PROSPECTUS
 
                               NETWORK PLUS CORP.
                          OFFER TO EXCHANGE ONE SHARE OF
              13.5% SERIES A1 CUMULATIVE PREFERRED STOCK DUE 2009
                         FOR EACH OUTSTANDING SHARE OF
               13.5% SERIES A CUMULATIVE PREFERRED STOCK DUE 2009
 
                           ------------------------

        Network Plus Corp., a Delaware corporation ("Network Plus" or the
"Company"), hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and the accompanying Letter of Transmittal (which
together constitute the "Exchange Offer"), to exchange up to 40,000 shares of
its 13.5% Series A1 Cumulative Preferred Stock Due 2009 (the "New Preferred
Shares") for up to 40,000 shares of its outstanding 13.5% Series A Cumulative
Preferred Stock Due 2009 (the "Original Preferred Shares", and, together with
the New Preferred Shares, the "Series A Preferred Stock") that were issued in a
transaction exempt from registration under the Securities Act of 1933, as
amended (the "Securities Act").
 
        The terms of the New Preferred Shares are substantially identical in all
respects to the terms of the Original Preferred Shares for which they may be
exchanged pursuant to the Exchange Offer, except that (i) the offer of the New
Preferred Shares will have been registered under the Securities Act and,
therefore, the New Preferred Shares will be freely transferable by holders
thereof (except as provided below) and not bear a legend regarding restrictions
on transfer, (ii) holders of the New Preferred Shares will not be entitled to
certain rights of the holders of the Original Preferred Shares under the
Registration Agreement (as defined), which rights with respect to the Original
Preferred Shares will terminate on consummation of the Exchange Offer and (iii)
the New Preferred Shares will not contain any provisions regarding the payment
of Special Dividends (as defined).
 
        Dividends on each New Preferred Share will accrue from the last date on
which dividends were paid on the Original Preferred Share surrendered in
exchange therefor or, if no dividends have been paid on such Original Preferred
Share, from the date of original issuance of such Original Preferred Share.
Dividends on the New Preferred Shares will accrue at a rate of 13.5% per annum
of the Specified Amount (as defined) and will be payable quarterly in arrears on
March 1, June 1, September 1 and December 1 of each year, commencing December 1,
1998. Dividends will be payable in cash, except that on each dividend payment
date occurring on or prior to September 1, 2003, dividends may be paid, at the
Company's option, either in cash or by allowing such dividends ("Accumulated
Dividends") to be added to the Specified Amount, which shall initially be equal
to the liquidation preference.
 
        The New Preferred Shares will be redeemable at the option of the
Company, in whole or in part, at any time on or after September 1, 2003, at the
redemption prices set forth herein, plus accumulated and unpaid dividends
thereon, if any, to the redemption date. The New Preferred Shares will be
subject to mandatory redemption on September 1, 2009. In addition, the Company
is required to use all or a specified portion of the proceeds of any Senior
Notes Offering or Public Equity Offering (each as defined) to redeem the New
Preferred Shares at the redemption prices and upon the terms set forth herein.
See "Description of the Series A Preferred Stock--Optional Redemption" and
"Description of the Series A Preferred Stock--Mandatory Redemption".
 
        The Company is a holding company that conducts substantially all its
operations through subsidiaries, and the New Preferred Shares will be
effectively subordinated to all obligations of the Company's subsidiaries
(including trade payables). The Certificate of Designation permits the Company
and its subsidiaries to incur substantial amounts of additional debt and other
liabilities. See "Description of the Series A Preferred Stock".
 
        The Original Preferred Shares were originally issued and sold on
September 3, 1998 in a transaction exempt from registration under the Securities
Act (the "Initial Offering"). Accordingly, the Original Preferred Shares may not
be reoffered, resold or otherwise pledged, hypothecated or transferred in the
United States unless registered under the Securities Act or unless an applicable
exemption from the registration requirements of the Securities Act is available.
The New Preferred Shares are being offered hereunder to satisfy certain
obligations of the Company under the Registration Agreement (as defined). Based
upon interpretations by the Staff (the "Staff") of the Securities and Exchange
Commission (the "Commission") issued to third parties, the Company believes that
the New Preferred Shares issued pursuant to the Exchange Offer in exchange for
the Original Preferred Shares may be offered for resale, resold and otherwise
transferred by holders thereof (other than any holder which is (i) an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act, (ii) a broker-dealer who acquired Original Preferred Shares directly from
the Company or (iii) a broker-dealer who acquired Original Preferred Shares as a
result of market making or other trading activities) without compliance with the
registration and prospectus delivery provisions of the Securities Act provided
that such New Preferred Shares are acquired in the ordinary course of such
holders' business and such holders are not engaged in, and do not intend to
engage in, and have no arrangement or understanding with any person to
participate in, a distribution of such New Preferred Shares. Each broker-dealer
that receives New Preferred Shares for its own account pursuant to the Exchange
Offer must acknowledge that it will deliver a prospectus in connection with any
resale of such New Preferred Shares. The Letter of Transmittal accompanying this
Prospectus (the "Letter of Transmittal") states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. This Prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of New Preferred Shares received in
exchange for Original Preferred Shares where such New Preferred Shares were
acquired by such broker-dealer as a result of market-making activities or other
trading activities. The Company has agreed that, for a period ending 90 days
after the completion of this Exchange Offer, it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution".
 
        The Original Preferred Shares and the New Preferred Shares constitute
new issues of securities with no established trading market. Any Original
Preferred Shares not tendered and accepted in the Exchange Offer will remain
outstanding. To the extent that Original Preferred Shares are tendered and
accepted in the Exchange Offer, a holder's ability to sell untendered, and
tendered but unaccepted, Original Preferred Shares could be adversely affected.
Following consummation of the Exchange Offer, the holders of Original Preferred
Shares will continue to be subject to the existing restrictions on transfer
thereof and the Company will have no further obligation to such holders to
provide for the registration under the Securities Act of the Original Preferred
Shares except under certain limited circumstances. See "Registration Rights". No
assurance can be given as to the liquidity of the trading market for either the
Original Preferred Shares or the New Preferred Shares.
 
        The Company will not receive any proceeds from the issuance of New
Preferred Shares in the Exchange Offer. The Exchange Offer is not conditioned
upon any minimum number of Original Preferred Shares being tendered for
exchange. The Exchange Offer will expire at 5:00 p.m., New York City time, on
               , 1998, unless extended (the "Expiration Date"). The date of
acceptance for exchange of the Original Preferred Shares (the "Exchange Date")
will be the first business day following the Expiration Date, upon surrender of
the Original Preferred Shares. Original Preferred Shares tendered pursuant to
the Exchange Offer may be withdrawn at any time prior to the Expiration Date;
otherwise such tenders are irrevocable.

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

     SEE "RISK FACTORS" BEGINNING ON PAGE 14 FOR A DESCRIPTION OF CERTAIN
FACTORS THAT SHOULD BE CONSIDERED BY PARTICIPANTS IN THE EXCHANGE OFFER.

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

  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
       EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
           SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
      COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.
           ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                              NOTICE TO INVESTORS
 
     Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that the New Preferred Shares issued pursuant to
the Exchange Offer in exchange for Original Preferred Shares may be offered for
resale, resold and otherwise transferred by a holder thereof without compliance
with the registration and prospectus delivery provisions of the Securities Act,
provided that the holder is acquiring the New Preferred Shares in the ordinary
course of its business, is not participating and has no arrangement or
understanding with any person to participate in the distribution of the New
Preferred Shares and is not an "affiliate" of the Company within the meaning of
Rule 405 of the Securities Act. Holders of Original Preferred Shares wishing to
accept the Exchange Offer must represent to the Company that such conditions
have been met. Each broker-dealer who holds Original Preferred Shares acquired
for its own account as a result of market-making or other trading activities and
who receives New Preferred Shares for its own account in exchange for such
Original Preferred Shares pursuant to the Exchange Offer must acknowledge that
it will deliver a prospectus in connection with any resale of such New Preferred
Shares. The Company believes that none of the registered holders of the Original
Preferred Shares is an "affiliate" (as such term is defined in Rule 405 under
the Securities Act) of the Company.
 
     This Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of New Preferred
Shares received in exchange for Original Preferred Shares acquired by such
broker-dealer as a result of market-making or other trading activities. The
Letter of Transmittal states that by acknowledging that it will deliver a
prospectus in connection with any resale of such New Preferred Shares, and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. The Company has
agreed to make this Prospectus (as it may be amended or supplemented) available
to any such broker-dealer that requests copies of such Prospectus in the Letter
of Transmittal for use in connection with any such resale for a period of up to
90 days after the completion of this Exchange Offer. See "Plan of Distribution".
 
     Prior to the Exchange Offer, there has been no public market for the New
Preferred Shares. There can be no assurance as to the liquidity of any markets
that may develop for the New Preferred Shares, the ability of holders to sell
the New Preferred Shares, or the price at which holders would be able to sell
the New Preferred Shares. The Company does not intend to apply for listing of
the New Preferred Shares for trading on any securities exchange or for inclusion
of the New Preferred Shares in any automated quotation system. The National
Association of Securities Dealers, Inc. ("NASD") has designated the Original
Preferred Shares as securities eligible for trading in the Private Offerings,
Resales and Trading through Automatic Linkages ("PORTAL") market of the NASD and
the Company has been advised that Goldman, Sachs & Co., Lehman Brothers Inc. and
Merrill Lynch, Pierce, Fenner & Smith Incorporated have heretofore acted as
market makers for the Original Preferred Shares. The Company has been advised by
each of the aforesaid market makers that it currently intends to make a market
in the New Preferred Shares. Future trading prices of the New Preferred Shares
will depend on many factors, including, among other things, prevailing interest
rates, the Company's operating results and the market for similar securities.
Historically, the market for securities similar to the New Preferred Shares has
been subject to disruptions that have caused substantial volatility in the
prices of such securities. There can be no assurance that any market for the New
Preferred Shares, if such market develops, will not be subject to similar
disruptions. See "Risk Factors -- Absence of Public Market".
 
     The Company will not receive any proceeds from, and has agreed to bear the
expenses of, the Exchange Offer. No underwriter is being used in connection with
the Exchange Offer.
 
     THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF ORIGINAL PREFERRED SHARES IN ANY
JURISDICTION IN WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE
IN COMPLIANCE WITH THE SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.

     The Company owns network components where economically advantageous and
leases components where more capital efficient. The Company has switches in
Quincy, Massachusetts and Orlando, and intends to add switches throughout the
second half of 1998 and continuing through 1999 in Atlanta, Chicago, Los Angeles
and New York City as well as multiple local traffic switches in the Northeastern
and Southeastern regions of the United States. In May 1998, over 60% of the
Company's revenue was generated by customer traffic carried on its network, and
the Company expects this percentage to increase as the Company further expands
its facilities-based infrastructure. The Company recently entered into two
20-year indefeasible right-of-use ("IRU") agreements pursuant to which it
acquired 625 route miles of dark fiber (1,830 digital fiber miles), that, when
fully deployed and activated, will form a redundant fiber ring connecting major
markets throughout New England and the New York metropolitan area and provide
the Company with significant transmission capacity.
 
     The Company believes that, because of its large and highly focused sales
force and superior customer support, the Company will be successful in rapidly
acquiring new customers, cross-selling local services to its existing long
distance customers, continuing to migrate "off-net" long distance customers to
its network, cross-selling enhanced products and services and maintaining a high
rate of customer retention. The Company experienced a compounded annual growth
rate in customers in the three-year period ended December 31, 1997 of 68%.
 
     The Company's business strategy is to leverage its eight-year operating
history, existing customer base and substantial in-region experience to (i) be a
one-stop ICP offering comprehensive bundled voice and data solutions, (ii)
acquire and retain market share through its direct sales force and focused
customer service, (iii) enhance its facilities-based infrastructure where
economically advantageous and continue the migration of traffic to its network,
(iv) build and retain market share through advanced technologies and an advanced
operational support system, (v) target the market of small and medium-sized
businesses, which the Company believes to be underserved, with a focus on the
Northeastern and Southeastern regions of the United States, (vi) increase
international wholesale sales and (vii) expand through strategic acquisitions
and alliances.

NETWORK INFRASTRUCTURE
 
     The Company pursues a capital-efficient network deployment strategy that
involves purchasing switches and acquiring or leasing fiber optic transmission
facilities on an incremental basis to satisfy customer demand. The Company
believes that its switch-based, lease-or-acquire transport strategy provides
significant competitive advantages. By owning network components, the Company is
able to generate higher operating margins and maintain greater control over its
network operations. The Company structures its network expansion decisions in a
manner designed to (i) reduce up-front capital expenditures required to enter
new markets, (ii) avoid the risk of stranded investment in under-utilized fiber
networks and (iii) enter markets and generate revenue and positive cash flow
more rapidly than if the Company first constructed its own facilities. Where
market penetration does not economically justify the deployment of its own
network, the Company utilizes the networks of alternative carriers.
 
     In addition to its 625 route miles of dark fiber, Network Plus currently
owns and maintains (i) a Northern Telecom, Inc. ("Nortel") international gateway
and interexchange switch in Quincy, Massachusetts, and (ii) a Nortel
interexchange switch in Orlando. The Company is currently deploying both a
Nortel international gateway and interexchange switch in Los Angeles and a
Nortel interexchange switch in Chicago. The Company has a Network Operations
Center in Quincy, Massachusetts, which monitors the Company's entire network
from a central location, increasing the security, reliability and efficiency of
the Company's operations. The Company is also planning the deployment of local
switching facilities throughout the Northeastern and Southeastern regions of the
United States. The Company intends to further expand its network in geographic
areas where customer concentrations or traffic patterns make expansion
economically advantageous.
 
SERVICES
 
     Network Plus offers retail telecommunications services primarily to small
and medium-sized businesses. Retail offerings currently include long distance
and toll-free services (both with and without Advanced Intelligent Network
("AIN") features), multiple access options, calling and debit card, paging,
data, and custom management control features. The Company plans to add local
exchange services, Internet services and additional AIN features in the latter
part of 1998 and into 1999. The Company also offers international wholesale
services primarily to interexchange carriers ("IXCs") and international
telecommunications carriers. In May 1998, retail and wholesale offerings
accounted for approximately 78% and 22%, respectively, of the Company's total
revenue.
 
LARGE AND GROWING SALES FORCE
 
     As of July 15, 1998, Network Plus had a 152-member, highly focused sales
force consisting of a 140-person direct retail sales force, a six-person
international wholesale sales force and a six-person agent and reseller sales
force. The Company's sales approach is to build long-term relationships with its
customers, with the intent of becoming the single-source provider of their
telecommunications services. The Company trains its sales force in-house with a
customer-focused program that promotes increased sales through both customer
attraction and customer retention. All members of the sales force are given
incentives through a commission structure under which commissions are paid on an
ongoing basis for as long as a customer continues to purchase services from the
Company. This "lifetime residual" is intended to motivate the sales force to
remain actively involved with customers and participate in the customer
retention and support process. The Company believes that this customer
support-focused commission structure and in-house training are unique in the
industry and provide the Company with a competitive advantage in attracting and
retaining customers. The sales force is currently located in eight offices and,
by year end 1999, the Company expects to open additional sales offices and
expand its sales force to approximately 400 members. The Company expects that it
will continue to utilize a modular sales force structure and that existing
employees with substantial sales experience will manage new sales offices,
ensuring a continuation of the Company's customer-focused culture. The Company's
sales force director,
                                        2

regional sales directors, branch managers and team leaders have an average
employment tenure of over five years with the Company.
 
MANAGEMENT
 
     Robert T. Hale, Jr., the Company's President and Chief Executive Officer
and a Director and co-founder, has more than 10 years of experience in the
telecommunications industry. Robert T. Hale, the Company's Chairman and
co-founder, has more than eight years of experience in the telecommunications
industry, is a Director and former Chairman of the 600-member Telecommunications
Reseller Association (the "TRA") and has been Chairman of the TRA's Underlying
Carrier Committee since 1992. Network Plus's eight-member Executive Officer
group has an average employment tenure of more than three years with the Company
and an average of over 11 years of experience in the telecommunications
industry. The Company believes that the quality, tenure and teamwork of its
management team will be critical factors in the implementation of its expansion
strategy.
 
                               MARKET OPPORTUNITY
 
     As a result of the Telecommunications Act of 1996 (the "Telecommunications
Act") and other federal, state and international initiatives, numerous
telecommunications markets have been opened to competition. In addition, the
increasing globalization of the world economy, along with an increased reliance
on data transmission and Internet access, has expanded the traditional
telecommunications markets. After completing its planned expansion, the Company
expects to have 18 sales offices in 12 states in the Northeastern and
Southeastern regions of the United States. According to industry data, in 1997
there were approximately 8.7 million business lines in the Company's markets in
the Northeastern region (the New England states, New York and New Jersey) and
4.8 million business lines in the Company's markets in the Southeastern region
(Florida, Georgia, North Carolina, South Carolina and Tennessee). The Company
anticipates significant demand for its services, based on its belief that small
and medium-sized businesses are not aggressively targeted by large
telecommunications providers and are underserved with respect to customer
service and support.
 
                               BUSINESS STRATEGY
 
     Network Plus intends to undertake an aggressive growth strategy to meet its
goal of becoming the ICP of choice providing one-stop telecommunications
solutions to customers in its markets. The Company's future success will depend
upon its ability to implement this strategy. Unlike many emerging
telecommunications companies, the Company has a proven eight-year operating
history. The Company believes that the collective talent and telephony
experience of its management and employee base provide a competitive advantage
and position the Company to effectively implement its growth strategy, which
includes the following:
 
PROVIDE INTEGRATED TELECOMMUNICATIONS SERVICES
 
     A key element in the Company's growth will be the implementation of a
marketing and operating plan that emphasizes an integrated voice and data
telecommunications solution. To a large extent, customers the Company expects to
target have not previously had the opportunity to purchase bundled services from
a single provider. The Company believes that these customers will prefer one
source for all of their telecommunications requirements, including products,
billing and service. The Company intends to be the single source of, and provide
a consolidated bill for, integrated local, long distance and other
telecommunications services, in addition to providing a single point of contact
for customer service, product inquiries, repairs and billing questions. The
Company believes that offering one-stop integrated communications services will
enable it to further penetrate its
 
                                        3

- --------------------------------------------------------------------------------
 
existing markets, expand its customer base, capture a larger portion of its
customers' total expenditures on telecommunications services and increase
customer retention.
 
EXPAND SALES FORCE AND FOCUS ON CUSTOMER SERVICE
 
     The Company intends to significantly expand its sales force to both acquire
and support a growing customer base. As of July 15, 1998, the Company's sales
force consisted of 152 members and is expected to grow to approximately 400 by
year end 1999. To support its customer base, the Company provides customer
service 24 hours per day, 365 days per year, and estimates that its customer
service representatives currently have an average response time for answering
incoming calls of under 15 seconds. In addition, the commission structure of the
Company's direct retail sales force is designed to promote a high level of
ongoing customer care and to assure that the sales staff remains actively
involved in the customer service process. Similarly, the compensation of
customer support personnel is designed to promote a high level of ongoing
customer care and retention. The Company believes that its sales and customer
service processes have resulted in a customer retention rate that is higher than
that of many competitors and differentiate the Company as a customer-focused
ICP, giving it a competitive advantage.
 
ENHANCE FACILITIES-BASED INFRASTRUCTURE
 
     The Company intends to continue the migration of customer traffic to its
own network and to cross-sell new services, such as local service, to its
customers. Expansion of the Company's facilities-based infrastructure with both
fiber and switches will increase the proportion of telecommunications traffic
that is originated or terminated on its network, which the Company believes will
result in higher long-term operating margins and greater control over its
operations. The Company's approach to network design is structured to minimize
the capital investment necessary to provide service, avoid spending capital
where not economically justifiable, better match the commitment of capital to
the onset of revenue-generating activities and generate cash flow more quickly.
Throughout the second half of 1998 and continuing through 1999, the Company
intends to enhance its facilities by purchasing and installing (i) Nortel
interexchange switches in Chicago and New York, (ii) a Nortel interexchange and
local switch in Atlanta, (iii) a Nortel interexchange and international gateway
switch in Los Angeles and (iv) multiple Nortel local traffic switches throughout
the Northeastern and Southeastern regions of the United States. In addition, the
Company intends to begin offering high-quality dedicated and dial-up Internet
services.
 
CONTINUE INVESTING IN ADVANCED TECHNOLOGIES AND AN ADVANCED OPERATIONAL SUPPORT
SYSTEM
 
     Network Plus expects to continue to invest in advanced technologies that
provide strategic advantages by integrating the Company's network facilities
with its operational support system ("OSS") to enhance service response time.
The Company intends to deploy Nortel's Service Builder throughout its network
infrastructure, which will elevate the Company's network from a state-of-the-art
SS7 network to a next-generation intelligent network. Service Builder will also
permit the rapid deployment of "designer" intelligent network products and
services such as nationwide "follow me" numbers and Time-of-Day Routing, as well
as accelerate the Company's compliance with legally mandated services such as
local number portability ("LNP"). To support integrated provisioning and
customer care for all products and services, the Company is developing an open
scalable client/server Oracle-based platform that is expected to better
integrate its operations, both geographically and among departments. The Company
believes that these technologies will provide a long-term competitive advantage
by allowing a more rapid implementation of switched local services in its
markets, shortening the time between the receipt of a customer order and the
generation of revenue and enabling a higher level of focused customer care.

TARGET UNDERSERVED MARKETS WITH A SUPER-REGIONAL FOCUS
 
     Network Plus intends to continue targeting small and medium-sized
businesses in the Northeastern and Southeastern regions of the United States,
its primary service areas, while expanding into other markets in the
Mid-Atlantic region, Illinois and California. The Company will seek to be among
the first to market integrated communications services in many of its markets.
The Company believes that the Northeastern and Southeastern regions are
particularly attractive due to a number of factors, including (i) the population
density in the Northeast; (ii) a large number of rapidly growing metropolitan
clusters in the Southeast, such as Atlanta, Miami/Fort Lauderdale and Orlando;
and (iii) the relatively small number of significant competitors to the
incumbent local exchange carriers ("ILECs"). In addition, the Company believes
that small and medium-sized businesses have been underserved by large
competitors with respect to customer service and support, and that its emphasis
on customer service, support and satisfaction provides it with a distinct
competitive advantage. The Company also believes that ILECs, such as regional
Bell operating companies ("RBOCs"), and the largest national carriers primarily
concentrate their sales and marketing efforts on residential and large business
customers and that the market for small and medium-sized businesses is generally
less competitive.
 
INCREASE INTERNATIONAL WHOLESALE SALES
 
     The Company intends to continue targeting the sale of both international
and domestic termination and transport services to wholesale customers such as
large IXCs and international telecommunications carriers. The Company believes
that the international market represents a growing opportunity as a result of
the rapidly increasing globalization of the world economy. The Company's
international department is focused on the development of offshore
telecommunications relationships that provide the Company with lower
international termination costs as well as greater price stability than can be
obtained from U.S.-based carriers. These relationships are being leveraged by
the Company to obtain revenue through the domestic termination of offshore-
originated traffic, in addition to their primary role of enabling the Company to
offer international termination to its customers. The Company has already made
significant investments in its international network capabilities, including a
Nortel international gateway switch in Quincy, Massachusetts and lease and
indefeasible right of use ("IRU") arrangements for international submarine cable
capacity in TAT 12/13 and Americas I in the Atlantic Ocean and TPC-5 in the
Pacific Ocean, as well as various subsidiary feeder cable systems. In addition
to increasing revenue, the Company expects that its strategy of selling
international wholesale services will lower the overall cost of carrying
international traffic and result in more attractive service offerings in its
core retail markets. As of June 1, 1998, the Company provided its international
wholesale services to 13 domestic and foreign telecommunications carriers, and
in May 1998 such services accounted for 22% of the Company's revenue.
 
EXPAND THROUGH STRATEGIC ACQUISITIONS AND ALLIANCES
 
     As part of its expansion strategy, the Company plans to consider
acquisitions, joint ventures and strategic alliances in telecommunications,
Internet access and other related service areas. The Company believes that
acquisitions of, and joint ventures and other strategic alliances with, related
or complementary businesses may enable it to more rapidly expand by adding new
customers, new services, additional customer service and technical support
capabilities, and additional cash flow. The acquisitions could be funded by
cash, bank financing or the issuance of debt or equity securities. The Company
is evaluating and often engages in discussions regarding various acquisition
opportunities, but is not currently a party to any agreement for a material
acquisition.

                              RECENT DEVELOPMENTS
 
FIBER ACQUISITIONS
 
     The Company entered into two 20-year IRU agreements in July 1998 pursuant
to which it acquired 625 route miles of dark fiber (1,830 digital fiber miles).
When the fiber is fully deployed and activated, it will form a redundant fiber
ring connecting major markets throughout New England and the New York
metropolitan area, providing the Company with significant transmission capacity.
The Company anticipates activation of the New York-to-Boston segment in the
second half of 1998 and activation of the full fiber ring in 1999.
 
RECENT HIRES
 
     The Company hired the following employees during the summer of 1998, who
provide the Company with significant expertise in the design, development and
provisioning of local telecommunications services and networks:
 
     Michael F. Oyster has joined Network Plus as President of the Local
Services Division. Mr. Oyster has 22 years of experience in the
telecommunications industry, including local services, long distance services,

(1) EBITDA consists of net income (loss) before interest and other income,
    income taxes, depreciation and amortization. It is a financial performance
    measure commonly used in the telecommunications industry and is presented to
    assist in an understanding of the Company's operating results. However, it
    is not intended to represent cash flows or results of operations in
    accordance with generally accepted accounting principles ("GAAP").
 
(2) For purposes of calculating the ratio of earnings to fixed charges,
    "earnings" represent net income before income taxes plus fixed charges, and
    "fixed charges" consist of interest expense. For the year ended 1997,
    earnings were insufficient to cover fixed charges by $3.1 million.
 
(3) Gives effect to (i) the Initial Offering (after deducting discounts and
    offering expenses payable by the Company, estimated to total $2.5 million)
    and the application of the estimated net cash proceeds therefrom, including
    the repayment of $9.0 million of borrowings under the Existing Bank Credit
    Facility and (ii) the payment of a $5.0 million dividend to the Company's
    stockholders and the reinvestment of $1.9 million by one of the Company's
    stockholders (representing such stockholder's approximate net after-tax
    proceeds of the dividend) in the form of a long-term loan to the Company.
    See "Use of Proceeds" and "Description of Certain
    Indebtedness -- Stockholder Loan".
 
(4) Series A Preferred Stock with an initial liquidation preference of $40.0
    million was issued by the Company as part of the Units offered in the
    Initial Offering. Each Unit consisted of one share of Series A Preferred
    Stock, 7.75 Initial Warrants and 15 Contingent Warrants, each Warrant to
    purchase one share of Common Stock. An assumed initial value of $4.65
    million was allocated to additional paid-in capital, representing the
    portion of the purchase price of the Units allocated to the Initial
    Warrants, less $0.3 million of the costs associated with the Initial
    Offering allocable to the Initial Warrants. No assurance can be given that
    the value allocated to the Initial Warrants will be indicative of the price
    at which the Initial Warrants may actually trade. Costs of $2.2 million
    associated with the Initial Offering have been allocated to the Series A
    Preferred Stock.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, prospective
participants in the Exchange Offer should consider carefully the following risk
factors:
 
NEGATIVE CASH FLOW AND OPERATING LOSSES
 
     The Company had operating losses in each of the years ending December 31,
1997, 1996 and 1995 and negative cash flow in the year ended December 31, 1997,
and there can be no assurance that the Company will achieve or sustain
profitability or generate positive cash flow in the future. The Company expects
to incur significant expenditures in the future in connection with the
acquisition, development and expansion of its network, information technology
systems, employee base, services and customer base.
 
     To the extent the Company's cash needs exceed the Company's available cash
and existing borrowing availability, the funding of these expenditures will be
dependent upon the Company's ability to raise substantial financing. The Company
estimates that, for 1998 and 1999, capital required for expansion of its
infrastructure and services and to fund negative cash flow will be approximately
$140 million. At December 31, 1997, the Company had approximately $1.5 million
in cash and cash equivalents available for such purposes. In addition, the
Company continues to consider potential acquisitions or other arrangements that
may fit the Company's strategic plan. Any such acquisitions or arrangements are
likely to require additional equity or debt financing, which the Company will
seek to obtain as required and may also require that the Company obtain the
consent of its debt holders. The Company may be required to apply all or a
portion of any such financing to redeem all or a portion of the Series A
Preferred Stock. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Business Strategy".
 
SUBSTANTIAL FUTURE CAPITAL REQUIREMENTS; NEED FOR ADDITIONAL FINANCING;
SUBSTANTIAL LEVERAGE
 
     The Company's ability to meet its projected growth is dependent upon its
ability to secure substantial additional financing in the future. The Company
believes that its current cash resources and available cash from the New
Revolving Credit Facility (see "Description of Certain Indebtedness"), together
with the proceeds of the Initial Offering, will be sufficient to fund the
Company's operating losses and planned capital expenditures through at least
August 1999. The New Revolving Credit Facility has a term of 18 months, and the
Company does not expect to have sufficient free cash to repay such facility at
maturity. Accordingly, the Company expects that it will be required to refinance
such facility. To meet its future financing requirements, sources of funding may
include public offerings or private placements of equity or debt securities,
bank loans and additional capital contributions from new or existing
stockholders. The Company may be required to apply all or a portion of any such
financing to redeem all or a portion of the Series A Preferred Stock. 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, on terms acceptable to
the Company, and within the limitations contained in the Company's commercial
lending agreements and the Certificate of Designation. Failure to obtain such
financing could result in the delay or abandonment of the Company's development
and expansion plans and could have a material adverse effect on the Company.
 
     The Company's business plan for the next 12 months is to a large extent
dependent upon the availability of the New Revolving Credit Facility. There can
be no assurance that the Company will enter into the New Revolving Credit
Facility or that it will remain available to the Company through any given
period. In the event the Company does not enter into the New Revolving Credit
Facility, the Company believes that its cash resources will be sufficient to
fund the Company's operating losses and capital expenditures for only the next
three months. In such event, the Company would be unable to implement its growth
strategy in accordance with its projected schedule, if at all. See
"Business -- Growth Strategy". Accordingly, the failure of the Company to
maintain the availability
 
                                       14
<PAGE>   20
 
of such facility for at least the next 12 months would have a material adverse
effect on the business and prospects of the Company.
 
     After giving effect to proposed borrowings under the New Revolving Credit
Facility, the Company will have a significant amount of indebtedness
outstanding. In addition, as a result of its growth strategy, the Company
expects to incur additional indebtedness in the future. The Company's ability to
make cash payments with respect to its outstanding indebtedness and the Series A
Preferred Stock, and to repay its obligations on such indebtedness and preferred
stock at maturity, will depend on its future operating performance, which will
be affected by prevailing economic conditions and financial, business and other
factors, certain of which are beyond the Company's control. On or prior to
September 1, 2003, the Company may pay dividends on the Series A Preferred Stock
by allowing such dividends to be added to the Specified Amount of the Series A
Preferred Stock. It is not anticipated that the Company will pay any dividends
in cash for any period ending on or prior to September 1, 2003. Accordingly, the
Specified Amount of the Series A Preferred Stock and the cash dividend
obligation in respect thereof may increase significantly. If the Company is
unable to service its indebtedness or other obligations, it will be forced to
examine alternative strategies that may include actions such as reducing or
delaying capital expenditures, restructuring or refinancing its indebtedness or
preferred stock, or seeking additional debt or equity financing. There can be no
assurance that any of these strategies could be effected on satisfactory terms,
if at all.
 
     The degree to which the Company is leveraged could have important
consequences to the holders of the Securities, including the following: (i) the
Company will have significant and increasing cash interest expense and
significant principal repayment obligations with respect to outstanding
indebtedness; (ii) the Company's degree of leverage and related debt service
obligations could limit its ability to plan for, and make it more vulnerable
than some of its competitors to the effects of, an economic downturn or other
adverse developments; (iii) any cash flow from the operations of the Company may
need to be dedicated to debt service payments and might not be available for
other purposes; and (iv) the Company's ability to obtain additional financing in
the future for working capital, capital expenditures, debt service requirements
or other purposes could be impaired. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business -- Business
Strategy".
 
HOLDING COMPANY STRUCTURE
 
     The Company is a holding company with no material sources of income or
assets other than the stock of its subsidiary, and the Securities will be
obligations exclusively of the Company. Since all of the Company's operations
are conducted through its subsidiary, the Company's cash flow and its ability to
meet its own obligations, including payment of dividends on the Series A
Preferred Stock, are dependent upon the earnings of its subsidiary and the
distributions of those earnings to the Company, or upon loans or other payments
of funds made by such subsidiary to the Company. The Company's subsidiary is a
separate and distinct legal entity and will have no obligation, contingent or
otherwise, to pay any dividends or make any other distributions to the Company
or to otherwise pay amounts due with respect to the Series A Preferred Stock or
to make funds available for such payments. The Existing Bank Credit Facility
prohibits the payment of dividends by the subsidiary to the Company. Future debt
instruments of the Company's subsidiary likely will impose significant
restrictions that affect, among other things, the ability of the Company's
subsidiary to pay dividends or make loans, advances or other distributions to
the Company. The Certificate of Designation permits the Company's subsidiaries
to enter into agreements containing such restrictions. See "Description of
Certain Indebtedness". The ability of the Company's subsidiary to pay dividends
and make other distributions also will be subject to, among other things,
applicable state laws and regulations.
 
     The Series A Preferred Stock will be structurally subordinated to all
existing and future indebtedness, trade payables, preferred stock and other
obligations of the Company's subsidiary
                                       15
<PAGE>   21
 
(including, without limitation, the Existing Bank Credit Facility). Therefore,
the Company's right and the rights of its creditors, including the holders of
the Series A Preferred Stock, to participate in the assets of the subsidiary
upon the subsidiary's liquidation or reorganization will be subject to the prior
claims of the subsidiary's creditors and holders of preferred stock, if any,
except to the extent that the Company may itself be a creditor with recognized
claims against the subsidiary, in which case the claims of the Company would
still be effectively subordinated to any security interests in or mortgages or
other liens on the assets of such subsidiary and would be subordinate to any
indebtedness of the subsidiary senior to that held by the Company. As of June
30, 1998, on a pro forma basis after giving effect to the Offering, the total
amount of outstanding consolidated liabilities of the Company, including trade
payables, would have been approximately $26.3 million, approximately $4.3
million of which would have been secured obligations, and (ii) the total amount
of outstanding liabilities of the Company's subsidiary, including trade
payables, would have been approximately $26.3 million, approximately $4.3
million of which would have been secured obligations. See "Description of
Certain Indebtedness". The Certificate of Designation limits, but does not
prohibit, the incurrence of additional indebtedness by the Company and its
subsidiary. Therefore, both the Company and its subsidiary will retain the
ability to incur substantial additional indebtedness, and the Company expects
that it and its subsidiary may incur substantial additional indebtedness in the
future.
 
ABILITY TO PAY DIVIDENDS ON THE SERIES A PREFERRED STOCK
 
     The ability of the Company to pay any dividends is subject to applicable
provisions of state law, and its ability to pay cash dividends on the Series A
Preferred Stock will be subject to the terms of the Existing Bank Credit
Facility and any other indebtedness of the Company then outstanding. The ability
of the Company to pay cash dividends is dependent upon the receipt of cash from
its Subsidiary. The payment of cash dividends by the Subsidiary to the Company,
however, is prohibited under the current terms of the Existing Bank Credit
Facility, and there can be no assurance the Existing Bank Credit Facility will
be amended to permit the payment of such dividends. See "Risk Factors -- Holding
Company Structure". The ability of the Company to pay cash dividends is also in
part dependent upon the availability of the New Revolving Credit Facility, and
there can be no assurance that such facility will remain in effect. See "Risk
Factors -- Substantial Future Capital Requirements; Need for Additional
Financing; Substantial Leverage".
 
     Under Delaware law the Company is permitted to pay dividends on its capital
stock, including the Series A Preferred Stock, only out of its surplus, or in
the event that it has no surplus, out of its net profits for the year in which a
dividend is declared or for the immediately preceding year. Surplus is defined
as the excess of a company's total assets over the sum of its total liabilities
plus the par value of its outstanding capital stock. In order to pay dividends
in cash, the Company must have surplus or net profits equal to the full amount
of the cash dividends at the time such dividend is declared. Delaware law
permits the Board of Directors of the Company to revalue the Company's assets
and liabilities from time to time to their fair market value in order to create
surplus. The Company cannot predict what the value of its assets or the amount
of its liabilities will be in the future, nor the amounts of its net profits,
and, accordingly, there can be no assurance that the Company will be able to pay
cash dividends on the Series A Preferred Stock.
 
TAX CONSEQUENCES OF DISTRIBUTIONS WITH RESPECT TO THE SERIES A PREFERRED STOCK
 
     It is anticipated that the redemption price of the Series A Preferred Stock
will exceed its issue price (i.e., the portion of the purchase price of a Unit
sold in the Initial Offering that was initially allocated to the Series A
Preferred Stock). As a result, a holder will be required to treat such excess as
a series of constructive distributions on the Series A Preferred Stock occurring
over the term of such stock. The Company intends to treat the redemption price
as the amount that will be paid upon retirement of the Series A Preferred Stock
on September 1, 2009. As a result, the difference between the issue price of the
Series A Preferred Stock and its redemption price on September 1, 2009, will
constitute constructive distributions on the Series A Preferred Stock to U.S.
Holders over
                                       16
<PAGE>   22
 
the period commencing on the issue date thereof and ending on September 1, 2009.
To the extent of the Company's current and accumulated earnings and profits (as
calculated for Federal income tax purposes), the amount of each consecutive
distribution will be includable in a holder's income as ordinary dividend income
at the time such distribution is deemed to occur, notwithstanding that the cash
attributable to such income will not be received by the holder until a
subsequent period.
 
RANKING OF THE SERIES A PREFERRED STOCK
 
     The Company's obligations with respect to the Series A Preferred Stock are
subordinate and junior in right of payment to all present and future
indebtedness of the Company and its subsidiaries, but will rank senior to
existing equity securities of the Company. In the event of bankruptcy,
liquidation or reorganization of the Company, the assets of the Company will be
available to pay obligations on the Series A Preferred Stock only after all
holders of indebtedness, and all other creditors, of the Company have been paid,
and there may not be sufficient assets remaining to pay amounts due on any or
all of the Series A Preferred Stock then outstanding. See "Description of the
Series A Preferred Stock--Ranking".
 
     While any shares of Series A Preferred Stock are outstanding, the Company
may not authorize, create or increase the authorized amount of any class or
series of stock that ranks senior to or pari passu with the Series A Preferred
Stock with respect to the payment of dividends or amounts upon liquidation,
dissolution or winding up without the consent of the holders of a majority of
the outstanding shares of Series A Preferred Stock. However, without the consent
of any holder of Series A Preferred Stock, the Company may create additional
classes of stock, increase the authorized number of shares of preferred stock or
issue a new series of stock that ranks junior to the Series A Preferred Stock
with respect to the payment of dividends and amounts upon liquidation,
dissolution or winding up.
 
CERTAIN FINANCIAL AND OPERATING RESTRICTIONS
 
     The Certificate of Designation, the Existing Bank Credit Facility and the
New Revolving Credit Facility impose operating and financial restrictions on the
Company and its subsidiaries. These restrictions affect, and in certain cases
significantly limit or prohibit, among other things, the ability of the Company
or any subsidiaries to incur additional indebtedness, issue stock of any
subsidiaries, create liens on its assets, pay dividends or make other
distributions, sell assets, engage in mergers or acquisitions or make
investments. Failure to comply with any of these restrictions could limit the
availability of borrowings or result in a default thereunder. In addition, the
terms of any debt or equity financings undertaken by the Company to meet its
future cash requirements could restrict the Company's operational flexibility
and thereby adversely affect the Company. See "Description of Certain
Indebtedness" and "Description of the Series A Preferred Stock".
 
MANAGEMENT OF RAPID GROWTH
 
     Subject to the sufficiency of its cash resources, the Company intends to
continue to rapidly expand its business. The Company's future performance will
depend, in large part, upon its ability to implement and manage its growth
effectively. The Company's rapid growth has placed, and in the future will
continue to place, a significant strain on its administrative, operational and
financial resources. The Company anticipates that, if successful in expanding
its business, the Company will be required to recruit and hire a substantial
number of new sales and other personnel. Pursuant to the Company's growth
strategy, the Company currently intends to increase the size of its sales force
from 152 as of July 15, 1998 to approximately 400 by the end of 1999. Failure to
retain and attract additional qualified sales and other personnel, including
management personnel who can manage the Company's growth effectively, and
failure to successfully integrate such personnel, could have a material adverse
effect on the Company. To manage its growth successfully, the Company will also
have to continue to improve and upgrade operational, financial, accounting and
information systems, controls and infrastructure as well as expand, train and
manage its employee
 
                                       17
<PAGE>   23
 
base. In the event the Company is unable to upgrade its financial controls and
systems adequately to support its anticipated growth, the Company could be
materially adversely affected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business -- Business
Strategy".
 
LACK OF EXPERIENCE OFFERING LOCAL AND OTHER TELECOMMUNICATIONS SERVICES
 
     The Company's strategy includes offering additional telecommunications
services, including local service and Internet access. The Company has no
experience providing local service and Internet access. To be successful, the
Company must compete successfully with companies that have greater financial
resources and experience than the Company. To provide these additional services,
the Company expects that it will be necessary to make upgrades to its network in
advance of the receipt of any revenue. In addition, the provision of certain of
these services may involve technical requirements with respect to which the
Company has little experience. The provision of these services must also be
successfully integrated into the Company's business. There can be no assurance
that the Company's future services will receive market acceptance in a timely
manner, if at all, or that prices and demand for these services will be
sufficient to provide profitable operations. See "Business -- Business
Strategy", "Business -- Service Offerings -- Planned Services" and "Business --
Network -- Anticipated Network Expansion".
 
ABILITY TO SECURE AND MAINTAIN INTERCONNECTION AND PEERING ARRANGEMENTS
 
     The Company's success will depend upon its ability to develop and expand
its network infrastructure and support services in order to offer local
telecommunication services, Internet access and other services. Executing the
Company's business strategy will require that the Company enter into agreements,
on acceptable terms and conditions, with various providers of infrastructure
capacity, in particular, interconnection agreements with ILECs and peering
agreements with internet service providers ("ISPs"). No assurance can be given
that all of the requisite agreements can be obtained on satisfactory terms and
conditions.
 
     The Company must enter into agreements for the interconnection of the
Company's network with the networks of the ILECs covering each market in which
the Company intends to offer local service. As of September 15, 1998, the
Company had entered into an interconnection agreement with Bell
Atlantic -- Massachusetts, and the Company expects to execute several additional
interconnection agreements in 1998 and early 1999. There can be no assurance
that the Company will successfully negotiate such additional agreements; the
failure to secure and maintain such agreements could have a material adverse
effect on the Company's ability to become a single source provider of
telecommunications services.
 
     Peering agreements between the Company and ISPs will be necessary in order
for the Company to exchange traffic with ISPs without having to pay transit
costs. The basis on which the large national ISPs make peering available or
impose settlement charges is evolving as the provisioning of Internet access and
related services has expanded. Recently, companies that have previously offered
peering have reduced or eliminated peering relationships and are establishing
new, more restrictive criteria for peering. Furthermore, if increasing costs and
other requirements associated with maintaining peering with the major national
ISPs develop, the Company may have to comply with those additional requirements
in order to continue to maintain any peering relationships it negotiates.
Failure to establish and maintain peering relationships would cause the Company
to incur additional operating expenses or abandon certain elements of its
strategy, which could have a material adverse effect on the Company. See
"Government Regulation".
 
DEPENDENCE UPON SUPPLIERS AND OTHER SERVICE PROVIDERS
 
     The Company relies on other companies to supply certain key components of
its network infrastructure, including telecommunications services, network
capacity and switching and network-
 
                                       18
<PAGE>   24
 
ing equipment, which, in the quantities and quality demanded by the Company, are
available only from sole or limited sources. The Company is also dependent upon
ILECs and other carriers to provide telecommunications services and facilities
to the Company and its customers. The Company has from time to time experienced
delays or other problems in receiving telecommunications services and facilities
which it requests, and there can be no assurance that the Company will be able
to obtain such services or facilities on the scale and within the time frames
required by the Company at an affordable cost, or at all. As the Company expands
its service offerings to include local services, it will compete increasingly
with ILECs, which will serve as a disincentive for such entities to cooperate
with the Company. Any failure to obtain such components, services or additional
capacity on a timely basis at an affordable cost, or at all, would have a
material adverse effect on the Company. See "Business -- Competition" and
"Government Regulation".
 
     In May 1998, approximately 40% of the Company's revenue was attributable to
the resale of long distance service provided by Sprint Communications Company
L.P. ("Sprint"). The current agreement with Sprint, which became effective as of
February 1998, terminates in February 2000, and there can be no assurance that
this agreement will be extended on terms acceptable to the Company, if at all.
Early termination of the Company's relationship with Sprint could have a
material adverse effect on the Company. See "Business -- Network -- Sprint
Agreement".
 
     The accurate and prompt billing of the Company's customers is dependent
upon the timeliness and accuracy of call detail records ("CDRs") provided by any
carrier whose service the Company resells. There can be no assurance that the
current carriers will continue to provide, or that new carriers, including
ILECs, will provide, accurate information on a timely basis, and any such
carrier's failure to do so could have a material adverse effect on the Company.
 
RELIANCE ON LEASED TRANSPORT FACILITIES AND IRUs
 
     Because the Company leases a portion of its transport capacity, it is
dependent upon the availability of fiber optic transmission facilities owned by
ILECs, competitive local exchange carriers ("CLECs") and other fiber optic
transport providers who lease their fiber optic networks to service providers
such as the Company. Many of these entities are, or may become, competitors of
the Company. See "-- Competition". The Company recently entered into two 20-year
IRU agreements pursuant to which it acquired dark fiber mileage, and may enter
into additional IRU agreements in the future. Integration of fiber mileage
acquired pursuant to IRU agreements into the Company's network will subject the
Company to the risk that the owners of the underlying facilities, who may be
competitors of the Company, will not maintain, or will deny the Company access
to, such facilities. The risks inherent in this approach include, but are not
limited to, the possible inability to negotiate and renew favorable supply
agreements, and dependence on the timeliness of the ILECs, CLECs or other fiber
optic transport providers in processing the Company's orders for customers who
seek to utilize the Company's services. See "Business -- Network".
 
DEPENDENCE ON RIGHTS-OF-WAY AND OTHER THIRD PARTY AGREEMENTS
 
     To further develop its network, the Company may need to obtain local
franchises and other permits, as well as rights to utilize underground conduit
and aerial pole space and other rights-of-way and fiber capacity from entities
such as ILECs and other utilities, railroads, long distance companies, state
highway authorities, local governments and transit authorities. There can be no
assurance that the Company will be able to obtain and maintain such franchises,
permits and rights needed to implement its business strategy on acceptable
terms. Although the Company does not believe that any such arrangements would be
canceled or would not be renewed as needed, cancellation or non-renewal of such
arrangements could materially adversely affect the Company's business in the
affected area. See "Business -- Network -- Anticipated Network Expansion" and
"Government Regulation".
 
                                       19

COMPETITION
 
     The Company operates in a highly competitive environment and currently does
not have a significant market share in any of its markets. Most of its actual
and potential competitors have substantially greater financial, technical,
marketing and other resources (including brand or corporate name recognition)
than the Company. Also, the continuing trend toward business alliances in the
telecommunications industry and the absence of substantial barriers to entry in
the data and Internet services markets could give rise to significant new
competition.
 
     The long distance telecommunications industry is highly competitive and
affected by the introduction of new services by, and the market activities of,
major industry participants. The Company competes against various national and
regional long distance carriers, including both facilities-based providers and
switchless resellers offering essentially the same services as the Company. In
addition, significant competition is expected to be provided by ILECs. The
Company's success will depend upon its ability to provide high-quality services
at prices competitive with those charged by its competitors. In addition, the
long distance industry is characterized by a high level of customer attrition or
"churn". Such attrition is attributable to a variety of factors, including
initiatives of competitors as they engage in advertising campaigns, marketing
programs and cash payments and other incentives. End users often are not
obligated to purchase any minimum usage amount and can discontinue service
without penalty at any time. The Company's revenue has been, and is expected to
continue to be, affected by churn.
 
     AT&T Corp. ("AT&T"), MCI WorldCom, Inc. ("MCI"), Sprint and other carriers
have implemented new price plans aimed at residential customers with
significantly simplified rate structures, which may have the impact of lowering
overall long distance prices. There can be no assurance that long distance
carriers will not make similar offerings available to the small to medium-sized
businesses that the Company primarily serves. While the Company believes small
and medium-sized business customers are not aggressively targeted by large long
distance providers such as AT&T, MCI and Sprint, there can be no assurance the
Company's customers and potential customers will not be targeted by these or
other providers in the future. Additional pricing pressure may come from
Internet telephony, which is a developing technology that can transmit voice
communications at a cost that may be below that of traditional circuit-switched
long distance service. While Internet telephony is not yet available in all
areas, currently requires the dialing of additional digits and currently
produces sound quality inferior to that of traditional long distance service, it
could eventually become a substitute for traditional long distance service and
put pricing pressure on long distance rates. Any reduction in long distance
prices may have a material adverse effect on the Company's results of
operations.
 
     In the local telecommunications market, the Company's primary competitor
initially is expected to be the ILEC serving each geographic area. ILECs are
established providers of dedicated and local telephone services to all or
virtually all telephone subscribers within their respective service areas. ILECs
also have long-standing relationships with regulatory authorities at the federal
and state levels. While recent Federal Communications Commission ("FCC")
administrative decisions and initiatives provide increased business
opportunities to voice, data and ISPs, they also provide the ILECs with
increased pricing flexibility for their private line, special access and
switched access services. In addition, with respect to competitive access
services, the FCC recently proposed a rule that would provide for increased ILEC
pricing flexibility and deregulation for such access services either
automatically or after certain competitive levels are reached. If the ILECs are
allowed additional flexibility by regulators to offer discounts to large
customers through contract tariffs, decide to engage in aggressive volume and
term discount pricing practices for their customers, or seek to charge
competitors excessive fees for interconnection to their networks, the revenue of
competitors to the ILECs, including the Company, could be materially adversely
affected. If future regulatory decisions afford the ILECs increased access
services pricing flexibility or other regulatory relief, such decisions could
also have a material adverse effect on competitors to the ILECs.
 
                                       20
<PAGE>   26
 
     The Company will also face competition or prospective competition in local
markets from other carriers, many of which have significantly greater financial
resources than the Company. For example, AT&T, MCI and Sprint have each begun to
offer local telecommunications services in major U.S. markets using their own
facilities or by resale of the ILECs' or other providers' services. In addition
to these long distance service providers, entities that currently offer or are
potentially capable of offering local switched services include companies that
have previously operated as competitive access providers, cable television
companies, electric utilities, microwave carriers, wireless telephone system
operators and large customers who build private networks. These entities, upon
entering into appropriate interconnection agreements or resale agreements with
ILECs, including RBOCs, could offer single-source local and long distance
services, similar to those offered or proposed to be offered by the Company.
 
     In addition, a continuing trend towards business combinations and alliances
in the telecommunications industry may create significant new competitors to the
Company. The proposed acquisition of GTE Corp. by Bell Atlantic Corp., the
proposed merger of SBC Communications, Inc. ("SBC") and Ameritech Corp.
("Ameritech"), the merger of MCI and WorldCom, Inc. ("WorldCom"), AT&T's
proposed acquisition of Telecommunications Inc. and its acquisition of Teleport
Communications Group, Inc., TeleGlobe Inc.'s proposed acquisition of Excel
Communications, and SBC's proposed acquisition of Southern New England
Telephone, Inc. ("SNET"), are examples of some of the alliances that are being
formed. Many of these combined entities will have resources far greater than
those of the Company. These combined entities may provide a bundled package of
telecommunications products, including local and long distance telephony, that
is in direct competition with the products offered or proposed to be offered by
the Company, and may be capable of offering these products sooner and at more
competitive rates than the Company.
 
     The Company will also face competition from fixed wireless services,
including Multichannel Multipoint Distribution Service ("MMDS"), Local
Multipoint Distribution Service ("LMDS"), 24 GHz and 38 GHz wireless
communications systems, FCC Part 15 unlicensed wireless radio devices, and other
services that use existing point-to-point wireless channels on other
frequencies. In addition, the FCC has allocated a number of spectrum blocks for
use by wireless devices that do not require site or network licensing. A number
of vendors have developed such devices that may provide competition to the
Company, particularly for certain low data-rate transmission services.
 
     The FCC has authorized cellular, personal communications service ("PCS"),
and other commercial mobile radio service ("CMRS") providers to offer wireless
services to fixed locations, rather than just to mobile customers, without
limitation. Previously, cellular, PCS and CMRS providers could provide service
to fixed locations only on an ancillary or incidental basis. The authority to
provide fixed as well as mobile services will enable CMRS providers to offer
wireless local loop service and other services to fixed locations (e.g., office
and apartment buildings) in direct competition with the Company and existing
providers of traditional wireless telephone service.
 
     Section 271 of the Telecommunications Act prohibits any RBOC from providing
long distance service that originates (or, in certain cases, terminates) in one
of its in-region states until the RBOC has satisfied certain statutory
conditions in that state and has received the approval of the FCC. The FCC has
denied the following applications for such approval: SBC's Texas application in
June 1998; SBC's Oklahoma application in June 1997; Ameritech's Michigan
application in August 1997; and BellSouth Corporation's applications for South
Carolina and Louisiana in December 1997 and February 1998, respectively. The
Company anticipates that a number of RBOCs will file additional applications for
in-region long distance authority in 1998. Bell Atlantic recently received
conditional approval from the New York Public Service Commission of its Section
271 application for New York State. Thus, it is expected that Bell Atlantic will
file its Section 271 application with the FCC in the near future. The FCC has 90
days from the date an application for in-region long distance authority is filed
to decide whether to grant or deny the application.
 
                                       21
<PAGE>   27
 
     Once the RBOCs are allowed to offer widespread in-region long distance
services, both they and the largest IXCs will be in a position to offer
single-source local and long distance. On December 31, 1997, a United States
District Court judge in Texas held unconstitutional certain sections of the
Telecommunications Act, including Section 271. Section 271 sets forth a
"competitive checklist" that an RBOC must satisfy prior to obtaining authority
to provide in-region interLATA services. This decision would permit the three
RBOCs involved in the suit immediately to begin offering widespread in-region
long distance services. The decision, however, was stayed on February 11, 1998
by the District Court pending the outcome of an appeal on the merits to the U.S.
Court of Appeals for the Fifth Circuit. On September 4, 1998, the Fifth Circuit
reversed the District Court's ruling. Among other things, the Fifth Circuit
found sec.sec.271-75 of the Telecommunication Act to be non-punitive in
character and, therefore, not a bill of attainder as that term has been defined
by the Supreme Court.
 
     In addition, new FCC rules went into effect in February 1998 that make it
substantially easier for many non-U.S. telecommunications companies to enter the
U.S. market, thus potentially further increasing the number of competitors.
 
     The market for data communications and Internet access services is also
extremely competitive. There are no substantial barriers to entry, and the
Company expects that competition will intensify in the future. See
"Business -- Competition", "Business -- Industry Overview" and "Government
Regulation".
 
THE TELECOMMUNICATIONS ACT AND OTHER REGULATION
 
     Telecommunications services are subject to significant regulations at the
federal, state, local and international levels, affecting the Company and its
existing and potential competitors. Delays in receiving required regulatory
approvals or the enactment of new and adverse legislation, regulations or
regulatory requirements may have a material adverse effect on the Company's
financial condition, results of operations and cash flow. In addition, future
legislative, judicial and regulatory agency actions could alter competitive
conditions in the markets in which the Company is operating or intends to
operate, in ways that are materially adverse to the Company.
 
     The Company is currently subject to federal and state government regulation
of its telecommunications services. The Company is regulated at the federal
level by the FCC. It is required to obtain and maintain an FCC 214 license in
connection with its international services, and to file and maintain both
domestic and international tariffs containing the currently effective rates,
terms and conditions of service for its long distance services. The FCC has
issued regulations eliminating the domestic tariffing requirement for all
interstate nondominant carriers, except for, under certain circumstances, RBOCs.
Those regulations have been stayed on appeal by third parties, and the Company
is currently required to file tariffs with the FCC. The FCC generally retains
the right to sanction a carrier or revoke its authorization if a carrier
violates applicable laws or regulations.
 
     The Company's long distance telecommunications operations and proposed
local service operations are also subject to various state laws and regulations.
The Company must obtain and maintain certificates of public convenience and
necessity from regulatory authorities in most states in which it offers
intrastate service. In most states, the Company must also file and obtain prior
regulatory approval of tariffs for intrastate services. The Company must update
or amend its tariffs when rates are adjusted or new products are added to
services offered by the Company. Challenges by third parties to the Company's
federal or state tariffs and complaints about the Company's practices could
cause the Company to incur substantial legal and administrative expenses.
 
     The FCC and numerous state agencies also impose prior approval requirements
on transfers of control, including pro forma transfers of control and corporate
reorganizations, and assignments of regulatory authorizations. The Company did
not obtain prior approval for its July 1998 corporate reorganization to create a
holding company structure whereby Network Plus Corp. became the holding company
of Network Plus, Inc. The Company is in the process of filing the necessary
papers
                                       22
<PAGE>   28
 
at the FCC and relevant state commissions seeking nunc pro tunc (retroactive)
approval of the transaction on the grounds that the transaction serves certain
important business needs of the Company and enhances the Company's ability to
market and provide services more efficiently. Although the Company believes that
its applications will be approved in due course, there can be no assurance that
the FCC or state commissions will grant the Company's requests for retroactive
approval and/or will not impose fines or license conditions, commence revocation
proceedings or otherwise exercise their authority to address violations of
applicable statutes and regulations.
 
     The Telecommunications Act has already resulted in comprehensive changes in
the regulatory environment for the telecommunications industry as a whole, and
will have a material impact on the local exchange industry and the competitive
environment in which the Company operates. The concept of competitive
provisioning of local exchange services is a relatively new development in the
telecommunications industry, and the Company cannot predict how the relevant
provisions of the Telecommunications Act will be interpreted and implemented by
the FCC, state regulators, courts and the ILECs. See "Business -- Competition",
"Business-- Industry Overview" and "Government Regulation".
 
     The Company's cost of providing long distance service, and its revenue from
providing local services, will both be affected by changes in "access charges"
and universal service. In 1997, the FCC released an order establishing a
significantly expanded federal universal service subsidy regime to be funded by
interstate carriers and certain other entities. The FCC established new
universal service funds to support telecommunications and information services
provided to qualifying schools, libraries and rural health care providers, and
expanded the federal subsidies for local telephone services provided to low
income consumers. If the federal and state regulations requiring the local
exchange carriers to provide equal access for the origination and termination of
calls by long distance subscribers change or if the regulations governing access
charge rates or universal service contribution change, such changes could have a
material adverse effect on the Company's financial condition, results of
operations and cash flow. On July 18, 1997, the United States Court of Appeals
for the Eighth Circuit overturned many of the rules the FCC had established
pursuant to the Telecommunications Act. The Eighth Circuit decision
substantially limits the FCC's jurisdiction and expands state regulators'
jurisdiction to set and enforce rules governing the development of local
competition. As a result, it is more likely that the rules governing local
competition will vary substantially from state to state. If a patchwork of state
regulations were to develop, it could increase the Company's cost of regulatory
compliance and could make entry into and conduct of business in some markets
more expensive than in others. The U.S. Supreme Court has decided to review the
Eighth Circuit's decision. There can be no assurance as to how or when the U.S.
Supreme Court will act on the appeal or that the outcome of the appeal will not
have a material adverse effect on the Company's financial condition, results of
operation and cash flow.
 
DEPENDENCE ON BILLING, CUSTOMER SERVICE AND INFORMATION SYSTEMS
 
     Integrated management information and processing systems are vital to the
Company's growth and its ability to monitor costs, bill customers, provision
customer orders and achieve operating efficiencies. As the Company continues its
transition to the provisioning of integrated communications services, the need
for sophisticated billing and information systems will increase significantly.
The cost of implementing such systems has been, and is expected to continue to
be, substantial. Also, the Company's plans for the development and
implementation of its internal systems rely on the delivery of products and
services by third party vendors. Failure of these vendors to deliver the
required information in a timely and effective manner and at acceptable costs,
failure of the Company to adequately identify and integrate all of its
information and processing needs, failure of the Company's related processing or
information systems, or the failure of the Company to upgrade systems as
necessary could have a material adverse effect on the Company.
 
     The Company is dependent upon the prompt collection of payment of its
customers' bills and, in turn, upon the creditworthiness of its customers and
the continued implementation of adequate
                                       23
<PAGE>   29
 
revenue assurance programs. The failure of its customers to pay their bills in a
timely manner or the Company's failure to accurately assess the creditworthiness
of its customers and implement adequate revenue assurance programs could have a
material adverse effect on the Company. In 1997, the Company's provision for
doubtful accounts increased by $3.0 million, principally relating to two
customers and an increase in the estimate of bad debt reserve consistent with
the growth in revenue. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Management Information
Systems, Provisioning, Billing and Collections".
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company believes that its success will depend to a significant extent
upon the abilities and continued efforts of its management, particularly Robert
T. Hale, Jr., the Company's Chief Executive Officer and President, Robert T.
Hale, the Company's Chairman of the Board, and other members of its senior
management team. None of the Company's executive officers is subject to an
employment agreement with the Company providing for the officer's continuing
employment. The loss of the services of any of such individuals could have a
material adverse effect on the Company. The success of the Company will also
depend, in part, upon the Company's ability to hire and retain additional key
personnel, including senior management, technical and sales personnel, who are
also being sought by other businesses. Competition for qualified personnel in
the telecommunications industry is intense. Difficulty in hiring and retaining
such personnel could have a material adverse effect on the Company. See
"-- Management of Rapid Growth", "Business -- Employees" and "Management".
 
IMPACT OF TECHNOLOGICAL CHANGE
 
     The telecommunications industry has been, and is likely to continue to be,
characterized by rapid technological change, frequent new service introductions
and evolving industry standards. Increases or changes in technological
capabilities or efficiencies could create an incentive for more competitors to
enter the facilities-based local exchange business in which the Company intends
to compete. Similarly, such changes could result in lower retail rates for
telecommunications services, which could have a material adverse effect on the
Company's ability to price its services competitively or profitably. Future
technological changes, including changes related to emerging wireline and
wireless transmission and switching technologies and Internet-related services
and technologies, also could have a material adverse effect on the Company.
 
     The Company relies and will continue to rely in part on third parties
(including certain of its competitors and potential competitors) for the
development of and access to communications and networking technology. The
effect of technological changes on the business of the Company cannot be
predicted with any degree of certainty. The Company believes its future success
will depend, in part, on its ability to anticipate or adapt to such changes and
to offer, on a timely basis, services that meet customer demands and evolving
industry standards. There can be no assurance that the Company will obtain
access to new technology on a timely basis or on satisfactory terms, or that the
Company will be able to adapt to such technological changes, offer such services
on a timely basis or establish or maintain a competitive position. Any
technological change, obsolescence or failure to obtain access to important
technologies could have a material adverse effect on the Company. See
"Business -- Industry Overview".
 
YEAR 2000 COMPLIANCE
 
     Many computer systems experience problems handling dates beyond the year
1999. Therefore, some computer hardware and software will need to be modified
prior to the year 2000 in order to remain functional. While the Company believes
that the majority of its software applications will be year 2000 compliant by
the end of 1998, there can be no assurance that all systems will function
adequately beginning in the year 2000. There can also be no assurance the
Company will not incur
 
                                       24
<PAGE>   30
 
significant unanticipated costs in achieving year 2000 compliance. Furthermore,
if the hardware or software comprising the Company's network elements acquired
from third party vendors, the software applications of the long distance
carriers, LECs, or others on whose services the Company depends or with whom the
Company's systems interface, or the software applications of other suppliers,
are not year 2000 compliant, it could affect the Company's systems, which could
have a material adverse effect on the Company. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Impact of Year
2000".
 
STRATEGIC INVESTMENTS; BUSINESS COMBINATIONS
 
     In furtherance of its growth strategy, the Company may pursue acquisitions
of, or joint ventures or strategic alliances with, companies engaged in
businesses similar or related to the business of the Company. As consideration
for such acquisitions, the Company may be required to assume liabilities, incur
additional indebtedness or issue equity securities. There can be no assurance
that the Company will be able to obtain such financing. Such acquisitions,
combinations or alliances, if consummated, could increase the Company's
indebtedness and could divert the resources and management of the Company and
would require integration with the Company's existing networks and services.
There can be no assurance that any acquisitions, combinations or alliances will
occur or, if consummated, would be on terms favorable to the Company or would be
successfully integrated into the Company's operations. See "Business -- Business
Strategy -- Expand Through Strategic Acquisitions and Alliances".
 
DEPENDENCE UPON NETWORK INFRASTRUCTURE; RISK OF SYSTEM FAILURE; SECURITY RISKS
 
     The Company's success in attracting and retaining customers requires that
the Company provide adequate reliability, capacity and security in its network
infrastructure. The Company's networks and the networks upon which it depends
are subject to physical damage, power loss, capacity limitations, software
defects, breaches of security (by computer virus, break-ins or otherwise) and
other factors, certain of which may cause interruptions in service or reduced
capacity for the Company's customers. Interruptions in service, capacity
limitations or security breaches could have a material adverse effect on the
Company. See "Business -- Network".
 
CONTROL BY EXISTING STOCKHOLDERS; DEADLOCK; ANTITAKEOVER PROVISIONS
 
     All of the outstanding Common Stock is owned or voted by Robert T. Hale and
Robert T. Hale, Jr., each an Officer and Director of the Company. Consequently,
management will have complete control over all of the Company's affairs and will
have the ability to control the election of all members of the Company's Board
of Directors and the outcome of all corporate actions requiring stockholder
approval.
 
     Because the outstanding Common Stock is owned equally by the Company's two
stockholders, the failure of such stockholders to agree on a matter that
requires the approval of the holders of a majority of the outstanding shares of
Common Stock would result in a deadlock, which could have the effect of
preventing or delaying the Company from taking any action on the matter. Such a
deadlock could have a material adverse effect on the Company. See "Management"
and "Stock Ownership".
 
     Robert T. Hale and Robert T. Hale, Jr. will have the authority to amend the
Company's Certificate of Incorporation and By-Laws to include certain provisions
that may have the effect of discouraging, delaying or making more difficult a
change in control of the Company or preventing the removal of incumbent
directors even if holders of the Warrants or other securities of the Company
were to deem such action to be in the best interests of the Company. Among other
things, the Certificate of Incorporation may be amended to provide for a
classified Board of Directors. In addition, the Certificate of Incorporation
allows the Board of Directors to issue shares of preferred stock and fix the
rights, privileges and preferences of those shares without any further vote or
action
 
                                       25
<PAGE>   31
 
by the stockholders. The rights of the holders of Common Stock will 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. Any such issuance of shares of preferred
stock could have the effect of making it more difficult for a third party to
acquire a majority of the outstanding voting stock of the Company. In addition,
the Certificate of Incorporation and By-Laws could be amended to, among other
things, limit the manner in which directors may be nominated by the stockholders
and limit the manner in which proposals may be made at stockholder meetings. The
Company may also elect to be subject to Section 203 of the Delaware General
Corporation Law, which could have the effect of delaying or preventing a change
of control of the Company. To the extent that these provisions discourage
takeover attempts, they could deprive stockholders of opportunities to realize
takeover premiums for their shares or could depress the market price of the
Company's securities.
 
FUNDING OF REPURCHASE OBLIGATIONS; ABSENCE OF SINKING FUND; REDEMPTION OF SERIES
A PREFERRED STOCK UPON MATURITY
 
     There is no sinking fund with respect to the Series A Preferred Stock, and
in September 2009 all outstanding shares thereof will become subject to
mandatory redemption by the Company. Also, upon the occurrence of certain
earlier events, including a change in control of the Company, the Company will
be required to offer to repurchase all or a portion of the outstanding Series A
Preferred Stock. The source of funds for any such payment at maturity or earlier
repurchase is expected to be the Company's available cash or cash generated from
operating or other sources, including, without limitation, borrowings or sales
of assets or equity securities of the Company. There can be no assurance that
sufficient funds will be available at the time of any such event to make such
purchase or to make any other required payment. See "Description of the Series A
Preferred Stock". In addition, limitations imposed by other debt obligations of
the Company may limit the Company's ability to repurchase the Series A Preferred
Stock.
 
ABSENCE OF PUBLIC MARKET
 
     The New Preferred Shares are a new issue of securities for which there is
currently no established market. There can be no assurance as to (i) the
liquidity of any market that may develop, (ii) the ability of the holders of New
Preferred Shares to sell any of their New Preferred Shares, or (iii) the price
at which the holders of New Preferred Shares would be able to sell such shares.
The Company does not presently intend to apply for listing of the New Preferred
Shares on any national securities exchange or on The Nasdaq Stock Market. The
Purchasers have advised the Company that they presently intend to make a market
in the New Preferred Shares. The Purchasers are not obligated, however, to make
a market in such shares, and any such market-making may be discontinued at any
time at the sole discretion of the Purchasers and without notice. Accordingly,
no assurance can be given as to the development or liquidity of any market for
the New Preferred Shares. If a market for the New Preferred Shares were to
develop, such shares could trade at prices that may be higher or lower than
their initial offering price depending on many factors, including prevailing
interest rates, the Company's operating results and prospects for its
performance, the market for similar securities and general economic conditions.
Historically, the market for securities such as the New Preferred Shares has
been subject to disruptions that have caused substantial volatility in the
prices of similar securities. There can be no assurance that, if a market for
any of the New Preferred Shares were to develop, such a market would not be
subject to similar disruptions.
 
FAILURE TO EXCHANGE
 
     Holders of Original Preferred Shares who do not exchange their Original
Preferred Shares for New Preferred Shares pursuant to the Exchange Offer will
continue to be subject to the restrictions on transfer of such Original
Preferred Shares set forth in the legend thereon as a consequence of the
issuance of the Original Preferred Shares pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities Act
and applicable state securities laws. In general, the Original Preferred Shares
may not be offered or sold, unless registered under the
 
                                       26
<PAGE>   32
 
Securities Act and applicable state securities laws, or pursuant to an exemption
therefrom. Except under certain limited circumstances, the Company does not
intend to register the Original Preferred Shares under the Securities Act. In
addition, any holder of Original Preferred Shares who tenders in the Exchange
Offer for the purpose of participating in a distribution of the New Preferred
Shares may be deemed to have received restricted securities and, if so, will be
required to comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any resale transaction. To the extent
Original Preferred Shares are tendered and accepted in the Exchange Offer, the
trading market, if any, for the Original Preferred Shares not tendered could be
adversely affected. See "The Exchange Offer".
 
                                       27
<PAGE>   33
 
                                USE OF PROCEEDS
 
     The Company will not receive any proceeds from the issuance of New
Preferred Shares in the Exchange Offer. The net proceeds to the Company of the
Initial Offering were approximately $37.5 million. The Company has used $9.8
million of the net proceeds of the Initial Offering to pay down borrowings
outstanding under the Existing Bank Credit Facility; the Company intends to use
the remainder of the net proceeds to finance its anticipated expansion,
including the expansion of its local telecommunications infrastructure,
information technology systems and sales force.
 
     Pending application of the net proceeds of the Initial Offering as
described herein, the Company intends to use a portion of such proceeds to
temporarily repay revolving indebtedness and to invest the remainder of such
proceeds in short-term, interest-bearing, U.S. government securities and other
short-term, investment grade securities.
 
     Because of the number and variability of factors that may determine the
Company's use of the net proceeds of the Initial Offering, management will
retain a significant amount of discretion over the application of the net
proceeds. There can be no assurance that such applications will not vary
substantially from the Company's current plans. See "Risk Factors -- Control by
Existing Stockholders; Deadlock; Antitakeover Provisions", "Risk
Factors -- Negative Cash Flow and Operating Losses" and "Risk
Factors -- Substantial Future Capital Requirements; Need for Additional
Financing; Substantial Leverage".
 
                                DIVIDEND POLICY
 
     On September 2, 1998, the Company paid a dividend to Robert T. Hale and
Robert T. Hale, Jr. in the aggregate amount of $5.0 million, of which $1.9
million was reinvested by one of the stockholders in the form of a long-term
loan to the Company. For the foreseeable future the Company intends to retain
its earnings for its operations and expansion of its business and it does not
expect to pay dividends on its Common Stock (other than in amounts necessary to
enable the Company's stockholders to pay taxes and related tax preparation
expenses in respect of income allocated to such stockholders through the date
the Company's status as an S corporation ceased). The payment of any future
dividends will be at the discretion of the Board of Directors, except as
required by the terms of the Series A Preferred Stock, and will depend upon,
among other factors, the Company's earnings, financial condition, capital
requirements and general business outlook at the time payment is considered. In
addition, the Company's ability to pay dividends will depend upon the amount of
distributions, if any, received from NPI or any future operating subsidiaries of
the Company. The Company intends to exercise its option to make dividend
payments on the Series A Preferred Stock prior to September 1, 2003 by allowing
such dividends to be added to the Specified Amount of the Series A Preferred
Stock. The Existing Bank Credit Facility will, and any future indebtedness
incurred by the Company, including the New Revolving Credit Facility, may,
restrict the ability of the Company to pay dividends. See "Description of
Certain Indebtedness", "Description of the Series A Preferred Stock" and
"Description of Capital Stock".

                                 CAPITALIZATION
 
     The following table sets forth the total cash and cash equivalents,
marketable securities and investments and capitalization of the Company as of
June 30, 1998, and June 30, 1998, as adjusted to give effect to (i) the Initial
Offering (after deducting discounts and estimated offering expenses payable by
the Company, estimated to total $2.5 million) and the application of the
estimated net cash proceeds therefrom, including the repayment of $9.0 million
of borrowings under the Existing Bank Credit Facility, (ii) this Exchange Offer,
and (iii) the payment of a $5.0 million dividend to the Company's stockholders
and the reinvestment of $1.9 million by one of the Company's stockholders
(representing such stockholder's approximate net after-tax proceeds of the
dividend) in the form of a long-term loan to the Company. This table should be
read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and the historical financial statements,
including the notes thereto, of the Company appearing elsewhere in this
Prospectus. See "Use of Proceeds", "Description of Capital Stock" and

(1) After repayment of $9.0 million of outstanding indebtedness, the Company has
    approximately $15.0 million of availability under the Existing Bank Credit
    Facility. If the New Revolving Credit Facility had been in place on June 30,
    1998, $45 million of the $60 million in total borrowings contemplated by
    such facility would have been available.
 
(2) Series A Preferred Stock with an initial liquidation preference of $40
    million was issued by the Company as part of the Units sold in the Initial
    Offering. Each Unit consisted of one share of Series A Preferred Stock, 7.75
    Initial Warrants and 15 Contingent Warrants, each Warrant to purchase one
    share of Common Stock. An assumed initial value of $4.65 million was
    allocated to additional paid-in capital, representing the portion of the
    purchase price of the Units allocated to the Initial Warrants, less $0.3
    million of the costs associated with the Initial Offering, allocable to the
    Initial Warrants. No assurance can be given that the value allocated to the
    Initial Warrants will be indicative of the price at which the Initial
    Warrants may actually trade. Costs of $2.2 million associated with the
    Initial Offering have been allocated to the Series A Preferred Stock.
 
(3) Represents the portion of the purchase price of the Units allocated to the
    Initial Warrants (as described in note 2 above), less $0.3 million of the
    cost associated with the Initial Offering allocable to the Initial Warrants.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
     The Original Preferred Shares were issued and sold on September 3, 1998 in
a transaction exempt from registration under the Securities Act. Accordingly,
the Original Preferred Shares may not be reoffered, resold or otherwise pledged,
hypothecated or transferred in the United States unless so registered or unless
an applicable exemption from the registration requirements of the Securities Act
is available. The Company has agreed pursuant to the Registration Agreement to
(i) file, within 90 days after the closing of the Initial Offering (the
"Original Preferred Shares Closing Date"), a registration statement with the
Commission with respect to the Exchange Offer, (ii) use its best efforts to
cause such registration statement to be declared effective under the Securities
Act not later than 150 days after the Original Preferred Shares Closing Date and
(iii) upon effectiveness of such registration statement, offer New Preferred
Shares in exchange for surrender of Original Preferred Shares. The New Preferred
Shares are being offered hereunder to satisfy these obligations of the Company
under the Registration Agreement.
 
TERMS OF THE EXCHANGE
 
     The Company is offering, upon the terms and subject to the conditions of
the Exchange Offer, to exchange one New Preferred Share for each outstanding
Original Preferred Share. The terms of the New Preferred Shares are
substantially identical in all respects to the terms of the Original Preferred
Shares for which they may be exchanged pursuant to the Exchange Offer, except
that (i) the offer of the New Preferred Shares will have been registered under
the Securities Act and, therefore, the New Preferred Shares will be freely
transferable by holders thereof (except as otherwise described herein) and not
bear a legend regarding restrictions on transfer, (ii) holders of the New
Preferred Shares will not be entitled to certain rights of the holders of the
Original Preferred Shares under the Registration Agreement, which rights with
respect to the Original Preferred Shares will terminate on consummation of the
Exchange Offer, and (iii) the New Preferred Shares will not contain any
provisions regarding the payment of Special Dividends. See "Description of the
Series A Preferred Stock".
 
     The Exchange Offer is not conditioned upon any minimum number of Original
Preferred Shares being tendered for exchange.
 
     Based on interpretations by the Staff set forth in no-action letters issued
to third parties, the Company believes that New Preferred Shares issued pursuant
to the Exchange Offer in exchange for the Original Preferred Shares may be
offered for resale, resold and otherwise transferred by holders thereof (other
than any holder which is (i) an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act, (ii) a broker-dealer who acquired Original
Preferred Shares directly from the Issuer or (iii) broker-dealers who acquired
Original Preferred Shares as a result of market making or other trading
activities) without compliance with the registration and prospectus delivery
provisions of the Securities Act; provided that such New Preferred Shares are
acquired in the ordinary course of such holders' business, and such holders are
not engaged in, and do not intend to engage in, and have no arrangement or
understanding with any person to participate in, a distribution of such New
Preferred Shares. Each broker-dealer that receives New Preferred Shares for its
own account pursuant to the Exchange Offer must acknowledge that it will deliver
a prospectus in connection with any resale of such New Preferred Shares. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of New Preferred Shares received in exchange for
Original Preferred Shares where such New Preferred Shares were acquired by such
broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that it will make this Prospectus
 
                                       30
<PAGE>   36
 
available to any broker-dealer for use in connection with any such resale for 90
days after the completion of this Exchange Offer. See "Plan of Distribution".
 
     Tendering holders of Original Preferred Shares will not be required to pay
brokerage commissions or fees or, subject to the instructions in the Letter of
Transmittal, transfer taxes with respect to the exchange of the Original
Preferred Shares pursuant to the Exchange Offer.
 
     Dividends on each New Preferred Share will accrue from the last date on
which dividends were paid on the Original Preferred Share surrendered in
exchange therefor or, if no dividend has been paid on such Original Preferred
Share, from the date of original issuance of such Original Preferred Share.
 
EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS
 
     The Exchange Offer expires on the Expiration Date.  The term "Expiration
Date" means 5:00 p.m., New York City time, on                     , 1998, unless
the Company in its sole discretion extends the period during which the Exchange
Offer is open, in which event the term "Expiration Date" means the latest time
and date on which the Exchange Offer, as so extended by the Company, expires.
The Company reserves the right to extend the Exchange Offer at any time and from
time to time prior to the Expiration Date by giving written notice to the
Exchange Agent and by timely public announcement communicated, unless otherwise
required by applicable law or regulation, by making a release to the Dow Jones
News Service. During any extension of the Exchange Offer, all Original Preferred
Shares previously tendered pursuant to the Exchange Offer will remain subject to
the Exchange Offer.
 
     The initial Exchange Date will be the first business day following the
Expiration Date. The Company expressly reserves the right to (i) terminate the
Exchange Offer and not accept for exchange any Original Preferred Shares for any
reason, including if any of the events set forth below under " --Conditions to
the Exchange Offer" shall have occurred and shall not have been waived by the
Company and (ii) amend the terms of the Exchange Offer in any manner, whether
before or after any tender of the Original Preferred Shares. If any such
termination or amendment occurs, the Company will notify the Exchange Agent in
writing and will either issue a press release or give written notice to the
holders of the Original Preferred Shares as promptly as practicable. Unless the
Company terminates the Exchange Offer prior to 5:00 p.m., New York City time, on
the Expiration Date, the Company will exchange the New Preferred Shares for the
Original Preferred Shares on the Exchange Date.
 
     If the Company waives any material condition to the Exchange Offer, or
amends the Exchange Offer in any other material respect, and if at the time that
notice of such waiver or amendment is first published, sent or given to holders
of Original Preferred Shares in the manner specified above, the Exchange Offer
is scheduled to expire at any time earlier than the expiration of a period
ending on the fifth business day from, and including, the date that such notice
is first so published, sent or given, then the Exchange Offer will be extended
until the expiration of such period of five business days.
 
     This Prospectus and the Letter of Transmittal and other relevant materials
will be mailed by the Company to record holders of Original Preferred Shares and
will be furnished to brokers, banks and similar persons whose names, or the
names of whose nominees, appear on the lists of holders for subsequent
transmittal to beneficial owners of Original Preferred Shares.
 
HOW TO TENDER
 
     The tender to the Company of Original Preferred Shares by a holder thereof
pursuant to one of the procedures set forth below will constitute an agreement
between such holder and the Company in accordance with the terms and subject to
the conditions set forth herein and in the Letter of Transmittal.
 
                                       31
<PAGE>   37
 
     General Procedures.  A holder of one or more Original Preferred Shares may
tender the same by (i) properly completing and signing the Letter of Transmittal
or a facsimile thereof (all references in this Prospectus to the Letter of
Transmittal shall be deemed to include a facsimile thereof) and delivering the
same, together with the certificate or certificates representing the Original
Preferred Share(s) being tendered and any required signature guarantees (or a
timely confirmation of a book-entry transfer (a "Book-Entry Confirmation")
pursuant to the procedure described below), to the Exchange Agent at its address
set forth below under "--Exchange Agent" on or prior to the Expiration Date or
(ii) complying with the guaranteed delivery procedures described below.
 
     If tendered Original Preferred Shares are registered in the name of the
signer of the Letter of Transmittal and the New Preferred Shares to be issued in
exchange therefor are to be issued (and any untendered Original Preferred Shares
are to be reissued) in the name of the registered holder, the signature of such
signer need not be guaranteed. In any other case, the tendered Original
Preferred Shares must be endorsed or accompanied by written instruments of
transfer in form satisfactory to the Company and duly executed by the registered
holder and the signature on the endorsement or instrument of transfer must be
guaranteed by a firm (an "Eligible Institution") that is a member of a
recognized signature guarantee medallion program (an "Eligible Program") within
the meaning of Rule 17Ad-15 under the Exchange Act. If the New Preferred Shares
and/or Original Preferred Shares not exchanged are to be delivered to an address
other than that of the registered holder appearing on the stock register for the
Original Preferred Shares, the signature on the Letter of Transmittal must be
guaranteed by an Eligible Institution.
 
     Any beneficial owner whose Original Preferred Shares are registered in the
name of a broker, dealer, commercial bank, trust company or other nominee and
who wishes to tender Original Preferred Shares should contact such holder
promptly and instruct such holder to tender Original Preferred Shares on such
beneficial owner's behalf. If such beneficial owner wishes to tender such
Original Preferred Shares himself or herself, such beneficial owner must, prior
to completing and executing the Letter of Transmittal and delivering such
Original Preferred Shares, either make appropriate arrangements to register
ownership of the Original Preferred Shares in such beneficial owner's name or
follow the procedures described in the immediately preceding paragraph. The
transfer of record ownership may take considerable time.
 
     Book-Entry Transfer.  The Exchange Agent has established an account with
respect to the Original Preferred Shares at The Depository Trust Company (the
"Book-Entry Transfer Facility") for purposes of the Exchange Offer, and any
financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Original Preferred Shares by
causing the Book-Entry Transfer Facility to transfer such Original Preferred
Shares into the Exchange Agent's account at the Book-Entry Transfer Facility in
accordance with the Book-Entry Transfer Facility's procedures for transfer.
However, although delivery of Original Preferred Shares may be effected through
book-entry transfer at the Book-Entry Transfer Facility, the Letter of
Transmittal, with any required signature guarantees and any other required
documents, must, in any case, be transmitted to and received by the Exchange
Agent at the address set forth below under "--Exchange Agent" on or prior to the
Expiration Date or the guaranteed delivery procedures described below must be
complied with.
 
     THE METHOD OF DELIVERY OF CERTIFICATES REPRESENTING ORIGINAL PREFERRED
SHARES AND ALL OTHER DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER. IF
SENT BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, RETURN RECEIPT REQUESTED,
BE USED, PROPER INSURANCE BE OBTAINED, AND THE MAILING BE MADE SUFFICIENTLY IN
ADVANCE OF THE EXPIRATION DATE TO PERMIT DELIVERY TO THE EXCHANGE AGENT ON OR
BEFORE THE EXPIRATION DATE.
 
     Unless an exemption applies under the applicable law and regulations
concerning "backup withholding" of federal income tax, the Exchange Agent will
be required to withhold, and will withhold, 31% of the gross proceeds otherwise
payable to a holder pursuant to the Exchange Offer if
 
                                       32
<PAGE>   38
 
the holder does not provide the holder's taxpayer identification number (social
security number or employer identification number) and certify that such number
is correct and, if required, that such holder is not subject to backup
withholding as a result of failing to report interest or dividend income. Each
tendering holder should complete and sign the main signature form and the
Substitute Form W-9 included as part of the Letter of Transmittal, so as to
provide the information and certification necessary to avoid backup withholding,
unless an applicable exemption exists and is proved in a manner satisfactory to
the Company and the Exchange Agent.
 
     Guaranteed Delivery Procedures.  If a holder desires to accept the Exchange
Offer and time will not permit a Letter of Transmittal or certificates
representing Original Preferred Shares to reach the Exchange Agent before the
Expiration Date, a tender may be effected if the Exchange Agent has received at
its office listed under "--Exchange Agent" on or prior to the Expiration Date a
letter, telegram or facsimile transmission from an Eligible Institution setting
forth the name and address of the tendering holder, the names in which the
Original Preferred Shares are registered and, if possible, the certificate
numbers of the Original Preferred Shares to be tendered, and stating that the
tender is being made thereby and guaranteeing that within three New York Stock
Exchange trading days after the date of execution of such letter, telegram or
facsimile transmission by the Eligible Institution, the Original Preferred
Shares, in proper form for transfer, will be delivered by such Eligible
Institution together with a properly completed and duly executed Letter of
Transmittal (and any other required documents). Unless Original Preferred Shares
being tendered by the above-described method (or a timely Book-Entry
Confirmation) are deposited with the Exchange Agent within the time period set
forth above (accompanied or preceded by a properly completed Letter of
Transmittal and any other required documents), the Company may, at its option,
reject the tender. Copies of a Notice of Guaranteed Delivery which may be used
by Eligible Institutions for the purposes described in this paragraph are being
delivered with this Prospectus and the Letter of Transmittal.
 
     A tender will be deemed to have been received as of the date when the
tendering holder's properly completed and duly signed Letter of Transmittal,
accompanied by the certificate representing the Original Preferred Shares (or a
timely Book-Entry Confirmation) is received by the Exchange Agent. Issuances of
New Preferred Shares in exchange for Original Preferred Shares tendered pursuant
to a Notice of Guaranteed Delivery or letter, telegram or facsimile transmission
to similar effect (as provided above) by an Eligible Institution will be made
only against deposit of the Letter of Transmittal (and any other required
documents) and the tendered Original Preferred Shares (or a timely Book-Entry
Confirmation).
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Original Preferred Shares
will be determined by the Company, whose determination will be final and
binding. The Company reserves the absolute right to reject any or all tenders
not in proper form or the acceptances for exchange of which may, in the opinion
of counsel to the Company, be unlawful. The Company also reserves the absolute
right to waive any of the conditions of the Exchange Offer or any defects or
irregularities in tenders of any particular holder whether or not similar
defects or irregularities are waived in the case of other holders. None of the
Company, the Exchange Agent or any other person will be under any duty to give
notification of any defects or irregularities in tenders or shall incur any
liability for failure to give any such notification. The Company's
interpretation of the terms and conditions of the Exchange Offer (including the
Letter of Transmittal and the instructions thereto) will be final and binding.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
     The Letter of Transmittal contains, among other things, the following terms
and conditions, which are part of the Exchange Offer:
 
     The party tendering Original Preferred Shares for exchange (the
"Transferor") exchanges, assigns and transfers the Original Preferred Shares to
the Company and irrevocably constitutes and
 
                                       33
<PAGE>   39
 
appoints the Exchange Agent as the Transferor's agent and attorney-in-fact to
cause the Original Preferred Shares to be assigned, transferred and exchanged.
The Transferor represents and warrants that it has full power and authority to
tender, exchange, assign and transfer the Original Preferred Shares and to
acquire New Preferred Shares issuable upon the exchange of such tendered
Original Preferred Shares, and that, when the same are accepted for exchange,
the Company will acquire good and unencumbered title to the tendered Original
Preferred Shares, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim. The Transferor also warrants
that it will, upon request, execute and deliver any additional documents deemed
by the Company to be necessary or desirable to complete the exchange, assignment
and transfer of tendered Original Preferred Shares. The Transferor further
agrees that acceptance of any tendered Original Preferred Shares by the Company
and the issuance of New Preferred Shares in exchange therefor shall constitute
performance in full by the Company of its obligations under the Registration
Agreement and that the Company shall have no further obligations or liabilities
thereunder (except in certain limited circumstances). All authority conferred by
the Transferor will survive the death or incapacity of the Transferor and every
obligation of the Transferor shall be binding upon the heirs, legal
representatives, successors, assigns, executors and administrators of such
Transferor.
 
     By tendering Original Preferred Shares, the Transferor certifies (a) that
it is not an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act, that it is not a broker-dealer that owns Original Preferred
Shares acquired directly from the Company or an affiliate of the Company, that
it is acquiring the New Preferred Shares offered hereby in the ordinary course
of such Transferor's business and that such Transferor has no arrangement with
any person to participate in the distribution of such New Preferred Shares; or
(b) that it is an "affiliate" (as so defined) of the Company or of the
Purchasers, and that it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable to it. Each
broker-dealer that receives New Preferred Shares for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Preferred Shares. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
 
WITHDRAWAL RIGHTS
 
     Original Preferred Shares tendered pursuant to the Exchange Offer may be
withdrawn at any time prior to the Expiration Date.
 
     For a withdrawal to be effective, a written or facsimile transmission
notice of withdrawal must be timely received by the Exchange Agent at its
address set forth below under "--Exchange Agent". Any such notice of withdrawal
must specify the person named in the Letter of Transmittal as having tendered
Original Preferred Shares to be withdrawn, the certificate numbers of Original
Preferred Shares to be withdrawn, the number of Original Preferred Shares to be
withdrawn, a statement that such holder is withdrawing his or her election to
have such Original Preferred Shares exchanged, and the name of the registered
holder of such Original Preferred Shares; and must be signed by the holder in
the same manner as the original signature on the Letter of Transmittal
(including any required signature guarantees) or be accompanied by evidence
satisfactory to the Company that the person withdrawing the tender has succeeded
to the beneficial ownership of the Original Preferred Shares being withdrawn.
The Exchange Agent will return the properly withdrawn Original Preferred Shares
promptly following receipt of notice of withdrawal. All questions as to the
validity of notices of withdrawals, including time of receipt, will be
determined by the Company, and such determination will be final and binding on
all parties.

ACCEPTANCE OF ORIGINAL PREFERRED SHARES FOR EXCHANGE; DELIVERY OF NEW PREFERRED
SHARES
 
     Upon the terms and subject to the conditions of the Exchange Offer, the
acceptance for exchange of Original Preferred Shares validly tendered and not
withdrawn and the issuance of the New Preferred Shares will be made on the
Exchange Date. For the purposes of the Exchange Offer, the Company shall be
deemed to have accepted for exchange validly tendered Original Preferred Shares
when, as and if the Company has given written notice thereof to the Exchange
Agent.
 
     The Exchange Agent will act as agent for the tendering holders of Original
Preferred Shares for the purposes of receiving New Preferred Shares from the
Company and causing the Original Preferred Shares to be assigned, transferred
and exchanged. Upon the terms and subject to the conditions of the Exchange
Offer, delivery of New Preferred Shares to be issued in exchange for accepted
Original Preferred Shares will be made by the Exchange Agent promptly after
acceptance of the tendered Original Preferred Shares. Original Preferred Shares
not accepted for exchange by the Company will be returned without expense to the
tendering holders (or in the case of Original Preferred Shares tendered by
book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer
Facility pursuant to the procedures described above, such non-exchanged Original
Preferred Shares will be credited to an account maintained with such Book-Entry
Transfer Facility) promptly following the Expiration Date or, if the Company
terminates the Exchange Offer prior to the Expiration Date, promptly after the
Exchange Offer is so terminated.
 
CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other provision of the Exchange Offer, or any extension
of the Exchange Offer, the Company will not be required to issue New Preferred
Shares in respect of any properly tendered Original Preferred Shares not
previously accepted and may terminate the Exchange Offer (by oral or written
notice to the Exchange Agent and by timely public announcement communicated,
unless otherwise required by applicable law or regulation, by making a release
to the Dow Jones News Service) or, at its option, modify or otherwise amend the
Exchange Offer, if (a) there shall be threatened, instituted or pending any
action or proceeding before, or any injunction, order or decree shall have been
issued by, any court or governmental agency or other governmental regulatory or
administrative agency or commission, (i) seeking to restrain or prohibit the
making or consummation of the Exchange Offer or any other transaction
contemplated by the Exchange Offer, (ii) assessing or seeking any damages as a
result thereof, or (iii) resulting in a material delay in the ability of the
Company to accept for exchange or to exchange some or all of the Original
Preferred Shares pursuant to the Exchange Offer; (b) any statute, rule,
regulation, order or injunction shall be sought, proposed, introduced, enacted,
promulgated or deemed applicable to the Exchange Offer or any of the
transactions contemplated by the Exchange Offer by any government or
governmental authority, domestic or foreign, or any action shall have been
taken, proposed or threatened, by any government, governmental authority, agency
or court, domestic or foreign, that in the sole judgment of the Company might
directly or indirectly result in any of the consequences referred to in clauses
(a)(i) or (ii) above or, in the sole judgment of the Company, might result in
the holders of New Preferred Shares having obligations with respect to resales
and transfers of New Preferred Shares which are greater than those described in
the interpretations of the Commission referred to on the cover page of this
Prospectus, or would otherwise make it inadvisable to proceed with the Exchange
Offer; or (c) a material adverse change shall have occurred in the business,
condition (financial or otherwise), operations, or prospects of the Company.
 
     The foregoing conditions are for the sole benefit of the Company and may be
asserted by it with respect to all or any portion of the Exchange Offer
regardless of the circumstances (including any action or inaction by the
Company) giving rise to such condition or may be waived by the Company in whole
or in part at any time or from time to time in its sole discretion. The failure
by the Company at any time to exercise any of the foregoing rights will not be
deemed a waiver of any such right, and each right will be deemed an ongoing
right which may be asserted at any time or from time to time.
 
                                       35
<PAGE>   41
 
In addition, the Company has reserved the right, notwithstanding the
satisfaction of each of the foregoing conditions, to terminate or amend the
Exchange Offer.
 
     Any determination by the Company concerning the fulfillment or
non-fulfillment of any conditions will be final and binding upon all parties.
 
     In addition, the Company will not accept for exchange any Original
Preferred Shares tendered and no New Preferred Shares will be issued in exchange
for any such Original Preferred Shares, if at such time any stop order shall be
threatened or in effect with respect to the Registration Statement of which this
Prospectus constitutes a part.

     Delivery to an address other than as set forth herein, or transmissions of

SOLICITATION OF TENDERS; EXPENSES
 
     The Company has not retained any dealer-manager or similar agent in
connection with the Exchange Offer and will not make any payments to brokers,
dealers or others for soliciting acceptances of the Exchange Offer. The Company
will, however, pay the Exchange Agent reasonable and customary fees for its
services and will reimburse it for reasonable out-of-pocket expenses in
connection therewith. The Company will also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding tenders for their customers. The expenses to be
incurred in connection with the Exchange Offer, including the fees and expenses
of the Exchange Agent and printing, accounting and legal fees, will be paid by
the Company and are estimated at approximately $300,000.
 
     No person has been authorized to give any information or to make any
representations in connection with the Exchange Offer other than those contained
in this Prospectus. If given or made, such information or representations should
not be relied upon as having been authorized by the Company. Neither the
delivery of this Prospectus nor any exchange made hereunder shall, under any
circumstances, create any implication that there has been no change in the
affairs of the Company since the respective dates as of which information is
given herein. The Exchange Offer is not being made to (nor will tenders be
accepted from or on behalf of) holders of Original Preferred Shares in any
jurisdiction in which the making of the Exchange Offer or the acceptance thereof
would not be in compliance with the laws of such jurisdiction. However, the
Company may, at its discretion, take such action as it may deem necessary to
make the Exchange Offer in any such jurisdiction and extend the Exchange Offer
to holders of Original Preferred Shares in such jurisdiction. In any
jurisdiction the securities laws or blue sky laws of which require the Exchange
                                       36
<PAGE>   42
 
Offer to be made by a licensed broker or dealer, the Exchange Offer is being
made on behalf of the Company by one or more registered brokers or dealers which
are licensed under the laws of such jurisdiction.
 
APPRAISAL RIGHTS
 
     HOLDERS OF ORIGINAL PREFERRED SHARES WILL NOT HAVE DISSENTERS' RIGHTS OR
APPRAISAL RIGHTS IN CONNECTION WITH THE EXCHANGE OFFER.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     U.S. holders (as defined) should not recognize any taxable gain or loss for
federal income tax purposes as a result of the exchange of Original Preferred
Shares for New Preferred Shares.
 
OTHER
 
     Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Original Preferred Shares
are urged to consult their financial and tax advisors in making their own
decisions on what action to take.
 
     As a result of the making of, and upon acceptance for exchange of all
validly tendered Original Preferred Shares pursuant to the terms of this
Exchange Offer, the Company will have fulfilled a covenant contained in the
Certificate of Designation and the Registration Agreement. Holders of the
Original Preferred Shares who do not tender their certificates in the Exchange
Offer will continue to hold such certificates and will be entitled to all the
rights, and limitations applicable thereto, under the Certificate of
Designation, except for any such rights under the Registration Agreement which
by their terms terminate or cease to have further effect as a result of the
making of this Exchange Offer. See "Description of the Series A Preferred
Stock". All untendered Original Preferred Shares will continue to be subject to
the restrictions on transfer set forth in the Certificate of Designation. To the
extent that Original Preferred Shares are tendered and accepted in the Exchange
Offer, the trading market, if any, for the Original Preferred Shares could be
adversely affected. See "Risk Factors--Consequences of Failure to Exchange".
 
     The Company may in the future seek to acquire untendered Original Preferred
Shares in open-market or privately negotiated transactions, through subsequent
exchange offers or otherwise. The Company has no present plan to acquire any
Original Preferred Shares which are not tendered in the Exchange Offer.

(1) EBITDA consists of net income (loss) before interest and other income,
    income taxes, depreciation and amortization. It is a financial performance
    measure commonly used in the telecommunications industry and is presented to
    assist in an understanding of the Company's operating results. However, it
    is not intended to represent cash flows or results of operations in
    accordance with generally accepted accounting principles ("GAAP").
 
(2) For purposes of calculating the ratio of earnings to fixed charges,
    "earnings" represent net income before income taxes plus fixed charges, and
    "fixed charges" consist of interest expense. For the year ended 1997,
    earnings were insufficient to cover fixed charges by $3.1 million.
 
(3) Gives effect to (i) the Initial Offering (after deducting discounts and
    offering expenses payable by the Company, estimated to total $2.5 million)
    and the receipt of the estimated net cash proceeds therefrom, including the
    repayment of $1.9 million of borrowings under the Existing Bank Credit
    Facility and (ii) the payment of a $5.0 million dividend to the Company's
    stockholders and the reinvestment of $1.9 million by one of the Company's
    stockholders (representing such stockholder's approximate net after-tax
    proceeds of the dividend) in the form of a long-term loan to the Company.
    See "Use of Proceeds" and "Description of Certain
    Indebtedness -- Stockholder Loan".
 
(4) Series A Preferred Stock with an initial liquidation preference of $40
    million was issued by the Company as part of the Units offered in the
    Initial Offering. Each Unit consisted of one share of Series A Preferred
    Stock, 7.75 Initial Warrants and 15 Contingent Warrants, each Warrant to
    purchase one share of Common Stock. An assumed initial value of $4.65
    million was allocated to additional paid-in capital, representing the
    portion of the purchase price of the Units allocated to the Initial
    Warrants, less $0.3 million of the costs associated with the Initial
    Offering, allocable to the Initial Warrants. No assurance can be given that
    the value allocated to the Initial Warrants will be indicative of the price
    at which the Initial Warrants may actually trade. Costs of $2.2 million
    associated with the Initial Offering have been allocated to the Series A
    Preferred Stock.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the financial statements and related notes and other detailed information
regarding the Company included elsewhere in this Prospectus. The discussion and
analysis contains statements of a forward-looking nature relating to future
events or the future financial performance of the Company. Actual events or
results may differ materially from such statements. In evaluating such
statements, prospective investors should specifically consider the various
factors identified in this Prospectus, including the matters set forth under the
caption "Risk Factors", which could cause actual results to differ materially
from those indicated in the forward-looking statements contained herein.
 
OVERVIEW
 
     The Company was founded in 1990 as an aggregator of AT&T long distance
services, reselling AT&T branded products primarily to small and medium-sized
businesses. As an aggregator of AT&T services, customers were billed and
serviced by AT&T. The Company derived its profits through 1993 by obtaining
volume discounts on bulk purchases of long distance services from AT&T and
passing along a portion of these discounts to its customers.
 
     In 1993, the Company entered into an agreement with Sprint and in 1994
began to resell Sprint telecommunications services. As a reseller of Sprint, the
Company began provisioning, servicing and billing customers under the Network
Plus name. Volume discounts offered by Sprint enabled the Company to offer
low-cost, high quality, long distance services at favorable rates to its
customers. In addition, by servicing its own customers, the Company was better
able to meet customer needs and control costs.
 
     In mid-1996, in addition to provisioning customer traffic onto Sprint's
network ("off-net" traffic) as a switchless reseller of Sprint long distance
services, the Company initiated the deployment of its own long distance network
and began operating as a switch-based provider in certain states, switching
customer traffic on its own facilities ("on-net" traffic). The Company's
decision to deploy switches was based on economic efficiencies resulting from
customer concentrations and traffic patterns. Installation of telephony switches
was completed in Quincy, Massachusetts in June 1996, servicing the Northeastern
region of the United States, and Orlando, Florida in November 1997, servicing
the Southeastern region of the United States. As a switch-based provider, the
Company is able to lower its direct transmission costs. Expansion of the
Company's existing network is planned in those areas of the United States in
which the Company already has significant volumes of originating or terminating
traffic. Additional interexchange, international and local switches are planned
for installation throughout the second half of 1998 and continuing through 1999.
The Company has also sold international wholesale services since 1997. The
Company recently entered into two 20-year indefeasible right-of-use ("IRU")
agreements pursuant to which it acquired 625 route miles of dark fiber (1,830
digital fiber miles). When the fiber is fully deployed and activated, it will
form a redundant fiber ring connecting major markets throughout New England and
the New York metropolitan area, providing the Company with significant
transmission capacity. See "Business -- Network -- Current Network -- Fiber and
Transport".
 
     The Company intends to continue to add services to maintain and enhance its
position as an integrated communications provider ("ICP"). The Company's
strategic initiatives in 1998 include expanding its service offerings to include
local exchange and Internet services. By providing local exchange and Internet
services, the Company will offer a single source solution for all of the
telecommunication needs of its customers. By expanding its service offerings,
the Company believes it can improve customer retention and market share, while
simultaneously reducing overall transmission costs.
 
     The Company sells its services through a direct retail sales force, an
international wholesale sales force and a reseller and independent agent sales
force. In 1998 and 1999, as the Company


                                       40
<PAGE>   46
 
expands its network facilities, the Company intends to increase its sales force
to approximately 400 members. The investment in the sales force, expansion of
the existing network and addition of local exchange, Internet and other services
will require significant expenditures, a substantial portion of which will be
incurred before related revenue is realized. As these expansion plans are
undertaken and the revenue base grows, periods of operating losses and negative
cash flows from operations are anticipated through at least the first three
quarters of 1999. See "Risk Factors -- Negative Cash Flow and Operating Losses"
and "-- Substantial Future Capital Requirements; Need for Additional Financing;
Substantial Leverage".
 
RESULTS OF OPERATIONS
 
     The following table sets forth for the periods indicated certain financial

  THREE MONTHS ENDED JUNE 30, 1998 COMPARED TO THREE MONTHS ENDED JUNE 30, 1997
 
     Revenue.  Revenue increased 10.1% to $27.1 million for the three months
ended June 30, 1998 from $24.6 million for the three months ended June 30, 1997.
Revenue for the three months ended June 30, 1997 included approximately $3.8
million from two customers with whom the Company did not do business in 1998.
One was a high volume, low margin customer until termination in December 1997,
and the other was a specialized international customer with whom the Company
terminated its service agreement in October 1997 due to collection problems.
Exclusive of the revenue from these two former customers, revenue increased by
30.3% from period to period. The Company's customers totaled approximately
34,000 at June 30, 1998 and 26,000 at June 30, 1997. The components of revenue
in each year reflect the Company's initiative to become a facilities-based
services provider. In the three months ended June 30, 1998, on-net revenue and
on-net billed customer minutes were 57.7% and 47.1%, respectively, of total
revenue and minutes. In the three months ended June 30, 1997, the corresponding
on-net revenue and minutes represented 17.4% and 17.5%, respectively, of total
revenue and minutes. It is expected that long distance minutes and revenue
attributable to on-net customer traffic will exceed 75% of the totals by the
first quarter of 1999. The Company also anticipates that revenue growth will
progressively increase in each remaining quarter of 1998 as a result of a
significant increase in the size of the Company's direct sales force.
 
     Gross Profit.  Gross profit for the three months ended June 30, 1998
totaled $7.1 million, an increase of 33.9% from the $5.3 million earned in the
corresponding period in 1997. Gross margin increased to 26.2% in 1998 from 21.6%
in 1997, reflecting the increase in on-net traffic, the reduced costs of
carrying off-net traffic and a reduction in costs of originating and terminating
traffic.
 
                                       41
<PAGE>   47
 
     On-net revenue, as described above, increased significantly as a percentage
of total revenue. Gross margin earned on domestic on-net revenue greatly exceeds
that of off-net revenue. On-net gross margin, however, combines margins earned
on domestic traffic and lower-margin international wholesale traffic.
International wholesale traffic is expected to grow at rates in excess of
domestic traffic, which will lower the overall future gross margin on on-net
traffic. Costs of originating and terminating traffic have declined as a result
of provisions mandated by the Telecommunications Act of 1996.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased by 17.5% to $6.4 million for the three months ended June 30,
1998 from $5.4 million for the three months ended June 30, 1997, and increased
as a percentage of revenue to 23.6% from 22.1% for the corresponding periods.
Within selling, general and administrative expenses, the largest component is
personnel and related expenses, which combines all wages and salaries, along
with commissions earned by the Company's sales force. These expenses increased
by 19.1% from 1997 to 1998, reflecting an increase in the number of employees.
Other expenses within selling, general and administrative expenses increased as
a result of the Company's ongoing growth.
 
     In April 1998, the Company commenced its initiative to expand its 96-member
sales force and, as of June 30, 1998, the sales force had increased to 152
members. The Company expects to further expand its sales force to approximately
230 by year end 1998 and to approximately 400 by year end 1999. Variable
expenses, including commissions paid to independent marketing representatives
and the provision for doubtful accounts, are expected to increase with future
sales growth. In addition, the Company expects to expend a significant amount of
funds in 1998 towards the recruitment of personnel, marketing, advertising and
promotion, and professional services in conjunction with its growth plans and
initiatives to expand its service offerings. It is expected that there will be a
time lag between the incurring of these expenses and any resulting increase in
revenue. See "Risk Factors -- Management of Growth".
 
     Depreciation and Amortization.  Depreciation and amortization increased to
$483,000 for the three months ended June 30, 1998 from $168,000 for the three
months ended June 30, 1997, reflecting the Company's network build out and
capital additions to the Company's internal computer systems. Future
depreciation expense will increase as assets related to the Company's network
expansion plans are placed into service.
 
     Interest.  Interest expense, net of interest income, increased to $284,000
for the three months ended June 30, 1998 from $55,000 for the three months ended
June 30, 1997. This increase resulted from interest on capital leases entered
into in the latter half of 1997 to finance network additions and internal
computer systems, interest incurred related to notes payable entered into in
December 1997, and additional interest related to higher levels of revolving
credit borrowings in 1998.
 
     Income Taxes.  In the three months ended June 30, 1998, income taxes of
$125,000 were provided, principally for state franchise tax assessments. No
provision was required in the corresponding 1997 period.
 
     Net Loss.  As a result of the aforementioned increases in revenue,
operating expenses, depreciation and amortization, interest income and expense,
the Company incurred a net loss of $156,000 for the three months ended June 30,
1998, compared to net loss of $332,000 for the three months ended June 30, 1997.
 
     EBITDA.  Earnings before other income and expense, interest, taxes,
depreciation and amortization ("EBITDA") increased $849,000 to $720,000 for the
three months ended June 30, 1998 from negative EBITDA of $129,000 for the three
months ended June 30, 1997. This increase was due to the changes in revenues,
network development, operations and selling, general and administrative expenses
discussed above.

  SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997
 
     Revenue.  Revenue increased 5.9% to $52.3 million for the six months ended
June 30, 1997 from $49.4 million for the six months ended June 30, 1997. Revenue
for the six months ended June 30, 1997 included approximately $6.7 million from
two customers, described above, with whom the Company did not do business in
1998. Exclusive of the revenue from these two former customers, revenue
increased by 22.5% from period to period. The components of revenue in each year
reflect the Company's initiative to become a facilities-based services provider.
In the six months ended June 30, 1998, on-net revenue and on-net billed customer
minutes were 54.0% and 43.8%, respectively, of total revenue and minutes. In the
six months ended June 30, 1997, the corresponding on-net revenue and minutes
represented 13.5% and 14.7%, respectively, of total revenue and minutes.
 
     Gross Profit.  Gross profit for the six months ended June 30, 1998 totaled
$13.5 million, an increase of 23.2% from the $10.9 million earned in the
corresponding period in 1997. Gross margin improved to 25.8% in 1998 from 22.2%
in 1997, reflecting the increase in on-net traffic, the reduced costs of
carrying off-net traffic and a reduction in costs of originating and terminating
traffic. Costs of originating and terminating traffic have declined as a result
of provisions mandated by the Telecommunications Act of 1996.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased by 12.9% to $11.9 million for the six months ended June 30,
1998 from $10.6 million for the six months ended June 30, 1997, and increased as
a percentage of revenue to 22.8% from 21.4% for the corresponding periods.
Within selling, general and administrative expenses, the largest component is
personnel and related expenses, which combines all wages and salaries, along
with commissions earned by the Company's sales force. These expenses increased
by 11.4% from 1997 to 1998, reflecting an increase in the number of employees.
In April 1998, the Company commenced its initiative to expand its 96 member
sales force, and as of June 30, 1998, the sales force had increased to 152
members. Other expenses within selling, general and administrative expenses
increased as a result of the Company's ongoing growth.
 
     Depreciation and Amortization.  Depreciation and amortization increased to
$951,000 for the six months ended June 30, 1998 from $324,000 for the six months
ended June 30, 1997, reflecting the Company's network build out and capital
additions to the Company's internal computer systems.
 
     Interest.  Interest expense, net of interest income, increased to $566,000
for the six months ended June 30, 1998 from $116,000 for the six months ended
June 30, 1997. This increase resulted from interest on capital leases entered
into in the latter half of 1997 to finance network additions and internal
computer systems, interest incurred related to notes payable entered into in
December 1997, and additional interest related to higher levels of revolving
credit borrowings in 1998.
 
     Income Taxes.  In the six months ended June 30, 1998, income taxes of
$134,000 were provided, principally for state franchise tax assessments. Income
taxes in the comparable period of 1997 totaled $25,000.
 
     Net Loss.  As a result of the aforementioned increases in revenue,
operating expenses, depreciation and amortization, interest income and expense,
the Company incurred a net loss of $72,000 for the six months ended June 30,
1998, compared to net loss of $55,000 for the six months ended June 30, 1997.
 
     EBITDA.  EBITDA increased $1,168,000 to $1,542,000 for the six months ended
June 30, 1998 from $374,000 for the six months ended June 30, 1997. This
increase was due to the changes in revenues, network development, operations and
selling, general and administrative expenses discussed above.

<PAGE>   49
 
  YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
     Revenue.  Revenue increased by 30.7% to $98.2 million in 1997 from $75.1
million in 1996, primarily related to an increase in the Company's customer
base. The Company's customers totaled approximately 30,000 at the end of 1997
and 19,000 at the end of 1996. Revenue in 1996 also included approximately $1.8
million related to the amortization of credits received through AT&T sales
promotions on three-year contracts that were fully amortized by year end 1996.
 
     Gross Profit.  Gross profit increased to $20.1 million in 1997 from $17.9
million in 1996, a 12.1% increase, but gross margin declined to 20.5% in 1997
from 23.9% in 1996. The decline in gross margin resulted from several factors.
Gross profit in 1996 included $1.8 million of nonrecurring revenue derived from
the amortization of the AT&T credits described above. In mid-1996, the Company
began to operate its own network, incurring start up costs related to investment
in these facilities. The first network switch, deployed in Quincy, Massachusetts
in June 1996, did not begin to carry any significant traffic until late 1996. A
second switch, deployed in Orlando, Florida in November 1997, did not carry any
significant traffic in 1997. In 1997, the Company began to transmit
international traffic through the Quincy switch, which generates margins
significantly below domestic on-net traffic. In addition, initiatives undertaken
to provision existing customer traffic from off-net to on-net generally did not
commence until the latter part of 1997 and, consequently, the improved margins
generated by on-net traffic did not significantly impact the results for the
year. Finally, increased competition in the long distance telecommunications
industry resulted in slightly lower pricing in 1997, as compared to 1996.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased by 33.7% to $25.7 million in 1997 from $19.2 million in 1996,
and increased as a percentage of revenue to 26.2% in 1997 from 25.6% in 1996.
Personnel and related expenses, the largest component of selling, general and
administrative expenses, decreased by 1.5% from 1996 to 1997. A decrease in the
direct sales force was principally offset by an expansion of administrative
services, including customer service and provisioning personnel, to support the
revenue growth. Sales offices were added in 1997 in conjunction with the
November 1997 deployment of the Company's switch in Orlando, Florida. Other
selling, general and administrative expenses also increased as a result of the
revenue and personnel growth, including rent and utilities for additional
offices and commissions paid to independent marketing representatives. The
provision for doubtful accounts increased by $3.0 million in 1997 from 1996,
principally relating to two customers and an increase in the estimate of the bad
debt reserve proportionate to the increase in revenue.
 
     Depreciation and Amortization.  Depreciation and amortization expense
increased to $994,000 in 1997 from $533,000 in 1996 as a result of capital
additions for the Company's network build-out and internal computer systems. The
Company's internal computer hardware was significantly upgraded in November
1997. Future depreciation expense will increase as assets related to the
Company's network expansion plans are placed into service.
 
     Interest.  Interest expense, net of interest income, increased from
$217,000 in 1996 to $471,000 in 1997. This interest relates to a higher level of
revolving credit borrowings in 1997, interest on capital leases entered into in
the latter half of 1997 and interest incurred related to notes payable entered
into in December 1997.
 
     Other Income (Expense).  Other income totaled $3.9 million in 1997 and $3.5
million in 1996, both principally related to warrants, as follows. In 1995,
warrants to purchase shares of Tel-Save Holdings, Inc. ("Tel-Save") common stock
were received as partial consideration from a sale of customer billing bases.
During 1996, the Company met the sales volume obligations to exercise a portion
of the outstanding warrants. Certain of these warrants were exercised and common
stock related to those warrants was sold by the Company, resulting in net
proceeds and other income of $1.4 million. The remainder of the warrants that
became exercisable in 1996 were subsequently exercised in 1997. These warrants
were classified as investments and were valued at approximately $2.1 million at
December 31, 1996 using an established valuation model, for a total of $3.5
million recorded as other income in 1996.
 
                                       44
<PAGE>   50
 
     The agreements between Tel-Save and the Company required the transfer of
ownership of the common stock certificates from Tel-Save to the Company upon the
Company meeting certain requirements, which the Company, based upon available
information, believed it had met in 1996 and 1997. Accordingly, in 1997, cash
payments totaling $3.6 million were made to exercise all outstanding warrants.
In total, payments for warrants in 1997 were believed to entitle the Company to
765,000 shares of Tel-Save common stock, subject to the registration of the
shares by Tel-Save. The shares were registered with the Securities and Exchange
Commission in November 1997, but common stock certificates were not physically
transferred to the Company.
 
     In order to take physical possession of the Tel-Save common stock
certificates, the Company filed suit against Tel-Save in January 1998. On June
24, 1998 a settlement agreement was signed between the parties pursuant to which
Tel-Save returned $1.5 million paid by the Company during 1997 in its attempt to
exercise the final warrant for 315,000 shares, and canceled that warrant. In
addition, Tel-Save issued the remaining 450,000 shares to the Company and
simultaneously repurchased such shares for $8.0 million. There will be no
continuing obligations between the parties. Accordingly, the Company's
investment in Tel-Save at December 31, 1997 was valued at the $9.5 million
received pursuant to the settlement, and other income of $3.8 million was
recorded in 1997 to reflect this valuation.
 
     Net Loss.  As a result of the aforementioned increases in revenue,
operating expenses, depreciation and amortization, interest income and expense,
the Company incurred a net loss of $3.2 million for the year ended December 31,
1997, compared to net income of $1.4 million for the year ended December 31,
1996.
 
     EBITDA.  EBITDA was $(5.6) million for the year ended December 31, 1997
compared to $(1.3) million for the year ended December 31, 1996. This decline
was due to the changes in revenue, network development, operations and selling,
general and administrative expenses discussed above.
 
  YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     Revenue.  Revenue increased by 53.2% to $75.1 million in 1996 from $49.0
million in 1995, primarily related to an increase in the customer base. The
Company's customers totaled approximately 19,000 at the end of 1996 and 9,000 at
the end of 1995. In 1995, the Company's revenue was entirely generated from
off-net traffic. In 1996, the Company installed its first network switch, but
less than 1% of 1996 revenue was generated on-net. Revenue in 1996 and 1995 also
included approximately $1.8 million and $3.3 million, respectively, related to
the amortization of credits received through AT&T sales promotions.
 
     Gross Profit.  Gross profit increased to $17.9 million in 1996 from $14.0
million in 1995, a 28.4% increase, but gross margin declined to 23.9% in 1996
from 28.5% in 1995. The decline in gross margin resulted from the inclusion of
non-recurring AT&T credits of $3.3 million in 1995 as compared to $1.8 million
in 1996. Also contributing to the margin decline were start up costs in 1996
related to the installation of the Company's first network switch, which was
deployed in June 1996.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased by 8.6% to $19.2 million in 1996 from $17.7 million in 1995,
but decreased as a percentage of revenue to 25.6% in 1996 from 36.1% in 1995.
Personnel and related expenses, the largest component of selling, general and
administrative expenses, decreased by 6.7% from 1995 to 1996, reflecting a
decrease in the direct retail sales force. Other selling, general and
administrative expenses increased as a result of revenue growth.
 
     Depreciation and Amortization.  Depreciation and amortization increased to
$539,000 in 1996 from $276,000 in 1995, related to $2.1 million of capital
expenditures in 1996, including $1.5 million for switching equipment.
 
     Interest Expense.  In 1996, when the Company entered into and first began
to borrow under its Existing Bank Credit Facility, net interest expense
resulted, totaling $217,000. In 1995, the Company
 
                                       45
<PAGE>   51
 
did not have any revolving credit borrowings and generated interest income, net
of interest expense on long-term debt, of $162,000.
 
     Other Income.  Other income totaled $3.5 million in 1996 and $7.9 million
in 1995. In 1995, the Company sold three separate billing bases of customer
accounts to other telecommunications companies for cash totaling approximately
$8.4 million, recorded as other income, and warrants to purchase shares of
Tel-Save common stock. No value was ascribed to the warrants in 1995. In 1996,
$1.4 million of other income was related to the exercise of warrants and
subsequent sale of Tel-Save common stock. An additional $2.1 million was
recorded as other income primarily related to the value ascribed to additional
warrants that became exercisable in 1996.
 
     Net Income.  As a result of the aforementioned increases in revenue,
operating expenses, depreciation and amortization, and interest income and
expense, net income decreased $2.3 million, or 62%, to $1.4 million for the year
ended December 31, 1996, from $3.7 million for the year ended December 31, 1995.
 
     EBITDA.  EBITDA was $(1.3) million for the year ended December 31, 1996
compared to $(3.7) million for the year ended December 31, 1995. This decrease
was due to the changes in revenue, network development, operations and selling,
general and administrative expenses discussed above.

     The Company could experience quarterly variations in revenue and operating
income as a result of many factors, including the introduction of new services
by the Company, actions taken by competitors, the timing of the acquisition or
loss of customers, the timing of additional selling, general and administrative
expenses incurred to acquire and support new or additional business and changes
in the Company's revenue mix among its various service offerings. Many of the
factors that could cause such variations are outside of the Company's control.
The Company plans its operating expenditures based on revenue forecasts, and a
revenue shortfall below such forecasts in any quarter could adversely affect the
Company's operating results for that quarter.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  OVERVIEW OF HISTORICAL CASH REQUIREMENTS
 
     Since commencing operations in 1990, the Company has experienced
significant growth. Prior to 1994, the Company operated solely as an aggregator
of AT&T services and funded its growth principally with cash provided from
operating activities. In 1994, the Company became a reseller of Sprint services,
requiring additional funding to support the development of an infrastructure to
support provisioning, billing and servicing of customers billed under the
Network Plus name. Cash requirements in 1994 and 1995 were financed primarily by
cash credits received in 1993 and 1994 under AT&T promotions and by the sales of
portions of the Company's customer accounts to other telecommunications
companies in 1995. These sales resulted in the receipt by the Company of a cash
payment of $8.4 million and warrants to purchase common stock of Tel-Save. In
1996, the Company further expanded its infrastructure and began to deploy its
own network. To support 1996 cash requirements, NPI entered into a $7.0 million
revolving credit agreement with Fleet National Bank ("Fleet") and a term loan
for $1.0 million with Fleet to allow for its initial purchase of network
 
                                       47
<PAGE>   53
 
facilities, and entered into a financing transaction involving the sale and
lease back of the Quincy switch. Cash flows in 1996 were supplemented by the
exercise of Tel-Save warrants and the subsequent sale of the underlying common
stock, resulting in total net proceeds of $1.4 million.
 
     In 1997, the Company continued to expand its network and infrastructure. In
addition, $3.6 million was expended to exercise additional warrants for common
stock of Tel-Save. Cash needs in 1997 were met through the addition of capital
leases, including a financing transaction involving the sale and lease back of
the Orlando switch, utilization of the existing revolving credit facility,
refinancing of a portion of accounts payable to Sprint into a short-term
promissory note (the "Sprint Note") and receipt of loans totaling $1.8 million
from the Company's stockholders (the "Stockholder Loans").
 
     On April 30, 1998, NPI entered into the Existing Bank Credit Facility, a
$23.0 million revolving credit agreement with Fleet. Borrowings under this line
were used to repay the Sprint Note and the Stockholder Loans.
 
     On August 14, 1998, the Company entered into a commitment letter with
Goldman Sachs Credit Partners L.P. for the New Revolving Credit Facility. The
New Revolving Credit Facility is a $60 million facility, concurrent with the
closing of which the Company expects to terminate the Existing Bank Credit
Facility. The New Revolving Credit Facility will have a term of 18 months. Under
the New Revolving Credit Facility, up to $60 million will be available, $30
million of which will be available based upon a percentage of accounts
receivable. Interest will be payable at one percent above the prime rate. The
New Revolving Credit Facility will require the Company to meet, among other
things, minimum levels of revenues, access lines in service and EBITDA. See
"Description of Certain Indebtedness -- New Revolving Credit Facility".
 
     The Company consummated the offering of Units including the Original
Preferred Shares (the "Initial Offering") on September 3, 1998. The net proceeds
to the Company of the Initial Offering, after deducting commissions and
estimated offering expenses, were approximately $37.5 million. The Company
expects to use these proceeds to finance the Company's anticipated expansion,
including the expansion of its local telecommunications infrastructure,
information technology systems and sales force; for working capital; and to
repay outstanding borrowings under the Existing Bank Credit Facility.
 
     Prior to the Initial Offering, the Company was an S Corporation and, as a
result, did not pay corporate federal income taxes. Instead, the Company's
stockholders were liable for their share of taxes in respect of the Company's
taxable income. The Company had similar tax status in certain states that
recognize S corporation status. Accordingly, each year prior to 1998 the Company
distributed and for the period prior to August 1998, the Company will
distribute, to its stockholders cash in amounts sufficient to enable the
Company's stockholders to pay federal and state taxes on income of the Company
attributable to the stockholders and related tax preparation expenses. During
the years ended December 31, 1997, 1996 and 1995, the Company distributed an
aggregate of $601,000, $1.2 million and $1.9 million, respectively, to its
stockholders.
 
  FINANCIAL CONDITION
 
     Total assets were $33.7 million at June 30, 1998 compared to $35.6 million
at December 31, 1997 and $22.9 million at December 31, 1996. Accounts receivable
increased by $2.0 million from 1996 to 1997, related to revenue growth, and
declined by $1.5 million in the first six months of 1998 due to improved
collections. Prepaid expenses, other current assets, accounts payable and
accrued liabilities all increased in relation to revenue growth.
 
     Investments represent the value ascribed to the exercised Tel-Save
warrants. The investment was liquidated for cash in the amount of $9.5 million
in June 1998 and was valued at December 31, 1997 at the amount of cash received.
At December 31, 1996, the investment was valued at $2.1 million using an
established valuation method.

     Property and equipment totaled $8.4 million at June 30, 1998, $7.0 million
at December 31, 1997, and $3.1 million at December 31, 1996. Capital
expenditures in the first six months of 1998 totalled $2.4 million, principally
related to the initial payments on switches to be deployed in the future. The
increase in property and equipment in 1997 relates primarily to approximately
$2.5 million in network additions and $1.9 million in computer equipment
additions, net of depreciation, both of which were financed through capital
leases entered into in 1997. Upon entering into the capital lease for the
network equipment, the Company repaid a term loan entered into in 1996. Property
and equipment is expected to grow significantly in 1998 and beyond, as the
Company adds additional switches and other equipment to its existing network.
 
     The Company owns its switches, located in Quincy, Massachusetts and Orlando
pursuant to a sale-leaseback arrangement with Chase Equipment Leasing, Inc. The
Company initially purchased the switches for an aggregate purchase price of $3.5
million and subsequently transferred title to the switches to its lender and
leased back the switches for five years. At the end of the lease term, the
Company has the option to purchase the switches for nominal consideration.
Payments under this lease arrangement totalled approximately $68,000 in 1997 and
require ongoing payments of approximately $68,000 per month.
 
     During 1997, additional capital was required to continue to expand the
Company's business. Additional liquidity was achieved by the issuance of notes
payable. In December, the Company issued a promissory note to Sprint for the
repayment of $4.6 million previously classified as accounts payable. The note's
maturity was September 1998. The note's remaining balance of $3.7 million was
repaid on May 1, 1998 from borrowings under the Existing Bank Credit Facility,
as described below. In December 1997, the Company borrowed $1.8 million pursuant
to the Stockholder Loans. Interest was paid monthly at the prevailing prime
rate. The Stockholder Loans, including accrued interest, were also repaid on May
1, 1998.
 
     In January 1996, NPI entered into a revolving credit agreement with Fleet,
which provided for borrowings of up to $7.0 million, including letters of
credit. This agreement was due to expire on May 31, 1998 and was refinanced in
May 1998, as described below. Borrowings under this line in excess of $5.0
million were subject to a formula-based arrangement based upon a percentage of
accounts receivable. Interest was payable monthly at Fleet's prime rate or
available LIBOR options. The maximum borrowings under the agreement in 1997 and
1996 were $5.0 million and $3.0 million, respectively. At December 31, 1996 the
loan balance was $2.0 million, with no outstanding letters of credit. At
December 31, 1997, the loan balance was $4.5 million, with letters of credit of
$120,000 outstanding.
 
     Cash provided by operating activities in the first six months of 1998
totaled $11.3 million, principally due to the $9.5 million received in late June
related to the Tel-Save warrant settlement. As a result, cash and cash
equivalents totaled $8.2 million at June 30, 1998. At June 30, 1998, the Company
had an outstanding LIBOR loan of $9.0 million in conjunction with the Existing
Bank Credit Facility, which was repaid in early July. At June 30, 1998,
outstanding letters of credit totaled $1.0 million.
 
     On May 1, 1998, NPI entered into the Existing Bank Credit Facility with
Fleet and terminated the previously existing agreement. The Existing Bank Credit
Facility has a term of three years and provides for borrowings of up to $23.0
million, subject to a formula-based arrangement based upon a percentage of
accounts receivable. Interest is payable monthly at Fleet's prime rate or, at
the Company's option, 1.75% above prevailing LIBOR rates. The Existing Bank
Credit Facility requires NPI to be in compliance with certain gross profit,
operating income, tangible net worth and other covenants. The Existing Bank
Credit Facility prohibits the payment by NPI of dividends to its stockholders
other than dividends in amounts necessary to pay income taxes and related tax
preparation costs of the Company's stockholders as a result of the Company's
status as an "S" corporation. Proceeds from this financing were used to repay
the Sprint Note and the Stockholder Loans. Availability under this line was
approximately $12.5 million on May 1, 1998. Proceeds from
 
                                       49
<PAGE>   55
 
borrowings under the New Revolving Credit Facility will be used to repay and
retire the Existing Bank Credit Facility. See "Description of Certain
Indebtedness".
 
     On August 14, 1998, the Company entered into a commitment letter with
Goldman Sachs Credit Partners L.P. for the New Revolving Credit Facility. The
New Revolving Credit Facility is a $60 million facility, concurrent with the
closing of which the Company expects to terminate the Existing Bank Credit
Facility. The New Revolving Credit Facility will have a term of 18 months. Under
the New Revolving Credit Facility, up to $60 million will be available, $30
million of which will be available based upon a percentage of accounts
receivable. Interest will be payable at one percent above the prime rate. The
New Revolving Credit Facility will require the Company to meet, among other
things, minimum levels of revenues, access lines in service and EBITDA. See
"Description of Certain Indebtedness -- New Revolving Credit Facility".
 
     On September 2, 1998, the Company paid a dividend in the aggregate amount
of $5.0 million. As a result, $2.5 million was distributed to each of Robert T.
Hale and Robert T. Hale, Jr. Following receipt of the dividend, Robert T. Hale,
Jr. reinvested $1.9 million in the Company (representing approximately the
distribution to Robert T. Hale, Jr., net of his estimated tax liability
resulting from such distribution), in the form of a long-term loan to the
Company; such loan, including interest, will be payable 10 days after the
redemption of the Series A Preferred Stock. The dividend distribution was funded
out of existing cash resources and the Existing Bank Credit Facility. See
"Description of Certain Indebtedness" and "Certain Transactions".
 
  EXPANSION OF SERVICES AND FUTURE CASH REQUIREMENTS
 
     The Company's strategic initiatives in 1998 include expanding both its
service offerings to include local exchange and Internet services and its
facilities-based infrastructure. These initiatives will require a substantial
amount of capital for, but not limited to, the installation of network switches
and related equipment, fiber, personnel additions and funding of operating
losses and working capital. The Company's strategic initiatives include the
deployment of additional long distance and international switches, the
deployment of local switches, the offering of new services such as local
exchange and Internet access services, the expansion of its sales force and
other personnel and significant investment in its information technology
systems.
 
     The Company believes that net proceeds from the Initial Offering, together
with cash flow generated from operations and borrowings available under the New
Revolving Credit Facility, will be sufficient to fund the Company's working
capital needs, planned capital expenditures and interest expense through at
least August 1999. The actual amount of capital expenditures and the timing of
such expenditures will depend on several factors, including equipment and fiber
availability, economic conditions, competition and regulatory developments. The
Company may also require additional financing, which may include public or
private debt and equity financings, to enter into strategic alliances, acquire
assets or businesses or make investments toward achieving its strategic
objectives. There can be no assurance, however, that the Company will be able to
raise sufficient funds or do so on acceptable terms. Failure to obtain such
financings could result in the delay or abandonment or the Company's development
and expansion plans. Furthermore, there can be no assurance that actual capital
needs and expenditures will not be significantly higher than the Company's
current estimates. See "Risk Factors -- Negative Cash Flow and Operating Losses"
and "-- Substantial Future Capital Requirements; Need for Additional Financing;
Substantial Leverage".
 
  IMPACT OF YEAR 2000
 
     Many computer systems experience problems handling dates beyond the year
1999. Therefore, some computer hardware and software will need to be modified
prior to the year 2000 in order to remain functional. The Company is completing
its preliminary assessment of both the internal readiness of its computer
systems and the compliance of its network and services sold to customers. The
Company expects to implement during 1998 the systems and programming changes
necessary to address year 2000 issues, and based on its evaluation, does not
believe that
 
                                       50
<PAGE>   56
 
the cost of such actions will have a material adverse effect on the Company's
results of operations or financial condition. There can be no assurance,
however, that there will not be a delay in, or increased costs associated with,
the implementation of such changes, and the Company's inability to implement
such changes could have a material adverse effect on future results of
operations. Furthermore, if the hardware or software comprising the Company's
network elements acquired from third party vendors or others on whose services
the Company depends or with whom the Company's systems interface, or the
software applications of other suppliers, are not year 2000 compliant, it could
affect the Company's systems, which could have a material adverse effect on the
Company's business, financial condition and results of operations. See "Risk
Factors -- Year 2000 Compliance".

THE COMPANY
 
  OVERVIEW
 
     Network Plus, founded in 1990, is a leading facilities-based integrated
communications provider ("ICP") offering switched long distance, data and
enhanced telecommunications services. The Company's customers consist primarily
of small and medium-sized businesses located in major markets in the
Northeastern and Southeastern regions of the United States. The Company also
provides international wholesale transport and termination services to major
domestic and international telecommunication carriers. In addition, the Company
intends to offer local services on a commercial basis in certain states
beginning in the third quarter of 1998. As of July 15, 1998, the Company served
over 34,000 customers representing in excess of 150,000 access lines and 30,000
toll-free numbers. All customers are directly invoiced by the Company on a
Network Plus bill. As of July 15, 1998, the Company had a 152-person sales force
located in eight regional offices, and in 1997 had total revenue of $98 million.
 
     The Company owns network components where economically advantageous and
leases components where more capital-efficient. The Company has switches in
Quincy, Massachusetts and Orlando, and intends to add switches throughout the
second half of 1998 and continuing through 1999 in Atlanta, Chicago, Los Angeles
and New York City as well as multiple local traffic switches in the Northeastern
and Southeastern regions of United States. In May 1998, over 60% of the
Company's revenue was generated by customer traffic carried on its network, and
the Company expects this percentage to increase as the Company further expands
its facilities-based infrastructure. The Company recently entered into two
20-year indefeasible right-of-use ("IRU") agreements pursuant to which it
acquired 625 route miles of dark fiber (1,830 digital fiber miles), that, when
fully deployed and activated, will form a redundant fiber ring connecting major
markets throughout New England and the New York metropolitan area and provide
the Company with significant transmission capacity.
 
     The Company believes that, because of its large and highly focused sales
force and superior customer support, the Company will be successful in rapidly
acquiring new customers, continuing to migrate "off-net" long distance customers
to its network, cross-selling local services to its existing long distance
customers and maintaining a high rate of customer retention. The compounded
annual growth rate for the number of customers from year end 1994 to year end
1997 was 68%.
 
     The Company's business strategy is to leverage its eight-year operating
history, existing customer base and substantial in-region experience to (i) be a
one-stop ICP offering a comprehensive array of bundled voice and data solutions,
(ii) acquire and retain market share through its direct sales force and focused
customer service, (iii) enhance its facilities-based infrastructure where
economically advantageous and continue the migration of traffic to its network,
(iv) build and retain market share through advanced technologies and an advanced
operational support system, (v) target the underserved market of small and
medium-sized businesses, with a focus on the Northeastern and Southeastern
regions of the United States, (vi) increase international wholesale sales and
(vii) expand through strategic acquisitions and alliances.
 
  NETWORK INFRASTRUCTURE
 
     The Company pursues a capital-efficient network deployment strategy that
involves owning switches and acquiring or leasing fiber optic transmission
facilities on an incremental basis to satisfy customer demand. The Company
believes that its switch-based, lease-or-acquire transport strategy provides
significant competitive advantages. By owning network components, the Company is
able to generate higher operating margins and maintain greater control over its
network operations. The Company structures its network expansion decisions in a
manner designed to (i) reduce up-front capital expenditures required to enter
new markets, (ii) avoid the risk of stranded investment in under-utilized fiber
networks and (iii) enter markets and generate revenue and positive cash flow
 
                                       52
<PAGE>   58
 
more rapidly than if the Company first constructed its own facilities. Where
market penetration does not economically justify the deployment of its own
network, the Company utilizes the networks of alternative carriers.
 
     In addition to its 625 route miles of dark fiber, Network Plus currently
owns and maintains (i) a Northern Telecom, Inc. ("Nortel") international gateway
and interexchange switch in Quincy, Massachusetts, and (ii) a Nortel
interexchange switch in Orlando. The Company is currently deploying both a
Nortel international gateway and interchange switch in Los Angeles and a Nortel
interexchange switch in Chicago. The Company has a Network Operations Center in
Quincy, Massachusetts, which monitors the Company's entire network from a
central location, increasing the security, reliability and efficiency of the
Company's operations. The Company is also planning the deployment of local
switching facilities throughout the Northeastern and Southeastern regions of the
United States. The Company intends to further expand its network in geographic
areas where customer concentrations or traffic patterns make expansion
economically advantageous.
 
  SERVICES
 
     Network Plus offers retail telecommunications services primarily to small
and medium-sized businesses. Retail offerings currently include long distance
and toll-free services (both with and without Advanced Intelligent Network
("AIN") features), multiple access options, calling and debit card, paging,
data, and custom management control features. The Company plans to add local
exchange services, Internet services and additional AIN features in the latter
part of 1998 and into 1999. The Company also offers international wholesale
services primarily to interexchange carriers ("IXCs") and international
telecommunications carriers. In May 1998, retail and wholesale offerings
accounted for approximately 78% and 22%, respectively, of the Company's total
revenue.
 
  LARGE AND GROWING SALES FORCE
 
     As of July 15, 1998, Network Plus had a 152-member, highly focused sales
force consisting of a 140-person direct retail sales force, a six-person
international wholesale sales force and a six-person agent and reseller sales
force. The Company's sales approach is to build long-term relationships with its
customers, with the intent of becoming the single-source provider of their
telecommunications services. The Company trains its sales force in-house with a
customer-focused program that promotes increased sales through both customer
attraction and customer retention. All members of the sales force are given
incentives through a commission structure under which commissions are paid on an
ongoing basis for as long as the customer continues to purchase services from
the Company. This "lifetime residual" is intended to motivate the sales force to
remain actively involved with customers and participate in the customer
retention and support process. The Company believes that this customer
support-focused commission structure and in-house training are unique in the
industry and provide the Company with a competitive advantage in attracting and
retaining customers. The sales force currently is located in eight offices and,
by year end 1999, the Company intends to open additional sales offices and
expand its sales force to approximately 400 members. The Company expects that it
will continue to utilize a modular sales force structure and that existing
employees with substantial sales experience will manage new sales offices,
ensuring a continuation of the Company's customer-focused culture. The Company's
sales force director, regional sales directors, branch managers and team leaders
have an average employment tenure of over five years with the Company.
 
  MANAGEMENT
 
     Robert T. Hale, Jr., the Company's President, Chief Executive Officer,
Director and co-founder, has more than 10 years of experience in the
telecommunications industry. Robert T. Hale, the Company's Chairman and
co-founder, has more than eight years of experience in the telecommunications
industry, is a Director and former Chairman of the 600-member Telecommunications
Reseller Association ("TRA") and has been Chairman of the TRA's Underlying
Carrier Committee since 1992. Network Plus's eight-member Executive Officer
group has an average employment
 
                                       53
<PAGE>   59
 
tenure of more than three years with the Company and an average of over 11 years
of experience in the telecommunications industry. The Company believes that the
quality, tenure and teamwork of its management team will be critical factors in
the implementation of its expansion strategy.
 
MARKET OPPORTUNITY
 
     As a result of the Telecommunications Act of 1996 (the "Telecommunications
Act") and other federal, state and international initiatives, numerous
telecommunications markets have been opened to competition. In addition, the
increasing globalization of the world economy, along with an increased reliance
on data transmission and Internet access, has expanded the traditional
telecommunications markets. After completing its planned expansion, the Company
expects to have 18 sales offices in 12 states in the Northeastern and
Southeastern regions of the United States. According to industry data, in 1997
there were approximately 8.7 million business lines in the Company's markets in
the Northeastern region (the New England states, New York and New Jersey) and
4.8 million business lines in the Company's markets in the Southeastern region
(Florida, Georgia, North Carolina, South Carolina and Tennessee). The Company
anticipates significant demand for its services, based on its belief that small
and medium-sized businesses are not aggressively targeted by large providers and
are underserved with respect to customer service and support.
 
BUSINESS STRATEGY
 
     Network Plus intends to undertake an aggressive growth strategy to meet its
goal of becoming the ICP of choice providing one-stop telecommunications
solutions to customers in its markets. The Company's future success will depend
upon its ability to implement this strategy. Unlike many emerging
telecommunications companies, the Company has a proven eight-year operating
history. The Company believes that the collective talent and telephony
experience of its management and employee base provide a competitive advantage
and position the Company to effectively implement its growth strategy, which
includes the following:
 
  PROVIDE INTEGRATED TELECOMMUNICATIONS SERVICES
 
     A key element in the Company's growth will be the implementation of a
marketing and operating plan that emphasizes an integrated voice and data
telecommunications solution. To a large extent, customers the Company expects to
target have not previously had the opportunity to purchase bundled services from
a single provider. The Company believes that these customers will prefer one
source for all of their telecommunications requirements, including products,
billing and service. The Company intends to be the single source of, and provide
a consolidated bill for, integrated local, long distance and other
telecommunications services, in addition to providing a single point of contact
for customer service, product inquiries, repairs and billing questions. The
Company believes that one-stop integrated communications services will enable it
to further penetrate its existing markets, expand its customer base, capture a
larger portion of its customers' total expenditures on telecommunication
services and increase customer retention.
 
  EXPAND SALES FORCE AND FOCUS ON CUSTOMER SERVICE
 
     The Company intends to significantly expand its sales force to both acquire
and support a growing customer base. The Company's sales force consisted, as of
July 15, 1998, of 152 members and is expected to grow to approximately 400 by
year end 1999. To support its customer base, the Company provides customer
service 24 hours per day, 365 days per year, and estimates that its customer
service representatives currently have an average response time for answering
incoming calls of under 15 seconds. In addition, the commission structure of the
Company's direct retail sales force is designed to promote a high level of
ongoing customer care and to assure that the sales staff remains actively
involved in the customer service process. Similarly, the compensation of
customer support personnel is designed to promote a high level of ongoing
customer care and retention. The
                                       54
<PAGE>   60
 
Company believes that its sales and customer service processes have resulted in
a customer retention rate that is higher than that of many competitors and
differentiate the Company as a customer-focused ICP, giving it a competitive
advantage.
 
  ENHANCE FACILITIES-BASED INFRASTRUCTURE
 
     The Company intends to continue migration of customer traffic to its own
network and to cross-sell new services, such as local service, to its customers.
Expansion of the Company's facilities-based infrastructure with fiber and
switches will increase the proportion of telecommunications traffic that is
originated or terminated on its network, which the Company believes will result
in higher long-term operating margins and greater control over its network
operations. The Company's approach to network design is structured to minimize
the capital investment necessary to provide service, avoid spending capital
where not economically justifiable, better match the commitment of capital to
the onset of revenue-generating activities and generate cash flow more quickly.
Throughout the second half of 1998 and continuing through 1999, the Company
intends to enhance its facilities by purchasing and installing (i) Nortel
interexchange switches in Chicago and New York, (ii) a Nortel interexchange and
local switch in Atlanta, (iii) a Nortel interexchange and international gateway
switch in Los Angeles and (iv) multiple Nortel local traffic switches throughout
the Northeastern and Southeastern regions of United States. In addition, the
Company intends to begin offering high-quality dedicated and dial-up Internet
services.
 
  CONTINUE INVESTING IN ADVANCED TECHNOLOGIES AND AN ADVANCED OPERATIONAL
SUPPORT SYSTEM
 
     Network Plus expects to continue to invest in advanced technologies that
provide strategic advantages by integrating the Company's network facilities
with its operational support system ("OSS") to enhance service response time.
The Company intends to deploy Nortel's Service Builder throughout its network
infrastructure, which will elevate the Company's network from a state-of-the-art
SS7 network to a next-generation intelligent network. Service Builder will also
permit the rapid deployment of "designer" intelligent network products and
services such as nationwide "follow me" numbers and Time-of-Day Routing, as well
as accelerate the Company's compliance with legally mandated services such as
local number portability ("LNP"). To support integrated provisioning and
customer care for all products and services, the Company is developing an open
scalable client/server Oracle-based platform that is expected to better
integrate its operations, both geographically and among departments. The Company
believes that these technologies will provide a long-term competitive advantage
by allowing a more rapid implementation of switched local services in its
markets, shortening the time between the receipt of a customer order and the
generation of revenue and enabling a higher level of focused customer care.
 
  TARGET UNDERSERVED MARKETS WITH A SUPER-REGIONAL FOCUS
 
     Network Plus intends to continue targeting small and medium-sized
businesses in the Northeastern and Southeastern regions of the United States,
its primary service areas, while expanding into other markets in the
Mid-Atlantic region, Illinois and California. The Company will seek to be among
the first to market integrated communications services in many of its markets.
The Company believes that the Northeastern and Southeastern regions are
particularly attractive due to a number of factors, including (i) the population
density in the Northeast; (ii) a large number of rapidly growing metropolitan
clusters in the Southeast, such as Atlanta, Miami/Fort Lauderdale and Orlando;
and (iii) the relatively small number of significant competitors to the
incumbent local exchange carriers ("ILECs"). In addition, the Company believes
that small and medium-sized businesses have been underserved by large
competitors with respect to customer service and support, and that its emphasis
on customer service, support and satisfaction provides it with a distinct
competitive advantage. The Company also believes that ILECs, such as regional
Bell operating companies ("RBOCs"), and the largest national carriers primarily
concentrate their sales
 
                                       55
<PAGE>   61
 
and marketing efforts on residential and large business customers and that the
market for small and medium-sized businesses is generally less competitive.
 
  INCREASE INTERNATIONAL WHOLESALE SALES
 
     The Company intends to continue targeting the sale of both international
and domestic termination and transport services to wholesale customers such as
large IXCs and international telecommunications carriers. The Company believes
that the international market represents a growing opportunity as a result of
the rapidly increasing globalization of the world economy. The Company's
international department is focused on the development of offshore
telecommunications relationships that provide the Company with lower
international termination costs as well as greater price stability than can be
obtained from U.S.-based carriers. These relationships are being leveraged by
the Company to obtain revenue through the domestic termination of offshore-
originated traffic, in addition to their primary role of enabling the Company to
offer international termination to its customers. The Company has already made
significant investments in its international network capabilities, including a
Nortel international gateway switch in Quincy, Massachusetts and lease and
indefeasible right of use ("IRU") arrangements for international submarine cable
capacity in TAT 12/13 and Americas I in the Atlantic Ocean and TPC-5 in the
Pacific Ocean, as well as various subsidiary feeder cable systems. In addition
to increasing revenue, the Company expects that its strategy of selling
international wholesale services will lower the cost of carrying all its
international traffic and result in more attractive service offerings in its
core retail markets. As of June 1, 1998, the Company provided its international
wholesale services to 13 domestic and foreign telecommunications carriers, and
in May 1998 such services accounted for 22% of the Company's revenue.
 
  EXPAND THROUGH STRATEGIC ACQUISITIONS AND ALLIANCES
 
     As part of its expansion strategy, the Company plans to consider
acquisitions, joint ventures and strategic alliances in telecommunications,
Internet access and other related service areas. The Company believes that
acquisitions of, and joint ventures and other strategic alliances with, related
or complementary businesses may enable it to more rapidly expand by adding new
customers, new services, additional customer service and technical support
capabilities, and additional cash flow. The acquisitions could be funded by
cash, bank financing or the issuance of debt or equity securities. The Company
is evaluating and often engages in discussions regarding various acquisition
opportunities but is not currently a party to any agreement for a material
acquisition.
 
SERVICE OFFERINGS
 
     The Company offers retail telecommunications services primarily to small
and medium-sized businesses. The Company's retail service offerings currently
include long distance and toll-free services (both with and without AIN),
multiple access options, calling and debit card, paging, data, and custom
management control features. The Company plans to add local exchange service,
Internet services and additional AIN features in the latter part of 1998 and
into 1999. The Company also offers wholesale international and domestic
termination and transport services primarily to major domestic and international
telecommunications carriers.
 
  CURRENT SERVICES
 
     Retail Services.  As of July 15, 1998, the Company provided retail
telecommunications services to over 34,000 customers, primarily small and
medium-sized businesses located in the Northeastern and Southeastern regions of
the United States. Retail services are sold through the Company's direct retail
sales force and, to a lesser extent, through resellers and independent marketing
 
                                       56

     - LOCAL SERVICES:  The Company is currently providing local services on a
       test basis in Massachusetts, and the Company intends to begin offering
       such services in certain of its service areas on a commercial basis by
       the end of 1998. See "Planned Services" below.
 
     International Wholesale Services.  The Company offers international
wholesale termination and transport services primarily to major domestic and
international telecommunications carriers. The Company believes its
international wholesale service offering is a strategic element in its overall
plan to expand its network and to generate and retain customer traffic. The
Company intends to build on its relationships with large domestic and
international carriers to purchase increased capacity and to otherwise support
its international service offerings. In addition, the Company expects that its
 
                                       57
<PAGE>   63
 
provision of comprehensive international services will lower the cost of
carrying international traffic and result in more attractive service offerings
in its core markets.
 
  PLANNED SERVICES
 
     Local Services.  The Company intends to begin offering local service on a
commercial basis by the end of 1998 in Massachusetts, New Hampshire, Rhode
Island and Vermont and in 1999 in Connecticut, New York, New Jersey, Georgia,
Tennessee and Florida. The Company intends to deploy local switches, enter into
resale agreements and enter into interconnection agreements in target market
areas as market conditions warrant. As part of its plan to offer local exchange
services, the Company (i) has obtained authority to provide local service in
Massachusetts, New Hampshire and Rhode Island and is currently in the process of
obtaining CLEC status in additional New England States, New York, New Jersey,
Georgia, Florida, Pennsylvania and Tennessee, and (ii) has entered into an
interconnection agreement with Bell Atlantic for Massachusetts and has commenced
the negotiation of interconnection agreements with Bell Atlantic, Bell South,
GTE, Sprint and SNET for the purpose of gaining access to the unbundled network
elements necessary to offer facilities-based local exchange services in other
states. See "Risk Factors -- Lack of Experience Offering Local and Other
Telecommunications Services", "Risk Factors -- Reliance on Leased Transport
Facilities and IRUs", "Risk Factors -- Lack of Interconnection and Peering
Agreements", "Risk Factors -- The Telecommunications Act and Other Regulation"
and "Government Regulation".
 
     Internet Services.  In 1999, the Company intends to begin offering
customers Internet access, including high quality dedicated and dial-up Internet
connection and IP transport.
 
     Advanced Local Services.  In connection with its local exchange service
offering, the Company intends to offer value added local exchange services on
both a resale basis (where such services are made available for resale) and on a
switched-facilities basis, including the following: ISDN, Centrex, Trunk Line
Service, Voice Mail (unbundled network element only), Hunt Sequencing, Three Way
Calling, Call Forwarding, Call Waiting, Speed Dial, Voice Dialing, All Call
Blocking, Selective Blocking, Foreign Exchange, Call Trace and Caller ID.
 
SALES AND MARKETING
 
  OVERVIEW
 
     The Company's sales force seeks to provide its existing and potential
customers with a comprehensive array of telecommunications services customized
for the increasingly convergent voice and data marketplace. The Company's
customers consist primarily of small and medium-sized businesses that have
telecommunications expenditures of less than $10,000 per month. The Company
believes that RBOCs and large long distance carriers historically have not
concentrated their sales and marketing efforts on this business segment, which
the Company believes represents a significant portion of the telecommunications
market. Through its sales force and its eight-year operating history, the
Company believes it has established itself as a recognized provider of high-
quality, competitively priced long distance services, with a reputation for
responsive customer care.
 
     The Company's sales and marketing approach is to build long-term business
relationships with its customers, with the intent of becoming the single source
provider of all their telecommunications services. The Company trains its sales
force in house with a customer-focused program that promotes increased sales
through both customer attraction and customer retention. In addition, all
members of the sales force are given incentives through a commission structure
under which commissions are paid on an ongoing basis for as long as a customer
continues to purchase services from the Company. This "lifetime residual" is
intended to motivate the sales force to remain actively involved with customers
and participate in the customer retention and support process. The Company
believes that its customer support-focused commission structure and in-house
training
 
                                       58
<PAGE>   64
 
are unique in the industry and provide the Company with a competitive advantage
in attracting and retaining customers.
 
     Members of the Company's sales force are assigned to one of the following
sales groups: (i) the direct retail sales force, which markets the Company's
retail telecommunications services directly to end users; (ii) the reseller and
independent agent sales force, which markets the Company's telecommunications
services to resellers, independent marketing representatives, associations and
affinity groups; and (iii) the international wholesale sales force, which sells
the Company's international telecommunications services on a wholesale basis to
major domestic and international telecommunications carriers.
 
  SALES CHANNELS
 
     DIRECT RETAIL SALES.  The Company's direct retail sales force markets the
Company's retail telecommunications services directly to end users. As of July
15, 1998 the Company employed 140 direct sales representatives working in eight
regional offices. By year end 1999, the Company intends to open additional sales
offices. This anticipated expansion will result in a sales force with
approximately 400 direct retail sales personnel located in 18 offices throughout
the Northeastern and Southeastern regions of the United States. See "Risk
Factors -- Management of Rapid Growth".
 
     The sales force is led by Robert T. Hale, Jr., who has over 10 years of
telecommunications sales experience. The direct sales force is divided into two
regions: (i) a Northeastern region, headed by a regional sales director with
seven years of telecommunications sales experience with the Company; and (ii) a
Southeastern region, headed by a regional sales director with seven years of
telecommunications sales experience with the Company. Each of the Company's
existing eight sales offices is headed by a branch manager with from four to
seven years of direct telecommunications sales experience with the Company. Each
sales office is further sub-divided into smaller sales teams, each of which is
headed by a team leader who directly oversees the day-to-day sales activities of
his or her team and acts as a mentor to its members. Teams generally consist of
eight to 10 sales representatives.
 
     The Company's direct retail sales force has a proven management structure
based on a "growth from within" philosophy. As the Company opens a sales office
in a new geographic area, it identifies a branch manager and team leader to head
the new office. New branch managers are typically chosen from among the
Company's experienced team leaders, and team leaders are typically chosen from
among the Company's experienced sales representatives. Because these new
positions represent promotion opportunities, the Company has been successful in
opening new offices with management teams having significant Network Plus work
experience. As branch managers and team leaders relocate to offices in new
geographic areas, they immediately hire new sales representatives from the area.
All new sales representatives are required to receive formal in-house training,
where they are expected to gain a thorough knowledge of the Company's services
and the telecommunications industry. After formal training, sales
representatives are permitted to pursue customers but are required to
participate in a continuing mentoring program. The Company believes this
philosophy is a competitive advantage in the attraction and long-term retention
of sales personnel.
 
     The Company also telemarkets its long distance services, primarily to small
businesses and residential users. Telemarketing activities are conducted by 16
employees located at the Company's telemarketing center in Largo, Florida, which
was established in the fourth quarter of 1997.

</TABLE>
 
     RESELLER AND INDEPENDENT AGENT SALES.  The Company's reseller and
independent agent sales force markets the Company's telecommunications services
to various resellers, independent marketing representatives, associations and
affinity groups. The focus of the reseller and independent agent sales force is
to locate established, high-quality organizations with extensive distribution
channels in order to market the Company's telecommunications services to both a
broader geographic range of potential customers and a greater number of
potential customers than could be reached by the direct retail sales force.
 
     The Company sells its services on a wholesale basis to resellers, which in
turn sell such services at retail to their customers. The Company generally
sells its services to independent marketing representatives, associations and
affinity groups on a retail basis. Use of independent marketing representatives
allows the Company to reduce its marketing and other overhead costs. As
compensation for their services, independent marketing representatives generally
receive a commission on their sales. The Company employs stringent selection
criteria and attempts to carefully monitor and control the activities of its
resellers and independent marketing representatives to ensure compliance with
laws, industry standards, and corporate policies. The Company believes that the
number of complaints it has received regarding the methods and practices of its
agents is negligible in comparison with that of many other telecommunications
companies.
 
     The Company's reseller and independent agent sales force is split into
three regions: (i) a Northeastern region, headed by a regional sales director
with seven years of telecommunications sales experience with the Company; (ii) a
Southeastern region, headed by a regional sales director with three years of
telecommunications sales experience with the Company; and (iii) a West Coast
region, headed by a regional sales director with eight years of
telecommunications sales experience with the Company. The Company commenced
sales through resellers and independent marketing representatives in 1996, and
the Company currently has six salespeople dedicated to this market segment. In
May 1998, sales through the Company's reseller and independent agent sales force
accounted for 13% of the Company's revenue.
 
                                       60

     INTERNATIONAL WHOLESALE SALES.  The Company's international wholesale sales
force markets the Company's international telecommunications services to both
international and domestic telecommunications providers. The international
wholesale sales force is focused on developing customer and vendor relationships
with the top tier IXCs as well as RBOCs and selected financially stable second
tier IXCs. In May 1998, international wholesale sales accounted for
approximately 22% of the Company's revenue.
 
     The Company's international wholesale sales force is headed by the Vice
President and General Manager of International Services, who has over 16 years
of experience in international telecommunications sales, service and networks.
In addition, this sales group includes three specialized international wholesale
sales representatives, each of whom has over four years of telecommunications
sales experience with the Company. As of July 15, 1998, the Company had six
sales people in its international wholesale sales force, and expects that number
to increase to 15 by year end 1998 and to 21 by year end 1999.
 
  SALES FORCE COMPENSATION
 
     All sales persons, regardless of sales group, are compensated with both a
salary and a residual commission structure based on each customer's continued
use of the Company's services. The compensation of members of the Company's
sales force is therefore increasingly reliant over time on the retention of
existing customers. It is the Company's belief that this "lifetime residual"
motivates each sales person to remain actively involved with customers and
participate in the customer support process. The Company believes this approach
to commissions is unique in the industry and provides the Company with
competitive advantages including (i) enhanced relationships, which increase
cross-selling opportunities; (ii) reduced customer service and support costs;
and (iii) increased customer retention.
 
  SIMPLICITY PRICING
 
     The Company utilizes a flat-rate per-minute pricing structure for long
distance and certain other services, which the Company refers to as Simplicity
Pricing. The Company believes this simplified pricing structure assists in the
sales process and gives the Company a competitive advantage over larger long
distance competitors which historically have used complex pricing structures
featuring either distance-sensitive calling charges or myriad base rates and
discounting schemes. The Company strives to deliver this Simplicity Pricing on a
timely invoice in a format that is user-friendly.
 
  MARKETING AND ADVERTISING
 
     Historically, because the Company has been successful in relying upon its
sales force to obtain additional customers and increased name recognition, the
Company has refrained from undertaking significant advertising efforts. The
Company is actively involved in numerous charitable and community events, which
the Company believes increase recognition of the Company in particular
geographic regions. The Company has no immediate plans to allocate significant
resources to direct advertising efforts.
 
CUSTOMER BASE
 
  RETAIL CUSTOMERS
 
     As of July 15, 1998, the Company had over 34,000 retail customers, which
the Company internally segments by monthly revenue into (i) a National Account
segment (over $1,000 of usage per month), (ii) a Major Account segment (between
$250 and $1,000 of usage per month) and
 
                                       61
<PAGE>   67
 
(iii) a Small Business/Residential Customer Account segment (under $250 of usage
per month). This segmentation is designed to ensure that those customers
generating higher monthly revenues experience a higher level of proactive
customer care. As of July 15, 1998 the National Segment included over 1,900
customers generating approximately 56% of the Company's revenue for June 1998,
the Major Account Segment included over 4,600 customers generating approximately
25% of the Company's revenue, and the Small Business/Residential Account Segment
included over 26,000 customers generating approximately 19% of the Company's
revenue.
 
  INTERNATIONAL WHOLESALE CUSTOMERS
 
     As of June 1, 1998, the Company provided wholesale international
telecommunications services to 13 national and international telecommunications
carriers. International wholesale telecommunications services include
international transport and termination services for domestic carriers and
domestic transport and termination services for international carriers. During
May 1998, wholesale telecommunications services accounted for 22% of the
Company's revenue.
 
     The Company strives to establish close working relationships with its
wholesale international customers. Once the Company interconnects with a carrier
customer, the carrier may utilize the Company on an as-needed basis, depending
upon the pricing offered by the Company and its competitors, as well as
capacity. The Company has been tested and approved as an authorized carrier for,
and included in the routing tables of, all of its long distance and
international carrier customers.
 
     During the years ended December 31, 1997, 1996 and 1995, the Company had
one retail customer that accounted for approximately 10% of the Company's
revenue. In the first six months of 1998, the Company had one wholesale customer
that accounted for approximately 11% of the Company's revenue. The Company does
not expect that any one customer will account for more than 10% of its revenue
during the full year 1998.
 
CUSTOMER SUPPORT
 
     The Company maintains an emphasis on customer care to differentiate itself
from its competitors, especially larger providers, and to increase customer
retention. The Company provides 24-hours-per-day, 365-days-per-year customer
support primarily through its customer service department in Quincy,
Massachusetts. At the Company's customer support center, customers' calls are
answered by experienced customer care representatives, many of whom are
cross-trained in the provisioning process. Support staff are trained to work
with the Company's sales force and be proactive in the customer support process.
In addition to calls made by the Company's sales department, members of the
customer support staff proactively seek to contact national customers monthly
and major customers quarterly to help ensure a high level of satisfaction with
the Company. The Company's customer support team is organized to help ensure
that the most knowledgeable personnel handle support requests from the largest
customers.
 
     The customer support staff utilizes a sophisticated management information
system to access all customer information including contact information,
customer rates, trouble ticket systems, accounts receivable and billing history.
In addition, the Company utilizes a provisioning system that maintains a
complete history of a customer's provisioning and allows real-time access to
information concerning each transaction with the LEC or underlying carrier. The
Company believes that its customer support and provisioning systems enhance the
Company's customer retention rate.
 
     The Company monitors and measures the quality and timeliness of customer
interaction through quality assurance procedures. Pick-up times for incoming
calls, lengths of calls and other support information is automatically monitored
by the Company's automated call distribution system ("ACD"). The Company's ACD
also prioritizes incoming support requests, assuring that the Company's largest
customers receive support in the most expedient manner.
 
                                       62
<PAGE>   68
 
     The Company's customer support department consists of five discrete areas:
National Accounts Management, Major Accounts Management, Small Business and
Residential Accounts Management, Repair Desk, and Save and Win-Back Team. The
Company's Customer Service Department is managed by the Director of Customer
Service, who has six years of sales and customer service experience with the
Company. Additional members of the Customer Service Management team include (i)
the National Accounts Manager, who has five years of sales and customer service
experience with the Company; (ii) the Major Accounts Manager, who has four years
of sales and customer service experience with the Company; (iii) the Small
Business and Residential Accounts Manager, who has two years of sales and
customer service experience with the Company; (iv) the Repair Desk team members,
each of whom has a minimum of two years of customer service experience with the
Company; and (v) the Save and Win-Back team members, each of whom has a minimum
of four years of sales and customer service experience with the Company.
 
     Customer support agents are required to complete an intensive formal
in-house training program before interacting with customers and are required to
participate in a continuing mentor program. Customer support personnel are
expected to have a thorough knowledge of the Company's services and to emphasize
customer satisfaction. The compensation of support personnel is in part
dependent upon the retention rate of their respective accounts. The Company has
an established career path for its agents, who over time gain responsibility for
larger customers, as well as management responsibilities.
 
     The Company's customer support department currently receives approximately
800 support calls per day. The Company estimates that the average incoming call
is answered by a support specialist in under 15 seconds, which the Company
believes compares favorably to many competitors. The Company also utilizes four
billing cycles per month, which helps ensure that customer service calls will be
staggered throughout each month. If the Company is successful in entering the
local service market, the Company believes that its level of customer service
will provide it with a competitive advantage over existing local service
providers. As of July 15, 1998, the Company employed 32 people in customer
support. The Company anticipates that it will continue to hire additional
customer support personnel as the size of its customer base increases. See "Risk
Factors -- Dependence on Billing, Customer Service and Information Systems".
 
NETWORK
 
     The Company pursues a capital-efficient network deployment strategy that
involves owning switches while acquiring or leasing fiber optic transmission
facilities on an incremental basis to satisfy customer demand. The Company's
strategy has been to build a geographic concentration of revenue-producing
customers through the resale of telecommunications services before building,
acquiring or extending its own network to serve that concentration of customers.
As network economics justify the deployment of switching or transport capacity,
the Company expands its network and migrates customers to its network. The
Company believes that this strategy allows the Company to penetrate new markets
through its resale solution without incurring the risks associated with
speculative deployment of network elements and to focus its capital expenditures
in those geographic areas and markets where network expansion will result in
higher long-term operating margins.
 
  CURRENT NETWORK
 
     SWITCHES.  Currently, the Company operates an advanced telecommunications
network that includes two Nortel switches. Network Plus believes that the Nortel
DMS family of switches is the most reliable and advanced in the
telecommunications marketplace. The switch located in Quincy, Massachusetts is a
DMS 250/300 digital switch that combines on a single platform the DMS 250's
interexchange switching capabilities and the DMS 300's international gateway
capabilities. The
 
                                       63
<PAGE>   69
 
switch located in Orlando, Florida is a Nortel DMS 250. The Company's switches
are owned pursuant to capital lease arrangements.
 
     During May 1998, the Company carried approximately 24.9 million minutes, or
approximately 47% of its total minutes, on its own network. The Company
anticipates that this percentage will increase as it further expands its
facilities-based infrastructure. The Company believes that increasing the
traffic carried on its own network will increase long-term operating margins and
give the Company greater control over its network operations.
 
     FIBER AND TRANSPORT.  The Company recently entered into two 20-year
indefeasible right-of-use ("IRU") agreements with two separate carriers pursuant
to which it acquired 625 route miles of dark fiber (1,830 digital fiber miles).
When the fiber is fully deployed and activated, it will form a redundant fiber
ring connecting major markets throughout New England and the New York
metropolitan area, providing the Company with significant transmission capacity.
The first IRU agreement is for 293 fiber route miles containing four dark Lucent
TrueWave optical fibers. Markets connected by this segment include New York
City, White Plains, Stamford, New Haven, New London, Providence and Boston. The
second IRU agreement is for 332 fiber route miles containing two dark Lucent
TrueWave optical fibers. Markets connected by this segment include Boston,
Nashua, Springfield, Hartford, White Plains and New York City. The Company will
install and control all electronics and optronics, including wave division
multiplexing technologies.
 
     Where the Company has not acquired fiber, it leases long-haul network
transport capacity from major facilities-based carriers and local access from
the ILECs in their respective territories. The Company also uses competitive
access provider ("CAP") or CLEC facilities where available and economically
justified. To ensure seamless off-net termination and origination, the Company
also utilizes interconnection agreements with major carriers. See "Risk
Factors -- Reliance on Leased Transport Facilities and IRUs".
 
     INTERNATIONAL.  The Company is interconnected with a number of U.S. and
foreign wholesale international carriers through the Quincy, Massachusetts DMS
250/300 switch. The purpose of connecting to a variety of carriers is to provide
state-of-the-art least-cost routing and network reliability. These
interconnected international carriers are also a source of wholesale
international traffic and revenue. To further support its international
interconnections the Company has entered into leases for international submarine
cable facilities in TAT-12/13, RIOJA in the Atlantic Ocean and TPC-5 in the
Pacific Ocean. In addition, in December 1997 the Company purchased indefeasible
rights of use capacity in the Americas I cable system. These arrangements
support existing and planned interconnections with telephone operating companies
in foreign countries.
 
     OTHER FEATURES.  The Company is also interconnected with two Signaling
Transfer Points in Waterbury, Connecticut and New Haven, Connecticut to provide
SS7 common-channel signaling throughout its network. The SS7 signaling system
reduces connect time delays, thereby enhancing overall network efficiencies.
Additionally, SS7 will permit the anticipated expansion of AIN capabilities
throughout the Company's network. The Company's uniform and advanced switching
platform will enable it to (i) deploy features and functions quickly throughout
its entire network, (ii) expand switch capacity in a cost-effective manner,
(iii) lower maintenance costs through reduced training and spare parts
requirements and (iv) achieve direct connectivity to cellular and personal
communication system applications in the future.
 
     SECURITY AND RELIABILITY.  The Company has a Network Operations Center in
Quincy, Massachusetts, which monitors the Company's entire network from a
central location, increasing the security, reliability and efficiency of the
Company's operations. Centralized electronic monitoring and control of the
Company's network allows the Company to avoid duplication of this function in
each region. This consolidated operations center also helps reduce the Company's
per-customer monitoring and customer service costs. In addition, the Company's
network employs an "authorized access" architecture. Unlike many
telecommunications companies, which allow universal access to
 
                                       64
<PAGE>   70
 
their network, the Company utilizes an automatic number identification ("ANI")
security screening architecture that ensures only the ANIs of those users who
have subscribed to the Company's services and have satisfied the Company's
credit and provisioning criteria are allowed access to the network. The Company
believes that this architecture provides the Company a competitive advantage
through its ability to better control bad debt and fraud in a manner that is
invisible and nonintrusive to the customer. Additionally, this architecture
allows the Company to better manage network capacity, as unauthorized and
unplanned users cannot access the network. See "Risk Factors -- Dependence Upon
Network Infrastructure; Risk of System Failure; Security Risks".
 
  ANTICIPATED NETWORK EXPANSION
 
     As part of its growth strategy, the Company plans to undertake a
significant network expansion through the deployment of additional switching and
transport infrastructure to support its goal of continuing migration of its
customers' traffic to its own network. Expansion of the Company's
facilities-based infrastructure with international gateway, long distance and
local switches will increase the proportion of communications traffic that is
originated or terminated on its network, which the Company believes will result
in higher long-term operating margins and greater control over its network
operations. The Company structures its network expansion decisions in a manner
designed to (i) reduce up-front capital expenditures required to enter new
markets, (ii) avoid the risk of "stranded" investment in under-utilized fiber
networks and (iii) enter markets and generate revenue and positive cash flow
more rapidly than if the Company first constructed its own facilities. The
Company intends to further expand its network in geographic areas where customer
concentrations and traffic patterns make expansion economically justifiable. See
"Risk Factors -- Substantial Future Capital Requirements; Need for Additional
Financing; Substantial Leverage".
 
     The Company also plans to expand its business by offering a full range of
local services in the geographic regions where the Company already has an
established customer base. The Company intends to offer local services by (i)
entering into interconnection agreements with ILECs; (ii) deploying its
facilities-based infrastructure in conjunction with ILEC unbundled network
elements ("UNE"); (iii) in those areas where the Company has not yet deployed
local facilities infrastructure, or in those areas where the Company has not yet
achieved significant market penetration, reselling the ILECs' local services
pursuant to state commission-mandated wholesale discounts; and (iv) entering
into agreements with various ILECs and IXCs for termination and origination of
traffic for the Company's on-net local customers. The Company believes this
network deployment strategy, along with its ability to leverage its existing
customer base and demonstrated sales and provisioning expertise, will help to
produce rapid penetration into local markets. Additionally, the Company believes
that the bundling of local service with its long distance or data services will
enhance customer retention and further enhance operating margins.
 
     Four phases of the Company's network expansion are anticipated to take
place by the end of 1999. These phases are as follows:
 
     IXC PLATFORM.  The Company intends to deploy and have operational the
following switching platforms by mid-1999: (i) in Los Angeles, a DMS 250/300
digital switch, which combines on a single platform the DMS 250's interexchange
switching capabilities and the DMS 300's international gateway capabilities;
(ii) in Chicago, a DMS 250 interexchange switch; (iii) in New York City, a
Lucent 5ESS equipped with interexchange capabilities; and (iv) in Atlanta, a
Lucent 5ESS switch, which combines the interexchange switching platform with a
local switching platform. Based upon current traffic patterns and volumes the
Company believes that the deployment of this interexchange switching capacity
will enable the Company to increase the on-net traffic generated by its current
customer base.
 
     LOCAL NORTHEAST PLATFORM.  The Company intends to deploy local switching
infrastructure in the Northeastern United States as the necessary
interconnection agreements with Bell Atlantic and SNET are completed, which will
allow the Company to take advantage of its customer concentration
 
                                       65
<PAGE>   71
 
in this region. While the Company is still evaluating various network
configurations, it is the Company's current intention to deploy a Lucent 5ESS
switch in both Boston and New York, along with numerous circuit and fast packet
access nodes located in central offices and targeted buildings throughout its
Northeastern region.
 
     LOCAL SOUTHEAST PLATFORM.  The Company intends to deploy local switching
infrastructure in the Southeastern United States as the necessary
interconnection agreements with Bell South and GTE are completed, which will
allow the Company to take advantage of its customer concentration in this
region. While the Company is still evaluating various network configurations, it
is the Company's current intention by mid-1999 to install a Lucent 5ESS switch
in both Orlando and Atlanta, along with numerous circuit and fast packet access
nodes located in central offices and targeted buildings throughout its
Southeastern region.
 
     SERVICE BUILDER.  Concurrently with the build-out of its IXC and local
network infrastructure, it is the Company's intention to deploy Service Builder,
Nortel's next generation AIN platform as an extension of the SS7 technology
embedded in the Company's network protocol. Specific value-added features
currently supported by Service Builder include: (i) "500 number" technology;
(ii) "follow me" services; (iii) local number portability (mandated by the
Telecommunications Act); (iv) mass customization of number translation services;
and (v) deployment of virtual private networks. The Company expects to begin
offering some of these services by the first quarter of 1999.
 
  INTERNATIONAL PLATFORM
 
     The Company's switch in Quincy, Massachusetts has international gateway
capabilities. To increase its opportunities in the Pacific Rim, the Company also
plans to deploy a Nortel international gateway switch in its Los Angeles
switching facility by year end 1998.
 
  SPRINT AGREEMENT
 
     In those geographic areas in which the Company has not deployed network
elements, it contracts for and resells long distance domestic and International
services from Sprint. See "Risk Factors -- Dependence Upon Suppliers and Other
Service Providers".
 
MANAGEMENT INFORMATION SYSTEMS, PROVISIONING, BILLING AND COLLECTIONS
 
  OVERVIEW
 
     The Company is committed to the continued development and successful
implementation of an integrated provisioning, billing, collection and customer
service system that provides accurate and timely information to both the Company
and its customers. The Company's billing system is designed to provide access to
a broad range of information on individual customers, including their call
volume, patterns of usage and billing history. This same information is used by
the Company to identify customer trends and to proactively support the Company's
sales and marketing efforts.
 
     In connection with its anticipated growth, the Company has incurred and
expects to incur significant costs to upgrade its information technology
systems. The new system being developed by the Company is built on an open
scalable client/server Oracle platform and is expected to better integrate the
Company's operations, both geographically and among departments. There can be no
assurance that the Company will realize the intended benefits from this new
system or that the Company will not incur significant unanticipated costs in
deploying this system. See "Risk Factors -- Dependence on Billing, Customer
Service and Information Systems".
 
  PROVISIONING
 
     The Company believes that a significant ongoing challenge for ICPs will be
to continuously improve provisioning systems, which includes the complex process
of transitioning customers to
 
                                       66
<PAGE>   72
 
their proprietary networks. Accordingly, the Company will continue to identify
and focus on implementing the best provisioning practices in each of its markets
to provide for rapid, seamless transition of customers from the ILEC to the
Company. To support the provisioning of its services, the information platform
being developed by the Company is designed to deliver information and automated
ordering and provisioning capability directly to the end user as well as to the
Company's internal staff. The Company believes that these practices and its
comprehensive information technology platform, as developed, will provide the
Company with a long-term competitive advantage and allow it to more rapidly
implement switched local services in its markets and to shorten the time between
the receipt of a customer order and the generation of revenue.
 
     The Company's Provisioning Department consists of four discrete areas:
General Provisioning, Dedicated Access Services, Toll-Free Services and Reseller
and Agent Provisioning and Support. The Director of Provisioning has over six
years of telecommunications provisioning experience with the Company. Additional
members of the Provisioning Department management team include (i) the Dedicated
Access Services Manager with over seven years of telecommunications provisioning
experience with the Company; (ii) the Toll-Free Services Manager with four years
of telecommunications provisioning experience with the Company; and (iii) two
Assistant Managers of Provisioning, each with over four years of
telecommunications provisioning experience with the Company.
 
  BILLING
 
     The Company maintains within its internal OSS all customer information,
operational data, accounts receivable information, rating rules and tables, and
tax tables necessary for billing its customers. The Company collects and
processes on a daily basis all usage information from its own network and from
the networks of third-party providers. The actual process of applying rating and
taxing information to the millions of individual message units generated each
month, and of generating invoice print files, is out-sourced to a third party
utilizing both a redundant high-speed IBM MVS mainframe and the proven PL/1
language. Printing of invoices is outsourced to a high-speed print shop, and the
mailing of all invoices is currently handled directly by the Company. To
optimize both cash flow and internal work flow metrics, the Company currently
utilizes four billing cycles per month. Additional billing cycles will be added
as dictated by customer growth. To ensure the quality of the billing process,
the Company utilizes strict quality control checks including boundary and
statistical variation testing, sample pricing matrices and direct sampling.
 
EMPLOYEES
 
     The Company's departments have a proven structure including a "growth from
within" philosophy providing opportunities first, to the extent possible, to
existing employees. The Company believes that this philosophy has increased
employee retention and resulted in the Company's operations being managed by
individuals with significant telecommunications experience with the Company. In
addition, the Company believes that the long tenure, extensive experience and
proven teamwork of its Sales, Customer Service, Provisioning, Billing and
Collections management teams is a competitive advantage when compared to
emerging ICPs lacking the extensive cooperative management experience enjoyed by
the Company.
 
     As of July 15, 1998, the Company employed 276 people, consisting of 152 in
sales and marketing, 32 in customer service, 22 in provisioning, 18 in
production/billing, 13 in finance, 10 in networks, eight in information
technology/MIS, nine in collections and 12 in other departments. The Company has
also recently hired a Director of Human Resources to help manage the Company's
growing employee base. In connection with its growth strategy, the Company
currently anticipates hiring a significant number of additional personnel in
sales and other areas of the Company's operations by year end 1999. As a result
of the intense competition for qualified information technology personnel, the
Company also uses third-party information technology consultants. The Company's
employees are not unionized, and the Company believes its relations with its
employees
                                       67
<PAGE>   73
 
are good. The Company's success will continue to depend in part on its ability
to attract and retain highly qualified employees. See "Risk Factors --
Management of Rapid Growth" and " -- Dependence on Key Personnel".
 
PROPERTIES
 
     The Company's corporate headquarters are located in a 39,500-square foot
facility in Quincy, Massachusetts. The Quincy facility also serves as a sales
office and includes the Company's customer service operations, certain network
facilities and its Network Operations Center. The Quincy facility is leased from
an affiliate of the Company. See "Certain Transactions". The Company currently
leases nine additional facilities for current or planned sales offices. The
Company also leases real estate to house its telemarketing center in Largo,
Florida and switching facilities in Los Angeles, Chicago and Orlando. The
aggregate amount paid by the Company under its leases in 1997 was approximately
$733,000. Although the Company's facilities are adequate at this time, the
Company believes that it will be required to lease additional facilities,
including additional sales offices and switching facilities, as a result of its
anticipated growth.
 
LEGAL MATTERS
 
     From time to time the Company is party to routine litigation and
proceedings in the ordinary course of its business. The Company is not aware of
any current or pending litigation to which the Company is or may be a party that
the Company believes could have a material adverse effect on the Company's
results of operations or financial condition.
 
INDUSTRY OVERVIEW
 
  HISTORY AND INDUSTRY DEVELOPMENT
 
     Prior to 1984, AT&T dominated both the local exchange and long distance
marketplaces by owning the operating entities that provided both local exchange
and long distance services to most of the U.S. population. Although long
distance competition began to emerge in the late 1970s, the critical event
triggering the growth of long distance competition was the breakup of AT&T and
the separation of its local and long distance businesses as mandated by the
Modified Final Judgment relating to the breakup of AT&T (the "MFJ"). To foster
competition in the long distance market, the MFJ prohibited AT&T's divested
local exchange businesses, the RBOCs, from acting as single-source providers of
telecommunications services.
 
     Although the MFJ established the preconditions for competition in the
market for long distance services in 1984, the market for local exchange
services has until recently been virtually closed to competition and has largely
been dominated by regulated monopolies. Efforts to open the local exchange
market began in the late 1980s on a state-by-state basis when CLECs began
offering dedicated private line transmission and access services. These types of
services together currently account for approximately 12% of total local
exchange revenue. CLECs were restricted, often by state laws, from providing
other, more frequently used services such as basic and switched services, which
today account for approximately 88% of local exchange revenue.
 
     The Telecommunications Act, which was enacted in February 1996, is
considered to be the most comprehensive reform of the nation's
telecommunications laws and affects the development of competition for local
telecommunications services. Specifically, certain provisions of the
Telecommunications Act provide for (i) the removal of legal barriers to entry to
the local telecommunications services market; (ii) the interconnection of ILEC
networks with competitors' networks; (iii) the establishment of procedures and
requirements to be followed by the RBOCs, including the requirement that RBOCs
offer local services for resale as a precondition to entering into the long
distance and telecommunications equipment manufacturing markets; and (iv) the
relaxation of the regulation of certain telecommunications services provided by
LECs and others. The Company
 
                                       68
<PAGE>   74
 
believes the Telecommunications Act will promote significant growth in the local
telecommunications market as new market entrants provide expanded service
offerings.
 
     The Telecommunications Act further increases the opportunities available to
CLECs by requiring the RBOCs and other ILECs to offer various network elements
such as switching, transport and loops (i.e., the facilities connecting a
customer's premises to a LEC central office) on an unbundled and
non-discriminatory basis. RBOCs also are required to offer their retail services
at wholesale rates for resale by other companies. By offering such services,
RBOCs also meet certain of the requirements contained in the Telecommunications
Act in order to gain FCC approval to provide in-region long distance services.
Although certain provisions of the Telecommunications Act restricting the RBOCs'
ability to provide in-region long distance services have been held
unconstitutional by a Federal district court, the Company believes that
significant parts of such decision may be reversed and vacated on appeal, but no
assurance can be made as to the outcome.
 
     The continuing deregulation of the telecommunications industry and
technological change have resulted in an increasingly information-intensive
business environment. Regulatory, technological, marketing and competitive
trends have expanded substantially the Company's opportunities in the converging
voice and data communications services markets. For example, technological
advances, including rapid growth of the Internet, the increased use of packet
switching technology for voice communications and the growth of multimedia
applications, are expected to result in substantial growth in the high-speed
data services market.
 
     This new market opportunity will permit competitive providers who can
manage the operational and marketing implementation to offer a full range of
telecommunications services, including local and long distance calling,
toll-free calling, custom calling features, data services, Internet access and
cellular services. The Company believes that customers will prefer a single
source for all of their voice and data telecommunications requirements,
including products, billing and service. Telecommunications companies with an
established base of long distance customers will have the opportunity to sell
additional services to such customers. The Company believes that a one-stop
provider of integrated communications services will have the opportunity to
penetrate its existing markets, expand its customer base, capture a larger
portion of its customers' total expenditures on communication services and
reduce customer turnover. Furthermore, companies that develop their own networks
will have the opportunity to migrate customers from off-net to on-net, thereby
increasing long-term operating margins and giving such companies greater control
over their network operations. See "Risk Factors -- Competition", "-- The
Telecommunications Act and Other Regulation" and "-- Impact of Technological
Change".
 
     The Company also believes that small and medium-sized businesses have
historically been underserved with respect to customer service and support.
Because, the Company believes, RBOCs and the largest national carriers primarily
concentrate their sales and marketing efforts on residential and large business
customers, there is a significant market opportunity with respect to small and
medium-sized businesses. Geographically, the Company believes that the
Northeastern and Southeastern regions of the United States are attractive
markets due to a number of factors, including (i) the population density in the
Northeast; (ii) a large number of rapidly growing metropolitan clusters in the
Southeast, such as Atlanta, Miami/Fort Lauderdale and Orlando; and (iii) the
relatively small number of significant competitors to the ILECs.
 
  TELECOMMUNICATIONS SERVICES MARKET
 
     Overview of U.S. Market.  The U.S. market for telecommunications services
can be divided into three basic sectors: long distance services, local exchange
services and Internet access services. In 1997, it is estimated that, in the
United States, long distance services generated revenue of $104.6 billion, local
exchange services accounted for revenue of $92.4 billion, and Internet services
revenue totaled $6.3 billion. Revenue for both local exchange and long distance
services include amounts
 
                                       69
<PAGE>   75
 
charged by long distance carriers and subsequently paid to ILECs (or, where
applicable, CLECs) for long distance access.
 
     Long Distance Services.  A long distance telephone call can be envisioned
as consisting of three segments. Starting with the originating customer, the
call travels along a local exchange network to a long distance carrier's point
of presence ("POP"). At the POP, the call is combined with other calls and sent
along a long distance network to a POP on the long distance carrier's network
near where the call will terminate. The call is then sent from this POP along a
local network to the terminating customer. Long distance carriers provide only
the connection between the two local networks, and, unless the long distance
carrier is a local service provider, pay access charges to LECs for originating
and terminating calls.
 
     The following diagram is a simplified illustration of a typical long
distance network call carried by the Company:
 
                                   [DIAGRAM]
 
     Local Exchange Services.  A local call is one that does not require the
services of a long distance carrier. In general, the local exchange carrier
connects end user customers within a LATA and also provides the local portion of
most long distance calls.
 
     The following diagram is a simplified illustration of a typical local
network call:
 
                                   [DIAGRAM]
 
                                       70
<PAGE>   76
 
     Internet Service.  Internet services are generally provided in at least two
distinct segments. A local network connection is required from the ISP customer
to the ISP's local facilities. For large, communication-intensive users and for
content providers, the connections are typically unswitched, dedicated
connections provided by ILECs, CLECs or ICPs, either as independent service
providers or, in some cases, by a company that is both a CLEC and an ISP. For
residential and small and medium-sized business users, these connections are
generally public switched telephone network ("PSTN") connections obtained on a
dial-up access basis as a local exchange telephone call. Once a local connection
is made to the ISP's local facilities, information can be transmitted and
obtained over a packet-switched IP data network, which may consist of segments
provided by many interconnected networks operated by a number of ISPs. The
collection of interconnected networks makes up the Internet. A key feature of
Internet architecture and packet-switching is that a single dedicated channel
between communication points is never established, which distinguishes
Internet-based services from the PSTN.
 
COMPETITION
 
  OVERVIEW
 
     The Company operates in a highly competitive industry and believes that it
does not have significant market share in any market in which it operates. The
Company expects that competition will continue to intensify in the future due to
regulatory changes, including the continued implementation of the
Telecommunications Act, and the increase in the size, resources and number of
market participants. In each of its markets, the Company will face competition
for local service from larger, better capitalized ILECs and CLECs. Additionally,
the long distance market is already significantly more competitive than the
local exchange market because the ILECs, prior to enactment of the
Telecommunications Act, generally had a monopoly position within the local
exchange market. While new business opportunities will be made available to the
Company through the Telecommunications Act and other federal and state
regulatory initiatives, regulators are likely to provide the ILECs with an
increased degree of flexibility with regard to pricing of their services as
competition increases.
 
     Competition for the Company's products and services is based on price,
quality, reputation, name recognition, network reliability, service features,
billing services, perceived quality and responsiveness to customers' needs.
While the Company believes that it currently has certain advantages relating to
price, quality, customer service, and responsiveness to customer needs, there is
no assurance that the Company will be able to maintain these advantages or
obtain additional advantages. A continuing trend toward business combinations
and alliances in the telecommunications industry may create significant new
competitors to the Company. Many of the Company's existing and potential
competitors have financial, technical and other resources significantly greater
than those of the Company. In addition, in December 1997 the FCC issued rules to
implement the provisions of the World Trade Organization Agreement on Basic
Telecommunications, which was drafted to liberalize restrictions on foreign
ownership of domestic telecommunications companies and to allow foreign
telecommunications companies to enter domestic markets. The new FCC rules went
into effect in February 1998 and are expected to make it substantially easier
for many non-U.S. telecommunications companies to enter the U.S. market, thus
further increasing the number of competitors. The new rules will also give
non-U.S. individuals and corporations greater ability to invest in U.S.
telecommunications companies, thus increasing the financial and technical
resources potentially available to the Company and its existing and potential
competitors. See "Risk Factors -- Competition", "-- The Telecommunications Act
and Other Regulation" and "Government Regulation".
 
  LONG DISTANCE MARKET
 
     The long distance telecommunications industry is highly competitive and
affected by the introduction of new services by, and the market activities of,
major industry participants. The Company competes against various national and
regional long distance carriers, including both
 
                                       71
<PAGE>   77
 
facilities-based providers and switchless resellers offering essentially the
same services as the Company. In addition, significant competition is expected
to be provided by ILECs including, when authorized, RBOCs. The Company's success
will depend upon its ability to provide high-quality services at prices
generally competitive with, or lower than, those charged by its competitors. In
addition, the long distance industry is characterized by a high level of
customer attrition or "churn". Such attrition is attributable to a variety of
factors, including initiatives of competitors as they engage in advertising
campaigns, marketing programs and cash payments and other incentives. End users
are often not obligated to purchase any minimum usage amount and can discontinue
service without penalty at any time. While the Company believes its customer
turnover rate is lower than that of many of its competitors, the Company's
revenue has been, and is expected to continue to be, affected by churn.
 
     AT&T, MCI, Sprint and other carriers have implemented new price plans aimed
at residential customers with significantly simplified rate structures, which
may have the impact of lowering overall long distance prices. There can also be
no assurance that long distance carriers will not make similar offerings
available to the small to medium-sized businesses that the Company primarily
serves. While the Company believes small and medium-sized business customers are
not aggressively targeted by large long distance providers such as AT&T, MCI and
Sprint, there can be no assurance the Company's customers and potential
customers will not be targeted by these or other providers in the future.
Additional pricing pressure may come from IP transport, which is a developing
use of packet-switched technology that can transmit voice communications at a
cost that may be below that of traditional circuit-switched long distance
service. While IP transport is not yet available in all areas, requires the
dialing of additional digits, and generally produces sound quality inferior to
traditional long distance service, it could eventually be perceived as a
substitute for traditional long distance service and put pricing pressure on
long distance rates. Any reduction in long distance prices may have a material
adverse effect on the Company's results of operations.
 
     One of the Company's principal competitors, Sprint, is also a major
supplier of services to the Company. The Company both links its switching
equipment with transmission facilities and services purchased or leased from
Sprint, and resells services obtained from Sprint. See "Business --
Network -- Sprint Agreement". There can be no assurance that Sprint will
continue to offer services to the Company at competitive rates or on attractive
terms, if at all, and any failure to do so could have a material adverse effect
on the Company. See "Risk Factors -- Dependence Upon Suppliers and Other Service
Providers".
 
  LOCAL EXCHANGE MARKET
 
     Under the Telecommunications Act and related federal and state regulatory
initiatives, barriers to local exchange competition are being removed. In local
telecommunication markets, the Company's primary competitor will be the ILEC
serving each geographic area. ILECs are established providers of dedicated and
local telephone services to all or virtually all telephone subscribers within
their respective service areas. ILECs also have long-standing relationships with
regulatory authorities at the federal and state levels. While recent FCC
administrative decisions and initiatives provide increased business
opportunities to voice, data and Internet-service providers, they also provide
the ILECs with increased pricing flexibility for their private line, special
access and switched access services. In addition, with respect to competitive
access services, the FCC recently proposed a rule that would provide for
increased ILEC pricing flexibility and deregulation for such access services
either automatically or after certain competitive levels are reached. If the
ILECs are allowed additional flexibility by regulators to offer discounts to
large customers through contract tariffs, decide to engage in aggressive volume
and term discount pricing practices for their customers, or seek to charge
competitors excessive fees for interconnection to their networks, the revenue of
competitors to the ILECs could be materially adversely affected. If future
regulatory decisions afford the ILECs increased access services, pricing
flexibility or other regulatory relief, such decisions could also have a
material adverse effect on competitors to the ILECs.
 
                                       72
<PAGE>   78
 
     The Company also will face competition or prospective competition in local
markets from other carriers, many of which have significantly greater financial
resources than the Company. For example, AT&T, MCI and Sprint have each begun to
offer local telecommunications services in major U.S. markets using their own
facilities or by resale of the ILECs' or other providers' services. In addition
to these long distance service providers, entities that currently offer or are
potentially capable of offering local switched services include companies that
have previously operated as competitive access providers, cable television
companies, electric utilities, microwave carriers, wireless telephone system
operators and large customers who build private networks. These entities, upon
entering into appropriate interconnection agreements or resale agreements with
ILECs, including RBOCs, could offer single-source local and long distance
services, similar to those offered or proposed to be offered by the Company.
 
     In addition, a continuing trend towards business combinations and alliances
in the telecommunications industry may create significant new competitors to the
Company. The proposed acquisition of GTE Corp. by Bell Atlantic Corp., the
proposed merger of SBC and Ameritech, the merger of WorldCom and MCI, AT&T's
proposed acquisition of Telecommunications Inc. and its acquisition of Teleport
Communications Group, Inc., Teleglobe Inc.'s proposed acquisition of Excel
Communications, and SBC's proposed acquisition of SNET are examples of some of
the alliances that are being formed. Many of these combined entities will have
resources far greater than those of the Company. These combined entities may
provide a bundled package of telecommunications products, including local and
long distance telephony, that is in direct competition with the products offered
or proposed to be offered by the Company, and may be capable of offering these
products sooner and at more competitive rates than the Company.
 
  WIRELESS MARKET
 
     The Company will also face competition from fixed wireless services,
including MMDS, LMDS, 24 GHz and 38 GHz wireless communications systems, FCC
Part 15 unlicensed wireless radio devices, and other services that use existing
point-to-point wireless channels on other frequencies. In addition, the FCC has
allocated a number of spectrum blocks for use by wireless devices that do not
require site or network licensing. A number of vendors have developed such
devices that may provide competition to the Company, in particular for certain
low data-rate transmission services.
 
     With respect to mobile wireless telephone system operators, the FCC has
authorized cellular, PCS, and other CMRS providers to offer wireless services to
fixed locations, rather than just to mobile customers, in whatever capacity such
CMRS providers choose. Previously, cellular providers could provide service to
fixed locations only on an ancillary or incidental basis. The authority to
provide fixed as well as mobile services will enable CMRS providers to offer
wireless local loop service and other services to fixed locations (e.g., office
and apartment buildings) in direct competition with the Company and existing
providers of traditional wireless telephone service.
 
  OTHER
 
     Section 271 of the Telecommunications Act prohibits an RBOC from providing
long distance service that originates (or in certain cases terminates) in one of
its in-region states, with several limited exceptions, until the RBOC has
satisfied certain statutory conditions in that state and has received the
approval of the FCC. The FCC has denied the following applications for such
approval: SBC's Texas application in June 1998; SBC's Oklahoma application in
June 1997; Ameritech's Michigan application in August 1997; and BellSouth
Corporation's applications for South Carolina and Louisiana in December 1997 and
February 1998, respectively. The Company anticipates that a number of RBOCs will
file additional applications for in-region long distance authority in 1998. Bell
Atlantic recently received conditional approval from the New York Public Service
Commission of its Section 271 application for New York State. Thus, it is
expected that Bell Atlantic will file its Section 271 application with the FCC
in the near future. The FCC has 90 days from the date an
 
                                       73
<PAGE>   79
 
application for in-region long distance authority is filed to decide whether to
grant or deny the application.
 
     Once the RBOCs are allowed to offer widespread in-region long distance
services, both they and the largest IXCs will be in a position to offer
single-source local and long distance service. On December 31, 1997, a United
States District Court judge in Texas held unconstitutional certain sections of
the Telecommunications Act, including Section 271. Section 271 includes a
"competitive checklist" that RBOCs must satisfy prior to obtaining authority to
provide in-region, interLATA long-distance service. This decision would permit
the three RBOCs involved in the suit immediately to begin offering widespread
in-region long distance services. The decision, however, was stayed on February
11, 1998 by the District Court pending the outcome of an appeal on the merits to
the U.S. Court of Appeals for the Fifth Circuit. On September 4, 1998, the Fifth
Circuit reversed the District Court's ruling. Among other things, the Fifth
Circuit found sec.sec.271-275 of the Telecommunications Act to be non-punitive
in character and, therefore, not a bill of attainder as that term has been
defined by the Superior Court.
 
     In addition, new FCC rules went into effect in February 1998 that will make
it substantially easier for many non-U.S. telecommunications companies to enter
the U.S. market, thus potentially further increasing the number of competitors.
 
     The market for data communications and Internet access services is also
extremely competitive. There are no substantial barriers to entry, and the
Company expects that competition will intensify in the future. The Company's
success selling these services will depend heavily upon its ability to provide
high quality Internet connections at competitive prices. See "Risk Factors --
Competition".

                             GOVERNMENT REGULATION
 
     The following summary of regulatory developments and legislation does not
purport to describe all present and proposed federal, state and local
regulations and legislation affecting the telecommunications industry. Other
existing federal, state and local legislation and regulations are currently the
subject of judicial proceedings, legislative hearings, and administrative
proposals that could change, in varying degrees, the manner in which the
telecommunications industry operates. Neither the outcome of these proceedings,
nor their impact upon the telecommunications industry or the Company, can be
predicted at this time. This section also summarizes regulatory and tariff
issues pertaining to the operation of the Company.
 
OVERVIEW
 
     The Company's services are subject to regulation by federal, state and
local government agencies. The FCC exercises jurisdiction over all facilities
and services of telecommunications common carriers to the extent those
facilities are used to provide, originate or terminate domestic (interstate) or
international communications. State regulatory commissions retain jurisdiction
over carriers' facilities and services to the extent they are used to originate
or terminate intrastate communications. Municipalities and other local
government agencies may require carriers to obtain licenses or franchises
regulating use of public rights-of-way necessary to install and operate their
networks. The networks are also subject to numerous local regulations such as
building codes, franchises, and rights of way licensing requirements. Many of
the regulations issued by these regulatory bodies may change, the results of
which the Company is unable to predict. See "Risk Factors -- The
Telecommunications Act and Other Regulation".
 
THE FEDERAL TELECOMMUNICATIONS ACT OF 1996
 
     STATUTORY REQUIREMENTS.  On February 1, 1996, the U.S. Congress enacted
comprehensive telecommunications legislation, which the President signed into
law on February 8, 1996. The Company believes that this legislation is likely to
enhance competition in the local telecommunications marketplace because it (i)
gives the FCC authority to preempt state and local entry barriers, (ii) requires
ILECs to provide interconnection to their facilities, (iii) facilitates
end-users' choice to switch service providers from ILECs to CLECs and (iv)
proscribes the imposition of discriminatory or anticompetitive requirements by
state or local governments for use of public rights of way.
 
     The Telecommunications Act requires all LECs (including ILECs and CLECs)
(i) not to prohibit or unduly restrict resale of their services; (ii) to provide
local number portability; (iii) to provide dialing parity and nondiscriminatory
access to telephone numbers, operator services, directory assistance and
directory listings; (iv) to afford access to poles, ducts, conduits and
rights-of-way; and (v) to establish reciprocal compensation arrangements for the
transport and termination of local telecommunications traffic. It also requires
ILECs to negotiate local interconnection agreements in good faith and to provide
interconnection (a) for the transmission and routing of telephone exchange
service and exchange access, (b) at any technically feasible point within the
ILEC's network, (c) that is at least equal in quality to that provided by the
ILEC to itself, its affiliates or any other party to which the ILEC provides
interconnection, and (d) at rates, terms and conditions that are just,
reasonable and nondiscriminatory. ILECs also are required under the
Telecommunications Act to provide nondiscriminatory access to network elements
on an unbundled basis at any technically feasible point, to offer their local
retail telephone services for resale at wholesale rates, and to facilitate
collocation of equipment necessary for competitors to interconnect with or
access unbundled network elements ("UNEs").
 
     In addition, the Telecommunications Act requires RBOCs to comply with
certain safeguards and offer interconnection that satisfies a prescribed
14-point competitive checklist before the RBOCs are permitted to provide
in-region interLATA (i.e., interexchange long distance) services. These
safeguards are designed to ensure that the RBOCs' competitors have access to
local exchange and
 
                                       75
<PAGE>   81
 
exchange access services on nondiscriminatory terms and that subscribers of
regulated non-competitive RBOC services do not subsidize their provision of
competitive services. The safeguards also are intended to promote competition by
preventing RBOCs from using their market power in local exchange services to
obtain an anti-competitive advantage in the provision of other services.
 
     Three RBOCs, Ameritech Corp., SBC Communications Inc. (formerly
Southwestern Bell Corp.) and BellSouth Corp., have filed applications with the
FCC for authority to provide in-region interLATA service in selected states. The
FCC has denied all such RBOC applications for in-region long distance authority
filed to date. The denials of certain of these RBOC applications by the FCC are
the subjects of judicial appeals and petitions for rehearing at the FCC. Other
RBOCs have begun the process of applying to provide in-region interLATA service
by filing with state commissions notice of their intent to file at the FCC.
 
     In addition, several RBOCs have challenged the constitutionality of certain
provisions of the Telecommunications Act that bar the RBOCs from providing
in-region interexchange and other services by filing a lawsuit in the U.S.
District Court for the Northern District of Texas (captioned SBC Communications,
Inc. v. FCC, Civil Action No. 7:97-CV-163-X (Kendall, J.)). Judge Kendall issued
an order in that case that invalidated Sections 271-273 of the
Telecommunications Act as they pertain to SBC, US West and Bell Atlantic, after
finding that these provisions violated the constitutional prohibition against
"bills of attainder". Judge Kendall's decision was appealed to the U.S. Court of
Appeals for the Fifth Circuit; on September 4, 1998, the Fifth Circuit reversed
the District Court's ruling.
 
     The Telecommunications Act also granted important regulatory relief to
industry segments that compete with CLECs. ILECs were given substantial new
pricing flexibility. RBOCs have the ability to provide out-of-region
long-distance services and, if they obtain authorization and under prescribed
circumstances, may provide additional in-region long-distance services. RBOCs
also were granted new rights to provide certain cable TV services. IXCs were
permitted to construct their own local facilities and/or resell local services.
State laws no longer may require cable television service providers ("CATVs") to
obtain a franchise before offering telecommunications services nor permit CATVs'
franchise fees to be based on their telecommunications revenue. In addition,
under the Telecommunications Act all utility holding companies are permitted to
diversify into telecommunications services through separate subsidiaries. See
"Risk Factors -- Competition".
 
     FCC RULES IMPLEMENTING THE LOCAL COMPETITION PROVISIONS OF THE
TELECOMMUNICATIONS ACT. On August 8, 1996, the FCC released a First Report and
Order, a Second Report and Order and a Memorandum Opinion and Order in its CC
Docket 96-98 (combined, the "Interconnection Orders") that established a
framework of minimum, national rules enabling state Public Service Commissions
("PSCs") and the FCC to begin implementing many of the local competition
provisions of the Telecommunications Act. In its Interconnection Orders, the FCC
prescribed certain minimum points of interconnection necessary to permit
competing carriers to choose the most efficient points at which to interconnect
with the ILECs' networks. The FCC also adopted a minimum list of unbundled
network elements that ILECs must make available to competitors upon request and
a methodology for states to use in establishing rates for interconnection and
the purchase of unbundled network elements. The FCC also adopted a methodology
for states to use when applying the Telecommunications Act's "avoided cost
standard" for setting wholesale prices with respect to retail services.
 
     The following summarizes the key issues addressed in the Interconnection
Orders:
 
     - INTERCONNECTION.  ILECs are required to provide interconnection for
       telephone exchange or exchange access service, or both, to any requesting
       telecommunications carrier at any technically feasible point. The
       interconnection must be at least equal in quality to that provided by the
       ILEC to itself or its affiliates and must be provided on rates, terms and
       conditions that are just, reasonable and nondiscriminatory.
 
                                       76
<PAGE>   82
 
     - ACCESS TO UNBUNDLED ELEMENTS.  ILECs are required to provide requesting
       telecommunications carriers with nondiscriminatory access to network
       elements on an unbundled basis at any technically feasible point on
       rates, terms, and conditions that are just, reasonable and
       nondiscriminatory. At a minimum, ILECs must unbundle and provide access
       to network interface devices, local loops, local and tandem switches
       (including all software features provided by such switches), interoffice
       transmission facilities, signaling and call-related database facilities,
       operations support systems, and information and operator and directory
       assistance facilities. Further, ILECs may not impose restrictions,
       limitations or requirements upon the use of any unbundled network
       elements by other carriers.
 
     - METHODS OF OBTAINING INTERCONNECTION AND ACCESS TO UNBUNDLED
       ELEMENTS.  ILECs are required to provide physical collocation of
       equipment necessary for interconnection or access to unbundled network
       elements at the ILEC's premises, except that the ILEC may provide virtual
       collocation if it demonstrates to the PSC that physical collocation is
       not practical for technical reasons or because of space limitations.
 
     - TRANSPORT AND TERMINATION CHARGES.  The FCC rules require that LEC
       charges for transport and termination of local traffic delivered to them
       by competing LECs must be cost-based and should be based on the LECs'
       Total Element Long-Run Incremental Cost ("TELRIC") of providing that
       service. However, as discussed below, the FCC's pricing and costing rules
       have been vacated by the U.S. Court of Appeals for the Eighth Circuit.
 
     - PRICING METHODOLOGIES.  New entrants were required to pay for
       interconnection and unbundled elements at rates based on the ILEC's
       TELRIC of providing a particular network element plus a reasonable share
       of forward-looking joint and common costs, and may include a reasonable
       profit. However, as discussed below, these rules have been vacated by the
       Eighth Circuit.
 
     - RESALE.  ILECs were required to offer for resale any telecommunications
       service that they provide at retail to subscribers who are not
       telecommunications carriers. PSCs were required to identify which
       marketing, billing, collection and other costs will be avoided or that
       are avoidable by ILECs when they provide services on a wholesale basis
       and to calculate the portion of the retail rates for those services that
       is attributable to the avoided and avoidable costs. However, as discussed
       below, the specific federal pricing requirements have been vacated by the
       Eighth Circuit.
 
     - ACCESS TO RIGHTS-OF-WAY.  The FCC established procedures and guidelines
       designed to facilitate the negotiation and mutual provision of
       nondiscriminatory access by telecommunications carriers and utilities to
       their poles, ducts, conduits, and rights-of-way.
 
     - UNIVERSAL SERVICE REFORM.  All telecommunications carriers, including the
       Company, are required to contribute funding for universal service
       support, on an equitable and nondiscriminatory basis, in an amount
       sufficient to preserve and advance universal service pursuant to a
       specific or predictable universal service funding mechanism. On May 8,
       1997, the FCC released an order implementing these requirements by
       reforming its existing access charge and universal service rules. See
       "-- Universal Service Reform" below.
 
     Most provisions of the Interconnection Orders were appealed. Numerous
appeals were consolidated for consideration by the Eighth Circuit Court of
Appeals (captioned Iowa Utilities Board v. FCC). On July 18, 1997, the Court of
Appeals released its decision regarding issues raised in the consolidated
appeals. The Interconnection Orders were upheld in part and reversed in part. A
non-exclusive list of decisions rendered include:
 
     - The FCC exceeded its jurisdiction in establishing rules governing the
       prices that ILECs may charge competitors for interconnection, unbundled
       access and resale. The Court ruled that the authority to establish prices
       for local communications facilities and services is reserved to
 
                                       77
<PAGE>   83
 
       the states and, thus, vacated the FCC's pricing rules (except as they
       apply to CMRS providers).
 
     - The FCC's "pick and choose" rule, which allows competitors to select
       individual terms of previously approved interconnection agreements for
       their own use, conflicts with the purposes of the Telecommunications Act,
       and also was vacated.
 
     - The FCC lacks authority to hear formal complaints that involve the review
       and/or enforcement of certain terms of local interconnection agreements
       approved by state commissions.
 
     - The FCC lacks authority to require interconnection agreements that were
       negotiated before the enactment of the Telecommunications Act to be
       submitted for state commission approval.
 
     - The FCC may not adopt a blanket requirement that state interconnection
       rules must be consistent with the FCC's regulations.
 
     - The FCC correctly concluded that ILEC operations support systems,
       operator services and vertical switching features qualify as network
       elements that are subject to the unbundling requirements of the
       Telecommunications Act.
 
     - The FCC's definition of "technically feasible" was upheld for purposes of
       deciding where ILECs must permit interconnection by competitors, but the
       FCC's use of this term to determine the elements that must be unbundled
       was rejected.
 
     - The FCC erred in deciding that ILECs could be required by competitors to
       provide interconnection and unbundled network elements at levels of
       quality that exceed those levels at which ILECs provide such services to
       themselves.
 
     - The FCC cannot require ILECs to recombine network elements for
       competitors, but competitors may recombine such network elements
       themselves as necessary to provide telecommunications services.
 
     - Claims that the unbundling rules constitute an unconstitutional taking
       were not decided because they were either raised by parties that lacked
       standing or were not ripe for review.
 
     - The FCC rules and policies regarding the ILECs' duty to provide for
       physical collocation of equipment were upheld.
 
     - The FCC rules requiring ILECs to allow the resale of promotional prices
       lasting more than 90 days were upheld.
 
     The Interconnection Orders, and resulting local interconnection rules, were
vacated in part consistent with these decisions. The U.S. Supreme Court has
granted certiorari to review most aspects of the Eighth Circuit decision
regarding the Interconnection Orders. The Company cannot predict the outcome of
this litigation or the requests for reconsideration that remain pending at the
FCC. Notably, the FCC recently made the use of forward looking, economic costs
for the pricing of local interconnection, transport and termination and
unbundled network elements a temporary condition of its approval of the merger
of Bell Atlantic and NYNEX. However, after the FCC indicated in its denial of
Ameritech's application for in-region long distance authority that an RBOC's use
of such forward looking, economic costs is relevant to the issue of whether it
has satisfied the conditions necessary for approval of such an application, the
Eighth Circuit issued a mandamus order instructing the FCC not to enforce such a
requirement.
 
     SECTION 706 FORBEARANCE.  Section 706 of the Telecommunications Act gives
the FCC the right to forebear from regulating a market if the FCC concludes that
such forbearance is necessary to encourage the rapid deployment of advanced
telecommunications capability. Section 706 has not been used to date, but in
January 1998 Bell Atlantic filed a petition under Section 706 seeking to have
the FCC deregulate entirely the provision of packet-switched telecommunications
services.
 
                                       78
<PAGE>   84
 
Similar petitions were later filed by the Alliance for Public Technology and US
West Inc. (currently Media One Group Inc.), and other ILECs are expected to file
similar petitions in the near future.
 
     On August 7, 1998, the FCC released an Order denying requests by the
Regional Bell Operating Companies (RBOCs) that it use Section 706 of the
Telecommunications Act to forbear from regulating advanced telecommunications
services. Instead, the FCC determined that advanced services are
telecommunications services and that ILECs providing advanced services are still
subject to the unbundling and resale obligations of Section 251(c) and the
in-region interLATA restrictions of Section 271.
 
     On the same day, the FCC released a Notice of Proposed Rulemaking ("NPRM")
proposing that ILECs be permitted to offer advanced services through separate
affiliates. Subject to certain restrictions on transfers from the ILEC to the
affiliate, structural separation rules and nondiscrimination safeguards, these
separate affiliates would not be subject to the obligations imposed on ILECs
under Section 251(c), but would remain subject to the in-region interLATA
restrictions imposed on RBOCs and RBOC affiliates by Section 271. In the Order,
the FCC did not specifically authorize ILECs to provide advanced services
through a separate affiliate immediately. ILECs may, of course, immediately
provide advanced services, but until the separate affiliate is properly
established pursuant to rules to be promulgated following comment on the NPRM,
such provision of advanced services will be subject to Section 251. The outcome
of this proceeding could have a material adverse effect on the Company.
 
     In order to assist competing carriers to gain access to ILEC facilities
necessary to provide advanced services, the FCC also proposes to strengthen
collocation and loop unbundling requirements. Finally, the FCC issued a Notice
of Inquiry (NOI) to explore the availability of advanced, high speed
telecommunications services.
 
     OTHER FEDERAL REGULATION.  In general, the FCC has a policy of encouraging
the entry of new competitors in the telecommunications industry and preventing
anti-competitive practices. Therefore, the FCC has established different levels
of regulation for dominant carriers and nondominant carriers. For purposes of
domestic common carrier telecommunications regulation, large ILECs such as GTE
and the RBOCs are currently considered dominant carriers, while CLECs are
considered nondominant carriers.
 
     - TARIFFS.  As a nondominant carrier, the Company may install and operate
       facilities for the transmission of domestic interstate communications
       without prior FCC authorization. Services of nondominant carriers have
       been subject to relatively limited regulation by the FCC, primarily
       consisting of the filing of tariffs and periodic reports. However,
       nondominant carriers like the Company must offer interstate services on a
       nondiscriminatory basis, at just and reasonable rates, and remain subject
       to FCC complaint procedures. With the exception of informational tariffs
       for operator-assisted services and tariffs for interexchange casual
       calling services, the FCC has ruled that IXCs must cancel their tariffs
       for domestic, interstate interexchange services. Tariffs remain required
       for international services. The effectiveness of those orders currently
       is subject to a stay issued by the U.S. Court of Appeals for the District
       of Columbia Circuit. On June 19, 1997, the FCC issued an order granting
       petitions filed by Hyperion Telecommunications Inc. and Time Warner Inc.
       to provide CLECs the option to cease filing tariffs for interstate
       interexchange access services and has proposed to make the withdrawal of
       CLEC access service tariffs mandatory. Pursuant to these FCC
       requirements, the Company has filed and maintains tariffs for its
       interstate services with the FCC. All of the interstate access and retail
       "basic" services (as defined by the FCC) provided by the Company are
       described therein. "Enhanced" services (as defined by the FCC) need not
       be tariffed. The Company believes that its proposed enhanced voice and
       Internet services are "enhanced" services that need not be tariffed.
       However, the FCC is reexamining the "enhanced" definition as it relates
       to IP transport and the Company cannot predict whether the FCC will
       change the classification of such services.
 
                                       79
<PAGE>   85
 
     - INTERNATIONAL SERVICES.  Nondominant carriers such as the Company also
       are required to obtain FCC authorization pursuant to Section 214 of the
       Communications Act and file tariffs before providing international
       communications services. The Company has obtained authority from the FCC
       to provide voice and data communications services between the United
       States and all foreign authorized points.
 
     - ILEC PRICE CAP REGULATION REFORM.  In 1991, the FCC replaced traditional
       rate of return regulation for large ILECs with price cap regulation.
       Under price caps, ILECs can raise prices for certain services by only a
       small percentage each year. In addition, there are constraints on the
       pricing of ILEC services that are competitive with those of CLECs. On
       September 14, 1995, the FCC proposed a three-stage plan that would
       substantially reduce ILEC price cap regulation as local markets become
       increasingly competitive and ultimately would result in granting ILECs
       nondominant status. Adoption of the FCC's proposal to reduce
       significantly its regulation of ILEC pricing would significantly enhance
       the ability of ILECs to compete against the Company and could have a
       material adverse effect on the Company. The FCC released an order on
       December 24, 1996 that adopted certain of these proposals, including the
       elimination of the lower service band index limits on price reductions
       within the access service category. The FCC's December 1996 order also
       eased the requirements necessary for the introduction of new services by
       ILECs. On May 7, 1997, the FCC took further action in its CC Docket No.
       94-1 updating and reforming its price cap plan for the ILECs. Among other
       things, the changes require price cap LECs to reduce their price cap
       indices by 6.5 percent annually, less an adjustment for inflation. The
       FCC also eliminated rules that require ILECs earning more than certain
       specified rates of return to "share" portions of the excess with their
       access customers during the next year in the form of lower access rates.
       These actions could have a significant impact on the interstate access
       prices charged by the ILECs with whom the Company expects to compete.
 
     - ACCESS CHARGES.  Over the past few years, the FCC has granted ILECs
       significant flexibility in pricing their interstate special and switched
       access services. Under this pricing scheme, ILECs may establish pricing
       zones based on access traffic density and charge different prices for
       each zone. The Company anticipates that this pricing flexibility will
       result in ILECs lowering their prices in high traffic density areas, the
       probable area of competition with the Company. The Company also
       anticipates that the FCC will grant ILECs increasing pricing flexibility
       as the number of interconnections and competitors increases. On May 7,
       1997, the FCC took action in its CC Docket No. 96-262 to reform the
       current interstate access charge system. The FCC adopted an order that
       makes various reforms to the existing rate structure for interstate
       access that are designed to move access charges, over time, to more
       economically efficient rate levels and structures. The following is a
       nonexclusive list of actions announced by the FCC:
 
        - SUBSCRIBER LINE CHARGE ("SLC").  The maximum permitted amount that an
        ILEC may charge for SLCs on certain lines was increased. Specifically,
        the ceiling was increased significantly for second and additional
        residential lines, and for multi-line business customers. SLC ceiling
        increases began in July 1997 and will be phased in over a two-year
        period.
 
        - PRESUBSCRIBED INTEREXCHANGE CARRIER CHARGE ("PICC").  The FCC created
        a new PICC access charge rate element. The PICC is a flat-rate, per-line
        charge that is recovered by LECs from IXCs. The charge is designed to
        recover common line revenue not recovered through SLCs. Effective
        January 1, 1998, the maximum permitted interstate PICC charge is $0.53
        per month for primary residential lines and $1.50 per month for second
        and additional residential lines. The initial maximum interstate PICC
        for multi-line businesses are $2.75. The ceilings will be permitted to
        increase over time.
 
        - CARRIER COMMON LINE CHARGE ("CCL").  As the ceilings on the SLCs and
        PICCs increase, the per-minute CCL charge will be eliminated. Until
        then, the CCL will be
 
                                       80
<PAGE>   86
 
        assessed on originating minutes of use. Thus, ILECs will charge lower
        rates for terminating than originating access. In addition, Long-term
        Support ("LTS") payments for universal service will be eliminated from
        the CCL charge.
 
        - LOCAL SWITCHING.  Effective January 1, 1998, ILECs subject to
        price-cap regulation were required to move non-traffic-sensitive ("NTS")
        costs of local switching associated with line ports to common line rate
        elements and recover them through the common line charge discussed
        above. Local switching costs attributable to dedicated trunk ports must
        be moved to the trunking basket and recovered through flat-rate monthly
        charges.
 
        - TRANSPORT.  The "unitary" rate structure option for tandem-switched
        transport will be eliminated effective July 1, 1998. For price cap LECs,
        additional rate structure changes became effective on January 1, 1998,
        which altered the recovery of certain NTS costs of tandem- switching and
        multiplexing and the minutes-of-use assumption employed to determine
        tandem-switched transport prices. Also effective January 1, 1998,
        certain costs currently recovered through the Transport Interconnection
        Charge ("TIC") were reassigned to specified facilities charges. The
        reassignment of tandem costs currently recovered through the TIC to the
        tandem switching charge will be phased in evenly over a three-year
        period. Residual TIC charges will be covered in part through the PICC,
        and price cap reductions will be targeted at the per-minute residual TIC
        until it is eliminated.
 
          In other actions, the FCC clarified that ILECs may not assess
        interstate access charges on the purchasers of unbundled network
        elements or information services providers (including ISPs). Further
        regulatory actions affecting ISPs are being considered in a FCC notice
        of inquiry released on December 24, 1996. The FCC also decided not to
        adopt any regulations governing the provision of terminating access by
        CLECs. ILECs also were ordered to adjust their access charge rate levels
        to reflect contributions to and receipts from the new universal service
        funding mechanisms.
 
          The FCC also announced that it will, in a subsequent Report and Order,
        provide detailed rules for implementing a market-based approach to
        further access charge reform. That process will give ILECs progressively
        greater flexibility in setting rates as competition develops, gradually
        replacing regulation with competition as the primary means of setting
        prices. The FCC also adopted a "prescriptive safeguard" to bring access
        rates to competitive levels in the absence of competition. For all
        services then still subject to price caps and not deregulated in
        response to competition, the FCC required ILECs subject to price caps to
        file Total Service Long Run Incremental Cost ("TSLRIC") cost studies no
        later than February 8, 2001.
 
         This series of decisions is likely to have a significant impact on the
       operations, expenses, pricing and revenue of the Company and costs
       vis-a-vis larger, more efficient carriers such as AT&T, MCI and Sprint.
       Various parties have sought reconsideration or appeal of the FCC's access
       charge rulings and all or part of the order ultimately could be set aside
       or revised. The Company cannot predict the outcome of these proceedings.
 
     UNIVERSAL SERVICE REFORM.  On May 8, 1997, the FCC released an order in its
CC Docket No. 96-45, which reforms the current system of interstate universal
service support and implements the universal service provisions of the
Telecommunications Act. The FCC established a set of policies and rules that
ensure that low-income consumers and consumers that live in rural, insular and
high-cost areas receive a defined set of local telecommunications services at
affordable rates. This is accomplished in part through expansion of direct
consumer subsidy programs and in part by ensuring that rural, small and
high-cost LECs continue to receive universal service subsidy support. The FCC
also created new programs to subsidize connection of eligible schools, libraries
and rural health care providers to telecommunications networks. These programs
will be funded by assessment of eligible revenue of nearly all providers of
interstate telecommunications carriers, including the Company.
                                       81
<PAGE>   87
 
     The Company, like other telecommunications carriers that provide interstate
telecommunications services, will be required to contribute a portion of its
end-user telecommunications revenue to fund universal service programs. These
contributions became due beginning in 1998 for all providers of interstate
telecommunications services. Such contributions are assessed based on
intrastate, interstate and international end user telecommunications revenue.
Contribution factors vary quarterly, and carriers, including the Company, are
billed each month. Contribution factors for the first three quarters of 1998
have been determined by the FCC as follows: first quarter, second quarter and
third quarter factors are 3.19%, 3.14% and 3.14%, respectively, for the high
cost and low income funds (interstate and international end user
telecommunications revenue) and 0.72%, 0.76% and 0.75%, respectively, for the
schools, libraries and rural health funds (intrastate, interstate and
international end user communications revenue). In addition, many state
regulatory agencies have instituted proceedings to revise state universal
support mechanisms to make them consistent with the requirements of the
Telecommunications Act. As a result, the Company will be subject to state, as
well as federal, universal service fund contribution requirements, which will
vary from state to state. Several parties have appealed the FCC's May 8th order,
and these appeals have been consolidated in the U.S. Court of Appeals for the
Fifth Circuit. In addition, a number of telecommunications companies have filed
a petition for a stay with the FCC, which is currently pending.
 
     Pursuant to the Universal Service Order, all carriers were required to
submit a Universal Service Fund worksheet in September 1997. The Company has
filed its Universal Service Fund worksheet. The amounts remitted to the
Universal Service Fund may be billed to the Company's customers. If the Company
does not bill these amounts to its customers, its profit margins may be less
than if it had elected to do so. However, if the Company elects to bill these
amounts to its customers, customers may reduce their use of the Company's
services, or elect to use the services provided by the Company's competitors,
which may have a material adverse effect upon the Company's business, financial
condition, or results of operation. The Company is eligible to qualify as a
recipient of universal service support if it elects to provide facilities-based
service to areas designated for universal service support and if it complies
with federal and state regulatory requirements to be an eligible
telecommunications carrier. The FCC's decisions in CC Docket No. 96-45 could
have a significant impact on future operations of the Company. Significant
portions of the FCC's order have been appealed and are under review by the U.S.
Court of Appeals for the Fifth Circuit. The Company cannot predict the outcome
of these proceedings.
 
     CURRENT COMPANY CERTIFICATIONS.  The Company has received Section 214
authorization from the FCC allowing it to engage in business as a resale and
facilities-based international carrier.
 
STATE REGULATION
 
     Most states require a certification or other authorization to offer local
exchange and long distance intrastate services. These certifications generally
require a showing that the carrier has adequate financial, managerial and
technical resources to offer the proposed services in a manner consistent with
the public interest. In addition to tariff requirements, most states require
that common carriers charge just and reasonable rates and not discriminate among
similarly situated customers. Some states also require the filing of periodic
reports, the payment of various regulatory fees and surcharges, and compliance
with service standards and consumer protection rules. States generally retain
the right to sanction a carrier or to revoke certification if a carrier violates
relevant laws and/or regulations. If any state regulatory agency were to
conclude that the Company is or was providing intrastate services without the
appropriate authority, the agency could initiate enforcement actions, which
could include the imposition of fines, a requirement to disgorge revenues, or
the refusal to grant the regulatory authority necessary for the future provision
of intrastate telecommunications services. The Company holds authority to
provide intrastate interLATA and, where authorized, intraLATA toll service in 49
states. The authority in some states may be limited to resale of long distance
service. The Company is in the process of obtaining intrastate toll authority in
Alaska. The Company has authority to provide competitive local exchange service
in
 
                                       82
<PAGE>   88
 
Massachusetts, New Hampshire and Rhode Island. The Company has applications
pending to provide resold and facilities-based competitive local exchange
services in several other Northeastern and Southeastern states. There is no
industry consensus on what constitutes a "facilities-based" carrier and the FCC
and state regulatory agency definitions vary accordingly. There can be no
assurance that the Company will receive the authorizations it seeks currently or
in the future.
 
     The FCC imposes on entities authorized to provide international
telecommunications service prior approval requirements for "transfers of
control", including pro forma transfers. The Company is also subject to
requirements in certain states to obtain prior approval for, or notify the state
commission of, any transfers of control, sales of assets, corporate
reorganizations, issuances of stock or debt instruments and related
transactions. The Company did not obtain prior approval for its July 1998
corporate reorganization to create a holding company structure whereby Network
Plus Corp. became the holding company of Network Plus, Inc. The Company is in
the process of filing the necessary papers at the FCC and relevant state
commissions seeking nunc pro tunc (retroactive) approval of the transaction on
the grounds that the transaction serves certain important business needs of the
Company and enhances the Company's ability to market and provide services more
efficiently. Although the Company believes that its applications will be
approved in due course, there can be no assurance that the FCC or state
commissions will grant the Company's requests for retroactive approval and/or
will not impose fines or license conditions, commence revocation proceedings or
otherwise exercise their authority to address violations of applicable statutes
and regulations.
 
     The Company believes that most, if not all, states in which it proposes to
operate as a local telecommunications provider will require certification or
other authorization to offer local intrastate services. Many of the states in
which the Company intends to operate are in the process of addressing issues
relating to the regulation of CLECs.
 
     In some states, existing state statutes, regulations or regulatory policy
may preclude some or all forms of local service competition. However, Section
253 of the Telecommunications Act prohibits states and localities from adopting
or imposing any legal requirement that may prohibit, or have the effect of
prohibiting, the ability of any entity to provide any interstate or intrastate
telecommunications service. The FCC has the authority to preempt any such state
or local requirements to the extent necessary to enforce the Telecommunications
Act's open market entry requirements. States and localities may, however,
continue to regulate the provision of intrastate telecommunications services and
require carriers to obtain certificates or licenses before providing service if
such requirements do not constitute prohibited barriers to market entry.
 
     Some states in which the Company operates are considering legislation that
could impede efforts by new entrants in the local services market to compete
effectively with ILECs. For example, some state public utility commissions
("PUCs") are currently considering actions to preserve universal service and
promote the public interest. The actions may impose conditions on the
certificate issued to an operating company that would require it to offer
service on a geographically widespread basis through (i) the construction of
facilities to serve all residents and business customers in such areas, (ii) the
acquisition from other carriers of network facilities required to provide such
service, or (iii) the resale of other carriers' services. The Company believes
that state PUCs have limited authority to impose such requirements under the
Telecommunications Act. The imposition of such conditions by state PUCs,
however, could increase the cost to operating companies of providing local
exchange services, or could otherwise affect the operating companies'
flexibility to offer services. Another state action that impedes efforts by new
entrants to compete in the local exchange services market is the enactment of
state laws that prohibit competition in certain areas of a state. For example,
Section 65-4-201(d) of the Tennessee Code prohibits local exchange
telecommunications competition in areas of Tennessee served by carriers with
fewer than 100,000 access lines within the state. Other states have or may enact
similar provisions; however, to date the FCC has considered Texas and Wyoming
statutory provisions that are virtually identical to the
 
                                       83
<PAGE>   89
 
Tennessee statute, and has preempted both statutes as violative of sec.253(a) of
the Telecommunications Act. A petition for preemption of the Tennessee statute
has been filed at the FCC.
 
     The Company believes that, as the degree of intrastate competition
increases, the states will offer the ILECs increasing pricing flexibility. This
flexibility may present the ILECs with an opportunity to subsidize services that
compete with the Company's services with revenue generated from non-competitive
services, thereby allowing ILECs to offer competitive services at prices below
the cost of providing the service. The Company cannot predict the extent to
which this may occur or its impact on the Company's business.
 
     LOCAL INTERCONNECTION.  The Telecommunications Act imposes a duty upon all
ILECs to negotiate in good faith with potential interconnectors to provide
interconnection to the ILEC networks, exchange local traffic, make unbundled
network elements available and permit resale of most local services. In the
event that negotiations do not succeed, the Company has a right to seek state
PUC arbitration of any unresolved issues. The Company entered into an
interconnection agreement with Bell Atlantic for Massachusetts and is
negotiating interconnection arrangements in a number of states in its targeted
regions. Arbitration decisions involving interconnection arrangements in several
states have been challenged in lawsuits filed in U.S. District Court by the
affected ILECs.
 
     The Company is currently negotiating interconnection agreements with (i)
Bell Atlantic or its affiliates in New Hampshire, New Jersey, New York,
Pennsylvania, Rhode Island, Vermont and Maine; (ii) Southern New England
Telephone or its affiliates in Connecticut; (iii) Bell South or its affiliates
in Georgia, Florida and Tennessee; (iv) GTE or its affiliates in Florida; and
(v) Sprint or its local affiliates in Florida. It is the Company's intention
that by December 31, 1998 it will have successfully negotiated, and have in
effect, interconnection agreements in each of the aforementioned jurisdictions
specifically covering the following elements: (a) reciprocal transport and
termination of local traffic (and related compensation issues); (b) access to
unbundled network elements, including local loops and operations support
systems; (c) resale of local exchange services at wholesale rates (where it does
not currently have such an agreement in place); and (d) local number
portability. The Company may experience difficulty in obtaining timely ILEC
implementation of local interconnection agreements, and there can be no
assurance the Company will offer local services in these areas in accordance
with its projected schedule, if at all. See "Risk Factors -- Lack of
Interconnection and Peering Agreements".
 
     LOCAL GOVERNMENT AUTHORIZATIONS.  If the Company constructs local networks,
it will be required to obtain street use and construction permits and licenses
and/or franchises to install and expand its fiber optic networks using municipal
rights-of-way. In some municipalities the Company may be required to pay license
or franchise fees based on a percentage of gross revenue or on a per linear foot
basis, as well as post performance bonds or letters of credit. There can be no
assurance that the Company will not be required to post bonds in the future. In
many markets, the ILECs do not pay such franchise fees or pay fees that are
substantially less than those that will be required to be paid by the Company.
To the extent that competitors do not pay the same level of fees as the Company,
the Company could be at a competitive disadvantage. However, the
Telecommunications Act provides that any compensation extracted by states and
localities for use of public rights-of-way must be "fair and reasonable",
applied on a "competitively neutral and nondiscriminatory basis" and be
"publicly disclosed" by such government entity. See "Risk Factors -- The
Telecommunications Act and Other Regulation".

EMPLOYEE BENEFIT PLANS
 
  1998 STOCK INCENTIVE PLAN
 
     The Company's 1998 Stock Incentive Plan (the "1998 Incentive Plan") was
adopted by the Company in July 1998. The 1998 Incentive Plan provides for the
grant of stock-based awards to employees, officers and directors of, and
consultants or advisors to, the Company. Under the 1998 Incentive Plan, the
Company may grant options that are intended to qualify as incentive stock
options ("incentive stock options") within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), options not intended to
qualify as incentive stock options ("nonqualified options"), restricted stock
and other stock-based awards. Incentive stock options may be granted only to
employees of the Company. A total of 1,400,000 shares of Common Stock may be
issued upon the exercise of options or other awards granted under the 1998
Incentive Plan. The number of shares with respect to which awards may be granted
to any employee under the 1998 Incentive Plan may not exceed 700,000 during any
calendar year. The exercisability of options or other awards granted under the
1998 Incentive Plan may in certain circumstances be accelerated in connection
with an Acquisition Event (as defined in the 1998 Incentive Plan). Options and
other awards may be granted under the 1998 Incentive Plan at exercise prices
that are equal to, less than or greater than the fair market value of the
Company's Common Stock, and the Board generally retains the right to reprice
outstanding options. The 1998 Incentive Plan expires in June 2008, unless sooner
terminated by the Board. As of July 15, 1998, the Company had granted options to
purchase an aggregate of 741,140 shares of Common Stock under the 1998 Incentive
Plan, including an option to purchase 120,000 shares to Mr. Crowley, an option
to purchase 23,334 shares to Mr. Stanfill, an option to purchase 14,620 shares
to Mr. McConnaughey, an option to purchase 10,045 shares to Mr. Shapiro, an
option to purchase 40,000 shares to Mr. Oyster and an option to purchase 40,000
shares to Mr. Haines. The remainder of the options were granted to approximately
190 employees of, and one consultant to, the Company. These options generally
 
                                       87

become exercisable in four equal annual installments beginning on the first
anniversary of the date of grant, subject in certain cases to accelerated
vesting in connection with an Acquisition Event.
 
  401(k) PLAN
 
     Effective January 1, 1995, the Company adopted the Employee 401(k) and
Profit Sharing Plan (the "401(k) Plan") covering the Company's eligible
employees. Pursuant to the 401(k) Plan, employees may elect to reduce their
current compensation by up to the lesser of 15% of eligible compensation or the
statutorily prescribed annual limit ($10,000 in 1998) and have the amount of
such reduction contributed to the 401(k) Plan. The 401(k) Plan permits, but does
not require, additional contributions to the 401(k) Plan by the Company on
behalf of all participants. The Company contributed $175,000 to the 401(k) Plan
in 1995. No additional contributions have been made by the Company. The 401(k)
Plan is intended to qualify under Section 401 of the Code, so that contributions
by employees or by the Company to the 401(k) Plan, and income earned on plan
contributions, are not taxable to employees until withdrawn, and contributions
by the Company, if any, are deductible by the Company when made.
 
                              CERTAIN TRANSACTIONS
 
     The Company's office space in Quincy, Massachusetts is leased from a trust,
the beneficiaries of which are the stockholders of the Company. The Company
makes monthly rental payments to the trust of $35,900. In each of the years
ending December 31, 1997, 1996 and 1995, the amount paid to the trust was
$431,000. The Company is currently in the process of negotiating an increase in
the rental payments under this lease and expects that, following such increase,
the lease will be on terms no less favorable to the Company than could be
obtained in an arms' length transaction. The Company is also contingently liable
as a guarantor on a bank loan made to the trust. The outstanding balance on the
loan at December 31, 1997 and 1996 was approximately $1.5 million. In addition,
the trust is a guarantor on the Existing Bank Credit Facility. See "Description
of Certain Indebtedness".
 
     On September 2, 1998, the Company paid a dividend in the aggregate amount
of $5.0 million. As a result, $2.5 million was distributed to each of Robert T.
Hale and Robert T. Hale, Jr. Robert T. Hale, Jr., reinvested $1.9 million in the
Company (representing approximately the distribution to him, net of his
estimated tax liability resulting from such dividend) in the form of a long-term
loan to the Company. Interest on such loan will accrue at Fleet's prime rate.
Principal and interest on such loan will be payable 10 days after the redemption
of the Series A Preferred Stock.
 
     In December 1997, the Company's stockholders issued the Company loans
totaling $1,755,000. Interest on the loans accrued at the prevailing prime rate
(8.5% at December 31, 1997) and was payable monthly. There was no required
period for principal repayment. The loans, including accrued interest of
$12,017, were repaid in May 1998. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations".
 
     The Company had a service arrangement with a marketing company, the
controlling stockholders of which include the Company's stockholders. The
marketing company provided services relative to establishing, training and
expanding the Company's sales organization. For the years ending December 31,
1997, 1996 and 1995, the amounts paid to the marketing company were $55,000,
$132,000 and $197,000, respectively. This service arrangement was terminated in
May 1997.

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company's Certificate of Incorporation (the "Charter") authorizes (i)
20,000,000 shares of Common Stock, $.01 par value, and (ii) 1,000,000 shares of
Preferred Stock, $.01 par value, of which 50,000 shares have been designated
13.5% Series A Cumulative Preferred Stock due 2009 and 50,000 shares have been
designated 13.5% Series A1 Cumulative Preferred Stock due 2009. Set forth below
and under "Description of the Series A Preferred Stock" is a description of the
capital stock of the Company.
 
COMMON STOCK
 
     As of July 15, 1998, there were 10,000,000 shares of Common Stock issued
and outstanding and held of record by two stockholders. The holders of Common
Stock are entitled to receive dividends when and as dividends are declared by
the Board of Directors of the Company out of funds legally available therefor,
provided that if any shares of Preferred Stock are at the time outstanding, the
payment of dividends on the Common Stock or other distributions may be subject
to the declaration and payment of full cumulative dividends on outstanding
shares of Preferred Stock. Holders of Common Stock are entitled to one vote per
share on all matters submitted to a vote of the stockholders, including the
election of directors. Upon any liquidation, dissolution or winding up of the
affairs of the Company, whether voluntary or involuntary, any assets remaining
after the satisfaction in full of the prior rights of creditors and the
aggregate liquidation preference of any Preferred Stock (including the Series A
Preferred Stock) then outstanding will be distributed to the holders of Common
Stock ratably in proportion to the number of shares held by them. The Common
Stock is not publicly traded. See "Risk Factors -- Control by Existing
Stockholders; Potential Conflict of Interest; Deadlock; Antitakeover
Provisions".
 
PREFERRED STOCK
 
     Under the Charter, the Board of Directors has the authority to issue up to
1,000,000 shares of Preferred Stock from time to time in one or more series with
such preferences, terms and rights as the Board of Directors may determine
without further action by the stockholders of the Company. Accordingly, the
Board of Directors has the power to establish the provisions, if any, relating
to dividends, voting rights, redemption rates, sinking funds, liquidation
preferences and conversion rights for any series of Preferred Stock issued in
the future. For a description of the Series A Preferred Stock, see "Description
of the Series A Preferred Stock". No other shares of preferred stock have been
issued or are outstanding.
 
     One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
The issuance of shares of the Preferred Stock pursuant to the Board of
Directors' authority described above may adversely affect the rights of the
holders of Common Stock. For example, Preferred Stock issued by the Company may
rank prior to the Common Stock as to dividend rights, liquidation preference or
both, may have full or limited voting rights and may be convertible into shares
of Common Stock. Accordingly, the issuance of shares of Preferred Stock may
discourage bids for the Common Stock or may otherwise adversely affect the
market price of the Common Stock.
 
LIMITATION OF LIABILITY OF DIRECTORS
 
     The Company's Charter eliminates the personal liability of the Company's
directors to the Company or its stockholders for monetary damages for breach of
a director's fiduciary duty to the full extent permitted by the Delaware General
Corporation Law (the "DGCL").
 
                                       90
<PAGE>   96
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Charter provides that the directors and officers of the Company shall
be indemnified by the Company to the fullest extent authorized by Delaware law,
as it now exists or may in the future be amended, against all expenses and
liabilities reasonably incurred in connection with service for or on behalf of
the Company. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the Charter, 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 addition, the Charter
of the Company provides that the directors of the Company will not be personally
liable for monetary damages to the Company for breaches of their fiduciary duty
as directors if they act in good faith and in a manner they reasonably believe
to be in, or not opposed to, the best interests of the Company, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
their conduct was unlawful.
 
     The Company has purchased a general liability insurance policy that covers
certain liabilities of directors and officers of the Company arising out of
claims based on acts and omissions in their capacity as directors and officers.
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
     In the event the Company's Common Stock becomes or may become widely held,
the Board of Directors or the stockholders may adopt certain charter or by-law
provisions that have the effect of discouraging, delaying or making more
difficult a change in control of the Company or preventing the removal of
incumbent directors even if a majority of the Company's stockholders were to
deem such an attempt to be in the best interests of the Company. Such provisions
may include a classified board of directors, limitations in the manner in which
directors are elected and limitations on matters that may be presented at
meetings by stockholders.
 
                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
EXISTING BANK CREDIT FACILITY
 
     The Existing Bank Credit Facility with Fleet provides NPI the ability to
borrow amounts up to $23 million from time to time prior to May 31, 2001. The
Existing Bank Credit Facility is secured by the assets of NPI and includes
certain restrictive covenants, including limitations on the ability of NPI to
incur additional indebtedness, to make loans and advances and to merge or
consolidate. The Existing Bank Credit Facility prohibits the payment by NPI of
dividends to its stockholders other than dividends in amounts necessary to pay
income taxes and related tax preparation costs of the Company's stockholders as
a result of the Company's status as an "S" corporation. The Existing Bank Credit
Facility also contains financial covenants, including minimum gross profits,
operating profits and losses, and minimum capitalization. At July 15, 1998,
there was $2.8 million of outstanding indebtedness under the Existing Bank
Credit Facility. See "Risk Factors -- Holding Company Structure".
 
STOCKHOLDER LOAN
 
     On September 2, 1998, Robert T. Hale, Jr., the Company's President and
Chief Executive Officer, loaned $1.9 million to the Company. This amount
represents a reinvestment in the Company of a $2.5 million dividend distribution
to Robert T. Hale, Jr., net of the estimated tax liability related to such
distribution. Interest on such loan accrues at Fleet's prime rate. Principal and
interest on such loan will be payable 10 days after redemption of the Series A
Preferred Stock. See "Certain Transactions".
 
                                       91

NEW REVOLVING CREDIT FACILITY
 
     The description set forth below does not purport to be complete and is
qualified in its entirety by reference to definitive documentation setting forth
the principal terms and conditions of the New Revolving Credit Facility, which
is available upon request from the Company. See "Risk Factors -- Substantial
Future Capital Requirements; Need for Additional Financing; Substantial
Leverage".
 
     On August 14, 1998, the Company entered into a commitment letter with
Goldman Sachs Credit Partners L.P. for the New Revolving Credit Facility. The
New Revolving Credit Facility is a $60 million facility, concurrent with the
closing of which the Company expects to terminate the Existing Bank Credit
Facility. The New Revolving Credit Facility will have a term of 18 months and
will be secured by the assets of the Company. Under the New Revolving Credit
Facility, up to $60 million will be available, of which $30 million will be
available based upon a percentage of accounts receivable. Interest will be
payable at one percent above the prime rate. The New Revolving Credit Facility
will require the Company to meet, among other things, minimum levels of
revenues, access lines in service and EBITDA. See "Description of Certain
Indebtedness -- New Revolving Credit Facility".
 
     It is contemplated that proceeds from borrowings under the New Credit
Facility will be used to repay and retire the Existing Bank Credit Facility. See
"Management's Discussion and Analysis of Results of Operations -- Liquidity and
Capital Resources".
 
                  DESCRIPTION OF THE SERIES A PREFERRED STOCK
 
     The following is a summary of certain provisions of the Certificate of
Designation and the Series A Preferred Stock. A copy of the Certificate of
Designation and the form of Series A Preferred Stock is available upon request
to the Company at the address set forth under "Available Information". The
following summary of certain provisions of the Certificate of Designation does
not purport to be complete and is subject to, and is qualified in its entirety
by reference to, all the provisions of the Certificate of Designation. The
definitions of certain capitalized terms used but not defined in the following
summary are set forth under "-- Certain Definitions". Other capitalized terms
used but not defined herein and not otherwise defined under "-- Certain
Definitions" are defined in the Certificate of Designation.
 
GENERAL
 
     At the consummation of the Initial Offering, the Company issued 40,000
shares of its 13.5% Series A Cumulative Preferred Stock Due 2009, $0.01 par
value per share. In this Exchange Offer, the Company will offer to exchange one
share of its 13.5% Series A1 Cumulative Preferred Stock Due 2009 for each
outstanding share of its 13.5% Series A Cumulative Preferred Stock Due 2009. The
13.5% Series A Cumulative Preferred Stock Due 2009 and the 13.5% Series A1
Cumulative Preferred Stock Due 2009 are substantially identical in all material
respects (except with respect to certain rights in connection with this Exchange
Offer), and, unless otherwise indicated, both are referred to in this Prospectus
as the "Series A Preferred Stock".
 
RANKING
 
     The Series A Preferred Stock will, with respect to dividend rights and
rights on liquidation, winding-up and dissolution, rank (i) senior to all
classes of common stock and to each other class of Capital Stock of the Company
or series of Preferred Stock of the Company outstanding on the Issue Date and
each other class or series established hereafter by the Board of Directors the
terms of which do not expressly provide that it ranks senior to, or on a parity
with, the Series A Preferred Stock as to dividend rights and rights on
liquidation, winding-up and dissolution of the Company (collectively referred
to, together with all classes of common stock of the Company, as "Junior
Stock"); (ii) on a parity with each class of Capital Stock of the Company or
series of Preferred Stock of the Company established hereafter by the Board of
Directors, the terms of which expressly provide that such class or series will
rank on a parity with the Series A Preferred Stock as to
 
                                       92
<PAGE>   98
 
dividend rights and rights on liquidation, winding-up and dissolution
(collectively referred to as "Parity Stock"); and (iii) junior to each class of
Capital Stock of the Company or series of Preferred Stock of the Company
established hereafter by the Board of Directors, the terms of which expressly
provide that such class or series will rank senior to the Series A Preferred
Stock as to dividend rights and rights upon liquidation, winding-up and
dissolution of the Company (collectively referred to as "Senior Stock").
 
     While any shares of Series A Preferred Stock are outstanding, the Company
may not authorize, create or increase the authorized amount of any class or
series of stock that ranks senior to or on parity with the Series A Preferred
Stock with respect to the payment of dividends or amounts upon liquidation,
dissolution or winding up without the consent of the holders of a majority of
the outstanding shares of Series A Preferred Stock. However, without the consent
of any holder of Series A Preferred Stock, the Company may create additional
classes of stock, increase the authorized number of shares of preferred stock or
issue series of a stock that ranks junior to the Series A Preferred Stock with
respect, in each case, to the payment of dividends and amounts upon liquidation,
dissolution and winding up. See "-- Voting Rights".
 
     All claims of the holders of the Series A Preferred Stock, including
without limitation, claims with respect to dividend payments, redemption
payments, mandatory repurchase payments or rights upon liquidation, winding-up
or dissolution, shall rank junior to the claims of any holders of any debt of
the Company and its Subsidiary and all other creditors of the Company and its
Subsidiary. Substantially all the operations of the Company is conducted through
its Subsidiary and in future will be conducted through one or more of its
subsidiaries. Accordingly, the Company is and will be a holding company with no
assets other than the capital stock of such 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 the Company. Although the Certificate of Designation limits the
incurrence of Debt of the Company and certain of its subsidiaries, such
limitation is subject to a number of significant qualifications. Moreover, the
Certificate of Designation does not impose any limitation on the incurrence of
liabilities that are not considered Debt under the Certificate of Designation.
See "-- Certain Covenants -- Limitation on Debt".
 
DIVIDENDS
 
     The holders of shares of Series A Preferred Stock will be entitled to
receive, when, as and if dividends are declared by the Board of Directors out of
funds of the Company legally available therefor, cumulative preferential
dividends from the Issue Date at a rate per share of 13.5% per annum of the
Specified Amount per share of Series A Preferred Stock, payable quarterly in
arrears on each of March 1, June 1, September 1 and December 1 (each a "Dividend
Payment Date") or, if any such date is not a Business Day, on the next
succeeding Business Day, to the holders of record as of the next preceding
February 15, May 15, August 15 and November 15, respectively. Subject to the
next succeeding sentence, dividends will be payable in cash. If any dividend
(other than any Special Dividends) payable on any Dividend Payment Date on or
before September 1, 2003 is not declared or paid in full in cash on such
Dividend Payment Date, the amount payable as dividends on such Dividend Payment
Date (other than any Special Dividends) that is not paid in cash on such
Dividend Payment Date will be added automatically to the Specified Amount of the
Series A Preferred Stock on such Dividend Payment Date (such dividends being
herein called the "Accumulated Dividends"). The first dividend payment of Series
A Preferred Stock will be payable on December 1, 1998. Dividends payable on the
Series A Preferred Stock will be computed on a basis of the 360-day year
consisting of twelve 30-day months and will be deemed to accrue on a daily
basis.
 
     For a discussion of certain Federal income tax considerations relevant to
the payment of dividends on the Series A Preferred Stock, see "Certain United
States Federal Income Tax Consequences".
 
                                       93
<PAGE>   99
 
     Dividends on the Series A Preferred Stock will accrue whether or not the
Company has earnings or profits, whether or not there are funds legally
available for the payment of such dividends and whether or not dividends are
declared. Dividends will accumulate to the extent they are not paid on the
Dividend Payment Date for the period to which they relate. The Certificate of
Designation will provide that the Company will take all actions required or
permitted under the Delaware General Corporation Law (the "DGCL") to permit the
payment of dividends on the Series A Preferred Stock.
 
     No dividend whatsoever shall be declared or paid upon, or any sum set apart
for the payment of dividends upon, any outstanding share of the Series A
Preferred Stock with respect to any dividend period unless all dividends for all
preceding dividend periods have been added to the Specified Amount (if on or
before September 1, 2003), declared and paid, or declared and a sufficient sum
set apart for the payment of such dividend, upon all outstanding shares of
Series A Preferred Stock.
 
     Except as provided in the next sentence, no dividend will be declared or
paid on any Parity Stock unless full cumulative dividends have been paid (or
deemed paid) on the Series A Preferred Stock for all prior dividend periods. If
accumulated dividends on the Series A Preferred Stock for all prior dividend
periods have not been paid (or deemed paid) in full then any dividend declared
on the Series A Preferred Stock for any dividend period and on any Parity Stock
will be declared ratably in proportion to accrued and unpaid dividends on the
Series A Preferred Stock and such Parity Stock.
 
     The Company will not (i) declare, pay or set apart funds for the payment of
any dividend or other distribution with respect to any Junior Stock or (ii)
redeem, purchase or otherwise acquire for consideration any Junior Stock through
a sinking fund or otherwise, unless (A) all accrued and unpaid dividends with
respect to the Series A Preferred Stock and any Parity Stock at the time such
dividends are payable have been paid (or deemed paid) or funds have been set
apart for payment of such dividends and (B) sufficient funds have been paid or
set apart for the payment of the dividend for the current dividend period with
respect to the Series A Preferred Stock and any Parity Stock.
 
     The Existing Bank Credit Facility prohibits the Company's Subsidiary from
paying cash dividends or making other distributions to the Company so that
unless and until a consent is obtained or such facility is refinanced by a
lender agreeing to such payments or distributions, no cash will be available to
pay dividends on the Series A Preferred Stock. See "Risk Factors -- Holding
Company Structure".
 
OPTIONAL REDEMPTION
 
     Except as set forth below, the Series A Preferred Stock will not be
redeemable at the option of the Company prior to September 1, 2003. Thereafter,
the Series A Preferred Stock will be redeemable, at the Company's option
(subject to the legal availability of funds therefor), 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 the Specified
Amount thereof), plus, without duplication, an amount in cash equal to all
accumulated and unpaid dividends (including Special Dividends and an amount in
cash equal to a prorated dividend for any partial dividend period) (subject to
the rights of holders of record on the relevant record date to receive dividends
due on the relevant Dividend Payment Date), if redeemed during the 12-month
period commencing on September 1 of the years set forth below:

MANDATORY REDEMPTION
 
     As soon as practicable following the closing of a Senior Notes Offering the
net proceeds of which (excluding underwriting or other placement fees and
proceeds placed in escrow at the closing thereof pursuant to the terms of such
offering) received by the Company exceed $100 million, the Company will be
required to redeem (subject to the legal availability of funds therefor) all
outstanding shares of Series A Preferred Stock at a price in cash equal to 108%
of the Specified Amount thereof, plus, without duplication, an amount in cash
equal to all accumulated and unpaid dividends (including Special Dividends and
an amount in cash equal to a prorated dividend for any partial dividend period),
if any, to the date of redemption (subject to the rights of holders of record on
the relevant record date to receive dividends on the relevant Dividend Payment
Date).
 
     In addition, if at any time and from time to time prior to September 1,
2001, the Company consummates one or more Public Equity Offerings, the Company
will be required to apply the first $25 million of net proceeds (excluding
underwriting or other placement fees and calculated on a cumulative basis
beginning with the first such Public Equity Offering) from such Public Equity
Offering or Offerings and one-half of each additional dollar of net proceeds
(excluding underwriting or other placement fees and calculated on a cumulative
basis beginning with the first such Public Equity Offering) in excess of $25
million to redeem the Series A Preferred Stock, at the following redemption
prices (expressed in percentages of the Specified Amount thereof), plus, without
duplication, an amount in cash equal to all accumulated and unpaid dividends
(including Special Dividends and an amount in cash equal to a prorated dividend
for any partial dividend period), if any, to the date of redemption (subject to
the rights of holders of record on the relevant record date to receive dividends
due on the relevant Dividend Payment Date), if redeemed during the period ending
on the dates set forth below:

     In the case of any partial redemption, selection of the Series A Preferred
Stock for redemption will be made on a pro rata basis.
 
     The Company will not be required to make sinking fund payments with respect
to the Series A Preferred Stock. The Certificate of Designation will provide
that the Company will take all actions required or permitted under Delaware law
to permit such redemption.
 
     The Existing Bank Credit Facility prohibits the Company's Subsidiary from
paying cash dividends or making other distributions to the Company. See "Risk
Factors -- Holding Company Structure".
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding-up of
the Company, each holder of Series A Preferred Stock will be entitled to be
paid, out of the assets of the Company available for distribution to
stockholders, an amount equal to the Specified Amount per share of Series A
Preferred Stock held by such holder, plus, without duplication, an amount in
cash equal to all accumulated and unpaid dividends thereon to the date fixed for
liquidation, dissolution or winding-up before any distribution is made on any
Junior Stock, including the Common Stock. If, upon any voluntary or involuntary
liquidation, dissolution or winding-up of the Company, the amounts payable with
respect to the Series A Preferred Stock and all other Parity Stock are not paid
in full, the holders of the Series A Preferred Stock and the Parity Stock will
share equally and ratably in any distribution of assets of the Company in
proportion to the full liquidation preference and
 
                                       95
<PAGE>   101
 
accumulated and unpaid dividends to which each is entitled. After payment of the
full amount of the liquidation preference and accumulated and unpaid dividends
to which they are entitled, the holders of shares of Series A Preferred Stock
will not be entitled to any further participation in any distribution of assets
of the Company. However, neither the sale, conveyance, exchange or transfer (for
cash, shares of stock, securities or other consideration) of all or
substantially all the property or assets of the Company nor the consolidation or
merger of the Company with one or more entities shall be deemed to be a
liquidation, dissolution or winding-up of the Company. The liquidation
preference of the Series A Preferred Stock will be $1,000 per share.
 
     The Certificate of Designation will not contain any provision requiring
funds to be set aside to protect the liquidation preference of the Series A
Preferred Stock, although such liquidation preference will be substantially in
excess of the par value of such shares of Series A Preferred Stock.
 
VOTING RIGHTS
 
     The holders of Series A Preferred Stock, except as otherwise required under
Delaware law or as provided in the Certificate of Designation, shall not be
entitled or permitted to vote on any matter required or permitted to be voted
upon by the stockholders of the Company.
 
     The Certificate of Designation will provide that if (i) after September 1,
2003, dividends on the Series A Preferred Stock are in arrears and unpaid for
six or more dividend periods (whether or not consecutive); (ii) the Company
fails to redeem the Series A Preferred Stock on September 1, 2009, or fails to
otherwise discharge any redemption obligation with respect to the Series A
Preferred Stock; (iii) the Company fails to make an Offer to Purchase if such
offer is required by the provisions of the covenant described under "-- Certain
Covenants -- Change of Control", (iv) a breach or violation of any of the other
provisions described under the caption "-- Certain Covenants" occurs and the
breach or violation continues for a period of 60 days or more after the Company
receives notice thereof specifying the default from the holders of at least 25%
of the shares of Series A Preferred Stock then outstanding; or (v) the Company
fails to pay at final maturity (giving effect to any applicable grace period)
the principal amount of any Debt of the Company or any Significant Subsidiary or
the final maturity of any such Debt is accelerated because of a default and the
total amount of such Debt unpaid or accelerated exceeds $10 million and such
nonpayment continues, or such acceleration is not rescinded or waived, within 10
days, then the holders of the outstanding shares of Series A Preferred Stock,
voting together as a single class, will be entitled to elect to serve on the
Board of Directors the lesser of (x) two additional members to the Board of
Directors or (y) that number of directors constituting 25% of the members of the
Board of Directors, and the number of members of the Board of Directors will be
immediately and automatically increased by such number. Such voting rights of
the Series A Preferred Stock will continue until such time as, in the case of a
dividend default, all dividends in arrears on the Series A Preferred Stock are
paid in full in cash (or, if prior to September 1, 2003, in shares of Series A
Preferred Stock) and, in all other cases, any failure, breach or default giving
rise to such voting rights is remedied or waived by the holders of a majority of
the shares of Series A Preferred Stock then outstanding, at which time the term
of any directors elected pursuant to the provisions of this paragraph (subject
to the right of holders of any other preferred stock to elect such directors)
shall terminate. Each such event described in clauses (i) through (v) above is
referred to herein as a "Voting Rights Triggering Event".
 
     The Certificate of Designation also will provide that the Company will not
authorize any class of Senior Stock without the affirmative vote or consent of
holders of a majority of the shares of Series A Preferred Stock then
outstanding, voting or consenting, as the case may be, as one class. In
addition, the Certificate of Designation will provide that the Company may not
authorize the issuance of any additional shares of Series A Preferred Stock
without the affirmative vote or consent of the holders of a majority of the then
outstanding shares of Series A Preferred Stock, voting or consenting, as the
case may be, as one class. The Certificate of Designation will also provide
that,
                                       96
<PAGE>   102
 
except as set forth above, (a) the creation, authorization or issuance of any
shares of Junior Stock or Parity Stock, including the designation of a series
thereof within the existing class of Series A Preferred Stock, or (b) the
increase or decrease in the amount of authorized Capital Stock of any class,
including any preferred stock, shall not require the consent of the holders of
Series A Preferred Stock and shall not be deemed to affect adversely the rights,
preferences, privileges or voting rights of shares of Series A Preferred Stock.
 
REGISTRATION COVENANT; EXCHANGE OFFER
 
     The Company has agreed pursuant to the Registration Agreement, for the
benefit of the Holders of the Series A Preferred Stock, (i) to file with the
Commission, within 90 days following the closing of the Initial Offering (the
"Closing"), a registration statement (the "Exchange Offer Registration
Statement") with respect to the Exchange Offer and (ii) to use its reasonable
best efforts to cause the Exchange Offer Registration Statement to become
effective as soon as practicable thereafter. The Company has further agreed to
commence the Exchange Offer promptly after the Exchange Offer Registration
Statement has become effective, hold the offer open for at least 30 days, and
exchange New Preferred Shares for all Original Preferred Shares validly tendered
and not withdrawn before the expiration of the Exchange Offer. The New Preferred
Shares are being offered in this Exchange Offer to satisfy the obligations of
the Company under the Registration Agreement.
 
     Under existing Commission interpretations, the New Preferred Shares would
in general be freely transferable after the Exchange Offer without further
registration under the Securities Act, except that broker-dealers
("Participating Broker-Dealers") receiving New Preferred Shares in the Exchange
Offer will be subject to a prospectus delivery requirement with respect to
resale of those New Preferred Shares. The Commission has taken the position that
Participating Broker-Dealers may fulfill their prospectus delivery requirements
with respect to the New Preferred Shares (other than a resale of any unsold
allotment from the Initial Offering) by delivery of the prospectus contained in
the Exchange Offer Registration Statement. Under the Registration Agreement, the
Company is required to allow Participating Broker-Dealers and other persons, if
any, subject to similar prospectus delivery requirements to use the prospectus
contained in the Exchange Offer Registration Statement in connection with the
resale of such New Preferred Shares. The Exchange Offer Registration Statement
will be kept effective for a period of up to 90 days after the Exchange Offer
has been consummated in order to permit resales of New Preferred Shares acquired
by broker-dealers in after-market transactions. Each Holder of the Original
Preferred Shares, (other than certain specified Holders) who wishes to exchange
such Original Preferred Shares for New Preferred Shares in the Exchange Offer
will be required to represent that any New Preferred Shares to be received by it
will be acquired in the ordinary course of its business, that at the time of the
commencement of the Exchange Offer it has no arrangement with any person to
participate in the distribution (within the meaning of the Securities Act) of
the New Preferred Shares and that it is not an Affiliate of the Company.
 
     However, if on or before the date of consummation of the Exchange Offer the
existing Commission interpretations are changed such that the New Preferred
Shares would not in general be freely transferable on such date, the Company
will, in lieu of effecting registration of New Preferred Shares, use its
reasonable best efforts to cause a registration statement under the Securities
Act relating to a shelf registration of the Original Preferred Shares for resale
by Holders (the "Resale Registration") to become effective and to remain
effective for a period of up to two years after the Closing. The Company will,
in the event of the Resale Registration, provide to the Holders of the Original
Preferred Shares copies of the prospectus that is a part of the registration
statement filed in connection with the Resale Registration, notify such Holders
when the Resale Registration for the Original Preferred Shares has become
effective and take certain other actions as are required to permit unrestricted
resales of the Original Preferred Shares. Use of the Resale Registration
registration statement by Holders will be subject to certain Company "black-out"
rights and customary information delivery requirements. A Holder of Original
Preferred Shares that sells
 
                                       97
<PAGE>   103
 
such Original Preferred Shares pursuant to the Resale Registration generally
would be required to be named as a selling securityholder in the related
prospectus and to deliver a prospectus to purchasers, will be subject to certain
of the civil liability provisions under the Securities Act in connection with
such sales and will be bound by the provisions of the Registration Agreement
that are applicable to such Holder (including certain indemnification
obligations).
 
     In the event that (i) the Company has not filed the registration statement
relating to the Exchange Offer (or, if applicable, the Resale Registration)
within 90 days following the Closing, (ii) such registration statement (or, if
applicable, the Resale Registration) has not become effective within 150 days
following the Closing, (iii) the Exchange Offer has not been consummated within
180 days following the Closing or (iv) any registration statement required by
the Registration Agreement is filed and declared effective but shall thereafter
cease to be effective (except as specifically permitted therein) without being
succeeded immediately by an additional registration statement filed and declared
effective (any such event referred to in clauses (i) through (iv), a
"Registration Default"), then dividends will accumulate (in addition to the
stated dividend on the Series A Preferred Stock) at the rate of 0.5% per annum
on the Specified Amount, for the period from the occurrence of the Registration
Default until such time as no Registration Default is in effect. Such additional
dividends (the "Special Dividends") will be payable in cash on each regular
dividend payment date. For each 90-day period that the Registration Default
continues, the per annum rate of such Special Dividends will increase by an
additional 0.25%, provided that such rate shall in no event exceed 1.0% per
annum in the aggregate. Special Dividends, if any, will be computed on the basis
of a 365 or 366 day year, as the case may be, and the number of days actually
elapsed.
 
     The summary herein of certain provisions of the Registration Agreement does
not purport to be complete and is subject to, and is qualified in its entirety
by reference to, all the provisions of the Registration Agreement, a copy of
which will be available upon request to the Company.
 
COVENANTS
 
     The Certificate of Designation contains, among others, the following
covenants:
 
  LIMITATION ON DEBT
 
     (a) The Company may not, and may not permit any Restricted Subsidiary of
the Company to, Incur any Debt unless the ratio of (i) the aggregate
consolidated principal amount of Debt of the Company and its Restricted
Subsidiaries outstanding as of the most recent available quarterly or annual
balance sheet, after giving pro forma effect to the Incurrence of such Debt and
any other Debt Incurred since such balance sheet date and the receipt and
application of the proceeds thereof to (ii) Consolidated Cash Flow Available for
Fixed Charges for the four full fiscal quarters next preceding the Incurrence of
such Debt for which consolidated financial statements are available, determined
on a pro forma basis as if any such Debt had been Incurred at the beginning of
such four fiscal quarters, would be less than 7.0 to 1 for such four-quarter
periods ending on or prior to September 1, 2000, and 5.0 to 1 for such periods
ending thereafter.
 
     (b) Notwithstanding the foregoing paragraph (a), the Company and any
Restricted Subsidiary (except as specified below) may incur any or all of the
following:
 
          (i) Debt outstanding on the Issue Date;
 
          (ii) Debt under any Bank Credit Agreement;
 
          (iii) Purchase Money Debt Incurred to finance the construction,
     acquisition, development, design, installation, integration, transportation

     Incurred pursuant to clause (vi) of this paragraph (b) in respect of Debt
     Incurred
 
                                       98
<PAGE>   104
 
     pursuant to this clause (iii), has an aggregate principal amount at the
     time of Incurrence, not in excess of $100 million at any time outstanding;
 
          (iv) Senior Notes the offering of which, together with any other
     outstanding Debt Incurred pursuant to this clause (iv), resulted in net
     proceeds (excluding underwriting or other placement fees and proceeds
     placed in escrow at the closing thereof pursuant to the terms of such
     offering) to the Company, not in excess of $100 million;
 
          (v) Debt owed by the Company to any Restricted Subsidiary of the
     Company or Debt owed by a Restricted Subsidiary of the Company to the
     Company or a Restricted Subsidiary of the Company; provided, however, that
     upon either (x) the transfer or other disposition by such Restricted
     Subsidiary or the Company of any Debt so permitted to a Person other than
     the Company or another Restricted Subsidiary of the Company or (y) the
     issuance (other than directors' qualifying shares), sale, lease, transfer
     or other disposition of shares of Capital Stock (including by consolidation
     or merger) of such Restricted Subsidiary to a Person other than the Company
     or another such Restricted Subsidiary, the provisions of this clause (v)
     shall no longer be applicable to such Debt and such Debt shall be deemed to
     have been Incurred at the time of such transfer or other disposition;
 
          (vi) Debt Incurred to renew, extend, refinance or refund (each, a
     "refinancing") (A) Debt outstanding on the Issue Date, (B) Debt Incurred
     pursuant to paragraph (a) of this covenant or (C) Debt Incurred pursuant to
     clause (iii) of this paragraph (b), in each case in an aggregate principal
     amount not to exceed the aggregate principal amount of and accrued interest
     on the Debt so refinanced plus the amount of any premium required to be
     paid in connection with such refinancing pursuant to the terms of the Debt
     so refinanced or the amount of any premium reasonably determined by the
     Company as necessary to accomplish such refinancing by means of a tender
     offer or privately negotiated repurchase, plus the amount of expenses of
     the Company incurred in connection with such refinancing; provided,
     however, that the refinancing Debt by its terms, or by the terms of any
     agreement or instrument pursuant to which such Debt is issued, (x) does not
     provide for payments of principal of such Debt at the stated maturity
     thereof or by way of a sinking fund applicable thereto or by way of any
     mandatory redemption, defeasance, retirement or repurchase thereof by the
     Company (including any redemption, retirement or repurchase which is
     contingent upon events or circumstances, but excluding any retirement
     required by virtue of acceleration of such Debt upon any event of default
     thereunder), in each case prior to the time the same are required by the
     terms of the Debt being refinanced and (y) does not permit redemption or
     other retirement (including pursuant to an offer to purchase made by the
     Company) of such debt at the option of the holder thereof prior to the
     final stated maturity of the Debt being refinanced, other than a redemption
     or other retirement at the option of the holder of such Debt (including
     pursuant to an offer to purchase made by the Company) which is conditioned
     upon a change substantially similar to those described under "-- Change of
     Control" or which is pursuant to provisions substantially similar to those
     in the covenant described under "-- Limitation on Asset Dispositions";
 
          (vii) Debt consisting of Permitted Interest Rate or Currency
     Protection Agreements;
 
          (viii) Debt consisting of performance and other similar bonds and
     reimbursement obligations Incurred in the ordinary course of business
     securing the performance of contractual, franchise or license obligations
     of the Company or a Restricted Subsidiary, or in respect of a letter of
     credit obtained to secure such performance;
 
          (ix) Debt of the Company to Robert T. Hale, Jr. in an original
     principal amount at the time of issuance not to exceed $2 million;
     provided, however, that no payment of principal on such Debt may be made
     prior to the redemption of the Series A Preferred Stock and the payment in
     full of all accumulated dividends on the Series A Preferred Stock; and
 
                                       99
<PAGE>   105
 
          (x) Debt of the Company or any Restricted Subsidiary not otherwise
     permitted to be Incurred pursuant to clauses (i) through (viii) above,
     which, together with any other outstanding Debt Incurred pursuant to this
     clause (x), has an aggregate principal amount or, in the case of Debt
     issued at a discount, an accreted amount (determined in accordance with
     generally accepted accounting principles) at the time of Incurrence, not in
     excess of $10 million at any time outstanding.
 
     Notwithstanding any other provision of this "Limitation on Debt" covenant,
the maximum amount of Debt that the Company or a Restricted Subsidiary may Incur
pursuant to this "Limitation on Debt" covenant shall not be deemed to be
exceeded, with respect to any outstanding Debt, due solely to the result of
fluctuations in exchange rates of currencies.
 
     For purposes of determining compliance with this "Limitation on Debt"
covenant, in the event that an item of Debt meets the criteria of more than one
of the types of Debt the Company is permitted to incur pursuant to the foregoing
clauses (i) through (x), the Company shall have the right, in its sole
discretion, to classify such item of Debt and shall only be required to include
the amount and type of such Debt under the clause permitting the Debt as so
classified. For purposes of determining any particular amount of Debt under such
covenant, Guarantees or Liens with respect to letters of credit supporting Debt
otherwise included in the determination of a particular amount shall not be
included.
 
  LIMITATION ON RESTRICTED PAYMENTS
 
     The Company (i) may not, directly or indirectly, declare or pay any
dividend, or make any distribution, in respect of any Junior Stock or to the
holders thereof (in their capacity as such), excluding any dividends or
distributions payable solely in shares of Junior Stock (other than Disqualified
Stock) or in options, warrants or other rights to acquire Junior Stock (other
than Disqualified Stock); (ii) may not, and may not permit any Restricted
Subsidiary to, purchase, redeem, or otherwise retire or acquire for value (a)
any Junior Stock of the Company or any Related Person of the Company or (b) any
options, warrants or rights to purchase or acquire shares of Junior Stock of the
Company or any Related Person of the Company or any securities convertible or
exchangeable into shares of Capital Stock of the Company or any Related Person
of the Company; and (iii) may not make, or permit any Restricted Subsidiary to
make, any Investment in, or payment on a Guarantee of any obligation of, any
Person, other than the Company or a Restricted Subsidiary of the Company, except
for Permitted Investments (each of clauses (i) through (iii) being a "Restricted
Payment") if: (1) any accrued and payable dividends (including dividends for the
then current dividend period) with respect to the Series A Preferred Stock or
any Parity Stock have not been paid (or deemed paid) in full and funds for such
payment have not been set apart shall have occurred and is continuing; or (2)
upon giving effect to such Restricted Payment, the Company could not Incur at
least $1.00 of additional Debt pursuant to the covenant described in paragraph
(a) of "-- Limitation on Debt" above; or (3) upon giving effect to such
Restricted Payment, the aggregate amount of all Restricted Payments from the
Issue Date exceeds the sum of: (a) (x) Consolidated Cash Flow Available for
Fixed Charges since the end of the last full fiscal quarter prior to the Issue
Date through the last day of the last full fiscal quarter ending immediately
preceding the date of such Restricted Payment (the "Calculation Period") minus
(y) 1.5 times Consolidated Interest Expense for the Calculation Period; plus (b)
the aggregate Net Cash Proceeds received by the Company from the issuance or
sale of its Junior 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 a trust
established by the Company or any of its Subsidiaries for the benefit of their
employees); plus (c) the amount by which Debt 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 Debt of the
Company convertible or exchangeable for Junior Stock (other than Disqualified
Stock) of the Company (less the amount of any cash, or the fair
 
                                       100
<PAGE>   106
 
value of any property, distributed by the Company upon such conversion or
exchange); plus (d) $5 million.
 
     Notwithstanding the foregoing, (i) the Company may pay any dividend on
Capital Stock of any class within 60 days after the declaration thereof if, on
the date when the dividend was declared, the Company could have paid such
dividend in accordance with the foregoing provisions; (ii) the Company may
repurchase any shares of its Common Stock or options to acquire its Common Stock
from Persons who are currently or were formerly directors, officers or employees
of the Company or any Restricted Subsidiary, provided that the aggregate amount
of all such repurchases made pursuant to this clause (ii) shall not exceed (a)
$1 million in any calendar year and (b) $5 million in the aggregate; (iii) the
Company and its Restricted Subsidiaries may refinance any Debt otherwise
permitted by clause (vi) of paragraph (b) under "-- Limitation on Debt" above;
(iv) the Company and its Restricted Subsidiaries may retire or repurchase any

the Company in exchange for, or out of the proceeds of the substantially
concurrent sale (other than to a Restricted Subsidiary of the Company) of,
Junior Stock (other than Disqualified Stock) of the Company; and (v) the Company
may pay the dividend of $5 million declared on July 15, 1998. If the Company
makes a Restricted Payment which, at the time of the making of such Restricted
Payment, would in the good faith determination of the Company be permitted under
the Certificate of Designation, such Restricted Payment shall be deemed to have
been made in compliance with the Certificate of Designation notwithstanding any
subsequent adjustments made in good faith to the Company financial statements
affecting Consolidated Cash Flow Available for Fixed Charges or Consolidated
Interest Expense for any period.
 
  LIMITATION ON ASSET DISPOSITIONS
 
     The Company may not, and may not permit any Restricted Subsidiary to, make
any Asset Disposition in one or more related transactions occurring within any
12-month period unless: (i) the Company or the Restricted Subsidiary, as the
case may be, receives consideration for such disposition at least equal to the
fair market value for the assets sold or disposed of as determined by management
of the Company in good faith, which determination shall be conclusive; (ii) at
least 75% of the consideration for such disposition consists of (1) cash or
readily marketable cash equivalents or the assumption of Debt of the Company or
of the Restricted Subsidiary and release from all liability on the Debt assumed;
(2) Telecommunications Assets; or (3) shares of publicly-traded Voting Stock of
any Person engaged in the Telecommunications Business in the United States; and
(iii) all Net Available Proceeds, less any amounts invested within 365 days of
such disposition in new Telecommunications Assets, are applied within 365 days
of such disposition (1) first, to the permanent repayment or reduction of Debt
(other than Disqualified Stock) of the Company or Debt (other than Disqualified
Stock) of a Restricted Subsidiary of the Company, to the extent permitted under
the terms thereof and (2) second, to the extent of remaining Net Available
Proceeds, to make an Offer to Purchase outstanding shares of Series A Preferred
Stock at 100% of the Specified Amount thereof plus, without duplication, an
amount in cash equal to all accumulated and unpaid dividends (including Special
Dividends and an amount in cash equal to a prorated dividend for any partial
dividend period), if any, to the date of purchase (subject to the rights of
holders of record on the relevant record date to receive dividends due on the
relevant dividend payment date), and, to the extent required by the terms
thereof, any other Parity Stock of the Company at a price no greater than 100%
of the liquidation preference thereof plus accumulated dividends to the date of
purchase. To the extent any Net Available Proceeds remain after such uses, the
Company and its Restricted Subsidiaries may use such amounts for any purposes
not prohibited by the Certificate of Designation. Notwithstanding the foregoing,
these provisions shall not apply to any Asset Disposition which constitutes a
transfer, conveyance, sale, lease or other disposition of all or substantially
all the Company's properties or assets as described under "-- Mergers,
Consolidations and Certain Sales of Assets".

  TRANSACTIONS WITH AFFILIATES AND RELATED PERSONS
 
     The Company may not, and may not permit any Restricted Subsidiary of the
Company to, enter into any transaction (or series of related transactions) with
an Affiliate or Related Person of the Company (other than the Company or a
Restricted Subsidiary of the Company), including any Investment, either directly
or indirectly, unless such transaction is on terms no less favorable to the
Company or such Restricted Subsidiary than those that could be obtained in a
comparable arm's-length transaction with an entity that is not an Affiliate or
Related Person and is in the best interests of such Company or such Restricted
Subsidiary. For any transaction that involves in excess of $1 million but less
than or equal to $5 million, the Chief Executive Officer of the Company or a
majority of the disinterested members of the Board of Directors of the Company
shall determine that the transaction satisfies the above criteria. For any
transaction that involves in excess of $5 million but less than or equal to $10
million, a majority of the disinterested members of the Board of Directors of
the Company shall determine that the transaction satisfies the above criteria.
For any transaction that involves in excess of $10 million, the Company shall
also obtain an opinion from a nationally recognized investment banking or
accounting firm or another nationally recognized expert with experience in
appraising the terms and conditions, taken as a whole, of the type of
transaction (or series of related transactions) for which the opinion is
required stating that such transaction (or series of related transactions) is on
terms and conditions, taken as a whole, no less favorable to the Company or such
Restricted Subsidiary than those that could be obtained in a comparable arm's-
length transaction with an entity that is not an Affiliate or Related Person of
the Company, which opinion shall be available for inspection by holders of
Series A Preferred Stock at the Company's offices. This covenant shall not apply
to Investments by an Affiliate or a Related Person of the Company in the Capital
Stock (other than Disqualified Stock) of the Company or any Restricted
Subsidiary of the Company.
 
  CHANGE OF CONTROL
 
     The Certificate of Designation will provide that, within 30 days of the
occurrence of a Change of Control, the Company shall make an Offer to Purchase
all outstanding shares of Series A Preferred Stock at a purchase price equal to
101% of the liquidation preference thereof plus accumulated and unpaid
dividends, if any, to the date of purchase (subject to the rights of holders of
record on the relevant record date to receive dividends due on the relevant
dividend payment date).
 
     A "Change of Control" will be deemed to have occurred at such time as
either (a) any Person or any Persons acting together (other than Permitted
Holders or an underwriter engaged in a firm commitment underwriting on behalf of
the Company) that would constitute a "group" (a "Group") for purposes of Section
13(d) of the Exchange Act, or any successor provision thereto, shall
beneficially own (within the meaning of Rule 13d-3 under the Exchange Act, or
any successor provision thereto) more than 50% of the aggregate voting power of
all classes of Voting Stock of the Company or (b) during any period of two
consecutive years, individuals who at the beginning of such period constituted
the Board of Directors (together with any new directors whose election by the
Board of Directors or whose nomination by the Board of Directors for election by
the Company's stockholders was approved by a vote of at least a majority of the
members of the Board of Directors then in office who either were members of the
Board of Directors at the beginning of such period or whose election or
nomination for election was previously so approved) cease for any reason to
constitute a majority of the members of the Board of Directors then in office.
 
     Except as described above with respect to a Change of Control, the
Certificate of Designation does not contain provisions that permit the Holders
of the Series A Preferred Stock to require that the Company repurchase or redeem
the Series A Preferred Stock in the event of a takeover, recapitalization or
similar restructuring.
 
     The Company does not currently have adequate financial resources to effect
a repurchase of the Series A Preferred Stock upon a Change of Control and there
can be no assurance that the
 
                                       102
<PAGE>   108
 
Company will have such resources in the future. The inability of the Company to
repurchase the Series A Preferred Stock upon acceptance of the Offer to Purchase
made following a Change of Control would constitute a Voting Rights Triggering
Event.
 
     In addition, there may be restrictions contained in instruments evidencing
Debt incurred by the Company or its Restricted Subsidiaries permitted under the
Certificate of Designation which restrict or prohibit the ability of the Company
to effect any repurchase required under the Certificate of Designation in
connection with a Change of Control.
 
     In the event that the Company makes an Offer to Purchase the Series A
Preferred Stock, the Company intends to comply with any applicable securities
laws and regulations, including any applicable requirements of Section 14(e) of,
and Rule 13e-4 and Rule 14e-1 under, the Exchange Act.
 
  PROVISION OF FINANCIAL INFORMATION
 
     The Company has agreed that, for so long as any Series A Preferred Stock
remains outstanding, it will furnish to the holders of the Series A Preferred
Stock and to securities analysts and prospective investors, upon their request,
the information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act. In addition, prior to the effectiveness of the Exchange Offer
Registration Statement, the Company will furnish to the holders of the Series A
Preferred Stock the quarterly and annual financial statements and related notes
and an accompanying Management's Discussion and Analysis of Financial Condition
and Results of Operations in the format that would be required to be included in
the Company's periodic reports filed with the Commission if the Company were
required to file such reports with the Commission. The Company will furnish such
information to the holders of the Series A Preferred Stock within 15 days after
the date on which the Company would have been required to file the same with the
Commission. Following the effectiveness of the Exchange Offer Registration
Statement (or earlier if the Company becomes obligated to file reports with the
Commission), the Company will furnish to the holders of the Series A Preferred
Stock within 15 days after it files them with the Commission copies of the
annual and quarterly reports and the information, documents, and other reports
that the Company is required to file with the Commission pursuant to Section
13(a) or 15(d) of the Exchange Act ("SEC Reports"). In the event the Company
shall cease to be required to file SEC Reports pursuant to the Exchange Act, the
Company will nevertheless continue to file such reports with the Commission
(unless the Commission will not accept such a filing) and furnish such reports
to the holders of Series A Preferred Stock. The Company will make copies of the
SEC Reports available to investors who request them in writing.
 
MERGERS, CONSOLIDATIONS AND CERTAIN SALES OF ASSETS
 
     The Company may not, in a single transaction or a series of related
transactions, (i) consolidate with or merge into any other Person or permit any
other Person to consolidate with or merge into the Company (other than the
consolidation or merger of a Restricted Subsidiary organized under the laws of a
State of the United States into the Company), or (ii) directly or indirectly,
transfer, sell, lease or otherwise dispose of all or substantially all its
assets (determined on a consolidated basis for the Company and its Restricted
Subsidiaries taken as a whole), unless: (1) in a transaction in which the
Company does not survive or in which the Company sells, leases or otherwise
disposes of all or substantially all its assets to any other Person, the
successor entity to the Company is organized under the laws of the United States
of America or any State thereof or the District of Columbia and the Series A
Preferred Stock shall be converted into or exchanged for and shall become shares
of such successor entity, having in respect of such successor entity the same
powers, preferences and relative participating, optional or other special rights
and the qualifications, limitations or restrictions thereon, that the Series A
Preferred Stock had immediately prior to such transaction; (2) immediately after
giving pro forma effect to such transaction as if such transaction had occurred
at the beginning of the last full fiscal quarter immediately prior to the
consummation of
                                       103
<PAGE>   109
 
such transaction with the appropriate adjustments with respect to the
transaction being included in such pro forma calculation and treating any Debt
which becomes an obligation of the Company or a Subsidiary as a result of such
transaction as having been Incurred by the Company or such Subsidiary at the
time of the transaction, no Voting Rights Triggering Event, and no event that
after the giving of notice or lapse of time or both would become a Voting Rights
Triggering Event, shall have occurred and be continuing; (3) immediately after
giving effect to such transaction, the Consolidated Net Worth of the Company (or
the successor entity to the Company) is equal to or greater than that of the
Company immediately prior to the transaction; (4) immediately after giving
effect to such transaction, the Company (or the successor entity to the Company)
would be able to incur an additional $1.00 of Debt under paragraph (a) of the
Covenant described under "-- Limitation on Debt" above; and (5) the Company has
caused to be delivered to the holders of the Series A Preferred Stock an Opinion
of Counsel to the effect that the holders of the Series A Preferred Stock will
not recognize gain or loss for Federal income tax purposes as a result of such
transaction.
 
     In the event of any transaction (other than a lease) described in and
complying with the immediately preceding paragraph in which the Company is not
the surviving person and the surviving person complies with clause (1) of the
preceding paragraph, such surviving person shall succeed to, and be substituted
for, and may exercise every right and power of, the Company, and the Company
will be discharged from its obligations under the Series A Preferred Stock and
the Certificate of Designation; provided that solely for the purpose of
calculating amounts described in clause (3) under the covenant described under
"Covenant -- Limitations on Restricted Payments", any such surviving person
shall only be deemed to have succeeded to and be substituted for the Company
with respect to the period subsequent to the effective time of such transaction,
and the Company (before giving effect to such transaction) shall be deemed to be
the "Company" for such purposes for all prior periods.
 
     The meaning of the phrase "all or substantially all" as used above varies
according to the facts and circumstances of the subject transaction, has no
clearly established meaning under relevant law and is subject to judicial
interpretation. Accordingly, in certain circumstances, there may be a degree of
uncertainty in ascertaining whether a particular transaction would involve a
disposition of "all or substantially all" the assets of the Company, and
therefore it may be unclear whether the foregoing provisions are applicable.
 
CERTAIN DEFINITIONS
 
     Set forth below is a summary of certain of the defined terms used in the
Certificate of Designation. Reference is made to the Certificate of Designation
for the full definition of all such terms, as well as any other terms used

outstanding prior to, such merger, consolidation or acquisition.
 
     "Affiliate" of any Person means any other Person directly or indirectly
controlling or controlled by or under direct or indirect common control with
such Person. For the purposes of this definition, "control" when used with
respect to any Person means the power to direct the management and policies of

securities, by contract or otherwise; and the terms "controlling" and
"controlled" have meanings correlative to the foregoing.
 
     "Asset Disposition" by any Person means any transfer, conveyance, sale,
lease or other disposition by such Person or any of its Restricted Subsidiaries

Person, but
                                       104
<PAGE>   110
 
excluding a disposition by a Restricted Subsidiary of such Person to such Person
or a Wholly Owned Restricted Subsidiary of such Person or by such Person to a

Stock or other ownership interests of a Restricted Subsidiary of such Person
(other than pursuant to a transaction in compliance with the covenant described
under "-- Mergers, Consolidations and Certain Sales of Assets" above), (ii)

Subsidiaries representing a division or line of business (other than as part of

connection with such refinancing pursuant to the terms of any credit agreement
or Permitted Receivables Facility so refinanced plus the amount of expenses
incurred in connection with such refinancing, does not exceed the aggregate

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following general discussion summarizes certain U.S. federal income tax
consequences of the purchase, ownership and disposition of the Series A
Preferred Stock. This discussion only deals with persons that hold shares of
Series A Preferred Stock as capital assets within the meaning of Section 1221 of
the Code, and that purchase the Original Preferred Shares for cash at original
issue. This discussion does not address the U.S. federal income tax consequences
that may be relevant to a particular holder subject to special treatment under
certain U.S. federal income tax laws, such as dealers in securities or foreign
currency, banks, trusts, insurance companies, tax-exempt organizations, persons
who are not U.S. Holders (as defined below), persons that hold Series A
Preferred Stock as part of a straddle, hedge, synthetic security, constructive
sale or conversion transaction, persons that have a functional currency other
than the U.S. dollar and investors in pass-through entities.
 
     This discussion is based on the Code, the final, temporary and proposed
Treasury regulations promulgated thereunder, administrative pronouncements and
judicial decisions, all as in effect on the date hereof and all of which are
subject to change, possibly with retroactive effect. The Company has not
requested, and will not request, a ruling from the U.S. Internal Revenue Service
(the "IRS") with respect to any of the U.S. Federal income tax consequences
described below, and as a result, there can be no assurance that the IRS will
not disagree with or challenge any of the conclusions set forth herein.
 
LOSS OF S CORPORATION STATUS
 
     The status of the Company as an "S Corporation" under Subchapter S of the
Code terminated as a result of the issuance of the Units in the Initial
Offering. As a result, the Company became taxable under the Code on its taxable
income at the entity level as a regular "C" corporation, generally at the rate
of 35%. Additionally, its income, losses and other tax items no longer "flow
through" to its shareholders, who instead are taxed on the Company's
distributions, which are treated as ordinary dividend income to the extent they
do not exceed the Company's current and accumulated earnings and profits, with
any excess generally taxable as capital gain. The Company also became subject to
entity-level taxation in many states that is less favorable than the state tax
treatment afforded S corporations.
 
U.S. HOLDERS
 
     The following discussion is limited to persons who or which are U.S.
Holders that acquired Original Preferred Shares for cash upon their original
issuance. For these purposes, "U.S. Holder" means (i) an individual who is a
citizen or resident of the United States, (ii) a corporation or other entity
taxable as a corporation created or organized under the laws of the United
States or any political subdivision thereof or therein, (iii) an estate the
income of which is subject to U.S. federal income tax regardless of its source,
(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 United
States trustees have the authority to control all substantial decisions of the
trust or (v) any person or entity whose worldwide income or gain is otherwise
subject to U.S. federal income tax on a net income basis.
 
  Classification of Series A Preferred Stock
 
     Although the characterization of an instrument as debt or equity is a
factual determination the outcome of which cannot be predicted with certainty,
the Company intends to treat the Series A Preferred Stock as equity rather than
debt for U.S. federal income tax purposes. The remainder of this discussion
assumes that such treatment will be respected, but no opinion is either
expressed or implied on this issue.
 
                                       115
<PAGE>   121
 
  Series A Preferred Stock
 
     Dividends
 
     Distributions on the Series A Preferred Stock will constitute dividends to
the extent they are paid from current or accumulated earnings and profits of the
Company (as determined under U.S. federal income tax principles). Since the
Contingent Warrants are not separable from the Series A Preferred Stock until
the later of the Contingent Warrant Release Date and the Separation Date, the
Company intends to treat the Contingent Warrants as a distribution with respect
to the Series A Preferred Stock on each applicable Contingent Warrant Release
Date. Thus, the fair market value of the Contingent Warrants, if any,
distributed on each applicable Contingent Warrant Release Date will be a taxable
distribution to holders of the Series A Preferred Stock. Such amount will also
be the initial tax basis of the Contingent Warrants for U.S. federal income tax
purposes.
 
     In addition to the amount of cash and Contingent Warrants received, a U.S.
Holder may be treated as having received an annual distribution, taxable as a
dividend to the extent of current or accumulated earnings and profits of the
Company, in an amount equal to the annual accrual of the difference between the
issue price of such Series A Preferred Stock and the redemption price (as
discussed below) of such stock (the "Redemption Premium"). Such accrual will be
determined under a constant yield method that will result in increasing amounts
of accruals of income over the accrual period. The accrual will not be required,
however, if the difference between the issue price of the Series A Preferred
Stock and the redemption price of such stock does not exceed a de minimis
amount, as determined under principles similar to the principles of Section
1273(a)(3) of the Code.
 
     For purposes of determining the Redemption Premium, the Company intends to
treat the redemption price as the amount that will be paid upon retirement of
the Series A Preferred Stock on September 1, 2009. The IRS may assert, however,
that the Redemption Premium should be determined by using one of the higher
redemption prices that apply (1) in the event of an optional redemption by the
Company after September 1, 2003 (an "Optional Redemption") or (2) in the event
of a mandatory redemption by the Company following a Permitted Senior Notes
Offering or a Public Equity Offering (a "Mandatory Redemption"). The Company
believes that using a redemption price applicable to an Optional Redemption to
calculate the Redemption Premium is not required because, as of the issue date,
redemption pursuant to the Optional Redemption is not more likely than not to
occur, as described in Treasury Regulation Section 1.305-5(b)(3). The Company
believes that using a redemption price applicable to a Mandatory Redemption to
calculate the Redemption Premium is not required because, under Section
305(c)(1) of the Code and Treasury Regulation Section 1.305-5(b)(2) the Company
should not be treated as required to redeem the Series A Preferred Stock "at a
specified time," since (1) as of the issue date it is not possible to ascertain
the time at which a Mandatory Redemption might occur, if at all, and (2) it is
possible that, as of the issue date, the likelihood of a Mandatory Redemption
might be regarded as remote. However, despite the language of the Code and
Regulation section cited above, the preamble to these regulations contemplates
that a redemption triggered by an initial public offering may be treated as
non-remote, and the IRS may be successful in making such a contention. In this
event, the redemption price could be deemed to be as high as 108% of the
liquidation preference of the Series A Preferred Stock; the amount of the
Redemption Premium, and therefore the amounts of the income accruals described
above, would be correspondingly greater than the accruals, if any, determined by
the Company; and the income accruals would be required to be taken into account
entirely in a period or periods prior to the date on which the Mandatory
Redemption is deemed to occur for this purpose.
 
     The Company's determination of the amount(s) of any required accruals of
Redemption Premium is binding on all U.S. Holders of the Series A Preferred
Stock (who may obtain this information from the Company) other than a U.S.
Holder that explicitly discloses that its determination of the amounts, if any,
of such accruals differs from that of the Company. Such disclosure must be made
on a statement attached to the U.S. Holder's timely filed federal income tax
return for the taxable year that includes the date the U.S. Holder acquired the
Series A Preferred Stock. Each U.S.
                                       116
<PAGE>   122
 
Holder should consult its own tax advisor concerning the appropriate accruals of
Redemption Premium and related disclosure requirements.
 
     Any dividends on the Series A Preferred Stock that are not paid in cash
will accrue and compound, and will therefore be payable upon the optional or
mandatory redemption of the Series A Preferred Stock. The tax treatment of such
accruing and compounding dividends ("Accumulated Dividends") is not free from
doubt. Under current law, it appears that Accumulated Dividends would not be
treated as having been received by holders of the Series A Preferred Stock until
such Accumulated Dividends were actually paid in cash (and would then be taxable
distributions for U.S. federal income tax purposes treated as dividends.) The
legislative history to the 1990 amendments to Section 305(c) of the Code,
however, grants the IRS authority to issue regulations (possibly with
retroactive effect) that would treat such Accumulated Dividends as part of the
redemption price of the stock. If Accumulated Dividends were included in the
redemption price of the Series A Preferred Stock, a holder would be required to
take such Accumulated Dividends into account in determining the amount that
constitutes the redemption premium price, as described above. The effect of such
treatment would be to treat such holder as having received such Accumulated
Dividends as constructive distributions at the time they accrue, rather than at
the time they are paid in cash. Until regulations requiring such treatment with
respect to Accumulated Dividends are issued, however, the Company intends to
take the position that Accumulated Dividends on Series A Preferred Stock need
not be treated as received by a holder until such time as such Accumulated
Dividends are actually paid to such holder in cash, and will report to the IRS
on that basis.
 
     To the extent that the amount of (1) any actual distribution (including
those of Accumulated Dividends) or (2) any constructive distribution resulting
from the accrual of Redemption Premium on the Series A Preferred Stock
(including distributions of Contingent Warrants) exceeds the Company's current
and accumulated earnings and profits allocable to such distributions (as
determined for federal income tax purposes), such distribution will be treated
as a return of capital, thus reducing the U.S. Holder's adjusted tax basis in
such Series A Preferred Stock. Any such excess distribution that is greater than
the U.S. Holder's adjusted tax basis in the Series A Preferred Stock will be
taxed as capital gain and will be long-term capital gain if the U.S. Holder's
holding period for such Series A Preferred Stock exceeds one year.
 
     Dividends Received Deduction
 
     Under Section 243 of the Code, corporate U.S. Holders generally will be
able to deduct 70% of the amount of any distribution qualifying as a dividend.
There are, however, many exceptions and restrictions relating to the
availability of such dividends received deduction.
 
     Section 246A of the Code reduces the dividends received deduction allowed
to a corporate U.S. Holder that has incurred indebtedness "directly
attributable" to its investment in portfolio stock. Section 246(c) of the Code
requires that, in order to be eligible for the dividends received deduction, a
corporate U.S. Holder must, among other things, hold the shares of the Series A
Preferred Stock for tax purposes for a minimum of 46 days (91 days in the case
of certain preferred stock dividends attributable to a period or periods
aggregating in excess of 366 days) during the 90-day period beginning on the
date which is 45 days before the date on which such share becomes ex-dividend
with respect to such dividend (during the 180-day period beginning on the date
which is 90 days before such ex-dividend date in the case of certain preferred
stock dividends attributable to a period or periods aggregating in excess of 366
days). A U.S. Holder's holding period for these purposes is suspended during any
period in which it has certain options or contractual obligations with respect
to substantially identical stock or holds one or more other positions with
respect to substantially similar or related property that diminishes the risk of
loss from holding the Series A Preferred Stock. No deduction is allowed if the
corporate U.S. Holder is under an obligation to make related payments with
respect to positions in substantially similar or related property. To the extent
the dividends received deduction is allowed, a corporate U.S. Holder's
liability, if any, for alternative minimum tax may be increased.

     Under Section 1059 of the Code, a corporate U.S. Holder is required to
reduce its tax basis (but not below zero) in the Series A Preferred Stock by the
nontaxed portion of any "extraordinary dividend" if such stock has not been held
for tax purposes for more than two years before the earliest of the date such
dividend is declared, announced, or agreed to. Generally, the nontaxed portion
of an extraordinary dividend is the amount excluded from income by operation of
the dividends received deduction provisions of Section 243 of the Code. An
extraordinary dividend on the Series A Preferred Stock generally would be a
dividend that (i) equals or exceeds 5% of the corporate U.S. Holder's adjusted
tax basis in the Series A Preferred Stock, treating all dividends having
ex-dividend dates within an 85-day period as one dividend or (ii) exceeds 20% of
the corporate U.S. Holder's adjusted tax basis in the Series A Preferred Stock,
treating all dividends having ex-dividend dates within a 365-day period as one
dividend. In determining whether a dividend paid on the Series A Preferred Stock
is an extraordinary dividend, a corporate U.S. Holder may elect to substitute
the fair market value of the stock for such U.S. Holder's adjusted tax basis for
purposes of applying these tests, provided such fair market value is established
to the satisfaction of the Secretary of the Treasury as of the day before the
ex-dividend date. An extraordinary dividend also includes any amount treated as
a dividend in the case of a redemption that is non-pro rata as to all
stockholders or in partial liquidation of the Company or which would not have
been treated as a dividend if any options had not been taken into account under
Section 318(a)(4) of the Code or Section 304(a) of the Code had not applied,
regardless of the stockholder's holding period and regardless of the size of the
dividend. If any part of the nontaxed portion of an extraordinary dividend is
not applied to reduce the U.S. Holder's tax basis as a result of the limitation
on reducing such basis below zero, such part will be treated as capital gain and
will be recognized in the taxable year in which the extraordinary dividend is
received.
 
     Special rules exist with respect to extraordinary dividends for "qualified
preferred dividends." A qualified preferred dividend is any fixed dividend
payable with respect to any share of stock which (i) provides for fixed
preferred dividends payable not less frequently than annually and (ii) is not in
arrears as to dividends at the time the U.S. Holder acquired such stock. A
qualified preferred dividend does not include any dividend payable with respect
to any share of stock if the actual rate of return of such stock exceeds 15%.
Section 1059 does not apply to qualified preferred dividends if the corporate
U.S. Holder holds the stock with respect to which the dividends are paid for
more than five years. If the U.S. Holder disposes of such stock before it has
been held for more than five years, the amount subject to extraordinary dividend
treatment with respect to qualified preferred dividends is limited to the excess
of the actual rate of return over the stated rate of return. Actual or stated
rates of return are the actual or stated dividends expressed as a percentage of
the lesser of (1) the U.S. Holder's adjusted tax basis in such stock or (2) the
liquidation preference of such stock. CORPORATE U.S. HOLDERS ARE URGED TO
CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE POSSIBLE APPLICATION OF SECTION
1059 TO THEIR OWNERSHIP OR DISPOSITION OF THE SERIES A PREFERRED STOCK.
 
     Disposition of Preferred Stock
 
     A U.S. Holder's adjusted tax basis in the Series A Preferred Stock will, in
general, be the U. S. Holder's initial tax basis of such Series A Preferred
Stock increased by the Redemption Premium, if any, previously included in income
by the U.S. Holder. A corporate U.S. Holder's tax basis may be further adjusted
by the extraordinary dividend provisions discussed above. Upon the sale or other
disposition of Series A Preferred Stock (other than by redemption), a U.S.
Holder will generally recognize capital gain or loss equal to the difference
between the amount realized upon the disposition and the adjusted tax basis of
the Series A Preferred Stock. Such gain or loss will be capital gain or loss and
will be long-term capital gain or loss if at the time of sale, exchange, or
other disposition the Series A Preferred Stock has been held for more than one
year. The deductibility of capital losses is subject to limitations.
 
                                       118
<PAGE>   124
 
     A redemption of the Series A Preferred Stock by the Company would be
treated, under Section 302 of the Code, either as a sale or exchange giving rise
to capital gain or loss or as a dividend. If a redemption is treated as a sale
or exchange, a U.S. Holder will generally recognize capital gain or loss as
described above, except to the extent that the redemption price includes
dividends which have been declared but not paid prior to the redemption, which
will be treated as dividends as described above. If a redemption of shares of
the Series A Preferred Stock is treated as a dividend with respect to a
particular U.S. Holder under Section 302 of the Code, such U.S. Holder (i) will
not recognize any loss on the redemption, (ii) will recognize dividend income
(rather than capital gain) in an amount equal to its proportionate share of the
Company's current or accumulated earnings and profits. Pursuant to Section 302
of the Code, the redemption will not be treated as a dividend, if after giving
effect to the constructive ownership rules of Section 318 of the Code, the
redemption (i) represents a "complete termination" of the redeeming U.S.
Holder's stock interest in the Company, (ii) is "substantially disproportionate"
with respect to the redeeming U.S. Holder or (iii) is "not essentially
equivalent to a dividend" with respect to the redeeming U.S. Holder, all within
the meaning of Section 302(b) of the Code. Under the constructive ownership
rules of Section 318 of the Code, a U.S. Holder of a Warrant will be treated as
owning the Common Stock which would be received pursuant to the exercise of such
Warrant. Accordingly, a redemption of Series A Preferred Stock could not,
standing alone, satisfy the "complete termination" test if the U.S. Holder owns
Warrants before and after the redemption, but could satisfy such test if the
U.S. Holder does not own Warrants or any other stock interest (including through
constructive ownership) after the redemption. A redemption will be "not
essentially equivalent to a dividend" as to a particular U.S. Holder if it
results in a "meaningful reduction" in such U.S. Holder's interest in the
Company (after application of the constructive ownership rules of Section 318 of
the Code). In general, there are no fixed rules for determining whether a
"meaningful reduction" has occurred. EACH U.S. HOLDER SHOULD CONSULT ITS OWN TAX
ADVISOR AS TO ITS ABILITY IN LIGHT OF ITS OWN PARTICULAR CIRCUMSTANCES TO
SATISFY ANY OF THE FOREGOING TESTS. ADDITIONALLY, CORPORATE U.S. HOLDERS SHOULD
CONSULT THEIR OWN TAX ADVISORS CONCERNING THE AVAILABILITY OF THE CORPORATE
DIVIDENDS RECEIVED DEDUCTION AND THE POSSIBLE APPLICATION OF THE EXTRAORDINARY
DIVIDEND RULES OF SECTION 1059 OF THE CODE TO A DISTRIBUTION THAT IS TAXABLE AS
A DIVIDEND.
 
     Exchange Offer
 
     The exchange of Original Preferred Shares for substantially identical
preferred stock (i.e., the New Preferred Shares) pursuant to this Exchange Offer
should not constitute a taxable event for U.S. federal income tax purposes. As a
result, (i) a U.S. Holder of Original Preferred Shares should not recognize
taxable gain or loss as a result of the exchange of Original Preferred Shares
for New Preferred Shares pursuant to the Exchange Offer, (ii) the holding period
of the New Preferred Shares should include the holding period of the Original
Preferred Shares surrendered in exchange therefor and (iii) a U.S. Holder's
adjusted tax basis in the New Preferred Shares should be the same as such U.S.
Holder's adjusted tax basis in the Original Preferred Shares surrendered in
exchange therefor.
 
     Information Reporting and Backup Withholding
 
     A noncorporate U.S. Holder of Series A Preferred Stock may be subject to
backup withholding at a 31% rate with respect to "reportable payments", which
include dividends (including any accrual of Redemption Premium) paid on Series A
Preferred Stock or the proceeds of a sale or exchange of the Series A Preferred
Stock. The payor of any reportable payments will be required to deduct and
withhold 31% of such payments if (i) the payee fails to furnish a correct
Taxpayer Identification Number (a "TIN") to the payor in the prescribed manner,
(ii) the IRS notifies the payor that the TIN furnished by the payee is
incorrect, (iii) the payee has failed properly to report the receipt of certain
reportable payments and the IRS has notified the payor that backup withholding
is required or (iv) the payee fails to certify under penalties of perjury that
such payee is not subject to backup withholding. If any one of these events
occurs with respect to a U.S. Holder of Series A Preferred


                                       119
<PAGE>   125
 
Stock, the payer of any reportable payment will be required to withhold 31% of
any such reportable payments with respect thereto.
 
     Any amount withheld from a payment to a U.S. Holder under the backup
withholding rules will be allowed as a refund or credit against such holder's
U.S. federal income tax liability, so long as the required information is
provided to the IRS. The payer of any reportable payment generally will report
to a U.S. Holder of Series A Preferred Stock and to the IRS the amounts of any
reportable payments made in respect to the Series A Preferred Stock for each
calendar year and the amount of tax withheld, if any, with respect to such
payments.
 
NON-U.S. HOLDERS
 
     The discussion above is applicable only to U.S. Holders. The Series A
Preferred Stock may not be an appropriate investment for persons other than U.S.
Holders ("Non-U.S. Holders"), since dividends on the Series A Preferred Stock
(whether paid in cash or in-kind) generally will be subject to the withholding
of U.S. federal income tax at a 30% rate (or lower applicable treaty rate,
subject to applicable requirements, including the requirement to provide
specified documentation of foreign status). Tax consequences for Non-U.S.
Holders, if any, may differ if their investment in Series A Preferred Stock is
treated as effectively connected with their conduct of a trade or business
within the United States. The tax consequences to Non-U.S. Holders may be
complex and in some cases, adverse, and are not described herein except to the
limited extent set forth in this paragraph. Persons who are Non-U.S. Holders
should consult their own tax advisors prior to acquiring Series A Preferred
Stock.
 
     PROSPECTIVE PURCHASERS OF UNITS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
WITH RESPECT TO THE APPLICATION TO THEIR PARTICULAR SITUATIONS OF U.S. FEDERAL
INCOME TAX LAWS, AS WELL AS THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING
JURISDICTION.
 
                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives New Preferred Shares for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Preferred Shares. The
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Preferred Shares received
in exchange for Original Preferred Shares where such shares were acquired as a
result of market-making activities or other trading activities. The Company has
agreed that it will make this Prospectus, as amended or supplemented, available
to any broker-dealer for use in connection with any such resale for a period
ending 90 days after the completion of the Exchange Offer.
 
     The Company will not receive any proceeds from any sale of New Preferred
Shares by broker-dealers. New Preferred Shares received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the New Preferred Shares or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such New
Preferred Shares. Any broker-dealer that resells New Preferred Shares that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such New Preferred Shares may
be deemed to be an "underwriter" within the meaning of the Securities Act and
any profit of any such resale of New Preferred Shares and any commissions or
concessions received by any such persons may be deemed to be underwriting
 
                                       120
<PAGE>   126
 
compensation under the Securities Act. The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
 
     The Company has agreed to pay all expenses incident to the Exchange Offer
other than the expenses of counsel for the holders of the Original Preferred
Shares and commissions or concessions of any brokers or dealers, and will
indemnify the holders of the Original Preferred Shares (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
 
                           VALIDITY OF THE SECURITIES
 
     The validity of the New Preferred Shares will be passed upon for the
Company by Hale and Dorr LLP, Boston, Massachusetts.
 
                            INDEPENDENT ACCOUNTANTS
 
     The financial statements of the Company as of December 31, 1997 and 1996
and for each of the years in the three-year period ended December 31, 1997
included in this Prospectus have been audited by PricewaterhouseCoopers LLP,
independent accountants, as stated in their report appearing herein.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and
Stockholders of Network Plus Corp.:
 
     In our opinion, the accompanying balance sheets and the related statements
of operations and retained earnings and of cash flows present fairly, in all
material respects, the financial position of Network Plus, Inc., a wholly owned
subsidiary of Network Plus Corp., at December 31, 1997 and 1996, and the results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1997, in conformity with generally accepted accounting
principles. 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 of these statements in
accordance with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS ACTIVITY
 
     Network Plus, Inc. (the "Company"), a wholly owned subsidiary of Network
Plus Corp. (see Note 12), is a switch-based carrier and switchless reseller of
long distance telecommunications services, principally to small and medium-sized
businesses in the Northeastern and Southeastern regions of the United States.
Revenues are derived from the sale of domestic and international telephone
services, calling cards, debit cards and paging services. The Company operates
two telephony switches, located in Quincy, Massachusetts and Orlando, Florida,
and contracts with Sprint Communications Company, LP ("Sprint") to provide
switching and dedicated voice and data services for a portion of the Company's
telecommunications traffic.
 
CASH EQUIVALENTS
 
     All highly liquid cash investments with maturities of three months or less
at date of purchase are considered to be cash equivalents.
 
REVENUE RECOGNITION AND ACCOUNTS RECEIVABLE
 
     Telecommunication revenues and accounts receivable are recognized when
calls are completed or when services are provided. Accounts receivable include
both billed and unbilled amounts, and are reduced by an estimate for
uncollectible amounts.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are recorded at cost and are depreciated using the
straight-line method over the estimated useful lives of the assets. Leasehold
improvements are amortized over the shorter of the lease term or the estimated
useful life of the improvements. Upon retirement or other disposition of
property and equipment, the cost and related depreciation are removed from the
accounts and the resulting gain or loss is reflected in earnings.
 
CAPITAL LEASES
 
     Capital leases, those leases which transfer substantially all benefits and
risks of ownership, are accounted for as acquisitions of assets and incurrences
of obligations. Capital lease amortization is included in depreciation and
amortization expense, with the amortization period restricted to the lease term.
Interest on the related obligation is recognized over the lease term at a
constant periodic rate.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
INCOME TAXES
 
     Effective March 1, 1992, the Company elected by the consent of its
stockholders to be taxed under the provisions of Subchapter S of the Internal
Revenue Code. Under those provisions, the Company does not pay corporate federal
income taxes on its taxable income. Instead, the stockholders are liable for
individual income taxes on their share of the Company's taxable income.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
The Company continues to pay state income taxes in those states that do not
fully recognize the Subchapter S provision and states that assess certain
franchise taxes.
 
CONCENTRATION OF RISK
 
     Financial instruments that potentially subject the Company to
concentrations of credit risk consist primarily of trade accounts receivable. In
addition, risk exists in cash deposited in banks that may, at times, be in
excess of FDIC insurance limits. Cash balances are managed daily to reduce
revolving credit borrowings. The trade accounts receivable risk is limited due
to the breadth of entities comprising the Company's customer base and their
dispersion across different industries and geographical regions. The Company
evaluates the creditworthiness of customers, as appropriate, and maintains an
adequate allowance for potential uncollectible accounts.
 
EARNINGS (LOSS) PER SHARE
 
     The Company computes and reports earnings per share in accordance with the
provisions of SFAS No. 128, "Earnings Per Share". The computations of basic and
diluted earnings (loss) per common share are based upon the weighted average
number of common shares outstanding and potentially dilutive securities.
Potentially dilutive securities include convertible preferred stock, stock
options and warrants. There were no potentially dilutive securities outstanding
during 1997, 1996 or 1995.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
130"), which is effective for fiscal years beginning after December 15, 1997,
including interim periods. SFAS 130 requires the presentation of comprehensive
income and its components. Comprehensive income presents a measure of all
changes in equity that result from recognized transactions and other economic
events during the period other than transactions with stockholders. The Company
will adopt SFAS 130 in the first quarter of 1998 and does not expect
comprehensive income to differ from reported net income.
 
     In July 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures About Segments of an
Enterprise and Related Information" ("SFAS 131"), which is effective for fiscal
years beginning after December 15, 1997. Interim reporting disclosures are not
required in the first year of adoption. SFAS 131 specifies revised guidelines
for determining an entity's operating segments and the type and level of
operating information to be disclosed. SFAS 131 changes current practice under
SFAS 14 by establishing a new framework on which to base segment reporting. The
management approach described in SFAS 131 expands the required disclosures for
each segment. The Company will adopt SFAS 131 in its year ending December 31,
1998, and has yet to determine the impact of such adoption on the reporting of
its results of operations as currently presented.
 
     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use". The Company does not believe
that this pronouncement will have a material impact on its business or results
of operations.

RECLASSIFICATIONS
 
     Certain amounts in the financial statements for prior years have been
reclassified to conform with the current year presentation. Such
reclassifications had no effect on previously reported results of operations.
 
2.  RELATED PARTY TRANSACTIONS
 
     In December 1997, the Company's stockholders made loans to the Company
totaling $1,755. Interest on the loans accrues at the prevailing prime rate
(8.5% at December 31, 1997) and is payable monthly. There is no required period
for principal repayment. The loans were repaid in May 1998 and, accordingly,
have been classified as a current liability in the accompanying balance sheet.
 
     The Company had a service arrangement through May 1997 with a marketing
company, the controlling stockholders of which include the Company's
stockholders. The marketing company provided services relative to establishing,
training and expanding the Company's sales organization. For the years ending
December 31, 1997, 1996 and 1995, the amounts paid to the marketing company were
$55, $132 and $197, respectively.
 
     Office space, located in Quincy, Massachusetts, is leased from a trust, the
beneficiaries of which are the stockholders of the Company (see Note 11). The
Company makes monthly rental payments of $36. In each of the years ending
December 31, 1997, 1996, and 1995, the amount paid to the trust was $431.

     In 1995, the Company sold three separate billing bases of customer accounts
to other telecommunications companies for cash totaling approximately $8,422 and
warrants to purchase shares of common stock of Tel-Save Holdings, Inc.
("Tel-Save"). The cash received was recognized as miscellaneous income in 1995.
The Company was required to fulfill certain sales volume obligations in order to
exercise the warrants. As of December 31, 1995, the Company had not met those
obligations and, accordingly, had ascribed no value to the warrants.
 
     During 1996, the Company met the sales volume obligations to exercise a
portion of the outstanding warrants. Certain of these warrants were exercised
and common stock related to those
 
                                       F-8

warrants was sold by the Company, resulting in net proceeds and income of
$1,367. The remainder of the warrants that became exercisable in 1996 were
subsequently exercised in 1997. These warrants were classified as investments
and were valued at approximately $2,093 at December 31, 1996 using an
established valuation model. A total of approximately $3,460 was recognized as
other income in 1996 relating to these warrants.
 
     The agreements between Tel-Save and the Company required the transfer of
ownership of the common stock certificates from Tel-Save to the Company upon the
Company meeting certain requirements, which the Company, based upon available
information, believed it had met in 1996 and 1997. Accordingly, in 1997, cash
payments totaling $3,570 were made to exercise all outstanding warrants. In
total, payments for warrants in 1997 were believed to entitle the Company to
765,000 shares of Tel-Save common stock, subject to the registration of the
shares by Tel-Save. The shares were registered with the Securities and Exchange
Commission in November 1997, but common stock certificates were not physically
transferred to the Company.
 
     In order to take physical possession of the Tel-Save common stock
certificates, the Company filed suit against Tel-Save in January 1998. On June
24, 1998, a settlement agreement was signed between the parties pursuant to
which Tel-Save returned $1,470 paid by the Company during 1997 in its attempt to
exercise the final warrant for 315,000 shares, and canceled that warrant. In
addition, Tel-Save issued the remaining 450,000 shares to the Company and
simultaneously repurchased such shares for $8,030. There are no continuing
obligations between the parties. Accordingly, the Company's investment in
Tel-Save at December 31, 1997 was valued at the $9,500 received pursuant to the
settlement in June 1998, and other income of $3.8 million was recorded in 1997
to reflect this valuation.

     In 1997, upon review of the Company's experience and expectations for
upgrades and replacement of equipment, the Company changed the estimated useful
life of its switching equipment from 12 years to 5 years. Depreciation expense
in 1997 was approximately $136 more than what would have otherwise been reported
had the change in estimate not been made. Annual depreciation expense related to
these assets will be approximately $407 more through 2002 than what would have
otherwise been reported had the change not been made.
 
     In August 1997, the Company entered into a sale and leaseback of its
switching equipment. The equipment was sold at book value, which approximates
market value, and, consequently, no gain or loss was recorded on the sale. The
Company has the right to reacquire the equipment at the end of the lease's
five-year term.

7.  REVOLVING CREDIT AGREEMENT
 
     The Company has a revolving line of credit with Fleet National Bank
("Fleet") for borrowings up to $7,000, including letters of credit, which
expires on May 31, 1998. Availability in excess of $5,000 is based upon a
percentage of accounts receivable. Interest is payable monthly at the bank's
prime rate or available LIBOR options. The revolving line of credit requires the
Company to meet certain debt service, liquidity and tangible net worth
covenants. At December 31, 1997, cash borrowings under the line of credit
totalled $4,510 and letters of credit issued in the ordinary course of business
totalled $120. At December 31, 1996, cash borrowings under the line totalled
$2,000 and there were no outstanding letters of credit. The interest rate on
such borrowings was 8.5% at December 31, 1997 and 8.25% at December 31, 1996.
The maximum borrowings under the agreement in 1997 and 1996 were $5,000 and
$3,000, respectively.
 
     On May 1, 1998, the Company entered into new revolving credit agreement
with Fleet, which allows for up to $23 million of borrowings, based upon a
percentage of accounts receivable. The new agreement has a term of three years.
Interest is payable monthly at Fleet's prime rate or available LIBOR options.
The revolving credit agreement requires the Company to meet certain gross
margin, operating income and tangible net worth covenants. All outstanding notes
payable were paid in full with proceeds from the new facility.

agreement in the amount of $1,000 at a fixed rate of 8.11% per year,
collateralized by switching equipment. This loan was repaid in October 1997. At
December 31, 1996, the unpaid principal on the loan was $846.
 
     The Company's capital leases contain various covenants which, among other
things, require the Company to maintain specified ratios of total liabilities to
net worth and to meet certain net income requirements.
 
9.  LEASE COMMITMENTS
 
     The Company has entered into noncancellable operating leases for office
space in several locations in the eastern United States. The leases have
termination dates through 2003 and require the payment of various operating
costs including condominium fees. Rental expense related to the leases for the
years ended December 31, 1997, 1996 and 1995 were $733, $688 and $501,
respectively.
 
     Minimum lease payments for the next five years and thereafter are as
follows:

10.  UNEARNED CREDITS
 
     In 1993 and 1994, the Company, through special sales promotions offered
through AT&T on three-year service contracts, received cash based on maintaining
annual sales commitment levels over a specific dollar amount. The total amounts
received from the AT&T promotions were amortized over the three-year length of
each contract and were fully amortized prior to 1997. Amortization of these
credits included in revenue in 1996 and 1995 was $1,810 and $2,436,
respectively.
 
11.  COMMITMENTS AND CONTINGENCIES
 
     The Company is contingently liable as a guarantor on a bank loan made to
the trust from whom the Company leases office space in Quincy, Massachusetts
(see Note 2). The outstanding balance of the loan at December 31, 1997 and 1996
is $1,486 and $1,546, respectively.
 
12.  STOCKHOLDERS' EQUITY
 
     On July 15, 1998, the stockholders of the Company created Network Plus
Corp. ("NP Corp."), which was incorporated in the State of Delaware. NP Corp.
expects to elect to be taxed under the provisions of Subchapter S of the
Internal Revenue Code. NP Corp. became the owner of 100% of the issued and
outstanding common stock of the Company on July 15, 1998, the date on which the
stockholders of the Company contributed their ownership interest in the Company
totaling 100 shares of common stock in return for 10,000,000 shares of common
stock, representing 100% of the ownership interest of NP Corp. These
transactions were initiated by the stockholders of the Company to achieve a
number of business objectives including an increase in the number of shares of
common stock authorized for issuance and issued and outstanding. The Company has
accounted for the effects of these transactions as a 100,000-for-1 stock split
and retroactively restated the accompanying financial statements to reflect
these transactions.
 
COMMON STOCK
 
     The certificate of incorporation of NP Corp. authorizes the issuance of up
to 20,000,000 shares of $.01 par value common stock. There are 10,000,000 shares
of common stock issued and outstanding and held of record by two stockholders as
of July 15, 1998. The holders of common stock are entitled to receive dividends
when and as dividends are declared by the Board of Directors of NP Corp. out of
funds legally available therefor, provided that if any shares of preferred stock
are at the time outstanding, the payment of dividends on the common stock or
other distributions may be subject to the declaration and payment of dividends
on outstanding shares of preferred stock. Holders of common stock are entitled
to one vote per share on all matters submitted to a vote of the stockholders,
including the election of directors. Upon any liquidation, dissolution or
winding up of the affairs of NP Corp., whether voluntary or involuntary, any
assets remaining after the satisfaction in full of the prior rights of creditors
and the aggregate liquidation preference of any preferred stock then outstanding
will be distributed to the holders of common stock ratably in proportion to the
number of shares held by them. The common stock is not publicly traded.
 
PREFERRED STOCK
 
     Under the certificate of incorporation of NP Corp., the Board of Directors
has the authority to issue up to 1,000,000 shares of $.01 par value preferred
stock from time to time in one or more series with such preferences, terms and
rights as the Board of Directors may determine without further action by the
stockholders of NP Corp. Accordingly, the Board of Directors has the power to
establish the provisions, if any, relating to dividends, voting rights,
redemption rates, sinking funds,

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
liquidation preferences and conversion rights for any series of preferred stock
issued in the future. There are currently no shares of preferred stock
outstanding.
 
STOCK-BASED COMPENSATION PLANS
 
     On July 15, 1998, NP Corp. adopted the 1998 Stock Incentive Plan (the "1998
Incentive Plan"). The 1998 Incentive Plan provides for the grant of stock-based
awards to employees, officers and directors of, and consultants or advisors to,
NP Corp. Under the 1998 Incentive Plan, the Company may grant options that are
intended to qualify as incentive stock options ("incentive stock options")
within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code"), options not intended to qualify as incentive stock options
("non-statutory options"), restricted stock and other stock-based awards.
Incentive stock options may be granted only to employees of NP Corp. or its
subsidiaries. A total of 1,400,000 shares of common stock may be issued upon the
exercise of options or other awards granted under the 1998 Incentive Plan. The
number of shares with respect to which awards may be granted to any employee
under the 1998 Incentive Plan may not exceed 700,000 during any calendar year.
The exercisability of options or other awards granted under the 1998 Incentive
Plan may, in certain circumstances, be accelerated in connection with an
Acquisition Event (as defined in the 1998 Incentive Plan). Options and other
awards may be granted under the 1998 Incentive Plan at exercise prices that are
equal to, less than or greater than the fair market value of NP Corp.'s common
stock, and the Board generally retains the authority to reprice outstanding
options. The 1998 Incentive Plan expires in July 2008, unless sooner terminated
by the Board.
 
     On July 15, 1998, NP Corp. authorized the grant of a total of 741,140
options to purchase NP Corp. common stock at exercise prices at or above the
fair market value of NP Corp.'s common stock, as determined by its Board of
Directors. The options, when issued, will generally vest ratably over a period
of four years. NP Corp. and the Company intend to adopt the accounting
provisions of Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees", and the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock Based
Compensation". Accordingly, the Company's or NP Corp.'s results of operations
are not expected to be materially affected by the options granted to date under
this plan.
 
     On July 15, 1998, NP Corp. adopted the 1998 Director Stock Option Plan (the
"Director Plan"). Under the terms of the Director Plan, 5,000 shares of common
stock will be granted to each non-employee director upon his or her initial
election to the Board of Directors. Annual options to purchase 2,500 shares of
common stock will also be granted to each non-employee director on the date of
each annual meeting of stockholders, or on August 1 of each year if no annual
meeting is held by such date. Options granted under the Director Plan will vest
in four equal annual installments beginning on the first anniversary of the date
of grant. The exercisability of these options will be accelerated upon the
occurrence of an Acquisition Event (as defined in the Director Plan). The
exercise price of options granted under the Director Plan is equal to the fair
market value of the common stock on the date of grant. A total of 100,000 shares
of common stock may be issued upon the exercise of stock options granted under
the Director Plan. No options have been granted under this plan.
 
DIVIDEND
 
     On July 15, 1998, the Board of Directors of NP Corp. declared a dividend in
the aggregate amount of $5,000. As a result, it is anticipated that $2,500 will
be distributed to each of the stockholders of NP Corp. Following receipt of the
dividend, one stockholder will loan the Company $1,875 (representing the
distribution to that stockholder, net of the estimated tax liability resulting

from such distribution). Interest will accrue at Fleet's prime rate, and
interest and principal will be payable 10 days after redemption of the Series A
Preferred Stock.
 
13.  MAJOR SUPPLIER
 
     The Company has an agreement with Sprint to provide switching and dedicated
voice and data services. At expiration or any time prior, the Company can seek
to renew all material aspects of the agreement with Sprint. In the event that
renewal does not occur, the Company may be able to negotiate equally beneficial
terms with other major telecommunications companies. Should neither of these
alternatives be possible, there could be material adverse implications for the
Company's financial position and operations. Management's experience has been to
renegotiate agreements annually to ensure receiving competitive pricing, and
management believes the Company will be able to continue to renegotiate the
agreements. The current agreement was renegotiated, effective February 1998, and
will expire in February 2000.
 
14.  EMPLOYEE BENEFIT PLAN
 
     The Company sponsors a 401(k) and profit sharing plan (the "Plan") which is
open to all eligible employees under the Plan's provisions. The terms of the
Plan allow the Company to determine its annual profit sharing contribution.
There were no Company contributions to the Plan in 1997 or 1996. The Company's
contribution to the Plan in 1995 was $175.
 
15.  SUBSEQUENT EVENT
 
     On September 3, 1998, NP Corp. (see Note 12) issued 40,000 shares of 13.5%
Series A Cumulative Preferred Stock Due 2009 and initial warrants to purchase,
for $.01 per share, 310,000 shares of NP Corp.'s common stock (and contingent
warrants to purchase 600,000 shares of common stock) resulting in proceeds to NP
Corp. of $37.5 million, net of issuance costs of $2.5 million. A total value of
$4.35 million was ascribed to the initial warrants, net of issuance costs of
$0.3 million, and was accounted for as additional paid-in capital. The value
ascribed to the initial warrants was recorded as a discount to the preferred
stock which will be accreted to the preferred stock balance over an assumed
maturity period. Through September 3, 1998, NP Corp.'s activities consist
principally of the issuance of its preferred stock and warrants.
 
     The issuance of the preferred stock terminated NP Corp.'s election to be
taxed under the provisions of Subchapter S of the Internal Revenue Code.
Accordingly, NP Corp. will provide for and report Federal and state income
taxes, if any.

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1.  BASIS OF PRESENTATION
 
     The accompanying Unaudited Interim Financial Statements of Network Plus,
Inc. (the "Company"), a wholly owned subsidiary of Network Plus Corp., have been
prepared in conformity with generally accepted accounting principles and, in the
opinion of management, include all adjustments, consisting of normal recurring
accruals, necessary for a fair presentation of the results for the interim
periods. The results of operations for the interim periods are not necessarily
indicative of the results to be expected for the year.
 
     These unaudited interim financial statements should be read in conjunction
with the financial statements and related notes in the Company's annual audited
Financial Statements. The balance sheet as of December 31, 1997 has been derived
from the audited financial statements as of that date.
 
     Certain amounts in the financial statements for the prior year have been
reclassified to conform with the current year presentation. Such
reclassifications had no effect on previously reported results of operations.
 
2.  RELATED PARTY TRANSACTIONS
 
     In December 1997, the Company's stockholders issued the Company loans
totaling $1,755. The loans were repaid on May 1, 1998.
 
     The Company had a service arrangement through May 1997 with a marketing
company, the shareholders of which have a controlling interest in the Company.
The marketing company provided services relative to establishing, training and
expanding the Company's sales organization. During the six months ended June 30,
1997, $55 was paid to the marketing company.
 
     Office space, located in Quincy, MA, is leased from a trust, the
beneficiaries of which are stockholders of the Company. The Company makes
monthly rental payments of $36. In each of the six-month periods ended June 30,
1998 and 1997, $216 was paid to the trust.

5.  REVOLVING CREDIT AGREEMENTS
 
     The Company had a revolving line of credit with Fleet National Bank
("Fleet") for borrowings up to $7,000 including letters of credit, which was
terminated on May 1, 1998 upon entering into a new revolving credit agreement,
described below. At June 30, 1998, cash borrowings under the new revolving
credit agreement totaled $9,000 and letters of credit issued in the ordinary
course of business totaled $1,020. At December 31, 1997, cash borrowings under
the new revolving credit agreement totaled $4,510 and letters of credit totaled
$120. The interest rate on such borrowings was 7.4% at June 30, 1998 and 8.5% at
December 31, 1997.
 
     On May 1, 1998, the Company entered into a new revolving credit agreement
with Fleet, which allows for up to $23,000 of borrowings, based upon a
percentage of accounts receivable. The new agreement has a term of three years.
Interest is payable monthly at Fleet's prime rate or available LIBOR options.
The revolving credit agreement requires the Company to meet certain gross
margin, operating income and tangible net worth covenants.
 
     On August 14, 1998, the Company entered into a commitment letter with
Goldman Sachs Credit Partners, L.P. for a $60,000 revolving credit facility (the
"GSCP Facility"), concurrent with the closing of which the Company expects to
terminate the Fleet agreement. The GSCP Facility will have a term of 18 months.
Under the GSCP Facility, $30,000 will be available upon closing and up to an
additional $30,000 will be available based upon a percentage of accounts
receivable. Interest is payable monthly at one percent above the prime rate. The
GSCP Facility will require the Company to meet, among other things, minimum
levels of revenues, access lines in service and earnings before interest, taxes,
depreciation and amortization.

                                                              =======       =======
</TABLE>
 
     The Company issued a promissory note, dated December 1, 1997, to Sprint for
repayment of $4,600 previously classified as accounts payable. On May 1, 1998,
the remaining balance of $3,700 due on the note was repaid.
 
     The Company received a waiver from the lender for a violation at June 30,
1998 of the debt-to-equity financial covenant of its capital lease. The Company
continues to classify a portion of the capital lease liability as non-current
based on the expectation that the Company will be in compliance in subsequent
periods.
 
7.  MAJOR SUPPLIER
 
     The Company has an agreement with Sprint to provide switching and dedicated
voice and data services. At expiration or any time prior, the Company can renew
all material aspects of the agreement with Sprint. In the event that renewal
does not occur, the Company may be able to negotiate equally beneficial terms
with other major telecommunications companies. Should neither of these
alternatives be possible, there could be material adverse implications for the
Company's financial position and operations. Management's experience has been to
renegotiate agreements annually to ensure receiving competitive pricing, and
management believes the Company will be able to continue to renegotiate the
agreement. The current agreement was renegotiated, effective February 1998, and
will expire February 2000.
 
8.  SIGNIFICANT CUSTOMER
 
     During the six months ended June 30, 1998, the Company had one customer
that accounted for 11% of the Company's revenue. No other customer comprised
greater than 10% of total revenue.
 
9.  EARNINGS PER SHARE
 
     The computations of basic and diluted earnings per common share are based
upon the weighted average number of common shares outstanding and potentially
dilutive securities. Potentially dilutive securities include convertible
preferred stock, stock options and warrants. No potentially dilutive securities
were outstanding during the six months ended June 30, 1998 or 1997.
 
10.  COMPREHENSIVE INCOME
 
     Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income". This Statement
establishes new rules for the reporting and display of comprehensive income and
its components; however, the adoption of this statement had no impact on the
Company's net income or stockholders' equity. There were no

adjustments required to calculate comprehensive income for either the six months
ended June 30, 1998 or 1997.
 
11.  NEW ACCOUNTING PRONOUNCEMENTS
 
     In 1997, Statement of Financial Accounting Standards No. 131 ("SFAS 131"),
"Disclosures about Segments of an Enterprise and Related Information", was
issued which establishes standards for segment reporting in a full set of
general purpose financial statements. Management has not yet evaluated the
effects of this change on the reporting of its results of operations. The
Company will adopt SFAS 131 for its fiscal year ending December 31, 1998.
 
     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1, "Accounting for the costs of Computer
Software Developed or Obtained for Internal Use". The Company does not believe
that this pronouncement will have a material impact on its business or results
of operations.
 
12.  SUBSEQUENT EVENT
 
     On September 3, 1998, Network Plus Corp. issued 40,000 shares of 13.5%
Series A Cumulative Preferred Stock Due 2009 and initial warrants to purchase,
for $0.1 per share, 310,000 shares of Network Plus Corp.'s common stock (and
contingent warrants to purchase 600,000 shares of common stock) resulting in
proceeds to Network Plus Corp. of $37.5 million, net of issuance costs of $2.5
million. A total value of $4.35 million was ascribed to the initial warrants,
net of issuance costs of $0.3 million, and was accounted for as additional
paid-in capital. The value ascribed to the initial warrants was recorded as a
discount to the preferred stock which will be accreted to the preferred stock
balance over an assumed maturity period. Through September 3, 1998, Network Plus
Corp.'s activities consist principally of the issuance of its preferred stock
and warrants.
 
     The issuance of the preferred stock terminated Network Plus Corp.'s
election to be taxed under the provisions of Subchapter S of the Internal
Revenue Code. Accordingly, Network Plus Corp. will provide for and report
Federal and state income taxes, if any.

                                    PART II
 
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law (the "DGCL") empowers a
Delaware corporation to indemnify any 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
(other than an action by or in the right of such corporation) by reason of the
fact that such person is or was a director, officer, employee or agent of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. A
corporation may, in advance of the final action of any civil, criminal,
administrative or investigative action, suit or proceeding, pay the expenses
(including attorneys' fees) incurred by any officer, director, employee or agent
in defending such action, provided that the director or officer undertakes to
repay such amount if it shall ultimately be determined that he or she is not
entitled to be indemnified by the corporation. A corporation may indemnify such
person against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding if he or she acted in good faith
and in a manner he or she reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
 
     A Delaware corporation may indemnify officers and directors in an action by
or in the right of the corporation to procure a judgment in its favor under the
same conditions, except that no indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, the corporation must indemnify him or
her against the expenses (including attorneys' fees) which he or she actually
and reasonably incurred in connection therewith. The indemnification provided is
not deemed to be exclusive of any other rights to which an officer or director
may be entitled under any corporation's by-law, agreement, vote or otherwise.
 
     In accordance with Section 145 of the DGCL, Article Eighth of the Company's
Certificate of Incorporation (the "Certificate") and the Company's By-laws (the
"By-laws") provide that the Company shall indemnify each person who is or was a
director, officer or employee of the Company (including the heirs, executors,
administrators or estate of such person) or is or was serving at the request of
the Company as director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise, to the fullest extent
permitted under subsections 145(a), (b), and (c) of the DGCL or any successor
statute. The indemnification provided by the Certificate and the By-laws shall
not be deemed exclusive of any other rights to which any of those seeking
indemnification or advancement of expenses may be entitled under any by-law,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his or her official capacity and as to action in another capacity
while holding such office, and shall continue as to a person who has ceased to
be a director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person. Expenses (including
attorneys' fees) incurred in defending a civil, criminal, administrative or
investigative action, suit or proceeding upon receipt of an undertaking by or on
behalf of the indemnified person to repay such amount if it shall ultimately be
determined that he or she is not entitled to be indemnified by the Company. The
Certificate further provides that a director of the Company shall not be
personally liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to the Company or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit. If the
DGCL is amended to authorize corporate action further eliminating
 
                                      II-1
<PAGE>   155
 
or limiting the personal liability of directors, then the liability of a
director of the Company shall be eliminated or limited to the fullest extent
permitted by the DGCL as so amended.
 
     The By-laws provide that the Company may purchase and maintain insurance on
behalf of its directors, officers, employees and agents against any liabilities
asserted against such persons arising out of such capacities.

ITEM 22.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement 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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of registrants
pursuant to the provisions described under Item 20 above, 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
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by 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 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 undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, 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.
 
     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in this Registration Statement when it became effective.

undersigned, thereunto duly authorized, in the City of Quincy, State of

                          CERTIFICATE OF INCORPORATION

                                       OF

                               NETWORK PLUS CORP.



         FIRST.  The name of the Corporation is:  Network Plus Corp.

         SECOND. The address of its registered office in the State of Delaware
is Corporation Trust Center, 1209 Orange Street, in the City of Wilmington,
County of New Castle. The name of its registered agent at such address is The
Corporation Trust Company.

         THIRD. The nature of the business or purposes to be conducted or
promoted by the Corporation is as follows:

         To engage in any lawful act or activity for which corporations may be
organized under the General Corporation Law of Delaware.

         FOURTH: The total number of shares of all classes of stock which the
Corporation shall have authority to issue is 21,000,000 shares, consisting of
(i) 20,000,000 shares of Common Stock, $.01 par value per share ("Common
Stock"), and (ii) 1,000,000 shares of Preferred Stock, $.01 par value per share
("Preferred Stock").

         The following is a statement of the designations and the powers,
privileges and rights, and the qualifications, limitations or restrictions
thereof in 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.

         2.   VOTING. The holders of the Common Stock are entitled to one vote
for each share held at all meetings of stockholders (and written actions in lieu
of meetings). There shall be no cumulative voting.

         The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the Corporation
entitled to vote, irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law of Delaware.

         3.   DIVIDENDS. Dividends may be declared and paid on the Common Stock
from funds lawfully available therefor as and when determined by the Board of
Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

         4.   LIQUIDATION. Upon the dissolution or liquidation of the
Corporation, whether voluntary or involuntary, holders of Common Stock will be
entitled to receive all assets of the Corporation available for distribution to
its 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.




                                       -1-

<PAGE>   2
         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 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 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 perpetual existence.

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

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

         2.   The Board of Directors is expressly authorized to adopt, amend or
              repeal the Bylaws 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. 1. ACTIONS, SUITS AND PROCEEDINGS OTHER THAN BY OR IN THE RIGHT
OF THE CORPORATION. The Corporation shall 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 (other than an action by or in the right of the Corporation), by
reason of the fact that he 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 him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of NOLO CONTENDERE or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful. Notwithstanding
anything to the contrary in this Article, except as set forth in Section 7
below, the Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by the Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation. Notwithstanding anything to the contrary in this Article, 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



                                       -2-


<PAGE>   3
reimbursed from the proceeds of insurance, such Indemnitee shall promptly refund
such indemnification payments to the Corporation to the extent of such insurance
reimbursement.

         2. ACTIONS OR SUITS BY OR IN THE RIGHT OF THE CORPORATION. The
Corporation shall indemnify any Indemnitee who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he 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), or by reason of any
action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees) and, to the extent permitted by law,
amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with such action, suit or proceeding and any appeal
therefrom, if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery of Delaware shall
determine upon application that, despite the adjudication of such liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses (including attorneys' fees)
which the Court of Chancery of Delaware shall deem proper.

         3.   INDEMNIFICATION FOR EXPENSES OF SUCCESSFUL PARTY. Notwithstanding
the other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 1 and 2 of this Article, or in defense of any
claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, he shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by him or on his behalf in connection
therewith. Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an
adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of
guilty or NOLO CONTENDERE by the Indemnitee, (iv) an adjudication that 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, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

         4.   NOTIFICATION AND DEFENSE OF CLAIM. As a condition precedent to his
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. After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such claim,
other than as provided below in this Section 4. The Indemnitee shall have the
right to employ his own counsel in connection with such claim, but the fees and
expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the Corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of counsel for the Indemnitee shall be at the expense of the Corporation, except
as otherwise expressly provided by this Article. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above.






                                      -3-
<PAGE>   4
         5.   ADVANCE OF EXPENSES. Subject to the provisions of Section 6 below,
in the event that the Corporation does not assume the defense pursuant to
Section 4 of this Article of any action, suit, proceeding or investigation of
which the Corporation receives notice under this Article, any expenses
(including attorneys' fees) incurred by an Indemnitee in defending a civil or
criminal action, suit, proceeding or investigation or any appeal therefrom shall
be paid by the Corporation in advance of the final disposition of such matter;
PROVIDED, 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. Such undertaking shall be accepted without reference to the
financial ability of the Indemnitee to make such repayment.

         6.   PROCEDURE FOR INDEMNIFICATION. In order to obtain indemnification
or advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the
Indemnitee shall submit to the Corporation a written request, including in such
request such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to determine whether and to what extent
the Indemnitee is entitled to indemnification or advancement of expenses. Any
such indemnification or advancement of expenses shall be made promptly, and in
any event within 60 days after receipt by the Corporation of the written request
of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the
Corporation determines within such 60-day period that the Indemnitee did not
meet the applicable standard of conduct set forth in Section 1 or 2, as the case
may be. Such determination 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.

         7.   REMEDIES. The right to indemnification or advances as granted by
this Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6. Unless otherwise required by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation. Neither the failure of the Corporation
to have made a determination prior to the commencement of such action that
indemnification is proper in the circumstances because the Indemnitee has met
the applicable standard of conduct, nor an actual determination by the
Corporation pursuant to Section 6 that the Indemnitee has not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that the Indemnitee has not met the applicable standard of conduct.
The Indemnitee's expenses (including attorneys' fees) incurred in connection
with successfully establishing his right to indemnification, in whole or in
part, in any such proceeding shall also be indemnified by the Corporation.

         8.   SUBSEQUENT AMENDMENT. No amendment, termination or repeal of this
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

         9.   OTHER RIGHTS. The indemnification and advancement of expenses
provided by this Article shall not be deemed exclusive of any other rights to
which an Indemnitee seeking indemnification or advancement of expenses may be
entitled under any law (common or statutory), agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in any other capacity while holding office for the
Corporation, and shall continue as to an Indemnitee who has ceased to be a
director or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of the Indemnitee. Nothing contained in this
Article shall be deemed to prohibit, and the Corporation is specifically
authorized to enter into, agreements with officers and directors



                                      -4-
<PAGE>   5
providing indemnification rights and procedures different from those set forth
in this Article. In addition, 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.

         10.  PARTIAL INDEMNIFICATION. If an Indemnitee is entitled under any
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

         11.  INSURANCE. The Corporation may purchase and maintain insurance, at
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) against any expense,
liability or loss incurred by him in any such capacity, or arising out of his
status as such, whether or not the Corporation would have the power to indemnify
such person against such expense, liability or loss under the General
Corporation Law of Delaware.

         12.  MERGER OR CONSOLIDATION. If the Corporation is merged into or
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such merger or consolidation.

         13.  SAVINGS CLAUSE. If this Article or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit, proceeding or investigation, whether civil,
criminal or administrative, including an action by or in the right of the
Corporation, to the fullest extent permitted by any applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

         14.  DEFINITIONS. Terms used herein and defined in Section 145(h) and
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

         15.  SUBSEQUENT LEGISLATION. If the General Corporation Law of Delaware
is amended after adoption of this Article to expand further the indemnification
permitted to Indemnitees, then the Corporation shall indemnify such persons to
the fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

         NINTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute and this Certificate of
Incorporation, and all rights conferred upon stockholders herein are granted
subject to this reservation.



EXECUTED at Quincy, Massachusetts, on July 15, 1998.

   OF THE POWERS, PREFERENCES AND RELATIVE, PARTICIPATING, OPTIONAL AND OTHER
 SPECIAL RIGHTS OF 13-1/2% SERIES A PREFERRED STOCK DUE 2009 AND QUALIFICATIONS,
                      LIMITATIONS AND RESTRICTIONS THEREOF

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

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware

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

         Network Plus Corp. (the "Company"), a corporation organized and
existing under the General Corporation Law of the State of Delaware, does hereby
certify that, pursuant to authority conferred upon the board of directors of the
Corporation (the "Board of Directors") by its Certificate of Incorporation
(hereinafter referred to as the "Certificate of Incorporation"), and pursuant to
the provisions of Section 151 of the General Corporation Law of the State of
Delaware, said Board of Directors, by unanimous written consent dated September
1, 1998, duly approved and adopted the following resolution (the "Resolution"):

         RESOLVED that, pursuant to the authority vested in the Board of
     Directors by its Certificate of Incorporation, the Board of Directors does
     hereby create, authorize and provide for the issuance of 13-1/2% Series A
     Cumulative Preferred Stock due 2009, par value $.01 per share, with a
     stated value initially of $1,000 per share, consisting of 50,000 shares,
     and 13-1/2% Series A1 Cumulative Preferred Stock due 2009, par value $.01
     per share, with a stated value initially of $1,000 per share, consisting of
     50,000 shares having the designations, preferences, relative,
     participating, optional and other special rights and the qualifications,
     limitations and restrictions thereof that are set forth in the Certificate
     of Incorporation and in this Resolution as follows:

         (a) DESIGNATION. There is hereby created out of the authorized and
unissued shares of Preferred Stock of the Company (i) a series of Preferred
Stock designated as the "13-1/2% Series A Cumulative Preferred Stock due 2009"
(the "Class A Stock") and (ii) a series of Preferred Stock designated as the
"13-1/2% Series A1 Cumulative Preferred Stock due 2009" (the "Class A1 Stock").
The number of shares constituting the Class A Stock shall be 50,000, and the
number of shares constituting the Class A1 Stock shall be 50,000. The Class A
Stock and the Class A1 Stock are referred to as the "Series A Preferred Stock".
The liquidation preference of the Series A Preferred Stock shall be $1,000 per
share (the "Liquidation Preference"). "Specified Amount" shall have the meaning
set forth in paragraph (o).

         (b) RANK. The Series A Preferred Stock will, with respect to dividend
rights and rights on liquidation, winding-up and dissolution, rank (i) senior to
all classes of common stock and to each other class of Capital Stock of the
Company or series of Preferred Stock of the Company outstanding on the Issue
Date and each other class or series established hereafter by the Board of
Directors the terms of which do not expressly provide that it ranks senior to,
or on a parity with, the Series A Preferred Stock as to dividend rights and
rights on liquidation, winding-up and dissolution of the Company (collectively
referred to, together with all classes of common stock of the Company, as
"Junior Stock"); (ii) on a parity with each class of Capital Stock of the
Company or series of Preferred Stock of the Company established hereafter by the
Board of Directors, the terms of which expressly provide that such class or
series will rank on a parity with the Series A Preferred Stock as to dividend
rights and rights on liquidation, winding-up and dissolution (collectively
referred to as "Parity Stock"); and (iii) junior to each class of Capital Stock
of the Company or series of Preferred Stock of the Company established hereafter
by the Board of Directors, the terms of which expressly provide that such class
or series will rank senior to the Series A Preferred Stock as to dividend rights
and rights upon liquidation, winding-up and dissolution of the Company
(collectively referred to as "Senior Stock"). While any shares of Series A
Preferred Stock are outstanding, the Company may not authorize, create or
increase the authorized amount of any class or




                                        1

<PAGE>   2
series of stock that ranks senior to or on parity with the Series A Preferred
Stock with respect to the payment of dividends or amounts upon liquidation,
dissolution or winding up without the consent of the Holders of a majority of
the outstanding shares of Series A Preferred Stock. All claims of the Holders of
the Series A Preferred Stock, including without limitation, claims with respect
to dividend payments, redemption payments, mandatory repurchase payments or
rights upon liquidation, winding-up or dissolution, shall rank junior to the
claims of any holders of any debt of the Company and its subsidiaries and all
other creditors of the Company and its subsidiaries.

         (c) DIVIDENDS. (i) Holders of shares of Series A Preferred Stock will
be entitled to receive, when, as and if dividends are declared by the Board of
Directors of the Company out of funds of the Company legally available therefor,
cumulative preferential dividends from the Issue Date at a rate per share of
13-1/2% per annum of the Specified Amount per share of Series A Preferred Stock,
payable quarterly (each such quarterly period being herein called a "Dividend
Period") in arrears on each of March 1, June 1, September 1 and December 1 (each
a "Dividend Payment Date") or, if any such date is not a Business Day, on the
next succeeding Business Day, to the holders of record as of the next preceding
February 15, May 15, August 15 and November 15, respectively. In addition to the
dividends described in the preceding sentence, holders of outstanding shares of
Series A Preferred Stock will be entitled to Additional Dividends if and to the
extent provided for in the Exchange and Registration Rights Agreement. If any
dividend (other than any Additional Dividends) payable on any Dividend Payment
Date on or before September 1, 2003 is not declared or paid in full in cash on
such Dividend Payment Date, the amount payable as dividends on such Dividend
Payment Date (other than any Additional Dividends) that is not paid in cash on
such Dividend Payment Date will be added automatically to the Specified Amount
of the Series A Preferred Stock on such Dividend Payment Date and will be deemed
paid in full (such dividends being herein called the "Accumulated Dividends").
Except as provided herein, accrued and unpaid dividends, if any, will not bear
interest or bear dividends thereon.

         (ii) All dividends paid with respect to shares of the Series A
Preferred Stock pursuant to paragraph (c)(i) shall be paid pro rata to the
holders entitled thereto.

         (iii) Dividends on the Series A Preferred Stock will accrue whether or
not the Company has earnings or profits, whether or not there are funds legally
available for the payment of such dividends and whether or not dividends are
declared. Except as set forth in clause (c)(i) above, dividends will accumulate
to the extent they are not paid on the Dividend Payment Date for the period to
which they relate. The Company will take all actions required or permitted under
the Delaware General Corporation Law to permit the payment of dividends on the
Series A Preferred Stock.

         (iv) No dividend whatsoever shall be declared or paid upon, or any sum
set apart for the payment of dividends upon, any outstanding share of the Series
A Preferred Stock with respect to any dividend period unless all unpaid
dividends for all preceding dividend periods have been added to the Specified
Amount (if on or before September 1, 2003), declared and paid or declared and,
if applicable, a sufficient sum set apart for the payment of such dividend, upon
all outstanding shares of Series A Preferred Stock.

         (v) Except as provided in the next sentence, no dividend will be
declared or paid (or deemed paid) on any Parity Stock unless full cumulative
dividends have been paid on the Series A Preferred Stock for all prior dividend
periods. If accumulated dividends on the Series A Preferred Stock for all prior
dividend periods have not been paid (or deemed paid) in full then any dividend
declared on the Series A Preferred Stock for any dividend period and on any
Parity Stock will be declared ratably in proportion to accrued and unpaid
dividends on the Series A Preferred Stock and such Parity Stock.

         (vi) The Company will not (i) declare, pay or set apart funds for the
payment of any dividend or other distribution with respect to any Junior Stock
or (ii) redeem, purchase or otherwise acquire for consideration any Junior Stock
through a sinking fund or otherwise, unless (A) all accrued and unpaid dividends
with respect to the Series A Preferred Stock and any Parity Stock at the time
such dividends are payable have been paid (or deemed paid) or funds have been
set apart for payment of such dividends and (B) sufficient funds have been paid
or set apart for the payment of



                                        2

<PAGE>   3
the dividend for the current dividend period with respect to the Series A
Preferred Stock and any Parity Stock.

         (vii) Dividends on account of arrears for any past Dividend Period and
dividends in connection with any optional redemption may be declared and paid at
any time, without reference to any regular Dividend Repayment Date, to holders
of record on such date, not more than 45 days prior to the payment thereof, as
may be fixed by the Board of Directors of the Company.

         (viii) Dividends payable on the Series A Preferred Stock shall be
computed on the basis of a 360-day year of twelve 30-day months and will be
deemed to accrue on a daily basis.

         (d) LIQUIDATION PREFERENCE. (i) Upon any voluntary or involuntary
liquidation, dissolution or winding-up of the Company, holders of Series A
Preferred Stock will be entitled to be paid, out of the assets of the Company
available for distribution to its stockholders, the Specified Amount, plus,
without duplication, an amount in cash equal to all accumulated and unpaid
dividends thereon to the date fixed for liquidation, dissolution or winding-up
(including an amount equal to a prorated dividend for the period from the last
Dividend Payment Date to the date fixed for liquidation, dissolution or
winding-up and including an amount equal to the redemption premium that would
have been payable had the Series A Preferred Stock been the subject of an
Optional Redemption on such date) before any distribution is made on any Junior
Stock, including, without limitation, common stock of the Company. If, upon any
voluntary or involuntary liquidation, dissolution or winding up of the Company,
the amounts payable with respect to the Series A Preferred Stock and all Parity
Stock are not paid in full, the Series A Preferred Stock and the Parity Stock
will share equally and ratably in any distribution of assets of the Company to
which each is entitled. After payment of the full amount of the Specified Amount
(and an amount equal to the accumulated and unpaid dividends to which they are
entitled), the holders of shares of Series A Preferred Stock will not be
entitled to any further participation in any distribution of assets of the
Company.

         (ii) For the purposes of this paragraph (d), neither the sale,
conveyance, exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all the property or assets of the Company
nor the consolidation or merger of the Company with or into one or more entities
shall be deemed to be a liquidation, dissolution or winding-up of the Company.

         (e) REDEMPTION. (i) (A) Except as set forth in this paragraph
(e)(i)(A), the Series A Preferred Stock will not be redeemable at the option of
the Company prior to September 1, 2003. Thereafter, the Series A Preferred Stock
will be redeemable, at the Company's option (subject to the legal availability
of funds therefor), 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 (the
"Optional Redemption Price") (expressed as a percentage of the Specified Amount
thereof), plus, without duplication, an amount in cash equal to all accumulated
and unpaid dividends (including Additional Dividends and an amount in cash equal
to a prorated dividend for any partial dividend period) if any, to the date of
redemption (the "Optional Redemption Date") (subject to the rights of holders of
record on the relevant record date to receive dividends due on the relevant
Dividend Payment Date), if redeemed during the 12-month period commencing on
September 1 of the years set forth below:

         (B) In the event of a redemption of only a portion of the then
outstanding shares of Series A Preferred Stock, the Company shall effect such
redemption on a pro rata basis, except that the Company may redeem such shares
held by holders of fewer than 100 shares (or shares held by holders who would
hold less than 100 shares as a result of such redemption), as may be determined
by the Company.

         (ii) MANDATORY REDEMPTION. (A) As soon as practicable following the
closing of a Senior Notes Offering the net proceeds of which (excluding
underwriting or other placement fees and proceeds placed in escrow at the
closing thereof pursuant to the terms of such offering) received by the Company
exceed $100 million, the Company will be required to redeem (subject to the
legal availability of funds therefor) all outstanding shares of Series A
Preferred Stock at a price (the "Notes Redemption Price") in cash equal to 108%
of the Specified Amount thereof, plus, without duplication, an amount in cash
equal to all accumulated and unpaid dividends (including Additional Dividends
and an amount in cash equal to a prorated dividend for any partial dividend
period), if any, to the date of redemption (the "Notes Redemption Date")
(subject to the rights of holders of record on the relevant record date to
receive dividends on the relevant Dividend Payment Date).

         (B) If at any time and from time to time prior to September 1, 2001,
the Company consummates one or more Public Equity Offerings, the Company will be
required to apply the first $25 million of net proceeds (excluding underwriting
or other placement fees and calculated on a cumulative basis beginning with the
first such Public Equity Offering) from such Public Equity Offering or Offerings
and one-half of each additional dollar of net proceeds (excluding underwriting
or other placement fees and calculated on a cumulative basis beginning with the
first such Public Equity Offering) in excess of $25 million to redeem the Series
A Preferred Stock, at the following redemption prices (the "Equity Redemption
Price" and, together with the Notes Redemption Price, the "Mandatory Redemption
Price") (expressed as a percentage of the Specified Amount thereof), plus,
without duplication, an amount in cash equal to all accumulated and unpaid
dividends (including Additional Dividends and an amount in cash equal to a
prorated dividend for any partial dividend period) if any, to the date of
redemption (the "Equity Redemption Date" and, together with the Notes Redemption
Date, the "Mandatory Redemption Date") (subject to the rights of holders of
record on the relevant record date to receive dividends due on the relevant
Dividend Payment Date), if redeemed during the period ending on the dates set
forth below:

         (C) The Company will take all actions required or permitted under
Delaware law to permit a redemption required by this paragraph (e)(ii).

         (D) In the event of a redemption of only a portion of the then
outstanding shares of Series A Preferred Stock, the Company shall effect such
redemption on a pro rata basis, except that the Company may redeem such shares
held by holders of fewer than 100 shares (or shares held by holders who would
hold less than 100 shares as a result of such redemption), as may be determined
by the Company.

         (iii) PROCEDURE FOR REDEMPTION. (A) On and after the Optional
Redemption Date or any Mandatory Redemption Date, as the case may be (the
"Redemption Date"), unless the Company defaults in the payment of the applicable
redemption price, dividends will cease to accumulate on shares of Series A
Preferred Stock called for redemption and all rights of holders of such shares
will terminate except for the right to receive the Optional Redemption Price or
the Mandatory Redemption Price, as the case may be, without interest; PROVIDED,
HOWEVER, that if a notice of redemption shall have been given as provided in
paragraph (iii)(B) below shall not have been given and the funds necessary for
redemption (including an amount in respect of all dividends that will accrue to
the Redemption Date) shall have been segregated and irrevocably set apart by the
Company, in trust for the benefit of the holders of the shares called for
redemption, then dividends shall cease to accumulate on the Redemption Date on
the shares to be redeemed and, at the close of business on the day on which such
funds are segregated and set apart, the holders of the shares to be redeemed
shall cease to be stockholders of the Company and shall be entitled only to
receive the Optional Redemption Price or the Mandatory Redemption Price, as the
case may be, for such shares.



                                        4

<PAGE>   5
         (B) With respect to a redemption pursuant to paragraph e(i) or e(ii),
the Company will send a written notice of redemption by first class mail to each
holder of record of shares of Series A Preferred Stock, not fewer than 30 days
nor more than 60 days prior to the Redemption Date at its registered address
(the "Redemption Notice"); PROVIDED, HOWEVER, that no failure to give such
notice nor any deficiency therein shall affect the validity of the procedure for
the redemption of any shares of Series A Preferred Stock to be redeemed except
as to the holder or holders to whom the Company has failed to give said notice
or except as to the holder or holders whose notice was defective. The Redemption
Notice shall state:

         (1) whether the redemption is pursuant to paragraph (e)(i) or (e)(ii)
     hereof;

         (2) the Optional Redemption Price or the Mandatory Redemption Price, as
     the case may be;

         (3) whether all or less than all the outstanding shares of the Series A
     Preferred Stock are to be redeemed and the total number of shares of the
     Series A Preferred Stock being redeemed;

         (4) the Redemption Date;

         (5) that the holder is to surrender to the Company, in the manner, at
     the place or places and at the price designated, his certificate or
     certificates representing the shares of Series A Preferred Stock to be
     redeemed; and

         (6) that dividends on the shares of the Series A Preferred Stock to be
     redeemed shall cease to accumulate on such Redemption Date unless the
     Company defaults in the payment of the Optional Redemption Price or the
     Mandatory Redemption Price, as the case may be.

         (C) Each holder of Series A Preferred Stock shall surrender the
certificate or certificates representing such shares of Series A Preferred Stock
to the Company, duly endorsed (or otherwise in proper form for transfer, as
determined by the Company), in the manner and at the place designated in the
Redemption Notice, and on the Redemption Date the full Optional Redemption Price
or Mandatory Redemption Price, as the case may be, for such shares shall be
payable in cash to the person whose name appears on such certificate or
certificates as the owner thereof, and each surrendered certificate shall be
canceled and retired. In the event that less than all of the shares represented
by any such certificate are redeemed, a new certificate shall be issued
representing the unredeemed shares.

         (f) VOTING RIGHTS. (i) The holders of Series A Preferred Stock, except
as otherwise required under Delaware law or as set forth in paragraphs (ii) and
(iii) below, shall not be entitled or permitted to vote on any matter required
or permitted to be voted upon by the stockholders of the Company.

         (ii) (A) If (1) after September 1, 2003, dividends on the Series A
Preferred Stock are in arrears and unpaid for six or more Dividend Periods
(whether or not consecutive) (a "Dividend Default"); (2) the Company fails to
redeem the Series A Preferred Stock on September 1, 2009, or fails to otherwise
discharge any redemption obligation with respect to the Series A Preferred
Stock; (3) the Company fails to make an Offer to Purchase if such Offer to
Purchase is required by paragraph (h) hereof or fails to purchase shares of
Series A Preferred Stock from holders who elect to have such shares purchased
pursuant to such Offer to Purchase; (4) a breach or violation of any of the
provisions set forth in paragraph (l) hereof occurs and the breach or violation
continues for a period of 60 days or more after the Company receives notice
thereof specifying the default from the holders of at least 25% of the shares of
Series A Preferred Stock then outstanding; or (5) the Company fails to pay at
final maturity (giving effect to any applicable grace period) the principal
amount of any Debt of the Company or any Significant Subsidiary of the Company,
or the final stated maturity of any such Debt is accelerated because of a
default and the total amount of such Debt unpaid or accelerated exceeds $10
million and such nonpayment continues, or such acceleration is not rescinded or
waived within 10 days, then the number of directors constituting the Board of
Directors of the Company will be adjusted to permit the holders of a majority of
the then outstanding shares of Series A Preferred Stock, voting separately and
as a class, to elect the lesser of two directors and that number of directors
constituting 25% of the members of the Board of Directors. Each



                                        5

<PAGE>   6
such event described in clauses (1), (2), (3), (4) and (5) above is a "Voting
Rights Triggering Event".

         (B) The voting rights set forth in subparagraph (f)(ii)(A) above will
continue until such time as (x) in the case of a Dividend Default, all dividends
in arrears on the Series A Preferred Stock are paid in full in cash, and (y) in
all other cases, any failure, breach or default giving rise to such Voting
Rights Triggering Event is remedied or waived by the holders of a majority of
the shares of Series A Preferred Stock then outstanding, at which time the term
of any directors elected pursuant to the provisions of subparagraph (f)(ii)(A)
above shall terminate. At any time after voting power to elect directors shall
have become vested and be continuing in the holders of Series A Preferred Stock
pursuant to subparagraph (f)(ii)(A) hereof, or if vacancies shall exist in the
offices of directors elected by the holders of Series A Preferred Stock, a
proper officer of the Company may, and upon the written request of the holders
of record of at least 25% of the shares of Series A Preferred Stock then
outstanding addressed to the secretary of the Company shall, call a special
meeting of the holders of Series A Preferred Stock for the purpose of electing
the directors which such holders are entitled to elect. If such meeting shall
not be called by a proper officer of the Company within 20 days after personal
service to the secretary of the Company at its principal executive offices, then
the holders of record of at least 25% of the outstanding shares of Series A
Preferred Stock may designate in writing one of their number to call such
meeting at the expense of the Company, and such meeting may be called by the
person so designated upon the notice required for the annual meetings of
stockholders of the Company and shall be held at the place for holding the
annual meetings of stockholders. Any holder of Series A Preferred Stock so
designated shall have, and the Company shall provide, access to the lists of
stockholders to be called pursuant to the provisions hereof.

         (C) At any meeting held for the purposes of electing directors at which
the holders of Series A Preferred Stock shall have the right, voting together as
a separate class, to elect directors as aforesaid, the presence in person or by
proxy of the holders of at least a majority of the outstanding shares of Series
A Preferred Stock shall be required to constitute a quorum of such Series A
Preferred Stock.

         (D) Any vacancy occurring in the office of a director elected by the
holders of Series A Preferred Stock may be filled by the remaining directors
elected by the holders of Series A Preferred Stock unless and until such vacancy
shall be filled by the holders of Series A Preferred Stock. The director to be
elected by the holders of Series A Preferred Stock shall agree, prior to his
election to office, to resign upon any termination of the right of the holders
of Series A Preferred Stock to vote as a class for a director as herein
provided, and upon any such termination the director then in office elected by
the holders of Series A Preferred Stock shall forthwith resign.

         (iii) (A) So long as any shares of the Series A Preferred Stock are
outstanding, the Company will not authorize any class of Senior Stock without
the affirmative vote or consent of holders of at least a majority of the shares
of Series A Preferred Stock then outstanding, voting or consenting, as the case
may be, as one class, given in person or by proxy, either in writing or by
resolution adopted at an annual or special meeting. So long as any shares of the
Series A Preferred Stock are outstanding, the Company will not authorize the
issuance of any additional shares of Series A Preferred Stock without the
affirmative vote or consent of the holders of at least a majority of the then
outstanding shares of Series A Preferred Stock, voting or consenting, as the
case may be, as one class, given in person or by proxy, either in writing or by
resolution adopted at an annual or special meeting.

         (B) So long as any shares of the Series A Preferred Stock are
outstanding, the Company will not amend this Certificate of Designation so as to
affect adversely the specified rights, preferences, privileges or voting rights
of holders of shares of Series A Preferred Stock or to authorize the issuance of
any additional shares of Series A Preferred Stock without the affirmative vote
or consent of holders of at least two-thirds of the issued and outstanding
shares of Series A Preferred Stock, voting or consenting, as the case may be, as
one class, given in person or by proxy, either in writing or by resolution
adopted at an annual or special meeting.

         (C) Except as set forth in paragraph (f)(iii)(A) above, (x) the
creation, authorization or issuance of any shares of any Junior Stock or Parity
Stock,



                                        6

<PAGE>   7
including the designation of a series thereof within the existing class of
Series A Preferred Stock, or (y) the increase or decrease in the amount of
authorized Capital Stock of any class, including Preferred Stock, shall not
require the consent of holders thereof within the existing class of Series A
Preferred Stock and shall not be deemed to affect adversely the rights,
preferences, privileges or voting rights of shares of Series A Preferred Stock.

         (iv) In any case in which the holders of Series A Preferred Stock shall
be entitled to vote pursuant to this paragraph (f) or pursuant to Delaware law,
each holder of Series A Preferred Stock entitled to vote with respect to such
matters shall be entitled to one vote for each share of Series A Preferred Stock
held.

         (g) EXCHANGE OF CLASS A1 STOCK FOR CLASS A STOCK. The Class A1 Stock
will be issued by the Company only in connection with an exchange offer, on a
share for share basis, for the Class A Stock as required pursuant to the
Exchange and Registration Rights Agreement. Each share of Class A1 Stock issued
in exchange for a share of Class A Stock will be deemed to have the same
Specified Amount as the share of Class A Stock so exchanged.

         (h) CHANGE OF CONTROL. (i) Within 30 days of the occurrence of a Change
of Control, the Company shall make an Offer to Purchase all outstanding shares
of Series A Preferred Stock at a purchase price equal to 101% of the Specified
Amount thereof plus, without duplication, an amount in cash equal to all
accumulated and unpaid dividends (including all Additional Dividends and an
amount in cash equal to a prorated dividend for any partial Dividend Period), if
any, to the date of purchase (subject to the rights of holders of record on the
relevant record date to receive dividends due on the relevant dividend payment
date).

         (ii) The Company will comply with any tender offer rules under the
Exchange Act which then may be applicable, including Rules 13e-4 and 14e-1, in
connection with any offer required to be made by the Company to repurchase the
shares of Series A Preferred Stock as a result of a Change of Control. To the
extent that the provisions of any securities laws or regulations conflict with
provisions of this Certificate of Designation, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Certificate of Designation by virtue
thereof.

         (iii) On the Purchase Date the Company shall (A) accept for payment the
shares of Series A Preferred Stock validly tendered pursuant to the Offer to
Purchase, (B) pay to the holders of shares so accepted the purchase price
therefor in cash and (C) cancel and retire each surrendered certificate. Unless
the Company defaults in the payment for the shares of Series A Preferred Stock
tendered pursuant to the Offer to Purchase required by this paragraph (h),
dividends will cease to accrue with respect to the shares of Series A Preferred
Stock tendered and all rights of holders of such tendered shares will terminate,
except for the right to receive payment therefor, on the Purchase Date.

         (i) CONVERSION OR EXCHANGE. The holders of shares of Series A Preferred
Stock shall not have any rights hereunder to convert such shares into or
exchange such shares for shares of any other class or classes or of any other
series of any class or classes of Capital Stock of the Company.

         (j) REISSUANCE OF SERIES A PREFERRED STOCK. Shares of Series A
Preferred Stock that have been issued and reacquired in any manner, including
shares purchased or redeemed or exchanged, shall (upon compliance with any
applicable provisions of the laws of Delaware) have the status of authorized and
unissued shares of Preferred Stock undesignated as to series and may be
redesignated and reissued as part of any series of Preferred Stock; PROVIDED,
HOWEVER, that so long as any shares of Series A Preferred Stock are outstanding,
any issuance of such shares must be in compliance with the terms hereof.

         (k) BUSINESS DAY. If any payment, redemption or exchange shall be
required by the terms hereof to be made on a day that is not a Business Day,
such payment, redemption or exchange shall be made on the immediately succeeding
Business Day.

         (l) CERTAIN ADDITIONAL PROVISIONS. The Company covenants and agrees for
the benefit of the Holders as follows:



                                        7

<PAGE>   8
         (i) LIMITATION ON DEBT. (A) The Company may not, and may not permit any
Restricted Subsidiary of the Company to, Incur any Debt unless the ratio of (i)
the aggregate consolidated principal amount of Debt of the Company and its
Restricted Subsidiaries outstanding as of the most recent available quarterly or
annual balance sheet, after giving pro forma effect to the Incurrence of such
Debt and any other Debt Incurred since such balance sheet date and the receipt
and application of the proceeds thereof to (ii) Consolidated Cash Flow Available
for Fixed Charges for the four full fiscal quarters next preceding the
Incurrence of such Debt for which consolidated financial statements are
available, determined on a pro forma basis as if any such Debt had been Incurred
at the beginning of such four fiscal quarters, would be less than 7.0 to 1 for
such four-quarter periods ending on or prior to September 1, 2000, and 5.0 to 1
for such periods ending thereafter.

         (B) Notwithstanding the foregoing paragraph (A), the Company and any
Restricted Subsidiary (except as specified below) may Incur any or all of the
following:

         (i) Debt outstanding on the Issue Date;

         (ii) Debt under any Bank Credit Agreement;

         (iii) Purchase Money Debt Incurred to finance the construction,
     acquisition, development, design, installation, integration, transportation
     or improvement of Telecommunications Assets which, together with any other
     outstanding Debt Incurred pursuant to this clause (iii) and any Debt
     Incurred pursuant to clause (vi) of this paragraph (B) in respect of Debt
     Incurred pursuant to this clause (iii), has an aggregate principal amount
     at the time of Incurrence, not in excess of $100 million at any time
     outstanding;

         (iv) Senior Notes the offering of which, together with any other
     outstanding Debt Incurred pursuant to this clause (iv), resulted in net
     proceeds (excluding underwriting or other placement fees and proceeds
     placed in escrow at the closing thereof pursuant to the terms of such
     offering) to the Company, not in excess of $100 million;

         (v) Debt owed by the Company to any Restricted Subsidiary of the
     Company or Debt owed by a Restricted Subsidiary of the Company to the
     Company or a Restricted Subsidiary of the Company; PROVIDED, HOWEVER, that
     upon either (x) the transfer or other disposition by such Restricted
     Subsidiary or the Company of any Debt so permitted to a Person other than
     the Company or another Restricted Subsidiary of the Company or (y) the
     issuance (other than directors' qualifying shares), sale, lease, transfer
     or other disposition of shares of Capital Stock (including by consolidation
     or merger) of such Restricted Subsidiary to a Person other than the Company
     or another such Restricted Subsidiary, the provisions of this clause (v)
     shall no longer be applicable to such Debt and such Debt shall be deemed to
     have been Incurred at the time of such transfer or other disposition;

         (vi) Debt Incurred to renew, extend, refinance or refund (each, a
     "refinancing") (A) Debt outstanding on the Issue Date, (B) Debt Incurred
     pursuant to paragraph (A) of this covenant or (C) Debt Incurred pursuant to
     clause (iii) of this paragraph (b), in each case in an aggregate principal
     amount not to exceed the aggregate principal amount of and accrued interest
     on the Debt so refinanced plus the amount of any premium required to be
     paid in connection with such refinancing pursuant to the terms of the Debt
     so refinanced or the amount of any premium reasonably determined by the
     Company as necessary to accomplish such refinancing by means of a tender
     offer or privately negotiated repurchase, plus the amount of expenses of
     the Company incurred in connection with such refinancing; PROVIDED,
     HOWEVER, that the refinancing Debt by its terms, or by the terms of any
     agreement or instrument pursuant to which such Debt is issued, (x) does not
     provide for payments of principal of such Debt at the stated maturity
     thereof or by way of a sinking fund applicable thereto or by way of any
     mandatory redemption, defeasance, retirement or repurchase thereof by the
     Company (including any redemption, retirement or repurchase which is
     contingent upon events or circumstances, but excluding any retirement
     required by virtue of acceleration of such Debt upon any event of default
     thereunder), in each case prior to the time the same are required by the
     terms of the Debt being refinanced and (y) does not permit redemption or
     other retirement (including

     being refinanced, other than a redemption or other retirement at the option
     of the holder of such Debt (including pursuant to an offer to purchase made

     credit obtained to secure such performance;

         (ix) Debt of the Company to Robert T. Hale, Jr. in an original

     full of all accumulated dividends on the Series A Preferred Stock; and

         (x) Debt of the Company or any Restricted Subsidiary not otherwise
     permitted to be Incurred pursuant to clauses (i) through (viii) above,

         (C) Notwithstanding any other provision of this paragraph (l)(i), the
maximum amount of Debt that the Company or a Restricted Subsidiary may Incur
pursuant to this paragraph (l)(i) shall not be deemed to be exceeded, with
respect to any outstanding Debt, due solely to the result of fluctuations in

         (D) For purposes of determining compliance with this paragraph (l)(i),
in the event that an item of Debt meets the criteria of more than one of the

such covenant, Guarantees or Liens with respect to letters of credit supporting
Debt otherwise included in the determination of a particular amount shall not be
included.

         (ii) LIMITATION ON RESTRICTED PAYMENTS. (A) The Company (i) may not,

         (B) Notwithstanding the foregoing paragraph (l)(ii)(A), (i) the Company
may pay any dividend on Capital Stock of any class within 60 days after the

could have paid such dividend in accordance with the foregoing provisions; (ii)
the Company may repurchase any shares of its Common Stock or options to acquire
its Common Stock from Persons who are currently or were formerly directors,

(other than Disqualified Stock) of the Company; and (v) the Company may pay the
dividend of $5 million declared on July 15, 1998. If the Company makes a
Restricted Payment which, at the time of the making of such Restricted Payment,
would in the good faith determination of the Company be permitted under the
Certificate of Designation, such Restricted Payment shall be deemed to have been
made in compliance with the Certificate of Designation notwithstanding any
subsequent adjustments made in good faith to the Company financial statements
affecting Consolidated Cash Flow Available for Fixed Charges or Consolidated
Interest Expense for any period.

         (iii) LIMITATION ON ASSET DISPOSITIONS. The Company may not, and may
not permit any Restricted Subsidiary to, make any Asset Disposition in one or
more related transactions occurring within any 12-month period unless: (i) the
Company or the Restricted Subsidiary, as the case may be, receives consideration
for such disposition at least equal to the fair market value for the assets sold
or disposed of as determined by management of the Company in good faith, which
determination shall be conclusive; (ii) at least 75% of the consideration for
such disposition consists of (1) cash or readily marketable cash equivalents or

first, to the permanent repayment or reduction of Debt (other than Disqualified
Stock) of the Company or Debt (other than Disqualified Stock) of a Restricted
Subsidiary of the Company, to the extent permitted under the terms thereof and

to Purchase outstanding shares of Series A Preferred Stock at 100% of the
Specified Amount thereof plus, without duplication, an amount in cash equal to
all accumulated and unpaid dividends (including all Additional Dividends and an
amount equal to a prorated dividend for any partial Dividend Period), if any, to
the date of purchase (subject to the rights of holders of record on the relevant
record date to receive dividends due on the relevant dividend payment date),
and, to the extent required by the terms thereof, any other Parity Stock of the
Company at a price no greater than 100% of the liquidation preference thereof
plus accumulated dividends to the date of purchase. To the extent any Net
Available Proceeds remain after such uses, the Company and its Restricted
Subsidiaries may use such amounts for any purposes not prohibited by the
Certificate of Designation. Notwithstanding the foregoing, these provisions



                                       10

<PAGE>   11
shall not apply to any Asset Disposition which constitutes a transfer,
conveyance, sale, lease or other disposition of all or substantially all the
Company's properties or assets as described under paragraph (l)(vi) below.

         (iv) TRANSACTIONS WITH AFFILIATES AND RELATED PERSONS. The Company may
not, and may not permit any Restricted Subsidiary of the Company to, enter into
any transaction (or series of related transactions) with an Affiliate or Related
Person of the Company (other than the Company or a Restricted Subsidiary of the
Company), including any Investment, either directly or indirectly, unless such
transaction is on terms no less favorable to the Company or such Restricted
Subsidiary than those that could be obtained in a comparable arm's-length
transaction with an entity that is not an Affiliate or Related Person and is in
the best interests of such Company or such Restricted Subsidiary. For any
transaction that involves in excess of $1 million but less than or equal to $5
million, the Chief Executive Officer of the Company or a majority of the
disinterested members of the Board of Directors shall determine that the
transaction satisfies the above criteria. For any transaction that involves in
excess of $5 million but less than or equal to $10 million, a majority of the
disinterested members of the Board of Directors of the Company shall determine
that the transaction satisfies the above criteria. For any transaction that
involves in excess of $10 million, the Company shall also obtain an opinion from
a nationally recognized investment banking or accounting firm or another
nationally recognized expert with experience in appraising the terms and
conditions, taken as a whole, of the type of transaction (or series of related
transactions) for which the opinion is required stating that such transaction
(or series of related transactions) is on terms and conditions, taken as a
whole, no less favorable to the Company or such Restricted Subsidiary than those
that could be obtained in a comparable arm's-length transaction with an entity
that is not an Affiliate or Related Person of the Company, which opinion shall
be available for inspection by holders of Series A Preferred Stock at the
Company's offices. This covenant shall not apply to Investments by an Affiliate
or a Related Person of the Company in the Capital Stock (other than Disqualified
Stock) of the Company or any Restricted Subsidiary of the Company.

         (v) PROVISION OF FINANCIAL INFORMATION. The Company has agreed that,
for so long as any Series A Preferred Stock remains outstanding, it will furnish
to the holders of the Series A Preferred Stock and to securities analysts and
prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act. In addition,
prior to the effectiveness of the Exchange Offer Registration Statement, the
Company will furnish to the holders of the Series A Preferred Stock the
quarterly and annual financial statements and related notes and an accompanying
Management's Discussion and Analysis of Financial Condition and Results of
Operations in the format that would be required to be included in the Company's
periodic reports filed with the Commission if the Company were required to file
such reports with the Commission. The Company will furnish such information to
the holders of the Series A Preferred Stock within 15 days after the date on
which the Company would have been required to file the same with the Commission.
Following the effectiveness of the Exchange Offer Registration Statement (or
earlier if the Company becomes obligated to file reports with the Commission),
the Company will furnish to the holders of the Series A Preferred Stock within
15 days after it files them with the Commission copies of the annual and
quarterly reports and the information, documents, and other reports that the
Company is required to file with the Commission pursuant to Section 13(a) or
15(d) of the Exchange Act ("SEC Reports"). In the event the Company shall cease
to be required to file SEC Reports pursuant to the Exchange Act, the Company
will nevertheless continue to file such reports with the Commission (unless the
Commission will not accept such a filing) and furnish such reports to the
holders of Series A Preferred Stock. The Company will make copies of the SEC
Reports available to investors who request them in writing.

         (vi) MERGERS, CONSOLIDATIONS AND CERTAIN SALES OF ASSETS. The Company
may not, in a single transaction or a series of related transactions, (i)
consolidate with or merge into any other Person or permit any other Person to
consolidate with or merge into the Company (other than the consolidation or
merger of a Restricted Subsidiary organized under the laws of a State of the
United States into the Company), or (ii) directly or indirectly, transfer, sell,
lease or otherwise dispose of all or substantially all its assets (determined on
a consolidated basis for the Company and its Restricted Subsidiaries taken as a
whole), unless: (1) in a transaction in which the Company does not survive or in
which the Company sells, leases or otherwise disposes of all or substantially
all its assets to any other Person, the successor entity to the Company is
organized under the laws of the United States of America or



                                       11

<PAGE>   12
any State thereof or the District of Columbia and the Series A Preferred Stock
shall be converted into or exchanged for and shall become shares of such
successor entity, having in respect of such successor entity the same powers,
preferences and relative participating, optional or other special rights and the
qualifications, limitations or restrictions thereon, that the Series A Preferred
Stock had immediately prior to such transaction; (2) immediately after giving
pro forma effect to such transaction as if such transaction had occurred at the
beginning of the last full fiscal quarter immediately prior to the consummation
of such transaction with the appropriate adjustments with respect to the
transaction being included in such pro forma calculation and treating any Debt
which becomes an obligation of the Company or a Subsidiary as a result of such
transaction as having been Incurred by the Company or such Subsidiary at the
time of the transaction, no Voting Rights Triggering Event, and no event that
after the giving of notice or lapse of time or both would become a Voting Rights
Triggering Event, shall have occurred and be continuing; (3) immediately after
giving effect to such transaction, the Consolidated Net Worth of the Company (or
the successor entity to the Company) is equal to or greater than that of the
Company immediately prior to the transaction; (4) immediately after giving
effect to such transaction, the Company (or the successor entity to the Company)
would be able to incur an additional $1.00 of Debt under paragraph (l)(i)(A)
above; and (5) the Company has caused to be delivered to the holders of the
Series A Preferred Stock an Opinion of Counsel to the effect that the holders of
the Series A Preferred Stock will not recognize gain or loss for Federal income
tax purposes as a result of such transaction.

         In the event of any transaction (other than a lease) described in and
complying with the immediately preceding paragraph in which the Company is not
the surviving person and the surviving person complies with clause (1) of the
preceding paragraph, such surviving person shall succeed to, and be substituted
for, and may exercise every right and power of, the Company, and the Company
will be discharged from its obligations under the Series A Preferred Stock and
the Certificate of Designation; PROVIDED that solely for the purpose of
calculating amounts described in clause (3) of paragraph (l)(ii)(A) above, any
such surviving person shall only be deemed to have succeeded to and be
substituted for the Company with respect to the period subsequent to the
effective time of such transaction, and the Company (before giving effect to
such transaction) shall be deemed to be the "Company" for such purposes for all
prior periods.

         (m) CERTIFICATES. (i) FORM AND DATING. The Class A Stock and the
Transfer Agent's certificate of authentication shall be substantially in the
form of Exhibit A, which is hereby incorporated in and expressly made a part of
this Certificate of Designation. The Class A1 Stock and the Transfer Agent's
certificate of authentication shall be substantially in the form of Exhibit A;
PROVIDED, HOWEVER, that any reference to Class A shall be replaced with
references to Class A1 and shares of Class A1 Series A Preferred Stock need not
include references to the Exchange and Registration Rights Agreement or legends
applicable to Transfer Restricted Securities. The Series A Preferred Stock
certificate may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Company). Each Series A Preferred Stock certificate shall be dated the
date of its authentication. The terms of the Series A Preferred Stock
certificate set forth in Exhibit A are part of the terms of this Certificate of
Designation.

         (A) GLOBAL SERIES A PREFERRED STOCK. Class A Stock shall be issued
initially in the form of one or more fully registered global certificates with
the global securities legend and restricted securities legend set forth in
Exhibit A hereto (the "Global Series A Preferred Stock"), which shall be
deposited on behalf of the purchasers represented thereby with DTC (or with such
custodian as DTC may direct), and registered in the name of DTC or a nominee of
DTC, duly executed by the Company and authenticated by the Transfer Agent as
hereinafter provided. The number of shares of Series A Preferred Stock
represented by Global Series A Preferred Stock may from time to time be
increased or decreased by adjustments made on the records of the Transfer Agent
and DTC or its nominee as hereinafter provided.

         (B) BOOK-ENTRY PROVISIONS. In the event Global Series A Preferred Stock
is deposited with or on behalf of DTC, the Company shall execute and the
Transfer Agent shall authenticate and deliver initially one or more Global
Series A Preferred Stock certificates that (a) shall be registered in the name
of DTC for such Global Series A Preferred Stock or the nominee of DTC and (b)
shall be delivered by the



                                       12

<PAGE>   13
Transfer Agent to DTC or pursuant to DTC's instructions or held by the Transfer
Agent as custodian for DTC.

         Members of, or participants in, DTC ("Agent Members") shall have no
rights under this Certificate of Designation with respect to any Global Series A
Preferred Stock held on their behalf by DTC or by a custodian of DTC or under
such Global Series A Preferred Stock, and DTC may be treated by the Company, the
Transfer Agent and any agent of the Company or the Transfer Agent as the
absolute owner of such Global Series A Preferred Stock for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Transfer Agent or any agent of the Company or the Transfer Agent
from giving effect to any written certification, proxy or other authorization
furnished by DTC or impair, as between DTC and its Agent Members, the operation
of customary practices of DTC governing the exercise of the rights of a holder
of a beneficial interest in any Global Series A Preferred Stock.

         (C) CERTIFICATED SERIES A PREFERRED STOCK. Except as provided in this
paragraph (i) or in paragraph (iii), owners of beneficial interests in Global
Series A Preferred Stock will not be entitled to receive physical delivery of
certificated Series A Preferred Stock ("Certificated Series A Preferred Stock").

         After a transfer of any Class A Stock during the period of the
effectiveness of a Shelf Registration Statement with respect to such Class A
Stock, all requirements pertaining to legends on such Class A Stock will cease
to apply, the requirements requiring any such Class A Stock issued to Holders be
issued in global form will cease to apply, and Certificated Series A Preferred
Stock without legends will be available to the transferee of the Holder of such
Class A Stock upon exchange of such transferring Holder's Class A Stock or
directions to transfer such Holder's interest in the Global Series A Preferred
Stock, as applicable. Upon the consummation of a Registered Exchange Offer with
respect to the Class A Stock pursuant to which Holders of such Class A Stock are
offered Class A1 Stock in exchange for their Class A Stock, all requirements
that Class A Stock be issued in global form will cease to apply and Certificated
Series A Preferred Stock with the restricted securities legend set forth in
Exhibit A hereto will be available to Holders of such Class A Stock that do not
exchange their Class A Stock, and Class A1 Stock in certificated form will be
available to Holders that exchange such Class A Stock in such Registered
Exchange Offer.

         (ii) EXECUTION AND AUTHENTICATION. Two Officers shall sign the Series A
Preferred Stock for the Company by manual or facsimile signature. If required by
Delaware law, the Company's seal shall be impressed, affixed, imprinted or
reproduced on the Series A Preferred Stock and may be in facsimile form.

         If an Officer whose signature is on Series A Preferred Stock no longer
holds that office at the time the Transfer Agent authenticates the Series A
Preferred Stock, the Series A Preferred Stock shall be valid nevertheless.

         An Series A Preferred Stock shall not be valid until an authorized
signatory of the Transfer Agent manually signs the certificate of authentication
on the Series A Preferred Stock. The signature shall be conclusive evidence that
the Series A Preferred Stock has been authenticated under this Certificate of
Designation.

         The Transfer Agent shall authenticate and deliver: (1) 40,000 shares of
Class A Stock for original issue and (2) 40,000 shares of Class A1 Stock for
issue only in a Registered Exchange Offer pursuant to the Exchange and
Registration Rights Agreement, in each case 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 number of
shares of Series A Preferred Stock to be authenticated and the date on which the
original issue of Series A Preferred Stock is to be authenticated and whether
the Series A Preferred Stock is to be Class A Stock or Class A1 Stock.

         The Transfer Agent may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Series A Preferred Stock. Unless
limited by the terms of such appointment, an authenticating agent may
authenticate Series A Preferred Stock whenever the Transfer Agent may do so.
Each reference in this Certificate of Designation to authentication by the
Transfer Agent includes authentication by such agent. An authenticating agent
has the same rights as the Transfer Agent or agent for service of notices and
demands.

         (iii) TRANSFER AND EXCHANGE. (A) TRANSFER AND EXCHANGE OF CERTIFICATED
SERIES A PREFERRED STOCK. When Certificated Series A Preferred Stock is
presented to the Transfer Agent with a request to register the transfer of such
Certificated Series A Preferred Stock or to exchange such Certificated Series A
Preferred Stock for an equal number of shares of Certificated Series A Preferred
Stock of other authorized denominations, the Transfer Agent shall register the
transfer or make the exchange as requested if its reasonable requirements for
such transaction are met; PROVIDED, HOWEVER, that the Certificated Series A
Preferred Stock surrendered for transfer or exchange:

         (1) shall be duly endorsed or accompanied by a written instrument of
     transfer in form reasonably satisfactory to the Company and the Transfer
     Agent, duly executed by the Holder thereof or his attorney duly authorized
     in writing; and

         (2) in the case of Transfer Restricted Securities that are Certificated
     Series A Preferred Stock, are being transferred or exchanged pursuant to an
     effective registration statement under the Securities Act or pursuant to
     clause (I) or (II) below, and are accompanied by the following additional
     information and documents, as applicable:

              (I) if such Transfer Restricted Securities are being delivered to
         the Transfer Agent by a Holder for registration in the name of such
         Holder, without transfer, a certification from such Holder to that
         effect in substantially the form of Exhibit C hereto; or

              (II) if such Transfer Restricted Securities are being transferred
         to the Company or to a "qualified institutional buyer" ("QIB") in
         accordance with Rule 144A under the Securities Act or pursuant to an
         exemption from registration in accordance with Rule 144 under the
         Securities Act, a certification to that effect (in substantially the
         form of Exhibit B hereto).

         (B) RESTRICTIONS ON TRANSFER OF CERTIFICATED SERIES A PREFERRED STOCK
FOR A BENEFICIAL INTEREST IN GLOBAL SERIES A PREFERRED STOCK. Certificated
Series A Preferred Stock may not be exchanged for a beneficial interest in
Global Series A Preferred Stock except upon satisfaction of the requirements set
forth below. Upon receipt by the Transfer Agent of Certificated Series A
Preferred Stock, duly endorsed or accompanied by appropriate instruments of
transfer, in form satisfactory to the Transfer Agent, together with:

         (1) if such Certificated Series A Preferred Stock is a Transfer
     Restricted Security, certification that such Certificated Series A
     Preferred Stock is being transferred to a QIB in accordance with Rule 144A
     under the Securities Act; and

         (2) whether or not such Certificated Series A Preferred Stock is a
     Transfer Restricted Security, written instructions directing the Transfer
     Agent to make, or to direct DTC to make, an adjustment on its books and
     records with respect to such Global Series A Preferred Stock to reflect an
     increase in the number of shares of Series A Preferred Stock represented by
     the Global Series A Preferred Stock,

then the Transfer Agent shall cancel such Certificated Series A Preferred Stock
and cause, or direct DTC to cause, in accordance with the standing instructions
and procedures existing between DTC and the Transfer Agent, the number of shares
of Series A Preferred Stock represented by the Global Series A Preferred Stock
to be increased accordingly. If no Global Series A Preferred Stock is then
outstanding, the Company shall issue and the Transfer Agent shall authenticate,
upon written order of the Company in the form of an Officers' Certificate, a new
Global Series A Preferred Stock representing the appropriate number of shares.

         (C) TRANSFER AND EXCHANGE OF GLOBAL SERIES A PREFERRED STOCK. The
transfer and exchange of Global Series A Preferred Stock or beneficial interests
therein shall be effected through DTC, in accordance with this Certificate of
Designation (including applicable restrictions on transfer set forth herein, if
any) and the procedures of DTC therefor.



                                       14

<PAGE>   15
         (D) TRANSFER OF A BENEFICIAL INTEREST IN GLOBAL SERIES A PREFERRED
STOCK FOR A CERTIFICATED SERIES A PREFERRED STOCK. (1) Any person having a
beneficial interest in Series A Preferred Stock that is being transferred or
exchanged pursuant to an effective registration statement under the Securities
Act or pursuant to clause (I) or (II) below may upon request, and if accompanied
by the information specified below, exchange such beneficial interest for
Certificated Series A Preferred Stock representing the same number of shares of
Series A Preferred Stock. Upon receipt by the Transfer Agent of written
instructions or such other form of instructions as is customary for DTC from DTC
or its nominee on behalf of any person having a beneficial interest in Global
Series A Preferred Stock and upon receipt by the Transfer Agent of a written
order or such other form of instructions as is customary for DTC or the person
designated by DTC as having such a beneficial interest in a Transfer Restricted
Security only, the following additional information and documents (all of which
may be submitted by facsimile):

              (I) if such beneficial interest is being transferred to the person
         designated by DTC as being the owner of a beneficial interest in Global
         Series A Preferred Stock, a certification from such person to that
         effect (in substantially the form of Exhibit C hereto); or

              (II) if such beneficial interest is being transferred to a QIB in
         accordance with Rule 144A under the Securities Act or pursuant to an
         exemption from registration in accordance with Rule 144 under the
         Securities Act, a certification to that effect (in substantially the
         form of Exhibit B hereto);

then, the Transfer Agent or DTC, at the direction of the Transfer Agent, will
cause, in accordance with the standing instructions and procedures existing
between DTC and the Transfer Agent, the number of shares of Series A Preferred
Stock represented by Global Series A Preferred Stock to be reduced on its books
and records and, following such reduction, the Company will execute and the
Transfer Agent will authenticate and deliver to the transferee Certificated
Series A Preferred Stock.

         (2) Certificated Series A Preferred Stock issued in exchange for a
     beneficial interest in a Global Series A Preferred Stock pursuant to this
     paragraph (iii)(D) shall be registered in such names and in such authorized
     denominations as DTC, pursuant to instructions from its direct or indirect
     participants or otherwise, shall instruct the Transfer Agent. The Transfer
     Agent shall deliver such Certificated Series A Preferred Stock to the
     persons in whose names such Series A Preferred Stock are so registered in
     accordance with the instructions of DTC.

         (E) RESTRICTIONS ON TRANSFER AND EXCHANGE OF GLOBAL SERIES A PREFERRED
STOCK. Notwithstanding any other provisions of this Certificate of Designation
(other than the provisions set forth in paragraph (iii)(F)), Global Series A
Preferred Stock may not be transferred as a whole except by DTC to a nominee of
DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any
such nominee to a successor depository or a nominee of such successor
depository.

         (F) AUTHENTICATION OF CERTIFICATED SERIES A PREFERRED STOCK. If at any
time:

         (1) DTC notifies the Company that DTC is unwilling or unable to

     Preferred Stock) pursuant to Rule 144 under the Securities Act or an
     effective registration statement under the Securities Act:

              (I) in the case of any Transfer Restricted Security that is a

         (4) No service charge shall be made to a Holder for any registration of
     transfer or exchange upon surrender of any Series A Preferred Stock
     Certificate at the office of the Transfer Agent maintained for that
     purpose. However, the Company may require payment of a sum sufficient to

              Preferred Stock shall not be required to bear the legend set forth
              in paragraph (iii)(G) above but shall continue to be subject to
              the provisions of paragraph (iii)(D) hereof; PROVIDED, HOWEVER,
              that with respect to any request for an exchange of Series A
              Preferred Stock that is represented by Global Series A Preferred
              Stock for Certificated Series A Preferred Stock that does not bear
              the legend set forth in paragraph (iii)(G) above in connection
              with a sale or transfer thereof pursuant to Rule 144 (and based
              upon an opinion of counsel if the Company so requests), the Holder
              thereof shall certify in writing to the Transfer Agent that such
              request is being made pursuant to Rule 144 (such certification to

         (iv) REPLACEMENT CERTIFICATES. If a mutilated Series A Preferred Stock
certificate is surrendered to the Transfer Agent or if the Holder of a Series A
Preferred Stock certificate claims that the Series A Preferred Stock certificate
has been lost, destroyed or wrongfully taken, the Company shall issue and the
Transfer Agent shall countersign a replacement Series A Preferred Stock
certificate if the reasonable requirements of the Transfer Agent and of Section
8-405 of the Uniform Commercial Code as in effect in the State of New York are
met. If required by the Transfer Agent or the Company, such Holder shall furnish
an indemnity bond sufficient in the judgment of the Company and the Transfer
Agent to protect the Company and the Transfer Agent from any loss which either
of them may suffer if an Series A Preferred Stock certificate is replaced. The
Company and the Transfer Agent may charge the Holder for their expenses in
replacing a Series A Preferred Stock certificate. Every replacement Series A
Preferred Stock certificate is an additional obligation of the Company.

of Series A Preferred Stock) for each share of Series A Preferred Stock so
transferred.

                            ARTICLE 1 - STOCKHOLDERS


         1.1   PLACE OF MEETINGS. All meetings of stockholders shall be held at
such place within or without the State of Delaware as may be designated from
time to time by the Board of Directors or the President or, if not so
designated, at the registered office of the corporation.

         1.2   ANNUAL MEETING. The annual meeting of stockholders for the
election of directors and for the transaction of such other business as may
properly be brought before the meeting shall be held on a date to be fixed by
the Board of Directors or the President (which date shall not be a legal holiday
in the place where the meeting is to be held) at the time and place to be fixed
by the Board of Directors or the President and stated in the notice of the
meeting. If no annual meeting is held in accordance with the foregoing
provisions, the Board of Directors shall cause the meeting to be held as soon
thereafter as convenient. If no annual meeting is held in accordance with the
foregoing provisions, a special meeting may be held in lieu of the annual
meeting, and any action taken at that special meeting shall have the same effect
as if it had been taken at the annual meeting, and in such case all references
in these Bylaws to the annual meeting of the stockholders shall be deemed to
refer to such special meeting.

         1.3   SPECIAL MEETINGS. Special meetings of stockholders may be called
at any time by the President or by 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.

         1.4   NOTICE OF MEETINGS. Except as otherwise provided by law, written
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notices of all meetings
shall state the place, date and hour of the meeting. The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called. If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

         1.5   VOTING LIST. The officer who has charge of the stock ledger of
the corporation shall prepare, at least 10 days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
10 days prior to the meeting, at a place within the city where the meeting is to
be held. The list shall also be produced and kept at the time and place of the
meeting during the whole time of the meeting, and may be inspected by any
stockholder who is present.

         1.6   QUORUM. Except as otherwise provided by law, the Certificate of
Incorporation or these Bylaws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.

         1.7   ADJOURNMENTS. Any meeting of stockholders may be adjourned to any
other time and to any other place at which a meeting of stockholders may be held
under these Bylaws by the stockholders present or represented at the meeting and
entitled to vote, although less than a quorum, or, if no stockholder is present,
by any officer entitled



                                        3

<PAGE>   4
to preside at or to act as Secretary of such meeting. It shall not be necessary
to notify any stockholder of any adjournment of less than 30 days if the time
and place of the adjourned meeting are announced at the meeting at which
adjournment is taken, unless after the adjournment a new record date is fixed
for the adjourned meeting. At the adjourned meeting, the corporation may
transact any business which might have been transacted at the original meeting.

         1.8   VOTING AND PROXIES. Each stockholder shall have one vote for each
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation. Each stockholder of record entitled to vote
at a meeting of stockholders, or to express consent or dissent to corporate
action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by
written proxy executed by the stockholder or his authorized agent and delivered
to the Secretary of the corporation. No such proxy shall be voted or acted upon
after three years from the date of its execution, unless the proxy expressly
provides for a longer period.

         1.9   ACTION AT MEETING. When a quorum is present at any meeting, the
holders of shares of stock representing a majority of the votes cast on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of stock of
that class representing a majority of the votes cast on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these Bylaws. When a quorum is present at any meeting, any
election by stockholders shall be determined by a plurality of the votes cast on
the election.

         1.10  ACTION WITHOUT MEETING. Any action required or permitted to be
taken at any annual or special meeting of stockholders of the corporation may be
taken without a meeting, without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, is signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote on such action were present and voted. Prompt notice of the
taking of corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.


                              ARTICLE 2 - DIRECTORS

         2.1   GENERAL POWERS. The business and affairs of the corporation shall
be managed by or under the direction of a Board of Directors, who may exercise
all of the powers of the corporation except as otherwise provided by law or the
Certificate of Incorporation. In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

         2.2   NUMBER; ELECTION AND QUALIFICATION. The number of directors which
shall constitute the whole Board of Directors shall be determined by resolution
of the stockholders or the Board of Directors, but in no event shall be less
than one. The number of directors may be decreased at any time and from time to
time either by the stockholders or by a majority of 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.

         2.3   ENLARGEMENT OF THE BOARD. The number of directors may be
increased at any time and from time to time by the stockholders or by a majority
of the directors then in office.

         2.4   TENURE. Each director shall hold office until the next annual
meeting and until his successor is elected and qualified, or until his earlier
death, resignation or removal.

         2.5   VACANCIES. Unless and until filled by the stockholders, any
vacancy in the Board of Directors, however occurring, including a vacancy
resulting from an




                                        4

<PAGE>   5
enlargement of the Board, may be filled 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

         affiliate of the Company within the meaning of Rule 405, (ii) a holder
         who acquires Exchange Shares outside the ordinary course of such

         understandings with any person to participate in the Exchange Offer for
         the purpose of a distribution (within the meaning of the Securities
         Act) of the Exchange Shares and (iv) a holder that is a broker-dealer,
         but only with respect to Exchange Shares received by such broker-dealer
         pursuant to an Exchange Offer in exchange for Registrable Shares
         acquired by the broker-dealer directly from the Company.

                  "Rule 144", "Rule 405" and "Rule 415" shall mean, in each
         case, such rule promulgated under the Securities Act (or any successor

                  "Shelf Registration" shall have the meaning assigned thereto
         in Section 2(b) hereof.

         2. Registration Under the Securities Act.

         (a) Except as set forth in Section 2(b) below, the Company agrees to
file under the Securities Act, as soon as practicable, but no later than 90 days
after the Time of Delivery, a registration statement relating to an offer to
exchange (such registration statement, the "Exchange Registration Statement",
and such offer, the "Exchange Offer") any and all of the Shares for a like
number of shares of preferred stock issued by the Company, which shares are
substantially identical to the Shares (and are entitled to the benefits of a
certificate of designation which is substantially identical to the Certificate
of Designation or is the Certificate of Designation), except that they have been
registered pursuant to an effective registration statement under the Securities
Act and do not contain registration rights, transfer restrictions and provisions
for the additional dividends contemplated in Section 2(c) below (such new shares
of preferred stock hereinafter called "Exchange Shares"). The Company agrees to
use its best efforts to cause the Exchange Registration Statement to become
effective under the Securities Act as soon as practicable, but no later than
150 days after the Time of Delivery. The Exchange Offer will be registered under
the Securities Act on the appropriate form required by the Commission and will
comply with all applicable tender offer rules and regulations under the Exchange
Act and all applicable federal and state securities laws. The Company further
agrees to hold the Exchange Offer open for at least 30 days, use its best
efforts to commence and complete the Exchange Offer no later than 45 days after
such Registration Statement has become effective, and issue Exchange Shares for
all Registrable Shares that have been properly tendered and not withdrawn on or
prior to the expiration of the Exchange Offer. The Exchange Offer will be deemed
to have been "completed" only if the Exchange Shares received by holders other
than Restricted Holders in the Exchange Offer for Registrable Shares are, upon
receipt, transferable by each such holder without need for further compliance
with Section 5 of the Securities Act (except for the requirement to deliver a
prospectus included in the Exchange Registration Statement applicable to resales
by broker-dealers of Exchange Shares received by such broker-dealer pursuant to
an Exchange Offer in exchange for Registrable Shares other than those acquired
by the broker-dealer directly from the Company), and without material
restrictions under the blue sky or securities laws of a substantial majority of
the States of the United States of America. The Exchange Offer shall be deemed
to have been completed upon the earlier to occur of (i) the Company having
exchanged the Exchange Shares for all outstanding Registrable Shares pursuant to
the Exchange Offer and (ii) the Company having exchanged, pursuant to the
Exchange Offer, Exchange Shares for all Registrable Shares that have been
properly tendered and not withdrawn before the expiration of the Exchange Offer,
which shall be on a date that is at least 30 days following the commencement of
the Exchange Offer. The Company agrees (x) to include in the Exchange
Registration Statement a prospectus for use in connection with any resales of
Exchange Shares by a broker-dealer, other than resales of Exchange Shares
received by a broker-dealer pursuant to an Exchange Offer in exchange for
Registrable Shares acquired by the broker-dealer directly from the Company, and
(y) to keep such Exchange Registration Statement effective for a period (the
"Resale Period") beginning when Exchange Shares are first issued in the Exchange
Offer and ending upon the earlier of (x) the expiration of the 90th day after
the Exchange Offer has been completed or (y) such time as such broker-dealers no
longer own any Registrable Shares. With respect to such Exchange Registration
Statement, each broker-dealer that holds Exchange Shares received in an Exchange
Offer in exchange for Registerable Shares not acquired by it directly from the
Company shall have the benefit of the rights of indemnification and contribution
set forth in Sections 6(a), (c), (d) and (e) hereof.



                                       3
<PAGE>   4
         (b) If prior to the time the Exchange Offer is completed existing
Commission interpretations are changed such that the shares of preferred stock
received by holders other than Restricted Holders in the Exchange Offer for
Registrable Shares are not or would not be, upon receipt, transferable by each
such holder without need for further compliance with Section 5 of the Securities
Act (except for the requirement to deliver a prospectus included in the Exchange
Registration Statement applicable to resales by a broker-dealer of Exchange
Shares received by such broker-dealer pursuant to an Exchange Offer in exchange
for Registrable Shares other than those acquired by the broker-dealer directly
from the Company), in lieu of conducting the Exchange Offer contemplated by
Section 2(a), the Company shall use its best efforts to file under the
Securities Act a "shelf" registration statement providing for the registration
of, and the sale on a continuous or delayed basis by the holders of, all of the
Registrable Shares, pursuant to Rule 415 or any similar rule that may be adopted
by the Commission (such filing, the "Shelf Registration" and such registration
statement, the "Shelf Registration Statement"). In addition, in the event that
the Purchasers shall not have resold all of the Shares (other than Shares
purchased by an affiliate of any Purchaser for investment purposes) initially
purchased by them from the Company pursuant to the Purchase Agreement, prior to
the consummation of the Exchange Offer, the Company shall file under the
Securities Act as soon as practicable a Shelf Registration Statement, which if
permitted by the Commission may be done by way of a post-effective amendment to
the Exchange Registration Statement. The Company agrees to use its best efforts
to cause the Shelf Registration Statement to become or be declared effective no
later than 120 days after such Shelf Registration Statement is filed and to keep
such Shelf Registration Statement continuously effective for a period (the
"Effectiveness Period") ending on the earlier of (x) the second anniversary of
the Effective Time (or such later date as determined by adding the number of
days in all Information Delay Periods to the date of such second anniversary) or
(y) such time as there are no longer any Registrable Shares outstanding. The
Company further agrees to supplement or make amendments to the Shelf
Registration Statement, as and when required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or rules and regulations
promulgated thereunder for a shelf registration, and the Company agrees to
furnish to the holders of the Registrable Shares copies of any such supplement
or amendment to such registration statement prior to its being used or promptly
following its filing with the Commission. Attached as Exhibit A hereto is a form
of Notice of Registration Statement and Selling Securityholder Questionnaire to
be completed by holders in connection with a Shelf Registration pursuant to this
Section 2(b), which may be amended or supplemented to the extent reasonably
determined by counsel to the Company.

         (c) In the event that (i) the Company has not filed the Exchange
Registration Statement or Shelf Registration Statement on or before the date on
which such registration statement is required to be filed pursuant to Section
2(a) or 2(b), respectively, or (ii) such Exchange Registration Statement or
Shelf Registration Statement has not become effective or been declared effective
by the Commission on or before the date on which such registration statement is
required to become or be declared effective pursuant to Section 2(a) or 2(b),
respectively, or (iii) the Exchange Offer has not been completed within 180 days
after the Time of Delivery (if the Exchange Offer is then required to be made)
or (iv) any Exchange Registration Statement or Shelf Registration Statement
required by Section 2(a) or 2(b) hereof is filed and declared effective but
shall thereafter either be withdrawn by the Company or shall become subject to
an effective stop order issued pursuant to Section 8(d) of the Securities Act
suspending the effectiveness of such registration statement (except as
specifically permitted herein) without being succeeded immediately by an
additional registration statement filed and declared effective (each such event
referred to in clauses (i) through (iv), a "Registration Default" and each
period during which a Registration Default has occurred and is continuing, a
"Registration Default Period"), then, as liquidated damages for such
Registration Default, subject to the provisions of Section 9(b), special
dividends ("Special Dividends"), in addition to the Base Dividends, shall
accumulate at a per annum rate of 0.50% on the Specified Amount (as defined in
the Certificate of Designation) for the first 90 days of the Registration
Default Period, at a per annum rate of 0.75% on the Specified Amount for the
second 90 days of the Registration Default Period and at a per annum rate of
1.00% on the Specified Amount thereafter for the remaining portion of the
Registration Default Period. The Special Dividends shall be payable in cash
quarterly in arrears on each March 1, June 1, September 1 and December 1.
Special Dividends, if any, shall be computed on the basis of a 360 day year of
twelve 30-day months and the number of days actually elapsed.



                                       4

         (d) The Company shall use its reasonable best efforts to effect the
transactions contemplated herein as so contemplated.

         (e) Any reference herein to a registration statement as of any time
shall be deemed to include any document incorporated, or deemed to be
incorporated, therein by reference as of such time and any reference herein to
any post-effective amendment to a registration statement as of any time shall be
deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time.

         (f) Notwithstanding anything to the contrary in this Agreement,
including without limitation Section 2 and 3 hereof, if at any time prior to the
expiration of the Effectiveness Period, outside counsel to the Company (which
counsel shall be experienced in securities laws matters) has determined in good
faith that it is reasonable to conclude that the filing of the Shelf
Registration Statement or the compliance by the Company with its disclosure
obligations in connection with such registration statement may require the
disclosure of information which the Board of Directors of the Company has
identified as material and which the Board of Directors has determined that the
Company has a bona fide business purpose for preserving as confidential, then
the Company may delay the filing or the effectiveness of the Shelf Registration
Statement (if not then filed or effective, as applicable) and shall not be
required to maintain the effectiveness thereof or amend or supplement the
Exchange Registration Statement or the Shelf Registration Statement for a period
(an "Information Delay Period") expiring three business days after the earlier
to occur of (A) the date on which such material information is disclosed to the
public or ceases to be material or the Company is able to so comply with its
disclosure obligations and Commission requirements or (B) 45 days after the
Company notifies the Holders of such good faith determination. There shall not
be more than four Information Delay Periods during the Effectiveness Period, and
there shall not be two Information Delay Periods during any contiguous 135 day
period.

         (g) The Company will give prompt written notice, in such manner
prescribed by Section 9(c) hereof, to each holder of each Information Delay
Period. Such notice shall be given as soon as practicable after the Board of
Directors makes the determination referenced in Section 2(f). Such notice shall
state to the extent, if any, as is practicable, an estimate of the duration of
such Information Delay Period. Each holder, by his acceptance of any Registrable
Shares, agrees that (i) upon receipt of such notice of an Information Delay
Period it will forthwith discontinue disposition of Registrable Shares pursuant
to the Shelf Registration Statement, and (ii) will not deliver any prospectus
forming a part of the Shelf Registration Statement in connection with any sale
of Registrable Shares, as applicable until the expiration of such Information
Delay Period.

         (h) In the event the Company enters into an Information Delay Period,
the Company will have no liability for failing to perform any obligations it may
have pursuant to Section 2 and 3 of this Agreement during such delay period;
provided, however, that nothing in Sections 2(f) through (h) shall prevent the
provisions of Section 2(c) of this Agreement from being operative and if Special
Dividends are accruing at the commencement of an Information Delay Period or a
Registration Default occurs during an Information Delay Period, Special
Dividends shall continue to accumulate until the Registration Default giving
rise to the accumulation of Special Dividends shall have been cured.

         3. Registration Procedures.

         (a)   (i)   In connection with the Exchange Offer, the Company shall
comply with all of the provisions of Section 3(d) and Section 3(e) below, shall
use its best efforts to effect such exchange to permit the sale of Registrable
Shares being sold in accordance with the intended method or methods of
distribution thereof, and, prior to effectiveness of the Exchange Offer
Registration Statement, shall, if required by the Commission, provide a
supplemental letter to the Commission (A) stating that the Company is
registering the Exchange Offer in reliance on the position of the Commission
enunciated in EXXON CAPITAL HOLDINGS CORPORATION (available May 13, 1988),
MORGAN STANLEY AND CO., INC. (available June 5, 1991) and (B) including a
representation that the Company has not entered into any arrangement or
understanding with any person to distribute the Exchange Shares to be received
in the Exchange Offer and, if true, that, to the best of the Company's
information and belief, each holder participating in the Exchange Offer is
acquiring the Exchange Shares in its ordinary



                                       5
<PAGE>   6
course of business and has no arrangement or understanding with any person to
participate in the distribution of the Exchange Shares received in the Exchange
Offer.

               (ii)  As a condition to its participation in the Exchange Offer
pursuant to the terms of this Agreement, each holder of Registrable Shares shall
furnish, upon the request of the Company, prior to the consummation thereof, a
written representation to the Company (which may be contained in the letter of
transmittal contemplated by the Exchange Offer Registration Statement) to the
effect that (A) it is not an affiliate of the Company, (B) it is not engaged in,
and does not intend to engage in, and has no arrangement or understanding with
any person to participate in, a distribution of the Exchange Shares to be issued
in the Exchange Offer and (C) it is acquiring the Exchange Shares in its
ordinary course of business. In addition, all such holders of Registrable Shares
shall otherwise cooperate in the Company's preparations for the Exchange Offer.
Each holder hereby acknowledges and agrees that any broker-dealer and any such
holder, in either case, using the Exchange Offer (1) could not under Commission
policy as in effect on the date of this Agreement rely on the position of the
Commission enunciated in MORGAN STANLEY AND CO., INC. (available June 5, 1991)
and EXXON CAPITAL HOLDINGS CORPORATION (available May 13, 1988), as interpreted
in the Commission's letter to Shearman & Sterling dated July 2, 1993, and
similar no-action letters, and (2) must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction and that such a secondary resale transaction must
be covered by an effective registration statement containing the selling
shareholder information required by Item 507 or 508, as applicable, of
Regulation S-K if the resales are of Exchange Shares obtained by such holder in
exchange for Exchange Shares acquired by such holder directly from the Company
or an affiliate of the Company.

         If the Company files a registration statement pursuant to Section 2(a)
or Section 2(b), the following provisions shall apply:

         (b) In connection with the Company's obligations with respect to the
registration of Exchange Shares as contemplated by Section 2(a) (the "Exchange
Registration"), if applicable, the Company shall, as soon as reasonably possible
(or as otherwise specified):

                  (i) prepare and file with the Commission, as soon as
         practicable, but no later than 90 days after the Time of Delivery, an
         Exchange Registration Statement on any form which may be utilized by
         the Company and which shall permit the Exchange Offer and resales of
         Exchange Shares by broker-dealers during the Resale Period to be
         effected as contemplated by Section 2(a), and use its best efforts to
         cause such Exchange Registration Statement to become effective as soon
         as practicable thereafter, but no later than 150 days after the Time of
         Delivery;

                  (ii) as soon as practicable prepare and file with the
         Commission such amendments and supplements to such Exchange
         Registration Statement and the prospectus included therein as may be
         necessary to effect and maintain the effectiveness of such Exchange
         Registration Statement for the periods and purposes contemplated in
         Section 2(a) hereof and as may be required by the applicable rules and
         regulations of the Commission and the instructions applicable to the
         form of such Exchange Registration Statement, and promptly provide each
         broker-dealer holding Exchange Shares with such number of copies of the
         prospectus included therein (as then amended or supplemented), in
         conformity in all material respects with the requirements of the
         Securities Act and the rules and regulations of the Commission
         thereunder, as such broker-dealer reasonably may request prior to the
         expiration of the Resale Period, for use in connection with resales of
         Exchange Shares;

                  (iii) promptly notify the holders of Registrable Shares, the
         sales or placement agent, if any, and the managing underwriter or
         underwriters, if any and each broker-dealer that has requested copies
         of the prospectus included in such registration statement, and confirm
         such advice in writing, (A) when such Exchange Registration Statement
         or the prospectus included therein or any prospectus amendment or
         supplement or post-effective amendment has been filed, and, with
         respect to such Exchange Registration Statement or any post-effective
         amendment, when the same has become effective, (B) of any comments by
         the Commission and by the Blue Sky or securities commissioner or
         regulator of any state with respect thereto or any request by the
         Commission for amendments or



                                       6
<PAGE>   7
         supplements to such Exchange Registration Statement or prospectus or
         for additional information, (C) of the issuance by the Commission of
         any stop order suspending the effectiveness of such Exchange
         Registration Statement or the initiation or threatening of any
         proceedings for that purpose, (D) if at any time the representations
         and warranties of the Company contemplated by Section 5 hereof cease to
         be true and correct in all material respects, (E) of the receipt by the
         Company of any notification with respect to the suspension of the
         qualification of the Exchange Shares for sale in any jurisdiction or
         the initiation or threatening of any proceeding for such purpose or (F)
         at any time during the Resale Period when a prospectus is required to
         be delivered under the Securities Act, that such Exchange Registration
         Statement, prospectus, prospectus amendment or supplement or
         post-effective amendment thereto does not conform in all material
         respects to the applicable requirements of the Securities Act and the
         rules and regulations of the Commission thereunder or contains an
         untrue statement of a material fact or omits to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in light of the circumstances then existing;

                  (iv) in the event that the Company would be required to issue
         the notice required by Section 3(b)(iii)(F) above, prepare and furnish
         without delay to each such holder a reasonable number of copies of a
         prospectus supplemented or amended so that, as thereafter delivered to
         purchasers of such Exchange Shares during the Resale Period, such
         prospectus shall conform in all material respects to the applicable
         requirements of the Securities Act and the rules and regulations of the
         Commission thereunder and shall not contain an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading in
         light of the circumstances then existing; each holder of Registrable
         Shares agrees that upon receipt of any notice from the Company pursuant
         to Section 3(b)(iii)(C) or (F) hereof, such holder shall forthwith
         discontinue the disposition of Exchange Shares pursuant to the Exchange
         Registration Statement applicable to such Exchange Shares until such
         holder shall have received copies of such amended or supplemented
         prospectus, and if so directed by the Company, such holder shall
         deliver to the Company (at the Company's expense) all copies, other
         than permanent file copies, then in such holder's possession of the
         prospectus covering such Exchange Shares at the time of receipt of such
         notice;

                  (v) use its best efforts to obtain the withdrawal of any order
         suspending the effectiveness of such Exchange Registration Statement or
         any post-effective amendment thereto at the earliest practicable date;

                  (vi) use its best efforts to (A) register or qualify the
         Exchange Shares under the securities laws or blue sky laws of such
         jurisdictions as are contemplated by Section 2(a), to the extent
         required by such laws, no later than the commencement of the Exchange
         Offer, (B) keep such registrations or qualifications in effect and
         comply with such laws so as to permit the continuance of offers, sales
         and dealings therein in such jurisdictions until the expiration of the
         Resale Period and (C) take any and all other actions as may be
         reasonably necessary or advisable to enable each broker-dealer holding
         Exchange Shares to consummate the disposition thereof in such
         jurisdictions; provided, however, that the Company shall not be
         required for any such purpose to (1) qualify as a foreign corporation
         in any jurisdiction wherein it would not otherwise be required to
         qualify but for the requirements of this Section 3(b)(vi), (2) consent
         to general service of process in any such jurisdiction or (3) make any
         changes to its certificate of incorporation or by-laws or any agreement
         between it and its stockholders;

                  (vii) use its best efforts to obtain the consent or approval
         of each governmental agency or authority, whether federal, state or
         local, which may be required to effect the Exchange Registration, the
         Exchange Offer and the offering and sale of Exchange Shares by
         broker-dealers during the Resale Period;

                  (viii) provide a CUSIP number for all Exchange Shares, not
         later than the applicable Effective Time;

                  (ix) comply with all applicable rules and regulations of the
         Commission, and make generally available to its security holders as
         soon as practicable but no later than eighteen months after the
         effective date of such Exchange



                                       7

         Registration Statement, an earnings statement of the Company and any
         subsidiaries complying with Section 11(a) of the Securities Act
         (including, at the option of the Company, Rule 158 thereunder).

         (c) In connection with the Company's obligations with respect to the
Shelf Registration, if applicable, the Company shall use its best efforts to
cause the Shelf Registration to permit the disposition of the Registrable Shares
by the holders thereof in accordance with the intended method or methods of
disposition thereof provided for in the Shelf Registration Statement. In
connection therewith, the Company shall:

                  (i) prepare and file with the Commission, as soon as
         practicable, a Shelf Registration Statement on any form which may be
         utilized by the Company and which shall permit the disposition of the
         Registrable Shares in accordance with the intended method or methods
         thereof, as specified in writing by the holders of the Registrable
         Shares, and use its best efforts to cause such Shelf Registration
         Statement to become effective no later than 120 days after such shelf
         registration statement is filed;

         material respects, (E) of the receipt by the Company of any
         notification with respect to the suspension of the qualification of the
         Registrable Shares for sale in any jurisdiction or the initiation or
         threatening of any proceeding for such purpose, or (F) if at any time
         when a prospectus is required to be delivered under the Securities Act,

         prospectus included in such Shelf Registration Statement (including
         each preliminary prospectus and any summary prospectus), in conformity
         in all material respects with the applicable requirements of the

         agent, if any, therefor and underwriter, if any, thereof shall
         reasonably request, (B) keep such registrations or qualifications in
         effect and comply with such laws so as to permit the continuance of
         offers, sales and dealings therein in such jurisdictions during the

         preparation and delivery of certificates representing Registrable
         Shares to be sold, which certificates shall be printed, lithographed or
         engraved, or produced by any combination of such methods, and which
         shall not bear any restrictive legends; and, in the case of an
         underwritten offering, enable such Registrable Shares to be in such

         made pursuant to clause (A) above or those contained in Section 5(a)
         hereof and the compliance with or satisfaction of any agreements or
         conditions contained in the underwriting agreement or other agreement

         of which notices shall contain the text of the amendment or waiver
         proposed or effected, as the case may be;

                  (xvii) in the event that any broker-dealer registered under
         the Exchange Act shall underwrite any Registrable Shares or participate
         as a member of an underwriting syndicate or selling group or "assist in
         the distribution" (within the meaning of the Rules of Fair Practice and
         the By-Laws of the National Association of Securities Dealers, Inc.
         ("NASD") or any successor thereto, as amended from time to time)
         thereof, whether as a holder of such Registrable Shares or as an
         underwriter, a placement or sales agent or a broker or dealer in
         respect thereof, or otherwise, cooperate with such broker-dealer in
         complying with the requirements of such Rules and By-Laws, including by
         (A) if such Rules or By-Laws shall so require, cooperate in the
         engaging of a "qualified independent underwriter" (as defined in the
         schedules thereto (or any successor thereto)) to participate in the
         preparation of the Shelf Registration Statement relating to such
         Registrable Shares, to exercise usual standards of due diligence in
         respect thereto and, if any portion of the offering contemplated by
         such Shelf Registration Statement is an underwritten offering or is
         made through a placement or sales agent, to recommend the price of such
         Registrable Shares, (B) indemnifying any such qualified independent
         underwriter to the extent of the indemnification of underwriters
         provided in Section 6 hereof, and (C) providing such information to
         such broker-dealer as may be required in order for such broker-dealer
         to comply with the requirements of the Rules of Fair Practice of the

         earnings statement of the Company and any subsidiary complying with
         Section 11(a) of the Securities Act (including, at the option of the
         Company, Rule 158 thereunder).

         (d) In the event that the Company would be required, pursuant to
Section 3(c)(vi)(F) above, to notify the selling holders of Registrable Shares,
the placement or sales agent, if any, therefor and the managing underwriters, if
any, thereof, as applicable, the Company shall without delay prepare and furnish
to each such holder, to each placement or sales agent, if any, and to each such
underwriter, if any, a reasonable number of copies of a prospectus supplemented
or amended so that,



                                       12
<PAGE>   13
as thereafter delivered to purchasers of Registrable Shares, such prospectus
shall conform in all material respects to the applicable requirements of the
Securities Act and the rules and regulations of the Commission thereunder and
shall not contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing. Each holder
of Registrable Shares agrees that upon receipt of any notice from the Company
pursuant to Section 3(c)(vi)(C) or (F) hereof, such holder shall forthwith
discontinue the disposition of Registrable Shares pursuant to the Shelf
Registration Statement applicable to such Registrable Shares until such holder
shall have received copies of such amended or supplemented prospectus, and if so
directed by the Company, such holder shall deliver to the Company (at the
Company's expense) all copies, other than permanent file copies, then in such
holder's possession of the prospectus covering such Registrable Shares at the
time of receipt of such notice.

         (e) The Company may require each holder of Registrable Shares as to
which any Shelf Registration pursuant to Section 2(b) is being effected to
furnish to the Company such information regarding such holder and such holder's
intended method of distribution of such Registrable Shares as the Company may
from time to time reasonably request in writing, but only to the extent that
such information is required in order to comply with the Securities Act. Each
such holder agrees to notify the Company as promptly as practicable of any
inaccuracy or change in information previously furnished by such holder to the
Company or of the occurrence of any event in either case as a result of which
any prospectus relating to such Shelf Registration contains or would contain an
untrue statement of a material fact regarding such holder or such holder's
intended method of disposition of such Registrable Shares or omits to state any
material fact regarding such holder or such holder's intended method of
disposition of such Registrable Shares required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing, and promptly to furnish to the Company any
additional information required to correct and update any previously furnished
information or required so that such prospectus shall not contain, with respect
to such holder or the disposition of such Registrable Shares, an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing.

         4. Registration Expenses.

         The Company agrees to bear and to pay or cause to be paid promptly,
upon request, all expenses incident to the Company's performance of or

all Commission and any NASD registration, filing and review fees and expenses,
(b) all fees and expenses in connection with the qualification of the Shares for

Section 3(c)(x) hereof and determination of their eligibility for investment

of such Registrable Shares may designate, including any reasonable fees and
disbursements of counsel for the selling holders or underwriters in connection
with such qualification and determination, (c) all expenses relating to the

all other documents in connection with the offering, sale or delivery of Shares
to be disposed of (including certificates representing the Shares), (d)
messenger, telephone and delivery expenses relating to the offering, sale or
delivery of Shares and the preparation of documents referred to in clause (c)

persons, including special experts, retained by the Company in connection with
such registration and determination of their eligibility for investment under
the "blue-sky" laws of such jurisdictions as any managing underwriters or the
holders of such Registrable Shares may designate, including any reasonable fees
and disbursements of one counsel for the selling holders or underwriters in
connection with such "blue-sky" qualification and determination (collectively,
the "Registration Expenses"). To the extent that any Registration Expenses are
incurred, assumed or paid by any holder of Registrable Shares or any placement
or sales agent therefor or underwriter thereof, the Company shall reimburse such
person for the full amount of the Registration Expenses so incurred, assumed or
paid reasonably promptly after receipt of a request therefor. Notwithstanding
the foregoing, the holders of the Registrable Shares being registered shall pay
all agency fees and commissions and underwriting discounts and commissions
attributable to the sale of such Registrable Shares and the fees and
disbursements of any counsel or other advisors or experts retained by such
holders (severally or jointly).

         5. Representations and Warranties.

         The Company represents and warrants to, and agrees with, each Purchaser
and each of the holders from time to time of Registrable Shares that:

                  (a) Each registration statement covering Registrable Shares
         and each prospectus (including any preliminary or summary prospectus)
         contained therein or furnished pursuant to Section 3(b) or Section 3(c)
         hereof and any further amendments or supplements to any such
         registration statement or prospectus, when it becomes effective or is
         filed with the Commission, as the case may be, and, in the case of an
         underwritten offering of Registrable Shares, at the time of the closing
         under the underwriting agreement relating thereto, will conform in all
         material respects to the applicable requirements of the Securities Act
         and the rules and regulations of the Commission thereunder and will not
         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading; and at all times subsequent to the
         Effective Time when a prospectus would be required to be delivered
         under the Securities Act, other than from (i) such time as a notice has
         been given to holders of Registrable Shares pursuant to Section
         3(c)(vi)(F) or Section 3(b)(iii)(F) hereof until (ii) such time as the
         Company furnishes an amended or supplemented prospectus pursuant to
         Section 3(e) or Section 3(b)(iv) hereof, each such registration
         statement, and each prospectus (including any summary prospectus)
         contained therein or furnished pursuant to Section 3(b) or Section 3(c)
         hereof, as then amended or supplemented, will conform in all material
         respects to the applicable requirements of the Securities Act and the
         rules and regulations of the Commission thereunder and will not contain
         an untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in the light of the circumstances then existing;
         provided, however, that this representation and warranty shall not
         apply to any statements or omissions made in reliance upon and in
         conformity with information furnished in writing to the Company by or
         on behalf of a holder or holders of Registrable Shares expressly for
         use therein.

                  (b) Any documents incorporated by reference in any prospectus
         referred to in Section 5(a) hereof, when they become or became
         effective or are or were filed with the Commission, as the case may be,
         will conform or conformed in all material respects to the requirements
         of the Securities Act or the Exchange Act, as applicable, and none of
         such documents will contain or contained an untrue statement of a
         material fact or will omit or omitted to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading; provided, however, that this representation and warranty
         shall not apply to any statements or omissions made in reliance upon
         and in conformity with information furnished in writing to the Company
         by or on behalf of a holder or holders of Registrable Shares expressly
         for use therein.

                  (c) The compliance by the Company with all of the provisions
         of this Exchange and Registration Rights Agreement and the consummation
         of the transactions herein contemplated will not (i) result in any
         violation of the



                                       14
<PAGE>   15
         provisions of the certificate of incorporation, as amended, or the
         by-laws of the Company or its subsidiaries, (ii) conflict with or
         result in a breach of any of the terms or provisions of, or constitute
         a default under, any indenture, mortgage, deed of trust, loan agreement
         or other agreement or instrument to which the Company or its Subsidiary
         is a party or by which the Company or its Subsidiary is bound or to
         which any of the property or assets of the Company or its Subsidiary is
         subject, or (iii) result in the violation of any statute or any order,
         rule or regulation of any court or governmental agency or body having
         jurisdiction over the Company or its Subsidiary or any of their
         properties other than, in the case of clauses (ii) and (iii) above, for
         any breach, default or violation which would not have a material
         adverse affect on the condition (financial or other), business,
         prospects (as set forth or incorporated by reference in the prospectus
         included in the applicable registration statement), affairs,
         management, financial position, shareholders' equity or results of
         operations of the Company and its Subsidiary taken as a whole; and no
         consent, approval, authorization, order, registration or qualification
         of or with any such court or governmental agency or body is required
         for the consummation by the Company of the transactions contemplated by
         this Exchange and Registration Rights Agreement, except the
         registration under the Securities Act of the Shares and such consents,
         approvals, authorizations, registrations or qualifications as may be
         required under State securities or blue sky laws in connection with the
         offering and distribution of the Shares.

                  (d) This Exchange and Registration Rights Agreement has been
         duly authorized, executed and delivered by the Company.

         6. Indemnification.

         (a) Indemnification by the Company. The Company shall indemnify and
hold harmless each of the holders of Registrable Shares included in a
registration statement filed pursuant to Section 2(a) or 2(b) hereof, and each
person who participates as a placement or sales agent or as an underwriter in
any offering or sale of such Registrable Shares against any losses, claims,
damages or liabilities, joint or several, to which such holder, agent or
underwriter may become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in any registration statement under which such
Registrable Shares were registered under the Securities Act, or any preliminary,
final or summary prospectus contained therein or furnished by the Company to any
such holder, agent or underwriter, or any amendment or supplement thereto, 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 the Company shall, and it hereby agrees
to, reimburse such holder, such agent and such underwriter for any reasonable
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable to any such
person 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 or omission or alleged omission made in such registration statement,
or preliminary, final or summary prospectus, or amendment or supplement thereto,
in reliance upon and in conformity with written information furnished to the
Company by or on behalf of a holder or holders of Registrable Shares expressly
for use therein;

         (b) Indemnification by the Holders and any Agents and Underwriters. The
Company may require, as a condition to including any Registrable Shares in any
registration statement filed pursuant to Section 2(b) hereof and to entering
into any underwriting agreement with respect thereto, that the Company shall
have received an undertaking reasonably satisfactory to it from the holder of
such Registrable Shares and from each underwriter named in any such underwriting
agreement, severally and not jointly, to (i) indemnify and hold harmless the
Company, and in the case of a Shelf Registration Statement all other holders of
Registrable Shares, against any losses, claims, damages or liabilities to which
the Company or such other holders of Registrable Shares may become subject,
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in
such



                                       15
<PAGE>   16
registration statement, or any preliminary, final or summary prospectus
contained therein or furnished by the Company to any such holder, agent or
underwriter, or any amendment or supplement thereto, 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, 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 or on behalf of such holder or underwriter expressly for use therein,
and (ii) reimburse the Company for any legal or other expenses reasonably
incurred by the Company in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that no such
holder shall be required to undertake liability to any person under this Section
6(b) for any amounts in excess of the dollar amount of the proceeds to be
received by such holder from the sale of such holder's Registrable Shares
pursuant to such registration.

         (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
party under subsection (a) or (b) above of written notice of the commencement of
any action, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party pursuant to the indemnification provisions of
or contemplated by this Section 6, notify such indemnifying party in writing of
the commencement of such action; but the omission so to notify the indemnifying
party shall not relieve it from any liability hereunder to the extent it is not
materially prejudiced as a result thereof (but shall relieve it from liability
under Section 6(a) or 6(b), as the case may be, to the extent the indemnifying
party is materially prejudiced) and in any event shall not relieve it from any
liability which it may have to any indemnified party other than under the
indemnification provisions of or contemplated by Section 6(a) or 6(b) hereof. In
case any such action shall be brought against any indemnified party and it shall
notify an indemnifying party of the commencement thereof, and such indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified
party (who shall not, except with the consent (which consent shall not be
unreasonably withheld) 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, such indemnifying party shall
not be liable to such indemnified party for any legal expenses of other counsel
or any other expenses, in each case subsequently incurred by such indemnified
party, in connection with the defense thereof other than reasonable costs of
investigation. The indemnifying party shall not be required to indemnify any
indemnified party for any amount paid or payable by such indemnified party in
the settlement of any action, proceeding or investigation without the written
consent of the indemnifying party, which consent shall not be unreasonably
withheld. No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or claim
in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to or an admission
of fault, culpability or a failure to act by or on behalf of any indemnified
party. No indemnifying party shall be required to indemnify an indemnified party
for any amount paid or payable by such indemnified party in the settlement of
any action, proceeding or investigation without the written consent of such
indemnifying party, which consent shall not be unreasonably withheld.

         (d) Contribution. If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among



                                       16
<PAGE>   17
other things, whether the untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by such indemnifying party or by such indemnified party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The parties hereto agree that it
would not be just and equitable if contributions pursuant to this Section 6(d)
were determined by pro rata allocation (even if the holders or any agents or
underwriters or all of them were treated as one entity for such purpose) or by
any other method of allocation which does not take account of the equitable
considerations referred to in this Section 6(d). The amount paid or payable by
an indemnified party as a result of the losses, claims, damages, or liabilities
(or actions in respect thereof) referred to above shall be deemed to include any
legal or other fees or expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 6(d), no holder shall be required
to contribute any amount in excess of the amount by which the dollar amount of
the proceeds received by such holder from the sale of any Registrable Shares
(after deducting any fees, discounts and commissions applicable thereto) exceeds
the amount of any damages which such holder has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission, and no underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable Shares
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 Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The holders' and any underwriters' obligations in this
Section 6(d) to contribute shall be several in proportion to the principal
amount of Registrable Shares registered or underwritten, as the case may be, by
them and not joint.

         (e) The obligations of the Company under this Section 6 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each officer, director and partner of
each holder, agent and underwriter and each person, if any, who controls any
holder, agent or underwriter within the meaning of the Securities Act; and the
obligations of the holders and any agents or underwriters contemplated by this
Section 6 shall be in addition to any liability which the respective holder,
agent or underwriter may otherwise have and shall extend, upon the same terms
and conditions, to each officer and director of the Company (including any
person who, with his consent, is named in any registration statement as about to
become a director of the Company) and to each person, if any, who controls the
Company within the meaning of the Securities Act.

         7. Underwritten Offerings.

         (a) Selection of Underwriters. If any of the Registrable Shares covered
by the Shelf Registration are to be sold pursuant to an underwritten offering,
the managing underwriter or underwriters thereof shall be designated by the
holders of at least a majority in aggregate principal amount of the Registrable
Shares to be included in such offering, provided that such designated managing
underwriter or underwriters is or are reasonably acceptable to the Company.

         (b) Number of Underwritten Offerings. The Company shall not be
required, unless the Company's reasonable out-of-pocket expenses related thereto
are reimbursed at closing of such offering by the selling shareholders, to
facilitate more than two underwritten offerings requested by holders of
Registrable Shares pursuant to this Agreement. Holders of a majority of the
Registrable Shares to be included in any such underwritten offering may, at any
time prior to the filing of a final prospectus relating to such offering, revoke
their request for an underwritten offering by providing a written notice to the
Company revoking such request and, if such holders reimburse the Company for all
its reasonable out-of-pocket expenses incurred in connection with such proposed
underwritten offering such request shall not be deemed an underwritten offering
for purposes of the limitation in the first sentence of this Section 3(b);
provided, however, that, if such revocation was based on the Company's failure
to comply in any material respect with its obligations hereunder, such
reimbursement shall not be required.



                                       17
<PAGE>   18
         (c) Participation by Holders. Each holder of Registrable Shares hereby
agrees with each other such holder that no such holder may participate in any
underwritten offering hereunder unless such holder (i) agrees to sell such
holder's Registrable Shares on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

         8. Rule 144.

         The Company covenants to the holders of Registrable Shares that to the
extent it shall be required to do so under the Exchange Act, the Company shall
timely file the reports required to be filed by it under the Exchange Act or the
Securities Act (including the reports under Section 13 and 15(d) of the Exchange
Act referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission
under the Securities Act) and the rules and regulations adopted by the
Commission thereunder, all to the extent required from time to time to enable
such holder to sell Registrable Shares without registration under the Securities
Act within the limitations of the exemption provided by Rule 144 under the
Securities Act, as such Rule may be amended from time to time, or any similar or
successor rule or regulation hereafter adopted by the Commission. Upon the
request of any holder of Registrable Shares in connection with that holder's
sale pursuant to Rule 144, the Company shall deliver to such holder a written
statement as to whether, to the best of its knowledge, it has complied with such
requirements.

         9. Miscellaneous.

         (a) No Inconsistent Agreements. The Company represents, warrants,
covenants and agrees that it has not granted, and shall not grant (other than
with the written consent of the holders of at least a majority of the
outstanding Registrable Shares), registration rights with respect to Registrable
Shares or any other securities which would be inconsistent with the terms
contained in this Exchange and Registration Rights Agreement.

         (b) Specific Performance. The parties hereto acknowledge that there
would be no adequate remedy at law if any party fails to perform any of their
respective obligations hereunder and that each party may be irreparably harmed
by any such failure, and accordingly agree that each party, in addition to any
other remedy to which they may be entitled at law or in equity, shall be
entitled to compel specific performance of the respective obligations of any
other party under this Exchange and Registration Rights Agreement in accordance
with the terms and conditions of this Exchange and Registration Rights
Agreement, in any court of the United States or any State thereof having
jurisdiction.

         (c) Notices. All notices, requests, claims, demands, waivers and other
communications hereunder shall be in writing and shall be deemed to have been
duly given when delivered by hand, if delivered personally or by courier, or
three days after being deposited in the mail (registered or certified mail,
postage prepaid, return receipt requested) as follows: If to the Company, to it
at 234 Copeland Street, Quincy, MA 02169, Attention: Secretary, with a copy to
Hale and Dorr LLP, 60 State Street, Boston, MA 02109, Attention: Jeffrey N.
Carp, and if to a holder, to the address of such holder set forth in the
security register or other records of the Company, or to such other address as
the Company or any such holder may have furnished to the other in writing in
accordance herewith, except that notices of change of address shall be effective
only upon receipt.

         (d) Parties in Interest. All the terms and provisions of this Exchange
and Registration Rights Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the parties hereto and the holders from
time to time of the Registrable Shares and the respective successors and assigns
of the parties hereto and such holders. In the event that any transferee of any
holder of Registrable Shares shall acquire Registrable Shares, in any manner,
whether by gift, bequest, purchase, operation of law or otherwise, such
transferee shall, without any further writing or action of any kind, be deemed a
beneficiary hereof for all purposes and such Registrable Shares shall be held
subject to all of the terms of this Exchange and



                                       18
<PAGE>   19
Registration Rights Agreement, and by taking and holding such Registrable Shares
such transferee shall be entitled to receive the benefits of, and be
conclusively deemed to have agreed to be bound by all of the applicable terms
and provisions of this Exchange and Registration Rights Agreement. If the
Company shall so request, any such successor, assign or transferee shall agree
in writing to acquire and hold the Registrable Shares subject to all of the
applicable terms hereof.

         (e) Survival. The respective indemnities, agreements, representations,
warranties and each other provision set forth in this Exchange and Registration
Rights Agreement or made pursuant hereto shall remain in full force and effect
regardless of any investigation (or statement as to the results thereof) made by
or on behalf of the Purchasers or any holder of Registrable Shares, any
director, officer or partner of such holder, any agent or underwriter or any
director, officer or partner thereof, or any controlling person of any of the
foregoing, and shall survive delivery of and payment for the Registrable Shares
pursuant to the Purchase Agreement and the transfer and registration of
Registrable Shares by such holder and the consummation of an Exchange Offer.

         (f) LAW GOVERNING. THIS EXCHANGE AND REGISTRATION RIGHTS AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF
NEW YORK.

         (g) Headings. The descriptive headings of the several Sections and
paragraphs of this Exchange and Registration Rights Agreement are inserted for
convenience only, do not constitute a part of this Exchange and Registration
Rights Agreement and shall not affect in any way the meaning or interpretation
of this Exchange and Registration Rights Agreement.

         (h) Entire Agreement; Amendments. This Exchange and Registration Rights
Agreement and the other writings referred to herein (including the form of
Shares) or delivered pursuant hereto which form a part hereof contain the entire
understanding of the parties with respect to its subject matter. This Exchange
and Registration Rights Agreement supersedes all prior agreements and
understandings between the parties with respect to its subject matter. This
Exchange and Registration Rights Agreement may be amended and the observance of
any term of this Exchange and Registration Rights Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) only by a written instrument duly executed by the Company and the
holders of at least a majority of the Registrable Shares at the time
outstanding. Each holder of any Registrable Shares at the time or thereafter 
outstanding shall be bound by any amendment or waiver effected pursuant to this
Section 9(h), whether or not any notice, writing or marking indicating such
amendment or waiver appears on such Registrable Shares or is delivered to such
holder. Notwithstanding the foregoing, a waiver or consent to departure from
the provisions hereof that relates exclusively to the rights of holders whose
Registrable Shares are being tendered pursuant to the Exchange Offer and that
does not affect directly or indirectly the rights of other holders whose
Registrable Shares are not being tendered pursuant to such Exchange Offer may be
given by the holders of at least a majority of the outstanding Registrable
Shares being tendered or registered.

         (i) Inspection. For so long as this Exchange and Registration Rights
Agreement shall be in effect, this Exchange and Registration Rights Agreement
and a complete list of the names and addresses of all the holders of Registrable
Shares shall be made available for inspection and copying on any business day by
any holder of Registrable Shares for proper purposes only (which shall include
any purpose related to the rights of the holders of Registrable Shares under the
Shares and this Agreement) at the offices of the Company at the address thereof
set forth in Section 9(c) above.



                                       19

         (j) Counterparts. This agreement may be executed by the parties in
counterparts, each of which shall be deemed to be an original, but all such

                                     (Date)


                  Reference is hereby made to the Exchange and Registration
Rights Agreement (the "Exchange and Registration Rights Agreement"), between
Network Plus Corp. (the "Company") and the Purchasers named therein. Pursuant to
the Exchange and Registration Rights Agreement, the Company has filed with the
United States Securities and Exchange Commission (the "Commission") a
registration statement on Form [___] (the "Shelf Registration Statement") for
the registration and resale under Rule 415 of the Securities Act of 1933, as
amended (the "Securities Act"), of the Company's 13-1/2% Series A Cumulative
Preferred Stock due 2009 (the "Shares"). A copy of the Exchange and Registration
Rights Agreement is attached hereto. All capitalized terms not otherwise defined
herein shall have the meanings ascribed thereto in the Exchange and Registration
Rights Agreement.

                  Each beneficial owner of Registrable Shares (as defined below)
is entitled to have the Registrable Shares beneficially owned by it included in
the Shelf Registration Statement. In order to have Registrable Shares included
in the Shelf Registration Statement, this Notice of Registration Statement and

Shelf Registration Statement and (ii) may not use the Prospectus forming a part
thereof for resales of Registrable Shares.

                  Certain legal consequences arise from being named as a Selling
Stockholder in the Shelf Registration Statement and related Prospectus.
Accordingly, holders and beneficial owners of Registrable Shares are advised to
consult their own securities law counsel regarding the consequences of being
named or not being named as a Selling Stockholder in the Shelf Registration
Statement and related Prospectus.

                  The term "REGISTRABLE SHARES" is defined in the Exchange and
Registration Rights Agreement.

    information furnished in writing to the Company by a Purchaser through
    Goldman, Sachs & Co. expressly for use therein;

         (b)   neither the Company nor Network Plus, Inc., a Massachusetts

    statements included in the Offering Circular any material loss or
    interference with its business from fire, explosion, flood or other
    calamity, whether or not covered by insurance, or from any labor dispute or
    court or governmental action, order or decree, otherwise than as set forth
    or contemplated in the Offering Circular; and, since the respective dates as
    of which information is given in the Offering Circular, other than option
    grants in the ordinary course of business, there has not been any change in
    the capital stock or long-term debt of the Company or its Subsidiary or any
    material adverse change, or any development involving a prospective material
    adverse change, in or affecting the general affairs, management, financial
    position, stockholders' equity or results of operations of the Company and
    its Subsidiary, otherwise than as set forth or contemplated in the Offering
    Circular;

         (c)   the Company and its Subsidiary do not own any real property and
    have good and marketable title to or the right to use all personal property
    owned or used by them, in each case free and clear of all liens,
    encumbrances and defects except such as are described in the Offering
    Circular or such as do not materially affect the value of such property and
    do not materially interfere with the use made and proposed to be made of
    such property by the Company or the Subsidiary; and any real property and
    buildings held under lease by the Company and its Subsidiary are held by
    them under valid, subsisting and enforceable leases with such exceptions as
    do not materially affect the value of such property and do not materially
    interfere with the use made and proposed to be made of such property and
    buildings by the Company and its Subsidiary;

         (d)   the Company has been duly incorporated and is validly existing as
    a corporation in good standing under the laws of Delaware, with power and
    authority (corporate and other) to own its properties and conduct its
    business as described in the Offering Circular, and has been duly qualified
    as a foreign corporation for the transaction of business and is in good
    standing under the laws of each other jurisdiction in which it owns or
    leases properties or conducts any business so as to require such
    qualification, or is subject to no material liability or disability by
    reason of the failure to be so qualified in any such jurisdiction; the
    Subsidiary is an entity validly constituted and validly existing under the
    laws of Massachusetts, with power and authority (corporate and other) to
    own, lease and operate its property and assets and to conduct its business
    as described in the Offering Circular, and has been duly qualified as a
    foreign corporation for the transaction of business and is in good standing
    under the laws of each other jurisdiction in which it owns or leases
    properties or conducts any business so as to require such qualification, or

    its Subsidiary, would individually or in the aggregate have a material 
    adverse effect on the financial position, stockholders' equity or results of

    in a U.S. automated inter-dealer quotation system, and the Company has been 
    advised that the Securities and the Warrants have been designated 
    PORTAL-eligible securities;

    Company Act");

         (u)   neither the Company, nor any affiliate of the Company, nor any

    (as defined in Rule 902 under the Securities Act), by means of any directed 
    selling efforts within the meaning of Rule 902 under the Securities Act and

    person any Securities or Warrants, or any securities of the same or a 
    similar class as the Securities or the Warrants, other than Securities 
    offered or sold to the Purchasers hereunder. The

    or sale, direct or indirect, in the United States or to any U.S. person (as 
    defined in Rule 902 under the Securities Act) of any Securities or Warrants 
    or any substantially similar security issued by the Company, within six 
    months subsequent to the date on which the distribution of the Securities 
    and the Warrants has been completed (as notified to the Company by Goldman, 
    Sachs & Co.), is made under restrictions and other circumstances reasonably 
    designed not to affect the status of the offer and sale of the Securities or
    the Warrants in the United States and to U.S. persons contemplated by this 
    Agreement as transactions exempt from the registration provisions of the 
    Securities Act;

         (w)   neither the Company nor any of its affiliates does business with
    the government of Cuba or with any person or affiliate located in Cuba

    statements of the Company, are independent public accountants with respect 
    to the Company under Rule 101 of the American Institute of Certified Public
    Accountants' Code of Professional Conduct, and its interpretations and 
    rulings; and

         (y)   the audited balance sheet of the Company as at December 31, 1997
    (including the notes thereto) included in the Offering Circular presents 
    fairly in all material respects the consolidated financial position of the 
    Company as at the date indicated and has been prepared in accordance with 
    generally accepted accounting principles ("GAAP"); the unaudited interim 
    financial statements of the Company (including the notes thereto) included 
    in the Offering Circular present fairly in all material respects the 
    financial position of the Company as at the dates indicated and the results 
    of operations and the changes in its financial position for the periods 
    specified, subject to year-end adjustments and have been prepared in 
    accordance with GAAP, except for the absence of footnotes and year-end 
    adjustments.

    comply with such laws so as to permit the continuance of sales and dealings
    therein in such jurisdictions for as long as may be necessary to complete

    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

    expiration of nine months after the date of the Offering Circular, any event
    shall have occurred as a result of which the Offering Circular as then
    amended or supplemented would include an untrue statement of a material fact
    or omit to state any material fact necessary in order to make the statements
    therein, in the light of the circumstances under which they were made when
    such Offering Circular is delivered, not misleading, or, if for any other

    Securities or Warrants or any substantially similar security issued by the
    Company

     additional information concerning the business and financial condition of
     the Company as you may from time to time reasonably request (such financial
     statements to be on a consolidated basis to the extent that the accounts of
     the Company and its subsidiaries are consolidated in reports furnished to
     its stockholders generally or to the Commission);

           (j)  during the period of two years after the Time of Delivery, the
     Company will not, and will not permit any of its "affiliates" (as defined
     in Rule 144 under the Securities Act) to, resell any of the Securities or
     the Warrants which constitute "restricted securities" under Rule 144 that
     have been reacquired by any of them except pursuant to an effective
     registration statement under the Securities Act;

           (k)  the Company shall file and use its best efforts to cause to be
     declared or become effective under the Securities Act, on or prior to 150
     days after the Time of Delivery, a registration statement on Form S-4
     providing for the registration of (i) another series of Preferred Stock of
     the Company, with terms identical to the Securities (the "Exchange
     Securities"), and (ii) the exchange of the Securities for the Exchange
     Securities, all in a manner that will permit persons who acquire the
     Exchange Securities to resell the Exchange Securities pursuant to Section
     4(1) of the Securities Act;

           (l)  to use the net proceeds received by it from the sale of the
     Securities pursuant to this Agreement in the manner specified in the
     Offering Circular under the caption "Use of Proceeds";

           (m)  to reserve and keep available at all times, free of preemptive
     rights, shares of Preferred Stock for the purpose of enabling the Company
     to satisfy any



                                        8


<PAGE>   9
     obligation or election to issue shares of Preferred Stock as dividends upon
     the Preferred Stock;

           (n)  to reserve and keep available at all times, free of preemptive
     rights, shares of Common Stock for the purpose of enabling the Company to
     satisfy any obligations to issue shares of its Common Stock upon exercise
     of the Warrants; and

           (o)  not to (and to cause any subsidiaries not to) take, directly or
     indirectly, any action which is designed to or which constitutes or which
     might reasonably be expected to cause or result in stabilization or
     manipulation of the price of any security of the Company.

     6.    The Company covenants and agrees with the several Purchasers that the
Company will pay or cause to be paid the following: (i) the fees, disbursements
and expenses of the Company's counsel and accountants in connection with the
issue of the Securities, the Warrants and the shares of Common Stock issuable
upon exercise of the Warrants and all other expenses in connection with the
preparation, printing and filing of the Preliminary Offering Circular and the
Offering Circular (which Offering Circular shall only be required to be
photocopied) and any amendments and supplements thereto and the mailing and
delivering of copies thereof to the Purchasers and dealers; (ii) the cost of
photocopying or producing any Agreement among Purchasers, this Agreement, the
Certificate of Designation, the Warrant Agreement, the Registration Rights
Agreement, the Blue Sky and Legal Investment Memoranda, closing documents
(including any compilations thereof) and any other documents in connection with
the offering, purchase, sale and delivery of the Securities; (iii) all expenses
in connection with the qualification of the Securities, the Warrants and the
shares of Common Stock issuable upon exercise of the Warrants for offering and
sale under state securities laws as provided in Section 5(b) hereof, including
the fees and disbursements of counsel for the Purchasers in connection with such
qualification and in connection with the Blue Sky and legal investment surveys;
(iv) any fees charged by securities rating services for rating the Securities;
(v) the cost of preparing the Securities and the Warrants; (vi) the fees and
expenses of the Transfer Agent, the Warrant Agent and any agent of the Transfer

in connection with the designation of the Securities, the Warrants and the
Common Stock for trading in PORTAL; and (viii) all other costs and expenses
incident to the performance of its obligations hereunder which are not otherwise
specifically provided for in this Section. It is understood, however, that,
except as provided in this Section, and Sections 8 and 11 hereof, the Purchasers
will pay all their own costs and expenses, including the fees of their counsel,
transfer taxes on resale of any of the Securities and the Warrants by them, and
any advertising expenses connected with any offers they may make.

     7.    The obligations of the Purchasers hereunder shall be subject, in
their discretion, to the condition that all representations and warranties and
other statements of the Company herein are, at and as of the Time of Delivery,
true and correct, the condition that the Company shall have performed all of its
obligations hereunder theretofore to be performed, and the following additional
conditions:

     (a)   Cravath, Swaine & Moore, counsel for the Purchasers, shall have
     furnished to you such opinion or opinions, dated the Time of Delivery, as
     to such matters as you may reasonably request, and such counsel shall have
     received such papers and information as they may reasonably request to
     enable them to pass upon such matters;

     (b)   Hale and Dorr LLP, counsel for the Company, shall have furnished to
     you their written opinion, dated the Time of Delivery, in form and
     substance satisfactory to you, with respect to the matters set forth in
     Schedule 7(b).

     (c)   Swidler Berlin Shereff Friedman, LLP, counsel for the Company, shall
     have furnished to you their written opinion, dated the Time of Delivery, in
     form and substance satisfactory to you, with respect to the matters set
     forth in Schedule 7(c).

     (d)   On the date of the Offering Circular prior to the execution of this
     Agreement and also at the Time of Delivery, PricewaterhouseCoopers LLP
     shall have furnished



                                        9

<PAGE>   10
     to you a letter or letters, dated the respective dates of delivery thereof,
     in form and substance satisfactory to you, to the effect set forth in Annex
     II hereto;

     (e)   neither the Company nor its Subsidiary shall have sustained since the
     date of the latest audited financial statements included in the Offering
     Circular any loss or interference with its business from fire, explosion,
     flood or other calamity, whether or not covered by insurance, or from any
     labor dispute or court or governmental action, order or decree, otherwise
     than as set forth or contemplated in the Offering Circular, and (ii) since
     the respective dates as of which information is given in the Offering
     Circular there shall not have been any change in the capital stock or
     long-term debt of the Company or its Subsidiary or any change, or any
     development involving a prospective change, in or affecting the general
     affairs, management, financial position, stockholders' equity or results of
     operations of the Company and its Subsidiary, otherwise than as set forth
     or contemplated in the Offering Circular, the effect of which, in any such
     case described in Clause (i) or (ii), is in the judgment of the
     Representatives so material and adverse as to make it impracticable or
     inadvisable to proceed with the public offering or the delivery of the
     Securities and the Warrants on the terms and in the manner contemplated in
     this Agreement and in the Offering Circular;

     (f)   on or after the date hereof (i) no downgrading shall have occurred in
     any rating accorded the Company's debt securities or preferred stock by any
     "nationally recognized statistical rating organization", as that term is
     defined by the Commission for purposes of Rule 436(g)(2) under the
     Securities Act, and (ii) no such organization shall have publicly announced
     that it has under surveillance or review, with possible negative
     implications, its rating of any of the Company's debt securities or
     preferred stock;

     (g)   on or after the date hereof there shall not have occurred any of the
     following: (i) a suspension or material limitation in trading in securities
     generally on the New York Stock Exchange; (ii) a general moratorium on
     commercial banking activities declared by either Federal or New York State
     authorities; (iii) the outbreak or escalation of hostilities involving the
     United States or the declaration by the United States of a national
     emergency or war, if the effect of any such event specified in this Clause
     (iii) in the judgment of the Representatives makes it impracticable or
     inadvisable to proceed with the delivery of the Securities and the Warrants
     on the terms and in the manner contemplated in the Offering Circular; or
     (iv) the occurrence of any material adverse change in the existing,
     financial, political or economic conditions in the United States or
     elsewhere which, in the judgment of the Representatives, would materially
     and adversely affect the financial markets or the markets for the
     Securities and other debt or preferred equity securities;

     (h)   the Securities, the Warrants and the Common Stock shall have been
     designated for trading on PORTAL;

     (i)   the Registration Rights Agreement shall have been duly authorized,
     executed and delivered by the Company;

     (j)   the Warrant Agreement shall have been duly authorized, executed and
     delivered by the Company;

     (k)   the Company shall have filed with the Secretary of State of the State
     of Delaware the Certificate of Designation;

     (l)   the Commitment Letter dated August 14, 1998, between the Company and
     Goldman Sachs Credit Partners, L.P. shall be in full force and effect; and

     (m)   the Company shall have furnished or caused to be furnished to you at
     the Time of Delivery certificates of officers of the Company satisfactory
     to you as to the accuracy of the representations and warranties of the
     Company herein at and as of such Time of Delivery, as to the performance by
     the Company of all of its obligations hereunder to be performed at or prior
     to such Time of Delivery, as to the matters set forth in subsection (e) of
     this Section and as to such other matters as you may reasonably request.

     8.    (a)  The Company will indemnify and hold harmless each Purchaser
against any losses, claims, damages or liabilities, joint or several, to which
such Purchaser may



                                       10

<PAGE>   11
become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or alleged untrue statement of a material
fact contained in the Preliminary Offering Circular, the Offering Circular, or
any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact necessary to make
the statements therein not misleading, and will reimburse each Purchaser for any
legal or other expenses reasonably incurred by such Purchaser in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall 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 or omission or
alleged omission made in the Preliminary Offering Circular or the Offering
Circular or any such amendment or supplement in reliance upon and in conformity
with written information furnished to the Company by any Purchaser through
Goldman, Sachs & Co. expressly for use therein.

     (b)   Each Purchaser will indemnify and hold harmless the Company against
any losses, claims, damages or liabilities to which the Company may become
subject, under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in the Preliminary Offering Circular or the Offering Circular, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact 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 the Preliminary Offering Circular or the Offering
Circular or any such amendment or supplement in reliance upon and in conformity
with written information furnished to the Company by such Purchaser through
Goldman, Sachs & Co. expressly for use therein; and will reimburse the Company
for any legal or other expenses reasonably incurred by the Company in connection
with investigating or defending any such action or claim as such expenses are
incurred.

     (c)   Promptly after receipt by an indemnified party under subsection (a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability hereunder to the extent it is not materially
prejudiced as a result thereof (but shall relieve it from liability under
Section 8(a) or 8(b), as the case may be, to the extent the indemnifying party
is materially prejudiced) and in any event shall not relieve it from any
liability which it may have to any indemnified party otherwise than under such
subsection. In case any such action shall be brought against any indemnified
party and it shall notify the indemnifying party of the commencement thereof,
the indemnifying party shall be entitled to participate therein and, to the
extent that it shall 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 shall not be liable to such indemnified
party under such subsection for any legal expenses of other counsel or any other
expenses, in each case subsequently incurred by such indemnified party, in
connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or claim
in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to, or an
admission of, fault, culpability or a failure to act, by or on behalf of any
indemnified party. No indemnifying party shall be required to indemnify an
indemnified party for any amount paid or payable by such indemnified party in
the settlement of any action, proceeding or investigation without the written
consent of such indemnifying party, which consent shall not be unreasonably
withheld.

     (d)   If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above



                                       11

<PAGE>   12
in respect of any losses, claims, damages or liabilities (or actions in respect
thereof) referred to therein, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Purchasers on the other from the offering of the
Securities and the Warrants. If, however, the allocation provided by the
immediately preceding sentence is not permitted by applicable law or if the
indemnified party failed to give the notice required under subsection (c) above,
then each indemnifying party shall contribute to such amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Company on the one
hand and the Purchasers on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Purchasers 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 Purchasers, in each case as set forth in the Offering Circular. 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
on the one hand or the Purchasers on the other and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Purchasers agree that it would not be
just and equitable if contribution pursuant to this subsection (d) were
determined by pro rata allocation (even if the Purchasers were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (d). The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in 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 such action or claim. Notwithstanding the
provisions of this subsection (d), no Purchaser shall be required to contribute
any amount in excess of the amount by which the total price at which the
Securities and the Warrants underwritten by it and distributed to investors were
offered to investors exceeds the amount of any damages which such Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. The Purchasers' 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 8 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
Purchaser within the meaning of the Securities Act; and the obligations of the
Purchasers under this Section 8 shall be in addition to any liability which the
respective Purchasers may otherwise have and shall extend, upon the same terms
and conditions, to each officer and director of the Company and to each person,
if any, who controls the Company within the meaning of the Securities Act.

     9.    (a)  If any Purchaser shall default in its obligation to purchase the
Securities and Warrants which it has agreed to purchase hereunder, you may in
your discretion arrange for you or another party or other parties to purchase
such Securities and Warrants on the terms contained herein. If within thirty-six
hours after such default by any Purchaser you do not arrange for the purchase of
such Securities and Warrants, then the Company shall be entitled to a further
period of thirty-six hours within which to procure another party or other
parties satisfactory to you to purchase such Securities and Warrants on such
terms. In the event that, within the respective prescribed periods, you notify
the Company that you have so arranged for the purchase of such Securities and
Warrants, or the Company notifies you that it has so arranged for the purchase
of such Securities and Warrants, you or the Company shall have the right to
postpone the Time of Delivery for a period of not more than seven days, in order
to effect whatever changes may thereby be made necessary in the Offering
Circular, or in any other documents or arrangements, and the Company agrees to
prepare promptly any amendments to the Offering Circular which in your opinion
may thereby be made necessary. The term "Purchaser" as used in this Agreement
shall include any person substituted under this Section with like effect as if
such



                                       12

<PAGE>   13
person had originally been a party to this Agreement with respect to such
Securities and Warrants.

     (b)   If, after giving effect to any arrangements for the purchase of the
Securities and Warrants of a defaulting Purchaser or Purchasers by you and the
Company as provided in subsection (a) above, the aggregate liquidation
preference of such Securities and such aggregate number of Warrants which
remains unpurchased does not exceed one-eleventh of the aggregate liquidation
preference of all the Securities and the aggregate number of Warrants, then the
Company shall have the right to require each non-defaulting Purchaser to
purchase the number of Securities and the aggregate number of Warrants which
such Purchaser agreed to purchase hereunder and, in addition, to require each
non-defaulting Purchaser to purchase its pro rata share (based on the number of
Securities and the aggregate number of Warrants which such Purchaser agreed to
purchase hereunder) of the Securities and Warrants of such defaulting Purchaser
or Purchasers for which such arrangements have not been made; but nothing herein
shall relieve a defaulting Purchaser from liability for its default.

     (c)   If, after giving effect to any arrangements for the purchase of the
Securities and Warrants of a defaulting Purchaser or Purchasers by you and the
Company as provided in subsection (a) above, the aggregate liquidation
preference of Securities which remains unpurchased exceeds one-eleventh of the
aggregate liquidation preference of all the Securities, or if the Company shall
not exercise the right described in subsection (b) above to require
non-defaulting Purchasers to purchase Securities and Warrants of a defaulting
Purchaser or Purchasers, then this Agreement shall thereupon terminate, without
liability on the part of any non-defaulting Purchaser or the Company, except for
the expenses to be borne by the Company and the Purchasers as provided in
Section 6 hereof and the indemnity and contribution agreements in Section 8
hereof; but nothing herein shall relieve a defaulting Purchaser from liability
for its default.

     10.   The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Purchasers, as set forth in
this Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Purchaser or any controlling person of any Purchaser, or the Company, or
any officer or director or controlling person of the Company, and shall survive
delivery of and payment for the Securities and Warrants.

     11.   If this Agreement shall be terminated pursuant to Section 9 hereof,
the Company shall not then be under any liability to any Purchaser except as
provided in Sections 6 and 8 hereof (as set forth in Section 9(c) hereof); but,
if for any other reason, the Securities and Warrants are not delivered by or on
behalf of the Company as provided herein, the Company will reimburse the
Purchasers through you for all out-of-pocket expenses approved in writing by
you, including fees and disbursements of counsel, reasonably incurred by the
Purchasers in making preparations for the purchase, sale and delivery of the
Securities and Warrants, but the Company shall then be under no further
liability to any Purchaser except as provided in Sections 6 and 8 hereof.

     12.   In all dealings hereunder, you shall act on behalf of each of the
Purchasers, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Purchaser made or given
by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Purchasers shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 32 Old Slip, 9th Floor, New York, New York 10004, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the Offering
Circular, Attention: Secretary; provided, however, that any notice to a
Purchaser pursuant to Section 8(c) hereof shall be delivered or sent by mail,
telex or facsimile transmission to such Purchaser at its address set forth in
its Purchasers' Questionnaire, or telex constituting such Questionnaire, which
address will be supplied to the Company by you upon request. Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.



                                       13

     13.   This Agreement shall be binding upon, and inure solely to the benefit
of, the Purchasers, the Company and, to the extent provided in Sections 8 and 10
hereof, the officers and directors of the Company and each person who controls
the Company or any Purchaser, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. No purchaser of any of the
Securities and Warrants from any Purchaser shall be deemed a successor or assign
by reason merely of such purchase.

     14.   Time shall be of the essence of this Agreement.

     15.   This Agreement shall be governed by and construed in accordance with
the laws of the State of New York.

     16.   This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such respective counterparts shall together constitute one and
the same instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us counterparts hereof (one for the Company and each of the
Representatives plus one for each counsel), and upon the acceptance hereof by
you, on behalf of each of the Purchasers, this letter and such acceptance hereof
shall constitute a binding agreement between each of the Purchasers and the
Company. It is understood that your acceptance of this letter on behalf of each
of the Purchasers is pursuant to the authority set forth in a form of Agreement
among Purchasers, the form of which shall be submitted to the Company for
examination upon request, but without warranty on your part as to the authority
of the signers thereof.

                                                   Very truly yours,

             Pursuant to Section 7(d) of the Purchase Agreement, the
accountants shall furnish letters to the Purchasers to the effect that:

             (i)   They are independent certified public accountants with
         respect to Network Plus, Inc. (the "Company") under rule 101 of the
         American Institute of Certified Public Accountants' Code of
         Professional Conduct, and its interpretations and rulings;

             (ii)  The unaudited selected financial information with respect to
         the results of operations and financial position of the Company for the
         three most recent fiscal years included in the Offering Circular agrees
         with the corresponding amounts (after restatements where applicable) in
         the audited financial statements for such three fiscal years;

             (iii) On the basis of limited procedures not constituting an audit
         in accordance with generally accepted auditing standards, consisting of
         a reading of the unaudited financial statements and other information
         referred to below, a reading of the latest available interim financial
         statements of the Company, inspection of the minute books of the
         Company since the date of the latest audited financial statements
         included in the Offering Circular, inquiries of officials of the
         Company responsible for financial and accounting matters and such other
         inquiries and procedures as may be specified in such letter, nothing
         came to their attention that caused them to believe that:

                   (A) the unaudited statements of operations and retained
             earnings, balance sheets and statements of cash flows included in
             the Offering Circular are not in conformity with generally accepted
             accounting principles applied on the basis substantially consistent
             with the basis for the unaudited condensed statements of operations
             and retained earnings, balance sheets and statements of cash flows
             included in the Offering Circular;

                   (B) any other unaudited income statement data and balance
             sheet items included in the Offering Circular do not agree with the
             corresponding items in the unaudited financial statements from
             which such data and items were derived, and any such unaudited data
             and items were not determined on a basis substantially consistent
             with the basis for the corresponding amounts in the audited
             financial statements included in the Offering Circular;

                   (C) the unaudited financial statements which were not
             included in the Offering Circular but from which were derived any
             unaudited condensed financial statements referred to in Clause (A)
             and any unaudited income statement data and balance sheet items
             included in the Offering Circular and referred to in Clause (B)
             were not determined on a basis substantially consistent with the
             basis for the audited financial statements included in the Offering
             Circular;

                   (D) any unaudited pro forma condensed financial statements
             included in the Offering Circular do not comply as to form in all
             material respects with the applicable accounting requirements or
             the pro forma adjustments have not been properly applied to the
             historical amounts in the compilation of those statements;

                   (E) as of a specified date not more than five days prior to
             the date of such letter, there have been any changes in the capital
             stock (other than issuances of capital stock upon exercise of
             options and stock appreciation rights, upon earn-outs of
             performance shares and upon conversions of convertible securities,
             in each case which were outstanding on the date of the latest
             financial statements included in the Offering Circular) or any
             increase in the long-term debt of the Company, or any decreases in
             consolidated net current assets or stockholders' equity or other
             items specified by the Representatives, or any increases in any
             items specified by the Representatives, in each case as compared
             with amounts shown in the latest balance sheet included in the
             Offering Circular except in each case for changes, increases or
             decreases which the Offering Circular discloses have occurred or
             may occur or which are described in such letter; and


<PAGE>   18
                   (F) for the period from the date of the latest financial
             statements included in the Offering Circular to the specified date
             referred to in Clause (E) there were any decreases in net revenues
             or operating profit or the total or per share amounts of net income
             or other items specified by the Representatives, or any increases
             in any items specified by the Representatives, in each case as
             compared with the comparable period of the preceding year and with
             any other period of corresponding length specified by the
             Representatives, except in each case for decreases or increases
             which the Offering Circular discloses have occurred or may occur or
             which are described in such letter; and

             (iv) In addition to the examination referred to in their report(s)
         included in the Offering Circular and the limited procedures,
         inspection of minute books, inquiries and other procedures referred to
         in paragraphs (iii) and (iv) above, they have carried out certain
         specified procedures, not constituting an audit in accordance with
         generally accepted auditing standards, with respect to certain amounts,
         percentages and financial information specified by the Representatives,
         which are derived from the general accounting records of the Company,
         which appear in the Offering Circular, and have compared certain of
         such amounts, percentages and financial information with the accounting
         records of the Company and have found them to be in agreement.

Dear Pricewaterhouse Coopers LLP:

     Goldman, Sachs & Co., as representatives of the Purchasers of the preferred
stock and warrants to be issued by Network Plus Corp. (the "Company"), will be
reviewing certain information relating to the Company that will be included in
the Offering Circular. This review process, applied to the information relation
to the issue, is substantially consistent with the due diligence review process
that we would perform if this placement of securities were being registered
pursuant to the Securities Act of 1933 (the "Securities Act"). It is recognized
however that what is "substantially consistent" may vary from situation to
situation and may not be the same as that done in a registered offering of the
same securities for the same issuer and whether the procedures being, or to be,
followed will be "substantially consistent" will be determined by us on a
case-by-case basis. We are knowledgeable with respect to the due diligence
review process that would be performed if this placement of securities were
being registered pursuant to the Securities Act. We hereby request that you
deliver to us a "comfort" letter concerning the financial statements of the
issuer and certain statistical and other data included in the offering document.
We will contact you to identify the procedures we wish you to follow and the
form we wish the comfort letter to take.

                                        Very truly yours,

                                        ........................................
                                        (Goldman, Sachs & Co.)

                                                                    Exhibit 10.1


                               NETWORK PLUS CORP.

                            1998 STOCK INCENTIVE PLAN

1.       PURPOSE

         The purpose of this 1998 Stock Incentive Plan (the "Plan") of Network
Plus Corp., a Delaware corporation (the "Company"), is to advance the interests
of the Company's stockholders 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 stockholders. Except where
the context otherwise requires, the term "Company" shall include any of the
Company's present or future subsidiary corporations, 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 (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan. Each 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. 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 relating to or under the Plan made in
good faith.

         (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





<PAGE>   2


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"). All
references in the Plan to the "Board" shall mean the Board or a Committee of 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 8,
Awards may be made under the Plan for up to 1,400,000 shares of common stock,
$.01 par value per share, of the Company (the "Common Stock"). 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 8,
for Awards granted after the Common Stock is registered under the Securities
Exchange Act of 1934 (the "Exchange Act"), the maximum number of shares of
Common Stock with respect to which an Award may be granted to any Participant
under the Plan shall be 700,000 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.

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.



                                      -2-
<PAGE>   3
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 by delivery to
the Company of a written notice of exercise signed by the proper person or by
any other form of notice (including electronic notice) approved by the Board
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 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, in its sole discretion,
otherwise provide in an option agreement, by (i) delivery of an irrevocable and
unconditional undertaking by a creditworthy broker to deliver promptly to the
Company sufficient funds to pay the exercise price or (ii) delivery by the
Participant to the Company of a copy of irrevocable and unconditional
instructions to a creditworthy broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price;

                  (3)      when the Common Stock is registered under the
Exchange Act, by delivery of shares of Common Stock owned by the Participant
valued at their fair market value as determined by (or in a manner approved 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;

                  (4)      to the extent permitted by the Board, in its sole
discretion by (i) delivery of a promissory note of the Participant to the
Company on terms determined by the Board, or (ii) payment of such other lawful
consideration as the Board may determine; or

                  (5)      by any combination of the above permitted forms of
payment.

<PAGE>   4



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, a
"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.

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.       ADJUSTMENTS FOR CHANGES IN COMMON STOCK AND CERTAIN OTHER EVENTS

                  (a)      CHANGES IN CAPITALIZATION. In the event of any stock
split, reverse stock split, stock dividend, recapitalization, combination of
shares, reclassification of shares, spin-off or other similar change in
capitalization or 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 per-Participant limit set forth in Section 4(b), (iii)
the number and class of securities and exercise price per share subject to each
outstanding Option, (iv) the repurchase price per share subject to each
outstanding Restricted Stock Award, and (v) the terms of each other outstanding
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



                                       -4-


<PAGE>   5


such an adjustment (or substitution) is necessary and appropriate. If this
Section 8(a) applies and Section 8(c) also applies to any event, Section 8(c)
shall be applicable to such event, and this Section 8(a) shall not be
applicable.

         (b)      LIQUIDATION OR DISSOLUTION. In the event of a proposed
liquidation or dissolution of the Company, the Board shall upon written notice
to the Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

         (c)      ACQUISITION AND CHANGE IN CONTROL EVENTS

                  (1)      DEFINITIONS

                           (A)      An "Acquisition Event" shall mean:

                                    (i)      any merger or consolidation of the
Company with or into another entity as a result of which the Common Stock is
converted into or exchanged for the right to receive cash, securities or other
property; or

                                    (ii)     any exchange of shares of the
Company for cash, securities or other property pursuant to a statutory share
exchange transaction.

                           (B)      A "Change in Control Event" shall mean:

                                    (i)      the acquisition by an individual,
entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) (a "Person")
of beneficial ownership of any capital stock of the Company if, after such
acquisition, such Person beneficially owns (within the meaning of Rule 13d-3
promulgated under the Exchange Act) 50% or more of either (x) the
then-outstanding shares of common stock of the Company (the "Outstanding Company
Common Stock") or (y) the combined voting power of the then-outstanding

employee benefit plan (or related

trust) sponsored or maintained by the Company or any corporation controlled by
the Company, (C) any acquisition by any corporation pursuant to a Business
Combination (as defined below) which complies with clauses (x) and (y) of
subsection (ii) of this definition or (D) any acquisition by Robert T. Hale,
Robert T. Hale, Jr., or any member of their immediate families, or any trust,
partnership, corporation or other entity controlled directly or indirectly by,
or any trust for the benefit of, Robert T. Hale, Robert T. Hale, Jr., or any
member of their immediate families (each such party is referred to herein as an
"Exempt Person"); or

                                    (ii)     the consummation of a merger,
consolidation, reorganization or statutory share exchange involving the Company
or a sale or other disposition of all or substantially all of the assets of the
Company (a "Business Combination"), unless, immediately following such Business
Combination, each of the following two conditions is satisfied: (x) all or
substantially all of the individuals and entities who were the beneficial owners
of the Outstanding Company Common Stock and Outstanding Company Voting
Securities immediately prior to such Business Combination beneficially own,
directly or indirectly, more than 50% of the then-outstanding shares of common
stock and the combined voting power of the then-outstanding securities entitled
to vote generally in the election of directors, respectively, of the resulting
or acquiring corporation in such Business Combination (which shall include,
without limitation, a corporation which as a result of such transaction owns the
Company or substantially all of the Company's assets either directly or through
one or more subsidiaries) (such resulting or acquiring corporation is referred
to herein as the "Acquiring Corporation") in substantially the same proportions
as their ownership of the Outstanding Company Common Stock and Outstanding
Company Voting Securities, respectively, immediately prior to such Business
Combination and (y) no Person (excluding any Exempt Person, the Acquiring
Corporation or any employee benefit plan or related trust maintained or
sponsored by the Company or by the Acquiring Corporation) beneficially owns,
directly or indirectly, 50% or more of the then-outstanding shares of common
stock of the Acquiring Corporation, or of the combined voting power of the
then-outstanding securities of such corporation entitled to vote generally in
the election of directors (except to the extent that such ownership existed
prior to the Business Combination).

                           (C)      "Good Reason" shall mean any significant
diminution in the Participant's title, authority, or responsibilities from and
after such Acquisition Event or Change in Control Event, as the case may be, or
any reduction in the annual cash compensation payable to the Participant from
and after such Acquisition Event or Change in Control Event, as the case may be,
or the relocation of the place of business at which the Participant is
principally located to a location that is greater than 50 miles from the current
site.

                           (D)      "Cause" shall mean any (i) willful failure
by the Participant, which failure is not cured within 30 days of written notice
to the




                                       -6-


<PAGE>   7


Participant from the Company, to perform his or her material responsibilities to
the Company or (ii) willful misconduct by the Participant which affects the
business reputation of the Company. The Participant shall be considered to have
been discharged for "Cause" if the Company determines, within 30 days after the
Participant's resignation, that discharge for Cause was warranted.

                  (2)      EFFECT ON OPTIONS

                           (A)      ACQUISITION EVENT. Upon the occurrence of an
Acquisition Event (regardless of whether such event also constitutes a Change in
Control Event), or the execution by the Company of any agreement with respect to
an Acquisition Event (regardless of whether such event will result in a Change
in Control Event), the Board shall provide that all outstanding Options shall be
assumed, or equivalent options shall be substituted, by the acquiring or
succeeding corporation (or an affiliate thereof). If such Acquisition Event also
constitutes a Change in Control Event, except to the extent specifically
provided to the contrary in the instrument evidencing any Option or any other
agreement between a Participant and the Company, the Option shall continue to
become vested in accordance with the original vesting schedule set forth in such
Option; provided, however, that such Options shall become immediately
exercisable in full if, on or prior to the first anniversary of the date of the
consummation of the Acquisition Event, the Participant's employment with the
Company or the acquiring or succeeding corporation is terminated for Good Reason
by the Participant or is terminated without Cause by the Company or the
acquiring or succeeding corporation.

                                    For purposes hereof, an Option shall be
considered to be assumed if, following consummation of the Acquisition Event,
the Option confers the right to purchase, for each share of Common Stock subject
to the Option immediately prior to the consummation of the Acquisition Event,
the consideration (whether cash, securities or other property) received as a
result of the Acquisition Event by holders of Common Stock for each share of
Common Stock held immediately prior to the consummation of the Acquisition Event
(and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding shares of
Common Stock); provided, however, that if the consideration received as a result
of the Acquisition Event is not solely common stock of the acquiring or
succeeding corporation (or an affiliate thereof), the Company may, with the
consent of the acquiring or succeeding corporation, provide for the
consideration to be received upon the exercise of Options to consist solely of
common stock of the acquiring or succeeding corporation (or an affiliate
thereof) equivalent in fair market value to the per share consideration received
by holders of outstanding shares of Common Stock as a result of the Acquisition
Event.

                                    Notwithstanding the foregoing, if the
acquiring or succeeding corporation (or an affiliate thereof) does not agree to
assume, or substitute





                                       -7-


<PAGE>   8


for, such Options, then the Board shall, upon written notice to the
Participants, provide that all then unexercised Options will become exercisable
in full as of a specified time prior to the Acquisition Event and will terminate
immediately prior to the consummation of such Acquisition Event, except to the
extent exercised by the Participants before the consummation of such Acquisition
Event; provided, however, that in the event of an Acquisition Event 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
Acquisition Event (the "Acquisition Price"), then the Board may instead provide
that all outstanding Options shall terminate upon consummation of such
Acquisition Event and that each Participant 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.

                           (B)      CHANGE IN CONTROL EVENT THAT IS NOT AN
ACQUISITION EVENT. Upon the occurrence of a Change in Control Event that does
not also constitute an Acquisition Event, except to the extent specifically
provided to the contrary in the instrument evidencing any Option or any other
agreement between a Participant and the Company, the Option shall continue to
become vested in accordance with the original vesting schedule set forth in such
Option; provided, however, that each such Option shall be immediately
exercisable in full if, on or prior to the first anniversary of the date of the
consummation of the Change in Control Event, the Participant's employment with
the Company or the acquiring or succeeding corporation is terminated for Good
Reason by the Participant or is terminated without Cause by the Company or the
acquiring or succeeding corporation.

                  (3)      EFFECT ON RESTRICTED STOCK AWARDS

                           (A)      ACQUISITION EVENT THAT IS NOT A CHANGE IN
CONTROL EVENT. Upon the occurrence of an Acquisition Event that is not a Change
in Control Event, the repurchase and other rights of the Company under each
outstanding Restricted Stock Award shall inure to the benefit of the Company's
successor and shall apply to the cash, securities or other property which the
Common Stock was converted into or exchanged for pursuant to such Acquisition
Event in the same manner and to the same extent as they applied to the Common
Stock subject to such Restricted Stock Award.

                           (B)      CHANGE IN CONTROL EVENT. Upon the occurrence
of a Change in Control Event (regardless of whether such event also constitutes
an Acquisition Event), except to the extent specifically provided to the
contrary in the instrument evidencing any Restricted Stock Award or any other
agreement between a Participant and the Company, the shares subject to the
Restricted Stock Award shall continue to become free from conditions or
restrictions in accordance with the



                                       -8-


<PAGE>   9


original schedule set forth in such Restricted Stock Award; provided, however,
that each such Restricted Stock Award shall immediately become free from all
conditions or restrictions if, on or prior to the first anniversary of the date
of the consummation of the Change in Control Event, the Participant's employment
with the Company or the acquiring or succeeding corporation is terminated for
Good Reason by the Participant or is terminated without Cause by the Company or
the acquiring or succeeding corporation.

                  (4)      EFFECT ON OTHER AWARDS

                           (A)      ACQUISITION EVENT THAT IS NOT A CHANGE IN
CONTROL EVENT. The Board shall specify the effect of an Acquisition Event that
is not a Change in Control Event on any other Award granted under the Plan at
the time of the grant of such Award.

                           (B)      CHANGE IN CONTROL EVENT. Upon the occurrence
of a Change in Control Event (regardless of whether such event also constitutes
an Acquisition Event), except to the extent specifically provided to the
contrary in the instrument evidencing any Award or any other agreement between a
Participant and the Company, each other Award shall continue to become
exercisable, realizable, vested or free from conditions or restrictions in
accordance with the original schedule set forth in such Award; provided,
however, that each such Award shall immediately become fully exercisable,
realizable, vested or free from conditions or restrictions if, on or prior to
the first anniversary of the date of the consummation of the Change in Control
Event, the Participant's employment with the Company or the acquiring or
succeeding corporation is terminated for Good Reason by the Participant or is
terminated without Cause by the Company or the acquiring or succeeding
corporation.

9.       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 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.




                                       -9-


<PAGE>   10


         (c)      BOARD DISCRETION. Except as otherwise provided by the Plan,
each Award may be made alone or in addition or in relation to any other Award.
The terms of each 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)      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. Except as the Board may
otherwise provide in an Award, when the Common Stock is registered under the
Exchange Act, Participants may satisfy such tax obligations in whole or in part
by delivery of 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.

         (f)      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.

         (g)      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.

         (h)      ACCELERATION. The Board may at any time provide that any
Options shall become immediately exercisable in full or in part, that any
Restricted Stock



                                      -10-


<PAGE>   11


Awards shall be free of restrictions in full or in part or that any other 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.

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.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

         (c)      EFFECTIVE DATE AND TERM OF PLAN. The Plan shall become
effective on the date on which it is adopted by the Board. No Awards shall be
granted under the Plan after the completion 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 stockholders, 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.

         (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.



                                   Adopted by the Board of Directors on
                                   July 15, 1998

incentive to remain as directors of the Company.

2.       ADMINISTRATION

         The Board of Directors (the "Board") shall supervise and administer the
Plan. Grants of stock options under the Plan and the amount and nature of the
awards to be granted shall be automatic in accordance with Section 5. However,
all questions of interpretation of the Plan or of any options issued under it
shall be determined by the Board and such determination shall be final and
binding upon all persons having an interest in the Plan.

subsidiary of the Company shall be eligible to participate in the Plan.

         (a)      The maximum number of shares which may be issued under the
Plan shall be 100,000 shares of the Company's Common Stock, $.01 par value per
share ("Common Stock"), subject to adjustment as provided in Section 9 of the
Plan.

         (b)      If any outstanding option under the Plan for any reason
expires or is terminated without having been exercised in full, the shares
allocable to the unexercised portion of such option shall again become available
for grant pursuant to the Plan.

         (c)      All options granted under the Plan shall be nonqualified
options not entitled to special tax treatment under Section 422 of the Internal
Revenue Code of 1986, as amended to date and as it may be amended from time to
time (the "Code").

5.       TERMS, CONDITIONS AND FORM OF OPTIONS

         Each option granted under the Plan shall be evidenced by a written
agreement in such form as the Board shall from time to time approve, which
agreements shall comply with and be subject to the following terms and
conditions:

         (a)      OPTION GRANTS.

                  (1)      Upon the approval of the Plan by the stockholders of
the Company, the Company shall grant to each eligible director an option for
5,000 shares of Common Stock.

                  (2)      Upon the initial election of any eligible director as
a director of the Company following the approval of the Plan by the stockholders
of the Company, the Company shall grant to such director an option for 5,000
shares of Common Stock. No person serving as a director upon the approval of
this Plan by the stockholders of the Company shall receive such an option.

                  (3)      On the date of each annual meeting of stockholders of
the Company following the approval of the Plan by the stockholders of the
Company, the Company shall grant to each eligible director who continues to
serve as a director immediately following such annual meeting an option for
2,500 shares of Common Stock. If in any calendar year no annual meeting of
stockholders is held prior to August 1, then in lieu of receiving such an option
grant on the date of the annual meeting of stockholders for such year, each
eligible director shall receive an option grant for 2,500 shares on August 1 of
such year. Notwithstanding the foregoing no director shall receive an option
under this Section 5(a)(3) if he or she received an option under Section 5(a)(1)
or (2) above within six (6) months prior to the date of grant under this Section
5(a)(3).

         (b)      OPTION EXERCISE PRICE. The option exercise price per share for
each option granted under the Plan shall equal (i) the last reported sales price
per share of the Company's Common Stock on the Nasdaq National Market (or, if
the Company is traded on a nationally recognized securities exchange on the date
of grant, the reported closing sales price per share of the Company's Common
Stock by such exchange) on the date of grant (or if no such price is reported on
such date such price as reported on the nearest preceding day) or (ii) if the
Common Stock is not traded on the Nasdaq National Market or such an exchange,
the fair market value per share on the date of grant as most recently determined
by the Board.

         (c)      OPTIONS NON-TRANSFERABLE. Except as otherwise provided in the
agreement evidencing the option grant, each option granted under the Plan by its
terms shall not be transferable by the optionee other than by will, or by the
laws of descent and distribution, and shall be exercised during the lifetime of
the optionee



                                      -2-
<PAGE>   3

only by the optionee. Except as otherwise provided in the agreement evidencing
the option grant, no option or interest therein may be transferred, assigned,
pledged or hypothecated by the optionee during the optionee's lifetime, whether
by operation of law or otherwise, or be made subject to execution, attachment or
similar process.

         (d)      EXERCISE PERIOD. Each option shall become exercisable on a
cumulative basis as to 25% of the shares subject to the option on each of the
first, second, third and fourth anniversaries of the date of grant of such
option. Except as otherwise provided in the option agreements, in the event an
optionee ceases to serve as a director, each such option may be exercised by the
optionee (or, in the event of her death, by her administrator, executor or
heirs), at any time within 12 months after the optionee ceases to serve as a
director, to the extent such option was exercisable at the time of such
cessation of service. Notwithstanding the foregoing, no option shall be
exercisable after the expiration of 10 years from the date of grant.

         (e)      EXERCISE PROCEDURE. Options may be exercised only by written
notice to the Company at its principal office accompanied by (i) payment in cash
of the full consideration for the shares as to which they are exercised or (ii)
an irrevocable undertaking by a broker to deliver promptly to the Company
sufficient funds to pay the exercise price or delivery of irrevocable
instructions to a broker to deliver promptly to the Company cash or a check
sufficient to pay the exercise price.

6.       ASSIGNMENTS

         The rights and benefits of participants under the Plan may not be
assigned, whether voluntarily or by operation of law, except as provided in
Section 5(c).

7.       EFFECTIVE DATE

         The Plan shall become effective immediately upon its approval by the
stockholders of the Company.

8.       LIMITATION OF RIGHTS

         (a)      NO RIGHT TO CONTINUE AS A DIRECTOR. Neither the Plan, nor the
granting of an option nor any other action taken pursuant to the Plan, shall
constitute or be evidence of any agreement or understanding, express or implied,
that the Company will retain a director for any period of time.





                                       -3-


<PAGE>   4


         (b)      NO STOCKHOLDERS' RIGHTS FOR OPTIONS. An optionee shall have no
rights as a stockholder with respect to the shares covered by such optionee's
options until the date of the issuance to such optionee of a stock certificate
therefor, and no adjustment will be made for dividends or other rights (except
as provided in Section 9) for which the record date is prior to the date such
certificate is issued.

9.       ADJUSTMENTS FOR CHANGES IN COMMON STOCK AND CERTAIN OTHER EVENTS

         (a)      CHANGES IN CAPITALIZATION. In the event of any stock split,
reverse stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or 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 securities and exercise price per share subject to
each outstanding option and (iii) the number and class of securities subject to
options issuable under Section 5(a) of this Plan shall be appropriately adjusted
by the Company (or substituted options 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 9(a) applies and
Section 9(c) also applies to any event, Section 9(c) shall be applicable to such
event, and this Section 9(a) shall not be applicable.

         (b)      LIQUIDATION OR DISSOLUTION. In the event of a proposed
liquidation or dissolution of the Company, the Board shall upon written notice
to the optionees provide that all then unexercised options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date.

         (c)      ACQUISITION AND CHANGE IN CONTROL EVENTS

                  (1)      DEFINITIONS

                           (A)      An "Acquisition Event" shall mean:

                                    (i)      any merger or consolidation of the
Company with or into another entity as a result of which the Common Stock is
converted into or exchanged for the right to receive cash, securities or other
property; or

                                    (ii)     any exchange of shares of the
Company for cash, securities or other property pursuant to a statutory share
exchange transaction.

                           (B)      A "Change in Control Event" shall mean:

                                    (i)      the acquisition by an individual,
entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) (a "Person")
of beneficial ownership of any capital stock of the Company if, after such
acquisition, such Person beneficially owns (within the meaning of Rule 13d-3
promulgated under the Exchange Act) 50% or more of either (x) the
then-outstanding shares of common stock of the Company (the "Outstanding Company
Common Stock") or (y) the combined voting power of the then-outstanding
securities of the Company entitled to vote generally in the election of
directors (the "Outstanding Company Voting Securities"); PROVIDED, HOWEVER, that
for purposes of this subsection (i), the following acquisitions shall not
constitute a Change in Control Event: (A) any acquisition directly from the
Company (excluding an acquisition pursuant to the exercise, conversion or
exchange of any security exercisable for, convertible into or exchangeable for
common stock or voting securities of the Company, unless the Person exercising,
converting or exchanging such security acquired such security directly from the
Company or an underwriter or agent of the Company), (B) any acquisition by any
employee benefit plan (or related trust) sponsored or maintained by the Company
or any corporation controlled by the Company, (C) any acquisition by any
corporation pursuant to a Business Combination (as defined below) which complies
with clauses (x) and (y) of subsection (ii) of this definition or (D) any
acquisition by Robert T. Hale, Robert T. Hale, Jr., or any member of their
immediate families, or any trust, partnership, corporation or other entity
controlled directly or indirectly by, or any trust for the benefit of, Robert T.
Hale, Robert T. Hale, Jr., or any member of their immediate families (each such
party is referred to herein as an "Exempt Person"); or

                                    (ii)     the consummation of a merger,
consolidation, reorganization or statutory share exchange involving the Company
or a sale or other disposition of all or substantially all of the assets of the
Company (a "Business Combination"), unless, immediately following such Business
Combination, each of the following two conditions is satisfied: (x) all or
substantially all of the individuals and entities who were the beneficial owners
of the Outstanding Company Common Stock and Outstanding Company Voting
Securities immediately prior to such Business Combination beneficially own,
directly or indirectly, more than 50% of the then-outstanding shares of common
stock and the combined voting power of the then-outstanding securities entitled
to vote generally in the election of directors, respectively, of the resulting
or acquiring corporation in such Business Combination (which shall include,
without limitation, a corporation which as a result of such transaction owns the
Company or substantially all of the Company's assets either directly or through
one or more subsidiaries) (such resulting or acquiring corporation is referred
to herein as the "Acquiring Corporation") in substantially the same proportions
as their ownership of the Outstanding Company Common Stock and Outstanding
Company Voting Securities, respectively, immediately prior to such

Business Combination and (y) no Person (excluding any Exempt Person, the
Acquiring Corporation or any employee benefit plan or related trust maintained
or sponsored by the Company or by the Acquiring Corporation) beneficially owns,
directly or indirectly, 50% or more of the then-outstanding shares of common
stock of the Acquiring Corporation, or of the combined voting power of the
then-outstanding securities of such corporation entitled to vote generally in
the election of directors (except to the extent that such ownership existed
prior to the Business Combination).

                  (2)      EFFECT ON OPTIONS

                           (A)      ACQUISITION EVENT. Upon the occurrence of an
Acquisition Event (regardless of whether such event also constitutes a Change in
Control Event), or the execution by the Company of any agreement with respect to
an Acquisition Event (regardless of whether such event will result in a Change
in Control Event), the Board shall provide that all outstanding options shall be
assumed, or equivalent options shall be substituted, by the acquiring or
succeeding corporation (or an affiliate thereof); PROVIDED THAT if such
Acquisition Event also constitutes a Change in Control Event, such assumed or
substituted options shall be immediately exercisable in full upon the occurrence
of such Acquisition Event.

                                    For purposes hereof, an option shall be
considered to be assumed if, following consummation of the Acquisition Event,
the option confers the right to purchase, for each share of Common Stock subject
to the option immediately prior to the consummation of the Acquisition Event,
the consideration (whether cash, securities or other property) received as a
result of the Acquisition Event by holders of Common Stock for each share of
Common Stock held immediately prior to the consummation of the Acquisition Event
(and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding shares of
Common Stock); provided, however, that if the consideration received as a result
of the Acquisition Event is not solely common stock of the acquiring or
succeeding corporation (or an affiliate thereof), the Company may, with the
consent of the acquiring or succeeding corporation, provide for the
consideration to be received upon the exercise of options to consist solely of
common stock of the acquiring or succeeding corporation (or an affiliate
thereof) equivalent in fair market value to the per share consideration received
by holders of outstanding shares of Common Stock as a result of the Acquisition
Event.

                                    Notwithstanding the foregoing, if the
acquiring or succeeding corporation (or an affiliate thereof) does not agree to
assume, or substitute for, such options, then the Board shall, upon written
notice to the optionees, provide that all then unexercised options will become
exercisable in full as of a specified time prior to the Acquisition Event and
will terminate immediately prior to the consummation of such Acquisition Event,
except to the extent exercised by the optionees before the consummation of such
Acquisition Event; provided, however, in




                                       -6-


<PAGE>   7


the event of an Acquisition Event 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 Acquisition Event (the "Acquisition
Price"), then the Board may instead provide that all outstanding options shall
terminate upon consummation of such Acquisition Event and that each optionee
shall receive, in exchange therefor, a cash payment equal to the amount (if any)
by which (i) the Acquisition Price multiplied by the number of shares of Common
Stock subject to such outstanding options (whether or not then exercisable),
exceeds (ii) the aggregate exercise price of such options.

                           (B)      CHANGE IN CONTROL EVENT THAT IS NOT AN
ACQUISITION EVENT. Upon the occurrence of a Change in Control Event that does
not also constitute an Acquisition Event, all options then-outstanding shall
automatically become immediately exercisable in full.

         10.      AMENDMENT OF THE PLAN

                  The Board may at any time, and from time to time, suspend or
discontinue the Plan or modify or amend it in any respect whatsoever.

         11.      GOVERNING LAW

                  The Plan and all determinations made and actions taken
pursuant hereto shall be governed by the laws of the State of Delaware.



                                  Adopted by the Board of Directors on
                                  July 15, 1998

                                  Approved by the stockholders on

                           AGREEMENT FOR THE PROVISION

                                       OF

                       FIBER OPTIC FACILITIES AND SERVICES

                                     BETWEEN

                          NORTHEAST OPTIC NETWORK, INC.

                                       AND

                               NETWORK PLUS, INC.


Effective as of July 17, 1998 (the "Effective Date") Network Plus Inc., a
Massachusetts corporation, having an office at 234 Copeland Street, Quincy, MA
02169 ("Network Plus"), and NorthEast Optic Network, Inc., a Delaware
corporation, having an office at 391 Totten Pond Road, Suite 401, Waltham, MA
02154 ("NEON"), (collectively, the "Parties") agree as follows:

BACKGROUND. NEON and its affiliates are the exclusive owners of The New England
Optical Network (the "NEON Network"), a communication system located on property
owned by electric utility companies and others. Network Plus seeks to use part
of the NEON Network to operate its communication network. NEON is willing to
grant Network Plus the indefeasible right to use ("IRU") certain of NEON's
facilities and fiber optics filaments in exchange for certain payments and
annual fees.

1.       THE NETWORK PLUS FIBERS. Upon completion pursuant to Section 2.3, NEON
shall be deemed to have conveyed to Network Plus an IRU for [*] AT&T True Wave
dark optical fibers to be specifically identified between NEON's Boston
Metropolitan Area POP and NEON's New York City, NY POP including any connectors
thereto as depicted in Exhibit 1, attached hereto. NEON will dedicate these [*]
fibers to Network Plus's use along the cable system (the "Network Plus Fibers"
or the "Network Plus Fiber Network") and represents and warrants that no other
party shall use such dedicated fibers at any time during the term of this
Agreement.

2.       TERM, TERMINATION, USE AND COMPLETION OF NETWORK PLUS FIBER NETWORK.

2.1      TERM. The initial term of the IRU conveyed for the Network Plus Fiber
Network shall be [**] years from the date the Network Plus Fiber Network is
completed pursuant to Section 2.3 (the "Initial Term"). Unless Network Plus
gives NEON written notice at least [***********] days prior to the end of the
Initial Term, the term shall be automatically extended until the earlier of (i)
the end of the economic useful life of the Network Plus Fiber Network or (ii) as
to specific affected portions of the Network Plus Fiber Network, the expiration
of NEON's right to use certain rights of way and other facilities under its
agreement with Northeast Utilities Service Company dated September 27, 1994 (the
period of such extension being referred to herein as the "Renewal Period");
PROVIDED, however, that NEON's obligations pursuant to Sections 5.1, 5.2, 5.3,
5.4 (except for the last sentence thereof), 5.5, 11.1 and 11.2 shall terminate
at the end of the Initial Term and shall not apply during any Renewal Period.
[******************************************************************************
******].

2.2      USE. Network Plus may use the fibers covered by the IRU for (and only
for) any lawful purpose.

2.3      COMPLETION. The Network Plus Fiber Network as a whole shall be
complete, operational and available for use by Network Plus by April 1, 1999
(the "Completion Date"). Completion of the Network Plus Fiber Network shall be
deemed to have occurred when the Network Plus Fibers are in conformance in all
material respects with the technical specifications (the "Specifications") set
forth in Exhibit 2.3, and all acceptance testing has been completed to Network
Plus's reasonable satisfaction (the "Acceptance Date").

2.4      COMPLETION SCHEDULE. If completion of the Network Plus Fiber Network
does not take place by the Completion Date, a penalty of $[**] per day shall
accrue up to a total aggregate penalty of $[**], and that penalty charge shall
be due and payable by NEON 30 days following the Completion Date or on the
Acceptance Date, whichever shall occur first. If completion of the Network Plus
Fiber Network does not occur





<PAGE>   2
Confidential Materials omitted and filed separately with the Securities and 
Exchange Commission. Asterisks denote omissions.


within 30 days of the Completion Date, Network Plus shall have the right to
terminate this Agreement immediately upon written notice to NEON.

         The parties agree that they will negotiate in good faith a mutually
agreeable project plan (the "Project Plan") relating to the construction and
implementation of the Network Plus Fiber Network. This Project Plan will
include, without limitation, target dates for the construction of certain
segments, financial penalties in the event that NEON fails to satisfy its
obligations with respect to such target dates, and such other terms as the
parties may negotiate. Except as expressly agreed by the Parties in writing, (i)
such Project Plan, including all agreements and understandings between the
Parties relating to the execution of such Project Plan, shall not affect the
rights and obligations of the Parties as set forth in this IRU Agreement,
including but not limited to the first two sentences of this Section 2.4 and
(ii) such Project Plan shall not be deemed to be an amendment to the terms of
this IRU Agreement.

2.5      TERMINATION. Notwithstanding any provision contained in this Agreement
to the contrary, at any time after the Acceptance Date, Network Plus shall have
the option, in its sole discretion and for any reason, to terminate this
Agreement upon [***] days' prior written notice to NEON, without further
liability other than to pay the monthly lease charges specified in Section 4.1
(as adjusted under Section 4.2 and 4.3, as applicable) for months in the Initial
Term prior to the effective date of such termination.

2.6      RIGHT OF NOTICE. In the event that NEON contemplates entering into a
transaction with a third party as a result of which fewer than [****] fibers
would remain available on any route in the NEON Network, NEON shall notify
Network Plus in writing at least [****] days prior to entering into a written
agreement with respect to such transaction. NEON shall have no obligation to
disclose the terms of such contemplated transaction, nor shall Network Plus be
entitled to a right of first refusal or any other right (other than a right of
notice) pursuant to this Section 2.6.

3.       DELIVERABLES.

3.1      DOCUMENTATION. In accordance with the time frame set forth in Section
3.2, herein, NEON shall deliver to Network Plus complete documentation regarding
the as-built condition of the Network Plus Fibers. This documentation
(hereinafter referred to as the "Deliverables") shall consist of the following,
which NEON represents and warrants will be true and correct in all material
respects:

         (a)      As-Built Drawings reflecting the specifications set forth in
                  Exhibit 3.1, attached hereto and incorporated herein.

         (b)      Technical specifications of the optical fiber cable,
                  associated splices and other equipment used in installing and
                  providing the Network Plus Fibers.

         (c)      List of names and 7 x 24 telephone numbers for NEON personnel
                  responsible for maintaining and repairing the Network Plus
                  Fibers.

3.2      DELIVERY AND NUMBER OF COPIES. The Deliverables shall be supplied
within 30 days after the Acceptance Date, provided, however, that the
Deliverable described in Section 3.1(c) shall be supplied upon execution of the
Agreement. NEON shall provide 2 copies of the Deliverables to Network Plus.

3.3      WORKING VERSIONS. Upon execution of this Agreement, NEON will supply to
Network Plus working versions of the Deliverables specified in Sections 3.1(a)
and (b), and shall supply updated versions of the Deliverables every [*********]
days thereafter, or, if sooner, immediately upon any material change thereto.

4.       PAYMENT TERMS.

4.1      LEASE RATE. The lease rate for the Network Plus Fibers will be $[**]
per month for each month during the Initial Term. The first payment will be due
30 days after the Acceptance Date. Network Plus shall have the right to set off
against such payments any and all amounts owed by NEON to Network Plus (or to a
Network Plus supplier) under this Agreement, including without limitation
reimbursement for all



                                       -2-

<PAGE>   3

Exchange Commission. Asterisks denote omissions.



costs associated with matters undertaken by Network Plus pursuant to the terms
of this Agreement that are to be at NEON's cost and expense.

4.2      RATE ADJUSTMENTS. NEON agrees that the monthly lease rate for the
Network Plus Fibers will be the lowest price per fiber mile under the Term
hereof and for the fiber strand count herein charged by NEON for dark fiber
leases on the route on which the Network Plus Fibers are located. Should NEON
contract to lease dark fiber to a third party at a lower price per fiber mile on
the same Term for the same fiber count, then effective as of the commencement of
such lease, the lease rate payable hereunder for the relevant Network Plus
Fibers shall be lowered to the same price per fiber mile as in said third party
contract. NEON and Network Plus shall promptly thereafter execute an appropriate
amendment to this Agreement to document such new lease amount.

4.3      INFLATION. On January 1, 1999 and on January 1st of each year
thereafter during the Initial Term, the lease rate referred to in Section 4.1
hereof shall be increased by [**] of the percentage increase in the Consumer
Price Index for Urban Wage Earners, United States, Base 1982-84 = 100, issued by
the Bureau of Labor Statistics of the United States Department of Labor
("CPI-W"), for the immediately preceding calendar year. If the government body
issuing the CPI-W ceases to use the 1982-84 average of 100 as the basis for
calculation, the CPI-W shall be adjusted to the figure that would have been
arrived at had the manner of so calculating the CPI-W not been so changed. If
the CPI-W (or a successor or a substitute index) ceases to be published, or
ceases to be generally recognized as an index of inflation, the parties hereto
shall select and substitute an index which is mutually acceptable, published by
a governmental or other disinterested body with appropriate reconciliation of
the base of the substituted index with the base of the CPI-W.

4.4      SALES TAX. In addition to the lease rate, as adjusted periodically by
Sections 4.2 and 4.3, Network Plus shall be responsible for any and all sales
taxes levied on the grant of the IRU for the Network Plus Fiber Network and the
lease payments pursuant to Section 4.1.

5.       MAINTENANCE AND REPAIR OF THE NETWORK PLUS FIBER NETWORK.

5.1      EMERGENCY MAINTENANCE. During the Initial term, NEON shall use its best
efforts to respond to any failure, interruption or impairment in the operation
of Network Plus Fibers within [**] hours after receiving a report from Network
Plus of any such failure, interruption or impairment, and Network Plus reserves
the right to have a representative present to assist in any maintenance or
repair. NEON will use its best efforts to have all fibers restored within [**]
hours of any failure, interruption or impairment. When trouble is encountered on
the Network Plus Fibers, Network Plus, to assist NEON in its maintenance
activities, will diagnose the trouble through OTDR testing, if possible, and
ascertain and notify NEON of the location address to the nearest cross street.
NEON shall use its best efforts to perform maintenance and repair to correct any
failure, interruption or impairment in the operation of the Network Plus Fibers
in accordance with the procedures set forth in Exhibit 5.1 attached hereto and
incorporated herein. In the event NEON fails to perform any necessary Emergency
Maintenance in accordance with the procedures set forth in Exhibit 5.1, Network
Plus shall have the right, with notice to NEON, but not the obligation, to
immediately undertake such Emergency Maintenance of the Network Plus Fibers, at
NEON's sole cost and expense. NEON shall not be required to provide emergency
maintenance services during any Renewal Term, except as mutually agreed by each
of the parties in writing.

5.2      ROUTINE MAINTENANCE. NEON will schedule and perform specific periodic
maintenance and repair checks and services during the Initial Term, as set forth
in NEON's Routine Maintenance Standards, attached hereto as Exhibit 5.2, from
time to time on the Network Plus Fibers, at NEON's reasonable discretion, upon
21 days' advance notice to Network Plus, or at Network Plus's reasonable
request. Network Plus and NEON will schedule such Routine Maintenance at
mutually agreeable times, and NEON shall reschedule any Routine Maintenance as
reasonably requested by Network Plus in writing at least [**] days prior to the
date of any scheduled Routine Maintenance. Network Plus may request reasonable
Routine Maintenance by delivering to NEON, not more than twice per agreement
year, for NEON's approval, a statement detailing the maintenance checks and
services Network Plus desires to be performed on the Network Plus Fibers. In the
event NEON fails to perform any Routine Maintenance in accordance with NEON's
Routine Maintenance Standards, after written notice by Network Plus, Network
Plus shall have the right, but not the obligation, to undertake such Routine



                                       -3-

Exchange Commission. Asterisks denote omissions.


Maintenance of the Network Plus Fibers, at NEON's sole cost and expense, using
contractors pre-approved by NEON.

5.3      OUTAGE CREDITS. Network Plus shall receive a credit ("Outage Credit")
against the fiber lease rate owed NEON hereunder in the event that the Network
Plus Fibers do not operate within the parameters of the Specifications. The
Outage Credit shall be equal to [**]th of the monthly lease rate, as adjusted,
multiplied by the number of fibers out of compliance for each hour or portion
thereof of noncompliance, as measured from the time Network Plus notifies NEON
of the problem until the time NEON, or Network Plus in the event of self help,
has corrected the problem.

5.4      SELF-HELP. In the event NEON, or others acting in Neon's behalf, after
written notice to Network Plus, at any time during the term of this Agreement
discontinues maintenance and/or repair of the Network Plus Fibers, Network Plus,
or others acting in Network Plus's behalf, shall have the right, but not the
obligation, to thereafter provide for the maintenance and repair of the Network
Plus Fibers, at NEON's sole cost and expense. Any such discontinuance shall be
upon no less than 6 months' prior written notice to Network Plus. In the event
of such discontinuance or during any Renewal Period, NEON shall obtain for
Network Plus, or others acting in Network Plus's behalf, adequate access to the
Rights-of-Way (as hereinafter defined) on or within which the Network Plus
fibers are located, for the purpose of permitting Network Plus, or others acting
in Network Plus's behalf, to undertake such maintenance and repair of the
Network Plus Fibers; provided, however, that such access shall be provided by
NEON at Network Plus's sole cost and expense during any Renewal Period.

5.5      REPLACEMENT. In the event all or any part of the Network Plus Fiber
Network shall require replacement during the Initial Term of this Agreement,
such replacement shall be made as soon as reasonably practical, at NEON's sole
cost and expense. If replacement of the Network Plus Fibers is required in
accordance with the preceding sentence, NEON shall give Network Plus written
notice of such replacement as soon as reasonably practicable before the
replacement optical fiber cable is ordered from the manufacturer. Network Plus
shall have the option, in its sole discretion, to be exercised by written notice
to NEON within 20 days of Network Plus's receipt of notice from NEON to: (a)
accept the proposed replacement optical fiber cable per Specifications; or (b)
increase the number of optical fiber strands to be installed in such new cable
for Network Plus's use.

5.6      ESCALATION. Within [**********] days after execution of this Agreement,
the parties shall agree in writing upon a mutually acceptable plan for
escalating troubles, outages and similar matters.

5.7      DAMAGE BY NETWORK PLUS. In the event that the electronics, optronics or
other technologies employed by Network Plus interfere or adversely affect the
use of or damage any portion of the NEON Network, including the Network Plus
Fibers, (i) NEON shall be entitled to those indemnification rights set forth in
Section 13.3 hereof, and (ii) NEON shall have no maintenance obligation or
outage credit liability pursuant to this Section 5 as a result of such outage or
damage.

6.       WARRANTIES.

6.1      CONFORMITY WITH SPECIFICATIONS. NEON represents and warrants that the
Network Plus Fiber Network shall: (a) be in full compliance with and operate
within the parameters of the Specifications, and (b) be fit to perform as an
optical fiber cable system; provided, however, that such warranties shall in no
way be deemed to be a limitation on or in derogation of NEON's obligations under
Section 5, herein. Any maintenance or repairs to the NEON System required as a
result of a breach of the foregoing warranties shall be performed at NEON's sole
cost and expense.

6.2      NEON CORPORATE AUTHORITY. NEON represents and warrants to Network Plus
that it has full corporate power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby by NEON have been duly and validly authorized by all
necessary corporate action on the part of NEON.

6.3      NETWORK PLUS CORPORATE AUTHORITY. Network Plus represents and warrants
to NEON that it has full corporate power and authority to execute and deliver
this Agreement and to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby by Network

Exchange Commission. Asterisks denote omissions.


Plus have been duly and validly authorized by all necessary corporate action on
the part of Network Plus.

7.       TAXES AND FEES.

7.1      GENERAL. NEON shall be responsible for and shall timely pay any and all
taxes and franchise, license and permit fees based on its use and ownership of
the Network Plus Network.

7.2      REAL ESTATE TAXES. [**]

7.3      TAXES RELATING TO NETWORK PLUS. [**]

8.       RELOCATION. If, for any reason, NEON is required by any third party,
including, but not limited to, a governmental entity, or if NEON desires, for
any other reason, to relocate any of the facilities used or required in
providing the Network Plus Fibers or to relocate any of the facilities used or
required in providing the NEON System and the Network Plus Fibers, NEON shall
give Network Plus at least 60 days' (or such lesser period of notice that NEON
may have received from such third party) prior written notice of any such
relocation and Network Plus shall be entitled to terminate this Agreement, in
accordance with the provisions, excluding the notification period, of Section
2.4 herein, by giving at least [**] days' prior written notice to NEON. In the
event this Agreement is not terminated, NEON shall relocate the Network Plus
Fibers and, to the extent NEON is not reimbursed for the cost of such relocation
by a third party, governmental entity or otherwise, NEON shall be responsible
for all the costs associated with the relocation of the Network Plus Fibers.

9.       CONDEMNATION. Upon its receipt of a formal notice of condemnation or
taking, NEON shall notify Network Plus immediately of any condemnation
proceeding filed against NEON containing the Network Plus Fiber Network or the
Utilities' property in or upon which the Network Plus Fiber Network shall have
been installed. NEON shall also notify Network Plus of any similar threatened
condemnation proceeding. If a taking or condemnation requires relocation of NEON
containing the Network Plus Fiber Network, NEON shall use its best efforts to
obtain an alternative route over which the Network Plus Fiber Network may be
relocated, at no cost to Network Plus. NEON shall be entitled to use any
condemnation proceeds otherwise payable to Network Plus to defray the reasonable
cost of such alternative route. Any excess proceeds received by NEON with
respect to Network Plus's interests shall be paid by NEON to Network Plus.
Subject to the foregoing, both parties shall be entitled, to the extent
permitted under applicable law, to participate in any condemnation proceedings
to seek to obtain compensation by either joint or separate awards for the
economic value of their respective interests. NEON shall not sell the Network
Plus Fiber Network property to an acquiring agency, authority or other party in
lieu of condemnation without prior written notice to and consent of Network
Plus.

10.      OWNERSHIP OF THE NETWORK PLUS FIBER NETWORK.

10.1     GENERAL. Network Plus shall have an undivided right of use of the
Network Plus Fibers. It is understood and agreed that NEON must and does
maintain legal title to the Network Plus Fiber Network subject to the IRU
hereunder. Notwithstanding the foregoing, it is understood and agreed as between
the parties that the grant of the IRU hereunder shall be treated for accounting
and federal and all applicable state and local tax purposes as the sale and
purchase of the Network Plus Fiber Network, and that on or after the Acceptance
Date, Network Plus shall be treated as the owner of the Network Plus Fiber
Network for such purposes; PROVIDED, however, that the IRU granted hereunder and
Network Plus's ownership status for tax, accounting and all other legal
purposes, shall revert to NEON upon the termination or expiration of this
Agreement. The parties agree to file their respective income tax returns,
property

Exchange Commission. Asterisks denote omissions.



tax returns, and other returns and reports for their respective Impositions on
such basis and, except as otherwise required by law, not to take any positions
inconsistent therewith.

10.2     REPRESENTATIONS TO THIRD PARTIES. Except as otherwise provided in this
Agreement, Network Plus shall not represent to any third party that any party
other than NEON is the legal owner of the Network Plus Fibers. NEON acknowledges
that Network Plus has contracted for the purchase of an IRU in the Network Plus
Fibers and agrees that it will not take any action which is inconsistent with
Network Plus's said position.

11.      REQUIRED RIGHTS.

11.1     MAINTENANCE OF REQUIRED RIGHTS. NEON represents and warrants that NEON
has obtained or shall use its best efforts to obtain all Required Rights and
other rights, licenses, permits and authorizations as required to construct the
Network Plus Fiber Network and shall use its best efforts to maintain in place
all Required Rights necessary to operate the Network Plus Fiber Network
throughout the Initial Term hereof. Upon Network Plus's written request, NEON
shall make available for inspection by Network Plus, at NEON's offices, copies
of all information, documents, agreements, reports, permits, drawings and
specifications that in NEON's reasonable determination are material to the grant
of the IRU to Network Plus and available to NEON including, without limitation,
the Required Rights to the extent that the terms of each such document or the
legal restrictions applicable to such information or document permits disclosure
and further as may be redacted to protect disclosure of confidential business
and proprietary terms. NEON represents and warrants that any redacted portions
of the Required Rights documents shall not materially affect the rights of
Network Plus granted hereunder. "Required Rights" means any and all rights,
licenses, authorizations, rights of way, and other agreements necessary for the
use of poles, conduit, cable, wire or other physical plant facilities, as well
as any other such rights, licenses, authorizations (including any necessary
state, tribal or federal authorizations such as environmental permits), rights
of way and other agreements necessary for the installation and use of the
Network Plus Fiber Network.

11.2     EXPIRATION OF REQUIRED RIGHTS. In the event that, despite exercising
its best efforts to do so, NEON is unable to maintain in place one or more
Required Rights throughout the Initial Term, NEON shall use commercially
reasonable efforts to provide to Network Plus a Functionally Equivalent
Communications Path at NEON's sole cost to replace the portion of the Network
Plus Fiber Network that is affected by the loss of such Required Rights.
"Functionally Equivalent Communications Path" shall mean telecommunications
capabilities that, when used in conjunction with Network Plus's electronics,
optronics or technologies (as they exist at the time of such loss of such
Required Right), provide the same communications bandwidth between the same
locations. In the event that, despite exercising commercially reasonable efforts
pursuant to this Section 11.2, NEON is unable to provide a Functionally
Equivalent Communications Path, the Term of the IRU hereunder with respect to
the affected portion of the Network Plus Fiber Network shall automatically
expire upon such expiration or termination of the Required Right, and the lease
rate pursuant to Section 4.1 hereof shall be reduced in proportion to the
reduction in the total number of fiber miles in the Network Plus Fiber Network.

12.      REGENERATORS.

12.1     SPECIFICATIONS OF SHELTER SPACE. NEON shall provide Network Plus with
[***] square feet of caged shelter space for placement of its electronics
equipment at NEON regenerator sites located along the route with 7/24 unescorted
access during the Initial Term. During any Renewal Period, NEON shall offer to
Network Plus such shelter space at a commercially reasonable rate. The Shelter
Equipment Layout is as identified in Exhibit 12.1. Network Plus shall pay NEON
for all incremental actual buildout costs associated with providing Network Plus
with secure separate shelter space and access.

12.2     BACKUP POWER. NEON will provide Network Plus with a minimum of
[**] hours of battery backup and generator power at each regenerator site.
Failure to provide such power during the Initial Term shall be deemed an Outage
for purposes of Section 5.3. During any Renewal Period, NEON shall offer to
Network Plus such backup and generator power at a commercially reasonable rate.
In addition, NEON shall permit Network Plus to install a generator plus at each
facility and shall permit Network Plus to attach its own generator to such plug
in the event Network Plus desires to do so.

12.3     ACCESS TO NETWORK. NEON shall provide Network Plus with access to the
Network Plus Fiber Network at all regeneration sites and point of presence
("POP") locations. In addition, NEON shall provide Network Plus access to the
Network Plus Fiber Network at existing cable splice points, as reasonably
requested from time to time by Network Plus. All connections shall be performed
by NEON in accordance with NEON's applicable specifications and operating
procedures as approved by Network Plus, which approval shall not be unreasonably
withheld, and shall be at Network Plus's sole cost and expense, so long as such
cost and expense have been approved in advance in writing by Network Plus.
Network Plus shall have no limitations on the types of electronics, optronics or
technologies employed to utilize the Network Plus Fiber Network fibers, subject
to mutually agreeable safety procedures and so long as such electronics,
optronics or technologies do not interfere with the use of or present a risk of
damage to any portion of the NEON Network.

13.      LIMITATION OF LIABILITY; INDEMNIFICATION.

13.1     CONSEQUENTIAL DAMAGES. Neither party shall be liable to the other party
for any indirect, special, punitive, or consequential damages (including, but
not limited to, any claim from any customer for loss of service) arising under
this Agreement or from any breach or partial breach of the provisions of this
Agreement or arising out of any act or omission of either party, its employees,
servants, contractors and/or agents. Each party agrees to use its best efforts
to include in any agreement with any third party relating to the use of NEON or
the Network Plus Fiber Network a waiver by such third party of any claim for
indirect, special, punitive or consequential damages (including, but not limited
to, any claim from any client or customer for loss of services) arising out of
or as a result of any act or omission by either party, its employees, servants,
contractors and/or agents.

13.2     CLAIMS AGAINST THIRD PARTIES. Nothing contained herein shall operate as
a limitation on the right of either party hereto to bring an action for damages,
including consequential damages, against any third party based on any acts or
omissions of such third party as such acts or omissions may affect the
construction, operation or use of NEON or the Network Plus Fiber Network
provided, however, that each party hereto shall assign such rights or claims,
execute such documents and do whatever else may be reasonably necessary to
enable the injured party to pursue any such action against such third party.

13.3     INDEMNIFICATION. Each party agrees to indemnify, defend, protect and
save the other harmless from and against any claim, damage, loss, liability,
cost, and expense (including reasonable attorney's fees) in connection with any
personal injury, including death, loss or damage to any property, or facilities
of any party (including NEON, Network Plus or any other party operating or using
any part of NEON or the Network Plus Fiber Network) arising out of or resulting
in any way from the negligent acts or negligent omissions to act of such party,
its employees, servants, contractors, and/or agents (and/or, in the case of
NEON, for the negligent acts or negligent omissions to act of any other entity
to whom it grants or has granted an IRU or otherwise leases fiber or provides
services using the fiber) in connection with the exercise of its rights and
obligations under the terms of this Agreement or any breach by such party of any
obligation contained in this Agreement.

14.      INSURANCE. Each party shall, at its own expense, secure and maintain in
force throughout the term of this Agreement, General Liability Insurance with
competent qualified issuing insurance companies, including the following
coverages: Product Liability, Hazard of Premises/Operations (including
explosion, collapse and underground coverages); Independent Contractors;
Products and Completed Operations; Blanket Contractual Liability (covering the
liability assumed in this Agreement); Personal Injury (including death); and
Broad Form Property Damage in policy or policies of insurance such that the
total available limits to all insured will not be less than $[**] Combined
Single Limit for each occurrence and $[**] aggregated for each annual period.
Such insurance may be provided in policy or policies, primary and excess,
including so-called umbrella or catastrophe forms. All policies required by this
Section 14 shall require the insurance companies to notify the other party at
least 30 days prior to the Effective Date of any cancellation or material
modification of such policies, and shall specify that the policy shall apply
without consideration for the other policies separately carried and shall state
that each insured is provided coverage as though a separate policy had been
issued to each, except the insurer's liability shall not be increased beyond the
amount for which the insurer would have been liable had only one insured been
covered and only one





                                       -7-

to any mechanics', artisans' or materialmen's lien, or other encumbrance,
chargeable to or through NEON which interferes with Network Plus's use of the
Network Plus Fiber Network or which is not fully subordinated to Network Plus's
rights under this Agreement, NEON shall promptly cause such lien or encumbrance
to be discharged and released of record (by payment, posting of bond, court
deposit or other means without cost to Network Plus); provided, however, that if
any such lien or encumbrance is not so discharged and released within 30 days
after written notice by Network Plus to NEON, then Network Plus may pay or
secure the release or discharge thereof and NEON shall indemnify Network Plus
against all costs and expenses (including reasonable attorney's fees) incurred
in discharging and releasing such lien or encumbrance.

16.2     IMPOSED THROUGH NETWORK PLUS. If NEON becomes subject to any

written nondisturbance and attornment agreement substantially to the effect that
the holder of such security interest or lien acknowledges Network Plus's rights
and interests in and to the Network Plus Fiber Network and the IRU hereunder and
agrees that the same shall not be diminished, disturbed, impaired or interfered
with in any adverse respect by the holder of such security interest or lien,
except to the extent that such holder may succeed to the rights of NEON to
require Network Plus to perform its obligations hereunder.

17.      FORCE MAJEURE. The obligations of the parties under this Agreement are
subject to, and neither party shall be in default under this Agreement due to,
any failure or delay in performance that is caused by strike or other labor
problems; accidents; acts of God; fire; flood; adverse weather conditions;
material or facility shortages or unavailability not resulting from such party's
failure to timely place orders therefor; lack of transportation; the imposition
of any governmental codes, ordinances, laws, rules, regulations or restrictions;
condemnation or the exercise of rights of eminent domain; war or civil disorder;
or any other cause beyond the reasonable control of either party hereto;
provided, however, that the incidence of strikes or other labor unrest shall not

otherwise provided for in this Agreement.

18.      DEFAULT.

18.1     BY NETWORK PLUS. Network Plus shall not be in default under this
Agreement, or in breach of any provision hereof unless and until NEON shall have
given Network Plus written notice of such breach and Network Plus shall have
failed to cure the same within 30 days after receipt of such notice; provided,
however, that where such breach cannot reasonably be cured within such 30 day
period, if Network Plus shall proceed promptly to cure the same and prosecute
such curing with due diligence, the time of curing such breach shall be extended
for such period of time as may be necessary to complete such curing up to a
maximum of 60 additional days. Upon the failure by Network Plus to timely cure
any such breach after notice thereof from NEON, NEON shall have the right, in
its sole discretion, to take such action as it may determine to be necessary to
cure the breach or to terminate this Agreement upon written notice to Network
Plus.

18.2     BY NEON. NEON shall not be in default under this Agreement or in breach

30 days after receipt of such notice; provided however, that where such breach
cannot reasonably be cured within such 30 day period, if NEON shall proceed
promptly to cure the same and prosecute such curing with due diligence, the time
for curing such breach shall be extended for such period of time as may be
necessary to complete such curing. Upon the failure by NEON to timely cure any
such breach after notice thereof from Network Plus, Network Plus shall have the
right in its sole discretion to take such action as it may determine to be
necessary to cure the breach or to terminate this Agreement.

18.3     REMEDIES. No remedy provided for herein is intended to be exclusive,
but each remedy shall be cumulative and in addition to and may be exercised
concurrently with any other remedy available to NEON or Network Plus at law or
in equity.

19.      CONFIDENTIALITY. The Parties executed a Confidentiality Agreement on

EXHIBIT 3.1
SPECIFICATIONS

[**]

ACCEPTANCE TEST PLAN

NEON will conduct the following tests as part of its Acceptance Test Plan:

1.       Non-destructive Attenuation Tests (End-to-End)

2.       Optical Time Reflectometer Tests (OTDR) for each fiber

Fiber acceptance testing will be performed to ensure that the _____ fibers will
operate within the parameters of the Specifications set forth in this Agreement.

         More specifically, fiber acceptance testing will include the following:

3.       Continuity Uniformity Tests:

         All fibers shall be tested bi-directionally at 1310 nm or 1550 run, as
         applicable, with an OTDR, the subsequent traces shall be inspected for
         end-to end continuity and for uniform attenuation. These traces will be
         stored on diskette and will be compatible with laser precision PC-OTDR
         software.

4.       Optical Length:

         The OTDR will be used to determine the end-to-end optical length of the
         cable.

5.       Splice Loss:

         Splice loss will be measured bi-directionally with an OTDR using the
         Splice Loss average method. The average splice loss shall be the
         measurement for splice loss set forth in Exhibit B to this Agreement.

6.       End-to-End Loss:

         Using a light source and a power meter, the bi-directional,
         connector-to-connector attenuation will be measured for each fiber at
         1310 nm and 1550 nm, as applicable. The acceptance average attenuation
         per kilometer on a per span basis shall be the attenuation set forth in
         Exhibit B to this Agreement.

7.       Connector Assemblies




                                      -14-

POWER

1)       NEON will provide (Customer) with all AC and DC power at the NEON Site
         required to operate (Customer)'s equipment, to include the following:

         a)       An emergency backup generator is required. The generator must
                  be permanently installed at the NEON Site. The generator
                  system must be sized to carry the full AC electrical load of
                  the site, including all air conditioning and DC rectifiers.
                  The generator system must be designed and maintained so as to
                  carry the full AC electrical load of the site continuously for
                  seventy-two (72) hours and have auto-transfer switching the
                  capacity.

         b)       A redundant -48V nominal, 100 A DC electrical feed is required
                  at sites. These feeds will terminate at a Battery Distribution
                  Circuit Breaker Board (BDCBB). The DC power plant will be
                  equipped with redundant rectifiers so that the loss of one
                  rectifier will not impede the delivery of (Customer)'s
                  required current ratings. The 100 A redundant feed requires
                  two (2) separate circuits to the BDCBB. Each circuit should be
                  protected by an over-current protection device rated at 100 A.
                  Each feed should be designed with a maximum loop voltage drop
                  of one volt (1 V) at the full 100 A. The BDCBB will be
                  installed in a relay rack separate from other equipment. The
                  BDCBB will be equipped with ten (10) 20 A circuit breakers,
                  ten (10) 30 A circuit breakers and four (4) 50 A breakers. The
                  breakers must be alarmable.

         c)       There will be no point in the DC electrical system past the
                  site main AC disconnect to the BDCBB where AC or DC current
                  must flow through a single over-current protection device.
                  This requires that there must be more than one AC source to
                  the rectifiers and there must be more than one rectifier. If
                  battery disconnects are used there must be more than one
                  battery system.

         d)       The NEON's battery plant will be engineered and maintained so
                  as to provide eight (8) hours reserve time for (Customer)
                  Electronics). This will require the NEON's DC power feeds to
                  be able to provide the full DC current load at a voltage no
                  smaller in magnitude than 43.44V

         to Exhibit H, and/or conduit to the (Customer) Space and NEON will work
         with (Customer) to facilitate construction and/or installation for such
         activities. NEON will not charge any additional charges for the
         additional cable.

3)       (Customer) will have the right to upgrade the NEON Site in the future
         to a POP site. (Customer) will provide notice to NEON of its intent to
         upgrade and will provide information regarding any additional facility
         requirements.

                                  IRU AGREEMENT

         THIS IRU AGREEMENT (this "Agreement") is made and entered into as of
July 17, 1998, by and between QWEST COMMUNICATIONS CORPORATION, a Delaware
corporation ("QWEST") and NETWORK PLUS, INC., a Massachusetts corporation
("NETWORK").

                                    RECITALS

         A.       QWEST has entered into an IRU Fiber Exchange Agreement with a
third party (the "THIRD PARTY") pursuant to which QWEST has been granted an IRU
in certain dark fibers on a route from New York, New York to Boston,
Massachusetts (the "New York - Boston Segment") as more fully described on
Exhibit A attached hereto;

         B.       NETWORK desires to be granted the right to use certain optical
fibers in the New York - Boston Segment; and

         C.       QWEST desires to grant NETWORK a right to use certain fibers
and other rights in regeneration facilities on and along the New York - Boston
Segment;

         Accordingly, in consideration of the mutual promises set forth below,
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereby agree as follows:


                                    ARTICLE 1

                  GRANT OF IRU IN THE NEW YORK - BOSTON SYSTEM

         1.1      Effective as of the date when both the Delivery Date as
defined in Section 4.3 has occurred and the IRU Fee provided for in Section 2.1
has been paid, QWEST hereby grants to NETWORK and NETWORK hereby purchases from
QWEST an exclusive indefeasible right of use ("IRU"), for the purposes described
herein, in four (4) dark fibers, to be specifically identified, in the New York
- - Boston Segment (sometimes referred to herein as the "Segment"), and, to the
extent provided in Article 7, associated Regeneration Facilities, but in any
event excluding any electronic or optronic equipment, for the Term (as defined
in Article 6) and all on the terms and subject to the covenants and conditions
set forth herein (the "IRU"). The Dark Fibers subject to the IRU are referred to
as the "NETWORK Fibers".

                                    ARTICLE 2

                             CONSIDERATION FOR GRANT

         2.1      In consideration of the grant of the IRU hereunder by QWEST to
NETWORK, NETWORK agrees to pay to QWEST an IRU Fee (the "IRU Fee") of $[**]
per route mile as follows and in accordance with the payment schedule set forth
below:

                  (1)      [**]% upon execution of this Agreement
                  (2)      [**]% upon completion of fiber cable placement in 
                           such Segment

                           construction
                  (4)      [**]% upon the Delivery Date for the Segment

                  For purposes of determining the occurrence of the milestones
triggering payment obligations hereunder, completion of fiber cable placement
shall mean the fiber cable is pulled into the conduit, but without splicing.
Completion of the fiber splicing and civil construction shall mean that the
fibers are spliced and ready for testing and civil facilities are ready for the
customer to occupy and install their equipment.

         2.2      In addition to the amounts payable under Section 2.1, NETWORK
shall be responsible to pay directly or reimburse QWEST for the pass-through
expenses required to be paid pursuant to Article 8.

         2.3      All payments to QWEST set forth in this Article 2 shall be
made by wire transfer of immediately available funds to the account or accounts
designated by QWEST. The initial payment shall be due within three (3) days of
execution of the Agreement.


                                    ARTICLE 3

                  CONSTRUCTION OF THE NEW YORK - BOSTON SEGMENT




<PAGE>   2

         3.1      QWEST represents and NETWORK acknowledges that the New York -
Boston Segment is being constructed by the THIRD PARTY. QWEST represents that
the Segment will be constructed in accordance with the construction
specifications set forth in Exhibit B, industry standards and practices,
applicable building construction and safety codes for such construction and
installation, as well as any and all other applicable governmental laws, codes,
ordinances, statutes and regulations, and to perform in accordance with the
manufacturers' specifications set forth in Exhibit C (Fiber Specifications) and
to operate in accordance with Exhibit D (Fiber Cable Splicing, Testing and
Acceptance Procedures). All NETWORK Fibers will be Lucent True Wave. 

         3.2      QWEST represents and warrants that QWEST or the THIRD PARTY 
have the obligation to obtain or have obtained all Required Rights (as defined
in Section 6.1) and other rights, licenses, permits and authorizations as
required to construct the New York - Boston Segment. Upon NETWORK's written
request, QWEST shall make available for inspection by NETWORK, at QWEST's
offices, copies of all information, documents, agreements, reports, permits,
drawings and specifications obtained by QWEST from the THIRD PARTY and
pertaining to this Article 3 that in QWEST's reasonable determination are
material to the grant of the IRU to NETWORK including, without limitation, the
Required Rights to the extent that the terms of each such document or the legal
restrictions applicable to such information or document permits disclosure and
further as may be redacted to protect disclosure of confidential business and
proprietary terms. QWEST represents that any redacted portions of the Required
Rights documents shall not materially affect the rights of NETWORK granted
hereunder.

                                    ARTICLE 4

                    ACCEPTANCE AND TESTING OF NETWORK FIBERS


         4.1      QWEST represents and warrants that the THIRD PARTY will test
all NETWORK Fibers in accordance with the procedures specified in Exhibit D
("Fiber Cable Splicing, Testing and Acceptance Procedures") to verify that the
NETWORK Fibers are installed and operational in accordance with the
specifications described in Exhibit C. As QWEST is provided notice by the THIRD
PARTY, QWEST shall provide NETWORK notice of the date and time of Fiber
Acceptance Testing such that NETWORK shall have the opportunity to have a person
or persons present to observe the Fiber Acceptance Testing. QWEST will provide
NETWORK with copies of all test results obtained from the THIRD PARTY pertaining
to the NETWORK Fibers prior to acceptance.

         4.2      In the event the Fiber Acceptance Testing results show that
the NETWORK Fibers are not installed or operating within the parameters of the
applicable specifications, QWEST shall take or cause the THIRD PARTY to take
such action as shall be reasonably necessary with respect to such portion of the
NETWORK Fibers as are not installed or do not operate within the parameters of
the applicable specifications to bring the installation and operating standards
of such portion of the NETWORK Fibers within such parameters. After taking such
actions, QWEST shall cause the THIRD PARTY to provide a copy of the new test
results and QWEST shall provide a copy to NETWORK within fourteen (14) days of
the conclusion of the Fiber Acceptance Testing. The cycle described above of
testing, taking corrective action and re-testing shall take place as many time
as necessary to ensure that the NETWORK Fibers operate within the parameters of
the applicable specifications.

         4.3      If the Fiber Acceptance Testing results are within the
parameters of the specifications in Exhibit D, NETWORK shall, within seven (7)
days of receipt of the test results, provide QWEST with a written notice
accepting the NETWORK Fibers. If NETWORK fails to accept its Fibers within seven
(7) days of receipt of the Fiber Acceptance Testing results, then NETWORK shall
be deemed to have accepted its Fibers unless it notifies QWEST within seven (7)
days of receipt of the Fiber Acceptance Testing results that such results are
unacceptable. The date of this notice or the date of deemed acceptance of the
NETWORK Fibers shall be the "Acceptance Date". Notwithstanding Acceptance as
provided herein, the parties agree that subject to extensions for delay
described in Article 20, Force Majeure, the date upon which QWEST will grant the
IRU to NETWORK after Acceptance Testing (the "Delivery Date") will be a date
which is mutually agreeable to the parties but in no event later than December
31, 1998. QWEST will use reasonable efforts to make available Dark Fibers for
lease to NETWORK prior to the Delivery Date subject to completion of the Segment
by the THIRD PARTY.

<PAGE>   3

                                  ARTICLE 5

                                DOCUMENTATION


         5.1      Not later than ninety (90) days after the Acceptance Date,
QWEST shall provide NETWORK with the following documentation which shall be
complete, true and correct:

                  (a)      As-built drawings for the Segment in accordance with
the requirements described in Exhibit B.

                  (b)      Technical specifications of the optical fiber cable
and associated splices and other equipment placed in the Segment including test
results.


                                    ARTICLE 6

                                      TERM

         6.1      The term of this Agreement shall begin on the Effective Date
and shall end at the earlier of the end of the economically useful life of the
NETWORK Fibers (the "Term") or subject to the provisions of Article 10, such
time as right of way agreements, including without limitation, rights, licenses,
authorizations, rights of way, and other agreements necessary for the use of
poles, conduit, cable, wire or other physical plant facilities, as well as any
other such rights, licenses, authorizations (including any necessary state,
tribal or federal authorizations such as environmental permits), rights of way
and other agreements necessary for the installation and use of the NETWORK
Fibers (all of which are referred to as the "Required Rights") are no longer
available to QWEST.

         6.2      In the event that NETWORK, at any time, reasonably determines
that the NETWORK Fibers have reached the end of their economically useful life
and desires not to retain the IRU, NETWORK shall have the right to abandon the
IRU by written notice to QWEST. If, at any time during or after the last year of
the Term, NETWORK fails to use any of the NETWORK Fibers for any period of
thirty (30) consecutive days (except to the extent that such non-use is as a
result of any of the events described in Article 20 or as a result of
maintenance, restoration, relocation, or reconfiguration or as a result of the
failure of QWEST to observe and perform the terms of this Agreement), QWEST
shall give notice to NETWORK of proposed abandonment. In the event NETWORK fails
to notify QWEST within sixty (60) days of its intent to continue use of the
Fibers, NETWORK shall be deemed to have determined that the NETWORK Fibers have
reached the end of their economic life and, accordingly, has abandoned the
NETWORK Fibers. Upon any such notice of abandonment or acknowledgement of
abandonment, the Term of this Agreement shall expire and all rights to the New
York - Boston Segment and the use of such Segment shall revert to QWEST without
reimbursement of any fees or other payments previously made with respect
thereto, and from and after such time NETWORK shall have no further rights or
obligations hereunder with respect to such Segment (subject to the provisions of
Articles 12 and 17).

         6.3      It is understood and agreed that the THIRD PARTY must and does
maintain legal title to the entire New York - Boston Segment subject to the IRU
hereunder. Notwithstanding the foregoing, it is understood and agreed as between
the parties that the grant of the IRU hereunder shall be treated for accounting
and federal and all applicable state and local tax purposes as the sale and
purchase of the NETWORK Fibers, and that on or after the Acceptance Date with
respect to the Segment, NETWORK shall be treated as the owner of the NETWORK
Fibers comprising the Segment for such purposes. The parties agree to file their
respective income tax returns, property tax returns, and other returns and
reports for their respective Impositions on such basis and, except as otherwise
required by law, not to take any positions inconsistent therewith. QWEST
represents and warrants that it will not convey any interest, including any
security interest, in the New York to Boston Segment, to any other entity in any
manner which is not fully consistent with, and subordinate to, NETWORK's rights
under this Agreement.


                                    ARTICLE 7

                     NETWORK ACCESS; REGENERATION FACILITIES

         7.1      QWEST shall provide NETWORK with access to the NETWORK Fibers
by a cable stub taken from the system by the THIRD PARTY and delivered to QWEST
at a QWEST designated location or, as mutually agreed to by the parties, in
selected THIRD PARTY POPs at the fiber distribution panel. All connections shall
be performed by QWEST, at NETWORK's sole cost and expense, in accordance with
QWEST's applicable specifications

Exchange Commission. Asterisks denote omissions.



and operating procedures. NETWORK shall pay QWEST's costs for each such
connection within thirty (30) days of the date of NETWORK's receipt of QWEST's
invoice therefor. NETWORK shall have no limitations on the types of electronics
or technologies employed to utilize the NETWORK Fibers, subject to mutually
agreeable safety procedures and so long as such electronics or technologies do
not interfere with the use of or present a risk of damage to any portion of
QWEST's network. QWEST may route in the NETWORK Fibers through QWEST's separate
terminal endlink, POP or Regeneration Facilities at its sole discretion so long
as such routing does not have a material adverse effect on the security, the
safety or NETWORK's use of the NETWORK Fibers hereunder and QWEST is responsible
for all costs and expenses associated therewith.

         7.2      Exhibit E sets forth the sites along the New York to Boston
Segment at which regeneration facilities currently are located or are to be
installed in accordance with the Specifications set forth on Exhibit F which
NETWORK desires to share with QWEST (collectively, the "Regeneration
Facilities"). Subject to (a) the availability of adequate and sufficient
Required Rights, space, power, and right-of-way access, and (b) the receipt of
all requisite permits, approvals and authorizations, available to NETWORK, QWEST
will make space available for up to one rack in certain regeneration facilities
and up to two racks in certain POPs available to NETWORK on a shared basis for a
cost per facility of $[**] per rack. All shared Regeneration Facilities shall
be subject to the provisions of this Agreement, and in particular Section 8.2
with respect to sharing of operating costs thereof.


                                    ARTICLE 8

                                   OPERATIONS

         8.1      Each party shall have full and complete control and
responsibility for determining any network and service configurations or
designs, routing configurations, regrooming, rearrangement or consolidation of
channels or circuits and all related functions with regard to the use of that
party's Dark Fiber.

         8.2      NETWORK shall reimburse QWEST for NETWORK's proportionate
share of all operating costs incurred by QWEST in connection with the
Regeneration Facilities provided pursuant to Section 7.2, including its
proportionate share of any monthly lease costs for any such facilities and/or
underlying property that QWEST leases (including, to the extent included in such
lease costs, base rent, maintenance, insurance, security and taxes), maintenance
of such facilities, and all power and utility fees and charges. NETWORK's
proportionate share of such operating costs, including a proportionate share of
common area costs, shall be the ratio that the floor space provided to NETWORK
in any such facility (including a proportionate share of the common area) bears
to (1) in the case of lease costs, the total space in such facility, and (2) in
the case of all other costs (including common area costs), the total utilized
space in such facility. QWEST shall submit invoices to NETWORK on an annual
basis for NETWORK's prorata share of such operating costs during the preceding
twelve months. QWEST will operate the Regeneration Facilities in a commercially
reasonable manner. NETWORK's reimbursement obligations for insurance and taxes
pursuant to this Section 8.2 shall in no event be duplicative of NETWORK's
payment obligations for insurance or taxes, respectively, as provided in Article
15 hereof, and in no event shall QWEST be relieved of its payment obligations
for insurance costs or taxes, respectively.

         8.3      NETWORK acknowledges and agrees that, except as expressly
provided in Section 7.2, QWEST is not supplying nor is QWEST obligated to supply
to NETWORK any optronics or electronics or optical or electrical equipment or
other facilities, including, without limitation, generators, batteries, air
conditioners, fire protection and monitoring and testing equipment, all of which
are the sole responsibility of NETWORK, nor is QWEST responsible for performing
any work other than as specified in this Agreement.


                                    ARTICLE 9

             MAINTENANCE AND REPAIR OF THE NEW YORK - BOSTON SEGMENT

         9.1      From and after the Acceptance Date the maintenance of the New
York - Boston Segment shall be provided in accordance with the maintenance
requirements and procedures set forth in Exhibit G hereto.

                                   ARTICLE 10

                      PERMITS, REQUIRED RIGHTS; RELOCATIONS

         10.1      QWEST represents and warrants that on or before the Delivery
Date with respect to the Segment to be delivered hereunder, the THIRD PARTY is
responsible to obtain any Required Rights and, thereafter, to use commercially
reasonable efforts to cause the Required Rights to remain in effect for a
minimum term of twenty years (the "Minimum Period"). QWEST agrees to exercise
all commercially reasonable efforts to enforce its rights to require Specific
Performance of the THIRD PARTY's obligations and other remedies available to
QWEST under its Agreement with the THIRD PARTY to keep the Required Rights in
force for the Minimum Period. QWEST acknowledges that its failure to exercise
such efforts will cause NETWORK irreparable harm, and that accordingly, NETWORK
shall have the right to obtain specific performance of QWEST's obligations set
forth in the preceding sentence.

         10.2      Upon the expiration or termination of any Required Right that
is necessary in order to grant, continue or maintain the IRU granted hereunder
in accordance with the terms and conditions hereof, and so long as QWEST shall
have fully observed and performed its obligations under this Article 10 with
respect thereto, the Term of the IRU hereunder with respect to the Segment, or
any portion of the Segment affected by such expiration or termination of a
Required Right, shall automatically expire upon such expiration or termination
of the Required Right.

         10.3      If, after the Acceptance Date with respect to the Segment,
(i) the THIRD PARTY or QWEST reasonable determines, or (ii) the THIRD PARTY or
QWEST is required by a third party with legal authority to so require
(including, without limitation, the grantor of a Required Right), or (iii)
NETWORK agrees to relocate any portion of the Segment, including any of the
facilities used or required in providing the IRU in such Segment hereunder,
QWEST or the THIRD PARTY, as applicable, shall proceed with such relocation, and
shall have the right, in good faith, to reasonably determine the extent of, the
timing of, and methods to be used for such relocation; PROVIDED THAT (a) any
such relocation shall be constructed and tested in accordance with the
specifications and drawings set forth in Exhibits B and C, and incorporate fiber
meeting the specifications set forth in Exhibit D and (b) if the relocation is
pursuant to (i) above, or subject to Article 20, to (ii) above, it shall not
adversely affect the operations, performance, connection points with NETWORK's
network or endpoints of the Segment.

         10.4      Unless QWEST is reimbursed by a third party (which does not
have an interest in the fibers in the cable) NETWORK shall reimburse QWEST for
its proportionate share of all costs of such relocation, including without
limitation conduit relocation, fiber acquisition, splicing and testing, of the
portion of the Segment based on the proportion of the NETWORK Fibers to the
total fibers in the cable.


                                   ARTICLE 11

                        USE OF NEW YORK - BOSTON SEGMENT

         11.1     The requirements, restrictions, and/or limitations upon
NETWORK's right to use the NETWORK Fibers as provided and permitted under this
Agreement imposed under, and associated safety, operational and other rules and
regulations imposed in connection with, the Required Rights are referred to
collectively as the "Required Rights Requirements." NETWORK acknowledges and
agrees that it is taking its IRU on an "as is, where is" basis and that it is
receiving the interests in such IRU Fibers as set forth in this Agreement only
to the extent such interests are held by the conveying party.

         11.2     Each of the parties represents, warrants and covenants that it
will use its fibers in compliance with and subject to the Required Rights
Requirements (to the extent provided by the THIRD PARTY and known to QWEST and
NETWORK) and all applicable government codes, ordinances, laws, rules and
regulations.

         11.3     The IRU granted hereunder shall include the right at NETWORK's
cost to install additional equipment, or replaces existing equipment, in the
facility space provided to NETWORK pursuant to Article 7, subject to the
provisions of Article 7 and the Required Rights Requirements.

         11.4     QWEST agrees and acknowledges that it has no right to use the
NETWORK Fibers during the Term hereof, and that, from and after the effective
date of the


                                       -5-


<PAGE>   6


Agreement, QWEST shall keep the NETWORK Fibers and NETWORK's IRU granted
hereunder free from (a) any liens of any third party attributable to QWEST, and
(b) any rights or claims of any third party attributable to QWEST, as and to the
extent required pursuant to Article 10 hereof. As provided in the previous
sentence, QWEST shall obtain from any entity in favor of which QWEST in its
discretion shall have granted after the date hereof a security interest or lien
on all or part of the Segment a written nondisturbance agreement substantially
to the effect that such lienholder acknowledges NETWORK's rights and interests
in and to the NETWORK Fibers and the IRU hereunder and agrees that the same
shall not be diminished, disturbed, impaired or interfered with in any adverse
respect by such lienholder. QWEST represents that this same or similar provision
is in all other agreements under which QWEST has granted IRUs in the New York to
Boston Segment.

         11.5     Subject to the provisions of Article 22 and this Article 11,
NETWORK may use the NETWORK Fibers and the IRU for any lawful telecommunications
purpose. NETWORK agrees and acknowledges that it has no right to use any of the
fibers, other than the NETWORK Fibers, included in the cable or otherwise
incorporated in the New York - Boston Segment, and that NETWORK shall keep any
and all of the New York - Boston Segment, other than the IRU granted to NETWORK
in the NETWORK Fibers free from any liens, rights or claims of any third party
attributable to NETWORK.

         11.6     NETWORK and QWEST shall promptly notify each other of any
matters pertaining to, or the occurrence (or impending occurrence) of any event
which would be reasonably likely to give rise to any damage or impending damage
to or loss of the New York - Boston Segment that are known to such party.

         11.7     NETWORK shall not use the NETWORK Fibers in a way which
physically interferes in any way with or adversely affects the use of the fibers
or cable of any other person using the New York - Boston Segment. QWEST shall
not use any other fibers in the New York - Boston Segment in a way which
physically interferes with or adversely affects the use of the NETWORK Fibers.
QWEST represents that this same or similar provision is in all other agreements
under which QWEST has granted IRUs in the New York to Boston Segment. 

         11.8     NETWORK and QWEST each agree to cooperate with and support the
other in complying with any requirements applicable to their respective rights
and obligations hereunder by any governmental or regulatory agency or authority.


                                   ARTICLE 12

                                 INDEMNIFICATION

         12.1     Subject to the provisions of Articles 13 and 18, QWEST hereby
agrees to indemnify, defend, protect and hold harmless NETWORK and its
employees, officers and directors, from and against, and assumes liability for:

                  (a)      Any injury, loss or damage to any person (including
NETWORK), tangible or intangible property or facilities of any person or entity
(including reasonable attorneys' fees and costs) to the extent arising out of or
resulting from the acts or omissions, negligent or otherwise, of QWEST, its
officers, employees, servants, affiliates, agents, contractors, or licensees
arising out of or in connection with a default (other than a default caused by a
failure of NETWORK to perform or comply with its obligations hereunder) by QWEST
in the performance of its obligations or breach of its representations under
this Agreement; and

                  (b)      Any claims, liabilities or damages, including
reasonable attorneys' fees and costs, arising out of any violation by QWEST of
any regulation, rule, statue or court order of any local, state or federal
governmental agency, court or body in connection with the performance of its
obligations under this Agreement.

         12.2     Subject to the provisions of Articles 13 and 18, NETWORK
hereby agrees to indemnify, defend, protect and hold harmless QWEST, and its
employees, officers and directors, from and against, and assumes liability for:

                  (a)      Any injury, loss or damage to any person (including
QWEST), tangible or intangible property or facilities of any person or entity
(including reasonable attorneys' fees and costs) to the extent arising out of or

performance of its obligations or breach of its representations under this
Agreement; and

                  (b)      Any claims, liabilities or damages, including
reasonable attorneys' fees and costs, arising out of any violation by NETWORK of
any regulation, rule, statue or court order of any local, state or federal
governmental agency, court or body in connection with its use of the IRU and/or
the NETWORK Fibers and Associated Property hereunder. 

         12.3     The parties hereby expressly recognize and agree that each
party's said obligation to indemnify, defend, protect and save the other
harmless is not a material obligation to the continuing performance of the
parties' other obligations, if any, hereunder. In the event that a party shall
fail for any reason to so indemnify, defend, protect and save the other
harmless, the injured party hereby expressly recognizes that its sole remedy in
such event shall be to seek a remedy under Article 21 against the other party
for its damages as a result of the other party's failure to indemnify, defend,
protect and save harmless. The obligations of the parties under this Article 12
shall survive the expiration or termination of this Agreement.

         12.4     Nothing contained herein shall operate as a limitation on the
right of either party hereto to bring an action for damages against any third
party, including indirect, special or consequential damages, based on any acts
or omissions of such third party as such acts or omissions may affect the
operation or use of the NETWORK Fibers or the QWEST network, except as may be
limited by Required Rights Requirements; PROVIDED, HOWEVER, that each party
hereto shall assign such rights or claims, execute such documents and do
whatever else may be reasonably necessary to enable the other party to pursue
any such action against such third party.


                                   ARTICLE 13

                             LIMITATION OF LIABILITY

         13.1     Notwithstanding any provision of this Agreement to the
contrary, neither party shall be liable to the other party for any special,
incidental, indirect, punitive or consequential damages, whether foreseeable or
not, arising out of, or in connection with such party's failure to perform its
respective obligations or breach of its respective representations hereunder,
including, but not limited to, damage or loss of property or equipment, loss of
profits or revenue, cost of capital, (whether arising out of transmission
interruptions or problems, any interruption or degradation of service or
otherwise), or claims of customers, in each case whether occasioned by any
construction, reconstruction, relocation, repair or maintenance performed by, or
failed to be performed by, the other party or any other cause whatsoever,
including breach of contract, breach of warranty, negligence, or strict
liability, all claims with respect to which such special, incidental, indirect,
punitive or consequential damages are hereby specifically waived.


                                   ARTICLE 14

                                    INSURANCE

         14.1     Following the Delivery Date with respect to the Segment, and
throughout the Term of the IRU with respect to the Segment, each party shall
procure and maintain in force, at its own expense:

                  (a)      not less than $[**] combined single limit
liability insurance, on an occurrence basis, for personal injury and property
damage, including, without limitation, injury or damage arising from the
operation of vehicles or equipment and liability for completed operations;

                  (b)      workers' compensation insurance in amounts required
by applicable law and employers' liability insurance with a limit of at least
$[**] per occurrence; and

                  (c)      automobile liability insurance covering death or
injury to any person or persons, or damage to property arising from the
operation of vehicles or equipment, with limits of not less than $[**] per
occurrence; and

         14.2     Both parties expressly acknowledge that a party shall be
deemed to be in compliance with the provisions of this Article 14 if it
maintains an approved self-insurance program providing for a retention of up to
$[**]. If either party



                                       -7-


<PAGE>   8


provides any of the foregoing coverages on a claims-made basis, such policy or
policies shall be for at least a three-year extended reporting or discovery
period. Unless otherwise agreed, NETWORK's and QWEST's insurance policies shall
be obtained and maintained with companies rated "A" or better by Best's Key
Rating Guide and each party shall provide the other with an insurance
certificate confirming compliance with this requirement for each policy
providing such required coverage.

         14.3     In the event either party fails to obtain the required
insurance and a claim is made or suffered, such party shall indemnify and hold
harmless the other party from any and all claims for which the required
insurance would have provided coverage. Further, in the event of any such
failure which continues after seven (7) days' written notice thereof by the
other party, such other party may, but shall not be obligated to, obtain such
insurance and will have the right to be reimbursed for the cost of such
insurance by the party failing to obtain such insurance.

         14.4     In the event coverage is denied or reimbursement of a properly
presented claim is disputed by the carrier for insurance provided above, the
party carrying such coverage shall make good-faith efforts to pursue such claim
with its carrier.

         14.5     Both parties shall obtain from their insurance companies
providing the coverages required by this Agreement the permission of such
insurers to allow that party to waive all rights of subrogation and each party
does hereby waive all rights of said insurance companies to subrogation against
the other, its parent corporation, affiliates, subsidiaries, assignees,
officers, directors, and employees or any other party entitled to indemnify
under this Agreement.


                                   ARTICLE 15

                 TAXES, FEES AND OTHER GOVERNMENTAL IMPOSITIONS

         15.1     The parties acknowledge and agree that it is their mutual
objective and intent to (a) minimize, to the extent feasible, the aggregate
Impositions payable with respect to the New York - Boston Segment and (b) share
such Impositions according to their respective interests in the New York -
Boston Segment, and that they will cooperate with each other and coordinate
their mutual efforts to achieve such objectives in accordance with the
provisions of this Article 15. It is understood and agreed as between the
parties that the grant of the IRU in the NETWORK Fibers shall be treated for
accounting and federal and all applicable state and local tax purposes as the
sale and purchase of the NETWORK Fibers and that on or after the Acceptance
Date, NETWORK shall be treated as the owner of the NETWORK Fibers for such
purposes. The parties agree to file their respective income tax returns,
property tax returns, and other returns and reports for their respective
Impositions on such basis and except as otherwise required by law, not to take
any positions inconsistent therewith.

                                   ARTICLE 17

                                 CONFIDENTIALITY

         17.1     (a)      QWEST and NETWORK hereby agree that if either party
provides (or, prior to the execution hereof, has provided) confidential or
proprietary information to the other party ("Proprietary Information"), such
Proprietary Information shall be held in confidence, and the receiving party
shall afford such Proprietary Information the same care and protection as it
affords generally to its own confidential and proprietary information (which in
any case shall be not less than reasonable care) in order to avoid disclosure to
or unauthorized use by any third party.

                  (b)      As used herein, Proprietary Information shall mean
any and all technical or business information furnished, in whatever form or
medium, or disclosed by QWEST to NETWORK including, but not limited to, product
or service specifications, prototypes, computer programs, models, drawings,
marketing plans, financial data, and personnel statistics. In addition, the
parties acknowledge and agree that this Agreement, including all of the terms,
conditions and provisions hereof, all drafts hereof, and all information
disclosed by either party to the other in connection with or pursuant to this
Agreement constitutes Proprietary Information.

                  (c)      All Proprietary Information, unless otherwise
specified in writing, shall remain the property of the disclosing party, shall
be used by the receiving party only for the intended purpose of performing its
obligations under this Agreement, and such written Proprietary Information,
including all copies thereof, shall be returned to the disclosing party or
destroyed after the receiving party's need for it has expired or upon the
request of the disclosing party. Proprietary Information shall not be reproduced
except to the extent necessary to accomplish the purpose and intent of this
Agreement, or as otherwise may be permitted in writing by the disclosing party.

         17.2     The foregoing provisions of Section 17.1 shall not apply to
any Proprietary Information which (a) becomes publicly available other than
through the recipient; (b) is required to be disclosed by a governmental or
judicial law, order, rule or regulation; (c) is independently developed by the
disclosing party; (d) becomes available to the disclosing party without
restriction from a third party not subject to an obligation to protect such
Proprietary Information; or (e) to the extent (and only to the extent) that
disclosure is reasonably necessary in connection with the settlement of any
dispute or enforcement of either party's rights under this Agreement in
accordance with the provisions of this Agreement, in which case appropriate
protective measures shall be taken to preserve the confidentiality of such
Proprietary Information as fully as possible within the confines of such
settlement or enforcement process. If any Proprietary Information is required to
be disclosed pursuant to the foregoing clause (b), the party required to make
such disclosure shall promptly inform the other party of the requirements of
such disclosure and shall cooperate with the other party in seeking a protective
order or similar relief.

Exchange Commission. Asterisks denote omissions.



         17.3     Neither party shall publish or use any advertising, sales
promotions, or other publicity materials that use the other party's logo,
trademarks, or service marks without the prior written approval of the other
party.

         17.4     Each party shall have the right to review and approve any
publicity material, press releases, or other public statements by the other that

statements without the prior written approval of the other party.

party to use any of the other party's brands, marks or logos without prior
written approval of the other party.

         17.6     Nothing herein shall be construed as granting any right or
license under any copyrights, inventions, or patents now or hereafter owned or
controlled by QWEST.

         17.7     Notwithstanding Sections 17.1 and 17.2 of this Article, either
party may disclose Proprietary Information to its employees, agents, and legal,
financial, and accounting advisors and providers (including its lenders and
other financiers) to the extent necessary or appropriate in connection with the
negotiation and/or performance of this Agreement or its obtaining of financing,
PROVIDED THAT each such party is notified of the confidential and proprietary
nature of such Proprietary Information and is subject to or agrees to be bound
by similar restrictions on its use and disclosure.

         17.8     The provisions of this Article shall survive expiration or
termination of this Agreement for a period of three years thereafter.


                                   ARTICLE 18

                                     DEFAULT

         18.1     With respect to all payments required to be made by NETWORK
hereunder, including, without limitation, payment of the IRU Fee and all other
amounts payable by NETWORK hereunder, if NETWORK fails to make a payment by the
date due and payable hereunder, from and after such date, (a) such unpaid amount
shall bear accrued interest compounded monthly until paid at an annual rate
equal to one hundred fifty percent ([**]%) of the prime rate of interest
published by the Wall Street Journal the date any such payment is due or, if
lower, the highest percentage allowed by law and (b) if such payment is due with
respect to the Segment on or prior to the Acceptance Date of the Segment, the
Estimated Delivery Date for the Segment shall be extended by a number of days
equal to the number of days that elapse from the date such payment is due until
paid. In the event any amount or amounts due and payable hereunder remain unpaid
for a period of thirty (30) days after written notice from QWEST to NETWORK,
then QWEST may, in its sole and absolute discretion and in addition to its other
rights and remedies hereunder, terminate any and all of its obligations
hereunder with respect to the Segment, and to apply any and all amounts
previously paid by NETWORK hereunder with respect to the Segment toward the
payment of any other amounts then or thereafter payable by NETWORK hereunder.

                  With respect to all of its other obligations hereunder, if
NETWORK fails to perform a nonpayment obligation and such failure shall continue
for a period of thirty (30) days after QWEST shall have given NETWORK written
notice of such failure, NETWORK shall be in default hereunder unless NETWORK
shall have cured such failure or such failure is otherwise waived in writing by
QWEST within such thirty (30) days; PROVIDED, HOWEVER, that where such failure
cannot reasonably be cured within such 30- day period, if NETWORK shall proceed
promptly to cure the same and prosecute such cure with due diligence, the time
for curing such failure shall be extended for such period of time as may be
necessary to complete such cure; and PROVIDED FURTHER that if NETWORK certifies
in good faith to QWEST in writing that a nonpayment failure has been cured, such
failure shall be deemed to be cured unless QWEST otherwise notifies NETWORK in
writing within fifteen (15) days of receipt of such notice from NETWORK.

                  NETWORK shall be in default hereunder (a) automatically upon
the making by NETWORK or Parent of a general assignment for the benefit of its
creditors, the filing by NETWORK or Parent of a voluntary petition in bankruptcy
or the filing by NETWORK or Parent of any petition or answer seeking, consenting
to, or acquiescing in reorganization, arrangement, adjustment, composition,
liquidation, dissolution, or




                                      -10-

similar relief; or (b) one hundred twenty (120) days after the filing of an
involuntary petition in bankruptcy or other insolvency protection against
NETWORK which is not dismissed within such one hundred twenty (120) days.

                  Except as otherwise provided in this Section 18.1, upon any
default by NETWORK, after written notice thereof from QWEST, QWEST may (a) take
such action as it determines, in its sole discretion, to be necessary to correct
the default and, subject to Section 13.1, recover from NETWORK its reasonable
costs incurred in correcting such default, and (b) pursue any legal remedies it
may have under applicable law or principles of equity relating to such default,
including specific performance.

         18.2     With respect to QWEST's obligations hereunder, in the event
that QWEST shall fail to perform an obligation and such failure shall continue
for a period of thirty (30) days after NETWORK shall have given QWEST written
notice of such failure, QWEST shall be in default hereunder unless QWEST shall
have cured such failure or such failure is otherwise waived in writing by
NETWORK within such thirty (30) days; PROVIDED HOWEVER, that where such failure
cannot reasonably be cured within such 30-day period, or if QWEST's failure is
a failure of the THIRD PARTY to complete the construction, installation and
satisfactory Fiber Acceptance Testing by the Estimated Delivery Date for the
Segment pursuant to Section 4.3, or QWEST's failure to deliver an IRU in the
fibers pursuant to RECITAL A, if QWEST shall proceed promptly to cure the same
and prosecute such cure with due diligence, or with respect to the Estimated
Delivery Date, shall proceed to diligently complete or to cause the THIRD PARTY
to complete the construction, installation and testing, the time for curing such
failure, including a failure to meet an Estimated Delivery Date, shall be
extended for such period of time as may be necessary to complete such cure or
such construction, installation and testing; and PROVIDED FURTHER, that if QWEST
certifies in good faith to NETWORK in writing that failure has been cured, such
failure shall be deemed to be cured unless NETWORK otherwise notifies QWEST in
writing within fifteen (15) days of receipt of such notice from QWEST.
Notwithstanding the foregoing provisions of this paragraph, in the event a force
majeure event or occurrence described in Article 20 or any other event causes an
extension of the Estimated Delivery Date and such event or occurrence has not
been terminated, avoided or resolved by the date that is six (6) months
following the Estimated Delivery Date, NETWORK may elect, in its sole
discretion, by written notice to QWEST, to terminate this Agreement and recover
from QWEST the amount of the IRU Fee previously paid by NETWORK hereunder with
respect to the Segment. Upon any such election and payment, neither party shall
have any further rights or obligations.

                  QWEST shall be in default hereunder (a) automatically upon the
making by QWEST of a general assignment for the benefit of its creditors, the
filing by QWEST of a voluntary petition in bankruptcy or the filing by QWEST of
any petition or answer seeking, consenting to, or acquiescing in reorganization,
arrangement, adjustment, composition, liquidation, dissolution, or similar
relief, or (b) one hundred twenty (120) days after the involuntary filing of a
petition in bankruptcy or other insolvency protection against QWEST which is not
dismissed within such 120-day period.

                  Except as otherwise provided in this Section 18.02, upon any
default by QWEST, after notice thereof from NETWORK, NETWORK may (a) take such
action as it determines, in its sole discretion, to be necessary to correct the
default, and, subject to Section 13.01, recover from QWEST its reasonable costs
in correcting such default, and (b) pursue any legal remedies it may have under
applicable law or principles of equity relating to such default including
specific performance.


                                   ARTICLE 19

                                   TERMINATION

         19.1     This Agreement automatically shall terminate with respect to a
Segment upon the expiration or termination of the Term of the IRU respecting the
Segment pursuant to Article 6 or Section 17.02 hereof.

         19.2     Upon the expiration or termination of this Agreement, the IRU
shall immediately terminate and all rights of NETWORK to use the Segment, the
NETWORK Fibers, the associated property or any part thereof relating to the
Segment, shall cease and QWEST shall owe NETWORK no additional duties or
consideration with respect to the Segment. Promptly thereupon, NETWORK shall
remove all of NETWORK's electronics, equipment, and other NETWORK property from
such Segment and any related




                                      -11-


<PAGE>   12


QWEST facilities at its sole cost, under QWEST's supervision (which supervision
shall be without cost to NETWORK).

         19.3     Notwithstanding the foregoing, no termination or expiration of
this Agreement shall affect the rights or obligations of any party hereto (a)
with respect to any then existing defaults or the obligation to make any payment
hereunder for services rendered prior to the date of termination or expiration,
(b) with respect to any accrued liability for taxes pursuant to Article 15, or
(c) pursuant to Article 12, Article 13, or Article 17 herein, which shall
survive the expiration or termination hereof.


                                   ARTICLE 20

                                  FORCE MAJEURE

         20.1     Neither party shall be in default under this Agreement if and
to the extent that any failure or delay in such party's performance of one or
more of its obligations hereunder is caused by any of the following conditions,
and such party's performance of such obligation or obligations shall be excused
and extended for and during the period of any such delay: act of God; fire;
flood; fiber, Cable, or other material failures, shortages or unavailability or
other delay in deliver not resulting from the responsible party's failure to
timely place orders therefor (it being expressly acknowledged that the Cable
that is being acquired for and installed in the New York - Boston Segment and
that will include the NETWORK Fibers must include higher fiber counts than that
necessary solely for the NETWORK Fibers in order to permit completion of the
entire New York - Boston Segment); lack of or delay in transportation;
government codes, ordinances, laws, rules, regulations or restrictions; war or
civil disorder; strikes or other labor disputes; failure of a third party to
grant or recognize the Required Rights (provided that QWEST has made timely and
reasonable commercial efforts to obtain the same), or any other cause beyond the
reasonable control of such party. The party claiming relief under this Article
shall notify the other in writing of the existence of the event relied on and
the cessation or termination of said event, and the party claiming relief shall
exercise reasonable commercial efforts to minimize the time of any such delay.


                                   ARTICLE 21

                               DISPUTE RESOLUTION

         21.1     Except as provided in Sections 18.1 and 18.2, if the parties
are unable to resolve any disagreement or dispute arising under or related to
this Agreement, including without limitation, the failure to agree upon any item
requiring a mutual agreement of the parties hereunder, they shall resolve the
disagreement or dispute by arbitration as prescribed in this Section. The
Federal Arbitration Act, 9 U.S.C. Sections 1-15, not state law, shall govern the
arbitrability of all claims.

         21.2     A single arbitrator engaged in the practice of law who is
knowledgeable about the subject matter of this Agreement shall conduct the
arbitration under the then current rules of the American Arbitration Association
(the "AAA"). The arbitrator shall be selected in accordance with AAA procedures
from a list of qualified people maintained by the AAA. The arbitration shall be
conducted in the regional AAA office in Chicago, Illinois, and all expedited
procedures prescribed by the AAA rules shall apply.

         21.3     There shall be no discovery other than the exchange of
information which is provided to the arbitrator by the parties. The arbitrator
shall have authority only to award compensatory damages and shall not have
authority to award punitive damages, other noncompensatory damages or any other
form of relief; the parties hereby waive all rights to any claims for relief
other than compensatory damages. The arbitrators' fees and other costs of the
arbitration shall be borne by the party against whom the award is rendered,
except as the arbitrator may otherwise provide in a written opinion. The
arbitrator shall apply the substantive laws of the State of New York and the
terms and conditions of this Agreement, and shall make written findings of fact
and conclusions of law in support of the award.

         21.4     If any party files a judicial or administrative action
asserting claims subject to arbitration as prescribed herein, and another party
successfully stays such action or compels arbitration of said claims, the party
filing said action shall pay



                                      -12-

the other party's costs and expenses incurred in seeking such stay or compelling
arbitration, including reasonable attorneys' fees.


                                   ARTICLE 22

                       ASSIGNMENT AND DARK FIBER TRANSFERS

         22.1     Except as provided below, QWEST shall not assign, encumber or
otherwise transfer this Agreement or all or any portion of its rights or
obligations hereunder to any other party without the prior written consent of
NETWORK, which consent will not be unreasonably withheld or delayed.
Notwithstanding the foregoing, QWEST shall have the right, without NETWORK's
consent, to (a) subcontract any of its construction or maintenance obligations
hereunder, or (b) assign or otherwise transfer this Agreement in whole or in
part (1) as collateral to any institutional lender to QWEST (or institutional
lender to any permitted transferee or assignee of QWEST) subject to the prior
rights and obligations of the parties hereunder, (2) to any parent, subsidiary
or affiliate of QWEST, (3) to any person, firm or corporation which shall
control, be under the control of or be under common control with QWEST, or (4)
any corporation or other entity into which QWEST may be merged or consolidated
or which purchases all or substantially all of the stock or assets of QWEST;
PROVIDED THAT the assignee or transferee in any such circumstance shall continue
to be subject to all of the provisions of this Agreement, including without
limitation, this Section 22.1 (except that any lender referred to in clause
(b)(1) above shall not incur any obligations under this Agreement nor shall it
be restricted from exercising any right of enforcement or foreclosure with
respect to any related security interest or lien, so long as the purchaser in
foreclosure is subject to the provisions of this Agreement, including, without
limitation, this Section 22.1); and PROVIDED FURTHER THAT promptly following any
such assignment or transfer, QWEST shall give NETWORK written notice identifying
the assignee or transferee. In the event of any permitted partial assignment of
any rights hereunder, QWEST shall remain the sole point of contact with NETWORK.

Section 22.2 and the following Section 22.3); and PROVIDED FURTHER THAT in any
of circumstances described in clauses (b), (c) or (d) all of the payment
obligations of NETWORK hereunder for the remainder of the Term shall be paid in

respect to any NETWORK Fibers comprising the Segment in a manner designed or
intended to circumvent the foregoing limitations.

         22.4     This Agreement and each of the parties' respective rights and
obligations under this Agreement, shall be binding upon and shall inure to the

                 REPRESENTATIONS, WARRANTIES AND ACKNOWLEDGMENTS

         23.1     Each party represents and warrants that:

                  (a)      it has the full right and authority to enter into,
execute, deliver and perform its obligations under this Agreement;

                  (b)      this Agreement constitutes a legal, valid and binding
obligation enforceable against such party in accordance with its terms, subject
to bankruptcy, insolvency, creditors' rights and general equitable principles;
and

                  (c)      its execution of and performance under this Agreement
shall not violate any applicable existing regulations, rules, statues or court
orders of any local, state or federal government agency, court or body.

         23.2     QWEST represents and warrants that the terms of its Agreement
with the THIRD PARTY specifically provide that QWEST may grant an IRU in its
dark fibers to a third party and, further, that the terms of the Required Rights
documents do not preclude the assignment of its fibers to NETWORK.

         23.3     QWEST represents and warrants that the Segment shall be
constructed by the THIRD PARTY substantially and in all material respects in
accordance with the specifications set forth in Exhibit B hereto.

         23.4     EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT QWEST MAKES NO
WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO THE NETWORK FIBERS OR THE SEGMENTS
DELIVERABLE HEREUNDER, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR
PARTICULAR PURPOSE, AND ALL SUCH WARRANTIES ARE HEREBY EXPRESSLY DISCLAIMED.

         23.5     The parties acknowledge and agree that on and after the
Acceptance Date NETWORK's sole rights and remedies (as between the parties
hereto) with respect to any defect in or failure of the NETWORK Fibers (other
than any defect or failure caused by the willful or negligent act or omission of
QWEST) to perform in accordance with the applicable vendor's or manufacturer's
specifications with respect to the NETWORK Fibers shall be limited to the
particular vendor's or manufacturer's warranty with respect thereto, which
warranty, to the extent permitted by the terms thereof, shall be assigned to
NETWORK upon its request. In the event any maintenance or repairs to the New
York - Boston Segment are required as a result of a breach of any warranty made
by any manufacturers, contractors or vendors, unless NETWORK shall elect to
pursue such remedies itself, QWEST shall pursue all remedies against such
manufacturers, contractors or vendors on behalf of NETWORK, and QWEST shall
reimburse NETWORK's costs for any maintenance NETWORK has incurred as a result
of any such breach of warranty to the extent the manufacturer, contractor or
vendor has paid such costs.

                                     GENERAL

         24.1     WAIVER. The failure of either party hereto to enforce any of
the provisions of this Agreement, or the waiver thereof in any instance, shall
not be construed as a general waiver or relinquishment on its part of any such
provision, but the same shall nevertheless be and remain in full force and
effect.

         24.2     GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the domestic laws of the State of New York, without
reference to its choice of law principles. Subject to Article 21 hereof, any
litigation based hereon,

or arising out of or in connection with a default by either party in the
performance of its obligations hereunder, shall be brought and maintained
exclusively in the courts of the State of New York, or in the United States
District Court in New York, and each party hereby irrevocable submits to the
jurisdiction of such courts for the purpose of any such litigation and
irrevocably agrees to be bound by any judgment rendered thereby in connection
with such litigation.

         24.3     RULES OF CONSTRUCTION. The captions or headings in this
Agreement are strictly for convenience and shall not be considered in
interpreting this Agreement or as amplifying or limiting any of its content.
Words in this Agreement which import the singular connotation shall be

may require.

                  (a)      Unless expressly defined herein, words having well
known technical or trade meanings shall be so construed. All listing of items
shall not be taken to be exclusive, but shall include other items, whether
similar or dissimilar to those listed, as the context reasonably requires.

                  (b)      Except as set forth to the contrary herein, any right
or remedy of NETWORK or QWEST shall be cumulative and without prejudice to any
other right or remedy, whether contained herein or not.

jointly drafted by the parties.

                  (d)      All actions, activities, consents, approvals and

reasonable and timely manner. Except as specifically set forth herein, for the
purpose of this Agreement the standards and practices of performance within the
telecommunications industry in the relevant market shall be the measure of a
party's performance.

         24.4     ENTIRE AGREEMENT. This Agreement constitutes the entire and
final agreement and understanding between the parties with respect to the
subject matter hereof and supersedes all prior agreements relating to the
subject matter hereof, which are of no further force or effect. The Exhibits
referred to herein are integral parts hereof and are hereby made a part of this
Agreement. To the extent that any of the provisions of any Exhibit hereto are
inconsistent with the express terms of this Agreement, the terms of this
Agreement shall prevail. This Agreement may only be modified or supplemented by
an instrument in writing executed by a duly authorized representative of each
party and delivered to the party relying on the writing.

         24.5     NO PERSONAL LIABILITY. Each action or claim against any party
arising under or relating to this Agreement shall be made only against such
party as a corporation, and any liability relating thereto shall be enforceable
only against the corporate assets of such party. No party shall seek to pierce
the corporate veil or otherwise seek to impose any liability relating to, or
arising from, this Agreement against any shareholder, employee, officer or
director of the other party. Each of such persons is an intended beneficiary of
the mutual promises set forth in this Article and shall be entitled to enforce
the obligations of this Article.

         24.6     RELATIONSHIP OF THE PARTIES. The relationship between NETWORK
and QWEST shall not be that of partners, agents, or joint venturers for one
another, and nothing contained in this Agreement shall be deemed to constitute a
partnership or agency agreement between them for any purposes, including, but
not limited to federal income tax purposes. NETWORK and QWEST, in performing any
of their obligations hereunder, shall be independent contractors or independent
parties and shall discharge their contractual obligations at their own risk
subject, however, to the terms and conditions hereof. 

         24.7     SEVERABILITY. If any term, covenant or condition contained
herein is, to any extent, held invalid or unenforceable in any respect under the
laws governing this Agreement, the remainder of this Agreement shall not be
affected thereby, and each term, covenant or condition of this Agreement shall
be valid and enforceable to the fullest extent permitted by law.

         24.8     COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which taken together shall constitute one and the same
instrument.

executed by Landlord dated June 30, 1993 (the "Note"). Debt Service Payments
shall be defined according to the terms of the Note.

     4.2  ADDITIONAL RENT. This Lease is a NET LEASE, and Landlord shall not be
obligated to pay any charge or bear any expense whatsoever against or with
respect to the Premises except to the extent hereinafter provided, nor shall the
rent payable hereunder be subject to any reduction or offset whatsoever on
account of any such charge or otherwise, except as hereinafter provided. In
order that the Fixed Rent shall be absolutely net to Landlord, Tenant covenants
and agrees to pay, as Additional Rent, taxes, betterment assessments, insurance
costs, utility charges, and condominium charges with respect to the Premises as

          4.2.1 REAL ESTATE TAXES. Tenant shall pay, directly to Landlord,

foreseen and unforeseen, which are, at any time prior to or during the Term
hereof, imposed or levied upon or assessed against (A) the Premises, (B) any
Fixed Rent, Additional Rent or other sum payable hereunder or (C) this Lease, or

possession or use of the Premises; (ii) all gross receipts or similar taxes

<PAGE>   10


the acquisition, leasing or use of the Premises; and (iv) all charges for
utilities furnished to the Premises which may become a lien on the Premises
(collectively "taxes and assessments" or if singular "tax or assessment").

     Nothing contained in this Lease shall, however, require Tenant to pay any
franchise, corporate, estate, inheritance, succession capital levy or transfer
tax of Landlord, or any income, profits or revenue tax or charge upon the rent
payable by Tenant under this Lease (other than any tax referred to in clause

Premises.

          4.2.2 TAX FUND PAYMENTS. Tenant shall as Additional Rent, on the first
day of each month of the Term, make tax fund payments to Landlord. "Tax fund
payments" refer to such payments as Landlord shall reasonably determine to be
sufficient to provide in the aggregate a fund adequate to pay all taxes and
assessments referred to in Section 4.2.1 when they become due and payable. If
the aggregate of said tax fund payments is not adequate to pay all said taxes
and assessments, Tenant shall pay to Landlord the amount by which such aggregate
is less than the amount of all said taxes and assessments, such payment to be
made on or before the later of (a) 10 days after receipt by Tenant of notice
from Landlord of such amount, or (b) the 30th day prior to the last day on which
such taxes and assessments may be paid without interest or penalty. If Tenant
shall have made the aforesaid tax fund payments, Landlord shall pay to the
proper authority charged with the collection thereof, all taxes and assessments
referred to in Section 4.2.1, up to



                                      - 7 -

<PAGE>   11


the amount of such tax fund payments, and furnish Tenant, upon request,
reasonable evidence of such payment. Any balance remaining after such payment by
Landlord shall be accounted for to Tenant annually. In the event of any default
under the terms of this Lease, any part or all of said reserve fund may, at the
election of Landlord, be applied to any of Tenant's obligations under this
Lease.

          4.2.3 INSURANCE. Tenant shall take out and maintain throughout the
Term the following insurance protecting Landlord and the holder of any mortgage
as named insureds and with such additional insureds as Landlord from time to
time may designate by notice to Tenant, the premiums under which shall be
Additional Rent:

                4.2.3.1 All-risk insurance covering all buildings and
improvements now existing or hereafter erected upon the Premises, and all
equipment, fixtures, motors, machinery, furnishings and furniture installed in
or used in connection with the Premises, with such additional endorsements as
may be necessary to include coverage for vandalism and malicious conduct,
floods, water damage, earthquake and debris removal and demolition, with a
co-insurance provision of 80% or an agreed amount clause, in an amount at least
equal to the replacement cost of all such buildings, improvements, equipment,
fixtures, motors, machinery, furnishings and furniture (but not less than the
agreed amount if coverage is pursuant to an agreed amount clause) as such
replacement cost may from time to time be determined by agreement or by
appraisal made at Tenant's expense by an accredited insurance appraiser approved
by Landlord which may be required



                                      - 8 -

by either party whenever three years have elapsed since the last such agreement
or appraisal, or when alterations or additions increasing cost have been made.

                4.2.3.2 Rental value or similar insurance against abatement or
loss of rent in an amount equal to at least all the Fixed Rent and Additional
Rent payable for one year under this Article IV.

                4.2.3.3 Comprehensive general liability insurance indemnifying
Landlord and Tenant against all claims and demands for any injury to person or
property which may be claimed to have occurred on or about the Premises or on
the sidewalk or ways adjoining the Premises, in amounts which shall, at the
beginning of the Term, be at least equal to the limits set forth in Section 1.1,
and, from time to time during the Term, shall be for such higher limits, if any,
as are customarily carried in the area in which the Premises are located on
property similar to the Premises and used for similar purposes, and such
insurance shall include workmen's compensation insurance with statutory limits
covering all of Tenant's employees working on the Premises.

                4.2.3.4 Insurance against loss or damage from sprinklers and 
from leakage or explosion or cracking of boilers, pipes carrying steam or water,
or both, pressure vessels or similar apparatus, in the so-called "broad form"
and in such amounts as Landlord may reasonably require. Also, insurance against
such other hazards as may from time to time be required by Lender or any other
bank, insurance company or other lending institution holding a first mortgage on
the Premises, provided that such insurance is customarily carried in the area in
which the


                                      - 9 -

<PAGE>   13



Premises are located on property similar to the Premises and used for similar
purposes.

                4.2.3.5 At all times during the Term during the course of any
construction or renovation of any improvements or alterations on the Premises,
completed value form, "all physical loss", builder's risk~insurance on all work
being performed on the Premises, in such amounts as Landlord may reasonably
require and owner's contingent or protective liability insurance, covering
claims not covered by or under the terms of the above-mentioned comprehensive
general liability insurance, with combined single limit coverage at least equal
to the limits set forth in Section 1.1, or such higher limits as Landlord may
reasonably require, and workman's compensation insurance covering all persons
working on the job site or in connection with such construction.

                4.2.3.6 Policies for insurance required under the provisions of
Sections 4.2.3.1, 4.2.3.2, 4.2.3.4 and 4.2.3.5 (except as to liability and
workman's compensation insurance under Section 4.2.3.5) shall, in case of loss,
be first payable to Lender and any other holders of any mortgages on the
Premises under a standard non-contributing mortgagee's clause, and shall also
provide for the adjustment of claims with the insurers under such policies by
Landlord and Lender. All policies of insurance required under this Section 4.2.3
shall be deposited with Lender.

          All policies required under this Section 4.2.3 shall be obtained from
responsible companies qualified to do business in the state in which the
Premises are located and in good standing therein, which companies and the
amount of insurance



                                     - 10 -

<PAGE>   14



allocated thereto shall be subject to Landlord's approval. Tenant agrees to
furnish Landlord with policies of all such insurance prior to the beginning of
the Term hereof and of each renewal policy at least 30 days prior to the
expiration of the policy it renews. Each such policy shall be non-cancellable
with respect to the interest of Landlord and Lender and any other holders of any
mortgages on the Premises without at least 30 days' prior written notice
thereto. In the event provision for any such insurance is to be by a blanket
insurance policy, the policy shall allocate a specific amount of coverage to the
Premises, which allocation shall be sufficient in amount to satisfy the
requirements of this Section 4.2.3.

                     4.2.3.7 All insurance which is carried by either party with
respect to the Premises or to furniture, furnishings, fixtures or equipment
therein or alterations or improvements thereto, whether or not required, shall
include provisions which either designate the other party as one of the insured
or deny to the insurer acquisition by subrogation of rights of recovery against
the other party to the extent such rights have been waived by the insured party
prior to occurrence of loss or injury, insofar as, and to the extent that such
provisions may be effective without making it impossible to obtain insurance
coverage from responsible companies qualified to do business in the state in
which the Premises are located (even though extra premium may result therefrom).
Each party shall be entitled to have duplicates or certificates of any policies
containing such provisions. Each party hereby waives all rights of recovery
against the other for loss or injury against which the waiving party is
protected by insurance containing said non-subrogation provisions, reserving,



                                     - 11 -

<PAGE>   15



however, any rights with respect to any excess of loss or injury over the amount
recovered by such insurance.

          4.2.4 UTILITIES. Tenant shall pay directly to the proper authorities
charged with the collection thereof, or to the Furnace Brook Office Condominium
Association (the "Condominium Association"), as the case may be, all charges for
water, sewer, gas, electricity, telephone and other utilities or services used
or consumed on the Premises, whether called charge, tax, assessment, fee or
otherwise, including, without limitation, water and sewer use charges and taxes,
if any, all such charges to be paid as the same from time to time become due.

          4.2.5 COMMON CHARGES. Tenant shall pay directly to the Condominium
Association all common charges attributable to the Premises payable by Landlord,
as a Unit Owner of the Condominium to meet the Common Expenses of the
Condominium, as this amount may be determined and assessed pursuant to Article
VI of the By-Laws or pursuant to any other provisions of the Condominium
Documents or any other rules and regulations which may now or hereafter govern
the payment of common charges by Unit Owners of the Condominium. Tenant shall
pay said common charges at such time or times as they are assessed pursuant to
the Condominium Documents or the determination of the Board of Managers of the
Condominium, and shall, in all events, pay such assessed common charges at least
five (5) days prior to the due date for payment thereof.

said loss or damage is to be charged to or to be borne by Landlord, except that
Landlord shall in no event be indemnified or held harmless or exonerated from
any liability to Tenant or to any other person for any injury, loss, damage or
liability to the extent prohibited by law.

          5.1.10 YIELD UP. At the expiration of the Term or earlier termination
of this Lease: to surrender all keys to the Premises, to remove all furnishings,
fixtures, equipment and other personal property now or hereafter located in the
Premises, purchased or leased by Tenant with its own funds, which are not
affixed to the Premises or which Landlord has agreed in writing that Tenant may
remove at the



                                     - 17 -

expiration of the Term, to remove such installations made by Tenant as Landlord
may request and all Tenant's signs wherever located, to repair all damage caused
by such removal and to yield up the Premises (including all installations and
improvements made by Tenant, except for trade fixtures, and such of said
installations or improvements as Landlord shall request Tenant to remove),
broom-clean and in the same good order and repair in which Tenant is obliged to
keep and maintain the Premises by the provisions of this Lease.

          5.1.11 ESTOPPEL CERTIFICATE. Upon not less than 15 days' prior notice
by Landlord, to execute, acknowledge and deliver to Landlord a statement in
writing, addressed to such party as Landlord shall designate in its notice to
Tenant, certifying that this Lease is unmodified and in full force and effect
and that Tenant has no defenses, offsets or counterclaims against its
obligations to pay the Fixed Rent and Additional Rent and any other charges and
to perform its other covenants under this Lease (or, if there have been any
modifications that the same is in full force and effect as modified and stating
the modifications and, if there are any defenses, offsets or counterclaims,
setting them forth in reasonable detail), the dates to which the Fixed Rent and
Additional Rent and other charges have been paid and a statement that Landlord
is not in default hereunder (or if in default, the nature of such default, in

     5.2  NEGATIVE COVENANTS. Tenant covenants at all times during the Term and
for such further time as Tenant occupies the Premises or any part thereof:

          5.2.1 ASSIGNMENT AND SUBLETTING. Not to assign, transfer, mortgage or
pledge this Lease or to grant a security interest in Tenant's rights hereunder,
or to sublease (which term shall be deemed to include the granting of
concessions and licenses and the like) or permit anyone other than Tenant to
occupy all or any part of the Premises or suffer or permit this Lease or the
leasehold interest hereby created or any other rights arising under this Lease
to be assigned, transferred or encumbered, in whole or in part, whether
voluntarily, involuntarily or by operation of law, unless, in each instance (i)
the prior written consent of Landlord thereto shall have been obtained, which
consent shall not be unreasonably withheld, (ii) any defaults then existing with
respect to the obligations of Tenant under this Lease shall have been cured,
(iii) in the case of a proposed assignment, sublease or occupancy by another,
the proposed assignee, sublessee, or occupant is qualified to do business in the
state in which the Premises are located and such assignee, sublessee, or
occupant executes and delivers to Landlord an agreement satisfactory to Landlord
or its successors and assigns by which such assignee, sublessee or occupant
shall be bound by and shall assume all the obligations of Tenant under this
Lease relating to the portion or all of the Premises acquired by such assignee,
sublessee or occupant. Tenant may assign this Lease or sublet any portion or all
of the Premises to any corporation, partnership, trust, association or other
business or organization (x) directly or indirectly controlling and beneficially
owning Tenant, (y) directly or indirectly controlled by



                                     - 19 -

<PAGE>   23



and beneficially owned by Tenant, or to any successor of Tenant by merger,
consolidation or acquisition of substantially all of the assets of Tenant,
without the prior written consent of Landlord as required in (i) above, provided
that (a) Tenant shall deliver to Landlord at least 30 day's advance notice of
such proposed assignment or sublease, (b) in the case of a merger, consolidation
or sale, the net worth of Tenant's successor (determined in accordance with
generally accepted accounting principles) immediately after such merger,
consolidation or sale shall be at least equal to the net worth of Tenant
(similarly determined) immediately prior to such merger, consolidation or sale.

     In the event of a proposed subletting, Tenant's request for Landlord's
consent shall constitute an offer to Landlord to release from this Lease that
portion of the Premises proposed to be sublet, which offer Landlord may accept
within 30 days after receipt. If Landlord accepts such offer, this Lease shall
be deemed to have been amended by deleting such portion from the Premises and by
reducing the Fixed Rent by an amount equal to the product of the Fixed Rent
multiplied times a fraction, the numerator of which shall be equal to the net
rentable floor area of such portion deleted from the Premises and the
denominator of which shall be equal to the net rentable floor area of the
Premises including the deleted portion. Thereafter, for all purposes of this
Lease the Premises shall mean the balance of the premises demised hereunder
following deletion of the affected portion thereof, and all Additional Rent
payable hereunder shall be adjusted pro-rata, accordingly. Such amendment shall
be effective on the proposed effective date of the sublease as specified in
Tenant's



                                     - 20 -

<PAGE>   24



request for consent. Landlord's failure to accept Tenant's offer to release
shall not constitute a consent to the proposed subletting.

          Any attempted assignment, transfer, mortgage, pledge, grant of 
security interest, sublease or other encumbrance, except as permitted by this
Section 5.2.1, shall be void. No assignment, transfer, mortgage, grant of
security interest, sublease or other encumbrance, whether or not approved, and
no indulgence granted by Landlord to any assignee, sublessee or occupant shall
in any way impair Tenant's continuing primary liability (which after an
assignment or subletting shall be joint and several with the assignee or
sublessee) of Tenant hereunder, and no approval in a particular instance shall
be deemed to be a waiver of the obligation to obtain Landlord's approval in any
other case.

          5.2.2 OVERLOADING AND NUISANCE. Not to injure, overload, deface or
otherwise harm the Premises; nor commit any nuisance; nor permit the emission of
any objectionable noise or odor; nor make, allow or suffer any waste; nor make
any use of the Premises which is improper, offensive or contrary to any law or
ordinance or which will invalidate any of Landlord's insurance.

                                   ARTICLE VI

                               CASUALTY OR TAKING

     6.1  TERMINATION. In the event that the Premises, or any material part
thereof, shall be taken by any public authority or for any public use, or shall
be


                                     - 21 -

<PAGE>   25


destroyed or damaged by fire or casualty, or by the action of any public
authority, then this Lease may be terminated at the election of Landlord. Such
election, which may be made notwithstanding the fact that Landlord's entire
interest may have been- divested, shall be made by the giving of notice by
Landlord to Tenant within 30 days after the right of election accrues.

     6.2  RESTORATION. If Landlord does not exercise said election, this Lease
shall continue in force and a just proportion of the rent reserved, according to
the nature and extent of the damages sustained by the Premises, but not in
excess of the net proceeds of insurance recovered by Landlord under the rental
value or similar insurance carried by Tenant pursuant to Section 4.2.3.2, shall
be suspended or abated until the Premises, or what may remain thereof, shall be
put by Landlord in proper condition for use, which Landlord covenants to do with
reasonable diligence to the extent permitted by the net proceeds of insurance
recovered or damages awarded for such taking, destruction or damage and subject
to zoning and building laws or ordinances then in existence.

     6.3  AWARD. Irrespective of the form in which recovery may be had by law,
all rights to damages or compensation shall belong to Landlord in all cases.
Tenant hereby grants to Landlord all of Tenant's rights to such damages and
covenants to deliver such further assignments thereof as Landlord may from time
to time request.

                                    DEFAULTS

     7.1  EVENTS OF DEFAULT. (a) If Tenant shall default in the performance of
any of its obligations to pay the Fixed Rent or Additional Rent hereunder and if
such default shall continue for 10 days after notice from Landlord designating
such default or if within 30 days after notice from Landlord to Tenant
specifying any other default or defaults Tenant has not commenced diligently to
correct the default or defaults so specified or has not thereafter diligently
pursued such correction to completion, or (b) if Tenant becomes insolvent or
fails to pay its debts as they fall due, or (c) if the leasehold estate under
this Lease or any substantial part of the property of Tenant is taken on
execution, or by other process of law, or is attached or subjected to any other
involuntary encumbrance, or (d) if a receiver, trustee, custodian, guardian,
liquidator or similar agent is appointed with respect to Tenant, or if any such
person or a mortgagee, secured party or other creditor takes possession of the
Premises or of any substantial part of the property of Tenant, and, in either
case, if such appointment or taking of possession is not terminated within 30
days after it first occurs, or (e) if a petition is filed by or with the consent
of Tenant under any federal or state law concerning bankruptcy, insolvency,
reorganization, arrangement, or relief from creditors, and such petition is not
dismissed within 30 days thereafter, or (f) if Tenant or any Guarantor which is
a corporation dissolves or is dissolved or liquidates or adopts any plan or
commences any proceeding, the result of which is intended to include dissolution
or liquidation, then, Landlord may immediately or at any time



                                     - 23 -

<PAGE>   27



thereafter terminate this Lease whereupon all rights and liabilities of the
parties hereto shall cease.

     7.2  LANDLORD'S RIGHT TO CURE DEFAULTS. Landlord may, but shall not be
obligated to, cure, at any time, following 10 days' prior notice to Tenant,
except in cases of emergency when no notice shall be required, any default by
Tenant under this Lease; and whenever Landlord so elects, all costs and expenses
incurred by Landlord, including reasonable attorneys' fees, in curing a default
shall be paid by Tenant to Landlord as Additional Rent on demand.

     7.3  EFFECT OF WAIVERS OF DEFAULT. Any consent or permission by Landlord to
any act or omission which otherwise would be a breach of any covenant or
condition herein, or any waiver by Landlord of the breach of any covenant or
condition herein, shall not in any way be held or construed (unless expressly so
declared) to operate so as to impair the continuing obligation of any covenant
or condition herein, or otherwise, except as to the specific instance, operate
to permit similar acts or omissions.

     The failure of Landlord to seek redress for violation of, or to insist upon
the strict performance of, any covenant or condition of this lease shall not be
deemed a waiver of such violation nor prevent a subsequent act, which would have
originally constituted a violation, from having all the force and effect of an
original violation. The receipt by Landlord of rent with knowledge of the breach
of any covenant of this Lease shall not be deemed to have been a waiver of such
breach by Landlord, or by Tenant, unless such waiver be in writing signed by the
party to be charged. No

                                      

                                     - 24 -

<PAGE>   28



consent or waiver, express or implied, by Landlord to or of any breach of any
agreement or duty shall be construed as a waiver or consent to or of any other
breach of the same or any other agreement or duty.

     7.4  NO ACCORD AND SATISFACTION. No acceptance by Landlord of a lesser sum
than the Fixed Rent, Additional Rent or any other charge then due shall be
deemed to be other than on account of the earliest installment of such rent or
charge due, unless Landlord elects by notice to Tenant to credit such sum
against the most recent installment due, nor shall any endorsement or statement
on any check or any letter accompanying any check or payment as rent or other
charge be deemed a waiver, an agreement or an accord and satisfaction, and
Landlord may accept such check or payment without prejudice to Landlord's right
to recover the balance of such installment or pursue any other remedy in this
Lease provided.

                                  ARTICLE VIII

                                    MORTGAGES

     8.1  RIGHTS OF MORTGAGE HOLDERS. The word "mortgage" as used herein
includes mortgages, deeds of trust or other similar instruments evidencing other
voluntary liens or encumbrances, and modifications, consolidations, extensions,
renewals, replacements and substitutes thereof. The word "holder" shall mean a
mortgagee, and any subsequent holder or holders of a mortgage. Landlord and
Tenant hereby acknowledge that Lender is the current and only holder of a
mortgage on the Premises. Until Lender or any other holder of a mortgage
(hereinafter



                                     - 25 -

<PAGE>   29



"holder" or "holder of a mortgage") shall enter and take possession of the
Premises for the purpose of foreclosure, such holder shall have only such rights
of Landlord as are necessary to preserve the integrity of this Lease as
security. Upon entry and taking possession of the Premises for the purpose of
foreclosure, such holder shall have all the rights of Landlord. Notwithstanding
any other provision of this Lease to the contrary, including without limitation
Section 9.4, no such holder of a mortgage shall be liable either as mortgagee or
as assignee, to perform, or be liable in damages for failure to perform, any of
the obligations of Landlord unless and until such holder shall enter and take
possession of the Premises for the purpose of foreclosure. Upon entry for the
purpose of foreclosure, such holder shall be liable to perform all of the
obligations of Landlord accruing from and after such entry subject to and with
the benefit of the provisions of Section 9.4, provided that a discontinuance of
any foreclosure proceeding shall be deemed a conveyance under said provisions to
the owner of the Premises. No Fixed Rent, Additional Rent or any other charge
shall be paid more than 30 days prior to the due dates thereof and payments made
in violation of this provision shall (except to the extent that such payments
are actually received by a mortgagee in possession or in the process of
foreclosing its mortgage) be a nullity as against such holder of a mortgage and
Tenant shall be liable for the amount of such payments to such holder. Tenant
agrees on request of Landlord to execute and deliver from time to time any
agreement which may be necessary to implement the provisions of this 
Section 8.1.

     8.2  LEASE SUPERIOR OR SUBORDINATE TO MORTGAGES. This Lease is and shall
continue to be subject and subordinate to the presently existing mortgage held
by Lender or any future mortgages secured by the Premises, and to any and all
advances hereafter made thereunder, and to the interest of Lender and any other
holder or holders thereof in the Premises. Lender shall have the election to
subordinate the mortgage held by Lender to this Lease, exercisable by filing
with the appropriate recording office a notice of such election, whereupon this
Lease shall have priority over such mortgage. A copy of such filing shall be
given to Tenant. Such election by the Lender shall not affect priority with
respect to this Lease of any other mortgage.

     Any mortgage or other voluntary lien or other encumbrance recorded
subsequent to the recording of the notice or short form referred to in Section
9.3 shall be subject and subordinate to this Lease unless Landlord and the
holder of any such subsequent mortgage and Lender and any other holders of
mortgages prior to such subsequent mortgage elect to subordinate this Lease to
such subsequent mortgage and to any and all advances thereafter made thereunder
and to the interest of the holder thereof in the Premises, such election to be
exercisable by Landlord and Lender and all such other holders by filing with the
appropriate recording office (a) a notice of such election and (b) an agreement
between the holder of such subsequent mortgage and Tenant, consented to by
Lender and the other holders of all mortgages having priority over such
subsequent mortgage, by the terms of which such holder will agree to recognize
the rights of Tenant under this Lease and to accept Tenant as



                                     - 27 -

<PAGE>   31



tenant of the Premises under the terms and conditions of this Lease in the event
of acquisition of title by such holder through foreclosure proceedings or
otherwise and Tenant will agree to recognize the holder of such subsequent
mortgage as Landlord in such event, which agreement shall be made expressly to
bind and inure to the benefit of the successors and assigns of Tenant and of
such holder and upon anyone purchasing said Premises at any foreclosure sale
brought by such holder. Tenant and Landlord agree to execute and deliver any
appropriate instruments necessary to carry out the agreements contained in this
Section 8.2. Any such subsequent mortgage to which this Lease is subordinated
may contain such terms, provisions and conditions as the holder deems usual or
customary.

     8.3  LENDER'S CONSENT. Landlord and Tenant hereby agree and acknowledge
that this Lease shall be of no force and effect unless and until approved and
consented to by Lender, as evidenced by Lender's signature hereto.

     8.4  RIGHTS OF HOLDER OF MORTGAGE. No act or failure to act on the part of
Landlord which would entitle Tenant under the terms of this Lease, or by law, to
be relieved of Tenant's obligations hereunder or to terminate this Lease, shall
result in a release or termination of such obligations or a termination of this
Lease unless (i) Tenant shall have first given written notice of Landlord's act
or failure to act to Lender or any other of Landlord's mortgagees of record, if
any, specifying the act or failure to act on the part of Landlord which could or
would give basis to Tenant's rights; and (ii) Lender or any other such
mortgagees, after receipt of such notice, have failed or refused to correct or
cure the condition complained of within a reasonable



                                     - 28 -

<PAGE>   32



time thereafter; but nothing contained in this Section 8.4 shall be deemed to
impose any obligation on Lender or any other such mortgagees to correct or cure
any condition. "Reasonable time" as used above means and includes a reasonable
time to obtain possession of the mortgaged premises if Lender or any other such
mortgagee elects to do so and a reasonable time to correct or cure the condition
if such condition is determined to exist.

                                   ARTICLE IX

                            MISCELLANEOUS PROVISIONS

     9.1  NOTICES FROM ONE PARTY TO THE OTHER. All notices required or permitted
hereunder shall be in writing and addressed, if to the Tenant, at the Original
Address of Tenant or such other address as Tenant shall have last designated by
notice in writing to Landlord and, if to Landlord, at the Original Address of
Landlord or such other address as Landlord shall have last designated by notice
in writing to Tenant. Any notice shall be deemed duly given when mailed to such
address postage prepaid, registered or certified mail, return receipt requested,
or when delivered to such address by hand.

     9.2  QUIET ENJOYMENT. Landlord agrees that upon Tenant's paying the rent
and performing and observing the terms, covenants, conditions and provisions on
its part to be performed and observed, Tenant shall and may peaceably and
quietly have, hold and enjoy the Premises during the Term without any manner of
hindrance or molestation from Landlord or anyone claiming under Landlord,
subject, however, to the terms of this Lease.

<PAGE>   33



     9.3  LEASE NOT TO BE RECORDED. Landlord and Tenant agree that they will not
record this Lease. Both parties shall, upon the request of either, execute and
deliver a notice or short form of this Lease in such form, if any, as may be
permitted by applicable statute. If this Lease is terminated before the Term
expires the parties shall execute, deliver and record an instrument
acknowledging such fact and the actual date of termination of this Lease, and
Tenant hereby appoints Landlord its attorney-in-fact, coupled with an interest,
with full power of substitution to execute such instrument.

     9.4  BIND AND INURE; LIMITATION OF LANDLORD'S LIABILITY. The obligations of
this Lease shall run with the land, and this Lease shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns. No owner of the Premises shall be liable under this Lease except for
breaches of Landlord's obligations occurring while owner of the Premises.
Neither Landlord nor any trustee or beneficiary thereof shall have any personal
liability hereunder, it being expressly agreed that all liability of Landlord
hereunder shall be limited to the assets of Landlord which comprise the Premises
but no upon other assets of Landlord.

     9.5  ACTS OF GOD. In any case where either party hereto is required to do
any act, delays caused by or resulting from Acts of God, war, civil commotion,
fire, flood or other casualty, labor difficulties, shortages of labor, materials
or equipment, government regulations, unusually severe weather, or other causes
beyond such party's reasonable control shall not be counted in determining the
time during which work shall be completed, whether such time be designated by a
fixed date, a fixed

                     

                                     - 30 -

<PAGE>   34



time or a "reasonable time", and such time shall be deemed to be extended by the
period of such delay.

     9.6  LANDLORD'S DEFAULT. Landlord shall not be deemed to be in default in
the performance of any of its obligations hereunder unless it shall fail to
perform such obligations and such failure shall continue for a period of 30 days
following receipt of notice from Tenant or such additional time as is reasonably
required to correct any such default after notice has been given by Tenant to
Landlord specifying the nature of Landlord's alleged default.

     9.7  BROKERAGE. Tenant warrants and represents that it has had no dealings
with any broker or agent in connection with this Lease and covenants to defend
with counsel approved by Landlord, hold harmless and indemnify Landlord from and
against any and all cost, expense or liability for any compensation, commissions
and charges claimed by any broker or agent with respect to Tenant's dealings in
connection with this Lease or the negotiation thereof.

     9.8  APPLICABLE LAW AND CONSTRUCTION.

          9.8.1 APPLICABLE LAW. This Lease shall be governed by and construed in
accordance with the laws of the state in which the Premises are located. If any
term, covenant, condition or provision of this Lease or the application thereof
to any person or circumstances shall be declared invalid, or unenforceable by
the final ruling of a court of competent jurisdiction having final review, the
remaining terms, covenants, conditions and provisions of this Lease and their
application to persons or circumstances shall not be affected thereby and shall
continue to be


                                     - 31 -

<PAGE>   35



enforced and recognized as valid agreements of the parties, and in the place of
such invalid or unenforceable provision, there shall be substituted a like, but
valid and enforceable provision which comports to the findings of the aforesaid
court and most nearly accomplishes the original intention of the parties.

          9.8.2 NO OTHER AGREEMENT. There are no oral or written agreements
between Landlord and Tenant affecting this Lease. This Lease may be amended, and
the provisions hereof may be waived or modified, only by instruments in writing
executed by Landlord and Tenant.

          9.8.3 TITLES. The titles of the several Articles and Sections
contained herein are for convenience only and shall not be considered in
construing this Lease.

          9.8.4 "LANDLORD" AND "TENANT". Unless repugnant to the context, the
words "Landlord" and "Tenant" appearing in this Lease shall be construed to mean
those named above and their respective heirs, executors, administrators,
successors and assigns, and those claiming through or under them respectively.
If there be more than one tenant the obligations imposed by this Lease upon
Tenant shall be joint and several.

          9.9  SUBMISSION NOT AN OFFER. The submission of a draft of this Lease
or a summary of some or all of its provisions does not constitute an offer to
lease or demise the Premises, it being understood and agreed that neither
Landlord nor Tenant shall be legally bound with respect to the leasing of the
Premises unless and until this Lease has been executed by both Landlord and
Tenant and a fully executed copy delivered.

4.0  INTERCONNECTION PURSUANT TO SECTION 251(c)(2)

     Subject to the terms and conditions of this Agreement, Interconnection of
the Parties' facilities and equipment pursuant to Section 4.0 for the
transmission and routing of Telephone Exchange Service traffic and Exchange
Access traffic shall be established on or before the corresponding
"Interconnection Activation Date" shown for each such LATA within the
Commonwealth of Massachusetts on Schedule 4.0. Schedule 4.0 may be revised and
supplemented from time to time upon the mutual agreement of the Parties to
reflect the Interconnection in the additional LATA in Massachusetts pursuant to
Section 4.5 by attaching one or more supplementary schedules to such schedule.

     4.1      Scope

     Section 4.0 describes the physical architecture for Interconnection of the
Parties' facilities and equipment for the transmission and routing of Telephone
Exchange Service Traffic and Exchange Access traffic pursuant to Section
251(c)(2) of the Act. Sections 5.0 and 6.0 prescribe the specific logical trunk
groups (and traffic routing parameters) which will be configured over the
physical connections described in this Section 4.0 related to the transmission
and routing of Telephone Exchange Service Traffic and Exchange Access traffic,
respectively. Other trunk groups, as described in this Agreement, may be
configured using this architecture.

     4.2      Physical Interconnection of Networks

              The Parties mutually agree that the following are possible methods
for interconnecting facilities:

              1. Collocation using physical collocation used unless technical
feasibility or space limitations make that model impractical; or

              2. via purchase of facilities from either Party by the other
Party;

              3. upon mutual agreement as to technical feasibility,
interconnection on a mid-span basis; or

              4. upon mutual agreement any other technically feasible basis
permitted by law.

Each Party ("Providing Party") shall provide to the other Party ("Collocation
Party"), upon request, Physical Collocation for the placement of the Collocation
Party's transport facilities and equipment, pursuant to the terms and conditions
of the Providing Party's applicable tariffs on file with the appropriate
regulatory agency and License Agreements, as necessary for Interconnection or
for access to unbundled Network Elements (pursuant to Section 9.0). Transport
Facilities may be purchased at the rates, terms and conditions set forth in each
Party's Intrastate Private Line or Interstate Access Services tariffs.

              4.2.1 The Parties agree that the existing interconnection
architecture shall provide the model for network interconnection following the
execution of this Agreement. The Parties will cooperatively work to implement
either of the alternative models upon request of either Party or pursuant to the
Joint Grooming Plan and forecast under Section 5.3.1. TCG will establish a point
of interconnection at each and every access tandem where TCG desires to provide
connection to end-offices subtending those access tandems. Alternatively, TCG
may elect to interconnect directly to BA's End Offices for completion of
Telephone Exchange Service Traffic to BA end-users. BA will connect at each TCG
combination End Office Tandem serving as an Access Tandem in each LATA in BA's
operating territory within Massachusetts. Such interconnecting facilities will
conform at a minimum. to the telecommunications industry standard, Bellcore
Standard No. TR-NWT-0499. Signal Transfer Point, Signaling System 7 ("SS7")
connectivity will be used at each appropriate interconnection point. BA will
provide out-of-band signaling using Common Channel Signaling Access capability
where technically and economically feasible, in accordance with the technical
specifications set forth in the Bellcore Guidelines for SS-7 interconnection
(TR-TSV-000905). The Parties agree that their facilities shall provide the
necessary on-hook, off-hook answer and disconnect supervision and shall hand off
calling number ID when available and technically feasible. The Parties further
agree that in the event either Party interconnects through the purchase of
facilities and/or services from the other Party, the available tariff rates will
apply to the purchase of such facilities and/or services.

              4.2.2 The Parties mutually agree to establish trunk groups
sufficient in capacity to provide a grade of service, availability and service
quality which is comparable to that provided on interoffice trunk groups within
BA's network and which meets all appropriate and relevant industry-accepted
quality, reliability and availability standards. Notwithstanding the foregoing,
each Party may construct its network, including the interconnecting facilities,
to achieve optimum cost effectiveness and network efficiency.

     4.3      Numbering Plans

              The Parties agree to bill Telephone Exchange Service Calls made by
their respective Customers to NXX Codes served by another Party based on the V&H
rating points assigned to the NXX Codes of the other Party. The V&H rating
points of the originating Customer and the terminating Customer will determine
the rating of calls.

     4.4      Technical Specifications

              4.4.1 TCG and BA shall work cooperatively to install and maintain
a reliable network. TCG and BA shall exchange appropriate information (e.g.,
maintenance contact numbers, network information, information required to comply
with law enforcement and other security agencies of the Government and such
other information as the Parties shall mutually agree) to achieve this desired
reliability.

              4.4.2 TCG and BA shall work cooperatively to apply sound network
management principles by invoking network management controls to alleviate or to
prevent congestion.

              4.4.3 The publication "Bellcore Technical Publication
TR-INS-000342; High Capacity Digital Special Access Service, Transmission
Parameter Limits and Interface Combinations" describes the practices,
procedures, specifications and interfaces generally utilized by BA and is
referenced herein to assist the Parties in meeting their respective
Interconnection responsibilities related to Electrical/Optical Interfaces.

     4.5      Interconnection in Additional LATA

              4.5.1 If TCG determines to offer Telephone Exchange Services in
the other LATA in which BA also offers Telephone Exchange Services in
Massachusetts, TCG shall provide written notice to BA of the need to establish
Interconnection in such LATA pursuant to this Agreement.

              4.5.2 The notice provided in Section 4.5.1 shall include (i) TCG's
switch location in the LATA; (ii) TCG's desired Network Interconnection Points
(NIP); (iii) TCG's requested Interconnection Activation Date; and (iv) a
non-binding forecast of trunking requirements.

              4.5.3 Unless otherwise agreed by the Parties, the Interconnection
Activation Date in the new LATA shall be no more than the one hundred and
fiftieth (150th) calendar day following the day on which TCG delivered notice to
BA of the need to establish Interconnection pursuant to Section 4.5.1. Within
ten (10) business days of BA's receipt of the TCG's Notice, BA and TCG shall
confirm in writing the Network Interconnection Points, and Interconnection
Activation Date for the LATA.

5.0      TRANSMISSION AND ROUTING OF TELEPHONE EXCHANGE SERVICE TRAFFIC PURSUANT
         TO SECTION 251(c)(2)

     5.1      Scope of Traffic

     Section 5.0 prescribes parameters for trunk groups (the "Traffic Exchange
Trunks") to be effected over the Interconnections specified in Section 4.0 for
the transmission and routing of Local Traffic and IntraLATA Toll Traffic between
the Parties' respective Telephone Exchange Service Customers.

     5.2      Switching System Hierarchy

     Either Party may deploy End Office switches, Tandem switches, or
combination End Office Tandem switches as required to meet their respective
network design requirements.

                                      -16-
<PAGE>   17
     The Parties shall jointly engineer and configure Traffic Exchange Trunks
over the physical Interconnection arrangements covered in Section 4.2 as
follows:

              5.3.1 The Parties shall maintain the existing network
configuration pending the development and implementation of a mutually
acceptable Joint Grooming Plan.

              5.3.2 Notwithstanding anything to the contrary in this Section
5.0, if the two-way traffic volumes between any two Central Office Switches at
any time exceeds the CCS busy hour equivalent of one DS1, the Parties shall
within sixty (60) days after such occurrence add trunks or establish new direct
trunk groups consistent with the grades of service and quality parameters set
forth in the Joint Grooming Plan; provided, however, nothing in this Section 5.3
shall require a Party to establish new direct trunk groups on or before the date
which is one hundred and twenty (120) days after the applicable Interconnection
Activation Date; provided, however, that if such traffic volume is exceeded
within such one hundred and twenty (120) day period, such Party shall establish
new direct trunk groups on the date which is the later of sixty (60) days after
such occurrence or one hundred and twenty-one (121) days after the
Interconnection Activation Date.

     5.4      Signaling

              5.4.1 Where available, CCIS signaling shall be used by the Parties
to set up calls between the Parties' Telephone Exchange Service networks. If
CCIS signaling is unavailable, Multi-Frequency ("MF") signaling shall be used by
the Parties. Each Party shall charge the other Party equal and reciprocal rates
for CCIS signaling in accordance with applicable tariffs. During the term of
this Agreement neither Party shall charge the other Party additional usage-
sensitive rates for SS7 queries made for Local Traffic.

              5.4.2 The publication "Bellcore Special Report SR-TSV-002275, BOC
Notes on the LEC Networks - Signaling" describes the practices, procedures and
specifications generally utilized by BA for signaling purposes and is referenced
herein to assist the Parties in meeting their respective Interconnection
responsibilities related to signaling.

              5.4.3 The Parties shall cooperate on the exchange of Transactional
Capabilities Application Part ("TCAP") messages to facilitate interoperability
of CCIS-based features between their respective networks, including all CLASS
features and functions on IntraLATA calls only, to the extent each Party offers
such features and functions to its Customers. All CCIS signaling parameters will
be provided including, calling Party number ("CPN"), originating line
information ("OLI"), calling Party category and charge number. The Parties will
provide each other with Destination Point Codes necessary to rout call
associated and non-call associated (eg.,TCAP) messages.

              5.4.4 Each Party shall provide trunk groups where available that
are configured utilizing the B8ZS ESF protocol for 64 Kbps clear channel
transmission to allow for ISDN interoperability between the Parties' respective
networks.

     5.5      Grades of Service

     The Parties shall initially engineer and shall jointly monitor and enhance
all trunk groups consistent with the Joint Grooming Plan.

     5.6      Measurement and Billing

              5.6.1 For billing purposes, each Party shall pass Calling Party
Number ("CPN") information on each call carried over the Traffic Exchange
Trunks; provided that so long as the percentage of calls passed with CPN is
greater than ninety percent (90%), all calls exchanged without CPN information
shall be billed as either Local Traffic or IntraLATA Toll Traffic in direct
proportion to the minutes of use of calls exchanged with CPN information.

              5.6.2 Measurement of billing minutes (except for originating
800/888 calls) shall be in actual conversation seconds. Measurement of billing
minutes for originating 800/888 calls shall be in accordance with applicable
tariffs (i.e., access minutes as defined in FCC No. 1 tariff will be used).

              5.6.3 Where CPN is not available in a LATA for greater than ten
percent (10%) of the traffic, the Party sending the traffic shall provide
factors to determine the jurisdiction, as well as local vs. toll distinction, of
the traffic. Such factors shall be supported by call record details that will be
made available for review upon request.




                                      -17-
<PAGE>   18
Where a Party is passing CPN but the receiving Party is not properly receiving
or recording the information, the Parties shall cooperatively work to correctly
identify the traffic, and establish a mutually agreeable mechanism that will
prevent improperly rated traffic. Notwithstanding this, if any improperly rated
traffic occurs, the Parties agree to reconcile it.

              5.6.4 Notwithstanding the above, if either Party has technical
difficulty meeting the requirements of Section 5.6 the Parties agree to work
cooperatively to develop interim measurements and billing procedures for
determining traffic jurisdiction, directionality and the Tandem/End Office mix
for Traffic Exchange Trunks. The interim measurement and billing procedures
shall apply for a period not to exceed twelve (12) months unless a different
time period is mutually agreed to by the Parties.

     5.7      Reciprocal Compensation Arrangements -- Section 251(b)(5)

              5.7.1 Reciprocal Compensation only applies to the transport and
termination of Local Traffic billable by BA or TCG which a Telephone Exchange
Service Customer originates on BA's or TCG's network for termination on the
other Party's network within the same LATA except as provided in Section 13.6
below.

              5.7.2 Except as provided in Section 5.7.3 below, the Parties shall
compensate each other for transport and termination of Local Traffic in an equal
and symmetrical manner as provided in the Pricing Schedule. No additional
charges, including port or transport charges, shall apply for the termination of
Local Traffic. When Local Traffic is terminated over the same trunks as other
traffic, any port or transport or other applicable access charges related to
such other traffic shall be prorated to be applied only to such other traffic.

              5.7.3 As ordered by the Department in the Consolidated
Arbitrations, when BA terminates Local Traffic to TCG subscribers using TCG's
switch and the TCG switch serves a geographic area comparable to the area served
by the BA tandem switch, BA shall pay to TCG the tandem interconnection charge
set forth in the Pricing Schedule.

              5.7.4 The Reciprocal Compensation arrangements set forth in this
Agreement are not applicable to Switched Exchange Access Service, cellular
traffic or to any other intraLATA calls originated on a third Party carrier's
network on a 1+ presubscribed basis or a casual dialed (10XXX or 101XXXX) basis.
All Switched Exchange Access Service and all IntraLATA Toll Traffic shall
continue to be governed by the terms and conditions of the applicable federal
and state tariffs.

              5.7.5 Compensation for transport and termination of all traffic
which has been subject to performance of INP by one Party for the other Party
pursuant to Section 13.0 shall be as specified in Section 13.6.

              5.7.6 When either Party delivers seven (7) or ten (10) digit
translated intraLATA 800/888 service to the other Party for termination, the
originating Party shall provide the terminating Party with billing records in
industry standard format (EMR) if required by the terminating Party. The
originating Party may bill the terminating Party for the delivery of the traffic
at local reciprocal compensation rates. The terminating Party may not bill the
originating Party reciprocal compensation under this Agreement. The Party that
is providing the 800/888 service shall pay the database inquiry charge per the
Pricing Schedule to the Party that performed the database inquiry.

     5.8      Municipal Calling Service

     The Parties shall work cooperatively to facilitate each Party's public
service obligations to provide its end user customers with toll free Municipal
Calling Service ("MCS") or similar services which treat certain toll calls as
local. Such cooperation shall include the sharing of certain account and toll
free municipal ("TFM") codes on a daily or other mutually agreeable basis and
working with other industry participants to satisfactorily resolve MCS related
measurement and billing issues associated with implementation of intraLATA
presubscription.

6.0      TRANSMISSION AND ROUTING OF EXCHANGE ACCESS TRAFFIC PURSUANT TO SECTION
         251(c)(2)

     6.1      Scope of Traffic

     Section 6.0 prescribes parameters for certain trunk groups ("Access Toll
Connecting Trunks") to be established over the Interconnections specified in
Section 4.0 for the




                                      -18-
<PAGE>   19
transmission and routing of Exchange Access traffic between the Parties'
Telephone Exchange Service Customers and Interexchange Carriers ("IXCs").

     6.2      Trunk Group Architecture and Traffic Routing

              6.2.1 The Parties shall jointly establish Access Toll Connecting
Trunks by which they will jointly provide tandem-transported Switched Exchange
Access Services to Interexchange Carriers to enable such Interexchange Carriers
to originate and terminate traffic from/to the Parties' Customers.

              6.2.2 Access Toll Connecting Trunks shall be used solely for the
transmission and routing of Exchange Access to allow the Parties' Customers to
connect to or be connected to the interexchange trunks of any Interexchange
Carrier which is connected to either of the Parties' Access Tandem.

              6.2.3 The Access Toll Connecting Trunks may be two-way trunks
connecting an End Office Switch utilized to provide Telephone Exchange Service
and Switched Exchange Access in a given LATA to an Access Tandem Switch utilized
to provide Exchange Access in such LATA.

              6.2.4 For Meet Point Billing at TCG's option, TCG's End Office may
subtend BA's Access Tandem. In the event TCG elects this the option, TCG's End
Office switch (i.e., Routing Point) shall subtend the BA Access Tandem nearest
to such Routing Point, as measured in airline miles utilizing the V&H coordinate
method. If TCG establishes an Access Tandem in Massachusetts, BA may at its
option subtend such TCG Access Tandem for Meet Point Billing purposes.
Alternative configurations will be discussed as part of the Joint Grooming Plan.

     6.3      Meet Point Billing Arrangements

              6.3.1 For the purposes of this section, the Parties agree that
Tandem and subtending End Office arrangements shall be according to LERG with
respect to interconnection between the Parties for jointly-provided Switched
Exchange Access arrangements, except as mutually amended by the Parties. The
Parties agree that where they jointly provide Switched Access Service, they will
share revenues received for such services in the manner described in this
Section:

              6.3.1.1 The Parties will use the New York Intrastate Access
Settlement Pool Inc. ("NYSP") as their vendor to bill the Switched Access
Exchange Service charges to the appropriate Interexchange carrier on behalf of
both Parties based on the respective Switched Exchange Access Service Tariff
rates of the Parties (single bill, multiple tariff), in accordance with the
existing agreement executed on March 21, 1996 between the Parties and NYSP which
is incorporated by reference herein. In the event that agreement is terminated
before the termination of this Agreement, the Parties agree that it shall be
renewed or another vendor shall be selected by the Parties to perform those
functions under a similar agreement in Massachusetts. The Parties will work
cooperatively to establish and maintain these billing arrangements. In the event
the NYSP or subsequent vendor cannot perform the billing functions the Party
providing the first point of tandem switching may perform the billing collection
and revenue distribution function on a timely basis.

              6.3.1.2 In accordance with the March 21, 1996 agreement between
the Parties and the NYSP, the Parties will bear the charges of the NYSP to each
of the Parties in direct proportion to the revenues distributed by the NYSP to
each of except where one Party causes the NYSP to incur unique and directly
attributable costs for extraordinary activities, then that Party shall bear the
cost of those activities.

              6.3.1.3 Retroactive adjustments such as jurisdictional factor
changes by the Switched Exchange Access Service customer, if applied, will be
passed through and the Parties will "true-up" revenues based on such
adjustments.

              6.3.1.4 In the 128 LATA for conventionally routed Tandem
subtending access arrangements where there is one Tandem and the Tandem Party
switches directly to the End Office using its own facilities, the NYSP will
remit to the End Office Party seventy percent (70%) of all switched access
revenues that Party would have collected were it providing the entire switched
access service, net of NYSP fees. The NYSP will remit to the Tandem Party the
remainder of all switched access revenues collected, net of NYSP fees.




                                      -19-
<PAGE>   20
              6.3.1.5 In the 128 LATA for double Tandem routed traffic, where
the Tandem Party switches to the End Office Party's Tandem using its own
facilities, the revenue distribution is as noted above in Section 6.3.1.4,
except that the percentages shall be applied at ninety percent (90%) rather than
seventy percent (70%). However, if the Tandem Party requests a conventional
routing directly into the End Office Party's End Office, and the End Office
Party does not make a direct End Office connection available to the Tandem Party
within two (2) months of the request, the billing will occur as if the traffic
were conventionally routed and the Tandem Party was switching directly to the
End Office, as stated in the paragraph above.

              6.3.1.6 Nothing in this section changes or otherwise modifies BA's
provision of switched carrier access pursuant to its applicable tariffs. These
arrangements shall apply only when TCG or BA provide alternative switched
carrier access services to interexchange carriers ("IXCs") for origination or
termination of calls between an IXC and either Parties' Customers.

              6.3.2.1 For jointly provided wireless traffic, the Party receiving
the traffic directly from the wireless carrier shall bill that traffic at its
appropriate tariffed rates. That Party shall keep twenty five percent (25%) of
revenues collected and shall distribute the remaining seventy five percent (75%)
of the revenues to the End Office Party. The Parties agree to continue
negotiations with respect to this provision, with the intent of agreeing on
mutually acceptable revisions within 30 business days after the Effective Date.

              6.3.2.2 Nothing in this section changes or otherwise modifies BA's
provision of wireless services pursuant to its applicable tariffs. These
arrangements shall apply only when TCG or BA provide alternative wireless
services to wireless carriers for origination or termination of calls between a
wireless carrier and either Parties' Customers.

              6.3.3 The provisions of Sections 6.3.1.4, 6.3.1.5 and 6.3.2.1 are
contingent upon Switched Exchange Access Service charges as they exist as of the
time of execution of this Agreement. The Parties recognize that the FCC or the
DPU may change, revise, or otherwise modify Switched Exchange Access Service. In
the event that the DPU or the FCC modifies or changes the current Switch
Exchange Access Service or wireless rate structures, including but not limited
to redirecting the allocation of the recovery of various costs between rate
elements, the Parties will renegotiate revised Meet Point Billing Arrangements
to ensure a fair and reasonable allocation of revenues. Until such time as the
Parties agree upon revised Meet Point Billing Arrangements the provisions of
Sections 6.3.1.4, 6.3.1.5 and 6.3.2.1 will remain in effect subject to a true-up
to reflect the revised Meet Point Billing Arrangements.

7.0      TRANSPORT AND TERMINATION OF OTHER TYPES OF TRAFFIC

     7.1      Information Services Traffic

              7.1.1 Each Party shall route Information Services Traffic which
originates on its own network to the appropriate information services
platform(s) connected to the other Party's network. TCG and BA will jointly
establish a dedicated trunk group to the BA information services tandem switch.
This trunk group will be utilized to allow TCG to route Information Services
Traffic originated on its network to BA, and to allow TCG to receive Information
Services Traffic from BA for a trial of interim number portability arrangements
related to Information Services Traffic.

              7.1.2 In Massachusetts, subscriber priced Information Services,
including but not limited to Interactive Information Network Service, shall be
available when the originating Party orders separate trunks to the terminating
Party for termination of such traffic only. The terminating Party will charge
the originating Party $.03 per minute of use for transport and switching. The
terminating Party will make available, upon request from the originating Party,
rating service at a charge of $.03 per message plus a $15,000 non-recurring
charge, provided that the originating Party provides the terminating Party with
call records free of charge. Under rating service the terminating Party will
rate calls placed by the Originating Party's Customers and terminating to
Information Provider services on the terminating Party's network, according to
the rates established by such Information Providers. The terminating Party will
then provide the rated call records to the originating Party. The terminating
Party will not bill and collect for such rated calls. Alternatively, at the
originating Party's option, it may purchase a rating table from the terminating
Party at the rate set forth in the Pricing Schedule. The originating Party is



                                      -20-
<PAGE>   21
responsible for all payments due the Information Providers to whose programs
that Party's Customer places calls, and other obligations and relationships with
such Information Providers.

              7.1.3 Nothing in this agreement shall restrict either Party from
offering to its Exchange Service Customer the ability to block the completion of
Information Services Traffic.

     7.2      Tandem Transit Service ("Transit Service")

              7.2.1 "Transit Service" means the delivery of certain traffic
between TCG and a LEC by BA over the Traffic Exchange Trunks. The following
traffic types will be delivered: (i) Local Traffic or IntraLATA Toll Traffic
originated from TCG to such LEC and (ii) Local Traffic or IntraLATA Toll Traffic
originated from such LEC and terminated to TCG.

              7.2.2 Subject to Section 7.2.4, the Parties shall compensate each
other for Transit Service as follows:

              (a)     TCG shall pay BA for Local Traffic TCG originates over the
                      Transit Service at the rate specified in the Pricing
                      Schedule plus any additional charges or costs such
                      terminating LEC imposes or levies on BA for the delivery
                      or termination of such traffic, including any switched
                      access charges; and

              (b)     BA shall pay TCG for Local, InterLATA, or IntraLATA Toll
                      Traffic terminated to TCG from such LEC at the appropriate
                      reciprocal compensation rates described in Section 5.7,
                      InterLATA access rates, or (where BA delivers such traffic
                      pursuant to the Department's primary toll carrier plan or
                      other similar plan) at TCG's applicable switched access
                      rates or local termination rate, whichever is appropriate.

              7.2.3 While the Parties agree that it is the responsibility of a
LEC to enter into arrangements to deliver Local Traffic to TCG, they acknowledge
that such arrangements are not currently in place and an interim arrangement is
necessary to ensure traffic completion. Accordingly, until the earlier of (i)
the date on which either Party has entered into an arrangement with such LEC to
deliver Local Traffic to TCG or (ii) one hundred and eighty (180) days after the
Interconnection Activation Date, BA will deliver and TCG will terminate Local
Traffic originated from such LEC without charge to one another.

              7.2.4 BA expects that all networks involved in Transit Service
will deliver each call to each involved network with CCIS and the appropriate
Transactional Capabilities Application Part ("TCAP") message to facilitate full
interoperability of those services supported by BA as noted in Section 1.12 and
billing functions. In all cases, TCG is responsible to follow the Exchange
Message Record ("EMR") standard and exchange records with both BA and the
terminating LEC to facilitate the billing process to the originating network.

              7.2.5 For purposes of this Section 7.2, BA agrees that it shall
make available to TCG, at TCG' s sole option, any transiting arrangement BA
offers to another LEC at the same rates, terms and conditions provided to such
other LEC.

     7.3      Dedicated Transit Service

              7.3.1 "Dedicated Transit Service" provides for the dedicated

<PAGE>   22
              7.4.1 Definition. 911 and E911 traffic refers to emergency calls
originated by dialing 9-1-1. Other emergency calls include calls routed to an
operator position by dialing 0-. The Parties agree to cooperate to ensure the
seamless operation of emergency call networks, including 911, E-911 and 0-
calls.

              7.4.2 The Parties agree to establish unique Trunk Groups to
properly route E911 traffic where the end user subscriber has dialed 911. Calls
originating on TCG's network will be routed to the appropriate BA 911 Tandem
and/or selective router for routing to the PSAP ("PSAP") serving the end user.
This Trunk Group will be established between TCG's switching entity(ies) and
BA's 911 Tandems as a one-way CAMA MF trunk group. When SS7 connectivity is
available, the Parties agree to implement CCS trunking. The capacity of these
trunk groups will be determined pursuant to existing State, local and BA
guidelines. BA shall provide TCG with the following:

            a)    Processes and requirements for ordering trunks. TCG shall be
                  responsible for issuing E911 trunk group orders to BA.

            b)    Trunk group specifications. The Parties agree these trunks
                  will use either CAMA MF or SS7 signaling.

            c)    Tandem CLLI codes, circuit IDs.

            d)    Description of BA diversity for facility routing.

            e)    Maintenance requirements for this trunk group, including, but
                  not limited to contact points, escalation lists, including 24
                  by 7 availability, etc.

              7.4.3 TCG will interconnect to the BA 911/E911 selective
router/911 tandems which serve the areas in which TCG provides exchange
services, for the provision of 911/E911 services and for access to all
sub-tending Public Safety Answering Points ("PSAPs"). BA will provide TCG with
the appropriate CLLI codes and specifications of the tandem serving area.

              7.4.4 Path and route diverse interconnections for 911/E911 shall
be made at the Network Interconnection Points (NIPs), or other points as
necessary and mutually agreed.

              7.4.5 BA will provide TCG with an electronic interface through
which TCG shall input and provide a daily update of 911/E911 database
information related to appropriate TCG Customers. BA will provide TCG with the
Master Street Address Guide ("MSAG") so that TCG can ensure the accuracy of the
data transfer. Additionally, BA shall assist TCG in identifying the appropriate
person in each municipality for the purpose of obtaining the ten-digit
Subscriber number of each PSAP. If electronic data entry is not available, BA,
as the operator of the Automatic Location Identifier (ALI) database, will
establish interim processes and procedures to receive and process TCG customer
information within twenty-four (24) hours. BA has provided TCG with the record
input format.

              7.4.6 BA and TCG will use their best efforts to facilitate the
prompt, robust, reliable and efficient interconnection of TCG systems to the
911/E911 platforms.

              7.4.7 BA and TCG will work cooperatively to arrange meetings with
PSAPs to answer any technical questions the PSAPs, or county or municipal
coordinators may have regarding the 911/E911 arrangements.

              7.4.8 TCG will compensate BA for connections to its 911/E911
pursuant to the Pricing Schedule.

              7.4.9 TCG and BA will comply with all applicable rules and
regulations pertaining to the provision of 911/E911 services in the Commonwealth
of Massachusetts.

              7.4.10 BA agrees to furnish to TCG at a charge set forth in the
Pricing Schedule for a one (1) year subscription for the list of 10 digit
administrative numbers for the PSAPs in the Eastern Massachusetts LATA (LATA
128). TCG agrees to hold this information proprietary and will use the
information solely for the purpose of routing 0 minus for emergency calls from
the TCG Operator Services platform to the PSAPs. BA agrees to provide TCG with
updates to this information in accordance with the terms and conditions of the
Emergency Bulletin Service subscription.

or FCC or by law.

     9.7      Provisioning of Unbundled Links

     The following coordination procedures shall apply for new unbundled Links
and the conversions of "live" Telephone Exchange Services to unbundled Links
(herein after referred to as "hot cuts"):

              9.7.1 TCG shall request unbundled Links from BA by delivering to
BA a valid electronic transmittal Service Order using the BA electronic ordering
platform (as cooperatively designed and implemented to meet the minimum
requirements for information exchange needed to order and provision services to
certified local exchange carriers and enhanced to support industry standards as
developed for interconnection services) or another mutually agreed upon system.
Within 2 business days of BA's receipt of a Service Order, BA shall provide TCG
the firm order commitment ("FOC") date.

              9.7.2 BA agrees to accept from TCG at the time the service request
is submitted for scheduled conversion of hot cut unbundled Link orders, a
desired date and time (the "Scheduled Conversion Time") in the "A.M." (12:01
midnight to 12:00 noon) or "P.M." (12:01 noon to 12:00 midnight) (as applicable,
the "Conversion Window") for the hot cut.

              9.7.3 BA shall test for TCG dial tone at the POT Bay by testing
through the tie cable provisioned between the BA main distributing frame and the
TCG expanded interconnection node forty eight (48) hours prior to the Scheduled
Conversion Time.

              9.7.4 Not less than one hour prior to the Scheduled Conversion
Time, either Party may contact the other Party and unilaterally designate a new
Scheduled Conversion Time (the "New Conversion Time"). If the New Conversion
Time is within the Conversion Window, no charges shall be assessed on or waived
by either Party. If, however, the New Conversion Time is outside of the
Conversion Window, the Party requesting such New Conversion Time shall be
subject to the following:

         If BA requests the New Conversion Time, the applicable Service Order
         Charge shall be waived; and




                                      -25-
<PAGE>   26
         If TCG requests the New Conversion Time, TCG shall be assessed a
         Service Order Charge in addition to the Line Connection Charge that
         will be incurred for the New Conversion Time.

              9.7.5 Except as otherwise agreed by the Parties for a specific
conversion, such as large cutovers of 10 lines or more that have negotiated
intervals, the Parties agree that the time interval expected from disconnection
of BA's "live" Telephone Exchange Service to the connection of an unbundled
Network Element at the TCG Collocation node's POT Bay will be accomplished
within a window of time of sixty (60) minutes or less. If a conversion exceeds
the specified interval and such delay is caused solely by BA (and not by a
contributing Delaying Event, BA shall waive the applicable tariffed Service
Order Charge for such element. If TCG has ordered INP with the installation of a
Link, BA will coordinate the implementation of INP with the Link conversion
during the above stated intervals at no additional charge.

              9.7.6 If TCG requests or approves a BA technician to perform
services in excess of or not otherwise contemplated by the Line Connection
charge, BA may charge TCG for any additional and reasonable labor charges to
perform such services.

              9.7.7 If as the result of end user actions, (e.g., Customer not
ready ["CNR"]), BA cannot complete requested work activity when a technician has
been dispatched to the site, TCG will be assessed a non-recurring charge
associated with this visit. This charge will be the sum of the Service Order
Charge and Premises Visit Charge as specified in the D.P.U. Mass. No. 10 Part M
Section 1.3.2.

              9.7.8 Until such time as the DPU approves a non-recurring
unbundled network element Service Order Charge(s), an interim non-recurring
Service Order Charge shall be assessed on a per link (or other unbundled network
element) basis. The interim Service Order Charge shall equal the Central Office
Line Connection Charge to install a business network access line, as specified
in DPU Mass. No. 10, Part M, Section 1.3.1.

     9.8      Maintenance of Unbundled Network Elements

     If (i) TCG reports to BA a Customer trouble, (ii) TCG requests a dispatch,
(iii) BA dispatches a technician, and (iv) such trouble was not caused by BA's
facilities or equipment in whole or in part, then TCG shall pay BA a trip charge
of $60.00 and $28.15 per quarter hour for time associated with said dispatch
beyond the first 1/2 hour. In addition this charge also applies when the end
user contact as designated by TCG is not available at the appointed time. TCG
accepts responsibility for initial trouble isolation and providing BA with
appropriate dispatch information based on their test results. If as the result
of TCG instructions, BA is erroneously requested to dispatch within a BA Central
Office or to a POT Bay ("dispatch in"), a charge of $100.00 per occurrence will
be assessed to TCG by BA.

     9.9      Acknowledgments Related to Unbundled Network Elements

              9.9.1 TCG acknowledges that BA's provision of unbundled Links
provides it with local loop transmission from the central office to the
customer's premises, unbundled from local switching or other services.

              9.9.2 TCG acknowledges that BA's provision of unbundled switched
transport provides it with local transport from the trunk side of a wireline
local exchange carrier switch unbundled from switching or other services.

              9.9.3 TCG acknowledges that BA's provision of unbundled line-side
Ports and unbundled trunk-side Ports makes available local switching unbundled

will now receive from Party B. Upon receipt of a signed letter of agency from
the Customer (and an associated service order) assigning the number to Party B,
Party A will implement an arrangement whereby all calls to the original
telephone number(s) will be forwarded to a new telephone number(s) designated by
Party B. Party A will route the forwarded traffic to Party B over the
appropriate Local/IntraLATA Trunks as if the call had originated on Party A's
network.

              13.2.2 Party B will become the customer of record for the original
Party A telephone numbers subject to the INP arrangements. Party A shall use its
reasonable efforts to consolidate into as few billing statements as possible all
collect, calling card, and 3rd-number billed calls associated with those
numbers, with sub-account detail by retained number or Party B can have Party A
block such calls. At Party B's sole discretion, such billing statement shall be
delivered to Party B in an agreed-upon format via either electronic file
transfer, daily magnetic tape, or monthly magnetic tape.

              13.2.3 Party A will update its Line Information Database ("LIDB")
listings for retained numbers, and restrict or cancel calling cards associated
with those forwarded numbers as directed by Party B.

              13.2.4 Within two (2) business days of receiving notification from
the Customer, Party B shall notify Party A of the Customer's termination of
service with Party B, and shall further notify Party A as to that Customer's
instructions regarding its telephone number(s). Party A will reinstate service
to that Customer, cancel the INP arrangements for that Customer's telephone
number(s), or redirect the INP arrangement to another INP-participating-LEC
pursuant to the Customer's instructions at that time.

     13.3     Procedures for Providing INP Through Route Indexing

     Upon mutual agreement, BA will deploy a Route Index arrangement which
combines direct trunks, provisioned between BA's and TCG'S end offices, with
trunk side routing translations. Under this arrangement, inbound calls to a
ported number will be pointed at a route index that sends the call to a
dedicated trunk group, built as a direct final, for the sole purpose of
facilitating completion of calls to a ported number. BA will coordinate with TCG
to provide this solution in a mutually agreeable and administratively manageable
manner (e.g., NXX level) so as to minimize switch resource utilization for both
Parties.

     13.4     Procedures for Providing INP Through Full NXX Code Migration

     Where either Party has activated an entire NXX for a single Customer, or
activated a substantial portion of an NXX for a single Customer with the
remaining numbers in that NXX either reserved for future use or otherwise
unused, if such Customer chooses to receive service from the other Party, the
first Party shall cooperate with the second Party to have the entire NXX
reassigned in the LERG (and associated industry databases, routing tables, etc.)
to an End Office operated by the second Party. Such transfer will be
accomplished with appropriate coordination between the Parties and subject to
appropriate industry lead-times for movements of NXXs from one switch to
another.

     13.5     Other Interim Number Portability Options



                                      -28-
<PAGE>   29
     TCG may also request direct inward dial trunks pursuant to applicable
tariffs. If information on the interim number portability is made available to
any Party it will be made available to TCG.

         13.6  Receipt of Terminating Compensation on Traffic to INP'ed Numbers

     The Parties agree that under INP terminating compensation on calls to
INP'ed numbers should be received by each Customer's chosen LEC as if each call
to the Customer had been originally addressed by the caller to a telephone
number bearing an NPA-NXX directly assigned to the Customer's chosen LEC. In
order to accomplish this objective where INP is employed, the Parties shall
utilize the process set forth in this Section 13.6 whereby terminating
compensation on calls subject to INP will be passed from the Party which
performs the INP (the "Performing Party") to the other Party for whose Customer
the INP is provided (the "Receiving Party").

              13.6.1 The Parties shall individually and collectively track and
quantify INP traffic between their networks based on the CPN of each call by
identifying CPNs which are INP'ed numbers. The Receiving Party shall charge the
Performing Party for each minute of INP traffic at the INP Traffic Rate
specified in Section 13.6.3 in lieu of any other compensation charges for
terminating such traffic.

              13.6.2 By the Interconnection Activation Date in each LATA, the
Parties shall jointly estimate for the prospective year, based on historic data
of all traffic in the LATA, the percentages of such traffic that if dialed to
telephone numbers bearing NPA-NXXs directly assigned to a Receiving Party (as
opposed to the INP'ed number) would have been subject to (i) Reciprocal
Compensation ("Reciprocal Local Traffic"), (ii) Reciprocal Compensation for
IntraLATA Toll Traffic ("Reciprocal IntraLATA Toll Traffic"), (iii) appropriate
intrastate Feature Group D ("FGD") charges pursuant to Section 6.3 ("Intra
Traffic"), (iv) interstate FGD charges pursuant to Section 6.3 ("Inter
Traffic"), or (v) handling as Local Traffic under transiting arrangements
between the Parties ("Transit Traffic"). On the date which is six (6) months
after the Interconnection Activation Date, and thereafter on each succeeding six
(6) month anniversary of such Interconnection Activation Date, the Parties shall
establish new INP traffic percentages to be applied in the prospective six (6)
month period, based on actual INP traffic percentages from the preceding six (6)
month period.

              13.6.3 The INP Traffic Rate shall be equal to the sum of:

                        (Local Reciprocal Traffic percentage times the Local
                  Reciprocal Compensation Rate set forth in the Pricing
                  Schedule) plus (IntraLATA Toll Reciprocal Traffic percentage
                  times BA's effective intrastate FGD rates, less rates for
                  tandem switching and transport functions performed by the
                  Performing Party) plus (Interstate IntraLATA Traffic
                  percentage times BA's effective interstate FGD rates, less
                  rates for tandem switching and transport functions performed
                  by the Performing Party).

A rate of zero shall be applied to the Transit Traffic percentage.

14.0 NUMBER RESOURCES ASSIGNMENTS
     14.1 The Parties agree that the North American Numbering Plan ("NANP")
Administrator for the state will provide all NANP Administrator functions to the
Parties in accordance with industry standards and guidelines, including the
Central Office Guidelines.

     14.2 For as long as BA functions as the NANP Administrator, the Parties
agree that these services will be provided without charge.

     14.3 The Parties will each be responsible for the electronic input of their
respective number assignment information into the BELLCORE-administered LERG
systems (BRADS and RDBS).

     14.4 Codes will be assigned to rate center(s) as required the rules of the
DPU or FCC.

     14.5 The Parties will maintain utilization and forecast of number resources
and file utilization reports as required by industry standards and fora.

     14.6 The Parties will age and re-use numbers on a schedule as required by
industry practices.



                                      -29-

     14.7 Nothing in this document can be construed to require either Party to
mirror the retail rate plans or structures of the other.

     14.8 The Parties agree to engage in fair and equitable treatment of each
other in the assignment of NXX Codes such that the Parties are afforded the
opportunity to obtain available codes upon request

     14.9 If either Party functions as the NANP Administrator, that Party agrees
to meet all industry guidelines regarding timing of assignment of codes.

     14.10 The Parties shall cooperate to mutually perform VETS testing on all
NXXs opened by TCG in Massachusetts.

15.0 DIALING PARITY -- SECTION 251(B)(3)

     BA shall provide Local Dialing Parity as required under Section 251(b)(3)
of the Act in the following manner: Telephone numbers are provided pursuant to
Section 14.0; Directory Assistance is provided pursuant to Section 19.2;
Directory Listings are provided pursuant to Section 19.1; and Operator Services

16.0 ACCESS TO RIGHTS-OF-WAY -- SECTION 251(b)(4)

     Each Party shall provide the other Party access to its poles, ducts,
rights-of-way and conduits it owns or controls, to the extent permitted by law
and as required by Section 224 of the Act or Department Order, on terms,
conditions and prices comparable to those offered to any other entity pursuant
to the attached.

17.0 DATABASES AND SIGNALING

     BA shall provide TCG with interfaces to access BA's databases, including
LIDB and 800/888, as well as DCAS or any other system that BA may subsequently
make available in Massachusetts for ordering and provisioning purposes, and
associated signaling necessary for the routing and completion of TCG's traffic
through the provision of SS7 under its applicable tariffs.

18.0 REFERRAL ANNOUNCEMENT

     When a Customer changes its service provider from BA to TCG, or from TCG to
BA, and does not retain its original telephone number, the Party formerly
providing service to such Customer shall provide a referral announcement
("Referral Announcement") on the abandoned telephone number which provides
details on the Customer's new number. Referral Announcements shall be provided
reciprocally, free of charge to either the other Party or the Customer, for a
period of not less than four (4) months after the date the Customer changes its
telephone number in the case of business Customers and not less than sixty (60)
days after the date the Customer changes its telephone number in the case of
residential Customers. However, if either Party provides Referral Announcements
for a period different than the above respective periods when its Customers
change their telephone numbers, such Party shall provide the same level of
service to Customers of the other Party.

19.0 DIRECTORY SERVICES ARRANGEMENTS

     BA will provide certain directory services to TCG as defined herein. In
this Section 19.0 of this Agreement, references to TCG Customer telephone
numbers means telephone numbers falling within NXX codes directly assigned to
TCG and to numbers which are retained by TCG's on the Customer's behalf pursuant
to Interim Telecommunications Number Portability arrangements described in
Section 13 of this Agreement.

     19.1     Directory Listings and Directory Distributions

              19.1.1 BA will include TCG's Customers telephone numbers in all of
its "White Pages" and "Yellow Pages" directory listings (including electronic
directories) and directory assistance databases associated with the areas in
which TCG provides services to such Customers, and will distribute such
directories to such Customers, in an identical and transparent to the manner in
which it provides those functions for its own Customers' telephone numbers.

              19.1.2 BA will include all TCG NXX codes associated with the
geographic areas to which each directory pertains, along with BA's own NXX codes
in any maps or lists of such codes which are contained in the general reference
portions of the directories. TCG's NXX codes shall appear in such maps or lists
in the same manner as BA's codes NXX information.

              19.1.3 TCG will provide BA with its directory listings and daily
updates to those listings (including new, changed, and deleted listings) in a
mutually agreed upon format at no charge.

              19.1.4 BA will accord TCG's directory listing information the same
level of confidentiality which BA accords its own directory listing information.

              19.1.5 BA shall provide TCG at no charge with (i) one basic single
line white and yellow page directory listing per business Customer number, or
one basic single line white page directory listing per residence Customer

as may be mutually





                                      -31-
<PAGE>   32
agreed to by both Parties. Both Parties shall use their best efforts to ensure
the accurate listing of such information.

              19.1.7 The Parties will work cooperatively to establish an
electronic interface for the submission of the TCG Customer information to
include the TCG Customer's telephone numbers in BA Directory listings and
directory customer database from one Party to the other, e.g., DCAS or a similar
system. The Parties agree to work within the national standards fora, such as
the Ordering and Billing Forum, to establish, approve and implement an industry
standard electronic interface.

              19.1.8 The Parties agree to work cooperatively to implement
interim processes and procedures for submission of the required information
under this Section.

              19.1.9 Commingled listings will appear in the appropriate
configuration for the particular directory (e.g., either interfiled or
sectionalize by locality).

              19.1.10 Foreign Listings. The Party publishing the directories
agrees to afford the Customers of the other Party the ability to purchase a
listing in a foreign directory pursuant to applicable tariffs.

              19.1.11 Yellow Page Maintenance

              BA will work cooperatively with TCG so that Yellow Page
advertisements purchased by Customers who switch their service to TCG (including
Customers utilizing Interim Telephone Number Portability) are maintained without
interruption. BA will allow TCG Customers to purchase new yellow pages
advertisements without discrimination, under the identical rates, terms and
conditions that apply to BA's customers.

              19.1.12 Information Pages

              BA will include in the "Information Pages" or comparable section
of its White Pages Directories for the geographic areas served by TCG, telephone
numbers provided by TCG for TCG's installation, repair and customer service,
including appropriate identifying logo. Such listings shall appear in the manner
that such information appears for subscribers of BA and other LECs. BA shall not
charge TCG for inclusion of this information.

     19.2     Directory Assistance ("DA") and Operator Services

     Under this option, BA will provide Directory Assistance to TCG end users on
behalf of TCG.

     BA will offer Directory Assistance ("DA") service to TCG's customers served
by TCG's own switch over separate trunk groups ordered or provided by TCG to the
BA TOPS switch(es) as specified by BA. Access to the BA DA platform from TCG's
local switch requires that TCG utilize Feature Group C ("FG-C") Modified
Operator Services Signaling. The Interoffice Transmission Facility ("IOF")
mileage rate for the facility will be based on airline mileage using V&H
coordinate methods from the TCG location to the nearest BA TOPS. Trunk
terminations at the TOPS switch(es) require TCG to purchase trunk ports at rates
specified in the Pricing Schedule. For each trunk group TCG must indicate the DA
option selected as set forth in 19.2.2 (a), (b) and (c) immediately following.
BA also provides TCG, using the unbundled local switching element, access to
this optional service either through dedicated IOF and trunk ports or on shared
operator service trunks between the end office in which they have unbundled
local switching ports and the TOPS switches. Additional per minute of use
("MOU") local switching charges will apply for all calls which interconnect from
the unbundled local switching ports to the BA TOPS as described in the Pricing
Schedule.

              19.2.1  Directory Assistance

              This option provides TCG end users access to Telephone Directory
Assistance operators via 411, 555-1212, or 1+ (NPA) 555-1212 dialing.

              19.2.2  Directory Assistance with Branding

              This service allows TCG to select only one of the three options as
follows:

              *(a) TCG may provide BA with a TCG branded, introductory Directory
Assistance and Operator Services announcement which will be played for all TCG
end users completing DA or Operator Services calls over the trunk group to the
BA TOPS.

              *(b) TCG may request BA branded announcement.

              *(c) TCG may request an unbranded, generic announcement.

              This message may be a maximum of eighteen (18) seconds and may be
recorded by TCG or, at TCG's request, by BA. A minimum of two (2) audio cassette
recordings of the TCG branding announcement must be forwarded to BA.

              Rates for requests for Directory Assistance with branding will be
billed to TCG and are set forth in the Pricing Schedule.

     19.3     Directory Assistance Call Completion ("DACC")

     This option provides for automatic connection of a TCG end user calling BA
DA to the published telephone number requested.

     After the BA DA operator provides the requested number, a recorded service
message will offer to connect the caller to that number for a specified
additional charge.

     The caller can accept the offer for DACC by depressing a button (touch
tone) or responding by voice (dial), as instructed by the voice message.

     The DACC charge will apply as set forth in the Pricing Schedule. In
addition, for calls originating from a facilities-based TCG switch or for calls
from TCG unbundled local switching line ports, there will be charges to
terminate the call from the TOPS tandem to the called party. These include the
per minute of use Unbundled Tandem Transport Charges ("UTTC") assessed for each
call transported between the TOPS tandem and the end office, the per minute of
use Tandem Transit Switching Charge ("TTSC") assessed for each call that
traverses a BA tandem switch, and the appropriate per minute of use charges for
reciprocal compensation ("UNRCC" or "UCRCC") depending on the terminating end
office switch, as set forth in the Pricing Schedule.

              DACC is available to TCG residence and business customers and from
public telephones on a collect, bill to third number or calling card basis. The
charge appropriate to the billing option used will apply in addition to the DACC
charge.

              DACC is available with all telephone numbers in the BA DA database
except:

                               -      non-published telephone numbers
                               -      interLATA numbers
                               -      700, 800 and 900 numbers

              When a caller requests more than one number for Directory
Assistance, DACC is offered only for the first eligible listing that was
selected by the operator.

              The DACC charge applies only to calls actually completed.

              The DACC charge will be credited for completion of calls to the
wrong number, incomplete connections or calls with unsatisfactory transmission
as set forth in Section 19.4 following.

     Rates for requests for DACC will be billed to TCG as set forth in the
Pricing Schedule.

     19.4     Directory Assistance Credits

     A credit allowance will apply to TCG for directory inaccessibility, wrong
numbers, cut-offs or poor transmission. When the TCG end user reports to the BA
directory assistance operator such a call and the number requested, the number
provided and the reason the number provided is incorrect, the number of calls
for which a credit will apply will be developed by the BA DA operator and
credited to TCG identifying the specific TCG end user to whom the credit
applies.

     19.5  Direct Access to Directory Assistance ("DADA")

     Direct Access to Directory Assistance ("DADA") is a database service that
provides for access to BA listings by a TCG operator. The DADA database is a
physically distinct entity from the BA DA database, populated with identical
listing data, and updated from the same source on a daily basis.

              TCG is required to arrange for Interconnection to the database. BA
will interconnect at any technically feasible point designated by TCG.

              BA will provide TCG with a User Guide for training its agents.

              Rates and Charges for DADA are set forth in the Pricing Schedule.

     19.6     Inward Operator Services

     Inward Operator Services enables the TCG end user or its operator service
provider to be connected to the BA Traffic Operation Position Systems ("TOPS")
office(s) for the purpose of providing operator services to their end users.
There are two types of Inward Operator Services:

              (i)     Busy Line Verification ("BLV"):

     BLV is an option where, at the request of TCG's end user or its operator
service provider, a BA operator will attempt to determine the status of an
exchange service line (e.g., conversation in progress, available to receive a
call or out of service) and report to TCG's end user or its operator service
provider.

              (ii)    Busy Line Verification/Interrupt ("BLV/I")

     BLV/I is an option where, at the request of TCG's end user or its operator
service provider, a BA operator determines and reports that a conversation is in
progress on an exchange service line and subsequently interrupts such
conversation to request that the conversation be terminated so that TCG's end
user can attempt to complete a call to the line.

              Inward Operator Services are provided over trunk groups ordered by
TCG or its alternate operator service provider to the BA TOPS switch(es) as
specified by BA.

              Inward Operator Services cannot be provided on ported telephone
numbers, telephone number which forward calls using Call Forwarding Variable
service features.

             - BA will provide BLV and BLV/I for telephone numbers provided in
        its operating territory.

             - The BA operator will respond to one telephone number per call on
        requests for BLV or BLV/I.

             - BA will designate which TOPS switch(es) services which NXXs and
        make such information available to TCG.

             - TCG shall order Inward Operator Services as set forth in this
        Section.

             - TCG and its customer shall indemnify and save BA harmless against
        all claims that may arise from either party to the interrupted call or
        any other person.

              Rates and Charges for Inward Operator Services are set forth in
the Pricing Schedule.

     19.7     Operator Service ("OS")

     Under this option, BA shall provide for the routing of Operator Services
calls dialed by TCG subscribers directly to either the TCG Operator Services
platform or to the BA Operator Services platform as specified by TCG.

     BA will offer OS to TCG customers served by TCG switches over separate
trunk groups ordered or provided by TCG to the BA TOPS switch(es) as specified
by BA. Access to the BA OS platform from TCG's local switch requires that TCG
utilize Feature Group C Modified




                                      -34-
<PAGE>   35
Operator Services Signaling. The Interoffice Transmission Facility mileage rate
for the facility will be based on airline mileage using V&H coordinate methods
from the TCG location to the nearest BA TOPS. Trunk terminations at the TOPS
switch(es) require TCG to purchase trunk ports at rates specified in the Pricing
Schedule. For each trunk group, TCG must indicate the branding option selected
as set forth in Sections 19.2.2 (a), (b), and (c) preceding. BA also provides
TCG, using the unbundled local switching element, access to this optional
service either through dedicated IOF and trunk ports or on shared operator
service trunks between the end office in which they have unbundled local
switching ports and the TOPS switches. Additional per minute of use (MOU) local
switching charges will apply for all calls which interconnect from the unbundled
local switching ports to the BA TOPS at rates set forth in the Pricing Schedule.

     19.8     0+ Mechanized Operator Calls (Calling Card, Collect, Bill to Third
              Number):

     This option is available for TCG to provide their end user the ability,
through the mechanized BA operator interface, to complete calls via 0+ dialing
with alternate billing capabilities without live operator assistance. Alternate
billing call completions can be Calling Card, Collect or Bill to Third Number.

     0+ Mechanized calls may be provided over the same DA trunk groups which
establish interconnection from the TCG switch or the trunk groups which provide
interconnection from the TCG unbundled local switching line ports to the BA
TOPS.

     Rates for requests for 0+ Mechanized Calls will be billed to TCG and are
set forth in the Pricing Schedule. In addition, for calls originating from a
facilities-based TCG switch or for calls from TCG unbundled local switching line
ports, there will be charges to terminate the call from the TOPS tandem to the
called party. These include the per minute of use Unbundled Tandem Transport
Charges ("UTTC") assessed for each call transported between the TOPS tandem and
the end office, the per minute of use Tandem Transit Switching Charge ("TTSC")
assessed for each call that traverses a BA tandem switch, and the appropriate
per minute of use charges for reciprocal compensation ("UNRCC" or "UCRCC")
depending on the terminating end office switch, as set forth in the Pricing
Schedule.

<PAGE>   36
     19.9    0- Operator Handled Calls (Calling Card, Collect, Bill to Third 
Number)

     This option is available for TCG to provide their end user, through the BA
operator, the ability to complete intraLATA calls via 0- dialing with alternate
billing capabilities and live operator assistance. Alternate billing call
completions can be Calling Card, Collect or Bill to Third Number, Station to
Station and Person to Person.

     0- Operator Handled Calls may be provided over the same DA trunk groups
which establish interconnection from the TCG switch or the trunk groups which
provide interconnection from the TCG unbundled local switching line ports to the
BA TOPS.

     Rates for requests for 0- Operator Handled Calls will be billed to TCG and
are set forth in the Pricing Schedule. In addition, for calls originating from a
facilities-based TCG switch or for calls from TCG unbundled local switching line
ports, there will be charges to terminate the call from the TOPS tandem to the
called party. These include the per minute of use Unbundled Tandem Transport
Charges ("UTTC") assessed for each call transported between the TOPS tandem and
the end office, the per minute of use Tandem Transit Switching Charge ("TTSC")
assessed for each call that traverses a BA tandem switch, and the appropriate
per minute of use charges for reciprocal compensation ("UNRCC" or "UCRCC")
depending on the terminating end office switch, as set forth in the Pricing
Schedule.

     19.10    Operator Emergency Bulletin Service

     This option provides TCG with emergency numbers of police, fire, ambulance
and Public Safety Answering Points (PSAP) in the BA serving area so that TCG
operators can connect callers directly to the proper emergency bureaus.

              The BA Operator Emergency Bulletin Service lists the emergency,
police, fire, ambulance and PSAP telephone numbers by municipality and in
alphabetical order for each of the areas served by BA.

              Operator Emergency Bulletin Service is available for use by TCG
operators for the sole purpose of assisting callers in reaching an emergency
bureau.

              Operator Emergency Bulletin Service is a copy of BA's own
emergency bulletin. This agreement includes one annual copy of the bulletin plus
periodic updates during the year. Independent telephone companies emergency
numbers are not included.

              Rates and charges for Operator Emergency Bulletin service are set
forth in the Pricing Schedule.

     19.11    Operator Passthrough Service

     This option provides TCG's end users with access to operators of their
Presubscribed Interexchange Carriers ("IC") for operator assisted call
completion. This option applies only when the Presubscribed IC provides Operator
Services for TCG's end users for calls originating from a particular LATA and is
capable of receiving calls passed through it by BA in that LATA.

     BA will, when requested by TCG's end user, connect that end user to a
specified IC for operator call completion provided that IC offers operator
services in that end user's originating LATA and is capable of receiving calls
passed through to it by BA in that LATA.

     If the IC does not provide Operator Services for TCG's end user, at the
option of the IC, BA will provide TCG's end user with access to an IC designated
Operator Services Provider or to a BA provided announcement which will direct
TCG's end user to contact their Presubscribed IC for dialing instructions.

              The Operator Passthrough charge is applied on an operator work
second basis, and rated using the 0-Operator Handled calls in the Pricing
Schedule.

              TCG will be assessed this charge on calls that are passed through
to either the Presubscribed IC's operator, or a BA provided recording indicating
that the IC does not provide service in that area.

              Rates and charges applied to Operator Passthrough Service are set
forth in the Pricing Schedule.

term of this Agreement, each Party shall provide the other Party with a rolling,
six (6) calendar month, non- binding forecast of its traffic and volume
requirements for the services and Network Elements provided under this Agreement
in the form and in such detail as agreed by the Parties. Notwithstanding Section
28.6.1, the Parties agree that each forecast provided under this Section 20.3
shall be deemed "Proprietary Information" under Section 28.6.

     20.4 Any Party that is required pursuant to this Agreement to provide a
forecast (the "Forecast Provider") or the Party that is entitled pursuant to
this Agreement to receive a forecast (the "Forecast Recipient") with respect to
traffic and volume requirements for the services and Network Elements provided
under this Agreement may request in addition to non-binding forecasts required
by Section 20.3 that the other Party enters into negotiations to establish a
forecast (a "Binding Forecast") that commits such Forecast Provider to purchase,
and such Forecast Recipient to provide, a specified volume to be utilized as set
forth in such Binding Forecast. The Forecast Provider and Forecast Recipient
shall negotiate the terms of such Binding Forecast in good faith and shall
include in such Binding Forecast provisions regarding price, quantity, liability
for failure to perform under a Binding Forecast and any other terms desired by
such Forecast Provider and Forecast Recipient. Notwithstanding Section 28.6.1,
the Parties agree that each forecast provided under this Section 20.4 shall be
deemed "Proprietary Information" under Section 28.6.

     20.5 Each Party is individually responsible to provide facilities within
its network which are necessary for routing, transporting, measuring, and
billing traffic from the other Party's network and for delivering such traffic
to the other Party's network in the standard format compatible with BA's network
and to terminate the traffic it receives in that standard format to the proper
address on its network. Such facility shall be designed based upon the
description and forecasts provided under Sections 20.2 and 20.3 above. The
Parties are each solely responsible for participation in and compliance with
national network plans, including The National Network Security Plan and The
Emergency Preparedness Plan.

     20.6 Neither Party shall use any service related to or using any of the
Services provided in this Agreement in any manner that interferes with other
persons in the use of their service, prevents other persons from using their
service, or otherwise impairs the quality of service to other carriers or to
either Party's Customers, and either Party may discontinue or refuse service if
the other Party violates this provision. Upon such violation, either Party shall
provide the other Party notice, if practicable, at the earliest practicable
time.

     20.7 Each Party is solely responsible for the services it provides to its
Customers and to other Telecommunications Carriers.

("LERG") listings of CLLI codes assigned to its switches.

     20.11 Each Party shall use the LERG published by Bellcore or its successor
for obtaining routing information and shall provide all required information to
Bellcore for maintaining the LERG in a timely manner.

     20.12 Each Party shall program and update its own Central Office Switches
and End Office switches and network systems to recognize and route traffic to
and from the other





                                      -37-
<PAGE>   38
Party's assigned NXX codes. Except as mutually agreed or as otherwise expressly
defined in this Agreement, neither Party shall impose any fees or charges on the
other Party for such activities.

     20.13 At all times during the term of this Agreement, each Party shall keep
and maintain in force at each Party's expense all insurance required by law
(e.g., workers' compensation insurance) as well as general liability insurance
for personal injury or death to any one person, property damage resulting from
any one incident, automobile liability with coverage for bodily injury for
property damage. Upon request from the other Party, each Party shall provide to
the other Party evidence of such insurance (which may be provided through a
program of self insurance).

     20.14 End User Repair Calls. The Parties will employ the following
procedures for handling misdirected repair calls:

     20.14.1 In answering repair calls, neither Party shall make disparaging
remarks about each other, nor shall they use these repair calls as the basis for
internal referrals or to solicit customers to market services. Either Party will
respond with factual information in answering customer questions.

     20.14.2 Each Party will notify its customers as to the correct telephone
numbers to call in order to access its repair bureaus.

     20.14.3 To the extent possible, where the correct local exchange carrier
can be determined, misdirected repair calls to one Party will be immediately
referred to the other Party, as appropriate in a courteous manner, at no charge.

     20.14.4 The Parties will provide their respective repair contact numbers to
one another on a reciprocal basis.

21.0 TERM AND TERMINATION

     21.1 The initial term of this Agreement (the "Term") shall expire on
October 20, 2000. Absent the receipt by one Party of written notice from the
other Party at least sixty (60) days prior to the expiration of the Term to the

unable to reach agreement within six (6) months after the termination or
expiration of this Agreement, either Party has the right to submit this matter
to the Commission for resolution. Until a survivor Agreement is reached or the
Commission resolves this matter, whichever is sooner, the




                                      -38-

     24.1 The services, arrangements, Interconnection, Network Elements, terms
and conditions of this Agreement were mutually negotiated by the Parties as a
total arrangement and are intended to be non-severable, subject only to Section
28.14 of this Agreement.

25.0 INDEMNIFICATION

     25.1 Each Party (the "Indemnifying Party") shall indemnify and hold
harmless the other Party ("Indemnified Party") from and against loss, cost,
claim liability, damage, and expense (including reasonable attorney's fees) to
third Parties for:

         (1) damage to tangible personal property or for personal injury
proximately caused by the negligence or willful misconduct of the Indemnifying
Party, its employees, agents or contractors; and

         (2) claims for libel, slander, infringement of copyright arising from

         (3) claims for infringement of patents arising from combining the
Indemnified Party's facilities or services with, or the using of the Indemnified
Party's services or facilities in connection with, facilities of the
Indemnifying Party.

     Notwithstanding this indemnification provision or any other provision in
the Agreement, neither Party, nor its parent, subsidiaries, affiliates, agents,
servants, or employees shall be liable to the other for "Consequential Damages"
as that term is described in Section 26.3 below.

     25.2 The Indemnified Party will notify the Indemnifying Party promptly in
writing of any claims, lawsuits, or demands by third Parties for which the
Indemnified Party alleges that the Indemnifying Party is responsible under this
Section, and, if requested by the Indemnifying Party, will tender the defense of
such claim, lawsuit or demand.

         (1) In the event the Indemnifying Party does not promptly assume or
diligently pursue the defense of the tendered action, then the Indemnified Party
may proceed to defend or settle said action and the Indemnifying Party shall
hold harmless the Indemnified Party from any loss, cost liability, damage and
expense.

         (2) In the event the Party otherwise entitled to indemnification from
the other elects to decline such indemnification, then the Party making such an




                                      -39-
<PAGE>   40
election may, at its own expense, assume defense and settlement of the claim,
lawsuit or demand.

         (3) The Parties will cooperate in every reasonable manner with the
defense or settlement of any claim, demand, or lawsuit.

26.0 LIMITATION OF LIABILITY

     26.1 No liability shall attach to either Party, its parents, subsidiaries,
affiliates, agents, servants or employees for damages arising from errors,
mistakes, omissions, interruptions, or delays in the course of establishing,
furnishing, rearranging, moving, terminating, changing, or providing or failing

information with respect thereof or with respect to users of the services or
facilities) in the absence of gross negligence or willful misconduct.

     26.2 Except as otherwise provided in Section 25.0, no Party shall be liable

other Party for any indirect, special, consequential, incidental or punitive

has been advised of the possibility of such damages.

27.0 PERFORMANCE STANDARDS

     The Parties hereby agree that the performance standards and remedies
approved by the Department in the Consolidated Arbitrations, D.P.U. 96-73/74,

agree that this Agreement is satisfactory to them as an agreement under Section
251 of the Act. Each Party covenants and agrees to fully support approval of
this Agreement by the Department or the FCC under Section 252 of the Act without
modification. The Parties, however, reserve the right to seek regulatory relief
and otherwise seek redress from each other regarding performance and
implementation of this Agreement. In the event the Department or FCC rejects
this Agreement in whole or in part, the Parties agree to meet and negotiate in
good faith to arrive at a mutually acceptable modification of the rejected
portion(s).

     This Agreement shall be subject to change, modification or cancellation
based on any significant changes in FCC or state regulatory commission rules
which may impact the provision of service under this Agreement, or the rights
and obligations of the Parties under the Act. In the event such a modification
or cancellation is required or desired by a Party, the Parties agree to meet and
negotiate in good faith to arrive at mutually acceptable modifications or
cancellation of the Agreement; provided that such modified or cancelled
portion(s) shall not affect the validity of the remainder of this Agreement, if
any.

<PAGE>   41
authority to execute and deliver this Agreement and to perform its obligations

state, and local laws, rules, and regulations applicable to its performance
under this Agreement.

     29.3 Compliance with the Communications Assistance for Law Enforcement Act

facilities or services provided to the other Party under this Agreement comply
with CALEA. Each Party shall indemnify and hold the other Party harmless from
any and all penalties imposed upon the other Party for such noncompliance and
shall at the non-compliant Party's sole cost and expense, modify or replace any
equipment, facilities or services provided to the other Party under this
Agreement to ensure that such equipment, facilities and services fully comply
with CALEA.

     29.4 Independent Contractors. Neither this Agreement, nor any actions taken
by BA or TCG in compliance with this Agreement, shall be deemed to create an
agency or joint venture relationship between TCG and BA, or any relationship
other than that of purchaser and seller of services.

              Neither this Agreement, nor any actions taken by BA or TCG in
compliance with this Agreement, shall create a contractual, agency, or any other
type of relationship or third Party liability between BA and TCG's end users or
others.

     29.5 Force Majeure. Neither Party shall be liable for any delay or failure
in performance of any part of this Agreement from any cause beyond its control
and without its fault or negligence including, without limitation, acts of
nature, acts of civil or military authority, government regulations, embargoes,

weather conditions, inability to secure products or services of other persons or
transportation facilities or acts or omissions of transportation carriers
(collectively, a "Force Majeure Event").

              If any force majeure condition occurs, the Party delayed or unable
to perform shall give immediate notice to the other Party and shall take all
reasonable steps to correct the force majeure condition. During the pendency of
the Force Majeure, the duties of the Parties under this Agreement affected by
the Force Majeure condition shall be abated and shall resume without liability
thereafter.

     29.6     Confidentiality.

              29.6.1 Any information such as specifications, drawings, sketches,
business information, forecasts, models, samples, data, computer programs and
other software and documentation of one Party (a "Disclosing Party") that is
furnished or made available or otherwise disclosed to the other Party or any of
its employees, contractors, agents or Affiliates (its "Representatives" and with
a Party, a "Receiving Party") pursuant to this Agreement ("Proprietary
Information") shall be deemed the property of the Disclosing Party. Proprietary
Information, if written, shall be marked "Confidential" or "Proprietary" or by
other similar notice, and, if oral or visual, shall be confirmed in writing as
confidential by the Disclosing Party to the Receiving Party within ten (10) days
after disclosure. Unless Proprietary Information was previously known by the
Receiving Party free of any obligation to keep it confidential, or has been or
is subsequently made public by an act not attributable to the Receiving Party,
or is explicitly agreed in writing not to be regarded as confidential, it (i)
shall be held in confidence by each Receiving Party; (ii) shall be disclosed to
only those persons who have a need for it in connection with the provision of
services required to fulfill this Agreement and shall be used only for such
purposes; and (iii) may be used for other purposes only upon such terms and
conditions as may be mutually agreed to in advance of use in writing by the
Parties. Notwithstanding the foregoing sentence, a Receiving Party shall be
entitled to disclose or provide Proprietary Information as required by any
governmental authority or applicable law only in accordance with Section 29.6.2.

              29.6.2 If any Receiving Party is required by any governmental
authority or by applicable law to disclose any Proprietary Information, then
such Receiving Party shall provide the Disclosing Party with written notice of
such requirement as soon as possible and prior to such disclosure. The
Disclosing Party may then either seek appropriate protective relief from all or
part of such requirement or, if it fails to



                                      -41-
<PAGE>   42
successfully do so, it shall be deemed to have waived the Receiving Party's
compliance with Section 29.6 with respect to all or part of such requirement.
The Receiving Party shall use all commercially reasonable efforts to cooperate
with the Disclosing Party in attempting to obtain any protective relief which
such Disclosing Party chooses to obtain.

              29.6.3 In the event of the expiration or termination of this
Agreement for any reason whatsoever, each Party shall return to the other Party
or destroy all Proprietary Information and other documents, work papers and
other material (including all copies thereof) obtained from the other Party in
connection with this Agreement and shall use all reasonable efforts, including
instructing its employees and others who have had access to such information, to
keep confidential and not to use any such information, unless such information
is now, or is hereafter disclosed, through no act, omission or fault of such
Party, in any manner making it available to the general public.

     29.7 Governing Law. This Agreement is subject to the Act, and the effective
rules and regulations promulgated pursuant to the Act, and any other applicable
federal law, as well as the rules of the Commission. In all other respects, this
Agreement shall be governed by the domestic laws of the Commonwealth of
Massachusetts without reference to conflict of laws provisions.

     29.8 Taxes. Each Party purchasing services hereunder shall pay or otherwise
be responsible for all federal, state, or local sales, use, excise, gross
receipts, transaction or similar taxes, fees or surcharges levied against or
upon such purchasing Party (or the providing Party when such providing Party is
permitted to pass along to the purchasing Party such taxes, fees or surcharges),
except for any tax on either Party's corporate existence, status or income.
Whenever possible, these amounts shall be billed as a separate item on the
invoice. To the extent a sale is claimed to be for resale tax exemption, the
purchasing Party shall furnish the providing Party a proper resale tax exemption
certificate as authorized or required by statute or regulation by the
jurisdiction providing said resale tax exemption. Failure to timely provide said
resale tax exemption certificate will result in no exemption being available to
the purchasing Party.

     29.9 Non-Assignment. This Agreement shall be binding upon every subsidiary
and affiliate of either Party that is engaged in providing telephone exchange
and exchange access services in any territory within which BA is an Incumbent
Local Exchange Carrier as of the date of this Agreement (the "BA Territory"),
and shall continue to be binding upon all such entities regardless of any
subsequent change in their ownership. Each Party covenants that, if it sells or
otherwise transfers to a third Party its telephone exchange and exchange access
network facilities within the BA Territory, or any portion thereof, to a third
Party, it will require as a condition of such transfer that the transferee agree
to be bound by this Agreement with respect to services provided over the
transferred facilities. Except as provided in this paragraph, neither Party may
assign or transfer (whether by operation of law or otherwise) this Agreement (or
any rights or obligations hereunder) to a third Party without the prior written
consent of the other Party which consent will not be unreasonably withheld;
provided that either Party may assign this Agreement to a corporate Affiliate or
an entity under its common control or an entity acquiring all or substantially
all of its assets or equity by providing prior written notice to the other Party
of such assignment or transfer. Any attempted assignment or transfer that is not
permitted is void ab initio. Without limiting the generality of the foregoing,
this Agreement shall be binding upon and shall inure to the benefit of the
Parties' respective successors and assigns.

     29.10 Non-Waiver. Failure of either Party to insist on performance of any
term or condition of this Agreement or to exercise any right or privilege
hereunder shall not be construed as a continuing or future waiver of such term,
condition, right or privilege.

     29.11    Disputed Amounts.

              29.11.1 If any portion of an amount due to a Party (the "Billing
Party") under this Agreement is subject to a bona fide dispute between the
Parties, the Party billed (the "Non-Paying Party") shall within thirty (30) days
of its receipt of the invoice containing such disputed amount give notice to the
Billing Party of the amounts it disputes ("Disputed Amounts") and include in
such notice the specific details and reasons for disputing each item. The
Non-Paying Party shall pay when due (i) all undisputed amounts to the Billing
Party and (ii) all Disputed Amounts into an interest bearing escrow account with
a third Party escrow agent mutually agreed upon by the Parties.




                                      -42-
<PAGE>   43
              29.11.2 If the Parties are unable to resolve the issues related to
the Disputed Amounts in the normal course of business within ninety (90) days
after delivery to the Billing Party of notice of the Disputed Amounts, each of
the Parties shall appoint a designated representative who has authority to
settle the dispute and who is at a higher level of management than the persons
with direct responsibility for administration of this Agreement. The designated
representatives shall meet as often as they reasonably deem necessary in order
to discuss the dispute and negotiate in good faith in an effort to resolve such
dispute. The specific format for such discussions will be left to the discretion
of the designated representatives, however all reasonable requests for relevant
information made by one Party to the other Party shall be honored.

              29.11.3 If the Parties are unable to resolve issues related to the
Disputed Amounts within forty-five (45) days after the Parties' appointment of
designated representatives pursuant to Section 29.11.2, then either Party may
file a complaint with the Department to resolve such issues or proceed with any
other remedy pursuant to law or equity. The Department may direct release of any
or all funds (including any accrued interest) in the escrow account, plus
applicable late fees, to be paid to either Party.

              29.11.4 The Parties agree that all negotiations pursuant to this
Section 29.11 shall remain confidential and shall be treated as compromise and
settlement negotiations for purposes of the Federal Rules of Evidence and state
rules of evidence. Any undisputed amounts not paid when due shall accrue
interest from the date such amounts were due at the lesser of (i) one and
one-half percent (1-1/2%) per month or (ii) the highest rate of interest that
may be charged under applicable law.

     29.12 Notices. Notices given by one Party to the other Party under this
Agreement shall be in writing and shall be (i) delivered personally, (ii)
delivered by express delivery service, (iii) mailed, certified mail or first
class U.S. mail postage prepaid, return receipt requested or (iv) delivered by

releases, publicity matters or other promotional materials without such Party's

     29.15 No Third Party Beneficiaries; Disclaimer of Agency. This Agreement is
for the sole benefit of the Parties and their permitted assigns, and nothing
herein express or implied shall create or be construed to create any third-Party
beneficiary rights hereunder. Except for provisions herein expressly authorizing
a Party to act for another, nothing in this Agreement shall constitute a Party

appropriate optional flat rates to apply when local usage is handed off to BA at
an end office, with the intent of agreeing on mutually acceptable revisions no
later than 30 business days after the Effective Date.

     (C)      Formula for determining reciprocal compensation

Reciprocal compensation is a function of the point of interconnection. As a
facilities based provider. TCG may interconnect at either the end office (Meet
Point A) or through an access tandem (Meet Point B). The following formulas
reflect the appropriate rate components. In addition, Meet Point B can be
purchased under TCG's flat rate option.

            (1)  When interconnecting at an end office: Meet Point A rates apply

                     Meet Point A =   Local Switching Trunk Port per MOU
                                      +        Local Switching Usage per MOU
                                      =        Meet Point A

            (2) When interconnecting at an access tandem: Meet Point B
rates apply

                     Meet Point B =   Meet Point A
                                      +        Common Transport (Shared IOF)
                                      +        Tandem Common Trunk Port
                                      +        Tandem Common Trunk Port
                                      +        Tandem Usage
                                      =        Meet Point B

VII. 911/E911 Interconnection


         BA will bill Basic 911 traffic at the same rates it bills other local
traffic from TCG. For E911 service, TCG will pay a monthly rate based on the
number of TCG telephone numbers in the E911 database. The monthly rate will be
based on the BA E911 costs in Massachusetts as reported to the Department each
April and will be calculated by dividing the total E911 costs for Residence by
the total number of Residence telephone numbers in the data bases added to the
total E911 costs for Business divided by the total number of Business telephone
numbers in the data base. The total annual costs for Residence and Business will
be divided by 12 to develop the total monthly cost for Residence and Business.
The monthly bill to TCG will be calculated by multiplying the number of 
Residence TCG telephone numbers contained in the E911 data base times the
monthly rate per telephone number for Residence plus the number of business TCG
telephone numbers in the E911 data base times the monthly rate per telephone
number for Business.

     nonperformance by supplier(s) shall be on Lessee, and Lessor shall not be
     liable for specific performance of this Lease or for damages if, for any
     reason, any supplier delays or fails to fill or improperly fills an order.

     During the term of this Lease, the Equipment shall be located at the
     address specified in the Equipment Schedule and shall not be removed from
     that address without the prior written consent of Lessor. Lessee covenants
     and warrants that during the period that any Equipment is leased to Lessee,
     or its successors or assigns, the Equipment will at all times be used and
     operated in compliance with the laws of the jurisdictions in which it is
     located, and in compliance with all acts, rules, regulations, and orders of
     any commission, board or other legislative, administrative, or judicial
     body or officer having power to regulate or supervise the use or operation
     of the Equipment. Lessee shall not install or use the Equipment in such
     manner or in such circumstances that any part of the Equipment is deemed to
     be an accession to other personal property or deemed to be real property or
     a fixture thereon.

5.   ERRORS IN ESTIMATED COST: As used herein, "Total Cost" means the cost to
     Lessor of purchasing and delivering the Equipment to Lessee, including
     taxes and transportation and other charges. The amount of each rental
     payment set forth on the Equipment Schedule is based on the Total Cost
     initially set forth which is an estimate, and each shall be adjusted
     proportionally if the actual cost of the Equipment differs from said
     estimate. Lessee hereby authorizes Lessor to correct the figures set forth
     on the Equipment Schedule(s) when the actual cost is known, and to add to
     the amount of each rental payment any sales, use or other tax that may be
     imposed on or measured by rental payments. If the actual cost of the
     Equipment differs from the estimated cost by more than [**] however, either
     party at its option may terminate the Lease with respect to the Equipment
     as to subsequent obligations by giving written notice to the other party
     within fifteen (15) days after receiving notice of the actual cost or the
     corrected rentals and Lessee shall reimburse and indemnify Lessor for any
     existing obligation and/or expenses incurred by Lessor such as but not
     limited to, open purchase orders and progress payments made to supplier(s).

6.   INSPECTION: Lessee shall, whenever requested, advise Lessor of the exact
     location and condition of the Equipment and shall give Lessor immediate
     notice of any attachment or other judicial processes, liens or encumbrances
     affecting the Equipment and indemnify and save Lessor harmless from any
     loss or damage caused thereby. Lessor may for the purpose of inspection, at
     all reasonable business hours, enter any building or place where the
     Equipment is located. Lessor shall be entitled to review Lessee's
     maintenance records relating to the Equipment.

7.   PRESERVATION OF LESSEE'S EXISTENCE AND BUSINESS:
     (a) Lessee will preserve and keep in full force and effect Lessee's
     existence, rights, licenses and franchises and those of any Subsidiaries,
     necessary and material to Lessee's and Subsidiaries' operations taken as a
     whole.
     (b) Lessee will not make or permit to be made any material change in the
     character of Lessee's business or operations.

8.   FINANCIAL INFORMATION AND REPORTING:
     (a) Lessee shall annually, within ninety (90) days after the close of
     Lessee's fiscal year, furnish to Lessor, financial statements of Lessee
     (including a balance sheet as of the close of such year and statements of
     income, changes in financial condition and shareholder's equity for such
     year) prepared in accordance with generally accepted accounting principles
     and certified by Lessee's



                                        2

<PAGE>   3
     independent public accountants. Lessee shall also provide quarterly
     financial statements of Lessee similarly prepared for each of the first
     three quarters of each fiscal year, which shall be certified (subject to
     normal year-end adjustments) by Lessee's chief financial officer and
     furnished to Lessor within sixty (60) days following the end of the
     quarter.
     (b) Lessee will furnish Lessor with any and all information regarding
     Lessee's business, condition or operations, financial or otherwise which
     Lessee furnishes to any other creditor. This information shall be furnished
     to Lessor at the same time it is furnished to that creditor.
     (c) Lessee will immediately furnish Lessor with such further information
     regarding Lessee's business, condition, property, assets or operations,
     financial or otherwise, as Lessor may from time to time reasonably request,
     all prepared in form and detail satisfactory to Lessor.
     (d) Lessee will at all times maintain true and complete records and books
     of account including, without limiting the generality of the foregoing,
     appropriate reserves for possible losses and liabilities, all in accordance
     with generally accepted accounting principles consistently applied.
     (e) Lessee shall permit, and cause any Subsidiary to permit,
     representatives of Lessor (i) to visit and inspect any of the properties of
     Lessee or any Subsidiary (ii) to examine its or their corporate or
     partnership books and records, (iii) to make extracts or copies of such
     books and records, and (iv) to discuss its or their affairs, finances and
     accounts with its or their officers or partners, as applicable. The
     foregoing may be done at any time within regular business hours.
     (f) Lessee will promptly notify Lessor in writing of the commencement of
     any litigation to which Lessee or any of its affiliates may be a party
     (except for litigation in which Lessee's (or the affiliate's) contingent
     liability is fully covered by insurance) which, if decided adversely to
     Lessee would adversely affect or impair the title of Lessor to the
     Equipment or which, if decided adversely to Lessee would materially
     adversely affect the business operations or financial condition of Lessee.
     In addition, Lessee will immediately notify Lessor, in writing, of any
     judgment against Lessee if such judgment would have the effect described in
     the preceding sentence.

9.   PAYMENT OF TAXES, DEBTS AND OBLIGATIONS:
     (a) Lessee shall pay all taxes, assessments, fees, charges, penalties and
     fines imposed upon the Equipment and/or arising out of the lease, use,
     possession or operation thereof and whether levied or assessed against
     Lessee or against Lessor. All taxes, fees and similar charges imposed on
     the ownership, possession or use of the Equipment during the term of this
     Lease shall be paid by Lessee. In case of failure of Lessee to pay said
     taxes, fees and similar charges, Lessor may pay the same, and the amount
     thereof shall be payable by Lessee as additional rent with the next rental
     payment. (b) Lessee will cause to be paid and discharged all its
     obligations when due and all lawful taxes, assessments and governmental
     charges or levies imposed upon Lessee or any Subsidiary, or upon any
     property, real, personal or mixed, belonging to Lessee or any Subsidiaries,
     or upon any part thereof, before the same shall become in default, as well
     as all lawful claims for labor, materials and supplies which, if unpaid,
     might become a lien or charge upon the property or any part of it.
     Notwithstanding the previous sentence, neither Lessee nor any Subsidiary
     shall be required to cause to be paid and discharged any obligation, tax,
     assessment, charge, levy or claim so long as its validity is contested in
     the normal course of business and in good faith by appropriate and timely
     proceedings and Lessee or any Subsidiary, as the case may be, sets aside on
     its books adequate reserves with respect to each tax, assessment, charge,
     levy or claim so contested, nor shall Lessee nor any Subsidiary be required
     to pay or discharge any trade Indebtedness which is not past its stated due
     date by more than thirty (30) days.

10.  MAINTENANCE: Lessee shall enter into and maintain in force throughout the
     term of this Lease a maintenance agreement with the equipment
     manufacturers), or such other qualified maintenance organization as Lessee
     may select, covering maintenance of the Equipment. Lessee will cause the
     Equipment to be kept in good working order, repair and maintenance in
     accordance with the provisions of each maintenance agreement and will make
     all necessary adjustments and repairs to the Equipment. Any parts installed
     or replacements made by Lessee to any Item pursuant to



                                        3

<PAGE>   4
     Lessee's obligation to maintain the Equipment shall be considered
     accessions and title thereto shall immediately vest in Lessor. Each
     manufacturer or service organization is hereby authorized to accept the
     directions of Lessee with respect thereto. Lessee shall allow the
     manufacturer(s) or service organization full and free access to the
     Equipment. All maintenance and service charges, whether under a maintenance
     agreement or otherwise, shall be borne by Lessee, including the expenses,
     if any, of a manufacturer's or service organization's customer engineer
     charged in connection with maintenance and repair services. Lessee
     covenants that the Equipment will at all times be used and operated in
     accordance with each manufacturer's instructions and in compliance with any
     restriction contained in each manufacturer's warranties regarding the
     Equipment.

11.  ALTERATIONS AND ATTACHMENTS: Upon prior written notice to Lessor, Lessee
     may, at its own expense, make alterations in or add attachments to the
     Equipment provided any alteration or attachment shall not interfere with
     the normal operation of the Equipment. The manufacturer may incorporate
     engineering changes or make temporary alterations to the Equipment upon
     request by Lessee. All such alterations and attachments, unless Lessor
     shall otherwise agree in writing, shall be removed by Lessee and the
     Equipment restored to its original condition, reasonable wear and tear
     excepted, upon termination of this Lease. If the alteration or attachment
     interferes with the normal and satisfactory operation or maintenance of the
     Equipment in a manner as to increase the cost of maintenance of the
     Equipment, or create a safety hazard, Lessee shall promptly remove the
     alteration or attachment and restore the Equipment to its normal condition.

12.  INSURANCE; NOTICE OF ACCIDENT:
     (a) At its sole expense, Lessee shall secure and maintain in full force and
     effect throughout the term of all Equipment Schedules and any extensions or
     renewals thereof, insurance against all risks including, but not limited
     to, theft, damage, or destruction of the Equipment in an amount equal to
     the aggregate Total Cost of all Equipment Schedules written in the broadest
     form available on usual commercial terms and with carriers acceptable to
     Lessor. Lessee shall also maintain public liability insurance satisfactory
     to Lessor and with at least the minimum limits as set forth in the
     Equipment Schedule.
     (b) Upon execution of the Certificate of Acceptance, Lessee shall deliver
     the policy or policies or duplicates or certificates thereof, to Lessor.
     Lessee shall maintain a loss payable endorsement on all such policies in
     favor of Lessor and its successors and assigns and shall afford to Lessor
     and its successors and assigns such additional protection as Lessor and its
     successors and assigns shall reasonably require. All such insurance
     policies shall name Lessor, its successors and assigns, as additional
     insureds and expressly provide that any obligations imposed upon the
     insureds (including, without limitation, the obligation to pay premiums)
     shall be the obligation solely of Lessee and not the obligations of Lessor,
     its successors and assigns. Each policy shall expressly provide that (1)
     the insurance as to Lessor and its successors and assigns shall not be
     invalidated by any act, omission or neglect of Lessee, (2) the same may not
     be canceled, modified or allowed to lapse (for failure to renew or
     otherwise) without at least thirty (30) days prior written notice to Lessor
     or its successors and assigns, and (3) the insurance shall be primary,
     without right or contribution of any other insurance carried by or on
     behalf of Lessor with respect to its interests.

     In the event that any policies insuring against liability risks described
     above shall now or hereafter provide coverage on a "claims made" basis,
     Lessee shall continue to maintain such policies in effect for a period of
     not less than three years after the expiration of the Lease term of any
     Equipment Schedule.

     (c) Lessor and its successors and assigns may apply the proceeds of
     insurance to replace or repair the Equipment and/or to satisfy Lessee's
     obligations hereunder, as determined in Lessor's sole discretion. If Lessee
     fails to pay when due any insurance premium for any policy written
     hereunder, then Lessor may make such premium payment and add the amount
     thereof to the next



                                        4

<PAGE>   5
     rent payment, and such premium amounts shall become rent. Lessee appoints
     Lessor as Lessee's attorney-in-fact to make any claim for, to receive
     payment for and to execute and endorse any documents, checks or other
     instruments in payment for loss, theft or damage under any such insurance
     policy. Lessor shall be under no duty to ascertain the existence of any
     insurance coverage or to examine any certificate of insurance or other
     evidence of insurance coverage or to advise Lessee in the event the
     insurance coverage does not comply with the requirements of this Agreement.
     Lessee will promptly notify the appropriate insurer, Lessor and any
     assignee, of an accident or occurrence which may become the basis of a
     claim against the insured. In connection with any claim against Lessor
     and/or Lessee arising out of the ownership, operation, maintenance and use
     of the Equipment, Lessee agrees to cooperate with Lessor in defending
     against such claims, including making Lessee's employees available to
     Lessor without charge.
     (d) Lessee will maintain, and cause any Subsidiaries to maintain, insurance
     from duly licensed and responsible insurers on all property of Lessee and
     any Subsidiaries to its full insurable value, except to the extent limited
     by applicable insurance law. This insurance shall be against risks of fire
     and all other risks as fall within "extended coverage" as that term is
     generally understood in the insurance industry. Lessee shall also maintain,
     and cause any Subsidiaries to maintain, additional insurance in such
     amounts and against such risks, including, without limitation, product
     liability, personal injury, property damage, and workers' compensation, as
     is usually carried by owners of similar businesses of similar size and
     profits or as Lessor may reasonably require.

13.  INDEMNIFICATION: To the fullest extent permitted by law, Lessor, its
     officers, employees, agents, successors and assigns, shall not be liable to
     Lessee for, and Lessee shall indemnify and hold Lessor, its officers,
     employees, agents, successors and assigns, harmless with respect to any
     third-party from any liability (including liability for Lessee negligence),
     claim, loss, damage or expense (including litigation expense) of any kind
     or nature arising out of this Lease, or the transactions contemplated in
     this Lease, including, but not limited to: (a) the inadequacy of any Item
     of Equipment for any purpose; (b) any deficiency or defect in any Item of
     Equipment; (c) the use or performance or maintenance of any Item of
     Equipment; (d) any interruption or loss of service, use or performance of
     any Item of Equipment; or (e) any loss of business or other consequential
     damage whether or not resulting from any of the foregoing. IN PARTICULAR,
     LESSOR AND ITS SUCCESSORS AND ASSIGNS SHALL NOT BE LIABLE FOR INJURIES TO
     PERSONS OR DAMAGE TO ANY ITEM OF EQUIPMENT OR OTHER PROPERTY UNDER ANY
     THEORY OF STRICT LIABILITY, AND LESSEE SHALL INDEMNIFY AND SAVE LESSOR AND
     ITS SUCCESSORS AND ASSIGNS HARMLESS FROM ANY SUCH LIABILITY AND ALL COSTS
     AND EXPENSES IN DEFENDING THE SAME. This obligation to indemnify shall
     apply from the date of the execution of the Equipment Schedule out of which
     the claim arises, notwithstanding that the lease term may not have
     commenced. All of Lessor's and its successors and assigns rights under this
     section shall survive the termination of this Lease. However, Lessee shall
     not be required to indemnify Lessor or its successors or assigns for claims
     arising from events which occur after the Equipment has been redelivered to
     Lessor, its successors or assigns.

14.  RISK OF LOSS:
     (a) Lessee hereby assumes and shall bear the entire risk of loss, theft,
     damage and destruction of the Equipment, whether partial or complete, from
     any cause whatsoever. No loss, theft, damage or destruction of Equipment
     shall relieve Lessee of the obligation to pay rent or any other obligation
     of this Lease, and, except as provided below, this Lease shall remain in
     full force and effect. Lessee shall promptly notify Lessor in writing of
     any such loss, theft, damage or destruction of the Equipment. Lessor shall
     not be liable to Lessee for any loss, damage or expense of any kind or
     nature, caused directly or indirectly by any Item of Equipment or by the
     use, maintenance, repair, failure, destruction or damage of any Equipment.
     (b) In the event of damage of any kind whatsoever to the Equipment (unless
     the same is damaged



                                        5

       and Exchange Commission. Asterisks denote omissions.


     beyond repair), Lessee, at the option of Lessor, shall at Lessee's expense
     (i) place the same in good repair, condition and working order, or (ii)
     replace the same with like Equipment of the same or a later model, and in
     good repair, condition and working order and provide Lessor good and valid
     title thereto.
     (c) In the event that the Equipment is lost, stolen, destroyed or damage
     beyond repair (any such event is referred to as an "Event of Loss"),
     Lessee, at the option of Lessor, shall (i) at Lessee's expense replace the
     same with like Equipment of the same or a later model, in good repair,
     condition and working order and provide Lessor good and valid title thereto
     or (ii) pay to Lessor an amount equal to the unpaid balance of the rent and
     any other sums then due or past due, plus the Stipulated Loss Value
     attributable to the Equipment (as set forth on Attachment I to the
     Equipment Schedule) calculated on the rental payment date immediately
     preceding the date of the loss (this option (ii) shall only be applicable
     if a Stipulated Loss Value table is referenced in the Equipment Schedule),
     or (iii) pay to Lessor an amount equal to the unpaid balance of the rent
     and any other sums then due, plus the balance of any remaining rents
     (discounted at the rate of [**] percent per annum) attributable to the
     Equipment during the term and extension thereof, if any, of this Lease.
     Upon such payment Lessee's obligation to pay further rent for such
     Equipment shall cease, and Lessee thereupon shall become entitled to the
     Equipment paid for "as-is-where-is", without recourse or warranty, express
     or implied, with respect to any matter whatsoever.
     (d) To the extent of Lessee's expense actually incurred to repair or
     replace the Equipment or of Lessee's payment to Lessor for the loss, theft,
     damage or destruction of any Item of Equipment, Lessee shall then be
     entitled to receive from Lessor any insurance or recovery received by
     Lessor in connection with such loss, theft, damage or destruction, and any
     amount of insurance or recovery received by Lessor in excess of Lessee's
     expenses actually incurred or paid to Lessor shall belong to Lessor. Lessor
     shall not be obligated to deliver to Lessee any insurance or recovery
     received by Lessor in connection with any loss, theft, damage or
     destruction until Lessee has provided Lessor with such documents as Lessor
     shall deem necessary or desirable for purposes of evidencing that the
     Equipment has been repaired or replaced in accordance with this Section 14.

15.  OWNERSHIP OF EQUIPMENT: The Equipment shall at all times remain personal
     property, and title thereto shall remain solely in Lessor. The Equipment
     may be removed by Lessor at any time after termination of this Lease.
     Lessee shall affix tags, decals or plates to the Equipment indicating
     Lessor's ownership, which type of tag, decal or plate and location may be
     specified by Lessor, and Lessee shall not permit their removal or
     concealment. Lessee shall cause each Item of Equipment to be kept numbered
     with the serial number specified in the Certificate of Acceptance. Lessee
     shall, at its own expense, protect and defend Lessor's title in the
     Equipment against all claims and liens of Lessee's creditors and keep the
     Equipment free and clear of all claims, liens and encumbrances except those
     resulting from the agreements or acts of Lessor. At Lessor's request Lessee
     shall obtain and record such instruments and take such steps as may be
     necessary to prevent any entity from acquiring any rights in the Equipment
     by reason of the Equipment being claimed as or deemed as real property.

     In the event this Agreement or any Equipment Schedule thereto shall be
     adjudged or determined not to be a Lease, then Lessor's retention of title
     to the Equipment shall be construed to be, and Lessee does hereby grant to
     Lessor, a security interest in the Equipment, insurance covering the
     Equipment and all of the proceeds of the foregoing.

16.  ASSIGNMENT: Neither this Lease nor Lessee's rights hereunder shall be
     assignable in whole or in part by Lessee except with Lessor's prior written
     consent, and the provisions hereof shall bind any permitted successors and
     assigns of Lessee. Lessor shall have the right to assign this Lease or any
     part thereof. If Lessor assigns the rentals reserved herein or all or any
     of Lessor's other rights hereunder, or amounts equal thereto, the right of
     the Assignee to receive the rentals as well as any other right of the
     Assignee shall not be subject to any defense, setoff, counterclaim, or
     recoupment



                                        6

<PAGE>   7
     which may arise out of any breach or obligation of Lessor in connection
     herewith or by reason of any other indebtedness or liability at any time
     owing by Lessor to Lessee. All rentals due hereunder shall be payable to
     the Assignee by Lessee whether or not this Lease is terminated by operation
     of law or otherwise, including without limitation, termination arising out
     of bankruptcy, reorganization or similar proceedings involving Lessor. On
     receipt of notification of such assignment, Lessee, subject to its rights
     hereunder, shall become the pledgeholder of the Equipment for and on behalf
     of the Assignee and will relinquish possession thereof only to the Assignee
     or pursuant to its written order. Lessee, on receiving notice of any such
     assignment, shall abide thereby and make payment as may therein be
     directed. Following any such assignment the term "Lessor" shall be deemed
     to include or refer to Lessor's Assignee, provided that no such Assignee
     shall be deemed to assume any obligation or duty imposed upon Lessor
     hereunder, and Lessee shall look only to Lessor for performance thereof.
     Lessee is further directed that after assignment of a Lease only Assignee
     shall have the right or power to compromise, settle, extend or otherwise
     negotiate the terms of payment under that Lease.

17.  SECURITY INTEREST: Where appropriate, Lessor shall file all necessary
     documents, including UCC financing statements, in connection with this
     Lease so as to perfect Lessor's security interest under the Lease. Lessee
     shall execute and deliver to Lessor such documents (including UCC financing
     statements) as Lessor shall deem necessary or desirable for purposes of
     evidencing, protecting or recording the rights and interest of Lessor in
     the Equipment or this Lease and in furtherance of the performance of the
     terms and conditions of this Lease. All reasonable expenses (including UCC
     search and filing fees) related thereto shall be paid by Lessee. Lessee
     hereby irrevocably appoints Lessor as its lawful attorney and agent to
     execute UCC financing statements on Lessee's behalf and hereby authorizes
     Lessor to file, at Lessee's expense, such UCC financing statements in any
     appropriate public office.

18.  DISPOSITION: At the expiration or termination of this Lease by lapse of
     time, or otherwise, Lessee shall return the Equipment to Lessor or its
     designee at a location designated by Lessor within New York State, with
     transportation charges (including in-transit insurance), prepaid by Lessee,
     in the same condition as when received by Lessee, ordinary wear and tear
     alone excepted, and free of any lien created or suffered by Lessee. To the
     extent the Lease does not terminate at the end of the Lease term thereof,
     or the Equipment is not returned to Lessor or its designee, and other
     rental amounts are not specified therein or mutually agreed to in writing,
     then the same amount of rent shall continue to be due and payable by Lessee
     until the Equipment is returned to Lessor or its designee. Lessee shall
     remain responsible to maintain in full force and effect insurance in
     accordance with paragraph 12 of this Agreement.

19.  EVENTS OF DEFAULT AND LESSOR'S REMEDIES:
     (a) Each of the following events shall constitute an event of default
     ("Event of Default") hereunder: (i) Lessee fails to pay any rent or other
     amount due hereunder within ten (10) days after the same is due and
     payable; or (ii) Lessee fails to perform any other obligation or observe
     any condition of this Lease required to be performed or observed by Lessee;
     or (iii) any representation, warranty or statement made in writing to
     Lessor by Lessee (or any guarantor of Lessee's obligations under this
     Agreement) in connection with the transactions contemplated under this
     Lease shall have been false in any material respect when made; or (iv)
     Lessee attempts to sell, transfer, encumber, part with possession of,
     assign or sublet (except as expressly permitted by the provisions hereof)
     any Item of Equipment; or (v) Lessee fails to insure (pursuant to Section
     12 hereof) any Item of Equipment; or (vi) Lessee fails to deliver to Lessor
     any documents required by Lessor under the Lease; or (vii) Lessee (or any
     guarantor of Lessee's obligations under this Agreement) is in default under
     any other agreement with Lessor or any of its affiliates; or (viii) Lessee
     ceases doing business as a going concern; or (ix) Lessee (or any guarantor
     of Lessee's obligations under this Agreement) shall consolidate with or
     merge into any other entity, or convey, transfer or lease substantially all
     of its

       and Exchange Commission. Asterisks denote omissions.

     assets to any other entity; or (x) the corporate existence of Lessee (or
     any guarantor of Lessee's obligations under this Agreement) shall
     terminate; or (xi) any of Lessee's issued and outstanding shares of capital
     stock are sold, assigned, pledged, transferred, exchanged in a corporate
     reorganization or otherwise disposed of or new shares of such stock are
     issued and such sale, assignment, pledge, transfer, exchange, issuance or

     this Lease (hereinafter "Unpaid Rent"); and/or (iii) to take possession of
     any or all Item(s) of Equipment without demand or notice wherever the same
     may be located without any court order or other process of law. Upon taking
     possession of any or all Item(s) of Equipment, Lessor at its option may (i)
     lease the repossessed Equipment to any third party on such terms and
     conditions as Lessor may determine, or (ii) sell the Equipment or any part
     thereof at public auction or at private sale. In the event Lessor re-lets
     the repossessed Equipment, then Lessor shall credit against the Unpaid Rent
     the present value of the aggregate of the rent to be received from the
     re-lease during the remaining term of the applicable Equipment Schedules
     (discounted at a rate equal to the sum of the prime interest rate in effect
     at The Chase Manhattan Bank, on the date such re-lease is entered into
     [**]). In the event Lessor sells the repossessed Equipment, then Lessor
     shall credit all amounts received from the sale, less expenses incurred in
     connection therewith, to the Unpaid Rent due. Lessee hereby agrees to
     peaceably deliver the Equipment to Lessor upon demand after an Event of
     Default is declared by Lessor; Lessee waives any and all damages occasioned
     by such taking possession. Any such taking of possession shall not
     constitute a termination of this Lease and shall not relieve Lessee of its
     original obligation hereunder unless Lessor expressly so notifies Lessee in
     writing.
     (c) Should any proceeding be instituted by Lessor to recover any monies due
     and/or to become due hereunder and/or for the possession of the Equipment,
     Lessee shall pay a reasonable sum as attorney's fees and collection agency
     fees, court costs and repossession expenses.

     The exercise, or the beginning of exercise by the Lessor of any one or more
     of such remedies described above shall not constitute the exclusive
     election of such remedies and shall not preclude the simultaneous or later
     exercise by Lessor of any or all of such other remedies.

20.  LESSEE'S AND LESSOR'S WARRANTIES: (a) Lessee hereby warrants and represents

     to a Subsidiary of Lessee or to any entity or person designated by Lessee,

     to, the terms of this Lease shall be effective or binding on Lessor unless
     the same is in writing and signed by Lessor (except if the Lease term is

     (a) Lessee will immediately notify Lessor in writing with full details if
     (i) any event occurs or any condition exists which constitutes, or which

     an Event of Default under Part 19, or which might materially and adversely
     affect the financial condition or operations of Lessee or of any Subsidiary
     or (ii) any representation or warranty made in the Master Lease Agreement
     or in any writing related to it may for any reason cease in any material
     respect to be true and complete.

     been furnished by written notice from the party to whom notice is sent.

24.  TIME OF ESSENCE; ENTIRE AGREEMENT; WAIVER; SURVIVAL OF TERMS: Time is of
     the essence of this Lease. This Lease constitutes the entire agreement
     between the parties and shall be binding upon the parties and their
     respective successors or assigns, and shall only be amended by a written
     instrument signed by Lessor and Lessee. Any waiver of the performance of
     any of the terms, conditions or covenants hereof by either party shall not
     be construed as thereafter waiving any such terms, conditions or covenants,
     but the same shall remain in full force and effect, as if no such waiver
     has occurred. Lessee's obligations and liabilities under this Lease shall
     not be affected by the expiration or earlier termination of this Lease.

     INCLUDING THE CONDITION OF THE EQUIPMENT, ITS MERCHANTABILITY OR FITNESS
     FOR ANY PARTICULAR PURPOSE, AND, AS TO LESSEE, LESSOR LEASES THE EQUIPMENT

     CONTINUING, LESSOR WILL NOT INTERFERE WITH THE LESSEE'S USE AND POSSESSION

     claim on account thereof solely against the manufacturer or supplier.
     Lessor hereby agrees to assign to Lessee, solely for the purpose of making
     and prosecuting any such claim, all of the rights which Lessor has against
     such manufacturer or supplier for breach of warranty or other
     representation respecting the Equipment to the extent the same are
     assignable.

28.  LESSOR'S RIGHT TO CURE: Upon Lessee's failure to perform any of its duties
     under a Lease, Lessor may, but shall not be obligated to, perform any or
     all such duties, and Lessee shall pay an amount equal to the expenses
     thereof to Lessor forthwith upon demand by Lessor. No such performance of
     any or all such duties by Lessor shall be deemed to cure any Event of
     Default of Lessee.

29.  ADDITIONAL ASSURANCES: If Lessor shall request, Lessee shall execute and
     deliver to Lessor such documents as Lessor shall reasonably deem necessary
     or desirable.

     on the Equipment Schedule, Certificate of Acceptance, UCC- 1 financing
     statements covering the Equipment and all other related documents. Lessor

                               TAX INDEMNIFICATION


        This Rider is appended to and made part of Equipment Schedule No. 1,
dated AUGUST 8, 1997 (the "Lease"), between Chase Equipment Leasing, Inc.
("Lessor") and NETWORK PLUS, INC. ("Lessee").

        This Lease has been entered into on the basis that Lessor shall be
entitled to such deductions, credits and other tax benefits as are provided by
federal, state and local law to an owner of property ("Tax Benefits") including,
without limitation Modified Accelerated Cost Recovery deductions on the
Equipment allowed under Section 168 of the Internal Revenue Code of 1986, as
amended (the "Code") for "5 year property".

        If Lessor shall lose, shall not have or shall lose the right to claim,
or if there shall be disallowed or recaptured with respect to Lessor, all or any
portion of the Tax Benefits as are provided to an owner of property with respect
to any Equipment ("Loss") then on the next succeeding rental payment date after
written notice to Lessee by Lessor that a Loss has occurred, or if there be no
such date, thirty days following such notice, Lessee shall pay Lessor an amount
which, in the reasonable opinion of Lessor and after deduction of all taxes
required to be paid by Lessor with respect to the receipt of such amount, will
cause the Lessor's net after-tax return over the term of the Lease in respect of
such Equipment to equal the net after-tax return that would have been available
if Lessor had been entitled to the utilization of all of the Tax Benefits.

        For purposes of this Rider, a Loss shall occur upon the earliest of (i)
the happening of any event (such as disposition or change in use of any
Equipment) which may cause such Loss, (ii) the payment by Lessor to the Internal
Revenue Service of the tax increase resulting from such Loss, or (iii) the
adjustment of the tax return of Lessor to reflect such Loss. Lessor shall not be
entitled to a payment under this Rider on account of any Loss due solely to one
or more of the following events: (aa) a failure of Lessor to claim timely or
properly the Tax Benefits for the Equipment in the tax return of the Lessor;
(bb) a disqualifying change in the nature of the Lessor's business or
liquidation thereof; (cc) a Foreclosure by any person holding through Lessor of
a lien on the Equipment, which foreclosure results solely from an act of Lessor;
or (dd) the failure of Lessor to have sufficient taxable income or tax liability
to utilize such Tax Benefits.

        All of the Lessor's rights and privileges arising from the indemnities
contained in this Rider shall survive the expiration or other termination of
this Lease.

        For the purposes of this Rider the term "Lessor" shall include any
affiliated group (within the meaning of Section 1504 of the Code) of which
Lessor is a member for any year in which a consolidated income tax return is
filed for such affiliated group.

        IN WITNESS WHEREOF, the parties have executed this Rider.

                                     RIDER I
                               TAX INDEMNIFICATION




        This Rider is appended to and made part of Equipment Schedule No.2,
dated OCTOBER 21, 1997(the "Lease"), between Chase Equipment Leasing, Inc.
("Lessor") and NETWORK PLUS, INC. ("Lessee").

        This Lease has been entered into on the basis that Lessor shall be
entitled to such deductions, credits and other tax benefits as are provided by
federal, state and local law to an owner of property ("Tax Benefits") including,
without limitation Modified Accelerated Cost Recovery deductions on the
Equipment allowed under Section 168 of the Internal Revenue Code of 1986, as
amended (the "Code") for "5 year property".

        If Lessor shall lose, shall not have or shall lose the right to claim,
or if there shall be disallowed or recaptured with respect to Lessor, all or any
portion of the Tax Benefits as are provided to an owner of property with respect
to any Equipment ("Loss") then on the next succeeding rental payment date after
written notice to Lessee by Lessor that a Loss has occurred, or if there be no
such date, thirty days following such notice, Lessee shall pay Lessor an amount
which, in the reasonable opinion of Lessor and after deduction of all taxes
required to be paid by Lessor with respect to the receipt of such amount, will
cause the Lessor's net after-tax return over the term of the Lease in respect of
such Equipment to equal the net after-tax return that would have been available
if Lessor had been entitled to the utilization of all of the Tax .Benefits.

        For purposes of this Rider, a Loss shall occur upon the earliest of (i)
the happening of any event (such as disposition or change in use of any
Equipment) which may cause such Loss, (ii) the payment by Lessor to the Internal
Revenue Service of the tax increase resulting from such Loss, or (iii) the
adjustment of the tax return of Lessor to reflect such Loss. Lessor shall not be
entitled to a payment under this Rider on account of any Loss due solely to one
or more of the following events: (aa) a failure of Lessor to claim timely or
properly the Tax Benefits for the Equipment in the tax return of the Lessor;
(bb) a disqualifying change in the nature of the Lessor's business or
liquidation thereof, (cc) a foreclosure by any person holding through Lessor of
a lien on the Equipment, which foreclosure results solely from an act of Lessor;
or (dd) the failure of Lessor to have sufficient taxable income or tax liability
to utilize such Tax Benefits.

        All of the Lessor's rights and privileges arising from the indemnities
contained in this Rider shall survive the expiration or other termination of
this Lease.

        For the purposes of this Rider the term "Lessor" shall include any
affiliated group (within the meaning of Section 1504 of the Code) of which
Lessor is a member for any year in which a consolidated income tax return is
filed for such affiliated group.

IN WITNESS WHEREOF, the parties have executed this Rider.

                            OPTIONS AT LEASE MATURITY





        The following provisions are hereby agreed upon and made a part of the
above-referenced Lease. Capitalized terms used herein but not defined shall have
the meanings attributable to them in the Equipment Schedule or the Master Lease
Agreement incorporated thereunder. Provided LESSEE has faithfully performed and

contrary, at the expiration of the Periodic Rental Term hereof, at its option,
LESSEE may purchase from LESSOR, and LESSOR shall sell to LESSEE, not less than
all of the Equipment described on Equipment Schedule No. 2 to Master Lease
Agreement dated AUGUST 8, 1997 "as-is, where-is," without recourse or warranty

provided, not to exceed 12% of the original cost of the Equipment, plus any
sales or use taxes, and other taxes (except taxes measured by the income of
LESSOR), fees or charges applicable to the sale and delivery of the Equipment.

        a.   NOTICE. LESSEE shall exercise option by giving LESSOR written
        notice, at least ninety (90) days prior to the expiration of the
        Periodic Rental Term, of LESSEE's intent to purchase the Equipment.

        b.   FAIR MARKET VALUE. The 'Fair Market Value" of the Equipment shall
        be an amount mutually agreed upon by LESSOR and LESSEE; provided that if
        LESSOR and LESSEE are unable to agree upon the Fair Market Value of the
        Equipment or Items thereof, within 30 days after receipt by LESSOR of
        LESSEE's notice of election to exercise this purchase option, the Fair
        Market Value shall be determined by an appraiser selected by mutual
        agreement of the LESSOR and LESSEE. The fees and costs of the appraisal
        shall be shared equally by LESSOR and LESSEE.

        c.   PAYMENT. LESSEE shall pay to LESSOR the Purchase Price in full on
        or before the expiration of the Periodic Rental Term of the Lease.

        d.   TITLE. All of LESSOR's rights, title and interest to and in the
        Equipment shall pass to LESSEE upon receipt by LESSOR of the Purchase
        Price in full.

        e.   OTHER TERMS AND CONDITIONS. If LESSEE has exercised its option to
        purchase the Equipment and if the Purchase Price in full is not received
        by LESSOR on or before the expiration of the Periodic Rental Term,
        LESSEE hereby agrees to be bound by and to carry out each of the terms
        and conditions of the Lease, including, but not limited to, the payment
        of rent, assumption of risk of loss, maintenance of insurance and
        maintenance of the Equipment, until such time as LESSOR receives the
        Purchase Price in full. The amount of rent to be paid by LESSEE shall be
        prorated to the date upon which the Purchase Price is received by LESSOR
        in full.


                                       OR


        2.   RENEW At its option, LESSEE may renew the Lease, for not less than
all of the Equipment, annually for a monthly rental payment based on the Fair
Market Value of the Equipment and the prevailing rates charged by the LESSOR.
All other terms and conditions of the Lease shall remain in effect.

     The Instructions included with this Letter must be followed in their
entirety. Questions and requests for assistance or for additional copies of the
Prospectus or this Letter may be directed to the Exchange Agent, at the address
listed above, or the Company, 234 Copeland Street, Quincy, MA 02169, 
Attention: Chief Financial Officer (telephone: (617) 786-4000).
 
Ladies and Gentlemen:
 
     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned tenders to the Company the number of Original Preferred Shares
indicated above. Subject to, and effective upon, the acceptance for exchange of
the Original Preferred Shares tendered with this Letter, the undersigned
exchanges, assigns and transfers to, or upon the order of, the Company all
right, title and interest in and to the Original Preferred Shares tendered.
 
     The undersigned constitutes and appoints the Exchange Agent as his or her
agent and attorney-in-fact (with full knowledge that the Exchange Agent also
acts as the agent of the Company) with respect to the tendered Original
Preferred Shares, with full power of substitution, to (a) deliver certificates
for such Original Preferred Shares; (b) deliver Original Preferred Shares and
all accompanying evidence of transfer and authenticity to or upon the order of
the Company upon receipt by the Exchange Agent, as the undersigned's agent, of
the New Preferred Shares to which the undersigned is entitled upon the
acceptance by the Company of the Original Preferred Shares tendered under the



                                        2
<PAGE>   3
Exchange Offer; and (c) receive all benefits and otherwise exercise all rights
of beneficial ownership of the Original Preferred Shares, all in accordance with
the terms of the Exchange Offer. The power of attorney granted in this paragraph
shall be deemed irrevocable and coupled with an interest.
 
     The undersigned hereby represents and warrants that he or she has full
power and authority to tender, exchange, assign and transfer the Original
Preferred Shares tendered hereby and that the Company will acquire good and
unencumbered title thereto, free and clear of all liens, restrictions, charges
and encumbrances and not subject to any adverse claim. The undersigned will,
upon request, execute and deliver any additional documents deemed by the Company
to be necessary or desirable to complete the assignment and transfer of the
Original Preferred Shares tendered.
 
     The undersigned agrees that acceptance of any tendered Original Preferred
Shares by the Company and the issuance of New Preferred Shares in exchange
therefor shall constitute performance in full by the Company of its obligations
under the Registration Agreement (as defined in the Prospectus) and that, upon
the issuance of the New Preferred Shares, the Company will have no further
obligations or liabilities thereunder (except in certain limited circumstances).
By tendering Original Preferred Shares, the undersigned certifies (a) that it is
not an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act, that it is not a broker-dealer that owns Original Preferred
Shares acquired directly from the Company or an affiliate of the Company, that
it is acquiring the New Preferred Shares in the ordinary course of the
undersigned's business and that the undersigned is not engaged in, and does not
intend to engage in, a distribution of New Preferred Shares or (b) that it is an
"affiliate" (as so defined) of the Company or of the initial purchasers in the
offering of the Original Preferred Shares, and that it will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable to it.
 
     The undersigned acknowledges that, if it is a broker-dealer that will
receive New Preferred Shares for its own account in exchange for Original
Preferred Shares that were acquired as a result of market-making activities or
other trading activities, it will deliver a prospectus in connection with any
resale of such New Preferred Shares. By so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
     The undersigned understands that the Company may accept the undersigned's
tender by delivering written notice of acceptance to the Exchange Agent, at
which time the undersigned's right to withdraw such tender will terminate.
 
     All authority conferred or agreed to be conferred by this Letter shall
survive the death or incapacity of the undersigned, and every obligation of the
undersigned under this Letter shall be binding upon the undersigned's heirs,
personal representatives, successors and assigns. Tenders may be withdrawn only
in accordance with the procedures set forth in the Instructions contained in
this Letter.
 
     Unless otherwise indicated under "Special Delivery Instructions" below, the
Exchange Agent will deliver New Preferred Shares (and, if applicable, a
certificate for any Original Preferred Shares not tendered but represented by a
certificate also encompassing Original Preferred Shares which are tendered) to
the undersigned at the address set forth in Box 1.
 
     The undersigned acknowledges that the Exchange Offer is subject to the more
detailed terms set forth in the Prospectus and, in case of any conflict between
the terms of the Prospectus and this Letter, the Prospectus shall prevail.

                                  INSTRUCTIONS
 
                         FORMING PART OF THE TERMS AND
                        CONDITIONS OF THE EXCHANGE OFFER
 
     1.  DELIVERY OF THIS LETTER AND CERTIFICATES.  Certificates for Original
Preferred Shares or a Book-Entry Confirmation, as the case may be, as well as a
properly completed and duly executed copy of this Letter and any other documents
required by this Letter, must be received by the Exchange Agent at its address
set forth herein on or before the Expiration Date. The method of delivery of
this Letter, certificates for Original Preferred Shares or a Book-Entry
Confirmation, as the case may be, and any other required documents is at the
election and risk of the tendering holder, but except as otherwise provided
below, the delivery will be deemed made when actually received by the Exchange
Agent. If delivery is by mail, the use of registered mail with return receipt
requested, properly insured, is suggested.
 
     Holders whose Original Preferred Shares are not immediately available or
who cannot deliver their Original Preferred Shares or a Book-Entry Confirmation,
as the case may be, and all other required documents to the Exchange Agent on or
before the Expiration Date may tender their Original Preferred Shares pursuant
to the guaranteed delivery procedures set forth in the Prospectus. Pursuant to
such procedure (i) tender must be made by or through an Eligible Institution (as
defined in the Prospectus under the caption "The Exchange Offer"); (ii) prior to
the Expiration Date, the Exchange Agent must have received from the Eligible
Institution a properly completed and duly executed Notice of Guaranteed Delivery
(by telegram, telex, facsimile transmission, mail or hand delivery) (x) setting
forth the name and address of the holder, the description of the Original
Preferred Shares and number of Original Preferred Shares tendered, (y) stating
that the tender is being made thereby and (z) guaranteeing that, within three
New York Stock Exchange trading days after the date of execution of such Notice
of Guaranteed Delivery, this Letter together with the certificates representing
the Original Preferred Shares or a Book-Entry Confirmation, as the case may be,
and any other documents required by this Letter will be deposited by the
Eligible Institution with the Exchange Agent; and (iii) the certificates for all
tendered Original Preferred Shares or a Book-Entry Confirmation, as the case may
be, as well as all other documents required by this Letter, must be received by
the Exchange Agent within three New York Stock Exchange trading days after the
date of execution of such Notice of Guaranteed Delivery, all as provided in the
Prospectus under the caption "The Exchange Offer -- How to Tender."
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Original Preferred Shares will
be determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders that are not in
proper form or the acceptance of which, in the opinion of the Company's counsel,
would be unlawful. The Company also reserves the right to waive any
irregularities or conditions of tender as to particular Original Preferred
Shares. All tendering holders, by execution of this Letter, waive any right to
receive notice of acceptance of their Original Preferred Shares.
 
     Neither the Company, the Exchange Agent nor any other person shall be
obligated to give notice of defects or irregularities in any tender, nor shall
any of them incur any liability for failure to give any such notice.
 
     2.  PARTIAL TENDERS; WITHDRAWALS.  If fewer than all of the Original
Preferred Shares evidenced by a submitted certificate or by a Book-Entry
Confirmation are tendered, the tendering holder must fill in the number tendered
in the fourth column of Box 1 above. All of the Original Preferred Shares
represented by a certificate or by a Book-Entry Confirmation delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.
A certificate for Original Preferred Shares not tendered will be sent to the
holder, unless otherwise provided in Box 5, as soon as practicable after the
Expiration Date, in the event that fewer than all of the Original Preferred
Shares represented by a submitted certificate are tendered (or, in the case of
Original Preferred Shares tendered by book-entry transfer, such non-exchanged
Original Preferred Shares will be credited to an account maintained by the
holder with the Book-Entry Transfer Facility).
 
     If not yet accepted, a tender pursuant to the Exchange Offer may be
withdrawn prior to the Expiration Date. To be effective with respect to the
tender of Original Preferred Shares, a notice of withdrawal must (i) be received
by the Exchange Agent before the Company notifies the Exchange Agent that it has
accepted the tender of Original Preferred Shares pursuant to the Exchange Offer;
(ii) specify the name of the person who tendered the Original Preferred Shares;
(iii) contain a description of the Original Preferred Shares to be withdrawn,
the certificate numbers shown on the particular certificates evidencing such
Original Preferred Shares and the number of Original Preferred Shares
represented
                                        8
<PAGE>   9
 
by such certificates; and (iv) be signed by the holder in the same manner as the
original signature on this Letter (including any required signature guarantee).
 
     3.  SIGNATURES ON THIS LETTER; ASSIGNMENTS; GUARANTEE OF SIGNATURES.  If
this Letter is signed by the holder(s) of Original Preferred Shares tendered
hereby, the signature must correspond with the name(s) as written on the face of
the certificate(s) for such Original Preferred Shares, without alteration,
enlargement or any change whatsoever.
 
     If any of the Original Preferred Shares tendered hereby are owned by two or
more joint owners, all owners must sign this Letter. If any tendered Original
Preferred Shares are held in different names on several certificates, it will be
necessary to complete, sign and submit as many separate copies of this Letter as
there are names in which certificates are held.
 
     If this Letter is signed by the holder of record and (i) all of the
holder's Original Preferred Shares are tendered; and/or (ii) untendered Original
Preferred Shares, if any, are to be issued to the holder of record, then the
holder of record need not endorse any certificates for tendered Original
Preferred Shares, nor provide a separate bond power. If any other case, the
holder of record must transmit a separate bond power with this Letter.
 
     If this Letter or any certificate or assignment is signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing and proper evidence satisfactory to the
Company of their authority to so act must be submitted, unless waived by the
Company.
 
     Signatures on this Letter must be guaranteed by an Eligible Institution,
unless Original Preferred Shares are tendered (i) by a holder who has not
completed the Box entitled "Special Issuance Instructions" or "Special Delivery
Instructions" on this Letter; or (ii) for the account of an Eligible
Institution. In the event that the signatures in this Letter or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantees
must be by an eligible guarantor institution which is a member of The Securities
Transfer Agents Medallion Program (STAMP), The New York Stock Exchanges
Medallion Signature Program (MSP) or The Stock Exchanges Medallion Program
(SEMP) (collectively, "Eligible Institutions"). If Original Preferred Shares are
registered in the name of a person other than the signer of this Letter, the
Original Preferred Shares surrendered for exchange must be endorsed by, or be
accompanied by a written instrument or instruments of transfer or exchange, in
satisfactory form as determined by the Company, in its sole discretion, duly
executed by the registered holder with the signature thereon guaranteed by an
Eligible Institution.
 
     4.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering holders should
indicate, in Box 4 or 5, as applicable, the name and address to which the New
Preferred Shares or certificates for Original Preferred Shares not exchanged are
to be issued or sent, if different from the name and address of the person
signing this Letter. In the case of issuance in a different name, the tax
identification number of the person named must also be indicated. Holders
tendering Original Preferred Shares by book-entry transfer may request that
Original Preferred Shares not exchanged be credited to such account maintained
at the Book-Entry Transfer Facility as such holder may designate.
 
     5.  TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a
holder whose tendered Original Preferred Shares are accepted for exchange must
provide the Exchange Agent (as payor) with his or her correct and properly
certified taxpayer identification number ("TIN"), which, in the case of a holder
who is an individual, is his or her social security number. If the Exchange
Agent is not provided with the correct TIN, the holder may be subject to a $50
penalty imposed by the Internal Revenue Service. In addition, delivery to the
holder of the New Preferred Shares pursuant to the Exchange Offer may be subject
to back-up withholding. (If withholding results in overpayment of taxes, a
refund or credit may be obtained.) Exempt holders (including, among others,
substantially all corporations and nonresident aliens) are not subject to these
back-up withholding and reporting requirements. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
     Under federal income tax laws, payments that may be made by the Company on
account of New Preferred Shares issued pursuant to the Exchange Offer may be
subject to back-up withholding at a rate of 31%. In order to avoid being subject
to back-up withholding, each tendering holder must provide his or her correct
TIN by completing the "Substitute Form W-9" referred to above, certifying that
the TIN provided is the holder's correct TIN(or that the holder is awaiting a
TIN) and that (i) the holder has not been notified by the Internal Revenue
Service that he or she is subject to back-up withholding as a result of failure
to report all interest or dividends; or (ii) the Internal Revenue Service has
notified the holder that he or she is no longer subject to back-up withholding;
or (iii) such holder is exempt from back-up

                                        9

withholding. If the Original Preferred Shares are in more than one name or are
not in the name of the actual owner, consult the enclosed Guidelines for
information on which TIN to report.
 
     6.  TRANSFER TAXES.  The Company will pay all transfer taxes, if any,
applicable to the transfer of Original Preferred Shares to it or its order
pursuant to the Exchange Offer. If, however, the New Preferred Shares or
certificates for Original Preferred Shares not exchanged are to be delivered to,
or are to be issued in the name of, any person other than the record holder, or
if tendered certificates are recorded in the name of any person other than the
person signing this Letter, or if a transfer tax is imposed by any reason other
than the transfer of Original Preferred Shares to the Company or its order
pursuant to the Exchange Offer, then the amount of such transfer taxes (whether
imposed on the record holder or any other person) will be payable by the
tendering holder. If satisfactory evidence of payment of taxes or exemption from
taxes is not submitted with this Letter, the amount of transfer taxes will be
billed directly to the tendering holder.
 
     Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the certificates listed in this Letter.
 
     7.  WAIVER OF CONDITIONS.  The Company reserves the absolute right to amend
or waive any of the specified conditions in the Exchange Offer in the case of
any Original Preferred Shares tendered.
 
     8.  MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATES.  Any holder whose
certificates for Original Preferred Shares have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated above for
further instructions.
 
     9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions relating to
the procedure for tendering, as well as requests for additional copies of the
Prospectus or this Letter, may be directed to the Exchange Agent.
 
     IMPORTANT:  This Letter (together with certificates representing tendered
Original Preferred Shares or a Book-Entry Confirmation and all other required
documents) must be received by the Exchange Agent on or before the Expiration
Date (as defined in the Prospectus).

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9
 
GUIDELINES FOR DETERMINING THE PROPER IDENTIFICATION NUMBER TO GIVE THE
PAYER.--Social Security numbers have nine digits separated by two hyphens: i.e.
000-00-000. Employer identification numbers have nine digits separated by only
one hyphen: i.e. 00-0000000. If you are a resident alien and you do not have and
are not eligible to get a social security number, you should obtain from the IRS
an "individual taxpayer identification number" (ITIN) and provide that ITIN. The
table below will help determine the number to give the payer.

    - Section 404(k) payments made by an ESOP.
 
    Payments of interest not generally subject to backup withholding include the
following:
    - Payments of interest on obligations issued by individuals. Note: You may
      be subject to backup withholding if this interest is $600 or more and is
      paid in the course of the payer's trade or business and you have not

    - Payments on tax-free covenant bonds under section 1451.

Exempt payees described above should complete the Substitute Form W-9 to avoid
possible erroneous backup withholding. IF YOU ARE AN EXEMPT PAYEE, FURNISH YOUR

interest, or other payments to give correct taxpayer identification numbers to
payers who must report the payments to IRS. IRS uses the numbers for
identification purposes and to help verify the accuracy of tax returns. Payers
must be given the numbers whether or not recipients are required to file tax
returns. Payers must generally withhold 31% of taxable interest, dividend, and
certain other payments to a payee who does not furnish a taxpayer identification
number to a payer. Certain penalties may also apply.
 
PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless you failure is due to reasonable
cause and not to willful neglect.
(2) CIVIL PENALTY FOR FAILURE INFORMATION WITH RESPECT TO WITHHOLDING--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.
