       THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M.,
               NEW YORK CITY TIME, ON    , 1997, UNLESS EXTENDED.
 
  ITC/\DeltaCom, Inc. (the "Company") hereby offers, upon the terms and subject
to the conditions set forth in this Prospectus (as the same may be amended or
supplemented from time to time) and in the accompanying Letter of Transmittal
(the "Letter of Transmittal") (which together constitute the "Exchange Offer"),
to exchange $1,000 principal amount of its 11% Senior Notes due June 1, 2007
(the "Exchange Notes") which have been registered under the Securities Act of
1933, as amended (the "Securities Act"), for each $1,000 principal amount of
its outstanding unregistered 11% Senior Notes due June 1, 2007, of which $200
million in aggregate principal amount is outstanding as of the date hereof (the
"Senior Notes" and, together with the Exchange Notes, the "Notes").
 
  The form and terms of the Exchange Notes will be identical in all material
respects to the form and terms of the Senior Notes, except that (i) the
Exchange Notes will have been registered under the Securities Act and therefore
will not be subject to certain restrictions on transfer applicable to the
Senior Notes and (ii) holders of the Exchange Notes will not be entitled to
certain rights of holders of the Senior Notes under the Registration Rights
Agreement dated June 3, 1997 (the "Registration Rights Agreement") among the
Company and Morgan Stanley & Co. Incorporated, Merrill Lynch, Pierce, Fenner &
Smith Incorporated, First Union Capital Markets Corp. and NationsBanc Capital
Markets, Inc. (collectively, the "Placement Agents"). The Exchange Notes will
evidence the same indebtedness as the Senior Notes (which they will replace)
and will be issued pursuant to, and entitled to the benefits of, an indenture
dated as of June 3, 1997 between the Company and the United States Trust
Company of New York, as trustee (the "Trustee"), governing the Senior Notes and
the Exchange Notes (the "Indenture").
                                                       (Continued on next page.)

WHICH INVESTORS SHOULD CONSIDER IN CONNECTION WITH THE EXCHANGE OFFER AND AN

                                  -----------
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.
 
                                  -----------
 
                    THE DATE OF THIS PROSPECTUS IS   , 1997
<PAGE>
 
  The Exchange Notes are redeemable at the option of the Company, in whole or
in part, at any time on or after June 1, 2002, initially at 105.5% of their
principal amount, plus accrued interest, declining ratably to 100% of their
principal amount, plus accrued interest, on or after June 1, 2004. In
addition, at any time prior to June 1, 2000, the Company may redeem up to 35%
of the aggregate principal amount of the Senior Notes and the Exchange Notes
from the proceeds of one or more Public Equity Offerings (as defined herein)
at 111% of their principal amount, plus accrued interest; provided that after
any such redemption at least $130.0 million aggregate principal amount of the
Senior Notes and the Exchange Notes remains outstanding. See "Description of
the Exchange Notes--Certain Definitions."
   
  Approximately $62.7 million of the net proceeds from the Offering (as
defined herein) have been used to purchase a portfolio of U.S. government
securities that have been pledged to secure and fund the first six scheduled
interest payments on the Senior Notes and the Exchange Notes.     
   
  The Exchange Notes will be unsubordinated indebtedness of the Company,
ranking pari passu in right of payment with the Senior Notes and all other
existing and future unsubordinated indebtedness of the Company and senior in
right of payment to all subordinated indebtedness of the Company. After giving
pro forma effect to the Reorganization (as defined herein), as of June 30,
1997, the Company would have had (on an unconsolidated basis) no indebtedness
other than the Senior Notes and the Exchange Notes. However, the Company is a
holding company and the Senior Notes are, and the Exchange Notes will be,
effectively subordinated to all existing and future liabilities (including
trade payables) of the Company's subsidiaries. On June 30, 1997, on the same
pro forma basis, the Company's subsidiaries would have had approximately $37.7
million of liabilities (excluding intercompany payables), including
approximately $14.4 million of indebtedness (including capital leases).     
 
  The Senior Notes were originally issued and sold on June 3, 1997 in a
transaction not registered under the Securities Act (the "Offering").
Accordingly, the Senior Notes may not be offered for resale, resold or
otherwise transferred unless so registered or unless an applicable exemption
from the registration requirements of the Securities Act is available. Based
on interpretations by the staff of the Securities and Exchange Commission (the
"Commission"), as set forth in no-action letters issued to third parties
unrelated to the Company, the Company believes that the Exchange Notes issued
pursuant to the Exchange Offer may be offered for resale, resold or otherwise
transferred by holders thereof (other than any holder that is (i) a broker-
dealer that acquired Senior Notes as a result of market-making activities or
other trading activities or (ii) an "affiliate" of the Company within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration or prospectus delivery provisions of the Securities Act, provided
that such Exchange Notes are acquired in the ordinary course of such holders'
business and such holders have no arrangement or understanding with any person
to participate in a distribution (within the meaning of the Securities Act) of
such Exchange Notes. Any holder who tenders Senior Notes in the Exchange Offer
with the intention to participate, or for the purpose of participating, in a
distribution of the Exchange Notes or who is an affiliate of the Company may
not rely upon such interpretations by the staff of the Commission and, in the
absence of an exemption therefrom, must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
secondary resale transaction. Failure to comply with such requirements in such
instance may result in such holder incurring liabilities under the Securities
Act for which the holder is not indemnified by the Company. The staff of the
Commission has not considered the Exchange Offer in the context of a no-action
letter, and there can be no assurance that the staff of the Commission would
make a similar determination with respect to the Exchange Offer as in such
other circumstances.
 
  By tendering Senior Notes in exchange for Exchange Notes, each holder will
represent to the Company, among other things, that: (i) any Exchange Notes to
be received by such holder will be acquired in the ordinary course of such
holder's business; (ii) such holder has no arrangement or understanding with
any person to participate in a distribution (within the meaning of the
Securities Act) of the Exchange Notes; and (iii) such holder is not an
"affiliate" of the Company (within the meaning of Rule 405 under the
Securities Act), or if such holder is an affiliate, that such holder will
comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Senior Notes, where such
Senior Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver
a prospectus in
 
                                       2
<PAGE>
 
connection with any resale of such Exchange Notes. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-
dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of Exchange Notes received in exchange for Senior Notes where
such Senior Notes were acquired by such broker-dealer as a result of market-
making activities or other trading activities. The Company has agreed that,
for a period not to exceed 180 days after the Expiration Date (as defined
herein), it will furnish additional copies of this Prospectus, as amended or
supplemented, to any broker-dealer that reasonably requests such documents for
use in connection with any such resale. See "Plan of Distribution."
 
  The Company does not intend to apply for listing of the Exchange Notes for
trading on any securities exchange or for inclusion of the Exchange Notes in
any automated quotation system. The Senior Notes, however, have been
designated for trading in the Private Offerings, Resales and Trading through
Automatic Linkages ("PORTAL") Market of the National Association of Securities
Dealers, Inc. Any Senior Notes not tendered and accepted in the Exchange Offer
will remain outstanding. To the extent that Senior Notes are not tendered and
accepted in the Exchange Offer, a holder's ability to sell such Senior Notes
could be adversely affected. Following consummation of the Exchange Offer, the
holders of Senior Notes will continue to be subject to the existing
restrictions on transfer thereof and the Company will have no further
obligation to such holders to provide for the registration under the
Securities Act of the Senior Notes. See "Description of the Exchange Notes--
Exchange Offer; Registration Rights." No assurance can be given as to the
liquidity of either the Senior Notes or the Exchange Notes.
 
  THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF SENIOR NOTES ARE URGED TO READ THIS PROSPECTUS AND THE
RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER
THEIR SENIOR NOTES PURSUANT TO THE EXCHANGE OFFER.
 
  Senior Notes may be tendered for exchange prior to 5:00 p.m., New York City
time, on    , 1997 (such time on such date being hereinafter called the
"Expiration Date"), unless the Exchange Offer is extended by the Company (in
which case the term "Expiration Date" shall mean the latest date and time to
which the Exchange Offer is extended). Tenders of Senior Notes may be
withdrawn at any time prior to the Expiration Date. The Exchange Offer is not
conditioned upon any minimum aggregate principal amount of Senior Notes being
tendered for exchange. The Exchange Offer is, however, subject to certain
events and conditions and to the terms of the Registration Rights Agreement.
Senior Notes may be tendered only in integral multiples of aggregate principal
amount of $1,000. The Company has agreed to pay all expenses of the Exchange
Offer. This Prospectus, together with the Letter of Transmittal, is being sent
to all registered holders of Senior Notes as of    , 1997.
 
  The Company will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby. No underwriter is being used in connection with
the Exchange Offer. See "Use of Proceeds" and "Plan of Distribution."

                                    SUMMARY
   
  The following summary is qualified in its entirety by the more detailed
information and financial statements, the notes thereto and the other financial
data contained elsewhere in this Prospectus. Potential participants in the
Exchange Offer should carefully consider the factors set forth herein under the
caption "Risk Factors" and are urged to read this Prospectus and the related
Letter of Transmittal in its entirety. Unless otherwise indicated, (i) the
information in this Prospectus, other than the historical financial
information, gives effect to the Reorganization (as defined herein) and the
Offering and (ii) references herein to the "Company" or "ITC/\DeltaCom" refer to
ITC/\DeltaCom, Inc. and its subsidiaries. Certain terms used in this Prospectus
are defined in the "Glossary" appearing elsewhere herein.     
 
                                  THE COMPANY
   
  The Company provides retail long distance services to mid-sized and major
regional businesses in the southern United States and is a leading regional
provider of wholesale long-haul services to other telecommunications companies
using the Company's owned, operated and managed fiber optic network (the
"Carriers' Carrier Services"). The Company intends to become a leading regional
provider of integrated telecommunications services to mid-sized and major
regional businesses in the southern United States by offering such customers a
broad range of telecommunications services, including local exchange and long
distance data and voice, Internet and operator services, and the sale and
servicing of customer premise equipment (collectively, the "Retail Services"),
in a single package tailored to the business customer's specific needs. In
1996, the Company had pro forma revenues of approximately $85.4 million,
earnings before extraordinary item, preacquisition (earnings) losses, equity in
losses of unconsolidated subsidiaries, net interest, income taxes, depreciation
and amortization ("EBITDA") of approximately $18.9 million and net loss from
continuing operations of approximately $12.1 million. For the six months ended
June 30, 1997, the Company had pro forma revenues of approximately $54.3
million, EBITDA of approximately $11.7 million and net loss from continuing
operations of approximately $4.5 million.     
   
  The Company provides Carriers' Carrier Services to other telecommunications
carriers, including AT&T, MCI, Sprint, WorldCom, Cable & Wireless, LCI,
Frontier and IXC. The Company's fiber optic network reaches over 60 points of
presence ("POPs") in ten southern states (Alabama, Arkansas, Florida, Georgia,
Louisiana, Mississippi, North Carolina, South Carolina, Tennessee and Texas)
and extends approximately 5,400 route miles, of which approximately 2,500 miles
are Company-owned and approximately 2,900 miles are owned and operated by three
public utilities (Duke Power Company, Florida Power & Light Company and Entergy
Technology Company) and managed and marketed by the Company. The Company
expects to add approximately 700 owned and operated route miles to its fiber
network by the end of 1997 and add approximately 100 owned and operated route
miles in early 1998 through long-term dark fiber leases. In 1996, the Company's
Carriers' Carrier Services business generated pro forma revenues of
approximately $20.2 million, EBITDA of approximately $11.5 million and net loss
from continuing operations of approximately $1.8 million. For the six months
ended June 30, 1997, the Company's Carriers' Carrier Services business
generated pro forma revenues of approximately $14.3 million, EBITDA of
approximately $8.5 million and net income from continuing operations of less
than $0.1 million. As of June 30, 1997, on a pro forma basis, the Company had
remaining future long-term contract commitments totaling approximately $75.8
million. These contracts expire on various dates through 2006 and are expected
to generate approximately $56.0 million in revenues to the Company through
2001, of which approximately $14.5 million are expected to be realized in 1998.
    
   
  The Company currently provides a variety of Retail Services, including retail
long distance services such as traditional switched and dedicated long
distance, 800/888 calling, calling card and operator services, Asynchronous
Transfer Mode ("ATM"), frame relay, high capacity broadband private line
services, as well as Internet, Intranet and Web page hosting and development
services, and customer premise equipment installation and repair. As of June
30, 1997, the Company provided services to over 6,600 business customers. The
Company currently offers Retail Services, other than local exchange services
(which are provided in two markets), in 12

metropolitan areas in Alabama, Florida, Georgia, Louisiana, North Carolina and
South Carolina and intends to provide a full range of Retail Services
(including local exchange services) in approximately 15 additional metropolitan
areas throughout the southern United States over the next five years. In 1996,
the Retail Services business generated pro forma revenues of approximately
$65.2 million, EBITDA of approximately $7.4 million and net loss from
continuing operations of approximately $3.7 million. For the six months ended
June 30, 1997, the Retail Services business generated pro forma revenues of
approximately $39.9 million, EBITDA of approximately $3.2 million and net loss
from continuing operations of approximately $2.2 million.     
   
  In July 1997, the Company began offering local services on a limited, resale
basis in Birmingham and Montgomery, Alabama, and commenced a general sales
effort of services on a resale basis in those markets in August 1997. Also in
August 1997, the Company initiated a limited offering in Birmingham and
Montgomery of facilities-based local services, and expects that general
marketing of such services will commence in September 1997. Although the
Company's local exchange services offerings in such markets are in the very
early stages, initial expressions of customer interest in such services have
been positive, consistent with management's expectations. However, there can be
no assurance that demand for the Company's local services will match such
preliminary indications of customer interest. The Company expects to offer
local exchange services as part of its Retail Services in six to nine markets
(including Birmingham and Montgomery) by the end of 1997, initially by
reselling the services of incumbent local exchange carriers and, where market
conditions warrant, by using its own local switching facilities.     
   
  In connection with offering local exchange services, the Company has entered
into an Interconnection Agreement (the "Interconnection Agreement") with
BellSouth Telecommunications, Inc. ("BellSouth") to (i) resell BellSouth's
local exchange services and (ii) interconnect the Company's network with
BellSouth's network for the purpose of immediately gaining access to all of
BellSouth's unbundled network elements. This agreement will allow the Company
to enter new markets with minimal capital expenditures and to offer local
exchange services to its current customer base. The Interconnection Agreement
currently allows the Company to provide local service on a resale basis or by
purchasing all unbundled network elements required to provide local service on
a facilities bases, without using Company-owned facilities. The terms of the
Interconnection Agreement, including interim pricing terms agreed to by the
Company and BellSouth, have been approved by state regulatory authorities in
most states, although they remain subject to review and modification by such
authorities. In addition, the Interconnection Agreement does not resolve all
operational issues, particularly those relating to the collocation of the
Company's equipment with that of BellSouth. The Company and BellSouth are
continuing to negotiate to resolve such issues. The Company expects that the
Interconnection Agreement will provide a foundation for it to provide local
service on a reasonable commercial basis, but there can be no assurance of this
and important issues remain unsettled as a result of legal and regulatory
developments and related matters. The Interconnection Agreement expires in
1999, and there can be no assurance that the Company will be able to renew it
under favorable terms, or at all.     
 
BUSINESS STRATEGY
   
  The Company's objectives are to maintain its leadership position in the
provision of Carriers' Carrier Services and to become a leading provider of
Retail Services in the southern United States. The Company intends to increase
its market share in existing markets and expand into new markets by (i)
aggressively expanding its customer base and increasing its telecommunications
services, including reselling services and facilities of the incumbent local
exchange carriers; (ii) leveraging the Company's extensive network in its
Retail Services and Carriers' Carrier Services businesses; (iii) concurrently
constructing or obtaining access to additional network infrastructure to serve
its customers more cost-effectively; and (iv) expanding its regional network of
sales offices. The principal elements of the Company's business strategy
include the following:     
 
  PROVIDING INTEGRATED TELECOMMUNICATIONS SERVICES TO EXISTING BASE OF MID-
SIZED AND MAJOR REGIONAL BUSINESS CUSTOMERS. By providing additional
telecommunications services such as local telephone service to its existing,
well-established base of long distance customers, the Company expects to be
able to increase revenues at relatively low incremental cost. The Company
believes that bundling a variety of telecommunications services and presenting
customers with one fully integrated monthly billing statement for all of those
services
 
                                       5
<PAGE>
 
will allow it to penetrate its target markets rapidly and build customer
loyalty. The Company believes that there is substantial demand in its target
markets among mid-sized and major regional business customers for an integrated
package of telecommunications services that meets all of their
telecommunications needs.
   
  LEVERAGING ITS EXTENSIVE FIBER OPTIC NETWORK. The Company intends to leverage
its extensive fiber optic network, which currently reaches over 60 POPs, by (i)
continuing to provide switched and transport services to other communications
carriers throughout its region to enable such carriers to diversify their
routes and expand their networks; (ii) targeting customers that need to
transmit large amounts of data within the Company's service region, such as
banks and local and state governments; and (iii) offering local exchange
services to its business customers, which began on a limited basis in the
second half of 1997, as part of its integrated package of telecommunications
services. The Company intends initially to provide local exchange services by
reselling the services of incumbent local exchange carriers and, in some
established markets, using its own local switching facilities. Over time, the
Company expects to provide local services primarily using the Company's own
switching facilities and existing regional fiber optic network, supplemented by
unbundled facilities of incumbent local exchange carriers or other competitive
local exchange carriers. The configuration of the Company's network enables the
Company to expand its network by installing additional remote local switches,
which operate in conjunction with the Company's DMS-500 switches to provide
facilities-based local services. Because remote local switches are less
expensive to purchase and install than DMS-500 switches, and can be installed
more quickly than DMS-500 switches, the Company believes that it will be able
to enter new markets at less expense than many of its competitors. At present,
the Company does not plan to construct intra-city local loop facilities.     
 
  FOCUSING ON THE SOUTHERN UNITED STATES. The Company intends to continue to
focus on the southern United States in order to leverage its extensive
telecommunications network in the region. The Company believes that its
regional focus will enable it to take advantage of economies of scale in
management, network operations and sales and marketing. The regional
concentration of the Company's network also provides an opportunity for
improved margins because a high portion of its customers' telecommunications
traffic originates and terminates within the region. The Company also believes
that its regional focus will enable it to build on its long-standing customer
and business relationships in the region.
   
  BUILDING MARKET SHARE THROUGH PERSONALIZED CUSTOMER SERVICE. The Company
believes that the key to revenue growth in its target markets is capturing and
retaining customers by emphasizing marketing, sales and customer service.
Management believes that customers prefer one company to be accountable for
their telecommunications services, and that a consultative, face-to-face sales
and service strategy is the most effective method of acquiring and maintaining
a high quality customer base. The Company seeks to obtain long-term commitments
from its business customers by responding rapidly and creatively to their
telecommunications needs. The Company currently operates 14 sales offices in
Alabama, Florida, Georgia, Louisiana, North Carolina and South Carolina. Each
sales office is staffed by personnel capable of marketing all of the Company's
products and providing comprehensive support to the Company's customers.     
   
  EXPANDING ITS FIBER OPTIC NETWORK AND SWITCHING FACILITIES. The Company
expects to expand its fiber optic telecommunications network and switching
facilities to include additional markets within the southern United States. The
Company currently owns and operates approximately 2,500 route miles of fiber
optic network extending from Georgia to Texas, with an additional 700 owned and
operated route miles expected to be added by the end of 1997 and approximately
100 owned and operated route miles expected to be added in early 1998. The
Company also markets and manages capacity on 2,900 additional network route
miles through its strategic relationships with public utilities. In addition,
the Company has 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 the Company to provide customers with access to POPs throughout
those states. The Company believes that, by continuing to combine its owned
network with the networks of public utilities and by adding switching
facilities throughout its network, it will be able to achieve capital
efficiencies and rapidly expand its network in a cost-effective manner.

  LEVERAGING PROVEN MANAGEMENT TEAM. The Company's management team consists of
experienced telecommunications managers who in the past have successfully
implemented a customer-focused long distance telecommunications strategy in the
southern United States. Members of the team include Andrew Walker, Chief
Executive Officer of the Company, Foster McDonald, President of the Company,
and Douglas Shumate, Chief Financial Officer of the Company. ITC Holding
Company, Inc. ("ITC Holding"), a diversified company with substantial holdings
in telecommunications businesses operating in the southern United States, is
the Company's sole stockholder. The Company anticipates that ITC Holding's
experience and contacts in the telecommunications industry will enhance the
Company's development.     
 
HISTORY OF THE COMPANY
   
  ITC/\DeltaCom was incorporated in March 1997 as a wholly owned subsidiary of
ITC Holding to acquire and operate ITC Holding's Retail Services and Carriers'
Carrier Services businesses. The Company acquired such businesses on July 25,
1997 in the Reorganization as described below.     
   
  BACKGROUND. ITC Holding has provided operator and directory assistance
services since March 1993 through its subsidiary, Eastern Telecom, Inc., which
does business as InterQuest ("InterQuest"). Carriers' Carrier Services have
been offered since April 1992 through Interstate FiberNet, a partnership
originally formed by ITC Holding (with a 49% interest) and SCANA
Communications, Inc. ("SCANA") (with a 51% interest). In August 1994, ITC
Holding acquired SCANA's interest in Interstate FiberNet through ITC
Transmission Systems II, Inc., a wholly owned subsidiary of ITC Holding
("Transmission II"). Also in August 1994, ITC Holding and SCANA formed a second
partnership, Gulf States FiberNet, to construct and operate a fiber optic route
primarily between Atlanta, Georgia and Shreveport, Louisiana with several
supplemental spur routes. In a transaction consummated in March 1997 (the "Gulf
States Acquisition"), ITC Holding acquired SCANA's 64% partnership interest in
Gulf States FiberNet and certain fiber and fiber-related assets, including a
significant customer contract for network services in Georgia (the "Georgia
Fiber Assets"). Following the Gulf States Acquisition, ITC Holding contributed
the remaining 64% interest in Gulf States FiberNet to Gulf States Transmission
Systems, Inc., a wholly owned subsidiary of ITC Holding ("Gulf States
Transmission"), and the Georgia Fiber Assets to ITC Transmission Systems, Inc.,
a wholly owned subsidiary of ITC Holding ("Transmission"). Members of the
Company's management have been managing the businesses of both Interstate
FiberNet and Gulf States FiberNet since their inception.     
   
  In January 1996, through its acquisition (the "DeltaCom Acquisition") of
DeltaCom, Inc. ("DeltaCom"), ITC Holding entered the retail long distance
business and acquired several fiber optic routes within the state of Alabama
that complemented the existing networks operated by Interstate FiberNet
(including a fiber route from Atlanta, Georgia to Columbus, Georgia) and Gulf
States FiberNet. DeltaCom, a provider of telecommunications services since its
inception in 1982, provides long distance services to mid-sized businesses
primarily in Alabama. In July 1996, DeltaCom purchased substantially all of the
assets of the Internet business of Viper Computer Systems, Inc. ("ViperNet"),
which provides Internet access, Web-hosting and Web page development services
to business customers.     
   
  To finance the DeltaCom Acquisition and to refinance existing DeltaCom debt,
ITC Holding incurred approximately $74.0 million of indebtedness, which was
pushed down to the Company (the "DeltaCom Indebtedness"). The aggregate
consideration paid by ITC Holding in the Gulf States Acquisition was
approximately $27.9 million, of which $10.0 million consisted of an unsecured
note (the "SCANA Note"), which has been assumed by a subsidiary of the Company,
and $17.9 million consisted of ITC Holding preferred stock. In connection with
the Gulf States Acquisition, Gulf States Transmission borrowed $41.6 million
under a credit facility (the "Bridge Facility") with NationsBank, N.A., to
refinance a project loan incurred by Gulf States FiberNet.     
          
  SENIOR NOTE OFFERING. On June 3, 1997, the Company completed the sale of $200
million principal amount of Senior Notes in a private offering. The net
proceeds from the sale of the Senior Notes, other than the portion     
 
                                       7
<PAGE>
 
   
of such proceeds invested in U.S. government securities pledged to secure and
fund the first six scheduled interest payments on the Senior Notes and the
Exchange Notes (the "Pledged Securities"), were released to the Company upon
consummation of the Reorganization.     
   
  REORGANIZATION. On July 25, 1997, ITC Holding contributed to the Company in a
series of transactions the businesses of Interstate FiberNet, Gulf States
FiberNet, DeltaCom and InterQuest (such transactions collectively referred to
herein as the "Reorganization"). In connection with the Reorganization,
approximately $31.0 million of the $74.0 million of the DeltaCom Indebtedness
was forgiven by ITC Holding and contributed to the Company as additional
equity. Following the Reorganization, the Company repaid the remaining
$43.0 million of the DeltaCom Indebtedness, accrued interest on all $74.0
million of such indebtedness and the $41.6 million of indebtedness outstanding
under the Bridge Facility and accrued interest thereon with a portion of the
net proceeds from the Offering. See "Use of Proceeds."     
 
                               THE EXCHANGE OFFER

                            conditions, which may be waived by the Company in
                            its sole discretion. The Exchange Offer is not
                            conditioned upon any minimum aggregate principal

                            absolute discretion, subject to applicable law, at
                            any time and from time to time, (i) to delay the
                            acceptance of the Senior Notes, (ii) to terminate
                            the Exchange Offer if certain specified conditions

                            conformity with certain procedures as set forth
                            below under "The Exchange Offer--Withdrawal
                            Rights."
 
Procedures for Tendering  
 Senior Notes.............  Tendering holders of Senior Notes must complete and
                            sign a Letter of Transmittal in accordance with the
                            instructions contained therein and forward the same
                            by mail, facsimile transmission or hand delivery,
                            together with any other required documents, to the
                            Exchange Agent, either with the Senior Notes to be
                            tendered or in compliance with the specified
                            procedures for guaranteed delivery of Senior Notes.
                            Certain brokers, dealers, commercial banks, trust
                            companies and other nominees may also effect
                            tenders by book-entry transfer. Holders of Senior
                            Notes registered in the name of a broker, dealer,
                            commercial bank, trust company or other nominee are
                            urged to contact such person promptly if they wish
                            to tender Senior Notes pursuant to the Exchange
                            Offer. See "The Exchange Offer--Procedures for
                            Tendering Senior Notes."
 
                            Letters of Transmittal and certificates
                            representing Senior Notes should not be sent to the
                            Company. Such documents should only be sent to the
                            Exchange Agent. Questions regarding how to tender
                            and requests for information should be directed to
                            the Exchange Agent. See "The Exchange Offer--
                            Exchange Agent."
 
Resales of Exchange       
Notes.....................  Based on interpretations by the staff of the
                            Commission, as set forth in no-action letters
                            issued to third parties, the Company believes that
                            holders of Senior Notes (other than any holder that
                            is (i) a broker-dealer that acquired Senior Notes
                            as a result of market-making activities or other
                            trading activities or (ii) an "affiliate" of the
                            Company within the meaning of Rule 405 under the
                            Securities Act) who exchange their Senior Notes for
                            Exchange Notes pursuant to the Exchange Offer may
                            offer for resale, resell and otherwise transfer
                            such Exchange Notes without compliance with the
                            registration and prospectus delivery provisions of
                            the Securities Act, provided that such Exchange
                            Notes are acquired in the ordinary course of such
                            holders' business and such holders have no
                            arrangement or understanding with any person to
                            participate in a distribution (within the meaning
                            of the Securities Act) of such Exchange Notes. Any
                            holder who tenders Senior Notes in the Exchange
                            Offer with the intention to participate, or for the
                            purpose of participating, in a distribution of the
                            Exchange Notes or who is an affiliate of the
                            Company may not rely upon such interpretations by
                            the staff of the Commission and, in the absence of
                            an exemption therefrom, must comply with the
                            registration and prospectus delivery requirements
                            of the Securities Act in connection with any
                            secondary resale transaction. Failure to comply
                            with such requirements in such instance may result
                            in such holder incurring liabilities under the
                            Securities Act for which the holder is not
                            indemnified by the Company. The staff of the
                            Commission has not considered the Exchange Offer in
                            the context of a no-action letter, and there can be
                            no assurance that the staff of the
 
                                       9
<PAGE>
 
                            Commission would make a similar determination with
                            respect to the Exchange Offer. Each broker-dealer
                            that receives Exchange Notes for its own account in
                            exchange for Senior Notes, where such Senior Notes
                            were acquired by such broker-dealer as a result of
                            market-making activities or other trading
                            activities, must acknowledge that it will deliver a

Certain United States     
 Federal Income Tax       
 Consequences.............  The exchange of the Senior Notes for the Exchange
                            Notes will not be a taxable exchange for federal
                            income tax purposes, and holders of Senior Notes
                            should not recognize any taxable gain or loss or
                            any interest income as a result of such exchange.
                            See "The Exchange Offer--Certain United States
                            Federal Income Tax Consequences."
 
                               THE EXCHANGE NOTES
 
Securities Offered........  $200 million aggregate principal amount of 11%
                            Senior Notes dueJune 1, 2007. The terms of the
                            Exchange Notes will be identical in all material
                            respects to the terms of the Senior Notes, except
                            that (i) the Exchange Notes will have been
                            registered under the Securities Act and therefore
                            will not be subject to certain restrictions on
                            transfer applicable to the Senior Notes and (ii)
                            holders of the Exchange Notes will not be entitled
                            to certain rights of holders of the Senior Notes
                            under the Registration Rights Agreement. The
                            Exchange Notes will evidence the same debt as the
                            Senior Notes and will be issued pursuant to and

Maturity..................  June 1, 2007.
 
Interest..................  Interest on the Exchange Notes is payable
                            semiannually in cash, on each June 1 and December
                            1, commencing December 1, 1997.
 
                               
Security..................  Pursuant to the Indenture, approximately $62.7
                            million of the net proceeds from the Offering were
                            used by the Trustee to purchase a portfolio of
                            Pledged Securities (consisting only of U.S.
                            government securities) that are being held as
                            security for the payment of the first six scheduled
                            interest payments due on the Senior Notes and the
                            Exchange Notes. The Pledged Securities are being
                            and will be held by the Trustee for the benefit of
                            the holders of the Senior Notes and the Exchange
                            Notes under a Pledge and Security Agreement dated
                            June 3, 1997 between the Company and the Trustee
                            (the "Pledge Agreement"), pending disbursement.
                            After the first six scheduled interest payments on
                            the Senior Notes and Exchange Notes are made, the
                            Senior Notes and the Exchange Notes will be
                            unsecured. See "Description of the Exchange Notes--
                            Security."     
 
Optional Redemption.......  The Exchange Notes may be redeemed at any time on
                            or after June 1, 2002, at the option of the
                            Company, in whole or in part, at 105.5% of their
                            principal amount, plus accrued interest, declining
                            ratably to 100% of their principal amount, plus
                            accrued interest, on and after June 1, 2004. In
                            addition, at any time prior to June 1, 2000, up to
                            35% of the aggregate principal amount of the Senior
                            Notes and the Exchange Notes may be redeemed from
                            the proceeds of one or more Public Equity Offerings
                            at 111% of their principal amount plus accrued
                            interest; provided that after any such redemption
                            at least $130.0 million aggregate principal amount
                            of the Senior Notes and the Exchange Notes remains
                            outstanding.
                                   
       
                               
Change of Control.........  Upon a Change of Control (as defined herein), the
                            Company will be required to make an offer to
                            purchase the Exchange Notes at a purchase price
                            equal to 101% of their principal amount, plus
                            accrued interest. There can be no assurance that
                            the Company will have sufficient funds available at
                            the time of any Change of Control to make any
                            required debt repayment (including repurchases of
                            the Exchange Notes). See "Description of the
                            Exchange Notes--Repurchases of Exchange Notes upon
                            a Change of Control," and "Description of the
                            Exchange Notes--Certain Definitions."     
 
                               
Ranking...................  The Exchange Notes will be unsubordinated
                            indebtedness of the Company, ranking pari passu in
                            right of payment with the Senior Notes and all
                            other existing and future unsubordinated
                            indebtedness of the Company and senior in right of
                            payment to all subordinated indebtedness of the
                            Company. After giving pro forma effect to the
                            Reorganization and the use of the net proceeds from
                            the Offering, at June 30, 1997, the Company (on an
                            unconsolidated basis) would have had no other
                            indebtedness other than the Senior Notes. In
                            addition, the Exchange Notes will be unsecured
                            (except as described under""--Security") and will
                            be effectively subordinated to all secured     
 
                                       11

                            indebtedness. The Company is a holding company and
                            the Senior Notes are, and the Exchange Notes will
                            be, effectively subordinated to all existing and
                            future liabilities (including trade payables) of
                            the Company's subsidiaries. On June 30, 1997, on
                            the same pro forma basis, the subsidiaries of the
                            Company would have had approximately $37.8 million
                            of liabilities (excluding intercompany payables),
                            including approximately $14.4 million of
                            indebtedness (including capital leases). A
                            subsidiary of the Company has received a commitment
                            letter (the "Commitment Letter") from NationsBank
                            of Texas, N.A. ("NationsBank") for a secured credit
                            facility (the "Credit Facility") of up to $100
                            million to be used for working capital and other
                            purposes, including capital expenditures and
                            permitted acquisitions. The Credit Facility is
                            expected to be secured by substantially all of the
                            assets of the Company's subsidiaries. The Company
                            and its other subsidiaries will guarantee all
                            obligations under the Credit Facility. Indebtedness
                            under the Credit Facility will be effectively
                            senior to the Exchange Notes to the extent of such
                            security interests. See "Risk Factors--Holding
                            Company Structure; Priority of Secured Debt."     
 
Certain Covenants.........  The Indenture contains certain covenants that,
                            among other things, limit the ability of the
                            Company to incur indebtedness, pay dividends,
                            prepay subordinated indebtedness, repurchase
                            capital stock, make investments, engage in
                            transactions with stockholders and affiliates,
                            create liens, sell assets and engage in mergers and
                            consolidations. However, these limitations are
                            subject to a number of important qualifications and
                            exceptions. See "Description of the Exchange
                            Notes--Covenants."
 
                                  RISK FACTORS
 
  Potential participants in the Exchange Offer should consider carefully
certain factors relating to the Company, its business and an investment in the
Exchange Notes before tendering their Senior Notes for Exchange Notes. See
"Risk Factors."

                      SUMMARY FINANCIAL AND OPERATING DATA
   
  The summary historical and pro forma financial and operating data set forth
below should be read in conjunction with "History of the Company," "Use of
Proceeds," "Selected Financial and Operating Data," "Pro Forma Financial Data,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," the financial statements and notes thereto, and other financial
and operating data contained elsewhere in this Prospectus. The pro forma
statement of operations data for 1996 give effect to the following transactions
as if each had occurred on January 1, 1996: (i) the DeltaCom Acquisition; (ii)
the Gulf States Acquisition; (iii) the Reorganization; and (iv) the Offering
and the use of the net proceeds therefrom. The pro forma statement of
operations data for the six months ended June 30, 1997 give effect to the
following transactions as if each had occurred on January 1, 1996: (i) the Gulf
States Acquisition; (ii) the Reorganization; and (iii) the Offering and the use
of the net proceeds therefrom. The pro forma balance sheet data at June 30,
1997 give effect to (i) the Reorganization, including ITC Holding's forgiveness
and contribution of approximately $31.0 million of the DeltaCom Indebtedness to
the Company as additional equity and (ii) the use of the net proceeds from the
Offering as if such transactions had occurred on June 30, 1997. The pro forma
financial and operating information does not purport to represent what the
Company's consolidated results of operations would have been if these
transactions had in fact occurred on these dates, nor does it purport to
indicate the future consolidated financial position or consolidated results of
future operations of the Company. The pro forma adjustments are based on
currently available information and certain assumptions that management
believes to be reasonable.

(a) Through August 17, 1994, the Company owned a 49% interest in Interstate
    FiberNet and accounted for this investment under the equity method. On
    August 17, 1994, the Company purchased the remaining 51% interest in
    Interstate FiberNet from SCANA. Therefore, Interstate FiberNet's revenues
    and expenses have been included in the combined statement of operations
    data effective January 1, 1994, with the preacquisition earnings
    attributable to SCANA deducted to determine the combined net income for
    1994. See note 5 to the combined financial statements.
(b) On August 17, 1994, the Company entered into the Gulf States FiberNet
    partnership with SCANA. The Company obtained a 36% general partnership
    interest and the investment was accounted for under the equity method. See
    note 5 to the combined financial statements.
(c) On January 29, 1996, ITC Holding purchased DeltaCom. DeltaCom's results of
    operations are included in the historical statement of operations data
    since the date of acquisition. See note 13 to the combined financial
    statements.
   
(d) On March 27, 1997, the Company purchased the remaining 64% partnership
    interest in Gulf States FiberNet from SCANA. Therefore, Gulf States
    FiberNet's revenues and expenses have been included in the combined
    statement of operations data effective January 1, 1997 with the
    preacquisition losses attributable to SCANA deducted to determine the
    combined net loss for the six months ended June 30, 1997. See note 16 to
    the combined financial statements.     
   
(e) On March 27, 1997, the Company purchased the Georgia Fiber Assets from
    SCANA. The results of operations for the Georgia Fiber Assets were included
    in the combined statements of operations beginning April 1, 1997. See note
    16 to the combined financial statements.     
   
(f) EBITDA represents earnings before extraordinary item, preacquisition
    (earnings) losses, equity in losses of unconsolidated subsidiaries, net
    interest, income taxes, depreciation and amortization. EBITDA is provided
    because it is a measure commonly used in the industry. EBITDA is not a
    measurement 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 is
    not necessarily comparable with similarly titled measures for other
    companies. Pro forma consolidated EBITDA for the year ended December 31,
    1996 and the six months ended June 30, 1997 includes an estimated $3.4
    million and $1.8 million, respectively, of interest income that would have
    been earned on the estimated $62.7 million invested in Pledged Securities.
           
(g) Earnings consist of income before income taxes, plus fixed charges. Fixed
    charges consist of interest charges and amortization of debt issuance costs
    (including those reflected as an extraordinary item) 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, 1995, 1996 and pro forma 1996 and
    the six months ended June 30, 1996, 1997 and pro forma 1997 by $.8 million,
    $5.1 million, $18.2 million, $2.3 million, $3.8 million and $6.6 million,
    respectively.

                                 RISK FACTORS
 
  In addition to the other information contained in this Prospectus, holders
of Senior Notes should consider carefully the following factors before
tendering their Senior Notes for Exchange Notes.
 
HISTORICAL AND ANTICIPATED FUTURE OPERATING LOSSES AND NEGATIVE CASH FLOW
AFTER CAPITAL EXPENDITURES
   
  The Company expects to incur significant and increasing operating losses and
negative cash flow (after capital expenditures) during the next several years
as it implements its business strategy to expand its telecommunications
service offerings, expand its fiber optic network and enter new markets.
Although the Company expects that a majority of its revenue growth will come
from Retail Services, it does not expect its Retail Services to obtain a
significant share of the market for telecommunications services in the
southern United States, and there can be no assurance that the Company will
achieve or sustain profitability or positive net cash flow in the future. If
the Company cannot achieve or sustain operating profitability and positive net
cash flow, it may not be able to meet its working capital or debt service
requirements, which could have a material adverse effect on the Company's
ability to meet its obligations on the Exchange Notes. See "--Significant
Capital Requirements; Uncertainty of Additional Financing," "Selected
Financial and Operating Data," "Pro Forma Financial Data" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
    
SIGNIFICANT CAPITAL REQUIREMENTS; UNCERTAINTY OF ADDITIONAL FINANCING
   
  Expansion of the Company's network, operations and services will require
significant capital. The Company currently estimates that its aggregate
capital requirements will total approximately $104 million in 1997 and 1998,
of which approximately $50 million is expected to be incurred in 1997
(including $12.4 million of capital expenditures made as of June 30, 1997) and
$54 million in 1998. The Company anticipates making substantial capital
expenditures thereafter. Capital expenditures will be primarily for: the
addition of facilities-based local telephone service to the Company's bundle
of integrated telecommunications services, including acquisition and
installation of switches; market expansion; continued development and
construction of its fiber optic network (including transmission equipment);
and infrastructure enhancements, principally for information systems. The
Company believes that the net proceeds from the Offering, together with cash
flow from operations and borrowings expected to be available under the Credit
Facility, will provide sufficient funds to enable the Company to expand its
business as currently planned through the expected maturity of the Credit
Facility in 2002, after which the Company will need to seek additional
financing to fund capital expenditures and working capital. Because the Credit
Facility is expected to mature in 2002, the Company may not have a ready
source of liquidity after 2002. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Description of Certain
Indebtedness."     
 
  The actual amount and timing of the Company's future capital requirements
may differ materially from the Company's estimate depending on the demand for
the Company's services and as a result of regulatory, technological and
competitive developments (including new market developments and new
opportunities) in the Company's industry. The Company may also require
additional capital in the future (or sooner than currently anticipated) for
new business activities related to its current and planned businesses, or in
the event it decides to make additional acquisitions or enter into joint
ventures and strategic alliances. Sources of additional capital may include
cash flow from operations and public and private equity and debt financings.
There can be no assurance, however, that the Company will be successful in
producing sufficient cash flows or raising sufficient debt or equity capital
to meet its strategic objectives or that such funds, if available at all, will
be available on a timely basis or on terms that are acceptable to the Company.
Failure to generate or raise sufficient funds would require the Company to
delay or abandon some or all of its future expansion plans or expenditures,
which could have a material adverse effect on the Company. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Overview."
 
HIGH LEVERAGE; ABILITY TO SERVICE DEBT; RESTRICTIVE COVENANTS
   
  At June 30, 1997, on a pro forma basis, giving effect to the Reorganization
and the use of the net proceeds from the Offering, the Company would have had
$214.4 million of indebtedness and its stockholder's equity     
 
                                      15
<PAGE>
 
   
would have been $64.1 million. On a pro forma basis, the Company's earnings
would have been insufficient to cover its fixed charges for the year ended
December 31, 1996 and the six months ended June 30, 1997 by $18.2 million and
$6.6 million, respectively, and its EBITDA less capital expenditures and
interest expense would have been negative $14.8 million and negative $13.0
million, respectively.     
   
  The Indenture contains, and the Credit Facility will contain, restrictions
on the Company and its subsidiaries that affect, and in certain cases
significantly limit or prohibit, among other things, the ability of the
Company and its subsidiaries to incur additional indebtedness, create liens,
make investments, issue stock of subsidiaries and sell assets. In addition,
the Credit Facility is expected to require the Company to maintain certain
financial ratios. See "Description of Certain Indebtedness--Credit Facility."
There can be no assurance that the Company will be able to maintain such
ratios or that such covenants will not adversely affect the Company's ability
to finance its future operations or capital needs or to engage in other
business activities that may be in the interest of the Company. The
limitations in the Indenture are subject to a number of important
qualifications and exceptions. In particular, while the Indenture restricts
the Company's ability to incur indebtedness by requiring compliance with
specified leverage ratios, it permits the Company to incur an unlimited amount
of additional indebtedness to finance the acquisition of equipment, inventory
or network assets.     
 
  There can be no assurance that the Company will be able to improve its
earnings before fixed charges or that the Company will be able to meet its
debt service obligations, including its obligations on the Exchange Notes. If
the Company is unable to generate sufficient cash flow or otherwise obtain
funds necessary to make required payments, or if the Company otherwise fails
to comply with the various covenants in its debt obligations, it would be in
default under the terms thereof, which would permit the holders of such
indebtedness to accelerate the maturity of such indebtedness and could cause
defaults under other indebtedness of the Company. Such defaults could result
in a default on the Exchange Notes and could delay or preclude payment of
interest or principal on the Exchange Notes. The ability of the Company to
meet its obligations will be dependent upon the future performance of the
Company, which will be subject to prevailing economic conditions and to
financial, business and other factors. See "Description of Certain
Indebtedness" and "Description of the Exchange Notes--Covenants."
 
  The level of the Company's indebtedness could adversely affect the Company
in a number of ways. For example, (i) the ability of the Company to obtain any
necessary financing in the future for working capital, capital expenditures,
debt service requirements or other purposes may be limited; (ii) the Company's
level of indebtedness could limit its flexibility in planning for, or reacting
to, changes in its business; (iii) the Company will be more highly leveraged
than some of its competitors, which may place it at a competitive
disadvantage; (iv) the Company's degree of indebtedness may make it more
vulnerable to a downturn in its business or the economy generally; (v) the
debt service requirements of any additional indebtedness could make it more
difficult for the Company to make payments on the Exchange Notes; and (vi) a
substantial portion of the Company's cash flow from operations must be
dedicated to the payment of principal and interest on its indebtedness and
will not be available for other purposes.
 
  The successful implementation of the Company's strategy, including expansion
of its network and obtaining and retaining a significant number of customers,
and significant and sustained growth in the Company's cash flow are necessary
for the Company to be able to meet its debt service requirements, including
its obligations under the Exchange Notes. There can be no assurance that the
Company will successfully implement its strategy or that the Company will be
able to generate sufficient cash flow from operating activities to meet its
debt service obligations and working capital requirements. In the event the
implementation of the Company's strategy is delayed or is unsuccessful or the
Company does not generate sufficient cash flow to meet its debt service and
working capital requirements, the Company may need to seek additional
financing. There can be no assurance that any such financing could be obtained
on terms that are acceptable to the Company, or at all. In the absence of such
financing, the Company could be forced to dispose of assets in order to make
up for any shortfall in the payments due on its indebtedness under
circumstances that might not be favorable to realizing the highest price for
such assets. A substantial portion of the Company's assets consist of
intangible assets, the value of which will depend upon a variety of factors
(including the success of the Company's business). As a result, there can
 
                                      16
<PAGE>
 
be no assurance that the Company's assets could be sold quickly enough or for
sufficient amounts to enable the Company to meet its obligations, including
its obligations with respect to the Exchange Notes.
 
ABILITY TO MANAGE GROWTH
 
  The expansion and development of the Company's business will depend on,
among other things, the Company's ability to successfully implement its sales
and marketing strategy, evaluate markets, design fiber routes, secure
financing, install facilities, acquire rights of way, obtain any required
government authorizations, implement interconnection to, and co-location with,
facilities owned by incumbent local exchange carriers and obtain appropriately
priced unbundled network elements and wholesale services from the incumbent
local exchange carriers, all in a timely manner, at reasonable costs and on
satisfactory terms and conditions. The Company's rapid growth, particularly in
the provision of Retail Services, has placed, and anticipated growth in other
services in the future may also place, a significant strain on its
administrative, operational and financial resources. The Company's ability to
continue to manage its growth successfully will require the Company to enhance
its operational, management, financial and information systems and controls
and to hire and retain qualified sales, marketing, administrative, operating
and technical personnel. There can be no assurance that the Company will be
able to do so. In addition, as the Company increases its service offerings and
expands its targeted markets, there will be additional demands on customer
support, sales and marketing, administrative resources and network
infrastructure. The Company's inability to manage its growth effectively could
have a material adverse effect on the Company's business, results of
operations and financial condition.
 
BUSINESS DEVELOPMENT AND EXPANSION RISKS
 
  The successful implementation of the Company's business strategy to provide
an integrated bundle of telecommunications services and expand its operations
will be subject to a variety of risks, including competition and pricing, the
availability of capital on favorable terms, regulatory uncertainties,
operating and technical problems, the need to establish interconnection and
co-location arrangements with incumbent local exchange carriers in its target
markets and the potential difficulties in adding a local service offering. See
"--Dependence on Incumbent Local Exchange Carriers." In addition, the
expansion of the Company's business may involve acquisitions of other
telecommunications businesses and assets that, if made, could divert the
resources and management time of the Company and could require integration
with the Company's operations. There can be no assurance that any such
acquisition could be successfully integrated into the Company's operations or
that any acquired business will perform as expected. Failure of the Company to
implement its expansion and growth strategy successfully would have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
RISKS RELATED TO LOCAL SERVICES STRATEGY
 
  The Company plans to enter the newly created competitive local
telecommunications services industry. The local dial tone services market has
only recently been opened to competition through the passage of the
Telecommunications Act of 1996 (the "Telecommunications Act") and subsequent
state and Federal regulatory actions designed to implement the
Telecommunications Act. Regulatory bodies have not completed all actions
expected to be needed to implement local service competition, and there is
little experience under those decisions that have been made to date. The
Company will have to make significant operating and capital investments in
order to implement its local exchange services strategy. There are numerous
operating complexities associated with providing these services. The Company
will be required to develop new products, services and systems and will need
to develop new marketing initiatives and train its sales force in connection
with selling these services. The Company will also need to implement the
necessary billing and collecting systems for these services. The Company will
face significant competition from the Regional Bell Operating Companies, whose
core business is providing local dial tone service. The Regional Bell
Operating Companies, who currently are the dominant providers of services in
their markets, are expected to mount a significant competitive response to new
entrants in their markets such as the Company. The Company also will face
significant competitive product and pricing
 
                                      17
<PAGE>
 
pressures from other incumbent local exchange carriers and from other firms
seeking to compete in the local services market.
 
  The Company also expects that the addition of local service to its bundle of
telecommunications services will have an adverse impact on its gross margin
because the gross margin on the resale of local services through incumbent
local exchange carrier facilities is lower than the gross margin on the
Company's existing business. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Overview."
 
PRICING PRESSURES AND RISKS OF INDUSTRY OVER-CAPACITY
 
  The long distance transmission industry has generally been characterized by
over-capacity and declining prices since shortly after the AT&T divestiture in
1984. The Company believes that, in the last several years, increasing demand
has ameliorated the over-capacity and that pricing pressure has been reduced.
However, the Company anticipates that prices for its Carriers' Carrier
Services will continue to decline over the next several years. The Company is
aware that certain long distance carriers are expanding their capacity and
believes that other long distance carriers, as well as potential new entrants
to the industry, are constructing new fiber optic and other long distance
transmission networks in the southern United States. Since the cost of the
actual fiber (as opposed to construction costs) is a relatively small portion
of the cost of building new transmission lines, persons building such lines
are likely to install fiber that provides substantially more transmission
capacity than will be needed over the short or medium term. Further, recent
technological advances may greatly expand the capacity of existing and new
fiber optic cable. Although such technological advances may enable the Company
to increase its capacity, an increase in the capacity of the Company's
competitors could adversely affect the Company's business. If industry
capacity expansion results in capacity that exceeds overall demand along any
of the Company's routes, severe additional pricing pressure could develop. In
addition, strategic alliances or similar transactions, such as the long
distance capacity purchasing alliance among certain Regional Bell Operating
Companies announced in the spring of 1996, could result in additional pricing
pressure on long distance carriers. Furthermore, the marginal cost of carrying
an additional call over existing fiber optic cable is extremely low. As a
result, within a few years, there may be dramatic and substantial price
reductions. Such pricing pressure could have a material adverse effect on the
Company. In addition, the Federal Communications Commission (the "FCC") has
announced changes to its interstate access rules which may result in
additional pricing pressures. See "--Competition."
 
DEPENDENCE ON BILLING, CUSTOMER SERVICE AND INFORMATION SYSTEMS
   
  Sophisticated information and processing systems are vital to the Company's
growth and its ability to monitor costs, bill customers, provision customer
orders and achieve operating efficiencies. As the Company commences providing
dial tone and switched local access services, the need for enhanced billing
and information systems will increase significantly. The inability of the
Company to identify adequately all of its information and processing needs, or
to upgrade systems as necessary, could have a material adverse impact on the
ability of the Company to reach its objectives, on its financial condition and
results of operations and on its ability to pay interest and principal on the
Exchange Notes.     
 
DEPENDENCE ON RIGHTS OF WAY AND OTHER THIRD PARTY AGREEMENTS
 
  The Company has obtained easements, rights of way, franchises and licenses
from various private parties, including actual and potential competitors, and
local governments in order to construct and maintain its fiber optic network.
There can be no assurance that the Company will continue to have access to
existing rights of way and franchises after the expiration of such agreements.
If a franchise, license or lease agreement were terminated and the Company
were forced to remove or abandon a significant portion of its network, such
termination could have a material adverse effect on the Company.
 
 
                                      18

REGULATION
 
  The Company is required to obtain certain authorizations from the FCC and
state public utility commissions ("PUCs") to offer certain of its
telecommunications services, as well as file tariffs for many of its services.
To date the Company has not experienced significant difficulties in receiving
certification, maintaining tariffs, or otherwise complying with its regulatory
obligations. The Company will face new obligations arising out of the
Telecommunications Act as it begins to enter the local telephone market. It
also is likely that state PUCs will regulate the local telephone services
offered by the Company and other competitive local exchange carriers more
heavily than competitive long distance services have been regulated in the
past. Because the FCC and the states have yet to adopt many of the rules and
policies necessary to implement the Telecommunications Act, or to respond to
other related local telephone competition issues, it is uncertain how
burdensome these requirements will be for the Company.
 
  Although the Company entered into the Interconnection Agreement pursuant to
which it will obtain wholesale local services and access to unbundled network
elements from BellSouth, the terms of the Interconnection Agreement are
subject to the approval of the PUCs regulating the Company's markets. Such
approval has been received from the PUCs of Alabama, Georgia, Kentucky,
Louisiana, Mississippi, North Carolina and South Carolina and is pending in
Florida and Tennessee.
          
  In addition, the Company's plans to provide local telephone service are
heavily dependent upon implementation of provisions of the Telecommunications
Act. The Telecommunications Act preempted state and local laws to the extent
that they prohibited local telephone competition, and imposed a variety of new
duties on incumbent local exchange carriers intended to advance such
competition, including the duty to negotiate in good faith with competitors
requesting interconnection to the incumbent local exchange carrier's network.
However, negotiations with incumbent local exchange carriers have sometimes
involved considerable delays and the resulting negotiated agreements may not
necessarily be obtained on terms and conditions that are acceptable to the
Company. In such instances, the Company may petition the proper state
regulatory agency to arbitrate disputed issues. There can be no assurance that
the Company will be able to negotiate acceptable new interconnection
agreements with incumbent local exchange carriers or that if state regulatory
authorities impose terms and conditions on the parties in arbitration, such
terms will be acceptable to the Company. On August 8, 1996, the FCC adopted
rules and policies implementing the local competition provisions of the
Telecommunications Act, which rules, in general, were considered favorable to
new competitive entrants, but those rules have not been fully implemented. The
FCC's rules were challenged in the federal courts by GTE, Regional Bell
Operating Companies, large independent incumbent local exchange carriers and
state regulatory commissions. On October 15, 1996, the U.S. Court of Appeals
for the Eighth Circuit issued a stay of the implementation of certain of the
FCC's rules and on July 18, 1997, the Court issued its decision finding that
the FCC lacked statutory authority under the Telecommunications Act for
certain of its rules. In particular, the Court found that the FCC was not
empowered to establish the pricing standards governing unbundled local network
elements or wholesale local services of the incumbent local exchange carriers.
The Court also struck down other FCC rules, including one that would have
enabled new entrants to "pick and choose" from provisions of established
interconnection agreements between the incumbent local exchange carriers and
other carriers. The Court rejected certain other objections to the FCC rules
brought by the incumbent local exchange carriers or the states, including
challenges to the FCC's definition of unbundled elements, and to the FCC's
rules allowing new competitors to create their own networks by combining
incumbent local exchange carrier network elements together without adding
additional facilities of their own. The overall impact of the Court's decision
is to materially reduce the role of the FCC in fostering local competition,
including its ability to take enforcement action if the Telecommunications Act
is violated, and increase the role of state utility commissions. The FCC has
indicated that it will ask the Supreme Court to review the Court's decision.
Meanwhile, state commissions have asserted that they will be active in
promoting local telephone competition using the authority they have under the
ruling, lessening the significance of the reduced FCC role. At this time the
impact of the Court's decision cannot be evaluated, but there can be no
assurance that the Court decision and related developments will not have a
materially adverse effect on the Company. Furthermore, other FCC rules related
to local     
 
                                      19
<PAGE>
 
   
telephone competition remain the subject of legal challenges, and there can be
no assurance that decisions affecting those rules will not be adverse to
companies seeking to enter the local telephone market.     
 
  The Telecommunications Act also creates the foundation for increased
competition in the long distance market from the incumbent local exchange
carriers, which could affect the successful implementation of the Company's
business plans. For example, certain provisions eliminate previous
prohibitions on the provision of interLATA long distance services (both retail
and carriers' carrier) by the Regional Bell Operating Companies subject to
compliance by such companies with requirements set forth in the
Telecommunications Act and implemented by the FCC. The Company could be
adversely affected if the Regional Bell Operating Companies (and particularly
BellSouth) are allowed to provide wireline interLATA long distance services
within their own regions before local competition is established. In a related
development, the FCC is considering proposed 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 are
expected to consider incumbent local exchange carrier requests for similar
regulatory relief with respect to intrastate services. Such flexibility is
likely to come first for services offered in the business market. Any pricing
flexibility or other significant deregulation of the incumbent local exchange
carriers could have a material adverse effect on the Company. See "Business--
Regulation."
 
COMPETITION
   
  The Company operates in a highly competitive environment, and the level of
competition, particularly with respect to pricing, is increasing. Local
telephone and intraLATA long distance services substantially similar to those
expected to be offered by the Company are also offered by the incumbent local
exchange carriers serving the markets that the Company plans to serve.
BellSouth is the incumbent local exchange carrier and a particularly strong
competitor in most of the markets to be served by the Company. BellSouth and
other incumbent local exchange carriers already have relationships with every
customer and have the potential to subsidize services of the type offered by
the Company from service revenues not subject to effective competition, which
could result in even more intense price competition. The Company competes with
long distance carriers in the provision of interLATA long distance Retail and
Carriers' Carrier Services. The interLATA long distance market consists of
three major competitors (AT&T, MCI and Sprint) but other companies operate or
are building networks in the southern United States and other geographic
areas. Other competitors of the Company in the Retail and Carriers' Carrier
Services markets are likely to include Regional Bell Operating Companies
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. In addition, the Company competes with direct marketers, equipment
vendors and installers, and telecommunications management companies with
respect to certain portions of its business. Many of the Company's existing
and potential competitors have financial, technical and other resources and
customer bases and name recognition far greater than those of the Company. The
long distance business is extremely competitive and prices have declined
substantially in recent years and are expected to continue to decline, which
will adversely affect the Company's gross margins as a percentage of revenues.
The FCC recently announced changes to its interstate access rules that will
reduce per-minute access charges and substitute new per-line flat-rate monthly
charges. These actions are expected to reduce access rates. AT&T has committed
to reduce its long distance rates to reflect access cost reductions, and other
competitors of the Company are likely to make similar reductions. In such
event, the Company may need to reduce its rates to respond to competitive
pressures. See "--Dependence on Incumbent Local Exchange Carriers" and
"Business--Regulation."     
   
  The Telecommunications Act, other recent state legislative actions, and
current federal and state regulatory initiatives provide increased business
opportunities for the Company by removing or substantially reducing certain
barriers to local exchange competition. However, these new competitive
opportunities are expected to be accompanied by new competitive opportunities
for the incumbent local exchange carriers. It is also expected that increased
local competition will result in increased pricing flexibility for, and
relaxation of regulatory oversight of, the incumbent local exchange carriers.
If the incumbent local exchange carriers are permitted to engage in increased
volume and discount pricing practices or charge competitive local exchange
carriers increased fees for     
 
                                      20
<PAGE>
 
interconnection to their networks, or if the incumbent local exchange carriers
seek to delay implementation of interconnection by competitors to their
networks, the Company's results of operations and financial condition could be
adversely affected. There can be no assurance that the Company will be able to
achieve or maintain adequate market share or revenues, or compete effectively
in any of its markets.
 
  In addition, a continuing trend toward business combinations and strategic
alliances in the telecommunications industry may further enhance competition.
For example, the national long distance carrier WorldCom acquired MFS
Communications Company, Inc., a competitive local exchange carrier, in
December 1996. In November 1996, British Telecommunications plc, an
international telecommunications company, announced its agreement to acquire
MCI. In March 1997, BellSouth and International Business Machines Corporation
("IBM") announced an alliance to provide Internet and Intranet services to
businesses in the southern United States. These types of strategic alliances
could put the Company at a significant competitive disadvantage.
   
  The Company will face competition in the markets in which it operates from
one or more competitive local exchange carriers operating fiber optic
networks, in some cases in conjunction with the local cable television
operator. One of the primary purposes of the Telecommunications Act is to
promote competition, particularly in the local telephone market. AT&T, MCI,
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 develop. BellSouth has
announced plans to provide competitive local service in areas of its region
where it is not the incumbent local exchange carrier.     
 
  To complement its telecommunications services offerings, the Company offers
data transmission services. The data transmission business is extremely
competitive and prices have declined substantially in recent years and are
expected to continue to decline.
 
  The recent World Trade Organization ("WTO") agreement on basic
telecommunications services could increase the level of competition faced by
the Company. Under this agreement, the United States and other members of the
WTO committed themselves to opening their telecommunications markets to
competition and foreign ownership and to adopting regulatory measures to
protect against anticompetitive behavior by dominant telephone companies
effective as early as January 1, 1998.
 
  The Company also believes that providers of wireless services increasingly
will offer, in addition to products that supplement a customer's wireline
communications (similar to cellular telephone services in use today), wireline
replacement products that may result in wireless services becoming the
customer's primary mode of communication. For example, AT&T recently announced
plans to offer local services using a new wireless technology. AT&T's proposed
wireless system would link residential and business telephones via radio waves
to the AT&T network. If successful, this new service could further enhance
AT&T's ability to market, on a nationwide basis, "one-stop" telecommunications
services. Competition with providers of wireless telecommunications services
may be intense. Many of the Company's potential wireless competitors have
substantially greater financial, technical, marketing, sales, manufacturing
and distribution resources than those of the Company.
 
DEPENDENCE ON INCUMBENT LOCAL EXCHANGE CARRIERS
   
  The Company is dependent on incumbent local exchange carriers to provide
access service for the origination and termination of its 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. On May 7, 1997, the FCC adopted changes to its
interstate access rules that, among other things, will reduce per-minute
access charges and substitute 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. The
impact of these changes on the Company or its competitors is not yet clear.
The Company could be adversely affected if it does not experience access cost
reductions proportionally equivalent to those of its competitors. See
"Business--Regulation."     
 
                                      21
<PAGE>
 
  The Company also generally will be dependent on incumbent local exchange
carriers for provision of local telephone service through access to local
loops, termination service and, in some markets, central office switches of
such carriers. In addition, the Company intends to obtain the local telephone
services of the incumbent local exchange carriers on a wholesale basis and
resell that service to end users, particularly in the early stages of its
local telephone service business.
   
  Any successful effort by the incumbent local exchange carriers to deny or
substantially limit the Company's access to the incumbent local exchange
carrier's network elements or wholesale services would have a material adverse
effect on the Company's ability to provide local telephone services. Although
the Telecommunications Act imposes interconnection obligations on incumbent
local exchange carriers, there can be no assurance that the Company will be
able to obtain access to such network elements or services at rates, and on
terms and conditions, that permit the Company to offer local services at rates
that are both profitable and competitive. As noted above, the Eighth Circuit
Court of Appeals recently struck down certain FCC rules intended to govern
such rates, terms and conditions. See "Risk Factors--Regulation." The result
of this decision is to give state utility commissions a significantly larger
role in implementing the Telecommunications Act. It is uncertain whether such
commissions will adopt and enforce rules or take other actions that will
permit new carriers to have economical use of incumbent local exchange carrier
networks and facilities. The Interconnection Agreement currently allows the
Company to provide local service on a resale basis or by purchasing all
unbundled network elements required to provide local service on a facilities
bases, without using Company-owned facilities. The terms of the
Interconnection Agreement, including interim pricing terms agreed to by the
Company and BellSouth, have been approved by state regulatory authorities in
most states, although they remain subject to review and modification by such
authorities. In addition, the Interconnection Agreement does not resolve all
operational issues, particularly those relating to the collocation of the
Company's equipment with that of BellSouth. The Company and BellSouth are
continuing to negotiate to resolve such issues. Many issues relevant to the
terms and conditions by which competitors may use the incumbent local exchange
carrier network and wholesale services remain to be resolved. For example,
BellSouth and certain other incumbent local exchange carriers have taken the
position that when a carrier seeking to provide local service obtains all
necessary elements (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 the service to the
customers served on that basis. Although the Court decision appears to reject
this position, further legal challenges are likely and important issues
related to this form of interconnection remain open. Similarly, substantial
problems have arisen with respect to the operational 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 the Company to provide local service to customers on a timely
and competitive basis. The FCC has recently created a task force to examine
problems that have slowed the development of local telephone competition. See
"Business--Regulation" and "Services and Facilities."     
       
DEPENDENCE ON CERTAIN CUSTOMERS
   
  For the year ended December 31, 1996 and the six months ended June 30, 1997,
giving effect to the Reorganization, the Company's two largest Carriers'
Carrier customers would together have accounted for approximately 15% and 12%,
respectively, of the Company's combined pro forma revenues. For the six months
ended June 30, 1997, the Company's five largest Retail Services customers
would have represented an aggregate of approximately 10% of the Company's
combined pro forma revenues. The Company's customers generally use more than
one service provider and may reduce their use of the Company's services and
switch to other providers without incurring significant expense. The Company's
agreements with its customers generally provide that the customer may
terminate service without penalty in the event of certain outages in service
and for certain other defined causes. Although, as of June 30, 1997, on a pro
forma basis, the Company's Carriers' Carrier business had remaining future
long-term contract commitments totaling approximately $75.8 million, some of
such contractual commitments provide that, if the customer is offered lower
pricing with respect to any circuit by another carrier, the customer's
commitment to the Company will be reduced to the extent the Company does not
match the price for such circuit and the customer purchases such circuit from
the other carrier. There can be no assurance that the Company will be able to
retain its customers. The loss of or a significant decrease of business from
any of its largest customers would have a material adverse effect on the
Company's business, results of operations and financial condition.     
 
                                      22
<PAGE>
 
RISK OF RAPID TECHNOLOGICAL CHANGES
 
  The telecommunications industry is subject to rapid and significant changes
in technology. Although the Company believes that, for the foreseeable future,
these changes will neither materially affect the continued use of its fiber
optic network, digital switches and transmission equipment, nor materially
hinder its ability to acquire necessary technologies, the effect of
technological changes on the business of the Company, such as changes relating
to emerging wireline (including fiber optic) and wireless (including
broadband) transmission technologies, cannot be predicted. In addition, the
Company may be required to select in advance one technology over another, but
it will be impossible to predict with any certainty, at the time the Company
is required to make its investment, which technology will prove to be the most
economic, efficient or capable of attracting customer usage.
 
DEPENDENCE ON NETWORK INFRASTRUCTURE
   
  The Company has entered into marketing and management agreements with three
southern public utility companies to sell long-haul private line services on a
commission basis on the fiber optic networks owned by these companies.
Pursuant to these agreements, which have remaining terms ranging from five to
eight years, the Company generally earns a commission based upon a percentage
of the gross revenues generated by the sale of capacity on the utility's
networks. By interconnecting the Company's owned network to these other
networks owned by the public utilities, and by marketing and selling capacity
on such networks to the Company's customers, the Company has effectively
extended its network with minimal capital expenditure. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Overview." The Company also has a buy-sell agreement with Carolinas Fibernet,
LLC, which manages fiber optic facilities in North Carolina and South
Carolina. Although the Company does not believe that any of these agreements
will be terminated in the near future, cancellation or non-renewal of any of
such agreements could materially adversely affect the Company's business. In
addition, two of the Company's three agreements with public utility companies
are nonexclusive, and the Company 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 the Company could adversely affect the
Company. To the extent the Company is unable to establish similar arrangements
in new markets, it may be required to make additional capital expenditures to
extend its fiber network.     
 
  The Company's business also could be materially adversely affected by a
cable cut or equipment failure in the Company's fiber optic network. Although
the Company has implemented electronic redundancy throughout its network,
which enables traffic to be rerouted to another fiber in the same fiber sheath
in the event of a partial fiber cut or electronics failure, a substantial
portion of the Company's owned and managed fiber optic network is not
protected in the event of a total cable cut.
 
HOLDING COMPANY STRUCTURE; PRIORITY OF SECURED DEBT
   
  The Company is a holding company with no direct operations and no
significant assets other than the stock of its subsidiaries. The Company is
dependent on the cash flows of its subsidiaries to meet its obligations,
including the payment of interest and principal on the Exchange Notes. The
Company's subsidiaries are separate legal entities that have no obligation to
pay any amounts due pursuant to the Exchange Notes or to make any funds
available therefor, whether by dividends, loans or other payments. Because the
Company's subsidiaries will not guarantee the payment of the principal or
interest on the Exchange Notes, any right of the Company to receive assets of
any of its subsidiaries upon its liquidation or reorganization (and the
consequent right of holders of the Exchange Notes to participate in the
distribution or realize proceeds from those assets) will be effectively
subordinated to the claims of the creditors of any such subsidiary (including
trade creditors and holders of indebtedness of such subsidiary), except if and
to the extent the Company is itself a creditor of such subsidiary, in which
case the claims of the Company would still be effectively subordinated to any
security interest in the assets of such subsidiary held by other creditors. As
of June 30, 1997, on a pro forma basis, giving effect to the Reorganization,
the subsidiaries of the Company had approximately $37.8 million of liabilities
(excluding     
 
                                      23
<PAGE>
 
   
intercompany payables), including approximately $14.4 million of indebtedness
(including capital leases). A subsidiary of the Company is expected to have up
to $100 million of availability under the Credit Facility, and each of the
other subsidiaries of the Company will be guarantors thereunder.     
 
  The Exchange Notes are unsecured (except with respect to the Pledged
Securities) and therefore will be effectively subordinated to any secured
indebtedness of the Company. The Indenture will permit the Company and its
subsidiaries to incur an unlimited amount of indebtedness to finance the
acquisition of equipment, inventory and network assets and to secure such
indebtedness, and up to $100 million of other secured indebtedness pursuant to
one or more credit facilities, including the Credit Facility. The Credit
Facility is expected to be secured by substantially all of the assets of the
Company's subsidiaries. Consequently, in the event of a bankruptcy,
liquidation, dissolution, reorganization or similar proceeding with respect to
the Company, such assets would be available to satisfy obligations of the
secured debt before any payment could be made on the Exchange Notes. In
addition, to the extent such assets did not satisfy in full the secured
indebtedness, the holders of such indebtedness would have a claim for any
shortfall that would be pari passu (or effectively senior if the indebtedness
were issued by a subsidiary) with the Exchange Notes. Accordingly, there may
only be a limited amount of assets available to satisfy any claims of the
holders of the Exchange Notes upon an acceleration of the Exchange Notes.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's business is currently managed by a small number of key
management and operating personnel. The Company does not have any employment
agreements with, nor does the Company 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 the Company. See "Management."
 
CONTROL BY ITC HOLDING COMPANY; CONFLICTS OF INTEREST
 
  The Company is authorized under its certificate of incorporation to issue
60,000,000 shares of Class A common stock (the "Class A Common Stock"), which
have one vote per share, and 30,000,000 shares of Class B common stock (the
"Class B Common Stock"), which have ten votes per share. ITC Holding owns
15,000,000 shares of Class B Common Stock, which constitute all of the
Company's issued and outstanding capital stock. Certain decisions concerning
the operations or financial structure of the Company may present conflicts of
interest between ITC Holding and the holders of the Exchange Notes. For
example, if the Company encounters financial difficulties or is unable to pay
its debts as they mature, the interests of ITC Holding might conflict with
those of the holders of the Exchange Notes. In addition, ITC Holding may have
an interest in pursuing acquisitions, divestitures, financings or other
transactions that, in its judgment, could enhance its equity investment in the
Company, even though such transactions might involve risk to the holders of
the Exchange Notes.
 
ABSENCE OF PUBLIC MARKET
 
  The Senior Notes have been designated for trading by qualified buyers in the
PORTAL Market. The Senior Notes have not been registered under the Securities
Act, however, and will continue to be subject to restrictions on
transferability to the extent that they are not exchanged for Exchange Notes.
Furthermore, the Exchange Offer will not be conditioned upon any minimum or
maximum aggregate principal amount of Senior Notes being tendered for
exchange. No assurance can be given as to the liquidity of the trading market
of the Senior Notes following the Exchange Offer.
 
  Although the Exchange Notes will generally be permitted to be resold or
otherwise transferred by the holders thereof (other than any holder that is
(i) an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act or (ii) a broker-dealer that acquired Senior Notes as a result
of market-making activities or other trading activities) without compliance
with the registration requirements under the Securities Act, the
 
                                      24
<PAGE>
 
Exchange Notes will constitute a new issue of securities for which there is
currently no established trading market. If a trading market does not develop
or is not maintained, holders of the Exchange Notes may experience difficulty
in reselling the Exchange Notes or may be unable to sell them at all. If a
market for the Exchange Notes develops, any such market may cease at any time.
If a public trading market develops for the Exchange Notes, future trading
prices of the Exchange Notes will depend on many factors, including, among
other things, prevailing interest rates, the market for similar securities,
the financial conditions and results of operations of the Company and other
factors beyond the control of the Company, including general economic
conditions. The Company does not intend to list the Exchange Notes on any
national securities exchange or to seek approval for quotation through any
automated quotation system. The Company has been advised by the Placement
Agents that following completion of the Exchange Offer, the Placement Agents
intend to make a market in the Exchange Notes. However, the Placement Agents
are not obligated to do so and any market-making activities with respect to
the Exchange Notes may be discontinued at any time without notice.
Accordingly, no assurance can be given that an active public or other market
will develop for the Exchange Notes or as to the liquidity of or the trading
market for the Exchange Notes.
 
  Notwithstanding the registration of the Exchange Notes in the Exchange
Offer, holders who are "affiliates" of the Company (within the meaning of Rule
405 under the Securities Act) may publicly offer for sale or resell the
Exchange Notes only in compliance with the provisions of Rule 144 under the
Securities Act or any other available exemptions under the Securities Act.
 
  Each broker-dealer that receives Exchange Notes for its own account in
exchange for Senior Notes, where such Senior Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. See "Plan of Distribution."
 
CONSEQUENCES OF A FAILURE TO EXCHANGE SENIOR NOTES
 
  The Senior Notes have not been registered under the Securities Act or any
state securities laws and therefore may not be offered, sold or otherwise
transferred except in compliance with the registration requirements of the
Securities Act and any other applicable securities laws, or pursuant to an
exemption therefrom or in a transaction not subject thereto, and in each case
in compliance with certain other conditions and restrictions. Senior Notes
that remain outstanding after consummation of the Exchange Offer will continue
to bear a legend reflecting such restrictions on transfer. In addition, upon
consummation of the Exchange Offer, holders of Senior Notes that remain
outstanding will not be entitled to any rights to have such Senior Notes
registered under the Securities Act, except under certain limited
circumstances. The Company does not intend to register under the Securities
Act any Senior Notes that remain outstanding after consummation of the
Exchange Offer. See "The Exchange Offer." To the extent that Senior Notes are
not tendered and accepted in the Exchange Offer, a holder's ability to sell
such Senior Notes could be adversely affected.
 
EXCHANGE OFFER PROCEDURES
 
  Issuance of the Exchange Notes in exchange for Senior Notes pursuant to the
Exchange Offer will be made only after a timely receipt by the Exchange Agent
of (i) such Senior Notes or a book-entry confirmation of a book-entry transfer
of the Senior Notes into the Exchange Agent's account at The Depository Trust
Company ("DTC"); (ii) the Letter of Transmittal (or a facsimile thereof),
properly completed and duly executed, with any required signature guarantees;
and (iii) any other documents required by the Letter of Transmittal. Holders
of the Senior Notes desiring to tender such Senior Notes in exchange for
Exchange Notes should allow sufficient time to ensure timely delivery. The
Company and the Exchange Agent are under no duty to give notification of
defects or irregularities with respect to the tenders of Senior Notes for
exchange. See "The Exchange Offer."

                              THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
  In connection with the sale of the Senior Notes, the Company entered into
the Registration Rights Agreement with the Placement Agents, pursuant to which
the Company agreed to file and to use its best efforts to cause to become
effective with the Commission a registration statement with respect to the
exchange of the Senior Notes for Exchange Notes with terms identical in all
material respects to the terms of the Senior Notes. A copy of the Registration
Rights Agreement has been filed as an exhibit to the Registration Statement of
which this Prospectus is a part (the "Registration Statement"). The Exchange
Offer is being made to satisfy the contractual obligations of the Company
under the Registration Rights Agreement.
 
  By tendering Senior Notes in exchange for Exchange Notes, each holder will
represent to the Company that: (i) any Exchange Notes to be received by such
holder will be acquired in the ordinary course of such holder's business; (ii)
such holder has no arrangement or understanding with any person to participate
in a distribution (within the meaning of the Securities Act) of the Exchange
Notes; (iii) such holder is not an "affiliate" of the Company (within the
meaning of Rule 405 under the Securities Act), or if such holder is an
affiliate, that such holder will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable; (iv)
such holder has full power and authority to tender, exchange, sell, assign and
transfer the tendered Senior Notes; (v) the Company will acquire good,
marketable and unencumbered title to the tendered Senior Notes, free and clear
of all liens, restrictions, charges and encumbrances; and (vi) the Senior
Notes tendered for exchange are not subject to any adverse claims or proxies.
Each tendering holder also will warrant and agree that such holder will, upon
request, execute and deliver any additional documents deemed by the Company or
the Exchange Agent to be necessary or desirable to complete the exchange,
sale, assignment, and transfer of the Senior Notes tendered pursuant to the
Exchange Offer. Each broker-dealer that receives Exchange Notes for its own
account in exchange for Senior Notes, where such Senior Notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. See "Plan of Distribution."
 
  The Exchange Offer is not being made to, nor will the Company accept tenders
for exchange from, holders of Senior Notes in any jurisdiction in which the
Exchange Offer or the acceptance thereof would not be in compliance with the
securities or blue sky laws of such jurisdiction.
 
  Unless the context requires otherwise, the term "holder" with respect to the
Exchange Offer means any person in whose name the Senior Notes are registered
on the books of the Company or any other person who has obtained a properly
completed bond power from the registered holder, or any participant in DTC
whose name appears on a security position listing as a holder of Senior Notes
(which, for purposes of the Exchange Offer, include beneficial interests in
the Senior Notes held by direct or indirect participants in DTC and Senior
Notes held in definitive form).
 
TERMS OF THE EXCHANGE OFFER
 
  The Company hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal, to
exchange $1,000 principal amount of Exchange Notes for each $1,000 principal
amount of Senior Notes properly tendered prior to the Expiration Date and not
properly withdrawn in accordance with the procedures described below. Holders
may tender their Senior Notes in whole or in part in integral multiples of
$1,000 principal amount.
 
  The form and terms of the Exchange Notes will be the same as the form and
terms of the Senior Notes except that (i) the Exchange Notes will have been
registered under the Securities Act and therefore will not be subject to
certain restrictions on transfer applicable to the Senior Notes and (ii)
holders of the Exchange Notes will not be entitled to certain rights of
holders of the Senior Notes under the Registration Rights Agreement. The
 
                                      26
<PAGE>
 
Exchange Notes will evidence the same indebtedness as the Senior Notes (which
they will replace) and will be issued pursuant to, and entitled to the
benefits of, the Indenture.
 
  The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Senior Notes being tendered for exchange. The Company reserves the
right in its sole discretion to purchase or make offers for any Senior Notes
that remain outstanding after the Expiration Date or, as set forth under "--
Conditions to the Exchange Offer," to terminate the Exchange Offer and, to the
extent permitted by applicable law, purchase Senior Notes in the open market,
in privately negotiated transactions or otherwise. The terms of any such
purchases or offers could differ from the terms of the Exchange Offer. As of
the date of this Prospectus,$200 million aggregate principal amount of Senior
Notes is outstanding.
 
  Holders of Senior Notes do not have any appraisal or dissenters' rights in
connection with the Exchange Offer. Senior Notes that are not tendered, or are
tendered but not accepted, in connection with the Exchange Offer will remain
outstanding and continue to accrue interest in accordance with their terms,
but will not retain any rights under the Registration Rights Agreement. See
"Risk Factors--Consequences of a Failure to Exchange Senior Notes."
 
  If any tendered Senior Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted Senior Notes will be returned,
without expense, to the tendering holder thereof promptly after the Expiration
Date.
 
  Holders who tender Senior Notes in connection with the Exchange Offer will
not be required to pay brokerage commissions or fees or, subject to the
instructions in the Letter of Transmittal, transfer taxes with respect to the
exchange of Senior Notes in connection with the Exchange Offer. The Company
will pay all charges and expenses, other than certain applicable taxes
described below, in connection with the Exchange Offer. See "--Fees and
Expenses."
 
  THE BOARD OF DIRECTORS OF THE COMPANY MAKES NO RECOMMENDATION TO HOLDERS OF
SENIOR NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY
PORTION OF THEIR SENIOR NOTES PURSUANT TO THE EXCHANGE OFFER. IN ADDITION, NO
ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF SENIOR
NOTES MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE EXCHANGE
OFFER AND, IF SO, THE AGGREGATE AMOUNT OF SENIOR NOTES TO TENDER AFTER READING
THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR
ADVISERS, IF ANY, BASED ON THEIR FINANCIAL POSITION AND REQUIREMENTS.
 
EXPIRATION DATE; EXTENSIONS, AMENDMENTS
 
  The term "Expiration Date" means 5:00 p.m., New York City time, on      ,
1997 unless the Exchange Offer is extended by the Company (in which case the
term "Expiration Date" shall mean the latest date and time to which the
Exchange Offer is extended).
 
  The Company expressly reserves the right in its sole and absolute
discretion, subject to applicable law, at any time and from time to time, (i)
to delay the acceptance of the Senior Notes for exchange; (ii) to terminate
the Exchange Offer (whether or not any Senior Notes have theretofore been
accepted for exchange) if the Company determines, in its sole and absolute
discretion, that any of the events or conditions referred to under "--
Conditions to the Exchange Offer" has occurred or exists or has not been
satisfied; (iii) to extend the Expiration Date of the Exchange Offer and
retain all Senior Notes tendered pursuant to the Exchange Offer, subject,
however, to the right of holders of Senior Notes to withdraw their tendered
Senior Notes as described under "--Withdrawal Rights;" and (iv) to waive any
condition or otherwise amend the terms of the Exchange Offer in any respect
(whether or not any Senior Notes have theretofore been accepted for exchange).
If the Exchange Offer is amended in a manner determined by the Company to
constitute a material change, or if the Company waives a material condition of
the Exchange Offer, the Company will promptly disclose such amendment by means
of a prospectus supplement that will be distributed to the registered holders
of the Senior
 
                                      27
<PAGE>
 
Notes, and the Company will extend the Exchange Offer to the extent required
by Rule 14e-1 under the Exchange Act.
 
  Any such delay in acceptance, termination, extension or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent (any
such oral notice to be promptly confirmed in writing) and by making a public
announcement thereof, and such announcement in the case of an extension will
be made no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled Expiration Date. Without limiting the manner in
which the Company may choose to make any public announcement, and subject to
applicable laws, the Company shall have no obligation to publish, advertise or
otherwise communicate any such public announcement other than by issuing a
release to an appropriate news agency.
 
ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF EXCHANGE NOTES
 
  Upon the terms and subject to the conditions of the Exchange Offer, the
Company will exchange, and will issue to the Exchange Agent, Exchange Notes
for Senior Notes validly tendered and not withdrawn (pursuant to the
withdrawal rights described under "--Withdrawal Rights") promptly after the
Expiration Date.
 
  In all cases, delivery of Exchange Notes in exchange for Senior Notes
tendered and accepted for exchange pursuant to the Exchange Offer will be made
only after timely receipt by the Exchange Agent of (i) Senior Notes or a book-
entry confirmation of a book-entry transfer of Senior Notes into the Exchange
Agent's account at DTC; (ii) the Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees;
and (iii) any other documents required by the Letter of Transmittal.
Accordingly, the delivery of Exchange Notes might not be made to all tendering
holders at the same time, and will depend upon when Senior Notes, book-entry
confirmations with respect to Senior Notes and other required documents are
received by the Exchange Agent.
 
  The term "book-entry confirmation" means a timely confirmation of a book-
entry transfer of Senior Notes into the Exchange Agent's account at DTC.
 
  Subject to the terms and conditions of the Exchange Offer, the Company will
be deemed to have accepted for exchange, and thereby exchanged, Senior Notes
validly tendered and not withdrawn as, if and when the Company gives oral or
written notice to the Exchange Agent (any such oral notice to be promptly
confirmed in writing) of the Company's acceptance of such Senior Notes for
exchange pursuant to the Exchange Offer. The Company's acceptance for exchange
of Senior Notes tendered pursuant to any of the procedures described above
will constitute a binding agreement between the tendering holder and the
Company upon the terms and subject to the conditions of the Exchange Offer.
The Exchange Agent will act as agent for the Company for the purpose of
receiving tenders of Senior Notes, Letters of Transmittal and related
documents, and as agent for tendering holders for the purpose of receiving
Senior Notes, Letters of Transmittal and related documents and transmitting
Exchange Notes to holders who validly tendered Senior Notes. Such exchange
will be made promptly after the Expiration Date. If for any reason whatsoever
the acceptance for exchange or the exchange of any Senior Notes tendered
pursuant to the Exchange Offer is delayed (whether before or after the
Company's acceptance for exchange of Senior Notes), or the Company extends the
Exchange Offer or is unable to accept for exchange or exchange Senior Notes
tendered pursuant to the Exchange Offer, then, without prejudice to the
Company's rights set forth herein, the Exchange Agent may, nevertheless, on
behalf of the Company and subject to Rule 14e-1(c) under the Exchange Act,
retain tendered Senior Notes and such Senior Notes may not be withdrawn except
to the extent tendering holders are entitled to withdrawal rights as described
under "--Withdrawal Rights."
 
PROCEDURES FOR TENDERING SENIOR NOTES
 
  Valid Tender. Except as set forth below, in order for Senior Notes to be
validly tendered pursuant to the Exchange Offer, either (i) (a) a properly
completed and duly executed Letter of Transmittal (or facsimile thereof), with
any required signature guarantees and any other required documents, must be
received by the Exchange Agent at the address set forth under "--Exchange
Agent" prior to the Expiration Date and (b) tendered Senior
 
                                      28
<PAGE>
 
Notes must be received by the Exchange Agent, or such Senior Notes must be
tendered pursuant to the procedures for book-entry transfer set forth below
and a book-entry confirmation must be received by the Exchange Agent, in each
case prior to the Expiration Date, or (ii) the guaranteed delivery procedures
set forth below must be complied with.
 
  If less than all of the Senior Notes held by a holder are tendered by such
holder, such holder should fill in the amount of Senior Notes being tendered
in the appropriate box on the Letter of Transmittal. The entire amount of
Senior Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.
 
  If any Letter of Transmittal, endorsement, bond power, power of attorney, or
any other document required by the Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and unless waived by the Company,
evidence satisfactory to the Company, in its sole discretion, of such person's
authority to so act must be submitted.
 
  Any beneficial owner of Senior Notes that are held by or registered in the
name of a broker, dealer, commercial bank, trust company or other nominee or
custodian is urged to contact such entity promptly if such beneficial holder
wishes to participate in the Exchange Offer.
 
  THE METHOD OF DELIVERY OF SENIOR NOTES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER, AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS
USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY AND PROPER INSURANCE SHOULD BE
OBTAINED. NO LETTER OF TRANSMITTAL OR SENIOR NOTES SHOULD BE SENT TO THE
COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THESE TRANSACTIONS FOR SUCH
HOLDERS.
 
  Book-Entry Transfer. The Exchange Agent will make a request to establish an
account with respect to the Senior Notes at DTC for purposes of the Exchange
Offer within two business days after the date of this Prospectus. Any
financial institution that is a participant in DTC's book-entry transfer
facility system may make a book-entry delivery of the Senior Notes by causing
DTC to transfer such Senior Notes into the Exchange Agent's account at DTC in
accordance with DTC's procedures for transfers. However, although delivery of
Senior Notes may be effected through book-entry transfer into the Exchange
Agent's account at DTC, the Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees
and any other required documents, must in any case be delivered to and
received by the Exchange Agent at its address set forth under "--Exchange
Agent" prior to the Expiration Date, or the guaranteed delivery procedure set
forth below must be complied with.
 
  DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE
AGENT.
 
  Signature Guarantees. Certificates for Senior Notes need not be endorsed and
signature guarantees on a Letter of Transmittal or a notice of withdrawal, as
the case may be, are unnecessary unless (a) a certificate for Senior Notes is
registered in a name other than that of the person surrendering the
certificate or (b) a registered holder completes the box entitled "Special
Issuance Instructions" or "Special Delivery Instructions" in the Letter of
Transmittal. In the case of (a) or (b) above, such certificates for Senior
Notes must be duly endorsed or accompanied by a properly executed bond power,
with the endorsement or signature on the bond power and on the Letter of
Transmittal or the notice of withdrawal, as the case may be, guaranteed by a
firm or other entity identified in Rule 17Ad-15 under the Exchange Act as an
"eligible guarantor institution," including (as such terms are defined
therein) (i) a bank; (ii) a broker, dealer, municipal securities broker or
dealer or government securities broker or dealer; (iii) a credit union; (iv) a
national securities exchange, registered securities association
 
                                      29
<PAGE>
 
or clearing agency; or (v) a savings association that is a participant in a
Securities Transfer Association (each an "Eligible Institution"), unless
surrendered on behalf of such Eligible Institution. See Instructions 2 and 5
to the Letter of Transmittal.
 
  Guaranteed Delivery. If a holder desires to tender Senior Notes pursuant to
the Exchange Offer and the certificates for such Senior Notes are not
immediately available or time will not permit all required documents to reach
the Exchange Agent before the Expiration Date, or the procedures for book-
entry transfer cannot be completed on a timely basis, such Senior Notes may
nevertheless be tendered, provided that all of the following guaranteed
delivery procedures are complied with:
 
    (i) such tenders are made by or through an Eligible Institution;
 
    (ii) prior to the Expiration Date, the Exchange Agent receives from such
  Eligible Institution a properly completed and duly executed Notice of
  Guaranteed Delivery, substantially in the form accompanying the Letter of
  Transmittal, setting forth the name and address of the holder of Senior
  Notes and the amount of Senior Notes tendered, stating that the tender is
  being made thereby and guaranteeing that within three New York Stock
  Exchange trading days after the date of execution of the Notice of
  Guaranteed Delivery, the certificates for all physically tendered Senior
  Notes, in proper form for transfer, or a book-entry confirmation, as the
  case may be, and any other documents required by the Letter of Transmittal
  will be deposited by the Eligible Institution with the Exchange Agent. The
  Notice of Guaranteed Delivery may be delivered by hand, or transmitted by
  facsimile or mail to the Exchange Agent and must include a guarantee by an
  Eligible Institution in the form set forth in the Notice of Guaranteed
  Delivery; and
 
    (iii) the certificates (or book-entry confirmation) representing all
  tendered Senior Notes, in proper form for transfer, together with a
  properly completed and duly executed Letter of Transmittal, with any
  required signature guarantees and any other documents required by the
  Letter of Transmittal, are received by the Exchange Agent within three New
  York Stock Exchange trading days after the date of execution of the Notice
  of Guaranteed Delivery.
 
  Determination of Validity. All questions as to the form of documents,
validity, eligibility (including time of receipt) and acceptance for exchange
of any tendered Senior Notes will be determined by the Company, in its sole
discretion, which determination shall be final and binding on all parties. The
Company reserves the absolute right, in its sole and absolute discretion, to
reject any and all tenders determined by it not to be in proper form or the
acceptance for exchange of which may, in the view of counsel to the Company,
be unlawful. The Company also reserves the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer as set
forth under "--Conditions to the Exchange Offer" or any defect or irregularity
in any tender of Senior Notes of any particular holder whether or not similar
defects or irregularities are waived in the case of other holders.
 
  The Company's interpretation of the terms and conditions of the Exchange
Offer (including the Letter of Transmittal and the instructions thereto) will
be final and binding on all parties. No tender of Senior Notes will be deemed
to have been validly made until all defects or irregularities with respect to
such tender have been cured or waived. Neither the Company, any affiliates or
assigns of the Company, the Exchange Agent or any other person shall be under
any duty to give any notification of any defects or irregularities in tenders
or incur any liability for failure to give any such notification.
 
RESALES OF EXCHANGE NOTES
 
  Based on interpretations by the staff of the Commission, as set forth in no-
action letters issued to third parties unrelated to the Company, the Company
believes that holders of Senior Notes (other than any holder that is (i) a
broker-dealer that acquired Senior Notes as a result of market-making
activities or other trading activities or (ii) an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act) who exchange their
Senior Notes for Exchange Notes pursuant to the Exchange Offer may offer for
resale, resell and otherwise transfer such Exchange Notes without compliance
with the registration and prospectus delivery provisions of the Securities
Act, provided that such Exchange Notes are acquired in the ordinary course of
such holders' business
 
                                      30
<PAGE>
 
and such holders have no arrangement or understanding with any person to
participate in a distribution (within the meaning of the Securities Act) of
such Exchange Notes. Any holder who tenders Senior Notes in the Exchange Offer
with the intention to participate, or for the purpose of participating, in a
distribution of the Exchange Notes or who is an affiliate of the Company may
not rely upon such interpretations by the staff of the Commission and, in the
absence of an exemption therefrom, must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
secondary resale transaction. Failure to comply with such requirements in such
instance may result in such holder incurring liabilities under the Securities
Act for which the holder is not indemnified by the Company. The staff of the
Commission has not considered the Exchange Offer in the context of a no-action
letter, and there can be no assurance that the staff of the Commission would
make a similar determination with respect to the Exchange Offer. Each broker-
dealer that receives Exchange Notes for its own account in exchange for Senior
Notes, where such Senior Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities, must acknowledge that
it will deliver a prospectus in connection with any resale of such Exchange
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. The Company has
agreed that, for a period not to exceed 180 days after the Expiration Date, it
will furnish additional copies of this Prospectus, as amended or supplemented,
to any broker-dealer that reasonably requests such documents for use in
connection with any such resale. See "Plan of Distribution."
 
WITHDRAWAL RIGHTS
 
  Except as otherwise provided herein, tenders of Senior Notes may be
withdrawn at any time prior to the Expiration Date.
 
  In order for a withdrawal to be effective, a written, telegraphic or
facsimile transmission of such notice of withdrawal must be timely received by
the Exchange Agent at its address set forth under "--Exchange Agent" prior to
the Expiration Date. Any such notice of withdrawal must specify the name of
the person who tendered the Senior Notes to be withdrawn, the aggregate
principal amount of Senior Notes to be withdrawn, and (if certificates for
such Senior Notes have been tendered) the name of the registered holder of the
Senior Notes as set forth on the Senior Notes, if different from that of the
person who tendered such Senior Notes. If certificates for Senior Notes have
been delivered or otherwise identified to the Exchange Agent, the notice of
withdrawal must specify the certificate number on the particular Senior Notes
to be withdrawn and the signature on the notice of withdrawal must be
guaranteed by an Eligible Institution, except in the case of Senior Notes
tendered for the account of an Eligible Institution. If Senior Notes have been
tendered pursuant to the procedures for book-entry transfer set forth in "--
Procedures for Tendering Senior Notes," the notice of withdrawal must specify
the name and number of the account at DTC to be credited with the withdrawal
of Senior Notes and must otherwise comply with the procedures of DTC.
Withdrawals of tenders of Senior Notes may not be rescinded. Senior Notes
properly withdrawn will not be deemed validly tendered for purposes of the
Exchange Offer, but may be retendered at any subsequent time prior to the
Expiration Date by following any of the procedures described above under "--
Procedures for Tendering Senior Notes."
 
  All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, which determination shall be final and binding on all
parties. Neither the Company, any affiliates of the Company, the Exchange
Agent or any other person shall be under any duty to give any notification of
any defects or irregularities in any notice of withdrawal or incur any
liability for failure to give any such notification. Any Senior Notes which
have been tendered but which are withdrawn will be returned to the holder
thereof promptly after withdrawal.
 
INTEREST ON THE EXCHANGE NOTES
 
  Interest on the Exchange Notes will accrue at the rate of 11% per annum and
will be payable in cash semi-annually on June 1 and December 1, of each year,
commencing December 1, 1997.
 
                                      31

CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other provisions of the Exchange Offer or any extension
of the Exchange Offer, the Company will not be required to accept for
exchange, or to exchange, any Senior Notes for any Exchange Notes, and may, at
any time and from time to time, terminate the Exchange Offer or waive any
conditions to or amend the Exchange Offer in any respect (whether or not any
Senior Notes have theretofore been accepted for exchange), if the Exchange
Offer is determined by the Company, in its sole and absolute discretion, to
violate applicable law or any applicable interpretation of the staff of the
Commission.
 
  If such waiver or amendment constitutes a material change to the Exchange
Offer, the Company will promptly disclose such waiver by means of a prospectus
supplement that will be distributed to the registered holders of the Senior
Notes, and the Company will extend the Exchange Offer to the extent required
by Rule 14e-1 under the Exchange Act.
 
CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
  The exchange of the Senior Notes for the Exchange Notes will not be a
taxable exchange for federal income tax purposes, and holders of Senior Notes
should not recognize any taxable gain or loss or any interest income as a
result of such exchange.

  The Company has not retained any dealer-manager or similar agent in
connection with the Exchange Offer and will not make any payments to brokers,
dealers or others soliciting acceptances of the Exchange Offer. The Company
has agreed to pay the Exchange Agent reasonable and customary fees for its
services and will reimburse it for its reasonable out-of-pocket expenses in
connection therewith. The Company will also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus and related documents
to the beneficial owners of Senior Notes, and in handling or tendering for
their customers.
 
  Holders who tender their Senior Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith, except that if Exchange Notes
are to be delivered to, or are to be issued in the name of, any person other
than the registered holder of the Senior Notes tendered, or if a transfer tax
is imposed for any reason other than the exchange of Senior Notes in
connection with the Exchange Offer, then the amount of any such transfer tax
(whether imposed on the registered holder or any other persons) will be
payable by the tendering holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with the Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
holder.

                            HISTORY OF THE COMPANY
   
  ITC/\DeltaCom was incorporated in Delaware in March 1997 as a wholly owned
subsidiary of ITC Holding to acquire and operate ITC Holding's Retail Services
and Carriers' Carrier Services businesses. The Company acquired such
businesses on July 25, 1997 in the Reorganization.     
 
BACKGROUND
   
  ITC Holding has provided operator and directory assistance services since
March 1992 through InterQuest. Carriers' Carrier Services have been offered
since late 1992 through Interstate FiberNet, a partnership originally formed
by ITC Holding (with a 49% interest) and SCANA (with a 51% interest). In
August 1994, ITC Holding acquired SCANA's interest in Interstate FiberNet
through Transmission II. Also in August 1994, ITC Holding and SCANA formed a
second partnership, Gulf States FiberNet, to construct and operate a fiber
optic route primarily between Atlanta, Georgia and Shreveport, Louisiana with
several supplemental spur routes. In the Gulf States Acquisition, ITC Holding
acquired SCANA's 64% partnership interest in Gulf States FiberNet and the
Georgia Fiber Assets, which included one customer contract representing $3.5
million in annual revenues through August 2001, the term of the contract.
Following the Gulf States Acquisition, ITC Holding contributed the remaining
64% interest in Gulf States FiberNet to Gulf States Transmission and the
Georgia Fiber Assets to Transmission. Members of the Company's 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 DeltaCom Acquisition, ITC Holding
entered the retail long distance business and acquired several fiber optic
routes within the state of 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, provides long
distance services to mid-sized businesses primarily in the state of Alabama.
In July 1996, DeltaCom purchased substantially all of the assets of the
Internet business of ViperNet, which provides Internet access, Web-hosting and
Web page development services to business customers.     
   
  The aggregate consideration paid by ITC Holding in the DeltaCom Acquisition
was approximately $71.4 million (of which $6.0 million consisted of ITC
Holding common stock). To finance the DeltaCom Acquisition and to refinance
existing DeltaCom debt, ITC Holding incurred approximately $74.0 million of
indebtedness, which was pushed down to the Company (the DeltaCom
Indebtedness). See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Effects of Accounting Standards." The
aggregate consideration paid by ITC Holding in the Gulf States Acquisition was
approximately $27.9 million, of which $10.0 million consisted of the SCANA
Note, which has been assumed by a subsidiary of the Company, and $17.9 million
consisted of ITC Holding preferred stock. If the Gulf States FiberNet business
achieves a specified performance target for 1997, SCANA will be entitled to
receive additional ITC Holding preferred stock. In connection with the Gulf
States Acquisition, Gulf States Transmission borrowed $41.6 million under the
Bridge Facility to refinance a project loan incurred by Gulf States FiberNet.
    
   
SENIOR NOTE OFFERING     
   
  On June 3, 1997, the Company completed the sale of $200 million principal
amount of Senior Notes in a private offering. The net proceeds to the Company
from the sale of the Senior notes were approximately $192.7 million, after
deducting the estimated underwriting discounts and commissions and other
expenses payable by the Company. Approximately $62.7 million of such net
proceeds are held by the Trustee as security for and to fund the first six
interest payments on the Senior Notes and the Exchange Notes. The remaining
net proceeds from the sale of the Senior Notes were released to the Company
upon consummation of the Reorganization.     
       
   
REORGANIZATION     
   
  On July 25, 1997, upon receipt of certain regulatory approvals and certain
other consents, ITC Holding contributed to the Company in the Reorganization
the businesses of Interstate FiberNet, Gulf States FiberNet, DeltaCom and
InterQuest. As a result of the Reorganization, the Company became the sole
stockholder of Interstate FiberNet, Inc. (formerly Transmission, Transmission
II, InterQuest and Interstate FiberNet), and Interstate FiberNet, Inc. became
the sole stockholder of Gulf States FiberNet and DeltaCom.

  The following chart reflects the organizational structure of the Company
following the Reorganization:

          -------------------------------  ---------------------------
   
  In connection with the Reorganization, approximately $31.0 million of the
DeltaCom Indebtedness was forgiven by ITC Holding and contributed to the
Company as additional equity. Following the Reorganization, the Company repaid
the remaining $43.0 million of the DeltaCom Indebtedness, accrued interest on
all $74.0 million of such indebtedness and the $41.6 million of indebtedness
outstanding under the Bridge Facility and accrued interest thereon with a
portion of the net proceeds from the Offering. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."     
       
                                USE OF PROCEEDS
   
  The Exchange Offer is intended to satisfy certain obligations of the Company
under the Registration Rights Agreement. The Company will not receive any
proceeds from the issuance of the Exchange Notes offered hereby. In
consideration for issuing the Exchange Notes as contemplated in this
Prospectus, the Company will receive, in exchange, an equal number of Senior
Notes in like principal amount. The form and terms of the Exchange Notes will
be identical in all material respects to the form and terms of the Senior
Notes, except as otherwise described herein under "The Exchange Offer--Terms
of the Exchange Offer."     
   
  The net proceeds to the Company from the sale of the Senior Notes were
approximately $192.7 million, after deducting the estimated underwriting
discounts and commissions and other expenses payable by the Company.
Approximately $62.7 million of such net proceeds are held by the Trustee as
security for and to fund the first six scheduled interest payments on the
Senior Notes and the Exchange Notes. The remaining net proceeds from the
Offering were released to the Company upon consummation of the Reorganization.
The Company applied approximately $94.3 million of such net proceeds to repay
outstanding indebtedness (plus accrued interest) of the Company and
approximately $5.3 million of such net proceeds to repay advances from ITC
Holding used by the Company for capital expenditures. The Company has applied
or intends to apply the remaining net proceeds released to the Company to fund
market expansion activities of the Company's telecommunications business,
including development and construction costs of the Company's fiber optic
network and its regional sales offices; and for additional working capital and
other general corporate purposes, including the funding of cash flow deficits
(after capital expenditures). See "Management's Discussion and Analysis of

  As part of its business strategy, the Company intends to continue to
evaluate potential acquisitions, joint ventures and strategic alliances in
areas such as wireline and wireless services, network construction and
infrastructure and Internet access. The Company has no definitive agreement
with respect to any acquisition, although from time to time it has discussions
with other companies and assesses opportunities on an on-going basis. A
portion of the net proceeds from the Offering may be used to fund any such
acquisitions, joint ventures and strategic alliances. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."

                     SELECTED FINANCIAL AND OPERATING DATA
   
  The following table sets forth selected financial and operating data for the
Company. The selected historical statements of operations data for each of the
years ended December 31, 1994, 1995 and 1996, and the selected historical
balance sheet data for the years then ended, have been derived from the
combined financial statements that have been audited by Arthur Andersen LLP,
independent public accountants. The selected historical statement of
operations data for the six months ended June 30, 1996 and 1997 have been
derived from the Company's unaudited combined financial statements and
include, in the opinion of management, all adjustments (consisting only of
normal recurring adjustments) necessary to present fairly the data for such
periods. Operating results for interim periods are not necessarily indicative
of results for the full fiscal year. The selected historical financial and
operating data should be read in conjunction with "Use of Proceeds," "Pro

(a) Through August 17, 1994, the Company owned a 49% interest in Interstate
    FiberNet and accounted for this investment under the equity method. On
    August 17, 1994, the Company purchased the remaining 51% interest in
    Interstate FiberNet from SCANA. Therefore, Interstate FiberNet's revenues
    and expenses have been included in the combined statement of operations
    data effective January 1, 1994, with the preacquisition earnings
    attributable to SCANA deducted to determine combined net income for 1994.
    See note 5 to the combined financial statements.
(b) Includes operations of InterQuest from March 1992 (date of inception).
(c) On August 17, 1994, the Company entered into the Gulf States FiberNet
    partnership with SCANA. The Company obtained a 36% general partnership
    interest, and the investment was accounted for under the equity method.
    See note 5 to the combined financial statements.
(d) On January 29, 1996, ITC Holding purchased DeltaCom. DeltaCom's results of
    operations are included in the historical statement of operations data
    since the date of acquisition. See note 13 to the combined financial
    statements.
   
(e) On March 27, 1997, the Company purchased the remaining 64% partnership
    interest in Gulf States FiberNet from SCANA. Therefore, Gulf States
    FiberNet's revenues and expenses have been included in the combined
    statement of operations data effective January 1, 1997 with the
    preacquisition losses attributable to SCANA deducted to determine the
    combined net loss for the six months ended June 30, 1997. See note 16 to
    the combined financial statements.     
   
(f) On March 27, 1997, the Company purchased the Georgia Fiber Assets from
    SCANA. The results of operations for the Georgia Fiber Assets are included
    in the combined statements of operations beginning April 1, 1997. See note
    16 to the combined financial statements.     
   
(g) EBITDA represents earnings before extraordinary item, preacquisition
    (earnings) losses, equity in losses of unconsolidated subsidiaries, net
    interest, income taxes, depreciation and amortization. EBITDA is provided
    because it is a measure commonly used in the industry. EBITDA is not a
    measurement 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
    is not necessarily comparable with similarly titled measures for other
    companies.     
   
(h) Earnings consist of income before income taxes, plus fixed charges. Fixed
    charges consist of interest charges and amortization of debt issuance
    costs (including those reflected as an extraordinary item) 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, 1995 and 1996 and the six months
    ended June 30, 1996 and 1997 by $.8 million, $5.1 million, $2.3 million
    and $3.8 million, respectively.

                           PRO FORMA FINANCIAL DATA
   
  As discussed in note 1 to the combined financial statements, the historical
combined financial statements include the financial statements of the
following wholly owned subsidiaries of ITC Holding prior to the
Reorganization: Transmission, Transmission II, Gulf States Transmission,
InterQuest and DeltaCom. The historical combined financial statements include
the results of DeltaCom's operations effective as of the date of acquisition,
January 29, 1996. The Company's historical combined financial statements also
include the results of operations of Interstate FiberNet, a partnership
between Transmission and Transmission II, as well as Gulf States
Transmission's 36% equity interest in the results of operations of Gulf States
FiberNet.     
   
  The pro forma adjustments to the statements of operations for the year ended
December 31, 1996 and for the six months ended June 30, 1997 reflect (i) the
DeltaCom Acquisition, with respect to the year ended December 31, 1996, (ii)
the Gulf States Acquisition, (iii) the Reorganization and (iv) the Offering
and the use of the net proceeds therefrom, as if each of such transactions had
occurred on January 1, 1996. The pro forma adjustments to the balance sheet
reflect (i) the Reorganization, including ITC Holding's forgiveness and
contribution of approximately $31.0 million of DeltaCom Indebtedness to the
Company as additional equity and (ii) the release and use of the net proceeds
from the Offering, as if each of such transactions had occurred on June 30,
1997.     
 
  The pro forma financial and operating information does not purport to
represent what the Company's consolidated results of operations would have
been if these transactions had in fact occurred on these dates, nor does it
purport to indicate the future consolidated financial position or consolidated
results of future operations of the Company. The pro forma adjustments are
based on currently available information and certain assumptions that
management believes to be reasonable.

                 MANAGEMENT'S DISCUSSION AND ANALYSIS OF     
                 
              FINANCIAL CONDITION AND RESULTS OF OPERATIONS     
   
  The following analysis should be read in conjunction with the financial
statements and the notes thereto and the other financial data appearing
elsewhere in this Prospectus. The Company has included EBITDA data in the
following analysis because it is a measure commonly used in the industry.
EBITDA represents earnings before extraordinary item, preacquisition
(earnings) losses, equity in losses of unconsolidated subsidiaries, net
interest, income taxes, depreciation and amortization. EBITDA 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 flows as a measure of liquidity. EBITDA is not
necessarily comparable with similarly titled measures for other companies.
Unless otherwise indicated, dollar amounts have been rounded to the nearest
hundred thousand.     
   
OVERVIEW     
   
  Company Background. ITC/\DeltaCom was incorporated in March 1997 as a wholly
owned subsidiary of ITC Holding to acquire and operate ITC Holding's Retail
Services and Carriers' Carrier Services businesses.     
   
  ITC Holding has provided operator and directory assistance services since
March 1992 through InterQuest. Carriers' Carrier Services have been offered
since late 1992 through Interstate FiberNet, a partnership originally formed
by ITC Holding (with a 49% interest) and SCANA (with a 51% interest). In
August 1994, ITC Holding acquired SCANA's interest in Interstate FiberNet.
Also in August 1994, ITC Holding formed a second partnership with SCANA, Gulf
States FiberNet, to construct and operate a fiber optic route primarily
between Atlanta, Georgia and Shreveport, Louisiana with several supplemental
spur routes. In the Gulf States Acquisition, ITC Holding acquired SCANA's 64%
partnership interest in Gulf States FiberNet and the Georgia Fiber Assets,
which included one customer contract representing $3.5 million in annual
revenues through August 2001, the term of the contract. Members of the
Company's management have been managing the businesses of both Interstate
FiberNet and Gulf States FiberNet since their inception. In 1995, the Company
began offering SS7 Services to its Carriers' Carrier customers.     
   
  In January 1996, as a result of the DeltaCom Acquisition, ITC Holding
entered the retail long distance business and acquired several fiber optic
routes within the State of 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, provides long
distance services to mid-sized businesses primarily in the state of Alabama.
       
  The aggregate consideration paid by ITC Holding in the DeltaCom Acquisition
was approximately $71.4 million, consisting of approximately $65.4 million in
cash and $6.0 million of ITC Holding common stock. Concurrently with its
acquisition of DeltaCom, ITC Holding advanced $8.6 million to DeltaCom to
repay DeltaCom's outstanding debt. The DeltaCom Acquisition has been accounted
for under the purchase method. To finance the DeltaCom Acquisition and to
refinance DeltaCom's existing debt, ITC Holding incurred approximately $74.0
million of indebtedness, which was pushed down to DeltaCom (the DeltaCom
Indebtedness). See "--Effects of Accounting Standards."     
   
  The aggregate consideration paid by ITC Holding in the Gulf States
Acquisition was approximately $27.9 million, consisting of the $10.0 million
SCANA Note, which was assumed by Interstate FiberNet, Inc., and $17.9 million
of ITC Holding preferred stock. Under an earn-out provision, SCANA will be
entitled to receive additional preferred stock of ITC Holding if the Gulf
States FiberNet business achieves a specified performance target for 1997. See
"Description of Indebtedness--SCANA Note." The Company accounted for the Gulf
States Acquisition under the purchase method. Of the purchase price,
approximately $17.0 million was allocated to the Gulf States FiberNet
partnership interest and $10.9 million was allocated to the Georgia Fiber
Assets.     
   
  In connection with the Reorganization, approximately $31.0 million of the
DeltaCom Indebtedness was forgiven by ITC Holding and contributed to the
Company as additional equity. Following the Reorganization,     
 
                                      43
<PAGE>
 
   
the Company repaid the remaining $43.0 million of the DeltaCom Indebtedness,
accrued interest on all $74.0 million of such indebtedness and the $41.6
million of indebtedness outstanding under the Bridge Facility and accrued
interest thereon. See "History of the Company--Reorganization," "Use of
Proceeds" and "--Liquidity and Capital Resources."     
   
  Revenues. The Company derives revenues primarily from two business segments:
(i) Retail Services, which encompass the retail sale of long distance, data,
Internet services and the sale and installation of customer premise equipment
to mid-sized and major regional business customers and certain switched
services telecommunications companies, and (ii) Carriers' Carrier Services,
which encompass the sale of long-haul private line services on a wholesale
basis to other telecommunications companies, using the Company's owned and
managed fiber optic network.     
   
  The Company currently offers a wide range of Retail Services, including
retail long distance services such as traditional switched and dedicated long
distance, 800/888 calling, calling card and operator services, ATM and frame
relay, high capacity broadband private line, as well as Internet, Intranet and
Web page hosting and development services, and customer premise equipment
installation and repair. Since January 1996, the Company has expanded its
retail long distance operations into the following markets: Pensacola,
Florida; Atlanta, Georgia; Charlotte, North Carolina; Greenville, South
Carolina; and New Orleans and Baton Rouge, Louisiana. As ofJune 30, 1997, the
Company provided Retail Services to over 6,600 business customers and
approximately 7,100 residential customers. Such residential customers
represented less than 5% of the Company's revenues for the year ended 1996 and
the six months ended June 30, 1997.     
          
  In July 1997, the Company began offering local exchange services on a
limited, resale basis in Birmingham and Montgomery, Alabama, and commenced a
general sales effort of services on a resale basis in those markets in August
1997. Also in August 1997, the Company initiated a limited offering in
Birmingham and Montgomery of facilities-based local exchange services, and
expects that general marketing of such services will commence in September
1997. Although the Company's local exchange services offerings in such markets
are in the very early stages, initial expressions of customer interest in such
services have been positive, consistent with management's expectations.
However, there can be no assurance that demand for the Company's local
services will match such preliminary indications of customer interest. The
Company expects to offer local exchange services as part of its Retail
Services in a total of six to nine markets (including Birmingham and
Montgomery) by the end of 1997, initially by reselling the services of
incumbent local exchange carriers and, where market conditions warrant, by
using its own local switching facilities.     
   
  In connection with offering local exchange services, the Company has entered
into the Interconnection Agreement with BellSouth to (i) resell BellSouth's
local exchange services and (ii) interconnect the Company's network with
BellSouth's network for the purpose of gaining immediate access to all of
BellSouth's unbundled network elements. This agreement will allow the Company
to enter new markets with minimal capital expenditures and to offer local
exchange service to its current customer base. The Interconnection Agreement
currently allows the Company 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 Company-owned facilities. The terms of the
Interconnection Agreement, including interim pricing terms agreed to by the
Company and BellSouth, have been approved by state regulatory authorities in
most states, although they remain subject to review and modification by such
authorities. In addition, the Interconnection Agreement does not resolve all
operational issues, particularly those relating to the collocation of the
Company's equipment with that of BellSouth. The Company and BellSouth are
continuing to negotiate to resolve such issues. The Company expects that the
Interconnection Agreement will provide a foundation for it to provide local
service on a reasonable commercial basis, but there can be no assurance of
this and important issues remain unsettled as a result of legal and regulatory
developments and related matters. The Interconnection Agreement expires in
1999, and there can be no assurance that the Company will be able to renew it
under favorable terms, or at all.     
   
  The Company's strategy is ultimately to offer facilities-based local service
in certain established markets by collocating its equipment with that of
BellSouth which will enable the Company to purchase fewer unbundled network
elements. The Company expects that it will be able to begin providing local
service to such markets in the fourth quarter of 1997 by using its own
facilities and network, as supplemented by BellSouth's unbundled     
 
                                      44

network elements. In August 1997, the Company began the process of arranging
for collocation of its equipment with BellSouth in certain markets, primarily
in Alabama, in which the Company has an existing base of long distance
customers. The Company and BellSouth are negotiating the terms of an agreement
with respect to such equipment collocations. In addition, BellSouth has been
experiencing certain central office space limitations, resulting in delays in
completing arrangements for physical collocation of Company equipment. There
can be no assurance that the Company and BellSouth will enter into a
collocation agreement on terms acceptable to the Company or at all, nor can
there be any assurance that BellSouth's space limitations will be resolved to
the Company's satisfaction, in a timely manner, or at all. In the event that
collocation is not possible, the Company plans to provide facilities-based
local service primarily by purchasing unbundled network elements.     
   
  The Company anticipates that an increasing portion of its revenue will be
derived from local services, primarily those provided pursuant to the
Interconnection Agreement with BellSouth and similar agreements with other
local exchange carriers. Management expects that gross margin associated with
local Retail Services will be slightly better than gross margin associated
with long distance Retail Services, but that, in general, gross margin
associated with Retail Services will be lower than that associated with
Carriers' Carrier Services. There can be no assurance that the Company will be
able to enter into additional interconnection agreements on terms acceptable
to the Company or at all, or that the incumbent local exchange carriers will
provide the operational support required for the Company to provide local
services to end users. See "Risk Factors--Dependence on Incumbent Local
Exchange Carriers," "--Regulation," "Business--Services and Facilities," and
"--Regulation."     
   
  As the Company begins to offer local service on a facilities rather than
resale basis, it will begin to sell switched access and termination services
to carriers terminating calls to its local end user customers, and originating
switched access to long distance companies where the end users choose a
carrier other than the Company for that service. Certain incumbent local
exchange companies, including BellSouth, have taken the position that when a
carrier seeking to provide local service obtains all necessary elements (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.
Although a recent Eighth Circuit Court of Appeals decision appears to reject
this position, further legal challenges are likely and important issues
related to this form of interconnection remain open.     
   
  The Company provides Carriers' Carrier Services using its owned and managed
fiber optic network, which reaches over 60 POPs in ten southern states
(Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina,
South Carolina, Tennessee and Texas). Of the network's approximately 5,400
route miles, approximately 2,500 are Company-owned and operated and
approximately 2,900 are owned and operated by three public utilities, Duke
Power Company, Florida Power & Light Company and Entergy Technology Company,
with which the Company has marketing and management arrangements. The
Company's arrangement with Entergy is exclusive. In addition, the Company has
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 the
Company to provide customers with access to POPs throughout those states. The
Company expects to add approximately 700 owned and operated route miles to its
fiber network by the end of 1997 and add approximately 100 owned and operated
route miles in early 1998 through long-term dark fiber leases. In addition, as
part of its strategy, the Company intends to continue to evaluate the
potential expansion of its 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 the Company elects to expand its network through
long-term leases in lieu of construction or fiber swap transactions, the
Company expects such leases to have a negative effect on EBITDA; however, the
Company expects that any such expansion of its network would provide
opportunities to generate additional revenues, which would partly offset such
negative effects.     
   
  The Company derives commission revenues from the marketing, sale and
management of capacity on the utility-owned portions of the Company's network.
Negligible incremental costs are associated with these     
 
                                      45
<PAGE>
 
   
commissions, because the Company uses the same marketing and sales force in
servicing the utility-owned portions of the network as it does for the
portions owned by the Company. In 1996, the Company's commission revenues from
these arrangements amounted to approximately $170,000 because, although the
utility-owned portions owned by Duke Power Company began generating revenues
in late 1995, the portions owned by Florida Power & Light Company and Entergy
Technology Company began generating revenues in late 1996. For the six months
ended June 30, 1997, the Company's commission revenues from these arrangements
amounted to approximately $451,000. The Company expects commissions associated
with the utility-owned portions of the network, which will become fully
operational in the current year, to continue to increase in 1997.     
   
  The Company provides long-haul services to its 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 June 30, 1997, the Company had remaining future long-term
contract commitments totaling approximately $75.8 million. These contracts
expire on various dates through 2006 and are expected to generate
approximately $56.0 million in revenues to the Company through 2001, of which
approximately $14.5 million are expected to be realized in 1998. No single
Carriers' Carrier Services customer or Retail Services customer represented
over 10% of the Company's total revenues for the six months ended June 30,
1997.     
   
  Although the Company expects that a majority of its revenue growth will come
from its Retail Services business, the Company does not expect its Retail
Services to obtain a significant share of the market for telecommunications
services in the southern United States. The customer contracts for 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. To date, no customers have terminated any
services under these provisions. 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 the Company believes will likely continue. In response to
these and other competitive pressures, the Company recently modified certain
of its retail contracts to extend to certain customers lower rates over longer
terms as a means of maintaining and developing the Company's customer base. In
the future, in response to competitive considerations, the Company may decide
to modify certain other retail customer contracts in a similar manner,
emphasizing lower pricing and longer commitment periods. A substantial portion
of the Company's total revenues are from retail long distance services.
Revenue per minute from such services has been declining and is expected to
continue to decline. This decline will have a negative effect on the Company's
gross margin which may not be offset completely by savings from decreases in
the Company's cost of services.     
   
  Operating Expenses. The Company's principal operating expenses consist of
cost of services, selling, operations and administration expenses, and
depreciation and amortization. Cost of services related to 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 Carriers' Carrier Services are substantially all fixed
costs attributable to (i) the leasing of dark fiber under long-term operating
leases, (ii) the leasing of capacity outside the Company's owned or managed
network (off-net capacity) to meet customer requirements, (iii) labor
associated with operator services and (iv) network costs associated with the
provision of SS7 Services. The Company purchases off-net capacity to provide
Carriers' Carrier Services in cases where the Company plans to construct its
own network to replace the off-net portion of certain fiber routes. The
Company also purchases off-net capacity in connection with an existing
customer contract, pursuant to which the Company is the exclusive provider of
network capacity to such customer. Although the Company is able to
substantially meet the requirements of such customer on the Company's network,
the Company purchases off-net capacity to fill such customer's requirements
that cannot be met on the Company's network. 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 include
depreciation of the Company's telecommunications network and equipment and
amortization of goodwill and other intangible assets related to acquisitions,
primarily the DeltaCom Acquisition.     
 
                                      46
<PAGE>
 
   
  As the Company continues to expand into new geographic markets, add new
sales offices and facilities and enlarge its current product offerings to
include local telephone and other services, cost of services and selling,
operations and administration expenses are expected to increase substantially.
Therefore, the Company expects to incur increasing operating losses over the
next few years. Although the Company anticipates that it will continue to
generate positive cash flow from operations, it expects that such cash flows
will be more than offset by capital expenditures during the next several years
as it implements its business plan. The Company also expects that the addition
of local service to its bundle of telecommunications services will have an
adverse impact on its gross margin, because the gross margin on the resale of
local services through incumbent local exchange carrier facilities will be
lower than the gross margin on the Company's existing businesses. As the
Company increasingly uses incumbent local exchange carrier unbundled network
elements instead of resold services, the Company expects gross margin on local
service to improve. Such improvement is expected to result from reduced access
charges and efficiencies realized through increased reliance on the Company's
owned network. Such improved margins, however, could be offset by competitive
market pressures to reduce prices for Retail Services, as discussed above.
There can be no assurance that growth in the Company's revenues or customer
base will continue or that the Company will be able to achieve or sustain
profitability or positive net cash flows.     
          
  High Leverage. At June 30, 1997, on a pro forma basis, giving effect to the
Reorganization, as well as the forgiveness of, or repayment in full of certain
indebtedness with a portion of the net proceeds from the Offering, the Company
would have had $214.4 million of indebtedness and its stockholder's equity
would have been $64.1 million. On a pro forma basis, the Company's earnings
would have been insufficient to cover its fixed charges for the year ended
December 31, 1996 and the six months ended June 30, 1997 by $18.2 million and
$6.6 million, respectively, and its EBITDA less capital expenditures and
interest expense would have been negative $14.8 million and negative $13.0
million, respectively.     
          
  Although the Company's liquidity has improved, the Company's level of
indebtedness and debt service obligations has significantly increased as a
result of the Offering. The successful implementation of the Company's
strategy, including expansion of its network and obtaining and retaining a
significant number of customers, and significant and sustained growth in the
Company's cash flow are necessary for the Company to be able to meet its debt
service requirements. There can be no assurance that the Company will
successfully implement its strategy or that the Company will be able to
generate sufficient cash flow from operating activities to improve its
earnings before fixed charges, or to meet its debt service obligations and
working capital requirements. The ability of the Company to meet its
obligations will be dependent upon the future performance of the Company,
which will be subject to prevailing economic conditions and to financial,
business and other factors. See "Risk Factors--Significant Capital
Requirements; Uncertainty of Additional Financing" and --High Leverage;
Ability to Service Debt; Restrictive Covenants," "--Liquidity and Capital
Resources," "Description of Certain Indebtedness" and "Description of the
Exchange Notes."

  Revenues     
   
  Pro forma revenues increased 37% from $39.6 million for the six months ended

Services operations' pro forma revenues increased $8.8 million

from $31.1 million for the six months ended June 30, 1996 to $39.9 million for
the six months ended June 30, 1997. Of this increase, $7.0 million was
attributable to long distance services, $.9 million to sales of customer
premise equipment and $.9 million to Internet sales and services. The growth
in long distance services was primarily the result of an increase in minutes
from new and existing customers, partially offset by a decrease in revenues
per minute due to lower prices. Pro forma revenues from Carriers' Carrier
operations contributed $5.8 million of this increase, increasing from $8.5
million for the six months ended June 30, 1996 to $14.3 million for the six
months ended June 30, 1997. Revenues from Carriers' Carrier Services increased
due to increased demand for Carriers' Carrier Services from new and existing
customers.     
   
  Gross Margin     
   
  Pro forma gross margin increased from $20.3 million for the six months ended
June 30, 1996 to $28.9 million for the six months ended June 30, 1997. Pro
forma gross margin for Carriers' Carrier Services as a percentage of Carrier's
Carrier Services revenues increased from 84% for the six months ended June 30,
1996 to 88% for the six months ended June 30, 1997, primarily due to
additional revenues. Retail Services pro forma gross margin as a percentage of
Retail Services revenues was 42% and 41%, respectively, for the six month
periods ended June 30, 1996 and 1997. The Company anticipates that increased
competition, particularly with respect to pricing, in the long distance market
will likely adversely affect the Company's gross margin on long distance
services as a percentage of revenues. Management expects that the Company will
increasingly utilize its fiber optic network in the deployment of the
Company's switched network design, favorably affecting the Company's gross
margin on the Retail Services segment. As the Company increases the volume of
traffic it either originates or terminates on its own network, it expects to
be able to use more effectively its switched network to reduce per-minute
costs. The Company expects that the provision of local telecommunications
service through the resale of incumbent local exchange carrier facilities will
adversely affect its gross margin. As the Company begins to utilize incumbent
local exchange carrier unbundled network elements instead of reselling local
services, the Company expects gross margin on local services to improve.     
   
  EBITDA     
   
  Pro forma EBITDA increased $2.9 million from $8.8 million for the six months
ended June 30, 1996 to $11.7 million for the six months ended June 30, 1997,
an increase of 33%. For Carriers' Carrier Services, pro forma EBITDA increased
as a percentage of Carrier's Carrier Services revenues from 51% for the six
months ended June 30, 1996 to 59% for the six months ended June 30, 1997,
primarily due to increased revenues. Pro forma EBITDA related to Retail
Services decreased $1.2 million, from $4.4 million for the six months ended
June 30, 1996 to $3.2 million for the six months ended June 30, 1997. This
decrease was attributable to the costs associated with new sales offices
opened since March 31, 1996 and employment of additional support personnel to
better position this segment for growth and expansion. The Company expects
that EBITDA for Retail Services will continue to decline at least through
1998, as the Company expands its offering of local services and opens
additional sales offices.     
   
  Net Income (Loss) From Continuing Operations     
   
  Pro forma net loss decreased $.1 million from $2.3 million for the six
months ended June 30, 1996 to a loss of $2.2 million for the six months ended
June 30, 1997. The pro forma net loss from Retail Services increased from $1.0
million for the six months ended June 30, 1996 to a loss of $2.2 million for
the six months ended June 30, 1997. This additional loss resulted from
increased costs associated with new sales offices opened since March 31, 1996,
and the employment of additional support personnel to better position this
segment for growth and expansion. Carriers' Carrier Services had a net loss of
$1.2 million for the six months ended June 30, 1996 and net income of less
than $.1 million for the six months ended June 30, 1997. This increase in net
income is primarily attributable to increased revenues and gross margins.

PRO FORMA YEAR ENDED DECEMBER 31, 1995 COMPARED TO PRO FORMA YEAR ENDED
DECEMBER 31, 1996     
   
  Revenues     
   
  Pro forma revenues increased 17% from $73.1 million in 1995 to $85.4 million
in 1996. Of this increase, $8.9 million was attributable to Retail Services,
which increased $7.6 million from long distance services and $1.3 million from
Internet services and sales of customer premise equipment. The growth in long
distance services was primarily the result of an increase in minutes from new
and existing customers, which was partially offset by a decrease in revenues
per minute (because of lower prices). The Company also opened six additional
sales offices during the first half of 1996 in the following new markets: New
Orleans, Baton Rouge, Atlanta, Greenville, Charlotte and Pensacola. Carriers'
Carrier Services accounted for $3.4 million of the total revenues increase.
Pro forma revenues for this segment in 1995 included a $3.3 million
nonrecurring payment from a major customer related to the initial construction
of the Gulf States FiberNet fiber optic route. Excluding the effect of this
nonrecurring payment, pro forma revenues attributable to Carriers' Carrier
Services increased 49%, or $6.6 million, to $20.2 million in 1996. Of this
increase, $5.7 million was due to services provided on new network capacity,
primarily the Gulf States FiberNet portions of the network, which were fully
operational for all of 1996, after being operational for only approximately
six months in 1995. The balance of the increase was attributable to increased
demand over existing portions of the Company's network. Gulf States FiberNet
represented $10.1 million and the Georgia Fiber Assets customer contract
represented $3.5 million of the total $20.2 million of Carriers' Carrier
Services pro forma revenues in 1996. For 1995, excluding the effect of the
$3.3 million nonrecurring payment, Gulf States FiberNet represented $4.3
million and the Georgia Fiber Assets customer contract represented $3.5
million of Carriers' Carrier Services pro forma revenues of $13.6 million.
       
  Gross Margin     
   
  Pro forma gross margin increased from $36.4 million in 1995 to $42.8 million
in 1996. For Carriers' Carrier Services, pro forma gross margin as a
percentage of revenues increased from 74% in 1995 to 84% in 1996, primarily
because most Carriers' Carrier Services are long-haul private line services
which have low associated variable cost of services. For Retail Services, pro
forma gross margin as a percentage of revenues decreased from 43% in 1995 to
40% in 1996, primarily because of an increase in the number of wholesale
switched minutes sold to other telecommunications companies as a percentage of
total switched minutes in 1996 compared to 1995. The gross margin on these
wholesale services is lower than the gross margin on retail switched services.
In addition, in 1996, the Company modified certain of its retail contracts to
extend to certain customers lower rates over longer terms as a means of
maintaining and developing the Company's customer base.     
   
  EBITDA     
   
  Pro forma EBITDA increased $.1 million from $18.8 million in 1995 to $18.9
million in 1996. Pro forma EBITDA related to Retail Services decreased $2.7
million from $10.1 million in 1995 to $7.4 million in 1996, principally
because of costs incurred to open six new sales offices during 1996 and the
addition of management and infrastructure after the DeltaCom Acquisition to
position this segment for growth and expansion. EBITDA related to Carriers'
Carrier Services increased from $8.7 million in 1995 to $11.5 million in 1996
on a $3.4 million increase in revenues because the long-haul portion of the
Carriers' Carrier business has low associated variable costs. EBITDA and
revenues for 1995 include a $3.3 million nonrecurring payment related to the
initial construction of the Gulf States FiberNet fiber optic route.     
   
  Net Income (Loss) From Continuing Operations     
   
  Pro forma net loss increased $3.6 million from $1.9 million in 1995 to $5.5
million in 1996. Of this increase, $2.3 million was attributable to Retail
Services primarily due to costs incurred to open six new sales offices during
1996 and addition of management and infrastructure to position this segment
for growth and expansion. Pro forma net loss from Carriers' Carrier Services
increased $1.3 million from $.5 million in 1995 to $1.8 million in 1996. This
increased net loss was primarily attributable to increased depreciation and
amortization expense and increased interest expense.

PRO FORMA YEAR ENDED DECEMBER 31, 1994 COMPARED TO PRO FORMA YEAR ENDED

  Revenues     
   
  Pro forma revenues increased 17% from $62.4 million in 1994 to $73.1 million
in 1995. Revenues from Retail Services accounted for $2.5 million of the $10.7
million total increase, due to an increase of $1.8 million attributable to
long distance services and $.7 million attributable to sales of customer
premise equipment. Revenues from Carriers' Carrier Services contributed $8.3
million to the total increase, including a $3.3 million nonrecurring payment
from a major customer related to the initial construction of the Gulf States
FiberNet fiber optic route. Excluding the effect of this nonrecurring payment,
$4.2 million of the $5.0 million increase in revenues attributable to
Carriers' Carrier Services consisted of revenues generated from the newly
constructed Gulf States FiberNet route, which began operations in June 1995.
The remaining $.8 million was attributable to increased sales on existing
network routes and the sale of newly introduced SS7 Services.     
   
  Gross Margin     
   
  Pro forma gross margin as a percentage of revenues increased from 42% in
1994 to 50% in 1995. Pro forma gross margin as a percentage of revenues
generated by Retail Services increased from 38% in 1994 to 43% in 1995. This
improvement was primarily a result of (i) reductions in the cost of intrastate
switched access and (ii) newly renegotiated favorable contract terms resulting
in higher revenues to the Company for off-net originating and terminating
interstate services. As a result of the increased revenues derived from
Carriers' Carrier Services, pro forma gross margin as percentage of revenues
generated by this business segment increased from 67% in 1994 to 75% in 1995.
       
  EBITDA     
   
  Pro forma EBITDA increased 34% from $14.0 million in 1994 to $18.8 million
in 1995. Pro forma EBITDA related to Retail Services increased slightly from
$10.0 million in 1994 to $10.1 million in 1995. Increases in pro forma 1995
gross margin for Retail Services were partially offset by approximately $1.0
million of costs related to personnel additions to the Company's human
resources, marketing, customer service and information services departments
and approximately $.6 million of costs related to management services.
Although pro forma revenues related to Carriers' Carrier Services increased
$8.3 million in 1995 compared to 1994, pro forma EBITDA for Carriers' Carrier
Services only increased $4.7 million from $4.0 million in 1994 to $8.7 million
in 1995. The Carriers' Carrier Services revenues increase was offset in part
by (i) a $1.5 million increase in cost of services related primarily to
network costs associated with the initiation of SS7 Services, a network
management contract for a large enhanced specialized mobile radio customer and
off-net lease expense incurred in the sale of certain long-haul private lines
and (ii) a $2.0 million increase in selling, operations and administration
expense related to the hiring of additional senior management and key
operations personnel to position the Company for future growth. Also included
in this $2.0 million increase is the opening of a fully staffed network
operation center to monitor the entire fiber optic network 24 hours a day,
seven days a week.     
   
  Net Income (Loss) From Continuing Operations     
   
  Pro forma net loss increased $1.3 million from $.6 million in 1994 to $1.9
million in 1995. This increased loss was attributable to the loss from
Carriers' Carrier Services which increased $1.3 million to a net loss of $.5
million in 1995 as compared to net income of $.8 million in 1994. This loss
was attributable to (i) an increase in selling, operations and administration
expense related to the hiring of additional management and key operations
personnel to position the Company for future growth and (ii) an increase in
depreciation and amortization expense and interest expense which resulted
primarily from the operations of the Gulf States FiberNet routes which
commenced in August 1994.

HISTORICAL RESULTS OF OPERATIONS     
   
  The following tables set forth certain historical financial data for the
years ended December 31, 1994, 1995 and 1996 and the six months ended June 30,
1996 and 1997 for the Carriers' Carrier Services business and for the year
ended December 31, 1996 and the six months ended June 30, 1996 and 1997 for
the Retail Services business.     
   
  The comparability of the historical financial data for the six months ended
June 30, 1996 and 1997 has been affected by the DeltaCom Acquisition and the
Gulf States Acquisition. The historical financial statements for the six
months ended June 30, 1996 include the results of operations for DeltaCom
since its acquisition on January 29, 1996. For the six months ended June 30,
1996, the Company's 36% interest in Gulf States FiberNet's results of
operations is reflected using the equity method. Due to the Gulf States
Acquisition on March 27, 1997, the results of operations for the six months
ended June 30, 1997 reflect the total revenues and expenses from January 1,
1997 attributable to Gulf States FiberNet with the preacquisition losses
attributable to SCANA from January 1, 1997 deducted to determine combined net
loss. The results of operations for the six months ended June 30, 1997 also
reflect the revenues and expenses of Georgia Fiber since April 1, 1997.

  Revenue for the six months ended June 30, 1997 increased from $28.6 million
for the six months ended June 30, 1996 to $53.4 million for the six months
ended June 30, 1997. Revenues from Retail Services increased $14.1 million

ended June 30, 1997. Results for the six months ended June 30, 1996 reflect
only five months of Retail Services revenues because the DeltaCom Acquisition
occurred on January 29, 1996. Revenues from Carriers' Carrier Services
increased from $2.7 million for the six months ended June 30, 1996 to $13.4
million for the six months ended June 30, 1997. Of the $10.7 million increase,
$8.8 million was attributable to revenues generated during the six months
ended June 30, 1997 by Gulf States FiberNet. Excluding revenues attributable
to Gulf States FiberNet during the six months ended June 30, 1997, Carriers'
Carrier Services increased $1.9 million, of which $.9 million was attributable
to revenue from the Georgia Fiber Assets acquired March 27, 1997.     
   
  Cost of Services     
   
  Cost of services increased $9.2 million from $16.1 million for the six
months ended June 30, 1996 to $25.3 million for the six months ended June 30,
1997. Cost of services for Retail Services' operations increased $8.5 million
to $23.5 million for the six months ended June 30, 1997 from $15.0 million for
the six months ended June 30, 1996, which reflect only five months of cost of
services attributable to Retail Services operations. Cost of services for
Retail Services' operations as a percentage of revenue increased to 59% for
the six months ended June 30, 1997 compared to 58% for the six months ended
June 30, 1996. This increase was attributable to the cost of new facilities in
order to service expanded retail markets, and the impact of increased minutes
of usage at lower prices per minute. Cost of services attributable to
Carriers' Carrier Services increased $.7 million from $1.1 million for the six
months ended June 30, 1996 to $1.8 million for the six months ended June 30,
1997. Cost of services for Carriers' Carrier Services as a percentage of
revenue decreased to 13% for the six months ended June 30, 1997 compared to
41% for the six months ended June 30, 1996.     
   
  Selling, Operations and Administration Expense     
   
  Selling, operations and administration expense increased $8.8 million from
$8.2 million (29% as a percentage of revenue) for the six months ended June
30, 1996 to $17.0 million (32% as a percentage of revenue) for the six months
ended June 30, 1997. Selling, operations and administration expense
attributable to Retail Services increased $5.8 million from $7.4 million (or
28% of Retail Services revenues) for the six months ended June 30, 1996 to
$13.2 million (or 33% of Retail Services revenues) for the six months ended
June 30, 1997. This increase resulted from employment of additional sales,
information services and provisioning personnel to support the Company's
geographical market and product expansion as the Company prepared to offer
local service and expand into new markets. Results for the six months ended
June 30, 1996 reflect only five months of selling, operations and
administration expense attributable to Retail Services. Selling, operations
and administration expense attributable to Carriers' Carrier Services
increased $2.9 million from $.9 million (or 31% of Carriers' Carrier Services
revenues) for the six months ended June 30, 1996 to $3.8 million (or 28% of
Carriers' Carrier Services revenues) for the six months ended June 30, 1997.
Of the $2.9 million increase, $1.8 million was attributable to the acquisition
of Gulf States FiberNet. The remaining $1.1 million of this increase was
attributable to increased costs of administrative personnel employed to
support expansion of the business.     
   
  Depreciation and Amortization     
   
  Depreciation and amortization expense increased $5.5 million from $2.8
million for the six months ended June 30, 1996 to $8.3 million for the six
months ended June 30, 1997. Retail Services accounted for $.9 million of the
increase, which was primarily related to installation of new central office
equipment. Depreciation and amortization for Carriers' Carrier Services
operations accounted for $4.6 million of the increase and was primarily
related to the acquisition of Gulf States FiberNet.     
   
  Interest Expense     
   
  Interest expense increased from $2.8 million for the six months ended June
30, 1996 to $7.6 million for the six months ended June 30, 1997. Of this $4.8
million increase, $2.2 million was attributable to the acquisition of Gulf
States FiberNet, $1.8 million was attributable to the Senior Notes, $.5
million was attributable to the DeltaCom Indebtedness, and the balance was
attributable to the acquisition of Georgia Fiber Acquisition.

  Income Taxes     
   
  The Company is included in the consolidated federal income tax returns of
its parent, ITC Holding, which results in the Company receiving benefits for
certain of its net operating losses. The benefit received as a percentage of
taxable income was 26% and 29% for the six month periods ended June 30, 1997
and 1996, respectively.     
   
  EBITDA     
   
  EBITDA increased from $4.2 million for the six months ended June 30, 1996 to
$11.1 million for the six months ended June 30, 1997. Carriers' Carrier
Services accounted for $7.1 million of the increase. EBITDA attributable to
Retail Services for the six months ended June 30, 1996 was $3.5 million,
compared to $3.2 million for the six months ended June 30, 1997. EBITDA
attributable to Retail Services decreased from 14% of revenues for the six
months ended June 30, 1996 to 8% for the six months ended June 30, 1997,
primarily due to increased costs associated with the expansion of new sales
offices and the employment of additional support personnel to position this
segment for growth and expansion. The Company expects that EBITDA for Retail
Services will continue to decline through at least 1998 as the Company opens
additional sales offices and prepares to offer local service.     
   
HISTORICAL YEAR ENDED DECEMBER 31, 1995 COMPARED WITH HISTORICAL YEAR ENDED
DECEMBER 31, 1996     
   
  Revenues     
   
  Revenues increased from $5.8 million in 1995 to $66.5 million in 1996. The
$60.7 million increase was primarily attributable to revenues of $59.9 million
generated by DeltaCom since it was acquired on January 29, 1996. Revenues from
Carriers' Carrier Services increased approximately $800,000 in 1996 (15%),
primarily due to the growth in new SS7 Services and directory assistance
products and growth in demand for Carriers' Carrier Services.     
   
  Cost of Services     
   
  Cost of services increased from $3.1 million in 1995 to $38.8 million in
1996. DeltaCom's operations accounted for $36.4 million of this increase.
Carriers' Carrier Services accounted for a decrease of $700,000 primarily due
to intersegment eliminations related to its utilization of DeltaCom's network
infrastructure.     
   
  Selling, Operations and Administration Expense     
   
  Selling, operations and administration expense increased from $1.6 million
in 1995 to $18.9 million in 1996. DeltaCom's operations accounted for $17.1
million of the increase. Carriers' Carrier Services accounted for $200,000 of
the increase.     
   
  Depreciation and Amortization     
   
  Depreciation and amortization expense increased from $1.3 million in 1995 to
$6.4 million in 1996. Of this $5.1 million increase, $4.8 million was
attributable to DeltaCom, including $1.3 million of intangible amortization on
$54.6 million of intangibles pushed down to the Company. See "--Effects of
Accounting Standards." Carriers' Carrier Services accounted for $300,000 of
the increase as a result of additional capital expenditures made for the
provision of SS7 Services, capital expenditures associated with the Company's
network management systems required to support the various management and
marketing agreements with various utilities, and small electronic overbuilds
on existing network segments.     
   
  Other Income (Expense)     
   
  Other expense increased from $200,000 in 1995 to $1.4 million in 1996. The
Company's share of Gulf States FiberNet's partnership losses accounted for
$1.3 million of this increase, which was partially offset by a     
 
                                      54
<PAGE>
 
   
$100,000 increase in other interest and miscellaneous income. Gulf States
FiberNet began full operations in late 1995 and, accordingly, the effect of a
full year of operations was not reflected until 1996. Gulf States FiberNet
recorded a pretax loss of $4.4 million in 1996, compared to a pretax loss of
$700,000 in 1995. As of December 31, 1995 and 1996, the Company owned 36% of
Gulf States FiberNet and recorded losses of $300,000 and $1.6 million,
respectively, from such interest.     
   
  Interest Expense     
   
  Interest expense increased from $300,000 in 1995 to $6.2 million in 1996.
The increase was primarily attributable to the increase in the Company's
aggregate indebtedness resulting from the $74.0 million of DeltaCom
Indebtedness. See "--Effects of Accounting Standards." The Company incurred
interest expense of $5.8 million related to such indebtedness in 1996.     
   
  EBITDA     
   
  EBITDA increased from $800,000 in 1995 to $7.5 million in 1996. DeltaCom
accounted for $6.6 million and Carriers' Carrier Services accounted for
$100,000 of the increase. The increased EBITDA attributable to Carriers'
Carrier Services is a result of an increase in revenues with minimal increases
in associated variable costs.     
   
HISTORICAL YEAR ENDED DECEMBER 31, 1994 COMPARED WITH HISTORICAL YEAR ENDED
DECEMBER 31, 1995     
   
  Revenues     
   
  Revenues increased from $4.9 million in 1994 to $5.8 million in 1995. The
increase was primarily attributable to additional capacity sales on the
Atlanta-to-Columbus fiber route and the introduction of SS7 Services in early
1995. Revenues from operator services remained stable between years at
approximately $2.5 million.     
   
  Cost of Services     
   
  Cost of services increased from $2.5 million in 1994 to $3.1 million in
1995, primarily as a result of network costs associated with SS7 Services in
1995 and the network management contract for a large enhanced specialized
mobile radio customer.     
   
  Selling, Operations and Administration Expense     
   
  Selling, operations and administration expense increased from $900,000 in
1994 to $1.6 million in 1995. The increase principally reflected higher
management and personnel costs resulting from the hiring of additional senior
management and a team of key operations personnel in order to position the
Company for future growth.     
   
  Depreciation and Amortization     
   
  Depreciation and amortization expense increased from $700,000 in 1994 to
$1.3 million in 1995. The $600,000 increase in depreciation and amortization
resulted from additional depreciation on capital assets related to the
establishment of the network operations center that operates 24 hours a day,
seven days a week, several minor spur routes, the initiation of SS7 Services,
and ongoing capital expenditures for Carriers' Carrier Services.     
   
  Other Income (Expense)     
   
  Other expense increased from less than $100,000 in 1994 to $200,000 in 1995.
The Company's share of the partnership losses related to Gulf States FiberNet
accounted for this increase. Gulf States FiberNet was in the construction
phase during 1994 and incurred a pretax loss of $300,000 in 1994, compared to
a pretax loss of $700,000 in 1995. As of December 31, 1994 and 1995, the
Company owned 36% of Gulf States FiberNet and recorded equity in partnership
losses of $100,000 and $300,000, respectively. The equity in partnership
losses was partially offset by other miscellaneous income in both years.     
 
                                      55
<PAGE>
 
   
  EBITDA     
   
  EBITDA decreased from $1.3 million in 1994 to $800,000 in 1995. The decrease
in EBITDA primarily reflected increased selling, operations and administration
expense incurred in connection with the hiring of additional senior
management, as discussed above, and additional expense related to the
Company's initiation of SS7 Services.     
   
LIQUIDITY AND CAPITAL RESOURCES     
   
  The Company has historically generated positive cash flow from operations
from its existing lines of business, but has required equity infusions and
advances from ITC Holding to finance a significant portion of its investing
and financing activities. Cash flow from operations totaled $979,000, $1.4
million and $8.2 million for 1994, 1995 and 1996, respectively, and $9.4
million for the six months ended June 30, 1997. Cash flow from operations
(consisting of net loss adjusted for depreciation, amortization, deferred
income taxes, equity in losses of investee, preacquisition losses,
extraordinary item--loss on extinguishment of debt and other) totaled $1.4
million, $1.5 million and $4.7 million for 1994, 1995 and 1996, respectively,
and $5.7 million for the six months ended June 30, 1997. Changes in working
capital used $443,000 and $42,000 in 1994 and 1995, respectively, and provided
$3.5 million and $3.7 million for 1996 and the six months ended June 30, 1997,
respectively. Such changes were primarily due to an increase in accounts
receivable in 1994 and 1995, and an increase in accrued interest, partially
offset by an increase in accounts receivable during 1996. Such changes were
primarily due to increases in unearned revenue, accrued liabilities and income
tax refunds receivable, offset by increases in accounts receivable for the six
months ended June 30, 1997.     
          
  Cash used for investing activities was $10.7 million, $1.5 million and $72.7
million for the years ended December 31, 1994, 1995 and 1996, respectively,
and $11.8 million for the six months ended June 30, 1997. The cash used in
1996 was primarily attributable to the investment of $63.5 million, net of
cash received, in connection with the DeltaCom Acquisition in January 1996.
The Company made capital expenditures of $3.7 million, $1.8 million and $6.2
million for the years ended December 31, 1994, 1995 and 1996, respectively,
and $12.4 million for the six months ended June 30, 1997. Of the $6.2 million
of capital expenditures in 1996, $4.1 million related to Retail Services and
$2.1 million related to Carriers' Carrier Services. In addition, the Company
contributed an additional $2.4 million to Gulf States FiberNet in 1996 to meet
debt service requirements and to fund additional capital requirements of that
business. Of the $12.4 million of capital expenditures for the six months
ended June 30, 1997, $5.7 million related to Carriers' Carrier Services and
$6.7 million related to Retail Services.     
   
  Cash provided by financing activities was $10.1 million, $200,000, and $65.1
million for the years ended December 31, 1994, 1995 and 1996, respectively,
and $201.3 million for the six months ended June 30, 1997. Net cash provided
by financing activities for the six months ended June 30, 1997 consisted
primarily of net proceeds of $194.3 million from the sale of the Senior Notes
and $8.2 million of advances received from ITC Holding. For 1996, most of the
cash provided by financing activities was attributable to the DeltaCom
Indebtedness, which was advanced to the Company by ITC Holding from funds
borrowed under a bank facility. See "--Effects of Accounting Standards."     
   
  ITC Holding partially financed the DeltaCom Acquisition and the Gulf States
Acquisition with debt, which consists of the following: (i) a $74.0 million
term loan under a bank facility incurred in connection with the DeltaCom
Acquisition and pushed down to the Company (the DeltaCom Indebtedness); (ii) 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 (iii) the $10.0 million SCANA Note issued in connection
with the Gulf States Acquisition and assumed by the Company.     
   
  Upon consummation of the Reorganization on July 25, 1997, approximately
$62.7 million of the $192.7 million of net proceeds from the sale of the
Senior Notes in the Offering were used to purchase U.S. government securities
that are being held by the Trustee in a pledged account as security for and to
fund the first     
 
                                      56
<PAGE>
 
   
six scheduled interest payments on the Senior Notes and Exchange Notes. The
balance of the net proceeds from the Offering, approximately $131.6 million,
was released to the Company. A portion of the released proceeds was applied on
July 25, 1997 as follows: (i) to repay approximately $48.3 million of
indebtedness to ITC Holding (together with approximately $9.5 million of
accrued interest) associated with the DeltaCom Acquisition and advances used
by the Company for capital expenditures; and (ii) to repay approximately $41.6
million of indebtedness incurred under the Bridge Facility (together with
approximately $.2 million of accrued interest). The Company intends to use the
remaining approximately $32.2 million of such net proceeds (i) to fund market
expansion activities of the Company's telecommunications business, including
development and construction costs of the Company's fiber optic network and
its regional sales offices; and (ii) for additional working capital and other
general corporate purposes, including the funding of cash flow deficits (after
capital expenditures). Pending such uses, the Company has invested such
amounts in U.S. government securities. In connection with the Reorganization,
$31.0 million of the DeltaCom Indebtedness was forgiven by ITC Holding and
contributed to the Company as additional equity.     
   
  In January 1995, Gulf States FiberNet entered into an interest rate swap
agreement with a $47.5 million principal amount. The agreement swapped the
applicable three-month LIBOR rate selected under Gulf States FiberNet's
project facility with a fixed rate of 8.25%. As of June 30, 1997, Gulf States
FiberNet would have been required to pay $2,142,916 to terminate the interest
rate swap. Gulf States FiberNet made payments totaling $553,320, $1,261,000
and $540,997 for the years ended December 1995 and 1996 and the six months
ended June 30, 1997, respectively, in connection with this interest rate swap
agreement. Although the related debt (the Bridge Facility) has been repaid,
the Company does not currently intend to terminate this interest rate swap
agreement since the Company plans to draw upon its variable rate Credit
Facility to fund capital expenditures and operating losses in accordance with
its expansion plans. The interest rate swap agreement expires in December
2002.     
   
  To achieve its business plan, the Company will need significant financing
for capital expenditure and working capital requirements, including repayment
of indebtedness and operating losses. Expansion of the Company's network,
operations and services will require significant capital expenditures. The
Company currently estimates that its aggregate capital requirements will total
approximately $104 million in 1997 and 1998, of which a total of approximately
$50 million is expected to be incurred in 1997 (including $12.4 million of
capital expenditures made as of June 30, 1997) and approximately $54 million
is expected to be incurred in 1998. The Company expects to make substantial
capital expenditures thereafter. Capital expenditures will be primarily for:
(i) addition of facilities-based local telephone service to its bundle of
integrated telecommunications services, including acquisition and installation
of switches and related equipment, (ii) market expansion, (iii) continued
development and construction of its fiber optic network (including
transmission equipment) and (iv) infrastructure enhancements, principally for
information systems. At June 30, 1997, the Company had entered into agreements
with vendors to purchase approximately $11.5 million of equipment and
services, and, for the six months ended June 30, 1997, had made capital
expenditures of $12.4 million. The actual amount and timing of the Company's
capital requirements may differ materially from the foregoing estimate as a
result of regulatory, technological and competitive developments (including
market developments and new opportunities) in the Company's industry. See
"Risk Factors--Significant Capital Requirements; Uncertainty of Additional
Financing."     
   
  In May 1997, Interstate FiberNet, Inc., a wholly owned subsidiary of the
Company, entered into a commitment letter with NationsBank, N.A. for a five-
year term and revolving credit facility of up to $100 million, to be used for
working capital and other corporate purposes, including capital expenditures
and permitted acquisitions. The Company expects to enter into the Credit
Facility in September 1997, but there can be no assurance that the Credit
Facility will be entered into on this schedule or at all. The Credit Facility
is expected to consist of a $50 million multi-draw term facility and a $50
millions revolving credit facility, and will contain restrictions on the
Company and its subsidiaries and require the Company to comply with certain
financial tests and to maintain certain financial ratios. The Commitment
Letter contemplates that the Credit Facility will be guaranteed by the
Company, DeltaCom and Gulf States Transmission Systems, Inc. and will be
secured by a first priority lien on all current and future assets of the
Company's subsidiaries and a first priority

pledge of the stock of the Company's subsidiaries. See "Risk Factors--High
Leverage; Ability to Service Debt; Restructure Covenants" and "Description of
Certain Indebtedness--Credit Facility."     
   
  The Company will be dependent on additional capital to fund its growth, as
well as to fund continued operating losses and working capital. The Company
believes that the net proceeds from the Senior Notes, together with cash flow
from operations and borrowings expected under the Credit Facility, will
provide sufficient funds to enable the Company to expand its business as
currently planned through the maturity of the Credit Facility in 2002, after
which the Company will need to seek additional financing to fund capital
expenditures and working capital. Because the Credit Facility is expected to
mature in 2002, the Company may not have a ready source of liquidity after
2002. In the event that the Company's plans or assumptions change or prove to
be inaccurate, the foregoing sources of funds may prove to be insufficient to
fund the Company's currently planned growth and operations. In addition, if
the Company successfully completes any acquisitions, the Company may be
required to seek additional capital sooner than currently anticipated.
Additional sources may include equity and debt financings and other financing
arrangements, such as vendor financing. There can be no assurance that the
Company 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 the Company. Failure to generate
or obtain sufficient funds would result in delay or abandonment of some or all
of the Company's development and expansion plans, which could have a material
adverse effect on the Company's ability to service its debt, including the
Senior Notes and the Exchange Notes.     
   
  At June 30, 1997, on a pro forma basis, giving effect to the Reorganization,
including the forgiveness of, or repayment in full of certain indebtedness
with a portion of the net proceeds from the Offering, the Company would have
had $214.4 million of indebtedness and its stockholder's equity would have
been $64.1 million. On a pro forma basis, the Company's earnings would have
been insufficient to cover its fixed charges for the year ended December 31,
1996, and the six months ended June 30, 1997 by $18.2 million and $6.6
million, respectively, and its EBITDA less capital expenditures and interest
expense would have been negative $14.8 million and negative $13.0 million,
respectively.     
   
  Although the Company's liquidity has improved, the Company's level of
indebtedness and debt service obligations has significantly increased as a
result of the Offering. The successful implementation of the Company's
strategy, including expansion of its network and obtaining and retaining a
significant number of customers, and significant and sustained growth in the
Company's cash flow are necessary for the Company to be able to meet its debt
service requirements. There can be no assurance that the Company will
successfully implement its strategy or that the Company will be able to
generate sufficient cash flow from operating activities to improve its
earnings before fixed charges, or to meet its debt service obligations and
working capital requirements. The ability of the Company to meet its
obligations will be dependent upon the future performance of the Company,
which will be subject to prevailing economic conditions and to financial,
business and other factors. See "Risk Factors--Significant Capital
Requirements; Uncertainty of Additional Financing" and --High Leverage;
Ability to Service Debt; Restrictive Covenants," "Description of Certain
Indebtedness" and "Description of the Exchange Notes."     
   
EFFECTS OF ACCOUNTING STANDARDS     
   
  SFAS No. 121 and SFAS No. 123. Statement of Financial Accounting Standards
("SFAS") No. 121, Accounting for the Impairment of Long-lived Assets and for
Long-lived Assets to Be Disposed Of, issued by the Financial Accounting
Standards Board, requires the Company to review for impairment, and
potentially write down, the carrying values of long-lived assets and certain
identifiable intangibles (including goodwill) to be held and used by the
Company whenever events or changes in circumstances indicate that the carrying
amount of any such asset may not be recoverable. The Company adopted SFAS No.
121, effective January 1, 1996, with no material impact on the combined
financial statements.     
   
  SFAS No. 123, Accounting for Stock-Based Compensation, establishes a fair
value based method for financial accounting and reporting stock-based employee
compensation plans. Companies may elect to adopt the     
 
                                      58
<PAGE>
 
   
measurement criteria of SFAS No. 123 for accounting purposes, thereby
recognizing compensation expense in results of operations on a prospective
basis, or to disclose the pro forma effects of the new measurement criteria.
The Company has elected to disclose the pro forma effects of the new
measurement criteria. See note 9 to the combined financial statements.     
   
  "Push Down" of Assets and Liabilities Related to the Acquisitions. ITC
Holding financed the cash purchase price for the DeltaCom Acquisition of
approximately $65.4 million and related debt refinancing of approximately $8.6
million principally with debt. The DeltaCom Acquisition was accounted for
under the purchase method of accounting. In accordance with applicable
accounting requirements of the Securities and Exchange Commission, purchase
transactions that result in one entity becoming substantially wholly owned by
the acquiror establish a new basis of accounting for the purchased assets and
liabilities. Thus, the purchase price for the DeltaCom Acquisition has been
allocated to the underlying assets purchased and liabilities assumed based on
their estimated fair values at January 29, 1996, the acquisition date. Because
the DeltaCom Acquisition was recorded as a purchase, generally accepted
accounting principles require that the purchase price paid and the debt
incurred by ITC Holding for the DeltaCom Acquisition (and the related assets)
be "pushed down" to establish a new accounting basis in DeltaCom's financial
statements so that the basis of accounting for the purchased assets and
liabilities is the same between ITC Holding and DeltaCom. This accounting
treatment is also required because the Company used a portion of the proceeds
of the Offering to repay a significant portion of the debt incurred by ITC
Holding to finance the DeltaCom Acquisition. Similarly, the purchase price and
debt associated with the Gulf States Acquisition was also "pushed down" to the
financial statements of Interstate FiberNet and Gulf States Transmission.     
   
INFLATION     
   
  The Company does not believe that inflation has had a significant impact on
the Company's combined operations.

                                   BUSINESS
   
  The Company provides retail long distance services to mid-sized and major
regional businesses in the southern United States and is a leading regional
provider of Carriers' Carrier Services. The Company intends to become a
leading regional provider of integrated telecommunications services to mid-
sized and major regional businesses in the southern United States by offering
such customers a broad range of telecommunications services, including local
exchange and long distance data and voice, Internet and operator services, and
the sale and servicing of customer premise equipment, in a single package
tailored to the business customer's specific needs. In 1996, the Company had
pro forma revenues of approximately $85.4 million, EBITDA of approximately
$18.9 million and net loss from continuing operations of approximately $12.1
million. For the six months ended June 30, 1997, the Company had pro forma
revenues of approximately $54.3 million, EBITDA of approximately $11.7 million
and net loss from continuing operations of approximately $4.5 million.     
   
  The Company provides Carriers' Carrier Services to other telecommunications
carriers, including AT&T, MCI, Sprint, WorldCom, Cable & Wireless, LCI,
Frontier and IXC. The Company's fiber optic network reaches over 60 POPs in
ten southern states (Alabama, Arkansas, Florida, Georgia, Louisiana,
Mississippi, North Carolina, South Carolina, Tennessee and Texas) and extends
approximately 5,400 route miles, of which approximately 2,500 miles are
Company-owned and approximately 2,900 miles are owned and operated by three
public utilities (Duke Power Company, Florida Power & Light Company and
Entergy Technology Company) and managed and marketed by the Company. The
Company expects to add approximately 700 route miles to its fiber network by
the end of 1997 and add approximately 100 owned and operated route miles in
early 1998 through long-term dark fiber leases. In 1996, the Company's
Carriers' Carrier Services business generated pro forma revenues of
approximately $20.2 million, EBITDA of approximately $11.5 million and net
loss from continuing operations of approximately $1.8 million. For the six
months ended June 30, 1997, the Company's Carriers' Carrier Services business
generated pro forma revenues of approximately $14.3 million, EBITDA of
approximately $8.5 million and net income from continuing operations of less
than $0.1 million. As of June 30, 1997, on a pro forma basis, the Company had
remaining future long-term contract commitments totaling approximately $75.8
million. These contracts expire on various dates through 2006 and are expected
to generate approximately $56.0 million in revenues to the Company through
2001, of which approximately $14.5 million are expected to be realized in
1998.     
   
  The Company currently provides a variety of Retail Services, including
retail long distance services such as traditional switched and dedicated long
distance, 800/888 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 development services, and customer premise
equipment installation and repair. As of June 30, 1997, the Company provided
services to over 6,600 business customers. The Company currently offers Retail
Services, other than local exchange services (which are provided in two
markets), in 12 metropolitan areas in Alabama, Florida, Georgia, Louisiana,
North Carolina and South Carolina and intends to provide a full range of
Retail Services (including local exchange services) in approximately 15
additional metropolitan areas throughout the southern United States over the
next five years. In 1996, the Retail Services business generated pro forma
revenues of approximately $65.2 million, EBITDA of approximately $7.4 million
and net loss from continuing operations of approximately $3.7 million. For the
six months ended June 30, 1997, the Retail Services business generated pro
forma revenues of approximately $39.9 million, EBITDA of approximately $3.2
million and net loss from continuing operations of approximately $2.2 million.
    
       
          
  In connection with offering local exchange services, the Company has entered
into the Interconnection Agreement with BellSouth to (i) resell BellSouth's
local exchange services and (ii) interconnect the Company's network with
BellSouth's network for the purpose of gaining immediate access to all of
BellSouth's unbundled network elements. This agreement will allow the Company
to enter new markets with minimal capital expenditures and to offer local
exchange service to its current customer base. The Interconnection Agreement
currently allows the Company 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 Company-owned facilities. The terms of the
Interconnection Agreement, including interim pricing terms agreed to by the
Company and     
 
                                      60
<PAGE>
 
   
BellSouth, have been approved by state regulatory authorities in most states,
although they remain subject to review and modification by such authorities.
In addition, the Interconnection Agreement does not resolve all operational
issues, particularly those relating to the collocation of the Company's
equipment with that of BellSouth. The Company and BellSouth are continuing to
negotiate to resolve such issues. The Company expects that the Interconnection
Agreement will provide a foundation for it to provide local service on a
reasonable commercial basis, but there can be no assurance of this and
important issues remain unsettled as a result of legal and regulatory
developments and related matters. The Interconnection Agreement expires in
1999, and there can be no assurance that the Company will be able to renew it
under favorable terms, or at all.     
 
  ITC^DeltaCom was incorporated in Delaware. The Company's principal executive
offices are located at 206 West Ninth Street, West Point, Georgia 31833, and

INDUSTRY OVERVIEW
 
  The long distance and local telecommunications markets are currently
undergoing substantial changes, including fundamental changes resulting from
the February 8, 1996 enactment of the Telecommunications Act, and the Company
believes that it is well positioned to take advantage of these developments.
 
  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.
   
  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: (i) local network
services, which generally include basic dial tone, enhanced calling features
and data services (dedicated point-to-point and frame relay service); (ii)
network access services, which consist of access provided by local exchange
carriers to long distance network carriers; (iii) short-haul long distance
network services, which include intraLATA long distance calls; and (iv) other
varied services, including the publication of "white page" and "yellow page"
telephone directories. Industry sources have estimated that the 1995 aggregate
revenues of all local exchange carriers approximated $95 billion. Until
recently, there was virtually no competition in the local exchange markets.
    
  Since 1984, several factors have served to promote competition in the local
exchange market, including: (i) rapidly growing customer demand for an
alternative to the local exchange carrier monopoly, spurred partly by the
development of competitive activities in the long distance market; (ii)
advances in the technology for transmission of data and video, which require
significant capacity and reliability levels; (iii) the development of fiber
optics and digital electronic technology, which reduced network construction
costs while increasing transmission speeds, capacity and reliability as
compared to copper-based networks; (iv) the significant access charges
interexchange carriers are required to pay to local exchange carriers to
access the local exchange carriers' networks; and (v) 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.
In particular, 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 will be
required to complete local calls originated by the Company's customers and
switched by the Company and to deliver inbound local calls to the Company for
termination to its customers, assuring customers of unimpaired local calling
ability. The Company expects to obtain access to incumbent carrier local
"loop" facilities (the transmission lines connecting customers' premises to
the public telephone network) on an unbundled basis at reasonable rates. In
addition, local exchange carriers
 
                                      61
<PAGE>
 
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. The
Company believes that, as a result of continued regulatory and technological
changes and competitive trends, competitive local telecommunications companies
have substantial opportunities for growth.
 
BUSINESS STRATEGY
   
  The Company's objectives are to maintain its leadership position in the
provision of Carriers' Carrier Services and to become a leading provider of
Retail Services in the southern United States. The Company intends to increase
its market share in existing markets and expand into new markets by: (i)
aggressively expanding its customer base and increasing its telecommunications
services, including reselling services and facilities of the incumbent local
exchange carriers; (ii) leveraging the Company's extensive network in its
Retail Services and Carriers' Carrier Services businesses; (iii) concurrently
constructing or obtaining access to additional network infrastructure to serve
its customers more cost-effectively; and (iv) expanding its regional network
of sales offices. The principal elements of the Company's business strategy
include the following:     
 
  Providing Integrated Telecommunications Services to Existing Base of Mid-
sized and Major Regional Business Customers. By providing additional
telecommunications services such as local telephone service to its existing,
well-established base of long distance customers, the Company expects to be
able to increase revenues at relatively low incremental cost. The Company
believes that bundling a variety of telecommunications services and presenting
customers with one fully integrated monthly billing statement for all of those
services will allow it to penetrate its target markets rapidly and build
customer loyalty. The Company believes that there is substantial demand in its
target markets among mid-sized and major regional business customers for an
integrated package of telecommunications services that meets all of their
telecommunications needs.
   
  Leveraging Its Extensive Fiber Optic Network. The Company intends to
leverage its extensive fiber optic network, which currently reaches over 60
POPs, by (i) continuing to provide switched and transport services to other
communications carriers throughout its region to enable such carriers to
diversify their routes and expand their networks; (ii) targeting customers
that need to transmit large amounts of data within the Company's service
region, such as banks and local and state governments; and (iii) offering
local exchange services to its business customers, which began on a limited
basis in the second half of 1997, as part of its integrated package of
telecommunications services. The Company intends initially to provide local
exchange services by reselling the services of incumbent local exchange
carriers and, in some established markets, using its own local switching
facilities. Over time, the Company expects to provide local services primarily
using the Company's own switching facilities and existing regional fiber optic
network, supplemented by unbundled facilities of incumbent local exchange
carriers or other competitive local exchange carriers. The configuration of
the Company's network enables the Company to expand its network by installing
additional remote local switches, which operate in conjunction with the
Company's DMS-500 switches, to provide facilities-based local services.
Because remote local switches are less expensive to purchase and install than
DMS-500 switches, and can be installed more quickly than DMS-500 switches, the
Company believes that it will be able to enter new markets at less expense
than many of its competitors. At present, the Company does not plan to
construct intra-city local loop facilities.     
 
  Focusing on the Southern United States. The Company intends to continue to
focus on the southern United States in order to leverage its extensive
telecommunications network in the region. The Company believes that its
regional focus will enable it to take advantage of economies of scale in
management, network operations and sales and marketing. The regional
concentration of the Company's network also provides an opportunity for
improved margins because a high portion of its customers' telecommunications
traffic originates and terminates within the region. The Company also believes
that its regional focus will enable it to build on its long-standing customer
and business relationships in the region.
 
                                      62

  Building Market Share through Personalized Customer Service. The Company
believes that the key to revenue growth in its target markets is capturing and
retaining customers by emphasizing marketing, sales and customer service.
Management believes that customers prefer one company to be accountable for
their telecommunications services, and that a consultative, face-to-face sales
and service strategy is the most effective method of acquiring and maintaining
a high quality customer base. The Company seeks to obtain long-term
commitments from its business customers by responding rapidly and creatively
to their telecommunications needs. The Company currently operates 14 sales
offices in Alabama, Florida, Georgia, Louisiana, North Carolina and South
Carolina. Each sales office is staffed by personnel capable of marketing all
of the Company's products and providing comprehensive support to the Company's
customers.     
   
  Expanding Its Fiber Optic Network and Switching Facilities. The Company
expects to expand its fiber optic telecommunications network and switching
facilities to include additional markets within the southern United States.
The Company currently owns and operates approximately 2,500 route miles of
fiber optic network extending from Georgia to Texas, with an additional 700
owned and operated route miles expected to be added by the end of 1997 and
approximately 100 owned and operated route mile expected to be added in early
1998. The Company also markets and manages capacity on 2,900 additional
network route miles through its strategic relationships with public utilities.
In addition, the Company has 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 the Company to provide customers with access to
POPs throughout those states. The Company believes that, by continuing to
combine its owned network with the networks of public utilities and by adding
switching facilities throughout its network, it will be able to achieve
capital efficiencies and rapidly expand its network in a cost-effective
manner.     
 
  Leveraging Proven Management Team. The Company's management team consists of
experienced telecommunications managers who in the past have successfully
implemented a customer-focused long distance telecommunications strategy in
the southern United States. Members of the team include Andrew Walker, Chief
Executive Officer of the Company, Foster McDonald, President of the Company,
and Douglas Shumate, Chief Financial Officer of the Company. ITC Holding is
the Company's sole stockholder. The Company anticipates that ITC Holding's
experience and contacts in the telecommunications industry will enhance the
Company's development. See "Risk Factors--Control by ITC Holding Company;
Conflicts of Interest" and "Management."
 
SERVICES AND FACILITIES
 
 Services
 
  The Company currently provides two basic services: (i) Retail Services and
(ii) Carriers' Carrier Services.
   
  Retail Services. Retail Services involve the provision of voice, data or
video telecommunications services to end users or resellers. The Company
currently provides several types of Retail Services, including basic long
distance services (switched, dedicated, and calling card), dedicated Internet
access, data network solutions (frame relay, ATM, point-to-point), and the
sale and installation of customer premise equipment and, in two markets, local
exchange services. The Company intends to provide additional types of Retail
Services in the future and expand the markets in which it offers local
services as part of a bundled "one-stop" integrated telecommunications service
which will offer customers a wide range of switch-based valued-added services.
The Company's customer-focused software and network architecture will permit
the Company to present its customers with one fully integrated monthly billing
statement for the entire package of Retail Services.     
   
  Set forth below are brief descriptions of the Company's Retail Services:
       
    LOCAL SERVICES. The Company intends initially to provide local exchange
  services by reselling the services of incumbent local exchange carriers
  and, in some established markets, using its own local switching facilities.
  Over time, the Company expects to provide local services primarily using
  the Company's own switching facilities and existing regional fiber optic
  network, supplemented by unbundled     
 
                                      63
<PAGE>
 
     
  facilities of incumbent local exchange carriers or other competitive local
  exchange carriers. In July 1997, the Company began offering local services
  in Birmingham and Montgomery, Alabama. The Company expects to offer local
  services as part of its Retail Services in six to nine markets (including
  Birmingham and Montgomery) by the end of 1997.     
          
    In connection with offering local services, the Company has entered into
  the Interconnection Agreement with BellSouth to (i) resell BellSouth's
  local exchange services and (ii) interconnect the Company's network with
  BellSouth's network for the purpose of immediately gaining access to the
  unbundled network elements necessary to provide local exchange services.
  The Interconnection Agreement contains "most favored nation" provisions
  which grant the Company the right to obtain the benefit of any arrangements
  entered into during the term of the Interconnection Agreement between
  BellSouth and any other carrier that materially differ from the rates,
  terms or conditions of the Interconnection Agreement. Under the
  Interconnection Agreement, each party may resell one or more unbundled
  network elements of the other party at agreed upon prices set forth in the
  Interconnection Agreement. In addition, each party is required to pay for
  the interconnection trunks needed to terminate traffic into the other
  party's local network, with the costs of certain two-way interconnection
  trunks and ports to be shared by the Company and BellSouth.     
     
    The Interconnection Agreement has a term of two years beginning July 1,
  1997, and requires the parties to negotiate renewal terms by July 1, 1998
  for interconnection commencing July 1, 1999. In the event the parties fail
  to agree on such terms, they have agreed to operate under the existing
  terms, pending a determination of new terms by a state commission.     
         
    LONG DISTANCE. The Company offers a full range of retail long distance
  services, including traditional switched and dedicated long distance,
  800/888 calling, international, calling card and operator services.
 
    DATA SERVICES. The Company provides high quality data services to its
  customers primarily using frame relay switches distributed strategically
  throughout the Company's network, enabling customers to use a single
  network connection to communicate with multiple sites throughout the
  Company's fiber optic network. The Company currently provides ATM services
  on a resale basis. Beginning in late 1997 or early 1998, the Company
  intends to offer ATM services on its own network, providing data services
  to customers that need to transmit large amounts of data within the
  Company's service region, such as banks and local and state governments.
  The Company will continue to seek, through strategic business relationships
  with other providers, to interconnect its fiber optic network with the
  fiber optic networks of other companies. The Company anticipates increased
  demand for data services in the future, and expects that in the future a
  larger percentage of its revenues will be derived from the sale of
  dedicated data services.
     
    INTERNET ACCESS, INTRANET SERVICES AND WEB DEVELOPMENT. Since its
  acquisition in 1996 of substantially all of the assets of ViperNet, an
  Internet access provider and Web page developer for business customers, the
  Company has provided dedicated (frame relay) Internet access and Intranet
  services, electronic mail, Web page design and Web hosting services. The
  Company expects that mid-sized and larger businesses will require faster
  Internet access and larger bandwidth in the future, and intends to offer
  products that will meet that demand. The Company refers customers
  requesting non-dedicated Internet access to MindSpring Enterprises, Inc.
  ("MindSpring"), an Internet service provider in which ITC Holding has a
  substantial equity interest, and receives a fee per referred customer.     
 
    CUSTOMER PREMISE EQUIPMENT. The Company sells and installs customer
  premise equipment such as telephones, office switchboard systems and, to a
  lesser extent, private branch exchanges (PBX) for customers in the
  Huntsville, Birmingham, Dothan and Montgomery, Alabama markets. The Company
  intends to offer customer premise equipment sales and installation in
  additional markets in the future, with the goals of (i) enhancing and
  supporting the Company's sale of local and long distance services and
  (ii) enhancing customer retention. The Company plans to form relationships
  with local customer premise equipment installation companies in all of its
  markets for the purpose of selling and installing customer premise
  equipment not otherwise provided by the Company.
 
                                      64
<PAGE>
 
  Carriers' Carrier Services. The Company's 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 LATAs. Calls
being transmitted over a long-haul circuit for a customer are generally routed
by the customer through a switch to a receiving terminal in the Company's
network. The Company transmits the signals over a long-haul circuit to the
terminal where the signals are to exit the Company's network. The signals are
then routed by the customer through another switch and to the call recipient
through a local exchange carrier. The Company provides DS-1, DS-3 and OC-N
services. OC-N services are used by the Company's customers for very high
capacity inter-city connectivity and specialized high speed data networking.
The interface between the Company's network and the customer's facilities is
by either local exchange carrier or a direct connection between the Company's
network and the facilities of the customer. The Company typically bills the
customers a fixed monthly rate depending on the capacity and length of the
circuit, regardless of the amount the circuit is actually used.
 
 Facilities
   
  The Company owns or manages approximately 5,400 miles of a high quality
fiber optic network which covers portions of ten states in the southern United
States and extends to over 60 POPs. These POPs are located in almost all major
population centers in the areas covered by the fiber optic network and a
significant number of smaller cities where the Company's only competitor is
the incumbent local exchange carrier.     
   
  The Company owns approximately 2,500 miles of its fiber optic network, which
the Company has built or acquired since 1992. In addition, the Company has
strategic relationships with three public utilities, Duke Power Company,
Florida Power & Light Company and Entergy Technology Company, pursuant to
which the Company markets, sells and manages capacity on approximately 2,900
route miles of network owned and operated by the utilities.     
   
  In addition, the Company is able to purchase network capacity to certain
cities not covered by the Company's owned and managed network in North
Carolina and South Carolina pursuant to 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 at pre-established prices which are generally favorable
to 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.     
   
  The Company expects to add approximately 700 owned and operated route miles
to its fiber network by the end of 1997 and add approximately 100 owned and
operated route miles in early 1998 through long-term dark fiber leases. In
addition, as part of its strategy, the Company intends to continue to evaluate
the potential expansion of its 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.     
   
  The Company's decision to further expand its fiber optic network will be
based on various factors, including: (i) the number of its customers in a
market; (ii) the anticipated operating cost savings associated with such
construction; and (iii) any strategic relationships with owners of existing
infrastructure (e.g., utilities and cable operators). Through its strategic
relationships with public utility companies, the Company believes that it will
be able to achieve capital efficiencies in constructing and expanding its
fiber optic network in a rapid and cost-effective manner. The Company also
believes that its fiber optic network, in combination with its personalized
approach to customer service, will create an attractive customer-focused
platform for the provision of local, long distance and enhanced services.     
       
  The Company has implemented electronic redundancy throughout its 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. Approximately 40%
of the Company's owned and operated fiber optic network is also protected by
geographically diverse routing, a network design (also called a "self healing
ring") which enables traffic to be rerouted to an entirely different fiber
optic cable (assuming capacity is available) in the event of a total cable
cut.
 
                                      65
<PAGE>
 
The Company is continuing to increase the geographic diversity of its fiber
optic network, and expects to have a substantial portion of its network
protected in this manner by the end of 1997.
   
  The Company's switching facilities currently consist of Nortel DMS 500
switches in Birmingham, Alabama and Columbia, South Carolina and a Nortel DMS
250 switch in Arab, Alabama. The Arab switch is capable of handling long
distance switching and the Birmingham and Columbia DMS 500 switches are
capable of handling both local and long distance switching. These
installations enable the Company to market its Retail Services, including
local services, on a switch-based facilities basis in, among other markets,
Huntsville, Birmingham and Montgomery, Alabama; Greenville, Columbia and
Charleston, South Carolina and Atlanta, Georgia. The Company intends to
strategically place additional switches along its fiber network over the next
five years. The Company also intends to deploy a significant number of Nortel
Access Nodes in the majority of the markets which the Company intends to
serve. The additional switches and nodes will allow the Company to perform
local and long distance switching in its markets on a host/remote type
relationship to the applicable DMS 500 switch. The Nortel Access Nodes will be
connected to the Company's DMS 500 switching platform, utilizing the Company's
fiber network wherever possible. This networking design, together with the
Interconnection Agreement, will enable the Company to be a facilities-based
provider of local and long distance services in all of the markets that it
intends to enter. For those markets in which the Company intends to resell the
services of incumbent local exchange carriers, the Company's platform will be
BellSouth's Centrex product, known as MultiServ, which provides full feature
functionality, such as caller identification, call waiting, remote call
forwarding, call blocking, anonymous call rejection and conference calling.
       
  The Company's data network currently consists of six Cascade 9000 frame
relay switches located in Atlanta and West Point, Georgia; Birmingham,
Montgomery and Arab, Alabama; and Columbia, South Carolina. The Company's data
network connects with BellSouth's and Intermedia Communications' frame relay
networks to provide nationwide connectivity for the Company's customers. The
data network currently serves over 105 customers connected to approximately
560 customer locations. The Company's Cascade frame relay switches have the
capability to provide ATM connectivity, and the Company has one ATM connection
to American Communication Services, Inc. for the Internet. The Company intends
to strategically locate additional frame relay and ATM switch sites over the
next five years, with approximately eight to ten frame relay switches being
added in 1997. These frame relay and ATM switches will be co-located with the
Company's DMS-500 switches at strategic network facility locations, and will
create a data backbone which will support the Company's data services.     
 
SALES AND MARKETING
 
  Retail Services
 
  The Company focuses its sales efforts on mid-sized and major regional
businesses in the southern United States. The Company believes that it can
effectively compete for business customers based upon service, product
diversity, price and reliability. The Company's sales force, composed of
direct sales personnel, technical consultants and technicians, markets the
Company's long distance and local communications services. The Company's
management believes that high quality employee training is a prerequisite for
superior customer service, and as a result each member of the Company's sales
force is required to complete the Company's intensive training program. The
Company's marketing strategy is built upon the belief that customers prefer to
hold one company accountable for all of their telecommunications services.
Each sales 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.
   
  Marketing to mid-sized and major regional businesses is currently conducted
by over 70 direct sales personnel (and over 120 other field personnel) located
in 14 sales offices in the southern United States. In the future, the Company
expects to significantly expand its direct sales force and open sales offices
in additional major and secondary population centers in the southern United
States. The Company's sales personnel make direct calls to prospective and
existing business customers, conduct analyses of business customers' usage
    
                                      66
<PAGE>
 
histories and service needs, and demonstrate how the Company's 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. The Company's sales personnel work closely with the
Company's network engineers and information systems consultants to design new
service products and applications. The Company's sales 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 the Company's Retail Services marketing strategy is to
enter into contracts with its 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 the Company's
control, and for certain other defined causes. To date, no customers have been
terminated under these provisions. 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, the Company markets its business communication services through
advertisements, event sponsorships, trade journals, direct mail and trade
forums. Because the Company intends to distinguish its retail products largely
on the convenience of its single communications bundle and the benefits of the
Company's comprehensive, individualized and innovative customer support, the
Company believes that advertising will play a larger role in its marketing
strategy than it has in the past.
 
  Carriers' Carrier Services
   
  The Company has long-haul circuit contracts with major long distance
carriers, including AT&T, MCI, Sprint, WorldCom, Cable & Wireless, LCI,
Frontier and IXC. As of June 30, 1997, on a pro forma basis, the Company had
remaining future long term contract commitments totaling approximately $75.8
million. These contracts expire on various dates through 2006 and are expected
to generate approximately $56.0 million in revenues to the Company through
2001, of which $14.5 million are expected to be realized in 1998. The Company
also provides long-haul transmission to customers after contract expiration on
a month-to-month basis. The Company's long-haul contracts provide for fixed
monthly payments, generally in advance. Although sales volumes from particular
customers vary from year to year, the Company has historically enjoyed high
customer retention and circuit renewal rates.     
 
  The Company believes that it can continue to compete effectively in the
wholesale, carrier-to-carrier market on the basis of price, reliability,
state-of-the-art technology, route diversity, ease of ordering and customer
service. The Company believes that demand for its Carriers' Carrier Services
will increase as the incumbent local exchange carriers begin competing in the
long distance market.
 
COMPETITION
 
  The telecommunications industry is highly competitive. The Company competes
primarily on the basis of price, availability, transmission quality,
reliability, customer service and variety of product offerings. The ability of
the Company to compete effectively will depend on its ability to maintain high
quality services at prices generally equal to or below those charged by its
competitors. In particular, price competition in the retail and carrier's
carrier long distance markets has generally been intense and is expected to
increase. Many of the Company's competitors (such as AT&T, MCI, Sprint and
WorldCom on an interexchange basis and BellSouth on an intraLATA basis) have
substantially greater financial, personnel, technical, marketing and other
resources, larger numbers of established customers and more prominent name
recognition than the Company and utilize more extensive transmission networks
than the Company. In addition, IXC and Qwest Communications International Inc.
are constructing nationwide fiber optic systems, including routes through
portions of the
 
                                      67
<PAGE>
 
   
southern United States. The Company will also increasingly face competition in
the long distance market from local exchange carriers, switchless resellers
and satellite carriers and may eventually compete with public utilities and
cable companies. In particular, Regional Bell Operating Companies such as
BellSouth are now allowed to provide interLATA long distance services outside
their home regions, as well as interLATA mobile services within their regions.
They will be allowed to provide interLATA long distance services within their
regions after meeting certain requirements of the Telecommunications Act
intended to foster opportunities for local telephone competition. The Regional
Bell Operating Companies already have extensive fiber optic cable, switching,
and other network facilities in their respective regions that can be used for
their long distance services. BellSouth and other Regional Bell Operating
Companies are already beginning to take steps toward obtaining approval to
provide in-region long distance services. Although the FCC has not approved
the first two of such applications to come before it, there can be no
assurance that such approvals will be delayed until local competition is
established. In addition, other new competitors may build additional fiber
capacity in the geographic areas served by the Company.     
 
  The Company's principal competitor for local exchange services will be the
incumbent local exchange carrier in the particular market, including BellSouth
in virtually all of the Company's initial market areas. The incumbent local
exchange carriers will enjoy substantial competitive advantages arising from
their historical monopoly position in the local telephone market, including
their preexisting customer relationship with all or virtually all end users.
Furthermore, the Company will be highly dependent on the competing incumbent
local exchange carrier for local network facilities and wholesale services
required in order for the Company to assemble its own local retail products.
The Company will also face competition from competitive local exchange
carriers, some of whom have already established local operations in the
Company's target markets. See "Risk Factors--Dependence on Incumbent Local
Exchange Carriers."
   
  Large long distance carriers, such as AT&T, MCI and Sprint, have begun to
offer local services together with their long distance telecommunications
services in certain markets, and are expected to expand that activity as
opportunities created by the Telecommunications Act develop. In addition,
incumbent local exchange carriers are expected to compete in each other's
markets in some cases. For example, BellSouth has recently announced 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
example, AT&T recently announced plans to offer local services using a new
wireless technology. AT&T's proposed wireless system would link residential
and business telephones via radio waves to the AT&T network. If successful,
this new service could further enhance AT&T's ability to market, on a
nationwide basis, "one-stop" telecommunications services. The Company also
competes with numerous direct marketers and telemarketers and equipment
vendors and installers with respect to certain portions of its business.     
 
  A continuing trend toward consolidation, mergers, acquisitions and strategic
alliances in the telecommunications industry could also increase the level of
competition faced by the Company or the Company's carrier customers. For
example, in December 1996, WorldCom, a national long distance carrier,
acquired MFS Communications Company, Inc., one of the largest competitive
local exchange carriers, and, in November 1996, British Telecommunications plc
announced its agreement to acquire MCI. In March 1997, BellSouth and IBM
announced an alliance to provide Internet and Intranet services to businesses
in the South. The telecommunications market is very dynamic, and additional
competitive changes are likely in the future.
 
REGULATION
 
  Overview. The Company's services are subject to federal, state and local
regulation. The Company, through its wholly owned subsidiaries, holds 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 the Company to obtain licenses, permits or franchises
in order to use the public rights-of-way necessary to install and operate its
networks.
 
  Federal Regulation. The Company is categorized as a non-dominant carrier by
the FCC, and as a result is subject to relatively limited regulation of its
interstate and international services. Certain general policies and rules
apply, as well as certain reporting requirements, but the Company's rates are
not reviewed. The Company has all the authority required by the FCC to conduct
its long distance business. As a non-dominant carrier, the Company may install
and operate additional wireline facilities for the transmission of domestic
interstate communications without prior FCC authorization.
 
  The FCC also imposes prior approval requirements on transfers of control and
assignments of operating authorizations. The FCC has the authority generally
to condition, modify, cancel, terminate or revoke 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 the Company's compliance with applicable laws and regulations.
   
  The FCC also regulates the interstate access rates charged by incumbent
local exchange carriers for the origination and termination of interstate long
distance traffic. Those access rates make up a significant portion of the cost
of providing long distance service. The FCC has recently announced changes to
its interstate access rules that will result in restructuring of the access
charge system and changes in access charge rate levels. These changes will
reduce per-minute access charges and substitute new per-line flat-rate monthly
charges. These actions are expected to reduce access rates, and hence the cost
of providing long distance service, especially to business customers. However,
the full impact of the FCC's new decisions will not be known until those
decisions are implemented over the next several years, during which time those
decisions may be revised. Long distance companies may be disadvantaged if they
have a disproportionate number of customers with multiple local telephone
lines but relatively limited long distance requirements. In addition, AT&T has
committed to reduce its long distance rates to reflect access cost reductions,
and other competitors of the Company are likely to make similar reductions. In
such event, the Company may need to reduce its rates in response to
competitive pressures. 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.     
   
  The Telecommunications Act also gives the FCC a role in establishing rules
for the implementation of local telephone competition, working with the state
PUCs. The Telecommunications Act imposes a variety of new duties on incumbent
local exchange carriers in order to promote competition in local exchange and
access services, and the FCC has authority to develop rules to implement these
duties. Some smaller independent incumbent local exchange carriers may seek
suspension or modification of these obligations, and some companies serving
rural areas are exempt from them.     
   
  In that regard, on August 8, 1996, the FCC adopted the Interconnection
Decision (the "Decision") to implement the interconnection, resale and number
portability provisions of the Telecommunications Act. This Decision
establishes rules pursuant to which incumbent local exchange carriers
interconnect their networks with the networks of competitive local exchange
carriers at rates that are reasonable and non-discriminatory. The Decision
also establishes rules governing the rights of competitive local exchange
carriers to obtain and use elements of the incumbent local exchange carriers'
networks at cost-based rates either to supplement or substitute for
alternative local network facilities that the competitive local exchange
carrier would otherwise be required to install. The Decision sets rules
governing competitive local exchange carrier access to wholesale versions of
the incumbent local exchange carriers' retail local services for resale. The
incumbent local exchange carriers are required to establish administrative
support systems so that these services and functionalities can be made
available to other carriers on a nondiscriminatory basis. The Decision also
created rules to deal with reciprocal compensation for the transport and
termination of local telecommunications, non-discriminatory access to rights
of way, and related matters. A related FCC order adopted the same day
established rules implementing the Telecommunications Act with respect to
local and toll dialing parity among competitors; nondiscriminatory     
 
                                      69

access to telephone numbers, operator services, directory assistance and
listings, network information; and reform of numbering administration.
          
  The FCC's rules were challenged in the federal courts by GTE, the Regional
Bell Operating Companies, large independent incumbent local exchange carriers
and state regulatory commissions. On October 15, 1996, the U.S. Court of
Appeals for the Eighth Circuit issued a stay of the implementation of certain
of the FCC's rules and on July 18, 1997, the Court issued its decision finding
that the FCC lacked statutory authority under the Telecommunications Act for
certain of its rules. In particular, the Court found that the FCC was not
empowered to establish the pricing standards governing unbundled local network
elements or wholesale local services of the incumbent local exchange carriers.
The Court also struck down other FCC rules, including one that would have
enabled new entrants to "pick and choose" from provisions of established
interconnection agreements between the incumbent local exchange carriers and
other carriers. The Court, however, rejected certain other objections to the
FCC rules brought by the incumbent local exchange carriers or the states,
including challenges to the FCC's definition of unbundled elements, and to the
FCC's rules allowing new competitors to create their own networks by combining
incumbent local exchange carrier network elements together without adding
additional facilities of their own. The overall impact of the Court's decision
is to materially reduce the role of the FCC in fostering local competition,
including its ability to take enforcement action if the Telecommunications Act
is violated, and increase the role of state utility commissions. The FCC has
indicated that it will ask the Supreme Court to review the Court's decision.
Meanwhile, certain state commissions have asserted that they will be active in
promoting local telephone competition using the authority they have under the
ruling, which may lessen the significance of the reduced FCC role. At this
time the impact of the Court's decision cannot be evaluated and there can be
no assurance that the Court decision and related developments will not have a
material adverse effect on the Company. Furthermore, other FCC rules related
to local telephone competition remain the subject of legal challenges. For
example, on August 22, 1997, the Eighth Circuit Court issued a second order
striking down certain FCC rules regarding dialing parity for new competitors.
There can be no assurance that these and other pending decisions affecting
local competition will not be adverse to companies seeking to enter the local
telephone market.     
   
  There can be no assurance that the FCC's remaining rules (including such
rules that may be reinstated by the Supreme Court, if any), 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 the Company, have experienced problems with respect to the
operational 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 the Company to provide local
service to customers on a timely and competitive basis. The FCC has recently
created a task force to examine problems that have slowed the development of
local telephone competition.     
   
  The Company has entered into the Interconnection Agreement with BellSouth.
The Interconnection Agreement currently allows the Company to provide local
service on a resale basis or by purchasing all unbundled network elements
required to provide local service on a facilities bases, without using
Company-owned facilities. The Company and BellSouth have agreed on interim
pricing terms for such resale and purchase of unbundled network elements. The
terms of the Interconnection Agreement, including the interim pricing terms,
are subject to the approval of the PUCs regulating the Company's markets. Such
approval has been received from the PUCs of Alabama, Georgia, Kentucky,
Louisiana, Mississippi, North Carolina, South Carolina, Tennessee and is
pending in Florida. In addition, the Interconnection Agreement does not
resolve all operational issues, particularly those relating to the collocation
of the Company's equipment with that of BellSouth. The Company and BellSouth
are continuing to negotiate to resolve such issues. The Company expects that
the Interconnection Agreement will provide a foundation for it to provide
local service on reasonable commercial basis, but there can be no assurance of
this and important issues remain unsettled as a result of the Court decision
and related matters. See "Risk Factors--Dependence on Local Incumbent Exchange
Carriers."     
   
  The Company expects to negotiate similar interconnection agreements with
other incumbent local exchange carriers. However, other carriers who have
preceded the Company 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.     
 
                                      70
<PAGE>
 
   
  As a general matter, no assurance is possible regarding how quickly or how
adequately the Company will be able to take advantage of the opportunities
created by the Telecommunications Act. The Company could be adversely affected
if the court decision reversing some of the new FCC rules, or problems in the
related arbitration and negotiation process, result in increasing the cost of
using incumbent local exchange carrier network elements or services, or if
such actions otherwise result in delays in the implementation of the
Telecommunications Act or impediments to the development of local telephone
competition.     
 
  The Telecommunications Act also imposes certain duties on non-incumbent
local exchange carriers, such as the Company. These duties include the
obligation to complete calls originated by competing carriers under reciprocal
arrangements or through mutual exchange of traffic without explicit payment;
the obligation to permit resale of their telecommunications services without
unreasonable restrictions or conditions; and the duty to provide dialing
parity, number portability, and access to rights of way. The Company does not
anticipate that these obligations will impose a material burden on its
operations. However, given that local telephone competition is still in its
infancy and implementation of the Telecommunications Act has just begun, there
can be no assurance in this regard.
   
  The Telecommunications Act also establishes the foundation for substantial
additional competition to the Company's long distance operations through
elimination or modification of previous prohibitions on the provision of
interLATA long distance services by the Regional Bell Operating Companies and
GTE. The Regional Bell Operating Companies are now permitted to provide
interLATA long distance service outside those states in which they provide
local exchange service ("out-of-region long distance service") upon receipt of
any necessary state and/or federal regulatory approvals that are otherwise
applicable to the provision of intrastate and/or interstate long distance
service. They also are allowed to provide long distance services for their
cellular and other mobile services within the regions in which they also
provide local exchange service ("in-region service"). The Regional Bell
Operating Companies will be allowed to provide wireline in-region services
upon specific approval of the FCC and satisfaction of other conditions,
including a checklist of interconnection requirements. GTE is permitted to
enter the long distance market without regard to limitations by region. GTE is
also subject to the provisions of the Telecommunications Act that impose
interconnection and other requirements on local exchange carriers. BellSouth
and other Regional Bell Operating Companies have begun to take actions
directed towards obtaining authority from the FCC to offer in-region long
distance services in certain of the states in their respective regions.
Although the FCC forced the withdrawal of the first such request, and rejected
the next two, others are anticipated soon. Furthermore, court actions are now
pending challenging both the terms under which the FCC has denied an in-region
application, and the underlying provisions of the Telecommunications Act that
restrict in-region service. There can be no assurance that the Regional Bell
Operating Companies will be prevented from offering in-region long distance
service until local competition is established.     
 
  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 Company anticipates that the FCC will grant incumbent local exchange
carriers increasing pricing flexibility as the number of interconnection
agreements and competitors increases. In a pending rulemaking proceeding
scheduled for completion soon, the FCC is expected to announce new and more
specific policies regarding the conditions and timing under which incumbent
local exchange carriers will be eligible for such increased pricing
flexibility. There can be no assurance that such pricing flexibility will not
place the Company at a competitive disadvantage, either as a purchaser of
access for its long distance operations, or as a vendor of access to other
carriers or end user customers.
 
  State Regulation. The Company is also subject to various state laws and
regulations. Most public utilities commissions require providers such as the
Company to obtain authority from the commission prior to the initiation of
service. In most states, including Alabama, Georgia and Florida, the Company
also is required to file tariffs setting forth the terms, conditions and
prices for services that are classified as intrastate. The Company
 
                                      71
<PAGE>
 
also is required to update or amend its tariffs when it adjusts its rates or
adds new products, and is 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 state utilities commissions or third parties
will not raise issues with regard to the Company's compliance with applicable
laws or regulations.
   
  The Company has all necessary authority to offer intrastate long distance
services in Alabama, Arkansas, California, Colorado, Connecticut, Delaware,
District of Columbia, Florida, Georgia, Idaho, Illinois, Indiana, Iowa,
Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi,
Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New York,
North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Rhode Island, South
Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington,
West Virginia, Wisconsin and Wyoming. The Company is authorized to provide
intrastate long distance service in the states of Arizona and Pennsylvania
while certificates in those states are pending. Applications for authority to
provide intrastate long distance service are also pending in several other
states, including Maine, Minnesota and New Mexico. Applications will be filed,
in the near future, in the states of Alaska and Hawaii. The Company seeks
authority to provide long distance service in states outside of its target
markets to enhance its ability to attract business customers with offices, or
whose employees travel, outside of the Company's target markets. The Company
expects that a penalty will be assessed by the state of Minnesota for
completion of casual intrastate traffic prior to certification. This penalty
is not expected to be significant.     
   
  The Company intends initially to provide local exchange services in its
region by reselling the retail local services of the respective incumbent
local exchange carrier in a given territory and, in some established markets,
using its own local switching facilities. The Company has obtained competitive
local exchange carrier certification in Alabama, Florida, Georgia, Kentucky,
Mississippi, North Carolina, South Carolina and Tennessee. A competitive local
exchange carrier petition for certification is pending in Louisiana.     
 
  Many issues remain open regarding how new local telephone carriers will be
regulated at the state level. For example, although the Telecommunications Act
preempts the ability of states to 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.
   
  The Company also will be heavily affected by state PUC decisions related to
the incumbent local exchange carriers, particularly in view of the July 18,
1997 decision of the Eighth Circuit Court of Appeals noted above which
recognizes a larger role for state utility commissions and a reduced role for
the FCC. For example, PUCs have significant 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 the Company when
necessary. PUCs are considering incumbent local exchange carrier pricing
issues in major proceedings now underway. PUCs will also determine how
competitors can take advantage of the terms and conditions of interconnection
agreements that incumbent local exchange carriers reach with other carriers.
It is too early to evaluate how these matters will be resolved, or their
impact on the ability of the Company to pursue its business plan.     
 
  States also regulate the intrastate carrier access services of the incumbent
local exchange carriers. The Company is required to pay such access charges to
originate and terminate its intrastate long distance traffic. The Company
could be adversely affected by high access charges, particularly to the extent
that the incumbent
 
                                      72
<PAGE>
 
local exchange carriers do not incur the same level of costs with respect to
their own intrastate long distance services. A related 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. It is unclear whether state
utility commissions will adopt changes in their rules governing intrastate
access charges similar to those recently approved by the FCC for interstate
access. The Company's business could be adversely affected by such changes.
   
  The Company also will be affected by how states regulate the retail prices
of the incumbent local exchange carriers with which it competes. The Company
believes 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 the
Company's 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. The Company cannot predict
the extent to which this may occur or its impact on the Company's business.
    
       
       
  Local Government Authorizations. The Company is required to obtain street
use and construction permits and licenses and/or franchises to install and
expand its fiber optic networks using municipal rights-of-way. In some
municipalities where the Company has installed or anticipates constructing
networks, it 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 the Company, although the
Telecommunications Act requires that in the future such fees be applied in a
competitively neutral manner. To the extent that, notwithstanding the Act,
competitors do not pay the same level of fees as the Company, the Company
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 the Company remove
its facilities or abandon its network in place could have a material adverse
effect on the Company.
 
  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 the
Company and its business plan. No assurance can be given that future
regulatory developments will not have a materially adverse impact on the
Company.
 
FACILITIES, REAL PROPERTY AND LEASES
   
  The Company leases its corporate headquarters space in West Point, Georgia
from ITC Holding. The lease expires in 2005 and may be terminated by either
party on 90 days' notice. See "Certain Transactions--ITC Holding." The Company
also owns a switch site in Birmingham, Alabama and leases space for a network
operations center and a switch site in Arab, Alabama. In addition, the Company
intends to construct a multi-service facility in Anniston, Alabama to function
as a centralized switching control center for the Company's network and an
operator services center. Construction of the Anniston facility is expected to
commence by the end of 1997 and to be completed in the second quarter of 1998.
       
  The Company operates sales offices in Atlanta (two offices), Georgia;
Pensacola, Florida; Columbia and Greenville, South Carolina; Charlotte, North
Carolina; New Orleans and Baton Rouge, Louisiana; and Huntsville, Mobile,
Auburn, Dothan, Florence, Montgomery and Birmingham, Alabama. The leases for
these offices expire between 1997 and 2001.     
 
  As part of its fiber optic network and switched service system, the Company
owns or leases rights-of-way, land, office space and towers throughout the
southern United States.
 
  The Company owns land and microwave transmission towers at various locations
in Alabama.
 
                                      73
<PAGE>
 
  The Company expects to lease or purchase additional office space and
switching and other network facilities in connection with the planned
expansion of its telecommunications network system.
 
  The Company believes that all of its properties are well maintained.
 
EMPLOYEES
   
  As of June 30, 1997, the Company had over 500 full-time employees, none of
whom was represented by a union or covered by a collective bargaining
agreement. The Company believes that its relationship with its employees is
good. In connection with the construction and maintenance of its fiber optic
network and the conduct of its other business operations, the Company uses
third party contractors, some of whose employees may be represented by unions
or covered by collective bargaining agreements.     
 
LEGAL PROCEEDINGS
 
  In May 1997, the U.S. District Court for the Middle District of Alabama,
Southern Division returned a verdict against DeltaCom in Digitel Corporation
v. DeltaCom, Inc., Richard A. Wilkins, John A.R. Smith, and Edward L.
Blackwell, awarding plaintiff $265,000 in damages. Plaintiff in this action
alleged that certain of its former employees violated the non-solicitation
agreements they had entered into with plaintiff as part of their employment.
Plaintiff further alleged that DeltaCom, as the current employer of these
former employees, shares liability for their alleged violations. DeltaCom is
indemnified by the former stockholders of DeltaCom against both the attorney's
fees incurred in defending the action and the judgment resulting from the
action.

INCENTIVE COMPENSATION PLANS

as "incentive stock options" under Section 422 of the Internal Revenue Code of
1986, as amended (the "Code"), to employees of the Company, its subsidiaries
and its parent corporation, 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 1,500,000 shares of Class A
Common Stock pursuant to options granted under the Stock Option Plan (subject
to anti-dilution adjustments in the event of a stock split, recapitalization
or similar transaction). The maximum number of shares subject to options that

Option Plan and will grant options to purchase Class A 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
Class A 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 Class A 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 Class A Common Stock on the date of grant of
the option. The maximum option term is ten years (or five years in the case of
an incentive stock option granted to an optionee beneficially owning more than
10% of the outstanding Class A Common Stock). Options may be exercised at any
time after grant, except as otherwise provided in the particular option
agreement. There is also a $100,000 limit on the value of Class A 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 Board of Directors may amend or terminate the Stock Option Plan with
respect to shares of Class A Common Stock as to which options have not been
granted.
   
  At July 31, 1997, options to purchase 894,254 shares of Class A Common Stock
were outstanding pursuant to the Stock Option Plan.     
 
  Directors Stock Option Plan. The Company's 1997 Directors Stock Option Plan
(the "Directors 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, ITC Holding or any subsidiary of the Company (each an "Eligible
Director"). The Directors Plan authorizes the issuance of up to 150,000 shares
of Class A Common Stock pursuant to options granted under the Directors Plan
(subject to anti-dilution adjustments in the event of a stock split,
recapitalization or similar transaction). The option exercise price for
options granted under the Directors Plan will be 100% of the fair market value
of the shares of Class A Common Stock on the date of grant of the option.

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. The Board of Directors may amend or terminate the Directors
Plan with respect to shares of Class A Common Stock as to which options have
not been granted.

  The Company has adopted a policy requiring that any material transactions
between the Company and persons or entities affiliated with officers,

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
SCANA NOTE
   
  The SCANA Note has been assumed by Interstate FiberNet, Inc., which became a
wholly owned subsidiary of the Company as part of the Reorganization. See
"History of the Company--Reorganization." The SCANA Note, which has a
principal balance of approximately $10.0 million, has a maturity date of March
31, 2002. Interest accrues on the SCANA Note at an annual rate of 11% and is
payable semiannually in arrears. Principal is payable semiannually, commencing
on September 30, 1997, in equal semiannual installments of $996,409. The SCANA
Note is unsecured.     
 
CREDIT FACILITY
   
  Interstate FiberNet, Inc. (the "Borrower"), has entered into the Commitment
Letter with NationsBank, pursuant to which NationsBank has agreed, subject to
the terms and conditions set forth in the Commitment Letter (including the
negotiation of definitive loan documents), to provide a Credit Facility of up
to $100 million to the Borrower to be used for working capital and other
purposes, including capital expenditures and permitted acquisitions.     
 
  The following summary of the material provisions of the Commitment Letter
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, the Commitment Letter, a copy of which is available
from the Company upon request. Defined terms that are used but not defined in
this section have the meanings given to such terms in the Commitment Letter.
Because the terms, conditions and covenants of the Credit Facility are subject
to the negotiation, execution and delivery of the definitive loan documents,
certain of the actual terms, conditions and covenants thereof may differ from
those described below.
 
  The Credit Facility will mature on the fifth anniversary of its closing. The
Credit Facility will include a $50 million multi-draw term loan facility and a
$50 million revolving credit facility. The Company may draw down amounts under
the term loan facility until the second anniversary of the Credit Facility and
must draw down the full amount of this facility before drawing down any amount
over $10 million under the revolving credit facility.
 
  Amounts drawn under the Credit Facility will bear interest, at the
Borrower's option, at either the Base Rate or the Eurodollar Rate, plus an
Applicable Margin. The Applicable Margin will be an annual rate which will
fluctuate based on the Borrower's Total Leverage Ratio (as defined below) and
which will be between 1.75% and .75% for Base Rate borrowings and between
2.75% and 1.75% for the Eurodollar Rate borrowings.
 
  The Commitment Letter contemplates that the Borrower will be required to
repay indebtedness outstanding under the Credit Facility with the net cash
proceeds from sales of assets other than in the ordinary course of business
and from certain issuances of equity securities by the Borrower or
ITC/\DeltaCom.
 
  The Commitment Letter contemplates that the Borrower's obligations under the
Credit Facility will be guaranteed by the Company and the Borrower's
subsidiaries and will be secured by a first priority lien on all current and
future assets and properties of the Borrower and its subsidiaries and a first
priority pledge of the stock of the Borrower and its subsidiaries.
 
  The Commitment Letter contemplates that the Credit Facility will contain a
number of covenants, including, among others, covenants limiting the ability
of the Borrower, the Borrower's present and future subsidiaries and
ITC/\DeltaCom to incur debt, create liens, pay dividends, make distributions or
stock repurchases, make investments or capital expenditures, change their
business, engage in transactions with affiliates, sell assets and engage in
mergers and acquisitions. In addition, the Commitment Letter contemplates that
the Credit Facility will contain affirmative covenants, including, among
others, covenants requiring compliance with laws, maintenance of corporate
existence, licenses and insurance, payment of taxes and performance of other
material obligations and the delivery of financial and other information.
 
                                      83
<PAGE>
 
  The Commitment Letter contemplates that the Credit Facility will restrict
the Borrower from declaring and paying dividends or distributions, including
dividends to pay scheduled interest on the Exchange Notes. However, the
Borrower will be permitted to pay dividends to ITC/\DeltaCom to pay scheduled
interest on the Exchange Notes, commencing after the sixth scheduled interest
payment, unless at the time of such dividend or distribution an event of
default (other than an event of default resulting solely from the breach of a
representation or warranty) under the Credit Facility exists or would be
caused by such dividend or distribution; provided that, with respect to any
event of default (other than a payment default, a bankruptcy event with
respect to ITC/\DeltaCom or the Borrower or the loss of a material license or
fiber network), the Borrower will not be prohibited from paying dividends to
ITC/\DeltaCom to pay scheduled interest on the Exchange Notes for more than 180
days.
 
  The Commitment Letter also contemplates that the Company will be required to
comply with certain financial tests and to maintain certain financial ratios
on a consolidated basis. The Company must maintain (i) a Total Leverage Ratio
no greater than 9.5:1.0 initially, with subsequent reductions, (ii) a Senior
Leverage Ratio no greater than 2.75:1.0 initially, with subsequent reductions,
and (iii) an Interest Coverage Ratio no less than 3.75:1.0 through June 30,
2000 and 1.75:1.0 thereafter. Total Leverage Ratio means at any date, for the
Company on a consolidated basis, the ratio of Total Debt on such date to
Annualized Operating Cash Flow of the Company on a consolidated basis. Total
Debt means the aggregate indebtedness of the Company for borrowed money on a
consolidated basis, net of cash balances in excess of $5 million plus, except
for purposes of calculating the Senior Leverage Ratio, the balance of Pledged
Securities securing the Senior Notes and the Exchange Notes. Annualized
Operating Cash Flow means Operating Cash Flow for the six-month period most
recently ended multiplied by two. Operating Cash Flow for any period means the
consolidated net income (loss) of the Company for such period plus the
following amounts for such period, to the extent included in the determination
of such income (loss): depreciation expense, amortization expense and other
non-cash charges reducing income, net interest expense, and tax expense.
Senior Leverage Ratio means, for the Company on a consolidated basis at any
date, the ratio of Senior Debt (Total Debt minus the Senior Notes and the
Exchange Notes) to Annualized Operating Cash Flow of the Company on a
consolidated basis. Interest Coverage Ratio means, for the Company on a
consolidated basis for any period, the ratio of Operating Cash Flow to the
aggregate amount of interest due and payable by the Company with respect to
Total Debt during such period net of interest on the Senior Notes and the
Exchange Notes funded by Pledged Securities and up to $9.3 million of interest
paid to ITC Holding at the closing of the Credit Facility.
 
  Failure to satisfy any of the financial covenants would constitute an Event
of Default under the Credit Facility, notwithstanding the ability of the
Borrower to meet its debt service obligations. The Commitment Letter also
contemplates that the Credit Facility also will include other customary events
of default, including, without limitation, a cross-default to other
indebtedness, material undischarged judgments, bankruptcy and a change of
control.

                       DESCRIPTION OF THE EXCHANGE NOTES
 
  The Senior Notes were, and the Exchange Notes will be, issued under the
Indenture, dated as of June 3, 1997, between the Company and United States
Trust Company of New York, trustee under the Indenture (the "Trustee"). A copy
of the Indenture is filed as an exhibit to the Registration Statement (of
which this Prospectus is a part). The following summary contains a description
of certain provisions of the Indenture, but does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all of
the provisions of the Indenture, including the definitions of certain terms
therein and those terms made a part thereof by the Trust Indenture Act of
1939, as amended. For definitions of certain capitalized terms used in the
following summary, see "--Certain Definitions."
 
GENERAL
 
  The terms of the Exchange Notes will be identical in all material respects
to the Senior Notes, except that (i) the Exchange Notes will have been
registered under the Securities Act and therefore will not be subject to
certain restrictions on transfer applicable to the Senior Notes and (ii)
Holders of the Exchange Notes will not be entitled to certain rights of
Holders of Senior Notes under the Registration Rights Agreement.
 
  The Exchange Notes will be unsecured (except to the extent described under
"--Security" below) unsubordinated obligations of the Company, initially
limited to $200,000,000 aggregate principal amount, and will mature on June 1,
2007. Each Exchange Note will bear interest at the rate of 11% per annum from
the Closing Date or from the most recent Interest Payment Date to which
interest has been paid or provided for, payable semiannually (to Holders of
record at the close of business on the May 15 or November 15 immediately
preceding the Interest Payment Date) on June 1 and December 1, of each year,
commencing December 1, 1997.
 
  Principal of, premium, if any, and interest on the Exchange Notes will be
payable, and the Exchange Notes may be exchanged or transferred, at the office
or agency of the Company in the Borough of Manhattan, The City of New York
(which initially will be the corporate trust office of the Trustee at 114 West
47th Street, New York, New York 10036-1532); provided that, at the option of
the Company, payment of interest may be made by check mailed to the Holders at
their addresses as they appear in the Security Register.
 
  The Exchange Notes will be issued only in fully registered form, without
coupons, in denominations of $1,000 of principal amount and any integral
multiple thereof. See "--Book-Entry; Delivery and Form." No service charge
will be made for any registration of transfer or exchange of Exchange Notes,
but the Company may require payment of a sum sufficient to cover any transfer
tax or other similar governmental charge payable in connection therewith.
 
  Subject to the covenants described below under "Covenants" and applicable
law, the Company may issue additional Notes under the Indenture. The Exchange
Notes offered hereby and any additional Notes subsequently issued would be
treated as a single class for all purposes under the Indenture.
 
OPTIONAL REDEMPTION
 
  The Exchange Notes will be redeemable, at the Company's option, in whole or
in part, at any time or from time to time, on or after June 1, 2002 and prior
to maturity, upon not less than 30 nor more than 60 days' prior notice mailed
by first class mail to each Holder's last address, as it appears in the
Security Register, at the following Redemption Prices (expressed in
percentages of principal amount), plus accrued and unpaid interest to the
Redemption Date (subject to the right of Holders of record on the relevant
Regular Record Date that is prior to the Redemption Date to receive interest
due on an Interest Payment Date), if redeemed during the 12-month period
commencing June 1, of the years set forth below:

</TABLE>
 
                                      85
<PAGE>
 
  In addition, at any time prior to June 1, 2000, the Company may redeem up to
35% of the principal amount of the Senior Notes and the Exchange Notes with
the proceeds of one or more Public Equity Offerings following which a Public
Market occurs, at any time or from time to time in part, at a Redemption Price
(expressed as a percentage of principal amount) of 111%, plus accrued and
unpaid interest to the Redemption Date (subject to the rights of Holders of
record on the relevant Regular Record Date that is prior to the Redemption
Date to receive interest due on an Interest Payment Date); provided that at
least $130.0 million aggregate principal amount of Senior Notes and the
Exchange Notes remains outstanding after each such redemption.
 
  If less than all of the Notes are to be redeemed at any time, the Trustee
will select the Notes, or portions thereof, for redemption in compliance with
the requirements of the principal national securities exchange, if any, on
which the Notes are listed or, if the Notes are not listed on a national
securities exchange, on a pro rata basis, by lot or by such other method as
the Trustee in its sole discretion shall deem to be fair and appropriate;
provided that no Note of $1,000 in principal amount or less shall be redeemed
in part. If any Note is to be redeemed in part only, the notice of redemption
relating to such Note shall state the portion of the principal amount thereof
to be redeemed. A new Note in principal amount equal to the unredeemed portion
thereof will be issued in the name of the Holder thereof upon cancellation of
the original Note.
       
SECURITY
   
  The Indenture requires that a portion of the proceeds from the Offering
remain subject to the Pledge Agreement and be invested in Pledged Securities
in such amounts and maturities as will be sufficient upon receipt of scheduled
interest and principal payments of such securities, in the opinion of a
nationally recognized firm of independent public accountants selected by the
Company, to provide for payment in full of the first six scheduled interest
payments due on the Senior Notes and the Exchange Notes. Approximately $62.7
million of such proceeds are held by the Trustee as security for and to fund
the first six interest payments on the Senior Notes and the Exchange Notes.
    
   
  The Pledged Securities are pledged to the Trustee for the benefit of the
Holders of the Senior Notes and the Exchange Notes pursuant to the Pledge
Agreement and are being held by the Trustee in the Pledge Account. Pursuant to
the Pledge Agreement, immediately prior to an Interest Payment Date, the
Company may either deposit with the Trustee from funds otherwise available to
the Company cash sufficient to pay the interest scheduled to be paid on such
date or the Company may direct the Trustee to release from the Pledge Account
proceeds sufficient to pay interest then due on the Senior Notes and the
Exchange Notes. A failure to pay interest on the Senior Notes or the Exchange
Notes in a timely manner through the first six scheduled interest payment
dates will constitute an immediate Event of Default under the Indenture, with
no grace or cure period. The Pledged Securities and Pledge Account will also
secure the repayment of the principal amount and premium on the Senior Notes
and the Exchange Notes.     
 
  Under the Pledge Agreement, once the Company makes the first six scheduled
interest payments on the Exchange Notes, all of the remaining Pledged
Securities, if any, will be released from the Pledge Account and thereafter
the Exchange Notes will be unsecured.
 
EXCHANGE OFFER; REGISTRATION RIGHTS
 
  The Company entered into the Registration Rights Agreement with the
Placement Agents, for the benefit of the holders of Senior Notes, pursuant to
which the Company agreed to file the Registration Statement (of which this
Prospectus is a part) with the Commission. The Registration Rights Agreement
provides that the Company will, at its cost, use its best efforts to cause the
Registration Statement to be filed with the SEC not later than 60 days after
the Closing Date (as defined in the Purchase Agreement attached as an exhibit
to the Registration Statement of which this Prospectus is a part) and declared
effective under the Securities Act. Upon the effectiveness of the Registration
Statement, the Company will offer the Exchange Notes in exchange for surrender
of the Senior Notes. The Company has agreed to keep the Exchange Offer open
for not less than 20 days after the date notice of the Exchange Offer is
mailed to the holders of Senior Notes. For each Senior Note
 
                                      86
<PAGE>
 
surrendered to the Company pursuant to the Exchange Offer, the holder of such
Senior Note will receive an Exchange Note having a principal amount equal to
that of the surrendered Senior Note. Under existing Commission
interpretations, the Exchange Notes would be freely transferable by holders
other than affiliates of the Company after the Exchange Offer without further
registration under the Securities Act if the holder of the Exchange Notes
represents that it is acquiring the Exchange Notes in the ordinary course of
its business, that it has no arrangement or understanding with any person to
participate in the distribution of the Exchange Notes and that it is not an
affiliate of the Company, as such terms are interpreted by the Commission;
provided that broker-dealers ("Participating Broker-Dealers") receiving
Exchange Notes in the Exchange Offer will have a prospectus delivery
requirement with respect to resales of such Exchange Notes. The Commission has
taken the position that Participating Broker-Dealers may fulfill their
prospectus delivery requirements with respect to Exchange Notes with the
prospectus contained in the Registration Statement under certain
circumstances. Under the Registration Rights Agreement, the Company is
required to allow Participating Broker-Dealers and other persons, if any, with
similar prospectus delivery requirements to use this Prospectus in connection
with the resale of such Exchange Notes.
 
  A holder of Senior Notes who wishes to exchange such Senior Notes for
Exchange Notes in the Exchange Offer will be required to represent that, among
other things, any Exchange Notes to be received by it will be acquired in the
ordinary course of its business and that at the time of the commencement of
the Exchange Offer it has no arrangement or understanding with any person to
participate in a distribution (within the meaning of the Securities Act) of
the Exchange Notes and that it is not an "affiliate" of the Company, as
defined in Rule 405 of the Securities Act, or if it is an affiliate, that it
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable.
 
  The Company has filed the Registration Statement (of which this Prospectus
is a part) and will commence the Exchange Offer pursuant to the Registration
Rights Agreement. In the event that applicable interpretations of the staff of
the Commission do not permit the Company to effect the Exchange Offer, or
under certain other circumstances, the Company has agreed, at its cost, to use
its best efforts to file and cause to become effective a shelf registration
statement (the "Shelf Registration Statement") with respect to resales of the
Senior Notes and to keep the Shelf Registration Statement effective until the
expiration of the time period referred to in Rule 144(k) under the Securities
Act or such shorter period that will terminate when all Senior Notes covered
by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement. The Company has agreed, in the event a Shelf
Registration Statement is filed, among other things, to provide to each holder
for whom such Shelf Registration Statement was filed copies of the prospectus
which is a part of the Shelf Registration Statement, to notify each such
holder when the Shelf Registration Statement has become effective and to take
certain other actions as are required to permit unrestricted resales of the
Senior Notes. A holder selling such Senior Notes pursuant to the Shelf
Registration Statement generally would be required to be named as a selling
security holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Rights Agreement which are applicable to such
holder (including certain indemnification obligations).
 
  In the event the Exchange Offer is not consummated and a Shelf Registration
Statement is not declared effective on or prior to the date that is six months
after the Closing Date, the interest rate on the Senior Notes will be
increased by .5% per annum until the Exchange Offer is consummated or the
Shelf Registration is declared effective.
 
  Senior Notes not tendered in the Exchange Offer shall accrue interest at the
rate of 11% per annum and be subject to all of the terms and conditions
specified in the Indenture and to the transfer restrictions described in
"Transfer Restrictions."
 
  This summary of certain provisions of the Registration Rights Agreement does
not purport to be complete and is subject to, and is qualified in its entirety
by reference to, all the provisions of the Registration Rights

<PAGE>
 
Agreement, a copy of which has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part.
 
RANKING
   
  The Indebtedness evidenced by the Exchange Notes will rank pari passu in
right of payment with the Senior Notes and all other existing and future
unsubordinated indebtedness of the Company and senior in right of payment to
all existing and future subordinated indebtedness of the Company. After giving
pro forma effect to the Reorganization, as of June 30, 1997, the Company would
have had no indebtedness outstanding other than the Senior Notes and the
Exchange Notes. The Company is permitted to incur additional indebtedness to
finance the acquisition of equipment, inventory and network assets and up to
$100 million of other indebtedness and is permitted to secure any such
indebtedness. The Exchange Notes will be effectively subordinated to such
security interests to the extent of such security interests.     
   
  The Company is a holding company which conducts substantially all of its
business through subsidiaries. The Company's subsidiaries will have no direct
obligation to pay amounts due on the Senior Notes and the Exchange Notes and
will not guarantee the Senior Notes and the Exchange Notes. As a result, the
Senior Notes and, the Exchange Notes will be, effectively subordinated to all
existing and future indebtedness and other liabilities (including trade
payables) of the Company's subsidiaries. After giving pro forma effect to the
Reorganization, as of June 30, 1997, the Company's subsidiaries would have had
approximately $37.7 million of liabilities (excluding intercompany payables),
including approximately $14.4 million of indebtedness (including capital
leases). The Company will be dependent upon access to the cash flow or assets
of its subsidiaries to make payments on the Exchange Notes and the Company's
ability to obtain such access may be limited by law. See "Risk Factors--
Holding Company Structure; Priority of Secured Debt."

existing on the Closing Date); provided that the Company may Incur
Indebtedness if, after giving effect to the Incurrence of such Indebtedness

than to the Company or another Restricted Subsidiary) shall be deemed, in each
case, to constitute an Incurrence of such Indebtedness not permitted by this
clause (ii); (iii) Indebtedness issued in exchange for, or the net proceeds of
which are used to refinance or refund, then outstanding Indebtedness (other
than Indebtedness Incurred under clause (i), (ii), (iv), (vi) or (ix) of this
paragraph) and any refinancings of such new Indebtedness in an amount not to

in part or the Indebtedness to be refinanced is pari passu in right of payment
with the Notes, such new Indebtedness, by its terms or by the terms of any

outstanding, is expressly made pari passu in right of payment with, or
subordinate in right of payment to, the remaining Notes, (B) in case the
Indebtedness to be refinanced is subordinated in right of payment to the
Notes, such new Indebtedness, by its terms or by the terms of any agreement or

no event may Indebtedness of the Company be refinanced by means of any
Indebtedness of any Restricted Subsidiary pursuant to this clause (iii); (iv)
Indebtedness (A) in respect of performance, surety or appeal bonds provided in
the ordinary course of business, (B) under Currency Agreements and Interest
Rate Agreements; provided that such agreements (a) are designed solely to

currency exchange rates or interest rates and (b) do not increase the
Indebtedness of the obligor outstanding at any time other than as a result of
fluctuations in foreign currency exchange rates or interest rates or by reason
of fees, indemnities and compensation payable thereunder or (C) arising from
agreements providing for indemnification, adjustment of purchase price or
similar obligations, or from Guarantees or letters of credit, surety bonds or

existing under or by reason of applicable law; (iii) existing with respect to
any Person or the property or assets of such Person acquired by the Company or

directly or indirectly, to issue or sell, any shares of Capital Stock of a
Restricted Subsidiary (including options, warrants or other rights to purchase
shares of such Capital Stock) except (i) to the Company or a Wholly Owned
Restricted Subsidiary, (ii) issuances of director's qualifying shares, or
sales to foreign nationals of shares of Capital Stock of foreign Restricted
Subsidiaries, to the extent required by applicable law, (iii) if, immediately
after giving effect to such issuance or sale, such Restricted Subsidiary would
no longer constitute a Restricted Subsidiary and any Investment in such Person
remaining after giving effect to such issuance or sale would have been
permitted to be made under the "Limitation on Restricted Payments" covenant if
made on the date of such issuance or sale or (iv) issuances or sales of Common
Stock of a Restricted Subsidiary, provided that the Company or such Restricted
Subsidiary applies the Net Cash Proceeds, if any, of any such sale in
accordance with clause (A) or (B) of the "Limitation on Asset Sales" covenant
described below.
 
  Limitation on Issuances of Guarantees by Restricted Subsidiaries
 
  The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company which is pari passu
in right of payment with, or subordinate in right of payment
 
                                      103

to, the Notes ("Guaranteed Indebtedness"), unless (i) such Restricted
Subsidiary simultaneously executes and delivers a supplemental indenture to
the Indenture providing for a Guarantee (a "Subsidiary Guarantee") of payment
of the Notes by such Restricted Subsidiary and (ii) such Restricted Subsidiary
waives, and will not in any manner whatsoever claim or take the benefit or
advantage of, any rights of reimbursement, indemnity or subrogation or any
other rights against the Company or any other Restricted Subsidiary as a
result of any payment by such Restricted Subsidiary under its Subsidiary
Guarantee; provided that this paragraph shall not be applicable to (x) any
Guarantee of any Restricted Subsidiary that existed at the time such Person
became a Restricted Subsidiary and was not Incurred in connection with, or in
contemplation of, such Person becoming a Restricted Subsidiary or (y) any
Guarantee of any Restricted Subsidiary of Indebtedness Incurred (I) under
Credit Facilities pursuant to clause (i) of the second paragraph of the
"Limitation on Indebtedness" covenant or (II) pursuant to clause (vii) of the
second paragraph of the "Limitation on Indebtedness" covenant. If the
Guaranteed Indebtedness is (A) pari passu in right of payment with the Notes,
then the Guarantee of such Guaranteed Indebtedness shall be pari passu in
right of payment with, or subordinated in right of payment to, the Subsidiary
Guarantee or (B) subordinated in right of payment to the Notes, then the
Guarantee of such Guaranteed Indebtedness shall be subordinated in right of
payment to the Subsidiary Guarantee at least to the extent that the Guaranteed
Indebtedness is subordinated in right of payment to the Notes.
 
  Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or
transfer, to any Person not an Affiliate of the Company, of all of the
Company's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, such Restricted Subsidiary (which sale,
exchange or transfer is not prohibited by the Indenture) or (ii) the release
or discharge of the Guarantee which resulted in the creation of such
Subsidiary Guarantee, except a discharge or release by or as a result of
payment under such Guarantee.
 
  Limitation on Transactions with Stockholders and Affiliates
 
  The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction
(including, without limitation, the purchase, sale, lease or exchange of
property or assets, or the rendering of any service) with any holder (or any
Affiliate of such holder) of 5% or more of any class of Capital Stock of the
Company or with any Affiliate of the Company or any Restricted Subsidiary,
except upon fair and reasonable terms no less favorable in any material
respect to the Company or such Restricted Subsidiary than could be obtained,
at the time of such transaction or, if such transaction is pursuant to a
written agreement, at the time of the execution of the agreement providing
therefor, in a comparable arm's-length transaction with a Person that is not
such a holder or an Affiliate.
 
  The foregoing limitation does not limit, and shall not apply to: (i)
transactions (A) approved by a majority of the disinterested members of the
Board of Directors or (B) for which the Company or a Restricted Subsidiary
delivers to the Trustee a written opinion of a nationally recognized
investment banking firm stating that the transaction is fair to the Company or
such Restricted Subsidiary from a financial point of view; (ii) any
transaction solely between the Company and any of its Wholly Owned Restricted
Subsidiaries or solely between Wholly Owned Restricted Subsidiaries; (iii) the
payment of reasonable and customary regular fees to directors of the Company
who are not employees of the Company; (iv) any payments or other transactions
pursuant to any tax-sharing agreement between the Company and any other Person
with which the Company files a consolidated tax return or with which the
Company is part of a consolidated group for tax purposes; (v) any Restricted
Payments not prohibited by the "Limitation on Restricted Payments" covenant;
or (vi) the Reorganization. Notwithstanding the foregoing, any transaction
covered by the first paragraph of this "Limitation on Transactions with
Stockholders and Affiliates" covenant and not covered by clauses (ii) through
(vi) of this paragraph, the aggregate amount of which exceeds $5 million in
value, must be approved or determined to be fair in the manner provided for in
clause (i)(A) or (B) above.
 
 
                                      104

  Limitation on Liens
 
  The Company will not, and will not permit any Restricted Subsidiary to,
create, incur, assume or suffer to exist any Lien on any of its assets or
properties of any character, or any shares of Capital Stock or Indebtedness of
any Restricted Subsidiary, without making effective provision for all of the
Notes and all other amounts due under the Indenture to be directly secured
equally and ratably with (or, if the obligation or liability to be secured by
such Lien is subordinated in right of payment to the Notes, prior to) the
obligation or liability secured by such Lien.
 
  The foregoing limitation does not apply to: (i) Liens existing on the
Closing Date; (ii) Liens granted after the Closing Date on any assets or
Capital Stock of the Company or its Restricted Subsidiaries created in favor
of the Holders; (iii) Liens with respect to the assets of a Restricted
Subsidiary granted by such Restricted Subsidiary to the Company or a Wholly
Owned Restricted Subsidiary to secure Indebtedness owing to the Company or
such other Restricted Subsidiary; (iv) Liens securing Indebtedness which is
Incurred to refinance secured Indebtedness which is permitted to be Incurred
under clause (iii) of the second paragraph of the "Limitation on Indebtedness"
covenant; provided that such Liens do not extend to or cover any property or
assets of the Company or any Restricted Subsidiary other than the property or
assets securing the Indebtedness being refinanced; (v) Liens securing
obligations under Credit Facilities Incurred under clause (i) of the second
paragraph of the "Limitation on Indebtedness" covenant; or (vi) Permitted
Liens.
 
  Limitation on Sale-Leaseback Transactions
 
  The Company will not, and will not permit any Restricted Subsidiary to,
enter into any sale-leaseback transaction involving any of its assets or
properties whether now owned or hereafter acquired, whereby the Company or a
Restricted Subsidiary sells or transfers such assets or properties and then or
thereafter leases such assets or properties or any part thereof or any other
assets or properties which the Company or such Restricted Subsidiary, as the
case may be, intends to use for substantially the same purpose or purposes as
the assets or properties sold or transferred.
 
  The foregoing restriction does not apply to any sale-leaseback transaction
if (i) the lease is for a period, including renewal rights, of not in excess
of three years; (ii) the lease secures or relates to industrial revenue or
pollution control bonds; (iii) the transaction is solely between the Company
and any Wholly Owned Restricted Subsidiary or solely between Wholly Owned
Restricted Subsidiaries; or (iv) the Company or such Restricted Subsidiary,
within 12 months after the sale or transfer of any assets or properties is
completed, applies an amount not less than the net proceeds received from such
sale in accordance with clause (A) or (B) of the first paragraph of the
"Limitation on Asset Sales" covenant described below.
 
  Limitation on Asset Sales
 
  The Company will not, and will not permit any Restricted Subsidiary to,
consummate any Asset Sale, unless (i) the consideration received by the
Company or such Restricted Subsidiary is at least equal to the fair market
value of the assets sold or disposed of and (ii) at least 75% of the
consideration received consists of cash or Temporary Cash Investments. In the
event and to the extent that the Net Cash Proceeds received by the Company or
any of its Restricted Subsidiaries from one or more Asset Sales occurring on
or after the Closing Date in any period of 12 consecutive months exceed 10% of
Adjusted Consolidated Net Tangible Assets (determined as of the date closest
to the commencement of such 12-month period for which a consolidated balance
sheet of the Company and its Subsidiaries has been filed with the Commission
or provided to the Trustee pursuant to the "Commission Reports and Reports to
Holders" covenant), then the Company shall or shall cause the relevant
Restricted Subsidiary to (i) within 12 months after the date Net Cash Proceeds
so received exceed 10% of Adjusted Consolidated Net Tangible Assets (A) apply
an amount equal to such excess Net Cash Proceeds to permanently repay
unsubordinated Indebtedness of the Company or any Restricted Subsidiary
providing a Subsidiary Guarantee pursuant to the "Limitation on Issuances of
Guarantees by Restricted Subsidiaries" covenant described above or
Indebtedness of any other Restricted Subsidiary, in each case owing to a
Person other than the Company or any of its Subsidiaries, or (B) invest an
amount equal to such excess Net Cash
 
                                      105
<PAGE>
 
Proceeds, or the amount of such Net Cash Proceeds not so applied pursuant to
clause (A) (or enter into a definitive agreement committing to so invest
within 12 months after the date of such agreement), in capital assets of a
nature or type or that are used in a business (or in a Person having capital
assets of a nature or type, or engaged in a business) similar or related to
the nature or type of the property and assets of, or the business of, the
Company and its Restricted Subsidiaries existing on the date of such
investment (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and evidenced by a Board Resolution) and
(ii) apply (no later than the end of the 12-month period referred to in clause
(i)) such excess Net Cash Proceeds (to the extent not applied pursuant to
clause (i)) as provided in the following paragraph of this "Limitation on
Asset Sales" covenant. The amount of such excess Net Cash Proceeds required to
be applied (or to be committed to be applied) during such 12-month period as
set forth in clause (i) of the preceding sentence and not applied as so
required by the end of such period shall constitute "Excess Proceeds."
 
  If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to
this "Limitation on Asset Sales" covenant totals at least $5 million, the
Company must commence, not later than the fifteenth Business Day of such
month, and consummate an Offer to Purchase from the Holders on a pro rata
basis an aggregate principal amount of Notes equal to the Excess Proceeds on
such date, at a purchase price equal to 100% of the principal amount of the
Notes plus, in each case, accrued interest to the Payment Date.
 
  Commission Reports and Reports to Holders
 
  The Company shall file with the Commission the annual, quarterly and other
reports and other information required by Section 13(a) or 15(d) of the
Exchange Act, regardless of whether such sections of the Exchange Act are
applicable to the Company (unless the Commission will not accept such a
filing). The Company shall mail or cause to be mailed copies of such reports
and information to Holders and the Trustee within 15 days after the date it
files such reports and information with the Commission or after the date it
would have been required to file such reports and information with the
Commission had it been subject to such sections of the Exchange Act; provided,
however, that the copies of such reports and information mailed to Holders may
omit exhibits, which the Company will supply to any Holder at such Holder's
request.
 
REPURCHASE OF EXCHANGE NOTES UPON A CHANGE OF CONTROL
 
  The Company shall commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Exchange Notes then
outstanding, at a purchase price equal to 101% of the principal amount
thereof, plus accrued interest to the Payment Date.
 
  There can be no assurance that the Company will have sufficient funds
available at the time of any Change of Control to make any debt payment
(including repurchases of Exchange Notes) required by the foregoing covenant
(as well as may be contained in other securities of the Company which might be
outstanding at the time). The foregoing covenant requiring the Company to
repurchase the Exchange Notes will, unless consents are obtained, require the
Company to repay all indebtedness then outstanding which by its terms would
prohibit such Exchange Note repurchase, either prior to or concurrently with
such Exchange Note repurchase.
 
EVENTS OF DEFAULT
 
  The following events are defined as "Events of Default" in the Indenture:
(a) defaults in the payment of principal of (or premium, if any, on) any Note
when the same becomes due and payable at maturity, upon acceleration,
redemption or otherwise; (b) defaults in the payment of interest on any Note
when the same becomes due and payable, which defaults continue for a period of
30 days; provided that a failure to make any of the first six scheduled
interest payments on the Notes on the applicable Interest Payment Date will
constitute an Event of Default with no grace or cure period; (c) defaults in
the performance or breach of the provisions of the Indenture applicable to
mergers, consolidations and transfers of all or substantially all of the
assets of the Company or mandatory redemption, or the failure to make or
consummate an Offer to Purchase in accordance
 
                                      106
<PAGE>
 
with the "Limitation on Asset Sales" or the "Repurchase of Notes upon a Change
of Control" covenant described above; (d) defaults in the performance or
breach of any covenant or agreement of the Company in the Indenture or under
the Notes (other than a default specified in clause (a), (b) or (c) above),
which default or breach continues for a period of 30 consecutive days after
written notice by the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes then outstanding; (e) there occurs with respect
to any issue or issues of Indebtedness of the Company or any Significant
Subsidiary having an outstanding principal amount of $5 million or more in the
aggregate for all such issues of all such Persons, whether such Indebtedness
now exists or shall hereafter be created, (I) an event of default that has
caused the holder thereof to declare such Indebtedness to be due and payable
prior to its Stated Maturity and such Indebtedness has not been discharged in
full or such acceleration has not been rescinded or annulled within 30 days of
such acceleration and/or (II) the failure to make a principal payment at the
final (but not any interim) fixed maturity and such defaulted payment shall
not have been made, waived or extended within 30 days of such payment default;
(f) any final judgment or order (not covered by insurance) for the payment of
money in excess of $5 million in the aggregate for all such final judgments or
orders against all such Persons (treating any deductibles, self-insurance or
retention as not so covered) shall be rendered against the Company or any
Significant Subsidiary and shall not be paid or discharged, and there shall be
any period of 30 consecutive days following entry of the final judgment or
order that causes the aggregate amount for all such final judgments or orders
outstanding and not paid or discharged against all such Persons to exceed $5
million during which a stay of enforcement of such final judgment or order, by
reason of a pending appeal or otherwise, shall not be in effect; (g) a court
having jurisdiction in the premises enters a decree or order for (A) relief in
respect of the Company or any Significant Subsidiary in an involuntary case
under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, (B) appointment of a receiver, liquidator, assignee,
custodian, trustee, sequestrator or similar official of the Company or any
Significant Subsidiary or for all or substantially all of the property and
assets of the Company or any Significant Subsidiary or (C) the winding up or
liquidation of the affairs of the Company or any Significant Subsidiary and,
in each case, such decree or order shall remain unstayed and in effect for a
period of 60 consecutive days; (h) the Company or any Significant Subsidiary
(A) commences a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consents to the entry of an
order for relief in an involuntary case under any such law, (B) consents to
the appointment of or taking possession by a receiver, liquidator, assignee,
custodian, trustee, sequestrator or similar official of the Company or any
Significant Subsidiary or for all or substantially all of the property and
assets of the Company or any Significant Subsidiary or (C) effects any general
assignment for the benefit of creditors; or (i) the Pledge Agreement shall
cease to be in full force and effect or enforceable in accordance with its
terms, other than in accordance with its terms.
 
  If an Event of Default (other than an Event of Default specified in clause
(g) or (h) above that occurs with respect to the Company) occurs and is
continuing under the Indenture, the Trustee or the Holders of at least 25% in
aggregate principal amount of the Notes then outstanding, by written notice to
the Company (and to the Trustee if such notice is given by the Holders), may,
and the Trustee at the request of such Holders shall, declare the principal
of, premium, if any, and accrued interest on the Notes to be immediately due
and payable. Upon a declaration of acceleration, such principal, premium, if
any, and accrued interest shall be immediately due and payable. In the event
of a declaration of acceleration because an Event of Default set forth in
clause (e) above has occurred and is continuing, such declaration of
acceleration shall be automatically rescinded and annulled if the event of
default triggering such Event of Default pursuant to clause (e) shall be
remedied or cured by the Company or the relevant Significant Subsidiary or
waived by the holders of the relevant Indebtedness within 60 days after the
declaration of acceleration with respect thereto. If an Event of Default
specified in clause (g) or (h) above occurs with respect to the Company, the
principal of, premium, if any, and accrued interest on the Notes then
outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder. The
Holders of at least a majority in principal amount of the outstanding Notes,
by written notice to the Company and to the Trustee, may waive all past
defaults and rescind and annul a declaration of acceleration and its
consequences if (i) all existing Events of Default, other than the nonpayment
of the principal of, premium, if any, and interest on the Notes that have
become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any
 
                                      107
<PAGE>
 
judgment or decree of a court of competent jurisdiction. For information as to
the waiver of defaults, see "--Modification and Waiver."
 
  The Holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith
may be unduly prejudicial to the rights of Holders of Notes not joining in the
giving of such direction and may take any other action it deems proper that is
not inconsistent with any such direction received from Holders of Notes. A
Holder may not pursue any remedy with respect to the Indenture or the Notes
unless: (i) the Holder gives the Trustee written notice of a continuing Event
of Default; (ii) the Holders of at least 25% in aggregate principal amount of
outstanding Notes make a written request to the Trustee to pursue the remedy;
(iii) such Holder or Holders offer the Trustee indemnity satisfactory to the
Trustee against any costs, liability or expense; (iv) the Trustee does not
comply with the request within 60 days after receipt of the request and the
offer of indemnity; and (v) during such 60-day period, the Holders of a
majority in aggregate principal amount of the outstanding Notes do not give
the Trustee a direction that is inconsistent with the request. However, such
limitations do not apply to the right of any Holder of a Note to receive
payment of the principal of, premium, if any, or interest on, such Note or to
bring suit for the enforcement of any such payment, on or after the due date
expressed in the Notes, which right shall not be impaired or affected without
the consent of the Holder.
 
  The Indenture requires certain officers of the Company to certify, on or
before a date not more than 90 days after the end of each fiscal year, that a
review has been conducted of the activities of the Company and its Restricted
Subsidiaries and the performance of the Company and its Restricted
Subsidiaries under the Indenture and that the Company has fulfilled all
obligations thereunder, or, if there has been a default in the fulfillment of
any such obligation, specifying each such default and the nature and status
thereof. The Company is also obligated to notify the Trustee of any default or
defaults in the performance of any covenants or agreements under the
Indenture.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Company shall not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its
property and assets (as an entirety or substantially an entirety in one
transaction or a series of related transactions) to, any Person or permit any
Person to merge with or into the Company unless: (i) the Company shall be the
continuing Person, or the Person (if other than the Company) formed by such
consolidation or into which the Company is merged or that acquired or leased
such property and assets of the Company shall be a corporation organized and
validly existing under the laws of the United States of America or any
jurisdiction thereof, and shall expressly assume, by a supplemental indenture,
executed and delivered to the Trustee, all of the obligations of the Company
on all of the Notes and under the Indenture; (ii) immediately after giving
effect to such transaction, no Default or Event of Default shall have occurred
and be continuing; (iii) immediately after giving effect to such transaction
on a pro forma basis, the Company or any Person becoming the successor obligor
of the Notes shall have a Consolidated Net Worth equal to or greater than the
Consolidated Net Worth of the Company immediately prior to such transaction;
(iv) immediately after giving effect to such transaction on a pro forma basis,
the Company, or any Person becoming the successor obligor of the Notes, as the
case may be, could Incur at least $1.00 of Indebtedness under the first
paragraph of the "Limitation on Indebtedness" covenant described above;
provided, however, that this clause (iv) shall not apply to a consolidation or
merger with or into (x) a Wholly Owned Restricted Subsidiary with a positive
net worth or (y) ITC Holding, provided that (A) in connection with any such
merger or consolidation, no consideration (except Capital Stock (other than
Redeemable Stock) in the surviving Person or the Company (or a Person that
owns directly or indirectly all of the Capital Stock of the surviving Person
or the Company immediately following such transaction)) shall be issued or
distributed to the stockholders of the Company and (B) in connection with a
consolidation or merger with or into ITC Holding, all Liens and Indebtedness
of ITC Holding and its Subsidiaries (other than the Company and its Restricted
Subsidiaries) outstanding immediately prior to such transaction would, if
Incurred at such time, have been permitted to be Incurred by the Company
 
                                      108
<PAGE>
 
and its Restricted Subsidiaries for all purposes of the Indenture; and (v) the
Company delivers to the Trustee an Officers' Certificate (attaching the
arithmetic computations to demonstrate compliance with clauses (iii) and
(iv) above) and an Opinion of Counsel, in each case stating that such
consolidation, merger or transfer and such supplemental indenture comply with
this provision and that all conditions precedent provided for herein relating
to such transaction have been complied with; provided, however, that clauses
(iii) and (iv) above do not apply if, in the good faith determination of the
Board of Directors of the Company, whose determination shall be evidenced by a
Board Resolution, the principal purpose of such transaction is to change the
state of incorporation of the Company; and provided further that any such
transaction shall not have as one of its purposes the evasion of the foregoing
limitations.
 
DEFEASANCE
 
  Defeasance and Discharge. The Indenture provides that the Company will be
deemed to have paid and will be discharged from any and all obligations in
respect of the Notes on the 123rd day after the deposit referred to below, and
the provisions of the Indenture will no longer be in effect with respect to
the Notes (except for, among other matters, certain obligations to register
the transfer or exchange of the Notes, to replace stolen, lost or mutilated
Notes, to maintain paying agencies and to hold monies for payment in trust)
if, among other things, (A) the Company has deposited with the Trustee, in
trust, money and/or U.S. Government Obligations that through the payment of
interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of, premium, if
any, and accrued interest on the Notes on the Stated Maturity of such payments
in accordance with the terms of the Indenture and the Notes, (B) the Company
has delivered to the Trustee (i) either (x) an Opinion of Counsel to the
effect that Holders will not recognize income, gain or loss for federal income
tax purposes as a result of the Company's exercise of its option under this
"Defeasance" provision and will be subject to federal income tax on the same
amount and in the same manner and at the same times as would have been the
case if such deposit, defeasance and discharge had not occurred, which Opinion
of Counsel must be based upon (and accompanied by a copy of) a ruling of the
Internal Revenue Service to the same effect unless there has been a change in
applicable federal income tax law after the Closing Date such that a ruling is
no longer required or (y) a ruling directed to the Trustee received from the
Internal Revenue Service to the same effect as the aforementioned Opinion of
Counsel and (ii) an Opinion of Counsel to the effect that the creation of the
defeasance trust does not violate the Investment Company Act of 1940 and after
the passage of 123 days following the deposit, the trust fund will not be
subject to the effect of Section 547 of the United States Bankruptcy Code or
Section 15 of the New York Debtor and Creditor Law, (C) immediately after
giving effect to such deposit on a pro forma basis, no Event of Default, or
event that after the giving of notice or lapse of time or both would become an
Event of Default, shall have occurred and be continuing on the date of such
deposit or during the period ending on the 123rd day after the date of such
deposit, and such deposit shall not result in a breach or violation of, or
constitute a default under, any other agreement or instrument to which the
Company or any of its Subsidiaries is a party or by which the Company or any
of its Subsidiaries is bound, and (D) if at such time the Notes are listed on
a national securities exchange, the Company has delivered to the Trustee an
Opinion of Counsel to the effect that the Notes will not be delisted as a
result of such deposit, defeasance and discharge.
 
  Defeasance of Certain Covenants and Certain Events of Default. The Indenture
further provides that the provisions of the Indenture will no longer be in
effect with respect to clauses (iii) and (iv) under "Consolidation, Merger and
Sale of Assets" and all the covenants described herein under "Covenants,"
clause (d) under "Events of Default" with respect to such covenants and
clauses (iii) and (iv) under "Consolidation, Merger and Sale of Assets," and
that clauses (e) and (f) under "Events of Default" shall be deemed not to be
Events of Default, upon, among other things, the deposit with the Trustee, in
trust, of money and/or U.S. Government Obligations that through the payment of
interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of, premium, if
any, and accrued interest on the Notes on the Stated Maturity of such payments
in accordance with the terms of the Indenture and the Notes, the satisfaction
of the provisions described in clauses (B)(ii), (C) and (D) of the preceding
paragraph and the delivery by the Company to the Trustee of an Opinion of
Counsel to the effect that, among other things, the Holders will
 
                                      109
<PAGE>
 
not recognize income, gain or loss for federal income tax purposes as a result
of such deposit and defeasance of certain covenants and Events of Default and
will be subject to federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit and
defeasance had not occurred.
 
  Defeasance and Certain Other Events of Default. In the event the Company
exercises its option to omit compliance with certain covenants and provisions
of the Indenture with respect to the Notes as described in the immediately
preceding paragraph and the Notes are declared due and payable because of the
occurrence of an Event of Default that remains applicable, the amount of money
and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Notes at the time of their Stated
Maturity but may not be sufficient to pay amounts due on the Notes at the time
of the acceleration resulting from such Event of Default. However, the Company
will remain liable for such payments.
 
MODIFICATION AND WAIVER
 
  Modifications and amendments of the Indenture may be made by the Company and
the Trustee with the consent of the Holders of not less than a majority in
aggregate principal amount of the outstanding Notes; provided, however, that
no such modification or amendment may, without the consent of each Holder
affected thereby, (i) change the Stated Maturity of the principal of, or any
installment of interest on, any Note, (ii) reduce the principal of, or
premium, if any, or interest on, any Note, (iii) change the place or currency
of payment of principal of, or premium, if any, or interest on, any Note, (iv)
impair the right to institute suit for the enforcement of any payment on or
after the Stated Maturity (or, in the case of a redemption, on or after the
Redemption Date) of any Note, (v) reduce the above-stated percentage of
outstanding Notes the consent of whose Holders is necessary to modify or amend
the Indenture, (vi) waive a default in the payment of principal of, premium,
if any, or interest on the Notes or (vii) reduce the percentage or aggregate
principal amount of outstanding Notes the consent of whose Holders is
necessary for waiver of compliance with certain provisions of the Indenture or
for waiver of certain defaults.
 
BOOK-ENTRY; DELIVERY AND FORM
   
  The certificates representing the Exchange Notes will initially be
represented by one or more permanent global Notes in definitive, fully
registered form without interest coupons (each a "Global Note") and will be
deposited with the Trustee as custodian for, and registered in the name of, a
nominee of DTC. Except in the limited circumstances described below under
"Certificated Notes," owners of beneficial interests in a Global Note will not
be entitled to receive physical delivery of Certificated Notes (as defined
below).     
   
  Ownership of beneficial interests in a Global Note will be limited to
persons who have accounts with DTC ("participants") or persons who hold
interests through participants. Ownership of beneficial interests in a Global
Note will be shown on, and the transfer of that ownership will be effected
only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants).     
   
  So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Exchange Notes represented by such Global Note for
all purposes under the Indenture and the Exchange Notes. No beneficial owner
of an interest in a Global Note will be able to transfer that interest except
in accordance with DTC's applicable procedures, in addition to those provided
for under the Indenture.     
   
  Payments of the principal of, and interest on, a Global Note will be made to
DTC or its nominee, as the case may be, as the registered owner thereof.
Neither the Company, the Trustee nor any Paying Agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.     
   
  The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Note, will credit participants'
accounts with payments in amounts proportionate to their     
 
                                      110
<PAGE>
 
   
respective beneficial interests in the principal amount of such Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in such Global Note
held through such participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts
of customers registered in the names of nominees for such customers. Such
payments will be the responsibility of such participants.     
   
  Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds.     
   
  The Company expects that DTC will take any action permitted to be taken by a
holder of Exchange Notes (including the presentation of Exchange Notes for
exchange as described below) only at the direction of one or more participants
to whose account the DTC interests in a Global Note is credited and only in
respect of such portion of the aggregate principal amount of Exchange Notes as
to which such participant or participants has or have given such direction.
However, if there is an Event of Default under the Exchange Notes, DTC will
exchange the applicable Global Note for Certificated Exchange Notes, which it
will distribute to its participants.     
   
  The Company understands that: DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a clearing corporation within the meaning of the New York Uniform
Commercial Code and a "clearing agency" registered pursuant to the provisions
of Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical
movement of certificates and certain other organizations. Indirect access to
the DTC system is available to others such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").     
   
  Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in a Global Note among participants of DTC,
it is under no obligation to perform or continue to perform such procedures,
and such procedures may be discontinued at any time. Neither the Company nor
the Trustee will have any responsibility for the performance by DTC or its
respective participants or indirect participants of their respective
obligation under the rules and procedures governing their operations.     
   
CERTIFICATED NOTES     
   
  If DTC is at any time unwilling or unable to continue as a depositary for
the Global Notes, and a successor depositary is not appointed by the Company
within 90 days, the Company will issue Certificated Notes in exchange for the
Global Note. Holders of an interest in a Global Note may receive a
Certificated Note in accordance with DTC's rules and procedures in addition to
those provided for under the Indenture.     
       
       
NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS OR
EMPLOYEES
 
  The Indenture provides that no recourse for the payment of the principal of,
premium, if any, or interest on any of the Exchange Notes or for any claim
based thereon or otherwise in respect thereof, and no recourse under or upon
any obligation, covenant or agreement of the Company in the Indenture, or in
any of the Exchange Notes or because of the creation of any Indebtedness
represented thereby, shall be had against any incorporator, stockholder,
officer, director, employee or controlling person of the Company or of any
successor Person thereof. Each Holder, by accepting the Exchange Notes, waives
and releases all such liability.
 
CONCERNING THE TRUSTEE
 
  The Indenture provides that, except during the continuance of a Default, the
Trustee will not be liable, except for the performance of such duties as are
specifically set forth in such Indenture. If an Event of Default has occurred
and is continuing, the Trustee will use the same degree of care and skill in
its exercise as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.

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

                             PLAN OF DISTRIBUTION
 
  Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. This Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Notes received in exchange for Senior
Notes where such Senior Notes were acquired as a result of market-making
activities or other trading activities. The Company has agreed that, for a
period not to exceed 180 days after the Expiration Date, it will furnish
additional copies of this Prospectus, as amended or supplemented, to any
broker-dealer that reasonably requests such documents for use in connection
with any such resale.
 
  The Company will not receive any proceeds from any sale of Exchange Notes by
broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or negotiated prices. Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from
any such broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit of any
such resale of Exchange Notes and any commissions or concessions received by
any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
 
  The Exchange Notes will constitute a new issue of securities with no
established trading market. The Company does not intend to list the Exchange
Notes on any national securities exchange or to seek approval for quotation
through any automated quotation system. The Company has been advised by the
Placement Agents that following completion of the Exchange Offer, the
Placement Agents intend to make a market in the Exchange Notes. However, the
Placement Agents are not obligated to do so and any market-making activities
with respect to the Exchange Notes may be discontinued at any time without
notice. Accordingly, no assurance can be given that an active public or other
market will develop for the Exchange Notes or as to the liquidity of or the
trading market for the Exchange Notes. If a trading market does not develop or
is not maintained, holders of the Exchange Notes may experience difficulty in
reselling the Exchange Notes or may be unable to sell them at all. If a market
for the Exchange Notes develops, any such market may cease at any time. If a
public trading market develops for the Exchange Notes, future trading prices
of the Exchange Notes will depend on many factors, including, among other
things, prevailing interest rates, the market for similar securities, the
financial conditions and results of operations of the Company and other
factors beyond the control of the Company, including general economic
conditions. Notwithstanding the registration of the Exchange Notes in the
Exchange Offer, holders who are "affiliates" of the Company (within the
meaning of Rule 405 under the Securities Act) may publicly offer for sale or
resell the Exchange Notes only in compliance with the provisions of Rule 144
under the Securities Act or any other available exemptions under the
Securities Act.
 
  The Company has agreed to pay all expenses incident to the Exchange Offer
other than commissions or concessions of any brokers or dealers, and will
indemnify the holders of the Senior Notes (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act.

a competitor carrier places its network connection equipment inside the local
exchange company's central offices. Virtual co-location is an alternative to
physical co-location pursuant to which the local exchange company permits a
competitor carrier to connect its network to the local exchange company's
central offices on comparable terms, even through the competitor carrier's
network connection equipment is not physically located inside the central
offices.
 
  Dedicated--Local telecommunications lines reserved for use by particular

facility with one or more network nodes. Traffic is routed between the hub and
each of the nodes simultaneously in both a clockwise and a counterclockwise
direction. In the event of a cable cut or component failure along one of these
paths, traffic will continue to flow along the alternate path so no traffic is
lost. In the event of a catastrophic node failure, other nodes will be

To ITC/\DeltaCom, Inc.:
   
  We have audited the accompanying balance sheet of ITC/\DELTACOM, INC. (a
Delaware corporation) as of June 30, 1997 and the related statements of
operations, stockholder's deficit and cash flows for the period from inception
(March 24, 1997) to June 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these statements based on our audit.     
   
  We conducted our audit in accordance with generally accepted auditing
standards. 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 audit provides a reasonable basis
for our opinion.     
   
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of ITC/\DeltaCom, Inc. as of
June 30, 1997 and the results of its operations and its cash flows for the
period from inception (March 24, 1997) through June 30, 1997 in conformity
with generally accepted accounting principles.

                              JUNE 30, 1997     
 
1. ORGANIZATION AND NATURE OF BUSINESS
   
  ITC/\DeltaCom, Inc. (the "Company") was incorporated under the laws of the
state of Delaware on March 24, 1997. The purpose of incorporating the Company
was to enable ITC Holding Company, Inc. ("ITC Holding"), the Company's parent
company and only stockholder to complete a reorganization of certain of its
wholly owned subsidiaries on July 25, 1997 as follows:     
     
  .  Eastern Telecom, Inc. (d.b.a. InterQuest) and ITC Transmission Systems
     II, Inc. were merged with and into Interstate FiberNet, Inc. (formerly
     ITC Transmission Systems, Inc.) ("FiberNet").     
     
  .  ITC Holding contributed all of the outstanding capital stock of
     FiberNet, DeltaCom, Inc. ("DeltaCom") and Gulf States Transmission
     Systems, Inc. to the Company.     
     
  .  The Company contributed all of the outstanding capital stock of
     DeltaCom, Inc. and Gulf States Transmission Systems, Inc. to FiberNet.
            
  In connection with the Reorganization, FiberNet undertook to repay (and
DeltaCom agreed to reimburse FiberNet) approximately $31 million of DeltaCom's
advances from ITC Holding. ITC Holding then forgave such indebtedness and
contributed it to FiberNet as additional equity.     
          
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES     
   
 Cash and cash equivalents     
   
  For purposes of the statement of cash flows, the Company considers all
investments purchased with a maturity of three months or less to be cash
equivalents.     
   
 Debt issuance costs     
   
  The Company has incurred debt issuance costs in connection with its long-
term debt. These costs have been capitalized and are being amortized over the
term of the related debt.     
   
3. EQUITY INTERESTS     
 
CAPITAL STOCK
   
  The Company has authorized two classes of common stock. Holders of the
Company's Class A Common Stock have one vote per share, while holders of the
Company's Class B Common Stock have ten votes per share. At June 30, 1997, 0
shares of the Company's Class A Common Stock and 15,000,000 shares of the
Company's Class B Common Stock were outstanding.     
 
EMPLOYEE STOCK OPTION PLAN
 
  On March 24, 1997, the Company adopted and its stockholder approved the 1997
Stock Option Plan (the "Stock Option Plan"). The Stock Option Plan provides
for the grant of options that are intended to qualify as "incentive stock
options" under Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code") to employees of the Company, its subsidiaries to be obtained in
the reorganization described in Note 1, 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 1.5 million shares of
Class A Common Stock pursuant to options granted under the Stock Option Plan
(subject to anti-dilution adjustments in the event of a stock split,
recapitalization or similar transaction). The maximum number of shares subject
to options that can be awarded under the Stock Option

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
Plan to any person is 500,000 shares. The Compensation Committee of the Board
of Directors will administer the Stock Option Plan and will grant options to
purchase Class A 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
Class A 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 Class A 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 Class A 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 Class A Common Stock). There is also a $100,000 limit
on the value of Class A 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 Board of Directors may amend or terminate the Stock Option Plan with
respect to shares of Class A Common Stock as to which options have not been
granted.
   
  On March 24, 1997, the Company granted options to purchase 789,000 shares of
Class A 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 ($7.20) as determined by the Company's stockholder's board of
directors based on equity transactions and other analyses. On July 29, 1997,
the Company granted options to purchase 105,254 shares of Class A 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
($7.20) as determined by the Company's stockholder's board of directors based
on equity transactions and other analyses.     
 
DIRECTORS STOCK OPTION PLAN
 
  On March 24, 1997, the Company adopted and its stockholder approved the
Directors Stock Option Plan (the "Directors Plan"). The Directors 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, ITC Holding, or any
subsidiary of the Company (each an "Eligible Director"). The Directors Plan
authorizes the issuance of up to 150,000 shares of Class A Common Stock
pursuant to options granted under the Directors Plan (subject to anti-dilution
adjustments in the event of a stock split, recapitalization or similar
transaction). The option exercise price for options granted under the
Directors Plan will be 100% of the fair market value of the shares of Class A
Common Stock on the date of grant of the option. Under the Directors Plan,
each Eligible Director will be granted an option to purchase 10,000 shares of
Class A 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 10,000 shares of
the Company's Class A common stock to each of its six nonemployee directors.
All options were granted at a price equal to the estimated fair value of the
common stock on the date of grant ($7.20) as determined by the Company's
stockholder's board of directors based on equity transactions and other
analyses.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
   
STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123     
   
  During 1995, the Financial Accounting Standards Board issued SFAS No. 123,
"Accounting for Stock-Based Compensation," which defines a fair value-based
method of accounting for an employee stock option or similar equity instrument
and encourages all entities to adopt that method of accounting for all of
their employee stock compensation plans. However, it also allows an entity to
continue to measure compensation cost for those plans using the method of
accounting prescribed by Accounting Principles Board ("APB") Opinion No. 25,
"Accounting for Stock Issued to Employees." The Company has elected to account
for options granted to employees under APB Opinion No. 25, under which no
compensation cost has been recognized. Options granted to non-employees, if
any, will be accounted for under SFAS No. 123 and compensation expense equal
to the fair value of the options granted will be recognized.     
   
4. FINANCING ARRANGEMENTS     
   
  FiberNet has entered into a commitment letter with a third-party lender to
provide a five-year term and revolving credit facility of up to $100 million
to be used for working capital and other purposes, including capital
expenditures and permitted acquisitions. The credit facility will include a
$50 million multi-draw term facility and a $50 million revolving credit
facility. The commitment letter contemplates that obligations under the credit
facility will be guaranteed by the Company. The credit facility is expected to
contain a number of covenants applicable to FiberNet and its subsidiaries
obtained in the reorganization described in Note 1 and to the Company,
including, among others, covenants limiting debt to be incurred, dividends to
be paid, as well as other equity distributions and stock repurchases and
covenants requiring compliance with certain financial ratios.     
   
  On June 3, 1997, the Company completed the issuance of $200 million
principal amount of 11% Senior Notes due 2007 (the "Offering"). Proceeds from
the Offering were held by the trustee until all regulatory approvals related
to the reorganization described in Note 1 were received. On July 25, 1997, the
reorganization was completed and the proceeds from the Offering were released
to the Company. In accordance with the Indenture related to the Notes,
approximately $62.7 million of the approximately $192.7 million net proceeds
was invested in U.S. government securities, which are in a pledged account
held by the Trustee to secure and fund the first six interest payments on the
Notes. Additionally, approximately $99.6 million of the net proceeds was used
to repay outstanding debt and related accrued interest owed by the Company's
subsidiaries. The Company intends to use the remaining approximately $30.4
million of net proceeds (i) to fund market expansion activities of the
Company's telecommunications business, including development and construction
costs of the Company's fiber optic network and its regional sales offices, and
(ii) for additional working capital and other general corporate purposes,
including the funding of cash flow deficits (after capital expenditures).
Pending such uses, the Company has invested such amounts in U.S. government
securities.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
   
To Interstate FiberNet, Inc. (formerly ITC Transmission Systems, Inc.),     
ITC Transmission Systems II, Inc.,
Gulf States Transmission Systems, Inc.,
Eastern Telecom, Inc., d.b.a. InterQuest, and
DeltaCom, Inc.:
   
  We have audited the accompanying combined balance sheets of INTERSTATE
FIBERNET, INC., (FORMERLY ITC TRANSMISSION SYSTEMS, INC.) (a Delaware
corporation), ITC TRANSMISSION SYSTEMS II, INC. (a Delaware corporation), GULF
STATES TRANSMISSION SYSTEMS, INC. (a Delaware corporation), EASTERN TELECOM,
INC., D.B.A. INTERQUEST (a Georgia corporation), AND DELTACOM, INC. (an
Alabama corporation) (collectively referred to as the "Companies" and
contributed to ITC/\DeltaCom, Inc. in connection with the reorganization as
discussed in Notes 1 and 16) as of December 31, 1995 and 1996 and the related
combined statements of operations, stockholder's equity, and cash flows for
each of the three years in the period ended December 31, 1996. These combined
financial statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these combined financial statements
based on our audits.     
 
  We conducted our audits in accordance with generally accepted auditing
standards. 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 combined financial statements referred to above present
fairly, in all material respects, the combined financial position of the
Companies as of December 31, 1995 and 1996 and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1996 in conformity with generally accepted accounting principles.

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
DeltaCom, Inc. ("DeltaCom"), are all wholly owned subsidiaries of ITC Holding
Company, Inc. (the "Parent"). ITC/\DeltaCom, Inc. ("ITC/\DeltaCom") was
incorporated on March 24, 1997 under the laws of the State of Delaware, as a
wholly owned subsidiary of the Parent, to acquire and operate the Fiber
Companies and DeltaCom. Upon receipt of certain regulatory approvals and
certain other consents, on July 25, 1997 the Parent completed the
reorganization of such subsidiaries (the "Reorganization"), as follows:     
       
    a. InterQuest and Transmission II were merged with and into FiberNet.
              
    b. The Parent contributed all of the issued and outstanding capital
       stock of FiberNet, DeltaCom and GSTS to ITC/\DeltaCom Inc.     
       
    c. ITC/\DeltaCom contributed all of the outstanding capital stock of
       DeltaCom and GSTS to FiberNet.     
   
  As a result of the Reorganization, ITC/\DeltaCom became the sole stockholder
of FiberNet and FiberNet became the sole stockholder of both GSTS and
DeltaCom. ITC/\DeltaCom, FiberNet, Transmission II, GSTS, InterQuest, and
DeltaCom are collectively referred to herein as the "Companies."     
   
  At December 31, 1996, FiberNet and Transmission II together held 100% of the
ownership interests in Interstate FiberNet ("Interstate"), a Georgia general
partnership (Note 5). Effective with the Reorganization, Interstate was
absorbed by law into FiberNet. GSTS held a 36% ownership in and is the
managing partner of Gulf States FiberNet ("Gulf States"), a Georgia general
partnership (Note 5). Subsequent to year-end, the Parent agreed to purchase
the remaining 64% interest in Gulf States (Note 16).     
 
 Basis of Accounting and Financial Statement Presentation
   
  The accompanying combined financial statements of the Companies are prepared
on the accrual basis of accounting and present their combined assets,
liabilities, revenues, expenses, and cash flows as if they existed as a
separate corporation during the periods presented. ITC/\DeltaCom's results of
operations, changes in stockholder's equity, and cash flow have been included
in the combined statements for the period from inception (March 24, 1997)
through June 30, 1997.     
 
  The financial information included herein may not necessarily reflect the
financial position, results of operations, or cash flows of the Companies in
the future or what the financial position, results of operations or cash flows
of the Companies would have been if they were combined as a separate stand
alone company during the periods presented.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
   
  The combined balance sheet as of June 30, 1997 and the combined statements
of operations and cash flows for the six months ended June 30, 1996 and 1997
are unaudited and have been prepared by management of the Companies in
accordance with the rules and regulations of the Securities and Exchange
Commission. In the opinion of management, the statements contain all
adjustments (consisting of only normal recurring items) necessary for the fair
presentation of the financial position and results of operations for the
interim period. The results of operations for the six months ended June 30,
1997 are not necessarily indicative of the results to be expected for the
entire year.     
 
  Investments in affiliated entities in which the Companies have at least 20%
ownership and do not have management control are accounted for using the
equity method. All material intercompany accounts and transactions have been
eliminated in the accompanying combined financial statements.
   
  Interstate was initially formed in 1992 as a partnership between FiberNet,
which held a 49% ownership interest, and SCANA Communications, Inc. ("SCANA"),
which held the remaining 51% interest. FiberNet accounted for this investment
using the equity method. On August 17, 1994, the Parent formed Transmission II
and purchased SCANA's 51% interest in Interstate (Note 5). To reflect this
step acquisition, the revenues and expenses of Interstate have been included
in the accompanying statements of operations for the full year ended December
31, 1994, with the preacquisition earnings attributable to SCANA prior to
August 17, 1994 deducted to determine combined net income of the Companies.
    
  On January 29, 1996, the Parent acquired 100% of the common stock of
DeltaCom (Note 13). The acquisition was accounted for using the purchase
method of accounting. The results of operations of DeltaCom have been included
in the accompanying statements of operations since the date of acquisition.
   
  Gulf States was initially formed in 1994 as a partnership between GSTS,
which held a 36% ownership interest, and SCANA, which held the remaining 64%
interest. GSTS accounted for this investment using the equity method. On March
27, 1997, GSTS purchased SCANA's 64% interest in Gulf States (Note 16). To
reflect this step acquisition, the revenues and expenses of Gulf States have
been included in the statement of operations for the six months ended June 30,
1997, with the preacquisition losses attributable to SCANA prior to March 27,
1997 deducted to determine the combined net loss of the Companies.     
 
 Nature of Business
 
  The Companies operate primarily in two business segments. DeltaCom is a
regional long-distance company operating primarily in the State of Alabama.
DeltaCom is engaged in the retail sale of long-distance services such as
traditional switched and dedicated long distance; 800/888 calling; calling
card and operator services; ATM and frame relay; high-capacity broadband
private line services, as well as Intranet, Internet, and Web page hosting and
development services; and customer premises equipment installation and repair.
DeltaCom primarily serves midsized 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 Fiber Companies have been providing Carriers' Carrier Services
since 1992 through their ownership interests in Interstate and, later, Gulf
States (Note 5).
 
  Certain of the Companies have experienced operating losses as a result of
efforts to build their network infrastructure and internal staffing, develop
their systems, and expand into new markets. Assuming financing is available,
all of the Companies expect to continue to focus on increasing their customer
base and expanding their network operations. Accordingly, the Companies expect
that their cost of services, selling, operations, and administration expenses
and capital expenditures will continue to increase significantly, all of which
will have a

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
negative impact on short-term operating results. In addition, the Companies
may change their pricing policies to respond to a changing competitive
environment. The Companies have entered into a commitment letter with a third-
party lender for a five-year, $100 million secured credit facility and
ITC/\DeltaCom has issued senior notes (Note 16) to refinance certain existing
indebtedness of the Companies and to provide additional funds for the
Companies' expansion plans. In the opinion of management, the Companies' cash
flows from operations and existing credit position, combined with management's
ability to scale back expansion plans if necessary, will be sufficient to meet
the capital and operating needs of the Companies through at least 1997.
However, there can be no assurance that growth in the Companies' revenue or
customer base will continue or that the Companies will be able to achieve or
sustain profitability and/or positive cash flow.
 
 Sources of Supplies
 
  The Companies voluntarily use a single vendor for transmission equipment
used in the Companies' network. However, if this vendor were unable to meet
the Companies' 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 Companies' accounts receivable potentially subject the Companies to
credit risk, as collateral is generally not required. The Companies' risk of
loss is limited due to advance billings to certain customers for services and
the ability to terminate access on delinquent accounts. The concentration of
credit risk is mitigated by the large number of customers comprising the
customer base. In 1996 and 1994, no customer represented more than 10% of the
Companies' combined operating revenues. However, in 1995, one customer
represented approximately 30% of the Companies' combined operating revenues.
 
 Regulation
 
  The Companies are subject to certain regulations and requirements of the
Federal Communications Commission and various state public service
commissions.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Accounting Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles 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 Companies consider all short term highly liquid investments with an
original maturity date of three months or less to be cash equivalents.
 
 Inventory
 
  Inventory is held only by DeltaCom and consists primarily of customer
premise equipment held for resale.
 
  Inventory is valued at the lower of cost or market, with cost determined
using the first in, first out method.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 Property and Equipment
 
  Property and equipment are recorded at cost or fair market value at the
acquisition date (Note 3). Depreciation of property and equipment is provided
using the composite or straight line method over the following estimated
useful lives:

</TABLE>
 
 Intangible Assets
 
  Intangible assets include the excess of the purchase price of acquisitions
over the fair value of net assets acquired, as well as various other acquired
intangibles. Intangible assets are amortized over the following estimated
useful lives:
 
<TABLE>
<CAPTION>
                                                                          YEARS

   <S>                                                                   <C>
   Goodwill.............................................................      40
   Trademark............................................................      40
   Customer base........................................................ 5 to 12
   Noncompete agreements................................................       5
</TABLE>
   
  At June 30, 1997, intangible assets also include debt issuance costs
associated with ITC/\DeltaCom's offering of Senior Notes (Note 16) as well as
the Bridge Facility (Note 16), which will be amortized over the life of the
related debt.     
 
 Long-Lived Assets
 
  The Companies adopted Statement of Financial Accounting Standards ("SFAS")
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-
Lived Assets to Be Disposed Of," on January 1, 1996. SFAS No. 121 establishes
accounting standards for the impairment of long lived assets and goodwill
related to those assets to be held and used and for long-lived assets and
certain identifiable intangible assets to be disposed of. The effect of
adopting SFAS No. 121 was not material to the Companies' combined financial
statements.
 
  The Companies review their 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 an impairment has occurred. An impairment is recognized when the
discounted future cash flows estimated to be generated by the acquired
business are sufficient to recover the current unamortized balance of the
intangible asset with the amount of any such deficiency charged to income in
the current year. Estimates of future cash flows are based on many factors,
including current operating results, expected market trends, and competitive
influences.
 
 Unearned Revenue
 
  Unearned revenue represents the liability for advanced billings to customers
for use of the Companies' fiber- optic network. Customers are billed in
advance for fixed monthly charges.
 
 Unbilled Revenue
 
  DeltaCom records unbilled revenue for long-distance services provided to
customers but not yet billed. Approximately $3.4 million in unbilled revenue
is included in accounts receivable in the accompanying balance sheet at
December 31, 1996.

<PAGE>
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 Income Taxes
 
  The Companies utilize 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.     
 
  The Companies are included in the consolidated federal income tax return of
the Parent. Under a tax-sharing arrangement, the Companies are 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 Companies were to have
filed on a separate return basis.
 
 Revenue Recognition
 
  Revenues are recognized as services are provided and consist primarily of
charges for use of long-distance services and for use of the Companies' fiber-
optic network.
 
 Fair Value of Financial Instruments
 
  The carrying values of the Companies' financial instruments, other than the
portion of their advance from the Parent related to the DeltaCom acquisition,
approximate their fair values. See Note 7 for the terms of the advance from
the Parent and the related interest swap agreements under which DeltaCom would
receive $285,308 if the agreements were terminated at December 31, 1996.
 
 Advertising Costs
 
  The Companies expense all advertising costs as incurred.

  At December 31, 1995, all goodwill related to the acquisition of Interstate
in 1994 (Note 5). See Notes 14 and 15 for a discussion of additional
intangible assets recorded in 1996 related to the acquisitions of DeltaCom and
the assets of Viper Computer Systems, Inc. ("ViperNet").
 
5. INVESTMENTS
 
 Gulf States
 
  At December 31, 1995 and 1996, investments represent GSTS's 36% ownership
interest in Gulf States, which was formed as a partnership between GSTS and
SCANA in 1994. Gulf States provides digital communications transport services
to communications common carriers in the states of Georgia, Texas, Alabama,
Mississippi, and Louisiana. GSTS is the managing partner and is responsible
for managing and operating Gulf States. Subsequent to year-end, the Parent
agreed to purchase the remaining 64% interest in Gulf States previously owned
by SCANA (Note 16). The following table summarizes various financial data of
Gulf States for the period from inception (August 17, 1994) to December 31,
1994 and for the years ended December 31, 1995 and 1996:

</TABLE>
 
 Interstate
   
  FiberNet owned a 49% interest in Interstate. On August 17, 1994, the Parent
exchanged 250,000 shares of its common stock, valued at $4,435,000, for
SCANA's 51% interest in Interstate and paid $132,417 in related expenses.
Simultaneously, the Parent formed Transmission II, transferred the 51%
ownership interest in Interstate to Transmission II, and made an equity
contribution to Transmission II equal to the value of the net assets acquired.
Goodwill of $1,780,566 related to this transaction has been "pushed down" to
the accounts of Transmission II. The goodwill represents the excess of the
purchase price paid for the 51% ownership interest in Interstate over the fair
market value of the net assets acquired.

  To reflect this step acquisition, the revenues and expenses of Interstate
for the year ended December 31, 1994 have been included in the accompanying
statements of operations, with the preacquisition earnings attributable to
SCANA deducted to determine combined net income of the Companies. In addition,
the statement of cash flows for the year ended December 31, 1994 reflects all
cash flows of Interstate during the year. The statement of stockholder's
equity reflects the step acquisition as a capital contribution to FiberNet
during 1994.     
   
  As discussed in Note 1, effective with the Reorganization, the partners of
Interstate merged and the partnership was absorbed by law into FiberNet.

 DeltaCom Advance From Parent Related to Acquisition
 
  As discussed in Note 12, the Parent funded the acquisition of DeltaCom and
the related refinancing of DeltaCom's outstanding debt through borrowings of
$74,005,598 on its own credit facility (the "Parent Credit Facility") with
First Union National Bank of North Carolina ("First Union") and CoBank, ACB
("CoBank"). These borrowings have been pushed down to the accounts of the
Company through the advance from Parent account under terms substantially
identical to those of the Parent Credit Facility.
 
  The Parent Credit Facility is a two year line of credit providing for
borrowings of up to $127.5 million on a two year revolving basis. The
available credit was initially split equally between CoBank ("Tranche A") and
First Union ("Tranche B"); however, First Union subsequently syndicated
Tranche B to several other lenders. On January 19, 1998, the Parent may elect
to convert all outstanding balances to a five year term loan with quarterly
principal payments through December 31, 2002. Loans made under the Parent
Credit Facility may, at any time or from time to time, be repaid in whole or
in part, upon certain notices to the administrative agent. As of December 31,
1996, the Parent had $86 million outstanding under this agreement.

<PAGE>
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Interest on the Parent Credit Facility is calculated on a 360 day year, at
the option of the Parent, as follows:
 
  . Tranche A--"Margin" plus either (a) prime, (b) 1-, 2-, 3-, or 6-month
    LIBOR, or (c) one year Treasury
 
  . Tranche B--"Margin" plus either (a) prime or (b) 1-, 2-, 3-, or 6-month
    LIBOR
 
  The applicable "Margin" varies based on the Parent's leverage ratio and is
adjusted quarterly. At December 31, 1996, the interest rate for both tranches
was calculated based on the applicable margin (2.25%) plus the 3 month LIBOR
rate (5.53125%).
   
  The Parent has also entered into a forward starting interest rate swap
agreement with First Union to hedge its interest rate exposure under the
Parent Credit Facility. The agreement swaps notional amounts of $50 million
and $41 million under the Parent Credit Facility with fixed rates of 8.66% and
8.53%, respectively. As of December 31, 1996, DeltaCom's proportionate share
of the fee the Parent would receive upon termination of the swap agreement was
$285,308. Upon the Reorganization (Note 16), DeltaCom will repay its portion
of these borrowings at an interest rate of 8.595%, which approximates the
Parent's average interest rate under these interest rate swap agreements. At
December 31, 1996, the balance sheet reflects approximately $5.8 million of
accrued interest related to DeltaCom's advance from Parent.     
   
  The Parent Credit Facility includes certain financial covenants and ratios.
At December 31, 1996, the Parent was in compliance with these requirements.
The Parent Credit Facility is jointly and severally guaranteed by the Parent,
the Companies, and other wholly owned or majority owned subsidiaries of the
Parent. The Parent Credit Facility is also secured by substantially all of the
assets of the Parent and the Companies, as well as the assets of other wholly
owned or majority owned subsidiaries of the Parent.     
       
 Cash Advance to Parent From DeltaCom
 
  Amounts reflected as cash advance to Parent from DeltaCom represent excess
funds from operations which are loaned to the Parent at an annual interest
rate of 8.25%. DeltaCom recorded interest income of $77,868 during 1996. The
advance is repayable on demand.
 
 Cash Advance From Parent to InterQuest
 
  Amounts reflected as cash advance from Parent to InterQuest represent
borrowings for operating purposes. Interest is payable at a rate equal to the
interest rate on the Parent Credit Facility plus .5%. InterQuest recorded
interest expense of $122,696 and $96,665 in 1995 and 1996, respectively.

  The Companies are included in the Parent's consolidated federal income tax
return. Prior to January 29, 1996, DeltaCom filed a separate federal income
tax return. The Companies each file separate state income tax returns.
 
  Under a tax-sharing arrangement, the Companies receive payment for net
operating losses generated for federal income tax purposes and used by the
Parent in the Parent's consolidated income tax return. Amounts receivable from
the Parent under this tax-sharing agreement are $523,782 and $2,546,534 at
December 31, 1995 and 1996, respectively. Additionally, certain of the
Companies have generated net operating losses for state income tax purposes.
At December 31, 1995 and 1996, $77,526 and $130,912 respectively, have been
included in current assets in the Companies' balance sheets. Loss
carryforwards of approximately $11,000, $67,000, and $53,000 will expire in
2009, 2010, and 2011, respectively. In management's opinion, the Companies
will generate operating income sufficient to utilize all of the remaining
state net operating loss carryforwards in 1997.

  ITC/\DeltaCom has two classes of common stock authorized. Holders of
ITC/\DeltaCom's Class A Common Stock have one vote per share, while holders of
Class B Common Stock have ten votes per share. Upon the formation of
ITC/\DeltaCom (Note 1), 15,000,000 shares of Class B Common Stock were
outstanding.     
 
 Parent Stock Option Plan
 
  The Parent sponsors a stock option plan which provides for the granting of
stock options to substantially all employees of the Parent and its wholly
owned and majority owned subsidiaries, including the Companies. Options are
generally granted at a price (established by the Parent's board of directors
based on equity transactions and other analyses) equal to at least 100% of the
fair market value of the Parent's common stock on the option grant date.
Options granted generally become exercisable 40% after two years and 20% per
annum for the next three years and remain exercisable for ten years after the
option grant date. At December 31, 1996, employees of the Companies held
outstanding options for a total of 314,768 of the Parent's shares at option
prices ranging from $7.60 to $30.50 per share.
 
 Statement of Financial Accounting Standards No. 123
 
  During 1995, the Financial Accounting Standards Board issued SFAS No. 123,
"Accounting for Stock- Based Compensation," which defines a fair value-based
method of accounting for an employee stock option or similar equity instrument
and encourages all entities to adopt that method of accounting for all of
their employee stock compensation plans. However, it also allows an entity to
continue to measure compensation cost for those plans using the method of
accounting prescribed by Accounting Principles Board ("APB") Opinion No. 25,
"Accounting for Stock Issued to Employees." Entities electing to remain with
the accounting methodology required by APB Opinion No. 25 must make pro forma
disclosures of net income and, if presented, earnings per share as if the fair
value-based method of accounting defined in SFAS No. 123 had been applied.
 
  The Parent has elected to account for its stock based compensation plans
under APB Opinion No. 25, under which no compensation cost has been recognized
by either the Parent or the Companies. However, the Companies have computed,
for pro forma disclosure purposes, the value of all options for shares of the
Parent's common stock granted since December 15, 1994 to employees of the
Companies using the Black-Scholes option pricing model prescribed by SFAS No.
123 and the following weighted average assumptions:

  The weighted average fair value of options for the Parent's stock granted to
employees of the Companies in 1995 and 1996 was $16.14 and $19.65 per share,
respectively. The total value of options for the Parent's stock granted to
employees of the Companies during 1995 and 1996 was computed as approximately
$257,000 and $4,116,000, respectively, which would be amortized on a pro forma
basis over the five-year vesting period of the options. If the Companies had
accounted for these plans in accordance with SFAS No. 123, the Companies' net
loss for the years ended December 31, 1995 and 1996 would have increased as
follows:

  Because SFAS No. 123 has not been applied to options granted prior to
December 15, 1994, the resulting pro forma compensation cost may not be
representative of that expected in future years.

10. COMMITMENTS AND CONTINGENCIES
 
 Purchase Commitments
 
  At December 31, 1996, the Companies had entered into agreements with vendors
to purchase approximately $5.6 million of equipment related to the
installation of a switch in Columbia, South Carolina, improvements to a switch
in Birmingham, Alabama, and other network expansion efforts.
   
  At June 30, 1997, the Companies had entered into agreements with vendors to
purchase approximately $11.5 million of equipment related to the improvement
and installation of switches, other network expansion efforts and certain
services (unaudited).     
 
 Legal Proceedings
       
  In the normal course of business, the Companies are subject to various
litigation; however, in management's opinion and the opinion of counsel, there
are no legal proceedings pending against the Companies which would have a
material adverse effect on the financial position, results of operations, or
liquidity of the Companies.
 
11. EMPLOYEE BENEFIT PLANS
 
  The Fiber Companies' employees are participants in the Parent's defined
benefit plan. Effective January 31, 1995, the Parent elected to freeze all
future benefit accruals under the plan. The plan provided retirement,
disability, and survivor benefits to eligible employees. The Fiber Companies
funded pension cost in accordance with applicable regulations. Total pension
cost charged to expense in 1994, 1995, and 1996 was $17,805, $8,721, and
$9,600, respectively.
 
  The net assets available for benefits under the plan are maintained by the
Parent on behalf of its subsidiaries. As of December 31, 1995 and 1996, the
plan's net assets available for benefits were $1,878,498 and $1,646,892,
respectively, and the projected benefit obligations were $2,370,391 and
$2,442,917, respectively, as computed under SFAS No. 87.
 
  Employees of the Fiber Companies participate in the Parent's 401(k) defined
contribution plan. This plan, which became effective February 1, 1995, covers
all employees of the participating entities who have one year of service and
are 18 years of age. The Parent contributes a discretionary amount of the
employees' earnings based on the plan's earnings. The discretionary
contribution percentages per employee for the years ended December 31, 1995
and 1996 were 2.53% (limited to a total for all participants of $100,000) and
2.66% (limited to a total for all participants of $150,000), respectively, and
were fully funded by the Parent. 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
by the Fiber Companies for the years ended December 31, 1995 and 1996 were
$26,520 and $54,098, respectively.
 
  Employees of DeltaCom may participate in a separately administered 401(k)
defined contribution plan. The plan covers substantially all DeltaCom
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 IRS
regulations. DeltaCom has elected to provide matching employer contributions
equal to the lesser of 3% of compensation or the maximum amount annually for
each participant. DeltaCom's policy is to fund contributions as earned.
Company contributions made to the plan and charged to expense by DeltaCom for
the 11 months ended December 31, 1996 were $123,854.

12. RELATED PARTY TRANSACTIONS
   
  The Parent occasionally provides certain administrative services, such as
legal and tax planning services for its subsidiaries, including the Companies.
In addition, for the period from January through July 1994, the Parent
provided FiberNet and InterQuest with additional administrative services,
including marketing, management, and financial services. The costs of these
services are charged to the Companies based primarily on the salaries and
related expenses for certain of the Parent's executives and an estimate of
their time spent on projects specific to the Companies. For the years ended
December 31, 1994, 1995, and 1996, the Companies recorded $148,140, $5,270,
and $19,150 in selling, operations, and administration expenses related to
these services. In the opinion of management, the methodology used to
calculate the amounts charged to the Companies is reasonable.     
 
  The Parent also leases office space and transportation to the Companies.
Amounts charged to the Companies related to these leases for the years ended
December 31, 1995 and 1996 were $21,669, and $62,762, respectively, and are
reflected as selling, operations, and administration expenses in the
Companies' statements of operations. No such leases were in place in 1994. See
Notes 7 and 11 for discussion of certain other financial arrangements between
the Parent and the Companies.
   
  Certain of the Parent's other wholly owned or majority-owned subsidiaries
provide the Companies with various services and/or receive services provided
by the Companies. These entities include Interstate Telephone Company and
Valley Telephone Company, which provide local and long-distance telephone
services; InterCall, Inc. ("InterCall"), which provides conference calling
services; and InterServ Services Corporation, which provides operator services
for "800" customer service numbers and full-service marketing research in the
telecommunications industry and other industries. The Parent also holds equity
investments in the following entities which do business with the Companies:
InterCel, Inc., which provides cellular services; KNOLOGY Holdings, Inc.,
formerly CyberNet Holding, Inc. ("KNOLOGY"), which provides cable television
services; and MindSpring Enterprises, Inc. ("MindSpring"), which is a regional
provider of Internet access. In management's opinion, the Companies'
transactions with these affiliated entities are generally representative of
arm's-length transactions.     
 
  For the years ended December 31, 1994, 1995, and 1996, the Companies
received services from these affiliated entities in the amounts of $89,149,
$465,167, and $180,400, respectively, which are reflected in selling,
operations, and administration expenses in the Companies' statements of
operations. In addition, in 1996, the Companies received services from these
affiliated entities in the amount of $762,173, which is reflected in cost of
services in the Companies' statements of operations. At December 31, 1995 and
1996, amounts payable for these services of $577,439 and $658,990,
respectively, are recorded in the Companies' balance sheets as affiliate
accounts payable.
 
  The Fiber Companies provide operator and directory assistance services and
lease capacity on certain of their fiber routes to affiliated entities.
Beginning in 1996, DeltaCom also provides long-distance and related services
to the Parent and all of its wholly owned and majority-owned subsidiaries.
Also beginning in 1996, DeltaCom acts as an agent for InterCall and MindSpring
in contracting with major interexchange carriers to provide origination and
termination services. Under these agreements, DeltaCom contracts with the
interexchange carrier and rebills the appropriate access charges plus a margin
to InterCall and MindSpring, such that only the margin impacts the Companies'
combined revenues. Total affiliated revenues included in the Companies'
statements of operations for the years ended December 31, 1994, 1995, and 1996
were $458,302, $486,246, and $2,863,389, respectively. At December 31, 1995
and 1996, amounts receivable for these services were $84,796 and $1,227,661,
respectively, and are recorded in the Companies' balance sheets as affiliate
accounts receivable.
   
  In 1995, the Fiber Companies constructed a fiber route on behalf of
CyberNet. Construction expenses reimbursed by KNOLOGY totaled $62,830. The
Companies also provided certain engineering and construction- related
management services to KNOLOGY in 1995. The Fiber Companies did not bill
KNOLOGY for these services, which are estimated by the Fiber Companies to have
a value of approximately $50,000.

  DeltaCom has a contract with a former stockholder to provide management
services to DeltaCom through 1997 for $300,000 annually. In addition, DeltaCom
leases real properties from former stockholders and other related parties.
Total rental expense related to these leases was approximately $235,000 in
1996. DeltaCom is obligated to pay rentals to a former stockholder totaling
approximately $181,000 annually from 1997 through 2005 under leases which are
cancelable by either of the parties with 24 months' notice. DeltaCom is also
obligated through 1999 to pay annual rentals ranging from approximately
$74,000 to $81,000 to an officer of a former stockholder.
 
  Relatives of stockholders of the Parent are stockholders and employees of
the Companies' insurance provider. The costs charged to the Companies for
insurance services from this provider were $40,351, $63,836, and $156,523 for
the years ended December 31, 1994, 1995, and 1996.
   
  The chief executive officer of the Fiber Companies, who has been named as
chief executive officer of ITC/\DeltaCom, has also served since July 15, 1996
as president and chief executive officer and as a director of KNOLOGY. He has
served in his capacity as chief executive officer and president of KNOLOGY at
the request of KNOLOGY and the Parent and received no compensation from
KNOLOGY for the year ended December 31, 1996. He resigned as chief executive
officer and president of KNOLOGY effective February 20, 1997. The value of
services provided through February 20, 1997 is estimated to total
approximately $20,000.     
 
13. ACQUISITION OF DELTACOM
 
  On January 29, 1996 (the "Acquisition Date"), DeltaCom was purchased by the
Parent for total consideration of $71,362,213, including cash acquired of
$1,828,121 (the "Acquisition"). The consideration included $65,362,213 in cash
and $6,000,000 in common stock of the Parent. Simultaneously, the Parent
refinanced $8,643,384 of DeltaCom's outstanding debt by borrowing against its
own line of credit and contributing the proceeds to DeltaCom, which then
repaid all of its outstanding debt. The Acquisition was accounted for under
the purchase method of accounting, and the purchase accounting entries were
"pushed down" to DeltaCom's financial statements. The purchase price has been
allocated to the underlying assets purchased and liabilities assumed based on
their estimated fair values at the Acquisition Date. The acquisition costs
exceeded the fair market value of net tangible assets acquired by $54,645,063,
of which $5,464,506 has been allocated to identifiable intangible assets and
the remainder has been recorded as goodwill in the accompanying balance
sheets. Amounts recorded in connection with the "pushdown" include the
$49,180,557 in goodwill, $5,464,506 in customer base, $74,005,598 in debt
related to the Acquisition and debt refinancing, and $6,000,000 in paid-in
capital. The operating results of DeltaCom have been included in the
Companies' financial statements since the Acquisition Date.
 
  The following table summarizes the net assets purchased in connection with
the Acquisition and the amount attributable to cost in excess of net assets
acquired:

  The following pro forma information has been prepared assuming that the
Acquisition occurred at the beginning of the respective periods. This
information includes pro forma adjustments related to the amortization of
goodwill resulting from the excess of the purchase price over the fair value
of the net assets acquired and interest expense related to the debt financing
used to acquire DeltaCom. The pro forma information is presented for
informational purposes only and may not be indicative of the results of
operations as they would have been had the Acquisition occurred at the
beginning of the respective periods, nor is the information necessarily
indicative of the results of operations which may occur in the future.

16. SUBSEQUENT EVENTS
 
 Acquisition
 
  On March 27, 1997, the Parent purchased the 64% interest in Gulf States
owned by SCANA, along with certain of SCANA's other fiber and fiber-related
assets, including a significant long-term customer contract (the "Georgia
Fiber Assets"), for approximately $28 million payable at closing, plus certain
contingent consideration. The purchase price included 588,411 shares of the
Parent's convertible, nonvoting preferred stock valued at approximately $17.9
million and an unsecured purchase money note for approximately $10 million
(the "SCANA Note"). The purchase price was allocated as follows: $17 million
to the 64% interest in Gulf States and $10.9 million to the Georgia Fiber
Assets. The note, which bears interest at 11%, is payable in ten semiannual
principal payments of approximately $1 million plus accrued interest,
beginning September 30, 1997. The contingent consideration is due no later
than April 30, 1998, at which time the Parent must deliver additional
preferred stock to SCANA equal to 35.7% of (a) 64%, multiplied by (b)(i) 6,
multiplied by (ii) 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 $11,265,696.
   
  Upon the closing of these acquisitions, the Parent contributed the 64%
ownership interest in Gulf States to GSTS and the Georgia Fiber Assets to
FiberNet. The Gulf States partnership has been dissolved. The SCANA Note was
assumed by FiberNet and the Parent was released from its obligations
thereunder.

 GSTS Bridge Facility
   
  In connection with the acquisition of the remaining 64% interest in Gulf
States, GSTS refinanced Gulf States' outstanding indebtedness of approximately
$41.6 million. In connection with the refinancing, GSTS wrote off $818,572
($507,515 net of tax benefits) in unamortized debt issuance costs, which is
reflected on the accompanying statement of operations as an extraordinary loss
on extinguishment of debt. The GSTS Bridge Facility matured on the date the
proceeds from ITC/\DeltaCom's debt offering described below were released (July
25, 1997). The GSTS Bridge Facility bore interest at LIBOR plus 2.25%.     
   
 ITC/\DeltaCom Employee Stock Option Plan     
   
  Upon the Reorganization, all employees of the Companies became eligible to
receive stock options under ITC/\DeltaCom's 1997 Employee Stock Option Plan
(the "Stock Option Plan") which was adopted and approved by its sole
stockholder 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 Internal Revenue
Code of 1986, as amended (the "Code") to employees of ITC/\DeltaCom, its
subsidiaries obtained in the reorganization described in Note 1, and the
Parent, 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 ITC/\DeltaCom. The Stock Option Plan authorizes the issuance of up
to 1.5 million shares of Class A Common Stock pursuant to options granted
under the Stock Option Plan (subject to anti-dilution adjustments in the event
of a stock split, recapitalization or similar transaction). The maximum number
of shares subject to options that can be awarded under the Stock Option Plan
to any person is 500,000 shares. The Compensation Committee of ITC/\DeltaCom's
Board of Directors will administer the Stock Option Plan and will grant
options to purchase Class A 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
Class A 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 Class A 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 Class A 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 Class A Common Stock). There is also a $100,000 limit
on the value of Class A 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.     
   
  ITC/\DeltaCom's Board of Directors may amend or terminate the Stock Option
Plan with respect to shares of Class A Common Stock as to which options have
not been granted.     
   
  On March 24, 1997, ITC/\Deltacom granted options to purchase 789,000 shares
of Class A 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 ($7.20) as determined by ITC/\DeltaCom's sole stockholder's
board of directors based on equity transactions and other analyses.     
   
  On July 29, 1997, ITC/\DeltaCom granted options to purchase 105,254 shares of
Class A 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 ($7.20) as determined by ITC/\DeltaCom's sole stockholder's board
of directors based on equity transactions and other analyses.

 Directors Stock Option Plan     
   
  On March 24, 1997, ITC/\DeltaCom adopted and its stockholders approved the
Directors Stock Option Plan (the "Directors Plan"). The Directors 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
ITC/\Deltacom who are not officers or employees of the Company, the Parent, or
any subsidiary of ITC/\DeltaCom (each an "Eligible Director"). The Directors
Plan authorizes the issuance of up to 150,000 shares of Class A Common Stock
pursuant to options granted under the Directors Plan (subject to anti-dilution
adjustments). The option exercise price for options granted under the
Directors Plan will be at least 100% of the fair market value of the shares of
Class A Common Stock on the date of grant of the option. Under the Directors
Plan, each Eligible Director will be granted an option to purchase 10,000
shares of Class A 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, ITC/\DeltaCom granted options to purchase 10,000 shares of
ITC/\DeltaCom's Class A Common Stock to each of its six nonemployee directors.
All options were granted at a price equal to the estimated fair value of the
common stock on the date of grant ($7.20) as determined by the ITC/\DeltaCom's
stockholder's board of directors based on equity transactions and other
analyses.     
 
 Credit Facility
   
  FiberNet has entered into a commitment letter with a third-party lender for
a five-year term and revolving credit facility of up to $100 million which
will be used for working capital and other purposes, including capital
expenditures and permitted acquisitions. The Credit Facility will include a
$50 million multi-draw term facility and a $50 million revolving credit
facility. Obligations under the credit facility are expected to be guaranteed
by ITC/\DeltaCom and the Companies and are expected to be secured by
substantially all current and future assets and properties of the Companies.
The Credit Facility is expected to contain a number of covenants applicable to
the Companies, including, among others, covenants limiting debt to be
incurred, dividends to be paid, as well as other equity distributions or stock
repurchases and covenants requiring compliance with certain financial ratios.
    
 Debt Offering
   
  On June 3, 1997, ITC/\DeltaCom completed the issuance of 11% Senior Notes due
2007 (the "Offering").     
   
  Proceeds from the Offering 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
$48.0 million of the Companies' advances from Parent and approximately $41.6
million under the GSTS Bridge Facility as well as accrued interest.
Approximately $62.7 million of such proceeds are held by the Trustee as
security for and to fund the first six interest payments on the Senior Notes.
Also in connection with the Reorganization, FiberNet undertook to repay (and
DeltaCom agreed to reimburse to FiberNet) the remaining $31.0 million of
DeltaCom's advance from Parent; the Parent then forgave this indebtedness and
contributed it to FiberNet as additional equity. Upon the settlement of
DeltaCom's advance from Parent related to the acquisition (and accrued
interest), the Parent Credit Facility was amended to release the Companies as
guarantors and to terminate the related security interests in the assets of
the Companies (Note 7). The Parent effected the Reorganization on July 25,
1997.

                         NOTES TO FINANCIAL STATEMENTS
 
                DECEMBER 31, 1994 AND 1995 AND JANUARY 29, 1996
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  DeltaCom, Inc. (the "Company") was incorporated in the state of Alabama on
April 7, 1982. The Company is a provider of telecommunications services and
products in Alabama and surrounding states. Prior to January 29, 1996, the
Company's common stock was owned 50% by SCI Systems (Alabama), Inc., 14% by
Brindlee Mountain Telephone Company ("BMTC"), and 36% by the majority
stockholder of BMTC. ITC Holding Company, Inc. acquired all of the stock of
the Company on January 29, 1996 (Note 7).
 
 Basis of Accounting
 
  The accompanying financial statements are prepared on the accrual basis of
accounting. Revenues are recognized as services are performed. Costs and
expenses are recognized when incurred. The financial statements are prepared
in conformity with generally accepted accounting principles, which require the
use of estimates. Actual results may differ from those estimates.
 
 Accounting Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from these estimates.
 
 Depreciation
 
  Depreciation of property and equipment is generally provided on a composite
or straight-line basis over the assets' estimated useful lives, which are 40
years for buildings, 5 to 20 years for telecommunications equipment, 3 to 15
years for office furniture and equipment, and 5 years for vehicles.
 
  Expenditures for maintenance and repairs are expensed currently, while
renewals and betterments that materially extend the life of an asset are
capitalized. The cost of assets sold, retired, or otherwise disposed of and
the related accumulated depreciation are eliminated from the accounts, and any
resulting gain or loss is included in the results of operations.
 
 Income Taxes
 
  Deferred income taxes are determined in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes." This
approach results in the recognition of deferred tax assets and liabilities for
the expected future tax consequences of temporary differences between the book
carrying amounts and the tax basis of assets and liabilities.
 
 Advertising Costs
 
  The Company expenses all advertising costs as incurred.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Gulf States FiberNet:
 
  We have audited the accompanying balance sheets of GULF STATES FIBERNET (a
Georgia general partnership) as of December 31, 1995 and 1996 and the related
statements of operations, partners' capital, and cash flows for period from
inception (August 17, 1994) through December 31, 1994 and for the years ended
December 31, 1995 and 1996. These financial statements are the responsibility
of the Partnership's management. Our responsibility is to express an opinion
on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Gulf States FiberNet as of
December 31, 1995 and 1996 and the results of its operations and its cash
flows for the period from inception (August 17, 1994) through December 31,
1994 and for the years ended December 31, 1995 and 1996 in conformity with
generally accepted accounting principles.

1. ORGANIZATION AND BUSINESS OPERATIONS
 
 General
 
  Gulf States FiberNet (the "Partnership") was formed on August 17, 1994
pursuant to the provisions of the Georgia Uniform Partnership Act. The
Partnership provides digital communications transport to communications common
carriers in the states of Georgia, Texas, Alabama, Mississippi, and Louisiana.
The Partnership is a facilities-based entity with an existing fiber optic
transmission facility between Atlanta, Georgia, and Birmingham, Alabama. The
Partnership has also constructed a redundant route from Atlanta to Birmingham
which continues on to Longview, Texas, through such cities as Tuscaloosa,
Alabama; Meridian, Jackson, and Vicksburg, Mississippi; and Monroe and
Shreveport, Louisiana. The Partnership has also constructed a spur from
Meridian to Gulfport, Mississippi. These additional routes became operational
during May 1995. In September 1996, an extension to Longview, Texas, was
completed. The Partnership has also constructed a route from Atlanta to
Gainesville, Georgia, where it connects to the network of another
nonaffiliated entity that provides transit into the networks of several other
nonaffiliated entities in the states of North Carolina and South Carolina. The
Atlanta to Gainesville route was completed in January 1996.
 
  The general partners and their respective ownership percentages as of
December 31, 1996 were as follows:
 
<TABLE>
           <S>                                            <C>
           SCANA Communications, Inc. ("SCANA")..........  64%
           Gulf States Transmission Systems, Inc.
            ("GSTS").....................................  36
</TABLE>
 
  GSTS is the managing partner and is responsible for managing and operating
the Partnership. The partners make capital contributions to share in the
operating results of, and receive distributions from, the Partnership in
accordance with their respective ownership percentages.
 
  The Partnership's revenues are derived from sales to a relatively small
number of customers. The loss of a major customer would have a significant
impact on the partnership's results of operations and financial position. This
risk is mitigated by take-or-pay contracts whereby the customers are
contractually obligated to pay periodic specified amounts, even if they do not
take delivery of the contracted services.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Accounting and Presentation
 
  The Partnership's financial statements are prepared on the accrual basis of
accounting. The balance sheet as of March 27, 1997 and the statements of
operations and cash flows for the periods ending March 31, 1996 and March 27,
1996 are unaudited and, in the opinion of management, contain all adjustments
(consisting of only normal recurring items) necessary for the fair
presentation of the financial position and results of operations for the
interim periods. The results of operations for the period ended March 27, 1997
are not necessarily indicative of the results to be expected for the entire
year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the 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
 
  For purposes of the statements of cash flows, temporary investments
represent securities with maturities of 90 days or less and are considered
cash equivalents.

 Revenue Recognition
 
  Revenues are recognized as the Partnership performs services in accordance
with contract or tariff terms.
 
 Property and Equipment
 
  Property and equipment are carried at cost or fair market value of
contributed property at the time of the contribution. Depreciation and
amortization of property and equipment are provided using the straight-line
method over estimated useful lives (3 to 20 years). Balances of major classes
of assets and the related accumulated depreciation as of December 31, 1995 and
1996 are as follows:

 Long-Lived Assets
 
  In 1995, the Partnership adopted Statement of Financial Accounting Standards
("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of." SFAS No. 121 establishes accounting
standards for the impairment of long-lived assets and goodwill related to
those assets to be held and used and for long-lived assets and certain
identifiable intangibles to be disposed of. The effect of adopting SFAS No.
121 was not material.
 
  The Partnership periodically reviews the values assigned to long-lived
assets, such as property and equipment, and cost in excess of net assets
acquired to determine whether any impairments are other than temporary.
Management believes that the long-lived assets in the accompanying balance
sheets are appropriately valued.
 
 Income Taxes
 
  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, no
provision for federal or state income taxes has been made in the accompanying
financial statements.
 
 Interest Expense
 
  All interest incurred during 1994, 1995, and 1996 is attributable to the
construction of the routes detailed in Note 1. Interest was capitalized until
the completion of the construction of a specific route segment. The amount of
interest capitalized in 1994, 1995, and 1996 totaled $45,907, $1,020,204, and
$40,365, respectively.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Other Noncurrent Assets
 
  The excess of cost over the fair market value of assets acquired
("goodwill") is being amortized to income on a straight-line basis over a
period of 40 years.
 
  In connection with the issuance of its long-term debt, the Partnership
incurred debt issuance costs of approximately $986,000 and $80,000 in 1995 and
1996, respectively. These costs were recorded as other assets and are being
amortized on a straight-line basis over 7 to 8.5 years, the term of the
related debt facilities.
 
 Presentation
 
  Certain prior year amounts have been reclassified to conform with the
current year presentation.
 
3. SCANA ASSET CONTRIBUTION
 
  Effective November 1, 1994, SCANA contributed an existing Atlanta to
Birmingham fiber optic route to the Partnership as part of its capital
contribution. The tangible assets associated with this route were recorded at
their estimated appraised value of $4,924,410. This route was valued at
$5,449,670 for purposes of determining a portion of SCANA's capital
contribution. The $525,260 difference between the estimated appraised value of
the tangible assets and the fair market value of the route is reflected as
goodwill in the accompanying balance sheets.
 
4. INTERIM CONSTRUCTION LOAN AND LONG-TERM DEBT
 
 Interim Construction Loan
 
  On December 8, 1994, the Partnership completed a $40,000,000 construction
loan commitment ("Loan") with NationsBank of North Carolina. The Loan provided
the Partnership the ability to draw amounts as needed to finance the
construction of a new route. The interest rates paid on amounts outstanding
under the Loan ranged from 6.75% to 7.25% in 1995. Any unused portion of this
Loan was subject to a commitment fee equal to .25% per annum. The Partnership
borrowed $36,700,000 under this Loan prior to its repayment in full in August
1995. The Partnership utilized funds realized from the $47,500,000 nonrecourse
project financing discussed below to repay the Loan.
 
 Long-Term Debt
   
  Long-term debt consisted of the following at December 31, 1996 and March 27,
1997:

  On July 25, 1995, the Partnership completed a $47,500,000 nonrecourse
project financing (the "Financing") with NationsBank of North Carolina. The
Financing is to be repaid in 16 equal semiannual installments of $2,968,750
beginning on June 30, 1996 and ending on December 31, 2003. The Financing
bears

interest on outstanding amounts at various floating rate options plus an
applicable credit spread, which varies throughout the term of the Financing.
The Partnership is contractually obligated to select the three-month LIBOR
option as a direct result of the interest rate swap agreement discussed below.
The Financing is secured by substantially all of the Partnership's assets.
 
  Concurrent with the closing of the Financing, the parent companies of GSTS
and SCANA, ITC Holding Company, Inc. ("ITC") and SCANA, Inc., respectively,
have entered into the Telecommunications System Capacity Agreement ("TSCA")
with NationsBank of North Carolina ("NationsBank"). The TSCA requires ITC and
SCANA to make additional equity contributions to the Partnership. These
required equity contributions are calculated on a quarterly basis throughout
the term of the Financing based on a contractually determined amount, less the
Partnership's quarterly revenue, excluding the nonrecurring revenue discussed
in Note 7. The contractually determined amounts discussed above are fixed
amounts and are not contingent upon the results of operations of the
Partnership.
 
  On January 24, 1995, the Partnership entered into a forward starting
interest rate swap agreement with a $47,500,000 principal amount with
NationsBank. This agreement is accounted for as a hedge of an anticipated
transaction. The agreement swaps the applicable three-month LIBOR selected
under the Financing with a fixed rate of 8.25%. As of December 31, 1996, the
Partnership would be required to pay $2,962,000 to terminate the interest rate
swap with NationsBank. The Partnership made payments totaling $1,261,000 and
$553,320 to NationsBank in 1995 and 1996, respectively, in connection with
this interest rate swap. These payments are included in interest expense in
the accompanying statements of operations.
 
  As a result of this interest rate swap, the Financing will bear an effective
interest rate as follows:

6. RELATED-PARTY TRANSACTIONS
 
  ITC provides certain administrative services and leases office space to the
Partnership. In addition, certain of ITC's other wholly owned or majority-
owned subsidiaries provide the Partnership with various services and/or
receive services provided by the Partnership. These entities include
Interstate Telephone Company and Valley Telephone Company, which provide local
and long distance telephone services; Interstate FiberNet, which provides
digital communications transport; and InterQuest, which provides operator
assistance services. ITC also holds equity investments in the following
entities which do business with the Partnership: InterCel, Inc., which
provides cellular services, and MindSpring Enterprises, Inc., which is a
regional provider of Internet access.
 
  The Company received services from ITC and other affiliated entities of
approximately $279,000, $1,162,000, and $1,477,000, for the period from
inception through December 31, 1994 and the years ended December 31, 1995 and
1996, respectively, which are reflected in selling, general, and
administrative expenses in the Partnership's statements of operations. In
addition, the Partnership received services from ITC and other affiliated
entities of approximately $70,000 for the year ended December 31, 1996, which
is reflected in cost of services in the Partnership's statement of operations.
At December 31, 1995 and 1996, amounts payable for these services of $0 and
$25,263, respectively, are recorded in the Partnership's balance sheets as
affiliate accounts payable. In management's opinion, the Partnership's
transactions with these affiliated entities are representative of arm's-length
transactions.
 
  Relatives of stockholders of ITC are stockholders and employees of the
Partnership's insurance provider. The costs charged to the Partnership for
insurance services were approximately $1,300, $33,000, and $54,000 for the
years ended December 31, 1994, 1995, and 1996, respectively.
 
7. SIGNIFICANT CUSTOMERS
 
  No customer was responsible for greater than 10% of the Partnership's
revenues for the period from inception through December 31, 1994. However, two
customers made up greater than 10% of the Partnership's revenues for the years
ended December 31, 1995 and 1996, as follows:

  During 1995, the Partnership received nonrecurring revenue of $3,250,000, or
approximately 43% of net sales to Customer A, related to the cancellation of
an existing lease agreement.
 
  The Partnership entered into an agreement with Customer A to lease certain
fiber optic lines whereby Customer A is contractually obligated to pay
$4,338,996 per annum for 11 years beginning June 1995.
 
8. SUBSEQUENT EVENTS
 
 Capital Lease
 
  In January 1997, the Partnership entered into a capital lease agreement with
Southern Telecom 1, Inc. ("STI") to construct and lease a fiber optic facility
and related equipment from Birmingham to Montgomery, Alabama. In total, STI
constructed a 24 fiber optic strand facility, 12 strands of which it leased to
the Partnership and 12 strands of which it granted the Partnership a revocable
right to use. STI has the option to lease to the

Partnership any of the additional 12 licensed fibers for a monthly payment of
$2,000 per fiber after the ninth anniversary of the lease. To the extent STI
does not lease the Partnership at least six of the licensed fibers under its
option, the Partnership will have the right to lease from STI up to a total of
six of the licensed fibers. Construction was completed and lease payments
began in February 1997. Payments under the lease are as follows:

 Dissolution of the Partnership
 
  On March 27, 1997, GSTS's parent, ITC, purchased the 64% interest in the
Partnership owned by SCANA for approximately $17 million, payable at closing
in shares of ITC's nonvoting convertible preferred stock, plus certain
contingent consideration. The contingent consideration is due no later than
April 30, 1998, at which time ITC must deliver additional nonvoting
convertible preferred stock to SCANA equal to 35.7% of (a) 64%, multiplied by
(b) (i) 6, multiplied by (ii) the amount, if any, by which the earnings before
interest, taxes, depreciation, and amortization of the Partnership for the
year ended December 31, 1997 exceed $11,265,696.
 
  Upon the closing of the acquisition, ITC contributed the 64% ownership
interest in the Partnership to GSTS and the Partnership was dissolved.
 
 Debt Refinancing
   
  In connection with the acquisition of the remaining 64% interest in the
Partnership, GSTS signed an agreement with NationsBank of Texas, N.A. for a
$41.6 million bridge financing facility (the "Bridge Facility"). The Bridge
Facility finances the Partnership's existing Financing described in Note 4 and
is secured by the assets of the Partnership. The Bridge Facility bore interest
on outstanding amounts at various floating rate options plus an applicable
credit margin. The Bridge Facility matured and was repaid on the date the
proceeds from ITC/\DeltaCom's debt offering discussed later were released.     
 
 Parent's Reorganization of Subsidiaries
   
  In March 1997, ITC formed a new wholly owned subsidiary, ITC/\DeltaCom, Inc.
("ITC/\DeltaCom"). Upon completion of the debt offering and the related
transactions described below, ITC reorganized several of its wholly owned
subsidiaries as follows:     
     
  .  Eastern Telecom, Inc. (d.b.a. InterQuest) and ITC Transmission Systems
     II, Inc. merged with and into Interstate FiberNet, Inc., formerly ITC
     Transmission Systems, Inc. ("FiberNet").     
     
  .  ITC contributed all of the outstanding capital stock of FiberNet,
     DeltaCom, Inc. and GSTS to ITC/\DeltaCom.     
     
  .  ITC/\DeltaCom contributed all of the outstanding capital stock of
     DeltaCom and GSTS to FiberNet.     
 
  These changes are collectively referred to as the "Reorganization."
 
 ITC/\DeltaCom Debt Offering
   
  On June 3, 1997, ITC/\DeltaCom issued senior notes with a principal value of
$200 million (the "Offering"). Proceeds from the Offering were held by the
trustee until all required regulatory approvals related to the Reorganization
were received. Upon consummation of the Reorganization on July 25, 1997, a
portion of the proceeds was used to repay the Bridge Facility described above
as well as certain advances from the Parent outstanding at DeltaCom, Inc.

                         INDEPENDENT AUDITORS' REPORT
 
SCANA Communications, Inc.
 
  We have audited the accompanying balance sheets of Georgia Fiber (a business
unit of SCANA Communications, Inc. (SCI)) as of December 31, 1996 and 1995,
and the related statements of income and net equity and of cash flows for the
years then ended. These financial statements are the responsibility of SCI's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. 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, such financial statements present fairly, in all material
respects, the financial position of Georgia Fiber at December 31, 1996 and
1995 and the results of its operations and its cash flows for the years then
ended in conformity with generally accepted accounting principles.
 
  The accompanying financial statements have been prepared from the separate
records of Georgia Fiber (a business unit of SCANA Communications, Inc.) and
may not necessarily be indicative of the conditions that would have existed or
the results of operations that would have occurred had Georgia Fiber been
operated as an unaffiliated company.
 
  As discussed in Note 1 to the financial statements, on March 27, 1997, the
assets of Georgia Fiber were sold.

                    YEARS ENDED DECEMBER 31, 1996 AND 1995
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  General--Georgia Fiber is a business unit of SCANA Communications, Inc.
("SCI"). This business unit consists of certain fiber optic capacity in the
State of Georgia. Such assets were sold to a third party on March 27, 1997.
The accompanying financial statements include the historical cost basis assets
and related operations of the business unit. No effects of the asset sale are
included in the financial statements.
 
  All revenues were derived from fiber optic service provided to one customer.
Revenues are recognized as earned on a monthly basis in accordance with an
agreement with such customer.
 
  Use of Estimates--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the 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.
 
  Fiber Optic Transmission Capacity--Pursuant to certain agreements, SCI
(formerly MPX Systems, Inc.) obtained fiber optic transmission capacity along
specified routes in Georgia. Such agreements obligated SCI to reimburse the
counterparty for costs incurred in construction of the capacity and to pay for
operation and maintenance costs applicable to the capacity. In addition, SCI
pays an amount equal to 2.8% of operating income from operations to the
counterparty. Since inception, additional costs have been incurred to upgrade
and extend the life of the capacity. Costs of obtaining, constructing,
upgrading and extending the life of the capacity are capitalized. Of the
capitalized cost at December 31, 1996, approximately $6,231,000 is being
amortized over a useful life of 25 years and approximately $9,308,000 is
amortized over a life of 8 years. Costs of operating and maintaining the
capacity are expensed as incurred. These agreements expire in 2015 with two
ten-year renewal options.
 
  Cost and Expenses--The accompanying financial statements reflect costs and
expenses that are applicable to the business unit and selling, general and
administrative expenses of SCI which were allocated to the business unit based
on revenues. Management believes that the method used to allocate such
expenses is reasonable (see Note 3).
 
  Fair Value of Financial Instruments--The carrying values of the Company's
financial instruments (receivables and payables) approximate fair value.
 
  Income Taxes--SCI is a wholly owned subsidiary of SCANA Corporation. As a
business unit of SCI, Georgia Fiber does not incur income tax expense. On a
pro forma separate return basis, for the year ended December 31, 1996,
management estimates that Georgia Fiber would have incurred an income tax
provision of approximately $615,000.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS     
   
  Under Section 145 of the Delaware General Corporation Law ("DGCL"), a
corporation may indemnify its directors, officers, employees and agents and
its former directors, officers, employees and agents and those who serve, at
the corporation's request, in such capacities with another enterprise, against
expenses (including attorneys' fees), as well as judgments, fines and
settlements, actually and reasonably incurred in connection with the defense
of any action, suit or proceeding in which they or any of them were or are
made parties or are threatened to be made parties by reason of their serving
or having served in such capacity. The DGCL provides, however, that such
person must have acted in good faith and in a manner such person reasonably
believed to be in (or not opposed to) the best interests of the corporation
and, in the case of a criminal action, such person must have had no reasonable
cause to believe his or her conduct was unlawful. In addition, the DGCL does
not permit indemnification in an action or suit by or in the right of the
corporation, where such person has been adjudged liable to the corporation,
unless, and only to the extent that, a court determines that such person
fairly and reasonably is entitled to indemnity for costs the court deems
proper in light of liability adjudication. Indemnity is mandatory to the
extent a claim, issue or matter has been successfully defended.     
   
  The Company's Certificate of Incorporation (the "Certificate") contains
provisions that provide that no director of the Company shall be liable for
breach of fiduciary duty as a director except for (1) any breach of the
directors' duty of loyalty to the Company or its stockholders; (2) acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of the law; (3) liability under Section 174 of the DGCL; or
(4) any transaction from which the director derived an improper personal
benefit. Under the Bylaws of the Company, the Company is required to advance
expenses incurred by an officer or director in defending or participating in
any action which such director or officer is made a party to or is threatened
to be made a party to by reason of his or her serving or having served as an
officer or director if the director or officer undertakes to repay such amount
if it is determined that the director or officer is not entitled to
indemnification. In addition, the Company intends to enter into indemnity
agreements with each of its directors pursuant to which the Company will agree
to indemnify the directors as permitted by the DGCL.

ITEM 22. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions,
 
                                     II-6
<PAGE>
 
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
  The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this Registration Statement through
the date of responding to the request.
 
  The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in
this Registration Statement when it became effective.
   
  The undersigned registrant hereby undertakes to file, during any period in
which offers or sales are being made, a post-effective amendment to this
Registration Statement;     
     
    (i) to include any prospectus required by section 10(a)(3) of the
  Securities Act;     
     
    (ii) to reflect in the prospectus any facts or events arising after the
  effective date of this Registration Statement (or the most recent post-
  effective amendment hereof) which, individually or in the aggregate,
  represents a fundamental change in the information set forth in this
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any

                                THIRD AMENDMENT

                                      TO 

                     THE INTERCONNECTION AGREEMENT BETWEEN
                              DELTACOM, INC. AND
                      BELLSOUTH TELECOMMUNICATIONS, INC.
                             DATED MARCH 12, 1997



     Pursuant to this Agreement (the "Third Amendment"), DeltaCom, Inc. 
("DeltaCom") and BellSouth Telecommunications, Inc. ("BellSouth") hereinafter 
referred to collectively as the "Parties", hereby agree to amend that 
Interconnection Agreement between the Parties dated March 12, 1997 
("Interconnection Agreement").

     NOW THEREFORE, in consideration of the mutual provisions contained herein 
and other good and valuable consideration, the receipt and sufficiency of which 
are hereby acknowledged, the Parties hereby covenant and agree as follows:

     1.  The Parties agree that the resale restrictions set forth in Section 
III.A. of the first Amendment to the Interconnection Agreement dated March 12, 
1997 between BellSouth and DeltaCom shall be deleted.

     2.  The Parties agree that the only restrictions on resale shall be those 
set forth in the Second and Final Order of the Arbitrators in the AT&T/MCI 
interconnection arbitrations, Docket Numbers 96-01152 and 96-01271 (the 
"Arbitrations"). (See pp. 13-18 of Second and Final Order dated January 23, 
1997, attached hereto as Exhibit A.)

     3.  The Parties agree that all of the other provisions of the 
Interconnection Agreement shall remain in full force and effect. Nothing in this
Third Amendment shall in any way limit DeltaCom's ability to select and 
substitute more favorable rates or terms of Section XXII, entitled Most 
Favorable Provisions, of the Interconnection Agreement.

     4.  The Parties acknowledge that the terms of this Third Amendment were 
established as a result of orders of the Tennessee Regulatory Authority ("TRA")

execution of this Amendment and its submission to the TRA is made without 
prejudice to the rights of BellSouth to challenge any decision of the TRA in the
Arbitrations, and to the extent DeltaCom intervenes in the Arbitrations, 
execution of this Third Amendment and its submission to the TRA is made without 
prejudice to the rights of DeltaCom to challenge any decision of the TRA in the 
Arbitrations. The parties further agree to conform this Third Amendment to any 
subsequent order of the TRA relating to any of the rates, terms and conditions 
affected by this Third Amendment.

ISSUE 1:   "WHAT SERVICES PROVIDED BY BELLSOUTH, IF ANY, SHOULD BE EXCLUDED FROM
           RESALE?"/(15)/

COMMENTS AND DISCUSSION:
- -----------------------

           On November 14, 1996, the Arbitrators ordered that all services 
provided by BellSouth, with the exception of short-term promotions, as that term
is defined below, should be made available for resale, including specifically,
but without limiting the foregoing, long-term promotions, as that term is
defined below, LifeLine Services, Link-Up Services, grandfathered or obsoleted
services, 911 Services, contract service arrangements, and state-specific
discount plans. In other words, the Arbitrators answered the question presented,
by a unanimous vote, as follows: that no service provided by BellSouth shall be
excluded from resale, except short-term promotions.

        With regard to the resale of 911 Services, each of the Arbitrators 
recognized the importance of the service and that 911 boards should not be 
excluded from the benefits which may be derived from competition. They cautioned
not only those subject to the provisions of any order of arbitration award, but
also the 911 boards in the State of Tennessee, to preserve, protect, and verify
that the effectiveness and integrity of the emergency systems will not be harmed
if they choose to change telecommunications carriers.

        Finally, Director Malone added that restrictions on cross-class selling 
are permissible restrictions on the services available for resale./(16)/



- ---------------
/(15)/ The motion was made by Chairman Greer and amended by Director Malone. The
motion, as amended, was seconded by Director Malone and passed unanimously.

/(16)/ This matter was also covered in the motion made by Director Kyle in Issue
2. Both the amendment which Director Malone made to the motion of Chairman Greer
in Issue 1 and the motion of Director Kyle in Issue 2 passed unanimously. The
order on this aspect has been reduced to writing in Paragraph 13.

<PAGE>
 
          On December 3, 1996, the Arbitrators voted unanimously to adopt the 
language proposed by BellSouth with regard to contract service arrangements, 
nonrecurring charges, and inside wire maintenance./17/

ORDERED:
- --------
          8.   That all services provided by BellSouth, with the exception of 
short-term promotions, as that term is defined below, should be, and hereby are,
made available by BellSouth for resale to AT&T and MCI.
          
          9.   That the following terms and conditions on short-term and 
long-term promotions are reasonable and necessary, and shall be implemented:

               a.   Short-term promotions be, and hereby are, defined as those 
promotions that are offered for a ninety (90) day period or less, and which 
are not offered on a consecutive basis;

               b.   Long-term promotions be, and hereby are, defined as those 
promotions that are offered for more than ninety (90) days;

               c.   In order to prohibit any abuse or potential abuse of the
provision that short-term promotions are not available for resale, BellSouth may
not offer a series of the same or substantially similar short-term promotions;

               d.   Long-term promotions may be obtained by AT&T or MCI at one 
of the following rates:
        
                    (1)  the stated tariff rate, less the wholesale discount;



- ---------------------
/17/ Chairman Greer made the motion on the Final Best Offer.  It was seconded by
Director Kyle and unanimously approved.

                                      14

















<PAGE>
 
             (2)  the promotional rate (the promotional rate offered by 
BellSouth will not be discounted further by the wholesale discount rate):

         e.  When AT&T or MCI obtains a long-term promotional offering at the 
promotional rate, they will only be permitted to obtain the promotional rate 
for the period that the promotion is offered by BellSouth.  At the time the 
promotion ends, if AT&T or MCI chooses to continue obtaining the applicable 
service, they must obtain that service at the stated tariff rate, less the 
wholesale discount;

         f.  AT&T and MCI can only offer a promotional rate for a service 
obtained subject to the provisions of this Paragraph 8 to customers who would 
have qualified for the promotional rate if the service were being offered by 
BellSouth;

         g.  Any benefit of the promotion must be realized within the time 
period of the promotion and BellSouth may not use promotional offerings to 
evade the wholesale obligation.  If AT&T  or MCI believes that such abuse is 
occurring, they may file a petition with the Authority challenging the promotion
and, if such petitions are many in number, the Directors of the Authority may
contemplate the establishment of specific rules governing promotional discounts,
which may include, not only the provisions listed above, but also additional
rules or, in the alternative, the Directors may consider making all promotions
available for resale.

    10.  That the following terms and conditions on the resale of LifeLine 
Services are reasonable and necessary, and shall be implemented:

         a.  AT&T and MCI shall only offer LifeLine Service to customers who 
meet the qualifications outlined in the "means test";

                                      15
<PAGE>
 
               b.   LifeLine Services and rates shall be offered by AT&T or MCI 
in a manner similar to the manner in which LifeLine Services are offered in the 
market today, that is through a discount to BellSouth's Message Rate Service, 
General Subscriber Tariff A3.2.4;/16/

               c.   AT&T and MCI shall purchase BellSouth's Message Rate Service
at the stated tariff rate, less the wholesale discount. AT&T and MCI must 
further discount the wholesale Message Rate Service to LifeLine customers with a
discount which is no less than the minimum discount that BellSouth now provides;

               d.   The maximum rate which AT&T and MCI may charge for LifeLine 
Service shall be capped at the retail flat rate offered by BellSouth;

               e.   BellSouth shall charge the federally-mandated Subscriber 
Line Charge (currently $3.50) to AT&T and MCI;/19/

               f.   AT&T and MCI are required to waive the Subscriber Line 
Charge for the end-user;

               g.   AT&T and MCI are responsible for recovering the Subscriber 
Line Charge from the National Exchange Carriers Association's interstate toll 
settlement pool just as BellSouth does today.

          11.  That the following terms and conditions on the resale of Link-Up 
Service are reasonable and necessary, and shall be implemented:

               a.   AT&T and MCI may offer Link-Up Service only to those 
customers who meet the qualifications outlined in the "means test";


- -------------------
/16/  However, if a competitor has a proposal that it believes is just and
reasonable, the competitor may file the proposal with the Authority for
consideration.
/19/  See FCC Report and Order, Paragraph 983.




                                      16

<PAGE>
 
               b.   AT&T and MCI must further discount the Link-Up Service by at
least the percentage that is now offered by BellSouth;

               c.   AT&T and MCI are responsible for recouping the additional
discount in the same manner as BellSouth does today.

          12.  That AT&T and MCI may only offer grandfathered services to
customers or subscribers who have already been grandfathered. Grandfathered
services may not be resold to a new or different group of customers or
subscribers.

          13.  That, while BellSouth has been ordered to make 911 Services
available for resale, AT&T and MCI are cautioned to preserve the integrity of
911 Services.

          14.  That the Final Best Offer proposed by BellSouth with regard to
contract service arrangements, nonrecurring services, and inside wire
maintenance, attached hereto as Exhibit "A" and made a part hereof by reference,
be, and hereby is, approved and adopted by the Arbitrators.

ISSUE 2:  WHAT TERMS AND CONDITIONS, INCLUDING USE AND USER RESTRICTIONS, IF 
          ANY, SHOULD BE APPLIED TO RESALE OF BELLSOUTH SERVICES?/20/

COMMENTS AND DISCUSSION:
- -----------------------

          On November 14, 1996, the Arbitrators answered the question presented 
by unanimous vote. Director Kyle, in making the motion, stated that in light of 
the FCC's referring to limitations as "presumptively unreasonable," she wished 
to adopt only the restrictions stated in the FCC Report and Order, i.e., no 
resale of access, no resale to independent pay phone providers, and no cross-
class selling./21/ Chairman Greer stated that he concurred with Director Kyle's
motion, but wanted to amend it by adding that AT&T and MCI must resell services
in compliance with the applicable terms and conditions in BellSouth's retail
tariffs. Director Malone further stated that the applicable terms and conditions
in the tariffs must be just, reasonable, and nondiscriminatory as required by
the Act.

          On December 3, 1996, the Arbitrators ordered that the contract 
language negotiated by and between BellSouth and AT&T to comply with the 
Arbitrators' First Order and to resolve any remaining unresolved issues under 
Issue 2 shall also be used by MCI and BellSouth in their Innerconnection 
Agreement./22/

ORDERED:

          15.  That no terms and conditions, including use and user 
restrictions, will be applicable to the resale of BellSouth services, except

based upon the Act at Section 251(c)(4).

/22/ Director Malone's motion on December 3, 1996, was seconded by Chairman 
Greer and was passed by the unanimous vote of the Arbitrators.

product of the Stated Compensation Rate [_____________________] multiplied
by the airline miles ("ALMs") between the a point of presence and z point of
presence (where a and z constitute the points of interconnection with the
Customer or the Customer's access provider). In the case of Capacity provided
under this Agreement where either or both of the a point of presence or the z
point of presence (described above) are located in a Tier II or Tier III city,
Stated Compensation shall be the sum of (i) the product of the Stated
Compensation Rate [_______________________] multiplied by the ALMs between b
point of presence and y point of presence (where b and y constitute points of
interconnection between designated Tier I cities (designated in Schedule 3.5));
(ii) the product of the Stated Compensation Rate [__________________________]
multiplied by the ALMs between the b point

                                       3

of presence (described above) and the a point of presence (where a constitutes
the interconnection with the Customer or Customer's access provider in a Tier II
or Tier III city); and (iii) the product of the Stated Compensation Rate
[_________________________] multiplied by the ALMs between y point of presence
(described above) and the z point of presence (where z constitutes the point of
interconnection with the Customer or Customer's access provider in a Tier II or
Tier III city). The Stated Compensation Rate will be the applicable rate for
Capacity on the then current Stated Compensation Rate Schedule for the city
pairs between which Service is to be provided. Each Party shall designate the
applicable tier for each of its cities. The governing tier of a city pair shall
be the higher tier number of the designated tier applicable to each city. The
initial Stated Compensation Rate Schedule and the designated Tier I cities are
attached to this Agreement as Schedule 3.5. As frequently as necessary, but not
less than at six month intervals, the Committee may revise the Stated
Compensation Rate Schedule. Notwithstanding the provisions of this Section, a
Seller may charge a Customer a price based on a rate in excess of or below the
applicable Stated Compensation Rate Schedule for Service provided under this
Agreement. However, subject to Article VII, the Provider's minimum Compensation
shall be computed utilizing the Stated Compensation Rate.

the provision of point-to-point telecommunications transport in accordance with
industry standards.

     4.2  Liability for Interruption. The Provider's liability to Seller
          --------------------------                                    
shall be limited to a credit, as provided in Section 7.4 herein, for
Interruption unless the Interruption is the result of gross negligence or
willful misconduct by the Provider, its employees, agents, or contractors. Any
claim or demand for credit as a result of any Interruption shall be waived
unless presented in writing within six months after the date of the
Interruption.

     4.3  Capacity, Service and Testing. Provider agrees to properly maintain 
           -----------------------------                             
Capacity covered by this Agreement. Upon execution of this Agreement, CFN and
IFN shall each appoint two persons to develop standards and requirements for the
provision of Capacity under this Agreements (the "Standards"). Such Standards

     5.1  Seller's Use.  The Seller shall be permitted to use Capacity
          ------------                                                
operated and maintained by the Provider and contracted for under this Agreement
only to provide Capacity for sale to a Customer. Capacity purchased under this
Agreement must be the subject of actual contracts or agreements for Service with
a Customer and may not be purchased under this Agreement at wholesale for
eventual resale pursuant to unexecuted contracts or agreements with existing or
future Customers. In the event the Provider asserts that the Seller is violating
the provisions of this Section and the Parties cannot resolve the conflict
between themselves, the Provider may name three certified public accountants to
review the applicable contracts to determine the Seller's compliance with this
Section. The Seller shall designate one of the three named certified public
accountants to audit the applicable contracts and shall make such contracts
available to the named certified public accountant. The Provider shall be
responsible for the certified public accountant's fees and expenses, unless the
certified public accountant determines this Section 5.1 is being violated. In
such a case, the Seller shall be responsible for the certified public
accountant's fees and expenses.

          -------                                                       
as-required basis in conformance with the requirements developed pursuant to
Section 6.3. Seller agrees to provide the Provider with a twenty four (24) hour,
seven day a week technical contact.

                                 JOINT DUTIES

     6.1  Sales Efforts. Each Party shall use reasonable efforts to market and

sell Service to potential Customers.

     6.2  Sales Materials; Information Regarding Service. The Seller shall
          ----------------------------------------------                  
obtain the written approval of the Provider prior to distribution of any
advertising, promotional or sales materials or other publicity concerning the
Provider and/or its Affiliates with respect to Service offered pursuant to this
Agreement and the relationship between the Parties under this Agreement.
However, if the Seller does not receive written notice of the Provider's
objection to any submitted advertising, promotional or sales materials, within
three business days of Provider's receipt at the place for notices contained in
Section 10.13 of this Agreement, the Provider will be deemed to have given
written approval of such advertising, promotional or sales materials. The Seller
shall make no representations or warranties concerning Service, except as
specifically authorized by the Provider.

     6.3  Contract Provisions. Subject to the Standards developed pursuant to
          -------------------                                             
Section 4.3, the Seller shall determine the provisions which shall be included
in all contracts for Services to Customers. However, no contract shall contain a
provision which authorizes its termination with

                                       5
<PAGE>
 
less than thirty (30) days notice to the Seller. Further, without the written
consent of the Provider, no contract shall be for a term which extends beyond
January 31, 2004.

     6.4  Force Majeure. Neither Party shall be held liable for any delay
          -------------

its control and without its fault or negligence, such as acts of God, acts of
civil or military authority, government regulations, embargoes, epidemics, war,
terrorist acts, riots, insurrections, fires, explosions, earthquakes, nuclear
accidents, floods, strikes, power blackouts, volcanic action, other major
environmental disturbances, unusually severe weather conditions, or acts or
omissions of transportation common carriers (collectively referred to as "Force
Majeure Conditions").

                           COMPENSATION AND BILLING

     7.1  Linear System Compensation. With respect to Network Revenue to
          --------------------------                                    
be derived from each sale of Service, the Seller shall pay the Provider a fee
equal to the product of the Stated Compensation multiplied by a fraction. The
numerator of the fraction shall be the carriage distance attributable to the
Provider providing facilities to the route producing such Network Revenue, and
the denominator shall be the sum of the carriage distance attributable to the
Provider providing facilities to the route producing such Network Revenues and
the carriage distance attributable to the Seller providing facilities to the
route producing such Network Revenue. Carriage distance attributable to the
Service producing such Network Revenue shall be determined in airline miles
(ALMs) between the meet point of the Parties' networks ([____] V & H coordinates
of [________]) and the point of presence constituting the interconnection with
the Customer or the Customer's access provider. For example, in the case of a
sale of Capacity over a linear route where the carriage distance attributable to
Provider is 20 ALMs, and attributable to Seller is 30 ALMs, the Seller shall pay
to the Provider 40% (20/50) of the Stated Compensation.

     7.2  Ring System Compensation. Reserved.
          ------------------------           

     7.3  Bonus Compensation. In addition to Compensation paid pursuant to
          --------------------                                            
Sections 7.1 and 7.2, to the extent that the Network Revenue attributable to the
Provider provided Capacity is greater than the Stated Compensation attributable
to such Provider (computed according to the principles enunciated in Sections
7.1 and 7.2), the Seller shall pay the Provider a Bonus Compensation fee equal
to [_] multiplied by the difference between the Network Revenue attributable to
the Provider provided Capacity (computed according to the principles enunciated
in Sections 7.1 and 7.2) and the Stated Compensation attributable to such
Provider.

     7.4  Compensation and Interruptions. In case of any Interruption to any
          ------------------------------------                             
Capacity provided by Provider under this Agreement, if not due to the negligence
of the Seller or its customers, the following rules shall apply:

                                       6
<PAGE>
 
               (a)  If the customer's contract contains an Interruption Credit
                    enumerated on Exhibit 7.4, Seller shall be credited for an
                    Interruption at the rate as provided in the affected
                    Customers' contracts. Notwithstanding the previous sentence,
                    neither Party will enter a contract with a Customer (who is
                    not a Customer on the date of the execution of this
                    Agreement) which provides for an interruption credit
                    enumerated in category B or F of Exhibit 7.4, unless the
                    Party receives written consent of the other Party. However,
                    in no event shall the Interruption Credit exceed an amount
                    equal to the Compensation that would have been payable to
                    the Provider with respect to such interrupted Capacity.

               (b)  The Interruption allowance applies only to the Capacity
                    interrupted.

               (c)  A credit allowance is not applicable for any period during
                    which Seller or its Customer fails to afford access to
                    Capacity provided by Provider for the purpose of
                    investigations and clearing troubles.

     7.5  Billing and Collection. The Seller will be responsible for billing
          ----------------------------                                 
and collection of its Customer accounts. The Seller may contract for billing and
collection.
           
     7.6  Commissions.  There will be no sales commission to the Seller for
          -----------------                                               
selling Capacity on the Provider's system.

     7.7  Payment of Compensation. Compensation will be payable to the Provider 
          ---------------------------                                    
within 20 days of the end of the month in which the Service was provided to the
Customer. With respect to payable Compensation, the Seller shall issue to the
Provider on a circuit by circuit basis a detailed statement indicating the
Compensation to be paid with respect to such Service. In the event the Provider
asserts that the Seller has miscomputed the amount of payable Compensation and
the Parties cannot resolve the conflict between themselves, the Provider may
name a certified public accountant to review the applicable contracts and
computations of the payable Compensation. The Party requesting the audit shall
be responsible for the certified public accountant's fees and expenses.

     7.8  Late Payment.  Any payment of Compensation received after the
          ------------------                                              
required payment date, described in Section 7.7 of this Agreement, will be
subject to a late payment charge. A late payment charge shall accrue on all
outstanding amounts as of each required payment date (as described in Section
7.7 of this Agreement). The late payment charge shall equal the amount due on
the required payment date multiplied by one and one half percent (1 1/2 %)
multiplied by the number of required payment dates which have passed since the
accrual of the liability for the payment of such Compensation.
                 
     7.9  Installation Fees and Cancellations.  Upon each required payment
          -----------------------------------------                          
date (as described in Section 7.7 of this Agreement), the Seller shall pay the
Provider the following

                                       7
<PAGE>
 
installation fees with respect to Capacity with an in-service date (as
originally requested by the Customer) occurring in the prior month:

          (a)  with respect to Capacity where the a point of presence and the z
     point of presence (as described in Section 3.5) are both located in a Tier
     I city and where the Seller does not charge an installation fee, [______];

          (b)  with respect to Capacity where the a point of presence and the z
     point of presence (as described in Section 3.5) are both located in a Tier
     I city and where the Seller charges an installation fee, an installation
     fee equal to the [________________] multiplied by a fraction with a
     numerator equal to the airline miles (ALMs) between either the a or z point
     of presence (where either the a or z point of presence constitutes the
     point of interconnection with the Customer or Customer's access provider in
     the Provider's territory) and the Meet Point (described in Section 3.4) and
     the denominator equal to the ALMs between the a point of presence and the z
     point of presence (described in Section 3.5); and

          (c)  with respect to Capacity where either both of the a point of
     presence or the z point of presence are located in a Tier II or Tier III
     city, an installation fee equal to [__] for each DS- 1 and [__] for each
     DS-3.

In the event the contract is canceled less than ten days prior to the planned
in-service date (as originally requested by the Customer), the Seller shall pay
the Provider an amount equal to the applicable installation fee for the
Capacity. Additionally, in the event the contract is canceled prior to the
expiration of 30 days of the in-service date (as originally required by the
Customer), the Seller shall pay to the Provider an amount equal to the
applicable installation fee for the Capacity less amounts paid to the Provider
under the contract.

               strictly advisory and shall not be binding on the Parties, nor
               will any opinion expressed by the mediator be admissible in any
               arbitration or other proceeding. The mediator may either be
               chosen from a previously selected list, or by other agreement of
               the Committee. Costs of mediation shall be borne equally by the

     9.2  Arbitration.
          ----------- 
          
          (a)  If any dispute refereed to the Committee has not been resolved
               within thirty (30) days after the date of referral to the
               Committee, or if a Party is not satisfied with the decision of
               the Committee, a Party may submit the dispute to arbitration
               according to the Commercial Arbitration Rules of the American
               Arbitration Association. Each Party to the dispute shall select
               an arbitrator and the two so selected shall name a third. All
               arbitrators selected shall be members of the American Arbitration
               Association. The arbitrators shall be impartial and familiar with
               the telecommunications industry, and shall not have been employed
               by or affiliated with any of the Parties hereto or any of their
               respective Affiliates. The arbitration procedure may be initiated
               by any Party by written notice to the other Parties, and such
               notice shall specify in reasonable detail the dispute being
               submitted to arbitration. The Parties hereby renounce all
               recourse to litigation and agree that the award of the
               arbitrators shall be final and subject to no judicial review. The
               arbitrators shall conduct the proceedings, including arguments
               and briefs, pursuant to the Commercial Arbitration Rules of the
               American Arbitration Association, as now or hereafter amended
               (the "Rules"); provided that the provisions of this Agreement
               shall prevail in the event of any conflict between the Rules and
               the provisions of this Agreement. The panel of arbitrators shall
               decide the

                                       11
<PAGE>
 
               issues submitted to them in accordance with the provisions and
               commercial purposes of this Agreement, provided that all
               substantive questions of law shall be determined under the laws
               of the State of North Carolina (without regard to the principles
               of conflicts of laws of such jurisdiction). All questions and
               issues in connection with the dispute, including procedural
               issues, shall be decided by the concurrence of at least two
               arbitrators, and all decisions shall be in writing and submitted
               to all parties.

          (b)  In no event shall any Party be entitled to receive, and the
               arbitrators shall not be empowered to award, punitive or
               exemplary damages. Each Party hereby irrevocably waives any claim
               or right for or to punitive or exemplary damages.

          (c)  The Parties shall facilitate the arbitration by: (i) making
               available to one another and to the arbitrators for examination,
               inspection and extraction all documents, books, records and
               personnel under their control if determined by the arbitrators to
               be relevant to the dispute; (ii) conducting arbitration hearings
               to the greatest extent possible on successive days; and (iii)
               observing strictly the time periods established by the Rules or
               by the arbitrators for submission of evidence or briefs.

          (d)  In the final award, the panel of arbitrators shall divide all
               cost, other than fees of counsel incurred in conducting the
               arbitration, in such manner as the panel deems just and equitable
               under the circumstances. Judgment on the award of the panel of
               arbitrators may be entered in any court having jurisdiction over
               the party against which enforcement of the award is being sought.
               Each Party hereby irrevocably submits and consents to the
               jurisdiction of any such court for the purpose of rendering a
               judgment on any such award.

          (e)  Each Party agrees that any award of the panel of arbitrators
               against it and on which judgment is entered as provided in the
               preceding subsection (d) may be executed against the assets of
               such Party in any jurisdiction. By execution of the Agreement,
               each Party hereby irrevocably submits to the jurisdiction of any
               court in any such jurisdiction in any legal action or proceeding
               relating to such executions.

          (f)  Each Party hereby irrevocably waives, to the fullest extent
               permitted by law, any objection it may now or hereafter have to
               any suit, action or proceeding, arising out of or relating to
               this Agreement that is brought in any of the jurisdictions
               designated in the preceding subsections (d) and (e) for the
               purposes envisioned by those subsections, and hereby further
               irrevocably waives any claim that any such suit, action or
               proceeding so brought has been brought in any inconvenient forum.

     WHEREAS, FPC is willing, during the term of this Agreement, to grant to IFN
the use of certain dark fiber as herein provided, where such use will not

     B.   Upon receipt of a request for service from IFN, the parties shall
          consult in good faith concerning the request, giving due consideration
          to the then-existing and projected electric transmission and
          distribution and telecommunication requirements of FPC and to such
          other factors as they may reasonably deem relevant. Following such
          consultation, if FPC can accommodate the request FPC will furnish to
          IFN an estimate of annual fee requirements and anticipated Fiber
          Acceptance Date(s) (Exhibit A) for IFN's review and acceptance. In
          addition, FPC will furnish an estimate of any FPC Make-Ready (Exhibit
          B) that is necessary in order to safely and properly install the Cable
          and support the Route Segment for IFN's review and acceptance.

     C.   Upon receipt of IFN's acceptance of the above and payment for any FPC
          Make-Ready necessary and upon acceptance by FPC, all appropriate
          Exhibits shall be attached hereto and made a part hereof and FPC will
          exercise its best efforts to provide the IFN Fibers to IFN in
          accordance therewith FPC further agrees to provide written
          notification to IFN upon availability of the IFN Fibers.

4.1  Acceptance of IFN Fibers. Upon completion of construction of the Cable and
     ------------------------                                                  
     any FPC Make-Ready, FPC will Acceptance Test the IFN Fibers to insure that
     the IFN Fibers meet or exceed the Fibers specifications outlined in Exhibit
     C. In the event the IFN Fibers meet such specifications, FPC shall notify
     IFN in writing of the availability of the IFN Fibers (the Fiber Notice).
     Within 5 business days of IFN receiving the Fiber Notice, IFN shall give
     FPC written notice of any failure of the IFN Fibers to satisfy IFN's
     Acceptance Test

     If IFN gives FPC written notice of such failure, FPC shall use its best
     commercial efforts to promptly correct such failure, whereupon IFN and FPC
     shall jointly conduct another Acceptance Test This procedure shall be
     repeated until all IFN Fibers meet or exceed the specifications outlined in
     Exhibit C.

     In the event deficiencies continue to be identified after the third round
     of testing, IFN may, at its option, conditionally accept the IFN Fibers
     and, upon such conditional acceptance, commence payment of the fees as set
     forth in Exhibit A and according to Section 5A. FPC will correct any such
     deficiencies within sixty (60) days of conditional acceptance.

     If IFN does not give FPC written notice of such failure within 5 business
     days of IFN receiving the Fiber Notice, it shall be deemed that IFN has
     accepted the IFN Fibers.

     The day in which IFN has accepted the IFN Fibers will be considered the
     Fiber Acceptance Date, and fees referenced in Section 5A and specified in
     Exhibit A shall commence on this date.

     In the event an Off-Network Route Segment(s) is not constructed in time for
     the Acceptance Test of the remaining Route Segment(s) identified in Exhibit
     A, Section 12 shall apply with respect to that Off-Network Route Segment
     and FPC and IFN shall proceed with this Section 4.1, including testing and
     acceptance of those Route Segments completed. In such event, this Section
     4.1 shall be repeated for such Off-Network Route Segment subject to Section
     12 when and if such Segment is completed.

5.   Price and Payment
     -----------------

     A.   Subject to the allowances for interruptions set forth in Section 8
          hereof, IFN shall pay FPC a license fee for the use of the IFN Fibers
          provided by FPC, said fee to commence On the actual Fiber Acceptance
          Date. The term and fee amount payable to FPC for the IFN Fibers shall
          be as shown on attached Exhibit(s) A or as amended. Said fees shall be
          payable monthly, in advance, on the first day of each month. Should
          the Fiber Acceptance Date be any date other than the first of the
          month, then that initial month's fee shall be prorated based on the
          actual date.

     B.   Unless a payment is disputed in good faith, if for any reason IFN is
          delinquent in the payment of any amounts due to FPC under this
          Agreement for more than thirty (30) days, after written notice of the
          past due amount IFN shall pay interest on such unpaid amount from the
          date such payment is due until such payment is made. The interest rate
          shall be the lesser of 18% per annum or the maximum permitted by law.

     C.   Upon execution of this Agreement, IFN will advance FPC a non-
          refundable (except as provided in Section 12.2(B)) amount equal to
          three month's license fee for each Exhibit A approved by FPC and
          accepted by IFN in accordance with Section 4 of this Agreement. The
          advance shall be considered as prepayment toward IFN's first year
          obligation in the initial term under Section 5A.

     D.   Rates applicable to any renewal term shall be specified on the
          attached Exhibit D.

     property of FPC. Legal title shall be held by FPC. Neither the provision of
     the use of IFN Fibers by FPC to IFN hereunder, nor the payments by IFN
     contemplated hereby, shall create or vest in IFN any easement, interest or
     any other ownership or property right of any nature in the Cable, except
     FPC warrants, subject to the provisions of this Agreement, IFN's right to
     use the IFN Fibers for lawful telecommunications transmission purposes
     during the term of this Agreement pursuant to the provisions of this
     Agreement IFN shall not grant any security interest in the IFN Fibers or
     any part or component thereof.

7.   Use of Fiber; Taxes, Franchises and Easements.
     ------ -------------------------------------- 
     A.   IFN warrants that its use of the IFN Fibers shall at all times be in
          compliance with all certifications, licenses, permits, etc., as
          required by proper regulatory authority and that IFN shall not use,
          provide the use, or receive a fee for the use of the IFN Fibers or
          capacity to others without having obtained such authorization.

     B.   FPC shall be responsible for and shall pay any and all taxes or fees
          with respect to the construction or operation of the FPC Cable,
          including, but not limited to, any sales, use, franchise or excise tax
          however designated, levied or based, which taxes or fees are (i)
          imposed or assessed prior to the Acceptance Date, or (ii) imposed or
          assessed (regardless of time) solely with respect to the FPC Cable in
          exchange for the approval of construction or in the granting of an
          interest in public property or a public right-of-way relating to the
          situation of the FPC Cable in public right-of-way. Any fees incurred
          by reason of the use of the IFN Fibers or the provision of
          telecommunication services by IFN within a local jurisdiction shall be
          the responsibility of IFN. IFN shall be responsible for and shall pay
          any and all taxes or fees, including franchise fees, imposed as a
          result of its use of the IFN Fibers pursuant to this Agreement. IFN
          shall, at its own expense, obtain all municipal street franchise
          rights that may be required for the use of the IFN Fibers thereof by
          IFN. IFN shall be responsible for and shall pay any and all taxes or
          fees, including but not limited to, any sales or use tax, levied or
          based on the payment of the license fee set forth in Section 5A, but
          excluding, however, any federal or state income taxes due by FPC
          resulting from receipt of the license fee and excluding any ad valorem
          taxes due on the IFN Fibers and the IFN Premises owned by FPC.

     C.   Other than as set forth in Section 7A and 7B, FPC shall be
          responsible, at its own expense, for the acquisition of any easement
          or rights-of-way rights that may be required in order to permit the
          installation of the Cable; FPC shall use its best commercial effort,
          including, if necessary, reasonable legal efforts to obtain such
          rights; provided, however, nothing herein shall be deemed as
          obligating FPC to pay any exorbitant or grossly disproportional amount
          for the acquisition of such rights.

     D.   During the term of this Agreement, FPC may use or permit the use of
          the FPC Fibers and the telecommunication capacity thereof for any
          lawful purpose. Nothing in this Agreement shall be construed or
          interpreted to prohibit FPC from leasing or licensing the use of the
          FPC Fibers or otherwise providing telecommunications capacity to
          others or from installing or permitting others to install additional
          Fibers or telecommunication capacity, including without limitation,
          fiber optic telecommunication capacity, within the right-of-way
          constituting any Route Segment or to prohibit FPC from operating such

          telecommunication capacity (alone or in combination with others) in
          competition with the IFN Fibers; provided however, that no such
          installation or operation shall interfere with IFN's use of the IFN
          Fibers and the telecommunication capacity thereof.

     E.   IFN shall not provide the use, receive a fee for the use, or sublease
          any or all of the IFN Fibers to any entity without first obtaining the
          prior written consent of FPC. FPC shall not unreasonably withhold its
          approval of said request from IFN. In the event that IFN receives
          approval to sublease any or all of the IFN Fibers, and the sublease
          amount is in excess of the amount paid by IFN to FPC, FPC will be
          entitled to an amount equal to the difference between the sublease
          amount and the lease amount paid to FPC by IFN. This Section shall not
          be deemed as precluding IFN from leasing capacity on the IFN Fibers to
          others without the prior written consent of FPC.

8.   Performance and Maintenance.
     --------------------------- 

     A.   FPC warrants and agrees that the provision of the IFN Fibers hereunder
          shall be in conformity with and shall comply with all the requirements
          of this Agreement, that such provision shall be made in a good and
          workmanlike manner and in accordance with industry standards in order
          to enable IFN to provide the telecommunication service. FPC further
          warrants and agrees that the IFN Fibers shall meet or exceed the
          specifications outlined in Exhibit C.

     B.   FPC agrees to perform periodic inspections of the Cable and supporting
          structures. FPC further agrees to perform periodic inspections,
          testing, and any and all maintenance required for the provision of the
          IFN Fibers and to maintain and provide adequate spare equipment and
          parts as is appropriate for its obligations hereunder. FPC will make
          every effort to schedule service-affecting work from midnight to 6
          A.M. on Sunday morning and Monday morning during the first and third
          weekends of each month, excluding the period beginning two days prior
          to Thanksgiving and ending on the following January 3. FPC will notify
          IFN as per Exhibit F.

     C.   In the event of any interruption of provision of the IFN Fibers to IFN
          (Outage), FPC shall furnish immediate notice to IFN, and shall specify
          in such notice the nature and cause of the interruption, the extent of
          the repairs required, and the estimated time to restore, as per
          Exhibit F. FPC further agrees to use its best efforts to restore the
          provision of the IFN Fibers on an expedited basis, and to restore the
          Route Segment and any splicing of the IFN Fibers in a systematic and
          rotational manner, with IFN Fibers having equal priority to other
          Fibers within the Cable; every attempt will be made to dispatch repair
          technicians to the affected site within 2 hours, and to keep the
          Outage to less than 12 hours provided however, that nothing herein
          shall be construed to preclude FPC from giving higher priority to the
          restoration or preservation of electric power service (including
          without limitation the restoration or preservation of communications
          capability that in FPC's judgment is immediately necessary to the
          provision of electric power service) than to the restoration of
          service hereunder. in the event an Outage exceeds 24 hours, FPC will
          extend to IFN a credit equal to one day's license fee (to be
          considered 1/30th of the then current monthly rate) for each
          consecutive 24- hour Outage interval, or fraction thereof, in excess
          of the initial 24 hours. (e.g. 26-hour Outage = 1 day credit; 40-hour
          Outage = 1 day credit; 50-hour Outage = 2 day credit). The credit
          shall be applied to the subsequent month's license fee payment.

     D.   In the event repeater equipment is needed, FPC and IFN will specify a
          mutually appropriate location(s) (Regeneration Facility Location(s))
          for FPC to install and maintain an enclosure for the purpose of
          housing such repeater equipment. Specifications for the enclosure and
          the location of this Regeneration Facility Location(s) shall be
          outlined in Exhibit E. Such location(s) may or may not be collocated
          at an existing FPC location(s). FPC shall be responsible for the
          purchase, operation, maintenance, and repair, of all enclosures, HVAC,
          and associated backup power equipment at Regeneration Facility
          Locations, except as outlined in Exhibit E. IFN shall be responsible
          for costs, if any, associated with the preparation of repeater
          location(s) as specified in Exhibit E.

     E.   IFN shall be solely responsible, at its own expense, for the purchase,
          installation, operation, maintenance and repair of all IFN equipment
          and IFN facilities required in connection with the use of the IFN
          Fibers.

     F.   IFN may request that FPC splice into the IFN Fibers at additional, 
          pre-existing splice points in the future, subject to FPC's approval,
          not to be unreasonably withheld. IFN will schedule all such splicing
          activities with FPC at a mutually agreed-upon time. All such splicing
          will be performed by FPC, and IFN shall reimburse FPC for all FPC 
          Make-Ready costs as defined in Section 3H and outlined in a Make-Ready
          cost estimate FPC shall furnish to IFN upon such request of additional
          splice(s).

9.   Alteration of Route. Whenever, during the term of this Agreement, it may be
     -------------------                                                        
     necessary or desirable from the standpoint of FPC's electric utility
     operations to do so, or if required by public authorities or by a final
     order or decree of a court or administrative agency, FPC may, upon
     reasonable notice to IFN, relocate all or any part of the Cable to one or
     more alternate routes or rights-of-way (inducing without limitation
     replacing overhead cable with underground cable, or replacing underground
     cable with overhead cable, if such replacement is in connection with an
     abandonment, relocation or replacement of electric transmission facilities
     over, under, on, upon or in which the Cable has been installed). [_________
     ___________________________________________________________________________
     _____________________________________________________________________]. In 
     such event, FPC shall give IFN as much prior notice as reasonably
     practicable, and the parties shall cooperate to accomplish the transfer of
     service over the Cable to the new route or right-of-way so as to minimize
     any interference with the use of the IFN Fibers or the FPC Fibers by either
     party and to avoid unreasonably impairing the ability of each to provide
     telecommunication service of the type, quality and reliability contemplated
     by this Agreement.

                   manner, or acquiesce in writing to, any petition filed

                   written notice from FPC to IFN specifying such

                   within such 30-day period with the exercise of reasonable due

                   in this Agreement or the IFN Fibers, without the prior
                   written consent of FPC; provided that nothing herein shall be

            (i)    FPC shall (1) apply for or consent to the appointment of, or
                   the taking of possession by a receiver, custodian, trustee or

12.2 Rights Upon Default
     ----------- -------

     A.   Upon the occurrence of an Event of Default by IFN, FPC shall be
          entitled to immediate and exclusive possession, use and control of the
          IFN Fibers and may forthwith terminate this Agreement by written
          notice to IFN. Upon the occurrence of an Event of Default IFN's right
          to possession and use of the IFN Fibers shall terminate and FPC shall
          have the right to repossess the IFN Fibers by any lawful means,
          without demand or notice of any kind to IFN except as may be required
          by law, and without terminating this Agreement or the lease created
          hereby.

          FPC may declare immediately due and payable all the remaining
          installments of the license fee for the remainder of the term hereof
          of the applicable Exhibit A and such amount, less the fair licensable
          value of the IFN Fibers for the remainder of the terra, shall be
          construed as liquidated damages and shall constitute a debt provable
          in bankruptcy or receivership. In computing such liquidated damages,
          there shall be added to such deficiency the reasonable expenses as FPC
          may incur in connection with relicensing the IFN Fibers. The failure
          of FPC to relicense the IFN Fibers or any part thereof after
          recovering of possession shall not release or affect IFN's liability
          for damages. FPC shall in no event be liable in any way whatsoever for
          failure to relicense the IFN Fibers, on in the event that the IFN
          Fibers is relicensed, for failure to collect the license fee under
          such relicensing.

     B.   Upon the occurrence of an Event of Default by FPC, IFN shall be
          entitled to terminate this Agreement by written notice to FPC, and
          recover any prepaid amounts.

     C.   The right to terminate this Agreement shall be in addition to, and not
          in substitution for, any other rights that a party may have as a
          result of an Event of Default by the other party. In the exercise of
          its right of termination as herein provided, FPC may, at its option,
          elect to terminate this Agreement in its entirety or with respect to
          the particular IFN Fibers to which IFN may be in default of its
          obligations under this Agreement

13.  Remedies. FPC and IFN may sue from time to time to recover any amounts due
     --------                                                                  
          or enforce any rights under this Agreement, and no suit or recovery
          shall bar any subsequent action brought for any amount not theretofore
          reduced to judgment in favor of FPC or IFN as the case may be. Except
          as otherwise provided by law, no repossession of the IFN Fibers by FPC
          shall be construed as an election by FPC to terminate this Agreement
          unless a written notice of such intention is given by FPC to IFN and
          no receipt of moneys by FPC from IFN shall reinstate this Agreement or
          IFN right of possession. All remedies provided in this Agreement are
          cumulative and exclusive and are in addition to any remedies available
          at law or in equity. All remedies may be exercised and enforced
          concurrently or sequentially as often as occasion therefore may arise.

 14. Indemnification and Insurance.
     ----------------------------- 

     A.   IFN shall indemnify and save FPC and its agents, contractors,
          successors and assigns harmless from and against, and shall reimburse
          FPC for all liabilities, obligations, damages, fines, penalties,
          claims, demands, costs, judgments and expenses, including but not
          limited to reasonable attorneys' fees, which may be imposed upon or
          incurred or paid by or asserted against FPC by reason or in connection
          with any negligent act or omission by IFN or any of its agents or
          employees or any failure by IFN to perform or comply with any of the
          provisions of this Agreement

          IFN shall further require as a condition precedent to the sublease or
          assignment of IFN Fibers to others that all such others agree to
          indemnify and save FPC harmless through incorporation of the
          provisions of Section 14A into its respective agreements for sublease
          or assignment of IFN Fibers to such others.

     B.   FPC shall indemnify and save IFN and its AGENTS, contractors,
          successors and assigns harmless from and against, and shall reimburse
          IFN for all liabilities, obligations, damages, fines, penalties,
          claims, demands, costs, judgments and expenses, including but not
          limited to reasonable attorneys' fees, which may be imposed upon or
          incurred by or asserted against IFN by reason of or in connection with
          any negligent act or omission by FPC or any of its agents or employees
          or any failure by FPC to perform or comply with any of the provisions
          of this Agreement

     C.   The party entitled to indemnification hereunder (the Indemnified
          Party) shall notify the other party hereto (the Indemnifying Party) in
          writing of the liability, obligation, damage, fine, penalty, claim,
          demand, cost judgment or expense for which such indemnity allegedly
          applies. The Indemnifying Party may undertake the defense of any such
          claim or action and permit the Indemnified Party to participate
          therein at the Indemnified Party's

          own expense. The settlement of any such claim or action by an
          Indemnified Party without the Indemnifying Party's prior written
          consent which consent shall not be unreasonably withheld or delayed
          shall release the Indemnifying Party from its obligations hereunder
          with respect to such claim or action so settled.

     D.   Notwithstanding any other provision of this Agreement, neither party
          hereto shall be liable to the other for any special, indirect or
          consequential damages or lost profits to anyone arising out of this
          Agreement or the performance or nonperformance of any activity

          The parties shall furnish proof of insurance coverage to each other
          upon request, however, this requirement shall not preclude either
          party from maintaining any required insurance coverage in whole or in

     information as shall be reasonably necessary to permit performance of
     their respective obligations hereunder. Each party hereto shall, in
     accordance with the provisions of this Section, at or prior to the time of
     providing information, identify in writing as confidential all Confidential
     Information. No information which is provided by either party to the other
     shall be considered Confidential Information unless it is specifically so
     identified at or before the time it is provided to such other party.
     Neither party hereto will, without the prior written consent of the party
     providing such Confidential Information,

          l.   use any portion of such Confidential Information for any purpose
               other than performance pursuant to this Agreement, or

          2.   disclose any portion of such Confidential Information to any

               Information (if officers or employees).

     Confidential Information shall remain the property of the disclosing party
     and shall be returned to the disclosing party or shall be destroyed upon
     termination of the performance pursuant to this Agreement on the basis of
     which such Confidential Information was provided. Each recipient party
     agrees to safeguard Confidential Information utilizing the same degree of
     care utilized by such recipient party in protecting its own Confidential
     Information. If the receiving party is compelled to disclose Confidential
     Information through lawful process in judicial or administrative
     proceeding, the receiving party shall give notice within a reasonable time
     to permit the disclosing party the opportunity to seek suitable protective
     arrangements before the Confidential Information is disclosed, and the
     receiving party shall cooperate fully with the disclosing party's efforts
     to obtain such protective arrangements. Confidential Information shall not
     apply to information which

     performance of the obligations set forth in this Agreement other than
     obligations to pay money, shall be suspended or excused in the event that
     such performance is adversely affected by an event of Force Majeure or its
     adverse effects. Force Majeure shall mean the occurrence of any act or
     event that has an adverse effect on the engineering, design, acquisition,
     construction, installation, operation or maintenance of all or any portion
     of the Cable, the IFN Fibers or the FPC Fibers, if such act or event is
     beyond the reasonable control of the party relying thereon as justification

          result of wanton or willful action or Inaction of the party relying
          thereon; provided however, the contesting in good faith by such party
          of any such order or judgment, or the good faith failure by such party
          to contest any such order or judgment, shall not constitute or be
          construed to constitute a wanton or WILLFUL action or inaction of such
          party;

     D.   The adoption of or change after the date of the execution of this
          Agreement in any federal, state, or local laws, rules, regulations,

          party relying thereon to obtain reasonable substitute performance
          within a reasonable time, provided, that in any case where such
          subcontractor or supplier is an Affiliate of the party seeking to rely
          upon such failure as an event of Force Majeure, such failure shall be
          deemed an event of Force Majeure only to the extent that such failure
          is itself due to an event of Force Majeure or its adverse effect; or

     F.   A defect in manufactured equipment or manufactured components,
          provided that in any use where such equipment or component was
          manufactured by the party (or an Affiliate of such party) seeking to
          rely upon such defect as an event of Force Majeure, such defect shall
          be deemed an event of Force Majeure only to the extent that the defect
          was caused by an independent event of Force Majeure.

20.  Dispute Resolution Procedure.
     ----------------------------
     A.   In order to dispute any portion of an FPC invoice, IFN shall notify
          FPC in writing of the amount of the disputed charge and the nature of
          the dispute within thirty (30) days of the date of the invoice. The
          undisputed portion of the invoice shall remain due as rendered. FPC
          will then evaluate the dispute within sixty (60) days, and notify IFN
          of its evaluation. If the dispute is resolved in favor of FPC, IFN
          shall pay FPC the disputed amount due within fifteen (15) days of
          receiving notice from FPC. Otherwise, no action will be required.

     B.   Any dispute arising under this Agreement shall be subject to non-
          binding mediation prior to the initiation of judicial proceedings. The
          disputing parties shall attempt in good faith to resolve their dispute
          in accordance with the procedures and timetable established by the
          mediator. If a resolution of the dispute is not reached by the 30th
          day after the appointment of the mediator, or such later date as may
          be agreed to by the parties, the mediator shall promptly provide the
          disputing parties with a written, confidential, nonbinding
          recommendation on resolution of the dispute, including the mediator's
          assessment of the merits of the principal positions being advanced by
          each of the disputing parties. At a time and place specified by the
          mediator after delivery of the foregoing recommendation, the disputing
          parties shall meet in a good faith attempt to resolve the dispute in
          light of the mediator's recommendation. Each disputing party shall be
          represented at the meeting by a person with authority to settle the
          dispute, along with such other persons as each disputing party shall
          deem appropriate. If the disputing parties are unable to resolve the
          dispute at or in connection with the meeting, then; (1) any disputing
          party may commence such judicial proceedings as may be appropriate;
          and (2) the recommendation of the mediator shall have no further force
          or effect, and shall not be admissible for any purpose, in any
          subsequent judicial proceeding. The costs of the time, expenses, and
          other charges of the mediator and of the mediation process shall be
          borne by the parties to the dispute, with each side in a mediated
          matter bearing one-half of such costs. Each party shall bear its own
          costs and attorneys' fees incurred in connection with any mediation
          under this Agreement.

     C.   Unless otherwise agreed in writing or prohibited by applicable law,
          the parties shall continue to provide service, honor all other
          commitments under this Agreement and continue to make payments in
          accordance with this Agreement during the course of any dispute
          resolution and during the pendency of any arbitration proceeding or
          action at law or in equity relating hereto.

     --------------------                                                    
     to the condition that all requisite governmental and regulatory approvals
     of the execution, delivery and performance of this Agreement shall have
     been received. Each party agrees to exert its best commercial efforts to
     obtain all such approvals applicable to its execution, delivery and
     performance of this Agreement as promptly as reasonably practicable and, in
     furtherance thereof, to modify or amend this Agreement in such particulars
     as may be required to obtain such approval; provided that if any such
     required modification or amendment to this Agreement would, in the good
     faith judgment of either party, render the benefit to such party of this
     Agreement as a whole uneconomical in light of the obligations of such party
     under this Agreement as a whole, then FPC and IFN shall negotiate in good
     faith in an effort to restore, insofar as possible, the economic benefits
     of the IFN Fibers to IFN and the economic benefits of the FPC Fibers and
     the license fee hereunder to FPC provided further, that in the event that
     the parties in good faith are unable to agree to terms and conditions which
     in their good faith judgment will reasonably retain or restore the economic
     benefits of the IFN Fibers to IFN and the economic benefits of the FPC
     Fibers and the license fee hereunder to FPC, then this Agreement shall
     terminate, as well as all obligations of the parties hereunder other than
          l.   payment obligations which have accrued prior to such terminations

          2.   indemnity obligations resulting from events which occurred prior
               to such termination, and

          3.   obligations which pursuant to an express provision of this
               Agreement are to survive any termination of this Agreement

     IFN shall furnish to FPC a copy of the Certification issued by the Florida
     Public Service Commission authoring the IFN to provide fiber optic
     telecommunications services through the Cable pursuant to this Agreement.
     Said Certificate shall be attached hereto, and by reference, shall be
     incorporated into this Agreement.

          the prior written consent of the other party; provided, however, that
          either party may assign this Agreement to an Affiliate upon notice to
          the other party. It shall be a condition precedent to any such
          permitted assignment that the assignee shall execute a counterpart of
          this Agreement, thereby becoming a party to this Agreement and
          agreeing to be bound by all of the terms and provisions hereof. In the
          event of an assignment to a third party, consent from the other party
          may not be unreasonably withheld. Not withstanding anything in this
          Agreement, IFN shall have the explicit right to assign this Agreement
          to a financing institution for collateral purposes and FPC shall
          negotiate in good faith a commercially reasonable subordination and an

          hereunder to FPC provided further, that in the event that the
          parties in good faith are unable to agree to terms and conditions
          which in their good faith judgment will reasonably retain or restore
          the economic benefits of the IFN Fibers to IFN and the economic
          benefits of the FPC Fibers to FPC, then this Agreement shall
          terminate, as well as all obligations of the parties hereunder other
          than
          l.   payment obligations which have accrued prior to such termination,

          2.   indemnity obligations resulting from events which occurred prior
               to such termination, and

          3.   obligations which pursuant to an express provision of this
               Agreement are to survive any termination of this Agreement.

          In the event of a termination of this Agreement pursuant to this
          Section, FPC and IFN shall negotiate in good faith, given the
          circumstances existing at the time of termination, for an appropriate
          transition period for the termination.

     G.   Independent Contractors. In all matters pertaining to this Agreement, 
          -----------------------
          the relationship of FPC and IFN shall be that of independent
          contractors, and neither FPC nor IFN shall make any representations or
          warranties that their relationship is other than that of independent
          contractors. This Agreement is not intended to create nor shall it be
          construed to create any partnership, joint venture, employment or
          agency relationship between IFN and FPC and no party hereto shall have
          the power to bind or obligate any other party. No party hereto shall
          be liable for the payment or performance of any DEBTS, obligations, or
          liabilities of the other party, unless expressly assumed in writing
          herein or otherwise. Each party retains full control over the
          employment, direction, compensation and discharge of its employees,
          and will be solely responsible for all compensation of such employees,
          including without limitation social security, withholding and workers
          compensation responsibilities.

     H.   Exercise of Right. No failure or delay on the part of either party
          -----------------                                                     
          hereto in exercising any right power or privilege hereunder and no
          course of dealing between the parties shall operate as a waiver
          thereof nor shall any single or partial exercise of any right, power
          or privilege hereunder preclude any other or further exercise thereof
          or the exercise of any other right, power or privilege.

     I.   Additional Actions and Documents. Each of the parties hereto hereby
          --------------------------------    
          agrees to take or cause to be taken such further actions, to execute,
          acknowledge, deliver and file or cause to be executed, acknowledged,

                    ----------------------      
     on FPL's Network. IFN will utilize the existing system of dispatch and
     escalation already established by FPL. Notification instructions, and
     subsequent updates, will be forwarded to IFN's Network Operations Center
     (NOC). Following notification, IFN will monitor the fiber optic
     transmission equipment and perform as much diagnostics as the equipment's
     remote devices will allow. The repair notification process may require
     reoccurring meetings between operations personnel to increase reliability
     and meet Licensee expectations. IFN shall take any special requirements for
     the FPL operations scheme under advisement and FPL and IFN shall agree as
     to IFN's notification requirements. The requirements shall be acted upon
     with Licensee satisfaction as the paramount concern.

                    --------------------------

     shall provide prompt, courteous, and efficient service to the caller.

          4.5.5     Billing and Collection.  IFN shall bill and collect monthly
                    ----------------------
     from all Licensees all License fees. After the month in which services is
     rendered, IFN shall forward to FPL by wire transfer the aggregate sum of
     such License fees contracted for less IFN's commission as set forth in
     Exhibit "E", attached hereto and incorporated herein. If FPL does not
     receive payment within the twenty (20) days as set forth above, FPL may
     assess a late payment charge in the amount of one and a half (1 1/2)
     percent of the amount due per month calculated on a daily basis or the
     highest amount then permitted by law, whichever is higher. Failure to
     forward such payment to FPL as due shall constitute a default going to the
     essence of this Agreement and FPL, at its discretion, may cancel this
     Agreement in whole or in part.

     account to be uncollectible in part or in its entirety, IFN will deduct
     this uncollectible amount, net of the commission that would have been due
     IFN under Exhibit E of this Agreement, from the then current month FPL
     remittance under Section 4.5.5 above. IFN will be required to take all
     reasonable and customary actions to collect any and all amounts billed to a
     Licensee including and not limited to direct contact and correspondence

A.  Description of Services
- ---------------------------

1.  Interstate Fibernet (IFN) provides transmission transport links between two 
or more IFN Points of Premise which meet at a designated point between IFN and 
the Customer.  Where, IFN is the provider of local interconnect, Local Loop 
Availability numbers are provided.  The following standards apply to both on a 
one-way basis for both DS1, DS3, OC-N and CCS7 services.

B.  Availability:
- ----------------

Availability is measurement of the total time the service is operative when 
measured over a time period of 30 consecutive days. DS3s and DS1s are considered
to be inoperative when there has been a loss of signal, when loop-back tests
confirm the observation of severely errored seconds, or IFN's network monitoring
system detects a bit-error rate of greater than 1X 10-9.

        99.5% error-free seconds.

        Transmission parameter limits, interface combinations, and technical
        specifications applicable to Interstate Carriers for customer
        interconnection at IFN POPs are contained in ANSI T1.403-1989 and 
        T1.404-1989.

C.      When a Credit Allowance Applies
        -------------------------------

        In case of an interruption to any service, allowance for the period of
        interruption, if not due to the negligence of the customer, shall be as
        follows:

C1.     IFN DS1 and DS3 Services
        ------------------------
        No credit shall be allowed for an interruption of less than 30 minutes.
        The Customer shall be credited for an interruption of 30 minutes or more
        at the rate of 1/1440 of the monthly charges for the facility or service
        for each period of 30 minutes or major fraction there of that the
        interruption continues.

        The monthly charges used to determine the credit shall be as follows:

        The monthly charges shall be the total of all the monthly rate element 
        charges associated with the service

C2.     SONET Ring Services
        -------------------
        For service interuption resulting from a failure of the equipment where
        IFN's system does not automatically self-heal around the point of
        failure, credit shall be allowed only for an interruption of 30 minutes
        or more. The credit will begin when the customer reports the
        interruption to IFN. This credit shall be at the rate of 1/1440 of the
        total monthly charges assessed for that portion of the service that is
        interrupted for each period of 30 minutes or major fraction hereof that
        the interruption continues.

C3.     Credit allowances will not apply if service is interrupted during
        customer requested upgrades and/or additions to IFN service or during
        customer requested rearrangements.

C4.     CCS7 and Enhanced Services
        --------------------------
        For IFN's CCS7 Services, no credit shall be allowed for an interruption
        of less than 30 seconds. The customer shall be credited for an
        interruption of 30 seconds or more as follows:

        For two-point services, when monthly rates are applicable, the credit
        shall be at the rate of 1/8640 of the monthly charges for the service
        for each period of 5 minutes or major fraction thereof that the
        interruption continues.

D.   Other Information and Conditions:
     --------------------------------

D1.  SONET Timing Issues
     -------------------
     DS1's carried over Synchronous Optical Network (SONET) transport systems
     can incur phase transients as a result of pointer adjustments. In some
     instances timing problems could surface in customer's equipment with
     Stratum 3 or better clocks. This may result in the customer's clock
     disqualifying its synchronization reference, generating an alarm and/or
     selecting an alternate reference or entering holdover. To insure proper
     operation, channelized DS1 circuits must comply with Bellcore Technical
     Advisory, TA-NWT-000436. Digital Synchronization Network Plan, and ANSI
     T1.101-1994. When timing is taken from a Company transported DS1, the
     customer's equipment must be capable of accommodating SONET pointer
     adjustments.

D2.  Automatic Protection Switching
     ------------------------------
     The Automatic Protection Switching provides protection on a 1XN basis
     against failure of the electronic facilities between two IFN POPs.
     Protection is furnished through the use of a switching arrangement that
     automatically switches to a spare system when a working system fails. On
     self-healing SONET rings a switch to protect facilities may, in some cases,
     cause IFN services to be routed to an alternate path.

D3.  Performance of Error Free Seconds
     ---------------------------------
     Performance is noted as Error Free Seconds (EFS) which is measured as the
     percentage of seconds over a 24 hour period not containing errors. EFS is
     measured using our network management system which conforms to the CCITT
     Recommendation 0.151.


E.   Trouble Reporting/Monitoring
     ----------------------------
     IFN monitors the network on a 7X24 basis, trouble resolution and repair
     efforts will begin when network surveillance and internal monitoring
     detects errors. Customer may also notify IFN of performance issues and test
     with IFN to isolate and resolve the trouble.
     
     In the event the Customer determines the services provided are not
     conforming with the Technical Standards, the Customer shall provide IFN
     immediate Telephone Notification, via the trouble reporting processes in
     the IFN Operations Manual.

                                  Standards and Objective Policy

A. Description of Services
- --------------------------

1. Interstate Fibernet (IFN) provides transmission transport links between two
or more IFN Points of Premise which meet at a designated point between IFN and
the Customer. Where IFN is the provider of local interconnect, Local Loop
Availability numbers are provided. The following standards apply to both on a
one-way basis for both DS1, DS3, OC-N and CCS7 services.


B. Availability:
- ----------------

Availability is measurement of the total time the service is operative when 
measured over a time period of 30 consecutive days. DS3s and DS1s are considered
to be inoperative when there has been a loss of signal, when loop-back tests 
confirm the observation of severely errored seconds, or IFN's network monitoring
system detects a bit-error rate of greater than 1 X 10-9.

B1.        DS3 and DS1 Performance Objectives
           ----------------------------------

           The performance objectives for IFN DS3 service are as follows:
     a).   Meet or exceed 99.99% percent Circuit Availability on a monthly 
           basis. This objective applies except where a customer's equipment
           is disconnected and/or inoperative or force majeure (i.e. cable
           cuts) or planned maintenance actions initiated by the customer.
     b).   Meet or exceed 99.95% percent Error Free Seconds on a monthly basis.
     c).   Does not exceed .009% percent Severely Errored Seconds on a monthly
           basis.
     d).   Service Continuity - in the event of primary facility failure,
           service is guaranteed to switch to an alternate facility in sixty
           seconds or less. Failure to meet this guarantee will result in a
           credit as described in the following where the trouble is in the
           network on public/private right-of-way.
     e).   Where IFN is responsible for end to end circuit engineering and
           provisioning the end to end Circuit Availability percentage is
           99.88%.

           The performance objectives for IFN DS1 service are as follows:
     a).   Meet or exceed 99.925% percent Circuit Availability on a monthly 
           basis. This objective applies except where a customer's equipment is
           disconnected and/or inoperative or force majeure (i.e. cable cuts)
           or planned maintenance actions initiated by the customer.
     b).   Meet or exceed 99.875% percent Error Free Seconds on a monthly basis.
     c).   Does not exceed .009% percent Severely Errored Seconds on a monthly 
           basis.
     d).   Where IFN is responsible for end to end circuit engineering and 
           provisioning the end to end Circuit Availability percentage is 99.7%.

C.   When a Credit Allowance Applies
     -------------------------------

     In case of an interruption to any service, allowance for the period of
     interruption, if not due to the negligence of the customer, shall be as
     follows:

C1.  IFN DS1 and DS3 Services
     ------------------------
     No credit shall be allowed for an interruption of less than 30 minutes. The
     customer shall be credited for an interruption of 30 minutes or more at the
     rate of 1/1440 of the monthly charges for the facility or servicee for each
     period of 30 minutes or major fraction thereof that the interruption
     continues.

     The monthly charges used to determine the credit shall be as follows:
   
     The monthly charges shall be the total of all the monthly rate element 
     charges associated with the service.

C2.  SONET Ring Services
     -------------------
     For service interruptions resulting from a failure of the equipment where
     IFN's system does not automatically self-heal around the point of failure,
     credit shall be allowed only for an interruption of 30 minutes or more. The
     credit will begin when the customer reports the interruption to IFN. This
     credit shall be at the rate of 1/1440 of the total monthly charges accrued
     for that portion of the service that is interrupted for each period of 30
     minutes or major fraction hereof that the interruption continues.

C3.  Credit allowances will not apply if service is interrupted during customer
     requested upgrades and/or additions to IFN service or during customer
     requested rearrangements.

C4.  CCS7 and Enhanced Services
     --------------------------
     For IFN's CCS7 Service, no credit shall be allowed for an interruption of
     less then 30 seconds. The customer shall be credited for an interruption of
     30 seconds or more as follows:

     For two-point services, when monthly rates are applicable, the credit shall
     be at the rate of 1/8640 of the monthly charges for the service for each
     period of 5 minutes or major fraction thereof that the interruption
     continues.

D.      Other Information and Conditions:
        --------------------------------

D1.     SONET Timing Issues
        -------------------
        DS1's carried over Synchronous Optical Network (SONET) transport systems
        can incur phase transients as a result of pointer adjustments. In some
        instances timing problems could surface in customer's equipment with
        Stratum 3 or better clocks. This may result in the customer's clock
        disqualifying its synchronization reference generating an alarm and/or
        selecting an alternate reference or entering holdover. To insure proper
        operation, channelized DS1 circuits must comply with Bellcore Technical
        Advisory. TA-NWT-000436, Digital Synchronization Network plan, and ANSI
        T1.101-1994. When timing is taken from a Company transported DS1, the
        customer's equipment must be capable of accommodating SONET pointer
        adjustments.

D2.     Automatic Protection Switching
        ------------------------------
        The Automatic Protection Switching provides protection on a 1xN basis
        against failure of the electronic facilities between two IFN POPs.
        Protection is furnished through the use of a switching arrangement that
        automatically switches to a spare system when a working system fails. On
        self-healing SONET rings a switch to protect facilities may, in some
        cases, cause IPN services to be routed to an alternate path.

D3.     Performance of Error Free Seconds
        ---------------------------------
        Performance is noted is Error Free Seconds (EFS) which is measured as
        the percentage of seconds over a 24 hour period not containing errors.
        EFS is measured using our network management system which conforms to
        the CCITT Recommendation 0.151.

E.      Trouble Reporting/Monitoring
        ----------------------------
        IFN monitors the network on a 7X24 basis, trouble resolution and repair
        efforts will begin when network surveillance and internal monitoring
        detects errors. Customer may also notify IFN of performance issues and
        test with IFN to isolate and resolve the trouble.

        In the event the Customer determines the services provided are not

                                   EXHIBIT D




NETWORK MONITORING:
- -------------------

The IFN Network Operations Center (NOC) is manned by highly qualified
technicians on a 7X24 hour basis 365 days a year. Our NOC technicians have
received formal training on the equipment they operate and maintain. The NOC
utilizes a state of the art Digital Facility Management Systems (DFMS) developed
by PRISM/NorTel for general alarm surveillance. DFMS can be used to monitor
complex, hierarchical transport networks, comprising multiple syschronous
optical network (SONET) rates, asynchronous fiber optic transmission (FOTS), and
copper DS3, DS1 transport facilities, plus environmental and security alarms.
DFMS is fully capable of monitoring a variety of telemetry formats including
discrete, TBOS,E2A, ASCII and TLI. DFMS has many features that are used to
monitor, isolate and maintain a fiber system. Alarm correlation can be used to
find a "root cause" of a problem on a fiber system. Additionally, DFMS provides
a number of management features such as alarm prioritization, trouble ticket
management, a graphical network map display, a real-time sectionalization
display, and audible alerting. The DFMS system that IFN currently utilizes has
unlimited growth and expansion potential. We presently actively monitor SONET
fiber systems across a six state area and we are using only a fraction of the
scaleable architecture that is available to us through this system. Any and all
alarms on the network are received in the NOC. The alarms are sent via alarm
sending devices or collections units form each
<PAGE>
 
by the NOC technician and contact with the appropriate maintenance personnel is 
initiated. The NOC coordinates all repair activity and assists the maintenance 
personnel as needed. The NOC keeps management informed on a 30 minute 
recurring basis on any service affecting activity. Upon resolution of the alarm
condition, the NOC technical will complete the IFN Trouble/Alarm Report. 
Management will then be notified of the final resolution. Additionally, the NOC 
coordinates all non-service affecting maintenance with the applicable 
maintenance organization and provides advance service advisories to our
customers so that they in turn can notify their customer base.

                                  ADDENDUM TO
            FIBER OPTIC CAPACITY MARKETING AND OPERATING AGREEMENT


     THIS ADDENDUM TO FIBER OPTIC CAPACITY MARKETING AND OPERATING AGREEMENT, 
for good and valuable consideration, is made this 10th day of July, 1997, by and
between Florida Power & Light Company ("FPL") and Interstate FiberNet or its 
Assign ("IFN").

     1.   This Addendum is intended to confirm and ratify the terms of that 
certain Fiber Optic Capacity Marketing and Operating Agreement entered into 
between the parties and dated March 21, 1996 ("Agreement"), except as 
specifically modified herein.

     2.   Paragraph 4.5.5,  Billing and Collection, of that Agreement shall be 
                            ----------------------
deleted and replace by the following paragraph:

4.5.5  Billing and Collection  IFN shall bill and collect monthly from all 
       ----------------------
Licensees all License fees.  Payments will be due on the 20th day of the month 
in which service is provided, and IFN shall forward to FPL by wire transfer the 
aggregate sum of such License fees contracted for less IFN's commission as set 
forth in Exhibit "E", attached hereto and incorporated herein.  If service is 
initiated prior to the 20th day of the first month of service, then the first 
payment shall be due on the 20th day of the month following acceptance of 
service and shall include payment for the partial initial month and the next
month's charges.  If service is initiated on or after the 20th day of the first 
month of service, then the first payment shall be due on the 20th day of the 
second month following acceptance of service and shall include payment for the 
partial initial month and the next two month's charges.  If FPL does not receive
payment within one month of the due date, then FPL may assess a late payment 
charge of one and a half (1 1/2) percent of the amount due per month calculated 
on a daily basis or the highest amount then permitted by law, whichever is 
higher.  Failure to forward such payment to FPL as due and after notice of such 
nonpayment by FPL to IFN and after a 15 day cure period shall constitute a 
default going to the essence of this Agreement and FPL, at its discretion, may
cancel this Agreement in whole or in part.

     3.   Exhibit E, Commission Schedule, of that Agreement shall be amended by 
deleting the existing Exhibit E and replacing such Exhibit E with the Exhibit E 
attached hereto and incorporated herein.

     4.   Except as this Addendum has amended and changed the Fiber Optic 
Capacity Marketing and Operating Agreement, the terms, conditions and provisions
of that Agreement shall remain in full force and effect.

          (b)  A date for commencement of Service shall be requested by MCI in

               the other party.

     3.   INITIAL TERM AND EXTENSION; APPLICABILITY OF AGREEMENT TO EXISTING
          CAPACITY

                                       3
<PAGE>
 
          (a)  This Agreement shall have an initial term of five (5) years
               beginning on the Effective Date (the "INITIAL TERM"). Thereafter,
               this Agreement shall automatically renew on a month to month
               basis unless terminated by either party upon written notice given
               to the other party not less than thirty (30) days prior to the
               termination date specified in such notice. If this Agreement is
               so terminated, MCI shall be precluded from placing any further
               Service Orders hereunder. However, it is the intention of the
               parties that, notwithstanding any such termination, this
               Agreement shall remain in full force and effect, and shall
               continue to govern, with respect to any then-existing Service
               Order for so long as such Service Order is in effect.

          (b)  Each Service Order shall set its own initial term or, if
               applicable, any extension period thereof, which initial term
               shall in no event be shorter than the applicable minimum term
               specified in Section V of Exhibit D. For ease of administration,
                                         ---------
               orders for different types of Service will be placed on separate
               Service Orders (i.e., DS-ls and DS-3s will not be ordered on the
               same Service Order). Absent a specified extension period, a
               Service Order shall automatically continue in effect on a month-
               to-month basis at the then existing monthly rate unless
               terminated by either party upon written notice given to the other
               party not less than thirty (30) days prior to the termination
               date specified in such notice.

          (c)  This Agreement supersedes and replaces in its entirety the
               Original Agreement. The provision of Existing Capacity by LESSOR
               to MCI shall, as of the Effective Date hereof, be governed by the
               terms and conditions of this Agreement.


     4.   ACCEPTANCE TESTING.

          (a)  LESSOR shall notify the appropriate MCI field coordination
               contact by facsimile, electronic mail or telephone (at the
               numbers specified on the applicable Service Order) that the
               Service is ready for testing, the place where the test/retest
               will take place and the date and time of testing or retesting of
               the Service, which date and time shall be not less than two
               business days after notification. LESSOR shall perform such
               testing pursuant to the Technical Specifications which are
               attached hereto as Exhibit B. Any testing or retesting and
                                  ---------                              
               acceptance thereunder shall require completion of a Service
               Acceptance Form in the form attached hereto as Exhibit A-I and
                                                              -----------    
               shall be performed in accordance with this Article 4, paragraph
               (a). LESSOR shall deliver a completed copy of the Service
               Acceptance Form and a copy of all test results to the MCI field
               representative present at the testing or, if the MCI field
               representative is not present, LESSOR shall deliver same by
               overnight delivery service, facsimile or electronic mail to the
               MCI field coordination contact identified in the Service Order.

                                       4
<PAGE>
 
          (b)  If the testing results meet the Technical Specifications and the
               circuit conforms with the Service Order, the MCI field
               representative shall verify Service acceptance by signing the
               applicable Service Acceptance Form. In the event an MCI
               representative was not present at the testing, MCI shall execute
               the Service Acceptance Form and provide a copy to LESSOR within
               ten (10) days after receipt of the completed form and test
               results. If MCI believes that the test results do not meet the
               Technical Specifications, the MCI field representative present at
               the testing shall so notify LESSOR's representatives, or if no
               MCI representative is present, MCI shall so notify LESSOR within
               ten (10) days after receipt of the completed form and test
               results, in either event specifying the inadequacy in the test
               results. Notwithstanding anything to the contrary contained
               herein, if MCI does not verify Service acceptance in writing (by
               executing a Service Acceptance Form and providing a copy to
               LESSOR) or notify LESSOR of its rejection of the test results
               within said ten (10) day period, MCI shall be deemed to have
               rejected the test results and billing shall not commence. In such
               event, LESSOR shall notify MCI in writing that no Service
               Acceptance Form or other notice was received and shall request
               that MCI notify LESSOR as to the reasons for MCI's rejection of
               the test results. if no such notification is received by LESSOR
               within ten (10) days after receipt by MCI of LESSOR's notice,
               MCI's approval, completion and delivery of the Service Acceptance
               Form shall be deemed to have occurred, and the Commencement Date
               indicated in such Service Acceptance Form for purposes of Article
               2, paragraph (b) hereof shall be deemed to be the date which is
               ten (10) days after receipt by MCI of LESSOR's notice.

          (c)  Service shall be available and billing shall commence on the
               Commencement Date, except as delayed pursuant to Article 2,
               paragraph (c) above. LESSOR shall attach a copy of the fully-
               executed Service Acceptance Form to the first invoice for each
               applicable Service Order. LESSOR shall also provide a copy of the
               fully-executed Service Acceptance Form (by facsimile) to the MCI
               representative placing the order for Service as indicated on each
               Service Order.

          (d)  if LESSOR's test results fail to meet the applicable Technical
               Specification or if MCI notifies LESSOR, in accordance with
               Article 4, paragraph (b) above, that the test results fail to
               meet the applicable Technical Specification, LESSOR shall
               exercise reasonable diligence to cure all Service defects within
               a maximum of ten (10) days ("ACCEPTANCE CURE PERIOD"). If, after
               two (2) Service acceptance retests, LESSOR's Service does not
               meet the applicable Technical Specification, MCI may either: (1)
               cancel the respective Service Order without any further liability
               to LESSOR under the Service Order; or (2) accept an amended
               Technical Specification. If MCI elects to cancel such Service
               Order, MCI shall provide written notice to LESSOR of such intent
               to cancel and shall remove any traffic or test signal within ten
               (10) days after the applicable Acceptance Cure Period. if MCI
               elects to accept the amended Technical

                                       5
<PAGE>
 
               Specification, the Technical Specification for that particular
               Service shall be amended to reflect the actual test results for
               such Service.

          (e)  If MCI does not place traffic or a test signal on the System at
               the time of Service acceptance, LESSOR shall have the right,
               after notifying MCI, to install on the System any device
               necessary to prevent framing errors, false alarming, or other
               transmission impairments resulting from the absence of MCI's
               traffic. Placement of such a device shall not in any way affect
               or delay billing as stated in each Service Order. All MCI circuit
               interconnect, turn-up and/or traffic commencement after the
               Commencement Date must be reported to LESSOR at least one (1)
               business day prior to the loading of traffic onto the System. MCI
               acknowledges that failure to report and arrange for late turn-up
               prior to traffic loading will result in a lack of circuit
               continuity.

     5.   PAYMENT.

          (a)  MCI agrees to pay LESSOR an aggregate monthly Service charge as
               specified on the Service Order(s), subject to and commensurate
               with the terms of Exhibit D. MCI's obligation to pay such monthly
                                 ---------  
               Service charge shall begin on the Commencement Date of the
               applicable Service Order, which is the date of Service acceptance
               as indicated on the Service Acceptance Form. LESSOR shall attach
               a copy of the fully-executed Service Acceptance Form to the first
               invoice for each applicable Service Order. MCI shall be invoiced
               every thirty (30) days in advance of that particular month's
               Service (e.g., January 1st invoice for month of January);
               provided, however, that the first invoice shall cover the period
               from the Commencement Date through the end of the next month
               (e.g., April 16 through May 31). MCI shall pay LESSOR's invoice
               within thirty (30) days of receipt (the "INVOICE DUE DATE"). Any
               amount which is not paid in full by the invoice due date shall be
               subject to a late payment charge (the "LATE PAYMENT CHARGE")
               calculated from the invoice due date to the date LESSOR receives
               MCI's regular invoice payment. The late payment charge shall be
               calculated by multiplying any portion of the invoice which
               remains' unpaid after the invoice due date by the prime interest
               rate quoted by The Wall Street Journal on the invoice due date, 
                              ----------------------- 
               plus three percentage (3%) points, prorated monthly, on a thirty
               (30) day basis (the "PENALTY RATE"). LESSOR shall invoice MCI for
               the late payment charge on the next regular monthly invoice.

          (b)  Notwithstanding the provisions of Article 5, paragraph (a) above,
               MCI shall have the right to reasonably dispute any invoice amount
               that MCI believes is incorrect (the "DISPUTED AMOUNT"). In the
               event of a Disputed Amount, MCI shall nevertheless pay to LESSOR,
               within the time frame set forth herein, the undisputed amount, if
               any, due and owing to LESSOR and provide to LESSOR, in writing'
               the grounds upon which MCI is contesting the Disputed Amount. MCI
               shall not be required to pay the Disputed Amount until such

                                       6
<PAGE>
 
               dispute is resolved in accordance with Article 23. If the matter
               is later resolved against MCI, MCI shall pay the Penalty Rate on
               the applicable portion of the Disputed Amount from the first date
               of dispute until the date of resolution, which in no event shall
               exceed the conclusion of an Article 23 proceeding.

          (c)  Notwithstanding the provisions of Article 5, paragraph (a) above,
               MCI shall not be responsible to pay any LESSOR charge not
               invoiced to MCI within ninety (90) days after such LESSOR charge
               originated. For purposes of this subparagraph (c), a recurring
               monthly Service charge shall be deemed to originate on the first
               day of the month (e.g., recurring charges for the month of
               January shall be deemed to originate on January 1). By way of
               example, MCI will not be obligated to pay a recurring monthly
               Service charge for the month of January if that charge is not
               invoiced to MCI on or before that date which is ninety (90) days
               after January 1.

     6.   ADDITIONAL CHARGES.
     
          (a) (i)   MCI shall pay gross receipts, right-of-way, franchise, or
                    sales or use taxes, or other similar charges that are levied
                    upon LESSOR or legally required to be collected by LESSOR as
                    a direct result of LESSOR's provision of services to MCI
                    hereunder, but in no event shall MCI be obligated to pay
                    income taxes levied upon LESSOR's net income or any real or
                    personal property taxes assessed against. LESSOR or LESSOR's
                    property.

             (ii)   MCI shall have the right to protest or appeal any such tax
                    or charge assessed by any taxing authority, either directly
                    or indirectly, as well as present any applicable exemption
                    certificates.

          (b)  MCI shall not be obligated to pay any additional charges other
               than those contemplated by this Agreement; provided, however, MCI
               may pay direct verifiable one time charges (e.g., installation,
               service, etc.) where such charges are negotiated, and appear upon
               the face of a fully-executed Service Order. Where applicable and
               approved, such charges shall appear in LESSOR's first invoice to
               MCI.

     7.   INTERRUPTION/CREDITS. LESSOR represents and warrants that LESSOR will
          provide and maintain the System during the term of this Agreement in
          full compliance with the applicable technical Specification.

          (a)  MCI shall be entitled to a credit as set forth in paragraph (b)
               of this Article 7 for periods in which the LESSOR falls to
               operate the System in accordance with the Technical
               Specification. LESSOR agrees to undertake immediate action to

                                       7
<PAGE>
 
               correct any Interruption to the System within two (2) hours after
               receiving notice from MCI that an Interrupted condition exists.

          (b)  MCI shall not be entitled to a credit for a Non-Catastrophic
               Interruption of Service that is less than thirty (30) minutes in
               duration. The amount of the credit owed to MCI for a Non-
               Catastrophic Interruption of Service thirty (30) minutes or
               longer shall be equal to 1/1440 of the monthly rate of charges
               applicable to that portion of the System which is subject to the
               Interruption multiplied by each one-half (1/2) hour or major
               fraction thereof of the length of the Interruption. If more than
               one Non-Catastrophic Interruption of Service occurs within a
               twenty-four (24) hour period, the length of all such
               Interruptions shall be aggregated and treated as a single
               Interruption for purposes of determining the availability and
               amount of a credit. Interruptions shall be measured from the time
               that the Interruption starts to the time of restoration. MCI may
               notify LESSOR of Interruptions by telephone, facsimile,
               electronic mall, courier or any such similar expedited notice
               mechanism. In order to facilitate such notice, an "ESCALATION
               LIST" of appropriate contact personnel of LESSOR and MCI is
               attached hereto as Exhibit C.
                                  --------- 

          (c)  When Service provided by LESSOR includes more than one
               communications path, the Interruption allowance applies only to
               the path Interrupted.

          (d)  An Interruption, for purposes of this Article 7, shall be reduced
               by the time period during which MCI fails to accord access to any
               necessary MCI facilities provided by LESSOR for the purpose of
               investigating and clearing troubles.

          (e)  In the event of Interruption of local access service or any other
               service provided by parties other than LESSOR (other than service
               provided by a Third Party Provider), LESSOR shall have no
               liability to MCI and MCI shall continue to be liable for all
               payments to LESSOR.

          (f)  In the event of a Non-Catastrophic Interruption of Service on
               more than five (5) days during any thirty (30) day period and so
               long as such Interruption is not caused in whole or in part by M
               MCI's own negligence, MCI shall, at its option, have the right to
               either (i) terminate any Service Order(s) along the affected
               route, or (ii) receive a credit against amounts owing under the
               next invoice received from LESSOR hereunder, which credit shall
               be in an amount equal to the monthly Service charge attributable
               to the affected route as set forth in Article 5, paragraph (a)
               above and in the applicable Service Order(s). The parties agree
               to use LESSOR's maintenance log, if any, for purposes of
               calculating the duration of the Interruption and, if applicable,
               the credit specified in Article 7, paragraph (b). In the absence
               of such a log, MCI shall produce sufficient documentation to
               substantiate its claim.

          (g)  THE FOREGOING WARRANTY AND REMEDIES WITH RESPECT TO INTERRUPTIONS
               OF SERVICE ARE EXCLUSIVE AND IN LIEU OF ALL OTHER SUCH WARRANTIES
               OR REMEDIES, WHETHER EXPRESS, IMPLIED OR STATUTORY. IN THE EVENT
               OF ANY INTERRUPTION IN THE SERVICE WHATSOEVER, NEITHER LESSOR,
               LESSOR's AFFILIATES NOR ANY THIRD PARTY PROVIDER, NOR OPERATOR OF
               FACILITIES EMPLOYED IN THE PROVISION OF THE SERVICE SHALL BE
               LIABLE TO MCI OR THIRD PARTIES FOR ANY DIRECT, INDIRECT,
               CONSEQUENTIAL, SPECIAL, ACTUAL, PUNITIVE OR ANY OTHER DAMAGES, OR
               FOR ANY LOST PROFITS OF ANY KIND OR NATURE WHATSOEVER.

     8.   SYSTEM MAINTENANCE. System maintenance normally will not result in
          Service Interruption. However, in the event System maintenance should
          require the Interruption of Service, to the greatest extent possible
          it shall be carried out only during non-peak hours; provided, however,
          LESSOR shall provide MCI with ten (10) business days' notice prior to
          undertaking any such maintenance activity in accordance with the
          notice procedure specified in Article 7, paragraph (b) above. System
          maintenance requiring interruption of Service shall not be entitled to
          an Article 7 credit and shall be completed as soon as practicable, but
          in no event shall such maintenance exceed two (2) hours.

     9.   INDEMNIFICATION. LESSOR and MCI (hereinafter where either has
          undertaken the action or inaction to be indemnified against shall be
          beknown as the "INDEMNIFYING PARTY") agree to assume all liability for
          and indemnify, defend and hold harmless the other party or any third
          party claiming through the other party, from and against all
          liability, loss, cost, damage, expense or cause of action, of
          whatsoever character, or injury or death of any person and damage to
          or destruction of any property, including, without limitation, third
          parties and all related expenses, including, but not limited to,
          reasonable attorneys' fees, investigators' fees and litigation
          expenses resulting in whole or in part from any of the following:

          (a)  claims for libel, slander, infringement of copyright or
               unauthorized use of a trade secret, trademark, trade name or
               service mark that results from the transmission of material over
               the System by MCI, authorized representatives of MCI or other
               persons not associated with, or related to, either LESSOR or MCI;
               or

          (b)  claims of any person not a party to this Agreement arising out of
               the negligent or willful act or omission of the Indemnifying
               Party or its agents, servants, employees, contractors or
               representatives; or

                                       9
<PAGE>
 
          (c)  claims for patent infringement arising out of the use of the
               System by MCI or any person authorized by MCI and resulting from
               the acts of MCI or MCI's representatives in combining the System
               with the facilities of MCI IC' or others, or using the System in
               connection with those of MCI or others; or

          (d)  claims, except as otherwise set forth herein for the breach of or
               failure to comply with any term or condition of this Agreement by
               the Indemnifying Party or its officers, employees or invitees; or

          (e)  claims resulting from patent or trade secret infringement or
               infringement or unauthorized use of trade secrets or trade name
               by the Indemnifying Party

     10.  DEFAULT/TERMINATION. A party may deliver to the other party a "NOTICE
          OF DEFAULT" for: (i) failing to make any payment owed hereunder, when
          no bona fide dispute exists; (ii) the breaching by either party or its
          agents, assigns or affiliates of any of the terms, conditions,
          covenants, warranties or representations herein; or (iii) the filing
          or initiating of proceedings seeking liquidation reorganization or
          other such relief under any bankruptcy or insolvency law (state or
          federal). A party that has received a Notice of Default shall have
          thirty (30) days to cure the alleged breach (the "CURE PERIOD"),
          provided, however, that either party shall be given ninety (90) days
          to remove any involuntary bankruptcy proceeding. If such party falls
          to cure the breach within the Cure Period, the non-defaulting party
          shall have the right to either (a) suspend its performance or payment
          obligations, (b) terminate the affected Service Order(s), (c)
          terminate this Agreement in its entirety, (d) seek an order of
          specific performance, and/or (e) seek the award of compensatory
          damages.

     11.  CANCELLATION.

          (a)  MCI may for any reason voluntarily (not required by governmental/
               regulatory action) cancel a Service Order prior to the end of the
               initial term as set forth in the Service Order. In the event of a
               voluntary MCI cancellation, MCI shall notify LESSOR, in writing,
               that it desires to cancel the Service Order(s) within thirty (30)
               days (the "SERVICE CANCELLATION NOTICE") and the date upon which
               MCI is to cease being billed for the use of the canceled
               circuit(s). The Service Cancellation Notice shall set forth the
               effective date of cancellation (the "CANCELLATION DATE").

          (b)  If MCI voluntarily cancels a Service Order prior to the end of
               the applicable minimum term for such Service Order as specified
               in Section IV of Exhibit D, MCI shall pay a cancellation fee to
                                ---------    
               LESSOR that is equal to [________________________________________
               _________________________________________________________________
               ___________]. If MCI voluntarily cancels a Service Order after
               the expiration of the applicable minimum term, but prior to the
               end of the initial term as set forth in the Service Order, MCI
               shall pay a cancellation fee to LESSOR that is

                                       10
<PAGE>
 
               equal to [_______________________________________________________
               ____________________________________] (collectively referred to
               as "MCI VOLUNTARY CANCELLATION FEE").

          (c)  The MCI Voluntary Cancellation Fee described in Article 1;
               paragraph (b) above, represents LESSOR's exclusive remedy for a
               voluntary cancellation by MCI and shall be in lieu of any other
               remedies either at law or in equity.

          (d)  Either party shall have the right to cancel this Agreement and
               any related Service Order(s) without liability if LESSOR is
               prohibited from furnishing the Service or if any material rate or
               term contained herein is substantially changed by order of the
               highest court of competent jurisdiction to which the matter is
               appealed, the FCC or other local, state or federal governmental
               authority.

          (e)  Subsequent to the Commencement Date of a Service Order, in lieu
               of terminating the circuit(s) placed in service pursuant to the
               Service Order, MCI may by written notice to LESSOR request that
               said circuit(s) be replaced by new circuit(s) having a
               configuration specified in said notice. LESSOR shall permit such
               circuit substitution without a cancellation fee for the old
               circuit(s) if: a) MCI has requested same at least sixty (60) days
               prior to the requested in service date of the new circuit(s); b)
               the minimum term of the replacement circuit(s) shall be written
               for a period of time at least equal to the remaining minimum term
               of the old circuit(s) and for a monthly Service charge equal to
               or greater than that of the old circuit(s); and c) the requested
               replacement circuit(s) are available on LESSOR's network as
               determined by LESSOR.

     12.  INTERCONNECTION.
     
          (a). Except for the locations identified in Article 12, paragraph (b)
               below, MCI shall pay the cost of Service interconnection from
               LESSOR's point of presence to MCI's point of presence. LESSOR
               shall coordinate with MCI for interconnection completion,
               including establishing any applicable points of demarcation,
               entrance facilities, interconnection facilities and equipment
               access. The parties shall work together to keep such costs to a
               minimum.

          (b). [________________________________________________________________

     13.  LAWS AND LICENSES. This Agreement is subject to all applicable
          federal, state and local laws, regulations, rulings and orders of
          governmental agencies, including, but not limited to, The
          Communications Act of 1934, and the rules and regulations of the FCC
          and is contingent upon LESSOR's obtaining and continuing any required
          approval

                                       11
<PAGE>
 
          or authorization of the FCC or any other duly authorized governmental
          body LESSOR shall work with MCI to acquire any permits or licenses
          required to be obtained by MCI. LESSOR and MCI agree that the statute
          of limitations set forth in The Communications Act of 1934, 47 U.S.C.
          section 415, as amended, shall govern all actions arising out of this
          Agreement, including arbitrations.

     14.  NOTICE. Except for the notice provisions related to Article 7,
          paragraph (b), all notices, requests, demands or other communications
          provided for, permitted or required by this Agreement shall be
          delivered by registered or certified mall, return receipt requested,
          or by commercial overnight delivery service, or by facsimile, and
          shall be deemed given (a) when received or when delivery is refused,

          the case of notices sent by U.S. mall or by overnight delivery
          service), or (b) on the next day after the notice was sent (in the
          case of notices sent via facsimile). Notwithstanding the foregoing,
          the original of any facsimile notice must be sent by overnight
          delivery service in order for the delivery of such notice to be deemed
          effected. Notices shall be addressed as follows:

     15.  ASSIGNMENT. The capacity leased to MCI hereunder may be used by MCI
          for any purpose in the normal course of its telecommunications
          business. LESSOR recognizes that MCI sells its telecommunications
          services to customers both pursuant

                                       12
<PAGE>
 
          to tariff and pursuant to customer contracts, that some of MCI's
          customers are "RESELLERS" of telecommunications services and the
          capacity leased to MCI hereunder could be utilized to provide such
          services to MCI's customers, including such resellers. LESSOR
          acknowledges that MCI has entered into this Agreement in reliance upon
          the technical and financial capabilities and experience of LESSOR.
          Therefore, LESSOR shall not sell, assign, or transfer (the "TRANSFER")
          a) a majority ownership interest in LESSOR or any portions of LESSOR's
          transmission network providing service to MCI or b) responsibility for
          the operation of LESSOR's transmission network, to any third party
          without the prior written consent of MCI, which consent shall not be
          unreasonably withheld, provided, however, that LESSOR may assign all
          of its rights to a subsidiary or affiliate company of LESSOR without
          obtaining MCI's prior consent. LESSOR shall give MCI not less than
          sixty (60) days prior written notice of any Transfer of LESSOR's
          interest hereunder.

     16.  GOVERNING LAW. This Agreement shall be construed and enforced in
          accordance with, and the validity and performance hereof shall be
          governed by, the laws of the State of New York;

     17.  FORCE MAJEURE.

          (a)  Except as provided in paragraphs (b) and (c) below, neither party
               shall be liable for any failure or suspension of performance
               hereunder (including the failure to make payments when due) due
               to acts of God, fire, explosion, local, state or federal
               government action or war (individually, a "FORCE MAJEURE EVENT").
               The party claiming relief under this Article 17 shall exercise
               its best efforts to minimize the time of any failure of or
               suspension of performance hereunder and promptly notify the other
               party of the occurrence of the force majeure event.

          (b)  If such failure of performance shall be on the part of MCI and
               shall be for thirty (30) days or less, then the affected Service
               Order(s) shall remain in effect and MCI shall remain liable for
               all charges thereunder If such failure of performance shall be in
               excess of thirty (30) days, MCI shall have the option to maintain
               the affected Service Order(s) in effect by continuing payments or
               MCI may cancel the Service Order(s) without further liability.

          (c)  If such failure of performance shall be on the part of LESSOR and
               shall be for thirty (30) days or less, then the affected Service
               Order(s) shall remain in effect with no charge to MCI and no
               liability on the part of LESSOR. If LESSOR's failure of
               performance lasts for more than thirty (30) days, then the
               affected Service Order(s) may be canceled by MCI with no
               liability on the part of either party.

     18.  ENTIRE AGREEMENT; MODIFICATION. This Agreement contains the entire
          agreement of the parties pertaining to the subject matter hereof and
          supersedes all prior 

                                       13
<PAGE>
 
          communications and agreements, whether oral or written. No subsequent
          modification of this Agreement shall be effective or binding unless it
          is made in writing and signed by an authorized officer of the party
          against whom enforcement of the modification is sought.

     19.  CONSENTS. Any requested consent to be given by any party to this
          Agreement shall not be unreasonably withheld.

     20.  PROVISION CONFLICTS. In the event of a conflict between the provisions
          of this Agreement and those of any Exhibit or Service Order, unless
          the provisions of the Exhibit or Service Order expressly take
          precedence over the provisions of this Agreement, the provisions of
          this Agreement shall prevail and such Exhibits and Service Orders
          shall be corrected accordingly.

     21.  WAIVER For any waiver of any right, option or privilege under this
          Agreement to be binding, it must be made in writing and signed by the
          party against whom enforcement of the waiver is sought. No waiver of
          the terms of this Agreement shall occur because of a failure by either
          MCI or LESSOR to exercise any option, right or privilege on any
          occasion or through the course of declining, and any waiver granted
          shall not be construed to be a waiver of the same on any other
          occasion unless agreed to in writing and executed by the parties.

     22.  CONFIDENTIALITY OF AGREEMENT. The parties to this Agreement shall
          treat this Agreement, its notices and Exhibits and their terms and
          conditions, as strictly confidential. Neither party shall disclose any
          of this information or any of these materials to any person who is not
          a party to this Agreement. If a court or other governmental agency
          with proper jurisdiction orders a party to disclose or to provide any
          data or any documents relating to this Agreement, that party shall
          immediately notify the other party and undertake all necessary
          measures to protect the other patty's proprietary information and
          trade secrets.

     23.  DISPUTE RESOLUTION. Any dispute arising out of or related to this
          Agreement which cannot be resolved by negotiation shall be settled by
          binding arbitration in accordance with the J.A.M.S./ENDISPUTE
          Arbitration Rules and Procedures ("ENDISPUTE RULES"), as amended by
          this Agreement. The costs of arbitration, including the fees and
          expenses of the arbitrator, shall be shared equally by the parties
          unless the arbitration award provides otherwise. Each party shall bear
          the cost of preparing and presenting its case. The parties agree that
          this provision and the arbitrator's authority to grant relief shall be
          subject to the United States Arbitration Act, 9 U.S.C. 1-16 et seq.
          ("USAA"), the provisions of this Agreement, and the ABAAAA Code of
          Ethics for Arbitrators in Commercial Disputes. The parties agree that
          the arbitrator shall have no power or authority to make awards or
          issue orders of any kind except as expressly permitted by this
          Agreement, and in no event shall the arbitrator have the authority to
          make any award that provides for punitive or exemplary

                                       14
<PAGE>
 
          damages. The arbitrator's decision shall follow the plain meaning of
          relevant documents, and shall be final and binding. The award may be
          confirmed and enforced in any court of competent jurisdiction. All
          post-award proceedings shall be governed by the USAA.

     24.  THIRD PARTY PROVIDERS.

          (a)  The parties acknowledge and agree that certain Services leased by
               MCI hereunder may be delivered on a portion of the System that is
               owned by a Third Party Provider, but is managed by LESSOR as
               agent of the Third Party Provider. The portion(s) of the System
               owned by such Third Party Provider(s) as of the Effective Date,
               and the names of such Third Party Provider(s), are listed on
               Exhibit F attached hereto. Promptly upon entering into any
               ---------                                                 
               additional agency arrangements with Third Party Providers, LESSOR
               shall provide to MCI a revised Exhibit F which shall be attached
                                              ---------                        
               to this Agreement.

          (b)  With respect to each Third Party Provider, LESSOR represents and
               warrants that (i) such Third Party Provider is the lawful owner
               of the applicable portion of the System identified on Exhibit F
                                                                     --------- 
               and has all necessary rights, authority and approvals to provide
               the Service on such portion of the System in accordance with this
               Agreement, (ii) LESSOR is the duly authorized agent of such Third
               Party Provider and has all necessary rights, authority and
               approvals to market and provide the applicable Service to MCI, as
               agent of the Third Party Provider, in accordance with this
               Agreement, (iii) as agent of the Third Party Provider, LESSOR has
               the authority to act on behalf of such Third Party Provider and
               to legally bind such Third Party Provider to the terms and
               conditions of this Agreement, and (iv) by its signature as agent
               on the applicable Service Order, LESSOR shall so bind the Third
               Party Provider.

          (c)  LESSOR assumes all liability for and indemnifies, defends and
               holds MCI harmless from and against any liability, loss, cost,
               damage, expense, claim or cause of action resulting from (i) a
               breach by LESSOR of any of the representations and warranties set
               forth in subparagraph (b) above, (ii) the inaccuracy or
               incorrectness of any of the representations and warranties set
               forth in subparagraph (b) above, or (iii) the inability of LESSOR
               to continue to provide Service in accordance with this Agreement
               (for reasons other than a force majeure event, which shall be
               governed by Article 17 of this Agreement, or an Interruption of
               Service, which shall be governed by Article 7 of this Agreement)
               on a portion of the System owned by a Third Party Provider (e.g.,
               Service can no longer be provided on a Third Party Provider's
               system because of a termination or expiration of LESSOR's agency
               arrangement with the Third Party Provider).

through the Network Control Center's remote surveillance equipment or otherwise.

d.   [_________________], Sprint responsibilities - Sprint maintenance personnel
shall at Sprint's sole option, perform Demand Maintenance of Regenerator
Locations along the Route. IFN has the right to request that Sprint perform
emergency cable restoral service, which service is deemed to be Demand
Maintenance, in the event of [_____] outage. However, this type of service will 
be performed at Sprint's sole discretion. Such restoral shall be limited to the
placement [___________________________________________________________]portion
of the Route for the temporary restoral service to IFN and Sprint fibers.

e.   [___________________], Sprint responsibilities - Sprint maintenance
personnel shall perform Routine and Demand Maintenance and route patrol of the
buried fiber optic cable along the Route. Sprint maintenance personnel shall at
Sprint's sole option, perform Demand Maintenance of Regenerator Locations along
the Route. In addition, Sprint shall perform emergency cable restoral service,
which service is deemed to be Demand Maintenance.

f.   Sprint maintenance personnel shall be available for dispatch twenty-four
(24) hours a day, seven days a week. Sprint shall use reasonable efforts to have
its first maintenance employee at the site requiring Demand Maintenance within
four (4) hours from the time of the alarm identification by Sprint's Network

     Repair/Vendor Escort Record form confirming the location, time, and date of
     the escort service.

     -------------------------
     the activities and operations of its Representative (where applicable) as

                                ---------------

     THIS AGREEMENT is made as of January 31, 1997 between SOUTHERN TELECOM
1, INC., a Delaware corporation ("Southern Telecom"), and INTERSTATE FIBERNET, a
Georgia general partnership ("IFN").

                                   PREMISES
                                   --------

     IFN desires Southern Telecom to construct and lease to IFN a
telecommunications fiber optic facility made up of 12 fiber optic strands and
related equipment to be installed on Alabama Power Company ("APC") electric
transmission facilities and rights of way from APC's Plant Gaston facility in
Alabama to Montgomery, Alabama, and Southern Telecom desires to so construct and
lease such facility.

     Southern Telecom desires to include an additional 12 fiber optic strands
within such fiber optic facility for its potential future use. In the interim,
IFN desires to acquire a revocable license to use such additional 12 fibers and
Southern Telecom desires to grant such revocable license.

     In total, Southern Telecom will construct a 24 fiber optic strand fiber
optic facility, 12 strands of which it will lease to IFN and 12 strands of which
it will grant IFN a revocable right to use and IFN will therefore undertake the
responsibility of acquiring the necessary permits and licenses required for
operating the entire 24 strand fiber optic facility and paying the costs of
maintaining such fiber optic facility.

     Southern Telecom will have the option to lease to IFN any of the additional
12 licensed fibers after the 9th anniversary of the lease, and, to the extent
Southern Telecom does not lease IFN at least 6 of the licensed fibers under its
option, IFN will have the right to lease from Southern Telecom up to a total of
6 of the licensed fibers.

     Accordingly, the parties agree as follows:

12.   LIMITATION OF WARRANTIES, DAMAGES AND CLAIMS

      12.1. WARRANTY FOR SERVICES. In performing hereunder, Southern Telecom
will exercise due care to ensure that its services are performed in a
workmanlike manner and meet the standards and specifications set forth in this
Agreement. Other than the extended service outage credits set forth in Section
4.4, failure to meet these obligations will not subject Southern Telecom, APC or
any other affiliate of the Southern Company to any claims or liabilities other
than, if applicable, to reperform the work. Except as provided in this
Agreement, Southern Telecom makes no warranties and IFN will accept Southern
Telecom's services without further warranty of any nature. The warranties set
forth in this Agreement are the sole and exclusive warranties provided to IFN
hereunder with respect to the service to be performed by Southern Telecom
hereunder, and all other express or implied warranties (including, without
limitation, any warranty of description, merchantability or fitness for a
particular purpose) are hereby disclaimed.

      12.2. LIMITATION OF DAMAGES. Neither Southern Telecom nor its affiliates
will be liable to IFN for any special, indirect or consequential damages or loss

<PAGE>
 
                                                                    CONFIDENTIAL

foregoing, Southern Telecom and its affiliates' maximum total cumulative
liability in connection with this Agreement will not exceed [_____________].

      12.4.  Time To Bring Claims. IFN's failure to bring a claim against
Southern Telecom within six (6) months after the sooner of, the date on which
IFN becomes aware, or should have become aware of the existence of a potential
claim constitutes a waiver of such claim.


13.   IDEMNIFICATION

      13.1.  Indemnification. IFN will indemnify and hold harmless and hereby
             --------------- 
releases Southern Telecom, its affiliates, agents, contractors and subsidiaries
and its and their officers, directors, employees and agents (each an
"Indemnitee") from and against any (1) liability, (2) amounts paid in compromise
or settlement (whether or not liability has been determined or can be known),
(3) loss, (4) penalty, (5) forfeiture or (6) cause of action of any kind or
nature, whether actual or alleged, and any expenses connected therewith
(including, without limitation, litigation expenses, reasonable attorneys' fees
and interest at Southern Telecom's cost of funds rate accruing from the date a
loss or cost or expense is incurred until the date when such indemnification is
satisfied) arising out of or in connection with the following types of claims as
they relate to this Agreement, the transactions contemplated herein or the Fiber
Optic Facility (each a "Claim"):

          13.1.1.  Any claim by IFN or any person using the Fiber Optic Facility
by, under or through IFN, or its or their agents, whether or not such claim
arises from Indemnitee's negligence but excluding any such claim that arises
from the Indemnitee's gross negligence or willful misconduct.

          13.1.2.  Any claim by IFN, any of its affiliates, agents, contractors
or subsidiaries or its or their officers, directors, employees or agents arising
from damage to tangible property or personal injury (including the death of
persons), whether or not such claim arises from Indemnitee's negligence but
excluding any such claim that arises from the Indemnitee's gross negligence or
willful misconduct.

          13.1.3.  Any claim arising from IFN's or any of its customer's failure
to comply with any law, regulation, ordinance, order, injunction, ruling or
award of any government agency or court, whether or not such claim arises from
Indemnitee's negligence but excluding any such claim that arises from the
Indemnitee's gross negligence or willful misconduct.

          13.1.4.  Any claim arising from the failure of IFN to acquire or
maintain any street franchise or public or private right of way or easement
necessary to permit the presence or use of the Fiber Optic Facility, other than
any such claim that arises from the Indemnitee's negligence or willful
misconduct, but an Indemnitee's recovery therefor will be reduced to the extent
of such Indemnitee's own negligence.
                                       12
<PAGE>
 
                                                                    CONFIDENTIAL

          13.1.5.  Any other third-party claim to the extent such claim arises
from the negligence, breach or willful misconduct of IFN, its affiliates,
agents, contractors, customers or subsidiaries or its or their officers,
directors, employees or agents.

    13.2. INSURANCE. At all times during the Term and thereafter until the
          ---------     
resolution or satisfaction of all Claims, IFN will maintain in force and effect
one (1) or more general liability insurance policies providing minimum coverage
(including, without limitation, coverage for liabilities contractually assumed)
of [__________________] per occurrence and in the aggregate for bodily injury,
[__________________] per occurrence for property damage, and excess liability
umbrella coverage of [__________________]. All such policies will contain a
waiver of subrogation in favor of the Southern Company, its affiliates and all
Indemnitees.

      13.3.  SETTLEMENT AND DEFENSE OF CLAIMS.
             ---------------------------------

          13.3.1. Notice of Claim. If any Claim arises for which an Indemnitee
                  ----------------
is or could be liable to a third party under this Agreement, then such
Indemnitee will promptly notify IFN of such Claim and IFN will have thirty (30)
days after receipt of such notice to inform Indemnitee whether IFN or its
insurer (individually or collectively, the "Indemnitor") will assume the
defense of the Claim or not. If Indemnitor assumes the defense of the Claim,
then Indemnitor will employ competent and experienced legal counsel appropriate
for the defense of the Claim in view of the facts and circumstances and pay all
expenses of the defense of such Claim. If Indemnitee is named as a party to any
action in connection with a Claim, then Indemnitee may control its defense of
the Claim at its expense. So long as Indemnitee is not named as a party to such
action and Indemnitor assumes the defense of any such Claim and protects the
assets of Indemnitee from levy, lien or seizure, Indemnitor may control the
conduct of such defense and will not be responsible for any expenses of
Indemnitee in connection with the defense of any such Claim. Indemnitee's
failure to provide timely notice of a Claim will not relieve Indemnitor of its
obligations hereunder except to the extent such failure materially prejudices
Indemnitor.

          13.3.2. Indemnitee's Right To Defend. If Indemnitor does not assume
                  ----------------------------
the defense of a Claim, then Indemnitee may defend such Claim in the manner it
deems appropriate, and settle such Claim on terms it deems appropriate. If a
Claim is not settled, then Indemnitor will satisfy any judgment rendered against
Indemnitee with respect to such Claim.

          13.3.3. Settling Claims. Except as provided in Section 13.3.2,
                  ---------------
Indemnitee may not settle a Claim without Indemnitor's prior written approval.
If Indemnitor disapproves such settlement, then Indemnitor must reimburse
Indemnitee for Indemnitee's reasonable expenses in connection with its control
of the defense of such Claim to the date of such assumption. IFN's failure to
assume such defense and to pay such reimbursement will give Indemnitee the right
to settle such Claim.

                                                                    CONFIDENTIAL

      13.4.  Exclusion from Waiver. The waivers and indemnities in this
             ---------------------
Agreement in favor of Southern Telecom will not apply to damages arising out of
bodily injury to persons or damage to property caused by or resulting from the
sole negligence of Southern Telecom, or its agents or employees to the extent
prohibited by law.


14.   WAIVER OF SUBROGATION

      To the fullest extent permitted by law, Southern Telecom and IFN hereby
waive any claim each may have against the other or any affiliate by way of
subrogation or otherwise from any and all liability for any loss or damage to
property, whether caused by the negligence or fault of the other party, to the
extent such loss or damage is covered or required to be covered by the fire and
extended coverage policy or all-risk policy with respect to the Fiber Optic
Facility. Southern Telecom and IFN will each cause any fire insurance and
extended coverage or all-risk policies which it maintains with respect to the
Fiber Optic Facility to contain a provision whereby the insurer waives any
rights of subrogation against the other party.


15.   FORCE MAJEURE

      The parties' obligations under this Agreement will be suspended as a
result of any act of God, hurricane, tornado, rain, flood, sink hole, wind,
hail, lightning, earthquake, snow or ice, extreme high or low temperatures,
water or gas main break, fire, explosion, riot, terrorist act, military action,
failure to act on the part of a governmental authority, strike, lockout or other
labor problem, transportation delay, unavailability of supplies or materials or
change in or in the interpretation of any law or regulation. Such obligations
will be suspended until such time as the interrupting event abates and the
parties may reasonably operate as they had prior to such event.

Facility unusable for IFN's use, in Southern Telecom's reasonable discretion, is
damaged and such damage can be repaired or the Fiber Optic Facility can be
rerouted within one hundred twenty (120) days after the occurrence, then this
Agreement will not terminate If the damage cannot be repaired or the Fiber Optic
Facility cannot be re-routed within such period of time, then either party may

            MAINTENANCE, REPAIR AND SERVICE RESTORATION PROCEDURES

1.    General Maintenance and Repair Responsibilities
      -----------------------------------------------

      1.1.   Southern Telecom Responsibilities.
             ----------------------------------

             1.1.1. Southern Telecom will notify the IFN Operations Center (the
telephone Number to supplied upon request) of any Fiber Optic Facility
maintenance or restoration service required.

             1.1.2. Southern Telecom will respond to Fiber Optic Facility outage
reports to Southern Telecom by the IFN Operation Center. Southern Telecom will
assess the damage and will provide an estimate of time required to restore the
Fiber Optic Facility. If temporary cable is used to restore service, a report
will be made by Southern Telecom as to the time of the permanent restoration.

      l.2.   IFN Responsibilities. IFN will notify the APC Telecommunications
             --------------------          
Network Control Center (the telephone Number to supplied upon request) of any
changes in configuration of the Route or any Fiber Optic Facility outage.

      1.3.   Fiber Optic Facility Interface Point.
             -------------------------------------

             1.3.1. The demarcation point for the Fiber cable will be the 
splice point at the end of the static line.

             1.3.2. IFN will be responsible for making all splices and isolating
troubles.

             1.3.3. IFN will provide single point of contact for reporting
troubles.

2.    APC Restoration Procedure for Optical Ground Wire ("OPGW").
      ----------------------------------------------------------

      The following lists the sequence of steps the parties will take to
restore service over the Fiber Optic Facility:

      2.1.   After a break in service is detected, all the parties will be
notified in the following sequence:

             (1)    IFN;
             (2)    Southern Telecom
             (3)    Power Dispatchers;
 

                                       23
<PAGE>
 
                                                                    CONFIDENTIAL

             (4)    APC Telecom; then
             (5)    On-Call Crews.

      2.2.   The location of the break will then be determined by: (1) APC
Telecom from a Regenerator; (2) IFN from its hub; (3) Power System Detection;
(4) Ground crews; or (5) Fly over.

      2.3.   Restoration teams will subsequently arrive on site to assess the
damage and select the fastest service restoration method.

      2.4.   APC will deliver a restoration trailer equipped with OPGW and all
support hardware to the site with the restoration crew. APC will maintain a reel
of dielectric cable for use for emergency restorations. If the permanent
restoration of OPGW requires an extended period of time, then the dielectric
cable will be rolled out on the right-of-way and temporarily installed to re-
establish service. Damaged OPGW will be cut out and the ends brought down at the
nearest towers to allow splicing on the ground. If the ends of OPGW are not
available in a reasonable time, then the dielectric cable will be brought back
to the nearest splice case and service rolled over.

      2.5.   Service will be rolled back when permanent OPGW repair is 
             completed.  

      2.6.   Restoration work will continue until regular service is restored.

3.    DDN ASSURED NETWORK RELIABILITY GUIDELINES
      -------------------------------------------

      The following procedures specify times and conditions when designated
tasks can be performed on the Fiber Optic Facility. Digital data traffic
activities will be governed by procedures administered and controlled at the APC

creditors, invokes any provision of law for the relief of debtors, or initiates
any proceeding seeking protection from its creditors; or 2) IFN violates any
applicable laws or other legal requirements which results in a material impact
on the System or System Segments; or 3) IFN fails to acquire and/or maintain
necessary Right-of-Way for the uninterrupted use of the System as required under
this Agreement; 4) IFN fails to perform any material obligation, which is not
associated with the physical operation of the System, under the terms of this
Agreement; 5) IFN fails to perform any material obligation regarding the
physical operation of the System under the terms of this Agreement.

     Such failure shall not be considered a default however if it is the result
of a material default on behalf of Sprint in its obligations under the
Maintenance Agreement.

     12.2  In the event of a default as described in (3) and (5) of Article 12.1
above, Sprint has the right, without the duty, and solely at its discretion to
cure the default if IFN is not using best faith efforts to cure the same. In
such event, IFN hereby appoints Sprint as its authorized agent, with authority
to negotiate and obtain licenses, lease renewals, or rights-of-way to allow for
the completion of construction or to allow for Sprint's uninterrupted use of the
System. IFN shall reimburse Sprint for any costs associated with curing such
default at a rate of two times Sprint's direct cost for labor and services and
one and one half times Sprint's direct costs for materials and fees. Sprint may
offset such reimbursement against any fees due and owing hereunder by Sprint.
Sprint shall provide an itemized invoice to IFN for any amounts offset.

     12.3  If any event of default continues for thirty (30) days after written
notice thereof, Sprint has the right, but not the duty, and solely at its
discretion to initiate any of the actions that follow:

completion of the System, termination shall be immediate and effective upon
notice. In such event, IFN hereby releases and discharges Sprint of and from any
and all claims, causes of action, damages or liabilities, known or unknown,
incurred by reason of or in any way growing out of the use of the System and
Route or related to this Agreement. IFN's liability for the liquidated damages
set forth in Section 1.7 shall cease upon termination of the Agreement.

     b)   To cure the event of default to the extent Sprint deems necessary to
allow for the continued use of the Sprint Fibers by Sprint or to complete
construction of the System for use by Sprint. In such event, IFN hereby appoints
Sprint as its authorized agent, with authority to negotiate and obtain licenses,
lease renewals, or rights-of-way to allow for the completion of construction or
to allow for Sprint's uninterrupted use of the Sprint Fibers. IFN shall
reimburse Sprint for any costs associated with curing such default at a rate of
two times Sprint's direct cost for labor and services and one and one half times
Sprint's direct costs for materials and fees. Sprint may offset such
reimbursement against any fees due and owing hereunder by Sprint. Sprint shall
provide an itemized invoice to IFN for any amounts offset.

                                                                      PAGE 13
<PAGE>
 
     12.4  If any portion of the System experiences performance which fails the
material requirements as set forth in the Exhibits or in industry standards of
comparable systems with current and like technology, which results in an
interruption in Sprint's ability to use or a material degradation of the System,
then Sprint's obligation for payment here under shall immediately cease for the
duration of such interruption or degradation on a pro rata basis in one
sixteenth increments for each Sprint Fiber affected (one twenty fourth
increments for each Sprint Fiber affected on the Accepted System Segment -
[_____] Extension) until the same is cured, as demonstrated by IFN to the
reasonable satisfaction of Sprint. Notwithstanding any other provision of this
Agreement to the contrary, if Sprint exercises its remedy to cease payment of
its monthly obligation to IFN due to an alleged material default by IFN, then
IFN shall have the right to draw upon its Letter of Credit referenced in Article
5 hereof to satisfy IFN's monthly financial obligations related to the System,
provided that IFN may not reduce the available balance under the Letter of
Credit to an amount less than [__________] pursuant to this Article 12 without
the prior written consent of Sprint. Additionally, the amount available under
the Letter of Credit must be reinstated to the maximum amount required pursuant
to Article 5 hereof within twelve (12) months after the date IFN first makes any
draw under the Letter of Credit pursuant to this Article 12.

     12.5  Sprint shall be in default of this Agreement if: 1) Sprint becomes
insolvent, liquidates, is adjudicated as bankrupt, makes an assignment for the
benefit of creditors, invokes any provision of law for the relief of debtors, or
initiates any proceeding seeking (including payment obligation) protection from
its creditors; or 2) Sprint fails to perform any material obligation under the
terms of this Agreement. If any such event of default continues for thirty (30)
days after written notice thereof, IFN has the right, but not the duty, solely
at its discretion to terminate this Agreement. Such termination shall be
immediate and effective upon notice. In such event, Sprint hereby releases and
discharges IFN of and from any and all claims, causes of action, damages or
liabilities, known or unknown, incurred by reason of or in any way growing out
of the use of the System and Route or related to this Agreement. It is not
intended that Sprint release IFN from claims relating to this Agreement such
that IFN caused or contributed to Sprint's material default hereunder.

dispute, controversy or claim to arbitration in accordance with the following
procedures:

     (a)   Either party may demand arbitration by giving the other party written
           notice to such effect, which notice shall (i)describe, in reasonable
           detail, the nature of the dispute, controversy or claim, and (ii)

           issue in dispute.

     (b)   Within thirty (30) days after the other party's receipt of such

     (c)   The two arbitrators so named shall promptly select a third arbitrator
           who also is experienced in the subject matter of the issue in
           dispute. The arbitration shall be heard by a panel of the three
           arbitrators so chosen (the "Arbitration Panel"), and the resolution
           of the dispute, controversy or claim shall be determined by a
           majority vote of the Arbitration Panel. The Commercial Arbitration
           Rules of the American Arbitration Association shall govern the

           between the Parties as the Arbitration Panel may deem equitable the
           costs incurred by the prevailing party.

                                                                      PAGE 15
<PAGE>
 
     (e)   The party demanding arbitration shall request the Arbitration Panel
           to (i) allow for the Parties to request reasonable discovery pursuant
           to the rules then in effect under the Federal Rules of Civil
           Procedure for a period not to exceed sixty (60) days prior to such
           arbitration and (ii) require the testimony to be transcribed. No
           findings of fact or opinions of law shall be required to be made by
           the arbitrators.

     (f)   Any award rendered by the Arbitration Panel shall be final,
           conclusive and binding upon the Parties and any judgment thereon may
           be entered and enforced in any court of competent jurisdiction.

     15.2  Exclusive Remedy. Other than any action necessary to enforce the
           ---------------- 
award of the Arbitration Panel, the Parties agree that the provisions of this

                                  EXHIBIT G 
                     AGREEMENT FOR USE AND NON-DISCLOSURE
                          OF CONFIDENTIAL INFORMATION

THIS AGREEMENT, made effective as of the 26th day of January 1995, by and 
between Sprint Communications Company L.P., a Delaware Limited Partnership 
("Sprint"), having an office at 903 East 104th Street, Kansas City, MO 64131, 
and Interstate FiberNet, a Georgia General Partnership ("Carrier"), having an 
office at 910 First Avenue, West Point, GA 31833, is to assure the protection 
and preservation of the confidential and/or proprietary nature of information to
be disclosed or made available to each other in connection with an agreement 
regarding telecommunications services contemplated by Carrier and Sprint ("the
Party(ies)").

WHEREAS, the Parties contemplate entering into business and/or technical 
discussions relating to:

Telecommunications Services

NOW, THEREFORE, in reliance upon and in consideration of the following 
undertakings, the Parties, for themselves, their subsidiaries and their 
affiliates, agree as follows:

     1.  All information disclosed to the other Party shall be deemed to be
         confidential and proprietary (hereinafter referred to as "Proprietary
         Information") provided that written information is clearly marked in a
         conspicuous place as confidential or proprietary, and verbal
         information is immediately confirmed in writing as confidential or
         proprietary.

     2.  Each Party agrees to use the Proprietary Information received from the
         other Party only for the purpose stated above. No other rights, and
         particularly licenses, to trademarks, inventions, copyrights, or
         patents are implied or granted under this Agreement.

     3.  Proprietary Information supplied shall not be reproduced in any form 
         except as required to accomplish the intent of this Agreement.

     4.  The receiving Party shall provide the same care to avoid disclosure or
         unauthorized use of the Proprietary Information as it provides to
         protect its own proprietary information, but in any event at least
         reasonable care. It is agreed that all Proprietary Information shall be
         retained by the receiving Party in a secure place with access limited
         to only such of the receiving Party's employees or agents who need to
         know such information for purposes stated above.

     5.  All Proprietary Information, unless otherwise specified in writing,
         shall remain the property of the disclosing Party, shall be used by the
         receiving Party only for the purpose intended, and such Proprietary
         Information, including all copies thereof, shall be returned to the
         disclosing Party or destroyed after the receiving Party's need for it
         has expired or upon request of the disclosing Party, or, in any event,
         upon termination of this Agreement.

     6.  It is understood that the term "Proprietary Information" does not 
         include information which:

              a)  has been published or is now or may become in the public 
                  domain through no fault of the receiving Party;

              b)  prior to disclosure hereunder is property within the 
                  legitimate possession of the receiving Party;

              c)  subsequent to disclosure hereunder is lawfully received from
                  a third party having no obligation not to disclose;

              d)  is independently developed by the receiving Party through
                  parties who have not had, either directly or indirectly,
                  access to or knowledge of such Proprietary Information;

              e)  is transmitted to the receiving Party after the disclosing
                  Party has received written notice from the receiving Party
                  that it does not desire to receive further Proprietary
                  Information.

              f)  is required to be disclosed pursuant to court order or as
                  otherwise required by law, on the condition that reasonable
                  written notice of the requirements for such disclosure is
                  given to the disclosing party as soon as possible prior to
                  making any disclosure and the receiving party to such
                  requirements cooperates as the other may reasonably request in
                  resisting the disclosure or disclosing only under a protective
                  court order or other entity or agency.

     7.  Each Party agrees not to reveal this relationship with the other Party
         to any third parties except as contemplated by Paragraph 4 of this
         Agreement.

     8.  Damages, being difficult to ascertain in the event of violation of this
         Agreement, the Parties agree that, without limiting any other rights 
         and remedies of each other, upon breech hereof, an injunction may be
         sought by the non-breaching Party to protect its rights hereunder.

     9.  This Agreement shall continue in full force and effect so long as
         either Party shall possess the Proprietary Information of the other
         Party. This Agreement may be terminated at any time by mutual
         agreement, or by either Party upon sixty (60) days written notice to
         the other Party; provided that such unilateral termination of this
         Agreement shall not relieve the recipient Party of its obligations
         under this Agreement with respect to Proprietary Information exchanged
         prior to the effective date of termination.

                           Gulf States FiberNet and
                      Sprint Communications Company L.P.


THIS AMENDMENT IS entered into, effective as to this 8TH day of AUGUST

(hereinafter referred to as "GSF"), having an address at 910 First Avenue, West
Point, GA 31833, GSF and Sprint collectively referred to as the "Parties".

BACKGROUND:

     InterState FiberNet ("IFN") and Sprint entered into the Telecommunications
System Agreement, dated January 26,1995 and as amended on July 25,1995
("Agreement"), and such Agreement was assigned by IFN to GSF pursuant to Article
16.10 of the Agreement; and

     The Agreement obligates GSF to design, engineer, construct or cause to be
constructed facilities and acquire appropriate interests in real property or
other rights, all as may be required to provide, operate, and maintain a
telecommunications fiber optic system between [____________] and [_________]
(hereinafter referred to as "Route" and as shown in Exhibit A2); and

     The Agreement obligates GSF to provide Sprint space within GSF buildings
along the Route (hereinafter "Sprint Space"), including the [_____] regenerator
located at [________________________________________]; and

     Sprint does not currently require the entire minimum of 100 square feet of
Sprint Space at the [_______] regenerator and agrees to allow GSF use of any
space not currently required by Sprint to supply its customers with
telecommunications services.


THEREFORE, the Parties agree as follows:

1. As if the Effective date of this Amendment No. 2, GSF may use Sprint Space
not currently being utilized by Sprint at the [_____] regenerator site, provided
that GSF's use of the space at the [_____] regenerator site will in no way have
any effect on current Sprint fibers, equipment, or relay racks currently
installed at the site.

2. Sprint will give GSF nine (9) months notice to re-acquire its space at the
[_____] regenerator. Immediately upon notice, GSF will take the appropriate
actions to restore the original space for Sprint's use, provide an additional
building, or attachment to the existing building which will meet or exceed the
specifications in Exhibit D of the Agreement. This space will be ready for
Sprint to occupy within nine (9) months from the date of notice to
GSF.

3. Sprint may revoke GSF's right to utilize the Sprint Space immediately upon
notice to GSF that Sprint Fibers, equipment, or relay racks currently installed
are materially, adversely impacted by GSF's use of sprint Space.

4.  During GSF's use of Sprint Space, all obligations of Sprint to GSF in
reference to or applicable to that portion of the Sprint Space shall cease.

effect.

IN WITNESS WHEREOF, the Parties hereto have executed this Amendment on the day

above.

   9.1    ALLTEL shall, with regard to the ALLTEL Route, provide routine route
surveillance, Cable locates, "Call Before You Dig" service, encroachment
monitoring, easement and permit administration. and preventive maintenance of
the regenerator equipment and electricity at regenerator sites ("Routine
Maintenance").  Subsequent to the Completion Date, IFN shall, by wire transfer,
pay to ALLTEL for performing such services, an annual fee in the amount of Two
Hundred Thousand Dollars ($200,000) (the "Payment").  The first Payment will be
due and payable thirty (30) days after the Completion Date.  Thereafter, each
Payment shall be invoiced annually on or after each anniversary date of the
Completion Date during the Initial Term or any Renewal Term.  The Payment shall
be due by IFN within thirty (30) days of receipt of invoice therefor.  The
Payments may be adjusted annually, at ALLTEL's sole discretion, beginning with
the first anniversary date, for increases in the United States Bureau of Labor
Statistics, CPI-U All Services Index (unadjusted), as published (the "Index").
Said adjustment shall be hereinafter referred to as "CPI-U Adjustment".  Each
Payment, as adjusted by the CPI-U Adjustment, shall be equal to the product of
the Payment specified herein multiplied by the fraction (a) whose denominator is
the CPI-U ALL Services Index for March of the previous calendar year for which
the adjustment to the Payment is being made, and (b) whose numerator is the CPI-
U ALL Services Index for March of the current year.  The adjusted Payment shall
remain in effect until the next annual Payment is due when a new adjusted
Payment fixed pursuant to this provision shall become effective.  In no event
shall the  amount of the Payment as adjusted pursuant to this provision be less
than the amount of Payment in effect for the immediately preceding year.  The
parties agree that the Index for March 1997 is defined as 160.  In the event
that the Bureau of Labor Statistics (or any successor organization) changes the
current base of the CPI-U from 1982-84 = 100, the calculation of a Payment under
this provision shall be adjusted to ensure that ALLTEL receives the same amount
as it would have received, had the base not been changed.  In the event the
Bureau of Labor Statistics or any successor organization no longer publishes the
CPI-U, ALLTEL shall, subject to IFN's agreement, which shall not be unreasonably
withheld, designate the statistical index it deems most appropriate for
calculation of adjustments to a Payment, and from the date the CPI-U ceased to
be published, such index shall be used to make adjustments in a Payment under
this provision.

   9.2    IFN shall, with regard to the IFN Route, provide routine route
surveillance, Cable locates, "Call Before You Dig" service, encroachment
monitoring, easement and permit administration. and preventive maintenance of
the regenerator equipment and electricity at regenerator sites ("Routine
Maintenance").

for performing such services, an annual fee in the amount of Two Hundred
Thousand Dollars ($200,000) (the "Payment"). The first such Payment will be due
and payable thirty (30) days after the Completion Date. Thereafter, each such
Payment shall be due annually on each anniversary date of the Completion Date

ensure that IFN receives the same amount as it would have received, had the base
not been changed. In the event the Bureau of Labor Statistics or any successor
organization no longer publishes the CPI-U, IFN shall, subject to ALLTEL's

   16.1   All proprietary information disclosed and identified as proprietary at
the time of disclosure by either party hereto to the other party shall be kept
confidential by the other party, shall be used only in performing under this
Agreement and may not be used for other purposes, except upon such terms as may
be agreed upon in writing by the parties.  Information which is considered
confidential or proprietary in nature will be identified as such by a marking
placed on the information when such information is in tangible form.  Such
marking may take various forms from time to time but will clearly specify the
proprietary nature of the information.  In addition, the parties shall use
reasonable efforts to assure that the terms and provisions of this Agreement
shall not be disclosed by either party to third parties except third parties
rendering professional consulting services to the disclosing party or third
parties to whom the disclosing party is seeking to provide services and only
following the execution by the third parties of agreements of confidentiality
and nondisclosure that are consistent with the provisions of this Agreement.
However, consideration paid pursuant to this Agreement shall not be disclosed to
such third parties to whom the disclosing party seeks to provide service.

   16.2   Neither party shall be required by this Article XVI to keep
confidential any information which is publicly known, other than by breach of

identified as proprietary; which becomes available to such party without
restriction from a third party; which is developed at any time by the receiving
party independently of any disclosures hereunder; or which is required to be
disclosed by law or by any governmental agency or court of law having
jurisdiction.  In the event a disclosure is required by law or by any
governmental agency or court of law, the party required to make such disclosure
shall give the other party notice of such requirements in sufficient time to
allow the other party to seek a protective order from such court or agency
restraining the disclosure or shall itself seek such protective order as is
reasonably acceptable to and requested by the other party.

   16.3   Neither party shall use the name, trade name, service mark or
trademark of the other party or the existence of this Agreement in any
promotional or advertising material without the prior written consent of the
other party.

illegal or otherwise "improper" purposes.  Neither party shall pay any

value.  If either party has reasonable cause to believe that one of the
provisions in this Article has been violated, it, or its representative, may
audit the books and records of the other party for the sole purpose and only to
the extent necessary to examine compliance with such provisions.


                  ARTICLE XVIII.  RELATIONSHIP OF THE PARTIES

obtain, pay for and maintain insurance for at least the coverages and amounts of
coverage as set forth below and shall provide to the other party certificates
issued by insurance companies satisfactory to such other party to evidence such
coverages. Such certificates shall provide that there shall be no termination,
non-renewal or reduction of such coverage without thirty (30) days' prior
written notice to such other party. In the event of any failure by either party
to comply with the provisions of this Article, the other party may, at its
option, on notice to such party, either suspend any 

                                       14
<PAGE>
 
obligations owned to such party until there is full compliance with this
Article, or contract for such insurance at such party's expense. The coverages
and amounts of coverage required are:

     a.   Worker's Compensation insurance complying with the laws of the state

          aggregate, to include products and completed operations; broad form
          property damage including completed operations; personal injury
          liability with deletion of the contractual liability exclusion; and
          broad form blanket contractual liability for liabilities assumed by
          ALLTEL or IFN for work to be performed under this Agreement by ALLTEL,
          IFN or independent contractors. The following exclusions shall be
          deleted, so that coverage shall apply to them: (X) explosion; (C)
          collapse; (U) underground property damage; (D) underground resources
          and equipment.

     c.   Commercial Automobile Liability insurance with a combined bodily

          $1,000,000 per occurrence, to be in excess of the liability coverages
          in a, b and c above.

   In the event either party fails to obtain the required certificates from any
contractor and a claim is made or suffered, such party shall indemnify and hold
harmless the other party from any and all claims for which the required
insurance would have provided coverage.

   In the event coverage is denied or reimbursement of a properly presented
claim is disputed by the carrier for insurance provided in (a) through (c)
above, the party carrying such coverage shall make good faith efforts to pursue
such claim with its carrier.

   19.2   ALLTEL and IFN will obtain from the insurance companies providing the
coverages required by this Agreement the permission of such party to waive all
rights of subrogation and such party does hereby waive all rights of said
insurance companies to subrogation against the other party, its parent
corporation, affiliates, subsidiaries, assigns, officers, directors and
employees or any other party entitled to indemnify under this Agreement.

   19.3   Either party, in lieu of providing the coverages required by this
Agreement, may self insure.

   19.4   Maintenance by a party of any such insurance coverages shall not,
however, be deemed a limitation of that party's liability hereunder.


                    ARTICLE XX.  EXCUSE FOR NONPERFORMANCE

   23.1   For any waiver of any right, option or privilege hereunder to be
binding it must be made in writing and signed by both parties.  No waiver of the

                           ARTICLE XXIV.  ASSIGNMENT
                                          ----------

subsidiaries or those of its parent company ("AFFILIATES") that are also
receiving all of the assets of the party that are necessary to perform its
obligations under this Agreement , without the express prior written consent of
the other Party which consent shall not be unreasonably withheld and/or delayed.

          FiberNet, Inc. and do further acknowledge and agree that the consent
          of ALLTEL shall not be required for these events.

dispute shall not be resolved by the parties within a reasonable time, not to
exceed thirty days unless extended by mutual agreement of the parties, then
either party may elect to pursue any other legal action it deems appropriate to
resolve such dispute.  Nothing in this paragraph shall be deemed a waiver of any
rights either party may have to pursue any 

                                       16

1.0  GENERAL

1.01 This document will provide direction and standardization in splicing 
procedures for fiber optic cable. All construction will be done in strict 
compliance with the 1996 National Electrical Safety Code and all other federal, 
state and local regulations.

1.02 This exhibit sets forth general principles of fiber optic cable 
construction, and incorporates comprehensive details and specifications 
concerning fiber optic cable construction contained in the following practices: 
ASP (ALLTEL System Practice) 290-350-456, ASP 290-350-455, ASP 290-400-605, ASP 
290-500-400, ASP 540-850-005, ASP 540-850-010, ASP 540-850-015, SRP (Southern 
Region Practice) 290-630-610 and SRP 93-2020.

2.0  GLASS FIBER SPECIFICATIONS:

2.01 All glass fiber used in any fiber optic cable will adhere to the following 
specifications. Specific circumstances may necessitate a variance from these 
perimeters. In these instances a case by case evaluation will be made.

           1.    Single mode fiber
           2.    8.3 micron core nominal
           3.    Cladding diameter 125 +/- 2 micron
           4.    Coated diameter 250 +/- 15 micron

                                       1


<PAGE>
 
           5.     Core eccentricity not more than 1.0 micron
           6.     Dispersion not to exceed 2.6 psec/nm-km @ 1310nm and
                  typically less than 1 psec/nm-km @ 1550 nm.
           7.     Attenuation per fiber not to exceed 0.40db/Km @ 1310 nm
                  0.30db/Km @ 1550 nm


2.02 Copies of the manufacture's test results are to be retained and become 
part of the as-built documentation.

3.0  BASIC SPLICING PROCEDURES

3.01 Each fiber will be tested at each splice and the results recorded on the
form provided in Attachment I of Exhibit 3. These forms will become part of the 
as built documentation.

3.02 Splice cases will be standard manufactured Preformed stainless steel
Fiberlign or injection-molded Coyote splice cases. Splice cases will be
installed in accordance with the manufacture's recommended procedures. All
splices will be protected fusion splices.

3.03 When the cable sheath contain armor, each sheath will be bonded to a #6
insulated ground wire. Each sheath will be isolated from the others sheaths and
the splice case. The #6 insulated ground wires will be connected to a driven
ground rod that has a ground resistance reading of not more than 25 ohms.

3.04 Standard procedure for aerial or buried plant requires all splice cases to
be at ground level in a Reltec OPFOBD7 cabinet. The cabinet will also contain
storage for approximately 100' of cable. The stored cable will permit the case
to be relocated to an environmentally controlled area for splicing.

3.05 In location where ground level facilities are not permitted, subsurface
splices vaults will be placed. The vaults must permit ready access to the splice
case. This vault will also provide storage for cable which will permit the
splice case to be relocated to an environmentally controlled area for splicing
operations. Direct buried splices are not to be placed without written approval
of management.

4.0  CABLE SPECIFICATIONS:

4.01 Fiber optic cable for aerial, buried or underground construction will be
single mode standard production cable, with a high or medium density
polyethylene jacket. All cable will be filled or contain a water blocking
compound. The fibers will be color coded with industry standard colors. The
cable may be loose tube, central tube or ribbon type constructed. Armored cable
will contain an

                                       2
<PAGE>
 
overlapping coated steel armor. Metallic strength members are acceptable only in
armored cable.


5.0 PLACEMENT OF AERIAL CABLE

5.01 Aerial splices will be brought down the pole and placed in a BPFOBD7 
cabinet. If the cable sheath contains any metallic member it will be bonded to a
#6 ground wire and connected to a driven ground rod. Sufficient cable will be 
stored in the cabinet to allow the splice to be relocated to an environmentally 
controlled area for slicing.

5.02 A 3" drip loop will be placed in the fiber cable at each pole. Attached to 
the cable at the drip loop will be an identification tag stating the owner of 
the cable.

6.0 PLACEMENT OF DIRECT BURIED CABLE

6.01 Splices in direct buried plant will be brought to the surface and placed in
a BPFOBD7 cabinet. The armor and any metallic member in each sheath will be
bonded to an insulated #6 ground wire and connected to a driven ground rod in
the cabinet. Each sheath will be isolated from the others sheaths and the splice
case. The #6 insulated ground wires will be connected to a driven ground rod
that has a ground resistance reading of not more than 25 ohms. Sufficient cable
will be stored in the cabinet to allow the splice to be relocated to an
environmentally controlled area for splicing.

6.02 The buried cable will be placed at a minimum depth of 36" measured from the
top of the cable to the surface of the ground. Buried warning tape is to be 
placed at a depth of 18" to 24" below grade at the time of construction.

6.03 Warning signs will be located along the route, culverts and at road 
crossings. Signs will be placed at approximately quarter mile intervals and at 
other locations that are susceptible to excavation. Signs are to be tubular in 
design, providing 360(degrees) visibility, and display the 1-800 call before you
dig telephone number.


7.0 PLACEMENT OF UNDERGROUND DUCT CABLE

7.01 Cable may be placed in duct by pulling or blowing the cable into the duct. 
At no time should the pull on cable being placed in the duct exceed the 
recommended tensile load rating of the manufacturer, typically 600 pounds.

7.02 Cable placed in manholes will wrap the hole a minimum of two times to 
provide slack for restoration. The cable will be identified with a tag in each 
hole.

                                       3
<PAGE>
 
7.03 Splice cases located in manholes will be securely mounted on the cable 
racking and identified. Sufficient cable will be stored in the manhole to allow 
the splice to be relocated to an environmentally controlled area for spicing.

8.0 CABLES ENTERING BUILDINGS

8.01 Cables entering buildings will have two separate entrances where ever 
possible. The intent is to promote diverse routing at every opportunity.

8.02 The armor and any metallic members of any cable entering a building will be
severed and bonded with a #6 insulated ground wire at the first opportunity upon
entering the building. This will normally occur at the point the outside plant 
cables are spliced to the inside cables. This can be a splice case or a splice 
cabinet. The #6 ground wire will be bonded to the hot side of the single point 
MGN bar. Cables that do not contain metal and therefore do not require isolation
and grounding should be identified as non-metallic.

1.0 GENERAL

1.01 This practice will provide direction and standardization in splicing and 
acceptance of fiber optic cable. This practice sets the minimum standard tests 
that are to be performed during construction, acceptance and restoration. It 
does not limit testing to these tests if there is reason to suspect the presence
of a condition that would render a cable unserviceable.

1.02 The procedures are applicable to all aerial, buried, or underground fiber 
optic cable. These procedure will be the standard for the acceptance. All fiber 
optic cable, regardless of length, will pass the tests prescribed in this 
practice.

1.03 This practice also describes the tests that are required on existing cable 
that is being considered as feeder for digital loop carrier.

1.04 The performance of the tests and the recording of the test data will be the
responsibility of the engineering department. If independent contractors are 
used for construction the engineer and a representative of the contractor will 
perform the test jointly. The results of the tests will be recorded on the 
appropriate Southern Region Cable Acceptance form. The acceptance form for fiber
optic cable is shown in Attachment I.

2.0 GENERAL SPLICING SPECIFICATIONS

2.01 All construction splicing will be protected fusion splices and all test 
results will be recorded. Individual splices should be evaluated with the OTDR 
during the actual splicing phase of the project. No splice should have a loss of
more than .1db. If.1db loss is not obtained after three (3) attempts, the splice
may exceed the .1 db loss

                                       1


<PAGE>
 
requirement but is not to exceed .5db. The engineer is to be consulted if more 
than .5db occurs. High losses can be the result of core mismatch, poor core 
concentricity or irregular core shape. These conditions are not likely to be 
corrected with repeated attempts at splicing. This condition is exceptional and 
should occur infrequently and only on single fibers in the slice. If difficulty 
is experienced in obtaining splices of .1db or less on all but an exceptional 
fiber, procedural or mechanical causes are to be suspected.

2.02 The splicing of different manufacturer's fiber can also result in 
difficulty in obtaining low loss splices. This is the result of inherent 
difference in the glass of the fiber. If this occurs, all the fibers in the 
splice are usually affected. For this reason it is suggested not to mix cable 
from different manufacturers if possible.

2.03 Protected fusion splices are the first choice for restoration splicing. 
Mechanical splices may be utilized only for temporary restoration purposes when 
fusion capabilities are not available. All mechanical splices will be replace
with protected fusion splices as soon as practical.

2.04 When circumstances do require the use of mechanical splices the splice lose
will not exceed .20 db insertion loss with a minimum reflective loss not less 
than 35.0 db.

3.0 OPTIC CABLE ACCEPTANCE-GENERAL 

3.01 Fiber optic cable will pass the following acceptance test prior to being 
accepted and placed in service. Fiber optic cable has no length exceptions and 
all new cable will be tested. The test results will be recorded on the Southern 
Region Cable Acceptance - Fiber Optic form shown in Attachment I.

3.02 REQUIRED FIBER OPTIC CABLE TEST

      Armor to ground
      Armor bond continuity
      End to end OTDR traces
      End to end power meter reading

4.0 ARMOR TO GROUND TEST

4.01 The armor to ground test for buried fiber optic cable will be performed 
using a megohmmeter in a similar manner to that described for the shield to 
ground test used on

                                       2
<PAGE>
 
copper cable. A value of 161,000 ohm-kilometer should be considered the minimum 
acceptable value of the armor ground resistance.

4.02 For example, at 161,000 ohms per kilometer, for a 6KM (3.7 mile) fiber 
cable would be estimated at approximately 26,833 ohms. This is calculated by 
dividing 161,000 ohms by 6KM, the length for the estimated ohms resistance.

4.03 To obtain the actual value for the cable, the actual test set reading is 
multiplied by length of the cable. This value is then compared to the estimate 
to determine the acceptability of the cable. The actual results must exceed the 
estimated value.

4.04 The intent of testing the armor in the fiber cable is to ensure no damage 
was incurred during placement. If sheath damage did occur during placement the 
testing will show a ground fault.

4.05 To record the results of the armor to ground test the following information
is entered as shown in Attachment II. Enter N.A. if the cable is nonmetallic.

     1. Enter the work order number authorizing the cable construction.

     2. Enter the type, manufacture and number of fibers of the cable being 
     tested.

     3. Enter the exchange the cable is located.

     4. Enter the number of sheets needed to record the test data
 
     5. Enter the pole or pedestal number where the test equipment is located to
     perform the test. If more sections of cable are tested than can be shown,
     go to a second sheet.

     6. Enter the pole or pedestal number that is at the far end of the section 
     of cable being tested.

     7. The megohms reading is entered in block number 7. 

     8. Enter the actual date the test was performed.

     9. The name of the person performing the test is entered in block 9.

5.0 ARMOR BOND CONTINUITY TEST

                                       3
<PAGE>
 
5.01 The armor bond continuity test will be performed after the cable is in
place and all splices are complete. In testing the armor bond continuity in
fiber optic cable a VOLT-OHM meter will be used to read the resistance of the
armor and check for opens.

5.02 To perform this test the far end of the cable armor is to be grounded. The
near end will be isolated. Place the positive lead from the VOLT-OHM meter on
the armor. The common lead is then grounded. The resulting reading should show
very low resistance. Typical results for fiber cable are 33.6 ohms per KM for
cable constructed with only metallic armor. If the cable also contains metallic
strength members embedded in the sheath a resistance figure of 21.5 ohms per KM
should be used. The actual reading will depend on the length of the cable.

5.03 To ensure the full length of the cable is being read, a second reading is
taken with the far end ground isolated. The result should show an open,
indicating that the ground that was read the first time was the far end ground.

5.04 If a fiber optic cable is made up of sections of armored and dielectric
cable each section of armored will need to be tested individually.

5.05 To record the results of the armor bond continuity test enter the following
information in blocks 10 through 14 as indicated in Attachment II. Dielectric
cable will be indicated with N.A.

           10. Enter the pole or pedestal number where the test equipment is
               located while performing the test. If more sections of cable are
               tested than can be shown go to a second sheet.

           11. Enter the pole or pedestal number that is at the far end of the
               section of cable being tested.

           12. Enter the result of the VOLT-OHM meter test as good or fail.

           13. Enter the actual date the test was performed.

           14. Place the name of the person performing the test.



6.0  END TO END OTDR TRACES

6.01 Although traces are not an actual acceptance test, OTDR traces are required
final documents. A trace will be taken of each fiber from both directions. These
will serve as a permanent base line record for each fiber. The traces show the
fiber attenuation,

                                       4
<PAGE>
 
splice loss, location of splices and overall length. A trace of each individual 
fiber is required.

6.02 OTDR traces are to be maintained as permanent record in each central office
in which the cable appears, the work order file and with the restoration kit. 
This information is invaluable in the event of restoration and is required in 
the SRP290-630-610, Fiber Optic Emergency Restoration Guidelines.

6.03 The OTDR will be connected to each fiber through the patch panel. Consult 
the operator's manual for instructions. Each fiber trace should also indicate 
the location from which the trace was made and the number of the fiber.

6.04 The fact that OTDR traces were made is recorded on the acceptance form as 
indicated in Attachment II.

     15. Enter the central office where the OTDR is located during the test.

     16. Enter the date the traces were made.

     17. Enter the central office where the OTDR is located to perform the 
     traces for the direction opposite to that shown in block 15.

     18. Enter the date the traces were made.


7.0 END TO END POWER METER READING

7.01 The end to end loss of the fiber is the deciding factor in fiber optic 
cable acceptance. This tests evaluates both the fiber and splices. The loss 
associated with individual splices is not a specific function of acceptance 
testing.

7.02 To accomplish the end-to-end loss test, a power meter and light source are 
used to determine the actual attenuation of the fiber and splices over its 
entire length. The source of the light can be the multiplexed equipment or a 
separate light source. Operator's manuals should be consulted for specific 
instructions.

7.03 To perform this test a known quantity of light is introduced into the fiber
with a light source. This is determined by using the power meter to read the 
out put of the light source. The fiber is then connected to the light source.
The amount of light reaching the far end is then read with the same power meter.
The known source light figure is then subtracted from the reading taken at the
far end with the power meter. The difference is the actual loss incurred in the
entire length. All of the fibers will be tested.

                                       5
<PAGE>
 
7.04 This process is then repeated in the opposite direction. It is not unusual 
for readings taken from one direction to differ from readings taken in the 
opposite direction.

7.05 Compare the estimated loss on the loss budget provided by engineering to 
the results of the test. If the figures are within 10% plus or minus, the cable 
is acceptable. If a greater difference is found the transmission engineer should
be informed of the discrepancy. The cable will not be considered as accepted 
until the discrepancy is explained. The loss of the fiber and splices combined 
determine the acceptability of the cable.

7.06 The end-to-end power meter loss test results will be recorded as indicated 
on Attachment II.

     19.   Enter the central office or location were the light source is
           located.
     
     20.   Enter the central office or location that is the far end of the cable
           being tested.

     21.   Enter the number of the fiber. If a fiber cable is being tested that 
           is larger than 16 fibers a second sheet is required.
 
     22.   Enter the db reading of the light source. This should be a constant 
           for all the fibers tested from that location at that time.

     23.   Enter the power meter reading at the far end. 

     24.   Enter the result of subtracting the source light from the end
           reading.

     Blocks 25 through 30 reflect the similar information as 19 through 24 but
     with readings from the opposite direction. This permits directional
     comparison of the same fiber.

     31.   The engineer indicates the cable as being accepted or rejected.

     32.   Enter the date of the final acceptance.

     33.   Enter the name of the engineer accepting or rejecting the cable.

     34.   Enter the name of the representative of construction who jointly 
           performed the tests.

7.07 The completed form is to be maintained in each central office in which the 
cable appears, the work order folder and with the restoration kit.

1.0 GENERAL

1.01 The following specifications define the minium requirements for as-built 
documentation. Documentation will be exchanged by IFN and ALLTEL for their 
respective fiber facilities. These documents will be combined with the 
acceptance testing forms and any other pertinent information to serve as the 
source data during a restoration. Without accurate and detailed records of the 
plant as it was built, restoration activities will be greatly hampered.

2.0 BASIC INFORMATION

2.01 Basic as-built information will include the date of placement, size, type 
and manufacture of the fiber cable. Included with this will be the cable 
manufacture's reel test and all other acceptance test results.

3.0 FACILITIES DRAWINGS

3.01 Facility drawings will show the actual route, location and depth of the 
fiber cable as constructed. Details are to include road names, splice points, 
road crossings, conduit, sequential readings of the cable and any other 
specifics that will assist in any restoration activity.

<PAGE>
 
     D.    Operation of OTDR and power meters.

III. Outside plant span acceptance will require making permanent documentation 
from OTDR readings and completing end-to-end attenuation measurements:

     A.    Create permanent records of span performance by printing hard copies
           of OTDR traces (footprints) or by entering OTDR data into an
           auxiliary personal computing program.

     B.    Demonstrate the ability to properly complete end-to-end attenuation
           measurements using 1310nm and 1550mn wavelength sources and power
           meters.

1.2  ALARM REPORTING

1.   Alarms from all ALLTEL locations will be received in the ALLTEL Operations
     Center (AOC). The alarms will be sent via alarm sending devices from each
     site to the AOC.

2.   Each alarm occurrence will be logged by the AOC duty technician. He or she
     will verify the alarm and initiate contact with the appropriate maintenance
     personnel. The AOC personnel will coordinate repair activity and assist the
     maintenance people as needed.

3.   The ALLTEL Operation Center will keep management informed as to the status
     of the repair work that is service affecting and estimated completion time.

4.   Upon resolution of the alarm condition, the AOC technician will then 
     complete the Trouble/Alarm Report.

5.   The AOC will complete a Service Affecting Trouble Log.

6.   An escalation list for all ALLTEL maintenance personnel will be kept in the
     AOC.


1.3  RESTORATION PROCEDURES

The following procedures will be followed when a fiber optic cable has been 
severed. Proposed restoration objective is six (6) hours.

1.   The cable maintenance technicians should immediately obtain all necessary
     equipment and materials required to repair a cable cut from restoration
     stores and should report with those items as quickly as possible to the
     electronics equipment site


                                       2
<PAGE>

     nearest the suspected cable cut.

2.   The Duty Man should obtain all necessary test equipment, including Optical
     Time Domain Reflectometer (OTDR), Optical Power Meter, and should report
     (in a 2-way radio or mobile telephone equipped vehicle) to the electronics
     site.

3.   Through on-site analysis of the local alarms displayed on the equipment at
     each site, the Duty Men are to confirm whether a cable cut has taken place.
     If a cable cut has not occurred, the cable maintenance personnel should be
     released and the Duty Men should take whatever action is required to
     correct the trouble, keeping their AOC informed at all times. If a cable
     cut has taken place, the Duty Men should coordinate their efforts to do the
     following:

     A.    Dispatch cable maintenance personnel (from each company if two 
                                                      ----
           companies are involved) to ride the cable route in an effort to
           physically locate the point of the cable cut.

     B.    Alert the AOC that a cable cut has occurred and provide expected 
           restoration time.

     C.    The AOC will notify ALLTEL and IFN management that a cable cut has 
           occurred.

     D.    Disconnect from the electronics equipment (at both sites) all fibers 
                                                         ----
           associated with the cut cable.

     E.    Connect the OTDR to one of the transmit fibers at one location to
           scan the fiber to determine the approximate distance to the cable
                                                       --------
           cut.

     F.    Using the distance obtained above, consult the as-built drawings kept
                                                                           ----
           on hand at that site to geographically locate the cut.
           --------------------    --------------

     G.    If an OTDR is available at the equipment location on the other side
           of the cable cut, the Duty Man at that locations should also scan a
           transmit fiber to obtain a distance to the cable cut and should
           consult the as-built drawing file at his site to determine the
           geographic location of the cable cut. The information obtained at
           both sites should be compared to verify that the geographic location
           of the cable cut has been obtained with reasonable accuracy.

     H.    Notify the cable maintenance personnel via 2-way radio or mobile
           telephone of the approximate location of he cable cut as obtained
           from the OTDR scan(s). If the cable personnel have not already
           located the cable cut, these personnel should immediately report to
           that location. If two companies are involved, both companies'
                                                         ----
           personnel should report to that location and the "non-owner's crew"
           should assist the "owner's crew" as needed.


                                       3
<PAGE>
 
4.   The cable maintenance personnel should determine what caused the cable cut
     and should note the name and address of the responsible party if the damage
     is not due to "natural causes". This information should be provided to the
     AOC which will be forwarded to ALLTEL management, after the system has been
                                                       -----
     returned to service.

5.   It is important that communication be maintained between the cable
     maintenance personnel and at least one of the electronics sites on either
     side of the cable cut. This communication will be necessary to coordinate
     cable restoration and to conduct tests necessary to minimize splicing
     losses. It is possible that an individual may be required to man the
     maintenance radio base station of the company involved. This individual may
     be called upon to relay information obtained via 2-way radio or mobile
     telephone communications from the cable maintenance personnel to the Duty
     Man (or men) via land-line communications. The decision to assign a man to
     the radio base station is left to the judgment of each company's
     Maintenance Supervisor and/or Duty Man.

6.   It is the responsibility of the network control center to keep ALLTEL
     management and others informed of the ongoing status of the restoration
     effort.

7.   The cable maintenance personnel are to access the cable at the site of the
     cut and are to follow prescribed procedures to restore the cable. The
     transmit and receive fibers for the primary fiber pair should be restored
     first so that the system can be returned to service. The transmit and
     receive fibers of the standby pair should be restored next. This approach
     should minimize service outage time.

8.   While cable splicing is in progress, the output power levels for each
     transmit fiber should be measured with an Optical Power meter and then
     recorded. These readings should be made at each electronic site on either
     side of the cable break. As each fiber is restored, the receive power level
     should be measured with an Optical Power Meter and again recorded. The
     fiber loss derived from the above reading can then be compared to existing
     site records to assure that cable restoration has not resulted in
     unacceptable system operational levels.

9.   When service has been restored, the AOC will immediately notify ALLTEL, and
     Interstate FiberNet.

10.  The AOC, will insure that all alarms at all sites affected by the cable cut
     have been returned to their normal condition and that the overall system,
     from terminal to terminal, has been returned to normal service.

11.  After all restoration splicing is complete, the supervisor of the cable
     maintenance crew is to update the as-built drawings to indicate all
     technical information associated with the cable cut. This information
     should be forwarded to the AOC.

12.  All materials and supplies used during our restoration will be replaced as 
     soon as possible.

1.4 EMERGENCY RESTORATION

I    The ALLTEL Operation Center maintains and up-to-date emergency restoration 
     call out list and escalation list.

     A.  The AOC will monitor alarms 24 hours a day, 7 days a week.

     B.  The AOC provides a single point of contact for emergency restoration.

     C.  An up-to-date list of trained repair supervisors and craftsmen are kept
         in the AOC.

         1.  This list will prioritize the supervisor and craftsmen to be called
             first.

         2.  This list will also identify repair areas or exchanges and the 
                      supervisors/craftsmen responsible for those locations.

II.  Trained supervisors/craftsmen and emergency restoration equipment will be
     strategically located along the fiber route to enhance faster system
     restoration.

     A.  Appropriate vehicles and repair/restoration equipment are strategically
         located along the route.

     B.  Sufficient amounts of equipment will be located strategically along the
         route.

III. Emergency restoration cable coils will be prepared in advance and pre-
     established quantities of cable will be stored to handle extreme emergency
     situations.

     A.  Emergency restoration coils of not less than 100 meters in length and
         equipped with organizers and closures will be used for primary
         restoration.

     B.  Quantities of fiber cable of sufficient size and length will be
         maintained, as repair stock, to cover section replacements that
         are longer than previously prepared emergency restoration coils.

IV.  When emergency restoration splicing is completed with mechanical splicing
     connectors, the following are recommendations that should be considered
     when selecting a mechanical splice connector.

     A.  The connector should consistently make low loss splices of 0.5 db or 
         less.

                                       6

V.   Permanent repairs will be completed as soon as possible and will normally 
     begin immediately following emergency restoration.

     A.    Following the permanent repairs, maintenance personnel will complete 
           an outside plant system span test.

           1.    End-to-end attenuation measurements of each fiber will be
                 completed in both directions from FDP (Fiber Distribution
                 Panel) to FDP at either 1310nm and/or 1550nm wavelengths.

1.0 GENERAL

1.01 This document will provide direction and standardization in splicing 
procedures for fiber optic cable. All construction will be done in strict 
compliance with the 1996 National Electrical Safety Code and all other federal, 
state and local regulations.

1.02 This exhibit sets forth general principles of fiber optic cable 
construction, and incorporates comprehensive details and specifications 
concerning fiber optic cable construction contained the following practices:
ASP (ALLTEL System Practice) 290-350-456, ASP 290-350-455, ASP 290-400-605, ASP 
290-500-400, ASP 540-850-005, ASP 540-850-010, ASP 540-850-015, SRP (Southern 
Region Practice) 290-630-610 and SRP 93-2020.

2.0 GLASS FIBER SPECIFICATIONS

2.01 All glass fiber used in any fiber optic cable will adhere to the following
specifications. Specific circumstances may necessitate a variance from these 
perimeters. In these instances a case by case evaluation will be made.

            1.  Single mode fiber
            2.  8.3 micron core nominal
            3.  Cladding diameter 125 +/- 2 micron
            4.  Coated diameter 250 +/- 15 micron
            5.  Core eccentricity not more than 1.0 micron


                                       1
<PAGE>
 
           6.    Dispersion not to exceed 2.6 psec/nm-km @ 1310nm and typically 
                 less than 1 psec/nm-km @ 1550 nm.

           7.    Attenuation per fiber not to exceed 0.40db/Km @ 1310 nm 
                 0.30db/Km @ 1500 nm.

2.02 Copies of the manufacture's test results are to be retained and become part
of the as-built documentation.

3.0  BASIC SPLICING PROCEDURES

3.01 Each fiber will be tested at each splice and the results recorded on the 
form provided in Attachment I of Exhibit 3 . These forms will become part of the
                                        ---
as built documentation.

3.02 Splice cases will be standard manufactured Preformed stainless steel 
Fiberlign or injection-molded Coyote splice cases. Splice cases will be 
installed in accordance with the manufacture's recommended procedures. All 
splices will be protected fusion splices.

3.03 When the cable sheath contain armor, each sheath will be bonded to a #6 
insulated ground wire. Each sheath will be isolated from the others sheaths and 
the splice case. The #6 insulated ground wires will be connected to a driven 
ground rod that has a ground resistance reading of not more than 25 ohms.

3.04 Standard procedure for aerial or buried plant requires all splice cases to 
be at ground level in a Reltec OPFOBD7 cabinet. The cabinet will also contain 
storage for approximately 100' of cable. The stored cable will permit the case 
to be relocated to an environmentally controlled area for splicing.

3.05 In location where ground level facilities are not permitted, subsurface 
splices vaults will be placed. The vaults must permit ready access to the splice
case. This vault will also provide storage for cable which will permit the 
splice case to be relocated to an environmentally controlled area for splicing 
operations. Direct buried splices are not to be placed without approval of 
management.

4.0  CABLE SPECIFICATIONS:

4.01 Fiber optic cable for aerial, buried or underground construction will be 
single mode standard production cable, with a high or medium density 
polyethylene jacket. All cable will be filled or contain a water blocking 
compound. The fibers will be color coded with industry standard colors. The 
cable may be loose tube, central tube or ribbon type constructed. Armored cable 
will contain an overlapping coated steel armor. Metallic strength members are 
acceptable only in armored cable.

                                       2

<PAGE>
 
5.0  PLACEMENT OF AERIAL CABLE

5.01. Aerial splices will be brought down the pole and placed in a BPFOBD7
cabinet. If the cable sheath contains any metallic member it will be bonded to a
#6 ground wire and connected to a driven ground rod. Sufficient cable will be 
stored in the cabinet to allow the splice to be relocated to an environmentally 
controlled area for slicing.

5.02 A 3" drip loop will be placed in the fiber cable at each pole. Attached to 
the cable at the drip loop will be an identification tag stating the owner of 
the cable.

6.0 PLACEMENT OF DIRECT BURIED CABLE

6.01 Splices in direct buried plant will be brought to the surface and placed in
a BPFOBD7 cabinet. The armor and any metallic member in each sheath will be
bonded to an insulated #6 ground wire and connected to a driven ground rod in
the cabinet. Each sheath will be isolated from the others sheaths and the splice
case. The #6 insulated ground wires will be connected to a driven ground rod
that has a ground resistance reading of not more than 25 ohms. Sufficient cable
will be stored in the cabinet to allow the splice to be relocated to an
environmentally controlled area for splicing.

6.02 The buried cable will be placed at a minimum depth of 36" measured from the
top of the cable to the surface of the ground. Buried warning tape is to be 
placed at a depth of 18" to 24" below grade at the time of construction.

6.03 Warning signs will be located along the route, culverts and at road 
crossings. Signs will be placed at approximately quarter mile intervals and at 
other locations that are susceptible to excavation. Signs are to be tubular in 
design, providing 360 degrees visibility, and display the 1-800 call before you 
dig telephone number.

7.0 PLACEMENT OF UNDERGROUND DUCT CABLE

7.01 Cable may be placed in duct by pulling or blowing the cable into the duct. 
At no time should the pull on cable being placed in the duct exceed the 
recommended tensile load rating of the manufacturer, typically 600 pounds.

7.02 Cable placed in manholes will wrap the hole a minimum of two times to 
provide slack for restoration. The cable will be identified with a tag in each 
hole.

                                       3
<PAGE>
 
7.03 Splice cases located in manholes will be securely mounted on the cable 
racking and identified. Sufficient cable will be stored in the manhole to allow 
the splice to be relocated to an environmentally controlled area for spicing.

8.0 CABLES ENTERING BUILDINGS

8.01 Cables entering buildings will have two separate entrances where ever 
possible. The intent is to promote diverse routing at every opportunity.

8.02 The armor and any metallic members of any cable entering a building will be
severed and bonded with a #6 insulated ground wire at the first opportunity upon
entering the building. This will normally occur at the point the outside plant 
cables are spliced to the inside cables. This can be a splice case or a splice 
cabinet. The #6 ground wire will be bonded to the hot side of the single point 
MGN bar. Cables that do not contain metal and therefore do not require isolation
and grounding should be identified as non-metallic.

1.0 GENERAL

1.01 This practice will provide direction and standardization in splicing and 
acceptance of fiber optic cable. This practice sets the minimum standard tests 
that are to be performed during construction, acceptance and restoration. It 
does not limit testing to these tests if there is reason to suspect the presence
of a condition that would render a cable unserviceable.

1.02 The procedures are applicable to all aerial, buried, or underground fiber 
optic cable. These procedure will be the standard for the acceptance. All fiber 
optic cable, regardless of length, will pass the tests prescribed in this 
practice.

1.03 This practice also describes the tests that are required on existing cable 
that is being considered as feeder for digital loop carrier.

1.04 The performance of the tests and the recording of the test data will be the
responsibility of the engineering department. If independent contractors are 
used for construction the engineer and a representative of the contractor will 
perform the test jointly. The results of the tests will be recorded on the 
appropriate Southern Region Cable Acceptance form. The acceptance for fiber
optic cable is shown in Attachment I.

2.0 GENERAL SPLICING SPECIFICATIONS

2.01 All construction splicing will be protected fusion splices and all test 
results will be recorded. Individual splices should be evaluated with the OTDR 
during the actual splicing phase of the project. No splice should have a loss of
more than .1db. If .1db loss is not obtained after three (3) attempts, the 
splice may exceed the .1db loss


                                       1
<PAGE>
 
requirement but is not to exceed .5db. The engineer is to be consulted if more 
than .5db occurs. High losses can be the result of core mismatch, poor core 
concentricity or irregular core shape. These conditions are not likely to be 
corrected with repeated attempts at splicing. This condition is exceptional and 
should occur infrequently and only on single fibers in the slice. If difficulty 
is experienced in obtaining splices of .1db or less on all but an exceptional 
fiber, procedural or mechanical causes are to be suspected.

2.02 The splicing of different manufacturer's fiber can also result in 
difficulty in obtaining low loss splices. This is the result of inherent 
difference in the glass of the fiber. If this occurs, all of the fibers in the 
splice are usually affected. For this reason it is suggested not to mix cable 
from different manufacturers if possible.

2.03 Protected fusion splices are the first choice for restoration splicing. 
Mechanical splices may be utilized only for temporary restoration purposes when 
fusion capabilities are not available. All mechanical splices will be replaced
with protected fusion splices as soon as practical.

2.04 When circumstances do require the use of mechanical splices the splice loss
will not exceed .20 db insertion loss with a minimum reflective loss not less 
than 35.0 db.


3.0 OPTIC CABLE ACCEPTANCE-GENERAL

3.01 Fiber optic cable will pass the following acceptance test prior to being 
accepted and placed in service. Fiber optic cable has no length exceptions and 
all new cable will be tested. The test results will be recorded on the Southern 
Region Cable Acceptance-Fiber Optic form shown in Attachment I.


3.02 REQUIRED FIBER OPTIC CABLE TEST

        Armor to ground
        Armor bond continuity
        End to end OTDR traces
        End to end power meter reading


4.0 ARMOR TO GROUND TEST

4.01 The armor to ground test for buried fiber optic cable will be performed 
using a megohmmeter in a similar manner to that described for the shield to 
ground test used on

                                       2
<PAGE>
 
copper cable. A value of 161,000 ohm-kilometer should be considered the minimum 
acceptable value of the armor ground resistance.

4.02 For example, at 161,000 ohms per kilometer, for a 6KM (3.7 mile) fiber 
cable would be estimated at approximately 26,883 ohms. This is calculated by 
dividing 161,000 ohms by 6KM, the length for the estimated ohms resistance.

4.03 To obtain the actual value for the cable, the actual test set reading is 
multiplied by length of the cable. This value is then compared to the estimate 
to determine the acceptability of the cable. The actual results must exceed the 
estimated value.

4.04 The intent of testing the armor in the fiber cable is to ensure no damage 
was incurred during placement. If sheath damage did occur during placement the 
testing will show a ground fault.

4.05 To record the results of the armor to ground test the following information
is entered as shown in Attachment II. Enter N.A. if the cable is nonmetallic.

     1. Enter the work order number authorizing the cable construction.

     2. Enter the type, manufacture and number of fibers of the cable being 
     tested.

     3. Enter the exchange the cable is located.

     4. Enter the number of sheets needed to record the test data.

     5. Enter the pole or pedestal number where the test equipment is located to
     perform the test. If more sections of cable are tested than can be shown,
     go to a second sheet.

     6. Enter the pole or pedestal number that is at the far end of the section 
     of cable being tested.

     7. The megohms reading is entered in block number 7.

     8. Enter the actual date the test was performed.

     9. The name of the person performing the test is entered in block 9.

5.0  ARMOR BOND CONTINUITY TEST

                                       3

<PAGE>
 
5.01 The armor bond continuity test will be performed after the cable is in 
place and all splices are complete. In testing the armor bond continuity in 
fiber optic cable a VOLT-OHM meter will be used to read the resistance of the 
armor and check for opens.

5.02 To perform this test the far end of the cable armor is to be grounded. The 
near end will be isolated. Place the positive lead from the VOLT-OHM meter on 
the armor. The common lead is then grounded. The resulting reading should show 
very low resistance. Typical results for fiber cable are 33.6 ohms per KM for 
cable constructed with only metallic armor. If the cable also contains metallic 
strength members embedded in the sheath a resistance figure of 21.5 ohms per KM 
should be used. The actual reading will depend on the length of the cable.

5.03 To ensure the full length of the cable is being read, a second reading is 
taken with the far end ground isolated. The result should show an open, 
indicating that the ground that was read the first time was the far end ground.

5.04 If a fiber optic cable is made up of sections of armored and dielectric 
cable each of section of armored will need to be tested individually.

5.05 To record the results of the armor bond continuity test enter the following
information in blocks 10 through 14 as indicated in Attachment II. Dielectric 
cable will be indicated with N.A.

     10. Enter the pole or pedestal number where the test equipment is located 
     while performing the test. If more sections of cable are tested than can be
     shown go to a second sheet.

     11. Enter the pole or pedestal number that is at the far end of the section
     of cable being tested.

     12. Enter the result of the VOLT-OHM meter test as good or fail

     13. Enter the actual date the test was performed.

     14. Place the name of the person performing the test.

6.0  END TO END OTDR TRACES

6.01 Although traces are not an actual acceptance test, OTDR traces are required
final documents. A trace will be taken of each fiber from both directions. These
will serve as a permanent base line record for each fiber. The traces show the 
fiber attenuation,


                                       4
<PAGE>
 
splice loss, location of splices and overall length. A trace of each individual 
fiber is required.

6.02 OTDR traces are to be maintained as permanent record in each central office
in which the cable appears, the work order file and with the restoration kit. 
This information is invaluable in the event of restoration and is required in 
the SRP 290-630-610, Fiber Optic Emergency Restoration Guidelines.

6.03 The OTDR will be connected to each fiber through the patch panel. Consult 
the operator's manual for instructions. Each fiber trace should also indicate 
the location from which the trace was made and the number of the fiber.

6.04 The fact that OTDR traces were made is recorded on the acceptance form as 
indicated in Attachment II.

     15. Enter the central office where the OTDR is located during the test.

     16. Enter the date the traces were made.

     17. Enter the central office where the OTDR is located to perform the 
     traces for the direction opposite to that shown in block 15.

     18. Enter the date the traces were made.


7.0  END TO END POWER METER READING

7.01 The end to end loss of the fiber is the deciding factor in fiber optic 
cable acceptance. This test evaluates both the fiber and splices. The loss 
associated with individual splices is not a specific function of acceptance 
testing.

7.02 To accomplish the end-to-end loss test, a power meter and light source are 
used to determine the actual attenuation of the fiber and splices over its 
entire length. The source of the light can be the multiplexed equipment or a 
separate light source. Operator's manuals should be consulted for specific 
instructions.

7.03 To perform this test a known quantity of light is introduced into the fiber
with a light source. This is determined by using the power meter to read the 
output of the light source. The fiber is then connected to the light source. The
amount of light reaching the far end is then read with the same power meter. The
known source light figure is then subtracted from the reading taken at the far 
end with the power meter. The difference is the actual loss incurred in the 
entire length. All of the fibers will be tested.


                                       5
<PAGE>
 
7.04 This process is then repeated in the opposite direction. It is not unusual 
for readings taken from one direction to differ from readings taken in the 
opposite direction.

7.05 Compare the estimated loss on the loss budget provided by engineering to 
the results of the test. If the figures are within 10% plus or minus, the cable 
is acceptable. If a greater difference is found the transmission engineer should
be informed of the discrepancy. The cable will not be considered as accepted 
until the discrepancy is explained. The loss of the fiber and splices combined 
determine the acceptability of the cable.

7.06 The end-to-end power meter less test results will be recorded as indicated 
on Attachment II.

        19. Enter the central office or location were the light source is 
        located.

        20. Enter the central office or location that is the far end of the 
        cable being tested.

        21. Enter the number of the fiber. If a fiber cable is being tested that
        is larger than 16 fibers a second sheet is required.

        22. Enter the db reading of the light source. This should be a constant 
        for all the fiber tested from that location at that time.

        23. Enter the power meter reading at the far end.

        24. Enter the result of subtracting the source light from the end 
        reading.

        Blocks 25 through 30 reflect the similar information as 19 through 24
        but with readings from the opposite direction. This permits directional
        comparison of the same fiber.

        31. The engineer indicates the cable as being accepted or rejected.

        32. Enter the date of the final acceptance.

        33. Enter the name of the engineer accepting or rejecting the cable.

        34. Enter the name of the representative of construction who jointly 
        performed the tests.

7.07 The completed form is to be maintained in each central office in which the 
cable appears, the work order folder and with the restoration kit.

1.0 GENERAL

1.01 The following specifications define the minimum requirements for as-built 
documentation. Documentation will be exchanged by IFN and ALLTEL for their 
respective fiber facilities. These documents will be combined with the 
acceptance testing forms and any other pertinent information to serve as the 
source data during a restoration. Without accurate and detailed records of the 
plant as it was built, restoration activities will be greatly hampered.

2.0 BASIC INFORMATION

2.01 Basic as-built information will include the date of placement, size, type 
and manufacture of the fiber cable. Included with this will be the cable 
manufacture's reel test and all other acceptance test results.

3.0 FACILITIES DRAWINGS

3.01 Facility drawings will show the actual route, location and depth of the 
fiber cable as constructed. Details are to include road names, splice points, 
road crossings, conduit, sequential readings of the cable and any other 
specifics that will assist in any restoration activity.

4.0 TESTING AND ACCEPTANCE DOCUMENTS

4.01 Test and Acceptance Documents will include bi-directional OTDR traces and 
power meter readings, both at 1310 NM and 1550 NM, for each fiber.

                 connectors.

     III.  Certification for outside plant span acceptance and maintenance
           personnel will require making permanent documentation from OTDR
           readings and completing end-to-end attenuation measurements.
           
           A.    Create permanent records of span performance by printing hard
                 copies of DR traces (footprints) or by entering OTDR data into
                 an auxiliary personal computing program.
                 

           B.    Demonstrate the ability to properly complete end-to-end
                 attenuation measurements using 1310nm and 1550nm wavelength
                 sources and power meters.

     IV.   Initial certification will be completed before splicing begins.
           Additional certification on new products and procedures will be
           completed as required.

     1.2   ALARM REPORTING

     I.    Alarms from all IFN equipment locations will be received in the IFN
           Network Operations Center (NOC). The alarms will be sent via alarm
           sending devices from each site to the NOC in West Point, GA. (Note:
           IFN will require IFB lines into each site).

1.5  RESTORATION PROCEDURES

The following procedures will be followed when a fiber optic cable has been 
severed:

I.   The cable maintenance technicians should immediately obtain all necessary
     equipment and materials required to repair a cable cut from restoration
     stores and should report with those items as quickly as possible to the
     electronics equipment site nearest the suspected cable cut.

II.  The Duty Man should obtain all necessary test equipment, including Optical
     Time Domain Reflectometer (OTDR), DS-1 and DS-3 Bit Error Rate (BER) Test
     Sets, and Optical Power Meter, and should report (in a 2-way radio or
     mobile telephone equipped vehicle) to the electronics site. The IFN NOC
     will monitor and assist from West Point, Georgia.

III. Through on-site analysis of the local alarms displayed on the equipment at
     each site, the Duty Men are to confirm whether a cable cut has taken place.
     If a cable cut has not occurred, the cable maintenance personnel should be
     released and the Duty Men should take whatever action is required to
     correct the trouble, keeping their NOC informed at all times. If a cable
     cut has taken place, the Duty Men should coordinate their efforts to do the
     following:

     A.   Dispatch cable maintenance personnel (from each company if two 
                                                     ----
          companies are involved) to ride the cable route in an effort to 
          physically locate the point of the cable cut.

     B.   Alert the IFN NOC that a cable cut has occurred and provide expected 
          restoration time.

     C.   Upon discover, IFN NOC will notify ALLTEL and IFN management that a 
          cable cut has occurred.

     D.   Disconnect from the electronics equipment (at both sites) all fibers 
                                                        ----
          associated with the cut cable.

     E.   Connect the OTDR to one of the transmit fibers at one location to scan
          the fiber to determine the approximate distance to the cable cut.
                                                 --------
 
     F.   Using the distance obtained above, consult the as-built drawing kept 
                                                                          ----
          on hand at that site to geographically locate the cut.
          --------------------    --------------

     G.   If an OTDR is available at the equipment location on the other side of
          the cable cut, the Duty Man at that location should also scan a
          transmit fiber to obtain a


                                       6
<PAGE>
 
            distance to the cable cut and should consult the as-built drawing
            file at his site to determine the geographical location of the cable
            cut. The information obtained at both sites should be compared to
            verify that the geographic location of the cable cut has been
            obtained with reasonable accuracy.

      H.    Notify the cable maintenance personnel via 2-way radio or mobile
            telephone of the approximate location of the cable cut as obtained
            from the OTDR scan(s). If the cable personnel have not already
            located the cable cut, these personnel should immediately report to
            that location. If two companies are involved, both companies'
                                                          ----
            personnel should report to that location and the "non-owner's" crew
            should assist the "owner's" crew as needed.

IV.   The cable maintenance personnel should determine what caused the cable cut
      and should note the name, address and telephone number of the responsible
      party if the damage is not due to "natural causes." This information
      should be provided to IFN NOC which will be forwarded to ALLTEL and IFN
      management, after the system has been returned to service.
                  -----

V.    It is important that communication be maintained between the cable
      maintenance personnel and at last one of the electronics sites on either
      side of the cable cut. A conference bridge will be established (set up by
      IFN NOC). This communication will be necessary to coordinate cable
      restoration and to conduct tests necessary to minimize splicing losses. It
      is possible that an individual may be required to man the maintenance
      radio base station of the company involved. This individual may be called
      upon to relay information obtained via 2-way radio or mobile telephone
      communications from the cable maintenance personnel to the Duty Man (or
      men) via land-line communications. The decision to assign a man to the
      radio base station is left to the judgment of each company's Maintenance
      Supervisor and/or Duty Man.

VI.   It is the responsibility of the network control centers to keep ALLTEL and
      IFN management and others which are involved informed of the ongoing
      status of the restoration effort.

VII.  The cable maintenance personnel are to access the cable at the site of the
      cut and are to follow prescribed procedures to restore the cable. The
      transmit and receive fibers for the standby fiber pair should be restored
      first so that the system can be returned to service. The transmit and
      receive fibers of the primary pair should be restored next. Using this
      approach, traffic will be restored on standby fibers as the primary would
      have switched upon LOS (Loss-of-Signal). Primary traffic would then be
      locked over via NOC until the primary fibers are restored. This approach
      should minimize outage time.

VIII. While cable splicing is in progress, the output power levels for each
      transmit fiber should be measured with an Optical Power Meter and then
      recorded. These readings should be made at each electronic site on either
      side of the cable break. As each fiber is restored, the receive power
      level should be measured with an Optical Power Meter and again recorded.
      The fiber loss derived from the above reading can then be compared to
      existing site records to assure that cable restoration has not resulted in
      unacceptable system operational levels.

                                       7
<PAGE>
 
IX.  When service has been restored, the IFN NOC will immediately notify ALLTEL,
     and Interstate FiberNet. The time of restoral will serve to calculate the
     total outage time for IFN's customer service interruption credits. The IFN
     NOC will complete the trouble report at this time.

X.   The IFN NOC will insure that all alarms at all sites affected by the cable
     cut have been returned to their normal condition and that the overall
     system, from terminal to terminal, has been returned to normal service.

XI.  After all restoration splicing is complete, the supervisor of the cable
     maintenance crew is to update the as-built drawings to indicate all
     technical information associated with the cable cut. This information
     should be forwarded to the IFN NOC and forwarded to IFN Engineering.

XII. All materials and supplies used during our restorations will be replaced as
     soon as possible.


1.6  EMERGENCY RESTORATION

I.   The IFN NOC maintains and up-to-date emergency restoration call out list 
     and escalation list.

     A.   The IFN NOC will monitor alarms 24 hours a day, 7 days a week.

     B.   The IFN NOC provides a single point of contract for emergency 
          restoration.

     C.   An up-to-date list of certified repair supervisors and craftsmen are 
          kept in the IFN NOC.

          1.   This list will prioritize the supervisor and craftsmen to be 
               called first.

          2.   This list will also identify repair areas or exchanges and the 
               supervisors/craftsmen responsible for those locations.

II.  Supervisors/craftsmen and emergency restoration equipment will be
     strategically located along the fiber route to enhance faster system
     restoration.

     A.   Appropriate vehicles and repair/restoration equipment are 
          strategically located along the route.

     B.   Sufficient amounts of equipment will be located strategically along
          the route.

III. Emergency restoration cable coils will be prepared in advance and pre-
     established quantities of cable will be stored to handle extreme emergency
     situations.

     A.   Emergency restoration coils of not less than 100 meters in length and
          equipped with organizers and closures will be used for primary
          restoration.

                                       8
<PAGE>
 
     B.    Quantities of fiber cable of sufficient size and length will be
           maintained, as repair stock, to cover section replacements that are
           longer than previously prepared emergency restoration coils.

IV.  When emergency restoration splicing is completed with mechanical splicing
     connectors, the following are recommendations that should be considered
     when selecting a mechanical splice connector.

     A.    The connector should consistently make low loss splices of 0.5 db or
           less.
 
     B.    The reflection (return loss) should be greater than -35.0 db.

     C.    A connector that uses optical adhesive should be avoided. These
           connectors require additional time for complete assembly and the
           optical adhesive has a relatively short shelf life.

V.   Permanent repairs will be completed as soon as possible and will normally
     begin immediately following emergency restoration as coordinated through
     the NOC.

     A.    Following the permanent repairs, maintenance personnel will complete 
           an outside plant system span test. 
  
           1.    End-to-end attenuation measurements of each fiber will be
                 completed in both directions from FDP to FDP at either 1310 nm
                 and/or 1550 nm wavelengths.

           2.    New permanent records of span performance will be created by
                 printing hard copies of OTDR traces (footprints) or by entering
                 OTDR data into an auxiliary personal computing program.

           3.    All route diagrams or documentation containing pertinent
                 information for trouble locating must be updated and issued to
                 all essential field personnel.

           4.    Upon permanent repair, the new splice loss readings should be 
                 no greater than the temporary splice loss readings.

1.7  EMERGENCY POWER

     In case of commercial (AC) outage, power is restored by an on-site 
emergency generator. 

     In the event that a power company needs to be notified of the outage, the 
IFN NOC will do so. 

     In addition, voltage and specific gravity measurements are taken on the 
batteries at each site on a "per cell" basis monthly. Cell temperature 
measurements will take on a simple of cells at each site also. All of this 
information is recorded and is used to provided early detection of any battery 
problems.

                                       9
<PAGE>
 
1.8    CREDIT FOR OUTAGE PROCEDURES

       The IFN NOC will forward to management a copy of the Trouble Log which 
will detail not only the description of the trouble found and the action taken, 
but also include the time duration if an outage has occurred.

       The IFN management will provide the VP of Network Sales and VP of Finance
a report detailing the length of outage and circuits affected (by circuit
number) with a cross reference to IFN customer.  The VP of Network Sales and VP
of Finance will take the appropriate steps to issue outage credits to those
customers affected.

1.9    ROUTINE MAINTENANCE - FIBER OPTIC PLANT

I.     Optical power readings will be made on primary and standby systems at 
       terminal and repeater locations.

       A.   Record system transmit level.

       B.   Record system receive level.

       C.   Compare the scheduled maintenance span loss levels with the original
            acceptance readings.

II.    Scan each fiber with an OTDR at 1310 nm and/or 1500 nm wavelength and 
       print a hard copy of the trace or file the OTDR data into an auxiliary
       personal computing program.

       A.   Routes shorter than 20 kilometers between FDPs will be tested from
            only one FDP location.

       B.   Routes longer than 20 kilometers between FDPs will be tested from 
            both FDP locations.

       C.   Compare original acceptance trace to scheduled maintenance trace to
            detect any point anomalies or deteriorating fiber.

III.   Direct buried cables containing an armor will be evaluated to determine
       if sheath faults exist. All buried splices will be required to maintain
       cable shield (armor) isolation.  Each shield will connect to an above
       ground test station with an insulated #6 ground wire that is connected to
       a driven 5/8 inch x 8 foot ground rod.

       A.   Each section of fiber cable between splices will be isolated at the
            test stations and read for the presence of sheath faults.

       B.   Ground rods will be read to ensure a proper minimum resistance to
            the earth is achieved (25 ohms or less).

       This section identifies the Required Maintenance Items for IFN's 
       maintenance group.

       It has been determined that these items are necessary to provide proper
       maintenance for the network.

       This equipment would also be required to return the cable back to service
       in the event of a cable being cut.

       The Required Maintenance Items are listed in this section.

REQUIRED MAINTENANCE ITEMS

1.     Optical Time Domain Reflectometer (OTDR) capable of measurements at 1300
       and 1500 nm, printing hard copy of the trace.

2.     Continuously Variable Optical Attenuator.

3.     Optical Power Meter.

4.     Bit Error Rate (BER) Test Set: DS-1 and DS-3 levels.

5.     Spare fiber Optic Pigtails and Patch Cords.

6.     Spare Electronic Circuit Packs.


2.2    OUTSIDE PLANT CABLE AND SPAN ACCEPTANCE TESTING

       The following detailed procedures are necessary to document the integrity
on an outside plant fiber system.  This sequence of procedures begins with the
receipt of the first reel of cable and finishes with the end-to-end performance
testing of the span.

                                      11

<PAGE>
 
I.     Test every fiber of every incoming reel of fiber cable to determine 
       quality of the fiber and condition of the cable.

       A.   Couple a 1 kilometer spool of fiber into an OTDR operating at 1550
            nm wavelength and mechanically splice to each fiber to evaluate
            performance and optical length.

       B.   Print a hard copy of the OTDR trace or file the OTDR data into an
            auxiliary personal computer program.

       C.   Store the test data until the cable manufacturer's warranty has 
            lapsed.

II.    Create a fiber optic splice performance log that monitors fiber splicing
       results. splicing can be affected by poor quality fiber or malfunctioning
       splicing equipment.

       A.   The splice log should contain adequate information to properly 
            evaluate equipment and fiber performance at each splice point.

       B.   Read each fiber at each splice point from both FDP locations with an
            OTDR to ensure splice loss conforms to standards for splicing 
            operations.

       C.   Create a route diagram (as built sheet) or document containing 
            pertinent information for trouble locating.  This diagram should 
            include, but not be limited, to the following items:

            1.   List splice locations by pole, vault, manhole, line number,
                 street or road, etc.

            2.   Document the sequential meter markings on the sheath at each
                 splice location.

            3.   On lengthy buried routes sequential meter markings should be
                 obtained at frequent permanent locations, such as road 
                 crossings, storm culverts, pedestals or poles, etc.

            4.   The optical length to each splice location from each FDP should
                 be listed.  Ensure the correct index of refraction setting is 
                 used on the OTDR for the various glass manufacturers.

III.   Made end-to-end attenuation measurements from FDP to FDP, using a
       portable laser source and power meter.

       A.   Record measurements at both 1300 and 1550 nm wavelengths.

       B.   Compare these measurements to the calculated loss and notify the
            Transmission Engineering Group if notable differences exist.

IV.    Scan each fiber from both FDP locations with an OTDR at both 1300 and
       1550 nm wavelengths.

                                      12
<PAGE>

       A.   View each trace for any irregularities that do not appear to be
            normal scattering.

       B.   Create permanent records of span performance by printing hard copies
            of OTDR traces (footprints) or by entering OTDR data into an 
            auxiliary personal computing program.

2.4  FOR TESTING AND TURN-UP OF Ds-3'S

General

This procedure governs all aspects of the testing and turn-up of DS-3's.

This procedure supersedes all existing procedures.

Introduction

     Interstate FiberNet establishes this procedure as a subset of the IFN 
transmission network. This certification process is employed to verify that 
those transmission facilities meet the design and performance objectives set 
forth.

     This document describes the steps required of the IFN NOC and the field to 
certify any new or existing DS-3 turn-up.

     The certification process involves four general phases:

     1) A configuration review of the system that the DS-3 is transported.
     2) A 72-hour performance test of the entire DS-3 path.
     3) The analysis of the Service Order depicting routing information.
     4) Completing NOC Technician information on the Service Order.

     Phase one, three and four are performed by the IFN NOC. The performance 
test, phase two, set up by the field, in conjunction with the IFN NOC is 
conducted by field personnel under the direction of the IFN NOC. 

Performance Testing Process

     The method of testing utilizes the Bit Error Rate (BER) test set(s)
external to the facility under test.

     The only approved test for use are as follows:

     Fireberd 6000
     T-Berd 310
     T-Berd 209A

     All of these devices should have printers connected to them for test 
verification and the duration of the test is 72 consecutive hours.

<PAGE>
 
           2.    Cable ends will be insulated to prevent any possible short that
                 could occur by the unterminated cable. Insulation of cable will
                 consist of one of the following items: 1) electrical tape; 2)
                 wire nuts; or 3) heat shrink caps.

           3.    New ground wires can only be terminated on traffic-carrying
                 equipment (including DSX frames) during OFF HOURS unless the
                 respective NOC Network Manager has granted approval for this
                 work to be done during BUSY HOURS. These wires must have
                 previously been connected to a supplemental ground bus.

           4.    Old ground wires may not be removed until after the new wires 
                 have been terminated.

           5.    Isolation of DC return bus bars from distribution racks shall

     B.    Work which affects traffic channels shall be deterred until an OFF 
           HOURS period.

IV.  Equipment Installation
     ----------------------

     A.    All physical work on active equipment rack, cabling, etc., for power
           systems including chargers, batteries and UPS, will only be done
           during OFF HOURS.

     B.    Equipment other than that specified in the previous paragraph may be
           physically installed within a building, or shelter at any time,
           provided that there are no extraordinary circumstances which would
           jeopardize existing traffic carrying equipment by such installation.
           Such circumstances would include: (a) the movement of traffic-
           carrying equipment, (b) having to relocate active cables to
           accommodate such as installation, etc.

     C.    DC power, AC power and ground cables

           1.    These may be placed on cable ladders at any time.

                 on active equipment until OFF HOUR.


                                      23
<PAGE>
 
           3.    They may only be connected to active equipment racks, existing
                 battery plant, DC power board, or breaker panel during OFF
                 HOURS.

           4.    Cutting in new power on traffic carrying systems may only be 
                 done OFF HOURS.

           5.    Insulation of DC power cable will consist of one of the
                 following items: 1) electrical tape; 2) wire nuts; or 3) heat
                 shrink caps.

           6.    Fault alarm and coax cables may be run at any time during the
                 day. However, they may not be connected to any active equipment
                 until OFF HOURS.

           7.    When installing new equipment, ends of all cables that connect
                 to this equipment should be terminated on this equipment before
                 power is applied.

           8.    New equipment can only be powered up during OFF HOURS. Radio
                 equipment should be configured so that it cannot radiate when
                 powered up until the impact, if any, of the new equipment on
                 traffic-carrying channels can be determined.

           9.    Fiber optic cords may be run at any time as long as the 
                 existing traffic carrying fibers are not disturbed.

           10.   Work requiring traffic carrying fibers to be disturbed may only
                 be done during OFF HOURS.

V.   Outside Plant Relocation/Upgrade/Overbuild
     ------------------------------------------

     A.    Construction on operational fiber optic cable systems will generally
           be accomplished during BUSY HOURS. This is necessary due to the
           general requirements to obtain third party personnel, and the
           necessity for maximum sight visibility while working in confined
           right-of-way environments. In addition, this time frame affords
           increased visibility on collocated cable systems owned by other
           common carriers, electric utilities, etc.

     B.    Splicing work on fiber optic systems when DDN traffic is present will
           be accomplished under the following conditions.

           1.    When there is active DDN traffic in a tray the work will be
                 done during a DDN window. All traffic in that tray will be
                 rolled to another tray where possible. DDN window periods are
                 in

                                      24
<PAGE>
 
                 accordance with the published annual schedule. In addition, a 
                 DDN window must be requested at least 14 days in advance.

           2.    When there is DDN traffic, but not in a tray that is to be
                 worked in, work may be accomplished during a DDN Advisory which
                 is any day during OFF HOURS. A DDN Advisory must be requested
                 at least 48 hours in advance. All traffic will be removed from
                 the tray being worked on.

           3.    When working in a splice termination box (STB), to install or
                 replace pigtails or repair a bad splice, the above conditions
                 will apply.

     C.    All work on the fiber system containing live traffic will be 
           coordinated IN ADVANCE with the Network Manager at the IFN NOC.

           1.    Work will not start until clearance to commence is granted by 
                 the NOC.

           2.    The NOC will be required to be on line before starting work and
                 periodically during the work activities.

           3.    The NOC must be in direct contact with the field technical
                 personnel when cuts are made that may jeopardize traffic or
                 that could result in an actual outage.

           4.    Only one (1) fiber is to be cut at a time. After each cut is
                 made, system operation must be verified before another fiber
                 can be cut.

     D.    Prior to commencement of any work on fibers in splice trays or splice
           closures, all fibers associated with active systems must be labeled
           and verified.

           1.    Once this has been accomplished, traffic can be rolled from the
                 active tray or buffer.

           2.    Prior to cutting any fiber, the field technician will test the 
                 fiber to ensure traffic has been removed.

           3.    Traffic verification will be tested by placing a handheld fiber
                 traffic identifier or similar instrument on the pigtail or
                 fiber.

VI.  Filed System Test
     -----------------

     A.    There are a multitude of tasks associated with the commissioning of
           new and Overbuild equipment for revenue service. The functions noted
           below are those that are known to impact system performance and/or
           traffic.


                                      25

<PAGE>
 
1.   Testing at the DSX-3 frame or patch panel may be done any time, however, 
     connectivity cannot be disrupted until OFF HOURS.

2.   DS-3 patching will only be performed during OFF HOURS. DDN traffic can only
     be patched during a scheduled DDN maintenance window.

3.   Lightwave Distribution Frame (LDF) connections can be made any time to
     unused bulkhead connectors. Patch covers can only be disconnected from the
     frame during OFF HOURS. Traffic rolls from live pig-tails can only be
     performed during OFF HOURS.

4.   Turn power on and off inactive lightwave equipment racks during OFF HOURS 
     in they are in the same line up with active equipment.

5.   Protection switch Differential Absolute Delay Equalization (DADE) or 
     equivalent will be done during OFF HOURS.

6.   Any work which prevents a traffic carrying channel from switching to 
     protect will be done OFF HOURS.

7.   Overbuilds or reconfiguration of active traffic carrying common equipment 
     such as protection switches can only be done OFF HOURS.

8.   Over-path testing should be accomplished after the effect of the new 
     equipment on the existing system performance has been verified.

9.   Turning up on new channels should be done during OFF HOURS initially, if no
     degradations are noted, then work on new or overbuild channels can proceed
     at any time except where restricted elsewhere.

10.  Before any work is accomplished on overbuild channels, red tape will be
     placed on all traffic-carrying equipment in the overbuild lineup, to
     prevent accidental tampering with active equipment.

11.  Physical connections of temporary "cutover equipment" in preparation for a
     system change-out/upgrade must be done OFF HOURS unless the associated work
     could endanger employee/contractor safety. In such cases, secure approval
     in advance for BUSY HOURS.

12.  Electronic switching of a fiber optic channel may be done during OFF HOURS,
     after coordinating with the NOC. No more than two

                                      26
<PAGE>
 
                  switches each, up and back may occur without prior DDN
                  coordination.

            13.   Rollover of traffic on fiber optic systems to a spare fiber 
                  path in order that an active fiber pair or active lightwave
                  equipment can be worked on must be done during OFF HOURS. 
                  This applies whether the rollover is done at the DA-3 or 
                  optical level. A DDN maintenance window is required for 
                  systems carrying DDN traffic.

      B.    Prior to accepting a site for service initiation, IFN requires a 
            site walk through by IFN Operations personnel and a 72-hour test on 
            the new system, printed and provided to IFN Operations.

VII.  General Notifications of Work Activity in the Area
      --------------------------------------------------

      A.    System reliability requirements dictate that companies/personnel 
            planning any work activity which is not directly related to the 
            network but which could have an adverse affect in the event of a 
            mishap must meet advance reporting requirements as follows:
            
            1.     For non-recurring work- on or around structures, building,
                   equipment, etc. which are part of the fiber optic network -
                   Notify the NOC at least 72 hours in advance and provide a 
                   schedule of the planned activity(ies) and a full
                   scope/explanation of the work to be performed.

                               CARRIER AGREEMENT

                             TERMS  AND CONDITIONS

     This Carrier Agreement  (the "Agreement") is between MCI TELECOMMUNICATIONS
CORPORATION ("MCI") and ASSOCIATED COMMUNICATIONS COMPANIES OF AMERICA (ACCA)
("Customer"), an association of carriers which are subject to the Communications
Act of 1934, as amended, with offices located at 111 Congress Avenue, Suite
3000, Austin, Texas 78701.

1.   Scope of Agreement.
     -------------------

     (a)  A Member of ACCA shall be referred to herein as ("Member(s)"). A list
          of said Members is attached hereto as Exhibit A. Each Member must be a
          signatory to this Agreement in order to receive the benefit of this
          Agreement. New Members of ACCA shall be permitted to become a
          signatory and receive the benefits of this Agreement with the written
          consent of MCI, which consent shall not be unreasonably withheld.

     (b)  MCI shall provide to Customer certain specified domestic interstate
          service(s), international services, and intrastate common carriage
          service (s). For domestic interstate and international services, this
          Agreement incorporates by reference the terms of MCI Tariff FCC No. 1
          ("Tariff"), which is on file with the Federal Communications
          Commission and which may be modified from time to time by MCI in
          accordance with law and thereby affect the service(s) furnished
          Customer, except that the following terms and conditions shall
          supplement or, to the extent inconsistent, supersede Tariff terms and
          conditions and shall remain in effect throughout the Service Term. For
          intrastate services, this Agreement incorporates by reference each
          applicable state tariff filed by MCI, which may be modified by MCI
          from time to time, and thereby affect the service(s) furnished
          Customer. This Agreement is entered pursuant to Section 211(a) of the
          Communications Act of 1934.

     (c)  Capitalized terms not otherwise defined in this Agreement shall
          have the meanings assigned to them in the Tariff.

2.   Monthly Commitment.
     -------------------

     (a)  During each monthly billing period of the Service Term (as defined in
          Paragraph 15 below), Customer's Monthly Usage shall equal or exceed
          [______________________________] per month ("Monthly Commitment").

                               MCI CONFIDENTIAL
<PAGE>
 
          As a part of Customer's Monthly Commitment, each Member shall have the
          individual Monthly Usage Commitments associated with each Member's
          name in Exhibit A (Member Monthly Commitment (s). Monthly Usage shall
          mean Customer's usage of: (i) MCI Carrier Network Service, MCI Carrier
          Operator Service, domestic interstate MCI PRISM I Service, MCI 800 DAL
          Service, MCI Feature Card Service, MCI Directory Assistance, MCI
          Terrestrial Digital Service 1.5 ("TDS 1.5"), MCI Terrestrial Digital
          Service-45 ("TDS-45") and MCI Digital Private Line Service ("DS-0
          Service")) (hereinafter "MCI Services") at the rates in Paragraphs 4
          and 7 below or if no rates for MCI Services listed herein are set
          forth, then at standard tariffed rates after application of tariffed
          discounts, but not including any applicable taxes (and gross receipts
          taxes) and tax-related surcharges on MCI Services; (ii) International
          PRISM I Service and International 800 DAL Service at the rates in
          Exhibit E (hereinafter "International Services"); and (iii) 
          intrastate MCI Services at standard tariffed rates after application
          of any applicable tariffed discounts (hereinafter "Intrastate
          Services").  For these services listed above, the charges for
          Telefonica Larga Distancia de'Puerto Rico, Inc. (including those under
          an agreement between TLD and MCI dated June 9, 1994) shall count.

     (b)  If Customer's Monthly Usage is less than the Monthly Commitment in a
          month, for that month: (i) Customer will pay the Customer's actual
          combined monthly recurring and usage charges for MCI services at
          standard MCI tariffed rates (however, Members will continue to be
          billed at the rates contained in this Agreement); and (ii) an
          underutilization charge (which Customer agrees is reasonable) equal to
          [______] of the difference between the Monthly Commitment
          and Customer's Monthly Usage. All underutilization charges shall be
          billed both to ACCA and to Members. ACCA shall be responsible for
          paying all such underutilization charges. However, Customer's
          liability under this Paragraph 2(b) shall be limited to the amount of
          the Monthly Commitment. Members shall not be liable for
          underutilization in any month that the overall Monthly Usage equals or
          exceeds the Monthly Commitment.

     (c)  If in any monthly billing period during the Service Term, MCI
          overbills any or all ACCA Members for services and subsequently
          corrects that billing, reducing the amount of the bill(s) and if
          Customer reduced its usage of MCI services as a direct result of such
          overbilling, and if the usage reduction was reasonably calculated,
          based on the overbilling, to maintain Customer's Monthly

                               MCI CONFIDENTIAL
                                      -2-
<PAGE>
 
          Commitment as required in Paragraph 2 (a), MCI shall not assess
          underutilization charges for any month in which underutilization
          charges are due until sixty (60) days from the date that MCI provides
          rebill information that reduces the actual monthly usage below the
          Monthly Commitment.

     (d)  At such time as Customer believes that it has met the [___________
          ___________________________] contract minimum usage requirement as
          contained in Paragraph 15(b), Customer may inform MCI in writing that
          it has projected the attainment of its minimum usage requirement. MCI
          and Customer will, within ten (10) days, jointly agree in writing as
          to the actual total usage as of a date certain, and MCI shall not
          assess Customer underutilization charges for the difference between
          the agreed upon actual total usage and a lesser amount that results
          from a subsequent MCI rebilling, should a subsequent rebilling reduce
          the actual total amount.

3.   Carrier Network Service.
     ------------------------

     (a)  In order to be eligible to purchase MCI Carrier Network Service:

          (1)  Except in areas where service origination is not available from
               access providers via a Carrier Identification Code ("CIC"),
               Members must originate all traffic via Member's own CIC. Member
               shall pay all charges associated with the installation of
               Member's CIC in all Local Exchange Carrier ("LEC") end offices.

          (2)  Customer shall comply with Section 64.1100 of the FCC's Rules and
               Regulations, as well as other applicable law or regulation
               pertaining to the sale and delivery of telecommunications
               service(s) to Member's enduser. MCI shall not be liable to
               Member's enduser for any claim, liability or expense asserted by
               those customers in connection with Member's sale or delivery of
               such service(s), including the unauthorized conversion of a
               customer's Primary Interexchange Carrier ("PIC") designation to
               Member's CIC. In addition, Members shall indemnify and hold MCI
               harmless from any actions, claims, suits or damages arising out
               of Member's violation or alleged violation of any FCC or other
               applicable law or state regulation, and Customer shall pay all
               reasonable attorney fees and

                               MCI CONFIDENTIAL
                                      -3-
<PAGE>
 
               costs incurred by MCI in connection with such actions, claims,
               suits or damages.

          (3)  Customer agrees that it or its Members will obtain and maintain
               any and all approvals to resell MCI Carrier Network Service
               hereunder from the FCC, including requirements imposed by Section
               214 of the Communications Act of 1934, as amended, and state
               regulatory bodies.

          (4)  Customer or its Members agree to sell and bill MCI Carrier
               Network Service under its own name, identity or mark, and Member
               further agrees not to reference MCI's name or marks in any
               context involving its furnishing of service(s) to the public
               except as provided herein. Member agrees to abide by the "Use of
               Name Guidelines" contained in Exhibit F hereto. In reselling MCI
               Services under this Agreement, Member will observe the highest .
               standard of integrity and fair dealing with members of the
               public. Furthermore, Member agrees to indemnify MCI for any
               actions, claims, suits or damages arising out of any allegation
               that if proved would cause Member to be in breach of this
               provision and Member shall also pay all reasonable attorney's
               fees and costs incurred by MCI due to any actions, claims, suits
               or damages arising out of such allegation.

          (5)  Except as set forth in Paragraph 12(e) herein, Member shall have
               sole responsibility for interacting with its endusers in all
               matters pertaining to service, including the placing and handling
               of service orders, service installation, operation and
               termination, dispute handling and resolution, and billing and
               collection matters. MCI shall incur no obligation, nor shall it
               be deemed to have any obligation, to interact with Member's
               endusers for any reason or purpose. Member shall cooperate with
               MCI as necessary to address and resolve service-related issues
               and problems and shall impose upon its endusers an obligation to
               cooperate, with Member in addressing and resolving service-
               related issues and problems.

     (b)  Without limitation, if any Member fails to abide by the requirements
          in Paragraphs 3(a)1, (a)3), (a)4), or any requirement in 3(a)2
          excluding the unauthorized conversion of customer's PIC, MCI shall
          provide Member written notice, and if Member fails to cure the default
          in fifteen (15) days after receipt of written notice, MCI

                               MCI CONFIDENTIAL
                                      -4-
<PAGE>
 
          shall have the right to terminate the Carrier Network Services
          provided in this Agreement to said Member.

          If any Member fails to abide by the requirement in Paragraph 3(a)2 as
          it relates to the unauthorized conversion of a customer's PIC, the
          following shall apply:

          Upon the second (2nd) finding by a court, the FCC or state commission
          of an unauthorized conversion of a Member's enduser's PIC, such
          finding shall be regarded as a material breach of the Carrier Network
          Services portion of the Agreement, and MCI may terminate the Carrier
          Network Services, upon five (5) days' written notice to Member. In
          such case, MCI will provide Member up to six (6) months to convert
          such traffic to another vendor; provided that however, during the six
          (6) month period, upon a third (3rd) finding by a court, the FCC or
          state commission of an unauthorized conversion of a Member's endusers
          PIC, MCI may terminate the Carrier Network Services on five (5)
          business days written notice for such Member.

     (c)  Customer agrees that MCI may use the National Leads Information System
          ("NLIS") or an appropriate internal MCI system to determine Working
          Telephone Number ("WTN") historical data regarding MCI and non-MCI
          PICs and Customer and its enduser understand that such systems are not
          error free. MCI will not be liable to Members for errors made in
          determining WTN in reliance on information contained in NLIS or
          internal MCI systems.

     (d)  Customer understands and accepts that, as part of MCI's normal
          business policy and practices and its obligations under law, MCI will
          engage in extensive marketing efforts in attempt to sell its services
          to the public and that such efforts will result in active competition
          with Customer for the business of users who are Customer's customers
          or prospects. Accordingly, Customer further understands and accepts
          that such competition by MCI is in all respects fair and proper and
          that Customer shall not complain, nor be heard to complain, of
          business lost to MCI. Under no circumstance shall any inference be
          derived that MCI's entry into this Agreement with Customer means that
          MCI will restrict its efforts to compete against Customer in any way.

     (e)  Customer understands and accepts that no fiduciary relationship arises
          by virtue of this Agreement and that, accordingly, MCI incurs none of
          the obligations that arise in such relationship as an incident of its

                               MCI CONFIDENTIAL
                                      -5-
<PAGE>
 
          fulfilling its obligations under this Agreement. Further, Customer
          understands and accepts that MCI is not an insurer of profits for
          Customer, nor does MCI guarantee the success of Customer's business as
          a result of Customer's receipt of service(s) under this Agreement.

     (f)  Member agrees that if its enduser makes a call using 1OXXX access
          (utilizing Member's CIC), from an ANI which Member did not provide to
          MCI to enter into MCI's Billing and Order Entry systems, MCI will bill
          the call through the LEC at MCI tariffed rates, and MCI's name will
          appear as the service provider on the LEC invoice. Furthermore,
          Members agree its sales and marketing channels will only market 1OXXX
          access as a dialing option from ANIs that the enduser had PIC'd to the
          Member's CIC, in areas where the Member's CIC is pointed to MCI for
          termination

                    Customer or its Member's termination liability provided for
                    in Paragraph 17 of this Agreement.

               (b)  Customer or its Members are entitled to subscribe to and

          (exclusive of usage in Paragraph 7(h), switched 56Kbps service) during
          September, October and November 1995 shall be added together and
          divided by three (3) . The credit amount shall be applied to the
          January, 1996 invoice and the credit shall not exceed [_________]
          Dollars [__________]. When referenced above, actual monthly usage
          billing shall exclude MCI services where no rates are listed in this
          Agreement for the MCI service and where Members pay standard tariffed
          rates after application of tariffed discounts.

     (b)  For the second credit, Customer's actual monthly usage billing
          (exclusive of usage in Paragraph 7 (h), switched 56Kbps service)
          during August, September, October and November 1996 shall be added
          together and divided by four (4). The credit amount shall be applied
          to the December 1996 invoice and shall not exceed [_________] Dollars
          [__________]; provided that however, if the Agreement continues in
          effect for at least twenty (20) months the credit amount limit shall
          be [___________] Dollars [__________] and the additional credit amount
          above [_________] Dollars [__________] shall be applied in the twenty-
          first (21st) month. When referenced above, actual monthly usage
          billing shall exclude MCI services where no rates are listed in this
          Agreement for the MCI service

                               MCI CONFIDENTIAL
                                     -28-
<PAGE>
 
          and where Members pay standard tariffed rates after application of
          tariffed discounts.

     (c)  If Customer submits in writing to MCI before the conclusion of the
          seventeenth (17th) month that Customer will not terminate the
          Agreement until after the twenty-first (21st) month, and if Customer's
          total actual monthly usage billing exceeds [_____________] Dollars
          [___________], the credit limit in Paragraph 10(a) will be increased
          to [___________] Dollars [__________] from [_________] Dollars
          [__________], and the credit limit in Paragraph 10(b) shall be
          increased to [___________] Dollars [__________].

     (d)  The credits shall be applied to Customer's net domestic interstate
          usage charges (exclusive of applicable taxes, surcharges, and pass-
          through access/egress charges) for MCI services hereunder.

     (e)  To determine if Customer has met the [__________________] Dollar
          [____________] amount  in  Paragraph  15(b), Customer's usage
          (exclusive of usage in Paragraph 7(h)) shall be calculated after
          deduction of the credits provided above.

11.  Security.
     ---------

     Customer shall, as a condition precedent to receipt of MCI Services
     hereunder, provide within ten (10) days of executing this Agreement an
     Irrevocable Letter of Credit in a form acceptable to MCI in an amount equal
     to [___________________] Dollars [________].  This Letter of Credit shall
     not exceed [___________________] Dollars [________] except if the payment
     terms in Section 12 are not met or if the financial conditions of Customer
     or any of its Members materially changes.  If the Letter of Credit is not
     received by MCI within sixty (60) days of the date of execution of this
     Agreement by the parties, Customer shall pay to MCI [_____________] percent
     [____] of Customer's total net invoice for each month (or a pro rata
     portion for a partial month) that the Letter of Credit is delinquent. The
     letter of credit shall be attached hereto and incorporated by reference.
     Customer shall continuously renew the letter of credit as necessary to keep
     it in effect during the service term.  Customer shall continuously revise
     this letter of credit so that it is equal to one (1) week average billing
     for all Members over the previous two (2) months. Nothing contained herein
     shall limit or be interpreted to limit MCI's right, as provided  for in
     Section B-7.04 of MCI Tariff F.C.C. No. 1, to require, in MCI's sole
     discretion, alternative  or  additional  security  from  Customer,  and
     Customer's failure or refusal to provide such alternative or 

                               MCI CONFIDENTIAL
                                     -29-
<PAGE>
 
     additional security upon MCI's reasonable request therefor may result in
     the cancellation of this Agreement and Customer's service for cause
     pursuant to Section B-11.01 of the Tariff. Any requirement for additional
     surety shall be based upon a review of Customer's payment history under the
     terms of this Agreement and upon a reasonable evaluation of Customer's
     financial condition. The security arrangements provided for hereunder shall
     survive the expiration of the service term, as defined herein, and shall
     remain in effect so long as Customer remains a user of MCI service(s).


12.  Payment.
     --------

     (a)  MCI shall invoice each Member separately. Each Member of ACCA shall
          prepay to MCI an estimated monthly payment by wire transfer by the
          first (1st) day of each month beginning in the first (1st) month after
          the execution date hereof,  in the amount of the previous month's
          invoice.  For example, January's usage shall be paid on January 1
          based on the previous month's invoice. Members who are not current MCI
          Customers shall pay as follows:

          o    For their first month, fifty percent (50%) of their estimated
               invoice, such estimated invoice amount to be mutually agreed by
               MCI and new Member, shall be prepaid (i.e., January's prepayment
               shall be paid on January 1).

          o    For their second (2nd) month and continuing thereafter, the new
               Member shall prepay based on one hundred percent (100%) of the
               prior month's invoice less any disputed amounts agreed upon in
               writing by MCI. MCI will not unreasonably withhold such
               agreement.

          Within ten (10) days of the date of MCI's invoice, MCI and Customer
          will reconcile the prepayment with the MCI invoice amount for such
          month.  MCI shall credit any prepayment amount in excess of the MCI
          invoice amount for such month on the next available invoice.
          Immediately after reconciliation, Customer shall pay MCI any amount
          the prepayment was less than the MCI invoice amount for such month.

     (b)  If Customer has met its Monthly Commitment during a month, and if a
          Member pays for the month's services in advance by the first (1st) of
          that month, then such Member shall receive an additional [___________
          ___] percent [____] discount during such month as identified below in
          (c). If a Member fails to prepay as required in

          of that month, then the Member shall not be entitled to the [_______
          _______] percent [____] discount and shall pay [___________________]
          percent [____] interest per month on all amounts in arrears.

          In the event that an ACCA Member fails to prepay as required, MCI
          shall notify ACCA in writing at an address provided by ACCA and ACCA
          shall by the eighth (8th) day of that month either: 1) allow MCI to
          draw from the LOC the sums necessary to make one quarter (1/4) of the
          prepayment that is in arrears, or 2) pay the prepayment directly to
          MCI. If the prepayment is made through the LOC or by ACCA, MCI may, at
          its discretion, immediately remove the Member as a party to and
          beneficiary of this Agreement and/or terminate all MCI Service to such
          Member. Upon such removal as a Member and/or termination of services,
          the Member shall be charged Tariff rates for all services received
          after such removal or termination and the collection of amounts due
          and owing will be per tariff. ACCA shall have no further
          responsibility for any payments for any Member in default of its
          obligations contained in Paragraphs 12 (a) and 12 (b). If such
          removed or terminated Member qualifies under MCI's surety
          requirements, MCI may offer such Member MCI's then current "carrier
          program" pricing at the term and volume commitment levels agreed upon.

     (c)  The additional discount in 12(b) above shall be applied only after
          application of all other discounts and credits that Customer may be
          entitled to under MCI's tariffs and this Agreement. The amount of the
          discount shall be calculated by determining [______________] percent
          [____] of that Member's monthly recurring and usage charges for MCI
          services in this Agreement. The discount amount shall be applied as a
          credit to such Member's interstate monthly recurring and usage
          charges.

     (d)  The termination of any Member pursuant to paragraph (b) above shall
          not affect Customer's Monthly Commitment.

     (e)  In the event Customer fails to pay MCI invoiced amounts as required
          and MCI notifies Member that Member's endusers service will be
          terminated for non-payment, Member agrees to notify, jointly with MCI,
          the Member's endusers of the potential disruption of service, by the
          mailing of a letter, signed by Member, to each enduser, containing the
          following language. The mailing of a letter applies only where: i) the
          enduser is still Member's enduser and MCI is the underlying carrier;
          ii)

               customers will terminate within two (2) weeks of the date of this
               Letter. This letter is being sent to you as a courtesy so that
               you can make the necessary arrangements so that you do not
               experience a disruption of your communications services. You have
               a choice of long distance carriers. If you have any questions,
               please contact Member (representative and telephone number) or
               your local telephone company.

               Sincerely,

               further [_______________________] Dollars [______] to secure the

               authority is limited to resolution of disputes under this
               Agreement, MCI Tariff FCC No. 1, and any other Documents signed
               by both parties. The arbitrator's decision shall follow the plain
               meaning of the relevant documents, and shall be final. In no

                         MCI CARRIER OPERATOR SERVICES


Customer is interested in buying MCI Carrier Operator Services for resale and 
MCI is interested in providing such services to Customer. In order to accomplish
those purposes the parties hereby agree as follows:

1.  Operator Services:
    -----------------

    (a) MCI shall provide Customer with MCI Carrier Operator Services as such
        service is delineated in applicable tariffs, including MCI Tariff FCC
        No. 1 (the "Tariff") and, except as provided herein, at the rates
        contained in the Tariff.

    (b) "Operator Service Calls" mean long distance calls dialed with the 0+,
        01+ or 00- dialing pattern (and excluding calls dialed with the 950-XXXX
        and 800 dialing patterns).

    (c) Customer shall not use any service mark or trademark of MCI.

    (d) Call Originating Identification Information. MCI must receive electronic
        -------------------------------------------
        call origination identification ANI information for each call carried
        hereunder. If the Originating Site uses Feature Group D local access
        service, the required call origination identification information is
        automatically supplied by the local exchange company. If the Originating
        Site uses a type of local access service other than Feature Group D
        local access service, the Originating Site shall cause electronic call
        origination identification information (in a form acceptable to MCI) to
        be supplied to MCI at the initiation of each call.

    (e) Emergency Calls.
        ---------------

        (1) Each Originating Site shall configure its system so that 911
            emergency calls, where available, and similar emergency calls, will
            be automatically routed to the appropriate party or clearing house
            without the intervention of MCI. Emergency calls which do reach a
            MCI operator shall be handled in accordance with MCI standard
            operating procedures.

        (2) If Member or MCI provides an emergency number database, Member

                  MCI FEATURE CARD FRAUD DETECTION PROCEDURES

                       ==================================

All calling card calls will be validated by MCI to permit only those calls 
authorized or facilitated by Member or legitimate card holders.  MCI will, at 
the direction of Member, preclude all calls utilizing expired or terminated 
calling card numbers compared against an authorized list provided by Member and 
will be responsible for all fraudulent use, unauthorized use, misuse, or abuse 
of calling cards occurring after MCI receives actual notice of the expiration or
termination of a calling card or receives specifically detailed written 
notification concerning any card which has been lost, stolen, compromised or 
which Member has reason to believe is or may be used fraudulently.  MCI will 
deactivate a calling card within four (4) hours of receipt by MCI's Consumer 
Markets Fraud Detection of a request by Customer.

In addition, all calling card calls will be monitored by MCI for fraudulent use,
unauthorized use, misuse or abuse on a twenty four (24) hour a day, seven (7) 
days a week basis.  MCI shall establish fraud prevention, detection and 
minimization procedures so that fraudulent use arising from lost or stolen 
calling cards and potential disruption to authorized card holders will be 
minimized.

MCI will not hold the Member responsible for "service fraud" associated with the
unauthorized use of an MCI calling card.  "Service fraud" can best be described 
as unauthorized use of an MCI calling card following the involuntary theft or 
loss of a card which was not intentionally facilitated or impliedly authorized 
by Customer or an authorized user.  "Service fraud" often follows the theft of a
wallet, purse or briefcase, or sometimes is the result of "shoulder surfing" 
(thieves observing/recording authorization codes) which occurs at payphones 
located in airports, bus terminals, train stations and the like.  MCI shall not 
be responsible for losses caused by fraudulent information submitted by a card 
holder in subscribing for calling card services or for usage which was 
intentionally facilitated or impliedly authorized by an authorized user.

In the event that MCI is unable to contact Member of suspected abuse of the 
calling card, in order to minimize potential abuse, MCI will deactivate any 
calling card which has exceeded established fraud detection parameters or which 
MCI has reason to believe is or may be used fraudulently.

Resellers MAY NOT make in words or in substance the following statements:

     "Network services provided by MCI"
     "Authorized/Endorsed/Sponsored/Approved by MCI"
     "Authorized Provider of MCI Services"
     "Affiliate, or partner, or co-marketer with MCI"

     If resellers wish to make any reference to MCI, they may ONLY make the 
following declarative statement:

     "Reseller's services utilize the MCI network"

     However, the following conditions apply to this statement:

     .  This statement may not be used in ANY manner that is likely to create
     confusion or to give the impression that MCI sponsors, endorses, or is in
     any way affiliated with the Reseller

     .  This statement may only be used as a declarative statement in any
     printed or oral communication and may not be used as a headline or in any
     advertising slogan or banner. In order to use this statement, the
     Reseller's company name must appear or be verbalized prominently in the

                             TERMS AND CONDITIONS

1. DEFINITIONS. "You" and "Your" refers to Customer. "MCI" refers to MCI
Telecommunications Corporation. "HyperStream/SM/ Frame Relay" or "HSFR" means
MCI's packet-oriented frame-based data networking service, as described in MCI
Tariff F.C.C. No.1 ("Tariff"), as revised from time to time

2  SERVICE TERMS.


2.1. This HyperStream/SM/ Frame Relay Enrollment Form and Agreement incorporates
     by reference the Tariff, as it may be amended or modified from time to time
     (collectively, the "Agreement"). In the event of any inconsistency between
     the terms of the Tariff and this Enrollment Form and Agreement, the Tariff
     shall be deemed controlling. MCI will furnish the service to Customer
     pursuant to the terms of this Enrollment Form and Agreement and the Tariff,
     and any other applicable interstate, international or state tariffs, of MCI
     and its affiliates.


2.2. With the exception of revisions of the Tariff made in accordance with
     applicable law, this Agreement may only be amended in writing signed by
     authorized representatives of the parties.


3. RATES AND CHARGES. Customer will pay standard rates as set forth in the
Tariff for MCI HyperStream/SM/ Frame Relay service, including but not limited to
access charges, installation charges, reconfiguration charges, monthly recurring
port and permanent virtual circuit ("PVC") charges. MCI charges which contribute
to satisfaction of any Monthly Minimum are set forth in the Tariff ("Qualifying
Volume"). MCI charges eligible for discounts are also set forth in the Tariff
("Eligible Volume").

3.1  Month-to-Month.

     If Customer selected a Month-to-Month plan, Customer shall pay standard
     month-to-month tariffed rates without a term or volume commitment, except
     Customer shall be liable for satisfying any monthly PVC minimum
     requirements.

3.2  HyperStream/SM/ Frame Relay Network Pricing Plan ("HPP").


     3.2.1  Term and Monthly Minimum Commitments.

            If Customer selected an HPP, in lieu of any other tariffed term plan
            (except Access Pricing Plans), Customer agrees to use services
            pursuant to this Agreement for a period of years, as indicated above
            ("Term"). Customer further agrees to purchase at least the Monthly
            Minimum, before application of any discounts, of HSFR recurring port
            and PVC charges for services pursuant to the Tariff, during each
            month of the Term. At the completion of each year in a multi-year
            Term, Customer may increase its Monthly Minimum. Following
            execution by Customer of an amendment increasing its Monthly
            Minimum, the terms and conditions of this Agreement will then apply
            at the new, higher Monthly Minimum. After expiration of the initial
            Term, this Agreement shall automatically renew for a period of one
            (1) year, unless MCI receives written notice of termination from
            Customer at least thirty (30) days prior to expiration of the
            initial Term, or unless Customer has met the requirements set forth
            under "Termination without Liability." Upon expiration of the
            renewal period, Customer will receive standard tariffed rates for
            month-to-month HSFR service, until such time as either party
            provides the other with at least thirty (30) days written notice of
            termination. The term of an associated Access Pricing plan ("APP")
            is independent of the HPP term.

     3.2.2  Underutilization Liability.

            Commencing with the fourth (4th) full monthly billing period
            following commencement of the Term, if Customer fails to satisfy its
            Monthly Minimum during any month of the Term, Customer shall pay an
            underutilization charge equal to one hundred percent (100%) of the
            difference between Customer's Qualifying Volume during such month
            and Customer's Monthly Minimum.

     3.2.3  Early Termination Liability.

            If Customer terminates this Agreement prior to expiration of the
            Term or prior to expiration of any renewal period, other than
            pursuant to the terms set forth below for "Termination without
            Liability", Customer shall pay early termination charges, equal to a
            portion of the total HPP discounts received during the Term prior to
            termination, based upon the year in which Customer terminates.

     3.2.4  Termination Without Liability.

            Customer may discontinue this Agreement without liability, except
            for charges incurred prior to termination, provided Customer
            executes a new HyperStream/SM/ Frame Relay agreement with a greater
            or equal term and a greater or equal monthly volume commitment.

4. PROMOTIONS. Customer will receive HSFR promotions indicated with an "X"
below, pursuant to the eligibility requirements, availability, and other terms
and conditions as set forth in the Tariff. In the event a promotion is
selected for which Customer is ineligible, or in the event an unacceptable
combination of promotions is selected, such promotion selections will be
invalid and this Agreement shall remain in full force and effect without regard
to any invalid promotion selections.

_________   HyperStream/SM/ Frame Relay Trial Promotion. Customer shall pay
            rates and charges pursuant to the terms and conditions of the Tariff
            during the first sixty (60) days following implementation of the
            first service element ("Trial Period"), provided Customer has not
            received MCI HSFR service during the previous 365 days and Customer
            satisfies any other eligibility requirements set forth in the Tariff
            Upon expiration of the Trial Period, Customer will automatically be
            enrolled in an MCI HyperStream/SM/ Frame Relay agreement for HSFR
            service on a monthly-month basis pursuant to the terms and
            conditions of the Tariff, unless Customer executes an MCI
            HyperStream/SM/ Frame Relay agreement with term and monthly volume
            commitments prior to expiration of the Trial Period, or unless
            Customer provides written notice of termination to MCI prior to
            expiration of the Trial Period. The HSFR Trial Promotion may not be
            used concurrently with any other HyperStream Promotional Offering
            but, upon expiration of the Trial Period, Customer may be eligible
            to receive the benefits of one or more HyperStream Promotion
            Offerings.

            HyperStream/SM/ Frame Relay service at any time during the preceding
            365 days, except pursuant to the Trial Promotion, are ineligible for
            this promotion)

                  MCI FEATURE CARD FRAUD DETECTION PROCEDURES
                      ===================================

All calling card calls will be validated by MCI to permit only those calls
authorized or facilitated by Associated Communications Companies of America or
legitimate card holders. MCI will, at the direction of Member, preclude all
calls utilizing expired or terminated calling card numbers compared against an
authorized list provided by Member and will be responsible for all fraudulent
use, unauthorized use, misuse, or abuse of calling cards occurring after MCI
receives actual notice of the expiration or termination of a calling card or
receives specifically detailed written notification concerning any card which
has been lost, stolen, compromised or which Member has reason to believe is or
may be used fraudulently. MCI will deactivate a calling card within four (4)
hours of receipt by MCI's Consumer Markets Fraud Detection of a request by
Member.

In addition, all calling card calls will be monitored by MCI for fraudulent use,
unauthorized use, misuse or abuse on a twenty four (24) hour a day, seven (7)
days a week basis. MCI shall establish fraud prevention, detection and
minimization procedures so that fraudulent use arising from lost or stolen
calling cards and potential disruption to authorized card holders will be
minimized.

MCI will not hold the Member responsible for "service fraud" associated with the
unauthorized use of an MCI calling card. "Service fraud" can best be described
as unauthorized use of an MCI calling card following the involuntary theft or
loss of a card which was not intentionally facilitated or impliedly authorized
by Member or an authorized user. "Service fraud" often follows the theft of a
wallet, purse or briefcase, or sometimes is the result of "shoulder surfing"
(thieves observing/recording authorization codes) which occurs at payphones
located in airports, bus terminals, train stations and the like. MCI shall not
be responsible for losses caused by fraudulent information submitted by a card
holder in subscribing for calling card services or for usage which was
intentionally facilitated or impliedly authorized by an authorized user.

In the event that MCI is unable to contact Member of suspected abuse of the
calling card, in order to minimize potential abuse, MCI will deactivate any
calling card which has exceeded established fraud detection parameters or which
MCI has reason to believe is or may be used fraudulently.

          --------------------
services are hereinafter collectively referred to as the "SERVICES".

          A.   "ANCILLARY SERVICES" consist of calling card operator assisted
calls and calling card traffic generated via the Codes which access the
following Allnet special features: teleconferencing, voice mail, Allnet Call
Delivery(R), Allnet InfoReach(R), SpeedLink(R), Option USA(R) and such other

          C.   "800 PIN SERVICE" consists of inbound SWITCHED SERVICES combined
with a PIN 800 Number which is accessed via four digit personal identificiation
numbers ("PIN NUMBERS") assigned by Customer to End-Users. The use of the PIN
Numbers with a PIN 800 Number permits multiple End-Users to utilize the same 800
telephone number on an individual basis. 800 DIRECTORY ASSISTANCE is not

          D.   "DEDICATED SERVICES" consist of (i) switched outbound long
distance traffic delivered to an Allnet Point of Presence ("POP") via dedicated
facilities and terminated over the Allnet network, and (ii) switched inbound 800
traffic generated via 800 Numbers which traffic originates on the Allnet network
and is terminated by Allnet onto Customer's or a End-User's dedicated
facilities.

          E.   "DIRECTORY ASSISTANCE SERVICES" consist of calls made by End-
Users to directory providers for assistance in locating a non-800 Number. "800
DIRECTORY ASSISTANCE" consists of calls made to directory providers for
assistance in locating an Allnet 800 Number.

          F.   "INBOUND SERVICES" shall collectively refer to inbound traffic
under the Dedicated Services, Switched Services and 800 PIN Services.

          G.   "INTERNATIONAL SERVICES" consist of international traffic
generated via the Dedicated Services, Switched Services or Calling Card
Services.

Allnet network.

2.   SERVICES AVAILABILITY.
     ----------------------

     2.1  Commencing on such dates after the Effective Date as may be mutually
agreed upon by the parties in writing, Allnet shall provide the Services
selected by Customer in those areas where Allnet in its sole discretion
determines the Services to be available. Allnet shall provide the Services in
accordance with the terms and conditions of service set forth in the applicable
Allnet federal and state tariffs, which are incorporated herein by reference
(the "TARIFF"). An excerpted copy of the Tariff is attached as Exhibit 2.1 and
made a part hereof.

     2.2  Customer understands and agrees that the Services do not include
value-added services that Allnet makes available to its customer base, such as
without limitation, Allnet ESP(R) reports, and that Allnet is not obligated to
provide End-Users with such value-added services.  Customer further understands
and agrees that the 800 PIN Service is not available to commercial End-Users.

                                       4
<PAGE>
 
     2.3  "OPERATOR SERVICES" are defined to be calls made via 00, 0- or 0+
calling that require the assistance of an operator to complete, such as but not
limited to, collect calls and bill-to-a-third-number calls. Operator Services
specifically exclude calling card operator assistance calls which are deemed to
be part of the Calling Card Services. "700/900 NETWORK CALLS" are those calls
made to various information providers utilizing telephone numbers with 700 or
900 dialing sequences. Operator Services and 700/900 network calls are not
included in the Services, but may be made available to End-Users via the Allnet
network. If Operator Services or 700/900 network calls are utilized by End-
Users, such calls shall be billed to End-Users at standard Allnet charges either
directly by Allnet or through its billing agents. Allnet shall not bill Customer
for the Operator Services or 700/900 network calls utilized by End-Users and any
revenues collected by Allnet for such Services and calls shall be retained
solely by Allnet. Allnet reserves the right to revise its rates for Operator
Services and 700/900 network calls at any time.

     2.4  Customer understands and agrees that End-Users whose telephone lines
are presubscribed to Allnet may be requested to call 1-700-555-4141 to confirm
their long distance carrier and that they will hear a recording identifying
Allnet as their long distance carrier.  If requested by Customer, Allnet shall
provide Customer with an available 700 number (1-700-555-XXXX) and a recorded
message that identifies Customer as the carrier. Customer's request and message
selection shall be made in writing on the Subscription Checklist submitted by
Customer when it first orders the Switched Services. Allnet shall make such 700
number available for Customer's use within fifteen Business Days after receipt
of said Subscription Checklist.

3.   RATES FOR THE SERVICES.
     ----------------------

     3.1  Customer shall purchase and pay for the Services at the rates set
forth in Exhibit 3.1 attached hereto and made part hereof.

4.   CALL DETAIL RECORDS.
     -------------------

     4.1  Customer shall have the option of receiving call detail records for
usage of the Services ("CDR") on (i) a monthly basis, (ii) a pre-bill run basis
(approximately six times per week), or (iii) no CDR at all. Customer may also
elect both options (i) and (ii), as further detailed below.

          A.   If Customer elects option (i), then on or about the fifth
Business Day following the end of a Billing Cycle, Allnet shall deposit with an
overnight delivery service for delivery to Customer a magnetic tape containing
CDR for the Services in the modified CARE format set forth in Exhibit 4.1 A.
attached hereto and made a part hereof (the "CDR TAPE"). The CDR Tapes will rate
the Services at the standard Allnet rates in effect at the time the Services
were provided. Customer shall pay a one-time CDR

                                       5
<PAGE>
 
Tape set up charge of [_____], plus [_____] per month. Software modifications to
the CDR Tape format requested by Customer are subject to Allnet approval and
will be invoiced to Customer at [_____] per hour, per programmer.

          B.   If Customer elects option (ii) above, then for each pre-bill
computer run performed by Allnet (generally pre-bill runs are performed by
Allnet six days per week) Allnet shall deliver the CDR by electronic data
exchange ("ELECTRONIC EXCHANGE") to either (i) Customer's designated mainframe
computer via the IBM Information Network ("IIN") via Network Data Mover ("NDM"),
or (ii) dedicated personal computer via Procomm+ software. The CDR transfers via
Electronic Exchange are initiated by Allnet and generally run during the evening
or early morning hours. Customer shall pay a one-time Electronic Exchange set up
charge of [_______], plus a monthly recurring charge of [_____]. Provided that
Customer is not in default hereunder, the [_______] set up charge shall be
credited to Customer after the Minimum Charge becomes effective. Further,
Customer shall be responsible for all transmission charges together with the
cost of hardware and software necessary at its location for use of IIN, NDM or
Procomm+, which hardware and software shall comply with the formats and
technical specifications that Allnet from time to time may promulgate. The
current Procomm+ format is set forth in Exhibit 4.1 A.

          C.   Customer shall select the applicable option or options at the
time it submits its first Subscription Checklist to Allnet. If Customer elects
both options 4.1 A. (i) and (ii), the individual set up charges and the monthly
recurring charges for both options shall be applicable. Customer may cancel an
option at any time on thirty days written notice. Customer may change an
existing option or select a new option at any time upon written notice and
payment to Allnet of the applicable set up charge. Changes or new selections
shall not be effective any earlier than the second Billing Cycle following the
date of the receipt of payment for the applicable set up charge.

     4.2  Customer shall have the affirmative obligation of providing written
notice of any inaccuracies in Customer Invoices within sixty Business Days after
receipt. In the event that Customer does not report an inaccuracy concerning a
Customer Invoice within said sixty Business Day period, Customer shall be deemed
to have waived its right to contest accuracy of the billing and deemed to have
agreed that the Allnet billing system inputs and outputs, including without
limitation, the CDR and answer supervision, are accurate and final. If an
alleged inaccuracy is brought to the attention of Allnet within said twenty
Business Day period and such inaccuracy is verified by Allnet to its reasonable
satisfaction, Allnet shall credit future Customer Invoices to reflect such
verified inaccuracy. Allnet represents that the billing system inputs and
outputs used for the Services will be substantially the same used by Allnet for
its other customers utilizing services similar to those provided to Customer
hereunder.

                                       6
<PAGE>
 
     4.3  Customer agrees that, other than for one minute call rounding, it
shall not charge End-Users utilizing any of the Services for more minutes of
Services' usage than is contained in the CDR provided by Allnet to Customer.

5.   FORECASTS; ORDER PROCESSING.
     ----------------------------

     5.1  Customer shall not be obligated to subscribe to all of the Services
being made available by Allnet hereunder. Requests for subscription to any of
the Services must be made by Customer at least thirty days prior to the desired
date of activation. At such time as Allnet executes this Agreement and returns a
copy to Customer, Allnet shall supply Customer with a subscription checklist and
information sheet that must be completed by Customer each time it requests
subscription to a new Service (the "SUBSCRIPTION CHECKLIST"). In addition to the
Subscription Checklist, Customer shall provide Allnet with a forecast covering a
good faith estimate of the monthly traffic volume and distribution for the
ordered Services/800 Number for the three calendar month period following the
desired activation date. The forecast shall be in the format attached hereto as
Exhibit 5.1 and made a part hereof. Each forecast shall be revised by Customer
at least thirty days prior to the expiration of each three calendar month
period. Within ten Business Days of receiving a forecast or revised forecast,
Allnet shall provide written acceptance or rejection of the forecast, in whole
or in part. Failure by Allnet to accept or reject a forecast within said ten
Business Day period shall not be deemed an acceptance of the forecast, unless
Allnet thereafter accepts orders for the Services/800 Number covered by the
forecast. If Customer exceeds a forecast accepted by Allnet, then Allnet shall
have the right to cease accepting all orders for the under-forecasted
Services/800 Number for such period of time as Allnet deems necessary, in its
sole discretion.

     5.2  At the time Customer submits its first Subscription Checklist to
Allnet, Customer shall select one of the options set forth below as the media by
which it will transmit to Allnet orders for the Services. Orders shall be
transmitted in the modified CARE format of Exhibit 4.1 A.

          A.   Magnetic tape in the format set forth in Exhibit 4.1 A.

          B.   Electronic Exchange via NDM.

          C.   Electronic Exchange via Procomm+.

Notwithstanding the foregoing options, if Customer has elected Electronic
Exchange for receiving CDR, then Customer shall be deemed to have selected
either option B. or C. above, whichever is applicable, for the purposes of this
Subsection 5.2.

     5.3  At the time Customer submits an order for the Services, Customer shall
furnish Allnet, via the applicable media hereunder, 

                                       7
<PAGE>
 
with the name, billing and service addresses and ANI of each applicable End-User
(the "END-USER INFORMATION"). The End-User Information is required for local
exchange carrier ("LEC") account set-up, normal call processing and handling NXX
level customer service. The End-User Information shall be deemed to be
Customer's Proprietary Information in accordance with Section 13.

     5.4  Allnet shall use its best efforts to activate Codes and End-User ANIs
in accordance with the following time frames:

          A.   Codes for existing End-User ANIs shall be activated within five
Business Days of receipt by Allnet of complete and accurate End-User
Information. Codes requested with End-User ANI orders will be activated when the
ANI is activated. If the End-User Information submitted by Customer is
incomplete or inaccurate, Allnet shall return the same to Customer for
correction and resubmission.

          B.   Customer understands and agrees that activation of End-User ANIs
is contingent on the End-User Information associated with such ANIs complying
with LEC established criteria. Assuming receipt of properly formatted End-User
Information that complies with said LEC established criteria, ANIs will
generally be activated within ten Business Days of receipt by Allnet of such 
End-User Information. If the End-User Information does not comply with said LEC
criteria, Allnet shall attempt to correct non-complying End-User Information to
the extent Allnet is able to do so ("ERROR CORRECTION"). If Allnet is unable to
perform Error Correction within a reasonable period of time not to exceed ten
Business Days after receipt of non-complying End-User Information, it shall
resubmit the non-complying End-User Information to Customer for Customer's
correction and resubmission.

          C.   Subject to the provisions of subparagraph D. below, once each
calendar month Allnet shall provide Customer with a written report detailing
moves, adds and terminations for End-User ANIs ("ANI INFORMATION"). If Customer
has elected to receive CDR via Electronic Exchange, then the ANI Information
shall be transmitted via Electronic Exchange, rather than by a written report.

          D.   If 10% or more of the aggregate End-User Information submitted by
Customer in any calendar month fails to comply with the aforesaid LEC criteria,
Allnet shall have the right in its sole discretion to cease providing Error
Correction and/or ANI Information and require Customer to perform both
functions. If Allnet ceases providing Error Correction and/or ANI Information
pursuant to the preceding sentence and Customer requests Allnet to reinstate
either or both, then Allnet may require Customer to provide an Allnet training
session covering compliance with LEC criteria to appropriate Customer personnel.
Such training shall be at a location designated by Customer and Customer shall
pay Allnet a training fee of $25.00 per hour for the trainer, plus the trainer's
travel, lodging and ancillary expenses.

                                       8
<PAGE>
 
     5.5  Notwithstanding the order transmission media selected pursuant to
Subsection 5.2, until such time as Allnet determines in its sole discretion that
Electronic Exchange and/or magnetic tape processing is available for the
reservation or ordering of 800 Numbers (and informs Customer of such
availability), orders for activation or reservation of 800 Numbers shall be by
facsimile and subject to the following.

          A.   Subject to (i) the Guidelines, (ii) delays attributable to other
carriers, RespOrgs or the SMS 800 Database, and (iii) Subsections 5.1, 5.6 and
7.1, Allnet/Carrier/Customer 800 Numbers shall be activated and confirmed by
Allnet within two Business Days of receipt by Allnet of a proper order in
accordance with the order processing requirements set forth below. If the order
submitted is not in compliance with said processing requirements, Allnet shall
return the same to Customer for correction and resubmission.

               (i)    Orders shall be submitted to Allnet via facsimile using
the form attached hereto as Exhibit 5.5 (i) and made a part hereof, and shall
include: (a) a letter of authorization in the format attached hereto as Exhibit
5.5 (i(a)) and made a part hereof, if Allnet is being appointed as the RespOrg,
and (b) the End-User Information for each 800 Number, including the ANI
translation for each 800 Number.

               (ii)   If Allnet is requested to reserve an 800 Number from the
SMS 800 Database on behalf of Customer, then Customer shall make such request
via facsimile using the form attached hereto as Exhibit 5.5 (ii) and made a part
hereof. Allnet shall fulfill up to 10 such reservation requests per calendar
month at no charge. Additional requests each calendar month shall be charged to
Customer at a cost of [_____] for every additional 100 requests or fraction
thereof. Allnet shall provide Customer with the status of its request (either
confirm reservation or indicate unavailability) via facsimile within two
Business Days of its receipt of the request. VERBAL REQUESTS FOR RESERVATIONS
WILL NOT BE ACCEPTED OR HONORED BY ALLNET.

               (iii)  If Allnet has reserved an 800 Number for Customer and
Customer does not order activation of the reserved number in accordance with
item (i) above within ten Business Days from the date of Allnet confirmation of
the reservation, the reserved number shall be assigned to the Allnet pool of 800
numbers and shall be available to Allnet for its or its other customers'
reservation and use. CUSTOMER UNDERSTANDS AND AGREES THAT CUSTOMER SHALL BE
RESPONSIBLE FOR ALL DAMAGES AND CLAIMS IN THE EVENT CUSTOMER AS8IGNS A RESERVED
800 NUMBER TO AN END-USER WITHOUT HAVING TIMELY ORDERED ACTIVATION OF SUCH 800
NUMBER WITH ALLNET AND SUCH 800 NUMBER IS ASSIGNED BY ALLNET TO A THIRD PARTY.
CUSTOMER AGREES TO DEFEND, INDEMNIFY AND HOLD ALLNET HARMLESS FROM ANY CLAIMS
AND COSTS (INCLUDING ATTORNEY FEES) RELATING TO THE ASSIGNMENT OF SUCH 800
NUMBER.

                                       9
<PAGE>
 
     B.   Subject to Subsections 5.1, 5.6 and 7.1, initial PIN 800 Number set up
shall be implemented within fifteen Business Days of receipt by Allnet of
complete and accurate End-User Information (including the applicable PIN
Number(s)). PIN Numbers must be numeric characters; "0000" is not available as a
PIN Number. For adding or deleting a PIN Number to an existing PIN 800 Number
the time frame shall be two Business Days after receipt by Allnet of Customer's
request for the addition or deletion. If the End-User Information submitted by
Customer is incomplete or inaccurate, Allnet shall return the same to Customer
for correction and resubmission.

     C.   The Allnet facsimile numbers and contact persons to be used for 800
Number reservations shall be 313-746-1433, Attention: Tonya Henderson; and for
800 Number orders shall be 313-647-2439, Attention: Mark Choroba. The Customer
facsimile number and contact person to be used for said purposes shall be
_______________, Attention:__________________. Either party may change its
respective facsimile number or contact person upon prior written notice to the
other party.

     5.6  In the event the traffic volume of ANIs, Codes or 800 Numbers ordered
onto the Allnet network by Customer is such that Allnet determines, in its sole
discretion, that a delay in processing orders is required, Allnet shall have the
right to temporarily delay order processing for such period of time as Allnet
deems necessary in its sole discretion. Any such delays shall not, however,
adversely impact Customer for the purpose of determining whether Customer has
met any minimum usage requirements hereunder. Allnet agrees to adjust the time
frames for said requirements to reflect such delays.

6.   CALLING CARD REQUIREMENTS.
     -------------------------

     6.1  Upon Customer's submission of a Subscription Checklist for the Calling
Card Services, Allnet shall commence the implementation of a Customer unique 800
gateway number for use of the Calling Card Services by End-Users (the "GENERIC
PROGRAM"). The Generic Program shall be subject to the Calling Card Surcharge,
but shall not be subject to the minimums set forth in Subsection 6.4. Allnet
shall make the unique gateway number available to Customer within thirty
Business Days after the date of receipt of the applicable Subscription
Checklist.

     6.2  Customer shall have the option of selecting a customized program for
the Calling Card Services that would include a Customer unique 800 gateway
number and specially recorded voice and operator scripting (the "CUSTOM
PROGRAM"). Upon submission by Customer of a Subscription Checklist for the
Custom Program selecting either option (i) or (ii) set forth below, Allnet shall
commence the process of developing the Custom Program. The two options, one of
which must be selected on the Subscription Checklist, are as follows: (i) paying
an initial customization fee of [________] to Allnet, or (ii) in lieu of such
payment, agreeing to meet the minimums set forth in Subsection 6.4. If Customer

                                       10
<PAGE>
 
selects option (i), but fails to timely pay the Customer Invoice listing the
[________] fee, Customer shall be deemed to have selected option (ii) above.
Subject to the written approval by Allnet of the customization specifications,
Allnet shall make the Custom Program available to Customer within forty-five
Business Days after the date of such written approval by Allnet. The unique 800
gateway number will be available for use with the Calling Card Services, but the
specially recorded voice and operator scripting will only be available for the
Allnet SpeedLink(R) special feature and the calling card operator assistance
function. The other Allnet calling card special features will identify Allnet or
another third party vendor as the provider of such features.

     6.3  After the Generic and/or Custom Program has been implemented, upon
receipt of Customer's order and the End-User Information sent via the applicable
media hereunder for the assignment of Codes, Allnet shall assign the Codes to
Customer for issuance to End-Users, subject to the following. Customer shall be
responsible for all costs associated with the design, production and
distribution of all calling cards to be issued to End-Users. Allnet reserves the
right, in its reasonable business judgment, to limit the number of Codes it
assigns to Customer. CUSTOMER ACKNOWLEDGES AND AGREES THAT ONCE ALLNET ASSIGNS
THE CODES TO CUSTOMER, THE CODES WILL BE ACTIVE AND CUSTOMER FURTHER AGREES THAT
IT SHALL BE RESPONSIBLE FOR (I) ALL CHARGES ASSOCIATED WITH THE USAGE OF THE
CODES ASSIGNED TO CUSTOMER HEREUNDER, INCLUDING WITHOUT LIMITATION, CHARGES FOR
CALL ABUSE, AND (II) ALL CLAIMS BY THIRD PARTIES, INCLUDING END-USERS,
ASSOCIATED WITH THE CODES ASSIGNED TO CUSTOMER HEREUNDER, INCLUDING WITHOUT
LIMITATION, CLAIMS REGARDING CALL ABUSE, REGARDLESS OF WHETHER OR NOT CUSTOMER
ISSUES SUCH CODES TO END-USERS.

     6.4  Excepting situations in which Customer has paid the [________]
customization fee pursuant to Subsection 6.2, if Customer has subscribed to the
Custom Program, Customer shall generate the following minimums in gross charges
(tariffed charges prior to available discounts) for usage of the Calling Card
Services as supported by the CDR for such Services.

          A.   [________] per month commencing with the sixth full month
following the month in which the Custom Program is made available to Customer.

          B.   [________] per month commencing with the twelfth full month
following the month in which the Custom Program is made available to Customer.

          C.   [________] per month commencing with the eighteenth full month
following the month in which the Custom Program is made available to Customer.

          D.   If any of the foregoing applicable monthly minimums are not
timely met, Customer shall have the option of paying either (i) a make up to
minimum charge of the difference between the applicable monthly minimum set
forth above and the actual 

                                       11
<PAGE>
 
gross charges for the Calling Card Services for each month in which the
applicable minimum is not met, or (ii) the [________] customization fee.
Customer shall make its election, and if it elects option (ii), Customer shall
pay the [________] customization fee so that it is received by Allnet within
fifteen Business Days following the date of written notice from Allnet that
Customer did not attain the applicable minimum. If Customer elects option (i),
then option (ii) shall no longer be available to Customer at any time and Allnet
shall add the appropriate make up to minimum charge to Customer Invoices for
each month in which the applicable minimum is not met for the remaining term of
this Agreement. If Customer elects option (ii), and timely makes its payment to
Allnet of the [________], Customer shall have no further obligations with
respect to the above minimums.

          E.   If Customer has subscribed to the Custom Program and elected to
be subject to the above minimums rather than pay the [________] customization
fee and this Agreement is terminated prior to the time the minimum under A.
above becomes effective (other than termination by Customer for an uncured
breach by Allnet), Customer agrees that it shall be liable for and pay to Allnet
the [________] customization fee.

7.   800 NUMBER REQUIREMENTS.
     -----------------------

     ALL 800 NUMBERS.
     ---------------

     7.1  A.   In order to protect the integrity of its network, Allnet may
without liability temporarily block any 800 Number having usage surges.  Allnet
agrees to use reasonable efforts to promptly notify Customer after such blockage
has occurred.

          B.   If usage of an 800 Number impacts Allnet in such a manner that
the unbillable (non-completed) calls for such 800 Number in any month are
greater than 5% of the billable (completed) calls for such 800 Number in that
month, Allnet may, in its sole discretion, charge Customer a non-discountable
$0.50 charge for each unbillable call in that month.

          C.   CUSTOMER AGREES THAT IT SHALL BE RESPONSIBLE FOR (I) ALL CHARGES
FOR USAGE OF 800 NUMBERS, AND (II) ALL CLAIMS BY THIRD PARTIES, INCLUDING END-
USERS, RELATED TO 800 NUMBERS, INCLUDING WITHOUT LIMITATION, CLAIMS REGARDING
CALL ABUSE, REGARDLESS OF WHETHER OR NOT CUSTOMER ASSIGNS ANY 800 NUMBERS TO 
END-USERS.

     7.2  Customer understands and agrees that call duration for 800 Number
calls are measured at (i) time-point ("TP") 7 minus TP6 for the Switched
Services and for inbound Dedicated Services traffic terminated to a End-User's
dedicated facilities, and (ii) TP7 minus TP1 for all call attempts for inbound

     ALLNET/CARRIER/CUSTOMER 800 NUMBERS.
     ------------------------------------

     7.3  At Customer's written request and to the extent available to Allnet,
Canadian origination will be available for Allnet 800 Numbers. Due to the fact
that Canadian origination is provided through an arrangement with third parties,
Allnet does not guarantee the availability or continuing availability of
Canadian origination. Customer shall inform End-Users in writing of this fact
prior to or at the time of Customer's sale of Canadian origination. Allnet shall
provide Customer with prompt written notice if Canadian origination becomes
unavailable.

     7.4  At Customer's written request and to the extent available to Allnet,
800 Directory Assistance will be available for Allnet 800 Numbers at a charge of
$15.00 per month per Allnet 800 Number requested to be listed with 800 Directory
Assistance. Due to the fact that 800 Directory Assistance is provided through an
arrangement with a third party, the provision of 800 Directory Assistance by
Allnet shall be subject to the policies and procedures promulgated from time to
time by such third party. Customer understands that any Allnet 800 Number listed
with 800 Directory Assistance is not published in any written directory, but is
only available on a call-in basis. Customer shall inform End-Users in writing of
this fact prior to or at the time of Customer's sale of 800 Directory
Assistance.

     7.5  The transfer of Allnet/Carrier/Customer 800 Numbers or Inbound
Services traffic to another carrier (other than 800 PIN Service traffic which is
not transferable) shall be subject to the Guidelines and the Allnet policies and
procedures for 800 number/traffic transfers in existence at the time of the
requested transfer.

     7.6  If an Allnet/Carrier/Customer 800 Number is temporarily blocked at
Customer's request made in accordance with Section 8.1, then for the period such
800 Number is being blocked Allnet shall, at Customer's written request and
expense, re-translate such 800 Number to Customer's customer service telephone
number.

     PIN 800 NUMBERS.
     ----------------

     7.7  Customer understands and agrees that due to the multiple End-User
nature of the 800 PIN Service, PIN 800 Numbers are controlled by Allnet and are
not transferable by Customer or End-Users to another carrier. End-Users to whom
PIN 800 Numbers are assigned forfeit the right to use such Numbers when their
services are cancelled. Customer shall in writing inform End-Users assigned a
PIN 800 Number of the conditions and limitations set forth above prior to or at
the time of Customer's sale of the 800 PIN Service.

     7.8  A.   When the 800 PIN Service is ordered by Customer, Allnet agrees to
initially provide Customer with three PIN 800 Numbers for use with the 800 PIN
Service. At such time as a PIN 800 Number has at least 1,000 PIN Numbers
assigned to it, and upon

                                       13
<PAGE>
 
the written request of Customer, Allnet agrees to provide an additional PIN 800
Number to Customer.

          B.   End-User calls to a PIN 800 Number for which a PIN Number is not
entered at the initial bong tone will be routed to an Allnet operator for manual
entry of the PIN Number. Up to 3% of total PIN 800 Number calls in any calendar
month may be routed to an Allnet operator for manual entry of the PIN Number
without charge to Customer. For all calls in excess of said 3%, Customer shall
be charged $0.25 per call.

          C.   If a End-User (i) enters the numerals "0000" as a PIN Number,
(ii) enters an invalid PIN Number (less than four digits or incorrect four
digits) on a second attempt to enter the PIN Number, or (iii) inquires of an
Allnet operator as to what a correct PIN Number is, then such calls will be
terminated to an Allnet 800 number to be delivered to Customer's customer
service center. Customer shall be charged for such calls at the then current
standard Allnet Solution(R) II 800 rates.

8.   SERVICE BLOCKAGE AND CANCELLATION.
     ----------------------------------

     8.1  Upon Customer's request sent via the applicable media hereunder,
Allnet shall use reasonable efforts to immediately block or cancel the service
to End-User ANIs or Codes, but in no event later than 24 hours after receipt of
said request. The same standard shall apply to blockage of an
Allnet/Carrier/Customer 800 Number associated with the Switched Services. Allnet
shall have no obligation to temporarily block Allnet/Carrier/Customer 800
Numbers associated with the Dedicated Services, but Allnet will at Customer's
request permanently cancel such 800 Numbers. Except in instances of its willful
misconduct, Allnet shall not be liable to Customer or End-Users for any damages,
costs or charges with respect to the failure of Allnet to block or cancel the
Services in accordance with Customer's request. Thus, Customer shall be solely
responsible for and shall defend, indemnify and hold Allnet harmless from and
against any claims and costs (including attorney fees) by End-Users or other
third parties related to the blocking of, or cancellation of the Services to, an
ANI, Code or 800 Number at the request of Customer.

     8.2  In the event an End-User violates any provision of the Tariff, Allnet
reserves the right without liability to immediately cancel the Services to such
End-User in accordance with the Tariff.

9.   CALL ABUSE MONITORING.
     ----------------------

     9.1  Allnet monitors its network in an attempt to detect unauthorized usage
("Call Abuse") of an ANI, Code or 800 Number ("Standard Monitoring"). Customer
authorizes Allnet to apply Standard Monitoring to End-User ANIs, Codes and 800
Numbers. If, pursuant to its Standard Monitoring, Allnet determines that Call
Abuse is or may be occurring, Allnet shall have the right, but not the
obligation, to block usage of the Services from any ANI, Code

                                       14
<PAGE>
 
or 800 Number associated with the suspected Call Abuse. If Allnet elects to
block the Services it shall use reasonable efforts to immediately notify
Customer of such blockage via facsimile, but in no event later than 24 hours
after the blockage. Allnet shall remove a blockage or replace a Code within 24
hours of Customer's written request. In lieu of blocking the Services, Allnet
may, in its sole option, contact Customer by facsimile and request Customer to
substantiate authorization for the suspected Call Abuse. Within 24 hours from
its receipt of the Allnet facsimile, Customer shall instruct Allnet by facsimile
as to what action, if any, it wishes Allnet to take regarding such suspected
Call Abuse. Customer agrees that if it fails to timely provide such instruction,
Allnet may take whatever action, including taking no action, it deems reasonable
under the circumstances.

     9.2  Except in instances of its willful misconduct, Allnet shall not be
liable to Customer or End-Users for damages, costs or charges, including charges
for Call Abuse, arising from acts or omissions of Allnet in applying or failing
to adhere to its Standard Monitoring practices or otherwise. Thus, Customer
shall be solely responsible for and shall defend, indemnify and hold Allnet
harmless from all expenses, charges and costs for usage attributable to End-User
ANIs, Codes and 800 Numbers, including all charges for Call Abuse.

     9.3  The Allnet facsimile number and contact person to be used for the
purposes set forth in this Section 9. shall be 313-433-4119, Attention: Bonnie
Levine. The Customer facsimile number and contact person to be used for said
purposes shall be _______________, Attention:____________________. Either party
may change its respective facsimile number or contact person upon prior written
notice to the other party.

10.  ADDITIONAL CUSTOMER REPRESENTATIONS/WARRANTIES & OBLIGATIONS.
     -------------------------------------------------------------

     10.1  Customer hereby represents and warrants that (i) it is certified to
do business in all jurisdictions in which it conducts business and it is in good
standing in all such jurisdictions, and (ii) it has been assigned a carrier
identification code by BellCore. Customer further represents and warrants that
it is certified by the proper regulatory agencies to provide interstate,
intrastate and international long distance services to End-Users in those
jurisdictions where such services are to be provided by Customer.

     10.2  Customer shall be responsible for obtaining signed letters of agency
("LOAs") from prospective End-Users in the format set forth in Exhibit 10.2
attached hereto and made a part hereof. Customer shall retain the signed LOAs
and promptly make the originals available upon the request of Allnet, a LEC or
any regulatory agency. Customer shall be responsible for LEC Primary
Interexchange Carrier change charges ("PIC Charges") that may be imposed on
Allnet as a result of End-Users moving onto or off of the Allnet network or as a
result of Customer's inability or refusal to provide original End-User LOAs when
requested. Any

                                       15
<PAGE>
 
such PIC Charges shall be billed to Customer periodically on a Customer Invoice.

     10.3  Customer shall be responsible for and pay all expenses in connection
with its business and its performance of this Agreement. Customer shall use its
best efforts to solicit and market the Services to prospective End-Users in
accordance with the terms of this Agreement and applicable law. Customer shall
at all times conduct its efforts in a commercially reasonable and ethical
manner. To the extent Customer makes any statements or representations to third
parties (including End-Users) with regard to Allnet, the Services, or the terms
of this Agreement, such statements or representations shall be true, accurate
and not misleading and shall conform to and be consistent with the terms herein.

     10.4  Customer shall not transfer an End-User to another long distance
carrier, except with an LOA signed by the End-User and dated after the date on
which the End-User was placed on the Allnet network, a copy of which LOA shall
be provided to Allnet. Notwithstanding the foregoing, in the event Allnet is in
default under the terms of this Agreement and fails to cure said default in
accordance with the terms hereof, then Customer may transfer the End-Users to
another long-distance carrier. Customer warrants that End-Users shall be
residential and/or commercial end-users of the Services and shall not be other
long distance carriers, resellers or aggregators.

     10.5  Customer may not use the Allnet name, logo, carrier identification
code or service marks without the prior written consent of Allnet. Customer
shall submit to Allnet for written approval copies of all marketing and
advertising materials involving the Allnet name, logo, carrier identification
code or service marks which Customer proposes to use in its marketing activities
prior to use of said materials. Allnet may in its sole discretion grant or
withhold its written consent or approval. Customer shall designate an individual
to serve as contact for all communications between itself and Allnet.

     10.6 A.   Customer shall be responsible for all customer service functions
for the End-Users and shall supply Allnet with a telephone number to which
Allnet can refer End-Users that call Allnet with customer service issues. A list
of the current Allnet network recordings that either identify Allnet as the
carrier or that reference the Allnet customer service telephone number are set
forth in Exhibit 10.6 A. attached hereto and made a part hereof. Customer
understands and agrees that Allnet may add, change or delete said recordings
from time to time and that Allnet is not obligated to change any recordings to
identify Customer as the carrier or to reference Customer's customer service
telephone number.

          B.   In performing its customer service functions, Customer shall
comply with the following quality assurance standards:

                                       16
<PAGE>
 
          (i)   All Customer telephone personnel shall be courteous and
responsive to End-Users at all times.

          (ii)  All End-User calls for customer service shall be answered
promptly.

          (iii) Customer shall answer all End-User correspondence by telephone
or in writing. If an End-User is not available by telephone after two attempts,
Customer shall respond in writing within five Business Days of receipt of End-
User correspondence.
             
          (iv)  Customer shall immediately notify Allnet of all End-User
inquiries or problems regarding technical issues associated with the Allnet
network. Customer shall refer such inquiries via procedures established by
Allnet and communicated to Customer. Customer shall provide Allnet with the End-
User's name, ANI, address and a description of the nature of the problem.

          (v)   Customer shall maintain an experienced and trained staff of
personnel in order to comply with its obligations under this Agreement,
including the foregoing quality assurance standards.

          (vi)  Customer shall comply with reasonable modifications to the
quality assurance standards that Allnet may from time to time request in
writing.

11.  PAYMENT TERMS AND OBLIGATIONS.
     ------------------------------

     11.1 Customer shall pay Allnet for the Services in accordance with the
following.

          A.   Allnet shall invoice Customer via facsimile on or about the fifth
Business Day after the close of each Billing Cycle for the Services to be
provided during the then current Billing Cycle and for any other sums due Allnet
hereunder (the "Customer Invoice"). Each Customer Invoice shall detail: (i) the
amount due Allnet, or the credit due Customer, [________________________________
________________________________________________________________________________
________________________________________________________________________________
_______________]. In the event the Letter of Credit (defined at 11.2 D.) is less
than [__________________________________________________________________________
________________________________________________________________________________
___________________________________], the Customer Invoice shall provide for a
pre-payment in an amount [______________________________________________________
_____________________________________________________]. Each Customer Invoice
will rate the Services at the then current Allnet tariffed rates, less any
applicable discount credits for which Customer may be eligible pursuant to
Exhibit 3.1.

          B.   Each Customer Invoice shall be paid by Customer via wire transfer
of immediately available U.S. funds to an account

                                       17
<PAGE>
 
designated by Allnet so that the payment is received by Allnet within twenty-one
days from the date of the Customer Invoice. Allnet agrees that (i) the Customer
Invoice date shall be the same day that the Customer Invoice is faxed to
Customer, and (ii) the Customer Invoice will be faxed on a Business Day. If
payment for a Customer Invoice is not received by Allnet by the second Business
Day prior to the due date of the Customer Invoice, Allnet agrees to notify
Customer's contact named in C. below via facsimile of such non-receipt.

          C.   The Customer facsimile number and contact person for purposes of
this Subsection 11.1 shall be ______________, Attention :______________________.
Customer may change said facsimile number and contact person upon written notice
to Allnet.

          D.   At the time Customer submits its initial Subscription Checklist
hereunder, it shall provide Allnet with an irrevocable, standby letter of credit
to secure Customer's payment obligations hereunder (the "LETTER OF CREDIT"). The
Letter of Credit shall be from a financial institution acceptable to Allnet

                                       18
<PAGE>
 
in the minimum amount of [________] and shall include the terms and conditions
set forth on Exhibit 11.2 D. attached hereto and made a part hereof. Allnet
shall not be obligated to provide the Services until such time as it receives
such a satisfactory Letter of Credit. Customer shall be responsible for all fees
and expenses in obtaining the Letter of Credit and any amendments, supplements
or replacements. Customer shall at all times during the term of this Agreement
maintain the Letter of Credit in full force and effect in accordance with the
terms herein. Customer shall have the option of furnishing a cash security
deposit in lieu of the Letter of Credit. In such event, the provisions herein
with respect to the Letter of Credit shall apply to such security deposit as
well. Provided that Allnet has been paid for all outstanding monies due it from
Customer hereunder, Allnet agrees that upon the termination or expiration of
this Agreement it shall promptly return to Customer any undrawn Letter of Credit
or any excess funds remaining from a draw on the Letter of Credit.

          E.   In the event Customer fails to timely pay a Customer Invoice in
full, Allnet shall have the right to draw on the Letter of Credit for the full
face amount. Allnet shall apply the funds from the Letter of Credit to any
outstanding Customer Invoice and credit any excess funds to Customer's account.
If the funds from the Letter of Credit are insufficient to fully pay any
outstanding Customer Invoice, then Allnet shall have the right to immediately
proceed with its remedies under Subsection 11.3.

     11.2 [Intentionally left blank.]

     11.3 A.   In the event Customer fails to timely pay any Customer Invoice
(other than a failure caused by the failure of Allnet to provide the notice set
forth in the last sentence of Subsection 11.1 B., in which event the due date
for the Customer Invoice shall be extended two Business Days) or fails to
maintain the Letter of Credit in full force and effect, Customer shall be in
breach of this Agreement which the parties hereby agree is an uncurable breach,
unless Allnet elects in writing to allow Customer to cure. If said uncurable
breach occurs, or if Customer otherwise breaches this Agreement (and the breach
remains uncured beyond any available cure period herein), Allnet shall have the
right at its sole option to do any or all of the following: (i) cease accepting
or processing orders for the Services; (ii) withhold delivery of any CDR Tapes
and cease Electronic Exchange; (iii) draw on the Letter of Credit and enforce
any guaranty granted herein; (v) terminate this Agreement without liability to
Allnet, including cancellation of the Services to Customer and/or End-Users;
(vi) collect from Customer for future Services that would have been provided but
for Customer's breach, including but not limited to the Monthly Surcharge and
other charges referenced herein; and (vii) pursue such other remedy or relief as
may be appropriate.

     11.4 Customer acknowledges and agrees that time is of the essence with
respect to the payment of the Customer Invoices and that it shall have no
opportunity to cure any failure by it to timely pay any Customer Invoice, absent
a written agreement by Allnet. Customer further acknowledges and agrees to the
following with respect to TERMINATION of this Agreement by Allnet for
Customer's non-payment:

          A.   That Customer shall not seek legal or equitable remedies,
including without limitation, injunctive relief, that would require Allnet to
continue providing the Services to End-Users through the Customer while any
monies due Allnet hereunder remain unpaid.

          B.   That upon termination of this Agreement, Allnet has the right to
cancel or block the Services, or to continue providing long distance services to
End-Users; that such cancellation or blockage may have an adverse impact on an
End-User's business; and that Customer shall be solely responsible for all
claims asserted by End-Users or other third parties associated with such
blocking or cancellation of the Services by Allnet.

                                       20
<PAGE>
 
          C.   That cancellation or blockage of the Services to End-Users will
have a negative impact on Customer's business for which Allnet shall have no
liability.

     11.5 Customer shall be responsible for payment of, or reimbursement to
Allnet of, Universal Service Fund and Lifeline Assistance Charges (presubscribed
line charges) as set forth in the National Exchange Carrier Association (NECA)
Tariff FCC #5, sections 8.5.1, 8.5.2 and 17.1.4 (A) & (B), as the same may be
amended from time to time, or any successor tariffs or sections. Said charges
shall be included on Customer Invoices and shall be calculated based on the
number of End-User ANIs presubscribed to Allnet. In addition, with respect to
the Services, Customer shall be responsible for payment of, or reimbursement to
Allnet for, (i) telecommunication relay service charges required by the
Americans with Disabilities Act or otherwise (both federal and state), (ii)
interexchange carrier fees payable to the FCC under the Omnibus Budget
Reconciliation Act of 1993 or otherwise, and (iii) universal service fund
charges, intraLATA compensation charges and similar fees and charges imposed on
Allnet by state regulatory agencies. The above charges shall be included on
Customer Invoices from time to time.

     11.6 Within ten Business Days after the Effective Date, Customer shall
furnish to Allnet, and keep current during the term of this Agreement, valid and
appropriate tax exemption certificates for all applicable jurisdictions
(federal, state and local) in which it performs the End-User billing. Customer
shall be responsible for properly taxing the End-Users and for the proper and
timely reporting and payment of applicable taxes to the taxing authorities and
shall defend, indemnify and hold Allnet harmless from payment and reporting of
all applicable federal, state and local taxes, including but not limited to,
gross receipts taxes, surcharges, franchise fees, occupational, excise and other
taxes (and penalties and interest thereon), relating to the Services. Such
indemnification shall include costs and expenses (including reasonable
attorney's fees) incurred by Allnet in settling, defending or appealing any
claims or actions brought against it relating to said taxes. In the event
Customer fails to provide and maintain the required certificates, Allnet shall
have the right, but not the obligation, to charge Customer for applicable taxes.

12.  TERM AND TERMINATION.
     ---------------------

     12.1 Subject to any early termination provisions provided herein, this
Agreement shall be for the term of two years from and after the Effective Date
(the "INITIAL TERM"). Unless a party provides the other party with at least
ninety days written notice prior to expiration of the Initial Term of its intent
to discontinue this Agreement upon expiration of the Initial Term, then upon
such expiration this Agreement shall automatically continue until the earlier to
occur of (i) termination as provided elsewhere herein, or (ii) termination by a
party at any time upon ninety days written notice.

                                       21
<PAGE>
 
     12.2 Upon written notice, this Agreement may be immediately terminated by
Allnet, without liability, (i) where provided for in this Agreement, (ii) in
accordance with its rights to cancel service as set forth in the Tariff, or
(iii) after the occurrence of any of the following events:

          A.   Upon Customer's insolvency, dissolution or cessation of business
operations.

          B.   The making by the Customer of any general assignment or
arrangement for the benefit of creditors; the filing by or against the Customer
of a petition to have it adjudged a bankrupt or for a reorganization or
arrangement under any federal or state bankruptcy or insolvency laws, unless any
such petition shall be dismissed or discharged within thirty days of its filing;
the appointment of a trustee or receiver to take possession of all or
substantially all the Customer's assets, where such fiduciary is not dismissed
within thirty days of its appointment; the attachment, execution, or other levy
or seizure of all or substantially all of the Customer's assets, where such
event is not discharged within thirty days of its initiation.

          C.   Pursuant to any order by the FCC denying Customer certification
or authorization to provide long distance services as contemplated herein.
Allnet shall have the right to cease providing the Services to Customer, but not
terminate this Agreement, in any state pursuant to an order by a Public Utility
or Service Commission denying Customer certification or authorization to provide
long distance services in such state.

          D.   The transfer of End-Users to another entity or long distance
carrier by Customer, unless transferred in accordance with Subsection 10.4 or
15.2 B.

     12.3  This Agreement may be terminated by Customer pursuant to paragraph 9.
of Exhibit 3.1.

     12.4  In the event of a breach of any term or condition of this Agreement
(except for payment of funds due Allnet which is covered by Section 11. or other
breaches the remedy for which is covered elsewhere herein) by a party, the other
party may terminate this Agreement upon thirty days written notice to the
breaching party, unless the breaching party cures the breach, or takes prompt
steps to cure a breach that cannot be reasonably cured during said period, prior
to expiration of said thirty day period. Customer's right to cancel service on
thirty days notice under the Tariff is superceded by its termination rights
under this Agreement.

     12.5  Subject to Subsection 13.6, upon termination or expiration of this
Agreement, each party shall immediately discontinue the use, if any, of all
trade names, service marks, trademarks, Proprietary Information and other
materials provided to it by the other party.

                                       22
<PAGE>
 
     12.6  In addition to its right to convert End-Users to Allnet customers as
provided elsewhere herein, upon termination or expiration of this Agreement,
Allnet shall have the right to continue providing long distance services to End-
Users on the Allnet network at the time of termination in accordance with the
rates and terms Allnet and an End-User may agree upon and to treat such
continuing End-Users as Allnet customers for all purposes.

13.  TRADE SECRETS AND CONFIDENTIALITY.
     ----------------------------------

     13.1 A.   Each party agrees that all information furnished to it and
identified by the other party as being confidential or proprietary information
or trade secrets (collectively referred to as "PROPRIETARY INFORMATION"), is,
and shall continuously remain, the sole and exclusive property of the party
furnishing the same (the party furnishing the Proprietary Information
hereinafter referred to as the "DISCLOSING PARTY" and the other party
hereinafter referred to as the "RECEIVING PARTY"). Each party shall treat the
Proprietary Information and the contents of this Agreement in a confidential
manner and, except to the extent necessary in connection with the performance of
its obligations under this Agreement, neither party shall directly or indirectly
disclose the same to any third party without the written consent of the
Disclosing Party.

          B.   The confidentiality obligations hereunder shall not apply to any
portion of the Proprietary Information which (i) is or becomes public knowledge
through no fault of the Receiving Party, (ii) is in the lawful possession of
Receiving Party prior to disclosure to it by the Disclosing Party (as confirmed
by the Receiving Party's records), (iii) is disclosed to the Receiving Party
without restriction on disclosure by a person who has the lawful right to
disclose the information, or (iv) is disclosed pursuant to the lawful
requirement or formal request of a governmental agency. In the event that the
Receiving Party is requested or legally compelled by a governmental agency to
disclose any of the Proprietary Information of the Disclosing Party, the
Receiving Party agrees on behalf of itself and its representatives that it will
provide the Disclosing Party with prompt written notice of such requests so that
the Disclosing Party has the opportunity to pursue its legal and equitable
remedies regarding such potential disclosure.

     13.2  The Proprietary Information is to be used by the Receiving Party only
for the purposes contemplated herein and the Receiving Party shall not disclose
the same to any one other than its employees who have a need to know and who
agree to be bound by the terms of this Section 13. The Proprietary Information
shall not be copied or retained by the Receiving Party in written form and all
originals and any copies or summaries thereof shall be returned to the
Disclosing Party upon request.

     13.3  Each party acknowledges that its breach or threatened breach of this
Section 13. may cause the Disclosing Party

                                       23
<PAGE>
 
irreparable harm which would not be adequately compensated by monetary damages.
Accordingly, in the event of any such breach or threatened breach, the Receiving
Party agrees that equitable relief, including temporary restraining orders or
preliminary or permanent injunctions, shall be an available remedy in addition
to any other legal remedies to which the Disclosing Party may be entitled.

     13.4  Neither party shall use the name, trade name, service marks, trade
marks, or printed materials of the other party, in any promotional or
advertising material, statement, document, press release or broadcast without
the written consent of the other party.

     13.5  The parties acknowledge the existence of a highly competitive long
distance marketplace and understand and agree that either party may offer to
provide long distance services to customers of the other party, including End-
Users, in accordance with such rates and terms as a party and the customer may
agree upon, provided however, that a party shall not at any time use Proprietary
Information of the other party in soliciting customers for long distance
services. Provided further, Customer shall not, in any marketing activities to
existing Allnet customers, use the fact that Allnet is the Customer's underlying

     --------------

     15.1  RELATIONSHIP OF PARTIES. Allnet and Customer acknowledge and agree
           -----------------------
that the relationship between them is solely that of independent contractors,
and nothing herein shall be construed to constitute the parties as
employer/employee, partners, joint ventures, franchisor/franchisee, co-owners,
or otherwise as participants in a joint or common undertaking. Neither party,
nor their respective employees, agents or representatives, shall have any right,
power or authority to act or create any obligation, express or implied, on
behalf of the other.

     15.2  LIMITATION ON ASSIGNMENT; SALE OF END-USER BASE.
           ------------------------------------------------

           A.  Neither party shall assign or transfer its rights or obligations
under this Agreement without the other party's prior written consent, which
consent shall not be unreasonably withheld. Notwithstanding the foregoing,
Allnet may assign this Agreement to its parent, successor in interest or a
subsidiary without Customer's consent, and Customer may assign this Agreement to
its parent, successor in interest or a wholly owned subsidiary upon prior
written notice to Allnet and without Allnet's consent, provided Customer is not
in default hereunder and its assignee agrees in writing to assume Customer's
obligations hereunder. Any assignment or transfer without the required consent
shall be void.

          B.   Except as otherwise provided under Subsection 10.4, Customer
shall not assign, sell, convey or otherwise transfer all or a portion of its
End-User customer base (collectively "TRANSFER") without the prior, written
consent of Allnet, which consent shall not be unreasonably withheld provided
Customer complies with the conditions referenced below. Customer shall provide
Allnet with at least sixty days prior, written notice of Customer's intent to
initiate a Transfer. Within thirty days from the date of receipt by Allnet of
Customer's said notice of intent, Allnet shall in writing inform Customer of the
reasonable conditions required by Allnet for its consent to the Transfer, which
conditions will at a minimum include compensation to Allnet to cover charges for
future Services that would have been provided but for the Transfer, including
but not limited to, the Minimum Charge, costs for the Custom Program and other
charges referenced

                                       25
<PAGE>
 
in this Agreement. If Allnet fails to timely provide said conditions, Allnet
shall be deemed to have consented to the Transfer. The parties agree that (i)
Customer's breach of this Subsection 15.2 B. is an uncurable breach, unless
Allnet elects in writing to allow Customer to cure, and (ii) upon the occurrence
of such breach Allnet may immediately proceed with its remedies under Subsection
11.3.

     15.3  ENTIRE AGREEMENT. This Agreement, the Tariff and any Exhibits
           ----------------

concerning the subject matter hereof, and any representations or agreements,
oral or otherwise, not embodied herein, are superceded by the terms hereof and
shall be of no force or effect.  Except as otherwise set forth herein, Allnet
makes no representations concerning the Services or otherwise. This Agreement is
intended to supplement the Tariff, but in the event of a conflict between the
provisions of this Agreement and the Tariff, the provisions of this Agreement
shall control to the extent of such conflict. Without limiting the foregoing,
Paragraphs 4.F. and 9. of Exhibit 2.1 are expressly superceded by the terms of
this Agreement. Subject to Allnet's limitation of liabilities under Subsection
14.1, Paragraph 4.G. of said Exhibit shall be reciprocal to the extent that
either party institutes legal action under this Agreement and prevails in such
action.

           ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. The individuals signing

authorized to bind and do so bind the party on behalf of which they are

required by the FCC, a state Public Utility or Service Commission, or any other
governmental body or agency having jurisdiction over their respective
businesses. Upon request, each party shall supply the other with copies of such
tariffs, permits, certifications , etc .

     15.6  THIRD PARTIES.  The provisions of this Agreement and the rights and
           -------------
obligations created hereunder are intended for the sole benefit of Allnet and
Customer, and shall not create any right, claim or benefit on the part of any
person not a party to this Agreement, including End-Users.

     15.7  SURVIVAL OF PROVISIONS. Any obligations of the parties relating to
           ----------------------
monies owed, as well as those provisions relating to 

                                       26

confidentiality, security interests, limitations on liability and actions and
indemnification, shall survive termination or expiration of this Agreement.

underlying transport provider, and to act as my agent in all matters related to 
providing my long distance service for the telephone number(s) listed on this

company for subscribing my long distance service to Carrier, (iv) there may be a
charge from my local telephone company should I decide to change my long 
distance carrier after my service begins, and (v) I may be serviced and billed 
directly by Allnet at such time as Allnet ceases being the transport provider 
for the Carrier with respect to my long distance service.

This Letter of Agency shall remain in effect until Customer signs a new Letter

      herein, all material necessary or appropriate public or private consents,
      permissions, agreements, licenses, or authorizations to which it may be
      subject have been obtained.

      4.  TERM:  WilTel's obligation to provide Service under this Agreement
shall be effective over the period commencing with the Effective Date of this
Agreement and continuing through and including August 31, 1998 (the "Term").
With respect to any Service Order for which the applicable Service Commitment
Period has not been satisfied by the end of the Term, the terms and conditions
of this Agreement will remain in full force and effect until such Service
Commitment Period has been satisfied.  Upon the expiration of the Term, all
charges relevant to the Service will remain in effect and Service which has met
its minimum Service Commitment Period as described herein will be subject to
termination by either party upon not less than thirty (30) days prior written
notice to the other party.

      5.  SERVICE ORDERS: Service requested by Customer hereunder shall be
requested on (i) WilTel Digital Service Description forms in effect from time to
time or Customer's forms accepted in writing by an Authorized Headquarters
Representative of WilTel as hereinafter provided, or (ii) through the WilTel
Electronic Order Processing system whereby Customer receives written
confirmation from WilTel of the Service it has requested (hereinafter
collectively referred to as "Service Orders"). Each Service Order shall
reference this Agreement by Digital Service Agreement number ("DSA#") and shall
become a part of this Agreement only to the extent that it specifies the type of
Interexchange Service, quantity of circuits, originating and terminating cities,
Requested Service Date, Service Commitment Period, charges and other information
necessary for WilTel to provide the Service to Customer. Any other terms and
conditions that are typed, printed or otherwise included in any Service Order
shall be deemed to be solely for the convenience of the parties. No action by
WilTel (including, without limitation, provision of Service to Customer pursuant
to such Service Order) shall be construed as binding or estopping WilTel with
respect to such term or condition, unless the Service Order containing said
specific term or condition has been signed by an Authorized Headquarters
Representative of WilTel.

     6.  SERVICE COMMITMENT PERIOD, START OF SERVICE AND AUTOMATIC
EXTENSION: The Service Commitment Period for the Interexchange and Ancillary
Services subject to recurring charges and described in a Service Order shall
commence on

                                                                    ------------

the Requested Service Date or the date upon which the Service first becomes
available in conformity with the Technical Standards, whichever is later ("Start
of Service").

     7.   SERVICE TO BE PROVIDED:

     (A)  WilTel agrees to offer and provide Customer with DS-0 level
     Interexchange Service, DS-l level Interexchange Service, Multiple DS-l
     level Interexchange Service and DS-3 level Interexchange Service that is
     available and uncommitted (i.e., Service for which WilTel does not have
     firm orders) between and among (i) any two (2) cities comprised exclusively
     of the WilTel On-Net Cities ("On-Net Service"), and (ii) one or more WilTel
     Extended Cities ("Extended Service") both of which are set forth in
     Attachment "1" (or such other cities as may be mutually agreed upon from
     time to time and documented via a Service Order executed by a duly
     authorized representative of each party). On-Net Service and Extended
     Service are collectively referred to as "Interexchange Service".

     (B)  The rates set forth in Section 10 below shall apply to (x) On-Net
     Service with respect to DS-1, Multiple DS-1 and DS-3 level Interexchange
     Service, and (y) Extended Service only with respect to DS-l level
     Interexchange Service; provided, all other Extended Service shall be
     subject to rates as determined by WilTel on an individual case basis and
     agreed upon, in writing, by the parties hereto.

     (C)  In addition, it is further acknowledged by Customer that WilTel can
     not make an advance guarantee of the delivery interval for Service
     originating or terminating in WilTel Extended Cities set forth in
     Attachment "1". Further, WilTel shall not be obligated to accept a Service
     Order conforming with the provisions of this Section 7 for On-Net Service
     pursuant to which Customer requires a Requested Service Date for such
     Service described therein which is greater than ninety (90) business days,
     and less than WilTel's standard installation intervals which are (i) twelve
     (12) business days with respect to DS-l level Interexchange Service, or
     (ii) ten (10) business days with respect to DS-3 level Interexchange
     Service from the date Customer submits such Service Order to WilTel (the
     "Standard Interval"). Provided, WilTel's Standard Intervals only apply
     when such On-Net Service is available and uncommitted as provided in
     Subsection (A) above.

                                                                    ------------

     (D)  WilTel will also provide (i) Customer with Ancillary Services (as
     hereinafter defined), and (ii) agency service for Customer in provisioning
     Customer's Local Access (as hereinafter defined) all as may be requested by
     Customer and accepted by WilTel in accordance with the terms hereof
     (Interexchange Service, Ancillary Service and agency for Customer's Local
     Access shall be collectively referred to herein as the "Service").
     WilTel's Installation and Ancillary Charges as of the Effective Date are
     shown on Exhibit "1", a copy of which is attached hereto and incorporated
     herein by reference. WilTel's liability for delays in installation, testing
     and operation of Interexchange Service, Local Access and Ancillary Services
     is limited in Section 21 of this Agreement.

     8.   LOCAL ACCESS AND ANCILLARY SERVICES:

     (A)  WilTel may, when reasonable under the circumstances, upon Customer's
     or an individual Member's request, act as Agent for Customer or such
     individual Member with responsibility for provisioning and the initial
     testing of an interconnection (reasonably coordinated with Start of
     Service) between selected Interexchange Service and a Customer or
     individual Member designated termination point and/or service (e.g.,
     Feature Group Service) ("Local Access"). Charges to Customer or the
     individual Member for Local Access Service ministered on behalf of Customer
     or such individual Member by WilTel shall not exceed charges Customer or
     such individual Member would otherwise pay the same local access provider
     for the relevant interconnection and/or service.

     (B)  WilTel will also provide Customer and the individual Members other
     services (which are available and provided by WilTel), including but not
     limited to: (i) multiplexing/demultiplexing service ("Muxing"), (ii)
     digital cross-connect service ("DCS"), or (iii) extraordinary service for
     reasons including but not limited to: (a) Customer's request to expedite
     Service availability to a date earlier than WilTel's published installation
     interval or a previously accepted Requested Service Date; (b) Service
     redesign or other activity occasioned by receipt of inaccurate information
     from Customer; (c) reinstallation charges following any suspension of the
     Service for cause by WilTel; (d) Customer's request for use of routes or
     facilities other than those selected by WilTel for provision of the
     Service; and (e) other circumstances in which extraordinary costs and
     expenses are generated by Customer and reasonably

                          Page 6 of 27                              CONFIDENTIAL
                                                                    ------------

     incurred by WilTel (services under this Subsection (B) are collectively
     referred to herein as "Ancillary Services"). Recurring and non-recurring
     charges to Customer for Local Access (including WilTel's Local Access
     Coordination Fee) and Ancillary Services shall be established as of
     WilTel's acceptance of the Service Order relevant thereto. A list of
     WilTel's Installation and Ancillary Service charges are shown on Exhibit
     "1" which is attached hereto and incorporated herein by reference.
     RECURRING CHARGES FOR LOCAL ACCESS BILLING ADMINISTERED BY WILTEL AND
     CHARGED TO CUSTOMER SHALL BE SUBJECT TO ADJUSTMENT AT SUCH TIMES AS WILTEL
     SHALL DETERMINE, NOT TO EXCEED THE PREVAILING CHARGES OF SUCH LOCAL ACCESS
     PROVIDERS AS WOULD OTHERWISE BE PAID DIRECTLY BY CUSTOMER FOR THE RELEVANT
     INTERCONNECTION OR SERVICE.

     (C)  Commencing with the Effective Date of this Agreement, WilTel agrees to
     charge Customer [__________________] of WilTel's standard rates for the DS-
     l level entrance facilities or local serving arrangements WilTel has with
     the relevant local telephone operating compan(ies) (the "LSA Rates"). The
     LSA Rates as described herein will remain in full force and effect until
     such time as WilTel modifies its rates (either by an increase or a
     decrease) relative to entrance facilities or local serving arrangements
     generally available to its other carrier customers. In the event Customer
     is billed directly by the Local Access provider(s) for entrance facilities
     or local serving arrangements, the parties agree to cooperate in preventing
     WilTel's duplication of charges to Customer for the same entrance
     facilities. In the event Customer has been charged by the Local Access
     provider(s) for such charges, upon WilTel's receipt of reasonable
     documentation substantiating such charges and Customer's payment therefor,
     WilTel agrees to either issue Customer a credit for such charges or
     reasonably assist Customer in obtaining a refund from the appropriate Local
     Access provider.

     9.   CUSTOMER'S COMMITMENT/DEFICIENCY CHARGE:

     (A)  Commencing with the March, 1996 billing period and continuing through
     the end of the Term (the "Commitment Period"), Customer agrees to maintain,
     on a take-or-pay basis, Monthly Recurring Interexchange Service Charges of
     a least [______] ("Customer's Commitment"). It is further understood by the
     parties that certain Members have individually committed for a certain
     portion of Customer's Commitment as further described in

                                 Page 7 of 27                       CONFIDENTIAL
                                                                    ------------

     Section 17 below. Provided, however, except as provided in Section 17,
     nothing contained herein shall be construed as to make ACCA or any Member
     directly liable to WilTel for the monthly recurring Interexchange Service
     Charges of any other Member.

     (B)  Subject to Section 17 below if, in any month during the Commitment
     Period, a Member's actual Monthly Recurring Interexchange Service Charges
     do not equal at least such Member's portion, if any, of Customer's
     Commitment as shown in the Commitment Schedule described in Subsection
     17(B), then for such month(s), such Member agrees to pay WilTel the
     difference between such Member's actual Monthly Recurring Interexchange
     Service Charges and such Member's portion, if any, of Customer's Commitment
     (the "MONTHLY DEFICIENCY CHARGE"). Monthly Deficiency Charges, if any,
     determined in accordance with this Subsection (B) shall be due at the same
     time Service charges are due hereunder.

     (C)  The parties hereby specifically agree that the provisions contained
     herein describing a deficiency charge represents a mutual good faith
     estimate of, and bears a reasonable relationship to, the actual damages to
     WilTel in the event of such deficiency and do not represent a penalty of
     any kind, and that such deficiency charge is an obligation of ACCA and the
     Members subject to specific performance.

     (D)  For purposes of this Agreement, "MONTHLY RECURRING INTEREXCHANGE
     SERVICE CHARGES" will not include pro-rated charges for Interexchange
     Service, Local Access charges, Ancillary Service charges, additional
     Charges (as defined below), other recurring or non-recurring charges for
     space, facilities or any other charges other than those charges identified
     by the relevant WilTel invoice as monthly recurring interexchange service
     charges for private line service.

     (E)  In the event Customer submits a firm Serviced Order for DS-l or DS-3
     level On-Net Service (other than orders submitted under Sections 11 or 12
     below) and WilTel can not deliver Service within [_________] business days
     or some other longer interval agreed to by Customer, and Customer orders
     and is provided such Service by another carrier, then solely for purposes
     of determining if Customer has met Customer's Commitment described in
     Subsection (A) above, WilTel agrees to include an amount equal to WilTel's
     Monthly Recurring Interexchange Service Charges for such Service times the

                          Page 8 of 27                              CONFIDENTIAL
                                                                    ------------

     number of months such Service is actually installed by the other carrier.
     Upon request by WilTel, Customer agrees to provide adequate documentation
     reasonably acceptable to WilTel to substantiate Customer's ordering and
     being provided Service under this Subsection from another carrier.

      10. MONTHLY RECURRING INTEREXCHANGE SERVICE RATES: Customer will receive
the following rates and discounts for Service ordered hereunder.  Customer will
not receive any other discounts unless specifically set forth herein.

     (A)  The Base Rate per VGE per V&H Mile for On-Net DS-3 level

     (B)  The Base Rate per VGE per V&H Mile for On-Net and Extended DS-l level
     Interexchange Service will be as follows based on Customer's Spending Level

     (C)  Notwithstanding anything to the contrary contained herein, commencing
     with the Effective Date and continuing through and including February 28,
     1996, Customer's Monthly Spending Level will be deemed to be the greater of
     (i) [______], or (ii) Customer's actual Monthly Spending Level. Commencing
     March 1, 1996 and continuing through the end of the Term, Customer's rates
     for DS-l and DS-3 level Interexchange Service as described above will be
     the rate which corresponds with Customer's actual Monthly Spending Level as
     determined under Subsection (F) below.

     (D)  The Base Rate for Multiple DS-l level Interexchange Service ("Multiple
     DS-1 Service") will be the DS-l level Interexchange Service rates described
     in Subsection (B) above. Multiple DS-l level Interexchange Service between
     and among WilTel On-Net Cities and Extended Cities ordered solely by one
     Member (i.e., Members may not allocate Service under this Subsection (D))
     will be subject to the discounts described below provided all of the
     following conditions are met:

          (i)   Customer orders at least six (6) DS-l circuits between or among
          On-Net Cities or Extended Cities at one time (the "Circuit Package");

          (ii)  the Requested Service Date(s) relevant to the DS-s are subject
          to WilTel's standard intervals and, if more than one date is
          requested, the dates are within the same thirty (30) period; and

          (iii) the Service Commitment Period for each of the DS-ls in question
          is twelve (12) months.

     In the case of an initial Circuit Package comprised exclusively of existing
     DS-s, the Multiple DS-1 level Interexchange Service discount and twelve
     (12) month Service Commitment Period will commence as of the second monthly
     billing period following the month in which the Service Order therefor is
     submitted. If Customer desires to create a larger Circuit Package or create
     an initial Circuit Package from existing DS-ls and incremental new DS-ls
     (e.g., take a Circuit Package of 6 to a Circuit Package of 10 DS-ls; or,
     create an initial Circuit Package of at least 6 DS-ls from an existing 4 
     DS-ls plus an additional incremental 2 DS-ls), Customer will first identify
     all DS-ls to be in the resulting Circuit Package. All circuits within the
     resulting Circuit Package will be subject to a twelve (12) month Service
     Commitment Period commencing as of the date the last circuit comprising the
     package is installed. If through the creation of a larger Circuit Package
     existing DS-ls should be subject to a greater level of discount, the
     applicable discount shall commence for the existing DS-ls as of the date
     the last circuit in the larger Circuit Package is installed, and the
     applicable discount for each new incremental DS-l relevant to the larger
     Circuit Package shall commence as of Start of Service for each such
     incremental DS-l.

      Interexchange Service between will be [___].

     (F)  For purposes of this Section 10, "Monthly Spending Level" will include
     (i) "Monthly Recurring Interexchange Service Charges" (as defined in
     Subsection 9(D) above), and (ii) provided Customer's Monthly Recurring
     Interexchange Service Charges are at least [______], [_____________] of
     Customer's International monthly measured and per call usage charges for
     Switched Services purchased by Customer from WilTel (excluding Local Access
     charges, Ancillary Service charges, special feature charges such as,
     Authorization codes or CDR Tapes, or any other charges other than those
     identified by the relevant WilTel invoice as Switched Service charges).
     With respect to Service ordered after February 28, 1996 and each month
     thereafter through the end of the Term, the Monthly Spending Level will be
     determined at the end of each month and will be based on WilTel's latest
     private line invoice to Customer. The Monthly Spending Level determined at
     the time of such computation shall be effective from the first through the
     last day of each calendar month following the month in which the
     computation is me.

      11.  DS-1 LEVEL SERVICE UPGRADES:  Provided Customer is not in default
under the terms of this Agreement, Customer shall have the right to replace up
to twenty-eight (28) DS-1 circuits between two (2) WilTel Cities (each of which
DS-1 circuits has been in place for a minimum of ninety (90) days) with DS-3
level Interexchange Service between the same two cities ("Upgraded DS-3
Service") upon at least forty-five (45) days' prior written notice to WilTel.
The DS-l level Interexchange Service in question shall be canceled as of a date
not earlier than the date Service commences for the Upgraded DS-3 Service (i.e.,
44.736 Mbps level).  The charge for Upgraded DS-3 Service under this Section 11
shall be at the rates set forth in Section 10 above and the Upgraded DS-3
Service shall be subject to the Minimum Service Commitment Period described in
Section 14 below commencing as of the date Service commences for the Upgraded
DS-3 Service.  Upgraded DS-3 Service under this Section 11 is subject to the
additional capacity being available and uncommitted (if additional capacity is

required) and WilTel is under no obligation to construct additional circuits for
Customer.  Further, the replacement of DS-1 circuits with Upgraded DS-3 Service
in accordance with this Section 11 shall not result in Customer being subject to
a cancellation charge for the DS-ls in question pursuant to Section 19 below.

      12.   SUBSTITUTE ON-NET DS-1 LEVEL SERVICE:  Provided Customer is not in
default of this Agreement, Customer may substitute DS-1 level Interexchange
Service between and among WilTel Cities (the "Substitute DS-1 Service") for DS-1
level Interexchange Service between WilTel Cities then being provided to
Customer hereunder ("Replacement DS-1 Service") without incurring a cancellation
charge pursuant to Section 19 below provided the following conditions are met:

      (i)   As of the effective date of cancellation, the Replaced DS-1 level
      Interexchange Service has been maintained for a minimum of ninety (90)
      days from the Start of Service therefor.

      (ii)  Customer provides notice of such cancellation and concurrently
      therewith submits a Service Order for the Substitute DS-1 level
      Interexchange Service for installation by WilTel within WilTel's standard
      installation intervals.

      (iii) The Substitute DS-1 level Interexchange has a Requested Service Date
     not later than the effective date of cancellation for the Replaced DS-1
     Service.

      (iv)  The Substitute DS-1 Service has a monthly recurring Interexchange
     Service charge equal to or greater than the monthly recurring Interexchange
     Service charge of the Replaced DS-1 Service.

Further, the Substitute DS-1 Service will be subject to the minimum Service
Commitment Period set forth in Section 14 below commencing with the Start of
Service date for the Substitute DS-1 Service.

      13.   DIVERSELY ROUTED SERVICE:  WilTel will provide DS-1 or DS-3 level
Interexchange Service (i.e., not Multiple DS-1 Service) to the extent diverse
routing is available under facilities owned by WilTel between and among WilTel
On-Net Cities designated by Customer as Service used for diversity ("Diversely
Routed Circuits"). The rates for such Diversely Routed Circuits will be as set
forth in Section 10 above provided the route miles relative to each Diversely

                          Page 12 of 27                             CONFIDENTIAL
                                                                    ------------
<PAGE>
 
Routed Circuit must be less than or equal to [__] of the primary route selected
by WilTel in connection with the same city pair.  If the route miles relative to
each Diversely Routed Circuit are greater than [__] of the primary route,
WilTel, at its sole discretion, may provide the Diversely Routed Circuits on an
individual case basis.

      14. MINIMUM SERVICE COMMITMENT PERIOD/MINIMUM CHARGE:

     (A)  Subject to Subsection (B) below, the minimum Service Commitment period
     for Interexchange Service provided hereunder will be as follows
     (collectively referred to as the "Minimum Service Commitment Period"):

          (i)   DS-0 level Interexchange Service between WilTel Cities or one or
                more WilTel Extended Cities - [______________].

          (ii)  DS-1 level Interexchange Service between WilTel Cities - [______
                _____].

          (iii) DS-1 level Interexchange Service between one or more WilTel
                Extended Cities - [__________________].

          (iv)  DS-3 level Interexchange Service between WilTel Cities - [_____
                __________].

     (B)  The Service Commitment Period for Existing Service which is in effect
     as of the Effective Date shall continue in full force and effect (the
     "Existing Commitment Period").  Upon expiration of any Existing Commitment
     Period or the Minimum Service Commitment Period as determined under
     Subsection (A) above, the rates for such Service as determined under
     Section 10 above will continue in full force and effect through the end of
     the Term at which time such Service may be terminated by either party upon
     thirty (30) days' prior written notice to the other party.  Provided,
     however, at any time during the Term, Customer may elect to "renew" Service
     (including Existing Service) at the rates then in effect (i.e., based on
     Customer's then existing Monthly Spending Level as described in Subsection
     10 (F) above) by notifying WilTel at least thirty (30) days in advance of
     the effective date of the renewal (the "Renewal Effective Date") for such
     Service (hereinafter referred to as "Renewed Service").

                          Page 13 of 27                             CONFIDENTIAL
                                                                    ------------
<PAGE>
 
     In such case, Renewed Service will be subject to a new Minimum Service
     Commitment Period in accordance with Subsection (A) above which will
     commence on the first day following the Renewal Effective Date.

     (C)  The minimum monthly recurring Interexchange Service charge for (i)
     each DS-0 circuit comprising DS-0 level Interexchange Service shall be [_],
     (ii) each DS-1 circuit comprising DS-1 level Interexchange Service
     (including Multiple DS-1 Interexchange Service) shall be [__], and (iii)
     each DS-3 circuit comprising DS-3 level Interexchange Service shall be
     [____].

     15.  CUSTOMER RESPONSIBILITIES:  Customer has sole responsibility for
installation, testing and operation of facilities, services and equipment other
than that specifically provided by WilTel as part of the Service described in a
Service Order ("Customer Facilities"). In no event will the untimely
installation or non-operation of Customer Facilities (including Local Access
when Customer is responsible therefor and customer premise equipment) relieve
Customer of its obligation to pay charges for the Service as of Start of
Service.

     16.  ADDITIONAL CHARGES: Customer acknowledges and understands that all
charges stated in Service Order are computed by WilTel exclusive of any
applicable federal, state or local use, excise, gross receipts, sales and
privilege taxes, duties, fees or similar liabilities (other than general income
or property taxes), whether charged to or against WilTel or Customer for the
Service provided to Customer ("Additional Charges"), and that such additional
Charges shall be paid by Customer in addition to all other charges provided for
herein.

     17.  PAYMENT OF CHARGES:

     (A)  Payment for (i) all pro-rated monthly recurring charges (charges for
     monthly Service provided for less than a calendar month), installation and
     other non-recurring charges shall be due on the first day of the month
     following the month in which the Service was provided, and (ii) all monthly
     recurring charges for full months during which the Service is to be
     provided following Start of Service shall be due in advance on the first
     day of that month (collectively, the "Due Date"). WilTel's invoice to
     Customer will be computed each calendar month in advance of the Due Date
     for charges as provided above and as of a billing cut-off date

                          Page 14 of 27                             CONFIDENTIAL
                                                                    ------------
<PAGE>
 
     determined by WilTel, which shall not be earlier than the fifth (5th) day
     or later than the fifteenth (15th) day of the month in which such
     computation is me ("WilTel Billing Cut-Off Date"). The invoice date shall
     not be determinative of the billing cut-off date used by WilTel in the
     preparation of any particular invoice.

     (B)  A schedule showing the individual Member's allocable share of
     Customer's Commitment described in Subsection 9(A) above is attached hereto
     and incorporated herein by reference (the "Commitment Schedule"). WilTel
     agrees to provide (i) a separate monthly invoice to ACCA and each Member
     detailing each Member's respective private line interexchange service
     charges under this Agreement for which such Member is responsible as
     described on the Commitment Schedule, (ii) an invoice to the ACCA
     Administrator showing the total amount of all Members' private line
     interexchange service charges and the resulting total Monthly Deficiency
     Charge, if any, and (iii) any Suspension Notices sent to Delinquent
     Customers as described in Section 18 below.

     (C)  In order to ensure performance of this arrangement as set forth
     herein, each Member agrees to provide WilTel with a satisfactory
     irrevocable standby letter of credit (in a form reasonably acceptable to
     WilTel) in an amount equal to its respective portion of Customer's
     Commitment as shown on the Commitment Schedule (individually referred to a
     "Member's LOC" and collectively as the "Members' LOCs"). Within ninety (90)
     days after the Effective Date, WilTel agrees to review in good faith each
     Member's credit, including without limitation, such Member's payment
     history, and if reasonable, terminate such Member(s)' LOC requirements
     described herein. Provided, subject to adjustment as provided herein, the
     total amount of all Members' LOCs delivered to WilTel hereunder shall not
     be less than Customer's Commitment described in Subsection 9(A) above.
     During the Term of this Agreement, WilTel and the ACCA Administrator agree
     to meet to review the amount of Members' LOCs in relation to the estimated
     Monthly Recurring Service Charges of all Members (i) every quarter, or (ii)
     in the event a Member's estimated Monthly Recurring Interexchange Service
     Charges exceed the amount shown on the Commitment Schedule attributable to
     such Member by more than twenty-five percent (25%). If WilTel and the ACCA
     Administrator determine that a particular Member should increase its
     respective LOC, such Member will supply WilTel with an

                          Page 15 of 27                             CONFIDENTIAL
                                                                    ------------
<PAGE>
 
     additional LOC or a new LOC which takes into account the increased amount
     required by WilTel within five (5) business days.

     (D)  Each Member agrees to remit payment to WilTel at the remittance
     address indicated on WilTel invoices to such Member. In the event a Member
     fails to pay WilTel's invoice in full or remit payment to the proper
     address on or before thirty (30) days after the Due Date, such Member shall
     also pay a late fee in the amount of the lesser of one and one-half percent
     (l 1/2 %) of the unpaid balance per month or the maximum lawful rate under
     applicable state law. Notwithstanding the foregoing, late fees shall apply
     to, but shall not be due and payable for, amounts reasonably disputed by a
     Member for a period of ninety (90) days following the Due Date therefor
     (the "Alternate Due Date"), provided: (i) such Member notifies WilTel of
     the basis for such dispute in writing on or before thirty (30) days after
     the Due Date; and (ii) negotiates in good faith with WilTel for the purpose
     of resolving such dispute within said ninety (90) day period. In the event,
     such dispute is resolved in favor of WilTel, such Member will pay to WilTel
     the once disputed amounts together with the applicable late fees within ten
     (10) business days of the resolution. In the event such dispute is resolved
     in favor of such Member, such Member will receive a credit for the amounts
     determined not to be owed together with a credit for the applicable late
     fees. In the event the dispute cannot be resolved within such ninety (90)
     day period, all disputed amounts together with late fees shall become due
     and payable on the Alternate Due Date, and this provision shall not be
     construed as preventing such Member from pursuing any available legal
     remedies.

     (E) WilTel agrees to collect those amounts due WilTel attributable to each
     Member from the Member who incurred such charges. In the event a Member
     fails to pay WilTel its respective undisputed charges in full by the Due
     Date for such charges ("Delinquent Member"), WilTel (without further notice
     to or approval by such Delinquent Member) may satisfy any outstanding
     amount (the "Past Due Amount") from such Delinquent Member's respective
     LOC. In the event such Delinquent Member's LOC does not satisfy WilTel's
     invoice in full such Delinquent Member shall remain liable for such Past
     Due Amount.

                                                                    ------------

     18.  SUSPENSION OF SERVICE:

     (A)  In the event payment in full is not received from a Delinquent Member
     on or before thirty (30) days following the Due Date with respect to
     undisputed amounts or on or before ninety (90) days following the Due Date
     with respect to amounts reasonably disputed in accordance with the
     prescriptions of Section 17 above, WilTel shall have the right (in addition
     to any rights it has under Section 17 above) after giving such Delinquent
     Member ten (10) days notice and opportunity to cure (the "Suspension
     Notice") to suspend all or any portion of the Service to such Delinquent
     Member, or upon subsequent notice, all or any additional portions of the
     Service to such Delinquent Member; and, in either event, until such time as
     the Delinquent Member has paid in full all charges then due, including any
     late fees as specified herein. Following such payment, WilTel shall be
     required to reinstitute Service to such Delinquent Member only upon the
                                                               ----  
     provision by the Delinquent Member to WilTel of satisfactory assurance
     (such as a deposit) of such Delinquent Member's ability to pay for Service
     and such Delinquent Member's advance payment of the cost of reinstituting
     Service. If the Delinquent Member fails to make such payment by a date
     determined by and acceptable to WilTel, such Delinquent Member will be
     deemed to have canceled the Service suspended effective as of the date of
     such suspension. In such case, the other Members will be required to
     allocate the Delinquent Member's portion of Customer's Commitment among the
     other Members.
     
     (B)  Further, if at any time there is a material adverse change in a
     Member's creditworthiness, then in addition to any other remedies available
     to WilTel, WilTel may elect, in its sole discretion, to exercise one or
     more of the following remedies: (i) cause Start of Service for Service
     described in a previously executed Service Order submitted by such Member
     to be withheld; (ii) cease providing Service to such Member pursuant to a
     Suspension Notice; (iii) decline to accept a Service Order or other
     requests from such Member to provide Service which WilTel may otherwise be
     obligated to accept; and/or (iv) condition its provision of Service or
     acceptance of a Service Order on such Member's assurance of payment which
     shall be a deposit or such other means to establish reasonable assurance of
     payment. An adverse material change in a Member's creditworthiness shall
     have occurred upon one or more of the following events: (a) such Member's
     default of its obligations to WilTel under this

                          Page 17 of 27                             CONFIDENTIAL
                                                                    ------------
<PAGE>
 
     or any other agreement with WilTel; (b) failure of such Member to make full
     payment of charges due hereunder on or before the Due Date on three (3) or
     more occasions during any period of twelve (12) or fewer months or such
     Member's failure to make such payment on or before the Due Date in any two
     (2) consecutive months; (c) acquisition of such Member (whether in whole or
     by majority or controlling interest) by an entity which is insolvent, which
     is subject to bankruptcy or insolvency proceedings, which owes past due
     amounts to WilTel (or any entity affiliated with WilTel) or which is a
     materially greater credit risk than such Member; or, (d) Customer's being
     subject to or having filed for bankruptcy or insolvency proceedings or the
     legal insolvency of such Member.

     19.  CANCELLATION:

     (A)  After a Service Order is accepted by WilTel, Customer may cancel all
     or a portion of the Service described therein if Customer provides written
     notification thereof to WilTel thirty (30) days in advance of the effective
     date of cancellation. In such case, Customer shall pay to WilTel all
     charges for Service provided through the effective date of such
     cancellation plus a cancellation charge determined as follows: (i) if the
     Service Commitment Period for the canceled Interexchange Service is one (1)
     year or less, then the cancellation charge shall be an amount equal to the
     balance of the monthly Interexchange Service charges (then in effect at the
     time of cancellation) for such canceled Interexchange Service that
     otherwise would have become due for the unexpired balance of the Service
     Commitment Period (but in no event less than zero); (ii) if the Service
     Commitment Period for the canceled Interexchange Service is longer than one
     (1) year and such cancellation becomes effective prior to completion of the
     first year of the Service Commitment Period, then the cancellation charge
     shall be an amount equal to the balance of the monthly Interexchange
     Service charges (then in effect at the time of cancellation) for such
     canceled Interexchange Service that otherwise would have become due for the
     unexpired portion of first year of the Service Commitment Period plus
     twenty percent (20%) of the balance of such monthly Interexchange Service
     charges for the remainder of the Service Commitment Period beyond the first
     year; and, (iii) if the Service Commitment Period for the canceled
     Interexchange Service is longer than one (1) year and such cancellation
     becomes effective after completion of the first year of the Service
     Commitment Period, then the cancellation charge shall be an

                          Page 18 of 27                             CONFIDENTIAL
                                                                    ------------

     amount equal to twenty percent (20%) of the balance of the monthly
     Interexchange Service charges (then in effect at the time of cancellation)
     for such canceled Interexchange Service that otherwise would have become
     due for the unexpired portion of the Service Commitment Period. It is
     agreed that WilTel's damages in the event Service is canceled shall be
     difficult or impossible to ascertain. The provisions provided for in this
     Section 11 (A) are intended, therefore, to establish liquidated damages in
     the event of cancellation and are not intended as a penalty.

     (B)  In the event of any cancellation described in Section 11 (A), Customer
     shall also pay WilTel an amount equal to any termination charges, expenses,
     fees or penalties incurred by WilTel due to cancellation of Local Access
     plus any other reasonable costs, expenses or additional charges incurred in
     accordance with Sections 8 and 10.

     (C) The foregoing to the contrary notwithstanding, and upon thirty (30)
     days prior written notice, either Customer or WilTel shall have the right,
     without cancellation charge or other liability, to cancel an affected
     portion of the Service, if any material rate or term contained herein and
     relevant to the affected Service is substantially changed by order of the
     highest court of competent jurisdiction to which the matter is appealed,
     the Federal Communications Commission, or other local, state or federal
     government authority.

     (D)  Customer may terminate this Agreement and all Services provided
     hereunder upon any material breach or material default by WilTel hereunder
     which breach or default is not cured within fifteen (15) business days
     after notice to WilTel by the Administrator. In the event Customer
     terminates this Agreement pursuant to this Subsection (D), Customer will
     not be liable for any cancellation charges, penalties or other amounts
     except for payment for Services actually rendered by WilTel prior to the
     effective date of such termination.

     20.  FORCE MAJEURE:   If WilTel's or Customer's performance of this
Agreement or any obligation hereunder is prevented, restricted or interfered
with by causes beyond its reasonable control including but not limited to acts
of God, fire, explosion, vandalism, cable cut, storm or other similar
occurrence, any law, order, regulation, direction, action or request of the
United States government or state or local governments, or of any department,
agency,

commission, court, bureau, corporation or other instrumentality of any one or
more said governments, or of any civil or military authority, or by national
emergencies, insurrections, riots, wars, strikes, lockouts or work stoppages or
other labor difficulties, supplier failures, shortages, breaches or delays, then
the affected party shall be excused from such performance on a day-to-day basis
to the extent of such prevention, restriction or interference.  The affected
party shall use reasonable efforts under the circumstances to avoid or remove
such causes of non-performance and shall proceed to perform with reasonable
dispatch whenever such causes are removed or cease.   If such failure of
performance shall be for thirty (30) days or less, then the Service affected
thereby shall continue as-is but, upon receipt of a Customer request directed to
Customer's designated Customer Service Representative, a pro rata credit of the
charges for the affected Service shall be me; if for more than thirty (30) days,
then said pro rata credit shall continue, and the affected Service may be
canceled by either Customer or WilTel on thirty (30) days notice without
liability other than Customer's liability for payment for Service provided prior
to cancellation.

     21.  SERVICE WARRANTY; GENERAL LIMITATION OF LIABILITY; INDEMNITY:

     (A)  WilTel warrants that the Service will be provided to Customer in
     accordance  with  prevailing  telecommunications  industry  standards
     (hereinafter "Technical Standards") .  WilTel will use reasonable efforts
     under the circumstances to remedy any delays, interruptions, omissions,
     mistakes, accidents or errors in the Service (hereinafter "Defect" or
     "Defects") and restore the Service in accordance with the Technical
     Standards.  Following Start of Service, if Customer reports a Defect to
     WilTel at WilTel's Maintenance Control Center and WilTel is unable to
     restore the Service as warranted within one-half hour of such report,
     Customer shall, upon request directed to Customer's designated Customer
     Service Representative, receive a credit at the rate of 1/1440 of the
     monthly charges applicable to the affected Service for each half hour or
     major fraction thereof in excess of the first half hour that the affected
     Service fails to conform to the Technical Standards.  If a portion of the
     Service fails to conform to the Technical Standards at any time and over a
     period of thirty (30) days after written notice thereof by Customer to
     WilTel, Customer may terminate the affected portion of the Service without
     a cancellation charge. Customer's credit and termination rights shall not
     apply, however, in the event any Defect is caused or contributed to,

                                                                    ------------

      directly or indirectly, by any act or omission of Customer or its
      customers, affiliates, agents, representatives, invitees or licensees.

      (B) THE FOREGOING WARRANTY AND REMEDIES ARE EXCLUSIVE AND IN LIEU OF ALL
      OTHER WARRANTIES OR REMEDIES WITH RESPECT TO THE SERVICE PROVIDED, WHETHER
      EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT LIMITATION IMPLIED
      WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. IN
      THE EVENT OF ANY DEFECT IN THE SERVICE WHATSOEVER, NEITHER WILTEL OR ANY
      THIRD PARTY PROVIDER OR OPERATOR OF FACILITIES EMPLOYED IN THE PROVISION
      OF THE SERVICE SHALL BE LIABLE FOR ANY DIRECT, INDIRECT, CONSEQUENTIAL,
      SPECIAL, ACTUAL, PUNITIVE OR ANY OTHER DAMAGES, OR FOR ANY LOST PROFITS OF
      ANY KIND OR NATURE WHATSOEVER.

      (C) In the event parties other than Customer shall have use of the Service
      through Customer, then Customer agrees to forever indemnify and hold
      WilTel and any third party provider or operator of facilities employed in
      provision of the Service harmless from and against any and all claims,
      demands, suits, actions, losses, damages, assessments or payments which
      may be asserted by said parties, arising out of or relating to any Defect
      in the Service.


      22.  INTERSTATE INTEREXCHANGE SERVICE: Customer may use any Interexchange
Service provided under this Agreement only if such Interexchange Service is used
for carrying interstate telecommunications (i.e., telecommunications subject to
the jurisdiction of the Federal Communications Commission).  WilTel shall only
be obligated to provide the Interexchange Service described in a Service Order
(which has been accepted by WilTel) when Customer's interstate use of the
Interexchange Service is greater than ten percent (10%) of the total traffic on
special access lines comprising Local Access associated with the Interexchange
Service. WilTel shall not be obligated to make available Interexchange Service
on a circuit with end points within a single state or service on a circuit which
originates/terminates at points both of which are situated within a single state
unless Customer represents in writing that such Interexchange Service or
circuits shall be used to carry interstate telecommunications, or the state in
question permits the Interexchange service to be provided.  If it is determined
at any time that such Interexchange Service or circuit is subject to state
regulation, WilTel may (i) provide the Interexchange Service or circuit pursuant
to applicable state laws, regulations and tariffs, (ii) assign the Interexchange
Service or circuit to an affiliated company to be provided in accordance with

such affiliated company's tariff, or (iii) discontinue provision of the affected
Interexchange Service or circuit.

      23.  NOTICES:  Notices under this Agreement shall be in writing and
delivered to the person identified as the "Party to Receive Notices" at the Full
Business dresses of the parties as they appear herein or as otherwise provided
for by proper notice hereunder and the effective date for any notice under this
Agreement shall be the date of delivery of such notice, not the date of mailing.

      24.  USE OF SERVICE:  Upon WilTel's acceptance of a Service Order
hereunder, WilTel will provide the Service specified therein to Customer upon
condition that the Service shall not be used for any unlawful purpose.  The
provision of Service will not create a partnership or joint venture between the
parties or result in a joint communications service offering to any third
parties, and WilTel and Customer agree that this Agreement, to the extent it is
subject to FCC regulation, is an inter-carrier agreement which is not subject to
the filing requirements of Section 211 (a) of the Communications Act of 1934 (47
U.S.C. (S) 211(a)) as implemented in 47 C.F.R. (S) 43.51.


      25.  PROPRIETARY INFORMATION:  Customer and WilTel understand and agree
that the terms and conditions of this Agreement and all documents referenced
herein (including without limitation, invoices to Customer for Service provided
hereunder), communications between the parties regarding this Agreement or the
Service to be provided hereunder (including price quotes to Customer for any
Service proposed to be provided or actually provided hereunder), as well as such
information and price quotes relevant to any other agreement between the parties
are confidential as between Customer and WilTel and shall not be disclosed by
Customer or WilTel to any party other than the directors, officers and employees
of Customer or WilTel, whichever is applicable, or agents of Customer or WilTel,
whichever is applicable, who have specifically agreed to nondisclosure of the
terms and conditions hereof. Violation by Customer or WilTel or their agents of
the foregoing provision shall entitle the other party, at its option, to
terminate this Agreement without further obligation or liability. Customer and
WilTel further agree that any press release, advertisement or publication
regarding this Agreement, the Service provided hereunder or in which either
party is to be mentioned, will be submitted to the other party for its written

(A)  Customer will execute such other documents, provide such information and
affirmatively cooperate with WilTel, all as may be reasonably required by WilTel
and relevant to providing the Service. In particular, Customer accepts the
responsibility for providing WilTel with special access surcharge exemption
forms as may be required by local exchange telephone companies.

enforce or insist upon compliance with any of the terms or conditions of this
Agreement shall not constitute the permanent waiver of any term or condition of
this Agreement.

(C)  The provision of the Service will not create a partnership or joint venture
between the parties or result in a joint communications service offering to
third parties.

(D)  In the event suit is brought or an attorney is retained by either party to
enforce the terms of this Agreement or to collect any moneys due hereunder or to
collect money damages for breach hereof, the prevailing party as determined by
the court in which the suit is brought shall be entitled to recover, in addition
to any other remedy, reimbursement for reasonable attorneys' fees, court costs,
costs of investigation and other related expenses incurred in connection
therewith.

(E)  No subsequent agreement concerning the Service or modification to this
Agreement shall be binding upon the parties unless it is me in writing by an
authorized representative of Customer and Authorized Headquarters Representative
of WilTel Services.

(F)  This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors or assigns, provided, however,
that Customer shall not assign or transfer its rights or obligations under this
Agreement without the prior written consent of WilTel, which consent shall not
be unreasonably withheld, and further provided that any assignment or transfer
without such consent shall entitle WilTel to terminate the Service provided
hereunder at its option upon ten (10) days prior written notice.

      the Customer and WilTel Services hereby agree to negotiate with respect to
      any such invalid or unenforceable part to the extent necessary to render
      such part valid and enforceable.

           incurred for reasons other than Customer's expedite request, these
           charges will not be passed on to Customer.

3.  CHANGE OF REQUESTED SERVICE DATE CHARGES:

           These charges apply when a change of the Requested Service Date is
           the only Customer requested modification to the original Service
           Order relevant to the Service in question.  The amount of the charge
           depends on when in the stage of order processing Customer's request
           is made to WilTel and whether the Requested Service Date for the
           Service in question has been previously modified.  If the first
           request to change an IXC Requested Service Date is received more than
           ten (10) working days prior to the original Requested Service Date
           ("Standard Notice"), there will be no charge.  If the Requested
           Service Date has been changed once already, or if the request is made
           within ten (10) working days of the established Requested Service
           Date ("Short Notice"), the applicable charge will apply.  An ASR
           charge will be assessed whenever a change of Requested Service Date
           is made with respect to Service Orders pursuant to which WilTel is to
           act as agent to obtain Local Access. When Customer requests that a
           Requested Service Date be pushed out, the new Requested Service Date
           is to be within thirty (30) days of the previous Requested Service
           Date. If the new Requested Service Date is more than thirty (30) days
           following the previous Requested Service Date, or is unknown, the
           Service affected thereby will be deemed to be canceled by Customer
           and subject to applicable cancellation charges. In no event will
           WilTel be obligated to accept more than three (3) changes to a
           Requested Service Date, and as of the fourth (4th) such request the
           Service in question will be deemed to be canceled by Customer and
           subject to applicable cancellation charges. A change of Requested
           Service Date charge also applies when Customer requests an earlier
           Requested Service Date that does not require an expedited
           installation interval. If an expedited interval is required, the
           Order Expedite Charge supersedes the Change of Requested Service Date
           Charge. Customer will also be charged for any changes incurred by
           WilTel from third party providers of facilities or services relevant
           to Service affected by a change of Requested Service Date.

4.  CHANGE OF ORDER CHARGES:

           Change of Order Charges apply when Customer requests a modification
           to the information contained in a fully executed or binding Service
           Order prior to completion of installation of the circuit (ICOM) other
           than a change of Requested Service Date.  Administrative changes
           (e.g. billing address, contact, etc.) on IXC only orders will be made
           without charge.  There will be an ASR charge for Administrative
           Changes with respect to Service Orders pursuant to which WilTel is to
           act as agent to obtain Local Access.  Change of Order is defined as a
           change of Local Access Service type (voice grade to data grade or
           vice versa), change of transmission speed (speed of DS-0, e.g. 4.8 to
           9.6), transmission mode or termination interface, or to reflect a
           partial cancellation of the order. Change of Order Charges will not
           apply if the origination or termination city changes (i.e., changes
           of termination interface are permitted, e.g., WASH.CPT to WASH.ICC,
           but not changes in city, e.g., DLLS.SWB to HSTN.SWB). Order
           modifications outside this Change of Order definition will be deemed
           as Customer's cancellation of affected Service and as an order for a
           new Service which must be described in a Service Order.

           Charges for Change of Order are lower if the change is received prior
           to circuit engineering.  While the exact time of circuit engineering
           may vary, to afford a verifiable date, "pre-engineering" is defined
           as being within five (5) working days of the date the order was
           entered into the WilTel F&E system (i.e., WilTel's order processing
           system) for standard interval circuits.  All expedited orders are
           deemed to be in "post-engineering" two (2) working days after the
           order is entered into the F&E system.  IXC Change of Order Charges
           apply if the change necessitates a modification of the IXC portion of
           the circuit (e.g. change IXC from ESF to B8ZS or 56K/DSO to 56K DDS).
           Local Access ASR Change of Order

02/01/95                                                             Page 4 or 8
<PAGE>
 
           Charges apply if the change requires a change in a LAP ASR or that a
           new ASR be sent. For example, a change on a DS-0 order from 2-wire to
           4-wire local loops requires a new ASR, but does not require any
           change to the WilTel IXC. There would, therefore, be an ASR Change of
           Order charge, but not an IXC Change of Order charge. Charges apply
           per affected circuit or ASR, not per Service Order in which the
           affected Service (which may be comprised of multiple circuits one or
           more of which may be affected by the change order) was originally
           described.

5.  ORDER CANCELLATION CHARGES:

           Order Cancellation Charges apply for orders canceled prior to
           completion of installation (ICOM). These charges are applied in
           addition to any cancellation charges specified in the relevant
           Service agreement between WilTel and Customer or cancellation charges
           relevant to associated M13, DCS, Echo Cancellation equipment or
           incurred by WilTel from third party service providers. Cancellation
           charges apply per IXC and per ASR and differ by pre and post
           engineering. The definition of both pre-engineering and post-
           engineering are the same as under Change of Order Charges. Order
           Cancellation Charges are in addition to installation charges which
           will also apply with respect to orders canceled prior to ICOM.

6.  CHANGE OF SERVICE CHARGES:

           Change of Service charges apply to Customer orders for changes made
           after a circuit has completed installation (ICOM). Administrative
           changes, i.e., changes to Customer's files such as billing address,
           billing contact, etc., will only be charged on affected Service for
           which WilTel also administers relevant Local Access.  The Change of
           Service Charge will be applied per Local Access ASR. Changes to
           initial cross-connects requested by Customer are covered under Cross-
           connect Re-arrangement Charges.

           Re-engineering charges apply to orders that are re-engineered due to
           Customer requested change in Local Access Service type (e.g., 2-wire
           to 4-wire), transmission speed, transmission mode (e.g., AMI to
           B8ZS), IXC or Local Access termination location or terminating
           equipment (DACS, MUX, cross-connect, etc.). Changes which require
           only modification of Local Access, but do not affect relevant IXC
           (e.g. 2-wire loop to 4-wire loop) will only result in a charge for
           the ASR(s) required to effect the order. Any LAP charges or third
           party service provider charges incurred by WilTel because of a
           Customer requested change will be passed on to Customer.

7.  CROSS-CONNECT RE-ARRANGEMENT CHARGES:

           Cross-connect Re-arrangement Charges apply either when Customer
           requests additional cross-connects or changes to existing cross-
           connects after initial installation.  If a new cross-connect is part
           of a new WilTel IXC order (adding a DS-0 IXC to a DS-1 Fan-Out or a
           DS-1 IXC off an M13) no additional Cross-connect Re-arrangement
           Charge will apply since the IXC installation charge includes an
           initial cross-connect. When cross-connects are within the same piece
           of DCS equipment or M13, the charge is per lower level (transmission
           speed) circuit with a maximum per DCS or M13.

8.  ROLL-UP CHARGES:

           When permitted by terms of the relevant Service agreement between
           WilTel and Customer or as otherwise agreed to in a writing subscribed
           to by authorized representatives of Customer and WilTel, Customer
           requested upgrades of either multiple WilTel provided DS-0's to a new
           WilTel provided DS-1 IXC or Local Access circuit, or multiple WilTel
           provided DS-1's to a new WilTel provided DS-3 IXC or Local Access
           circuit, will be subject to a single lump-sum re-engineering and/or
           ASR charge, rather than a charge for the re-engineering of each of
           the existing

02/01/95                                                             Page 5 of 8
<PAGE>
 
           circuits individually. There is no charge for rolling an FT-1
           (Fractional DS-1) up to a full DS-1 IXC.

9.  ADDITIONAL INSTALLATION/MAINTENANCE CHARGES:

           Additional Installation and/or Maintenance Charges apply when
           Customer requests installation or circuit changes to be effected
           during non-business hours for Wiltel or when Customer requests a
           WilTel technician at the Customer premise for trouble that results
           from problems in non-WilTel provided facilities.  These charges also
           apply when Customer requests and WilTel agrees to perform other
           engineering, design or activities which are not provided by WilTel as
           part of its then standard design and installation of Service.

10. CROSS-CONNECT CHARGES:

           SERVICE DESCRIPTION/APPLICATION:

           A cross-connect is an electrical connection made between two DS-1
           circuits on a DSX-1 cross-connect panel or two DS-3 circuits on a 
           DSX-3 cross-connect panel in a WilTel or WilTel designated third
           party Point of Presence (POP).

           CHARGES:

           Cross-connect Charges are determined by the level and type of
           facilities being connected. Initial cross-connects will be provided
           at no additional charge when there is an associated WilTel provided
           IXC of the same level (i.e. DS-1 cross-connect with associated WilTel
           provided DS-1 IXC). If Customer places a firm cross-connect order
           simultaneously with a corresponding Service Order, WilTel agrees to
           waive the monthly recurring cross-connect charges; provided, however,
           rearrangement and changes to existing cross-connects will be subject
           to the cross-connect charges set forth herein. Charges for additional
           cross-connects after initial installation or reconfiguration of
           existing cross-connects are covered under Cross-Connect Re-
           Arrangement Charges. For cross-connects within a DACS or MUX, see
           respectively the Digital Cross-Connect Service Description and
           Charges and M13 Multiplexing Service Description and Charges.

11.  M13 MULTIPLEXING (DS-3 TO DS-1) CHARGES:

           SERVICE DESCRIPTION/APPLICATIONS:

           This Service provides M13 multiplex equipment (MUX) in a WilTel or
           WilTel designated third party POP to perform the function of deriving
           up to twenty-eight (28) DS-1 level circuits out of a single DS-3
           level circuit. M13 Multiplexing Service is only available at WilTel
           approved M13 locations.

           CHARGES:

           M13 Multiplexing Charges are applied on a per M13 basis and
           automatically apply when FT-3 (fractional DS-3) Service is provided.
           M13's will not be provided without an associated WilTel provided full
           DS-3 or FT-3 IXC. Initial cross-connects necessary to establish this
           Service are included in the M13 Multiplexing Charges. Charges for
           additional cross-connects after initial installation or
           reconfiguration of existing cross-connects are covered under Cross-
           Connect Re-Arrangement Charges. Charges for DS-3 to DS-1 Drop &
           Insert applications are applied based upon the number of M13's
           utilized. When Customer requires that WilTel be able to isolate and
           test individual DS-1 channels on a DS-3 IXC connected to M13
           multiplexing equipment, the DS-3 Sub-Rate Maintenance Charge will
           also apply. WilTel will also supply Customer one (1) Ml-3
           Multiplexer, at no cost to Customer, for each DS-3 level On-Net
           circuit ordered by Customer, provided such Ml-3 Multiplexer is
           ordered simultaneously with the

02/01/95                                                            Page 6 of 8
<PAGE>
 
           applicable Service Order for such DS-3 circuit. The preceding
           sentence shall not apply, however, in the event Customer reconfigures
           the DS-3 level circuits.

 12.  DIGITAL CROSS-CONNECT SERVICE (DCS or DACS) CHARGES:

           SERVICE DESCRIPTION/APPLICATIONS:

           Digital Cross-Connect Service (DCS or DACS) can be used within the
           WilTel Network for two basic applications: DS-1/DS-0 Drop & Insert
           Service or DS-1/DS-0 Fan-Out (See, attached diagrams for these two
                                         ---
           applications).  DCS equipment located in a WilTel designated POP is
           used to electronically multiplex-demultiplex DS-0 (VF/DDS) level
           channels from a DS-l level circuit and then electronically cross-
           connect those DS-0 channels to either a DS-0 circuit or to a
           different DS-1 circuit. DCS is WilTel's alternative to the use of DS-
           l/DS-0 channel banks and VF/DDS electrical distribution frames within
           WilTel designated POP's. DCS Service is only available at WilTel
           approved DCS locations.

           CHARGES:

           The charge for DCS is applied per associated WilTel DS-1 IXC or
           corresponding Local Access DCS termination. WilTel is under no
           obligation to provide DCS for use in conjunction with transmission
           services not provided by WilTel. Initial DS-0 cross-connects within
           the DCS necessary to establish this Service are included in the
           charge.  Charges for additional cross-connects after initial
           installation or reconfiguration of existing cross-connects are
           covered under Cross-Connect Re-Arrangement Charges.  In cases where a
           DS-1 IXC is terminated in DCS for connection to VF or DDS (DS-0
           level) Local Access facilities, or when DCS is used for DS-1 Drop &
           Insert (DS-0 cross-connections between DS-1 IXC's), the DS-1 Sub-Rate
           Maintenance Charge will also apply.

13. SUB-RATE MAINTENANCE CHARGES:

           SERVICE DESCRIPTION/APPLICATION:

           Sub-Rate Maintenance Charges are applied to recover and compensate
           WilTel for the additional administration and maintenance costs
           incurred by WilTel when higher capacity service (DS-3 and DS-1) is
           broken down into lower level channels which require individual
           tracking, testing and maintenance. Sub-Rate Maintenance will
           automatically be provided by WilTel on WilTel provided DS-3 IXC with
           M13 MUX and WilTel provided DS-1 IXC with attached DCS unless
                                                                  ------
           Customer signs a waiver form acknowledging that WilTel will not be
           responsible for the testing and Maintenance of associated lower level
           IXC channels. DS-3 Sub-Rate Maintenance Charges will apply when a DS-
           3 IXC has associated M13 MUX equipment and WilTel is responsible for
           testing and maintaining individual DS-1 channels within the DS-3 IXC.
           DS-1 Sub-Rate Maintenance Charges will apply when DS-1 IXC is
           connected to multiple DS-0 level (VF or DDS) Local Access channels
           either through WilTel DCS or through LAP provided D4 Channel Banks.
           DS-1 Sub-Rate Maintenance Charges will also apply when WilTel DCS
           equipment is used to Drop & Insert channels between DS-1 IXC's and
           WilTel is responsible for testing and maintaining individual DS-0
           channels within a DS-1 IXC.

           CHARGES:

           Pricing for DS-3 and DS-1 Sub-Rate Maintenance are applied per sub-
           rate Local Access channel or IXC end with a maximum charge per DCS or
           M13 MUX.  Where M13 or DCS connections are to be made between
           different Service provided to two different WilTel customers, the
           customer ordering the connection(s) will be charged by WilTel for the
           applicable Sub-Rate Maintenance.

02/01/95                                                            Page 7 of 8
<PAGE>
 
14. ECHO CANCELLATION CHARGE:

           SERVICE DESCRIPTION/APPLICATION:

           With this service option, WilTel will provide echo cancellation
           equipment on Customer's WilTel provided DS-0 or DS-1 IXC's necessary
           to cancel the echo caused by the total cumulative physical length of
           transmission path (route miles) traveled by the circuit from
           origination to termination.  Echo cancellation applies only to voice
           applications of DS-0 and DS-1 Service. WilTel will employ echo
           cancellation equipment free of charge on DS-0 and DS-1 IXC's that
           are, by WilTel design, greater than 800 route miles.  In cases where
           Customer requested routing or other Customer (directly or indirectly)
           controlled circumstances cause the circuit length to exceed 800 route
           miles, Customer will be charged for Echo Cancellation Service. Echo
           Cancellation Service provided by WilTel on a temporary basis due to a
           re-route around WilTel Network blockage or damage will not be charged
           to Customer.

           CHARGES:

           Echo Cancellation Charges are applied per canceller and per
           associated DS-0 or DS-1 IXC provided by WilTel.

                                   AMENDMENT

     This Amendment (the "AMENDMENT") is made and entered into as of the 1st day
of April, 1996 (the "EFFECTIVE DATE") to that certain Carrier Digital Services
Agreement dated as of September 1, 1995 (the "AGREEMENT") made by and between
WorldCom Network Services Inc. d/b/a WilTel ("WILTEL") and (i) Associated
Communications Companies of America ("ACCA"), and (ii) the individual1 members
of ACCA which are listed on Appendix A hereto (individually referred to as a
"MEMBER"). In the event of any conflict between the terms of the Agreement and
the terms of this Amendment, the terms of this Amendment shall control.
References to "CUSTOMER" shall refer collectively to ACCA and to all ACCA
Members and to each Member individually:

                               R E C I T A L S:

     A.  ACCA has added two (2) members, Consolidated Communications, Inc.
("CNI") and U.S. Long Distance ("USLD"), as Members ,

     B.  Pursuant to the Agreement, ACCA desires to allow CNI and USLD to
purchase Interexchange Services under the Agreement.

     C.  WilTel agrees to add CNI and USLD as Members under the Agreement
pursuant to the terms and conditions contained herein.

     NOW THEREFORE, in consideration of  good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agrees as
follows:

     1.  ADDITION OF MEMBERS: Each of CNI and USLD have been previously
provided a copy of the Agreement and have read and understand the terms and
conditions contained therein. By execution of this Amendment , each of CNI and
USLD agree to be liable under such Agreement as if they were each an original
party to the Agreement, including without limitation, the requirement imposed on
all Members to allocate a Delinquent Member's portion of Customer's Commitment
among all other Members as described in Section 18 of the Agreement. Further, by
execution of this Amendment, all other Members consent to the addition of CNI
and USLD as parties to the Agreement.

     2.  PRIOR AGREEMENT: The parties acknowledge that there currently exists a
Carrier Digital Services Agreement between CNI and WilTel (the "PRIOR CNI
AGREEMENT") which provide for a take-or-pay commitment of [_______]from the
Effective Date of this Amendment through and including March 31, 1997. As of the
Effective Date of this Amendment, the Prior CNI Agreement will be canceled and
of no further force or effect and the parties to the Prior CNI Agreement shall
be released from all liability thereunder with the exception of certain
obligations arising under the Prior CNI Agreement which are intended to survive,
such as, payment for services provided thereunder and rights of confidentiality
and indemnity. Neither ACCA, nor any individual Member of ACCA other

than CNI, shall have any liability or obligation whatsoever with respect to the
Prior CNI Agreement.

     3.   CUSTOMER'S COMMITMENT: The parties agree to substitute Subsection 9(A)
of the Agreement to read in its entirety as follows:

     (A)  Commencing as of the Effective Date and continuing through the end of
     the Term (the "COMMITMENT PERIOD") Customer agrees to maintain, on a take-
     or-pay basis, Monthly Recurring Interexchange Service Charges of at least
     $553,450 ("CUSTOMER'S COMMITMENT"). It is further understood by the parties
     that certain Members have individually committed for a certain portion of
     Customer's Commitment as further described in the Amended and Restated
     Commitment Schedule. Provided, however, nothing contained herein shall be
     construed as to make ACCA directly liable to WilTel for the Monthly
     Recurring Interexchange Service Charges of any individual Member or to make
     any Member directly liable to WilTel for the Monthly Recurring
     Interexchange Service Charges of any other individual Member.

     4.   LETTER OF CREDIT: In accordance with Subsection 17(C) of the
Agreement, upon execution of this Amendment, CNI agrees to provide WilTel with a
letter of credit equal to $103,450 unless such requirement is waived by WilTel
or some other security arrangement acceptable to WilTel is agreed to by the
parties.

     5.   OTHER TERMS AND CONDITIONS: Except to the extent specifically modified
by this Amendment, the remaining terms and conditions contained in the Agreement
shall be in full force and effect through the remainder of the Term.

     6.   COUNTERPARTS: This Amendment may be executed in multiple counterparts,
each of which shall be deemed an original and all of which together shall
constitute one and the same instrument.

     IN WITNESS WHEREOF, the parties have executed this Amendment as of the date
first written above.

                                                                ------------

          end of the Term (the "Commitment Period"), Customer agrees to
          maintain, on a take-or-pay basis, Monthly Recurring Interexchange
          Service Charges of at least [______] ("Customer's Commitment"). It is
          further understood by the parties that certain Members have
          individually committed for a certain portion of Customer's Commitment
          (hereinafter referred to as a "Member's Portion") as further described
          in Section 17 below. Provided, however, nothing contained herein shall
          be construed as to make ACCA or any Member directly liable to WitTel
          for the Monthly Recurring Interexchange Service Charges of any other
          Member.

          (B)  If, in any month during the Commitment Period, the aggregate of
          all of the Members' actual Monthly Recurring Interexchange Service
          Charges does not equal at least the Customer's Commitment, then WilTel
          will determine which Member (or Members) (a "DELINQUENT MEMBER") has
          not satisfied its respective Member's Portion as shown in the Amended
          and Restated Commitment Schedule described in Subsection 17(B). In
          such case and only for such month(s), the Delinquent Members agrees to
          pay WilTel the difference between its actual Monthly Recurring
          Interexchange Service Charges and its respective Member's Portion, if
          any (the "MONTHLY DEFICIENCY CHARGE"). Monthly Deficiency Charges, if
          any, determined in accordance with this Subjection (B) shall be due at
          the same time service charges are due hereunder.

          (C)  The parties hereby specifically agree that the provisions
          contained herein describing a deficiency charge represents a mutual
          good faith estimate of, and bears a reasonable relationship to, the
          actual damages to WilTel in the event of such deficiency and do not
          represent a penalty of any kind, and that such deficiency charge is an
          obligation of ACCA and the Members subject to specific performance.

          (D)  For purposes of this Agreement, "Monthly Recurring Interexchange
          Service Charges" will not include pro-rated charges for Interexchange
          Service, Local Access charges, Ancillary Service charges, Additional
          Charges (as defined below), other recurring or non-recurring charges
          for space, facilities or any other charges other than those charges
          identified by the relevant WilTel invoice as monthly recurring
          interexchange service charges for private line service.

               (E) In the event Customer submits a firm Service Order for DS-l
               or DS-3 level On-Net Service (other than orders submitted under
               Sections 11 or 12 below) and WilTel can not deliver Service
               within thirty (30) business days or some other longer interval
               agreed to by Customer, and Customer orders and is provided such
               Service by another carrier, then solely for purposes of
               determining if Customer has met Customer's Commitment described
               in Subsection (A) above, WilTel agrees to include an amount equal
               to WilTel's Monthly Recurring Interexchange Service Charges for
               such Service times the number of months such Service is actually
               installed by the other carrier. Upon request by WilTel, Customer
               agrees to provide adequate documentation reasonably acceptable to
               WilTel to substantiate Customer's ordering and being provided
               Service under this Subsection from another carrier.

          (C)  The Base Rate for Multiple DS-l level Interexchange Service
          ("Multiple DS-1 Service") will be the DS-l Interexchange Service rates
          described in Subsection (B) above. Multiple DS-l Service between and
          among WilTel On-Net Cities and/or WilTel Extended Cities ordered
          solely by one Member (i.e., Members may not allocate Service under
          this Subsection (D)) will be subject to the discounts described below
          provided all of the following conditions are met:

               (i)   Customer orders at least six (6) DS-l circuits between or
          among On-Net Cities and/or WilTel Extended Cities at one time (the
          "Circuit Package");

               (ii)  the Requested Service Dates relevant to all of the DS-1s in
          the Circuit Package are subject to WilTel's standard intervals and, if
          more than one date is requested, the dates are within the same thirty
          (30) day period; and

               (iii) the Service Commitment Period for each of the DS-ls in
          question is twelve (12) months.

          In the case of a new initial Circuit Package comprised exclusively of
          existing DS-1s, the Multiple DS-1 Service discount and twelve (12)
          month Service Commitment Period will commence as of the second monthly
          billing period following the month in which the Service Order therefor
          is submitted. If Customer desires to create a larger Circuit Package
          or create an initial Circuit Package from existing DS-ls and
          incremental new DS-ls (e.g., take a Circuit Package of 6 to a Circuit
          Package of 10 DS-ls; or, create an initial Circuit Package of at least
          6 DS-ls with at least 4 existing DS-1s plus an additional incremental
          2 DS-ls), Customer will first identify all DS-ls to be in the
          resulting Circuit Package. All circuits within the resulting Circuit
          Package will be subject to a twelve (12) month Service Commitment
          Period commencing as of the date the last circuit comprising the

          package is installed. If through the creation of a larger Circuit
          Package existing DS-ls should be subject to a greater level of
          discount, the applicable discount shall commence for the existing 
          DS-ls as of the date the last circuit in the larger Circuit Package in
          installed, and the applicable discount for each new incremental DS-l
          relevant to the larger Circuit Package shall commence as of Start of
          Service for each such incremental DS-l.

          include (i) "Monthly Recurring Interexchange Service Charges" (as

          special feature charges such as Authorization Codes or CDR Tapes, or
          any other charges other than those identified by the relevant WilTel
          invoice as Switched Service charges). The Monthly Spending Level will
          be determined at the end of each month and will be based on WilTel's

     -----------

     If any dispute referred to the Intercompany Review Board, as determined by 
     DCI and IFN, has not been resolved within ten working days after the date

                                      -5-
<PAGE>
 
     of referral to the Board, the Parties may agree to submit the dispute to
     binding arbitration. If the Parties do agree to submit a dispute to binding
     arbitration, the dispute shall be decided by a majority of three
     arbitrators selected in accordance with the procedures set forth herein.
     An agreement to arbitrate shall be enforceable under then prevailing law
     and decision rendered by a majority of the arbitration panel shall be final
     and a judgement may be entered upon it in accordance with the applicable
     law in any court of competent jurisdiction.

     An agreement to arbitrate shall be made within six months after demand that
     the dispute be referred to the Intercompany Review Board.

     Unless otherwise agreed to in writing by the Parties, upon an agreement to
     arbitrate, each Party shall designate an arbitrator within five working
     days. The two designated arbitrators shall then select a third arbitrator
     to complete the full arbitration panel within ten working days, or as
     otherwise agreed.

     The arbitration panel shall commence hearings within sixty days of
     selection unless the Parties agree upon or the arbitration panel orders a
     delayed schedule of hearings. Either party may send requests to compel
     document production from the other. Disputes concerning the scope of
     document production from the other. Disputes concerning the scope of
     document production and enforcement of the document requests shall be
     subject to agreement by the Parties or may be ordered by the arbitration
     panel to the extent economical and reasonable. All discovery requests shall
     be subject to the proprietary rights and rights and privilege of the
     Parties, and the arbitration panel shall adopt procedures to protect such
     rights. Except where contrary to the provisions set forth in this
     Agreement, the rules of the American Rules of Arbitration ("AAA") shall be
     applied to all matters of procedure, including discovery; PROVIDED,
     HOWEVER, that the arbitration need not be conducted under the auspices of
     the AAA, in which event the fee schedule of the AAA shall not apply. The
     arbitration panel may obtain independent legal counsel to aid in the
     resolution of legal questions presented in the course of arbitration to the
     extent that such counsel is considered absolutely necessary to the fair
     resolution of the dispute, and to the extent that is economical to do so
     considering financial consequences of the dispute.

     If the arbitrators selected by each Party cannot agree upon the third
     arbitrator within the time limits set by this Agreement, either Party may
     apply to any court having jurisdiction over this Agreement to select the
     neutral arbitrator. If either Party fails to appoint an arbitrator within
     the time period set forth, the other Party may apply to any court having
     jurisdiction over this Agreement to compel arbitration, and that court
     shall be empowered to select the arbitrator.
     
     If either Party fails or refuses to appear at and participate in an
     arbitrations hearing after due notice, the arbitration panel may hear and
     determine the controversy upon evidence produced by the appearing Party.

     Arbitration costs (i.e., neutral arbitrator, transcript and hearing room)
     shall be borne equally by each Party. However, each Party shall pay the
     expenses of its representative on the arbitration panel and of presenting
     its own case

                                      -6-

<PAGE>
 
     (i.e., attorneys, witnesses, and document preparation).

     Arbitration provided by this Section shall not be an exclusive remedy for
     the enforcement of the rights and obligations of the Parties as contained
     in this Agreement, and shall be available only if the Parties agree to
     submit a specific dispute (or disputes) to binding arbitration. The
     provisions regarding arbitration in this Section shall be activated only
     after further agreement to submit to arbitration and shall not preclude
     either Party from seeking relief with respect to any dispute against the
     other Party in any court having jurisdiction; PROVIDED, HOWEVER, that if
     the Parties do agree to arbitration of the dispute in accordance with this
     Section, the arbitrator's decision shall be final and binding upon the
     Parties, and shall be subject to review only as provided by law.

     During the course of dispute resolution pursuant to the provisions of this
     Section, and unless otherwise agreed in writing, the Parties shall continue
     to provide service, continue to make payments, and honor all other
     commitments in accordance with this Agreement.

           Party's subcontractors, under workers' compensation or similar
           statutes. Each Party agrees to defend any such suit brought against
           the other for any such liability, claim, or demand. Each Party agrees

           -----------------------
           shall not release either Party from any liability which at the time
           of termination has already accrued to the other Party or which

                   GENERAL TERMS AND CONDITIONS FOR RESELLER
                                  AGREEMENTS


1.   SERVICES TO BE PROVIDED BY T-NET. T-NET shall provide to Reseller, and
     --------------------------------
     Reseller shall pay T-NET for, the long distance services ("SERVICE" or
     "SERVICES") set forth in the "SERVICES TO BE PROVIDED BY T-NET" portion of
     the Order Information Section of this Agreement and as set forth in service
     requests signed by Reseller which are acceptable to T-NET ("SERVICE
     REQUEST"). Each Service Request shall set forth, at a minimum, the
     following: (i) the type of access into the T-NET network (i.e., either via
     switched access or dedicated T-1 access); (ii) ANI information relevant to
     the Services; (iii) the Requested Start Date as defined below; (iv) the
     Reseller billing address; and (v) any other pertinent information relevant
     to the Services. It is understood that Reseller is purchasing such Services
     from T-NET for the sole purpose of reselling such Services to its customers
     (hereinafter, "END USERS" or "END USER SUBSCRIBERS"). Reseller is
     responsible for ordering and for paying for any access facilities to
     connect Reseller's facilities to T-NET's network.

     If T-NET accepts a Service Request, T-NET shall start providing the
     Services to an End User of Reseller on the earlier of (i) the service date
     requested by Reseller for such End User ("REQUESTED START DATE") set forth
     in the Service Request, or (ii) the date the Service is made available to
     such End User and is used ("SERVICE START DATE").

2.   TERM. The term of this Agreement shall start on the date of full execution
     ----
     of this Agreement ("EFFECTIVE DATE") and it shall continue starting with
     the first full T-NET monthly billing cycle after T-NET initiates Service to
     the first End User of Reseller through the number of months set forth in
     the "INITIAL TERM" portion of the Order Information Section of this
     Agreement ("INITIAL TERM"). Either party may terminate this Agreement at
     the end of the Initial Term by providing thirty (30) days' prior written
     notice. If no such notice is given, this Agreement shall continue after the
     Initial Term until terminated by either party providing the other with
     thirty (30) days' prior written notice. The term "TERM" as used herein
     shall mean the Initial Term plus any subsequent period of time during which
     this Agreement continues beyond the end of the Initial Term. If T-NET shall
     have undertaken efforts to provide Services prior to the date of full
     execution of this Agreement, the provisions of this Agreement shall apply
     retroactively with respect to such efforts and such Services.

     If T-NET has not received any traffic under this Agreement within sixty
     (60) days after the Effective Date, T-NET shall have the right to terminate
     this Agreement upon written notice to Reseller.

3.   RATES AND TAXES.
     ---------------

     3.1  RATES AND CHARGES. For a particular End User, the Reseller shall pay
          -----------------
          T-NET any monthly, usage and one-time charges set forth in the "RATES"
          portion of the Order Information section of the Agreement starting on
          the date which is the earlier of (i) the Requested Start Date, or (ii)
          the Service Start Date. Each international call shall be billed in six
          (6) second increments with a thirty (30) second minimum. Each domestic
          inbound call shall be billed in six (6) second increments with a
          thirty (30) second minimum and each domestic outbound call shall be
          billed in six (6) second increments with a six (6) second minimum. T-
          NET's international rates are subject to change upon notice to
          Reseller. If Reseller requests T-NET to expedite the delivery of the
          Service, and T-NET agrees to such request, T-NET shall pass through
          the actual charges assessed T-NET by any supplying parties (e.g., the
          local access providers) for such request.

     3.2  TAXES. The rates and charges set forth in this Agreement do not
          -----
          include any applicable federal, state, or local taxes, fees and
          surcharges. Unless Reseller provides to T-NET a valid exemption
          certificate, Reseller shall pay such applicable taxes, fees and
          surcharges upon receipt of an itemized invoice therefor.

4.   PAYMENT FINANCIAL REPORTS AND SECURITY DEPOSITS.
     -----------------------------------------------

     4.1  PAYMENT. T-NET shall provide monthly invoices to Reseller covering
          -------
          designated T-NET monthly billing periods which shall be due and
          payable within the Payment Period set forth in the Order Information
          section of this Agreement. T-NET shall provide Reseller with the call
          detail records applicable to each month's invoice in a format
          acceptable to T-NET. All payments for the Services shall be made to
          Cable & Wireless, Inc., and as determined by T-NET, either by check
          and mailed to the address set forth on the first page of the Reseller
          Agreement to the Attention of Mr. Scott Sorge, Alternate Channels or
          by wire transfer to the account designated below.

          If the Order Information section of this Agreement indicates that
          estimated payments are required, T-NET shall notify the Reseller on
          the last day of the "ESTIMATED USAGE PERIOD," or if such day is not a
          business day, on the next business day, as to T-NET's estimate of the
          charges incurred by the Reseller during such period. The Reseller
          shall pay T-NET such estimated amount ("ESTIMATED PAYMENT") no later
          than the "ESTIMATED PAYMENT DUE DATE". At the end of a T-NET monthly
          billing period, T-NET shall provide an invoice for the usage charges
          actually incurred that month less that month's Estimated Payment,
          provided, however, that if a minimum monthly payment obligation
          applies for that month and such minimum has not been met, then the
          invoice amount shall be that month's minimum payment

                   GENERAL TERMS AND CONDITIONS FOR RESELLER
                                  AGREEMENTS

          obligation less that month's Estimated Payment. The Reseller shall
          pay the invoiced amount within the Payment Period.

          A late payment charge shall be applied on balances that remain unpaid
          after the Payment Period in the amount of the lesser of (a) 1 1/2%
          (one and one-half percent) per month of the amount of the late payment
          starting from the day following the end of the Payment Period, or (b)
          the maximum amount allowed under applicable law. The Reseller must pay
          all invoices when due; and any questions which the Reseller may have
          concerning an invoice must be brought to T-NET's attention within
          forty-five (45) days of the invoice date. Customer shall be liable to
          T-NET for any and all costs and/or expenses incurred directly or
          indirectly, including reasonable attorney's fees and expenses, in
          collection of any amounts due.

          If so indicated in the Order Information section of this Agreement,
          all payments by the Reseller will be made via wire transfer (in
          immediately available funds) to Mellon Bank, 3 Mellon Bank Center,
          Room 153-2718, Pittsburgh, PA 15259-0001, ABA #0430-00261/Account
          #1705643. Each such wire transfer shall designate: (i) "Cable &
          Wireless, Inc." as the beneficiary, and (ii) "T-NET in the "Other
          Beneficiary Information" or "OBI" section thereof.

     4.2  Financial Reports. If the Order Information section of this Agreement
          -----------------
          indicates that financial reports are required, within thirty (30) days
          after the end of each calendar quarter, the Reseller shall provide T-
          NET with a written report updating the Reseller's financial status
          ("QUARTERLY REPORT"), and within ninety (90) days after the end of
          each calendar year, the Reseller shall provide T-NET with an audited
          annual report. Each Quarterly Report shall contain, at a minimum, an
          updated balance sheet and income statement. The Reseller represents
          and warrants that no Quarterly Report shall contain any material
          misstatement or omission bearing on the Reseller's financial
          condition.

     4.3  Security Deposits. If the Order Information section of this Agreement
          -----------------
          indicates that security deposits are required, the "INITIAL SECURITY
          DEPOSIT" amount shall be provided prior to any initiation of Service.
          Thereafter, if requested in writing by T-NET, the Reseller shall add
          additional amounts to the Initial Security Deposit such that the total
          amount of security deposit being held by T-NET at all times is at
          least equal to the "CONTINUING SECURITY DEPOSIT AMOUNT". The Reseller
          shall provide any such required additional amounts within five (5)
          business days after receiving T-NET's written request.

          If, at any time during the term of the Agreement, T-NET determines
          that there has been a materially adverse change in the Reseller's
          financial condition as compared with the equivalent period of time
          immediately prior to the Effective Date, T-NET may require Reseller to
          provide a security deposit or an additional security deposit in an
          amount to be determined by T-NET. The Reseller shall provide any such
          required amounts within five (5) business days after receiving T-NET's
          written request therefor.

          Each required security deposit shall be either in cash (paid by check
          or wire transfer) or an irrevocable letter of credit in a form and
          from a financial institution acceptable to T-NET.

          T-NET shall refund or release, as applicable, any security deposit it
          is holding (plus, if the security deposit is in the form of cash,
          accrued interest at the applicable rate set by regulation of the state
          in which T-NET invoices the Reseller, or if no such rate is set by
          regulation. T-NET's then-prevailing interest rate for security deposit
          refunds) if the following conditions are met by the Reseller: (i) for
          the entire "DEPOSIT RELEASE PERIOD", the Reseller pays T-NET in full
          when each payment is due; and (ii) T-NET determines that the
          Reseller's Quarterly Reports covering the Deposit Release Period
          indicate that the Reseller's financial condition has had no materially
          adverse change as compared to the equivalent period of time
          immediately prior to the start of the Deposit Release Period. If the
          above conditions are not met, the security deposit shall be refunded
          or released, as applicable, at the end of the Term less any amounts
          that may be due and owing to T-NET at such time.

5.   MINIMUM PAYMENT OBLIGATIONS. If the total amount of usage charges incurred
     ---------------------------
     by the Reseller in any month is less than the amount of the then-
     applicable minimum monthly payment obligation set forth in the Order
     Information section of this Agreement, then in addition to paying for its
     actual usage that month, the Reseller shall pay (as an underutilization fee
     and not as a penalty) a shortfall charge equal to the difference between
     (i) the actual usage charges incurred that month, and (ii) the amount of
     the then-applicable minimum monthly payment obligation. If this Agreement
     remains in effect after the Initial Term, the minimum monthly payment
     obligation for each subsequent T-NET monthly billing period shall be equal
     to the amount of the minimum monthly payment obligation for the last T-NET
     monthly billing cycle of the Initial Term.

     --------------------------------------
     (i) all charges incurred by T-NET to change the PIC of End Users to
     Reseller, (ii) all charges incurred by T-NET to change End Users back to
     their previous PIC arising from disputed transfers plus an administrative
     charge equal to twenty percent (20%) of such charges; (iii) an
     administrative charge of $50.00 per disputed ANI if Reseller does not
     provide to T-NET a valid non-disputed LOA within five (5) business days
     from T-NET's request, and (iv) any other damages suffered by or awards
     against T-NET resulting from disputed transfers.

     Reseller shall, within two (2) business days from receipt of such request,
     provide a copy to T-NET of any LOA or such other requested information by 
     T-NET to confirm Reseller's compliance with Reseller's obligations set
     forth herein.

            notified Reseller of a problem with the Services including, but not
            limited to, excess noise, echo or loss of Service. Reseller shall
            cooperate with T-NET in resolving service-related issues and shall

                                  AGREEMENTS

           prohibited, either on a temporary or permanent basis, from conducting
           its telecommunications operations in a given jurisdiction, in
           addition to any other remedies available to T-NET, Reseller shall
           immediately so notify T-NET by facsimile, and send via regular mail
           the original of such written notice to T-NET within twenty-four (24)
           hours of such prohibition.

11.  SUSPENSION AND TERMINATION OF SERVICE.
     -------------------------------------

     11.1  Suspension of Services for Non-Payment. In addition to any other
           --------------------------------------
           remedies available to T-NET, if the Reseller fails to pay any invoice
           in full (including any late payment charges, if any) or other demand
           for payment hereunder when due, T-NET shall have the right, at its
           option, after providing Reseller two (2) days' prior written notice

           of the Services to Reseller and its End Users including, without
           limitation, the right to withhold call detail records until such time
           (as designated in the Suspension Notice) as Reseller has paid T-NET
           in full all the charges then due to T-NET, including any late payment
           charges, if any. If Reseller makes such payment on or before the date
           set forth in the Suspension Notice, T-NET shall reinstate such
           Services only when Reseller provides T-NET with satisfactory
           assurance of Reseller's ability to pay for the Services (i.e.,
           deposit, letter of credit or other means acceptable to T-NET) and
           Reseller pays in advance any costs associated with the suspending and
           reinstating such Services. If Reseller fails to make its required
           payment by the date set forth in the Suspension Notice, this
           Agreement and the Services shall be deemed, without any further
           action by either party, to have terminated effective as of the date
           of suspension by T-NET. In the event of such termination, the
           obligations set forth in Section 11.3.3(i), (ii) and (iii) below
           shall apply to Reseller.

     11.2  Termination of Agreement by Reseller. Prior to the end of the Term,
           ------------------------------------
           the Reseller may terminate this Agreement in its entirety by
           providing T-NET with sixty (60) days' advance written notice. In such
           event, the Reseller shall pay T-NET the amounts set forth in Section
           11.3.3(i) and (ii) below.

     11.3  Termination of Agreement by T-NET. In addition to any other remedies
           ---------------------------------
           available, T-NET may immediately terminate this Agreement in the
           event of a breach by Reseller which includes, but is not limited to,
           the following:

           11.3.1   Without notice in the event any of the following occurs: (i)

                    bankruptcy; (ii) initiation of proceedings against Reseller
                    in involuntary bankruptcy which are not dismissed within
                    sixty (60) days of initiation; (iii) the appointment of a
                    receiver or trustee for Reseller; (iv) a general assignment
                    for the benefit of Reseller's creditors; (v) Reseller's
                    inability to pay debts as they fall due; or (vi) breach of
                    any of the provisions set forth in Section 13.4 and Section
                    13.7.

           11.3.2   If Reseller has not cured a breach of any of the following
                    within two (2) days of receipt of written notice from T-NET:
                    (i) non-payment of amounts due to T-NET; (ii) provide any
                    required security deposit amounts; or (iii) provide any
                    required financial reports.

                    following shall occur: (i) Reseller shall pay T-NET for all
                    Services through the date of discontinuance of Service; (ii)
                    Reseller shall pay T-NET a discontinuance charge (as an
                    early discontinuance fee and not as a penalty) equal to the
                    sum of the minimum monthly payment obligations for each of
                    the remaining months in the Term; and (iii) Reseller agrees
                    that T-NET has the right to contact the End Users and advise
                    such End Users that Reseller is in default of its Agreement
                    with T-NET, the underlying service provider, and that the
                    Service to Reseller has been interrupted. In addition,
                    Reseller agrees that T-NET has the right to market its
                    services directly or indirectly to Reseller's End Users for
                    the purpose of converting these End Users to T-NET.

12.  INDEMNIFICATION, LIABILITIES AND WARRANTY.
     -----------------------------------------

     12.1  Reseller shall defend, indemnify and hold T-NET harmless from and
           against all claims, demands, actions, causes of action, judgments,
           costs and reasonable attorneys' fees and expenses of any kind or
           nature for any and all damages of any kind arising from or related
           to any resale or use of the Services or otherwise arising under this
           Agreement including, but not limited to, any disputed PIC selections
           involving Services to be provided to Reseller for which Reseller
           cannot produce a valid LOA relevant to an ANI and PIC charge in
           question, or when T-NET is not reasonably satisfied that the validity
           of a disputed LOA has been resolved, or any dispute asserted by any
           End User Subscriber of the Services, or any violation of any FCC
           rules and regulations or other applicable laws or regulations
           pertaining to the resale or delivery of the Service to End User
           Subscribers.

          portion of the Services affected during which the Services or any part
          thereof were unavailable to Reseller. T-NET's obligations to Reseller
          with respect to a particular interruption start upon T-NET's receipt
          of Reseller's notification of the interruption and end upon service
          restoration.

          T-NET's maximum liability for any damages arising out of or under this
          Agreement shall not exceed the total charges for the Services provided
          under this Agreement during the month in which such liability arises.

     12.4 T-NET and Reseller expressly agree that this Agreement shall not give
          rise to any third party being a third-party beneficiary or being

          the Services by any third party. Reseller shall defend, indemnify and
          hold T-NET harmless from and against all claims, demands, actions,
          causes of action, judgments, costs and reasonable attorneys' fees and
          expenses of any kind or nature for any and all damages of any kind
          arising from or related to any fraudulent calls of any nature which
          may comprise a portion of the Service to the extent that the party
          claiming the call(s) in question to be fraudulent is (or had been at
          the time of the call) an End User of the Service through Reseller or
          an end user of the Service through Reseller's distribution channels.
          In the event T-NET discovers fraudulent calls being made (or
          reasonably believes fraudulent calls are being made, including but not
          limited to an End User's Usage Limit, as defined below, being
          exceeded), T-NET may (but in no circumstances is obligated to) take
          immediate action (without notice to Reseller) that is reasonably
          necessary to prevent such calls from taking place, including without
          limitation, denying Service to a particular ANI or terminating Service
          to or from specific locations or with respect to a specific calling
          card. If T-NET is providing calling card service, Reseller shall
          specify to T-NET with respect to each End User a daily and monthly
          usage limit which shall apply to each calling card issued to such End
          User ("USAGE LIMIT"). In calculating whether Usage Limit has been
          exceeded, T-NET shall use domestic calling card rate provided by
          Reseller and international calling card rates estimated by T-NET. If
          no domestic rate or Usage Limit are specified by Reseller for a
          particular End User, a Usage Limit set by T-NET based on estimated
          domestic and international rates shall apply. Reseller shall not be
          excused from paying T-NET for the Services provided to Reseller or any
          portion thereof on the basis that fraudulent calls, or calls in excess
          of a Usage Limit, comprised any portion of the Service.

     12.6 T-NET warrants that it shall provide the Services as set forth in this
          Agreement. T-NET DISCLAIMS ALL OTHER WARRANTIES EITHER EXPRESS OR
          IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OF
          MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

13.  ADDITIONAL TERMS.
     ---------------- 

     13.1 Reseller may not assign or transfer this Agreement or any rights or
          obligations without the prior written consent of T-NET. An assignment
          shall be deemed to include any change of control of Reseller.

     13.2 This Agreement is governed by and subject to the laws and the 
          jurisdiction of the courts of the Commonwealth of Virginia.

     13.3 In the event an action is brought by T-NET against Reseller to enforce
          this Agreement, in addition to any other remedy available to T-NET,
          Reseller shall reimburse T-NET for reasonable attorneys' fees and
          expenses of any kind or nature incurred in connection therewith.

     13.4 Reseller shall not disclose the terms of this Agreement to any third 
          party.

     13.5 T-NET shall not be liable for, and is excused from, any failure or
          delay in performance that is due to acts of God, acts of civil or
          military authority, acts of the public enemy, war or threats of war,
          accidents, fires, explosions, earthquakes, floods, unusually severe
          weather, epidemics, or due to any other cause beyond its reasonable
          control.

     13.6 Any notices and similar communications concerning this Agreement
          ("Notice") shall be in writing, and shall be either (i) delivered in
          person, or (ii) sent to the other party by certified mail with return
          receipt requested or by facsimile, electronically confirmed and
          followed up immediately by regular mail. Notices shall be delivered or
          sent to the parties' respective addresses or to such other address as
          either party may hereafter establish by notice given in the

                                  AGREEMENTS

     manner prescribed in this paragraph. A Notice shall be considered given
     when delivered in the manner prescribed in this paragraph.

13.7  Neither party shall issue a news release, public announcement,
      advertisement, or other form of publicity concerning the existence or the
      terms of this Agreement without obtaining prior written approval from the
      other party. Reseller shall not use T-NET's or CWI's names, logos,
      trademarks, service marks or any variations thereof in any of its
      promotional, advertising or other materials. Reseller shall not represent
      to End Users or prospective End Users that such End Users would be CWI's
      or T-NET's customers or that they may obtain CWI or T-NET services from
      Reseller. Notwithstanding the above, Reseller may, however, include the
      following statement in an item of its promotional or other material
      provided that CWI has given its prior written approval to do so:
      "[Reseller's company name]'s service may utilize the Cable & Wireless,
      Inc. network".

13.8  T-NET and Reseller are independent contracting parties. This Agreement
      shall not constitute the parties as principal and agent, partners, joint
      ventures, or employer and employee. In no way shall this Agreement or the
      provision of the Services by T-NET to Reseller hereunder be considered as
      T-NET's endorsement of Reseller or that Reseller is in any way acting as
      an authorized agent of or otherwise for T-NET.

13.9  Nothing in this Agreement shall limit T-NET's or CWI's ability to enter
      into any arrangements of any kind with any other entities with respect to
      the resale of its services or to market any of its services to any entity.

13.10 T-NET shall have no obligation to provide any support to Reseller in the
      marketing and reselling of the Services to End Users, including, but not
      limited to, making joint sales presentations or sales calls to End Users.

13.11 Reseller shall not use the Services in conjunction with the provision of
      communications services to any detention facility, including, but not
      limited to, any local, state or federal prisons.

13.12 This is a carrier-to-carrier agreement subject to (S)211 of the
      Communications Act of 1934, as amended. The Reseller is responsible for,
      and shall comply with, any and all legal and regulatory requirements with
      respect to the Reseller's resale of the Services, including those of the
      FCC and state public utility commissions. The Services are governed by
      this Agreement and all Reseller obligations and CWI rights as set forth in
      the "General Rules and Regulations" section of CWI's interstate tariff, as
      may be amended by CWI in accordance with applicable laws and regulations.
      For the purpose of this provision, the "rights" of CWI shall also include
      T-NET.

13.13 T-NET's failure to insist upon strict performance of the terms of this
      Agreement or to exercise any rights or remedies hereunder shall not waive
      any of T-NET's rights to require strict performance of such terms, to
      assert any of the same rights, or to rely on any such terms any time
      thereafter.

13.14 In the event that one or more of the provisions herein shall for any
      reason be held to be illegal or unenforceable, this Agreement shall be
      revised only to the extent necessary to make such provision(s) legal and
      enforceable; provided, however, that this Agreement as revised is
      consistent with the parties' original intent.

13.15 No Reseller purchase order or similar document shall vary or add to the 
      terms of this Agreement.

13.16 The Agreement, these General Terms and Conditions Attachment to the
      Reseller Agreement, and the terms of any documents attached hereto or
      referenced herein constitute the entire understanding of the parties with
      respect to the subject matter hereof, and they supersede all prior or
      contemporaneous oral or written agreements, understandings and
      representations.

13.17 The term "T-NET" as used in the Agreement shall mean the Total Network
      Services division of CWI, any other division or part of CWI, and CWI in
      its entirety.

                              SUBLEASE AGREEMENT

             THIS SUBLEASE AGREEMENT (this "Sublease"), made as of the 1st day

of January, 1995, by and between ITC Holding Company, Inc., a Delaware

corporation with its principal address at 1239 O.G. Skinner Drive, West Point,

Georgia, or its assignee ("Landlord"), as landlord, and ITC Transmission

Systems, Inc., a Delaware corporation ("Tenant"), as tenant.


                                  WITNESSETH:
                                  ----------

       1.    PREMISES.  Landlord is leasing an office building located at 210 
             --------
West Ninth Street, West Point, Georgia (the "Premises") pursuant to that certain
Lease Agreement dated as of July 1, 1996 by and between J. Smith Lanier & Co., 
as lessor and Landlord as lessee, and terminating on July 1, 2005 (the "Prime 
Lease"). Subject to the terms, covenants, provisions and conditions set forth 
herein, and subject further to all the terms, covenants, provisions and 
conditions contained in the Prime Lease (as such may from time to time be 
amended), Landlord hereby subleases to Tenant, and Tenant subleases from 
Landlord, the Premises.

       2.    TERM OF SUBLEASE AND TERMINATION.  The term of this Sublease (the 
             --------------------------------
"Lease Term") shall commence on January 1, 1995 and shall terminate on July 1, 
2005 or such earlier or later date as the Prime Lease shall terminate. 
Notwithstanding the foregoing, either Landlord or Tenant may terminate this 
Sublease for any reason on ninety (90) days' written notice, which notice may be
waived. At the end of the Lease Term, tenant agrees to surrender the Premises in
good repair and good working order, all of which Premises are as of the date 
hereof in such condition and good repair. Upon termination of this Sublease by 
Landlord pursuant to this Section 2, Landlord may proceed to recover possession 
of the Premises under and by virtue of the provisions of the laws of the State 
of Georgia, or by such other proceedings, including re-entry and re-possession, 
as may be applicable.

       3.    RENT.
             ----

             (a)  Payment. Tenant shall pay to Landlord during the Lease Term 
                  -------
$2,483.75 (Two Thousand Four Hundred Eighty-Three Dollars and Seventy-Five 
Cents) (the "Rent") per month in advance on the first day of every calendar 
month during the remainder of the term. Landlord shall refund to Tenant a 
prorated portion of the last monthly installment paid by Tenant, for the number 
of days in the last month of the Lease Term during which Tenant did not actually
occupy the Premises. It is agreed that payment of Rent shall cease if the 
Premises are destroyed by fire, or be so damaged by fire or any unavoidable 
casualty as to make the Premises uninhabitable, and either party may forthwith 
terminate this Sublease by written notice to that effect.

             (b)  Nonpayment; Reentry of Premises. If any installment of Rent is
                  -------------------------------
not paid within ten (10) days after the same becomes due and payable as provided
herein, although no demand shall have been made for the same, Landlord may 
terminate this Sublease forthwith and Landlord may proceed to recover possession
of the Premises under and by virtue of the provisions of the laws of the State 
of Georgia, or by such other proceedings, including re-enty and re-possession, 
as may be applicable.

       4.    TAXES, INSURANCE, UTILITIES.
             ---------------------------

             (a)  Taxes.  Tenant shall pay all taxes relating to the Premises, 
                  -----
which shall include all real estate taxes and personal property taxes and other 
assessments and governmental charges, whether federal, state, county or 
municipal, and whether they be by tax districts or authorities presently taxing 
the 

<PAGE>
 
Premises or by others subsequently created, and any other taxes and assessments 
attributable to the Premises or its operation whether or not directly paid by 
Landlord, excluding, however, federal and state taxes on income.  It is agreed 
that Tenant will be solely responsible for ad valorem taxes on its personal 
property and on the value of leasehold improvements to the extent that the same 
exceed standard building allowances.

         (b)  Insurance. Tenant agrees to carry, at Tenant's own cost and
              --------- 
expense and keep in full force and effect throughout the Lease Term (i) fire and
extended coverage insurance insuring the leasehold improvements and Tenants
furniture, fixtures, equipment and supplies and (ii) public liability insurance
in such amounts as shall be acceptable to Landlord with respect to any one
person, any one accident and property damage. All such policies shall be issued
by insurance companies licensed to do business in the State of Georgia, shall
name Landlord and Tenant as parties insured and shall contain a provision that
the same may not be canceled without giving Landlord at least thirty (30) days'
prior written notice.

         (c)  Utilities. Tenant shall pay all charges for gas, electricity and
              ---------
water used on the Premises when the bills therefor become due and payable.

     5.  GENERAL PROVISIONS.  It is agreed that all right, remedies and 
         ------------------
liabilities herein given to or imposed upon either of the parties hereto, shall 
extend to their respective heirs, executors, administrators, successors, and 
permitted assigns.  This Sublease contains the entire agreement between the 
parties and all prior negotiations and agreements are merged herein.  Any party 
may act under this Lease by its attorney or agent appointed by an instrument 
executed by such party.  Wherever a requirement is imposed on any party hereto, 
it shall be deemed that such party shall be required to perform such requirement
at its sole cost and expense unless it is specifically otherwise provided 
herein.  This Sublease may be executed in several counterparts and the 
counterparts shall constitute but one and  the same instrument.
