                  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. As of
September 30, 1999 seven of these intregated switching platforms had been
installed. 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 September 30, 1999 and our
available borrowing and lease financing capacity 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 September 30, 1999, statement of
shareholders' equity (deficit) for the nine months ended September 30, 1999 and
the consolidated statements of operations and comprehensive loss, and cash flows
for the three and nine months ended September 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.

     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.

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 20,000 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. CSI was a data network integration services provider
based in Dallas, Texas. The purchase price consisted of $1,125,000 in cash. Up
to an additional $225,000 in shares of our common stock may be issued if certain
financial conditions are met.

     Network Technologies Group. In September 1999, we purchased the majority of
the assets and assumed certain liabilities of Network Technologies Group
("NTG"). NTG was a data network integration services provider based in Miami,
Florida. The purchase price consisted of $675,000 in cash and $475,000 in shares
of our common stock. Up to an additional $500,000 in shares of our common stock
may be issued if certain financial conditions are met.

     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.

Allocation of consideration given during the nine months ended September 30,
1999 to the acquired assets is as follows:

4. CREDIT FACILITIES:

     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
are being 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, none of which had been exercised as of
September 30, 1999. We have obtained waivers for non-compliance with certain
financial covenants of this facility as of September 30, 1999. We have borrowed
the full amount available 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, none of which had been exercised as
of September 30, 1999. 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.

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 Capital 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 or September 30, 1999.

6. SHAREHOLDER'S EQUITY (DEFICIT):

     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 $122.4 million, net of selling
shareholders ($10.8 million), underwriting discount ($10.1 million), and
offering expenses ($1.6 million).

     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.

7. 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:

     Entre Business Technology Group. In October 1999, we acquired Video
Enterprises Corporation, d/b/a Entre Business Technology Group ("EBTG"). EBTG
was a data network integration services provider based in Atlanta, Georgia. The
purchase price consisted of $2.0 in cash, $2.1 million in shares of our common
stock, and assumed debt of approximately $2.6 million, resulting in total
consideration of $6.7 million. An additional $700,000 in shares of our common
stock may be issued if certain financial conditions are met.

               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 also offer 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
facilty 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 16 strategic acquisitions, through
which we have accelerated our growth into new markets and obtained employees who
are experienced in the products and services we offer. Acquiring business in new
markets that have been successful in either voice products and services or data
products and services has given us the opportunity to cross-market all of our
products and services, including Enterprise Network Services, to the existing
customers of the businesses we acquire.

     We began offering Enterprise Network Services in December 1997 and have now
entered into long-term Enterprise Network Service contracts with 47 customers.
We expect these contracts will provide us with approximately $36.4 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.

     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. However, we expect these expenses to
continue 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 $49.1 million of goodwill, net of amortization, on
September 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.

     The percentages shown in the following table with respect to revenue
represent revenue for each business segment as a percentage of total revenue.
Percentages with respect to cost of sales excluding depreciation and gross
margin before depreciation are of the revenue for the related segment.

Summary Quarterly Financial Data

     The table below presents unaudited quarterly statement of operations data
for each of the nine quarters through September 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 second and third
quarters of 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 seven
markets. The increases in amortization are due to the increase in goodwill and
other intangible assets resulting from the completion of 16 acquisitions through
September 30, 1999. We have also experienced increasing operating and net losses
every quarter. However, net loss has declined as a percentage of revenue from
90% for the third quarter of 1997 to 62% of revenue for the third quarter of
1999.

Results of Operations

     Revenue for the third quarter of 1999 was $20.1 million greater than
revenue for the third quarter of 1998 and revenue for the nine months ended
September 30, 1999 was $75.4 million greater than revenue for the nine months
ended September 30, 1998. The increase in revenue was primarily due to the
addition of 24 new markets as result of an acquisition during the third quarter
of 1998 and an additional three new markets and the expansion of new and
existing markets through four acquisitions between September 30, 1998 to
September 30, 1999. The increase in revenue was also largely due to our growing
operations and sales staff having pursued the cross selling opportunities
presented in new markets. 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 September 30, 1998 to 13 at
September 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 41% in services for the nine months ended September 30, 1998, to
44% for the nine months ended September 30, 1999. A significant factor in our
strategy to increase services is through our Enterprise Network Services
offering. As of September 30, 1999 we had 47 customers, representing $36.4
million in revenue over the terms of their contracts compared to 16 customers
and $13.8 million in contract term revenue as of September 30, 1998.

     Cost of sales excluding depreciation increased $12.2 million from the third
quarter of 1998 to the third quarter of 1999 and increased $46.1 million from
the nine months ended September 30, 1998 to the nine months ended September 30,
1999, while declining as a percentage of total revenue from 69% for the nine
months ended September 30, 1998 to 64% for the nine months and quarter ended
September 30, 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 third quarter of 1998 to 76%
for the third quarter of 1999 and from 80% for the first nine months of 1998 to
75% for the first nine 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
52% for the third quarter of 1998 to 46% for the third quarter of 1999 and 49%
for the first nine 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 our offering of professional services such as network and web,
design, maintenance and monitoring and Enterprise Network Services which have a
lower related cost.

     Selling, general and administrative expenses increased $16.4 million from
the third quarter of 1998 to the third quarter of 1999 and increased $53.3
million from the nine months ended September 30, 1998 to the nine months ended
September 30, 1999. This increase in selling, general and administrative
expenses is largely due to continued growth of the support services organization
required to support expanding field operations, which accounted for
approximately $12.5 million or 39% of total selling, general and administrative
expenses for the three months ended September 30, 1999 and $34.2 million or 41%
of total selling, general and administrative expenses for the nine months ended
September 30, 1999. However, selling, general and administrative expenses
declined as a percentage of revenue from 80% for the first nine months of 1998
to 74% for the first nine months of 1999. We expect selling, general and
administrative expenses 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 addition and expansion of new and existing markets;
     -     the completion of four acquisitions;
     -     an increase from 777 employees at September 30, 1998 to 1,380 at
           September 30, 1999.

     Depreciation and amortization expense increased approximately $2.2 million
from the third quarter of 1998 to the third quarter of 1999 and increased $7.2
million from the first nine months of 1998 to the first nine months of 1999.
These increases are a direct result of increases of $42.2 million in property,
network and equipment. In addition, goodwill increased $10.7 million as a result
of the acquisitions completed between September 30, 1998 and September 30, 1999
and other intangible assets increased $3.2 million. As of September 30, 1999 we
had $49.1 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 addition and expansion of new and existing markets;
     -     the development and deployment of seven of our multi-functional,
           integrated data and voice switching platforms;
     -     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 $1.0 million from the third
quarter of 1998 to the third quarter of 1999 and increased $7.2 million from the
nine months ended September 30, 1998 to the nine months ended September 30,
1999. The increase for the nine month periods is primarily a result of a full
nine months of interest expense in 1999 compared to six 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, increased indebtedness under our equipment financing facilities
with Comdisco and Sun Financial Group, Inc. for property, network and equipment
purchased for our networks both inside and outside our customers' premises and
also as a result of indebtedness under the Goldman Sachs Credit Partners L.P.
senior secured credit facility.

     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 Services and equipment purchased under our $103.5 million
equipment facility with Cisco Systems Capital Corporation.

     Interest income decreased approximately $631,000 from the third quarter of
1998 to the third quarter of 1999 and increased $972,000 from the nine months
ended June 30, 1998 to the nine months ended September 30, 1999. The decline in
interest income for the third 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. The increases in interest income are due to earnings on the remaining
proceeds from the $160.0 million in principal amount of our 13% Senior Notes
issued in April 1998, proceeds from the sale of convertible preferred stock in
March 1999, the $10.0 million credit facility entered into in June 1999 and net
proceeds of approximately $122.4 million from the initial public offering in
July, 1999.

     Other income (expense), net which consists of miscellaneous other non-
operating types of income and expenses, changed from net other expense of
approximately $78,000 for the third quarter of 1998 to net other income of
approximately $102,000 for the third quarter of 1999 and increased from net
other expense of approximately $65,000 for the nine months ended September 30,
1998 to net other expense of approximately $209,000 for the nine months ended
September 30, 1999. The increase in expense 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 proceeds equals the
gross proceeds of the offering less advisors' fees, underwriting discounts and
other expenses associated with the offering.

     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 27 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 September 30, 1999, we had current assets of $174.0 million,
including cash and cash equivalents of $57.6 million, short-term investments of
$46.1 million and restricted cash of $20.8 million, and working capital of
$106.1 million. In addition, we also had $27.3 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 $63.6 million during the nine months ended September 30, 1999 and
$12.3 million during the nine months ended 1998. The majority of this increase
was due to a net loss of $69.4 million and a combined increase in trade accounts
receivable, inventory and prepaid and other current assets of approximately
$17.9 million and a $3.4 million decrease in accounts payable, which were
partially offset by non-cash expenses including depreciation and amortization,
stock compensation and amortization of financing costs aggregating $17.4 million
and a net increase in current liabilities including accrued liabilities and
deferred revenue of $6.2 million. Cash used in operating activities for the
first nine months of 1998 was primarily due to our net loss of $31.6 million and
a combined increase in current assets including trade accounts receivable and
inventory of $12.5 million, partially offset by an increase in accrued interest
of $10.4 million, increases to current liabilities of $14.1 million and non-cash
expenses aggregating 7.4 million.

     Cash Flows From Investing Activities: Investing activities used cash of
$61.8 million during the nine months ended September 30, 1999 and $139.4 million
during the nine months ended September 30, 1998. Cash used in investing
activities during the first nine months of 1999 primarily consisted of short-
term investments of $46.1 million, capital expenditures of $11.8 million,
business combinations of $3.8 million and investment in leases of $3.2 million.
These

investing outflows were partially offset by a change in restricted cash of $3.3
million. An additional $22.7 million of capital expenditures have been or are
waiting to be financed under our financing facilities. The large amount of cash
used in investing activities during the first nine months of 1998 was a result
of the investment of the proceeds from the $160.0 million Senior Notes, $27.0
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 September 30, 1999. In addition, $9.6 million was classified as
restricted cash as a result of the issuance of letters of credit, $9.1 million
was used for capital expenditures and approximately $42.4 million was used for
business combinations, primarily the acquisition of the majority of the assets
of Tie Communications, Inc.

     Not reflected in investing activities is the acquisition of Entre Business
Technology Group (EBTG) in October 1999. EBTG was a provider of data network
integration services based in Atlanta, Georgia. The purchase price consisted of
$2.0 million in cash, $2.1 million in shares of our common stock and $2.6
million in assumed debt. Additional  shares may be issued if certain financial
objectives are met.

     Cash Flows From Financing Activities: Financing activities provided cash of
approximately $157.5 million during the first nine months of 1999 and
approximately $152.2 million during the first nine months of 1998. Cash provided
by financing activities during 1999 consisted of approximately $122.4 million in
net proceeds from our initial public offering, $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 $13.1 million in new
proceeds from the exercise of options and warrants, which was partially offset
by approximately $10.2 million in payments on long-term borrowings. Cash
provided by financing activities during the first nine months of 1998 consisted
of $152.9 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
September 30, 1999, $30.0 million was available to us under this facility of
which a total of approximately $14.8 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 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 are being
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. We have
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. As of September 30, 1999 nothing
had been borrowed under this facilty.

     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 $122.4 million, net of selling shareholders
proceeds ($10.8 million), underwriting discount ($10.1 million), and offering
expenses ($1.6 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 $4.8 million was outstanding on September 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
September 30, 1999.

     Future Capital Requirements. We have significant debt in relation to our
equity. At September 30, 1999, we had $190.4 million in debt and $70.2 million
in shareholders' equity, which includes paid-in capital of $200.1 million. 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:

     -    continued deployment of 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 September 30, 1999, our available
borrowing and lease financing 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.

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 modified. We have taken all steps that we believe are
necessary to ensure that our internal systems are year 2000 ready.

     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 non-ready systems were
approximately $300,000. We have prepared contingency plans, including manual
order entry procedures and identification of potential software modifications,
in the event that there are any unforeseen problems. 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 have taken
all steps that we believe are necessary to ensure 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.

(d)  Use of proceeds from initial public offering:

     Pursuant to our initial public offering of our common stock we issued
8,936,729 shares, excluding 723,271 shares sold by selling shareholders, on July
19, 1999. The offering closed on July 23, 1999. The shares were registered with
the Securities and Exchange Commission pursuant to a Registration Statement on
Form S-1 (No. 333-78483) which was declared effective on July 19, 1999. The
public offering was underwritten by a syndicate of underwriters led by Goldman
Sachs & Co., J.P. Morgan & Co., Warburg Dillon Read LLC and William Blair &
Company. After deducting discounts and commisions of $10.1 million and expenses
of $1.6 million, we received net proceeds of $122.4 million.

Through September 30, 1999 the proceeds have been applied as follows:

</TABLE>

The balance of the proceeds has been used for working capital purposes or
temporarily invested in short-term investments until used to meet anticipated
cash needs. The use of proceeds from the offering does not represent a material
change in the use of proceeds described in the Registration Statement. None of
the net proceeds of the offering were paid directly or indirectly to any of our
directors, officers or to persons owning 10 percent or more of any class of our
equity securities or of our affiliates.
