                               PROSPECTUS SUMMARY

     This summary highlights the material information about our company and this
exchange offer. This summary does not contain all of the information that may be
important to you in deciding whether to participate in the exchange offer. We
encourage you to read this prospectus in its entirety.

                         SUMMARY OF THE EXCHANGE OFFER

The Initial Offering of
Outstanding Notes.............   We sold the outstanding notes on February 4,
                                 2000 to Deutsche Bank Securities Inc. and Banc
                                 of America Securities LLC. We collectively
                                 refer to these parties in this prospectus as
                                 the "initial purchasers." The initial
                                 purchasers subsequently resold the outstanding
                                 notes to qualified institutional buyers under
                                 Rule 144A under the Securities Act.


Registration Rights
Agreement.....................   Simultaneously with the initial sale of the
                                 outstanding notes, we entered into a
                                 registration rights agreement for the exchange
                                 offer. In the registration rights agreement, we
                                 agreed, among other things, to use our
                                 reasonable best efforts to file a registration
                                 statement with the SEC within 120 days of
                                 issuing the outstanding notes and to cause this
                                 registration statement to be declared effective
                                 by the SEC within 210 days of issuing the
                                 outstanding notes. Because this registration
                                 statement was not declared effective by the SEC
                                 by September 6, 2000, which was the 210th day
                                 following the issuance of the outstanding
                                 notes, we have begun to incur additional
                                 interest on the outstanding notes, as
                                 liquidated damages, at a rate of 0.5% per
                                 annum. The exchange offer is intended to
                                 satisfy our obligations under the registration
                                 rights agreement. After the exchange offer is
                                 complete, you may no longer be entitled to any
                                 exchange or registration rights with respect to
                                 your outstanding notes.


The Exchange Offer............   We are offering to exchange the exchange notes,
                                 which have been registered under the Securities
                                 Act for your outstanding notes, which were
                                 issued on February 4, 2000 in the initial
                                 offering. In order to be exchanged, an
                                 outstanding note must be properly tendered and
                                 accepted. All outstanding notes that are
                                 validly tendered and not validly withdrawn will
                                 be exchanged. We will issue exchange notes
                                 promptly after the expiration of the exchange
                                 offer.

Resales.......................   We believe that the exchange notes issued in
                                 the exchange offer may be offered for resale,
                                 resold and otherwise transferred by you without
                                 compliance with the registration and prospectus
                                 delivery provisions of the Securities Act,
                                 provided that:

                                 - the exchange notes are being acquired in the
                                   ordinary course of your business;

                                 - you are not participating, do not intend to

                                   issued to you in the exchange offer; and

                                 If any of these conditions are not satisfied
                                 and you transfer any exchange notes issued to
                                 you in the exchange offer without delivering a
                                 prospectus meeting the requirements of the
                                 Securities Act or without an exemption from
                                 registration of your exchange notes from these
                                 requirements, you may incur liability under the
                                 Securities Act. We will not assume, nor will we
                                 indemnify you against, these liabilities.

                                 notes in the exchange offer for its own account
                                 in exchange for outstanding notes that were
                                 acquired by that broker-dealer as a result of
                                 market-making or other trading activities, must
                                 acknowledge that it will deliver a prospectus
                                 meeting the requirements of the Securities Act
                                 in connection with any resale of the exchange
                                 notes. A broker-dealer may use this prospectus
                                 for an offer to resell, resale or other
                                 retransfer of the exchange notes issued to it
                                 in the exchange offer.

                                 of outstanding notes on September 14, 2000.

                                 New York City time, October 16, 2000, unless we
                                 decide to extend the expiration date. We will

                                 20 business days, or longer if required by

                                 the outstanding notes.


Conditions to the Exchange
Offer.........................   The exchange offer is not subject to any
                                 material condition other than that the exchange
                                 offer not violate applicable law or any
                                 applicable interpretation of the Staff of the
                                 SEC.

Procedures for Tendering
Outstanding Notes.............   We issued the outstanding notes as global
                                 securities. When the outstanding notes were
                                 issued, we deposited the global notes
                                 representing the outstanding notes with United
                                 States Trust Company of New York, as book-entry
                                 depositary. United States Trust Company issued
                                 a certificateless depositary interest in each
                                 global note we deposited with it, which
                                 represents a 100% interest in the notes, to The
                                 Depositary Trust Company, known as DTC.
                                 Beneficial interests in the outstanding notes,
                                 which are held by direct or indirect
                                 participants in DTC through the certificateless
                                 depositary interest, are shown on records
                                 maintained in book-entry form by DTC.

                                 You may tender your outstanding notes through
                                 book-entry transfer in accordance with DTC's
                                 Automated Tender Offer Program, known as ATOP.
                                 To tender your outstanding notes by a means
                                 other than book-entry transfer, a letter of
                                 transmittal must be completed and signed
                                 according to the instructions contained in the
                                 letter. The letter of transmittal and any other
                                 documents required by the letter of transmittal
                                 must be delivered to the exchange agent by
                                 mail, facsimile, hand delivery or overnight
                                 carrier. In addition, you must deliver the
                                 outstanding

                                 notes to the exchange agent or comply with the
                                 procedures for guaranteed delivery. See "The
                                 Exchange Offer -- Procedures for Tendering
                                 Outstanding Notes" for more information.

                                 Do not send letters of transmittal and
                                 certificates representing outstanding notes to
                                 us. Send these documents only to the exchange
                                 agent. See "The Exchange Offer -- Exchange
                                 Agent" for more information.

Special Procedures for
Beneficial Owners.............   If you are the beneficial owner of book-entry
                                 interests and your name does not appear on a
                                 security position listing of DTC as the holder
                                 of the book-entry interests or if you are a
                                 beneficial owner of outstanding notes that are
                                 registered in the name of a broker, dealer,
                                 commercial bank, trust company or other nominee
                                 and you wish to tender the book-entry interest
                                 or outstanding notes in the exchange offer, you
                                 should contact the person in whose name your
                                 book-entry interests or outstanding notes are
                                 registered promptly and instruct that person to
                                 tender on your behalf.


Withdrawal Rights.............   You may withdraw the tender of your outstanding
                                 notes at any time prior to 5:00 p.m., New York
                                 City time on October 16, 2000.


Federal Income Tax
Considerations................   Based upon advice of counsel, we believe that
                                 the exchange of outstanding notes will not be a
                                 taxable event for United States federal income
                                 tax purposes. See "United States Federal Income
                                 Tax Consequences" for a more detailed
                                 discussion of the U.S. federal income tax
                                 consequences of the exchange offer and the
                                 ownership and disposition of the exchange
                                 notes.

Use of Proceeds...............   We will not receive any proceeds from the
                                 issuance of exchange notes in the exchange
                                 offer. We will pay all of our expenses incident
                                 to the exchange offer.

Exchange Agent................   United States Trust Company of New York is
                                 serving as the exchange agent in connection
                                 with the exchange offer.

                     SUMMARY OF TERMS OF THE EXCHANGE NOTES

     The form and terms of the exchange notes are the same as the form and terms
of the outstanding notes, except that the exchange notes will be registered
under the Securities Act. As a result, the exchange notes will not bear legends
restricting their transfer and will not contain the registration rights and
liquidated damage provisions contained in the outstanding notes. The exchange
notes represent the same debt as the outstanding notes. Both the outstanding
notes and the exchange notes are governed by the same indenture. We use the term
notes in this prospectus to collectively refer to the outstanding notes and the
exchange notes.

Issuers....................  The exchange notes will be joint and several
                             obligations of NATG and Orius Capital. Orius
                             Capital is a wholly owned subsidiary of NATG, which
                             in turn is a wholly owned subsidiary of Parent.
                             Orius Capital was formed in connection with the
                             offering of the outstanding notes. Orius Capital
                             has no assets, no liabilities other than the
                             outstanding notes and no operations, and is
                             prohibited from engaging in any business activities
                             other than in connection with the notes.

Securities Offered.........  $150,000,000 in principal amount of 12 3/4% senior
                             subordinated notes due 2010, Series B.

Maturity...................  February 1, 2010.

Interest Rate..............  12 3/4% per year, calculated using a 360-day year.

Interest Payment Dates.....  February 1 and August 1, commencing August 1, 2000.

Ranking....................  The exchange notes will be unsecured senior
                             subordinated obligations of the issuers and will
                             rank (1) junior to their existing and future senior
                             debt, (2) senior to all debt of the issuers that is
                             expressly subordinated to the exchange notes and
                             (3) equal to all other debt and other obligations
                             of the issuers. As of June 30, 2000, the issuers
                             had approximately $290.3 million of senior debt
                             (including equipment debt and leases of $4.7
                             million), in addition to approximately $43.0
                             million that they had available to borrow under the
                             senior credit facilities.

Guarantees.................  The issuers' obligations under the exchange notes
                             and the related indenture will be jointly,
                             severally, fully and unconditionally guaranteed on
                             an unsecured senior subordinated basis by Parent
                             and by all of the issuers' existing and future
                             domestic subsidiaries. We collectively refer to
                             these subsidiaries in this prospectus as the
                             guarantors. See "Description of the
                             Notes -- Guarantees." As of June 30, 2000, the
                             guarantors had approximately $290.3 million of
                             senior debt to which their guarantees of the
                             outstanding notes were subordinated.

Optional Redemption........  Except as described in the next paragraph, the
                             issuers cannot redeem the exchange notes until
                             February 1, 2005. Thereafter, they may redeem some
                             or all of the notes at the redemption prices listed
                             in the "Description of the Notes" section under the
                             heading "Optional Redemption."

                             At any time before February 1, 2003, the issuers
                             can choose to redeem up to 35% of the notes issued
                             under the indenture with money raised in one or
                             more equity offerings, as long as:

                             - they pay 112.75% of the principal amount of the
                               notes, plus accrued interest;

                                        4
<PAGE>   9

                             - they give notice of redemption within 60 days of
                               completing the equity offering; and

                             - at least 65% of the aggregate principal amount of
                               notes issued under the indenture remains
                               outstanding afterwards.

Change of Control Offer....  If a change of control occurs, the issuers must
                             offer to purchase exchange notes from holders at
                             101% of their principal amount, plus accrued
                             interest.

                             The issuers might not be able to pay you the
                             required price for exchange notes you present at
                             the time of a change of control, because:

                             - they might not have enough funds at that time; or

                             - the terms of their senior debt may prevent them
                               from paying that amount.

Asset Sale Proceeds........  If we engage in asset sales, we generally must
                             either (1) invest the net cash proceeds from the
                             sales in our business, (2) prepay senior debt
                             within a period of time or (3) make an offer to
                             purchase a principal amount of exchange notes equal
                             to the excess net cash proceeds from the asset
                             sale. The purchase price of the exchange notes out
                             of the asset sale proceeds will be 100% of their
                             principal amount, plus accrued interest.

Certain Covenants..........  The indenture under which the outstanding notes
                             were issued will govern the exchange notes. This
                             indenture contains covenants limiting our ability
                             to, among other things:

                             - incur additional debt;

                             - pay dividends or distributions on our capital
                               stock or repurchase our capital stock;

                             - issue stock of subsidiaries;

                             - make certain investments;

                             - create liens on our assets to secure debt;

                             - enter into transactions with affiliates;

                             - merge or consolidate with another company; and

                             - transfer and sell assets.

                             important limitations and exceptions.

                                  ORIUS CORP.

     Unless otherwise indicated, pro forma revenue data presented in this
prospectus for 1999 and for the six months ended June 30, 2000 give effect to
(1) our acquisition of LISN Holdings, Inc. and its subsidiaries in December
1999, and (2) the nine other acquisitions we have completed in 1999 and 2000.

     We believe that we are one of the largest independent providers of
comprehensive telecom infrastructure services in the U.S., with operations in 48
states. We offer a full spectrum of services, including:

     - External Telecom Services -- installation, design, engineering and
       maintenance of fiber optic, coaxial and copper cable networks for the
       telecom industry, which consists of the telecommunications services
       segment and the broadband services segment; and

     - Internal Telecom Services -- engineering, furnishing and installation of
       network equipment and related components and related maintenance
       services, primarily in the central offices of telecommunications services
       providers, which we refer to as "EF&I Services," and similar network
       services for commercial, governmental and institutional entities, which
       we refer to as "Network Services."

We believe that our ability to provide comprehensive, quality service on a
nationwide basis positions us as a leading, full-service provider of telecom
infrastructure services.

     Our principal customers are providers of telecom services, including
telecommunications services and broadband services. Providers of
telecommunications services generally include the Regional Bell Operating
Companies and other incumbent local exchange carriers, competitive local
exchange carriers and long distance carriers. Our primary telecommunications
services customers include Ameritech, AT&T, DTI, GTE, MCI WorldCom, Verizon and
Williams Communications. Broadband services refer to the emerging initiative of
traditional cable companies to provide a comprehensive package of cable service,
telephone service, Internet access and other data and voice transmission
services. Our primary broadband services customers include Adelphia, AT&T
Broadband & Internet Services, Charter Communications, Clearsource, Comcast, Cox
Communications, Digital Access and Universal Access. In addition, we provide our
Network Services for commercial, governmental and institutional customers such
as Compaq, Dell, EDS and the World Bank.

                             COMPETITIVE STRENGTHS

     We believe that we possess a number of competitive strengths that position
us as a leading provider of telecom infrastructure services and provide us with
the ability to meet the increased demand for these services and to take
advantage of the strong technology-driven growth occurring in the telecom
industry, including:

     - Comprehensive service capabilities,

     - Broad geographic coverage,

     - Strong customer relationships,

     - Reputation and commitment to quality,

     - Decentralized operating strategy, and

     - Experienced management.

                               BUSINESS STRATEGY

     Our objective is to enhance what we believe is our position as one of the
largest providers of comprehensive telecom infrastructure services in the U.S.
We seek to utilize our competitive strengths to take advantage of substantial
growth opportunities in the telecom industry that favor large companies like us
with significant capital resources. Key elements of our growth and operating
strategies include the following:

     - Continuing to Grow Internally. We believe we can continue to achieve
       internal growth by:

               - Continuing to develop national service capabilities;

               - Focusing on cross-selling opportunities;

               - Maximizing performance of existing operations; and

               - Expanding our service offerings.

     - Selectively Pursuing Strategic Acquisitions.

     - Attracting, Training and Retaining Highly Qualified Personnel.

                                LISN ACQUISITION

     On December 15, 1999, Parent and LISN Holdings, Inc. entered into a series
of transactions that resulted in LISN becoming a wholly owned subsidiary of
NATG. In connection with the LISN acquisition, Parent was acquired by an
investor group consisting of LISN's former stockholders, including Willis Stein
& Partners and members of LISN's management, certain new co-investors and
members of Parent's and its subsidiaries' management. Willis Stein & Partners,
its co-investors and members of LISN's management invested cash in the aggregate
of $112.2 million in LISN and exchanged their LISN securities for similar
securities issued by Parent as part of the LISN acquisition. For a more detailed
description of the components of the LISN acquisition, see "LISN Acquisition."

                              RECENT DEVELOPMENTS

     Since January of this year we have completed four acquisitions. In January
2000, we completed the acquisition of Irwin Utilities of Texas, Inc. and three
related entities. Irwin is a Dallas, Texas based provider of External Telecom
Services to telecom services providers in a variety of states. Irwin's primary
customers include AT&T Broadband & Internet Services, Charter Communications and
Time Warner. In April 2000, we completed the acquisitions of Fenix
Communications, Inc. and Fenix Limited Partnership, which we collectively refer
to as "Fenix," and Midwest Splicing and Activation, Inc. Fenix and Midwest
provide External Telecom Services to broadband service providers in and around
the Great Lakes region of the U.S. and the Midwest region of the U.S.,
respectively. Fenix's primary customer is Charter Communications and Midwest's
primary customers include Media One and Paragon Cable. In May 2000, we completed
the acquisition of Hattech, Inc. Based in Chantilly, Virginia, Hattech provides
a wide range of network integration services to telecommunications service
providers and internet service providers. Hattech's primary customer is AT&T.

     The aggregate purchase price for these acquisitions was approximately $74.2
million, consisting of approximately $60.7 million of cash, $12.2 million of
Parent's securities and the assumption of $1.3 million of debt. We funded $42.0
million of the cash purchase price with borrowings under our senior credit
facilities. These four companies had aggregate revenue and EBITDA for the year
ended December 31, 1999 of $78.8 million and $15.8 million, respectively. Our
revenue and cash flow provided by operations were $167.0 million and $13.8
million, respectively, for the year ended December 31, 1999.

     In July 1999, we entered into a non-binding letter of intent to acquire a
northeastern EF&I service provider for approximately $20.0 million. Completion
of this acquisition is conditioned upon satisfactory

                                        7

completion of due diligence and negotiation of a definitive agreement. If we
complete this acquisition, we would expect the closing to occur in the fourth
quarter.

                                  RISK FACTORS

     You should carefully consider the following factors and the other
information in this prospectus before you decide whether to participate in the
exchange offer.

RISKS ASSOCIATED WITH THE EXCHANGE OFFER

BECAUSE THERE IS NO PUBLIC MARKET FOR THE NOTES, YOU MAY NOT BE ABLE TO RESELL
YOUR NOTES.

     The exchange notes will be registered under the Securities Act, but will
constitute a new issue of securities with no established trading market.
Therefore, you may not be able to sell your notes. Even if a trading market were
to develop, the market could be illiquid. If the trading market for the notes is
illiquid, you may not be able to sell your notes or may not be able to sell them
at a desirable price.

     If a trading market were to develop, the exchange notes might trade at
higher or lower prices than their principal amount or purchase price, depending
on many factors, including prevailing interest rates, the market for similar
debentures and our financial performance.

     We do not intend to list the notes on any trading exchange or to do
anything to facilitate the develop of a trading market for the notes. We
understand that the initial purchasers presently intend to make a market in the
notes. However, they are not obligated to do so, and any market-making activity
with respect to the notes may be discontinued at any time without notice. In
addition, any market-making activity will be subject to the limits imposed by
the Securities Act and the Securities Exchange Act, and may be limited during
the exchange offer or the pendency of an applicable shelf registration
statement.

     In addition, any outstanding note holder who tenders in the exchange offer
for the purpose of participating in a distribution of the exchange notes may be
deemed to have received restricted securities, and if so, will be required to
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. For a description of
these requirements, see "Exchange Offer; Registration Rights."


YOUR OUTSTANDING NOTES WILL NOT BE ACCEPTED FOR EXCHANGE IF YOU FAIL TO FOLLOW
THE EXCHANGE OFFER PROCEDURES AND, AS A RESULT, YOUR NOTES WILL CONTINUE TO BE
SUBJECT TO EXISTING TRANSFER RESTRICTIONS AND YOU MAY NOT BE ABLE TO SELL YOUR
OUTSTANDING NOTES.


     We will not accept your notes for exchange if you do not follow the
exchange offer procedures. We will issue exchange notes as part of this exchange
offer only after a timely receipt of your outstanding notes, a properly
completed and duly executed letter of transmittal and all other required
documents. Therefore, if you want to tender your outstanding notes, please allow
sufficient time to ensure timely delivery. If we do not receive your notes,
letter of transmittal and other required documents by the expiration date of the
exchange offer, we will not accept your notes for exchange. We are under no duty
to give notification of defects or irregularities with respect to the tenders of
outstanding notes for exchange. If there are defects or irregularities with
respect to your tender of notes, we will not accept your notes for exchange.

IF YOU DO NOT EXCHANGE YOUR OUTSTANDING NOTES, YOUR OUTSTANDING NOTES WILL
CONTINUE TO BE SUBJECT TO THE EXISTING TRANSFER RESTRICTIONS AND YOU MAY NOT BE
ABLE TO SELL YOUR OUTSTANDING NOTES.

     We did not register the outstanding notes, nor do we intend to do so
following the exchange offer. Outstanding notes that are not tendered will
therefore continue to be subject to the existing transfer restrictions and may
be transferred only in limited circumstances under the securities laws. If you
do not exchange your outstanding notes, you will lose your right to have your
outstanding notes registered under the federal securities laws. As a result, if
you hold outstanding notes after the exchange offer, you may not be able to sell
your outstanding notes.

                                       10
<PAGE>   15

RISKS RELATING TO THE NOTES

BECAUSE WE HAVE SUBSTANTIAL DEBT, WE MAY HAVE DIFFICULTY IN MAKING PAYMENTS ON
THE NOTES.

     We have indebtedness that is substantial in relation to our shareholders'
equity. Because we have substantial debt, we may have difficulty in making
payments on the notes. As of June 30, 2000, we had $591.0 million in aggregate
principal amount of consolidated indebtedness outstanding, $290.3 million of
which was senior to the notes, and a shareholders' deficit of $215.6 million.

     Our substantial indebtedness could have important consequences for you,
including:

     - we may have difficulty making payments on the notes;

     - our ability to obtain additional financing for working capital, capital
       expenditures, acquisitions or general corporate purposes may be impaired;

     - a substantial portion of our cash flow from operations must be dedicated
       to the payment of principal and interest on our debt, reducing the funds
       available to us for other purposes, including expansion through
       acquisitions and expansion of our service offerings;

     - certain of our borrowings are and will continue to be at variable rates
       of interest, which exposes us to the risk of a rise in interest rates;

     - substantially all of our assets have been pledged to secure our
       obligations under our senior credit facilities and will be unavailable to
       secure other debt, which will limit our ability to obtain additional debt
       financing;

     - we may be substantially more leveraged than some of our competitors,
       which may place us at a competitive disadvantage; and

     - our substantial indebtedness may hinder our ability to adjust rapidly to
       changing market conditions and could make us more vulnerable in the event
       of a downturn in general economic conditions or our business.

     Our ability to make scheduled payments or to refinance our obligations
under our indebtedness will depend on our financial and operating performance,
which, in turn, is subject to prevailing economic conditions and to financial,
business and other factors beyond our control. Our operating performance, cash
flow and capital resources may not be sufficient for payment of our debt in the
future. If our cash flow and capital resources are not sufficient to fund our
debt service obligations, we could be forced to reduce or delay scheduled
expansion and capital expenditures, sell material assets or operations, obtain
additional capital or restructure our debt. In the event that we are required to
dispose of material assets or operations or restructure our debt to meet our
debt service and other obligations, we may not be able to do so on favorable
terms and may not be able to do so quickly enough to allow us to make payments
on the notes when due. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

DESPITE SUBSTANTIAL LEVELS OF DEBT, WE MAY STILL BE ABLE TO INCUR EVEN MORE
DEBT, WHICH COULD FURTHER EXACERBATE THE RISK THAT WE MAY NOT BE ABLE TO MAKE
PAYMENTS ON THE NOTES.


     We may be able to incur substantial debt in the future. The terms of the
indenture and the senior credit facilities permit the incurrence of additional
debt under some circumstances. In particular, as of July 5, 2000, we would have
been able to incur an additional $100.0 million of borrowings. We anticipate
that we will fund future acquisitions in part through the incurrence of
additional indebtedness. For example, if we consummated the acquisition
contemplated by the July 1999 non-binding letter of intent disclosed under
"Prospectus Summary -- Recent Developments," we expect that we would fund a
portion of the $20 million purchase price with borrowings under our senior
credit facility. If new debt is added to our existing debt, the related risks
that you face as a holder of the notes could intensify.


                                       11
<PAGE>   16

BECAUSE THE NOTES AND THE GUARANTEES ARE SUBORDINATED TO SENIOR DEBT, IN THE
EVENT THE ISSUERS BECOME INSOLVENT, THE HOLDERS OF THE NOTES WILL NOT RECEIVE
ANY PAYMENT ON THE NOTES UNTIL ALL SENIOR DEBT IS PAID IN FULL.

     Payment on the notes is subordinated in right of payment to all of our
senior indebtedness, including the senior credit facilities. By reason of the
subordination provisions of the indenture, in the event of the insolvency,
liquidation, reorganization, dissolution or other winding-up of the issuers,
holders of notes will not receive any payment on the notes until all senior
debt, including the senior credit facilities, is paid in full. As a result, in
the event of the liquidation or dissolution of the issuers, holders of the notes
may receive less, ratably, than holders of senior debt.

     In addition, no payment will be able to be made in respect of the notes
during the continuance of payment defaults on our senior debt, and payments on
the notes may be prohibited for up to 180 consecutive days in the event of a
non-payment default on our senior debt. As of June 30, 2000, the aggregate
principal amount of our consolidated indebtedness to which the notes were
subordinated was approximately $290.3 million. The notes are unsecured, and are
effectively subordinated to all secured obligations to the extent of the value
of the assets securing the secured obligations. The guarantees are similarly
subordinated and, as of June 30, 2000, were subordinated to approximately $290.3
million of debt.


ORIUS CAPITAL HAS NO ASSETS FROM WHICH TO MAKE PAYMENTS ON THE NOTES AND
PARENT'S GUARANTEE PROVIDES LITTLE, IF ANY, ADDITIONAL CREDIT SUPPORT FOR THE
NOTES. YOU SHOULD NOT RELY ON EITHER ORIUS CAPITAL OR PARENT TO RECEIVE PAYMENTS
ON THE NOTES.


     Orius Capital was formed in connection with the initial offering of the
outstanding notes and has no assets and no operations from which to make
payments on the notes and is prohibited from engaging in any business
activities, except in connection with the notes. In addition, Parent is a
holding company whose sole source of operating income and cash flow is derived
from NATG and whose only material asset is NATG's capital stock. Parent is
therefore dependent upon dividends and distributions of NATG's earnings to
perform its obligations under its guarantee. As a result, Parent's guarantee
provides little, if any, additional credit support for the notes. Furthermore,
the indenture does not impose any restrictions on the business or operations of
Parent or on, among other things, the amount of indebtedness that Parent may
incur.

NATG WILL NOT BE ABLE TO MAKE PAYMENTS ON THE NOTES UNLESS IT RECEIVES
SUFFICIENT DIVIDENDS AND LOANS FROM ITS SUBSIDIARIES.

     NATG is a holding company. Its subsidiaries conduct substantially all of
its operations and own substantially all of its assets. NATG's cash flow and its
ability to meet its debt service obligations depend upon the cash flow of its
subsidiaries and the payment of funds by its subsidiaries in the form of loans
and dividends. NATG will not be able to make payments on the notes unless it
receives sufficient dividends and loans from its subsidiaries. NATG's
subsidiaries are not obligated to make funds available to NATG for payments on
the notes. In addition, the ability of its subsidiaries to make payments to it
will depend on their earnings, the terms of their debt, business and tax
considerations and legal restrictions.

IF WE BECAME INSOLVENT, THE LENDERS UNDER THE SENIOR CREDIT FACILITY WOULD HAVE
A CLAIM ON ALL OF OUR ASSETS BEFORE THE HOLDERS OF THE NOTES.

     The notes are not secured by any of Parent's assets or any of its
subsidiaries' assets. Our obligations under our senior credit facilities are
secured by substantially all of Parent's assets and its subsidiaries' assets. If
an issuer became insolvent or was liquidated, or if payment under the senior
credit facilities was accelerated, the lenders under the senior credit
facilities will have a claim on all assets securing the senior credit facilities
before the holders of unsecured debt, including the notes.

                                       12
<PAGE>   17

IF WE ARE UNABLE TO COMPLY WITH THE NUMEROUS COVENANTS UNDER THE SENIOR CREDIT
FACILITIES AND THE INDENTURE, ALL OF OUR INDEBTEDNESS COULD BE ACCELERATED AND
WE MIGHT NOT BE ABLE TO PAY THE NOTES IN FULL.

     In the event that we fail to comply with the numerous covenants contained
in our senior credit facilities and the indenture, we would be in default under
our senior credit facilities and the maturity of substantially all of our
long-term indebtedness could be accelerated. If the indebtedness under the
senior credit facilities was accelerated, we may not be able to repay the
indebtedness under the notes in full.

     The senior credit facilities require Parent to meet financial ratios and
tests, including:

     - a minimum consolidated net worth test;

     - a maximum consolidated total leverage test;

     - a minimum interest coverage test; and

     - a minimum consolidated fixed charge coverage test.

     Our ability to comply with the covenants and other terms of our senior
credit facilities and the indenture and to satisfy our debt obligations will
depend on our future operating performance.

     See "Description of Senior Credit Facilities" and "Description of the
Notes."

IF WE WERE REQUIRED TO WRITE OFF A SIGNIFICANT AMOUNT OF OUR GOODWILL OR TO
SIGNIFICANTLY REDUCE THE PERIOD OVER WHICH WE AMORTIZE GOODWILL, WE MIGHT NOT BE
ABLE TO COMPLY WITH THE NET WORTH COVENANT IN OUR SENIOR CREDIT FACILITY, WHICH
COULD CAUSE ALL OF OUR INDEBTEDNESS TO BE ACCELERATED, IN WHICH CASE WE MIGHT
NOT BE ABLE TO PAY THE NOTES IN FULL.

     If we were required to write off a significant amount of our goodwill or to
significantly reduce the period over which we amortize goodwill, we might not be
able to comply with the net worth covenant in our senior credit facility, which
could cause all of our indebtedness to be accelerated. If all of our
indebtedness was accelerated, we might not be able to pay the notes in full.

     We have a significant amount of goodwill. As of June 30, 2000, we had
unamortized goodwill of $418.7 million, which is currently being amortized over
a 25-year period. If we were to determine that this goodwill had become
impaired, meaning that the value of our business had declined, we would be
required to write-off a portion of this goodwill, which would reduce our
earnings and our net worth. If the write-off was significant, it could cause us
to violate our net worth covenant. We are required under our senior credit
facility to maintain net worth of at least $128.5 million. As of June 30, 2000,
we had net worth, as defined in our senior credit agreement, of $189.2 million.

     Similarly, if we were required, due to a change in accounting policy or
otherwise, to significantly reduce the period over which we amortize our
goodwill, we might violate the net worth covenant. A reduction in the
amortization period would result in an increase in our amortization expense,
which in turn would reduce our earnings and net worth. See "Description of
Senior Credit Facilities."


THE GUARANTEES MAY BE UNENFORCEABLE DUE TO FRAUDULENT CONVEYANCE STATUTES, IN
WHICH CASE YOU WOULD NOT BE ABLE TO RELY UPON THE GUARANTORS' ASSETS TO RECEIVE
PAYMENT ON THE NOTES.


     The obligations of the guarantors may be subject to challenge under state
or federal fraudulent transfer laws. If a guarantee were determined to be a
fraudulent conveyance, it could be unenforceable and you would not be able to
rely on the guarantee to secure payment of the notes. In general, under
fraudulent conveyance laws, a court can subordinate or avoid an obligation such
as a guarantee if it determines that the obligation was incurred with actual
intent to hinder, delay or defraud creditors or if the

                                       13
<PAGE>   18

guarantor did not receive fair consideration or reasonably equivalent value for
the guarantee and the guarantor also:

     - was insolvent or rendered insolvent as a result of the guarantee;

     - was engaged in a business or transaction for which the guarantor's
       remaining assets constituted unreasonably small capital; or

     - intended to incur, or believed that it would incur, debts beyond its
       ability to pay at maturity.

     Generally an entity is insolvent if:

     - the sum of its debts, including contingent or unliquidated debts, is
       greater than all of its property at a fair valuation; or

     - the present fair salable value of its assets is less than the amount
       required to pay its probable liability on existing debts as they become
       due.


WE MAY NOT BE ABLE TO REPURCHASE THE NOTES UPON A CHANGE OF CONTROL OFFER, IN
WHICH CASE WE WOULD BE IN DEFAULT ON THE NOTES. A CHANGE OF CONTROL MAY ALSO
CAUSE ALL OF OUR SENIOR DEBT TO BE ACCELERATED, IN WHICH CASE WE MAY NOT BE ABLE
TO PAY THE NOTES IN FULL.


     Upon the occurrence of specified change of control events, we are required
to offer to purchase each holder's notes at a price of 101% of their principal
amount plus accrued interest. We may not have sufficient financial resources to
purchase all of the notes that holders tender to us upon a change of control
offer. The occurrence of a change of control could also constitute an event of
default under the senior credit facilities and/or any of our future credit
agreements. Our bank lenders may also have the right to prohibit us from
repurchasing the notes, in which event we would be in default on the notes. See
"Description of the Notes -- Change of Control."

RISKS RELATING TO OUR BUSINESS

IF WE ARE UNABLE TO CONTINUE TO SUCCESSFULLY INTEGRATE THE COMPANIES WE HAVE
ACQUIRED AND TO MANAGE THE RISKS ASSOCIATED WITH OUR ACQUISITION STRATEGY,
INCLUDING THE RISKS ASSOCIATED WITH INCURRING ADDITIONAL DEBT TO FUND
ACQUISITIONS, OUR PROFITABILITY WOULD BE REDUCED AND WE MAY NOT BE ABLE TO
GENERATE ENOUGH CASH FLOW TO MAKE PAYMENTS ON THE NOTES.

     If we are unable to integrate or successfully manage the companies we have
acquired, including LISN, or the businesses that we may acquire in the future,
we may not realize anticipated cost savings and revenue growth, which may result
in reduced profitability or operating losses and prevent us from making payments
on the notes.

     Acquisitions involve a number of special risks including:

     - failure of the acquired businesses to achieve the results we expect;

     - diversion of our management's attention from operational matters;

     - our inability to retain key personnel of the acquired businesses;

     - risks associated with unanticipated events or liabilities;

     - risks associated with the incurrence of additional senior debt to fund
       the acquisitions;

     - the potential disruption of our business; and

     - customer dissatisfaction or performance problems at the acquired
       businesses.

                                       14
<PAGE>   19

     The realization of all or any of the risks described above could materially
and adversely affect the reputation of our company and reduce our revenues,
which could prevent us from making payments on the notes.

IF WE ARE UNABLE TO ATTRACT ACQUISITION CANDIDATES AND TO OBTAIN FINANCING FOR
FUTURE ACQUISITIONS, OUR BUSINESS MAY NOT BE SUCCESSFUL AND WE MAY NOT BE ABLE
TO MAKE PAYMENTS ON THE NOTES.

     We may be unable to support our strategy of growth through acquisitions if
we cannot attract acquisition candidates and finance future acquisitions. We
expect to face competition for acquisition candidates, which may limit the
number of our acquisition opportunities and may lead to higher acquisition
prices. If we are unable to grow through acquisitions, our business may not be
successful and we may not be able to make payments on the notes.

     We expect to use Parent's equity or debt securities for all or a portion of
the consideration for future acquisitions. If Parent's equity securities do not
maintain a sufficient value or potential acquisition candidates are unwilling to
accept Parent's equity or debt securities as part of the consideration for the
sale of their businesses, we may be required to utilize more of our cash
resources to pursue our acquisition program, whether through additional
borrowings under our senior credit facilities, cash on hand or otherwise. Using
cash for acquisitions limits our financial flexibility and makes us more likely
to seek additional capital through future debt or equity financings. When we
seek additional debt or equity financings, we may not be able to complete the
financing or may not be able to complete the financing on terms acceptable to
us.

     We are required to obtain the consent of our senior lenders for
acquisitions that exceed minimum levels of cash consideration and the aggregate
amount we can borrow under the senior credit facilities to finance acquisitions
is limited. Our senior lenders may not permit us to complete future
acquisitions.

WE HAVE EXPERIENCED RAPID GROWTH IN THE PAST TWO YEARS, HAVING ACQUIRED 18
BUSINESSES, AND WE INTEND TO ACQUIRE ADDITIONAL BUSINESSES IN THE FUTURE. IF WE
ARE UNABLE TO MANAGE THIS GROWTH, OUR PROFITABILITY WILL BE REDUCED AND WE MAY
NOT BE ABLE TO MAKE PAYMENTS ON THE NOTES.

     Our acquisition of 18 businesses in the past two years has placed, and is
expected to continue to place, a significant strain on our managerial,
operational and financial resources. As part of our growth strategy, we expect
to pursue additional acquisitions in the future. If we are unable to manage our
growth, our profitability will be reduced and we may not be able to make
payments on the notes. To manage any future growth, we must continue to
implement and improve our operational and financial systems, and must expand,
train and manage our expanded employee base. For example, we had 5,885 employees
at June 30, 2000, as compared to 2,670 employees at June 30, 1999. We may
encounter unexpected difficulties in managing the expansion of our operations,
and our systems, products and controls may be inadequate to support our expanded
operations. Any inability to manage growth effectively could reduce our
profitability and prevent us from making payments on the notes.

ALL OF OUR CUSTOMER CONTRACTS CAN BE CANCELED ON SHORT NOTICE. IF OUR CUSTOMER
CONTRACTS WERE CANCELED, OUR REVENUE WOULD DECREASE, WHICH COULD PREVENT US FROM
MAKING PAYMENTS ON THE NOTES.


     All of our customer contracts are cancelable upon 90 days' notice or less
without penalty, except, in some cases, for the recovery of our actual committed
costs and profit on work performed up to the date of cancellation. Accordingly,
our future revenues may not approximate our historical performance. In addition,
because all of our customer contracts are cancelable, our backlog, which was
approximately $663 million as of June 30, 2000, is not necessarily indicative of
our future revenue. If any canceled contracts are not replaced with contracts
from other customers, or if we do not receive orders under our master service
agreements, our revenue would decrease and we could be unable to meet our fixed
expenses, including payments on the notes.

IF WE WERE TO LOSE VERIZON AS A CUSTOMER, OUR REVENUE WOULD DECREASE
SUBSTANTIALLY, WHICH COULD PREVENT US FROM MAKING PAYMENTS ON THE NOTES.

     Our revenue from Verizon represented approximately 25.2% of our pro forma
revenue for the six months ended June 30. In recent months, our revenue from
Verizon has increased in both absolute terms and as a percentage of our revenue
and this trend may continue for the foreseeable future. The loss of Verizon as a
customer or a significant decline in its demand for our services would
substantially reduce our revenue and could prevent us from making payments on
the notes. Many of our contracts with Verizon do not guarantee us a particular
amount of work, therefore, despite the long-term nature of some of these
contracts, they do not provide us with the security that a typical long-term
contract might.

OUR EXTERNAL TELECOM SERVICES BUSINESS IS SEASONAL, EXPOSING US TO REDUCED
REVENUE IN THE FIRST AND FOURTH QUARTERS OF EACH YEAR, WHICH MAY NEGATIVELY
IMPACT THE TRADING MARKET FOR YOUR NOTES.

     Our revenue and net income in the first quarter and the fourth quarter have
in the past been, and may in the future be, reduced by adverse holiday season
shutdowns, weather conditions and the year-end budgetary spending patterns of
our customers. The quarterly variations in our revenues and income could
negatively impact the trading market for your notes, should a trading market
develop, in which case you may not be able to sell your notes or to sell them at
a desirable price.

     For example, our pro forma revenue for each of the four quarters of 1999
and the first and second quarters of 2000 were:

<TABLE>

                        QUARTER                           (IN MILLIONS)

<S>                                                       <C>
1999
  First quarter.........................................      $111
  Second quarter........................................       140
  Third quarter.........................................       166
  Fourth quarter........................................       170
2000
  First quarter.........................................       171
  Second quarter........................................       199
</TABLE>


As shown above, our revenues remained flat during the fourth quarter of 1999 and
the first quarter of 2000. Because our operating results may vary significantly
from quarter to quarter based on the factors described above, our operating
results may not meet the expectations of analysts and investors, and this could
negatively impact the trading market for your notes.


WE EXPECT OUR QUARTERLY RESULTS TO FLUCTUATE. IF WE FAIL TO MEET REVENUE AND
EARNINGS ESTIMATES, THE TRADING MARKET FOR YOUR NOTES WOULD BE ADVERSELY
EFFECTED.

     Quarterly variations in our revenues and net income result from several
factors, including:

     - the timing and magnitude of acquisitions;

     - variations in the margins of projects performed during any particular
       quarter;

     - the timing and volume of work under new agreements;

     - the spending patterns of customers;

     - the termination of existing agreements;

     - costs we incur to support growth internally or otherwise;

     - the change in mix of our customers, contracts and business;

                                       16
<PAGE>   21

     - fluctuations in construction and design costs; and

     - regional and general economic conditions.

     Due to these factors, quarterly revenues, expenses and results of
operations could vary significantly in the future. Because our operating results
may vary significantly from quarter to quarter based upon the factors described
above, results may not meet the expectations of analysts and investors, which
could negatively impact the trading market for your notes.

AN INCREASE IN INTEREST RATES COULD REDUCE OUR PROFITABILITY AND PREVENT US FROM
MAKING PAYMENTS ON THE NOTES WHEN DUE.

     A substantial portion of our existing indebtedness, including all of our
indebtedness under our senior credit facilities, bears interest at variable
rates. At June 30, 2000, we had variable rate debt of $285.8 million. We
currently hedge a portion of our exposure to fluctuations in interest rates. As
a result, we are vulnerable to interest rate fluctuations, and an increase in
interest rates could substantially increase our interest expense, which could in
turn reduce our profitability and could prevent us from making payments on the
notes when due.


A DECLINE IN THE WORK ASSIGNED TO US UNDER OUR MASTER SERVICE, TURNKEY AND OTHER
MAINTENANCE SERVICE AGREEMENTS WOULD REDUCE OUR REVENUE, WHICH COULD MAKE IT
DIFFICULT FOR US TO MAKE PAYMENTS ON THE NOTES.



     A significant decline in work assigned to us under our master service,
turnkey and other maintenance service agreements could reduce our revenue and
make it difficult for us to make payments on the notes. Under our master service
agreements, our customers have no obligation to undertake any installation
projects or other work with us. In addition, our customers may use their own
regularly employed personnel instead of us, which would reduce our revenue.
Therefore, despite the long-term nature of these master service agreements, they
do not give us the security that typical long-term contracts may provide.
Similarly, under our other maintenance agreements, our customers do not
generally guarantee us a particular amount of work.


IF WE ARE UNABLE TO ATTRACT AND RETAIN QUALIFIED EMPLOYEES, OR IF A SHORTAGE OF
LABOR INCREASES OUR LABOR COSTS SUBSTANTIALLY, OUR PROFITABILITY WOULD BE
REDUCED AND WE MIGHT NOT BE ABLE TO MAKE PAYMENTS ON THE NOTES.


     Our ability to provide high-quality services on a timely basis requires
that we employ an adequate number of skilled engineers, installation
technicians, equipment operators, linemen, foremen, cable and fiber splicers and
project managers. As projects are completed, we typically experience a high
turn-over rate among these employees. For the year ended December 31, 1999, we
experienced an employee turnover rate of 36% and, for the six month ended June
30, 2000, we experienced an employee turnover rate of 32%. Because we have been
able to recruit and train a sufficient number of employees, this turnover has
not had a material adverse effect on our business to date. However, if we are
unable to attract and retain a sufficient number of qualified employees in the
future, our profitability will be reduced and we might not be able to make
payments on the notes. We, like many of our competitors, are currently
experiencing shortages of qualified personnel. We may not be able to maintain
the skilled labor force necessary to operate efficiently and to support our
growth strategy. In addition, our labor expenses could increase as a result of a
shortage in the supply of skilled personnel. To the extent we cannot hire
employees on a full-time basis, we are often required to hire independent
contractors at rates higher than those we would pay to our own employees for
comparable work. As of June 30, 2000, we had approximately 1,800 subcontracted
workers. A substantial increase in our labor costs would also reduce our
profitability, which could prevent us from making payments on the notes.

TECHNOLOGICAL AND REGULATORY CHANGES COULD REDUCE DEMAND FOR OUR SERVICES AND
REDUCE OUR REVENUE, WHICH COULD PREVENT US FROM MAKING PAYMENTS ON THE NOTES.

     New technologies could reduce the need for installation, repair and
replacement of wireline services, which could reduce the demand for our
services, which would reduce our revenue and could prevent us from making
payments on the notes. The telecom industry is subject to rapid changes in
technology. Wireline systems used for the transmission of video, voice and data
are subject to potential displacement by various technologies, including
wireless technologies. We do not currently design, install or repair wireless
networks, although we intend to expand our service offerings to include these
services in the future. We may not be successful in developing or marketing our
services to wireless network operators. In addition, our customers may develop
new technologies that allow users to receive enhanced services without a
significant upgrade of their existing telecommunications networks. Additionally,
the telecom industry is subject to significant governmental regulation at the
federal, state and local levels. Regulatory changes in the telecom industry
could reduce the demand for our services. Due in part to changes in the
regulatory environment, the telecom industry has been characterized by a high
level of consolidation that may result in the loss of one or more customers.

BECAUSE SOME OF OUR COMPETITORS HAVE GREATER RESOURCES THAN WE DO AND BECAUSE
THERE ARE FEW BARRIERS TO ENTRY IN OUR INDUSTRY, WE MAY NOT BE ABLE TO MAINTAIN
AND ENHANCE OUR COMPETITIVE POSITION. IF WE ARE UNABLE TO DO SO, OUR BUSINESS
WILL NOT BE SUCCESSFUL AND WE WILL NOT BE ABLE TO MAKE PAYMENTS ON THE NOTES.

     Our industry is highly competitive and is served by numerous small,
owner-operated companies, a few large national companies and several large
regional companies. There are relatively few barriers to entry in our industry
and we expect that competition will intensify in the future. As a result, any
organization that has adequate financial resources and access to technical
expertise may become one of our competitors. We therefore may not be able to
maintain or enhance our competitive position. If we are unable to do so, our
business will not be successful and we will not be able to make payments on the
notes.

     Competition in the industry depends on a number of factors, including
price. Our competitors, particularly the smaller, owner-operated companies, may
have lower overhead cost structures and may, therefore, be able to provide their
services at lower rates than we can. Some of our competitors have greater market
presence, engineering and marketing capabilities, and financial, technological
and personnel resources than we do, including Dycom Industries, Inc., Mastec,
Inc., Quanta Services, Inc. and others. As a result, they may be able to develop
and expand their customer base more quickly, adapt more swiftly to new or
emerging technologies and changes in customer requirements, take advantage of
acquisition and other opportunities more readily, and devote greater resources
to the marketing and sale of their products and services than we can. In
addition, our competitive position within our industry would suffer if we were
to lose our status as a "preferred" service provider to our significant
customers. We also face competition from the in-house service organizations of
our existing or prospective customers who often employ personnel that perform
some of the same types of services as we do. Our revenues would decrease if
these customers increased the amount of services performed by their in-house
organizations, which could prevent us from making payments on the notes.

OUR CONTROLLING STOCKHOLDERS MAY MAKE DECISIONS THAT COULD ADVERSELY AFFECT THE
HOLDERS OF THE NOTES, SUCH AS DECISIONS TO ISSUE ADDITIONAL DEBT OR TO DECLARE
DIVIDENDS.

     Willis Stein & Partners owns capital stock representing approximately 42%
of the outstanding voting power of Parent. Willis Stein & Partners and all of
our other stockholders have entered into an investors agreement governing the
composition of Parent's board of directors. Willis Stein & Partners has the
right to designate a majority of the members of that board. As a result, Willis
Stein & Partners has the ability to appoint new management and approve any
action requiring the approval of Parent's stockholders and may make decisions
that could adversely affect the holders of the notes. For example, the directors
have the authority to make decisions affecting Parent's capital structure, and
Willis Stein may appoint directors

                                       18
<PAGE>   23

that would vote to issue additional indebtedness or declare dividends. The
interests of Willis Stein & Partners may not be the same as those of the holders
of the notes.

BECAUSE OUR SENIOR MANAGEMENT TEAM HAS AN AVERAGE OF OVER 20 YEARS OF EXPERIENCE
IN OUR INDUSTRY AND SIGNIFICANT ACQUISITION EXPERIENCE, THEY WOULD BE DIFFICULT
TO REPLACE. THE DEPARTURE OF KEY PERSONNEL COULD DISRUPT OUR BUSINESS AND REDUCE
OUR PROFITABILITY, WHICH COULD PREVENT US FROM MAKING PAYMENTS ON THE NOTES WHEN
DUE.

     We depend upon the continued services and experience of our senior
management team, including William J. Mercurio, our President and Chief
Executive Officer, and of the managers of businesses we acquire. Our executive
management and the senior management of our operating subsidiaries have an
average of over 20 years of experience in the telecom infrastructure services
industry. Our executive management team also has significant acquisition
experience. The loss of the services of any of our key employees, because they
would be difficult to replace, could disrupt our business plan and growth
strategy and reduce our profitability, which could prevent us from making
payments on the notes when due.

ENVIRONMENTAL AND SAFETY REQUIREMENTS COULD CAUSE US TO INCUR MATERIAL COSTS IN
THE FUTURE, WHICH COULD PREVENT US FROM MAKING PAYMENTS ON THE NOTES.

     We are subject to the requirements of federal, state and local
environmental and occupational health and safety laws and regulations. It is
possible that these requirements may change in the future. These requirements
are complex, constantly changing and have tended to become more stringent over
time. It is possible that we have not been and will not be at all times in
complete compliance with all of these requirements and that we could incur
material costs or liabilities in the future as a result of our noncompliance,
which could prevent us from making payments on the notes.


IN MAKING A DECISION WHETHER TO PARTICIPATE IN THE EXCHANGE OFFER, INVESTORS
SHOULD REALIZE THAT, DUE TO THE SIGNIFICANT NUMBER OF ACQUISITIONS THAT WE HAVE
COMPLETED OVER THE PAST TWO YEARS, OUR HISTORICAL FINANCIAL STATEMENTS ARE
GENERALLY NOT REFLECTIVE OF OUR ONGOING OPERATIONS.


     Since March 1998, we have acquired 18 companies, including the acquisition
of LISN in December 1999. All of these acquisitions were accounted for using the
purchase method of accounting. As a result, our historical financial statements
do not include the results of operations of acquisitions prior to the date they
were acquired. Due to the significant number of acquisitions that we have
completed over the last two years, our historical financial statements are not
reflective of our ongoing operations. In addition, prior to their acquisition by
us, many of the acquired companies were operated with different strategic and
financial objectives. Some of the former owners of the businesses we acquired
sought to maximize cash flow and stockholder distributions, rather than reinvest
earnings in future growth. In addition, our acquired businesses operated under
varying tax structures, which influenced the historical level of owners'
compensation. As a result, the historical financial statements of these acquired
businesses are generally not representative of their operations following their
acquisition.

                FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE

     All statements other than statements of present or historical facts, and
our opinions and beliefs relating to these statements, included in this
prospectus, including, without limitation, statements regarding our future
financial position, business strategy, budgets, projected costs and plans and
objectives of management for future operations, are forward-looking statements.
In addition, forward-looking statements generally can be identified by the use
of forward-looking terminology such as "may," "will," "expect," "intend,"
"estimate," "anticipate," "believe" or "continue" or the negative thereof or
other variations of this terminology or similar terminology. All subsequent
written and oral forward-looking statements attributable to us, or persons
acting on our behalf, are expressly qualified in their entirety by the
cautionary statements. Although we believe that the expectations reflected in
our forward-looking statements are reasonable, we can give no assurance that
these expectations will prove to have been correct. Important factors that could
cause actual results to differ materially from our expectations are disclosed
under "Risk Factors" and elsewhere in this prospectus, including, among others:

     - our substantial debt and significant debt service obligations;

     - changes in the laws and regulations governing the telecom industry;

     - the competitive nature of the telecom infrastructure industry;

     - changes in our relationships with our major customers;

     - changes in technology that could reduce demand for our services;

     - our ability to attract and retain qualified key employees; and

     - our ability to successfully integrate acquired businesses, including
       LISN.

                                LISN ACQUISITION

     On December 15, 1999, Parent and LISN entered into a series of transactions
that resulted in LISN becoming a wholly owned subsidiary of NATG. In connection
with the LISN acquisition, Parent was acquired by an investor group consisting
of LISN's former stockholders, including Willis Stein & Partners and members of
LISN's management, new co-investors and members of Parent's and its
subsidiaries' management. The principal components of the LISN acquisition
included:

     - Additional Investment. Willis Stein & Partners, a group of co-investors
       and members of LISN's management invested cash in the aggregate of $112.2
       million in LISN immediately prior to the exchange described below.

     - Exchange of LISN Securities. LISN's former stockholders, including Willis
       Stein & Partners and members of LISN's management, exchanged all of their
       outstanding junior subordinated notes, preferred stock and common stock
       of LISN for a similar strip of securities issued by Parent.

     - Borrowings. NATG borrowed: (1) approximately $275.0 million, excluding
       $9.3 million under standby letters of credit described below, under the
       new multi-tranche senior credit facilities providing for aggregate
       borrowings of up to $375.0 million, consisting of a (i) $100.0 million
       revolving credit facility to be used for permitted acquisitions and
       working capital, with sublimits of $75.0 million for acquisition loans
       and $50.0 million for working capital loans, (ii) $75.0 million tranche A
       term loan, with a $50.0 million letter of credit subfacility and (iii)
       $200.0 million tranche B term loan, and (2) $100.0 million under a senior
       subordinated term loan.

     - Redemption of Parent Securities. We redeemed all of Parent's outstanding
       capital stock other than a portion of the capital stock owned by members
       of Parent's or its subsidiaries' management and the securities issued to
       LISN's former stockholders.

     - Rollover of Parent Equity. Substantially all of Parent's management
       stockholders rolled over approximately one-half the value of their equity
       interests in Parent. As part of the rollover, Parent's stockholders
       exchanged a portion of their existing common stock for newly issued
       junior subordinated notes and preferred stock of Parent.

     - Repayment of Existing Indebtedness. NATG repaid an aggregate of $179.8
       million of indebtedness of its subsidiaries and $82.3 million of LISN's
       indebtedness.

     We refer to all of the foregoing transactions and payment of all of the
fees and expenses associated with these transactions collectively as the LISN
acquisition.

     Following the LISN acquisition, the investor group led by Willis Stein &
Partners will own capital stock representing approximately 65% of Parent's
voting power and the management of Parent and its subsidiaries, including LISN,
will own capital stock representing approximately 35% of Parent's voting power.

     The LISN acquisition resulted in each stockholder of Parent owning Parent
common stock, series C preferred stock and junior subordinated notes, with
values representing approximately 9%, 54% and 37%, respectively, of the fair
market value of the securities. For more information regarding the terms of
Parent's common stock, preferred stock and junior subordinated notes, see
"Description of Parent's Securities."

                      EXCHANGE OFFER; REGISTRATION RIGHTS

     The issuers, the guarantors and the initial purchasers entered into a
registration rights agreement in connection with the original issuance of the
notes. The registration rights agreement provides that we will, take the
following actions at our expense, for the benefit of the holders of the notes.

     - Within 120 days after the date on which the outstanding notes were
issued, we will file the exchange offer registration statement, of which this
prospectus is a part, relating to the exchange offer. The exchange notes will
have terms substantially identical in all material respects to the outstanding
notes except that the exchange notes will not contain transfer restrictions.

     - We will cause the exchange offer registration statement to be declared
effective under the Securities Act within 210 days after the date on which the
outstanding notes were issued.

     - We will keep the exchange offer open for at least 20 business days, or
longer if required by applicable law, after the date notice of the exchange
offer is mailed to the holders.

     For each of the outstanding notes surrendered in the exchange offer, the
holder who surrendered the note will receive an exchange note having a principal
amount equal to that of the surrendered note. Interest on each exchange note
will accrue from the later of (1) the last interest payment date on which
interest was paid on the outstanding note surrendered. (2) if no interest has
been paid on the outstanding note, from the date on which the outstanding notes
were issued. If the note is surrendered for exchange on a date in a period that
includes the record date for an interest payment date to occur on or after the
date of the exchange will accrue from that interest payment date.

     Under existing interpretations of the SEC contained in several no-action
letters to third parties, the exchange notes will be freely transferable by
holders of the notes, other than our affiliates, after the exchange offer
without further registration under the Securities Act. However, each holder that
wishes to exchange its outstanding notes for exchange notes will be required to
make the following representations.

     - Any exchange notes to be received by the holder will be acquired in the
ordinary course of its business.

     - At the time of the commencement of the exchange offer, the holder has no
arrangement or understanding with any person to participate in the distribution,
within the meaning of Securities Act, of the exchange notes in violation of the
Securities Act.

     - The holder is not our affiliate as defined in Rule 405 promulgated under
Securities Act.

     - If the holder is not a broker-dealer, it is not engaged in, and does not
intend to engage in, the distribution of exchange notes.

     - If the holder is a broker-dealer that will receive exchange notes for its
own account in exchange for outstanding notes that were acquired as a result of
market-making or other trading activities, the holder will deliver a prospectus
in connection with any resale of the exchange notes. We refer to these broker-
dealers as participating broker-dealers.

     - The holder is not acting on behalf of any person or entity that could not
truthfully make these representations.

     We will agree to make available, during the period required by the
Securities Act, a prospectus meeting the requirements of the Securities Act for
use by participating broker-dealers and any other persons with similar
prospectus delivery requirements for use in connection with any resale of
exchange notes.

     We will be required to file a shelf registration statement covering resales
of the outstanding notes if:

     (1) because of any change in law or in currently prevailing interpretations
of the staff of the SEC, we are not permitted to effect an exchange offer,

                                       24
<PAGE>   29

     (2) the exchange offer is not consummated within 255 days of the date on
which the outstanding notes were issued,

     (3) in some circumstances, the holders of unregistered exchange notes so
request, or

     (4) in the case of any holder that participates in the exchange offer, the
holder does not receive exchange notes on the date of the exchange that may be
sold without restriction under state and federal securities laws.

     In addition, we have agreed to use our best efforts to keep effective the
shelf registration statement until the earlier of two years after the date on
which the outstanding notes were issued or the time when all of the applicable
notes have been sold under the shelf registration statement.

     We will, in the event that a shelf registration statement is filed, provide
to each holder copies of the prospectus that is a part of the shelf registration
statement, notify each holder when the shelf registration statement for the
outstanding notes has become effective and take other actions as are required to
permit unrestricted resales of the outstanding notes. A holder that sells
outstanding notes that were registered on the shelf registration statement,

     - will 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 applicable civil liability provisions under Securities
       Act in connection with the sales, and

     - will be bound by the provisions of the registration rights agreement that
       are applicable to the holder, including indemnification rights and
       obligations.

     If we fail to comply with any of the above provisions or if the exchange
offer registration statement or the shelf registration statement fails to become
effective, then, as liquidated damages, additional interest will become payable
in respect of the outstanding notes as calculated below.

     (1) If

          (A) neither the exchange offer registration statement nor the shelf
     registration statement is filed with the SEC on or prior to 120 days after
     the date on which the outstanding notes were issued or

          (B) notwithstanding that we have consummated or will consummate an
     exchange offer, we are required to file a shelf registration statement and
     the shelf registration statement is not filed on or prior to the date
     required by the registration rights agreement,

     then commencing on the day after the required filing date, additional
interest shall accrue on the principal amount of the notes. Additional interest
will accrue at a rate of 0.5% per annum for the first 90 days immediately
following the required filing date, and the additional interest rate will
increase by an additional 0.5% per annum at the beginning of each subsequent
90-day period.

     (2) If

          (A) neither the exchange offer registration statement nor a shelf
     registration statement is declared effective by the 210th day after the
     date on which the outstanding notes were issued or, with respect to any
     shelf registration statement, the later of the 60th day after the date the
     shelf registration was filed or the 210th day after the date on which
     outstanding notes were issued, or

          (B) notwithstanding that we have consummated or will consummate an
     exchange offer, we are required to file a shelf registration statement and
     the shelf registration statement is not declared effective by the SEC on or
     prior to the relevant effectiveness date,

     then, commencing on the day after either the required effectiveness date,
additional interest will accrue on the principal amount of the notes. Additional
interest will accrue at a rate of 0.5% per annum for the first 90 days
immediately following the required effectiveness date, and the additional
interest rate

                                       25
<PAGE>   30


will increase by an additional 0.5% per annum at the beginning of each
subsequent 90-day period. Because this registration statement was not declared
effective by the SEC by September 6, 2000, which was the 210th day following the
issuance of the outstanding notes, we have begun to incur additional interest on
the outstanding notes, as liquidated damages, at a rate of 0.5% per annum.



     (3) If



          (A) the issuers have not exchanged exchange notes for all securities
     validly tendered in the exchange offer on or prior to the 30th day after
     the effective date of the exchange offer registration statement,


          (B) if applicable, a shelf registration statement has been declared
     effective and the shelf registration statement ceases to be effective at
     any time during the effectiveness period, or

          (C) we effect a suspension period in accordance with the terms of the
     registration rights agreement,

     then in each case, additional interest will accrue on the principal amount
of the notes. Additional interest will accrue at a rate of 0.50% per annum for
the first 90 days commencing on the

     - 31st day after the effective date, in the case of (A) above,

     - the day the shelf registration statement ceases to be effective in the
       case of (B) above or

     - the day the suspension period commences in the case of (C) above.

     The additional interest rate will increase by an additional 0.50% per annum
at the beginning of each subsequent 90-day period.

     The additional interest rate on the notes may not accrue under more than
one of clauses (1) through (3) above at any one time and at no time can the
aggregate amount of additional interest accruing exceed in the aggregate 1.5%
per annum. In addition, upon

     - the filing of the exchange offer registration statement or a shelf
       registration statement in the case of clause (1) above,

     - the effectiveness of the exchange offer registration statement or a shelf
       registration statement in the case of clause (2) above, or

     - the exchange of the applicable exchange notes for all notes tendered, in
       the case of clause (3)(A) above,

     - the effectiveness of the applicable shelf registration statement which
       had ceased to remain effective, in the case of clause (3)(B) above, or

     - the termination of the suspension period, in the case of clause (3)(C)
       above,

     additional interest on the notes shall cease to accrue. Any amounts of
additional interest due as a result of the circumstances described in clause
(1), (2) or (3) above will be payable in cash on the same original interest
payment dates as the notes.

     Following the consummation of the exchange offer, holders of the
outstanding notes who were eligible to participate in the exchange offer but who
did not tender their outstanding notes will not have any further registration
rights and the outstanding notes will continue to be subject to restrictions on
transfer. Accordingly, the liquidity of the market for the outstanding notes
could be adversely affected.

                                       26

TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, we will accept any and all outstanding notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
the expiration date of the exchange offer. We will issue $1,000 principal amount
of exchange notes in exchange for each $1,000 principal amount of outstanding
notes accepted in the exchange offer. Holders may tender some or all of their
outstanding notes in the exchange offer. However, outstanding notes may be
tendered only in integral multiples of $1,000.

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

     (1) the exchange notes bear a Series B designation and a different CUSIP
Number from the outstanding notes;

     (2) the exchange notes have been registered under the Securities Act and
will not bear legends restricting their transfer; and

     (3) the holders of the exchange notes will not be entitled to any rights
under the registration rights agreement, including the provisions providing for
an increase in the interest rate on the outstanding notes in certain
circumstances relating to the timing of the exchange offer, all of which rights
will terminate when the exchange offer is terminated.

The exchange notes will evidence the same debt as the outstanding notes and will
be entitled to the benefits of the indenture.


     As of the date of this prospectus, $150,000,000 aggregate principal amount
of the outstanding notes were outstanding. We have fixed the close of business
on September 13, 2000 as the record date for the exchange offer for purposes of
determining the persons to whom this prospectus and the letter of transmittal
will be mailed initially.


     Holders of outstanding notes do not have any appraisal or dissenters'
rights under the General Corporation Law of Delaware, or the indenture in
connection with the exchange offer. We intend to conduct the exchange offer in
accordance with the applicable requirements of the Exchange Act and the rules
and regulations of the SEC.

     We will be deemed to have accepted validly tendered outstanding notes when,
as and if we have given oral or written notice of our acceptance to the exchange
agent. The exchange agent will act as agent for the tendering holders for the
purpose of receiving the exchange notes from us.

     If any tendered outstanding notes are not accepted for exchange because of
an invalid tender, the occurrence of specified other events set forth in this
prospectus or otherwise, the certificates for any unaccepted outstanding notes
will be returned, without expense, to the tendering holder as promptly as
practicable after the expiration date of the exchange offer.

     Holders who tender outstanding notes in 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
outstanding as part of the exchange offer. We will pay all charges and expenses,
other than transfer taxes in certain circumstances, in connection with the
exchange offer. See "-- Fees and Expenses."

EXPIRATION DATE; EXTENSIONS; AMENDMENTS


     The term "expiration date" will mean 5:00 p.m., New York City time, on
October 16, 2000, unless we, in our sole discretion, extend the exchange offer,
in which case the term "expiration date" will mean the latest date and time to
which the exchange offer is extended.


                                       27
<PAGE>   32

     In order to extend the exchange offer, we will notify the exchange agent of
any extension by oral or written notice and will mail to the registered holders
an announcement, each prior to 9:00 a.m., New York City time, on the next
business day after the previously scheduled expiration date.

     We reserve the right, in our sole discretion,

     (1) to delay accepting any outstanding notes, to extend the exchange offer
or to terminate the exchange offer if any of the conditions set forth below
under "-- Conditions" have not been satisfied, by giving oral or written notice
of any delay, extension or termination to the exchange agent or

     (2) to amend the terms of the exchange offer in any manner.

Any delay in acceptance, extension, termination or amendment will be followed as
promptly as practicable by oral or written notice to the registered holders.

INTEREST ON THE EXCHANGE NOTES

     The exchange notes will bear interest from their date of issuance. Holders
of outstanding notes that are accepted for exchange will receive, in cash,
accrued interest to, but not including, the date of issuance of the exchange
notes. Interest on the outstanding notes accepted for exchange will cease to
accrue upon issuance of the exchange notes.

     Interest on the exchange notes is payable semi-annually on each February 1
and August 1, commencing on August 1, 2000.

PROCEDURES FOR TENDERING

     Only a holder of outstanding notes may tender outstanding notes in the
exchange offer. To tender in the exchange offer, a holder must:

     (1) complete, sign and date the letter of transmittal, or a facsimile of
the letter of transmittal,

     (2) have the signatures on the letter of transmittal guaranteed if required
by the letter of transmittal or transmit an agent's message in connection with a
book-entry transfer, and

     (3) mail or otherwise deliver the letter of transmittal or the facsimile,
together with the outstanding notes and any other required documents, to the
exchange agent prior to 5:00 p.m., New York City time, on the expiration date.

     To be tendered effectively, the outstanding notes, letter of transmittal or
an agent's message and other required documents must be completed and received
by the exchange agent at the address set forth below under "Exchange Agent"
prior to 5:00 p.m., New York City time, on the expiration date. Delivery of the
outstanding notes may be made by book-entry transfer in accordance with the
procedures described below. Confirmation of the book-entry transfer must be
received by the exchange agent prior to the expiration date.

     The term "agent's message" means a message, transmitted by a book-entry
transfer facility to, and received by, the exchange agent forming a part of a
confirmation of a book-entry, which states that the book-entry transfer facility
has received an express acknowledgment from the participant in the book-entry
transfer facility tendering the outstanding notes that the participant has
received and agrees:

     - to participate in ATOP;

     - to be bound by the terms of the letter of transmittal; and

     - that we may enforce the agreement against the participant.

     By executing the letter of transmittal, each holder will make to us the
representations set forth above in the third paragraph under the heading
"-- Purpose and Effect of the Exchange Offer."

                                       28
<PAGE>   33

     The tender by a holder and our acceptance of the tender will constitute
agreement between the holder and us in accordance with the terms and subject to
the conditions set forth in this prospectus and in the letter of transmittal or
agent's message.

     THE METHOD OF DELIVERY OF OUTSTANDING NOTES AND THE LETTER OF TRANSMITTAL
OR AGENT'S MESSAGE AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT
THE ELECTION AND SOLE RISK OF THE HOLDER. AS AN ALTERNATIVE TO DELIVERY BY MAIL,
HOLDERS MAY WISH TO CONSIDER OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD
BE SENT TO US. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR THEM.

     Any beneficial owner whose outstanding notes are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct the
registered holder to tender on the beneficial owner's behalf. See "Instructions
to Registered Holder and/or Book-Entry Transfer Facility Participant from
Beneficial Owner" included with the letter of transmittal.

     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by a member of the Medallion System unless the
outstanding notes are tendered:

     (1) by a registered holder who has not completed the box entitled "Special
Registration Instructions" or "Special Delivery Instructions" on the letter of
transmittal or

     (2) for the account of a member firm of the Medallion System.

     In the event that signatures on a letter of transmittal or a notice of
withdrawal, as the case may be, are required to be guaranteed, the guarantee
must be by a member firm of the Medallion System.

     If the letter of transmittal is signed by a person other than the
registered holder, the outstanding notes must be endorsed or accompanied by a
properly completed bond power, signed by the registered holder as the registered
holder's name appears on the outstanding notes with the signature on the bond
power guaranteed by a member firm of the Medallion System.

     If the letter of transmittal or any outstanding notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
offices of corporations or others acting in a fiduciary or representative
capacity, the person signing should so indicate when signing, and evidence
satisfactory to us of its authority to so act must be submitted with the letter
of transmittal.

     We understand that the exchange agent will make a request promptly after
the date of this prospectus to establish accounts with respect to the
outstanding notes at DTC for the purpose of facilitating the exchange offer.
Subject to the establishment of the accounts, any financial institution that is
a participant in DTC's system may make book-entry delivery of outstanding notes
by causing DTC to transfer the outstanding notes into the exchange agent's
account with respect to the outstanding notes in accordance with DTC's
procedures for the transfer. Although delivery of the outstanding notes may be
effected through book-entry transfer into the exchange agent's account at DTC,
unless an agent's message is received by the exchange agent in compliance with
ATOP, an appropriate letter of transmittal properly completed and duly executed
with any required signature guarantee and all other required documents must in
each case be transmitted to and received or confirmed by the exchange agent at
its address set forth below on or prior to the expiration date, or, if the
guaranteed delivery procedures described below are complied with, within the
time period provided under the procedures. Delivery of documents to DTC does not
constitute delivery to the exchange agent.

     All questions as to the validity, form, eligibility, including time of
receipt, acceptance of tendered outstanding notes and withdrawal of tendered
outstanding notes will be determined by us in our sole discretion, which
determination will be final and binding. We reserve the absolute right to reject
any and

                                       29
<PAGE>   34

all outstanding notes not properly tendered or any outstanding notes our
acceptance of which would, in the opinion of our counsel, be unlawful.

     We also reserve the right in our sole discretion to waive any defects,
irregularities or conditions of tender as to particular outstanding notes. Our
interpretation of the terms and conditions of the exchange offer, including the
instructions in the letter of transmittal, will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of outstanding notes must be cured within the time we determine. Although we
intend to notify holders of defects or irregularities with respect to tenders of
outstanding notes, neither we, the exchange agent nor any other person will
incur any liability for failure to give the notification. Tenders of outstanding
notes will not be deemed to have been made until the defects or irregularities
have been cured or waived. Any outstanding notes received by the exchange agent
that are not properly tendered and as to which the defects or irregularities
have not been cured or waived will be returned by the exchange agent to the
tendering holders, as soon as practicable following the expiration date.

GUARANTEED DELIVERY PROCEDURES

     Holders who wish to tender their outstanding notes and:

     (1) whose outstanding notes are not immediately available,

     (2) who cannot deliver their outstanding notes, the letter of transmittal
or any other required documents to the exchange agent or

     (3) who cannot complete the procedures for book-entry transfer, prior to
the expiration date, may effect a tender if the following conditions are met:

          (A)  The tender is made through a member firm of the Medallion System.

          (B)  Prior to the expiration date, the exchange agent receives from a
     member firm of the Medallion System a properly completed and duly executed
     Notice of Guaranteed Delivery by facsimile transmission, mail or hand
     delivery setting forth the name and address of the holder, the certificate
     number(s) of the outstanding notes and the principal amount of outstanding
     notes tendered. The Notice of Guaranteed Delivery must state that tender is
     being made and must guarantee that, within three New York Stock Exchange
     trading days after the expiration date, the letter of transmittal or
     facsimile of the letter of transmittal, together with the certificate(s)
     representing the outstanding notes or a confirmation of book-entry transfer
     of the outstanding notes into the exchange agent's account at DTC, and any
     other documents required by the letter of transmittal will be deposited by
     the member firm of the Medallion System with the exchange agent.


          (C) The properly completed and executed letter of transmittal or a
     facsimile of the letter of transmittal, as well as the certificate(s)
     representing all tendered outstanding notes in proper form for transfer or
     a confirmation of book-entry transfer of the outstanding notes into the
     exchange agent's account at DTC, and all other documents required by the
     letter of transmittal are received by the exchange agent within three New
     York Stock Exchange trading days after the expiration date.


     Upon request to the exchange agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their outstanding notes by complying with the
guaranteed delivery procedures set forth above.

WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, tenders of outstanding
notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on
the expiration date.

                                       30
<PAGE>   35

     To withdraw a tender of outstanding notes, a telegram, telex, letter or
facsimile transmission notice of withdrawal must be received by the exchange
agent at its address set forth in this prospectus prior to 5:00 p.m., New York
City time, on the expiration date of the exchange offer. Any notice of
withdrawal must:

     (1)  specify the name of the person having deposited the outstanding notes
to be withdrawn;

     (2)  identify the outstanding notes to be withdrawn, including the
certificate number(s) and principal amount of the outstanding notes, or, in the
case of outstanding notes transferred by book-entry transfer, the name and
number of the account at DTC to be credited;

     (3)  be signed by the holder in the same manner as the original signature
on the letter of transmittal by which the outstanding notes were tendered,
including any required signature guarantees, or be accompanied by documents of
transfer sufficient to enable the trustee to register the transfer of the
outstanding notes into the name of the person withdrawing the tender; and

     (4)  specify the name in which any outstanding notes are to be registered,
if different from that of the person depositing the outstanding notes to be
withdrawn.

     All questions as to the validity, form and eligibility, including time of
receipt, of the notices will be determined by us and our determination will be
final and binding on all parties. Any outstanding notes so withdrawn will be
deemed not to have been validly tendered for purposes of the exchange offer and
no exchange notes will be issued with respect to the withdrawn notes unless they
are validly retendered. Any outstanding notes which have been tendered but which
are not accepted for exchange will be returned to their holder without cost to
the holder as soon as practicable after withdrawal, rejection of tender or
termination of the exchange offer. Properly withdrawn outstanding notes may be
retendered by following one of the procedures described above under
"--Procedures for Tendering" at any time prior to the expiration date.

CONDITIONS

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

     (1)  any action or proceeding is instituted or threatened in any court or
by or before any governmental agency with respect to the exchange offer which,
in our sole judgment, might materially impair our ability to proceed with the
exchange offer or any material adverse development has occurred in any existing
action or proceeding with respect to us or any of our subsidiaries; or

     (2)  any law, statute, rule, regulation or interpretation by the Staff of
the SEC is proposed, adopted or enacted, which, in our sole judgment, might
materially impair our ability to proceed with the exchange offer or materially
impair the contemplated benefits of the exchange offer to us; or

     (3)  any governmental approval has not been obtained, which approval we, in
our sole discretion, deem necessary for the consummation of the exchange offer
as contemplated by this prospectus.

     If we determine in our sole discretion that any of the conditions are not
satisfied, we may

     (1) refuse to accept any outstanding notes and return all tendered
outstanding notes to the tendering holders,

     (2) extend the exchange offer and retain all outstanding notes tendered
prior to the expiration of the exchange offer, subject, however, to the rights
of holders to withdraw the outstanding notes or

     (3) waive the unsatisfied conditions with respect to the exchange offer and
accept all properly tendered outstanding notes which have not been withdrawn.

DELIVERY TO AN ADDRESS OTHER THAN SET FORTH ABOVE WILL NOT CONSTITUTE A VALID
DELIVERY.

FEES AND EXPENSES

     We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail. However, additional solicitation may be made by
telegraph, telecopy, telephone or in person by our and our affiliates' officers
and regular employees.

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

     We will pay the cash expenses to be incurred in connection with the
exchange offer. These expenses include fees and expenses of the exchange agent
and trustee, accounting and legal fees and printing costs, among others.

ACCOUNTING TREATMENT

     The exchange notes will be recorded at the same carrying value as the
outstanding notes, which is face value, as reflected in our accounting records
on the date of exchange. Accordingly, we will not recognize any gain or loss for
accounting purposes as a result of the exchange offer. The expenses of the
exchange offer will be deferred and charged to expense over the term of the
exchange notes.

CONSEQUENCES OF FAILURE TO EXCHANGE

     The outstanding notes that are not exchanged for exchange notes in the
exchange offer will remain restricted securities. Therefore, the outstanding
notes may be resold only:

     (1) to us upon redemption of the notes or otherwise;

     (2) so long as the outstanding notes are eligible for resale under Rule
144A, to a person inside the United States whom the seller reasonably believes
is a qualified institutional buyer within the meaning of Rule 144A under the
Securities Act in a transaction meeting the requirements of Rule 144A, in
accordance with Rule 144 under the Securities Act, or in compliance with another
exemption from the

                                       32
<PAGE>   37

registration requirements of the Securities Act, which other exemption is based
upon an opinion of counsel reasonably acceptable to us;

     (3) outside the United States to a foreign person in a transaction meeting
the requirements of Rule 904 under the Securities Act; or

     (4) if registered on an effective registration statement under the
Securities Act,

     in each case in accordance with any applicable securities laws of any state
of the United States.

RESALE OF THE EXCHANGE NOTES

     With respect to resales of exchange notes, based on interpretations by the
Staff of the SEC set forth in no-action letters issued to third parties, we
believe that a holder or other person who receives exchange notes, whether or
not the person is the holder will be allowed to resell the exchange notes to the
public without further registration under the Securities Act and without
delivering to the purchasers of the exchange notes a prospectus that satisfies
the requirements of Section 10 of the Securities Act.

     In order to resell the exchange notes without restriction, the holder of
exchange notes:

     - must not be our affiliate within the meaning of Rule 405 under the
       Securities Act

     - must have received the exchange notes in exchange for outstanding notes
       in the ordinary course of business and

     - must not participate or intend to participate, or have any arrangement or
       understanding with any person to participate, in the distribution of the
       exchange notes.

     However, if any holder acquires exchange notes in the exchange offer for
the purpose of distributing or participating in a distribution of the exchange
notes, the holder cannot rely on the position of the Staff of the SEC expressed
in the no-action letters or any similar interpretive letters, and must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale transaction, unless an exemption from registration
is otherwise available. Further, each broker-dealer that receives exchange notes
for its own account in exchange for outstanding notes, where the outstanding
notes were acquired by the 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 the exchange notes.

                                USE OF PROCEEDS

     This exchange offer is intended to satisfy our obligations under the
registration rights agreement. We will not receive any cash proceeds from the
issuance of the exchange notes. In consideration for issuing the exchange notes
contemplated in this prospectus, we will receive outstanding notes in like
principal amount, the form and terms of which are the same as the form and terms
of the exchange notes, except as otherwise described in this prospectus.

     The net proceeds from the issuance of the outstanding notes, after
deducting the underwriting discount and expenses, was $143.6 million. We used a
portion of these proceeds to repay $100.0 million in aggregate principal amount
outstanding under the senior subordinated term loan, plus accrued interest. We
used the remaining $43.6 to repay a portion of the tranche B term loan at 101%
of the principal amount repaid, plus accrued interest. As of December 31, 1999,
the interest rate on borrowings under the senior subordinated term loan was
12.4% and the interest rate on borrowings under the tranche B term loan was
9.4%. The borrowings under the senior subordinated term loan were due and
payable on December 15, 2007. The tranche B term loan is payable in quarterly
installments, with the final installment due December 15, 2006. The proceeds
from the senior subordinated term loan and the tranche B term loan were used to
finance a portion of the LISN acquisition. See "LISN Acquisition,"
"Capitalization" and "Description of Senior Credit Facilities."

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS

     Set forth below are unaudited pro forma financial statements for Orius. The
unaudited pro forma financial statements have been prepared by the application
of pro forma adjustments to the historical financial statements of LISN, Orius
and each of the Acquired Companies. Orius acquired eight businesses in 1998, six
in 1999 and completed the acquisitions of Irwin, Fenix, Midwest Splicing and
Hattech in 2000. The unaudited pro forma financial statements have been prepared
to reflect LISN as the acquiring corporation for accounting purposes in the LISN
acquisition even though it became a subsidiary of Orius in that transaction.
LISN has been treated as the acquiring corporation for accounting purposes as a
result of LISN's former stockholders acquiring control of Parent in the LISN
acquisition.

     The unaudited pro forma financial statements presented below are intended
to give you a better understanding of what the results of operations of all of
our businesses might have been had they been combined as of the beginning of the
periods presented. Our combined financial position at June 30, 2000 is reflected
in our historical balance sheet included elsewhere in this prospectus. We
prepared the unaudited pro forma statements of operations data by (1) combining
the historical results of LISN, Orius and each of the Acquired Companies as if
LISN had acquired Orius and each of the Acquired Companies at the beginning of
the period presented and (2) adjusting the combined historical results to
reflect:

        (a) the application of purchase accounting to those acquisitions,

        (b) the elimination of certain non-recurring expenses and adjustments
            reflecting different depreciation and amortization policies and

        (c) the financing transactions associated with those acquisitions.

     The application of purchase accounting to the businesses acquired by Orius
resulted in certain fair value adjustments to property, plant and equipment and
these are reflected in the Supplemental Unaudited Pro Forma Financial Data. Upon
the LISN acquisition, no other fair value adjustment was necessary. The
amortization of goodwill as a result of the LISN acquisition is included as if
LISN had acquired Orius at the beginning of all periods presented.

     LISN, Orius and the Acquired Companies may have performed differently if
they had been combined as of or on the dates presented. You should not rely on
these unaudited pro forma financial statements as being indicative of the
historical results that we would have had or the future results that we will
experience.

     You should read these unaudited pro forma financial statements in
conjunction with the information contained in "Selected Historical Financial
Data," "Management's Discussion and Analysis of Financial Condition and Results
of Operations" and "Supplemental Unaudited Pro Forma Financial Data" and the
financial statements and the related notes appearing elsewhere in this
prospectus.

              NOTES TO UNAUDITED PRO FORMA STATEMENT OF OPERATIONS
                             (DOLLARS IN THOUSANDS)

(1) Results for the year ended December 31, 1999 represent the combined
    historical results for the period of LISN (which had no material operations
    prior to 1998) and LISN, Inc. and Orius from December 15, 1999 through
    December 31, 1999. LISN and ARION, Inc., which were companies under common
    control, were combined in the May 1999 recapitalization.

(2) Results for the period ended December 14, 1999 represent the actual
    historical consolidated results of Orius, including results for the Acquired
    Companies from their date of acquisition.

(3) Represents the results of the Acquired Companies in the related period prior
    to the date of acquisition and related acquisition adjustments. See
    "Supplemental Unaudited Pro Forma Financial Data" for further detail and
    discussion.

(4) Reflects the decrease resulting from differentials between the compensation
    levels of the former owners of LISN and the terms of their employment
    agreements entered into with Parent. After the acquisition of LISN, the
    duties and responsibilities of the owners who remained employed with the
    Company have not and will not change and additional costs have not and are
    not expected to be incurred related to their efforts.

(5) Reflects the elimination of one-time expenses associated with the LISN
    acquisition included in Orius' historical statement of operations. As the
    acquired company for accounting purposes, Orius reflected these costs as
    expenses in the period incurred. Included in this adjustment are
    professional fees totaling $6,248 for advisors, lawyers and accountants, and
    compensation expense of $5,814 associated with the accelerated vesting of
    options under Parent's stock option plan at the time of the LISN
    acquisition.

(6) The calculation of pro forma depreciation reflecting fixed asset basis
    adjustments from the application of purchase accounting is included in Note
    3 to the Supplemental Unaudited Pro Forma Financial Data for the Acquired
    Companies. While these basis adjustments reflect the purchase accounting at
    the time of Orius' acquisition of these businesses, given the nature of the
    fixed assets and the proximity of the acquisitions, book value approximated
    fair value at the time of the LISN Acquisition. Pro forma amortization of
    goodwill generated from the LISN acquisition and the acquisition of the
    Acquired Companies based on a 25-year goodwill life is calculated as
    follows:

                SUPPLEMENTAL UNAUDITED PRO FORMA FINANCIAL DATA

     Set forth below is supplemental unaudited pro forma financial data for the
Acquired Companies. The supplemental unaudited pro forma financial data has been
derived by the application of pro forma adjustments to the historical financial
statements of each of the Acquired Companies. Orius acquired eight businesses in
1998, six in 1999 and completed the acquisition of Irwin in January 2000, the
acquisitions of Fenix and Midwest Splicing in April 2000 and the acquisition of
Hattech in May 2000.

     The supplemental unaudited pro forma financial data presented below is
intended to give you additional information as to how the amounts set forth in
the unaudited pro forma statement of income under the column "Acquired
Companies" in the Unaudited Pro Forma Financial Statements were calculated. We
obtained the pro forma statements of operations data by (1) combining the
historical results of each of the Acquired Companies from the beginning of the
period until their acquisition by Orius and (2) adjusting the combined
historical results to reflect (a) the application of purchase accounting to the
acquisitions, (b) the elimination of certain non-recurring expenses and
adjustments reflecting different depreciation and amortization policies and (c)
the financing transactions associated with the acquisitions. The Acquired
Companies may have performed differently if they had been combined as of or on
the dates presented. You should not rely on the supplemental unaudited pro forma
data as being indicative of the historical results that we would have had or the
future results that we will experience.

     You should read this supplemental unaudited pro forma financial data in
conjunction with the information contained in "Unaudited Pro Forma Financial
Statements," "Selected Historical Financial Data," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the financial
statements and the related notes appearing elsewhere in this prospectus.

     (i) Reflects the decrease resulting from differentials between the
         compensation levels of former owners of the Acquired Companies and the
         terms of their employment agreements with Orius. After the acquisition
         of the Acquired Companies, the duties and responsibilities of the
         owners who remained employed with Orius have not and will not change,
         and additional costs have not and are not expected to be incurred
         related to their efforts. Also reflects the elimination of compensation
         expense associated with the distribution of excess cash balances to the
         former owners of the Acquired Companies immediately prior to their
         dates of acquisition.

    (ii) Reflects the rent expense resulting from our current lease terms as
         compared to lease terms entered into by former owners. In addition,
         reflects the increase in rent expense and the corresponding decrease in
         real estate tax expense resulting from our leasing rather than owning
         certain related facilities which were not, and in the case of Irwin
         will not be, purchased from the former owners of the Acquired
         Companies.

(4) Depreciation has been derived utilizing the property, plant and equipment
    values of each of the Acquired Companies at the time of their acquisition,
    rather than utilizing values of property, plant and equipment actually held
    by each of the Acquired Companies in the period presented. Reflects the
    impact on depreciation resulting from (1) the application of Orius'
    depreciation policy rather than those of the former owners of the Acquired
    Companies and (2) any decrease in depreciation resulting from leasing rather
    than owning certain related facilities.

    The acquisition adjustments to depreciation and amortization expense consist
    of the following:

(1) Results for the year ended December 31, 1999 represent the results of the
    Acquired Companies purchased in the related period prior to their date of
    acquisition.

(2) The acquisition adjustments to general and administrative expenses consist
    of the following:

     (i) Reflects the decrease resulting from differentials between the
         compensation levels of former owners of the Acquired Companies and the
         terms of their employment agreements with Orius. After the acquisition
         of the Acquired Companies, the duties and responsibilities of the
         owners who remained employed with Orius have not and will not change,
         and additional costs have not and are not expected to be incurred
         related to their efforts. Also reflects the elimination of compensation
         expense associated with the distribution of excess cash balances to the
         former owners of the Acquired Companies immediately prior to their
         dates of acquisition.

    (ii) Reflects the rent expense resulting from our current lease terms as
         compared to lease terms entered into by former owners. In addition,
         reflects the increase in rent expense and the corresponding decrease in
         real estate tax expense resulting from our leasing rather than owning
         certain related facilities which were not, and in the case of Irwin
         will not be, purchased from the former owners of the Acquired
         Companies.

(3) Depreciation has been derived utilizing the property, plant and equipment
    values of each of the Acquired Companies at the time of their acquisition,
    rather than utilizing values of property, plant and equipment actually held
    by each of the Acquired Companies in the period presented. Reflects the
    impact on depreciation resulting from (1) the application of Orius'
    depreciation policy rather than those of the former owners of the Acquired
    Companies and (2) any decrease in depreciation resulting from leasing rather
    than owning certain related facilities. In addition, reflects the change in
    depreciation resulting from the write-up of property, plant and equipment to
    fair value arising from purchase accounting.

    The acquisition adjustments to depreciation expense consist of the
    following:

                       SELECTED HISTORICAL FINANCIAL DATA

     In connection with the LISN acquisition, LISN's former stockholders
acquired control of Orius. As a result, LISN has been treated as the acquiring
corporation for accounting purposes even though it became a subsidiary of Orius
in the LISN acquisition. Therefore, LISN is our corporate predecessor for
accounting purposes and its historical financial statements are deemed to be our
historical financial statements.

     The following table presents historical financial data for LISN, Inc., as
of and for the six months ended June 30, 2000 and as of and for each of the
years ended December 31, 1995, 1996 and 1997. Results for the years ended
December 31, 1998 and 1999 represent the combined historical results for these
periods of LISN (which had no material operations prior to 1998) and LISN, Inc.
and the results of Orius for the period from December 15, 1999 through December
31, 1999. LISN and LISN, Inc., which were companies under common control, were
combined in a May 1999 recapitalization. Historical financial statements for
LISN (the name of which was ARION, Inc. prior to the recapitalization) are
included elsewhere in this prospectus.

     The selected historical financial data should be read in conjunction with
the information contained in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" "Certain Relationships and Related Party
Transactions" and the financial statements and related notes included elsewhere
in this prospectus.

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

OVERVIEW

     Of our pro forma revenues for the six months ended June 30, 1999,
approximately 59% was derived from External Telecom Services and 41% was derived
from Internal Telecom Services. Of these revenues, 60% was from services
provided to telecommunications services providers, 33% was from services
provided to broadband services providers and 7% was from services provided to
our commercial, governmental and other customers.

     Many of our contracts are awarded on the basis of competitive bids, the
final terms and pricing of which are frequently negotiated with the customer.
However, many of our contracts that are with customers with whom we enjoy a
long-standing business relationship are renegotiated prior to expiration without
competing bids. Generally, contracts for External Telecom Services provide that
we will furnish a specified unit of service for a specified unit price. For
example, we contract to install cable for a specified rate per foot. We
recognize revenue as the related work is performed. Production reports are
inspected and approved by both our on-site quality control manager and the
customer's on-site project manager. We also provide our External Telecom
Services through master service agreements, under which we provide all specified
services under a specified dollar amount within a defined geographic area, and
turnkey agreements, under which we provide comprehensive design, engineering,
installation and maintenance services.

     Our Internal Telecom Services contracts are provided on a
project-by-project basis, with revenue recognized on a percentage-of-completion
basis. Under this method, revenue is recognized on a cost-to-cost method based
on total cost incurred to date as a percentage of total estimated cost to
complete the contract. These projects generally require two to three months to
complete, with an average revenue of $20,000. We also provide our Network
Services under maintenance agreements, under which we agree to furnish a
specified unit of service for a specified price and bill our customers based on
the services performed.

     Project-specific agreements are billed on either a unit basis, as work is
completed, or a deferred unit or milestone basis, when work on a specified
segment of an entire project is completed. Unbilled revenues consist of
work-in-process on contracts based on work performed, but not yet billed. All
costs associated with unbilled revenues are recorded as expenses in the same
period as the unbilled revenue. Customers are generally billed weekly. This
process is intended to keep disputed billings to a minimum, improve receivable
collections and reduce our risk on deferred billing projects. Master service
agreements are billed on a unit basis with bills delivered upon completion of a
unit of work. Turnkey agreements are billed both on a unit and deferred unit or
milestone basis. We generally bill our Internal Telecom Services customers upon
job completion, with a lag of approximately two weeks between job completion and
billing.

     Direct costs include all direct costs of providing services to our
customers, other than depreciation on fixed assets that we own or use under
capital leases. We utilize subcontracted labor when the volume of our work
exceeds the capacity of our regularly employed labor force. By utilizing an
established pool of experienced subcontractors, we are able to capture
additional business which we would otherwise be unable to perform utilizing only
our in-house labor force. The benefit of the additional revenue generated
through the use of subcontracted labor is partially offset by the relatively
higher labor costs as compared to the cost of our internal work force. Materials
are typically provided by our External Telecom Services customers, other than in
connection with turnkey agreements, for which we supply materials. As part of
Internal Telecom Services, we supply accessory equipment, such as shelves, racks
and cable for use in the installation of central office equipment.

     General and administrative costs include all costs of our management
personnel and the management of our subsidiaries, rent, utilities, travel and
centralized costs such as insurance administration, professional costs and
clerical and administrative overhead. Our operating subsidiaries' senior
management, and, with

                                       46

respect to national accounts, our executive management, handle all sales and
marketing functions as part or their regular duties and, therefore, we do not
incur material selling expenses beyond that included under general and
administrative expenses.

ACQUISITIONS

     NATG's corporate predecessor, North American Tel-Com Group, was
incorporated in Florida in 1997. Parent was incorporated in Delaware in January
1999 and Orius Capital was formed in January 2000. As a result of a corporate
reorganization in February 1999, NATG became a subsidiary of Parent. We had no
substantive operations until March 1998.

     Beginning in March 1998, we acquired Cablemasters Corp., Channel
Communications, Inc., Excel Cable Construction, Inc. and Mich-Com Cable
Services, Incorporated. In June 1998, we acquired U.S. Cable, Inc., and in
August 1998, we acquired CATV Subscriber Services, Inc., Burn-Techs, Inc. and
State Wide CATV, Inc.

     In February 1999, we acquired DAS-CO of Idaho, Inc., Schatz Underground
Cable, Inc., Copenhagen Utilities & Construction, Inc. and Network Cabling
Services, Inc. In May 1999, we acquired Texel Corporation and in December 1999,
we acquired LISN. In January 2000, we acquired Irwin and in April 2000, we
acquired Fenix and Midwest Splicing. We acquired Hattech in May 2000.

     Our 18 completed acquisitions had pro forma 1999 revenues of approximately
$587.2 million. Prior to their acquisition by us, many of these companies were
operated with different strategic and financial objectives. Some of the former
owners of the businesses we acquired sought to maximize cash flow and
stockholder distributions, rather than reinvest earnings in future growth. In
addition, our acquired businesses operated under varying tax structures, which
influenced the historical level of owners' compensation. As a result of the
foregoing, direct costs and general and administrative expenses as a percentage
of revenue may not be comparable among the acquired businesses on a historical
basis.

     In connection with the LISN acquisition, LISN's former stockholders
acquired control of Parent. As a result, LISN has been treated as the acquiring
corporation for accounting purposes even though it became a subsidiary of NATG
in the LISN acquisition. Therefore, LISN is our corporate predecessor for
accounting purposes and its historical financial statements are deemed to be our
historical financial statements.

     The deemed acquisition of Parent by LISN and all of our previous
acquisitions were accounted for using the purchase method of accounting. As a
result, the historical financial statements of LISN and NATG, as the case may
be, do not include the results of operations of acquisitions prior to the date
they were acquired. The excess of the fair value of the consideration paid or to
be paid for the acquisitions, including LISN's deemed acquisition of Parent, of
$373.2 million over the fair value of the net assets so purchased has been
recorded as goodwill. The majority of this goodwill is being amortized over its
estimated useful life of 25 years as a non-cash charge to operating income. The
effect on our net income of these amortization expenses, a majority of which are
not deductible for tax purposes, is expected to be approximately $14.9 million
per year. As a result of the foregoing, we believe that the historical financial
statements of NATG and LISN included in this offering memorandum are not fully
reflective of the ongoing operations of the Company.

     We entered into a credit facility in connection with our February 1999
acquisitions and incurred a one-time non-cash related charge of approximately
$770,000, net of tax benefit of approximately $431,200, representing the
write-off of deferred financing costs. In connection with the refinancing of
this credit facility as part of the LISN Acquisition, we incurred a similar
non-cash charge of approximately $2.1 million net of tax benefit of
approximately $1.1 million, representing the write-off of deferred financing
costs.

     Since January of this year we have completed four acquisitions. In January
2000, we completed the acquisition of Irwin. Irwin is a Dallas, Texas based
provider of External Telecom Services to telecom

                                       47
<PAGE>   52

services providers in a variety of states. Irwin's primary customers include
AT&T Broadband & Internet Services, Charter Communications and Time Warner. In
April 2000, we completed the acquisitions of Fenix and Midwest Splicing. Fenix
and Midwest provide External Telecom Services to broadband service providers in
and around the Great Lakes region of the U.S. and the Midwest region of the
U.S., respectively. Fenix's primary customer is Charter Communications and
Midwest's primary customers include Media One and Paragon Cable. In May 2000 we
completed the acquisition of Hattech. Based in Chantilly, Virginia, Hattech
provides a wide range of network integration services to telecommunications
service providers and internet service providers. Hattech's primary customer is
AT&T.

     The aggregate purchase price for these acquisitions was approximately $74.2
million, consisting of approximately $60.7 million of cash, $12.2 million of
Parent's securities and the assumption of $1.3 million of debt. We funded $42.0
million of the cash purchase price with borrowings under our senior credit
facilities. These four companies had aggregate revenue and EBITDA for the year
ended December 31, 1999 of $78.8 million and $15.8 million, respectively.

RESULTS OF OPERATIONS

     HISTORICAL

     In connection with the LISN acquisition, LISN's former stockholders
acquired control of Parent. As a result, LISN has been treated as the acquiring
corporation for accounting purposes even though it became a subsidiary of NATG
in the LISN acquisition. Therefore, LISN is our corporate predecessor for
accounting purposes and its historical financial statements are deemed to be our
historical financial statements. The financial data referred to below for the
years ended December 31, 1998 and 1999 represent the combined historical results
for these periods of LISN (which had no material operations prior to 1998) and
LISN, Inc. for both periods, and of Orius for the period from December 15, 1999
through December 31, 1999. LISN and LISN, Inc., which were companies under
common control, were combined in a May 1999 recapitalization. Historical
financial statements for LISN (the name of which was ARION, Inc. prior to the
recapitalization) are included elsewhere in this prospectus. See "Selected
Historical Financial Data." The financial data for the year ended December 31,
1997 was derived from the audited financial statements of LISN, Inc., LISN's
largest predecessor company.

  Six Months Ended June 30, 2000 Compared to Six Months Ended June 30, 1999

     Revenue.  Revenue increased 481.2%, or $289.7 million, from $60.2 million
for the six months ended June 30, 1999 to $349.9 million for the six months
ended June 30, 2000. This increase in revenue was the result of the deemed
acquisition of Orius by LISN in December 1999. LISN's revenue, excluding the
revenues attributable to Orius, increased $52.1 million or 86.5%. The increase
in LISN's revenue was primarily due to increased revenue from EF&I Services
performed for Verizon, AT&T and Ameritech in both new and existing geographic
markets.

     Direct Costs.  Direct costs increased 523.6%, or $210.5 million, from $40.2
million for the six months ended June 30, 1999 to $250.7 million for the six
months ended June 30, 2000. Excluding the direct costs attributable to Orius,
LISN's direct costs increased $36.6 million, or 91.1%, and remained constant as
a percent of revenue. This increase was primarily due to additions to LISN's
labor force in response to an increased level of activity.

     General and Administrative Expenses.  General and administrative expenses
increased 162.7%, or $22.9 million, from $14.1 million for six months ended June
30, 1999 to $37.0 million for the six months ended June 30, 2000. Excluding the
general and administrative expenses attributable to Orius, LISN's general and
administrative expenses increased $0.7 million or 5.0%. Excluding Orius, these
amounts represent a 10.2% decrease in general and administrative expenses as a
percentage of revenue from 23.4% in 1999 to 13.2% in 2000. The increase in
general and administrative expenses was primarily due to the increase in
administrative staff and salaries resulting from LISN's increased activity.

                                       48
<PAGE>   53

     Depreciation and Amortization Expense.  Depreciation and amortization
expense increased $13.5 million, from $.3 million for the six months ended June
30, 1999 to $13.8 million for the six months ended June 30, 2000. This increase
in depreciation and amortization expense is the result of the inclusion of Orius
in the results for the six months ended June 30, 2000 and the inclusion of
amortization of goodwill from the LISN acquisition in our operating results.

     Interest Expense.  Interest expense increased $29.3 million, from $1.4
million for the six months ended June 30, 1999 to $30.7 million for the six
months ended June 30, 2000. This increase was due to higher levels of debt
incurred under our senior credit facilities in connection with the LISN
acquisition.

     Provision for Income Taxes.  The provision for income taxes increased 100%,
or $9.6 million, from $0.7 for the six months ended June 30, 1999 to $10.3
million for the six months ended June 30, 2000, reflecting an increase in the
effective tax rate of 58.5% for federal, state and local taxes for three months
ended March 31, 2000. This increase is the result of the change in LISN's status
from an S corporation to a C corporation in connection with the recapitalization
of LISN in May 1999. As an S corporation, LISN was generally not subject to
federal income tax at the corporate level.

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

     Revenue.  Revenue increased 119%, or $90.6 million, from $76.4 million for
the year ended December 31, 1998 to $167.0 million for the year ended December
31, 1999. This increase was due primarily from increased revenue from EF&I
Services performed for Bell Atlantic in both existing and new geographic
markets.

     Direct Costs. Direct costs increased 125%, or $65.9 million, from $52.7
million for the year ended December 31, 1998 to $118.5 million for the year
ended December 31, 1999. The increase was the result of an increase in our labor
force due to our increased level of activity, and represents a 2% increase in
direct costs as a percentage of revenue from 69% for the year ended December 31,
1998 to 71% for the year ended December 31, 1999. This increase is attributable
to an increased use of subcontractors necessary to achieve revenue growth and a
one-time bonus of $1.5 million paid to installers and engineers in connection
with the recapitalization of LISN in May 1999.

     General and Administrative Expenses. General and administrative expenses
increased 94%, or $9.9 million, from $10.6 million for the year ended December
31, 1998 to $20.5 million for the year ended December 31, 1999. The increase in
general and administrative expenses was due primarily to a one-time bonus of
$5.0 million paid to LISN's administrative employees in connection with the
recapitalization of LISN in May 1999. These amounts represent a 2.0% decrease in
general and administrative expenses as a percentage of revenue from 14% for the
year ended December 31, 1998 to 12% for the year ended December 31, 1999. This
decrease resulted from leveraging these expenses over an increased revenue base.

     Depreciation and Amortization Expense. Depreciation and amortization
expense was $0.4 for the year ended December 31, 1998 and $1.4 for the year
ended December 31, 1999. This increase was primarily due to the amortization of
$0.2 million of finance costs in connection with the recapitalization of LISN in
May 1999 and the amortization of $0.7 million in goodwill in connection with the
LISN acquisition.

     Interest Expense. Interest expense was $0.5 for the year ended December 31,
1998 and $10.5 million for the year ended December 31, 1999. This increase was
due to higher levels of debt incurred in connection with the recapitalization of
LISN in May 1999.

     Provision for Income Taxes. The provision for income taxes was $0.0 for the
year ended December 31, 1998 and $4.9 million for the year ended December 31,
1999, reflecting an effective tax rate of 31% for federal, state and local taxes
for the year ended December 31, 1999. This increase is the result of the change
in LISN's status from an S corporation to a C corporation in connection with the
recapitalization of LISN in May 1999. As an S corporation, LISN was generally
not subject to federal income tax at the corporate level.

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

     Revenue. Revenue increased 90.0%, or $36.2 million, from $40.2 million for
the year ended December 31, 1997 to $76.4 million for the year ended December
31, 1998. This increase was primarily due to increased revenue from EF&I
Services performed for Bell Atlantic, AT&T and Ameritech in existing and new
geographic markets.

     Direct Costs. Direct costs increased 78.0%, or $23.2 million, from $29.7
million for the year ended December 31, 1997 to $52.9 million for the year ended
December 31, 1998. The increase was the result of an increase in LISN's labor
force due to an increased level of activity, and represents a 4.7% decrease in
direct costs as a percentage of revenue from 73.9% for the year ended December
31, 1997 to 69.2% for the year ended December 31, 1998. This decrease was
attributable to the improved productivity of LISN's labor force.

     General and Administrative Expenses. General and administrative expenses
increased 76.3%, or $4.5 million, from $5.9 million for the year ended December
31, 1997 to $10.4 million for the year ended December 31, 1998. These amounts
represent a 1.1% decrease in general and administrative expenses as a percentage
of revenue from 14.7% for the year ended December 31, 1997 to 13.6% for the year
ended December 31, 1998. The increase in general and administrative expenses was
primarily due to increases in administrative staff and salaries, and accounted
for $3.0 million of the $4.5 million increase.

     Depreciation and Amortization Expense. Depreciation and amortization
expense was $179,000 for the year ended December 31, 1997 and $383,000 for the
year ended December 31, 1998.

     Interest Expense. Interest was $178,000 for the year ended December 31,
1997 and $450,000 for the year ended December 31, 1998.

  Pro Forma Six Months Ended June 30, 2000 Compared to Pro Forma Six Months
Ended June 30, 1999

     Revenue.  Revenue increased 47.2%, or $118.5 million, from $251.1 million
for the six months ended June 30, 1999 to $369.5 million for the six months
ended June 30, 2000. This growth was attributable in part to a 47.4% increase in
revenue from our External Telecom Services customers, which accounted for $70.7
million or 59.7% of the total increase. A milder than expected winter and
improved pricing arrangements on certain jobs contributed to the increase in
External Telecom Services revenue. Revenue from our Internal Telecom Services
customers increased 51.4%, which accounted for $52.4 million, or 44.3% of the
total increase. Included in that amount was a $52.3 million increase in revenue
from EF&I Services which increased 70.3% due primarily to an increase in
services provided to Verizon. Revenue from Network Services increased 0.7%, or
$0.1 million, due to a general increase in demand for our Network Services.

     Direct Costs.  Direct costs increased 44.8%, or $81.5 million, from $181.9
million for the six months ended June 30, 1999 to $263.3 million for the six
months ended June 30, 2000. The increase was the result of our increased level
of business activity. As a percent of revenue, direct costs decreased from 72.4%
for the six months ended June 30, 1999 to 71.3% for the six months ended June
30, 2000. Direct costs as a percent of revenue decreased most significantly with
respect to those broadband customers for whom we provide External Telecom
Services. In the first half of 1999, several of our subsidiaries recorded
significant expenses relating to project accounting and accounts receivable.
Similar expenses did not need to be recorded during the first half of 2000, as
we have put in place more effective quality control procedures relating to
collections and lingering project costs. Improved pricing on certain projects
for our broadband customers contributed to the decrease in direct costs as a
percent of revenue.

     General and Administrative Expenses.  General and administrative expenses
increased 53.9%, or $14.7 million, from $27.2 million for the six months ended
June 30, 1999 to $41.9 million for the six months ended June 30, 2000. The
increase was due to increased payroll and other expenses resulting from our
growth. As a percent of revenue, the level of general and administrative
expenses increased from 10.8% for the six months ended June 30, 1999 to 11.3%
for the six months ended June 30, 2000. Management expects to be able to
maintain this level of general and administrative expenses as a percent of
revenue throughout 2000.

     Depreciation and Amortization Expense.  Depreciation and amortization
expense was $8.0 million for the six months ended June 30, 1999 and $14.5
million for the six months ended June 30, 2000.

     Interest Expense.  Interest expense,net, was $32.6 million for the six
months ended June 30, 1999 and $32.6 million for the six months ended June 30,
2000. We expect that our interest expense will increase in 2000 over 1999 levels
due to the utilization of the $100.0 million in borrowing capacity under the
senior credit facilities, which is available for working capital and
acquisitions.

     Provision for Income Taxes.  Provision for income taxes increased $2.0
million to $7.3 million for the six months ended June 30, 2000. Our effective
tax rate increased from 22.8% for the six months ended June 30, 1999 to 42.2%
for the six months ended June 30, 2000. Our effective tax rate is affected by
the non-deductibility of $6.3 million of goodwill attributable to acquisitions,
which will cause us to experience a significantly higher effective tax rate than
statutory levels for the foreseeable future.

  Pro Forma Year Ended December 31, 1999 Compared to Pro Forma Year Ended
  December 31, 1998


     Revenue. Revenue increased 50.3%, or $196.6 million, from $390.6 million
for the year ended December 31, 1998 to $587.2 million for the year ended
December 31, 1999. This growth was attributable in part to a 45% increase in
revenue from our External Telecom Services customers, which accounted for $107.2
million, or 59%, of the total increase. Favorable weather conditions at key
external telecom project sites and a general increase in demand for our External
Telecom Services contributed to this increase. Revenue from our Internal Telecom
Services customers increased 57%, which accounted for $89.4 million, or 41%, of
the total increase. Included in that amount was a $69.0 million increase in
revenue for EF&I Services, primarily performed for Verizon, which accounted for
38% of the total increase. Revenue from Network Services grew 10% over the
comparable period, or $5.5 million, due to a general increase in demand for our
Network Services.


     Direct Costs. Direct costs increased 49.9%, or $139.6 million, from $279.5
million for the year ended December 31, 1998 to $419.1 million for the year
ended December 31, 1999. The increase was the result of an increase in our level
of activity. As a percentage of revenue, direct costs remained flat from the
year ended December 31, 1998 to the year ended December 31, 1999.

     General and Administrative Expenses. General and administrative expenses
increased 38.4%, or $17.6 million, from $45.8 million for the year ended
December 31, 1998 to $63.4 for the year ended December 31, 1999. The increase in
general and administrative expenses was due to increased payroll and other
expenses required to service our increased level of activity. These amounts
represent a 0.9% decrease in general and administrative expenses as a percentage
of revenue from 11.7% for the year ended December 31, 1998 to 10.8% for the year
ended December 31, 1999. This decrease resulted from leveraging these expenses
over an increased revenue base. We expect to be able to maintain this level of
general and administrative expenses as a percentage of revenue for the year
ending December 31, 2000.

     Depreciation and Amortization Expense. Depreciation and amortization
expense was $23.1 million for the year ended December 31, 1998 and $26.8 million
for the year ended December 31, 1999.

     Interest Expense. Interest expense, net, was $64.8 million for the year
ended December 31, 1998 and $64.8 million for the year ended December 31, 1999.
We expect that our interest expense will increase in 2000 over 1999 levels due
to the utilization of the $100.0 million in borrowing capacity under the senior
credit facilities, which is available for working capital and acquisitions.

     Provision for Income Taxes. The provision for income taxes increased $13.3
million, from a benefit of $2.3 million for the year ended December 31, 1998 to
an expense of $11.0 million for the year ended December 31, 1999. Our effective
tax rate is affected by the non-deductibility of $9.6 million of goodwill in
each period attributable to acquisitions, which will cause us to experience a
significantly higher effective tax rate than statutory levels for the
foreseeable future.

LIQUIDITY AND CAPITAL RESOURCES


     In connection with the LISN acquisition, we entered into the senior credit
facilities. The senior credit facilities were amended and restated on July 5,
2000 to provide for the tranche C term loan. The senior credit facilities
provide for aggregate borrowings of up to $435.0 million, consisting of the
following:


     - $100.0 million revolving credit facility to be used for permitted
       acquisitions and for working capital purposes, with sublimits of $75.0
       million for acquisition loans and $50.0 million for working capital loans
       and a maximum of $100.0 million in borrowings at any one time;

     - $75.0 million tranche A term loan with a $50.0 million letter of credit
       subfacility;

     - $200.0 million tranche B term loan; and

     - $60.0 million tranche C term loan.

     Working capital loans borrowed under the revolving credit facility can only
be used for working capital purposes, capital expenditures and other general
corporate purposes. Acquisition loans borrowed

                                       52
<PAGE>   57

under the revolving credit facility may only be used to finance a limited number
of acquisitions that are otherwise permitted by the terms of the senior credit
facilities. To the extent that the amount borrowed for acquisition loans exceeds
$50.0 million, the amount available for working capital loans is reduced dollar
for dollar.

     As of July 5, 2000, there was $288.6 million of outstanding indebtedness
under the senior credit facilities (excluding $5.7 million of letters of credit
and $7.2 million of standby letters of credit), $50.0 million available under
the revolving credit facility for working capital and other corporate purposes
and $75.0 million available for acquisitions, although no more than $100.0
million in the aggregate may be borrowed under the revolving credit facility.

     The proceeds of the tranche A and tranche B term loans were used to finance
the LISN acquisition and, except as described below, were fully drawn down at
the closing of the LISN acquisition and may not be reborrowed. The proceeds of
the tranche C term loan were used to repay loans outstanding under the revolving
credit facility and may not be reborrowed. Our obligation to certain of our
stockholders in connection with the put and call agreements entered into in
connection with the LISN acquisition are supported by $46.5 million of letters
of credit issued under the tranche A term loan letter of credit subfacility.
These letters of credit will be drawn to fully fund the amounts payable upon the
exercise of our call options. As of March 31, 2000, we had drawn $40.8 under
these letters of credit. In addition, a total of $7.2 million of standby letters
of credit have been issued under the revolving credit facility. These standby
letters of credit will expire in accordance with their terms without being drawn
when we exercise our call options.

     As of July 5, 2000, rates on borrowings under the senior credit facilities
ranged from 9.6% to 10.3%. Borrowings of working capital under the revolving
credit facility are due December 15, 2004 and may be borrowed, repaid and
reborrowed prior to maturity. Until December 15, 2001, acquisition loans under
the revolving credit facility may be borrowed, repaid and reborrowed. On
December 15, 2001, any acquisition loans outstanding will be converted into an
amortizing term loan, payable quarterly, with 20% of the loan payable in 2002,
25% of the loan payable in 2003 and 55% of the loan payable in 2004, with the
final payment due December 15, 2004. Borrowings under the tranche A term loan
are due December 15, 2004, borrowings under the tranche B term loan are due
December 15, 2006 and borrowings under the tranche C term loan are due December
15, 2007. The tranche A, tranche B and tranche C term loans are payable
quarterly in arrears.

     Our senior credit facilities and the indenture governing the notes contain
numerous restrictive covenants, including, among other things, covenants that
limit the issuers' ability to borrow money, make capital expenditures, use
assets as security in other transactions, pay dividends, incur contingent
obligations, sell assets and enter into leases and transactions with affiliates.
In addition, the senior credit facilities require us to meet specified financial
ratios and tests. In the event that we fail to comply with the various covenants
contained in our senior credit facilities, we would be in default under our
senior credit facilities and the maturity of substantially all of our long-term
indebtedness could be accelerated. All borrowings under the senior credit
facilities are guaranteed by, and are secured by substantially all of the assets
of, Parent and all of our present and future domestic subsidiaries.

     We used approximately $43.2 million of the proceeds from the offering of
the outstanding notes to repay $42.6 in aggregate principal amount of the
tranche B term loan. Under the terms of the senior credit facilities, we were
required to repay this amount at 101% of the principal amount. We used
approximately $102.0 million of the proceeds of the offering of the notes to
repay our $100.0 senior subordinated term loan, plus accrued interest, that was
used to fund a portion of the LISN acquisition. We used approximately $57.0
million of the proceeds of the tranche C term loan to repay loans outstanding
under the revolving credit facility and the remainder for related fees and
expenses.

     We expect that our principal sources of liquidity will be from cash flow
generated from operations and borrowings under the senior credit facilities. We
believe that these funds will be sufficient to meet our needs for the next
twelve months. Our principal uses of liquidity will be to meet our debt service

                                       53
<PAGE>   58

obligations, provide working capital availability, finance our capital
expenditures and partially fund future acquisitions.

     The combined capital expenditures of NATG and LISN for 1999 were
approximately $13.0 million. Our capital expenditures for 1999 included an
upgrade to our management information system and for additions to vehicles and
equipment of approximately $8.9 million and a $1.2 million expansion of LISN's
Amherst, Ohio corporate offices, including a $420,000 land purchase. We
anticipate that our capital expenditures in 2000 will be approximately $16.0
million.

     The majority of our working capital requirements are attributable to billed
and unbilled accounts receivable. As of December 31, 1999, on a pro forma basis,
our billed days sales outstanding were 76 days and our unbilled days sales
outstanding were 14 days. We believe our days sales outstanding for billed and
unbilled receivables are generally in-line with the industry average and
generally reflect the payment policies of telecom services providers. Our
accounts receivable balance has increased due to the increased utilization of
milestone billing by our customers. With milestone billing, a customer will only
accept a bill upon completion of a discrete portion of a project, without regard
to the time it takes for the portion to be completed. The milestone billing
terms for our large turnkey projects, which represent 14% of the balance of our
receivables, have been a significant contributor to our balance of receivables
days sales outstanding. We have taken proactive steps to try to reduce our
unbilled accounts receivable balance and have been successful in negotiating
pre-payments with respect to our turnkey contracts to alleviate the burden on
our working capital.

     As part of our growth strategy, we intend to pursue selective acquisitions.
We cannot predict the timing, size or success of any prospective acquisitions
and the related capital commitments. To the extent that we seek to grow by
acquisitions that involve consideration other than Parent's securities, our
capital requirements may increase. We expect to fund future acquisitions
primarily with issuances of additional Parent securities, the available portion
of our acquisition facility and cash flow from operations.

     As of June 30, 2000, we had $0 cash and cash equivalents, working capital
of $66.0 million, short-term debt of $69.0 million and long-term debt, net of
current maturities of $521.9 million.

     During the six months ended June 30, 2000, operating activities provided
$1.8 million of net cash primarily due to growth in our revenue. We used $72.7
million in cash in investing activities, which included $14.2 million for
capital expenditures and $58.5 million for acquisitions. Financing activities
provided cash of $42.2 million, resulting primarily from proceeds from the
issuance of the outstanding notes and from borrowings under the senior credit
facilities offset by payments in connection with put/call arrangements and
repayment of debt.

     During the year ended December 31, 1999, operating activities provided
$13.8 million. We used net cash in investing activities of $170.2 million,
including $166.1 million relating to the LISN acquisition. Financing activities
provided a net cash flow of $182.3 million, resulting primarily from borrowings
under the senior credit facilities.


     Parent intends to file a registration statement with the SEC relating to a
proposed initial public offering of shares of its common stock with an estimated
aggregate value of $250 million. We expect that the offering will be completed
in the fourth quarter of 2000. The proceeds of the offering to be received by
Parent are expected to be used to repay a portion of the indebtedness under the
senior credit facility, to prepay a portion of the notes, to prepay a portion of
Parent's junior subordinated notes and for general corporate purposes. We cannot
assure you that the offering will be completed or, if completed, that it will be
on the terms outlined above. The offering will be made pursuant to an effective
registration statement and this prospectus shall not be deemed to be an offer to
sell our common stock.


SEASONALITY; FLUCTUATIONS OF QUARTERLY RESULTS

     Our operations are seasonal, generally resulting in reduced revenues and
profits during the first and fourth quarters relative to other quarters. Factors
affecting the seasonality of our business are holiday

                                       54
<PAGE>   59

season shut-downs, adverse weather conditions and year-end budgetary spending
patterns of our customers. These factors can negatively affect telecom systems
repair, replacement and expansion. Additionally, our industry can be highly
cyclical. As a result, our business volume may be adversely affected by declines
in new projects in various geographic regions. Quarterly results may also be
materially affected by the timing and magnitude of acquisitions and related
costs, variations in the margins of projects performed during any particular
quarter, the timing and volume of work under new agreements, customer spending
patterns, termination of existing agreements, costs incurred in connection with
internal growth, changes in our mix of customers, contracts or business,
fluctuations in construction and design costs, and regional and general economic
conditions. Accordingly, our operating results in any particular quarter may not
be indicative of the results that can be expected for any other quarter or for
the entire year.

MARKET RISK

     Market risk is the potential loss arising from adverse changes in market
rates and prices, such as foreign currency exchange and interest rates. Although
we are not subject to material foreign currency exchange risk, we are exposed to
changes in interest rates. All of our debt, other than the notes, is variable
rate debt. Interest rate changes generally do not affect the fair market value
of variable rate debt but do impact future earnings and cash flows, assuming
other factors are held constant. Conversely, for fixed rate debt, interest
changes do not impact future cash flow and earnings, but do impact the fair
market value of fixed rate debt, assuming other factors are held constant. At
June 30, 2000, we had variable rate debt of approximately $285.8 million and
fixed rate debt of approximately $150.0 million. Holding other variables
constant (such as debt levels) a one percentage point increase in interest rates
would have had an estimated impact on pre-tax earnings and cash flows for next
year of approximately $2.6 million. In order to manage our interest rate risk,
we have entered into interest rate cap agreements and swaps with a notional
amount of $118.0 million as of June 30, 2000. These agreements limit, but do not

     In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This Statement is effective for our 2001
financial statements. This Statement requires that entities recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. Due to the complexity of
this Statement, we are still evaluating the impact, if any, on our financial
statements.

     In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition" (SAB 101), which affects the recognition and disclosures
about revenues. SAB 101 is applicable for our fourth quarter 2000 financial
statements. We do not expect the adoption of SAB 101 to have a significant
impact on our financial statements.

                                    BUSINESS

INTRODUCTION

     We believe that we are one of the largest independent providers of
comprehensive telecom infrastructure services in the U.S., with operations in 48
states. We offer a full spectrum of services, including:

     - External Telecom Services -- installation, design, engineering and
       maintenance of fiber optic, coaxial and copper cable networks for the
       telecom industry; and

     - Internal Telecom Services -- engineering, furnishing and installation of
       network equipment and related components and related maintenance
       services, primarily in the central offices of telecommunications services
       providers, which we refer to as "EF&I Services," and similar network
       services for commercial, governmental and institutional entities, which
       we refer to as "Network Services."

     We believe that our ability to provide comprehensive, quality service on a
nationwide basis positions us as a leading, full-service provider of telecom
infrastructure services to the telecom industry. For the six months ended June
30, 2000, we had pro forma revenue of $369.5 million and pro forma EBITDA of
$64.3 million. For the year ended December 31, 1999, we had pro forma revenue of
$587.2 million and pro forma EBITDA of $104.6 million.

     Our 1999 pro forma revenue was derived 59% from External Telecom Services
and 41% from Internal Telecom Services. More than 80% of our 1999 pro forma
revenue was generated from repeat customers, often under turnkey agreements,
master service agreements and preferred provider arrangements. Our principal
customers include providers of telecommunications services, such as Ameritech,
AT&T, Bell Atlantic, DTI, GTE, MCI WorldCom, Verizon and Williams
Communications, and providers of broadband services, such as Adelphia, AT&T
Broadband & Internet Services, Charter Communications, Clearsource, Comcast, Cox
Communications, Digital Access and Universal Access. We also provide our Network
Services for customers such as Compaq, Dell, EDS and World Bank.

     The LISN acquisition provided us with access to the significant and rapidly
growing central office EF&I Services market. As a result of this acquisition, we
believe that we are the largest independent provider of EF&I Services to the
telecom industry in the U.S. We design configurations for a broad range of
equipment installations using our engineering capabilities, implement the
designs with our extensive installation expertise and furnish our customers with
a variety of accessory equipment such as racking materials, wire and cables.

INDUSTRY TRENDS

     Market data used throughout this prospectus are based on our internal
estimates and from industry publications, including reports generated by the
Multimedia Telecommunications Association, World Information Technologies, Inc.
and Dataquest. Neither we nor any of our affiliates requested that these reports
be prepared, nor have we independently verified these reports. These
organizations have not consented to the inclusion of data from their reports in
our prospectus, nor have we sought their consent. Similarly, our internal
estimates, while we believe them to be reliable, have not been verified by an
independent source.

     We estimate that the market for telecom infrastructure services exceeded
$40 billion in 1998 and that the market possesses positive growth dynamics. The
MultiMedia Telecommunications Association estimates that telecommunications and
broadband services providers spent over $19 billion on telecom infrastructure
services in 1998 and projects expenditures will grow at a compound annual rate
of approximately 14% through 2002. According to World Information Technologies,
Inc., expenditures for EF&I Services accounted for approximately $5 billion of
the total telecom infrastructure services expenditures by telecommunications and
broadband services providers in 1998, and are projected to grow at a compound
annual rate of approximately 41% through 2002. Expenditures for Network Services
by

                                       56
<PAGE>   61

commercial, governmental and institutional entities are estimated by Dataquest
to have exceeded $20 billion in 1998 and are estimated by Dataquest to grow at a
compound annual rate of approximately 18% through 2002.

     We believe that our industry presents substantial growth opportunities for
large companies like us with significant capital resources, broad geographic
coverage, comprehensive technical capabilities and the ability to provide
responsive, high quality service on a consistent basis. Growth in our industry
has been driven by the following trends:

     - Telecom Deregulation. The Telecommunications Act of 1996 substantially
       revised prior law by preempting state and local government control over
       access to the telecommunications and cable television market. The
       Telecommunications Act eliminated regulatory barriers to competition such
       as the antitrust consent decree that had restricted the Regional Bell
       Operating Companies from offering long distance telephone service, many
       federal pricing regulations that had affected cable television providers
       and FCC restrictions that had prevented telephone companies from offering
       cable television services. In response to these changes, existing and
       newly created companies have raced to install new networks and upgrade
       existing networks to enter new markets to maintain or gain market share.
       The Telecommunications Act also required that competitive local exchange
       carriers be granted access to existing central offices of incumbent local
       exchange carriers, a practice known as co-location, which requires
       rewiring of the switches and has significantly increased demand for EF&I
       Services. We believe the elimination of these entry barriers has
       increased and will continue to increase competition among telecom
       services providers and drive additional investment in telecommunications
       network infrastructure. In addition, many state regulatory commissions
       have eliminated pricing regulations for telecom providers, thus requiring
       these providers to become efficient in installing and maintaining their
       telecom and cable television networks so as to be price competitive. As a
       result, providers are entering new markets, offering services that once
       were reserved for incumbent providers, and expanding and improving their
       existing networks.

     - Increased Voice, Video and Data Traffic on Telecom Networks. Growth in
       demand for Internet services, telecommunications voice and data traffic,
       electronic commerce, delivery of information and entertainment services,
       and the growth, use and reliance on personal computers has created an
       increased need for greater bandwidth. Bandwidth refers to both the speed
       and breadth of voice, video and data communications. Bandwidth is limited
       by the size and the physical and technological characteristics of the
       cable, equipment or other facilities through which communications flow.
       Because of the physical limitations of existing network facilities,
       telecom services providers are upgrading facilities with new and
       innovative technology, expanding and, in many cases, replacing existing
       telecom infrastructure to allow for increased bandwidth in order to offer
       faster and greater volume of communications flow.

     - Increased Outsourcing. The level of outsourcing by telecom services
       providers is expected to continue to increase due to the need of these
       service providers to upgrade and expand their networks as a result of
       increased competition. The outsourcing trend has largely been driven by
       the efforts of telecom services providers to expedite the expansion,
       maintenance, replacement and enhancement of their networks, to reduce
       costs and to focus on their core competencies. Companies that specialize
       in providing telecom infrastructure services to the telecom industry are
       generally able to provide these services on a lower cost basis. In
       addition, we believe that telecom services providers are seeking to
       reduce the number of their telecom infrastructure services providers, and
       thereby the administrative expense and managerial burden of managing
       their services providers, by establishing preferred relationships with a
       select number of services providers that are able to consistently offer
       comprehensive solutions to their network needs across a broad geographic
       area.

     - Customer Consolidation. While deregulation has created new market
       participants, consolidation in the telecom industry has created
       geographically diverse and in some cases integrated providers. The
       expansion of the geographic markets served by telecom services providers
       has increased the

                                       57
<PAGE>   62

requirement for telecom infrastructure services providers to have broad
geographic coverage capabilities. As the size and scope of telecom services
providers have expanded, they are increasingly requiring telecom infrastructure
      services providers to provide installation, design, engineering, and
      maintenance services simultaneously over multiple geographic regions. Many
      of the smaller regional and local companies in our industry do not have
      the financial resources or personnel necessary to provide comprehensive
      service capabilities over a broad geographic area or the ability to manage
      multiple projects.

     - Emergence of Preferred Service Providers. We believe that telecom
       services providers increasingly prefer to simplify vendor management
       through the use of telecom infrastructure service providers with
       significant capital resources, broad geographic coverage, comprehensive
       technical capabilities and the ability to provide responsive, quality
       service on a consistent basis. Telecom infrastructure services providers
       must be able to rapidly mobilize their capital equipment, financial
       assets and personnel resources to effectively respond to the increasing
       scale and time constraints of customer demands. As telecom services
       providers expand their geographic market, we believe they often desire to
       extend existing relationships with their existing telecom infrastructure
       service providers to these new markets and are increasing the use of
       turnkey and master service agreements. Turnkey agreements typically
       require the telecom infrastructure service provider to install, design,
       engineer and often maintain a comprehensive network for a specific
       project. Master service agreements typically require the telecom
       infrastructure service provider to install, design and maintain systems
       and equipment for a variety of projects over a three to five year period
       in a specified geographic area. Telecom infrastructure services providers
       must be able to support the substantial initial working capital and
       equipment commitments required for these turnkey and master service
       agreements. This trend favors large services providers like us with
       significant capital resources over smaller industry competitors.

COMPETITIVE STRENGTHS

     We believe that we possess a number of competitive strengths that position
us as a leading provider of telecom infrastructure services and provide us with
the ability to meet the increased demand for these services and to take
advantage of the strong technology-driven growth occurring in the telecom
industry, including:

     - Comprehensive Service Capabilities. We believe that we are one of the few
       service providers with the capability to offer our customers integrated
       and comprehensive telecom infrastructure services, including
       installation, design, engineering, furnishing and maintenance services.
       This capability is important to our customers, who increasingly prefer to
       simplify their vendor management through the use of fewer preferred
       service providers who can offer comprehensive solutions to their telecom
       infrastructure needs. In addition, we believe our comprehensive service
       capabilities across nearly all competing telecom infrastructure
       technologies minimizes our risk of technological obsolescence.


     - Broad Geographic Coverage. Consolidation in the telecom industry has
       created geographically diverse telecom services providers who require
       telecom infrastructure services providers with similarly broad
       geographical capabilities. The telecom infrastructure services industry
       is highly fragmented, with the seven largest public companies, together
       with Orius, accounting for less than 6% of estimated total industry
       revenues in 1999, and includes hundreds of significantly smaller local
       and regional companies that can only offer their services over a limited
       geographic area. We believe that our ability to provide our services to
       customers on a nationwide basis positions us to be a preferred service
       provider to our customers and provides us with a competitive advantage
       over local and regional companies in our industry. We have significantly
       broadened our geographic presence in the past two years through strategic
       acquisitions, including our acquisition of LISN, and currently have
       operations in 47 states.


     - Strong Customer Relationships. More than 80% of our 1999 pro forma
       revenue was derived from repeat customers. Through our operating
       subsidiaries, we have enjoyed business relationships with

                                       58
<PAGE>   63

       many of our larger customers for more than 20 years. In addition, we are
       a preferred service provider to a number of these customers. As a result
       of our strong customer relationships, we are well positioned to
       capitalize on the increasing trend of telecom services providers towards
       greater outsourcing of their telecom infrastructure needs.

     - Reputation and Commitment to Quality. We believe that we have a
       reputation in our industry for responsive, high quality service, as
       evidenced by LISN's receipt of customer service awards, including
       Siemens' "1998 Contractor of the Year" and GTE's "Supplier Recognition
       Award" in 1997. Our commitment to quality is further evidenced by LISN's
       achievement in September 1998 and continued renewal of ISO 9002
       certification.

     - Decentralized Operating Strategy. We manage our operations on a
       decentralized basis while maintaining overall operating and financial
       controls and strategic planning at our corporate headquarters. Our
       operating subsidiaries have been in business for an average of more than
       20 years and retain responsibility for the operations, profitability and
       growth of their individual businesses. We believe that our decentralized
       operating structure retains the entrepreneurial spirit of each of the
       businesses we acquire and permits us to capitalize on the acquired
       businesses' customer relationships, local and regional market knowledge,
       local brand name recognition and specialized skills. At the same time,
       our management team coordinates overall marketing strategies to maximize
       the utilization of our resources and reviews operations at our
       subsidiaries to identify those practices that can be implemented
       successfully throughout our operations.

     - Experienced Management. Our executive management and the senior
       management of our operating subsidiaries have an average of over 20 years
       of experience in the telecom infrastructure services industry and our
       chief executive officer, William J. Mercurio, has more than 25 years of
       experience in this industry. Our executive management team also has
       substantial acquisition experience, having completed 18 acquisitions
       since 1998, including the LISN Acquisition. In addition, we have
       generally retained key personnel from acquired companies, which has
       enabled us to strengthen our management team. We also benefit from the
       considerable financial, management and acquisition experience of our
       largest stockholder, Willis Stein & Partners, a leading private equity
       investment firm based in Chicago, Illinois with more than $1.2 billion of
       assets under management as of December 31, 1999.

BUSINESS STRATEGY

     Our objective is to enhance what we believe is our position as one of the
largest independent providers of comprehensive telecom infrastructure services
in the U.S. We seek to utilize our competitive strengths to take advantage of
substantial growth opportunities in the telecom industry that favor large
companies like us with significant capital resources. Key elements of our growth
and operating strategies include the following:

     - Continue to Grow Internally. We believe we can continue to achieve
       internal growth by:

             Continuing to Develop National Service Capabilities. To meet our
        customers' increasing preference for service providers who can provide
        telecom infrastructure services on a nationwide basis, we have expanded
        our business to include operations in 48 states. Continued expansion
        into markets in which we do not currently have a significant presence is
        fundamental to our strategy of enhancing what we believe is our position
        as one of the largest providers of comprehensive telecom infrastructure
        services in the U.S. Part of this strategy involves securing large,
        long-term contracts in new geographic markets that provide us with the
        local presence necessary to capture business from other potential
        customers in these markets.

             Focusing on Cross-Selling Opportunities. Our comprehensive service
        offerings and broad geographic coverage provide us with the opportunity
        to expand our service offerings across our customer base. For example,
        we believe that our strong relationships with our External Telecom
        Services customers located in the Southwestern and Western regions of
        the U.S. provide us with

                                       59
<PAGE>   64

        the opportunity to expand our EF&I Services in these regions. Similarly,
        our strong relationships with our EF&I Services customers in the
        Northeastern and Mid-Atlantic regions of the U.S. provide us with the
        opportunity to expand our External Telecom Services in that region.

             Maximizing Performance of Existing Operations. We have been able to
        increase internal growth by enhancing the performance of the businesses
        we have acquired through the integration of their resources with our
        existing operations. Although our operating subsidiaries retain
        responsibility for the operations, profitability and growth of their
        individual businesses, our executive management team has responsibility
        for overall operations, financing, capital expenditures, corporate
        strategy, acquisitions and the coordination of overall marketing and
        bidding strategies to maximize the utilization of our resources. By
        combining overlapping operations of the businesses we have acquired, we
        have achieved, and believe we can continue to achieve, more efficient
        asset and personnel utilization and reductions in incremental overhead
        and general and administrative expenses. As we grow internally and
        acquire additional businesses, we will seek to realize additional cost
        savings and other benefits through shared purchasing, bidding,
        scheduling and the establishment of best practices.

             Expanding Our Service Offerings. We believe that opportunities
        exist to grow internally by expanding the services we offer. We are
        targeting new services that are complementary to the services we
        currently offer, such as installing telecommunications software,
        installing and maintaining wireless networks and providing testing,
        turn-up, monitoring and dispatch repair and maintenance services. We
        believe that opportunities also exist in the Internal Telecom Services
        market to generate additional revenue by providing our current services
        for a broader set of manufacturers' products. In addition, we are
        expanding our design and engineering services, which are in particularly
        high demand by telecom services providers. The expansion of our design
        and engineering services can provide us with both an increased revenue
        stream and the opportunity to exert greater control over project flow
        and specifications, which in turn can provide us with a competitive
        advantage in bidding for the related installation and maintenance work.

     - Selectively Pursuing Strategic Acquisitions. We plan to continue to
       pursue strategic acquisitions in the fragmented telecom infrastructure
       services industry. We have acquired 18 companies since March 1998,
       including our acquisition of LISN, and have gained significant experience
       in identifying, purchasing and integrating telecom infrastructure
       businesses.

     - Attract, Train and Retain Highly Qualified Personnel. We focus on
       attracting and retaining a highly trained and motivated workforce in
       order to consistently deliver innovative customer solutions and
       high-quality service. Our strategy is to become the employer of choice in
       each of the markets in which we operate by offering our employees
       comprehensive ongoing internal technical and managerial training programs
       throughout their careers, competitive compensation and employee benefits,
       career development opportunities, geographic mobility and equity
       participation in our success.

TELECOM INFRASTRUCTURE SERVICES

     EXTERNAL TELECOM SERVICES

     Design and Engineering. We offer a variety of design and engineering
capabilities as part of our External Telecom Services. We design aerial, buried
and underground fiber optic, coaxial and copper cable systems for all segments
of our customers' network infrastructure. Our engineering services include the
design of service area concept boxes, terminals, buried and aerial drops and the
proper administration of feeder and distribution cable pairs. For competitive
access providers, we design building entrance laterals, fiber rings and conduit
systems. We obtain rights of way and permits in support of engineering
activities, and provide installation management and inspection personnel in
conjunction with engineering services or on a stand-alone basis. In addition,
for broadband services providers we perform make ready studies, strand

                                       60
<PAGE>   65

mapping, field walk out, computer-aided radio frequency design and drafting, and
fiber optic cable routing and design.

     Installation and Maintenance. We provide a full range of installation and
maintenance services to our customers. The services we provide include the
splicing and placing of cable, excavation of trenches in which to place the
cable, placement of related structures such as poles, anchors, conduits,
manholes, cabinets and closures, placement of drop cable from the main
distribution lines to the customer's home and businesses, and maintenance and
removal of these facilities. We have the capacity to directionally bore the
placement of cables, a highly specialized and increasingly necessary method of
placing buried cable networks in congested urban and suburban markets where
trenching is highly impractical due to the disruptive effect of trenching on the
surrounding area. We also employ a licensed rail plow device which enables us to
bury cable on railway easements expeditiously at a low cost.

     INTERNAL TELECOM SERVICES

     EF&I Services

     Engineering. We engineer design configurations for a broad range of
equipment installations, ranging from low-end frame relays, which serve as an
interface between user and network equipment, to advanced broadband digital
cross-connect systems and digital subscriber lines, or DSLs, and platforms,
which enable high speed data and video transmission. Our engineers create
computer-generated schematic drawings that are tailored to each specific
installation project. All drawings are verified for accuracy with the central
office records through site surveys or on-line database checks. Our engineers
develop creative solutions to installation and upgrade projects for central
office switching, transmission and power systems. Our engineers work closely
with customers' engineers to develop detailed installation instructions and
drawings to ensure that the installation process is performed efficiently and
correctly.

     Equipment Furnishing. We provide accessory equipment such as shelves, racks
and cable for use in the installation of central office equipment. This service
ensures an availability of supplies and enables us to meet accelerated
installation timetables. Our furnishing operations provide us with a significant
competitive advantage as a result of our ability to ship equipment on a
just-in-time basis in 24 hours or less and to pre-pack materials specific to a
given job site on a lower cost basis.

     Installation. Our team of over 1,200 installation technicians has extensive
experience installing a full range of central office equipment, including
asynchronous and synchronous optical network multiplexers, T1 repeaters, digital
loop carrier systems, data bridges, network monitoring devices, alarming
systems, routers, power equipment, DSL and other equipment. Prior to beginning
installation, the installation technician reviews engineering drawings and
checks job site materials against specifications. The responsibilities of the
installation team include taking inventory of equipment, mounting, cabling and
wiring to schematics, performing functional equipment tests, integrating new
equipment with the existing exchange, and updating all specifications and
drawings. The installation team tests the system prior to reporting a completed
package to engineering in order to ensure that the equipment functions properly.

  Network Services

     We provide a variety of interior wiring services which include the
installation, design, engineering and maintenance of communications networks in
commercial, institutional and governmental facilities. These services generally
include the establishment and maintenance of computer operations, telephone
systems, local area networks and wide area networks, Internet access and systems
for monitoring environmental controls or security procedures.

ACQUISITION PROGRAM

     Since our formation in August 1997, we have acquired 18 telecom
infrastructure services providers. These companies had pro forma revenues for
the twelve months ended December 31, 1999 of

                                       61
<PAGE>   66

approximately $587.2 million. For a list of the businesses we have acquired, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Acquisitions."

     We believe that we are regarded by acquisition candidates as an attractive
acquirer because of the following factors:

     - our strategy for creating a nationwide comprehensive and professionally
       managed business servicing the telecom industry,

     - opportunities to participate in a larger organization with greater access
       to capital resources,

     - our decentralized operating strategy which retains the entrepreneurial
       spirit of the acquired businesses by allowing acquired companies to
       retain responsibility for their own individual operations, profitability
       and growth,

     - our potential for increased profitability due to centralized
       administrative functions, enhanced management information systems and
       economies of scale, and

     - the potential for owners of the businesses being acquired to realize some
       liquidity, while continuing to participate in our planned growth through
       continued equity ownership in our company.

     We have developed a set of financial, geographic and management criteria
designed to assist management in the evaluation of acquisition candidates. We
seek out acquisition candidates that have strong historical and projected
financial performance and experienced management teams that will be compatible
with our corporate culture and operating philosophy. In addition, we look for
acquisition candidates that satisfy one or all of the following criteria:

     - whether the acquisition will add additional and/or complementary
       technical capabilities,

     - whether the acquisition will augment our market share or increase our
       range of services,

     - composition and size of the candidate's customer base,

     - whether the geographic location of the candidate will enhance or expand
       our market area or ability to attract other acquisition candidates, and

     - potential synergies gained by combining the acquisition candidate with
       our existing operations.

     We anticipate that acquisition candidates will typically have annual
revenues ranging from $10 million to $40 million, although we would consider
acquiring a company with revenues outside this range. All acquisitions are
subject to initial evaluation and approval by our management before being
recommended to our board of directors. The evaluation by management includes
comprehensive financial, accounting and legal due diligence of the acquisition
candidate. We expect the management of our acquired companies to continue to
play an instrumental role in identifying and assisting in the completion of
future acquisitions.

     We expect to use Parent's equity or debt securities for all or a portion of
the consideration for future acquisitions. We may also be required to utilize
our cash resources to pursue our acquisition program, whether through additional
borrowings under our senior credit facilities, cash on hand or otherwise.

BIDDING AND CONTRACTS

     Our senior management team coordinates overall bidding strategies to
maximize the utilization of our resources, with all bids over $1.0 million being
approved by our senior management. Bids are prepared utilizing the local
expertise of our operating subsidiaries. When appropriate, our operating
subsidiaries work together in bidding for, winning and executing new contracts
by pooling their available resources, technical expertise and coverage in
different geographic areas.

     - turnkey agreements for comprehensive installation, design, engineering
       and maintenance services.


     Project-Specific Contracts. We refer to contracts covering bids for
particular services at specified prices as project-specific contracts.
Generally, these contracts cover most installation projects with a duration of
one year or longer. The majority of these contracts provide that we will furnish
a specified unit of service for a specified price. For example, we contract to
install cable for a specified rate per foot. Pro forma revenue for
project-specific contracts was approximately $156 million in 1997, $194 million
in 1998, $269 million in 1999 and $166 million for the six months ended June 30,
2000.



     Master Service Agreements. We refer to contracts with telecom services
providers to perform all work within a specific geographic area as master
service agreements. Under master service agreements, project services are
provided upon the execution of work orders, which will describe the work to be
undertaken. Each master service agreement contemplates hundreds of individual
installation and maintenance projects, generally resulting in less than $50,000
in revenue per project. These agreements generally have a term ranging from
three to five years and often contain price adjustment provisions based on
inflation. Under our master service agreements, our customers generally reserve
the right to use their own regularly employed personnel to perform services. In
addition, our customers generally retain the right to solicit competitive bids
with respect to projects that exceed a specified dollar amount, generally
$50,000. Pro forma revenue for master service agreements was approximately $41
million in 1997, $41 million in 1998, $40 million in 1999 and $31 million for
the six months ended June 30, 2000.



     Turnkey Agreements. We refer to contracts covering a comprehensive spectrum
of services, including the installation, design, engineering, and maintenance of
telecommunications and broadband networks on a fixed unit-priced basis, as
turnkey agreements. As we continue to grow and expand the scope of services we
provide, we are able to enter into an increasing number of contracts to provide
turnkey services. Even though these are generally long-term agreements, the
pricing for our services is not necessarily fixed because these agreements often
contain price adjustment provisions that are favorable to us, as well as
performance and completion incentives. Because turnkey contracts are invoiced
based on units of work completed at specified milestones per the contracts'
terms, these agreements require substantial initial working capital and
equipment, which historically have been partially funded by customer
prepayments. Pro forma revenue for turnkey agreements was approximately $0 in
1997, $5 million in 1998, $38 million in 1999 and $23 million for the six months
ended June 30, 2000.


     Our contracts for External Telecom Services are awarded on a competitive
basis, a negotiated basis, or a combination of the two depending on the nature
of the contract and the customer. Upon receipt of a request for proposal, we
develop a detailed bid which meets the unique specifications and requirements of
each project. This process often entails strategic business analysis, resource
planning, network design, cost and engineering studies and, in some cases,
development of financing alternatives for the project. Bids may be structured as
fixed price or cost plus, depending on the requirements of the request for
proposal, and are typically quoted on a per unit basis. In either case, we
believe that we enjoy a favorable competitive position due to our ability to
provide a full range of high quality installation, design, engineering and
maintenance services nationwide. Although master service agreements have
historically been awarded in a competitive bidding process, recent trends have
been toward securing or extending these contracts on negotiated terms. With the
rapid expansion of telecommunications and broadband networks, we believe that
more master service agreements will be awarded on the basis of negotiated terms
to the telecommunications or broadband services providers' preferred providers,
as opposed to the competitive bidding process. All of our External Telecom
Services contracts are generally terminable upon 90 days' notice or less.

     INTERNAL TELECOM SERVICES


     EF&I Services Contracts. We generally provide EF&I Services on a
project-by-project basis. Each of these projects generates average revenue of
approximately $20,000 and requires from two weeks to three months to complete,
with the majority completed in less than a month. In 1998 we completed
approximately 5,000 individual EF&I Services projects, and in 1999, we completed
approximately 8,000 additional projects. Pro forma revenue for EF&I Services
contracts was $21 million in 1996, $40 million in 1997, $76 million in 1998,
$145 million in 1999 and $127 million for the six months ended June 30, 2000.


     Regional Bell Operating Companies are our primary customers for EF&I
Services. We typically secure two or three-year, fixed price agreements with the
Regional Bell Operating Companies, who generally establish non-binding contracts
with only "preferred" vendors. We have achieved preferred status with many of
our customers, including Bell Atlantic and Ameritech. These non-binding
contracts outline the payment terms and pricing parameters for various types of
projects. Although these contracts do not stipulate a minimum amount of work to
be designated to a vendor during the term of the contract, preferred provider
status does act as a barrier to entry, allowing preferred providers to perform
their services at their maximum service capacity. Regional Bell Operating
Companies such as Bell Atlantic typically limit their number of preferred
vendors to between three and six vendors per region.

     We calculate the pricing of our projects for other customers based on the
type of equipment to be installed and the complexity of the engineering and
installation services required. We generally recognize revenue from EF&I
Services contracts on our books as a percentage of project completion, with
completion being measured by comparing actual costs incurred to estimated
project costs, and bill our customers at job completion. Because our EF&I
projects are generally short in duration (two weeks to three months, but
generally less than one month) and are for less than $20,000, this method of
revenue recognition does not present any material risk of misstating revenues.
The lag between completion and billing is approximately two weeks and payments
are due within 45 days from the billing date (net 30 terms). Progress billing is
only allowed in the Bell Atlantic contract and on a job-by-job negotiated basis
with other customers.

     Network Services Contracts. We generally provide our Network Services on a
project-by-project basis for a fixed fee and recognize revenue on a percentage
of completion basis as our costs are incurred. Each of these projects generates
average revenue of approximately $15,000 and generally requires one week to 30
days to complete. These contracts are generally billed upon project completion.
We also provide our Network Services under maintenance agreements, under which
we agree to furnish a specified unit of service for a specified price and bill
our customers based on the services performed.

CUSTOMERS


     We regularly serve a diverse group of more than 300 customers, which can be
categorized in three broad market segments:


     - telecommunications services providers, such as Regional Bell Operating
       Companies, incumbent local exchange carriers, competitive local exchange
       carriers, long-distance service providers and independent telephone
       companies, which accounted for approximately 60% of our pro forma 1999
       revenue;

     - broadband services providers, such as Media One and Time Warner, which
       accounted for approximately 33% of our 1999 pro forma revenue; and

     - commercial entities, such as Dell and Compaq, governmental entities such
       as the FDIC, and institutional entities, such as utility providers and
       public school districts, requiring Network Services, which together
       accounted for approximately 7% of our 1999 pro forma revenue.

     In recent months, our revenue from Verizon has increased in both absolute
terms and as a percentage of our revenue and this trend may continue for the
foreseeable future. Verizon contributed approximately 61% of LISN's 1998
revenue. Because LISN's business with Verizon is governed by 13 separate
relationships with individual Verizon operating units that are each
independently responsible for issuance of work orders to LISN within their
operating regions, customer diversification effectively exists within the
Verizon relationship, since a change in our relationship with one unit will not
necessarily affect our relationship with the other units. Verizon's need for
telecom infrastructure services has kept LISN operating at or near full capacity
for the past seven years in the regions LISN serves Verizon.

SALES AND MARKETING

     Our sales and marketing efforts are focused on increasing the value of
comprehensive services provided to existing customers, actively cross-marketing
additional services to our existing customer base and developing new customer
relationships. These efforts are primarily the responsibility of regional
management, supplemented by our executive management team with respect to
national accounts. Regional management at each of our operating subsidiaries has
been responsible for developing and maintaining successful long-term
relationships with customers, which helps facilitate our repeat business and
generate cross-marketing opportunities.

     We currently have a sales and marketing integration team, comprised of
executive management of Parent and senior management of its subsidiaries,
including LISN, working to maximize our sales and marketing opportunities. This
team is actively identifying logical cross-selling opportunities, developing
procedures for joint-bidding and developing procedures for delivering sales
opportunities to the business unit best positioned to respond to the customer's
requirements.

     Many of our customers or prospective customers have a qualification
procedure for becoming an approved vendor based upon the satisfaction of
particular performance and safety standards set by the customer. These customers
often maintain a list of vendors meeting their standards and award contracts for
individual jobs only to vendors which meet their standards. This customer
approval process has been expedited by LISN's achievement in September 1998 of
ISO 9002 certification. We strive to maintain our status as a preferred and
qualified vendor to these customers.

BACKLOG

     We define our backlog as the uncompleted portion of services to be
performed under project specific contracts and the estimated value of future
services that we expect to provide under master service agreements and other
contracts. As of June 30, 2000, our pro forma backlog was approximately $663
million. Of that amount, approximately $303 million was for work scheduled to be
performed in 2000

                                       65
<PAGE>   70

and approximately $318 million is for work scheduled to be performed in 2001.
All our backlog can be canceled at any time upon the notice provided in these
agreements without penalty except, in some cases, for the recovery of our actual
committed costs and profit on work performed up to the date of cancellation.
However, we have not historically had any significant cancellations. We are
unable to provide backlog information for periods prior to 1999 since our
subsidiaries did not maintain any consistent information on contract backlog
prior to their acquisition by Parent.

     Under our master service agreements and certain of our maintenance
contracts, our customers do not commit to the volume of services to be
purchased. Rather, these contractual provisions commit us to perform these
services if requested by the customer and commit the customer to obtain these
services from us if they are not performed internally. Many of the contracts are
multi-year contracts and we include revenues from all the services projected to
be performed over the life of the contract in our backlog based upon our
historical relationships with our customers and experience in these types of
contracts.

SAFETY AND RISK MANAGEMENT

     We are committed to ensuring that our employees perform their work in a
safe environment. We regularly communicate with our employees to promote safety
and to instill safe work habits through our company-wide employee training and
educational programs. We have dedicated risk managers at each of our operating
subsidiaries who review all accidents and claims, examine trends and implement
changes in procedures or communications to address any safety issues. We also
have a dedicated risk manager at our corporate headquarters who monitors the
risk management programs at our subsidiaries and establishes overall corporate
risk management objectives and standards.

EMPLOYEES


     As of June 30, 2000, we had approximately 5,885 employees, approximately
15% of whom were salaried, approximately 80% of whom were paid on an hourly
basis and approximately 5% of whom were paid on a production basis. Our hourly
employees have an average hourly wage of $15 per hour. Our employees are
generally non-union, although we do provide union labor when required, as in
certain markets such as New York City. As of June 30, 2000, approximately 20% of
our employees were affiliated with unions. We maintain a core of technical and
managerial personnel from which we draw to supervise all projects. As the need
arises, we also subcontract with independent contractors to supply additional
manpower to complete specific projects. As of June 30, 2000, on a pro forma
basis, we had approximately 1,800 subcontracted workers. We consider relations
with our employees to be good.


     We employ more than 750 qualified installers with skill levels that meet or
exceed Bellcore GR-1275-CORE section 23, an industry-wide quality standard.
Technicians go through a two-week formal training period and an estimated 12 to
18 more months on the job before they are fully trained. Most of the technicians
have a trade school/high school education or have prior experience in the
telecom sector. Recruiting, training and retaining technicians is a key focus
area for us.

EQUIPMENT AND FACILITIES

     We operate a fleet of owned and leased trucks and trailers, support
vehicles and specialty installation equipment, such as backhoes, excavators,
trenchers, generators, boring machines, cranes, wire pullers and tensioners. The
total size of the equipment fleet is approximately 2,200 units. We believe that
these vehicles generally are well-maintained and adequate for our present
operations. We believe that in the future, we will be able to lease or purchase
this equipment at favorable prices due to our larger size and the volume of our
leasing and purchasing activity.

     Our corporate headquarters are located in leased space in West Palm Beach,
Florida. The total leased area for our corporate headquarters and our
subsidiaries' headquarters that are leased is approximately 283,611 square feet
and the total annual base rent for these facilities is approximately $2.0
million. The leases for these facilities have terms ranging from month-to-month
to five years. None of the individual leases is material to our operations.

     The following is a list of our facilities, each of which is leased, with
the exception of the headquarters for Schatz Underground Cable in Villa Ridge,
Missouri, which includes the training, warehouse and distribution facility, the
Schatz Underground Cable regional office in Kansas City, Missouri, the LISN
headquarters in Amherst, Ohio and LISN's training and regional office in Lorain,
Ohio. In addition to those facilities listed, our subsidiaries also lease
various district field offices, equipment yards, shop facilities and temporary
storage locations. We also lease other smaller properties as necessary to enable
us to efficiently perform our obligations under master service agreements and
other contracts. We believe that our facilities are generally adequate for our
needs. We do not anticipate difficulty in replacing any facilities or securing
additional facilities, if needed. All of our owned properties and our leases are
pledged to secure repayment of the senior credit facilities.

COMPETITION


     The telecom infrastructure services industry is highly fragmented. We
believe that the seven largest public companies in the industry, together with
Orius, accounted for less than 6% of total estimated industry revenues in 1999,
with Orius accounting for approximately 1%. The industry consists of a small
number of large companies with a national presence and hundreds of smaller local
and regional companies that generally have more limited service capabilities and
geographic coverage. The telecom infrastructure industry is highly competitive,
requiring substantial resources and skilled and experienced personnel. We
compete with other companies in all of the markets in which we operate, some of
the larger of which may have greater financial, technical and marketing
resources than we do, including Dycom Industries, Inc., MasTec, Inc., Quanta
Services, Inc. and others. There are relatively few barriers to entry into the
markets in which we operate and, as a result, any organization that has adequate
financial resources, access to technical expertise and customer relationships
may become a competitor to us. We may also face competition from the in-house
service organizations of our existing or prospective customers which often
employ personnel who perform some of the same types of services as those
provided by us. Although a significant portion of these services is currently
outsourced, we cannot assure you that our existing or prospective customers will
continue to outsource service requirements for installation, design, engineering
and maintenance services in the future.


     We believe that the principal competitive factors in the telecom
infrastructure industry include technical expertise, reputation, price, quality
of service, availability of skilled technical personnel, geographic presence,
breadth of service offerings, adherence to industry standards and financial
stability. We believe that we compete favorably within our industry on the basis
of these factors.

LEGAL PROCEEDINGS

     We occasionally are a party to legal proceedings incidental to our ordinary
business operations. At present, we are not a party to any pending legal
proceedings that we believe could have a material adverse effect on our
business, financial condition or results of operations.

ENVIRONMENTAL MATTERS

     Our facilities and operations are subject to federal, state and local
environmental and occupational health and safety requirements, including those
relating to discharges of substances to the air, water and land, the handling,
storage and disposal of wastes and the cleanup of properties affected by
pollutants. We do not currently anticipate any material adverse effect on our
business or financial condition as a result of our efforts to comply with such
requirements.

     In the future, federal, state, local or foreign governments could enact new
or more stringent laws or issue new or more stringent regulations concerning
environmental and worker health and safety matters that could effect our
operations. Also, in the future, contamination may be found to exist at our
facilities or off-site locations where we have sent wastes. We could be held
liable for any newly-discovered contamination. It is possible that changes in
environmental and worker health and safety requirements or liabilities from
newly-discovered contamination could have a material effect on our business.

    LISN acquisition.

EXECUTIVE EMPLOYMENT AGREEMENTS

     Mr. Mercurio. In connection with the LISN acquisition, Parent entered into
a senior management agreement with Mr. Mercurio. The agreement provides that Mr.
Mercurio shall serve as president, chief executive officer and chairman of the
board of Parent and shall devote his full business time and attention to its
affairs. The agreement is for a term ending on February 28, 2003. Mr. Mercurio
is entitled under the agreement to a base salary equal to $470,000 per year,
which may be increased by the board in its discretion and will be subject to
yearly increases based on the Consumer Price Index. In addition to his base
salary, Mr. Mercurio is entitled to receive an annual bonus based upon Parent's
financial performance, as measured by its EBITDA. Mr. Mercurio will not receive
a bonus unless Parent's EBITDA is greater than 1.125 times its prior year's
EBITDA. If EBITDA exceeds this amount, Mr. Mercurio is entitled to receive a
bonus ranging from 50% to 100% of his base salary.

     Parent and Mr. Mercurio may each terminate the agreement at any time, with
or without cause, provided that, if we terminate Mr. Mercurio without "cause,"
or if he terminates his employment with "good reason," we must continue to pay
him his base salary for two years and must pay him a pro rata portion of his
bonus for the year of his termination. "Cause" includes the commission of a
felony or a crime involving moral turpitude; an act or omission with respect to
Parent involving dishonesty or fraud that has resulted in or is likely to result
in material harm to Parent; chronic drug or alcohol use; the repeated failure to
perform his duties as directed by the board; negligent or willful misconduct
with respect to Parent; or the material breach of the terms of his management
agreement. "Good reason" means the relocation of our executive offices outside
of West Palm Beach, Florida; a material breach by us of the terms of the
management agreement; or the assignment to Mr. Mercurio of duties inconsistent
with his position at Parent.

     If Parent terminates Mr. Mercurio for cause or if he terminates his
employment without good reason, he would be entitled to receive only his base
salary through the date of termination. If Mr. Mercurio is

                                       72
<PAGE>   77

terminated for disability, he is entitled to receive his base salary for six
months. In the event the agreement is terminated according to its terms in
February 2003, Parent may, at its option, continue to pay Mr. Mercurio his base
salary for one year as a severance payment. Mr. Mercurio has agreed not to
compete with Parent until the later of (1) the second anniversary of the
termination of the management agreement if Mr. Mercurio resigns without good
reason or is terminated with cause or (2) the time as we cease making any
severance payments to him under the management agreement.

     Under the management agreement, Parent agreed to sell to Mr. Mercurio
shares of Parent's common stock equal to .75% of its outstanding common stock
for a price per share equal to the price at which shares were purchased by all
investors in the LISN acquisition. Mr. Mercurio purchased these shares on
January 16, 2000 by issuance of a promissory note in the amount of $252,633,
which is secured by a pledge of the 188,810 shares purchased. The note bears
interest at a rate of 5.88% per annum. Fifty percent of these shares will vest
over four years. The remaining 50% vest on the fifth anniversary of the closing
of the LISN acquisition, provided that vesting will be accelerated with respect
to 25% of this 50% in each year that Parent achieves its EBITDA target. All of
Mr. Mercurio's shares will become immediately vested upon the occurrence of the
following events: (1) Willis Stein & Partners ceases to own 50% of the shares
owned by it as of the closing of the LISN acquisition, (2) if prior to an
initial public offering of Parent, a person or group of persons who were not
stockholders immediately after the LISN acquisition acquire a number of shares
necessary to elect a majority of the board or (3) a change of control occurs. A
"change of control" means (1) any person who was not a stockholder immediately
following the LISN acquisition owns the greater of (a) 25% of Parent's voting
stock or (b) the greatest combined voting power of any person who was a
stockholder immediately following the LISN acquisition; (2) during any two year
period, persons who constituted the board at the beginning of the period cease
to constitute a majority of the board; (3) if Parent consummates a merger and
stockholders who were stockholders prior to the merger cease to own 80% of the
surviving company's equity; (4) a sale of all or substantially all of Parent's
assets; or (5) any person commences a tender offer or receives an option to
acquire 25% or more of Parent's voting stock, unless the board makes a good
faith determination that this action would not constitute a material change in
the control of Parent.

     If Mr. Mercurio ceases to be employed by Parent for any reason, Parent will
have the option to repurchase his unvested shares at their original cost. Parent
will be able to purchase his vested shares only if he fails to repay the
promissory note issued to purchase the shares within 60 days following his
termination. Mr. Mercurio's shares will be subject to the restrictions on
transfer contained in the investor rights agreement, described under the heading
"Certain Relationships and Related Party Transactions -- Investor Rights
Agreement."

     Messrs. Agres and Powers. Parent also entered into employment agreements
with Mr. Agres and Mr. Powers. Mr. Agres' agreement provides that he will be
employed as Chief Financial Officer for a term ending December 14, 2001 and will
receive a base salary of $195,000 per year. Mr. Powers agreement provides that
he will be employed as a Vice President for a term ending February 28, 2003 and
will receive a base salary of $230,000 per year. Parent may terminate Messrs.
Agres' and Powers' employment at any time for "cause," which includes (1) a
material breach of the terms of the executive's agreement, (2) willful
misconduct in the performance of the executive's duties; (3) an act of fraud
intended to result in the executive's enrichment at Parent's expense, (4)
conviction of a felony or fraud, (5) entry of an order preventing the executive
from performing activities that are essential to the performance of the
executive's agreement, or (6) willful or deliberate conduct intended to
materially damage Parent's business. If either of Messrs. Agres or Powers is
terminated for cause or voluntarily terminates his employment, he would be
entitled to receive his base salary through the date of termination. If either
Messrs. Agres or Powers is terminated due to disability, he would be entitled to
receive his base salary for one year following termination. If either is
terminated without cause, he would be entitled to receive his base salary for
the remainder of his employment term. Mr. Agres has agreed not to compete with
Parent for a period ending the later of (1) December 14, 2001 and (2) one year
after the termination of his employment. Mr. Powers has agreed not to compete
with Parent for a period ending the later of (1) February 28, 2003 or (2) one
year after the termination of his employment.

     Mr. Vanke. Mr. Vanke has an employment agreement with LISN, dated May 28,
1999, which expires on May 27, 2001. Mr. Vanke's employment agreement provides
that he will serve as President and Chief Executive Officer of LISN and will
receive a base salary of $300,000. In addition, Mr. Vanke receives a bonus equal

LISN, as determined by Mr. Vanke and LISN's board of directors prior to the
start of each fiscal year. If LISN terminates Mr. Vanke without cause or if he
terminates his employment for good reason prior to May 2001, LISN must pay Mr.
Vanke his base salary through the later of six months following his termination
or through May 2001. If Mr. Vanke's employment is terminated for cause or if he
terminates his employment without good reason, he will be entitled to only his
base salary through the date of termination. "Cause" includes (1) the commission
of a felony or fraud, (2) chronic drug or alcohol abuse or conduct causing LISN
substantial public disgrace, (3) substantial and repeated failure to perform his
duties as directed by LISN's board of directors, (4) gross negligence or willful
misconduct or (5) any other material breach of his employment agreement. "Good
Reason" includes the relocation of LISN's offices outside of the Cleveland, Ohio
area or the Company's breach of the terms of the employment agreement. Mr. Vanke
has agreed not to compete with LISN during his employment and for two years
thereafter.

     - Parent's chief executive officer, who will initially be Mr. Mercurio;

     - the remainder shall be designated by Willis Stein & Partners, and

     The investor agreement generally restricts the transfer of any shares of
Parent's stock or junior subordinated notes held by the parties to the investor
agreement by requiring that Willis Stein & Partners approve any transfers of
these securities, with some limited exceptions. The parties to the investor
agreement have granted Parent a right of first refusal with respect to its stock
and junior subordinated notes, which, if not exercised by Parent, may be
exercised by Willis Stein & Partners and some of its other stockholders. Each
party to the investor agreement has the right to participate in any transfer of
shares by any other party to the agreement, with some limited exceptions. In
addition, Parent has agreed not to issue

parties to the investor agreement are given the opportunity to purchase their
pro rata share on substantially the same terms. Each party to the investor
agreement has agreed to consent to a sale of Parent if Willis Stein & Partners
votes to approve the sale.

     The investor agreement also provides that Willis Stein & Partners may
request, at any time, that all or any portion of its common stock or class B
common stock be registered with the SEC. In the event that Willis Stein &
Partners makes a request for registration, the other parties to the investor
agreement who hold common stock or class B common stock will be entitled to
participate in the registration. Parent has also granted the parties to the
investor agreement piggyback registration rights with respect to registrations
by it and Parent has agreed to pay all expenses relating to the piggyback
registrations.

common stock and 634.92 shares of Parent series C preferred in connection with
the LISN acquisition.

1999 ACQUISITIONS

     In February 1999, we acquired Schatz, DAS-CO, Copenhagen and Network in a
transaction that was designed to give tax-free treatment to the issuance of
stock to the former stockholders of the acquired companies. To complete these
acquisitions all of the existing stockholders of these companies exchanged their
interests in the respective companies for new interests in Parent. HIG acquired
7,546.38 shares of Parent's series B preferred stock for $7.6 million, which was
redeemed in connection with the LISN acquisition for an aggregate of $44.0
million in cash. Parent also sold 1,066,219 shares of its common stock to its
then existing stockholders and employees for $2.4 million. The following
officers, directors and former principal stockholders, and their immediate
family members and affiliated entities, purchased the number of shares indicated
at $2.34 per share in cash: Mr. Mercurio -- 132,319, Mr. Agres -- 41,444, and
Mr. Mullen -- 106,717. In connection with the 1999 acquisitions, Parent paid (1)
Mercurio and Associates, PA., an affiliate of Mr. Mercurio, a consulting fee of
$550,000 for assistance in identification of, and due diligence with respect to,
acquisition candidates and (2) HIG $267,000 for fees and expenses.


     In May 1999, we acquired the stock of Texel Corporation from Mr.
Kasprowicz, one of our executive officers, for $26.3 million in cash plus the
issuance of 1,030,335 shares of Parent's common stock. In


                                       76
<PAGE>   81


September 2000, we paid Mr. Kasprowicz approximately $3.0 million in settlement
of litigation brought by Mr. Kasprowicz, alleging that amounts were owed to him
as a purchase price adjustment in connection that purchase. In return for this
payment, Mr. Kasprowicz has released all claims against Orius relating to this
matter.


RECAPITALIZATION OF LISN

     LISN was recapitalized in May 1999 by an investor group led by Willis Stein
& Partners, certain co-investors and members of LISN's management. Willis Stein
& Partners and its co-investors contributed approximately $70.3 million in
capital. Willis Stein & Partners and its co-investors received $49.2 million in
junior subordinated notes, $10.6 million in preferred stock and $10.5 million in
common stock. Members of management retained approximately 15% of LISN's equity.

     In connection with the recapitalization, LISN agreed to make a cash payment
to three of its former stockholders based on LISN's results of operations for
the year ended December 31, 1999, including Mr. Vanke. Based on LISN's results
of operations, LISN paid these stockholders an aggregate of $4.0 million, $0.5
million of which was paid to a trust formed for the benefit of Mr. Vanke.

FAMILY RELATIONSHIPS

     Rosemarie Mulholland, the daughter of Mr. Mercurio, is Parent's Secretary
and Treasurer. Ms. Mulholland, a certified public accountant, received total
compensation of $90,967 from us in 1999, including a salary of $80,467 and an
accrued bonus of $10,500. Ms. Mulholland also received options to purchase 9,325
shares of our common stock, which were repurchased in connection with the LISN
Acquisition for $77,701 in cash.

                       DESCRIPTION OF PARENT'S SECURITIES

GENERAL


     Parent's authorized capital stock consists of: 10,000 shares of series A
convertible preferred stock, par value $.0001 per share; 7,596.38 shares of
series B convertible preferred stock, par value $.0001 per share; 200,000,000
shares of series C participating preferred stock, par value $.01 per share;
200,000,000 shares of series D preferred stock, par value $.01 per share;
200,000,000 shares of common stock, par value $.01 per share; and 200,000,000
shares of class B common stock, $.01 per share. As of June 30, 2000, there were
no shares of series A preferred stock, no shares of series B preferred stock,
205,739.77 shares of series C preferred stock, no shares of series D preferred
stock, no shares of class B common stock and 25,887,559.27 shares of common
stock outstanding. Parent's classes of stock generally differ with respect to
dividend payment, liquidation preference, redemption, conversion and voting
rights. All classes of its stock vote together as a class on all matters to be
voted upon by its stockholders. The common stock is entitled to one vote per
share, the class B common is entitled to 10 votes per share and the series C
preferred stock is entitled to 75 votes per share.


SERIES C PREFERRED STOCK

     Dividends on the series C preferred stock accrue daily at a rate of 12% per
annum on the liquidation value of the series C preferred stock plus all
accumulated and unpaid dividends. The liquidation value of the series C
preferred stock is $1,000. These dividends are cumulative and must be paid
before dividends are paid on any shares of common stock. Holders of series C
preferred stock also participate in any dividends paid to the holders of common
stock on an as converted basis. Upon a liquidation of Parent, the holders of
series C preferred stock would be entitled to receive the liquidation value of
their stock plus accrued and unpaid dividends prior to any distributions to the
holders of common stock. The series C preferred stock will be redeemed on
December 31, 2019 at its purchase price, plus accrued dividends and plus the
liquidation value of the common stock into which it is convertible.

     Upon the consummation of an initial public offering, the holders of a
majority of the series C preferred stock may cause all or any portion of the
outstanding series C preferred stock to be converted into (1) shares of class B
common (or, if no shares of class B common are outstanding, common stock), and
(2) shares of series D preferred stock. Each holder of series C preferred stock
will receive (1) a number of shares of common stock equal to series C
liquidation value divided by the conversion price for the series C preferred
stock and (2) the number of shares of series D preferred stock with a
liquidation value equal to the liquidation value of the series C preferred stock
converted, plus accrued and unpaid dividends.

     The series D preferred stock is similar in rights and preferences to the
series C preferred stock, but is not convertible into common stock and is
redeemable by Parent at any time. In addition, a majority of the holders of the
series D preferred stock may cause Parent to redeem some or all of the series D
preferred stock at any time. Parent may pay the redemption price for the series
D preferred stock by issuance of common stock with an equivalent fair market
value in lieu of cash if it is prohibited by the terms of its debt from making
the redemption payment in cash or if the holders of the series D preferred stock
do not object to receiving the redemption payment in common stock.

COMMON STOCK

     Dividends on the common stock are payable when and as declared by Parent's
board of directors, subject to the rights of the holders of any preferred stock.
The holders of the common stock participate in any distributions upon
liquidation ratably, subject to the rights of the holders of its preferred
stock.

JUNIOR SUBORDINATED NOTES

     As of June 30, 2000, there was $141.7 million of Parent's junior
subordinated notes outstanding. The LISN acquisition resulted in each
stockholder of Parent, except to the extent the stockholder's shares are subject
to put and call agreements, owning Parent common stock, series C preferred stock
and junior subordinated notes with fair values representing approximately
9%-54%-37%, respectively, of the fair market value of the securities. Parent's
obligations under the junior subordinated notes are subordinated to all of
Parent's senior debt (as defined under the terms of the junior subordinated
notes), including its guarantee in respect of the senior credit facilities and
the notes. The junior subordinated notes bear interest at a rate of 12.0% per
annum, a maximum of 40% of which is payable in cash beginning January 15, 2001,
and the remainder of which is deferred and accrues as additional principal. In
addition, after December 15, 2004, if at the end of any interest accrual period
the amount of accrued and unpaid original issue discount exceeds an amount equal
to the product of the issue price and the yield to maturity (the "Maximum
Amount"), then interest will be paid so as to reduce the unpaid original issue
discount to an amount less than the Maximum Amount. Cash interest can be paid by
Parent only to the extent Parent has available funds and only so long as the
payments are permitted under the terms of, among other things, the senior credit
facilities and the notes.

     Because Parent is a holding company with no independent operations, the
only sources of funds for making payments on the subordinated promissory notes
are (1) dividends from NATG, the payment of which is limited by the terms of the
senior credit facilities and the notes and (2) additional capital contributions
from its stockholders. If there is a default under the junior subordinated notes
because NATG is prohibited under the terms of the senior credit facilities or
the notes from paying sufficient dividends for Parent to meet its cash interest
obligations under its junior subordinated notes, or if Parent otherwise defaults
on its obligations in respect of the junior subordinated notes, the holders of
the junior subordinated notes will be prohibited from taking any actions or
exercising any remedies against Parent or any of its subsidiaries until all
senior debt, including the senior credit facilities and the Notes, has been
repaid in full; provided, that the holders may accelerate their junior
subordinated notes if senior debt is accelerated, but are prohibited from taking
any further action. The junior subordinated notes become due and payable on the
later of (1) December 15, 2009 and (2) the first anniversary of the date on
which any debt raised in a high yield offering, such as the notes being issued
in this offering, is repaid.

<PAGE>   85

                    DESCRIPTION OF SENIOR CREDIT FACILITIES

     General. In connection with the LISN acquisition, NATG entered into the
senior credit facilities with Bankers Trust Company, Bank of America, N.A. and
certain other lenders. The senior credit facilities were amended and restated on
July 5, 2000 to provide for the tranche C term loan. The senior credit
facilities provide for aggregate borrowings of approximately $435.0 million. The
senior credit facilities consist of the following:

     - $75.0 million tranche A term loan with a $50.0 million letter of credit
       subfacility;

     - $200.0 million tranche B term loan;

     - $60.0 million tranche C term loan; and

     - $100.0 million revolving credit facility to be used for permitted
       acquisition loans and for working capital purposes, with sublimits of
       $75.0 million for acquisition loans and $50.0 million for working capital
       loans and a maximum of $100.0 million in borrowings at any one time.

     As of July 5, 2000, there was $288.6 million of outstanding indebtedness
under the senior credit facilities (excluding $2.0 million of letters of credit)
and $50.0 million available under the senior credit facilities for working
capital and other corporate purposes and $75.0 million available for
acquisitions, although no more than $100.0 in the aggregate may be borrowed
under the revolving credit facilities. The amount outstanding under the senior
credit facilities includes $5.7 million of letters of credit issued under the
tranche A term loan letter of credit subfacility. These letters of credit
support the obligations under put and call agreements with some of Parent's
stockholders. These letters of credit will be drawn to fully fund the amounts
payable upon exercise of our call options. In addition, the amount available for
working capital loans has been reduced by $7.2 million of letters of credit
issued under the revolving credit facility to support other contingent
obligations in connection with the put and call agreements. These letters of
credit will expire in accordance with their terms without being drawn upon
exercise of the call options. We used a portion of the proceeds of the offering
of the outstanding notes to repay a portion of the tranche B term loan. See "Use
of Proceeds."

     Interest. Amounts outstanding under the senior credit facilities bear
interest, at our option, at a rate per annum equal to either (1) the base rate
or (2) the eurodollar rate, as determined by Bankers Trust Company, in each case
plus an additional margin. The base rate is the higher of (x) the rate announced
from time to time by Bankers Trust Company as its prime lending rate, and (y)
the overnight federal funds rate plus 0.5%. The additional margin for the
revolving credit facility, including for any acquisition loans converted into
term loans under that facility, and the tranche A term loan is initially 2.0%
for base rate loans and 3.0% for eurodollar rate loans. The additional margin
for tranche B term loans is initially 2.5% for base rate loans and 3.5% for
eurodollar rate loans and the additional margin for the tranche C term loans is
initially 2.75% for base rate loans and 3.75% for eurodollar rate loans. The
additional margin for tranche A term loans and the revolving credit facility
adjusts according to a performance pricing grid based on our ratio of total debt
to EBITDA, ranging from (1) for base rate loans, 2.0% to 0.75% and (2) for
eurodollar rate loans, 3.0% to 1.75%. As of July 5, 2000, our borrowings under
the senior credit facilities bore interest at rates ranging from 9.6% to 10.3%.

     Maturity. Borrowings under the revolving credit facility that are used for
working capital purposes are due December 15, 2004 and may be borrowed, repaid
and reborrowed prior to maturity. Until December 15, 2001, amounts borrowed
under the revolving credit facility that are used for acquisitions may be
borrowed, repaid and reborrowed. On December 15, 2001, (1) any acquisition loans
outstanding will be converted into an amortizing term loan, payable quarterly,
with 20% of the loan payable in 2002, 25% of the loan payable in 2003 and 55% of
the loan payable in 2004, with the final payment due December 15, 2004 and (2)
to the extent that acquisition loans exceed $50.0 million on that date, amounts
available for working capital purposes will be permanently reduced to the
difference between $100.0 million and the amount of the converted acquisition
loans.

                                       81
<PAGE>   86

     Borrowings under the tranche A term loan are due December 15, 2004,
borrowings under the tranche B term loan are due December 15, 2006 and
borrowings under the tranche C term loan are due December 15, 2007. The tranche
A and tranche B term loans are payable quarterly in arrears beginning March 31,
2000. The tranche C term loans are payable quarterly in arrears beginning
September 30, 2000. The tranche A, tranche B and tranche C term loans will be
repaid as provided in the following annual amortization schedule.

     Mandatory Prepayments. Parent must prepay the loans outstanding under the
senior credit facilities with (1) the net proceeds of specified asset sales, (2)
any "excess cash flow," as defined in the senior credit agreement, as of the
95(th)day following the end of each of Parent's fiscal years, (3) 50% of the net
offering proceeds from the sale of Parent's equity securities or junior
subordinated notes, and (4) the proceeds of the incurrence of any indebtedness,
in each case subject to the exceptions set forth in the senior credit agreement.

     Prepayment Penalty on Tranche B Term Loan. If we repay all or any portion
of the tranche B term loan or tranche C term loan prior to December 15, 2001, we
must repay these term loans at 101% of their principal amount. The portion of
the tranche B term loan repaid with the proceeds of the offering of the
outstanding notes was repaid at 101% of the principal amount repaid.

     Use of Proceeds. Subject to the applicable sublimits, the proceeds of the
revolving credit facility are available solely for working capital purposes,
capital expenditures and other general corporate purposes and to finance
acquisitions permitted under the terms of the senior credit facilities, subject
to restrictions on the number and value of acquisitions made. The proceeds of
the tranche A and tranche B term loans were used to finance the LISN acquisition
and were fully drawn down at the closing of the LISN acquisition, other than the
letters of credit issued under the tranche A term loan letter of credit
subfacility, which loans will be made when the letters of credit are drawn upon
in connection with our exercise of the call options. Tranche A and tranche B
term loans may not be reborrowed. The proceeds of the tranche C term loan were
used to repay loans outstanding under the revolving credit facility and related
fees and expenses and may not be reborrowed.

     Security and Guarantees. The senior credit facilities are secured by a
first priority security interest in substantially all of our existing and
after-acquired tangible and intangible assets, including, without limitation,
receivables, contract rights, securities, intellectual property, inventory,
equipment, real estate and all stock and promissory notes, with the exception
that no more than 65% of the voting stock of any of our foreign subsidiaries
shall be pledged. All of the borrowers' obligations under the senior credit
facilities are fully and unconditionally guaranteed by all of its present and
future domestic subsidiaries and by Parent.

     Covenants. The senior credit facilities require us to meet certain
financial tests, including, without limitation, minimum net worth, maximum

acquisition facility are subject to additional debt incurrence tests. The senior
credit facilities contain certain covenants, including the following:

     - restrictions on indebtedness;

     - restrictions on mergers, consolidations and some types of acquisitions
       and asset sales;

     - restrictions on dividends and stock repurchases; and

     - restrictions on the types of businesses in which we can engage.

     Events of Default. The senior credit facilities contain customary events of
default, including, without limitation:

     - payment defaults;

     - breaches of representations and warranties;

     - covenant defaults;

     - cross-defaults to certain other indebtedness, including the Notes;

     - certain events of bankruptcy and insolvency;

     - the failure of any guaranty or security document supporting the senior
       credit facilities to be in full force and effect; and

     - a change of control of Parent.

                            DESCRIPTION OF THE NOTES

     The outstanding notes were issued under an indenture among the issuers,
Parent, the other guarantors and United States Trust Company of New York, as
trustee. The following is a summary of the material provisions of the indenture.
It does not include all of the provisions of the indenture. We urge you to read
the indenture because it defines your rights. The terms of the notes include
those stated in the indenture and those made part of the indenture by reference
to the Trust Indenture Act of 1939, as amended. A copy of the indenture may be
obtained from the issuers. You can find definitions of certain capitalized terms
used in this description under "-- Certain Definitions."

     The notes are unsecured obligations of the issuers, ranking subordinate in
right of payment to all senior debt to the extent set forth in the indenture.

     The issuers issued the notes in fully registered form in denominations of
$1,000 and integral multiples of $1,000. The trustee presently is acting as
paying agent and registrar for the notes. The notes may be presented for
registration of transfer and exchange at the offices of the registrar, which is
currently the trustee's corporate trust office. The issuers may change any
paying agent and registrar without notice to holders of the notes. The issuers
will pay principal, and premium, if any, on the notes at the trustee's corporate
trust office in New York, New York. At the issuers' option, interest may be paid
at the trustee's corporate trust office or by check mailed to the registered
address of holders of the notes.

     Any notes that remain outstanding after the completion of the exchange
offer, together with the exchange notes issued in connection with the exchange
offer, will be treated as a single class of securities under the indenture.

     In the event that Parent ceases to own and control a majority of the voting
securities of NATG, all references in the indenture to Parent's board of
directors will be deemed to be references to NATG's board of directors.

PRINCIPAL, MATURITY AND INTEREST

     Notes in an aggregate principal amount of $150.0 million were issued on the
original issue date of the notes. Additional notes may be issued from time to
time, subject to the limitations set forth under "-- Certain
Covenants -- Limitation on Incurrence of Additional Indebtedness." The aggregate
principal amount of notes issued under the indenture shall not exceed $300.0
million. The notes will mature on February 1, 2010.

     Interest on the notes will accrue at the rate of 12 3/4% per annum and will
be payable semiannually in cash on each February 1 and August 1 commencing on
August 1, 2000, to the persons who are registered holders at the close of
business on the fifteenth day of the month immediately preceding the applicable
interest payment date. Interest payable at maturity will be payable to the
person to whom principal is payable. Interest on the notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from and including the original issue date of the notes. The interest rate
on the notes is subject to increase in some circumstances.

     The notes will not be entitled to the benefit of any mandatory sinking
fund.

REDEMPTION

     Optional Redemption. Except as described below, the notes are not
redeemable before February 1, 2005. After February 1, 2005, the issuers may
redeem the notes at their option, in whole or in part, upon not less than 30 nor
more than 60 days' notice, at the following redemption prices if redeemed during
the

                                       84
<PAGE>   89

twelve-month period commencing on February 1 of the year set forth below. The
redemption prices are expressed as percentages of the principal amounts of the
notes.

2007.....................................................    102.125%
2008 and thereafter......................................    100.000%
</TABLE>

     In addition, the issuers must pay accrued and unpaid interest on the notes
redeemed.


     Optional Redemption Upon Equity Offerings. At any time, from time to time,
on or prior to February 3, 2003, the issuers may, at their option, use the net
cash proceeds of one or more equity offerings to redeem up to 35% of the
aggregate principal amount of the notes issued under the indenture at a
redemption price equal to 112.75% of the principal amount of the notes plus
accrued and unpaid interest on the notes, if any, to the date of redemption. In
order to do so, the following conditions must be met.


          (1) At least 65% of the aggregate principal amount of notes issued
     under the indenture must remain outstanding immediately after the
     redemption.

          (2) The issuers must make the redemption not more than 60 days after
     the consummation of the equity offering.

     The issuers are not prohibited, however, from acquiring the notes by means
other than a redemption, whether by means of a tender offer or otherwise,
assuming the acquisition of the notes does not otherwise violate any provision
of the indenture.

SELECTION AND NOTICE OF REDEMPTION

     In the event that the issuers choose to redeem less than all of the notes,
selection of the notes for redemption will be made by the trustee either:

          (1) in compliance with the requirements of the principal national
     securities exchange, if any, on which the notes are listed; or,

          (2) on a pro rata basis, by lot or by any method the trustee deems
     fair and appropriate.

     No notes of a principal amount of $1,000 or less shall be redeemed in part.
If a partial redemption is made with the net cash proceeds of an equity
offering, the trustee will select the notes only on a pro rata basis or on as
nearly a pro rata basis as is practicable, subject to DTC procedures. Notice of
redemption will be mailed by first-class mail at least 30 but not more than 60
days before the redemption date to each holder of notes to be redeemed at its
registered address. On and after the redemption date, interest will cease to
accrue on notes or portions of notes called for redemption as long as the
issuers have deposited with the paying agent funds in satisfaction of the
applicable redemption price.

SUBORDINATION

     The payment of all obligations on or relating to the notes is subordinated
in right of payment, to the extent described below and in the indenture, to the
prior payment in full in cash or cash equivalents of all obligations in respect
of senior debt, including with respect to the senior secured credit agreement.
However, payments and distributions made relating to the notes from the trust
described under "-- Legal Defeasance and Covenant Defeasance" shall not be
subordinated in right of payment.

     The holders of senior debt will be entitled to receive payment in full in
cash or cash equivalents of all obligations due in respect of senior debt,
including interest after the commencement of any bankruptcy or other like
proceeding, whether or not the interest is an allowed claim in the proceeding,
before the holders

                                       85
<PAGE>   90

of notes will be entitled to receive any payment or distribution of any kind or
character under the notes. This would apply in the event of any distribution to
creditors of the issuers:

          (1) in a liquidation or dissolution of either issuer;

          (2) in a bankruptcy, reorganization, insolvency, receivership or
     similar proceeding relating to either issuer or its property;

          (3) in an assignment for the benefit of creditors; or

          (4) in any marshaling of either issuer's assets and liabilities.

     The issuers also may not make any payment or distribution of any kind or
character under the notes or acquire any notes for cash or property or otherwise
if:

          (1) a payment default on any senior debt occurs and is continuing; or

          (2) any other default occurs and is continuing on designated senior
     debt that permits holders of the designated senior debt to accelerate its
     maturity and the trustee receives a notice of the default from the
     representative of any designated senior debt. This notice is referred to as
     a payment blockage notice.

     Payments on and distributions with respect to any obligations under the
notes may and shall be resumed:

          (1) in the case of a payment default, upon the date on which the
     default is cured or waived; and

          (2) in case of a nonpayment default, the earliest of:

             - the date on which all nonpayment defaults are cured or waived, so
               long as no other event of default exists,

             - 180 days after the date on which the applicable payment blockage
               notice is received or

             - the date on which the trustee receives notice from the
               representative for the designated senior debt rescinding the
               payment blockage notice, unless the maturity of any designated
               senior debt has been accelerated.

     No new payment blockage notice may be delivered unless and until 360 days
have elapsed since the effectiveness of the immediately prior payment blockage
notice.

     No nonpayment default that existed or was continuing on the date of
delivery of any payment blockage notice to the trustee shall be, or be made, the
basis for a subsequent payment blockage notice unless the default shall have
been cured or waived for a period of not less than 90 consecutive days. However,
any subsequent action, or any breach of any financial covenants for a period
commencing after the date of the initial payment blockage notice shall
constitute a new default for this purpose.

     The issuers must promptly notify holders of senior debt if payment of the
notes is accelerated because of an event of default.

     As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of an issuer, holders of the
notes may recover less ratably than creditors of the issuer who are holders of
senior debt.

     At July 5, 2000, the aggregate amount of senior debt outstanding would have
been $288.6 million, excluding unused commitments of $100.0 million under our
senior credit facilities.

GUARANTEES

     The guarantors will, jointly and severally, unconditionally guarantee the
issuers' obligations under the notes and the indenture. Each guarantee will be
subordinated to the prior payment in full of senior debt of the relevant
guarantor in the same manner and to the same extent that the notes are
subordinated to senior debt. Each guarantee will rank equally with all other
senior subordinated debt of the relevant subsidiary guarantor. A guarantor will
not be permitted to incur indebtedness that is junior in right of payment to
senior indebtedness but senior in right of payment to its guarantee.

     At July 5, 2000:

     - outstanding senior debt of the guarantors would have been $288.6 million;
       and

     - the guarantors would have had no senior subordinated indebtedness other
       than the guarantees.

     Although the indenture limits the amount of indebtedness that the guarantor
subsidiaries may incur, this indebtedness may be substantial and all of it may
be senior debt of the guarantors.

     The obligations of each guarantor under its guarantee will be limited as
necessary to prevent that guarantee from constituting a fraudulent conveyance or
fraudulent transfer under applicable law.

     In the event a guarantor is sold or disposed of, whether by merger,
consolidation, the sale of its capital stock or the sale of all or substantially
all of its assets and whether or not the guarantor is the surviving corporation
in the transaction, to a person which is not Parent, an issuer or a restricted
subsidiary, the guarantor will be released from its obligation under its
guarantee. The guarantor will be released from its guarantee only if, among
other things, the sale or other disposition is in compliance with the indenture,
including the covenants described under "-- Certain Covenants -- Limitation on
Asset Sales" and "-- Certain Covenants -- Merger, Consolidation and Sale of
Assets."

     In addition, a guarantor will be released from its obligations under the
indenture, its guarantee and the registration rights agreement if Parent
designates the subsidiary as an unrestricted subsidiary and the designation
complies with the other applicable provisions of the indenture.

CHANGE OF CONTROL

     Upon the occurrence of a change of control, each holder will have the right
to require that the issuers purchase all or a portion of the holder's notes at a
purchase price equal to 101% of the principal amount of the notes plus accrued
interest to the date of purchase.

     Within 30 days following the date upon which the issuers obtain actual
knowledge that a change of control occurred, the issuers must send, by first
class mail, a notice to each holder, with a copy to the trustee, which notice
shall govern the terms of the change of control offer. The notice shall state,
among other things, the purchase date, which must be no earlier than 30 days nor
later than 45 days from the date the notice is mailed, other than as may be
required by law or stock exchange rule. Holders electing to have a note
purchased in a change of control offer will be required to surrender the note,
with the form entitled "Option of Holder to Elect Purchase" on the reverse of
the note completed, to the paying agent at the address specified in the notice
prior to the close of business on the third business day prior to the purchase
date.

     Prior to the mailing of the notice referred to above, but in any event
within 30 days following the date upon which the issuers obtain actual knowledge
of any change of control, the issuers covenant to:

          (1) repay in full and terminate all commitments under indebtedness
     under the senior secured credit agreement and all other senior debt the
     terms of which require repayment upon a change of control or offer to repay
     in full and terminate all commitments under all indebtedness under the
     senior secured credit agreement and all other senior debt and to repay the
     indebtedness owed to each lender which has accepted the offer; or

                                       87
<PAGE>   92

          (2) obtain the requisite consents under the senior secured credit
     agreement and all other senior debt to permit the repurchase of the notes
     as provided below.

     If the issuers do not first repay their senior debt or obtain the consent
of the lenders of their senior debt as described above, the issuers will be
prohibited from offering to repurchase or repurchasing the notes. The issuers'
failure to comply with the covenant described in the immediately preceding
paragraph may constitute an event of default described in clause (3), but shall
not constitute an event of default described in clause (2), under "Events of
Default" below.

     If a change of control offer is made, there can be no assurance that the
issuers will have available funds sufficient to pay the change of control
purchase price for all the notes that might be delivered by holders seeking to
accept the change of control offer. In the event the issuers are required to
purchase outstanding notes in a change of control offer, the issuers expect that
they would seek third party financing to the extent it does not have available
funds to meet its purchase obligations. However, there can be no assurance that
the issuers would be able to obtain this financing.

     The definition of change of control includes a phrase relating to the sale,
lease, exchange or other transfer of "all or substantially all" of the assets of
NATG and its restricted subsidiaries taken as a whole. Although there is a
developing body of case law interpreting the phrase "substantially all," there
is no precise definition of the phrase under applicable law. Accordingly, in
certain circumstances there may be a degree of uncertainty in ascertaining
whether a particular transaction would involve a disposition of "all or
substantially all" of the assets of NATG and its restricted subsidiaries taken
as a whole, and therefore it may be unclear as to whether a change of control
has occurred and whether the holders have the right to require the issuers to
repurchase the notes.

     Neither the issuers nor the trustee may waive the covenant relating to a
holder's right to redemption upon a change of control. Restrictions in the
indenture described in this prospectus on the ability of Parent and its
restricted subsidiaries to incur additional indebtedness, to grant liens on its
property, to make restricted payments and to make asset sales may also make more
difficult or discourage a takeover, whether favored or opposed by management.
Consummation of any of these transactions in certain circumstances may require
redemption or repurchase of the notes, and there can be no assurance that the
issuers or the acquiring party will have sufficient financial resources to
effect the redemption or repurchase. These restrictions and the restrictions on
transactions with affiliates may, in certain circumstances, make more difficult
or discourage any leveraged buyout of Parent or any of its restricted
subsidiaries by management. While the restrictions cover a wide variety of
arrangements which have traditionally been used to effect highly leveraged
transactions, the indenture may not afford the holders protection in all
circumstances from the adverse aspects of a highly leveraged transaction,
reorganization, restructuring, merger or similar transaction.

     The issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations under the Exchange
Act or other securities laws to the extent those laws and regulations are
applicable in connection with the repurchase of notes in a change of control
offer. To the extent that the provisions of any securities laws or regulations
conflict with the "Change of Control" provisions of the indenture, the issuers
shall comply with the applicable securities laws and regulations and shall not
be deemed to have breached its obligations under the "Change of Control"
provisions of the indenture by virtue of complying with those laws.

CERTAIN COVENANTS

     The indenture contains, among other things, the following covenants:

     Limitation on Restricted Payments. NATG shall not, and shall not permit any
of its restricted subsidiaries to directly or indirectly:

     (1) declare or pay any dividend or make any distribution on or in respect
of shares of NATG's capital stock to holders of its capital stock, other than
dividends or distributions payable in qualified capital stock of NATG,

     (2) purchase, redeem or otherwise acquire or retire for value any capital
stock of NATG or any capital stock of any subsidiary of NATG not held by an
issuer or subsidiary guarantor, or any warrants, rights or options to purchase
or acquire shares of any class of that capital stock, or declare or pay any
dividend, or make any distribution, on or in respect of that capital stock,

     (3) make any principal payment on, purchase, defease, redeem, prepay or
otherwise acquire or retire for value, prior to any scheduled final maturity,
scheduled repayment or scheduled sinking fund payment, any subordinated
indebtedness, or

     (4) make any restricted investment.

     Each of the actions set forth in clauses (1), (2), (3) and (4) above are
referred to as a "restricted payment".

     However, a restricted payment may be made, if at the time of the restricted
payment and immediately after giving effect to the restricted payment,

     (1) no default or event of default has occurred and is continuing,

     (2) NATG is able to incur at least $1.00 of additional indebtedness, other
than permitted indebtedness, in compliance with the covenant described under
"-- Certain Covenants -- Limitation on Incurrence of Additional Indebtedness,"
and

     (3) the aggregate amount of restricted payments, including the proposed
restricted payment, made subsequent to December 31, 1999 shall not exceed the
sum of:

          (a) 50% of the cumulative consolidated net income, or if cumulative
     consolidated net income is a loss, minus 100% of the loss, of NATG earned
     subsequent to December 31, 1999 and through the last day of the fiscal
     quarter ending prior to the date the restricted payment occurs (the
     "Reference Date") treating that period as a single accounting period; plus

          (b) 100% of the aggregate net cash proceeds of, or fair market value
     of property other than cash, determined in good faith by the board of NATG,
     constituting, any equity contribution received by NATG from a holder of
     NATG's capital stock to the extent not required to be used to repay
     indebtedness under the senior secured credit agreement or redeem notes
     under the indenture; plus

          (c) (A) the lesser of:

           - 100% of the aggregate amount of cash and/or fair market value of
             property other than cash, as determined in good faith by the board
             of directors of Parent, received by an issuer or subsidiary
             guarantor from the disposition or sale of any restricted
             investment, other than to a subsidiary of Parent, that was made
             after the original issue date of the notes and

           - the initial amount of that investment; plus

             (B) an amount equal to the net reduction in restricted investments
        in unrestricted subsidiaries of NATG resulting from dividends,
        repayments of loans or advances or other transfers of assets, in each
        case to an issuer or subsidiary guarantor from an unrestricted
        subsidiary; plus

                                       89
<PAGE>   94

                (C) to the extent any unrestricted subsidiary of NATG is
           redesignated as a restricted subsidiary, the lesser of:

                   - the amount of NATG's initial investment in the unrestricted
                     subsidiary and

                   - the fair market value of NATG's Investment in the
                     unrestricted subsidiary as of the date of its
                     redesignation;

        no amount shall be included in this clause (c) to the extent the amount
        is included in consolidated net income of NATG.

     The foregoing provisions in this covenant do not, however, prohibit:

          (1) the payment of any dividend or the consummation of any irrevocable
     redemption within 60 days after the date of declaration of the dividend or
     notice of the redemption if the dividend or redemption would have been
     permitted on the date of declaration or notice;

          (2) the acquisition of any subordinated indebtedness, either:

           - solely in exchange for shares of qualified capital stock of Parent,

           - through the application of net proceeds of a substantially
             concurrent sale for cash, other than to a restricted subsidiary of
             Parent, of shares of qualified capital stock of Parent, or

           - with the net cash proceeds of permitted refinancing indebtedness
             used to refinance the subordinated indebtedness;

          (3) so long as no default or event of default has occurred and is
     continuing, dividends or loans to Parent to enable Parent to repurchase
     junior subordinated notes and/or capital stock of Parent from former or
     current employees, officers, directors or consultants of Parent or any of
     its subsidiaries or their authorized representatives upon the death,
     disability or termination of employment of these persons, in an amount not
     to exceed $2.0 million in any calendar year. NATG may carry over and make
     in a subsequent year, in addition to the amounts permitted for a given
     fiscal year, the amount of dividends or loans permitted to have been made
     but not made in any preceding fiscal year up to a maximum of $10.0 million
     in any fiscal year;

          (4) so long as no default or event of default has occurred and is
     continuing, dividends or loans to Parent not to exceed $100,000 in any
     fiscal year, to enable Parent to make payments to holders of its capital
     stock in lieu of issuance of fractional shares of its capital stock;

          (5) dividends or loans to Parent to enable Parent to repurchase, or
     the repurchase by NATG or a restricted subsidiary of NATG, for cash under
     the put/call agreements, shares of Parent common stock and Parent preferred
     stock issued and outstanding prior to the original issue date of the notes;

          (6) dividends or loans to Parent in an amount not to exceed $250,000
     in any calendar year for the purpose of permitting Parent to pay its
     ordinary operating expenses, including, without limitation, directors'
     fees, indemnification obligations, professional fees and expenses;

          (7) dividends or loans to Parent solely for the purpose of paying
     franchise taxes, federal, state and local income taxes and any related
     interest and penalties, if any, payable by Parent, provided, that any the
     income is attributable to income of NATG and its restricted subsidiaries;
     or

          (8) so long as no default or event of default shall have occurred and
     be continuing or would occur as a consequence of the restricted payment,
     other restricted payments in an aggregate amount not to exceed $7.5 million
     since the original issue date of the notes.

     In determining the aggregate amount of restricted payments made subsequent
to the original issue date of the notes in accordance with clause (3) of the
first paragraph of this covenant, amounts expended under clauses (1), the first
two bullet points of (2), (3), (4) and (6), in each case to the extent not
duplicative of amounts already included.

                                       90
<PAGE>   95

     The amount of all restricted payments other than cash or an investment,
which shall be valued as set forth in the definition of investments, shall be
the fair market value on the date of the restricted payment of the asset(s) or
securities proposed to be transferred or issued to or by NATG or the subsidiary,
as the case may be, in connection with the restricted payment. The fair market
value of any assets or securities that are required to be valued by this
covenant shall be determined by the board of directors of Parent, whose
resolution shall be conclusive. The board of directors' determination must be
based upon an opinion or appraisal issued by an independent financial adviser if
the fair market value exceeds $10.0 million.

     Not later than the date of making any restricted payment, NATG shall
deliver to the trustee an officers' certificate stating that the restricted
payment complies with the indenture and setting forth in reasonable detail the
basis upon which the required calculations were computed. These calculations may
be based upon Parent's latest available internal quarterly financial statements.

     Limitation on Incurrence of Additional Indebtedness. NATG shall not, and
shall not permit any of its restricted subsidiaries to, directly or indirectly,
incur any indebtedness, other than permitted indebtedness. However, if no
default or event of default has occurred and is continuing at the time or as a
consequence of the incurrence of the indebtedness, NATG or any subsidiary
guarantor may incur indebtedness including, without limitation, acquired
indebtedness, if on the date of the incurrence of the indebtedness, after giving
effect to the incurrence of the indebtedness, the consolidated fixed charge
coverage ratio is:

     - greater than 2.0 to 1.0 during the period commencing on the original
issue date of the notes and ending January 31, 2002,

     - 2.25 to 1.0 during the period commencing February 1, 2002 and ending
January 31, 2004, and

     - 2.5 to 1.0 after January 31, 2004.

In addition, NATG shall not, and shall not permit any of its restricted
subsidiaries to, directly or indirectly, incur any contingent obligations in
respect of any junior subordinated notes.

     Limitation on Transactions with Affiliates. NATG shall not, and shall not
permit any of its restricted subsidiaries to, directly or indirectly, enter into
or permit to exist any transaction with or for the benefit of any affiliate
other than:

     (1) affiliate transactions permitted under the following paragraph, and

     (2) affiliate transactions on terms that are no less favorable to NATG or
the restricted subsidiary, as the case may be, than those that might reasonably
have been obtained in a comparable transaction on an arm's-length basis from a
person that is not an affiliate of NATG or the restricted subsidiary.

     All affiliate transactions and each series of related affiliate
transactions that are similar or part of a common plan involving aggregate
payments or other property with a fair market value in excess of $2.5 million
shall be approved by the board of directors of NATG or the restricted
subsidiary, as the case may be. The approval shall be evidenced by a resolution
stating that the board of directors has determined that the transaction complies
with these provisions. If NATG or any restricted subsidiary enters into an
affiliate transaction that involves an aggregate fair market value of more than
$10.0 million, NATG or the restricted subsidiary, as the case may be, shall,
prior to the consummation of the transaction, obtain an opinion that the
affiliate transaction complies with the requirements of this covenant from an
independent financial advisor and file the opinion with the trustee.

     The restrictions set forth in the preceding paragraph shall not apply to:

     (1) reasonable fees and compensation paid to and indemnity provided on
behalf of, officers, directors, employees, agents or consultants of Parent, NATG
or any restricted subsidiaries of NATG as determined in good faith by Parent's
board of directors or senior officers;

     (2) transactions exclusively between or among any of NATG or any restricted
subsidiaries of NATG, provided that the transactions are not otherwise
prohibited by the indenture;

                                       91
<PAGE>   96

     (3) any agreement as in effect as of the original issue date of the notes
or any amendment to those agreements or any transaction contemplated by those
agreements or any replacement agreement so long as any the amendment or
replacement agreement is not more disadvantageous to NATG or its subsidiaries,
as the case may be, in any material respect, than the original agreement as in
effect on the original issue date of the notes;

     (4) restricted payments permitted under the covenant described under
"-- Certain Covenants -- Limitation on Restricted Payments";

     (5) any issuance of securities or other payments, awards or grants in cash,
securities or otherwise under employment arrangements, stock options and stock
ownership plans of Parent entered into in the ordinary course of business and
approved by Parent's board of directors;

     (6) the payment of reasonable and customary management, consulting and
advisory fees and related out of pocket expenses of Willis Stein and its
affiliates, including, without limitation, in connection with acquisitions,
divestitures, or financings by Parent or any of its restricted subsidiaries, in
each case as may be approved by the board of directors of Parent in good faith;

     (7) loans and advances to employees and officers of Parent and its
restricted subsidiaries in the ordinary course of business for bona fide
business purposes not in excess of $1.0 million at any time outstanding;

     (8) indemnification agreements provided for the benefit of Parent or any
restricted subsidiary of Parent from officers, directors, employees agents or
consultants of Parent or any restricted subsidiary of Parent;

     (9) transactions effected as part of a qualified receivables transaction;
and

     (10) the payment to Jack Reich for consulting services under his consulting
agreement with Parent and its subsidiaries as in effect as of the original issue
date of the notes or any amendment to the agreement or any transaction
contemplated by the agreement or in any replacement agreement so long as any
amendment or replacement agreement is not more disadvantageous to Parent or its
subsidiaries, as the case may be, in any material respect than the original
agreement as in effect on the original issue date of the notes.

     Limitation on Liens. NATG shall not, and shall not permit any of its
restricted subsidiaries to, directly or indirectly,

     (1) create, incur, assume or permit to exist any lien on or with respect to
any property or asset of any kind of NATG or any of its restricted subsidiaries,
whether now owned or later acquired, or any income or profits from the property
or assets, or

     (2) file or permit the filing of, or permit to remain in effect, any
financing statement or other similar notice of any lien with respect to the
property, asset, income or profits under the Uniform Commercial Code of any
state or under any similar recording or notice statute, unless,

          (a) in the case of liens securing subordinated indebtedness, the notes
     and guarantees are secured by a lien on the property, assets or proceeds
     that is senior in priority to the liens and

          (b) in all other cases, the notes and guarantees are equally and
     ratably secured.

     Notwithstanding the foregoing, this covenant shall not prohibit or apply to

     - liens securing the senior secured credit agreement;

     - liens securing senior debt and liens securing senior debt of the
       guarantors;

     - liens securing the notes and the guarantees;

     - liens of an issuer or subsidiary guarantor on assets of any other issuer
       or subsidiary guarantor; and

     - permitted liens.

                                       92
<PAGE>   97

     Prohibition on Incurrence of Senior Subordinated Debt. NATG shall not, and
shall not permit any of its restricted subsidiaries to, directly or indirectly,
incur any indebtedness, other than the notes and the guarantees and indebtedness
owed to an issuer or a wholly owned restricted subsidiary of an issuer, that is
by its terms, or by the terms of any agreement governing the indebtedness, is
subordinated in right of payment to any other indebtedness of the person.

     This restriction shall not apply if the indebtedness:

     - is incurred by an issuer or subsidiary guarantor and

     - is by its terms, or by the terms of any agreement governing the
       indebtedness, made expressly subordinate to the obligations of the issuer
       or subsidiary guarantor under the indenture, the notes, in the case of an
       issuer, and the guarantees, in the case of a subsidiary guarantor, to the
       same extent and in the same manner as the obligations are subordinated to
       senior debt.

     Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. NATG shall not, and shall not permit any of its restricted
subsidiaries to, directly or indirectly, create or permit to exist or become
effective any encumbrance or restriction on the ability of any restricted
subsidiary of NATG to:

          (1) pay dividends or make any other distributions on or in respect of
     its capital stock;

          (2) make loans or advances to pay any indebtedness or other obligation
     owed to any issuer or subsidiary guarantor; or

          (3) transfer any of its property or assets to any issuer or subsidiary
     guarantor,

except for any encumbrances or restrictions existing under or by reason of:

          (a) applicable law, regulations or orders of any governmental or
     judicial authority;

          (b) the indenture, the notes, the guarantees, or the senior secured
     credit agreement to the extent incurred in accordance with the indenture;

          (c) customary non-assignment provisions of any contract or any lease
     governing a leasehold interest of NATG or any restricted subsidiary of
     NATG;

          (d) agreements existing on the original issue date of the notes to the
     extent and in the manner those agreements are in effect on the original
     issue date of the notes;

          (e) any restriction or encumbrance on assets being sold that is
     contained in contracts for the sale of assets permitted by the indenture
     pending the close of the sale;

          (f) purchase money obligations for property acquired in the ordinary
     course of business that impose restrictions of the nature described in
     clause (3) above on the property acquired;

          (g) restrictions of the nature described in clause (3) above on the
     transfer of assets subject to any lien permitted under the indenture
     imposed by the holder of the lien;

          (h) any instrument governing indebtedness or capital stock of a person
     acquired by NATG or any of its restricted subsidiaries as in effect at the
     time of the acquisition, except to the extent the indebtedness or capital
     stock was incurred in connection with or in contemplation of the
     acquisition, which encumbrance or restriction is not applicable to any
     person, or the properties or assets of any person, other than the person,
     or the property or assets of the person, so acquired, provided that, in the
     case of indebtedness, the indebtedness was permitted by the terms of the
     indenture to be incurred;

          (i) provisions with respect to the disposition or distribution of
     assets or property in joint venture agreements, asset sale agreements,
     stock sale agreements and other similar agreements entered into in the
     ordinary course of business;

                                       93
<PAGE>   98

          (j) any encumbrance or restriction on a receivables entity effected in
     connection with a qualified receivables transaction;

          (k) restrictions on cash or other deposits or net worth imposed by
     customers under contracts entered into in the ordinary course of business;
     or

          (l) an agreement governing indebtedness incurred to refinance the
     indebtedness issued, assumed or incurred under an agreement referred to in
     clause (b) or (d) above. The provisions relating to the encumbrance or
     restriction contained in the indebtedness must be no less favorable to the
     issuers or subsidiary guarantors in any material respect as determined by
     the board of directors of Parent in its reasonable and good faith judgment
     than the provisions relating to the encumbrance or restriction contained in
     agreements referred to in clause (b) or (d) above.

     Merger, Consolidation and Sale of Assets. No issuer shall, in a single
transaction or series of related transactions, consolidate or merge with or into
any person, or sell, assign, transfer, lease, convey or otherwise dispose of, or
cause or permit any restricted subsidiary of the issuer to sell, assign,
transfer, lease, convey or otherwise dispose of, all or substantially all of the
assets of the issuer and its restricted subsidiaries, determined on a
consolidated basis for the issuer and its restricted subsidiaries, whether as an
entirety or substantially as an entirety to any person. This restriction shall
not apply if:

          (1) either

        - the issuer shall be the surviving or continuing corporation, or

        - the surviving entity, if other than the issuer, (a) shall be a
          corporation, partnership, trust or a limited liability company
          organized and validly existing under the laws of the United States or
          any state thereof or the District of Columbia and (b) shall expressly
          assume, by supplemental indenture, executed and delivered to the
          trustee, the due and punctual payment of the principal of, and
          premium, if any, and interest on all of the notes and the performance
          of every covenant of the notes, this indenture and the registration
          rights agreement on the part of the issuer to be performed or
          observed;

          (2) immediately after giving effect to the transaction and the
     assumption contemplated by clause (1)(b) above, including giving effect to
     any indebtedness and acquired indebtedness incurred or anticipated to be
     incurred in connection with the transaction, the issuer or the surviving
     entity, as the case may be, shall be able to incur at least $1.00 of
     additional indebtedness, other than permitted indebtedness, in compliance
     with the covenant described under "-- Certain Covenants -- Limitation on
     Incurrence of Additional Indebtedness";

          (3) immediately before and immediately after giving effect to the
     transaction and the assumption contemplated by clause (1)(b) above,
     including, without limitation, giving effect to any indebtedness and
     acquired indebtedness incurred or anticipated to be incurred and any lien
     granted in connection with the transaction, no default or event of default
     shall have occurred or be continuing; and

          (4) the issuer or surviving entity, as the case may be, shall have
     delivered to the trustee an officers' certificate and an opinion of
     counsel, each stating that the consolidation, merger, sale, assignment,
     transfer, lease, conveyance or other disposition and, if a supplemental
     indenture is required in connection with the transaction, the supplemental
     indenture comply with the applicable provisions of this indenture and that
     all conditions precedent in the indenture relating to the transaction have
     been satisfied.

The indenture does not prohibit the merger of an issuer with an affiliate
incorporated solely for the purpose of reincorporating or similarly reorganizing
in another jurisdiction.

     For purposes of the immediately preceding paragraph, the transfer of all or
substantially all of the properties or assets of one or more restricted
subsidiaries of an issuer the capital stock of which constitutes

                                       94
<PAGE>   99

all or substantially all of the properties and assets of the issuer, shall be
deemed to be the transfer of all or substantially all of the properties and
assets of the issuer.

     Each guarantor, other than any guarantor whose guarantee is to be released
in accordance with the terms of the guarantee and the indenture in connection
with any transaction complying with the provisions of the covenant described
under "-- Certain Covenants -- Limitation on Asset Sales", shall not, and NATG
shall not cause or permit any guarantor to, consolidate with or merge with or
into any person. This restriction shall not apply if:

     (1) the entity formed by or surviving any the consolidation or merger, if
other than the guarantor, is a corporation, partnership, trust or limited
liability company organized and existing under the laws of the United States or
any state of the United States or the District of Columbia;

     (2) the entity assumes by supplemental indenture all of the obligations of
the guarantor under the indenture and on its guarantee;

     (3) immediately after giving effect to the transaction, no default or event
of default shall have occurred and be continuing; and

     (4) immediately after giving effect to the transaction and the use of any
net proceeds from the transaction on a pro forma basis, Parent could satisfy the
provisions of clause (2) of the first paragraph of this covenant.

     Any merger or consolidation of a guarantor with and into an issuer, with
the issuer being the surviving entity, or a guarantor that is a wholly owned
subsidiary of an issuer need only comply with clause (4) of the first paragraph
of this covenant.

     Notwithstanding anything to the contrary in this covenant, no transaction
shall be permitted under this covenant unless after giving effect to the
transaction, there shall be a co-issuer of the notes that is a corporation
organized and existing under the laws of the United States or any state of the
United States or the District of Columbia.

     Upon any consolidation, combination or merger or any transfer of all or
substantially all of the assets of an issuer in accordance with this covenant in
which the issuer is not the surviving entity, the surviving entity shall succeed
to, and be substituted for, and may exercise every right and power of, the
issuer under the indenture and the notes with the same effect as if the
surviving entity had been named as an issuer.

     Limitation on Asset Sales. NATG shall not, and shall not permit any of its
restricted subsidiaries to, consummate an asset sale, unless

     (1) NATG or the applicable restricted subsidiary, as the case may be,
receives consideration at the time of the asset sale which, taken as a whole, is
at least equal to the fair market value of the assets sold or otherwise disposed
of, as determined in good faith, by Parent's board of directors;

     (2) at least 75% of the consideration received by the issuers or the
restricted subsidiary, as the case may be, from the asset sale is received at
the time of the disposition and consists of one of the following:

     - cash or cash equivalents;

     - any liabilities, as shown on NATG's or the restricted subsidiary's most
recent balance sheet, of NATG or the restricted subsidiary, other than
liabilities that are by their terms subordinated to the notes, that are assumed
by the transferee of the assets,

     - any securities, notes or other obligations received by NATG or the
subsidiary from the transferee that are converted by NATG or the subsidiary into
cash within 180 days after the asset sale, to the extent of the cash received;
and

     - any combination of the foregoing.

                                       95
<PAGE>   100

     (3) upon the consummation of an asset sale, NATG shall apply, or cause its
restricted subsidiary to apply, the net cash proceeds relating to the asset sale
within 365 days of receipt of the net cash proceeds either:

     - to prepay any senior debt and, in the case of any senior debt under any
revolving credit facility, effect a permanent reduction in the availability
under the revolving credit facility. The permanent reduction in availability
need not be made prior to December 15, 2001 to the extent that the senior debt
being repaid had been borrowed under the acquisition subfacility of the
revolving credit facility under the senior secured credit agreement

     - to invest in or to acquire other properties and assets that replace the
properties and assets that were the subject of the asset sale or in properties
and assets that will be used or useful in a permitted business ("replacement
assets") and/or

     - to acquire all or substantially all of the assets of, or all of the
voting stock of, another person engaged in a permitted business. If voting stock
is acquired, the person must become a subsidiary guarantor.

NATG may not sell or otherwise dispose of any capital stock of the Orius Capital
except in compliance with the covenant described under "-- Certain
Covenants -- Merger, Consolidation and Sale of Assets."

     Pending the final application of any net cash proceeds, NATG or the
restricted subsidiary may temporarily reduce revolving credit borrowings or
otherwise invest the net cash proceeds in any manner that is not otherwise
prohibited by the indenture. On the 366th day after an asset sale or the earlier
date, if any, on which the senior management or board of directors, as the case
may be, of NATG or the restricted subsidiary determines not to apply the net
cash proceeds relating to the asset sale as set forth in clause (3) of the
preceding paragraph (each, a "net proceeds offer trigger date"), the aggregate
amount of net cash proceeds which has not been applied on or before the net
proceeds offer trigger date as permitted in clause (3) of the next preceding
sentence (each a "Net Proceeds Offer Amount") shall be applied by NATG or the
restricted subsidiary to make a net proceeds offer". The net proceeds offer
shall be on a date not less than 30 nor more than 60 days following the
applicable net proceeds offer trigger date, from all holders on a pro rata
basis, that principal amount of notes equal to the net proceeds offer amount at
a price equal to 100% of the principal amount of the notes to be purchased, plus
accrued and unpaid interest on the notes, if any, to the date of purchase.

     If at any time any non-cash consideration received by NATG or the
restricted subsidiary, as the case may be, in connection with any asset sale is
converted into or sold or otherwise disposed of for cash, other than interest
received with respect to any non-cash consideration, then the conversion or
disposition shall be deemed to constitute an asset sale under the indenture and
the net cash proceeds of the asset sale shall be applied in accordance with this
covenant.

     The issuers may defer the net proceeds offer until there is an aggregate
unutilized net proceeds offer amount equal to or in excess of $10.0 million
resulting from one or more asset sales, at which time, the entire unutilized net
proceeds offer amount, and not just the amount in excess of $10.0 million, shall
be applied as provided in this paragraph.

     In the event of the transfer of substantially all, but not all, of the
property and assets of NATG and its restricted subsidiaries as an entirety to a
person in a transaction permitted under the covenant described under "-- Certain
Covenants -- Merger, Consolidation and Sale of Assets," the successor
corporation shall be deemed to have sold the properties and assets of NATG and
its subsidiaries not so transferred for purposes of this covenant, and shall
comply with the provisions of this covenant with respect to the deemed sale as
if it were an asset sale. In addition, the fair market value of the properties
and assets of NATG or the subsidiaries deemed to be sold under the terms of this
paragraph less the fair market value of all liabilities of the person related to
the property and assets not transferred shall be deemed to be net cash proceeds
for purposes of this covenant.

                                       96
<PAGE>   101

     NATG and its restricted subsidiaries will be permitted to consummate an
asset sale without complying with the provisions of this covenant to the extent
that:

     (1) at least 75% of the consideration for the asset sale constitutes
replacement assets; and

     (2) the asset sale is for fair market value as determined in good faith by
the board of directors of Parent.

Any consideration not constituting replacement assets received by NATG or any of
its restricted subsidiaries in connection with any asset sale permitted to be
consummated under this clause shall constitute net cash proceeds subject to the
provisions of this covenant.

     Notice of each net proceeds offer shall be mailed or caused to be mailed,
by first class mail, by NATG or the relevant subsidiary within 30 days following
the applicable net proceeds offer trigger date to all holders of notes at their
last registered addresses, with a copy to the trustee. A net proceeds offer
shall remain open for a period of 20 business days or a longer period as may be
required by law. The notice shall contain all instructions and materials
necessary to enable the holders to tender notes in the net proceeds offer and
shall comply with the procedures set forth in the indenture. To the extent that
the aggregate amount of notes tendered is less than the net proceeds offer
amount, NATG or the relevant restricted subsidiary may use the remaining net
proceeds offer amount for general corporate purposes or for any other purpose
not prohibited by the indenture, and any remaining net cash proceeds then be
deemed not to constitute net cash proceeds.

     NATG and its restricted subsidiaries intend to comply with the requirements
of Rule 14e-1 under the Exchange Act to the extent those laws and regulations
are applicable in connection with the repurchase of notes as part of a net
proceeds offer. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this covenant, NATG and its
restricted subsidiaries shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached their obligations under
this covenant by virtue of their compliance with those laws.

     The agreements governing the issuers' outstanding senior debt currently
prohibit the issuers from purchasing any notes, and also provide that specified
change of control or asset sale events would constitute a default under those
agreements. Any future credit agreements or other agreements relating to senior
debt to which the issuers become parties may contain similar restrictions and
provisions. In the event a change of control or asset sale occurs at a time when
the issuers are prohibited from purchasing notes, the issuers could seek the
consent of their senior lenders to the purchase of notes or could attempt to
refinance the borrowings that contain the prohibition. If the issuers do not
obtain the necessary consent or repay the borrowings, the issuers would be
prohibited from purchasing the notes. In that case, the issuers' failure to
purchase tendered notes would constitute an event of default under the indenture
which would, in turn, constitute a default under the senior debt. In these
circumstances, the subordination provisions in the indenture would likely
restrict payments to the holders of notes.

     Conduct of Business. NATG shall not, and shall not permit any of its
restricted subsidiaries to, engage in any business other than permitted
businesses.

     Orius Capital shall engage in no business other than the issuance of the
notes. Orius Capital may only engage in those activities that are incidental to:

     - the maintenance of is corporate existence in compliance with applicable
       law,

     - legal, tax and accounting matters in connection with any of the foregoing
       activities and

     - entering into, and performing its obligations under, the documents to
       which it is a party.

                                       97
<PAGE>   102

     Reports to Holders. Whether or not required by the rules and regulations of
the SEC, so long as any notes are outstanding, Parent and the issuers shall
furnish the holders of notes:

     (1) all quarterly and annual financial information that would be required
to be contained in a filing with the SEC on Forms 10-Q and 10-K if Parent or the
issuers were required to file those Forms, including a "Management's Discussion
and Analysis of Financial Condition and Results of Operations" that describes
the financial condition and results of operations of Parent and its consolidated
subsidiaries. If Parent shall cease to own more than a majority of the voting
securities of NATG, of NATG and its consolidated subsidiaries, Parent's
financial statements shall show, in reasonable detail, either on the face of the
financial statements or in the related footnotes, the information required to be
presented for the issuers and the guarantors under Staff Accounting Bulletin 53
or any successor interpretation or rule of the SEC,

     (2) with respect to the annual information only, a report by the certified
independent accountants of Parent and its consolidated subsidiaries, or, if
Parent shall cease to own more than a majority of the voting securities of NATG,
of NATG and its consolidated subsidiaries, in each case, within five days after
the time specified in the rules and regulations of the SEC;

     (3) all current reports that would be required to be filed with the SEC on
Form 8-K if Parent or the issuers were required to file those reports, in each
case within two days after the time periods specified in the SEC's rules and
regulations.

     Following the consummation of the exchange offer, whether or not required
by the rules and regulations of the SEC, Parent or NATG will file a copy of all
of the above information and reports with the SEC for public availability within
the time periods specified in the SEC's rules and regulations, unless the SEC
will not accept the filing. Parent or NATG will make the information available
to securities analysts and prospective investors upon request. In addition, for
so long as any notes remain outstanding, NATG shall furnish to the holders and
to securities analysts and prospective investors, upon their request, the
information required to be delivered under Rule 144A(d)(4) under the Securities
Act. Parent and the issuers will also comply with the other provisions of TIA
sec. 314(a).

     Additional Subsidiary Guarantees. NATG will cause any subsidiary of NATG
that after the original issue date of the notes first becomes a guarantor of an
issuer's obligations under the senior secured credit agreement to, within 10
days of the date on which it became a guarantor:

     (1) execute and deliver to the trustee a supplemental indenture under which
the subsidiary shall unconditionally guarantee all of the issuers' obligations
under the notes and the indenture on the terms set forth in the indenture; and

     (2) deliver to the trustee an opinion of counsel that the supplemental
indenture has been duly authorized, executed and delivered by the subsidiary and
constitutes a legal, valid, binding and enforceable obligation of the
subsidiary.

After these conditions are satisfied, the subsidiary shall be a guarantor for
all purposes of the indenture.

     In the event that the senior secured credit agreement shall no longer be in
effect, NATG shall cause any domestic restricted subsidiary of NATG, other than
a receivables entity or a restricted subsidiary that is already a guarantor, to
promptly:

     (1) execute and deliver to the trustee a supplemental indenture under which
the subsidiary shall unconditionally guarantee all of the issuers' obligations
under the notes and the indenture on the terms set forth in the indenture; and

     (2) deliver to the trustee an opinion of counsel that the supplemental
indenture has been duly authorized, executed and delivered by the subsidiary and
constitutes a legal, valid, binding and enforceable obligation of the
subsidiary.

After these conditions are satisfied, the subsidiary shall be a guarantor for
all purposes of the indenture.

                                       98
<PAGE>   103

     Payments for Consent NATG will not, and will not permit any of its
subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any holder of notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of the indenture or the notes unless the consideration is offered to be paid and
is paid to all holders of the notes that consent within the time frame set forth
in the relevant solicitation documents.

     Disposal of Subsidiary Stock. Except for any sale of 100% of the capital
stock or other equity securities of a restricted subsidiary effected in
compliance with the covenants described under "-- Certain
Covenants -- Limitation on Restricted Payments" and "-- Certain
Covenants -- Merger, Consolidation and Sale of Assets," NATG will not, and will
not permit any of its restricted subsidiaries to, directly or indirectly sell,

          (1) to qualify directors if required by applicable law,

          (2) to an issuer or subsidiary guarantor, and

          (3) liens in favor of the lenders under the senior secured credit
     agreement.

EVENTS OF DEFAULT

     The following events are defined in the indenture as "events of default":

     (1) the failure to pay interest on any notes when the interest becomes due
and payable and the default continues for a period of 30 days, whether or not
the payment is prohibited by the subordination provisions of the indenture;

     (2) the failure to pay the principal on any notes, when the principal
becomes due and payable, at maturity, upon redemption or otherwise, including
the failure to make a payment to purchase notes tendered pursuant to a change of
control offer or a net proceeds offer or a mandatory redemption, whether or not
the payment is prohibited by the subordination provisions of the indenture;

     (3) a default in the observance or performance of any other covenant or
agreement contained in the indenture which default continues for a period of 30
days after the issuers receive written notice specifying the default and
demanding that the default be remedied from the trustee or the holders of at
least 25% of the outstanding principal amount of the notes;

     (4) the failure to pay at final stated maturity, giving effect to any
applicable grace periods and any extensions of the maturity date, the principal
amount of any indebtedness of NATG or any restricted subsidiary of NATG or the
acceleration of the final stated maturity of the indebtedness if the aggregate
principal amount of the indebtedness, together with the principal amount of any
other indebtedness in default for failure to pay principal at final maturity or
which has been accelerated, aggregates $10.0 million or more at any time. NATG
or its restricted subsidiary shall have a 20-day grace period to cure this
default;

     (5) one or more judgments in an aggregate amount in excess of $10.0 million
shall have been rendered against NATG or any of its significant subsidiaries and
the judgments remain undischarged, unpaid or unstayed for a period of 60 days
after the judgment or judgments become final and non-appealable;

     (6) specified events of bankruptcy affecting Parent, an issuer or any of
their Significant Subsidiaries; or

     (7) (a) any guarantee or any provision of any guarantee shall cease to be
in full force or effect, other than in accordance with its express terms, or (b)
Parent or any other guarantor or any person acting by or on behalf of the
guarantor shall deny or disaffirm the guarantor's obligations under its
guarantee, or (c) Parent or any other guarantor shall default in the due
performance or observance of any term,

                                       99
<PAGE>   104

covenant or agreement on its part to be performed or observed, after giving
effect to any applicable grace periods, as provided in its guarantee.

     If an event of default, other than an event of default specified in clause
(6) above with respect to an issuer, shall occur and be continuing, the trustee
or the holders of at least 25% in principal amount of the notes then outstanding
may declare the principal of and accrued interest on all the notes to be due and
payable by notice in writing to the issuers and the trustee specifying the
respective event of default and that it is a "notice of acceleration". Principle
and accrued interest on the notes:

     (1) shall become immediately due and payable; or

     (2) if there are any amounts outstanding under the senior secured credit
agreement, shall become immediately due and payable upon the first to occur of
an acceleration under the senior secured credit agreement or 5 business days
after receipt by the issuers and the representative under the senior secured
credit agreement of the acceleration notice but only if the event of default is
then continuing.

     If an event of default specified in clause (6) above with respect to an
issuer occurs and is continuing, then all unpaid principal of, and premium, if
any, and accrued and unpaid interest on all of the outstanding notes shall
become and be immediately due and payable without any declaration or other act
on the part of the trustee or any holder.

     The indenture provides that, at any time after a declaration of
acceleration of the notes, the holders of a majority in principal amount of the
notes may rescind and cancel the declaration and its consequences:

     (1) if the rescission would not conflict with any judgment or decree;

     (2) if all existing events of default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration;

     (3) to the extent the payment of interest is lawful, interest on overdue
installments of interest and overdue principal, which has become due otherwise
than by the declaration of acceleration, has been paid;

     (4) if the issuers have paid the trustee its reasonable compensation and
reimbursed the trustee for its expenses, disbursements and advances; and

     (5) in the event of the cure or waiver of an event of default of the type
described in clause (6) of the description above of events of default, the
trustee shall have received an officers' certificate to the effect that the
event of default has been cured or waived. No rescission shall affect any
subsequent default or impair any right consequent to any subsequent default.

     The holders of a majority in principal amount of the notes may waive any
existing default or event of default under the indenture, and its consequences,
except a default in the payment of the principal of or interest on any notes.

     Holders of the notes may not enforce the indenture or the notes except as
provided in the indenture and under the TIA. Subject to the provisions of the
indenture relating to the duties of the trustee, the trustee is under no
obligation to exercise any of its rights or powers under the indenture at the
request, order or direction of any of the holders, unless the holders have
offered to the trustee reasonable indemnity. Subject to all provisions of the
indenture and applicable law, the holders of a majority in aggregate principal
amount of the then outstanding notes have the right to 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.

     Under the indenture, Parent and the issuers are required to provide
officers' certificates to the trustee promptly upon any officer obtaining
knowledge of any default or event of default that has occurred and, if
applicable, describe the default or event of default and its status. In
addition, Parent and the issuers are required to provide this certification at
least annually whether or not they know of any default or event of default.

                                       100
<PAGE>   105

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     A director, officer, employee, member, stockholder or incorporator, as
such, of Parent or any of its subsidiaries shall not have any liability for any
obligations of the issuers in connection with the notes. However, this shall in
no way limit the obligations of any guarantor in respect of the guarantees. Each
holder by accepting a note waives and releases this liability, and this waiver
and release are part of the consideration for the issuance of the notes.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     The issuers may, at their option and at any time, elect to have their
obligations and the obligations of the guarantors discharged with respect to the
outstanding notes and guarantees. This is called legal defeasance. Legal
defeasance means that the issuers shall be deemed to have paid and discharged
the entire indebtedness represented by the outstanding notes, except for:

     (1) their obligations with respect to the notes concerning issuing
temporary notes, registration of notes, mutilated, destroyed, lost or stolen
notes and the maintenance of an office or agency for payments;

     (2) the rights, powers, trust, duties and immunities of the trustee and the
issuers' obligations in connection with those rights, powers, trust, duties and
immunities; and

     (3) the legal defeasance provisions of the indenture.

     In addition, the issuers may, at their option and at any time, elect to
have the obligations of the issuers released with respect to specified covenants
that are described in the indenture. This is called covenant defeasance. After
the covenant defeasance, any omission to comply with those covenants shall not
constitute a default or event of default under the notes. In the event covenant
defeasance occurs, certain events, not including non-payment, bankruptcy,
receivership, reorganization and insolvency event, described under "Events of
Default" will no longer constitute an event of default with respect to the
notes.

     In order to exercise either legal defeasance or covenant defeasance:

     (1) the issuers must irrevocably deposit with the trustee, in trust, for
the benefit of the holders cash in U.S. dollars, non-callable U.S. government
obligations, or a combination of the two, in an amount as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest on the notes on the
stated date for payment or on the applicable redemption date, as the case may
be;

     (2) in the case of legal defeasance, each issuer shall have delivered to
the trustee an opinion of counsel in the United States reasonably acceptable to
the trustee confirming that:

          (a) the issuers have received from, or there has been published by,
     the Internal Revenue Service a ruling; or

          (b) since the date of the indenture, there has been a change in the
     applicable federal income tax law,

     in either case to the effect that, and the opinion of counsel shall confirm
that, the holders will not recognize income, gain or loss for federal income tax
purposes as a result of the legal defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if the legal defeasance had not occurred;

     (3) in the case of covenant defeasance, each issuer shall have delivered to
the trustee an opinion of counsel in the United States reasonably acceptable to
the trustee confirming that the holders will not recognize income, gain or loss
for federal income tax purposes as a result of the covenant defeasance and will
be subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if the covenant defeasance had not
occurred;

                                       101
<PAGE>   106

     (4) no default or event of default shall have occurred and be continuing on
the date of the deposit, other than a default or event of default under the
indenture resulting from the incurrence of indebtedness, all or a portion of
which will be used to defease the notes concurrently with the incurrence;

     (5) the legal defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under the indenture, other than
a default or event of default under the indenture resulting from the incurrence
of indebtedness, all or a portion of which will be used to defease the notes
concurrently with the incurrence, or any other material agreement or instrument
to which Parent or any of its restricted subsidiaries is a party or by which
Parent or any of its restricted subsidiaries is bound;

     (6) each issuer shall have delivered to the trustee an officers'
certificate stating that the deposit was not made by the issuers with the intent
of preferring the holders over any other creditors of the issuers or with the
intent of defeating, hindering, delaying or defrauding any other creditors of
the issuers or others;

     (7) each issuer shall have delivered to the trustee an officers'
certificate and an opinion of counsel, each stating that all conditions
precedent relating to the legal defeasance or the covenant defeasance have been
complied with;

     (8) each issuer shall have delivered to the trustee an opinion of counsel
to the effect that:

          (a) the trust funds will not be subject to any rights of holders of
     senior debt or guarantor senior debt, including, without limitation, those
     arising under the indenture; and

          (b) assuming no intervening bankruptcy of an issuer between the date
     of deposit and the 91st day following the date of deposit and that no
     holder is an insider of an issuer, after the 91st day following the date of
     deposit, the trust funds will not be subject to the effect of any
     applicable bankruptcy, insolvency, reorganization or similar laws affecting
     creditors' rights generally; and

     (9) specified other customary conditions precedent are satisfied.

     The opinion of counsel required by clause (2) above concerning legal
defeasance need not be delivered if all notes not previously delivered to the
trustee for cancellation (1) have become due and payable or (2) will become due
and payable on the maturity date within one year under arrangements satisfactory
to the trustee for the giving of notice of redemption by the trustee in the
name, and at the expense, of the issuers.

SATISFACTION AND DISCHARGE

     The indenture will be discharged and will cease to be of further effect,
except as to surviving rights or registration of transfer or exchange of the
notes, as expressly provided for in the indenture as to all outstanding notes
when:

     (1) either:

          (a) all the notes authenticated and delivered have been delivered to
     the trustee for cancellation; or

          (b) all notes not previously delivered to the trustee for cancellation
     have become due and payable and the issuers shall have irrevocably
     deposited or caused to be deposited with the trustee funds in an amount
     sufficient to pay principal of, premium, if any, and interest on the
     outstanding notes not previously delivered to the trustee for cancellation,
     to the date of deposit together with irrevocable instructions from the
     issuers directing the trustee to apply the funds to the payment of the
     notes at maturity or redemption, as the case may be;

     (2) the issuers have paid all other sums payable under the indenture by
them; and

                                       102
<PAGE>   107

     (3) each issuer has delivered to the trustee an officers' certificate and
an opinion of counsel stating that all conditions precedent under the indenture
relating to the satisfaction and discharge of the indenture have been complied
with.

MODIFICATION OF THE INDENTURE

     From time to time, the issuers, the guarantors and the trustee, without the
consent of the holders, may amend the indenture for certain specified purposes,
including curing ambiguities, defects or inconsistencies, so long as the change
does not, in the opinion of the trustee, adversely affect the rights of any of
the holders in any material respect. In formulating its opinion on those
matters, the trustee will be entitled to rely on evidence as it deems
appropriate, including, without limitation, only on an opinion of counsel and an
officers' certificate. Other modifications and amendments of the indenture may
be made with the consent of the holders of a majority in principal amount of the
then outstanding notes issued under the indenture, except that, without the
consent of each holder affected, no amendment may:

     (1) reduce the amount of notes whose holders must consent to an amendment,
supplement or waiver;

     (2) reduce the rate of or change or have the effect of changing the time
for payment of interest, including defaulted interest, on any notes;

     (3) reduce the principal of or change or have the effect of changing the
fixed maturity of any notes, or change the date on which any notes may be
subject to redemption or reduce the redemption or purchase price of the notes;

     (4) make any notes payable in money other than that stated in the notes;

     (5) make any change in provisions of the indenture protecting the right of
each holder to receive payment of principal of and interest on the notes on or
after the due date of the notes or to bring suit to enforce payment on the
notes;

     (6) modify or change any provision of the indenture or the related
definitions affecting the subordination or ranking of the notes or any guarantee
in a manner which adversely affects the holders; or

     (7) release Parent or any guarantor that is a significant subsidiary of
Parent or an issuer from any of its obligations under its guarantee or the
indenture otherwise than in accordance with the terms of the indenture.

GOVERNING LAW

     The indenture provides that it, the notes and any guarantees will be
governed by, and construed in accordance with, the laws of the state of New York
but without giving effect to applicable principles of conflicts of law to the
extent that the application of these principles would require that the law of
another jurisdiction be applied.

THE TRUSTEE

     The indenture provides that, except during the continuance of an event of
default, the trustee will perform only those duties as are specifically set
forth in the indenture or the TIA. During the existence of an event of default,
the trustee will exercise the rights and powers vested in it by the indenture,
and use the same degree of care and skill in its exercise as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

     The indenture and the provisions of the TIA contain limitations on the
rights of the trustee, should it become a creditor of an issuer, to obtain
payments of claims in some cases or to realize on property received in respect
of any claim as security or otherwise. Subject to the TIA, the trustee will be
permitted to engage in other transactions. If the trustee acquires any
conflicting interest as described in the TIA, it must eliminate the conflict or
resign.

     "consolidated fixed charge coverage ratio" shall mean the ratio of
consolidated EBITDA of NATG during the four full fiscal quarters for which
internal financial statements are available ending on or prior to the date of
the transaction giving rise to the need to calculate the consolidated fixed

     For purposes of this definition, "consolidated EBITDA" and "consolidated
fixed charges" shall be calculated after giving effect on a pro forma basis for
the period of the calculation to

        (1) (a) the incurrence or repayment of any indebtedness of NATG or any
        of its restricted subsidiaries giving rise to the need to make the
        calculation, and the application of the proceeds from the incurrence or
        repayment, and

        occurring during the four quarter period or at any time subsequent to

        transaction date, as if the incurrence or repayment, as the case may be,
        and the application of the proceeds from the incurrence or repayment,
        occurred on the first day of the four quarter period, and

                                       107
<PAGE>   112

        calculated on a pro forma basis with respect to the asset acquisition
        taking into account the pro forma adjustments, if any, resulting from
        the asset acquisitions, attributable to the assets which are the subject
        of the asset acquisition or asset sale during the four quarter period or
        at any time subsequent to the four quarter period,

        occurring during the four quarter period or at any time subsequent to
        the last day of the four quarter period and on or prior to the date of
        the transaction giving rise to the need to make the calculation , as if
        the asset sale or other disposition or asset acquisition, including any
        related incurrence of indebtedness, occurred on the first day of the
        four quarter period.

     If NATG or any of its restricted subsidiaries directly or indirectly
guarantees indebtedness of a third person, the preceding sentence shall give
effect to the incurrence of the guaranteed indebtedness as if NATG or the
restricted subsidiary had directly incurred or otherwise assumed the guaranteed
indebtedness, calculated to avoid duplication. In calculating "consolidated
fixed charges" for purposes of determining the denominator, but not the
numerator, of the "consolidated fixed charge coverage ratio,"

     (1) interest on outstanding indebtedness, determined on a fluctuating basis
as of the date of the transaction giving rise to the need to make the
calculation and which will continue to be so determined of that date, shall be
deemed to have accrued at a fixed rate per annum equal to the rate of interest
on the indebtedness in effect on that date;

     (2) if interest on any indebtedness actually incurred on the date of the
transaction giving rise to the need to make the calculation may optionally be
determined at an interest rate based upon a factor of a prime or similar rate, a
eurocurrency interbank offered rate, or other rates, then the interest rate in
effect on that date will be deemed to have been in effect during the four
quarter period; and

     (3) notwithstanding clause (1) above, interest on indebtedness determined
on a fluctuating basis, to the extent the interest is covered by interest rate
agreements relating to the indebtedness, shall be deemed to accrue at the rate
per annum resulting after giving effect to the operation of those agreements.

     (2) to the extent not included in consolidated interest expense, the
product of

          (a) the amount of all dividend payments on any series of capital stock
     of that person, other than dividends paid in qualified capital stock, paid
     in cash during that period, times

     "consolidated interest expense" shall mean, with respect to any person for
any period, the sum of, without duplication:

          (d) the interest portion of any deferred payment obligation; and

<PAGE>   113

     (2) the interest component of capitalized lease obligations paid, accrued
and/or scheduled to be paid or accrued by that person and its restricted
subsidiaries during the period as determined on a consolidated basis in

the person, in which any other person, other than the first person or any of its
restricted subsidiaries, has a joint interest, except to the extent of the
amount of dividends or other distributions actually paid to the first person or
any of its restricted subsidiaries by the second person during the period,

     (2) the income or loss of any other person accrued prior to the date it
becomes a restricted subsidiary of the first person or is merged into or

of its charter or any agreement, instrument, judgment, decree, order, statute,
rule or governmental regulation applicable to that restricted subsidiary,

     (4) any after-tax gains or losses attributable to asset sales, without
regard to the $1.0 million limitation set forth in the definition of asset
sales, and

     (5) to the extent not included in clauses (1) through (4) above, any net
non-cash extraordinary gains or net noncash extraordinary losses.

incurred in connection with the consummation of any asset acquisition in an

restricted subsidiary only if

          (1) immediately after giving effect to the designation, Parent would
     be able to incur at least $1.00 of additional indebtedness, other than
     permitted indebtedness, in compliance with the covenant described under
     "-- Certain Covenants -- Limitation on Incurrence of Additional
     Indebtedness," and

          (2) immediately before and immediately after giving effect to the
     designation, no default or event of default shall have occurred and be

     "U.S. legal tender" means the coin or currency of the United States of
America as at the time of payment shall be legal tender for the payment of
public and private debts.

     "voting securities" means any class of capital stock of a person pursuant
to which the holders of the capital stock have, at the time of determination,

voting power by reason of the happening of any contingency.

     "weighted average life to maturity" means, when applied to any indebtedness

     (1) the then outstanding aggregate principal amount of the indebtedness
into

<PAGE>   128

     (2) the sum of the total of the products obtained by multiplying (a) the
amount of each then remaining installment, sinking fund, serial maturity, or
other required payment of principal, including payment at final maturity, in

subsidiary of that person, which at the time of determination is a restricted
subsidiary of that person.

                         BOOK-ENTRY; DELIVERY AND FORM

THE GLOBAL NOTES

     Rule 144A Global Note. Notes that were offered and sold to QIBs under Rule
144A were issued in the form of one or more registered notes in global form,
without interest coupons (collectively, the "Rule 144A Global Note"). The Rule
144A Global Note was deposited on the original issue date of the notes with DTC
and was registered in the name of Cede & Co., as nominee of DTC, or are in the
custody of the trustee under the FAST Balance Certificate Agreement between DTC
and the trustee. Interests in the Rule 144A Global Note were available for
purchase only by QIBs.

     Regulation S Global Notes. Notes offered and sold in offshore transactions
to Non-U.S. Persons in reliance on Regulation S were issued in the form of one
or more registered notes in global form, without interest coupons (collectively,
the "Regulation Global Note"). The Regulation S Global Note is deposited with,
or on behalf of, a custodian for DTC in the manner described in the preceding
paragraph for credit to the respective accounts of the purchasers or to other
accounts as they may have directed at Morgan Guaranty Trust Company of New York,
Brussels Office, as operator of the Euroclear System "Euroclear", or Clearstream
Banking, societe anonyme.

     Investors may hold their interests in the Regulation S Global Note directly
through Euroclear or Cedel, or through organizations other than Euroclear or
Cedel that are participants in the DTC system. Euroclear and Cedel will hold the
interests in the Regulation S Global Note on behalf of their participants
through customers' securities accounts in their respective names on the books of
their respective depositaries. These depositaries, in turn, will hold the
interests in the Regulation S Global Note in customers' securities accounts in
the depositaries' names on the books of DTC.

     Institutional Accredited Investor Global Note. In connection with the sale
of notes to an institutional accredited investor, beneficial interests in any of
the global notes may be exchanged for interests in a separate note in registered
form, without interest coupons (the "Institutional Accredited Investor Global
Note"), which was deposited on the original issue date of the outstanding notes
with, or on behalf of, a custodian for DTC in the manner described in the
preceding paragraphs.

     Except as set forth below, the rule 144A Global Note, the Regulation S
Global Note and the Institutional Accredited Investor Global Note (collectively,
the "global notes") may be transferred, in whole and not in part, solely to
another nominee of DTC or to a successor of DTC or its nominee. Beneficial
interests in the global notes may not be exchanged for notes in physical,
certificated form except in the limited circumstances described below.

     All interests in the global notes, including those held through Euroclear
or Clearstream, may be subject to the procedures and requirements of DTC. Those
interests held through Euroclear or Clearstream may also be subject to the
procedures and requirements of those systems.

EXCHANGES AMONG THE GLOBAL NOTES

     Exchanges of beneficial interests in one global note for interests in
another global note will be subject to the applicable rules and procedures of
DTC and its direct and indirect participants, including Clearstream and
Euroclear. Any beneficial interest in one of the global notes that is
transferred to a person who takes delivery in the form of an interest in another
global note will, upon transfer, cease to be an interest in that global note and
become an interest in the global note to which the beneficial interest is
transferred and, accordingly, will then be subject to all transfer restrictions,
if any, and other procedures applicable to beneficial interests in the global
note to which the beneficial interest is transferred for as long as it remains
an interest in that global note.

CERTAIN BOOK-ENTRY PROCEDURES FOR THE GLOBAL NOTES

     The descriptions of the operations and procedures of DTC, Euroclear and
Clearstream set forth below are provided solely as a matter of convenience.
These operations and procedures are solely within the control of the respective
settlement systems and are subject to change by them from time to time. Neither
we nor the initial purchasers takes any responsibility for these operations or
procedures, and investors are urged to contact the relevant system or its
participants directly to discuss these matters.

     DTC has advised us that it is (1) a limited purpose trust company organized
under the laws of the State of New York, (2) a "banking organization" within the
meaning of the New York Banking Law, (3) a member of the Federal Reserve System,
(4) a "clearing corporation" within the meaning of the Uniform Commercial Code,
as amended and (5) a "clearing agency" registered under Section 17A of the
Exchange Act. DTC was created to hold securities for its participants and
facilitates the clearance and settlement of securities transactions between
participants through electronic book-entry changes to the accounts of its
participants, which eliminates the need for physical transfer and delivery of
certificates. DTC's participants include securities brokers and dealers,
including the initial purchasers, banks and trust companies, clearing
corporations and certain other organizations. Indirect access to DTC's system is
also available to other entities such as banks, brokers, dealers and trust
companies, referred to as "indirect participants", that clear through or
maintain a custodial relationship with a participant, either directly or
indirectly. Investors who are not participants may beneficially own securities
held by or on behalf of DTC only through participants or indirect participants.

     Under procedures established by DTC (1) upon deposit of each global note,
DTC credited the accounts of participants designated by the initial purchasers
with an interest in the global note and (2) ownership of the notes is shown on,
and the transfer of ownership of the notes will be effected only through,
records maintained by DTC, with respect to the interests of participants, and
the records of participants and the indirect participants, with respect to the
interests of persons other than participants.

     The laws of some jurisdictions may require that some types purchasers of
securities take physical delivery of the securities in definitive form.
Accordingly, the ability to transfer interests in the notes represented by a
global note to these persons may be limited. In addition, because DTC can act
only on behalf of its participants, who in turn act on behalf of persons who
hold interests through participants, the ability of a person having an interest
in notes represented by a global note to pledge or transfer the interest to
persons or entities that do not participate in DTC's system, or to otherwise
take actions in respect of the interest, may be affected by the lack of a
physical definitive security in respect of the interest.

     So long as DTC or its nominee is the registered owner of a global note, DTC
or its nominee, as the case may be, will be considered the sole owner or holder
of the notes represented by the global note for all purposes under the
indenture. Except as provided below, owners of beneficial interests in a global
note will not be entitled to have notes represented by the global note
registered in their names, will not receive or be entitled to receive physical
delivery of certificated notes, and will not be considered the owners or holders
of notes under the indenture for any purpose, including with respect to the
giving of any direction, instruction or approval to the trustee under the
indenture. Accordingly, each holder owning a beneficial interest in a global
note must rely on the procedures of DTC and, if the holder is not a participant
or an indirect participant, on the procedures of the participant through which
the holder owns its interest, to exercise any rights of a holder of notes under
the indenture or a global note. We understand that under existing industry
practice, in the event that we request any action of holders of notes, or a
holder that is an owner of a beneficial interest in a global note desires to
take any action that DTC, as the holder of the global note, is entitled to take,
DTC would authorize the participants to take the action and the participants
would authorize holders owning through the participants to take the action or
would otherwise act upon the instruction of the holders. Neither we nor the
trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of notes by DTC, or for maintaining,
supervising or reviewing any records of DTC relating to the notes.

                                       126
<PAGE>   131

     Payments with respect to the principal of, and premium, if any, liquidated
damages, if any, and interest on, any notes represented by a global note
registered in the name of DTC or its nominee on the applicable record date will
be payable by the trustee to or at the direction of DTC or its nominee in its
capacity as the registered holder of the global note representing the notes
under the indenture. Under the terms of the indenture, the issuers and the
trustee may treat the persons in whose names the notes, including the global
notes, are registered as the owners of the notes for the purpose of receiving
payment on the notes and for any and all other purposes whatsoever. Accordingly,
neither we nor the trustee has or will have any responsibility or liability for
the payment of these amounts to owners of beneficial interests in a global note,
including principal, premium, if any, liquidated damages, if any, and interest.
Payments by the participants and the indirect participants to the owners of
beneficial interests in a global note will be governed by standing instructions
and customary industry practice and will be the responsibility of the
participants or the indirect participants and DTC.

     Transfers between participants in DTC will be effected in accordance with
DTC's procedures, and will be settled in same-day funds. Transfers between
participants in Euroclear or Clearstream will be effected in the ordinary way in
accordance with their respective rules and operating procedures.

     Subject to compliance with the transfer restrictions applicable to the
notes, cross-market transfers between the participants in DTC, on the one hand,
and Euroclear or Clearstream participants, on the other hand, will be effected
through DTC in accordance with DTC's rules on behalf of Euroclear or
Clearstream, as the case may be, by its respective depositary; however, these
cross-market transactions will require delivery of instructions to Euroclear or
Clearstream, as the case may be, by the counterparty in the system in accordance
with the rules and procedures and within the established deadlines (Brussels
time) of the system. Euroclear or Clearstream, as the case may be, will, if the
transaction meets its settlement requirements, deliver instructions to its
respective depositary to take action to effect final settlement on its behalf by
delivering or receiving interests in the relevant global notes in DTC, and
making or receiving payment in accordance with normal procedures for same-day
funds settlement applicable to DTC. Euroclear participants and Clearstream
participants may not deliver instructions directly to the depositaries for
Euroclear or Clearstream.

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

     Although DTC, Euroclear and Clearstream have agreed to the foregoing
procedures to facilitate transfers of interests in the global notes among
participants in DTC, Euroclear and Clearstream, they are under no obligation to
perform or to continue to perform these procedures, and these procedures may be
discontinued at any time. Neither we nor the trustee will have any
responsibility for the performance by DTC, Euroclear or Clearstream or their
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.

CERTIFICATED NOTES

     If (1) we notify the trustee in writing that DTC is no longer willing or
able to act as a depositary or DTC ceases to be registered as a clearing agency
under the Exchange Act and a successor depositary is not appointed within 90
days of this notice or cessation, (2) we, at our option, notify the trustee in
writing that they elect to cause the issuance of notes in definitive form under
the indenture or (3) upon the occurrence and continuation of an event of default
under the indenture if DTC so requests, then, upon surrender by DTC of the
global notes, certificated notes will be issued to each person that DTC
identifies as the beneficial owner of the notes represented by the global notes.
Upon any issuance, the trustee is

                                       127
<PAGE>   132

required to register the certificated notes in the name of the person or persons
or the nominee of any of these persons and cause the same to be delivered to
these persons.

     Neither we nor the trustee shall be liable for any delay by DTC or any
participant or indirect participant in identifying the beneficial owners of the
related notes and each of these persons may conclusively rely on, and shall be
protected in relying on, instructions from DTC for all purposes, including with
respect to the registration and delivery, and the respective principal amounts,
of the notes to be issued.

                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the material federal income tax consequences
of ownership of the notes. This discussion is a general summary only and does
not address all tax aspects of ownership of the notes that may be relevant to a
prospective investor's particular circumstances. This discussion deals only with
notes held as capital assets and does not deal with the consequences to special
classes of holders of the notes, such as dealers in securities or currencies,
life insurance companies, tax exempt entities, financial institutions, persons
with a functional currency other than the U.S. dollar, U.S. expatriates or
investors in pass-through entities such as partnerships. It does not deal with
the effects of any arrangement entered into by a holder of the notes that
partially or completely hedges the notes, or otherwise holds the notes as part
of a synthetic security or other integrated investment. In general, this
discussion assumes that a holder acquires notes at original issue. The
discussion is based upon the Internal Revenue Code of 1986, as amended, and the
related regulations, rulings, and judicial decisions as of the date of this
prospectus, any of which may be repealed or modified in a manner resulting in
federal income tax consequences that differ from those described below. This
discussion does not address the tax considerations arising under the laws of any
foreign, state or local jurisdiction. In addition, the discussion relies upon
the description provided to us by the DTC, Euroclear, and Clearstream of their
depository procedures and the procedures of their participants and indirect
participants in maintaining a book-entry system reflecting beneficial ownership
of the notes.

     PURCHASERS OF THE NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING
U.S. FEDERAL INCOME TAX CONSEQUENCES RESULTING FROM THEIR PARTICULAR SITUATIONS,
AND STATE, LOCAL, FRANCHISE, GIFT AND ESTATE TAX CONSEQUENCES, OR OTHER
CONSEQUENCES UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION.

U.S. HOLDERS

     The following discussion addresses the U.S. federal income tax consequences
to a U.S. holder of a note. For purposes of this discussion, a "U.S. holder" is
a noteholder that is (1) a citizen or resident of the United States for United
States federal income tax purposes, including an alien individual who is a
lawful permanent resident of the United States or meets the "substantial
presence" test prescribed under the Code, (2) a corporation, partnership, or
other entity organized under the laws of the United States or any political
subdivision of the United States, (3) an estate taxed by the United States
without regard to its source of income or (4) a trust if the trust has validly
elected to be treated as a United States person for U.S. federal income tax
purposes or if (a) a court within the United States can exercise primary
supervision over its administration and (b) one or more United States persons
have authority to control all of its substantial decisions.

  Exchange Offer in Connection with Registration of the Notes

     We have obtained an opinion from Kirkland & Ellis that the exchange of the
outstanding notes for the exchange notes, which have substantially identical
terms, in connection with the registration of the exchange notes will not be a
taxable event for federal income tax purposes. Consequently, no gain or loss
will be recognized by U.S. holders and non-U.S. holders of the outstanding notes
upon receipt of the exchange notes and ownership of the exchange notes will be
considered a continuation of ownership of the outstanding notes. For purposes of
determining gain or loss upon the subsequent sale or exchange of the exchange
notes, a holder will have the same tax basis and holding period in the exchange
notes that the holder had in the outstanding notes. The U.S. federal income tax
consequences of holding and disposing of the exchange notes will be the same as
those of holding and disposing of the outstanding notes.

  Payments of Interest

     Payments of stated interest on a note will be taxable as ordinary interest
income at the time it is received or accrued, depending upon the method of
accounting applicable to the holder of the note.

                                       129
<PAGE>   134

  Additional Interest

     The interest rate on the notes may be increased if the notes are not
registered with the SEC within prescribed time periods. We believe that the
possibility that any additional interest will be paid is "remote and incidental"
under applicable Treasury Regulations and, therefore, that any additional
interest will be taxable to U.S. holders at the time that it accrues or is
received in accordance with each U.S. holder's method of accounting. The
Internal Revenue Service may take a different position, which could affect the
time when the additional interest, if any, would be taxable to a U.S. holder.

  Sale, Exchange or Retirement of the Notes

     Upon the sale, exchange or retirement of the notes, a U.S. Holder will
recognize gain or loss equal to the difference between the amount realized upon
the sale, exchange or retirement, less a portion allocable to any accrued and
unpaid interest, which will be taxable as ordinary income, and the U.S. holder's
adjusted tax basis in the notes. A U.S. holder's adjusted tax basis in the notes
generally will be the U.S. holder's cost of the notes, less any principal
payments received by the holder.

     Gain or loss recognized by a U.S. holder on the sale, exchange or
retirement of the notes will be capital gain or loss. The gain or loss will be
long-term capital gain or loss if the notes have been held by the U.S. holder
for more than twelve months. In the case of a noncorporate U.S. holder,
long-term capital gain is subject to a maximum U.S. Federal tax rate of 20%. The
deductibility of capital losses by U.S. holders is subject to certain
limitations.

  Market Discount

     Any gain or loss on a disposition of a note would generally be a capital
gain or loss. However, a subsequent purchaser of a note who did not acquire the
note at its original issue, and who acquires the note at a price that is less
than the stated redemption price of the note at its maturity (i.e., the face
amount of the note if it is issued at par), may be required to treat the note as
a "market discount bond." Any recognized gain on a disposition of the note would
then be treated as ordinary income to the extent that it does not exceed the
"accrued market discount" on the note. In general, accrued market discount is
that amount that bears the same ratio to the excess of the stated redemption
price of the note over the purchaser's basis in the note immediately after its
acquisition, as the number of days the purchaser holds the note bears to the
number of days after the date the purchaser acquired the note up to and
including the date of its maturity. In addition, there are rules deferring the
deduction of all or part of the interest expense on indebtedness incurred or
continued to purchase or carry the bond and permitting a purchaser to elect to
include accrued market discount in income on a current basis.

  Backup Withholding and Information Reporting

     In general, a U.S. holder of a note will be subject to backup withholding
at the rate of 31% with respect to interest, principal and premium, if any, paid
on a note unless the holder (1) is an entity, including corporations, tax-exempt
organizations and certain qualified nominees, that is exempt from withholding
and, when required, demonstrates this fact or (2) provides us with its Taxpayer
Identification Number ("TIN"), which, for an individual, would be the holder's
Social Security Number, certifies that the TIN provided is correct and that the
holder has not been notified by the Internal Revenue Service that it is subject
to backup withholding due to underreporting of interest or dividends and
otherwise complies with applicable requirements of the backup withholding rules.
In addition, payments of interest, principal and premium to U.S. holders that
are not corporations, tax-exempt organizations or qualified nominees will
generally be subject to information reporting requirements.

     The amount of any backup withholding from a payment to a U.S. holder will
be allowed as a credit against the holder's federal income tax liability and may
entitle the holder to a refund, provided that the required information is
furnished to the Internal Revenue Service.

NON-U.S. HOLDERS

     The following discussion addresses the principal U.S. federal income tax
consequences to a noteholder that is not a U.S. holder. We refer to these
holders in this discussion as non-U.S. holders. As discussed above, this
discussion does not address all tax aspects of ownership of the notes that may
be relevant to a prospective investor's particular circumstances, including
holding the notes through a partnership or holding the notes through a hybrid
entity, i.e. an entity that is a pass-through entity for U.S. tax purposes but
not for foreign tax purposes.

  Payments of Interest

     Generally, payments of stated interest on a note will not be subject to
U.S. federal income tax if the interest qualifies as portfolio interest.
Interest on the notes will qualify as portfolio interest if the non-U.S. holder
(1) does not actually or constructively own 10% or more of the total combined
voting power of our voting stock, (2) is not a "controlled foreign corporation"
with respect to which we are a "related person," as those terms are defined in
the Internal Revenue Code and (3) provides the required certifications that the
beneficial owner of the notes is not a U.S. person. However, the interest on the
notes will be taxed at regular U.S. federal income tax rates if the interest
constitutes income that is effectively connected with the conduct of a U.S.
trade or business and, if the non-U.S. holder can claim the benefit of an income
tax treaty, the interest is attributable to a U.S. permanent establishment or
fixed base. This income is referred to in this discussion as U.S. trade or
business income. If the non-U.S. holder is a corporation, interest that
constitutes U.S. trade or business income may also be subject to the "branch
profits tax" at 30% or, if applicable, a lower rate determined by an income tax
treaty.

     Interest that neither qualifies as portfolio interest nor constitutes U.S.
trade or business income will be subject to U.S. withholding tax at the rate of
30%, unless the withholding tax is reduced or eliminated by an applicable income
tax treaty. To claim the protection of an income tax treaty, a non-U.S. holder
must provide a properly executed Form 1001 prior to the payment of interest, and
must periodically update Form 1001 or, if necessary, provide us with the
applicable successor form. New regulations scheduled to take effect on January
1, 2001, will replace these forms with new forms and procedures, and may require
a non-U.S. holder to obtain a TIN and provide documentary evidence of residence
in order to claim a treaty benefit.

  Sale, Exchange or Redemption of Notes

     Gain realized by a non-U.S. holder on the sale, exchange, redemption or
other disposition of a note generally will not be subject to U.S. federal income
tax unless (1) the gain constitutes U.S. trade or business income, (2) the
non-U.S. holder is an individual who holds the note as a capital asset and is
present in the United States for 183 days or more in the taxable year of the
disposition or (3) the non-U.S. holder is a former citizen or resident of the
United States subject to certain rules related to that status.

  Federal Estate Tax

     Notes held by an individual who is not a citizen or resident of the United
States for U.S. federal estate tax purposes at the time of his or her death will
not be subject to U.S. federal estate tax if the interest on the notes qualifies
for the portfolio interest exemption from U.S. federal income tax under the
rules described above.

  Information Reporting and Backup Withholding

     We must report to the Internal Revenue Service and to each non-U.S. holder
any interest that is subject to U.S. withholding tax or that is exempt from
withholding tax under either a tax treaty or the portfolio interest exemption.
Copies of these information returns may also be available to the tax

                                       131
<PAGE>   136

authorities of the country in which the non-U.S. holder resides under the
provisions of various treaties or agreements for the exchange of information.

     Non-U.S. holders other than corporations may be subject to backup
withholding and additional information reporting. Neither backup withholding nor
information reporting will apply to payments of portfolio interest by us to a
non-U.S. holder if the non-U.S. holder properly certifies that it is not a U.S.
holder or otherwise establishes an exemption. However, the certification or
exemption is not effective if we or our paying agent has actual knowledge that
the holder is a U.S. holder or that the conditions of another exemption relied
upon by the non-U.S. holder are not satisfied.

     Payments of principal on the notes by us to a non-U.S. holder may be
subject to backup withholding and information reporting unless the non-U.S.
holder properly certifies as to those items described below in connection with
payments made by brokers or otherwise establishes an exemption, provided that
neither we nor our paying agent has actual knowledge that the holder is a U.S.
holder or that the conditions of another exemption relied upon by the non-U.S.
holder are not satisfied.

     Neither backup withholding nor information reporting will apply to the
payment of proceeds from the disposition of the notes to or through the U.S.
office of any broker if the non-U.S. holder (1) properly certifies (A) that he
is not a U.S. holder, (B) that he does not expect to be present within the
United States for 183 days or more during the calendar year and (C) none of his
gains from transactions effected with the payor during the calendar year are
expected to be effectively connected with a U.S. trade or business; or (2)
otherwise establishes an exemption, and neither we nor our paying agent has
actual knowledge that the conditions of any claimed exemption are not satisfied.
If proceeds from the disposition of the notes are paid to or though the foreign
office of a U.S. broker, information reporting, but not backup withholding, is
required unless the broker has documentary evidence that the owner is a foreign
person and the broker has no actual knowledge to the contrary. Similar rules
apply to the foreign office of a foreign broker if either (1) the foreign broker
is a controlled foreign corporation with the meaning of the Internal Revenue
Code or (2) 50% or more of the gross income of the foreign broker during a
specified testing period was effectively connected with the conduct of a trade
or business within the United States. If proceeds from the disposition of the
notes are paid to or through the foreign office of a foreign broker that does
not have these characteristics, neither information reporting nor backup
withholding is required.

     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to a non-U.S. holder will be allowed as
a refund or credit against the non-U.S. holder's federal income tax liability.

     New regulations revising the information and reporting rules will become
effective on January 1, 2001. In general, these new regulations will not
materially change the withholding and information reporting requirements, but
will change various forms and certification procedures. Non-U.S. holders should
consult their own tax advisors concerning the applicability and effect, if any,
of the new regulations on an investment in the exchange notes.

                              PLAN OF DISTRIBUTION

     Each participating broker-dealer that receives exchange notes for its own
account as a result of the exchange offer must acknowledge that it will deliver
a prospectus in connection with any resale of the exchange notes. This
prospectus, as it may be amended or supplemented from time to time, may be used
by a participating broker-dealer in connection with resales of exchange notes
received in exchange for outstanding notes if the outstanding notes were
acquired as a result of market-making activities or other trading activities. We
have agreed that we will make this prospectus, as amended or supplemented,
available to any participating broker-dealer for use in connection with these
resales for a period of time as is necessary to comply with applicable law;
provided that this period shall not be required to exceed 270 days.

                                       132
<PAGE>   137

     We will not receive any proceeds from any sales of the exchange notes by
participating broker dealers. Exchange notes received by participating
broker-dealers for their own account as a result of 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 these methods of resale, at market prices
prevailing at the time of resale, at prices related to prevailing market prices
or negotiated prices. Any 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 a participating broker-dealer and/or the
purchasers of any exchange notes. Any participating broker-dealer that resells
the exchange notes that were received by it for its own account as a result of
the exchange offer and any broker or dealer that participates in a distribution
of the exchange notes may be deemed to be an "underwriter" within the meaning of
the Securities Act and any profit on the resale of the exchange notes and any
commissions or concessions received by these 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 participating broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.

     For a period of one year after the expiration date we will promptly send
additional copies of this prospectus and any amendment or supplement to this
prospectus to any participating broker-dealer that requests these documents in
the letter of transmittal.

     Prior to the exchange offer, there has not been any public market for the
outstanding notes. The outstanding notes have not been registered under the
Securities Act and will be subject to restrictions on transferability to the
extent that they are not exchanged for exchange notes by holders who are
entitled to participate in this exchange offer. The holders of outstanding
notes, other than any holder that is our affiliate within the meaning of Rule
405 under the Securities Act, who are not eligible to participate in the
exchange offer are entitled to certain registration rights, and we are required
to file a shelf registration statement with respect to their outstanding notes.
The exchange notes will constitute a new issue of securities with no established
trading market. We do not intend to list the exchange notes on any national
securities exchange or to seek the admission of the notes to trading in the
National Association of Securities Dealers Automated Quotation System. In
addition, any market making activity will be subject to the limits imposed by
the Securities Act and the Exchange Act and may be limited during the exchange
offer and the pendency of the shelf registration statements. 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 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, it
may be discontinued at any time.

                                 LEGAL MATTERS

     The validity of the exchange notes and the guarantees and other legal
matters, including the tax-free nature of the exchange, will be passed upon on
our behalf by Kirkland & Ellis, a partnership that includes professional
corporations, Chicago, Illinois.

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY LISN HOLDINGS, INC.)

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. BASIS OF PRESENTATION

OVERVIEW

     The interim consolidated financial statements of Orius Corp. ("Orius"), the
successor to LISN Holdings, Inc. ("LISN"), and its subsidiaries (the "Company")
as of June 30, 2000 and December 31, 1999 and for the period ended June 30, 2000
and 1999 include the accounts of Orius and its subsidiaries and in the opinion
of management, includes all necessary adjustments, consisting of only normal
recurring adjustments, to present fairly the consolidated financial position and
results of operations of the Company for the periods presented. The accompanying
unaudited consolidated financial statements have been prepared by the Company,
without audit. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted, although the Company believes that
the disclosures made are adequate to make the information presented not
misleading. Accordingly, these unaudited consolidated financial statements and
related notes should be read in conjunction with the consolidated financial
statements and notes thereto included in this prospectus. Reported interim
results of operations are based in part on estimates, and are not necessarily
indicative of those expected for the year.

     The financial information as of and for the period ended June 30, 1999
represents the information of LISN, which was deemed the accounting acquirer in
the December 15, 1999 business combination.

ORIUS/LISN TRANSACTION

     On December 15, 1999, Orius and LISN entered into a business combination in
which the former stockholders of LISN acquired control of Orius and its
subsidiaries. Accordingly, LISN is considered the acquiring corporation and
corporate predecessor for accounting purposes. Also in connection with the
transaction, the Company entered into a $275.0 loan and credit facility and a
$100.0 million bridge loan that were utilized to pay off all the outstanding
debt of the Company and LISN as of December 14, 1999 (the valuation date). The
bridge loan and a portion of the loan and credit facility have been retired with
the proceeds of a private placement of Senior Subordinated Debt in February
2000.

2. STOCK SPLIT

     On March 9, 2000, the Orius Board of Directors authorized a 10 for 1 stock
split. All share amounts presented in these financial statements have been
restated to reflect the split.

3. ORIUS/LISN TRANSACTION

     On December 15, 1999, LISN's former shareholders acquired control of Orius
and its wholly-owned subsidiary, NATG, through the following steps:

     - Former LISN shareholders, members of management and certain co-investors
       invested an aggregate cash amount of $112.2 million in LISN immediately
       prior to the transaction. In exchange for this investment, a "strip" of
       Orius securities were issued comprised of $41.3 million of junior
       subordinated notes, $60.8 million of Series C redeemable preferred stock
       and $10.1 million of common stock.

     - Former LISN shareholders exchanged LISN common stock, preferred stock and
       junior subordinated notes for a similar strip of securities issued by
       Orius.

     - NATG borrowed $328.5 million under the new multi-tranche senior credit
       facilities and the senior subordinated term loan, and repaid
       approximately $256.1 million of LISN and Orius indebtedness.

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY LISN HOLDINGS, INC.)

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)

     - Convertible preferred stock, junior subordinated notes, warrants and a
       portion of the common stock of Orius were redeemed. This redemption
       included put and call arrangements with certain Orius security holders
       which will require payment of approximately $54.9 million and the
       issuance of additional strips of Orius securities in the first half of
       2000.

     - Orius management rolled over approximately one-half of the value of their
       equity interests in Orius for a strip of securities comprised of $30.4
       million in aggregate principal amount of Orius junior subordinated notes,
       $44.7 in preferred stock and $8.3 million in common stock. Although LISN
       is the acquiring corporation for accounting purposes, the transaction
       resulted in LISN becoming a wholly-owned subsidiary of NATG which is a
       wholly-owned subsidiary of Orius.

     As the accounting predecessor, LISN's historical financial statements are
the historical financial statements of Orius.

     The total purchase consideration of $165.5 million in cash and $83.5
million in Orius rollover value (excluding amounts payable under put/call
arrangements) plus transaction related expenses of $6.3 million exceeded the
fair value of the tangible net assets acquired by $360.5 million, which is being
amortized on a straight-line basis over 25 years.

4. ACCOUNTS RECEIVABLE

     The allowance for doubtful accounts was $974,581 and $916,601 at June 30,
2000 and December 31, 1999, respectively. Included in accounts receivable at
June 30, 2000 are unbilled receivables of $13,545,667 and retainage of
$12,475,593.

     The balances billed but not paid by customers pursuant to retainage
provisions in customer contracts will be due upon completion of the contracts,
substantially all of the retention balances at March 31, 2000 are expected to be
collected within the next twelve months. Unbilled accounts receivable relate to
the Company's unit based contracts and represent revenue the Company is entitled
to based upon the units delivered as of the balance sheet date.

7. LONG-TERM DEBT AND CAPITAL LEASES

     In December 1999 NATG entered into a new credit agreement with Deutsche
Bank Securities Inc., Bankers Trust and a syndication of banks. The new credit
agreement includes a revolving credit facility, in an aggregate amount not to
exceed $100 million at any time, maturing on December 12, 2004, and a $275
million senior secured term loan credit facility. The term loan facility was
allocated among a $75 million Term Loan A with a letter of credit facility,
maturing on December 15, 2004; and a $200 million Term Loan B facility, maturing
December 15, 2006.

     During the first quarter of 2000, the company completed a private offering
of $150 million of 12.75% Senior Subordinated Notes due in 2010. A portion of
the proceeds from this offering was used to pay down the principal amount
outstanding on Term Loan B.

     Amounts under the revolving credit facility and Term Loan A facility bear
interest, at NATG's choice, of either the Federal Funds Rate plus 0.50% or the
Eurodollar rate, in each case plus an applicable margin of 0.75% to 2.00% and
1.75% to 3.00%, respectively, determined on the most recent total debt to

EBITDA ratio. Amounts under Term Loan B facility bear interest, at the Company's
choice, of either Bankers Trust Prime Rate or the Federal Funds Rate plus 0.50%,
in either case plus a margin of 2.50%. Loans made under the revolving credit
facility and the Term Loan A facility are collateralized by a pledge of all the
assets of the Company and its subsidiaries. The credit facility also contains
affirmative and negative covenants relating to the Company's operations. The
Company was in compliance with these covenants at June 30, 2000.

     As of June 30, 2000 and December 31, 1999, long-term debt and capital lease
obligations consisted of the following:

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY LISN HOLDINGS, INC.)

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)

     As discussed in the footnotes to the December 31, 1999 audited financial
statements certain of the Orius securities were subject to put and call
arrangements whereby Orius Corp. had a call and the security holders had a put.
In March 2000, the Series B preferred stock and $3,610,964 of the redeemable
common stock were redeemed by Orius Corp. In connection with those redemptions,
NATG borrowed $41.1 million from its credit facilities. The remainder of the
redeemable common stock was redeemed by the Company in the second quarter
through borrowings from its credit facilities and the issuance of junior
subordinated debt and preferred stock.

9. SERIES C PARTICIPATING PREFERRED STOCK

     The Orius Series C participating preferred stock accrues dividends daily at
a rate of 12% per annum based on a liquidation value $1,000 per share and
participates in any dividends paid to holders of the common stock. The Series C
participating preferred stock will be redeemed on December 31, 2019 at its
purchase price, plus accrued dividends and the liquidation value of the common
stock into which it is convertible.

     At June 30, 2000 and December 31, 1999, the total recorded value of the
Series C preferred stock has been determined based upon purchase price of $1,000
per share, accrued and unpaid dividends of $11,852,610 and $995,918,
respectively, and a value per common share of $7.77 and $1.34 (adjusted for the
stock split discussed in Note 2), respectively. The purchase price of $1,000 per
share and the value per common share of $1.34 were based upon the values of the
preferred and common stock purchased in connection with the Orius/LISN
transaction. Subsequent value per common share is adjusted quarterly based upon
the Company's performance, recent transactions and comparable trading multiples.

     For the period ended December 31, 1999, the amount attributable to the
accretion of the Series C preferred stock of $78,816,000, reflects the
adjustment to the preferred stock held by the former LISN shareholders. For the
six months ended June 30, 2000 the resulting accretion is $19,626,842. Accretion
is recorded as an increase in the retained deficit and a reduction of the income
available to common shareholders.

10. NOTE DUE FROM STOCKHOLDER

     In January 2000, pursuant to an employment agreement, the Company issued
188,810 shares of restricted common stock with a 5-year vesting period to its
chairman and chief executive officer. These shares were purchased at fair value
as determined by the LISN transaction in return for a full recourse promissory
note with a term of 5 years and a stated interest rate of 6.46%. At June 30,
2000, the balance due of $252,633 is shown as a reduction in stockholders'
equity.

11. SUBSEQUENT EVENTS

     In July 2000 the Company entered into additional borrowings of $60 million
under Term Loan C of the senior credit facility which were primarily used to pay
down amounts due under the revolving credit facility. Amounts under the Term
Loan C due September 30, 2007 facility bear interest, at the Company's option,
of either the higher of the Prime Rate or the overnight Federal Funds Rate plus
0.50% and a margin of 2.75%, or the Eurodollar rate and a margin of 3.75%.

To the Board of Directors
of Orius Corp.

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of income, stockholders' equity (net capital
deficiency) and of cash flows present fairly, in all material respects, the
financial position of Orius Corp. and Subsidiaries (formerly LISN Holdings,
Inc., the Company) as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999, in conformity with accounting principles generally accepted
in the United States. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with auditing standards generally accepted in the
United States, which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY LISN HOLDINGS, INC.)

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        DECEMBER 31, 1999, 1998 AND 1997

1. BASIS OF PRESENTATION

OVERVIEW

     Orius Corp. (Orius or the Company), a holding company with no independent
operations, is the parent of NATG Holdings, LLC (NATG) and is the successor to
LISN Holdings, Inc. (LISN, formerly Arion, Inc.). NATG is engaged in the
business of providing telecommunications infrastructure services in the
continental United States.

     Prior to the Orius/LISN transaction discussed below, LISN and Orius Corp.
and its subsidiaries operated separate businesses. During 1999, LISN underwent a
recapitalization, and later in 1999 LISN and Orius entered into a business
combination. See Note 15 for further discussion. The 1998 and 1997 financial
statements presented herein are those of LISN. The 1999 statement of income
presents the operation of only LISN through December 14, 1999 and includes the
operations of NATG from December 15, 1999 through December 31, 1999.

LISN RECAPITALIZATION

     On May 28, 1999, Arion, Inc. (Arion) entered into a Recapitalization
Agreement whereby, Arion was renamed LISN Holdings, Inc. The assets of Arion
were then transferred to Arion Sub, Inc., a wholly-owned subsidiary of Arion.
Also, on May 28, 1999, the shareholders of LISN, Inc. contributed all of their
shares to Arion. Arion was formed in 1997 to purchase and warehouse LISN's
inventory. The combination of LISN Holdings, Inc. and LISN, Inc. has been
accounted for in a manner similar to a pooling of interests, as Arion and LISN
were owned by the same shareholders in exactly the same ownership percentages
and share amounts, and both the ownership and assets of the combined entity were
identical before and after the two companies were combined. Accordingly, the
1998 Arion financial statements have been restated and referred to here as LISN
Holdings, Inc. LISN, Inc. continued to operate as a wholly-owned subsidiary of
Arion. In connection with this reorganization, Arion entered into a $75,000,000
credit facility that was utilized to pay off all outstanding debt of LISN, Inc.
as of May 27, 1999, and to finance the redemption of Arion's outstanding shares.
For further information, see Note 3.

ORIUS/LISN TRANSACTION

     On December 15, 1999, Orius and LISN entered into a business combination in
which the former stockholders of LISN acquired control of Orius and its
subsidiaries. Accordingly, LISN is considered the acquiring corporation and
corporate predecessor for accounting purposes. Also in connection with the
transaction, the Company entered into a $275,000,000 loan and credit facility
and a $100 million bridge loan that were utilized to pay off all the outstanding
debt of the Company and LISN as of December 14, 1999 (the valuation date). For
further information, see Note 5.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All material intercompany accounts and
transactions have been eliminated.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Significant estimates made in the preparation of these
financial

                                      F-17

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

statements include those related to the revenue recognized and costs and
expenses associated with contracts in process at period end, allowances for
doubtful accounts, and the estimated lives of long-lived assets. Actual results
could differ from those estimates and such differences may be material to the
financial statements.

REVENUE RECOGNITION

     Prior to the Orius/LISN transaction, substantially all of the Company's
revenues were earned from contracts under fixed price arrangements. For fixed
price contracts, the Company recognizes revenue and the related costs under the
percentage-of-completion method. Revenues and earnings from these contracts are
recognized as the related costs are incurred based on the relationship of costs
incurred to total estimated contract costs. Costs and estimated earnings in
excess of billings for contracts-in-progress represents revenue recognized but
not yet billed. Billings in excess of costs and estimated earnings represents
billings on contracts for which costs have not yet been incurred and revenue and
earnings have not been recognized.

     In connection with the Orius/LISN transaction, the Company assumed and
continues to offer contracts that provide for payments for units delivered by
the Company. These contracts generally entitle the Company to revenue for each
unit of work completed. Accordingly, the Company accounts for revenue and
related costs associated with these types of contracts using the
units-of-delivery revenue recognition method. Revenue is recognized as the
related units are completed, and costs allocable to the delivered units are
recognized as the cost of earned revenue. Unbilled revenues consist of
work-in-process on contracts based on management's estimate of work performed,
but not billed. All costs associated with unbilled revenues are recorded as
expenses in the same period as the unbilled revenue.

     Additionally, the Company recognizes revenues from short-term contracts
with duration less than two weeks under the completed contract method. Billings
and costs are accumulated on the balance sheet, and no profit is recorded before
completion or substantial completion of the work.

     At the time a loss on any contract becomes known, the entire amount of the
estimated loss is accrued.

CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments purchased with a
maturity of three months or less to be cash equivalents. For purposes of the
consolidated statements of cash flows, the Company considers these to be cash
equivalents.

PROPERTY AND EQUIPMENT

     Property and equipment are carried at cost less accumulated depreciation.
Depreciation is computed using the straight-line method over the estimated
useful lives of the assets ranging from 3 to 39 years. Leasehold improvements
are amortized over the remaining term of the facilities' lease. When assets are
retired or otherwise disposed of, the cost and related accumulated depreciation
are removed from the accounts and any resulting gain or loss is recognized in
the period. Expenditures for maintenance and repairs are expensed as incurred.

INVENTORY

     Inventories are stated at the lower of cost, on a first-in, first-out
basis, or market. Inventory consists of items purchased for use in projects and
substantially all of the Company's inventories can be used in multiple projects.

INCOME TAXES

     For federal tax purposes and in selected states, LISN had elected to be
treated under Subchapter S of the Internal Revenue Code. As such, all income,
expenses, and tax credits were passed through to the individual stockholders.
State taxes were paid by LISN and recorded in general and administrative
expenses in 1998 and 1997.

     Effective May 28, 1999, LISN converted to a C Corporation and accounts for
income taxes in accordance with Statement of Financial Accounting Standards No.
109 "Accounting for Income Taxes" ("SFAS 109"). SFAS 109 requires the use of the
liability method of computing deferred income taxes. Under this method deferred
income taxes are recorded to reflect the income tax consequences on future years
of temporary differences between the income tax and financial reporting bases of
assets and liabilities as of the balance sheet date. Under the liability method,
deferred income taxes are adjusted for tax rate changes as they occur. A net
deferred tax liability of $4,577,600 was established on May 28, 1999 as a result
of the conversion to a C corporation.

     The Company and its subsidiaries file a consolidated federal income tax
return. Deferred income taxes are provided for the temporary differences between
the financial reporting basis and the tax basis of the Company's assets and
liabilities.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair value of the Company's financial instruments approximate the
recorded values due to the relatively short terms of the instruments and the
floating interest rate on a substantial portion of the Company's debt. The
Company has entered interest rate cap arrangements, but the fair values of those
caps approximate their recorded values.

INTANGIBLE ASSETS

     The excess of the purchase price over the fair market value of the tangible
net assets of acquired businesses (goodwill) is amortized on a straight-line
basis over its estimated useful life of 25 years. The appropriateness of the
carrying value of goodwill is reviewed periodically by the Company at a
subsidiary level. An impairment loss for the difference between fair value and
recorded value is recognized when the projected undiscounted future cash flows
are less than the carrying value of goodwill. No impairment loss has been
recognized in the period presented. Amortization expense from the date of the
Orius/LISN transaction and included in these financial statements was $602,498
for 1999. The intangible assets at December 31, 1999 are net of accumulated
amortization of $602,498.

     Included in other assets are intangible assets for deferred financing costs
which are amortized over the term of the related debt facility. At December 31,
1999 deferred financing costs of $9,876,058 are included in other assets. For
1999, $755,267 of amortization expense related to these costs has been included
in interest expense.

CONCENTRATIONS OF CREDIT RISK

     Substantially all of the Company's accounts receivable are due from
companies within the telecommunications industry located throughout the United
States. Credit is extended based on an evaluation of the customer's financial
condition and, generally, collateral is not required. Credit losses are provided
for in the consolidated financial statements.

     The Company maintains various bank accounts and at times, amounts may be in
excess of FDIC insurance limits.

STOCK OPTION PLANS

     In October 1995, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock Based Compensation," which was effective for the Company beginning August
1, 1996. SFAS No. 123 requires expanded disclosures of stock based compensation
arrangements with employees, and encourages, but does not require, compensation
cost to be measured based on the fair value of the equity instrument awarded.
Under SFAS No. 123, companies are permitted, however, to continue to apply
Accounting Principle Board (APB) Opinion No. 25, which recognized compensation
based on the intrinsic value of the equity instrument awarded. The Company
applies APB Opinion No. 25 to its stock based compensation awards to employees.
See Note 19.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which establishes standards for the
accounting and reporting of derivative instruments, including certain derivative
instruments imbedded in other contracts (collectively referred to as
derivatives), and for hedging activities. It requires that an entity recognize
all derivatives as other assets or liabilities in the statement of financial
position, and measure those instruments at fair value. This statement is
effective for the Company's 2001 financial statements. Due to the complexity of
this statement, the Company is still evaluating its impact, if any, on our
financial statements.


     In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition" (SAB 101), which affects the recognition and disclosures
about revenues. SAB 101 is applicable for the Company's fourth quarter 2000
financial statements. Management expects its adoption will not be significant to
the financial statements.


3. RECAPITALIZATION

     On May 28, 1999, the Company sold 50.554778 shares of common stock for
$70,250,000 (less $2,518,849 of transaction related fees) and redeemed 95.149888
shares for $133,910,625 (less $6,500,000 which remained in the Company to fund
employee bonuses which were recorded as expenses). An additional $11,454,413
will be redeemed during 2000 and is reflected as a liability at December 31,
1999. Also on May 28, 1999, 41.81114 shares of common stock were converted to
Junior Notes (see Note 12) payable in the amount of $58,100,000 and 8.9894
shares of common stock were exchanged for 8.989394 shares of Series A Preferred
stock with a market value of $12,491,500. In accordance with the
Recapitalization Agreement, an additional 5.67469 shares of common stock were to
be redeemed for $7,885,450 on January 2, 2000.

4. STOCK SPLIT

     The LISN Board of Directors authorized a stock split (10,000 to 1)
effective August 16, 1999 resulting in 146,042.82 shares of common stock
outstanding and 89,894 shares of Preferred Series A stock outstanding. All share
amounts presented in these financial statements have been restated to reflect
the share split.

5. ORIUS/LISN TRANSACTION

     On December 15, 1999, LISN's former shareholders acquired control of Orius
and its wholly-owned subsidiary, NATG, through the following steps:

     - Former LISN shareholders, members of management and certain co-investors
       invested an aggregate cash amount of $112.2 million in LISN immediately
       prior to the transaction. In exchange for this
                                      F-20
<PAGE>   160
          ORIUS CORP. AND SUBSIDIARIES (FORMERLY LISN HOLDINGS, INC.)

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

       investment, a "strip" of Orius securities were issued comprised of $41.3
       million of junior subordinated notes, $60.8 million of Series C
       redeemable preferred stock and $10.1 million of common stock.

     - Former LISN shareholders exchanged LISN common stock, preferred stock and
       junior subordinated notes for a similar strip of securities issued by
       Orius.

     - NATG borrowed $328.5 million under the new multi-tranche senior credit
       facilities and the senior subordinated term loan, and repaid
       approximately $256.1 million of LISN and Orius indebtedness.

     - Convertible preferred stock, junior subordinated notes, warrants and a
       portion of the common stock of Orius were redeemed. This redemption
       included put and call arrangements with certain Orius security holders
       which will require payment of approximately $54.9 million and the
       issuance of additional strips of Orius securities in the first half of
       2000. See Notes 15 and 21.

     - Orius management rolled over approximately one-half of the value of their
       equity interests in Orius for a strip of securities comprised of $30.4
       million in aggregate principal amount of Orius junior subordinated notes,
       $44.7 in preferred stock and $8.3 million in common stock.

     Although LISN is the acquiring corporation for accounting purposes (because
former LISN shareholders acquired approximately 75% of common equity interests)
the transaction resulted in LISN becoming a wholly-owned subsidiary of NATG,
which is a wholly-owned subsidiary of Orius. As the accounting predecessor,
LISN's historical financial statements are the historical financial statements
of Orius and include the results of Orius' operations from December 15, 1999
through December 31, 1999.


     Of the total purchase price of $314.5 million, $163.7 million was paid in
cash to Orius stockholders in connection with the redemption for their existing
equity interests, $83.5 million represents the value of the Orius securities
which were retained by Orius stockholders or exchanged for new Orius equity, $61
million represents the amount of cash paid to Orius stockholders to redeem their
equity securities pursuant to the put/call arrangements (of which $54.9 million
remains outstanding at December 31, 1999) and $6.3 million represents
transaction related expenses. The purchase price of $314.5 million exceeded the
fair value of the tangible net assets acquired by $360.5 million, which is being
amortized on a straight-line basis over 25 years.


     The excess purchase price over the fair value of the assets acquired has
been allocated to goodwill. While the various synergies of the Orius/LISN
combination are readily identifiable, the company believes that these are not
reliably measurable and, accordingly, considers these to be elements of
goodwill.

6. PRO FORMA FINANCIAL INFORMATION (UNAUDITED)

     In addition to the recapitalization discussed in Note 3 and the Orius/LISN
transaction discussed in Note 5, Orius acquired twelve companies at various
times during 1998 and 1999 prior to the Orius/LISN transaction. The following
unaudited pro forma financial information represents the unaudited results of
operations as if the Orius/LISN transaction and the twelve Orius acquisitions
had occurred on January 1 of each year (in thousands):

7. ACCOUNTS RECEIVABLE

     The allowance for doubtful accounts was $916,601 and $252,000 at December
31, 1999 and 1998, respectively. Included in accounts receivable at December 31,
1999 are unbilled receivables of $13,532,519 and retainage of $8,188,908.

     The balances billed but not paid by customers pursuant to retaining
provisions in customer contracts will be due upon completion of the contracts
and acceptance by the customer. Based on the Company's experience with similar
contracts, the majority of the retention balances at December 31, 1999 are
expected to be collected within the next twelve months. Unbilled accounts
receivable relate to the Company's unit based contracts and represent revenue
the Company is entitled to based upon the units delivered as of the balance
sheet date.

8. COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS

     Contracts totaling $174.5 million and $57.4 million were in process at
December 31, 1999 and December 31, 1998, respectively. Costs and estimated
earnings, and related billings on uncompleted projects at December 31 are as

</TABLE>

     Included in accrued liabilities are post acquisition adjustments related to
companies acquired by NATG prior to the Orius/LISN transaction. Pursuant to
certain of the purchase agreements, the Company will be required to give
additional consideration of cash and Orius common stock to the former acquired
company shareholders upon attainment of specified financial criteria over the
period ended December 31, 1999 and the year ended December 31, 2000. The amount
of cash and shares to be issued cannot be determined until the periods expire
and the attainment of the criteria is established. The Company accounts for this
additional consideration when the specified financial criteria are achieved and
it is probable it will be paid. At December 31, 1999, based upon the attainment
of fiscal 1999 targets for certain acquisitions, additional consideration of
$3.0 million has been recorded as additional purchase price and included as a
liability to the former stockholders of the acquired companies. If targets are
achieved in 2000, the Company may be obligated to pay additional consideration
of $2.9 million and issue up to 120,000 shares of common stock. Additionally, at
December 31, 1999, certain purchase price adjustments in the amount of
approximately $5.6 million related to 1999 acquisitions have also been recorded.

11. INVESTMENTS

     During 1999, LISN purchased 49% interests in two telecommunications
infrastructure companies for aggregate consideration of $100,000. LISN also
entered into credit agreements totaling $1.15 million with these investees
pursuant to which LISN is committed to loaning funds for the investees' working
capital. The Company accounts for these investments under the equity method.

     Losses of $468,000 were recorded as part of other expense for 1999 which
represented the Company's 49% interest in the losses of the investees and
charges associated with anticipated losses on loans made under the credit

12. LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS

     As of December 31, 1998, the Company had a line of credit which allowed it
to borrow up to $10.0 million. The line of credit expired in May 1999. There
were no borrowings on this line of credit as of December 31, 1998.

     On May 28, 1999, in connection with the Recapitalization Agreement (see
Note 3), LISN entered into a new $100.0 million Credit Agreement with
BankBoston. N.A. ("BankBoston"). The balance due of $75.0 million plus accrued
interest of $1,689,522 was repaid in connection with the Orius/LISN transaction.
Unamortized deferred financing fees of $2,269,239 were written off resulting in
an extraordinary charge to income of $1,372,239, net of tax benefits of
$897,000.

     The Company moved into a new building in Amherst, Ohio in January 1998. The
Company entered into a 15 year mortgage note for $1.2 million with an annual
fixed interest rate of 9%, and monthly principal payments of $6,911 plus
interest through March 16, 2013. The balance due on this debt was $1.2 million
as of December 31, 1998. The outstanding balance was repaid in connection with
the Orius/ LISN transaction.

     On December 15, 1999, NATG entered into a new credit agreement with
Deutsche Bank Securities Inc., Bankers Trust and a syndication of banks. The new
credit agreement includes a revolving credit facility, in an aggregate amount
not to exceed $100 million at any time, maturing on December 15, 2004, and a
$275 million senior secured term loan credit facility. The term loan facility is
allocated among a $75 million Term loan A with a letter of credit facility,
maturing on December 15, 2004; and a $200 million Term loan B facility, maturing
on December 15, 2006. At December 31, 1999, the total letters of credit issued
under the $100 million revolving credit facility and the $75 million Term A loan
facility were approximately $9.3 million and $46.5 million, respectively.

     Amounts under the revolving credit facility and Term loan A facility bear
interest, at NATG's choice, of either the Federal Funds Rate plus 0.50% or the
Eurodollar rate, in each case plus an applicable margin of 0.75% to 2.00% and
1.75% to 3.00%, respectively, determined on the most recent total debt to EBITDA
ratio. Amounts under Term loan B facility bear interest, at NATG's choice, of
either Bankers Trust Prime Rate or the Federal Funds Rate plus 0.50%, in either
case plus a margin of 2.50%. Loans made under the revolving credit facility and
the Term loan A facility are collateralized by a pledge of all of the assets of
the Company and its subsidiaries. The credit facility also contains affirmative
and negative covenants relating to NATG's operations.

     On December 15, 1999, NATG also entered into a credit agreement with
various lending institutions for a $100 million senior subordinated bridge loan
(the Bridge Loan) maturing December 15, 2007. Amounts under the Bridge Loan bear
interest at the lower of LIBOR plus 6.5% or 16% per annum.

     At December 31, 1999, long-term debt and capital lease obligations
consisted of the following:

     In order to manage its interest rate risk, the Company entered into
interest rate cap agreements with aggregate notional amounts of $68.9 million at
December 31, 1999. These agreements limit the Company's exposure to increases in
LIBOR over 8%. The premiums paid for the interest rate caps were deferred and
are being amortized over the life of the caps and recognized as interest
expense.

12. JUNIOR SUBORDINATED NOTES

     On May 28, 1999, in connection with the Recapitalization Agreement, LISN
junior subordinated notes were issued for an aggregate principal balance of
$58.1 million in exchange for common stock. These notes bear interest at a rate
of 12% per annum compounded quarterly. On August 31, 1999, LISN issued an
additional $637,000 in junior notes in association with a private placement (see
Note 14).

     In connection with the Orius/LISN transaction, these notes were exchanged
for $62.6 million of Orius junior subordinated notes representing the aggregate
unpaid principal and accrued interest outstanding at December 15, 1999.

     In addition to the $62.6 million of junior subordinated notes exchanged
with the former LISN note holders, Orius junior subordinated notes were issued
to Orius management in the amount of $30.4 million in partial exchange for the
rollover of their equity value, and to new and existing investors in the amount
of $41.3 million in partial exchange for their cash investment.

     The Orius junior subordinated notes bear interest at a rate of 12% per
annum. A maximum of 40% of the interest is payable in cash beginning January 15,
2001 and the remainder is deferred and accrues as additional principal. Cash
interest may be paid by Orius only to the extent Orius has available funds. NATG
is limited by the terms of its debt agreements as to the amount of dividends
which may be paid to Orius. In the event of default by Orius, the holders of the
junior notes are prohibited from seeking remedy against NATG until all senior
debt obligations are repaid.

13. LISN SERIES A PREFERRED STOCK

     On May 28, 1999 the Company authorized 200,000 shares of Series A Preferred
Stock, par value $.01 per share. These shares bear interest at 12% per annum
paid in kind (no dividends to be received until liquidity event). These shares
rank senior to the common stock as to dividends and distributions upon the
Company's liquidation, winding up and dissolution. These shares are subordinated
to all of the Company's current and future liabilities and shall be redeemed on
December 31, 2019.

     In connection with the Orius/LISN transaction, these shares were converted
into shares of Orius Series C preferred stock and at December 31, 1999 no shares
of the Series A preferred stock remain outstanding.

14. PRIVATE PLACEMENTS OF LISN STRIPS

     During 1999, LISN sold to its employees strips of its securities for
$10,000 each. Each strip consisted of 10.7586 shares of LISN's Company's Class B
common stock, 10.8306 shares of LISN's Series A preferred stock, and $7,000
principal 12% Junior Subordinated Notes. LISN raised $910,000 through these
sales resulting in the issuance of 979.03 shares of common stock and 985.58
shares of Series A preferred stock for $136,045 and $136,955, respectively.

15. SECURITIES SUBJECT TO PUT AND CALL ARRANGEMENTS

     At December 31, 1999, securities subject to put and call arrangements are
as follows:

</TABLE>

     As discussed in Notes 1 and 5, certain of the Orius securities are subject
to put and call arrangements whereby Orius Corp. has a call and the security
holders have a put. In March 2000, the Series B preferred stock and a portion of
the redeemable common stock were redeemed by Orius Corp. In connection with
those redemptions, NATG borrowed $41.1 million from its credit facilities and
paid Orius Corp. the funds. It is expected that the remainder of the redeemable
common stock will be retired by the Company in the first half of 2000 and NATG
will be required to fund that redemption through borrowings from its credit
facilities.

16. SERIES C REDEEMABLE PARTICIPATING PREFERRED STOCK

     The Orius Series C participating preferred stock accrues dividends daily at
a rate of 12% per annum based on a liquidation value of $1,000 per share and
participates in any dividends paid to holders of the common stock. Upon a
liquidation of the Company, the holders of the Series C preferred stock would be
entitled to receive the liquidation value of their stock plus accrued and unpaid
dividends prior to any distributions to the holders of common stock. The Series
C preferred stock will be redeemed on December 31, 2019 at its purchase price,
plus accrued dividends and the liquidation value of the common stock into which
it is convertible.

     Upon an initial public offering, the Series C preferred stock is
convertible at the option of the holders of a majority of the Series C preferred
stock into shares of Series D preferred stock and common stock. Each share of
Series C preferred stock is convertible into (1) a number of shares of Series D
preferred with a liquidation value equal to $1,000 plus accrued and unpaid
dividends on the Series C preferred stock, plus (2) a number of shares of common
stock equal to $1,000 divided by the conversion price of the Series C preferred
stock.

     The Series D preferred stock is similar in rights and preferences to the
Series C preferred stock but is not convertible into common stock and is
redeemable by the company at any time. In addition, the holders of majority of
the Series D preferred stock can cause the company to redeem some or all of
their shares of Series D preferred stock at any time.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     At December 31, 1999, the total recorded value of the Series C preferred
stock has been determined based upon a purchase price of $1,000 per share,
accrued and unpaid dividends of $995,918 and a value per common share of $1.34.
The purchase price of $1,000 per share and the value per common share of $1.34
were based upon the values of the preferred and common stock purchased in
connection with the Orius/LISN transaction. Subsequent value per common share
and accretion will be adjusted quarterly based on the Company's performance,
recent transactions and comparable trading multiples.

     The amount attributable to the accretion to the redemption value of the
Series C preferred stock of $78,816,000 is recorded as a direct reduction of
retained earnings and is a reduction of income available to common shareholders
and reflects the adjustment to the fair value of the preferred stock held by the
former LISN shareholders.

18. PROFIT SHARING AND 401(k) PLANS

     The Company has a profit sharing plan covering all eligible employees, as
defined in the plan, which provides, in part, for annual discretionary Company
contributions not to exceed the maximum amount allowable as a deduction for
income tax purposes. Company contributions, included in general and

administrative expenses, were $1,050,000, $500,000 and $200,000 for the years
ended December 31, 1999, 1998 and 1997, respectively.

     The Company has a 401(k) plan for all eligible employees. Effective with
the payroll dates after January 1, 1998, the Company contribution rate was 75%
of the first 5% of compensation contributed by the employee. Total Company
contributions amounted to $317,294, $221,501 and $61,685 for the years ended
December 31, 1999, 1998 and 1997, respectively.

19. STOCK OPTION PLAN

     On July 19, 1999, the shareholders of the Company approved the Management
Equity Agreement Plan (the "Plan"). The Plan authorized the granting of stock
options for an aggregate of 3,398 shares of common stock to certain officers and
key employees of the Company at an option price of $138.96 which is the
estimated fair value on the effective date of the grant. The Options may be
exercised only to the extent they have vested. As long as an employee investor
remains employed by the Company or its Subsidiaries, 10% of such employee
investor's options will become vested annually on March 31 of each year for a
five year period commencing March 31, 2000 (each a "Vesting Date"). An
additional 10% of an employee investor's options may vest and become exercisable
on each Vesting Date, subject to achievement by the Company of target operating
performance levels for the Company's then most recently completed fiscal year,
which performance targets shall be determined annually in advance by the Board.
All remaining options shall vest and become exercisable on July 19, 2006 as long
as such employee investor has been and remains continuously employed by the
Company as of such date. Upon sale of the Company, all or any portion of the
options which have not previously vested shall become vested and exercisable
upon the occurrence of such event. The options shall expire on July 19, 2009, if
not earlier exercised. No options had vested as of December 31, 1999.

     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" for measuring compensation
expense. The Company has adopted the disclosure only provisions of Statement of
Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting for Stock-Based
Compensation". If the Company had adopted the measurement criteria for
calculating compensation expense prescribed by SFAS 123, there would have been
no effect on the Company's consolidated financial statements for the nine months
ended December 31, 1999.

     In connection with the LISN/Orius transaction, these options were equitably
adjusted and converted into options of Orius common stock.

20. SEGMENTS

     Prior to the Orius/LISN transaction on December 15, 1999, the Company
operated as one segment in the internal telecom service market providing
engineering, furnishing and installation of network equipment and related
components and maintenance services. Subsequent to the transaction and to
strategically manage its business, the Company has designated an additional
operating segment. The external telecom services segment provides installation,
design engineering and maintenance of fiber optic, coaxial and copper cable
networks for the telecom industry.

CREDIT LINES ISSUED TO INVESTEES

     As discussed in Note 10, the Company has made loan commitments to two
investees. Any loans made pursuant to these commitments are exclusively for
working capital purposes. At December 31, 1999, open commitments under these
loan agreements total $890,000.

LITIGATION

     The Company is involved in litigation from time to time in the ordinary
course of its business. In the opinion of management, it is expected that the
ultimate resolution of these matters will not have a material effect on the
Company's consolidated financial position or results of operations and cash
flows.

22. RELATED PARTY TRANSACTIONS

     Certain subsidiaries of NATG lease administrative offices from partnerships
and corporations of which certain officers of the subsidiaries are the general
partners or shareholders. The total expense under these arrangements for the
period December 15, 1999 to December 31, 1999, was insignificant. Future minimum

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

lease commitments under these arrangements are $140,715 in 2000, $121,500 in
2001, $83,070 in 2002 and $33,768 in 2003.

23. SUBSEQUENT EVENTS

     On January 31, 2000, the Company purchased Irwin Utilities of Texas, Inc.
for $16.8 million.

     On February 9, 2000, NATG and Orius Capital Corp. (the "Issuers"), a wholly
owned subsidiary of NATG, issued $150 million of 12 3/4% Senior Subordinated
Notes due 2010 (the Notes). The proceeds from the Notes were used to repay the
Bridge Loan and a portion of the Senior Term B. The Notes are fully and
unconditionally guaranteed by the Company and all operating subsidiaries.
Because (i) the direct and indirect subsidiaries are wholly owned by the
Company, (ii) there are no nonguarantor direct or indirect subsidiaries, (iii)
the guarantees and all direct and indirect subsidiaries are full and
unconditional, and joint and several and (iv) management has determined that the
financial statements of the guarantors would not be material to investors,
financial information of the Issuers and the guarantor subsidiaries has not been
disclosed in these financial statements. Additionally, there are no significant
restrictions on the Issuers' ability to obtain funds from the subsidiaries by
dividend or loan.

     During March 2000, Orius exercised its option to purchase $39.4 million of
its outstanding preferred stock and $1.7 million of its common stock. The funds
for the exercise of the call options were obtained from the Company's credit
facilities and the payment to Orius was reflected as a decrease in the Orius
Corp. securities subject to put and call arrangements.

     On March 9, 2000, the Orius Board of Directors authorized a 10 for 1 stock
split. All share amounts presented in these financial statements have been
restated to reflect the split.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Directors
of Orius Corp.

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of income, stockholders' equity (deficit) and
cash flows present fairly, in all material respects, the financial position of
Orius Corp. and its subsidiaries (formerly NATG Holdings, Inc.) at December 14,
1999 and December 31, 1998, and the results of their operations and their cash
flows for the year ended December 31, 1998 and the period ended December 14,
1999, in conformity with accounting principles generally accepted in the United
States. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with auditing standards generally accepted in the United States,
which 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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY NATG HOLDINGS, INC.)

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

                DECEMBER 14, 1999 AND DECEMBER 31, 1998 AND 1997

1. COMMENCEMENT AND NATURE OF OPERATIONS

     North American Tel-Com Group, Inc. (NATG) was formed in 1997 to create a
nationwide provider of comprehensive telecom infrastructure services. Prior to
March 31, 1998, NATG had no substantive operations. As further discussed in Note
2, NATG entered into a series of transactions with four other companies on March
31, 1998 and NATG began its commercial operations (the Simultaneous Business
Combination). Also discussed in Note 2, NATG went through a reorganization
during 1999 that resulted in the formation of Orius Corp. and NATG became an
indirect wholly-owned subsidiary of Orius Corp. (the Reorganization).

     Orius Corp. entered into a business combination with LISN Holdings, Inc. on
December 15, 1999. That transaction was accounted for as a reverse acquisition
purchase with LISN Holdings, Inc. being deemed the accounting acquiror. As a
result of the acquisition by LISN Holdings, Inc., the 1999 financial statements
present the operations for Orius Corp. and its subsidiaries (the Company) as of
and for the period ended December 14, 1999.

2. THE SIMULTANEOUS BUSINESS COMBINATION AND THE REORGANIZATION

THE SIMULTANEOUS BUSINESS COMBINATION

     On March 31, 1998, NATG and several other parties simultaneously entered
into a series of transactions and agreements including: a new stockholders'
agreement; preferred stock coupled with a redemption agreement (Notes 9 and 10)
and a junior subordinated note (Note 8) was issued to HIG Cable, Inc. (HIG), a
subsidiary of HIG Capital Management; a credit facility and loan agreement were
entered; and four stock exchange agreements were entered. The result of these
transactions was the commencement of Orius' operations.

     Pursuant to the new stockholders agreement and the four stock exchange
agreements, Channel Communications, Inc. (Channel); Cablemasters Corp.
(Cablemasters); Excel Cable Construction, Inc. (Excel); and Mich-Com Cable
Services Incorporated (Mich-Com) each exchanged its common stock for common
stock of NATG and cash. In accordance with APB Opinion No. 16, Channel was
deemed to be the accounting acquiror of the other companies involved in the
Simultaneous Business Combination. This designation was made because after
giving effect to the transactions on March 31, 1998, Channel held the largest
percentage of voting common stock and was the largest entity involved in the
Simultaneous Business Combination. Accordingly, the cash paid of $12.1 million
to the former Channel shareholders was accounted for as a reduction of Channel's
March 31, 1998 equity and no value was ascribed to the NATG shares of common
stock received by the former Channel shareholders.

     The 1997 financial statements presented herein are those of Channel.

THE REORGANIZATION

     At December 31, 1998, the organization consisted of eight subsidiaries
operating under NATG: Channel; Cablemasters; Excel; Mich-Com; U.S. Cable, Inc.
(U.S. Cable); CATV Subscriber Services, Inc. (CATV); Statewide CATV, Inc.
(Statewide); and Burn-Techs, Inc. (Burn-Techs). At December 31, 1998, the common
stock of NATG was owned by the former owners of these companies and certain
executive officers and founders of NATG. HIG Cable, Inc. owned all the
outstanding preferred stock.

     On February 8, 1999, a reorganization occurred in connection with the
acquisition of four companies and related financing. Orius Corp., a Delaware
corporation, was formed, and it formed NATG Holdings, LLC (NATG Holdings), a
Delaware limited liability company. Orius Corp. held all of the interest in NATG
Holdings. NATG Holdings formed a subsidiary, NATG Merger Sub., which was merged
with and

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY NATG HOLDINGS, INC.)

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

into NATG with NATG as the surviving corporation. As a result of the
Reorganization, NATG became an indirect wholly owned subsidiary of Orius. The
Reorganization resulted in all of the stockholders of NATG holding shares of
Orius.

     Shares of common and preferred stock of NATG were converted into one-tenth
of a share of common and preferred stock of Orius, respectively. This
one-for-ten exchange was the same for all stockholders and has been reflected in
these financial statements by restating all share amounts.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BUSINESS

     The Company's operations consist primarily of installation, design,
engineering, and maintenance services for the telecom industry in the United
States.

PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include Orius Corp. and its
subsidiaries, all of which are wholly-owned. All material intercompany accounts
and transactions have been eliminated.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Significant estimates made in the preparation of these
financial statements include those related to the revenue recognized and costs
and expenses associated with contracts in process at period end, allowances for
doubtful accounts, and the estimated lives of long-lived assets. Actual results
could differ from those estimates and such differences may be material to the
financial statements.

REVENUES

     Prior to the acquisitions made in 1999, substantially all of the Company's
revenues were earned from contracts that provided for payments for units
delivered by the Company. These contracts generally entitle the Company to
revenue for each unit completed. Accordingly, the Company accounts for revenue
and related costs associated with these types of contracts using the
units-of-delivery revenue recognition method. Revenue is recognized as the
related units are completed, and costs allocable to the delivered units are
recognized as the cost of earned revenue. Unbilled revenues consist of
work-in-process on contracts based on management's estimate of work performed,
but not billed. All costs associated with unbilled revenues are recorded as
expenses in the same period as the unbilled revenue. The Company also receives
advances from customers related to certain of these contracts which are
reflected as deferred revenues on the balance sheet.

     With the acquisitions discussed in Note 4, the Company assumed and began to
offer contracts under fixed price arrangements. Consequently, the Company
modified its revenue recognition policy to include these types of contracts. For
fixed price contracts, the Company recognizes revenue and the related costs
under the percentage-of-completion method. Revenues and earnings from these
contracts are recognized as the related costs are incurred based on the
relationship of costs incurred to total estimated contract costs. Costs and
estimated earnings in excess of billings for contracts-in-progress represents
revenue recognized but not yet billed. Billings in excess of costs and estimated
earnings represents billings on contracts for which costs have not yet been
incurred and revenue and earnings have not been recognized.

                                      F-38
<PAGE>   178
          ORIUS CORP. AND SUBSIDIARIES (FORMERLY NATG HOLDINGS, INC.)

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Additionally, NATG recognizes revenues from short-term contracts with
duration less than two weeks under the completed contract method. Billings and
costs are accumulated on the balance sheet, and no profit is recorded before
completion or substantial completion of the work.

     At the time a loss on any contract becomes known, the entire amount of the
estimated loss is accrued.

CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include all highly liquid investments with a
maturity of three months or less at the time of purchase. For purposes of the
consolidated statements of cash flows, the Company considers these to be cash
equivalents.

PROPERTY AND EQUIPMENT

     Property and equipment is stated at cost. Depreciation and amortization is
computed over the estimated useful life of the assets utilizing the
straight-line method. The estimated useful lives of the assets are:
buildings -- 20-30 years; leasehold improvements -- the term of the respective
lease or the estimated useful life of the improvements, whichever is shorter;
vehicles -- 3-7 years; equipment and machinery -- 3-7 years; computer software
and hardware -- 3-5 years; and furniture and fixtures -- 5-7 years. Maintenance
and repairs are expensed as incurred; expenditures that enhance the value of the
property or extend its useful life are capitalized. When assets are sold or
returned, the cost and related accumulated depreciation are removed from the
accounts and the resulting gain or loss is included in income.

INVENTORY

     Inventories are stated at the lower of cost, on a first-in, first-out
basis, or market. Inventory consists of items purchased for resale at cost based
on terms of customer contracts. Accordingly, there is no cost other than the
purchase price of the items purchased included in the carrying value.
Substantially all of the Company's inventories can be used in multiple
contracts.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair values of the Company's financial instruments approximate their
recorded values due to the relatively short-terms of the instruments and the
floating interest rate of the Company's debt. CONCENTRATIONS OF CREDIT RISK

     Substantially all of the Company's accounts receivable are due from
companies within the telecommunications industry located throughout the United
States. Credit is extended based on an evaluation of the customer's financial
condition and, generally, collateral is not required. Credit losses are provided
for in the consolidated financial statements.

     The Company maintains various bank accounts and at times, amounts may be in
excess of FDIC insurance limits.

INTANGIBLE ASSETS

     The excess of the purchase price over the fair market value of the tangible
net assets of acquired businesses (goodwill) is amortized on a straight-line
basis over estimated useful lives of 10 to 25 years. The appropriateness of the
carrying value of goodwill is reviewed periodically by the Company at a
subsidiary level. An impairment loss for the difference between fair value and
recorded value is recognized

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

when the projected undiscounted future cash flows are less than the carrying
value of goodwill. No impairment loss has been recognized in the period
presented. Amortization expense was $3,321,242 and $766,953 for the fiscal
periods ending December 14, 1999 and December 31, 1998, respectively. The
intangible assets at December 14, 1999 and December 31, 1998 are net of
accumulated amortization of $4,088,196 and $766,953, respectively.

     Deferred financing costs of $5,471,786 and $1,567,446 at December 14, 1999
and December 31, 1998, respectively, are being amortized over the term of the
related debt facility. For the period ended December 14, 1999 and December 31,
1998, $636,502 and $166,919, respectively, of amortization expense related to
these costs has been included in interest expense.

INCOME TAXES

     Deferred income taxes are provided for the temporary differences between
the financial reporting basis and the tax basis of the Company's assets and
liabilities.

     Prior to the transaction on March 31, 1998, the Company, with the consent
of its stockholder, has elected to be an S corporation under the Internal
Revenue Code. Therefore, no provision or liability for federal and state income
taxes has been included for these periods.

STOCK OPTION PLANS

     In October 1995, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock Based Compensation," which was effective for the Company beginning August
1, 1996. SFAS No. 123 requires expanded disclosures of stock based compensation
arrangements with employees, and encourages, but does not require, compensation
cost to be measured based on the fair value of the equity instrument awarded.
Under SFAS No. 123, companies are permitted, however, to continue to apply
Accounting Principle Board (APB) Opinion No. 25, which recognizes compensation
based on the intrinsic value of the equity instrument awarded. The Company
applies APB Opinion No. 25 to its stock based compensation awards to employees
and properly discloses the required pro forma effect of applying SFAS No. 123 on
net income included in Note 15.

RECLASSIFICATIONS

     Certain amounts presented in the prior year financial statements have been
reclassified to conform to the current year presentation.

4. ACQUISITIONS

     Orius acquired seven companies during 1998 (excluding Channel) for total
consideration of $39.6 million plus transaction related expenses of $1.2
million. The cash paid for acquisitions totaled $27.6 million (net of cash
acquired of $3.0 million) and the value of the common stock issued totaled $11.8
million. Additionally, approximately $7.5 million of debt was assumed. All of
the 1998 acquisitions were accounted for as purchases and were included in the
Company's operations from the dates of acquisition. The total goodwill
associated with these transactions was approximately $27.6 million.

     During 1999, five companies were acquired for total consideration of
$107.75 million plus transaction related expenses of $1.65 million.
Additionally, approximately $7.1 million of debt was assumed. Cash paid for the
four acquisitions totaled $91.9 million (net of cash acquired of $4.8 million)
and the value of common stock issued (2,511,279 shares) totaled $15.8 million.
The purchase price of each acquisition is subject to a customary purchase price
adjustment mechanism. All the 1999 acquisitions were accounted

for as purchases and were included in the results of operations from the date of
acquisition. The goodwill associated with the 1999 acquisitions totaled $78.9
million.

     Pursuant to certain of the purchase agreements, the Company may be required
to give additional consideration of cash and Orius common stock to the former
acquired-company shareholders upon attainment of specified financial criteria
over the periods ended December 31, 1999 and the year ending December 31, 2000.
The amount of shares and cash to be issued cannot be determined until the
periods expire and the attainment of the criteria is established. The Company
accounts for this additional consideration when the specified financial criteria
are achieved and it is probable it will be paid. At December 14, 1999, based
upon the expected attainment of fiscal 1999 targets for certain acquisitions,
additional consideration of $1.5 million has been recorded as additional
purchase price and included as a liability to the former stockholders of the
acquired companies. If targets are achieved in 2000, the Company may be
obligated to pay additional consideration of $2.9 million and issue up to
120,000 shares of common stock.

     Since its commencement of operations, the following acquisitions have been
made by Orius:

     On February 26, 1999, NATG Holdings entered into a new credit agreement
with Merrill Lynch, Pierce Fenner & Smith Incorporated and PNC Bank, National
Association ("PNC"), as joint lead arrangers and a new syndication of banks
("New Credit Agreement"). The New Credit Agreement, which was amended on May 24
and September 23, 1999, includes a $50.0 million revolving credit facility,

maturing in five years, and a $168.5 million senior secured term loan credit
facility. The term loan facility is allocated among a $95.5 million Term A
facility, maturing on December 1, 2003; a $58 million Term loan B facility,
maturing of December 1, 2004; and a $15 million Term loan C facility, maturing
on December 1, 2005. NATG Holdings borrowed under the New Credit Agreement to
complete its acquisitions in February and May 1999 and to repay substantially
all indebtedness of NATG, and terminate all commitments to make extensions of
credit to NATG, under NATG's old credit facility with PNC.

     Amounts under the revolving credit facility and term loan facility bear
interest, at NATG Holdings' choice, at either LIBOR plus an applicable margin or
the higher of PNC's corporate base rate of interest or the Federal Fund Rate
plus 0.50% (the "ABR"), in each case plus an applicable margin. For LIBOR loans,
the margin is 3.00% for the revolving credit facility and Term loan A facility,
3.75% for the Term loan B facility and 5.00% for the Term loan C facility. For
ABR loans, the margin is 2.00% for the revolving facility and Term loan A
facility, 2.75% for the Term loan B facility and 4.00% for the Term loan C
facility. Outstanding amounts under the revolving credit facility and term loan
facility are secured by substantially all of NATG Holdings' assets and the
pledge of all the outstanding shares of common stock of each of Orius' direct
and indirect subsidiaries, including NATG. The credit facility also contains
affirmative and negative covenants relating to NATG Holdings' operations.

     As a result of the termination and repayment of the indebtedness

JUNIOR SUBORDINATED CONVERTIBLE NOTE

     On March 31, 1998, the Company sold to HIG a $1,000,000, 9% junior
subordinated convertible note, due April 15, 2005 (the Junior Convertible Note).
The debt may be converted at any time, at the option of HIG or at the Company's
option upon an initial public offering, into 692,627 shares of the Company's
common stock. As further discussed in Note 10, the Company and HIG entered into
a redemption agreement that gives HIG certain rights to put its converted common
stock to the Company. Due to the conversion feature of the Junior Convertible
Note coupled with the redemption rights of HIG, the liability

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

associated with the Junior Convertible Note is adjusted at each balance sheet
date to the greater of the principal plus interest due or the fair market value
of the converted common stock. At December 14, 1999, the fair market value of
the common stock is estimated at $13.38 per share. Accordingly, the liability
for the Junior Convertible Note is recorded at $9,267,349. The amount
attributable to the accretion to the fair value of the converted common stock
for the periods ended December 14, 1999 and December 31, 1998 of $8,923,991 and
$493,358, respectively, is recorded as a reduction of retained earnings and on a
separate line in the balance sheet. The interest charge for the periods ended
December 14, 1999 and December 31, 1998 totaled $90,000 and $63,500,
respectively and was recorded as interest expense.

9. CONVERTIBLE PREFERRED STOCK

     During 1998, The company issued 10,000 shares of Series A Convertible
Preferred Stock (Series A Preferred) to HIG for $4,438,500, net of $61,500 of
issue costs. The Series A Preferred has an 8% cumulative dividend, is
convertible to shares of Orius common stock, has full voting rights on an as-if
converted basis and its conversion is at the discretion of HIG. Further, HIG was
given certain redemption rights discussed in Note 10. In connection with the
Reorganization discussed above, the number of shares of common stock into which
the Series A Preferred was convertible was changed to 3,116,828. At December 14,
1999 and December 31, 1998, the total recorded value of the Series A Preferred
has been determined based upon the convertible common shares into which the
Series A Preferred was convertible as of those dates at $2.34 per common share
and $13.38 per common share, respectively. The 1998 per common share price was
based upon the pricing of the February 26, 1999 Series B Convertible Preferred
Stock discussed below and the value of the common stock used in the December 15,
1999 transaction with LISN Holdings, Inc. discussed in Note 19. The accretion to
estimated fair value and dividends during the periods ended December 14, 1999
and December 31, 1998 was $34,993,495 and $2,902,149, respectively.

     In connection with the acquisitions on February 26, 1999, HIG Cable West,
Inc. purchased 7,596.38 shares of Series B Convertible Preferred Stock (Series B
Preferred) for $7,569,377. The Series B Preferred has the same rights as the
Series A Preferred and may be converted into 3,252,290 shares of Orius Corp.
common stock. At December 14, 1999, the recorded value of the Series B Preferred
has been determined based upon the converted common shares of 3,252,290 at
$13.38 per share, or $43,515,640. The accretion to estimated fair value and
dividends from February 26, 1999 to December 14, 1999 totaled $36,434,063.

10. HIG REDEMPTION RIGHTS

     The Company entered into a redemption agreement on March 31, 1998 with HIG
(the Redemption Agreement) that allows HIG to redeem its converted shares of
common stock derived from the Series A and Series B Preferred and Junior
Convertible Note. Pursuant to the Redemption Agreement, HIG may cause the
Company to redeem its converted shares of common stock at the earlier of a sale
of the Company, a merger involving the Company, commencement of liquidation or
bankruptcy proceedings, or April 15, 2005. Conversion can only occur for all of
the shares of Preferred Stock at once and the junior Convertible Note must be
converted at the same time. The redemption value of the converted shares of
common stock is the greater of fair market value at the date of redemption or
the initial purchase price for the Preferred Stock and junior Convertible Note
plus any accumulated and unpaid dividends and interest. In the event of an
initial public offering of Orius common stock, HIG's redemption rights are
terminated.

11. WARRANTS TO PURCHASE COMMON STOCK

     In connection with entering the new credit agreement on February 26, 1999,
the Company issued to the joint lead arrangers and certain of the banks that
participated in the new credit agreement warrants to

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY NATG HOLDINGS, INC.)

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

purchase a total of 371,853 shares of common stock. The warrants expire March
31, 2009 and entitle the holders to purchase common stock for $.01 per share.
The warrants are exercisable any time after the consummation of an initial
public offering, September 30, 2003 or in the event of a merger or other change
of control.

     The estimated fair market value of the warrants at the date of issuance of
$868,538 has been reflected in the separate component of stockholders' equity
entitled warrants. An offsetting amount has been reflected as a discount or
reduction of the Company's long-term debt. The $858,538 of discount is being
recognized as interest expense using the effective interest method over 66
months which is the weighted average life of the credit agreement components
including the full capacity of the revolver and the Term A, B and C loans.

12. ISSUANCE OF COMMON STOCK

     On February 26, 1999, the Company issued to certain of its then existing
stockholders 1,029,079 shares of common stock in exchange for cash of
$2,403,623.

13. INCOME TAXES

     Effective January 1, 1997, Channel elected to be treated as an S
corporation for income tax purpose as allowed under the Internal Revenue Code.
With this conversion, the Company's net deferred tax balance of $220,276 was
reversed as a credit to the provision for income taxes. The tax liabilities for
the year ended December 31, 1997 were the responsibility of the individual
shareholder. In connection with the transaction on March 31, 1998, the Company's
S corporation status was terminated. With this termination, the Company was
required to recognize a deferred tax liability and corresponding charge to
income of $330,254 with payment to be spread over four years.

     The components of the provision for income taxes for the periods ended
December 14, 1999 and December 31, 1998 are as follows:

14. EMPLOYEE BENEFIT PLANS

     Certain subsidiaries of the Company have defined contribution plans that
provide retirement benefits to all employees that elect to participate. Under
the plans, participating employees may defer up to 15% of their base pre-tax
compensation. Generally, the Company's contributions to the plans are
discretionary.

15. STOCK OPTION PLANS

     The Company has reserved 518,045 shares of common stock under its 1998
Incentive Stock Option Plan (the "Plan") which was approved by the stockholders
on March 30, 1998. The Plan provides for the granting of options to key
employees. Options are exercisable over a period of 10 years. A summary of the
status of the Plan as of December 14, 1999 and December 31, 1998 and the changes

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Grants of options under the plan are accounted for using the intrinsic
value method. Accordingly, no compensation cost has been recognized for grants
made to date. There would have been no difference in net income for the period
ended December 31, 1998 had compensation cost been determined under the
provisions of SFAS 123 regarding the minimum fair value of each grant. For
purposes of this calculation in 1998, the fair value of each option grant is
estimated as of the date of grant using the Black-Scholes option pricing model.
The weighted-average assumptions used in determining fair value as disclosed for
SFAS 123 were risk-free interest rates ranging from 5.0% to 5.7% and an option
life of six years. There would have been no difference in net income for the
period ended December 14, 1999 because the Company accelerated the vesting of
all options in connection with the transaction discussed in Note 19. As a result
of the acceleration, compensation expense of $5,814,000 was recognized and that
amount would have been approximately the same under SFAS No. 123.

16. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK

     The operating subsidiaries obtain contracts from both public and private
concerns. For the periods ended December 14, 1999 and December 31, 1998, and
1997 approximately 36%, 56%, and 72%, respectively, of the contract revenues
were from three customers (TCI, Time Warner, and MediaOne), with the largest
customer representing approximately 16% and 24%, for the two most recent
periods, respectively, of the contract revenues.

     Financial instruments, which potentially subject the Company to
concentrations of credit risk, consist principally of trade accounts receivable.
The three customers noted above represent a significant portion of the Company's
customer base. As of December 14, 1999 and December 31, 1998, the total
outstanding trade receivables from these customers was approximately $37.4
million and $13 million, respectively, or 38% and 50%, respectively, of the
Company's outstanding trade receivables.

17. COMMITMENTS AND CONTINGENCIES

     The Company and its subsidiaries have entered operating leases covering
office facilities, vehicles and equipment that have non-cancelable terms in
excess of one year. Certain of these leases contain renewal provisions and
generally require the Company to pay insurance, maintenance, and other operating
expenses. Total expense incurred under operating lease agreements for the
periods ended December 14, 1999 and December 31, 1998 and 1997, were
approximately $4,325,647, $1,183,300 and $352,913, respectively.

18. RELATED PARTY TRANSACTIONS

     Certain subsidiaries of the Company lease administrative offices from
partnerships and corporations of which certain officers of the subsidiaries are
the general partners or shareholders. The total expense under these arrangements
was $1,145,747 during the period ended December 14, 1999. The future minimum
lease commitments under these arrangements are $700,814 in 2000, $365,140 in
2001, $329,140 in 2002 and 2003 and $55,028 in 2004.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors of Orius Corp.

     In our opinion, the accompanying balance sheets and the related statements
of operations and of cash flows present fairly, in all material respects, the
financial position of U.S. Cable, Inc. at September 30, 1997 and June 30, 1998,
and the results of its operations and its cash flows for the year ended
September 30, 1997 and the nine months ended June 30, 1998 in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audits 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

                       THE YEAR ENDED SEPTEMBER 30, 1997
                     AND FOR THE PERIOD ENDED JUNE 30, 1998

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of certain significant accounting policies
followed in the preparation of the financial statements.

PRINCIPAL ACTIVITIES

     U.S. Cable, Inc. (the "Company,") incorporated on December 12, 1963, is a
cable installation contractor for cable companies throughout the United States.
During the course of its business, the Company grants unsecured credit to its
customers.

BASIS OF ACCOUNTING

     The Company's policy is to prepare its financial statements on the accrual
basis of accounting.

REVENUE RECOGNITION

     Revenue is recorded as units and footages are actually installed. If the
unit price of a contract is determined to be below estimated cost, the entire
estimated ultimate loss is accrued.

DEFERRED BILLINGS

     Deferred billings consist of unbilled accounts receivable for work
performed prior to the balance sheet date. All costs associated with the
deferred billings are also recognized as expenses as of the balance sheet date.

ACCOUNTS RECEIVABLE

     Accounts receivable include amounts that represent retainage on contracts
which is collectible at the conclusion of the contracts. Retainage included in
the accounts receivable balance totaled $288,770 and $607,200 as of September
30, 1997 and June 30, 1998, respectively. Historically, the Company has not
experienced any significant bad debts or pricing adjustments and, accordingly,
there is no provision for bad debts or other allowances recorded as of any
balance sheet date.

CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include all highly liquid investments purchased
with original maturities of three months or less.

INVENTORY

     Inventory is stated at the lower of cost, on a first-in, first-out (FIFO)
basis, or market. Inventory consists primarily of purchased materials used in
the installation of cable systems.

PROPERTY AND EQUIPMENT

     Property and equipment are recorded at cost less accumulated depreciation.
Depreciation is computed using various accelerated and straight-line methods.
Repairs and maintenance charges which do not increase the useful lives of the
assets are charged to expense as incurred. Upon sale or retirement, the cost and
related accumulated depreciation are eliminated from the respective accounts and
resulting gain or loss included in other income.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

TREASURY STOCK

     The Company's common stock is no par value. When common stock is
repurchased, it is recorded as treasury stock at the cost of repurchase. When
treasury stock is sold, treasury stock is reduced by the lesser of the sale
price or original cost with any excess proceeds over cost used to increase
common stock. All treasury stock was retired during the period ended June 30,
1998.

INCOME TAXES

     Income taxes are provided for the tax effects of transactions reported in
the financial statements and consist of taxes currently due plus deferred taxes.
Deferred taxes, which have not been material, are recognized for differences
between the basis of assets and liabilities for financial statement and income
tax purposes.

FAIR VALUES OF FINANCIAL INSTRUMENTS

     The fair values of the Company's financial instruments approximate the
carrying values due to their short-term maturities.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates and such
differences may be material to the financial statements.

     Estimates are used in the Company's revenue recognition of work-in-process,
costs associated with the work-in-progress, allowances for doubtful accounts,
depreciation and amortization, and in the estimated lives of assets.

NOTE 2 -- STATEMENT OF CASH FLOWS

     For the purpose of the statement of cash flows, the Company considers all
highly liquid debt instruments purchased with an original maturity of three
months or less to be cash equivalents.

                         NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     DAS-CO of Idaho, Inc. (the Company) is primarily engaged in the business of
installing underground utility, telephone, and cable transmission lines. The
Company is headquartered in Nampa, Idaho, and has offices in Twin Falls and
Pocatello, Idaho. The Company performs work under contracts with utility and
communications companies primarily in the Western United States.

     On February 26, 1999 (the "acquisition date"), the Company was sold to
North American Tel-Com Group, Inc.(NATG) headquartered in West Palm Beach,
Florida, (the acquisition).

     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
and such differences may be material to the financial statements.

     Revenue: Revenues from contracts are recognized as the related costs are
incurred based on the relationship of costs incurred to total estimated contract
costs. Unbilled accounts receivable for contracts-in-process represents revenue
recognized but not billed. Deferred revenue represents billings on contracts for
which costs have not yet been incurred and revenue has not been recognized. At
the time a loss on a contract becomes known, the entire amount of the estimated
loss is accrued.

     Cash and cash equivalents: Cash and cash equivalents include cash balances
on deposit with banks, overnight repurchase agreements, and various other
financial instruments purchased with a remaining maturity of three months or
less. At times, balances on deposit with banks may exceed amounts insured by the
Federal Deposit Insurance Corporation.

     Inventory: Inventories are stated at the lower of cost, on a first-in,
first-out basis, or market.

     Property and Equipment: Property and equipment is stated at cost.
Depreciation and amortization is computed over the estimated useful life of the
assets utilizing the straight-line method. The estimated useful lives of the
assets are: leasehold improvements -- the term of the respective lease or the
estimated useful life of the improvements, whichever is shorter; vehicles -- 5
years; equipment and machinery -- 5 years; computer equipment -- 3-5 years; and
other equipment -- 10 years. Maintenance and repairs are expensed as incurred;
expenditures that enhance the value of the property or extend its useful life
are capitalized. When assets are sold or retired, the cost and related
accumulated depreciation are removed from the accounts and the resulting gain or
loss is included in income.

     Income Taxes: Prior to the acquisition date, the Company was an S
corporation for income tax purposes, and accordingly, any income tax liabilities
for the periods prior to acquisition were the responsibility of the respective
stockholders.

     Subsequent to the acquisition date, the Company became part of the
consolidated group for federal income tax purposes.

5. PROFIT SHARING PLAN:

     The Company sponsors a 401(k) profit sharing plan covering substantially
all full-time employees. Company discretionary contributions to the plan totaled
$16,667, $100,000 and $100,000 for 1999, 1998 and 1997, respectively.

6. TRANSACTIONS WITH RELATED PARTY:

     During 1999, the Company leased office and shop facilities from businesses
owned by a related party on a month-to-month basis. On February 26, 1999 these
lease agreements were restructured to require minimum annual lease payments of
$168,744 for each of the next five years. Rental expense for these leases
totalled $169,200, $155,000 and $28,124 for 1997, 1998 and 1999, respectively.

7. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK:

     In 1999, revenues from two customers represented approximately 67% and 21%;
in 1998, revenues from three customers represented approximately 41%, 13%, and
12% of total revenue; and in 1997, revenues from three customers represented
approximately 50%, 16%, and 15% of total revenue.

     Financial instruments, which potentially subject the Company to
concentrations of credit risk, consist principally of cash and cash equivalents
and accounts receivable. The Company grants credit, generally without
collateral, to its customers, which include utility companies,
telecommunications providers and commercial companies located primarily in the
Western United States. Consequently, the Company is subject to potential credit
risk related to changes in business and economic factors throughout the Western
United States.

8. CONTINGENCIES AND COMMITMENTS:

     The company is subject to lawsuits and other legal claims in the normal
course of its operations. Management believes that the resolution of any such
lawsuits and legal claims, if any, will not have a material impact on the
Company's financial position, results of operations or cash flows.

9. SALE OF COMMON STOCK

     On February 26, 1999 the Company's shareholders entered into a stock
exchange agreement with NATG. Pursuant to the agreement, all the shares of the
Company's common stock were exchanged for cash and shares of NATG common stock.
The financial statements of the Company as of and for the period ended February
26, 1999 do not reflect the share exchange agreement.

ACCRUED HEALTH INSURANCE

     During 1997 and through May 31, 1998, employees and their dependents were
provided comprehensive health care coverage under a self-funded plan. The
Company pays the first $50,000 in medical expenses per covered individual per
year. Any additional costs are paid by the Plan's underwriters. Premiums due the
underwriters are accrued and paid monthly. The Company's self-funded liability
is accrued based on actual claims filed. The reserve liability for accrued
health insurance benefits payable was $52,466 at December 31, 1997. The Company
ceased to be self-funded on June 1, 1998 and paid all remaining self-funded
liability; therefore, no liability exists at December 31, 1998.

USE OF ESTIMATES

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.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amount of financial instruments have been estimated by
management to approximate fair value.

ADVERTISING

     The costs of advertising are expensed as incurred.

1997 and August 31, 1998, and the results of its operations and its cash flows
for the year ended December 31, 1997 and the eight months ended August 31, 1998,
in conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of certain significant accounting policies
followed in the preparation of the financial statements.

COMPANY'S ACTIVITIES

     CATV Subscriber Services, Inc. (the Company), incorporated in North
Carolina in March 1972, is a provider of infrastructure services to cable
television system operators.

BASIS OF ACCOUNTING

     The Company's policy is to prepare its financial statements on the accrual
basis of accounting. The consolidated financial statements include the accounts
of CATV Subscriber Services, Inc., and its wholly owned inactive subsidiary,
Arizona Cable Concepts, Inc. Intercompany accounts have been eliminated.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates and such
differences may be material to the financial statements.

     Estimates are used in determining the Company's revenue recognition of
work-in-progress, costs associated with the work-in-progress, allowances for
doubtful accounts, depreciation and amortization, and in the estimated useful
lives of assets.

REVENUE RECOGNITION

     Revenue is recorded as units and footages are actually installed. If the
unit price of a contract is determined below cost, the entire estimated ultimate
loss is accrued.

DEFERRED BILLINGS

     Deferred billings consist of unbilled accounts receivable on work performed
prior to December 31, 1997 and August 31, 1998. All costs associated with the
deferred billings are also recognized as expenses as of the balance sheet date.

ACCRUED COSTS IN EXCESS OF BILLINGS

     Accrued costs in excess of billings represents estimated cost required to
complete the current units of production in excess of amounts billed for those
units of production.

CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include all highly liquid investments purchased
with original maturities of three months or less.

INVENTORY

     Inventory is stated at the lower of cost, on a first-in, first-out (FIFO)
basis, or market, and consists of materials purchased for installation of cable
television networks.

                 CATV SUBSCRIBER SERVICES, INC. AND SUBSIDIARY

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

PROPERTY AND EQUIPMENT

     Property and equipment are recorded at cost less accumulated depreciation.
Depreciation is computed using various accelerated and straight-line methods for
income tax and financial statement purposes. Repairs and maintenance charges
which do not increase the useful lives of the assets are charged to expense as
incurred. Upon sale or retirement, the cost and related accumulated depreciation
are eliminated from the respective accounts and resulting gain or loss included
in current income.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair values of the Company's financial instruments approximate their
carrying value due to the short-term maturities of these financial instruments.

INCOME TAXES

     Income taxes are provided for the tax effects of transactions reported in
the financial statements and consist of taxes currently due plus deferred taxes.
Deferred taxes are recognized for differences between the basis of assets and
liabilities for financial statement and income tax purposes. The differences
relate primarily to depreciable assets (use of different depreciation methods
and lives for financial statement and income tax purposes) and certain reserves
recorded for book purposes that are not currently deductible for tax purposes.
The deferred tax assets and liabilities represent the future tax return
consequences of those differences, which will either be taxable or deductible
when the assets and liabilities are recovered or settled.

NOTE 2 -- STATEMENT OF CASH FLOWS

     For the purpose of the statement of cash flows, the Company considers all
highly liquid debt instruments purchased with an original maturity of three
months or less to be cash equivalents.

</TABLE>

     Retainage consists of amounts that are not due until the completion of a
contract. The allowance for doubtful accounts was increased by $997,374 during
1998 for the write-off of receivables from St. Martin Cable TV, FWI, (SMCTV).
The Company filed a claim against SMCTV in mid-1997 and has received only
insignificant payments since that time. During 1988, the Company elected to not
pursue the collection of the receivable due to costs associated with doing so.

Martin receivable are included in prepaid expenses and other current assets as
of August 31, 1998. The deferred tax liabilities of $159,093 and $188,947 at

     In our opinion, the accompanying balance sheets and the related statements
of operations, changes in shareholder's equity and of cash flows present fairly,
in all material respects, the financial position of TEXEL Corporation (the
Company) as of December 31, 1997 and 1998, and the results of its operations and
its cash flows for each of the two years in the period ended December 31, 1998,
in conformity with generally accepted accounting principles. These financial
statements are the responsibility of management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

     In our opinion, the accompanying balance sheet and the related statement of
operations, changes in shareholder's equity and of cash flows present fairly, in
all material respects, the financial position of TEXEL Corporation (the
"Company") at May 24, 1999, and the results of its operations and its cash flows
for the period from January 1, 1999 through May 24, 1999, in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these statements in accordance with
auditing standards generally accepted in the United States which 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, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for the opinion expressed above.

                               TEXEL CORPORATION

                         NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION

     Texel Corporation (the "Company") was incorporated in 1983 under the laws
of the Commonwealth of Virginia. The Company is a provider of premise wiring
services, primarily in the Washington, D.C. metropolitan area. The Company's
corporate headquarters are located in Reston, Virginia and as of April 30, 1999,
the Company had two regional field offices in Columbia, Maryland and Richmond,
Virginia.

     Effective May 25, 1999 all of the Company's outstanding shares were sold to
Orius Corporation. See subsequent event Note 11.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CONTRACT REVENUE

     The Company recognizes revenue from contracts in process on the percentage
of completion method of accounting based on contract costs incurred to date
compared with total estimated contract costs. Contract costs include all direct
labor, material, subcontract, depreciation, and other direct project costs
related to contract performance. General and administrative costs are charged to
expense as incurred.

     Service revenue is recognized when the work is complete. This work is
primarily short term and completed within five days or less.

     Revenues recognized in excess of amounts billed are classified as current
assets under costs in excess of billings, and amounts billed in excess of
revenues recognized to date are classified as current liabilities as billings in
excess of costs. Contract retentions are included in accounts receivable.

     Included in accounts receivable are unbilled amounts which represent
revenue billable for completed contracts. Such amounts were billed within 60
days of year end.

INCOME TAXES

     The Company elected subchapter S-Corporation status effective January 1,
1984. As an S-Corporation, the shareholder reports profits or losses of the
Company, for Federal and State income tax purposes, on his individual income tax
return. As an S-Corporation, the Company was not subject to certain income taxes
at the corporate level. Substantially all payments made to the shareholder are
in the form of S-Corporation shareholder distributions. In conjunction with the
sale of the Company's outstanding stock, the Company's S-Corporation filing
status will be terminated and the Company will begin to be taxed as a
C-Corporation for federal and state income tax purposes. Pro forma income taxes
are calculated at a combined federal and state tax rate of 38%.

CASH AND CASH EQUIVALENTS

     Cash equivalents are highly liquid short-term investments readily
convertible into cash. Cash equivalents consist primarily of time deposits and
certificates of deposit with various financial institutions. These investments
are carried at cost, which approximates market and mature within 90 days and
therefore are subject to minimal risk.

PROPERTY AND EQUIPMENT

     Property and equipment is recorded at cost. The cost of assets sold or
retired and the related amounts of accumulated depreciation are eliminated from
the accounts and the resulting gain or loss is included in the income. Renewals
and betterments are capitalized. Repairs and maintenance are charged to expense
when incurred.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     Depreciation is computed using the straight-line and accelerated methods
over the following estimated useful lives:

<TABLE>
<S>                                                           <C>
Furniture and fixtures......................................   7.5 years
Machinery and equipment.....................................   5.5 years
Automobiles.................................................   5.5 years
Computer software...........................................   5.5 years
</TABLE>

     Leasehold improvements are amortized over the shorter of the life of the
lease or the life of the asset. Such periods generally approximate seven years.

     Depreciation expense in 1997, 1998 and 1999 was $83,767, $101,434 and
$51,185 respectively.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of the Company's assets and liabilities approximate
fair value due to the short-term maturity of these financial instruments.

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 amounts could differ from these estimates.

3. MAJOR CUSTOMERS

     Sales to individual customers representing more than 10% of total sales
were approximately $5,933,000, $11,246,000 and $4,159,000 in 1997, 1998 and
1999, respectively. These amounts represent sales to 2 customers in each year.

4. ACCOUNTS RECEIVABLE

7. LEASE COMMITMENTS

     The Company leases office space at various locations under noncancelable
operating leases expiring through 2005. Each lease agreement provides for an
annual escalation of 3%.

     Certain office space is leased from Trison LLC, a real estate company owned
by the sole shareholder of the Company. The lease requires monthly payments of
approximately $33,000 over a 7-year term, with a 5-year renewal option. Based on
the terms of the lease, the Company received 10-month rent abatement in return
for making necessary leasehold improvements to the office space. The rent
abatement is recognized on a straight line basis over the term of the lease.
Rent expense for office space for the year ended December 31, 1998 was $307,323.

     Minimum rental payments due under noncancelable operating leases are as
follows:

                         NOTES TO FINANCIAL STATEMENTS

                        DECEMBER 31, 1999, 1998 AND 1997

NOTE 1 -- ORGANIZATION AND BUSINESS

     Hattech, Inc. (the Company) was incorporated in the Commonwealth of
Virginia on January 23, 1995. The Company provides engineering and installation
of telecommunications equipment services to customers throughout the United
States.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH

     For purposes of the statement of cash flows, cash consists of demand
deposits held in banks.

     The Company maintains its cash in bank deposit accounts which, at times,
may exceed federally insured limits. The Company believes it is not exposed to
any significant credit risk for amounts in excess of the insured limits.

ACCOUNTS RECEIVABLE

     The Company maintains its books and records on the accrual basis of
accounting. Accounts receivable are reported at their gross value, less an
allowance for doubtful accounts as deemed necessary. The allowance for doubtful
accounts was $5,149 at December 31, 1999. There was no allowance for doubtful
accounts at December 31, 1998 and 1997. Unbilled accounts receivable consist
primarily of sales to customers which cannot be billed until the project is
substantially complete.

REVENUE RECOGNITION

     Revenue on time and material contracts is recognized on the basis of
billable rates times hours delivered plus materials expense incurred. Revenue on
fixed-price contracts is recognized on the basis of percentage-of-completion
using a method which approximates costs incurred in relation to the estimated
costs. Losses on contracts are provided for in the period in which they are
first determined.

     Because of inherent uncertainties in estimating costs, it is at least
reasonably possible that the estimates used will change within the near term.

INVENTORY

     Inventory is stated at the lower of cost or market. Cost is determined
using the first-in, first-out (FIFO) method. The Company's inventory is
comprised primarily of materials and cable.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Property and equipment under
capital leases are stated at the lower of the present value of minimum lease
payments at the beginning of the lease term or fair value of the property at the
inception of the lease.

     Depreciation on property and equipment is calculated using the
straight-line and accelerated methods over the estimated useful lives of the
assets, generally 3 to 10 years. Property and equipment held under capital
leases which contain a bargain purchase option or transfer of ownership are
depreciated in the same manner described above. Leasehold improvements are
amortized using the straight-line method over the shorter of the lease term or
estimated useful life of the asset.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

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.

INCOME TAXES

     The Company elected to be taxed as an "S" Corporation effective January 1,
1996 under the Internal Revenue Code. Consequently, in lieu of corporate income
taxes, the stockholders are taxed on their proportionate share of the Company's
taxable income.

NOTE 3 -- INVESTMENT

     The Company had a 42% interest as a general partner in a joint venture that
designed and installed telecommunication equipment for customers overseas. The
joint venture is reflected on the accompanying balance sheets at December 31,
1998 and 1997 using the equity method of accounting.

     The Company and its partner in the joint venture were in litigation over
the value of the Company's interest in the joint venture. The litigation was
settled during 1999. As part of the settlement, the Company received $50,000 and
the joint venture was dissolved.

NOTE 4 -- PROPERTY AND EQUIPMENT

     Property and equipment consists of the following at December 31:

NOTE 9 -- CONCENTRATIONS

     The Company was the primary provider of field engineering and installation
services for one of its customers. The Company also provided warehouse and
staging facility services for the customer. The services were provided pursuant
to a Services Agreement that commenced February 1, 1998 and terminated February
1, 2000.

     Revenue generated from this customer comprised approximately 70%, 97% and
100% of total revenue for the years ended December 31, 1999, 1998 and 1997,
respectively. Approximately 58%, 90% and 100% of billed and unbilled accounts
receivable at December 31, 1999, 1998 and 1997, respectively, are due from this
customer.

     Two other customers had balances that approximated 15% and 11% of total
accounts receivable at December 31, 1999.

     The Company obtains the majority of its inventory from two suppliers.
Although no formal purchase agreement exists, the Company believes the
relationships will continue.

     The Company has an agreement effective July 1, 1997 with a union that
covers approximately 39% of the Company's labor force in 1999. The agreement
terminates on June 30, 2002.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 10 -- PROFIT SHARING

     The Company amended its 401(k) Profit Sharing Plan (the Plan) in 1999 and
1998 to eliminate minimum age and length of service requirements. The Plan
allows eligible employees to defer a portion of their annual compensation,
subject to the limits in Section 401(k) of the Internal Revenue Code. The
Company, at its discretion, may make profit sharing contributions to the Plan.
Such contributions vest ratably over a five year period. The Company made profit
sharing contributions of $150,000 and $81,219 in 1999 and 1998, respectively.

NOTE 11 -- EMPLOYEE STOCK BASED COMPENSATION

     The Company adopted an Employee Stock Based Compensation Agreement in
December 1999. The agreement entitles participants to receive compensation in
the form of "stock based compensation units," as defined in the agreement. The
board of directors, at its discretion, grants "stock based compensation units."
The agreement provides for ratable vesting over a five-year period.

     The value of each "stock based compensation unit" is determined at the end
of each fiscal year through the year ending December 31, 2003, at which time the
final value of the "stock based compensation units" will be determined. The
value of each "stock based compensation unit" is determined by a formula defined
in the agreement.

     In the event that there is a change in control transaction, as defined in
the agreement, prior to December 31, 2003, participants will be entitled to
receive their vested portion of the "stock based compensation units" within 60
days of the change in control. Participants that remain with the Company after a
change in control will continue to receive compensation equal to the amount they
would have received, on each vesting date, had there not been a change in
control.

     The value of the "stock based compensation units" at December 31, 1999 was
$46,999 and is included in the accompanying financial statements as an expense
and a liability.

NOTE 12 -- 1998 FINANCIAL STATEMENTS RESTATED

     Certain errors, resulting in the overstatement of reported net income in
the Company's previously issued 1998 unaudited financial statements, have been
corrected as a result of the audits for the years ended December 31, 1998 and

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

THE COMPANY

     Copenhagen Utilities & Construction, Inc. (the "Company,") an Oregon
corporation since 1975, operates in Oregon, Washington, California and Nevada.
The Company is a provider of installation, design, engineering and maintenance
services for the telecom industry. The Company also provides installation
services for gas and water utilities. The Company is located in Clackamas,
Oregon and Sacramento, California.

     These financial statements include the accounts of a special purpose
entity, Excel Equipment LLC, and is owned by the same shareholders as the
Company. On December 31, 1998, in preparation for the sale of the outstanding
shares of stock of the Company as discussed in Note 13, substantially all assets
of Excel were transferred to the Company, and the Company assumed a portion of
the Company's long-term debt. In connection with this transfer amounts owing
related entities by Excel totaling $542,234 was not assumed by the Company and
accordingly, was recorded as a contribution of capital.

     Following is a summary of the Company's significant accounting policies:

CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments with a maturity of
three months or less at date of purchase to be cash equivalents. The cost of
these investments approximates fair value. At times, temporary cash investments
may be in excess of the Federal Deposit Insurance Corporation insurance limit.
The Companies deposits in high credit quality investments with reputable
financial institutions.

SHORT-TERM INVESTMENTS

     Short-term investments are stated at fair market value as of the balance
sheet date. Unrealized holding gains or losses are reported in the balance sheet
as a separate component of stockholders' equity until realized. Realized gains
and losses are included in operations.


     The Company reported no unrealized gains or losses as the market value of
short-term investments approximated their cost at December 31, 1997 and 1998 and
February 26, 1999.


ACCOUNTING FOR LONG-TERM CONTRACTS

     The accompanying financial statements have been prepared using the
percentage-of-completion method of accounting for long-term contracts. This
accounting method provides for the recognition of revenue on contracts which are
not yet completed. The amount of revenue recognized is based on the percentage
that contract costs incurred to date bear to estimated total contract costs,
except that anticipated losses are recognized in their entirety without
reference to percentage-of-completion. Contract costs include all subcontracts,
direct labor and benefits, materials and allocated equipment and indirect costs.

     The Company allocates equipment and indirect costs to each contract based
on equipment usage and direct labor rates. These rates are reviewed and adjusted
periodically to reflect changes in the Company's total equipment and indirect
costs.

     Revisions in estimated costs and earnings are reported in the accounting
period in which the facts requiring revisions become known.

     Profits and losses from service and minor installation contracts are
recognized in the period the work is completed.

OPERATING CYCLE

     Assets and liabilities related to long-term contracts are included in
current assets and current liabilities in the accompanying balance sheets as
they will be liquidated in the normal course of contract completion, although
this may require more than one year.

VEHICLES, EQUIPMENT AND LEASEHOLD IMPROVEMENTS

     Vehicles, equipment and leasehold improvements are stated at cost.
Maintenance and repairs of a routine nature are charged to operations as
incurred; additions and improvements are capitalized. Gains and losses from
sales or retirements are included in operations.

     Depreciation is computed by accelerated methods over the estimated useful
lives of the related assets, which are as follows:

<TABLE>
<S>                                                           <C>
Construction vehicles and equipment.........................       5 years
Office furniture and equipment..............................  5 to 7 years
Leasehold improvements......................................      15 years
</TABLE>

     Amortization of leasehold improvements is classified as depreciation
expense for financial reporting.

INCOME TAXES

     Deferred income taxes are provided for the expected future income tax
effect of differences between the tax basis of assets and liabilities and their
financial reporting amounts. At the balance sheet date, based on enacted tax
laws and statutory tax rates applicable to the years in which the differences
are expected to affect taxable income. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount expected to be realized.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect certain reported amounts and disclosures 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.

CONCENTRATIONS OF CREDIT RISK

     The Company's cash and accounts receivable subject the Company to
concentrations of potential credit risk. The Company limits its risk by
depositing cash only with established financial institutions which maintain high
credit standings. The Company limits its exposure to losses on accounts
receivable by maintaining a broad customer base and performing the majority of
its contracts for public agencies.


     The Company has a long-term service contract to provide service for one
major customer. The Company had total revenues of $16,521,016, $15,219,596 and
$1,648,875 for fiscal years 1997 and 1998 and the period January 1, 1999 through
February 26, 1999, which comprises approximately 34.2%, 43.5% and 42.5%,
respectively.


2. SHORT-TERM INVESTMENTS:


     Short-term investments at December 31, 1997 and 1998 and February 26, 1999
consist of municipal bonds with an approximately 5.60% effective annual yield.
The market value of these investments approximated cost.

10. EMPLOYEE BENEFIT PLANS:

RETIREMENT PLANS:


     The Company's hourly field employees and certain salaried employees
participate in a multi-employer money purchase pension plan sponsored by the
Associated General Contractors of America, Inc. Contributions charged to
operations under this plan totaled approximately $683,000, $604,000 and $34,000
for 1997 and 1998 and the period January 1, 1999 through February 26, 1999,
respectively.



     The Company maintains a defined contribution retirement plan under
provisions of Internal Revenue Code Section 401(k) for its eligible employees
not covered by the money purchase pension plan described above. The plan
requires the Company to match 50% of employee contributions, to a maximum
Company contribution of 3% of the employee's annual compensation (up to
specified limits set by law). The plan also allows for discretionary
contributions to be determined annually by the Company's Board of Directors.
Contributions charged to operations under this plan totaled approximately,
$64,000, $54,000, and $7,000 for the years ended December 31, 1997 and 1998 and
the period January 1, 1999 through February 26, 1999, respectively.


INCENTIVE BONUS PLAN:


     The Company has an incentive bonus plan for certain key employees under
which the employees can share in profits which the Company earns in excess of
predetermined norms. Bonuses earned under this formula have been paid or accrued
as of year-end. Bonuses paid by the Company were $4,035,000 and $5,218,500
during fiscal years 1997 and 1998, respectively. No bonuses were paid or accrued
for the period January 1, 1999 through February 26, 1999.


11. RECAPITALIZATION:

     In July 1997 the Company's stockholders recapitalized the Company by
creating a second class of (nonvoting) capital stock to facilitate business
succession plans. The stockholders exchanged 1,248 shares of $1 par value voting
common stock for 2,496 of voting common stock and 59,904 shares of nonvoting
common stock.

12. CONTINGENCIES:

     The Company is a party to certain claims and suits arising out of the
conduct of its business. While there can be no assurance as to their ultimate
outcome, management does not believe these matters will have a material adverse
effect on its consolidated financial condition or operating results.

13. SUBSEQUENT EVENT:

     On February 26, 1999, the stockholders of the Company sold all outstanding
shares of stock to the Orius Corporation of West Palm Beach, Florida for cash
and common stock.

     Orius Capital Corp., Arion Sub, Inc. and Irwin Telecom Holdings, Inc. are
incorporated under the laws of the State of Delaware. Section 145 of the General
Corporation Law of the State of Delaware (the "Delaware Statute") provides that
a Delaware corporation may indemnify any persons who are, or are threatened to
be made, parties to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (a
"proceeding"), other than an action by or in the right of such corporation, by
reason of the fact that such person is or was an officer, director, employee or
agent of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation or
enterprise (an "indemnified capacity"). The indemnity may include expenses,
including attorneys' fees, judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action,
suit or proceeding, provided such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the corporation's best interests
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe that his conduct was illegal. Similar provisions apply to actions
brought by or in the right of the corporation, except that no indemnification
shall be made without judicial approval if the officer or director is adjudged
to be liable to the corporation. Where an officer or director is successful on
the merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses which such officer or
director has actually and reasonably incurred. Section 145 of the Delaware
Statute further authorizes a corporation to purchase and maintain insurance on
behalf of any indemnified person against any liability asserted against him and

capacity, shall be indemnified and held harmless by the corporation to the
fullest extent that it is empowered to do so unless prohibited from doing so by
the Delaware Statute against all expense, liability and loss (including
reasonable attorney's fees); provided, however, that the corporation shall
indemnify any such person seeking indemnification in connection with a
proceeding initiated by such person only if such proceeding was authorized by
the board of directors of the corporation. The right to indemnification
conferred by each of these corporation's bylaws is a contract right and includes
the right to be paid by the corporation the expenses incurred defending any such
proceeding in advance of its final disposition. The corporation may, by action
of its board of directors, provide indemnification to employees and agents of
the corporation with the same scope and effect as the indemnification of its
directors and officers.

     The bylaws of these corporations further provide that the rights to
indemnification and to the advancement of expenses conferred in the bylaws are
not exclusive of any other right which any person has

held harmless by the corporation to the fullest extent permitted by applicable
law, including attorney's fees; provided, however, that the corporation shall
indemnify any such person seeking indemnification in connection with a
proceeding initiated by such person only if such proceeding was authorized by
the board of directors of the corporation.

     The bylaws of Irwin Telecom Holdings, Inc. further provide that the rights
to indemnification conferred in the bylaws are not exclusive of any other right

REGISTRANTS INCORPORATED UNDER IDAHO LAW

     DAS-CO of Idaho, Inc. is incorporated under the laws of the state of Idaho.

Statute") provide, among other things, that an Idaho corporation may indemnify
any person who was or is a party to a proceeding, by reason of the fact he is or

faith and reasonably believed that his conduct was in the best interests of, or
not opposed to the best interests of, the corporation, or, with respect to any
criminal proceeding, he had no reasonable cause to believe his conduct was
unlawful. Notwithstanding the foregoing, the Idaho Statute prevents a
corporation from indemnifying a director in a proceeding brought by or in the
right of a corporation that results in a settlement or judgment against the
director (other than reasonable expenses incurred in connection with the
proceeding), or a proceeding in which the director received an improper
financial benefit as a result of his conduct. Section 856 of the Idaho Statute
prevents a corporation from indemnifying an officer for conduct that constitutes
either an intentional infliction of harm on the corporation or shareholders, or
an intentional violation of criminal law. Where a director or officer is
successful on the merits or otherwise in the defense of any proceeding referred
to above, the corporation must indemnify him against reasonable expenses
incurred by him in connection with the proceeding. A director or officer who is
a party to a proceeding may also apply for indemnification to the court
conducting the proceeding or to another court of competent jurisdiction. The
court may order indemnification if it determines that indemnification is either
required by the Idaho Statute or fair and reasonable under the relevant
circumstances.

     The Idaho Statute also authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was serving in an indemnified
capacity against any liability asserted against or incurred by him in that
capacity or arising from his status as a director or officer, whether or not the
corporation would have the power to indemnify him under the Idaho Statute.

     DAS-CO's articles of incorporation provide that, to the furthest extent
permitted by the corporation's bylaws and Idaho law, the corporation is
authorized to indemnify any of its officers, directors, employees and agents.

merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses which such officer or
director has actually and reasonably incurred.

REGISTRANTS INCORPORATED UNDER PENNSYLVANIA LAW

     Cablemasters, Corp. is incorporated under the laws of the state of
Pennsylvania. The Pennsylvania Business Corporation Law provides that a
Pennsylvania corporation may, under specified circumstances, indemnify their
directors, officers, employees and agents in connection with actions, suits or
proceedings brought against them by third parties and in connection with actions
or suits by or in the right of the corporation, by reason of the fact that they
were or are directors, officers, employees and agents, against expenses,
including attorney's fees, and, in the case of proceedings brought by third
parties, against judgments, fines and amounts paid in settlement actually and
reasonably incurred in any proceeding.

     Cablemasters' bylaws provide that it shall indemnify its directors and
officers and any other person designated as an indemnified representative by its
board of directors against any damage, judgment, amount paid in settlement,
fine, penalty, punitive damages, excise tax assessed with respect to an employee
benefit plan, or cost or expense, of any nature, including, without limitation,
attorneys' fees and disbursements, incurred in connection with any proceeding in
which an individual may be involved as a party or otherwise by reason of the
fact that such person is or was serving in an indemnified capacity,

                                      II-8

including, without limitation, liabilities resulting from any actual or alleged
breach or neglect of duty, error, misstatement or misleading statement,
negligence, gross negligence or act giving rise to strict or products liability,
except:

          (1) where such indemnification is expressly prohibited by applicable
     law;

          (2) where the conduct of the indemnified representative has been
     finally determined:

             (i) to constitute willful misconduct or recklessness under the
        Pennsylvania Statute or any superseding provision of law sufficient in
        the circumstances to bar indemnification against liabilities arising
        from the conduct; or

             (ii) to be used upon or attributable to the receipt by the
        indemnified representative from the corporation of a personal benefit to
        which the indemnified representative is not legally entitled; or

          (3) to the extent such indemnification has been finally determined in
     a final adjudication to be otherwise unlawful.

     Cablemasters' bylaws further provide that it shall not indemnify any person
for any liability incurred in a proceeding initiated or participated in as an
intervenor or amicus curiae by the person seeking indemnification unless the
initiation of or participation in the proceeding was authorized, either before
or after its commencement, by the affirmative vote of a majority of the
directors in office.

REGISTRANTS ORGANIZED UNDER TEXAS LAW

     Network Cabling Services, Inc. is incorporated under the laws of the state
of Texas and Irwin Telecom Services, L.P. and Network Comprehensive Telecom,
L.P. are limited partnerships organized under the laws of the state of Texas.
Article 2.02-1 of the Texas Business Corporation Act and Section 11.02 of the
Texas Revised Limited Partnership Act (the "Texas L.P. Act" and together with
the Texas Business Corporation Act, the "Texas Statutes") authorize a Texas
corporation or limited partnership to indemnify a person who was, is, or is
threatened to be made a named defendant or respondent in a proceeding because
the person is or was a director or a general partner, as the case may be. The
Texas Statutes provide that, unless a court of competent jurisdiction determines
otherwise, indemnification is permitted only the indemnified person conducted
himself in good faith and reasonably believed that, in the case of conduct in
his official capacity as a director of the corporation or a general partner of a
limited partnership, that his conduct was in the corporation's or limited
partnership's best interests, and, in all other cases, that his conduct was at
least not opposed to the corporation's or limited partnership's best interests,
or, in the case of any criminal proceeding, had no reasonable cause to believe
his conduct was unlawful. A person may be indemnified under the Texas Statutes
against judgments, penalties (including excise and similar taxes), fines,
settlements, and reasonable expenses actually incurred by the person (including
court costs and attorneys' fees), but if the person is found liable to the
corporation or limited partnership, or is found liable on the basis that
personal benefit was improperly received by him, the indemnification is limited
to reasonable expenses actually incurred and shall not be made in respect of any
proceeding in which the person has been found liable for willful or intentional
misconduct in the performance of his duty to the corporation or limited
partnership.

     A corporation or limited partnership is obligated under the Texas Statutes
to indemnify a director or officer, in the case of a corporation, or a general
partner, in the case of a limited partnership, against reasonable expenses
incurred by him in connection with a proceeding in which he is named defendant
or respondent because he is or was director or officer or general partner, as
the case may be, if he has been wholly successful, on the merits or otherwise,
in the defense of the proceeding. Under the Texas Statutes, a corporation or
limited partnership may, to the extent consistent with law, provided further
indemnification in it's articles of incorporation, bylaws, by action of its
board of directors, limited partnership agreement, contract or as permitted by
common law and may purchase and maintain insurance or another arrangement on
behalf of person serving in an indemnified capacity against any liability
asserted against such person.
                                      II-9
<PAGE>   271

     The articles of incorporation and bylaws of Network Cabling Services do not
contain provisions governing indemnification.

     Irwin Telecom Services, L.P.'s and Network Comprehensive Telecom, L.P.'s
agreements of limited partnership provide that the general partner, its
officers, directors, employees and owners shall not be liable, responsible or
accountable in damages to any partner, or the partnership, for any act or
omission on behalf of the partnership performed or omitted by them in good faith
and in a manner reasonably believed by them to be within the scope of the
authority granted to the general partner by the agreement of limited partnership
and in the best interests of the partnership, unless they have been guilty of
gross negligence or willful misconduct. To the full extent permitted by the
Texas L.P. Act, the partnership shall indemnify the general partner, its
officers, directors and members, for, and hold the general partner, its officer,
directors and members, harmless from, any loss or damage incurred by them by
reason of any act or omission so performed or omitted by them (and not involving
gross negligence or willful misconduct). To the full extent authorized or
permitted by the Texas L.P. Act, the partnership shall pay or reimburse
reasonable expenses (including reasonable attorneys' fees) incurred by the
general partner, its officers, directors and members, who are a party to a
proceeding in advance of final disposition of such proceeding. The partnership
may purchase and maintain insurance on behalf of the general partner, its
officers, directors, employees and owners against any liability asserted against
or incurred by them as a result of being the general partner, its officers,
directors or members of the general partner, whether or not the partnership
would have the power to indemnify such person against the same liability under
the limited partnership agreement or the Texas L.P. Act.

REGISTRANTS INCORPORATED UNDER VIRGINIA LAW

     Texel Corporation is incorporated under the laws of the state of Virginia.
The Virginia Stock Corporation Act (the "Virginia Statute") permits a
corporation to indemnify any persons who are, or are threatened to be made,
parties to any threatened, pending or completed proceeding by reason of the fact
that such person is or was serving in an indemnified capacity. The indemnity may
include expenses, including attorneys' fees, incurred by such person in
connection with such proceeding, provided such person acted in good faith and in
a manner he reasonably believed to be in or not opposed to the corporation's
best interests and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that his conduct was illegal. A Virginia corporation
may not indemnify a director who, in the case of proceeding brought by the
corporation, is adjudged to be liable to the corporation, or, in the case of
proceeding alleging improper personal benefit, is found to have improperly
received a personal benefit. Indemnification in connection with a proceeding
brought by or in the right of a corporation is limited to reasonable expenses
incurred in connection with the proceeding. Where an officer or director is
successful on the merits or otherwise in the defense of any action referred to
above, the corporation must indemnify him against the expenses which such
officer or director has actually and reasonably incurred.

     The Virginia Statute also permits such persons to seek indemnification
under any applicable bylaw, agreement, vote of stockholders or disinterested
directors or otherwise. The Virginia Statute also permits a corporation to
provide further indemnity, in addition to that otherwise contemplated by the
Virginia Statute, if provided for in the articles of incorporation or a bylaw or
agreement authorized by a stockholder vote, provided that no such
indemnification can be made for willful misconduct or a knowing violation of
criminal law. The Virginia Statute also permits corporations to maintain
insurance for officers and directors against liabilities incurred while acting
in such capacities, whether or not the corporation would be empowered to
indemnify such persons under the Virginia Statute.

     Texel Corporation's articles of incorporation and bylaws do not contain
provisions regarding indemnification.

REGISTRANTS ORGANIZED UNDER WISCONSIN LAW

     U.S. Cable, Inc. is incorporated under the laws of the state of Wisconsin
and Fenix Telecom Services Limited Partnership is a limited partnership
organized under the laws of the state of Wisconsin.

                                      II-10
<PAGE>   272

Sections 180.0850 to 180.0859 of the Wisconsin Corporate Statutes (the
"Wisconsin Statute") require a corporation to indemnify any director or officer
who is a party to any threatened, pending or completed proceeding, to the extent
the director or officer has been successful on the merits or otherwise in the
defense of the proceeding, for all reasonable expenses incurred in the
proceeding if the director or officer was a party because he or she is a
director or officer of the corporation. If the director or officer is not
successful in defense of the proceeding, a corporation must indemnify the
director or officer unless the liability was incurred as a result of the breach
or failure to perform a duty which the director or officer owes to the
corporation and the breach or failure to perform constitutes: (1) a willful
failure to deal fairly with the corporation or its shareholders in connection
with a matter in which the director or officer has a material conflict of
interest; (2) a violation of criminal law, unless the person has reasonable
cause to believe his conduct was lawful or had no reasonable cause to believe
his conduct was unlawful; (3) a transaction from which the person derived an
improper personal profit; or (4) willful misconduct. A corporation's articles of
incorporation may limit its obligation to indemnify under these provisions,
although U.S. Cable's articles do not contain such a limitation. The Wisconsin
Statute also provides that a corporation may purchase and maintain insurance for
officers and directors against liabilities incurred while acting in such
capacities whether or not the corporation would be empowered to indemnify such
persons under the Wisconsin Statute. U.S. Cable's bylaws provide for
indemnification of its officers in accordance with the terms of the Wisconsin
Statute.

     The agreement of limited partnership of Fenix Telecom Services Limited
Partnership provides that, to the fullest extent permitted by the Wisconsin
Revised Uniform Limited Partnership Act, the partnership will indemnify the
general partner, its officers, directors and members for any loss or damage
incurred by them by reason of any act or omission, provided that the act or
omission does not involve gross negligence or willful misconduct. The agreement
of limited partnership also provides that the partnership may purchase insurance
on behalf of the general partner, its officers, directors and members against
any liability asserted against such persons, regardless of whether the
partnership would have the power to indemnify such persons.

REGISTRANTS INCORPORATED UNDER MINNESOTA LAW

     Midwest Splicing & Activation, Inc. is incorporated under the laws of the
state of Minnesota. Midwest's articles of incorporation provide that directors
shall not be liable to the corporation or its shareholders for monetary damages
for breach of fiduciary duty as a director, except for liability for actions
specifically stated in Section 302A.251, Subd. 4(a) through (e) of the Minnesota
Business Corporation Act. This provision provides that a director's personal
liability to the corporation or its shareholders for monetary damages for breach
of fiduciary duty as a director may be eliminated or limited in a corporation's
articles, other than for (1) breaches of the duty of loyalty, (2) acts or
omissions not in good faith or involving intentional misconduct or knowing
violation of law, (3) illegal distributions, (4) transactions for which the
director derived improper personal benefit, and (5) for acts or omissions
occurring prior to the effective date of the articles.

     Midwest's bylaws provide that it shall indemnify to the fullest extent
permitted by law each present or former director or officer or other person
serving in an indemnified capacity, and his legal representatives, against
liabilities, expenses, counsel fees and costs reasonably incurred by him or his
estate in connection with, or arising out of, any proceeding in which he is made
a party by reason of his serving in an indemnified capacity; provided that such
person acted in good faith and in a manner reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to a criminal
action, had no reason to believe her conduct was unlawful. Midwest's bylaws
provide that the right to indemnification under the bylaws is not exclusive of
any other rights to which its directors or officers may be lawfully entitled and
that the corporation may purchase insurance, but only for acts for which
indemnification would be available under the bylaws.

     (a)The undersigned hereby undertakes to file, during any period in which
offers or sales are being made, a post-effective amendment to this registration
statement:

          (1)To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

          (2)To reflect in the prospectus any facts or events arising after the
     effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     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
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective registration statement;

                                      II-14
<PAGE>   276

          (3) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement;

     (b) The undersigned registrant hereby undertakes that, for the purpose of
determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offerings of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c) The undersigned registrant hereby undertakes to remove from
registration by means of a post-effective amendment any of the securities being
registered which remain unsold at the termination of the offering.

     (d) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 20, 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 directors, 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.

     (e) The undersigned 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 date of the registration statement through the date of
responding to the request.

     (f) 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 the registration statement when it became effective.
