                               PROSPECTUS SUMMARY

   We have prepared this summary to assist you in your review of this
prospectus. This summary highlights what we believe are the significant aspects
of our business and this offering. However, we have not included all of the
information that may be important to you. You should carefully read this entire
prospectus, including the specific risks described in the "Risk Factors"
section beginning on page 10 and the other documents to which we refer in this
prospectus. For more information about us, see "Where You Can Find More
Information." Unless otherwise specifically stated, all information in this
prospectus gives effect to the conversion of all of our outstanding preferred
stock to common stock, which will occur at the closing of this offering, but
does not take into account the possible issuance of additional shares of common
stock to the underwriters pursuant to their right to purchase additional shares
to cover over-allotments.

Overview

   We are a nationwide integrated communications provider using state-of-the-
art technology and a solutions-oriented sales approach focused on medium-sized
business customers. We believe that our competitive advantages are our
experienced, data-oriented nationwide sales force of approximately 250 sales
professionals, our integrated operational support systems and our nationwide
integrated data and voice network. We currently offer an integrated or bundled
package of broadband Internet, local and long distance services and a suite of
value-added data and voice communications applications, including Web hosting,
virtual private networks using Internet Protocol and frame relay. We deliver
these services and applications primarily over a broadband T-1 connection, or
in some cases over a digital subscriber line, or DSL, connection. Our revenue
increased through internal growth to $31.4 million in 1999 from $13.2 million
in 1998.

   We currently sell our services primarily in Tier I and Tier II markets to
medium-sized businesses with 25 to 500 employees and annual revenue of $5
million to $225 million, a market segment we perceive as under-served. Our
target customers typically have limited information technology resources and do
not have a full-time communications professional. These customers respond
positively to our solutions-oriented sales approach and the value proposition
of our integrated bundle of data and voice services invoiced on a single bill.
To reach these customers most effectively, we market our services through three
sales channels: our direct sales force, Branchises (a cooperative sales
relationship in which we partner with independent, experienced
telecommunications sales professionals who build sales teams to exclusively
sell our services) and independent sales agents. As of March 31, 2000, we had
200 direct sales professionals in 15 sales offices, 11 Branchises with
approximately 50 sales representatives and an additional 25 independent agents;
together, these sales channels serve a total of 21 markets.

   Our integrated operational support systems automate all stages of the
customer relationship from initial sale through billing. These systems also
enable us to offer our customers a single point of contact for all aspects of
customer care and billing, which we believe results in higher customer
satisfaction and retention. Our customer care department

                                       3
<PAGE>

provides multiple levels of customer service, tailored to the size of the
customers and their needs. Our customers receive a single bill for all of our
services that can be delivered either by mail or directly over our secure Web
site, enabling them to manage their communications services efficiently, create
and review numerous usage reports and pay us electronically. Our approximately
50 full-time systems professionals are continually refining the integration of
these systems, adding new enhancements and incorporating new technology to
improve our customers' experience and the efficiency of our operations.

   Our packet-switched network enables us to offer integrated broadband data
and voice services over a single connection to our customers. We intend to
deploy our network in several phases, the first of which, or Phase I, will
include 21 switches serving 26 markets. As of March 31, 2000, we had purchased
and installed 10 switches in Atlanta, Boston, Chicago, Dallas, Los Angeles,
Miami, New York, Phoenix, San Diego and Washington, DC. We intend to install
the remaining 11 switches to complete our Phase I network deployment by the end
of 2000. We purchased our switching solution on a turnkey basis from one of our
strategic partners and investors, Nortel Networks Inc. To connect all of our
switches, we purchased approximately 9,000 miles of OC-3 fiber from Williams
Communications, Inc., another strategic partner and investor. Our partnership
with Williams allows us to use its network infrastructure to provide service to
14 additional markets where our traffic does not yet justify locating a switch
or making the associated capital investments. Upon the completion of our Phase
I deployment, we intend to begin the second phase, or Phase II, of our
deployment, installing 12 additional switches.

Business Strategy

   Our mission is to provide medium-sized business customers with an integrated
package of broadband services and applications delivered over our state-of-the-
art data and voice network, using a solutions-oriented, face-to-face sales
approach. The key elements of our strategy to accomplish this mission are:

  .   Focus on Medium-sized Business Customers. We focus our efforts on
      under-served medium-sized business customers and offer them integrated
      data and voice communications services designed to suit all of their
      business needs.

  .   Offer Integrated Communications Services Using a Single Broadband
      Connection. Using an integrated T-1 connection, we offer broadband
      Internet, local and long distance services and a suite of value-added
      services, including Web hosting, virtual private networks using
      Internet Protocol and frame relay.

  .   Capitalize on Multiple Sales Channels. We market to our target
      customers through established nationwide sales channels, including
      direct sales, Branchises and independent agents, to maximize our
      selling efforts.

  .   Implement Integrated Operational Support Systems. We are continuing to
      implement integrated operational support systems that synchronize
      multiple tasks, shorten our provisioning cycle, expedite service to our
      customers and enhance our customer care.

                                       4
<PAGE>


  .  Provide Superior Customer Care. We strive to provide one call
     resolution, using a single point of contact to resolve any customer
     issue, ensure customer satisfaction and maximize retention rates.

  .  Deploy an Integrated and Flexible Nationwide Network. We employ a "smart
     build" strategy, installing integrated data and voice switches,
     purchasing long haul fiber and leasing local fiber where we have, or
     plan to have, a sales presence.

  .  Develop Advanced Service Offerings and Applications Through Strategic
     Relationships. We partner with companies that provide leading data and
     voice applications in order to provide our customers with comprehensive
     communications solutions.

  .  Benefit from Experienced Management and Sponsorship. Our senior
     executives and sponsors have significant experience in building
     successful Internet, local and long distance companies.

Recent Developments

   On April 13, 2000, we entered into a $35 million loan agreement with Gold &
Appel Transfer, S.A. We may borrow funds under the loan agreement at any time
from July 5, 2000 until the earlier to occur of July 5, 2001 or the closing of
this offering. Amounts outstanding under the loan agreement bear interest at a
rate of 12% per annum. Amounts outstanding under the loan agreement may be
converted at the election of holders of at least 75% of our Series B Redeemable
Convertible Preferred Stock, or the Series B Preferred Stock, into common stock
at a price per share which is equal to the conversion price per share of any
convertible preferred stock (or the price per share of any common stock) we
issue between April 13, 2000 and the closing of this offering. Amounts
outstanding under the loan agreement may be repaid at any time, and must be
repaid upon the earlier of July 5, 2001 or the closing of this offering.

   On April 20, 2000, in a private placement, we issued $12 million of our
Series C Redeemable Convertible Preferred Stock, or the Series C Preferred
Stock. The shares of Series C Preferred Stock will automatically convert into
shares of our common stock upon the closing of this offering at a price per
share which is equal to the lesser of 75% of the price per share in this
offering or $14.13.

     Summary Historical and Pro Forma Consolidated Financial and Other Data

   The following table presents our summary historical and pro forma
consolidated financial and other data. This table should be read together with
our consolidated financial statements and related notes and "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
presented elsewhere in this prospectus.

   EBITDA consists of net income (loss) excluding net interest, taxes,
depreciation and amortization. EBITDA is provided because it is a measure of
financial performance commonly used in the communications industry, and it is
used by our management to measure our performance. We have presented EBITDA to
enhance your understanding of our operating results. You should not construe it
as an alternative to operating income, as an indicator of our operating
performance, as an alternative to cash flows from operating activities or as a
measure of liquidity determined in accordance with generally accepted
accounting principles. We may calculate EBITDA differently than other
companies. For further information, see our consolidated financial statements
and related notes presented elsewhere in this prospectus.

   The pro forma balance sheet data as of December 31, 1999 gives effect to the
issuance of our Series C Preferred Stock as if our Series C Preferred Stock was
issued on that date. The pro forma as adjusted balance sheet data as of
December 31, 1999 gives effect to the above and to the issuance and sale of
                 shares of common stock in this offering and the automatic
conversion of our preferred stock into common stock as if the issuance, sale
and conversion occurred on December 31, 1999. The operating results for the
year ended December 31, 1999 are not necessarily indicative of the results to
be expected for any future period. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

                                  RISK FACTORS

   You should carefully consider the following factors and other information in
this prospectus before you decide whether to purchase our common stock. The
risks set forth below are in addition to risks that apply to most businesses.

   If any of the following risks actually occurs, our business, prospects,
financial condition and results of operations could be materially adversely
affected, which could result in the decrease of the market price of our common
stock and the potential loss of part or all of your investment.

                         Risks Related to Our Business

Our performance may be difficult to evaluate because we have had a limited
operating history and have recently changed the focus of our business.

   We were founded as a long distance company in June 1996. In 1997, our
residential casual calling program was the source of nearly 100% of our
revenue. However, in 1998, we changed our customer focus from residential to
medium-sized businesses and also expanded our service offerings to include data
and voice communications. As a result, our residential casual calling program
has decreased as a percentage of our revenue from approximately 42% in 1998 to
approximately 9% in 1999. As we continue to focus on servicing medium-sized
business customers, we expect that substantially all of our revenue will be
generated from these customers during 2000 and thereafter. Because of our
limited history and our changed business focus, you have limited relevant
operating and financial data about us to evaluate our performance and to use as
a basis for making your investment decision.

   Our business plan includes the introduction of additional data and voice
communications services, which we have limited experience offering. In
addition, we began offering local service in five markets in March 2000. There
are risks related to these new service offerings and to our entry into the
market for these services, including our inability to recoup costs associated
with new product development, sales and marketing, intense competition in such
markets from other companies already offering these services and potential
competition from companies that have greater financial resources and experience
than we do. If we are unable to achieve adequate market acceptance in the
markets we target for these additional services, we may fall short of our
financial goals, and our ability to increase our revenue will be greatly
diminished.

Since inception, we have had losses from operations and negative operating cash
flow and expect to continue to do so.

   We incurred losses from operations of $529,000 in 1996, $2.0 million in
1997, $20.8 million in 1998 and $47.4 million in 1999. We also used net cash in
operations of $499,000, $1.9 million, $17.6 million and $36.8 million,
respectively, in each of these years. The development of our business, the
deployment of our services and systems and the expansion of our network will
require significant capital expenditures, a substantial

                                       10
<PAGE>

portion of which will need to be incurred before we generate revenue and cash
flow from these investments. After the completion of this offering, we believe
that we will incur further losses and will continue to have negative cash flow
from operating activities as we fund operating losses and capital expenditures
for our Phase I deployment.

   In addition, it is currently unknown if net operating loss carryforwards,
generated for tax purposes, will expire unused. The Tax Reform Act of 1986, as
amended, limits the use of net operating loss carryforwards in certain
situations where changes occur in the stock ownership of a company. If we
should have an ownership change, as defined for tax purposes, utilization of
the carryforwards could be restricted.

Our continued growth and expansion may require additional capital, which we may
be unable to obtain.

   As we continue to develop our business, increase our service offerings and
expand our network, we will require significant additional capital. We believe
that the net proceeds from this offering, along with amounts available under a
credit agreement we have with Nortel and other vendor financing and cash
generated from our operations, will be sufficient to meet our planned capital
requirements for Phase I of our network deployment and to fund our anticipated
operating losses for this phase. However, if we choose to enter additional
markets, enter markets earlier than currently anticipated, make acquisitions or
if we exceed market penetration estimates, then we may require additional
capital to continue our growth and operating plans. If we fall significantly
short of our estimates for operating and financial performance, we may also
require more capital. Furthermore, we may need additional financing for future
capital expenditures to implement our business plan, including constructing our
network and our operational support systems; offering new broadband
communications services; and paying scheduled principal and interest payments
on our debt.

   Although our credit agreement with Nortel permits us to borrow up to an
additional $80.9 million as of March 31, 2000, such credit agreement includes
various financial, operating and other affirmative and negative covenants,
which limit our ability to incur additional debt from other lenders. In
addition, if we fail to comply with the covenants, we will not be able to
borrow additional amounts from Nortel, and we may be required to repay
principal prior to its intended maturity date. We may be unable to raise needed
capital on terms acceptable to us or at all. If we raise funds through the
issuance of our common stock, the issuance of such additional shares could
currently affect the market price of our common stock. If we are unable to
raise additional capital as we need it, we may have to change our growth and
operating plans or otherwise forgo market opportunities.

Our future success depends on the reliability of our network infrastructure,
and any failure could cause interruptions in the service we provide to our
customers.

   Our success will depend on the capacity, reliability and security of our
data and voice network and the networks of other carriers who carry a
significant portion of our traffic, such as Williams Communications, Inc.,
Epoch Networks, Inc. and Global Crossing. We

                                       11
<PAGE>

expect that substantially all of our future revenue will be derived from
providing data and voice communications services. We must provide superior
reliability, capacity and service on a cost-effective basis to implement our
business plans successfully. Our operations depend on our ability to protect
our network against damage from acts of nature, power failures, equipment
failures and similar events. Because we lease a portion of our fiber
transmission capacity from other carriers, we depend on these companies for
physical repair and maintenance of our leased lines. In addition, under the
terms of our agreement with Williams, Williams is responsible for physical
repair and maintenance of the fiber optic capacity we purchased from them.
Despite the precautions we and these other carriers take, a natural disaster,
fire, electrical outage or other unanticipated problem could occur at any of
our facilities or their facilities. If an unanticipated problem occurs, it may
cause interruptions in the services we provide and could limit our ability to
meet our customers' requirements, which could significantly reduce the demand
for our services or cause us to lose customers.

We must continue to expand our network to meet our goals.

   We must continue to expand our network in a timely and cost-effective manner
in order to meet our business plan and projected results of operations. We may
be unable to meet our scheduled expansion because of a number of factors,
including:

  .  cost overruns;

  .  unavailability of appropriate facilities, communications capacity,
     equipment, technical employees or additional capital;

  .  strikes;

  .  delays in obtaining governmental or other third-party consents;

  .  natural disasters; and

  .  other unforeseeable events.

As a result, we cannot be sure that we will be able to expand or adapt our
network infrastructure to meet our customers' demands, which could cause us to
lose customers.

We must properly manage our growth to meet our goals.

   We must continue to successfully implement our business plan, to properly
manage our rapid growth and to develop and expand our operational support
systems, such as customer care, billing, finance and accounting. Rapid growth
may also place a significant strain on our management, operational, financial
and other resources and on our systems and controls. Expansion also requires
the training and retention of current and additional employees to manage the
increased volume and added complexity of our business.

We depend on key personnel. If we are unable to hire and retain sufficiently
qualified personnel, our business may suffer.

   Our performance depends on the continuing contributions of key management,
sales, technical and finance personnel. Our business is managed by our founder,
James Kenefick, who is our Chairman of the Board, Chief Executive Officer and
President. In addition to

                                       12
<PAGE>

Mr. Kenefick, we rely on each of our senior sales and financial officers, who
make significant contributions to the success of our business. We believe that
our future success depends on the hiring and retention of skilled and qualified
management, sales, technical and finance personnel. Competition for these
qualified employees is intense, especially in the Washington, DC metropolitan
region, and may become even more intense in the future. We cannot give you any
assurance that we will be able to retain current key personnel or to hire and
retain needed additional personnel.

Our network infrastructure and our services depend upon the networks and
services of outside providers, making us vulnerable to service interruptions
and increased costs.

   We rely on other companies to supply a portion of our network
infrastructure, including transmission capacity, network equipment and resold
data and voice services. Because we rely on others, we are vulnerable to the
possibility that our suppliers may:

  .  compete with us;

  .  not provide service or equipment to us in a timely manner;

  .  enter into exclusive arrangements with our competitors; or

  .  stop selling their services or components to us at commercially
     reasonable prices, or at all.

   In addition, as a recent entrant into the competitive local
telecommunications services industry, we face numerous operating complexities,
and in many instances must rely on certain services and facilities of incumbent
local exchange carriers, or ILECs. Many competitive local exchange carriers,
known as CLECs, have experienced difficulties in negotiating and working with
the ILECs with respect to ordering, interconnecting, leasing premises and
implementing the systems used by CLECs for interconnection, access to unbundled
network elements and resale of ILEC services. Various rules requiring ILECs to
provide services and facilities to CLECs are subject to appeal. The outcome of
these appeals may have an adverse effect upon us.

   Coordination with ILECs is necessary for new carriers like us to provide
local service to customers on a timely and competitive basis. The
Telecommunications Act of 1996, or the "Telecommunications Act," creates an
incentive for Regional Bell Operating Companies, known as RBOCs, to cooperate
with new carriers and permit access to their networks by denying RBOCs the
ability to provide long distance services within the same region in which they
provide local service until they have satisfied statutory conditions designed
to open their local markets to competition. However, we cannot assure you that
RBOC cooperation will not suffer further once RBOCs are permitted to offer in-
region long distance service. If we are unable to obtain the cooperation of an
RBOC in a region, our ability to offer local services in such region on a
timely and cost-effective basis would be adversely affected.

Our business is vulnerable to operational support systems failures.

   Sophisticated operational support systems are vital to our ability to
process customer orders, generate accurate and timely bills for our services,
monitor costs and achieve

                                       13
<PAGE>

operating efficiencies. We are currently implementing these systems, and we
have not yet completed certain components of these systems. If we do not
properly implement these systems, if our systems fail to perform in a timely
and effective manner and at acceptable costs or if we fail to adequately
identify and plan for all of our information and processing needs, these
failures could have a material adverse effect on our business.

If our estimates of our traffic levels are not correct, we may have too much or
too little capacity, either of which would increase our costs.

   We currently rely on other carriers to provide us with switching,
transmission and termination services for our off-net data and voice traffic
and for our on-net transmission capacity where we do not own fiber optic
capacity. We must estimate future supply and demand for transmission capacity
and our future calling patterns and traffic levels and negotiate favorable
terms and conditions with these carriers. If we underestimate our requirements,
we may be required to buy these services at unfavorable rates. If we
overestimate our needs, we may have idle capacity, which would increase our
per-unit costs.

We depend on portions of the ILECs' networks for DSL technology, and this DSL
technology may not operate as expected on the ILECs' networks.

   To provide DSL services, we depend significantly on the quality of the
copper telephone lines we obtain from ILECs providing services in our target
markets and their maintenance of these lines. We cannot assure you that we will
be able to obtain the copper telephone lines and the services we require from
these ILECs on a timely basis or at quality levels, prices, terms and
conditions satisfactory to us or that such ILECs will maintain the lines in a
satisfactory manner.

We depend on leased trunking capacity, and failure to obtain permits or rights-
of-way may affect our ability to develop our network.

   Under our network build-out strategy, we initially will seek to lease from
ILECs and CLECs local fiber trunking capacity connecting our switches to
particular ILEC central offices. In the future, we may seek to replace this
leased trunk capacity with our own fiber if warranted by traffic volume growth.
We cannot assure you that all required trunking capacity will be available to
us on a timely basis or on favorable terms. The failure to obtain such leased
fiber could delay our ability to penetrate some of our markets or require us to
make additional unexpected up-front capital expenditures to install our own
fiber and could have a material adverse effect on our business, financial
condition and results of operations.

   If we seek to install our own fiber, or, in some cases, even if we lease
fiber, we must obtain local franchises and other permits, as well as rights-of-
way to utilize underground conduit and aerial pole space and other rights-of-
way from entities, such as ILECs and other utilities, railroads, long distance
companies, state highway authorities, local governments and transit
authorities. We cannot assure you that we will be able to obtain and maintain
the franchises, permits and rights needed to implement our network build-out

                                       14
<PAGE>

on favorable terms. The failure to enter into and maintain any such
requirements for a particular network may affect our ability to develop that
network and may have a material adverse effect on our business, financial
condition and results of operations.

Security breaches could interrupt, delay or otherwise interfere with the
services we provide to our customers.

   Despite our network security measures, our network may be vulnerable to
computer viruses, break-ins and similar disruptive problems. We may experience
future interruptions in service as a result of the accidental or intentional
actions of Internet users, current or former employees or others. Unauthorized
use might also jeopardize the security of the confidential information stored
in our computer systems and the computer systems of our customers. Although we
intend to continue to implement security measures to prevent these problems,
security measures employed by others have been circumvented in the past, and
the possibility exists that our security measures will be circumvented in the
future. In addition, eliminating computer viruses and remedying security
problems may cause interruptions, delays or cessation of service to our
customers. If our security measures fail, we may lose customers, and our
reputation may be damaged.

We may make acquisitions or enter into joint ventures or strategic alliances,
each of which is accompanied by inherent risks.

   Some of our growth may come from acquisitions of other businesses, joint
ventures or strategic alliances with other companies. Any of these growth
strategies would create additional risks for us. Some of the common risks that
would be possible include:

  .  the difficulty of incorporating acquired operations and personnel with
     ours;

  .  the potential disruption of our ongoing business, including the
     diversion of resources and management time;

  .  the difficulty of maintaining uniform standards, controls, procedures
     and policies;

  .  the risks of entering markets where we have little or no direct prior
     experience; and

  .  the impairment of relationships with employees or customers because of
     changes in management.

We may be liable for information sent through our network.

   The law relating to the liability of private network operators, Internet
service providers and on-line service providers for information carried on or
disseminated through their networks is currently unsettled. We may be sued for
the content disseminated through our network. For example, lawsuits may be
brought against us claiming that material on our network on which one of our
customers relied was inaccurate or infringes on the intellectual property
rights of others. If we are sued, we may have to spend significant amounts of
money and management resources defending ourselves against the claims, and if
we are not successful in our defense, the amount of damages that we will have
to pay may be significant. In addition, we may decide to take costly steps to
reduce our exposure to these risks.

                         Risks Related to Our Industry

Government regulation of telecommunications companies is constantly changing.

   We are subject to regulation at the federal, state and local levels, and
this regulatory environment frequently changes. The Federal Communications
Commission issued regulations revising the obligations of companies like ours,
which buy access to local exchange networks, to pay charges for the local
exchange access. As a provider of interstate and international services, we
also are required to contribute to federal universal service as well as to
state universal service in those states in which we provide intrastate toll and
local services. Additionally, the FCC has issued regulations limiting the use
of customer proprietary network information and requiring pay phone operators
to be paid for each completed call started from a pay phone. These rules, while
effective, also are subject to ongoing administrative proceedings, and we are
unable to predict possible changes to the existing rules or how they will
affect our business.

   To provide local exchange service, companies like ours currently are
required by law to:

  .  interconnect with other carriers;

  .  allow access to rights-of-way;

  .  permit resale of our retail services;

  .  offer reciprocal compensation for termination of traffic; and

  .  provide dialing parity and number portability.

   In addition, the law currently requires ILECs, including the RBOCs, to:

  .  provide unbundled access to their local exchange network elements;

  .  provide their retail services at wholesale prices to promote resale; and

  .  permit other carriers like us to collocate our equipment at their
     facilities.

Many of these rules have been appealed, and we cannot predict how the appeals
will be resolved or what impact they will have on our business.

The markets for data and voice communications services are highly competitive,
and the local markets have been opened for competition. We may not be able to
compete effectively in any of these markets.

   The data and voice communications industries have numerous participants,
including a large number of carriers in the cities where we compete, and most
of those carriers have greater resources, more established networks and broader
customer bases than we do. In addition, continued deregulation of the
telecommunications industry likely means that we will be faced with increased
competition in the future. Moreover, established telecommunications companies
are beginning to, or may, offer new services beyond their traditional services.
For example, local telephone companies are offering long distance service.
Mergers and alliances in the telecommunications industry also may create
significant new competitors with resources far greater than ours.

                                       16

Regulation of reciprocal compensation is changing.

   The Telecommunications Act requires a carrier offering local service to
compensate another carrier when it delivers a local call to a customer on the
other telephone company's network; this payment is typically referred to as
"reciprocal compensation." A number of ILECs have contested the obligation to
pay this reciprocal compensation to CLECs for local telephone calls from a
customer on the ILEC network to an ISP on the CLEC network. The FCC has
determined that Internet-bound traffic is largely interstate in nature.
Consequently, some states have reevaluated prior rulings regarding the
applicability of reciprocal compensation to Internet traffic. However, on March
24, 2000, the Circuit Court for the District of Columbia vacated the FCC's
ruling on this issue, holding that the FCC did not adequately explain the
rationale underlying its decision, and remanded it to the FCC for further
proceedings. Despite the DC Circuit's ruling, however, there is no assurance
that any future court, state regulatory commission or FCC decision on this
matter will be favorable. An adverse decision in such proceedings could have a
materially adverse effect on our future revenue.

There are rapid technological changes in the data and voice communications
industries. Our inability to adapt to these technological changes could affect
our business.

   The data and voice communications industries are subject to rapid and
significant changes in technology and in customer requirements and preferences.
We must rely, to a significant extent, on third parties for the development of
and access to new technologies and for many of our advanced service offerings
and applications. New technologies could reduce the competitiveness of our
network or of our current service offerings. We may be required to select one
technology over another, but at a time when it would be impossible to predict
with any certainty which technology will prove to be the most economic,
efficient or capable of attracting customer usage. Subsequent technological
developments may reduce the competitiveness of our network or service offerings
and require unbudgeted upgrades or additional services that could be expensive
and time consuming. If we fail to obtain access to important technologies, our
business could be materially and adversely affected.

   The effect of technological changes on our business cannot be predicted. We
believe that our future success will depend, in part, on our ability to
anticipate or adapt to such changes and to offer, on a timely basis, services
that meet customer demands. We cannot assure you that we will obtain access to
new technology on a timely basis or on satisfactory terms. Any failure by us to
obtain new technology could have a material adverse effect on our business,
financial condition or results of operations.

FCC and state regulations may limit the services we can offer.

   Our networks and the provisioning of telecommunications services are subject
to significant regulation at the federal, state and local levels. Delays in
receiving required regulatory approvals or the enactment of new regulations may
have a material adverse effect upon our business, financial condition and
results of our operations. We cannot assure you that the FCC or state
commissions will grant required authority or

                                       17
<PAGE>

refrain from taking action against us if we are found to have provided services
without obtaining the necessary authorizations. If authority is not obtained
and maintained, or if our schedules of prices, terms and conditions, also
referred to as tariffs, are not filed, or are not updated or otherwise do not
fully comply with the rules of the FCC or state regulatory agencies, third
parties or regulators could challenge our authority to provide service or the
validity of these filings. Such challenges could cause us to incur substantial
legal and administrative expenses.

   Our Internet operations are not currently subject to direct regulation by
the FCC or any other governmental agency, other than regulations applicable to
businesses in general. However, the FCC recently has indicated that it may re-
examine this status. We are unable to predict what regulations may be adopted
in the future, or the extent to which existing laws and regulations may be
found applicable, or the impact such new or existing laws may have on our
business. New laws or regulations relating to Internet services, or existing
laws found to apply to them, may have a material adverse effect on our
business, financial condition or results of operations.

   The Telecommunications Act remains subject to judicial review and additional
FCC rulemaking, and it is therefore difficult to predict what effect the
legislation will have on us and our operations. There are currently many
regulatory actions underway or that may be initiated regarding interconnection
and network element pricing and other issues that could result in significant
changes to business conditions in the telecommunications industry. We cannot
assure you that these changes will not have a material adverse effect on our
business, financial condition or results of operations.

                         Risks Related to This Offering

We are controlled by a small number of investors whose interests may not be
aligned with yours.

   After the closing of this offering, Gold & Appel and James Kenefick will
beneficially own     % and    %, respectively, of our common stock. As a
result, Gold & Appel and Mr. Kenefick will be able to determine the outcome of
any matter requiring a stockholder vote, including the election of directors
who are responsible for the management of our affairs. Matters that typically
require stockholder approval include, in addition to the election of directors:

  .  amendment of our certificate of incorporation;

  .  acquisitions of other companies or assets;

  .  mergers or consolidations of our company with another company;

  .  sale of all or substantially all of our assets; and

  .  our dissolution and liquidation.

Some decisions concerning our operations or financial structure may present
conflicts of interest between Gold & Appel and our other stockholders. For
example, Gold & Appel also invests in other ISPs and telecommunications
companies, which may create conflicts

                                       18
<PAGE>

of interest because these companies compete, or may compete, with us. In
addition, conflicts may occur in the negotiation or enforcement of arrangements
we enter into with companies in which Gold & Appel or Mr. Kenefick have an
interest, including, for example, our agreement with Epoch. The concentration
of ownership of our common stock may also delay, deter or prevent a change of
control, which could reduce the market price.

You will experience immediate and substantial dilution in the book value of our
common stock.

   The price you pay for our common stock will be substantially higher than the
book value of our common stock. As a result, you will experience immediate and
substantial dilution in the combined net tangible book value of your shares of
$    per share, while current stockholders will receive a material increase in
the combined net tangible book value of their shares of our common stock. In
addition, your common stock will be diluted because upon the completion of this
offering,      shares will be issuable upon the exercise of outstanding options
and warrants.

   Under our 1998 Stock Incentive Plan, we issued options to certain of our
employees at prices which reflected the market price at the time, but which are
now significantly lower than the initial public offering price. As of December
31, 1999, options for approximately 348,000 shares are exercisable at $0.17 per
share, 51,333 shares are exercisable at $0.187 per share, 85,500 shares are
exercisable at $1.98 per share, 109,329 shares are exercisable at $5.52 per
share and 43,073 shares are exercisable at $6.83 per share.

   We may also grant options for up to 15% of the outstanding shares of our
common stock under our 1998 Stock Incentive Plan and the proposed NETtel Long-
Term Incentive Plan and warrants for up to 1% of the outstanding shares of our
common stock to Branchises.

Our management has broad discretion as to how to use the proceeds from this
offering, and those proceeds may not be used appropriately.

   We intend to use the net proceeds from this offering for general purposes,
including working capital, capital expenditures, geographic expansion of our
operations and possible future acquisitions of or investments in businesses,
assets or technologies. Our management will have broad discretion over how we
use these proceeds. You will not have the opportunity to evaluate the economic,
financial or other information on which we base our decisions regarding use of
the net proceeds from this offering, and we may spend those proceeds in ways
with which you may disagree. Pending any of these uses, we will invest the net
proceeds of this offering in short term instruments, government securities and
other cash equivalents. We cannot predict whether any of these uses or
investments will yield a favorable return.

There is no trading market for our common stock, and you may not be able to
sell your shares at or above the initial offering price.

   This is the initial public offering of our common stock, and there is
currently no public market for our common stock. We cannot assure you that an
active trading market

                                       19
<PAGE>

will develop or will be sustained after this offering is complete. The initial
public offering price will be determined through negotiations between our
underwriters and us based on several factors and may not be the market price of
the common stock after the offering.

The price of our common stock may be subject to volatility, and this may
depress our stock price. We may be subject to lawsuits as a result of
fluctuations in our stock price.

   The market price of our common stock may be highly volatile, as is the stock
market in general, and the market for telecommunications and Internet-related
companies, in particular, has been highly volatile. The market price of our
common stock is also likely to be affected by our quarterly operating results,
which may vary in the future. Investors may not be able to resell their shares
of our common stock following periods of high volatility because of the
market's adverse reaction to that volatility. The trading prices of shares of
many telecommunications and Internet-related companies have reached historical
highs within the last 52 weeks and have reflected relative valuations
substantially above historical levels. During the same period, prices for the
shares of these companies have been highly volatile and many have recorded lows
well below their historical highs. We cannot assure you that our common stock
will trade at the same levels as other telecommunications and Internet-related
stocks or that stocks of such companies in general will sustain their current
market prices.

   Factors that could cause volatility in the market price of our stock
   include:

  .  actual or anticipated variations in operating results;

  .  announcements of technological innovations or problems;

  .  changes in financial estimates by securities analysts;

  .  conditions and trends in the telecommunications, Internet and data
     industries;

  .  legislative or regulatory developments;

  .  announcements by us or our competitors of significant acquisitions,
     strategic partnerships or joint ventures;

  .  additions or departures of key personnel; and

  .  sales of additional shares of our common stock.

   Many of these factors are beyond our control and may materially and
adversely affect the market price of our common stock, regardless of our
operating performance.

   Following periods of high volatility in the market price of a company's
securities, securities class action litigation is occasionally instituted. If
this were to happen to us, even if the claims were without merit, the
litigation would be expensive and would divert management's attention from the
operation of our business.

A third-party could be prevented from acquiring your shares of common stock at
a premium to the market price because of our anti-takeover provisions.

   There are provisions in our certificate of incorporation and bylaws that
make it more difficult for a third-party to acquire, or attempt to acquire,
control of NETtel, even if a

                                       20
<PAGE>

change in control would result in the purchase of your shares at a premium to
the market price.

   These provisions include:

  .  the authority of our board of directors to issue "blank check" preferred
     stock;

  .  eliminating the ability of stockholders to act by written consent;

  .  eliminating the ability of stockholders to call a special meeting of the
     stockholders;

  .  an advance notice procedure for stockholder proposals to be brought
     before meetings of our stockholders; and

  .  requiring a super-majority stockholder vote to effect certain
     amendments.

   In addition, the Delaware General Corporation Law may also discourage
takeover attempts that have not been approved by our board of directors.

Future sales of our common stock may lower our stock price.

   If our existing stockholders sell a large number of shares of our common
stock, the market price of the common stock could decline significantly. The
perception in the public market that our existing stockholders might sell
shares of common stock could depress our market price. Immediately after this
offering, approximately       shares of our common stock will be outstanding.
Of these shares,       of the shares will be available for immediate resale in
the public market. The remaining         shares, or      percent of our total
outstanding shares, will become available for resale in the public market after
180 days from the date of this prospectus subject, in some cases, to volume
limitations. However, the underwriters may waive this restriction and allow
these stockholders to sell their shares at any time.

   We have filed a registration statement on Form S-1 with the SEC under the
Securities Act of 1933, as amended, covering the common stock being offered by
this prospectus. As permitted by SEC rules, this prospectus omits certain
information that is included in the registration statement. For further
information about us and our common stock, you should refer to the registration
statement and its exhibits. Since this prospectus may not contain all the
information that you may find important, you should review the full text of

                           CAUTIONARY NOTE REGARDING
                           FORWARD-LOOKING STATEMENTS

   This prospectus includes forward-looking statements based on our current
beliefs and assumptions. These beliefs and assumptions are based on information
currently available to us. These forward-looking statements are subject to
risks and uncertainties. Forward looking statements include, but are not
limited to our anticipated deployment of sales offices and switches, statements
regarding the development of our business, the markets for our services and
products and information concerning our possible or assumed future results of
operations. You can generally identify forward-looking statements by the use of
words such as "believe," "expect," "may," "will," "should" or "anticipate" or
comparable terminology.

                                       22
<PAGE>

   Forward-looking statements are not guarantees of performance. Our future
results and requirements may differ materially from those described in the
forward-looking statements. Many of the factors that will determine these
results and requirements are beyond our control. In addition to the risks and
uncertainties discussed in "Prospectus Summary," "Business," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Government Regulation," you should consider those discussed under "Risk
Factors."

   These forward looking statements speak only as of the date of this
prospectus. Except as required by law, we do not intend to update or revise any
forward-looking statements to reflect events or circumstances after the date of
this prospectus, including changes in our business strategy or planned capital
expenditures, or to reflect the occurrence of unanticipated events.

                                USE OF PROCEEDS

   We estimate that we will receive net proceeds from this offering of
approximately $       million (approximately $      million if the
underwriters' over-allotment option is exercised in full) after deducting
underwriting fees and estimated expenses. We intend to use the net proceeds
from this offering to continue the deployment of Phase I of our network, to
continue the implementation of our operational support systems, to add direct
sales offices and Branchises in additional cities, for increased marketing and
for working capital and general corporate purposes, including funding operating
losses. We may also use a portion of the net proceeds for acquisitions, joint
ventures or strategic alliances, although we are not currently a party to any
contracts or letters of intent with respect to any such transactions. Pending
the application of the net proceeds to such uses, we intend to invest in short-
term instruments, government securities and other cash equivalents.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends on our common stock. We
plan to retain all of our earnings, if any, to finance the expansion of our
business and for general corporate purposes and do not anticipate paying any
cash dividends on our common stock for the foreseeable future. Our future
dividend policy will be determined by the board of directors on the basis of
various factors, including our results of operations, financial condition,
capital requirements and investment opportunities. Our credit agreement with
Nortel currently restricts our ability to pay dividends, and we anticipate that
any replacement senior secured facility would include a similar restriction.

                                    DILUTION

   The difference between the initial public offering price per share of our
common stock and the pro forma as adjusted net tangible book value per share of
our common stock after this offering constitutes the dilution to investors
purchasing our common stock in this offering. Net tangible book value per share
is determined by dividing our net tangible book value by the number of
outstanding shares of common stock. Net tangible book value equals total
tangible assets less total liabilities.

   Our deficit in pro forma net tangible book value as of March 31, 2000 was
$   million, or $     per share of common stock, after giving effect to the
conversion of our Series B Preferred Stock and to the issuance and conversion
of our Series C Preferred Stock. After giving effect to the sale of the
         shares of common stock upon completion of this offering, at the
initial public offering price of $       per share, and the conversion of our
preferred stock into common stock, our pro forma as adjusted net tangible book
value at March 31, 2000, would have been approximately $     , or approximately
$     per share. This represents an immediate increase of $      per share in
the pro forma net tangible book value to existing stockholders and an immediate
dilution of $       per share to new investors purchasing common stock in this
offering. The following table illustrates the per share dilution to new
investors:

   The foregoing table assumes no exercise of the underwriters' over-allotment
option and no exercise of options or warrants to purchase additional shares of
common stock. As of March 31, 2000, there were options outstanding to purchase
     shares of common stock at a weighted average exercise price of $   per
share. There are     warrants outstanding to purchase a total of     shares of
common stock at a weighted average price of $   per share; in addition, there
is one warrant outstanding to purchase 474,160 shares of common stock for $100.
To the extent outstanding options and warrants are exercised, there will be
further dilution to new investors.

    SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL AND OTHER DATA

  The following selected historical and pro forma consolidated financial and
other data should be read in conjunction with our consolidated financial
statements and related notes thereto and "Management's Discussion and Analysis
of Financial Condition and Results of Operations" presented elsewhere in this
prospectus. The selected financial data for the period from February 9, 1995
(inception) through December 31, 1995 and the fiscal years ended December 31,
1996, 1997, 1998 and 1999 are derived from our consolidated financial
statements, which have been audited by our independent auditors. Our
consolidated financial statements as of December 31, 1998 and 1999 and for each
of the three years in the period ended December 31, 1999 are included elsewhere
in this prospectus. The financial data set forth for the year ended December
31, 1996 and for the period from inception through December 31, 1995 are
derived from our audited financial statements not included in this prospectus.

  EBITDA consists of net income (loss) excluding net interest, taxes,
depreciation and amortization. EBITDA is provided because it is a measure of
financial performance commonly used in the communications industry, and it is
used by our management to measure our performance. We have presented EBITDA to
enhance your understanding of our operating results. You should not construe it
as an alternative to operating income, as an indicator of our operating
performance, as an alternative to cash flows from operating activities or as a
measure of liquidity determined in accordance with generally accepted
accounting principles. We may calculate EBITDA differently than other
companies. For further information, see our financial statements and related
notes elsewhere in this prospectus.

  The pro forma balance sheet data as of December 31, 1999, gives effect to the
issuance of our Series C Preferred Stock as if our Series C Preferred Stock was
issued on that date. The pro forma as adjusted balance sheet data as of
December 31, 1999, gives effect to the above and to the issuance and sale of
                 shares of common stock in this offering and the automatic
conversion of our preferred stock into common stock as if the issuance and the
conversion occurred on December 31, 1999. The operating results for the year
ended December 31, 1999, are not necessarily indicative of the results to be
expected for any future period. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

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

   You should read the following discussion together with our consolidated
financial statements and the notes to our financial statements presented
elsewhere in this prospectus. This prospectus contains forward-looking
statements that involve risks and uncertainties. Our actual results may differ
materially from those projected in the forward-looking statements. Please see
"Cautionary Note Regarding Forward-Looking Statements" on page 22. Our fiscal
year ends December 31.

Overview

   We offer medium-sized business customers an integrated package of high-speed
communication services, including broadband Internet, local and long distance
services and a suite of value-added data and voice communications applications,
including Web hosting, virtual private networks using Internet Protocol and
frame relay. We market our services through a highly trained multi-channel
sales force of approximately 250 sales professionals located in 21 markets
nationwide. The packet-switched architecture of our IP/ATM network allows our
sales force to offer an "integrated T-1" which enables our customers to
economically combine their data and voice communications usage on a single
broadband connection. We introduced this service and began delivering it to our
customers in the first quarter of 2000. We expect that demand for this service
will continue to increase as the demand for increased data access speed and
bandwidth accelerates.

   In January 1999, we began focusing our customer acquisition strategy and
selling broadband Internet and long distance services to medium-sized business
customers through all three of our sales channels. Our strategy was to begin
providing these services by reselling the Epoch network for Internet service
and the Frontier network for long distance service, while we constructed our
own data and voice network. In March 2000, we began soliciting customers for
our on-net local T-1 services in New York, Los Angeles, Chicago, Long Island
and Anaheim.

   Our integrated T-1 offering enables us to provide multiple services
(including Internet, local and long distance) and to easily migrate customers
onto our network. We also seek to significantly increase the value of our
current customer base by providing additional services over the dedicated
connection. These services today include local service in selected markets,
fully integrated T-1 connections and various value-added data and voice
services, including IP/VPN, Web hosting, frame relay, broadband Internet,
private line and DSL. We expect our percentage of on-net traffic to
significantly increase by the end of 2000.

   In early 1999, we completed construction of our first three switch sites in
New York, Chicago and Los Angeles. In June 1999, we purchased an indefeasible
right of use, or IRU, from Williams for the use of approximately 9,000 OC-3
fiber miles. In July 1999, we entered into a master purchase agreement with
Nortel whereby Nortel provides a turnkey solution for installing and
integrating our nationwide network. During the second half of 1999, we began an
aggressive effort to migrate our customers from resold dedicated and switched
long-distance service and resold Internet access to our own network and we have
moved a substantial portion of our traffic in these markets on-net.

                                       29
<PAGE>

   During the third quarter of 1999, we began installation of eight additional
switches. By March 31, 2000, we had installed 10 switches. We plan to complete
Phase I of our network deployment plan by the end of 2000, which will include
21 switches directly serving 26 markets where we have or expect to have a sales
force. Upon the completion of Phase I of our plan, we expect that most of the
customer traffic in our current markets will be carried on our network. Under
Phase II of our plan, we plan to install 12 additional switches. Our multi-
phase strategy has been designed around deploying a critical mass of sales and
network infrastructure based on the amount of capital available to fund the
growth of the business.

Revenue

   As noted above, we currently provide our medium-sized business customers
with an integrated broadband communications solution. We began focusing on this
customer segment and providing these services in the beginning of 1999.
Although broadband sales accounted for approximately 33% of our total revenue
in 1999, by the end of 2000 and thereafter we expect that the majority of our
revenue will be generated from the sale of broadband data and voice services to
medium-sized business customers.

   Our revenue is primarily generated from the sale of broadband Internet and
other data, local and long distance voice services. The revenue we generate
from broadband Internet and other data services consists primarily of monthly
recurring charges for connections from end-users to our facilities. We earn
revenue from local calling services through payments from monthly recurring
charges for basic service, usage charges for local calls and service charges.
Our revenue from long distance services includes payments for a full range of
long distance services, including traditional switched and dedicated long
distance and toll-free calling, in addition to international, calling card and
operator services.

   Our revenue prior to 1999 was primarily generated from reselling long
distance services provided by other carriers. Also, prior to 1999, most of our
customers were small businesses and home office customers; however, we expect
this customer base to significantly decrease as we continue to de-emphasize
servicing these customers.

Cost of Revenue

   Cost of revenue consists of direct costs associated with providing Internet
and telecommunications services to our customers. These costs specifically
include: (i) resale costs for Internet and long-distance customers not yet
served by our broadband network; (ii) costs to interconnect and terminate
traffic with other network providers; (iii) Internet access costs associated
with providing access to our customers; and (iv) other direct costs associated
with the origination, transportation and termination of our data and voice
traffic. As we transfer more of our traffic onto our own network, we believe
that our cost of revenue will decrease as a percentage of total revenue.

Selling, General and Administrative Expenses

   Costs associated with the promotion, marketing and sale of our services
include compensation and commissions paid to our direct sales force, Branchises
and independent agents, as well as advertising and marketing costs associated
with the development and

                                       30
<PAGE>

distribution of our services and building the NETtel brand. In addition to
these costs, we incur costs for network engineering services, customer care,
operational support systems and other administrative functions. As we expand
into new markets, we expect that our costs related to the promotion, sale and
marketing of our services will increase. In addition, as we continue to grow,
we anticipate we will need more personnel in the customer care and network
management functions, which will result in increased costs. We also expect to
continue to incur significant costs with respect to the implementation and
enhancement of our operational support systems.

Capital Expenditures

   The development and expansion of our business, including the deployment of
our network and our operational support systems, will require significant
capital expenditures. The majority of our capital expenditures to date include
fiber capacity, data and voice communications switches and switch-related
equipment. In June 1999, we purchased an IRU from Williams for the use of
approximately 9,000 OC-3 fiber miles. Future capital expenditures for switches
and switch-related equipment will continue to increase as we expand our network
and provide a broader coverage area throughout the United States. In addition
to these network-related capital expenditures, we have also incurred, and will
continue to incur, costs for the purchase and development of operational
support systems, such as billing, customer care, order entry and provisioning.
We believe that a significant portion of the development and implementation
costs for these systems will be incurred prior to December 31, 2000.

Depreciation

   Depreciation expense includes depreciation of network equipment and related
infrastructure and improvements to corporate facilities. As we expand our
operations and deploy our network, we expect depreciation expense to
significantly increase.

Results of Operations

Year Ended December 31, 1999 Compared to Year Ended December 31, 1998

   Revenue was $31.4 million for the year ended December 31, 1999, compared to
$13.2 million for the year ended December 31, 1998, representing an increase of
approximately 137.5%. This increase, all due to internal growth, is
attributable to our new focus on providing broadband data and voice services to
medium-sized business customers and our expansion of full-scale operations in
12 primarily Tier I and Tier II markets during 1999. We also generated
significantly more broadband revenue during 1999, which includes dedicated data
and voice services. This revenue represented approximately 33.2% of our total
revenue in 1999, as compared to less than 1.0% in 1998.

   Cost of revenue was $22.3 million, or 70.9% of revenue, for the year ended
December 31, 1999, compared to $9.9 million, or 75.0% of revenue, for the year
ended December 31, 1998. During 1999, we began migrating a portion of our
customer traffic onto our own network, which accounted for the decrease in cost
of revenue as a percentage of revenue. As we shift more of our customers and
traffic onto our network, we anticipate that the cost of revenue will continue
to decrease as an overall percentage of revenue.

                                       31
<PAGE>

   Selling, general and administrative expenses were $53.7 million, or 171.1%
of revenue, for the year ended December 31, 1999, compared to $23.8 million, or
179.6% of revenue, for the year ended December 31, 1998, representing an
increase of approximately 126.3%. This increase resulted primarily from
increased overall headcount and headcount-related expenses, as we added
employees in all departments. Our employee work force grew from approximately
295 at the end of 1998 to approximately 385 at the end of 1999. Most new hires
during 1999 were for back office positions, such as marketing, customer care,
operational support systems and finance and accounting.

   Depreciation and amortization was $2.8 million for the year ended December
31, 1999, compared to approximately $321,000 for the year ended December 31,
1998. This increase was primarily attributable to higher capital expenditures
in 1999, including the purchase of the IRU from Williams in June 1999.

   Interest expense, net of interest income, totaled $2.7 million for the year
ended December 31, 1999, compared to net interest income of approximately
$79,000 for the year ended December 31, 1998. This increase was attributable to
higher debt balances outstanding during 1999.

   The net loss increased to $50.1 million for the year ended December 31,
1999, compared to $20.7 million for the year ended December 31, 1998, for the
reasons discussed above.

   We also accrued preferred dividends of approximately $1.7 million with
respect to the Series B Preferred Stock we issued in 1999.

Year Ended December 31, 1998 Compared with Year Ended December 31, 1997

   Revenue was $13.2 million for the year ended December 31, 1998, compared to
$3.7 million for the year ended December 31, 1997, representing an increase of
approximately 261.1%. This increase was principally due to the beginning of our
selling services to business customers through our direct, Branchise and
independent agent channels in January 1998. During the year ended December 31,
1998, business customers generated the majority of overall revenue.
Substantially all of our revenue during 1997 was derived from sales to
residential customers.

   Cost of revenue was $9.9 million, or 75.0% of revenue, for the year ended
1998, compared to approximately $2.5 million, or 68.3% of revenue, for the year
ended December 31, 1997. This increase was due primarily to our shift in early
1998 from our focus on residential customers to business customers.

   Selling, general and administrative expenses were $23.8 million, or 179.6%
of revenue, for the year ended December 31, 1998, compared to $3.1 million, or
84.6% of revenue, for the year ended December 31, 1997. This increase was due
to substantial increases in the number of direct sales force professionals,
increased marketing programs and associated salaries and other headcount-
related expenses.

   The net loss was $20.7 million for the year ended December 31, 1998,
compared to $2.1 million, for the year ended December 31, 1997.

Liquidity and Capital Resources

   We have made significant capital investments to deploy our network and
develop our operational support systems. Additional capital will be required to
continue to expand our network, implement our operational support systems,
increase our customer base and fund operating losses. Future capital
expenditures for switches and switch-related equipment, including site
construction costs, to complete Phase I of our network deployment will be
significant. We expect capital expenditures of approximately $60 million for
the last three quarters of 2000 and approximately $21 million during 2001 in
order to complete our Phase I deployment. We believe that the net proceeds from
this offering, along with amounts available under a credit agreement we have
with Nortel and other vendor financing and cash generated from our operations,
will be sufficient to meet our planned capital requirements for Phase I of our
network deployment and to fund our anticipated operating losses for that phase.
However, if we choose to enter additional markets, enter markets earlier than
currently anticipated or make acquisitions, or if we exceed market penetration
estimates, then we may require additional capital to continue our growth and
operating plans. If we fall significantly short of our estimates for operating
and financial performance, we may also require more capital. Furthermore, we
may need additional financing for future capital expenditures to implement our
business plan, which includes constructing our network and our operational
support systems; offering new broadband communications services; and paying
scheduled principal and interest payments on our debt. We will need to raise
significant additional capital in order to fund Phase II of our network.

   Our funding to date has come from a variety of sources, including venture
funds focused on the communications industry and from strategic investors. In
August 1999, we completed a series of debt and equity transactions with
Williams, Nortel, Allied and Gold & Appel to fund the initial portion of Phase
I of our network and the expansion of our operational support systems. Prior to
consummating those transactions, our funding was provided principally by Gold &
Appel and Atocha, L.P., certain equipment vendors and by financing our
receivables.

   Gold & Appel Transfer, S.A. and Atocha, L.P.

   In February 1998, we issued common stock to Gold & Appel and Atocha, in
exchange for an investment of $10.0 million. In June of 1998, we sold
additional common stock for an additional $10.0 million cash investment. Gold &
Appel and Mr. Kenefick subsequently acquired all of Atocha's shares.

   In September 1998, we entered into a revolving line of credit with Gold &
Appel for $12.0 million. Interest accrued on unpaid balances at a rate of
12.25% per annum. During 1999, a total of $12.4 million was converted into
additional shares of our common stock. In April 1999, we entered into a
revolving bridge loan with Gold & Appel for up to $8.0 million. Interest
accrued on unpaid balances at a rate of 12.0% per annum. We borrowed a total of
$8.0 million under the Gold & Appel bridge loan, and the entire outstanding
principal balance of the loan was converted to Series B Preferred Stock in July
1999.

   Williams Communications, Inc.

   On June 28, 1999, we entered into a securities purchase agreement and a
long-term Capacity Purchase Agreement with Williams. The Capacity Purchase
Agreement grants us a twenty-year IRU for capacity on Williams' network valued
at approximately $60.0 million. We paid the net present value of approximately
$25.0 million for the IRU, paying $5.0 million in the form of network credits
when we executed the Capacity Purchase Agreement and committing to pay the
balance over a seven-year term with interest at 12.0% per annum. Under the
Securities Purchase Agreement, we issued shares of Series A Preferred Stock in
exchange for $5.0 million in cash and $5.0 million in network credits, which
were used in the initial payment for the IRU. The Series A Preferred Stock was
converted into Series B Preferred Stock at the closing of the Series B
Preferred Stock offering in July 1999.

   Nortel Networks Inc.

   In July 1999, we entered into a Securities Purchase Agreement with Nortel,
under which we issued shares of our Series B Preferred Stock in exchange for a
$20.0 million cash investment. We also entered into a Credit Agreement,
consisting of a $120.0 million Advancing Term Loan Facility, a $10.0 million
Revolving Credit Facility and a $10.0 million term loan from Allied (described
below). For every dollar borrowed to fund Nortel products and services, we can
borrow an additional 50 cents under the Advancing Term Loan Facility to pay for
other capital expenditures and operating costs related to the build-out of our
network. The Revolving Credit Facility is for working capital and general
corporate purposes, borrowings against which are based on the balance of our
eligible accounts receivable, as defined in the Credit Agreement. Borrowings
under the Credit Agreement are secured by a first priority lien on all of our
assets.

   We may use the Advancing Term Loan Facility to pay for products and services
provided by Nortel until August 2001, and we are required to repay such
borrowings over a five-year period thereafter. Based on the level of borrowings
at March 31, 2000, principal payments are scheduled to begin in the fourth
quarter of 2001. The Credit Agreement includes customary affirmative and
negative financial, operating and other covenants and events of default,
including covenants requiring us to meet specified EBITDA, revenue, capital
expenditure and debt service targets. Covenants in the Credit Agreement also
limit our ability to incur additional indebtedness and restrict our ability to
pay cash dividends and make other distributions to stockholders.

   The Credit Agreement permits us to designate all or any portion of the
borrowings as either a floating base rate advance, with an applicable margin of
3.5%, or a Eurodollar rate advance, with an applicable margin of 4.5%. Interest
on base rate loans is due monthly. Interest on Eurodollar loans is due at the
end of the applicable loan period. Borrowings under the Credit Agreement
carried interest at rates ranging from 10.15% to 10.68% as of December 31,
1999. As of March 31, 2000, we were permitted to borrow up to an additional
$80.9 million under the Credit Agreement. We have also agreed to issue warrants
for 222,961 shares of our common stock to Nortel under certain circumstances
but only if this offering is not consummated by October 31, 2000.

                                       34

   Allied Capital Corporation

   In August 1999, as part of the Credit Agreement with Nortel, we entered into
a term loan agreement with Allied. We borrowed $10.0 million from Allied,
bearing interest at 12.0% per annum, with interest payable monthly. The Allied
loan matures on July 30, 2006. In connection with the Allied loan, we issued a
warrant to purchase 474,160 shares of our common stock for a nominal amount.
The value of the warrant is reflected as a discount to the debt and an increase
to additional paid-in capital, and is being amortized over the life of the loan
through a charge to interest expense.

   We also issued shares of our Series B Preferred Stock to Allied in exchange
for a $5.0 million cash investment.

   Capital Leases

   We have entered into a number of capital lease arrangements for the purchase
and use of network, computer and office equipment. Total balances outstanding
under capital leases at December 31, 1999 were approximately $4.2 million.
Assets obtained under capital leases had an original cost of approximately $4.9
million. These leases are of varying terms, and we intend to continue to
utilize capital lease arrangements as we continue to grow our business.

   Series B Preferred Stock

   In July and August 1999, in a private placement, we issued Series B
Preferred Stock to each of Gold & Appel, Nortel and Allied, as described above.
In addition, at the closing of these transactions, Williams converted the
Series A Preferred Stock to Series B Preferred Stock. The Series B Preferred
Stock is entitled to cash dividends of 8.0% per annum, which may be paid in the
form of additional shares of Series B Preferred Stock at our option.

   The Series B Preferred Stock has provisions entitling the holders to convert
the value of their stock into shares of common stock at any time based upon an
initial conversion price of $7,730 per share ($7.73 per common stock equivalent
share), subject to certain anti-dilution provisions. Upon closing an initial
public offering, as defined, the shares of Series B Preferred Stock plus 50.0%
of any unpaid dividends convert into shares of common stock. The remaining
dividends are either payable in cash or shares of common stock at our option.
If, on or before the seventh anniversary of the issuance date, we have not
completed an initial public offering, a liquidation or a sale of our company,
then the holders of the Series B Preferred Stock have the right to redeem their
shares for cash equal to $7,730 per share, subject to adjustment, plus all
accumulated and unpaid dividends thereon.

   Series C Preferred Stock

   On April 20, 2000, in a private placement, we issued 1,362,089 shares of
Series C Preferred Stock for $10.0 million in cash to Gold & Appel, Nortel,
Allied, and The Foundation for the International Non-Governmental Development
of Space, and $2.0 million from Williams in the form of a credit against
current year

                                       35
<PAGE>

payments on our Capacity Purchase Agreement. The Series C Preferred Stock is
entitled to dividends of 8.0% per annum, with half the accrued and unpaid
dividends payable in cash and half payable in the form of additional shares of
Series C Preferred Stock upon conversion, which occurs automatically upon the
consummation of an initial public offering with at least $25.0 million in net
proceeds to us.

   Loan Agreement with Gold & Appel

   On April 13, 2000, we entered into a $35.0 million loan agreement with Gold
& Appel. We may borrow funds under the loan agreement at any time from July 5,
2000 until the earlier of July 5, 2001 or the closing of this offering. Amounts
outstanding under the loan agreement bear interest at a rate of 12.0% per
annum. Amounts outstanding under the loan agreement may be converted at the
election of holders of 75% of our Series B Preferred Stock into common stock at
a price per share which is equal to the conversion price per share of any
convertible preferred stock (or the price per share of any common stock) we
issue between April 13, 2000 and the closing of this offering. Amounts
outstanding under the loan agreement may be repaid at any time, but must be
repaid upon the earlier of July 5, 2001 or the closing of this offering.

   Historical Cash Flows

   For each of the three years in the period ended December 31, 1999, we used
cash in our operations of approximately $36.8 million, $17.6 million, and $1.9
million, respectively, consisting primarily of our net loss offset by
depreciation expense and changes in certain operating asset and liability
amounts. We expect to continue to use cash in our operations through the end of
2001.

   Cash used in investing activities in each of the three years ending December
31, 1999 was approximately $12.9 million, $4.5 million, and $42,000,
respectively, consisting solely of cash used for capital expenditures. In
addition to the cash used in 1999, we also have obtained another approximately
$40.8 million of assets through financing arrangements, including the Williams
strategic partnership ($24.8 million), the Nortel Term Loan ($12.1 million) and
various capital leases ($3.9 million).

   Cash from financing activities was approximately $71.3 million in 1999,
consisting of $35.6 million in proceeds from the various debt arrangements
discussed above, $36.7 million in net proceeds from the issuance of the Series
B Preferred Stock, and $0.5 million from the issuance of common stock. These
amounts were offset by payments on debt obligations of approximately $1.5
million in 1999. In 1998, cash from financing activities was $22.9 million,
primarily consisting of proceeds from the issuance of common stock and the
reissuance of treasury stock. In 1997, cash from financing activities was
approximately $1.9 million, consisting of net proceeds on a line of credit and
proceeds from the issuance of common stock.

   Our working capital was approximately $3.6 million at December 31, 1999,
compared to a deficit of approximately $2.5 million at December 31, 1998. The
increase primarily is due to increased cash balances on hand at December 31,
1999 from the capital raised in the debt and Series B Preferred Stock
transactions.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("SFAS No. 133"). SFAS No. 133 is effective for fiscal years
beginning after June 15, 2000, and cannot be applied retroactively. SFAS No.
133 establishes accounting and reporting standards, requiring that every
derivative instrument be recorded in the balance sheet as either an asset or
liability measured at its fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. The Company plans to adopt SFAS No. 133
effective January 1, 2001.

   In June 1999, the FASB issued Interpretation No. 43, "Real Estate Sales, an
interpretation of FASB Statement No. 66." The interpretation is effective for
sales of real estate with property improvements or integral equipment entered
into after June 30, 1999. Under this interpretation, dark fiber is considered
integral equipment and accordingly title must transfer to a lessee in order for
a lease transaction to be accounted for as a sales-type lease. After June 30,
1999, the effective date of FASB Interpretation No. 43, sales-type lease
accounting is no longer appropriate for dark fiber leases and therefore the
Company's future dark fiber transactions will be accounted for as operating
leases unless title to the fibers under lease transfers to the Company.

Year 2000

   In late 1999, we completed a program of testing and remediation of our
systems with respect to their ability to process dates from January 1, 2000 and
beyond. Because of these efforts, we experienced no significant disruption in
our operational support and other systems, and we believe that these systems
successfully responded to the year 2000 date change. Our efforts did not
require a significant commitment of resources or expense. We are not aware of
any material problems resulting from year 2000 issues, either in respect to our
service offerings, operational support and other systems, or the products and
services of third parties used in our business. We will continue to monitor our
operational support and other systems, as well as those of our third-party
vendors, throughout 2000 in order to promptly address any latent year 2000
matters.

Quantitative and Qualitative Disclosure About Market Risk

   We do not have operations that are subject to risk arising from foreign
currency fluctuations, and we do not use derivative financial instruments in
our operations or investment portfolio (although Nortel, as the administrative
agent under our credit agreement, may require us to enter into hedging
transactions with respect to the interest payments we make under the credit
agreement). Our earnings are affected by changes in interest rates, because a
significant portion of our indebtedness under the credit agreement bears
interest at a variable rate that is based upon either the prime rate or LIBOR.
If interest rates for this indebtedness increase 1/8% during 2000 as compared
to 1999, our interest expense would increase by approximately $270,000, and our
loss before taxes would increase by the same amount. These amounts are
determined by considering the impact of the hypothetical interest rates on our
cost of borrowing and anticipated indebtedness.

                                    BUSINESS

Overview

   We are a nationwide integrated communications provider using state-of-the-
art technology and a solutions oriented, face-to-face sales approach focused on
medium-sized business customers. We believe that our competitive advantages are
our experienced, data-oriented nationwide sales force, our integrated
operational support systems and our nationwide integrated data and voice
network. We currently offer an integrated or bundled package of broadband
Internet, local and long distance services and a suite of value-added data and
voice communications applications, including Web hosting, virtual private
networks using Internet Protocol and frame relay. We deliver these services and
applications primarily over a broadband T-1 connection, or in some cases, over
a digital subscriber line, called a DSL, connection.

Business Strategy

   The key elements of our strategy are to:

   Focus on Medium-sized Business Customers. Our medium-sized business
customers typically have limited information technology resources and do not
have a full-time communications professional. We have also found that many of
our target customers have been under-served by other carriers and have been
unable to purchase integrated services from a single vendor. Therefore, our
target customers respond favorably to our consultative, solutions-oriented,
face-to-face sales approach and the value proposition of our integrated
broadband services offering. We estimate that our target customers will account
for approximately 15% of the $295 billion data and voice communications market
during 2000. By focusing our efforts on medium-sized business customers and
offering them integrated communications services designed to meet all of their
data and voice communications needs, we believe we will continue to achieve
rapid revenue growth.

   Offer Integrated Communications Services Using a Single Broadband
Connection. We provide an integrated bundle of communications services,
including broadband Internet, local and long distance services and a suite of
value-added services such as Web hosting, virtual private networks using
Internet Protocol and frame relay. We deliver these services and applications
over either an integrated broadband T-1 or, in some cases, a DSL connection. We
believe our target customers purchase our "integrated T-1" because it offers a
better value proposition by delivering data and voice communications over a
single dedicated line while other carriers' networks require customers to
purchase these services over multiple lines. We bill our services using a
single electronic invoice or, if the customer prefers, by mail. We are
currently developing various additional service offerings, including unified
messaging services, remote local area network access services, Web site and e-
commerce development, enhanced Internet applications services, managed network
services and application hosting services.

   Capitalize on Multiple Sales Channels. We market to our target customers
through proven nationwide sales channels, including direct sales, Branchises
and independent agents, to maximize our selling efforts. As of March 31, 2000,
we had 200 direct sales

                                       38
<PAGE>

professionals in 15 sales offices, 11 Branchises with approximately 50 sales
representatives and an additional 25 independent agents; together, these sales
channels serve a total of 21 markets. Each channel has been designed to scale
quickly through a combination of proven business processes and training
techniques. Our sales force has been selling broadband Internet and long
distance service since January 1999 and began selling local service in New
York, Chicago, Los Angeles, Long Island and Anaheim in March 2000. As we
introduce local service in other markets, and as we offer additional services,
we expect to realize significantly increased revenue from our existing customer
base and to secure larger initial sales from new customers. By the end of 2000,
we also expect to open six additional direct sales offices, enter into 10
additional Branchise relationships and recruit seven additional agent sales
managers.

   Implement Integrated Operational Support Systems. We have developed and are
continuing to implement our integrated operational support systems that can
scale to support our anticipated rapid growth. Our operational support systems
synchronize multiple tasks, including order entry, service installation,
billing, customer care, network management and financial reporting. Unlike the
legacy systems of other carriers, our systems will allow a seamless flow of
customer information from sales to service to billing. This capability will
shorten our provisioning cycle, expedite service to the customer and enhance
our customer care. We are also implementing an electronic interface, referred
to as electronic bonding, linking our operational support systems directly to
Ameritech, Bell Atlantic, Pacific Bell and other established telephone
companies to automate the provisioning of customers onto our network. Our
approximately 50 systems professionals are continually refining the integration
of these systems, adding new enhancements and incorporating new technology to
improve our customers' experience and our own operations.

   Provide Superior Customer Care. We strive to provide one call resolution
capability to all of our customers to resolve any customer issue, ensure
customer satisfaction and maximize retention rates. Under this approach, our
customer care representatives, known as CCRs, are the single point of contact
for our customers, and they are accountable for resolving any customer issue,
including ordering, provisioning, network repair or billing. The CCRs have
access to an integrated and centralized database that contains all of our
customers' information, which allows us to provide our customers with accurate
and up-to-date status reports. The CCRs are located in the same facility as our
provisioning, credit analysis and billing support groups, giving them direct
and immediate access to the personnel with the expertise to solve customer
service issues as they arise.

   Deploy an Integrated and Flexible Nationwide Network. We employ a "smart
build" strategy, installing integrated data and voice switches, purchasing long
haul fiber and leasing local fiber where we have, or plan to have, a sales
presence. Owning these components of our packet-switched network enables us to
enhance the quality of our service offerings and accelerate the implementation
of new technologies as they become available. As of March 31, 2000, we have
installed 10 packetized switches, and we intend to install 11 additional
switches during 2000. At the end of Phase I, our packet-switched network will
include switches in 21 cities, serving 26 markets where we have or expect to

                                       39
<PAGE>

have a sales force. In addition, we entered into a strategic partnership with
Williams and purchased approximately 9,000 OC-3 fiber miles to connect all of
our switches. Through this strategic partnership with Williams, we can service
customers in markets where our traffic does not yet justify installing a
switch. Currently, this will enable us to reach customers in 14 additional
markets.

   Develop Advanced Service Offerings and Applications Through Strategic
Relationships. We partner with companies that provide leading data and voice
applications to offer comprehensive communications solutions to our customers.
We believe the commercial distribution of advanced service offerings and
applications can be achieved in three ways: by building the application
internally, by partnering with third parties or by purchasing applications for
integration into our service offerings. While we may develop certain products
and services internally, we believe there are a large number of applications
and advanced service offerings offered by other companies that will be valuable
to our customers. We intend to partner with these companies, acting both as a
network to host and deliver their applications and as a distribution channel to
reach end-users. We believe that by owning the customer relationship and the
network platform and partnering with third parties to provide advanced service
offerings and applications, we will most efficiently deploy our capital and
maximize the value of our investments.

   Benefit from Experienced Management and Sponsorship. We believe that the
quality of our senior management is critical to the successful implementation
of our business plan. Each of our top 15 executives have an average of over 15
years' experience in the communications industry. These executives have
significant experience in marketing, sales, customer care, operations, network
deployment and finance at major Internet, local and long distance companies,
such as MCI Metro, Level 3 Communications, IBM Global Networks, Epoch Networks,
Qwest International, Bell Atlantic, MCI WorldCom, AT&T, Cable & Wireless and
Frontier Communications/Allnet Communications.

   We also benefit from the experience of our outside directors and equity
sponsors. Our outside directors have extensive experience developing
competitive Internet and telecommunications companies, such as Erols' Internet,
Epoch, LCI International, Esprit Telecom Group PLC and Qwest. Our equity
sponsors include: Gold & Appel Transfer, SA, a venture capital fund
specializing in communications; Allied Capital Corporation, a publicly-traded
finance company; Nortel, a leading network equipment provider; and Williams, a
national wholesale fiber optic capacity provider.

Strategic Relationships

   We believe that, in order to provide a comprehensive and integrated suite of
data and voice services over a single network, it is critical to enter into
strategic relationships. In order to rapidly deploy our network, we have
entered into alliances with Williams and Nortel, whom we believe to be the
market leaders for communications network and equipment.

   With Williams, we entered into a 20 year $25 million IRU for approximately
9,000 miles of OC-3 fiber capacity. In return, Williams committed to purchase
$10 million of

                                       40
<PAGE>

equity, consisting of $5 million in cash and $5 million in network credits, and
to finance the $20 million balance of the purchase price for the IRU. We also
collocate certain of our network equipment in Williams' facilities, use the
Williams network to extend our own network, have access to Williams' senior
management for strategic and network planning and have use of their testing lab
to evaluate new technology before adopting it.

   Our partnership with Nortel has provided us with a turnkey solution for our
nationwide network deployment. We were the first company to carry traffic
successfully over Nortel's ATM Passport switch. Nortel has invested $20 million
in equity and provided us with a $130 million credit facility. As technology
evolves and new network products and equipment are developed, our arrangement
with Nortel allows us to migrate to next generation technologies as they are
introduced and receive significant purchase credits for the equipment we
replace.

   We intend to pursue partnerships with additional companies that can help us
to leverage our sales force, network and systems infrastructure to provide our
customers with a comprehensive data and voice solution. We believe our
strategic relationships with Nortel and Williams have enabled us to quickly
deploy a nationwide integrated network and will allow us to continue to deliver
state-of-the-art solutions to our customers.

Market Opportunity

Data and Voice Communications Market Size and Growth

   Our integrated T-1 service offering can be used by a customer for either
data or voice traffic, or a combination of both. The deregulation of the
telecommunications industry and the increasing demand for Internet and related
data transmission services have created a significant market opportunity for
competitive providers of data and voice telecommunications services.

Targeted Customers

   We believe that within the data and voice communications market, our most
attractive opportunity consists of medium-sized businesses. We estimate that
these target customers will account for approximately 15% of the $295 billion
communications market during 2000. Medium-sized businesses have historically
been under-served by incumbent carriers, who we believe have generally found
that it is not cost-effective to dedicate a significant amount of resources to
service these customers. In order to obtain a full package of Internet, data
and voice services, our target customers have generally had to purchase
services from several different service providers, internally integrate the
services and receive and reconcile the bills from each service provider. We
believe that our ability to offer integrated data and voice services over a
single broadband connection as well as our simplified billing and high quality
customer care will provide us a significant competitive advantage to meet the
needs of medium-sized businesses.

Services

   We offer bundled communications solutions tailored to meet the needs of
medium-sized business customers. Our integrated IP/ATM network enables us to
provide our customers with a variety of competitively priced data and voice
service offerings. Our current offerings include the following:

                               Current Offerings

      Data Services                            Voice Services

      Broadband Internet                       Local Voice Services
      IP/Virtual Private Networks              Long Distance Voice Services
      Web Hosting
      Frame Relay
      Private Line
      DSL Internet Access
      Dial-up Internet Access

Integrated Access

   We offer integrated broadband Internet, local access and long distance voice
services and applications over a single T-1 connection using our IP/ATM
network. This product enables customers that currently are using multiple
vendors for their core Internet, local and long distance services to realize
increased connectivity speeds, reduced costs, simplified billing and improved
customer care. This service also enables customers that have multiple broadband
connections for each of their core communication services to consolidate their
services on fewer dedicated connections and realize immediate savings by paying
for fewer local loops.

   Data Services

  .   Broadband Internet. Our customers can purchase bandwidth on either a
      metered use basis at speeds ranging from 56Kbps up to 1.544 Mbps (T-
      1), or a fixed price basis at speeds ranging from 56Kbps to 45 Mbps
      (T-3). The metered service offering provides the advantages of
      allowing customers to only pay for the bandwidth that they use, while
      at the same time "capping" the cost at the same price as the fixed
      price alternative if they need the full T-1 capacity.

        We believe that another competitive advantage of our broadband
    Internet service is that we provide all required equipment, local loop
    charges and usage for a single price. As most customers do not have
    suitable equipment on their premises, we have found that they respond
    favorably to our complete solution, which includes the configuration,
    installation and maintenance of all necessary customer premises
    equipment.

                                       43
<PAGE>

  .   Virtual Private Networks using Internet Protocol (IP/VPN). We offer
      our customers Virtual Private Networks allowing them to create a data
      network between their locations that is secure and reliable, with the
      added benefit of improved access to the public Internet from all
      locations. Using Internet Protocol, or IP, instead of dedicated point-
      to-point circuits, reduces a customer's fixed costs without
      sacrificing security or availability. Security levels match what
      customers have come to expect from traditional private lines by using
      a number of innovative technologies, such as sending encrypted data
      packages between locations and using customer premises equipment that
      places a physical barrier between traffic from the public network and
      the customer's internal network.

        We are able to remotely monitor network availability from our
    network management centers to ensure traffic is being properly routed
    and prioritized in relation to other traffic on the network. Our
    customers can combine our IP/VPN service on a single T-1 with local
    and long distance services to obtain peak optimization of their
    broadband capacity. Additionally, customers may transmit voice traffic
    over their internal VPN. We include the cost of the customer premises
    equipment, as well as the cost of the local loops, in our one-price,
    single-bill solution.

  .   Web Hosting. We offer a shared hosting solution for our customers to
      remotely manage their Web sites, e-mail and e-commerce. This service
      is currently being offered through a private label partnership.

  .   Frame Relay. Certain of our customers have equipment that cannot
      "handle" IP/ATM services. For these customers, we offer the ability to
      transmit their proprietary data traffic over a secure frame relay
      network. We offer our customers multiple service options, depending
      upon their usage pattern and need for guaranteed delivery times. We
      can either provide the required frame relay equipment or use their
      existing equipment.

  .   Private Line. This service provides high-speed and secure digital
      connectivity between customer locations for data and voice traffic.

  .   DSL Internet Access. We provide synchronous digital subscriber line,
      known as SDSL, service for high-speed Internet access over standard
      copper telephone lines. We consider SDSL more desirable for medium-
      sized businesses than other DSL options because it allows for the same
      data transfer rate in both directions and is well-suited for
      bandwidth-intensive applications such as Web hosting, file uploading
      and video conferencing. We plan to offer SDSL and dial-up Internet
      access nationwide in conjunction with our integrated access offerings
      to extend our network to smaller branch offices and telecommuters.
      These services will be provided through private-label partnerships
      with nationwide providers.

  .   Dial-up Internet Access. We provide private label Internet dial-up
      access for our corporate customers, enabling them to access our
      broadband network when traveling or working from home. Customers can
      use over 950 local access numbers within the United States and nearly
      1,500 global access numbers

                                       44
<PAGE>

      covering more than 150 countries. The service also includes 24 hour
      help desk support with toll-free number access.
   Voice Services

  .   Local Voice Services. In contrast to traditional telephone companies
      as well as many of our competitors, our broadband local services offer
      simplified rates and calling areas. We are connected to our customers
      through either their current private branch exchange, or PBX, digital
      access trunks or private direct inward and outward dial trunks. We
      provide all of the traditional and enhanced local services currently
      provided by the incumbent telephone providers. These services include:
      operator services, emergency 911, caller identification, three-way
      calling, call waiting, call transferring and call forwarding. We also
      originate and terminate interexchange carrier calls placed by our
      customers. In addition, we offer an integrated services digital
      network, primary rate interface, or ISDN PRI. By offering ISDN PRI, we
      can solve customer bandwidth allocation issues by dynamically
      reconfiguring PBX access to accommodate changes in bandwidth
      requirements and provide caller identification and routing services to
      the customer.

  .   Long Distance Services. We provide a comprehensive suite of domestic
      and international long distance services. Our customers can connect to
      our network via broadband access facilities, which can be integrated
      with data and local service. We offer a number of outbound and inbound
      (toll free) long distance packages that meet the needs of our
      customers, based on their calling volumes and number of locations
      served. Our service offerings include in-state and interstate calling
      for both intraLATA and interLATA calling. International termination is
      available to over 200 countries. These services are available via
      broadband access, switched access and calling card.

    Planned Services

  In order to enhance our communication solution for our customers, during
  2000 we plan to offer the following advanced service offerings and
  applications:

  .   Unified Messaging Services. We intend to offer our customers unified
      messaging services that allow users to retrieve and respond to voice
      mails and e-mails remotely by the telephone, email or the Internet.
      This service will be offered through a private label partnership. This
      partnership will be invisible to our customers, and the service can be
      ordered and managed over our secure customer Extranet site.

  .   Application Service Providers. We intend to host application service
      providers on our network, enabling our customers and third parties to
      access the underlying applications over our network.

  .   Web and E-Commerce Site Development. We plan to offer value-added Web
      and e-commerce services through several private label partnerships
      which will provide our clients with Web-enabled functions, such as on-
      line ordering, secure payment processing, procurement, inventory
      management and customer service.

                                      45
<PAGE>

  .   Enhanced Internet Applications Services. Our enhanced Internet
      application services will include Web-based and Web-managed e-mail
      services and hosted collaborative applications, such as on-line
      calendars, on-line meetings, virtual bulletin boards and document
      sharing.

  .   Managed Network Services. Our end-to-end product solutions will
      include design, installation and management of our clients' data and
      voice networks. These services will include de-marc extension, channel
      bank configurations and deployment, router configuration and
      deployment, network monitoring and managed firewalls.

  .   Wholesale Services to Internet Service Providers and Value Added
      Resellers. We believe that by rapidly deploying our IP/ATM technology
      throughout our target markets, we will capitalize on additional
      product and revenue opportunities that will enhance usage on our
      network. These opportunities include offering Internet and local
      services on a wholesale basis to other telecommunications companies,
      such as Internet service providers and value-added resellers, that
      desire to offer Internet access and local services, but do not have
      the resources or network facilities to provide these services. This
      allows these companies to market and resell our services under their
      own brand name while allowing us to leverage our network capabilities.

Sales Channels

   We have found that segments of the medium-sized business market have
different telecommunications needs and buying patterns and, therefore, respond
to different sales approaches. To most effectively reach these different
segments, we market our services through three principal sales channels: direct
sales, Branchise and independent sales agents.


                                       46

Direct Sales

   We have built an experienced and highly motivated direct sales force
consisting of over 200 sales professionals in 15 direct sales offices serving
15 markets as of March 31, 2000. The following table details our existing and
planned sales office locations for our Phase I network deployment as of March
31, 2000 and our anticipated staffing levels in these Phase I markets by
December 31, 2000. By the end of 2000, we intend to have approximately 330
sales professionals in 21 sales offices serving 22 markets.

(1) These offices also serve San Jose, CA and Oakland, CA.

Each sales office is led by a general manager who is responsible for attaining
office revenue targets. The general manager is supported by two sales managers
and a direct sales team, made up of five to seven people, with two distinct
roles: initial customer acquisition and customer relationship management.

  Customer Acquisition Team

   The following members of each customer acquisition team develop potential
target customers, pursue initial customer relationships and close product
sales:

  .   Major Business Analysts. Our Major Business Analysts typically have
      over five years of telecommunications sales experience and focus on the
      larger businesses with extensive and complex telecommunications needs.
      The Major Business Analysts also implement vertical marketing
      strategies for greater return on prospecting and qualifying potential
      customers in major markets.

                                       47
<PAGE>

  .   Senior Communications Analysts. Our Senior Communications Analysts, or
      SCAs, typically have one to three years of telecommunications sales
      experience and focus on delivering the full spectrum of data and voice
      services we offer. SCAs are also responsible for assisting in the
      training of Communications Analysts. In addition, SCAs meet with new
      customers to review and explain their first month's bill.

  .   Communications Analysts. Our Communications Analysts have up to a year
      of telecommunications sales experience and focus on delivering our full
      offering of data and voice communications products in a defined area.

  Customer Relationship Management Team

   In addition to supporting our Customer Acquisition Team, the Customer
Relationship Management Team is responsible for managing ongoing relationships
with our customers. This team includes the following professionals:

  .   Integrated Systems Manager. Our Integrated Systems Managers supply
      technical expertise and support our sales analysts in complex data and
      voice communications product sales. They are also instrumental in the
      configuration and installation of customer premise equipment.

  .   Business Development Manager. Our Business Development Managers seek to
      increase our potential revenue per customer by identifying the
      customer's evolving communications requirements and delivering a
      broader spectrum of our communication solutions to suit their needs, as
      well as roll out new products as they become available.

  .   Branch Administrator. Our Branch Administrators are responsible for
      maintaining and auditing quality order standards and implementing and
      ensuring policies and best practices are implemented within each
      office.

   To attract and motivate sales executives, we provide a comprehensive
compensation package that includes a base salary, stock options and an
attractive commission plan for achieving certain levels of performance.
Commissions and bonuses are based on specific quotas for services, emphasizing
the sale of integrated services. We believe that our commitment to recruiting,
training, activity management and equity participation will be critical to
achieve our direct sales objectives.

  Training

   We have developed a 10-week training program, NETtel University, for new
direct sales employees. The program includes classroom-oriented training that
covers our culture and mission, the fundamentals of the data and voice
communications industry, our product and service offerings and selling and
activity management skills. This classroom experience will be augmented with
field training where new recruits will observe seasoned sales representatives
and develop potential customers. In addition, we have designed and implemented
an advanced sales training program, an on-line training course for direct

                                       48
<PAGE>

sales offices and technical training covering advanced data applications,
dedicated T-1 and DSL services. We believe our training program will provide
our direct sales force with the skills necessary to execute a consultative
sales approach and product knowledge critical to delivering a complete solution
for the complex telecommunications needs of medium-sized businesses.

  Branchise Sales

   A Branchise is a cooperative relationship between our company and an
independent, experienced telecommunications sales professional, who we
typically recruit in secondary markets to complement our direct sales force.
Branchises build a sales team exclusively to sell our services in exchange for
sales commissions, operational support and advance payments. Branchises use
pre-existing relationships, community sale canvassing and cold calls to sell
our services. We believe that the Branchise program enables us to reach
customers cost-effectively in regions that may not justify a direct sales
office. Each Branchise location typically has three to five sales people in
each office. We currently have 11 Branchise locations serving eight markets,
and we expect to have up to nine additional Branchises by the end of 2000.

   Our current Branchise locations include:

  .   Chicago, IL (2)

  .   Denver, CO

  .   Des Moines, IA (2)

  .   Long Island, NY

  .   Phoenix, AZ (2)

  .   San Diego, CA

  .   Syracuse, NY

  .   Tampa, FL

   Branchises are required to develop a three-year business plan, including
sales projections and capital requirements, and to have at least $50,000
available to invest in the Branchise. Branchises typically have three to five
sales professionals, who earn both new-business and residual commissions and
can participate in our equity compensation program. See "Certain Relationships
and Related Transactions -- Branchise Warrants." Branchises and their employees
typically participate in an initial training session conducted by one of our
regional Branchise managers, as well as in ongoing monthly training. Regional
managers monitor the ongoing performance of the Branchise and review monthly
sales results.

   Under the standard three-year Branchise agreement, we are committed to
advancing operational support payments to be netted against commission payments
for up to 12 months, provided that the Branchise achieves designated revenue
and employee targets. In addition, our Branchise agreements prohibit Branchises
from soliciting our Branchise-

                                       49
<PAGE>

procured customers on behalf of any other communications carrier, and from
changing, altering or tampering with such customers during the term of the
agreement and for two years thereafter.

   Our Branchise team has successfully implemented this Branchise program at
two previous telecommunications carriers, Allnet and Frontier. The senior
management team has worked together for the past seven years and has
successfully recruited former successful Branchises to open Branchise offices
for us.

  Independent Agents

   We also market our services through an independent agent program. We hire
agent sales managers, or ASMs, with an average five years' experience as
successful sales people to manage our agents. ASMs are located throughout the
country and are responsible for recruiting and training independent agents.
Independent agents primarily utilize pre-existing relationships or referrals
for sales. New recruits generally have at least three to five years of
experience in marketing communications services. Many of these independent
agents have longstanding relationships with businesses in particular geographic
markets and employ sub-agents with similar customer relationships. We have
trained these agents who have previously only sold a long distance product to
sell dedicated Internet and voice products, which have dramatically improved
their positioning with their longstanding customers.

   As of March 31, 2000, we had eight ASMs in eight cities, as follows:

  .   Atlanta, GA

  .   Dallas, TX

  .   Denver, CO

  .   New York, NY

  .   Oakland, CA

  .   Orlando, FL

  .   Panama City, FL

  .   Washington, DC

In addition, as of March 31, 2000, we had non-exclusive agreements with 25
active independent agents. Each agent manager is responsible for recruiting and
managing up to 10 independent agents in eight cities. We plan to employ a total
of 15 ASMs managing up to 150 agents by the end of 2000.

Customer Operations

   We have designed and staffed our customer operations team to manage all
stages of the customer relationship beginning when an order is submitted. The
team is responsible for quality order standards, provisioning, billing,
maintenance, repair and all other customer care issues. We believe a single
team managing the customer relationship enables us to provide one of the
highest levels of customer care in the industry.

                                       50
<PAGE>

Customer Care

   We use state-of-the-art technology and experienced employees to provide a
highly responsive and efficient customer care experience. Our integrated
operational support systems and Web-based customer care solution allow us to
provide our customers with up-to-date information regarding their order status,
billing history, management and usage reports and network performance.

  One Call Resolution

   We strive to provide a one call resolution capability to all of our
customers. Unlike traditional communications companies where customers
typically experience multiple handoffs across the organization, from service
delivery to customer care, to credit and collections, to billing support and to
repair, our customer care representatives, known as CCRs, are the single point
of contact for our customers. CCRs are accountable for resolving any customer
inquiry, including service delivery, credit issues, network repair or billing.
CCRs are located in the same facility as our provisioning, credit analysis and
billing support groups, giving them direct and immediate access to the
personnel with the expertise to solve the most common customer service issues
and quickly resolve any customer issue. In order to further streamline customer
care, we are implementing Clarify, a leading customer relationship management
system that is seamlessly integrated with an automated call distribution
platform. This system identifies the incoming customer call and matches it with
the complete customer record, which appears on the CCR's computer screen and
provides the CCR with access to all of the customer's current account
information.

   Our integrated customer care approach reduces provisioning time, improves
provisioning accuracy and enables us to solve customer issues expeditiously
while preventing duplicative calling. Our customer care department is designed
to be highly scalable to accommodate rapid expansion of our customer base and
revenue. We offer customer care 24 hours a day, seven days a week using a
combination of internal CCRs and third-party relationships.

   iCARE

   We launched our Web-based customer care solution, iCARE, in August 1999.
This service allows our customers to go on-line to report trouble tickets,
review their bill, pay their bill and generate numerous usage reports. In
addition, customers can research numerous product features and benefits and
request additional information. By year-end, we plan to offer our customers the
ability to obtain automated service activation capabilities and to modify the
services they receive through our Web site, www.NETtel.com.

Operations

   Provisioning

   We align the responsibilities of our provisioning department with our sales
channels by building dedicated activation teams for direct sales, Branchises
and independent agents.

                                       51
<PAGE>

Employees in our provisioning department are also motivated by incentives based
upon meeting our overall monthly revenue targets. As we continue to implement
our integrated operational support systems, we expect to automate all stages of
the provisioning process which will include real-time audit and reporting
capabilities.

   Billing Support

   Our billing support department is responsible for ensuring that customers
receive bills that accurately reflect both services and prices. This department
supports our CCRs and our credit collections department with complex research
requests and dispute analysis, and its overall performance is evaluated based
in part upon revenue assurance.

Operational Support Systems (OSS)

   We believe our integrated OSS, which is designed to support scalable,
sustainable and predictable business capabilities, will provide us a
significant competitive advantage by enabling us to offer superior customer
care and maximize our order through-put. To realize this objective, we have
hired a team of approximately 50 full-time engineering and information
technology professionals with significant experience in the data and
telecommunications industries.

   Architecture

   We have adopted a core architecture and systems integration approach in
order to provide rapid implementation and deployment of our operational support
systems. Our fully integrated "plug and play" architecture supports the
transportation of information between the core functional components of
operational support systems by means of a single integrated platform, known as
the back plane, linking all components. This architecture is more efficient
than legacy systems, which are generally less stable and more expensive and
complex to maintain, upgrade and integrate. We believe our operational support
systems approach facilitates the ability to provide an intimate customer portal
for customer service and customer self-service activities using our iCARE
application on our Web site.

                                       52
<PAGE>

   The figure below illustrates our strategic architectural approach,
indicating the functional areas that are integrated using the back plane.
Commercial off-the-shelf applications are initially identified for functional
abilities and architectural compatibilities; next, we implement the
applications, core capabilities or appropriate "out-of-the-box" functionality;
finally, we incrementally make application functionality available for use
based on requirements.

               [Operational Support System Diagram Appears Here]

   We believe that our integration strategy for our operational support systems
will provide significant competitive advantages in terms of efficiency,
capacity to process large order volumes and the ability to deliver exceptional
customer care. We are developing a seamless end-to-end system that will
synchronize multiple business processes. This system will allow information to
be entered once and at the appropriate time within our sales, customer care,
trouble management and billing process. Information will then be shared between
the various components of our systems. Our single entry process is less labor
intensive, reduces the margin for error and significantly decreases the sales
to billing interval.

  Overview of Applications

   All of our core applications are seamlessly integrated into a single system.
The following applications are components of our operational support systems:

  Systems Integration/Process Automation Back Plane

   We are currently in the process of integrating all of the previously listed
core applications utilizing Vitria software. This software, allows us to create
a "plug and play" component solution to systems integration, eliminating the
need to write customized programs to integrate our software applications.

  Sales Force Automation, Order Entry and Trouble Management

   We are integrating Clarify, Cygent and MetaSolv to provide an automated
order entry, trouble management and sales force automation package. Clarify
provides us the ability to have orders entered directly in the sales offices
and ensures that all orders are submitted accurately. Clarify interfaces with
MetaSolv and enables us to have flow-through order management from point-of-
sale to the billing system. In addition, our integration approach provides our
sales offices with real-time updates on the progress and status of orders and
trouble tickets so that the sales representatives can provide customers with
accurate and timely updates.

  Provisioning, Inventory and Order Management

   We have entered into an agreement with Metasolv Software, Inc. to license
its Telcom Business Solution software to manage our order entry, installation,
network design, inventory and process management and which interfaces with our
network providers. This software interfaces with our network providers and
allows our sales team to monitor the status of the order through service
implementation.

  Gateways and Electronic Bonding to the RBOCs

   We have licensed software from DSET that will give us the ability to
electronically exchange order information with RBOCs. While many communications
providers still initiate service for a customer by sending faxes or e-mails, or
in some cases, by remote data entry, our electronic bonding will directly feed
into the RBOCs' computer systems so that orders are processed on an automated
basis. By directly accessing the billing and service order records of the RBOC,
we are able to confirm in real time receipt and installation of service orders.

                                       54
<PAGE>

  iCARE, Customer Relationship and Self Service

   In August 1999, we introduced iCARE, our proprietary on-line customer care
portal, that enables customers to view and pay their bills, as well as obtain
numerous usage and management reports, over our secure Web site. In addition,
customers can trouble-shoot minor service issues or receive information about
additional product features and benefits. We continually add new
functionalities to iCARE and plan to offer our customers the ability to modify
their service directly over our Web site, which will be automatically
provisioned to our switch. The iCARE environment is currently being
transitioned to the Cygent framework, which will allow us to create a one-to-
one customer integration.

  Billing, Mediation and Fraud Prevention

   We have entered into an agreement with Saville Systems to utilize its
Saville Express Software. We will continue to use the EDS IX-plus platform
until we transition to Saville. Saville's product enables us to combine and
bill current and future service offerings and present the information on a
single bill for our customers. This system supports customer care functions,
including billing inquiries and collection processes. Call detail records, such
as the billing records generated by our data or voice switches, will be
automatically processed in order to calculate and produce bills in a variety of
formats. Customers will be able to choose specific management reports and
access their account information over our Web site. The functionality of the
application allows rapid and flexible changes to product pricing, rating and
provisioning without significant provisioning time. In addition, our mediation
and fraud solutions will enable us to monitor abnormal usage patterns and
respond accordingly.

  Financial Systems and Decision Support

   In January 2000, we launched our enterprise accounting system, the Lawson
INSIGHT Business Management System. We implemented the general ledger and
procurement modules and are currently implementing the project management and
human resources modules. Lawson will receive information feeds from our billing
system (Saville), our provisioning system (MetaSolv) and our electronic bonding
system (DSET), which will enable us to more efficiently compile financial
information from all of the functional areas of the company. In addition, we
built datamarts using Essbase, which enable us to create numerous key
performance indicators, as well as enhance reporting of revenue and facilities
costs using Brio and other decision support tools.

Network Design

   We employ a "smart build" strategy, installing integrated data and voice
switches, purchasing long haul fiber and leasing local fiber where we have, or
plan to have, a sales presence. Owning these portions of our network enables us
to enhance the quality of services and implement new technologies as they
become available and allows us to efficiently deploy additional transmission
capacity and switching equipment as we grow. As of March 31, 2000, we had
installed 10 switches and purchased approximately 9,000 OC-3 fiber miles from
Williams. We intend to install 11 additional switches during 2000.

                                       55
<PAGE>

At the end of our Phase I network deployment, we will have switches installed
in 21 cities, serving 26 markets where we have, or expect to have, a sales
force. In addition, through our strategic partnership with Williams, we have
access to facilities reaching an additional 14 markets in which we have
customers with traffic volume that does not yet justify installing a switch.
Our packet-switched network technology enables us to offer integrated broadband
data and voice services over a single connection to our customers. Many of our
competitors use separate networks to deliver data and voice services, which is
less efficient and more expensive. Our network operations department, which is
responsible for all aspects of our network, currently has over 85
professionals.

   We implement our smart build network strategy by installing our integrated
data and voice communications switch when we first enter a market so that we
can immediately offer an integrated solution to a customer. This strategy
requires a larger capital investment up-front; however, we believe that by
offering integrated services as quickly as possible in a market, we can capture
the majority of a customers' total communications budget, creating a
competitive advantage and building barriers to entry. This strategy enables us
to generate positive cash flow more rapidly than if we constructed our own
transmission facilities.

   Our network enables us to transmit data, local and long distance voice
traffic using packetized, ATM protocol over a single T-1 connection. Our IP/ATM
backbone allows us to:

  .   provide our customers with a cost-effective package of integrated
      product features and services;

  .   realize enhanced gross margins through ATM compression and circuit
      optimization; and

  .   reduce customer churn.

   We intend to minimize technology risk by purchasing network equipment on a
turnkey basis from Nortel and Tellabs. Our ATM-based network includes:

  .   SuperNodes, each consisting of a Nortel DMS-500 local and long
      distance voice switch, a Tellabs DACS, which enables us to separate
      the data and voice communications traffic once it reaches our central
      office, a Cisco 7507 IP high-speed router and a Nortel Passport 8780
      series ATM switch;

  .   CityNodes, each consisting of a Tellabs DACS, Cisco 7507 IP router, an
      8780 ATM Passport switch and associated equipment, serving as regional
      points-of-presence, or POPs, to enable us to aggregate our Internet
      and voice traffic;

  .   9,000 OC-3 fiber miles connecting our switch sites; and

  .   leased DS3s connecting our central offices.

   We expect the ATM protocol to provide us with significant economic and
operational advantages as compared to many of our competitors. Our ATM network
permits significant bandwidth compression without a loss of voice quality by
continually assessing

                                       56
<PAGE>

network traffic volumes and applying bandwidth-saving compression algorithms.
We believe that such compression technology will permit us to transport more
traffic over leased DS3s than a traditional circuit switched interexchange
carrier. Our network employs SS7 signaling and utilizes least cost routing
algorithms to minimize costs. In addition to our least cost routing
applications, our network will dynamically assess and evaluate network traffic,
rerouting traffic in the event of outages or congestion. We expect our network
engineering to result in higher call completion ratios for our voice customers
and faster data transfer for our data customers.

   We currently are designing application hosting centers that will be built in
the same locations as our switches in our Dallas and Washington, DC facilities.
Our application hosting centers will enable us to offer on-net Web hosting and
application hosting services and also will allow us to provide collocation
services for strategic partners and large customers that wish to have a network
presence in our facilities. Our secure data centers will encompass 10,000 to
15,000 square feet and will include computer racks, fiber entrance facilities
and redundant sources of power.

   The diagram set forth below provides an overview of our ATM network design.

                       [ATM Network Diagram Appears Here]

  Network Management Center

   Our Network Management Center, or NMC, located at our SuperNode site in
Washington, DC, enables us to remotely monitor and maintain our nationwide
network 24 hours a day, seven days week. Our NMC provides secondary technical
support to the field operations force to troubleshoot and resolve all systems
and equipment issues in a rapid and transparent manner. It is also the single
point of contact for troubleshooting network issues with other carriers.

   The NMC utilizes a Network Management System from Harris Corporation. The
Harris Network Management System is a state-of-the-art integrated network
management

                                       57
<PAGE>

solution used by telecom carriers throughout the world. The system is UNIX and
Oracle based, which provides us with a highly reliable and scalable platform to
meet our network growth. It also contains integrated trouble resolution and
network performance tools to quickly detect, evaluate and respond to changing
network conditions. It monitors and controls all network elements within our
network.

   Our NMC system is fully integrated not only with the network elements, but
also with our other OSS systems. We maintain a redundant NMC server at a
different facility. Our NMC became operational in January 1999 and was moved
into its permanent location at our Washington, DC SuperNode site in March 2000.

Deployment

   We plan to deploy our network in two phases:

   Phase I

   Our Phase I network deployment is designed to overlay our nationwide sales
footprint. This strategy will enable us to quickly migrate existing customers
to our network while also providing the infrastructure necessary to provision
new customers directly on our network.

   The Company has deployed or expects to deploy Phase I SuperNodes and
CityNodes in the following markets:

   Phase II

   In our Phase II plan, we intend to deploy our network in markets that have
customer profiles that match our target customers, where we have a newly
established sales office

                                       58

or where we open a sales office in parallel with bringing a new switch in
service. We have plans to install our network in 12 additional markets
representing 12.1% of the total US non-residential access lines by the end of
2001. We will need to raise additional capital to finance our Phase II plan.

Competition

   The telecommunications industry is highly competitive, and one of the
primary purposes of the Telecommunications Act is to foster additional
competition. In each of our markets, we compete principally with the ILEC,
which is generally one of the RBOCs. The ILECs have long-standing relationships
with their customers, financial, technical and marketing resources
substantially greater than ours and the potential to fund competitive services
with cash flows from a variety of businesses. Furthermore, RBOCs may
increasingly be granted certain pricing flexibility and the ability to offer
data services without restrictions or obligations that apply to their voice
services. These possibilities may permit ILECs to use their captive customer
base to subsidize services that compete with ours.

   We also face competition from CLECs and other local competitors in our
markets. After the investment and expense of establishing a network and support
services in a given market, the marginal cost of carrying an additional call is
negligible. Accordingly, in those markets where there are facilities-based
CLECs, we expect substantial price competition.

   Other potential competitors in our markets also include resellers,
microwave, satellite and other wireless telecommunications providers and RBOCs
seeking to operate outside their current local service areas. The development
of networks utilizing new technologies, such as terrestrial wireless networks
and satellite transmission, which can be used to provide high capacity data,
LAN, Internet access and interactive services, might also create significant
new competitors that may have a lower cost basis than we have.

   Prices in both the long distance and data transmission businesses have
declined significantly in recent years and are expected to continue to decline.
In our long distance services, we will face competition from large carriers,
such as AT&T Corp., MCI WorldCom, Qwest and Sprint Corporation, as well as from
other resellers and companies

                                       59
<PAGE>

offering Internet telephony services. In addition, long distance carriers,
including AT&T, MCI WorldCom and Sprint, as well as smaller carriers, have
begun to offer integrated local and long distance telecommunications services.
The RBOCs also are making efforts to gain regulatory permission under the
Telecommunications Act to offer their own bundled local and long distance
services. Bell Atlantic-New York already has obtained such authority.

   We expect to experience declining prices and increasing price competition.
We cannot assure you that we will be able to achieve or maintain adequate
market share or margins, or compete effectively, in any of our markets.
Moreover, a substantial number of our current and potential competitors may
have financial, technical, marketing, personnel and other resources, including
brand name recognition substantially greater than ours, as well as other
competitive advantages over our business.

Employees

   As of March 31, 2000, we employed approximately 430 employees. In addition
to our full-time employees, we also employ part-time personnel from time to
time in various departments. None of our employees are covered by a collective
bargaining agreement. We believe that our employee relations are satisfactory.

Properties

   Our principal executive offices currently are located in Washington, DC;
however, we anticipate moving our corporate headquarters to McLean, VA in
August 2000. We have entered into a lease for over 113,000 square feet of
office space for our new corporate offices. In addition to our corporate
headquarters, we lease and sublease office space and switch sites in Addison,
TX; Anaheim, CA; Atlanta, GA; Chicago, IL; Houston, TX; Los Angeles, CA; New
York, NY; Orlando, FL; Peabody, MA; San Francisco, CA; San Ramon, CA;
Schaumburg, IL; Southfield, MI; Washington, DC; and Westbury, NY.

individually or in the aggregate, have a material adverse effect on our
financial condition or results of operations.

                               GOVERNMENT REGULATION

   The following summary of regulatory developments and legislation, while not
exhaustive, describes the primary present and proposed federal, state and local
regulation and legislation that is related to the Internet and
telecommunications industries and could have a material effect on our business.
Existing federal and state regulations are currently subject to judicial
proceedings, legislative hearings and administrative proposals that could
change, in varying degrees, the manner in which our industries operate. We
cannot predict the outcome of these proceedings or their impact upon the
Internet and telecommunications industries or upon us.

Overview

   Our telecommunications services are subject to federal, state and local
regulation. 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 interstate or international communications.
State regulatory commissions exercise jurisdiction over facilities and services
to the extent those facilities are used to provide, originate or terminate
intrastate communications. In addition, as a result of the passage of the
Telecommunications Act, state and federal regulators share responsibility for
implementing and enforcing the domestic pro-competitive policies of the
Telecommunications Act. In particular, state regulatory commissions have
substantial oversight over the provision of interconnection and non-
discriminatory network access to CLECs. Local governments often regulate the
public rights-of-way necessary to install and operate networks.

Federal Regulation

   The Local Competition Provisions of the Telecommunications Act

   The Telecommunications Act provides for comprehensive reform of the nation's
telecommunications laws. The Telecommunications Act is designed to enhance
competition in the local telecommunications marketplace by removing state and
local barriers to market entry by competitive telecommunications providers,
requiring ILECs to provide interconnection to their facilities, facilitating
the end user's choice to switch service providers from ILECs to CLECs and
requiring access to public rights-of-way.

   The Telecommunications Act specifically requires all local exchange carriers
(including ILECs and CLECs) not to prohibit or unduly restrict resale of their
services; to provide, to the extent technically feasible, the ability of
customers to retain their telephone number when they change telecommunications
providers; to provide nondiscriminatory access to telephone numbers and
directory listings; to afford access to poles, ducts, conduits and rights-of-
way; and to establish arrangements by which local telephone companies will
compensate each other for exchanging telecommunications traffic.

   ILECs have numerous additional obligations toward CLECs. ILECs are required
to negotiate and provide interconnection for the exchange of traffic at any
technically feasible point within the ILEC's network at rates, terms and
conditions that are just, reasonable

                                       62
<PAGE>

and nondiscriminatory. ILECs also are required to lease certain portions of
their networks and provide space in their switching offices so that requesting
telecommunications carriers can physically "collocate" equipment necessary for
interconnection or access to unbundled network elements. ILECs must provide
such services and arrangements at cost-based rates.

   In 1997, the U.S. Court of Appeals for the Eighth Circuit vacated portions
of the initial FCC local competition rules and, in particular, vacated on
jurisdictional grounds the FCC's interconnection and unbundled network elements
pricing rules as well as other rules adopted to implement Sections 251 and 252
of the Telecommunications Act. On January 25, 1999, the United States Supreme
Court issued an opinion confirming the FCC's authority to issue regulations
implementing the pricing and other provisions of the Telecommunications Act and
reinstating most of the FCC rules previously vacated by the Eighth Circuit.
Among other things, the Supreme Court held that the FCC has general authority
under the Telecommunications Act to promulgate regulations governing local
interconnection pricing, adopt a "pick and choose" rule, which enables CLECs to
adopt portions of existing interconnection agreements, and enact rules
governing access to unbundled network elements. However, the Supreme Court
vacated a key FCC rule identifying the network elements that ILECs are required
to unbundle and remanded this issue to the FCC for further consideration. On
November 5, 1999, the FCC, in response to the Supreme Court's remand, issued an
order revising its rules on the network elements that incumbents must make
available. The order adopts stricter requirements for when a network element
must be made available to CLECs by an ILEC and, using these standards,
concluded that operator services and directory assistance need not be
unbundled. The order also determined that switching functions need not be
unbundled in certain urban markets for service to larger customers. The FCC's
order has been appealed. In addition, the Eighth Circuit is now considering
certain issues left undecided by the Supreme Court's decision pertaining to
substantive challenges to the FCC's interconnection rules, including the
validity of the FCC's pricing methodology. These appeals create uncertainty,
which may have an adverse effect on our ability to negotiate interconnection
agreements with ILECs.

   RBOC Entry into Long Distance. The Telecommunications Act also established
procedures under which an RBOC can enter the market for long distance services
within the area where it provides local exchange service (the
Telecommunications Act permitted the RBOCs to enter the out-of-region long
distance market immediately upon enactment). Before an RBOC can originate in-
region long distance services, it must obtain FCC approval upon showing that it
has entered into interconnection agreements in the states where it seeks
authority, that the interconnection agreements satisfy a 14-point "checklist"
of competitive market opening requirements and that such entry is in the public
interest. The FCC recently determined that Bell Atlantic-New York has satisfied
these requirements. The provision of in-region long distance services by RBOCs
could permit them to offer "one-stop shopping" of bundled local and long
distance services, thereby eliminating our current marketing advantage, and
could reduce RBOC cooperation in our local markets. Several other RBOCs have
requests pending to provide interLATA services within their regions, and grants
of these or other requests could have an adverse effect on us.

                                       63
<PAGE>

   RBOC Data Services. In the spring of 1998, four of the RBOCs petitioned the
FCC to be relieved of specified regulatory requirements in connection with
their provision of high-speed data services, including obligations to unbundle
high-speed data loops and to resell such services. In October 1998, the FCC
ruled that high-speed data services are telecommunications services subject to
the unbundling and resale obligations of the Telecommunications Act. However,
the FCC has initiated a proceeding to determine whether RBOCs can create
separate affiliates for their high-speed data services that would be free from
these obligations. A decision in that proceeding permitting RBOCs to offer
these services through a separate subsidiary may have an adverse effect on us.

   Line Sharing. On November 18, 1999, the FCC adopted an order that directed
ILECs to share their local telephone lines so that competitors could make use
of the high frequency portion of the line. This will enable competitive
carriers to use DSL technology to provide high-speed data services over the
same telephone lines simultaneously used by ILECs to provide basic telephone
service, a technique referred to as "line sharing." The short term effect of
this order is difficult to predict, as the FCC left it to the states to
determine how line sharing should be implemented and what rates the ILECs may
charge. This process could take some time, even without factoring in the
appeals of this order that have been filed. In the long-term, however, this
rule could have the effect of sharply reducing prices for DSL service.

   Reciprocal Compensation for ISP-bound Traffic. We believe that, under the
Telecommunications Act, CLECs are entitled to compensation from ILECs for
delivering traffic bound for ISP customers of the CLECs. The Telecommunications
Act requires ILECs to compensate CLECs for delivering local traffic to ILEC
customers--based, in part, on the realization that such traffic imposes a cost
on the CLECs that must be reimbursed. Several ILECs have argued that traffic
bound for ISPs is not "local" traffic and therefore not subject to compensation
obligations. The ILECs' position was supported by an FCC ruling that local
traffic to ISPs is interstate, not local. In so finding, the FCC applied an
"end-to-end" analysis--because the communication would ultimately extend beyond
the ISP to Websites out-of-state and around the world, it is non-local in
nature. While the FCC declined to upset prior state commission rulings in this
regard, the FCC did indicate that states may reevaluate their prior decisions
in light of the FCC's ruling. Upon such reexamination, many state commissions
and courts, but not all, continued to require ILECs to pay reciprocal
compensation pursuant to pre-existing interconnection agreements. On March 24,
2000, the DC Circuit vacated the FCC's ruling regarding ISP traffic, holding
that the FCC failed to explain adequately why it applied an end-to-end
analysis, which was previously used solely in making jurisdictional
determinations, to determine whether reciprocal compensation was owed for ISP-
bound traffic. Despite this decision, there can be no assurance that any future
FCC decision on this matter on remand or otherwise will be in our favor. A
ruling that ISP-bound traffic is not subject to reciprocal compensation
obligations would have an adverse effect on us.

   Internet. Our Internet operations are not currently subject to direct
regulation by the FCC. However, the future ISP regulatory status continues to
be uncertain. In an April

                                       64
<PAGE>

1998 report, the FCC concluded that some services offered over the Internet,
such as phone-to-phone IP telephony, may be functionally indistinguishable from
traditional telecommunications service offerings and that their non-regulated
status may have to be re-examined. Moreover, although the FCC has decided not
to allow local telephone companies to impose per-minute access charges on ISPs,
further regulatory and legislative consideration of this issue is likely. The
imposition of access charges would affect our costs of serving dial-up
customers and could have a material adverse effect on our business, financial
condition and results of operations. In addition, increased regulation of the
Internet as a result of state or federal initiatives, including regulating or
criminalizing certain content, may slow its growth and reduce potential
revenue, particularly if other governments follow suit. ISPs also are subject
to intellectual property laws and export laws and have obligations to protect
the privacy of certain information provided to them by Internet users. These
regulations and obligations may increase the cost of complying with new laws or
doing business over the Internet, may reduce our profits and generally
adversely affect our business, financial condition, results of operations and
future prospects.

   Tariffs. Services of nondominant carriers have been subject to relatively
limited regulation by the FCC, primarily in the form of rate schedules and
terms of service ("tariffs") and making periodic compliance reports. However,
in October 1996, the FCC adopted the Detariffing Order, which eliminated the
requirement that nondominant interstate carriers maintain tariffs on file with
the FCC for domestic interstate services and provided that, after a nine-month
transition period, relationships between interstate carriers and their
customers would be set by contract, not tariff. These rules were stayed by the
DC Circuit. If the FCC's order becomes effective, nondominant interstate
service providers will no longer be able to rely on the filing of tariffs with
the FCC as a means of providing uniform notice to customers of prices, terms
and conditions under which they offer their interstate services. Rather, we
will need to implement replacement contracts with each customer, which could
result in substantial administrative and marketing expenses. The FCC, however,
has indicated that it may choose instead to implement a permissive tariffing
policy allowing carriers to determine individually whether to file tariffs with
the FCC. Adoption of a permissive tariffing policy would alleviate the
substantial administrative and marketing expenses that could arise if the
Commission eliminated tariffs altogether.

   The Telecommunications Act requires the FCC to streamline its regulation of
carriers, including ILECs, and permits the FCC to forbear from regulating
particular classes of telecommunications services or providers. In June 1997,
the FCC granted the request of a CLEC that the FCC forbear from imposing tariff
filing requirements on exchange access service provided by carriers other than
ILECs. The FCC has sought further comment on whether to mandate the detariffing
of exchange access services. The proceedings remain pending and there can be no
assurance of how the FCC will rule on this issue or what effect any such ruling
may have on competition within the telecommunications industry generally, or on
our competitive position specifically.

                                       65
<PAGE>

   International Services. As a nondominant carrier, we are required to obtain
FCC authorization pursuant to Section 214 of the Communications Act and file
tariffs before providing international communications services. We also are
subject to certain reporting requirements pertaining to our provision of
international services. In August 1997, the FCC adopted rules for a multi-year
transition to lower international settlements payments by U.S. common carriers.
We believe that these rules will likely lead to lower rates for some
international services and increased demand for these services, including
capacity on U.S. facilities, like ours, that provide these services.

   ILEC Price Cap Regulation Reform. The FCC has adopted a number of proposals,
which currently are under review before the DC Circuit, to significantly reduce
its regulation of ILEC pricing. These proposals would greatly enhance the
ability of ILECs to compete against us, particularly by targeting price cuts to
particular customers, which could have a material adverse effect on our ability
to compete based on price.

   Access Charges. The FCC has made and is continuing to consider various
reforms to the existing rate structure for charges assessed on long distance
carriers for connection to local networks. These reforms are designed to move
these "access charges," over time, to lower, cost-based rate levels and
structures. These changes will reduce access charges and will shift charges,
which historically had been based on minutes-of-use, to flat-rate, monthly per
line charges on end-user customers rather than long distance carriers. As a
result, the aggregate amount of access charges paid by long distance carriers
to access providers like us may decrease.

   At the same time, the FCC, noting the proliferation of fixed monthly charges
on the bills of long distance customers, recently initiated a public inquiry on
the impact of these charges on consumers who make few interstate long distance
calls but pay fixed end-user charges nonetheless. All of these initiatives
could reduce our revenue from access charges and diminish them as a source of
profits.

   In October 1998, AT&T sought a declaration from the FCC that AT&T may avoid
CLEC access charges by declining to direct calls to the customers of those
CLECs. While the FCC denied this request, it indicated that it intended to
initiate a proceeding to examine CLEC access rates. In addition, AT&T and
Sprint have sent letters to virtually every CLEC demanding a reduction in
access charges to a "competitive" level or risk service interruption and, in
many instances, have refused to pay the tariffed rate for access services, if
at all. A decision by the FCC allowing long distance companies to refuse to
purchase competitive providers' switched access services may adversely affect
competitive local carriers such as us.

   Universal Service Reform. On May 8, 1997, the FCC issued an order to
implement the provisions of the Telecommunications Act relating to the
preservation and advancement of "universal telephone service," a long-standing
policy designed to ensure that as many people as possible have access to basic
telephone service at affordable rates, particularly in rural and high-cost
areas, as well as providing advanced telecommunications services for schools,
rural health care providers and libraries. All telecommunications carriers
providing interstate telecommunications services, including us, must contribute
to

                                       66
<PAGE>

the universal service support fund based on end-user telecommunications
revenue. Contribution factors vary quarterly, and carriers, including us, are
billed monthly. In November 1999, the FCC issued an order revising its rules
for calculating the size of the universal service fund. Further, FCC rule
changes, as well as obligations to contribute to similar state programs, are
likely to increase the overall cost to telecommunications carriers.

   Consumer-Oriented Regulation. There are various consumer-oriented rules
which, if violated, could result in substantial fines and harm to the company's
business reputation. For example, carriers may be subject to significant fines
by the FCC and state commissions for the fraudulent or unauthorized switching
of an end user's primary carrier, a practice known as "slamming." Even one
slamming complaint could cause extensive litigation expenses for us. Although
currently not as prevalent as slamming, competitive providers also may be
subject to substantial fines or litigation for "cramming," a practice in which
customers are billed for services they did not order or authorize, as well as
for violation of state consumer protection rules, such as telemarketing to
consumers on "do not call" lists. The FCC also has adopted rules governing the
use of customer proprietary network information and regulating the form and
content of consumer bills. These regulations require the development of
internal policies and revised practices which may increase our costs of
providing telecommunications services.

State Regulation

   Nearly all states in which we propose to operate require a registration,
certification or other authorization to offer intrastate telecommunications
services. In most states, we also are required to file tariffs setting forth
the terms, conditions and prices for services that are classified as
intrastate. Some states also impose reporting, customer service and quality
requirements, as well as universal service and other contribution requirements.
In addition, we will be subject to the outcome of generic proceedings held by
state utility commissions to determine new state regulatory policies. Some
states, including some of our target states, have adopted or have pending
proceedings to adopt specific universal service funding obligations. These
state proceedings may result in obligations that are equal to or more
burdensome than the federal universal service obligations.

   In addition to obtaining certification and complying with other state
regulatory requirements, we must negotiate terms of interconnection with the
ILEC in each state in which we operate. To date, we have negotiated
interconnection agreements with one or more of the ILECS in certain states in
which we have been certified. State commissions preside over arbitrations of
agreements. Agreements are in any case subject to state commission approval.

   We are also subject to requirements in some states to obtain prior approval
for, or notify the state commission of, any transfers of control, sales of
assets, corporate reorganizations, issuance of stock or debt instruments, name
changes and other transactions that may effect a change in the way that we do
business. Although typically such authorizations can be obtained in the
ordinary course, there can be no assurance that the state commissions would
grant us the authority to complete any such transaction should we request such
authorization.

Local Authorizations

   If we elect to construct a fiber optic network, we may be required to obtain
municipal franchises and other permits. These rights are typically the subject
of non-exclusive agreements of finite duration and provide for the payment of
fees or the provision of services to the municipality. In addition, we must
secure rights-of-way, pole attachments and other access rights, which typically
are provided under non-exclusive multi-year agreements that generally contain
renewal options. In some municipalities, we will 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.

Fiscal Year End Option Values

   The following table sets forth certain information regarding unexercised
options held by our Chief Executive Officer and each of our four other most
highly compensated executive officers, whose total cash and cash equivalent
compensation exceeded $100,000 for the fiscal year ended December 31, 1999. The
calculations of the value of unexercised options are based on the difference
between the initial public offering price of $    per share, and the exercise
price of each option, multiplied by the number of shares covered by the option.

Employment Agreements; Covenants-not-to-Compete

   James F. Kenefick. In April 2000, we entered into an employment agreement
with Mr. Kenefick to be our Chief Executive Officer and President. The
employment agreement ends on March 31, 2003, unless it is terminated earlier
under the terms of the agreement. When the initial term ends, the agreement
automatically renews for additional one-year periods unless the agreement is
terminated with 90 days' written notice. The annual base salary under Mr.
Kenefick's agreement is $300,000 for the first year, $325,000 for the second
year and $350,000 for the third year. In addition to his base salary, Mr.
Kenefick is entitled to quarterly and annual incentive compensation based on
the Company's satisfaction of the Financial Plan approved by our board of
directors, which includes quarterly revenue and EBITDA targets.

   If we terminate Mr. Kenefick's employment without cause or if Mr. Kenefick
terminates his employment for good reason, then Mr. Kenefick is entitled to two
years' severance pay plus pro rata incentive compensation benefits and payment
for unused personal days. If Mr. Kenefick terminates his employment for a
reason other than good reason, he is entitled to six months' severance pay. We
may terminate Mr. Kenefick's employment at any time for cause, and he would not
be entitled to any severance payment.

   In connection with his employment agreement, Mr. Kenefick also will receive
options to purchase 750,000 shares of common stock. The exercise price of one-
third of these options will be equal to the price per share of our common stock
at the closing of this offering, the exercise price of one-third will be 150.0%
of the offering price, and the exercise price of one third will be 200.0% of
the offering price.

   Other Key Executive Employment Agreements. We have also entered into
employment agreements with Messrs. Allen, Bandes, Langston, Lynch, McNamara and
Rehberger. Each employment agreement lasts until it is terminated under the
terms of the agreement

                                       75
<PAGE>

by either the executive employee or us. Mr. Allen's annual salary is $162,000,
Mr. Langston's annual salary is $165,000 and Mr. Rehberger's annual salary is
$225,000. The annual salary for Messrs. Bandes, Lynch and McNamara is $180,000.
Each of these executive employees may receive cash bonuses based on certain
performance goals.

   If we terminate any of these executives without cause, then the terminated
executive is entitled to up to one year's severance pay (depending upon the
terms of his employment agreement) plus any commissions earned up to the date
of termination, if applicable, and payment for unused personal days.

   In each employment agreement, the employee agreed to preserve during and
after his employment the confidential and proprietary nature of all information
relating to us and our business, and he also agreed that he would not compete
with us during his employment and for up to one year thereafter, for which he
would receive severance pay of one year's salary. In addition, each of these
executive employees agreed that he would not solicit our employees or current
or potential customers during his employment and one year thereafter.

1998 Stock Incentive Plan

   On January 26, 1998, our board of directors and stockholders approved our
1998 Stock Incentive Plan, which allows us to directly award or sell shares of
our common stock and to grant options to purchase our common stock to our
employees, consultants and outside directors. Our incentive plan allows us to
issue both "incentive stock options" under the Internal Revenue Code and
options that are non-qualified for federal income tax purposes. On January 26,
1998, September 30, 1998, March 15, 1999, November 10, 1999 and January 25,
2000, the board adopted amendments to the plan increasing the number of shares
of common stock available for issuance under the plan, each of which was
approved by our stockholders. The purpose of our stock incentive plan is to
enhance our ability to attract, retain and compensate highly qualified
employees and other individuals providing us with services.

   The number of shares available for issuance under our incentive plan is
4,255,000 at March 31, 2000, subject to adjustment for stock dividends, splits
and other similar events. As of December 31, 1999, options to purchase
2,461,150 shares of common stock were outstanding under our stock incentive
plan. We have not directly awarded or sold any shares under our stock incentive
plan.

   Our stock incentive plan is administered by our Compensation Committee. The
Compensation Committee will determine, among other things, which officers,
employees and directors will receive options under the plan, the time when
options will be granted, the type of option (incentive stock option,
nonqualified stock options or both) to be granted, the number of shares subject
to each option, the time or times when the options will become exercisable and
the option price and duration.

NETtel Long-Term Incentive Plan

   Prior to the closing of the offering, our board of directors expects to
approve our proposed NETtel Long-Term Incentive Plan, and we will present it
for the approval of our stockholders at our 2000 annual meeting. The purpose of
our Long-Term Incentive Plan is

                                       76
<PAGE>

to enhance our ability to attract, retain and compensate highly qualified
employees and other individuals providing us with services. The number of
additional shares available for issuance under our proposed Long-Term Incentive
Plan will be 1,120,562 shares, subject to adjustment for stock dividends,
splits and other similar events. The shares available under the 1998 Stock
Incentive Plan and the proposed NETtel Long-Term Incentive Plan represent 15%
of our outstanding stock and will be maintained at that level as more stock is
issued. Under the proposed plan, we could grant stock appreciation rights,
restricted stock and options to purchase our common stock to our employees,
consultants (including certain vendors), officers and directors. Our proposed
Long-Term Incentive Plan would allow us to issue both "incentive stock options"
under the Internal Revenue Code and options that are non-qualified for federal
income tax purposes. In addition, under our proposed Long-Term Incentive Plan,
we may also grant common stock as a bonus or in lieu of payment of an
obligation, and we may grant other stock-based awards. The terms of our
proposed Long-Term Incentive Plan set forth a three year vesting schedule for
stock options and stock appreciation rights; however, the options and stock
appreciation rights become fully vested upon a change of control.

   Our Compensation Committee would administer our proposed Long-Term Incentive
Plan. The Compensation Committee would determine, among other things, which
employees, consultants (including certain vendors), officers and directors will
receive awards under the proposed Long-Term Incentive Plan, when awards will be
granted, the number of shares subject to each award, the type of option
(incentive stock option, nonqualified stock options or both) to be granted, the
time and conditions of any options granted, the form of payment for the award
and the option price and duration.

Employee Stock Purchase Plan

   Our employee stock purchase plan, which became effective on June 1, 1999,
provides for the issuance of up to 500,000 shares of common stock. This plan
provides our employees with an opportunity to purchase shares of common stock
through payroll deductions. Our purchase plan is implemented through a series
of offering periods of one year's duration, with new enrollment dates beginning
on January 1, April 1, July 1 and October 1 of each year. Shares are purchased
at the end of each offering period. The purchase price for each share purchased
in the offering period is the lower of 85% of the fair market value on the last
day in that offering period or 85% of the fair market value of the share on the
first day in that offering period.

   All of our employees who have been employed by us for more than three months
and who work for more than five months per calendar year and for more than 20
hours per week are eligible to participate in our purchase plan. Employees may
terminate their participation in our purchase plan or change their level of
participation in the plan at any time during the offering period. Participation
in our purchase plan terminates automatically on the participant's termination
of employment with us. Our purchase plan is administered by the Compensation
Committee of our board of directors.

401(k) Plan

   We maintain a tax-qualified employee savings and retirement plan covering
all of our employees. Under this 401(k) plan, employees may elect to reduce
their current compensation by a maximum pre-tax amount equal to the lesser of
15% of eligible compensation or the statutorily prescribed annual limit, which
was $10,500 in 1999, and have the amount of this reduction contributed to the
401(k) plan. The trustee under the 401(k) plan, at the direction of each
participant, invests the assets of the 401(k) plan in various investment funds.
The 401(k) plan is intended to qualify under Section 401 of the Internal
Revenue Code so that contributions by employees to the 401(k) plan, and income
earned on plan contributions, are not taxable to employees until withdrawn, and
so that the contributions by employees will be deductible by us when made.
Employees are immediately 100% vested in their individual contributions. The
401(k) plan provides for hardship withdrawals and employee loans.

Directors and Officers Insurance

   Prior to the closing of this offering, we intend to obtain directors and
officers liability and company reimbursement insurance. The policy will insure
against any liability asserted, against or incurred by, our directors and
officers arising out of their fulfillment of their responsibilities as such
director or officer, and related expenses, whether or not we would have the
power to indemnify them under the provisions of the Delaware General
Corporation Law.

                             PRINCIPAL STOCKHOLDERS

   The following table sets forth certain information as of March 31, 2000,
about the beneficial ownership of our capital stock, after giving effect to
this offering, by:

  .   each person who we know beneficially owns 5% or more of any class of
      our capital stock;
  .   each of our directors;
  .   each of our five named executives; and
  .   all of our directors and executive officers as a group.

   Unless otherwise indicated, the address for each stockholder listed is c/o
NETtel Communications, Inc., 1023 31st Street, N.W., Washington, DC 20007.
Except as otherwise noted, each of the persons in this table has sole voting
and investment power with respect to all the shares listed.

   Under the SEC's rules, a person is deemed to be the beneficial owner of a
security if that person has or shares the power to vote or direct the voting of
such security or the power to dispose or direct the disposition of such
security. A person is also deemed to be a beneficial owner of a security if
that person has the right to acquire beneficial ownership within 60 days.

   This table includes shares issuable upon the conversion of the outstanding
shares of preferred stock, the offering and shares which may be acquired upon
the exercise of options and equity warrants. On April 20, 2000, we completed a
private placement where we issued $12 million of our Series C Convertible
Preferred Stock. The shares of Series C Preferred Stock will automatically
convert into shares of our common stock upon the closing of this offering. The
table set forth below does not include the shares of common stock into which
the Series C Preferred Stock is being converted.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

$50 Million Series B Preferred Stock Private Placement

   On July 23, 1999, we closed a private placement of our Series B Convertible
Preferred Stock. In this private placement, we issued 2,587 shares of Series B
Preferred Stock to Nortel for approximately $20 million and 1,940 to Gold &
Appel Transfer, S.A. in exchange for approximately $7 million in cash and the
conversion of $8 million in debt from two short-term credit facilities. Under
the same private placement, on August 2, 1999, we issued 647 shares of Series B
Preferred Stock to Allied for approximately $5 million. At the same time, we
issued a warrant to Allied for the purchase of 474,160 shares of common stock
for a total purchase price of $100 as consideration for Allied's $10 million
loan to us under the Credit Agreement. Allied's warrant is fully vested and
immediately exercisable. For more information on our relationship with Nortel
and Allied, please see "Credit Agreement" in this section.

   Also in connection with the Series B private placement, Williams converted
its shares of Series A Preferred Stock with a face value of $10 million into
1,294 shares of Series B Preferred Stock with the same face value. Williams'
Series A Preferred Stock was issued in exchange for $5 million cash and $5
million in network credits under our Capacity Purchase Agreement. Please see
"Relationship with Williams Communications, Inc." in this section for more
information on our Capacity Purchase Agreement with Williams.

Series C Preferred Stock Private Placement

   On April 20, 2000, we closed a private placement of our Series C Preferred
Stock. In this private placement, we issued 567,537 shares of Series C
Preferred Stock to Nortel for approximately $5.0 million, 90,806 shares to Gold
& Appel in exchange for approximately $800,000, 340,523 shares to Allied for
approximately $3.0 million, 136,209 shares to the Foundation for the
International Non-Governmental Development of Space for $1.2 million and
227,015 shares to Williams for approximately $2.0 million in the form of a
credit against current year payments under our Capacity Purchase Agreement. The
Series C Preferred Stock is entitled to cash dividends of 8.0% per annum, which
may be paid in the form of additional shares of Series C Preferred Stock at our
option. Upon the closing of this offering, half of any accrued and unpaid
dividends converts into shares of common stock, and the remaining dividends are
payable, at our option, in either cash or shares of common stock.

Credit Agreement

   On July 28, 1999, we entered into a Credit Agreement with Nortel and Allied,
two of our holders of Series B Preferred Stock, for a total amount of $140
million. The agreement consists of a Term Loan A Facility in the amount of $120
million, a Term Loan B Facility in the amount of $10 million and a Revolving
Loan Facility with $10 million available. The Term Loan A Facility is

  .   to pay vendors of hardware, software and equipment (including Nortel)
      for the construction of our network;

                                       81
<PAGE>

  .   to pay acquisition costs (excluding lease costs) relating to our
      network sites; and

  .   for working capital and general corporate purposes.

   The Term Loan B Facility and the Revolving Loan Facility are to finance our
working capital needs and for general corporate purposes. Our indebtedness
under the Credit Agreement is secured by a first priority perfected security
interest in all of our present and future assets. If the loan under the
facilities is a Base Rate Loan, interest on the facilities is the highest
commercial prime or base rate plus 3.5% or the Federal Funds rate plus 4%. If
the loan is a Eurodollar Loan, the interest rate is the London Interbank
Offered Rate for deposits in dollars divided by one minus the maximum rate at
which reserves are required to be maintained during the interest period by the
Federal Reserve. Repayment of accrued interest is due for Base Rate Loans on
each monthly date and for each Eurodollar Loan on the last day of interest
period. As of December 31, 1999, borrowings under the Credit Agreement bore
interest at rates ranging from 10.15% to 10.68%.

   We must pay the Term Loan A Facility in 20 installments beginning on the
amortization commencement date. We must pay the Term Loan B Facility on the
maturity date. We are required to pay the Revolving Loan Facility in 20
installments beginning on July 30, 2001 or July 30, 2000 if Nortel has advanced
less than $35 million under the facility. We have certain mandatory prepayment
obligations under the facilities. The Credit Agreement requires us to meet
certain financial measures in addition to other non-financial covenants.

   At December 31, 1999, we had purchased approximately $12.0 million of Nortel
products and services which were financed under the Credit Agreement. At
December 31, 1999, we had approximately $18.1 million outstanding under the
Term Loan A Facility and approximately $3.6 million outstanding under the
Revolving Loan Facility. We paid approximately $315,000 in interest under the
Credit Agreement through December 31, 1999.

$35 Million Loan Agreement with Gold & Appel

   On April 13, 2000, we entered into a $35 million loan agreement with Gold &
Appel Transfer, S.A. We may borrow funds under the loan agreement at any time
from July 5, 2000 until the earlier to occur of July 5, 2001 or the closing of
this offering. Amounts outstanding under the loan bear interest at a rate of
12% per annum. Amounts outstanding under the loan agreement may be converted at
the election of holders of at least 75% of our Series B Preferred Stock into
common stock at a price per share which is equal to the conversion price per
share of any convertible preferred stock (or the price per share of any common
stock) we issue between April 13, 2000 and the closing of this offering.
Amounts outstanding under the loan agreement may be repaid at any time, and
must be repaid upon the earlier of July 5, 2001 or the closing of this
offering.

Relationship with Williams Communications, Inc.

   Our telecommunications network includes long distance fiber optic capacity
between our switching equipment. Certain of this fiber optic capacity is
provided and maintained by Williams. On June 28, 1999, we became parties with
Williams to a Capacity Purchase

                                       82
<PAGE>

Agreement. Under the agreement, we committed to purchase fiber optic capacity
or other services from Williams having a net present value at June 28, 1999 of
approximately $25 million over the term of the agreement. Concurrently with the
Capacity Purchase Agreement, we also entered into a Securities Purchase
Agreement with Williams, under which Williams purchased shares of our Series A
Preferred Stock with a stated value of $10 million in exchange for $5 million
in cash and $5 million in network credits. The shares of Series A Preferred
Stock were converted into shares of Series B Preferred Stock with a stated
value of $10 million on July 28, 1999, in connection with the Series B
Financing.

   We have applied the $5 million in network credits to our payment obligation
under the Capacity Purchase Agreement, and we are obligated to pay the balance
of approximately $20 million in equal monthly installments through June 2006.
Services which are subject to these payment terms are limited to $3 million per
fiscal year, and we are required to pay cash for any services over that amount.
During the fiscal year ended December 31, 1999, we purchased fiber optic
capacity and other services with a value of approximately $24.8 million from
Williams under the agreement.

Relationship with Epoch Networks, Inc.

   James Kenefick and Walter Anderson currently serve as directors of Epoch.
Mr. Kenefick and Gold & Appel are also stockholders of Epoch. In April 1998, we
entered into a four-year Branded Services Agreement with Epoch, or the Epoch
Agreement. Under the Epoch Agreement, we are an authorized Epoch Branded
Provider with respect to a variety of Internet access and related services
provided by Epoch and resold by us under the NETtel brand name. The Epoch
Agreement also requires us to meet a specified monthly minimum revenue
commitment or pay the shortfall. In 1999, we paid Epoch approximately $1.8
million under the Epoch Agreement. In the event that the Epoch Agreement is
terminated prior to the expiration of its term, we cannot assure you that we
will be able to obtain similar services from another ISP upon terms as
favorable as the terms provided under the Epoch Agreement.

Branchise Warrants

   Our agreements with our Branchises provide for annual awards of warrants to
purchase common stock. The warrants are issuable upon achievement of invoiced
revenue targets, vest over four years, are exercisable at fair market value as
of the award date and have a term of five years starting at the award date.
Awards under these agreements are limited to an aggregate of 1% of our fully
diluted common stock at any award date. See "Description of Capital Stock." At
December 31, 1999, warrants for 49,409 shares of common stock were issuable to
certain Branchises at an exercise price of $9.49 per share.

                          DESCRIPTION OF CAPITAL STOCK

   The following is a summary of the terms of our capital stock and does not
purport to be complete. For more information, please review our second amended
and restated certificate of incorporation.

General

   Our authorized capital stock currently consists of 200,000,000 shares of
common stock, par value $0.0001 per share, and 50,000,000 shares of preferred
stock, par value $0.0001 per share, of which no shares are designated as Series
A Preferred Stock, 11,200 are designated as Series B Preferred Stock and
11,350,738 are designated as Series C Preferred Stock. As of December 31, 1999,
there were 16,985,573 shares of common stock issued and outstanding, and
6,468.304 shares of Series B Preferred Stock issued and outstanding. We issued
1,362,090 shares of Series C Preferred Stock on April 20, 2000.

Common Stock

   Holders of common stock are entitled to one vote per share on all matters to
be voted upon by the stockholders; however, when stockholders elect the board
of directors, each common stockholder has cumulative voting rights and may cast
all of his or her votes for one director. Common stockholders are entitled to
receive dividends our board of directors may declare in its discretion out of
funds that are legally available for dividends, but the right of common
stockholders to receive dividends is limited by terms of our credit agreement
with Nortel, our Series B Preferred Stock and our Series C Preferred Stock. In
the event of our liquidation, dissolution or winding up, the holders of shares
of common stock are entitled to a distribution of any of our remaining assets,
subject to the terms of the preferred stock. The common stockholders have no
preemptive rights. All outstanding shares of common stock are fully paid and
nonassessable.

Preferred Stock

   The preferred stock may be issued from time to time by our board of
directors as shares of one or more series or classes. Subject to the provisions
of our amended and restated certificate of incorporation and limitations
prescribed by law, the board is authorized to issue the shares, fix the number
of shares, change the number of shares constituting a series and provide for or
change the voting powers, designations, preferences and relative,
participating, optional or other special rights, qualifications, limitations or
restrictions thereof, including dividend rights (including whether dividends
are cumulative), dividend rates, terms of redemption (including sinking fund
provisions), redemption prices, conversion rights and liquidation preferences
of the shares constituting any class or series of the preferred stock, in each
case without any further action or vote by the stockholders.

   One of the effects of undesignated preferred stock may be to enable the
board to render more difficult or to discourage an attempt to obtain control of
us by means of a tender offer, proxy contest, merger or otherwise, and thereby
to protect the continuity of our management. The issuance of shares of the
preferred stock pursuant to the board's authority described above may adversely
affect the rights of holders of common stock. For example, preferred stock
issued by us may rank prior to common stock as to dividend

                                       84
<PAGE>

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 common stock or may
otherwise adversely affect the market price of common stock.

  Series B Preferred Stock.

   The following summarizes the terms of the Series B Preferred Stock:

   Conversion. Holders of the Series B Preferred Stock may convert shares at
any time into common stock based upon an initial conversion price of $7,730 per
share ($7.73 per common stock equivalent share), subject to certain anti-

mergers, reorganizations, stock reclassifications, stock dividends, stock
splits and other similar events. All outstanding Series B Preferred Stock, as
well as one-half of all accumulated and unpaid dividends thereon, will be
converted automatically into common stock on the closing of this offering.

   Redemption. At the request of at least a majority of the holders of the
outstanding shares of Series B Preferred Stock, we are required to redeem for
cash the Series B Preferred Stock for the face value of $50 million plus all
accumulated but unpaid dividends if we have not completed a qualified offering,
liquidation or sale by July 23, 2006.

   Rank. Upon our liquidation, the Series B Preferred Stock ranks pari passu
with the Series C Preferred Stock and senior to the common stock and all other
classes or series of shares issued by us.

   Liquidation Preference. Shares of Series B Preferred Stock are entitled to a
liquidation preference equal to $50 million plus all accumulated but unpaid
dividends.

   Voting. Holders of the Series B Preferred Stock vote with the common stock
on an as-converted basis. However, the consent of the holders of 66 2/3% of the
shares of Series B Preferred Stock is required to:

  .redeem or repurchase any junior stock, except employee stock;

  .  authorize, create or issue any new class or series of debt securities
     or equity securities that is equal to or senior to the Series B
     Preferred Stock;

  .  adversely affect the rights of the Series B Preferred Stock;

  .  declare or pay a dividend or make any distribution with respect to any
     junior securities;

  .  increase or decrease the number of authorized or issued Series B
     Preferred Stock; and

     there is a change of control or a sale of all or substantially all of
     our assets.

convert into shares of common stock and the remaining dividends are either
payable in cash or shares of common stock, at our option.

   As a result of this offering, the outstanding shares of Series B Preferred
Stock will automatically convert into 6,642,621 shares of common stock.

any time into common stock, based upon an initial conversion price of $8.81 per
share, subject to certain anti-dilution provisions, including combinations or
consolidations of common stock, mergers, reorganizations, stock
reclassifications, stock dividends, stock splits and other similar events;
provided, however, that if the offering is consummated on or prior to October
20, 2000, the conversion price will be adjusted to the lesser of 75% of the
price per share in this offering or $14.13. All outstanding Series C Preferred
Stock, as well as one-half of all accumulated and unpaid dividends thereon,
will be converted automatically into common stock upon the closing of this
offering.

liquidation or sale by        , 2007.

   Rank. Upon our liquidation, the Series C Preferred Stock ranks pari passu
with the Series B Preferred Stock and senior to the common stock and all other

   Liquidation Preference. Shares of Series C Preferred Stock are entitled to a
liquidation preference equal to $12.0 million plus all accumulated but unpaid

  .  Declare or pay a dividend or make any distribution with respect to any
     junior securities;

                                       86
<PAGE>

     there is a change of control or a sale of all or substantially all of
     our assets.

   Dividends. The holders of the shares of Series C Preferred Stock are

<PAGE>

    and immediately exercisable, and expire on April 30, 2002. The shares
    of common stock under the warrants are subject to piggy-back
    registration rights.

Registration Rights

  Preferred Stock

   The terms of the Series B Preferred Stock and the Series C Preferred Stock
provide that the holders of the common stock issued upon conversion of, or as a
dividend on, Series B Preferred Stock and Series C Preferred Stock, as the case
may be, may require us to register that common stock under the Securities Act
of 1933 beginning no earlier than 180 days after the effective date of a
registration statement for an initial public offering of our common stock. We
will bear all registration expenses incurred in connection with the first two
of these demands for registration, provided they are at least 12 months apart.
Holders of common stock issued upon conversion of, or as a dividend on, Series
B Preferred Stock and Series C Preferred Stock also have the right to cause us
to register that common stock on Form S-3 when it becomes available to us if
they propose to register securities having a value of at least $5 million. We
will bear all registration expenses incurred in connection with an unlimited
number of these demands for registration, provided they are at least 120 days
apart.

   In addition, if we propose to register securities under the Securities Act,
other than registrations relating solely to employee benefit plans or corporate
reorganizations or other transactions under Rule 145 of the Securities Act,
then the holders of common stock issued upon conversion of, or as a dividend
on, Series B Preferred Stock or Series C Preferred Stock have a right, subject
to quantity limitations determined by underwriters if the offering involves an
underwriting, to request that we register such holders' common stock. If
holders of common stock issued upon conversion of, or as a dividend on, Series
B Preferred Stock or Series C Preferred Stock participate in that registration,
holders of common stock issued upon conversion of, or as a dividend on, Series
B Preferred Stock and Series C Preferred Stock will have priority over certain
other holders of common stock.

  Common Stock

   We have issued 58,332 shares of common stock with registration rights. If we
propose to register securities under the Securities Act, other than
registrations relating solely to employee benefit plans or corporate
reorganizations or other transactions under Rule 145 of the Securities Act,
then, the holders of these shares of common stock, subject to quantity
limitations determined by underwriters if the offering involves an
underwriting, have a right to request that we register such holders' common
stock. If these holders of common stock participate in that registration, they
will have priority over certain other holders of common stock. We will bear all
registration expenses and the holder of shares of common stock with these
registration rights will bear all selling expenses.

                                       88
<PAGE>

  Warrants

   We have issued four warrants for the purchase of a total of 30,000 shares of
common stock with registration rights. If we propose to register securities
under the Securities Act, other than registrations relating solely to employee
benefit plans or corporate reorganizations or other transactions under Rule 145
of the Securities Act, then, the holders of common stock issued upon exercise
of these warrants, subject to quantity limitations determined by underwriters
if the offering involves an underwriting, have a right to request that we
register such holders' common stock. If holders of common stock issued upon
exercise of the applicable warrants participate in that registration, holders
of common stock issued upon exercise of these warrants will have priority over
certain other holders of common stock. We will bear all registration expenses
and the warrant holder will bear all selling expenses.

   We have issued one warrant for the purchase of 474,160 shares of common
stock with registration rights. The holder of the common stock issued upon
exercise of the warrant may require us to register that common stock under the
Securities Act of 1933 beginning no earlier than 180 days after the effective
date of a registration statement for an initial public offering of our common
stock. We will bear all registration expenses incurred in connection with the
first two of these demands for registration, provided they are at least 12
months apart. The holders of common stock issued upon exercise of the warrant
also have the right to cause us to register that common stock on Form S-3 when
it becomes available to us if they propose to register securities having a
value of at least $5 million. We will bear all registration expenses incurred
in connection with an unlimited number of these demands for registration,
provided they are at least 120 days apart. In addition, if we propose to
register securities under the Securities Act, other than registrations relating
solely to employee benefit plans or corporate reorganizations or other
transactions under Rule 145 of the Securities Act, then, the holders of common
stock issued upon exercise of the warrant have a right, subject to quantity
limitations determined by underwriters if the offering involves an
underwriting, to request that we register such holders' common stock. If
holders of common stock issued upon exercise of the warrant participate in that

broad range of business combinations with a person or an affiliate or associate
of that person, who is an "interested stockholder" for a period of three years
from the date that person became an interested stockholder unless:

     directors of the corporation before the person becomes an interested
     stockholder;

  .  Upon consummation of the transaction, which resulted in the stockholder
     becoming an interested stockholder, the interested stockholder owned at
     least 85% of the voting stock of the corporation outstanding at the
     time the transaction is commenced, excluding for purposes of
     determining the number of shares outstanding those shares owned:

    -  By persons who are directors and officers; and

    -  By employee stock plans in which employee participants do not have
       the right to determine confidentially whether shares held subject
       to the plan will be tendered in a tender or exchange offer; or

  .  On or after the date the person becomes an interested stockholder, the
     business combination is approved by the corporation's board of
     directors and by the holders of at least 66 2/3% of the corporation's
     outstanding voting stock at an annual or special meeting, excluding
     shares owned by the interested stockholder. Under Section 203, an
     "interested stockholder" is defined as any person who is:

    -  The owner of 15% or more of the outstanding voting stock of the
       corporation; or

    -  An affiliate or associate of the corporation and who was the owner
       of 15% or more of the outstanding voting stock of the corporation
       at any time within the three-year period immediately prior to the
       date on which it is sought to be determined whether such person is
       an interested stockholder.

   The provisions of Section 203 could delay or frustrate a change in our
control, deny our stockholders the receipt of a premium on their common stock
and have an adverse effect on the common stock. The provisions also could
discourage, impede or prevent a merger or tender offer, even if such event
would be favorable to the interests of stockholders. Our stockholders, by
adopting an amendment to the certificate of incorporation, may elect not to be
governed by Section 203, which election would be effective 12 months after
adoption.

Limitations on Directors' Liability

   Delaware law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of directors' fiduciary duty of care. This duty of care
requires that, when acting on behalf of the corporation, directors must
exercise an informed business judgment based on all material information
reasonably available to them. Absent the limitations authorized by Delaware
law, directors could be accountable to corporations and their stockholders for
monetary damages for conduct that does not satisfy their duty of care. Although
Delaware law does not change directors' duty of care, it enables corporations
to limit available relief to equitable remedies such as injunction or
rescission. Our certificate of incorporation limits the liability of our
directors to us and our stockholders to the fullest extent permitted

                                       90
<PAGE>

by Delaware law. Specifically, our directors will not be personally liable for
monetary damages for breach of a director's fiduciary duty as a director,
except for liability for:

  .  Any breach of the director's duty of loyalty to us or our stockholders;

  .  Acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law;

  .  Unlawful payments of dividends or unlawful stock repurchases or
     redemptions as provided in Delaware General Corporation Law Section
     174; or

  .  Any transaction from which the director derived an improper personal
     benefit.

   The inclusion of this provision in our certificate of incorporation may have
the effect of reducing the likelihood of derivative litigation against
directors, and may discourage or deter stockholders or management from bringing
a lawsuit against directors for breach of their duty of care, even though such
an action, if successful, might otherwise have benefited us and our
stockholders.

Transfer Agent and Registrar

   The Transfer Agent and Registrar for the common stock will be First Union
National Bank.

                    UNITED STATES FEDERAL TAX CONSIDERATIONS
                      FOR NON-U.S. HOLDERS OF COMMON STOCK

   The following is a summary of the material United States federal income and
estate tax consequences of the ownership and disposition of our common stock
applicable to non-U.S. holders, as defined below. You are a "non-U.S. holder"
for United States federal income tax purposes if you are a beneficial owner of
our common stock and are any of the following:

  .  A nonresident alien individual as to the United States who is not a
     former citizen of the United States,

  .  A corporation, or other entity treated as a corporation under the United
     States Internal Revenue Code of 1986, as amended, and applicable
     treasury regulations, that is not created or organized under the laws of
     the United States or of any state,

  .  A partnership or other entity treated as a partnership under the United
     States Internal Revenue Code of 1986, as amended, and applicable
     treasury regulations, that is not created or organized under the laws of
     the United States or of any state,

  .  An estate that is not subject to United States federal income tax on a
     net income basis in respect of income or gain on the common stock, and

  .  A trust if either its administration is not subject to the primary
     supervision of a United States court or with respect to which no United
     States persons, as defined in the United States Internal Revenue Code of
     1986, as amended, have authority to control all substantial decisions of
     the trust.

   If you are an individual who is not a United States citizen, you should be
aware that the rules for determining whether you are a nonresident alien
individual as to the United States, subject to United States federal income and
estate taxation as described below, or a resident alien individual, subject to
United States federal income and estate taxation in the same manner as a United
States citizen, are highly complex. You may be a resident alien individual as
to the United States for United States federal income tax purposes for any year
if any of the following apply:

  .  You are a lawful permanent resident of the United States at anytime
     during the year,

  .  You have elected to be treated as a resident alien individual under the
     provisions of the United States Internal Revenue Code of 1986, as
     amended, and

  .  You are physically present in the United States for at least 31 days
     during the year and a number of other conditions are satisfied.

   You should consult your own tax advisors regarding your status as a non-U.S.
holder of our common stock.

                                       92
<PAGE>

   This discussion does not consider the specific facts and circumstances that
may be relevant to a particular non-U.S. holder in light of such holder's
personal investment or tax position. This discussion is not intended to be
applicable in all respects to all categories of non-U.S. holders, some of whom
may be subject to special treatment under United States federal income tax
laws, including "controlled foreign corporations," "passive foreign investment
companies," and "foreign person holding companies." In addition, it does not
address the treatment of holders of our common stock under the laws of any
state, local or non-United States taxing jurisdiction.

   This discussion is based on the federal tax laws of the United States,
including the Internal Revenue Code of 1986, as amended, applicable treasury
regulations, rulings and pronouncements of the United States Internal Revenue
Service and judicial decisions now in effect, all of which are subject to
change at any time. Any of these changes may be applied retroactively in a
manner that could cause the tax consequences to vary substantially from the
consequences described below, possibly having an adverse effect on a beneficial
owner of our common stock.

   You are urged to consult with your own tax advisors with regard to the
application of the federal income and estate tax laws to your particular
situation, as well as the applicability and effect of any state, local or non-
United States tax laws to which you may be subject.

Dividends

   We do not anticipate paying cash dividends on our common stock in the
foreseeable future. See "Dividend Policy." In the event, however, that
dividends are paid on shares of our common stock and you are a non-U.S. holder
of our common stock, your dividends are subject to withholding of United States
federal income tax at a 30% rate or at a lower rate that may apply to you under
an applicable income tax treaty. If you or a partnership in which you are a
partner maintain a permanent establishment or conduct a trade or business in
the United States, and the common stock is attributable to such permanent
establishment or effectively connected with such trade or business, dividends
on such stock may not be subject to withholding tax, provided that you satisfy
a number of certification requirements. Under such circumstances, dividends
would be taxed on a net income basis at the same graduated rates applicable to
United States citizens and resident alien individuals and United States
corporations. In general, you will not be considered to be engaged in a trade
or business in the United States solely as a result of your ownership of our
common stock.

   Dividends received by a non-U.S. holder that is a corporation may, in some
circumstances, be subject to an additional "branch profits tax" at a 30% rate
or at a lower rate that may apply to you under an applicable income tax treaty.

   Under currently effective United States treasury regulations, dividends paid
to an address in a foreign country are presumed to be paid to a resident of
that country, unless the payor has actual knowledge to the contrary, for
purposes of the 30% withholding tax discussed above. Under current
interpretations of these United States treasury regulations, this presumption
that dividends paid to an address in a foreign country are paid to a resident
of that country, unless the payor has actual knowledge to the contrary, also

                                       93
<PAGE>

applies for purposes of determining whether a lower rate of withholding tax
applies under an applicable income tax treaty.

   Under recently finalized United State treasury regulations (which we refer
to as the final withholding regulations), which will generally apply to
dividends paid after December 31, 2000, United States backup withholding tax at
a 31% rate will be imposed on dividends paid to non-U.S. holders if the
certification or documentary evidence procedures and requirements set forth in
such regulations are not satisfied directly or through an intermediary.
Further, if you claim the benefit of a lower rate of withholding tax under an
applicable income tax treaty, you must satisfy a number of certification
requirements. The final withholding regulations provide special rules for
dividend payments made to foreign intermediaries, United States or foreign
wholly-owned entities that are disregarded for United States federal income tax
purposes and entities that are treated as fiscally transparent in the United
States, the applicable income tax treaty jurisdiction, or both. For example, in
the case of our common stock held by a foreign partnership, the certification
requirements generally will apply to the partners of the partnership, and the
partnership itself will have to provide some information, including a United
States taxpayer identification number. The final withholding regulations also
provide look-through rules for tiered partnerships.

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

Gain on Disposition of Common Stock

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

  (1)Your gain on the common stock is attributable to a permanent
      establishment maintained in the United States by you or a partnership
      in which you are a partner, or under certain circumstances, your gain
      on the common stock is connected with the conduct of a trade or
      business in the United States by you or such partnership;

  (2)You are an individual and you or a partnership of which you are a
      partner holds the common stock as a capital asset, and you are present
      in the United States for 183 or more days during the year of the sale
      or other disposition and several other conditions are satisfied;

  (3)You are an individual who is a former citizen or long-term resident
      alien of the United States and are subject to tax pursuant to the
      provisions of the United States federal income tax laws applicable to
      United States expatriates; or

  (4)We are or have been a "United States real property holding corporation"
      for United States federal income tax purposes and you held, directly or
      indirectly, at any time during the five-year period ending on the date
      of the sale or other disposition, more than 5% of our total outstanding
      common stock, and you are not eligible for any exemption under an
      applicable income tax treaty.

                                       94
<PAGE>

   Generally, a corporation is a United States real property holding
corporation if the fair market value of its United States real property
interests equals or exceeds 50% of the sum of the fair market value of its
worldwide real property interests plus its other assets used or held for use in
a trade or business. We have not been, are not and do not anticipate becoming a
"United States real property holding corporation" for United States federal
income tax purposes.

   For a non-U.S. holder who is an individual and meets the requirements of
clause (1) or (3) above or a corporation that meets the requirements of clause
(1) above, taxable gains are taxed on a net income basis at the same graduated
rates applicable to United States citizens and resident alien individuals and
United States corporations. A non-U.S. holder who is an individual and who
meets the requirements of clause (2) above generally will be subject to a flat
30% tax on the gain derived from the sale. Thus, individual non-U.S. holders
who expect to spend a short period of time in the United States should consult
their tax advisors prior to the sale of our common stock to determine the
United States federal income tax consequences of the sale. In the case of a
sale or disposition by a non-U.S. holder where the requirements of clause (4)
above are met, the transferee of such stock will be required to withhold 10% of
the proceeds. Gains recognized by a non-U.S. holder that is a corporation may,
in some circumstances, be subject to an additional branch profits tax at a 30%
rate or at a lower rate that may apply to you under an applicable income tax
treaty.

Federal Estate Taxes

   Our common stock owned by an individual non-U.S. holder at the time of death
will be included in the holder's gross estate for United States federal estate
tax purposes and thus may be subject to United States federal estate tax, at
graduated rates of up to 55%, unless an applicable estate tax treaty provides
otherwise.

Information Reporting and Backup Withholding Tax

   In general, United States information reporting requirements and backup
withholding tax will not apply to dividends paid to you if you are either:

  .  Subject to the 30% withholding tax discussed above

      or

  .  Not subject to the 30% withholding tax because an applicable income tax
     treaty reduces or eliminates the withholding tax

although dividend payments to you will be reported to the Internal Revenue
Service for purposes of the withholding tax. See "--Dividends." If you do not
meet either of these requirements for exemption and you fail to provide
necessary information, including your United States taxpayer identification
number, or otherwise establish your status as an "exempt recipient," you may be
subject to backup withholding of United States federal income tax at a rate of
31% on dividends paid to you with respect to your common stock.

   Under current law, we may generally treat dividends paid to a payee with an
address outside the United States as exempt from backup withholding tax and
information reporting requirements unless we have actual knowledge that the
payee is a United States

                                       95
<PAGE>

person. However, under the final withholding regulations, dividends paid after
December 31, 2000, will generally be subject to backup withholding and
information reporting unless a number of certification requirements or
documentary evidence procedures, in the case of payments made outside the
United States with respect to an offshore account, are met. See "--Dividends"
for the rules applicable to foreign partnerships under the final withholding
regulations.

   United States information reporting requirements and backup withholding tax
generally will not apply to a payment of the proceeds of a sale or other
disposition of our common stock made outside the United States through an
office outside the United States of a non-U.S. broker, unless the non-United
States broker has a connection to the United States as specified by United
States federal tax law. However, United States information reporting
requirements, but not backup withholding tax, will apply to a payment of the
proceeds of a sale or other disposition of common stock made outside the United
States through an office outside the United States of a broker that:

  .  Is a United States person,

  .  Is a non-United States person who derives 50% or more of its gross
     income from all sources for certain periods preceding the year of the
     sale or other disposition from activities that are effectively connected
     with the conduct of a trade or business in the United States,

  .  Is a "controlled foreign corporation" as to the United States for United
     States federal income tax purposes,

      or

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

    -  one or more of its partners are United States persons, as defined
       in applicable treasury regulations, who in the aggregate hold more
       than 50% of the income or capital interests in the partnership,

             or

    -  the foreign partnership is engaged in the conduct of a trade or
       business in the United States

unless that broker receives a statement from the owner, signed under penalty of
perjury, certifying its non-United States status, and the broker has no actual
knowledge to the contrary, or the payee otherwise establishes its entitlement
to an exemption.

   Payment of the proceeds of a sale or other disposition of our common stock
through a United States office of a broker is subject to both United States
information reporting requirements and backup withholding tax at the rate of
31% unless the non-U.S. holder certifies as to its non-U.S. status under
penalties of perjury or otherwise establishes its entitlement to an exemption.

   Backup withholding is not an additional tax. A non-U.S. holder generally may
obtain a refund of any excess amounts withheld under the backup withholding
rules by filing a refund claim with the Internal Revenue Service.

                        SHARES AVAILABLE FOR FUTURE SALE

   The market price of the common stock may be adversely affected by the sale,

exemption provided by Rule 144. Sales of a large portion of the restricted
shares to be outstanding upon completion of this offering will be limited by
lock-up agreements.

Rule 144

   In general, under Rule 144, a stockholder who owns restricted shares that
have been outstanding for at least one year may sell, within any three-month
period, a number of these restricted shares that does not exceed the greater
of:

  .  1.0% of the then outstanding shares of common stock, or approximately
           shares immediately after this offering; or

  .  The average weekly trading volume of common stock on the Nasdaq National
     Market during the four calendar weeks before filing of a notice of the
     proposed sale is sent to the SEC.

   In addition, our affiliates must comply with the restrictions and
requirements of Rule 144, other than the one-year holding period requirement,
to sell shares of common stock that are not restricted securities. Sales under
Rule 144 are also governed by manner of sale provisions and notice
requirements, and current public information about us must be available.

   Under Rule 144(k), a stockholder who is not currently, and who has not been
for at least three months before the sale, an affiliate of ours and who owns
restricted shares that have been outstanding for at least two years, may resell
these restricted shares without following the above requirements. The one- and
two-year holding periods described above do not begin to run until the full
purchase price is paid by the person acquiring the restricted shares from us or
our affiliates.

   The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares offered by this
prospectus are subject to approval by their counsel of certain legal matters
and to certain other conditions. The underwriters are obligated to purchase and
accept delivery of all the shares of common stock offered by this prospectus,
other than those shares covered by the over-allotment option described below,
if any are purchased.

   An electronic prospectus will be available on the Web site maintained by

   The underwriters initially propose to offer the shares of common stock in
part directly to the public at the initial public offering price set forth on
the cover page of this prospectus and in part to certain dealers, including the
underwriters, at the initial offering price less a concession not in excess of
$   per share. The underwriters may allow, and the dealers may re-allow, to
other dealers a concession not in excess of $   per share. After the initial
offering of the common stock, the public offering price and other selling terms
may be changed by the representatives of the underwriters at any time without
notice. The underwriters do not intend to confirm sales to any accounts over
which they exercise discretionary authority.

   We have granted to the underwriters an option, exercisable within 30 days
after the date of this prospectus, to purchase from time to time, in whole or
in part, up to a total of    additional shares of common stock at the initial
public offering price less underwriting discounts and commissions. The
underwriters may exercise the option solely to cover over-allotments, if any,
made in connection with the offering. To the extent that the underwriters
exercise the option, each underwriter will become obligated, subject to a
number of conditions, to purchase its pro rata portion of such additional
shares based on such underwriter's percentage underwriting commitment as
indicated in the preceding table.

public offering price, $   of the shares included in the offering, to be sold
to some of our and our shareholders' directors, officers and employees and
friends and families of our and our shareholders' directors and executive
officers, to strategic partners and to other persons and entities that we
believe have contributed to the development and success of our business. The
number of shares available for sale to the general public will be reduced to
the extent these persons purchase reserved shares. Persons purchasing shares
under our directed share program must commit to purchase shares at the same
time as the general public. Any reserved shares that are not confirmed for
purchase within one day of the pricing of the offering will be offered by the
underwriters to the general public on the same terms as the shares offered in
our initial public offering.

liabilities, including liabilities under the Securities Act, or to contribute
to payments that the underwriters may be required to make. We and each of our

180-day period, we have also agreed not to file any registration statement with
respect to, and each of our executive officers, directors, stockholders and
option holders has agreed not to make any demand for, or exercise any right
with respect to, the registration of any shares of our common stock or any
securities convertible into or exercisable or exchangeable for common stock
without the prior written consent of Donaldson, Lufkin & Jenrette Securities
Corporation. However, Donaldson, Lufkin & Jenrette Securities Corporation may,
in its sole discretion, release all or any portion of the securities subject to
the lock-up agreements. We have determined that if the lock-up with respect to
a significant number of shares has been waived, whether with respect to a
single stockholder or a number of stockholders, we will review applicable
securities laws and, if public disclosure would be appropriate, disclose the
waiver. Prior to the offering, there has been no established trading market for
our common stock.

   The initial public offering price of the shares of our common stock offered
by this prospectus was determined by negotiation among us and the
representatives of the underwriters. The factors considered in determining the
initial public offering price included the history of and the prospects for the
industry in which we compete, our past and present operations, our historical
results of operations, our prospects for future earnings, the recent market
prices of securities of generally comparable companies and the general
condition of the securities markets at the time of the offering.

   Other than in the United States, no action has been taken by us or the
underwriters that would permit a public offering of the shares of common stock
offered by this prospectus in any jurisdiction where action for that purpose is
required. The shares of common stock offered by this prospectus may not be
offered or sold, directly or indirectly, nor may this prospectus or any other
offering material or advertisements in connection with the offer and sale of
any shares of common stock be distributed or published in any jurisdiction,
except under circumstances that will result in compliance with the applicable
rules and regulations of the particular jurisdiction. Persons with this
prospectus should inform themselves about and observe any restrictions relating
to this offering and the distribution of this prospectus. This prospectus does
not constitute an offer to sell or a solicitation of an offer to buy any shares
of common stock offered hereby in any jurisdiction in which such an offer or a
solicitation is unlawful.

   The following table shows the underwriting fees to be paid to the
underwriters by us in connection with this offering. These amounts are shown
assuming both no exercise and full of the underwriters' over-allotment option
described above.

   In connection with the offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of our common stock.
Specifically, the underwriters may over-allot the offering, creating a
syndicate short position. The underwriters may bid for and stabilize the price
of our common stock. In addition, the underwriting syndicate may reclaim
selling concessions from syndicate members and selected dealers if they
repurchase previously distributed common stock in syndicate covering
transactions, in stabilizing transactions or otherwise. These activities may
stabilize or maintain the market price of our common stock above independent
market levels. The underwriters are not required to engage in these activities
and may end any of these activities at any time.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
NETtel Communications, Inc.

   We have audited the accompanying consolidated balance sheets of NETtel
Communications, Inc. as of December 31, 1999 and 1998, and the related
consolidated statements of operations, stockholders' deficit, and cash flows
for each of the three years in the period ended December 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of NETtel
Communications, Inc. at December 31, 1999 and 1998, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1999, in conformity with accounting principles
generally accepted in the United States.

                                                          /s/ Ernst & Young LLP

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               December 31, 1999

1.The Company

    NETtel Communications, Inc. (the "Company" or "NETtel") is an integrated
communications provider, focused on medium-sized business customers in select
markets across the United States. The Company provides broadband Internet,
dedicated and switched long distance services and a suite of value-added data
and voice services.

    NETtel, a Delaware corporation, was incorporated on December 4, 1997, and
pursuant to a reorganization and exchange offer completed on December 30, 1997,
became the parent company of a wholly-owned operating subsidiary, NETtel
Corporation ("NETtel Corp."). NETtel Corp. was incorporated in the State of
Florida in February 1995.

2. Summary of Significant Accounting Policies

Basis of Presentation

    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary, NETtel Corp. All significant intercompany
balances and transactions have been eliminated in consolidation.

Use of Estimates

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

    The Company considers all highly liquid investments with a maturity of
three months or less at the time of purchase to be cash equivalents. The
Company has approximately $981,000 in restricted cash at December 31, 1999 and
1998. Restricted cash relates to letters of credit held by the Company for
future commitments the Company has entered into with various service providers.
For further information refer to Significant Relationships under Note 6.

Property and Equipment

    Property and equipment, which includes an Indefeasible Right of Use for
dark fiber, are stated at historical cost and are depreciated using the
straight-line method over the shorter of the asset's estimated useful life or
the lease term. These lives range from two to twenty years. Capital leases are
recorded at their net present value at the inception of the lease.

                          NETtel COMMUNICATIONS, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Intangible Assets

    Intangible assets are comprised of debt financing costs and are included in
other assets in the accompanying consolidated balance sheet. Debt financing
costs represent fees and other costs incurred in connection with the issuance
of long-term debt. Debt financing costs are amortized to interest expense over
the term of the related debt. As of December 31, 1999, the balance was
approximately $252,000, net of accumulated amortization of approximately
$40,000.

Revenue Recognition

    Revenue from communications services is generally recognized monthly as the
services are provided. Monthly recurring charges include fees paid by customers
for lines in service and any additional features on those lines. Usage charges
are billed in arrears and are fully earned as usage is accrued.

Cost of Revenue

    The Company's cost of revenue consists primarily of costs associated with
the origination, transport and termination of the Company's telecommunications
traffic.

Selling, General and Administrative Expense

    In 1998, the Company began marketing its services through three principal
sales channels, including direct sales, Branchising and independent agents.
Branchising is a cooperative relationship in which the Company partners with
independent telecommunications sales professionals who build sales teams to
sell NETtel's services exclusively in exchange for operational support and
sales commissions. The Branchise agreements generally have three year terms
under which the Company is committed to advancing limited funds to support
operating expenses for up to twelve months, provided that designated revenue
and employee targets are achieved. The Company currently expenses these
advances as they are made to the Branchises. In addition, the Branchises may
receive warrants to purchase shares of common stock upon the first, second and
third anniversaries of the effective dates of the contracts if certain
conditions are met.

Advertising Expense

    The Company expenses all advertising costs as incurred. The Company
incurred approximately $1.9 million, $2.9 million and $2.3 million in
advertising costs for the years ended December 31, 1999, 1998 and 1997,
respectively.

Net Loss Per Common Share

    The Company follows Statement of Financial Accounting Standards No. 128,
"Earnings Per Share," ("SFAS No. 128") for computing and presenting net loss
per share information. Basic net loss per share was determined by dividing net
loss by the weighted average number of common shares outstanding during each
year. Dilutive net loss per share excludes common equivalent shares,
unexercised stock options and warrants

                                      F-8
<PAGE>

                          NETtel COMMUNICATIONS, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
as the computation would be anti-dilutive. A reconciliation of the net loss
available for common stockholders and the number of shares used in computing
basic and diluted net loss per share is in Note 10.

Stock Options

    The Company has adopted Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" ("SFAS No. 123"). SFAS No. 123
allows companies to account for stock-based compensation either under the new
provisions of SFAS No. 123 or under the provisions of Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB No.
25"), but requires pro forma disclosure as if the measurement provisions of
SFAS No. 123 had been adopted. The Company has elected to account for its
stock-based compensation in accordance with the provisions of APB No. 25.

Income Taxes

    Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured by applying presently
enacted statutory tax rates, which are applicable to the future years in which
deferred tax assets or liabilities are expected to be settled or realized, to
the differences between the financial statement carrying amounts and the tax
bases of existing assets and liabilities. The effect of a change in tax rates
on deferred tax assets and liabilities is recognized in net income in the
period that the tax rate is enacted.

    The Company provides a valuation allowance against net deferred tax assets
if, based upon available evidence, it is more likely that some or all of the
deferred tax assets may not be realized.

Business Segments

    The Company has adopted Statement of Financial Accounting Standards No.
131, "Disclosure About Segments of an Enterprise and Related Information,"
which establishes standards for disclosures about products, geographics and
major customers. The Company's implementation of this standard did not have any
effect on its financial statements.

Fair Value of Financial Instruments

    The Company considers the recorded cost of its financial assets and
liabilities, which consist primarily of cash, accounts receivable, accounts
payable, debt and capital leases, to approximate the fair value of the
respective assets and liabilities. The Company performs credit evaluations of
the financial condition of certain of its customers and typically does not
require collateral from its customers.

Impairment of Long-Lived Assets

    The Company assesses the impairment of long-lived assets in accordance with
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of

                                      F-9
<PAGE>

                          NETtel COMMUNICATIONS, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
Long-Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS No.
121"). SFAS No. 121 requires impairment losses to be recognized for long-lived
assets when indicators of impairment are present and the undiscounted cash
flows are not sufficient to recover the assets' carrying amount. The impairment
loss of these assets is measured by comparing the carrying amount of the asset
to its fair value, with any excess of carrying value over fair value written
off. Fair value is based on market prices where available, an estimate of
market value or determined by various valuation techniques including discounted
cash flow.

Valuation Accounts

    A summary of the Company's allowance for bad debts is as follows:

</TABLE>

Reclassifications

    Certain amounts in the prior year's financial statements have been
reclassified to conform with the current year presentation.

Recent Pronouncements

    In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("SFAS No. 133"). SFAS No. 133 is effective for fiscal years
beginning after June 15, 2000 and cannot be applied retroactively. SFAS No. 133
establishes accounting and reporting standards requiring that every derivative
instrument be recorded in the balance sheet as either an asset or liability
measured at its fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. The Company plans to adopt SFAS No. 133
effective January 1, 2001.

   In June 1999, the FASB issued Interpretation No. 43, "Real Estate Sales, an
interpretation of SFAS No. 66". The interpretation is effective for sales of
real estate with property improvements or integral equipment entered into after
June 30, 1999. Under this interpretation, dark fiber is considered integral
equipment and accordingly title must transfer to a lessee in order for a lease
transaction to be accounted for as a sales-type lease. After June 30, 1999, the
effective date of FASB Interpretation No. 43, sales-type lease accounting is no
longer appropriate for dark fiber leases and therefore the Company's future
dark fiber transactions will be accounted for as operating leases unless title
to the fibers under lease transfers to the Company.

3. Debt

Gold & Appel Transfer S.A.

    In September 1998, the Company entered into a revolving line of credit with
the Company's largest stockholder, Gold & Appel Transfer, S.A. ("Gold &
Appel"), for $12,000,000. Interest accrued on unpaid balances at a rate of
12.25% per annum. During 1999, a total of $12.4 million of principal and
accrued interest was converted into a total of 1,943,241 shares of the
Company's common stock, at prices ranging from $6.17 per share to $6.49 per
share.

    In April 1999, the Company entered into a revolving bridge loan with Gold &
Appel for up to $8,000,000. Interest accrued on unpaid balances at a rate of
12% per annum. The Company borrowed a total of $8 million under this bridge
loan prior to the entire outstanding principal balance being converted to
Series B Preferred Stock on July 23, 1999.

    In September 1997, the Company obtained a revolving line of credit from
Gold & Appel for $650,000. Interest accrued on unpaid balances at a monthly
rate of 1%. An amendment to this agreement in October 1997 provided for an
additional $650,000 line of credit. The principal balance of $1,250,000 was
repaid in February 1998 and the accrued interest of $52,124 was contributed to
additional paid-in capital.

Williams Communications, Inc.

    On June 28, 1999, the Company entered into a Securities Purchase Agreement
(the "Securities Agreement") and a long-term Capacity Purchase Agreement (the
"Capacity Agreement") with Williams Communications, Inc ("Williams"). The
Capacity Agreement grants the Company a twenty year Indefeasible Right of Use
("IRU") for capacity on Williams' network, valued at approximately $60 million,
for which the Company will pay the net present value of approximately $25
million, payable $5 million upon signing the Capacity Agreement, and a seven-
year note with interest at 12% per annum, with principal and interest payable
in equal monthly installments of $350,399. At December 31, 1999, the balance
outstanding totaled approximately $18.9 million. The Company's IRU is included
in property and equipment in the accompanying consolidated financial
statements.

    Under the Securities Agreement the Company issued shares of Series A
Convertible Preferred Stock in exchange for $5 million in cash and $5 million
in network credits, which were used in the initial payment on the Capacity
Agreement. These shares were subsequently exchanged for Series B Preferred
Stock (see Note 4).

Nortel Networks, Inc.

    In July 1999, the Company entered into a credit agreement with Nortel
Networks, Inc. ("Nortel"). The agreement consists of a $120 million Advancing
Term Loan Facility (the "Nortel Term Loan"), and a $10 million Revolving Credit
Facility (the "Nortel

                                      F-11

Revolver", together the "Nortel Loan Agreements"). Under the Nortel Term Loan,
the Company may borrow funds to pay for equipment and services provided by
Nortel (the "Nortel Products"). For every dollar borrowed to fund Nortel
Products, the Company can borrow an additional 50 cents to pay for other
capital expenditures and operating costs related to the buildout of the
Company's network. The Nortel Revolver is for working capital and general
corporate purposes, borrowings against which are based on the balance of the
Company's eligible accounts receivable, as defined in the Nortel Loan
Agreements. At December 31, 1999, balances due to Nortel were as follows (in
thousands):

<TABLE>
      <S>                                                                <C>
      Nortel Term Loan.................................................. $18,056
      Nortel Revolver................................................... $ 3,565
</TABLE>

    Under the Nortel Loan Agreements, the Company may designate all or any
portion of the borrowings as either a floating base rate advance or a
Eurodollar rate advance with an applicable margin of 3.5% for a base rate
advance or 4.5% for a Eurodollar rate advance. The Nortel Loan Agreements
require compliance with certain financial and operating covenants. The
covenants also limit additional indebtedness and restrict the payment of cash
dividends and other distributions by the Company. At December 31, 1999, the
Company was in compliance with all of these covenants.

    In 1999, the Company incurred approximately $315,000 of interest expense on
the Nortel Loan Agreements, and the interest rates on the Agreements as of
December 31, 1999, ranged from 10.15% to 10.68125%. Principal payments under
the Nortel Loan Agreements are scheduled to begin in the fourth quarter of
2000, unless certain additional borrowing criteria are met, in which case
principal payments would begin in the fourth quarter of 2001.

Allied Capital Corporation

    In July 1999, together with the Nortel Loan Agreement, the Company entered
into a Term Loan Agreement with Allied Capital Corporation ("Allied") (the
"Allied Loan"). Under the terms of the Allied Loan, the Company borrowed $10
million from Allied, bearing interest at 12% per annum, with interest payable
monthly. The Allied Loan matures on July 30, 2006, and the balance outstanding
as of December 31, 1999 was $10 million.

    In connection with the Allied Loan, the Company issued a seven-year warrant
to purchase 474,160 shares of the Company's common stock for a nominal amount.
The value of the warrant of approximately $3.2 million has been reflected in
the accompanying financial statements as a discount to the Allied Loan, with
the corresponding amount included in additional paid-in capital. The discount
is being amortized as additional interest expense, using the effective interest
method over the life of the warrant, which is the same as the life of the
Allied Loan. The Company recorded interest expense of approximately $342,000 in
1999 related to the amortization of the discount.

4. Capital Stock

Common Stock

    On December 31, 1996, NETtel Corp. was converted from an S Corporation to a
C Corporation and the accrued interest on a note payable to the sole
stockholder was converted to equity. On January 20, 1997, $375,593 of the
principal balance of this note payable balance was also converted to equity
along with a $250,000 note payable to one of the Company's directors. This
amount is included in the issuance of common stock in the accompanying
Consolidated Statement of Stockholders' Deficit.

    On December 30, 1997, the stockholders of NETtel Corp. exchanged each share
of common stock in NETtel Corp. for fifteen shares of common stock in NETtel
Communications, Inc. Effective on this date, NETtel Corp. became a wholly-owned
subsidiary of NETtel Communications, Inc. Upon incorporation in December 1997,
the Company was granted the authority to issue 50 million shares of common
stock at a $0.0001 par value. In the consolidated financial statements, the
historical stockholders' equity of NETtel Corp. prior to the Reorganization has
been retroactively restated for the equivalent number of shares received in the
Reorganization, after giving effect to the difference in par value of NETtel
Corp.'s common stock of $0.01 per share and NETtel Communications' common stock
of $0.0001 per share by an offset to additional paid-in capital.

    On January 1, 1998, one of the stockholders returned 2,726,015 shares of
common stock to the treasury for an increase in compensation of $60,000. On
February 24, 1998, 1,791,000 shares of the treasury stock were reissued to
other investors for approximately $9.9 million. The remaining 935,015 treasury
shares were retired.

    In June 1998, two stockholders each purchased 770,000 shares of common
stock for an aggregate of $10,000,000. Attached to these shares of common stock
were warrants to purchase 1,185,800 shares of common stock at $6.49 per share,
exercisable over a five-year period. The warrants were exercised in April and
May 1999.

                          NETtel COMMUNICATIONS, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

    In September 1999, the Company completed a private placement of 58,332
shares of common stock for approximately $451,000.

Series B Redeemable Convertible Preferred Stock

    In July and August 1999, concurrent with their respective debt
arrangements, the Company issued Series B Preferred Stock to each of Gold &
Appel, Nortel and Allied. In addition, concurrent with these issuances, the
Series A Preferred Stock issued to Williams converted to Series B Preferred
Stock. Holders of the Series B Preferred Stock are entitled to receive an 8%
annual cumulative cash dividend payable semi-annually when and if declared by
the Company's Board of Directors. Holders of the Series B Preferred Stock are
entitled to certain voting rights.

    The Series B Preferred Stock has provisions entitling the holders to
convert the value of their stock into shares of the Company's common stock at
any time based upon an initial conversion price of $7,730 per share ($7.73 per
common stock equivalent share), subject to certain anti-dilution provisions.
Upon closing an initial public offering, as defined, the shares of Series B
Preferred Stock plus 50% of any unpaid dividends convert into shares of common
stock. The remaining dividends are either payable in cash or shares of common
stock at the option of the Company. If, on or before the seventh anniversary of
the issuance date, the Company has not completed an initial public offering, a
liquidation or a sale of the Company, then the holders of the Series B
Preferred Stock, have the right to redeem their shares for cash equal to $7,730
per share, subject to adjustment, plus all accumulated and unpaid dividends
thereon.

    Shares of the Series B Preferred Stock were issued as follows:

    The Company applies APB No. 25 in accounting for its stock incentive plan
and, accordingly, recognizes compensation expense for the difference, if any,
between the fair value of the underlying common stock and the grant price of
the option at the date of grant. The effect of applying SFAS No. 123's fair
value method to the Company's stock-based awards results in a net loss
attributable to common stockholders of approximately $52.9 million and $20.8
million, or a loss per share available for common stockholders of $3.26 and
$1.47 per share, for the years ended December 31, 1999 and 1998, respectively.
The fair value of options granted in 1999, used as a basis for the above pro
forma disclosures, was estimated as of the date of grant using the Black-
Scholes option value method with the following weighted-average assumptions:
dividend yield of 0%; risk-free interest rate of 6.5%; volatility of 0.5; and
expected life of the option of 10 years.

    The effect of applying SFAS No. 123 on 1999 and 1998 pro forma net loss as
stated above is not necessarily representative of the effects on reported net
loss for future years due to, among other things, the vesting period of the
stock options and the fair value of additional stock options granted in future
years.

    On April 7, 1999, the Company adopted an employee stock purchase plan (the
"ESPP") which provides for the issuance of up to 500,000 shares of common
stock. The ESPP is intended to qualify under Section 423 of the Internal
Revenue Code and provides the Company's employees with an opportunity to
purchase shares of common stock through payroll deductions.

    The weighted average fair values of the warrants granted during 1999 was
estimated as $6.17 per share for warrants granted with exercise prices below
the fair market value of the stock on the date of grant using the Black-Scholes
option-pricing model with the following assumptions: dividend yield 0%; risk-
free interest rate of 6.5%; volatility of 0.5; and expected lives from one
month to seven years. The weighted average fair values of the warrants granted
during 1999 was estimated as $2.44 per share for warrants granted with exercise
prices above the fair market value of the stock on the date of grant using the
Black-Scholes option-pricing model with the following assumptions: dividend
yield 0%; risk-free interest rate of 6.5%; volatility of 0.5; and expected
lives from one to five years.

    The weighted average fair values of the warrants granted during 1998 was
estimated as $1.31 per share, using the Black-Scholes option-pricing model with
the following assumptions: dividend yield of 0%; risk-free interest rate of
6.5%; volatility of 0.5; and expected lives of 5 years for warrants issued in
1999 and five years.

    The Company has issued, or has committed to issue warrants to purchase
shares of the Company's common stock to certain non-employees. Pursuant to the
terms of SFAS No. 123, stock-based compensation expense has been recorded
reflecting the value of the warrants issued or expected to be issued.

6. Significant Relationships

    On April 10, 1998, the Company signed a 30-month carrier services
switchless contract with Frontier Communications of the West, Inc.,
("Frontier") for a monthly commitment of $250,000. During 1999, the Company met
this commitment and paid approximately $14.0 million to Frontier. In addition,
the Company has $200,000 in restricted cash in favor of Frontier at December
31, 1999.

    The Company entered into a 5 -year sub-Carrier Identification Code contract
on August 13, 1996 with Telco Communications Group ("Telco"), which was
subsequently merged with Excel Communications, Inc., for termination of long
distance traffic throughout the United States. For the years ended December 31,
1999 and 1998, approximately 5% and 42%, respectively, of the Company's total
revenue was received through Telco, and the remaining revenue came from direct
billings to commercial customers. At December 31, 1999 and 1998, the Company
had receivables of approximately $0 and $1.1 million, respectively, and
payables of approximately $387,000 and $324,000, respectively, with Telco and
its successor companies.

    In April 1998, the Company entered into a four year Branded Services
Agreement with Epoch Networks, Inc. (the "Epoch Agreement"). Two of NETtel's
directors are stockholders of Epoch. Under the Epoch Agreement, the Company,
under the NETtel brand name, is authorized to provide and resell a variety of
Internet access and related services provided by Epoch. The Epoch Agreement
requires the Company to pay a specified monthly minimum revenue commitment of
$50,000. During 1999, the Company met this commitment and paid approximately
$1.8 million to Epoch.

7. Commitments and Contingencies

Capital Leases

    The Company has entered into capital leases for the purchase of various
office, computer and network equipment. Interest rates on the capital leases
range from 3.9% per annum to 10.6% per annum. Capital lease amortization is
included in depreciation and amortization expense and accumulated depreciation
in the accompanying consolidated financial statements.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

    In conjunction with one of the capital leases entered into in 1999, the
Company issued two warrants to purchase up to 17,500 shares of common stock at
an exercise price of $8.00 per share. The value of this warrant has been
determined based on a Black-Scholes valuation, and has been recorded as a
discount to the capital lease, with an offset to additional paid-in capital,
and the discount is being amortized to interest expense over the 3 1/2 year
life of the lease.

Operating Leases

    The Company leases office space for its headquarters location and various
sales offices, as well as space for its switch locations. In addition, the
Company has entered into operating leases for certain office, computer and
network equipment. Total rent expense for 1999, 1998 and 1997 was approximately
$2.2 million, $828,000 and $55,000, respectively.

Contingencies

    From time to time, the Company and its subsidiary are party to ordinary
routine litigation incidental to their business. Management believes that the
outcome of such lawsuits will not have a material adverse impact on the
Company's consolidated financial statements.

8. Taxes

    The Company files its income tax returns on the cash basis and this
difference, as well as the net operating loss carryforwards described below, is
the principal difference between financial statement and tax basis.

    At December 31, 1999 the Company had net operating loss carryforwards of
approximately $59.3 million. The timing and manner in which the operating loss
carryforwards may be utilized in any year will be limited to the Company's
ability to

generate future earnings. Current net operating loss carryforwards will expire
in various years through 2019. As the Company has not generated earnings and no
assurance can be made of future earnings, a valuation allowance in the amount
of the net deferred tax assets has been recorded. The change in the valuation
allowance was approximately $20.5 million from December 31, 1998 to December
31, 1999.

Item 14. Indemnification of Directors and Officers.

   Under Section 145 of the Delaware General Corporation Law, a corporation may
indemnify its directors, officers, employees and agents and its former
directors, officers, employees and agents and those who serve, at the
corporation's request, in such capacities with another enterprise, against
expenses (including attorney's fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding in which they or
any of them were or are made parties or are threatened to be made parties by
reason of their serving or having served in such capacity. The Delaware General
Corporation Law provides, however, that such person must have acted in good
faith and in a manner such person reasonably believed to be in (or not opposed
to) the best interests of the corporation and, in the case of a criminal
action, such person must have had no reasonable cause to believe his or her
conduct was unlawful. In addition, the Delaware General Corporation Law does
not permit indemnification in an action or suit by or in the right of the
corporation, where such person has been adjudged liable to the corporation,
unless, and only to the extent that, a court determines that such person fairly
and reasonably is entitled to indemnity for costs the court deems proper in
light of liability adjudication. Indemnity is mandatory to the extent a claim,
issue or matter has been successfully defended.

   Our By-laws provide that, to the extent permitted by law, we shall fully
indemnify any person who is or was a party or is threatened to be made a party
or is otherwise involved in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he or she
is or was a director or an officer of ours or is or was serving at our request
as a director, officer, employee of another corporation, partnership, joint
venture, trust or other enterprise, whether the basis of the proceeding is
alleged action in an official capacity as a director, officer, employee or

                                      II-1
<PAGE>

agent or in any other capacity while serving as a director, officer, employee
or agent against all expense, liability and loss reasonably incurred by him or
her. However, if the indemnitee initiated the action, suit or proceeding, we
will only indemnify him or her if the action, suit or proceeding was
authorized by our board of directors.

   Under our By-laws, we are also obligated to advance expenses to the
indemnitee incurred in his or her defense. If required by law, the indemnitee
must undertake to repay us if there is a final determination that he or she
was not entitled to indemnification. If we do not fully pay the indemnitee
within 60 days of receiving a written claim for indemnification, the
indemnitee has the right to sue us to recover the amount to of the claim. The
indemnification rights under our By-laws are not the indemnitee's exclusive
indemnification rights and we may indemnify the indemnitee pursuant to a
statute, our amended and restated certificate of incorporation, an agreement,
the vote of our stockholders or disinterested directors or otherwise. In
addition, we may purchase insurance to indemnify the indemnitees. Our By-laws
also permit us to indemnify and advance expenses associated with the
indemnification to any of our employees or agents.

Item 17. Undertakings.

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

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the 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 a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                      II-4
<PAGE>

   The undersigned Registrant hereby further undertakes that:

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

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