Item 1.  Business.

Overview

  We are a full service provider of integrated voice and data telecommunication
services on a retail basis to mid-sized and major regional businesses in the
southern United States and a leading regional provider of wholesale long-haul
services to other telecommunications companies. In connection with these
businesses, we own, operate and manage an extensive fiber optic network in the
southern United States.  We had revenues of approximately $244.8 million for the
year ended December 31, 1999, which represents a 42% increase over revenues of
$171.8 million for the year ended December 31, 1998.

  During 1999, we acquired, by merger, AvData Systems, Inc., or "AvData," a
privately owned data network management provider headquartered in Atlanta,
Georgia. We believe this acquisition has strengthened and enhanced our data
services offerings by expanding our current base of data products to include
consulting, integration, operation and proactive management of data networks,
in-depth network performance analysis, and design and implementation services
for data network deployment.

  Also during 1999, we acquired assets of Scientific Telecommunications, Inc.,
or "SciTel," a privately owned telecommunications equipment provider
headquartered in Greenwood, Mississippi. This acquisition expanded our physical
presence in Mississippi to include the Hattiesburg, Tupelo and Greenwood
markets.

  In February 2000, we announced the creation of a new business to be operated
as e/\DeltaCom. We expect that e/\DeltaCom will enable us to extend and enhance
our current data and Internet access products by offering customers collocation
and Web server hosting services integral to operating business-critical
applications over the Internet. In addition to these services, e/\DeltaCom will
provide a wide range of optional configurations and services, including cabinet,
caged and suite space, metered power, network management, firewall management,
disaster recovery, and circuits from customer premises to our network. We expect
e/\DeltaCom to generate

                                       3
<PAGE>

increased Internet access traffic resulting from the connection of e/\DeltaCom's
customers to our existing Internet protocol, or "IP," backbone.

  We were incorporated in Delaware. Our principal executive offices are located
at 1791 O.G. Skinner Drive, West Point, Georgia 31833, and our telephone number
at that address is (706) 385-8000.


Industry Overview

  We operate in the long distance and local telecommunications markets. These
markets continue to undergo substantial changes, including fundamental changes
resulting from the February 8, 1996 enactment of the Telecommunications Act of
1996, which we refer to as the "Telecommunications Act," and the divestiture of
AT&T's local phone systems. We believe that, as a result of continued regulatory
and technological changes and competitive trends, competitive local
telecommunications companies such as ITC/\DeltaCom have substantial
opportunities for growth.

  Long Distance Services.  Until 1984, AT&T largely monopolized local and long
distance telephone services in the United States. Technological developments
gradually enabled others to compete with AT&T in the long distance market. In
1984, largely as the result of a court decree, AT&T was required to divest its
local telephone systems but was permitted to retain its long distance
operations. Since 1984, competition in the long distance market has increased,
service levels have improved, product offerings have increased and prices for
long distance services have generally declined, all of which has resulted in
increased consumer demand and significant market growth for long distance
services. The increase in competition among long distance providers has also
resulted in a growing trend toward industry consolidation.

  Industry sources have estimated that the 1998 aggregate United States revenues
for all toll-based services approximated $105.1 billion.

  Local Services.  The market for local exchange services consists of a number
of distinct service components. These service components are defined by specific
regulatory tariff classifications including:

  .  local network services, which generally include basic dial tone, enhanced
     calling features and data services, including dedicated point-to-point and
     frame relay service;
  .  network access services, which consist of access provided by local exchange
     carriers to long distance network carriers;
  .  short-haul long distance network services, which include intraLATA long
     distance calls, or calls that originate and terminate in the same local
     access and transport area; and
  .  other varied services, including the publication of "white page" and
     "yellow page" telephone directories.

  Industry sources have estimated that the 1998 aggregate United States revenues
for all local services approximated $104.6 billion. Until recently, there was
virtually no competition in the local exchange markets, particularly for local
network and network access services.

  Since 1984, several factors have served to promote competition in the local
exchange market, including:

  .  rapidly growing customer demand for an alternative to the local exchange
     carrier monopoly, influenced partly by the development of competitive
     activities in the long distance market;
  .  advances in the technology for transmission of data and video, which
     require significant capacity and reliability levels;
  .  the development of fiber optics and digital electronic technology, which
     have reduced network construction costs while increasing transmission
     speeds, capacity and reliability compared to copper-based networks;

                                       4
<PAGE>

  .  the significant access charges interexchange carriers are required to pay
     to local exchange carriers to access the local exchange carriers' networks;
     and
  .  a willingness on the part of legislators to enact and regulators to enforce
     legislation and regulations permitting and promoting competition in the
     local exchange market.

  The Telecommunications Act requires all local exchange carriers
to "unbundle" their local network offerings and allow other providers of
telecommunications services to interconnect with their facilities and equipment.
Most significantly, the incumbent local exchange carriers are required to
complete local calls originated by our customers and switched by us and to
deliver inbound local calls to us for termination to our customers, assuring
customers of unimpaired local calling ability. We expect to obtain access to
incumbent carrier local "loop" facilities, which are the transmission lines
connecting customers' premises to the public telephone network, on an unbundled
basis at reasonable rates. In addition, local exchange carriers are obligated to
provide local number portability and dialing parity upon request and make their
local services available for resale by competitors. Local exchange carriers also
are required to allow competitors non-discriminatory access to local exchange
carrier pole attachments, conduit space and other rights-of-way. Moreover,
states may not erect "barriers to entry" of local competition, although they may
regulate such competition.

Services and Facilities

  Services.  We currently provide two basic services: (1) full service
integrated voice and data telecommunication services on a retail basis, which we
refer to as our "retail services," and (2) wholesale long-haul services to other
telecommunications companies, which we refer to as our "carriers' carrier
services."

  Retail Services. Our retail services involve the provision of voice, data or
video telecommunications services to end users or resellers. These retail
services include:

  . local exchange services;
  . long distance services;
  . toll calling, calling card and operator services;
  . Asynchronous Transfer Mode, or "ATM," frame relay and high capacity
    broadband private line services;
  . primary rate interface connectivity and collocation services to Internet
    service providers, or "ISPs";
  . enhanced services, including conference calling, fax broadcasting and pre-
    paid calling cards;
  . consulting, integration, operation and proactive management of data
    networks:
  . in-depth network performance analysis and implementation and design services
    for data network deployment;
  . Internet, intranet and Web page hosting services; and
  . customer premise equipment sales, installation and repair.

  We intend to provide additional types of retail services in the future and
expand the markets in which we offer local services as part of a bundled ``one-
stop'' integrated telecommunications service, which will offer customers a wide
range of switch-based value-added services. Our customer-focused software and
network architecture permits us to present our customers with one fully
integrated monthly billing statement for the entire package of retail services.

  Local Services.  We currently provide local exchange services by (1) reselling
the services of incumbent local exchange carriers and (2) using our own local
switching facilities. Over time, we expect to provide local services primarily
using our own switching facilities and existing regional fiber optic network,
supplemented by unbundled facilities of incumbent local exchange carriers or
other competitive local exchange carriers. We offer local exchange services in
32 of the 33 markets in

                                       5
<PAGE>

which we currently provide retail services and expect to offer local services in
a total of 40 markets by the end of 2000.

  Long Distance.  We offer a full range of retail long distance services,
including traditional switched and dedicated long distance, toll calling,
international, calling card and operator services.

  Data Services.  We provide high quality data services to our customers
primarily using frame relay switches distributed strategically throughout our
network.  This enables customers to use a single network connection to
communicate with multiple sites throughout our fiber optic network. We provide
ATM services both on a resale basis and by using our own network.  We provide
data services to customers, such as banks and local and state governments, that
need to transmit large amounts of data within our service region. We will
continue to seek, through strategic business relationships with other providers,
to interconnect our fiber optic network with the fiber optic networks of other
companies. We anticipate increased demand for data services in the future, and
expect that in the future a larger percentage of our revenues will be derived
from the sale of data services.

  During 1999, we increased our data and related service offerings with the
acquisition of AvData.  New or expanded services offerings resulting from this
acquisition include consulting, integration, operation and proactive management
of data networks, with 24 x 7 monitoring, and trouble shooting, problem
resolution and comprehensive network performance reporting for corporate
networks.  In addition, this acquisition enabled us to add to our product mix
in-depth network performance analysis and design and implementation services for
data network deployment.

  Internet Access, Intranet Services and Web Development.  We provide dedicated
frame relay, Internet access and intranet services, electronic mail and Web
hosting services. We expect that mid-sized and larger businesses will require
faster Internet access and larger bandwidth in the future, and we intend to
offer products that will meet that demand.

  ISP Local Telecommunications Services.  We provide local wholesale
telecommunications services to ISPs such as primary rate interface connectivity
between our network and the network of the ISP.  In addition, we provide
equipment collocation services to permit the ISP to collocate its modems,
routers or network servers with our switching facilities.

  Customer Premise Equipment.  We sell, install and repair customer premise
equipment such as telephones, office switchboard systems and, to a lesser
extent, private branch exchanges, or "PBX," for customers in the following
markets:

  . Anniston, Birmingham, Dothan, Florence, Huntsville, Mobile and Montgomery,
    Alabama;
  . Atlanta and Columbus, Georgia;
  . Jacksonville, Ocala and Pensacola, Florida;
  . Baton Rouge, Louisiana;
  . Greenwood, Hattiesburg, Jackson and Tupelo, Mississippi;
  . Charlotte and Greensboro, North Carolina; and
  . Charleston, Columbia and Greenville, South Carolina.

We intend to offer customer premise equipment sales, installation and repair in
additional markets in the future, with the goals of augmenting and supporting
our sale of local and long distance services and enhancing customer retention.

  Carriers' Carrier Services.  Our carriers' carrier services are used by
customers, such as major telecommunications carriers and non-facilities based
carriers that have switches but do not own transmission facilities, to transport
their already-switched traffic between local access and transport areas, or
"LATAs," which are geographic areas composed of contiguous local exchanges.
Calls being transmitted over a long-haul circuit for a customer are generally
routed by the customer through a

                                       6
<PAGE>

switch to a receiving terminal in our network. We transmit the signals over a
long-haul circuit to the terminal where the signals are to exit our network. The
customer then routes the signals through another switch and to the call
recipient through a local exchange carrier. We provide DS-1, DS-3 and OC-N
services. OC-N services are used by our customers for very high capacity inter-
city connectivity and specialized high-speed data networking. The interface
between our network and the customer's facilities is by either local exchange
carrier or a direct connection between our network and the facilities of the
customer. We typically bill the customers a fixed monthly rate depending on the
capacity and length of the circuit, regardless of the amount the circuit is
actually used.

  e/\DeltaCom Services. In February 2000, we announced the creation of a new
business to be operated as e/\DeltaCom. We expect that e/\DeltaCom will enable
us to extend and enhance our current data and Internet access products by
offering customers collocation and Web server hosting services integral to
operating business-critical applications over the Internet. In addition to these
services, e/\DeltaCom will provide a wide range of optional configurations and
services, including cabinet, caged and suite space, metered power, network
management, firewall management, disaster recovery, and circuits from customer
premises to our network. We expect e/\DeltaCom to generate increased Internet
access traffic resulting from the connection of e/\DeltaCom's customers to our
existing Internet protocol, or "IP," backbone.

  Facilities.  We own or manage approximately 8,250 route miles of a high
quality fiber optic network which covers portions of ten states in the southern
United States and extends to over 100 points of presence, or "POPs." These POPs
are located in almost all major population centers in the areas covered by our
fiber optic network and in a significant number of smaller cities where our only
competitor is the incumbent local exchange carrier.

  We own approximately 4,550 route miles of our fiber optic network, which we
have built or acquired since 1992. In addition, we have strategic relationships
principally with three public utilities, Duke Power Company, Florida Power &
Light Company and Entergy Technology Company, pursuant to which we market, sell
and manage capacity on approximately 3,700 route miles of network owned and
operated by these three utilities.

  In addition, we are able to purchase network capacity to certain cities not
covered by our owned and managed network in North Carolina and South Carolina
under a buy-sell agreement with Carolinas FiberNet, LLC, which manages fiber
optic facilities in the two states. This agreement enables the parties to buy
and sell capacity on each other's networks at pre-established prices, which are
generally more favorable than the prices for such capacity available in the open
market. Under this agreement, neither party is responsible for network
maintenance charges relating to the other party's network.

  We expect to add approximately 1,000 to 1,500 owned and operated route miles
to our fiber network by the end of 2000 through a combination of construction
and long-term dark fiber leases. In addition, as part of our strategy, we intend
to continue to evaluate the potential expansion of our network through a
combination of new construction, long-term dark fiber leases and fiber swap
transactions, depending on the extent of capital required over the economic life
of the fiber assets we will deploy.  Our decision to expand our fiber optic
network will be based on various factors, including the number of our customers
in a market, the anticipated operating cost savings associated with such
construction, and any strategic relationships with owners of existing
infrastructure, including utilities and cable operators.  Through our strategic
relationships with public utility companies, we believe that we will be able to
achieve capital efficiencies in constructing and expanding our fiber optic
network in a rapid and cost-effective manner. We also believe that our fiber
optic network, in combination with our personalized approach to customer
service, will create an attractive customer-focused platform for the provision
of local, long distance and enhanced services.

  We have implemented electronic redundancy throughout our network, which
enables traffic to be rerouted to another fiber in the same fiber sheath in the
event of a partial fiber cut or electronic failure. In addition, approximately
65% of our owned and operated fiber optic network is protected by

                                       7
<PAGE>

geographically diverse routing, a network design also called a "self healing
ring." This network design enables traffic to be rerouted to an entirely
different fiber optic cable, assuming capacity is available, in the event of a
total cable cut.

  Our switching facilities currently consist of a Nortel DMS-250 switch in Arab,
Alabama and Nortel DMS-500 switches in the following locations:

  .     Anniston, Birmingham and Montgomery, Alabama;
  .     Jacksonville and Ocala, Florida;
  .     Atlanta, Georgia;
  .     Gulfport, Mississippi;
  .     Greensboro, North Carolina; and
  .     Columbia, South Carolina.

The Nortel DMS-500 switches are capable of handling both local and long distance
traffic, while the Nortel DMS-250 switch is capable on handling long distance
only.

  These installations enable us to market our retail services, including local
services, on a switch-based facilities basis in, among other markets:

  .     Anniston, Birmingham, Florence, Huntsville, Montgomery, and Mobile,
        Alabama;
  .     Jacksonville, Ocala and Orlando, Florida;
  .     Atlanta, Georgia;
  .     Gulfport, Mississippi;
  .     Charlotte and Greensboro, North Carolina; and
  .     Charleston, Columbia and Greenville, South Carolina.

We expect to place Nortel DMS-500 switches into service in Miami, Florida,
Nashville, Tennessee and Houston, Texas by the end of 2000.

  We intend to place additional switches strategically along our fiber optic
network over the next several years. We also intend to deploy a significant
number of Nortel Access Nodes in the majority of the markets we intend to serve.
The additional switches and nodes will allow us to perform local and long
distance switching in our markets on a host/remote type relationship to the
applicable Nortel DMS-500 switch. The Nortel Access Nodes will be connected to
our Nortel DMS-500 switching platform, utilizing our fiber optic network
wherever possible. This networking design, together with our interconnection
agreement with BellSouth, will enable us to be a facilities-based provider of
local and long distance services in all of the markets that we intend to enter.

  We are a member of the Associated Communications Companies of America, an
eleven-member trade association that negotiates with carriers for wholesale
telecommunications services for its members. The collective buying power of its
members enables the association to negotiate as if it were one of the larger
long distance providers in the United States.

  Our data network consists of 17 Ascend 9000 frame relay switches located in:

  .       Anniston (two switches), Arab, Birmingham (two switches), Mobile and
          Montgomery, Alabama;
  .       Jacksonville and Ocala, Florida;
  .       Atlanta (two switches) and West Point, Georgia;
  .       Gulfport and Jackson, Mississippi;
  .       Greensboro, North Carolina;
  .       Columbia, South Carolina; and
  .       Dallas, Texas

                                       8
<PAGE>

Our data network connects with the frame relay networks of BellSouth and other
carriers to provide nationwide connectivity for our customers.  Our Ascend frame
relay switches have the capability to provide ATM connectivity. Over the next
several years, we intend to collocate additional frame relay and ATM switches
with our Nortel DMS-500 switches at strategic network facility locations to
create a data backbone which will support our data services.

  In October 1999, our advanced IP network became operational. We have installed
12 Cisco GSR routers and 14 Cisco 7513 edge routers at strategic points on this
IP network. We expect to expand this network during 2000 as we place routers at
various strategic points.


Sales and Marketing

  Retail Services.  We focus our sales efforts on mid-sized and major regional
businesses in the southern United States. Our sales force, composed of direct
sales personnel, technical consultants and technicians, markets our
telecommunications services. Our management believes that high quality employee
training is a prerequisite for superior customer service, and as a result each
member of our sales force is required to complete our intensive training
program. Our marketing strategy is built upon the belief that customers prefer
to hold one company accountable for all of their telecommunications services.
Each branch office provides technical assistance for its voice, data, Internet
and customer premise equipment as required. Customers are assured a single point
of contact, 24 hours a day, seven days a week.

  At December 31, 1999, 196 direct sales personnel conducted marketing of our
retail services to mid-sized and major regional businesses. Such personnel are
located in 34 branch offices in 33 markets in the southern United States. We
significantly expanded our sales force in 1999 and we expect to continue to
expand our direct sales force as well as open branch offices in additional major
and secondary population centers in the southern United States during 2000. Our
sales personnel make direct calls to prospective and existing business
customers, conduct analyses of business customers' usage histories and service
needs, and demonstrate how our service package will improve a customer's
communications capabilities and costs. Sales personnel locate potential business
customers by several methods, including customer referral, market research,
telemarketing and other networking alliances such as endorsement agreements with
trade associations and local chambers of commerce. Our sales personnel work
closely with our network engineers and information systems consultants to design
new service products and applications. Our branch offices are also primarily
responsible for coordinating service and customer premise equipment installation
activities. Technicians survey customers' premises to assess power and space
requirements, and coordinate delivery, installation and testing of equipment.

  A primary element of our retail services marketing strategy is to enter into
contracts with our customers. Those agreements generally provide for payment in
arrears based on minutes of use for switched services and in advance for private
line services. The agreements generally also provide that the customer may
terminate the affected service without penalty in the event of substantial and
prolonged outages arising from causes within our control, and for certain other
defined causes. Generally, the agreements provide that the customer must utilize
at least a minimum dollar amount, measured by dollars or minutes of use, of
switched long distance services per month for the term of the agreement.

  In addition, we market our business communication services through
advertisements, event sponsorships, trade journals, direct mail and trade
forums. Because we intend to distinguish our retail products largely based on
the convenience of our single communications bundle and the benefits of our
comprehensive, individualized and innovative customer support, we continue to
believe that advertising will play a significant role in our marketing strategy.

  Carriers' Carrier Services.  We have long-haul circuit contracts with major
long distance carriers, including AT&T, MCI WorldCom, Inc., Sprint Corporation,
Qwest Communications

                                       9
<PAGE>

International, Inc., Cable & Wireless Communications, Inc., Frontier
Communications Services and Broadwing, Inc. As of December 31, 1999, we had
remaining future long term contract commitments totaling approximately $114.2
million. These contracts expire on various dates through 2008 and are expected
to generate approximately $103.3 million in revenues for us through 2004. We
also provide long-haul transmission to customers after contract expiration on a
month-to-month basis. Our long-haul contracts provide for fixed monthly
payments, generally in advance. Although sales volumes from particular customers
vary from year to year, we have historically enjoyed high customer retention and
circuit renewal rates.

Competition

  The telecommunications industry is highly competitive. We compete primarily on
the basis of price, availability, transmission quality, reliability, customer
service and variety of product offerings. Our ability to compete effectively
depends on our ability to maintain high quality services at prices generally
equal to or below those charged by our competitors. In particular, price
competition in the retail and carrier's carrier long distance markets has
generally been intense and is expected to increase. Our competitors include,
among others, AT&T, Sprint and MCI WorldCom on an interexchange basis and
BellSouth on an intraLATA basis. These companies, among others, have
substantially greater financial, personnel, technical, marketing and other
resources, larger numbers of established customers and more prominent name
recognition than us and utilize more extensive transmission networks than us. In
addition, companies such as Broadwing, Qwest and Williams Communications have
constructed or are constructing nationwide fiber optic systems, including routes
through portions of the southern United States. We also increasingly face
competition in the long distance market from local exchange carriers, switchless
resellers, cable companies and satellite carriers and may eventually compete
with public utilities. We also may increasingly face competition from firms
offering long distance data and voice services over the Internet. Such firms
could enjoy a significant cost advantage because at this time they do not pay
carrier access charges or universal service fees.

  Our principal competitor for local exchange services will be the incumbent
local exchange carrier in the particular market, including BellSouth in a large
majority of our market areas. The incumbent local exchange carriers enjoy
substantial competitive advantages arising from their historical monopoly
position in the local telephone market, including their pre-existing customer
relationship with all or virtually all end users. Furthermore, we are highly
dependent on the competing incumbent local exchange carrier, or "ILEC," for
local network facilities and wholesale services required in order for us to
assemble our own local retail products. We also face competition from
competitive local exchange carriers, or "CLECs," some of whom have already
established local operations in our target markets.  In addition, incumbent
local exchange carriers are expected to compete in each other's markets in some
cases.  BellSouth has plans to provide local services within its geographic
region in competition with independent telephone companies. Wireless
telecommunications providers may develop into effective substitutes for wireline
local telephone service.  For information about the interconnection risks to our
business, see ``Risk Factors--If we are unable to interconnect with BellSouth
and incumbent local exchange carriers on acceptable terms, our ability to offer
local telephone services will be adversely affected.''

  Local and long distance marketing is converging as other carriers besides us
offer integrated retail product lines.  For example, many CLECs offer long
distance service to their customers and large long distance carriers such as
AT&T, Sprint and MCI WorldCom have begun to offer local services in certain
markets. We also compete with numerous direct marketers and telemarketers and
equipment vendors and installers with respect to certain portions of our
business.

  Regional Bell Operating Companies, or "RBOCs," such as BellSouth are allowed
to provide interLATA long distance services outside their home regions, as well
as interLATA mobile services within their regions. Under the Telecommunications
Act, the RBOCs will be allowed to provide interLATA long distance services
within their regions after meeting certain requirements intended to foster
opportunities for local telephone competition. The RBOCs already have extensive
fiber optic cable, switching, and other network facilities in their respective
regions that can be used for their

                                       10
<PAGE>

long distance services. BellSouth and other RBOCs are taking significant steps
toward obtaining approval to provide in-region long distance services. The
Federal Communications Commission, or the "FCC," forced the withdrawal of the
first RBOC request for in-region long distance authority, and had rejected all
other applications, including applications by BellSouth, until their approval of
Bell Atlantic's application in New York. However, SBC's application for approval
in Texas is now pending before the FCC, and additional interLATA
applications are expected to be filed in 2000. There can be no assurance that
such approvals will be delayed until local competition is established.

  A continuing trend toward consolidation, mergers, acquisitions and strategic
alliances in the telecommunications industry could also increase the level of
competition faced by our carriers' carrier customers or us. For example,
WorldCom acquired MCI in September 1998, AT&T acquired Tele-Communications, Inc.
in March 1999 and SBC Communications, Inc. acquired Ameritech Corporation in
October 1999. In addition, Bell Atlantic Corporation and GTE Corporation have
announced merger plans and have already completed many of the steps needed to
consummate the merger. Qwest's proposed merger with US WEST, Inc., MCI
WorldCom's proposed merger with Sprint and America Online, Inc.'s proposed
merger with Time Warner, Inc. are also awaiting regulatory approval. In January
2000, AT&T and British Telecommunications plc entered a joint venture, Concert,
to combine the international assets and operations of each company, including
their existing international networks. In addition, SBC and Williams
Communications Group, Inc., a long distance company, entered a strategic
alliance pursuant to which the two companies would supply services to each
other. The telecommunications market is very dynamic, and additional competitive
changes are likely in the future.

Regulation

  Overview.  Our services are subject to federal, state and local regulation.
Through our wholly owned subsidiaries, we hold various federal and state
regulatory authorizations. The FCC exercises jurisdiction over
telecommunications common carriers to the extent they provide, originate or
terminate interstate or international communications. The FCC also establishes
rules and has other authority over certain issues related to local telephone
competition. State regulatory commissions retain jurisdiction over
telecommunications carriers to the extent they provide, originate or terminate
intrastate communications. Local governments may require us to obtain licenses,
permits or franchises in order to use the public rights of way necessary to
install and operate our networks.

  Federal Regulation.  We are categorized as a non-dominant carrier by the FCC,
and as a result are subject to relatively limited regulation of our interstate
and international services. Certain general policies and rules apply, as well as
certain reporting requirements, but our rates are not reviewed. We have all the
operating authority required by the FCC to conduct our long distance business.
As a non-dominant carrier, we may install and operate additional facilities for
the transmission of domestic interstate communications without prior FCC
authorization, except to the extent that radio licenses are required.

  The FCC's role with respect to local telephone competition arises principally
from the Telecommunications Act, which became effective February 8, 1996.  The
Telecommunications Act pre-empts state and local laws to the extent that they
prevent competitive entry into the provision of any telecommunications service.
Subject to this limitation, however, the state and local governments retain
telecommunications regulatory authority.  The Telecommunications Act imposes a
variety of new duties on local exchange carriers, including non-incumbent local
exchange carriers such as us, in order to promote competition in local exchange
and access services.  These duties include requirements to:

  .     complete calls originated by competing carriers on a reciprocal basis;
  .     permit resale of services;
  .     permit users to retain their telephone numbers when changing carriers;
        and
  .     provide competing carriers access to poles, ducts, conduits and rights-
        of-way at regulated prices.

  Incumbent local exchange carriers are also subject to additional requirements.
These duties include obligations of the incumbent local exchange carriers to:

                                       11
<PAGE>

  .     interconnect their networks with competitors;
  .     offer collocation of competitors' equipment at their premises;
  .     make available elements of their networks, including network facilities,
        features and capabilities, on non-discriminatory, cost-based terms; and
  .     offer wholesale versions of their retail services for resale at
        discounted rates.

  Collectively, these requirements recognize that local exchange competition is
dependent upon cost-based and non-discriminatory interconnection with and use of
incumbent local exchange carrier networks.  Failure to achieve such
interconnection arrangements could have an adverse impact on our ability or
other entities' ability to provide competitive local exchange services.  Under
the Telecommunications Act, incumbent local exchange carriers are required to
negotiate in good faith with carriers requesting any or all of the above
arrangements.  In addition, in August 1996, the FCC released a decision, or the
"Interconnection Decision," implementing the interconnection portions of the
Telecommunications Act.  The FCC subsequently adopted further specific rules to
implement these requirements.  The Interconnection Decision has been the subject
of significant legal dispute.  In January 1999, the U.S. Supreme Court rejected
challenges to the Interconnection Decision and affirmed the authority of the FCC
to establish rules governing interconnection.  We believe that additional
disputes regarding the Interconnection Decision and other related FCC actions
are likely.

  There can be no assurance that the FCC's rules, together with rules adopted by
state public utility commissions, will be implemented in a manner that will
permit local telephone competition to develop to a substantial extent and
without significant delays. For example, many new carriers, including us, have
experienced problems with respect to the operations support systems used by new
carriers to order and receive network elements and wholesale services from the
incumbent local exchange carriers. These systems are necessary for new carriers
like us to provide local service to customers on a timely and competitive basis.
The FCC has created a task force to examine problems that have slowed the
development of local telephone competition but as yet has taken no enforcement
actions. In September 1999, the FCC adopted revised rules defining the
circumstances under which incumbent local exchange carriers must make network
elements available to competitors. In a number of ways, these rules are more
favorable to competitors than the rules that were in effect prior to the Supreme
Court's January 1999 decision to the original 1996 rules. In January 1999, the
Supreme Court had reversed an Eighth Circuit Court of Appeals decision that had
overturned a number of the FCC's original interconnection rules. The FCC's 1999
rules and the FCC's pricing methodology for network elements still are subject
to judicial challenge, however. In addition, in some instances the new rules
offer less to competitors than the previous rules, by restricting in some
respects the availability of certain network elements and by limiting in certain
respects the services that competitors can provide over those elements. Any
restriction on the availability of network elements could have a materially
adverse effect on us.

  We entered into an interconnection agreement with BellSouth. This
interconnection agreement currently allows us to provide local service on either
a resale basis or by purchasing all unbundled network elements required to
provide local service on a facilities basis, without using Company-owned
facilities. We agreed with BellSouth on interim pricing terms for such resale
and purchase of unbundled network elements. The public utilities commissions, or
the "PUCs," regulating our markets approved the terms of the interconnection
agreement, the initial term of which has expired. Pursuant to section XVII of
the interconnection agreement, however, the rates, terms and conditions of the
interconnection agreement remain in effect while we are in arbitration with Bell
South with respect to new terms and conditions. The BellSouth interconnection
agreement however does not resolve all operational issues, particularly those
relating to the collocation of our equipment with that of BellSouth.
Strengthened equipment collaboration requirements were adopted by the FCC in
1999 but portions of the FCC decision were recently sent back to the FCC for
reconsideration by the reviewing court. We expect that the new BellSouth
interconnection agreement will provide a foundation for us to provide local
service on a reasonable commercial basis, but there can be no assurance in this
regard and important issues remain unsettled. See ``Risk Factors--If we are
unable to interconnect with BellSouth and incumbent local exchange carriers on
acceptable terms, our ability to offer local telephone services will be
adversely affected.''

  We have negotiated or obtained through Section 252(i) of the
Telecommunications Act similar interconnection agreements with other incumbent
local exchange carriers, including interconnection agreements with GTE, Sprint
and SBC Communications.  However, other carriers who have preceded us in the
negotiation process with certain of these incumbent local exchange carriers have
expressed dissatisfaction with some of the terms of their agreements, or with
the operational support systems by which they obtain the interconnection they
require to provide local services to end users.

  The Telecommunications Act also eliminates previous prohibitions on the
provision of interLATA long distance services by the RBOCs and GTE.  The RBOCs
are permitted to provide interLATA long distance service outside those states in
which they provide local exchange service, or "out-of-region long distance
service," upon receipt of any necessary state and/or federal regulatory
approvals that

                                       12
<PAGE>

are otherwise applicable to the provision of intrastate and/or
interstate long distance service.  Under the Telecommunications Act, the RBOCs
will be allowed to provide long distance service within the regions in which
they also provide local exchange service, or "in-region service," on a state-by-
state basis upon specific approval of the FCC and satisfaction of other
conditions, including a checklist of interconnection requirements intended to
open local telephone markets to competition.  As of the date hereof, the FCC has
only approved Bell Atlantic's application in New York.  If the FCC permits
BellSouth to provide long distance service in its local service regions before
meeting our local interconnection needs, BellSouth would be able to duplicate
our integrated local and long distance services and could have a significant
competitive advantage in marketing those services to its existing local
customers.

  The Telecommunications Act also imposes other restrictions on the RBOCs in
connection with their entry into the interLATA long distance services market.
Among other things, for the first three years, unless extended by the FCC, the
RBOCs must pursue such activities only through separate subsidiaries with
separate books and records, financing, management and employees.  In addition,
affiliate transactions with these subsidiaries must be conducted on a non-
discriminatory basis.

  In the future, an important element of providing competitive services may be
the ability to offer customers high-speed broadband local connections.  The FCC
is considering a proposal that would allow incumbent local exchange carriers to
offer these and other services through separate affiliates, in which case their
network elements for providing these services would not need to be made
available to us or other competitors. The FCC recently approved a similar
structure in connection with the SBC/Ameritech merger. AT&T has entered
arrangements with cable companies for the exclusive use of their local networks
for broadband telecommunications and several cable companies are offering
broadband Internet access over their network facilities. If we are unable to
meet future demands of our customers for broadband local access on a timely
basis at competitive rates, we may be at a significant competitive disadvantage.

  The FCC also regulates the interstate access rates charged by incumbent local
exchange carriers for the origination and termination of interstate long
distance traffic. These access rates make up a significant portion of the cost
of providing long distance service. The FCC is in the process of implementing
access policy changes that over time are expected to reduce access rates, and
hence the cost of providing long distance service, especially to business
customers. However, further FCC action in this area is necessary and the full
impact of the FCC's decisions will not be known until those decisions are
implemented over the next several years.

  In a related proceeding, the FCC has adopted changes to the methodology by
which access has been used in part to subsidize universal telephone service and
other public policy goals. Telecommunications providers like us now pay a fee
calculated as a percentage of their revenues to support these goals.  Certain
individual states are also implementing universal service funds.  The full
implications of these decisions also remain uncertain and subject to change.

  In addition, the FCC continues to consider related questions regarding the
applicability of access charges and universal service fees to ISPs.  Currently,
ISPs are not subject to these expenses and the U.S. Court of Appeals for the
Eighth Circuit, or the "Eighth Circuit," has upheld the FCC's decision not to
impose such fees.  However, the incumbent local exchange carriers and other
parties argue that this exemption unfairly advantages ISPs, particularly when
they provide data, voice or other services in direct competition with
conventional telecommunications.  We are not in a position to determine how
these access and universal service matters will be resolved in the future, and
whether or not such resolution will be harmful to our competitive position.

  The FCC also imposes prior approval requirements on transfers of control and
assignments of radio licenses and operating authorizations. The FCC has the
authority generally to condition, modify, cancel, terminate or revoke licenses
and operating authority for failure to comply with federal laws and/or the
rules, regulations and policies of the FCC. Fines or other penalties also may be
imposed for such violations. There can be no assurance that the FCC or third
parties will not raise issues with regard to our compliance with applicable laws
and regulations.

                                       13
<PAGE>

  As a general matter, no assurance is possible regarding how quickly or how
adequately we will be able to take advantage of the opportunities created by the
Telecommunications Act. We could be adversely affected if a court decision
reversing some of the new FCC rules, or problems in the related arbitration and
negotiation process, were to result in increasing the cost of using incumbent
local exchange carrier network elements or services, or if such actions
otherwise were to result in delays in the implementation of the
Telecommunications Act or impediments to the development of local telephone
competition.

  The FCC has granted incumbent local exchange carriers certain flexibility in
pricing their interstate special and switched access services. Under this
pricing scheme, local exchange carriers may establish pricing zones based on
access traffic density and charge different prices for access provided in each
zone. The FCC recently granted incumbent local exchange carriers additional
pricing flexibility as local competition develops in their markets. There can be
no assurance that such pricing flexibility will not place us at a competitive
disadvantage, either as a purchaser of access for our long distance operations,
or as a vendor of access to other carriers or end user customers.

  State Regulation.  We are also subject to various state laws and regulations.
Most PUCs require providers such as us to obtain authority from the commission
prior to the initiation of service. In most states, including Alabama, Georgia
and Florida, we also are required to file tariffs setting forth the terms,
conditions and prices for services that are classified as intrastate. We also
are required to update or amend our tariffs when we adjust our rates or add new
products, and we are subject to various reporting and record-keeping
requirements.

  Many states also require prior approval for transfers of control of certified
carriers, corporate reorganizations, acquisitions of telecommunications
operations, assignment of carrier assets, carrier stock offerings and incurrence
by carriers of significant debt obligations. Certificates of authority can
generally be conditioned, modified, canceled, terminated or revoked by state
regulatory authorities for failure to comply with state law and/or the rules,
regulations and policies of state regulatory authorities. Fines or other
penalties also may be imposed for such violations. There can be no assurance
that PUCs or third parties will not raise issues with regard to our compliance
with applicable laws or regulations.

  We have all necessary authority to offer intrastate long distance services in
Alabama, Arkansas, Arizona, California, Colorado, Connecticut, Delaware,
District of Columbia, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa,
Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan,
Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New
Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma,
Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee,
Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin and
Wyoming.  An application for authority to provide intrastate long distance is
pending in Alaska. We seek authority to provide long distance service in states
outside of our target markets to enhance our ability to attract business
customers with offices, or whose employees travel, outside of our target
markets.

  We provide local exchange services in our region by reselling the retail local
services of the incumbent local exchange carrier in a given territory and, in
some established markets, using incumbent network elements and our own local
switching facilities. We have obtained authority to provide competitive local
exchange services in Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana,
Mississippi, North Carolina, South Carolina, Tennessee and Texas.

  Many issues remain open regarding how new local telephone carriers will be
regulated at the state level. For example, although the Telecommunications Act
pre-empts the ability of states to

                                       14
<PAGE>

forbid local service competition, the Telecommunications Act preserves the
ability of states to impose reasonable terms and conditions of service and other
regulatory requirements. However, these statutes and related questions arising
from the Telecommunications Act will be elaborated further through rules and
policy decisions made by PUCs in the process of addressing local service
competition issues.

  We also will be affected by state PUC decisions related to the incumbent local
exchange carriers despite the recent U.S. Supreme Court decisions upholding the
FCC's rule making power under the Telecommunications Act. For example, PUCs have
responsibility under the Telecommunications Act to oversee relationships between
incumbent local exchange carriers and their new competitors with respect to such
competitors' use of the incumbent local exchange carriers' network elements and
wholesale local services. PUCs arbitrate interconnection agreements between the
incumbent local exchange carriers and new competitors such as us when necessary.
Important issues remain open regarding both the scope of PUC authority in this
area and the extent to which PUCs will adopt policies that promote local
exchange competition.  It is too early to evaluate how these matters will be
resolved, or their impact on our ability to pursue our business plan.

  States also regulate the intrastate carrier access services of the incumbent
local exchange carriers. We are required to pay such access charges to originate
and terminate our intrastate long distance traffic. We could be adversely
affected by high access charges, particularly to the extent that the incumbent
local exchange carriers do not incur the same level of costs with respect to
their own intrastate long distance services. In a related development, states
also will be developing intrastate universal service charges parallel to the
interstate charges created by the FCC. For example, incumbent local exchange
carriers such as BellSouth advocate the formation of state-level funds that
would be supported by potentially large payments by firms such as ours based on
their total intrastate revenues.  Another issue is use by certain incumbent
local exchange carriers, with the approval of PUCs, of extended local area
calling that converts otherwise competitive intrastate toll service to local
service. States also are or will be addressing various intraLATA dialing parity
issues that may affect competition. Our business could be adversely affected by
these or other developments.

  We also will be affected by how states regulate the retail prices of the
incumbent local exchange carriers with which we compete. We believe that, as the
degree of intrastate 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 lower prices than they otherwise could. In a
related development, BellSouth has obtained authority to create ``CLEC''
affiliates that would operate on a much less regulated basis and therefore could
provide significant competition in the business market whether or not the
traditional BellSouth local business receives more pricing flexibility.
Currently, Kentucky has placed limitations on such CLEC affiliates and Tennessee
has refused BellSouth's affiliate CLEC applications.  We cannot predict the
extent to which these developments may impact our business.

  Local Government Authorizations and Related Rights of Way.  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 linear foot basis. There can be no assurance that,
following the expiration of existing franchises, fees will remain at their
current levels. In many markets, the incumbent local exchange carriers do not
pay such franchise fees or pay fees that are substantially less than those
required to be paid by us, although the Telecommunications Act requires that in
the future such fees be applied in a competitively neutral manner. To the extent
that, notwithstanding the Telecommunications Act, competitors do not pay the
same level of fees as us, we could be at a competitive disadvantage. Termination
of the existing franchise or license agreements prior to their expiration dates
or a failure to renew the franchise or license agreements and a requirement that
we

                                       15
<PAGE>

remove our facilities or abandon our network in place could have a material
adverse effect on us. In addition, we would be adversely affected if we are
unable to obtain additional authorization for new construction on reasonable
terms. Furthermore, open issues exist regarding the ability of new local service
providers to gain access to commercial office buildings to serve tenants.

  General.  The telecommunications market is in a period of substantial change
and uncertainty. As the Telecommunications Act and related FCC and state actions
are implemented, new issues are likely to arise that can affect our business
plan and us. No assurance can be given that future regulatory developments will
not have a materially adverse impact on us.

Employees

  As of December 31, 1999, we had over 1,600 full-time employees, none of whom
was represented by a union or covered by a collective bargaining agreement. We
believe that our relationship with our employees is good. In connection with the
construction and maintenance of our fiber optic network and the conduct of our
other business operations, we use third party contractors, some of whose
employees may be represented by unions or covered by collective bargaining
agreements.

Risk Factors

  Our business is subject to a number of risks, including the following:

We expect to continue to have operating losses and negative cash flow after
capital expenditures, which may result in our failure to meet our working
capital and debt service requirements.

  As we have implemented our business strategy to expand our telecommunications
service offerings, expand our fiber optic network and enter new markets, we have
experienced operating losses and negative cash flow after capital expenditures.
We expect this will continue during the next several years as we continue to
expand our business and make substantial capital expenditures.  In addition, we
cannot assure you that we will achieve or sustain profitability or positive net
cash flow at any time after that period.  If we cannot achieve or sustain
operating profitability and positive net cash flow, we may not be able to obtain
the funds necessary to continue our operations or to repay amounts due on our
outstanding indebtedness.

We may not have, or be able to obtain, the significant amounts of capital that
we need to expand our network, operations and services as currently planned.

  We need significant capital to expand our network, operations and services
according to our business plans.  Our current business plans require us to
continue to make significant capital expenditures in connection with the
accelerated expansion of our fiber optic network and retail services segment.
During 1999, we made capital expenditures of approximately $166 million.  We
currently estimate that our capital expenditures for our existing lines of
business will total approximately $235 million to $245 million in 2000 and our
capital expenditures for our new line of business, e/\DeltaCom, will be
approximately $65 million in 2000.  In addition, we expect to make

                                       17
<PAGE>

substantial capital expenditures after 2000, which may be even more significant
than those in previous periods. If we do not have access to the capital that we
require or if our estimates are inaccurate, we will need to change our business
plans. Such a change could have a material adverse effect on our business,
financial condition and results of operations.

  Our planned capital expenditures primarily will be for:

  .  continued development and construction of our fiber optic network,
     including transmission equipment;
  .  continued addition of facilities-based local telephone service to our
     bundle of integrated telecommunications services, including acquisition and
     installation of switches and related equipment;
  .  the addition of switching capacity, electrical equipment and additional
     collocation space in connection with the expansion of our provision of
     local telecommunications services to ISPs;
  .  market expansion; and
  .  infrastructure enhancements, principally for information systems.

  If our estimates of the capital resources available to us are not accurate for
any reason, we cannot assure you that we will be able to obtain any additional
funds on favorable terms, or at all.  Our inability to obtain such funds, if
necessary, could have a material adverse effect on our business, financial
condition and results of operations.

  The actual amount and timing of our future capital requirements may differ
substantially from our estimate due to factors such as:

  .  regulatory, technological, or competitive developments;
  .  unforeseen delays;
  .  cost overruns;
  .  changes in demand for our services; and
  .  new market developments and opportunities.

We have significant debt and may be unable to service that debt.

  We have significant debt.  Set forth below are some of our recent historical
results on a consolidated basis, adjusted to reflect our issuance of (a) $160
million principal amount of senior notes in March 1998, (b) $125 million
principal amount of senior notes in November 1998 and (c) $100 million of
convertible subordinated notes in May 1999, as if each issuance had occurred on
January 1, 1998.

  To be able to meet our debt service requirements we must successfully
implement our business strategy. Therefore, we will need to:

  .  expand our network;
  .  obtain and retain a significant number of customers; and
  .  experience significant and sustained growth in our cash flow.

  We cannot assure you that we will successfully implement our business strategy
or that we will be able to generate sufficient cash flow from operating
activities to meet our debt service obligations and working capital
requirements. Our ability to meet our obligations will be dependent upon our
future performance, which will be subject to prevailing economic conditions and
to financial, business and other factors.

Our current indebtedness contains restrictive covenants that place limits on our
business activities.

  We are subject to restrictions under the indentures pursuant to which our
publicly traded notes were issued and under our $50.0 million revolving credit
facility.  We will also be subject to additional restrictions under our planned
$160.0 million senior secured credit facility which we expect to replace our
$50.0 million revolving credit facility.

  These restrictions affect and, in certain cases, significantly limit or
prohibit, among other things, our ability and the ability of our subsidiaries to
incur additional indebtedness, create liens, make investments, issue stock, and
sell assets.  Our senior note indentures restrict our ability to incur
indebtedness, other than indebtedness to finance the acquisition of equipment,
inventory or network assets and other specified indebtedness, by requiring
compliance with specified leverage ratios. In addition, if and when we borrow
funds under our existing credit facility or our planned $160.0 million senior
secured credit facility, we will be required to maintain specified financial
ratios. We cannot assure you that we will be able to maintain the required
ratios following such borrowings.

  The amount of debt we have could adversely affect us in a number of ways,
including by:

  .  limiting our ability to obtain any necessary financing in the future for
     working capital, capital expenditures, debt service requirements or other
     purposes;
  .  limiting our flexibility in planning for, or reacting to, changes in our
     business;
  .  placing us at a competitive disadvantage relative to our competitors who
     have lower levels of debt;
  .  making us more vulnerable to a downturn in our business or the economy
     generally; and
  .  requiring us to use a substantial portion of our cash flow from operations
     to pay principal and interest on our debt, instead of contributing those
     funds to other purposes, such as working capital and capital expenditures.

We may not be able to manage our growth successfully.

  The expansion and development of our business will depend upon, among other
things, our ability to:

  .  successfully implement our sales and marketing strategy;
  .  evaluate markets;
  .  design fiber routes;
  .  secure financing;
  .  install facilities;
  .  acquire rights of way;
  .  obtain any required government authorizations;

                                       19
<PAGE>

  .  interconnect to, and collocate with, facilities owned by incumbent local
     exchange carriers; and
  .  obtain appropriately priced unbundled network elements and wholesale
     services from the incumbent local exchange carriers.

  We must accomplish these tasks in a timely manner, at reasonable cost and on
satisfactory terms and conditions. Our rapid growth, particularly in the
provision of retail services, has placed, and the growth we anticipate in our
other services may in the future also place, a significant strain on our
administrative, operational and financial resources. Our ability to continue to
manage our growth successfully will require us to enhance our operational,
management, financial and information systems and controls; and to hire and
retain qualified sales, marketing, administrative, operating and technical
personnel.  We cannot assure you that we will be able to do so. In addition, as
we increase our service offerings and expand our targeted markets, there will be
additional demands on customer support, sales and marketing, administrative
resources and network infrastructure. These demands will be intensified if we
continue to accelerate our expansion plans. Our inability to manage our growth
effectively could have a material adverse effect on our business, results of
operations and financial condition.

Development and expansion of our business, including through acquisitions, is
subject to regulatory and market risks.

  The successful implementation of our business strategy to provide an
integrated bundle of telecommunications services and expand our operations will
be subject to a variety of risks, including the following:

  .  competition and pricing;
  .  the availability of capital on favorable terms;
  .  regulatory uncertainties;
  .  operating and technical problems;
  .  the need to establish and maintain interconnection and collocation
     arrangements with incumbent local exchange carriers in our target markets;
     and
  .  the potential difficulties of offering local exchange services.

  In addition, the expansion of our business may involve acquisitions of other
telecommunications businesses and assets that, if made, could divert our
resources and management time and could require integration with our existing
operations. We cannot assure you that any acquisitions could be successfully
integrated into our operations or that any acquired business will perform as
expected. Our failure to implement our expansion and growth strategy
successfully would have a material adverse effect on our business, results of
operations and financial condition.

Our business is subject to significant competitive pressures.

  Our industry is highly competitive and the level of competition, particularly
with respect to pricing, is increasing. For example, prices for long distance
services and for data transmission services have declined substantially in
recent years. These prices are expected to continue to decline, which will
adversely affect our gross margins as a percentage of revenues. In addition,
many of our existing and potential competitors have financial, technical and
other resources and customer bases and name recognition far greater than our
own. We cannot assure you that we will be able to achieve or maintain adequate
market share or revenues, or compete effectively in any of our markets.

 . We face intense competition from incumbent local exchange carriers, especially
  BellSouth

     Local telephone and intraLATA long distance services substantially similar
     to those that we offer are also offered by the incumbent local exchange
     carriers serving the markets that we serve or plan to serve. BellSouth is
     the incumbent local exchange carrier and a particularly strong competitor
     in most of these markets. BellSouth and other incumbent local exchange

                                       20
<PAGE>

     carriers already have relationships with every customer. These carriers may
     be able to subsidize services of the type we offer from service revenues
     not subject to effective competition, which could result in even more
     intense price competition.  In addition, successful implementation of our
     business plan for provision of local telephone services is dependent on our
     ability to obtain local loop and other services and facilities from
     BellSouth.  We expect that competition from BellSouth in the provision of
     local telephone services will continue to be intense.  By impeding,
     hindering or delaying provision of services and facilities to us, BellSouth
     could inhibit or prevent us from providing local telephone service to our
     customers, which would place us at a substantial competitive disadvantage.

 . Other competitors and technologies in our industries may further increase
  competition

     Providers of long distance services and Carriers' Carrier Services. We
     ------------------------------------------------------------------
     compete with long distance carriers in the provision of interLATA long
     distance services and carriers' carrier services.  The interLATA long
     distance market consists of three major competitors, AT&T, MCI WorldCom and
     Sprint.  Other companies operate or are building networks in the southern
     United States and other geographic areas. Our other competitors in the long
     distance services and carriers' carrier services markets include or are
     likely to include RBOCs providing out-of-region and, with the future
     removal of regulatory barriers, in-region long distance services, other
     competitive local exchange carriers, microwave and satellite carriers, and
     private networks owned by large end-users. We also compete with direct
     marketers, equipment vendors and installers, and telecommunications
     management companies with respect to certain portions of our business.

     Wireless providers.  In the future, providers of wireless services may
     ------------------
     offer products that increasingly become a substitute for, rather than only
     a supplement to, a customer's wireline communications services.
     Competition with providers of wireless telecommunications services may be
     intense.  Many of our potential wireless competitors have substantially
     greater financial, technical, marketing, sales, manufacturing and
     distribution resources than our own.  In recent years, the FCC has made
     additional spectrum available through public auction for use in wireless
     communications, including broadband local loops.

     New transmission technologies.  We also may increasingly face competition
     -----------------------------
     from companies offering long distance data and voice services over the
     Internet.  Such companies could enjoy a significant cost advantage because
     at present they do not pay carrier access charges or universal service
     fees.  Other competitors are also deploying new transmission technologies
     in their networks to upgrade capacity and reduce costs as well as deploying
     other advanced networks.

     Competitive local exchange carriers.  We will face competition in the
     -----------------------------------
     markets in which we operate from one or more competitive local exchange
     carriers operating fiber optic networks, in some cases in conjunction with
     the local cable television operator.  AT&T, MCI WorldCom, Sprint and others
     have begun to offer local telecommunications services, either directly or
     in conjunction with other competitive local exchange carriers in certain
     locations, and are expected to expand that activity as opportunities
     created by the Telecommunications Act of 1996 develop.  BellSouth has
     announced plans to provide local service in areas of its region where it is
     not the incumbent local exchange carrier, and to establish its own less
     regulated "competitive local exchange carrier" subsidiaries.  In connection
     with those plans, BellSouth has proceeded to file tariffs with some state
     regulatory authorities.

 . Business combinations and strategic alliances may increase competition

  A continuing trend toward business combinations and strategic alliances in the
telecommunications industry may further increase competition. These types of
strategic alliances and business combinations could put us at a significant
competitive disadvantage.

                                       21
<PAGE>

 . Recent legislation and regulation may also increase competition

     Long distance services.  The Telecommunications Act of 1996 creates the
     ----------------------
     foundation for increased competition in the long distance market from the
     incumbent local exchange carriers. Such competition could affect the
     successful implementation of our business plans. For example, certain
     provisions of the Telecommunications Act eliminate previous prohibitions on
     the provision of both retail and carriers' carrier interLATA long distance
     services by the RBOCs, subject to compliance by such companies with
     requirements set forth in the Telecommunications Act and implemented by the
     FCC. Although the FCC has rejected several RBOC applications to provide
     interLATA services, including applications from BellSouth covering the
     states of South Carolina and Louisiana, it recently granted the application
     of Bell Atlantic to provide InterLATA service in New York, and it is
     currently considering whether to grant the application of SBC for authority
     in Texas. BellSouth is actively pursuing favorable state-level approval in
     Georgia with the goal of obtaining FCC approval in early 2000 to provide
     interLATA services in that state. BellSouth is also at various stages of
     the approval process in other states in its region, and it is possible that
     interLATA entry could be approved in one or more of those states in 2000.
     In addition, legislation is pending in Congress that, if enacted, would
     relax interLATA restriction in some respects. We could be adversely
     affected if the RBOCs, and particularly BellSouth, are allowed to provide
     wireline interLATA long distance services within their own regions before
     local competition is established.

     Broadband local services.  The FCC has proposed new rules that would give
     ------------------------
     the major incumbent local exchange carriers more freedom if they offer
     local services through separate subsidiaries. Specifically, incumbent local
     exchange carriers would be allowed to offer advanced data services through
     such subsidiaries without dominant carrier regulation and without the
     obligation to make network facilities and services of that affiliate
     available to competitors. The SEC recently approved a similar structure in
     connection with its approval of the SBC/Ameritech merger. We are evaluating
     how such actions would impact our ability to compete with BellSouth and
     other incumbent local exchange carriers. In a related development, cable
     operators are beginning to offer customers broadband access to the
     Internet. We could be adversely affected if in the future we are not able
     to offer broadband services to certain customers due to limitations on our
     ability to reach such customers over broadband local network facilities.

     Additional flexibility for incumbent local exchange carriers.  The FCC has
     ------------------------------------------------------------
     adopted new policies and rules that would grant the incumbent local
     exchange carriers additional flexibility in the pricing of interstate
     access services, and states are considering or have approved incumbent
     local exchange carrier requests for similar regulatory relief with respect
     to intrastate services. Any pricing flexibility or other significant
     deregulation of the incumbent local exchange carriers could have a material
     adverse effect on our business. To the extent the incumbent local exchange
     carriers are permitted to engage in increased volume and discount pricing
     practices prior to full competition in local services, or given other
     regulatory freedom, our results of operations and financial condition could
     be adversely affected.

     Access charges; universal service.  We also could be adversely affected by
     ---------------------------------
     FCC or state regulatory decisions affecting access charges and universal
     service. Such decisions could increase our costs of providing service or
     limit our ability to recover those costs from rates charged to customers.
     The effect on us would be particularly adverse to the extent that we bear
     a disproportionate share of these costs compared to our competitors. These
     matters are the subject of ongoing regulation, and important issues
     regarding the future of access and universal service charges remain to be
     resolved.

                                       22
<PAGE>

We face significant challenges in offering local services, including the need to
make significant investments and compete with established providers.

  We will have to continue to make significant operating and capital
investments, and address numerous operating complexities, to implement our local
telephone services strategy. Because of these and possible other unknown
factors, we cannot assure you that we will be successful in implementing our
local services strategy.  Our inability to implement this strategy could have a
material adverse affect on our business, results of operations and financial
condition.  To implement our local services strategy, we are required to:

  .  develop new products, services and systems;
  .  develop new marketing initiatives;
  .  train our sales force in connection with selling these services; and
  .  implement the necessary billing and collecting systems for these services.

  In addition, we expect to continue to face significant pricing and product
competition from the RBOCs, whose core business is providing local dial tone
service and who are currently the dominant providers of services in their
markets. We also will face significant competitive product and pricing pressures
from other incumbent local exchange carriers and from other companies like us
which attempt to compete in the local services market.

  We also expect that the addition of local service to our bundle of
telecommunications services will continue to have a negative impact on our gross
margin as a percentage of revenues. This is because the gross margin on the
resale of local services through incumbent local exchange carrier facilities is
lower than the gross margin on our other lines of business. Gross margin means
gross revenues less cost of services.

The long distance transmission industry is subject to pricing pressures and
risks of industry over-capacity.

  Since shortly after the AT&T divestiture in 1984, the long distance
transmission industry generally has experienced over-capacity and declining
prices. These trends have exerted downward pressure affecting our carriers'
carrier services and we anticipate that prices for our carriers' carrier
services will continue to decline over the next several years. Dramatic and
substantial price reductions in the long distance industry could force us to
reduce our prices significantly, which could have a material adverse effect on
our business, financial condition and results of operations.

  We expect these price declines will occur because:

  .  some long distance carriers are expanding their capacity generally;
  .  other existing long distance carriers and potential new carriers are
     constructing new fiber optic and other long distance transmission networks
     in the southern United States, and BellSouth is likely to receive authority
     to use its excess capacity to market in-region interLATA services;
  .  expansion and new construction of transmission networks is likely to create
     substantial excess capacity relative to demand in the short or medium term.
     Persons building such lines are likely to install fiber optic cable that
     provides substantially more transmission capacity than will be needed
     because the cost of the actual fiber is a relatively small portion of the
     overall cost of constructing new lines;
  .  recent technological advances may also greatly expand the capacity of
     existing and new fiber optic cable; and
  .  the marginal cost of carrying an additional call over existing fiber optic
     cable is extremely low.

  An increase in the capacity of our competitors could adversely affect our
business, even if we are also able to increase our capacity. If industry
capacity expands so much that available capacity

                                       23
<PAGE>

exceeds overall demand along any of our routes, severe additional pricing
pressure could develop. This also could have a material adverse affect on our
business, financial condition and results of operations. See "Our business is
subject to significant competitive pressures" for more information on the
competitive pressures in our industry.

The local and long distance industries are subject to significant government
regulation, and the regulations may change.

  We are required to obtain authorizations from the FCC and state public utility
commissions to offer some of our telecommunications services. We are also
required to file tariffs for many of our services and to comply with local
license or permit requirements relating to installation and operation of our
network. Any of the following could have a material adverse effect on our
business, results of operations and financial condition:

  .  failure to maintain proper federal and state tariffs;
  .  failure to maintain proper state certifications;
  .  failure to comply with federal, state or local laws and regulations;
  .  failure to obtain and maintain required licenses and permits;
  .  burdensome license or permit requirements to operate in public rights- of-
     way; and
  .  burdensome or adverse regulatory requirements or developments.

  In addition, we recently entered the newly-created competitive local
telecommunications services industry. The local telephone services market was
opened to competition through the passage of the Telecommunications Act in 1996.
Because the FCC and the states are still implementing many of the rules and
policies necessary for local telephone competition, and addressing other related
issues, it is uncertain how successful the Telecommunications Act will be in
creating local competition. If we are required to change or delay our offering
of local services as a result of changes in regulatory requirements, we may
experience adverse effects on our business, results of operations and financial
condition.

We depend on access service from incumbent local exchange carriers to provide
long distance and interexchange private services, and we could be adversely
affected if we do not benefit from reduced access charges at least as much as
our competitors.

  We depend on incumbent local exchange carriers to provide access service for
the origination and termination of our toll long distance traffic and
interexchange private lines. Historically, charges for such access service have
made up a significant percentage of the overall cost of providing long distance
service. In 1998, the FCC implemented changes to its interstate access rules
that, among other things, have reduced per-minute access charges and substituted
new per-line flat rate monthly charges. The FCC also approved reductions in
overall access rates, and established new rules to recover subsidies to support
universal service and other public policies. Additional access charge
adjustments were implemented in July 1999, and others are expected in the
future. The impact of these changes on us or our competitors is not yet clear.
We could be adversely affected if we do not experience access cost reductions
proportionally equivalent to those of our competitors. New Internet-based
competitors generally are exempt from these charges, which could give them a
significant cost advantage in this area.

If we are unable to interconnect with BellSouth and incumbent local exchange
carriers on acceptable terms, our ability to offer local telephone services will
be adversely affected.

  In August 1996, the FCC adopted rules and policies (1) implementing the local
competition provisions of the Telecommunications Act and (2) imposing
obligations on the incumbent local exchange carriers, including the RBOCs, to
enter into interconnection agreements with new competitive entrants like
ITC/\DeltaCom. We depend on our interconnection agreements with incumbent local
exchange carriers such as BellSouth, GTE, SBC and Sprint to:

                                       24
<PAGE>

  .  provide local telephone service through access to local loops, termination
     service and, in some markets, central office switches of such carriers;
  .  resell local telephone services that we obtain from the incumbent local
     exchange carriers on a wholesale basis; and
  .  obtain operational support to ensure timely delivery to us of network
     elements and wholesale services from the incumbent local exchange carriers.

  In January 1999, the U.S. Supreme Court upheld the FCC's authority to adopt
and implement these rules, but required the FCC to reconsider the list of
network elements that incumbent local exchange carriers must make available to
competitors.  In September 1999, the FCC largely reaffirmed its existing
requirements.

  Incumbent local exchange carriers meet their obligations under the
Telecommunications Act through the use of interconnection agreements negotiated
with competitive local exchange carriers under regulatory supervision. Such
agreements have been the subject of ongoing disputes, and key issues remain
open. Our ability to successfully negotiate interconnection agreements on a
timely basis and on favorable terms is critical to our ability to provide local
services on a competitive and profitable basis. We cannot assure you that we
will be able to enter into or renew interconnection agreements that permit us to
offer local services at rates that are both profitable and competitive. Any
successful effort by the incumbent local exchange carriers to deny or
substantially limit our access to their network elements or wholesale services
would have a material adverse effect on our ability to provide local telephone
services. This would have a material adverse effect on our business, results of
operations, and financial condition.

  Our interconnection agreement with BellSouth is our most significant
interconnection agreement, enabling us to provide local services in all nine
markets in which BellSouth operates. That agreement currently allows us to
provide local service on a resale basis or by purchasing all unbundled network
elements required to provide local service on a facilities basis, without having
to buy or build our own facilities. The terms of that interconnection agreement,
including interim pricing terms to which we and BellSouth have agreed, have been
approved by state regulatory authorities in all states in which BellSouth
operates. These interim pricing terms remain subject to review and modification
by such authorities. In addition, the BellSouth interconnection agreement does
not resolve all operational issues. We and BellSouth are continuing to negotiate
to resolve those issues.

  The BellSouth interconnection agreement expired on July 1, 1999. We are in
negotiations with BellSouth to renew the terms of the interconnection agreement.
In addition, we have filed for arbitration of certain unresolved issues with the
relevant state regulatory authorities in all BellSouth states, except Kentucky.
The agreement provides that the parties will continue to exchange traffic under
the current agreement after July 1, 1999 until such time as renewal terms,
conditions and prices are ordered by a state commission or negotiated by the
parties. The new terms, conditions and prices would then be effective
retroactive to July 1, 1999. We cannot assure you that we will be able to renew
the interconnection agreement with BellSouth on favorable terms, or at all.

  Under the Telecommunications Act, the RBOCs will not be permitted to provide
in-region interLATA long distance services until there is adequate competition
in the local services industry. This provides some incentive to the RBOCs to
provide access to their facilities to competitive new entrants such as
ITC/\DeltaCom. We cannot assure you, however, that once BellSouth or other RBOCs
are permitted to offer long distance service, they will continue to be willing
to enter into interconnection agreements with us that will enable us to provide
local services on competitive and profitable terms.

We are dependent upon rights of way and other third party agreements to expand
and maintain our fiber optic network.

  To construct and maintain our fiber optic network, we have obtained easements,
rights of way, franchises and licenses from various private parties, including
actual and potential competitors and local governments. We cannot assure you
that we will continue to have access to existing rights of way and franchises
after the expiration of our current agreements, or that we will obtain
additional rights necessary to extend our network on reasonable terms. In
addition, third parties may challenge our use of rights of way obtained by
others.  If a franchise, license or lease agreement were terminated and we were
forced to remove or abandon a significant portion of our network, such
termination could have a material adverse effect on our business, results of
operations, and financial condition. Similarly, our business plans could be
adversely affected if our network expansion is hindered through delays or
denials of rights of way, easements or related licenses on competitive terms.

Our inability to maintain our network infrastructure, portions of which we do
not own, could adversely affect our business, results of operations and
financial condition.

  Network agreements may be terminated.  We have effectively extended our
  ------------------------------------
network with minimal capital expenditures by entering into marketing and
management agreements with three public utility companies to sell long-haul
private line services on the fiber optic networks owned by these companies.
Under these agreements, which have remaining terms ranging from two to five
years, we generally earn a commission based upon a percentage of the gross
revenues generated by the sale of capacity on the utility's networks. We also
have an agreement to buy and sell capacity with Carolinas Fibernet, which
manages fiber optic facilities in North Carolina and South Carolina.
Cancellation or non-renewal of any of these agreements could materially
adversely affect our business, results of operations, and financial condition.

  Some of our agreements are non-exclusive. In addition, two of our three
  ----------------------------------------
agreements with the public utility companies are nonexclusive, and we may
encounter competition for capacity on the utilities' networks from other service
providers that enter into comparable arrangements with the utilities. Any
reduction in the amount of capacity that is made available to us could adversely
affect us. To the extent that we are unable to establish similar arrangements in
new markets, we may be required to make additional capital expenditures to
extend our fiber optic network.

  We may experience network equipment failures or cable cuts. Our business also
  ----------------------------------------------------------
could be materially adversely affected by a cable cut or equipment failure in
our fiber optic network. A portion of our owned and managed fiber optic network
is not protected by electronic redundancy in the event of a total cable cut.
Electronic redundancy enables us to reroute traffic to another fiber in the same
fiber sheath in the event of a partial fiber cut or electronics failure.

We are dependent on certain large customers for a significant percentage of our
revenues and we cannot assure you that we will be able to retain those
customers.

  The table below sets forth, for the years ended December 31, 1999 and 1998,
the percentage of our consolidated revenues accounted for by our two largest
carriers' carrier customers and our five largest retail services customers.

  We cannot assure you that we will be able to retain our customers. The loss
of, or a significant decrease of business from, any of our largest customers
would have a material adverse effect on our business, results of operations and
financial condition.

  For both carriers' carrier services and retail services, our customers
generally have concurrent arrangements with more than one service provider. This
enables our customers to reduce their use of our services and switch to other
providers without incurring significant expense. Our agreements with our
customers generally provide that the customer may terminate service without an
"early discontinuance charge" in the event of specified types of outages in
service and for other defined causes.  As of December 31, 1999, our carriers'
carrier business had remaining future long-term contract commitments totaling
approximately $114.2 million.  Some of those contractual commitments provide
that, if the customer is offered lower pricing with respect to any circuit by
another carrier, the customer's commitment to us will be reduced to the extent
we do not match the price for such circuit and the customer purchases such
circuit from the other carrier.

We are dependent on sophisticated billing, customer service and information
systems.

  We depend on sophisticated information and processing systems to grow, monitor
costs, bill customers, provision customer orders and achieve operating
efficiencies. As we increase our provision of dial tone and switched local
access services, the need for enhanced billing and information systems will also
increase. Our inability to identify adequately all of our information and
processing needs, or to upgrade systems as necessary, could have a material
adverse effect on our ability to reach our objectives and on our financial
condition and results of operations.

We are subject to risks associated with rapid changes in technology.

  The telecommunications industry is subject to rapid and significant changes in
technology. In addition, we may be required to select in advance one emerging
technology over another, but it will be impossible to predict with any
certainty, at the time we are required to make our investment, which technology
will prove to be the most economic, efficient or capable of attracting customer
usage. Unexpected developments, or our failure to adapt to them, could have a
material adverse effect on our business, results of operations and financial
condition.

Our success depends on our ability to attract and retain key personnel.

  Our business is currently managed by a small number of key management and
operating personnel, including our executive officers. We do not have any
employment agreements with, nor do we maintain "key man" insurance on, these
employees. The loss of the services of key personnel, or the inability to
attract, recruit and retain sufficient or additional qualified personnel, could
have a material adverse effect on our business, results of operations and
financial condition.

Our operating results could vary significantly from period to period.

  Our revenues and operating results could vary significantly from period to
period for many reasons, including:

  .  significant expenses associated with the construction and expansion of our
     network and services;
  .  competition and regulatory developments;
  .  changes in market growth rates for our products and services;
  .  availability or announcement of alternative technologies; and
  .  general economic conditions.

  These factors and any resulting fluctuations in our operating results will
make period to period comparisons of our financial condition less meaningful and
could have a material adverse effect on our business, results of operations and
financial condition.

Item 2.  Properties.

  We completed construction of our new corporate headquarters in West Point,
Georgia in April 1999.

  We own switch sites in Anniston, Birmingham and Montgomery, Alabama and lease
space for a network operations center and a switch site in Arab, Alabama. We
also lease space for our switch sites in:

  .     Jacksonville and Ocala, Florida;
  .     Atlanta, Georgia;
  .     Gulfport, Mississippi ;
  .     Greensboro, North Carolina; and
  .     Columbia, South Carolina.

The leases for these switch sites expire on various dates from 2002 to 2009.  In
addition, we have leased space in Miami, Florida and Houston, Texas, and
purchased land in Nashville, Tennessee, for switches we expect to add in 2000.

  We have also constructed a multi-service facility in Anniston, Alabama to
function as a centralized switching control center for our network and an
operator services center. In addition, we lease space to operate a Customer
Network Operations Center, or CNOC, in Atlanta, Georgia.


  We operate branch offices in:

  .       Anniston, Birmingham, Dothan, Florence, Huntsville, Mobile and
          Montgomery, Alabama;
  .       Little Rock, Arkansas;
  .       Daytona, Ft. Lauderdale, Jacksonville, Ocala, Orlando, Pensacola,
          Tallahassee and Tampa, Florida;
  .       Albany, Atlanta (two offices), Columbus and Macon, Georgia;
  .       New Orleans and Baton Rouge, Louisiana;
  .       Biloxi, Greenwood, Hattiesburg, Jackson and Tupelo, Mississippi;
  .       Charlotte, Greensboro and Raleigh, North Carolina; and
  .       Charleston, Columbia and Greenville, South Carolina;

  The leases for these offices expire on various dates from 2000 through 2005.
We also lease office space for various administrative functions, including
accounting, legal, sales and human resources in Huntsville Alabama and own an
administrative office in Arab, Alabama.

  As part of our fiber optic network and switched service system, we own or
lease rights of way, land, office space and towers throughout the southern
United States.

  We own land and microwave transmission towers at various locations in Alabama.

  We expect to lease or purchase additional office space and switching and other
network facilities in connection with the planned expansion of our
telecommunications network system.

Item 3.  Legal Proceedings.

  We are a party to legal proceedings in the ordinary course of our business,
including disputes with contractors or vendors, which we believe are not
material to our business. We also are a party to regulatory proceedings
affecting the relevant segments of the communications industry generally.


Item 4.  Submission of Matters to a Vote of Security Holders.

  There were no matters submitted to our security holders in the fourth quarter
of 1999.

</TABLE>

  On March 28, 2000, there were approximately 851 holders of record of the
common stock.

  We have never declared or paid any cash dividends on our capital stock and do
not anticipate paying cash dividends on our common stock in the foreseeable
future. It is the current policy of the Board of Directors to retain earnings to
finance the expansion of our operations. Future declaration and payment of
dividends, if any, will be determined in light of the then-current conditions,
including our earnings, operations, capital requirements, financial condition,
restrictions in financing agreements and other factors deemed relevant by the
Board of Directors.  The indentures under which we have issued our publicly
traded notes contain restrictions on our ability to pay dividends.  We expect
that the agreement for our new senior secured credit facility also will contain
such restrictions.

(d) On July 29, 1998, ITC/\DeltaCom announced a two-for-one stock split of its
    common stock to be effected in the form of a stock dividend.  The record
    date for the stock split was August 18, 1998 and the payment date was
    September 4, 1998.  The common stock began trading giving effect to the
    stock split on September 8, 1998.  All references to number of shares,
    except shares authorized, and to per share information in the consolidated
    financial statements have been adjusted to reflect the stock split on a
    retroactive basis.
(e) Pursuant to SAB 98, for periods prior to the completion of the initial

    performance or to cash flow as a measure of liquidity. EBITDA, as adjusted,
    is not necessarily comparable with similarly titled measures for other
    companies.
(g) Earnings consist of income before income taxes, plus fixed charges.  Fixed
    charges consist of interest charges and amortization of debt issuance costs
    and the portion of rent expense under operating leases representing
    interest, estimated to be one-third of such expense.  Earnings were
    insufficient to cover fixed charges for the years ended December 31, 1999,
    1998, 1997, 1996 and 1995 by $54.9 million, $32.4 million, $13.7 million,

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
of Operations.

  We have included data with respect to EBITDA, as adjusted, in the following
analysis because it is a measure commonly used in our industry.  EBITDA, as
adjusted, represents earnings before extraordinary item, net interest, other
income (expense), income taxes, and depreciation and amortization.  EBITDA, as
adjusted, is not a measure of financial performance under generally accepted
accounting principles and should not be considered an alternative to net income
as a measure of performance or to cash flow as a measure of liquidity.  EBITDA,
as adjusted, is not necessarily comparable with similarly titled measures for
other companies.

Overview

  We are a full service provider of integrated voice and data telecommunications
services on a retail basis to mid-size and major regional businesses in the
southern United States and a leading regional provider of carrier's carrier
services to other telecommunications companies.  In connection with these
businesses, we own, operate and manage an extensive fiber optic network in the
southern United States.  We had revenues of $244.8 million, $171.8 million and
$114.6 million for the years ended December 31, 1999, 1998 and 1997,
respectively.

  We provide our carriers' carrier services to other telecommunications
carriers, including, among others, AT&T, Sprint, MCI WorldCom, Qwest, Cable &
Wireless, and Broadwing.  During 1999, we extended our fiber network
approximately 450 route miles to approximately 8,250 route miles, consisting of
approximately 4,550 owned miles and approximately 3,700 managed, monitored and
marketed miles.  Our carriers' carrier services business generated revenues of
$72.9 million, $51.9 million and $31.0 million for the years ended December 31,
1999, 1998 and 1997, respectively.

  We also provide our retail services to mid-sized and major regional businesses
in the southern United States.  We offer our retail services in a bundled
package tailored to the business customer's specific needs.  These retail
services include:

  .       local exchange services;
  .       long distance services;
  .       calling card and operator services;
  .       ATM, frame relay and high capacity
          broadband private line services;
  .       Internet, intranet and Web page hosting services;
          primary rate interface connectivity and collocation services to
  .       Internet service providers;
  .       customer premise equipment sale, installation and repair;
  .       enhanced services, including conference calling, fax broadcasting and
          pre-paid calling cards;
  .       consulting, integration, operation and proactive management of data
          networks; and
  .       in-depth network performance analysis and implementation and design
          services for data network deployment.

  At December 31, 1999, we provided our retail services to approximately 12,375
business customers in 33 metropolitan areas and had sold approximately 128,200
access lines, of which approximately 101,500 had been installed.  We added
eleven branch offices, three Nortel DMS-500 voice switches, three frame relay
switches and four ATM switches to our existing network during 1999.  We intend
to provide the full range of our retail services in a total of approximately 47
metropolitan areas throughout the southern United States by the end of 2001.
Our retail services business generated revenues of $172.0 million, $119.9
million and $83.6 million for the years ended December 31, 1999, 1998 and 1997,
respectively.

  Company Background. We were incorporated in March 1997 as a wholly owned
subsidiary of ITC Holding Company, Inc., to acquire and operate ITC Holding's
retail services and carriers' carrier

                                       32
<PAGE>

services businesses. As discussed in Note 1 to our consolidated financial
statements appearing elsewhere in this report, this reorganization was accounted
for in a manner similar to a pooling of interests.

  ITC Holding began to offer carriers' carrier services in late 1992 through
Interstate FiberNet, a partnership in which ITC Holding held a 49% interest.  In
August 1994, ITC Holding acquired the remaining 51% interest in Interstate
FiberNet. Also in August 1994, ITC Holding formed a second partnership, Gulf
States FiberNet, to construct and operate a fiber optic route primarily from
Atlanta, Georgia to Shreveport, Louisiana with several supplemental spur routes.
In March 1997, ITC Holding acquired the remaining partnership interests in Gulf
States FiberNet and the Georgia Fiber Assets, which we refer to as the "Gulf
States Acquisition," which included one customer contract representing $3.5
million in annual revenues through August 2001, the expiration date of the
contract. InterQuest, which was merged into our subsidiary, Interstate FiberNet,
in July 1997, has provided operator and directory assistance services since
March 1992.  Members of our management have been managing the businesses of both
Interstate FiberNet and Gulf States FiberNet since their inception.

  In January 1996, as a result of the acquisition of DeltaCom, Inc., which we
refer to as the "DeltaCom Acquisition," we entered the retail long distance
business and acquired several fiber optic routes within Alabama that
complemented the existing networks operated by Interstate FiberNet and Gulf
States FiberNet. DeltaCom, a provider of telecommunications services since its
inception in 1982, provided long distance services to mid-sized and major
regional businesses in the southern United States.

  Carriers' Carrier Services.  We provide our carriers' carrier services using
our owned and managed fiber optic network.  This network reaches over 100 POPs
in the following ten southern states:

  .  Alabama
  .  Arkansas
  .  Florida
  .  Georgia
  .  Louisiana
  .  Mississippi
  .  North Carolina
  .  South Carolina
  .  Tennessee
  .  Texas

  Of our network's approximately 8,250 route miles, approximately 4,550 are
owned and operated by us and approximately 3,700 are owned and operated
principally by three public utilities, Duke Power Company, Florida Power & Light
Company and Entergy Technology Company, with which we have marketing and
management arrangements.  Our arrangement with Entergy is exclusive. In
addition, we have a buy-sell agreement with Carolinas FiberNet, LLC, which
manages fiber optic facilities in North Carolina and South Carolina. This
agreement enables the parties to buy and sell capacity on each other's networks
and allows us to provide customers with access to POPs throughout those states.

  In addition, as part of our strategy, we intend to continue to evaluate the
potential expansion of our network through a combination of new construction,
long-term dark fiber leases and fiber swap transactions, depending on the extent
of capital required over the economic life of the fiber assets to be deployed.
To the extent that we elect to expand our network through long-term operating
leases in lieu of construction, fiber swap transactions or long-term dark fiber
capital leases, we expect such leases to have a negative effect on EBITDA, as
adjusted; however, we expect that any expansion of our network through long-term
operating leases will provide opportunities to generate additional revenues,
which would partly offset any negative effects on EBITDA, as adjusted.  We
expect to add

                                       33
<PAGE>

approximately 1,000 to 1,500 owned and operated route miles to our fiber network
by the end of 2000 through a combination of construction and long-term dark
fiber leases on various routes.

  We derive commission revenues from the marketing, sale and management of
capacity on the utility-owned portions of our network. Negligible incremental
costs are associated with these commissions, because we use the same marketing
and sales force in servicing the utility-owned portions of the network as we do
for the portions owned by us.  Our commission revenues from these arrangements
amounted to approximately $8.4 million, $3.8 million and $1.5 million for the
years ended December 31, 1999, 1998 and 1997, respectively.  We expect
commissions associated with the utility-owned portions of the network to
continue to increase in 2000.

  We provide wholesale long-haul services to our carriers' carrier customers on
a "take or pay" long-term basis, on an individual circuit basis, or on a
month-to-month basis after the initial term of the "take or pay" or individual
circuit contract. As of December 31, 1999, we had remaining future long-term
contract commitments totaling approximately $114.2 million. These contracts
expire on various dates through 2008 and are expected to generate approximately
$103.3 million in revenues for us through 2004.

  We have implemented electronic redundancy throughout our network, which
enables traffic to be rerouted to another fiber in the same sheath in the event
of a partial fiber cut or electronic failure.  At December 31, 1999,
approximately 64% of our network was also protected by geographical diverse
routing, also called a self-healing ring, which is a network design that enables
traffic to be rerouted to an entirely different fiber optic cable, assuming
capacity is available, in the event of a total cable cut.

  Retail Services.  Our retail services involve the provision of voice, data and
video telecommunications services to end users or resellers. Our retail services
include the following:

  Local Services.  We currently provide local service by using our own
facilities and by reselling the services of incumbent local exchange carriers.
Over time, we expect to migrate a majority of the local service onto our own
facilities.  At December 31, 1999, we offered local exchange services in 32 of
the 33 markets in which we provided our retail services.  Local service revenue
comprised approximately 42% of all new retail services revenues purchased by
customers during 1999.

  In connection with offering local exchange services, we have entered into an
interconnection agreement with BellSouth to (1) resell BellSouth's local
exchange services and (2) interconnect our network with BellSouth's network for
the purpose of gaining immediate access to all of BellSouth's unbundled network
elements. This agreement allows us to enter new markets with substantially lower
capital expenditures and to offer local exchange service to our current customer
base. The BellSouth interconnection agreement currently allows us to provide
local service on a resale basis or by purchasing all unbundled network elements
required to provide local service on a facilities basis, without using our
facilities. The terms of this interconnection agreement, including interim
pricing terms agreed to by us and BellSouth, have been approved by state
regulatory authorities in all states in which BellSouth operates, although they
remain subject to review and modification by such authorities. In addition, the
BellSouth interconnection agreement does not resolve all operational issues,
which BellSouth and we are continuing to negotiate to resolve.  We believe that
this interconnection agreement provides a foundation for us to provide local
service on a reasonable commercial basis, but there can be no assurance in this
regard and important issues remain unsettled as a result of legal and regulatory
developments and related matters.

  On July 1, 1999, our resale and interconnection agreement with BellSouth
expired. We are currently in arbitration with BellSouth, in all BellSouth states
except Kentucky and Mississippi, regarding some of the terms and conditions of
the interconnection agreement. In Mississippi, we opted-in to an existing
interconnection agreement between BellSouth and another CLEC. As contemplated by
the original interconnection agreement, we will continue to exchange traffic
under substantially the same terms on a month-to-month basis until such time as
renewal terms, conditions and prices are ordered by a state commission or
negotiated by us and BellSouth. The new terms, conditions and prices would

                                       34
<PAGE>

then be retroactive to July 1, 1999. To date, orders regarding the terms and
conditions of the interconnection agreement have been issued by Florida and
South Carolina in the arbitration proceedings and we anticipate the remaining
states will issue orders by the end of the second quarter of 2000.

  Our strategy is ultimately to offer facilities-based local service in a
majority of our markets by collocating our equipment with that of BellSouth and
other incumbent local exchange carriers with which we have concluded
interconnection agreements.  We began collocating our equipment in some of the
BellSouth central office locations during the first quarter of 1998.  As of
December 31, 1999, we had completed physical collocation of switching equipment
in 125 BellSouth markets, and were offering our "Unity" product in 31 markets.
The Unity product, which we market primarily to mid-sized and major regional
businesses, utilizes a direct T-1 connection from the customer's location to one
of our switches and provides the customer with both local and long distance
calling on any of 24 available channels.  We expect to add an additional 60 to
80 collocations during 2000, bringing our total collocations to between 185 and
205.

  Under the BellSouth interconnection agreement, we continued to bill BellSouth
during 1999 for reciprocal interconnection charges related to the provision by
us of facilities-based local exchange services.  A significant amount of such
charges is attributable to call terminations by us to customers that are
Internet service providers, or ISPs.  BellSouth has stated that it views
termination to such ISPs as not included under the reciprocal charge
arrangements set forth in the interconnection agreement, and has refused to pay
compensation for such terminations either to us or to other competitive local
exchange carriers, or CLECs, operating under similar interconnection agreements.
The Alabama Public Service Commission rendered a ruling in our favor in March
1999 and issued an order requiring BellSouth to pay all withheld reciprocal
compensation sums within 20 days.  BellSouth appealed this order to the United
States District Court in Montgomery, Alabama.  In August 1999, the United States
District Court entered a decision and ordered BellSouth to pay reciprocal
compensation for dial-up calls from BellSouth customers to ISPs served by us.
BellSouth filed an appeal of the United States District Court's decision to the
11th Circuit Court of the United States regarding this issue.  The funds are
currently being held in escrow by the federal court pending outcome of
BellSouth's request for review of the public order. We have filed a similar
complaint before the South Carolina Public Utilities Commission, the Florida
Public Service Commission and the North Carolina Public Service Commission
seeking a ruling requiring BellSouth to pay the reciprocal compensation with
respect to our South Carolina, Florida and North Carolina operations. We are
reviewing all potential remedies and claims in the remaining jurisdictions.

  We have continued to bill BellSouth the reciprocal compensation rate under the
interconnection agreement which expired July 1, 1999.  We believe this rate will
be substantially reduced retroactively to July 1, 1999 pursuant to the
proceedings described above.  Such a rate reduction would result in a
substantial reduction in the related accounts receivable billed and reserved
subsequent to July 1, 1999.  For the years ended December 31, 1999 and 1998,
these charges to BellSouth amounted to approximately $23.4 million and $7.4
million, respectively, inclusive of $15.7 million of charges from July 1, 1999
to December 31, 1999.  We recognized approximately $2.0 million and $756,000 of
these charges as operating revenue during the years ended December 31, 1999 and
1998, respectively, which represent amounts BellSouth had actually paid or
indicated it will pay.  We reserved directly against the remaining $21.4 million
and $6.6 million of billings for the years ended December 31, 1999 and 1998,
respectively, inclusive of $14.6 million of billings for the period from July 1,
1999 to December 31, 1999. We believe our position with respect to the reserved
portion of the cumulative local interconnection billings is supported by the
terms of the BellSouth interconnection agreement, as do other CLECs who are
strongly contesting refusals by incumbent local exchange carriers, or ILECs, to
pay compensation in these circumstances, although, as discussed above, our
billed and reserved accounts receivable for the period from July 1, 1999 to
December 31, 1999 may be substantially reduced pending outcome of the terms of
the new interconnection agreement.  As of December 31, 1999, we had reserved for
approximately $28.0 million of cumulative local interconnection billings.

                                       35
<PAGE>

  Many regulatory authorities that have addressed the issue have ruled in favor
of CLECs, but the issue generally remains under appeal in those circumstances.
In Alabama, Florida, Georgia, North Carolina, Tennessee and Kentucky, the state
utility commissions have entered rulings favoring the arguments of the CLECs.
The issue in these states is under appeal by the ILECs.  The issue is still
pending in Louisiana.  Mississippi has issued an unfavorable ruling against
CLECs on this issue.  Although the provision of facilities-based local services
involves high fixed costs, associated variable costs are generally low.
Consequently, a resolution of the controversy with respect to payment of such
charges by BellSouth in favor of us could have a positive impact on both gross
margin and EBITDA, as adjusted.  Although discussions and arbitration hearings
have taken place between the parties since expiration of the BellSouth
interconnection agreement on July 1, 1999, there can be no assurance that the
interconnection agreement will be renewed on the same terms with respect to the
disputed charges, or at all.  Therefore, even if the controversy regarding such
charges is resolved in our favor under the current interconnection agreement,
there can be no assurance that any positive effect on our financial position
will continue beyond July 1, 1999.  The South Carolina Public Service Commission
has ruled in favor of BellSouth regarding reciprocal compensation on a going
forward basis.  We have appealed this decision. In addition, the D.C. circuit
recently vacated and remanded the FCC's ruling that, for jurisdictional
purposes, ISP bound calls are interstate.

  We expect that as we increase our provision of local service on a facilities
basis rather than on a resale basis, we will (1) reduce our own access costs
when we sell our end users long distance services, and (2) realize increased
revenues from the originating and terminating switched access services we
provide to other carriers originating and/or terminating calls for our local end
user customers.  Certain incumbent local exchange companies, including
BellSouth, have taken the position that when a carrier seeking to provide local
service obtains all necessary elements consisting of loops and switches, from
the incumbent local exchange carrier in a combined form, the incumbent local
exchange carrier retains the right to receive the access revenues associated
with service to the customers served on that basis.  Further legal challenges
are likely and important issues related to this form of interconnection remain
open, including issues related to when a competitor can obtain network elements
used for, among other things, access purposes.

  We anticipate that an increasing portion of our revenue will be derived from
local services, primarily those provided pursuant to the BellSouth
interconnection agreement and similar agreements we have with other local
exchange carriers, including GTE, Sprint and SBC Communications.  We expect that
gross margin associated with our facilities-based local retail services will be
slightly better than gross margin associated with our long distance retail
services, but that in general, gross margin associated with our retail services
will be lower than that associated with our carriers' carrier services. There
can be no assurance that we will be able to enter into additional
interconnection agreements on terms acceptable to us or at all, or that the
incumbent local exchange carriers will provide the operational support required
for us to provide local services to end users.

  Long Distance.  We offer a full range of retail long distance services,
including traditional switched and dedicated long distance, toll-free calling,
international, calling card and operator services.

  Data Services.  We provide high quality data services to our customers
primarily using frame relay switches distributed throughout our network, which
enable customers to use a single network connection to communicate with multiple
sites throughout our fiber optic network.  We currently provide ATM services on
a facilities-based and resale basis.  We will continue to seek, through
strategic business relationships with other providers, to interconnect our fiber
optic network with the fiber optic networks of other companies.  We anticipate
increased demand for data services in the future and expect that in the future a
larger percentage of our revenues will be derived from the sale of dedicated
data services.

  During 1999, we increased our data and related service offerings with the
acquisition, by merger, of AvData.  New or expanded services offerings resulting
from the acquisition include consulting, integration, operation and proactive
management of data networks with 24 x 7 monitoring, trouble

                                       36
<PAGE>

shooting, problem resolution and comprehensive network performance reporting for
corporate networks. In addition, we added in-depth network performance analysis,
as well as design and implementation services for data network deployment, to
our product mix through our acquisition of AvData. This acquisition has also
strengthened and enhanced our data service offerings.

  Internet Access, Intranet Services and Web Hosting.  We provide dedicated,
frame relay Internet access and Internet and intranet services, electronic mail,
e-commerce and Web hosting services.  We expect that mid-sized and larger
businesses will require faster Internet access and larger bandwidth in the
future, and we intend to develop and offer products and services that will
respond to that demand using our network and services.

  During 1999, we continued to expand our service offerings to the Internet
marketplace by increasing our existing service offerings to the ISP market
segment.  We offer local service to ISPs via primary rate interface
connectivity, including the collocation of ISP terminal equipment such as
modems, routers and/or network servers.  We increased our capital expenditures
related to these services significantly during 1999 and the second half of 1998
because we expect demand for these services to continue to be strong, we plan to
continue to allocate an increasing amount of capital to these services during
2000.

  Customer Premise Equipment Sale, Installation and Repair.  We sell, install
and repair customer premise equipment such as telephones, office switchboard
systems and, to a lesser extent, private branch exchange, or PBX, for customers
in the following markets:

  .  Anniston, Birmingham, Dothan, Florence, Huntsville, Mobile and
     Montgomery, Alabama;
  .  Atlanta and Columbus, Georgia;
  .  Jacksonville, Ocala and Pensacola, Florida;
  .  Baton Rouge, Louisiana;
  .  Greenwood, Hattiesburg, Jackson and Tupelo, Mississippi;
  .  Charlotte and Greensboro, North Carolina; and
  .  Charleston, Columbia and Greenville, South Carolina.

  We intend to offer customer premise equipment sales, installation and repair
in additional markets in the future, with the goals of (enhancing and supporting
our sale of local and long distance services and enhancing customer retention.
We plan to form relationships with local customer premise equipment installation
companies in all of our markets for the purpose of selling and installing
customer premise equipment not otherwise provided by us.

  Although we expect that a majority of our revenue growth will come from our
retail services business, we do not expect our retail services to obtain a
significant share of the market for telecommunications services in the southern
United States. The customer contracts for our retail services generally provide
for payment in arrears based on minutes of use for switched services and payment
in advance for private line services. The contracts generally also provide that
the customer may terminate the affected services without penalty in the event of
certain outages in service and for certain other defined causes. The contracts
also typically provide that the customer must use at least a minimum dollar
amount of switched long distance services per month for the term of the
contract. During the past several years, market prices for many
telecommunications services segments have been declining, which we believe will
likely continue. In response to these and other competitive pressures, we have
modified some of our retail contracts to extend to selected customers lower
rates over longer terms as a means of maintaining and developing our customer
base. In the future, in response to competitive considerations, we may decide to
modify other retail customer contracts in a similar manner, emphasizing lower
pricing and longer commitment periods. A substantial portion of our total
revenues is from retail long distance services. Revenue per minute from these
services has been declining and we expect it to continue to decline.

  Operating Expenses.  Our principal operating expenses consist of cost of
services, selling, operations and administration expenses, and depreciation and
amortization.

                                       37
<PAGE>

  Cost of Services.  Cost of services related to our retail services consists
primarily of access charges and local facility charges paid to local exchange
carriers, as well as wholesale carrier origination, termination and
interexchange facility charges paid to other interexchange carriers. Cost of
services related to our carriers' carrier services are substantially all fixed
costs attributable to:

  .  the leasing of dark fiber under long-term operating leases;
  .  the leasing of capacity outside our owned or managed network, referred to
     as "off-net capacity," to meet customer requirements; and
  .  network costs associated with the provision of signaling system 7, or
     "SS7," services.

  We purchase off-net capacity to provide our carriers' carrier services in
cases where we plan to construct our own network to replace the off-net portion
of particular fiber routes.  Although we are substantially able to meet the
requirements of our customers on our network, we purchase off-net capacity to
fill customers' requirements that cannot be met on our network.

  Selling, operations and administration.  Selling, operations and
administration expenses consist of expenses of selling and marketing, field
personnel engaged in direct network maintenance and monitoring, customer service
and corporate administration.

  Depreciation and amortization.  Depreciation and amortization include
depreciation of our telecommunications network and equipment and amortization of
goodwill and other intangible assets related to acquisitions, primarily the
DeltaCom Acquisition and the AvData Acquisition.

  As we continue to expand into new geographic markets, add new branch offices
and facilities, and enlarge our current product offerings, cost of services and
selling, operations and administration expenses are expected to increase
substantially. Therefore, we expect to incur increasing operating losses over
the next few years. Although we anticipate that we will generate positive cash
flow from operations, we expect that such cash flows will be more than offset by
capital expenditures during the next several years as we implement our business
plan.  We expect that our gross margins from our bundle of telecommunications
services will continue to be adversely affected by our local service product,
because the gross margin on the resale of local services through incumbent local
exchange carrier facilities will be lower than the gross margin on our existing
businesses. As we increasingly use incumbent local exchange carrier unbundled
network elements instead of resold services, we expect gross margin on local
service to improve. Such improvement is expected to result from reduced access
charges and from efficiencies realized through increased reliance on the owned
portion of our network.  Competitive market pressures to reduce prices for our
retail services, as discussed above, however, could offset improved margins that
may result from a shift away from resold local exchange services.

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

Revenues

  Total revenue increased $73.0 million (42.5%), from $171.8 million for the
year ended December 31, 1998 to $244.8 million for the year ended December 31,
1999.

  Revenues from our retail services increased $52.1 million (43.5%), from $119.9
million for the year ended December 31, 1998 to $172.0 million for the year
ended December 31, 1999. The increase in our retail services revenue was
primarily attributable to:

  .  continued geographic expansion, including the opening of eleven branch
     sales offices;
  .  maturation of existing sales offices;

                                       40
<PAGE>

  .  continued increase in the number of business customers, from approximately
     10,500 as of December 31, 1998 to approximately 12,375 as of December 31,
     1999;
  .  an increase in product diversity, including an increase in revenues from
     our local exchange services, local ISP telecommunications services and data
     related services;
  .  the inclusion of revenue from the operations of AvData and SciTel since our
     acquisition of those companies on July 8, 1999 and August 16, 1999,
     respectively;
  .  continued growth in local lines in service, from approximately 32,200 as of
     December 31, 1998 to approximately 101,500 as of December 31, 1999;
  .  continued growth in long distance minutes of use, partially offset by a
     decrease in long distance rates; and
  .  continued stability in the rate of revenue loss from lost customers from
     period to period.

  Revenues from our carriers' carrier services increased $21.0 million (40.5%),
from $51.9 million for the year ended December 31, 1998 to $72.9 million for the
year ended December 31, 1999.  The increase in revenue from our carriers'
carrier services was primarily attributable to:

  .  an increase in our customer base resulting from the continued increasing
     demand for bandwidth, partially offset by pricing pressures on some of our
     network routes;
  .  expansion of our fiber optic network, from approximately 7,800 route miles
     as of December 31, 1998 to approximately 8,250 route miles as of December
     31, 1999; and
  .  continued growth in commissions derived from our managed, monitored, and
     marketed portion of our network.

  We expect to experience continued revenue growth in both our retail services
and our carrier's carrier services into 2000.  This growth is expected to be
driven primarily by (1) increased demand for our diverse retail product mix,
especially our local and data products, (2) increased minutes of use, partially
offset by declining rates, and (3) increased demand for bandwidth, including our
new wholesale IP backbone product, partially offset by declining rates.

  No single retail services or carriers' carrier services customer represented
over 10% of our total revenues for the year ended December 31, 1999.

Cost of Services

  Total cost of services increased $35.7 million, from $83.0 million for the
year ended December 31, 1998 to $118.7 million for the year ended December 31,
1999.

  Cost of services for our retail services increased $32.6 million, from $75.3
million for the year ended December 31, 1998 to $107.9 million for the year
ended December 31, 1999. Cost of services as a percentage of revenue for our
retail services remained constant at 63% from 1998 to 1999. The increase in cost
of services in absolute dollars for our retail services was primarily
attributable to an increase in our network and other usage based provider costs
associated with our product and customer growth.  We expect to experience
improvements in the cost of services as a percentage of revenues as we continue
to move local and long distance services to our own facilities and as we receive
reductions in our off-network costs.  We expect that such improvements will
continue to be partially offset by costs related to our advanced IP and other
network initiatives.

  Cost of services for our carriers' carrier services increased $3.1 million,
from $7.7 million for the year ended December 31, 1998 to $10.8 million for the
year ended December 31, 1999. Cost of services as a percentage of revenue for
our carriers' carrier services remained constant at 15% from 1998 to 1999.  The
increase in absolute dollars was primarily attributable to an increase in our
network costs resulting from the expansion of our fiber network.  We believe the
pricing pressures we have experienced will be partially offset in the future by
an increasing demand for bandwidth, which will facilitate continued revenue
growth.

Selling, Operations and Administration Expense

  Total selling, operations and administration expense increased $32.0 million,
from $64.9 million (38% as a percentage of revenue) for the year ended December
31, 1998 to $96.9 million (40% as a percentage of revenue) for the year ended
December 31, 1999.

  Selling, operations and administration expense attributable to our retail
services increased $22.2 million, from $50.5 million (42% as a percentage of
revenue) for the year ended December 31, 1998 to $72.7 million (42% as a
percentage of revenue) for the year ended December 31, 1999.  The increase in
selling, operations and administration expense in absolute dollars for our
retail services was primarily attributable to:

  .  an increase in the number of employees, primarily employees dedicated to
     sales, customer support and provisioning;
  .  our continued geographic expansion including opening eleven branch sales
     offices; and
  .  the expansion of our product lines, especially local and data services.

  Selling, operations and administration expense attributable to our carriers'
carrier services increased $9.8 million, from $14.4 million (28% as a percentage
of revenue) for the year ended December 31, 1998 to $24.2 million (33% as a
percentage of revenue) for the year ended December 31, 1999.  The increase in
selling, operations, and administration expense for our carrier's carrier
services was primarily due to additions of personnel resulting from the
geographic expansion of our network, the infrastructure required to support the
IP backbone and an increase in information systems, research and development,
marketing and accounting costs.

Depreciation and Amortization

  Total depreciation and amortization increased $22.9 million, from $30.9
million for the year ended December 31, 1998 to $53.8 million for the year ended
December 31, 1999.  Our retail services accounted for $13.2 million of the
increase, which was primarily related to installation of new central office
equipment and other telecommunications equipment.  Our carriers' carrier
services accounted for $9.7 million of the increase, which was primarily
attributable to network expansion.  We expect depreciation and amortization to
continue to increase during 2000 as we add new switches and network facilities
and expand into new markets.

Interest Expense

  Total interest expense increased $13.4 million, from $31.9 million for the
year ended December 31, 1998 to $45.3 million for the year ended December 31,
1999.  The increase in interest expense in 1999 was primarily attributable to a
full year's interest on our 8 7/8% Senior Notes issued in March 1998, which we
refer to as the "March 1998 Notes," our 9-3/4% Senior Notes issued in November
1998, which we refer to as the "November 1998 Notes," and our 4 1/2% Convertible
Subordinated Notes due 2006, which we refer to as the "1999 Convertible
Subordinated Notes."  We expect interest expense to continue to increase during
2000 as a result of incurring interest for a full year on the outstanding notes.

Interest Income

     Total interest income increased $4.4 million, from $9.8 million for the
year ended December 31, 1998 to $14.2 million for the year ended December 31,
1999 as a result of the temporary investment of available cash balances.

Other Income (Expense)

  In March 1998, we reclassified our interest rate swap agreement from a hedge
of an anticipated transaction to a trading security resulting in a non-cash
charge against earnings of approximately

                                       42
<PAGE>

$2.5 million. This change in classification required us to record the interest
rate swap agreement on the consolidated balance sheet at fair market value at
the time of receipt of the proceeds from the offering of the March 1998 Notes.
The interest rate swap agreement is marked to market on a monthly basis. For the
year ended December 31, 1999 and 1998, we recognized income (expense) from the
mark-to-market of the interest rate swap of approximately $1.6 million and
$(2.4) million, respectively.

EBITDA, as adjusted

  EBITDA, as adjusted, increased $5.3 million, from $24.0 million for the year
ended December 31, 1998 to $29.3 million for the year ended December 31, 1999.

  EBITDA, as adjusted, attributable to our retail services for the year ended
December 31, 1999 was $(8.7) million, a decrease of $2.8 million, compared to
$(5.9) million for the year ended December 31, 1998.  EBITDA, as adjusted,
attributable to our retail services remained constant at (5)% of revenues for
the years ended December 31, 1998 and 1999.  The decrease in EBITDA, as
adjusted, in absolute dollars for our retail services was primarily attributable
to increases in:

  .  network costs associated with increased customer usage;
     costs associated with the expansion of new sales offices; and
  .  employment of additional personnel to support growth and expansion of this
     segment.

  EBITDA, as adjusted, attributable to our carriers' carrier services for the
year ended December 31, 1999 was $37.9 million, an increase of $8.0 million,
compared to $29.9 million for the year ended December 31, 1998.  The increase in
EBITDA, as adjusted, for our carriers' carrier segment was primarily
attributable to the increased demand for bandwidth, partially offset by rate
adjustments for customers to current market rates and the cost of additional
support personnel.


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

Revenues

  Total revenue increased $57.2 million (49.9%), from $114.6 million for the
year ended December 31, 1997 to $171.8 million for the year ended December 31,
1998.  Revenues from our retail services increased $36.3 million (43.4%), from
$83.6 million for the year ended December 31, 1997 to $119.9 million for the
year ended December 31, 1998. The increase in our retail services revenue was
primarily attributable to:

  .  continued geographic expansion, including the opening of seven new branch
     sales offices;
  .  the maturation of existing sales offices;
  .  continued product expansion as local exchange services and data services
     increased as a percentage of our total retail services revenue;
  .  an increase in the customer base from approximately 7,700 to approximately
     10,500;
  .  an increase in long distance minutes of use; and
  .  continued stability from period to period in the rate of revenue loss from
     lost customers.

  The majority of our retail services revenue growth during 1998 was a result of
our execution of our business plan through internal expansion efforts.  We
completed the acquisition of IT Group Communications, a Jackson, Mississippi-
based long distance carrier, in 1998.

  Revenues from our carriers' carrier services increased $20.9 million (67.4%),
from $31.0 million for the year ended December 31, 1997 to $51.9 million for the
year ended December 31, 1998.  The increase in revenue for our carriers' carrier
services was primarily attributable to continued:

  .  increases in the existing customer base as a result of increasing demand
     for bandwidth;

                                       43
<PAGE>

  .  expansion of owned and operated routes; and
  .  growth in commissions derived from our managed, monitored, and marketed
     routes.

  No single retail services or carriers' carrier services customer represented
over 10% of our total revenues for the year ended December 31, 1998.

Cost of Services

  Total cost of services increased $28.4 million, from $54.6 million for the
year ended December 31, 1997 to $83.0 million for the year ended December 31,
1998.  Cost of services for our retail services operations increased $24.7
million, from $50.6 million for the year ended December 31, 1997 to $75.3
million for the year ended December 31, 1998. Cost of services as a percentage
of revenue for our retail services operations increased from 61% in the year
ended December 31, 1997 to 63% in the year ended December 31, 1998. The increase
in cost of services as a percentage of revenue for our retail services was
primarily attributable to:

  .  a significant increase in the local service offering in 1998, mostly on a
     resale basis, which has a lower gross margin than our other services; and
  .  trunking and routing inefficiencies as we installed four new Nortel DMS-500
     switches and other telecommunications facilities in new markets.

  Cost of services for our carriers' carrier services operations increased $3.7
million, from $3.9 million for the year ended December 31, 1997 to $7.6 million
for the year ended December 31, 1998. Cost of services as a percentage of
revenue from our carriers' carrier services operations increased from 13% in the
year ended December 31, 1997 to 15% in the year ended December 31, 1998.  The
increase in the cost of services as a percentage of revenue from our carriers'
carrier services was primarily attributable to:

  .  acceptance of fibers under a long term dark fiber operating lease for a
     route from Dallas to Longview, Texas in April 1998; and
  .  pricing pressures as a result of new competitors entering our markets.

Selling, Operations and Administration Expense

  Total selling, operations and administration expense increased $26.6 million,
from $38.3 million (33% as a percentage of revenue) for the year ended December
31, 1997 to $64.9 million (38% as a percentage of revenue) for the year ended
December 31, 1998.

  Selling, operations and administration expense attributable to our retail
services increased $20.6 million, from $29.9 million (36% as a percentage of
revenue) for the year ended December 31, 1997 to $50.5 million (42% as a
percentage of revenue) for the year ended December 31, 1998.  The increase in
selling, operations and administration expense as a percentage of revenue from
our retail services was primarily attributable to:

  .  an increase in the number of employees, primarily sales, information system
     and provisioning personnel;
  .  continued geographic expansion including opening seven new branch offices;
  .  expansion of existing service offerings, primarily local services; and
  .  external costs associated with our Year 2000 readiness program, which
     amounted to approximately $1.1 million for the year ended December 31,
     1998, compared to no such external costs in the year ended December 31,
     1997.

  Selling, operations and administration expense attributable to our carriers'
carrier services increased $6.0 million, from $8.4 million (27% as a percentage
of revenue) for the year ended December 31, 1997 to $14.4 million (28% as a
percentage of revenue) for the year ended December 31, 1998.  The increase in
selling, operations, and administration expense for our carrier's carrier

                                       44
<PAGE>

services resulted from the increased cost of personnel necessitated by
geographic and service capability expansion of our network.

Depreciation and Amortization

  Total depreciation and amortization increased $12.6 million, from $18.3
million for the year ended December 31, 1997 to $30.9 million for the year ended
December 31, 1998.  Our retail services accounted for $5.4 million of the
increase, which was primarily attributable to installation of new
telecommunications equipment. Our carriers' carrier services accounted for $7.1
million of the increase, which was primarily attributable to network expansion.

Interest Expense

  Total interest expense increased $10.5 million, from $21.4 million for the
year ended December 31, 1997 to $31.9 million for the year ended December 31,
1998.  The increase in interest expense in 1998 was due to interest expense
incurred on the March 1998 Notes, the November 1998 Notes and five additional
months interest on our 11% Senior Notes due 2007 issued in June 1997, which we
refer to as the "1997 Notes."

Interest Income

  Interest income increased $5.5 million, from $4.3 million for the year ended
December 31, 1997 to $9.8 million for the year ended December 31, 1998 as a
result of short-term investment of proceeds from the March 1998 Notes and the
November 1998 Notes.

Other Expense

  In March 1998, we changed the accounting for our interest rate swap agreement
from a hedge of an anticipated transaction to a trading security, resulting in a
non-cash charge against earnings of approximately $2.5 million.  This change in
classification required us to record the interest rate swap agreement on the
consolidated balance sheet at fair market value at the time of receipt of the
proceeds from the sale of the March 1998 Notes.  The interest rate swap
agreement is marked to market on a monthly basis.  For the year ended December
31, 1998, we recognized expense of approximately $2.4 million from the mark to
market of the interest rate swap.

Income Taxes

  For the year ended December 31, 1997, we included the taxable income of ITC
Holding, our former parent, through the date of our merger with ITC Holding, in
our consolidated tax return.  As a result of tax sharing arrangements with ITC
Holding, we received benefits for certain of our net operating losses.  The
benefit received, as a percentage of taxable income, was 24% for the year ended
December 31, 1997.  During 1998, we recorded a $3.9 million receivable related
from the carry back of our 1998 net operating loss.  The benefit received, as a
percentage of taxable income, was 20% for the year ended December 31, 1998.

Extraordinary Loss

  We recorded a pre-tax loss of $10.6 million, or $8.4 million after tax,
related to the redemption on April 2, 1998 of $70 million principal amount of
the 1997 Notes.  The extraordinary loss consisted of a $7.7 million redemption
premium and a $2.9 million write-off of related debt issuance costs.

EBITDA, as adjusted

  EBITDA, as adjusted, increased $2.2 million, from $21.8 million for the year
ended December 31, 1997 to $24.0 million for the year ended December 31, 1998.
EBITDA, as adjusted, attributable to our retail services for the year ended
December 31, 1998 was $(5.9) million, a decrease of $9.0

                                       45
<PAGE>

million, compared to $3.1 million for the year ended December 31, 1997. EBITDA,
as adjusted, attributable to our retail services decreased from 4% of revenues
for the year ended December 31, 1997 to (5)% of revenues for the year ended
December 31, 1998. EBITDA, as adjusted, attributable to our carriers' carrier
services for the year ended December 31, 1998 was $29.9 million, an increase of
$11.2 million, compared to $18.7 million for the year ended December 31, 1997.


Liquidity and Capital Resources

  We (used) generated net cash from operating activities of $(5.3) million, $9.5
million, and $6.3 million for the years ended December 31, 1999, 1998 and 1997,
respectively. Changes in working capital were $(6.4) million in the year ended
December 31, 1999, $6.7 million in the year ended December 31, 1998 and $(5.0)
million in the year ended December 31, 1997.

  .  The change in the year ended December 31, 1999 was primarily due to an
     increase in accounts receivable and other current assets, partially offset
     by an increase in accounts payable, unearned revenue and accrued
     compensation and other accrued liabilities.
  .  The change in the year ended December 31, 1998 was primarily due to an
     increase in accounts payable, interest and other accruals and unearned
     revenue, partially offset by increases in accounts receivable.
  .  The change in the year ended December 31, 1997 was primarily due to
     increases in unearned revenue and accrued liabilities, offset by increases
     in accounts receivable. Of this increase in accounts receivable and
     unearned revenue, $2.3 million and $1.3 million, respectively, resulted
     from the Gulf States Acquisition, with the remaining increase in accounts
     receivable attributable to increased earned and unearned revenue in our
     carriers' carrier services and our retail services.

  Cash used for investing activities was $150.0 million, $118.2 million, and
$93.9 million for the years ended December 31, 1999, 1998 and 1997,
respectively.

  .  The cash used in the year ended December 31, 1999 was primarily for the
     funding of capital expenditures.
  .  The cash used in the year ended December 31, 1998 was primarily for the
     funding of capital expenditures.
  .  The cash used in the year ended December 31, 1997 was primarily for the
     purchase of restricted investments held by a trustee to fund the first six
     interest payments on the 1997 Notes, as required by the indenture for the
     1997 Notes, and to fund capital expenditures.

  We made capital expenditures of $165.5 million, $147.8 million, and $43.9
million for the years ended December 31, 1999, 1998 and 1997, respectively.

  .  Of the $165.5 million of capital expenditures for the year ended December
     31, 1999, $66.8 million related to our carriers' carrier services and $98.7
     million related to our retail services.
  .  Of the $147.8 million of capital expenditures for the year ended December
     31, 1998, $80.4 million related to our carriers' carrier services and $67.4
     million related to our retail services.
  .  Of the $43.9 million of capital expenditures for the year ended December
     31, 1997, $27.5 million related to our carriers' carrier services and $16.4
     million related to our retail services.

  Cash provided by financing activities was $219.6 million, $198.4 million, and
$180.6 million for the years ended December 31, 1999, 1998 and 1997,
respectively.

  .  Net cash provided by financing activities for the year ended December 31,
     1999 consisted primarily of net proceeds of $97 million from the sale of
     the 1999 Convertible Subordinated Notes, $120.9 million from the sale of
     common stock in a public offering, $2.7 million from exercise of common
     stock options, and net repayment of other long-term debt and capital leases
     of $1.1 million.

                                       46
<PAGE>

  .  Net cash provided by financing activities for the year ended December 31,
     1998 consisted primarily of net proceeds of $155.2 million from the sale of
     the March 1998 Notes, $121.4 million from the sale of the November 1998
     Notes, and $1.3 million from exercise of common stock options, less $70
     million paid in redemption of some of the 1997 Notes, a $7.7 million
     premium paid in connection with the partial redemption of the 1997 Notes,
     and net repayment of other long-term debt and capital leases of $1.6
     million.
  .  Net cash provided by financing activities for the year ended December 31,
     1997 consisted primarily of net proceeds of $192.1 million from the sale of
     the 1997 Notes and $87.6 million from our initial public offering of common
     stock, less $43.2 million of repayment of advances from ITC Holding, net
     repayments of other long-term debt and capital leases of $52.6 million and
     $3.3 million of other cash used in financing activities.

  ITC Holding partially financed the DeltaCom Acquisition and the Gulf States
Acquisition with debt, which consisted of the following:

  .  a $74.0 million term loan under a bank facility incurred in connection with
     the DeltaCom Acquisition and pushed down to us, which we refer to as "the
     DeltaCom Indebtedness";
  .  a $41.6 million bridge facility incurred in connection with the Gulf States
     Acquisition, which required the refinancing of Gulf States FiberNet's
     existing project facility; and
  .  a $10.0 million unsecured note issued in connection with the Gulf States
     Acquisition and assumed by a subsidiary of ours, which was repaid in full
     in November 1997 with a portion of the net proceeds from our initial public
     offering.

  On July 25, 1997, approximately $62.7 million of the $192.1 million of net
proceeds from the sale of the 1997 Notes was used to purchase U.S. government
securities, which are held by the 1997 Notes trustee in a pledged account to
fund the first six scheduled interest payments on the 1997 Notes. The balance of
the net proceeds from the 1997 Notes offering, approximately $129.4 million, was
released to us. A portion of the released proceeds was applied on July 25, 1997
as follows: (1) to repay approximately $57.8 million of indebtedness to ITC
Holding, including approximately $9.5 million of accrued interest associated
with the DeltaCom Acquisition and advances used by us for capital expenditures;
and (2) to repay approximately $41.6 million of indebtedness incurred under the
bridge facility, referred to above, together with approximately $200,000 of
accrued interest. In connection with our reorganization, $31.0 million of the
DeltaCom Indebtedness was forgiven by ITC Holding and contributed to us as
additional equity.

  In September 1997, Interstate FiberNet, Inc., a wholly-owned subsidiary of
ours, entered into a five-year $100 million term and revolving credit facility
to be used for working capital and other corporate purposes, including
refinancing existing indebtedness, capital expenditures and permitted
acquisitions. In February 1998, we amended the credit facility to provide, among
other things, for a $50 million revolving credit facility.  We further amended
this facility in November 1998 and May 1999.  No funds were ever dispersed under
this facility.  We recorded a loss of approximately $2.5 million due to the
reclassification of our interest rate swap agreement in connection with this
facility from a hedge of an anticipated transaction to a trading security, as a
result of our sale of the March 1998 Notes.  See Note 5 to our consolidated
financial statements appearing elsewhere in this report for further discussion
of this interest rate swap agreement.  The credit facility contains restrictions
on Interstate FiberNet and its subsidiaries and requires Interstate FiberNet to
comply with financial tests and to maintain financial ratios. The credit
facility is guaranteed by us and ITC/\DeltaCom Communications, Inc. and is
secured by a first priority lien on all current and future assets of Interstate
FiberNet and its subsidiaries and a first priority pledge of the stock of
Interstate FiberNet and its subsidiaries.

  On October 29, 1997, we completed our initial public offering in which we
issued 5,750,000 shares of common stock at a price of $16.50 per share.  After
giving effect to the two-for-one stock split we completed in the third quarter
of 1998, the initial public offering would have been 11,500,000 shares at a per
share price of $8.25.

                                       47
<PAGE>

  On March 3, 1998, we issued $160 million principal amount of the March 1998
Notes at a price of 99.9%, yielding net proceeds of approximately $155 million.
We are using the proceeds (1) to replace portions of the proceeds from our
initial public offering in October 1997, which we used in April 1998 to redeem
$70 million principal amount of the 1997 Notes, (2) to fund continued market and
fiber optic expansion and (3) to replace funds that would have otherwise been
available under our credit facility, which was modified to, among other things,
reduce available borrowings thereunder from $100 million to $50 million.

  On April 2, 1998, we redeemed $70 million principal amount of the 1997 Notes,
with proceeds remaining from the initial public offering, at a redemption price
of 111% of such principal amount, plus accrued and unpaid interest.  We recorded
an extraordinary loss of approximately $10.6 million related to the redemption
of this debt.  In connection with the redemption, the trustee for the 1997 Notes
released to us approximately $18.0 million held by the trustee as security for
the payment of remaining interest through June 1, 2000 on the 1997 Notes which
we redeemed.

  On May 20, 1998, we completed our acquisition of certain assets and
liabilities of IT Group Communications.  We issued 177,106 shares of common
stock and assumed liabilities of approximately $1.2 million to consummate the
transaction.  We acquired approximately 900 customers, predominately located in
Mississippi, and an important network point of presence in Jackson, Mississippi.

  On November 5, 1998, we issued, in a private offering, $125 million principal
amount of the November 1998 Notes, yielding net proceeds of approximately $122
million.  We intend to continue to use the net proceeds from this issuance to
fund market expansion, the on-going development and construction of our fiber
optic network, product development and general corporate purposes.

  In April 1999, we filed a registration statement with the Securities and
Exchange Commission for the issuance from time to time of up to $300 million in
equity securities, including common stock, preferred stock, shares of preferred
stock represented by depositary shares, warrants exercisable for common stock,
preferred stock or depositary shares, subscription rights evidencing the right
to purchase any of these securities and stock purchase contracts to purchase
common stock or preferred stock and stock purchase units.  The common stock we
issued and sold in May 1999, as described below, was registered pursuant to this
registration statement.

  In May 1999, we completed an underwritten public offering and sale of
6,037,500 shares of our common stock, yielding net proceeds to us of
approximately $120.9 million.  We intend to continue to use the net proceeds
from this offering (1) to fund an accelerated market expansion of our
telecommunications business, including expansion of our fiber optic network,
expansion of our local ISP telecommunications services and the opening of new
sales offices, and (2) for additional working capital and other general
corporate purposes.

  In May 1999, we completed a private offering and sale of $100 million
aggregate principal amount of the 1999 Convertible Subordinated Notes.  The 1999
Convertible Subordinated Notes bear interest at an annual rate of 4  1/2%
payable each May 15 and November 15, beginning November 15, 1999.  These notes
are unsecured general obligations of ours and are convertible into common stock
at any time after August 10, 1999, at a conversion price of $26.67 per share,
subject to adjustment in certain events.  We may redeem these notes or make the
notes nonconvertible under specified circumstances before May 17, 2002.  We
intend to continue to use the net proceeds from this issuance (1) to fund an
accelerated expansion of our fiber optic network and (2) to purchase switching
equipment, inventory, and other electronics and network assets related (a) to
our fiber optic network and (b) to our provision of primary rate interface
connectivity to ISPs.

  At December 31, 1999, we had entered into agreements with vendors to purchase
approximately $52 million of equipment and services, and, for the year ended
December 31, 1999, had made capital expenditures of $165.5 million. We currently
estimate that our aggregate capital requirements for our existing lines of
business will range from $235 million to $245 million in 2000, inclusive of the

                                       48
<PAGE>

$52 million in commitments as of December 31, 1999. We expect to make
substantial capital expenditures thereafter.  We intend to make capital
expenditures in 2000 primarily for the following:

  .  accelerated expansion of our fiber optic network in Texas, including Austin
     and San Antonio, and in Tennessee, including Memphis, Nashville,
     Chattanooga and Knoxville;
  .  continued acquisition and installation of switches and related equipment
     related to our facilities-based local telephone service offering;
  .  continued addition of switching capacity, electrical equipment and
     additional collocation space in connection with the expansion of our ISP
     local telecommunications services;
  .  market expansion; and
  .  infrastructure enhancements, principally for information systems.

  In February 2000, we received a commitment from Morgan Stanley Senior Funding,
Inc., Bank of America Securities and Goldman Sachs Credit Partners L.P. to fully
underwrite a $160 million senior secured credit facility.  This credit facility
will be subject to customary conditions for a transaction of its type, including
without limitation, completion of definitive documentation and finalization of
all terms and conditions.  We expect this credit facility to be syndicated and
fully funded in April, 2000, completely drawn at closing and not subject to
financial maintenance covenants.

  In March 2000, we launched a new business, to be operated as e/\DeltaCom, to
extend and enhance our data and Internet access products by offering customers
collocation and Web server hosting services integral to operating business-
critical applications over the Internet. We expect to invest approximately $250
million of capital to cover capital expenditures and working capital
requirements during the first three years of operations of this business,
including approximately $65 million during 2000. We expect the revenues from the
business of e/\DeltaCom to be insignificant in 2000, while resulting in negative
cash flow from operations of approximately $15 million. We will use some of the
proceeds expected to be available under our new $160 million senior secured
credit facility to fund the operations of this new business.

  The actual amount and timing of our capital requirements may differ materially
from the foregoing estimate as a result of regulatory, technological and
competitive developments, including market developments and new opportunities,
or in the event we decide to make acquisitions or enter into joint ventures and
strategic alliances in our industry.

  We may require additional capital to fund our growth, as well as to fund
continued operating losses and working capital.  We believe that cash on hand,
cash flow from operations and anticipated borrowings under the $160 million
senior secured credit facility will provide sufficient funds to enable us to
expand our business as currently planned through the second quarter of 2001,
after which we may need to seek additional financing to fund capital
expenditures and working capital.  We will review all of our alternatives for
obtaining additional equity investments.  If these or other sources of funds are
unavailable, we may not have a ready source of liquidity.  In the event that our
plans or assumptions change or prove to be inaccurate, the foregoing sources of
funds may prove to be insufficient to fund our currently planned growth and
operations.  In addition, if we make acquisitions, we may be required to seek
additional capital sooner than currently anticipated.  Additional sources may
include equity and debt financing and other financing agreements, such as vendor
financing.  There can be no assurance that we will be able to generate
sufficient cash flow from operations or that additional financing arrangements
will be available, or if available, that they can be concluded on terms
acceptable to us.  Inability to generate or obtain sufficient funds would result
in delay or abandonment of some or all of our development and expansion plans,
which could have a material adverse effect on us.

  Although our liquidity has improved, our level of indebtedness and debt
service obligations significantly increased as a result of our issuances of the
1997 Notes, the March 1998 Notes, the November 1998 Notes and the 1999
Convertible Subordinated Notes and will increase as a result of our anticipated
borrowings under our planned $160 million senior secured credit facility. The

                                       49
<PAGE>

successful implementation of our strategy, including expansion of our network
and obtaining and retaining a significant number of customers, and significant
and sustained growth in our cash flow are necessary for us to be able to meet
our debt service requirements. There can be no assurance that we will
successfully implement our strategy or that we will be able to generate
sufficient cash flow from operating activities to improve our earnings before
fixed charges, or to meet our debt service obligations and working capital
requirements. Our ability to meet our obligations will be dependent upon our
future performance, which will be subject to prevailing economic conditions and
to financial, business and other factors.

Year 2000

  We developed and implemented a comprehensive Year 2000 plan to guide us
through the evaluation, testing, remediation and implementation of all facets of
the Year 2000 transition, including among other things, the monitoring of any
potential adverse impact arising from services and equipment provided to us, by
our vendors within the telecommunications industry.  In the hours after the Year
2000 date change, our network operations and information technology teams
validated and monitored our network elements, software and hardware operations,
and the business operation processes.  To our knowledge, we experienced no
networking problems arising from the transition of our network into the year
2000.  However, we may not have identified and remediated all significant Year
2000 problems.  Further remediation efforts may involve significant time and
expense, and unremediated problems may have a material adverse effect on our
business.

  We sell our products and services to companies in a variety of industries,
each of which may be experiencing different Year 2000 issues. Customer
difficulties with Year 2000 issues might require us to devote additional
resources to resolve underlying problems.

  Although we have not been made a party to any litigation or arbitration
proceeding to date involving our products or services and related to Year 2000
compliance issues, we may in the future be required to defend our products or
services in such proceedings, or to negotiate resolutions of claims based on
Year 2000 issues.  The costs of defending and resolving Year 2000-related
disputes regardless of the merits of such disputes, and any liability for Year
2000-related damages, including consequential damages, would negatively affect
our business, results of operations, financial condition and liquidity, perhaps
materially.

  We have incurred internal labor as well as consulting and other expenses
necessary to prepare our systems for the transition into the year 2000.  Through
the end of 1999, we incurred approximately $2.1 million in external costs for
our Year 2000 program, inclusive of $1.0 million of costs incurred during the
year ended December 31, 1999.  These costs have been expensed as incurred.


Effects of New Accounting Standards

  Statement of Position 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use, provides guidance on accounting for the
costs of computer software developed or obtained for internal use.  We adopted
Statement of Position 98-1 effective January 1, 1999, with no material impact on
the consolidated financial statements.

  SFAS No. 133, Accounting for Derivative Instruments and for Hedging
Activities, establishes accounting and reporting standards requiring that every
derivative instrument, including certain derivative instruments embedded in
other contracts, be recorded in the balance sheet as either an asset or
liability measured at its fair value.  SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met.  Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that a company must formally
document, designate and assess the effectiveness of transactions that receive
hedge accounting.

                                       50
<PAGE>

SFAS No. 133 was originally effective for fiscal years beginning after June 15,
1999. SFAS No. 133 cannot be applied retroactively. SFAS No. 133 must be applied
to (1) derivative instruments and (2) certain derivative instruments embedded in
hybrid contracts that were issued, acquired, or substantively modified after
December 31, 1997. In June 1999, the FASB issued SFAS No. 137, Accounting for
Derivative Instruments and Hedging Activities - Deferral of the Effective Date
of FASB Statement No. 133, which amends SFAS No. 133 to be effective for all
fiscal years beginning after June 15, 2000 or January 1, 2001 for companies with
calendar-year fiscal years. We expect to implement SFAS No. 137 for the fiscal
year beginning January 1, 2001, and do not expect the adoption of SFAS No. 137

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To ITC/\DeltaCom, Inc.:

We have audited the accompanying consolidated balance sheets of ITC/\DELTACOM,
INC. (a Delaware corporation) AND SUBSIDIARIES as of December 31, 1999 and 1998,
and the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period ended December 31, 1999.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, the financial statements (pages F-3-F-29) referred to above
present fairly, in all material respects, the consolidated financial position of
ITC/\DeltaCom, Inc. and subsidiaries as of December 31, 1999 and 1998 and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1999 in conformity with accounting principles
generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   Organization, Basis of Presentation, and Nature of Business

 Organization

  Interstate FiberNet, Inc. (formerly ITC Transmission Systems, Inc.)
("FiberNet"), ITC Transmission Systems II, Inc. ("Transmission II"), Gulf
States Transmission Systems, Inc. ("GSTS"), and Eastern Telecom, Inc., d.b.a.
InterQuest ("InterQuest") (collectively, the "Fiber Companies"), as well as
ITC/\DeltaCom Communications, Inc. (formerly DeltaCom, Inc.), were wholly owned
subsidiaries of ITC Holding Company, Inc. ("ITC Holding"). ITC/\DeltaCom, Inc.
(the "Company") was incorporated on March 24, 1997 under the laws of the State
of Delaware, as a wholly owned subsidiary of ITC Holding, to acquire and operate
the Fiber Companies and ITC/\DeltaCom Communications, Inc. Upon receipt of
certain regulatory approvals and certain other consents on July 25, 1997, ITC
Holding completed the reorganization of such subsidiaries (the
"Reorganization") as follows:

     a. InterQuest and Transmission II were merged with and into FiberNet.

     b. ITC Holding contributed all of the outstanding capital stock of
        FiberNet, ITC/\DeltaCom Communications, Inc. and GSTS to the Company.

     c. The Company contributed all of the outstanding capital stock of
        ITC/\DeltaCom Communications, Inc. and GSTS to FiberNet.

  At December 31, 1996, FiberNet and Transmission II together held 100% of the
ownership interests in Interstate FiberNet ("Interstate"), a Georgia general
partnership. Effective with the Reorganization, Interstate was absorbed by law
into FiberNet. GSTS held a 36% ownership interest in, and was the managing
partner of, Gulf States FiberNet ("Gulf States"), a Georgia general
partnership. On March 27, 1997, ITC Holding purchased the remaining 64% interest
in Gulf States (Note 11) and contributed this interest to GSTS upon the
Reorganization.  On December 29, 1997, GSTS merged with and into FiberNet.

  Effective October 20, 1997, as part of a further reorganization of ITC
Holding, ITC Holding transferred all of its assets, other than its stock in the
Company, and all of its liabilities to another entity and then merged with and
into the Company (the "Merger"). The Company was the surviving corporation in
the Merger.

 Basis of Accounting and Financial Statement Presentation

  The accompanying consolidated financial statements are prepared on the accrual
basis of accounting. The consolidated financial statements reflect the
Reorganization and the Merger in a manner similar to a pooling of interests and
include the accounts of the Company and its wholly owned subsidiaries. All
material intercompany accounts and transactions have been eliminated in
consolidation.

  Prior to 1997, GSTS accounted for its 36% investment in Gulf States using the
equity method. To reflect the acquisition of the remaining 64% of Gulf States,
the revenues and expenses of Gulf States have been included in the accompanying
consolidated statement of operations for the year ended December 31, 1997, with
the preacquisition loss attributable to the previous owner deducted to determine
the consolidated net loss of the Company.

                                      F-9

 Nature of Business

  The Company operates in two business segments. ITC/\DeltaCom Communications,
Inc. is an integrated telecommunications service provider operating primarily in
the southern United States. ITC/\DeltaCom Communications, Inc. is engaged in the
retail sale of local exchange telephone services; long-distance telephone
services such as traditional switched and dedicated long-distance; toll-free
calling; calling card and operator services; ATM and frame relay; high-capacity
broadband private line services, as well as Internet, intranet, and Web page
hosting; and customer premise equipment sale, installation and repair.
ITC/\DeltaCom Communications, Inc. primarily serves mid-sized and major regional
businesses in the southern United States (the "Retail Services").

  The Fiber Companies are engaged in the sale of long-haul private-line services
on a wholesale basis to other telecommunications companies using their owned and
managed fiber optic network which extends throughout ten southern states
(Arkansas, Texas, Tennessee, Mississippi, Louisiana, Alabama, Georgia, North
Carolina, South Carolina, and Florida) (the "Carriers' Carrier Services").

  The Company has experienced operating losses as a result of efforts to build
its network infrastructure and internal staffing, develop its systems, and
expand into new markets. Assuming financing is available, the Company expects to
continue to focus on increasing its customer base and expanding its network
operations. Accordingly, the Company expects that its cost of services, selling,
operations, and administration expenses and capital expenditures will continue
to increase significantly, all of which will have a negative impact on short-
term operating results. In addition, the Company may change its pricing policies
to respond to a changing competitive environment.  FiberNet has obtained a five-
year, secured credit facility with Bank of America, N.A. (formerly NationsBank
of Texas, N.A.) (Note 5), and the Company has issued senior notes and equity
(Notes 5 and 7). In the opinion of management, the Company's current cash
position and available line of credit will be sufficient to meet the capital and
operating needs of the Company through at least 2000. However, there can be no
assurance that growth in the Company's revenue or customer base will continue or
that the Company will be able to achieve or sustain profitability and/or
positive cash flow.

 Sources of Supplies

  The Company voluntarily uses a single vendor for transmission equipment used
in its network. However, if this vendor were unable to meet the Company's needs,
management believes that other sources for this equipment exist on commensurate
terms and that operating results would not be adversely affected.

 Credit Risk and Significant Customers

  The Company's accounts receivable subject the Company to credit risk, as
collateral is generally not required. The Company's risk of loss is limited due
to advance billings to certain customers for services and the ability to
terminate access on delinquent accounts. The large number of customers
comprising the customer base mitigates the concentration of credit risk. In
1999, 1998 and 1997, no customer represented more than 10% of the Company's
consolidated operating revenues.

 Regulation

  The Company is subject to certain regulations and requirements of the Federal
Communications Commission and various state public service commissions.

 Reclassifications

  Certain reclassifications have been made to amounts previously reported to
conform to the current year presentation.

2.   Summary of Significant Accounting Policies

 Accounting Estimates

  The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

 Cash and Cash Equivalents

  The Company considers all short-term highly liquid investments with an
original maturity date of three months or less to be cash equivalents.

 Inventory

  Inventory consists primarily of customer premise equipment held for resale and
is valued at the lower of cost or market, using the first-in, first-out method.

 Property, Plant  and Equipment

  Property, plant and equipment are recorded at cost. Depreciation of property,
plant and equipment is provided using the composite or straight-line method over
the following estimated useful lives:

                                                                Years

 Intangible Assets

  Intangible assets include the excess of the purchase price of acquisitions
over the fair value of identifiable net assets acquired as well as various other
acquired intangibles. Intangible assets are amortized over the following

 Restricted Assets

  Restricted assets include investments in U.S. government treasury notes that
are classified as held-to-maturity and are reported at amortized costs.  These
investments represent a portion of the

                                      F-11
<PAGE>

proceeds from the Company's senior notes offering in 1997 (Note 5) that are held
by a trustee as security for and to fund the first six interest payments on
these notes.

 Other Long-Term Assets

  Other long-term assets primarily include debt issuance costs that are
amortized using the effective interest rate method over the life of the related
debt.

 Long-Lived Assets

  The Company reviews its long-lived assets, such as property, plant and
equipment and intangible assets, for impairment at each balance sheet date or
whenever events or changes in circumstances indicate that the carrying amount of
an asset should be assessed. Management evaluates the intangible assets related
to each acquisition individually to determine whether impairment has occurred.
Management believes its long-lived assets in the accompanying balance sheet are
appropriately valued.

 Unearned Revenue

  Unearned revenue represents the liability for advance billings to customers
for use of the Company's fiber-optic network. Customers are billed in advance
for fixed monthly charges.

 Unbilled Revenue

  ITC/\DeltaCom Communications, Inc. records unbilled revenue for long-distance
services provided to customers but not yet billed. Approximately $7.3 million
and $4.9 million in unbilled revenue are included in accounts receivable in the
accompanying consolidated balance sheets at December 31, 1999 and 1998,
respectively.

 Income Taxes

  The Company utilizes the liability method of accounting for income taxes.
Under the liability method, deferred taxes are determined based on the
difference between the financial and tax bases of assets and liabilities using
enacted tax rates in effect in the years in which the differences are expected
to reverse.

  The Internal Revenue Code and applicable state statutes provide that the
income and expenses of a partnership are not separately taxable to the
partnership but rather accrue directly to the partners. Accordingly, the
accompanying financial statements include provisions for federal and state
income taxes related to partnership interests in Interstate and Gulf States held
by FiberNet, Transmission II, and GSTS prior to the Reorganization.

  The Company was included in the consolidated federal income tax return of ITC
Holding through 1996.  Under a tax-sharing arrangement with ITC Holding, prior
to the Merger the Company was paid for the utilization of net operating losses
included in the consolidated tax return, even if such losses could not have been
used if the Company were to have filed on a separate return basis.  As a result
of the Merger (Note 1), ITC Holding's consolidated results of operations through
October 20, 1997 were included in the Company's 1997 consolidated federal income
tax return. The Company and its subsidiaries file separate state income tax
returns.

 Revenue Recognition

  Revenues are recognized as services are provided and consist primarily of
charges for use of telecommunications services and for use of the Company's
fiber-optic network.

a price of 99.9% (the "March 1998 Notes") for an effective yield of 8.88%.
Interest is payable semiannually on March 1 and September 1.  On November 5,
1998, the Company completed the issuance of $125 million principal amount of 9
3/4% Senior Notes due 2008 (the "November 1998 Notes").  Interest is payable
semiannually on May 15 and November 15.  On May 12, 1999, the Company completed
the issuance of $100 million principal amount of 4  1/2% Convertible
Subordinated Notes due 2006 (the "1999 Notes").  Interest is payable
semiannually on May 15 and November 15.

  Proceeds from the 1997 Notes were held by the trustee until all regulatory
approvals related to the Reorganization described in Note 1 were received.  Upon
their release, a portion of the proceeds was used to repay approximately $48
million of the Company's advances from ITC Holding and approximately $41.6
million under the GSTS Bridge Facility discussed below, as well as accrued
interest.  At December 31, 1999, approximately $6.7 million of such proceeds are
held by the trustee as security for, and to fund, the next payment on these
notes due on June 1, 2000.

  On April 2, 1998, the Company used proceeds from its initial public offering
of common stock to redeem $70 million principal amount of its 1997 Notes at a
redemption price of 111% of the principal amount thereof, plus accrued and
unpaid interest.  In conjunction with this redemption, the Company recorded a
pre-tax extraordinary loss of $10.6 million (approximately $8.4 million after
tax), consisting of a $7.7 million redemption premium and a $2.9 million write
off of debt issuance costs.

  The 1997 Notes, the March 1998 Notes, and the November 1998 Notes
(collectively the "Senior Notes") are general, unsubordinated and unsecured
senior obligations of the Company.  The Company's subsidiaries have no
obligation to pay amounts due on the Senior Notes and do not

                                      F-15
<PAGE>

guarantee the Senior Notes. Therefore, the Senior Notes are effectively
subordinated to all liabilities of ITC/\DeltaCom's subsidiaries, including trade
payables. Any rights of the Company and its creditors, including holders of the
Senior Notes, to participate in the assets of any subsidiary of the Company upon
any liquidation or reorganization of any such subsidiaries will be subject to
the prior claims of that subsidiary's creditors. The Senior Notes are subject to
certain covenants that, among other things, restrict the ability of
ITC/\DeltaCom and its subsidiaries to incur additional indebtedness, pay
dividends or make distributions.

  The 1999 Notes are unsecured general obligations of the Company, and are
convertible into common stock any time after August 10, 1999, at a conversion
price of $26.67 per share, subject to adjustment in certain events.
ITC/\DeltaCom may redeem the notes or make the notes nonconvertible under
certain circumstances before May 17, 2002.

 GSTS Bridge Facility

  In connection with the acquisition of the remaining 64% interest in Gulf
States in March 1997 (Note 11), GSTS refinanced Gulf States' outstanding
indebtedness of approximately $41.6 million with a bridge facility (the "GSTS
Bridge Facility").  In connection with the refinancing, GSTS wrote off $819,000
($508,000 net of tax benefits) in unamortized debt issuance costs, which is
reflected in the accompanying statement of operations as an extraordinary loss
on early extinguishment of debt. The GSTS Bridge Facility, which bore interest
at LIBOR plus 2.25%, matured on the date the proceeds from the Company's
offering of the 1997 Notes were released (July 25, 1997).

  GSTS did not retire a forward starting interest rate swap agreement (the
"Swap"), which swapped the variable interest rate with a fixed rate of 8.25%,
held by Gulf States in connection with this refinancing. At December 31, 1999,
the Swap had a notional amount of approximately $23.8 million.  At December 31,
1999, the Company would be required to pay approximately $751,000 to terminate
the Swap.  The Company made payments totaling approximately $851,000, $898,000
and $990,000 during 1999, 1998 and 1997, respectively, in connection with the
Swap, which are included in other income (expense) in the accompanying
consolidated statements of operations.  While borrowings were outstanding under
the GSTS Bridge Facility, the Swap was accounted for as a hedge.  The Company
planned to continue accounting for this agreement as a hedge of an anticipated
transaction, in connection with planned borrowings under the Credit Agreement,
as defined below. The interest rate swap agreement expires in December 2002.

  Upon receipt of the proceeds from the March 1998 Notes, the Company ceased
accounting for the Swap as a hedge of an anticipated transaction and began
accounting for the Swap as a trading security.  The Swap is marked to market at
each balance sheet date and the related gain (loss) is included in other income
(expense).  For the year ended December 31, 1999, the Company recorded
approximately $754,000 in other income related to the Swap agreement. For the
year ended December 31, 1998, the Company recorded approximately $3.3 million in
other expense related to the Swap.

 Credit Agreement

  On September 17, 1997, FiberNet entered into a credit agreement with Bank of
America, N.A., as administrative lender, and certain other lenders (the "Credit
Agreement"). The Credit Agreement originally provided for a term and revolving
credit facility of up to $100 million to be used for working capital and other
purposes, including refinancing existing indebtedness, capital expenditures, and
permitted acquisitions. The Credit Agreement matures on September 15, 2002 and
included a $50 million multidraw term loan facility and a $50 million revolving
credit facility allowing for amounts to be drawn under the term loan facility
until September 15, 1999. All $50 million of the term loan facility was required
to be utilized before any amount over $10 million could

                                      F-16
<PAGE>

be drawn down under the revolving credit facility. Amounts drawn under the
Credit Agreement will bear interest, at FiberNet's option, at either the Base
Rate or LIBOR, plus an applicable margin.

  In connection with the 1999 Notes offering, the Company amended its secured
revolving credit facility with Bank of America, N.A., to permit (1) the merger
with AvData Systems, Inc. (see Note 11), (2) the issuance of the common stock in
the May 1999 common stock offering (see Note 7) and (3) the issuance of and
payment of interest on the 1999 Notes, the redemption of the 1999 Notes and the
issuance of common stock upon conversion of the 1999 Notes.

  Borrowings under the Credit Agreement are guaranteed by the Company and are
secured by a first priority lien on substantially all current and future assets
and properties of FiberNet and its subsidiaries and a first priority pledge of
the stock of FiberNet and its subsidiaries.  No amounts were outstanding under
the Credit Agreement at December 31, 1999 or 1998.  The Credit Agreement
contains covenants limiting the Company's ability to incur debt or make
guaranties, create liens, pay dividends, make distributions or stock
repurchases, make investments or capital expenditures, issue capital stock,
engage in transactions with affiliates, sell assets, and engage in mergers and
acquisitions. The Credit Agreement also requires the Company to comply with
certain financial tests and to maintain certain financial ratios on a
consolidated basis.

  During 1998, the Company recorded a receivable for federal income taxes of
approximately $3.9 million in connection with the carry back of a portion of its
1998 federal net operating loss. At December 31, 1999, the Company had federal
and state net operating loss carryforwards of approximately $128.0 million and
$167.8 million, respectively.  The carryforwards expire primarily in 2018 and
2019.  As the Company is unable to conclude that it is more likely than not that
it will be able to realize the benefit of its deferred tax assets, it has
provided a 100% valuation allowance against the net amount of such assets at
December 31, 1999.  In addition to the $4.3 million increase in the 1998
valuation allowance recorded within the income tax provision, approximately $1.9
million of the 1998 valuation allowance increase was allocated to the
extraordinary item (Note 5).  Also, the Company realized the benefit of non-
qualified stock compensation expense for tax purposes in excess of stock
compensation expense for book purposes of approximately $2.7 million and $2.1
million for the years ended December 31, 1999 and 1998, respectively.  This
amount has been credited directly against additional paid-in capital, net of a
full valuation allowance.  The net deferred tax liabilities at December 31, 1999
of $512,000 represent certain net state deferred tax liabilities.

  Section 382 of the Internal Revenue Code of 1986, as amended, limits the
utilization of net operating loss carryforwards when there are changes in
ownership greater than 50%, as defined.  If such a change occurs, the timing of
the Company's utilization of its U.S. net operating loss carryforwards could be
affected.

income tax rate for the periods presented is as follows:

7.   Equity Interests

 Merger With ITC Holding

  In connection with the Merger (Note 1), holders of ITC Holding's common stock
and convertible preferred stock received 4.59045 shares of the Company's common
stock and Series A convertible preferred stock. Fractional shares were paid in
cash.

 Initial Public Offering

  During October 1997, the Company completed the sale of 11,500,000 shares of
its common stock to the public at an offering price of $8.25 a share.  The
proceeds of the offering, net of offering expenses, were $87.7 million.

 Stock Split

  On July 29, 1998, the Company announced a two-for-one stock split of its
common stock to be effected in the form of a stock dividend (the "Stock Split").
The record date for the Stock Split was August 18, 1998 and the payment date was
September 4, 1998.  The common stock began trading giving effect to the Stock
Split on September 8, 1998.  All references to number of shares, except

                                      F-18
<PAGE>

shares authorized, and to per share information in the consolidated financial
statements have been adjusted to reflect the Stock Split on a retroactive basis.

 Registration Statement

  In April 1999, the Company filed a registration statement with the Securities
and Exchange Commission for the issuance from time to time of up to $300 million
in equity securities, including common stock, preferred stock, shares of
preferred stock represented by depositary shares, warrants exercisable for
common stock, preferred stock or depositary shares, subscription rights
evidencing the right to purchase any of these securities and stock purchase
contracts to purchase common stock or preferred stock and stock purchase units.

 Common Stock Offering

   In May 1999, the Company completed an underwritten public offering and sale
of 6,037,500 shares of its common stock to the public, yielding net proceeds to
the Company of approximately $120.9 million.

 Employee Stock Option Plan

  Upon the Reorganization, all employees of the Company became eligible to
receive stock options under the Company's 1997 Stock Option Plan, as amended
(the "Stock Option Plan"), which was adopted by the Company and approved by
ITC Holding on March 24, 1997.

  The Stock Option Plan provides for the grant of options that are intended to
qualify as "incentive stock options" under Section 422 of the Code to
employees of the Company, its subsidiaries, and ITC Holding, as well as the
grant of non-qualifying options to any other individual whose participation in
the Stock Option Plan is determined to be in the best interests of the Company.
The Stock Option Plan authorizes the issuance of up to 4,815,000 shares of the
Company's common stock pursuant to options granted under the Stock Option Plan
(subject to antidilution adjustments in the event of a stock split,
recapitalization, or similar transaction). On May 13, 1999, the Company's
stockholders approved an increase in the number of options authorized to be
granted under the 1997 Stock Option Plan from 4,815,000 to 7,815,000.  The
maximum number of shares subject to options that can be awarded under the Stock
Option Plan to any person is 1,605,000 shares. The compensation committee of the
Company's board of directors will administer the Stock Option Plan and will
grant options to purchase common stock.

  The option exercise price for incentive stock options granted under the Stock
Option Plan may not be less than 100% of the fair market value of the common
stock on the date of grant of the option (or 110% in the case of an incentive
stock option granted to an optionee beneficially owning more than 10% of the
outstanding common stock). The option exercise price for non-incentive stock
options granted under the Stock Option Plan may not be less than the par value
of the common stock on the date of grant of the option. The maximum option term
is 10 years (or five years in the case of an incentive stock option granted to
an optionee beneficially owning more than 10% of the outstanding common stock).
There is also a $100,000 limit on the value of common stock (determined at the
time of grant) covered by incentive stock options that become exercisable by an
optionee in any year. Options granted will become exercisable with respect to
50% of the shares subject to the options on the second anniversary of the date
of grant and with respect to 25% of the shares subject to the options on each of
the third and fourth anniversaries of the date of grant.

  The Company's board of directors may amend or terminate the Stock Option Plan
with respect to shares of common stock as to which options have not been
granted.

                                      F-19
<PAGE>

  On March 24, 1997 and July 29, 1997, the Company granted options to purchase
2,532,690 shares and 337,866 shares, respectively, of common stock under the
Stock Option Plan. All options were granted at a price at least equal to the
estimated fair value of the common stock on the date of grant ($2.25) as
determined by the Company's board of directors based on equity transactions and
other analyses. Options to purchase an additional 96,502 shares of common stock
at $2.25 per share were granted on October 1, 1997. At December 31, 1999 and
1998, unamortized compensation expense of $266,000 and $410,000, respectively,
is recorded as an offset to equity in the accompanying balance sheet related to
the options granted October 1, 1997, since the price of the options was below
fair market value.  Compensation expense is recognized over the vesting period.

  Following the Company's initial public offering, options to purchase an
additional 123,830 shares of common stock at $8.63 per share were granted on
October 28, 1997. The $8.63 per share represents the closing sale price of the
Company's stock on the date of grant.

 Director Stock Option Plan

  On March 24, 1997, the Company adopted and its stockholders approved the
Director Stock Option Plan (the "Director Plan"). The Director Plan provides
for the "formula" grant of options that are not intended to qualify as
"incentive stock options" under Section 422 of the Code to directors of the
Company who are not officers or employees of the Company or ITC Holding, (each
an "Eligible Director"). The Director Plan authorizes the issuance of up to
481,500 shares of common stock pursuant to options granted under the Director
Plan (subject to antidilution adjustments in the event of a stock split,
recapitalization, or similar transaction). The option exercise price for options
granted under the Director Plan will be at least 100% of the fair market value
of the shares of common stock on the date of grant of the option. Under the
Director Plan, each Eligible Director will be granted an option to purchase
32,100 shares of common stock upon such person's initial election or appointment
to serve as director. Options granted will become exercisable with respect to
50% of the shares subject to the options on the second anniversary of the date
of grant and with respect to 25% of the shares subject to the options on each of
the third and fourth anniversaries of the date of grant. The options will expire
ten years and 30 days after the date of grant.

  On March 24, 1997, the Company granted options to purchase 32,100 shares of
its common stock to each of its six non-employee directors. All options were
granted at a price equal to the estimated fair value of the common stock on the
date of grant ($2.25) as determined by the Company's board of directors based on
equity transactions and other analyses.

 ITC Holding Stock Option Plan

  Prior to the Merger, ITC Holding sponsored a stock option plan which provided
for the granting of stock options to substantially all employees of  ITC Holding
and its wholly owned and majority owned subsidiaries, including the Company.
Options were generally granted at a price (established by ITC Holding's board of
directors based on equity transactions and other analyses) equal to at least
100% of the fair market value of ITC Holding's common stock on the option grant
date. Options granted generally became exercisable 40% after two years and 20%
per annum for the next three years and remained exercisable for ten years after
the option grant date. At December 31, 1996, employees of the Company held
outstanding options for a total of 314,768 of ITC Holding's shares at option
prices ranging from $7.60 to $30.50 per share. In connection with the Merger and
the related spin-off of ITC Holding's other subsidiaries, stock options
outstanding under ITC Holding's stock option plan were adjusted.  Each ITC
Holding option holder received an option in the spin-off entity and 4.59045
options in the Company (the "Replacement Options").  All Replacement Options
were at exercise prices that preserved the economic benefit of the ITC Holding
options at the spin-off and merger date.  As a result, options for 7,080,176
shares of the Company's Common Stock were issued under the Stock Option Plan at
exercise prices ranging from $0.16 per share to $4.44 per share.

 Statement of Financial Accounting Standards (SFAS) No. 123

  The Company accounts for its stock based compensation plans under Accounting
Principles Board Opinion No. 25, under which no compensation cost is recognized
for options granted with an exercise price equal to the fair market value of the
Company's common stock at the grant date. The Company has computed, for pro
forma disclosure purposes, the value of all options for shares of common stock
granted to employees of the Company using the Black-Scholes option pricing model
and the following weighted average assumptions:

</TABLE>

  The weighted average fair value of options and Replacement Options granted to
employees of the Company in 1999, 1998 and 1997 was $19.19, $13.48 and $7.34 per
share, respectively. The total value of options and Replacement Options for
common stock granted to employees of the Company during 1999, 1998 and 1997 was
computed as approximately $35.4 million, $16.2 million and $14.2 million
(including approximately $7.7 million related to the Replacement Options in
1997), respectively, which would be amortized on a pro forma basis over the
four-year vesting period of the options (five-year vesting period as to the
Replacement Options). If the Company had accounted for these plans in accordance
with SFAS No. 123, Accounting for Stock Based Compensation, the Company's net
loss for the years ended December 31, 1999, 1998 and 1997 would have increased
as follows:

8.  Commitments and Contingencies

 Purchase Commitments

  At December 31, 1999 the Company had entered into agreements with vendors to
purchase approximately $52 million of equipment related to the improvement and
installation of switches, other network expansion efforts and certain services,
the majority of which is expected to be purchased in 2000.

                                      F-22
<PAGE>

 Legal Proceedings

  In the normal course of business, the Company is subject to various
litigation; however, in management's opinion and the opinion of counsel, there
are no legal proceedings pending against the Company that would have a material
adverse effect on the financial position, results of operations, or liquidity of
the Company.

  Reciprocal Interconnection Charges

  In connection with offering local exchange services, the Company entered into
a resale and interconnection agreement (the "Interconnection Agreement") with
BellSouth Corporation ("BellSouth") effective July 1, 1997.  On July 1, 1999,
the Company's Interconnection Agreement with BellSouth expired.  The Company is
currently in arbitration with BellSouth, in all BellSouth states except
Kentucky, regarding certain terms and conditions of the Interconnection
Agreement.  As contemplated by the original Interconnection Agreement, the
parties will continue to exchange traffic under substantially the same terms on
a month-to-month basis until such time as renewal terms, conditions and prices
are ordered by a state commission or negotiated by the parties.  The new terms,
conditions and prices would then be retroactive to July 1, 1999.  To date,
orders regarding the terms and conditions of the Interconnection Agreement have
been issued by Florida and South Carolina in the arbitration proceedings, and
the Company anticipates the remaining states' orders to be issued by the end of
the second quarter of 2000.  The Company is reviewing all potential remedies and
claims in remaining jurisdictions.

  Pursuant to the Interconnection Agreement, the Company continued to bill
BellSouth during 1999 for reciprocal interconnection charges related to the
provision of facilities-based local exchange services.  A significant amount of
these charges is attributable to call terminations by the Company to customers
that are Internet service providers, "ISPs".  BellSouth has stated that it views
termination to ISPs as not included under the reciprocal charge arrangements set
forth in the Interconnection Agreement, and has refused to pay compensation for
such terminations either to the Company or to other competitive local exchange
carriers, or CLECs, operating under similar interconnection agreements.  The
Alabama Public Service Commission rendered a ruling in favor of ITC/\DeltaCom in
March 1999 and issued an order requiring BellSouth to pay all withheld
reciprocal compensation sums within 20 days.  BellSouth appealed this ruling to
the United States District Court in Montgomery, Alabama.  In August 1999, the
United States District Court entered a decision and ordered BellSouth to pay
reciprocal compensation for dial-up calls from BellSouth customers to ISPs
served by the Company.  BellSouth filed an appeal of the United States District
Court's decision to the 11th Circuit Court of the United Sates regarding this
issue.  The funds are currently being held in escrow by the federal court
pending outcome of BellSouth's request for review of the order by the United
States District Court. The Company has filed a similar complaint before the
South Carolina Public Utilities Commission and the Florida Public Service
Commission seeking a ruling requiring BellSouth to pay the reciprocal
compensation with respect to South Carolina and Florida operations.

  The Company has continued to bill BellSouth the reciprocal compensation rate
under the Interconnection Agreement which expired July 1, 1999, which rate the
Company believes will be substantially reduced retroactively to July 1, 1999
pursuant to the proceedings described above.  Such a rate reduction would result
in a substantial reduction in the related accounts receivable billed and
reserved subsequent to July 1, 1999.  For the years ended December 31, 1999 and
1998, these charges to BellSouth amounted to approximately $23.4 and $7.4
million, respectively, inclusive of $15.7 million of charges from July 1, 1999
to December 31, 1999.  The Company recognized approximately $2.0 million and
$756,000 of these charges as operating revenue during the years ended December
31, 1999 and 1998, respectively, which represent amounts BellSouth had actually
paid or indicated it will pay.  The Company reserved directly against the
remaining $21.4 million

                                      F-23
<PAGE>

and $6.6 million of billings for the years ended December 31, 1999 and 1998,
respectively, inclusive of $14.6 million of billings for the period from July 1,
1999 to December 31, 1999. As of December 31, 1999, the Company had reserved for
approximately $28.0 million of cumulative local interconnection billings.


9.   Employee Benefit Plans

  Employees of the Fiber Companies participated in ITC Holding's 401(k) defined
contribution plan until the Merger. This plan covered all employees of the
participating entities who had one year of service and were at least 18 years of
age. ITC Holding contributed a discretionary amount of the employees' earnings
based on the plan's earnings. No discretionary contributions were made for 1997.
In addition, the Fiber Companies offer a partial matching of employee
contributions at a rate of 1/2% for each 1% of the employee earnings contributed
to a maximum match of 4% of employee earnings. Total matching contributions made
to the plan and charged to expense for the year ended December 31, 1997 were
$84,000.

  Employees of ITC/\DeltaCom Communications, Inc. participated in a separately
administered 401(k) defined contribution plan. The plan covered substantially
all ITC/\DeltaCom Communications, Inc. employees with at least one year of
service. Participants may elect to defer 15% of compensation up to a maximum
amount determined annually pursuant to Internal Revenue Service regulations.
ITC/\DeltaCom Communications, Inc. has elected to provide matching employer
contributions equal to the lesser of 3% of compensation or the maximum amount
annually for each participant. ITC/\DeltaCom Communications, Inc.'s policy is to
fund contributions as earned. Company contributions made to the plan and charged
to expense for the year ended December 31, 1997 were $199,000.

  Following the Merger, ITC Holding's 401(k) defined contribution plan became
the Company's plan. Effective January 1, 1998, the ITC/\DeltaCom Communications,
Inc. 401(k) plan was merged into the Company's plan. The Company offers matching

Acquisition of Gulf States

  On March 27, 1997, ITC Holding purchased the remaining 64% interest in Gulf
States not previously owned, along with certain other fiber and fiber-related
assets, including a significant long-term customer contract (the "Georgia Fiber
Assets") for $27.9 million, plus contingent consideration valued at $3.7
million.  The purchase price included 588,411 shares of ITC Holding's Series A
convertible preferred stock valued at approximately $17.9 million and an
unsecured purchase money note for $10.0 million.  The initial purchase price was
allocated: $17.0 million to the 64% interest in Gulf States and $10.9 million to
the Georgia Fiber Assets. The note, bearing interest at 11%, was payable in ten
semi annual principal payments of approximately $1 million plus accrued
interest, beginning September 30, 1997.  The contingent consideration was due no
later than April 30, 1998, at which time the Company was obligated to deliver
additional preferred stock equal to 35.7% of 64%, multiplied by six, multiplied
by the amount, if any, by which the earnings before interest, taxes,
depreciation, and amortization of Gulf States for the year ended December 31,
1997 exceed $11.3 million.  In October 1997, ITC Holding issued 56,742 shares of
its Series A convertible preferred stock in connection with this earn-out
provision. In connection with the Merger, these shares were converted into
130,236 shares of the Company's Series A convertible preferred stock valued at

13.  Quarterly Financial Data (Unaudited)

  The following table has been prepared from the financial records of the
Company, without audit, and reflects all adjustments that are, in the opinion of
management, necessary for a fair presentation of the results of operations for
the interim periods presented (in thousands, except per share amounts).  The sum
of the per share amounts do not equal the annual amounts because of the changes
in the weighted-average number of shares outstanding during the year.

14.  Subsequent Events (Unaudited)

  The Company expects to close Senior Secured Credit Facilities totaling $160
million in April, 2000, including a $100 million Tranche 1 Term Loan B facility
to be used to finance working capital, capital expenditures, and other general
corporate purposes, and a $60 million Tranche 2 Term Loan B facility to be used
to finance the purchase of telecommunications equipment. The $100 million
Tranche 1 Term Loan B facility will be secured by all the Company's assets,
except for the telecommunications equipment purchased with proceeds from the
Tranche 2 Term Loan B facility. These credit facilities will be senior to the
$415 million principal amount of outstanding senior notes and $100 million
principal amount of convertible subordinated notes. Final maturity of the
facilities is expected to be 7 1/2 years after closing. The Company expects
these credit facilities to replace the credit facility entered into in September
1997 with Bank of America, N.A. (Note 5).

  In March 2000, the Company launched a new business to be operated as
e/\DeltaCom, to extend and enhance the Company's data and Internet access
products by offering customers collocation and Web server hosting services
integral to operating business-critical applications over the Internet.
