PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus.
Because it is a summary, it does not contain all of the information that you
should consider before participating in the exchange offer. You should read the
entire prospectus carefully, including the section entitled "Risk Factors" and
the financial statements and the related notes to those statements included in
this prospectus. Except as otherwise required by the context, references in
this prospectus to "we," "us," the "Issuer" or the "Company" refer to the
business of KMC Telecom Holdings, Inc. and all of its subsidiaries. The term
"you" refers to prospective investors in the exchange notes (as defined).

The Company

We are a facilities-based competitive local exchange carrier providing
telecommunications and data services in Tier III Markets (markets with a
population from 100,000 to 750,000). A facilities-based competitive local
exchange carrier is one which operates its own network, including switching
equipment and transmission lines, rather than one which intends to primarily
resell the services of other carriers. The markets in which we operate are
predominantly located in the Southeastern and Midwestern United States. We
target as customers business, government and institutional end-users, as well
as Internet service providers, long distance carriers and wireless service
providers. Our objective is to provide our customers with a complete solution
for their communications needs. We currently provide on-net local dial tone,
Internet access, ISDN (or integrated services digital network), long distance,
special access, private line and a variety of other advanced services and
features.

We currently operate in 23 Tier III Markets. We have constructed robust
fiber optic networks in each of our markets which we believe allow us to ensure
high quality services, facilitate the delivery of value-added and data
services, and effectively control our costs. We currently have Lucent
Technologies Series 5ESS(R)-type switches in commercial operation in all of our
23 existing markets. We also intend to install Lucent switches in any future
networks which we may build. Over time, we expect to transition the majority of
our customers to our own networks by means of either unbundled network elements
leased from the incumbent local exchange carrier (i.e., the established local
telephone company, such as Ameritech, Bell Atlantic, BellSouth, SBC or one of
the subsidiaries of GTE Corporation or Sprint Corporation) or direct
connections to our own networks.

Through September 30, 1999, we have invested $454.1 million in property,
plant and equipment. For 1998, our revenues totaled $22.4 million, comprised of
$14.2 million from resale of switched and dedicated services and $8.2 million
from on-net special access, private line and switched services. "On-net"
switched services includes both switched services provided through direct
connections to our own networks and switched services provided through
unbundled network elements leased from the incumbent local exchange carrier.
Resale of switched and dedicated services accounted for 63% of our revenues for
1998, 56% of our revenues for the first quarter of 1999, 40% of our revenues
for the second quarter of 1999 and 38% of our revenues for the third quarter of
1999. To date, we have completed construction of our backbone in each of our
networks as planned. Our major customers include: AT&T Corp., Boeing Inc.,
Comcast Cable Communications, Inc., Daimler Chrysler Corporation, Harris
Corporation, Intergraph Corp., MCI WorldCom, Inc., NASA, Sprint Corporation,
Time-Warner, Inc. and UUNet Technologies, Inc.

High-speed connectivity has become important to business due to the dramatic
increase in Internet usage and the proliferation of personal computer- and
Internet protocol-based applications. By leveraging customer relationships and
bundling service offerings, competitive local exchange carriers such as the
Company have begun to exploit a variety of high-growth, value-added data
services opportunities, including high-speed Internet access, BRI (or Basic
Rate ISDN), PRI (or Primary Rate ISDN), HDSL (or high bit-rate digital
subscriber line), LAN (or Local Area Network) and WAN (or Wide Area Network)
connectivity, managed network services, Virtual Private Networks, remote access
and e-commerce services. Data services represented approximately 7% of our
revenue for the first nine months of 1999. We expect this percentage to grow
over time. To take advantage

3
<PAGE>

of this opportunity, we intend to continue to aggressively market our current
data services offerings, such as ISDN, HDSL, Internet access, Local Area
Network-to-Local Area Network interconnect, and Wide Area Network services, and
to roll out new services such as port wholesale, frame relay and ATM (or
asynchronous transfer mode).

We believe that our success in meeting our revenue targets and in completing
our networks as planned has demonstrated that our strategy of building
comprehensive, cost-effective, facilities-based networks in Tier III cities is
compelling. We believe we are positioned to become the leading facilities-based
competitive local exchange carrier focused on Tier III markets. Accordingly, we
have determined to significantly expand our business by constructing networks
in 14 additional Tier III Markets by the end of the first half of 2000. To
finance these expansion plans, we will utilize proceeds from our recent private
placements of PIK Preferred Stock, approximately $250.0 million available for
this purpose under our $600.0 million vendor financing facility with Lucent
Technologies Inc. and proceeds of the offering of the original notes.

The following table presents information, as of September 30, 1999,
concerning our existing 23 networks and the 14 new networks on which
construction has begun or for which network engineering has been completed:

(1) Refers to the date on which testing is completed and the switch is first
available to carry customer traffic. Fiber optic networks typically become
commercially operational for non-switched traffic in the quarter before the
switch is available to carry customer traffic. The quarters presented for
new networks represent our estimate of the calendar quarters in which the
new networks will be commercially operational. We cannot assure you that
the new networks will be commercially operational when estimated.
(2) Represents (i) for existing networks, current owned operational route miles
and (ii) for new networks, the number of operational route miles currently
estimated to be owned and operational at the time the network becomes
commercially operational.
(3) Addressable by either unbundled network elements leased from the incumbent
local exchange carrier or by a direct connection to our own network. We
define a commercial building as one with greater than ten employees.
(4) Represents all active switched channels we provide to customers either by
resale via the incumbent local exchange carrier's network, by unbundled
network elements leased from the incumbent local exchange carrier, or by
direct connection to our own network.
(5) Represents all active dedicated DS-0, DS-1 and DS-3 circuits we provide to
customers expressed on a DS-0 basis.

Business Strategy

The following are the key elements of our business strategy:

5
<PAGE>

aerial deployment of fiber optic cable, which is less expensive than the buried
deployment required in many Tier I and Tier II Markets. We estimate that
approximately 70% of our fiber is deployed aerially.

Early to Market Advantage. We strive to be the first facilities-based
competitive local exchange carrier in a geographic area to actively market and
provide services. We believe that by effecting early entry into Tier III
Markets with a facilities-based strategy, we will be able to limit entry by
additional competitive local exchange carriers, although we can give no
assurance in this regard.

Comprehensive Fiber Networks. We build geographically extensive, full
service, facilities-based networks. We believe such networks provide
significant operating leverage, facilitate the capture of market share, and are
likely to deter other competitive local exchange carriers from attempting to
penetrate our markets due to the cost of constructing a competing network of
equal capability. In all of our 23 existing markets, we have completed our
backbone construction connecting the market's central business district with
outlying office parks, large institutions, the locations of long distance
carriers' transmission equipment and major incumbent local exchange carrier
central offices. We intend to continue to expand our existing networks in
response to anticipated customer demand.

Local Presence with Personalized Customer Service. We seek to capture and
retain customers through local, personalized sales, marketing and customer
service programs. To this end, we:

. establish sales offices in each market in which we operate a network,

. strive to recruit our city directors and sales staff from the local
market,

. rely principally on a face-to-face selling approach, and

. support our sales staff with locally based customer service and
technical support personnel.

We believe that our "Creative Solutions with a Hometown Touch"(TM) sales
approach is very important to customers in Tier III Markets, who do not
typically receive focused local sales contact or customer support from the
incumbent local exchange carrier.

Focus on Value-Added Data Services. We believe it is strategically important
to offer these services because:

. they provide for competitive differentiation,

. they present a substantial margin opportunity,

. as a facilities-based provider, we are able to offer these services
without significant marginal operating costs, and

. incumbent local exchange carriers have underinvested in facilities and
sales forces related to these services.

Low Cost Construction. It is our practice to use innovative "switch-in-a-
box" construction and deployment techniques for most of our networks. Using
these techniques, transmission, switching and power equipment are pre-installed
by Lucent under controlled factory conditions in portable, weatherproof, storm-
proof concrete buildings delivered to the Lucent facility by our contractor.
The completed buildings are then shipped to the appropriate city for final
installation, reducing costs, installation risks and time to market.

installation. We believe that this system will allow us to quickly address
customer concerns and provide us with a competitive advantage in customer
service and operations efficiency.

Experienced Management Team. Our senior management team includes individuals
with over 250 years of experience, collectively, in the telecommunications
industry. It is led by Harold N. Kamine, Chairman of the Board of Directors,
and Michael A. Sternberg, the Company's President and Chief Executive Officer.
Other members of the team include Roscoe C. Young II, Chief Operating Officer,
James D. Grenfell, Executive Vice President, Chief Financial Officer and
Secretary, James L. Barwick, Senior Vice President and Chief Technology
Officer, Tricia Breckenridge, Executive Vice President--Business Development
and Paul R. DiMarco, Vice President--Information Technology and Chief
Information Officer.

Recent Developments

Senior Notes Offering. On May 24, 1999, we issued the original notes in a
private offering. Approximately $104.1 million of the proceeds of the offering
were used to purchase a portfolio of U.S. government securities which were
pledged to secure the payment of the first six interest payments on the notes
(including the exchange notes). We will use the net proceeds of the offering,
along with other funds, to complete the 14 additional networks which we plan to
construct by the end of the first half of 2000.

Preferred Stock Placements. On February 4, 1999, we issued PIK Preferred
Stock and warrants to purchase common stock for aggregate gross proceeds of
$65.0 million to two purchasers. On April 30, 1999, we issued additional shares
of PIK Preferred Stock and warrants to purchase common stock to an additional
purchaser for aggregate gross proceeds of $35.0 million.

Lucent Facility. On February 4, 1999, our subsidiary which will own the 14
additional networks which we plan to construct by the end of the first half of
2000, entered into a secured vendor financing facility with Lucent Technologies
Inc. (the "Lucent Facility"). Under this Lucent Facility, our subsidiary will
be permitted to borrow, subject to certain conditions, up to an aggregate of
$600.0 million, primarily for the purchase from Lucent of switches and other
telecommunications equipment. Only $250.0 million is presently available under
this Lucent Facility.

Expanded Senior Debt Facility. On December 22, 1998, we refinanced and
expanded our $70.0 million senior credit facility with Newcourt Commercial
Finance Corporation to a $250.0 million facility. Under the refinanced and
expanded facility (the "Senior Secured Credit Facility"), which is with a group
of lenders led by Newcourt Commercial Finance Corporation, First Union National
Bank, General Electric Capital Corporation and Canadian Imperial Bank of
Commerce, our subsidiaries which own our initial 23 networks are permitted to
borrow up to an aggregate of $250.0 million, subject to certain conditions, for
the purchase of fiber optic cable, switches and other telecommunications
equipment and, once certain financial conditions are met, for working capital
and for other general corporate purposes.

The Company is a Delaware corporation. Our principal executive offices are
located at 1545 Route 206, Suite 300, Bedminster, New Jersey 07921 and our
telephone number at that location is (908) 470-2100.

Summary Of The Exchange Offer

The Exchange Offer.......... We are offering to exchange $275,000,000
aggregate principal amount of our exchange notes
for a like aggregate principal amount of our
original notes. In order to be exchanged, the
original notes must be properly tendered and
accepted. All outstanding original notes that are
validly tendered and not validly withdrawn will
be exchanged.

Resales of Exchange Notes... Based on certain no-action letters issued by the
staff of the Securities and Exchange Commission,
we believe that the exchange notes may be offered
for resale, resold and otherwise transferred by
you without compliance with the registration and
prospectus delivery provisions of the Securities
Act; provided, that:

. you are acquiring the exchange notes in the
ordinary course of your business;

. you are not participating, do not intend to
participate, and have no arrangement or
understanding with any person to participate,
in the distribution of the exchange notes; and

. you are not an affiliate of the Company or the
Guarantor, within the meaning of Rule 405
under the Securities Act of 1933.

If any of the foregoing are not true and you
transfer any exchange note without delivering a
prospectus meeting the requirements of the
Securities Act or without an exemption from such
requirements, you may incur liability under the
Securities Act. We do not and will not assume, or
indemnify you against, such liability.

Registration Rights......... The terms of a registration rights agreement
which we entered into with the placement agents
for the original notes grants you certain
exchange and registration rights with respect to
your original notes. This exchange offer is
intended to satisfy all of those rights and those
rights will terminate when the exchange offer is
completed. If you do not exchange your original
notes for exchange notes, you will no longer be
able to obligate us to register your original
notes under the Securities Act, except in the
limited circumstances provided under the
registration rights agreement. In addition, you

8
<PAGE>

will not be able to resell, offer to resell or
otherwise transfer your original notes unless
they are registered under the Securities Act, or
unless you resell, offer to resell or otherwise
transfer them under an exemption from the
registration requirements of, or in a transaction
not subject to, the Securities Act. Please refer
to the section in this prospectus entitled "Risk
Factors--A Failure to Participate in the Exchange
Offer May Have Adverse Consequences."

Expiration Date.............
The exchange offer will expire at 5:00 p.m., New
York City time, on December 30, 1999 unless we
decide to extend it.

Conditions to the Exchange The exchange offer is not subject to any
Offer...................... condition other than certain customary
conditions, including that:

. there is no change in laws and regulations
which would impair our ability to proceed with
the exchange offer,

. there is no change in the current
interpretation of the staff of the Securities
and Exchange Commission which permits resales
of the exchange notes,

. there is no stop order issued by the staff of
the Securities and Exchange Commission which
suspends the effectiveness of the registration
statement of which this prospectus is a part,

. there is no litigation which impairs our
ability to proceed with the exchange offer,

. we obtain all the governmental approvals we
deem necessary for the exchange offer, and

. there is no change, or development involving a
prospective change, in our business or
financial affairs which might materially
impair our ability to proceed with the
exchange offer.

Exchange Agent in connection with the exchange
offer.

Summary of the Terms of the Exchange Notes

Notes Offered............... $275,000,000 aggregate principal amount of
131/2% Senior Notes due 2009. The form and terms
of the exchange notes are the same as the form and
terms of the original notes, except that the
exchange notes will be registered under the
Securities Act and, therefore, will not bear
legends restricting their transfer and will not
be entitled to registration rights under the
registration rights agreement. The exchange notes
will evidence the same debt as the original notes
and both the original notes and the exchange
notes are governed by the same indenture.

Maturity.................... May 15, 2009.

Yield and Interest.......... The exchange notes will accrue interest at a rate
of 13 1/2% per year, payable semi-annually on
each May 15 and November 15, beginning November
15, 1999.

Security.................... We used a portion of the proceeds from the sale
of the original notes to purchase a portfolio of
U.S. government securities that has been

10
<PAGE>

pledged as security for the first six interest
payments on the original notes and the exchange
notes.

Optional Redemption......... We may redeem any of the original notes and the
exchange notes beginning May 15, 2004. The
initial redemption price is 106.750% of their
principal amount, plus accrued interest. The
redemption price will decline each year after
2004 and will reach 100% of their principal
amount, plus accrued interest, beginning on May
15, 2007.

In addition, before May 15, 2002, we may redeem
up to 35% of the aggregate principal amount of
the original notes and the exchange notes with
the proceeds of certain sales of our capital
stock at 113.5% of their principal amount, plus
accrued interest. We may make such redemption
only if, after the redemption, an amount equal to
at least 65% of the aggregate principal amount of
the notes originally issued remains outstanding
and only if notice of the redemption is given
within 60 days of the related sale of stock.

Change of Control........... Upon a change of control (as defined in the
section of this prospectus entitled "Description
of the Exchange Notes") we will be required to
make an offer to purchase all of your exchange
notes at a purchase price in cash equal to 101%
of the aggregate principal amount of the exchange
notes together with accrued and unpaid interest,
if any, to the date of repurchase. Please refer
to the section of this prospectus entitled
"Description of the Exchange Notes--Repurchase of
Notes Upon a Change of Control."

Ranking..................... The exchange notes will:

. be unsecured (except as described in
"Security" above) senior obligations of KMC
Telecom Holdings, Inc.,

. rank equally in right of payment with all
existing and future unsubordinated, unsecured
indebtedness of KMC Telecom Holdings, Inc.,
and

. be senior in right of payment to any future
subordinated indebtedness.

At September 30, 1999, KMC Telecom Holdings, Inc.
(on an unconsolidated basis) had $292.2 million
of indebtedness other than the original notes.
However, we are a holding company and the notes
will be effectively subordinated to all existing
and future indebtedness (including the Senior
Secured Credit Facility and the Lucent Facility)
and liabilities (including trade payables) of our
subsidiaries. As of September 30, 1999, our
subsidiaries had liabilities of $172.3 million,
including indebtedness of $125.0 million. In
addition, our subsidiaries had an additional
$375.0 million of borrowing capacity available
from lenders under their credit facilities,
subject to certain conditions.

Certain Covenants........... The indenture under which the exchange notes will
be issued contains covenants that, among other
things, restrict our ability and the ability of
certain of our subsidiaries to:

. incur additional indebtedness,

. create liens,

. engage in sale-leaseback transactions,

. pay dividends or make distributions in respect
of capital stock,

. make certain investments or certain other
restricted payments,

. sell assets,

. redeem capital stock,

. issue or sell stock of restricted
subsidiaries,

. enter into transactions with stockholders or
affiliates, or

. effect a consolidation or merger of KMC
Telecom Holdings.

These limitations are, however, subject to a
number of important qualifications and
exceptions.

Book Entry; Delivery and
Form....................... The exchange notes will be represented by one or
more permanent global securities in bearer form
deposited on behalf of The Depository Trust
Company and registered in the name of Cede & Co.,
its nominee. You will not receive exchange notes
in registered form unless one of the events
described in the section of this prospectus
entitled "Description of the Exchange Notes--Book
Entry; Delivery and Form" occurs. Instead,
beneficial interests in the exchange notes will
be shown on, and transfers of these will be
effected only through, records maintained by the
Depository Trust Company with respect to its
participants.

Trading..................... There has previously been only a limited
secondary market, and no public market, for the
original notes. The original notes are eligible
for trading in the Private Offerings, Resales and
Trading Through Automated Linkages (PORTAL)
market. There is no established trading market
for the exchange notes. We do not currently
intend to apply for listing of the exchange notes
on any national securities exchange or for
quotation through any automated quotation system.
Accordingly, there can be no assurance as to the
development of any market for, or for the
liquidity of any market that may develop for, the
exchange notes. See "Risk Factors--There Will Be
No Public Market for the Exchange Notes."

Risk Factors

You should consider carefully the information provided in the section in
this prospectus entitled "Risk Factors" beginning on page 15 and all the other
information provided to you in this prospectus in deciding whether to tender
your original notes in the exchange offer.

SUMMARY CONSOLIDATED FINANCIAL DATA

Our financial data for the years ended December 31, 1996, 1997 and 1998
presented below were derived from our audited consolidated financial
statements. Our financial data as of September 30, 1999 and for the nine months
ended September 30, 1998 and 1999 presented below were derived from our
unaudited consolidated financial statements. Although this data is unaudited,
in the opinion of our management it reflects all adjustments (consisting only
of normal recurring adjustments) necessary for a fair presentation of results
for interim periods. Operating results for interim periods are not necessarily
indicative of results to be expected for the full fiscal years. You should read
this information in conjunction with the sections of this prospectus entitled
"Selected Financial Data," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and in conjunction with the historical
financial statements and notes thereto included in the back of this prospectus.

(a) During the second quarter of 1999, the Company recorded a $4.3 million
charge to other expense in connection with an unfavorable arbitration
award. The net amount due under the terms of the award was paid in full in
June 1999.
(b) Assuming that (i) the private placements of the Company's PIK Preferred
Stock which occurred on February 4 and April 30, 1999, (ii) the December
1998 refinancing and expansion of the Senior Secured Credit Facility, (iii)
the establishment of the Lucent Facility, (iv) the offering of the Senior
Discount Notes which occurred on January 29, 1998 and (v) the offering of
the original notes which occurred on May 24, 1999, had all been consummated
on January 1, 1998, interest expense would have been $80.0 million for 1998
and $64.9 million for the nine months ended September 30, 1999 and
dividends and accretion on redeemable preferred stock would have been $37.4
million for 1998 and $45.5 million for the nine months ended September 30,
1999.
(c) Excludes capitalized interest of (i) $103,000 for 1996, (ii) $854,000 for
1997, (iii) $5.1 million for 1998 and (iv) $3.5 million for the nine months
ended September 30, 1999. During the construction of the Company's
networks, the interest costs related to construction expenditures are
capitalized.
(d) Adjusted EBITDA consists of earnings (loss) before net interest, income
taxes, depreciation and amortization charges, stock option compensation
expense (a non-cash charge) and other expense. EBITDA consists of earnings
(loss) before all of the foregoing items except stock option compensation
expense and other expense. These items are provided because they are
measures commonly used in the telecommunications industry. They are
presented to enhance an understanding of the Company's operating results
and they are not intended to represent cash flow or results of operations
in accordance with generally accepted accounting principles. Adjusted
EBITDA and EBITDA are not calculated under generally accepted accounting
principles and are not necessarily comparable to similarly titled measures
of other companies. For a presentation of cash flows calculated under
generally accepted accounting principles, see the Company's historical
financial statements contained in the back of this prospectus.
(e) The ratio of earnings to fixed charges is computed by dividing pretax
income from continuing operations before fixed charges (other than
capitalized interest) by fixed charges. Fixed charges consist of interest
charges, dividend obligations and amortization of debt expense and discount
or premium related to indebtedness, whether expensed or capitalized, and
that portion of rental expense the Company believes to be representative of
interest. Earnings were insufficient to cover fixed charges by $4.6 million
for 1996, $33.5 million for 1997, $81.9 million for 1998, $56.7 million for
the nine months ended September 30, 1998, and $155.7 million for the nine
months ended September 30, 1999. After giving pro forma effect to the
increase in interest expense resulting from the December 1998 refinancing
and expansion of the Senior Secured Credit Facility, the establishment of
the Lucent Facility, the Senior Discount Note offering and the offering of
the original notes as if they occurred on January 1, 1998, earnings would
have been insufficient to cover fixed charges by $132.1 million for 1998
and by $172.8 million for the nine months ended September 30, 1999.
(f) Represents amounts pledged to secure the first six payments of interest on
the notes.

RISK FACTORS

You should carefully consider the risks described below before
participating in the exchange offer. The risks and uncertainties described
below are not the only ones facing us. Additional risks and uncertainties not
presently known to us or that we currently deem immaterial may also impair our
business operations.

If any of the following risks actually occur, our business, financial
condition or results of operations could be materially adversely affected. In
such case, you may lose all or part of your investment.

A Failure to Participate in the Exchange Offer May Have Adverse Consequences

The original notes have not been registered under the Securities Act of
1933 or any state securities laws. As a result, the original notes may not be
offered, sold or otherwise transferred except in compliance with the
registration requirements of the Securities Act and any other applicable
securities laws, or pursuant to an exemption therefrom. Original notes that
bear legends restricting their transfer that are not exchanged will continue
to bear those legends. In addition, upon completion of the exchange offer, the
holders of original notes that are not exchanged will not be entitled to have
such original notes registered under the Securities Act, nor will they have
any similar rights, under the registration rights agreement. We currently do
not intend to register under the Securities Act any original notes which
remain outstanding after completion of the exchange offer.

To the extent that original notes are tendered and accepted in the exchange
offer, the principal amount of the outstanding original notes will be reduced
by the principal amount so tendered and exchanged and a holder's ability to
sell unexchanged original notes could be adversely affected. As a result the
liquidity of the market for unexchanged original notes could be adversely
affected upon completion of the exchange offer.

We Have Had a Limited Operating History and Have Incurred Substantial Negative
Gross Profits, Operating Losses, Negative Cash Flow and Negative Adjusted
EBITDA

We were formed in September 1997 as a holding company. The Company's
subsidiaries commenced material operations in 1996 and, as a result, we have
had only a limited operating history and limited revenues. We have only
recently completed the process of building many of our networks. Accordingly,
you will have limited historical financial information upon which to base your
evaluation of our business and an investment in the notes. You should consider
our prospects for financial and operational success in light of the risks,
expenses and difficulties frequently encountered by companies in their early
stage of development.

In connection with the construction of our networks we have incurred and
expect to continue to incur significant and increasing negative gross profits,
operating losses and negative adjusted EBITDA while we expand our business and
build our customer base. We can give no assurance that we will obtain an
adequate customer base for any of our services. Our negative gross profits,
operating losses and negative cash flow have increased each of the last four
years. For 1998, we had revenues of $22.4 million, gross profits of negative
$14.9 million, operating losses of $55.8 million and adjusted EBITDA of
negative $39.4 million. For 1998, cash used by operations was $33.6 million,
cash expended for investing purposes was $180.2 million, and cash provided by
financing activities was $219.4 million. On a pro forma basis giving effect to
the increase in interest expense resulting from the December 1998 refinancing
and expansion of the Senior Secured Credit Facility, the establishment of the
Lucent Facility, the Senior Discount Note offering and the offering of the
original notes as if they occurred on January 1, 1998, our free cash flow
(EBITDA minus capital expenditures and interest expense) for 1998 would have
been negative $288.3 million. See the section in this prospectus entitled
"Selected Financial Data" for information on the first nine months of 1999.

Our negative gross profits, operating losses, negative adjusted EBITDA,
cash used by operations and capital expenditures will increase as a result of
the continuation of our expansion strategy. We cannot assure you that we will
achieve or sustain profitability or generate positive EBITDA or at any time
have sufficient resources to meet our capital expenditure and working capital
requirements. We will need to significantly increase our revenues and cash
flows to meet our debt service obligations, including our obligations on the
notes.

15
<PAGE>

We Must Renegotiate Certain Financial Covenants in Certain of Our Credit
Facilities to Avoid Default

We obtained a waiver of compliance, for the quarter ended September 30,
1999, with certain financial covenants (related to revenue and EBITDA)
contained in the Senior Secured Credit Facility. In addition, the EBITDA
covenant was amended for the fourth quarter of 1999 to a level which we expect
to achieve.

We Have a Substantial Amount of Indebtedness, Significant Debt Service
Requirements and Refinancing Risks

At September 30, 1999, we had outstanding approximately $692.2 million of
indebtedness. The participating lenders in our Senior Secured Credit Facility
have agreed to provide certain of our subsidiaries with up to an aggregate of
$250.0 million of financing, subject to certain conditions. Lucent has agreed
to provide another one of our subsidiaries with up to an aggregate of $600.0
million of financing, subject to certain conditions, approximately $250.0
million of which is currently available. We are currently engaged in
discussions with the agents for the lenders under the Senior Secured Credit
Facility and with Lucent which contemplate certain changes in the Senior
Secured Credit Facility and the Lucent Facility. See "--We Must Renegotiate
Certain Financial Covenants in Certain of Our Credit Facilities to Avoid
Default". Although the net proceeds from the offering of the notes have
enhanced our liquidity and improved our financial flexibility in the near
term, our total indebtedness and interest expense have significantly increased
as a result of that offering.

Our substantial indebtedness could have important consequences to you. For
example, it could:

. increase the chance that we will not be able to make payments on the
notes,

. limit our ability to obtain additional financing in the future for
working capital, capital expenditures, debt service requirements or
other purposes,

. require us to dedicate a substantial portion of our cash flow from
operations to make payments on our indebtedness, thereby reducing the
funds available to us for other purposes, including working capital and
capital expenditures,

. limit our flexibility in planning for, or reacting to changes in, our
business or the industry in which we operate,

. make us more highly leveraged than many, if not all, of our competitors,
which could place us at a competitive disadvantage compared to those of
our competitors that are less leveraged, and

. increase our vulnerability in the event of a downturn in our business.

If we fail to meet our obligations there could be a default on our
indebtedness which would permit the holders of substantially all of our
indebtedness to accelerate the maturity thereof. In such event, we may not be
able to meet our obligations on the notes.

16
<PAGE>

In connection with the buildup of our networks and expansion of our
competitive local exchange carrier services, we have been experiencing
increasingly negative adjusted EBITDA and our earnings were insufficient to
cover fixed charges for 1996, 1997, 1998 and the nine months ended September
30, 1999. After giving pro forma effect to the increase in interest expense
resulting from the December 1998 refinancing and expansion of the Senior
Secured Credit Facility, the establishment of the Lucent Facility, the Senior
Discount Note offering and the offering of the original notes as if they
occurred on January 1, 1998, our earnings would have been insufficient to
cover fixed charges by $132.1 million for 1998 and by $172.8 million for the
nine months ended September 30, 1999. There can be no assurance that we will
be able to improve our earnings before fixed charges or adjusted EBITDA or
that we will be able to meet our debt service obligations.

During 1999 we also intend to investigate the technological and market
feasibility of serving Tier IV Markets near our Tier III Markets. As part of
this investigation we currently plan to construct fiber optic networks in two
Tier IV markets during 1999.

We cannot assure you that our cash flow from operations and capital
resources will be sufficient to repay the notes, the Senior Discount Notes,
the Senior Secured Credit Facility and the Lucent Facility in full or that a
substantial portion of our indebtedness will not need to be refinanced. The
Senior Discount Notes, the Senior Secured Credit Facility and the Lucent
Facility all mature prior to the notes and any additional indebtedness
incurred in the future may mature prior to the notes and may need to be
refinanced. We cannot assure you that we will be able to effect such
refinancings. Any of the foregoing risks could have a material adverse effect
on our business, financial condition and results of operations and our ability
to make payments on the notes.

Under the Senior Secured Credit Facility and the Lucent Facility, our
subsidiaries are required to meet certain financial tests at the end of each
quarter. Failure to comply with these tests could limit our subsidiaries'
ability to make further borrowings, or could result in a default under the
Senior Secured Credit Facility or the Lucent Facility, allowing the lenders to
accelerate the maturity of the loans made thereunder. We obtained a waiver of
compliance, for the quarter ended September 30, 1999, with certain financial
covenants (related to revenue and EBITDA) contained in the Senior Secured
Credit Facility. In addition, the EBITDA covenant was amended for the fourth
quarter of 1999 to a level which we expect to achieve. We are presently
engaged in discussions with Lucent and the agents for the lenders under the
Senior Secured Credit Facility which contemplate amendments to the financial
covenants in the Lucent Facility and the Senior Secured Credit Facility for
periods after the fourth quarter of 1999. We believe that these discussions
will lead to definitive agreements during the first quarter of 2000. If,
however, we are not successful in completing the negotiations as presently
contemplated, it is likely that we will fail to comply with one or more of the
covenants presently contained in those facilities for the quarter ended March
31, 2000. See "--We Must Renegotiate Certain Financial Covenants in Certain of
Our Credit Facilities to Avoid Default". We cannot assure you that our
subsidiaries will be able to comply with these covenants in the future. Any
failure by our subsidiaries to comply with these covenants could have a
material adverse effect on our business, financial condition and results of
operations and our ability to make payments on the notes.

Because We Are a Holding Company, We Will Be Reliant on Funds from Our
Subsidiaries to Repay Our Indebtedness and Our Subsidiaries' Creditors May
Have Priority on those Funds

We are a holding company whose sole material asset is the common stock of
our subsidiaries. We have pledged all of the common stock of our operating
subsidiaries that own our 23 existing networks to the lenders under the Senior
Secured Credit Facility. In addition, we have pledged all of the common stock
of our subsidiary that will own the 14 new networks currently planned for
completion by the end of the first half of 2000 to the lenders under the
Lucent Facility. Our operating subsidiaries, which currently own substantially
all of our operating assets, are directly liable to the lenders under the
Senior Secured Credit Facility and the Lucent Facility, but have no liability
to the holders of the notes. We also loaned or contributed a substantial
portion of the net proceeds from the Senior Discount Note offering and from
the offering of the notes to our operating subsidiaries.

We must rely upon dividends and other payments from our operating
subsidiaries to generate the funds necessary to meet our obligations,
including the payment of principal and interest on the notes. These
subsidiaries

17
<PAGE>

are legally distinct from us and have no obligation to pay amounts due with
respect to the notes or to make funds available for such payments, except to
the extent that they may be obliged to repay loans which we make to them. Our
operating subsidiaries will not guarantee the notes. The ability of our
operating subsidiaries to make such payments to us will be subject to, among
other things, the availability of funds, the terms of each operating
subsidiary's indebtedness and applicable state laws. In particular, the terms
of the operating subsidiaries' credit facilities prohibit them from paying
dividends and principal and interest on intercompany borrowings unless, among
other things, they are in compliance with certain financial covenants.
Accordingly, we cannot assure you that we will be able to obtain any funds
from our operating subsidiaries. The unconsolidated financial statements of
KMC Telecom Holdings (the obligor on the notes) are presented as a schedule to
the financial statements at the back of this prospectus.

Claims of creditors of our subsidiaries, including trade creditors, will
generally have priority as to the assets of such subsidiaries over the claims
of the Company and the holders of our indebtedness, including the notes.
Accordingly, the notes will be effectively subordinated to the liabilities
(including the Senior Secured Credit Facility, the Lucent Facility and trade
payables) of our subsidiaries. At September 30, 1999, our subsidiaries had
approximately $172.3 million of liabilities (excluding intercompany
liabilities), including $125.0 million of secured indebtedness. In addition,
our subsidiaries had an additional $125.0 million of borrowing capacity
available under the Senior Secured Credit Facility and an additional $250.0
million of borrowing capacity available under the Lucent Facility, subject to
certain conditions. We have unconditionally guaranteed the repayment of the
Senior Secured Credit Facility and a portion of the Lucent Facility.

The notes will be unsubordinated, unsecured indebtedness of the Company. At
September 30, 1999, we had, on a consolidated basis, an aggregate of
approximately $125.0 million of secured indebtedness. This indebtedness was
secured by a pledge of all of our stock in those of our operating subsidiaries
which own our 23 existing networks and substantially all of their assets. If
the lenders of this secured indebtedness foreclose on the collateral, the
holders of the secured indebtedness will be entitled to payment out of the
proceeds of their collateral prior to holders of the notes. In the event of
bankruptcy of the Company, holders of secured indebtedness will have a claim
on the assets of the Company prior to the claim of the holders of the notes.
In addition, if the collateral is insufficient to satisfy such secured
indebtedness, holders of the secured indebtedness would be entitled to share
pari passu with the notes and the Senior Discount Notes with respect to any of
our other assets. Assets remaining after satisfaction of the claims of holders
of secured indebtedness may not be sufficient to pay amounts due on any or all
of the notes and the Senior Discount Notes then outstanding.

Our Future Growth May Require Substantial Additional Capital

Our current plans for expansion of our existing networks, the development
of new networks, the further development of our products and services and the
continued funding of operating losses will require substantial additional cash
from outside sources. We currently anticipate that our capital expenditures
for 1999 will be approximately $350.5 million, of which $218.5 million was
spent during the nine months ended September 30, 1999. We also anticipate that
we will have substantial net losses to fund in 1999 and future years and that
our substantial cash requirements will continue into the foreseeable future.

We believe that the net proceeds of the offering of the notes, together
with our cash, investments held for future capital expenditures, borrowings
expected to be available under the Senior Secured Credit Facility, borrowings
expected to be available under the Lucent Facility (approximately $250.0
million of which is expected to be available to fund our current business
plan) and the net proceeds from the placements of our PIK Preferred Stock will
provide sufficient funds for us to expand our business as currently planned
and to fund our currently anticipated expenses through the completion of the
initial fiber optic backbone and installation of a switch in our 23 existing
networks and the 14 additional networks currently planned for completion by
the end of the first half of 2000. Thereafter, we will require additional
financing.

However, in the event that:

. our plans change,

18
<PAGE>

. the assumptions upon which our plans are based prove inaccurate,

. we expand or accelerate our business plan, or

. we determine to consummate acquisitions,

the foregoing sources of funds may prove to be insufficient to complete all
such networks, and we may require additional financing sooner than we
currently expect.

Additional sources of financing may include:

. public or private equity or debt financings,

. capitalized leases, and

. other financing arrangements.

Pursuant to certain provisions of our Series A and Series C Cumulative
Convertible Preferred Stock, and our Series E and Series F Senior Redeemable,
Exchangeable, PIK Preferred Stock, we may not increase the authorized number
of shares of our preferred stock or common stock without the consent of the
holders of two-thirds of the shares of those series. We currently have only
three million shares of common stock authorized.

We cannot assure you that additional financing will be available to us on
acceptable terms, within the limitations contained in our indebtedness, or at
all. Failure to obtain such additional financing could result in the delay or
abandonment of some or all of our development and expansion plans and
expenditures, which would have a material adverse effect on our business
prospects and our ability to make payments on the notes.

Our Industry is Extremely Competitive and Many of our Competitors Have Greater
Resources Than We Do.

The telecommunications industry is extremely competitive, particularly with
respect to price and service. We face competition in all of our markets.
Generally, our incumbent local exchange carrier competitor is one of the
Regional Bell Operating Companies, one of GTE Corporation's subsidiaries or
one of Sprint Corporation's subsidiaries. The incumbent local exchange
carriers:

. have long-standing relationships with their customers,

. have financial, technical and marketing resources substantially greater
than ours,

. have the potential to fund competitive services with revenues from a
variety of businesses, and

. currently benefit from certain existing regulations that favor the
incumbent local exchange carriers over us in certain respects.

We do not believe that Tier III Markets can profitably support more than
two competitors to the incumbent local exchange carrier. Accordingly, we
believe that once we have completed the construction of our network backbone
and the installation of our switch in a given market, potential new entrants
in that market are likely to seek to deploy their capital elsewhere. We will
generally continue to build in our markets after initial backbone construction
and switch installation. We expect that this demonstration of our commitment
to our markets will further deter new entrants.

However, it is likely that in several of our markets we will face
competition from two or more facilities-based competitive local exchange
carriers. After the investment and expense of establishing a network and
support services in a given market, the marginal cost of carrying an
additional call is negligible. Accordingly, in Tier III Markets where there
are three or more facilities-based competitive local exchange carriers, we
expect substantial price competition. We believe that such markets are likely
to be unprofitable for one or more operators.

19
<PAGE>

The competitive local exchange carrier competitors in our 23 existing
markets include, among others:

(1) Huntsville--Knology Holdings (an ITC DeltaCom subsidiary) currently
operates a facilities-based network and a switch. Knology acquired Cable
Alabama and is marketing residential service bundling cable-telephony
services. It resells BellSouth services. Knology reports a host digital switch
in Huntsville. ICI-Intermedia Communications has a franchise to provide
service and some fiber optic cable in the city, but no switch. ICI is
reselling frame relay via BellSouth lines. AT&T Local Services has a point of
interface switch.

(2) Baton Rouge--Adelphia Business Solutions (formerly Hyperion) has a
switch and a 96 route mile fiber network. EATEL has a switch and a small fiber
ring; their network is mostly digital. EATEL is a KMC customer. ITC DeltaCom
reports a switch, although as of October 1999 it was not active. ITC
DeltaCom's fiber network is leased. e.spire has a switch and a fiber network
consisting of 1.2 route miles. Adelphia, ITC DeltaCom and e.spire resell
BellSouth services. American MetroCom reports a switch and had plans to
construct a network in the first quarter of 1999, although, as of October
1999, American MetroCom had not applied for construction permits.

(3) Shreveport--AT&T Local Services has a switch. e.spire has a network
consisting of 2.5 route miles, but does not have a switch.

(4) Corpus Christi--e.spire has a 1 route mile network, but does not have a
switch. LOGIX has a fiber network under construction. ChoiceCom, a subsidiary
of ICG Communications, Inc., has a network consisting of a 4 route mile loop
and a switch. TCG (now AT&T Local Services) reports a switch. However, as of

Potential competitors include:

. microwave and satellite carriers,

. wireless telecommunications providers,

. cable television companies,

. utilities,

. Regional Bell Operating Companies seeking to operate outside their
current local service areas, and

. large long distance carriers, such as AT&T and MCI WorldCom, which have
begun to offer integrated local and long distance telecommunications
services.

AT&T, TCI and Teleport have also announced their intention to offer local
services.

Consolidation of telecommunications companies and the formation of
strategic alliances within the telecommunications industry, as well as the
development of new technologies, could also give rise to significant new
competitors to the Company. One of the primary purposes of the
Telecommunications Act of 1996 is to promote competition, particularly in
local markets. We believe that Tier III Markets will also see more agent and
distributor resale initiatives.

Recent regulatory initiatives allow competitive local exchange carriers
such as the Company to interconnect with incumbent local exchange carrier
facilities. This provides increased business opportunities for us. However,
these regulatory initiatives have been accompanied by increased pricing
flexibility for, and relaxation of regulatory oversight of, the incumbent
local exchange carriers. If the incumbent local exchange carriers engage in
increased volume and discount pricing practices or charge us increased fees
for interconnection to their networks, or if the incumbent local exchange
carriers delay implementation of our interconnection to their networks, our
business, financial condition and results of operations and our ability to
make payments on the notes could be adversely affected.

To the extent we interconnect with and use incumbent local exchange carrier
networks to serve our customers, we are dependent upon their technology and
capabilities. We will become increasingly dependent on interconnection with
incumbent local exchange carriers as switched services become a greater
percentage of our business. The Telecommunications Act imposes interconnection
obligations on incumbent local exchange carriers, but we cannot assure you
that we will be able to obtain the interconnections we require at desirable
rates, terms and conditions. In the event that we experience difficulties in
obtaining appropriate and reasonably priced service from the incumbent local
exchange carriers, our ability to serve our customers would be impaired.

23
<PAGE>

Both the long distance business and data transmission business are
extremely competitive. Prices in both businesses have declined significantly
in recent years and are expected to continue to decline. In the long distance
business we will face competition from large carriers such as AT&T, MCI
WorldCom and Sprint. We will rely on other carriers to provide transmission
and termination for our long distance traffic and therefore will be dependent
on such carriers.

We expect to experience declining prices and increasing price competition.
We cannot assure you that we will be able to achieve or maintain adequate
market share or revenue, or compete effectively, in any of our markets. Any of
the foregoing factors could have a material adverse effect on our business,
financial condition and results of operations and our ability to make payments
on the notes.

The Regional Bell Operating Companies Have Disputed the Entitlement of
Competitive Local Exchange Carriers to Reciprocal Compensation for Certain
Calls to Internet Service Providers

Every time a customer of a Regional Bell Operating Company calls an
Internet service provider that is one of our customers, we are entitled to
receive payment from the Regional Bell Operating Company. This payment is
called "reciprocal compensation." The Regional Bell Operating Companies object
to making reciprocal compensation payments and are seeking to have this
changed by legislation, regulation and litigation. The Regional Bell Operating
Companies have threatened to withhold, and in many cases have withheld,
reciprocal compensation for the transport and termination of such calls. We
recognized revenue of approximately $2.9 million, or 12.9% of our 1998
revenue, from incumbent local exchange carriers related to reciprocal
compensation. We recognized revenue of approximately $4.8 million, or 11.4% of
our revenue, related to these calls, for the nine months ended September 30,
1999. Payments of approximately $135,000 and $375,000 were received from the
incumbent local exchange carriers during 1998 and the nine months ended
September 30, 1999, respectively.

We determined to recognize this revenue because we concluded, based upon
all of the facts and circumstances available to us at the time, including
numerous state public service commission and state and federal court decisions
upholding competitive local exchange carriers' entitlement to reciprocal
compensation for such calls, that realization of those amounts was reasonably
assured. On October 13, 1999, however, the Louisiana Public Service Commission
ruled that local traffic to Internet service providers in Louisiana is not
eligible for reciprocal compensation. As a result of that ruling, we
determined that we could no longer conclude that realization of amounts
attributable to reciprocal compensation for termination of local calls to
Internet service providers in Louisiana was reasonably assured. Accordingly,
we recorded an adjustment to reduce revenue in the quarter ended September 30,
1999, which reversed all reciprocal compensation revenue previously recognized
related to Internet service provider traffic in Louisiana for the entire year
of 1998 and for the first nine months of 1999. The adjustment amounted to $4.4
million, of which $1.1 million relates to the year ended December 31, 1998 and
$3.3 million relates to the nine months ended September 30, 1999.

To date, 35 state commissions have ruled on this issue in the context of
state commission arbitration proceedings or enforcement proceedings with
respect to existing interconnection agreements. So far, 31 of the 35 state
commissions have determined that reciprocal compensation is owed for such
calls with one of those, Missouri, not requiring payment until the public
service commission sets rates. Several of these cases are presently on appeal.
We cannot predict the outcome of these appeals, or of additional pending
cases. If these

24
<PAGE>

calls were to be determined not to be local calls and not subject to access
charges, it could have an adverse effect on our business, financial condition
and results of operations and our ability to make payments on the notes.

Our management will continue to consider the circumstances surrounding this
dispute periodically in determining whether reserves against unpaid balances
are warranted. As of September 30, 1999, no reserves are considered necessary
by management.

Our interconnection agreements provide for reciprocal compensation. As
these expire, the incumbent local exchange carriers are expected to refuse to
execute new agreements that provide for reciprocal compensation. This is the
case for our interconnection agreement with BellSouth, which expired in
February, 1999. Upon termination of our interconnection agreements, if we
cannot agree on reciprocal compensation with the incumbent local exchange
carrier, the matter will be referred for arbitration. If new interconnection
agreements do not provide for reciprocal compensation, this could have a
material adverse effect on our business, financial condition and results of
operations and our ability to make payments on the notes.

There Are Significant Risks in Our Expansion Strategy and a Failure to Manage
Our Growth Effectively Could Adversely Affect Our Operations

We must achieve substantial growth in order to meet our payment obligations
under our indebtedness. Our networks have only recently become commercially
operational and we have only recently deployed switches in our networks. Our
success will depend, among other things, upon our ability to:

. assess potential markets,

. design and build fiber optic backbone routes that provide ready access
to a substantial customer base,

. achieve a sufficient customer base,

. install facilities,

. obtain required rights-of-way, building access and governmental permits,

. implement interconnection and collocation with the incumbent local
exchange carriers,

. obtain unbundled network elements from incumbent local exchange
carriers, and

. secure financing.

In addition, we may make additional acquisitions of existing businesses.
Acquisitions could divert our resources and management time and would require
integration with our management information, payroll and other systems, and
with our existing networks and service offerings.

We cannot assure you that any expansions of our networks will be completed
on schedule, at a commercially reasonable cost or within our specifications.

Our growth may place a significant strain on our financial, management and
operational resources. Our future performance will depend, in part, upon our
ability to:

. manage our growth effectively,

. monitor operations,

. control costs, and

. maintain effective quality control.

This will require us to continue to implement and improve our operating,
financial and accounting systems, to expand, train and manage our employee
base and to effectively manage the integration of acquired businesses.

If we fail to expand in accordance with our plans or to manage our growth,
there would be a material adverse effect on our business, financial condition
and results of operations. In addition, the establishment of

25
<PAGE>

new operations or acquisitions will involve significant expenses in advance of
anticipated revenues and may cause fluctuations in our operating results. Any
of the foregoing risks could have a material adverse effect on our ability to
make payments on the notes.

There Are Significant Risks Involved in Implementation of Our Business Plan

We are a recent entrant into the competitive local telecommunications
services industry. The local telecommunications services market was virtually
closed to competition until the Telecommunications Act of 1996 and related
regulatory rulings eliminated many barriers to entry. There are numerous
operating complexities associated with providing these services. We will be
required to develop new products, services and systems and will need to
develop new marketing initiatives to sell these services. We have limited
experience providing switched access and local dial tone services and we
cannot assure you that we will be able to successfully implement our switched
and data services strategy.

We are deploying high capacity digital switches in our markets. This will
enable us to offer local dial tone and a variety of switched access services
and data services. We expect to incur negative gross profits and negative
EBITDA from our switched services in any given market during the 24 to 36
month period after the switch is deployed. We expect operating margins to
improve as each network is expanded and larger volumes of traffic are carried
on our network. Implementation of our switched and data services is also
subject to the ability of our equipment manufacturers to meet our switch
deployment schedule. We cannot assure you that all of our switches will be
deployed on the schedule that we presently contemplate or that, if deployed,
our switches will be utilized to the degree that we presently expect.

Our services may not be profitable due to, among other factors:

. lack of customer demand,

. inability to secure access to incumbent local exchange carrier
facilities at acceptable rates,

. competition and pricing pressure from other competitive local exchange
carriers and the incumbent local exchange carriers, and

. cost overruns in connection with network build-outs.

The franchises that we obtain may require us to complete the build-out of
our network within a period specified in the franchise grant. If we are unable
to complete the build-out of a network within the specified period, and unable
to obtain an extension of time in which to complete the build-out, our
franchise agreement may be terminable by the local authority.

Any of the foregoing risks could have a material adverse effect on our
ability to make payments on the notes.

We Must Improve Our Customer Service Systems

Sophisticated information and processing systems are vital to our growth
and our ability to monitor costs, bill customers, provision customer orders
and achieve operating efficiencies. Until recently our billing and information
systems were produced largely in-house with partial reliance on third-party
vendors and these systems have generally met our needs due in part to our low
volume of bills and orders. As we expand our services and our customer base,
the need for sophisticated billing and information systems has increased
significantly. We have recently embarked upon a program to implement a full
suite of order management, customer service, billing and financial
applications. These applications will include electronic order tracking
software developed by Eftia OSS Solutions Inc., software providing
comprehensive billing functions developed by Billing Concepts Systems, Inc.,
and financial software developed by People Soft, Inc. Initial installation of
the new operational support systems was made during the third quarter of 1999,
with development and expansion to continue over the next 12 to 18 months. The
initial installation of the new billing and financial systems was completed
during the second quarter of 1999. Additional development of the billing and
financial systems will take place over the next 12 months. Our failure to:

26
<PAGE>

. implement the new operational support systems on a timely basis,

. adequately identify all of our information and processing needs, or

. upgrade our systems as necessary,

could have a material adverse effect on our business, financial condition and
results of operations and our ability to make payments on the notes.

We Will Be Reliant on Incumbent Local Exchange Carriers for Interconnection
and Provisioning

In each of our markets, we rely on incumbent local exchange carriers to
originate and terminate all of our switched services traffic until our own
switch becomes operational. Although the incumbent local exchange carriers are
legally required to "unbundle" their services and permit us to purchase only
the origination and termination services we need, thereby decreasing operating
expenses, we cannot assure you that such unbundling will be timely or result
in favorable prices. The Supreme Court overturned the Federal Communications
Commission's rules regarding what network elements must be unbundled by the
incumbent local exchange carriers, and remanded to the Federal Communications
Commission the question of which network elements are "necessary" to competing
carriers such as the Company. On November 5, 1999, the Federal Communications
Commission issued an order and proposed rulemaking establishing the network
elements that must be offered by incumbent local exchange carriers as
unbundled network elements. The Supreme Court's decision also creates some
uncertainty regarding the legal status of complaints filed at the Federal
Communications Commission to enforce interconnection agreements.

Carrying customer traffic on our own network generates substantially higher
margins than reselling (i.e. paying an incumbent local exchange carrier to
carry the traffic over its network). We are in the process of bringing our
customers on-net, so that their traffic will generate better margins. During
the first nine months of 1999 we significantly expanded our internal
department that deals with bringing customers on-net. During the next 12
months we expect to begin transmitting our orders to the incumbent local
exchange carriers electronically. However, we are dependent on the incumbent
local exchange carriers to carry out the conversion process. During 1998, the
first quarter of 1999, the second quarter of 1999 and the third quarter of
1999, respectively, 63%, 56%, 40% and 38% of our revenue was from reselling.

We cannot bring a customer on-net unless the incumbent local exchange
carrier sends a technician to physically alter its network. Historically, the
incumbent local exchange carriers have not stationed a large number of
technicians in Tier III Markets. We believe that incumbent local exchange
carriers are increasing their technical staffs in Tier III Markets, but they
are still not able to process our orders promptly.

In addition, the incumbent local exchange carriers have a financial
incentive to delay this process. Accordingly, we expect to face substantial
delays in bringing our resale customers on-net, which will delay our ability
to improve our financial results as much as we would like.

The foregoing factors could result in a material adverse effect on our
business, financial condition and results of operations and our ability to
make payments on the notes.

There Are Significant Risks of Entry into the Long Distance Business

In order to offer our end-user customers a complete package of
telecommunications services, we recently began to offer long distance
services. As a new entrant in the long distance business, we expect to
generate low gross margins and substantial start-up expenses as we roll out
our long distance service offerings.

Long distance telecommunications services will involve the origination of
traffic from end-user customers to our telecommunications switches. From
these, we will rely on other carriers to provide transmission and termination
services for our long distance traffic and will therefore be dependent on such
carriers. We enter into

27
<PAGE>

resale agreements with long distance carriers to provide us with long distance
transmission services. These agreements typically provide for the resale of
long distance services on a per minute basis (some with minimum volume
commitments or volume discounts). The negotiation of these agreements involves
estimates of future supply and demand for long distance telecommunications
transmission capacity, as well as estimates of the calling pattern and traffic
levels of our future long distance customers. Should we fail to meet our
minimum volume commitments, if any, pursuant to these resale agreements, we
may be obligated to pay underutilization charges or we may lose the benefit of
all or a portion of the volume discounts we have negotiated. Likewise, we may
underestimate our need for long distance facilities and therefore be required
to obtain the necessary transmission capacity in "spot markets" which are
often more expensive than longer term contracts. We cannot assure you that we
will acquire long distance capacity on favorable terms or that we can
accurately predict long distance prices and volumes so that we can generate
favorable gross margins from our long distance business. Our success in
entering into the long distance business will be dependent upon, among other
things:

. our ability to select new equipment and software and integrate these
into our networks,

. our ability to hire and train qualified personnel,

. our ability to enhance our billing, back-office and information systems
to accommodate long distance services, and

. the acceptance by potential customers of our long distance service
offerings.

If our long distance transmission business fails to generate favorable
gross margins, or if we fail in any of the foregoing respects, such failure
may have a material adverse effect on our business, financial condition and
results of operations and our ability to make payments on the notes.

There Are Significant Risks of Entry into the Data Transmission Business

To complement our telecommunications services offerings, we began offering
data transmission services in certain of our markets in 1997. We now offer
ISDN, HDSL, Internet access, Local Area Network-to-Local Area Network
interconnect and Wide-Area Network services and we are developing product
applications for port wholesale, frame relay and ATM services to complement
our existing data services. These services are primarily targeted at large and
medium sized businesses with substantial data communications requirements. In
providing these services, we will be dependent upon vendors for equipment, as
well as ongoing training and support and other matters. The success of our
entry into the data transmission business will be dependent upon, among other
things:

. our ability to select new equipment and software and integrate these
into our networks,

. our ability to hire and train qualified personnel,

. our ability to enhance our billing, back-office and information systems
to accommodate data transmission services, and

. the acceptance by potential customers of our service offerings.

We cannot assure you that we will be successful with respect to these
matters. If we are not successful with respect to these matters, there may be
a material adverse effect on our business, financial condition and results of
operations and our ability to make payments on the notes.

We Are Subject to Significant Government Regulation Which May Change in an
Adverse Manner

Our networks and the provision of switched and private line services are
subject to significant regulation at the federal, state and local levels. The
telecommunications industry in general, and the competitive local exchange
carrier industry in particular, are undergoing substantial regulatory change
and uncertainty. We cannot assure you that future regulatory, judicial or
legislative changes, or other regulatory activities, will not have a material
adverse effect on our business, financial condition and results of operations
and our ability to make payments on the notes. See "Business--Regulation".

28
<PAGE>

The Terms of Our Indebtedness May Restrict Our Corporate Activities

The documents under which our long-term debt was issued contain a number of
significant covenants. These covenants limit, among other things, our ability
to:

. borrow additional money,

. create liens,

. engage in sale-leaseback transactions,

. pay dividends,

. make investments,

. sell assets,

. issue capital stock,

. redeem capital stock,

. merge or consolidate, and

. enter into transactions with our stockholders and affiliates.

However, the limitations contained in the documents under which our long-
term debt was issued are subject to a number of important qualifications and
exceptions. In particular, while the indenture applicable to our Senior
Discount Notes and the indenture applicable to the notes restrict our ability
to incur additional indebtedness, they do permit us to incur an unlimited
amount of purchase money indebtedness. If we incur new indebtedness, the
related risks that we and our subsidiaries now face could intensify. Any of
the foregoing factors could have a material adverse effect on our business,
financial condition and results of operations and our ability to make payments
on the notes.

We Are Dependent on Agreements with Third Parties for Our Rights-of-Way and
Franchises

We must obtain easements, rights-of-way, entry to premises, franchises and
licenses from various private parties, actual and potential competitors and
state and local governments in order to construct and operate our networks,
some of which may be terminated upon 30 or 60 days' notice to us. We cannot
assure you that we will obtain rights-of-way and franchise agreements on
acceptable terms or that current or potential competitors will not obtain
similar rights-of-way and franchise agreements that will allow them to compete
against us. If any of our existing franchise or license agreements were
terminated or not renewed and we were forced to remove our fiber optic cables
or abandon our networks in place, such termination could have a material
adverse effect on our business, financial condition and results of operations
and our ability to make payments on the notes.

We Are Dependent on Certain Key Customers

Our five largest customers accounted for approximately 92% of our
consolidated revenues in 1996, 32% of our consolidated revenues in 1997, 11%
of our consolidated revenues in 1998 and 9% of our consolidated revenues in
the nine months ended September 30, 1999. We expect customer concentration to
continue to decrease as we expand into new markets and begin full scale
marketing of an integrated service package. In the near term, however, the
loss of, or decrease of business from, one or more of our principal customers
could have a material adverse effect on our business, financial condition and
results of operations, as well as our ability to make payments on the notes.
Although we actively market our products and services, we cannot assure you
that we will be able to attract new customers or retain our existing
customers.

We Could Experience System Failures and Service Disruptions As a Result of the
Year 2000 Problem

We face certain risks arising from Year 2000 issues which could have a
material adverse effect on our business and our ability to make payments on
the notes. See the section of this prospectus entitled "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Compliance" for a discussion of certain risks relating to Year 2000
issues.

The Telecommunications Industry is Subject to Rapid Technological Change

The telecommunications industry is subject to rapid and significant changes
in technology, and we must rely on third parties for the development of and
access to new technology. We cannot predict the effect of technological
changes on our business. We believe our future success will depend, in part,
on our ability to anticipate or adapt to such changes and to offer, on a
timely basis, services that meet customer demands. We cannot assure you that
we will be able to anticipate or adapt to such changes and to offer, on a
timely basis, services that meet customers' demands. A failure to do so would
have a material adverse effect on our business, financial condition and
results of operations and our ability to make payments on the notes.

The Future Success of Our Business Depends Upon Certain Key Personnel

We believe that the efforts of a small number of key management and
operating personnel will largely determine our success and the loss of any of
such persons could adversely affect the Company. We do not maintain so-called
"key man" insurance on any of our personnel. We have employment agreements
with Mr. Kamine, the Chairman of our Board of Directors, Mr. Sternberg, our
President and Chief Executive Officer, and Mr. Young, our Chief Operating
Officer, all of which currently run through December 31, 2002. Our success
will also depend in part upon our ability to hire and retain highly skilled
and qualified operating, marketing, financial and technical personnel. The
competition for qualified personnel in the telecommunications industry is
intense and, accordingly, we cannot assure you that we will be able to hire or
retain necessary personnel. Our failure to hire or retain necessary personnel
could have a material adverse effect on our business, financial condition and
results of operations, and our ability to make payments on the notes.

Control by Principal Stockholders

Harold N. Kamine, Chairman of the Board of the Company, presently owns
approximately 67.3% of the outstanding shares of our common stock. On a fully-
diluted basis, Nassau Capital Partners L.P. and certain of its affiliates and
Mr. Kamine own approximately 29% and 25% of the outstanding shares of common
stock, respectively. The Company, Mr. Kamine, Nassau, Newcourt Communications
Finance Corporation, a subsidiary of Newcourt Capital, Inc., General Electric
Capital Corporation, First Union National Bank and First Union Capital
Partners are parties to an Amended and Restated Stockholders Agreement, dated
as of October 31, 1997. Pursuant to provisions contained in both the Company's
certificate of incorporation and this stockholders agreement, Mr. Kamine and
Nassau are currently entitled to elect all of the Company's seven directors
with each entitled to nominate three directors, and the seventh to be
nominated by agreement of Mr. Kamine, Nassau and either Newcourt
Communications Finance Corporation or the holders of a majority of the
outstanding shares of our Series C Cumulative Convertible Preferred Stock. The
number of directors which Mr. Kamine is entitled to elect would be reduced to
two if the number of shares owned by him were to fall below two-thirds of the
number of shares of the Company initially issued to him, and to one if the
number of shares owned by him were to fall below one-third of the number of
shares initially issued to him. If his ownership were to fall below 5% of the
number of shares initially issued to him, Mr. Kamine would no longer be
entitled to elect any directors pursuant to such provisions. Comparable
reductions would be made to the number of directors which Nassau is entitled
to elect if its ownership were to fall below the specified levels. Certain
decisions concerning the operations or financial structure of the Company may
present conflicts of interest between Mr. Kamine and Nassau and the holders of
the notes. Pursuant to certain provisions of our Series A Cumulative
Convertible Preferred Stock, Series C Cumulative Convertible Preferred Stock
and Series E and Series F Senior Redeemable, Exchangeable

30
<PAGE>

PIK Preferred Stock, we may not increase the authorized number of shares of
preferred stock or common stock without the consent of the holders of two-
thirds of the shares of those series. We have only three million shares of
common stock authorized.

There Will Be No Public Market for the Exchange Notes

The original notes were not registered under the Securities Act or under
the securities laws of any state and may not be resold unless they are
subsequently registered or resold pursuant to an exemption from the
registration requirements of the Securities Act and applicable state
securities laws. The exchange notes will be registered under the Securities
Act but will constitute a new issue of securities with no established trading
market, and there can be no assurance as to:

. the development of any market for the exchange notes,

. the liquidity of any such market that may develop,

. the ability of holders of exchange notes to sell their exchange notes,
or

. the price at which the holders of the exchange notes would be able to
sell their exchange notes.

The original notes have been designated for trading among qualified
institutional investors in the PORTAL market. However, the exchange notes will
be new securities for which there is currently no public market. We do not
intend to list the exchange notes on any national securities exchange or for
quotation through any automated quotation system. We cannot assure you that an
active trading market will exist for the exchange notes, or that any trading
market that may develop will be liquid. If such a market were to exist, the
exchange notes could trade at prices that may be higher or lower than their
principal amount or purchase price, depending on many factors, including
prevailing interest rates, the market for similar notes and our financial
performance. If a market for the exchange notes does not develop, purchasers
may be unable to resell such exchange notes for an extended period of time, if
at all. Historically, the market for non-investment grade debt has been
subject to disruptions that have caused substantial volatility in the prices
of securities similar to the exchange notes. We cannot assure you that the
market for the exchange notes, if any, will not be subject to similar
disruptions. Any such disruptions may adversely affect you as a holder of the
exchange notes.

THE EXCHANGE OFFER

Purpose of the Exchange Offer

The original notes were initially issued and sold by KMC Telecom Holdings,
Inc. on May 24, 1999 to the placement agents pursuant to a placement agreement
dated May 19, 1999. The placement agents subsequently resold the original
notes to:

. qualified institutional buyers, as defined in Rule 144A under the
Securities Act of 1933, in reliance on Rule 144A; and

. non-U.S. persons in offshore transactions in reliance on Regulation S
under the Securities Act.

Pursuant to the placement agreement, KMC Telecom Holdings, Inc. and the
placement agents entered into a registration rights agreement. Pursuant to the
registration rights agreement, we agreed to use our best efforts to complete
the exchange offer on or before November 24, 1999.

The summary herein of certain provisions of the registration rights
agreement does not purport to be complete and we refer you to the provisions
of the registration rights agreement, which has been filed as an exhibit to
the registration statement of which this prospectus is a part.

The registration statement of which this prospectus is a part is intended
to satisfy our obligations with respect to the registration of original notes
in accordance with the terms of the registration rights agreement.

Following completion of the exchange offer, holders of original notes not
validly tendered in the exchange offer and holders of exchange notes will not
have any further registration rights. In addition, holders of original notes
will continue to be subject to restrictions on transfer of their original
notes. Accordingly, the liquidity of the market for original notes could be
adversely affected. See the section in this prospectus entitled "Risk
Factors--A Failure to Participate in the Exchange Offer May Have Adverse
Consequences."

Based on interpretations by the staff of the Securities and Exchange
Commission, as set forth in no-action letters issued to third parties, we
believe that the exchange notes issued pursuant to the exchange offer may be
offered for resale, resold or otherwise transferred by each holder of exchange
notes (other than a broker-dealer who acquires the notes directly from the
Company for resale pursuant to Rule 144A under the Securities Act or any other
available exemption under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act,
provided that such holder:

. is acquiring the exchange notes in the ordinary course of its business,

. is not participating in, and does not intend to participate in, a
distribution of the exchange notes within the meaning of the Securities
Act, and has no arrangement or understanding with any person to
participate in a distribution of the exchange notes within the meaning
of the Securities Act, and

. is not an affiliate (as defined in Rule 405 under the Securities Act) of
the Company.

By tendering original notes in exchange for exchange notes, each holder,
other than a broker-dealer, will be required to make representations to that
effect. If a holder of original notes is participating in or intends to
participate in, a distribution of the exchange notes, or has any arrangement
or understanding with any person to participate in a distribution of the
exchange notes to be acquired pursuant to the exchange offer, such holder may
be deemed to have received restricted securities and may not rely on the
applicable interpretations of the staff of the Securities and Exchange
Commission. Any such holder will have to comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
secondary resale transaction.

Each broker-dealer that receives exchange notes for its own account in
exchange for original notes may be deemed to be an "underwriter" within the
meaning of the Securities Act and must acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with
any resale of such exchange notes. The Letter of Transmittal which accompanies
this prospectus states that by so acknowledging

32
<PAGE>

and by delivering a prospectus, a broker-dealer will not be deemed to admit
that it is an "underwriter" within the meaning of the Securities Act. A
broker-dealer may utilize this prospectus, as it may be amended or
supplemented from time to time, in connection with offers to sell, resales and
other transfers of exchange notes received in exchange for original notes
which were acquired by such broker-dealer as a result of market making or
other trading activities. We have agreed that we will make this prospectus
available to any broker-dealer for a period of time not to exceed 180 days
after the consummation of the exchange offer for use in connection with any
such offer to sell, resale or other transfer. Please refer to the section in
this prospectus entitled "Plan of Distribution."

Terms Of the Exchange Offer

Upon the terms and conditions described in this prospectus and the
accompanying Letter of Transmittal, we will accept any and all original notes
which are validly tendered and which are not withdrawn prior to 5:00 p.m. New
York City time on December 30, 1999, or such later time and date to which we
extend the exchange offer in our sole discretion. This time and date, as
specified herein, or as extended, is referred to in this prospectus as the
"Expiration Date". We will issue $1,000 principal amount of exchange notes for
each $1,000 principal amount of original notes validly tendered pursuant to
the exchange offer and not withdrawn prior to the Expiration Date. Original
notes may only be tendered in integral multiples of $1,000.

The form and terms of the exchange notes are the same as the form and terms
of the original notes except that:

. the exchange notes will have been registered under the Securities Act
and, therefore, will not bear legends restricting their transfer, and

. the holders of the exchange notes will not be entitled to any of the
registration rights of holders of original notes under the registration
rights agreement, which rights, in any event, will terminate upon the
completion of the exchange offer.

The exchange notes will represent the same indebtedness as the original notes
and will be issued under, and be entitled to the benefits of, the indenture
which authorized the issuance of the original notes. The exchange notes and
the original notes will be treated as a single class of debt securities under
the indenture.

As of the date of this prospectus $275.0 million in aggregate principal
amount of original notes was outstanding. Only a registered holder of original
notes (or such holder's legal representative or attorney-in-fact), as
reflected in the Trustee's records under the indenture, may participate in the
exchange offer. There is no fixed record date for determining holders of the
original notes entitled to participate in the exchange offer. Holders of
original notes do not have any appraisal or dissenters' rights under the
General Corporation Law of Delaware or the indenture in connection with the
exchange offer. We intend to conduct the exchange offer in accordance with the
applicable provisions of the registration rights agreement and the applicable
requirements of the Securities Act and the rules and regulations of the
Securities and Exchange Commission thereunder.

We will be deemed to have accepted validly tendered original notes when,
and if, we give oral or written notice to the Chase Manhattan Bank, as
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of original notes for the purposes of receiving the exchange notes from us.

You will not be required to pay brokerage commissions or fees or, subject
to the instructions in the Letter of Transmittal, transfer taxes with respect
to the exchange of original notes in the exchange offer. We will pay all
charges and expenses, other than certain applicable taxes described below, in
connection with this exchange offer. See "--Fees and Expenses."

Extension; Amendments

In order to extend the exchange offer, we are obligated to notify the
Exchange Agent of any extension by oral (promptly confirmed in writing) or
written notice and will make a public announcement thereof, each prior to 9:00
a.m., New York City time, on the next business day after the previously
scheduled Expiration Date.

33
<PAGE>

We expressly reserve the right in our discretion:

. to delay accepting any original notes,

. to extend the exchange offer, or

. to amend the terms of the exchange offer in any manner,

by giving oral or written notice of such delay, extension or amendment to the
Exchange Agent.

If we amend the exchange offer in a manner determined by us to constitute a
material change, we will promptly disclose such amendment by means of a
prospectus supplement that we will distribute to each registered holder of
original notes. In addition, we will also extend the exchange offer for an
additional five to ten business days, depending on the significance of the
amendment, if the exchange offer would otherwise expire during such period.

Without limiting the manner in which we may choose to make a public
announcement of any delay, extension or amendment of the exchange offer, we
will have no obligation to publish, advertise or otherwise communicate any
such public announcement, other than by making a timely release to an
appropriate news agency.

Procedures For Tendering

Only a registered holder of original notes (or such registered holder's
legal representative or attorney-in-fact) may tender such original notes in
the exchange offer. The term "holder" with respect to the exchange offer means
any person in whose name original notes are registered on our books or any
other person who has obtained a properly completed bond power from the
registered holder. To tender your original notes in the exchange offer, you
must complete, sign and date the Letter of Transmittal, or a facsimile
thereof, have the signatures thereon guaranteed if required by the Letter of
Transmittal, and mail or otherwise deliver the Letter of Transmittal or such
facsimile together with the certificates representing the original notes being
tendered and any other required documents to the Exchange Agent at the address
set forth below under "--Exchange Agent" for receipt at or prior to 5:00 p.m.
New York City time on the Expiration Date. Alternatively, you may either:

. send a timely confirmation of a book-entry transfer (a "Book-Entry
Confirmation") of such original notes, if such procedure is available,
into the Exchange Agent's account at the Depository Trust Company ("DTC"
or the "depository") pursuant to the procedure for book-entry transfer
described below, at or prior to 5:00 p.m. on the Expiration Date, or

. comply with the guaranteed delivery procedures described below.

Your tender of original notes will constitute an agreement between you and
us in accordance with the terms and subject to the conditions set forth in
this prospectus and in the Letter of Transmittal.

THE METHOD OF DELIVERY OF ORIGINAL NOTES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT YOUR ELECTION AND RISK. INSTEAD OF DELIVERY BY
MAIL, WE RECOMMEND THAT YOU USE AN OVERNIGHT OR HAND DELIVERY SERVICE,
PROPERLY INSURED. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO ASSURE
TIMELY DELIVERY. YOU SHOULD NOT SEND THE LETTER OF TRANSMITTAL OR ANY ORIGINAL
NOTES TO THE COMPANY. YOU MAY REQUEST YOUR BROKERS, DEALERS, COMMERCIAL BANKS,
TRUST COMPANIES OR NOMINEES TO EFFECT SUCH TENDER ON YOUR BEHALF.

If you are the beneficial owner of original notes that are registered in
the name of a broker, dealer, commercial bank, trust company or other nominee
and you wish to tender your original notes, you should contact the registered
holder promptly and instruct such registered holder to tender on your behalf.
If you wish to tender on your own behalf, you must, prior to completing and
executing the Letter of Transmittal and delivering your

34
<PAGE>

original notes, either make appropriate arrangements to register ownership of
the original notes in your name or obtain a properly completed bond power from
the registered holder. The transfer of registered ownership may take
considerable time.

Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined below)
unless the original notes are tendered:

. by a registered holder who has not completed the box titled "Special
Delivery Instructions" on the Letter of Transmittal, or

. for the account of an Eligible Institution.

In the event that signatures on a Letter of Transmittal or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantee
must be made by a member firm of a registered national securities exchange or
of the National Association of Securities Dealers, Inc., a commercial bank or
trust company having an office or correspondent in the United States or an
"eligible guarantor institution" (within the meaning of Rule 17Ad-15 under the
Securities Exchange Act of 1934) that is a member of one of the recognized
signature guarantee programs identified in the Letter of Transmittal (an
"Eligible Institution").

If the Letter of Transmittal is signed by a person other than the
registered holder of any original notes listed therein, those original notes
must be endorsed or accompanied by a properly completed bond power, signed by
the registered holder exactly as the registered holder's name appears on the
original notes.

If the Letter of Transmittal or any original notes are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, those
persons should so indicate when signing. Unless waived by us, evidence
satisfactory to us of their authority to so act must also be submitted with
the Letter of Transmittal.

The Exchange Agent and the depository have confirmed that any financial
institution that is a participant in the depository's system may utilize the
depository's Automated Tender Offer Program to tender original notes.

A tender will be deemed to have been received as of the date when the
tendering holder's duly signed Letter of Transmittal accompanied by the
original notes being tendered (or a timely confirmation is received of a book-
entry transfer of original notes into the Exchange Agent's account at the
depository with an Agent's Message) or a Notice of Guaranteed Delivery from an
Eligible Institution is received by the Exchange Agent. Issuances of exchange
notes in exchange for original notes tendered pursuant to a Notice of
Guaranteed Delivery by an Eligible Institution will be made only against
delivery of the Letter of Transmittal (and any other required documents) and
the tendered original notes (or a timely confirmation is received of a book-
entry transfer of original notes into the Exchange Agent's account at the
depository with an Agent's Message, as defined below under "--Book-Entry
Transfer") to the Exchange Agent.

All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered original notes will be
determined by us in our sole discretion, which determination will be final and
binding. We reserve the absolute right to reject any and all original notes
not properly tendered or any original notes which if accepted, in our opinion
or in our counsel's opinion, would be unlawful. We also reserve the right to
waive any defects, irregularities or conditions of tender as to particular
original notes. Our interpretation of the terms and conditions of the exchange
offer (including the instructions in the Letter of Transmittal) will be final
and binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of original notes must be cured within such time as we
determine. Although we intend to notify you of defects or irregularities with
respect to tenders of original notes, neither we, the Exchange Agent nor any
other person shall incur any liability for failure to give such notification.
Tenders of original notes will not be deemed to have been made until such
defects or irregularities have been cured or waived.

35
<PAGE>

While we presently have no plan to acquire any original notes that are not
tendered in the exchange offer, or to file a registration statement to permit
resales of any original notes that are not tendered pursuant to the exchange
offer, we reserve the right in our sole discretion to purchase or make offers
for any original notes that remain outstanding subsequent to the Expiration
Date and, to the extent permitted by applicable law, purchase original notes
in the open market, in privately negotiated transactions or otherwise. The
terms of any such purchases or offers could differ from the terms of the
exchange offer.

Acceptance of Original Notes For Exchange; Delivery of Exchange Notes

Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will accept, promptly after the Expiration Date, all original notes
properly tendered and will issue the exchange notes promptly after acceptance
of the original notes. For purposes of the exchange offer, the original notes
will be deemed to have been accepted as validly tendered for exchange when,
and if, we have given oral or written notice to the Exchange Agent.

Return Of Original Notes

If any tendered original notes are not accepted for any reason set forth in
the terms and conditions of the exchange offer or if original notes are
withdrawn, we will return the unaccepted, withdrawn or non-exchanged original
notes to you without expense (or, in the case of original notes tendered by
book-entry transfer into the Exchange Agent's account at the depository
pursuant to the book-entry transfer procedures described below, the original
notes will be credited to an account maintained with the depository) as
promptly as practicable after withdrawal, rejection of tender, the Expiration
Date or earlier termination of the exchange offer.

Book-Entry Transfer

The Exchange Agent will make a request to establish an account with respect
to the original notes with the depository for purposes of the exchange offer
promptly after the date of this prospectus. Any financial institution that is
a participant in the depository's Book-Entry Transfer Facility system may make
book-entry delivery of the original notes by causing the depository to
transfer such original notes into the Exchange Agent's account and to deliver
an "Agent's Message" (as defined below) on or prior to the Expiration Date in
accordance with the depository's procedures for such transfer and delivery. If
delivery of original notes is effected through book-entry transfer into the
Exchange Agent's account at the depository and an Agent's Message is not
delivered, the Letter of Transmittal (or facsimile thereof), with any required
signature guarantees and any other required documents must be transmitted to
and received or confirmed by the Exchange Agent at its addresses set forth
herein under "--Exchange Agent" prior to 5:00 p.m., New York City time on the
Expiration Date or pursuant to the guaranteed delivery procedures described
below. DELIVERY OF DOCUMENTS TO THE DEPOSITORY DOES NOT CONSTITUTE DELIVERY TO
THE EXCHANGE AGENT. All references in this prospectus to deposit of original
notes will be deemed to include the depository's book-entry delivery method.

The term "Agent's Message" means a message transmitted by the depository to
and received by the Exchange Agent and forming a part of a Book-Entry
Confirmation which states that the depository has received an express
acknowledgment from the tendering participant, which acknowledgment states
that the participant has received and agrees to be bound by, and makes the
representations and warranties contained in the Letter of Transmittal and that
we may enforce the Letter of Transmittal against the participant.

Guaranteed Delivery Procedures

If you are a registered holder of original notes and wish to tender your
original notes, but time will not permit your required documents to reach the
Exchange Agent on or prior to the Expiration Date, you may still tender in the
exchange offer if:

. you tender through an Eligible Institution,

36
<PAGE>

. on or prior to the Expiration Date, the Exchange Agent receives from
such Eligible Institution a properly completed and duly executed Letter
of Transmittal and Notice of Guaranteed Delivery, substantially in the
form provided by us (by facsimile transmission, mail or hand delivery),
setting forth your name and address as holder of original notes and the
amount of original notes tendered, stating that the tender is being made
thereby and guaranteeing that within five business days after the
Expiration Date, a Book-Entry Confirmation or the certificates relating
to the original notes, and all other documents required by the Letter of
Transmittal will be deposited by the Eligible Institution with the
Exchange Agent, and

. a Book-Entry Confirmation or the certificates for all tendered original
notes, and all other documents required by the Letter of Transmittal are
received by the Exchange Agent within five business days after the
Expiration Date.

Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their original notes according to the
guaranteed delivery procedures set forth above.

Withdrawal Of Tenders

Except as otherwise provided in this prospectus, you may withdraw tenders
of original notes any time prior to 5:00 p.m., New York City time, on the
Expiration Date.

For a withdrawal to be effective, you must send a written notice of
withdrawal to the Exchange Agent at the address set forth below under "--
Exchange Agent" prior to 5:00 p.m., New York City time, on the Expiration
Date. Any such notice of withdrawal must:

. specify the name of the person having deposited the original notes to be
withdrawn,

. identify the original notes to be withdrawn (including the certificate
number or numbers and principal amount of original notes), and

. be signed by the holder in the same manner as the original signature on
the Letter of Transmittal by which the original notes were tendered
(including required signature guarantees).

All questions as to the validity, form and eligibility (including time of
receipt) of notices of withdrawal will be determined by us, in our sole
discretion, and our determination will be final and binding on all parties.
Any original notes so withdrawn will be deemed not to have been validly
tendered for exchange for purposes of the exchange offer, and no exchange
notes will be issued with respect thereto unless the original notes so
withdrawn are validly retendered. Properly withdrawn original notes may be
retendered by following one of the procedures described above at any time on
or prior to the Expiration Date.

Termination of Certain Rights

All registration rights under the registration rights agreement accorded to
holders of the original notes (and all rights to receive additional interest
on the notes to the extent and in the circumstances specified therein) will
terminate upon consummation of the exchange offer except with respect to our
duty to keep the registration statement effective until the closing of the
exchange offer and, for a period of 180 days after the closing of the exchange
offer, to provide copies of the latest version of the prospectus to any
broker-dealer that requests copies of such prospectus in the Letter of
Transmittal for use in connection with any resale by such broker-dealer of
exchange notes received for its own account pursuant to the exchange offer in
exchange for original notes acquired for its own account as a result of
market-making or other trading activities.

37
<PAGE>

Conditions of the Exchange Offer

Notwithstanding any other term of the exchange offer, we will not be
required to accept original notes for exchange, or issue exchange notes in
exchange for any original notes, and we may terminate or amend the exchange
offer as provided in this prospectus before the acceptance of such original
notes, if:

. a change in laws or regulations occurs which, in our sole judgment,
impairs our ability to proceed with the exchange offer,

. a change in the current interpretation of the staff of the Securities
and Exchange Commission occurs which current interpretation permits the
exchange notes issued pursuant to the exchange offer in exchange for the
original notes to be offered for resale, resold or otherwise transferred
by holders thereof (other than in certain circumstances),

. a stop order is issued by the Securities and Exchange Commission or any
state securities authority suspending the effectiveness of the
registration statement of which this prospectus is a part or the
qualification of the indenture under the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"), or proceedings are initiated or, to
our knowledge, threatened for that purpose,

. an action or proceeding is instituted or threatened in any court or
before any governmental agency or body that in our judgment would
reasonably be expected to prohibit, prevent or otherwise impair our
ability to proceed with the exchange offer,

. a governmental approval is not obtained, which approval we deem, in our
sole judgment, necessary for the consummation of the exchange offer, or

. a change, or a development involving a prospective change, in our
business or financial affairs occurs which, in our sole judgment, might
materially impair our ability to proceed with the exchange offer.

These conditions are for our sole benefit and we may assert them regardless
of the circumstances giving rise to any such condition or we may waive them,
in whole or in part, at any time and from time to time, if we determine in our
reasonable judgment that any of the foregoing events or conditions has
occurred or exists or has not been satisfied, subject to applicable law. Our
failure at any time to exercise any of the foregoing rights will not be deemed
a waiver of any such right and each such right will be deemed an ongoing right
which we may assert at any time and from time to time.

If we determine that we may terminate the exchange offer, as provided
above, we may:

. refuse to accept any original notes and return to the holders thereof
any original notes that have been tendered,

. extend the exchange offer and retain all original notes tendered prior
to the Expiration Date, subject to the rights of holders of tendered
original notes to withdraw their tendered original notes, or

. waive such termination event with respect to the exchange offer and
accept all properly tendered original notes that have not been withdrawn
or otherwise amend the terms of the exchange offer in any respect as
provided under the section in this prospectus entitled "--Extension;
Amendments."

The exchange offer is not conditioned upon any minimum principal amount of
original notes being tendered for exchange.

We have no obligation to, and will not knowingly, permit acceptance of
tenders of original notes from our affiliates (within the meaning of Rule 405
under the Securities Act) or from any other holder or holders who are not
eligible to participate in the exchange offer under applicable law or
interpretations thereof by the Securities and Exchange Commission, or if the
exchange notes to be received by such holder or holders of original notes in
the exchange offer, upon receipt, will not be tradable by such holder without
restriction under the Securities Act and the Securities Exchange Act of 1934
and without material restrictions under the "blue sky" or securities laws of
substantially all of the states of the United States.

Exchange Agent

We have appointed The Chase Manhattan Bank as Exchange Agent for the
exchange offer. Questions and requests for assistance, requests for additional
copies of this prospectus or of the Letter of Transmittal and requests for
Notices of Guaranteed Delivery should be directed to the Exchange Agent as
follows:

By registered or certified mail, by overnight courier or by hand:

The Chase Manhattan Bank

Room 234, North Building
New York, New York 10041
Attention: Carlos Esteves

By facsimile Transmission:

The Chase Manhattan Bank
Facsimile Number: (212) 638-7380 or (212) 638-7381
Confirm by Telephone: (212) 638-0828

In addition, Letters of Transmittal and any other required documentation
should be sent to the Exchange Agent at the address set forth above, except
where facsimile transmission is specifically authorized (e.g., withdrawals and
Notices of Guaranteed Delivery). DELIVERY OF THE LETTER OF TRANSMITTAL TO AN
ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION VIA FACSIMILE OTHER THAN
AS SET FORTH ABOVE WILL NOT CONSTITUTE A VALID DELIVERY.

Fees And Expenses

We will bear the expenses of soliciting tenders pursuant to the exchange
offer. The principal solicitation is being made by mail; however, additional
solicitation may be made by telegraph, facsimile transmission, telephone or in
person by officers and regular employees of KMC Telecom Holdings and its
affiliates.

We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to brokers, dealers or others soliciting
acceptance of the exchange offer. We will, however, pay the Exchange Agent
reasonable and customary fees for its services and will reimburse its
reasonable out-of-pocket expenses in connection therewith.

We will pay all transfer taxes, if any, applicable to the exchange of the
original notes pursuant to the exchange offer. If, however, a transfer tax is
imposed for any reason other than the exchange of the original notes pursuant
to the exchange offer, then the amount of any such transfer taxes (whether
imposed on the registered holder or any other persons) will be payable by the
tendering holder. If satisfactory evidence of payment of such taxes or
exemption therefrom is not submitted with the Letter of Transmittal, the
amount of such transfer taxes will be billed directly to the tendering holder.

Consequences Of Failure To Exchange

Participation in the exchange offer is voluntary. Holders of the original
notes are urged to consult their financial and tax advisors in making their
own decisions on what action to take.

Original notes that are not exchanged for exchange notes pursuant to the
exchange offer will remain "restricted securities" within the meaning of Rule
144 under the Securities Act. Accordingly, such original notes may be resold
only:

. to us or any of our subsidiaries,

39
<PAGE>

. so long as the original notes are eligible for resale pursuant to Rule
144A, to a person whom the seller reasonably believes is a "qualified
institutional buyer" within the meaning of Rule 144A under the
Securities Act, purchasing for its own account or for the account of a
qualified institutional buyer, to whom notice is given that the resale,
pledge or other transfer is being made in reliance on Rule 144A,

. outside the United States to non-U.S. Persons in an offshore transaction
in compliance with Rule 904 under the Securities Act,

. pursuant to an exemption from registration under the Securities Act in
accordance with Rule 144 (if available),

. to an institutional "accredited investor" that, prior to such transfer,
furnishes to the Trustee a signed letter containing certain
representations and agreements relating to the restrictions on transfer
of the original notes and, if such transfer is in respect of a principal
amount of original notes at the time of transfer of less than $500,000,
an opinion of counsel acceptable to us that the transfer is in
compliance with the Securities Act, or

. pursuant to an effective registration statement under the Securities
Act,

in each case in accordance with any applicable securities laws of any state of
the United States and subject to certain requirements of the Trustee being
met. The liquidity of the original notes could be adversely affected by the
exchange offer. See "Risk Factors--A Failure to Participate in the Exchange
Offer May Have Adverse Consequences."

Resales Of The Exchange Notes

Based on certain no-action letters issued by the staff of the Securities
and Commission, we believe that the exchange notes or interests therein issued
pursuant to the exchange offer in exchange for original notes or interests
therein may be offered for resale, resold and otherwise transferred by you
(unless you are a broker-dealer who purchases such exchange notes directly
from us to resell pursuant to Rule 144A or any other available exemption under
the Securities Act) without compliance with the registration and prospectus
delivery requirements of the Securities Act; provided that

. you are acquiring the exchange notes in the ordinary course of your
business,

. you are not participating, do not intend to participate, and have no
arrangement or understanding with any person to participate, in the
distribution of exchange notes, and

. you are not an affiliate of the Company, within the meaning of Rule 405
under the Securities Act.

However, if you acquire exchange notes in the exchange offer for the
purpose of distributing or participating in the distribution of the exchange
notes, you cannot rely on the position of the staff of the Commission in the
no-action letters issued to third parties and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction, unless an exemption from registration
is otherwise available.

Each broker-dealer that receives exchange notes for its own account may be
deemed an "underwriter" within the meaning of the Securities Act and must
acknowledge that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such exchange notes. A broker-
dealer may use this prospectus for any offer to resell, resale or other
transfer of exchange notes received in exchange for original notes which were
acquired by such broker-dealer as a result of market-making activities or
other trading activities. The Letter of Transmittal that accompanies this
prospectus states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act. We have agreed that, for a period of 180
days after the consummation of the exchange offer, we will make this
prospectus available to any broker-dealer for use in connection with any such
offer to resell, resale or other transfer. Please refer to the section in this
prospectus entitled "Plan of Distribution." Subject to certain limitations, we
will take steps to ensure that the issuance of the exchange notes will comply
with state securities or "blue sky" laws.

USE OF PROCEEDS

The exchange offer is being effected to satisfy certain of our obligations
under the registration rights agreement. We will not receive any cash proceeds
from the issuance of the exchange notes offered hereby. In consideration for
issuing the exchange notes, we will receive an equal aggregate principal
amount of original notes. Original notes that are properly tendered in the
exchange offer and not validly withdrawn will be accepted, canceled and
retired and cannot be reissued. Accordingly, the issuance of the exchange
notes will not result in any increase in our outstanding indebtedness.

The net proceeds to the Company from the original issuance of the original
notes were approximately $262.6 million, after deducting underwriting
discounts, commissions and other expenses paid by us. We invested
approximately $104.1 million of the net proceeds in a portfolio of U.S.
government securities, which were then pledged as security for the payment in
full of the first six scheduled interest payments on the notes.

We intend to use the balance of the net proceeds of the offering
(approximately $158.5 million), a substantial portion of which has been loaned
or contributed to our subsidiaries, together with our cash on hand,
investments held for future capital expenditures and borrowings available
under our Senior Secured Credit Facility and the Lucent Facility, to finance
the planned expansion and further development of our networks, including
through acquisitions, and for other general corporate purposes, including to
fund operating losses. Expected capital expenditures for expansion and further
development of our networks primarily include the purchase and installation of
switches, electronic components, fiber optic cable and additional equipment,
and to a lesser extent, acquisitions. Expected expenditures for general
corporate and working capital purposes include (i) expenditures with respect
to our management information system and customer service support
infrastructure, (ii) operating and administrative expenses, primarily those
associated with sales and marketing, with respect to the development and
operation of existing and new networks, and (iii) the funding of operating
losses.

Pending these uses, the net proceeds of the offering of the original notes
have been placed in interest bearing bank accounts or invested in United
States government securities or other short-term, interest bearing investment-
grade securities. Our investment objectives for these funds during this period
will be safety, liquidity and yield, in that order.

(d) Adjusted EBITDA consists of earnings (loss) before net interest, income
taxes, depreciation and amortization charges, stock option compensation
expense (a non-cash charge) and other expense. EBITDA consists of earnings
(loss) before all of the foregoing items except stock option compensation
expense and other expense. These items are provided because they are
measures commonly used in the telecommunications industry. They are
presented to enhance an understanding of the Company's operating results
and they are not intended to represent cash flow or results of operations
in accordance with generally accepted accounting principles. Adjusted
EBITDA and EBITDA are not calculated under generally accepted accounting
principles and are not necessarily comparable to similarly titled measures
of other companies. For a presentation of cash flows calculated under
generally accepted accounting principles, see the Company's historical
financial statements contained in the back of this prospectus.
(e) The ratio of earnings to fixed charges is computed by dividing pretax
income from continuing operations before fixed charges (other than
capitalized interest) by fixed charges. Fixed charges consist of interest
charges, dividend obligations and amortization of debt expense and
discount or premium related to indebtedness, whether expensed or
capitalized, and that portion of rental expense the Company believes to be
representative of interest. Earnings were insufficient to cover fixed
charges by $4,475 for 1994, $1.7 million for 1995, $4.6 million for 1996,
$33.5 million for 1997, $81.9 million for 1998, $56.7 million for the nine

interest expense resulting from the December 1998 refinancing and
expansion of the Senior Secured Credit Facility, the establishment of the
Lucent Facility, the Senior Discount Note offering and the offering of the
original notes as if they occurred on January 1, 1998, earnings would have
been insufficient to cover fixed charges by $132.1 million for 1998 and by
$172.8 million for the nine months ended September 30, 1999.

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

You should read the following discussion and analysis together with the
Company's financial statements, including the notes and the other financial
information appearing elsewhere in this prospectus. Due to our limited
operating history, startup nature and rapid growth, period-to-period
comparisons of financial data are not necessarily indicative, and you should
not rely upon them as an indicator of our future performance. The following
discussion includes forward-looking statements. For a discussion of important
factors that could cause actual results to differ from results discussed in
the forward-looking statements, see the section of this prospectus entitled
"Risk Factors."

Overview

General. We are a facilities-based competitive local exchange carrier
providing telecommunications and data services in Tier III Markets. The
markets in which we operate are predominantly located in the Southeastern and
Midwestern United States. We target as customers business, government and
institutional end-users, as well as Internet service providers, long distance
carriers and wireless service providers. Our objective is to provide our
customers with a complete solution for their communications needs. We
currently provide on-net local dial tone, Internet access, ISDN, long
distance, special access, private line and a variety of other advanced
services and features.

We have invested significant capital and effort in developing our
telecommunications business. This capital has been invested in the development
of our networks, the hiring of an experienced management team, the development
and installation of operating systems, the introduction of services, marketing
and sales efforts, and an acquisition. We expect to make increasing capital
expenditures to build additional networks, to expand current networks to
additional customer buildings, long distance carrier points of presence and
incumbent local exchange carrier central offices, and to broaden our service
offerings, and we may consummate acquisitions. Proper management of our growth
will require us to maintain cost controls, continue to assess market
potential, ensure quality control in implementing our services, as well as to
expand our internal management, customer care and billing and information
systems, all of which will require substantial investment.

The development, construction and expansion of our networks requires
significant capital, a large portion of which is invested before any revenue
is generated. We have incurred, and expect to continue to incur, significant
and increasing operating losses, negative EBITDA and net cash outflows for
operating and investing activities while we expand our network operations and
build our customer base. Based on our experience to date and that of our
competitors, we estimate that a new network will begin to generate positive
EBITDA within 24 to 36 months after commencement of commercial operations.
Construction periods and operating results will vary from network to network.
There can be no assurance that we will be able to establish a sufficient
revenue-generating customer base or gross margins in any particular market or
on a consolidated basis.

The facilities-based competitive local exchange carrier business is capital
intensive. We estimate that the total initial costs associated with the
purchase and installation of fiber optic cable and transmission and switching
equipment, including capitalized engineering costs, will average approximately
$8.0 million to $10.0 million for the fiber optic backbone and switch in each
standard Tier III network, depending upon the size of the market served, the
scope and complexity of the network, and the proportion of aerial to
underground fiber deployment. Our actual costs could vary significantly from
this range. The amounts and timing of these expenditures are subject to a
variety of factors that may vary significantly with the geographic and
demographic characteristics of each market. In addition to equipment and
construction expenditure requirements, upon commencement of the construction
phase of a network we begin to incur direct operating costs for such items as
salaries and rent. As network construction progresses, we incur costs
associated with construction, including preparation of rights-of-way, and
increased sales, marketing, operating and administrative expenses. We
capitalize certain direct costs related to network planning and construction
costs for new networks.

45
<PAGE>

The initial construction of a network consists of deploying the fiber optic
backbone, installing the switch and related electronics and testing the
system. This takes approximately 6 months, depending upon the size and
complexity of the network. The time required during the construction phase is
also significantly influenced by the number of route miles involved, the mix
of aerial versus underground fiber deployment, possible delays in preparing
rights-of-way, provisioning fiber optic cable and electronic equipment, and
required construction permits and other factors, including weather.

Local Services. To facilitate our entry into local services, we plan to
install switching equipment in all of our markets. Switches are in commercial
operation in all of our 23 existing markets. We also intend to install Lucent
switches in any future networks which we may build. Once a switch is
commercially operational, we offer local dial tone and switched data services
such as ISDN, HDSL, Internet access, Local Area Network-to-Local Area Network
interconnect and Wide Area Network services, as well as voice mail and other
custom calling features.

We expect operating margins to improve as switching becomes operational and
switched services are provided on-net, the network is expanded (primarily by
adding buildings to the network), and larger volumes of traffic are carried on
our network. Although under the Telecommunications Act of 1996, incumbent
local exchange carriers are required to unbundle local network elements,
thereby decreasing operating expenses by permitting us to purchase only the
origination and termination services we need, we cannot assure you that such
unbundling will be effected in a timely manner and result in prices favorable
to us.

Revenue. Historically, we have derived our revenue primarily from resale of
switched services, along with special access, private line and Internet access
services provided on our facilities. Future revenues will include increasing
amounts of on-net services, long distance services and value-added data
services, such as ISDN, HDSL, Local Area Network-to-Local Area Network
interconnect, Wide Area Network services, BRI (or Basic Rate ISDN), PRI (or
Primary Rate ISDN) and port wholesale as well as other value-added services
such as Centrex-type services, voice mail and other custom calling features.
We maintain interconnection agreements with incumbent local exchange carriers
in each state in which we operate. Among other things, these contracts govern
the reciprocal amounts to be billed by us for terminating local traffic of
Internet service providers in each state. The Regional Bell Operating
Companies have advised competitive local exchange carriers, such as the
Company, that they do not consider calls in the same local calling area which
are placed by their customers to competitive local exchange carrier customers
which are Internet service providers to be local calls under the
interconnection agreements. The Regional Bell Operating Companies claim that
these calls should be classified as exchange access calls, even though the
Federal Communications Commission exempted local calls for Internet service
providers from payment of access charges. The Regional Bell Operating
Companies claim that, as a result, they do not owe any compensation to
competitive local exchange carriers for transporting and terminating these
calls. The Regional Bell Operating Companies have threatened to withhold, and
in many cases have withheld, reciprocal compensation to competitive local
exchange carriers for the transport and termination of these calls. During
1998, we recognized revenue from incumbent local exchange carriers of
approximately $2.9 million, or 12.9% of 1998 revenue, for these services. The
comparable figure for the nine months ended September 30, 1999 is $4.8
million, or 11.4% of our revenue for that period. Payments of approximately
$135,000 and $375,000 were received from the incumbent local exchange carriers
during 1998 and the nine months ended September 30, 1999, respectively.

46
<PAGE>

recognized related to Internet service provider traffic in Louisiana for the
entire year of 1998 and for the first nine months of 1999. The adjustment
amounted to $4.4 million, of which $1.1 million relates to the year ended
December 31, 1998 and $3.3 million relates to the nine months ended September
30, 1999.

Although incumbent local exchange carriers have disputed the entitlement of
competitive local exchange carriers to reciprocal compensation for termination
of local calls to Internet service providers in jurisdictions other than
Louisiana as well, we have determined to continue to recognize amounts due to
us for reciprocal compensation for calls in jurisdictions other than Louisiana
in which we operate systems because we have concluded, based upon all of the
facts and circumstances, including numerous state public service commission
and state and federal court decisions upholding competitive local exchange
carriers entitlement to reciprocal compensation for such calls, that
realization of such amounts is reasonably assured. In these jurisdictions we
will continue to account for reciprocal compensation with the incumbent local
exchange carriers, including the activity associated with the disputed
Internet service provider traffic, as local traffic pursuant to the terms of
our interconnection agreements. Accordingly, in jurisdictions other than
Louisiana, we will continue to recognize revenue in the period that the
traffic is terminated.

Management believes reciprocal compensation for Internet traffic to be an
industry-wide matter that will ultimately be resolved on a state-by-state
basis. To date, 35 state commissions have ruled on this issue. So far, 31 of
the 35 commissions have determined that reciprocal compensation is owed for
such calls with one of those, Missouri, not requiring payment until the public
service commission sets rates. Several of these cases are presently on appeal.
A number of other state commissions currently have proceedings pending to
consider this matter. On February 26, 1999, the Federal Communications
Commission issued a declaratory ruling on the issue of inter-carrier
compensation for calls bound to Internet service providers. The Federal
Communications Commission ruled that the calls are jurisdictionally mixed, but
largely interstate calls. The Federal Communications Commission determined
that this ruling did not resolve the issue of whether reciprocal compensation
is owed for such calls under existing interconnection agreements. The Federal
Communications Commission noted a number of factors that would allow state
commissions to continue to require payment of reciprocal compensation.

Operating Expenses. Our principal operating expenses consist of network
operating costs, selling, general and administrative expenses, stock option
compensation expense and depreciation and amortization. Network operating
costs include charges from incumbent local exchange carriers for resale
services, termination and unbundled network element charges; charges from long
distance carriers for resale of long distance services; salaries and benefits
associated with network operations, billing and information services and
customer care personnel; franchise fees and other costs, including direct city
administration costs. Network operating costs also include a percentage of
both our intrastate and interstate revenues which we pay as universal service
fund charges. Selling, general and administrative expenses consist of sales
personnel and support costs, corporate and finance personnel and support costs
and legal and accounting expenses. Depreciation and amortization includes
charges related to plant, property and equipment and amortization of
intangible assets, including franchise acquisition costs. Depreciation and
amortization expense will increase as we place additional networks into
service.

Interest Expense. Interest expense includes interest charges on our Senior
Discount Notes, our Senior Secured Credit Facility and the Lucent Facility.
Interest expense also includes amortization of deferred financing costs.
Interest expense will increase substantially in future periods as a result of
the issuance of the notes and increased borrowings under the expanded Senior
Secured Credit Facility and the Lucent Facility, discussed below, to finance
network build-out.

Results of Operations

Nine Months Ended September 30, 1999 Compared To Nine Months Ended
September 30, 1998

Revenue. Revenue increased from $13.6 million for the nine months ended
September 30, 1998 (the "1998 Nine Months") to $42.3 million for the nine
months ended September 30, 1999 (the "1999 Nine Months"). This increase is
primarily attributable to the fact that we derived revenue from 23 markets
during the

47
<PAGE>

1999 Nine Months compared to 11 markets during the 1998 Nine Months. During
1998 and the 1999 Nine Months we recognized revenue which we believed was due
to us from incumbent local exchange carriers for terminating local traffic of
Internet service providers. We determined to recognize this revenue because we
concluded, based upon all of the facts and circumstances known to us at the
time, including numerous state public service commission and state and federal
court decisions upholding competitive local exchange carriers' entitlement to
reciprocal compensation for such calls, that realization of those amounts was
reasonably assured. On October 13, 1999, however, the Louisiana Public Service
Commission ruled that local traffic to Internet service providers in Louisiana
is not eligible for reciprocal compensation. As a result of that ruling, we
determined that we could no longer conclude that realization of amounts
attributable to termination of local calls to Internet service providers in
Louisiana was reasonably assured. Accordingly, we recorded an adjustment to
reduce revenue in the 1999 Third Quarter, which reversed all reciprocal
revenue recognized related to Internet service provider traffic in Louisiana
for the entire year of 1998 and the 1999 Nine Months. The adjustment amounted
to $4.4 million, of which $1.1 million relates to the year ended December 31,
1998 and $3.3 million relates to the 1999 Nine Months.

Excluding the effect of the adjustment, revenue for the 1999 Nine Months
would have been $46.7 million, including $9.2 million of revenue related to
reciprocal compensation. Each of our systems that generated revenue during the
1998 Nine Months generated higher revenue during the 1999 Nine Months.

Revenue for the 1998 Nine Months and 1999 Nine Months included $9.4 million
and $18.3 million, respectively, of revenue derived from resale of switched
services and an aggregate of $4.2 million and $24.0 million (including, after
giving effect to the $4.4 million adjustment for Louisiana, $4.8 million of
revenue related to reciprocal compensation during the 1999 Nine Months),
respectively, of revenue derived from on-net special access, private line and
switched services.

Although incumbent local exchange carriers, such as BellSouth, have
generally withheld payments of amounts due for reciprocal compensation to
competitive local exchange carriers such as the Company for calls to Internet
service providers and disputed the entitlement of competitive local exchange
carriers to reciprocal compensation for such calls in jurisdictions other than
Louisiana as well, we have determined to continue to recognize amounts due to
us for reciprocal compensation for such calls in jurisdictions other than
Louisiana, because we have concluded, based upon all of the facts and
circumstances, including numerous state public service commission and state
and federal court decisions upholding competitive local exchange carriers'
entitlement to reciprocal compensation for such calls, that realization of
such amounts is reasonably assured.

Network Operating Costs. Network operating costs increased from $24.6
million in the 1998 Nine Months to $75.2 million in the 1999 Nine Months. This
increase of $50.6 million was due primarily to the increase in the number of
markets in which we operated in the 1999 Nine Months and the related increases
of $13.4 million in personnel costs, $12.4 million in costs associated with
providing resale services and leasing unbundled network element services, $5.4
million in contracted network support costs, $5.1 million in consultant and
professional services related costs, $2.7 million in reciprocal expense, $1.8
million in facility costs, $1.5 million in telecommunications costs, and $8.3
million in other direct operating costs.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from $15.3 million for the 1998 Nine Months
to $41.7 million for the 1999 Nine Months. This increase of $26.4 million
resulted primarily from increases of $15.6 million in personnel costs, $4.0
million in professional costs (consisting primarily of legal costs), $2.4
million in travel related expenses, and $400,000 in advertising costs, along
with increases in other marketing and general and administrative costs
aggregating approximately $4.0 million.

Stock Option Compensation Expense. Stock option compensation expense, a
non-cash charge, increased from $6.6 million for the 1998 Nine Months to $13.2
million for the 1999 Nine Months. This increase primarily resulted from an
increase in the estimated fair value of the Company's common stock.

48
<PAGE>

Depreciation and Amortization. Depreciation and amortization expense
increased from $5.2 million for the 1998 Nine Months to $19.2 million for the
1999 Nine Months primarily as a result of depreciation expense associated with
the greater number of networks in commercial operation during the 1999 Nine
Months.

Other Expense. During the second quarter of 1999, the Company recorded a
$4.3 million charge to other expense in connection with an unfavorable
arbitration award. The net amount due under the terms of the award was paid in
full in June 1999.

Interest Expense. Interest expense increased from $26.0 million in the 1998
Nine Months to $47.8 million in the 1999 Nine Months. The increase resulted
primarily from the issuance of the original notes in May 1999, additional
accretion on the Senior Discount Notes, and increased interest charges related
to higher borrowings under the Senior Secured Credit Facility. The Company
capitalized interest related to network construction projects of $2.9 million
during the 1998 Nine Months and $3.5 million during the 1999 Nine Months.

Net Loss. For the reasons stated above, net loss increased from $53.7
million for the 1998 Nine Months to $152.2 million for the 1999 Nine Months.

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

Revenue. Revenue increased from $3.4 million for 1997 to $22.4 million for
1998. This increase is primarily attributable to the fact that for 1998 we
derived revenues from 8 markets during the entire period, as well as 14
additional markets from which we began to derive revenues at various points
during the period, as compared to 1997 when we derived revenues from only 1
market during the entire period, and began to derive revenues from 7
additional markets at various points during the year. In addition, each of our
markets from which we derived revenues during 1997 generated increased
revenues during 1998. Revenue for 1997 and 1998 included $2.3 million and
$14.2 million, respectively, of revenue derived from resale of switched
services and an aggregate of $1.1 million and $8.2 million (including $2.9
million of revenue from reciprocal compensation in 1998), respectively, of
revenue derived from on-net special access, private line and switched
services. Resale of switched services represented 67.6% of revenue in 1997 and
63.4% of revenue in 1998.

Network Operating Costs. Network operating costs increased from $7.7
million in 1997 to $37.3 million in 1998. This increase of approximately $29.6
million was due primarily to the increase in the number of markets in which we
operated in 1998 and the related increases of $14.5 million in costs
associated with providing resale services and leasing unbundled network
element services, $5.3 million in personnel costs, $1.6 million in consulting
and professional services costs, $3.4 million in contracted network support
costs, and $1.1 million in facilities related costs, $1.0 million in travel
related costs and $2.7 million in other direct operating costs.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from $9.9 million in 1997 to $24.5 million
in 1998. This increase of approximately $14.6 million resulted primarily from
increases of $8.5 million in personnel costs, $900,000 in professional costs
(consisting primarily of legal costs relating to regulatory matters) and $1.2
million in travel related costs, as well as increases in other marketing and
general and administrative costs aggregating approximately $4.0 million.

Stock Option Compensation Expense. Stock option compensation expense, a
non-cash charge, decreased from $13.9 million in 1997 to $7.1 million in 1998.
These charges are directly impacted by changes in the estimated fair value of
the Company's common stock. The increase in the estimated fair value of such
stock in 1998 was less than the increase in 1997. The expense charge for 1998
includes the net effect of a credit resulting from the termination of the KMC
Telecom Inc. stock option plan, which was substantially offset by a charge
related to the adoption of the KMC Telecom Holdings, Inc., stock option plan,
in September 1998.

Depreciation and Amortization. Depreciation and amortization expense
increased from $2.5 million for 1997 to $9.3 million for 1998, primarily as a
result of depreciation expense associated with the greater number of networks
in commercial operation during 1998, as well as higher amortization of
intangible assets.

49
<PAGE>

Interest Expense. Interest expense increased from $2.6 million in 1997 to
$29.8 million in 1998. This increase resulted primarily from the issuance of
the Senior Discount Notes during the first quarter of 1998, which generated
interest expense of $29.6 million in 1998, as well as the increased expense
attributable to the higher level of borrowings under a credit facility in
1998. The Company capitalized interest of $5.1 million related to network
construction projects during 1998 and $854,000 during 1997.

Net Loss. For the reasons stated above, net loss increased from $32.7
million for 1997 to $76.8 million for 1998.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

Revenue. Revenue increased from $205,000 for 1996 to $3.4 million for 1997.
Revenue increased primarily because we began aggressively marketing our
services in our first market, Huntsville, Alabama, which generated $1.6
million of revenue for 1997. In addition, the network in Melbourne, Florida,
which we purchased during 1997, and the 6 markets from which we began to
generate revenues during 1997, generated an aggregate of $1.8 million in
revenue during 1997. Furthermore, we initiated marketing efforts in May 1997
in all of the markets in which our networks had become commercially
operational or in which we were constructing networks. For 1997, out of total
revenues of $3.4 million, we derived $2.3 million from resale of switched
services and $1.1 million from special access and private line services, of
which $943,000 was generated by on-net services.

Network Operating Costs. Network operating costs increased from $1.4
million for 1996 to $7.7 million for 1997. The increase was due primarily to
costs of $2.4 million associated with hiring personnel and staffing local
offices, $1.8 million in selling, customer care, insurance, facilities and
other direct operating costs and $2.1 million in costs associated with
providing resale services which we initiated in May 1997.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from $2.2 million for 1996 to $9.9 million
for 1997. The increase was due primarily to increases of $4.3 million
attributable to hiring additional personnel in all categories, particularly in
senior management and sales and marketing, $1.1 million in consulting costs
(primarily related to marketing services), and $1.2 million in legal
expenditures (primarily incurred in connection with regulatory activities and
vendor contracts). We expect that selling, general and administrative expenses
will continue to increase in absolute terms as we continue to expand our
network services and marketing activities, but that they will decline as an
overall percentage of revenue.

Stock Option Compensation Expense. Stock option compensation expense, a
non-cash charge, increased from $240,000 in 1996 to $13.9 million in 1997. The
increase was due primarily to an increase in the estimated fair value of KMC
Telecom Inc.'s common stock.

Depreciation and Amortization. Depreciation and amortization expenses
increased from $287,000 for 1996 to $2.5 million for 1997. The increase
reflected the 6 networks that became commercially operational and the one
network that was purchased during 1997 as well as higher amortization of
intangible assets.

Interest Expense. Interest expense increased from $596,000 for 1996 to $2.6
million for 1997, primarily reflecting borrowings under a credit facility in
1997, as well as amortization of deferred financing costs of $561,000. We
capitalized interest of $854,000 related to network construction projects
during 1997. Interest expense will continue to increase as a result of the
issuance of the Senior Discount Notes and to the extent that we increase our
borrowings under the Senior Secured Credit Facility.

Net loss. For the reasons stated above, net loss increased from $4.5
million for 1996 to $32.7 million for 1997.

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

Revenue. Revenue increased from $0 for 1995 to $205,000 for 1996. The
increase in revenue was due to the commencement of the Huntsville network
operations in 1996.

50
<PAGE>

Network Operating Costs. Network operating costs increased from $0 for 1995
to $1.4 million for 1996. This increase was primarily related to the
commencement of operations of the Huntsville network and the related increases
of $550,000 in personnel costs and $850,000 in facilities and other direct
operating costs.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from $1.6 million for 1995 to $2.2 million
for 1996. The increase was due primarily to the hiring of additional senior
management personnel and development of network construction and
implementation plans. Of these amounts, approximately $568,000 for 1996 was
incurred by the Company from affiliated companies owned by Harold N. Kamine
for services (including rent) which we shared with such affiliated companies.

Depreciation and Amortization. Depreciation and amortization increased from
$6,000 for 1995 to $287,000 for 1996. This increase was due primarily to the
completion of construction of the Huntsville network.

Interest Expense. Interest expense increased from $23,000 for 1995 to
$596,000 for 1996. This increase was due primarily to the increase in loans
from stockholders in 1996 and the convertible debt provided by Nassau in 1996,
as well as the amortization of financing costs on the convertible debt.

Net Loss. For the reasons stated above, net loss increased from $1.6
million for 1995 to $4.5 million for 1996.

Stock Compensation Plan

During 1996 and 1997 one of our principal operating subsidiaries granted
options to purchase shares of its common stock pursuant to its 1996 Stock
Plan. On June 26, 1998, the Board of Directors of the Company adopted the 1998
Stock Purchase and Option Plan for Key Employees of KMC Telecom Holdings, Inc.
and Affiliates which authorizes the grant of options to purchase common stock
of the Company. During the third quarter of 1998, the Company replaced the
options to purchase shares of common stock of the subsidiary previously
granted under its 1996 Stock Plan, with options to purchase common stock of
the Company granted under the 1998 Stock Plan and granted options to certain
additional employees of the Company. Upon cancellation of the outstanding
options under the 1996 Stock Plan, the Company reversed all compensation
expense previously recorded with respect to such options. Additionally, to the
extent the fair value of the common stock of the Company exceeded the exercise
price of the options granted under the 1998 Stock Plan, the Company recognized
compensation expense related to such options to the extent vested. The net
effect of the cancellation of the options outstanding under the 1996 Stock
Plan and the grant of options under the 1998 Stock Plan resulted in a credit
to compensation expense of approximately $600,000 in 1998.

Certain provisions in the stock option awards granted under the 1998 Stock
Plan will necessitate that such awards be treated as variable stock
compensation awards pursuant to Accounting Principles Board Opinion No. 25.
Accordingly, compensation expense will be charged or credited periodically
through the date of exercise or cancellation of such stock options, based on
changes in the value of the Company's stock as well as the vesting schedule of
such options. These compensation charges or credits are non-cash in nature,
but could have a material effect on the Company's future reported net income
(loss).

Liquidity and Capital Resources

We have incurred significant operating and net losses as a result of the
development and operation of our networks. We expect that such losses will
continue as we emphasize the development, construction and expansion of our
networks and build our customer base. As a result, there will not be any cash
provided by operations in the near future and we will need to fund the
expansion of our networks. We have financed our operating losses and capital
expenditures with equity invested by our founders, preferred stock placements,
credit facility borrowings and the Senior Discount Notes and the notes.

51
<PAGE>

On May 24, 1999, we issued the original notes in a private offering.
Approximately $104.1 million of the proceeds of the offering were used to
purchase a portfolio of U.S. government securities which have been pledged to
secure the payment of the first six interest payments on these notes
(including the exchange notes). We will use the net proceeds of the offering
to complete the 14 additional networks which we plan to construct by the end
of the first half of 2000.

In February 1999, we issued PIK Preferred Stock and warrants to purchase
common stock for aggregate gross proceeds of $65.0 million to two purchasers.
In April 1999, we issued additional shares of PIK Preferred Stock and warrants
to purchase common stock to one additional purchaser for aggregate gross
proceeds of $35.0 million.

In February 1999, our subsidiary which will own the 14 additional networks
which we currently plan to construct by the end of the first half of 2000,
entered into a secured vendor financing facility with Lucent Technologies Inc.
Under this Lucent Facility, our subsidiary will be permitted to borrow,
subject to certain conditions, up to an aggregate of $600.0 million, primarily
for the purchase from Lucent of switches and other telecommunications
equipment. Currently, only $250.0 million is available under this facility.
The balance of $350.0 million will become available only upon (a) additional
lenders agreeing to participate in the facility so that Lucent's own aggregate
commitment does not exceed $250.0 million and (b) the Company satisfying
certain other requirements, the most significant of which is the Company
raising, and contributing to the subsidiary, at least $300.0 million from the
sale of high yield debt or equity. As of September 30, 1999, the Company had
no borrowings outstanding under the facility.

In December 1998, we refinanced and expanded our $70.0 million senior
secured credit facility with Newcourt Commercial Finance Corporation to a new
$250.0 million facility. Under the refinanced and expanded facility, which is
with a group of lenders led by Newcourt Commercial Finance Corporation, First
Union National Bank, General Electric Capital Corporation and Canadian
Imperial Bank of Commerce, our subsidiaries which own our initial 23 networks
are permitted to borrow up to an aggregate of $250.0 million, subject to
certain conditions, for the purchase of fiber optic cable, switches and other
telecommunications equipment and, once certain financial conditions are met,
for working capital and other general corporate purposes.

In January 1998, we sold units consisting of 12 1/2% Senior Discount Notes
due 2008 and warrants to purchase shares of common stock. The gross proceeds
of the offering were $250.0 million. The Senior Discount Notes are unsecured,
unsubordinated obligations of the Company, pari passu with the notes, and
mature on February 15, 2008.

Net cash provided by financing activities from borrowings and equity
issuances was $219.4 million for 1998 and $332.1 million for the nine months
ended September 30, 1999. Our net cash used in operating and investing
activities was $213.8 million for 1998 and $332.0 million for the nine months
ended September 30, 1999.

We made capital expenditures of $9.1 million in 1996, $61.1 million in 1997
(including the acquisition of the Melbourne, Florida network for a purchase
price of $2.0 million), $161.8 million in 1998 and $218.5 million in the nine
months ended September 30, 1999. We currently plan to make additional capital
expenditures of approximately $132.0 million during the remainder of 1999.
Continued significant capital expenditures are expected to be made thereafter.
The majority of these expenditures is expected to be made for network
construction and the purchase of switches and related equipment to facilitate
the offering of our services. In addition, we expect to continue to incur
operating losses while we expand our business and build our customer base.
Actual capital expenditures and operating losses will depend on numerous
factors, including the nature of future expansion and acquisition
opportunities and factors beyond our control, including economic conditions,
competition, regulatory developments and the availability of capital.

At September 30, 1999, we had outstanding commitments aggregating
approximately $92.8 million related to the purchase of fiber optic cable and
telecommunications equipment as well as engineering services, principally
under our agreements with Lucent Technologies.

52
<PAGE>

At September 30, 1999, we had $125.0 million of indebtedness outstanding
under the Senior Secured Credit Facility, and had $125.0 million in borrowing
capacity available under the Senior Secured Credit Facility, subject to
certain conditions. On the same date, we had no indebtedness outstanding under
the Lucent Facility and had $250.0 million in borrowing capacity available
thereunder.

We have received a signed commitment from Lucent to refinance the existing
Lucent Facility upon terms which would involve the provision of additional
funding to the Company and the resetting of the financial covenants for
periods after the fourth quarter of 1999. We are currently engaged in
discussions with the agents for the lenders under the Senior Secured Credit
Facility which presently contemplates comparable amendments to the financial
covenants in the Senior Secured Credit Facility. We believe that these
negotiations will lead to definitive agreements during the first quarter of
2000. If, however, we are not successful in completing the negotiations as
presently contemplated and amending the financial covenants in the Senior
Secured Credit Facility and the Lucent Facility, it is likely that we will
fail to comply with one or more of the covenants presently contained in those
facilities for the quarter ended March 31, 2000, which failure, unless waived,
would constitute a default under those credit facilities. Given that, as of
this date, the Company has not yet signed definitive agreements with Lucent
and the agents for the lenders under the Senior Secured Credit Facility
implementing the foregoing refinancings, under applicable financial accounting
standards, the Company was required to reclassify the $125.0 million
outstanding at September 30, 1999 under the Senior Secured Credit Facility as
current liabilities in its September 30, 1999 balance sheet. If, as expected,
the Company successfully completes the contemplated refinancings of the Senior
Secured Credit Facility and Lucent Facility prior to the issuance of its
financial statements for the year ended December 31, 1999, the applicable
accounting standards will permit it to classify the amounts outstanding under
the Senior Secured Credit Facility as long-term debt in its balance sheet as
of December 31, 1999. A covenant default under the Senior Secured Credit
Facility or the Lucent Facility is not an automatic default under our other
outstanding indebtedness but, under certain circumstances, may become one,
depending upon the actions of the lenders under the Senior Secured Credit
Facility and Lucent Facility.

We believe that our cash, investments held for future capital expenditures
and borrowings available under the Senior Secured Credit Facility and the
Lucent Facility, together with the net proceeds from our April 1999 issuance
of our PIK Preferred Stock and the proceeds of the offering of the original
notes will be sufficient to meet our liquidity needs through the completion of
our initial 23 networks and the 14 additional networks currently planned for
completion by the end of the first half of 2000, although we can give no
assurance in this regard. Thereafter, we will require additional financing.
However, in the event that our plans change, the assumptions upon which our
plans are based prove inaccurate, we expand or accelerate our business plan or
we determine to consummate acquisitions, the foregoing sources of funds may
prove insufficient to complete all such networks, and we may be required to
seek additional financing sooner than we currently expect. Additional sources
of financing may include public or private equity or debt financings by the
Company, capitalized leases and other financing arrangements.

We can give no assurance that additional financing will be available to us
or, if available, that it can be obtained on a timely basis and on acceptable
terms. Failure to obtain such financing could result in the delay or
abandonment of some or all of our development and expansion plans and
expenditures, which would have a material adverse effect on our business,
financial condition and results of operations. Such a failure could also limit
our ability to make principal and interest payments on our indebtedness,
including the notes, and meet our dividend and redemption obligations with
respect to our preferred stock. The Company has no working capital or other
credit facility under which it may borrow for working capital and other
general purposes. We can give no assurance that such financing will be
available to the Company in the future or that, if such financing were
available, it would be available on terms and conditions acceptable to the
Company.

Year 2000 Compliance

Similar to all businesses, we may be affected by the inability of certain
computer software to distinguish between the years 1900 and 2000 due to a
commonly-used programming convention. Unless such programs are modified or
replaced prior to January 1, 2000, calculations based on date arithmetic or
logical operations performed by such programs may be incorrect. In addition,
the Senior Secured Credit Facility and the Lucent Facility impose certain Year
2000 compliance obligations on us.

Management's plan to address the effect of the Year 2000 issue focuses on
the following areas: applications systems (including our billing system and
financial software), infrastructure (including personal computers and servers
used throughout the Company), and other third party business partners, vendors
and suppliers. Management's analysis and review of these areas is comprised
primarily of the following phases: developing an inventory of hardware,
software and embedded chips; assessing the degree to which each area is
currently compliant with Year 2000 requirements; performing renovations,
repairs and replacements as needed to attain compliance; testing to ensure
compliance; and, developing a contingency plan for each area if our initial
efforts to attain compliance are either unsuccessful or untimely.

Management completed the inventory and assessment phases of the project
during the fourth quarter of 1998. The renovation, repair and replacement
phase and the testing phase have commenced; however, we expect to continue
these phases throughout 1999.

Further, we have completed the initial installation and are continuing the
process of implementing new billing software systems, operational support
systems and financial and personnel software systems. Although these
implementations were made necessary by the expansion of our business and were
not directly related to Year 2000 issues, they have enabled us to utilize new
software for these purposes which the respective suppliers have certified as
Year 2000 compliant.

Costs incurred to date have primarily consisted of labor from the
redeployment of existing information services and operational resources. We
expect to spend approximately $150,000 for these Year 2000 compliance efforts
which will be expensed as incurred. This amount does not include the costs of
the new billing software, operational software and financial and personnel
software systems which we are implementing as a result of the expansion of our
business.

If the software applications of the local exchange carriers, long distance
carriers or others on whose services we depend or with which our systems
interact are not Year 2000 compliant, it could affect our systems which could
have a material adverse effect on our business, financial condition and
results of operations.

Although we do not presently anticipate a material business interruption as
a result of the Year 2000 issue, the worst case scenario if all of our Year
2000 efforts fail would result in a daily loss of revenues of approximately
$250,000 calculated based upon our current revenues.

BUSINESS

The Company

We are a facilities-based competitive local exchange carrier providing
telecommunications and data services in Tier III Markets (population from
100,000 to 750,000). The markets in which we operate are predominantly located
in the Southeastern and Midwestern United States. We target as customers
business, government and institutional end-users, as well as Internet service
providers, long distance carriers and wireless service providers. Our
objective is to provide our customers with a complete solution for their
communications needs. We currently provide on-net local dial tone, Internet
access, ISDN, long distance, special access, private line and a variety of
other advanced services and features.

We currently operate in 23 Tier III Markets. We have constructed robust
fiber optic networks in each of our markets which we believe allow us to
ensure high quality services, facilitate the delivery of value-added and data
services, and effectively control our costs. We currently have Lucent
Technologies Series 5ESS(R)-type switches in commercial operation in all of
our 23 existing markets. We also intend to install Lucent switches in any
future networks which we may build. Over time, we expect to transition the
majority of our customers to our own networks by means of either unbundled
network elements leased from the incumbent local exchange carrier (i.e., the
established local telephone company, such as Ameritech, Bell Atlantic,
BellSouth, SBC or one of the subsidiaries of GTE Corporation or Sprint
Corporation) or direct connections to our own networks.

With cash on hand, investments held for future capital expenditures, the
proceeds of the offering of the notes, the proceeds of our recent private
placements of PIK Preferred Stock and the approximately $250.0 million
expected to be available for that purpose under the Lucent Facility, we
presently plan to construct networks in 14 additional Tier III Markets. We
currently anticipate that these new networks will be completed and placed in
commercial operation by the end of the first half of 2000.

Industry Overview

According to the Federal Communications Commission's Statistics of
Communications Common Carriers, incumbent local exchange carriers in the
United States generated approximately $103.1 billion in revenue in 1997 from
the provision of local exchange services. Local exchange services consist of a
number of service components and are defined by specific regulatory
classifications. For 1997, total revenue by service was (i) interstate access
services revenues of $24.0 billion; (ii) intrastate access services revenues
of $8.0 billion; (iii) basic local service (including dial tone, local area
charges, dedicated point-to-point intra-LATA service and enhanced calling
features) revenues of $52.0 billion; (iv) intra-LATA toll call revenues of
$9.2 billion; and (v) miscellaneous (including provision of directories,
billing and collection services and corporate operations) revenues of $9.9
billion. In addition, the Federal Communications Commission reported that
total toll service revenues in the United States in 1997 were $100.8 billion.

Local exchange and long distance services represent a large, steadily
growing market opportunity currently dominated by the incumbent local exchange
carriers and the major long distance companies.

A number of important trends are reshaping the approximately $230.0 billion
U.S. communications industry, creating substantial opportunities for
competitive local exchange carriers beyond capturing market share from
incumbent local exchange carriers in local exchange services. These trends
include (i) increasing customer demand for high speed, broadband services,
such as the Internet and personal computer- and Internet protocol-based
applications, (ii) the emergence of e-commerce as a new paradigm for business
transactions and (iii) continued consolidation among service providers to
broaden their service bundle and technical capabilities.

By leveraging customer relationships and bundling service offerings,
competitive local exchange carriers have begun to exploit a variety of high-
growth, value added services opportunities, including high speed Internet
access, HDSL, Local Area Network and Wide Area Network connectivity, managed
network services, Virtual Private Networks, remote access, and e-commerce
services. We believe that new entrants have an excellent

55
<PAGE>

opportunity to establish themselves as leading providers of such value-added
services, particularly in Tier III Markets. Prior to the passage of the
Telecommunications Act of 1996, many incumbent local exchange carriers have
underinvested in human resources (including sales, sales support and
engineering personnel), fiber and networking infrastructure in Tier III
Markets.

High-speed connectivity has become important to business due to the
dramatic increase in Internet usage and the proliferation of personal
computer- and Internet protocol-based applications. According to International
Data Corporation, an independent telecommunications and technology research
company, the number of Internet users worldwide reached approximately 69
million in 1997 and is forecasted to grow to approximately 320 million by
2002. The popularity of the Internet with consumers has also driven the rapid
growth in exploiting the Internet as a commercial medium, as businesses
establish Web sites, corporate intranets and extranets and implement e-
commerce applications to expand their customer reach and improve their
communications efficiency. International Data Corporation estimates that the
value of goods and services sold worldwide through the Internet will increase
from $12.0 billion in 1997 to over $400.0 billion in 2002. Importantly, these
applications are increasingly viewed as mission-critical by businesses of all
sizes, making the availability of broadband capacity, network quality, a
value-added services portfolio and technical capability an important
competitive distinction among service providers.

Business Strategy

The principal elements of our business strategy include:

Focus on Tier III Markets. We intend to operate in Tier III Markets with
attractive demographic, economic, competitive and demand characteristics. We
believe that incumbent local exchange carriers tend to focus their efforts on
larger markets and generally underserve and underinvest in Tier III Markets.
We also believe that there is generally significantly less competition from
other facilities-based competitive local exchange carriers in Tier III
Markets, which allows us to gain market share more rapidly than we could
expect in Tier I and Tier II Markets. In addition, network construction, labor
and rights-of-way costs are generally lower in Tier III Markets than in Tier I
and Tier II Markets. For example, many Tier III Markets permit significant
aerial deployment of fiber optic cable which is less expensive than the buried
deployment required in many Tier I and Tier II Markets. We estimate that
approximately 70% of our fiber is deployed aerially. We select target markets
from among the approximately 250 Tier III Markets in the United States by
first identifying those markets that do not yet have significant, established
competitors to the existing incumbent local exchange carrier, and by then
reviewing the specific demographic, economic, competitive and
telecommunications demand characteristics of such markets to determine their
suitability for the types of services which we offer. We estimate market
demand on the basis of the concentration of potential business, government and
institutional end-user customers in the market and the general economic
prospects for the area. During 1999 we also intend to investigate the
technological and market feasibility of serving Tier IV Markets near our Tier
III Markets. As part of this investigation we currently plan to begin
construction on fiber optic networks in two Tier IV Markets during 1999.

Comprehensive Fiber Networks. We build geographically extensive, full
service, facilities-based networks. We believe such networks provide
significant operating leverage, facilitate the capture of market share, and
are likely to deter other competitive local exchange carriers from attempting
to penetrate our markets due to the cost of constructing a competing network
of equal capability. Prior to both the initial construction of our network
backbone and any subsequent network expansion, we perform detailed rate of
return analyses to justify the capital expenditures involved. In all of our 23
existing markets, we have completed our backbone construction connecting the
market's central business district with outlying office parks, large
institutions, the locations of

56
<PAGE>

long distance carriers' transmission equipment and major incumbent local
exchange carrier central offices. We intend to continue to expand our existing
networks in response to anticipated customer demand.

Local Presence With Personalized Customer Service. We seek to capture and
retain customers through local, personalized sales, marketing and customer
service programs. To this end, we:

. establish sales offices in each market in which we operate a network,

. strive to recruit our city directors and sales staff from the local
market,

. rely principally on a face-to-face selling approach, and

. support our sales staff with locally based customer service and
technical support personnel.

Most of our existing sales personnel are local residents who have
previously worked for the incumbent local exchange carrier or other
telecommunications companies. We believe that our "Creative Solutions with a
Hometown Touch"(TM) sales approach is very important to customers in Tier III
Markets, who do not typically receive focused local sales contact or customer
support from the incumbent local exchange carrier. We seek to build long-term
relationships with our customers by responding rapidly and creatively to their
telecommunications needs.

Focus on Value-Added Data Services. We believe it is strategically
important to offer these services because:

. they provide for competitive differentiation,

. they present a substantial margin opportunity,

. as a facilities-based provider, we are able to offer these services
without significant marginal operating costs, and

. incumbent local exchange carriers have underinvested in facilities and
sales forces related to these services.

Low Cost Construction. It is our practice to use innovative "switch-in-a-
box" construction and deployment techniques for most of our networks. Using
these techniques, transmission, switching and power equipment are pre-
installed by Lucent under controlled factory conditions in portable,
weatherproof, storm-proof concrete buildings delivered to the Lucent facility
by our contractor. The completed buildings are then shipped to the appropriate
city for final installation, reducing costs, installation risks and time to
market.

Quality Operations Support System. We are developing a high quality
operations support system to provide us with comprehensive billing, order
processing and customer care software for all of our existing and contemplated
services. This system is designed to provide us with a single "flow-through"
order form that will entail several components, allowing each order to be
tracked from service provisioning through to complete installation. We believe
that this system will allow us to quickly address customer concerns and
provide us with a competitive advantage in customer service and operations
efficiency. Initial installation of the new operational support systems was
made during the third quarter of 1999, with development and expansion to
continue over the next 12 to 18 months.

Experienced Management Team. Our senior management team includes
individuals with over 250 years of experience, collectively, in the
telecommunications industry. It is led by Harold N. Kamine, Chairman of the
Board of Directors, and Michael A. Sternberg, the Company's President and
Chief Executive Officer. Other members of the team include Roscoe C. Young II,
Chief Operating Officer, James D. Grenfell, Executive Vice President, Chief
Financial Officer and Secretary, James L. Barwick, Senior Vice President and
Chief Technology Officer, Tricia Breckenridge, Executive Vice President--
Business Development and Paul R. DiMarco, Vice President--Information
Technology and Chief Information Officer.

Services

General. We have historically provided dedicated access service and have
also resold switched services which we purchased from incumbent local exchange
carriers. In December 1997, we began providing our own on-net switched
services to our customers. For 1997 on-net switched services accounted for 32%
of our revenue and resale services accounted for 68% of our revenue. For 1998
on-net switched services accounted for 37% of our revenue and resale services
accounted for 63% of our revenues. For the nine months ended September 30,
1999 on-net switched services accounted for 57% of our revenue and resale
services accounted for 43% of our revenues.

Private Line and Special Access Services. We currently provide various
types of on-net dedicated services which permit the transmission of voice and
data between two points over circuits dedicated to a particular customer.
Private line service involves the provision of a private, dedicated
telecommunications connection of a customer's different locations. For these
services we offer several types of dedicated circuits that have different
capacities. DS-1 and DS-3 circuits are dedicated lines that can carry up to 24
and 672 circuits, respectively. Special access service involves leasing
private, dedicated telecommunications lines running over our networks to long
distance carriers. The long distance carriers use these lines to connect
different locations where they have installed transmission equipment within
the market, to connect locations where they have installed transmission
equipment to the transmission equipment locations of other long distance
carriers within the market, or to connect large customers directly to the
locations of their transmission equipment. In addition to DS-0, DS-1 and DS-3
dedicated circuits, we also offer OC3, OC12 and OC48 circuits for these
services. These OC circuits provide the fastest transmission available for
carriers and large business users.

Switch-Based Services. We have added and continue to add capability to
provide local dial tone and switched access origination and termination
services to our networks. Switches are currently in commercial operation in
all of our 23 existing markets. Over time, we expect to transition the
majority of our customers to our own networks by means of either unbundled
network elements leased from the incumbent local exchange carrier or direct
connections to our own networks; however this can be a time consuming task.
See "Risk Factors--We Will Be Reliant on Incumbent Local Exchange Carriers for
Interconnection and Provisioning." We have entered into interconnection
agreements with incumbent local exchange carriers for all of our existing
networks, although our agreement with BellSouth has expired.

Long Distance. We offer a full range of long distance products including
inter-LATA, intra-LATA, interstate, international, calling card and 800-number
services. During the first quarter of 1999, we introduced KMC-branded operator
services, directory services, prepaid phone cards and audio-conference
services. We offer these services both on-net and off-net. We offer long
distance services on a resale basis by entering into wholesale agreements with
various long distance carriers to deliver these services. We believe that many
of our customers will prefer the option of purchasing long distance services
from us as part of a one-stop telecommunications solution.

Centrex-type Services. We provide Centrex-type services. By using Centrex-
type services instead of purchasing and installing a switching system on its
own premises, a customer can substantially reduce its capital expenditures and
the fixed costs associated with maintaining telecommunications equipment. We
introduced our ClearStarsm Advantage service in all of our operational markets
during the first quarter of 1999. It has been designed to support multiple
applications, ranging from basic access services to services focused on
desktop applications. The basic access service connects to a customer's
internal system and is equipped with up to 14 features including call
forwarding, speed dialing and call transfer capabilities. More sophisticated
levels of service are designed to replace portions of a customer's existing
telecommunications system. At the high end of service offerings is ClearStarsm
Advantage Plus, a packaged, end-to-end offering which combines all of the
basic features with Basic Rate ISDN network access, advanced feature
functionality, voice messaging and Lucent ISDN multi-featured telephone sets.

New Data Services Offerings. We introduced ISDN services in late 1998. Data
services represented approximately 7% of our revenue for the first nine months
of 1999. We currently plan to expand our capabilities

58
<PAGE>

by introducing additional data services in 1999. We believe that these
services will enhance our ability to provide an integrated turnkey solution to
our customers' voice, data and video transmission requirements. These data
services will include:

. Basic Rate ISDN. Basic Rate ISDN, or BRI, provides customers the
potential of 144 kilobits per second of digital communications via a single
network facility interface. We believe it will be attractive to small and
medium size customers, since it provides dial-up access to the Internet,
and other dial-up data applications, while simultaneously providing the
ability to integrate voice traffic on a single network facility.

. Primary Rate ISDN. Primary Rate ISDN provides customers the
equivalent of 1.544 megabits per second of digital communications via a T-1
type facility, with 23 channels for voice and data communications and a
24th channel providing network signaling and control for the services. We
focus our Primary Rate ISDN sales efforts on (i) Internet service providers
who use Primary Rate ISDN as a means of supporting customer access to their
operations, and (ii) end-user customers who use Primary Rate ISDN as a
network access facility for their internal telecommunications systems.

. Port wholesale. Port wholesaling is a technology that provides large
bandwidth users with data switching capability at the network level,
allowing them to acquire capacity as required without investing in data
switching equipment. Port wholesaling gives us the ability to provide data
switching to Internet service providers by allowing data calls to be
terminated through the port wholesale equipment rather than the switch.
This enables the Internet service provider to more cost effectively manage
its data requirements while, at the same time, increasing the efficiency
and capacity of the Lucent Technologies Series 5ESS(R)- type switch.

. HDSL. HDSL is a method of using unconditioned, copper wire pairs for
high bit-rate data transport for use in the "last mile" connecting our
network backbone ring to the customer's premises. We plan to utilize HDSL
to provide high bandwidth data and video service to small and medium size
customers.

. Frame Relay/ATM. Frame relay and ATM, or asynchronous transfer mode,
are used by some of our data customers as a fast data transport service for
Wide Area Networks. Today we resell these services. In the future we intend
to provide these services over our own network and utilize a third party
provider for transport outside our network.

We plan to remain flexible in responding to evolving customer demands for data
services.

Local Networks

As part of determining the economic viability of a network in a particular
market, we review the demographic, economic, competitive and
telecommunications demand characteristics of the market. We estimate market
demand using data gathered from long distance carriers, the Federal
Communications Commission, local sources, site visits and specific market
studies commissioned by the Company, the concentration of potential business,
government and institutional end-user customers and the general economic
prospects for the area.

Once we target a market for development, we design a network to provide
access to approximately 70% of the business customers in that market either
through direct connections to our network or through unbundled network
elements leased from the incumbent local exchange carrier. Typically, we
construct a "self-healing" synchronous optical network ("SONET") architecture
backbone ring to provide coverage of the major business districts, government
offices, hospitals, office parks and universities, the principal locations of
the transmission equipment of long distance carriers offering services in the
area, and the incumbent local exchange carrier's central office(s). Following
construction of our backbone network, we expect to build additional loops to
increase the size of our addressable market.

(1) Refers to the date on which testing is completed and the switch is first
available to carry customer traffic. Fiber optic networks typically become
commercially operational for non-switched traffic in the quarter before
the switch is available to carry customer traffic. The quarters presented
for new networks represent our estimate of the calendar quarters in which
the new networks will be commercially operational. We cannot assure you
that the new networks will be commercially operational when estimated.
(2) Represents (i) for existing networks, current owned operational route
miles and (ii) for new networks, the number of operational route miles
currently estimated to be owned and operational at the time the network
becomes commercially operational.
(3) Addressable by either unbundled network elements leased from the incumbent
local exchange carrier or by a direct connection to our own network. We
define a commercial building as one with greater than ten employees.
(4) Represents all active switched channels we provide to customers either by
resale via the incumbent local exchange carrier's network, by unbundled
network elements leased from the incumbent local exchange carrier, or by
direct connection to our own network.
(5) Represents all active dedicated DS-0, DS-1 and DS-3 circuits we provide to
customers expressed on a DS-0 basis.

The construction of a network requires us to obtain municipal franchises
and other permits. These rights are typically the subject of non-exclusive
agreements of finite duration providing for the payment of fees by the Company
or the provision of services by the Company to the municipality without
compensation. In addition, we must secure rights-of-way and other access
rights which are typically provided under non-exclusive multi-year agreements,
which generally contain renewal options. Generally, these rights are obtained
from utilities, incumbent local exchange carriers, other competitive local
exchange carriers, railroads and long distance carriers. The
Telecommunications Act of 1996 requires most utilities to afford access to
rights-of-way to competitive local exchange carriers on non-discriminatory
terms and conditions and at reasonable rates. However, there can be no
assurance that delays or disputes will not occur. Our agreements for rights-
of-way and similar matters generally require us to indemnify the party
providing such rights. Such indemnities could make us liable for actions
(including negligence) of the other party.

61
<PAGE>

Our requirements for a planned network are communicated to our engineering
group which finalizes the route and completes the network's design.
Independent construction and installation contractors are selected through a
competitive bidding process. Our own personnel negotiate required contracts
and rights-of-way and supervise the construction, installation and testing of
network components prior to commencing commercial service. Cable, equipment
and supplies required for the networks are available from a variety of sources
at competitive rates. The construction period for a new network varies
depending upon such factors as the number of backbone route miles to be
installed, the relative use of aerial as opposed to buried cable deployment,
the initial number of buildings targeted for connection to the network
backbone and other factors. Based upon our experience, we believe that a new
fiber optic network can be made commercially operational within approximately
6 months after construction commences.

In a typical Tier III Market, selected office buildings are connected to
our network by network backbone extensions or unbundled network elements
leased from the incumbent local exchange carrier. Within each building,
customer equipment is connected to Company-provided electronic equipment where
customer transmissions are digitized, combined and converted to an optical
signal. The traffic is then transmitted through the network backbone to the
Company's local central office where it can be routed to its ultimate
destination.

We are able to expand our reach in a market by collocating equipment in an
incumbent local exchange carrier's central office and leasing unbundled
network elements from that incumbent local exchange carrier in order to reach
customers located in buildings which are not directly connected to our own
backbone ring. We attempt to place collocation equipment in a sufficient
number of incumbent local exchange carrier central offices to allow us to
reach approximately 70% of the business customers in a given market, either by
means of such unbundled network elements or direct connections to our own
network. The decision as to whether to collocate in a specific central office
is based upon the number of business lines, number and type of businesses,
number of households and the location of the central office within the market.

Our networks consist of our fiber optic backbones, fiber laterals and
unbundled network elements. Our networks allow for high speed, high quality
transmission of voice, data and video communications. We typically install
backbone fiber optic cables containing 48 to 144 fiber strands which have
significantly greater bandwidth carrying capacity than other media. Our OC-48
SONET networks support up to 32,256 simultaneous voice conversations over a
single pair of fiber optic fibers. We expect that continuing developments in
compression technology and multiplexing equipment will increase the capacity
of each fiber, thereby providing more bandwidth carrying capacity at
relatively low incremental costs.

We currently offer end-to-end fully protected fiber services utilizing
SONET ring architecture which routes customer traffic simultaneously in both
directions around the ring to provide protection against fiber cuts. If a line
is cut, traffic can simply be reversed and sent to its destination around the
other side of the ring. Back-up electronics become operational in the event of
failure of the primary components.

We monitor our fiber optic networks and electronics seven days per week, 24
hours per day, using a combination of local and national network control
centers. Local network monitoring is accomplished by means of an automatic
notification system that monitors for any system anomaly. This system provides
instantaneous alarms to an on-call network technician whenever an anomaly is
detected. The local market technician is trained in network problem resolution
and provides on-site corrective procedures when appropriate. A national
Network Reliability Center, located in Denver, Colorado, acts as the focal
point for all of our operating networks, providing integrated and centralized
network monitoring, and correlation and problem management. The Network
Reliability Center has access to all operating networks and can work
independently of the local systems to effect repair or restoration activities.
The Network Reliability Center is currently provided by Lucent on a
contractual basis. In the future, we may develop our own national center.

We manage our network systems both locally and centrally. Customer service
calls and maintenance are primarily handled through the local offices. In
addition, as described above, we contract to provide integrated monitoring of
our networks via Lucent's Network Reliability Center. This is accomplished by
the use of a

62
<PAGE>

sophisticated integrated management system that is connected to all of our
locations, including our Duluth, Georgia, operations center. With this system
the Network Reliability Center is capable of accessing all available
information regarding the configuration and operating condition of any network
components in use. This proactive monitoring capability is further augmented
by a 24 hour a day, seven day a week call center, also provided by Lucent at
the Network Reliability Center, that receives, tracks and manages all customer
calls and issues to satisfactory conclusion. The call center works with the
Company's own customer care representatives and engineers in the Duluth
facility to ensure that timely and consistent service is provided.

Sales and Marketing

We target our sales and marketing activities at three separate customer
groups: retail, national accounts and wholesale. Retail customers are composed
of business, government and institutional telecommunications and data services
end-users and local Internet service providers. National accounts are usually
large corporations which have branches or local offices within our markets,
but which make their buying decisions centrally from their corporate
headquarters. Wholesale customers typically consist of long distance carriers,
wireless service providers and national Internet service providers. As of
September 30, 1999, we had approximately 200 employees engaged in sales and
marketing activities.

Retail Customers. We target retail customer segments such as business,
government, healthcare and educational institutions. We target all business
customers in our markets as well as local Internet service providers. Each
city's local sales staff is responsible for calling on the retail customers in
its market.

Sales Personnel. We establish local sales offices in each market that we
serve. Initially, each local sales office is staffed by a City Director and 2
or 3 salespersons, which increases to between 4 and 6 as our operations in the
market expand. All sales personnel are hired locally since we believe that
knowledge of, and contacts in, a local market are key factors for competitive
differentiation and commercial success in a Tier III Market. We believe that
this local focus will help to set us apart from the incumbent local exchange
carriers, our principal competitors.

City Directors. We seek to hire local, seasoned telecommunications
managers, with sales experience, as City Directors. City Directors assist with
the initial network buildout and oversee the daily operations of their
network, in addition to managing sales staff and market development. Daily
operations responsibilities include monitoring provisioning, customer service,
pricing decisions and the billing process. A City Director works with senior
management in the strategic planning process, including capital expenditures
and budget planning. They perform cash flow analysis for fiber connections of
new buildings to the network, and participate in planning fiber network
extensions in their markets.

National Accounts. While there are few Fortune 500 companies with
headquarters located in our operating cities, there are branches and local
offices of large corporations within our market areas. Often these large
corporations make their buying decisions centrally, either through their
telecommunications or MIS functions, which are normally located at corporate
headquarters. Our national accounts sales organization is structured to assist
them in determining requirements for their various locations within our
markets. We believe that this focus on national accounts will further increase
our market penetration with large companies in our cities.

Wholesale Customers. We currently target the major long distance carriers
such as AT&T, MCI WorldCom and Sprint, Internet service providers, wireless
service providers and other competitive local exchange carriers, through our
carrier group. We believe that we can effectively compete to provide access to
these customers based on price, reliability, technology, route diversity,
ease-of-ordering and customer service. Historically, long distance carriers
have paid significant charges to incumbent local exchange carriers to
terminate long distance calls. We provide these services at a discount. In
addition, to the extent that incumbent local exchange carriers begin to
compete with long distance carriers in providing long distance services, the
long distance carriers have a competitive incentive to move access business
away from incumbent local exchange carriers to competitive local exchange
carriers such as the Company. Wireless service providers, who need network
backbone to transport

63
<PAGE>

calls, are an active customer base, as are other competitive local exchange
carriers as wholesale users. Revenues from access services may decline in
future years due to a change in pricing proposed by the Federal Communications
Commission.

Suppliers

Lucent. We have contracted with Lucent, as our primary supplier, to
purchase switching, transport and digital cross connect products. Lucent has
also agreed to implement and test our switches and related equipment. In
addition, Lucent and the Company have entered into an agreement pursuant to
which Lucent has agreed to monitor our switches on an on-going basis. Lucent
currently holds $31.9 million of our PIK Preferred Stock.

Billing Support Systems Implementation. In the second quarter of 1999, we
installed software developed by Billing Concepts Systems, Inc. to provide us
with comprehensive billing functionality, including the ability to collect
call detail records, message rating, bill calculation, invoice generation,
commission tracking, customer care and inquiry, collections management, and
quality assurance. We anticipate that the Billing Concepts software will
result in our ability to produce a single bill covering all of the products
and services that we provide to a customer. Additional development of the new
billing systems will take place over the next 12 months.

Operational Support Systems Implementation. We have entered into an
agreement with Eftia OSS Solutions Inc. to develop operational support
systems. These systems will manage service order processing, circuit and asset
inventory, telephone number inventory and trouble administration. The
operational support system's responsibilities will be expanded during the
later phases of the project to include workforce management, local number
portability management, network management, service bureau interfaces, and
Internet-based service inquiry. We anticipate the system will automate
operational support activities and provide a means of managing operational
performance of our business. Initial installation of the new operational
support systems was made during the third quarter of 1999, with development
and expansion to continue over the next 12 to 18 months.

Competition

Overview. The telecommunications industry is highly competitive. Our
principal competitors in Tier III Markets will be the incumbent local exchange
carriers. In most instances the incumbent local exchange carrier is one of the
Regional Bell Operating Companies (such as Ameritech, Bell Atlantic, BellSouth
or SBC), one of GTE Corporation's subsidiaries or one of Sprint Corporation's
subsidiaries. Incumbent local exchange carriers presently have almost 100% of
the market share in those areas we consider our market areas. Because of their
relatively small size, we do not believe that Tier III Markets can profitably
support more than two competitors to the incumbent local exchange carrier.

Other competitors may include other competitive local exchange carriers,
microwave and satellite carriers, wireless telecommunications providers and
private networks built by large end-users. Potential competitors (using
similar or different technologies) include cable television companies,
utilities and Regional Bell Operating Companies seeking to operate outside
their current local service areas. In addition, there may be future
competition from large long distance carriers, such as AT&T and MCI WorldCom,
which have begun to offer integrated local and long distance
telecommunications services. AT&T also has announced its intention to offer
local services using a new wireless technology. Consolidation of
telecommunications companies and the formation of strategic alliances within
the telecommunications industry, as well as the development of new
technologies, could give rise to significant new competitors to the Company.

Both the long distance business and the data transmission business are
extremely competitive. Prices in both businesses have declined significantly
in recent years and are expected to continue to decline. In the long distance
business, we will face competition from large carriers such as AT&T, MCI
WorldCom and Sprint. We will rely on other carriers to provide transmission
and termination for our long distance traffic and therefore will be dependent
on such carriers.

64
<PAGE>

We expect to experience declining prices and increasing price competition.

Incumbent Local Exchange Carriers. Our principal competitors for local
exchange services are the Regional Bell Operating Companies, GTE Corporation's
subsidiaries and Sprint Corporation's subsidiaries. As a recent entrant in the
integrated telecommunications services industry, we have not yet achieved a
significant market share for any of our services. In particular, the incumbent
local exchange carriers:

. have long-standing relationships with their customers,

. have financial, technical and marketing resources substantially greater
than ours,

. have the potential to fund competitive services with revenues from a
variety of businesses, and

. currently benefit from certain existing regulations that favor the
incumbent local exchange carriers over us in certain respects.

Recent regulatory initiatives allow us, as a competitive local exchange
carrier, to interconnect with incumbent local exchange carrier facilities.
This provides increased business opportunities for us. However, these
regulatory initiatives have been accompanied by increased pricing flexibility
for, and relaxation of regulatory oversight of, the incumbent local exchange
carriers. If the incumbent local exchange carriers engage in increased volume
and discount pricing practices or charge us increased fees for interconnection
to their networks, or if the incumbent local exchange carriers seek to delay
implementation of our interconnection to their networks, our business,
financial condition and results of operations and our ability to make payments
on the notes could be adversely affected.

To the extent that we interconnect with and use incumbent local exchange
carrier networks to serve our customers, we are dependent upon their
technology and capabilities. We will become increasingly dependent on
interconnection with incumbent local exchange carriers as switched services
become a greater percentage of our business. The Telecommunications Act of
1996 imposes interconnection obligations on incumbent local exchange carriers,
but we cannot assure you that we will be able to obtain the interconnection we
require at rates, and on terms and conditions, that will permit us to offer
switched services at desirable rates, terms and conditions. In the event that
we experience difficulties in obtaining appropriate and reasonably priced
service from the incumbent local exchange carriers, our ability to serve our
customers would be impaired.

Competitive Local Exchange Carriers and Other Competitors. We will compete
from time to time with other competitive local exchange carriers. It is likely
that in several of our markets we will face competition from two or more
facilities-based competitive local exchange carriers. After the investment and
expense of establishing a network and support services in a given market, the
marginal cost of carrying an additional call is negligible. Accordingly, in
Tier III Markets where there are 3 or more facilities-based competitive local
exchange carriers, we expect substantial price competition. We believe that
operations in such markets are likely to be unprofitable for one or more
operators.

The competitive local exchange carrier competitors in our 23 existing
markets include, among others:

e.spire resell BellSouth services. American MetroCom reports a switch and had
plans to construct a network in the first quarter of 1999, although, as of
October 1999, American MetroCom had not applied for construction permits.

(3) Shreveport--AT&T Local Services has a switch. e.spire has a network
consisting of 2.5 route miles, but does not have a switch.

(5) Savannah--AT&T Local Services has a switch. However, it is not actively
marketing services in Savannah at the present time.

66
<PAGE>

Local Services has a point of interface switch and is offering both business
and residential service. Teligent is a wireless competitive local exchange
carrier with a switch.

(14) Topeka--AT&T Local Services has a switch.

(18) Fort Myers--ITC DeltaCom has a switch and leases fiber. TCG (now AT&T
Local Services) reports a switch.

(19) Longview--Golden Harbor is a business and residential reseller and
reports a non-active switch. TCG of Dallas (now AT&T Local Services) also
reports a non-active switch.

(20) Sarasota--ICI-Intermedia Communications provides switch-based service
from its fiber network in Tampa.

(21) Pensacola--ITC DeltaCom has a switch, a long haul fiber network and
resells services. AT&T Local Services has a point of interface switch.

The competitive local exchange carrier competitors in the 14 markets in
which we are presently developing new networks include, among others:

(2) Lansing--MCI WorldCom has a 5 route mile fiber network and a switch.
AT&T Local Services has a point of interface switch.

67
<PAGE>

(8) Monroe--ITC DeltaCom reports a switch, has a long haul fiber network,
and is reselling services.

(11) Biloxi/Gulfport--Actel is leasing fiber from Frontier and is back
hauling from their switch in Mobile, AL. AT&T Local Services has a switch.

(13) Johnson City/Kingsport--There is currently no competitive local
exchange carrier competitor in this market.

68
<PAGE>

We believe that there may be additional competitors that have formulated
plans to enter our markets.

We expect to face competition in each of our markets. However, we believe
that our commitment to build a significant network, deploy switches and
establish local sales and support facilities at the outset in each of the Tier
III Markets which we target should reduce the number of facilities-based
competitors and drive other entrants to focus on the resale of incumbent local
exchange carrier service or our services or to invest in other markets. We
believe that each market will also see more agent and distributor resale
initiatives.

Regulation

Our services are subject to varying degrees of federal, state and local
regulation. The Federal Communications Commission exercises jurisdiction over
facilities of, and interstate and international services offered by,
telecommunications common carriers. The state regulatory commissions retain
jurisdiction over the same facilities and services to the extent they are used
to originate or terminate intrastate communications. Local governments
sometimes impose franchise or licensing requirements on competitive local
exchange carriers.

Federal Regulation

We are regulated at the federal level as a nondominant common carrier
subject to minimal regulation under Title II of the Communications Act of
1934. The Communications Act of 1934 was substantially amended by the
Telecommunications Act of 1996. This legislation is designed to enhance
competition in the local telecommunications marketplace by:

. removing state and local entry barriers,

. requiring incumbent local exchange carriers to provide interconnection
to their facilities,

. facilitating the end-users' choice to switch service providers from
incumbent local exchange carriers to competitive local exchange carriers
such as the Company, and

. requiring access to rights-of-way.

The legislation also is designed to enhance the competitive position of the
competitive local exchange carriers and increase local competition by newer
competitors such as long distance carriers, cable television companies and
public utility companies. Under the Telecommunications Act of 1996, Regional
Bell Operating Companies have the opportunity to provide in-region long
distance services if certain conditions are met and are no longer prohibited
from providing certain cable television services. In addition, the
Telecommunications Act of 1996 eliminates certain restrictions on utility
holding companies, thus clearing the way for them to diversify into
telecommunications services.

The Telecommunications Act of 1996 specifically requires all
telecommunications carriers (including incumbent local exchange carriers and
competitive local exchange carriers (such as the Company)):

. not to prohibit or unduly restrict resale of their services,

. to provide dialing parity and nondiscriminatory access to telephone
numbers, operator services, directory assistance and directory listings,

. to afford access to poles, ducts, conduits and rights-of-way, and

. to establish reciprocal compensation arrangements for the transport and
termination of telecommunications.

69
<PAGE>

It also requires competitive local exchange carriers and incumbent local
exchange carriers to provide interconnection for the transmission and routing
of telephone exchange service and exchange access. It requires incumbent local
exchange carriers to provide such interconnection:

. at any technically feasible point within the incumbent local exchange
carrier's network,

. that is at least equal in quality to that provided by the incumbent
local exchange carrier to itself, its affiliates or any other party to
which the incumbent local exchange carrier provides interconnection, and

. at rates, terms and conditions that are just, reasonable and
nondiscriminatory.

Incumbent local exchange carriers also are required under the new law to
provide nondiscriminatory access to network elements on an unbundled basis at
any technically feasible point, to offer their local telephone services for
resale at wholesale rates, and to facilitate collocation of equipment
necessary for competitors to interconnect with or access the unbundled network
elements.

The Telecommunications Act of 1996 provided for the removal of most
restrictions from AT&T and the Regional Bell Operating Companies resulting
from the consent decree entered in 1982 providing for divestiture of the
Regional Bell Operating Companies from AT&T in 1984. The Telecommunications
Act establishes procedures under which a Regional Bell Operating Company can
enter the market for long distance service between specified areas within its
local service area. The Telecommunications Act of 1996 permitted the Regional
Bell Operating Companies to enter the out-of-region long distance market
immediately upon enactment, and Regional Bell Operating Companies can provide
intra-LATA long distance services. Before the Regional Bell Operating Company
can provide in-region inter-LATA services, it must obtain Federal
Communications Commission approval upon a showing that facilities-based
competition is present in its market, that the Regional Bell Operating Company
has entered into interconnection agreements in the states where it seeks
authority, that the Regional Bell Operating Company has satisfied a 14-point
"checklist" of competitive requirements, and that such entry is in the public
interest. To date, such authority has not been granted, but requests by the
Regional Bell Operating Companies are the subject of pending appeals. The
provision of inter-LATA services by Regional Bell Operating Companies is
expected to reduce the market share of major long distance carriers, and
consequently, may have an adverse effect on the ability of competitive local
exchange carriers to generate access revenues from the long distance carriers.

Federal Communications Commission Rules Implementing the Local Competition
Provisions of the Telecommunications Act of 1996. The Federal Communications
Commission in 1996 established a framework of national rules enabling state
public service commissions and the Federal Communications Commission to begin
implementing many of the local competition provisions of the
Telecommunications Act of 1996. The Federal Communications Commission
prescribed certain minimum points of interconnection necessary to permit
competing carriers to choose the most efficient points at which to
interconnect with the incumbent local exchange carriers' networks. The Federal
Communications Commission also adopted a minimum list of unbundled network
elements that incumbent local exchange carriers must make available to
competitors upon request and a methodology for states to use in establishing
rates for interconnection and the purchase of unbundled network elements. The
Federal Communications Commission also adopted a methodology for states to use
when applying the Telecommunications Act's "avoided cost standard" for
incumbent local exchange carriers to set the prices to be charged to resellers
of their services.

The Federal Communications Commission has authority to establish national
pricing rules for interconnection, unbundled elements and resale services. The
Supreme Court also upheld the Federal Communications Commission's
interpretation of the "pick and choose" provisions, which permit carriers to
obtain favorable provisions in interconnection agreements. However, the
Supreme Court overturned the Federal Communications Commission's rules
regarding what network elements must be unbundled by the Regional Bell
Operating Companies, and remanded to the Federal Communications Commission the
question of what network elements are "necessary" to competing carriers such
as the Company. On November 5, 1999, the Federal

70
<PAGE>

Communications Commission issued an order and proposed rulemaking establishing
the network elements that must be offered by incumbent local exchange carriers
as unbundled network elements. In addition, the Supreme Court's decision
creates some uncertainty regarding the legal status of complaints filed at the
Federal Communications Commission to enforce interconnection agreements. We
cannot assure you that we will be able to maintain interconnection agreements
on terms acceptable to us.

Other Regulation. In general, the Federal Communications Commission's
policies encourage the entry of new competitors in the telecommunications
industry and are designed to prevent anti-competitive practices. Currently,
large incumbent local exchange carriers such as GTE and the Regional Bell
Operating Companies are regulated as "dominant" carriers, while competitive
local exchange carriers such as the Company are considered "nondominant"
carriers. Dominant carriers face more detailed regulatory scrutiny. As a
nondominant carrier, we are subject to relatively minimal Federal
Communications Commission regulation.

. Tariff. We may install and operate facilities for the transmission of
domestic interstate communications without prior Federal Communications
Commission authorization. The Federal Communications Commission requires
us to file tariffs and periodic reports concerning our interstate
circuits and deployment of network facilities, and offer interstate
services on a nondiscriminatory basis, at just and reasonable rates. We
also remain subject to Federal Communications Commission complaint
procedures.

The Federal Communications Commission adopted an order in 1996 (the
"Detariffing Order") which eliminated the requirement that nondominant
interstate carriers maintain tariffs on file with the Federal
Communications Commission for domestic interstate services. The order
provided that, after a nine-month transition period, relationships
between interstate carriers and their customers would be set by
contract. Several parties requested reconsideration and/or filed
appeals of the Detariffing Order. On February 13, 1997, the United
States Court of Appeals for the District of Columbia Circuit stayed
implementation of the Detariffing Order. If the Detariffing Order
becomes effective, nondominant interstate services providers will no
longer be able to rely on the filing of tariffs with the Federal
Communications Commission as a means of providing notice to customers
of prices, terms and conditions under which they offer their interstate
services. If we cancel our Federal Communications Commission tariffs as
a result of the Detariffing Order, we will need to individually
negotiate contract terms with certain of our customers, which could
result in substantial legal and administrative expense.

. Access Charges. The Federal Communications Commission has granted
incumbent local exchange carriers significant flexibility in pricing
their interstate special and switched access services on a specific
central office by central office basis. Under this pricing scheme,
incumbent local exchange carriers may establish pricing zones based on
access traffic density and charge different prices for each zone. We
anticipate that this pricing flexibility will result in incumbent local
exchange carriers lowering their prices in high traffic density areas,
which is where our customers are concentrated. The Federal
Communications Commission adopted an order on August 5, 1999 granting
incumbent local exchange carriers subject to price cap regulation
additional pricing flexibility. These changes will reduce access charges
and will shift charges currently based on minutes to flat-rate, monthly
per line charges. As a result, the aggregate amount of access charges
paid by long distance carriers to access providers in the United States
may decrease.

The order provides certain immediate regulatory relief to incumbent
local exchange carriers subject to price cap regulation and sets a
framework of "triggers" to provide those companies with greater pricing
flexibility to set interstate access rates as competition increases.
The order also initiated a rulemaking to determine whether the Federal
Communications Commission should regulate the access charges of
competitive local exchange carriers. If this increased pricing
flexibility is not effectively monitored by federal regulators, it
could have a material adverse effect on the Company's ability to price
its interstate access services competitively. A May 16, 1999 order,
which was upheld on appeal by the United States Court of Appeals for
the Eighth Circuit, substantially increased the amounts that incumbent
local exchange carriers subject to the Federal Communications
Commission's price cap

71
<PAGE>

rules ("price cap local exchange carriers") recover through monthly
flat-rate charges and substantially decreased the amounts that these
local exchange carriers recover through traffic sensitive (per-minute)
access charges. Several parties appealed the May 16th order.

These decisions are likely to have a significant impact on the operations,
expenses, pricing and revenue of the Company.

Universal Service Reform. The Federal Communications Commission implemented
the provisions of the Telecommunications Act of 1996 relating to the
preservation and advancement of universal telephone service in 1997. The
Federal Communications Commission's universal service principles provide that
universal service support mechanisms and rules should not unfairly advantage
or disadvantage one provider or technology over another. All
telecommunications carriers providing interstate telecommunications services,
including the Company, must contribute to the universal service support fund.
On October 8, 1999, the Federal Communications Commission released an order
implementing changes to its universal service rules to comply with a recent
decision of the Fifth Circuit Court of Appeals. Among other changes, the
Federal Communications Commission revised its rules concerning assessment of
carriers' intrastate and international revenues for universal service
contribution. The contribution factor for November and December 1999 is
5.8995% of interstate and international end-user telecommunications revenues,
which will supersede the fourth quarter contribution factors previously
announced. The Federal Communications Commission narrowed the scope of the
contribution base, removing intrastate end-user telecommunications revenues
from the assessment, consistent with the opinion of the Fifth Circuit Court of
Appeals.

State Regulation

We believe that most, if not all, states in which we operate or propose to
operate require a certification or other authorization to offer intrastate
services. Many of the states in which we operate or intend to operate are in
the process of addressing issues relating to the regulation of competitive
local exchange carriers. We are subject to state tariff filing requirements.

These certifications generally require a showing that the carrier has
adequate financial, managerial and technical resources to offer the proposed
services in a manner consistent with the public interest.

We have obtained intrastate authority for the provision of our dedicated
services and a full range of local switched services and long distance
services. In most states, we are required to file tariffs setting forth the
terms, conditions and prices for services that are classified as intrastate.
We plan to obtain additional state authorities to accommodate our business and
network expansion.

Some states also impose reporting, customer service, and quality
requirements, as well as unbundling and universal service requirements. In
addition, we are subject to the outcome of proceedings held by state utility
commissions to determine state regulatory policies with respect to incumbent
local exchange carrier and competitive local exchange carrier competition,
geographic build-out, mandatory detariffing and other issues relevant to
competitive local exchange carrier operations. Certain states have adopted
state-specific universal service funding obligations.

In addition to obtaining state certifications, we must negotiate terms of
interconnection with the incumbent local exchange carrier before we can begin
providing switched services. Our executed agreements are subject to the
approval of the state commissions. State commissions have approved our
existing agreements. We anticipate state commission approval of our future
interconnection agreements.

We believe that, as the degree of local competition increases, the states
will offer the incumbent local exchange carriers increasing pricing
flexibility. This flexibility may present the incumbent local exchange
carriers with an opportunity to subsidize services that compete with our
services with revenues generated from non-competitive services, thereby
allowing incumbent local exchange carriers to offer competitive services at
prices

72
<PAGE>

below the cost of providing the service. We cannot predict the extent to which
this may occur, but it could have a material adverse effect on our business
and our ability to make payments on the Notes.

We actively participate in various regulatory proceedings before the
states, the outcome of which may establish policies that affect our
competitive and/or economic position in the local and other telecommunications
services markets.

We also may be subject to requirements in certain states to obtain prior
approval for, or notify the state commission of, any transfers of control,
sales of assets, corporate reorganizations, issuances of stock or debt
instruments and related transactions.

Local Government Authorizations. We are required to obtain street use and
construction permits and licenses and/or franchises to install and expand our
fiber optic networks using municipal rights of way. In some municipalities
where we have installed or anticipate constructing networks, we will be
required to pay license or franchise fees based on a percentage of gross
revenues or on a per foot basis, as well as post performance bonds or letters
of credit. We are actively pursuing permits, franchises and other relevant
authorities for use of rights-of-way and utility facilities in a number of
cities.

Legal Proceedings

We are from time to time involved in litigation incidental to the conduct
of our business. There is no pending legal proceeding to which we are a party,
however, which, in the opinion of our management, is likely to have a material
adverse effect on our business, financial condition and results of operations
and our ability to make payments on the notes.

Employees

As of September 30, 1999, we had approximately 840 full time employees.
None of our employees are represented by a labor union or subject to a
collective bargaining agreement, nor have we experienced any work stoppage due
to labor disputes. We believe that our relations with our employees are good.

Properties

We are headquartered in Bedminster, New Jersey in approximately 14,000
square feet of office space, approximately 7,200 of which we lease from Kamine
Development Corp. (an entity controlled by Mr. Kamine, the Company's Chairman
of the Board). The lease with Kamine Development Corp., which expires in
January 2007, provides for a base annual rental of approximately $217,000
(adjusted periodically for changes in the consumer price index), plus
operating expenses.

We also maintain an operations center in an aggregate of approximately
83,000 square feet of leased space in Duluth, Georgia under leases which
expire at various dates from February 2000 through February 2003. We also own
or lease facilities in each of our existing markets for central offices, sales
offices and the location of our switches and related equipment.

We believe that our facilities are in good condition, are suitable for our
operations and that, if needed, suitable alternative space would be readily
available.

Pursuant to provisions contained in both the Company's certificate of
incorporation and a stockholders agreement, Mr. Kamine and the Nassau entities
are currently entitled to elect all of the Directors, three of whom are
nominated by Mr. Kamine (one of whom must be the President and Chief Executive
Officer), three of whom are nominated by Nassau and one of whom is nominated
by agreement of Mr. Kamine, Nassau and either Newcourt Communications Finance
Corporation or the holders of a majority of the outstanding shares of the
Company's Series C Cumulative Convertible Preferred Stock. The number of
Directors which Mr. Kamine is entitled to elect would be reduced to two if the
number of shares owned by him were to fall below two-thirds of the number of
shares of the Company initially issued to him, and to one if the number of
shares owned by him were to fall below one-third of the number of shares
initially issued to him. If his ownership were to fall below 5% of the number
of shares initially issued to him, Mr. Kamine would no longer be entitled to
elect any Directors pursuant to such provisions. Comparable reductions would
be made to the number of Directors which Nassau is entitled to elect if its
ownership were to fall below the specified levels. If a default relating to
payment occurs under the Senior Secured Credit Facility, and continues uncured
for 90 days, the holders of Series C Cumulative Convertible Preferred Stock
(currently Nassau, General Electric Capital Corporation and First Union Corp.)
will be entitled to elect two additional Directors, who will serve until the
default is cured.

Kamine/Besicorp Allegany L.P., an independent power company 50% owned by
corporations which Mr. Kamine owns, filed a voluntary petition to reorganize
its business under Chapter 11 of the Federal Bankruptcy Code in November 1995.
In October 1998, the bankruptcy court confirmed a plan of liquidation for this
entity. The United States Bankruptcy Court for the Northern District of
Indiana appointed a receiver for RimSat, a company which Mr. Sternberg co-
founded and for which he formerly served as Chief Operating Officer, and a
petition for bankruptcy under Chapter 11 of the Federal Bankruptcy Code with
respect to RimSat was filed in 1996. That proceeding is ongoing.

Directors hold office until the next Annual Meeting of stockholders or

Stock Option Grants

The Company was formed as a holding company in September 1997. Prior to the
establishment of the present holding company structure, during 1996 and 1997,
KMC Telecom Inc. (now one of the Company's principal operating subsidiaries)
granted options to purchase shares of its common stock, par value $.01 per
share, to employees, including the Named Executive Officers, and selected
employees of certain affiliated companies owned by Mr. Kamine pursuant to the
1996 Stock Purchase and Option Plan for Key Employees of KMC Telecom Inc. and
Affiliates.

In order to reflect the establishment of the Company's holding company
structure, on June 26, 1998, the Board of Directors of the Company adopted a
new stock option plan, the 1998 Stock Purchase and Option Plan for Key
Employees of KMC Telecom Holdings, Inc. and Affiliates, which authorizes the
grant of options to purchase shares of common stock of the Company. During the
third quarter of 1998, the Company replaced the options to purchase shares of
common stock of KMC Telecom Inc. previously granted under the 1996 KMC Telecom
Inc. plan (including all options shown as granted during 1997 in the preceding
table) with options to purchase shares of common stock of the Company granted
under the 1998 KMC Telecom Holdings, Inc. plan and granted options to
additional employees of the Company, including Mr. Lasher, under the 1998 KMC
Holdings plan. The Company may subsequently grant additional options.

The following table sets forth information regarding grants of options to
purchase shares of common stock made by the Company during 1998 to each of the
Named Executive Officers.

(1) 10% of the aggregate amount of each such option vests on each subsequent
six-month anniversary of the date of grant with options with the lowest
exercise price vesting first followed by others in ascending order of
exercise price. For purposes of vesting, options granted in 1998 under the
1998 KMC Telecom Holdings, Inc. plan to replace options granted in 1996 or
1997 under the 1996 KMC Telecom Inc. plan are deemed to have been granted
on the date of grant of the options which they replace.
(2) There is no active trading market for our common stock. The fair value
shown is based upon management's estimate of the fair value of our common
stock on the date in September 1998 when these options were granted under
the new 1998 KMC Telecom Holdings, Inc. plan. The grant prices were based
on the grant prices of the options previously granted in 1996 and 1997
under the 1996 KMC Telecom Inc. plan which were cancelled and replaced by
the options reflected in this table. The grant prices of the options
granted in

78
<PAGE>

1996 and 1997 had been based on the fair value of the shares of KMC Telecom
Inc. common stock on the respective dates of their grants.
(3) Amounts reported in these columns represent amounts that may be realized
upon exercise of options immediately prior to the expiration of their term
assuming the specified compounded rates of appreciation (0%, 5% and 10%)
on common stock over the term of the options. These assumptions are based
on rules promulgated by the Securities and Exchange Commission and do not
reflect the Company's estimate of future stock price appreciation. Actual
gains, if any, on the stock option exercises and common stock holdings are
dependent on the timing of such exercises and the future value of the
common stock. There can be no assurance that the rates of appreciation
assumed in this table can be achieved or that the amounts reflected will
be received by the option holders.

Employee Plans

KMC Holdings Stock Option Plan. Employees, directors or other persons
having a close relationship with the Company or any of its affiliates are
eligible to participate in the 1998 Stock Purchase and Option Plan for Key
Employees of KMC Telecom Holdings, Inc. and Affiliates. However, neither

The Compensation Committee has the power and authority to designate
recipients of grants under the plan, to determine the terms, conditions and

plan. The exercise price of all incentive stock options granted under the plan
must be at least equal to the fair market value (as defined in the plan) of
Company common stock on the date the options are granted and the exercise
price of all non-qualified options granted under the plan must be at least
equal to 50% of the fair market value of Company common stock on the date the

will be 10 years. Options will become exercisable at such times and in such
installments as the Compensation Committee provides in the terms of each
individual option.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The Company and certain affiliated companies owned by Harold N. Kamine, its
Chairman of the Board, share certain administrative services. The entity which
bears the cost of the service is reimbursed by the other for the other's
proportionate share of such expenses. These shared services do not include the
rent paid by the Company for its headquarters offices to an affiliate of
Mr. Kamine under the lease described below. The Company reimbursed Kamine-
affiliated companies for these shared services an aggregate of approximately
$136,000, for 1998.

From May 1, 1996 through January 29, 1998, Kamine Development Corp., an
affiliate of the Company, was paid a fee at an annual rate of $266,000 as
reimbursement for the services of Mr. Kamine as Chairman of the Board of the
Company. The amount of this fee was reduced to $100,000 per annum as of
January 29, 1998 and it was terminated effective December 31, 1998. The amount
of the fee paid in 1998 is included in the shared services payment described
in the first paragraph above. Effective January 1, 1999, Mr. Kamine became an
employee of the Company and he is currently paid a salary at the rate of
$450,000 per annum for his services as Chairman of the Board.

Effective June 1, 1996, the Company entered into a lease agreement with
Kamine Development Corp. (an entity controlled by Mr. Kamine) pursuant to
which the Company leases its headquarters office in Bedminster, New Jersey.
The lease expires in January 2007. The lease provides for a base annual rental
of approximately $217,000 (adjusted periodically for changes in the consumer
price index), plus operating expenses.

In February, 1998, the Company loaned to Roscoe C. Young II, the Company's
Chief Operating Officer, the principal sum of $350,000. The loan is evidenced
by a promissory note which bears interest at the rate of 6% per annum.
Interest and principal are payable at maturity on February 13, 2003. In June
1998, the Company loaned Mr. Young an additional $110,000, of which $55,000
was repaid within thirty (30) days. The balance of the loan is evidenced by a
promissory note which bears interest at the rate of 6% per annum. It is
payable in December 1999. The largest aggregate amount of loans outstanding to
Mr. Young at any time during 1998 was $460,000. The aggregate amount of loans
outstanding to Mr. Young at September 30, 1999 was $405,000.

In March, 1998, the Company made a bridge loan to Tricia Breckenridge in
the principal amount of $150,000. Ms. Breckenridge is Executive Vice
President--Business Development of the Company. The loan which bore interest
at the rate of 6% per annum, was repaid in full in 1998.

Pursuant to an agreement dated as of January 1, 1999, the Company is
entitled to utilize a Citation III business jet chartered by Bedminster
Aviation LLC, a limited liability company wholly owned by Mr. Kamine, for a
fixed price of $2,600 per hour of flight time. The Citation III will enable up
to eight employees, guests or representatives of the Company to utilize local
airfields and visit multiple cities in which the Company either has an
operating system or is building a system, without the necessity of returning
to commercial hubs such as Atlanta or St. Louis. The Company has agreed to use
its best efforts to utilize the Citation III fifty hours per quarter during
1999. However, the Company is under no obligation to do so and has not
guaranteed any financial arrangements with respect to the aircraft or to
Bedminster Aviation LLC.

On July 1, 1999, the Company acquired all of the membership interests of
KMC Services LLC from Harold N. Kamine, the Chairman of our Board of
Directors, for nominal consideration. KMC Services LLC offers a leasing
program for equipment physically installed at a customer's premises, known as
CPE equipment, for the Company to integrate into its ClearStarsm Advantage
program. As of June 30, 1999, the Company had loaned KMC Services LLC an
aggregate of approximately $709,000. The loan bore interest at the rate of 10%
per annum and was to have been payable December 31, 1999. The acquisition was
accounted for as a combination of entities under common control, and no
changes were made to the historical cost basis of KMC Services LLC's assets.
Accordingly, during the second quarter of 1999, the Company reduced the
carrying value of its $709,000

81
<PAGE>

loan receivable from KMC Services LLC to an amount equal to the value of KMC
Services LLC's net assets at the acquisition date.

Pursuant to agreements entered into in September and October 1997 between
the Company and each of the holders of Series A Cumulative Convertible
Preferred Stock and Series C Cumulative Convertible Preferred Stock, each such
holder has agreed to forego the payment of accumulated dividends on its shares
of Series A Cumulative Convertible Preferred Stock and Series C Cumulative
Convertible Preferred Stock of the Company from the date of such Dividend
Agreement through the date on which such holder disposes of its interest in
the Company; provided, that, upon such disposition, such holder realizes not
less than a ten percent (10%) compound rate of return on its investment for
the period from the date of such Dividend Agreement to the date of such
disposition.

Mr. Kamine, Nassau Capital Partners, L.P., NAS Partners I L.L.C., Newcourt
Communications Finance Corporation, General Electric Capital Corporation,
First Union Corp. (the successor to CoreStates Holdings, Inc.) and First Union
National Bank are parties to a stockholders agreement relating to the Company.
First Union National Bank and First Union Corp. are affiliates of First Union
Capital Markets. Pursuant to this stockholder's agreement and the Company's
certificate of incorporation, Mr. Kamine and Nassau are currently entitled to
elect all of the Company's seven Directors, with each entitled to nominate
three Directors, and the seventh to be nominated by agreement of Mr. Kamine,
Nassau and either Newcourt Communications Finance Corporation or the holders
of a majority of the outstanding shares of the Company's Series C Cumulative
Convertible Preferred Stock. The number of Directors which Mr. Kamine is
entitled to elect would be reduced to two if the number of shares owned by him
were to fall below two-thirds of the number of shares of the Company initially
issued to him, and to one if the number of shares owned by him were to fall
below one-third of the number of shares initially issued to him. If his
ownership were to fall below 5% of the number of shares initially issued to
him, Mr. Kamine would no longer be entitled to elect any Directors pursuant to
such provisions. Comparable reductions would be made to the number of
Directors which Nassau is entitled to elect if its ownership were to fall
below the specified levels.

Newcourt Commercial Finance Corporation (an affiliate of Newcourt Capital,
Inc.) has provided financing for the Company as one of the lenders under the
Senior Secured Credit Facility. Pursuant to the Senior Secured Credit
Facility, the lenders have agreed to make available, subject to certain
conditions, up to a total of $250.0 million for construction and development
of the Company's 23 existing networks. The Company paid Newcourt Capital, Inc.
and its affiliates an aggregate of $1,717,000 in fees, discounts and
commissions during the year ended December 31, 1998.

Upon closing of its offering of Senior Discount Notes in January 1998, the
Company paid Nassau approximately $600,000 for dividend arrearages on its
shares of Series A Cumulative Convertible Preferred Stock of KMC Telecom Inc.
which Nassau had exchanged for its shares of Series A Cumulative Convertible
Preferred Stock of the Company.

Pursuant to an agreement among the Company, Mr. Kamine and Nassau, for 1998
Nassau received $100,000 as a financial advisory fee and as compensation for
the Nassau designees who served on the Board of Directors of the Company.
Nassau will be paid $450,000 as a financial advisory fee for 1999.

beneficially owned by a person and the percentage ownership of that
person, shares subject to options, warrants and convertible securities
held by that person that are currently exercisable or exercisable within
60 days of September 30, 1999 are deemed outstanding. Such shares,
however, are not deemed outstanding for the purposes of computing the
percentage ownership of any other person. Except as indicated in the
footnotes to this table, each shareholder named in the table has sole
voting and investment power with respect to the shares set forth opposite
such shareholder's name.

(8) Messrs. Quigley and Hack, Directors of the Company, are members of Nassau
Capital L.L.C., the general partner of Nassau; accordingly Messrs. Quigley
and Hack may be deemed to be beneficial owners of such shares and for
purposes of this table they are included. Messrs. Quigley and Hack
disclaim beneficial ownership of all such shares within the meaning of
Rule 13d-3 under the Exchange Act. Messrs. Quigley and Hack are also
members of NAS Partners I, L.L.C.; accordingly Messrs. Quigley and Hack
may be deemed to be beneficial owners of such shares and for purposes of
this table they are included. Messrs. Quigley and Hack disclaim beneficial
ownership of all such shares within the meaning of Rule 13d-3 under the
Exchange Act.
(9) All of the shares indicated as owned by Mr. Stewart are owned directly or
indirectly by Nassau and are included because of Mr. Stewart's affiliation
with Nassau. Mr. Stewart is also a member of NAS Partners I, L.L.C.;
accordingly, Mr. Stewart may be deemed to be the beneficial owner of such
shares and for purposes of this table they are included. Mr. Stewart
disclaims beneficial ownership of all of these shares within the meaning
of Rule 13d-3 under the Exchange Act.

Stockholders Agreement. The Amended and Restated Stockholders Agreement
dated as of October 31, 1997 restricts the ability of the parties to that
agreement to transfer shares in the Company to persons not affiliated with or
related to such parties. Pursuant to this stockholders agreement and the
Company's certificate of incorporation, Mr. Kamine and Nassau are currently
entitled to elect all of the Directors, three of whom are nominated by
Mr. Kamine (one of whom must be the President and Chief Executive Officer),
three of whom are nominated by Nassau and one of whom is nominated by agreement
of Mr. Kamine, Nassau and either Newcourt Communications Finance Corporation or
the holders of a majority of the outstanding shares of the Company's Series C
Cumulative Convertible Preferred Stock. The number of Directors which Mr.
Kamine is entitled to elect would be reduced to two if the number of shares
owned by him were to fall below two-thirds of the number of shares of the
Company initially issued to him, and to one if the number of shares owned by
him were to fall below one-third of the number of shares initially issued to
him. If his ownership were to fall below 5% of the number of shares initially
issued to him, Mr. Kamine would no longer be entitled to elect any Directors
pursuant to such provisions. Comparable reductions would be made to the number
of Directors which Nassau is entitled to elect if its ownership were to fall
below the specified levels. If a default relating to payment occurs under the
Senior Secured Credit Facility, and continues uncured for 90 days, the holders
of Series C Cumulative Convertible Preferred Stock (currently Nassau, General
Electric Capital Corporation and First Union Corp.) will be entitled to elect
two additional Directors, who will serve until the default is cured.

Each of Nassau, First Union Corp., General Electric Capital Corporation and
Newcourt Communications Finance Corporation has a "put right" entitling it to
have the Company repurchase its shares for the fair market value of such
shares if no Liquidity Event (defined as (i) an initial public offering with
gross proceeds of at least $40.0 million, (ii) the sale of substantially all
of the stock or assets of the Company or (iii) the merger or consolidation of
the Company with one or more other corporations) has taken place by the later
of (x) October 22, 2003 or (y) 90 days after the final maturity date of the
notes. First Union Corp., General Electric Capital Corporation and Newcourt
Communications Finance Corporation may not exercise such put rights unless
Nassau has exercised its put right. The indenture applicable to the notes, the
indenture applicable to our Senior Discount Notes and the terms of our other
indebtedness will limit our ability to repurchase such shares.

<PAGE>

Certain of the current stockholders have demand registration rights with
respect to their shares of our common stock commencing on the earlier of June
5, 2000 (in the case of Mr. Kamine or Nassau) and the date on which the
Company completes an initial public offering of common stock (and any related
holdback period expires). Each of the holders of registrable securities also
has certain piggyback registration rights. The parties to the stockholders
agreement have agreed not to effect any public sale or distribution of common
stock of the Company, or securities convertible into such common stock, within
180 days of the effective date of any demand or piggyback registration.

DESCRIPTION OF CERTAIN INDEBTEDNESS AND PREFERRED STOCK

Senior Discount Notes

On January 29, 1998 we issued $460.8 million aggregate principal amount at
maturity of 12 1/2% Senior Discount Notes due 2008. On August 11, 1998, we
exchanged those notes for $460.8 million aggregate principal amount at
maturity of notes that had been registered under the Securities Act of 1933.
The terms of the Senior Discount Notes are substantially similar to those of
the notes, except that the notes pay cash interest, mature after the Senior
Discount Notes and have a different interest rate.

The Senior Discount Notes are unsecured, unsubordinated obligations of the
Company and were sold at a substantial discount from their principal amount at
maturity. We are not required to make any payment of interest on the Senior
Discount Notes prior to August 15, 2003. The Senior Discount Notes will fully
accrete to face value on February 15, 2003. From and after February 15, 2003,
the Senior Discount Notes will bear interest, which will be payable in cash,
at the rate of 12 1/2% per annum on February 15 and August 15 of each year,
commencing August 15, 2003.

The indenture pursuant to which our Senior Discount Notes were issued
contains certain covenants that, among other things, limit our ability to
incur additional indebtedness, pay dividends or make certain other
distributions, enter into transactions with stockholders and affiliates and
create liens on our assets. We have the option to redeem the Senior Discount
Notes at any time after February 15, 2003, at redemption prices ranging from
100% to 106.25% of their principal amount at maturity, plus any accrued and
unpaid interest. Before April 15, 2000, we may also redeem up to 35% of the
aggregate principal amount at maturity of the Senior Discount Notes with the
proceeds from sales of our common equity at a redemption price equal to 112.5%
of their accreted value on such date. Upon a change of control, we are
required to make an offer to purchase the Senior Discount Notes at a purchase
price equal to 101% of their accreted value.

Senior Secured Credit Facility

Under our Senior Secured Credit Facility, Newcourt Commercial Finance
Corporation, First Union National Bank, General Electric Capital Corporation
and Canadian Imperial Bank of Commerce are the lead lenders for a $250.0
million senior secured credit facility for certain of our operating
subsidiaries, KMC Telecom Inc., KMC Telecom II, Inc., their respective wholly-
owned limited liability companies, and KMC Telecom of Virginia, Inc., which
own our existing 23 systems. Affiliates of certain of the placement agents
with respect to the original notes are lenders under this facility. Initially,
the proceeds of loans under this senior secured credit facility may be used
for the construction of fiber optic telecommunications networks, and for the
payment of transaction fees and expenses, subject to certain conditions. Once
the borrowers satisfy certain financial tests the proceeds of loans may also
be used by these subsidiaries for working capital and other general corporate
purposes, subject to certain conditions. The Senior Secured Credit Facility
includes a $175.0 million eight year revolving loan and a $75.0 million eight
and one-half year term loan.

We have unconditionally guaranteed the repayment of the Senior Secured
Credit Facility when such repayment is due. We have also agreed to pay all
amounts outstanding under the Senior Secured Credit Facility, on demand, upon
the occurrence and during the continuation of any event of default. We have
pledged the shares of KMC Telecom Inc. and KMC Telecom II, Inc. to secure our
obligations under the guaranty. KMC Telecom Inc. and KMC Telecom II, Inc.
have, in turn, pledged their ownership interests in their subsidiaries, as
well as all of their other assets and the assets of their subsidiaries to
Newcourt Commercial Finance Corporation.

The Senior Secured Credit Facility contains a number of negative covenants
that, among other things, restrict the ability of the borrowers thereunder to
sell or lease assets, redeem stock, pay dividends or make any other payments
(including payments of principal or interest on loans) to us or incur
additional indebtedness or act as guarantor for the debt of any persons,
subject to certain conditions.

87
<PAGE>

The borrowers are required to comply with certain financial tests and
maintain certain financial ratios, including, among others, a ratio of total
debt to contributed capital, certain minimum revenues, maximum EBITDA losses
and minimum EBITDA, maximum capital expenditures and minimum access lines. The
Senior Secured Credit Facility also includes customary events of default,
including, among others, a cross-default to other material indebtedness,
bankruptcy, breach of representations and warranties, a material adverse
change, and the occurrence of a change of control.

Lucent Facility

On February 4, 1999, our subsidiary, KMC Telecom III, Inc. and its
subsidiary limited liability company, which will own the 14 additional
networks currently planned for completion by the end of the first half of
2000, entered into a secured credit facility with Lucent Technologies Inc. The
Lucent Facility provides for borrowings by KMC Telecom III, Inc. and its
subsidiary to fund certain equipment acquisition costs and related expenses,
and will mature on January 1, 2007. The Lucent Facility provides for an
aggregate commitment of up to $600.0 million available as follows: (i) $125.0
million was immediately available to purchase Lucent products, (ii) $125.0
million becomes available upon the borrowers' receipt of an additional $35.0
million of funded equity or qualified intercompany loans, and (iii) up to an
additional $350.0 million becomes available upon (A) Lucent's selling
commitments to make loans such that Lucent's aggregate commitment does not
exceed $250.0 million at any one time, (B) the borrowers' complying with
certain financial covenants, (C) the borrowers' delivery of a business plan to
Lucent and (D) the Company or KMC Telecom III Holdings, Inc. raising and
contributing at least $300.0 million in high yield debt or equity to KMC
Telecom III, Inc.

We have guaranteed up to $250.0 million of the Lucent Facility, and KMC
Telecom III Holdings, Inc. has agreed to pay all amounts outstanding under the
Lucent Facility, on demand, upon the occurrence and during the continuation of
any event of default. KMC Telecom III Holdings, Inc. has pledged the shares of
KMC Telecom III, Inc., and KMC Telecom III, Inc. has pledged its ownership
interests in its subsidiary limited liability company, to Lucent. In addition,
KMC Telecom III, Inc. and its subsidiary have each granted a security interest
in all of their assets to Lucent.

The Lucent Facility contains a number of negative covenants that, among
other things, restrict the ability of the borrowers to sell or lease assets,
redeem stock, pay dividends or make any other payments (including payments of
principal or interest on loans) to us or incur additional indebtedness or act
as guarantor for the debt of any person.

The borrowers are required to comply with certain financial tests and
maintain certain financial ratios, including, among others, a ratio of total
debt to contributed capital, certain minimum revenues, maximum EBITDA losses
and minimum EBITDA, maximum capital expenditures and minimum access lines. The
Lucent Facility also includes customary events of default, including, among
others, a cross-default to other material indebtedness, bankruptcy, breach of
representations and warranties, a material adverse change, and the occurrence
of a change of control.

Preferred Stock

Our board of directors has authority, subject to certain consent rights of
holders of preferred stock, to authorize the issuance of classes of preferred
stock from time to time in one or more series, with such designations,
preferences and relative rights within the limits prescribed by the Delaware
General Corporation Law, as may be determined by the board of directors. The
designations, preferences and rights of the existing series of preferred stock
are set forth below:

Series A Cumulative Convertible Preferred Stock. There are 123,800 shares
of Series A Cumulative Convertible Preferred Stock authorized and outstanding.
Series A Preferred Stock has a liquidation preference of $100 per share and an
annual dividend equal to 7.0% of the liquidation preference, payable
quarterly, when and if declared by the Board of Directors out of funds legally
available therefor. Unpaid dividends accumulate and

88
<PAGE>

the unpaid amount increases at the annual rate of 7.0%, compounded quarterly.
All accumulated but unpaid dividends will be paid upon the occurrence of a
Realization Event (defined as (i) an initial public offering with gross
proceeds of at least $40.0 million or (ii) sale of substantially all the
assets or stock of the Company or the merger or consolidation of the Company
into one or more other corporations). Pursuant to an agreement among Nassau,
NAS and the Company dated September 22, 1997, Nassau and NAS have agreed to
forego the payment of dividends from September 22, 1997 through the date on
which Nassau or NAS disposes of its interest in the Company; provided that at
the time of such disposition Nassau or NAS, as the case may be, has received
not less than a 10% annual compound rate of return during the period it held
the Series A Preferred Stock.

Series A Preferred Stock is convertible into common stock at a conversion
price equal to $20.63 per share of common stock, subject to adjustment upon
the occurrence of certain events. Holders of Series A Preferred Stock may
convert all or part of such shares to common stock at any time and from time
to time. Upon conversion, the holders are entitled to receive a cash payment
of the accumulated but unpaid dividends; provided, however, that the Company
may substitute common shares having a fair market value equal to the amount of
such cash payment if the conversion occurs before a Realization Event. Series
A Preferred Stock will automatically convert into common stock upon the
occurrence of a Qualified Public Offering (defined as the first sale of common
stock pursuant to a registration statement filed under the Securities Act in
which the Company receives gross proceeds of at least $40.0 million, provided
that the per share price at which such shares are sold in such offering is at
least four times the conversion price of the Series A Preferred Stock).

The holders of Series A Preferred Stock, except as otherwise provided in
the Company's certificate of incorporation, are entitled to vote on all
matters voted on by holders of common stock. Each share of Series A Preferred
Stock is entitled to a number of votes equal to the number of shares of common
stock into which such share is convertible. Without the prior consent of two-
thirds of the shares of Series A Preferred Stock, among other things, the
Company may not increase the number of shares of preferred stock (of whatever
series) authorized for issuance, or declare or pay any dividends on shares of
common stock or other junior shares.

Series C Cumulative Convertible Preferred Stock. There are 350,000 shares
of Series C Cumulative Convertible Preferred Stock authorized of which 175,000
shares are outstanding. Series C Preferred Stock has a liquidation preference
of $100 per share and an annual dividend equal to 7.0% of the liquidation
preference, payable quarterly, when and if declared by the Board of Directors
out of funds legally available therefor. Unpaid dividends accumulate and the
unpaid amount increases at the annual rate of 7.0%, compounded quarterly. All
accumulated but unpaid dividends will be paid upon the occurrence of a
Realization Event. Pursuant to the Purchase Agreement among the Company, GECC,
First Union Corp. and Nassau dated as of October 31, 1997, each current holder
of Series C Preferred Stock has agreed to forego the payment of dividends that
accumulate during the period from October 31, 1997 through the date on which
such holder disposes of its interest in the Company; provided that at the time
of such disposition it has received not less than a 10% annual compound rate
of return during such period.

Series C Preferred Stock is convertible into common stock at a conversion
price equal to (i) from the date of initial issuance to but excluding the date
which is 30 months after the date of such initial issuance, $52.50 per share
of common stock; provided, however, that if a Realization Event occurs during
such 30-month period the conversion price will be equal to a fraction the
numerator of which is (A) the consideration per share of common stock (on a
fully diluted basis) received in connection with such Realization Event, and
the denominator of which is (B) 1.30 raised to a number equal to the number of
years (or fraction thereof) from the date of initial issuance of the Series C
Preferred Stock until the date of such Realization Event, but in no case
greater than $52.50 nor less than $42.18 per share of common stock and (ii)
from and after the date which is 30 months after the date of initial issuance,
$42.18, subject to adjustment upon the happening of certain events. Holders of
Series C Preferred Stock may convert all or part of such shares to common
stock at any time and from time to time. Upon conversion, the holders are
entitled to receive a cash payment of the accumulated but unpaid dividends;
provided, however, that the Company may substitute common shares having a fair
market value equal to the amount of such cash payment if the conversion occurs
before a Realization Event. Series C Preferred Stock will automatically
convert into common stock upon the occurrence of a Qualified Public Offering.

89
<PAGE>

The holders of Series C Preferred Stock, except as otherwise provided in
the Company's certificate of incorporation, are entitled to vote on all
matters voted on by holders of common stock. Each share of Series C Preferred
Stock is entitled to a number of votes equal to the number of shares of common
stock into which such share is convertible. Without the prior consent of two-
thirds of the shares of Series C Preferred Stock, among other things, the
Company may not increase the number of shares of preferred stock (of whatever
series) authorized for issuance, or declare or pay any dividends on shares of
common stock or other junior shares.

The Series C Preferred Stock is subject to redemption at the option of the
Company, in whole but not in part, in connection with an "Acquisition Event."
An Acquisition Event is defined to mean any merger or consolidation of the
Company with any other company, person or entity, whether or not the Company
is the surviving entity, as a result of which the holders of the Company's
common stock (determined on a fully diluted basis) will hold less than a
majority of the outstanding shares of common stock or other equity interest of
the company, person or entity resulting from such transaction, or any parent
of such entity.

Series D Cumulative Convertible Preferred Stock. There are 25,000 shares of
Series D Cumulative Convertible Preferred Stock authorized, none of which are
currently outstanding. Series D Preferred Stock has a liquidation preference
of $100 per share and an annual dividend equal to 7.0% of the liquidation
preference, payable quarterly, when and if declared by the Board of Directors
out of funds legally available therefor. Unpaid dividends accumulate and the
unpaid amount increases at the annual rate of 7.0%, compounded quarterly. All
accumulated but unpaid dividends will be paid upon the occurrence of a
Realization Event.

Series D Preferred Stock is convertible at any time into an equal number of
shares of Series C Preferred Stock. In addition, Series D Preferred Stock is
convertible into common stock at a conversion price equal to (i) from the date
of initial issuance to but excluding the date which is 30 months after the
date of such initial issuance, $52.50 per share of common stock; provided,
however, that if a Realization Event occurs during such 30-month period the
conversion price will be equal to a fraction the numerator of which is (A) the
consideration per share of common stock (on a fully diluted basis) received in
connection with such Realization Event, and the denominator of which is (B)
1.30 raised to a number equal to the number of years (or fraction thereof)
from the date of initial issuance of the Series D Preferred Stock until the
date of such Realization Event, but in no case greater than $52.50 nor less
than $42.18 per share of common stock and (ii) from and after the date which
is 30 months after the date of initial issuance, $42.18, subject to adjustment
upon the happening of certain events. Holders of Series D Preferred Stock may
convert all or part of such shares to common stock at any time and from time
to time. Upon conversion, the holders are entitled to receive a cash payment
of the accumulated but unpaid dividends; provided, however, that the Company
may substitute common shares having a fair market value equal to the amount of
such cash payment if the conversion occurs before a Realization Event. Series
D Preferred Stock will automatically convert into common stock upon the
occurrence of a Qualified Public Offering.

The holders of Series D Preferred Stock have voting rights in certain
circumstances. The outstanding shares of Series D Preferred Stock are subject
to redemption at the option of the Company, in whole but not in part, in
connection with an Acquisition Event.

Series E Senior Redeemable, Exchangeable, PIK Preferred Stock. There are
575,000 shares of Series E Senior Redeemable, Exchangeable, PIK Preferred
Stock authorized, of which 65,004 are currently outstanding. Series E
Preferred Stock has a liquidation preference of $1,000 per share and an annual
dividend equal to 14.5% of the liquidation preference, payable quarterly. On
or before January 15, 2004, the Company may pay dividends in cash or in
additional fully-paid and nonassessable shares of Series E Preferred Stock.
After January 15, 2004, dividends must be paid in cash, subject to certain
conditions. Unpaid dividends accrue at the dividend rate of the Series E
Preferred Stock, compounded quarterly.

90
<PAGE>

redeem the Series E Preferred Stock, in whole or in part, at any time after
April 15, 2004, at redemption prices beginning at 110% and declining to 100%
of the liquidation preference of the Series E Preferred Stock, plus all
accrued and unpaid dividends to the date of redemption.

Before April 15, 2002, we may also redeem up to 35% of the aggregate
liquidation preference of Series E Preferred Stock with the proceeds of one or
more sales of our capital stock at a redemption price equal to 110% of the
liquidation preference on the redemption date.

Upon a change of control, we are required to make an offer to repurchase
the Series E Preferred Stock for cash at a purchase price of 101% of the
liquidation preference thereof, together with all accumulated and unpaid
dividends to the date of purchase.

The Series E Preferred Stock is not convertible. The Company may, at the
sole option of the Board of Directors (subject to the legal availability of
funds therefor), exchange all, but not less than all, of the Series E
Preferred Stock then outstanding, including any shares of Series E Preferred
Stock issued as payment for dividends, for a new series of subordinated
debentures (the "Exchange Debentures") issued pursuant to an exchange
debenture indenture. The holders of Series E Preferred Stock are entitled to
receive on the date of any such exchange, Exchange Debentures having an
aggregate principal amount equal to (i) the total of the liquidation
preference for each share of Series E Preferred Stock exchanged, plus (ii) an
amount equal to all accrued but unpaid dividends payable on such share. In the
event such exchange would result in the issuance of Exchange Debentures in a
principal amount less than $1,000 or which is not an integral multiple of
$1,000 (such principal amount less than $1,000 or the difference between such
principal amount and the highest integral of $1,000 which is less than such
principal amount, as the case may be, is hereinafter referred to as the
"Fractional Principal Amount"), the Company may, subject to any restrictions
in the terms of the then-existing Indebtedness of the Company, at the option
of the Board of Directors, pay cash to each holder of Series E Preferred Stock
in lieu of Fractional Principal Amounts of Exchange Debentures otherwise
issuable upon exchange of the Series E Preferred Stock.

Series F Senior Redeemable, Exchangeable, PIK Preferred Stock. There are
55,000 shares of Series F Senior Redeemable, Exchangeable, PIK Preferred Stock
authorized, 44,177 shares of which are currently outstanding. Series F
Preferred Stock has a liquidation preference of $1,000 per share and an annual
dividend equal to 14.5% of the liquidation preference, payable quarterly. On
or before January 15, 2004, the Company may pay dividends in cash or in
additional fully-paid and nonassessable shares of Series F Preferred Stock.
After January 15, 2004, dividends must be paid in cash, subject to certain
conditions. Unpaid dividends accrue at the dividend rate of the Series F
Preferred Stock, compounded quarterly.

We have the option to redeem the Series F Preferred Stock at any time, in
whole or in part, at a redemption price equal to 110% of the liquidation
preference on the redemption date, plus all accrued and unpaid dividends to
the date of redemption. If we fail to redeem all shares of Series F Preferred
Stock prior to the date that is the earlier of (i) the date that is sixty days
after the date on which we close an underwritten primary offering of at least
$200.0 million of our common stock pursuant to an effective registration
statement under the Securities Act or (ii) February 4, 2001, we must issue to
certain holders of Series E Preferred Stock and Series F Preferred Stock,
warrants to purchase up to an aggregate of 5.0% of the common stock of the
Company outstanding as of the date the Series F Preferred Stock was issued.
The number of warrants to be issued will be reduced pro rata based on the
number of shares of Series F Preferred Stock redeemed.

Upon a change of control, we are required to make an offer to repurchase
the Series F Preferred Stock for cash at a purchase price of 101% of the
liquidation preference thereof, together with all accumulated and unpaid
dividends to the date of purchase.

Upon the earlier of (i) the date that is sixty days after the date on which
the Company closes an underwritten primary offering of at least $200.0 million
of its common stock, pursuant to an effective registration statement under the
Securities Act or (ii) February 4, 2001, any outstanding Series F Preferred
Stock will automatically

91
<PAGE>

convert into the right to receive Series E Preferred Stock, on a one for one
basis. The Company may, at the sole option of the Board of Directors (subject
to the legal availability of funds therefor), exchange all, but not less than
all, of the Series F Preferred Stock then outstanding, including any shares of
Series F Preferred Stock issued as payment for dividends, for Exchange
Debentures. The holders of Series F Preferred Stock are entitled to receive on
the date of any such exchange, Exchange Debentures having an aggregate
principal amount equal to (i) the total of the liquidation preference for each
share of Series F Preferred Stock exchanged, plus (ii) an amount equal to all
accrued but unpaid dividends payable on such share. The Company may, subject
to any restrictions in the terms of the then-existing Indebtedness of the
Company, at the option of the Board of Directors, pay cash to each holder of
Series F Preferred Stock in lieu of Fractional Principal Amounts of Exchange
Debentures otherwise issuable upon exchange of the Series F Preferred Stock.

DESCRIPTION OF THE EXCHANGE NOTES

The original notes were, and the exchange notes (collectively, the "notes")
will be, issued under the Indenture, dated as of May 24, 1999, between us and
The Chase Manhattan Bank (the "Trustee"). A copy of the Indenture has been
filed as an Exhibit to the Registration Statement of which this prospectus is
a part. The following summary of certain provisions of the Indenture does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, all of the provisions of the Indenture, including the
definitions of certain terms therein and those terms made a part thereof by
the Trust Indenture Act of 1939, as amended. Whenever particular defined terms
of the Indenture not otherwise defined herein are referred to, such defined
terms are incorporated herein by reference. For definitions of certain
capitalized terms used in the following summary, see "--Certain Definitions."

General

The form and terms of the exchange notes are the same as the form and terms
of the original notes, except that the exchange notes have been registered
under the Securities Act and therefore will not bear legends restricting the
transfer thereof. The exchange notes will be unsubordinated, unsecured (except
as described in "--Security"), senior obligations of the Company, initially
limited to $275,000,000 aggregate principal amount. Subject to the covenants
described below under "--Covenants" and applicable law, the Company may issue
additional notes ("Additional Notes") under the Indenture. The original notes,
the exchange notes and any Additional Notes subsequently issued would be
treated as a single class for all purposes under the Indenture.

The exchange notes will initially bear interest at 13 1/2% per annum from
May 24, 1999 or from the most recent Interest Payment Date to which interest
has been paid. We will pay interest on the notes semiannually on May 15 and
November 15 of each year, beginning November 15, 1999. We will pay interest to
holders of record at the close of business on the May 1 or November 1
immediately preceding the Interest Payment Date. Interest is computed on a
360-day year of twelve 30-day months.

If you give us wire transfer instructions, we will pay all principal,
premium and interest on your notes in accordance with your instructions. If
you do not give us wire transfer instructions, we will make payments of
principal, premium and interest at the office or agency of the paying agent,
which will initially be the Trustee, unless we elect to make interest payments
by check mailed to you.

We will issue the exchange notes only in fully registered form, without
coupons, in denominations of $1,000 of principal amount and any integral
multiple thereof. See "--Book-Entry; Delivery and Form." We will not require
the payment of any service charge for any registration of transfer or exchange
of notes, but we may require payment of a sum sufficient to cover any transfer
tax or other similar governmental charge payable in connection with any
transfer or exchange.

Optional Redemption

We may redeem the notes, in whole or in part, at any time on or after May
15, 2004 at the following Redemption Prices (expressed in percentages of
principal amount), plus accrued and unpaid interest, if any, to the Redemption
Date, if redeemed during the 12-month period commencing May 15, of the years
set forth below:

<TABLE>
<CAPTION>
Year Redemption Price
---- ----------------
<S> <C>
2004..................................................... 106.750%
2005..................................................... 104.500%
2006..................................................... 102.250%
2007 and thereafter...................................... 100.000%
</TABLE>

In addition, at any time prior to May 15, 2002, we may redeem up to 35% of
the principal amount of the notes with the Net Cash Proceeds of one or more
public or private Equity Offerings at a Redemption Price

93
<PAGE>

(expressed as a percentage of principal amount) of 113.500%, plus accrued and
unpaid interest to the Redemption Date; provided that at least 65% of the
aggregate principal amount of notes originally issued remains outstanding
after each such redemption and notice of any such redemption is mailed within
60 days after the applicable Equity Offering.

We will give not less than 30 days' nor more than 60 days' notice of any
redemption. If less than all of the notes are to be redeemed, selection of the
notes for redemption will be made by the Trustee:

. in compliance with the requirements of the principal national securities
exchange, if any, on which the notes are listed, or

. if the notes are not listed on a national securities exchange, by lot or
by such other method as the Trustee in its sole discretion shall deem to
be fair and appropriate.

However, we will not redeem in part any note of $1,000 in principal amount or
less. If we redeem any note in part only, the notice of redemption relating to
such note will state the portion of the principal amount of such note to be
redeemed. We will issue a new note in principal amount equal to the unredeemed
portion of the original note in the name of the holder thereof upon
cancellation of the original note.

Sinking Fund

There will be no sinking fund payment on the notes.

Registration Rights

We agreed with the initial purchasers, for the benefit of the holders of
the original notes, that we would use our reasonable best efforts, at our
cost, to consummate this exchange offer. In satisfaction of this obligation,
we are hereby offering the exchange notes in return for surrender of the
original notes. It is intended by us that the exchange offer will satisfy
these registration rights, which will terminate upon the consummation of the
exchange offer. For each original note surrendered to us pursuant to the
exchange offer, the Holder will receive an exchange note of equal principal
amount. Interest on each exchange note will accrue from the last Interest
Payment Date on which interest was paid on the notes so surrendered or, if no
interest has been paid on such notes, from the Closing Date. Interest on each
exchange note will be calculated and paid in the same manner as interest on
the original notes so surrendered and exchanged therefor.

Security

On the Closing Date, we utilized approximately $104.1 million of the
proceeds from the offering of the original notes to purchase the Pledged
Securities in an amount sufficient, upon receipt of scheduled interest and
principal payments on such securities, to provide for payment in full of the
first six scheduled interest payments due on the notes and pledged the Pledged
Securities to the Trustee for the benefit of the Holders.

The Pledged Securities will be held by the Trustee in the Pledge Account.
Pursuant to the Pledge Agreement, immediately prior to an Interest Payment
Date on the notes, the Company may either deposit with the Trustee from funds
otherwise available to the Company cash sufficient to pay the interest
scheduled to be paid on such date or the Company may direct the Trustee to
release from the Pledge Account proceeds sufficient to pay interest then due
on the notes. In the event that the Company exercises the former option, the
Company may thereafter direct the Trustee to release to the Company proceeds
or Pledged Securities from the Pledge Account in like amount. A failure to pay
interest on the notes in a timely manner through the first six scheduled
interest payment dates will constitute an immediate Event of Default under the
Indenture, with no grace or cure period.

Interest earned on the Pledged Securities will be added to the Pledge
Account. In the event that the funds or Pledged Securities held in the Pledge
Account exceed the amount sufficient to provide for payment in full of the

94
<PAGE>

first six scheduled interest payments due on the notes, the Trustee will be
permitted to release any such excess amount to the Company. The notes will be
secured by the Pledged Securities and the Pledge Account and, accordingly, the
Pledged Securities and the Pledge Account will also secure repayment of the
principal amount of the notes to the extent of such security.

Under the Pledge Agreement, assuming that the Company makes the first six
scheduled interest payments on the notes in a timely manner, the Trustee will
release all of the remaining Pledged Securities in the Pledge Account to the
Company and thereafter the notes will be unsecured.

Ranking

The exchange notes will be unsubordinated, unsecured (except as described
in "--Security") senior indebtedness of the Company, ranking equal in right of
payment with all of our existing and future unsubordinated, unsecured
indebtedness (including the Senior Discount Notes). The exchange notes will be
senior in right of payment to any of our future subordinated indebtedness. As
of September 30, 1999, including the notes, the Company (on an unconsolidated
basis) had $567.2 million of indebtedness, excluding current liabilities, none
of which was secured. However, we are a holding company and the exchange notes
will be effectively subordinated to all existing and future indebtedness
(including the Senior Secured Credit Facility and Lucent Facility) and
liabilities (including trade payables and any subordinated indebtedness) of
our subsidiaries. As of September 30, 1999, our subsidiaries had approximately
$172.3 million of liabilities (excluding intercompany payables).

Book-Entry; Delivery and Form

Except as described below, we will initially issue the exchange notes in
the form of one or more fully registered exchange notes in global form (each,
a "Global Note"). We will deposit each Global Note on the date of the closing
of the exchange offer with, or on behalf of, the depository or an agent of the
depository in New York, New York and register the exchange notes in the name
of the depository or its nominee (the "Global Note Registered Owner") or will
leave such notes in the custody of the Trustee. Except as set forth below, the
Global Note may be transferred, in whole and not in part, only to another
nominee of the depository or to a successor of the depository or its nominee.

Exchange notes issued in exchange for other original notes will be issued
in registered, certificated form without interest coupons.

We are providing you with the following description of the operations and
procedures of DTC, Euroclear and Cedel solely as a matter of convenience.
These operations and procedures are solely within the control of the
respective settlement systems and are subject to change by them from time to
time. We take no responsibility for these operations and procedures and urge
you to contact the system or their participants directly to discuss these
matters.

The depository has advised us that it is a limited-purpose trust company
created to hold securities for its participating organizations (collectively,
the "Participants") and to facilitate the clearance and settlement of
transactions in those securities between Participants through electronic book-
entry changes in the accounts of its Participants. The Participants include
securities brokers and dealers, banks, trust companies, clearing corporations
and certain other organizations. Access to the depository's system is also
available to other entities such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly (collectively, the "Indirect
Participants"). Persons who are not Participants or Indirect Participants may
beneficially own securities held by or on behalf of the depository only
through Participants or Indirect Participants. The ownership interests and
transfer of ownership interests of such persons held by or on behalf of the
depository are recorded on the records of the Participants and Indirect
Participants.

95
<PAGE>

The depository has also advised us that pursuant to procedures established
by it, (i) upon deposit of the Global Note, the depository will credit the
accounts of its Participants with portions of the principal amount of the
Global Note representing the exchange notes issued in exchange for the
original notes that each such Participant has instructed the depository to
surrender for exchange and (ii) ownership of such interests in the Global Note
will be shown on, and the transfer of ownership thereof will be effected only
through, records maintained by the depository (with respect to the
Participants) or by the Participants and the Indirect Participants (with
respect to other owners of beneficial interests in the Global Note).

Under the terms of the Indenture, the Company and the Trustee will treat
the persons in whose names the exchange notes, including the Global Note, are
registered as the owners thereof for the purpose of receiving payments in
respect of the principal of and premium, if any, and interest on any exchange
notes and for any and all other purposes whatsoever. Payments on any exchange
notes registered in the name of the Global Note Registered Owner will be
payable by the Trustee to the Global Note Registered Owner in its capacity as
the registered holder under the Indenture. Consequently, neither us, the
Trustee nor any of our agents or the Trustee has or will have any
responsibility or liability for:

. any aspect of the depository's records or the records of any Participant
or Indirect Participant relating to or payments made on account of
beneficial ownership interests in the Global Note, or for maintaining,
supervising or reviewing any of the depository's records or records of
any Participant or Indirect Participant relating to the beneficial
ownership interests in the Global Note, or

. any other matter relating to the actions and practices of the depository
or any of its Participants or Indirect Participants.

The depository has advised us that its current practice, upon receipt of
any payment in respect of securities such as the exchange notes (including
principal and interest), is to credit the accounts of the relevant
Participants with the payment on the payment date, in amounts proportionate to
their respective holdings in principal amount of beneficial interests in the
relevant security as shown on the records of the depository, unless the
depository has reason to believe it will not receive payment on such payment
date. Payments by the Participants and the Indirect Participants to the
beneficial owners of exchange notes will be governed by standing instructions
and customary practices and will be the responsibility of the Participants or
the Indirect Participants and will not be the responsibility of the
depository, the Trustee or us, as the case may be.

Neither we nor the Trustee will be liable for any delay by the depository
or any of its Participants or Indirect Participants in identifying the
beneficial owners of the related exchange notes, and we and the Trustee may
conclusively rely on, and will be protected in relying on, instructions from
the Global Note Registered Owner for all purposes.

Transfers between Participants in DTC will be effected in accordance with
DTC's procedures and will be settled in same-day funds. Transfers between
participants in Euroclear and Cedelbank will be effected in the ordinary way
in accordance with their respective rules and operating procedures.
Transactions settled through DTC, Euroclear and Cedelbank will settle on a T +
5 basis.

We expect that DTC, Euroclear or Cedelbank, as applicable, will take any
action permitted to be taken by a holder of notes only at the direction of one
or more Participants to whose account the interest in a Global Note is
credited and only in respect of such portion of the aggregate principal amount
of notes as to which such Participant or Participants has or have given such
direction. However, if there is an Event of Default under the notes, DTC,
Euroclear or Cedelbank, as applicable, will exchange the applicable Global
Notes for Certificated Notes which it will distribute to its participants and
which may be legended.

Subject to compliance with the transfer restrictions applicable to the
Global Notes, cross-market transfers between the Participants in DTC, on the
one hand, and Euroclear or Cedelbank participants, on the other hand, will be
effected through DTC in accordance with DTC's rules on behalf of each of
Euroclear or Cedelbank by its common depositary. However, such cross-market
transactions will require delivery of instructions to Euroclear

96
<PAGE>

or Cedelbank by the counterparty in such system in accordance with the rules
and procedures and within the established deadlines (Brussels time) of such
system. Euroclear or Cedelbank will, if the transaction meets its settlement
requirements, deliver instructions to its common depositary to take action to
effect final settlement on its behalf by delivering or receiving interests in
the Global Notes in DTC, and making or receiving payments in accordance with
normal procedures for same-day funds settlement applicable to DTC. Euroclear
participants and Cedelbank participants may not deliver instructions directly
to the common depositaries for Euroclear or Cedelbank.

Because of time zone differences, the securities account of a Euroclear or
Cedelbank participant purchasing an interest in a Global Note from a
Participant in DTC will be credited, and any such crediting will be reported
to the relevant Euroclear or Cedelbank participant, during the securities
settlement processing day (which must be a business day for Euroclear and
Cedelbank) immediately following the settlement date of DTC. Cash received in
Euroclear or Cedelbank as a result of sales of interest in a Global Note by or
through a Euroclear or Cedelbank Participant to a Participant in DTC will be
received with value on the settlement date of DTC but will be available in the
relevant Euroclear or Cedelbank cash account only as of the business day for
Euroclear or Cedelbank following DTC's settlement date.

Although DTC, Euroclear and Cedelbank are expected to follow the foregoing
procedures in order to facilitate transfers of interests in a Global Note
among Participants of DTC, Euroclear and Cedel Bank, as the case may be, they
are under no obligation to perform or continue to perform such procedures, and
such procedures may be discontinued at any time. None of us, the Trustee or
any paying agent will have any responsibility for the performance by DTC,
Euroclear or Cedelbank or their respective participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.

If DTC is at any time unwilling or unable to continue as a depositary, or
Euroclear and Cedelbank cease to be a clearing agency, for the Global Notes
and a successor depositary or clearing agency is not appointed by us within 90
days, we will issue Certificated Notes which may bear a legend in exchange for
the Global Notes. Holders of an interest in a Global Note may receive
Certificated Notes which may bear such legend in accordance with DTC's rules
and procedures in addition to those provided for under the Indenture.

Quarter Period as if such Indebtedness was incurred, repaid or retired at

case since the first day of the Four Quarter Period, assuming such
acquisition or disposition had been consummated on the first day of the
Four Quarter Period and after giving pro forma effect to net cost savings
that the Company reasonably believes in good faith could have been achieved
during the Four Quarter Period as a result of such acquisition or
disposition (provided that both (A) such cost savings were identified and
quantified in an Officers' Certificate delivered to the Trustee at the time
of the consummation of the acquisition or disposition and (B) with respect
to each acquisition or disposition completed prior to the 90th day
preceding such date of determination, actions were commenced or initiated
by the Company within 90 days of such acquisition or disposition to effect
such cost savings identified in such Officers' Certificate and with respect
to any other acquisition or disposition, such Officers' Certificate sets
forth the specific steps to be taken within the 90 days after such
acquisition or disposition to accomplish such cost savings); and

(5) the occurrence of any of the events described in clauses (1)-(4)
above by any Person that has become a Restricted Subsidiary or has been
merged with or into the Company or any Restricted Subsidiary during such
Reference Period; and

provided further that (x) in making such computation, the Consolidated
Interest Expense attributable to interest on any Indebtedness computed on a
pro forma basis and (A) bearing a floating interest rate shall be computed as
if the rate in effect on the date of computation had been the applicable rate
for the entire period (taking into account any Interest Rate Agreements
applicable to such Indebtedness) and (B) which was not outstanding during the
period for which the computation is being made but which bears, at the option
of the Company, a fixed or floating rate of interest shall be computed by
applying, at the option of the Company, either the fixed or floating rate, and
(y) in making such computation, the Consolidated Interest Expense of the
Company attributable to interest on any Indebtedness under a revolving credit
facility computed on a pro forma basis shall be computed based upon the pro
forma average daily balance of such Indebtedness during the applicable period.

"Consolidated Net Worth" means, at any date of determination, stockholders'

Subsidiary (except as specified below) may Incur each and all of the
following:

(i) Indebtedness of the Company or its Restricted Subsidiaries
outstanding at any time in an aggregate principal amount not to exceed

Company, shall be unsubordinated) and any event which results in any such
Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
subsequent transfer of such Indebtedness (other than to the Company or
another Restricted Subsidiary) shall be deemed, in each case, to constitute
an Incurrence of such Indebtedness not permitted by this clause (iv);

be refinanced is subordinated to the Notes and

<PAGE>

(B) under Currency Agreements and Interest Rate Agreements; provided
that such agreements (a) are designed solely to protect the Company or
its Restricted Subsidiaries against fluctuations in foreign currency
exchange rates or interest rates and (b) do not increase the
Indebtedness of the obligor outstanding at any time (except to the
extent Incurred under another clause hereof) other than as a result of
fluctuations in foreign currency exchange rates or interest rates or by
reason of fees, indemnities and compensation payable thereunder, and

(C) arising from agreements providing for indemnification, adjustment
of purchase price or similar obligations, or from Guarantees or letters
of credit, surety bonds or performance bonds securing any obligations of
the Company or any of its Restricted Subsidiaries pursuant to such
agreements, in each case Incurred in connection with the disposition of
any business, assets or Restricted Subsidiary (other than Guarantees of

accordance with the "Limitation on Issuance of Guarantees by Restricted
Subsidiaries" covenant described below and any Guarantee by the Company of

outstanding, two times the sum of:

(A) the Net Cash Proceeds received by the Company after the Closing
Date from the issuance and sale of its Capital Stock (other than

to the extent such Net Cash Proceeds have not been used pursuant to
clause (iv)(C)(2) of paragraph 1 or clause (iii) or (iv) of paragraph 2
of the "Limitation on Restricted Payments" covenant described below or
clause (v) of the definition of "Permitted Investments" to make a
Restricted Payment, and

of Capital Stock has not been used pursuant to clause (iii) or (iv) of
paragraph 2 of the "Limitation on Restricted Payments" covenant

Indebtedness with respect to reimbursement type obligations regarding

Incurrence;

(xii) Indebtedness of Persons that are acquired by the Company or any of
its Restricted Subsidiaries or merged into a Restricted Subsidiary in
accordance with the terms of the Indenture; provided that such Indebtedness
is not incurred in contemplation of such acquisition or merger; and
provided further that after giving effect to such acquisition or merger,
either (x) the Company would be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Consolidated Leverage Ratio test
set forth in paragraph 1 of this covenant or (y) the Consolidated Leverage
Ratio is lower (if greater than zero) or higher (if less than zero) than
immediately prior to such acquisition; and

(xiii) Strategic Subordinated Indebtedness.

3. Notwithstanding any other provision of this "Limitation on Indebtedness"
covenant, the maximum amount of Indebtedness that the Company or a Restricted
Subsidiary may Incur pursuant to this "Limitation on Indebtedness" covenant
shall not be deemed to be exceeded with respect to any outstanding
Indebtedness due solely to the result of fluctuations in the exchange rates of
currencies. Accretion on an instrument issued at a discount will not be deemed
to constitute an Incurrence of Indebtedness.

4. For purposes of determining any particular amount of Indebtedness under
this "Limitation on Indebtedness" covenant, (1) Guarantees, Liens or
obligations with respect to letters of credit supporting Indebtedness
otherwise included in the determination of such particular amount shall not be
included and (2) any Liens granted pursuant to the equal and ratable

Indebtedness meets the criteria of more than one of the types of Indebtedness
described in the proviso in paragraph 1 above or in the clauses in paragraph 2
above, the Company, in its sole discretion, shall classify, and may from time
to time reclassify, such item of Indebtedness and only be required to include

clauses.

Subsidiary to an Unrestricted Subsidiary) accrued on a cumulative

supplement, refunding, replacement or refinancing.

3. Nothing contained in this "Limitation on Dividend and Other Payment
Restrictions Affecting Restricted Subsidiaries" covenant shall prevent the
Company or any Restricted Subsidiary from (1) creating, incurring, assuming or

issuance or sale would have been permitted to be made under the "Limitation
on Restricted Payments" covenant if made on the date of such issuance or
sale; or

(iv) issuances or sales of Common Stock (including options, warrants or
other rights to purchase shares of such Common Stock) of a Restricted
Subsidiary, provided that the Company or any Restricted Subsidiary applies
an amount equal to the Net Cash Proceeds thereof in accordance with the
"Limitation on Asset Sales" covenant.

Limitation on Issuances of Guarantees by Restricted Subsidiaries

1. The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company which is pari passu
with or subordinate in right of payment to the Notes ("Guaranteed
Indebtedness"), unless:

(i) such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture to the Indenture providing for a Guarantee (a
"Subsidiary Guarantee") of payment of the Notes by such Restricted
Subsidiary and

119
<PAGE>

(ii) such Restricted Subsidiary waives and will not in any manner
whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the
Company or any other Restricted Subsidiary as a result of any payment by
such Restricted Subsidiary under its Subsidiary Guarantee; provided that
this paragraph 1 shall not be applicable to any Guarantee of any Restricted
Subsidiary (x) that existed at the time such Person became a Restricted
Subsidiary and was not Incurred in connection with, or in contemplation of,
such Person becoming a Restricted Subsidiary or (y) of the Indebtedness
Incurred under the Senior Secured Credit Facility.

2. If the Guaranteed Indebtedness is (A) pari passu in right of payment
with the Notes, then the Guarantee of such Guaranteed Indebtedness shall be
pari passu in right of payment with, or subordinated to, the Subsidiary
Guarantee or (B) subordinated in right of payment to the Notes, then the
Guarantee of such Guaranteed Indebtedness shall be subordinated in right of
payment to the Subsidiary Guarantee at least to the extent that the Guaranteed
Indebtedness is subordinated to the Notes.

3. Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon:

(i) any sale, exchange or transfer, to any Person not an Affiliate of
the Company, of all of the Company's and each Restricted Subsidiary's
Capital Stock in, or all or substantially all the assets of, such
Restricted Subsidiary (which sale, exchange or transfer is not prohibited
by the Indenture) or

(ii) the release or discharge of the Guarantee which resulted in the
creation of such Subsidiary Guarantee, except a discharge or release by or
as a result of payment under such Guarantee.

Limitation on Transactions with Shareholders and Affiliates

1. The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction
(including, without limitation, the purchase, sale, lease or exchange of
property or assets, or the rendering of any service) with any Affiliate of the
Company or any Restricted Subsidiary, except upon fair and reasonable terms no
less favorable to the Company or such Restricted Subsidiary than could be
obtained, at the time of such transaction or, if such transaction is pursuant
to a written agreement, at the time of the execution of the agreement
providing therefor, in a comparable arm's-length transaction with a Person
that is not such a holder or an Affiliate.

2. The foregoing limitation does not limit, and shall not apply to

(i) transactions:

(A) approved by a majority of the disinterested members of the Board
of Directors, or

(B) for which the Company or a Restricted Subsidiary delivers to the
Trustee a written opinion of a nationally recognized investment banking
firm or a nationally recognized firm having expertise in the specific
area which is the subject of such determination stating that the
transaction is fair to the Company or such Restricted Subsidiary from a
financial point of view;

(ii) any transaction solely between the Company and any of its
Restricted Subsidiaries or solely between Restricted Subsidiaries;

(iii) the payment of reasonable and customary regular fees to, and
indemnity provided on behalf of, officers, directors, employees or
consultants of the Company or its Restricted Subsidiaries;

(iv) any payments or other transactions pursuant to any tax-sharing
agreement between the Company and any other Person with which the Company
files a consolidated tax return or with which the Company is part of a
consolidated group for tax purposes;

(v) any agreement as in effect as of the Closing Date or any amendment
thereto (so long as any such amendment is not disadvantageous to the
Holders in any material respect);

120
<PAGE>

(vi) the existence of, or the performance by the Company or any of its
Restricted Subsidiaries of its obligations under the terms of, any
stockholders agreement (including any registration rights agreement or
purchase agreement related thereto) to which it is a party as of the
Closing Date and any similar agreements which it may enter into thereafter
(so long as any such amendment is not disadvantageous to the Holders in any
material respect);

(vii) any Permitted Investments and Restricted Payments not prohibited
by the "Limitation on Restricted Payments" covenant; or

(viii) the issuance of any Capital Stock (other than Disqualified Stock)
of the Company.

Notwithstanding the foregoing, any transaction or series of related
transactions covered by paragraph 1 of this "Limitation on Transactions with
Shareholders and Affiliates" covenant and not covered by clauses (ii) through
(vii) of this paragraph 2 the aggregate amount of which exceeds $3.0 million
in value, must be approved or determined to be fair in the manner provided for
in clause (i)(A) or (B) above.

Limitation on Liens

1. The Company will not, and will not permit any Restricted Subsidiary to,
create, incur, assume or suffer to exist any Lien on any of its assets or
properties of any character (including, without limitation, licenses), or any
shares of Capital Stock or Indebtedness of any Restricted Subsidiary, without
making effective provision for all of the Notes and all other amounts due
under the Indenture to be directly secured equally and ratably with (or, if
the obligation or liability to be secured by such Lien is subordinated in
right of payment to the Notes, prior to) the obligation or liability secured
by such Lien.

2. The foregoing limitation does not apply to:

(i) Liens existing on the Closing Date or required on the Closing Date
to be provided in the future;

(ii) Liens securing obligations under the Senior Secured Credit Facility
(including Liens pursuant to after-acquired clauses);

(iii) Liens granted after the Closing Date on any assets or Capital
Stock of the Company or its Restricted Subsidiaries created in favor of the
Holders;

(iv) Liens with respect to the assets of a Restricted Subsidiary granted
by such Restricted Subsidiary to the Company or a Restricted Subsidiary to
secure Indebtedness owing to the Company or such other Restricted
Subsidiary;

(v) Liens securing Indebtedness which is Incurred to refinance secured
Indebtedness which is permitted to be Incurred under clause (v) of
paragraph 2 of the "Limitation on Indebtedness" covenant; provided that
such Liens do not extend to or cover any property or assets of the Company
or any Restricted Subsidiary other than the property or assets securing the
Indebtedness being refinanced;

(vi) Liens on any property or assets of a Restricted Subsidiary securing
Indebtedness of such Restricted Subsidiary permitted under the "Limitation
on Indebtedness" covenant; or

(vii) Permitted Liens.

Limitation on Sale-Leaseback Transactions

1. The Company will not, and will not permit any Restricted Subsidiary to,
enter into any sale-leaseback transaction involving any of its assets or
properties whether now owned or hereafter acquired, whereby the Company or a
Restricted Subsidiary sells or transfers such assets or properties and then or
thereafter leases such assets or properties or any part thereof or any other
assets or properties which the Company or such Restricted Subsidiary, as the
case may be, intends to use for substantially the same purpose or purposes as
the assets or properties sold or transferred.

121
<PAGE>

2. The foregoing restriction does not apply to any sale-leaseback
transaction if:

(i) the lease is for a period, including renewal rights, of not in
excess of three years;

(ii) the lease secures or relates to industrial revenue or pollution
control bonds;

(iii) the transaction is solely between the Company and any Wholly Owned
Restricted Subsidiary or solely between Wholly Owned Restricted
Subsidiaries; or

(iv) the Company or such Restricted Subsidiary, within 12 months after
the sale or transfer of any assets or properties is completed, applies an
amount not less than the net proceeds received from such sale in accordance
with clause (A) or (B) of paragraph 2 of the "Limitation on Asset Sales"
covenant described below.

Limitation on Asset Sales

1. The Company will not, and will not permit any Restricted Subsidiary to,
consummate any Asset Sale, unless:

(i) the consideration received by the Company or such Restricted
Subsidiary is at least equal to the fair market value of the assets sold or
disposed of and

(ii) at least 75% of the consideration received consists of cash or
Temporary Cash Investments.

For purposes of this covenant, the following are deemed to be cash:

(x) the principal amount or accreted value (whichever is larger) of
Indebtedness of the Company or any Restricted Subsidiary with respect to
which the Company or such Restricted Subsidiary has either (A) received a
written release or (B) been released by operation of law, in either case,
from all liability on such Indebtedness in connection with such Asset Sale
and

(y) securities received by the Company or any Restricted Subsidiary from
the transferee that are promptly converted by the Company or such
Restricted Subsidiary into cash.

2. In the event and to the extent that the Net Cash Proceeds received by
the Company or any of its Restricted Subsidiaries from one or more Asset Sales
occurring on or after the Closing Date in any period of 12 consecutive months
exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as of the
date closest to the commencement of such 12-month period for which a
consolidated balance sheet of the Company and its Subsidiaries has been filed
with the Commission or provided to the Trustee pursuant to the "Commission
Reports and Reports to Holders" covenant), then the Company shall or shall
cause the relevant Restricted Subsidiary to:

(i) within 12 months after the date Net Cash Proceeds so received exceed
10% of Adjusted Consolidated Net Tangible Assets:

(A) apply an amount equal to such excess Net Cash Proceeds to
permanently repay unsubordinated Indebtedness of the Company or any
Restricted Subsidiary providing a Subsidiary Guarantee pursuant to the
"Limitation on Issuances of Guarantees by Restricted Subsidiaries"
covenant described above or Indebtedness of any other Restricted
Subsidiary, in each case owing to a Person other than the Company or
any of its Restricted Subsidiaries or

(B) invest an equal amount, or the amount not so applied pursuant to
clause (A) (or enter into a definitive agreement committing to so
invest within 12 months after the date of such agreement), in property
or assets (other than current assets) of a nature or type or that are
used in a business (or in a Person (other than a natural person) having
property and assets of a nature or type, or engaged in a business)
similar or related to the nature or type of the property and assets of,
or the business of, the Company and its Restricted Subsidiaries
existing on the date of such investment (as determined in good faith by
the Board of Directors, whose determination shall be conclusive and
evidenced by a Board Resolution) and

122
<PAGE>

(ii) apply (no later than the end of the 12-month period referred to in
clause (i)) such excess Net Cash Proceeds (to the extent not applied
pursuant to clause (i)) as provided in the following paragraph 3 of this
"Limitation on Asset Sales" covenant.

The amount of such excess Net Cash Proceeds required to be applied (or to
be committed to be applied) during such 12-month period as set forth in clause
(i) of the preceding sentence and not applied as so required by the end of
such period shall constitute "Excess Proceeds."

3. If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to
this "Limitation on Asset Sales" covenant totals at least $5 million, the
Company must commence, not later than the fifteenth Business Day of such
month, and consummate an Offer to Purchase from the Holders on a pro rata
basis, and an offer to purchase any outstanding Indebtedness with similar
provisions requiring the Company to make an offer to purchase such
Indebtedness, in an aggregate principal amount of the Notes and such pari
passu Indebtedness equal to:

(A) with respect to the Notes, the product of such Excess Proceeds
multiplied by a fraction, the numerator of which is the outstanding
principal amount of the Notes and the denominator of which is the sum of
the outstanding principal amount of the Notes and such pari passu
Indebtedness (the product hereinafter referred to as the "Note Amount"),
and

(B) with respect to the pari passu Indebtedness, the excess of the
Excess Proceeds over the Note Amount,

at a purchase price equal to 100% of the principal amount or accreted value of
such pari passu Indebtedness, as the case may be, on the relevant Payment Date
or such other date set forth in the documentation governing the pari passu
Indebtedness, plus, in each case, accrued interest (if any) to the Payment
Date or such other date set forth in the documentation governing the pari
passu Indebtedness. If the aggregate purchase price of the Notes tendered
pursuant to the Offer to Purchase is less than the Excess Proceeds, the
remaining will be available for use by the Company for general corporate
purposes. Upon the consummation of any Offer to Purchase in accordance with
the terms of the Indenture, the amount of Net Cash Proceeds from Asset Sales
subject to any future Offer to Purchase shall be deemed to be zero.

Repurchase of Notes Upon a Change of Control

The Company must commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Notes then outstanding,
at a purchase price equal to 101% of the principal amount of the Notes on the
relevant Payment Date, plus accrued interest (if any) to the Payment Date;
provided, however, that notwithstanding the occurrence of a Change of Control,
the Company shall not be obligated to purchase the Notes pursuant to this
covenant in the event that it has irrevocably committed to, within 90 days of
such Change of Control, redeem all the Notes in accordance with the terms
hereof.

There can be no assurance that the Company will have sufficient funds
available at the time of any Change of Control to make any debt payment
(including repurchases of Notes) required by the foregoing covenant (as well
as may be contained in other securities of the Company which might be
outstanding at the time). The above covenant requiring the Company to
repurchase the Notes will, unless consents are obtained, require the Company
to repay all indebtedness then outstanding which by its terms would prohibit
such Note repurchase, either prior to or concurrently with such Note
repurchase.

Commission Reports and Reports to Holders

At all times from and after the earlier of (i) the date of the commencement
of an exchange offer or the effectiveness of a Shelf Registration Statement
(the "Registration") and (ii) the date that is six months after the Closing
Date, in either case, whether or not the Company is then required to file
reports with the Commission, the Company shall deliver for filing with the
Commission all such reports and other information as it would be

123
<PAGE>

required to file with the Commission by Section 13(a) or 15(d) under the
Exchange Act if it were subject thereto. All references herein to reports
"filed" with the Commission shall be deemed to refer to the reports then most
recently delivered for filing, whether or not accepted by the Commission. The
Company shall supply the Trustee and each Holder or shall supply to the
Trustee for forwarding to each such Holder, without cost to such Holder,
copies of such reports and other information. In addition, at all times prior
to the earlier of the date of the Registration and the date that is six months
after the Closing Date, the Company shall, at its cost, deliver to each Holder
of the Notes quarterly and annual reports substantially equivalent to those
which would be required by the Exchange Act (or, in lieu thereof, the
Registration Statement on Form S-1, S-3 or S-4 filed or to be filed with the
Commission in connection with the exchange offer or the Shelf Registration
Statement, if such form and any amendments thereof contains comparable
information). In addition, at all times prior to the Registration, upon the
request of any Holder or any prospective purchaser of the Notes designated by
a Holder, the Company shall supply to such Holder or such prospective
purchaser the information required under Rule 144A under the Securities Act.

Events of Default

1. The following events are defined as "Events of Default" in the
Indenture:

(a) default in the payment of principal of (or premium, if any, on) any
Note when the same becomes due and payable at maturity, upon acceleration,
redemption or otherwise;

(b) default in the payment of interest on any Note when the same becomes
due and payable, and such default continues for a period of 30 days;

(c) the Company or the Guarantor defaults in the performance of or
breaches any other covenant or agreement of the Company or the Guarantor in
the Indenture or under the Notes (other than a default specified in clause
(a) or (b) above) and such default or breach continues for a period of 30
consecutive days after written notice by the Trustee or the Holders of 25%
or more in aggregate principal amount of the Notes;

(d) the Company shall have failed to make or consummate an Offer to
Purchase in accordance with the "Limitation on Asset Sales" covenant above;

(e) the Company shall have failed to make or consummate an Offer to
Purchase in accordance with the provisions of "Repurchase of Notes Upon a
Change of Control" above;

(f) there occurs with respect to any issue or issues of Indebtedness of
the Company or any Significant Subsidiary having an outstanding principal
amount at maturity of $5 million or more in the aggregate for all such
issues of all such Persons, whether such Indebtedness now exists or shall
hereafter be created,

(I) an event of default that has caused the holder thereof to
declare such Indebtedness to be due and payable prior to its Stated
Maturity and such Indebtedness has not been discharged in full or such
acceleration has not been rescinded or annulled within 30 days of such
acceleration and/or
(II) the failure to make a principal payment at the final (but not
any interim) fixed maturity and such defaulted payment shall not have
been made, waived or extended within 30 days of such payment default;

(g) any final judgment or order (not covered by insurance) for the
payment of money in excess of $5 million in the aggregate (treating any
deductibles, self-insurance or retention as not so covered) shall be
rendered against the Company or any Significant Subsidiary and shall not be
paid or discharged, and there shall be any period of 30 consecutive days
following entry of the final judgment or order that causes the aggregate
amount for all such final judgments or orders outstanding and not paid or
discharged against the Company or any of its Significant Subsidiaries to
exceed $5 million during which a stay of enforcement of such final judgment
or order, by reason of a pending appeal or otherwise, shall not be in
effect;

124
<PAGE>

(h) a court having jurisdiction in the premises enters a decree or order
for:

(A) relief in respect of the Company, the Guarantor or any
Significant Subsidiary in an involuntary case under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect,

(B) appointment of a receiver, liquidator, assignee, custodian,
trustee, sequestrator or similar official of the Company, the Guarantor
or any Significant Subsidiary or for all or substantially all of the
property and assets of the Company, the Guarantor or any Significant
Subsidiary or

(C) the winding up or liquidation of the affairs of the Company, the
Guarantor or any Significant Subsidiary and, in each case, such decree
or order shall remain unstayed and in effect for a period of 30
consecutive days;

(i) the Company, the Guarantor or any Significant Subsidiary:

(A) commences a voluntary case under any applicable bankruptcy,
insolvency or other similar law now or hereafter in effect, or consents
to the entry of an order for relief in an involuntary case under any
such law,

(B) consents to the appointment of or taking possession by a
receiver, liquidator, assignee, custodian, trustee, sequestrator or
similar official of the Company, the Guarantor or any Significant
Subsidiary or for all or substantially all of the property and assets
of the Company, the Guarantor or any Significant Subsidiary or

(j) prior to the payment in full of the first six interest payments on
the Notes, the Note Guarantee ceases to be in full force and effect or is
declared null and void, or the Guarantor denies that it has any further
liability under the Note Guarantee, or gives notice to such effect (other
than by reason of the termination of the Indenture).

2. If an Event of Default (other than an Event of Default specified in
clause (h) or (i) above that occurs with respect to the Company or the
Guarantor) occurs and is continuing under the Indenture, the Trustee or the
Holders of at least 25% in aggregate principal amount of the Notes then
outstanding, by written notice to the Company (and to the Trustee if such
notice is given by the Holders), may, and the Trustee at the request of such
Holders shall, declare the principal of, premium, if any, and accrued interest
on the Notes to be immediately due and payable. Upon a declaration of
acceleration, such principal of, premium, if any, and accrued interest shall
be immediately due and payable. In the event of a declaration of acceleration
because an Event of Default set forth in clause (f) above has occurred and is
continuing, such declaration of acceleration shall be automatically rescinded
and annulled if the event of default triggering such Event of Default pursuant
to clause (f) shall be remedied or cured by the Company or the relevant
Significant Subsidiary or waived by the holders of the relevant Indebtedness
within 60 days after the declaration of acceleration with respect thereto. If
an Event of Default specified in clause (h) or (i) above occurs with respect
to the Company or the Guarantor, the principal of, premium, if any, and
accrued interest on the Notes then outstanding shall ipso facto become and be
immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder. The Holders of at least a majority in principal
amount of the outstanding Notes by written notice to the Company and to the
Trustee, may waive all past defaults and rescind and annul a declaration of
acceleration and its consequences if:

(i) all existing Events of Default, other than the nonpayment of the
principal of, premium, if any, and interest on the Notes that have become
due solely by such declaration of acceleration, have been cured or waived
and

(ii) the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction. For information as to the waiver of
defaults, see "--Modification and Waiver."

3. The Holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any

125
<PAGE>

trust or power conferred on the Trustee. However, the Trustee may refuse to
follow any direction that conflicts with law or the Indenture, that may
involve the Trustee in personal liability, or that the Trustee determines in
good faith may be unduly prejudicial to the rights of Holders of Notes not
joining in the giving of such direction and may take any other action it deems
proper that is not inconsistent with any such direction received from Holders
of Notes. A Holder may not pursue any remedy with respect to the Indenture or
the Notes unless:

(i) the Holder gives the Trustee written notice of a continuing Event of
Default;

(ii) the Holders of at least 25% in aggregate principal amount of
outstanding Notes make a written request to the Trustee to pursue the
remedy;

(iii) such Holder or Holders offer the Trustee indemnity satisfactory to
the Trustee against any costs, liability or expense;

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

(v) during such 60-day period, the Holders of a majority in aggregate
principal amount of the outstanding Notes do not give the Trustee a
direction that is inconsistent with the request.

However, such limitations do not apply to the right of any Holder of a Note
to receive payment of the principal of, premium, if any, or interest on, such
Note or to bring suit for the enforcement of any such payment, on or after the
due date expressed in the Notes, which right shall not be impaired or affected
without the consent of the Holder.

4. The Indenture will require certain officers of the Company to certify,
on or before a date not more than 90 days after the end of each fiscal year,
that a review has been conducted of the activities of the Company and its
Restricted Subsidiaries and the Company's and its Restricted Subsidiaries'
performance under the Indenture and that the Company has fulfilled all
obligations thereunder, or, if there has been a default in the fulfillment of
any such obligation, specifying each such default and the nature and status
thereof. The Company will also be obligated to notify the Trustee of any
default or defaults in the performance of any covenants or agreements under
the Indenture.

Consolidation, Merger and Sale of Assets

The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its
property and assets (as an entirety or substantially an entirety in one
transaction or a series of related transactions) to, any Person or permit any
Person to merge with or into the Company unless:

(i) the Company shall be the continuing Person, or the Person (if other
than the Company) formed by such consolidation or into which the Company is
merged or that acquired or leased such property and assets of the Company
shall be a corporation organized and validly existing under the laws of the
United States of America or any jurisdiction thereof and shall expressly
assume, by a supplemental indenture, executed and delivered to the Trustee,
all of the obligations of the Company on all of the Notes and under the
Indenture;

(ii) immediately after giving effect to such transaction, no Default or
Event of Default shall have occurred and be continuing;

(iii) immediately after giving effect to such transaction on a pro forma
basis,

(A) the Company or any Person becoming the successor obligor of the
Notes, as the case may be, shall have a Consolidated Net Worth equal to
or greater than the Consolidated Net Worth of the Company immediately
prior to such transaction or

(B) the Company or any Person becoming the successor obligor of the
Notes, as the case may be, shall have a Consolidated Leverage Ratio no
more than the greater of (I) 6:1 and (II) the Consolidated Leverage
Ratio of the Company immediately prior to such transaction;

126
<PAGE>

provided that this clause (iii) shall not apply to a consolidation or
merger with or into a Wholly Owned Restricted Subsidiary with a positive
net worth; provided that, in connection with any such merger or
consolidation, no consideration (other than Capital Stock (other than
Disqualified Stock) in the surviving Person or the Company) shall be issued
or distributed to the stockholders of the Company; and

(iv) the Company delivers to the Trustee an Officers' Certificate
(attaching the arithmetic computations to demonstrate compliance with
clause (iii) above) and an Opinion of Counsel, in each case stating that
such consolidation, merger or transfer and such supplemental indenture
complies with this provision and that all conditions precedent provided for
herein relating to such transaction have been complied with;

provided, however, that clause (iii) above does not apply if, in the good
faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board Resolution, the principal purpose
of such transaction is part of a plan to change the state of incorporation of
the Company; and that any such transaction shall not have as one of its
purposes the evasion of the foregoing limitations.

Defeasance

1. Defeasance and Discharge. The Indenture provides that the Company will
be deemed to have paid and will be discharged from any and all obligations in
respect of the Notes on the 123rd day after the deposit referred to below, and
the provisions of the Indenture will no longer be in effect with respect to
the Notes (except for, among other matters, certain obligations to register
the transfer or exchange of the Notes, to replace stolen, lost or mutilated
Notes, to maintain paying agencies and to hold monies for payment in trust)
if, among other things,

(A) the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and
principal in respect thereof in accordance with their terms will provide
money in an amount sufficient to pay the principal of, premium, if any, and
accrued interest on the Notes on the Stated Maturity of such payments in
accordance with the terms of the Indenture and the Notes,

(B) the Company has delivered to the Trustee:

(i) either:

(x) an Opinion of Counsel to the effect that Holders will not
recognize income, gain or loss for federal income tax purposes as a
result of the Company's exercise of its option under this
"Defeasance" provision and will be subject to federal income tax on
the same amount and in the same manner and at the same times as
would have been the case if such deposit, defeasance and discharge
had not occurred, which Opinion of Counsel must be based upon (and
accompanied by a copy of) a ruling of the Internal Revenue Service
to the same effect unless there has been a change in applicable
federal income tax law after the Closing Date such that a ruling is
no longer required or

(y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of
Counsel, and

(ii) an Opinion of Counsel to the effect that the creation of the
defeasance trust does not violate the Investment Company Act of 1940
and after the passage of 123 days following the deposit, the trust fund
will not be subject to the effect of Section 547 of the United States
Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law,

(C) immediately after giving effect to such deposit on a pro forma
basis, no Event of Default, or event that after the giving of notice or
lapse of time or both would become an Event of Default, shall have occurred
and be continuing on the date of such deposit or during the period ending
on the 123rd day after the date of such deposit, and such deposit shall not
result in a breach or violation of, or constitute a default under, any
other agreement or instrument to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries
is bound and

127
<PAGE>

(D) if at such time the Notes are listed on a national securities
exchange, the Company has delivered to the Trustee an Opinion of Counsel to
the effect that the Notes will not be delisted as a result of such deposit,
defeasance and discharge, provided that if simultaneously with the deposit
of the money and/or U.S. Government Obligations referred to in (A) above,
the Company has caused an irrevocable, transferable, standby letter of
credit to be issued by a bank with capital and surplus exceeding the
principal amount of the Notes then outstanding, expiring not earlier than
180 days from its issuance, in favor of the Trustee which permits the
Trustee to draw an amount equal to the principal, premium, if any, and
accrued interest on the Notes through the expiry date of the letter of
credit, then the Company will be deemed to have paid and discharged any and
all obligations in respect of the Notes on the date of the deposit and
issuance of the letter of credit.

2. Defeasance of Certain Covenants and Certain Events of Default. The
Indenture further provides that the provisions of the Indenture will no longer
be in effect with respect to clause (iii) under "Consolidation, Merger and
Sale of Assets" and all the covenants described herein under "Covenants,"
clause (c) under "Events of Default" with respect to such other covenants and
clauses (c), (d), (e), (f) and (g) under "Events of Default" shall be deemed
not to be Events of Default upon, among other things, the deposit with the
Trustee, in trust, of money and/or U.S. Government Obligations that through
the payment of interest and principal in respect thereof in accordance with
their terms will provide money in an amount sufficient to pay the principal
of, premium, if any, and accrued interest on the Notes on the Stated Maturity
of such payments in accordance with the terms of the Indenture and the Notes,
the satisfaction of the provisions described in clauses (B)(ii), (C) and (D)
of the preceding paragraph 1 and the delivery by the Company to the Trustee of
an Opinion of Counsel to the effect that, among other things, the Holders will
not recognize income, gain or loss for federal income tax purposes as a result
of such deposit and defeasance of certain covenants and Events of Default and
will be subject to federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit and
defeasance had not occurred.

3. Defeasance and Certain Other Events of Default. In the event the Company
exercises its option to omit compliance with certain covenants and provisions
of the Indenture with respect to the Notes as described in the immediately
preceding paragraph 2 and the Notes are declared due and payable because of
the occurrence of an Event of Default that remains applicable, the amount of
money and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Notes at the time of their Stated
Maturity but may not be sufficient to pay amounts due on the Notes at the time
of the acceleration resulting from such Event of Default. However, the Company
will remain liable for such payments.

Modification and Waiver

Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the Holders of not less than a majority in
aggregate principal amount of the outstanding Notes; provided, however, that
no such modification or amendment may, without the consent of each Holder
affected thereby,

(i) change the Stated Maturity of the principal of, or any installment
of interest on, any Note,

(ii) reduce the principal amount of, or premium, if any, or interest on,
any Note,

(iii) change the place or currency of payment of principal of, or
premium, if any, or interest on, any Note,

(iv) impair the right to institute suit for the enforcement of any
payment on or after the Stated Maturity (or, in the case of a redemption,
on or after the Redemption Date) of any Note,

(v) reduce the above-stated percentage of outstanding Notes the consent
of whose Holders is necessary to modify or amend the Indenture,

(vi) waive a default in the payment of principal of, premium, if any, or
interest on the Notes or

128
<PAGE>

(vii) reduce the percentage or aggregate principal amount of outstanding
Notes the consent of whose Holders is necessary for waiver of compliance
with certain provisions of the Indenture or for waiver of certain defaults.

Guarantee

The Company's obligations under the Notes are fully and unconditionally
guaranteed on an unsubordinated basis (the "Note Guarantee") by KMC Telecom
Financing, Inc., a Wholly-Owned Restricted Subsidiary of the Company that has
no assets, other than certain rights relating to the Pledged Securities;
provided that the Note Guarantee shall not be enforceable against KMC Telecom
Financing, Inc. in an amount in excess of the net worth of KMC Telecom
Financing, Inc. at the time that determination of such net worth is, under
applicable law, relevant to the enforceability of the Note Guarantee. Such net
worth shall include any claim of KMC Telecom Financing, Inc. against the
Company for reimbursement. After the first six interest payments on the Notes
are paid in full, the Note Guarantee will terminate and the Guarantor will
have no further obligations in respect of the Indenture or the Notes.

No Personal Liability of Incorporators, Stockholders, Officers, Directors, or
Employees

The Indenture provides that no recourse for the payment of the principal
of, premium, if any, or interest on any of the Notes or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture, or in any
of the Notes or because of the creation of any Indebtedness represented
thereby, shall be had against any incorporator, stockholder, officer,
director, employee or controlling person of the Company or of any successor
Person thereof. Each Holder, by accepting the Notes, waives and releases all
such liability.

Concerning the Trustee

The Indenture provides that, except during the continuance of a Default,
the Trustee will not be liable, except for the performance of such duties as
are specifically set forth in such Indenture. If an Event of Default has
occurred and is continuing, the Trustee will use the same degree of care and
skill in its exercise of the rights and powers invested in it under the
Indenture as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.

The Indenture and provisions of the Trust Indenture Act of 1939, as
amended, incorporated by reference therein contain limitations on the rights
of the Trustee, should it become a creditor of the Company, to obtain payment
of claims in certain cases or to realize on certain property received by it in
respect of any such claims, as security or otherwise. The Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest, it must eliminate such conflict or resign.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following summary sets forth the opinion of Kelley Drye & Warren LLP,
counsel to the Company, as to the principal U.S. federal income tax
consequences of an exchange of the original notes for the exchange notes and
the ownership and disposition of the exchange notes under U.S. federal income
tax laws as of the date hereof. This summary is based on current provisions of
the U.S. Internal Revenue Code of 1986, as amended (the "Code"), applicable
Treasury Regulations, judicial authority, and current administrative rulings
and pronouncements of the Internal Revenue Service, all of which are subject
to change, possibly with retroactive effect. There can be no assurance that
the Internal Revenue Service will not take a contrary view, and no ruling from
the Internal Revenue Service has been or will be sought by the Company.

This summary does not purport to deal with all aspects of taxation that may
be relevant to particular holders of the exchange notes in light of their
personal investment or tax circumstances, or to certain types of investors
(including individual retirement accounts and other tax deferred accounts,
insurance companies, financial institutions, broker-dealers, tax-exempt
organizations, holders holding the exchange notes as part of a hedge, straddle
or conversion transaction or holders whose functional currency is not the U.S.
dollar) subject to special treatment under the U.S. federal income tax laws.
In addition, except as otherwise provided, this discussion deals only with
exchange notes acquired by investors at their initial issue prices in the
offering of the notes, and held as capital assets within the meaning of
Section 1221 of the Code.

For purposes of this discussion, the term "U.S. Holder" means a citizen or
resident of the U.S., a corporation, limited liability company or partnership
created or organized in the U.S. or under the laws of the U.S. or any
political subdivision thereof, an estate the income of which is includible in
gross income for U.S. federal income tax purposes regardless of its source, or
a trust if a court within the U.S. is able to exercise primary supervision
over the administration of the trust and one or more U.S. persons has the
authority to control all substantial decisions of the trust. The term "Non-
U.S. Holder" means any person other than a U.S. Holder.

THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION ONLY. THE TAX TREATMENT
MAY VARY DEPENDING UPON A HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD
CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM
OF PURCHASING, HOLDING AND DISPOSING OF THE NOTES, INCLUDING THE APPLICABILITY
AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.

The Exchange

The exchange of original notes for exchange notes pursuant to the exchange
offer will not be a taxable event for U.S. federal income tax purposes. As a
result, there will not be any material U.S. federal income tax consequences to
a holder exchanging original notes for exchange notes pursuant to the exchange
offer.

Because each exchange note is a continuation of the corresponding original
note, the remainder of this discussion of certain federal income tax
consideration generally refers only to "notes."

The Notes

The Company intends to treat the notes as indebtedness for U.S. federal
income tax purposes. However, it is possible that the Service will contend
that the notes should be treated as an equity interest in, rather than as debt
of, the Company. If the notes are treated as equity, the amount of any actual
or constructive payments on a note would first be taxable to the holder as
dividend income to the extent of the Company's current and accumulated
earnings and profits, and then would be treated as a return of capital to the
extent of the holder's tax basis in the note, with any remaining amount
treated as gain from the sale of a note. As a result, until such time as the
Company has earnings and profits as determined for U.S. federal income tax
purposes, payments on a note treated as equity will be a nontaxable return of
capital and will be applied against and reduce the adjusted tax basis of such
note in the hands of its holder (but not below zero) and any excess will be
treated as gain from

130
<PAGE>

the sale of the note. Further, any payments on the notes treated as equity to
Non-U.S. Holders would not be eligible for the portfolio interest exception
from U.S. withholding tax, and dividends thereon would be subject to U.S.
withholding tax at a flat rate of 30% (or lower applicable treaty rate) and
gain from their sale or other taxable disposition might also be subject to
U.S. tax in certain circumstances. In addition, in the event of equity
treatment, the Company would not be entitled to deduct interest on the notes
for U.S. federal income tax purposes. The remainder of this discussion assumes
that the notes will constitute debt of the Company for such tax purposes.

Payments of Interest on the Notes

Interest paid on a note generally will be taxable to a U.S. Holder as
ordinary interest income at the time it accrues or is received, in accordance
with the U.S. Holder's regular method of accounting for federal income tax
purposes.

Mandatory and Optional Redemptions

In the event of a change of control, the Company will be required to offer
to redeem all of the notes at redemption prices specified elsewhere herein. In
the event that the Company receives net proceeds from certain sales of its
capital stock, the Company may, at any time prior to May 15, 2002, use all or
a portion of such net proceeds to redeem the notes in amounts and at
redemption prices specified elsewhere herein. Under Treasury Regulations
issued under provisions of the Code relating to original issue discount (the
"OID Regulations"), computation of yield and maturity of the notes is not
affected by such redemption rights and obligations if, based on all the facts
and circumstances as of the issue date, payments on the notes are
significantly more likely than not to occur in accordance with the stated
payment schedule of the notes (which does not reflect a change of control or
sales of certain kinds of the Company's capital stock). The Company believes,
based on all of the facts and circumstances as of the issue date, it is
significantly more likely than not that the notes will be paid according to
their stated schedule. Therefore, the Company will not take the redemption
rights and obligations into account in determining the yield and maturity of
the notes.

The Company may redeem the notes, in whole or in part, at any time on or
after May 15, 2004, at redemption prices specified elsewhere herein, plus
accrued and unpaid interest to the date of redemption. The OID Regulations
contain rules for determining yield and maturity of any instrument that may be
redeemed prior to its stated maturity date at the option of the issuer. Under
the OID Regulations, solely for purposes of the accrual of OID, it is assumed
that the issuer will exercise any option to redeem a debt instrument if such
exercise will lower the yield-to-maturity of the debt instrument. The Company
believes that it will not be presumed to redeem the notes prior to their
stated maturity under the foregoing rules because the exercise of such option
would not lower the yield-to-maturity of the notes.

Market Discount

If a U.S. Holder acquires a note for an amount that is less than its stated
redemption price at maturity, the amount of the difference will be treated as
"market discount," unless such difference is less than a specified de minimis
amount. Under the market discount rules of the Code, a U.S. Holder will be
required to treat any principal payment on, or any gain on the sale, exchange,
retirement or other disposition (including a gift) of, a note as ordinary
income to the extent of any accrued market discount that has not previously
been included in income. Market discount generally accrues on a straight-line
basis over the remaining term of the note, unless the U.S. Holder elects to
accrue market discount on a constant yield method based on compounding
interest. A U.S. Holder may not be allowed to deduct immediately all or a
portion of the interest expense on any indebtedness incurred or continued to
purchase or to carry such note.

A U.S. Holder may elect to include market discount in income currently as
it accrues (either on a straight-line basis or, if the U.S. Holder so elects,
on a constant-yield basis), in which case the interest deferral rule set forth
in the preceding paragraph will not apply. Such an election will apply to all
market discount bonds acquired

131
<PAGE>

by the U.S. Holder on or after the first day of the first taxable year to
which such election applies and may be revoked only with the consent of the
Internal Revenue Service.

Amortization of Bond Premium

A U.S. Holder that purchases a note for an amount in excess of the sum of
all remaining payments due on the note after the purchase date (other than
payments of qualified stated interest) will be considered to have purchased
the note at a premium. Such holder may elect to amortize such premium (as an
offset to interest income), using a constant-yield method, over the remaining
term of the note, subject to special rules for early redemption provisions.
Such election, once made, generally applies to all debt instruments held or
subsequently acquired by the U.S. Holder on or after the first day of the
first taxable year to which such election applies and may be revoked only with
the consent of the Internal Revenue Service. A U.S. Holder that elects to
amortize such premium must reduce its tax basis in the note by the amount of
the premium amortized during its holding period. If a U.S. Holder does not
elect to amortize bond premium, the amount of such premium will be included in
the U.S. Holder's tax basis for purposes of computing gain or loss in
connection with a taxable disposition of the note.

Sale or Other Disposition

In general, upon the sale, exchange or redemption of a note, a U.S. Holder
will recognize taxable gain or loss equal to the difference between (i) the
amount of cash and the fair market value of any property received on the sale,
exchange or redemption (not including any amount attributable to accrued but
unpaid interest) and (ii) the U.S. Holder's adjusted tax basis in the note. A
U.S. Holder's adjusted tax basis in a note generally will be equal to the cost
of the note to such U.S. Holder, increased by the amount of any market
discount previously included in income by the U.S. Holder and reduced by the
amount of any payment received by the U.S. Holder, other than payments of
qualified stated interest, and by the amount of amortizable bond premium taken
into account.

Subject to the discussion of market discount above, gain or loss realized
on the sale, exchange or redemption of a note will be capital gain or loss.
Capital gain recognized by certain non-corporate U.S. Holders, including
individuals, generally will be subject to a maximum federal income tax rate of
20% if the U.S. Holder held the note for more than one year. The deductibility
of capital losses is subject to limitations.

Non-U.S. Holders

In general, payments of interest on the notes by the Company or any paying
agent to a beneficial owner of a note that is a Non-U.S. Holder will not be
subject to U.S. withholding tax, provided that (i) such Non-U.S. Holder does
not own, actually or constructively, 10% or more of the total combined voting
power of all classes of stock of the Company entitled to vote, within the
meaning of Section 871(h)(3) of the Code, (ii) such Non-U.S. Holder is not a
controlled foreign corporation that is related, directly or indirectly, to the
Company through stock ownership, (iii) such Non-U.S. Holder is not a bank
receiving interest described in Section 881(c)(3)(A) of the Code, and (iv) the
certification requirements under Section 871(h) or Section 881(c) of the Code
and Treasury Regulations thereunder (summarized below) are satisfied,

A Non-U.S. Holder of a note will not be subject to U.S. income tax on gain
realized on the sale, exchange or other disposition of such note unless (i)
such Non-U.S. Holder is an individual who is present in the U.S. for 183 days
or more in the taxable year of sale, exchange or other disposition, and
certain conditions are met, (ii) such gain is effectively connected with the
conduct by the Non-U.S. Holder of a trade or business in the U.S. and, if
certain tax treaties apply, is attributable to a U.S. permanent establishment
maintained by the Non-U.S. Holder, or (iii) the Non-U.S. Holder is subject to
Code provisions applicable to certain U.S. expatriates.

A note held by an individual who is not a citizen or resident of the U.S.
at the time of his death will not be subject to U.S. estate tax as a result of
such individual's death, provided that, at the time of such individual's

132
<PAGE>

death, the individual does not own, actually or constructively, 10% or more of
the total combined voting power of all classes of stock of the Company
entitled to vote and payments with respect to such note would not have been
effectively connected with the conduct by such individual of a trade or
business in the U.S.

To satisfy the certification requirements referred to above, (i) the
beneficial owner of a note must certify, under penalties of perjury, to the
Company or its paying agent, as the case may be, that such owner is a Non-U.S.
Holder and must provide such owner's name and address and U.S. taxpayer
identification number ("TIN") (which certification may be made on IRS
Form W-8BEN), if any, or (ii) a securities clearing organization, bank or other
financial institution that holds customers securities in the ordinary course
of its trade or business (a "Financial Institution") and holds the note on
behalf of the beneficial owner thereof must certify, under penalties of
perjury, to the Company or its paying agent, as the case may be, that such
certificate has been received from the beneficial owner and must furnish the
payor with a copy thereof.

For payments made after December 31, 2000, in the case of notes held by a
foreign partnership that is not a withholding foreign partnership, the
partnership, in addition to providing an IRS Form W-8IMY, must attach an IRS
Form W-8BEN received from each partner.

If a Non-U.S. Holder of a note is engaged in a trade or business in the
U.S. and if interest on the note or gain realized on the sale, exchange or
other disposition of the note is effectively connected with the conduct of
such trade or business (and, if a tax treaty applies, is attributable to a
U.S. permanent establishment maintained by the Non-U.S. Holder in the U.S.),
the Non-U.S. Holder, although exempt from U.S. withholding tax (provided that
certification requirements are met), will generally be subject to regular U.S.
income tax on such interest or gain in the same manner as if it were a U.S.
Holder. In lieu of the certificate described above, such a Non-U.S. Holder
will be required to provide the Company with a properly executed IRS Form 4224
(or, after December 31, 2000, an IRS Form W-8ECI) in order to claim an
exemption from withholding tax. In addition, if such Non-U.S. Holder is a
foreign corporation, it may be subject to a branch profits tax equal to 30%
(or such lower rate provided by an applicable treaty) of its effectively
connected earnings and profits for the taxable year, subject to certain
adjustments.

Non-U.S. Holders should consult with their tax advisors regarding U.S. and
foreign tax consequences with respect to the notes.

Backup Withholding and Information Reporting

Backup withholding at a rate of 31% will apply to payments made in respect
of a note to a holder that is not an "exempt recipient" and that fails to
provide a TIN or certificate of exempt status or fails to report in full
dividend or interest income in the manner required. Generally, individuals are
not exempt recipients, whereas corporations and certain other entities are
exempt recipients. Payments made in respect of a note must be reported to the
Internal Revenue Service, unless the holder is an exempt recipient or
otherwise establishes an exemption.

In the case of payments of interest on a note to a Non-U.S. Holder, backup
withholding and information reporting will not apply if such Non-U.S. Holder
has furnished a certificate of foreign status on IRS Form W-8BEN, W-8ECI or
W-8IMY or otherwise establishes an exemption (provided that neither the Company
nor a paying agent has actual knowledge, or after December 31, 2000, reason to
know, that the holder is a U.S. Holder or that the conditions of any other
exemption are not in fact satisfied).

Payments of the proceeds of the sale of a note to or through a foreign
office of a broker that is (i) a U.S. person, (ii) a controlled foreign
corporation, (iii) a foreign person 50% or more of whose gross income from all
sources for the three-year period ending with the close of its taxable year
preceding the payment was effectively connected with the conduct of a trade or
business within the U.S. or (iv) with respect to payments made after December
31, 2000, foreign partnerships with certain connections to the U.S., are
currently subject to certain information reporting requirements, but not
backup withholding, unless the payee is an exempt recipient or such broker has
evidence in its records that the payee is a Non-U.S. Holder and has no actual
knowledge or, after

133
<PAGE>

December 31, 2000, reason to know that such evidence is false and certain
other conditions are met. Payments of the proceeds of a sale of a note to or
through the U.S. office of a broker will be subject to information reporting
and backup withholding unless the payee certifies under penalties of perjury
as to his, her or its status as a Non-U.S. Holder and satisfies certain other
qualifications (and no agent or broker who is responsible for receiving or
reviewing such statement has actual knowledge or, after December 31, 2000,
reason to know that it is incorrect) and provides his, her or its name and
address or the payee otherwise establishes an exemption.

Non-U.S. Holders should consult their tax advisors regarding the
application of information reporting and backup withholding in their
particular situations, the availability of an exemption therefrom, and the
procedure for obtaining an exemption, if available. Any amounts withheld under
the backup withholding rules from a payment to a holder of a note will be
allowed as a refund or credit against such holder's U.S. federal income tax,
provided that the required information is furnished to the Internal Revenue
Service.

PLAN OF DISTRIBUTION

Reference is made to "The Exchange Offer" above for a description of the
exchange offer, including the purpose of the exchange offer, the basis upon
which the exchange notes are offered and expenses incurred in connection with
the exchange offer.

Each broker-dealer that receives exchange notes for its own account
pursuant to the exchange offer in exchange for original notes acquired by such
broker-dealer as a result of market making or other trading activities may be
deemed to be an "underwriter" within the meaning of the Securities Act and,
therefore, must deliver a prospectus meeting the requirements of the
Securities Act in connection with the exchange offer. Accordingly, each such
broker-dealer must acknowledge that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such
exchange notes. The Letter of Transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. This prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of
exchange notes received in exchange for original notes where such original
notes were acquired as a result of market-making activities or other trading
activities. We have agreed that, starting on the consummation of the exchange
offer, and ending on the close of business six months after the consummation
of the exchange offer, we will make this prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
such resale.

Neither we nor any of our affiliates has entered into any arrangement or
understanding with any broker-dealer to distribute the exchange notes and we
will not receive any proceeds from any sale of exchange notes by any broker-
dealers or any other persons. Exchange notes received by broker-dealers for
their own account pursuant to the exchange offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the exchange notes or a
combination of such methods of resale, at market prices prevailing at the time
of the resale, at prices related to such prevailing market prices or
negotiated prices. Any such resale may be made directly to purchasers or to or
through brokers or dealers who may receive compensation in the form of
commissions or concessions from any such broker or dealer and/or the purchaser
of any such exchange notes. Any broker or dealer that resells exchange notes
that were received by it for its own account pursuant to the exchange offer
and any broker or dealer that participates in a distribution of such exchange
notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of exchange notes and any
commissions or concessions received by any such person may be deemed to be
underwriting compensation under the Securities Act. The Letter of Transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

For a period of six months after the consummation of the exchange offer, we
will promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such
documents in the Letter of Transmittal. We have agreed to pay all expenses
incident to the exchange offer other than commissions or concessions of any
brokers or dealers and expenses of counsel for the underwriters or holders of
the exchange notes.

LEGAL MATTERS

Certain legal matters in connection with the exchange offer are being
passed upon for us by Kelley Drye & Warren LLP, New York, New York. Certain
attorneys in the firm of Kelley Drye & Warren own an aggregate of
approximately $385,000 of the partnership interests in KMC Telecommunications
L.P. which owns 40,000 shares of our common stock. Certain regulatory matters

In the event that we cease to be subject to the informational reporting
requirements of the Securities Exchange Act of 1934, we have agreed that, so
long as any notes remain outstanding, we will file with the Commission and
distribute to holders of the notes, copies of the financial information that
would have been contained in annual reports and quarterly reports, including
management's discussion and analysis of financial condition and results of
operations, that we would have been required to file with the Commission
pursuant to the Securities Exchange Act of 1934. Such financial information
will include annual reports containing consolidated financial statements and
notes thereto, together with an opinion thereon expressed by an independent
public accounting firm, as well as quarterly reports containing unaudited
condensed consolidated financial statements for the first three quarters of
each fiscal year. We will also make such reports available to prospective
purchasers of the notes, securities analysts and broker-dealers upon their
request. In addition, we have agreed that for so long as any of the notes
remain outstanding we will make available to any prospective purchaser of the
notes or beneficial owner of the notes in connection with any sale thereof the
information required by Rule 144A under the Securities Act of 1933, until such
time as we have either exchanged the notes for securities identical in all
material respects which have been registered under the Securities Act of 1933
or until such time as the holders thereof have disposed of the notes pursuant
to an effective registration statement.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 1999

1. Basis of Presentation and Organization

KMC Telecom Holdings, Inc. and its subsidiaries, KMC Telecom Inc., KMC
Telecom II, Inc., KMC Telecom III, Inc., KMC Telecom of Virginia, Inc., and
KMC Telecom Financing, Inc. are collectively referred to herein as the
Company. All significant intercompany accounts and transactions have been
eliminated in consolidation.

On July 1, 1999, the Company acquired all of the membership interests of
KMC Services LLC from Harold N. Kamine, the Chairman of our Board of
Directors, for nominal consideration. KMC Services LLC was formed to provide
services to the Company and its customers, initially offering a leasing
program for equipment physically installed at a customer's premises. The
acquisition was accounted for as a combination of entities under common
control, and no changes were made to the historical cost basis of KMC Services
LLC's assets. Accordingly, during the second quarter of 1999, the Company
reduced the carrying value of its $709,000 loan receivable from KMC Services
LLC to an amount equal to the value of KMC Services LLC's net assets at the
acquisition date. KMC Services LLC has been consolidated with the Company
since July 1, 1999.

The unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial reporting. Accordingly, they do not include certain
information and note disclosures required by generally accepted accounting
principles for annual financial reporting and should be read in conjunction
with the financial statements and notes thereto of KMC Telecom Holdings, Inc.
as of and for the year ended December 31, 1998.

The unaudited interim financial statements reflect all adjustments which
management considers necessary for a fair presentation of the results of
operations for these periods. The results of operations for the interim
periods are not necessarily indicative of the results for the full year.

The balance sheet of KMC Telecom Holdings, Inc. at December 31, 1998 was
derived from the audited consolidated balance sheet at that date.

2. Investments Held for Future Capital Expenditures

The Company has designated certain amounts as investments held for future
capital expenditures. As of September 30, 1999, the Company's investments held
for future capital expenditures consisted of cash equivalents (bank term
deposits and commercial paper with maturities of less than 90 days) of $69.8
million and debt securities (US government obligations and commercial bonds
due within 1 year) of $5.2 million. All debt securities have been designated
by the Company as held-to-maturity. Accordingly, such securities are recorded
in the accompanying financial statements at amortized cost. At September 30,
1999, the carrying value of such held-to-maturity debt securities approximated
their fair value.

6. Lucent Loan and Security Agreement

Lucent Loan and Security Agreement

KMC Telecom III entered into a Loan and Security Agreement (the "Lucent
Facility") dated February 4, 1999 with Lucent Technologies Inc. ("Lucent")
which provides for borrowings to be used to fund the acquisition of certain
telecommunications equipment and related expenses. The Lucent Facility
provides for an aggregate commitment of up to $600 million, of which $250
million is currently available to purchase Lucent products. Further, up to an
additional $350 million will be available upon (a) additional lenders
participating in the Lucent Facility and making commitments to make loans so
that Lucent's aggregate commitment does not exceed $250 million and (b) the
Company satisfying certain other requirements, the most significant of which
is KMC Holdings raising and contributing at least $300 million in high yield
debt or equity (other than disqualified stock) to KMC Telecom III. The Lucent
Facility places certain restrictions upon KMC Telecom III's ability to
purchase non-Lucent equipment with proceeds from such facility. At September
30, 1999, no amounts had been borrowed under the Lucent Facility.

Interest on borrowings under the Lucent Facility is charged, at the option
of KMC Telecom III, at a floating rate of LIBOR plus the "Applicable LIBOR
Margin", or at an alternative base rate plus the "Applicable Base Rate Margin"
(as defined). Such margins will be increased by 0.25% until KMC Telecom III
and its subsidiaries have completed systems in fourteen markets. If KMC
Telecom III defaults on any payment due under the Lucent Facility, the
interest rate will increase by four percentage points. If any other event of
default shall occur, the interest rate will be increased by two percentage
points. Interest on each LIBOR loan is payable on each LIBOR interest payment
date in arrears and interest on each base rate loan is payable quarterly in
arrears. KMC Telecom III must pay an annual commitment fee on the unused
portion of the Lucent Facility of 1.25%.

Loans borrowed under the Lucent Facility amortize in amounts based upon the
following percentages of the aggregate amount of the loans drawn under the
Lucent Facility:

<TABLE>

Payment Dates Amortization
------------- ----------------
<S> <C>
May 1, 2002--February 1, 2003........................... 2.5% per quarter

</TABLE>

KMC TELECOM HOLDINGS, INC.

NOTES TO UNAUDITED CONDENSED
CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

KMC Holdings has unconditionally guaranteed the repayment of up to $250
million under the Lucent Facility when such repayment is due, whether at
maturity, upon acceleration, or otherwise. KMC Telecom III Holdings, Inc.,
which owns the shares of KMC Telecom III and is wholly-owned by KMC Holdings,
has pledged the shares of KMC Telecom III to Lucent to collateralize its
obligations under the guaranty. In addition, KMC Telecom III has pledged all
of its assets to Lucent.

The Lucent Facility contains a number of affirmative and negative covenants
including, among others, covenants restricting the ability of KMC Telecom III
to consolidate or merge with any person, sell or lease assets not in the
ordinary course of business, sell or enter into any long term leases of dark
fiber, redeem stock, pay dividends or make any other payments (including
payments of principal or interest on loans) to KMC Holdings, create
subsidiaries, transfer any permits or licenses, or incur additional
indebtedness or act as guarantor for the debt of any other person, subject to
certain conditions.

KMC Telecom III is required to comply with certain financial tests and
maintain certain financial ratios, including, among others, a ratio of total
debt to contributed capital, certain minimum revenues, maximum EBITDA losses
and minimum EBITDA, maximum capital expenditures and minimum access lines, a
maximum total leverage ratio, a minimum debt service coverage ratio, a minimum
fixed charge coverage ratio and a maximum consolidated leverage ratio. The
covenants become more restrictive upon the earlier of (i) July 1, 2002 and
(ii) after KMC Telecom III achieves positive EBITDA for two consecutive fiscal
quarters.

Failure to satisfy any of the financial covenants will constitute an event
of default under the Lucent Facility, permitting the lenders to terminate the
commitment and/or accelerate payment of outstanding indebtedness. The Lucent
Facility also includes other customary events of default, including, without
limitation, a cross-default to other material indebtedness, material
undischarged judgments, bankruptcy, loss of a material franchise or material
license, breach of representations and warranties, a material adverse change,
and the occurrence of a change of control.

Waiver and Amendments to Financial Covenants

The Company obtained a waiver of compliance, for the quarter ended
September 30, 1999, with certain financial covenants (related to revenue and
EBITDA) contained in the Senior Secured Credit Facility (for a description of
the Senior Secured Credit Facility, see Note 6 of the Notes to the
Consolidated Financial Statements in the Company's Annual Report on Form 10-K
for the year ended December 31, 1998). In addition, the EBITDA covenant was
amended for the fourth quarter of 1999 to a level which the Company expects to
achieve.

The Company has received a signed commitment from Lucent to refinance the
existing Lucent Facility upon terms which would involve the provision of
additional funding to the Company and the resetting of the financial covenants
for periods after the fourth quarter of 1999. The Company is currently engaged
in discussions with the agents for the lenders under the Senior Secured Credit
Facility which presently contemplate comparable amendments to the financial
covenants in the Senior Secured Credit Facility. The Company believes that
these negotiations will lead to definitive agreements during the first quarter
of 2000. If, however, the Company is not successful in completing the
negotiations as presently contemplated and amending the financial covenants in
the Senior Secured Credit Facility and the Lucent Facility, the Company is
likely to fail to comply with one or more of the covenants presently contained
in those facilities for the quarter ended March 31, 2000, which failure,
unless waived, would constitute a default under those credit facilities. Given
that, as of this date, the Company has not yet signed definitive agreements
with Lucent and the agents for the lenders under the Senior Secured Credit
Facility implementing the foregoing refinancings, under applicable financial
accounting standards, the

F-8
<PAGE>

KMC TELECOM HOLDINGS, INC.

NOTES TO UNAUDITED CONDENSED
CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Company was required to reclassify the $125 million outstanding at September
30, 1999 under the Senior Secured Credit Facility as current liabilities in
the accompanying balance sheet. If, as expected, the Company successfully
completes the contemplated refinancings of the Senior Secured Credit Facility
and Lucent Facility prior to the issuance of its financial statements for the
year ended December 31, 1999, the applicable accounting standards will permit
it to classify the amounts outstanding under the Senior Secured Credit
Facility as long-term debt in its balance sheet as of December 31, 1999. A
covenant default under the Senior Secured Credit Facility or the Lucent
Facility is not an automatic default under the Company's other outstanding
indebtedness but, under certain circumstances, may become one, depending upon
the actions of the lenders under the Senior Secured Credit Facility and Lucent
Facility.

7. Interest Rate Swap Agreement

The Company has entered into an interest rate swap agreement with a
commercial bank to reduce the impact of changes in interest rates on its
outstanding variable rate debt. The agreement effectively fixes the Company's
interest rate on the $125 million of outstanding variable rate borrowings
under the Senior Secured Credit Facility due 2007. The interest rate swap
agreement terminates in April 2004. The Company is exposed to credit loss in
the event of nonperformance by the other party to the interest rate swap
agreement. However, the Company does not anticipate nonperformance by the
counterparty.

8. Preferred Stock and Warrant Issuances

Series E Preferred Stock

On February 4, 1999, the Company issued 25,000 shares of Series E Senior
Redeemable, Exchangeable, PIK Preferred Stock (the "Series E Preferred Stock")
to Newcourt Commercial Finance Corporation ("Newcourt Finance"), generating
aggregate gross proceeds of $22.9 million. On April 30, 1999, the Company
issued an additional 35,000 shares of Series E Preferred Stock for gross
proceeds of $25.9 million. The Series E Preferred Stock has a liquidation
preference of $1,000 per share and an annual dividend equal to 14.5% of the
liquidation preference, payable quarterly. On or before January 15, 2004, the
Company may pay dividends in cash or in additional fully paid and
nonassessable shares of Series E Preferred Stock. After January 15, 2004,
dividends must be paid in cash, subject to certain conditions. Unpaid
dividends accrue at the dividend rate of the Series E Preferred Stock,
compounded quarterly. On April 15, 1999 and July 15, 1999, the Company issued
695 shares and 1,986 shares, respectively, of Series E Preferred Stock to pay
the dividends due for such periods.

The Series E Preferred Stock must be redeemed on February 1, 2011, subject
to the legal availability of funds therefor, at a redemption price, payable in
cash, equal to the liquidation preference thereof on the redemption date, plus
all accumulated and unpaid dividends to the date of redemption. After April
15, 2004, the Series E Preferred Stock may be redeemed, in whole or in part,
at the option of the Company, at a redemption price equal to 110% of the
liquidation preference of the Series E Preferred Stock plus all accrued and
unpaid dividends to the date of redemption. The redemption price declines to
an amount equal to 100% of the liquidation preference as of April 15, 2007.

In addition, on or prior to April 15, 2002, the Company may, at its option,
redeem up to 35% of the aggregate liquidation preference of Series E Preferred
Stock with the proceeds of sales of its capital stock at a redemption price
equal to 110% of the liquidation preference on the redemption date plus
accrued and unpaid dividends.

The holders of Series E Preferred Stock have voting rights in certain
circumstances. Upon the occurrence of a change of control, the Company will be
required to make an offer to repurchase the Series E Preferred Stock

F-9

NOTES TO UNAUDITED CONDENSED
CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

for cash at a purchase price of 101% of the liquidation preference thereof,
together with all accumulated and unpaid dividends to the date of purchase.

The Series E Preferred Stock is not convertible. The Company may, at the
sole option of the Board of Directors (out of funds legally available),
exchange all, but not less than all, of the Series E Preferred Stock then
outstanding, including any shares of Series E Preferred Stock issued as
payment for dividends, for a new series of subordinated debentures (the
"Exchange Debentures") issued pursuant to an exchange debenture indenture. The
holders of Series E Preferred Stock are entitled to receive on the date of any
such exchange, Exchange Debentures having an aggregate principal amount equal
to (i) the total of the liquidation preference for each share of Series E
Preferred Stock exchanged, plus (ii) an amount equal to all accrued but unpaid
dividends payable on such share.

Series F Preferred Stock

On February 4, 1999, the Company issued 40,000 shares of Series F Senior
Redeemable, Exchangeable, PIK Preferred Stock (the "Series F Preferred Stock")
to Lucent and Newcourt Finance, generating aggregate gross proceeds of $38.9
million. The Series F Preferred Stock has a liquidation preference of $1,000
per share and an annual dividend equal to 14.5% of the liquidation preference,
payable quarterly. The Company may pay dividends in cash or in additional
fully paid and nonassessable shares of Series F Preferred Stock. On April 15,
1999 and July 15, 1999, the Company issued 1,112 shares and 1,486 shares,
respectively, of Series F Preferred Stock to pay the dividends due for such
period.

The Series F Preferred Stock may be redeemed at any time, in whole or in
part, at the option of the Company, at a redemption price equal to 110% of the
liquidation preference on the redemption date plus an amount in cash equal to
all accrued and unpaid dividends thereon to the redemption date. Upon the
occurrence of a change of control, the Company will be required to make an
offer to purchase the Series F Preferred Stock for cash at a purchase price of
101% of the liquidation preference thereof, together with all accumulated and
unpaid dividends to the date of purchase.

The holders of Series F Preferred Stock have voting rights under certain
circumstances.

Upon the earlier of (i) the date that is sixty days after the date on which
the Company closes an underwritten primary offering of at least $200 million
of its Common Stock, pursuant to an effective registration statement under the
Securities Act or (ii) February 4, 2001, any outstanding Series F Preferred
Stock will automatically convert into Series E Preferred Stock, on a one for
one basis.

The Company may, at the sole option of the Board of Directors (out of funds
legally available), exchange all, but not less than all, of the Series F
Preferred Stock then outstanding, including any shares of Series F Preferred
Stock issued as payment for dividends, for Exchange Debentures. The holders of
Series F Preferred Stock are entitled to receive on the date of any such
exchange, Exchange Debentures having an aggregate principal amount equal to
(i) the total of the liquidation preference for each share of Series F
Preferred Stock exchanged, plus (ii) an amount equal to all accrued but unpaid
dividends payable on such share.

Warrants

In connection with the February 4, 1999 issuances of the Series E Preferred
Stock and the Series F Preferred Stock, warrants to purchase an aggregate of
24,660 shares of Common Stock were sold to Newcourt Finance and Lucent. The
aggregate gross proceeds from the sale of these warrants was approximately
$3.2 million. These warrants, at an exercise price of $.01 per share, are
exercisable from February 4, 2000 through February 1, 2009.

In addition, the Company also delivered to the Warrant Agent certificates
representing warrants to purchase an aggregate of an additional 107,228 shares
of Common Stock at an exercise price of $.01 per share (the "Springing
Warrants"). The Springing Warrants may become issuable under the circumstances
described in the following paragraph.

If the Company fails to redeem all shares of Series F Preferred Stock prior
to the date (the "Springing Warrant Date") which is the earlier of (i) the
date that is sixty days after the date on which the Company closes an
underwritten primary offering of at least $200 million of its Common Stock
pursuant to an effective registration statement under the Securities Act or
(ii) February 4, 2001, the Warrant Agent is authorized to issue the Springing
Warrants to the Eligible Holders (as defined in the warrant agreement) of the
Series E and Series F Preferred Stock. In the event the Company has redeemed
all outstanding shares of Series F Preferred Stock prior to the Springing
Warrant Date, the Springing Warrants will not be issued and the Warrant Agent
will return the certificates to the Company. To the extent the Company
exercises its option to exchange all of the Series F Preferred Stock for
Exchange Debentures prior to the Springing Warrant Date, the Springing
Warrants will not become issuable. Therefore, as the future issuance of the
Springing Warrants is entirely within the control of the Company and the
likelihood of their issuance is deemed to be remote, no value has been
ascribed to the Springing Warrants.

In connection with the April 30, 1999 issuance of additional shares of the
Series E Preferred Stock, warrants to purchase an aggregate of 60,353 shares
of Common Stock were issued to Newcourt Finance and First Union. The aggregate
gross proceeds from the sale of these warrants was approximately $9.1 million.
These warrants, at an exercise price of $.01 per share, are exercisable from
February 4, 2000 through February 1, 2009.

9. Service Revenues

The Company provides on-net switched and dedicated services and resells
switched services previously purchased from the incumbent local exchange
carrier. On-net services include both services provided through direct
connections to our own networks and services provided by means of unbundled
network elements leased from the incumbent local exchange carrier.

The Company's service revenues consist of the following (in thousands):

Arbitration Award

During the second quarter of 1999, the company recorded a $4.3 million
charge to other expense in connection with an unfavorable arbitration award.
The net amount due under the terms of the award was paid in full in June 1999.

Redemption Rights

Pursuant to a stockholders agreement, certain of the Company's stockholders
and warrant holders have "put rights" entitling them to have the Company
repurchase their preferred and common shares and redeemable common stock
warrants for the fair value of such securities if no Liquidity Event (defined
as (i) an initial public offering with gross proceeds of at least $40 million,
(ii) the sale of substantially all of the stock or assets of the Company or
(iii) the merger or consolidation of the Company with one or more other
corporations) has taken place by the later of (x) October 22, 2003 or (y) 90
days after the final maturity date of the Senior Discount Notes. The
restrictive covenants of the Senior Discount Notes limit the Company's ability
to repurchase such securities. All of the securities subject to such "put
rights" are presented as redeemable equity in the accompanying balance sheets.

The redeemable preferred stock, redeemable common stock and redeemable
common stock warrants, which are subject to the stockholders agreement, are
being accreted up to their fair market values from their respective issuance
dates to their earliest potential redemption date (October 22, 2003). At
September 30, 1999, the aggregate redemption value of the redeemable equity
was approximately $235 million, reflecting per share redemption amounts of
$897 for the Series A Preferred Stock, $352 for the Series C Preferred Stock
and $185 for the redeemable common stock and redeemable common stock warrants.

11. Net Loss Per Common Share

The following table sets forth the computation of net loss per common
share-basic (in thousands, except share and per share amounts):

12. Louisiana Reciprocal Revenue

During 1998 and the first nine months of 1999 the Company recognized
revenue which it believed was due from incumbent local exchange carriers for
terminating local traffic of Internet service providers (ISPs). The Company
determined to recognize this revenue because, based upon all of the facts and
circumstances known at the time, including numerous state public service
commission and state and federal court decisions upholding competitive local
exchange carriers' entitlement to reciprocal compensation for such calls, that
realization of those amounts was reasonably assured. On October 13, 1999,
however, the Louisiana Public Service Commission ruled that local traffic to
ISPs in Louisiana is not eligible for reciprocal compensation. As a result of
that ruling, the Company determined that it could no longer conclude that
realization of amounts attributable to termination of local calls to ISPs in
Louisiana was reasonably assured. Accordingly, an adjustment was recorded to
reduce revenue in the 1999 Third Quarter, which reversed all reciprocal
revenue recognized related to ISP traffic in Louisiana for the entire year of
1998 and the first nine months of 1999. The adjustment amounted to $4.4
million, of which $1.1 million relates to the year ended December 31, 1998 and
$3.3 million relates to the nine months ended September 30, 1999.

The Company has been advised by its regulatory counsel that this decision
appears to be well out of the mainstream on the issue. To date, Louisiana is
the only state which has rendered a decision, pursuant to an existing
agreement, that has permitted an incumbent local exchange carrier to use a
competitive local exchange carriers' facilities to complete calls without
compensation to the competitive local exchange carrier. Thirty-three other
states have ruled that the originating carrier must compensate the terminating
carrier for such use. Many of these decisions have been affirmed by state and
federal courts on appeal and none have been reversed. The Company intends to
appeal the decision to the appropriate authority.

KMC TELECOM HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

KMC Telecom Holdings, Inc. ("KMC Holdings") is a holding company formed
during 1997 primarily to own all of the shares of its operating subsidiaries,
KMC Telecom Inc. ("KMC Telecom"), KMC Telecom II, Inc. ("KMC Telecom II"), KMC
Telecom III, Inc. ("KMC Telecom III") and KMC Telecom of Virginia Inc. On
September 22, 1997, the stockholders of KMC Telecom exchanged all of their KMC
Telecom common and preferred stock for equal numbers of shares of common and
preferred stock of KMC Holdings. The merger was accounted for as an exchange
of shares between entities under common control, and no changes were made to
the historical cost basis of KMC Telecom's net assets.

KMC Holdings and its direct and indirect wholly-owned subsidiaries, KMC
Telecom, KMC Telecom II, KMC Telecom III and KMC Telecom of Virginia, Inc. are
collectively referred to herein as the Company.

The predecessors to KMC Telecom, Kamine Multimedia Corp. and KMC Southeast
Corp. (the "Predecessors") were incorporated in the state of Delaware on May
10, 1994 and April 19, 1995, respectively, and all of the outstanding common
stock of each company was owned by Harold N. Kamine ("Kamine"). Effective May
23, 1996, Kamine Multimedia Corp. was merged into KMC Southeast Corp., and the
surviving corporation was renamed KMC Telecom Inc. The merger was accounted
for as a combination of entities under common control, and the net assets of
Kamine Multimedia Corp. were transferred at their historical cost in a manner
similar to that in pooling of interests accounting.

The Company is a facilities-based competitive local exchange carrier
("CLEC") providing telecommunications and data services to its customers;
principally business, government and institutional end-users, as well as
Internet service providers, long distance companies and wireless service
providers, primarily in the Southeastern and Midwestern United States.

2. Summary of Significant Accounting Policies

Basis of Presentation

As noted above, effective May 23, 1996, KMC Telecom was the successor
resulting from the merger of the Predecessors, and effective September 22,
1997, KMC Telecom became a wholly-owned subsidiary of KMC Holdings. The
accompanying financial statements include the consolidated financial position
and results of operations of KMC Holdings and its subsidiaries subsequent to
September 22, 1997, the results of operations of KMC Telecom from May 23,
1996, and the combined results of operations of the Predecessors from January
1, 1996. All significant intercompany transactions and balances have been
eliminated.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents.

Investments Held for Future Capital Expenditures

The Company has designated certain amounts as investments held for future
capital expenditures. As of December 31, 1998, the Company's investments held
for future capital expenditures consisted of cash equivalents (bank term
deposits and commercial paper with maturities of less than 90 days) of $11.2
million and debt securities (U.S. government obligations and commercial bonds
due within 1 year) of $16.7 million. All debt securities have been designated
by the Company as held-to-maturity. Accordingly, such securities are recorded

in the accompanying December 31, 1998 financial statements at amortized cost.
At December 31, 1998, the carrying value of such held-to-maturity debt
securities approximated their fair value.

Networks and Equipment

Networks and equipment are stated at cost, net of accumulated depreciation.
Depreciation is provided over the estimated useful lives of the respective
assets using the straight-line method for financial statement reporting
purposes.

The estimated useful lives of the Company's principal classes of assets are
as follows:

<TABLE>
<CAPTION>
Networks:
<S> <C>
Fiber optic systems.......................................... 20 years
Telecommunications equipment................................. 10 years
Furniture and fixtures......................................... 5 years
Leasehold improvements......................................... Life of lease
</TABLE>

Intangible Assets

Costs incurred in developing new networks or expanding existing networks,
including negotiation of rights-of-way and obtaining regulatory authorizations
are capitalized and amortized over the initial term of the agreements, which
generally range from 2 to 15 years. Costs incurred to obtain city franchises
are capitalized by the Company and amortized over the initial term of the
franchises, which generally range from 2 to 15 years.

Deferred Financing Costs

The Company capitalizes issuance costs related to its debt. Such costs are
amortized utilizing the interest method over the lives of the related debt.
The related amortization is included as a component of interest expense, and
amounted to $189,000, $561,000 and $2,279,000 for the years ended December 31,
1996, 1997 and 1998, respectively.

Other Assets

Other assets are comprised principally of non-refundable deposits for the
purchase of switching equipment, employee loans, security deposits and other
deposits.

Revenue Recognition

Revenue is recognized in the period the service is provided. Unbilled
revenue included in accounts receivable represents revenue earned for services
which will be billed in the succeeding month and totaled $1,272,000 at
December 31, 1998. The Company generally invoices customers one month in
advance for recurring services resulting in deferred revenue of $1,187,000 at
December 31, 1998.

Net Loss Per Common Share

Earnings per share are calculated in accordance with FASB Statement No.
128, Earnings per Share ("Statement 128"). All earnings per share amounts for
all periods have been presented in accordance with the provisions of Statement
128. Diluted earnings per share have not been presented for any period, as the
impact of including outstanding options and warrants would be anti-dilutive.
The Predecessors' earnings per share have been computed as if the May 23, 1996
merger had occurred as of January 1, 1996.

Income Taxes

The Company uses the liability method to account for income taxes. Deferred
taxes are recorded based upon differences between the financial statement and
tax basis of assets and liabilities.

Advertising Costs

Advertising costs are included in selling, general and administrative
expenses and charged to expense as incurred. For the years ended December 31,
1997 and 1998, such costs were $66,000 and $2,769,000, respectively.

Use of Estimates

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

Impairment of Long-Lived Assets

The Company records impairment losses on long-lived assets used in
operations or expected to be disposed of when events and circumstances
indicate that the cash flows expected to be derived from those assets are less
than the carrying amounts of those assets. No such events and circumstances
have occurred.

Stock-Based Compensation

As permitted by FASB Statement No. 123, Accounting for Stock-Based
Compensation ("Statement 123"), the Company has elected to follow Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees
("APB 25") and related interpretations in accounting for its employee stock-
based compensation. Under APB 25, no compensation expense is recognized at the
time of option grant if the exercise price of the employee stock option is
fixed and equals or exceeds the fair market value of the underlying common
stock on the date of grant, and the number of shares to be issued pursuant to
the exercise of such option are known and fixed at the grant date. As more
fully described in Note 7, the Company's outstanding stock options are not
considered fixed options under APB 25. The Company accounts for non-employee
stock-based compensation in accordance with Statement 123.

Comprehensive Income

In 1998, the Company adopted FASB Statement No. 130, Reporting
Comprehensive Income, which established new rules for the reporting and
display of comprehensive income and its components in a full set of general-
purpose financial statements. This statement has no effect on the Company's
financial statement presentation because the Company presently has no items of
comprehensive income.

Segment Reporting

In 1998, the Company adopted FASB Statement No. 131, Disclosures About
Segments of an Enterprise and Related Information ("Statement 131"). Statement
131 uses a management approach to report financial and descriptive information
about an entity's operating segments. Operating segments are revenue-producing
components of an enterprise for which separate financial information is
produced internally for the entity's management. Under this definition, the
Company operated within a single segment for all periods presented.

Recently Issued Accounting Pronouncements

In January 1998, the Accounting Standards Executive Committee of the AICPA
issued Statement of Position 98-5, Reporting on the Costs of Start-Up
Activities, which is effective for fiscal years beginning after December 15,
1998. This statement requires costs of start-up activities to be expensed as
incurred. The Company does not anticipate that the adoption of this statement
will have any effect on its results of operations or financial position,
because the Company currently expenses such costs.

In June 1998, the FASB issued Statement No. 133, Accounting for Derivative
Instruments and Hedging Activities. The Company expects to adopt the new
Statement effective January 1, 2000. This statement will require the Company
to recognize all derivatives on the balance sheet at fair value. The Company
does not anticipate that the adoption of this statement will have a
significant effect on its results of operations or financial position, because
the Company presently has no derivatives.

6. Long-Term Debt

Senior Secured Credit Facility

On September 22, 1997, KMC Telecom and KMC Telecom II entered into an
Amended and Restated Loan and Security Agreement (the "AT&T Facility") with
AT&T Commercial Finance Corporation ("AT&T Finance") which provided for
borrowings up to an aggregate of $70 million.

On December 22, 1998, KMC Telecom, KMC Telecom II and KMC Telecom of
Virginia (the "Borrowers"), refinanced and expanded the AT&T Facility by
entering into a Loan and Security Agreement (the "Senior Secured Credit
Facility") with AT&T Finance, First Union National Bank, General Electric
Capital Corporation ("GECC") and Canadian Imperial Bank of Commerce (the
"Lenders"). Under the Senior Secured Credit Facility, the Lenders agreed to
lend the Borrowers up to an aggregate of $250 million initially to be used for
the construction and expansion of fiber optic telecommunications networks in
certain markets and for payment of transaction fees and expenses and, subject
to the attainment of certain financial conditions, for working capital and
general corporate purposes.

The Senior Secured Credit Facility includes a $175 million eight year
revolving loan (the "Revolver") and a $75 million eight and one half year term
loan (the "Term Loan"). At December 31, 1998, an aggregate of $41.4 million
was outstanding under this facility.

The Senior Secured Credit Facility will mature no later than July 1, 2007.
The outstanding principal balance of the Term Loan is payable in twenty
consecutive quarterly installments of $188,000 beginning on April 1, 2002 and
two final installments of $35.6 million each on April 1, 2007 and July 1,
2007. The aggregate commitment of the Lenders under the Revolver will be
reduced on each payment date beginning April 1, 2002. The initial quarterly
commitment reductions are 2.5%, increasing to 5% on April 1, 2003 and further
increasing to 7.5% on April 1, 2006. Commencing on April 1, 2002, the
aggregate Revolver commitment will be further reduced by an amount equal to
50% of excess operating cash flows (as defined in the facility) for the prior
fiscal year until the Borrowers achieve and maintain for at least two
consecutive fiscal quarters certain financial conditions. Additionally, in the
event certain principal amounts due under the Revolver are repaid and not
reborrowed within 120 days of such repayment, then the aggregate commitment
under the Revolver will be reduced by such amount.

Borrowings under the Senior Secured Credit Facility will bear interest
payable at the Borrowers' option, at (a) the "Applicable Base Rate Margin"
(which generally ranges from 1.75% to 3.25%) plus the greater of (i) the
administrative agent's prime rate or (ii) the overnight federal funds rate
plus .5% or (b) the "Applicable LIBOR Margin" (which generally ranges from
2.75% to 4.25%) plus LIBOR, as defined. If the Borrowers default on any
interest or principal payment due under the Senior Secured Credit Facility,
the interest rate will increase by four percentage points. If any other event
of default shall occur, the interest rate will be increased by two

F-23

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

percentage points. Interest on each LIBOR loan is payable on each LIBOR
interest payment date in arrears and interest on each base rate loan is
payable quarterly in arrears. Interest on borrowings outstanding
at December 31, 1998 was based on LIBOR, and the Borrowers were being charged
at an annual rate of 9.38%. The Borrowers must pay an annual commitment fee on
the unused portion of the Senior Secured Credit Facility ranging from .75% to
1.25%.

KMC Holdings has unconditionally guaranteed the repayment of the Senior
Secured Credit Facility when such repayment is due, whether at maturity, upon
acceleration, or otherwise. KMC Holdings has pledged the shares of each of the
Borrowers to the Lenders to collateralize its obligations under the guaranty.
In addition, the Borrowers have each pledged all of their assets to the
Lenders.

The Senior Secured Credit Facility contains a number of affirmative and
negative covenants including, among others, covenants restricting the ability
of the Borrowers to consolidate or merge with any person, sell or lease assets
not in the ordinary course of business, sell or enter into long term leases of
dark fiber, redeem stock, pay dividends or make any other payments (including
payments of principal or interest on loans) to KMC Holdings, create
subsidiaries, transfer any permits or licenses, or incur additional
indebtedness or act as guarantor for the debt of any person, subject to
certain conditions.

The Borrowers are required to comply with certain financial tests and
maintain certain financial ratios, including, among others, a ratio of total
debt to contributed capital, certain minimum revenues, maximum EBITDA losses
and minimum EBITDA, maximum capital expenditures and minimum access lines, a
maximum total leverage ratio, a minimum debt service coverage ratio, a minimum
fixed charge coverage ratio and a maximum consolidated leverage ratio. The
covenants become more restrictive upon the earlier of (i) June 30, 2001 and
(ii) after the Borrowers achieve positive EBITDA on a combined basis for two
consecutive fiscal quarters.

Failure to satisfy any of the financial covenants will constitute an event
of default under the Senior Secured Credit Facility permitting the Lenders,
after notice, to terminate the commitment and/or accelerate payment of
outstanding indebtedness. The Senior Secured Credit Facility also includes
other customary events of default, including, without limitation, a cross-
default to other material indebtedness, material undischarged judgments,
bankruptcy, loss of a material franchise or material license, breach of
representations and warranties, a material adverse change, and the occurrence
of a change of control.

Senior Discount Notes

On January 29, 1998, KMC Holdings sold 460,800 units, each unit consisting
of a 12 1/2% senior discount note with a principal amount at maturity of
$1,000 due 2008 pursuant to the Senior Discount Note Indenture between KMC
Holdings and the Chase Manhattan Bank, as trustee (the "Senior Discount
Notes"), and one warrant to purchase .21785 shares of Common Stock of KMC
Holdings at an exercise price of $.01 per share. The gross and net proceeds of
the offering were approximately $250.0 million and $236.4 million,
respectively. A substantial portion of the net proceeds of the offering have
been loaned by KMC Holdings to its subsidiaries. On August 11, 1998, KMC
Holdings consummated an offer to exchange the notes issued on January 29, 1998
for $460.8 million aggregate principal amount at maturity of notes that had
been registered under the Securities Act of 1933 (as used below and elsewhere
herein, "Senior Discount Notes" includes the original notes and the exchange
notes).

The Senior Discount Notes are unsecured, unsubordinated obligations of the
Company and mature on February 15, 2008. The Senior Discount Notes were sold
at a substantial discount from their principal amount at maturity, and there
will not be any payment of interest on the Senior Discount Notes prior to
August 15, 2003. The Senior Discount Notes will fully accrete to face value on
February 15, 2003. From and after February 15,

F-24
<PAGE>

KMC TELECOM HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

2003, the Senior Discount Notes will bear interest, which will be payable in
cash, at the rate of 12.5% per annum on February 15 and August 15 of each
year, commencing August 15, 2003. The Company is accreting the initial
carrying value of the Senior Discount Notes to their aggregate face value over
the term of the debt at its effective interest rate of 13.7%.

The Senior Discount Notes are redeemable, at the Company's option, in whole
or in part, on or after February 15, 2003 and prior to maturity, at redemption
prices equal to 106.25% of the aggregate principal amount at maturity, plus
accrued and unpaid interest, if any, to the redemption date, declining to 100%
of the aggregate principal amount at maturity, plus accrued and unpaid
interest as of February 15, 2006.

In addition, at any time prior to April 15, 2000, the Company may redeem up
to 35% of the aggregate principal amount at maturity of the Senior Discount
Notes with the net proceeds from the sale of common equity at a redemption
price of 112.50% of their accreted value on the redemption date.

The indebtedness evidenced by the Senior Discount Notes ranks pari passu in
right of payment with all existing and future unsubordinated, unsecured
indebtedness of KMC Holdings and senior in right of payment to all existing
and future subordinated indebtedness of KMC Holdings. However, KMC Holdings is
a holding company and the Senior Discount Notes are, therefore, effectively
subordinated to all existing and future liabilities (including trade payables)
of its subsidiaries.

Within 30 days of the occurrence of a Change of Control (as defined in the
Senior Discount Note Indenture), the Company must offer to purchase for cash
all Senior Discount Notes then outstanding at a purchase price equal to 101%
of the accreted value thereof, plus accrued interest. The Company's ability to
comply with this requirement is subject to certain restrictions contained in
the Senior Secured Credit Facility.

The Senior Discount Note Indenture contains events of default, including,
but not limited to, (i) defaults in the payment of principal, premium or
interest, (ii) defaults in compliance with covenants contained in the Senior
Discount Note Indenture, (iii) cross defaults on more than $5 million of other
indebtedness, (iv) failure to pay more than $5 million of judgments that have
not been stayed by appeal or otherwise and (v) the bankruptcy of KMC Holdings
or certain of its subsidiaries. The Senior Discount Note Indenture restricts,
among other things, the ability of KMC Holdings to incur additional
indebtedness, create liens, engage in sale-leaseback transactions, pay
dividends or make distributions in respect of capital stock, make investments
or certain other restricted payments, sell assets of KMC Holdings, redeem
capital stock, issue or sell stock of restricted subsidiaries, enter into
transactions with stockholders or affiliates or effect a consolidation or
merger. The Senior Discount Note Indenture permits KMC Holdings' subsidiaries
to be deemed unrestricted subsidiaries and, thus, not subject to the
restrictions of the Senior Discount Note Indenture.

The Senior Discount Notes are "applicable high yield discount obligations"
("AHYDOs"), as defined in the Internal Revenue Code of 1986, as amended. Under
the rules applicable to AHYDOs, a portion of the original issue discount
("OID") that accrues on the Senior Discount Notes will not be deductible by
the Company at any time. Any remaining OID on the Senior Discount Notes will
not be deductible by the Company until such OID is paid.

Other Indebtedness

On September 22, 1997, KMC Telecom and KMC Telecom II obtained a
subordinated term loan (the "Supplemental AT&T Facility") from AT&T Finance
with an original principal amount of $10 million. The Supplemental AT&T
Facility was, by its terms, due in full upon the closing of a debt offering
with gross cash proceeds of at least $50 million. On January 29, 1998, the
entire $10 million outstanding under this facility was repaid in full with a
portion of the proceeds of the Company's issuance of Senior Discount Notes and
warrants.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

During 1996, KMC Telecom issued convertible secured notes payable
aggregating $11,894,000 and $106,000 to two entities, Nassau Capital Partners
L.P. and NAS Partners I L.L.C. ("Nassau Capital" and "Nassau Partners",
respectively, collectively referred to as "Nassau") (such notes are
collectively referred to herein as the "Convertible Notes".) On January 21,
1997, the Convertible Notes, including accrued interest through that date,
aggregating approximately $12,380,000 were converted into 123,800 shares of
Series A Cumulative Convertible Preferred Stock of KMC Telecom (such stock was
subsequently exchanged for an equal number of shares of Series A Preferred
Stock of KMC Holdings on September 22, 1997).

7. Redeemable and Nonredeemable Equity

KMC Telecom Preferred Stock

On January 21, 1997, the Convertible Notes were converted into 123,800
shares of Series A Cumulative Convertible Preferred Stock of KMC Telecom with
an aggregate liquidation value of $12,380,000. Effective September 22, 1997,
all of the shares of Series A Cumulative Convertible Preferred Stock of KMC
Telecom were exchanged for an equal number of shares of Series A Cumulative
Convertible Preferred Stock of KMC Holdings.

Pursuant to an agreement with Nassau, all dividends accumulated on the
Series A Cumulative Convertible Preferred Stock of KMC Telecom through
September 22, 1997 ($592,000) were paid upon the closing of KMC Holdings'
issuance of Senior Discount Notes and warrants on January 29, 1998.

Series A Preferred Stock

There are 123,800 shares of Series A Cumulative Convertible Preferred Stock
of KMC Holdings ("Series A Preferred Stock") authorized and outstanding.
Series A Preferred Stock has a liquidation preference of $100 per share and an
annual dividend equal to 7.0% of the liquidation preference, payable
quarterly, when and if declared by the Board of Directors out of funds legally
available therefor. Unpaid dividends accumulate and the unpaid amount
increases at the annual rate of 7.0%, compounded quarterly. All accumulated
but unpaid dividends will be paid upon the occurrence of a Realization Event
(defined as (i) an initial public offering with gross proceeds of at least $40
million or (ii) sale of substantially all the assets or stock of the Company
or the merger or consolidation of the Company into one or more other
corporations). As of December 31, 1998, dividends in arrears on the Series A
Preferred Stock aggregated $1,144,000. Notwithstanding the foregoing, pursuant
to an agreement among Nassau and the Company, Nassau has agreed to forego the
payment of dividends from September 22, 1997 through the date on which Nassau
disposes of its interest in the Company; provided that at the time of such
disposition, Nassau has received not less than a 10% annual compound rate of
return during the period it held the Series A Preferred Stock.

Series A Preferred Stock is convertible into Common Stock at a conversion
price equal to $20.63 per share of Common Stock, subject to adjustment upon
the occurrence of certain events. Holders of Series A Preferred Stock may
convert all or part of such shares to Common Stock. Upon conversion, subject
to the aforementioned agreement to forego the payment of dividends, the
holders are entitled to receive a cash payment of the accumulated but unpaid
dividends; provided, however, that the Company may substitute common shares
having a fair market value equal to the amount of such cash payment if the
conversion occurs before a Realization Event. Series A Preferred Stock will
automatically convert into Common Stock upon the occurrence of a Qualified
Public Offering (defined as the first sale of Common Stock pursuant to a
registration statement filed under the Securities Act of 1933 in which the
Company receives gross proceeds of at least $40 million, provided that the per
share price at which such shares are sold in such offering is at least four
times the conversion price of the Series A Preferred Stock).

KMC TELECOM HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

The holders of Series A Preferred Stock, except as otherwise provided in
the Company's Certificate of Incorporation, are entitled to vote on all
matters voted on by holders of Common Stock. Each share of Series A Preferred
Stock is entitled to a number of votes equal to the number of shares of Common
Stock into which such share is convertible. Without the prior consent of two-
thirds of the shares of Series A Preferred Stock, among other things, the
Company may not increase the number of shares of preferred stock (of whatever
series) authorized for issuance, or declare or pay any dividends on shares of
Common Stock or other junior shares. As discussed under "Redemption Rights"
below, the holders of Series A Preferred Stock have certain redemption rights.
Accordingly, such stock has been reflected as redeemable equity in the
accompanying financial statements.

Series C Preferred Stock

There are 350,000 shares of Series C Cumulative Convertible Preferred Stock
of KMC Holdings ("Series C Preferred Stock") authorized, of which 175,000
shares are outstanding at December 31, 1998. 150,000 of such shares were
issued in November 1997, generating aggregate gross proceeds of $15 million
and the remaining 25,000 shares were issued in January 1998 upon the
conversion of an equal number of shares of Series D Preferred Stock. Series C
Preferred Stock has a liquidation preference of $100 per share and an annual
dividend equal to 7.0% of the liquidation preference, payable quarterly, when
and if declared by the Board of Directors out of funds legally available
therefor. Unpaid dividends accumulate and the unpaid amount increases at the
annual rate of 7.0%, compounded quarterly. All accumulated but unpaid
dividends will be paid upon the occurrence of a Realization Event. As of
December 31, 1998, dividends in arrears on the Series C Preferred Stock
aggregated $1,458,000. Notwithstanding the foregoing, pursuant to the Purchase
Agreement among the Company, Nassau, GECC and CoreStates Holdings, Inc.
("CoreStates"), each current holder of Series C Preferred Stock has agreed to
forego the payment of dividends that accumulate during the period from
issuance through the date on which such holder disposes of its interest in the
Company; provided that at the time of such disposition, it has received not
less than a 10% annual compound rate of return during such period.

Series C Preferred Stock is convertible into Common Stock at a conversion
price equal to (i) from the date of initial issuance to the date which is 30
months after the date of such initial issuance, $52.50 per share of Common
Stock and (ii) from and after the date which is 30 months after the date of
initial issuance, $42.18; provided that both such amounts are subject to
adjustment upon the occurrence of certain events. Holders of Series C
Preferred Stock may convert all or part of such shares to Common Stock. Upon
conversion, subject to the aforementioned agreement to forego the payment of
dividends, the holders are entitled to receive a cash payment of the
accumulated but unpaid dividends; provided, however, that the Company may
substitute common shares having a fair market value equal to the amount of
such cash payment if the conversion occurs before a Realization Event. Series
C Preferred Stock will automatically convert into Common Stock upon the
occurrence of a Qualified Public Offering.

The holders of Series C Preferred Stock, except as otherwise provided in
the Company's Certificate of Incorporation, are entitled to vote on all
matters voted on by holders of Common Stock. Each share of Series C Preferred
Stock is entitled to a number of votes equal to the number of shares of Common
Stock into which such share is convertible. Without the prior consent of two-
thirds of the shares of Series C Preferred Stock, among other things, the
Company may not increase the number of shares of preferred stock (of whatever
series) authorized for issuance, or declare or pay any dividends on shares of
Common Stock or other junior shares. As discussed under "Redemption Rights"

Stock (determined on a fully diluted basis) will hold less than a majority of
the outstanding shares of Common Stock or other equity interest of the
Company, person or entity resulting from such transaction, or any parent of
such entity.

Series D Preferred Stock

There are 25,000 shares of Series D Cumulative Convertible Preferred Stock
of KMC Holdings ("Series D Preferred Stock") authorized, none of which are
outstanding at December 31, 1998. There were 25,000 of such shares issued to
Nassau in November 1997, generating aggregate gross proceeds of $2.5 million.
In January 1998, Nassau exercised its conversion rights and converted all of
its shares of Series D Preferred Stock into an equal number of shares of
Series C Preferred Stock.

Common Stock

Holders of Common Stock of the Company are entitled to one vote for each
share held on all matters submitted to a vote of stockholders, except with
respect to the election of Directors. Except as otherwise required by law,
actions at the Company's stockholders meetings (held at least annually),
require the affirmative vote of a majority of the shares represented at the
meeting, a quorum being present. Holders of Common Stock are entitled, subject
to the preferences of preferred stock, to receive such dividends, if any, as
may be declared by the Board of Directors out of funds legally available
therefor. The Senior Discount Note Indenture and the Company's other
indebtedness restrict the ability of the Company to pay dividends on its
Common Stock. Without the prior consent of two-thirds of the shares of Series
A Preferred Stock and two-thirds of the shares of Series C Preferred Stock,
the Company may not declare or pay any dividends on its Common Stock. Except
as discussed under "Redemption Rights" below, the holders of Common Stock have
no preemptive, redemption or conversion rights.

Pursuant to provisions contained in the Company's Certificate of
Incorporation and an Amended and Restated Stockholders Agreement dated as of
October 31, 1997, among the Company, Kamine, Nassau, AT&T Credit Corporation
("AT&T Credit"), GECC, and CoreStates (the "Stockholders' Agreement"), until
Kamine and Nassau cease to own Common Stock or preferred stock convertible
into Common Stock representing at least five percent of the outstanding shares
of Common Stock, assuming all convertible securities are converted, Kamine and
Nassau have special rights entitling each to elect three Directors. A Director
elected by Kamine's shares or Nassau's shares may not be removed except with
the affirmative vote of a majority of the applicable shares of capital stock.
If Kamine or Nassau transfer their shares of capital stock, the number of
Directors their shares are entitled to elect decreases. The number of
Directors which Kamine is entitled to elect would be reduced to two if the
number of shares owned by him were to fall below two-thirds of the number of
shares of the Company initially issued to him, and to one if the number of
shares owned by him were to fall below one-third of the number of shares
initially issued to him. If his ownership were to fall below 5% of the number
of shares initially issued to him, Kamine would no longer be entitled to elect
any Directors pursuant to such provisions. Comparable reductions would be made
to the number of Directors which Nassau is entitled to elect if its ownership
were to fall below the specified percentages. Directors other than those
elected by vote of Kamine's shares or Nassau's shares are elected by holders
of Common Stock and holders of preferred stock that are entitled to vote in
the election of Directors. If a default relating to payment occurs under the
Senior Secured Credit Facility and continues uncured for 90 days, the holders
of Series C Preferred Stock (currently Nassau, GECC and CoreStates) are
entitled to elect two additional Directors, who will serve until the default
is cured.

Redemption Rights

Pursuant to the Stockholders' Agreement, each of Nassau, AT&T Credit, GECC
and CoreStates has a "put right" entitling it to have the Company repurchase
its preferred and common shares for the fair market value of

F-28

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

such shares if no Liquidity Event (defined as (i) an initial public offering
with gross proceeds of at least $40 million, (ii) the sale of substantially
all of the stock or assets of the Company or (iii) the merger or consolidation
of the Company with one or more other corporations) has taken place by the
later of (x) October 22, 2003 or (y) 90 days after the final maturity date of
the Senior Discount Notes (issued in January 1998, with a stated maturity date
of February 15, 2008). CoreStates, GECC and AT&T Credit may not exercise such
put rights unless Nassau has exercised its put right. The Senior Discount Note
Indenture limits the Company's ability to repurchase such shares. All of the
shares of preferred and common stock subject to such "put right" are presented
as redeemable equity in the accompanying balance sheets.

The redeemable preferred stock, redeemable common stock and redeemable
common stock warrants (described below) are being accreted to their fair
market values from their respective issuance dates to their earliest potential
redemption date (October 22, 2003). At December 31, 1998, the aggregate
redemption value of the redeemable equity was approximately $152 million,
reflecting per share redemption amounts of $630 for the Series A Preferred
Stock, $248 for the Series C Preferred Stock and $130 for the redeemable
common stock and redeemable common stock warrants. Accordingly, $8,246,000 and
$17,861,000 of accretion have been charged to additional paid-in-capital in
1997 and 1998, respectively.

Warrants

In connection with KMC Telecom's 1996 Loan and Security Agreement, warrants
representing a 2.5% ownership interest in the fully diluted common voting
capital stock of KMC Telecom, including anti-dilution protection, were granted
to the lenders. These warrants, at an exercise price of $.01 per share, were
issued on January 21, 1997, concurrent with the initial borrowing under the
AT&T Facility, at which date the fair value of such warrants was determined to
be $1.5 million, which was reflected as a charge to deferred financing costs
and credited to redeemable equity in January 1997. On September 22, 1997, such
warrants were exercised, and an aggregate of 28,000 shares of Class A Common
Stock of KMC Telecom were issued to the warrant holders. These shares were
subsequently exchanged for an equal number of shares of Common Stock of KMC
Holdings.

In connection with the AT&T Facility, warrants to purchase 10,000 shares of
Common Stock were issued to GECC in 1997. These warrants, at an exercise price
of $.01 per share, are exercisable from issuance through January 21, 2005. The
fair value of such warrants was determined to be $525,000, which was reflected
as a charge to deferred financing costs and credited to redeemable equity.
Pursuant to the Stockholders' Agreement, GECC may put the shares of Common
Stock issuable upon the exercise of such warrants back to the Company. These
warrants have been presented as redeemable common stock warrants in the
accompanying balance sheet at December 31, 1998.

In connection with the sale of Senior Discount Notes in January 1998, the
Company issued warrants to purchase an aggregate of 100,385 shares of Common
Stock at an exercise price of $.01 per share. The net proceeds of $10,446,000
represented the fair value of the warrants at the date of issuance. The
warrants are exercisable through January 2008.

Options

Prior to the establishment of the present holding company structure, during
1996 and 1997, KMC Telecom granted options to purchase shares of its common
stock, par value $.01 per share ("KMC Telecom Common Stock"), to employees
pursuant to the KMC Telecom Stock Option Plan.

In order to reflect the establishment of the holding company structure, on
June 26, 1998, the Board of Directors adopted a new stock option plan, the KMC
Holdings Stock Option Plan (the "1998 Plan"), which authorizes the grant of
options to purchase Common Stock of the Company. The 1998 Plan was approved by
the

F-29

KMC TELECOM HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

stockholders, effective July 15, 1998. In September 1998, the Company replaced
the options to purchase KMC Telecom Common Stock previously granted under the
KMC Telecom Stock Option Plan with options to purchase Common Stock of the
Company granted under the 1998 Plan and granted options to additional
employees of the Company under the 1998 Plan.

The 1998 Plan, which is administered by the Compensation Committee of the
Board of Directors of KMC Holdings, provides for various grants to key
employees, directors, affiliated members or other persons having a unique
relationship with the Company excluding Kamine and any person employed by
Nassau Capital or any Nassau affiliate. Grants may include, without
limitation, incentive stock options, non-qualified stock options, stock
appreciation rights, dividend equivalent rights, restricted stocks, purchase
stocks, performance shares and performance units. The Compensation Committee
has the power and authority to designate recipients of the options and to
determine the terms, conditions, and limitations of the options.

Under the 1998 Plan, options to purchase 262,750 shares of Common Stock of
KMC Holdings are available for grant, all of which were allocated to the Plan
as of December 31, 1998. No individual may receive options for more than
75,000 shares. The exercise price of all incentive stock options granted under
the 1998 Plan must be at least equal to the fair market value of the shares on
the date of grant. The exercise price of all non-qualified stock options
granted under the 1998 Plan must be at least 50% of the fair market value of
the shares on the date of grant.

Options granted pursuant to the 1998 Plan will have terms not to exceed 10
years and become exercisable over a vesting period as specified in such
options. The 1998 Plan will terminate no later than 2008. Options granted
under the 1998 Plan are nontransferable, other than by will or by the laws of
descent and distribution, and may be exercised during the optionee's lifetime,
only by the optionee.

The 1998 Plan provides for an adjustment of the number of shares
exercisable in the event of a merger, consolidation, recapitalization, change
of control, stock split, stock dividend, combination of shares or other
similar changes, exchange or reclassification of the Common Stock at the
discretion of the Compensation Committee. Pursuant to the agreements adopted
under the 1998 Plan, the greater of 25% of the shares granted or fifty percent
of all unvested options granted become fully vested upon a change-in-control
of the Company, as defined. Under certain circumstances, such percentages may
increase.

The holders of options to acquire shares of Common Stock of KMC Holdings
are required to enter into agreements with KMC Holdings which place certain
restrictions upon their ability to sell or otherwise transfer such shares. In
the event of termination of employment of the option holder by the Company or
the affiliates, the Company can repurchase all of the shares or options held
by such individuals, generally for an amount equal to the fair value of such
shares or the excess of the fair value of such options over their exercise
price.

</TABLE>

The weighted-average exercise price of options exercisable at December 31,
1997 and 1998 is $50 and $22, respectively, and the weighted-average fair
value of options granted during 1996, 1997 and 1998 were $30, $49 and $114 per
share, respectively. Exercise prices for options outstanding as of December
31, 1998 ranged from $20 to $40. The weighted-average remaining contractual
life of those options is 9.7 years.

During the year ended December 31, 1998, non-qualified options to purchase
an aggregate of 262,500 shares were granted at exercise prices of $20 (157,500
options), $30 (52,500 options) and $40 (52,500 options). The options granted
during 1998 are comprised of 230,500 options granted to employees and 32,000
options granted to individuals employed by certain affiliates of the Company.
All such options have 10 year terms. The $20 options become exercisable over a
three year period in six month intervals commencing six months after the grant
date in increments of 26,250 options each. The $30 options become exercisable
in two increments of 26,250 options each, forty-two and forty-eight months
after the grant date. The $40 options become exercisable in two increments of
26,250 options each, fifty-four and sixty months after the grant date. For
purposes of vesting, options granted in 1998 under the 1998 Plan to replace
options granted in 1997 and 1996 under the KMC Telecom Stock Option Plan are
deemed to have been granted on the date of grant of the options which they
replace.

As a result of certain anti-dilution provisions governing the conversion of
shares of Class C Common Stock into shares of Class A Common Stock, KMC
Telecom was required to account for the KMC Telecom Stock Option Plan as a
variable stock option plan. Additionally, as a result of restrictions upon the
holders of options granted under the 1998 Plan, including their ability to
sell or otherwise transfer the related shares, the 1998 Plan is required to be
accounted for as a variable stock option plan. Generally accepted accounting
principles for variable stock option plans require the recognition of a non-
cash compensation charge for these options (amortized over the vesting period
of the employee options and recognized in full as of the grant date for the
non-employee options). Such charge is determined by the difference between the
fair value of the common stock underlying the options and the option price as
of the end of each period. Accordingly, compensation expense will be charged
or credited periodically through the date of exercise or cancellation of such
stock options, based on changes in the value of the Company's stock as well as
the vesting schedule of such options. These compensation charges or credits
are non-cash in nature, but could have a material effect on the Company's
future reported results of operations.

F-31
<PAGE>

KMC TELECOM HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

The Company, upon cancellation of the outstanding options under the KMC
Telecom Stock Option Plan, reversed all compensation expense previously
recorded with respect to such options. Additionally, to the extent the fair
value of the Common Stock of the Company exceeded the exercise price of the
options granted under the 1998 Plan, the Company recognized compensation
expense related to such options over their vesting period.

Based on the estimated fair value of the Common Stock of KMC Telecom at
December 31, 1996 and 1997, and KMC Holdings at December 31, 1998, cumulative
deferred compensation obligations of $1,283,000, $15,579,000 and $27,906,000,
respectively, have been established. The Company has recognized compensation
expense aggregating $240,000, $13,870,000 and $7,080,000 for the years ended
December 31, 1996, 1997 and 1998, respectively. The 1998 stock option
compensation expense of $7,080,000 reflects charges of $7,236,000 under the
KMC Telecom Stock Option Plan through its termination in September 1998 and
charges of $21,190,000 related to the 1998 Plan, partially offset by a credit
as a result of the September 1998 cancellation of the KMC Telecom stock
options, reflecting the reversal of $21,346,000 of cumulative compensation
previously recognized for options granted under the KMC Telecom Stock Option
Plan.

In accordance with the provisions of Statement 123, the Company applies APB
25 and related interpretations in accounting for its stock option plan. If the
Company had elected to recognize compensation expense based on the fair value
of the options granted at grant date as prescribed by Statement 123, net loss
and net loss per common share would have been the following:

The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted average
assumptions:

Expected life of options....................... 7 years 7 years 7 years
</TABLE>

The expected stock price volatility factors were determined based on an
average of such factors as disclosed in the financial statements of peer
companies. The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value
estimate, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options.

8. Income Taxes

As of December 31, 1998, the Company and its subsidiaries had consolidated
net operating loss carryforwards for United States income tax purposes
("NOLs") of approximately $59 million which expire through 2013. Under Section
382 of the Internal Revenue Code of 1986, as amended, if the Company undergoes
an "ownership change," its ability to use its preownership change NOLs (NOLs
accrued through the date of the ownership change) would generally be limited
annually to an amount equal to the product of (i) the long-term tax-exempt
rate for ownership changes prescribed monthly by the Treasury Department and
(ii) the value of the Company's equity immediately before the ownership
change, excluding certain capital contributions. Any allowable portion of the
preownership change NOLs that is not used in a particular taxable year
following the ownership change could be carried forward to subsequent taxable
years until the NOLs expire, usually 15 years after they are generated. As a
result of the cumulative effect of issuances of preferred and common stock
through September 22, 1997, KMC Telecom has undergone an ownership change.

For financial reporting purposes, the Company has an aggregate of
approximately $38 million and $109 million of loss carryforwards and net
temporary differences at December 31, 1997 and 1998, respectively. At existing
federal and state tax rates, the future benefit of these items approximates
$15 million at December 31, 1997 and $42 million at December 31, 1998.
Valuation allowances have been established equal to the entire net tax benefit
associated with all carryforwards and temporary differences at both December
31, 1997 and 1998 as their realization is uncertain.

The composition of expected future tax benefits at December 31, 1997 and
1998 is as follows:

for the years ended December 31, 1996, 1997 and 1998, respectively.

Litigation

By letter dated August 29, 1997, KMC Telecom notified I-Net, Inc. ("I-NET")
that KMC Telecom considered I-NET to be in default under a Master
Telecommunications System Rollout Agreement, dated as of October 1, 1996 (the
"I-Net Agreement"), as a result of I-NET's failure to provide design plans and
specifications for several systems for which it had agreed to provide such
plans and specifications, to properly supervise construction of the systems or
to provide personnel with the necessary expertise to manage the projects. On
February 12, 1998, the Company received a demand for arbitration from Wang
Laboratories, Inc. ("Wang"), the successor to I-NET. The demand seeks at least
$4.1 million. The Company believes that it has meritorious defenses to Wang's
claims and has asserted counterclaims seeking in excess of $2.5 million as a
result of I-NET's defaults under the I-NET Agreement.

The arbitration proceedings are currently underway. The Company believes
that resolution of this matter will not have a material adverse impact on its
financial condition. No assurance can be given, however, as to the ultimate
resolution of this matter.

There are a number of lawsuits and regulatory proceedings related to the
Telecommunications Act of 1996, decisions of the Federal Communications
Commission related thereto and rules and regulations issued thereunder which
may affect the rights, obligations and businesses of incumbent local exchange
carriers, competitive local exchange carriers and other participants in the
telecommunications industry in general, including the Company.

Purchase Commitments

As of December 31, 1998, the Company has outstanding commitments
aggregating approximately $30.6 million related to purchases of
telecommunications equipment and fiber optic cable and its obligations under
its agreements with certain suppliers and service providers.

Employment Agreements

The Company has entered into employment agreements with certain of its
executives. In addition to a base salary, these agreements also provide for
certain incentive compensation payments, based upon completion of

F-34
<PAGE>

KMC TELECOM HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

construction and attainment of specified revenues for additional networks. The
Company has also agreed to make similar incentive compensation payments to
certain other key employees.

10. Acquisition

On July 11, 1997, KMC Telecom acquired a network in Melbourne, Florida for
a purchase price of $2 million in cash. The acquisition was accounted for
under the purchase method and the purchase price approximated the fair value
of the fixed assets acquired. Assuming the Melbourne Network had been acquired
as of January 1, 1997, the Company's pro forma consolidated revenue and net
loss for the year ended December 31, 1997 would have been $3,655,000 and
$33,212,000, respectively.

11. Related Party Transactions

During 1996, KMC Telecom had borrowings from Kamine. The proceeds of such
loans were used to fund the construction of the network in Huntsville,
Alabama, and to fund operating cash flow requirements. These loans were
payable on demand and, through April 30, 1996, bore interest at the prime
rate. Interest expense charged by Kamine under these loans amounted to
$120,000 for the year ended December 31, 1996. Effective May 1, 1996, Kamine
elected not to charge interest on these loans. However, for financial
reporting purposes, $180,000 of interest expense was imputed on these loans
for the period from May 1, 1996 to their repayment on November 12, 1996, and a
corresponding credit has been recorded to additional paid-in capital.

The Company and certain affiliated companies owned by Kamine share certain
administrative services. The entity which bears the cost of the service is
reimbursed by the other for the other's proportionate share of such expenses.
The Company reimbursed Kamine-affiliated companies for these shared services
an aggregate of approximately $488,000, $281,000 and $136,000 of expense for
the years ended December 31, 1996, 1997 and 1998, respectively.

From May 1, 1996 through January 29, 1998, an affiliate of the Company was
paid a fee at an annual rate of $266,000 as reimbursement for the services of
Kamine as Chairman of the Board of the Company. The amount of this fee was
reduced to $100,000 per annum as of January 29, 1998 and it was terminated
effective December 31, 1998. The fees paid for these services are included in
the shared services payment described in the immediately preceding paragraph.
Effective January 1, 1999, Kamine became an employee of the Company and he is
currently paid a salary at the rate of $450,000 per annum for his services as
Chairman of the Board.

The Company leases its headquarters office through January 2007 from an
entity controlled by Kamine. The lease provides for a base annual rental cost
of approximately $217,000, adjusted periodically for changes in the consumer
price index, plus operating expenses. Rent expense recognized under this lease
for the years ended December 31, 1996, 1997 and 1998 was $97,000, $207,000 and
$217,000, respectively.

As of December 31, 1998, the Company has made loans aggregating $760,000,
to certain of its executives. Such loans bear interest at a rate of 6% per
annum and are included in other assets.

The Company has reached an agreement in principle with KMC Services LLC, a
limited liability company wholly-owned by Kamine ("KMC Services"), pursuant to
which KMC Services will offer to the Company financial and energy services
which are related to the Company's business. KMC Services may also offer its
services to third parties in jurisdictions in which the Company is not
offering telecommunications services; provided that such third parties are not
competitors of the Company. Initially, KMC Services will offer a leasing
program for equipment physically installed at a customer's premises ("CPE
Equipment") for the Company to integrate into its ClearStar SM Advantage
program, whereby the Company will be able to offer CPE Equipment for lease or
sale to its customers. The equipment will be owned by KMC Services, and the
Company will have no liability for the cost of the equipment, the financing
related to it or the obligation for any lease charges. Any

F-35

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

such sale or lease will be between the Company's customer and KMC Services.
The specific terms and conditions of the agreement between KMC Services LLP
and the Company are currently being negotiated by the parties.

Effective January 1, 1999, the Company is entitled to utilize a Citation
III business jet, chartered by Bedminster Aviation, LLC, a limited liability
company wholly-owned by Kamine, for a fixed price per hour of flight time. The
Company has agreed to use its best efforts to utilize the Citation III fifty
hours per quarter during 1999. The Company is under no obligation to do so and
has not guaranteed any financial arrangements with respect to the aircraft or
to Bedminster Aviation, LLC.

Pursuant to an agreement among the Company, Kamine and Nassau, for 1997 and
1998 Nassau received $100,000 as a financial advisory fee and as compensation
for the Nassau designees who served on the Board of Directors of the Company.
Nassau will be paid $450,000 as a financial advisory fee for 1999.

Options and warrants to purchase an aggregate of 242,768 and 372,885 shares
of common stock were outstanding as of December 31, 1997 and 1998,
respectively, but a computation of diluted net loss per common share has not
been presented, as the effect of such securities would be anti-dilutive.

of $1,283,000, $15,579,000 and $27,906,000 have been established in 1996, 1997
and 1998, respectively, with offsetting credits to additional paid-in capital.
Noncash compensation expense of $44,000, $9,014,000 and $23,758,000 in 1996,
1997 and 1998, respectively, was recognized in connection with such options.
In connection with options granted to individuals employed by certain

noncash compensation expense of $196,000, $4,856,000 and $4,668,000,
respectively. In addition, during 1998 the Company cancelled all of the then
outstanding options granted under the KMC Telecom Stock Option Plan, resulting
in the reversal of previously recognized compensation expense of $21.3
million.

14. Financial Instruments

The following methods and assumptions were used to estimate the fair value
of each class of financial instruments.

Cash and Cash Equivalents

The carrying amounts approximate fair value because of the short-term
maturity of the instruments.

Investments Held for Future Capital Expenditures

The carrying amounts and fair value are reported at amortized cost since
these securities are to be held to maturity.

Long-Term Debt

The carrying amount of floating-rate long-term debt approximates its fair
value. The fair value of the Company's fixed-rate long-term debt is estimated
using discounted cash flows at the Company's incremental borrowing rates.

Redeemable Equity

The fair values of the Company's redeemable equity instruments are
estimated to be the amounts at which the holders may require the Company to
redeem such securities, adjusted using discounted cash flows.

The carrying amounts and estimated fair values of the Company's financial
instruments are as follows (in millions):

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash investments and
accounts receivable. The Company places its cash investments with major
financial institutions. With respect to accounts receivable, the Company
performs ongoing credit evaluations of its customers' financial conditions and
generally does not require collateral. No individual customer accounted for
more than 10% of revenue, excluding reciprocal compensation revenue, as
described below, for the years ended December 31, 1997 and 1998.

The Company maintains interconnection agreements with incumbent local
exchange carriers ("ILECs") in each state in which it operates. Among other
things, these contracts govern the reciprocal amounts to be billed by
competitive carriers for terminating local traffic of Internet service
providers ("ISPs") in each state. The Regional Bell Operating Companies have
advised competitive local exchange carriers, such as the Company, that they do
not consider calls in the same local calling area which are placed by their
customers to competitive local exchange carrier customers which are Internet
service providers to be local calls under the interconnection agreements. The
Regional Bell Operating Companies claim that these calls are exchange access
calls, which the Federal Communications Commission exempted from payment of
access charges. The Regional Bell Operating Companies claim that, as a result,
they do not owe any compensation to competitive local exchange carriers for
transporting and terminating these calls. The Regional Bell Operating
Companies have threatened to withhold, and in many cases have withheld,
reciprocal compensation to competitive local exchange carriers for the
transport and termination of these calls. During 1998, the Company recognized
revenue from these ILECs of approximately $2.9 million, or 12.9% of 1998
revenue, for these services. Payments of approximately $135,000 were received
from the ILECs during 1998.

Management believes reciprocal compensation for Internet traffic to be an
industry-wide matter that will ultimately be resolved on a state-by-state
basis. To date, twenty-nine state commissions have ruled on the issue and
found that ILECs must pay compensation to competitive carriers for local calls
to ISPs located on competitive carriers' networks. A number of other state
commissions currently have proceedings pending to consider this matter. The
Federal Communications Commission has concluded that calls to ISPs are
interstate calls and therefore exempt from local termination charges. However,
the Commission also stated that existing interconnection agreements providing
for such termination charges must be honored by the ILECs.

The Company accounts for reciprocal compensation with the ILECs, including
the activity associated with the disputed ISP traffic, as local traffic
pursuant to the terms of its interconnection agreements. Accordingly, revenue
is recognized in the period that the traffic is terminated. The circumstances
surrounding the disputes are considered by management periodically in
determining whether reserves against unpaid balances are warranted. As of
December 31, 1998, no reserves have been considered necessary by management.

15. Subsequent Events

Lucent Loan and Security Agreement

KMC Telecom III entered into a Loan and Security Agreement (the "Lucent
Facility") dated February 4, 1999 with Lucent Technologies Inc. ("Lucent")
which provides for borrowings to be used to fund the acquisition of certain
telecommunications equipment and related expenses. The Lucent Facility
provides for an aggregate commitment of up to $600 million, of which $125
million is immediately available to purchase Lucent products and an additional
$125 million will become available upon KMC Telecom III's receipt of an
additional $35 million of funded equity or qualified intercompany loans, as
defined in the agreement. Further, up to an additional $350 million will be
available upon (a) additional lenders participating in the Lucent Facility and
making commitments to make loans so that Lucent's aggregate commitment does
not exceed $250 million and (b) the

F-38
<PAGE>

KMC TELECOM HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Company satisfying certain other requirements, the most significant of which
is KMC Holdings raising and contributing at least $300 million in high yield
debt or equity (other than disqualified stock) to KMC Telecom III. The Lucent
Facility places certain restrictions upon KMC Telecom III's ability to
purchase non-Lucent equipment with proceeds from such facility.

Interest on borrowings under the Lucent Facility is charged, at the option
of KMC Telecom III, at a floating rate of LIBOR plus the "Applicable LIBOR
Margin", or at an alternative base rate plus the "Applicable Base Rate Margin"
(as defined). Such margins will be increased by 0.25% until KMC Telecom III
and its subsidiaries have completed systems in fourteen markets. If KMC
Telecom III defaults on any payment due under the Lucent Facility, the
interest rate will increase by four percentage points. If any other event or
default shall occur, the interest rate will be increased by two percentage
points. Interest on each LIBOR loan is payable on each LIBOR interest payment
date in arrears and interest on each base rate loan is payable quarterly in
arrears. KMC Telecom III must pay an annual commitment fee on the unused
portion of the Lucent Facility of 1.25%.

Loans borrowed under the Lucent Facility amortize in amounts based upon the
following percentages of the aggregate amount of the loans drawn under the
Lucent Facility:

<TABLE>
<CAPTION>
Payment Dates Amortization
------------- ----------------
<S> <C>
May 1, 2002--February 1, 2003............................... 2.5% per quarter
May 1, 2003--February 1, 2006............................... 5.0% per quarter
May 1, 2006--February 1, 2007............................... 7.5% per quarter
</TABLE>

KMC Holdings has unconditionally guaranteed the repayment of up to $250.0
million under the Lucent Facility when such repayment is due, whether at
maturity, upon acceleration, or otherwise. KMC Telecom III Holdings, Inc.,
which owns the shares of KMC Telecom III and is wholly-owned by KMC Holdings,
has pledged the shares of KMC Telecom III to Lucent to collateralize its
obligations under the guaranty. In addition, KMC Telecom III has pledged all
of its assets to Lucent.

KMC TELECOM HOLDINGS, INC.
(PARENT COMPANY)

NOTES TO CONDENSED FINANCIAL STATEMENTS
December 31, 1998

1. Basis of Presentation

In the parent company only financial statements, KMC Telecom Holdings,
Inc."s (the "Company") investment in subsidiaries is stated at cost less
equity in losses of subsidiaries since date of formation. These parent company
financial statements should be read in conjunction with the Company's
consolidated financial statements. The Company's operating subsidiaries are
KMC Telecom Inc. ("KMC Telecom"), KMC Telecom II, Inc. ("KMC Telecom II"), KMC
Telecom III, Inc. ("KMC Telecom III") and KMC Telecom of Virginia, Inc.

On September 22, 1997, the stockholders of KMC Telecom exchanged all of
their KMC Telecom common and preferred stock for equal numbers of shares of
common and preferred stock of the Company.

Pursuant to a management agreement among the Company and its subsidiaries,
the Company provides management and other services and incurs certain
operating expenses on behalf of its subsidiaries. Such costs are allocated to
the subsidiaries by the Company and reimbursed on a current basis. At December
31, 1998, an aggregate of $20.9 million was due from the subsidiaries for such
costs and is included in the accompanying condensed balance sheet at December
31, 1998 as a current receivable. Such reimbursements are permitted under the
debt agreements of the Company's subsidiaries.

2. Guarantee

On December 22, 1998, KMC Telecom, KMC Telecom II and KMC Telecom of
Virginia, Inc. (the "Borrowers"), entered into a Loan and Security Agreement
(the "Senior Secured Credit Facility") with AT&T Commercial Finance
Corporation, First Union National Bank, General Electric Capital Corporation
and Canadian Imperial Bank of Commerce (the "Lenders").

The Company has unconditionally guaranteed the repayment of the Senior
Secured Credit Facility when such repayment is due, whether at maturity, upon
acceleration, or otherwise. The Company has agreed to pay all amounts
outstanding under the Senior Secured Credit Facility, on demand, upon the
occurrence and during the continuation of any event of default (as defined
therein). The Company has pledged the shares of each of the Borrowers to the
Lenders to collateralize its obligations under the guaranty. In addition, the
Borrowers have pledged all of their assets to the Lenders. Accordingly, if
there were an event of default under the Senior Secured Credit Facility, the
lenders thereunder would be entitled to payment in full and could foreclose on
the assets of the Borrowers, and the holders of the Senior Discount Notes
would have no right to share in such assets. At December 31, 1998, an
aggregate of $41.4 million was outstanding under this facility.

Additionally, the Senior Secured Credit Facility restricts the ability of
the Borrowers to pay dividends to, or to pay principal or interest on loans
from, the Company. Such restrictions could adversely affect the Company's
liquidity and ability to meet its cash requirements, including its ability to
repay the Senior Discount Notes.

At December 31, 1998, an aggregate of $265.7 million has been loaned by the
Company to the Borrowers to be used for the construction and expansion of
fiber optic telecommunications networks and for working capital and general
corporate purposes.

3. Senior Discount Notes

On January 29, 1998, the Company sold 460,800 units, each consisting of a
12 1/2% senior discount note with a principal amount at maturity of $1,000 due
2008 pursuant to the Senior Discount Note Indenture between the Company and
the Chase Manhattan Bank, as trustee (the "Senior Discount Notes") and one
warrant to purchase .21785 shares of Common Stock of the Company at an
exercise price of $.01 per share. The gross and net proceeds of the offering
were approximately $250.0 million and $236.4 million, respectively. A

S-5
<PAGE>

KMC TELECOM HOLDINGS, INC.
(PARENT COMPANY)

NOTES TO CONDENSED FINANCIAL STATEMENTS--(Continued)
December 31, 1998

substantial portion of the net proceeds of the offering have been loaned by
the Company to its subsidiaries. On August 11, 1998, the Company consummated
an offer to exchange the notes issued on January 29, 1998 for $460.8 million
aggregate principal amount at maturity of notes that had been registered under
the Securities Act of 1933 (as used below and elsewhere herein, "Senior
Discount Notes" includes the original notes and the exchange notes).

The Senior Discount Notes are unsecured, unsubordinated obligations of the
Company and mature on February 15, 2008. The Senior Discount Notes will fully
accrete to face value on February 15, 2003. From and after February 15, 2003,
the Senior Discount Notes will bear interest, which will be payable in cash,
at the rate of 12.5% per annum on February 15 and August 15 of each year,
commencing August 15, 2003. The Company is accreting the initial carrying
value of the Senior Discount Notes to their aggregate face value over the term
of the debt at its effective interest rate of 13.7%.

The indebtedness evidenced by the Senior Discount Notes ranks pari passu in
right of payment with all existing and future unsubordinated, unsecured
indebtedness of the Company and senior in right of payment to all existing and
future subordinated indebtedness of the Company. However, the Company is a
holding company and the Senior Discount Notes are, therefore, effectively
subordinated to all existing and future liabilities (including trade payables)
of its subsidiaries.

The Senior Discount Notes restrict, among other things, the ability of the
Company to incur additional indebtedness, create liens, engage in sale-
leaseback transactions, pay dividends or make distributions in respect of
capital stock, make investments or certain other restricted payments, sell
assets of the Company, redeem capital stock, issue or sell stock of restricted
subsidiaries, enter into transactions with stockholders or affiliates or
effect a consolidation or merger.

4. Redeemable Equity

Pursuant to provisions contained in the Company's Certificate of
Incorporation and an Amended and Restated Stockholders' Agreement dated as of
October 31, 1997, among the Company, Harold N. Kamine, Nassau Capital Partners
L.P. and NAS Partners I L.L.C. (collectively referred to as "Nassau"), AT&T
Credit Corporation ("AT&T Credit"). General Electric Capital Corporation
("GECC"), and CoreStates Bank, N.A. ("CoreStates"), (the "Stockholders'
Agreement"), each of Nassau, CoreStates, AT&T Credit and GECC has a "put
right" entitling it to have the Company repurchase its preferred and common
shares for the fair market value of such shares if no Liquidity Event (defined
as (i) an initial public offering with gross proceeds of at least $40.0
million, (ii) the sale of substantially all of the stock or assets of the
Company or (iii) the merger or consolidation of the Company with one or more
other corporations) has taken place by the later of (x) October 22, 2003 or
(y) 90 days after the final maturity date of the Senior Discount Notes (issued
in January 1998, with a stated maturity date of February 15, 2008).
CoreStates, GECC and AT&T Credit may not exercise such put rights unless
Nassau has exercised its put right. The restrictive covenants of the Senior
Discount Notes limit the Company's ability to repurchase such shares. All of
the shares of preferred and common stock subject to such "put right" are
presented as redeemable equity in the accompanying condensed balance sheets at
December 31, 1997 and 1998.

The redeemable preferred stock, redeemable common stock and redeemable
common stock warrants (described below) are being accreted up to their fair
market values from their respective issuance dates to their earliest potential
redemption date (October 22, 2003). At December 31, 1998, the aggregate
redemption value of the redeemable equity was approximately $152 million,
reflecting per share redemption amounts of $630 for the

S-6
<PAGE>

KMC TELECOM HOLDINGS, INC.
(PARENT COMPANY)

NOTES TO CONDENSED FINANCIAL STATEMENTS--(Continued)
December 31, 1998

Series A Preferred Stock, $248 for the Series C Preferred Stock and $130 for
the redeemable common stock and redeemable common stock warrants.

Warrants to purchase 10,000 shares of Common Stock were issued to GECC in
1997. These warrants, at an exercise price of $.01 per share, are exercisable
from issuance through January 2005. Pursuant to the Stockholders' Agreement,
GECC may put the shares of Common Stock issuable upon the exercise of such
warrants back to the Company. These warrants have been presented as redeemable
common stock warrants in the accompanying condensed balance sheets at December
31, 1997 and 1998.

5. Contingencies

By letter dated August 29, 1997, KMC Telecom notified I-NET, Inc. ("I-NET")
that KMC Telecom considered I-NET to be in default under a Master
Telecommunications Systems Rollout Agreement dated as of October 1, 1996 (the
"I-NET Agreement"), as a result of I-NET's failure to provide design plans and
specifications for several systems for which it had agreed to provide such
plans and specifications, to properly supervise construction of the systems or
to provide personnel with the necessary expertise to manage the projects. On
February 12, 1998, the Company received a demand for arbitration from Wang
Laboratories, Inc. ("Wang") the successor to I-NET. The demand seeks at least
$4.1 million. The Company believes that it has meritorious defenses to Wang's
claims and has asserted counterclaims seeking in excess of $2.5 million as a
result of I-NET's defaults under the I-NET Agreement. The arbitration
proceedings are currently underway. The Company believes that resolution of
this matter will not have a material adverse impact on its financial
condition. No assurance can be given, however, as to the ultimate resolution
of this matter.

6. Subsequent Events

Lucent Loan and Security Agreement

KMC Telecom III entered into a Loan and Security Agreement (the "Lucent
Facility") dated February 4, 1999 with Lucent Technologies, Inc. ("Lucent")
which provided for borrowings up to $600 million (of which $125 million is
immediately available) to be used to fund the acquisition of certain
telecommunications equipment and related expenses.

The Company has unconditionally guaranteed the repayment of up to $250
million under the Lucent Facility when such repayment is due, whether at
maturity, upon acceleration, or otherwise. KMC Telecom III Holdings, Inc.,
which owns the shares of KMC Telecom III and is wholly-owned by the Company,
has pledged the shares of KMC Telecom III to Lucent to collateralize its
obligations under the guaranty. In addition, KMC Telecom III has pledged all
of its assets to Lucent. Accordingly, if there were an event of default under
the Lucent Facility, Lucent thereunder would be entitled to payment in full
and could foreclose on the assets of the Borrower and the holders of the
Senior Discount Notes would have no right to share in such assets.

Additionally, the Lucent Facility restricts the ability of KMC Telecom III
to pay dividends to, or to pay principal or interest on loans from, the
Company. Such restrictions could adversely affect the Company's liquidity and
ability to meet its cash requirements, including its ability to repay the
Senior Discount Notes.

Series E Preferred Stock

On February 4, 1999, the Company issued 25,000 shares of Series E Senior
Redeemable, Exchangeable, PIK Preferred Stock (the "Series E Preferred Stock")
to Newcourt Commercial Finance Corporation ("Newcourt Finance"), generating
aggregate gross proceeds of $22.9 million. The Series E Preferred Stock has a
liquidation preference of $1,000 per share and an annual dividend equal to
14.5% of the liquidation preference, payable quarterly. On or before January
15, 2004, the Company may pay dividends in cash or in additional fully paid
and nonassessable shares of Series E Preferred Stock. After January 15, 2004,
dividends must be paid in cash, subject to certain conditions. Unpaid
dividends accrue at the dividend rate of the Series E Preferred Stock,
compounded quarterly.

The Series E Preferred Stock is not convertible. The Company may, at the
sole option of the Board of Directors (out of funds legally available),
exchange all, but not less than all, of the Series E Preferred Stock then
outstanding, for a new series of subordinated debentures (the "Exchange
Debentures") issued pursuant to an exchange debenture indenture.

(ii) February 4, 2001, the Warrant Agent is authorized to issue the Springing
Warrants to the Eligible Holders (as defined in the warrant agreement) of the
Series E and Series F Preferred Stock. In the event the Company has redeemed
all outstanding shares of Series F Preferred Stock prior to the Springing
Warrant Date, the Springing Warrants will not be issued and the Warrant Agent
will return the certificates to the Company. To the extent the Company
exercises its option to exchange all of the Series F Preferred Stock for
Exchange Debentures prior to the Springing Warrant Date, the Springing
Warrants will not become issuable. Therefore, as the future issuance of the
Springing Warrants is entirely within control of the Company and the
likelihood of their issuance is deemed to be remote, no value has been
ascribed to the Springing Warrants.

INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Article Seventh of the Certificate of Incorporation, as amended, provides
that a director of the corporation shall not be personally liable to the
corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director except for liability (i) for any breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law, or (iv) for any transaction from which the director derived
any improper personal benefit. No amendment or repeal of this provision shall
apply to or have any effect on the liability or alleged liability of any
director for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal. Article VI, Section 5 of the By-
Laws provides that the Corporation shall indemnify, to the fullest extent
permitted by law, members of the Board, its officers, employees and agents and
any and all persons whom it shall have power to indemnify against any and all
expenses, liabilities or other matters.

The effect of these provisions is to eliminate the rights of the Company
and its stockholders (through stockholders' derivative suits on behalf of the
Company) to recover monetary damages against a director or officer for beach
of fiduciary duty (including breaches resulting from grossly negligent
behavior), except in the situations described above.

These provisions will not limit the liability of directors or officers
under the federal securities laws of the United States. This discussion of
Article Seventh of the Company's Certificate of Incorporation, as amended, and
Article VI, Section 5 of the By-Laws is qualified in its entirety by reference
to the relevant provisions of the Certificate of Incorporation (filed as
Exhibit 3.1).

See Item 22 for a statement of the Company's undertaking as to the
Securities and Exchange Commission's position respecting indemnification
arising under the Securities Act of 1933.

herein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the
termination of the offering.

(4) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to

where applicable, each filing of an employee benefit plan's annual report
pursuant to section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the registration statement shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

(5) To deliver or cause to be delivered with the prospectus, to each
person to whom the prospectus is sent or given, the latest annual report to

registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items
of the applicable form.

(7) That every prospectus: (i) that is filed pursuant to paragraph (6)
immediately proceeding, or (ii) that purports to meet the requirements of
Section 10(a)(3) of the Act and is used in connection with an offering of
securities subject to Rule 415, will be filed as a part of an amendment to

B. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

The Company reserves the right, at any time or from time to time, to extend

set forth in "The Exchange Offer--Book-Entry Transfer" section of the

PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

The undersigned hereby tenders to KMC Telecom Holdings, Inc., a Delaware
corporation (the "Company"), the aggregate principal amount of Original Notes
indicated in this Letter of Transmittal, upon the terms and subject to the
conditions set forth in the Company's Prospectus dated December 1, 1999 (the
"Prospectus"), receipt of which is hereby acknowledged, and in this Letter of
Transmittal, which together constitute the Company's offer (the "Exchange
Offer") to exchange $1,000 in principal amount of its 13 1/2% Senior Notes due
May 15, 2009 (the "Exchange Notes"), which have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), for each $1,000 in
principal amount of its issued and outstanding 13 1/2% Senior Notes due May
15, 2009, of which approximately $275.0 million aggregate principal amount was
outstanding on the date of the Prospectus (the "Original Notes" and, together
with the Exchange Notes, the "Notes"). The terms of the Exchange Notes are
substantially identical in all material respects (including principal amount,
interest rate and maturity) to the terms of the Original Notes for which they
may be exchanged pursuant to the Exchange Offer, except that the Exchange
Notes are freely transferable by holders thereof (except as provided herein or
in the Prospectus) and are issued without any right to registration under the
Securities Act. The capitalized terms which are not defined herein are used
herein as defined in the Prospectus.

Subject to, and effective upon, the acceptance for exchange of the Original
Notes tendered hereby, the undersigned hereby sells, assigns and transfers to,
or upon the order of, the Company, all right, title and interest in and to
such Original Notes as are being tendered hereby and hereby irrevocably
constitutes and appoints the Exchange Agent as attorney-in-fact of the
undersigned (with full knowledge that the Exchange Agent is also acting as
agent of the Company in connection with the Exchange Offer) with respect to
such Original Notes, with full power of substitution (such power of attorney
being an irrevocable power coupled with an interest), to

(a) deliver such Original Notes in registered certificated form, or
transfer ownership of such Original Notes through book-entry transfer
at the Book-Entry Transfer Facility, to or upon the order of the
Company, upon receipt by the Exchange Agent, as the undersigned's
agent, of the same aggregate principal amount of Exchange Notes; and

(b) receive, for the account of the Company, all benefits and otherwise
exercise, for the account of the Company, all rights of beneficial
ownership of the Original Notes tendered hereby in accordance with the
terms of the Exchange Offer.

The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Original
Notes tendered hereby and that, when the same are accepted for exchange, the
Company will acquire good, marketable and unencumbered title thereto, free and
clear of all security interests, liens, restrictions, charges, encumbrances,
conditional sale agreements or other obligations relating to their sale or
transfer, and not subject to any adverse claim when the same are accepted by
the Company. The undersigned hereby further represents that any Exchange Notes
acquired in exchange for Original Notes tendered hereby will have been
acquired in the ordinary course of business of the person receiving such
Exchange Notes, whether or not such person is the undersigned, that neither
the holder of such Original Notes nor any such other person has an arrangement
or understanding with any person to participate in the distribution of such
Exchange Notes and that neither the holder of such Original Notes nor any such
other person is an "affiliate," as defined in Rule 405 under the Securities
Act, of the Company. The undersigned has read and agrees to all of the terms
of the Exchange Offer.

The undersigned also acknowledges that the Exchange Offer is being made in
reliance on interpretations by the staff of the Securities and Exchange
Commission (the "SEC"), as set forth in no-action letters issued to third
parties, that the Exchange Notes issued in exchange for the Original Notes
pursuant to the Exchange Offer may be offered for resale, resold and otherwise
transferred by holders thereof (other than any holder that is an "affiliate"
of the Company within the meaning of Rule 405 under the Securities Act),
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such Exchange Notes are

4
<PAGE>

acquired in the ordinary course of such holders' business and such holders
have no arrangement with any person to participate in the distribution of such
Exchange Notes. However, the Company does not intend to request the SEC to
consider, and the SEC has not considered, the Exchange Offer in the context of
a no-action letter, and there can be no assurance that the staff of the SEC
would make a similar determination with respect to the Exchange Offer as in
other circumstances. If the undersigned is not a broker-dealer, the
undersigned represents that it is not engaged in, and does not intend to
engage in, a distribution of Exchange Notes and has no arrangement or
understanding to participate in a distribution of Exchange Notes. If any
holder is an affiliate of the Company, is engaged in or intends to engage in
or has any arrangement or understanding with respect to the distribution of
the Exchange Notes to be acquired pursuant to the Exchange Offer, such holder
(i) could not rely on the applicable interpretations of the staff of the SEC
and (ii) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction.
If the undersigned is a broker-dealer that will receive Exchange Notes for its
own account in exchange for Original Notes acquired as a result of market-
making or other trading activities (a "Participating Broker-Dealer"), it
represents that the Original Notes to be exchanged for the Exchange Notes were
acquired by it as a result of market-making or other trading activities and
acknowledges that it will deliver a prospectus in connection with any resale
of such Exchange Notes, which contains a plan of distribution with respect to
such resale transactions; however, by so acknowledging and by delivering a
prospectus, such Participating Broker-Dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act. The
Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with any resale of Exchange Notes
received for Original Notes where such Original Notes were acquired by a
broker-dealer as a result of market-making or other trading activities (other
than Original Notes acquired directly from the Company).

The Company has agreed that, subject to the provisions of the Registration
Rights Agreement, the Prospectus, as it may be amended or supplemented from
time to time, may be used by a Participating Broker-Dealer in connection with
resales of Exchange Notes received in exchange for Original Notes which were
acquired by such Participating Broker-Dealer for its own account as a result
of market-making or other trading activities, for a period ending 180 days
after the Expiration Date. In that regard, each Participating Broker-Dealer
who acquired Original Notes for its own account as a result of market-making
or trading activities, by tendering such Original Notes and executing this
Letter of Transmittal, agrees that, upon receipt of notice from the Company of
the occurrence of any event or the discovery of any fact which makes any
statement contained or incorporated by reference in the Prospectus untrue in
any material respect or which causes the Prospectus to omit to state a
material fact necessary in order to make the statements contained or
incorporated by reference therein, in light of the circumstances under which
they were made, not misleading, such Participating Broker-Dealer will suspend
the sale of Exchange Notes pursuant to the Prospectus until the Company has
amended or supplemented the Prospectus to correct the misstatement or omission
and has furnished copies of the amended or supplemented Prospectus to the
Participating Broker-Dealer or the Company has given notice that the sale of
the Exchange Notes may be resumed, as the case may be. If the Company gives
such notice to suspend the sale of the Exchange Notes, it shall extend the
180-day period referred to above during which Participating Broker-Dealers are
entitled to use the Prospectus in connection with the resale of Exchange Notes
by the number of days during the period from and including the date of the
giving of such notice to and including the date when Participating Broker-
Dealers shall have received copies of the supplemented or amended Prospectus
necessary to permit resales of the Exchange Notes or to and including the date
on which the Company has given notice that the sale of Exchange Notes may be
resumed, as the case may be.

The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Original Notes tendered hereby. All
authority conferred or agreed to be conferred in this Letter of Transmittal
and every obligation of the undersigned hereunder shall be binding upon the
successors, assigns, heirs, executors, administrators, trustees in bankruptcy
and legal representatives of the undersigned and shall not be affected by, and
shall survive, the death or incapacity of the undersigned. This tender may be
withdrawn only in accordance with the procedures set forth in "The Exchange
Offer--Withdrawal of Tenders" section of the Prospectus.

The undersigned understands that tenders of Original Notes pursuant to any
one of the procedures described in "The Exchange Offer--Procedures for

a binding agreement between the undersigned and the Company upon the terms and
subject to the conditions of the Exchange Offer. The undersigned recognizes
that under certain circumstances set forth in the Prospectus, the Company may
not be required to accept for exchange any of the Original Notes tendered
hereby.

INC. TO EXCHANGE ITS 13 1/2% SENIOR NOTES DUE MAY 15, 2009 FOR ANY AND ALL OF
ITS OUTSTANDING 13 1/2% SENIOR NOTES DUE MAY 15, 2009

1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED
DELIVERY PROCEDURES

This Letter of Transmittal is to be completed by holders of Original Notes
either if certificates are to be forwarded herewith or if tenders are to be
made pursuant to the procedures for book-entry transfer set forth in "The
Exchange Offer--Book-Entry Transfer" section of the Prospectus unless an
Agent's Message is transmitted in lieu thereof. Certificates for all
physically tendered Original Notes or Book-Entry Confirmations, as the case
may be, as well as a properly completed and duly executed Letter of
Transmittal (or manually signed facsimile thereof) or an Agent's Message in
lieu hereof and any other documents required by this Letter of Transmittal,
must be received by the Exchange Agent at the address set forth herein on or
prior to the Expiration Date, or the tendering holder must comply with the
guaranteed delivery procedures set forth below. Original Notes tendered hereby
must be in denominations of principal amount of $1,000 or any integral
multiple thereof.

Holders of Original Notes whose certificates for Original Notes are not
immediately available or who cannot deliver their certificates and all other
required documents to the Exchange Agent on or prior to the Expiration Date,
or who cannot complete the procedure for book-entry transfer on a timely
basis, may tender their Original Notes pursuant to the guaranteed delivery
procedures set forth in the Prospectus under "The Exchange Offer--Guaranteed
Delivery Procedures." Pursuant to such procedures: (i) such tender must be
made through an Eligible Institution (as defined below); (ii) on or prior to
the Expiration Date, the Exchange Agent must receive from such Eligible
Institution a properly completed and duly executed Notice of Guaranteed
Delivery, substantially in the form provided by the Company (by facsimile
transmission, mail or hand delivery), setting forth the name and address of
the holder of Original Notes and the amount of Original Notes tendered,
stating that the tender is being made thereby and guaranteeing that within
three business days after the Expiration Date, the certificates for all
physically tendered Original Notes, or a Book-Entry Confirmation, a properly
completed and duly executed Letter of Transmittal (or a facsimile thereof) or
an Agent's Message in lieu thereof, and any other documents required by this
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent; and (iii) the certificates for all physically tendered
Original Notes, in proper form for transfer, or a Book-Entry Confirmation, a
properly executed Letter of Transmittal (or facsimile thereof) or an Agent's
Message in lieu thereof, as the case may be, and all other documents required
by this Letter of Transmittal, must be received by the Exchange Agent within
three business days after the Expiration Date.

THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE ORIGINAL NOTES
AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE TENDERING
HOLDERS, BUT THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED OR
CONFIRMED BY THE EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, IT IS
RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY
INSURED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO
THE EXCHANGE AGENT PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON THE EXPIRATION
DATE. DO NOT SEND THIS LETTER OF TRANSMITTAL OR ANY ORIGINAL NOTES TO THE
COMPANY OR TO THE BOOK-ENTRY TRANSFER FACILITY.

The Company will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by execution of a Letter of Transmittal (or
facsimile thereof), waives any right to receive any notice of the acceptance
of such tender. See "The Exchange Offer" section of the Prospectus.

<PAGE>

2. PARTIAL TENDER (NOT APPLICABLE TO HOLDERS OF ORIGINAL NOTES WHO TENDER BY
BOOK-ENTRY TRANSFER); WITHDRAWAL RIGHTS.

Tender of Original Notes will be accepted only in the principal amount of
$1,000 and integral multiples thereof. If less than the entire principal
amount of Original Notes evidenced by a submitted certificate is to be
tendered, the tendering holder(s) should fill in the principal amount of
Original Notes to be tendered in the box above entitled "Description of
Original Notes--Principal Amount of Original Notes Tendered." A reissued
certificate representing the balance of nontendered Original Notes will be
sent to such tendering holder, unless otherwise provided in the appropriate
box on this Letter of Transmittal, promptly after the Expiration Date. ALL OF
THE ORIGINAL NOTES DELIVERED TO THE EXCHANGE AGENT WILL BE DEEMED TO HAVE BEEN
TENDERED UNLESS OTHERWISE INDICATED.

Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time on or prior to the Expiration Date. In order for a
withdrawal to be effective on or prior to that time, a written, telegraphic,
telex or facsimile transmission of such notice of withdrawal must be timely
received by the Exchange Agent at one of its addresses set forth above on or
prior to the Expiration Date. Any such notice of withdrawal must specify the
name of the person who tendered the Original Notes to be withdrawn and (if
certificates for such Original Notes have been tendered) the name of the
registered holder of the Original Notes as set forth on the certificate for
the Original Notes, if different from that of the person who tendered such
Original Notes. If certificates for the Original Notes have been delivered or
otherwise identified to the Exchange Agent, then, prior to the physical
release of such certificates for the Original Notes, the tendering holder must
submit the serial numbers shown on the particular certificates for the
Original Notes to be withdrawn and the signature on the notice of withdrawal
must be guaranteed by an Eligible Institution, except in the case of Original
Notes tendered for the account of an Eligible Institution. If Original Notes
have been tendered pursuant to the procedures for book-entry transfer set
forth in "The Exchange Offer--Book-Entry Transfer" section of the Prospectus,
the notice of withdrawal must specify the name and number of the account at
the Book-Entry Transfer Facility to be credited with the withdrawal of
Original Notes, in which case a notice of withdrawal will be effective if
delivered to the Exchange Agent by written, telegraphic, telex or facsimile
transmission. Withdrawals of tenders of Original Notes may not be rescinded.
Original Notes properly withdrawn will not be deemed to have been validly
tendered for purposes of the Exchange Offer, and no Exchange Notes will be
issued with respect thereto unless the Original Notes so withdrawn are validly
retendered. Properly withdrawn Original Notes may be retendered at any
subsequent time on or prior to the Expiration Date by following the procedures
described in the Prospectus under "The Exchange Offer--Procedures for
Tendering."

All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all
parties. Neither the Company, any employees, agents, affiliates or assigns of
the Company, the Exchange Agent nor any other person shall be under any duty
to give any notification of any irregularities in any notice of withdrawal or
incur any liability for failure to give such notification. Any Original Notes
which have been tendered but which are withdrawn will be returned to the
holder thereof without cost to such holder as promptly as practicable after
withdrawal.

3. SIGNATURE ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES.

If this Letter of Transmittal is signed by the registered holder of the
Original Notes tendered hereby, the signature must correspond exactly with the
name as written on the face of the certificates or on a securities position
listing without any change whatsoever.

If any tendered Original Notes are owned of record by two or more joint
owners, all of such owners must sign this Letter of Transmittal.

If any tendered Original Notes are registered in different names on several
certificates or securities positions listings, it will be necessary to
complete, sign and submit as many separate copies of this Letter of
Transmittal as there are different registrations.

10
<PAGE>

When this Letter of Transmittal is signed by the registered holder or
holders of the Original Notes specified herein and tendered hereby, no
endorsements of certificates or separate bond powers are required. If,
however, the Exchange Notes are to be issued, or any untendered Original Notes
are to be reissued, to a person other than the registered holder, then
endorsements of any certificates transmitted hereby or separate bond powers
are required. Signatures on such certificate(s) must be guaranteed by an
Eligible Institution.

If this Letter of Transmittal is signed by a person other than the
registered holder or holders of any certificate(s) specified herein, such
certificate(s) must be endorsed or accompanied by appropriate bond powers, in
either case signed exactly as the name or names of the registered holder or
holders appear(s) on the certificate(s), and the signature(s) on such
certificate(s) must be guaranteed by an Eligible Institution.

If this Letter of Transmittal or any certificates or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing, and, unless waived by the
Company, proper evidence satisfactory to the Company of their authority to so
act must be submitted.

ENDORSEMENTS ON CERTIFICATES FOR ORIGINAL NOTES OR SIGNATURES ON BOND
POWERS REQUIRED BY THIS INSTRUCTION 3 MUST BE GUARANTEED BY A FIRM WHICH IS A
MEMBER OF A REGISTERED NATIONAL SECURITIES EXCHANGE OR A MEMBER OF THE
NATIONAL ASSOCIATION OF SECURITIES DEALERS, INC., BY A COMMERCIAL BANK OR
TRUST COMPANY HAVING AN OFFICE OR CORRESPONDENT IN THE UNITED STATES OR AN
"ELIGIBLE GUARANTOR INSTITUTION" (WITHIN THE MEANING OF RULE 17Ad-15 UNDER THE
EXCHANGE ACT) THAT IS A MEMBER OF THE RECOGNIZED SIGNATURE GUARANTEE PROGRAMS
IDENTIFIED IN THIS LETTER OF TRANSMITTAL (AN "ELIGIBLE INSTITUTION").

SIGNATURES ON THIS LETTER OF TRANSMITTAL MUST BE GUARANTEED BY AN ELIGIBLE
INSTITUTION, UNLESS THE ORIGINAL NOTES ARE TENDERED: (i) BY A REGISTERED
HOLDER OF SUCH ORIGINAL NOTES (WHICH TERM, FOR PURPOSES OF THE EXCHANGE OFFER,
INCLUDES ANY PARTICIPANT IN THE BOOK-ENTRY TRANSFER FACILITY SYSTEM WHOSE NAME
APPEARS ON A SECURITY POSITION LISTING AS THE HOLDERS OF SUCH ORIGINAL NOTES)
WHO HAS NOT COMPLETED THE BOX ENTITLED "SPECIAL DELIVERY INSTRUCTIONS" ON THIS
LETTER OR (ii) FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION.

4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.

Tendering holders of Original Notes should indicate in the applicable box
the name and address to which Exchange Notes issued pursuant to the Exchange
Offer and/or substitute certificates evidencing Original Notes not exchanged
are to be issued or sent, if different from the name or address of the person
signing this Letter of Transmittal. In the case of issuance in a different
name, the employer identification or social security number of the person
named must also be indicated. A holder of Original Notes tendering Original
Notes by book-entry transfer may request that Original Notes not exchanged be
credited to such account maintained at the Book-Entry Transfer Facility as
such holder may designate hereon. If no such instructions are given, such
Original Notes not exchanged will be returned to the name or address of the
person signing this Letter of Transmittal.

5. TAX IDENTIFICATION NUMBER.

Federal income tax law generally requires that a tendering holder whose
Original Notes are accepted for exchange must provide the Company with such
holder's correct Taxpayer Identification Number ("TIN") on Substitute Form W-9
below, which, in the case of a tendering holder who is an individual, is his
or her social security number. If the Company is not provided with the current
TIN or an adequate basis for an exemption, such tendering holder may be
subject to penalties imposed by the Internal Revenue Service. In addition,
delivery to such tendering holder of Exchange Notes may be subject to backup
withholding in an amount equal to 31% of all reportable payments made after
the exchange. If withholding results in an overpayment of taxes, a refund may
be obtained provided that the required information is furnished to the
Internal Revenue Service.

11
<PAGE>

Certain holders of Original Notes (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. See the enclosed Guidelines of
Certification of Taxpayer Identification Number on Substitute Form W-9 (the
"W-9 Guidelines") for additional instructions.

To prevent backup withholding, each tendering holder of Original Notes must
provide its correct TIN by completing the Substitute Form W-9 set forth below,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN) and that (i) the holder is exempt from backup withholding, (ii) the
holder has not been notified by the Internal Revenue Service that such holder
is subject to backup withholding as a result of a failure to report all
interest or dividends or (iii) the Internal Revenue Service has notified the
holder that such holder is no longer subject to backup withholding. If the
tendering holder of Original Notes is a nonresident alien or foreign entity
not subject to backup withholding, such holder must give the Company a
completed Form W-8, Certificate of Foreign Status. These forms may be obtained
from the Exchange Agent. If the Original Notes are in more than one name or
are not in the name of the actual owner, such holder should consult the W-9
Guidelines for information on which TIN to report. If such holder does not
have a TIN, such holder should consult the W-9 Guidelines for instructions on
applying for a TIN, check the box in Part 2 of the Substitute Form W-9 and
write "applied for" in lieu of its TIN. Note: Checking this box and writing
"applied for" on the form means that such holder has already applied for a TIN
or that such holder intends to apply for one in the near future. If such
holder does not provide its TIN to the Company within 60 days, backup
withholding will begin and continue until such holder furnishes its TIN to the
Company.

6. TRANSFER TAXES.

The Company will pay all transfer taxes, if any, applicable to the transfer
of Original Notes to it or its order pursuant to the Exchange Offer. If,
however, Exchange Notes and/or substitute Original Notes not exchanged are to
be delivered to, or are to be registered or issued in the name of, any person
other than the registered holder of the Original Notes tendered hereby, or if
tendered Original Notes are registered in the name of any person other than
the person signing this Letter of Transmittal, or if a transfer tax is imposed
for any reason other than the transfer of Original Notes to the Company or its
order pursuant to the Exchange Offer, the amount of any such transfer taxes
(whether imposed on the registered holder or any other persons) will be
payable by the tendering holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted herewith, the amount of such
transfer taxes will be billed directly to such tendering holder.

EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE ORIGINAL NOTES SPECIFIED IN THIS
LETTER OF TRANSMITTAL.

7. DETERMINATION OF VALIDITY.

The Company will determine, in its sole discretion, all questions as to the
form of documents, validity, eligibility (including time of receipt) and
acceptance for exchange of any tender of Original Notes, which determination
shall be final and binding on all parties. The Company reserves the absolute
right to reject any and all tenders determined by them not to be in proper
form or the acceptance of which, or exchange for which, may, in the view of
counsel to the Company, be unlawful. The Company also reserves the absolute
right, subject to applicable law, to waive any of the conditions of the
Exchange Offer set forth in the Prospectus under the caption "The Exchange
Offer" or any conditions or irregularity in any tender of Original Notes of
any particular holder whether or not similar conditions or irregularities are
waived in the case of other holders.

The Company's interpretation of the terms and conditions of the Exchange
Offer (including this Letter of Transmittal and the instructions hereto) will
be final and binding. No tender of Original Notes will be deemed to have been
validly made until all irregularities with respect to such tender have been
cured or waived. Although the Company intends to notify holders of defects or
irregularities with respect to tenders of Original Notes, neither the Company,
any employees, agents, affiliates or assigns of the Company, the Exchange
Agent, nor any

12
<PAGE>

other person shall be under any duty to give notification of any
irregularities in tenders or incur any liability for failure to give such
notification.

8. NO CONDITIONAL TENDERS.

No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Original Notes, by execution of this Letter
of Transmittal, shall waive any right to receive notice of the acceptance of
their Original Notes for exchange.

9. MUTILATED, LOST, STOLEN OR DESTROYED ORIGINAL NOTES.

Any holder whose Original Notes have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated above for
further instructions. This Letter of Transmittal and related documents cannot
by processed until the procedures for replacing mutilated, lost, stolen or
destroyed certificate(s) have been followed.

10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter of Transmittal, may be
directed to the Exchange Agent at the address and telephone number indicated
above.

11. WAIVER OF CONDITIONS.

Conditions enumerated in the Prospectus may be waived by the Company, in
whole or in part, at any time and from time to time in its reasonable
discretion.

12. INADEQUATE SPACE.

If the space provided herein is inadequate, the aggregate principal amount
of Original Notes being tendered and the certificate number or numbers (if
available) should be listed on a separate schedule attached hereto and
separately signed by all parties required to sign this Letter of Transmittal.
