                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND BASIS OF PRESENTATION:

   References in these footnotes to "Convergent Communications," "us," "we,"
"our" refer to Convergent Communications, Inc. and its subsidiaries.

   Convergent Communications is a single-source provider of data and voice
communications systems, services and solutions to small and medium sized
businesses. We design, build, install, manage and monitor data and voice
networks inside enterprises and provide external network services such as data
transport, long distance, local service and Internet access. We offer these
products and services on a stand-alone basis or as part of a bundled offering
that can include owning an enterprise's internal data and voice networks. We
are also installing an integrated data and voice switching platform in each of
the markets in which we operate to efficiently handle our customers' traffic.
We provide the following products and services:

  .  Data Services

  .  Voice Services

  .  Enterprise Network Services

  .  Data Products

  .  Voice Products

   Our ultimate success depends upon, among other factors, establishing our
nationwide network, funding the development of our enterprise networks,
continuing to develop our customer care and sales organizations, integrating
acquired businesses, attracting and retaining customers, continuing to develop
and integrate our operational support system and other back office systems,
responding to competitive developments, continuing to attract, retain and
motivate qualified personnel, and continuing to upgrade our technologies and
commercialize our services incorporating these technologies. There is no
assurance that we will be successful in addressing these matters and our
failure to do so could have a material adverse effect on our business
prospects, operating results and financial condition.

   Our business plan will continue to require a substantial amount of capital
to fund our expansion of our existing and acquired markets. As we continue to
expand our business, we will seek additional sources of financing to fund our
development. We estimate that our existing funds at June 30, 1999, the
proceeds from our July initial public offering, our available borrowing and
lease financing capacity and the proceeds from the exercise of warrants in
July will be sufficient to meet our capital requirements for the foreseeable
future. We could, however, require additional capital sooner due to material
shortfalls in our operating and financial performance or if we are more
aggressive in our expansion than currently contemplated. We cannot be certain
that we would be successful in raising sufficient debt or equity capital to
fund our operations on a timely basis or on acceptable terms. If needed
financing were not available on acceptable terms, we could be compelled to
alter our business strategy, or delay or abandon some of our future plans or
expenditures or fail to make interest payments on our debt. Any of these
events would have a material adverse effect on our financial condition,
results of operations and liquidity.

2. INTERIM FINANCIAL DATA:

   The consolidated balance sheet as of June 30, 1999, statement of
shareholders' deficit for the six months ended June 30, 1999 and the
consolidated statements of operations and comprehensive loss, and cash flows
for the three and six months ended June 30, 1998 and 1999 have been prepared
by us without audit. In our opinion, all adjustments, consisting of only
normal recurring adjustments, necessary to present fairly the consolidated
financial position, results of operations and cash flows have been made. The
results of operations for these interim periods are not necessarily indicative
of the results for the full year.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  The accompanying financial statements should be read with our consolidated
financial statements included in our 1998 Form 10-K filed with the Securities
and Exchange Commission on March 16, 1999.

  Certain prior period amounts have been reclassified to conform to the
current period's presentation.

3. ACQUISITIONS:

   Kansas Communications, Inc. In February 1999, we acquired the assets and
assumed certain liabilities of Kansas Communications, Inc. ("KCI"). KCI was a
telecommunications equipment provider and integrator. The purchase price
consisted of $1.5 million in cash, $4.5 million in notes payable and 24,925
shares of our common stock, which, for purchase accounting purposes, were
assigned a value of $10.00, and assumed liabilities of $2.4 million resulting
in total consideration of $8.7 million. In April 1999, $1.5 million of the
notes payable were paid with the proceeds from the sale of our Series A
Convertible Preferred Stock. An additional $2.0 million was paid subsequent to
June 30, 1999.

   BSSi Innovations, Inc. In April 1999, we acquired BSSi Innovations, Inc.
("BSSi"). BSSi was a data network integration services provider based in
Chicago, Illinois. The purchase price consisted of $455,000 in cash, 37,000
shares of our common stock, which for purchase accounting purposes were
assigned a value of $10.00 per share, and assumed debt of approximately
$525,000, resulting in total consideration of $1.4 million. An additional
10,000 shares may be issued if certain financial conditions are met.

   Choice Solutions, Inc. In June 1999 we entered into an agreement to purchase
the majority of the assets and assume certain liabilities of Choice Solutions,
Inc. ("CSI"). In addition, in June, we entered into a Management Agreement
with CSI which gives us effective control of the operations of CSI. Our
financial statements include the accounts and results of operations from the
effective date of the management agreement. Subsequent to June 30, 1999 we
completed the acquisition of the majority of the assets and certain
liabilities of CSI. CSI was a data network integration services provider based
in Dallas, Texas. The purchase price consisted of $1,125,000 in cash and
15,000 shares of our common stock valued at $225,000, resulting in total
consideration of $1,350,000. Additional shares of our common stock may be
issued if certain financial results are attained. As of June 30, 1999 we had
recorded a liability for the acquisition of $1,350,000.

   We accounted for each of these acquisitions as a business combination using
the purchase method of accounting. In connection with the acquisitions, the
excess of consideration given over the fair market value of the net assets
acquired is being amortized on a straight line basis over the estimated life
of the intangible asset acquired which is ten years. The accompanying
financial statements include the accounts of the acquired companies from the
effective dates of the acquisitions.

4. CREDIT FACILITY:

   In June 1999, we entered into a $10.0 million senior secured credit facility
with Goldman Sachs Credit Partners L.P. The proceeds of this facility will be
used for working capital and other general corporate purposes. Interest
accrues at the greater of 13.0% or LIBOR plus 6.0% with interest payments due
monthly. The principal amount outstanding along with any accrued interest is
due in June, 2002. We cannot re-borrow amounts repaid under this facility. In
connection with this facility, we also issued to Goldman Sachs Credit Partners
L.P. a warrant to acquire 375,000 shares of common stock at an exercise price
of $15.00 per share. As of June 30, 1999 we had borrowed the full amount
available under this facility.

5. SERIES A PREFERRED STOCK:

   In March 1999, we sold 800,000 shares of Series A Convertible Preferred
Stock and warrants to purchase 958,333 shares of our common stock to various
affiliates of the Sandler/21st Century Group for total consideration of $20.0
million. The Series A Convertible Preferred Stock automatically converted into
2,666,677 shares of common stock upon the completion of our initial public
offering which closed on July 23, 1999. The proceeds from the sale, net of
related offering costs were $19.2 million. One of our directors, Michael
Marocco, is a principal of several of the entities in Sandler Capital. Mr.
Roland Casati, another director, also purchased shares of Series A Convertible
Preferred Stock.

  We have 1,000,000 shares of preferred stock authorized none of which were
outstanding as of December 31, 1998 and 800,000 of which were outstanding as
of June 30, 1999.

6. BUSINESS SEGMENTS:

   We classify our business into five fundamental areas: data services, voice
services, Enterprise Network Services, data products and voice products.
Senior management evaluates and makes operating decisions about each of these
operating segments based on a number of factors. We do not account for assets
by business segment

and, therefore, depreciation and amortization are not factors used in
evaluating operating performance. Two of the more significant factors used in
evaluating our operating performance are: revenue and gross margin before
depreciation as presented below:

8. SUBSEQUENT EVENTS:

   On July 20, 1999, we completed a one-for-two reverse split of our common
stock. The accompanying consolidated financial statements and related
disclosures have been restated for all periods presented to reflect the
reverse stock split.

   In July 1999, we entered into a six-year $103.5 million credit facility with
Cisco Systems Capital Corporation. This credit facility will provide the
financing for the purchase and installation of our Cisco Systems, Inc. multi-
service data and voice switching platform and for other Cisco equipment. Under
the terms of this agreement, Cisco Systems, Inc. also received a warrant to
purchase 575,000 shares of our common stock. The warrant has an exercise price
of $15.00 per share and is exercisable for three years from the date of
issuance. The facility will be available in three tranches over a three year
period with quarterly payments due over three years beginning one year from
the availability of each tranche.

   In July 1999, we completed an initial public offering of our common stock in
which 9,660,000 shares, including 723,271 shares sold by selling shareholders,
were sold at an offering price of $15.00 per share. We received proceeds from
the offering of approximately $122.7 million, net of selling shareholders
($10.8 million), underwriting discount ($10.1 million), and offering expenses
($1.2 million).

9. LEASE ACCOUNTING:

   In November 1999 we concluded that we should have accounted for certain data
and voice product leasing transactions provided to our customers through our
leasing subsidiary, Convergent Capital Corporation, as sales type lease
transactions in accordance with Statements of Financial Accounting Standards
No.'s 13 and 94. The effect of this adjustment was to increase revenue by $1.4
million, increase cost of sales, excluding depreciation by $1.1 million and
reduce net loss by approximately $368,000 for the three months ended June 30,
1999 and increase revenue by $2.7 million, increase cost of sales, excluding
depreciation by approximately $1.7 million and reduce net loss by
approximately $1.0 million for the six months ended June 30, 1999, as
presented below:

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

  The following discussion should be read in conjunction with the Consolidated
Financial Statements and the accompanying footnotes included in this Form 10-
Q. This discussion includes forward-looking statements and is based on current
expectations which involve risks and uncertainties. Because of the uncertainty
of many factors, what actually occurs in the future may be very different from
what we project in our forward-looking statements.

Overview

  We are a rapidly growing national provider of single-source data and voice
communications systems, services and solutions primarily to businesses with 25
to 500 employees. Inside our customers' premises we own communications
networks and provide professional services, such as the design, installation,
management and monitoring of those networks to our customers. Outside our
customer' premises, we provide a full range of data and voice transport
services. By operating networks, both inside and outside our customers'
premises, and by offering a broad range of data and voice products and
services, we enable small and medium sized businesses to use state-of-the-art
communications solutions, including data and voice networks based on Internet
Protocol, electronic commerce, the Internet and sophisticated communications
systems. We offer each of our products and services on a stand-alone basis and
are now offering a bundled communications solution, which we call Enterprise
Network Services, in which we design, install, own, manage and monitor the
data and voice networks inside our customers' premises and provide
communications services outside our customers' premises.

  We were first capitalized on March 1, 1996. Since that time, we have
successfully raised $338.6 million in capital, including $450,000 in founder's
capital, $24.0 million in two private placements of common stock in 1996 and
1997 (including an additional $450,000 from the founders), $160.0 million
through the 1998 sale of our 13% Senior Notes and related warrants, $20.0
million in a 1999 sale of our convertible preferred stock and warrants to
affiliates of Sandler Capital and $134.1 million in our July 1999 initial
public offering of common stock. As a result of the investment in our
preferred stock, we also have increased the borrowing capacity under our
existing Comdisco equipment lease facility by $20.0 million to a total of
$30.0 million. In addition, in June 1999, we entered into a $10.0 million
senior secured credit facility with Goldman Sachs Credit Partners L.P. and in
July we entered into a six year $103.5 million equipment financing facility
with Cisco Systems Capital Corporation.

  In the last three years, we completed 15 strategic acquisitions, the most
significant of which was the 1998 acquisition of substantially all of the
assets of Tie Communications, Inc. at a cost of approximately $51.4 million.
With the acquisition of these assets, we accelerated our growth by adding 24
new markets and 452 employees with experience in voice products and services.
This acquisition also gave us the opportunity to cross-market our data
products and services, including Enterprise Network Services, to the
approximately 77,000 customers that purchased products or services from Tie in
the past.

  We began offering Enterprise Network Services in December 1997 and have now
entered into long-term Enterprise Network Service contracts with 23 customers.
We expect these contracts will provide us with approximately $16.2 million in
total revenue over their terms. Although these contracts may be canceled by
the customer, exposing us to risks related to remarketing, cancellation
requires payment of a fee designed to reimburse us for all or substantially
all of our costs incurred in entering into the contract.

Description of Financial Components

  We classify our business into five segments: data services, voice services,
Enterprise Network Services, data products and voice products.

  Selling, general and administrative expenses have increased significantly
and will continue to increase as we recruit additional management and support
personnel necessary for continued growth. The Tie acquisition contributed
substantially to this increase. However, we expect these expenses to decline
as a percentage of our revenue as we expand our customer base and begin
selling additional products and services in each of our markets.

  .  Sales and marketing expenses include commissions paid in connection with
     our sales programs, marketing salaries and benefits, travel expenses,
     trade show expenses, consulting fees and promotional costs. Also
     included are the costs of soliciting potential customers such as
     telemarketing, brochures, targeted advertising and promotional
     campaigns. We expect these expenses to increase as we add additional
     sales and marketing personnel and further implement our business plan.

  .  General and administrative expenses primarily consist of salaries and
     related expenses of management and support services personnel, occupancy
     fees, professional fees and general corporate and administrative
     expenses. We also include costs associated with the development, support
     and expected enhancements of our operational support software platform,
     to the extent these costs are not capitalized.

  Depreciation and amortization expense includes depreciation of property,
network and equipment (over two to five years), including our assets located
inside our customers' premises provided under Enterprise Network Services
contracts. Amortization expense includes the amortization of intangible assets
(over three to ten years), primarily goodwill (over ten years), that result
from business acquisitions. We had $50.1 million of goodwill, net of
amortization, on June 30, 1999. Depreciation and amortization will increase as
we install additional ePOP switching platforms and expand our Enterprise
Network Services business and as a result of increased amortization of
intangibles expected to result from future acquisitions.

  Interest expense includes interest expense on our short-term and long-term
debt, including capital leases. The majority of the interest expense is
related to our 13% Senior Notes which mature in 2008. Interest expense will
increase as we continue to finance a significant portion of our capital
expenditures, including our purchase of Cisco Systems Inc.'s multi-service,
data and voice switches and additional Cisco equipment under the
$103.5 million equipment facility with Cisco Systems Capital Corporation and
as a result of the Goldman Sachs Credit Facility.

Results of Operations

  Management evaluates and makes operating decisions about each of our
operating segments based on a number of factors. Two of the more significant
factors we use in evaluating operating performance are: revenue and gross
margin before depreciation. We do not account for assets by business segment
and, therefore, depreciation and amortization are not factors used by
management in evaluating operating performance.

Summary Quarterly Financial Data

  The table below presents unaudited quarterly statement of operations data
for each of the nine quarters through June 30, 1999. This information has been
derived from unaudited financial statements that have been prepared on the
same basis as the audited financial statements contained in our 1998 Form 10-K
and, in our opinion, includes all adjustments, consisting only of normal
recurring adjustments, that we consider necessary for a fair presentation of
the information. The operating results for any quarter are not necessarily
indicative of results for any future periods.

(1) EBITDA consists of earnings before interest (net), income taxes,
    depreciation and amortization and other income (expense). EBITDA is a
    measure commonly used to analyze companies on the basis of operating
    performance. It is not a measure of financial performance under GAAP and
    should not be considered as an alternative to net income (loss) as a
    measure of performance or as an alternative to cash flow as a measure of
    liquidity. Our measure of EBITDA may not be comparable to similarly titled
    measures used by other companies.

  We have generated greater revenue in each successive quarter since our
inception, reflecting increases in the number of customers, mainly due to
acquisitions, and in sales to existing customers. Cost of sales excluding
depreciation has increased in every quarter, reflecting product and service
costs directly associated with the increases in revenue. Our selling, general
and administrative expenses have increased in every quarter and reflect sales
and marketing costs such as sales commissions, and the development and growth
of regional and corporate support staff. Depreciation and amortization
increased in each quarter through December 31, 1998 and again in the quarter
ended June 30, 1999. The increases in depreciation are due to the purchase of
property, network and equipment both inside and outside our customers'
premises associated with our expansion from one to 35 markets since inception,
and due to the deployment of our multi-service data and voice switching
platform in three markets. The increases in amortization are due to the
increase in goodwill and other intangible assets resulting from the completion
of 15 acquisitions through June 30, 1999. We have also experienced increasing
operating and net losses every quarter. However, net loss has declined as a
percentage of revenue from 79% for the second quarter of 1997 to 60% of
revenue for the second quarter of 1999.

Results of Operations

  Revenue for the second quarter of 1999 was $30.1 million greater than
revenue for the second quarter of 1998 and revenue for the six months ended
June 30, 1999 was $55.3 million greater than revenue for the six months ended
June 30, 1998. The increase in revenue was primarily due to the addition of 27
new markets through acquisitions between June 30, 1998 to June 30, 1999. The
increase in revenue was also due to internal growth of our operations and
sales staff. Our most significant acquisition was the acquisition of the
assets of Tie Communications, which occurred in the third quarter of 1998. The
Tie acquisition contributed to the sizable increase in voice services revenue
and voice product revenue. The increase in data products was primarily a
result of the development and growth of existing markets and a result of the
expansion of data services markets from

eight at June 30, 1998 to 13 at June 30, 1999. As a result of the Tie
acquisition, and our continued strategy to increase our service offerings, our
overall revenue mix shifted from approximately 29% in services for the six
months ended June 30, 1998, to 46% for the six months ended June 30, 1999 and
44% in services for the second quarter of 1999. A significant factor in our
strategy to increase services is through our Enterprise Network Services
offering. As of June 30, 1999 we had 23 customers, representing $16.2 million
in revenue over the terms of their contracts compared to 13 customers and
$11.9 million in contract term revenue as of June 30, 1998.

  Cost of sales excluding depreciation increased $17.9 million from the second
quarter of 1998 to the second quarter of 1999 and increased $33.9 million from
the six months ended June 30, 1998 to the six months ended June 30, 1999,
while declining as a percentage of total revenue from 73% for the six months
ended June 30, 1998 to 64% for the six months ended June 30, 1999 and to 62%
for the second quarter of 1999. This decline as a percentage of total revenue
is a reflection of the decline in cost of sales excluding depreciation for
both products and services. Cost of product sales excluding depreciation
declined as a percentage of product revenue, from 79% for the second quarter
of 1998 to 74% for the second quarter of 1999 and from 80% for the first six
months of 1998 to 74% for the first six months of 1999. This decrease as a
percentage of product revenue is due to an increase in sales of voice products
which have a lower related cost of sales excluding depreciation than data
products. Cost of service sales excluding depreciation as a percentage of
service revenue, decreased from 57% for the second quarter of 1998 to 47% for
the second quarter of 1999 and from 54% for the first six months of 1998 to
51% for the first six months of 1999. The decrease in cost of service sales
excluding depreciation as a percentage of service revenue was primarily due to
an increase in in our offering of professional services such as network and
web, design, maintenance and monitoring which have a lower related cost.

  Selling, general and administrative expenses increased $19.7 million from
the second quarter of 1998 to the second quarter of 1999 and increased $37.0
million from the six months ended June 30, 1998 to the six months ended June
30, 1999. However, selling, general and administrative expenses declined as a
percentage of revenue from 95% for the first six months of 1998 to 73% for the
first six months of 1999 and further declined to 72% of revenue for the second
quarter of 1999. We expect selling, general and administrative expenses to
continue to decrease as a percentage of revenue as we expand our customer base
and begin selling additional products and services in each of our markets.

  The increases in selling, general and administrative described above were
primarily a result of:

  .  the expansion from eight to 35 markets;

  .  the completion of three acquisitions;

  .  an increase from 274 employees at June 30, 1998 to 1,206 at June 30,
     1999 (452 of which were hired as a result of the Tie acquisition); and

  .  continued growth of the support services organization required to
     support expanding field operations, which accounted for approximately
     $12.5 million or 46% of total selling, general and administrative
     expenses for the three months ended June 30, 1999 and $23.7 million or
     47% of total selling, general and administrative expenses for the six
     months ended June, 1999.

  Depreciation and amortization expense increased approximately $2.9 million
from the second quarter of 1998 to the second quarter of 1999 and increased
$5.0 million from the first six months of 1998 to the first six months of
1999. These increases are a direct result of increases of $30.1 million in
property, network and equipment. In addition, goodwill increased $45.4 million
as a result of the acquisitions completed between June 30, 1998 and June 30,
1999 and other intangible assets increased $3.2 million. As of June 30, 1999
we had

               CONDITION AND RESULTS OF OPERATIONS--(Continued)

$50.1 million in goodwill, net of amortization, which is being amortized over
ten years. The increase in property, network and equipment is largely due to:

  .  the expansion from eight to 35 markets;

  .  the development and deployment of our multi-functional, integrated data
     and voice switching platform

  .  continued development of our operational support system;

  .  the increase in assets managed under Enterprise Network Services
     contracts; and

  .  office equipment and furniture related to the growth of our support
     services organization.

  Interest expense increased by approximately $320,000 from the second quarter
of 1998 to the second quarter of 1999 and increased $6.2 million from the six
months ended June 30, 1998 to the six months ended June 30, 1999. The large
increase for the six month periods is primarily a result of a full six months
of interest expense in 1999 compared to three months of interest in 1998 on
$160.0 million in principal amount of our 13% Senior Notes issued in April
1998. The increase is also a result of assumed indebtedness from acquisitions
and increased indebtedness under our equipment financing facilities with
Comdisco and Sun Financial Group, Inc. due to property, network and equipment
purchased for our networks both inside and outside our customers' premises.

  Interest expense will increase as we continue to finance a significant
portion of our capital expenditures, including equipment purchased for
installation at our customers' offices in connection with the provision of
Enterprise Network Service, equipment purchased under our $103.5 million
equipment facility with Cisco Systems Capital Corporation and as a result of
$10.0 million in increased indebtedness as a result of the Goldman Sachs
Credit Partners L.P. senior secured credit facility.

  Interest income decreased approximately $578,000 from the second quarter of
1998 to the second quarter of 1999 and increased $341,000 from the six months
ended June 30, 1998 to the six months ended June 30, 1999. The decline in
interest income for the second quarter comparison is a result of the decline
in cash, cash equivalents, short-term investments and restricted cash due to
our continued use of the proceeds from the offering of the 13% Senior Notes
for working capital requirements, capital expenditures, acquisitions and debt
payments. However the increase from the first six months of 1998 to the first
six months of 1999 is due to a full six months interest earned in 1999 on the
remaining proceeds from the $160.0 million in principal amount of our 13%
Senior Notes issued in April 1998 and interest earned on the proceeds from the
sale of convertible preferred stock in March 1999 compared to three months of
interest earned in 1998.

  Interest income will increase in the third quarter of 1999 due to the
temporary investment of the proceeds from our Initial Public Offering in July
1999, prior to their use in our business.

  Other income (expense), net which consists of miscellaneous other non-
operating types of income and expenses, decreased from net other income of
approximately $3,000 for the second quarter of 1998 to net other expense of
approximately $403,000 for the second quarter of 1999 and decreased from net
other income of approximately $13,000 for the six months ended June 30, 1998
to net other expense of approximately $311,000 for the six months ended June
30, 1999. This change is primarily due to a loss recognized on the termination
of a stock purchase agreement and sale of an investment.

Liquidity and Capital Resources

  Since inception, in addition to borrowing under our credit facilities we
have funded our net losses and capital expenditures through financing
activities as outlined in the following table. In the table below, net

  Our principal uses of cash are to fund working capital requirements, capital
expenditures, business acquisitions and operating losses. We expect that our
expansion will require additional capital expenditures and direct operating
costs and expenses. As a result, we expect to incur net losses for at least
the next 30 months. However, if our customer base grows and we are successful
in offering all of our data services and products, we believe revenue will
increase in a larger proportion to operating expenses.

  As of June 30, 1999, we had current assets of $78.9 million, including cash
and cash equivalents of $11.2 million, short-term investments of $8.0 million
and restricted cash of $20.8 million, and working capital of $17.5 million. In
addition, we also had $22.5 million in non-current restricted cash. The
majority of our restricted cash, along with the interest we earn on this cash,
will be used to make the interest payments through April 2001 on our 13%
Senior Notes. We invest excess funds in short-term investments until these
funds are needed for capital investments, acquisitions and operations of the
business.

  Cash Flows From Operating Activities: Operating activities used cash of
approximately $37.1 million during the six months ended June 30, 1999 and $8.8
million during the six months ended 1998. The majority of this increase was
due to a net loss of $43.1 million and a combined increase in trade accounts
receivable, inventory and prepaid and other current assets of approximately
$6.6 million, which were partially offset by non-cash expenses including
depreciation and amortization, stock compensation and amortization of
financing costs aggregating $10.5 million and a net increase in current
liabilities including trade accounts payable, accrued liabilities and deferred
revenue of $2.1 million. Cash used in operating activities for the first six
months of 1998 was primarily due to our net loss of $16.3 million and a
combined increase in current assets including trade accounts receivable and
inventory of $5.2 million, partially offset by an increase in accrued interest
of $5.2 million, increases to current liabilities of $4.3 million and non-cash
expenses aggregating 3.2 million.

  Cash Flows From Investing Activities: Investing activities used cash of $6.3
million during the six months ended June 30, 1999 and $140.7 million during
the six months ended June 30, 1998. Cash used in investing activities during
the first six months of 1999 primarily consisted of short-term investments of
$8.0 million, business combinations of $2.0 million, investment in leases of
$3.1 million and capital expenditures of $1.3 million. These investing
outflows were partially offset by $8.1 million provided from maturities in
restricted cash which were used to make interest payments. An additional $10.5
million of capital expenditures were financed under our financing facilities.
The large amount of cash used in investing activities during the first

six months of 1998 was a result of the investment of the proceeds from the
$160.0 million Senior Notes, $73.7 million of which was invested in short-term
investments, pending their use in our business and $56.8 million was invested
and is classified as restricted cash pending its use for interest payments on
the Senior Notes, two of which had been made as of June 30, 1999. In addition,
$2.7 million was classified as restricted cash as a result of the issuance of
letters of credit, $5.6 million was used for capital expenditures and
approximately $1.6 million was used for business combinations.

  Not reflected in investing activities is the acquisition of Choice
Solutions, Inc. (CSI) in July 1999. CSI was a provider of data network
integration services based in Dallas, Texas. The purchase price consisted of
$1.1 million in cash and 15,000 shares of our common stock. Additional shares
may be issued if certain financial objectives are met.

  Cash Flows From Financing Activities: Financing activities provided cash of
approximately $29.0 million during the first six months of 1999 and
approximately $153.1 million during the first six months of 1998. Cash
provided by financing activities during 1999 consisted of approximately $19.2
million in net proceeds from the sale of our convertible preferred stock, $9.5
million in net proceeds from borrowing under the senior secured credit
facility and $5.4 million in new proceeds from the exercise of options and
warrants, which was partially offset by approximately $5.1 million in payments
on long-term borrowings. Cash provided by financing activities during the
first six months of 1998 consisted of $154.2 million in net proceeds from the
sale of the $160.0 million Senior Notes, net of $1.3 million in payments on
long-term notes payable and capital leases.

  In November 1997, we entered into an agreement with Comdisco, Inc. through
which we can receive up to $50.0 million of equipment lease financing. At June
30, 1999, $30.0 million was available to us under this facility of which a
total of approximately $14.6 million had been utilized. This facility will
expire on June 30, 2000. The remaining $20.0 million will become available
upon the satisfaction of additional conditions.

  On April 2, 1998, we completed the offering of our 13% Senior Notes, in the
aggregate principal amount of $160.0 million and warrants to purchase 864,000
shares of common stock. At the closing, we deposited $56.8 million of the
proceeds from that offering in a collateral account. The amount in the
collateral account along with the interest earned will be sufficient to pay
the first six interest payments on the 13% Senior Notes, the second of which
was made on April 1, 1999. We received approximately $95.6 million after
deducting offering costs of approximately $7.6 million and funding the
collateral account. The 13% Senior Notes contain certain covenants that
restrict our ability to incur additional debt and make certain payments,
including dividends.

  In March 1999, we sold to affiliates of the Sandler Capital 800,000 shares
of Series A Convertible Preferred Stock and warrants to purchase 958,333
shares of our common stock, for total consideration of $20.0 million. The
warrants have an exercise price of $15.00 per share and are exercisable for
five years. The proceeds from the sale, net of related offering costs, were
approximately $19.2 million.

  In June 1999,we entered into a $10.0 million senior secured credit facility
with Goldman Sachs Credit Partners L.P. The proceeds of this facility will be
used for working capital and other general corporate purposes. We cannot re-
borrow amounts repaid under this facility. In connection with this facility,
we also issued to Goldman Sachs Credit Partners L.P. a warrant to acquire
375,000 shares of common stock at an exercise price of $15.00 per share. As of
June 30, 1999 we had borrowed the full amount under this facility.

  In July 1999, we entered into a six-year $103.5 million credit facility with
Cisco Systems Capital Corporation. This credit facility will provide the
financing for the purchase and installation of our Cisco Systems, Inc. multi-
service data and voice switching platform and for other Cisco equipment. Under
the terms of this

agreement, Cisco Systems, Inc. also received a warrant to purchase 575,000
shares of our common stock. The
warrant has an exercise price of $15.00 per share and is exercisable for three
years from the date of issuance. The facility will be available in three
tranches over a three year period with quarterly payments due over the three
years beginning one year from the availability of each tranche.

  In July 1999 we completed an initial public offering of our common stock in
which 9,660,000 shares, including 723,271 shares sold by selling shareholders,
were sold at an offering price of $15.00 per share. We received proceeds from
the offering of approximately $122.7 million, net of selling shareholders
proceeds ($10.8 million), underwriting discount ($10.1 million), and offering
expenses ($1.2 million).

  In addition, we have a financing agreement with Sun Financial Group, Inc. a
subsidiary of GATX Capital Corporation, that was used to finance our internal
capital needs under which $5.0 million was outstanding on June 30, 1999. We
also have an agreement with GE Capital Fleet Services for financing purchases
of company vehicles, $1.2 million was outstanding under this facility as of
June 30, 1999.

  Future Capital Requirements. We have significant debt in relation to our
equity. At June 30, 1999, we had $189.1 million in debt and $56.3 million in
shareholders' deficit, which includes paid-in capital of $47.3 million, but
excluded $19.2 million in convertible preferred stock classified outside of
shareholders' equity. Upon the completion of our Initial Public Offering in
July 1999, we received an additional $122.7 million of paid-in-capital from
the sale of common shares, net of underwriter's discount and other costs, and
$19.2 million in convertible preferred stock was converted to common stock.
Our business plan will continue to require a substantial amount of capital to
fund our expansion of existing and acquired markets. Our business plan
includes the following:

  .  deploying our multi-functional converged data and voice switching
     platform in all of our markets and leasing of our IP/ATM network
     connecting our switches;

  .  funding the purchase, installation and ownership of our Enterprise
     Network Services customers networks (which includes providing our
     customers with all necessary hardware, software, transmission facilities
     and management maintenance and monitoring);

  .  continuing to develop customer care and sales organizations;

  .  continuing to develop our operational support system; and

  .  funding operating losses and debt service requirements.

  In addition, we will continue to evaluate acquisitions and investments.
Completing additional acquisitions and investments could require us to spend a
portion of our cash, and compel us to raise additional capital sooner.

  We estimate that our existing funds at June 30, 1999, the proceeds from our
July initial public offering, our available borrowing and lease financing
capacity and the proceeds from the exercise of warrants in July will be
sufficient to meet our capital requirements for the foreseeable future. We
could, however, require additional capital sooner due to material shortfalls
in our operating and financial performance or if we are more aggressive in our
expansion than currently contemplated. We cannot be certain that we would be
successful in raising sufficient debt or equity capital to fund our operations
on a timely basis or on acceptable terms. If needed financing were not
available on acceptable terms, we could be compelled to alter our business
strategy, or delay or abandon some of our future plans or expenditures or fail
to make interest payments on our debt. Any of these events would have a
material adverse effect on our financial condition, results of operations and
liquidity.

               CONDITION AND RESULTS OF OPERATIONS--(Continued)


Impact of the Year 2000 Issue

  The year 2000 issue generally describes the various problems that may result
from the improper processing of dates and date-sensitive calculations by
computers and other equipment as a result of computer hardware and
software using two digits to identify the year in a date. Those computers and
software will need to be upgraded or replaced to accept four digit dates to
distinguish dates in the 21st century from dates in the 20th century. The
problem could result in system failures or miscalculations and cause
disruptions in operations including, among other things, the inability to
process transactions, send invoices, provide data and voice communications
services or engage in similar normal business activities.

  State of Readiness. We have created a task force (consisting of
representatives from our information technology, product management, sales and
marketing, finance and legal departments) that evaluates our internal and
external systems as they relate to year 2000 issues. We have reviewed our
critical internal systems, including our systems for customer billing,
customer service and financial reporting. We have obtained year 2000 readiness
certifications from most manufacturers and suppliers of our internal systems.
Any internal systems which were identified as having a potential problem have
already been replaced or are in the process of being replaced or modified.
Except for portions of two systems relating to order entry procedures which we
acquired in two of the acquisitions we made in the last year (Tie and KCI), we
believe that our internal systems are year 2000 ready. We are in the process
of upgrading the two systems based upon the manufacturer's recommendation,
which should be completed by the third quarter of 1999.

  We continue to assess internal non-information technology systems and
external systems, including systems used by manufacturers and suppliers of
computer equipment, software programs, telephone systems, data systems,
systems comprising our enterprise networks and equipment used to provide
services to our customers.

  To date, we have not identified any year 2000 issues with third-parties
which could have a material adverse effect on our business. We may identify a
significant internal or external year 2000 issue in the future which, if not
remediated in a timely manner, could have a material adverse effect on our
business, financial condition and results of operations.

  Costs. We have not incurred any significant costs in identifying year 2000
issues other than the opportunity cost of the time spent by our personnel. We
do not anticipate any significant further costs in identifying year 2000
issues. Programming costs associated with conforming the two non-ready systems
are estimated to be approximately $500,000. We have prepared contingency
plans, including manual order entry procedures and identification of potential
software modifications, in the event that there are delays in moving the
information from the non-ready systems to our year 2000 systems. Costs
associated with our contingency plans could include the hiring of additional
personnel to process orders and implement software modifications. The exact
amount of the costs associated with our contingency plans cannot be determined
at this time as a result of not knowing the number of additional personnel
that may need to be hired.

  Risks of Year 2000 Issues. Based on our assessments to date, we believe that
we will not experience any material disruption in internal systems or
information processing as a result of year 2000 issues. However, almost all of
our systems and products relating to our internal and external systems and
products are manufactured or supplied by third parties which are outside of
our control. Although we have taken steps that we believe should have
identiied potential year 2000 issues, if some or all of our internal or
external systems and products fail, or if any critical systems are overlooked
or are not year 2000 ready in a timely manner, there could be a material
adverse effect on our business, financial condition or results of operations.
In addition, if a critical provider of services, such as those providers
supplying electricity, water or other services, or a vendor or manufacturer
supplying products sold to our customers, experiences difficulties resulting
in disruption of services to us or the
sale of malfunctioning products to our customers, there could be a material
adverse effect on our business.

Potential risks include

  .  the disruption of utility services resulting in a closure of the
     affected facility for the duration of the disruption;

  .  the disruption of data or voice services we provide to our customers;

  .  the inability to process customer billing accurately or in a timely
     manner;

  .  the inability to provide accurate financial reporting to management,
     auditors, investors and others;

  .  litigation costs associated with potential suits from customers and
     investors; and

  .  delays in implementing other projects as a result of work by internal
     personnel on year 2000 issues.
