offering to acquire the Pledged Securities; however, the
precise amount of securities to be acquired will depend upon the interest rates
on U.S. Government Obligations prevailing at the time of the closing of the
Debt Offering and the interest rate on the Notes. The Pledged Securities will
be pledged by the Company to the Trustee for the benefit of the Holders of the
Notes pursuant to a Pledge Agreement and will be held by the Trustee in the
Pledge Account. Pursuant to the Pledge Agreement, immediately prior to an
interest payment date on the Notes, the Company may either deposit with the
Trustee, from funds otherwise available to the Company, cash sufficient to pay
the interest scheduled to be paid on such date or the Company may direct the
Trustee to release from the Pledge Account proceeds sufficient to pay interest
then due. In the event that the Company exercises the former option, the
Company may thereafter direct the Trustee to release to the Company proceeds or
Pledged Securities from the Pledge Account in like amount. The failure by the
Company to pay interest on the Notes in a timely manner through           ,
2002 will constitute an immediate Event of Default under the Indenture, with no
grace period or cure period.
    

     Interest earned on the Pledged Securities will be added to the Pledge
Account. In the event that the funds or Pledged Securities held in the Pledge
Account exceed the amount sufficient, in the opinion of a nationally recognized
firm of independent public accountants selected by the Company, to provide for
payment in full of the first seven scheduled interest payments due on the Notes
(or, in the event an interest payment or payments have been made, an amount
sufficient to provide for payment in full of any interest payments remaining,
up to and including the seventh scheduled interest payment) the Trustee will
release to the Company at the Company's request any such excess amount. The
Notes will be secured by a first priority security interest in the Pledged
Securities and in the Pledge Account and the Pledged Securities and the Pledge
Account will also secure repayment of the principal amount of the Notes to the
extent of such security.

     Under the Pledge Agreement, assuming that the Company makes the first
seven scheduled interest payments on the Notes in a timely manner, all of the
Pledged Securities will have been released from the Pledge Account and
thereafter the Notes will be unsecured.


                                       62

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 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


                                       63
<PAGE>

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.


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
principal amount 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);


                                       64
<PAGE>

     (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 principal amount 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 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.


                                       65
<PAGE>

     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 a positive number that is 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
       $50.0 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";

   (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);

       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; provided that such Telecommunications
    


                                       66

       York City and White Plains, New York;

    (8) Indebtedness of the Company Incurred after the Issue Date in an amount
       which, when taken together with the amount of any other Indebtedness
       Incurred after the Issue Date pursuant to this clause (8) 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
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 (x) issuance or sale to a
       Subsidiary of the Company, (y) an issuance or sale to an employee stock
       ownership plan or to a trust
    


                                       67
<PAGE>

   
      established by the Company or any of its Subsidiaries for the benefit of
      their employees and (z) an issuance or sale that served as the basis for
      the Incurrance of Indebtedness pursuant to paragraph (b)(8) of the
      covenant described under Limitation on Indebtedness);
    

   (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, 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 or Capital Stock, the
   issuance or sale of which served as the basis for the Incurrence of
   Indebtedness pursuant to Section 4.03(b)(8)); 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 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


                                       68
<PAGE>

   
the Company (the payments, distributions, loans, advances and transfers
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 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


                                       69
<PAGE>

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 principal amount (without premium) 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 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


                                       70
<PAGE>

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

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

compliance with the covenant described under "--Limitation on Sale of Assets
and Subsidiary Stock."

     Future Guarantors. The Company shall cause each Restricted Subsidiary that

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 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

<PAGE>

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, as to any interest payment date
falling on or prior to     , 2002, and any such default in the payment of
interest on the Notes continued for 30 days as to any interest payment date
thereafter, (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 not being paid within any
applicable grace period after final maturity or being 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"), (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") or (ix) the security
interest under the Pledge Agreement shall cease to be in full force and effect
for any reason other than in accordance with its terms or such security
interest shall be declared invalid or unenforceable or the Company shall
assert, in any pleading in any court of competent jurisdiction, that such
security interest is invalid or unenforceable (the "security 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 principal of and accrued but unpaid interest on all the Notes to be
due and payable. Upon such a declaration, such principal and interest 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 principal of and interest 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.

     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


                                       72
<PAGE>

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 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, (vii) make any change in the amendment
provisions which require each holder's consent or in the waiver provisions or
(viii) make any change in the Pledge Agreement that would adversely affect the
rights of any Noteholder.

     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.

     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.


                                       73

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, the judgment default provision and the security
default provision described under "--Defaults" above and the limitations
contained in clause (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 and the Trustee shall release the
Pledged Securities from the Pledge Account. 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), (viii) or (ix) 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


     U.S. Bank Trust National Association 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.


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.

Restricted Subsidiaries as of such date of determination to (ii) EBITDA for the
four most recent consecutive fiscal quarters ending at least 45 days prior to

"Reference Period"); provided, however, that

   (1) if the transaction giving rise to the need to calculate the
       Consolidated Leverage Ratio is an Incurrence of Indebtedness, the amount
       of such Indebtedness shall be calculated after giving effect on a pro
       forma basis to such Indebtedness and to the discharge of any other
       Indebtedness repaid, repurchased, defeased or otherwise discharged with
       the proceeds of such new Indebtedness;

       as of the end of such fiscal quarter or if any Indebtedness that was
       outstanding as of the end of such fiscal quarter is to be repaid,
       repurchased, defeased or otherwise discharged on the date of the
       transaction giving rise to the need to calculate the Consolidated
       Leverage Ratio (other than, in each case, Indebtedness Incurred under
       any revolving credit agreement), EBITDA shall be calculated as if the
       Company or such Restricted Subsidiary had not earned the interest
       income, if any, actually earned during the Reference Period in respect
       of cash or Temporary Cash Investments used to repay, repurchase, defease
       or otherwise discharge such Indebtedness;

       Investment in any Restricted Subsidiary (or any Person which becomes a
       Restricted Subsidiary) or an acquisition of assets which constitutes all
       or substantially all of an operating unit of a business, EBITDA for the

       thereto (including the Incurrence of any Indebtedness) as if such
       Investment or acquisition occurred on the first day of the Reference
       Period; and


                                       76
<PAGE>

   (5) if since the beginning of the Reference Period any Person (that
       subsequently became a Restricted Subsidiary or was merged with or into
       the Company or any Restricted Subsidiary since the beginning of such
       Reference Period) shall have made any Asset Disposition, any Investment
       or acquisition of assets that would have required an adjustment pursuant
       to clause (3) or (4) above if made by the Company or a Restricted
       Subsidiary during the Reference Period, EBITDA for the Reference Period
       shall be calculated after giving pro forma effect thereto as if such
       Asset Disposition, Investment or acquisition occurred on the first day
       of the Reference Period.

     "Consolidated Net Income" means, for any period, the net income of the
Company and its consolidated Subsidiaries; provided, however, that there shall
not be included in such Consolidated Net Income:

   to the exclusion contained in clause (iv) below, the Company's equity in
   the net income of any such Restricted Subsidiary for such period shall be
   included in such Consolidated Net Income up to the aggregate amount of cash
   actually distributed by such Restricted Subsidiary during such period to
   the Company or another Restricted Subsidiary as a dividend or other
   distribution (subject, in the case of a dividend or other distribution paid
   to another Restricted Subsidiary, to the limitation contained in this
   clause applicable to such other Restricted Subsidiary) and (B) the
   Company's equity in a net loss of any such Restricted Subsidiary for such
   period shall be included in determining such Consolidated Net Income;

     (iv) any gain (but not loss) realized upon the sale or other disposition
   of any assets of the Company, its consolidated Subsidiaries or any other
   Person (including pursuant to any sale-and-leaseback arrangement) which is

   any gain (but not loss) realized upon the sale or other disposition of any
   Capital Stock of any Person;

                      [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
March 31, 1998), the Company will have outstanding an aggregate of 16,062,735
shares of Common Stock, assuming no exercise of the Underwriters'
over-allotment option and no exercise of outstanding options. Of these shares,
the 5,500,000 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 10,562,735 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,
10,159,995 shares will be eligible for sale upon expiration of the lock-up
agreements 180 days after the date of this Prospectus and 402,740 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 160,627 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


                                       86
<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 2,436,105 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] UNITED STATES FEDERAL TAX CONSEQUENCES

     The following is a summary of 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.
    


Non-United States Holders

     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.

     Each prospective Non-United States Holder is advised to consult its own
tax advisor with respect to the tax consequences of owning and disposing of
Common Stock.


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) such 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 equal to or 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


                                       88
<PAGE>

as may be specified by an applicable income tax treaty. For purposes of
determining whether tax is to be withheld 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 a Trade or 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.

               [D] UNITED STATES FEDERAL INCOME TAX CONSEQUENCES


     The following is a summary of material United States federal 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

     A United States Holder will recognize ordinary income when it receives or
accrues interest on the Notes in accordance with such United States Holder's
method of tax accounting. A United States Holder may be entitled to treat
interest income on the Notes as "investment income" for purposes of computing
certain limitations concerning the deductibility of investment interest
expense.


 Disposition of the Notes

     Generally, upon the sale or exchange or redemption of 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 which will be taxable as ordinary
interest income) 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 decreased by the amount of any principal
payments received by such holder in respect of such Note. 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 exchange 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 and at a maximum rate of 28 percent (15 percent if such
holder is in a 15 percent bracket) if the Note is held for more than 12 months
but not more than 18 months. Under proposed legislation, the 20% maximum rate
would apply to Notes held for more than 12 months by a United States Holder who
is a natural person, but there can be no assurance that such legislation will
be enacted.

<PAGE>

 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 United
States Holder (i) fails to furnish his social security or taxpayer
identification number ("TIN"), (ii) furnishes an incorrect TIN, (iii) is
notified by the IRS 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 IRS.
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.


Non-United States Holders

     As used herein, the term "Non-United States Holder" means any beneficial
owner of a Note 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

     Generally, any interest 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 on the Notes.


 Sale, Exchange or Redemption of the Notes

     Except 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 Reporting and Backup Withholding

     The Treasury regulations provide that backup withholding and information
reporting will not apply to payments of principal, premium, if any, and
interest on the Notes by the Company to a Non-United States 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 to its non-U.S. status under penalty of perjury or otherwise
establishes an exemption, provided that the broker does not


                                       91
<PAGE>

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-United States 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.

                               [E] UNDERWRITING


     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 Warburg Dillon Read LLC 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:

      Total ........................................   5,500,000
                                                       =========
</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 has granted to the Underwriters an option, expiring on the
30th day after the date of this Prospectus to purchase up to 825,000 additional
shares 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 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 275,000 shares of the Common Stock for employees, directors and
other persons with whom the Company has business relationships, including
potential marketing or supply partners and other persons who have been
supportive of the Company's efforts, who have expressed an interest in
purchasing such shares of Common Stock in the offering. The number of shares


                                       93
<PAGE>

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 civil 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.
Among the factors to be 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 Equity 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 have informed the Company that they do not expect
discretionary sales by the Underwriters to exceed 5% of the number of shares of
the Common Stock offered hereby.

     Under the terms and subject to the conditions contained in the
Underwriting Agreement dated               , 1998 (the "Underwriting
Agreement"), the underwriters named below (the "Underwriters") have severally
but not jointly agreed to purchase from the Company the following respective
principal amounts of the Notes:

     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 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 the non-defaulting Underwriter 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 civil 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.

                   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. In addition, CMP
purchased a 90.9% interest in the Company, giving it a controlling interest in
the Company. FiveCom LLC, NECOM LLC and FiveCom of Maine LLC commenced
operations upon their respective dates of organization. Prior to the
Reorganization completed on July 8, 1998 (see Note 14(a)--Reorganization) the
Company had a controlling interest in all entities except FiveCom of Maine LLC
(FiveCom of Maine LLC and the Company were commonly controlled by CMP). After
the Reorganization, FiveCom of Maine LLC became a wholly owned subsidiary of
the Company. As a result, the accompanying financial statements have been
restated to give retroactive effect to the merger of FiveCom of Maine LLC with
and into a subsidiary of the Company as a reorganization of entities under
common control in a manner similar to a pooling of interest.
    

     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.

 (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:

 (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 when facts and
circumstances indicate that the carrying amount of an asset may not be
recoverable based on the undiscounted projected cash flows of the related
asset. Should there be an 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 8(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 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. The Company believes that
these costs approximated the actual costs incurred by CMP and/or MaineCom
Services related to such personnel, and does not believe that such costs would
have been materially different had CMP and/or MaineCom Services not been
affiliates of the Company.

     CMP agreed to allow right-of-way payments otherwise payable by the Company
to accrue so long as amounts borrowed by the Company from a Bank under a $1.6
million construction loan agreement were outstanding. The amount of
right-of-way payments accrued through March 31, 1998 was approximately
$120,000.

   
     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 9).

(2) RELATED PARTY TRANSACTIONS (Continued)

   
     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's agreement with NU provides for payments on a per mile basis
for certain right-of-way extensions. Such payments are recognized ratably over
the 30-year term of the contract. Approximately $350,400 and $785,500 was
included in accrued right-of-way fees--related party at December 31, 1996 and
1997, respectively.
    

     The Company has employment contracts with four 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 July 2001 with an
annual compensation commitment of $537,000 in the aggregate. In addition, the
Company will record a one-time bonus 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 bonus for a payment of $500,000 to MaineCom Services.


(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, approximately 0 and 160 miles, respectively,
were placed in service. Approximately $114,000, $181,000 and $142,000 of
interest has been capitalized to communications network construction in
progress in each of the three years in the period ended December 31, 1997.


(4) INTANGIBLE ASSETS
     Intangible assets subject to amortization have been capitalized and are
amortized on a straight-line basis as follows:

</TABLE>

 (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 10)). 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.

     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 $15,775,000. In conjunction with the
note, the Company issued a warrant to purchase membership interest in FiveCom
LLC (see Note 8(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
December 31, 1997 and 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 March 31, 1998. The Company has
classified this debt as current in the accompanying financial statements, due
to noncompliance with this covenant subsequent to March 31, 1998.

     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 8(d)).

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

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.

 (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 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 advisors of the Company and its subsidiaries are
eligible to be granted Awards under the 1998 Plan.

     Upon consummation of the Equity Offering, a total of 2,436,105 shares will
be reserved for issuance under the 1998 Plan, of which 1,705,272 shares will be
subject to options granted to employees of the Company with an exercise price
per share 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 11,450 shares of the Company's common stock at an
exercise price of $.06 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 advisors for
the purchase of 2,656 shares of membership interest in FiveCom LLC at an
exercise price of $125.84 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.


(9) 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:

     The provision for income taxes for the year ended December 31, 1996
consists of alternative minimum and net worth taxes. The benefit from income
taxes for the year ended December 31, 1997 represents refundable income taxes
from CMP as a result of its tax-sharing agreement with CMP.

     The Company has recorded a deferred tax liability of $61,000 at December
31, 1997 related to the temporary differences associated with accelerated
depreciation.


   
(10) NETWORK CONSTRUCTION AND NU AND CMP CONTRACTS
     In 1994 the Company contracted for the rights to use NU property over an
initial 30-year term for the purpose of owning and operating the fiber optic
network facilities. At the end of the initial 30-year term, NU will have the
option to purchase the network on NU rights-of-way from the Company at the
appraised value, or to extend the agreement for an additional 30-year term with
an added payment incentive of 10% of revenues generated from the network built
on NU rights-of-way. Contractually, the Company is required to build 310 fiber
route miles in NU's service territory by September 27, 1999.

     Pursuant to the Company's agreement with NU, the right-of-way fees for
specified route segments have been waived 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. Costs of $2,348,156 associated with the construction of the
12 fibers are included in Prepaid right-of-way fees-related party in the
accompanying balance sheet and are being recognized as a cost-of-service
ratably by over 10 years.

     The Company's agreement with NU also provides for payments on a per mile
basis for certain right-of-way extensions. Such payments are being recognized
ratably over the 30-year term of the contract.
    

     In 1996, the Company contracted for the rights to use CMP's property over
an initial 30-year term for the purpose of owning and operating fiber optic
network facilities. At the end of the initial 30-year term, CMP will have the
option to purchase the network on CMP rights-of-way from the Company at the
appraised value, or to extend the agreement for an additional 10-year term with
an added payment incentive of 10% of revenues generated from the network built
on CMP rights-of-way.

   
     The Company's agreement with CMP provides for payments on a per mile
basis. Such payments are payable annually by January 31st of each year and are
recognized ratably over the 30-year term of the contract. CMP has agreed to
allow right-of-way payments otherwise payable by the Company to accrue so long
as amounts borrowed by the Company from a Bank under a $1.6 million
construction loan agreement were outstanding. The amount of right-of-way
payments accrued at December 31, 1997 and March 31, 1998 was approximately $0
and $120,000, respectively.

LLC (with Mode 1 owning the other 40%) and 33.3% of the outstanding membership
interests of FiveCom of Maine LLC (with MaineCom Services owning the other
66.7%).

     In order to simplify the corporate structure and in contemplation of the
Offerings, the Company's major stockholders decided to reorganize the Company.
In April 1998, prior to the Reorganization, CMP exercised its warrants to
purchase 5,876 shares of membership interests in FiveCom LLC for an aggregate
exercise price of $58.76 and on July 8, 1998, (i) each of the minority members
in FiveCom LLC (and each of Mode 1 and MaineCom Services) exchanged their
membership interests in FiveCom LLC, NECOM LLC and FiveCom of Maine LLC,
respectively, for 3,470,470 shares of the Series B Convertible Preferred Stock
of the Company; (ii) FiveCom LLC and NECOM LLC were each merged with and into
the Company; (iii) FiveCom of Maine LLC was merged into FiveCom of Maine, Inc.,
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.

     As a result of the Reorganization, (i) MaineCom Services ownership of the
Company was reduced to 52.82%, with Mode 1 gaining an ownership interest of
40.84% in the Company, and (ii) FiveCom LLC and NECOM LLC were merged with and
into the Company, and FiveCom of Maine LLC became a wholly-owned subsidiary of
the Company which was converted from a Massachusetts limited liability company
into a Delaware corporation.

     On July 8, 1998, the Company entered into a Restructuring and Contribution
Agreement with CMP, MaineCom Services (a wholly-owned subsidiary of CMP) and
Mode 1 (an affiliate of NU) relating to the restructuring of the Company.
Pursuant to this Agreement, each of MaineCom Services and Mode 1 exchanged
membership interests in subsidiaries of the Company for shares of the Series B 
Convertible Preferred Stock of the Company. In addition, pursuant to the 
Restructuring and Contribution Agreement, the Company's President and the 
Company's Vice President, Operations, exchanged their membership interests in 
FiveCom LLC, a subsidiary of the Company, for shares of the Series B Convertible
Preferred Stock of the Company.

     Prior to the reorganization, Fivecom, Inc., NU, and other minority
interests owned 82.7%, 9.9% and 7.4%, respectively, of FiveCom LLC membership
interests. CMP through its ownership in FiveCom, Inc. owned a 75.1% interest in
FiveCom LLC. In connection with the Reorganization, the Company will record an
intangible asset of approximately $47,000,000 to reflect the Company's exchange
of membership interest (acquisition) related to NU's

minority interest in a subsidiary (NECOM 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.

     Pro forma results of operations for the Company for the year ended
December 31, 1997 assuming that the Reorganization had occurred on January 1,
1997 would have been revenues of $394,704; operating loss of ($3,857,071); a
net loss of ($3,598,964); and a basic and diluted loss per share of $12.64.
    

 (b) Stockholders' Equity
     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 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 series of
preferred stock shall have 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.

     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
par value 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. All par
value amounts have been retroactively restated to reflect the reduction.

     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.

     On June 23, 1998 the Board of Directors voted to increase the authorized
common shares to 30,000,000.

     In July 1998, the Company's Board of Directors voted to effect a 2.5- to
- -1 common stock split. Series A and B convertible preferred stock will convert
at a rate equal to the common stock split. All share and per share amounts have
been retroactively restated to reflect the stock split.

 (c) Principal Stockholders Agreement
     CMP and NU have entered into a Principal Stockholders Agreement dated May
28, 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, unless both parties
agree. After the closing of the proposed equity offering and debt financing,
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 right-of-way agreements.

 (d) Qwest Agreement
     In July 1998, the Company entered into an agreement (the "Qwest
Agreement") with Qwest Communications Corporation ("Qwest") in which Qwest
agreed to grant to the Company an indefeasible right to use (IRU) in certain
fibers along a route to be constructed between Boston and New York City (the
"Boston-New York Segment"). In consideration of such grant, the Company agreed
to pay to Qwest an aggregate IRU fee to be paid in a series of installments.
The Boston-New York Segment is expected to become available to the Company by
December 31, 1998. The term of the Qwest Agreement is for the longer of 20
years or the useful economic life of the fiber subject

to the Qwest Agreement, provided, however, that the Qwest Agreement may be
terminated at any time upon the occurrence of certain uncured defaults by the
Company or the loss of certain underlying rights held by Qwest or the other
parties upon whom Qwest depends for its rights in the fiber.

   
 (e) BecoCom/NEES Communications Agreements
     In July 1998, the Company entered into a Fiber Optic Lease Agreement with
NEES Communications, Inc., a subsidiary of New England Electric System (the
"NEES Com Agreement"), and a Fiber Optic Use Agreement with BecoCom, Inc., a
subsidiary of Boston Edison Company (the "BecoCom Agreement"). Pursuant to the
terms of these agreements, the Company acquired the right to use certain fibers
(the "Company Fibers") to be constructed and maintained by NEES Communications
and BecoCom, respectively, on routes running from Hudson, New Hampshire to and
within Boston, Massachusetts. Under the terms of these agreements, the Company
is required to pay a monthly fee, and has agreed to share a portion of the
revenue generated from the use of the Company Fibers (in excess of a base
revenue amount specified in each agreement). NEES Communications and BecoCom
are each required to use their best commercial efforts to make the fibers
available to the Company by December 31, 1998. Both the NEES Com Agreement and
the BecoCom Agreement have an initial term of 20 years, with the potential to
negotiate for up to two additional, consecutive five-year extensions.

                  CONSOLIDATED PRO FORMA FINANCIAL STATEMENTS
                                  (Unaudited)

     The following unaudited consolidated pro forma financial statements give
effect to the Reorganization of entities under common control. These unaudited
consolidated pro forma financial statements have been prepared from, and should
be read in conjunction with, the historical financial statements and notes
thereto of NorthEast Optic Network, Inc.

     On July 8, 1998, the Company entered into a Restructuring and Contribution
Agreement with CMP, MaineCom Services (an affiliate of CMP) and Mode 1 (an
affiliate of NU) related to the restructuring of the Company. Pursuant to this
Agreement, each of MaineCom Services and Mode1 exchanged membership interests
in subsidiaries of the Company for shares of the Series B Convertible Preferred
Stock of the Company. In addition, pursuant to the Restructuring and
Contribution Agreement, the Company's President and the Company's Vice
President, Operations, exchanged their membership interests in FiveCom LLC, a
subsidiary of the Company for share of Series B Convertible Preferred Stock of
the Company. In connection with the Reorganization, the Company will record an
intangible asset of approximately $47,000,000 to reflect the Company's exchange
of membership interest (acquisition) related to NU's minority interest in a
subsidiary (NECOM LLC), in accordance with AICPA Accounting Interpretation 39
to APB Opinion No. 16, Business Combinations (AIN-39).

     The unaudited Consolidated Pro Forma Balance Sheet gives effect to the
Mergers as if they had occurred on March 31, 1998. The Consolidated Pro Forma
Statement of Operations for the three months ended March 31, 1998 give effect
to the Reorganization as if it had occurred on January 1, 1998. The
Consolidated Pro Forma Statement of Operations for the year ended December 31,
1997 gives effect to the Reorganization as if it had occurred on January 1,
1997.

     The Consolidated Pro Forma Financial Statements of the Company do not
purport to present the financial position or results of operations of the
Company had the Mergers or acquisitions been consummated at the dates
indicated, nor is it necessarily indicative of future operating results or
financial position of the reorganized companies.

                                  can be used by many different information systems, including local area
                                  networks, to deliver traffic at varying rates, permitting a mix of voice, data
                                  and video.
Backbone ......................   The through-portions of a transmission network, as opposed to spurs that
                                  branch off the through-portions.

                                  through a transmission medium, such as glass fibers, without distortion. The
                                  greater the bandwidth, the greater the information carrying capacity.
                                  Bandwidth is measured in Hertz, or "Hz" (analog), or Bits Per Second or
                                  "bps" (digital).
Bit ...........................   A contraction of the term Binary Digit, it is the basic unit in data
                                  communications. Bits are typically represented by ones or zeros.
Bit Error Rate ................   A measure of transmission quality stated as the expected probability of error
                                  per bit transmitted.
CAP ...........................   Competitive Access Provider.
Capacity ......................   The information carrying ability of a telecommunications facility.

Carrier Ring ..................   Local fiber optic network that connects one or more carrier facilities to a
                                  NEON POP.
Carrier's Carrier .............   A wholesale private telecommunications carrier offering services primarily to
                                  other carriers and not to the general public.
Central Office ................   A telephone company facility where subscribers' lines are joined to switching
                                  equipment for connecting with other subscribers, both locally and for long
                                  distance.
CLEC (Competitive Local
Exchange Carrier) .............   A company that competes with LECs in the local services market.
CMP ...........................   Central Maine Power Company
CMP Service Territory .........   The geographical areas prescribed by CMP's franchise service territory in the
                                  State of Maine.
Collocation ...................   The physical locating of a telecommunication carrier's switch in another
                                  carrier's premises that facilitates the interconnection of their respective
                                  switching equipment.
Common Carrier ................   A government defined group of private companies offering
                                  telecommunications services or facilities to the general public on a non-

Conduit ...........................   A pipe, usually made of metal, ceramic or plastic, that protects buried cables.
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

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.
Frame Relay .......................   A high-speed, data-packet switching service used to transmit data between
                                      computers. Frame Relay supports data units of variable lengths at access
                                      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
                                      fiber optic networks.
Gbps ..............................   Gigabits per second, which is a measurement of speed for digital signal

     The Delaware General Corporation Law and the Registrant's Certificate of
Incorporation and By-Laws provide for indemnification of the Registrant's
directors and officers for liabilities and expenses that they may incur in such

criminal action or proceeding, actions that the indemnitee had no reasonable
cause to believe were unlawful. Reference is made to the Registrant's Form of
Amended and Restated Certificate of Incorporation and Form of Amended and
Restated By-Laws to be filed as Exhibits hereto.

     The Underwriting Agreement provides that the Underwriters are obligated,
under certain circumstances, to indemnify directors, officers and controlling
persons of the Company against certain liabilities, including liabilities under
the Securities Act of 1933, as amended (the "Act"). Reference is made to the

(b) Financial Statement Schedules

because the information required to be set forth therein is not applicable or
is shown in the Financial Statements or Notes thereto.


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.

Dear Sirs:

         1. Introductory. NorthEast Optic Network, Inc., a Delaware corporation"
("Company"), proposes to issue and sell $165,000,000 principal amount of its __%
Senior Notes Due 2008 ("Offered Securities") to be issued under an indenture,
dated as of _________, 1998                                      ("Indenture"), 
between the Company and                        , as Trustee. The Company hereby
agrees with the several Underwriters named in Schedule A hereto ("Underwriters")
as follows:

         2. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, the several Underwriters that:

                  (a) A registration statement (No. 333-53441) relating to the
         Offered Securities, including a form of prospectus, has been filed with
         the Securities and Exchange Commission ("Commission") and either (i)
         has been declared effective under the Securities Act of 1933 ("Act")
         and is not proposed to be amended or (ii) is proposed to be amended by
         amendment or post-effective amendment. If such registration statement
         ("initial registration statement") has been declared effective, either
         (i) an additional registration statement ("additional registration
         statement") relating to the Offered Securities may have been filed with
         the Commission pursuant to Rule 462(b) ("Rule 462(b)") under the Act
         and, if so filed, has become effective upon filing pursuant to such
         Rule and the Offered Securities all have been duly registered under the
         Act pursuant to the initial registration statement and, if applicable,
         the additional registration statement or (ii) such an additional
         registration statement is proposed to be filed with the Commission
         pursuant to Rule 462(b) and will become effective upon filing pursuant
         to such Rule and upon such filing the Offered Securities will all have
         been duly registered under the Act pursuant to the initial registration
         statement and such additional registration statement. If the Company
         does not propose to amend the initial registration statement or if an
         additional registration statement has been filed and the Company does
         not propose to amend it, and if any post-effective amendment to either
         such registration statement has been filed with the Commission prior to
         the execution and delivery of this Agreement, the most recent amendment
         (if any) to each such registration statement has been declared
         effective by the Commission or has become effective upon filing
         pursuant to Rule 462(c) ("Rule 462(c)") under the Act or, in the case
         of the additional registration statement, Rule 462(b). For purposes of
         this Agreement, "Effective Time" with respect to the initial
         registration statement or, if filed prior to the execution and delivery
         of this Agreement, the additional registration statement means (i) if
         the Company has advised the Representatives that it does not propose to
         amend such registration statement, the date and time as of which such
         registration statement, or the most recent post-effective amendment
         thereto (if any) filed prior to the execution and delivery of this
         Agreement, was declared effective by the Commission or has become
         effective upon filing pursuant to Rule 462(c), or (ii) if the Company
         has advised the Representatives that it proposes to file an amendment
         or post-effective amendment to such registration statement, the date
         and time as of which such registration statement, as amended by 


<PAGE>


         such amendment or post-effective amendment, as the case may be, is
         declared effective by the Commission. If an additional registration
         statement has not been filed prior to the execution and delivery of
         this Agreement but the Company has advised the Representatives that it
         proposes to file one, "Effective Time" with respect to such additional
         registration statement means the date and time as of which such
         registration statement is filed and becomes effective pursuant to Rule
         462(b). "Effective Date" with respect to the initial registration
         statement or the additional registration statement (if any) means the
         date of the Effective Time thereof. The initial registration statement,
         as amended at its Effective Time, including all information contained
         in the additional registration statement (if any) and deemed to be a
         part of the initial registration statement as of the Effective Time of
         the additional registration statement pursuant to the General
         Instructions of the Form on which it is filed and including all
         information (if any) deemed to be a part of the initial registration
         statement as of its Effective Time pursuant to Rule 430A(b) ("Rule
         430A(b)") under the Act, is hereinafter referred to as the "Initial
         Registration Statement". The additional registration statement, as
         amended at its Effective Time, including the contents of the initial
         registration statement incorporated by reference therein and including
         all information (if any) deemed to be a part of the additional
         registration statement as of its Effective Time pursuant to Rule
         430A(b), is hereinafter referred to as the "Additional Registration
         Statement". The Initial Registration Statement and the Additional
         Registration Statement are herein referred to collectively as the
         "Registration Statements" and individually as a "Registration
         Statement". The form of prospectus relating to the Offered Securities,
         as first filed with the Commission pursuant to and in accordance with
         Rule 424(b) ("Rule 424(b)") under the Act or (if no such filing is
         required) as included in a Registration Statement, is hereinafter
         referred to as the "Prospectus". No document has been or will be
         prepared or distributed in reliance on Rule 434 under the Act.

                  (b) If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement: (i)
         on the Effective Date of the Initial Registration Statement, the
         Initial Registration Statement conformed in all material respects to
         the requirements of the Act, the Trust Indenture Act of 1939 ("Trust
         Indenture Act") and the rules and regulations of the Commission ("Rules
         and Regulations") and did not include any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading,
         (ii) on the Effective Date of the Additional Registration Statement (if
         any), each Registration Statement conformed, or will conform, in all
         material respects to the requirements of the Act, the Trust Indenture
         Act and the Rules and Regulations and did not include, or will not
         include, any untrue statement of a material fact and did not omit, or
         will not omit, to state any material fact required to be stated therein
         or necessary to make the statements therein not misleading and (iii) on
         the date of this Agreement, the Initial Registration Statement and, if
         the Effective Time of the Additional Registration Statement is prior to
         the execution and delivery of this Agreement, the Additional
         Registration Statement each conforms, and at the time of filing of the
         Prospectus pursuant to Rule 424(b) or (if no such filing is required)
         at the Effective Date of the Additional Registration Statement in which
         the Prospectus is included, each Registration Statement and the
         Prospectus will conform, in all material respects to the requirements
         of the Act, the Trust Indenture Act and the Rules and Regulations, and
         neither of such documents includes, or will include, any untrue
         statement of a material fact or omits, or will omit, to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading. If the Effective Time of the Initial
         Registration Statement is subsequent to the execution and delivery of
         this Agreement: on the Effective Date of the Initial Registration
         Statement, the Initial Registration Statement and the Prospectus will
         conform in all material respects to the requirements of the Act, the
         Trust Indenture Act and the Rules and Regulations, neither of such
         documents will include any untrue statement of a material fact or will
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading, and no
         Additional Registration Statement has been or will be filed. The two
         preceding sentences do not apply to statements in or omissions from a
         Registration Statement or the Prospectus based upon written information
         furnished to the Company by any Underwriter through the Representatives
         specifically for use therein, it being understood and agreed that the
         only such information is that described as such in Section 7(b) hereof.

                  (c) The Company has been duly incorporated and is an existing
         corporation in good standing under the laws of the State of Delaware,
         with power and authority (corporate and other) to own its properties
         and conduct its business as described in the Prospectus; and the
         Company is duly qualified to do business as a foreign corporation in
         good standing in all other jurisdictions in which its ownership or
         lease of property or the conduct of its business requires such
         qualification, except where the failure to be so qualified or in good
         standing would not have, individually or in the aggregate, a material
         adverse effect on the condition (financial or other), business,
         properties 


                                       2

         a whole (a "Material Adverse Effect").

                  (d) Each subsidiary of the Company has been duly incorporated
         and is an existing corporation in good standing under the laws of the
         jurisdiction of its incorporation, with power and authority (corporate
         and other) to own its properties and conduct its business as described
         in the Prospectus; and each subsidiary of the Company is duly qualified
         to do business as a foreign corporation in good standing in all other
         jurisdictions in which its ownership or lease of property or the
         conduct of its business requires such qualification in each case,
         except as would not have a Material Adverse Effect; all of the issued
         and outstanding capital stock of each subsidiary of the Company has
         been duly authorized and validly issued and is fully paid and
         nonassessable; and the capital stock of each subsidiary owned by the
         Company, directly or through subsidiaries, is owned free from liens,
         encumbrances and defects except as otherwise described in the
         Prospectus.

                  (e) The Indenture has been duly authorized and, if the
         Effective Time of a Registration Statement is prior to the execution
         and delivery of this Agreement, has been or otherwise upon such
         Effective Time will be duly qualified under the Trust Indenture Act
         with respect to the Offered Securities registered thereby; the Pledge
         Agreement has been duly authorized; the Offered Securities have been
         duly authorized; and when the Offered Securities are delivered and paid

         binding obligations of the Company, enforceable in accordance with
         their terms, subject to bankruptcy, insolvency, fraudulent transfer,
         reorganization, moratorium and similar laws of general applicability
         relating to or affecting creditors' rights and to general equity
         principles.

                  (f) No consent, approval, authorization, or order of, or
         filing with, any governmental agency or body or any court is required
         to be obtained or made by the company for the consummation of the
         transactions contemplated by this Agreement in connection with the
         issuance and sale of the Offered Securities by the Company, except such
         as have been obtained and made under the Act and the Trust Indenture
         Act, the Securities Exchange Act of 1934 (the "Exchange Act") and such
         as may be required under state or foreign securities laws.

                  (g) The execution, delivery and performance of this Agreement,
         and the consummation of the transactions herein contemplated will not
         result in a breach or violation of any of the terms and provisions of,
         or constitute a default under, any existing statute, any existing rule,
         regulation or order naming the Company of any governmental agency or
         body or any court, domestic or foreign, having jurisdiction over the
         Company or any subsidiary of the Company or any of their properties, or
         any agreement or instrument to which the Company or any such subsidiary

         subject (except as would not have a Material Adverse Effect), or the
         charter or by-laws of the Company or any such subsidiary.

                  (h) This Agreement has been duly authorized, executed and
         delivered by the Company.

                  (i) Except as disclosed in the Prospectus, the Company and its
         subsidiaries have good and marketable title to all real properties and
         all other properties and assets owned by them, in each case free from
         liens, encumbrances and defects that would materially affect the value
         thereof or materially interfere with the use made or to be made thereof
         by them; except as disclosed in the Prospectus, the Company and its
         subsidiaries hold any leased real or personal property under valid and
         enforceable leases with no exceptions that would materially interfere
         with the use made or to be made thereof by them; and except as
         described in the Prospectus, the Company and its subsidiaries hold
         easements and indefeasible rights of use under valid and enforceable
         agreements with no exceptions that would materially interfere with the
         use made or to be made thereof by them.

                  (j) The Company and its subsidiaries possess adequate
         certificates, authorities or permits issued by appropriate governmental
         agencies or bodies necessary to conduct the business now operated by
         them (except where the failure to possess the same would not
         individually or in the aggregate have a Material Adverse Effect) and
         have not received any notice of proceedings relating to the revocation
         or modification of any such certificate, authority or permit that, if


                                       3
<PAGE>


         determined adversely to the Company or any of its subsidiaries, would
         individually or in the aggregate have a Material Adverse Effect.

                  (k) No labor dispute with the employees of the Company or any
         subsidiary exists or, to the knowledge of the Company, is imminent that
         might have a material adverse effect on the Company and its
         subsidiaries taken as a whole.

                  (l) The Company and its subsidiaries own, possess or can
         acquire on reasonable terms, adequate trademarks, trade names and other
         rights to inventions, know-how, patents, copyrights, confidential
         information and other intellectual property (collectively,
         "intellectual property rights") necessary to conduct the business now
         operated by them, or presently employed by them, and have not received
         any notice of infringement of or conflict with asserted rights of
         others with respect to any intellectual property rights that, if
         determined adversely to the Company or any of its subsidiaries, could
         individually or in the aggregate reasonably be expected to have a
         Material Adverse Effect.

                  (m) Except as disclosed in the Prospectus, neither the Company
         nor any of its subsidiaries is in violation of any statute, any rule,
         regulation, decision or order of any governmental agency or body or any
         court, domestic or foreign, relating to the use, disposal or release of
         hazardous or toxic substances or relating to the protection or
         restoration of the environment or human exposure to hazardous or toxic
         substances (collectively, "environmental laws"), owns or operates any
         real property contaminated with any substance that is subject to any
         environmental laws, is liable for any off-site disposal or
         contamination pursuant to any environmental laws, or is subject to any
         claim relating to any environmental laws, which violation,
         contamination, liability or claim could individually or in the
         aggregate reasonably be expected to have a Material Adverse Effect on
         the Company and its subsidiaries taken as a whole; and the Company is
         not aware of any pending investigation which might lead to such a
         claim.

                  (n) Except as disclosed in the Prospectus, there are no
         pending actions, suits or proceedings against or affecting the Company,
         any of its subsidiaries or any of their respective properties that, if
         determined adversely to the Company or any of its subsidiaries, would
         individually or in the aggregate have a Material Adverse Effect, or
         would materially and adversely affect the ability of the Company to
         perform its obligations under the Indenture or this Agreement, or which
         are otherwise material in the context of the sale of the Offered
         Securities; and no such actions, suits or proceedings are threatened
         or, to the Company's knowledge, contemplated.

                  (o) The financial statements included in each Registration
         Statement and the Prospectus present fairly the financial position of
         the Company and its consolidated subsidiaries as of the dates shown and
         their results of operations and cash flows for the periods shown, and
         such financial statements have been prepared in conformity with the
         generally accepted accounting principles in the United States applied
         on a consistent basis and the assumptions used in preparing the pro
         forma financial information included in each Registration Statement and
         the Prospectus provide a reasonable basis for presenting the
         significant effects directly attributable to the transactions or events
         described therein, the related pro forma adjustments give appropriate
         effect to those assumptions, and the pro forma columns therein reflect
         the proper application of those adjustments to the corresponding
         historical financial statement amounts.

                  (p) Except as disclosed in the Prospectus, since the date of
         the latest audited financial statements included in the Prospectus
         there has been no material adverse change, nor any development or event
         involving a prospective material adverse change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and its subsidiaries taken as a whole, and, except as
         disclosed in or contemplated by the Prospectus, there has been no
         dividend or distribution of any kind declared, paid or made by the
         Company on any class of its capital stock.

                  (q) The Company is not and, after giving effect to the
         offering and sale of the Offered Securities and the application of the
         proceeds thereof as described in the Prospectus, will not be an
         "investment company" as defined in the Investment Company Act of 1940.

                  (r) Neither the Company nor any of its affiliates does
         business with the government of Cuba or with any person or affiliate
         located in Cuba within the meaning of Section 517.075, Florida Statutes
         and the Company agrees to comply with such Section if prior to the
         completion of the distribution of the Offered Securities it commences
         doing such business.

                  (s) Except as disclosed in the Prospectus, neither the Company
         nor any of subsidiaries is currently, nor will the conduct of its
         business as described in the Prospectus cause it to be in the future,
         subject to the provisions of the Communications Act of 1934, as amended
         by the Telecommunications Act of 1996 (the "Communications Act") or to
         any rules, regulations and policies of the Federal Communications
         Commission (the "FCC") related thereto.

                  (t) The Company and its subsidiaries are in compliance in all
         material respects with all federal, state and local telecommunications
         laws, rules, regulations and policies to which they are subject,
         including, with respect to subsidiaries, the Communications Act and the
         related rules, regulations and policies of the FCC.

several Underwriters that:

                  (a) If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement, the
         Company will file the Prospectus with the Commission pursuant to and in
         accordance with subparagraph (1) (or, if applicable and if consented to
         by CSFBC, subparagraph (4)) of Rule 424(b) not later than the earlier
         of (A) the second business day following the execution and delivery of
         this Agreement or (B) the fifteenth business day after the Effective
         Date of the Initial Registration Statement. The Company will advise
         CSFBC promptly of any such filing pursuant to Rule 424(b). If the
         Effective Time of the Initial Registration Statement is prior to the
         execution and delivery of this Agreement and an additional registration
         statement is necessary to register a portion of the Offered Securities
         under the Act but the Effective Time thereof has not occurred as of
         such execution and delivery, the Company will file the additional
         registration statement or, if filed, will file a post-effective
         amendment thereto with the Commission pursuant to and in accordance
         with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date
         of this Agreement or, if earlier, on or prior to the time the
         Prospectus is printed and distributed to any Underwriter, or will make
         such filing at such later date as shall have been consented to by
         CSFBC.

                  (b) The Company will advise CSFBC promptly of any proposal to
         amend or supplement the initial or any additional registration
         statement as filed or the related prospectus or the Initial
         Registration Statement, the Additional Registration Statement (if any)
         or the Prospectus and will not effect such amendment or supplementation
         without CSFBC's consent; and the Company will also advise CSFBC
         promptly of the effectiveness of each Registration Statement (if its
         Effective Time is subsequent to the execution and delivery of this
         Agreement) and of any amendment or supplementation of a Registration
         Statement or the Prospectus and of the institution by the Commission of
         any stop order proceedings in respect of a Registration Statement and
         will use its best efforts to prevent the issuance of any such stop
         order and to obtain as soon as possible its lifting, if issued.

                  (c) If, at any time when a prospectus relating to the Offered
         Securities is required to be delivered under the Act in connection with
         sales by any Underwriter or dealer, any event occurs as a result of
         which the Prospectus as then amended or supplemented would include an
         untrue statement of a material fact or omit to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or if it is
         necessary at any time to amend the Prospectus to comply with the Act,
         the Company will promptly notify CSFBC of such event and will promptly
         prepare and file with the Commission, at its own expense, an amendment
         or supplement which will correct such statement or omission or an
         amendment which will effect such compliance. Neither CSFBC's consent
         to, nor the Underwriters' delivery of, any such amendment or supplement
         shall constitute a waiver of any of the conditions set forth in Section
         6.

                  (d) As soon as practicable, but not later than the
         Availability Date (as defined below), the Company will make generally
         available to its securityholders an earnings statement covering a
         period of at least 12 months beginning after the Effective Date of the
         Initial Registration Statement (or, if later, the Effective Date of the
         Additional Registration Statement) that will satisfy the provisions of
         Section 11(a) of the Act. For the purpose of the preceding sentence,
         "Availability Date" means the 45th day after the end of the fourth
         fiscal quarter following the fiscal quarter that includes such
         Effective Date, except that, if such fourth fiscal quarter is the last
         quarter of the Company's fiscal year, "Availability Date" means the
         90th day after the end of such fourth fiscal quarter.

                  (e) The Company will furnish to the Representatives copies of
         each Registration Statement (three of which will be signed and will
         include all exhibits), each related preliminary prospectus, and, so
         long as a prospectus relating to the Offered Securities is required to
         be delivered under the Act in connection with sales by any Underwriter
         or dealer, the Prospectus and all amendments and supplements to such
         documents, in each case in such quantities as CSFBC requests. The
         Prospectus shall be so furnished on or prior to 5:00 P.M., New York
         time, on the business day following the later of the execution and
         delivery of this Agreement or the Effective Time of the Initial
         Registration Statement. All other documents shall be so furnished as
         soon as available. The Company will pay the expenses of printing and
         distributing to the Underwriters all such documents.

                  (f) The Company will arrange for the qualification of the
         Offered Securities for sale under the laws of such jurisdictions in the
         United States and Canada as CSFBC designates and will continue such
         qualifications in effect so long as required for the distribution.

                  (g) During the period of 3 years hereafter, the Company will
         furnish to the Underwriters, as soon as practicable after the end of
         each fiscal year, a copy of its annual report to stockholders for such
         year; and the Company will furnish to the Underwriters (i) as soon as
         available, a copy of each report and any definitive proxy statement of
         the Company filed with the Commission under the Securities Exchange Act
         of 1934 or mailed to stockholders, and (ii) from time to time, such
         other information concerning the Company as CSFBC may reasonably
         request, which such other information shall be kept confidential by the
         Underwriters.

                  (h) The Company will pay all expenses incident to the
         performance of its obligations under this Agreement, for any filing
         fees and other expenses (including fees and disbursements of counsel)
         incurred in connection with qualification of the Offered Securities for
         sale under the laws of such jurisdictions in the United States and
         Canada as CSFBC designates and the printing of memoranda relating
         thereto for the filing fee incident to, and the reasonable fees and
         disbursements of counsel to the Underwriters in connection with, the
         review by the National Association of Securities Dealers, Inc. of the
         Offered Securities, for any travel expenses of the Company's officers
         and employees and any other expenses of the Company in connection with
         attending or hosting meetings with prospective purchasers of the
         Offered Securities and for expenses incurred in distributing
         preliminary prospectuses and the Prospectus (including any amendments
         and supplements thereto) to the Underwriters.

                  (i) The Company will purchase U.S. government obligations (the
         "Pledged Securities") in an amount sufficient, upon receipt of
         scheduled principal and interest payments on such securities, to
         provide for payment in full of the first seven regularly scheduled
         interest payments due on the Notes. The Pledged Securities will be
         pledged by the Company to the Trustee for the benefit of holders of the
         Notes pursuant to a pledge agreement dated the Closing Date and between
         the Company and the Trustee (the "Pledge Agreement").

         6. Conditions of the Obligations of the Underwriters. The obligations
of the several Underwriters to purchase and pay for the Offered Securities on
the Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions precedent:

                  (a) The Underwriters shall have received a letter, dated the
         date of delivery thereof (which, if the Effective Time of the Initial
         Registration Statement is prior to the execution and delivery of this
         Agreement, shall be on or prior to the date of this Agreement or, if
         the Effective Time of the Initial Registration Statement is subsequent
         to the execution and delivery of this Agreement, shall be prior to the
         filing of the amendment or post-effective amendment to the registration
         statement to be filed shortly prior to such Effective Time), of Arthur
         Andersen LLP confirming that they are independent public accountants
         within the meaning of the Act and the applicable published Rules and
         Regulations thereunder and stating to the effect that:

                           (i) in their opinion the financial statements and
                  schedules, examined by them and included in the Registration
                  Statements comply as to form in all material respects with the
                  applicable accounting requirements of the Act and the related
                  published Rules and Regulations;

                           (ii) they have performed the procedures specified by
                  the American Institute of Certified Public Accountants for a
                  review of interim financial information as described in
                  Statement of Auditing Standards No. 71, Interim Financial
                  Information, on the unaudited financial statements included in
                  the Registration Statements;

                           (iii) on the basis of the review referred to in
                  clause (ii) above, a reading of the latest available interim
                  financial statements of the Company, inquiries of officials of
                  the Company who have responsibility for financial and
                  accounting matters and other specified procedures, nothing
                  came to their attention that caused them to believe that:

                                    (A) the unaudited financial statements
                           included in the Registration Statements do not comply
                           as to form in all material respects with the
                           applicable accounting requirements of the Act and the
                           related published Rules and Regulations or any
                           material modifications should be made to such
                           unaudited financial statements for them to be in
                           conformity with generally accepted accounting
                           principles;

                                    (B) at the date of the latest available
                           balance sheet read by such accountants, or at a
                           subsequent specified date not more than three
                           business days prior to the date of this Agreement,
                           there was any change in the capital stock or any
                           increase in short-term indebtedness or long-term debt
                           of the Company and its consolidated subsidiaries or,
                           at the date of the latest available balance sheet
                           read by such accountants, there was any decrease in
                           consolidated net assets, as compared with amounts
                           shown on the latest balance sheet included in the
                           Prospectus; or

                                    (C) for the period from the closing date of
                           the latest income statement included in the
                           Prospectus to the closing date of the latest
                           available income statement read by such accountants
                           there were any decreases, as compared with the
                           corresponding period of the previous year and with
                           the period of corresponding length ended the date of
                           the latest income statement included in the
                           Prospectus, in consolidated net sales, or net
                           operating income, or consolidated net income or in
                           EBITDA or the ratio of earnings to fixed charges,

                  except in all cases set forth in clauses (B) and (C) above for
                  changes, increases or decreases which the Prospectus discloses
                  have occurred or may occur and which are described in such
                  letter;

                           (iv) they have compared specified dollar amounts (or
                  percentages derived from such dollar amounts) and other
                  financial information contained in the Registration Statements
                  (in each case to the extent that such dollar amounts,
                  percentages and other financial information are derived from
                  the general accounting records of the Company and its
                  subsidiaries subject to the internal controls of the Company's
                  accounting system 


                                       7

                  or are derived directly from such records by analysis or
                  computation) with the results obtained from inquiries, a
                  reading of such general accounting records and other
                  procedures specified in such letter and have found such dollar
                  amounts, percentages and other financial information to be in
                  agreement with such results, except as otherwise specified in
                  such letter;

                           (v) they have:

                                    (A) read the unaudited adjusted and pro
                           forma summary balance sheet data as of December 31,
                           1997 and March 31, 1998;

                                    (B) inquired of certain officials of the
                           Company who have responsibility for financial and
                           accounting matters about (x) the basis for their
                           determination of the adjustments and (y) whether such
                           unaudited adjusted and pro forma financial
                           information comply as to form in all material
                           respects with the applicable accounting requirements
                           of the Act; and

                                    (C) confirmed the arithmetic accuracy of the
                           adjustments; and

                           (vi) based on the proceedings described in (v),
                  nothing came to their attention that caused them to believe
                  that the unaudited adjusted and pro forma financial
                  information contained in the Registration Statements do not
                  comply as to form in all material respects with the applicable
                  accounting requirements of the Act and that the adjustments
                  have not been properly applied to the historical amounts in
                  the compilation of that information.

         For purposes of this subsection, (i) if the Effective Time of the
         Initial Registration Statement is subsequent to the execution and
         delivery of this Agreement, "Registration Statements" shall mean the
         initial registration statement as proposed to be amended by the
         amendment or post-effective amendment to be filed shortly prior to its
         Effective Time, (ii) if the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement but
         the Effective Time of the Additional Registration is subsequent to such
         execution and delivery, "Registration Statements" shall mean the
         Initial Registration Statement and the additional registration
         statement as proposed to be filed or as proposed to be amended by the
         post-effective amendment to be filed shortly prior to its Effective
         Time, and (iii) "Prospectus" shall mean the prospectus included in the
         Registration Statements.

                  (b) If the Effective Time of the Initial Registration
         Statement is not prior to the execution and delivery of this Agreement,
         such Effective Time shall have occurred not later than 10:00 P.M., New
         York time, on the date of this Agreement or such later date as shall
         have been consented to by CSFBC. If the Effective Time of the
         Additional Registration Statement (if any) is not prior to the
         execution and delivery of this Agreement, such Effective Time shall
         have occurred not later than 10:00 P.M., New York time, on the date of
         this Agreement or, if earlier, the time the Prospectus is printed and
         distributed to any Underwriter, or shall have occurred at such later
         date as shall have been consented to by CSFBC. If the Effective Time of
         the Initial Registration Statement is prior to the execution and
         delivery of this Agreement, the Prospectus shall have been filed with
         the Commission in accordance with the Rules and Regulations and Section
         5(a) of this Agreement. Prior to the Closing Date, no stop order
         suspending the effectiveness of a Registration Statement shall have
         been issued and no proceedings for that purpose shall have been
         instituted or, to the knowledge of the Company or the Underwriters,
         shall be contemplated by the Commission.

                  (c) Subsequent to the execution and delivery of this
         Agreement, there shall not have occurred (i) any change, or any
         development or event involving a prospective change, in the condition
         (financial or other), business, properties or results of operations of
         the Company or its subsidiaries which, in the judgment of a majority in
         interest of the Underwriters, is material and adverse and makes it
         impractical or inadvisable to proceed with completion of the public
         offering or the sale of and payment for the Offered Securities; (ii)
         any downgrading in the rating of any debt securities of the Company by
         any "nationally recognized statistical rating organization" (as defined
         for purposes of Rule 436(g) under the Act), or any public announcement
         that any such organization has under surveillance or review its rating
         of any debt securities of the Company (other than an announcement with
         positive implications of a possible upgrading, and no implication of a
         possible downgrading, of such rating); (iii) any suspension or
         limitation of trading 


                                       8
<PAGE>


         in securities generally on the New York Stock Exchange, or any setting
         of minimum prices for trading on such exchange, or any suspension of
         trading of any securities of the Company on any exchange or in the
         over-the-counter market; (iv) any banking moratorium declared by U.S.
         Federal or New York authorities; or (v) any outbreak or escalation of
         major hostilities in which the United States is involved, any
         declaration of war by Congress or any other substantial national or
         international calamity or emergency if, in the judgment of a majority
         in interest of the Underwriters, the effect of any such outbreak,
         escalation, declaration, calamity or emergency makes it impractical or
         inadvisable to proceed with completion of the public offering or the
         sale of and payment for the Offered Securities.

                  (d) The Underwriters shall have received an opinion, dated
         such Closing Date, of Hale and Dorr LLP, counsel for the Company, to
         the effect that:

                           (i) The Company has been duly incorporated and is an
                  existing corporation in good standing under the laws of the
                  State of Delaware, with corporate power and authority to own
                  its properties and conduct its business as described in the
                  Prospectus; and the Company is duly qualified to do business
                  as a foreign corporation in good standing in all other
                  jurisdictions in which its ownership or lease of property or
                  the conduct of its business requires such qualification;

                           (ii) The Indenture has been duly authorized, executed
                  and delivered and has been duly qualified under the Trust
                  Indenture Act; the Pledge Agreement has been duly authorized,
                  executed and delivered; the Offered Securities have been duly
                  authorized, executed, authenticated, issued and delivered and
                  conform in all material respects to the description thereof
                  contained in the Prospectus; and the Indenture, the Pledge
                  Agreement and the Offered Securities constitute valid and
                  binding obligations of the Company enforceable in accordance
                  with their respective terms, subject to bankruptcy,
                  insolvency, fraudulent transfer, usery, reorganization,
                  moratorium and similar laws of general applicability relating
                  to or affecting creditors' rights and to general equity
                  principles;

                           (iii) There are no contracts, agreements or
                  understandings known to such counsel between the Company and
                  any person granting such person the right to require the
                  Company to file a registration statement under the Act with
                  respect to any securities of the Company owned or to be owned
                  by such person or to require the Company to include such
                  securities in the securities registered pursuant to the
                  Registration Statement or in any securities being registered
                  pursuant to any other registration statement filed by the
                  Company under the Act;

                           (iv) No consent, approval, authorization or order of,
                  or filing with, any governmental agency or body or any court
                  is required for the consummation of the transactions
                  contemplated by this Agreement in connection with the issuance
                  or sale of the Offered Securities by the Company, except such
                  as have been obtained and made under the Act and the Trust
                  Indenture Act and such as may be required under state
                  securities laws;

                           (v) The execution, delivery and performance of the
                  Indenture, the Pledge Agreement and this Agreement and the
                  issuance and sale of the Offered Securities and compliance
                  with the terms and provisions thereof will not result in a
                  breach or violation of any of the terms and provisions of, or
                  constitute a default under, any statute, any rule, regulation
                  or order of any governmental agency or body or any court
                  having jurisdiction over the Company or any subsidiary of the
                  Company or any of their properties, or any agreement or
                  instrument to which the Company or any such subsidiary is a
                  party or by which the Company or any such subsidiary is bound
                  or to which any of the properties of the Company or any such
                  subsidiary is subject, or the charter or by-laws of the
                  Company or any such subsidiary, and the Company has requisite
                  corporate power and authority to authorize, issue and sell the
                  Offered Securities as contemplated by this Agreement;

                           (vi) The Initial Registration Statement was declared
                  effective under the Act as of the date and time specified in
                  such opinion, the Additional Registration Statement (if any)
                  was filed and became effective under the Act as of the date
                  and time (if determinable) specified in such opinion, the
                  Prospectus either was filed with the Commission pursuant to
                  the subparagraph of Rule 424(b) specified in such opinion on
                  the date specified therein or was included in the Initial
                  Registration Statement or the

<PAGE>


                  Additional Registration Statement (as the case may be), and,
                  to the best of the knowledge of such counsel, no stop order
                  suspending the effectiveness of a Registration Statement or
                  any part thereof has been issued and no proceedings for that
                  purpose have been instituted or are pending or contemplated
                  under the Act, and each Registration Statement and the
                  Prospectus, and each amendment or supplement thereto, as of
                  their respective effective or issue dates, complied as to form
                  in all material respects with the requirements of the Act, the
                  Trust Indenture Act and the Rules and Regulations; such
                  counsel have no reason to believe that any part of a
                  Registration Statement or any amendment thereto, as of its
                  effective date or as of such Closing Date, contained any
                  untrue statement of a material fact or omitted to state any
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading or that the
                  Prospectus or any amendment or supplement thereto, as of its
                  issue date or as of such Closing Date, contained any untrue
                  statement of a material fact or omitted to state any material
                  fact necessary in order to make the statements therein, in the
                  light of the circumstances under which they were made, not
                  misleading; the descriptions in the Registration Statements
                  and Prospectus of statutes, legal and governmental proceedings
                  and contracts and other documents are accurate and fairly
                  present the information required to be shown; and such counsel
                  do not know of any legal or governmental proceedings required
                  to be described in a Registration Statement or the Prospectus
                  which are not described as required or of any contracts or
                  documents of a character required to be described in a
                  Registration Statement or the Prospectus or to be filed as
                  exhibits to a Registration Statement which are not described
                  and filed as required; it being understood that such counsel
                  need express no opinion as to the financial statements or
                  other financial data contained in the Registration Statements
                  or the Prospectus;

                           (vii) This Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (viii) Each subsidiary of the Company has been duly
                  incorporated and is an existing corporation in good standing
                  under the laws of the jurisdiction of its incorporation, with
                  power and authority (corporate and other) to own its
                  properties and conduct its business as described in the
                  Prospectus; and each subsidiary of the Company is duly
                  qualified to do business as a foreign corporation in good
                  standing in all other jurisdictions in which its ownership or
                  lease of property or the conduct of its business requires such
                  qualification; all of the issued and outstanding capital stock
                  of each subsidiary of the Company has been duly authorized and
                  validly issued and is fully paid and nonassessable; and the
                  capital stock of each subsidiary owned by the Company,
                  directly or through subsidiaries, is owned free from liens,
                  encumbrances and defects;

                           (ix) The Company is not and, after giving effect to
                  the offering and sale of the Offered Securities and the
                  application of the proceeds thereof as described in the
                  Prospectus, will not be an "investment company" as defined in
                  the Investment Company Act of 1940;

                           (x) The Company and its Subsidiaries are not, nor
                  will their respective businesses as described in the
                  Prospectus cause any of them to be in the future, subject to
                  the provisions of (x) the Communications Act or to any rules,
                  regulations and policies of the FCC related thereto or (y) any
                  state and local telecommunications laws, rules, regulations
                  and policies other than, in the case of certain of the
                  Company's subsidiaries, regulation by the FCC as a "common
                  carrier" under the Communications Act;

                           (xi) The statements in the Prospectus under the
                  captions "Regulation" and "Certain United States Federal 
                  Income Tax Consequences", insofar as they constitute summaries
                  of the legal matters, documents or proceedings referred to
                  therein, fairly present the information called for with
                  respect to such legal matters, documents and proceedings and
                  fairly summarize the matters referred to therein; and

                           (xii) The Pledge Agreement creates a valid security
                  interest in favor of the Trustee in all right, title and
                  interest of the Company in and to the Pledge Account and the
                  Pledged Securities.

                  (e) The Underwriters shall have received from Cravath, Swaine
         & Moore, counsel for the Underwriters, such opinion or opinions, dated
         such Closing Date, with respect to the 


                                       10
<PAGE>


         incorporation of the Company, the validity of the Offered Securities,
         the Registration Statements, the Prospectus and other related matters
         as the Representatives may require, and the Company shall have
         furnished to such counsel such documents as they reasonably request for
         the purpose of enabling them to pass upon such matters.

                  (f) The Underwriters shall have received a certificate, dated
         the Closing Date, of the President or any Vice President and a
         principal financial or accounting officer of the Company in which such
         officers, to the best of their knowledge after reasonable
         investigation, on behalf of the Company shall state that: the
         representations and warranties of the Company in this Agreement are
         true and correct; the Company has complied with all agreements and
         satisfied all conditions on its part to be performed or satisfied
         hereunder at or prior to the Closing Date; no stop order suspending the
         effectiveness of any Registration Statement has been issued and no
         proceedings for that purpose have been instituted or are contemplated
         by the Commission; the Additional Registration Statement (if any)
         satisfying the requirements of subparagraphs (1) and (3) of Rule 462(b)
         was filed pursuant to Rule 462(b), including payment of the applicable
         filing fee in accordance with Rule 111(a) or (b) under the Act, prior
         to the time the Prospectus was printed and distributed to any
         Underwriter; and, subsequent to the dates of the most recent financial
         statements in the Prospectus, there has been no material adverse
         change, nor any development or event involving a prospective material
         adverse change, in the condition (financial or other), business,
         properties or results of operations of the Company and its subsidiaries
         taken as a whole except as set forth in or contemplated by the
         Prospectus or as described in such certificate.

                  (g) The Underwriters shall have received a letter, dated the
         Closing Date, of Arthur Andersen LLP which meets the requirements of
         subsection (a) of this Section, except that the specified date referred
         to in such subsection will be a date not more than three business days
         prior to the Closing Date for the purposes of this subsection.

                  (h) The Equity Offering (as defined in the Prospectus) shall
         be simultaneously consummated on substantially the same terms as
         described in the Registration Statements.

The Company will furnish the Underwriters with such conformed copies of such
opinions, certificates, letters and documents as the Underwriters reasonably
request. CSFBC may in its sole discretion waive on behalf of the Underwriters
compliance with any conditions to the obligations of the Underwriters hereunder.

         7. Indemnification and Contribution. (a) The Company will indemnify and
hold harmless each Underwriter against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse each Underwriter for any legal or other expenses reasonably
incurred by such Underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action as such expenses are incurred;
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement in or omission or alleged
omission from any of such documents in reliance upon and in conformity with
written information furnished to the Company by any Underwriter through CSFBC
specifically for use therein, it being understood and agreed that the only such
information furnished by any Underwriter consists of the information described
as such in subsection (b) below.

         (b) Each Underwriter will severally and not jointly indemnify and hold
harmless the Company against any losses, claims, damages or liabilities to which
the Company may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, the Prospectus, or any
amendment or supplement thereto, or any related preliminary prospectus, or arise
out of or are based upon the omission or the alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through the CSFBC specifically for
use therein, and will reimburse any legal or other expenses reasonably incurred
by the Company in connection 


                                       11
<PAGE>


with investigating or defending any such loss, claim, damage, liability or
action as such expenses are incurred, it being understood and agreed that the
only such information furnished by any Underwriter consists of the following
information in the Prospectus furnished on behalf of each Underwriter: the last
paragraph at the bottom of the cover page concerning the terms of the offering
by the Underwriters, the legend concerning over-allotments and stabilizing on
the inside front cover page, the concession and reallowance figures appearing in
the third paragraph under the caption "Underwriting" and the information
contained in the fourth and sixth paragraphs under the caption "Underwriting".

         (c) Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above. In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement includes an unconditional release of
such indemnified party from all liability on any claims that are the subject
matter of such action.

         (d) If the indemnification provided for in this Section is unavailable
or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other from the offering of the Securities
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and the Underwriters on the other in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bear to
the total underwriting discounts and commissions received by the Underwriters.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any action or claim which is the subject of this
subsection (d). Notwithstanding the provisions of this subsection (d), no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations in
this subsection (d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

         (e) The obligations of the Company under this Section shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section shall be in addition to any liability which the
respective Underwriters may otherwise have and shall extend, upon the same terms
and conditions, to each director of the Company, to each officer of the Company
who has signed a Registration Statement and to each person, if any, who controls
the Company within the meaning of the Act.

         8. Default of Underwriters. If any Underwriter or Underwriters default
in their obligations to purchase Offered Securities hereunder and arrangements
satisfactory to CSFBC and the Company for the purchase of such Offered
Securities by other persons are not made within 36 hours after such default,
this Agreement will terminate without liability on the part of any
non-defaulting Underwriter or the Company, except as provided in Section 9. As
used in this Agreement, the term "Underwriter" includes any person substituted
for an Underwriter under this Section. Nothing herein will relieve a defaulting
Underwriter from liability for its default.

         9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Underwriter, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Offered Securities. If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the Offered Securities by the
Underwriters is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Underwriters pursuant to Section 7 shall
remain in effect. If the purchase of the Offered Securities by the Underwriters
is not consummated for any reason other than solely because of the termination
of this Agreement pursuant to Section 8 or the occurrence of any event specified
in clause (iii), (iv) or (v) of Section 6(c), the Company will reimburse the
Underwriters for all out-of-pocket expenses (including fees and disbursements of
counsel) reasonably incurred by them in connection with the offering of the
Offered Securities.

         10. Notices. All communications hereunder will be in writing and, if
sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed
to the Representatives c/o Credit Suisse First Boston Corporation, Eleven
Madison Avenue, New York, N.Y. 10010-3629, Attention: Investment Banking
Department-Transactions Advisory Group, or, if sent to the Company, will be
mailed, delivered or telegraphed and confirmed to it at Hale and Dorr LLP, 60
State Street, Boston, MA 02109, Attention: Alexander A. Bernhard, Esq.;
provided, however, that any notice to an Underwriter pursuant to Section 7 will
be mailed, delivered or telegraphed and confirmed to such Underwriter.

         11. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

         12. Representation of Underwriters. Any action under this Agreement
taken by CSFBC will be binding upon all the Underwriters.

         13. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

         14. Applicable Law. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York, without regard to
principles of conflicts of laws.

         The Company hereby submits to the non-exclusive jurisdiction of the
Federal and state courts in the Borough of Manhattan in The City of New York in
any suit or proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby.

CREDIT SUISSE FIRST BOSTON CORPORATION
WARBURG DILLON READ LLC,
  As Representatives of the Several Underwriters,
    c/o Credit Suisse First Boston Corporation,
         Eleven Madison Avenue,
           New York, N.Y. 10010-3629

Dear Sirs:

         1. Introductory. NorthEast Optic Network, Inc., a Delaware corporation
("Company"), proposes to issue and sell 4,000,000 shares of its Common Stock
("Securities") and the stockholders listed in Schedule A hereto ("Selling
Stockholders") propose severally to sell an aggregate of 1,500,000 outstanding
shares of the Securities (such 5,500,000 shares of Securities being hereinafter
referred to as the "Firm Securities"). The Company also proposes to sell to the
Underwriters, at the option of the Underwriters, an aggregate of not more than
825,000 additional shares of its Securities (the "Optional Securities"). The
Firm Securities and the Optional Securities are herein collectively called the
"Offered Securities". The Company and the Selling Stockholders hereby agree with
the several Underwriters named in Schedule B hereto ("Underwriters") as follows:

         2. Representations and Warranties of the Company and the Selling
Stockholders. (a) The Company represents and warrants to, and agrees with, the
several Underwriters that:

                  (i) A registration statement (No. 333-53441) relating to the
         Offered Securities, including a form of prospectus, has been filed with
         the Securities and Exchange Commission ("Commission") and either (A)
         has been declared effective under the Securities Act of 1933 ("Act")
         and is not proposed to be amended or (B) is proposed to be amended by
         amendment or post-effective amendment. If such registration statement
         (the "initial registration statement") has been declared effective,
         either (A) an additional registration statement (the "additional
         registration statement") relating to the Offered Securities may have
         been filed with the Commission pursuant to Rule 462(b) ("Rule 462(b)")
         under the Act and, if so filed, has become effective upon filing
         pursuant to such Rule and the Offered Securities all have been duly
         registered under the Act pursuant to the initial registration statement
         and, if applicable, the additional registration statement or (B) such
         an additional registration statement is proposed to be filed with the
         Commission pursuant to Rule 462(b) and will become effective upon
         filing pursuant to such Rule and upon such filing the Offered
         Securities will all have been duly registered under the Act pursuant to
         the initial registration statement and such additional registration
         statement. If the Company does not propose to amend the initial
         registration statement or if an additional registration statement has
         been filed and the Company does not propose to amend it, and if any
         post-effective amendment to either such registration statement has been
         filed with the Commission prior to the execution and delivery of this
         Agreement, the most recent amendment (if any) to each such registration
         statement has been declared effective by the Commission or has become
         effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the
         Act or, in the case of the additional registration statement, Rule
         462(b). For purposes of this Agreement, "Effective Time" with respect
         to the initial registration statement or, if filed prior to the
         execution and delivery of this Agreement, the additional registration
         statement means (A) if the Company has advised the Representatives that
         it does not propose to amend such registration statement, the date and
         time as of which such registration statement, or the most recent
         post-effective amendment thereto (if any) filed prior to the execution
         and delivery of this Agreement, was declared effective by the
         Commission or has


<PAGE>


         become effective upon filing pursuant to Rule 462(c), or (B) if the
         Company has advised the Representatives that it proposes to file an
         amendment or post-effective amendment to such registration statement,
         the date and time as of which such registration statement, as amended
         by such amendment or post-effective amendment, as the case may be, is
         declared effective by the Commission. If an additional registration
         statement has not been filed prior to the execution and delivery of
         this Agreement but the Company has advised the Representatives that it
         proposes to file one, "Effective Time" with respect to such additional
         registration statement means the date and time as of which such
         registration statement is filed and becomes effective pursuant to Rule
         462(b). "Effective Date" with respect to the initial registration
         statement or the additional registration statement (if any) means the
         date of the Effective Time thereof. The initial registration statement,
         as amended at its Effective Time, including all information contained
         in the additional registration statement (if any) and deemed to be a
         part of the initial registration statement as of the Effective Time of
         the additional registration statement pursuant to the General
         Instructions of the Form on which it is filed and including all
         information (if any) deemed to be a part of the initial registration
         statement as of its Effective Time pursuant to Rule 430A(b) ("Rule
         430A(b)") under the Act, is hereinafter referred to as the "Initial
         Registration Statement". The additional registration statement, as
         amended at its Effective Time, including the contents of the initial
         registration statement incorporated by reference therein and including
         all information (if any) deemed to be a part of the additional
         registration statement as of its Effective Time pursuant to Rule
         430A(b), is hereinafter referred to as the "Additional Registration
         Statement". The Initial Registration Statement and the Additional
         Registration are hereinafter referred to collectively as the
         "Registration Statements" and individually as a "Registration
         Statement". The form of prospectus relating to the Offered Securities,
         as first filed with the Commission pursuant to and in accordance with
         Rule 424(b) ("Rule 424(b)") under the Act or (if no such filing is
         required) as included in a Registration Statement, is hereinafter
         referred to as the "Prospectus". No document has been or will be
         prepared or distributed in reliance on Rule 434 under the Act.

                  (ii) If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement: (A)
         on the Effective Date of the Initial Registration Statement, the
         Initial Registration Statement conformed in all material respects to
         the requirements of the Act and the rules and regulations of the
         Commission ("Rules and Regulations") and did not include any untrue
         statement of a material fact or omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, (B) on the Effective Date of the Additional
         Registration Statement (if any), each Registration Statement conformed
         or will conform, in all material respects to the requirements of the
         Act and the Rules and Regulations and did not include, or will not
         include, any untrue statement of a material fact and did not omit, or
         will not omit, to state any material fact required to be stated therein
         or necessary to make the statements therein not misleading, and (C) on
         the date of this Agreement, the Initial Registration Statement and, if
         the Effective Time of the Additional Registration Statement is prior to
         the execution and delivery of this Agreement, the Additional
         Registration Statement each conforms, and at the time of filing of the
         Prospectus pursuant to Rule 424(b) or (if no such filing is required)
         at the Effective Date of the Additional Registration Statement in which
         the Prospectus is included, each Registration Statement and the
         Prospectus will conform, in all material respects to the requirements
         of the Act and the Rules and Regulations, and neither of such documents
         includes, or will include, any untrue statement of a material fact or
         omits, or will omit, to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading. If
         the Effective Time of the Initial Registration Statement is subsequent
         to the execution and delivery of this Agreement: on the Effective Date
         of the Initial Registration Statement, the Initial Registration
         Statement and the Prospectus will conform in all material respects to
         the requirements of the Act and the Rules and Regulations, neither of
         such documents will include any untrue statement of a material fact or
         will omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading, and no
         Additional Registration Statement has been or will be filed. The two
         preceding sentences do not apply to statements in or omissions from a
         Registration Statement or the Prospectus based upon written information
         furnished to the Company by any Underwriter through the Representatives
         specifically for use therein, it being understood and agreed that the
         only such information is that described as such in Section 7(c) hereof.

                  (iii) The Company has been duly incorporated and is an
         existing corporation in good standing under the laws of the State of
         Delaware, with power and authority (corporate and other) to own its
         properties and conduct its business as described in the Prospectus; and
         the Company is duly qualified to do business as a foreign corporation
         in good standing in all other jurisdictions in which its ownership or
         lease of property or the conduct of its business requires such
         qualification, except where the failure to be so qualified or in good
         standing would not have, individually or in


                                       2
<PAGE>


         the aggregate, a material adverse effect on the condition (financial or
         other), business, properties or results of operations of the Company
         and its subsidiaries, taken as a whole (a "Material Adverse Effect").

                  (iv) Each subsidiary of the Company has been duly incorporated
         and is an existing corporation in good standing under the laws of the
         jurisdiction of its incorporation, with power and authority (corporate
         and other) to own its properties and conduct its business as described
         in the Prospectus; and each subsidiary of the Company is duly qualified
         to do business as a foreign corporation in good standing in all other
         jurisdictions in which its ownership or lease of property or the
         conduct of its business requires such qualification in each case except
         as would not have a Material Adverse Effect; all of the issued and
         outstanding capital stock of each subsidiary of the Company has been
         duly authorized and validly issued and is fully paid and nonassessable;
         and the capital stock of each subsidiary owned by the Company, directly
         or through subsidiaries, is owned free from liens, encumbrances and
         defects except as otherwise described in the Prospectus.

                  (v) The Offered Securities and all other outstanding shares of
         capital stock of the Company have been duly authorized; all outstanding
         shares of capital stock of the Company are, and, when the Offered
         Securities have been delivered and paid for in accordance with this
         Agreement on each Closing Date (as defined below), such Offered
         Securities will have been, validly issued, fully paid and nonassessable
         and conform to the description thereof contained in the Prospectus; and
         the stockholders of the Company have no preemptive rights with respect
         to the Securities.

                  (vi) Except as disclosed in the Prospectus, there are no
         contracts, agreements or understandings between the Company and any
         person that would give rise to a valid claim against the Company or any
         Underwriter for a brokerage commission, finder's fee or other like
         payment in connection with this offering.

                  (vii) Except as described in the Prospectus, there are no
         contracts, agreements or understandings between the Company and any
         person granting such person the right to require the Company to file a
         registration statement under the Act with respect to any securities of
         the Company owned or to be owned by such person or to require the
         Company to include such securities in the securities registered
         pursuant to a Registration Statement or in any securities being
         registered pursuant to any other registration statement filed by the
         Company under the Act.

                  (viii) The Securities have been approved for listing subject
         to notice of issuance on the Nasdaq Stock Market's National Market.

                  (ix) No consent, approval, authorization, or order of, or
         filing with, any governmental agency or body or any court is required
         to be obtained or made by the Company for the consummation of the
         transactions contemplated by this Agreement in connection with the sale
         of the Offered Securities, except such as have been obtained and made
         under the Act and the Securities Exchange Act of 1934, as amended (the
         "Exchange Act") and such as may be required under state or foreign
         securities laws.

                  (x) The execution, delivery and performance of this Agreement,
         and the consummation of the transactions herein contemplated will not
         result in a breach or violation of any of the terms and provisions of,
         or constitute a default under, any existing statute, any existing rule,
         regulation or order naming the Company or any Selling Stockholder of
         any governmental agency or body or any court, domestic or foreign,
         having jurisdiction over the Company or any subsidiary of the Company
         or any of their properties, or any agreement or instrument to which the
         Company or any such subsidiary is a party or by which the Company or
         any such subsidiary is bound or to which any of the properties of the
         Company or any such subsidiary is subject (except such as would not
         have a material adverse effect), or the charter or by-laws of the
         Company or any such subsidiary.

                  (xi) This Agreement has been duly authorized, executed and
         delivered by the Company.

                  (xii) Except as disclosed in the Prospectus, the Company and
         its subsidiaries have good and marketable title to all real properties
         and all other properties and assets owned by them, in each case free
         from liens, encumbrances and defects that would materially affect the
         value thereof or materially interfere with the use made or to be made
         thereof by them; except as disclosed in the Prospectus, the Company and
         its subsidiaries hold any leased real or personal property under valid
         and enforceable leases with no exceptions that would materially
         interfere with the use made or to be made thereof by them; and except
         as disclosed in the Prospectus, the Company and its


                                       3
<PAGE>


         Subsidiaries hold easements and indefeasible rights of use under valid
         and enforceable agreements with no exceptions that would materially
         interfere with the use made or to be made thereof by them.

                  (xiii) The Company and its subsidiaries possess adequate
         certificates, authorities or permits issued by appropriate governmental
         agencies or bodies necessary to conduct the business now operated by
         them (except where the failure to possess the same would not
         individually or in the aggregate have a Material Adverse Effect) and
         have not received any notice of proceedings relating to the revocation
         or modification of any such certificate, authority or permit that, if
         determined adversely to the Company or any of its subsidiaries, could
         individually or in the aggregate reasonably be expected to have a
         Material Adverse Effect.

                  (xiv) No labor dispute with the employees of the Company or
         any subsidiary exists or, to the knowledge of the Company, is imminent
         that might have a material adverse effect on the Company and its
         subsidiaries taken as a whole.

                  (xv) The Company and its subsidiaries own, possess or can
         acquire on reasonable terms, adequate trademarks, trade names and other
         rights to inventions, know-how, patents, copyrights, confidential
         information and other intellectual property (collectively,
         "intellectual property rights") necessary to conduct the business now
         operated by them, or presently employed by them, and have not received
         any notice of infringement of or conflict with asserted rights of
         others with respect to any intellectual property rights that, if
         determined adversely to the Company or any of its subsidiaries, could
         individually or in the aggregate reasonably be expected to have a
         Material Adverse Effect.

                  (xvi) Except as disclosed in the Prospectus, neither the
         Company nor any of its subsidiaries is in violation of any statute, any
         rule, regulation, decision or order of any governmental agency or body
         or any court, domestic or foreign, relating to the use, disposal or
         release of hazardous or toxic substances or relating to the protection
         or restoration of the environment or human exposure to hazardous or
         toxic substances (collectively, "environmental laws"), owns or operates
         any real property contaminated with any substance that is subject to
         any environmental laws, is liable for any off-site disposal or
         contamination pursuant to any environmental laws, or is subject to any
         claim relating to any environmental laws, which violation,
         contamination, liability or claim could individually or in the
         aggregate reasonably be expected to have a Material Adverse Effect and
         the Company is not aware of any pending investigation which might lead
         to such a claim.

                  (xvii) Except as disclosed in the Prospectus, there are no
         pending actions, suits or proceedings against or affecting the Company,
         any of its subsidiaries or any of their respective properties that, if
         determined adversely to the Company or any of its subsidiaries, would
         individually or in the aggregate have a Material Adverse Effect would
         materially and adversely affect the ability of the Company to perform
         its obligations under this Agreement, or which are otherwise material
         in the context of the sale of the Offered Securities; and no such
         actions, suits or proceedings are threatened or, to the Company's
         knowledge, contemplated.

                  (xviii) The financial statements included in each Registration
         Statement and the Prospectus present fairly the financial position of
         the Company and its consolidated subsidiaries as of the dates shown and
         their results of operations and cash flows for the periods shown, and
         such financial statements have been prepared in conformity with the
         generally accepted accounting principles in the United States applied
         on a consistent basis and the assumptions used in preparing the pro
         forma financial information included in each Registration Statement and
         the Prospectus provide a reasonable basis for presenting the
         significant effects directly attributable to the transactions or events
         described therein, the related pro forma adjustments give appropriate
         effect to those assumptions, and the pro forma columns therein reflect
         the proper application of those adjustments to the corresponding
         historical financial statement amounts.

                  (xix) Except as disclosed in the Prospectus, since the date of
         the latest audited financial statements included in the Prospectus
         there has been no material adverse change, nor any development or event
         involving a prospective material adverse change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and its subsidiaries taken as a whole, and, except as
         disclosed in or contemplated by the Prospectus, there has been no
         dividend or distribution of any kind declared, paid or made by the
         Company on any class of its capital stock.

                  (xx) The Company is not and, after giving effect to the
         offering and sale of the Offered Securities and the application of the
         proceeds thereof as described in the Prospectus, will not be an
         "investment company" as defined in the Investment Company Act of 1940.

                  (xxi) Neither the Company nor any of its affiliates does
         business with the government of Cuba or with any person or affiliate
         located in Cuba within the meaning of Section 517.075, Florida Statutes
         and the Company agrees to comply with such Section if prior to the
         completion of the distribution of the Offered Securities it commences
         doing such business.

                   (xxii) Except as disclosed in the Prospectus, neither the
         Company nor any of its subsidiaries are currently, nor will the conduct
         of their business as described in Prospectus cause any of them to be in
         the future, subject to the provisions of the Communications Act of
         1934, as amended by the Telecommunications Act of 1996 (the
         "Communications Act") or to any rules, regulations and policies of the
         Federal Communications Commission (the "FCC") related thereto.

                  (xxiii) The Company and its subsidiaries are in compliance in
         all material respects with all federal, state and local
         telecommunications laws, rules, regulations and policies to which they
         are subject, including, with respect to subsidiaries, the
         Communications Act and the related rules, regulations and policies of
         the FCC.

                  (b) Each Selling Stockholder severally represents and warrants
to, and agrees with, the several Underwriters that:

                  (i) Such Selling Stockholder has and on the First Closing Date
         (hereinafter defined) will have valid and unencumbered title to the
         Offered Securities to be delivered by such Selling Stockholder on such
         Closing Date and full right, power and authority to enter into this
         Agreement and to sell, assign, transfer and deliver the Offered
         Securities to be delivered by such Selling Stockholder on such Closing
         Date hereunder; and upon the delivery of and payment for the Offered
         Securities on the First Closing Date, the several Underwriters will
         acquire valid and unencumbered title to the Offered Securities to be
         delivered by such Selling Stockholder on such Closing Date.

                  (ii) If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement: (A)
         on the Effective Date of the Initial Registration Statement, the
         Initial Registration Statement conformed in all material respects to
         the requirements of the Act and the Rules and Regulations and did not
         include any untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, (B) on the Effective Date of the
         Additional Registration Statement (if any), each Registration Statement
         conformed, or will conform, in all material respects to the
         requirements of the Act and the Rules and Regulations did not include,
         or will not include, any untrue statement of a material fact and did
         not omit, or will not omit, to state any material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, and (C) on the date of this Agreement, the Initial
         Registration Statement and, if the Effective Time of the Additional
         Registration Statement is prior to the execution and delivery of this
         Agreement, the Additional Registration Statement each conforms, and at
         the time of filing of the Prospectus pursuant to Rule 424(b) or (if no
         such filing is required) at the Effective Date of the Additional
         Registration Statement in which the Prospectus is included, each
         Registration Statement and the Prospectus will conform, in all material
         respects to the requirements of the Act and the Rules and Regulations,
         and neither of such documents includes, or will include, any untrue
         statement of a material fact or omits, or will omit, to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading. If the Effective Time of the Initial
         Registration Statement is subsequent to the execution and delivery of
         this Agreement: on the Effective Date of the Initial Registration
         Statement, the Initial Registration Statement and the Prospectus will
         conform in all material respects to the requirements of the Act and the
         Rules and Regulations, neither of such documents will include any
         untrue statement of a material fact or will omit to state any material
         fact required to be stated therein or necessary to make the statements
         therein not misleading. The two preceding sentences do not apply to
         statements in or omissions from a Registration Statement or the
         Prospectus based upon written information furnished to the Company by
         any Underwriter through the Representatives specifically for use
         therein, it being understood and agreed that the only such information
         is that described as such in Section 7(c).

                  (iii) Except as disclosed in the Prospectus, there are no
         contracts, agreements or understandings between such Selling
         Stockholder and any person that would give rise to a valid


                                       5

         claim against such Selling Stockholder or any Underwriter for a
         brokerage commission, finder's fee or other like payment in connection
         with this offering.

         3. Purchase, Sale and Delivery of Offered Securities. On the basis of
the representations, warranties and agreements herein contained, but subject to
the terms and conditions herein set forth, the Company and each Selling
Stockholder agree, severally and not jointly, to sell to each Underwriter, and
each Underwriter agrees, severally and not jointly, to purchase from the Company
and each Selling Stockholder, at a purchase price of $             per share,
that number of Firm Securities (rounded up or down, as determined by Credit
Suisse First Boston Corporation ("CSFBC") in its discretion, in order to avoid
fractions) obtained by multiplying                      Firm Securities in the 
case of the Company and the number of Firm Securities set forth opposite the
name of such Selling Stockholder in Schedule A hereto, in the case of a Selling
Stockholder, in each case by a fraction the numerator of which is the number of
Firm Securities set forth opposite the name of such Underwriter in Schedule B
hereto and the denominator of which is the total number of Firm Securities.

         Certificates in negotiable form for the Offered Securities to be sold
by the Selling Stockholders hereunder have been placed in custody, for delivery
under this Agreement, under Custody Agreements made with the Company, as
custodian ("Custodian"). Each Selling Stockholder agrees that the shares
represented by the certificates held in custody for the Selling Stockholders
under such Custody Agreements are subject to the interests of the Underwriters
hereunder, that the arrangements made by the Selling Stockholders for such
custody are to that extent irrevocable, and that the obligations of the Selling
Stockholders hereunder shall not be terminated by operation of law or the
occurrence of any other event. If such event should occur before the delivery of
the Offered Securities hereunder, certificates for such Offered Securities shall
be delivered by the Custodian in accordance with the terms and conditions of
this Agreement as if such event had not occurred, regardless of whether or not
the Custodian shall have received notice of such event.

         The Company and the Custodian will deliver the Firm Securities to the
Representatives for the accounts of the Underwriters, against payment of the
purchase price in Federal (same day) funds by official bank check or checks or
wire transfer to an account at a bank acceptable to CSFBC drawn to the order of
the Company in the case of shares of Firm Securities being sold by the Company
and each of the Selling Stockholders in the case of Firm Securities being sold
by the Selling Stockholders, at the office of Cravath, Swaine & Moore, 825
Eighth Avenue, New York, New York, at 10:00 New York time, on             , 1998
or at such other time not later than seven full business days thereafter as
CSFBC and the Company determine, such time being herein referred to as the
"First Closing Date". The certificates for the Firm Securities so to be
delivered will be in definitive form, in such denominations and registered in
such names as CSFBC requests and will be made available for checking and
packaging at the office of Cravath, Swaine & Moore at least 24 hours prior to
the First Closing Date.

         In addition, upon written notice from CSFBC given to the Company from
time to time not more than 30 days subsequent to the date of the Prospectus, the
Underwriters may purchase all or less than all of the Optional Securities at the
purchase price per Security to be paid for the Firm Securities. Such Optional
Securities shall be purchased from the Company for the account of each
Underwriter in the same proportion as the number of Firm Securities set forth
opposite such Underwriter's name bears to the total number of Firm Securities
(subject to adjustment by CSFBC to eliminate fractions) and may be purchased by
the Underwriters only for the purpose of covering over-allotments made in
connection with the sale of the Firm Securities. No Optional Securities shall be
sold or delivered unless the Firm Securities previously have been, or
simultaneously are, sold and delivered. The right to purchase the Optional
Securities or any portion thereof may be exercised from time to time and to the
extent not previously exercised may be surrendered and terminated at any time
upon notice by CSFBC to the Company.

         Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase Optional Securities is given. The Company will deliver the
Optional Securities being purchased on each Optional Closing Date to the
Representatives for the accounts of the several Underwriters, against payment of
the purchase price therefor in Federal (same day) funds by official bank check
or checks or wire transfer to an account at a bank acceptable to CSFBC drawn to
the order of the Company, at the above office of Cravath, Swaine & Moore. The
certificates for the Optional Securities being purchased on each Optional
Closing Date will be in definitive form, in such denominations and registered in
such names as CSFBC requests upon reasonable notice prior to such Optional
Closing Date and will be made available for checking and packaging at the office
of Cravath, Swaine & Moore at a reasonable time in advance of such Optional
Closing Date.

         4. Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Offered Securities for sale to the public as
set forth in the Prospectus.

         5. Certain Agreements of the Company and the Selling Stockholders. The
Company agrees with the several Underwriters and the Selling Stockholders that:

                  (a) If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement, the
         Company will file the Prospectus with the Commission pursuant to and in
         accordance with subparagraph (1) (or, if applicable and if consented to
         by CSFBC, subparagraph (4)) of Rule 424(b) not later than the earlier
         of (A) the second business day following the execution and delivery of
         this Agreement or (B) the fifteenth business day after the Effective
         Date of the Initial Registration Statement. The Company will advise
         CSFBC and the Selling Stockholders promptly and the Selling
         Stockholders of any such filing pursuant to Rule 424(b). If the
         Effective Time of the Initial Registration Statement is prior to the
         execution and delivery of this Agreement and an additional registration
         statement is necessary to register a portion of the Offered Securities
         under the Act but the Effective Time thereof has not occurred as of
         such execution and delivery, the Company will file the additional
         registration statement or, if filed, will file a post-effective
         amendment thereto with the Commission pursuant to and in accordance
         with Rule 462(b) on or prior to 10:00 p.m., New York time, on the date
         of this Agreement or, if earlier, on or prior to the time the
         Prospectus is printed and distributed to any Underwriter, or will make
         such filing at such later date as shall have been consented to by
         CSFBC.

                  (b) The Company will advise CSFBC and the Selling Stockholders
         promptly of any proposal to amend or supplement the initial or any
         additional registration statement as filed or the related prospectus or
         the Initial Registration Statement, the Additional Registration
         Statement (if any) or the Prospectus and will not effect such amendment
         or supplementation without CSFBC's consent; and the Company will also
         advise CSFBC and the Selling Stockholders promptly of the effectiveness
         of each Registration Statement (if its Effective Time is subsequent to
         the execution and delivery of this Agreement) and of any amendment or
         supplementation of a Registration Statement or the Prospectus and of
         the institution by the Commission of any stop order proceedings in
         respect of a Registration Statement and will use its best efforts to
         prevent the issuance of any such stop order and to obtain as soon as
         possible its lifting, if issued.

                  (c) If, at any time when a prospectus relating to the Offered
         Securities is required to be delivered under the Act in connection with
         sales by any Underwriter or dealer, any event occurs as a result of
         which the Prospectus as then amended or supplemented would include an
         untrue statement of a material fact or omit to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or if it is
         necessary at any time to amend the Prospectus to comply with the Act,
         the Company will promptly notify CSFBC and the Selling Stockholders of
         such event and will promptly prepare and file with the Commission, at
         its own expense, an amendment or supplement which will correct such
         statement or omission or an amendment which will effect such
         compliance. Neither CSFBC's consent to, nor the Underwriters' delivery
         of, any such amendment or supplement shall constitute a waiver of any
         of the conditions set forth in Section 6.

                  (d) As soon as practicable, but not later than the
         Availability Date (as defined below), the Company will make generally
         available to its securityholders an earnings statement covering a
         period of at least 12 months beginning after the Effective Date of the
         Initial Registration Statement (or, if later, the Effective Date of the
         Additional Registration Statement) which will satisfy the provisions of
         Section 11(a) of the Act. For the purpose of the preceding sentence,
         "Availability Date" means the 45th day after the end of the fourth
         fiscal quarter following the fiscal quarter that includes such
         Effective Date, except that, if such fourth fiscal quarter is the last
         quarter of the Company's fiscal year, "Availability Date" means the
         90th day after the end of such fourth fiscal quarter.

                  (e) The Company will furnish to the Representatives copies of
         each Registration Statement (three of which will be signed and will
         include all exhibits), each related preliminary prospectus, and, so
         long as a prospectus relating to the Offered Securities is required to
         be delivered under the Act in connection with sales by any Underwriter
         or dealer, the Prospectus and all amendments and supplements to such
         documents, in each case in such quantities as CSFBC requests. The
         Prospectus shall be so furnished on or prior to 5:00 p.m., New York
         time, on the business day following the later of the execution and
         delivery of this Agreement or the Effective Time of the Initial
         Registration Statement. All other such documents shall be so furnished
         as soon


                                       7
<PAGE>


         as available. The Company will pay the expenses of printing and
         distributing to the Underwriters all such documents.

                  (f) The Company will arrange for the qualification of the
         Offered Securities for sale under the laws of such jurisdictions in the
         United States and Canada as CSFBC designates and will continue such
         qualifications in effect so long as required for the distribution of
         the Offered Securities; provided, however, that in connection therewith
         the Company shall not be required to qualify as a foreign corporation
         or to file a general consent to service of process in any jurisdiction.

                  (g) During the period of 3 years hereafter, the Company will
         furnish to the Representatives and, upon request, to each of the other
         Underwriters, as soon as practicable after the end of each fiscal year,
         a copy of its annual report to stockholders for such year; and the
         Company will furnish to the Representatives (i) as soon as available, a
         copy of each report and any definitive proxy statement of the Company
         filed with the Commission under the Securities Exchange Act of 1934 or
         mailed to stockholders, and (ii) from time to time, such other
         information concerning the Company as CSFBC may reasonably request,
         which such other information shall be kept confidential by the
         Underwriters.

                  (h) For a period of 180 days after the date of the initial
         public offering of the Offered Securities, the Company will not offer,
         sell, contract to sell, pledge or otherwise dispose of, directly or
         indirectly, or file with the Commission a registration statement under
         the Act (Other than on Form S-8 and relating to resales of securities
         as described in the general instructions to Form S-8) relating to, any
         additional shares of its Securities or securities convertible into or
         exchangeable or exercisable for any shares of its Securities, or
         publicly disclose the intention to make any such offer, sale, pledge,
         disposition or filing, without the prior written consent of CSFBC,
         except grants of stock or options therefor to employees pursuant to the
         terms of an incentive plan in effect on the date hereof, issuances of
         Securities pursuant to the exercise of such options or the exercise of
         any other employee stock options outstanding on the date hereof or
         issuances of Securities pursuant to the Company's dividend reinvestment
         plan.

                  (i) The Company and each Selling Stockholder agree with the
         several Underwriters that the Company and such Selling Stockholder will
         pay all expenses incident to the performance of the obligations of the
         Company and such Selling Stockholder, as the case may be, under this
         Agreement, for any filing fees and other expenses (including fees and
         disbursements of counsel) in connection with qualification of the
         Offered Securities for sale under the laws of such jurisdictions in the
         U.S. as CSFBC designates and the printing of memoranda relating
         thereto, for the filing fee incident to, and the reasonable fees and
         disbursements of counsel to the Underwriters in connection with, the
         review by the National Association of Securities Dealers, Inc. of the
         Offered Securities, for any travel expenses of the Company's officers
         and employees and any other expenses of the Company in connection with
         attending or hosting meetings with prospective purchasers of the
         Offered Securities, for any transfer taxes on the sale by the Selling
         Stockholders of the Offered Securities to the Underwriters and for
         expenses incurred in distributing preliminary prospectuses and the
         Prospectus (including any amendments and supplements thereto) to the
         Underwriters.

                  (j) Each Selling Stockholder agrees severally and not jointly
         to deliver to CSFBC, attention: Transactions Advisory Group on or prior
         to the First Closing Date a properly completed and executed United
         States Treasury Department Form W-9 (or other applicable form or
         statement specified by Treasury Department regulations in lieu
         thereof).

                  (k) Each Selling Stockholder agrees, for a period of 180 days
         after the date of the initial public offering of the Offered
         Securities, not to offer, sell, contract to sell, pledge or otherwise
         dispose of, directly or indirectly, any additional shares of the
         Securities of the Company or securities convertible into or
         exchangeable or exercisable for any shares of Securities, or publicly
         disclose the intention to make any such offer, sale, pledge or
         disposition, without the prior written consent of CSFBC, other than
         transfers to affiliated entities.

         6. Conditions of the Obligations of the Underwriters. The obligations
of the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company and the Selling Stockholders herein, to

         public accountants within the meaning of the Act and the applicable
         published Rules and Regulations thereunder and stating to the effect
         that:

                           (i) in their opinion the financial statements and
                  schedules examined by them and included in the Registration
                  Statements comply as to form in all material respects with the
                  applicable accounting requirements of the Act and the related
                  published Rules and Regulations;

                           (ii) they have performed the procedures specified by
                  the American Institute of Certified Public Accountants for a

                  clause (ii) above, a reading of the latest available interim
                  financial statements of the Company, inquiries of officials of
                  the Company who have responsibility for financial and
                  accounting matters and other specified procedures, nothing
                  came to their attention that caused them to believe that:

                                    (A) the unaudited financial statements
                           included in the Registration Statements do not comply
                           as to form in all material respects with the
                           applicable accounting requirements of the Act and the
                           related published Rules and Regulations or any
                           material modifications should be made to such
                           unaudited financial statements for them to be in
                           conformity with generally accepted accounting
                           principles;

                           business days prior to the date of this Agreement,
                           there was any change in the capital stock or any
                           increase in short-term indebtedness or long-term debt
                           of the Company and its consolidated subsidiaries or,

                           read by such accountants, there was any decrease in
                           consolidated net assets, as compared with amounts
                           shown on the latest balance sheet included in the
                           Prospectus; or

                                    (C) for the period from the closing date of
                           the latest income statement included in the
                           Prospectus to the closing date of the latest
                           available income statement read by such accountants
                           there were any decreases, as compared with the
                           corresponding period of the previous year and with
                           the period of corresponding length ended the date of
                           the latest income statement included in the
                           Prospectus, in consolidated net sales or net
                           operating income in the total or per share amounts of
                           consolidated income before extraordinary items or net
                           income or in EBITDA or the ratio of earnings to fixed
                           charges;

                  except in all cases set forth in clauses (B) and (C) above for
                  changes, increases or decreases which the Prospectus discloses
                  have occurred or may occur or which are described in such
                  letter;

                           (iv) they have compared specified dollar amounts (or
                  percentages derived from such dollar amounts) and other
                  financial information contained in the Registration Statements
                  (in each case to the extent that such dollar amounts,
                  percentages and other financial information are derived from
                  the general accounting records of the Company and its
                  subsidiaries subject to the internal controls of the Company's
                  accounting system or are derived directly from such records by
                  analysis or computation) with the results obtained from
                  inquiries, a reading of such general accounting records and
                  other procedures specified in such letter and have found such
                  dollar amounts, percentages and

                  other financial information to be in agreement with such
                  results, except as otherwise specified in such letter;

                           (v) they have:

                                    (A) read the unaudited adjusted and pro
                           forma summary balance sheet data as of December 31,
                           1997 and March 31, 1998;

                                    (B) inquired of certain officials of the
                           Company who have responsibility for financial and
                           accounting matters about (x) the basis for their
                           determination of the adjustments and (y) whether such
                           unaudited adjusted and pro forma financial
                           information comply as to form in all material
                           respects with the applicable accounting requirements
                           of the Act; and

                                    (C)  confirmed the arithmetic accuracy of
                           the adjustments; and

                           (vi) based on the proceedings described in (v),
                  nothing came to their attention that caused them to believe
                  that the unaudited adjusted and pro forma financial
                  information contained in the Registration Statements do not
                  comply as to form in all material respects with the applicable
                  accounting requirements of the Act and that the adjustments
                  have not been properly applied to the historical amounts in
                  the compilation of that information.

         For purposes of this subsection, (i) if the Effective Time of the
         Initial Registration Statements is subsequent to the execution and
         delivery of this Agreement, "Registration Statements" shall mean the
         initial registration statement as proposed to be amended by the
         amendment or post-effective amendment to be filed shortly prior to its
         Effective Time, (ii) if the Effective Time of the Initial Registration
         Statements is prior to the execution and delivery of this Agreement but
         the Effective Time of the Additional Registration Statement is
         subsequent to such execution and delivery, "Registration Statements"
         shall mean the Initial Registration Statement and the additional
         registration statement as proposed to be filed or as proposed to be
         amended by the post-effective amendment to be filed shortly prior to
         its Effective Time, and (iii) "Prospectus" shall mean the prospectus
         included in the Registration Statements.

                  (b) If the Effective Time of the Initial Registration
         Statement is not prior to the execution and delivery of this Agreement,
         such Effective Time shall have occurred not later than 10:00 p.m., New
         York time, on the date of this Agreement or such later date as shall
         have been consented to by CSFBC. If the Effective Time of the
         Additional Registration Statement (if any) is not prior to the
         execution and delivery of this Agreement, such Effective Time shall
         have occurred not later than 10:00 p.m., New York time, on the date of
         this Agreement or, if earlier, the time the Prospectus is printed and
         distributed to any Underwriter, or shall have occurred at such later
         date as shall have been consented to by CSFBC. If the Effective Time of
         the Initial Registration Statement is prior to the execution and
         delivery of this Agreement, the Prospectus shall have been filed with
         the Commission in accordance with the Rules and Regulations and Section
         5(a) of this Agreement. Prior to such Closing Date, no stop order
         suspending the effectiveness of a Registration Statement shall have
         been issued and no proceedings for that purpose shall have been
         instituted or, to the knowledge of any Selling Stockholder, the Company
         or the Representatives, shall be contemplated by the Commission.

                  (c) Subsequent to the execution and delivery of this
         Agreement, there shall not have occurred (i) any change, or any
         development or event involving a prospective change, in the condition
         (financial or other), business, properties or results of operations of
         the Company or its subsidiaries which, in the judgment of a majority in
         interest of the Underwriters including the Representatives, is material
         and adverse and makes it impractical or inadvisable to proceed with
         completion of the public offering or the sale of and payment for the
         Offered Securities; (ii) any downgrading in the rating of any debt
         securities of the Company by any "nationally recognized statistical
         rating organization" (as defined for purposes of Rule 436(g) under the
         Act), or any public announcement that any such organization has under
         surveillance or review its rating of any debt securities of the Company
         (other than an announcement with positive implications of a possible
         upgrading, and no implication of a possible downgrading, of such
         rating); (iii) any suspension or limitation of trading in securities
         generally on the New York Stock Exchange, or any setting of minimum
         prices for trading on such exchange, or any suspension of trading of
         any securities of the Company on any exchange or in the
         over-the-counter market; (iv) any banking moratorium declared by U.S.
         Federal or New York authorities; or (v) any outbreak or escalation


                                       10

         of major hostilities in which the United States is involved, any
         declaration of war by Congress or any other substantial national or
         international calamity or emergency if, in the judgment of a majority
         in interest of the Underwriters including the Representatives, the
         effect of any such outbreak, escalation, declaration, calamity or
         emergency makes it impractical or inadvisable to proceed with
         completion of the public offering or the sale of and payment for the
         Offered Securities.

                  (d) The Representatives and the Selling Stockholders shall
         have received an opinion, dated such Closing Date, of Hale and Dorr
         LLP, counsel for the Company, to the effect that:

                           (i) The Company has been duly incorporated and is an
                  existing corporation in good standing under the laws of the
                  State of Delaware, with corporate power and authority to own
                  its properties and conduct its business as described in the
                  Prospectus; and the Company is duly qualified to do business
                  as a foreign corporation in good standing in all other
                  jurisdictions in which its ownership or lease of property or
                  the conduct of its business requires such qualification;

                           (ii) The Firm Securities delivered on such Closing
                  Date and all other outstanding shares of the Common Stock of
                  the Company have been duly authorized; all outstanding shares
                  of capital stock of the Company are, and, when the Offered
                  Securities have been delivered and paid for in accordance with
                  this Agreement on each Closing Date (as defined below), such
                  Offered Securities will have been, validly issued, are fully
                  paid and nonassessable and do conform in all material respects
                  to the description thereof contained in the Prospectus; and
                  the stockholders of the Company have and will have no
                  preemptive rights with respect to the Securities;

                           (iii) Except as described in the Prospectus, there
                  are no contracts, agreements or understandings between the
                  Company and any person granting such person the right to
                  require the Company to file a registration statement under the
                  Act with respect to any securities of the Company owned or to
                  be owned by such person or to require the Company to include
                  such securities in the securities registered pursuant to the
                  Registration Statement or in any securities being registered
                  pursuant to any other registration statement filed by the
                  Company under the Act;

                           (iv) No consent, approval, authorization or order of,
                  or filing with, any governmental agency or body or any court
                  is required to be obtained or made by the Company for the
                  consummation of the transactions contemplated by this
                  Agreement or the Custody Agreement in connection with the sale
                  of the Offered Securities, except such as have been obtained
                  and made under the Act and such as may be required under state
                  securities laws or under the rules of the NASD;

                           (v) The execution, delivery and performance of this
                  Agreement or the Custody Agreement and the consummation of the
                  transactions herein or therein contemplated will not result in
                  a breach or violation of any of the terms and provisions of,
                  or constitute a default under, any statute, any rule or
                  regulation known to such counsel or order of any governmental
                  agency or body naming the Company or any Selling Stockholder
                  or any court having jurisdiction over the Company or any
                  subsidiary of the Company or any of their properties, or any
                  agreement or instrument to which the Company or any such
                  subsidiary is a party or by which the Company or any such
                  subsidiary is bound or to which any of the properties of the
                  Company or any such subsidiary is subject, or the charter or
                  by-laws of the Company or any such subsidiary;

                           (vi) The Initial Registration Statement was declared
                  effective under the Act as of the date and time specified in
                  such opinion, the Additional Registration Statement (if any)
                  was filed and became effective under the Act as of the date
                  and time (if determinable) specified in such opinion, the
                  Prospectus either was filed with the Commission pursuant to
                  the subparagraph of Rule 424(b) specified in such opinion on
                  the date specified therein or was included in the Initial
                  Registration Statement or the Additional Registration
                  Statement (as the case may be), and, to the best of the
                  knowledge of such counsel, no stop order suspending the
                  effectiveness of a Registration Statement or any part thereof
                  has been issued and no proceedings for that purpose have been
                  instituted or are pending or contemplated under the Act, and
                  each Registration Statement and the Prospectus, and each
                  amendment or supplement thereto, as of their respective
                  effective or issue dates, complied as to form in all material
                  respects with the requirements


                                       11

                  of the Act and the Rules and Regulations; such counsel have no
                  reason to believe that any part of a Registration Statement or
                  any amendment thereto, as of its effective date or as of such
                  Closing Date, contained any untrue statement of a material
                  fact or omitted to state any material fact required to be
                  stated therein or necessary to make the statements therein not
                  misleading; or that the Prospectus or any amendment or
                  supplement thereto, as of its issue date or as of such Closing
                  Date, contained any untrue statement of a material fact or
                  omitted to state any material fact necessary in order to make
                  the statements therein, in the light of the circumstances
                  under which they were made, not misleading; the descriptions
                  in the Registration Statements and Prospectus under the
                  caption "Description of Capital Stock" of statutes, legal and
                  governmental proceedings are accurate in all material respects
                  and fairly present the information required to be shown; and
                  such counsel do not know of any legal or governmental
                  proceedings required to be described in a Registration
                  Statement or the Prospectus which are not described as
                  required or of any contracts or documents of a character
                  required to be described in a Registration Statement or the
                  Prospectus or to be filed as exhibits to a Registration
                  Statement which are not described and filed as required; it
                  being understood that such counsel need express no opinion or
                  belief as to the financial statements and related schedules or
                  other financial data contained in the Registration Statements
                  or the Prospectus;

                           (vii) This Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (viii) Each subsidiary of the Company has been duly

                  under the laws of the jurisdiction of its incorporation, with
                  power and authority to own its properties and conduct its
                  business as described in the Prospectus; and each subsidiary
                  of the Company is duly qualified to do business as a foreign
                  corporation in good standing in all other jurisdictions in
                  which its ownership or lease of property or the conduct of its
                  business requires such qualification; all of the issued and
                  outstanding capital stock of each subsidiary of the Company
                  has been duly authorized and validly issued and is and will be
                  fully paid and nonassessable; and the capital stock of each
                  subsidiary owned by the Company, directly or through
                  subsidiaries, is owned free from liens, encumbrances and
                  defects;

                           (ix) The Offered Securities have been approved for
                  listing subject to notice of issuance on the Nasdaq Stock

                  Prospectus, will not be an "investment company" as defined in
                  the Investment Company Act of 1940; and

                  caption "Certain United States Federal Tax Consequences for
                  Non-United States Holders", insofar as they constitute
                  summaries of the legal matters, documents or proceedings
                  referred to therein, fairly present the information called for
                  with respect to such legal matters, documents and proceedings
                  and fairly summarize the matters referred to therein.

                  (e) The Representatives shall have received an Opinion dated
         such Closing Date, of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo,
         counsel for the Company to the effect that:

                           (i) The Company and its Subsidiaries are not, nor
                  will the conduct of their respective businesses as described
                  in the Prospectus cause any of them to be, subject to the
                  provisions of (x) the Communications Act or to any rules,
                  regulations and policies of the FCC related thereto or (y)
                  state or local telecommunications laws, rules, regulations and
                  policies other than, in the case of certain of the Company's
                  subsidiaries, regulation by the FCC as a "common carrier"
                  under the Act; and

                           (ii) The statements in the Prospectus under the
                  captions "Regulation" and "Risk Factors--Regulatory Risks",

         contemplated in the Power of Attorney executed and delivered by each
         Selling Stockholder and an opinion, dated such Closing Date, of
                     , counsel for the Selling Stockholders, to the effect that:

                           (i) Such Selling Stockholder has valid and
                  unencumbered title to the Offered Securities delivered by such
                  Selling Stockholder on such Closing Date and has full right,
                  power and authority to sell, assign, transfer and deliver the
                  Offered Securities delivered by such Selling Stockholder on
                  such Closing Date hereunder; and the several Underwriters have
                  acquired valid and unencumbered title to the Offered
                  Securities purchased by them from the Selling Stockholders on
                  such Closing Date hereunder;

                           (ii) No consent, approval, authorization or order of,
                  or filing with, any governmental agency or body or any court
                  is required to be obtained or made by any Selling Stockholder
                  for the consummation of the transactions contemplated by [the
                  Custody Agreement or] this Agreement in connection with the
                  sale of the Offered Securities sold by the Selling
                  Stockholders, except such as have been obtained and made under
                  the Act and such as may be required under state securities
                  laws;

                           (iii) The execution, delivery and performance of [the
                  Custody Agreement and] this Agreement and the consummation of
                  the transactions [therein and] herein contemplated will not
                  result in a breach or violation of any of the terms and
                  provisions of, or constitute a default under, any statute, any
                  rule, regulation or order of any governmental agency or body
                  or any court having jurisdiction over any Selling Stockholder
                  or any of their properties or any agreement or instrument to
                  which any Selling Stockholder is a party or by which any
                  Selling Stockholder is bound or to which any of the properties
                  of any Selling Stockholder is subject, or the charter or
                  by-laws of any Selling Stockholder which is a corporation;

                           (iv) The Power of Attorney and related Custody
                  Agreement with respect to each Selling Stockholder has been
                  duly authorized, executed and delivered by such Selling
                  Stockholder and constitute valid and legally binding
                  obligations of each such Selling Stockholder enforceable in
                  accordance with their terms, subject to bankruptcy,
                  insolvency, fraudulent transfer, reorganization, moratorium
                  and similar laws of general applicability relating to or
                  affecting creditors' rights and to general equity principles;
                  and

                           (v) This Agreement has been duly authorized, executed
                  and delivered by each Selling Stockholder.

                  (g) The Representatives shall have received from Cravath,
         Swaine and Moore, counsel for the Underwriters, such opinion or
         opinions, dated such Closing Date, with respect to the incorporation of
         the Company, the validity of the Offered Securities delivered on such
         Closing Date, the Registration Statements, the Prospectus and other
         related matters as the Representatives may require, and the Selling
         Stockholders and the Company shall have furnished to such counsel such
         documents as they reasonably request for the purpose of enabling them
         to pass upon such matters.

                  (h) The Representatives and the Selling Stockholders shall
         have received a certificate, dated such Closing Date, of the President
         or any Vice President and a principal financial or accounting officer
         of the Company in which such officers, to the best of their knowledge
         after reasonable investigation, on behalf of the Company shall state
         that: the representations and warranties of the Company in this
         Agreement are true and correct; the Company has complied with all
         agreements and satisfied all conditions on its part to be performed or
         satisfied hereunder at or prior to such Closing Date; no stop order
         suspending the effectiveness of any Registration Statement has been
         issued and no proceedings for that purpose have been instituted or are
         contemplated by the Commission; the Additional Registration Statement
         (if any) satisfying the requirements of subparagraphs (1) and (3) of
         Rule 462(b) was filed pursuant to Rule 462(b), including payment of the
         applicable filing fee in accordance with Rule 111(a) or (b) under the
         Act, prior to the time the Prospectus was printed and distributed to
         any Underwriter; and, subsequent to the dates of the most recent
         financial statements in the Prospectus, there has been no material
         adverse change, nor any development or event involving a prospective
         material adverse change, in the condition (financial or other),
         business, properties or results of operations of the Company and its
         subsidiaries taken as a whole except as set forth in or contemplated by
         the Prospectus or as described in such certificate.

                  (i) The Representatives shall have received a letter, dated
         such Closing Date, of Arthur Andersen LLP that meets the requirements
         of subsection (a) of this Section, except that the specified date
         referred to in such subsection will be a date not more than three
         business days prior to such Closing Date for the purposes of this
         subsection.

                  (j) The Debt Offering (as defined in the Prospectus) shall
         have been consummated on substantially the same terms as described in
         the Registration Statements, and the Company's Preferred Stock shall
         have been converted into                     shares of the Securities.

The Selling Stockholders and the Company will furnish the Representatives with
such conformed copies of such opinions, certificates, letters and documents as
the Representatives reasonably request. CSFBC may in its sole discretion waive
on behalf of the Underwriters' compliance with any conditions to the obligations
of the Underwriters hereunder, whether in respect of an Optional Closing Date or
otherwise.

         7. Indemnification and Contribution. (a) The Company will indemnify and
hold harmless each Underwriter against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse each Underwriter for any legal or other expenses reasonably
incurred by such Underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action as such expenses are incurred;
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement in or omission or alleged
omission from any of such documents in reliance upon and in conformity with
written information furnished to the Company by any Underwriter through the
Representatives specifically for use therein, it being understood and agreed
that the only such information furnished by any Underwriter consists of the
information described as such in subsection (c) below.

         (b) The Selling Stockholders, severally and not jointly, will indemnify
and hold harmless each Underwriter against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse each Underwriter for any legal or other expenses reasonably
incurred by such Underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action as such expenses are incurred;
provided, however, that the Selling Stockholders will not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement in or omission
or alleged omission from any of such documents in reliance upon and in
conformity with written information furnished to the Company by an Underwriter
through the Representatives specifically for use therein, it being understood
and agreed that the only such information furnished by any Underwriter consists
of the information described as such in subsection (c) below.

         (c) Each Underwriter will severally and not jointly indemnify and hold
harmless the Company and each Selling Stockholder against any losses, claims,
damages or liabilities to which the Company or such Selling Stockholder may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement, the Prospectus, or any amendment or
supplement thereto, or any related preliminary prospectus, or arise out of or
are based upon the omission or the alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in reliance upon and in conformity with written information furnished to
the Company by such Underwriter through the Representatives specifically for use
therein, and will reimburse any legal or other expenses reasonably incurred by
the Company and each Selling Stockholder in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are
incurred, it being understood and agreed that the only such information
furnished by any Underwriter consists of the following information in the
Prospectus furnished on behalf of each Underwriter: the last paragraph at the
bottom of the cover page concerning the terms of the offering by the
Underwriters, the legend concerning


                                       14
<PAGE>


over-allotments, stabilizing and passive market making on the inside front cover
page, the concession and reallowance figures appearing in the fourth paragraph
under the caption "Underwriting" and the information contained in the tenth and
eleventh paragraphs under the caption "Underwriting".

         (d) Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against an indemnifying party under
subsection (a), (b) or (c) above, notify the indemnifying party of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under subsection (a), (b) or (c) above. In case any such action
is brought against any indemnified party and it notifies an indemnifying party
of the commencement thereof, the indemnifying party will be entitled to
participate therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened action in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party unless such settlement includes an
unconditional release of such indemnified party from all liability on any claims
that are the subject matter of such action.

         (e) If the indemnification provided for in this Section is unavailable
or insufficient to hold harmless an indemnified party under subsection (a), (b)
or (c) above, then each indemnifying party shall contribute to the amount paid
or payable by such indemnified party as a result of the losses, claims, damages
or liabilities referred to in subsection (a), (b) or (c) above (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Selling Stockholders on the one hand and the Underwriters on the
other from the offering of the Securities or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company and the Selling Stockholders on
the one hand and the Underwriters on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities as
well as any other relevant equitable considerations. The relative benefits
received by the Company and the Selling Stockholders on the one hand and the
Underwriters on the other shall be deemed to be in the same proportion as the
total net proceeds from the offering (before deducting expenses) received by the
Company and the Selling Stockholders bear to the total underwriting discounts
and commissions received by the Underwriters. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, the Selling
Stockholders or the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission. The amount paid by an indemnified party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this subsection (e) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any action or claim which is the subject of this subsection (e).
Notwithstanding the provisions of this subsection (e), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this subsection
(e) to contribute are several in proportion to their respective underwriting
obligations and not joint.

         (f) The obligations of the Company and the Selling Stockholders under
this Section shall be in addition to any liability which the Company and the
Selling Stockholders may otherwise have and shall extend, upon the same terms
and conditions, to each person, if any, who controls any Underwriter within the
meaning of the Act; and the obligations of the Underwriters under this Section
shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
director of the Company, to each officer of the Company who has signed a
Registration Statement and to each person, if any, who controls the Company
within the meaning of the Act.


                                       15

         8. Default of Underwriters. If any Underwriter or Underwriters default
in their obligations to purchase Offered Securities hereunder on either the
First or any Optional Closing Date and the aggregate number of shares of Offered
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase does not exceed 10% of the total number of shares of Offered Securities
that the Underwriters are obligated to purchase on such Closing Date, CSFBC may
make arrangements satisfactory to the persons from whom such Offered Securities
are to be purchased for the purchase of such Offered Securities by other
persons, including any of the Underwriters, but if no such arrangements are made
by such Closing Date, the non-defaulting Underwriters shall be obligated
severally, in proportion to their respective commitments hereunder, to purchase
the Offered Securities that such defaulting Underwriters agreed but failed to
purchase on such Closing Date. If any Underwriter or Underwriters so default and
the aggregate number of shares of Offered Securities with respect to which such
default or defaults occur exceeds 10% of the total number of shares of Offered
Securities that the Underwriters are obligated to purchase on such Closing Date
and arrangements satisfactory to CSFBC and the persons from whom such Offered
Securities are to be purchased for the purchase of such Offered Securities by
other persons are not made within 36 hours after such default, this Agreement
will terminate without liability on the part of any non-defaulting Underwriter,
the Company or the Selling Stockholders, except as provided in Section 9,
(provided that if such default occurs with respect to Optional Securities after
the First Closing Date, this Agreement will not terminate as to the Firm
Securities or any Optional Securities purchased prior to such termination). As
used in this Agreement, the term "Underwriter" includes any person substituted
for an Underwriter under this Section. Nothing herein will relieve a defaulting
Underwriter from liability for its default.

         9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Selling Stockholders, of the Company or its officers and of the several
Underwriters set forth in or made pursuant to this Agreement will remain in full
force and effect, regardless of any investigation, or statement as to the
results thereof, made by or on behalf of any Underwriter, any Selling
Stockholder, the Company or any of their respective representatives, officers or
directors or any controlling person, and will survive delivery of and payment
for the Offered Securities. If this Agreement is terminated pursuant to Section
8 or if for any reason the purchase of the Offered Securities by the
Underwriters is not consummated, the Company and the Selling Stockholders shall
remain responsible for the expenses to be paid or reimbursed by them pursuant to
Section 5 and the respective obligations of the Company, the Selling
Stockholders, and the Underwriters pursuant to Section 7 shall remain in effect,
and if any Offered Securities have been purchased hereunder the representations
and warranties in Section 2 and all obligations under Section 5 shall also
remain in effect. If the purchase of the Offered Securities by the Underwriters
is not consummated for any reason other than solely because of the termination
of this Agreement pursuant to Section 8 or the occurrence of any event specified
in clause (iii), (iv) or (v) of Section 6(c), the Company and the Selling
Stockholders will, jointly and severally, reimburse the Underwriters for all
out-of-pocket expenses (including fees and disbursements of counsel) reasonably
incurred by them in connection with the offering of the Offered Securities.

         10. Notices. All communications hereunder will be in writing and, if
sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed
to the Representatives, c/o Credit Suisse First Boston Corporation, Eleven
Madison Avenue, New York, N.Y. 10010-3629, Attention: Investment Banking

or if sent to Mode 1 Communications, Inc., will be mailed, delivered or
telegraphed and confirmed to it at                     ; provided, however, that
any notice to an Underwriter pursuant to Section 7 will be mailed, delivered or
telegraphed and confirmed to such Underwriter.

         11. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

         12. Representation. The Representatives will act for the several
Underwriters in connection with the transactions contemplated by this Agreement,
and any action under this Agreement taken by the Representatives jointly or by
CSFBC will be binding upon all the Underwriters.

         13. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.


                                       16

         14. Applicable Law. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York, without regard to
principles of conflicts of laws.

         The Company and each Selling Stockholder hereby submits to the
non-exclusive jurisdiction of the Federal and state courts in the Borough of
Manhattan in The City of New York in any suit or proceeding arising out of or
relating to this Agreement or the transactions contemplated hereby.

understanding of our agreement, kindly sign and return to the Company one of the

with its terms.

Stock shall be reduced to 2,000,000 shares.

respect of each class of capital stock of the Corporation.

A.   COMMON STOCK.

     1. General. The voting, dividend and liquidation rights of the holders of
the Common Stock are subject to and qualified by the rights of the holders of
the Preferred Stock of any series as may be designated by the Board of Directors
upon any issuance of the Preferred Stock of any series.

each share held at all meetings of stockholders. There shall be no cumulative
voting.

     4. Liquidation. Upon the dissolution or liquidation of the Corporation,
whether voluntary or involuntary, holders of Common Stock will be entitled to

stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

B.   PREFERRED STOCK.
     ----------------

     Preferred Stock may be issued from time to time in one or more series, each
of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided. Any shares of
Preferred Stock which may be redeemed, purchased or acquired by the Corporation
may be reissued except as otherwise provided by law. Different series of
Preferred Stock shall not be construed to constitute different classes of shares
for the purposes of voting by classes unless expressly provided.

     Authority is hereby expressly granted to the Board of Directors from time
to time to issue the Preferred Stock in one or more series, and in connection
with the creation of any such series, by resolution or resolutions providing for
the issue of the shares thereof, to determine and fix such voting powers, full
or limited, or no voting powers, and such designations, preferences and relative
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof, including without limitation thereof, dividend rights,
conversion rights, redemption privileges and liquidation preferences, as shall
be stated and expressed in such resolutions, all to the full extent now or
hereafter permitted by the General Corporation Law of Delaware. Without limiting
the generality of the foregoing, the resolutions providing for issuance of any
series of Preferred Stock may provide that such series shall be superior or rank
equally or be junior to the Preferred Stock of any other series to the extent
permitted by law. Except as otherwise provided in this Amended and Restated
Certificate of Incorporation, no vote of the holders of the Preferred Stock or
Common Stock shall be a prerequisite to the designation or issuance of any
shares of any series of the Preferred Stock authorized by and complying with the
conditions of this Amended and Restated Certificate of Incorporation, the right
to have such vote being expressly waived by all present and future holders of
the capital stock of the Corporation.

     FIFTH. The Corporation shall have a perpetual existence.

     SIXTH. In furtherance of and not in limitation of powers conferred by
statute, it is further provided:



                                       3
<PAGE>

     1. Election of directors need not be by written ballot.

     2. The Board of Directors is expressly authorized to adopt, amend or repeal
the By-Laws of the Corporation.


     SEVENTH. Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability. No amendment to or repeal of this provision shall apply to or have
any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

     EIGHTH. The Corporation shall, to the fullest extent permitted by Section
145 of the General Corporation Law of Delaware, as amended from time to time,
indemnify each person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
or she is or was, or has agreed to become, a director or officer of the
Corporation, or is or was serving, or has agreed to serve, at the request of the
Corporation, as a director, officer or trustee of, or in a similar capacity
with, another corporation, partnership, joint venture, trust or other enterprise
(including any employee benefit plan) (all such persons being referred to
hereafter as an "Indemnitee"), or by reason of any action alleged to have been
taken or omitted in such capacity, against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by or on behalf of an Indemnitee in connection with such action, suit
or proceeding and any appeal therefrom.

     As a condition precedent to his or her right to be indemnified, the
Indemnitee must notify the Corporation in writing as soon as practicable of any
action, suit, proceeding or investigation involving him for which indemnity will
or could be sought. With respect to any action, suit, proceeding or
investigation of which the Corporation is so notified, the Corporation will be
entitled to participate therein at its own expense and/or to assume the defense
thereof at its own expense, with legal counsel reasonably acceptable to the
Indemnitee.

     In the event that the Corporation does not assume the defense of any
action, suit, proceeding or investigation of which the Corporation receives
notice under this Article, the Corporation shall pay in advance of the final
disposition of such matter any expenses (including attorneys' fees) incurred by
an Indemnitee in defending a civil or criminal action, suit, proceeding or
investigation or any appeal therefrom; provided, 





                                       4
<PAGE>

however, that the payment of such expenses incurred by an Indemnitee in advance
of the final disposition of such matter shall be made only upon receipt of an
undertaking by or on behalf of the Indemnitee to repay all amounts so advanced
in the event that it shall ultimately be determined that the Indemnitee is not
entitled to be indemnified by the Corporation as authorized in this Article,
which undertaking shall be accepted without reference to the financial ability
of the Indemnitee to make such repayment; and further provided that no such
advancement of expenses shall be made if it is determined that (i) the
Indemnitee did not act in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, or (ii) with
respect to any criminal action or proceeding, the Indemnitee had reasonable
cause to believe his conduct was unlawful.

     The Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by such Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation. In addition, the Corporation shall not indemnify an Indemnitee to
the extent such Indemnitee is reimbursed from the proceeds of insurance, and in
the event the Corporation makes any indemnification payments to an Indemnitee
and such Indemnitee is subsequently reimbursed from the proceeds of insurance,
such Indemnitee shall promptly refund such indemnification payments to the
Corporation to the extent of such insurance reimbursement.

     All determinations hereunder as to the entitlement of an Indemnitee to
indemnification or advancement of expenses shall be made in each instance by (a)
a majority vote of the directors of the Corporation consisting of persons who
are not at that time parties to the action, suit or proceeding in question
("disinterested directors"), whether or not a quorum, (b) a majority vote of a
quorum of the outstanding shares of stock of all classes entitled to vote for
directors, voting as a single class, which quorum shall consist of stockholders
who are not at that time parties to the action, suit or proceeding in question,
(c) independent legal counsel (who may, to the extent permitted by law, be
regular legal counsel to the Corporation), or (d) a court of competent
jurisdiction.

     The indemnification rights provided in this Article (i) shall not be deemed
exclusive of any other rights to which an Indemnitee may be entitled under any
law, agreement or vote of stockholders or disinterested directors or otherwise,
and (ii) shall inure to the benefit of the heirs, executors and administrators
of the Indemnitees. The Corporation may, to the extent authorized from time to
time by its Board of Directors, grant indemnification rights to other employees
or agents of the Corporation or other persons serving the Corporation and such
rights may be equivalent to, or greater or less than, those set forth in this
Article.



                                       5

     NINTH. The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Amended and Restated Certificate of

death, resignation or removal.

     4. Quorum; Action at Meeting. A majority of the total number of the whole
Board of Directors shall constitute a quorum at all meetings of the Board of
Directors. In the event one or more of the directors shall be disqualified to
vote at any meeting, then the required quorum shall be reduced by one for each
such director so disqualified; provided, however, that in no case shall less
than one-third of the number fixed pursuant to Section 1 above constitute a
quorum. In the absence of a quorum at any such meeting, a majority of the
directors present may adjourn the meeting from time to time without further
notice other than announcement at the meeting, until a quorum shall be present.
At any meeting of the Board of Directors at which a quorum is present, the vote
of a majority of those present shall be sufficient to take any action, unless a
different vote is specified by law, by the ByLaws of the Corporation or by this
Amended and Restated Certificate of Incorporation.

     5. Removal. Directors of the Corporation may be removed only for cause by
the affirmative vote of the holders of at least seventy-five percent (75%) of

<PAGE>

vote of a majority of the directors then in office, although less than a quorum,
or by a sole remaining director. A director elected to fill a vacancy shall be
elected to hold office until the next election of directors, subject to the
election and qualification of his or her successor and to his or her earlier
death, resignation or removal.

     7. Stockholder Nominations and Introduction of Business, Etc. Advance
notice of stockholder nominations for election of directors and other business
to be brought by stockholders before a meeting of stockholders shall be given in

written consent in lieu of a meeting. Notwithstanding any other provisions of

Corporation, and notwithstanding the fact that a lesser percentage may be
specified by law, the affirmative vote of the holders of at least seventy-five

     TWELFTH. Special meetings of stockholders may be called at any time only by
the Chairman of the Board of Directors, the President or the Board of Directors.
Business transacted at any special meeting of stockholders shall be limited to
matters relating to the purpose or purposes stated in the notice of meeting.
Notwithstanding any other provision of law, this Amended and Restated
Certificate of Incorporation or the By-Laws of the Corporation, and
notwithstanding the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of at least seventy-five percent (75%) of the
shares of capital stock of the Corporation issued and outstanding and entitled

matter to the stockholders of the Corporation, the Board of Directors may take
into account the interests of creditors, customers, employees and other
constituencies of the Corporation and its subsidiaries and the effect thereof
upon communities in which the Corporation and its subsidiaries do business.
Notwithstanding any other provision of law, this Amended and Restated
Certificate of Incorporation or the By-Laws of the Corporation, and
notwithstanding the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of at least seventy-five percent (75%) of the
shares of capital stock of the Corporation issued and outstanding and entitled
to vote shall be required to amend or repeal, or to adopt any provision
inconsistent with, this Article THIRTEENTH.

oppose any such transaction which the Board of Directors or such committee

Corporation, including, without limitation, the adoption of such plans or the
issuance of such rights, options, capital stock, notes, debentures or other
evidence of indebtedness or other securities of the Corporation, which rights,

provisions and rights applicable to all other holders thereof. Notwithstanding
any other provision of law, this Amended and Restated Certificate of
Incorporation or the By-Laws of the Corporation, and notwithstanding the fact
that a lesser percentage may be specified by law, the affirmative vote of the
holders of at least seventy-five percent (75%) of the shares of capital stock of
the Corporation issued and outstanding and entitled to vote shall be required to
amend or repeal, or to adopt any provision inconsistent with, this Article
FOURTEENTH.

1.10. Such nominations, other than those made by or on behalf of the Board of
Directors, shall be made by notice in writing delivered or mailed by first class
United States mail, postage prepaid, to the Secretary, and received not less
than 60 days nor more than 90 days prior to such meeting; provided, however,
that if less than 70 days' notice or prior public disclosure of the date of the
meeting is given to stockholders, such nomination shall have been mailed or
delivered to the Secretary not later than the close of business on the 10th day
following the date on which the notice of the meeting was mailed or such public
disclosure was made, whichever occurs first. Such notice shall set forth (a) as
to each proposed nominee (i) the name, age, business address and, if known,
residence address of each such nominee, (ii) the principal occupation or
employment of each such nominee, (iii) the number of shares of stock of the

a nominee and to serve as a director if elected); and (b) as to the stockholder
giving the notice (i) the name and address, as they appear on the corporation's
books, of such stockholder and (ii) the class and number of shares of the
corporation which are beneficially owned by such stockholder. The corporation
may require any proposed nominee to furnish such other information as may
reasonably be required by the corporation to determine the eligibility of such
proposed nominee to serve as a director of the corporation.

     The chairman of the meeting may, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.

stockholders, only such business shall be conducted as shall have been properly

given by or at the direction of the Board of Directors, (b) otherwise properly
brought before the meeting by or at the direction of the Board of Directors, or
(c) otherwise properly brought before an annual meeting by a stockholder. For
business to be properly brought before an annual meeting by a stockholder, if
such business relates to the election of directors of the corporation, the
procedures in Section 1.10 must be complied with. If such business relates to
any other matter, the stockholder must have given timely notice thereof in
writing to the Secretary. To be timely, a stockholder's notice must be delivered
to or mailed and received at the principal executive offices of the corporation
not less than 60 days nor more than 90 days prior to the meeting; provided,
however, that in the event that less than 70 days' notice or prior public

by the stockholder to be timely must be so received not later than the close of
business on the 10th day following the date on which such notice of the date of
the meeting was mailed or such public disclosure was made, whichever occurs
first. A stockholder's notice to the Secretary shall set forth as to each matter
the stockholder proposes to bring before the annual meeting (a) a brief
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (b) the name and
address, as they appear on the corporation's books, of the stockholder proposing
such business, (c) the class and number of shares of the corporation which are
beneficially owned by the stockholder, and (d) any material interest of the
stockholder in such business. Notwithstanding anything in these By-Laws to the
contrary, no business shall be conducted at any annual meeting except in
accordance with the procedures set forth in this Section 1.11 and except that
any stockholder proposal which complies with Rule 14a-8 of the proxy rules (or
any successor provision) promulgated under the Securities Exchange Act of 1934,
as amended, and is to be included in the corporation's proxy statement for an
annual meeting of stockholders shall be deemed to comply with the requirements
of this Section 1.11.

     The chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that business was not properly brought before the meeting
in accordance with the provisions of this Section 1.11, and if he should so
determine, the chairman shall so declare to the meeting that any such business
not properly brought before the meeting shall not be transacted.

Chairman of the Board designated by the Chairman of the Board, or the President,
in the order named, shall call meetings of the stockholders to order, and shall
act as chairman of such meeting; provided, however, that the Board of Directors
may appoint any stockholder to act as chairman of any meeting in the absence of
the Chairman of the Board. The Secretary of the corporation shall act as
secretary at all meetings of the

the directors then in office, but only to eliminate vacancies existing by reason
of the death, resignation, removal or expiration of the term of one or more
directors. The directors shall be elected at the annual meeting of stockholders
by such stockholders as have the right to vote on such election. Directors need
not be stockholders of the corporation.

including a vacancy resulting from an enlargement of the Board, shall be filled
only by vote of a majority of the directors then in office, although less than a
quorum, or by a sole remaining director. A director elected to fill a vacancy
shall be elected for the unexpired term of his predecessor in office, and a
director chosen to fill a position resulting from an increase in the number of
directors shall hold office until the next election of directors, subject to the
election and qualification of his successor and to his earlier death,
resignation or removal.

held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, two or more directors, or by
one director in the event that there is only a single director in office.

     2.8 Notice of Special Meetings. Notice of any special meeting of directors

delivering written notice by hand, to his last known business or home address at

need not specify the purposes of the meeting.

     2.9 Meetings by Telephone Conference Calls. Directors or any members of any
committee designated by the directors may participate in a meeting of the Board
of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

     2.10 Quorum. A majority of the total number of the whole Board of Directors
shall constitute a quorum at all meetings of the Board of Directors. In the
event one or more of the directors shall be disqualified to vote at any meeting,
then the required quorum shall be reduced by one for each such director so
disqualified; provided, however, that in no case shall less than one-third (1/3)
of the number fixed pursuant to Section 2.2 above constitute a quorum. In the

adjourn the meeting from time to time without further notice other than
announcement at the meeting, until a quorum shall be present.

the shares of the capital stock of the corporation issued and outstanding and

     2.14 Committees. The Board of Directors may designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The Board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee. In the absence or disqualification of a member of a
committee, the member or members of the committee present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the Board of Directors
and subject to the provisions of the General Corporation Law of the State of
Delaware, shall have and may exercise all the powers and authority of the Board
of Directors in the management of the business and affairs of the corporation
and may authorize the seal of the corporation to be affixed to all papers which
may require it. Each such committee shall keep minutes and make such reports as
the Board of Directors may from time to time request. Except as the Board of
Directors may otherwise determine, any committee may make rules for the conduct
of its business, but unless otherwise provided by the directors or in such
rules, its business shall be conducted as nearly as possible in the same manner
as is provided in these By-laws for the Board of Directors.

     2.15 Compensation of Directors. Directors may be paid such compensation for
their services and such reimbursement for expenses of attendance at meetings as
the Board of Directors may from time to time determine. No such payment shall

subsidiary corporations in any other capacity and receiving compensation for
such service.

of such notice either in writing signed by the person entitled to such notice or
such person's duly authorized attorney, or by telegraph, cable or any other

     5.7 Transactions with Interested Parties. No contract or transaction
between the corporation and one or more of the directors or officers, or between
the corporation and any other corporation, partnership, association, or other
organization in which one or more of the directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or a committee of the
Board of Directors which authorizes the contract or transaction or solely
because his or their votes are counted for such purpose, if:

          (1) The material facts as to his relationship or interest and as to
     the contract or transaction are disclosed or are known to the Board of
     Directors or the committee, and the Board or committee in good faith
     authorizes the contract or transaction by the affirmative votes of a
     majority of the disinterested directors, even though the disinterested
     directors be less than a quorum;

          (2) The material facts as to his relationship or interest and as to
     the contract or transaction are disclosed or are known to the stockholders
     entitled to vote thereon, and the contract or transaction is specifically
     approved in good faith by vote of the stockholders; or

          (3) The contract or transaction is fair as to the corporation as of
     the time it is authorized, approved or ratified, by the Board of Directors,
     a committee of the Board of Directors, or the stockholders.

     Common or interested directors may be counted in determining the presence
of a quorum at a meeting of the Board of Directors or of a committee which
authorizes the contract or transaction.

     5.8 Severability. Any determination that any provision of these By-Laws is
for any reason inapplicable, illegal or ineffective shall not affect or
invalidate any other provision of these By-Laws.

to the masculine, feminine or neuter, singular or plural, as the identity of the
person or persons may require.

         discharged any Indebtedness that was outstanding as of the end of such
         fiscal quarter or if any Indebtedness that was outstanding as of the
         end of such fiscal quarter is to be repaid, repurchased, defeased or

         need to calculate the Consolidated Leverage Ratio (other than, in each
         case, Indebtedness Incurred under any revolving credit agreement), the
         aggregate amount of Indebtedness shall be calculated on a pro forma

         actually earned during the Reference Period in respect of cash or
         Temporary Cash Investments used to repay, repurchase, defease or
         otherwise discharge such Indebtedness;

                  (3) if since the beginning of the Reference Period the Company
         or any Restricted Subsidiary shall have made any Asset Disposition, the
         EBITDA for the Reference Period shall be reduced by an amount equal to

         the subject of such Asset Disposition for the Reference Period or
         increased by an amount equal to the EBITDA (if negative) directly
         attributable thereto for the Reference Period;

                  (4) if since the beginning of the Reference Period the Company
         or any Restricted Subsidiary (by merger or otherwise) shall have made
         an Investment in any Restricted Subsidiary (or any Person which becomes
         a Restricted Subsidiary) or an acquisition of assets which constitutes
         all or substantially all of an operating unit of a business, EBITDA for
         the Reference Period shall be calculated after giving pro forma effect
         thereto (including the Incurrence of any Indebtedness) as if such
         Investment or acquisition occurred on the first day of the Reference
         Period; and

                  (5) if since the beginning of the Reference Period any Person
         (that subsequently became a Restricted Subsidiary or was merged with or
         into the Company or any Restricted Subsidiary since the beginning of
         such Reference Period) shall have made any Asset Disposition, any
         Investment or acquisition of assets that would have required an
         adjustment pursuant to clause (3) or (4) above if made by the Company
         or a Restricted Subsidiary during the Reference Period, EBITDA for the
         Reference Period shall be calculated after giving pro forma effect
         thereto as if such Asset Disposition, Investment or acquisition
         occurred on the first day of the Reference Period.

         such Person is not a Restricted Subsidiary, except that subject to the
         exclusion contained in clause (iv) below, the Company's equity in the
         net income of any such Person for such period shall be included in such
         Consolidated Net Income up to the aggregate amount of cash actually
         distributed by such Person during such period to the Company or a
         Restricted Subsidiary as a dividend or other distribution (subject, in

         below, the Company's equity in the net income of any such Restricted
         Subsidiary for such period shall be included in such Consolidated Net
         Income up to the aggregate amount of cash actually distributed by such
         Restricted Subsidiary during such period to the Company or another
         Restricted Subsidiary as a dividend or other distribution (subject, in
         the case of a dividend or other distribution paid to another Restricted
         Subsidiary, to the limitation contained in this clause applicable to
         such other Restricted Subsidiary) and (B) the Company's equity in a net
         loss of any such Restricted Subsidiary for such period shall be
         included in determining such Consolidated Net Income;

                  (iv) any gain (but not loss) realized upon the sale or other
         disposition of any assets of the Company or its consolidated
         Subsidiaries (including pursuant to any sale-and-leaseback arrangement)

                                                                              26


its authentication. The terms of the Securities set forth in Exhibit A are part
of the terms of this Indenture.

                  SECTION 2.02. Execution and Authentication. Two Officers shall
sign the Securities for the Company by manual or facsimile signature. The
Company's seal shall be impressed, affixed, imprinted or reproduced on the 
Securities and may be in facsimile form.

                  If an Officer whose signature is on a Security no longer holds
that office at the time the Trustee authenticates the Security, the Security
shall be valid nevertheless.

                  A Security shall not be valid until an authorized signatory of
the Trustee manually signs the certificate of authentication on the Security.
The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

                  The Trustee shall authenticate and deliver Securities for
original issue in an aggregate principal amount of $165,000,000, upon a written
order of the Company signed by two Officers or by an Officer and either an
Assistant Treasurer or an Assistant Secretary of the Company. Such order shall
specify the amount of the Securities to be authenticated and the date on which
the original issue of Securities is to be authenticated. The aggregate principal
amount of Securities outstanding at any time may not exceed that amount except
as provided in Section 2.07.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

                  SECTION 2.03. Registrar and Paying Agent. The Company shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar

Company may have one or more co-registrars and one or more additional


<PAGE>


                                                                              27


paying agents. The term "Paying Agent" includes any additional paying agent.

                  The Company shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or co-registrar not a party to this Indenture,
which shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall
notify the Trustee of the name and address of any such agent. If the Company
fails to maintain a Registrar or Paying Agent, the Trustee shall act as such
and shall be entitled to appropriate compensation therefor pursuant to Section
7.07. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar, co-registrar or transfer agent.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent in connection with the Securities.

                  SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to
each due date of the principal and interest on any Security, the Company shall
deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Securityholders or the Trustee all money held by the
Paying Agent for the payment of principal of or interest on the Securities and
shall notify the Trustee of any default by the Company in making any such
payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate
the money held by it as Paying Agent and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money held by it to
the Trustee and to account for any funds disbursed by the Paying Agent. Upon
complying with this Section, the Paying Agent shall have no further liability
for the money delivered to the Trustee.

                  SECTION 2.05. Securityholder Lists. The Trustee shall preserve
in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Securityholders. If the Trustee is
not the Registrar, the Company shall furnish to the Trustee, in writing at least
five Business Days before each interest payment date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of
Securityholders.

                  SECTION 2.06. Transfer and Exchange. The Securities shall be
issued in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer. When a Security is presented to the
Registrar or a co-registrar with a request to register a transfer, the Registrar
shall register the transfer as requested if the requirements of Section 8-401(1)
of the Uniform Commercial Code are met. When Securities are presented to the
Registrar or a co-registrar with a request to exchange them for an equal
principal amount of Securities of other denominations, the Registrar shall make
the exchange as requested if the same requirements are met. To permit
registration of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Securities at the Registrar's or co-registrar's
request. The Company may require payment of a sum sufficient to pay all taxes,
assessments or other governmental charges in connection with any transfer or
exchange pursuant to this Section. The Company shall not be required to make and
the Registrar need not register transfers or exchanges of Securities selected
for redemption (except, in the case of Securities to be redeemed in part, the
portion thereof not to be redeemed) or any Securities for a period of 15 days
before a selection of Securities to be redeemed or 15 days before an interest
payment date.

                  Prior to the due presentation for registration of transfer of
any Security, the Company, the Trustee, the Paying Agent, the Registrar or any
co-registrar may deem and treat the person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving
payment of principal of and interest on such Security and for all other purposes
whatsoever, whether or not such Security is overdue, and none of the Company,
the Trustee, the Paying Agent, the Registrar or any co-registrar shall be
affected by notice to the contrary.

                  All Securities issued upon any transfer or exchange pursuant
to the terms of this Indenture will evidence the same debt and will be entitled
to the same benefits under this Indenture as the Securities surrendered upon
such transfer or exchange.

                  SECTION 2.07. Replacement Securities. If a mutilated Security
is surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or


<PAGE>


                                                                              29


the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

                  Every replacement Security is an additional obligation of the
Company.

                  SECTION 2.08. Outstanding Securities. Securities outstanding
at any time are all Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation and those described in
this Section as not outstanding. A Security does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Security.

                  If a Security is replaced pursuant to Section 2.07, it ceases
to be outstanding unless the Trustee and the Company receive proof satisfactory
to them that the replaced Security is held by a bona fide purchaser.

                  If the Paying Agent segregates and holds in trust, in
accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, and the Paying Agent is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture, then on
and after that date such Securities (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

                  SECTION 2.09. Temporary Securities. Until definitive
Securities are ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Securities
and deliver them in exchange for temporary Securities.

                  SECTION 2.10 Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one

                                                                              30


else shall cancel and destroy (subject to the record retention requirements of
the Exchange Act) all Securities surrendered for registration of transfer,
exchange, payment or cancellation and deliver a certificate of such destruction
to the Company unless the Company directs the Trustee to deliver canceled
Securities to the Company. The Company may not issue new Securities to replace
Securities it has redeemed, paid or delivered to the Trustee for cancellation.

                  SECTION 2.11. Defaulted Interest. If the Company defaults in a
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

                  SECTION 2.12. CUSIP Numbers. The Company in issuing the
Securities may use "CUSIP" numbers (if then generally in use) and, if so, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.

                  SECTION 3.01. Notices to Trustee. If the Company elects to
redeem Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

                  The Company shall give each notice to the Trustee provided for

consents to a shorter period. Such notice shall be accompanied by an Officers'

                                                                              31


Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein.

                  SECTION 3.02. Selection of Securities To Be Redeemed. If fewer
than all the Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed pro rata or by lot or by a method that complies with
applicable legal and securities exchange requirements, if any, and that the
Trustee in its sole discretion shall deem to be fair and appropriate and in
accordance with methods generally used at the time of selection by fiduciaries
in similar circumstances. The Trustee shall make the selection from outstanding
Securities not previously called for redemption. The Trustee may select for
redemption portions of the principal of Securities that have denominations
larger than $1,000. Securities and portions of them the Trustee selects shall be
in amounts of $1,000 or a whole multiple of $1,000. Provisions of this Indenture
that apply to Securities called for redemption also apply to portions of
Securities called for redemption. The Trustee shall notify the Company promptly
of the Securities or portions of Securities to be redeemed.

                  SECTION 3.03. Notice of Redemption. At least 30 days but not
more than 60 days before a date for redemption of Securities, the Company shall
mail a notice of redemption by first-class mail to each Holder of Securities to
be redeemed at such Holder's registered address.

                  The notice shall identify the Securities to be redeemed and
shall state:

                  (1) the redemption date;

                  (2) the redemption price;

                  (3) the name and address of the Paying Agent;

                  (4) that Securities called for redemption must be surrendered
         to the Paying Agent to collect the redemption price;

                  (5) if fewer than all the outstanding Securities are to be 
         redeemed, the identification and principal amounts of the particular 
         Securities to be redeemed;

                  (6) that, unless the Company defaults in making such
         redemption payment or the Paying Agent is prohibited from making such
         payment pursuant to the terms of this Indenture, interest on Securities
         (or portion

                                                                              32


         thereof) called for redemption ceases to accrue on and after the
         redemption date;

                  (7) the paragraph of the Securities pursuant to which the
         Securities called for redemption are being redeemed; and

                  (8) that no representation is made as to the correctness or
         accuracy of the CUSIP number, if any, listed in such notice or printed
         on the Securities.

                  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section.

                  SECTION 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date). Failure to give
notice or any defect in the notice to any Holder shall not affect the validity
of the notice to any other Holder.

                  SECTION 3.05. Deposit of Redemption Price. By 11:00 p.m.
eastern standard time on the redemption date, the Company shall deposit with the
Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the redemption price of and
accrued interest on all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which have been
delivered by the Company to the Trustee for cancellation.

                  SECTION 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security
surrendered.

                  SECTION 4.01. Payment of Securities. The Company shall
promptly pay the principal of and interest on the Securities on the dates and in
the manner provided in the Securities and in this Indenture. Principal and
interest shall be considered paid on the date due if on such date the Trustee or
the Paying Agent holds in accordance with this Indenture money sufficient to pay
all principal and interest then due and the Trustee or the Paying Agent, as the
case may be, is not prohibited from paying such money to the Securityholders on
that date pursuant to the terms of this Indenture.

                  The Company shall pay interest on overdue principal at the
rate specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  SECTION 4.02. 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
Securityholders 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 reports to be so filed and provided at the times specified for the
filing of such information, documents and reports under such Sections. The
Company also shall comply with the other provisions of TIA ss. 314(a) and, so
long as the Pledge Agreement is in effect, TIA ss. 314(b).

                  SECTION 4.03. 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 if such Indebtedness
is Incurred prior to December 31, 2000 or 5.0 to 1 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 $50,000,000 less the sum of all principal payments with
         respect to such Indebtedness pursuant to Section 4.06(a)(ii)(A);

                  (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
         who 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 Securities;

                  (3) the Securities;

                  (4) Indebtedness outstanding on the Issue Date (other than

         Incurred pursuant to Section 4.03(a) or pursuant to clause (3) or (4)
         of this Section 4.03(b) or 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 Incurred pursuant to clause (10), such
         Refinancing Indebtedness shall be Incurred only by such Restricted
         Subsidiary;

                  (6) Hedging Obligations consisting of Interest Rate Agreements
         directly related to Indebtedness permitted to be Incurred by the
         Company or any Restricted Subsidiary pursuant to this Indenture;

                  (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,

         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;

                  (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 Section 4.05(a)(3)(B) or Section 4.05(b)(i) to make a
         Restricted Payment; provided, however, that such Indebtedness does not
         mature prior to the Stated Maturity of the Securities and has an
         Average Life longer than the Average Life of the Securities;

                  (9) Guarantees by any Restricted Subsidiary of the Securities,
         Indebtedness Incurred pursuant to paragraph (a) above and any
         Indebtedness that Refinances the Securities 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 Restricted 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 Indebtedness
         pursuant to Section 4.03(a);

                  (11) Indebtedness in an aggregate principal amount which,
         together with all other Indebtedness of the Company and its Restricted
         Subsidiaries outstanding on the date of such Incurrence (other than
         Indebtedness permitted by clauses (1) through (10) of this Section

                  (c) Notwithstanding the foregoing, the Company shall not Incur
any Indebtedness pursuant to Section 4.03(b) if the proceeds thereof are used,
directly or indirectly, to Refinance any Subordinated Obligations unless such
Indebtedness shall be subordinated to the Securities to at least the same extent
as such Subordinated Obligations.

                  (d) For purposes of determining compliance with this Section
4.03, (i) in the event that an item of Indebtedness meets the criteria of more
than one of the types of Indebtedness described herein, 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 herein. 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.

                  SECTION 4.04. Limitation on Restricted Payments. (a) The

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 under Section 4.03(a); 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 (treated as one 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

                  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

                  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 Section 4.05(a) shall not
prohibit:

         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 
         Section 4.04(a);

                  (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 Section 4.03; provided, however, that such purchase,
         repurchase, redemption, defeasance 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 Section 4.04(a); 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

         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.

                  SECTION 4.05. Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any

         Restricted Subsidiary pursuant to an agreement relating to any
         Indebtedness Incurred by such Restricted Subsidiary on or prior to the

         (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

         referred to in clause (i) or (ii) of this Section 4.05 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 favor able to the Securityholders
         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 Section
         4.03(b)(1); provided, however, that such encumbrances and restrictions

         any) and principal (whether at stated maturity, by way of a sinking
         fund applicable thereto, by way of any mandatory redemption,

         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 distributions
         listed in clauses (a), (b) and (c) above 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 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

                  (vi) in the case of clause (c) above, restrictions contained
         in security agreements or mortgages securing Indebtedness of a

         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.

                  SECTION 4.06. 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

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) 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 Securities to purchase Securities pursuant to and
subject to the conditions of Section 4.06(b); 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
Section 4.06, the Company and the Restricted Subsidiaries shall not be required
to apply any Net Avail able Cash in accordance with this Section 4.06(a) except
to the extent that the aggregate Net Available Cash from all Asset Dispositions
which are not applied in accordance with this Section 4.06(a) exceeds
$5,000,000. Pending application of Net Available Cash pursuant to this Section
4.06(a), such Net Available Cash shall be invested in Permitted Investments or
used to reduce outstanding borrowings under revolving credit facilities.

                  For the purposes of Section 4.06(a)(i), 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

                  (b) In the event of an Asset Disposition that requires the
purchase of Securities pursuant to Section 4.06(a)(ii)(C), the Company shall be
required to purchase Securities tendered pursuant to an offer by the Company
for the Securities (the "Offer") at a purchase price of 100% of their principal
value (without premium) plus accrued but unpaid interest in accordance with the
procedures (including prorating in the event of oversubscription) set forth in
Section 4.06(c). The Company shall not be required to make an Offer to purchase
Securities pursuant to this Section 4.06 if the Net Available Cash available
therefor is less than $5,000,000 (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) (1) Promptly, and in any event within 10 days after the
         Company becomes obligated to make an Offer, the Company shall be
         obligated to deliver to the Trustee and send, by first-class mail to
         each Holder, a written notice stating that the Holder may elect to have
         his Securities purchased by the Company either in whole or in part
         (subject to prorating as hereinafter described in the event the Offer
         is oversubscribed) in integral multiples of $1,000 of principal amount,
         at the applicable purchase price. The notice shall specify a purchase
         date not less than 30 days nor more than 60 days after the date of such
         notice (the "Purchase Date") and shall contain such information
         concerning the business of the Company which the Company in good faith
         believes will enable such Holders to make an informed decision (which
         at a minimum will include (i) the most recently filed Annual Report on
         Form 10-K (including audited consolidated financial statements) of the
         Company, the most recent subsequently filed quarterly report on Form
         10-Q and any current report on Form 8-K of the Company filed subsequent
         to such quarterly report, other than current reports describing Asset
         Dispositions otherwise described in the offering materials (or
         corresponding successor reports), (ii) a description of material
         developments in the Company's business subsequent to the date of the
         latest of such reports, and (iii) if material, appropriate pro forma
         financial information) and all instructions and materials necessary to
         tender Securities pursuant to the Offer, together with the information
         contained in clause (3).

                  (2) Not later than the date upon which written notice of an
         Offer is delivered to the Trustee, the


<PAGE>


                                                                              43


         Company shall deliver to the Trustee an Officers' Certificate as to (i)
         the amount of the Offer (the "Offer Amount"), (ii) the allocation of
         the Net Available Cash from the Asset Dispositions pursuant to which
         such Offer is being made and (iii) the compliance of such allocation
         with the provisions of Section 4.06(a). On such date, the Company shall
         also irrevocably deposit with the Trustee or with a paying agent (or,
         if the Company is acting as its own paying agent, segregate and hold in
         trust) in Temporary Cash Investments, maturing on the last day prior to
         the Purchase Date or on the Purchase Date if funds are immediately
         available by open of business, an amount equal to the Offer Amount to
         be held for payment in accordance with the provisions of this Section.
         Upon the expiration of the period for which the Offer remains open (the
         "Offer Period"), the Company shall deliver to the Trustee for
         cancellation the Securities or portions thereof which have been
         properly tendered to and are to be accepted by the Company. The Trustee
         shall, on the Purchase Date, mail or deliver payment to each tendering
         Holder in the amount of the purchase price. In the event that the
         aggregate purchase price of the Securities delivered by the Company to
         the Trustee is less than the Offer Amount, the Trustee shall deliver
         the excess to the Company immediately after the expiration of the Offer
         Period for application in accordance with this Section.

                  (3) Holders electing to have a Security purchased shall be
         required to surrender the Security, with an appropriate form duly
         completed, to the Company at the address specified in the notice at
         least three Business Days prior to the Purchase Date. Holders shall be
         entitled to withdraw their election if the Trustee or the Company
         receives not later than one Business Day prior to the Purchase Date, a
         telex, facsimile transmission or letter setting forth the name of the
         Holder, the principal amount of the Security which was delivered for
         purchase by the Holder and a statement that such Holder is withdrawing
         his election to have such Security purchased. If at the expiration of
         the Offer Period the aggregate principal amount of Securities
         surrendered by holders thereof exceeds the Offer Amount, the Company
         shall select the Securities to be purchased on a pro rata basis (with
         such adjustments as may be deemed appropriate by the Company so that
         only Securities in denominations of $1,000, or integral multiples
         thereof, shall be purchased). Holders whose Securities are purchased
         only in part shall be issued new Securities equal in principal

                                                                              44


         amount to the unpurchased portion of the Securities surrendered.

                  (4) At the time the Company delivers Securities to the Trustee
         which are to be accepted for purchase, the Company shall also deliver
         an Officers' Certificate stating that such Securities are to be
         accepted by the Company pursuant to and in accordance with the terms of
         this Section. A Security shall be deemed to have been accepted for
         purchase at the time the Trustee, directly or through an agent, mails
         or delivers payment therefor to the surrendering Holder.

                  (d) 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 Securities pursuant to
this Section. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this Section by virtue thereof.

                  SECTION 4.07. 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 (i) 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,
(ii) if such Affiliate Transaction involves an amount in excess of $1,000,000,
(1) are set forth in writing and (2) have been approved by a majority of the
members of the Board of Directors having no personal stake in such Affiliate
Transaction and (iii) if such Affiliate Transaction involves an amount in excess
of $5,000,000, have been determined by a nationally recognized investment
banking firm to be fair, from a financial standpoint, to the Company and its
Restricted Subsidiaries.

                  (b) The provisions of Section 4.07(a) shall not prohibit (i)
any Restricted Payment permitted to be paid pursuant to Section 4.04, (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 $1,000,000 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.

                  SECTION 4.08. 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 in Section 4.04 if
made on the date of such issuance, sale or other disposition.

                  SECTION 4.09. Change of Control. (a) Upon the occurrence of a
Change of Control, each Holder shall have the right to require that the Company
repurchase such Holder's Securities at a purchase price in cash equal to 101% of
the principal 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

                  (b) Within 30 days following any Change of Control, the
Company shall mail a notice to each Holder with a copy to the Trustee (the

         has the right to require the Company to purchase such Holder's
         Securities at a purchase price in cash equal to 101% of the principal
         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

delivered for purchase by the Holder and a statement that such Holder is
withdrawing his election to have such Security purchased.

                  (d) On the purchase date, all Securities purchased by the
Company under this Section shall be delivered by the Trustee for cancellation,
and the Company shall pay the purchase price plus accrued and unpaid interest,
if any, to the Holders entitled thereto.

the Company would be obligated to pay for such Securities tendered pursuant to a
Change of Control Offer, such Holder will be entitled to receive only the
redemption price. Notwithstanding the foregoing provisions of this Section, the
Company will not be required to make a Change of Control Offer upon 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 this
Section 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.

                  (f) The Company shall comply, to the extent applicable, with

Date or thereafter acquired, other than Permitted Liens, without effectively
providing that the Securities shall be secured equally and ratably with (or
prior to) the obligations so secured for so long as such obligations are so
secured.

                  SECTION 4.11. 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

                  SECTION 4.14. Further Instruments and Acts. Upon request of

obligations with respect to the Pledged Securities shall be as set forth in the
Pledge Agreement.

         million, or its foreign currency equivalent at the time;

                  (8) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (B) appoints a Custodian of the Company or

         invalid or unenforceable or the Company shall assert, if any pleading
         in any court of competent jurisdiction that such security interest is
         invalid and unenforceable.

                  The foregoing will constitute Events of Default whatever the

or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.


<PAGE>


                                                                              52


                  The term "Bankruptcy Law" means Title 11, United States Code,
or any similar Federal or state law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

                  A Default under clauses (4), (5), or (9) is not an Event of
Default until the Trustee or the holders of at least 25% in principal amount of
the outstanding Securities notify the Company of the Default and the Company
does not cure such Default within the time specified after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default".

                  The Company shall deliver to the Trustee, within 30 days after
the occurrence thereof, written notice in the form of an Officers' Certificate
of any Event of Default under clause (6) and any event which with the giving of
notice or the lapse of time would become an Event of Default under clause (4),
(5) or (9), its status and what action the Company is taking or proposes to take
with respect thereto.

                  SECTION 6.02. Acceleration. If an Event of Default (other than
an Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the Securities by notice to the
Company and the Trustee, may declare the principal value of and accrued but
unpaid interest on all the Securities (collectively, the "Default Amount") to be
due and payable. Upon such a declaration, the Default Amount shall be due and
payable immediately. If an Event of Default specified in Section 6.01(7) or (8)
with respect to the Company occurs, the Default Amount on all the Securities
shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Securityholders. The
Holders of a majority in principal amount of the Securities by notice to the
Trustee may rescind an acceleration and its consequences if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
have been cured or waived except nonpayment of principal or interest that has
become due solely because of acceleration. No such rescission shall affect any
subsequent Default or impair any right consequent thereto.

                  SECTION 6.03. Other Remedies. If an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of or


<PAGE>


                                                                              53


interest on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Securityholder in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

                  SECTION 6.04. Waiver of Past Defaults. The Holders of a
majority in principal amount of the Securities by notice to the Trustee may
waive an existing Default and its consequences except (i) a Default in the
payment of the principal of or interest on a Security (ii) a Default arising
from the failure to redeem or purchase any Security when required pursuant to
this Indenture or (iii) a Default in respect of a provision that under Section
9.02 cannot be amended without the consent of each Securityholder affected. When
a Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or impair any consequent right.

                  SECTION 6.05. Control by Majority. The Holders of a majority
in principal amount of the Securities may 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. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or the
Pledge Agreement or, subject to Section 7.01, that the Trustee determines is
unduly prejudicial to the rights of other Securityholders or would involve the
Trustee in personal liability; provided, however, that the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

                  SECTION 6.06. Limitation on Suits. Except to enforce the right
to receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture, the Pledge
Agreement or the Securities unless:

                  (1) the Holder gives to the Trustee written notice stating
         that an Event of Default is continuing;


<PAGE>


                                                                              54


                  (2) the Holders of at least 25% in principal amount of the
         Securities make a written request to the Trustee to pursue the remedy;

                  (3) such Holder or Holders offer to the Trustee reasonable
         security or indemnity against any loss, liability or expense;

                  (4) the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of security or
         indemnity; and

                  (5) the Holders of a majority in principal amount of the
         Securities do not give the Trustee a direction inconsistent with the
         request during such 60-day period.

                  A Securityholder may not exercise its rights under this
Indenture to prejudice the rights of another Securityholder or to obtain a
preference or priority over another Securityholder.

                  SECTION 6.07. Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of principal of and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Securities, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

                  SECTION 6.08. Collection Suit by Trustee. If an Event of
Default specified in Section 6.01(1) or (2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount then due and owing (together with
interest on any unpaid interest to the extent lawful) and the amounts provided
for in Section 7.07.

                  SECTION 6.09. Trustee May File Proofs of Claim. The Trustee
may file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments

                                                                              55


directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

                  SECTION 6.10.  Priorities.  If the Trustee collects any money
or property pursuant to this Article 6, it shall pay out the money or property
in the following order:

                  FIRST: to the Trustee for amounts due under Section 7.07;

                  SECOND: to Securityholders for amounts due and unpaid on the
         Securities for principal and interest, ratably, without preference or
         priority of any kind, according to the amounts due and payable on the
         Securities for principal and interest, respectively; and

                  THIRD: to the Company.

                  The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section. At least 15 days before
such record date, the Company shall mail to each Securityholder and the Trustee
a notice that states the record date, the payment date and amount to be paid.

                  SECTION 6.11. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant. This Section does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit
by Holders of more than 10% in principal amount of the Securities.

                  SECTION 6.12. Waiver of Stay or Extension Laws. The Company
(to the extent it may lawfully do so) shall not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and shall not hinder, delay or


<PAGE>


                                                                              56


impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law had
been enacted.


                                    ARTICLE 7

                                     Trustee
                                     -------

                  SECTION 7.01. Duties of Trustee. (a) If an Event of Default
has occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

                  (b)  Except during the continuance of an Event of Default:

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture and the
         Pledge Agreement and no implied covenants or obligations shall be read
         into this Indenture and the Pledge Agreement against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture and the Pledge Agreement. However, the Trustee shall
         examine the certificates and opinions to determine whether or not they
         conform to the requirements of this Indenture and the Pledge Agreement.

                  (c) The Trustee may not be relieved from liability for its
own negligent action, its own negligent failure to act or its own wilful
misconduct, except that:

                  (1) this paragraph does not limit the effect of paragraph (b)
         of this Section;

                  (2) the Trustee shall not be liable for any error of judgment
         made in good faith by a Trust Officer unless it is proved that the
         Trustee was negligent in ascertaining the pertinent facts; and

                  (3) the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith

         in accordance with a direction received by it pursuant to Section 6.05.

                  (d) Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b) and (c) of this Section.

                  (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

from other funds except to the extent required by law.

                  (g) No provision of this Indenture or the Pledge Agreement
shall require the Trustee to expend or risk its own funds or otherwise incur
financial liability in the performance of any of its duties hereunder or in the
exercise of any of its rights or powers, if it shall have reasonable grounds to
believe that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

                  (h) Every provision of this Indenture or the Pledge Agreement
relating to the conduct or affecting the liability of or affording protection to
the Trustee shall be subject to the provisions of this Section and to the
provisions of the TIA.

                  SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on 
any document believed by it to be genuine and to have been signed or presented
by the proper per son. The Trustee need not investigate any fact or matter
stated in the document.

                  (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel. The Trustee shall
not be liable for any action it takes or omits to take in good faith in reliance
on the Officers' Certificate or Opinion of Counsel.

                  (c) The Trustee may act through agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; provided, however, that the Trustee's conduct does not
constitute wilful misconduct or negligence.

                  (e) The Trustee may consult with counsel, and the advice or
opinion of counsel with respect to legal matters relating to this Indenture and
the Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it here under
in good faith and in accordance with the advice or opinion of such counsel.

                  (f) Except with respect to Section 4.01, the Trustee shall
have no duty to inquire as to the performance of the Company with respect to the
covenants contained in Article 4. In addition, the Trustee shall not be deemed
to have knowledge of an Event of Default except (i) any Default or Event of
Default occurring pursuant to Sections 4.01, 6.01(1) or 6.01(2) or (ii) any
Default or Event of Default of which the Trustee shall have received written
notification or obtained actual knowledge.

                  (g) Delivery of reports, information and documents to the
Trustee under Section 4.02 is for informational purposes only and the Trustee's
receipt of the foregoing shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of their covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

                  SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

                  SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, the Pledge Agreement or the Securities, it shall not be
accountable for the Company's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Company in the Indenture or in
any document issued in connection with the sale of the Securities or in the
Securities other than the Trustee's certificate of authentication.

                  SECTION 7.05. Notice of Defaults. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 90 days after it occurs. Except in
the case

                                                                              59


of a Default in payment of principal of or interest on any Security (including
payments pursuant to the mandatory redemption provisions of such Security, if
any), the Trustee may withhold the notice if and so long as a committee of its
Trust Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

                  SECTION 7.06. Reports by Trustee to Holders. As promptly as
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 15 in each year, the Trustee
shall mail to each Securityholder a brief report dated as May 15 that complies
with TIA ss. 313(a). The Trustee also shall comply with TIA ss. 313(b).

                  A copy of each report at the time of its mailing to
Securityholders shall be filed with the SEC and each stock exchange (if any) on
which the Securities are listed. The Company agrees to notify promptly the
Trustee whenever the Securities become listed on any stock exchange and of any
delisting thereof.

                  SECTION 7.07. Compensation and Indemnity. The Company shall
pay to the Trustee from time to time reasonable compensation for its services.
The Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Company shall indemnify the Trustee against any and all loss,
liability or expense (including attorneys' fees) incurred by it in connection
with the administration of this trust and the performance of its duties
hereunder. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend the
claim and the Trustee may have separate counsel and the Company shall pay the
fees and expenses of such counsel. The Company need not reimburse any expense or
indemnify against any loss, liability or expense incurred by the Trustee through
the Trustee's own wilful misconduct, negligence or bad faith.

                  To secure the Company's payment obligations in this Section,
the Trustee shall have a lien prior to the Securities on all money or property
held or collected by the


<PAGE>


                                                                              60


Trustee other than money or property held in trust to pay principal of and
interest on particular Securities.

                  The Company's payment obligations pursuant to this Section
shall survive the discharge of this Indenture. When the Trustee incurs expenses
after the occurrence of a Default specified in Section 6.01(7) or (8) with
respect to the Company, the expenses are intended to constitute expenses of
administration under the Bankruptcy Law.

                  SECTION 7.08. Replacement of Trustee. The Trustee may resign
at any time by so notifying the Company. The Holders of a majority in principal
amount of the Securities may remove the Trustee by so notifying the Trustee and
may appoint a successor Trustee. The Company shall remove the Trustee if:

                  (1) the Trustee fails to comply with Section 7.10;

                  (2) the Trustee is adjudged bankrupt or insolvent;

                  (3) a receiver or other public officer takes charge of the
             Trustee or its property; or

                  (4) the Trustee otherwise becomes incapable of acting.

                  If the Trustee resigns, is removed by the Company or by the
Holders of a majority in principal amount of the Securities and such Holders do
not reasonably promptly appoint a successor Trustee, or if a vacancy exists in
the office of Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

                  If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in principal amount of the Securities may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                                                                              61


                  If the Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

                  Notwithstanding the replacement of the Trustee pursuant to
this Section, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

                  SECTION 7.09. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

                  In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

                  SECTION 7.10. Eligibility; Disqualification. The Trustee shall
at all times satisfy the requirements of TIA ss. 310(a). The Trustee shall have
a combined capital and surplus of at least $25,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with
TIA ss. 310(b); provided, however, that there shall be excluded from the
operation of TIA ss. 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are out standing if the requirements for such exclusion set forth in
TIA ss. 310(b)(1) are met.

                  SECTION 7.11. Preferential Collection of Claims Against
Company. The Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated.

                                    ARTICLE 8

                       Discharge of Indenture; Defeasance
                       ----------------------------------

                  SECTION 8.01. Discharge of Liability on Securities;
Defeasance. (a) When (i) the Company delivers to the Trustee all outstanding
Securities (other than Securities replaced pursuant to Section 2.07) for
cancellation or (ii) all outstanding Securities have become due and payable,
whether at maturity or as a result of the mailing of a notice of redemption
pursuant to Article 3 hereof and the Company irrevocably deposits with the
Trustee funds sufficient to pay at maturity or upon redemption all outstanding
Securities, including interest thereon to maturity or such redemption date
(other than Securities replaced pursuant to Section 2.07), and if in either case
the Company pays all other sums payable hereunder by the Company, then this
Indenture shall, subject to Sections 8.01(c), cease to be of further effect. The
Trustee shall acknowledge satisfaction and discharge of this Indenture on demand
of the Company accompanied by an Officers' Certificate and an Opinion of Counsel
and at the cost and expense of the Company.

                  (b) Subject to Sections 8.01(c) and 8.02, the Company at any
time may terminate (i) all its obligations under the Securities and this
Indenture ("legal defeasance option") or (ii) its obligations under Sections
4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13 and 4.14
and the operation of Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) and 6.01(9)
(but, in the case of Sections 6.01(7) and (8), with respect only to Significant
Subsidiaries) and the limitations contained in Sections 5.01(a)(iii) and (iv)
("covenant defeasance option"). 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 Securities may not be accelerated because of an Event of Default with
respect thereto. If the Company exercises its covenant defeasance option,
payment of the Securities may not be accelerated because of an Event of Default
specified in Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) and 6.01(9) (but, in
the case of Sections 6.01(7) and (8), with respect only to Significant
Subsidiaries) or because of the failure of the Company to comply with Section
5.01(a)(iii) or (iv).

                  Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall

                                                                              63


acknowledge in writing the discharge of those obligations that the Company
terminates.

                  (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07 and 8.05 shall survive.

                  SECTION 8.02. Conditions to Defeasance. The Company may
exercise its legal defeasance option or its covenant defeasance option only if:

                  (1) the Company irrevocably deposits in trust with the Trustee
         money or U.S. Government Obligations for the payment of principal of
         and interest on the Securities to maturity or redemption, as the case
         may be;

                  (2) the Company delivers to the Trustee a certificate from a
         nationally recognized firm of independent accountants expressing their
         opinion that the payments of principal and interest when due and
         without reinvestment on the deposited U.S. Government Obligations plus
         any deposited money without investment will provide cash at such times
         and in such amounts as will be sufficient to pay principal and interest
         when due on all the Securities to maturity or redemption, as the case
         may be;

                  (3) 123 days pass after the deposit is made and during the
         123-day period no Default specified in Sections 6.01(7) or (8) with
         respect to the Company occurs which is continuing at the end of the
         period;

                  (4) the deposit does not constitute a default under any other
         agreement binding on the Company;

                  (5) the Company delivers to the Trustee an Opinion of Counsel
         to the effect that the trust resulting from the deposit does not
         constitute, or is qualified as, a regulated investment company under
         the Investment Company Act of 1940;

                  (6) in the case of the legal defeasance option, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (i) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (ii) since the date of this
         Indenture there has been a change in the applicable Federal income tax
         law, in either case to


<PAGE>


                                                                              64

         the effect that, and based thereon such Opinion of Counsel shall
         confirm that, the Securityholders will not recognize income, gain or
         loss for Federal income tax purposes as a result of such defeasance and
         will be subject to Federal income tax on the same amounts, in the same
         manner and at the same times as would have been the case if such
         defeasance had not occurred;

                  (7) in the case of the covenant defeasance option, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Security holders will not recognize income, gain or loss for
         Federal income tax purposes as a result of such covenant defeasance
         and will be subject to Federal income tax on the same amounts, in the
         same manner and at the same times as would have been the case if such
         covenant defeasance had not occurred; and

                  (8) the Company delivers to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance and discharge of the Securities as
         contemplated by this Article 8 have been complied with.

                  Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

                  SECTION 8.03. Application of Trust Money. The Trustee shall
hold in trust money or U.S. Government Obligations deposited with it pursuant
to this Article 8. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.

                  SECTION 8.04. Repayment to Company. The Trustee and the Paying
Agent shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

                  Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal or interest that remains unclaimed for two
years, and, thereafter, Securityholders entitled to the money must look to the
Company for payment as general creditors.

         SECTION 8.05. Indemnity for Government Obligations. The Company shall
pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or


<PAGE>


                                                                              65


assessed against deposited U.S. Government Obligations or the principal and
interest received on such U.S. Government Obligations.

                  SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee
or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8; provided, however, that, if the
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.


                                    ARTICLE 9

                                   Amendments
                                   ----------

         SECTION 9.01. Without Consent of Holders. The Company and the Trustee
may amend this Indenture or the Securities without notice to or consent of any
Security holder:

                  (1) to cure any ambiguity, omission, defect or inconsistency;

                  (2) to comply with Article 5;

                  (3) to provide for uncertificated Securities in addition to or
         in place of certificated Securities; provided, however, that the
         uncertificated Securities are issued in registered form for purposes of
         Section 163(f) of the Code or in a manner such that the uncertificated
         Securities are described in Section 163(f)(2)(B) of the Code;

                  (4) to add guarantees with respect to the Securities or to
         secure the Securities;

                  (5) to add to the covenants of the Company for the benefit of
         the Holders or to surrender any right or power herein conferred upon
         the Company;


<PAGE>


                                                                              66

                  (6) to comply with any requirements of the SEC in connection
         with qualifying, or maintaining the qualification of, this Indenture
         under the TIA;

                  (7) to make any change that does not adversely affect the
         rights of any Securityholder; or

                  (8) make any change in the Pledge Agreement that would
         adversely affect the rights of any Securityholder.

                  After an amendment under this Section becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section.

                  SECTION 9.02. With Consent of Holders. The Company and the
Trustee may amend this Indenture or the Securities without notice to any
Securityholder but with the written consent of the Holders of at least a
majority in principal amount of the Securities then outstanding (including
consents obtained in connection with a tender offer or exchange for the
Securities). However, without the consent of each Securityholder affected
thereby, an amendment may not:

                  (1) reduce the amount of Securities whose Holders must consent
         to an amendment;

                  (2) reduce the rate of or extend the time for payment of
         interest on any Security;

                  (3) reduce the principal of or extend the Stated Maturity of
         any Security;

                  (4) reduce the premium payable upon the redemption of any
         Security or change the time at which any Security may be redeemed in
         accordance with Article 3;

                  (5) make any Security payable in money other than that stated
         in the Security;

                  (6) impair the right of any Securityholder to receive payment
         of principal of and interest on such Holder's Securities on or after
         the due dates therefor or to institute suit for any payment on or with
         respect to such Holder's Securities;


<PAGE>


                                                                              67


                  (7) make any change in Section 6.04 or 6.07 or the second
         sentence of this Section; or

                  (8) make any changes in the Pledge Agreement that would
         adversely affect the rights of any Security holders.

                  It shall not be necessary for the consent of the Holders under
this Section to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

                  After an amendment under this Section becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section.

                  SECTION 9.03. Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities shall comply with the TIA as then
in effect.

                  SECTION 9.04. Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such
Holder's Security or portion of the Security if the Trustee receives the notice
of revocation before the date the amendment or waiver becomes effective. After
an amendment or waiver becomes effective, it shall bind every Security holder.
An amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only

amendment changes the terms of a Security, the Trustee may require the Holder of

amendment the Trustee shall be entitled to receive indemnity reasonably
satisfactory to it and to receive, and (subject to Section 7.01) shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such amendment is authorized or permitted by this Indenture.

Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

or consent, only Securities which the Trustee knows are so owned shall be so

will pay interest semiannually on                    and                of each
year. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from            , 1998.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

on or before the interest payment date. Holders must surrender Securities to a
Paying Agent to collect principal payments. The Company will pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of
Securities (including principal, premium and interest) will be made by wire
transfer of immediately available funds to the accounts specified by the holders
thereof or, if no U.S. dollar account maintained by the payee with a bank in the
United States is designated by any holder to the Trustee or the Paying Agent at
least 30 days prior to the relevant due date for payment (or such other date as
the Trustee may accept in its discretion), by mailing a check to the registered
address of such holder.

to redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the related interest payment date).

thereof) to be redeemed on the redemption date is deposited with the Paying

satisfied, on and after such date interest ceases to accrue on such Securities
(or such portions thereof) called for redemption.

7.  Put Provisions
    --------------

         Upon a Change of Control, any Holder of Securities will have the right
to cause the Company to repurchase all or any part of the Securities of such
Holder at a repurchase price equal to 101% of the principal amount of the
Securities to be repurchased plus accrued and unpaid interest to the date of
repurchase (subject to the right of holders of record on the relevant record
date to receive interest due on the related interest payment date) as provided

two years, the Trustee or Paying Agent shall pay the money back to the Company

         Under the Indenture, Events of Default include (i) default in payment
of interest on the Securities upon its occurrence prior to                , 2002
and after continuing 30 days thereafter; (ii) default in payment of principal on
the Securities at maturity, upon redemption pursuant to paragraph 5 or 6 of the
Securities, upon acceleration or otherwise, or failure by the Company to redeem
or purchase Securities when required; (iii) failure by the Company to comply
with other agreements in the Indenture or the Securities, in certain cases
subject to notice and lapse of time; (iv) certain accelerations (including
failure to pay within any grace period after final maturity) of other
Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds
$5,000,000; (v) certain events of bankruptcy or insolvency with respect to the
Company or a Significant Subsidiary; (vi) certain judgments or decrees for the
payment of money in excess of $5,000,000; and (vii) the security interest under
the Pledge Agreement ceasing to be in full force and effect. If an Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Securities may declare all the Securities to be due and
payable immediately. Certain events of bankruptcy or insolvency are Events of
Default which will result in the Securities being due and payable immediately
upon the occurrence of such Events of Default.

         Securityholders may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
with hold from Securityholders notice of any continuing Default (except a
Default in payment of principal or interest) if it determines that withholding
notice is in the interest of the Holders.

14.  Trustee Dealings with the Company
     ---------------------------------

         Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may other wise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

15.  No Recourse Against Others
     --------------------------

         A director, officer, employee or stockholder, as such, of the Company
or the Trustee shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. By accepting a Security,
each Securityholder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

18.  CUSIP Numbers

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         NOW, THEREFORE, the parties hereto hereby agree as follows:

         1. Pledge and Grant of Security Interest. The Pledgor hereby pledges to
the Trustee for the ratable benefit of the holders of the Notes, and grants to
the Trustee for the ratable benefit of the holders of the Notes, a continuing
first priority security interest in and to (i) all of the Pledgor's right, title
and interest in the Pledged Securities and the Pledge Account, (ii) all
certificates or other evidence of ownership representing the Pledged Securities
and the Pledge Account and (iii) all products and proceeds of any of the Pledged
Securities, including, without limitation, all dividends, interest, principal
payments, cash, options, warrants, rights, instruments, subscriptions and other
property or proceeds from time to time received, receivable or otherwise
distributed or distributable in respect of or in exchange for any or all of the
Pledged Securities (collectively, the "Collateral").

         2. Security for Obligations. This Pledge Agreement and the Collateral
secure the prompt and complete payment and performance when due (whether at
stated maturity, by acceleration or otherwise) of all of the Obligations.

         3. Delivery of Collateral; Pledge Account; Interest. (a) All
certificates or instruments representing or evidencing the Pledged Securities
shall be delivered to and held by or on behalf of the Trustee pursuant hereto
and shall be in suitable form for transfer and delivery, or shall be accompanied
by instruments of transfer or assignment duly executed in blank all in form
satisfactory to the Trustee, or shall be delivered to the Trustee through the
book-entry facilities of the applicable depositary.

            (b) Concurrently with the execution and delivery of this Pledge
Agreement, the Trustee shall establish an account entitled the "NEON PLEDGE
ACCOUNT" for the deposit of the Pledged Securities (the "Pledge Account") at its
offices at                           . Subject to the other terms and conditions
of this Pledge Agreement, all funds or other property accepted by the Trustee

shall remain on deposit in the Pledge Account until withdrawn in accordance with
this Agreement. If and to the


<PAGE>


                                                                               3


extent the Pledged Securities comprise certificated securities (as defined in
Section 8-102 of the Uniform Commercial Code in the State of New York), such
Pledged Securities shall be registered in the name of the Trustee or its
nominee, as Trustee for the benefit of the holders of the Notes, and possession
thereof shall be maintained by the Trustee within the State of New York.

            (c) All interest earned on or other distributions or amounts paid
with respect to any Collateral shall be retained in the Pledge Account and may
be reinvested by and at the direction of the Pledgor in other Pledged
Securities; provided that the Pledgor may only so reinvest such interest,
distributions or amounts if, based on the report of an internationally
recognized firm of independent public accountants selected by the Pledgor and
addressed to the Trustee, scheduled principal and interest payments on the
Pledged Securities retained in the Pledge Account will result in receipt of
United States dollars in an amount and at a time sufficient to provide for
payment in full when due of each of the Secured Payments (or, in the event any
such Secured Payments have been made, the remaining unpaid Secured Payments).

         4. Disbursements. (a) Not less than three Business Days prior to the
date of any of the Secured Payments, the Pledgor may direct the Trustee in
writing to transfer from the Pledge Account to the Trustee in its capacity as
Paying Agent (or, if applicable, any successor Paying Agent), United States
dollars in immediately available funds necessary to provide for payment in full
of or any portion of the next regularly scheduled interest payment on the Notes.
Upon receipt of such written request, the Trustee shall take such action as is
necessary to provide for the timely payment of such amount of United States
dollars in immediately available funds directly to the Trustee as Paying Agent
(or, if applicable, any successor Paying Agent) from proceeds of the Pledged
Securities held in the Pledge Account.

            (b) If the Pledgor elects to pay any of the Secured Payments (or any
portion thereof) from a source of funds other than the Pledge Account (the
"Pledgor's Funds"), then the Pledgor may on at least two Business Days' prior
written notice, after payment of such Secured Payment or portion thereof
(evidenced by an Officers' Certificate delivered to the Trustee stating that
such regularly scheduled interest payment or portion thereof has been made in
accordance with the terms of the Indenture), direct the Trustee in writing to
release to the Pledgor or as it may direct an amount of funds or Pledged
Securities, at the

                                                                               4


Pledgor's sole option, from the Pledge Account less than or equal to the amount
of Pledgor's Funds so expended, without accounting for any Pledgor's Funds so
expended in payment of Defaulted Interest. Upon receipt of such written
direction from the Pledgor, together with the certificate described in the
preceding sentence, the Trustee shall take such action as is necessary to
provide for the prompt payment to the Pledgor of the amount of funds or Pledged
Securities requested from the Pledge Account.

             (c) If at any time the scheduled payments of principal of and
interest on the Pledged Securities exceeds 100% of the amount in cash
sufficient, based on the report of an internationally recognized firm of
independent certified public accountants selected by the Pledgor and addressed
to the Trustee, to provide for timely payment in full of the Secured Payments
(or, in the event any Secured Payments have been made, an amount in cash
sufficient to provide for timely payment in full of the remaining unpaid Secured
Payments), the Pledgor may direct the Trustee in writing to release to the
Pledgor or as it directs an amount of funds or Pledged Securities, at the
Pledgor's sole option, less than or equal to such excess. Upon receipt of such
written direction from the Pledgor, together with such report of such
internationally recognized firm of independent certified public accountants, the
Trustee shall take such action as is necessary to provide for the prompt payment
to the Pledgor of the amount of funds or Pledged Securities requested from the
Pledge Account.

             (d) Upon payment in full of the Secured Payments, evidenced by an
Officers' Certificate delivered to the Trustee stating that such regularly
scheduled interest payments have been made in full in accordance with the
Indenture, the security interest in the Collateral evidenced by this Pledge
Agreement shall terminate and be of no further force and effect. Furthermore,
upon release of any Collateral from the Pledge Account in accordance with the
terms of this Pledge Agreement, the security interest evidenced by this Pledge
Agreement in the Collateral so released shall terminate and be of no further
force and effect.

         5. Representations and Warranties. The Pledgor hereby represents and
warrants that:

                  (a) the execution, delivery and performance by the Pledgor of

         of the Notes, enforceable as such against all creditors of the Pledgor

         created hereby in the Collateral) or (ii) for the exercise by the
         Trustee of the rights provided for in this Pledge Agreement or the
         remedies in respect of the Collateral pursuant to this Pledge
         Agreement; and

                  (e) the pledge of the Collateral pursuant to this Pledge
         Agreement is not prohibited by any applicable law or government
         regulation, release, interpretation or opinion of the Board of
         Governors of the Federal Reserve System or other regulatory agency in

being granted in order to preserve and protect the security interest of the
holders of Notes in and to the Collateral granted hereby and shall not be
interpreted to, and shall not, impose any duties on the Trustee in connection
therewith other than those imposed under applicable law.

         11. Indemnity. The Pledgor shall indemnify, defend and hold harmless
the Trustee and its directors, officers, agents and employees from and against
all claims, actions, obligations, losses, liabilities and expenses, including
costs, fees and disbursements of counsel, the costs of investigations, and
claims for damages, arising from the Trustee's performance under this Pledge
Agreement, except insofar as the same may have been caused by such indemnified
person's own negligent action, its own negligent failure to act or its own
willful misconduct. The obligations of the Pledgor under this Section 11 shall
survive the resignation or removal of the Trustee and the termination of this
Agreement.

         12. Remedies upon Event of Default. If an Event of Default shall have
occurred:

             (a) The Trustee shall have and may exercise with reference to the
Collateral any or all of the rights and remedies of a secured party under the
UCC in effect in the State of New York, and as otherwise granted herein or under
any other applicable law or under any other agreement now or hereafter in effect
executed by the Pledgor, including, without limitation, the right and power to
sell, at public or private sale or sales, or otherwise dispose of, or otherwise
utilize the Collateral and any part or parts thereof, in any manner authorized
or permitted under said UCC after default by a debtor, and to apply the proceeds
thereof toward payment of any costs and expenses and attorneys' fees and
expenses thereby incurred by the Trustee and toward payment of the Obligations
in such order or manner as the Trustee may elect. Specifically, and without
limiting the foregoing, the Trustee shall have the right to take possession of
all or any part of the Collateral or any security therefor and of all books,
records, papers and documents of the Pledgor or in the Pledgor's possession or
control relating to the Collateral that are not already in the Trustee's
possession, and for such purposes may enter upon any premises upon which any of
the Collateral or any security therefor or any of said books, records, papers
and documents are situated and remove the same therefrom without any liability
for trespass or damages thereby occasioned. To the extent permitted by law, the
Pledgor expressly waives any notice of sale or other disposition of the
Collateral and all other rights or remedies of the Pledgor or


<PAGE>


                                                                               9


formalities prescribed by law relative to sale or disposition of the Collateral
or exercise of any other right or remedy of the Trustee existing after Default
or Event of Default hereunder. To the extent any such notice is required and
cannot be waived, the Pledgor agrees that if such notice is given in the manner
provided in Section 17 hereof at least three days before the time of the sale or
disposition, such notice shall be deemed reasonable and shall fully satisfy any
requirement for giving of said notice. The Trustee shall not be obligated to
make any sale of Collateral regardless of notice of sale having been given. The
Trustee may adjourn any public or private sale. The Pledgor further agrees to
use its best efforts to do or cause to be done all such other acts as may be
necessary to effect the intention of this Section 12.

             (b) All rights to marshalling of assets of the Pledgor, including
any such right with respect to the Collateral, are hereby waived by the Pledgor.
The Pledgor shall not contest or support any other person in contesting the
validity or priority of the security interests created under this Pledge
Agreement.

             (c) Any money collected by the Trustee pursuant to this Section 12
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
(or premium, if any) or interest, upon presentation of the Notes and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

                  (i) FIRST: to the payment of the amounts then due and unpaid
         for interest on the Notes, ratably, without preference or priority of
         any kind, according to the amounts due and payable on such Notes for
         interest; and

                  (ii) SECOND: to the payment of the amounts then due and unpaid
         for principal of (and premium, if any) on the Notes, ratably without
         preference or priority of any kind, according to the amounts due and
         payable on such Notes for principal (and premium, if any); and

                  (iii) THIRD: to the payment of all amounts due the Trustee
         under Sections 11 and 13 of the Pledge Agreement; and

                  (iv) FOURTH:  to the Pledgor.

         The Trustee may fix a record date and payment date for any payment to
holders of the Notes pursuant to this Section 12. At least 15 calendar days
before such record

                                                                              10


date, the Trustee at the expense of the Pledgor shall send to each holder of a
Note by first class mail, postage prepaid, a notice prepared by the Pledgor that
states such record date, the payment date and amount to be paid.

         13. Fees and Expenses. The Pledgor shall, upon demand, pay to the
Trustee the amount of its fees (which shall be in an amount previously agreed to
by the Pledgor and the Trustee) and any and all reasonable expenses (including,
without limitation, the reasonable fees, expenses and disbursements of counsel,
experts and agents retained by the Trustee) that the Trustee may incur in
connection with (i) the administration of this Pledge Agreement, (ii) the
custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Collateral, (iii) the exercise or enforcement of
any of the rights of the Trustee and the holders of the Notes hereunder or (iv)
the failure by the Pledgor to perform or observe any of the provisions hereof.
The obligations of the Pledgor under this Section 13 shall survive the
resignation or removal of the Trustee and the termination of this Agreement.

         14. Security Interest Absolute. All rights of the Trustee and the
holders of the Notes, and the security interests created hereunder, and all
obligations of the Pledgor hereunder, shall be absolute and unconditional
irrespective of:

                  (a) any lack of validity or enforceability of the
         Indenture or any other agreement or instrument relating
         thereto;

                  (b) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Obligations, or any other
         amendment or waiver of or any consent to any departure from the
         Indenture;

                  (c) any exchange, surrender, release or
         nonperfection of any Liens on any other collateral for
         all or any of the Obligations; or

                  (d) any other circumstance that might otherwise constitute a
         defense available to, or a discharge of, the Pledgor in respect of the
         Obligations or of this Pledge Agreement.

         15. Continuing Security Interest; Termination. (a) This Pledge
Agreement shall create a continuing security interest in and to the Collateral
and shall, unless otherwise provided in the Indenture or in this Pledge


<PAGE>


                                                                              11


Agreement, remain in full force and effect until the earlier of payment in full
in cash of (i) each of the Secured Payments to the holders thereof under the
terms of the Indenture or (ii) all Obligations due and owing under the Indenture
and the Notes in the event such Obligations become payable prior to the payment
of any of the Secured Payments. This Pledge Agreement shall be binding upon the
Pledgor, its successors and assigns, and shall inure, together with the rights
and remedies of the Trustee hereunder, to the benefit of the Trustee and the
holders of the Notes and their respective successors, transferees and assigns.

             (b) This Pledge Agreement shall terminate upon the earlier of (i)
payment in full in cash of each of the Secured Payments to the holders thereof
under the terms of the Indenture or (ii) the date on which all Obligations due
and owing under the Indenture and the Notes have been paid in full in the event
such Obligations become payable prior to the payment of any of the Secured
Payments. At such time, the Trustee shall, at the written request of the
Pledgor, reassign and redeliver to the Pledgor all of the Collateral hereunder
that has not been sold, disposed of, retained or applied by the Trustee in
accordance with the terms of this Pledge Agreement and the Indenture. Such
reassignment and redelivery shall be without warranty (either express or
implied) by or recourse to the Trustee, except as to the absence of any prior
assignments by the Trustee of its interest in the Collateral, and shall be at
the expense of the Pledgor.

         16. Authority of the Trustee. (a) The Trustee shall have and be
entitled to exercise all powers hereunder that are specifically granted to the
Trustee by the terms hereof, together with such powers as are reasonably
incident thereto. The Trustee may perform any of its duties hereunder or in
connection with the Collateral by or through agents or employees and shall be
entitled to retain counsel and to act in reliance upon the advice of counsel
concerning all such matters. None of the Trustee or any director, officer,
employee, attorney or agent of the Trustee shall be liable to the Pledgor for
any action taken or omitted to be taken by it or them hereunder, except for its
or their own negligent action, negligent failure to act or willful misconduct;
provided that (i) each such person shall not be liable for any error of judgment
made in good faith by it unless it is proved that such person was negligent in
ascertaining the pertinent facts and (ii) the Trustee shall not be liable with
respect to any action it takes or omits to take in good faith in accordance with
a direction or request received by it pursuant to Section 6.05 of the Indenture
or Section 16(d) hereof. The Trustee shall not be


<PAGE>


                                                                              12


responsible for the validity, effectiveness or sufficiency hereof or of any
document or security furnished pursuant hereto. The Trustee and its directors,
officers, employees, attorneys and agents shall be entitled to rely on any
communication, instrument or document believed by it or them to be genuine and
correct and to have been signed or sent by the proper Person or Persons.

             (b) The Pledgor acknowledges that the rights and responsibilities
of the Trustee under this Pledge Agreement with respect to any action taken by
the Trustee or the exercise or nonexercise by the Trustee of any option, right,
request, judgment or other right or remedy provided for herein or resulting or
arising out of this Pledge Agreement shall, as between the Trustee and the
holders of the Notes, be governed by the Indenture and by such other agreements
with respect thereto as may exist from time to time among them, but, as between
the Trustee and the Pledgor, the Trustee shall be conclusively presumed to be
acting as agent for the holders of the Notes with full and valid authority so to
act or refrain from acting, and the Pledgor shall not be obligated or entitled
to make any inquiry respecting such authority.

             (c) The Trustee undertakes to perform such duties and only such
duties as are specifically set forth in this Agreement and no implied covenants
or obligations shall be read in this Agreement against the Trustee. The Trustee
shall not be deemed to have knowledge of a Default or an Event of Default under
the Indenture unless informed in writing by the Pledgor or the holder of any
Note or unless a Trust Officer shall have actual knowledge thereof.

             (d) The Trustee shall not be required to exercise any remedies
hereunder unless requested in writing to do so by the holders of not less than a
majority in principal amount of the outstanding Notes and only if furnished with
indemnity satisfactory to the Trustee. The Trustee may consult with counsel and
shall not be liable for any action taken in good faith in reliance upon advice
of counsel except for its bad faith, its own negligent action, its own negligent
failure to act or its own wilful misconduct. The Trustee makes no representation
or warranty and shall have no responsibility concerning the value or validity of
the Collateral or the validity or perfection of the pledge thereof.

             (e) Any resignation or removal of the Trustee under the Indenture
shall result in the simultaneous resignation or removal, as the case may be, of
the Trustee hereunder and any appointment of a successor Trustee under


<PAGE>


                                                                              13


the Indenture shall result in the simultaneous appointment of the same successor
Trustee hereunder.

             (f) The Trustee shall be deemed to have exercised reasonable care
in the custody and preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to that which a reasonable
person accords its own property, it being understood that neither the Trustee
nor the holders of the Notes shall have responsibility for (i) ascertaining or
taking action with respect to calls, conversions, exchanges, maturities, tenders
or other matters relative to any Collateral, whether or not any such Person has
or is deemed to have knowledge of such matters, or (ii) taking any necessary
steps to preserve rights against any parties with respect to any Collateral.

             (g) Notwithstanding anything herein to the contrary, the
exculpations, immunities and protections available to the Trustee under the
Indenture shall be available to the Trustee hereunder.

         17. Notices. Any communication, notice or demand to be given hereunder
shall be in writing and delivered in person or mailed by first class mail,
postage prepaid, addressed as follows: If to the Trustee:                      ;
if to the Company:                                         . Notice may also be
given in such other form and manner or to such other address as shall be
designated by any party hereto to each other party hereto in a written notice
delivered in accordance with the terms of the Indenture.

         18. No Waiver; Cumulative Rights. No failure on the part of the Trustee
to exercise, and no delay in exercising, any right, remedy or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise by
the Trustee of any right, remedy or power hereunder preclude any other or future
exercise of any other right, remedy or power. Each and every right, remedy and
power hereby granted to the Trustee or allowed it by law or other agreement
shall be cumulative and not exclusive the one of any other, and may be exercised
by the Trustee from time to time.

         19. Benefits of Pledge Agreement. Nothing in this Pledge Agreement,
whether express or implied, shall give to any Person other than the parties
hereto and their successors hereunder, and the holders of the Notes, any benefit
or any legal or equitable right, remedy or claim under this Pledge Agreement.

         20. Applicable Law. THIS PLEDGE AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL 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 LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         21. Calculation of Interest. For purposes of this Agreement, all
calculations of the Secured Payments shall be calculated on the basis of a
360-day year of 12 30-day months, with interest accruing on the Notes at the
rate of   % per annum and being payable semiannually in arrears on             ,
and                     of each year, and interest on overdue installments of
interest, to the extent lawful, accruing at the rate of % per annum. References

         23. Settlement. Amounts, if any, held in the Pledge Account pending
settlement of purchase of the Pledged Securities shall constitute Collateral
hereunder, shall be held by the Trustee for the benefit of the holders of the
Notes and a portion thereof equal to the aggregate price paid for such Pledged
Securities shall be released by the Trustee (without further direction or
instruction required from any other party hereto) against delivery of such
Pledged Securities, and any excess funds remaining in the Pledge Account after
giving effect to such settlement shall be promptly forwarded to the Pledgor at

July 28, 1998


NorthEast Optic Network, Inc.
391 Totten Pond Road, Suite 401
Waltham, Massachusetts  02154

Ladies and Gentlemen:

     This opinion is furnished to you in connection with a Registration
Statement on Form S-1 (the "Registration Statement") filed with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Securities Act"), for the registration of (i) 6,325,000 shares of
Common Stock, $.01 par value per share (the "Shares"), of NorthEast Optic
Network, Inc., a Delaware Corporation (the "Company"), including 825,000 Shares
issuable upon exercise of an overallotment option granted by the Company and
(ii) $165,000,000 aggregate principal amount of Senior Notes due 2008
("Debentures").

     The Shares are to be sold by the Company and certain selling stockholders
pursuant to an underwriting agreement (the "Equity Underwriting Agreement"), to
be entered into by and among the Company, the selling stockholders, and Credit
Suisse First Boston Corporation and Warburg Dillon Read LLC, as representatives
of the several underwriters named in the Equity Underwriting Agreement. The
Debentures are to be sold by the Company pursuant to an underwriting agreement
(the "Debt Underwriting Agreement") to be entered into by and among the Company
and Credit Suisse First Boston Corporation and Warburg Dillon Read LLC.

     We have examined signed copies of the Registration Statement and all
exhibits thereto, all as filed with the Commission. We have also examined and
relied upon the original or copies of minutes of the meetings of the
stockholders and the Board of Directors of the Company, stock record books of
the Company, a copy of the ByLaws of the Company, as amended, a copy of the
Certificate of Incorporation of the Company, as amended, and such other
documents as we have deemed necessary for purposes of rendering the opinions
hereinafter set forth.

     In our examination of the foregoing documents, we have assumed the
genuineness of all signatures and the authenticity of all documents submitted to
us as originals, the conformity to original documents of all documents submitted
to us as copies, and the authenticity of the originals of such documents. Our
opinion expressed below with respect to the Debentures being binding obligations
of the Company is

qualified to the extent that it may be subject to or affected by (i) applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other
laws relating to or affecting the rights of creditors generally, (ii) statutory
or decisional law concerning recourse by creditors to security in the absence of
notice and hearing, and (iii) duties and standards imposed on creditors,
including, without limitation, requirements of good faith, reasonableness and
fair dealing.

     We assume that the appropriate action will be taken, prior to the offer and
sale of the Shares and Debentures, to register and qualify the Shares and
Debentures for sale under all applicable state securities or "blue sky" laws.

     Based upon and subject to the foregoing, we are of the opinion that the
Shares and Debentures have been duly authorized and, when issued and sold
pursuant to the Equity Underwriting Agreement and the Debt Underwriting
Agreement, respectively, (i) such Shares and Debentures will be validly issued,
fully paid and nonassessable and (ii) such Debentures will be binding
obligations of the Company.

     We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement and to the use of our name therein and in
the related Prospectuses under the caption "Legal Matters." In giving such
consent, we do not hereby admit that we are in the category of persons whose
consent is required under Section 7 of the Securities Act or the rules and
regulations of the Commission.

     It is understood that this opinion is to be used only in connection with
the offer and sale of the Shares and Debentures while the Registration Statement
is in effect.

     This opinion is based upon currently existing statutes, rules, regulations
and judicial decisions, and we disclaim any obligations to advise you of any
change in any of these sources of law or subsequent legal or factual
developments which might affect any matters or opinions set forth herein.

     Please note that we are opining only as to the matters expressly set forth
herein, and no opinion should be inferred as to any other matters.

                                              Very truly yours,

                                              /s/ Hale and Dorr LLP

                                              HALE AND DORR LLP




                          NORTHEAST OPTIC NETWORK, INC.

                 AMENDED AND RESTATED 1998 STOCK INCENTIVE PLAN


1.   Purpose
     -------

     The purpose of this 1998 Stock Incentive Plan (the "Plan") of NorthEast
Optic Network, Inc., a Delaware corporation (the "Company"), is to advance the
interests of the Company's shareholders by enhancing the Company's ability to
attract, retain and motivate persons who make (or are expected to make)
important contributions to the Company by providing such persons with equity
ownership opportunities and performance-based incentives and thereby better
aligning the interests of such persons with those of the Company's shareholders.
Except where the context otherwise requires, the term "Company" shall include
any present or future subsidiary corporations of NorthEast Optic Network, Inc.,
as defined in Section 424(f) of the Internal Revenue Code of 1986, as amended,
and any regulations promulgated thereunder (the "Code").

2.   Eligibility
     -----------

     All of the Company's employees, officers, directors, consultants and
advisors are eligible to be granted options, restricted stock, or other
stock-based awards (each, an "Award") under the Plan. Any person who has been
granted an Award under the Plan shall be deemed a "Participant".

3.   Administration, Delegation
     ---------------------------

     (a) Administration by Board of Directors. The Plan will be administered by
the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. No member of the Board shall be liable for any action
or determination relating to the Plan. All decisions by the Board shall be made
in the Board's sole discretion and shall be final and binding on all persons
having or claiming any interest in the Plan or in any Award. No director or
person acting pursuant to the authority delegated by the Board shall be liable
for any action or determination under the Plan made in good faith.




<PAGE>



     (b) Delegation to Executive Officers. To the extent permitted by applicable
law, the Board may delegate to one or more executive officers of the Company the
power to make Awards and exercise such other powers under the Plan as the Board
may determine, provided that the Board shall fix the maximum number of shares
subject to Awards and the maximum number of shares for any one Participant to be
made by such executive officers.

     (c) Appointment of Committees. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). At such time as the
common stock, $.01 par value per share, of the Company (the "Common Stock") is
registered under the Securities Exchange Act of 1934 (the "Exchange Act"), the
Board shall appoint one such Committee of not less than two members, each member
of which shall be an "outside director" within the meaning of Section 162(m) of
the Code and a "non-employee director" as defined in Rule 16b-3 promulgated
under the Exchange Act." All references in the Plan to the "Board" shall mean a
Committee or the Board or the executive officer referred to in Section 3(b) to
the extent that the Board's powers or authority under the Plan have been
delegated to such Committee or executive officer.

4.   Stock Available for Awards
     --------------------------

     (a) Number of Shares. Subject to adjustment under Section 4(c), Awards may
be made under the Plan for up to 2,436,105 shares of Common Stock (after giving
effect to a 2.5-for-1 stock split effected by means of a stock dividend on or
about July 29, 1998). If any Award expires or is terminated, surrendered or
canceled without having been fully exercised or is forfeited in whole or in part
or results in any Common Stock not being issued, the unused Common Stock covered
by such Award shall again be available for the grant of Awards under the Plan,
subject, however, in the case of Incentive Stock Options (as hereinafter
defined), to any limitation required under the Code. Shares issued under the
Plan may consist in whole or in part of authorized but unissued shares or
treasury shares.

     (b) Per-Participant Limit. Subject to adjustment under Section 4(c), for
Awards granted after the Common Stock is registered under the Exchange Act, the
maximum number of shares with respect to which an Award may be granted to any
participant under the Plan shall be 100,000 per calendar year. The
per-Participant limit described in this Section 4(b) shall be construed and
applied consistently with Section 162(m) of the Code.

     (c) Adjustment to Common Stock. In the event of any stock split, stock
dividend, recapitalization, reorganization, merger, consolidation, combination,
exchange of shares, liquidation, spin-off or other similar change in
capitalization or 

                                      - 2 -

<PAGE>



event, or any distribution to holders of Common Stock other than a normal cash
dividend, (i) the number and class of securities available under this Plan, (ii)
the number and class of security and exercise price per share subject to each
outstanding Option, (iii) the repurchase price per security subject to each
outstanding Restricted Stock Award, and (iv) the terms of each other outstanding
stock-based Award shall be appropriately adjusted by the Company (or substituted
Awards may be made, if applicable) to the extent the Board shall determine, in
good faith, that such an adjustment (or substitution) is necessary and
appropriate. If this Section 4(c) applies and Section 8(e)(1) also applies to
any event, Section 8(e)(1) shall be applicable to such event, and this Section
4(c) shall not be applicable.

5.   Stock Options
     -------------

     (a) General. The Board may grant options to purchase Common Stock (each, an
"Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

     (b) Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c) Exercise Price. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement.

     (d) Duration of Options. Each Option shall be exercisable at such times and
subject to such terms and conditions as the Board may specify in the applicable
option agreement.

     (e) Exercise of Option. Options may be exercised only by delivery to the
Company of a written notice of exercise signed by the proper person together
with payment in full as specified in Section 5(f) for the number of shares for
which the Option is exercised.

     (f) Payment Upon Exercise. Common Stock purchased upon the exercise of 


                                      - 3 -

<PAGE>


an Option granted under the Plan shall be paid for as follows:

          (1) in cash or by check, payable to the order of the Company;

          (2) except as the Board may otherwise provide in an Option, delivery
of an irrevocable and unconditional undertaking by a credit worthy broker to
deliver promptly to the Company sufficient funds to pay the exercise price, or
delivery by the Participant to the Company of a copy of irrevocable and
unconditional instructions to a credit worthy broker to deliver promptly to the
Company cash or a check sufficient to pay the exercise price;

          (3) (i) by delivery of shares of Common Stock owned by the Participant
valued at their fair market value as determined by the Board in good faith
("Fair Market Value"), which Common Stock was owned by the Participant at least
six months prior to such delivery, (ii) by delivery of a promissory note of the
Participant to the Company on terms determined by the Board, or (iii) by payment
of such other lawful consideration as the Board may determine; or

          (4) any combination of the above permitted forms of payment.

6.   Restricted Stock
     ----------------

     (a) Grants. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, "Restricted Stock Award").

     (b) Terms and Conditions. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

<PAGE>



7.   Other Stock-Based Awards
     ------------------------

     The Board shall have 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.

8.   General Provisions Applicable to Awards
     ---------------------------------------

     (a) Transferability of Awards. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

     (b) Documentation. Each Award under the Plan shall be evidenced by a
written instrument in such form as the Board shall determine. Each Award may
contain terms and conditions in addition to those set forth in the Plan.

     (c) Board Discretion. Except as otherwise provided by the Plan, each type
of Award may be made alone in addition or in relation to any other type of
Award. The terms of each type of Award need not be identical, and the Board need
not treat Participants uniformly.

     (d) Termination of Status. The Board shall determine the effect on an Award
of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e) Extraordinary Corporate Transactions.

          (1) Change in Control. A "Change of Control of the Company" (as
defined in Section 9) shall have the effects set forth in Section 9.

          (2) Assumption of Options Upon Certain Events. The Board may grant
Awards under the Plan in substitution for stock and stock-based awards held by
employees of another corporation who become employees of the Company as a result
of a merger or consolidation of the employing corporation with the Company or
the 


                                      - 5 -

<PAGE>



acquisition by the Company of property or stock of the employing corporation.
The substitute Awards shall be granted on such terms and conditions as the Board
considers appropriate in the circumstances.

     (f) Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. The Board may allow Participants to
satisfy such tax obligations in whole or in part in shares of Common Stock,
including shares retained from the Award creating the tax obligation, valued at
their Fair Market Value. The Company may, to the extent permitted by law, deduct
any such tax obligations from any payment of any kind otherwise due to a
Participant.

     (g) Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (h) Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (i) Acceleration. The Board may at any time provide that any Options shall
become immediately exercisable in full or in part, that any Restricted Stock
Awards shall be free of all restrictions or that any other stock-based Awards
may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be.

9.   Change in Control
     -----------------

     (a) Acceleration. Notwithstanding any other provision of the Plan and
except as otherwise provided in the relevant option agreement, in the event of a
"Change in 


                                      - 6 -

<PAGE>

Control of the Company" (as defined below), the exercise dates of all Options
(or the vesting of all Restricted Stock Awards or other stock based Awards, as
the case may be) granted to such Participant then outstanding shall be
accelerated in full and any restrictions on exercising outstanding options or
other Awards issued to such Participant pursuant to the Plan shall terminate.
For purposes of the Plan, the term "Change in Control of the Company" shall have
the following meaning: A "Change in Control of the Company" shall occur or be
deemed to have occurred only if (i) any "person", as such term is used in
Sections 13(d) and 14(d) of the Exchange Act (other than the Company, any
trustee or other fiduciary holding securities under an employee benefit plan of
the Company, or any corporation owned directly or indirectly by the stockholders
of the Company in substantially the same proportion as their ownership of stock
of the Company), becomes (after the date of the adoption of this Plan) the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing 50% or more of the
combined voting power of the Company's then outstanding securities; (ii) during
any period of two consecutive years ending during the term of the Plan (not
including any period prior to the adoption of the Plan), individuals who at the
beginning of such period constitute the Board of Directors of the Company, and
any new director (other than a director designated by a person who has entered
into an agreement with the Company to effect any transaction described in clause
(i), (iii) or (iv) of this Section 9) whose election by the Board of Directors
or nomination for election by the Company's stockholders was approved by a vote
of at least two-thirds of the directors then still in office who were either
directors at the beginning of the period or whose election or whose nomination
for election was previously so approved, cease for any reason to constitute a
majority of the Board of Directors; (iii) the stockholders of the Company
approve a merger or consolidation of the Company with any other corporation,
other than (A) a merger or consolidation which would result in the voting
securities of the Company outstanding immediately prior thereto continuing to
represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) more than 50% of the combined voting power
of the voting securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation or (B) a merger or consolidation
effected to implement a recapitalization of the Company (or similar transaction)
in which no "person" (as hereinabove defined) acquires more than 50% of the
combined voting power of the Company's then outstanding securities; or (iv) the
stockholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of all or
substantially all of the Company's assets.

     (b) Consequences of Change in Control of the Company. Upon the occurrence
of a Change in Control of the Company, or the execution by the Company of any
agreement which results in a Change in Control of the Company, the Board shall
take any one or more of the following actions with respect to then outstanding
Awards: 


                                      - 7 -

<PAGE>



(i) provide that outstanding Options shall be assumed, or equivalent Options
shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof), provided that any such Options substituted for Incentive
Stock Options shall satisfy, in the determination of the Board, the requirements
of Section 424(a) of the Code; (ii) in the event of a transaction resulting in a
Change in Control of the Company under the terms of which holders of Common
Stock will receive upon consummation thereof a cash payment for each share of
Common Stock surrendered pursuant to such transaction (the "Acquisition Price"),
provide that all outstanding Options shall terminate upon consummation of such
transaction and that Participants shall receive, in exchange therefor, a cash
payment equal to the amount (if any) by which (A) the Acquisition Price
multiplied by the number of shares of Common Stock subject to such outstanding
Options (whether or not then exercisable), exceeds (B) the aggregate exercise
price of such Options; and (iii) provide that any other stock-based Awards
outstanding shall be assumed, or equivalent Awards shall be substituted, by the
acquiring or succeeding corporation (or an affiliate thereof).

10.  Miscellaneous
     -------------

     (a) No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b) No Rights As Stockholder. Subject to the provisions of the applicable
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.

     (c) Effective Date and Term of Plan. The Plan shall become effective on the
later of (i) date on which it is adopted by the Board and (ii) the date of the
closing of the IPO. No Awards shall be granted under the Plan after the
ocompletion of ten years from the earlier of (i) the date on which the Plan was
adopted by the Board or (ii) the date the Plan was approved by the Company's
shareholders, but Awards previously granted may extend beyond that date.

     (d) Amendment of Plan. The Board may amend, suspend or terminate the Plan
or any portion thereof at any time, provided that no amendment shall be made
without stockholder approval if such approval is necessary to comply with any
applicable tax or regulatory requirements. Amendments requiring stockholder
approval shall become effective when adopted by the Board, but no Award granted
to a 



                                      - 8 -

<PAGE>

Participant designated as subject to Section 162(m) by the Board shall become
exercisable, realizable or vested (to the extent that such amendment to the Plan
was required to grant such Award to a particular Participant) unless and until
such amendment shall have been approved by the Company's shareholders.

     (e) Governing Law. The provisions of the Plan and all Awards made hereunder
shall be governed by and interpreted in accordance with the laws of the State of
Delaware, without regard to any applicable conflicts of law.

     (f) Stockholder Approval. For purposes of the Plan, stockholder approval
shall mean approval by a vote of Stockholders in accordance with Section 162(m)
of the Code.

payments hereunder to the Company shall include such amount (the "Gross-Up") as
is necessary to hold the Company harmless on an after-Tax basis from all Taxes,

Federal, state and local, domestic and foreign, income, franchise, property,
sales, excise, employment, payroll, social security, value-added, ad valorem,

whatsoever, including any interest, penalties or additions with respect thereto.
