                               PROSPECTUS SUMMARY

     This summary contains basic 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
                                 pursuant to 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 and to complete this
                                 exchange offer within 120 days of issuing the
                                 outstanding notes. The exchange offer is
                                 intended to satisfy your rights under the
                                 registration rights agreement. After the
                                 exchange offer is complete, you will 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;

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

                                 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.

                                 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

                                 outstanding notes to the exchange agent or
                                 comply with the procedures for guaranteed

                                 us. Send these documents only to the exchange
                                 agent. See "The Exchange Offer -- Exchange
                                 Agent" for more information.

                                 taxable event for United States federal income
                                 tax purposes. See "United States Federal Income

                     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 December 31, 1999, on a pro
                             forma basis giving effect to the offering of the
                             outstanding notes, the issuers would have had
                             approximately $251.4 million of senior debt, in
                             addition to approximately $88.6 million that they
                             would have 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 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
                             December 31, 1999, on a pro forma basis giving
                             effect to the offering of the outstanding notes,
                             the guarantors would have had approximately $251.4
                             million of senior debt to which their guarantees of
                             the outstanding notes would have been 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."

<PAGE>   9

                             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;

                             - 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 such
                             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.

                             These covenants are subject to a number of
                             important limitations and exceptions.

prospectus for 1998 and 1999 give effect to (1) our acquisition of LISN
Holdings, Inc. and its subsidiaries in December 1999, (2) the 16 other
acquisitions we have completed since March 1998 and (3) the original issuance of
the outstanding notes and the application of the proceeds from that issuance, as
if each of these transactions had occurred at the beginning of the period
presented.

     We are one of the largest independent providers of comprehensive telecom
infrastructure services in the U.S., with operations in 48 states over the past
twelve months. 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."

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, Bell Atlantic, DTI, GTE, MCI
WorldCom, Pacific Bell, Southwestern Bell, U.S. West 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, Comcast, Cox
Communications, MediaCom, MediaOne and Time Warner. In addition, we provide our
Network Services for commercial, governmental and institutional customers such
as Compaq, Dell, EDS, the FDIC 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. 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.

     - Broad Geographic Coverage. Consolidation in the telecom industry has
       created geographically diverse telecom services providers who require
       telecom infrastructure services providers like us with similarly broad
       geographical capabilities.

     - Strong Customer Relationships. More than 80% of our 1999 pro forma
       revenue was derived from repeat 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.

                                        6
<PAGE>   11

     - 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.

     - 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. 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.

     - 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.

                               BUSINESS STRATEGY

     Our objective is to enhance 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:

     - 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 three 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

                                        7
<PAGE>   12

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. The aggregate purchase
price for these acquisitions was approximately $44.5 million, consisting of
approximately $35.5 million of cash, $7.7 million of Parent's securities and the
assumption of $1.3 million of debt. We funded $15.5 million of the cash purchase
price with borrowings under our senior credit facilities. These three companies
had aggregate revenue and EBITDA for the year ended December 31, 1999 of $43.6
million and $10.6 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.

                                EQUITY INVESTOR

     Willis Stein & Partners is a leading private equity investment firm based
in Chicago, Illinois that specializes in negotiated investments in the telecom,
business services, media and publishing, manufacturing, financial services and
health care industries. Willis Stein & Partners, through its limited partnership
funds, had approximately $1.2 billion of assets under management as of December
31, 1999. Other investments sponsored by Willis Stein & Partners in the telecom
and media sectors include The Petersen Companies, Protocol Holdings, College
Television Network, Interlink Communication Partners and LISN Holdings, Inc.
Unless otherwise noted, references in this offering memorandum to Willis Stein &
Partners refer to Willis Stein & Partners II, L.P., Willis Stein & Partners
Dutch, L.P. and their respective management companies.

                                  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

THERE IS NO PUBLIC MARKET FOR THE NOTES--YOU MAY NOT BE ABLE TO SELL 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, and
there can be no assurance as to:

     - the liquidity of any trading market that may develop;

     - the ability of holders to sell their exchange notes; or

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

     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 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. There can be no assurance that an active trading market
will exist for the notes or that any trading market that does develop will be
liquid.

     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.

YOUR OUTSTANDING NOTES WILL NOT BE ACCEPTED FOR EXCHANGE IF YOU FAIL TO FOLLOW
THE EXCHANGE OFFER PROCEDURES

     We will issue exchange notes pursuant to 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. We are under no duty to give notification of defects or irregularities
with respect to the tenders of outstanding 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 BE
UNABLE 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 be unable to sell
your outstanding notes.

                                       10
<PAGE>   15

RISKS RELATING TO THE NOTES

WE HAVE SUBSTANTIAL DEBT, SO WE MAY NOT BE ABLE TO MAKE PAYMENTS ON THE NOTES

     We have indebtedness that is substantial in relation to our stockholders'
equity. As of December 31, 1999, on a pro forma basis giving effect to the
offering of the outstanding notes, we would have had $542.5 million in aggregate
principal amount of consolidated indebtedness outstanding, $251.4 million of
which would have been senior to the notes, and a stockholders' deficit of $186.1
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 with
respect to 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. If our cash flow and
capital resources are insufficient to fund our debt service obligations, we may
be forced to reduce or delay scheduled expansion and capital expenditures, sell
material assets or operations, obtain additional capital or restructure our
debt. We cannot assure you that our operating performance, cash flow and capital
resources will be sufficient for payment of our debt in the future. 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 cannot assure you as
to the terms of any such transaction or how soon any such transaction could be
completed. 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 RISKS DESCRIBED ABOVE

     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 December 31, 1999, on a pro
forma basis, we would have been able to incur an additional $88.6 million of
borrowings under our revolving 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.

THE NOTES AND THE GUARANTEES ARE SUBORDINATED TO SENIOR DEBT

     Payment on the notes is subordinated in right of payment to all of our
senior indebtedness, including the senior credit facilities. As of December 31,
1999, on a pro forma basis, the aggregate principal amount

                                       11
<PAGE>   16

of our consolidated indebtedness to which the notes would have been subordinated
was approximately $251.4 million. 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 such a
proceeding, 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 certain non-payment defaults on our senior debt. The notes are
unsecured, and are effectively subordinated to all secured obligations to the
extent of the value of the assets securing such obligations. The guarantees are
similarly subordinated and, as of December 31, 1999, on a pro forma basis, would
have been subordinated to approximately $251.4 million of debt.

YOU SHOULD NOT RELY ON ORIUS CAPITAL OR ON PARENT'S GUARANTEE IN EVALUATING AN
INVESTMENT IN THE NOTES

     Orius Capital was formed in connection with the initial offering of the
outstanding notes and has no assets and no operations 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 CONDUCTS ALL OF ITS OPERATIONS THROUGH 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'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.

THE NOTES ARE UNSECURED -- YOUR RIGHT TO ENFORCE REMEDIES IS LIMITED BY THE
RIGHTS OF HOLDERS OF SECURED DEBT

     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 becomes insolvent or is liquidated, or if payment under the senior
credit facilities is accelerated, the lenders under the senior credit facilities
will be entitled to exercise the remedies available to a secured lender under
applicable law. These lenders will have a claim on all assets securing the
senior credit facilities before the holders of unsecured debt, including the
notes.

OUR SENIOR CREDIT FACILITIES AND THE INDENTURE GOVERNING THE NOTES RESTRICT OUR
OPERATIONS

     Our senior credit facilities contain numerous restrictive covenants,
including, among other things, covenants that limit our ability to borrow money,
make capital expenditures, use assets as security in other transactions, make
restricted payments or restricted investments, incur contingent obligations,
sell assets and enter into leases and transactions with affiliates. In addition,
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.

                                       12
<PAGE>   17

     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. 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, in such case, the
maturity of substantially all of our long-term indebtedness could be
accelerated.

     The indenture also imposes operating and financial restrictions on us that
limit our ability to:

     - borrow money;

     - make dividends and other restricted payments;

     - use assets as security in other transactions;

     - enter into transactions with affiliates;

     - pay dividends on or purchase our stock or our significant restricted
       subsidiaries' stock;

     - enter into new businesses;

     - issue and sell stock of restricted subsidiaries; and

     - sell assets or merge with or into other companies.

     A default under the indenture would also constitute an event of default
under our senior credit facilities and the lenders under the senior credit
facilities could elect to declare all amounts borrowed under the senior credit
facilities, together with accrued interest, to be due and payable. If we were
unable to repay these borrowings, the lenders could proceed against our assets,
which secure our borrowings under the senior credit facilities. If the
indebtedness under the senior credit facilities was accelerated, we cannot
assure you that we would be able to repay the indebtedness under the senior
credit facilities and the notes in full. See "Description of Senior Credit
Facilities" and "Description of the Notes."

THE GUARANTEES MAY BE UNENFORCEABLE DUE TO FRAUDULENT CONVEYANCE STATUTES

     The obligations of the guarantors may be subject to challenge under state
or federal fraudulent transfer laws. 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 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.

If a guarantee were determined to be a fraudulent conveyance, it could be
unenforceable.

WE MAY NOT BE ABLE TO REPURCHASE THE NOTES UPON A CHANGE OF CONTROL OFFER

     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 any such
purchase, in which event we would be in default on the notes. See "Description
of the Notes -- Change of Control."

RISKS RELATING TO OUR BUSINESS

OUR HISTORICAL AND PROPOSED GROWTH BY ACQUISITION MAY ADVERSELY AFFECT OUR
OPERATING RESULTS

     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;

     - the potential disruption of our business; and

     - customer dissatisfaction or performance problems at the acquired
       businesses.

     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. In addition, we expect to face
competition for acquisition candidates, which may limit the number of our
acquisition opportunities and may lead to higher acquisition prices. The
realization of all or any of the risks described above could materially and
adversely affect the reputation of our company and our results of operations.

WE MAY NOT BE ABLE TO CONTINUE OUR GROWTH THROUGH ACQUISITIONS

     We may be unable to support our strategy of growth through acquisitions if
we cannot finance future acquisitions. 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. If we seek to issue more debt, we may
have to agree to financial covenants that limit our operational and financial
flexibility. When we seek additional debt or equity financings, we cannot be
certain that we will be able to complete such financings or that we will be able
to complete such financings 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. We cannot readily predict
the timing, size and success of our acquisition efforts or the capital we will
need for these efforts.

WE MAY ENCOUNTER DIFFICULTIES IN MANAGING OUR GROWTH

     Our recent growth has placed, and is expected to continue to place, a
significant strain on our managerial, operational and financial resources. To
manage any future growth, we must continue to implement and improve our
operational and financial systems, and must expand, train and manage our

                                       14
<PAGE>   19

expanded employee base. We cannot assure you that we will not encounter
unexpected difficulties in managing the expansion of our operations, or that our
systems, products and controls will be adequate to support our expanded
operations. Any inability to manage growth effectively could have a material
adverse effect on our business, results of operations and financial condition.

ALL OF OUR CUSTOMER CONTRACTS CAN BE CANCELED ON SHORT NOTICE

     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,
we cannot assure you that our future revenues will approximate our historical
performance. In addition, because all of our customer contracts are cancelable,
our backlog, which was approximately $559.3 million as of March 31, 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, we could be
unable to meet our fixed expenses and our profitability could be materially and
adversely affected.

WE ARE DEPENDENT ON BELL ATLANTIC AS OUR LARGEST CUSTOMER

     Our revenue from Bell Atlantic represented approximately 21% of our pro
forma revenue for 1999. In recent months, our revenue from Bell Atlantic 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 Bell Atlantic as a
customer or a significant decline in its demand for our services could have a
material adverse effect on us. Many of our contracts with Bell Atlantic 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.

WE HAVE EXPERIENCED AND EXPECT TO CONTINUE TO EXPERIENCE QUARTERLY VARIATIONS IN
REVENUES AND NET INCOME

     Our revenue and net income in the first quarter and the fourth quarter have
in the past been, and may in the future be, materially and negatively affected
by adverse holiday season shutdowns, weather conditions and the year-end
budgetary spending patterns of our customers.

     Quarterly variations in our revenues and net income result from many
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;

     - fluctuations in construction and design costs; and

     - regional and general economic conditions.

WE ARE VULNERABLE TO FLUCTUATIONS IN INTEREST RATES

     A substantial portion of our existing indebtedness, including all of our
indebtedness under our senior credit facilities, bears interest at variable
rates. 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 have a material adverse effect on our business, results of
operations and financial condition.

                                       15

OUR MASTER SERVICE, TURNKEY AND OTHER MAINTENANCE SERVICE AGREEMENTS SUBJECT US
TO UNCERTAIN REVENUE GROWTH AND SUBSTANTIAL UNREIMBURSED EXPENDITURES

     A significant decline in work assigned to us under our master service,
turnkey and other maintenance service agreements could materially and adversely
affect our results of operations due to a decline in revenue and our inability
to offset expenditures for working capital and equipment. 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. 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. Under our turnkey agreements, the substantial working
capital and equipment required during the initial stages of these agreements and
the fixed unit-priced nature of these agreements subject us to additional risks.

WE MAY BE UNABLE TO ATTRACT AND RETAIN QUALIFIED EMPLOYEES

     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. Accordingly, our ability to increase our productivity and
profitability will be limited by our ability to attract, train and retain
skilled personnel. We, like many of our competitors, are currently experiencing
shortages of qualified personnel. We cannot be certain that we will be able to
maintain an adequate skilled labor force necessary to operate efficiently and to
support our growth strategy or that our labor expenses will not 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.

TECHNOLOGICAL AND REGULATORY CHANGES COULD REDUCE DEMAND FOR OUR SERVICES

     New technologies could reduce the need for installation, repair and
replacement of wireline services, which could reduce the demand for our
services. 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. 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.

WE MAY BE UNABLE TO SUCCESSFULLY COMPETE WITH OTHER COMPANIES IN THE INDUSTRY

     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.

     Competition in the industry depends on a number of factors, including
price. Our competitors may have lower overhead cost structures and may,
therefore, be able to provide their services at lower rates than we can. Our
competitors may have greater market presence, engineering and marketing
capabilities, and financial, technological and personnel resources than those
available to us. 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

                                       16
<PAGE>   21

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 business
would be negatively impacted if these customers increased the amount of services
performed by their in-house organizations. Accordingly, we cannot assure you
that we will be able to maintain or enhance our competitive position.

THE INTERESTS OF OUR CONTROLLING STOCKHOLDERS COULD CONFLICT WITH THOSE OF THE
HOLDERS OF THE NOTES

     Willis Stein & Partners will own capital stock representing approximately
42% of the outstanding voting power of Parent after we exercise our rights under
the call options with Parent's stockholders. 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. The directors have the
authority to make decisions affecting Parent's capital structure, including the
issuance of additional indebtedness and the declaration of dividends. We cannot
assure you that the interests of Willis Stein & Partners do not and will not
conflict with the interests of the holders of the Notes.

THE DEPARTURE OF KEY PERSONNEL COULD DISRUPT OUR BUSINESS

     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. The loss of the
services of any of our key employees could have a material adverse effect on our
business by disrupting our business plan and growth strategy.

WE COULD BE ADVERSELY AFFECTED BY ENVIRONMENTAL AND SAFETY REQUIREMENTS

     We are subject to the requirements of federal, state and local
environmental and occupational health and safety laws and regulations. These
requirements are complex, constantly changing and have tended to become more
stringent over time. It is possible that these requirements may change or
liabilities may arise in the future in a manner that could have a material
effect on our business. We cannot assure you that we have been or will be at all
times in complete compliance with all such requirements or that we will not
incur material costs or liabilities in connection with such requirements in the
future.

THE HISTORICAL FINANCIAL STATEMENTS INCLUDED IN THIS OFFERING MEMORANDUM ARE OF
LIMITED VALUE IN EVALUATING OUR HISTORICAL PERFORMANCE OR IN DETERMINING WHETHER
TO INVEST IN THE NOTES

     We had no substantive operations prior to March 1998. Since March 1998, we
have acquired 17 companies, including the acquisition of LISN in December 1999.
The deemed acquisition of Parent by LISN and all of our other acquisitions were
accounted for using the purchase method of accounting. As a result, the
historical financial statements of NATG's predecessor or LISN, as the case may
be, 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, the historical financial statements of LISN
and NATG's predecessor 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 thereto, included in this offering memorandum,
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
variations thereon 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 such forward-looking statements
are reasonable, we can give no assurance that such 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 offering memorandum, 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.

MARKET, RANKING AND OTHER DATA IS SUBJECT TO CHANGE AND CANNOT BE VERIFIED WITH
                               COMPLETE CERTAINTY

     The market, ranking and other data contained in this offering memorandum
are based either on independent industry publications, reports by market
research firms or other published independent sources, or on management's own
estimates and, in each case, are believed by management to be reasonable
estimates. However, market data is subject to change and cannot always be
verified with complete certainty due to limits on the availability and
reliability of raw data, the voluntary nature of the data gathering process and
other limitations and uncertainties inherent in any statistical survey of market
size. In addition, consumption patterns and consumer preferences can and do
change. As a result, you should be aware that market, ranking and other similar
data set forth in this offering memorandum, and estimates and beliefs based on
such data, may not be reliable.

                                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 either redeemed, or entered into put
       and call arrangements pursuant to which we will redeem during the second
       and third quarters of 2000, 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. Our obligations in respect of these put and call agreements
       are supported by letters of credit issued under the senior credit
       facilities. A total of $46.5 million of letters of credit were issued
       under the tranche A term loan letter of credit subfacility to fund the
       amounts payable upon exercise of our call options. As of March 31, 2000,
       $40.8 million had been drawn under these letters of credit to fund
       amounts payable upon the exercise of a portion of the call options.
       Additional amounts will be drawn during the second and third quarters of
       2000 to fund the remaining amounts payable upon exercise of the remaining
       call options. Additional standby letters of credit in an aggregate amount
       of $9.3 million were issued under the revolving credit facility but will
       expire in accordance with their terms without being drawn when we
       exercise our call options. As of March 31, 2000, $2.1 million of these
       standby letters of credit had expired.

     - 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, such 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. In addition, unless otherwise indicated, we have assumed throughout
this prospectus that we have exercised all of the call options described above.
We entered into the put and call arrangements described above as an
accommodation to certain of Parent's former stockholders for their personal tax
planning.

     Following the exercise of the call options, the investor group led by
Willis Stein & Partners will own capital stock representing approximately 67% of
Parent's voting power and the management of Parent and

                                       19
<PAGE>   24

its subsidiaries, including LISN, will own capital stock representing
approximately 33% of Parent's voting power.

     The LISN acquisition resulted in each stockholder of Parent, except to the
extent such stockholders' shares are subject to put and call agreements, 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 such 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, at our expense,
for the benefit of the holders of the notes:

     (1) within 120 days after the date on which the outstanding notes were
issued, file a registration statement on an appropriate registration form (the
"exchange offer registration statement") with respect to a registered exchange
offer to exchange the notes for exchange notes, which exchange notes will have
terms substantially identical in all material respects to the notes except that
the exchange notes will not contain terms with respect to transfer restrictions;

     (2) 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;

     (3) keep the exchange offer open for not less than 30 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 notes surrendered pursuant to the exchange offer, the
holder who surrendered such note will receive an exchange note having a
principal amount equal to that of the surrendered note. Interest on each
exchange note will accrue (A) from the later of (i) the last interest payment
date on which interest was paid on the outstanding note surrendered in exchange
for the exchange note, or (ii) if the note is surrendered for exchange on a date
in a period which includes the record date for an interest payment date to occur
on or after the date of such exchange and as to which interest will be paid, the
date of that interest payment date or (B) if no interest has been paid on the
outstanding note, from the date on which the outstanding notes were issued.

     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
represent:

     (1) that any exchange notes to be received by it will be acquired in the
ordinary course of its business,

     (2) that at the time of the commencement of the exchange offer it 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,

     (3) that it is not our affiliate as defined in Rule 405 promulgated under
Securities Act,

     (4) if such holder is not a broker-dealer, that it is not engaged in, and
does not intend to engage in, the distribution of exchange notes,

     (5) if such holder is a broker-dealer (a "participating 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, that it will deliver a prospectus in connection with any resale of
such exchange notes, and

     (6) such holder is not acting on behalf of any person or entity that could
not truthfully make the foregoing 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 other persons, if any, with similar
prospectus delivery requirements for use in connection with any resale of
exchange 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,

                                       22
<PAGE>   27

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

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

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

     then in each case, we will promptly deliver to the holders and the trustee
and at our sole expense, as promptly as practicable: (A) file a shelf
registration statement covering resales of the outstanding notes (the "shelf
registration statement") and (B) use our respective 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 pursuant to 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 shall become payable
in respect of the outstanding notes as follows:

          (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 such
     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 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; or

          (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 such required effectiveness
     date, additional interest shall accrue on the principal amount of the notes
     at a rate of 0.5% per annum for the first 90 days immediately following the
     required effectiveness date, and the additional interest rate will increase
     by an additional 0.5% per annum at the beginning of each subsequent 90-day
     period; or

          (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 shall accrue at a rate of 0.50% per
     annum for the first 90 days commencing on the (x) 31st day after the
     effective date, in the case of (A) above, (y)the day such

                                       23
<PAGE>   28

     shelf registration statement ceases to be effective in the case of (B)
     above or (z) the day such suspension period commences in the case of (C)
     above, and the additional interest rate shall 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
the foregoing clauses (1) through (3) at any one time and at no time shall the
aggregate amount of additional interest accruing exceed in the aggregate 1.5%
per annum. In addition, (A) upon the filing of the exchange offer registration
statement or a shelf registration statement in the case of clause (1) above, (B)
upon the effectiveness of the exchange offer registration statement or a shelf
registration statement in the case of clause (2) above, or (C) or upon (X) the
exchange of the applicable exchange notes for all notes tendered, in the case of
clause (3)(A) above), (Y) the effectiveness of the applicable shelf registration
statement which had ceased to remain effective, in the case of clause (3)(B)
above, or (Z) 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 pursuant to 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 its outstanding notes will not have any further registration
rights and the outstanding notes will continue to be subject to certain
restrictions on transfer. Accordingly, the liquidity of the market for the
outstanding notes could be adversely affected.

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 its
outstanding notes pursuant to 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
         hence will not bear legends restricting the transfer thereof; and

     (3) the holders of the exchange notes will not be entitled to certain
         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             , 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

                                       24
<PAGE>   29

conduct the exchange offer in accordance with the applicable requirements of the
Exchange Act and the rules and regulations of the SEC thereunder.

     We will be deemed to have accepted validly tendered outstanding notes when,
as and if we have given oral or written notice thereof 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 thereof 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 notes pursuant to 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
            , 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.

     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 thereof, 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
thereof 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 thereon to, but not including, the date of issuance of the
exchange notes. Such interest will be paid with the first interest payment on
the exchange notes on August 1, 1999. 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 complete, sign
and date the letter of transmittal, or a facsimile thereof, have the signatures
thereon guaranteed if required by the letter of transmittal or transmit an
agent's message in connection with a book-entry transfer, and 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

                                       25
<PAGE>   30

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: (1) to participate in ATOP; (2) to be bound by the terms of
the letter of transmittal; and (3) 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."

     The tender by a holder and our acceptance thereof 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 OLD 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 tendered pursuant to the letter of transmittal 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 of any outstanding notes listed in this prospectus, 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 thereon 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, and
subject to the establishment thereof, 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

                                       26
<PAGE>   31

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 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, unless otherwise provided in the letter of transmittal, 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

transfer, prior to the expiration date, may effect a tender if:

          (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, stating that the tender is being made thereby and
     guaranteeing that, within three New York Stock Exchange trading days after
     the expiration date, the letter of transmittal or facsimile thereof
     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; and

     facsimile thereof, as well as the certificate(s) representing all tendered

     account at DTC, and all other documents required by the letter of
     transmittal are received by the exchange agent within five New York Stock
     Exchange trading days after the expiration date.

     Upon request to the exchange agent, a Notice of Guaranteed Delivery will be

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.

                                       27
<PAGE>   32

     To withdraw a tender of outstanding notes in the exchange offer, 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 have the trustee with respect to the
     outstanding notes 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, whose 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 thereto unless the outstanding
notes so withdrawn are validly retendered. Any outstanding notes which have been
tendered but which are not accepted for exchange will be returned to the holder
thereof 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 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 will, 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 (see "--Withdrawal of Tenders") or (3) waive the unsatisfied
conditions with respect to the exchange offer and accept all properly tendered
outstanding notes which have not been withdrawn.

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. Such 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 pursuant to
the exchange offer will remain restricted securities. Accordingly, the
outstanding notes may be resold only:

          (1) to us upon redemption thereof or otherwise;

             - so long as the outstanding notes are eligible for resale pursuant
               to 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

                                       29
<PAGE>   34

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

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

          - pursuant to an effective registration statement under the Securities
            Act, in each case in accordance with any applicable securities laws

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, other than a person that is our affiliate within
the meaning of Rule 405 under the Securities Act,in exchange for outstanding
notes in the ordinary course of business and who is not participating, does not
intend to participate, and has no arrangement or understanding with any person
to participate, in the distribution of the exchange notes, 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.
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."

                                 CAPITALIZATION

     The following table sets forth, as of December 31, 1999: (1) Orius' pro
forma consolidated capitalization prior to the offering of the outstanding
notes, and (2) Orius' pro forma consolidated capitalization as adjusted to give
effect to the offering of the outstanding notes. See "Use of Proceeds" and
"Unaudited Pro Forma Financial Statements."

                    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 and Midwest Splicing 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
period presented and what our combined financial position might have been at
December 31, 1999. 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 Orius had acquired each of
the Acquired Companies at the beginning of the period presented and (2)
adjusting such 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,

          (c)the financing transactions associated with those acquisitions and

          (d) the sale of the notes and the application of the net proceeds from
     that sale.

     We prepared the unaudited pro forma balance sheet data by combining the
historical balance sheet data of Orius, Irwin, Fenix and Midwest Splicing as of
December 31, 1999 and adjusting such data to reflect items (a), (c) and (d)
described above with respect to those acquisitions. 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.

(1) Results for the year ended December 31, 1999 represent the combined
    historical results for such periods 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.

    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 the Company. 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 Orius' stock option plan at the time of the LISN acquisition.

(6) Reflects the amortization of goodwill generated due to the LISN acquisition
    based on a goodwill life of 25 years.

                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 and the
acquisitions of Fenix and Midwest Splicing in April 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.

(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 and amortization expense consist
    of the following:

    facility to fund the Fenix acquisition using an assumed interest rate of
    9.08% and interest of $340 on the junior subordinated notes issued in
    connection with the acquisitions of Irwin, Fenix and Midwest using an
    assumed interest rate of 12%.

(5) Reflects the income tax rate that would have been in effect if the Acquired
    Companies had been combined and subject to a federal statutory rate of 35%
    and the applicable state statutory rate for each of the acquired businesses
    throughout the period presented.

                       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 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 such 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. The financial data set forth below has been reclassified to
the classifications used for the pro forma financial data set forth elsewhere in
this prospectus.

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

     The following discussion and analysis contains statements of a
forward-looking nature relating to future events or our future financial
performance. These statements are only predictions and the actual events or
results may differ materially from the results discussed in the forward-looking
statements. Factors that could cause or contribute to these differences include,
but are not limited to, those discussed in "Risk Factors," as well as those
discussed elsewhere in this prospectus. The historical results set forth in this
discussion and analysis are not necessarily indicative of trends with respect to
our actual or projected future financial performance. This discussion and
analysis should be read in conjunction with the financial statements and related
notes which appear elsewhere in this prospectus.

OVERVIEW

     We are one of the largest independent providers of comprehensive telecom
infrastructure services in the U.S., with operations in 48 states over the past
twelve months. 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."

Of our pro forma revenues for the year ended December 31, 1999, approximately
63% was derived from External Telecom Services and 37% was derived from Internal
Telecom Services. Of these revenues, 51% was from services provided to
telecommunications services providers, 38% was from services provided to
broadband services providers and 11% 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

                                       42
<PAGE>   47

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 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.

we acquired LISN. In January 2000, we acquired Irwin and in April 2000, we
acquired Fenix and Midwest Splicing.

     Our 17 completed acquisitions had pro forma 1999 revenues of approximately
$551.9 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
$360.5 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 $14.4 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 three acquisitions. In January
2000, we completed the acquisition of Irwin. 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 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. The aggregate purchase price for these
acquisitions was approximately $44.5 million, consisting of approximately $35.5
million of cash, $7.7 million of Parent's securities and the assumption of $1.3
million of debt. We funded $15.5 million of the cash purchase price with
borrowings under our senior credit facilities. These three companies had
aggregate revenue and EBITDA for the year ended December 31, 1999 of $43.6
million and $10.6 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 such 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. The financial data referred to below has been
reclassified to conform to the classifications used for the pro forma data above
and, as a result, differs from those used in the historical financial statements
of ARION, Inc. and LISN, Inc.

  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

                                       44
<PAGE>   49

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.

                                       45
<PAGE>   50

     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 AND COMBINED RESULTS OF OPERATIONS

     The following table sets forth certain unaudited pro forma financial data
and such data as a percentage of revenue for the periods indicated. Financial
data for the years ended December 31, 1998 and December 31, 1999 give pro forma
effect to those transactions described under the heading "Unaudited Pro Forma
Financial Statements," as if those transactions had occurred at the beginning of
the periods presented. See "Unaudited Pro Forma Financial Statements." For
purposes of the discussion below, we have included unaudited pro forma financial
data because we believe it provides a more meaningful basis for period-to-period
comparisons than the actual historical financial data.

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

     Revenue. Revenue increased 49%, or $181.7 million, from $370.2 million for
the year ended December 31, 1998 to $551.9 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 $74.5 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 Bell Atlantic, 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 50%, or $132.4 million, from $265.7
million for the year ended December 31, 1998 to $398.1 million for the year
ended December 31, 1999. The increase was the result of an increase in our level
of activity. Direct costs increased as a percentage of revenue from 71.8% for
the year ended December 31, 1998 to 72.1% for the year ended December 31, 1999.
This increase is attributable to an increase in subcontracted labor, which is
more expensive than our internal labor force.

     General and Administrative Expenses. General and administrative expenses
increased 30%, or $12.4 million, from $41.7 million for the year ended December
31, 1998 to $54.1 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
1.5% decrease in general and administrative expenses as a percentage of revenue
from 11.3% for the year ended December 31, 1998 to 9.8% for the year ended
December 31, 1999. This decrease resulted from leveraging

                                       46
<PAGE>   51

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 $21.9 million for the year ended December 31, 1998 and $25.1 million
for the year ended December 31, 1999.

     Interest Expense. Interest expense, net, was $62.4 million for the year
ended December 31, 1998 and $62.4 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 $13.8
million, from a benefit of $3.9 million for the year ended December 31, 1998 to
an expense of $9.9 million for the year ended December 31, 1999. Our effective
tax rate rate increased from (19)% for the year ended December 31, 1998 to 82%
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 provide for aggregate borrowings of up
to $375.0 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; and

     - $200.0 million tranche B 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 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.

     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. 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 March 31,
2000, there was $232.7 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), $34.8 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.

     As of March 31, 2000, rates on borrowings under the senior credit
facilities ranged from 8.9% to 9.5%. 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

                                       47
<PAGE>   52

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 and borrowings under the tranche B term
loan are due December 15, 2006. The tranche A and tranche B term loans are
payable quarterly in arrears beginning March 31, 2000.

     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, in any such case, 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 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 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 such 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
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 December 31, 1999, we had $28.7 million of cash and cash equivalents,
working capital of $115.4 million, including $5.5 million of short-term debt,
and long-term debt of $326.4 million, net of current maturities, and no
borrowings under our $100.0 million revolving credit facility.

                                       48
<PAGE>   53

     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.

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 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
March 31, 2000, we had variable rate debt of approximately $232.7 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 $2.1 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 March 31, 2000. These agreements limit, but do
not eliminate, our exposure in the event LIBOR exceeds 7.0%.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     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 second 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 are one of the largest independent providers of comprehensive telecom
infrastructure services in the U.S., with operations in 48 states over the past
twelve months. 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."

     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 year ended December 31, 1999, we had
pro forma revenue of $551.9 million and pro forma EBITDA of $99.6 million.

     Our 1999 pro forma revenue was derived 63% from External Telecom Services
and 37% 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, Pacific Bell, Southwestern Bell,
U.S. West and Williams Communications, and providers of broadband services, such
as Adelphia, AT&T Broadband & Internet Services, Charter Communications,
Comcast, Cox Communications, MediaCom, MediaOne and Time Warner. We also provide
our Network Services for customers such as Compaq, Dell, EDS, the FDIC 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 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 such 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

     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 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

                                       50
<PAGE>   55

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 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

                                       51
<PAGE>   56

       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 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 five largest companies, including us,
       accounting for less than 10% of estimated total industry revenues, and
       includes hundreds of significantly smaller local and regional companies
       that can only offer their services over a limited geographic area. 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 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.

                                       52
<PAGE>   57

     - 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 15 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 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 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 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

                                       53
<PAGE>   58

        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 17 companies since March 1998,
       including our acquisition of LISN, and have gained significant experience
       in identifying, purchasing and integrating telecom infrastructure
       businesses. 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 more of the following criteria: (1) adding additional and/or
       complementary technical capabilities; (2) increasing our range of
       services; (3) increasing our customer base; (4) expanding our geographic
       presence; (5) increasing our penetration of existing markets; and (6)
       creating potential operating synergies. We believe that our national
       presence, financial resources, experienced management and decentralized
       operating strategy will continue to make us attractive to acquisition
       candidates.

     - 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,

                                       54
<PAGE>   59

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 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 17 telecom
infrastructure services providers. These companies had pro forma revenues for
the twelve months ended December 31, 1999 of approximately $551.9 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
acquiror 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.

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.

                                       56

     EXTERNAL TELECOM SERVICES

     Our three primary types of External Telecom Services contracts include:

     - installation contracts for specific projects,

     - master service agreements for all specified services within a defined
       geographic territory, and

     - 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 and $269 million for the year ended December 31, 1999.

     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 and $40 million for the year ended December
31, 1999.

     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 and $38 million for the year ended December 31, 1999.

     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 and
$145 million in 1999.

     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 served a diverse group of more than 200 customers during 1999, 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 51% of our pro forma 1999
       revenue;

     - broadband services providers, such as Media One and Time Warner, which
       accounted for approximately 38% 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 11% of our 1999 pro forma revenue.

</TABLE>

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

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 our 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 March 31, 2000, our pro forma backlog was approximately $559
million. Of that amount, approximately $353 million was for work scheduled to be
performed in 2000

                                       59
<PAGE>   64

and approximately $178 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 December 31, 1999, on a pro forma basis, we had approximately 4,600
employees, approximately 9% of whom were salaried, approximately 78% of whom
were paid on an hourly basis and approximately 13% of whom were paid on a
production basis. Our hourly employees have an average hourly wage of $16 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 January 15,
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
December 31, 1999, on a pro forma basis, we had approximately 1,500
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 is approximately 125,000 square feet and the total
annual base rent for these facilities is approximately $1.1 million. The leases
for these facilities have terms ranging from month-to-month to five years. None
of the individual leases is material

                                       60
<PAGE>   65

to our operations. 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 such 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.

     Each of our facilities is leased, with the exception of the headquarters
for Schatz Underground Cable in Villa Ridge, Missouri, the training, warehouse
and distribution facility for Schatz Underground Cable in Kansas City, Missouri,
the LISN headquarters in Amherst, Ohio and LISN's training and regional office
in Lorain, Ohio. The following is a list of our material facilities.

COMPETITION

     The telecom infrastructure services industry is highly fragmented, with the
five largest companies, including us, accounting for less than 10% of total
estimated industry revenues in 1998. 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.

     E. Scott Kasprowicz, President of our subsidiary Texel Corporation, has
filed suit against us alleging that we breached the stock purchase agreement
pursuant to which we purchased the stock of Texel from Mr. Kasprowicz. Mr.
Kasprowicz alleges that we owe him $3,664,626.75 as a result of a purchase price
adjustment under that agreement. It is our position that no amounts are owed Mr.
Kasprowicz as a result of the purchase price adjustment and we therefore intend
to defend this action.

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 such 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.

(1) Mr. Agres' options became vested and were exercised in connection with the
    LISN acquisition.

(2) At the time of the LISN acquisition, Mr. Vanke held options to purchase
    679.66 shares of LISN common stock. In connection with the LISN acquisition,
    these options were converted into the right to purchase 250,533.2 shares of
    Parent's common stock (as adjusted for our March 2000 10-for-1 stock split)
    and 1,693.12 shares of Parent's series C preferred stock. The calculated
    value of these options is based on the values per share at the time of the
    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 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

                                       66
<PAGE>   71

agreement if Mr. Mercurio resigns without good reason or is terminated with
cause or (2) such time as we cease making any severance payments to him under
the management agreement.

     Under the management agreement, Parent has 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 will purchase these shares by
issuance of a promissory note, which is secured by a pledge of the shares. 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. Mullen. Mr. Mullen has an employment agreement with Parent, as amended
on September 24, 1999, which expires on June 30, 2002. Mr. Mullen's employment
agreement provides that he will receive a base salary of $220,000, which will
increase to $225,000, effective March 24, 2000. Mr. Mullen is also entitled to a
bonus based on the performance of the broadband services segment of our External
Telecom

                                       67
<PAGE>   72

Services business. If Parent terminates Mr. Mullen without cause, it must pay
him his base salary through June 29, 2001. If Parent terminates Mr. Mullen's
employment for cause, he will be entitled to his base salary through the date of
termination. "Cause" includes (1) the commission of a felony or fraud, (2) the
entry of a judgment enjoining him from performing the services required by his
employment agreement, (3) willful misconduct or (4) any other material breach of
his employment agreement. Mr. Mullen has agreed not to compete with the Company
through the later of June 30, 2002 or 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
to 100% of his base salary based on the achievement of certain EBITDA targets by
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.

STOCK OPTIONS

     Mr. Agres held options under Parent's former stock option plan, which was
terminated in connection with the LISN acquisition. Each of his outstanding
options was terminated in exchange for an amount equal to the difference between
(1) the per share price paid to holders of Parent's common stock who received
cash for their shares of common stock in connection with the LISN acquisition,
less (2) the exercise price for the option. In connection with the LISN
acquisition, Mr. Agres received $132,949 in exchange for his options to Parent
common stock.

PARENT EQUITY INCENTIVE PLAN

     In connection with the LISN acquisition, Parent intends to adopt a new
equity incentive plan. We anticipate that the plan will provide for the grant of
shares of Parent's common stock and series C preferred stock or options to
purchase such shares to its and its subsidiaries' employees, directors,
officers, consultants and advisors. Under the plan, Parent shall reserve for
issuance (1) an aggregate number of shares of common stock equal to 5.0% of the
number of shares of Parent's common stock issued and outstanding upon
consummation of the LISN acquisition to those persons identified below and (2)
107,103 shares of common stock and 7,238 shares of series C preferred stock that
will be reserved for issuance upon the exercise of options issued to former LISN
option holders. We expect that 1.25% of the common stock available for issuance
under the plan will be reserved for issuance upon exercise of options granted to
employees who were hired after the date of the LISN acquisition and that 3.0% of
the shares of common stock available for issuance under the plan will be
reserved for issuance upon exercise of options granted to employees who were
employees prior to the date of the LISN acquisition. In addition, a number of
shares of common stock equal to .75% of the shares of Parent's common stock
outstanding as of the consummation of the LISN acquisition will be reserved for
issuance to Mr. Mercurio, pursuant to the terms of his senior management
agreement, as described above under "-- Executive Employment Agreements."

              CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

GENERAL

     We have, from time to time, entered into various transactions with certain
of our officers, directors and principal stockholders and entities in which
these parties have an interest. We believe that these transactions have been on
terms no less favorable to us than could be obtained in a transaction with an
independent third party.

  Investor Rights Agreement

     In connection with the LISN acquisition, Parent and each of its
stockholders entered into an investor rights agreement. This agreement provides
that Parent's board of directors will be established at seven directors or any
higher number designated by Willis Stein & Partners. The agreement provides that
the board will consist of:

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

     - one person designated by Parent's stockholders prior to the LISN
       acquisition, provided that the designee is one of Parent's or Parent's
       subsidiaries' senior executives and the designee is reasonably acceptable
       to Willis Stein & Partners, and who initially will be Mr. Mullen;

     - one person designated by Willis Stein & Partners, provided that the
       designee is one of Parent's or Parent's subsidiaries' senior executives
       and the designee is reasonably acceptable to Parent's chief executive
       officer, and who will initially be Mr. Vanke; and

     - the remainder shall be designated by Willis Stein & Partners, and
       initially will be Mr. Stein, Mr. Froetscher, Mr. Barr and Mr. Reich.

     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

                                       69
<PAGE>   74

any equity securities to Willis Stein & Partners or its affiliates unless the
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.

  Put and Call Agreements

     In connection with the LISN acquisition, we entered into put and call
agreements with HIG Capital LLC ("HIG") and with some of our other stockholders.
We entered into the put and call arrangements as an accommodation to certain of
Parent's former stockholders for their personal tax planning. These agreements
granted us the right, through LISN, to acquire additional stock held by HIG and
by these stockholders. If we do not exercise our call, these stockholders have
the right to require us to purchase their shares. Our payment of the call price
is secured by letters of credit in the aggregate amount of $46.5 million under
the senior credit facilities, $40.8 million of which was drawn as of March 31,
2000. See "Description of Senior Credit Facilities."

     On March 1, 2000, we exercised our right to acquire the 7,546.38 shares of
series B preferred stock held by HIG and all accrued and unpaid dividends on
those shares, which constituted all of Parent's outstanding series B preferred
stock. We paid HIG $4.6 million for the option to repurchase its shares and an
aggregate of $39.4 million to the shares upon the exercise of our call.

     Under the call agreement with Parent's other stockholders, Parent was
granted the right to acquire an aggregate of 1,290,471.82 shares of Parent's
common stock, a portion of would be exchanged for newly issued shares of
Parent's series C preferred stock and junior subordinated notes. We paid these
stockholders an aggregate of $1.8 million for this call option. As of March 31,
2000, we had exercised our call option with respect to 295,901 of the shares.
The time period for exercise of both the put and call varies slightly with
respect to certain stockholders depending on the individual stockholder's
holding period with respect to its shares. The remainder of our call options are
expected to be exercised in the second and third quarters of 2000. The aggregate
amount of consideration that we would be required to pay if those stockholders
with outstanding puts exercised their put would be approximately $5.6 million in
cash, plus the issuance of 3,708 shares of Parent's series C preferred stock and
$2.6 million of Parent's junior subordinated notes.

  Pledge and Voting Agreements

     Pursuant to pledge and voting agreements, those stockholders that are
parties to the put and call agreements described above have granted LISN a
security interest in the stock that is subject to the call agreement to secure
their performance of their obligations under the call agreements. In addition,
these stockholders have appointed Parent's secretary to vote their shares in
favor or against all matters submitted to a vote of stockholders in the same
proportion as the other shares of our common stock are voted, provided that the
other shares of common stock are voted in accordance with the investor rights
agreement described above, and have agreed not to exercise any of their rights
with respect to the series C preferred stock.

  Consulting Agreement with Mr. Reich

     LISN is a party to a consulting agreement with Mr. Reich, who has served on
Parent's board of directors since the LISN Acquisition. This agreement provides
for consulting payments to Mr. Reich in an

                                       70
<PAGE>   75

amount of $15,000 per month. In exchange, Mr. Reich provides consulting services
for five days per month, in such areas as identifying and consummating
acquisitions, sales and marketing and human resources. LISN compensates Mr.
Reich for consulting in excess of five days per month at a rate of $3,000 per
day. The agreement is for a term beginning June 1, 1999 and expired November 30,
1999. We expect to assume this agreement and to extend the agreement through
June 1, 2000. Mr. Reich received options to purchase shares of LISN common stock
at the time this agreement was entered into, which were converted into options
to purchase 9,394.99 shares of Parent common stock and 634.92 shares of Parent
series C preferred in connection with the LISN acquisition.

RELATED PARTY LEASES

     Parent is a party to two leases with entities controlled by Mr. Ebersole, a
former director of Orius, for the lease of Channel's headquarters and office
space. The combined monthly rent for both leases is approximately $12,100. These
leases expire in April 2000 and April 2001, respectively. The lease expiring in
April 2000 has been on a year-to-year basis since 1995.

     U.S. Cable, Inc., a subsidiary of NATG, is a party to a lease agreement
with WMC Properties, a general partnership that is 25% owned by William Mullen,
a director of NATG. The lease is for U.S. Cable's headquarters and office space
located in O'Fallon, Missouri at a current rate of $61,800 per year, subject to
an increase of 3% per annum. The lease expires July 2003.

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
will be redeemed pursuant to a call agreement for an aggregate of $44.0 million
in cash. We entered into this call agreement with HIG as an accommodation to HIG
for its tax planning. 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.

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 March 31, 2000, there were
no shares of series A preferred stock, no shares of series B preferred stock,
196,748.05 shares of series C preferred stock, no shares of series D preferred
stock, 19,005,175.40 shares of class B common stock and 16,276,038.69 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. Upon the
exercise of all outstanding call options, each share of class B common will
automatically convert into one share of common stock. The number of votes per
share of series C preferred stock is subject to adjustment based on its
liquidation value per share. As of December 15, 2000, the series C preferred
stock was 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.

<PAGE>   78

JUNIOR SUBORDINATED NOTES

     As of March 31, 2000, there was $136.4 million of Parent's junior
subordinated notes outstanding. Following our exercise of our rights under call
agreements with certain of Parent's stockholders to acquire shares of their
stock during the second and third quarters of 2000, there will be $140.5 million
of junior subordinated notes outstanding.

     The LISN acquisition resulted in each stockholder of Parent, except to the
extent such 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 such 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 such 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>   79

                    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 provide for aggregate
borrowings of approximately $375.0 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, 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 March 31, 2000, there was $232.7 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) and $34.8 million available under
the senior credit facilities for working capital and other corporate purposes
and $75.0 million available for acquisitions. 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 intend to use a portion of the proceeds of this
offering 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. 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 December 30,
1999, our borrowings under the senior credit facilities bore interest at rates
ranging from 8.9% to 9.4%.

     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, 2000, (1) any such 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.

     Borrowings under the tranche A term loan are due December 15, 2004 and
borrowings under the tranche B term loan are due December 15, 2006. The tranche
A and tranche B term loans will be repaid pursuant to the following annual
amortization schedule, payable quarterly in arrears beginning March 31,

                                       75
<PAGE>   80

2000. The amortization schedule for the tranche B term loan will be adjusted
following the repayment of a portion of that loan with the proceeds of the
offering. See "Use of Proceeds."

     Prepayment Penalty on Tranche B Term Loan. If we repay all or any portion
of the tranche B term loan with the proceeds of a senior subordinated notes
offering, such as this offering, prior to December 15, 2001, we must repay the
tranche B term loan at 101% of the principal amount of that loan.

     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 such 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.

     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
leverage ratio, minimum fixed charge coverage ratio, minimum interest coverage
ratio and maximum capital expenditure tests. In addition, borrowings under the
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;

                                       76
<PAGE>   81

     - 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 after the original issue date, 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. Thereafter, 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
twelve-month

                                       78
<PAGE>   83

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.

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 1, 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;
provided that:

          (1) at least 65% of the aggregate principal amount of notes issued
     under the indenture remains outstanding immediately after the redemption;
     and

          (2) the issuers 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 pursuant to 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 such method as the trustee shall
     deem 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 thereof 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.
Notwithstanding the foregoing, payments and distributions made relating to the
notes pursuant to the trust described under "-- Legal Defeasance and Covenant
Defeasance" shall not be so 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

                                       79
<PAGE>   84

other like proceeding, whether or not such interest is an allowed claim in any
such proceeding, before the holders of notes will be entitled to receive any
payment or distribution of any kind or character with respect to any obligations
on, or relating to, the notes 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 with respect to any obligations on, or relating to, 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 (a "Payment
     Blockage Notice") from the representative of any Designated Senior Debt.

     Payments on and distributions with respect to any obligations on, or with
respect to, 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 (x) the date on
     which all nonpayment defaults are cured or waived, so long as no other
     event of default exists, (y) 180 days after the date on which the
     applicable Payment Blockage Notice is received or (z) 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 delivery of the initial Payment Blockage Notice
that in either case would give rise to a default pursuant to any provisions
under which a default previously existed or was continuing 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 December 31, 1999, on a pro forma basis, the aggregate amount of senior
debt outstanding would have been $251.4 million, excluding unused commitments of
$88.6 million under the senior secured credit agreement.

                                       80
<PAGE>   85

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 December 31, 1999 on a pro forma basis giving effect to the offering of
the outstanding notes:

     - outstanding senior debt of the guarantors would have been $251.4 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 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
pursuant to the offer described below (the "Change of Control Offer"), 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 (the "Change of Control Payment Date").
Holders electing to have a note purchased pursuant to 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 Change of Control Payment 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 such offer; or

                                       81
<PAGE>   86

          (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 pursuant to 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 pursuant to 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:

          (A) 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,

          (B) 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,

          (C) 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

          (D) make any Restricted Investment (each of the foregoing actions set
     forth in clauses (A), (B), (C) and (D) being referred to as a "Restricted
     Payment");

provided, that a Restricted Payment may be made, if at the time of the
Restricted Payment and immediately after giving effect to the Restricted
Payment,

          (a) no default or event of default shall have occurred and be
     continuing,

          (b) 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

          (c) the aggregate amount of Restricted Payments, including the
     proposed Restricted Payment, made subsequent to December 31, 1999 shall not
     exceed the sum of:

             (x) 50% of the cumulative Consolidated Net Income, or if cumulative
        Consolidated Net Income shall be a loss, minus 100% of such 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

             (y) 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

             (z) (i) the lesser of (I) 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 (II) the initial amount of that
        Investment; plus

             (ii) 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

                (iii) to the extent any Unrestricted Subsidiary of NATG is
           redesignated as a Restricted Subsidiary, the lesser of (I) the amount
           of NATG's initial Investment in the Unrestricted

                                       83
<PAGE>   88

           Subsidiary and (II) the fair market value of NATG's investment in the
           Unrestricted Subsidiary as of the date of its redesignation;

        provided, that no amount shall be included in this clause (z) 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 (i)
     solely in exchange for shares of Qualified Capital Stock of Parent, (ii)
     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 (iii) 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 shall have occurred and
     be 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; provided, that 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 shall have occurred and
     be 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
     pursuant to, and in compliance with, the put/call agreements certain 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 (c) of the
first paragraph of this covenant, amounts expended pursuant to clauses (1),
(2)(i), (2)(ii), (3), (4) and (6), in each case to the extent not duplicative of
amounts already included.

     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, pursuant to 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

                                       84
<PAGE>   89

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, which 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, provided, that if no
default or event of default shall have occurred and be 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 thereafter; provided, further, that 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
(each an "affiliate transaction") 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 at such time 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;

          (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 pursuant to, or the funding of, 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;

                                       85
<PAGE>   90

          (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 pursuant to 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, 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 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, (1) 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 (2) in
all other cases, the notes and guarantees are equally and ratably secured.

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

          (A) liens securing the senior secured credit agreement;

          (B) liens securing senior debt and liens securing senior debt of the
     guarantors;

          (C) liens securing the notes and the guarantees;

          (D) liens of an issuer or subsidiary guarantor on assets of any other
     issuer or subsidiary guarantor; and

          (E) permitted liens.

     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,
subordinated in right of payment to any other indebtedness of the person unless
the indebtedness (1) is incurred by an issuer or subsidiary guarantor and (2) 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

                                       86
<PAGE>   91

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 such 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 contained in contracts for sale of
     assets permitted by the indenture in respect of the assets being sold
     pursuant to those contracts pending the close of the sale, which
     encumbrance or restriction is not applicable to any asset other than the
     asset being sold pursuant to that contract;

          (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 so 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;

          (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 pursuant to an agreement referred
     to in clause (b) or (d) above, provided, that the provisions relating to
     the encumbrance or restriction contained in the indebtedness are 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

                                       87
<PAGE>   92

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 unless:

          (1) either

             (i) the issuer shall be the surviving or continuing corporation or

             (ii) the person, if other than the issuer, formed by such
        consolidation or into which the issuer is merged or the person which
        acquires by sale, assignment, transfer, lease, conveyance or other
        disposition the properties and assets of the issuer and its Restricted
        Subsidiaries substantially as an entirety (for purposes of this
        paragraph, the "Surviving Entity") (x) 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 (y) 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)(ii)(y) above, including giving effect
     to any indebtedness and Acquired Indebtedness incurred or anticipated to be
     incurred in connection with or in respect of 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,
     pursuant to 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)(ii)(y) 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 or in respect of 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 this indenture relating to the transaction have
     been satisfied. Notwithstanding the foregoing, the merger of an issuer with
     an affiliate incorporated solely for the purpose of reincorporating or
     similarly reorganizing such in another jurisdiction shall be permitted.

     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 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 unless:

          (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 thereof or the District of Columbia;

                                       88
<PAGE>   93

          (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 continuing corporation, the successor person formed
by the consolidation or into which the issuer is merged or to which the
conveyance, lease or transfer is made 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:

             (a) cash or cash equivalents;

             (b) any liabilities, as shown on NATG's or such Restricted
        Subsidiary's most recent balance sheet, of NATG or any such Restricted
        Subsidiary, other than liabilities that are by their terms subordinated
        to the notes, that are assumed by the transferee of the assets,

             (c) 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

             (d) any combination of the foregoing.

          (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 (A)
     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; provided that 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 and/or (B) 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

                                       89
<PAGE>   94

     Business ("replacement assets") and/or (C) to acquire all or substantially
     all of the assets of, or all of the voting stock of, another person engaged
     in a Permitted Business, provided, that if voting stock is acquired, the
     person becomes a subsidiary guarantor;

provided, that 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 an offer to purchase (the "Net Proceeds Offer") on
a date (the "Net Proceeds Offer Payment 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; provided, that 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 required pursuant to 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 pursuant to this
paragraph less the fair market value of all liabilities of the person related to
such property and assets not transferred shall be deemed to be Net Cash Proceeds
for purposes of this covenant.

     (c) Notwithstanding the foregoing provisions of this covenant, NATG and its
Restricted Subsidiaries will be permitted to consummate an Asset Sale without
complying with the foregoing 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;

provided, that 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 (c) shall constitute Net Cash
Proceeds subject to the provisions the foregoing provisions of this covenant.

                                       90
<PAGE>   95

     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 pursuant to 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 pursuant to 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 with respect to the issuers 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. Notwithstanding the foregoing, Orius Capital may engage in those
activities that are incidental to (A) the maintenance of is corporate existence
in compliance with applicable law, (B) legal, tax and accounting matters in
connection with any of the foregoing activities and (C) entering into, and
performing its obligations under, the Documents to which it is a party.

     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, or, if Parent shall
     cease to own more than a majority of the voting securities of NATG, of NATG
     and its consolidated subsidiaries, showing in the case of Parent's
     financial statements, in reasonable detail, either on the face of the
     financial statements or in the related footnotes, the information required
     to be presented with respect to the issuers and the guarantors under Staff
     Accounting Bulletin 53 or any successor interpretation or rule of the SEC
     and, 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;

                                       91
<PAGE>   96

          (2) 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 contemplated by a
registration rights agreement, 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, and 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 pursuant to 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 pursuant to 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. Thereafter, 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
pursuant to 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. Thereafter, the subsidiary shall be a guarantor for all purposes
of the indenture.

     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, waive or agree to amend in the
time frame set forth in the solicitation documents relating to the consent,
waiver or agreement.

     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,
assign, pledge or otherwise encumber or dispose of any shares of capital stock
or other equity securities of any Restricted Subsidiary of NATG, except (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;

                                       92
<PAGE>   97

          (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 such 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; provided that NATG or its
     Restricted Subsidiary shall have a 20-day grace period to cure the
     foregoing 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) (i) 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 (ii) 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 (iii) Parent or any other guarantor shall default
     in the due performance or observance of any term, covenant or agreement on
     its part to be performed or observed, after giving effect to any applicable
     grace periods, pursuant to 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" (the
"acceleration notice"), and the same:

          (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.

                                       93
<PAGE>   98

     The indenture provides that, at any time after a declaration of
acceleration with respect to the notes as described in the preceding paragraph,
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.

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 respect of the notes or for any claim based on, in
respect of or by reason of those obligations or their creation; provided, that
the foregoing 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 ("Legal Defeasance").

                                       94
<PAGE>   99

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 ("Covenant Defeasance") and thereafter any
omission to comply with those covenants shall not constitute a default or event
of default with respect to 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 foregoing, 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;

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

                                       95
<PAGE>   100

     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 provided for or 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.

     Notwithstanding the foregoing, the opinion of counsel required by clause
(2) above with respect to a 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,
     for principal of, premium, if any, and interest on the notes 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

     (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.

                                       96

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 such 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 (a) an opinion of counsel
and (b) 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 the modification or amendment, 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
     such note on or after the due date thereof or to bring suit to enforce such
     payment;

          (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 (i) Parent or (ii) 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 such duties as are specifically set forth
in the indenture or the TIA. During the existence of an event of default, the
trustee will exercise such 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 certain limitations on
the rights of the trustee, should it become a creditor of an issuer, to obtain
payments of claims in certain cases or to realize on certain 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; provided that if the
trustee acquires any conflicting interest as described in the TIA, it must
eliminate the conflict or resign.

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 proceeds from the incurrence or repayment, other than the incurrence or
     repayment of indebtedness in the ordinary course of business for working
     capital purposes pursuant to working capital facilities, occurring during

     four quarter period and on or prior to the Transaction Date, as if the
     incurrence or repayment, as the case may be, and the application of the

     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 such
Restricted Subsidiary had directly incurred or otherwise assumed the guaranteed
indebtedness, calculated to avoid duplication. Furthermore, in calculating
"Consolidated Fixed Charges" for purposes of determining the denominator, but
not the numerator, of this "Consolidated Fixed Charge Coverage Ratio,"

          (a) interest on outstanding indebtedness, determined on a fluctuating
     basis as of the Transaction Date and which will continue to be so
     determined of the Transaction 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 the Transaction Date;

     Transaction Date 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 the Transaction
     Date will be deemed to have been in effect during the Four Quarter Period;
     and

          (c) notwithstanding clause (a) 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

     of those agreements.

     "Consolidated Fixed Charges" shall mean, with respect to any person for any
period, the sum, without duplication, of

          (1) Consolidated Interest Expense, before amortization or write-off of

          (2) to the extent not included in Consolidated Interest Expense, the
     product of

             (x) 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 such period, times

             (y) a fraction, the numerator of which is one and the denominator
        of which is one minus the then current effective consolidated federal,
        state and local tax rate of that person, expressed as a decimal.

     "Consolidated Interest Expense" shall mean, with respect to any person for
any period, the sum of, without duplication:

          (1) the aggregate of the interest expense of that person and its
     Restricted Subsidiaries for the period determined on a consolidated basis
     in accordance with GAAP, including without limitation,

     paid to that person or any of its Restricted Subsidiaries by such 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 such first person or is merged into

     Subsidiaries or whose assets are acquired by such first person or any of
     its Restricted Subsidiaries,

          (3) the income of any subsidiary of such first person to the extent

     judgment, decree, order, statute, rule or governmental regulation
     applicable to that Restricted Subsidiary,

     For purposes of computing Consolidated Net Income, but only to the extent
used in determining the Consolidated Fixed Charge Coverage Ratio, there shall be
excluded from the computation, without duplication and to the extent not
otherwise excluded from the computation, non-recurring fees and expenses
incurred in connection with the consummation of any Asset Acquisition in an
aggregate amount not to exceed 5% of the total consideration for the Asset
Acquisition.

                                       103
<PAGE>   108

provided, that the term "Contingent Obligation" shall not include endorsements

is redeemable at the sole option of the holder of the capital stock on or prior
to the maturity date. Notwithstanding the preceding sentence, any capital stock
that would constitute Disqualified Capital Stock solely because the holder of

upon the occurrence of a change of control or an asset sale, each such term
being defined in substantially the same manner as the corresponding terms in 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

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 such
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 such 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 thereafter 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 pursuant to 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, thereby eliminating 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.

     Pursuant to 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 thereof 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 such 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
thereof 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 such 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.

                                       119
<PAGE>   124

     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, such
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 such 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 such procedures, and such 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 such issuance, the trustee is

                                       120
<PAGE>   125

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 such person 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.

                                       122
<PAGE>   127

  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 such 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 pursuant to either a tax treaty or the portfolio interest
exemption. Copies of these information returns may also be available to the tax

                                       124
<PAGE>   129

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 pursuant to 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.

                                       125
<PAGE>   130

     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 pursuant to the exchange offer may be sold
from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the exchange notes or
a combination of 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 pursuant to 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 any such persons may be deemed to be underwriting
compensation under the Securities Act. The letter of transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
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 thereof 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.

                       REPORT OF INDEPENDENT ACCOUNTANTS

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.

                   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. The combination of LISN Holdings, Inc. and LISN, Inc. has been
accounted for in a manner similar to a pooling of interests because the entities
were under common control and, 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 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

                                       F-9

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY LISN HOLDINGS, INC.)

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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 second 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-12
<PAGE>   145
          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, 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.

     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.

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):

occurred if the combination had taken place on the basis assumed above, nor are
they indicative of the results of future combined operations.

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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     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
follows:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     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
agreement to one of the investees. The investment value at December 31, 1999 is
zero.

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.

CAPITAL LEASE OBLIGATIONS AND EQUIPMENT LOANS

     Certain subsidiaries have obligations outstanding under capital leases and
other equipment financing arrangements. The remaining obligations are payable in
monthly installments expiring at various dates through June 2003.

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 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. 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 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 $13.38.
The purchase price of $1,000 per share and the value per common share of $13.38
were based upon the values of the preferred and common stock purchased in
connection with the Orius/LISN transaction.

     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 reflects the adjustment to the preferred stock held by the
former LISN shareholders.

     The expected provision for income taxes at the statutory Federal income tax
rate and the actual provision for the period ended December 31, 1999 differs due
primarily to the effects of state taxes and non-deductible goodwill
amortization.

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.

     Identifiable assets for each operating segment at December 31, 1999 are as
follows:

21. COMMITMENTS AND CONTINGENCIES

LEASES

     The Company occupies certain facilities under noncancelable lease
agreements classified as operating leases expiring at various dates through

certain vehicles and equipment under noncancelable operating agreements.
Aggregate rental expense was approximately $559,000 and $313,000 for the years
ended December 31, 1999 and 1998, respectively. Future minimum lease commitments
under these leases are as follows:

</TABLE>

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
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, the Company 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.

     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.

                       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

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 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 into NATG with NATG as the surviving corporation. As a result of the
Reorganization, NATG became

          ORIUS CORP. AND SUBSIDIARIES (FORMERLY NATG HOLDINGS, INC.)

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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.

     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

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.

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:

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
outstanding under the old credit facility, the deferred financing costs
associated with the old credit facility totaling $1,348,000 were written off
resulting in an extraordinary charge to income of $770,000, net of tax benefits
of $578,000.

CAPITAL LEASE OBLIGATIONS AND EQUIPMENT LOANS

     In addition to the borrowings under the credit facility, certain
subsidiaries have obligations outstanding under capital leases and other
equipment financing arrangements. The remaining obligations are payable in
monthly installments expiring at various dates through June 2003.

MATURITIES

     At December 14, 1999, the estimated aggregate annual repayments for notes
payable and capital lease obligations are as follows:

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:

         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,
approximately 36% and 56%, respectively, of the contract revenues were from
three customers (TCI, Time Warner, and MediaOne), with the largest customer
representing approximately 16% and 24%, 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 were approximately
$4,325,647 and $1,183,300, respectively.

Kenya Corporation and Subsidiary
Sheboygan, Wisconsin

     We have audited the accompanying consolidated balance sheet of Channel
Communications, Inc. (f/k/a Kenya Corp.) as of December 31, 1997, and the
related consolidated statements of income and retained earnings and cash flows
for the year then ended. 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 in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to in the
first paragraph present fairly, in all material respects, the consolidated
financial position of Kenya Corporation and subsidiary as of December 31, 1997,
and the consolidated results of their operations and their consolidated cash
flows for the year then ended in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Nature Of Business -- Channel Communications, Inc.'s (f/k/a Kenya
Corporation, the Company) constructs and installs cable television systems
throughout the United States. See Note 6 regarding concentration of business
with significant customers.

     Principles Of Consolidation -- The consolidated financial statements
include the Company and its wholly-owned subsidiary, 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. 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,
allowance for doubtful accounts, depreciation and amortization, and in the
estimated lives of assets.

     Revenues -- The Company's revenue consists principally of unit contracts.
Consequently, the Company accounts for revenue and related costs 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. At the time a loss on a
contract becomes known, the entire amount of the estimated ultimate loss is
accrued. Deferred revenues consist principally of prepayments by customers for
the cost of material and services to be provided and are recognized as revenues
as the related material is used or services are provided.

     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 service 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 retired, the cost and related accumulated depreciation
are removed from the accounts and the resulting gain or loss is included in
income.

     Fair Value Of Financial Instruments -- The fair value of the Company's
financial instruments approximate the carrying values.

     Income Taxes -- The Company, with the consent of its stockholder, has
elected to be an S corporation under the Internal Revenue Code. In lieu of
corporation income taxes, the stockholders of an S corporation are taxed on
their proportionate share of the company's taxable income. Therefore, no
provision or liability for federal and state income taxes has been included in
the financial statements (see Note 5.)

4. DEBT AND CAPITAL LEASE OBLIGATIONS

     At December 31, 1997, the Company had a revolving line-of-credit with a
bank for $2,500,000. At December 31, 1997, none of the line-of-credit had been
drawn.

5. 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. The provision for income taxes also includes current year corporate
level state and local income taxes.

6. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK

                         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 a provider of installation, design,
engineering and maintenance services for the telecom industry, formerly in the
western United States. The Company is headquartered in Nampa, Idaho, and has
offices in Twin Falls and Pocatello, Idaho.

     On February 26, 1999, the Company was sold to Orius Corp. 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. Pro forma income taxes are calculated at a combined federal and
state tax rate of 38%.

     Subsequent to the acquisition 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
$100,000 and $100,000 for 1997 and 1998, respectively.

6. TRANSACTIONS WITH RELATED PARTIES:

     During 1998, 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. The lease agreements contain two
five-year renewal options, at which time lease terms will be renegotiated.
Rental expense for these leases totaled $169,200 and $155,000 for 1997 and 1998,
respectively.

     The Company paid consulting fees to businesses owned by related parties.
These businesses provided property management, product development, and other
services to the Company. Consulting fees were $149,996 and $152,000 for 1997 and
1998, respectively. As a result of the acquisition, these services will no
longer be provided by these related parties.

     At December 31, 1997 and 1998, the Company had related party receivables of
$5,027 and $9,477, respectively; and had related party payables of $14,100 and
$13,007, respectively.

7. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK:

     In 1997, revenues from three customers, US West, Citizens and Idaho Power,
represented approximately 50%, 16%, and 15% of total revenue; and in 1998,
revenues from three customers represented approximately 41%, 13%, and 12% 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.

                         NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

     The Company is a provider of installation, design, engineering and
maintenance services for the telecom industry. The company operates in the St.
Louis metropolitan area, as well as throughout the United States.

REVENUE AND COST RECOGNITION

     Revenues from fixed price contracts are recognized on the
percentage-of-completion method for individual contracts. Revenues are
recognized based on fixed prices per contract for amount of work performed.
Changes in job performance, estimated profitability and final contract
settlements may result in revisions to costs and income, and are recognized in
the period in which the revisions are determined.

     Contract costs include all direct materials, subcontracts, labor costs and
those indirect costs related to contract performance. General and administrative
costs are charged to expenses as incurred.

CASH EQUIVALENTS

     For purposes of the statement of cash flows, the Company considers all
short-term debt securities purchased with a maturity of three months or less to
be cash equivalents.

ACCOUNTS RECEIVABLE, TRADE

     Trade accounts receivable are recorded net of allowance for doubtful
accounts of $40,000 at December 31, 1998.

INVENTORY

     Materials are valued at cost on the first-in, first-out (FIFO) method.

PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment is stated at cost. Depreciation has been
provided for in the financial statements using accelerated methods over the
estimated useful lives. Repairs and maintenance are charged to expense in the
year incurred. Additions and improvements are capitalized.

OTHER ASSETS

     At December 31, 1998, other assets consist of the following:

<TABLE>
<S>                                                           <C>

                                                              $19,332
                                                              =======
</TABLE>

ACCRUED HEALTH INSURANCE

     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 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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

LEASE AGREEMENTS

     Annual rentals pertaining to leases which convey merely the right to use
property are charged to current operations. Leases which are in substance
installment purchases of property are recorded as acquisitions with the asset
and the related obligation recorded in the balance sheet.

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.

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.

2. INVENTORY

     Inventory consists of the following:

                   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.

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 and $15,219,596
for fiscal years 1997 and 1998, which comprises approximately 34.2% and 43.5%,
respectively.

2. SHORT-TERM INVESTMENTS:

     Short-term investments at December 31, 1998 consist of municipal bonds with
an approximately 5.60% effective annual yield. The market value of these
investments approximated cost at December 31, 1998.

</TABLE>

     Recoverable income taxes totaling $94,103 reported in the accompanying
December 31, 1998 balance sheet result from federal and state estimated tax
payments which exceeded the Company's current income tax obligations.

9. OPERATING LEASE COMMITMENTS:

     The Company leases office and shop facilities in Clackamas, Oregon and
Sacramento, California from its stockholders under lease agreements which
require the Company to pay certain operating costs such as property taxes,
insurance and utilities in addition to the basic rent.

     The combined rent commitment under these leases is $19,000 per month
through February 2004, exclusive of operating costs.

     Rent expense charged to operations under all operating leases, including
the leases with the Company's stockholders described above, totaled
approximately, $1,719,100 and $1,085,000 for 1997 and 1998, respectively. Rent
expense paid to a related party was $168,000 for each of the years ended 1997
and 1998.

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 and $604,000 for 1997
and 1998, 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 and $54,000, for the years ended December 31, 1997 and 1998,
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.

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.

                               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.

     The shareholder of the Company has signed a definitive agreement to sell
all of the Company's outstanding shares to Orius Corporation. The transaction is
expected to close on May 24, 1999.

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.

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>

Machinery and equipment.....................................   5.5 years
Automobiles.................................................   5.5 years

Leasehold improvements......................................  31.5 years
</TABLE>

     Depreciation expense in 1997 and 1998 was $83,767 and $101,434,
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 and $11,246,000 in 1997 and 1998, respectively.
These amounts represent sales to 2 and 3 customers, respectively.

4. ACCOUNTS RECEIVABLE

     Accounts receivable consisted of the following at December 31:

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 in recent years, the retention balances at December 31, 1997 and 1998
are expected to be collected within twelve months of year end.

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:

              PART II: INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20: INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The following is a summary of the statutes, charter and bylaw provisions or
other arrangements under which the Registrants' directors and officers are
insured or indemnified against liability in their capacities as such. All of the
directors and officers of the Registrants are covered by insurance policies
maintained and held in effect by Orius Corp. against certain liabilities for
actions taken in their capacities as such, including liabilities under the
Securities Act.

REGISTRANTS INCORPORATED UNDER DELAWARE LAW

     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
incurred by him in any indemnified capacity, or arising out of his status as
such, regardless of whether the corporation would otherwise have the power to
indemnify him under the Delaware Statute.

     Orius Capital Corp. and Arion Sub, Inc. The certificates of incorporation
of each of Orius Capital Corp. and Arion Sub, Inc. provide that, to the fullest
extent permitted by the Delaware Statute, no director of the corporation shall
be liable to the corporation or its stockholders for monetary damages for a
breach of fiduciary duty as a director.

     The bylaws of each of Orius Capital Corp. and Arion Sub, Inc. provide that
each person who was or is made a party or is threatened to be made a party to or
is involved in proceeding by reason of the fact that he or she, or a person of
whom he or she is the legal representative, was serving in an indemnified
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

                                      II-1
<PAGE>   226

under the corporation's certificates of incorporation or under any statute,
bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

     Irwin Telecom Holdings, Inc. Irwin Telecom Holdings, Inc.'s certificate of
incorporation provides that no director of the corporation shall be liable to
the corporation or its stockholders for monetary damages for a breach of
fiduciary duty as a director, except for liability (1) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (2) for acts
or omissions not in good faith or which involve intentional misconduct or
knowing violation of law, (3) under Section 174 of the Delaware Statute for the
unlawful payment of dividends, or (4) for any transaction from which the
director derived any improper personal benefit.

     Irwin Telecom Holdings, Inc.'s bylaws further provide that each person who
was or is made a party or is threatened to be made a party to a proceeding, by
reason of the fact that he or she, or a person of whom he or she is the legal
representative, was serving in an indemnified capacity, shall be indemnified and
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
which any person has under the corporation's certificates of incorporation or
under any statute, bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.

REGISTRANTS FORMED UNDER THE DELAWARE LIMITED LIABILITY COMPANY ACT

     NATG Holdings, LLC is a limited liability company formed under the laws of
the state of Delaware. Section 18-108 of the Delaware Limited Liability Company
Act provides that, subject to any standards and restrictions, if any, set forth
in a company's limited liability company agreement, a limited liability company
may indemnify and hold harmless any member or manager or other person from and
against any and all claims and demands whatsoever.

     Article XIII of NATG Holdings, LLC's Amended and Restated Limited Liability
Company Agreement provides that to the greatest extent not inconsistent with the
laws and public policy of Delaware, it will indemnify, as a matter of right, any
member, any member's representative, officers, directors, shareholders,
employees and agents and any of its officers who are made a party to any
proceeding because such member or individual is or was a member or an officer,
representative, director, shareholder, employee or agent of a member or any of
its officers against all liability incurred by such member or individual in
connection with any such action or proceeding.

REGISTRANTS INCORPORATED UNDER FLORIDA LAW

     Orius Corp., North American Tel-Com Group, Inc., Statewide CATV, Inc.,
Excel Cable Construction, Inc. and Fenix Holdings, Inc., are incorporated under
the laws of the state of Florida. Section 607.0850 of the Florida Business
Corporation Act (the "Florida Statute") provides that a corporation may
indemnify directors and officers, as well as other employees and agents, along
with a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses incurred in legal
proceedings connected with their service to the corporation, if he or she acted
in good faith and in a manner he or she reasonably believed to be in, or not
opposed to, the best interests of the corporation and, had no reasonable cause
to believe his or her conduct was unlawful. In the case of a proceeding brought
by or in the right of the corporation, the corporation may also indemnify
directors and officers as provided above, except that no indemnification may be
made in respect of any claim or issue as to which a person is adjudged liable to
the corporation unless a court rules that such person is fairly and reasonably
entitled to indemnification despite the adjudication of liability. Where an
officer or director is successful on the merits or otherwise in the defense of
any action referred

                                      II-2
<PAGE>   227

to above, the corporation must indemnify him against the expenses which such
officer or director has actually and reasonably incurred.

     The Florida Statute provides that its indemnification provisions are not
are not exclusive and that a corporation may make any further indemnification of
its directors, officers, agents and employees unless a judgment or other final
adjudication establishes that the persons action or omissions were material to
the cause of action and constituted:

          (1) a violation of criminal law, unless the person had reasonable
     cause to believe his conduct was lawful;

          (2) a transaction in which the person derived improper personal
     benefit;

          (3) in the case of a director, for unlawful distributions under the
     Florida Statute; and

          (4) willful misconduct or a conscious disregard for the best interests
     of the corporation in a proceeding by or in the right of the corporation or
     a shareholder.

     The Florida Statute further 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 him and incurred by
him in any such capacity, arising out of his status as such, regardless of
whether the corporation would otherwise have the power to indemnify him under
the Florida Statute.

     Orius Corp. and North American Tel-Com, Inc. Orius Corp.'s and North
American Tel-Com Inc.'s respective articles of incorporation provide that, to
the fullest extent permitted by the Florida Statute, a director of the
corporation shall not be liable to the corporation or its shareholders for
monetary damages for breach of fiduciary duty as a director.

     Their respective bylaws provide that any person, his heirs, or personal
representative, made, or threatened to be made, a party to any threatened,
pending, or completed proceeding, because he served in an indemnified capacity,
shall be indemnified by the corporation, and the corporation may advance his
related expenses to the full extent permitted by Florida law. In discharging his
duty, any director, officer, employee, or agent, when acting in good faith, may
rely upon information, opinions, reports, or statements, including financial
statements and other financial data, in each case prepared or presented by (1)
one or more officers or employees of the corporation whom the director, officer,
employee, or agent reasonably believes to be reliable and competent in the
matters presented, (2) counsel, public accounts, or other persons as to matters
that the director, officer, employee, or agent believes to be within that
person's professional or expert competence, or (3) in the case of a director,
reasonably believes that the committee is competent. Their bylaws further
provide that the foregoing right of indemnification or reimbursement shall not
be exclusive of other rights to which the person, his heirs, or personal
representatives may be entitled and that the corporations may, upon the
affirmative vote of a majority of their respective boards of directors, purchase
insurance for the purpose of indemnifying these persons.

     State Wide CATV, Inc. State Wide CATV, Inc.'s bylaws provide that the
corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any proceeding by reason of the fact that he or she is or was
serving in an indemnified capacity, against expenses, including attorneys' fees,
judgments, fines, and amounts paid in settlements, actually and reasonably
incurred by him or her in connection with such proceeding, including any appeal
of such action, if he or she acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe such conduct was unlawful. However, no
indemnification shall be provided in any action or suit by or in the right of
the corporation to procure a judgment in its favor, with respect to any claim,
issue, or matter as to which such person is adjudged to be liable for negligence
or misconduct in the performance of his or her duty to the corporation.

     Excel Cable Construction, Inc. Excel Cable's articles of incorporation
provide that, to the fullest extent permitted by the Florida Statute, a director
of the corporation shall not be liable to the corporation or its shareholders
for monetary damages for breach of fiduciary duty as a director. Excel Cable's
bylaws
                                      II-3
<PAGE>   228

provide that the corporation shall indemnify each of its directors and officers,
whether or not then in office (and his executor, administrator and heirs),
against all reasonable expenses actually and necessarily incurred by him in
connection with the defense of any litigation to which he may have been made a
party because he is or was a director or officer of the corporation. He shall
have no right to reimbursement, however, in relation to matters as to which he
has been adjudged liable to the corporation for negligence or misconduct in the
performance of his duties. The right to indemnity for expenses will also apply
to the expenses of suits which are compromised or settled if the court having
jurisdiction of the matter shall approve such settlement. Excel Corporation's
bylaws further provide that the right to indemnification provided in the bylaws
shall be in addition to and not exclusive of, all other rights to which such
director or officer may be entitled including, without limiting the generality
of the expenses as provided in Section 608.13 (14) (15) and (16) of the Florida
Statute and that the board of directors of the corporation may authorize the
purchase and maintenance of insurance to the extend provided in Section
608.13(17) of the Florida Statute.

     Fenix Holdings, Inc.'s articles of incorporation provide that the
corporation shall indemnify any present or former officer or director, or person
exercising powers and duties of an officer or director, to the full extent
permitted by law.

REGISTRANTS INCORPORATED UNDER IDAHO LAW

     DAS-CO of Idaho, Inc. is incorporated under the laws of the state of Idaho.
Sections 30-1-851 and 30-1-856 of the Idaho Business Corporation Act (the "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
was a director or officer of the corporation, if he conducted himself in good
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.
DAS-CO's articles of incorporation provide that the board of directors is
entitled to determine the terms of the indemnification, including the
advancement of expenses.

REGISTRANTS INCORPORATED UNDER KANSAS LAW

     Channel Communications, Inc. is incorporated under the laws of the state of
Kansas. Under Section 17-6305 of the Kansas General Corporation Code (the
"Kansas Statute"), a corporation may indemnify any person serving in an
indemnified capacity against expenses, including attorneys' fees, judgments,
fines and amounts paid in settlement actually and reasonably incurred by him if
he acted in

                                      II-4
<PAGE>   229

good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the corporation and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
Similar provisions apply to actions brought by or in the right of the
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless a court determines that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnification for such expenses as
the court shall deem proper. 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 Kansas Statute further provides that a corporation may purchase and
maintain insurance on behalf of any person serving in an indemnified capacity
against any liability asserted against him and incurred by him in any such
capacity, arising out of his status as such, regardless of whether the
corporation would otherwise have the power to indemnify him under the Kansas
Statute.

     Channel's articles of incorporation and bylaws do not contain provisions
regarding indemnification.

REGISTRANTS INCORPORATED UNDER MICHIGAN LAW

     Mich-Com Cable Services Incorporated is incorporated under the laws of the
state of Michigan. Under the Michigan Business Corporation Act (the "Michigan
Statute"), a corporation is permitted it to indemnify any person who was, is or
is threatened to be made a party to any proceeding, other than an action, suit
or proceeding by or in the right of the corporation, by reason of the fact that
he or she was serving in an indemnified capacity against expenses, including
attorney fees, and judgments, penalties, fines and amounts paid in settlement
that are actually and reasonably incurred by him or her in connection with the
proceeding, if the indemnified person acted in good faith and in a manner he or
she reasonably believed to be in, or not opposed to, the best interests of the
corporation or its shareholders, and with respect to a criminal action or
proceeding, if he or she had no reasonable cause to believe his or her conduct
was unlawful. Similar provisions apply to actions brought by or in the right of
the corporation, except that no indemnification shall be made without judicial
approval with respect to a claim, issue, or matter in which the indemnified
person has been found 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.

     The Michigan Statute further provides that its provisions concerning
indemnification and advancement of expenses are not exclusive of other rights to
which a person seeking indemnification or advancement of expenses may be
entitled under a corporation's articles of incorporation, its bylaws or a
contractual arrangement. In addition, the Michigan Statute 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
him and incurred by him in any such capacity, arising out of his status as such,
regardless of whether the corporation would otherwise have the power to
indemnify him under the Michigan Statute.

     Mich-Com Cable Service's bylaws provide that a director of the corporation
shall not be personally liable to the corporation or its shareholders for
monetary damages for breach of fiduciary duty as a director, except for
liability:

          (1) for any breach of the director's duty of loyalty to the
              corporation or its shareholders;

          (2) for acts or omissions not in good faith or that involve
              intentional misconduct or knowing violation of law;

          (3) for unlawful distributions under Section 551(1) of the Michigan
              Statute; and

          (4) for any transaction from which the director derived an improper
              personal benefit.

REGISTRANTS INCORPORATED UNDER MISSOURI LAW

of Missouri. Under Section 351.355 of the General and Business Corporation Law
of Missouri (the "Missouri Statute"), a corporation may indemnify any persons
who are, or are threatened to be made, parties to any threatened, pending or
completed proceeding, other than an action by or in the right of such
corporation, by reason of the fact that such person is or was serving in 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 is permitted without
judicial approval if the officer or director is adjudged to be liable for
negligence or misconduct in the performance of his duty 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.

     The Missouri Statute also permits such persons to seek indemnification
under any applicable bylaw, agreement, vote of stockholders or disinterested
directors or otherwise. The Missouri Statute also permits a corporation to
provide further indemnity, in addition to that otherwise contemplated by the
Missouri 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 conduct which is finally adjudged to have been
knowingly fraudulent, deliberately dishonest or willful misconduct. The Missouri
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
Missouri Statute.

     Schatz Underground Cable's certificate of incorporation provides that each
present or former director or officer or other person serving in an indemnified
capacity, and his legal representatives, shall be indemnified by the corporation
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 in neither case shall the corporation indemnify such persons with respect
to any matters as to which he shall finally be adjudged in any such action, suit
or proceeding, to have been liable for negligence or misconduct in the
performance of his duties as such director or officer. The indemnification in
Schatz's certificate of incorporation shall apply also in respect of any amount
paid in compromise of any proceeding asserted against such director or officer,
provided the board of directors shall have first approved the proposed
compromise settlement and determined that the officer or director involved was
not guilty of negligence or misconduct. The right to indemnification under
Schatz's certificate of incorporation are not be exclusive of any other rights
to which its directors or officers may be lawfully entitled.

REGISTRANTS INCORPORATED UNDER NORTH CAROLINA LAW

     CATV Subscriber Services, Inc. is incorporated under the laws of the state
of North Carolina. Sections 55-8-52 and 55-8-56 of the North Carolina Business
Corporation Act (the "North Carolina Statute") require a corporation, unless its
articles of incorporation provide otherwise, to indemnify a director or officer
who has been wholly successful, on the merits or otherwise, in the defense of
any proceeding to which such director or officer was, or was threatened to be,
made a party because he is or was a director or officer of the corporation
against reasonable expenses incurred by him in connection with the proceeding.

     In addition, the Section 55-8-51 of the North Carolina Statute provides
that a corporation may indemnify an individual made a party because he is or was
a director or officer of the corporation if he conducted himself in good faith
and reasonably believe his conduct was in the best interests of the

                                      II-6
<PAGE>   231

corporation. The corporation may not indemnify an individual in connection with
a proceeding by or in the right of the corporation if the individual was
adjudged liable to the corporation in the proceeding or, in connection with any
other proceeding, if the individual was was adjudged liable on the basis that
personal benefit was improperly received by him. Unless prohibited by the
articles of incorporation, a director or officer also may make application and
obtain court-ordered indemnification if the court determines that such director
or officer is fairly and reasonably entitled to such indemnification as provided
in Sections 55-8-54 and 55-8-56 of the North Carolina Statute. A corporation may
also indemnify its employees, officers and agents to the same extent it
indemnifies its directors. CATV's articles of incorporation and bylaws do not
contain provisions concerning indemnification.

     Additionally, Section 55-8-57 of the North Carolina Statute authorizes a
corporation to purchase and maintain insurance on behalf of an individual who is
or was a director, officer, employee or agent of the corporation against certain
liabilities incurred by such a person, whether or not the corporation is
otherwise authorized by the North Carolina Statute to indemnify that person.

REGISTRANTS INCORPORATED UNDER OHIO LAW

     LISN Company and LISN, Inc. are incorporated under the laws of the state of
Ohio. Section 1701.13(E) of the Ohio Revised Code (the "Ohio Statute") allows
indemnification by a corporation to any person made or threatened to be made a
party to any proceeding, other than a proceeding by or in the right of the
corporation, by reason of the fact that he is or was serving in an indemnified
capacity, against expenses, including judgment and fines, if he 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 criminal actions, in which he
had no reasonable cause to believe that his conduct was unlawful. Similar
provisions apply to actions brought by or in the right of the corporation,
except that no indemnification shall be made in the person shall have been
adjudged to be liable for negligence or misconduct to the corporation unless a
court determines that the person, in view of all of the facts and circumstances
of the case, is fairly and reasonably entitled to indemnification. Where an
officer or director or other indemnified person s 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 Ohio Statute further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, 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 against any liability asserted against him and incurred by him in any
such capacity, arising out of his status as such, regardless of whether the
corporation would otherwise have the power to indemnify him under the Ohio
Statute. The indemnification provided under the Ohio Statute is not exclusive
and is in addition to any indemnification provided under a corporation's
articles, regulations or other agreement.

     LISN, Inc.'s code of regulations provides that, to the fullest extent
authorized or permitted by law, the corporation shall indemnify and save
harmless any and all of its past, present and future shareholders, directors and
officers; and, if the board of directors so determines, any employees and other
agents of the corporation acting in any capacity at the request of or on behalf
of the corporation from and against any and all expenses, fees, liabilities or
amounts paid in settlement (including, but not limited to, attorneys' fees and
court costs) reasonably incurred by an indemnified individual with respect to
any threatened, pending or completed proceeding under which the indemnified
individual is a party or participant because of actions or omissions of the
corporation or any shareholder, director, officer, employee, agent or other
person acting in any capacity at the request of or on behalf of the corporation.
LISN Company's code of regulations provide for similar indemnification, but
prohibit indemnification for gross negligence or willful misconduct.

     In addition, LISN Inc.'s and LISN Company's respective codes of regulations
provide that, whether or not the indemnification, provisions in the code of
regulations apply, the corporation may purchase and maintain insurance upon
and/or furnish similar protection for any indemnified individual to cover any

                                      II-7
<PAGE>   232

liability such indemnified individual might incur from the exercise of the
indemnified individual's duties for the corporation or the indemnified
individual's capacity as an agent or representative of the corporation.

REGISTRANTS INCORPORATED UNDER OREGON LAW

     Copenhagen Utilities & Construction, Inc. is incorporated under the laws of
the state of Oregon. The Oregon Business Corporation Act provides that an Oregon
corporation may indemnify any individual made a party to a proceeding because
the individual is or was a directors, other than an action by or in the right of
the corporation, if the person concerned acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
corporation, was not adjudged liable on the basis of receipt of an improper
personal benefit and, with respect to any criminal action or proceeding, had no
reasonable cause to believe the conduct was unlawful. Similar provisions apply
with respect to actions by or in the right of the corporation, except that no
right of indemnification will be granted if the person is adjudged to be liable
to the corporation. Every person who has been wholly successful, on the merits
or otherwise, in the defense of any proceeding described above is entitled to
indemnification as a matter of right. In addition, a corporation may obtain
insurance for the protection of its directors and officers against any liability
asserted against them in their official capacities whether or not the
corporation would be able to indemnify such persons under Oregon law. The rights
of indemnification described above are not exclusive of any other rights of
indemnification to which the persons indemnified may be entitled under any
bylaw, agreement, vote of shareholders or directors or otherwise.

     Copenhagen Utilities' articles of incorporation provide that directors of
the corporation shall, to the fullest extent permitted by Oregon law, not be
liable to the corporation or its shareholders for monetary damages for his
conduct as a director. Copenhagen Utilities' articles of incorporation further
provide that the corporation is authorized, to the fullest extent permitted
Oregon law and subject to its bylaws, to indemnify any of its officers,
directors, employees and agents, and that the board of directors of the
corporation is entitled to determine the terms of the indemnification, including
the advancement of expenses.

     Copenhagen Utilities' bylaws provide that, unless prohibited by the Oregon
Statute, each person who was or is made a party or is threatened to be made a
party to or is involved in any threatened, pending, or completed proceeding by
reason of the fact that he or she was serving in an indemnified capacity, shall
be indemnified and held harmless by the corporation to the fullest extent
permitted by applicable law against all expense, liability and loss, including
attorneys' fees, reasonably incurred or suffered by such person. However, the
Copenhagen's bylaws provide that, with respect to proceedings seeking to enforce
rights to indemnification, the corporation shall not indemnify any such person
seeking indemnification in connection with a proceeding initiated by the person,
unless the proceeding was authorized by the board of directors of the
corporation.

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

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

                                      II-8
<PAGE>   233

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

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. is a limited partnership 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>   234

     The articles of incorporation and bylaws of Network Cabling Services do not
contain provisions governing indemnification.

     Irwin Telecom Services, L.P.'s agreement of limited partnership provides
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. Sections 180.0850 to
180.0859 of the Wisconsin Corporate Statutes (the "Wisconsin Statute") require a

                                      II-10
<PAGE>   235

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.

ITEM 22. UNDERTAKINGS.

     (a) 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

                                      II-13
<PAGE>   238

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

     (b) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as a part of this
Registration Statement in reliance on Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be a part of this registration
statement as of the time it was declared effective.

     (c) For purposes of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

     (d) 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.

     (e) 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.

c/o Deutsche Bank Securities Inc.
31 West 52nd Street
New York, New York 10019

Ladies and Gentlemen:

                  Each of NATG Holdings, LLC, a Delaware limited liability
company ("NATG LLC"), and Orius Capital Corp., a Delaware corporation ("Orius
Capital" and together with NATG LLC, the "Issuers"), Orius Corp., a Florida
corporation ("Parent"), and the other guarantors party hereto (the "Subsidiary
Guarantors" and together with the Issuers, the "Subsidiaries") each hereby
confirms its agreement with you, as set forth below.

                  1. The Securities. Subject to the terms and conditions herein
contained, the Issuers propose to issue and sell to the several purchasers named
in Schedule 1 hereto (the "Initial Purchasers") $150,000,000 aggregate principal
amount of their 12 3/4% Senior Subordinated Notes due 2010 (the "Notes"). The
Notes are to be issued under an indenture (the "Indenture") to be dated as of
February 9, 2000 by and among Parent, the Issuers, the Subsidiary Guarantors and
United States Trust Company of New York, as trustee (the "Trustee").

                  The Notes will be guaranteed (the "Guarantees"), jointly and
severally, by Parent and the Subsidiary Guarantors (together, the "Guarantors"),
on a senior subordinated basis.

                  The Notes will be offered and sold to the Initial Purchasers
without being registered under the Securities Act of 1933, as amended (the
"Act"), in reliance on exemptions therefrom.

                  In connection with the sale of the Notes, Parent and the
Subsidiaries have prepared a preliminary offering memorandum dated January 17,
2000 (the "Preliminary Memorandum") and will prepare a final offering memorandum
dated February 4, 2000 (the "Final Memorandum"; the Preliminary Memorandum and
the Final Memorandum each herein being referred to as a "Memorandum") each
setting forth or including a description of the terms of the Notes, the terms of
the offering of the Notes, a description of Parent and the Subsidiaries

<PAGE>   2

and any material developments relating to Parent and the Subsidiaries occurring
after the date of the most recent historical financial statements included
therein.

                  Parent and the Subsidiaries understand that the Initial
Purchasers propose to make an offering of the Notes only on the terms and in the
manner set forth in the Memorandum and Section 8 hereof as soon as the Initial
Purchasers deem advisable after this Agreement has been executed and delivered,
to persons in the United States whom the Initial Purchasers reasonably believe
to be qualified institutional buyers ("Qualified Institutional Buyers" or
"QIBs") as defined in Rule 144A under the Act, as such rule may be amended from
time to time ("Rule 144A"), and outside the United States to certain persons in
reliance on Regulation S under the Act.

                  The Initial Purchasers and their direct and indirect
transferees will be entitled to the benefits of the Registration Rights
Agreement, substantially in the form attached hereto as Exhibit A (the
"Registration Rights Agreement"), to be dated the Closing Date (as defined in
Section 3 hereof) pursuant to which Parent and the Subsidiaries will agree,
among other things, to file a registration statement (the "Registration
Statement") with the Securities and Exchange Commission (the "Commission")
registering the Notes or the Exchange Notes (as defined in the Registration
Rights Agreement) under the Act.

                  2. Representations and Warranties. Parent and the Subsidiaries
represent and warrant, jointly and severally to, and agree with, each Initial
Purchaser on and as of the date hereof and the Closing Date that:

                  (a) Neither the Preliminary Memorandum as of the date thereof
         nor the Final Memorandum nor any amendment or supplement thereto as of
         the date thereof and, with respect to the Final Memorandum, at all
         times subsequent from the date thereof up to the Closing Date,
         contained or contains any untrue statement of a material fact or
         omitted or omits to state a material fact necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading, except that the representations and
         warranties set forth in this Section 2(a) do not apply to statements or
         omissions made in reliance upon and in conformity with information
         relating to any Initial Purchaser furnished to the Issuers in writing
         by Deutsche Bank Securities Inc. ("DB") expressly for use in the
         Preliminary Memorandum or the Final Memorandum or any amendment or
         supplement thereto, which information is set forth in Section 12
         hereof.

                  (b) As of the Closing Date, Parent will have the authorized,
         issued and outstanding capitalization set forth in the Final
         Memorandum, assuming the exercise of certain call options as described
         therein; all of the outstanding capital stock (which term, for the
         purposes of this Agreement, shall be deemed to include common stock,
         preferred stock, limited liability company membership interests,
         limited partnership interests, general partnership interests and all
         other similar equity interests) of Parent and the Subsidiaries has
         been, and as of the Closing Date will be, duly authorized and validly
         issued, fully paid and nonassessable and not issued in violation of any
         preemptive or

                                      -2-

         similar rights; Parent owns all of the capital stock of
         NATG LLC; NATG LLC owns, directly or indirectly all of the capital
         stock of Orius Capital and each Subsidiary Guarantor; each Subsidiary
         is listed on Schedule 2 hereto; all of the outstanding shares of
         capital stock of Parent and of each Subsidiary will be free and clear
         of all of all liens, encumbrances, equities and claims or restrictions
         on transferability or voting (other than (i) those imposed by the Act
         and the securities or "Blue Sky" laws of certain jurisdictions, (ii)
         those securing the obligations of Parent and the Subsidiaries under the
         Credit Agreement, dated as of December 15, 1999 (the "Senior Secured
         Credit Agreement") among Parent, NATG LLC, LISN, LLC, Bankers Trust
         Company as Agent, and the lenders from time to time party thereto, and
         (iii) such other liens, encumbrances, equities and claims as could not
         reasonably be expected to have a material adverse effect on the general
         affairs, management, existing business, condition (financial or
         otherwise), prospects or results of operations of the Parent and the
         Subsidiaries, taken as a whole (a "Material Adverse Effect")); except
         as set forth in the Final Memorandum, there are no (i) options,
         warrants or other rights to purchase from Parent or any Subsidiary,
         (ii) agreements or other obligations of Parent or any Subsidiary to
         issue or (iii) other rights to convert any obligation into, or exchange
         any securities for, capital stock of Parent or any of the Subsidiaries.
         Except for the Subsidiaries, the Company does not own, directly or
         indirectly, any capital stock or any other equity or long-term debt
         securities or have any equity interest in any firm, partnership, joint
         venture or other entity; provided, that LISN, Inc. owns a 49% equity
         interest in LB Price Communications, Inc., a Maryland corporation, and
         a 49% equity interest in DLS Wallace Corp., an Ohio corporation.

                  (c) Each of Parent and each Subsidiary has been duly
         incorporated or otherwise organized, is validly existing and is in good
         standing as a corporation, limited liability company or limited
         partnership, as the case may be, under the laws of its jurisdiction of
         organization, with all requisite corporate or other organizational
         power and authority to own its properties and carry on its business as
         now conducted and as proposed to be conducted, and as described in the
         Final Memorandum; Parent and each Subsidiary is duly qualified to do
         business in good standing as a foreign corporation, foreign limited
         liability company or foreign limited partnership, as the case may be,
         in every jurisdiction where the ownership or leasing of its existing
         properties and assets or the conduct of its existing business requires
         such qualification, except where the failure to be so qualified could
         not, individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect.

                  (d) Each of the Issuers has all requisite corporate or other
         organizational power and authority to execute, deliver and perform its
         obligations under the Notes, the Exchange Notes and the Private
         Exchange Notes (as defined in the Registration Rights Agreement). The
         Notes, when issued, will be in the form contemplated by the Indenture.
         The Notes, the Exchange Notes and the Private Exchange

                                      -3-

<PAGE>   4

         Notes will have each been duly and validly authorized by the Issuers
         and, when executed by the Issuers and authenticated by the Trustee in
         accordance with the provisions of the Indenture and, in the case of the
         Notes, when delivered to and paid for by the Initial Purchasers in
         accordance with the terms of this Agreement, and in the case of the
         Exchange Notes and the Private Exchange Notes, when delivered to and
         exchanged for the Notes in accordance with the terms of the
         Registration Rights Agreement, will constitute valid and legally
         binding obligations of each of the Issuers, entitled to the benefits of
         the Indenture and enforceable against each of the Issuers in accordance
         with their terms, except that the enforcement thereof may be subject to
         (i) bankruptcy, insolvency, reorganization, fraudulent conveyance or
         transfer, or other similar laws now or hereafter in effect relating to
         creditors' rights generally, and (ii) general principles of equity and
         the discretion of the court before which any proceeding therefore may
         be brought (regardless of whether such enforcement is considered in a
         proceeding in equity or at law).

                  (e) Each of Parent and each Subsidiary has all requisite
         corporate or other organizational power and authority to execute,
         deliver and perform its obligations under the Indenture. When executed
         by Parent and each Subsidiary, the Indenture will meet the requirements
         as of the date hereof for qualification under the Trust Indenture Act
         of 1939, as amended (the "TIA"). The Indenture has been duly and
         validly authorized by Parent and each Subsidiary and, when executed and
         delivered by Parent and each Subsidiary (assuming the due
         authorization, execution and delivery by the Trustee), will constitute
         a valid and legally binding agreement of each of Parent and each
         Subsidiary, enforceable against Parent and each Subsidiary in
         accordance with its terms, except that the enforcement thereof may be
         subject to (i) bankruptcy, insolvency, reorganization, fraudulent
         conveyance or transfer, or other similar laws now or hereafter in
         effect relating to creditors' rights generally and (ii) general
         principles of equity and the discretion of the court before which any
         proceeding therefor may be brought (regardless of whether such
         enforcement is considered in a proceeding in equity or at law).

                  (f) Each of Parent and each Subsidiary has all requisite
         corporate or other organizational power and authority to execute,
         deliver and perform its obligations under the Registration Rights
         Agreement. The Registration Rights Agreement has been duly and validly
         authorized by Parent and each Subsidiary and, when executed and
         delivered by Parent and each Subsidiary (assuming the due
         authorization, execution and delivery by the other parties thereto),
         will constitute a valid and legally binding agreement of Parent and
         each Subsidiary, enforceable against Parent and each Subsidiary in
         accordance with its terms, except that the enforcement thereof may be
         subject to (i) bankruptcy, insolvency, reorganization, fraudulent
         conveyance or transfer, or other similar laws now or hereafter in
         effect relating to creditors' rights generally and (ii) general
         principles of equity and the discretion of the court before which any
         proceeding therefor may be brought (regardless of whether such
         enforcement is considered in a proceeding in equity or at law).

                  (g) Each of Parent and each Subsidiary has all requisite
         corporate or other organizational power and authority to execute,
         deliver and perform its obligations under this Agreement and to
         consummate the transactions contemplated hereby. This Agreement and the
         consummation by Parent and each Subsidiary of the transactions
         contemplated hereby have been duly and validly authorized by Parent and
         each

         Subsidiary This Agreement has been duly and validly executed and
         delivered by Parent and each Subsidiary.

                  (h) Each Guarantor has all requisite corporate power and
         authority to execute, deliver and perform its obligations under its
         Guarantee, and its guarantees of the Exchange Notes and the Private
         Exchange Notes. Each such Guarantee and each such guarantee of the
         Exchange Notes and Private Exchange Notes has been and validly
         authorized and when executed and delivered by the applicable Guarantor
         will constitute a valid and legally binding agreement of such Guarantor
         enforceable against such Guarantor in accordance with its terms, except
         that the enforcement thereof may be subject to (i) bankruptcy,
         insolvency, reorganization, fraudulent conveyance or transfer, or other
         similar laws now or hereafter in effect relating to creditors' rights
         generally and (ii) general principles of equity and the discretion of
         the court before which any proceeding therefor may be brought
         (regardless of whether such enforcement is considered in a proceeding
         in equity or at law).

                  (i) No consent, approval, authorization or order of any court
         or governmental agency or body, or third party is required for the
         performance of this Agreement, the Registration Rights Agreement or the
         Indenture by Parent or any Subsidiary or the consummation by Parent or
         any Subsidiary of the transactions contemplated hereby, thereby or by
         the Final Memorandum except (i) such as have been obtained, (ii) such
         as may be required under (A) state securities or "Blue Sky" laws in
         connection with the purchase and resale of the Notes by the Initial
         Purchasers, (B) the Act with respect to the registration of the
         Exchange Notes and the Private Exchange Notes pursuant to the
         Registration Rights Agreement, or (C) the Trust Indenture Act of 1939,
         as amended (the "TIA"), with respect to the registration of the
         Exchange Notes and the Private Exchange Notes pursuant to the
         Registration Rights Agreement, and (iii) such that could not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect. None of Parent or any Subsidiary is (i) in
         violation of its certificate of incorporation or bylaws (or similar
         organizational document), (ii) in breach or violation of any statute,
         judgment, decree, order, rule or regulation applicable to any of them
         or any of their respective properties, business or assets, except for
         any such breach or violation which could not, individually or in the
         aggregate, reasonably be expected to have a Material Adverse Effect, or
         (iii) in breach of or in default under (nor has any event occurred
         which, with notice or passage of time or both, would constitute a
         default under) or in violation of any of the terms or provisions of any
         indenture, mortgage, deed of trust, loan agreement, note, lease,
         license, franchise agreement, permit, certificate, contract or other
         agreement or instrument to which any of them is a party or to which any
         of them or their respective properties, business or assets is subject
         (collectively, "Contracts") except where such breach, default or
         violation could not, individually or in the aggregate, reasonably be
         expected to have a Material Adverse Effect.

                  (j) The execution, delivery and performance by Parent and each
         Subsidiary of this Agreement, the Indenture and the Registration Rights
         Agreement and the consummation by Parent and each Subsidiary of the
         transactions contemplated hereby and thereby

         the Initial Purchasers) will not conflict with or constitute or result
         in a breach of or a default under (or an event which with notice or
         passage of time or both would constitute a default under) or violation
         of any of (i) the terms or provisions of any Contract, except for any
         such conflict, breach, violation, default or event which could not,

         other pro forma financial information included in the Preliminary
         Memorandum and the Final Memorandum are reasonable and the adjustments
         used therein are appropriate to give effect to the transactions or
         circumstances referred to therein.

                  (m) There is not pending or, to the knowledge of Parent or any
         Subsidiary, threatened any action, suit, proceeding, inquiry or
         investigation to which any of Parent or any Subsidiary is a party, or
         to which the property or assets of any of Parent or any Subsidiary are
         subject, before or brought by any court, arbitrator or governmental
         agency or body which, if determined adversely to Parent or any
         Subsidiary could, individually or in the aggregate, reasonably be
         expected to have a Material Adverse Effect or which seeks to restrain,
         enjoin, prevent the consummation of or otherwise challenge the issuance
         or sale of the Notes to be sold hereunder, the issuance of the
         Guarantees, the use of any Memorandum in any jurisdiction, or the
         consummation of the other transactions described in the Final
         Memorandum.

                  (n) Each of Parent and each Subsidiary owns or possesses
         adequate licenses or other rights to use all material patents,
         trademarks, service marks, trade names, copyrights and know-how
         necessary to conduct the businesses now or proposed to be operated by
         it as described in the Final Memorandum, except as could not reasonably
         be expected to have a Material Adverse Effect, and none of Parent or
         the Subsidiaries has received any notice of infringement of or conflict
         with (or knows of any such infringement of or conflict with) asserted
         rights of others with respect to any patents, trademarks, service
         marks, trade names, copyrights or know-how which, if such assertion of
         infringement or conflict were sustained, could, individually or in the
         aggregate, reasonably be expected to have a Material Adverse Effect.

                  (o) Parent and each Subsidiary possesses all licenses,
         permits, certificates, consents, orders, approvals and other
         authorizations from, and has made all declarations and filings with,
         all federal, state, local and other governmental authorities, all
         self-regulatory organizations and all courts and other tribunals,
         presently required or necessary to own or lease, as the case may be,
         and to operate its respective properties and to carry on its respective
         businesses as now or proposed to be conducted as set forth in the Final
         Memorandum (collectively, the "Permits"), except as could not
         reasonably be expected to have a Material Adverse Effect; Parent and
         each Subsidiary has fulfilled and performed all of its obligations with
         respect to such Permits and no event has occurred which allows, or
         after notice or lapse of time would allow, revocation or termination
         thereof or results in any other material impairment of the rights of
         the holder of any such Permit, except where the failure to perform such
         obligation could not, individually or in the aggregate, reasonably be
         expected to have a Material Adverse Effect; and none of

                                      -7-
<PAGE>   8

         Parent or the Subsidiaries has received any written notice of any
         proceeding relating to revocation or modification of any such Permit,
         except where such revocation or modification could not, individually or
         in the aggregate, reasonably be expected to have a Material Adverse
         Effect.

                  (p) Since the date of the most recent financial statements
         appearing in the Final Memorandum, except as described or contemplated
         in the Final Memorandum, (i) none of Parent or the Subsidiaries has
         incurred any liabilities or obligations, direct or contingent, or
         entered into or agreed to enter into any transactions or contracts
         (written or oral) not in the ordinary course of business which
         liabilities, obligations, transactions or contracts would, individually
         or in the aggregate, be material to the general affairs, management,
         business, condition (financial or otherwise), prospects or results of
         operations of Parent and the Subsidiaries, taken as a whole (a
         "Material Change"), (ii) none of Parent or any Subsidiary has purchased
         any of its outstanding capital stock, nor declared, paid or otherwise
         made any dividend or distribution of any kind on its capital stock
         (other than with respect to a Subsidiary, the purchase of, or dividend
         or distribution on, capital stock owned by NATG LLC), and (iii) there
         shall not have been any change in the capital stock, or long-term
         indebtedness of Parent or any Subsidiary which would, individually or
         in the aggregate, constitute a Material Change.

                  (q) Each of Parent and each Subsidiary has filed all necessary
         federal, state, local and foreign income and franchise tax returns,
         except where the failure to file such returns could not, individually
         or in the aggregate, reasonably be expected to have a Material Adverse
         Effect, and has paid all taxes shown as due thereon; other than tax
         deficiencies which Parent or any Subsidiary is contesting in good faith
         and for which Parent or such Subsidiary has provided adequate reserves,
         there is no tax deficiency that has been asserted against any of Parent
         or any Subsidiary that could, individually or in the aggregate,
         reasonably be expected to have a Material Adverse Effect.

                  (r) Neither Parent nor any Subsidiary owns any "margin
         securities" as that term is defined in Regulation U of the Board of
         Governors of the Federal Reserve System (the "Federal Reserve Board"),
         and none of the proceeds of the sale of the Notes will be used,
         directly or indirectly, for the purpose of purchasing or carrying any
         margin security, for the purpose of reducing or retiring any
         indebtedness which was originally incurred to purchase or carry any
         margin security or for any other purpose which might cause any of the
         Notes to be considered a "purpose credit" within the meanings of
         Regulation T, U or X of the Federal Reserve Board. Without limiting the
         foregoing, none of Parent, the Subsidiaries or any agent acting on
         behalf of any of them has taken or will take any action that might
         cause this Agreement or the sale of the Notes to violate Regulation T,
         U or X of the Federal Reserve Board, in each case as in effect, or as
         the same may hereafter be in effect, on the Closing Date.

                  (s) The statistical and market-related data included in the
         Final Memorandum are based on or derived from sources which Parent and
         the Subsidiaries believe to be reliable and accurate.

         title to all real property and good title to all personal property
         described in the Final Memorandum as being owned by it and good and
         marketable title to a leasehold estate in the real and personal
         property described in the Final Memorandum as being leased by it free
         and clear of all liens, charges, encumbrances or restrictions (other
         than those arising in connection with the Senior Secured Credit
         Agreement), except to the extent the failure to have such title or the
         existence of such liens, charges, encumbrances or restrictions could
         not, individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect. All leases, contracts and agreements to which
         any of Parent or any Subsidiary is a party or by which any of them is
         bound are valid and enforceable against Parent or such Subsidiary, and,
         to the knowledge of Parent and each Subsidiary, are valid and
         enforceable against the other party or parties thereto and are in full
         force and effect with only such exceptions as could not, individually
         or in the aggregate, reasonably be expected to have a Material Adverse
         Effect.

                  (u) There are no legal or governmental proceedings involving
         Parent or any Subsidiary or any of their respective properties or
         assets known to any of them which would be required to be described in
         a prospectus pursuant to the Act that are not described in the Final
         Memorandum, and to the knowledge of Parent and the Subsidiaries no such
         proceedings are threatened or contemplated by governmental authorities
         or threatened by others, nor are there any material contracts or other
         documents which would be required to be described in a prospectus
         pursuant to the Act that are not described in the Final Memorandum.

                  (v) Except as could not, individually or in the aggregate,

         Parent and each Subsidiary is in compliance with applicable
         Environmental Laws (as defined below), (B) each of Parent and each
         Subsidiary has made all filings and provided all notices required under

         them is in full force and effect, (C) there is no civil, criminal or
         administrative action, suit, demand, claim, hearing, notice of
         violation, investigation, proceeding, notice or demand letter or

         Subsidiary, threatened against Parent or any Subsidiary under any
         Environmental Law, (D) no lien, charge, encumbrance or restriction has
         been recorded under any Environmental Law with respect to any assets,
         facility or property owned, operated, leased or controlled by Parent or
         the Subsidiaries, (E) none of Parent or the Subsidiaries has received
         notice that it has been identified as a potentially responsible party
         under the Comprehensive Environmental Response, Compensation and
         Liability Act of 1980, as amended ("CERCLA") or any comparable state
         law and (F) no property or facility of Parent or the Subsidiaries is
         (i) listed or proposed for listing on the National Priorities List
         under CERCLA or (ii) listed in the Comprehensive Environmental
         Response, Compensation, Liability Information System List promulgated
         pursuant to CERCLA, or on any comparable list maintained by any state
         or local governmental authority.

         conduct of its business and the value of its properties.

                  (y) None of Parent or the Subsidiaries has any liability for
         any prohibited transaction (within the meaning of Section 4975(c) of

         of ERISA) or any complete or partial withdrawal liability (within the
         meaning of Section 4201 of ERISA) with respect to any pension, profit
         sharing or other plan which is subject to ERISA, to which Parent or any
         Subsidiary makes or ever has made a contribution and in which any
         employee of Parent or any Subsidiary is or has ever been a participant.
         With respect to such plans, each of Parent and each Subsidiary is in
         compliance in all respects with all applicable provisions of ERISA, or,
         if not in compliance, any such failure or failures to comply could not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect.

                  (z) Parent and each Subsidiary (i) makes and keeps books and
         records that are accurate in all material respects and (ii) maintains
         internal accounting controls which provide reasonable assurance that
         (A) transactions are executed in accordance with management's

         preparation of its financial statements and to maintain accountability
         for its assets, (C) access to its assets is permitted only in
         accordance with management's authorization and (D) the reported
         accountability for its assets is compared with existing assets at

         Exchange Act).

                  (ii) None of Parent or the Subsidiaries, or any person acting

         of automated, computerized or software systems) that are used in the
         business of Parent or the Subsidiaries are capable of accurately
         processing, calculating, manipulating, storing and exchanging date/time
         data from, into, and between the twentieth and twenty-first centuries,
         including, without limitation, the years 1999 and 2000 and any leap
         year calculations, except where the failure could not reasonably be
         expected to have a Material Adverse Effect. Parent and the Subsidiaries
         have experienced no Material Adverse Effect as a result of the
         changeover to the year 2000.

                  (nn) None of Parent or the Subsidiaries is a party to any
         contract, agreement or understanding with any person other than this
         agreement that would give rise to a valid claim against the Issuers or
         the Initial Purchasers for a brokerage commission, finder's fee or like
         payment solely as a result of the offering and sale of the Notes.

                  (oo)  The Notes satisfy the eligibility requirements of Rule
         144A(d)(3) under the Act.

                  3. Purchase, Sale and Delivery of the Notes. On the basis of
the representations, warranties, agreements and covenants herein contained and
subject to the terms and conditions herein set forth, the Issuers agree to issue
and sell to the Initial Purchasers, and each Initial Purchaser, acting severally
and not jointly, agrees to purchase from the Issuers the principal amount of
Notes set forth opposite its name on Schedule 1 hereto at 97% of their principal
amount. One or more certificates in definitive form for the Notes that each
Initial Purchaser has agreed to purchase hereunder, and in such denomination or
denominations and registered in such name or names as each Initial Purchaser
requests upon notice to the Issuers, at least 36 hours prior to the Closing Date
shall be delivered by or on behalf of the Issuers to the Initial Purchasers,
against payment by or on behalf of the Initial Purchasers of the purchase price
therefor by wire transfer (same day funds) to such account or accounts as the
Issuers shall specify prior to the Closing Date, or by such means as the parties
hereto shall agree prior to the Closing Date. Such delivery of and payment for
the Notes shall be made at the offices of White & Case LLP, 1155 Avenue of the
Americas, New York, New York 10036 at 10:00 A.M., New York time, on February 9,
2000, or at such other place, time or date as the Initial Purchasers, on the one
hand, and the Issuers, on the other hand, may agree upon, such time and date of
delivery against payment being herein referred to as the "Closing Date." The
Issuers will make such certificate or certificates for the Notes available for
inspection and packaging by each Initial Purchaser at the offices of DB in New
York, New York, or at such other place as the Initial Purchasers may designate,
at least 24 hours prior to the Closing Date.

                  4. Offering by the Initial Purchasers. The Initial Purchasers
propose to make an offering of the Notes at the price and upon the terms set
forth in the Final Memorandum, as soon as practicable after this Agreement is
entered into and as in the judgment of the Initial Purchasers is advisable.

                  5. Covenants of the Company. Parent and each of the
Subsidiaries, jointly and severally, covenant and agree with each Initial
Purchaser that:

                  (a) Parent and the Subsidiaries will not amend or supplement
         the Final Memorandum or any amendment or supplement thereto of which
         each Initial Purchaser shall not previously have been advised and
         furnished a copy for a reasonable period of time prior to the proposed
         amendment or supplement and as to which each Initial Purchaser shall
         not have consented, which consent shall not be unreasonably withheld.

                  (b) Parent and the Subsidiaries will promptly, upon the
         written request of the Initial Purchasers or counsel for the Initial
         Purchasers, make any amendments or supplements to the Preliminary
         Memorandum or the Final Memorandum that may be necessary or advisable
         in connection with the resale of the Notes by the Initial Purchasers;
         provided, that Parent shall have consented to such amendment or
         supplement, such consent not to be unreasonably withheld.

                  (c) Parent and the Subsidiaries will cooperate with each
         Initial Purchaser in arranging for the qualification of the Notes for
         offering and sale under the securities or "Blue Sky" laws of such
         jurisdictions as such Initial Purchaser may reasonably designate

                                      -13-

<PAGE>   14

         and will continue such qualifications in effect for as long as may be
         necessary to complete the distribution of the Notes; provided, however,
         that in connection therewith, Parent and the Subsidiaries shall not be
         required to qualify as foreign corporations or to execute general
         consents to service of process in any jurisdiction or subject
         themselves to taxation in excess of a nominal dollar amount in any such
         jurisdiction where they are not then so subject.

                  (d) If, at any time prior to the completion of the
         distribution by the Initial Purchasers of the Notes or the Private
         Exchange Notes, any event occurs or information becomes known as a
         result of which the Final Memorandum as then amended or supplemented
         would include any untrue statement of a material fact, or omit to state
         a material fact necessary to make the statements therein, in the light
         of the circumstances under which they were made, not misleading, or if
         for any other reason it is necessary to amend or supplement the Final
         Memorandum to comply with applicable law, Parent and the Subsidiaries
         will promptly notify each Initial Purchaser thereof and will prepare,
         at the expense of Parent and the Subsidiaries, an amendment or
         supplement to the Final Memorandum that corrects such statement or
         omission or effects such compliance.

                  (e) Parent and the Subsidiaries will, without charge, provide
         to each Initial Purchaser and to counsel for the Initial Purchasers as
         many copies of the Preliminary Memorandum and the Final Memorandum or
         any amendment or supplement thereto as the Initial Purchasers may
         reasonably request; provided, that if such request is made after the
         original printing of the Final Memorandum or any amendment or
         supplement thereto, such copies need not be reprinted at the expense of
         Parent and the Subsidiaries.

                  (f) Parent and the Subsidiaries will apply the net proceeds
         from the sale of the Notes as set forth under the caption "Use of
         Proceeds" in the Final Memorandum.

                  (g) Until the date that no Notes are outstanding under the
         Indenture, Parent and the Subsidiaries will furnish to each Initial
         Purchaser, upon its written request, copies of all reports and other
         communications (financial or otherwise) furnished by Parent or any
         Subsidiary to the Trustee, or the holders of the Notes in such number
         of copies as may be reasonably requested by each Initial Purchaser and,
         as soon as available, copies of any reports or financial statements
         furnished to or filed by Parent or any Subsidiary with the Commission
         or any national securities exchange on which any class of securities of
         the Parent or any Subsidiary may be listed in such number of copies as
         may be reasonably requested by the Initial Purchasers.

                  (h) None of the Issuers or any of their affiliates has sold,
         offered for sale or solicited, or will sell, offer for sale or solicit
         offers to buy or otherwise negotiate in respect of any "security" (as
         defined in the Act) which could be integrated with the sale of the
         Notes in a manner which would require the registration under the Act of
         the Notes.

                  (i) None of Parent, the Subsidiaries or any of their
         Affiliates will engage in any form of "general solicitation" or
         "general advertising" (as those terms are used in Regulation D under
         the Act) in connection with the offering of the Notes or in any

                                      -14-
<PAGE>   15


         manner involving a public offering of the Notes within the meaning of
         Section 4(2) of the Act.

                  (j) For so long as any of the Notes remain outstanding, Parent
         and the Subsidiaries will make available, upon request, to any seller
         of such Notes the information specified in Rule 144A(d)(4) under the
         Act.

                  (k) Parent and the Subsidiaries will use their respective
         reasonable best efforts to permit (i) the Notes to be designated PORTAL
         securities in accordance with the rules and regulations adopted by the
         NASD relating to trading in the NASD's Portal Market (the "Portal
         Market") and (ii) the Notes to be eligible for clearance and settlement
         through The Depository Trust Company.

                  (l) None of the Issuers or any of their affiliates nor any
         person acting on its or their behalf will engage, in any directed
         selling efforts (as that term is defined in Regulation S) with respect
         to the Notes, and the Issuers will comply, and will cause their
         affiliates and each person acting on its or their behalf to comply,
         with the offering restrictions requirements of Regulation S.

                  (m) Parent and each Subsidiary agrees that for a period of 180
         days from the date of the Final Memorandum, it will not offer for sale,
         sell, contract to sell or otherwise dispose of, directly or indirectly,
         or file a registration statement for, or announce any offer, sale,
         contract for sale of or other disposition of any debt securities issued
         or guaranteed by Parent or any of the Subsidiaries (other than the
         Notes) without the prior written consent of the Initial Purchasers.

                  (n) During the period from the Closing date until two years
         after the Closing Date, without the prior written consent of the
         Initial Purchasers, each of Parent and each Subsidiary agrees not to
         resell, and to use its reasonable best efforts to prevent any of its
         Affiliates from reselling, any of the Notes that have been reacquired
         by them, except for Notes purchased by the Issuers or any of their
         Affiliates and resold in a transaction registered under the Act.

                  (o) In connection with the offering of the Notes, until DB on
         behalf of the Initial Purchasers shall have notified the Issuers of the
         completion of the resale of the Notes, each Issuer agrees not to, and
         to cause its affiliated purchasers (as defined in Regulation M under
         the Exchange Act) not to, either alone or with one or more other
         persons, bid for or purchase, for any account in which it or any of its
         affiliated purchasers has a beneficial interest, any Notes, or attempt
         to induce any person to purchase any Notes; and not to, and to cause
         its affiliated purchasers not to, make bids or purchase for the purpose
         of creating actual, or apparent active trading in or of raising the
         price of the Notes.

                  (p) Prior to the Closing Date, Parent and the Subsidiaries
         agree not to issue any press release or other communication directly or
         indirectly or hold any press conference with respect to Parent or the
         Subsidiaries, their condition, financial or otherwise, or earnings,
         business affairs or business prospects (except for routine oral
         marketing

                                      -15-
<PAGE>   16



         communications in the ordinary course of business and consistent with
         the past practices of Parent and the Subsidiaries and of which the
         Initial Purchasers are notified), without the prior written consent of
         the Initial Purchasers, unless in the judgment of the Issuers and
         their counsel, and after notification to the Initial Purchasers, such
         press release or communication is required by law.

                  6. Expenses. Parent and the Subsidiaries, jointly and
severally, agree to pay all costs and expenses incident to the performance of
their obligations under this Agreement, whether or not the transactions
contemplated herein are consummated or this Agreement is terminated pursuant to
Section 11 hereof, including all costs and expenses incident to (i) the costs of
printing the Memorandum and any amendment or supplement thereto, and preparing
any "Blue Sky" memoranda, (ii) all arrangements relating to the delivery to each
Initial Purchaser of copies of the Memorandum and any amendment or supplement
thereto, (iii) the fees and disbursements of counsel, accountants and any other
experts or advisors retained by Parent or any Subsidiary, (iv) preparation
(including printing), issuance and delivery to each Initial Purchaser of the
Notes, (v) the qualification of the Notes under state securities and "Blue Sky"
laws, including filing fees and reasonable fees and disbursements of counsel for
the Initial Purchasers relating thereto, (vi) costs and expenses in connection
with any the "roadshow" and any other meetings with prospective investors in the
Notes, (vii) fees and expenses of the Trustee including reasonable fees and
expenses of counsel, (viii) all expenses and listing fees incurred in connection
with the application for quotation of the Notes on the PORTAL Market and (ix)
any fees charged by investment rating agencies for the rating of the Notes. If
the sale of the Notes provided for herein is not consummated because any
condition to the obligations of any Initial Purchaser set forth in Section 7
hereof is not satisfied, because this Agreement is terminated or because of any
failure, refusal or inability on the part of any of Parent and the Subsidiaries
to perform all obligations and satisfy all conditions on their part to be
performed or satisfied hereunder (other than solely by reason of a default by
the Initial Purchasers of their obligations hereunder after all conditions
hereunder have been satisfied in accordance herewith), the Parent and the
Subsidiaries jointly and severally agree to promptly reimburse each Initial
Purchaser upon demand for all out-of-pocket expenses (including all reasonable
fees, disbursements and charges of White & Case LLP, counsel for the Initial
Purchasers) that shall have been reasonably incurred by each Initial Purchaser
in connection with the proposed purchase and sale of the Notes. Except as
provided in this Section 6, the Initial Purchasers shall be responsible for
their own fees and expenses, including the fees and expenses of their counsel.

                  7. Conditions of the Initial Purchaser's Obligations. The
obligation of each Initial Purchaser to purchase and pay for the Notes shall be
subject to the satisfaction or waiver of the following conditions on or prior to
the Closing Date:

                  (a) The Final Memorandum (and any amendments or supplements
         thereto) shall have been printed and copies distributed to the Initial
         Purchasers as promptly as practicable on or following the date of this
         Agreement or at such other date and time as to which the Initial
         Purchasers may agree; and no stop order suspending the sale of the
         Notes in any jurisdiction shall have been issued and no proceedings for
         the purpose shall have been commenced or shall be pending or
         threatened.

         disclosed to Parent or any Subsidiary on or prior to the Closing Date
         that the Final Memorandum or any amendment or supplement thereto
         contains an untrue statement of a fact which, in the opinion of counsel
         for the Initial Purchasers, is material or omits to state any fact
         which, in the opinion of such counsel is material and is required to be
         stated therein or is necessary to make the statements therein not
         misleading.

                  (c) All corporate proceedings and other legal matters incident

         subsequent to the date of the most recent financial statements in such
         Final Memorandum, there shall have been no event or development that,

         Subsidiary from their respective states of organization.

                  (i) The sale of the Notes hereunder shall not be enjoined
         (temporarily or permanently) on the Closing Date.

                  (j) Subsequent to the date of the most recent financial
         statements in the Final Memorandum (exclusive of any amendment or
         supplement thereto after the date hereof), the conduct of the business
         and operations of Parent and the Subsidiaries shall not have been
         interfered with by, fire, flood, hurricane, accident or other calamity
         (whether or not insured) or from any strike, labor dispute, slow down
         or work stoppage, or by any court or governmental action, order or
         decree, and, except as otherwise stated therein, the properties of
         Parent or any of the Subsidiaries shall not have sustained any loss or
         damage (whether or not insured) as a result of any such occurrence,
         except any such interference, loss or damage which could not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect.

                  (k) There shall not have occurred any invalidation of Rule
         144A under the Act by any court or any withdrawal or proposed
         withdrawal of any rule or regulation under the Act or the Exchange Act
         by the Commission or any amendment or proposed amendment thereof by the
         Commission which in the judgment of the Initial Purchasers would
         materially impair the ability of the Initial Purchasers to purchase,
         hold or effect resales of the Notes contemplated hereby.

                  (l) The Initial Purchasers shall have received a certificate
         from Parent and each Subsidiary, dated the Closing Date, signed by the

         secretary or assistant secretary of each such entity to the effect
         that:

                           (i) Such executive officers have carefully examined
                  the Final Memorandum, and the Final Memorandum, as of its
                  date, did not include any untrue statement of a material fact
                  and did not omit to state a material fact required to be
                  stated therein or necessary in order to make the statements
                  therein, in the light of the circumstances under which they
                  were made, not misleading, and since the date of the Final
                  Memorandum, no event has occurred which should have been set
                  forth in a supplement or amendment to the Final Memorandum so
                  that the Final Memorandum (as so amended or supplemented)
                  would not include any untrue statement of a material fact and
                  would not omit to state a material fact required to be stated
                  therein or necessary in order to make the statements therein,
                  in light of the circumstances under which they were made, not
                  misleading.

                           (ii) The representations and warranties of such
                  entity contained in this Agreement are true and correct as of
                  the Closing Date, and entity has performed in all material
                  respects all covenants and agreements and satisfied in all
                  material respects all conditions on its part to be performed
                  or satisfied hereunder at or prior to the Closing Date.

                  or supplement thereto after the date hereof), except as
                  described in the Final Memorandum, to their knowledge after
                  due inquiry, no event or development has occurred, no
                  information has become known nor does any condition exist
                  that, individually or in the aggregate, has had or could
                  reasonably be expected to have a Material Adverse Effect.

                           (iv) No proceeding is pending or contemplated for the
                  liquidation or dissolution of such entity or threatening its
                  existence.

                  Each such certificate shall also have attached copies of (i)
         all resolutions of the Board of Directors of such entity authorizing
         the transactions contemplated by this Agreement, including, without
         limitation, approving the offering of the Notes, the execution,
         performance and delivery of this Agreement, the Indenture and the
         Registration Rights Agreements, (ii) the certificate of incorporation
         and by-laws or analogous organizational documents of such entity, and
         (iii) the names, offices and specimen signatures of each officer of
         such entity that will execute any document delivered in connection with
         the transactions contemplated by this Agreement. For the purposes of
         the certificate contemplated by this Section 7(1), the following shall
         be deemed to be "executive officers" of a particular entity: its
         Chairman of the Board, Vice Chairman of the Board, President, Chief
         Executive Officer, Chief Operating Officer, Chief Financial Officer or
         Executive Vice President.

                  (m) On the Closing Date, the Initial Purchasers shall have
         received the Registration Rights Agreement duly executed by Parent and
         each Subsidiary and such agreement shall be in full force and effect at
         all times from and after the Closing Date.

                  (n) The Indenture shall have been duly executed and delivered
         by Parent, the Subsidiaries and the Trustee, and the Notes shall have
         been duly executed and delivered by Parent and the Subsidiaries and
         duly authenticated by the Trustee.

                  (o) The Notes shall have been approved by the NASD for trading
         in the PORTAL Market.

         On or before the Closing Date, the Initial Purchasers and counsel for
the Initial Purchasers shall have received such further documents, opinions,
certificates, letters and schedules or instruments relating to the business,
corporate, legal and financial affairs of Parent and the Subsidiaries as they
shall have heretofore reasonably requested from the Issuers.

                                      -19-

<PAGE>   20

         All such documents, opinions, certificates, letters, schedules or
instruments delivered pursuant to this Agreement will comply with the provisions
hereof only if they are reasonably satisfactory in all material respects to the
Initial Purchasers and counsel for the Initial Purchasers. The Issuers shall
furnish to the Initial Purchasers such conformed copies of such documents,
opinions, certificates, letters, schedules and instruments in such quantities as
the Initial Purchasers shall reasonably request.

                  8. Offering of Notes; Restrictions on Transfer. Each Initial
Purchaser agrees with the Issuers (as to itself only) that (i) it has not and
will not solicit offers for, or offer or sell, the Notes by any form of general
solicitation or general advertising (as those terms are used in Regulation D
under the Act) or in any manner involving a public offering within the meaning
of Section 4(2) of the Act; and (ii) it has and will solicit offers for the
Notes only from, and will offer the Notes only to (A) in the case of offers
inside the United States, persons whom such Initial Purchaser reasonably
believes to be QIBs or, if any such person is buying for one or more
institutional accounts for which such person is acting as fiduciary or agent,
only when such person has represented to such Initial Purchaser that each such
account is a QIB, to whom notice has been given that such sale or delivery is
being made in reliance on Rule 144A, and (B) in the case of offers outside the
United States, to persons other than U.S. persons ("foreign purchasers," which
term shall include dealers or other professional fiduciaries in the United
States acting on a discretionary basis for foreign beneficial owners (other than
an estate or trust)); provided, however, that, in the case of this clause (B),
in purchasing such Notes such persons are deemed to have represented and agreed
as provided under the caption "Notice to Investors" contained in the Final
Memorandum.
                  Each Initial Purchaser represents and warrants (as to itself
only) with respect to offers and sales outside the United States that (i) it has
and will comply with all applicable laws and regulations in each jurisdiction in
which it acquires, offers, sells or delivers Notes or has in its possession or
distributes any Memorandum or any such other material, in all cases at its own
expense; (ii) the Notes have not been and will not be offered or sold within the
United States or to, or for the account or benefit of, U.S. persons except in
accordance with Regulation S under the Act or pursuant to an exemption from the
registration requirements of the Act; (iii) (A) it has not offered or sold, and,
prior to the expiration of the period of six months from the Closing Date, will
not offer or sell any Notes to persons in the United Kingdom, except to those
persons whose ordinary activities involve them in acquiring, holding, managing
or disposing of investments (as principal or agent) for the purpose of their
businesses or otherwise in circumstances which have not resulted and will not
result in an offer to the public in the United Kingdom within the meaning of the
Public Offers of Securities Regulations 1995, (B) it has complied and will
comply with all applicable provisions of the Financial Services Act of 1986,
with respect to anything done by it in relation to the Notes in, from or
otherwise involving the United Kingdom, and (C) it has only issued or passed on
and will only issue or pass on in the United Kingdom any document received by it
in connection with the issue of the Notes to a person who is of a kind described
in Article 11(3) of the Financial Services Act 1986 (Investment Advertisements)
(Exemptions) Order 1996, as amended, or is a person to whom the document may
otherwise lawfully be issued or passed on; and (iv) it has offered the Notes and
will offer and sell the Notes (A) as part of its distribution at any time and
(B) otherwise until 40 days after


                                      -20-

<PAGE>   21

the later of the commencement of the offering and the Closing Date, only in
accordance with Rule 903 of Regulation S and, accordingly, neither it nor any
persons acting on its behalf have engaged or will engage in any directed selling
efforts (within the meaning of Regulation S) with respect to the Notes, and any
such persons have complied and will comply with the offering restrictions
requirement of Regulation S.

                  Terms used in this Section 8 and not defined in this Agreement
have the meanings given to them in Regulation S.

                  9. Indemnification and Contribution. (a) Parent and the
Subsidiaries jointly and severally agree to indemnify and hold harmless each
Initial Purchaser and each person, if any, who controls any Initial Purchaser
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
against any losses, claims, damages or liabilities to which any Initial
Purchaser or such controlling person may become subject under the Act, the
Exchange Act or otherwise, insofar as any such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon:

                    (i) any untrue statement or alleged untrue statement made by
         Parent or any Subsidiary in Section 2 hereof;

                   (ii) any untrue statement or alleged untrue statement of any
         material fact contained in any Memorandum or any amendment or
         supplement thereto; or

                  (iii) the omission or alleged omission to state, in any
         Memorandum or any amendment or supplement thereto, a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading,

and will reimburse, as incurred, the Initial Purchasers and each such
controlling person for any legal or other expenses incurred by the Initial
Purchasers or such controlling person in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action; provided, however, Parent and the
Subsidiaries will not be liable in any such case to the extent that any such
loss, claim, damage, or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
any Memorandum or any amendment or supplement thereto in reliance upon and in
conformity with written information concerning the Initial Purchasers furnished
to the Company by the Initial Purchasers through DB specifically for use
therein, which information is set forth in Section 12. The indemnity provided
for in this Section 9 will be in addition to any liability that parent or a
Subsidiary may otherwise have to the indemnified parties. None of Parent or any
Subsidiary shall be liable under this Section 9 for any settlement of any claim
or action effected without its prior written consent, which shall not be
unreasonably withheld.

                  (b) Each Initial Purchaser, severally and not jointly, agrees
to indemnify and hold harmless Parent and each Subsidiary, its directors, its
officers and each person, if any, who controls Parent or any Subsidiary within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act against
any losses, claims, damages or liabilities to which the Parent, a


                                      -21-

<PAGE>   22

Subsidiary or any such director, officer or controlling person may become
subject under the Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained in any Memorandum or any amendment or supplement
thereto, or (ii) the omission or the alleged omission to state therein a
material fact required to be stated in any Memorandum or any amendment or
supplement thereto, or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information concerning such Initial
Purchaser, furnished to Parent and the Subsidiaries by the Initial Purchasers
through DB specifically for use therein which information is set forth in
Section 12; and subject to the limitation set forth immediately preceding this
clause, will reimburse, as incurred, any legal or other expenses incurred by
Parent, any Subsidiary or any such director, officer or controlling person in
connection with investigating or defending against or appearing as a third party
witness in connection with any such loss, claim, damage, liability or action in
respect thereof. The indemnity provided for in this Section 9 will be in
addition to any liability that the Initial Purchasers may otherwise have to the
indemnified parties. The Initial Purchasers shall not be liable under this
Section 9 for any settlement of any claim or action effected without their
consent, which shall not be unreasonably withheld. Parent and the Subsidiaries
shall not, without the prior written consent of the Initial Purchasers, effect
any settlement or compromise of any pending or threatened proceeding in respect
of which any Initial Purchaser is or could have been a party, or indemnity could
have been sought hereunder by any Initial Purchaser, unless such settlement (A)
includes an unconditional written release of the Initial Purchasers, in form and
substance reasonably satisfactory to the Initial Purchasers, from all liability
on claims that are the subject matter of such proceeding and (B) does not
include any statement as to an admission of fault, culpability or failure to act
by or on behalf of any Initial Purchaser.

                  (c) Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action for which such indemnified
party is entitled to indemnification under this Section 9, such indemnified
party will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 9, notify the indemnifying party of the commencement
thereof in writing; but the omission to so notify the indemnifying party (i)
will not relieve it from any liability under paragraph (a) or (b) above unless
and to the extent such failure results in the forfeiture by the indemnifying
party of substantial rights and defenses and (ii) will not, in any event,
relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraphs (a) and (b)
above. In case any such action is brought against any indemnified party, and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified
party; provided, however, that if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party shall
have been advised by counsel that there may be one or more legal defenses
available to it and/or other indemnified parties that are different from or

                                      -22-

<PAGE>   23

additional to those available to the indemnifying party, or (iii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
the indemnified party to represent the indemnified party within a reasonable
time after receipt by the indemnifying party of notice of the institution of
such action, then, in each such case, the indemnifying party shall not have the
right to direct the defense of such action on behalf of such indemnified party
or parties and such indemnified party or parties shall have the right to select
separate counsel to defend such action on behalf of such indemnified party or
parties. After notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof and approval by such indemnified
party of counsel appointed to defend such action, the indemnifying party will
not be liable to such indemnified party under this Section 9 for any legal or
other expenses, other than reasonable costs of investigation, subsequently
incurred by such indemnified party in connection with the defense thereof,
unless (i) the indemnified party shall have employed separate counsel in
accordance with the proviso to the immediately preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated by the Initial Purchasers in the case
of paragraph (a) of this Section 9 or Parent or a Subsidiary in the case of
paragraph (b) of this Section 9, representing the indemnified parties under such
paragraph (a) or paragraph (b), as the case may be, who are parties to such
action or actions) or (ii) the indemnifying party has authorized in writing the
employment of counsel for the indemnified party at the expense of the
indemnifying party. All fees and expenses reimbursed pursuant to this paragraph
(c) shall be reimbursed as they are incurred. After such notice from the
indemnifying party to such indemnified party, the indemnifying party will not be
liable for the costs and expenses of any settlement of such action effected by
such indemnified party without the prior written consent of the indemnifying
party (which consent shall not be unreasonably withheld), unless such
indemnified party waived in writing its rights under this Section 9, in which
case the indemnified party may effect such a settlement without such consent.

                  (d) In circumstances in which the indemnity agreement provided
for in the preceding paragraphs of this Section 9 is unavailable to, or
insufficient to hold harmless, an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), each
indemnifying party, in order to provide for just and equitable contribution,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect (i) the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the offering of the Notes or (ii) if the
allocation provided by the foregoing clause (i) is not permitted by applicable
law, not only such relative benefits but also the relative fault of the
indemnifying party or parties on the one hand and the indemnified party on the
other in connection with the statements or omissions or alleged statements or
omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof). The relative benefits received by Parent and the
Subsidiaries on the one hand and any Initial Purchaser on the other shall be
deemed to be in the same proportion as the total proceeds from the offering
(before deducting expenses) received by Parent and the Subsidiaries bear to the
total discounts and commissions received by such Initial Purchaser. The relative
fault

                                      -23-

<PAGE>   24

of the parties shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
Parent and the Subsidiaries on the one hand, or such Initial Purchaser on the
other, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission or alleged
statement or omission, and any other equitable considerations appropriate in the
circumstances. Parent, the Subsidiaries and the Initial Purchasers agree that it
would not be equitable if the amount of such contribution were determined by pro
rata or per capita allocation or by any other method of allocation that does not
take into account the equitable considerations referred to in the first sentence
of this paragraph (d). Notwithstanding any other provision of this paragraph
(d), no Initial Purchaser shall be obligated to make contributions hereunder
that in the aggregate exceed the total discounts, commissions and other
compensation received by such Initial Purchaser under this Agreement, less the
aggregate amount of any damages that such Initial Purchaser has otherwise been
required to pay by reason of the untrue or alleged untrue statements or the
omissions or alleged omissions to state a material fact, and no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this paragraph (d), each person,
if any, who controls an Initial Purchaser within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act shall have the same rights to
contribution as the Initial Purchasers, and each director or officer of Parent
or a Subsidiary and each person, if any, who controls the Parent or any
Subsidiary within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, shall have the same rights to contribution as Parent or such
Subsidiary.

                  10. Survival Clause. The respective representations,
warranties, agreements, covenants, indemnities and other statements of Parent or
any Subsidiary, their respective officers and any Initial Purchaser set forth in
this Agreement or made by or on behalf of them pursuant to this Agreement shall
remain in full force and effect, regardless of (i) any investigation made by or
on behalf of Parent or Subsidiary, any of their respective officers or
directors, any Initial Purchaser or any other person referred to in Section 9
hereof and (ii) delivery of and payment for the Notes. The respective
agreements, covenants, indemnities and other statements set forth in Sections 6,
9 and 15 hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement.

                  11. Termination. (a) This Agreement may be terminated in the
sole discretion of each Initial Purchaser by notice to Parent given prior to the
Closing Date in the event that the Parent or any Subsidiary shall have failed,
refused or been unable to perform in all material respects all obligations and
satisfy in all material respects all conditions on their respective parts to be
performed or satisfied hereunder at or prior thereto or, if at or prior to the
Closing Date:

                  (i) any of Parent or the Subsidiaries shall have sustained any
         loss or interference with respect to its businesses or properties from
         fire, flood, hurricane, accident or other calamity, whether or not
         covered by insurance, or from any strike, labor dispute, slow down or
         work stoppage or any legal or governmental proceeding, which loss or
         interference, in the sole judgment of such Initial Purchaser, has had
         or could reasonably be expected to have a Material Adverse Effect, or
         there shall have been, in the

                                      -24-

<PAGE>   25

         sole judgment of such Initial Purchaser, any event or development that,
         individually or in the aggregate, has had or could reasonably be
         expected to have a Material Adverse Effect (including without
         limitation a change in control of Parent or any of the Subsidiaries),
         except in each case as described in the Memorandum (exclusive of any
         amendment or supplement thereto);

                  (ii) trading in securities generally on the New York Stock
         Exchange, American Stock Exchange or the NASDAQ National Market shall
         have been suspended or minimum or maximum prices shall have been
         established on any such exchange or market;

                  (iii) any securities of Parent or any Subsidiary shall have
         been downgraded or placed on any "watch list" for possible downgrading
         by any nationally recognized statistical ratings organization;

                  (iv) a banking moratorium shall have been declared by New York
         or United States authorities; or

                  (v) there shall have been (A) an outbreak or escalation of
         hostilities between the United States and any foreign power, or (B) an
         outbreak or escalation of any other insurrection or armed conflict
         involving the United States or any other national or international
         calamity or emergency, or (C) any material change in the financial
         markets of the United States which, in the case of (A), (B) or (C)
         above and in the sole judgment of such Initial Purchaser, makes it
         impracticable to proceed with the offering or the delivery of the Notes
         as contemplated by the Final Memorandum.

                  (b) Termination of this Agreement pursuant to this Section 11
shall be without liability of any party to any other party except as provided in
Section 10 hereof.

                  12. Information Supplied by the Initial Purchasers. The
statements set forth in the second and third sentences of paragraph 3, the third
sentence of paragraph 6, and in paragraph 7 under the heading "Private
Placement" in the Memorandum (to the extent such statements relate to the
Initial Purchasers) constitute the only information furnished by the Initial
Purchasers to the Company for the purposes of Sections 2(a) and 9 hereof.

                  13. Notices. All communications hereunder shall be in writing

their respective successors and legal representatives, and nothing expressed or

AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY

                  Subject to the terms and conditions set forth herein, the
parties hereto, and certain other Persons described herein, desire to consummate
each of the following: (i) H.I.G. Cable, Inc., a Cayman Islands corporation
("HIG Cable"), desires to sell to LISN, Inc., an Ohio corporation ("Purchaser")
for cash, and Purchaser desires to purchase from HIG for cash, certain shares of
Orius Series A Preferred Stock, par value $.01 per share ("Orius Series A
Preferred") and the Orius Convertible Note (as further described below, the
"Purchase Transaction"); (ii) H.I.G. Cable West, Inc., a Cayman Islands
corporation ("HIG West" and, collectively with HIG Cable, "HIG"), desires to
enter into an agreement with Purchaser (as further described below, the "HIG Put
Agreement") pursuant to which at HIG West's election at a future date HIG West
will be entitled to sell to Purchaser for cash all of its shares of Orius Series
B Preferred Stock, par value $.01 per share ("Orius Series B Preferred"), which
shares constitute all interests in Orius held by HIG other than those which HIG
sells to Purchaser as contemplated by clause (i), and Purchaser desires to enter
into an agreement with HIG West pursuant to which at Purchaser's election HIG
West will be obligated to sell to Purchaser for cash the Orius Series B
Preferred (as further described below, the "HIG Call Agreement"); (iii) holders
of Orius common stock, $.01 par value per share (the "Orius Common Stock"),
desire to exchange certain shares of such common stock for certain newly
authorized junior subordinated notes of Orius (as further described below, the
"Orius Junior Notes") and Orius Series C Participating Preferred Stock, par
value $.01 per share (as further described below, the "Series C Participating
Preferred") and cash; (iv) certain holders of Orius Common Stock desire to enter
into an agreement with Orius (as further described below, collectively, the
"Orius Put Agreements") pursuant to which, at each such holder's election at a
future date, such holder will be entitled to sell to Orius certain shares of
Orius Common Stock for cash, Series C Participating Preferred and Orius Junior
Notes, and Orius desires to enter into an agreement with each such holder (as
defined below, collectively, the "Orius Call Agreements") pursuant to which, at
Orius's election, each such holder will be obligated to sell to Orius such Orius
Common Stock for cash, Series C Participating Preferred and Orius Junior Notes,
as specified therein; (v) certain holders of Orius Common Stock, and the holders
of all outstanding Orius Warrants (each of such Persons listed on the Orius
Warrantholders Schedule hereto, an "Orius Warrantholder", and all of such
Persons collectively, the "Orius Warrantholders"), desire to sell to Orius for
cash, and Orius desires to purchase from such Persons for cash, all of their
shares of Orius Common Stock and Orius Warrants; (vi) Orius desires to acquire
LISN, and LISN desires to be acquired by Orius, by means of a merger of Merger
Sub with and into LISN, with LISN surviving such merger, and with all of LISN's
outstanding common stock (other than the Vanke Shares, which shall remain
outstanding after the LISN Merger), and preferred stock being converted thereby
into shares of Orius Class B Common Stock, par value $.01 per share (the "Orius
Class B Common" and, collectively with the Orius Common Stock, the "Orius


<PAGE>   10



Common") and Series C Participating Preferred (as further described below, the
"LISN Merger"), with all outstanding options to acquire LISN common stock being
converted thereby into options to acquire Orius Class B Common and Series C
Participating Preferred, and by means of an exchange of Orius Junior Notes for
all outstanding LISN junior subordinated notes, and all accrued and unpaid
interest thereon (as further described below, the "Note Exchange" and,
collectively with the New LISN Note Exchange and the LISN Merger, the "LISN
Merger Transactions"); (vii) Orius desires to terminate all outstanding Orius
employee stock options contemporaneously with the consummation of the foregoing
transactions and make certain cash payments to the holders thereof; and (viii)
Orius and LISN desire to finance the transactions contemplated hereby, including
related fees and expenses, and to refinance all of their respective existing
senior bank debt, through (A) the issuance by certain Subsidiaries of Orius and
LISN of senior debt and senior subordinated debt and (B) the issuance and sale
by LISN to Willis Stein and others (collectively, as further described below,
the "Investors") of New LISN Notes (as further described below, the "Investment
Transaction"). The New LISN Notes issued to the Investors at or prior to the
Closing pursuant to the Investment Transaction will be converted into Orius
Class B Common, Series C Participating Preferred and Orius Junior Notes pursuant
to the LISN Merger (as further described below, the "New LISN Note Exchange").

         Effective Time. At the Effective Time, (x) the outstanding shares of
         LISN Common will convert by operation of law into an aggregate number

         Common Share Number and an aggregate number of shares of Series C
         Participating Preferred equal to the LISN Common Stockholders Preferred

         Series C Participating Preferred, and (z) the Existing LISN Employee
         Options will convert by operation of law into the Converted LISN
         Employee Options. For the avoidance of doubt, the parties acknowledge
         that if the Vanke Exchange has been consummated prior to the Closing,
         then the Vanke Shares will be LISN Class C Common and, notwithstanding
         any other provision hereof, will


                                       -5-

         of the LISN Merger and shall remain outstanding thereafter subject to
         repurchase by LISN pursuant to the LISN Recapitalization Agreement. For
         the avoidance of doubt, the sum of the LISN Common Stockholders
         Preferred Share Number and the LISN Preferred Stockholders Preferred
         Share Number issued at the Effective Time shall not exceed the LISN
         Shareholders Preferred Share Number.

         the conditions set forth in the Note Exchange Agreement in the form
         attached hereto as Exhibit G (the "Note Exchange Agreement"), as of the

         Orius LISN Junior Notes to Orius in the aggregate initial principal
         amount set forth opposite such Person's name on Exhibit B(ii) hereto in

         principal amount equal to the aggregate principal amount of, plus
         accrued and unpaid interest on, the LISN Junior Notes so exchanged,

         issued to the Investors pursuant to the Investment Agreement, and to
         the holders thereof in exchange therefor, (A) an aggregate number of

                           (c) Issuance and Delivery of LISN Merger Transactions
         Consideration. As of the Effective Time, to each Person holding LISN
         Common or LISN Preferred (collectively, the "LISN Shareholders") who

         aggregate initial principal amount to be exchanged by such Person as
         set forth opposite such Person's name on Exhibit B(i) hereto pursuant
         to the Note Exchange, in each case under the caption "LISN Securities",

         Series C Participating Preferred into which such shares of LISN Common
         converted in the LISN Merger, the number of shares of Series C

         of, plus accrued and unpaid interest on, such LISN Junior Notes so
         delivered. At the written request of any such LISN Shareholder that
         Orius deliver to such LISN Shareholder prior to the final determination
         of Closing LISN Investor Value pursuant to Section 1E below,
         certificates for the securities issued to such Person in accordance
         with the foregoing, Orius shall (x) promptly deliver to such Person

Orius Stockholders Schedule hereto under the heading "Full Strip Exchange",
Orius shall, at the Closing:

                           (a) deliver cash in an amount equal to 95% of the

         Per Old Common Share multiplied by such number of outstanding shares of
         Orius Common Stock set forth opposite such Person's name on the Orius
         Stockholders Schedule hereto under the heading "Full Strip Exchange";

                           (c) issue Orius Junior Notes in an aggregate

         and

                           (d) promptly after the determination of Closing Orius
         Investor Value and Closing LISN Investor Value pursuant to Section 1E,
         Orius shall return to such Orius Stockholder the number of shares of
         Orius Common Stock equal to four and one-half percent (4.5%) multiplied
         by such number of outstanding shares of Orius Common Stock set forth
         opposite such Person's name on the Orius Stockholders Schedule hereto
         under the heading "Full Strip Exchange" and originally tendered by such
         Orius Stockholder to Orius.

         At the Closing, contemporaneously with delivering to each of the Orius
         Stockholders the cash consideration described in (a) above, Orius will
         deliver to the Escrow Agent pursuant to subsection (ix) below, 5% of
         the Full Strip Cash Consideration Per Old Common Share, as estimated
         pursuant to Section 1D, multiplied by the number of outstanding shares
         of Orius Common Stock set forth opposite such Person's name on the
         Orius Stockholders Schedule hereto under the heading "Full Strip
         Exchange."

                  FOR EXAMPLE: If (i) the Orius Common Value Per Share is $10,
                  the Note Proportion is 35% and the Preferred Stock Proportion
                  is 55%, and (ii) the number of outstanding shares of Orius
                  Common Stock set forth opposite the name of an Orius
                  Stockholder on the Orius Stockholders Schedule hereto under
                  the heading "Full Strip Exchange" is 100, and such Orius
                  Stockholder executes and delivers to Orius a Full Strip
                  Joinder Agreement in respect of such 100 shares, and at the
                  Closing delivers to Orius certificates representing such 100
                  shares, endorsed as required under the Joinder Agreement, then
                  Orius will deliver to such Orius Stockholder at the Closing,
                  $475 in cash (i.e., 95% of the product of 50% multiplied by
                  100 shares multiplied by $10 per share) and, after final
                  determinations pursuant to Section 1E, Orius Junior Notes in
                  an aggregate initial principal amount equal to $175 (i.e., 35%
                  multiplied by 50% multiplied by 100 shares multiplied by $10
                  per share) and 0.275 shares of Series C Participating
                  Preferred (i.e., 55% multiplied by 50% multiplied by 100
                  shares multiplied by $10 per share, divided by $1,000). Orius
                  would return to such Orius Stockholder 4.5 shares of Orius
                  Common Stock. At the Closing, Orius would also deliver $25 in
                  cash (i.e., 5% of the product of 50% multiplied by 100 shares
                  multiplied by $10 per share) to the Escrow Agent pursuant to
                  subsection (ix) below. If the assumptions set forth in clause
                  (i) are confirmed pursuant to the procedures described in
                  Section 1E, upon confirmation thereof the Escrow Agent will
                  pay to such Orius Stockholder the $25, subject only to the
                  other restrictions on distribution set forth in the Escrow
                  Agreement. If, pursuant to the procedures described in Section
                  1E, it is determined that the Orius Common Value Per share is
                  $9.90 and the other assumptions stated above are correct, the
                  Escrow Agent would immediately refund to Orius $5 in respect
                  of such Orius Stockholder (i.e., the excess of $500, the
                  aggregate cash paid by Orius to such Orius Stockholder and to
                  the Escrow Agent in respect of such


                                       -8-

<PAGE>   17

                  Orius Stockholder, over $495, the total amount of cash to
                  which such Orius Stockholder is entitled (i.e., 50% multiplied
                  by 100 shares multiplied by $9.90 per share). Also, upon such
                  a determination, the number of shares of Series C
                  Participating Preferred and amount of Orius Junior Notes
                  issuable to such Orius Stockholder would be recalculated (to
                  be .27225 share and $173.25 principal amount) and delivered in
                  lieu of the amounts previously delivered.

                  (v) Exchange of Orius Common for "Securities Only". To each of
the Orius Stockholders who has executed and delivered to Orius on or prior to
the date hereof an Orius Joinder and Transmittal Agreement (Securities Only) in
the form attached hereto as Exhibit I(v) and dated as of the date hereof (each a
"Securities Only Joinder Agreement", and all such Securities Only Joinder
Agreements, collectively, the "Securities Only Joinder Agreements"), and who has
delivered to Orius at or prior to the Closing the certificates, duly endorsed
for transfer as required by such Securities Only Joinder Agreements,
representing the number of outstanding shares of Orius Common Stock set forth
opposite such Person's name on the Orius Stockholders Schedule hereto under the
heading "Securities Only Exchange", and who has deposited (or for whom a deposit
has been made) with the Escrow Agent, cash in an amount equal to 2.5% of the
value at Closing of the Orius securities to be issued to such Stockholder
pursuant to subparagraphs (a), (b) and (c) below, Orius shall, at the Closing:

                           (a) issue the number of shares of Series C
         Participating Preferred equal to the Securities Only Preferred
         Consideration Per Old Common Share multiplied by such number of
         outstanding shares of Orius Common Stock set forth opposite such
         Person's name on the Orius Stockholders Schedule hereto under the
         heading "Securities Only Exchange";

                           (b) issue Orius Junior Notes in an aggregate
         principal amount equal to the Securities Only Junior Note Consideration
         Per Old Common Share multiplied by such number of outstanding shares of
         Orius Common Stock set forth opposite such Person's name on the Orius

                  1D.      Determination of Estimated Orius Investor Value and
Estimated LISN Investor Value.


                  (i)      Estimated Orius Net Indebtedness. Not more than five
(5) Business Days, but in no event less than two (2) Business Days, before the
Closing Date, Orius shall deliver to LISN a balance sheet of Orius as of the

<PAGE>   21

faith to resolve their differences, each such amount will be revised to be
mutually acceptable to such persons and the resulting estimate of Orius's Net
Indebtedness shall be deemed to be "Estimated Orius Net Indebtedness".

                  (ii) Estimated LISN Net Indebtedness. Not more than five (5)

financial officer setting forth his estimate of LISN's Net Indebtedness as of
the close of business on the day before the Closing Date and supporting detail,
including each item of such Indebtedness. If the Orius Stockholders
Representative disagrees with any amount set forth on such certificate, LISN's
chief financial officer and such Representatives will negotiate in good faith to
resolve their differences, each such amount will be revised to be mutually
acceptable to such persons and the resulting estimate of LISN's Net Indebtedness
shall be deemed to be "Estimated LISN Net Indebtedness".

                  (iii) Definition of Net Indebtedness. For purposes hereof,
"Net Indebtedness" of any Person means the aggregate amount of such Person's
Indebtedness determined on a consolidated basis in accordance with GAAP,
assuming for such purposes that the full amount thereof shall be repaid on such
date, less the aggregate amount of cash or Cash Equivalents held by such Person
and its Subsidiaries on a consolidated basis, as reflected in its books and
records in accordance with GAAP, in each case determined as of the close of
business on the day before the Closing Date and without giving effect to the
Investment Transaction, the Purchase Transaction, or the transactions
contemplated by any of Orius Put Agreements, Orius Call Agreements, the HIG Put
Agreement and the HIG Call Agreement.

                  (iv) Definition of Estimated Investor Value. For purposes of

         twelve-month period ending December 31, 1999) less (ii) the Estimated
         Orius Net Indebtedness, plus (iii) the Aggregate Orius Option Exercise

                           (b) "Estimated LISN Investor Value" means the product
         of 8.42 times $30.0 million (LISN's estimated EBITDA for the
         twelve-month period ending December 31, 1999) less the Estimated LISN

                  (i) Determination of Closing Orius Investor Value and Closing
LISN Investor Value.

                  (a) Within 10 business days after the Closing Date, Orius will
prepare, and deliver to the Representatives its calculation of Orius's Net
Indebtedness and LISN's Net Indebtedness, the Aggregate Orius Option Exercise
Price, and the resulting Closing Orius Investor Value and Closing
LISN Investor Value (the "Orius Notice"). Orius will make available to the
Representatives and their advisors all records and work papers used in preparing
the materials so delivered to such Representative. If any Representative
disagrees with the computation of Orius's Net Indebtedness or LISN's Net
Indebtedness, or with any other determination, such Representative may, within
five (5) days after receipt of Orius Notice to such Representative, deliver a
notice (an "Objection Notice") to Orius setting forth such Representative's
objection to Orius's calculation which is the subject of the Objection Notice,
and the basis for such objection. Upon receipt of any Objection Notice relating
to Orius's Net Indebtedness from any Representative, Orius will promptly deliver
copies thereof to each other Representative, and upon receipt of any Objection
Notice relating to the LISN Net Indebtedness from the Orius Stockholders
Representative, the LISN Shareholder Representative or the Investor
Representative, Orius will promptly deliver copies thereof to each of the other
of such three Representatives. Orius and the Representatives will use reasonable
efforts to resolve any disagreements as to the computation of Orius's Net
Indebtedness, LISN's Net Indebtedness or any other amount, as applicable, but if
they do not obtain a final resolution within ten (10) days after Orius has
delivered the Objection Notices (if any are so received) in accordance with the
foregoing sentence, Orius and the Representatives will jointly retain either of
Deloitte & Touche LLP or Arthur Andersen (such selected firm, the "Firm") to
resolve any remaining disagreements. Orius and the Representatives will direct
the Firm to render a determination within 10 days of its retention and Orius,
the Representatives and their respective agents will cooperate with the Firm
during its engagement. The Firm will consider only those items and amounts
identified in the Objection Notices which Orius and the Representatives are
unable to resolve. In resolving any disputed item, the Firm may not assign a
value to any item greater than the greatest value for such item claimed by Orius
or any Representative or less than the smallest value for such item claimed by
Orius or any Representative. The Firm's determination will be based solely on
presentations by Orius and the Representatives (i.e., not on independent
review), and in accordance with GAAP. The determination of the Firm will be
conclusive and binding upon Orius, the Representatives, the LISN Shareholders,
the Orius Stockholders and the Investors. The costs and expenses of the Firm
shall be allocated by the Firm, on the basis deemed to be equitable by the Firm,
to Orius or LISN and, for purposes of the adjustments contemplated hereby,
treated as Net Indebtedness of Orius or LISN as of the end of the day
immediately preceding the Closing Date. The amount of Orius's Net Indebtedness
and LISN's Net Indebtedness, as each is finally determined pursuant to this
Section, is referred to herein as the "Final Orius Net Indebtedness" and the
"Final LISN Net Indebtedness," respectively.

                  (ii) For purposes of this Agreement:

                           (a) "Closing Orius Investor Value" means (i) the
         product of 8.42 times $57.55 million (Orius's estimated EBITDA for the
         twelve-month period ending December 31, 1999) less (ii) the Final Orius
         Net Indebtedness, plus (iii) the Aggregate Orius Option Exercise Price.

                           (b) "Closing LISN Investor Value" means the product
         of 8.42 times $30.0 million (LISN's estimated EBITDA for the
         twelve-month period ending December 31, 1999) less the Final LISN Net
         Indebtedness.

                  (iii) Adjustments Based Upon Closing LISN Investor Value and
Closing Orius Investor Value. If and to the extent that Closing LISN Investor
Value deviates from Estimated LISN Investor Value, or Closing Orius Investor
Value deviates from Estimated Orius Investor Value, Orius shall deliver notice
thereof (the "Final Consideration Notice") to each of the Representatives,
stating (a) Closing Orius Investor Value, the Orius Common Value Per Share and
Closing LISN Investor Value, as finally determined, (b) the number of shares of
Orius Common, the number of shares of Series C Participating Preferred and the
aggregate initial principal amount of Orius Junior Notes to which each LISN
Shareholder was entitled at the Closing pursuant to this Agreement and the other
agreements contemplated hereby (the "Final LISN Consideration), (c) the number
of shares of Series C Participating Preferred, the aggregate initial principal
amount of Orius Junior Notes and the aggregate amount of cash to which each
Orius Stockholder and each Orius Warrantholder was entitled at the Closing
pursuant to this Agreement and the other agreements contemplated hereby,
including without limitation the HIG Call Agreement and the Purchase Agreement
(the "Final Orius Consideration"), (d) the Orius Option Spread Value in respect
of each Existing Orius Option, (e) if any of the Orius Stockholders or Orius
Warrantholders (or the Escrow Agent, as applicable) has theretofore received
cash, shares of Series C Participating Preferred or Orius Junior Notes, the
amount of any reconciling payment or delivery by Orius to such Orius Stockholder
or Orius Warrantholder (or the Escrow Agent, as applicable) that will be
necessary to ensure that such Orius Stockholder or Orius Warrantholder (or the
Escrow Agent, applicable) has received or will receive cash, shares of Series C
Participating Preferred and Orius Junior Notes in aggregate amounts equal to,
and not more than or less than, such Orius Stockholder's or Orius

or such LISN Shareholder that will be necessary to ensure that such LISN
Shareholder has received or will receive shares of Orius Class B Common, shares
of Series C Participating Preferred and Orius Junior Notes in aggregate amounts
equal to, and not more than or less than, such LISN Shareholder's Final LISN
Consideration. Orius and each of the Orius Stockholders and LISN Shareholders

days, following receipt of, and in accordance with the instructions set forth

on the attached Orius Contracts Schedule). Neither Orius, any of its
Subsidiaries nor any of the Orius Stockholders is a party to or bound by any

respect to an Orius Transaction other than this Agreement and the other
agreements contemplated hereby. Neither Orius nor, to Orius's Knowledge, HIG has

and interest to, or has the right to use pursuant to a valid and enforceable
license, all Intellectual Property Rights necessary for the operation of its

set forth on the attached Orius Intellectual Property Schedule, the loss or
expiration of any Intellectual Property Right or related group of Intellectual
Property Rights owned or used by Orius or any of its Subsidiaries has not had
and would not reasonably be expected to have a Material Adverse Effect, and no
loss or expiration of any Intellectual Property Right is threatened, pending or,
to Orius's Knowledge, reasonably foreseeable. Each of Orius and its Subsidiaries
has taken commercially reasonable steps to maintain and protect the Intellectual
Property Rights which it owns.

                  (ii) Except as set forth on the attached Orius Intellectual
Property Schedule, (a) there have been no claims made against Orius or any of
its Subsidiaries asserting the invalidity, misuse or unenforceability of any of

(b) neither Orius nor any of its Subsidiaries has received any written notices
of, and to Orius's Knowledge neither Orius nor any of its Subsidiaries has
received any unwritten notice of, and has no Knowledge of, any facts which

with, any third party with respect to any Intellectual Property Rights
(including any demand or request that Orius or any of its Subsidiaries license
any rights from a third party), (c) to Orius's Knowledge the conduct of Orius's
and its Subsidiaries' businesses has not infringed, misappropriated or
conflicted with and does not infringe, misappropriate or conflict with any
Intellectual Property Rights of other Persons, and (d) to Orius's Knowledge, the
Intellectual Property Rights owned by or licensed to Orius or any of its
Subsidiaries have not been infringed, misappropriated or conflicted by other
Persons. The transactions contemplated by this Agreement will have no Material
Adverse Effect on Orius's and its Subsidiaries' right, title or interest in and
to the Intellectual Property Rights listed on the Orius Intellectual Property
Schedule, and all of such Intellectual Property Rights shall be owned or
available for use by Orius and its Subsidiaries on terms and conditions
immediately after the Closing which are substantially identical to those in

proceedings (including any arbitration proceedings), orders, investigations or
claims pending or, to Orius's Knowledge, threatened against or any material
actions, suits, proceedings (including any arbitration proceedings), orders,
investigations or claims affecting Orius or any of its Subsidiaries (or to

of any of the 35 most highly compensated employees of Orius and its Subsidiaries
on a consolidated basis, their use in connection with Orius's or any of its
Subsidiaries' businesses of any information or techniques allegedly proprietary

Securities, Inc. pursuant to the agreement described on the Orius Contracts
Schedule attached hereto, there are and shall be no claims for brokerage
commissions, finders' fees or similar compensation in connection with the
transactions contemplated by this Agreement based on any arrangement or
agreement to which Orius or any of its Subsidiaries is a party or to which Orius
or any of its Subsidiaries is subject, it being acknowledged and agreed that any
such brokerage commissions, finder's fees or similar compensation shall be
deemed to be Indebtedness of Orius for purposes of this Agreement.

                  5R. Insurance. The attached Orius Insurance Schedule contains
a description of each insurance policy maintained by Orius and any of its
Subsidiaries with respect to its and any of its Subsidiaries' properties, assets
and business, together with a statement of the aggregate amount of claims paid
out, and claims pending, under each such insurance policy or other arrangement
through the date hereof. All such policies are in full force and effect as of
the Closing, all premiums due thereon have been paid, and Orius and its
Subsidiaries are otherwise in compliance in all material respects with the terms
and provisions of such policies. Neither Orius nor any of its Subsidiaries is in
default with respect to its obligations under any insurance policy maintained by
it, and neither Orius nor any of its Subsidiaries has received any notice of
cancellation or non-renewal of any such policy or arrangement nor is the
termination of any such policies or arrangements threatened. Neither Orius nor
any of its Subsidiaries has ever been denied insurance coverage, and there is no
claim pending under any policies or arrangements as to which coverage has been
questioned, denied or disputed by the underwriters of such policies or
arrangements. Neither Orius nor any of its Subsidiaries has received any notice
from any of its insurance carriers that any insurance premiums will be increased
in the future or that any insurance coverage presently provided for will not be

same terms as now in effect and none of such policies or arrangements provides
for any retrospective premium adjustment, experienced-based liability or loss
sharing arrangement affecting Orius or any of its Subsidiaries. A true and

$10,000 made by or with respect to any single employee of Orius or any of its
Subsidiaries is set forth in the Orius Insurance Schedule. Except as set forth

Orius has no self-insurance or co-insurance programs, and the reserves set forth

Liabilities with respect to any such self-insurance or co-insurance programs.

                  5S. Employees. To Orius's Knowledge, no executive or key
employee of Orius or any of its Subsidiaries and no group of employees of Orius
or any of its Subsidiaries has any plans to terminate employment with Orius or
such Subsidiary. Orius has no material labor relations problems (including any
union organization activities, threatened or actual strikes or work stoppages or
material grievances). None of Orius, the Orius Stockholders nor, to Orius's
Knowledge, any of its other employees or consultants are subject to any
noncompete, nondisclosure, confidentiality, employment, consulting or other
agreement or judgment, decree or order of any court or administrative agency,
relating to, affecting or in conflict with the present or proposed business
activities of Orius and its Subsidiaries or such Person's duties to Orius and
its Subsidiaries, except for agreements between Orius and its present and former
employees. Orius has not received any written notice alleging that any violation
of any such agreements has occurred, and to Orius's Knowledge neither Orius nor
any of its Subsidiaries has received any unwritten notice thereof. The Orius
Employees Schedule attached hereto contains a correct and complete list of all
employees and consultants of Orius which have executed and delivered to Orius
any agreement providing for the nondisclosure by such Person of any confidential

                  5T. ERISA.

                  (i) Except as set forth on the attached Orius Employee
Benefits Schedule, Orius does not have any obligation to contribute to (or any
other liability, including current or potential withdrawal liability, with
respect to) any "multi-employer plan" (as defined in Section 3(37) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")).

                  (ii) Orius does not maintain or have any obligation to
contribute to (or any other liability with respect to) any plan or arrangement,
whether or not terminated, which provides medical, health, life insurance or
other welfare-type benefits for current or future retired or terminated
employees or any dependents of such employees (except for limited continued
medical benefit coverage required to be provided under Section 4980B of the Code
("COBRA") or as required under applicable state law).

                  (iii) Orius does not maintain, contribute to or have any
actual or potential liability under (or with respect to) any employee plan which
is a "defined benefit plan" (as defined in Section 3(35) of ERISA).

                  (iv) Except as set forth on the attached Orius Employee
Benefits Schedule, Orius does not maintain, contribute to or have any actual or
potential liability under (or with respect to) any employee plan which is a
"defined contribution plan" (as defined in Section 3(34) of ERISA) (the
"Plans"), whether or not terminated.

                  (v) Except as set forth on the attached Orius Employee
Benefits Schedule under the heading "Other Plans" (the "Other Plans"), Orius
does not maintain, contribute to or have any


                                      -41-

<PAGE>   50


actual or potential liability under (or with respect to) any plan or arrangement
providing benefits or remuneration to current or former employees or independent
contractors, including any employment contract, bonus or incentive plan, plan
for deferred compensation, employee health or other welfare benefit plan,
severance arrangement or other material policy, program or arrangement, whether
or not terminated. The attached Orius Employee Benefits Schedule sets forth the
aggregate amount of bonuses and other incentive compensation reasonably expected
to be paid by Orius for the fiscal year ending December 31, 1999.

                  (vi) With respect to the Plans set forth on the attached Orius
Employee Benefits Schedule, all required payments, premiums, contributions,
reimbursements or accruals for all periods ending prior to or as of the Closing
Date shall have been made or properly accrued. None of the Plans has any
material unfunded liabilities which are not reflected on the Latest Balance
Sheet.

                  (vii) Except as set forth on the attached Orius Employee
Benefits Schedule, the Plans and all related trusts, insurance contracts and
funds have been maintained, funded and administered in compliance in all
material respects with the applicable provisions of ERISA, the Code and other
applicable laws. Except as set forth on the attached Orius Employee Benefits
Schedule, Orius has timely complied with all reporting and disclosure
obligations as they apply to the Plans, and Orius has complied with the
requirements of COBRA. To Orius's Knowledge, none of Orius or any trustee or
administrator of any Plan has engaged in any transaction with respect to the
Plans which would subject Orius or any trustee or administrator of the Plans, or
any party dealing with any such Plan, nor do the transactions contemplated by
this Agreement constitute transactions which would subject any such party, to
either a civil penalty assessed pursuant to Part 502(i) of ERISA, or any other
penalty or excise tax or the tax or penalty on prohibited transactions imposed
by Section 4975 of the Code or any other penalty or excise tax. No actions,
suits or claims with respect to the assets of the Plans (other than routine
claims for benefits) are pending or, to Orius's Knowledge, threatened which
could result in or subject Orius to any liability and there are no circumstances
which would give rise to or be expected to give rise to any such actions, suits
or claims.

                  (viii) The attached Orius Employee Benefits Schedule sets
forth whether or not a favorable determination letter from the Internal Revenue
Service has been received by Orius with respect to each Plan that it is
qualified under Section 401(a) of the Code (including requirements imposed by
the Tax Reform Act of 1986 and subsequent legislation), and, to Orius's
Knowledge, there are no circumstances which would cause a Plan to lose such
qualified status.

                  (ix) For purposes of this Section 5T, "Orius" shall be deemed
to include all organizations under common control with Orius pursuant to Section
414 of the Code.

or any of its Subsidiaries alleging a violation of any such laws, ordinances,
codes, rules, requirements or regulations.

permits, licenses, bonds, approvals, accreditations, certificates, registrations
and authorizations will be available for use by Orius and its Subsidiaries, as
the case may be, immediately after the Closing.

         in all material respects with and is in material compliance with all
         Environmental and Safety Requirements. Neither Orius nor any of its

         relating to it or its facilities arising under Environmental and Safety
         Requirements.

                           (b) Neither this Agreement nor the consummation of
         the transactions contemplated hereby will result in any obligations for
         site investigation or cleanup, or notification to or consent of any
         government agencies or third parties under any Environmental and Safety
         Requirements (including any so called "transaction-triggered" or
         "responsible property transfer" laws and regulations).

                           (c) None of the following exists at any property or

         treated, stored, disposed of, arranged for or permitted the disposal
         of, transported, handled or Released any substance (including any
         hazardous substance) or owned, occupied or operated any facility or
         property (and no such property or facility is contaminated by any such
         substance) in a manner that has given or could give rise to any
         Liabilities (including any Liability for response costs, corrective
         action costs, personal injury, natural resource damages, property
         damage or attorneys fees or any investigative, corrective or remedial
         obligations) pursuant to CERCLA or any other Environmental and Safety
         Requirements.

                           (e) Neither Orius nor any of its Subsidiaries has,

forth a list of all of the leases, subleases and licenses ("Orius Leases") of
real property (the "Orius Leased Real Property"), including the address of the
Orius Leased Real Property, in which Orius or any of its Subsidiaries has a
leasehold, subleasehold or licensed interest, other than any lease which may be
terminated by either party without liability to the other on less than 90 days
notice or involving aggregate annual rentals of less than $50,000, not otherwise
involving any material liability and the termination of which would not have a
Material Adverse Effect. Orius or such Subsidiary holds a valid and existing
leasehold, subleasehold or license interest under each of the Orius Leases. With
respect to each Orius Lease listed on the attached Orius Real Property Schedule,
neither Orius, any of its Subsidiaries, nor, to the Knowledge of Orius, any
other party to the Orius Lease is in breach or default under the Orius Lease,
and no event has occurred or circumstance exists which, with the delivery of
notice, passage of time or both, would constitute such a breach or default or
permit the termination, modification or acceleration of rent under the Orius
Lease, there are no disputes, oral agreements, or forbearance programs in effect
as to such Orius Lease and neither Orius nor any of its Subsidiaries has
assigned, transferred, conveyed, mortgaged, deeded in trust or encumbered any
interest in the Orius Lease. Except for the Orius Leased Real Property, and the
Orius Owned Real Property, there is no real property which is leased or
otherwise used in Orius's business.

                  5Z. Regulatory Status. Since its date of incorporation,

shall not be, a "United States real property holding corporation," as defined in
Section 897(c)(2) of the Code and in Section 1.897-2(b) of the Treasury
Regulations issued thereunder. Neither Orius nor any of its Subsidiaries is an
"investment company" or an "affiliated person" of, or "promoter" or "principal
underwriter" for, an "investment company," as such terms are defined under the
Investment Orius Act of 1940, as amended. Neither Orius nor any of its
Subsidiaries is subject to any law which regulates the incurring of indebtedness
(other than certain corporation law statutes which prohibit a corporation from
incurring indebtedness if doing so would cause such corporation to become
insolvent) by Orius or such Subsidiary,


                                      -46-

including any laws relating to common contract carriers or the sale of
electricity, gas, steam, water or other public utility services.

by such other agreements, LISN hereby represents and warrants to Orius and the
Orius Stockholders as follows:

corporation duly organized, validly existing and in good standing under the laws
of the State of Ohio, and is qualified to do business in every jurisdiction in
which its ownership of property or conduct of business requires it to qualify

not have a Material Adverse Effect. LISN possesses all requisite corporate power
and authority necessary to own and operate its properties, to carry on its
businesses as now conducted and presently proposed to be conducted and to carry
out the transactions contemplated by this Agreement. The copies of LISN's
articles of incorporation and Code of Regulations which have been furnished to
Orius' counsel reflect all amendments made thereto at any time prior to the date
of this Agreement and are correct and complete. The articles of incorporation
furnished to Orius will, as of the Closing Date, reflect all amendments made

                  6B. Capital Stock and Related Matters.

                  (i) As of the date hereof, and without giving effect to any of

exercise of Existing LISN Employee Options. Other than the outstanding shares of
LISN Common and LISN Preferred described above, LISN does not have and as of the
Closing Date will not have outstanding any stock or securities, or any stock or
securities convertible into or exercisable or exchangeable for any shares of its
capital stock or containing any profit participation features, nor any rights or

otherwise acquire or retire any shares of its capital stock or any warrants,
options or other rights to acquire its capital stock, other than as expressly
provided in this Agreement and, as of the Closing, pursuant to the articles of

Employee Options was issued pursuant to an option agreement in the form
previously delivered to LISN and the terms thereof are set forth in such option
agreement and the Stock Option Plan.

                  (ii) Prior to the execution and delivery of the Investor

attached LISN Investments and LISN Subsidiaries Schedule, LISN does not own or
hold the right to acquire any shares of stock or any other security or interest
in any other Person. The attached LISN Investments and LISN Subsidiaries

its businesses as now being conducted and as presently proposed to be conducted
and is qualified to do business in every jurisdiction in which its ownership of
property or the conduct of business requires it to qualify, except where the

outstanding shares of capital stock of each Subsidiary are validly issued, fully
paid and nonassessable, and all such shares are owned by LISN or another
Subsidiary free and clear of any Lien (other than Existing Bank Liens) and are
not subject to any option or right to purchase any such shares. Except as set
forth on the LISN Investments and LISN Subsidiaries Schedule attached hereto,
LISN has never had any Subsidiaries. Except as set forth on the LISN Investments
and LISN Subsidiaries Schedule, LISN does not have any obligation to make any
additional Investments in any Person.

performance of this Agreement and all of the other agreements and instruments
contemplated hereby to which LISN is a party, and the consummation of the
transactions contemplated hereby and by the Other Reorganization Agreements have
been duly authorized by LISN. This Agreement constitutes a valid and binding
obligation of LISN, enforceable in accordance with its terms, and all Other

and instruments contemplated hereby and thereby to which LISN is a party, the
consummation of the transactions contemplated by this Agreement and the Other

or governmental body or agency pursuant to, LISN's articles of incorporation or
Code of Regulations, any of its Subsidiaries' charter or Code of Regulations or
bylaws, or any law, statute, rule or regulation to which LISN or any of its
Subsidiaries is subject, or any agreement, instrument, order, judgment or decree
to which LISN or any of its Subsidiaries is subject, except in such cases in
which the failure to obtain any such authorization, consent, approval, exemption
or to provide such notice or make such filing could not reasonably be expected
to have a Material Adverse Effect (it being understood and agreed that this
exception does not apply to any representation as to any contract, agreement or
document required to be listed on the attached LISN Contracts Schedule). Neither
LISN, any of its Subsidiaries nor any of the LISN Shareholders is a party to or
bound by any written or, to the Knowledge of LISN, oral agreement or
understanding with respect to an LISN Transaction other than this Agreement and
the other agreements contemplated hereby. Neither LISN, nor to LISN's Knowledge,
HIG has breached any of its respective obligations pursuant to the Exclusivity
Agreement.

agreement or instrument to which LISN or any of its Subsidiaries is subject;
except as set forth on the attached LISN Contracts Schedule, neither LISN nor or
any of its Subsidiaries has any present expectation or intention of not fully
performing on a timely basis all such obligations required to be performed by
LISN or such Subsidiary under any contract, agreement or instrument to which
LISN or such Subsidiary is subject; and neither LISN nor or any of its
Subsidiaries has any Knowledge of any breach or cancellation or anticipated
cancellation by the other parties to any contract, agreement, instrument or
commitment to which it is a party. Neither LISN nor any of its Subsidiaries is a
party to any contract, agreement or commitment the performance of which could
reasonably be expected to have a Material Adverse Effect.

                  (iv) LISN has made available to Orius' Shareholder
Representative's special counsel a true and correct copy of each of the written
instruments, plans, contracts and agreements and an accurate description of each

                  (i) The attached LISN Intellectual Property Schedule contains

subject Intellectual Property Rights. Each of LISN and its Subsidiaries owns and
possesses all right, title and interest to, or has the right to use pursuant to
a valid and enforceable license, all Intellectual Property Rights necessary for
the operation of its business, free and clear of all Liens other than Existing
Bank Liens. Except as set forth on the attached LISN Intellectual Property
Schedule, the loss or expiration of any Intellectual Property Right or related
group of Intellectual Property Rights owned or used by LISN or any of its
Subsidiaries has not had

and would not reasonably be expected to have a Material Adverse Effect, and no
loss or expiration of any Intellectual Property Right is threatened, pending or,
to LISN's Knowledge, reasonably foreseeable. Each of LISN and its Subsidiaries
has taken commercially reasonable steps to maintain and protect the Intellectual
Property Rights which it owns.

                  (ii) Except as set forth on the attached LISN Intellectual
Property Schedule, (a) there have been no claims made against LISN or any of its
Subsidiaries asserting the invalidity, misuse or unenforceability of any of the
Intellectual Property Rights owned or used by LISN or any of its Subsidiaries
and, to LISN's Knowledge, there is no basis for any such claim, (b) neither LISN
nor any of its Subsidiaries has received any written notices of, and to LISN's
Knowledge neither LISN nor any of its Subsidiaries has received any unwritten
notice of, and has no Knowledge of, any facts which indicate a likelihood of,
any infringement or misappropriation by, or conflict with, any third party with
respect to any Intellectual Property Rights (including any demand or request
that LISN or any of its Subsidiaries license any rights from a third party), (c)
to LISN's Knowledge the conduct of LISN's and its Subsidiaries' businesses has
not infringed, misappropriated or conflicted with and does not infringe,
misappropriate or conflict with any Intellectual Property Rights of other
Persons, and (d) to LISN's Knowledge, the Intellectual Property Rights owned by
or licensed to LISN or any of its Subsidiaries have not been infringed,
misappropriated or conflicted by other Persons. The transactions contemplated by
this Agreement will have no Material Adverse Effect on LISN's and its
Subsidiaries' right, title or interest in and to the Intellectual Property
Rights listed on the LISN Intellectual Property Schedule, and all of such
Intellectual Property Rights shall be owned or available for use by LISN and its
Subsidiaries on terms and conditions immediately after the Closing which are
substantially identical to those in effect prior to Closing.

                  6P. Litigation, etc. Except as set forth on the attached LISN
Litigation Schedule, there are no, and since the date of acquisition of LISN by
Willis Stein there have not been any, actions, suits, proceedings (including any
arbitration proceedings), orders, investigations or claims pending or, to LISN's
Knowledge, threatened against or any material actions, suits, proceedings
(including any arbitration proceedings), orders, investigations or claims
affecting LISN or any of its Subsidiaries (or to LISN's Knowledge, pending or
threatened against or any actions, suits, proceedings (including any arbitration
proceedings), orders, investigations or claims affecting any of the officers,
directors or employees of LISN with respect to its business activities), or
pending or threatened by LISN or any of its Subsidiaries against any Person, at
law or in equity, or before or by any governmental department, commission,
board, bureau, agency or instrumentality (including any actions, suits,
proceedings or investigations with respect to the transactions contemplated by
this Agreement); neither LISN nor any of its Subsidiaries is subject to any
arbitration proceedings under collective bargaining agreements or otherwise or
any governmental investigations or inquiries; and, to LISN's Knowledge, there is
no basis for any of the foregoing. The foregoing includes, without limitation,
actions pending or threatened involving the prior employment of any of the 35
most highly compensated employees of LISN and its Subsidiaries on a consolidated
basis, their use in connection with LISN's or any of its Subsidiaries'
businesses of any information or techniques allegedly proprietary to any of
their former employers or their obligations under any agreements with prior
employers. Except as set forth on the attached LISN Litigation Schedule, LISN is
fully insured with respect to each of the matters set forth on the attached LISN
Litigation Schedule, and neither LISN nor any of its Subsidiaries is subject to
any judgment, order or decree of any court or other

governmental agency, and neither LISN nor any of its Subsidiaries has received
any opinion or memorandum or advice from legal counsel to the effect that it is
exposed, from a legal standpoint, to any liability which could have a Material
Adverse Effect.

                  6Q. Brokerage. Except for the obligations stated on the
attached LISN Contracts Schedule, there are and shall be no claims for brokerage
commissions, finders' fees or similar compensation in connection with the
transactions contemplated by this Agreement based on any arrangement or
agreement to which LISN or any of its Subsidiaries is a party or to which LISN
or any of its Subsidiaries is subject, it being acknowledged and agreed that any
such brokerage commissions, finder's fees or similar compensation shall be
deemed to be Indebtedness of LISN for purposes of this Agreement.

                  6R. Insurance. The attached LISN Insurance Schedule contains a
description of each insurance policy maintained by LISN and any of its
Subsidiaries with respect to its and any of its Subsidiaries' properties, assets
and business, together with a statement of the aggregate amount of claims paid
out, and claims pending, under each such insurance policy or other arrangement
through the date hereof. All such policies are in full force and effect as of
the Closing, all premiums due thereon have been paid, and LISN and its
Subsidiaries are otherwise in compliance in all material respects with the terms
and provisions of such policies. Neither LISN nor any of its Subsidiaries is in
default with respect to its obligations under any insurance policy maintained by
it, and neither LISN nor any of its Subsidiaries has received any notice of
cancellation or non-renewal of any such policy or arrangement nor is the
termination of any such policies or arrangements threatened. Neither LISN nor
any of its Subsidiaries has ever been denied insurance coverage, and there is no
claim pending under any policies or arrangements as to which coverage has been
questioned, denied or disputed by the underwriters of such policies or
arrangements. Neither LISN nor any of its Subsidiaries has received any notice
from any of its insurance carriers that any insurance premiums will be increased
in the future or that any insurance coverage presently provided for will not be
available to LISN or any of its Subsidiaries in the future on substantially the
same terms as now in effect and none of such policies or arrangements provides
for any retrospective premium adjustment, experienced-based liability or loss
sharing arrangement affecting LISN or any of its Subsidiaries. A true and
complete list of all outstanding claims for medical expenses in excess of
$10,000 made by or with respect to any single employee of LISN or any of its
Subsidiaries is set forth in the LISN Insurance Schedule. Except as set forth on
the attached LISN Insurance Schedule, LISN has no self-insurance or co-insurance
programs, and the reserves set forth on the LISN Latest Balance Sheet are
adequate to cover all anticipated Liabilities with respect to any such
self-insurance or co-insurance programs.

                  6S. Employees. To LISN's Knowledge, no executive or key
employee of LISN or any of its Subsidiaries and no group of employees of LISN or
any of its Subsidiaries has any plans to terminate employment with LISN or such
Subsidiary. LISN has no material labor relations problems (including any union
organization activities, threatened or actual strikes or work stoppages or
material grievances). None of LISN, the LISN Shareholders nor, to LISN's
Knowledge, any of its other employees or consultants are subject to any
noncompete, nondisclosure, confidentiality, employment, consulting or other
agreement or judgment, decree or order of any court or administrative agency,
relating to, affecting or in conflict with the present or proposed business

activities of LISN and its Subsidiaries or such Person's duties to LISN and its
Subsidiaries, except for agreements between LISN and its present and former
employees. LISN has not received any written notice alleging that any violation
of any such agreements has occurred, and to LISN's Knowledge neither LISN nor
any of its Subsidiaries has received any unwritten notice thereof. The LISN
Employees Schedule attached hereto contains a correct and complete list of all
employees and consultants of LISN which have executed and delivered to LISN any
agreement providing for the nondisclosure by such Person of any confidential
information of LISN.

                  6T. ERISA.

                  (i) Except as set forth on the attached LISN Employee Benefits
Schedule, LISN does not have any obligation to contribute to (or any other
liability, including current or potential withdrawal liability, with respect to)
any "multi-employer plan" (as defined in Section 3(37) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")).

                  (ii) LISN does not maintain or have any obligation to
contribute to (or any other liability with respect to) any plan or arrangement,
whether or not terminated, which provides medical, health, life insurance or
other welfare-type benefits for current or future retired or terminated
employees or any dependents of such employees (except for limited continued
medical benefit coverage required to be provided under Section 4980B of the Code
("COBRA") or as required under applicable state law).

                  (iii) LISN does not maintain, contribute to or have any actual
or potential liability under (or with respect to) any employee plan which is a
"defined benefit plan" (as defined in Section 3(35) of ERISA).

                  (iv) Except as set forth on the attached LISN Employee
Benefits Schedule, LISN does not maintain, contribute to or have any actual or
potential liability under (or with respect to) any employee plan which is a
"defined contribution plan" (as defined in Section 3(34) of ERISA) (the
"Plans"), whether or not terminated.

                  (v) Except as set forth on the attached LISN Employee Benefits
Schedule under the heading "Other Plans" (the "Other Plans"), LISN does not
maintain, contribute to or have any actual or potential liability under (or with
respect to) any plan or arrangement providing benefits or remuneration to
current or former employees or independent contractors, including any employment
contract, bonus or incentive plan, plan for deferred compensation, employee
health or other welfare benefit plan, severance arrangement or other material
policy, program or arrangement, whether or not terminated. The attached LISN
Employee Benefits Schedule sets forth the aggregate amount of bonuses and other
incentive compensation reasonably expected to be paid by LISN for the fiscal
year ending December 31, 1999.

                  (vi) With respect to the Plans set forth on the attached LISN
Employee Benefits Schedule, all required payments, premiums, contributions,
reimbursements or accruals for all periods ending prior to or as of the Closing
Date shall have been made or properly accrued. None of the Plans has any
material unfunded liabilities which are not reflected on the Latest Balance
Sheet.

<PAGE>   71

                  (vii) Except as set forth on the attached LISN Employee
Benefits Schedule, the Plans and all related trusts, insurance contracts and
funds have been maintained, funded and administered in compliance in all
material respects with the applicable provisions of ERISA, the Code and other
applicable laws. Except as set forth on the attached LISN Employee Benefits
Schedule, LISN has timely complied with all reporting and disclosure obligations
as they apply to the Plans, and LISN has complied with the requirements of
COBRA. To LISN's Knowledge, none of LISN or any trustee or administrator of any
Plan has engaged in any transaction with respect to the Plans which would
subject LISN or any trustee or administrator of the Plans, or any party dealing
with any such Plan, nor do the transactions contemplated by this Agreement
constitute transactions which would subject any such party, to either a civil
penalty assessed pursuant to Part 502(i) of ERISA, or any other penalty or
excise tax or the tax or penalty on prohibited transactions imposed by Section
4975 of the Code or any other penalty or excise tax. No actions, suits or claims
with respect to the assets of the Plans (other than routine claims for benefits)
are pending or, to LISN's Knowledge, threatened which could result in or subject
LISN to any liability and there are no circumstances which would give rise to or
be expected to give rise to any such actions, suits or claims.

                  (viii) The attached LISN Employee Benefits Schedule sets forth
whether or not a favorable determination letter from the Internal Revenue
Service has been received by LISN with respect to each Plan that it is qualified
under Section 401(a) of the Code (including requirements imposed by the Tax
Reform Act of 1986 and subsequent legislation), and, to LISN's Knowledge, there
are no circumstances which would cause a Plan to lose such qualified status.

                  (ix) For purposes of this Section 6T, "LISN" shall be deemed
to include all organizations under common control with LISN pursuant to Section
414 of the Code.

                  6U. Compliance with Laws; Permits; Certain Operations. Except
as set forth on the attached LISN Compliance Schedule:

compliance with and, throughout the immediately preceding 5 year period has
complied in all material respects with, all applicable laws, ordinances, codes,
rules, requirements and regulations of foreign, federal, state and local
governments and all agencies thereof relating to the operation of its business
and the maintenance and operation of its properties and assets. During the five
year period ending on the Closing Date, no written (or, to LISN's Knowledge,
oral) notices have been received by and no claims have been filed against LISN
or any of its Subsidiaries alleging a violation of any such laws, ordinances,
codes, rules, requirements or regulations.

                  (ii) Each of LISN and its Subsidiaries holds and is in
compliance with all permits, licenses, bonds, approvals, certificates,
registrations, accreditations and other authorizations of all foreign, federal,
state and local governmental agencies required for the conduct of its business
and the ownership of its properties (including as the same relate to
Environmental and Safety Requirements), and the attached LISN Permits Schedule
sets forth a description of all of such material permits, licenses, bonds,
approvals, certificates, registrations, accreditations and other authorizations.

Subsidiaries alleging the failure to hold any of the foregoing. All of such
permits, licenses, bonds, approvals, accreditations, certificates, registrations
and authorizations will be available for use by LISN and its Subsidiaries, as
the case may be, immediately after the Closing.

                  6V. Environmental and Safety Matters.

         all material respects with and is in material compliance with all
         Environmental and Safety Requirements. Neither LISN nor any of its
         Subsidiaries have received any written or oral notice, report or
         information regarding any actual or alleged violation of Environmental
         and Safety Requirements or any liabilities or potential liabilities
         relating to it or its facilities arising under Environmental and Safety
         Requirements.

                           (b) Neither this Agreement nor the consummation of
         the transactions contemplated hereby will result in any obligations for
         site investigation or cleanup, or notification to or consent of any
         government agencies or third parties under any Environmental and Safety
         Requirements (including any so called "transaction-triggered" or
         "responsible property transfer" laws and regulations).

                           (c) None of the following exists at any property or

                                            other disposal areas.

         treated, stored, disposed of, arranged for or permitted the disposal
         of, transported, handled or Released any substance (including any
         hazardous substance) or owned, occupied or operated any facility or
         property (and no such property or facility is contaminated by any such
         substance) in a manner that has given or could give rise to any
         Liabilities (including any Liability for response costs, corrective
         action costs, personal injury, natural resource damages, property
         damage or attorneys fees or any investigative, corrective or remedial
         obligations) pursuant to CERCLA or any other Environmental and Safety
         Requirements.

                           (e) Neither LISN nor any of its Subsidiaries has,
         either expressly or by operation of law, assumed or undertaken any
         liability or corrective, investigatory or remedial obligation of any
         other Person relating to any Environmental and Safety Requirements.

to LISN's Knowledge, neither LISN nor any of its Subsidiaries has any reason to
believe that, such supplier will stop, materially decrease the rate of, or
materially change the terms (whether related to payment, price or otherwise)

its Subsidiaries has received any indication from any material customer of LISN

                  and storm sewer, all of which services are adequate in
                  accordance with all applicable laws, ordinances, rules and
                  regulations and are provided via public roads or via
                  permanent, irrevocable, appurtenant easements benefitting the
                  parcel of LISN Owned Real Property; and

                           (i) each parcel of LISN Owned Real Property abuts on
                  and has direct vehicular access to a public road, or has
                  access to a public road via a permanent, irrevocable,
                  appurtenant easement benefitting the parcel of real property,
                  and access to the property is provided by paved public
                  right-of-way with adequate curb cuts available.

                  (ii) The LISN Real Property Schedule attached hereto sets
forth a list of all of the leases, subleases and licenses ("LISN Leases") of
real property (the "Leased Real Property"), including the address of the LISN
Leased Real Property, in which LISN or any of its Subsidiaries has a leasehold,
subleasehold or licensed interest, other than any lease which may terminated by




                                      -66-

either party without liability to the other on less than 90 days notice or
involving aggregate annual rentals of less than $50,000, not otherwise involving
any material liability and the termination of which would not have a Material
Adverse Effect. LISN or such Subsidiary holds a valid and existing leasehold,
subleasehold or license interest under each of the LISN Leases. With respect to
each LISN Lease listed on the attached LISN Real Property Schedule, neither
LISN, any of its Subsidiaries, nor, to the Knowledge of LISN, any other party to
the LISN Lease is in breach or default under the LISN Lease, and no event has
occurred or circumstance exists which, with the delivery of notice, passage of
time or both, would constitute such a breach or default or permit the
termination, modification, or acceleration of rent under the LISN lease, there
are no disputes, oral agreements, or forbearance programs in effect as to such
LISN Lease and neither LISN nor any of its Subsidiaries has assigned,
transferred, conveyed, mortgaged, deeded in trust or encumbered any interest in
the LISN Lease. Except for the LISN Leased Real Property, and the LISN Owned
Real Property, there is no real property which is leased or otherwise used in
LISN's business.

                  6Z. Regulatory Status. Since its date of incorporation,
neither LISN nor any of its Subsidiaries has been, and as of the Closing Date
shall not be, a "United States real property holding corporation," as defined in
Section 897(c)(2) of the Code and in Section 1.897-2(b) of the Treasury
Regulations issued thereunder. Neither LISN nor any of its Subsidiaries is an
"investment company" or an "affiliated person" of, or "promoter" or "principal
underwriter" for, an "investment company," as such terms are defined under the
Investment Orius Act of 1940, as amended. Neither LISN nor any of its
Subsidiaries is subject to any law which regulates the incurring of Indebtedness
by LISN or such Subsidiary, including any laws relating to common contract
carriers or the sale of electricity, gas, steam, water or other public utility
services.

                  6AA. Disclosure. Neither this Agreement nor any of the
Schedules attached hereto nor any of the written statements, certificates or
other items prepared and delivered to LISN, the LISN Shareholders or the
Investors by or on behalf of LISN or the LISN Shareholders upon execution of
this Agreement or any of the agreements contemplated hereby or to induce the
consummation of any of the transactions contemplated hereby or thereby, when
taken together as a whole, contain any untrue statement of a material fact or
omit a material fact necessary to make the statements contained herein or
therein, in light of the circumstances in which they were made, not misleading.
There is no fact which LISN has not disclosed to executive officers of Orius (or
executive officers of its predecessor) in writing and of which any of its
officers, directors or executive employees is aware which has had or would
reasonably be expected to have a Material Adverse Effect.

                  6BB. Closing Date. The representations and warranties of LISN
contained in this Section 6 and elsewhere in this Agreement and all information
contained in any Exhibit, Schedule or attachment hereto or in any certificate or
other writing delivered by, or on behalf of, LISN to the Orius Stockholders
Representative pursuant to this Agreement shall be true and correct on the
Closing Date as though then made and as though the Closing Date was substituted
for the date of this Agreement throughout such representations and warranties,
except in any case in which a representation and warranty expressly refers to a
different date, in which case such representation and warranty shall be true and
correct as of such date.

                  Section 7. Indemnification and Certain Other Agreements.

                  7A. Survival of Representations and Warranties. The
representations and warranties in this Agreement and the Schedules attached
hereto, or in any of the written statements, certificates or other items
prepared and delivered to LISN, the LISN Shareholders or the Investors by or on
behalf of Orius or the Orius Stockholders, or to Orius or the Orius Stockholders
by or on behalf of LISN or the LISN Shareholders upon execution of this
Agreement or any of the agreements contemplated hereby or to induce the
consummation of any of the transactions contemplated hereby or thereby, hereby
shall survive the Closing as follows:

                  (i) the representations and warranties in any of Section 5M
and Section 6M (Tax Matters), Section 5T and Section 6T (ERISA) shall terminate
sixty (60) days after the date as of which the applicable statutes of
limitations with respect to the liabilities in question expire (after giving
effect to any extensions or waivers thereof);

                  (ii) the representation and warranties in Section 5V and
Section 6V (Environmental and Safety Matters) shall terminate on the sixth
anniversary of the Closing Date.

                  (iii) the representations and warranties in Section 5U and
Section 6U (Compliance with Laws; Permits; Certain Operations) shall terminate
on the fourth anniversary of the Closing Date;

                  (iv) none of the representations and warranties in any of
Section 5B or Section 6B (Capital Stock and Related Matters), Section 5Q or
Section 6Q (Brokerage), the first and second sentences of Section 5D or Section
6D (Authorization; No Breach), or in any of the Orius Joinder Agreements or the
LISN Transmittal Letters shall terminate; and

                  (v) all other representations and warranties in this Agreement
and the Schedules attached hereto, or in any of the written statements,
certificates or other items prepared and delivered to LISN, the LISN
Shareholders or the Investors by or on behalf of Orius or the Orius
Stockholders, or to Orius or the Orius Stockholders by or on behalf of LISN or
the LISN Shareholders upon execution of this Agreement or any of the agreements
contemplated hereby or to induce the consummation of any of the transactions
contemplated hereby or thereby, shall terminate upon termination of the eighteen
month period commencing on the Closing Date; provided that any representation or
warranty in respect of which indemnity may be sought under Section 7B, and the
indemnity with respect thereto, shall survive the time at which it would
otherwise terminate pursuant to this Section 7A if written notice of the breach
or potential breach thereof giving rise to such right or potential right of
indemnity shall have been given to the Party against whom such indemnity may be
sought prior to such time. The representations and warranties in this Agreement
and the Schedules and Exhibits attached hereto or in any writing delivered in
connection with this Agreement shall survive for the periods set forth in this
Section 7A and shall in no event be affected by any investigation, inquiry or
examination made for or on behalf of any Party, any Representative or any
Investor, or the knowledge of any officer, director, shareholder, employee,
partner or agent of any of the foregoing or the acceptance by any of the
foregoing of any certificate or opinion hereunder. Without limiting the
foregoing, in no event will any disclosure pursuant to Section 4I



                                      -68-


<PAGE>   77

or otherwise prior to the Closing serve to amend any representation or warranty
for any purpose of this Agreement, except and solely to the extent that the
notifying party (i) promptly upon discovery thereof notifies each other party to
this Agreement in reasonably detail of the facts and circumstances which would
cause the notifying party to be in breach of a representation or warranty as of
the Closing, and (ii) in connection with any dispute relating thereto carries
the burden of proving that such notifying party was not in breach of such
representation and warranty upon execution of this Agreement, in which event the
disclosure thereof in writing prior to the Closing shall, solely for purposes of
Section 7, be deemed to amend the representations and warranties identified in
such notice.

                  7B. General Indemnification.

                  (i) Indemnification by the Orius Indemnifying Stockholders.
Subject to the limitations set forth in this Section, the Orius Stockholders
(other than HIG and the Orius Warrantholders) (the "Orius Indemnifying
Stockholders") shall jointly and severally indemnify Orius, the Investors and
the LISN Shareholders and their respective Affiliates, partners, officers,
directors, employees, agents, representatives, successors and permitted assigns
(collectively, the "LISN Parties" and each individually a "LISN Party"), and
save and hold each of them harmless against as and when incurred for any and all
loss, liability, demand, claim, action, cause of action, cost, damage,
deficiency, Tax, penalty, fine or expense, whether or not arising out of third
party claims (including interest, penalties, reasonable attorneys' fees and
expenses and all amounts paid in investigation, defense or settlement of any of
the foregoing) (collectively, "Losses") which any of them may suffer, sustain or
become subject to, as a result of, in connection with, relating or incidental to
or by virtue of: (a) any breach of any representation or warranty of Orius under
this Agreement or any of the Schedules attached hereto, or in any of the written
statements, certificates or other items prepared and delivered to LISN, the LISN
Shareholders or the Investors by or on behalf of Orius or the Orius
Stockholders, upon execution of this Agreement or any of the agreements
contemplated hereby or after the date hereof and at or prior to Closing to
induce the consummation of any of the transactions contemplated hereby or
thereby; (b) any nonfulfillment or breach of any covenant, agreement or other
provision by Orius under this Agreement or any of the Schedules and Exhibits
attached hereto required to be performed or complied with by Orius at or prior
to the Closing (except to the extent waived in writing in accordance with the
terms hereof or thereof, as applicable); (c) any inaccuracy or breach of any
representation or warranty included in any Joinder Agreement, any Orius Call
Agreement or any Orius Put Agreement of which Orius had Knowledge at or prior to
the Closing, or (d) any of the matters set forth on the Orius Indemnification
Schedule attached hereto; provided that the Orius Indemnifying Stockholders
shall not have any liability under clause (a) above (other than with respect to
the representations and warranties contained in Section 5B, Section 5Q, and the
first and second sentences of Section 5D) unless the aggregate of all Losses
relating thereto for which the Orius Stockholders would, but for this proviso,
be liable exceeds $1,500,000 (the "Orius Deductible"), in which event the Orius
Indemnifying Stockholders shall be liable under clause (a) above only to the
extent that the aggregate of all Losses arising thereunder exceeds the Orius
Deductible; provided further that the Orius Indemnifying Stockholders shall not
be liable in respect of any particular Loss under clause (a) above unless the
amount thereof, individually or collectively with all Losses arising from the
same or related events or circumstances, is equal to or greater than $25,000
(the "Orius Basket"), in which event the Orius



                                      -69-



<PAGE>   78

Indemnifying Stockholders will be liable for the full amount of each such Loss
(subject to the Orius Deductible and the Orius Cap); provided further that the
aggregate liability of any Orius Indemnifying Stockholder pursuant to this
Section 7B shall in no event exceed the product of the Orius Common Value Per
Share multiplied by the aggregate number of shares of Orius Common Stock held by
such Person on the date hereof as reflected on the Orius Stockholders Schedule
attached hereto; and provided further that the aggregate liability of the Orius
Indemnifying Stockholders under clause (a) above (other than with respect to the
representations and warranties contained in Section 5B, Section 5Q, and the
first and second sentences of Section 5D) shall in no event exceed $80,000,000
(the "Orius Cap"), it being understood, however, that nothing in this Agreement
(including this Section 7B) shall limit or restrict the right of any of Orius,
the Investors and the LISN Parties to maintain or recover any amounts in
connection with any action or claim based upon fraudulent misrepresentation or
deceit.

                  (ii) Indemnification by the LISN Shareholders. Subject to the
limitations set forth in this Section, the LISN Shareholders shall jointly and
severally indemnify Orius, the Investors and each of the Orius Stockholders and
their respective Affiliates, partners, officers, directors, employees, agents,
representatives, successors and permitted assigns (collectively, the "Orius
Parties" and each individually an "Orius Party"), and save and hold each of them
harmless against as and when incurred for any Losses which any of them may
suffer, sustain or become subject to, as a result of, in connection with,
relating or incidental to or by virtue of: (a) any breach of any representation
or warranty of LISN under this Agreement or any of the Schedules attached
hereto, or in any of the written statements, certificates or other items
prepared and delivered to Orius or the Orius Stockholders by or on behalf of
LISN or the LISN Shareholders upon execution of this Agreement or any of the
agreements contemplated hereby or after the date hereof and at or prior to
Closing to induce the consummation of any of the transactions contemplated
hereby or thereby; (b) any nonfulfillment or breach of any covenant, agreement
or other provision by LISN under this Agreement or any of the Schedules and
Exhibits attached hereto required to be performed or complied with by LISN at or
prior to the Closing (except to the extent waived in writing in accordance with
the terms hereof or thereof, as applicable); (c) any inaccuracy or breach of any
representation or warranty included in the Note Exchange Agreement of which LISN
had Knowledge at or prior to the Closing; or (d) any of the matters set forth on
the LISN Indemnification Schedule attached hereto; provided that the LISN
Shareholders shall not have any liability under clause (a) above (other than
with respect to the representations and warranties contained in Section 6B,
Section 6Q, and the first and second sentences of Section 6D) unless the
aggregate of all Losses relating thereto for which the LISN Shareholders would,
but for this proviso, be liable exceeds $785,000 (the "LISN Deductible""), in
which event the LISN Shareholders shall be liable under clause (a) above only to
the extent that the aggregate of all Losses arising thereunder exceeds the LISN
Deductible; provided further that the LISN Shareholders shall not be liable in
respect of any particular Loss under clause (a) above unless the amount thereof,
individually or collectively with all Losses arising from the same or related
events or circumstances, is equal to or greater than $25,000 (the "LISN
Basket"), in which event the LISN Shareholders will be liable for the full
amount of each such Loss (subject to the LISN Deductible and the LISN Cap);
provided further that the aggregate liability of any LISN Shareholder pursuant
to this Section 7B shall in no event exceed the product of (x) the number of
shares of LISN Common held by such LISN Shareholder as of the date hereof, as
set forth on the LISN Shareholders Schedule attached hereto, multiplied by (y)
the


                                      -70-



<PAGE>   79

quotient of the Closing LISN Investor Value divided by the aggregate number of
shares of LISN Common outstanding as of the date hereof, as set forth on the
LISN Shareholders Schedule attached hereto; provided further that the aggregate
liability of the LISN Shareholders under clause (a) above (other than with
respect to the representations and warranties contained in Section 6B, Section
6Q, and the first and second sentences of Section 6D) shall in no event exceed
$41,800,000 (the "LISN Cap"), it being understood, however, that nothing in this
Agreement (including this Section 7B) shall limit or restrict the right of any
of Orius, the Investors and the Orius Parties to maintain or recover any amounts
in connection with any action or claim based upon fraudulent misrepresentation
or deceit.

                  (iii) Exclusive Remedy; Other Matters; Purchase Price
Adjustment.

                           (a) Exclusive Remedy. Effective upon consummation of
         the LISN Merger and the other transactions contemplated by this
         Agreement to be consummated contemporaneously therewith or prior
         thereto, the sole and exclusive remedy for Losses suffered by Orius,
         the Investors, any Orius Party or any LISN Party arising from or
         relating to this Agreement or the transactions contemplated hereby,
         other than for fraudulent misrepresentation or deceit, shall be
         pursuant to this Section 7B.

                           (b) Payments. For purposes of this Agreement, each
         Person entitled to indemnification pursuant to this Section 7 shall be
         referred to herein as an "Indemnitee" and each Person obligated to
         provide indemnification pursuant to this Section 7 shall be referred to
         herein as an "Indemnitor". Subject to Section 7B(iii)(e) below, each
         Indemnitor shall pay to each Indemnitee the amount so claimed in
         immediately available funds promptly or an adjustment to securities as
         contemplated by subsection (e) below after the Indemnitee provides the
         Indemnitor with written notice of a claim hereunder unless the
         Indemnitor in good faith disputes such claim. If the Indemnitor
         disputes such claim in good faith, then promptly after the resolution
         of such dispute pursuant to the provisions thereof, the amount finally
         determined to be due shall be paid by the Indemnitor to the Indemnitee
         in immediately available funds (subject to Section 7B(iii)(e) below).

                           (c) Insurance and Other Indemnity Recoveries. The
         amount of any Loss shall be reduced for purposes of this Section 7B by
         the insurance proceeds actually received by the Indemnitee with respect
         to such Loss, and by the proceeds actually received by the Indemnitee
         pursuant to any other indemnity rights in respect of such Loss, net of
         the costs incurred by the Indemnitee in connection with collecting such
         proceeds; provided that such proceeds shall be disregarded in any
         calculation of Losses for purposes of determining whether Losses are
         equal to or greater than the Orius Deductible, LISN Deductible, Orius
         Basket or LISN Basket. Orius and LISN will use reasonable efforts to
         collect proceeds from insurance policies in respect of, and from
         parties obligated under contractual indemnity agreements to indemnify
         Orius or LISN, respectively, against, Losses for which the Orius
         Indemnifying Stockholders or the LISN Shareholders would otherwise be
         liable hereunder; provided that availability of recovery from such
         other sources will not be a defense to indemnity obligations under this
         Agreement.

                           (d) Purchase Price Adjustment. Amounts paid to or on
         behalf of the Orius Stockholders, the LISN Shareholders or the
         Investors as indemnification shall be treated as adjustments to the
         consideration paid in the LISN Merger and the other transactions
         contemplated hereby, as applicable.

                           (e) Consideration Payable to LISN Shareholders and
         the Investors. Notwithstanding any other provision hereof,
         indemnification payments to LISN Shareholders and Investors pursuant to
         this Agreement shall be made solely in Orius Common and Series C
         Participating Preferred Stock and shall in no event be payable in cash,
         notes or other property. If any LISN Shareholder or Investor is
         entitled to an indemnity payment hereunder, each Indemnitor in respect
         thereof shall either (x) deliver to such LISN Shareholder such shares
         of Orius stock as the LISN Shareholder may request, or (y) pay to Orius
         the amount owing to the LISN Shareholder. If an Indemnitor elects to
         make payment in accordance with clause (y) foregoing, Orius will, upon
         receipt thereof, promptly issue to such LISN Shareholder shares of
         Orius Common and Series C Participating Preferred Stock (as directed by
         such LISN Shareholder) with Fair Market Value equal to such amount
         received by Orius from the Indemnitor.

                           (f) Indemnity Payments to or on Behalf of Orius.
         Notwithstanding the foregoing, if payments are made by or on behalf of
         the Orius Indemnifying Stockholders to or on behalf of Orius in respect
         of any of the matters described in clauses (a) through (d) of Section
         7B(i) (an "Orius Breach") in each case in amounts and in a manner such
         that the Losses suffered by the LISN Shareholders and the Investors are
         fully compensated as a result thereof, then neither the LISN
         Shareholders nor the Investors shall have any right to further
         indemnity against the Orius Indemnifying Stockholders in respect of
         such Orius Breach. Also, notwithstanding the foregoing, if payments are
         made by or on behalf of the LISN Shareholders to or on behalf of Orius
         or LISN in respect of any of the matters described in clauses (a)
         through (d) of Section 7B(ii) (a "LISN Breach") in each case in amounts
         and in a manner such that the Losses suffered by the Orius Stockholders
         and the Investors are fully compensated as a result thereof, then
         neither the Orius Stockholders nor the Investors shall have any right
         to further indemnity against the LISN Shareholders in respect of such
         LISN Breach.

                  7C. Right to Offset Indemnity Obligations Against Outstanding
Securities.

                  (i) Offset Rights Generally. If any Indemnitor fails to comply
with its obligations pursuant to Section 7B (a "Breaching Indemnitor" and,
collectively with all Indemnitors who have failed to comply with such
obligations in respect of the same Loss, the "Breaching Indemnitors") to make
cash payments to an Indemnitee in an aggregate amount sufficient to reimburse
the Indemnitee for all Losses or adjustments to securities as required pursuant
to Section 7B (the portion of such Losses in respect of which the Indemnitee has
not received cash payment from the Breaching Indemnitor, the "Unreimbursed
Loss"), the Indemnitee may pursue any and all rights and remedies against each
of the Breaching Indemnitors available in law or in equity, subject only to the
limitations set forth in Section 7B above. In addition, and not in limitation of
or in substitution for the foregoing, upon the request of the Indemnitee, Orius
will cancel shares of the Orius Common


                                      -72-
<PAGE>   81

retained by such Breaching Indemnitors upon consummation of the transactions
described in Section 1B(iv), or shares of Series C Participating Preferred
and/or Orius Junior Notes issued to or held by each or any of such Breaching
Indemnitors pursuant to Section 1B(v) or pursuant to any of Orius Put Agreements
or Orius Call Agreements, so long as the aggregate Fair Market Value of such
canceled securities does not exceed the amount of such indemnity obligations,
and reissue to the Indemnitee shares of each class of stock so canceled in the
amount for each such class which was canceled, and/or Orius Junior Notes in the
aggregate principal amount of, plus accrued and unpaid interest on, Orius Junior
Notes so canceled. To effect any such election, the Indemnitee shall deliver to
Orius and each of the Representatives a written notice (a "Cancellation Notice")
(a) identifying the Breaching Indemnitors and stating that such Breaching
Indemnitors have failed to make payments to such Indemnitee in respect of a Loss
in the full amount required pursuant to Section 7B, (b) the amount of such
Unreimbursed Loss, (c) if the Indemnitee desires to cancel any shares of Orius
Common or shares of Series C Participating Preferred in satisfaction of such
Unpaid Loss, such Indemnitee's estimate of the Fair Market Value of one share of
Orius Common and of the Fair Market Value of one share of Series C Participating
Preferred, and (d) the number of shares of Orius Common and shares of Series C
Participating Preferred, and the aggregate principal amount of Orius Junior
Notes which the Indemnitee has elected to cause Orius to cancel in satisfaction
of such Orius Unpaid Loss (the "Canceled Securities"). The Indemnitee may
designate for cancellation from each Breaching Indemnitor (and/or its
transferee) such numbers of shares of Orius Common and/or shares of Series C
Participating Preferred, and/or Orius Junior Notes in such principal amount, as
it may determine in its sole discretion, so long as the aggregate Fair Market
Value of such Canceled Securities does not exceed the aggregate Unreimbursed
Loss at the time of delivery of the applicable Cancellation Notice to the
Representatives. Upon request by any Indemnitee, Orius will provide to such
Indemnitee a list of all certificates representing Orius Common, shares of
Series C Participating Preferred and Orius Junior Notes issued to the Breaching
Indemnitors at the Closing or otherwise held by the Breaching Indemnitors, which
list shall state the name of the Person to whom such securities were issued at
the Closing, the name of the holder of such securities as reflected on Orius's
books and records as of the date of such notice, the amount of each class and
type of such securities then held by each such holder, and the number(s) (or
other identifying characteristics) of the certificates representing such
securities. Upon delivery of a Cancellation Notice by an Indemnitee to Orius and
the Representatives, the securities identified in such notice as Canceled
Securities shall be deemed for all purposes to be canceled and, accordingly,
Orius's books and records shall thereafter reflect that such securities are no
longer outstanding for any purpose, unless within 15 days following the delivery
thereof either the Persons identified in such Cancellation Notice or the
Representative thereof delivers a written notice to each of Orius, the
Representatives and the Indemnitee objecting thereto, in which event such
securities shall not be canceled but shall be held by such Persons, and such
Persons shall (and Orius shall use reasonable efforts to) ensure that no
interest therein will be transferred, pending resolution of the dispute. Each
party to such a dispute shall seek to resolve such dispute expeditiously and in
good faith. If and at such time as any securities are canceled pursuant to this
Section, the holder(s) thereof shall promptly surrender to Orius the
certificates representing such Canceled Securities, duly endorsed for transfer
as requested by Orius, so that new certificates representing any securities
represented thereby which are not so canceled may be issued to the holder
thereof and certificates representing the Canceled Securities may be destroyed
by Orius or reissued to the Indemnitee.

                  (ii) Fair Market Value. For purposes of the foregoing, "Fair
Market Value" as to any security means the average of the closing prices of such
security's sales on all domestic securities exchanges or markets on which such
security may at the time be listed or quoted or, if there have been no sales on
any such exchange on any day, the average of the highest bid and lowest asked
prices on all such exchanges at the end of such day, or, if on any day such
security is not so listed or quoted, the average of the highest bid and lowest
asked prices on such day in the domestic over-the-counter market as reported by
the National Quotation Bureau, Incorporated, or any similar successor
organization, in each such case averaged over a period of 21 days consisting of
the day as of which "Fair Market Value" is being determined and the 20
consecutive business days prior to such day; provided that if such security is
listed on any domestic securities exchange the term "business days" as used in
this sentence means business days on which such exchange is open for trading. If
at any time such security is not listed or quoted on any domestic securities
exchange or the domestic over-the-counter market, the "Fair Market Value" shall
be the fair value thereof determined jointly by Orius and the Representatives;
provided that if Orius and the Representatives are unable to agree within 10
days of delivery of a Cancellation Notice, then by a nationally recognized
investment banking firm selected by Orius and the Representatives. The fees and
expenses of such investment banking firm shall be allocated by such firm on an
equitable basis as between the parties to such dispute and paid by such parties
accordingly.

                  7D. Defense of Third Party Claims. Any Indemnitee in
connection with a third party claim shall notify the Indemnitor of the claim in
writing promptly after receiving written notice of any action, lawsuit,
proceeding, investigation or other claim against it, describing the claim, the
amount thereof (if known and quantifiable) and the basis thereof; provided that
the failure to so notify an Indemnitor shall not relieve the Indemnitor of its
obligations hereunder except to the extent that (and only to the extent that)
such failure shall have caused the damages for which the Indemnitor is obligated
to be greater than such damages would have been had the Indemnitee given the
Indemnitor prompt notice hereunder. Any Indemnitor shall be entitled to
participate in the defense of such action, lawsuit, proceeding, investigation or
other claim giving rise to an Indemnitee's claim for indemnification at such
Indemnitor's expense, and at its option (subject to the limitations set forth
below) shall be entitled to assume the defense thereof by appointing a reputable
counsel reasonably acceptable to the Indemnitee to be the lead counsel in
connection with such defense; provided that,

                  (i) the Indemnitee shall be entitled to participate in the
defense of such claim and to employ counsel of its choice for such purpose; and

                  (ii) the Indemnitor shall not be entitled to assume control of
such defense and shall pay the fees and expenses of counsel retained by the
Indemnitee if (A) the claim for indemnification relates to or arises in
connection with any criminal proceeding, action, indictment, allegation or
investigation; (B) the Indemnitee reasonably believes an adverse determination
with respect to the action, lawsuit, investigation, proceeding or other claim
giving rise to such claim for indemnification would be materially detrimental to
or injure the Indemnitee's reputation or future business prospects; (C) the
claim seeks an injunction or equitable relief against the Indemnitee; (D) the
Indemnitee has been advised in writing by counsel that a reasonable likelihood
exists of a conflict of interest between the Indemnitor and the Indemnitee; or
(E) upon petition by the Indemnitee, the

                                      -74-
<PAGE>   83

appropriate court rules that the Indemnitor failed or is failing to vigorously
prosecute or defend such claim; and

                  (iii) if the Indemnitor shall control the defense of any such
claim, the Indemnitor shall obtain the prior written consent of the Indemnitee
before entering into any settlement of a claim or ceasing to defend such claim
if, pursuant to or as a result of such settlement or cessation, injunctive or
other equitable relief will be imposed against the Indemnitee or if such
settlement does not expressly and unconditionally release the Indemnitee from
all liabilities and obligations with respect to such claim, without prejudice.

If the Indemnitee notifies the Indemnitor of a claim in accordance with this
Section 7D, the Indemnitor shall bear all fees and expenses of counsel that are
incurred by or on behalf of the Indemnitee prior to the date on which the
Indemnitor effectively assumes control of defense (the "Control Date"). If the
Indemnitee elects to participate in the defense of such a claim in accordance
with clause (i) foregoing, the Indemnitee shall bear all fees and expenses of
such separate counsel that are incurred after the date on which the Indemnitor
has both (x) verified to the Indemnitee in writing that such Indemnitor shall be
fully responsible (with no reservation of any rights) for all liabilities and
obligations relating to such claim for indemnification and that it shall provide
full indemnification (whether or not otherwise required hereunder) to the
Indemnitee with respect to such action, lawsuit, proceeding, investigation or
other claim giving rise to such claim for indemnification hereunder, and (y)
entered into an agreement with the Indemnitee in form and substance satisfactory
to the Indemnitee under which the Indemnitor unconditionally guarantees the
payment and performance of any liability or obligation which may arise with
respect to such action, lawsuit, proceeding, investigation or facts giving rise
to such claim for indemnification hereunder. The Indemnitee shall fund all fees
and expenses of such separate counsel that are incurred in the defense of such a
claim after the Control Date and before the date on which the Indemnitor has
satisfied the conditions described in clauses (x) and (y) of the immediately
preceding sentence, but the Indemnitor will promptly reimburse the Indemnitee in
full for all of such amounts if the Indemnitor is found to be liable in respect
of any such claim.

         Representative a counterpart signature page to the Investor Rights
         Agreement;

                  (v) by the LISN Shareholder Representative, the Investor
Representative or the Orius Stockholders Representative if the transactions
contemplated hereby have not been consummated by December 22, 1999 provided that
neither the Person electing termination pursuant to this Section 9A(iv), or any
Related Person in respect of such Person, is in breach of any of its
representations, warranties, covenants or agreements contained in this Agreement
or the Schedules and Exhibits attached hereto (including without limitation the
Purchase Agreement, a Joinder Agreement, the Put Agreement or the Call
Agreement) which has caused a closing condition to the obligations of LISN set
forth in Section 2 (in the case of a breach by the Orius Stockholders
Representative, Orius or any Orius Stockholder) or of Orius set forth in Section
3 (in the case of any breach by the LISN Shareholder Representative, LISN or any
LISN Shareholder), to be unsatisfied. For purposes of the foregoing, "Related
Person"in respect of the LISN Shareholder Representative or the Investor
Representative means any of the LISN Shareholders and LISN, and in respect of
the Orius Stockholders Representative means any of Orius and the Orius
Stockholders.

Notwithstanding the immediately preceding clause, if a Representative or any of
its Related Persons has unintentionally breached this Agreement and such breach
has prevented the consummation of the transactions contemplated hereby, such
party may terminate this Agreement pursuant to this Section 9(A)(iv) if (i) such
Representative and its Related Persons who are in breach (the "Breaching
Party"), promptly upon becoming aware of such breach, delivers to LISN, Orius
and the other Representatives a written notice (a "Breach Notice") describing in
reasonable detail such breach (the "Identified Breach"), specifying the
condition described above which, because of such breach, will not be satisfied
(the "Unsatisfied Condition"), requesting that the Persons whose obligations are
subject to the Unsatisfied Condition deliver to the Breaching Party a Qualified
Waiver of the Unsatisfied Condition, and confirming that if such Persons deliver
such a waiver and consummate the transactions contemplated hereby such Persons
delivering such waiver shall be entitled to indemnification pursuant to Section
7B above in respect of such Identified Breach, and (ii) such other Persons fail
to deliver to the Breaching Party a Qualifying Waiver (as defined below) within
5 business days after receiving such Breach Notice, the Breaching Party shall
thereafter be permitted to terminate this Agreement pursuant to this Section
9A(iv). For purposes hereof, a "Qualifying Waiver" in respect of a Breach Notice
is an agreement to waive the Unsatisfied Condition described therein to the
extent that it remains unsatisfied solely due to the Identified Breach described
therein.

                  9B. Effect of Termination. In the event of termination of this
Agreement by either the LISN Shareholder Representative or Orius and the Orius
Stockholders Representative as provided above, this Agreement shall forthwith
become void and of no further force and effect, except that (i) the covenants
and agreements set forth in Section 10S. Section 7F, Section 7G and Section 10N
shall survive such termination until the applicable statute of limitations runs,
(ii) nothing in Section 9A or this Section 9B shall be deemed to release any
Person from any liability for any breach by such Person of the terms and
provisions of this Agreement prior to such


                                      -93-

termination or to impair the right of any Person to compel specific performance
by another Person of its obligations under this Agreement, except that no Person
shall be liable to any other Person for any damages arising out of such breach,
other than for such other Person's out-of-pocket costs and expenses incurred in
connection with the transactions contemplated by this Agreement (including fees
and expenses of legal counsel, accountants, investment bankers and other
representatives and consultants) unless such breach was wilful. Notwithstanding
anything herein to the contrary, in the event that the LISN Representative or
the Investor Representative elects to terminate this Agreement pursuant to
Section 9A(iv) above, Orius shall, within three business days of receiving
notice from such Person of the aggregate amount of Bridge Financing Expenses
incurred by LISN and its Affiliates, pay to LISN by wire transfer of immediately
available funds the amount of such Bridge Financing Expenses. For purposes
hereof, "Bridge Financing Expenses" means the aggregate amount of fees and
out-of-pocket expenses paid or owing by LISN pursuant to the Bridge Loan
Commitment Letter.

                  Section 10. Miscellaneous.

                  10A. Fees and Expenses. Each Party shall pay all of its own
fees and expenses (including fees and expenses of legal counsel, accountants,
investment bankers and other representatives and consultants) in connection with
this Agreement and the consummation of the transactions contemplated hereby. If
any legal action or other proceeding relating to this Agreement, the agreements
contemplated hereby, the transactions contemplated hereby or thereby or the
enforcement of any provision of this Agreement or the agreements contemplated
hereby is brought against any Party, the prevailing Party in such action or
proceeding shall be entitled to recover all reasonable expenses relating thereto
(including attorneys' fees and expenses) from the Party against which such
action or proceeding is brought in addition to any other relief to which such
prevailing Party may be entitled.

                  10B. Remedies. The Parties shall have all rights and remedies
set forth in this Agreement and all rights and remedies which the Parties have
been granted at any time under any other agreement or contract executed in
connection with the transactions contemplated hereby and, with respect to any
additional rights the Parties may have against Orius, all of the rights which
the Parties have under applicable law. Each of the Parties acknowledges and
agrees that the other Parties would be damaged irreparably in the event any of
the provisions of this Agreement are not performed in accordance with their
specific terms or otherwise are breached. Accordingly, each of the Parties
agrees that the other Parties shall be entitled to an injunction or injunctions
to prevent breaches of the provisions of this Agreement and to enforce
specifically this Agreement and the terms and provisions hereof in any action
instituted in any court of the United States or any state thereof having
jurisdiction over the Parties and the matter.

                  10C. Transfer of Restricted Securities.

                  (i) Restricted Securities are transferable only pursuant to
(a) public offerings registered under the Securities Act, (b) Rule 144 or Rule
144A of the Securities and Exchange Commission (or any similar rule or rules
then in force) if such rule is available and (c) subject to the conditions
specified in subparagraph (ii) below, any other legally available means of
transfer.

<PAGE>   103



                  (ii) In connection with the transfer of any Restricted
Securities (other than a transfer described in clause (a) or (b) of subparagraph
(i) above), the holder thereof shall deliver written notice to Orius describing
in reasonable detail the transfer or proposed transfer, together with an opinion
of Kirkland & Ellis, Akerman, Senterfitt & Eidson, White and Williams LLP or
other counsel which (to Orius's reasonable satisfaction) is knowledgeable in
securities law matters to the effect that such transfer of Restricted Securities
may be effected without registration of such Restricted Securities under the
Securities Act. In addition, if the holder of the Restricted Securities delivers
to Orius an opinion of Kirkland & Ellis, Akerman, Senterfitt & Eidson, White and
Williams LLP or such other counsel that no subsequent transfer of such
Restricted Securities shall require registration under the Securities Act, Orius
shall promptly upon such contemplated transfer deliver new certificates or
instruments, as the case may be, for such Restricted Securities which do not
bear the Securities Act legend set forth in Section 10C(v) below. If Orius is
not required to deliver new certificates or instruments, as the case may be, for
such Restricted Securities not bearing such legend, the holder thereof shall not
transfer the same until the prospective transferee has confirmed to Orius in
writing its agreement to be bound by the conditions contained in this Section
10C(ii) and Section 10C(v) below.

                  (iii) Upon the request of a holder of Restricted Securities,
Orius shall promptly supply to such holder or such holder's prospective
transferees all information regarding Orius required to be delivered in
connection with a transfer pursuant to Rule 144A of the Securities and Exchange
Commission.

                  (iv) If any Restricted Securities become eligible for sale
pursuant to Rule 144(k), Orius shall, upon the request of the holder of such
Restricted Securities, remove the legend set forth in Section 10C(v) from the
certificates or instruments, as the case may be, representing such Restricted
Securities.

                  (v) Each certificate or instrument representing Restricted
Securities shall be imprinted with a legend in substantially the following form:

                  "The Securities represented hereby have not been registered
                  under the Securities Act of 1933, as amended, or under any
                  state securities laws. Neither this security nor any portion
                  hereof or interest herein may be sold, assigned, transferred,
                  pledged or otherwise disposed of unless the same is registered
                  under said Act and applicable state securities laws or unless
                  an exemption from such registration is available and the
                  issuer hereof (the "Company") will have received evidence of
                  such exemption reasonably satisfactory to the Company."

                  10D. Consent to Amendments. This Agreement may be amended, or
any provision of this Agreement may be waived; provided that any such amendment
or waiver shall be binding upon Orius or LISN if and only if set forth in a
writing executed by Orius or LISN, respectively, and referring specifically to
the provision alleged to have



                                      -95-

<PAGE>   104


been amended or waived, any such amendment or waiver shall be binding upon the
Orius Stockholders if and only if set forth in a writing executed by the Orius
Stockholders Representative and referring specifically to the provision alleged
to have been amended or waived, and any such amendment or waiver shall be
binding upon the LISN Shareholders or the Investors if and only if set forth in
a writing executed by the LISN Shareholders Representative and the Investor
Representative and referring specifically to the provision alleged to have been
amended or waived. No course of dealing between or among the Parties shall be
deemed effective to modify, amend or discharge any part of this Agreement or any
rights or obligations of any Party under or by reason of this Agreement.

                  10E. Successors and Assigns.

                  (i) This Agreement and all covenants and agreements contained
herein and rights, interests or obligations hereunder, by or on behalf of any of
the Parties hereto, shall bind and inure to the benefit of the respective
successors and permitted assigns of the Parties hereto whether so expressed or
not, except that prior to the Closing neither this Agreement nor any of the
covenants and agreements herein or rights, interests or obligations hereunder
may be assigned or delegated by any Orius Stockholder, or assigned or delegated
by Orius, without the prior written consent of LISN and the LISN Shareholder
Representative, prior to the Closing neither this Agreement nor any of the
covenants and agreements herein or rights, interests or obligations hereunder
may be assigned or delegated by any LISN Shareholder, or assigned or delegated
by LISN, without the prior written consent of Orius and the Orius Stockholders
Representative, and after the Closing neither this Agreement nor any of the
covenants and agreements herein or rights, interests or obligations hereunder
may be assigned or delegated by any of such Persons without the prior written
consent of Orius. In connection with any such assignment, the assigning Person
shall cause the prospective assignee to execute and deliver to the Parties a
counterpart to this Agreement, and to each other agreement contemplated hereby
to which such assigning Person is or is contemplated hereby or thereby be a
party, and an acknowledgment by such Person agreeing to be bound by all terms
and provisions hereof and thereof in the same manner and to the same extent as
the assigning party was bound thereby prior to such assignment. Notwithstanding
the foregoing, any Person entitled to indemnity rights pursuant to Section 7 may
assign such Person's rights to indemnification under Section 7 of this Agreement
to any lender to Orius or any of its Subsidiaries as collateral security.

                  (ii) Orius and its Subsidiaries, and any Orius Stockholder or
LISN Shareholder may assign this Agreement and its rights and obligations
hereunder in connection with a merger or consolidation involving Orius or any of
its Subsidiaries or in connection with a sale of stock or assets of Orius or any
of its Subsidiaries or other disposition of Orius or any of its Subsidiaries.

                  10F. Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement or the application of any
such provision to any Person or circumstance shall be held to be prohibited by,
illegal or unenforceable under applicable law in any respect by a court of
competent jurisdiction, such provision shall be ineffective only to the extent
of such prohibition or illegality or unenforceability, without invalidating the
remainder of such provision or the remaining provisions of this Agreement.

                  10G. Counterparts. This Agreement may be executed
simultaneously in counterparts (including by means of telecopied signature
pages), any one of which need not contain the signatures of more than one Party,
but all such counterparts taken together shall constitute one and the same
Agreement.

                  10H. Descriptive Headings; Interpretation. The headings and
captions used in this Agreement and the table of contents to this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. Any capitalized terms used in any Schedule or
Exhibit attached hereto and not otherwise defined therein shall have the
meanings set forth in this Agreement. The use of the word "including" herein
shall mean "including without limitation." The Parties intend that each
representation, warranty and covenant contained herein shall have independent
significance. If any Party has breached any representation, warranty or covenant
contained herein in any respect, the fact that there exists another
representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the Party has not
breached shall not detract from or mitigate the fact that the Party is in breach
of the first representation, warranty or covenant. Each reference to "Orius" or
"LISN" herein shall be deemed to be a reference to such Person and its
predecessors, collectively.

                  10I. Entire Agreement. This Agreement and the agreements and
documents referred to herein contain the entire agreement and understanding
between the Parties with respect to the subject matter hereof and supersede all
prior agreements and understandings whether written or oral, relating to such
subject matter in any way.

                  10J. No Third-Party Beneficiaries. This Agreement is for the
sole benefit of the Parties and their permitted successors and assigns and
nothing herein expressed or implied shall give or be construed to give any
Person, other than the Parties and such permitted successors and assigns, any
legal or equitable rights hereunder.

                  10K. Schedules. No exceptions to any representations or
warranties disclosed on one Schedule shall constitute an exception to any other
representations or warranties made in this Agreement unless the substance of
such exception is disclosed as provided herein on each such other applicable
Schedule or a specific cross-reference to a disclosure on another Schedule is
made.

                  10L. Cooperation on Tax Matters. The Parties shall
cooperatefully, as and to the extent reasonably requested by each Party and at
the requesting Party's expense, in connection with any audit, litigation or
other proceeding with respect to Taxes. Such cooperation shall include the
retention and (upon any Party's request) the provision of records and
information which are reasonably relevant to any such audit, litigation or other
proceeding and making employees available on a mutually convenient basis to
provide additional information and explanation of any material provided
hereunder. The Parties agree (i) to retain all books and records with respect to
Tax matters pertinent to Orius and its Subsidiaries and LISN and its
Subsidiaries relating to any taxable period beginning before the Closing Date
until the expiration of the statute of limitations (and, to the extent notified
by any Party, any extensions thereof) applicable to such taxable periods, and to
abide by all record retention agreements entered into with any taxing authority,
and (ii) to give each Party reasonable written notice prior to transferring,
destroying or discarding any such books and records



                                      -97-

and, if any Party so requests, the LISN Shareholders, Orius or the Orius
Stockholders, as the case may be, shall allow such party to take possession of
such books and records.

                  10M. Schedules and Exhibits. All Schedules and Exhibits
attached hereto or referred to herein are hereby incorporated in and made a part

holders of its equity securities. All other issues and questions concerning the
construction, validity, enforcement and interpretation of this Agreement and the
Schedules and Exhibits hereto (including the Joinder Agreements, the Put
Agreements, the Call Agreements, the Note Exchange Agreement, the Purchase
Agreement and the Investment Agreement) shall be governed by, and construed in
accordance with, the laws of the State of Illinois without giving effect to any
choice of law or conflict of law rules or provisions (whether of the State of
Illinois or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Illinois. In furtherance of the
foregoing, the internal law of the State of Illinois shall control the
interpretation and construction of this Agreement (and all Schedules and
Exhibits hereto, including the Joinder Agreements, the Put Agreements (other
than the HIG Put Agreement), the Call Agreements (other than the HIG Call

CONSENTING PARTIES FURTHER WAIVES ANY OBJECTION TO THE LAYING OF VENUE FOR ANY
SUCH SUIT ACTION, OR PROCEEDING IN SUCH COURTS AND

AGREES NOT TO ASSERT ANY DEFENSE OF LACK OF PERSONAL JURISDICTION, IMPROPER
VENUE OR FORUM NON CONVENIENS IN CONNECTION WITH ANY SUCH SUIT, ACTION OR
PROCEEDING.

                  (iii) EACH CONSENTING PARTY AGREES TO ACCEPT AND ACKNOWLEDGE
SERVICE OF ANY AND ALL PROCESS THAT MAY BE SERVED, AND IRREVOCABLY AGREES TO BE

SERVICE, THE CONSENTING PARTY HEREBY AGREES THAT SERVICE UPON SUCH AGENT,
REPRESENTATIVE OR CONSENTING PARTY BY MAIL SHALL CONSTITUTE SUFFICIENT NOTICE.
NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW.

                  (iv) EACH CONSENTING PARTY ON BEHALF OF ITSELF, ITS SUCCESSORS

                               B. PREFERRED SHARES

                  There shall be designated four series of Preferred Stock of
the Corporation: Series A Preferred, Series B Preferred, Series C Participating
Preferred and Series D Preferred. The number of shares of Preferred Stock shall
be as set forth in this Article Four. The rights, preferences and limitations of
the Preferred Stock are as set forth below.

1.       Series A Preferred.

                  Section 1. Dividends.

                  a. Dividends. The holders of the then outstanding shares of
Series A Preferred Stock shall be entitled to receive, out of funds legally
available therefor, cumulative annual dividends when and as may be declared from
time to rime by the Board at an annual rate per share equal to eight percent
(8%) of the original purchase price paid per share of the Series A Preferred
Stock. Such amount shall be compounded annually such that if the dividend is not
paid for such year the unpaid amount shall be added to the original purchase
price paid per share of the Series A Preferred Stock for purposes of calculating
succeeding years' dividends. Such dividends shall be deemed to accrue on the
Series A Preferred Stock and be cumulative, whether or not earned or declared
and whether or not there are profits, surplus or other funds of the Corporation
legally available for the payment of dividends. If such cumulative dividends in
respect of any prior or current annual dividend period shall not have been
declared and paid, or if there shall not have been a sum sufficient for the
payment therefor set apart, the deficiency shall first be fully paid before any
dividend or other distribution shall be paid or declared and set apart with
respect to any class of the

                                       -2-

<PAGE>   3


Corporation's capital stock, now or hereafter outstanding. As of the date
hereof, the Series A Preferred Stock shall be deemed to have accrued dividends
in the amount of $630,985. Anything contained herein to the contrary
notwithstanding, any accrued dividends shall be immediately due and payable in
cash, upon the earliest occurrence of any of the following (each a "Series A
Dividend Date"):


                  (i)   A Series A Qualified Public Offering (as hereafter
defined);

                  (ii)  A sale of the Corporation or a sale of all or
substantially all of the Corporation's assets; or

                  (iii) April 15, 2005.

For purposes of this Section 1, unless the context requires otherwise,
"distribution" shall mean the transfer of cash or property without
consideration, whether by way of dividend or otherwise, or the purchase or
redemption of shares of capital stock of the Corporation for cash or property,
including any such transfer, purchase or redemption by a subsidiary of the
Corporation. Notwithstanding the foregoing, the Corporation shall not declare or
pay a dividend on the Series A Preferred Stock prior to the Series A Dividend
Date.

                  b. Dividends in Kind. In the event the Corporation shall make
or issue, or shall fix a record date for the determination of holders of the
Corporation's Common Stock entitled to receive, a dividend or other distribution
with respect to the Common Stock payable in (i) securities of the Corporation
other than shares of Common Stock or (ii) assets, then and in each such event
the holders of Series A Preferred Stock shall receive, at the same time such
distribution is made with respect to Common Stock, the number of securities or
such other assets of the Corporation which they would have received had their
Series A Preferred Stock been converted into Common Stock immediately prior to
the record date for determining holders of Common Stock entitled to receive such
distribution.

                  Section 2. Liquidation, Dissolution or Winding Up.

                  a. Treatment at Liquidation, Dissolution or Winding Up. In the
event of any liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the holders of each share of Series A Preferred Stock
shall be entitled to be paid out of the assets of the Corporation available for
distribution to holders of the Corporation's capital stock of all classes,
whether such assets are capital, surplus, or capital earnings, such amount per
share of Series A Preferred Stock as would have been payable had each such share
been converted into Common Stock immediately prior to such event of liquidation,
dissolution or winding up pursuant to the provisions of Section 4 (the "Series A
Liquidation Amount") and the holders of the Series A Preferred Stock shall be
treated as if they had converted the Series A Preferred Stock into Common Stock.

                  b. Distribution in Cash. The Series A Liquidation Amount shall
in all events be paid in cash. Whenever a distribution provided for in this
Section 2 is payable in property other than

                                       -3-


<PAGE>   4


cash, the value of such distribution shall be the fair market value of such
property as determined in good faith by the Board.

                  Section 3. Voting Power. Except as otherwise expressly
provided in Section 6 hereof, or as required by law, the holder of each share of
Series A Preferred Stock shall be entitled to vote on all matters and shall be
entitled to that number of votes equal to the largest number of whole shares of
Common Stock into which a share of such holder's shares of Series A Preferred
Stock could be converted, pursuant to the provisions of Section 4 hereof, at the
record date for the determination of shareholders entitled to vote on such
matter or, if no such record date is established, at the date such vote is taken
or any written consent of shareholders is solicited. Except as otherwise
expressly provided herein or as required by law, the holders of shares of Series
A Preferred, Series B Preferred, Series C Participating Preferred and Common
Stock shall vote together as a single class on all matters.

                  Section 4. Conversion Rights for the Series A Preferred Stock.
The holders of the Series A Preferred Stock shall have following rights with
respect to the conversion of the Series A Preferred Stock into shares of Common
Stock:

                  a. General. Subject to and in compliance with the provisions
of this Section 4, all but not less than all of the shares of the Series A
Preferred Stock may, at the option of the holder, be converted at any time into
fully paid and non-assessable shares of Common Stock. As of the date hereof,
the number of shares of Common Stock to which a holder of each share of Series A
Preferred Stock shall be entitled upon conversion is 30.08257, which number is
derived by dividing $450.00 by $14.958828 (the "Series A Applicable Conversion
Value"), which Series A Applicable Conversion Value shall be adjusted from time
to time in accordance with this Section 4.

                  b. Adjustments to Series A Applicable Conversion Values.

                     (i) (A) Upon Sale of Common Stock. If the Corporation
shall, while there are any shares of Series A Preferred Stock outstanding, issue
or sell (or in accordance with Section 4(b)(i)(B) is deemed to have issued or
sold) shares of its Common Stock without consideration or at a price per share
less than the Series A Applicable Conversion Value, then in each such case such
Series A Applicable Conversion Value for the Series A Preferred Stock, upon each
such issuance or sale, except as herein after provided, shall be lowered so as
to be equal to an amount determined by multiplying the Series A Applicable
Conversion Value at such time by a fraction:

                             (1) the numerator of which shall be (a) the number
of shares of Common Stock outstanding immediately prior to the issuance of such
additional shares of Common Stock, plus (b) the number of shares of Common Stock
which the net aggregate consideration, if any, received by the Corporation for
the total number of such additional shares of Common Stock so issued would
purchase at the Series A Applicable Conversion Value in effect immediately prior
to such issuance, and

                                       -4-

<PAGE>   5


                         (2) the denominator of which shall be (a) the number of
shares of Common Stock outstanding immediately prior to the issuance of such
additional shares of Common Stock plus (b) the number of such additional shares
of Common Stock so issued.

                    (B) Upon Issuance of Warrants, Options and Rights to
Common Stock.

                         (1) For the purposes of this Section 4(b)(i), the
issuance of any warrants, options, subscriptions, or purchase rights with
respect to shares of Common Stock and the issuance of any securities convertible
into or exchangeable for shares of Common Stock (or the issuance of any
warrants, options or any rights with respect to such convertible or exchangeable
securities) shall be deemed an issuance of such Common Stock at such time if the
Series A Net Consideration Per Share (as hereinafter determined) which may be
received by the Corporation for such Common Stock shall be less than the Series
A Applicable Conversion Value at such time. Any obligation, agreement, or
undertaking to issue warrants, options, subscriptions, or purchase rights at any
time in the future shall be deemed to be an issuance at the time such
obligation, agreement or undertaking is made or arises. No adjustment of the
Series A Applicable Conversion Value shall be made under this Section 4(b)(i)
upon the issuance of any shares of Common Stock which are issued pursuant to the
exercise of any warrants, options, subscriptions, or purchase rights or pursuant
to the exercise of any conversion or exchange rights in any convertible
securities if any adjustment shall previously have been made or deemed not
required hereunder, upon the issuance of any such warrants, options, or
subscription or purchase rights or upon the issuance of any convertible
securities (or upon the issuance of any warrants, options or any rights
therefor) as provided above.

Should the Series A Net Consideration Per Share of any such warrants, options,
subscriptions or purchase rights or convertible securities be decreased from
time to time, then, upon the effectiveness of each such change, the Series A
Applicable Conversion Value shall be adjusted to such Series A Applicable
Conversion Value as would have obtained (1) had the adjustments made upon the
issuance of such warrants, options, rights, or convertible securities been made
upon the basis of the decreased Series A Net Consideration Per Share of such
securities, and (2) had adjustments made to the Series A Applicable Conversion
Value since the date of issuance of such securities been made to the Series A
Applicable Conversion Value as adjusted pursuant to (1) above.

                         (2) For Purposes of this paragraph, the "Series A Net
Consideration Per Share" which may be received by the Corporation shall be
determined as follows:

                              I. The "Series A Net Consideration Per Share"
          shall mean the amount equal to the total amount of consideration, if
          any, received by the Corporation for the issuance of such warrants,
          options, subscriptions, or other purchase rights or convertible or
          exchangeable securities, plus the minimum amount of consideration, if
          any, payable to the Corporation upon exercise or conversion thereof,
          divided by the aggregate number of shares of Common Stock that would
          be issued if all such warrants, options, subscriptions, or other
          purchase rights or convertible or exchangeable securities were
          exercised, exchanged, or converted.

                                       -5-

<PAGE>   6




                         II. The "Series A Net Consideration Per Share" which
may be received by the Corporation shall be determined in each instance as of
the date of issuance of warrants, options, subscriptions, or other purchase
rights or convertible or exchangeable securities without giving effect to any
possible future upward price adjustments or rate adjustments which may be
applicable with respect to such warrants, options, subscriptions, or other
purchase rights or convertible or exchangeable securities.

                     (C) Stock Dividends. In the event the Corporation shall
make or issue a dividend or other distribution payable in Common Stock or
securities of the Corporation convertible into or otherwise exchangeable for the
Common Stock of the Corporation, then such Common Stock or other securities
issued in payment of such dividend shall be deemed to have been issued without
consideration (except for dividends payable in shares of Common Stock payable
pro rata to holders of Series A Preferred Stock and to holders of any other
class of stock).

                     (D) Consideration Other than Cash. For purposes of this
Section 4(b) if a part or all of the consideration received by the Corporation
in connection with the issuance of shares of the Common Stock or the issuance of
any of the securities described in this Section 4(b) consists of property other
than cash, such consideration shall be deemed to have a fair market value as is
reasonably determined in good faith by the board.

                     (E) Exceptions. This Section 4(b)(i) shall not apply under
any of the circumstances which would constitute an Extraordinary Common Stock
Event (as hereinafter defined in Section 4(b)(ii)). Further, the provisions of
this Section 4(b) shall not apply to (i) shares issued upon conversion of the
Series A Preferred Stock, (ii) the issuance of any Common Stock pursuant to the
exercise of the options (and the shares issuable upon exercise thereof) to
purchase up to an aggregate of 140,000 shares of Common Stock (excluding options
outstanding on the date hereof) issued to employees of the Corporation, or
(iii) the issuance of warrants to the Corporation's lenders in connection with
that certain Warrant Agreement among the Corporation, Merrill Lynch & Co.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, PNC Bank, National
Association, and certain other holders party thereto, dated as of February 26,
1999. The number of shares in this Section (E) shall be proportionately adjusted
to reflect any stock dividend, stock split or other form of recapitalization
occurring after the date hereof.

                  (ii) Upon Extraordinary Common Stock Event. Upon the happening
of an Extraordinary Common Stock Event (as hereinafter defined), the
Series A Applicable Conversion Value for the Series A Preferred Stock shall,
simultaneously with the happening of such Extraordinary Common Stock Event, be
adjusted by multiplying the then effective Series A Applicable Conversion Value
with respect to the Series A Preferred Stock by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such Extraordinary Common Stock Event and the denominator of which
shall be the number of shares of Common Stock outstanding immediately after
such Extraordinary Common Stock Event, and the product so obtained shall
thereafter be the Series A Applicable Conversion Value. The

                                       -6-

<PAGE>   7


Series A Applicable Conversion Value for the Series A Preferred Stock shall be
readjusted in the same manner upon the happening of any successive Extraordinary
Common Stock Event or Events.

                  "Extraordinary Common Stock Event" shall mean (i) the issue of
                  additional shares of Common Stock as a dividend or other
                  distribution on outstanding Common Stock or on any class or
                  series of preferred stock, unless made pro rata to holders of
                  Preferred Stock, (ii) a subdivision of outstanding shares of
                  Common Stock into a greater number of shares of Common Stock,
                  or (iii) a combination of outstanding shares of the Common
                  Stock into a smaller number of shares of Common Stock.

                  c. Dividends. In the event the Corporation shall make or
issue, or shall fix a record date for the determination of holders of Common
Stock entitled to receive, a dividend or other distribution with respect to the
Common Stock payable in (i) securities of the Corporation other than shares of
Common Stock or (ii) assets, then and in each such event the holders of Series A
Preferred Stock shall receive, at the same time such distribution is made with
respect to Common Stock, the number of securities or such other assets of the
Corporation which they would have received had their Series A Preferred Stock
been converted into Common Stock immediately prior to the date of such
distribution.

                  d. Capital Reorganization or Reclassification. If the Common
Stock issuable upon the conversion of the Series A Preferred Stock shall be
changed into the same or different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision or combination of shares or stock dividend provided for
elsewhere in this Section 4 or by a Reorganization), then and in each such
event, the holder of each share of Series A Preferred Stock shall have the right
thereafter to convert such share into the kind and amount of shares of stock and
other securities and property receivable upon such capital reorganization,
reclassification or other change by holders of the number of shares of Common
Stock into which such shares of Series A Preferred Stock might have been
converted immediately prior to such capital reorganization, reclassification or
other change.

                  e. Capital Reorganization, Merger or Sale of Assets. If at any
time or from time to time there shall be a capital reorganization of the Common
Stock (other than a subdivision, combination, reclassification or exchange of
shares provided for elsewhere in this Section 4) or a merger or consolidation of
the Corporation with or into another corporation, or the sale of all or
substantially all of the Corporation's properties and assets to any other
person, or any transaction or series of related transactions in which more than
fifty percent (50%) of the outstanding voting securities of the Corporation (on
an as-converted basis) is sold or assigned (any of which events is herein
referred to as a "Reorganization"), then as a part of such Reorganization,
provision shall be made so that the holders of the Series A Preferred Stock
shall thereafter be entitled to receive upon conversion of the Series A
Preferred Stock, the number of shares of stock or other securities or property
of the Corporation, or of the successor corporation resulting from such
Reorganization, to which such holder would have been entitled if such holder had
converted its shares of Series A

                                       -7-

<PAGE>   8


Preferred Stock immediately prior to such Reorganization. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 4 with respect to the rights of the holders of the Series A
Preferred Stock after the Reorganization, to the end that the provisions of this
Section 4 (including adjustment of the Series A Applicable Conversion Value then
in effect and the number of shares issuable upon conversion of the Series A
Preferred Stock) shall be applicable after that event in as nearly equivalent a
manner as may be practicable.

                  f. Certificate as to Adjustments; Notice by Corporation. In
each case of an adjustment or readjustment of the Applicable Conversion Rate,
the Corporation at its expense will furnish each holder of Series A Preferred
Stock with a certificate, executed by the president and chief financial officer
(or in the absence of a person designated as the chief financial officer, by the
treasurer) showing such adjustment or readjustment, and stating in detail the
facts upon which such adjustment or readjustment is based.

                  g. Exercise of Conversion Privilege. To exercise its
conversion privilege, a holder of Series A Preferred Stock shall surrender the
certificate or certificates representing the shares being converted to the
Corporation at its principal office, and shall give written notice to the
Corporation at that office that such holder elects to convert such shares. Such
notice shall also state the name or names (with address or addresses) in which
the certificate or certificates for shares of Common Stock issuable upon such
conversion shall be issued. The certificate or certificates for shares of Series
A Preferred Stock surrendered for conversion shall be accompanied by proper
assignment thereof to the Corporation or in blank. The date when such written
notice is received by the Corporation, together with the certificate or
certificates representing the shares of Series A Preferred Stock being
converted, shall be the "Series A Conversion Date." As promptly as practicable
after the Series A Conversion Date, the Corporation shall issue and shall
deliver to the holder of the shares of Series A Preferred Stock being converted,
or on its written order, such certificate or certificates as it may request for
the number of whole shares of Common Stock issuable upon the conversion of such
shares of Series A Preferred Stock in accordance with the provisions of this
Section 4, and cash, as provided in Section 4(h), in respect of any fraction of
a share of Common Stock issuable upon such conversion. Such conversion shall be
deemed to have been effected immediately prior to the close of business on the
Series A Conversion Date, and at such time the rights of the holder as holder of
the converted shares of Series A Preferred Stock shall cease and the person or
persons in whose name or names any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become the holder or holders of record of the shares of Common Stock represented
thereby. The Corporation shall pay any taxes payable with respect to the
issuance of Common Stock upon conversion of the Series A Preferred Stock, other
than any taxes payable with respect to income by the holders thereof.

                  h. Cash in Lieu of Fractional Shares. The Corporation may, if
it so elects, issue fractional shares of Common Stock or scrip representing
fractional shares upon the conversion of shares of Series A Preferred Stock. If
the Corporation does not elect to issue fractional shares, the Corporation shall
pay to the holder of the shares of Series A Preferred Stock which were converted
a cash adjustment in respect of such fractional shares in an amount equal to the
same fraction of the market price per share of the Common Stock (as determined
in a reasonable manner prescribed by

                                       -8-

<PAGE>   9


the Board) at the close of business on the Series A Conversion Date. The
determination as to whether or not any fractional shares are issuable shall be
based upon the total number of shares of Series A Preferred Stock being
converted at any one time by any holder thereof, not upon each share of Series A
Preferred Stock being converted.

                  i. Reservation of Common Stock. The Corporation shall at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock, solely for the purpose of effecting the conversion of the shares
of the Series A Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A Preferred Stock, and if at any time the
number of authorized but unissued shares of Common Stock shall not be sufficient
to effect the conversion of all then outstanding shares of the Series A
Preferred Stock, the Corporation shall take such corporate action as may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purpose.

         Section 5. No Reissuance of Series A Preferred Stock. No share or
shares of Series A Preferred Stock acquired by the Corporation by reason of
redemption, purchase, conversion or otherwise shall be reissued, and all such
shares shall be canceled, retired and eliminated from the shares which the
Corporation shall be authorized to issue. The Corporation may from time to time
take such appropriate corporate action as may be necessary to reduce the
authorized number of shares accordingly.

         Section 6. Redemption.

                    a. Optional Redemption Upon Series A Qualified Public
Offering. Effective upon the closing of a Series A Qualified Public Offering,
the Corporation may require the holders of the Series A Preferred Stock to
convert their Series A Preferred Stock into Common Stock by sending notice
thereof, together with a calculation of the Series A Applicable Conversion
Value, at least ten business days prior to the closing of the Series A
Qualified Public Offering, to all holders of Series A Preferred Stock. The
mandatory conversion shall be effective as of the closing date of the Series A
Qualified Public Offering and on and after such date the certificates
representing the Series A Preferred Stock shall only represent the right to
receive the Conversion Shares. For purposes hereof, the term "Series A
Qualified Public Offering" shall mean an underwritten public offering pursuant
to an effective registration statement under the Securities Act, covering the
offer and sale of Common Stock for the account of the Corporation in which the
aggregate net proceeds to the Corporation equal at least $25,000,000 and in
which the price per share of Common Stock is at least two and one half (2.5)
times the then Series A Applicable Conversion Value of the Series A Preferred
Stock. Nothing contained in Section 6(a) shall (i) in any way restrict or
prohibit the holders of the Series A Preferred Stock from exercising their
conversion rights pursuant to Section 4 hereof prior to the effective date of
the redemption to be effected hereunder; provided, however, that any such
conversion under Section 6(a) may be subject to the closing of the Series A
Qualified Public Offering.

                    b. Optional Redemption by a Holder Following Default.

                                       -9-

<PAGE>   10
                    (i) In the event there is an Event of Default under the
Subscription Agreement and the applicable cure period, if any, has expired (a
"Default"), then the holders of at least fifty-one percent (51%) of the then
outstanding shares of Series A Preferred Stock may request the Corporation to
redeem any or all of the shares of Series A Preferred Stock then held by such
holders at the price equal to the greater of (i) the original purchase price of
the Series A Preferred Stock (as adjusted to reflect any stock split, stock
dividend or other form of recapitalization), together with all accrued and
unpaid dividends (whether or not declared) thereon to be calculated and paid
through and including the date of redemption or (ii) fair market value thereof,
as of the date of such proposed redemption, as determined, at the Corporation's
sole expense, by a nationally recognized investment banking firm (mutually
acceptable to both the Corporation and the holders), taking into account, in
valuing such Shares, all relevant facts and circumstances; provided, however,
that there shall be no discount to reflect the fact that the Shares represent a
minority interest in the Corporation (the Holder Redemption Price"). Such
request (the "Default Redemption Request") shall be submitted to the Corporation
in writing within thirty (30) days after the Corporation notifies all of the
holders of the Series A Preferred Stock in writing of the Default. No cure of
such Default during such thirty (30) day period shall vitiate such Default
Redemption Request and the failure to make such a Default Redemption Request
within such thirty (30) day period shall not result in the waiver of such
remedy.

                    (ii) Upon receipt of a Default Redemption Request, the
Corporation shall promptly give notice thereof (the "Default Redemption Notice")
to each holder of Series A Preferred Stock. Such Default Redemption Notice shall
specify the number of shares of Series A Preferred Stock covered by the Default
Redemption Request and the Holder Redemption Price to be paid with respect
thereto. Any holder of Series A Preferred Stock who wishes to join in the
Default Redemption Request may do so by so advising the Corporation in writing
within 15 days after receipt of the Default Redemption Notice specified in the
preceding sentence. No holder of Series A Preferred Stock shall be required to
participate in such redemption. The Corporation shall redeem all shares of
Series A Preferred Stock covered by the Default Redemption Request (including
those held by holders who have requested a redemption following receipt of the
Default Redemption Notice) at a closing to be held not more than thirty (30)
days after the date of the Default Redemption Request. At the closing, the
Corporation shall pay for the shares of Series A Preferred Stock so redeemed in
an amount equal to the Holder Redemption Price, payable in cash.

                    c. Optional Redemption by Holders. At the election of the
holders of at least fifty-one percent (51%) of the then outstanding shares of
Series A Preferred Stock, the Corporation shall, to the extent it may do so
under applicable law, redeem pro rata from all holders of Series A Preferred
Stock on April 15, 2005 the Shares of Series A Preferred Stock outstanding on
the date of such redemption (the "Final Redemption Date"). The Corporation shall
give the holders of the Series A Preferred Stock at least ninety (90) days'
notice of the Final Redemption Date (the "Final Redemption Notice"). In the
event that the Corporation does not provide the Final Redemption Notice, the
option of the holders of the Series A Preferred Stock to require the Corporation
to redeem the remaining shares of Series A Preferred Stock on the Final
Redemption Date shall be extended beyond the Final Redemption Date to a date
which is ninety (90) days from the date that the Corporation elects to mail the
Final Redemption Notice. In the event shares of

                                      -10-

<PAGE>   11


Series A Preferred Stock scheduled for redemption are not redeemed because of a
prohibition under applicable law, such shares shall be redeemed as soon as such
prohibition no longer exists. The redemption price for each share of Series A
Preferred Stock redeemed pursuant to this Section 6(c) shall be equal to the
Holder Redemption Price.

         In the event that the holders of the Series A Preferred Stock do not
elect to have the Series A Preferred Stock redeemed pursuant to this Section
6(c), the shares of Series A Preferred Stock shall remain outstanding and
subject to the rights and preferences contained herein.

                  d. Redemption Notice. If an election is made pursuant to
Section 6(c) hereof, written notice of such election shall be mailed, postage
prepaid, to the Corporation, not later than sixty (60) days before the date
fixed for each redemption pursuant to Section 6(c) or, in the event the
Corporation does not provide the Final Redemption Notice pursuant to Section
6(c) hereof, not later than sixty (60) days before the date that the Final
Redemption Date has been extended as provided in Section 6(c) (each of the dates
fixed for redemption and the extended redemption date is hereinafter referred to
as a "Redemption Date"). If such election is made and appropriate notice is
given, then, at least forty-five (45) days before the Redemption Date, written
notice (hereinafter referred to as the "Redemption Notice") shall be mailed by
the Corporation, postage prepaid, to each holder of record of Series A Preferred
Stock at its address shown on the records of the Corporation; provided, however,
that the Corporation's failure to give such Redemption Notice shall in no way
affect its obligation to redeem the shares of Series A Preferred Stock or the
obligation of the holders to redeem their shares of Series A Preferred Stock as
provided in Section 6(c) hereof. The Redemption Notice shall contain (i) the
number of shares of Series A Preferred Stock held by the holder and the total
number of shares of Series A Preferred Stock held by all holders subject to
redemption as of such Redemption Date; and (ii) the Redemption Date and the
applicable Holder Redemption Price. Any holder of Series A Preferred Stock who
wishes to do so may, by giving notice to the Corporation prior to the Redemption
Date, convert into Common Stock any or all of the shares of Series A Preferred
Stock held by him and scheduled for redemption on such Redemption Date.

                  e. Surrender of Certificates. Each holder of shares of Series
A Preferred Stock to be redeemed under this Section 6 shall surrender the
certificate or certificates representing such shares to the Corporation at the
place designated in the Redemption Notice, and thereupon the Corporation
Redemption Price or Holder Redemption Price, as the case may be, for such shares
as set forth in this Section 6 shall be paid to the order of the person whose
name appears on such certificate or certificates. Irrespective of whether the
certificates therefor shall have been surrendered, all shares of Series A
Preferred Stock which are the subject of a Redemption Notice shall be deemed to
have been redeemed and shall be canceled effective as of the Redemption Date,
unless the Corporation shall default in the payment of the applicable Redemption
Price.

                  f. Sale of the Corporation. In lieu of the redemption
obligations of the Corporation as set forth herein, the Corporation may instead
retain a nationally recognized investment banking firm (or other mutually
acceptable party) to sell the Corporation, provided that

                                      -11-

<PAGE>   12


the Corporation acts expeditiously and in good faith and the sale of the
Corporation is consummated no later than 180 days after the required date of
redemption.

         Section 7. Restrictions and Limitations.

                  a. Corporate Securities Action. Except as expressly provided
herein or as otherwise required by law, so long as any shares of Series A
Preferred Stock remain outstanding, the Corporation shall not, and shall not
permit any subsidiary (which shall mean any corporation, association or other
business entity which the Corporation and/or any of its other subsidiaries
directly or indirectly owns at the time more than fifty percent (50%) of the
outstanding voting shares of such corporation or trust, other than directors'
qualifying shares) to, without the approval by vote or written consent by the
holders of at least a majority of the then outstanding shares of the
Corporation's Series B Preferred Stock and the Series A Preferred Stock, voting
as a separate class:

                  (i) redeem, purchase or otherwise acquire for value (or pay
into or set aside for a sinking fund for such purpose), or declare and pay or
set aside funds for the payment of any dividend with respect to, any share or
shares of capital stock, except as required or permitted hereunder or under the
terms of Section 4.2 of the Subscription Agreement;

                  (ii) authorize or issue, or obligate itself to authorize or
issue, additional shares of Series A Preferred Stock;

                  (iii) authorize or issue, or obligate itself to authorize or
issue, any equity security senior to or on parity with the Series A Preferred
Stock as to liquidation preferences, dividend rights, or voting rights;

                  (iv) merge or consolidate with any other corporation or sell,
assign, lease or otherwise dispose of or voluntarily part with the control of
(whether in one transaction or in a series of transactions) all, or
substantially all, of its assets (whether now owned or hereinafter acquired), or
consent to any liquidation, dissolution or winding up of the Corporation, or
permit any subsidiary to do any of the foregoing, except for (A) any
wholly-owned subsidiary may merge into or consolidate with or transfer assets
to any other wholly-owned subsidiary, and (B) any wholly-owned subsidiary may
merge into or transfer assets to the Corporation; or

                  (v) amend, restate, modify or alter the by-laws of the
Corporation in any way which adversely affects the rights of the holders of the
Series A Preferred Stock.

                  b. Amendments to Charter. The Corporation shall not amend its
Articles of Incorporation without the approval, by vote or written consent, by
the holders of at least a majority of the then outstanding shares of Series A
Preferred Stock, if such amendment would amend any of the rights, preferences,
privileges of or limitations provided for herein for the benefit of any shares
of Series A Preferred Stock. Without limiting the generality of the preceding
sentence, the Corporation shall not amend its Articles of Incorporation without
the approval by the holders of

                                      -12-

<PAGE>   13


at least a majority of the then outstanding shares of Series A Preferred Stock
if such amendment would:

                  (i) change the relative seniority rights of the holders of
Series A Preferred Stock as to the payment of dividends in relation to the
holders of any other capital stock of the Corporation, or create any other class
or series of capital stock entitled to seniority as to the payment of dividends
in relation to the holders of Series A Preferred Stock;

                  (ii) reduce the amount payable to the holders of Series A
Preferred Stock upon the voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, or change the relative seniority of the
liquidation preferences of the holders of Series A Preferred Stock to the rights
upon liquidation of the holders of other capital stock of the Corporation, or
change the dividend rights of the holders of Series A Preferred Stock;

                  (iii) cancel or modify the conversion rights of the holders of
Series A Preferred Stock provided for in Section 4 herein;

                  (iv) cancel or modify the redemption rights of the holders of
the Series A Preferred Stock provided for in Section 6 herein; or

                  (v) cancel or modify the rights of the holders of the Series A
Preferred Stock provided for in this Section 7.

         Section 8. No Dilution or Impairment. The Corporation shall not, by
amendment of its Articles of Incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of the Series A Preferred Stock set forth
herein, but shall at all times in good faith assist in the carrying out of all
such terms in the taking of all such actions as may be necessary or appropriate
in order to protect the rights of the holders of the Series A Preferred Stock
against dilution or other impairment. Without limiting the generality of the
foregoing, the Corporation (a) shall not increase the par value of any shares
of stock receivable on the conversion of the Series A Preferred Stock above the
amount payable therefor on such conversion, (b) shall take all such action as
may be necessary or appropriate in order that the Corporation may validly and
legally issue fully paid and nonassessable shares of stock on the conversion
of all Series A Preferred Stock from time to time outstanding, and (c) shall not
consolidate with or merge into any other person or permit any such person to
consolidate with or merge into the Corporation (if the Corporation is not the
surviving person), unless such other person shall expressly assume in writing
and will be bound by all of the terms of the Series A Preferred Stock set forth
herein.

         Section 9. Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution, or any right to subscribe for, purchase or

                                      -13-

<PAGE>   14

otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, or

                  a. any capital reorganization of the Corporation, any
reclassification or recapitalization of the capital stock of the Corporation,
any merger of the Corporation, or any transfer of all or substantially all of
the assets of the Corporation to any other corporation, or any other entity or
person, or

                  b. any voluntary or involuntary dissolution, liquidation or
winding up of the Corporation,

then and in each such event the Corporation shall mail or cause to be mailed to
each holder of Series A Preferred Stock a notice specifying (i) the date on
which any such record is to be taken for the purpose of such dividend,
distribution or right and a description of such dividend, distribution or right,
(ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, merger, dissolution, liquidation or winding up is
expected to become effective, and (iii) the time, if any, that is to be fixed,
as to when the holders of record of Common Stock (or other securities) shall be
entitled to exchange their shares of Common Stock (or other securities) for
securities or other property deliverable upon such reorganization,
reclassification, recapitalization, transfer, merger, dissolution, liquidation
or winding up. Such notice shall be mailed at least ten (10) business days prior
to the date specified in such notice on which such action is to be taken.

II. Series B Preferred.

         Section 1. Dividends.


         a. Dividends. The holders of the then outstanding shares of Series B
Preferred Stock shall be entitled to receive, out of funds legally available
therefor, cumulative annual dividends when and as may be declared from time to
time by the Board of Directors of the Corporation at an annual rate per share
equal to eight percent (8%) of the original purchase price paid per share of the
Series B Preferred Stock. Such amount shall be compounded annually such that if
the dividend is not paid for such year the unpaid amount shall be added to the
original purchase price paid per share of the Series B Preferred Stock for
purposes of calculating succeeding years' dividends. Such dividends shall be
deemed to accrue on the Series B Preferred Stock and be cumulative, whether or
not earned or declared and whether or not there are profits, surplus or other
funds of the Corporation legally available for the payment of dividends. If such
cumulative dividends in respect of any prior or current annual dividend period
shall not have been declared and paid, or if there shall not have been a sum
sufficient for the payment therefor set apart, the deficiency shall first be
fully paid before any dividend or other distribution shall be paid or declared
and set apart with respect to any class of the Corporation's capital stock, now
or hereafter outstanding. As of the date hereof, the Series B Preferred Stock
shall be deemed to have accrued dividends in the amount of $479,389. Anything
contained herein to the contrary notwithstanding, any accrued dividends shall be
immediately due and payable in cash, upon the earliest occurrence of any of the
following (each a "Series B Dividend Date"):

                                      -14-

<PAGE>   15




                  (i) A Series B Qualified Public Offering (as hereafter
defined);

                  (ii) A sale of the Corporation or a sale of all or
substantially all of the Corporation's assets; or

                  (iii) April 15,2005.

For purposes of this Section 1, unless the context requires otherwise,
"distribution" shall mean the transfer of cash or property without
consideration, whether by way of dividend or otherwise, or the purchase or
redemption of shares of capital stock of the Corporation for cash or property,
including any such transfer, purchase or redemption by a subsidiary of the
Corporation. Notwithstanding the foregoing, the Corporation shall not declare
or pay a dividend on the Series B Preferred Stock prior to the Series B Dividend
Date.

         b. Dividends in Kind. In the event the Corporation shall make or issue,
or shall fix a record date for the determination of holders of the Corporation's
Common Stock entitled to receive, a dividend or other distribution with respect
to the Common Stock payable in (i) securities of the Corporation other than
shares of Common Stock or (ii) assets, then and in each such event the holders
of Series B Preferred Stock shall receive, at the same time such distribution is
made with respect to Common Stock, the number of securities or such other assets
of the Corporation which they would have received had their Series B Preferred
Stock been converted into Common Stock immediately prior to the record date for
determining holders of Common Stock entitled to receive such distribution.

         Section 2. Liquidation, Dissolution or Winding Up.

         a. Treatment at Liquidation, Dissolution or Winding Up. In the event of
any liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the holders of each share of Series B Preferred Stock
shall be entitled to be paid out of the assets of the Corporation available for
distribution to holders of the Corporation's capital stock of all classes,
whether such assets are capital, surplus, or capital earnings, such amount per
share of Series B Preferred Stock as would have been payable had each such share
been converted into Common Stock immediately prior to such event of liquidation,
dissolution or winding up pursuant to the provisions of Section 4 (the "Series B
Liquidation Amount") and the holders of the Series B Preferred Stock shall be
treated as if they had converted the Series B Preferred Stock into Common Stock.

         b. Distribution in Cash. The Series B Liquidation Amount shall in all
events be paid in cash. Whenever a distribution provided for in this Section 2
is payable in property other than cash, the value of such distribution shall be
the fair market value of such property as determined in good faith by the Board.

         Section 3. Voting Power. Except as otherwise expressly provided in
Section 6 hereof, or as required by law, the holder of each share of Series B
Preferred Stock shall be entitled to vote on all matters and shall be entitled
to that number of votes equal to the largest number of

                                      -15-

<PAGE>   16


whole shares of Common Stock into which a share of such holder's shares of
Series B Preferred Stock could be converted, pursuant to the provisions of
Section 4 hereof and assuming a Series B Applicable Conversion Value of $35.00,
at the record date for the determination of shareholders entitled to vote on
such matter or, if no such record date is established, at the date such vote is
taken or any written consent of shareholders is solicited. Except as otherwise
expressly provided herein or as required by law, the holders of shares of
Series B Preferred, Series A Preferred, Series C Participating Preferred and
Common Stock shall vote together as a single class on all matters.

         Section 4. Conversion Rights for the Series B Preferred Stock. The
holders of the Series B Preferred Stock shall have following rights with respect
to the conversion of the Series B Preferred Stock into shares of Common Stock:

         a. General. Subject to and in compliance with the provisions of this
Section 4, all but not less than all of the shares of the Series B Preferred
Stock may, at the option of the holder, be converted at any time into fully paid
and non-assessable shares of Common Stock. As of the date hereof, the number of
shares of Common Stock to which a holder of each share of Series B Preferred
Stock shall be entitled upon conversion is 41.3223, which number is derived by
dividing $1000.00 by $24.20 (the "Series B Applicable Conversion Value"), which
Series B Applicable Conversion Value shall be adjusted from time to time in
accordance with this Section 4.

         b. Adjustments to Series B Applicable Conversion Values.

            (i) (A) Upon Sale of Common Stock. If the Corporation shall, while
there are any shares of Series B Preferred Stock outstanding, issue or sell (or
in accordance with Section 4(b)(i)(B) is deemed to have issued or sold) shares
of its Common Stock without consideration or at a price per share less than the
Series B Applicable Conversion Value, then in each such case such Series B
Applicable Conversion Value for the Series B Preferred Stock upon each such
issuance or sale, except as hereinafter provided, shall be lowered so as to be
equal to an amount determined by multiplying the Series B Applicable Conversion
Value at such time by a fraction:

                    (1) the numerator of which shall be (a) the number of
shares of Common Stock outstanding immediately prior to the issuance of such
additional shares of Common Stock, plus (b) the number of shares of Common Stock
which the net aggregate consideration, if any, received by the Corporation for
the total number of such additional shares of Common Stock so issued would
purchase at the Series B Applicable Conversion Value in effect immediately prior
to such issuance, and

                    (2) the denominator of which shall be (a) the number of
shares of Common Stock outstanding immediately prior to the issuance of such
additional shares of Common Stock plus (b) the number of such additional shares
of Common Stock so issued.

                (B) Upon Issuance of Warrants, Options and Rights to Common
Stock.

                                      -16-


<PAGE>   17


                  (1) For the purposes of this Section 4(b)(i), the issuance
of any warrants, options, subscriptions, or purchase rights with respect to
shares of Common Stock and the issuance of any securities convertible into or
exchangeable for shares of Common Stock (or the issuance of any warrants,
options or any rights with respect to such convertible or exchangeable
securities) shall be deemed an issuance of such Common Stock at such time if
the Series B Net Consideration Per Share (as hereinafter determined) which may
be received by the Corporation for such Common Stock shall be less than the
Series B Applicable Conversion Value at such time. Any obligation, agreement,
or undertaking to issue warrants, options, subscriptions, or purchase rights at
any time in the future shall be deemed to be an issuance at the time such
obligation, agreement or undertaking is made or arises. No adjustment of the
Series B Applicable Conversion Value shall be made under this Section 4(b)(i)
upon the issuance of any shares of Common Stock which are issued pursuant to
the exercise of any warrants, options, subscriptions, or purchase rights or
pursuant to the exercise of any conversion or exchange rights in any
convertible securities if any adjustment shall previously have been made or
deemed not required hereunder, upon the issuance of any such warrants, options,
or subscription or purchase rights or upon the issuance of any convertible
securities (or upon the issuance of any warrants, options or any rights
therefor) as provided above.

Should the Series B Net Consideration Per Share of any such warrants, options,
subscriptions or purchase rights or convertible securities be decreased from
time to time, then, upon the effectiveness of each such change, the Series B
Applicable Conversion Value shall be adjusted to such Series B Applicable
Conversion Value as would have obtained (1) had the adjustments made upon the
issuance of such warrants, options, rights, or convertible securities been made
upon the basis of the decreased Series B Net Consideration Per Share of such
securities, and (2) had adjustments made to the Series B Applicable Conversion
Value since the date of issuance of such securities been made to the Series B
Applicable Conversion Value as adjusted pursuant to (1) above.

                  (2) For purposes of this paragraph, the "Series B Net
Consideration Per Share" which may be received by the Corporation shall be
determined as follows:

                      I. The "Series B Net Consideration Per Share" shall mean
the amount equal to the total amount of consideration, if any, received by the
Corporation for the issuance of such warrants, options, subscriptions, or other
purchase rights or convertible or exchangeable securities, plus the minimum
amount of consideration, if any, payable to the Corporation upon exercise or
conversion thereof, divided by the aggregate number of shares of Common Stock
that would be issued if all such warrants, options, subscriptions, or other
purchase rights or convertible or exchangeable securities were exercised,
exchanged, or converted.

                      II. The "Series B Net Consideration Per Share" which may
be received by the Corporation shall be determined in each instance as of the
date of issuance of warrants, options, subscriptions, or other purchase rights
or convertible or exchangeable securities without giving effect to any possible
future upward price adjustments or rate adjustments which may be applicable with
respect to such warrants, options, subscriptions, or other purchase rights or
convertible or exchangeable securities.

                                      -17-

<PAGE>   18

                      (C) Stock Dividends. In the event the Corporation shall
make or issue a dividend or other distribution payable in Common Stock or
securities of the Corporation convertible into or otherwise exchangeable for the
Common Stock of the Corporation, then such Common Stock or other securities
issued in payment of such dividend shall be deemed to have been issued without
consideration (except for dividends payable in shares of Common Stock payable
pro rata to holders of Series B Preferred Stock and to holders of any other
class of stock).

                      (D) Consideration Other than Cash. For purposes of this
Section 4(b), if a part or all of the consideration received by the
Corporation in connection with the issuance of shares of the Common Stock or the
issuance of any of the securities described in this Section 4(b) consists of
property other than cash, such consideration shall be deemed to have a fair
market value as is reasonably determined in good faith by the Board.

                      (E) Exceptions. This Section 4(b)(i) shall not apply under
any of the circumstances which would constitute an Extraordinary Common Stock
Event (as hereinafter defined in Section 4(b)(ii)). Further, the provisions of
this Section 4(b) shall not apply to (i) shares issued upon conversion of the
Series B Preferred Stock, (ii) the issuance of any Common Stock pursuant to the
exercise of the options (and the shares issuable upon exercise thereof) to
purchase up to an aggregate of 140,000 shares of Common Stock (excluding options
outstanding on the date hereof) issued to employees of the Corporation, or (iii)
the issuance of warrants to the Corporation's lenders in connection with that
certain Warrant Agreement among the Corporation, Merrill Lynch & Co., Merrill
Lynch, Pierce, Fenner & Smith Incorporated, PNC Bank, National Association, and
certain other holders party thereto, dated as of February 26, 1999. The number
of shares in this Section (E) shall be proportionately adjusted to reflect any
stock dividend, stock split or other form of recapitalization occurring after
the date hereof.

                  (ii) Upon Extraordinary Common Stock Event. Upon the
happening of an Extraordinary Common Stock Event, the Series B Applicable
Conversion Value for the Series B Preferred Stock shall, simultaneously with the
happening of such Extraordinary Common Stock Event, be adjusted by multiplying
the then effective Series B Applicable Conversion Value with respect to the
Series B Preferred Stock by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such
Extraordinary Common Stock Event and the denominator of which shall be the
number of shares of Common Stock outstanding immediately after such
Extraordinary Common Stock Event, and the product so obtained shall
thereafter be the Series B Applicable Conversion Value. The Series B Applicable
Conversion Value for the Series B Preferred Stock shall be readjusted in the
same manner upon the happening of any successive Extraordinary Common Stock
Event or Events.

                  (iii) Failure to Effectuate Series B Qualified Public Offering
by March 1, 2002. In the event the Corporation has not effected a Series B
Qualified Public Offering by March 1, 2002, and it has not sold substantially
all of its assets or stock by such date, the Series B Applicable Conversion
Value shall be deemed to have been, as of the date hereof, $35.00, and any

                                      -18-

<PAGE>   19


adjustments to the Series B Applicable Conversion Value made after the date
hereof shall be made to such number.

                  c. Dividends. In the event the Corporation shall make or
issue, or shall fix a record date for the determination of holders of Common
Stock entitled to receive, a dividend or other distribution with respect to the
Common Stock payable in (i) securities of the Corporation other than shares of
Common Stock or (ii) assets, then and in each such event the holders of Series B
Preferred Stock shall receive, at the same time such distribution is made with
respect to Common Stock, the number of securities or such other assets of the
Corporation which they would have received had their Series B Preferred Stock
been converted into Common Stock immediately prior to the date of such
distribution.

                  d. Capital Reorganization or Reclassification. If the Common
Stock issuable upon the conversion of the Series B Preferred Stock shall be
changed into the same or different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision or combination of shares or stock dividend provided for
elsewhere in this Section 4 or by a Reorganization), then and in each such
event, the holder of each share of Series B Preferred Stock shall have the
right thereafter to convert such share into the kind and amount of shares of
stock and other securities and property receivable upon such capital
reorganization, reclassification or other change by holders of the number of
shares of Common Stock into which such shares of Series B Preferred Stock might
have been converted immediately prior to such capital reorganization,
reclassification or other change.

                  e. Capital Reorganization, Merger or Sale of Assets. If at
any time or from time to time there shall be a capital reorganization of the
Common Stock (other than a subdivision, combination, reclassification or
exchange of shares provided for elsewhere in this Section 4) or a
Reorganization, then as a part of such Reorganization, provision shall be made
so that the holders of the Series B Preferred Stock shall thereafter be entitled
to receive upon conversion of the Series B Preferred Stock, the number of shares
of stock or other securities or property of the Corporation, or of the successor
corporation resulting from such Reorganization, to which such holder would have
been entitled if such holder had converted its shares of Series B Preferred
Stock immediately prior to such Reorganization. In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 4
with respect to the rights of the holders of the Series B Preferred Stock after
the Reorganization, to the end that the provisions of this Section 4 (including
adjustment of the Series B Applicable Conversion Value then in effect and the
number of shares issuable upon conversion of the Series B Preferred Stock) shall
be applicable after that event in as nearly equivalent a manner as may be
practicable.

                  f. Certificate as to Adjustments; Notice by Corporation. In
each case of an adjustment or readjustment of the Applicable Conversion Rate,
the Corporation at its expense will furnish each holder of Series B Preferred
Stock with a certificate, executed by the president and chief financial officer
(or in the absence of a person designated as the chief financial officer, by
the treasurer) showing such adjustment or readjustment, and stating in detail
the facts upon which such adjustment or readjustment is based.

                                      -19-

<PAGE>   20





                  g. Exercise of Conversion Privilege. To exercise its
conversion privilege, a holder of Series B Preferred Stock shall surrender the
certificate or certificates representing the shares being converted to the
Corporation at its principal office, and shall give written notice to the
Corporation at that office that such holder elects to convert such shares. Such
notice shall also state the name or names (with address or addresses) in which
the certificate or certificates for shares of Common Stock issuable upon such
conversion shall be issued. The certificate or certificates for shares of Series
B Preferred Stock surrendered for conversion shall be accompanied by proper
assignment thereof to the Corporation or in blank. The date when such written
notice is received by the Corporation, together with the certificate or
certificates representing the shares of Series B Preferred Stock being
converted, shall be the "Series B Conversion Date." As promptly as practicable
after the Series B Conversion Date, the Corporation shall issue and shall
deliver to the holder of the shares of Series B Preferred Stock being converted,
or on its written order, such certificate or certificates as it may request for
the number of whole shares of Common Stock issuable upon the conversion of such
shares of Series B Preferred Stock in accordance with the provisions of this
Section 4, and cash, as provided in Section 4(h), in respect of any fraction of
a share of Common Stock issuable upon such conversion. Such conversion shall be
deemed to have been effected immediately prior to the close of business on the
Series B Conversion Date, and at such time the rights of the holder as holder of
the converted shares of Series B Preferred Stock shall cease and the person or
persons in whose name or names any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become the holder or holders of record of the shares of Common Stock represented
thereby. The Corporation shall pay any taxes payable with respect to the
issuance of Common Stock upon conversion of the Series B Preferred Stock, other
than any taxes payable with respect to income by the holders thereof.

                  h. Cash in Lieu of Fractional Shares. The Corporation may, if
it so elects, issue fractional shares of Common Stock or scrip representing
fractional shares upon the conversion of shares of Series B Preferred Stock. If
the Corporation does not elect to issue fractional shares, the Corporation shall
pay to the holder of the shares of Series B Preferred Stock which were converted
a cash adjustment in respect of such fractional shares in an amount equal to the
same fraction of the market price per share of the Common Stock (as determined
in a reasonable manner prescribed by the Board) at the close of business on the
Series B Conversion Date. The determination as to whether or not any fractional
shares are issuable shall be based upon the total number of shares of Series B
Preferred Stock being converted at any one time by any holder thereof, not upon
each share of Series B Preferred Stock being converted.

                  i. Reservation of Common Stock. The Corporation shall at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock, solely for the purpose of effecting the conversion of the shares
of the Series B Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series B Preferred Stock, and if at any time the
number of authorized but unissued shares of Common Stock shall not be sufficient
to effect the conversion of all then outstanding shares of the Series B
Preferred Stock, the Corporation shall take such corporate action as may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purpose.

                                      -20-

<PAGE>   21
         Section 5. No Reissuance of Series B Preferred Stock. No share or
shares of Series B Preferred Stock acquired by the Corporation by reason of
redemption, purchase, conversion or otherwise shall be reissued, and all such
shares shall be canceled, retired and eliminated from the shares which the
Corporation shall be authorized to issue. The Corporation may from time to
time take such appropriate corporate action as may be necessary to reduce the
authorized number of shares accordingly.

         Section 6. Redemption.

         a. Optional Redemption Upon Series B Qualified Public Offering.
Effective upon the closing of a Series B Qualified Public Offering, the
Corporation may require the holders of the Series B Preferred Stock to convert
their Series B Preferred Stock into Common Stock by sending notice thereof,
together with a calculation of the Series B Applicable Conversion Value, at
least ten business days prior to the closing of the Series B Qualified Public
Offering, to all holders of Series B Preferred Stock. The mandatory conversion
shall be effective as of the closing date of the Series B Qualified Public
Offering and on and after such date the certificates representing the Series B
Preferred Stock shall only represent the right to receive the Conversion
Shares. For purposes hereof, the term "Series B Qualified Public Offering"
shall mean an underwritten public offering pursuant to an effective
registration statement under the Securities Act, covering the offer and sale of
Common Stock for the account of the Corporation in which the aggregate net
proceeds to the Corporation equal at least $25,000,000 and in which the price
per share of Common Stock is at least two and one half (2.5) times the then
Series B Applicable Conversion Value of the Series B Preferred Stock. Nothing
contained in Section 6(a) shall (i) in any way restrict or prohibit the holders
of the Series B Preferred Stock from exercising their conversion rights
pursuant to Section 4 hereof prior to the effective date of the redemption to
be effected hereunder; provided, however, that any such conversion under
Section 6(a) may be subject to the closing of the Series B Qualified Public
Offering.

         b. Optional Redemption by a Holder Following Default.

                  (i) In the event there is a Default, then the holders of at
least fifty-one percent (51%) of the then outstanding shares of Series B
Preferred Stock may request the Corporation to redeem any or all of the shares
of Series B Preferred Stock then held by such holders at the price equal to the
greater of (i) the original purchase price of the Series B Preferred Stock (as
adjusted to reflect any stock split, stock dividend or other form of
recapitalization), together with all accrued and unpaid dividends (whether or
not declared) thereon to be calculated and paid through and including the date
of redemption or (ii) fair market value thereof, as of the date of such
proposed redemption, as determined, at the Corporation's sole expense, by a
nationally recognized investment banking firm (mutually acceptable to both the
Corporation and the holders), taking into account, in valuing such Shares, all
relevant facts and circumstances; provided, however, that there shall be no
discount to reflect the fact that the Shares represent a minority interest in
the Corporation (the "Holder Redemption Price"). Such request (the "Default
Redemption Request") shall be submitted to the Corporation in writing within
thirty (30) days after the Corporation notifies all of the holders of the
Series B Preferred Stock in writing of the Default. No cure of such Default
during such thirty

                                     - 21 -
<PAGE>   22

(30) day period shall vitiate such Default Redemption Request and the failure to
make such a Default Redemption Request within such thirty (30) day period shall
not result in the waiver of such remedy.

                  (ii) Upon receipt of a Default Redemption Request, the
Corporation shall promptly give notice thereof (the "Default Redemption Notice")
to each holder of Series B Preferred Stock. Such Default Redemption Notice shall
specify the number of shares of Series B Preferred Stock covered by the Default
Redemption Request and the Holder Redemption Price to be paid with respect
thereto. Any holder of Series B Preferred Stock who wishes to join in the
Default Redemption Request may do so by so advising the Corporation in writing
within 15 days after receipt of the Default Redemption Notice specified in the
preceding sentence. No holder of Series B Preferred Stock shall be required to
participate in such redemption. The Corporation shall redeem all shares of
Series B Preferred Stock covered by the Default Redemption Request (including
those held by holders who have requested a redemption following receipt of
the Default Redemption Notice) at a closing to be held not more than thirty (30)
days after the date of the Default Redemption Request. At the closing, the
Corporation shall pay for the shares of Series B Preferred Stock so redeemed in
an amount equal to the Holder Redemption Price, payable in cash.

         c. Optional Redemption by Holders. At the election of the holders of at
least fifty-one percent (51%) of the then outstanding shares of Series B
Preferred Stock, the Corporation shall, to the extent it may do so under
applicable law, redeem pro rata from all holders of Series A Preferred Stock on
April 15, 2005 the Shares of Series B Preferred Stock outstanding on the date of
such redemption (the "Final Redemption Date"). The Corporation shall give the
holders of the Series B Preferred Stock at least ninety (90) days' notice of the
Final Redemption Date (the "Final Redemption Notice"). In the event that the
Corporation does not provide the Final Redemption Notice, the option of the
holders of the Series B Preferred Stock to require the Corporation to redeem the
remaining shares of Series B Preferred Stock on the Final Redemption Date shall
be extended beyond the Final Redemption Date to a date which is ninety (90) days
from the date that the Corporation elects to mail the Final Redemption Notice.
In the event shares of Series B Preferred Stock scheduled for redemption are not
redeemed because of a prohibition under applicable law, such shares shall be
redeemed as soon as such prohibition no longer exists. The redemption price for
each share of Series B Preferred Stock redeemed pursuant to this Section 6(c)
shall be equal to the Holder Redemption Price.

         In the event that the holders of the Series B Preferred Stock do not
elect to have the Series B Preferred Stock redeemed pursuant to this Section
6(c), the shares of Series B Preferred Stock shall remain outstanding and
subject to the rights and preferences contained herein.

         d. Redemption Notice. If an election is made pursuant to Section 6(c)
hereof, written notice of such election shall be mailed, postage prepaid, to the
Corporation, not later than sixty (60) days before the date fixed for each
redemption pursuant to Section 6(c) or, in the event the Corporation does not
provide the Final Redemption Notice pursuant to Section 6(c) hereof, not later
than sixty (60) days before the date that the Final Redemption Date has been
extended as provided in Section 6(c) (each of the dates fixed for redemption and
the extended redemption date is hereinafter referred to as a "Redemption
Date"). If such election is made and appropriate notice is

                                     - 22 -
<PAGE>   23


given, then, at least forty-five (45) days before the Redemption Date, written
notice (hereinafter referred to as the "Redemption Notice") shall be mailed by
the Corporation, postage prepaid, to each holder of record of Series B Preferred
Stock at its address shown on the records of the Corporation; provided, however,
that the Corporation's failure to give such Redemption Notice shall in no way
affect its obligation to redeem the shares of Series B Preferred Stock or the
obligation of the holders to redeem their shares of Series B Preferred Stock as
provided in Section 6(c) hereof. The Redemption Notice shall contain (i) the
number of shares of Series B Preferred Stock held by the holder and the total
number of shares of Series B Preferred Stock held by all holders subject to
redemption as of such Redemption Date; and (ii) the Redemption Date and the
applicable Holder Redemption Price. Any holder of Series B Preferred Stock who
wishes to do so may, by giving notice to the Corporation prior to the Redemption
Date, convert into Common Stock any or all of the shares of Series B Preferred
Stock held by him and scheduled for redemption on such Redemption Date.

         e. Surrender of Certificates. Each holder of shares of Series B
Preferred Stock to be redeemed under this Section 6 shall surrender the
certificate or certificates representing such shares to the Corporation at the
place designated in the Redemption Notice, and thereupon the Corporation
Redemption Price or Holder Redemption Price, as the case may be, for such shares
as set forth in this Section 6 shall be paid to the order of the person whose
name appears on such certificate or certificates. Irrespective of whether the
certificates therefor shall have been surrendered, all shares of Series B
Preferred Stock which are the subject of a Redemption Notice shall be deemed to
have been redeemed and shall be canceled effective as of the Redemption Date,
unless the Corporation shall default in the payment of the applicable Redemption
Price.

         f. Sale of the Corporation. In lieu of the redemption obligations of
the Corporation as set forth herein, the Corporation may instead retain a
nationally recognized investment banking firm (or other mutually acceptable
party) to sell the Corporation, provided that the Corporation acts expeditiously
and in good faith and the sale of the Corporation is consummated no later than
180 days after the required date of redemption.


         Section 7. Restrictions and Limitations.

         a. Corporate Securities Action. Except as expressly provided herein or
as otherwise required by law, so long as any shares of Series B Preferred Stock
remain outstanding, the Corporation shall not, and shall not permit any
subsidiary (which shall mean any corporation, association or other business
entity which the Corporation and/or any of its other subsidiaries directly or
indirectly owns at the time more than fifty percent (50%) of the outstanding
voting shares of such corporation or trust, other than directors' qualifying
shares) to, without the approval by vote or written consent by the holders of at
least a majority of the then outstanding shares of the Corporation's Series A
Preferred Stock and the Series B Preferred Stock, voting as a separate class:

                  (i) redeem, purchase or otherwise acquire for value (or pay
into or set aside for a sinking fund for such purpose), or declare and pay or
set aside funds for the payment of


                                      -23-
<PAGE>   24


any dividend with respect to, any share or shares of capital stock, except as
required or permitted hereunder or under the terms of Section 4.2 of the
Subscription Agreement;

                  (ii) authorize or issue, or obligate itself to authorize or
issue, additional shares of Series B Preferred Stock;

                  (iii) authorize or issue, or obligate itself to authorize or
issue, any equity security senior to or on parity with the Series B Preferred
Stock as to liquidation preferences, dividend rights, or voting rights;

                  (iv) merge or consolidate with any other corporation or sell,
assign, lease or otherwise dispose of or voluntarily part with the control of
(whether in one transaction or in a series of transactions) all, of
substantially all, of its assets (whether now owned or hereinafter acquired), or
consent to any liquidation, dissolution or winding up of the Corporation, or
permit any subsidiary to do any of the foregoing, except for (A) any
wholly-owned subsidiary may merge into or consolidate with or transfer assets to
any other wholly-owned subsidiary, and (B) any wholly-owned subsidiary may merge
into or transfer assets to the Corporation; or

                  (v) amend, restate, modify or alter the by-Laws of the
Corporation in any way which adversely affects the rights of the holders of the
Series B Preferred Stock.

         b. Amendments to Charter. The Corporation shall not amend its Articles
of Incorporation without the approval, by vote or written consent, by the
holders of at least a majority of the then outstanding shares of Series B
Preferred Stock, if such amendment would amend any of the rights, preferences,
privileges of or limitations provided for herein for the benefit of any shares
of Series B Preferred Stock. Without limiting the generality of the preceding
sentence, the Corporation shall not amend its Articles of Incorporation without
the approval by the holders of at least a majority of the then outstanding
shares of Series B Preferred Stock if such amendment would:

                  (i) change the relative seniority rights of the holders of
Series B Preferred Stock as to the payment of dividends in relation to the
holders of any other capital stock of the Corporation, or create any other class
or series of capital stock entitled to seniority as to the payment of dividends
in relation to the holders of Series B Preferred Stock;

                  (ii) reduce the amount payable to the holders of Series B
Preferred Stock upon the voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, or change the relative seniority of the
liquidation preferences of the holders of Series B Preferred Stock to the rights
upon liquidation of the holders of other capital stock of the Corporation, or
change the dividend rights of the holders of Series B Preferred Stock;

                  (iii) cancel or modify the conversion rights of the holders of
Series B Preferred Stock provided for in Section 4 herein;


                                     -24-
<PAGE>   25




                  (iv) cancel or modify the redemption rights of the holders of
the Series B Preferred Stock provided for in Section 6 herein; or

                  (v) cancel or modify the rights of the holders of the Series
B Preferred Stock provided for in this Section 7.


         Section 8. No Dilution or impairment. The Corporation shall not, by
amendment of its Articles of Incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of the Series B Preferred Stock set forth
herein, but shall at all times in good faith assist in the carrying out of all
such terms in the taking of all such actions as may be necessary or appropriate
in order to protect the rights of the holders of the Series B Preferred Stock
against dilution or other impairment. Without limiting the generality of the
foregoing, the Corporation (a) shall not increase the par value of any shares of
stock receivable on the conversion of the Series B Preferred Stock above the
amount payable therefor on such conversion, (b) shall take all such action as
may be necessary or appropriate in order that the Corporation may validly and
legally issue fully paid and nonassessable shares of stock on the conversion
of all Series B Preferred Stock from time to time outstanding, and (c) shall
not consolidate with or merge into any other person or permit any such person to
consolidate with or merge into the Corporation (if the Corporation is not the
surviving person), unless such other person shall expressly assume in writing
and will be bound by all of the terms of the Series B Preferred Stock set forth
herein.

         Section 9. Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution, or any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, or

         a. any capital reorganization of the Corporation, any reclassification
or recapitalization of the capital stock of the Corporation, any merger of the
Corporation, or any transfer of all or substantially all of the assets of the
Corporation to any other corporation, or any other entity or person, or

         b. any voluntary or involuntary dissolution, liquidation or winding up
of the Corporation,

then and in each such event the Corporation shall mail or cause to be mailed to
each holder of Series B Preferred Stock a notice specifying (i) the date on
which any such record is to be taken for the purpose of such dividend,
distribution or right and a description of such dividend, distribution or right,
(ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, merger, dissolution, liquidation or winding up is
expected to become effective, and (iii) the time, if any, that is to be fixed,
as to when the holders of record of Common Stock (or other securities) shall be
entitled to exchange their shares of Common Stock (or other securities) for
securities or other


                                      -25-
<PAGE>   26


property deliverable upon such reorganization, reclassification,
recapitalization, transfer, merger, dissolution, liquidation or winding up. Such
notice shall be mailed at least ten (10) business days prior to the date
specified in such notice on which such action is to be taken.

III. Series C Participating Preferred.

         Section 1. Dividends.

         a. General Obligation in Respect of Preferential Dividends. When and as
declared by the Board and to the extent permitted under the Florida Business
Corporation Act, the Corporation shall pay preferential dividends in cash to the
holders of the Series C Preferred as provided in this Section 1. Dividends on
each share of the Series C Participating Preferred (a Series C Participating
Preferred Share") shall accrue on a daily basis at the rate of 12% per annum of
the sum of the Series C Liquidation Value thereof plus all accumulated and
unpaid dividends thereon from and including the date of issuance of such Series
C Participating Preferred Share to and including the first to occur of (i) the
date on which the Series C Liquidation Value of such Series C Participating
Preferred Share (plus all accrued and unpaid dividends thereon) is paid to the
holder thereof in connection with the liquidation of the Corporation or the
redemption of such Series C Participating Preferred Share by the Corporation or
otherwise (but excluding any amounts paid pursuant to paragraph (d)
below), (ii) the date on which such Series C Participating Preferred Share is
converted into shares of Series C Conversion Stock hereunder or (iii) the date
on which such Series C Participating Preferred Share is otherwise acquired by
the Corporation. Such dividends shall accrue whether or not they have been
declared and whether or not there are profits, surplus or other funds of the
Corporation legally available for the payment of dividends, and such dividends
shall be cumulative such that all accrued and unpaid dividends shall be fully
paid or declared with funds irrevocably set apart for payment before any
dividends, distributions, redemptions or other payments may be made with respect
to any Junior Securities. The date on which the Corporation initially issues any
Series C Participating Preferred Share shall be deemed to be its "date of
issuance" regardless of the number of times transfer of such Series C
Participating Preferred Share is made on the stock records maintained by or for
the Corporation and regardless of the number of certificates which may be issued
to evidence such Series C Participating Preferred Share.

         b. Dividend Reference Dates. To the extent not paid on March 31, June
30, September 30 and December 31 of each year, beginning December 31, 1999 (the
"Dividend Reference Dates"), all dividends which have accrued on each Series C
Participating Preferred Share outstanding during the three-month period (or
other period in the case of the initial Dividend Reference Date) ending upon
each such Dividend Reference Date shall be accumulated and shall remain
accumulated dividends with respect to such Series C Participating Preferred
Share until paid to the holder thereof.

         c. Distribution of Partial Dividend Payments. Except as otherwise
provided herein, if at any time the Corporation pays less than the total amount
of dividends then accrued with respect to the Series C Participating Preferred,
such payment shall be distributed pro rata among the


                                     - 26 -
<PAGE>   27


holders thereof based upon the aggregate accrued but unpaid dividends on the
Series C Participating Preferred Shares held by each such holder.

         d. Participating Dividends. In the event that the Corporation declares
or pays any dividends upon the Common Stock (whether payable in cash, securities
or other property) other than dividends payable solely in shares of Common
Stock, the Corporation shall also declare and pay to the holders of the Series C
Participating Preferred at the same time that it declares and pays such
dividends to the holders of the Common Stock, the dividends which would have
been declared and paid with respect to the Common Stock issuable upon conversion
of the Series C Participating Preferred had all of the outstanding Series C
Participating Preferred been converted immediately prior to the record date for
such dividend, or if no record date is fixed, the date as of which the record
holders of Common Stock entitled to such dividends are to be determined.


         Section 2. Liquidation.

         Upon any liquidation, dissolution or winding up of the Corporation
(whether voluntary or involuntary), each holder of Series C Participating
Preferred shall be entitled to be paid, (i) before any distribution or payment
is made upon any Junior Securities an amount in cash equal to the aggregate
Series C Liquidation Value of all Series C Participating Preferred Shares held
by such holder (plus all accrued and unpaid dividends thereon), and (ii) an
amount in cash equal to its ratable share on a per share basis of all
distributions to the holders of Common Stock which would have been payable with
respect to the Common Stock issuable upon conversion of the Series C
Participating Preferred had all of the outstanding Series C Participating
Preferred been converted immediately prior to such liquidation, dissolution or
winding up of the Corporation. If upon any such liquidation, dissolution or
winding up of the Corporation the Corporation's assets to be distributed among
the holders of the Series C Participating Preferred are insufficient to permit
payment to such holders of the aggregate amount which they are entitled to be
paid under this Section 2, then the entire assets available to be distributed to
the Corporation's stockholders shall be distributed pro rata among such holders
based upon the aggregate Series C Liquidation Value (plus all accrued and unpaid
dividends) of the Series C Participating Preferred held by each such holder. Not
less than 60 days prior to the payment date stated therein, the Corporation
shall mail written notice of any such liquidation, dissolution or winding up to
each record holder of Series C Participating Preferred, setting forth in
reasonable detail the amount of proceeds to be paid with respect to each share
of Series C Preferred Stock and the Common Stock in connection with such
liquidation, dissolution or winding up.

         Section 3. Priority of Series C Participating Preferred on Dividends
                    and Redemptions.

         So long as any Series C Participating Preferred remains outstanding,
without the prior written consent of the holders of a majority of the
outstanding shares of Series C Participating Preferred, the Corporation shall
not, nor shall it permit any Subsidiary to, redeem, purchase or otherwise
acquire directly or indirectly any Junior Securities, nor shall the Corporation
directly or indirectly pay or declare any dividend or make any distribution upon
any Junior Securities, if at the


                                     - 27 -
<PAGE>   28


time of or immediately after any such redemption, purchase, acquisition,
dividend or distribution the Corporation has failed to pay the full amount of
dividends accrued on the Series C Participating Preferred or the Corporation has
failed to make any redemption of the Series C Participating Preferred required
hereunder; provided that the Corporation may repurchase shares of Common Stock
from present or former employees of the Corporation and its Subsidiaries in
accordance with the arrangements and agreements which have been approved by the
Board.

         Section 4. Redemptions.

         a. Scheduled Redemptions. The Corporation shall redeem all of the
outstanding Series C Participating Preferred Shares on December 31, 2019 (the
"Scheduled Redemption Date"), at a price per Series C Participating Preferred
Share equal to the Series C Redemption Price. For purposes hereof, the "Series C
Redemption Price" of any Series C Participating Preferred Share at any time
shall mean the aggregate amount to which the holder of such share would be
entitled pursuant to Section 2 above if the Corporation were liquidated at such
time.

         b. Redemption Payments. For each Series C Participating Preferred Share
which is to be redeemed hereunder, the Corporation shall be obligated on the
Scheduled Redemption Date to pay to the holder thereof (upon surrender by such
holder at the Corporation's principal office of the certificate representing
such Series C Participating Preferred Share) an amount in immediately available
funds equal to the Series C Redemption Price of such Series C Participating
Preferred Share. If the funds of the Corporation legally available for
redemption of Series C Participating Preferred Shares on the Scheduled
Redemption Date are insufficient to redeem the total number of Series C
Participating Preferred Shares to be redeemed on such date, those funds which
are legally available shall be used to redeem the maximum possible number
of Series C Participating Preferred Shares pro rata among the holders of the
Series C Participating Preferred Shares to be redeemed, first based upon the
aggregate Series C Liquidation Value of such Series C Participating Preferred
Shares held by each such holder (plus all accrued and unpaid dividends thereon),
and after such time as distributions have been paid in such amounts, then based
upon holdings of Series C Participating Preferred. At any time thereafter when
additional funds of the Corporation are legally available for the redemption of
Series C Participating Preferred Shares, such funds shall immediately be used to
redeem the balance of the Series C Participating Preferred Shares which the
Corporation has become obligated to redeem on the Scheduled Redemption Date but
which it has not redeemed.

         c. Notice of Redemption. Except as otherwise provided herein, the
Corporation shall mail written notice of each redemption of any Series C
Participating Preferred to each record holder thereof not more than 60 nor less
than 30 days prior to the date on which such redemption is to be made. In case
fewer than the total number of Series C Participating Preferred Shares
represented by any certificate are redeemed, a new certificate representing the
number of unredeemed Series C Participating Preferred Shares shall be issued to
the holder thereof without cost to such holder within five business days after
surrender of the certificate representing the redeemed Series C Participating
Preferred Shares.


                                      -28-
<PAGE>   29


         d. Determination of the Number of Each Holder's Series C Participating
Preferred Shares to be Redeemed. Except as otherwise provided herein, the number
of Series C Participating Preferred Shares to be redeemed from each holder
thereof in redemptions hereunder shall be the number of Series C Participating
Preferred Shares determined by multiplying the total number of Series C
Participating Preferred Shares to be redeemed times a fraction, the numerator of
which shall be the total number of Series C Participating Preferred Shares then
held by such holder and the denominator of which shall be the total number of
Series C Participating Preferred Shares then outstanding.

         e. Dividends After Scheduled Redemption Date. No Series C Participating
Preferred Share shall be entitled to any dividends accruing after the date on
which the Series C Redemption Price of such Series C Participating Preferred
Share is paid to the holder of such Series C Participating Preferred Share. On
such date, all rights of the holder of such Series C Participating Preferred
Share to receive dividends or other payments shall cease.

         f. Redeemed or Otherwise Acquired Series C Participating Preferred
Shares. Any Series C Participating Preferred Shares which are redeemed or
otherwise acquired by the Corporation shall be canceled and retired to
authorized but unissued shares and shall not be reissued, sold or transferred.


         Section 5. Voting Rights.


         Except as otherwise required by applicable law, each holder of Series C
Participating Preferred Shares shall be entitled to vote, together with the
holders of Series A Preferred, Series B Preferred, Series D Preferred and the
Common Stock as a single class, on all matters to be voted upon by the
shareholders of the Corporation, and in each such vote shall be entitled to that
number of votes (including fractions thereof) equal to the quotient determined
by dividing the aggregate Series C Liquidation Value of the shares so held by
the Common Stock Value Per Share (as defined in the Reorganization Agreement),
except as otherwise required by applicable law.


         Section 6. Conversion.

         a. Conversion Procedure.

                      (i) If an IPO is proposed to occur, the Corporation shall
give written notice of such IPO, describing in reasonable detail the material
terms and date of consummation thereof to each holder of Series C Participating
Preferred not more than 45 days nor less than 20 days prior to the consummation
of such IPO and the Corporation shall give each holder of Series C Participating
Preferred prompt written notice of any material change in the terms or timing of
such transaction. The holder or holders of a majority of the Series C
Participating Preferred then outstanding may cause each holder of Series C
Participating Preferred to convert all or any portion of the Series C
Participating Preferred (including any fraction of a Series C Participating
Preferred Share) held by such holder into shares of Class B Common (or, if no
shares of Class B Common are then outstanding, Common Stock) and shares of Class
D Preferred, with the shares of Series C


                                     - 29 -
<PAGE>   30


Participating Preferred held by each holder converting into (A) the number of
shares of Series D Preferred (or fraction thereof) with Series D Liquidation
Value equal to the aggregate Series C Liquidation Value of, plus the aggregate
amount of accrued and unpaid dividends on, such shares of Series C Participating
Preferred so converted, and (B) the number of shares of Class B Common (or, if
no shares of Class B Common are then outstanding, Common Stock) computed by
dividing the aggregate Series C Liquidation Value of the Series C Participating
Preferred Shares to be converted by such holder by the Conversion Price set
forth in paragraph (b) below then in effect.

                  (ii) Except as otherwise provided herein, each conversion of
Series C Participating Preferred shall be deemed to have been effected as of the
close of business on the date on which the certificate or certificates
representing the Series C Participating Preferred to be converted have been
surrendered for conversion at the principal office of the Corporation. At the
time any such conversion has been effected, the rights of the holder of the
Series C Participating Preferred Shares converted as a holder of Series C
Participating Preferred shall cease and the Person or Persons in whose name or
names any certificate or certificates for shares constituting Series C
Conversion Stock are to be issued upon such conversion shall be deemed to have
become the holder or holders of record of the shares constituting Series C
Conversion Stock represented thereby.

                  (iii) The conversion of any Series C Participating Preferred
Shares may, at the election of the holder thereof, be conditioned upon the
consummation of the IPO in which case such conversion shall not be deemed to be
effective until such IPO has been consummated.

                  (iv) As soon as possible after a conversion has been effected
(but in any event within five business days in the case of subparagraph (A)
below), the Corporation shall deliver to the converting holder:

                           (A) a certificate or certificates representing the
number of shares constituting Series C Conversion Stock issuable by reason of
such conversion in such name or names and such denomination or denominations as
the converting holder has specified; and

                           (B) a certificate representing any Series C
Participating Preferred Shares which were represented by the certificate or
certificates delivered to the Corporation in connection with such conversion but
which were not converted.

                  (vi) The issuance of certificates for shares constituting
Series C Conversion Stock upon conversion of Series C Participating Preferred
shall be made without charge to the holders of such Series C Participating
Preferred for any issuance tax in respect thereof or other cost incurred by the
Corporation in connection with such conversion and the related issuance of
shares constituting Series C Conversion Stock. Upon conversion of each Series C
Participating Preferred Share, the Corporation shall take all such actions as
are necessary in order to insure that the Series C Conversion Stock issuable
with respect to such conversion shall be validly issued, fully paid and
nonassessable, free and clear of all taxes, liens, charges and encumbrances with
respect to the issuance thereof.


                                     - 30 -
<PAGE>   31


                  (vii) The Corporation shall not close its books against the
transfer of Series C Participating Preferred or of Series C Conversion Stock
issued or issuable upon conversion of Series C Participating Preferred in any
manner which interferes with the timely conversion of Series C Participating
Preferred. The Corporation shall assist and cooperate with any holder of Series
C Participating Preferred Shares required to make any governmental filings or
obtain any governmental approval prior to or in connection with any conversion
of Series C Participating Preferred Shares hereunder (including, without
limitation, making any filings required to be made by the Corporation).

                  (viii) The Corporation shall at all times reserve and keep
available out of its authorized but unissued shares constituting Series C
Conversion Stock, solely for the purpose of issuance upon the conversion of the
Series C Participating Preferred, such number of shares constituting Series C
Conversion Stock issuable upon the conversion of all outstanding Series C
Participating Preferred. All shares constituting Series C Conversion Stock which
are so issuable shall, when issued, be duly and validly issued, fully paid and
nonassessable and free from all taxes, liens and charges. The Corporation shall
take all such actions as may be necessary to assure that all such shares
constituting Series C Conversion Stock may be so issued without violation of any
applicable law or governmental regulation or any requirements of any domestic
securities exchange upon which shares constituting Series C Conversion Stock may
be listed (except for official notice of issuance which shall be immediately
delivered by the Corporation upon each such issuance). The Corporation shall not
take any action which would cause the number of authorized but unissued shares
constituting Series C Conversion Stock to be less than the number of such shares
required to be reserved hereunder for issuance upon conversion of the Series C
Participating Preferred.

         (b) Conversion Price. The initial Conversion Price shall be equal to
the product of (i) 100 multiplied by (ii) the Orius Common Value Per Share (as
defined in the Reorganization Agreement), multiplied by (iii) the Preferred
Stock Proportion (as defined in the Reorganization Agreement). If the
Corporation at any time subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater number of shares, the Conversion Price in effect
immediately prior to such subdivision shall be proportionately reduced, and if
the Corporation at any time combines (by reverse stock split or otherwise) one
or more classes of its outstanding shares of Common Stock into a smaller number
of shares, the Conversion Price in effect immediately prior to such combination
shall be proportionately increased.



IV. Series D Preferred.

         Section 1. Dividends.

         a. General Obligation. When and as declared by the Corporation's Board
of Directors and to the extent permitted under the Florida Business Corporation
Act, the Corporation shall pay preferential dividends in cash to the holders of
the Series D Preferred as provided in this Section 1. Dividends on each share of
the Series D Preferred (a "Series D Preferred Share") shall accrue on a daily
basis at the rate of 12% per annum of the sum of the Series D Liquidation Value


                                     - 31 -
<PAGE>   32

thereof plus all accumulated and unpaid dividends thereon from and including the
date of issuance of such Series D Preferred Share to and including the first to
occur of (i) the date on which the Series D Liquidation Value of such Series D
Preferred Share (plus all accrued and unpaid dividends thereon) is paid to the
holder thereof in connection with the liquidation of the Corporation or the
redemption of such Series D Preferred Share by the Corporation, or (ii) the date
on which such Series D Preferred Share is otherwise acquired by the
Corporation. Such dividends shall accrue whether or not they have been declared
and whether or not there are profits, surplus or other funds of the Corporation
legally available for the payment of dividends, and such dividends shall be
cumulative such that all accrued and unpaid dividends shall be fully paid or
declared with funds irrevocably set apart for payment before any dividends,
distributions, redemptions or other payments may be made with respect to any
Junior Securities. The date on which the Corporation initially issues any Series
D Preferred Share shall be deemed to be its "date of issuance" regardless of the
number of times transfer of such Series D Preferred Share is made on the stock
records maintained by or for the Corporation and regardless of the number of
certificates which may be issued to evidence such Series D Preferred Share.

         b. Dividend Reference Dates. To the extent not paid on the Dividend
Reference Dates, beginning December 31, 1999, all dividends which have accrued
on each Series D Preferred Share outstanding during the three-month period (or
other period in the case of the initial Dividend Reference Date) ending upon
each such Dividend Reference Date shall be accumulated and shall remain
accumulated dividends with respect to such Series D Preferred Share until paid
to the holder thereof.

         c. Distribution of Partial Dividend Payments. Except as otherwise
provided herein, if at any time the Corporation pays less than the total amount
of dividends then accrued with respect to the Series D Preferred, such payment
shall be distributed pro rata among the holders thereof based upon the aggregate
accrued but unpaid dividends on the Series D Preferred Shares held by each such
holder.

         Section 2. Liquidation.

         Upon any liquidation, dissolution or winding up of the Corporation
(whether voluntary or involuntary), each holder of Series D Preferred shall be
entitled to be paid, before any distribution or payment is made upon any Junior
Securities an amount in cash equal to the aggregate Series D Liquidation Value
of all Series D Preferred Shares held by such holder (plus all accrued and
unpaid dividends thereon), and the holders of Series D Preferred shall not be
entitled to any further payment. If upon any such liquidation, dissolution or
winding up of the Corporation the Corporation's assets to be distributed among
the holders of the Series D Preferred are insufficient to permit payment to such
holders of the aggregate amount which they are entitled to be paid under this
Section 2, then the entire assets available to be distributed to the
Corporation's stockholders shall be distributed pro rata among such holders
based upon the aggregate Series D Liquidation Value (plus all accrued and unpaid
dividends) of the Series D Preferred held by each such holder. Not less than 60
days prior to the payment date stated therein, the Corporation shall mail
written notice of any such liquidation, dissolution or winding up to each record
holder of Series D Preferred, setting


                                     -32-
<PAGE>   33

forth in reasonable detail the amount of proceeds to be paid with respect to
each share of Series D Preferred and the Common Stock in connection with such
liquidation, dissolution or winding up.

         Section 3. Priority of Series D Preferred on Dividends and Redemptions.

         So long as any Series D Preferred Shares remain outstanding, without
the prior written consent of the holders of a majority of the outstanding shares
of Series D Preferred, the Corporation shall not, nor shall it permit any
Subsidiary to, redeem, purchase or otherwise acquire directly or indirectly any
Junior Securities, nor shall the Corporation directly or indirectly pay or
declare any dividend or make any distribution upon any Junior Securities, if at
the time of or immediately after any such redemption, purchase, acquisition,
dividend or distribution the Corporation has failed to pay the full amount of
dividends accrued on the Series D Preferred or the Corporation has failed to
make any redemption of the Series D Preferred required hereunder; provided that
the Corporation may repurchase shares of Common Stock from present or former
employees of the Corporation and its Subsidiaries in accordance with the
arrangements and agreements which have been approved by the Board.

         Section 4. Redemptions.

         a. Scheduled Redemptions. The Corporation shall redeem all of the
outstanding Series D Preferred Shares on the Scheduled Redemption Date, at
a price per Series D Preferred Share equal to the Series D Liquidation Value
thereof (plus all accrued and unpaid dividends thereon), payable in cash.

         b. Optional Redemptions. The Corporation may, to the extent it may do
so under applicable law, redeem all of the outstanding Series D Preferred Shares
at any time and from time to time after the date of initial issuance thereof
and, if so requested by the holders of a majority of the outstanding Series D
Preferred Shares, shall be obligated to redeem all outstanding Series D
Preferred Shares or such lesser amount or proportion thereof as such holders may
request at any time or from time to time. Upon any such redemption, the
Corporation shall pay a price per Series D Preferred Share equal to the Series D
Liquidation Value thereof (plus all accrued and unpaid dividends thereon);
provided that the Corporation (i) shall pay the purchase price in any such
redemption in Common Stock of the Corporation if the payment of cash or other
funds in any such redemption is prohibited by, or would otherwise violate the
terms of any agreement or instrument evidencing, securing or relating to any
indebtedness of the Corporation or any of its direct or indirect subsidiaries in
excess of $5,000,000 in the aggregate, and (ii) so long as clause (i) above is
not applicable, may unless the holders of a majority of the outstanding Series D
Preferred otherwise object, elect to pay the purchase price in any such
redemption in Common Stock of the Corporation. In such event, the Corporation
shall issue to each holder of Series D Preferred Shares which are subject to
redemption a number of shares of Common Stock with fair market value equal to
the Series D Liquidation Value thereof (plus all accrued and unpaid dividends
thereon). If any such redemption of Series D Preferred is consummated
contemporaneously with a public offering by the Corporation of shares of its
Common Stock, the fair market value of the Common Stock will be conclusively
presumed for the purposes hereof to be equal to price per share at which the


                                      -33-
<PAGE>   34


Corporation sells such shares [(net of underwriting discounts)], and otherwise
shall be determined by the Board in good faith; provided that if the holders of
a majority of the outstanding Series D Preferred Shares object to the valuation
so determined by the Board, such fair market value shall be determined by
agreement between the Board and such holders. If such parties are unable to
reach agreement within a reasonable period of time, such fair value shall be
determined by an appraiser jointly selected by the Corporation and the holders
of a majority of the outstanding Series D Preferred Shares.

         c. Redemption Payments. For each Series D Preferred Share which is to
be redeemed hereunder, the Corporation shall be obligated on the Scheduled
Redemption Date to pay to the holder thereof (upon surrender by such holder at
the Corporation's principal office of the certificate representing such Series D
Preferred Share) an amount in immediately available funds equal to the Series D
Liquidation Value of such Series D Preferred Share (plus all accrued and unpaid
dividends thereon). If the funds of the Corporation legally available for
redemption of Series D Preferred Shares on the Scheduled Redemption Date are
insufficient to redeem the total number of Series D Preferred Shares to be
redeemed on such date, those funds which are legally available shall be used to
redeem the maximum possible number of Series D Preferred Shares pro rata among
the holders of the Series D Preferred Shares to be redeemed based upon the
aggregate Series D Liquidation Value of such Series D Preferred Shares held by
each such holder (plus all accrued and unpaid dividends thereon). At any time
thereafter when additional funds of the Corporation are legally available for
the redemption of Series D Preferred Shares, such funds shall immediately be
used to redeem the balance of the Series D Preferred Shares which the
Corporation has become obligated to redeem on the Scheduled Redemption Date but
which it has not redeemed.

         d. Notice of Redemption.  Except as otherwise provided herein, the
Corporation shall mail written notice of each redemption of any Series D
Preferred to each record holder thereof not more than 60 nor less than 30 days
prior to the date on which such redemption is to be made. To request redemption
of all or any portion of the outstanding Series D Preferred Shares, the holders
of a majority of the outstanding Series D Preferred Shares shall deliver written
notice to the Corporation, not more than 60 nor less than 30 days prior to the
date on which such redemption is to be made, specifying the amount or portion of
the outstanding Series D Preferred Shares which shall be subject to such
redemption. Upon receipt of such notice, the Corporation shall immediately mail
written notice of such redemption to each record holder of Series D Preferred.
The Corporation or the holders of a majority of the outstanding shares of Series
C Participating Preferred may deliver notice pursuant to this subsection prior
to the actual issuance of Series D Preferred upon conversion of Series C
Participating Preferred, which notice may be subject to the subsequent
conversion of the Series C Participating Preferred. The holders of a majority of
the outstanding Series D Preferred may waive the foregoing notice periods. In
case fewer than the total number of Series D Preferred Shares represented by any
certificate are redeemed, a new certificate representing the number of
unredeemed Series D Preferred Shares shall be issued to the holder thereof
without cost to such holder within five business days after surrender of the
certificate representing the redeemed Series D Preferred Shares.


                                      -34-
<PAGE>   35



         e. Determination of the Number of Each Holder's Series D Preferred
Shares to be Redeemed. Except as otherwise provided herein, the number of Series
D Preferred Shares to be redeemed from each holder thereof in redemptions
hereunder shall be the number of Series D Preferred Shares determined by
multiplying the total number of Series D Preferred Shares to be redeemed times a
fraction, the numerator of which shall be the total number of Series D Preferred
Shares then held by such holder and the denominator of which shall be the total
number of Series D Preferred Shares then outstanding.

         f. Dividends After Scheduled Redemption Date. No Series D Preferred
Share shall be entitled to any dividends accruing after the date on which the
Series D Liquidation Value of such Series D Preferred Share (plus all accrued
and unpaid dividends thereon) is paid to the holder of such Series D Preferred
Share. On such date, all rights of the holder of such Series D Preferred Share
shall cease, and such Series D Preferred Share shall no longer be deemed to be
issued and outstanding.

         g. Redeemed or Otherwise Acquired Series D Preferred Shares. Any
Series D Preferred Shares which are redeemed or otherwise acquired by the
Corporation shall be canceled and retired to authorized but unissued shares and
shall not be reissued, sold or transferred.

         Section 5. Voting Rights.

         Except as otherwise required by applicable law, each holder of Series D
Preferred Shares shall be entitled to vote, together with the holders of Series
A Preferred, Series B Preferred, Series C Participating Preferred, Common Stock,
and Class B Common as a single class, on all matters to be voted upon by the
shareholders of the Corporation, and in each such vote shall be entitled to that
number of votes (including fractions thereof) equal to the quotient determined
by dividing the aggregate Series D Liquidation Value of the shares so held by
the Orius Common Value Per Share (as defined in the Reorganization Agreement),
except as otherwise required by applicable law.

                                C. COMMON SHARES

         There shall be designated two classes of common stock of the
Corporation: Common Stock and Class B Common. Shares of common stock of the
Corporation outstanding on the date hereof and prior to the consummation of the
transactions contemplated in the Reorganization Agreement shall be designated
Common Stock. The number of shares of common stock shall be as set forth in this
Article Four. The rights, preferences and limitations of the Common Stock and
Class B Common are as set forth below.

         Section I. Voting Rights.

         Except as otherwise required by applicable law, the Common Stock, the
Class B Common and the Preferred Stock shall vote together as a single class on
all matters to be voted on


                                      -35-
<PAGE>   36


by the stockholders of the Corporation, with the holders of Common Stock
entitled to one vote per share and the holders of Class B Common entitled to ten
votes per share.

         Section 2. Dividends.

         As and when dividends are declared or paid with respect to shares of
Common Stock or Class B Common, whether in cash, property or securities of the
Corporation, the holders of Common Stock and the holders of Class B Common shall
be entitled to receive such dividends ratably on a per share basis, treating the
Common Stock and the Class B Common as a single class for such purposes. The
right of the holders of Common Stock and the right of the holders of Class B
Common to receive dividends are subject to the provisions of the Preferred
Stock; provided that if dividends are declared or paid in shares of Common or
Class B Common, the dividends payable in shares of Common Stock shall be payable
to holders of Common Stock and the dividends payable in shares of Class B Common
shall be payable to holders of Class B Common.

         Section 3. Liquidation.

         Subject to the provisions of the Preferred Stock, the holders of the
Common Stock and the holders of the Class B Common shall be entitled to
participate ratably on a per share basis in all distributions to the holders of
Common Stock or to the holders of Class B Common in any liquidation, dissolution
or winding up of the Corporation, basis, treating the Common Stock and the Class
B Common as a single class for such purposes.

         Section 4. Conversion of Class B Common.

         At such time as (i) all shares of Common Stock which, as contemplated
pursuant to the Reorganization Agreement, are subject to repurchase by the
Corporation pursuant to any call agreement entered into with the Corporation
dated on or prior to the date of the original issuance of the Series C
Participating Preferred, have been repurchased by the Corporation and are no
longer outstanding, and (ii) all outstanding shares of Series B Preferred
have been redeemed or purchased by the Corporation or any of its Subsidiaries
and are no longer outstanding, each outstanding share of Class B Common shall
automatically convert into one share of Common Stock.

                       ARTICLE I. MEETINGS OF STOCKHOLDERS

         SECTION 1. ANNUAL MEETING. The annual meeting of the stockholders of
the Corporation for the election of directors and the transaction of other
business shall be held on such date, at such time and in such place as shall be
determined by the board of directors. If any annual meeting is not held, by
oversight or otherwise, a special meeting shall be held as soon as practical,
and any business transacted or election held at that meeting shall be as valid
as if transacted or held at the annual meeting.

         SECTION 2. SPECIAL MEETINGS. Special meetings of the stockholders for
any purpose shall be held when called by the president or the board of
directors, or when demanded in writing by the holders of not less than ten
percent (unless a greater percentage not to exceed fifty percent is required by
the certificate of incorporation) of all the shares entitled to vote at the
meeting. Such demand must be delivered to the Corporation's secretary. A meeting
demanded by stockholders shall be called for a date not less than ten nor more
than sixty days after the request is made, unless the stockholders requesting
the meeting designate a later date. The secretary shall issue the call for the
meeting, unless the president, the board of directors, or stockholders
requesting the meeting designate another person to do so. The stockholders at a
special meeting may transact only business that is related to the purposes
stated in the notice of the special meeting.

         SECTION 3. PLACE. Meetings of stockholders may be held either within or
outside the State of Delaware.

         SECTION 4. NOTICE. A written notice of each meeting of stockholders,
stating the place, day, and time of the meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, shall be
delivered to each stockholder of record entitled to vote at the meeting, not
less than ten nor more than sixty days before the date set for the meeting,
either personally or by first-class mail, by or at the direction of the
president, the secretary, or the officer or other persons calling the meeting.
If mailed, the notice shall be considered delivered when it is deposited in the
United States mail, postage prepaid, addressed to the stockholder at his address
as it appears on the records of the Corporation.





<PAGE>   2





         SECTION 5. WAIVERS OF NOTICE. Whenever any notice is required to be
given to any stockholder of the Corporation under these bylaws, the certificate
of incorporation, or the Delaware General Corporation Law, a written waiver of
notice, signed anytime by the person entitled to notice shall be equivalent to
giving notice. Attendance by a stockholder entitled to vote at a meeting, in
person or by proxy, shall constitute a waiver of (a) notice of the meeting,
except when the stockholder attends a meeting solely for the purpose, expressed
at the beginning of the meeting, of objecting to the transaction of any business
because the meeting is not lawfully called or convened, and (b) an objection to
consideration of a particular matter at the meeting that is not within the
purpose of the meeting unless the stockholders object to considering the matter
when it is presented.

         SECTION 6. RECORD DATE. For the purpose of determining the stockholders
for any purpose, the board of directors may either require the stock transfer
books to be closed for up to seventy days or fix a record date, which shall be
not more than sixty nor less than ten days before the date on which the action
requiring the determination is to be taken. For the purpose of determining the
stockholders entitled to consent to corporate action in writing without a
meeting, however, a record date shall not precede the date upon which the
resolution fixing the record date is adopted or be more than ten days
thereafter. If the transfer books are not closed and no record date is set by
the board of directors, the record date shall be determined as follows: For
determining stockholders entitled to demand a special meeting, the record date
is the date the first such demand is delivered to the Corporation; For
determining stockholders entitled to a share dividend, the record date is the
date the board of directors authorizes the dividend; If no prior action is
required by the board of directors pursuant to the Delaware General Corporation
Law, the record date for determining stockholders entitled to take action
without a meeting is the date the first signed written consent is delivered to
the Corporation; If prior action is required by the board of directors pursuant
to the Delaware General Corporation Law, the record date for determining
stockholders entitled to take action without a meeting is at the close of
business on the day that the board of directors adopts a resolution taking such
prior action; and For determining stockholders entitled to notice of and to vote
at an annual or special stockholders meeting the record date is as of the close
of business on the day before the first notice is delivered to the stockholders.
When a determination of the stockholders entitled to vote at any meeting has
been made, that determination shall apply to any adjournment of the meeting,
unless the board of directors fixes a new record date. The board of directors
shall fix a new record date if the meeting is adjourned to a date more than 120
days after the date fixed for the original meeting.

         SECTION 7. STOCKHOLDER'S LIST FOR MEETING. A complete alphabetical list
of the names of the stockholders entitled to receive notice of and to vote at
the meeting shall be prepared by the secretary or other authorized agent having
charge of the stock transfer book. The list shall be arranged by voting group
and include each stockholder's address, and the number, series, and class of
shares held. The list must






                                        2

<PAGE>   3



be made available at least ten days before and throughout each meeting of
stockholders, or such shorter time as exists between the record date and the
meeting. The list must be made available at the Corporation's principal office,
registered agent's office, transfer agent's office or at a place identified in
the meeting notice in the city where the meeting will be held. Any stockholder,
his agent or attorney, upon written demand and at his own expense may inspect
the list during regular business hours. The list shall be available at the
meeting and any stockholder, his agent or attorney is entitled to inspect the
list at any time during the meeting or its adjournment.

         If the requirements of this section have not been substantially
complied with, the meeting, on the demand of any stockholder in person or by
proxy, shall be adjourned until the requirements of this section are met. If no
demand for adjournment is made, failure to comply with the requirements of this
section does not affect the validity of any action taken at the meeting.

         SECTION 8. STOCKHOLDER QUORUM AND VOTING. A majority of the shares
entitled to vote, represented in person or by proxy, constitutes a quorum at a
meeting of stockholders. If a quorum is present, the affirmative vote of a
majority of the shares entitled to vote on the matter is the act of the
stockholders unless otherwise provided by law. A stockholder may vote either in
person or by proxy executed in writing by the stockholder or his duly authorized
attorney-in-fact. After a quorum has been established at a stockholders'
meeting, a withdrawal of stockholders that reduces the number of stockholders
entitled to vote at the meeting below the number required for a quorum does not
affect the validity of an adjournment of the meeting or an action taken at the
meeting prior to the stockholders' withdrawal.

         Authorized but unissued shares including those redeemed or otherwise
reacquired by the corporation, and shares of stock of this Corporation owned by
another corporation the majority of the voting stock of which is owned or
controlled by this Corporation, directly or indirectly, at any meeting shall not
be counted in determining the total number of outstanding shares at any time.
The chairman of the board, the president, any vice president, the secretary, and
the treasurer of a corporate stockholder are presumed to possess, in that order,
authority to vote shares standing in the name of a corporate stockholder,
absent a bylaw or other instrument of the corporate stockholder designating some
other officer, agent, or proxy to vote the shares. Shares held by an
administrator, executor, guardian, or conservator may be voted by him without a
transfer of the shares into his name. A trustee may vote shares standing in his
name, but no trustee may vote shares that are not transferred into his name. If
he is authorized to do so by an appropriate order of the court by which he was
appointed, a receiver may vote shares standing in his name or held by or under
his control, without transferring the shares into his name. A stockholder whose
shares are pledged may vote the shares until the shares have been transferred
into the name of the pledgee, and thereafter the pledgee or his nominee shall be

                              ARTICLE II. DIRECTORS

and its corporate powers exercised by the board of directors.

         SECTION 2. NUMBER. The Corporation shall have at least one (1) director
at all times. The number of directors may be increased or diminished from time
to time by action of the board of directors or stockholders, but no decrease
shall have the effect of shortening the term of any incumbent director, unless
the stockholders remove the director.

         SECTION 3. QUALIFICATION. Each member of the board of directors must be
a natural person who is eighteen years of age or older. A director need not be a
resident of Delaware or a stockholder of the Corporation.

         SECTION 4. ELECTION AND TERM. The persons named in the certificate of
incorporation as members of the initial board of directors shall hold office
until the first annual meeting of stockholders and until their successors have
been elected and qualified or until their earlier resignation, removal from
office, or death. At the first annual meeting of stockholders and at each annual
meeting thereafter the stockholders shall elect directors to hold office until
the next succeeding annual meeting. Each director shall hold office for the term
for which he is elected and until his successor is elected and qualifies or
until his earlier resignation, removal from office, or death.

         SECTION 5. COMPENSATION. The board of directors has authority to fix
the compensation of the directors, as directors and as officers.

         SECTION 6. DUTIES OF DIRECTORS. A director shall perform his duties as
a director, including his duties as a member of any committee of the board upon
which he serves, in good faith, in a manner he reasonably believes to be in the
best interests of the Corporation.

         SECTION 7. PRESUMPTION OF ASSENT. A director of the Corporation who is
present at a meeting of the board of directors or a committee of the board of
directors when corporate action is taken is presumed to have assented to the
action unless he votes against it or expressly abstains from voting on the
action taken, or, he objects at the beginning of the meeting to the holding of
the meeting or transacting specific business at the meeting.

         SECTION 8. VACANCIES. Unless filled by the stockholders, any vacancy
occurring in the board OF directors, including any vacancy created because of an
increase in the number of directors, may be filled by the affirmative vote of a
majority of the remaining directors, even if the number of remaining directors
does not constitute a quorum of the board of directors. A director elected to
fill a vacancy shall hold office only until the next election of directors by
the stockholders.

         SECTION 9. REMOVAL OR RESIGNATION OF DIRECTORS. At a meeting of
stockholders called for that purpose, the stockholders, by a vote of the
holders of a majority of the shares entitled to vote at an election of
directors, may remove any director, or the entire board of directors, with or
without cause, and fill any vacancy or vacancies created by the removal.

         A director may resign at any time by delivering written notice to the
board of directors or its chairman or the corporation. A resignation is
effective when the notice is delivered unless the notice specifies later
effective date. If a resignation is made effective at a later date, the board of
directors may fill the pending vacancy before the effective date if the board of
directors provided that the successor does not take office until the effective
date.

         SECTION 10. QUORUM AND VOTING. A majority of the board of directors
constitutes a quorum for the transaction of business. The act of the majority of
the directors at a meeting at which a quorum is present is the act of the board
of directors.

         SECTION 11. PLACE OF MEETINGS. Regular and special meetings by the
board of directors may be held within or outside the State of Delaware.

         SECTION 12. REGULAR MEETINGS. A regular meeting of the board of
directors shall be held without notice, other than this bylaw, immediately after
and at the same place as the annual meeting of stockholders. The board of
directors may provide, by resolution, the time and place for the holding of
additional regular meetings without notice other than the resolution.

         SECTION 13. SPECIAL MEETINGS. Special meetings of the board of
directors may be called by or at the request of the president or any directors.

         SECTION 14. NOTICE OF MEETINGS. Written notice of the time and place of
special meetings of the board of directors shall be given to each director by
either personal delivery or by first class United States mail, telegram, or
cablegram at least two days before the meeting. Notice of a meeting of the board
of directors need not be given to any director who signs a waiver of notice
either before or after the meeting. Attendance of a director at a meeting
constitutes a waiver of notice of the meeting and all objections to the time and
place of the meeting, or the manner in which it has been called or convened,
except when the director states, at the beginning of the meeting, or promptly
upon arrival at the meeting, any objection to the transaction of business
because the meeting is not lawfully called or convened. Neither the business to
be transacted at, nor the purpose of, any regular or special meeting of the
board of directors need be specified in the notice or waiver of notice of the
meeting.

         A majority of the directors present, whether or not a quorum exists,
may adjourn any meeting of the board of directors to another time and place.
Notice of any adjourned meeting shall be given to the directors who were not
present at the time of





                                        5
<PAGE>   6


the adjournment and, unless the time and place of the adjourned meeting are
announced at the time of the adjournment, to the other directors.


                              ARTICLE III. OFFICERS

         SECTION 1. OFFICERS. The officers of the Corporation shall consist of a
president, a secretary, and a treasurer, and may include one or more vice
presidents, one or more assistant secretaries, and one or more assistant
treasurers. The officers shall be elected initially by the board of directors at
the organizational meeting of board of directors and thereafter at the first
meeting of the board following the annual meeting of the stockholders in each
year. The board from time to time may elect or appoint other officers, assistant
officers, and agents, who shall have the authority and perform the duties
prescribed by the board. An elected or duly appointed officer may, in turn,
appoint one or more officers or assistant officers, unless the board of
directors disapproves or rejects the appointment. All officers shall hold office
until their successors have been appointed and have qualified or until their
earlier resignation, removal from office, or death. One person may
simultaneously hold any two or more offices. The failure to elect a president,
secretary, or treasurer shall not affect the existence of the Corporation.

         SECTION 2. PRESIDENT. The president, subject to the directions of the
board of directors, is responsible for the general and active management of the
business and affairs of the Corporation, has the power to sign certificates of
stock, bonds, deeds, and contracts for the Corporation, and shall preside at all
meetings of the stockholders.

         SECTION 3. VICE PRESIDENTS. Each vice president has the power to sign
bonds, deeds, and contracts for the Corporation and shall have the other powers
and perform the other duties prescribed by the board of directors or the
president. Unless the board otherwise provides, if the president is absent or
unable to act, the vice president who has served in that capacity for the
longest time and who is present and able to act shall perform all the duties and
may exercise any of the powers of the president. Any vice president may sign,
with the secretary or assistant secretary, certificates for stock of the
Corporation.

         SECTION 4. SECRETARY. The secretary shall have the power to sign
contracts and other instruments for the Corporation and shall (a) keep the
minutes of the proceedings of the stockholders and the board of directors in one
or more books provided for that purpose, (b) see that all notices are duly given
in accordance with the provisions of these bylaws or as required by law, (c)
maintain custody of the corporate records and the corporate seal, attest the
signatures of officers who execute documents on behalf of the Corporation,
authenticate records of the Corporation, and assure that the seal is affixed to
all documents of which execution on behalf of the Corporation under its seal is
duly authorized, (d) keep a register of the post office address of each
stockholder that shall be furnished to the secretary by the stockholder, (e)
sign with the





                                        6
<PAGE>   7


president, or a vice president, certificates for shares of stock of the
Corporation, the issuance of which have been authorized by resolution of the
board of directors, (f) have general charge of the stock transfer books of the
Corporation, and (g) in general perform all duties incident to the office of
secretary and other duties as from time to time may be prescribed by the
president or the board of directors.

         SECTION 5. TREASURER. The treasurer shall (a) have charge and custody
of and be responsible for all funds and securities of the Corporation, (b)
receive and give receipts for monies due and payable to the Corporation from any
source whatsoever, and deposit monies in the name of the Corporation in the
banks, trust companies, or other depositaries as shall be selected by the board
of directors, and (c) in general perform all the duties incident to the office
of treasurer and other duties as from time to time may be assigned to him by the
president or the board of directors. If required by the board of directors, the
treasurer shall give a bond for the faithful discharge of his duties in the sum
and with the surety or sureties that the board of directors determines.

         SECTION 6. REMOVAL OF OFFICERS. An officer or agent elected or
appointed by the board of directors or appointed by another officer may be
removed by the board whenever in its judgment the removal of the officer or
agent will serve the best interests of the Corporation. Any officer or assistant
officer, if appointed by another officer, may likewise be removed by such
officer. Removal shall be without prejudice to any contract rights of the person
removed. The appointment of any person as an officer, agent, or employee of
the Corporation does not create any contract rights. The board of directors may
fill a vacancy, however occurring, in any office.

         An officer may resign at any time by delivering notice to the
corporation. A resignation is effective when the notice is delivered unless the
notice specifies a later effective date. If a resignation is made effective at a
later date, its board of directors may fill the pending vacancy before the
effective date if the board of directors provides that the successor does not
take office until the effective date. An officer's resignation does not affect
the officer's contract rights, if any, with the corporation.

         SECTION 7. SALARIES. The board of directors from time to time shall fix
the salaries of the officers, and no officer shall be prevented from receiving
his salary merely because he is also a director of the Corporation.


                           ARTICLE IV. INDEMNIFICATION

         Any person, his heirs, or personal representative, made, or threatened
to be made, a party to any threatened, pending, or completed action or
proceeding, whether civil, criminal, administrative, or investigative, because
he is or was a director, officer, employee, or agent of this Corporation or
serves or served any other corporation or other enterprise in any capacity at
the request of this Corporation, shall be




                                        7
<PAGE>   8




indemnified by this Corporation, and this Corporation may advance his related
expenses to the full extent permitted by Delaware law. In discharging his duty,
any director, officer, employee, or agent, when acting in good faith, may rely
upon information, opinions, reports, or statements, including financial
statements and other financial data, in each case prepared or presented by (1)
one or more officers or employees of the Corporation whom the director, officer,
employee, or agent reasonably believes to be reliable and competent in the
matters presented, (2) counsel, public accountants, or other persons as to
matters that the director, officer, employee, or agent believes to be within
that person's professional or expert competence, or (3) in the case of a
director, a committee of the board of directors upon which he does not serve,
duly designated according to law, as to matters within its designated authority,
if the director reasonably believes that the committee is competent. The
foregoing right of indemnification or reimbursement shall not be exclusive of
other rights to which the person, his heirs, or personal representatives may be
entitled. The Corporation may, upon the affirmative vote of a majority of its
board of directors, purchase insurance for the purpose of indemnifying these
persons. The insurance may be for the benefit of all directors, officers, or
employees.


                          ARTICLE V. STOCK CERTIFICATES

         SECTION 1. ISSUANCE. Shares may but need not be represented by
certificates. The board of directors may authorize the issuance of some or all
of the shares of the Corporation of any or all of its classes or series without
certificates. If certificates are to be issued, the share must first be fully
paid.

         SECTION 2. FORM. Certificates evidencing shares in this Corporation
shall be signed by the president or a vice president and the secretary,
assistant secretary or any other officer authorized by the board of directors,
and may be sealed with the seal of this Corporation or a facsimile of the seal.
Unless the Corporation's stock is registered pursuant to every applicable
securities law, each certificate shall bear an appropriate legend restricting
the transfer of the shares evidenced by that certificate.

         SECTION 3. LOST, STOLEN, OR DESTROYED CERTIFICATES. The Corporation may
issue a new certificate in the place of any certificate previously issued if the
stockholder of record (a) makes proof in affidavit form that the certificate has
been lost, destroyed, or wrongfully taken, (b) requests the issue of a new
certificate before the Corporation has notice that the certificate has been
acquired by the purchaser for value in good faith and without notice of any
adverse claim, (c) if requested by the Corporation, gives bond in the form that
the Corporation directs, to indemnify the Corporation, the transfer agent, and
the registrar against any claim that may be made concerning the alleged loss,
destruction, or theft of a certificate, and (d) satisfies any other reasonable
requirements imposed by the Corporation.

         SECTION 4. RESTRICTIVE LEGEND. Every certificate evidencing shares that
are restricted as to sale, disposition, or other transfer shall bear a legend
summarizing the restriction or stating that the Corporation will furnish to any

restriction.

         The board of directors from time to time may declare, and the
Corporation may pay, dividends on its outstanding shares in the manner and upon
the terms and conditions provided by law.


                                ARTICLE VII. SEAL

         The corporate seal shall have the name of the Corporation and the word
"seal" inscribed on it, and may be a facsimile, engraved, printed, or an
impression seal.


                             ARTICLE VIII. AMENDMENT

         These bylaws may be repealed or amended, and additional bylaws may be
adopted, by either a vote of a majority of the full board of directors or by
vote of the holders of a majority of the issued and outstanding shares entitled
to vote, but the board of directors may not amend or repeal any bylaw adopted by
the stockholders if the stockholders specifically provide that the bylaw is not
subject to amendment or repeal by the directors. In order to be effective, any
amendment approved hereby must be in writing and attached to these Bylaws.

                              AMENDED AND RESTATED

                      LIMITED LIABILITY COMPANY AGREEMENT

                                       OF

                               NATG HOLDINGS, LLC

                      A DELAWARE LIMITED LIABILITY COMPANY

SECTION 1.01    INITIAL DATE; INITIAL PARTIES

This Amended and Restated Agreement ("Agreement") is first made as of February
18, 1999, and agreed to by NATG Holdings, LLC (the "Company") and Orius Corp., a
Delaware corporation (the "Initial Member"), the sole Member of the Company on
such date.


SECTION 1.02    SUBSEQUENT PARTIES; ASSENT AS A PRECONDITION TO BECOMING
                A MEMBER OR TO OBTAINING RIGHTS TO BECOME A MEMBER

(a)      No Person may become a Member of the Company without first assenting
         to and signing this Agreement. Any act by the Company to offer or
         provide Member status, or reflect that status in the Company's
         Required Records, automatically includes the condition that the Person
         becoming a Member first assent to and sign this Agreement.

(b)      If (i) the Company offers, makes, or signs a Contribution Agreement,
         Warrant (and a related Warrant Agreement, if any), Option or any other
         agreement that permits or requires a Person to make a Capital
         Contribution and become a Member, and (ii) the other party to the
         Contribution Agreement, Warrant (and related Warrant Agreement, if
         any), Option or other agreement is not already a Member and has not
         already assented to and signed this Agreement, then the Company's
         action automatically includes the condition that the other party
         assent to and sign this Agreement before that Person actually makes a
         Capital Contribution or becomes a Member.

(c)      The Company is obligated not to accept a Capital Contribution from, or
         accord Member status to, any Person who has not first assented to and
         signed this Agreement. The Company's acceptance of a Capital
         Contribution from a Person


<PAGE>   2


         who has not signed this Agreement does not waive that Person's
         obligation to sign this Agreement.

(d)      No Transfer of a Membership Unit is effective unless the transferee
         has assented to and signed this Agreement; provided, however, that for
         purposes of this Section 1.02(d) "Transfer" shall not include a
         mortgage or the grant of a security interest and no mortgagee or
         holder of a security interest shall be required to assent to or sign
         this Agreement. Any such mortgagee or holder of such a security
         interest shall be permitted to record such interest.


SECTION 1.03    AUTHORIZATION OF THIS AGREEMENT

This Agreement is made under the Delaware Limited Liability Company Act (the
"LLC Act"), as the same may be amended from time to time.


SECTION 1.04    PERPETUAL LIFE

The Company will have perpetual life unless the Company is dissolved as
hereinafter provided, and will not terminate or be dissolved upon the death,
retirement, resignation, expulsion, Bankruptcy or dissolution of a Member or
the occurrence of any other event which terminates the continued membership of
a Member in the Company.

certificate of incorporation, any action required to be taken at any annual or
special meeting of stockholders of the corporation, or any action which may be

recorded when so delivered. No written consent shall be effective to take the
corporate action referred to therein unless, within sixty days of the earliest
dated consent delivered to the corporation as required by this section, written
consents signed by the holders of a sufficient number of shares to take such
corporate action are so recorded. Prompt notice of the taking of the corporate
action without a meeting by less than unanimous written consent shall be given
to those stockholders who have not consented in writing. Any action taken
pursuant to such written consent or consents of the stockholders shall have the

majority of the shares then entitled to vote at an election of directors.
Whenever the holders of any class or series are entitled to elect one or more
directors by the provisions of the corporation's certificate of incorporation,
the provisions of this section shall apply, in respect to the removal without
cause of a director or directors so elected, to the vote of the holders of the
outstanding shares of that class or series and not to the vote of the
outstanding shares as a whole. Any director may resign at any time upon written
notice to the corporation.

         Section 4. Vacancies. Vacancies and newly created directorships
resulting from any increase in the authorized number of directors may be filled

resignation or removal as herein provided.

         Section 5. Annual Meetings. The annual meeting of each newly elected
board of directors shall be held without other notice than this by-law
immediately after, and at the same place as, the annual meeting of stockholders.

         Section 6. Other Meetings and Notice. Regular meetings, other than the
annual meeting, of the board of directors may be held without notice at such
time and at such place as shall from time to time be determined by resolution of

request of the president or any director on at least 24 hours notice to each
director, either personally, by telephone, by mail, or by telegraph.

         Section 7. Quorum, Required Vote and Adjournment. A majority of the
total number of directors shall constitute a quorum for the transaction of
business. The vote of a majority of directors present at a meeting at which a
quorum is present shall be the act of the board of directors. If a quorum shall
not be present at any meeting of the board of directors, the directors present
thereat may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.

         Section 8. Committees. The board of directors may, by resolution passed
by a majority of the whole board, designate one or more committees, each
committee to consist of one or more of the




                                      -4-
<PAGE>   5



directors of the corporation, which to the extent provided in such resolution or
these by-laws shall have and may exercise the powers of the board of directors
in the management and affairs of the corporation except as otherwise limited by
law. The board of directors may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee. Such committee or committees shall have such name
or names as may be determined from time to time by resolution adopted by the
board of directors. Each committee shall keep regular minutes of its meetings
and report the same to the board of directors when required.

         Section 9. Committee Rules. Each committee of the board of directors
may fix its own rules of procedure and shall hold its meetings as provided by
such rules, except as may otherwise be provided by a resolution of the board of
directors designating such committee. In the event that a member and that
member's alternate, if alternates are designated by the board of directors as
provided in Section 8 of this Article III, of such committee is or are absent or

         Section 10. Communications Equipment. Members of the board of directors
or any committee thereof may participate in and act at any meeting of such board
or committee through the use of a conference telephone or other communications

constitute presence in person at the meeting.

         Section 11. Waiver of Notice and Presumption of Assent. Any member of
the board of directors or any committee thereof who is present at a meeting
shall be conclusively presumed to have waived notice of such meeting except when
such member attends for the express purpose of objecting at the beginning of the

the corporation, in case of death, resignation, retirement, or removal from
office, of all books, papers, vouchers, money, and other property of whatever
kind in the possession or under the control of the treasurer belonging to the
corporation. The assistant treasurer, or if there shall be more than one, the
assistant treasurers in the order determined by the board of directors, shall in
the absence or disability of the treasurer, perform the duties and exercise the
powers of the treasurer. The assistant treasurers shall perform such other

         Section 14. Absence or Disability of Officers. In the case of the
absence or disability of any officer of the corporation and of any person hereby

                                    ARTICLE V

                INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS

         Section 1. Nature of Indemnity. Each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer,
of the corporation or is or was serving at the request of the corporation as a
director, officer, employee, fiduciary, or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, shall be indemnified and
held harmless by the corporation to the fullest extent which it is empowered to
do so by the General Corporation Law of the State of Delaware, as the same
exists or may hereafter be amended against all expense, liability and loss
(including attorneys' fees actually and reasonably incurred by such person in
connection with such proceeding) and such indemnification shall inure to the
benefit of his or her heirs, executors and administrators; provided, however,
that, except as provided in Section 2 hereof, 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 in this
Article V shall be a contract right and, subject to Sections 2 and 5 hereof,
shall include the right to be paid by the corporation the expenses incurred in
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
foregoing indemnification of directors and officers.

         Section 2. Procedure for Indemnification of Directors and Officers. Any
indemnification of a director or officer of the corporation under Section 1 of
this Article V or advance of expenses under Section 5 of this Article V shall be
made promptly, and in any event within 30 days, upon the written request of the
director or officer. If a determination by the corporation that the director or
officer is entitled to indemnification pursuant to this Article V is required,
and the corporation fails to respond within sixty days to a written request for
indemnity, the corporation shall be deemed to have approved the request. If the
corporation denies a written request for indemnification or advancing of
expenses, in whole or in part, or if payment in full pursuant to such request is
not made within 30 days, the right to indemnification or advances as granted by
this Article V shall be enforceable by the director or officer in any court of
competent jurisdiction. Such person's costs and expenses incurred in connection
with successfully establishing his or her right to indemnification, in whole or
in part, in any such action shall also be indemnified by the corporation. It
shall be a





                                      -8-
<PAGE>   9


defense to any such action (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking, if any, has been tendered to the
corporation) that the claimant has not met the standards of conduct which make
it permissible under the General Corporation Law of the State of Delaware for
the corporation to indemnify the claimant for the amount claimed, but the burden
of such defense shall be on the corporation. Neither the failure of the
corporation (including its board of directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
General Corporation Law of the State of Delaware, nor an actual determination by
the corporation (including its board of directors, independent legal counsel, or
its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

         Section 3. Article Not Exclusive. The rights to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Article V shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute,
provision of the certificate of incorporation, by-law, agreement, vote of
stockholders or disinterested directors or otherwise.

         Section 4. Insurance. The corporation may purchase and maintain
insurance on its own behalf and on behalf of any person who is or was a
director, officer, employee, fiduciary, or agent of the corporation or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him or her and incurred by him
or her in any such capacity, whether or not the corporation would have the power
to indemnify such person against such liability under this Article V.

         Section 5. Expenses. Expenses incurred by any person described in
Section 1 of this Article V in defending a proceeding shall be paid by the
corporation in advance of such proceeding's final disposition unless otherwise
determined by the board of directors in the specific case upon receipt of an
undertaking by or on behalf of the director or officer to repay such amount if
it shall ultimately be determined that he or she is not entitled to be
indemnified by the corporation. Such expenses incurred by other employees and
agents may be so paid upon such terms and conditions, if any, as the board of
directors deems appropriate.

         Section 6. Employees and Agents. Persons who are not covered by the
foregoing provisions of this Article V and who are or were employees or agents
of the corporation, or who are or were serving at the request of the corporation
as employees or agents of another corporation, partnership, joint venture, trust
or other enterprise, may be indemnified to the extent authorized at any time or
from time to time by the board of directors.

         Section 7. Contract Rights. The provisions of this Article V shall be
deemed to be a contract right between the corporation and each director or
officer who serves in any such capacity at any time while this Article V and the
relevant provisions of the General Corporation Law of the State of Delaware or
other applicable law are in effect, and any repeal or modification of this
Article V or any such law shall not affect any rights or obligations then
existing with respect to any state of facts or proceeding then existing.

         Section 8. Merger or Consolidation. For purposes of this Article V,
references to "the corporation" shall include, in addition to the resulting
corporation, any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was
a director, officer, employee or agent of such constituent corporation, or is
or was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under this Article V
with respect to the resulting or surviving corporation as he or she would have
with respect to such constituent corporation if its separate existence had
continued.


                                   ARTICLE VI

                              CERTIFICATES OF STOCK

         Section 1. Form. Every holder of stock in the corporation shall be
entitled to have a certificate, signed by, or in the name of the corporation by
the president or a vice-president and the secretary or an assistant secretary of
the corporation, certifying the number of shares owned by such holder in the
corporation. If such a certificate is countersigned (1) by a transfer agent or
an assistant transfer agent other than the corporation or its employee or (2) by
a registrar, other than the corporation or its employee, the signature of any
such president, vice-president, secretary, or assistant secretary may be
facsimiles. In case any officer or officers who have signed, or whose facsimile
signature or signatures have been used on, any such certificate or certificates
shall cease to be such officer or officers of the corporation whether because of
death, resignation or otherwise before such certificate or certificates have
been delivered by the corporation, such certificate or certificates may
nevertheless be issued and delivered as though the person or persons who signed
such certificate or certificates or whose facsimile signature or signatures have
been used thereon had not ceased to be such officer or officers of the
corporation. All certificates for shares shall be consecutively numbered or
otherwise identified. The name of the person to whom the shares represented
thereby are issued, with the number of shares and date of issue, shall be
entered on the books of the corporation. Shares of stock of the corporation
shall only be transferred on the books of the corporation by the holder of
record thereof or by such holder's attorney duly authorized in writing, upon
surrender to the corporation of the certificate or certificates for such shares
endorsed by the appropriate person or persons, with such evidence of the
authenticity of such endorsement, transfer, authorization, and other matters
as the corporation may reasonably require, and





                                      -10-

<PAGE>   11



accompanied by all necessary stock transfer stamps. In that event, it shall be
the duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate or certificates, and record the transaction
on its books. The board of directors may appoint a bank or trust company
organized under the laws of the United States or any state thereof to act as its
transfer agent or registrar, or both in connection with the transfer of any
class or series of securities of the corporation.

         Section 2. Lost Certificates. The board of directors may direct a new
certificate or certificates to be issued in place of any certificate or
certificates previously issued by the corporation alleged to have been lost,
stolen, or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen, or destroyed. When
authorizing such issue of a new certificate or certificates, the board of
directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen, or destroyed certificate or
certificates, or his or her legal representative, to give the corporation a bond
sufficient to indemnify the corporation against any claim that may be made
against the corporation on account of the loss, theft or destruction of any such
certificate or the issuance of such new certificate.

         Section 3. Fixing a Record Date for Stockholder Meetings. In order that
the corporation may determine the stockholders entitled to notice of or to vote
at any meeting of stockholders or any adjournment thereof, the board of
directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the board of
directors, and which record date shall not be more than sixty nor less than ten
days before the date of such meeting. If no record date is fixed by the board of
directors, the record date for determining stockholders entitled to notice of or
to vote at a meeting of stockholders shall be the close of business on the next
day preceding the day on which notice is given, or if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held. A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the board of directors may fix a new record date for the
adjourned meeting.

         Section 4. Fixing a Record Date for Action by Written Consent. In order
that the corporation may determine the stockholders entitled to consent to
corporate action in writing without a meeting, the board of directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the board of directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the board of directors. If no
record date has been fixed by the board of directors, the record date for
determining stockholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the board of directors is required by
statute, shall be the first date on which a signed written consent setting forth
the action taken or proposed to be taken is delivered to the corporation by
delivery to its registered office in the State of Delaware, its principal place
of business, or an officer or agent of the corporation having custody of the
book in which proceedings of meetings of stockholders are recorded. Delivery
made to the corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested. If no record date has been






                                      -11-

<PAGE>   12




fixed by the board of directors and prior action by the board of directors is
required by statute, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting shall be at the close
of business on the day on which the board of directors adopts the resolution
taking such prior action.

         Section 5. Fixing a Record Date for Other Purposes. In order that the
corporation may determine the stockholders entitled to receive payment of any
dividend or other distribution or allotment or any rights or the stockholders
entitled to exercise any rights in respect of any change, conversion or exchange
of stock, or for the purposes of any other lawful action, the board of directors
may fix a record date, which record date shall not precede the date upon which
the resolution fixing the record date is adopted, and which record date shall be
not more than sixty days prior to such action. If no record date is fixed, the
record date for determining stockholders for any such purpose shall be at the
close of business on the day on which the board of directors adopts the
resolution relating thereto.

         Section 6. Registered Stockholders. Prior to the surrender to the
corporation of the certificate or certificates for a share or shares of stock
with a request to record the transfer of such share or shares, the corporation
may treat the registered owner as the person entitled to receive dividends, to
vote, to receive notifications, and otherwise to exercise all the rights and
powers of an owner.

         Section 7. Subscriptions for Stock: Unless otherwise provided for in
the subscription agreement, subscriptions for shares shall be paid in full at
such time, or in such installments and at such times, as shall be determined by
the board of directors. Any call made by the board of directors for payment on
subscriptions shall be uniform as to all shares of the same class or as to all
shares of the same series. In case of default in the payment of any installment
or call when such payment is due, the corporation may proceed to collect the
amount due in the same manner as any debt due the corporation.


                                   ARTICLE VII

                               GENERAL PROVISIONS

         Section 1. Dividends. Dividends upon the capital stock of the
corporation, subject to the provisions of the certificate of incorporation, if
any, may be declared by the board of directors at any regular or special
meeting, pursuant to law. Dividends may be paid in cash, in property, or in
shares of the capital stock, subject to the provisions of the certificate of
incorporation. Before payment of any dividend, there may be set aside out of any
funds of the corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or any other purpose
and the directors may modify or abolish any such reserve in the manner in which
it was created.

         Section 2. Checks, Drafts or Orders. All checks, drafts, or other
orders for the payment of money by or to the corporation and all notes and other
evidences of indebtedness issued in the name of the corporation shall be signed
by such officer or officers, agent or agents of the corporation, and in such
manner, as shall be determined by resolution of the board of directors or a duly
authorized committee thereof.

         Section 3. Contracts. The board of directors may authorize any officer
or officers, or any agent or agents, of the corporation to enter into any
contract or to execute and deliver any instrument in the name of and on behalf
of the corporation, and such authority may be general or confined to specific
instances.

         Section 4. Loans. No loans shall be made by the corporation to its
officers or directors, and no loans shall be made by the corporation secured by
its shares. No loans shall be made or contracted on behalf of the corporation
and no evidences of indebtedness shall be issued in its name unless authorized
by resolution of the board of directors. Such authority may be general or
confined to specific instances.

         Section 5. Fiscal Year. The fiscal year of the corporation shall be
fixed by resolution of the board of directors.

         Section 6. Corporate Seal. The board of directors shall provide a
corporate seal which shall be in the form of a circle and shall have inscribed
thereon the name of the corporation and the words "Corporate Seal, Delaware".
The seal may be used by causing it or a facsimile thereof to be impressed or
affixed or reproduced or otherwise.

         Section 7. Voting Securities Owned By Corporation. Voting securities in
any other corporation held by the corporation shall be voted by the president,
unless the board of directors specifically confers authority to vote with
respect thereto, which authority may be general or confined to specific
instances, upon some other person or officer. Any person authorized to vote
securities shall have the power to appoint proxies, with general power of
substitution.

         Section 8. Inspection of Books and Records. Any stockholder of record,
in person or by attorney or other agent, shall, upon written demand under oath
stating the purpose thereof, have the right during the usual hours for business
to inspect for any proper purpose the corporation's stock ledger, a list of its
stockholders, and its other books and records, and to make copies or extracts
therefrom. A proper purpose shall mean any purpose reasonably related to such
person's interest as a stockholder. In every instance where an attorney or other
agent shall be the person who seeks the right to inspection, the demand under
oath shall be accompanied by a power of attorney or such other writing which
authorizes the attorney or other agent to so act on behalf of the stockholder.
The demand under oath shall be directed to the corporation at its registered
office in the State of Delaware or at its principal place of business.

         Section 9. Section Headings. Section headings in these by-laws are for
convenience of reference only and shall not be given any substantive effect in
limiting or otherwise construing any provision herein.

         Section 10. Inconsistent Provisions. In the event that any provision of
these by-laws is or becomes inconsistent with any provision of the certificate
of incorporation, the General Corporation Law of the State of Delaware or any
other applicable law, the provision of these by-laws shall not be given any
effect to the extent of such inconsistency but shall otherwise be given full

<PAGE>   2
A Convertible Preferred Stock." The rights, privileges, vote, liquidation
preference, convertibility, dividend and redemption provisions for the Series A
Convertible Preferred Stock are set forth on Exhibit A attached hereto.

         B.  Provisions Relating to the Common Stock. The Common Stock shall be
subject to the express terms of the Preferred Stock and any class or series
thereof. The powers, preferences and rights of the Class A Common Stock, the
Class B Common Stock and the Common Stock, and the qualifications, limitations
and restrictions thereof, shall in all respects be identical, except as
otherwise required by law or as expressly provided in the agreement among the
stockholders of the Corporation in the agreement among the stockholders of the
Corporation dated as of March 31, 1998.

             1.  Voting Rights. Except as otherwise required by law or as
may be provided by the resolutions of the Board authorizing the issuance of any
class or series of the Preferred Stock, as hereinafter provided, all rights to
vote and all voting power shall be vested exclusively in the holders of the
Common Stock. The holders of shares of Class A Common Stock and Class B Common
Stock shall have the following voting rights:

                 a. The holders of Class A Common Stock shall be entitled to one
             vote for each share of Class A Common Stock held, provided,
             however, that in no event shall the Class A Common Stock, in the
             aggregate, be entitled to more than 20% of the total number of
             votes allocable to all issued and outstanding voting shares of
             capital stock of the Corporation. In the event that the total
             number of issued and outstanding shares of Class A Common Stock
             shall be greater than 20% of all votes entitled to be cast by
             holders of issued and outstanding shares of capital stock of the
             Corporation, each share of Class A Common Stock shall be entitled
             to that number of votes equal to a fraction, the numerator of which
             shall be 20% of the total number of votes entitled to be cast by
             holders of shares of capital stock of the Corporation and the
             denominator of which shall be the total number of shares of Class A
             Common Stock then issued and outstanding.

                 b.  The holders of Class B Common Stock shall be entitled to
             one vote for each share of Class B Common Stock held.

             2.  Dividends. Subject to the rights of the holders of the
Preferred Stock, the holders of the Common Stock shall be entitled to receive
when, as and if declared by the Board, out of funds legally available therefor,
dividends and other distributions payable in cash, property, stock (including
shares of any class or series of the Corporation, whether or not shares of such
class or series are already outstanding) or otherwise.

3. Conversion.

     a. Mandatory Conversion. Immediately prior to the earliest to occur of (i)
the acquisition by the Corporation (whether by acquisition of all of the
outstanding shares of such operating company or substantially all of the assets
of such operating company ) of the third operating company acquired by the
Corporation after the date hereof; (ii) the effective date of the Corporation's
initial public offering of Common Stock; or (iii) the conversion of the
Corporation's Series A Convertible Preferred Stock into Common Stock (the
"Conversion Date"); then each share of Class B Common Stock then issued and
outstanding shall thereupon be converted automatically as of such Conversion
Date into one fully paid and nonassessable share of Common Stock (without class
designation), as may be proportionately adjusted by the Board of Directors for
the dilutive effects of additional issuances of Common Stock, and will have one
vote per share (a "Mandatory Conversion"); and each share of Class A common
Stock shall be converted into one fully paid and nonassessable share of Common
Stock (without class designation), as may be proportionately adjusted by the
Board of Directors for the dilutive effects of additional issuances of Common
Stock; provided however, that upon the Mandatory Conversion, the shares of
Common Stock issuable upon the conversion of the Class A Common Stock will
represent no more than 20% of the outstanding voting shares of the Corporation.
Notice of such Mandatory Conversion shall be given by the Corporation as soon as
practicable, but no later than the next meeting of shareholders of the
Corporation, by means of written notice to all holders of Class A and Class B
Common Stock, and the Secretary of the Corporation shall be instrued to and
shall promptly request that each holder of Class A and Class B Common Stock
promptly deliver, and each such holder shall promptly deliver, the certificate
or certificates representing each share of such Class A and Class B Common Stock
to the Corporation or the Transfer Agent. If so required by the Corporation or
the Transfer Agent, any certificate for shares surrendered for conversion
shall be accompanied by instruments of transfer, in form satisfactory to the
Corporation or the Transfer Agent, duly executed by the holder of such shares or
the duly authorized representative of such holder, together with funds for the
payment of any transfer tax required pursuant to paragraph (e) of this
Subsection 3.

     b. Issuance of Certificates Representing Common Stock; Effectiveness of
Conversion. As promptly as practicable following the surrender for conversion of
a certificate representing shares of Class A and Class B Common Stock in the
manner provided in paragraph (a) of this Subsection 3, as applicable, any
required instruments of transfer and the payment in cash of any amount required
by the provisions of paragraph (e) of the Subsection 3, the Corporation shall
issue and deliver

                                      -3-
<PAGE>   4
or cause to be issued and delivered to such holder or such holder's nominee or
nominees, a certificate or certificates representing the number of shares of
Common Stock issued upon such conversion in such name or names as such holder
may direct. Mandatory Conversions shall be deemed to have been affected on the
Conversion Date on which the condition set forth in paragraph (a) of this
Subsection 3 is determined by the Board to have occurred. Upon the date the
conversion is deemed effected, all rights of the holder of such shares of Class
A or Class B Common Stock so converted, as the holder of such shares, shall
cease, and the person or persons in whose name or names the certificate or
certificates representing the shares of Class A or Class B Common Stock are
issued shall be treated for all purposes as having become the record holder or
holders of such shares of Common Stock on that date; provided, however, that if
any surrender and payment pursuant to a Mandatory Conversion occurs on any date
when the stock transfer books of the Corporation shall be closed, the person or
persons in whose name or names the certificate or certificates representing
shares of Common Stock are issued shall be deemed the record holder or holders
thereof for all purposes on the next succeeding day on which the stock transfer
books are open.

     c. Adjustments. No adjustments in respect of dividends shall be made upon
the Mandatory Conversion of any shares of Class A or Class B Common Stock;
provided, however, that if a share of Class A or Class B Common Stock shall be
converted subsequent to the record date for the payment of a dividend or other
distribution on Class A or Class B Common Stock but prior to such payment, then
the registered holder of such share of Class A or Class B Common Stock at the
close of business on such record date shall be entitled to receive the dividend
or other distribution payable on such share of Class A or Class B Common Stock
on such date notwithstanding the Mandatory Conversion thereof or the
Corporation's default in payment of the dividend due on such date.

     d. Availability of Common Stock for Conversion; Registration. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of issuance upon
conversion of the outstanding shares of Class A Common, Class B Common and
Series A Convertible Preferred Stock, such number of shares of Common Stock that
shall be issuable upon the conversion of all such shares of Class A Common,
Class B Common and Series A Convertible Preferred Stock then outstanding. If any
shares of Common Stock require registration with or approval of any governmental
authority under any federal or state law before such shares shall be issued upon
conversion, the Corporation shall cause such shares to be duly registered or
approved, as the case may be. All shares of Common Stock that shall be issued
upon conversion of the fully paid and nonassessable


                                      -4-
<PAGE>   5
     shares of Class A Common, Class B Common or Series A Convertible Preferred
     Stock shall, upon issue, be fully paid and nonassessable.

          e. Charges, Payment of Taxes upon Conversion. The issuance of
     certificates for shares of Common Stock issuable upon the Mandatory
     Conversion shall be made without charge to the converting holder; provided,
     however, that if any certificate is to be issued in a name other than that
     of the record holder of the shares being converted, the Corporation shall
     not be required to issue or deliver any such certificate unless and until
     the person requesting the issuance thereof shall have paid to the
     Corporation the amount of any tax that may be payable with respect to any
     transfer involved in the issuance and delivery of such certificate or has
     established to the satisfaction of the Corporation that such tax has been
     paid.

     4. Splits or Combinations. If the Corporation shall in any manner split,
subdivide or combine the outstanding shares of Class A Common Stock or Class B
Common Stock, then the outstanding shares of the other such class of Common
Stock shall be proportionately split, subdivided or combined in the same manner
and on the same basis as the outstanding shares of the class that has been
split, subdivided or combined.

     5. Mergers and Consolidations. In the event of a merger, consolidation or
combination of the Corporation with another entity (whether or not the
Corporation is the surviving entity), the holders of Class A Common Stock and
Class B Common Stock shall be entitled to receive the same per share
consideration in that transaction, except that any common stock that holders of
Class A Common Stock are entitled to receive in any such event may differ as to
voting rights and otherwise to the extent and only the extent that the Class A
Common Stock and the Class B Common Stock differ as set forth in this Section B.

     6. Liquidating Distributions. Upon any liquidation, dissolution or
winding-up of the Corporation, whether voluntary or involuntary, and after the
holders of the Preferred Stock shall have been paid in full the amounts to
which they shall be entitled, if any, or a sum sufficient for such payment in
full shall have been set aside, the remaining net assets of the Corporation, if
any, shall be divided among to the holders of Class A Common Stock and Class B
Common Stock pro rata based on the number of each class then outstanding,
provided, however, that in no event shall the holders of the Class A Common
Stock receive more than 20% of the remaining net assets and the holders of the
Class B Common Stock receive less than 80% of the remaining net assets.

     7. Sales and Repurchases. The Board shall have the power to cause the
Corporation to issue and sell shares of Class A or Class B Common Stock to such
individuals, partnerships, joint ventures, limited liability companies,
associations, corporations, trusts or other legal entities (collectively,
"persons") and for such


                                      -5-
<PAGE>   6
consideration as the Board shall from time to time in its discretion determine,
whether or not greater consideration could be received upon the issue or sale
of the same number of shares of the other class of Common Stock, and as
otherwise permitted by law. The Board shall have the power to cause the
Corporation to purchase, out of funds legally available therefor, shares of
either class of Common Stock from such persons and for such consideration as
the Board shall from time to time in its discretion determine, whether or not
less consideration could be paid upon the purchase of the same number of shares
of the other class of Common Stock, and as otherwise permitted by law.

         C.  Provisions Relating to Preferred Stock. Shares of Preferred Stock
may be issued from time to time in one or more series. The Board of Directors
is authorized to fix the number of shares in each series, the designation
thereof and the relative rights, preferences and limitations of each series
including, but not limited to: (a) the dividend rate; (b) redeemable features,
if any; (c) rights upon liquidation; (d) whether or not the shares of such
series shall be subject to a purchase, retirement or sinking fund provision;
(e) whether or not the shares of such series shall be convertible into or
exchangeable for shares of any other class and, if so, the rate of conversion
or exchange; (f) restrictions, if any, upon the payment of dividends on Common
Stock; (g) restrictions, if any, upon the creation of indebtedness; (h) voting
powers, if any, of the shares of each series; and (i) such other rights,
preferences and limitations as shall not be inconsistent with the laws of the
State of Florida.

         The holders of the Preferred Stock shall be entitled to dividends
thereon at the rate established by the Board of Directors. All remaining
profits which the Board of Directors may determine to apply in payment of
dividends shall be distributed among the holders of Common Stock exclusively.
Upon dissolution, whether voluntary or involuntary, the holders of Preferred
Stock shall first be entitled to receive, out of the net assets of the
Corporation, the liquidating value established by the Board of Directors, of
their shares plus unpaid accumulated dividends and any other distributions
declared thereon.

         D.   Share Reclassification. Immediately upon the filing hereof, each
then outstanding share of the Corporation's Common Stock (the "Existing Common
Stock") shall, automatically and without any action by the holder, be
reclassified and converted into 194,633 validly issued, fully paid and
nonassessable shares of Class A Common Stock. Each certificate that theretofore
represented shares of Existing Common Stock shall thereafter represent the
number of shares of Class A Common Stock into which the shares of Existing
Common Stock represented by such certificate were reclassified and converted
hereby; provided, however, that each person holding of record a stock
certificate or certificates that represented shares of Existing Common Stock
shall receive, upon surrender of each such certificate or certificates, a new
certificate or certificates evidencing and representing the number of shares of
Class A Common Stock to which such person is entitled. Upon consummation of the
reclassification of the Existing Common Stock of the Corporation provided for
in this Section D (the "Reclassification"), the holders of the Class A Common
Stock of the Corporation shall


                                      -6-
<PAGE>   7
have all rights accorded them by law and these Articles of Incorporation. The
issuance of certificates representing shares of Class A Common Stock issuable
upon the Reclassification shall be made without charge to the holders of
Existing Common Stock; provided, however, that if any certificate is to be
issued in a name other than that of the record holder of the shares of Existing
Common Stock being reclassified pursuant to and Reclassification, the
Corporation shall not be required to issue or deliver any such certificate
unless and until the person requesting the issuance thereof shall have paid to
the Corporation the amount of any tax that may be payable with respect to any
transfer involved in the issuance and delivery of such certificate or has
established to the satisfaction of the Corporation that such tax has been paid.
If so required by the Corporation or the Transfer Agent, any certificate for
shares of Existing Common Stock surrendered in connection with the
Reclassification shall be accompanied by instruments of transfer, in form
satisfactory to the Corporation or the Transfer Age, duly executed by the holder
of such shares or the duly authorized representative of such holder, together
with funds for payment of any transfer tax required as set forth above. As
promptly as practicable following the surrender of a certificate representing
shares of Class A Common Stock in the foregoing manner, any required instruments
of transfer and the payment in cash of any amount for the payment of any
transfer tax, the Corporation shall issue and deliver or cause to be issued and
delivered to such holder or such holder's nominee or nominees, a certificate or
certificates representing the number of shares of Class A Common Stock issued
upon the Reclassification to which such holder is entitled, in such name or
names as such holder may direct.

                       ARTICLE VII - BOARD OF DIRECTORS

          The number of directors shall be determined by the Board of Directors
in accordance with the Bylaws of the Corporation and shall consist of not less
than 5, nor more than 11 members. A director shall hold office until the annual
meeting for the year in which his terms expires and until his successor shall be
elected and shall qualify, subject, however, to prior death, resignation,
retirement, disqualification or removal from office in accordance with the
Bylaws of the Corporation.

                   ARTICLE VIII - CONTROL- SHARE ACQUISITIONS

          The Corporation elects not to be governed by Florida Statute Section
607.0902, as amended, relating to control-share acquisitions (the "Control-Share
Act"). The Corporation is expressly authorized to the fullest extent
permitted by the Control-Share Act to redeem control shares acquired in a
control-share acquisition at the fair value thereof pursuant to procedures
adopted by the Board of Directors.

                      ARTICLE IX - AFFILIATED TRANSACTIONS

          The Corporation elects not to be governed by Florida Statutes Section
607.0901, as amended, concerning affiliated transactions.

                         ARTICLE X - DIRECTOR LIABILITY

         A director of the Corporation shall not be personally liable to the
Corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director, except to the extent that such exemption from liability or
limitation thereof is not permitted under the Florida Business Corporation Act
as currently in effect or as the same may hereafter be amended. No amendment,
modification or repeal of this Article X (including any amendment or repeal of
this Article X made by virtue of any change in the Florida Business Corporation
Act after the date hereof) shall adversely affect any right or protection of a
director that exists at the time of such amendment, modification or repeal on
account of any action taken or any failure to act by such director prior to such
time.

         IN WITNESS WHEREOF, the undersigned has executed these Articles of
Incorporation this 31st day of March, 1998.

         The undersigned, William J. Mercurio, President and Chief Executive
Officer of NORTH AMERICAN TEL-COM GROUP, INC., a Florida corporation (the

                votes cast by the shareholders being sufficient for such
                approval, in accordance with Sections 607.1003 and 607.1006 of
                the Florida Statutes, the amendment and restatement of the

         2.     The undersigned officer of the Corporation has been duly
                authorized to submit these Amended and Restated Articles of
                Incorporation of the Corporation to the Department of State of

<PAGE>   10
                                   Exhibit A

                       NORTH AMERICAN TEL-COM GROUP, INC.

                    DESCRIPTION OF SERIES A PREFERRED STOCK


         1.   Designation. The 100,000 shares of Series A Convertible Preferred
Stock, par value $.01 per share (the "Preferred Stock"), shall have the
following rights, terms and privileges (terms used herein and not otherwise
defined shall have the meanings set forth in the Purchase Agreement (as
referred to below)):

         2.   Dividends.

              (a) Dividends. The holders of the then outstanding shares of
Preferred Stock shall be entitled to receive, out of funds legally available
therefor, cumulative annual dividends when as may be declared from time to time
by the Board of Directors of the Company at an annual rate per share equal to
eight percent (8%) of the original purchase price paid per share of the
Preferred Stock. Such amount shall be compounded annually such that if the
dividend is not paid for such year the unpaid amount shall be added to the
original purchase price paid per share of the Preferred Stock for purposes of
calculating succeeding years' dividends. Such dividends shall be deemed to
accrue on the Preferred Stock and be cumulative, whether or not earned or
declared and whether or not there are profits, surplus or other funds of the
Company legally available for the payment of dividends. If such cumulative
dividends in respect of any prior or current annual dividend period shall not
have been declared and paid, or there shall not have been a sum sufficient for
the payment therefor set apart, the deficiency shall first be fully paid before
any dividend or other distribution shall be paid or declared and set apart with
respect to any class of the Company's capital stock, now or hereafter
outstanding. Anything contained herein to the contrary notwithstanding, the
accrued dividends shall be immediately due and payable in cash, upon the
earliest occurrence of any of the following (each a "Dividend Date"):

                  (1) A Public Offering (as hereafter defined);

                  (2) A sale of the Company or a sale of all or substantially
all of the Company's assets; or

                  (3) April 15, 2005.

For purposes of this Section 2, unless the context requires otherwise,
"distribution" shall mean the transfer of cash or property without
consideration, whether by way of dividend or otherwise, or the purchase or
redemption of shares of capital stock of the Company for cash or property,
including any such transfer, purchase or redemption by a subsidiary of the
Company. Notwithstanding the foregoing, the Company shall not declare or pay a
dividend on the Preferred Stock prior to the Dividend Date.

              (b) Dividends in Kind. In the event the Company shall make or
issue, or shall fix a record date for the determination of holders of common
stock entitled to receive, a dividend or other distribution with respect to the
common stock payable in (i) securities of the Company other than shares of
common stock or (ii) assets, then and in each such event the holders of

<PAGE>   11
Preferred Stock shall receive, at the same time such distribution is made with
respect to common stock, the number of securities or such other assets of the
Company which they would have received had their Preferred Stock been converted
into common stock immediately prior to the record date for determining holders
of common stock entitled to receive such distribution.

     3. Liquidation, Dissolution or Winding Up

        a. Treatment at Liquidation, Dissolution or Winding Up.

           In the event of any liquidation, dissolution or winding up of the
Company, whether voluntary or involuntary, the holders of each share of
Preferred Stock shall be entitled to be paid out of the assets of the Company
available for distribution to holders of the Company's capital stock of all
classes, whether such assets are capital, surplus, or capital earnings, such
amount per share of Preferred Stock as would have been payable had each such
share been converted into common stock immediately prior to such event of
liquidation, dissolution or winding up pursuant to the provisions of Section 5
(the "Liquidation Amount") and the holders of the Preferred Stock shall be
treated as if they had converted the Preferred Stock into common stock.

        b. Distributions in Cash. The Liquidation Amount shall in all events be
paid in cash. Whenever a distribution provided for in this Section 3 is payable
in property other than cash, the value of such distribution shall be the fair
market value of such property as determined in good faith by the Company's
Board of Directors.

     4. Voting Power. Except as otherwise expressly provided in Section 8
hereof, or as required by law, each holder of Preferred Stock shall be entitled
to vote on all matters and shall be entitled to that number of votes equal to
the largest number of whole shares of common stock into which such holder's
shares of Preferred Stock, could be converted, pursuant to the provisions of
Section 5 hereof, at the record date for the determination of shareholders
entitled to vote on such matter or, if no such record date is established, at
the date such vote is taken or any written consent of shareholders is
solicited. Except as otherwise expressly provided herein or as required by law,
the holders of shares of Preferred Stock and common stock shall vote together
as a single class on all matters.

     5. Conversion Rights for the Preferred Stock. The holders of the Preferred
Stock shall have following rights with respect to the conversion of the
Preferred Stock into shares of Common Stock:

        (a) General. Subject to and in compliance with the provisions of this
Section 5, all but not less than all of the shares of the Preferred Stock may,
at the option of the holder, be converted at any time into fully-paid and
non-assessable shares of Common Stock; provided, however, that the conversion
must be done simultaneously with the conversion of the Note. The number of
shares of Common Stock to which a holder of Preferred Stock shall be entitled
upon conversion shall be the product obtained by multiplying the Applicable
Conversion Rate (determined as provided in Section 5(b)) by 100,000 (i.e., the
number of shares of Preferred Stock being converted).

         (b)  Applicable Conversion Rate. The conversion rate in effect at any
time (the "Applicable Conversion Rate") shall be the quotient obtained by
dividing $114.34688 by the Applicable Conversion Value, calculated as provided
in Section 5(c).

         (c)  Applicable Conversion Value. The Applicable Conversion Value
shall be $5.00, except that such amount shall be adjusted from time to time in
accordance with this Section 5.

         (d)  Adjustments to Applicable Conversion Values.

             (i)  (A) Fiscal Year 1999 Adjustment. If the EBITDA of Mich-Com
      Cable Services Incorporated, a Michigan corporation, Cablemasters Corp., a
      Pennsylvania corporation, Excel Cable Construction, a Florida corporation
      and Kenya Corporation, a Kansas corporation (the "Acquired Corporations")
      for the twelve months ended December 31, 1999 is less that $10,215,000
      (i.e., 80% of the 1999 budget), then the Applicable Conversion Rate shall
      be increased to a number that causes the holders of the Preferred Stock to
      increase the number of shares of the common stock of the Company on a
      fully diluted basis they would receive upon conversion of the Preferred
      Stock by ten percent (10%) of the Company's fully diluted number of shares
      (e.g., from 23.5% of the common stock to 33.5% of the common stock). If
      the EBITDA of the Acquired Corporations for the twelve months ended
      December 31, 1999 is less than $11,492,000 (i.e., 90% of the 1999 budget),
      but greater than $10,215,000, then the Applicable Conversion Rate shall be
      increased to a number that causes the holders of the Preferred Stock to
      increase the number of shares of common stock of the Company on a fully
      diluted basis they would receive upon conversion of the Preferred Stock by
      a pro rated portion of ten percent (10%) equal to the percentage by which
      the Acquired Corporation's EBITDA as a percentage of the 1999 budget was
      less than 90% of the 1999 budget (for example, if the EBITDA is 83% of the
      1999 budget, then 83% is 7% less than 90% and the holder shall be entitled
      to receive 23.5% plus 7% of the common stock upon such conversion). The
      adjustment in this Section 5(d)(i)(A) shall be computed based upon the
      audited financial statements of the Company for fiscal 1999 and shall be
      effective upon delivery of calculation of the foregoing by the Company's
      independent accountants, in the absence of computational error. The term
      "EBITDA" shall mean the Acquired Corporations' earnings before interest,
      taxes, depreciation, amortization (excluding extraordinary gains and
      losses, and any earnings or losses of any businesses or assets acquired
      after the date hereof), and prior to any deduction for non-cash charges
      relating to stock grants, any of the Company's corporate overhead charges
      or any management fees, all calculated based upon generally accepted
      accounting principles, consistently applied.

              (B) Upon Sale of Common Stock. If the Company shall, while there
      are any shares of Preferred Stock outstanding, issue or sell (or in
      accordance with Section 5(d)(i)(C) below is deemed to have issued or sold)
      shares of its common stock without consideration or at a price per share
      less than the Applicable Conversion Value in effect immediately prior to
      such issuance or sale, then in each such case such Applicable Conversion
      Value for the Preferred Stock, upon each such issuance or sale, except as


                                       3
<PAGE>   13
     hereinafter provided, shall be lowered so as to be equal to an amount
     determined by multiplying the Applicable Conversion Value by a fraction:

                 (1) the numerator of which shall be (a) the number of shares of
     common stock outstanding immediately prior to the issuance of such
     additional shares of common stock, plus (b) the number of shares of common
     stock which the net aggregate consideration, if any, received by the
     Company for the total number of such additional shares of common stock so
     issued would purchase at the Applicable Conversion Value in effect
     immediately prior to such issuance, and

                 (2) the denominator of which shall be (a) the number of shares
     of common stock outstanding immediately prior to the issuance of such
     additional shares of common stock plus (b) the number of such additional
     shares of common stock so issued.

            (C) Upon Issuance of Warrants, Options and Rights to Common Stock.

                (1) For the purposes of this Section 5(d)(i), the issuance of
     any warrants, options, subscriptions, or purchase rights with respect to
     shares of common stock and the issuance of any securities convertible into
     or exchangeable for shares of common stock (or the issuance of any
     warrants, options or any rights with respect to such convertible or
     exchangeable securities) shall be deemed an issuance of such common stock
     at such time if the Net Consideration Per Share (as hereinafter determined)
     which may be received by the Company for such common stock shall be less
     than the Applicable Conversion Value at the time of such issuance. Any
     obligation, agreement, or undertaking to issue warrants, options,
     subscriptions, or purchase rights at any time in the future shall be deemed
     to be an issuance at the time such obligation, agreement or undertaking is
     made or arises. No adjustment of the Applicable Conversion Value shall be
     made under this Section 5(d)(i) upon the issuance of any shares of common
     stock which are issued pursuant to the exercise of any warrants, options,
     subscriptions, or purchase rights or pursuant to the exercise of any
     conversion or exchange rights in any convertible securities if any
     adjustment shall previously have been made or deemed not required
     hereunder, upon the issuance of any such warrants, options, or subscription
     or purchase rights or upon the issuance of any convertible securities (or
     upon the issuance of any warrants, options or any rights therefor) as
     provided above.

     Should the Net Consideration Per Share of any such warrants, options,
     subscriptions, or purchase rights or convertible securities be decreased
     from time to time, then, upon the effectiveness of each such change, the
     Applicable Conversion Value shall be adjusted to such Applicable Conversion
     Value as would have obtained (1) had the adjustments made upon the issuance
     of such warrants, options, rights, or convertible securities been made upon
     the basis of the decreased Net Consideration per share of such securities,
     and (2) had adjustments made to the Applicable Conversion Value since the
     date of issuance of such securities been made to the Applicable Conversion
     Value as adjusted pursuant to (1) above.


                                       4
<PAGE>   14
                        (2) For purposes of this paragraph, the "Net
Consideration Per Share" which may be received by the Company shall be
determined as follows:

                            (i) The "Net Consideration Per Share" shall mean the
        amount equal to the total amount of consideration, if any, received by
        the Company for the issuance of such warrants, options, subscriptions,
        or other purchase rights or convertible or exchangeable securities, plus
        the minimum amount of consideration, if any, payable to the Company upon
        exercise or conversion thereof, divided by the aggregate number of
        shares of common stock that would be issued if all such warrants,
        options, subscriptions, or other purchase rights or convertible or
        exchangeable securities were exercised, exchanged, or converted.

                            (ii) The "Net Consideration Per Share" which may be
        received by the Company shall be determined in each instance as of the
        date of issuance of warrants, options, subscriptions, or other purchase
        rights or convertible or exchangeable securities without giving effect
        to any possible future upward price adjustments or rate adjustments
        which may be applicable with respect to such warrants, options,
        subscriptions, or other purchase rights or convertible or exchangeable
        securities.

            (D) Stock Dividends. In the event the Company shall make or issue a
dividend or other distribution payable in common stock or securities of the
Company convertible into or otherwise exchangeable for the common stock of the
Company, then such common stock or other securities issued in payment of such
dividend shall be deemed to have been issued without consideration (except for
dividends payable in shares of common stock payable pro rata to holders of
Preferred Stock and to holders of any other class of stock).

            (E) Consideration Other than Cash. For purposes of this Section
5(d), if a part or all of the consideration received by the Company in
connection with the issuance of shares of the common stock or the issuance of
any of the securities described in this Section 5(d) consists of property other
than cash, such consideration shall be deemed to have a fair market value as is
reasonably determined in good faith by the Board of Directors of the Company.

            (F) Shares Issued Pursuant to Additional Acquisitions. For the
purposes of the calculation of adjustments to the Applicable Conversion Rate or
Value pursuant to this Section 5(d), until such time that the Company has
issued 1.8 million shares of common stock or common stock equivalents (beyond
those outstanding on the date hereof) pursuant to the acquisitions of other
companies from independent third parties, upon the issuance of any additional
shares hereafter (and only until such 1.8 million additional shares are issued)
the Applicable Conversion Rate or Value shall be adjusted so that the holders
of the Preferred Stock will continue to have the right to convert the Preferred
Stock into the same percentage of the Company's common stock as


                                       5
<PAGE>   15

         if such issuance of common stock had not occurred, and therefore the
         holder of the Preferred Stock shall not be diluted by the issuance of
         such additional common stock or common stock equivalents.

                    (G) Exceptions. This Section 5(d)(i) shall not apply under
         any of the circumstances which would constitute an Extraordinary Common
         Stock Event (as hereinafter defined in Section 5(d)(ii)). Further, the
         provisions of this Section 5(d) shall not apply to (i) shares issued
         upon conversion of the Preferred Stock shares issues upon conversion of
         a Note, or (ii) the issuance of any common stock pursuant to the
         exercise of the options (and the shares issuable upon exercise thereof)
         to purchase up to an aggregate of 500,000 shares of common stock
         (including options outstanding on the date hereof) issued to employees
         of the Company, as provided in Section 8.7 of that certain Securities
         Purchase Agreement, dated as of March 31, 1998 (the "Purchase
         Agreement"). The number of shares in this Section (G) shall be
         proportionately adjusted to reflect any stock dividend, stock split or
         other form of recapitalization occurring after the date hereof.

               (ii) Upon Extraordinary Common Stock Event. Upon the happening of
an Extraordinary Common Stock Event (as hereinafter defined), the Application
Conversion Value for the Preferred Stock shall, simultaneously with the
happening of such Extraordinary Common Stock Event, be adjusted by multiplying
the then effective Applicable Conversion Value with respect to the Preferred
Stock by a fraction, the numerator of which shall be the number of shares of
common stock outstanding immediately prior to such Extraordinary Common Stock
Event and the denominator of which shall be the number of shares of common stock
outstanding immediately after such Extraordinary Common Stock Event, and the
products so obtained shall thereafter be the Applicable Conversion Value. The
Applicable Conversion Value for the Preferred Stock shall be readjusted in the
same manner upon the happening of any successive Extraordinary Common Stock
Event or Events.

                    "Extraordinary Common Stock Event" shall mean (i) the issue
         of additional shares of common stock as a dividend or other
         distribution on outstanding common stock or on any class or series of
         preferred stock, unless made pro rata to holders of Preferred Stock,
         (ii) a subdivision of outstanding shares of common stock into a greater
         number of shares of common stock, or (iii) a combination of outstanding
         shares of the common stock into a smaller number of shares of common
         stock.

         (e) Dividends. In the event the Company shall make or issue, or shall
fix a record date for the determination of holders of common stock entitled to
receive, a dividend or other distribution with respect to the common stock
payable in (i) securities of the Company other than shares of common stock or
(ii) assets, then and in each such event the holders of Preferred Stock shall
receive, at the same time such distribution is made with respect to common
stock, the number of securities or such other assets of the Company which they
would have received had their Preferred Stock been converted into common stock
immediately prior to the date of such distribution.

         (f) Capital Reorganization or Reclassification. If the common stock
issuable upon the conversion of the Preferred Stock shall be changed into the
same or different number of





                                       6
<PAGE>   16
shares of any class or classes of stock, whether by capital reorganization,
reclassification or otherwise (other than a subdivision or combination of
shares or stock dividend provided for elsewhere in this Section 5 or by a
Reorganization), then and in each such event, the holder of each share of
Preferred Stock shall have the right thereafter to convert such share into the
kind and amount of shares of stock and other securities and property receivable
upon such capital reorganization, reclassification or other change by holders of
the number of shares of Common Stock into which such shares of Preferred Stock
might have been converted immediately prior to such capital reorganization,
reclassification or other change.

         (g)  Capital Reorganization, Merger or Sale of Assets. If at any time
or from time to time there shall be a capital reorganization of the common stock
(other than a subdivision, combination, reclassification or exchange of shares
provided for elsewhere in this Section 5) or a merger or consolidation of the
Company with or into another corporation, or the sale of all or substantially
all of the Company's properties and assets to any other person, or any
transaction or series of related transactions in which more than fifty percent
(50%) of the outstanding voting securities of the Company (on an as converted
basis) is sold or assigned (any of which events is herein referred to as a
"Reorganization"), then as a part of such Reorganization, provision shall be
made so that the holders of the Preferred Stock shall thereafter be entitled to
receive upon conversion of the Preferred Stock, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such Reorganization, to which such holder would have been
entitled if such holder had converted its shares of Preferred Stock immediately
prior to such Reorganization. In any such case, appropriate adjustment shall be
made in the application of the provisions of this Section 5 with respect to the
rights of the holders of the Preferred Stock after the Reorganization, to the
end that the provisions of this Section 5 (including adjustment of the
Applicable Conversion Value then in effect and the number of shares issuable
upon conversion of the Preferred Stock) shall be applicable after that event in
as nearly equivalent a manner as may be practicable.

         (h)  Certificate as to Adjustments; Notice by Company. In each case of
an adjustment or readjustment of the Applicable Conversion Rate, the Company at
its expense will furnish each holder of Preferred Stock with a certificate,
executed by the president and chief financial officer (or in the absence of a
person designated as the chief financial officer, by the treasurer) showing such
adjustment or readjustment, and stating in detail the facts upon which such
adjustment or readjustment is based.

         (i)  Exercise of Conversion Privilege. To exercise its conversion
privilege, a holder of Preferred Stock shall surrender the certificate or
certificates representing the shares being converted to the Company at its
principal office, and shall give written notice to the Company at that office
that such holder elects to convert such shares. Such notice shall also state the
name or names (with address or addresses) in which the certificate or
certificates for shares of Common Stock issuable upon such conversion shall be
issued. The certificate or certificates for shares of Preferred Stock
surrendered for conversion shall be accompanied by proper assignment thereof to
the Company or in blank. The date when such written notice is received by the
Company, together with the certificate or certificates representing the shares
of Preferred Stock being converted, shall be the "Conversion Date." As promptly
as practicable after the Conversion Date, the Company shall issue and shall
deliver to the holder of the shares of Preferred Stock



                                       7
<PAGE>   17
being converted, or on its written order, such certificate or certificates as it
may request for the number of whole shares of common stock issuable upon the
conversion of such shares of Preferred Stock in accordance with the provisions
of this Section 5, and cash, as provided in Section 5(j), in respect of any
fraction of a share of Common Stock issuable upon such conversion.  Such
conversion shall be deemed to have been effected immediately prior to the close
of business on the Conversion Date, and at such time the rights of the holder as
holder of the converted shares of Preferred Stock shall cease and the person or
persons in whose name or names any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become the holder or holders of record of the shares of Common Stock represented
thereby. The Company shall pay any taxes payable with respect to the issuance of
Common Stock upon conversion of the Preferred Stock, other than any taxes
payable with respect to income by the holders thereof.

          (j)  Cash in Lieu of Fractional Shares. The Company may, if it so
elects, issue fractional shares of Common stock or scrip representing fractional
shares upon the conversion of shares of Preferred Stock.  If the Company does
not elect to issue fractional shares, the Company shall pay to the holder of the
shares of Preferred Stock which were converted a cash adjustment in respect of
such fractional shares in an amount equal to the same fraction of the market
price per share of the Common Stock (as determined in a reasonable manner
prescribed by the Board of Directors) at the close of business on the
Conversion Date.  The determination as to whether or not any fractional shares
are issuable shall be based upon the total number of shares of Preferred Stock
being converted at any one time by any holder thereof, not upon each share of
Preferred Stock being converted.

          (l)  Reservation of Common Stock.  The Company shall at all times
reserve and keep available out of its authorized but unissued shares of Common
Stock, solely for the purpose of effecting the conversion of the shares of the
Preferred Stock, such number of its shares of Common stock as shall from time to
time be sufficient to effect the conversion of all outstanding shares of the
Preferred Stock, and if at any time the number of authorized but unissued shares
of Common Stock shall not be sufficient to effect the conversion of all then
outstanding shares of the Preferred Stock, the Company shall take such corporate
action as may be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purpose.

     6.   No Reissuance of Preferred Stock.  No share or shares of Preferred
Stock acquired by the Company by reason of redemption, purchase, conversion or
otherwise shall be reissued, and all such shares shall be canceled, retired and
eliminated from the shares which the Company shall be authorized to issue.  The
Company may from time to time take such appropriate corporate action as may be
necessary to reduce the authorized number of shares of the Preferred Stock
accordingly.

     7.   Redemption

          (a)  Optional Redemption Upon Qualified Public Offering. Effective
upon the closing of a Qualified Public Offering (as hereinafter defined), the
Company may require the holders of the Preferred Stock to convert their
Preferred Stock into Common Stock and EBITDA



                                       8
<PAGE>   18
Options (as hereinafter defined) by sending notice thereof, together with a
calculation of the Applicable Conversion Value, at least ten business days
prior to the closing of the Qualified Public Offering, to all holders of
Preferred Stock.  The mandatory conversion shall be effective as of the closing
date of the Qualified Public Offering and on and after such date the
certificates representing the Preferred Stock shall only represent the right to
receive the Conversion Shares and EBITDA Options.  For purposes hereof, the
term "Qualified Public Offering" shall mean an underwritten public offering
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act"), covering the offer and sale of common
stock for the account of the Company in which the aggregate net proceeds to the
Company equal at least $25,000,000 and in which the price per share of common
stock is at least two and one half (2.5) times the then Applicable Conversion
Value of the Preferred Stock.

     "EBITDA Options" shall mean one or more option agreements to be executed
prior to a Qualified Public Offering by the Company in favor of the holders of
the Preferred Stock granting them the right to acquire the additional shares of
the Company's common stock that they may otherwise have received in the amounts
and on the terms and conditions as set forth in Section 5(d)(i)(A) had the
Preferred Stock not been redeemed by the Company, with an exercise price equal
to $.01 per share of common stock.

Nothing contained in Section 7(a) shall (i) in any way restrict or prohibit the
holders of the Preferred Stock from exercising their conversion
rights pursuant to Section 5 hereof prior to the effective date of the
redemption to be effected hereunder; provided, however, that any such
conversion under Section 7(a) may be subject to the closing of the Qualified
Public Offering.

     (b)  Optional Redemption by the Holder Following Default.

          (i)  In the event there is an Event of Default under the Purchase
Agreement and the applicable cure period, if any, has expired (a "Default"),
then the holders of at least fifty-one percent (51%) of the then outstanding
shares of Preferred Stock may request the Company to redeem any or all of the
shares of Preferred Stock then held by such holders at the price equal to the
greater of (i) the original purchase price of the Preferred Stock (as adjusted
to reflect any stock split, stock dividend or other form of recapitalization),
together with all accrued and unpaid dividends (whether or not declared)
thereon to be calculated and paid through and including the date of redemption
or (ii) fair market value thereof, as of the date of such proposed redemption,
as determined, at the Company's sole expense, by a nationally recognized
investment banking firm (mutually acceptable to both the Company and the
Holders), taking into account, in valuing such Shares, all relevant facts and
circumstances; provided, however, that there shall be valuing such Shares, all
relevant facts and circumstances; provided, however,

that there shall be no discount to reflect the fact that the Shares represent a
minority interest in the Company (the "Holder Redemption Price"). Such request
(the "Default Redemption Request") shall be submitted to the Company in writing
within thirty (30) days after the Company notifies all of the holders of the
Preferred Stock in writing of the Default. No cure of such Default during such
thirty (30) day period shall vitiate such Default Redemption request and the
failure to make such a Default Redemption Request within such thirty (30) day
period shall not result in the waiver of such remedy.


                                       9
<PAGE>   19
          (ii) Upon receipt of a Default Redemption Request, the Company shall
promptly give notice thereof (the "Default Redemption Notice") to each holder of
Preferred Stock. Such Default Redemption Notice shall specify the number of
shares of Preferred Stock covered by the Default Redemption Request and the
Holder Redemption Price to be paid with respect thereto. Any holder of
Preferred Stock who wishes to join in the Default Redemption Request may do so
by so advising the Company in writing within 15 days after receipt of the
Default Redemption Notice specified in the preceding sentence. No holder of
Preferred Stock shall be required to participate in such redemption. The
Company shall redeem all shares of Preferred Stock covered by the Default
Redemption Request (including those held by holders who have requested a
redemption following receipt of the Default Redemption Notice) at a closing to
be held not more than thirty (30) days after the date of the Default Redemption
Request. At the closing, the Company shall pay for the shares of Preferred
Stock so redeemed in an amount equal to the Holder Redemption Price, payable in
cash.

     (c)  Optional Redemption by Holders. At the election of the holders of at
least fifty-one percent (51%) of the then outstanding shares of Preferred
Stock, the Company shall, to the extent it may do so under applicable law,
redeem pro rata from all holders of Preferred Stock on April 15, 2005 the
shares of Preferred Stock outstanding on the date of such redemption (the
"Final Redemption Date"). The Company shall give the holders of the Preferred
Stock at least ninety (90) days' notice of the Final Redemption Date (the
"Final Redemption Notice"). In the event that the Company does not provide the
Final Redemption Notice, the option of the holders of the Preferred Stock to
require the Company to redeem the remaining shares of Preferred Stock on the
Final Redemption Date shall be extended beyond the Final Redemption Date to a
date which is ninety (90) days from the date that the Company elects to mail
the Final Redemption Notice. In the event shares of Preferred Stock scheduled
for redemption are not redeemed because of a prohibition under applicable law,
such shares shall be redeemed as soon as such prohibition no longer exists. The
redemption price for each share of Preferred Stock redeemed pursuant to this
Section 7(c) shall be equal to the Holder Redemption Price.

     In the event that the holders of the Preferred Stock do not elect to have
the Preferred Stock redeemed pursuant to this Section 7(c), the shares of
Preferred Stock shall remain outstanding and subject to the rights and
preferences contained herein.

     (d)  Redemption Notice. If an election is made pursuant to Section 7(c)
hereof, written notice of such election shall be mailed, postage prepaid, to
the Company, not later than sixty (60) days before the date fixed for each
redemption pursuant to Section 7(c) or, in the event the Company does not
provide the Final Redemption Notice pursuant to Section 7(c) hereof, not later
than sixty (60) days before the date that the Final Redemption Date has been
extended as provided in Section 7(c) (each of the dates fixed for redemption
and the extended redemption date is hereinafter referred to as a "Redemption
Date"). If such election is made and appropriate notice is given, then, at
least forty-five (45) days before the Redemption Date, written notice
(hereinafter referred to as the "Redemption Notice") shall be mailed by the
Company, postage prepaid, to each holder of record of Preferred Stock at its
address shown on the records of the Company; provided, however, that the
Company's failure to give such Redemption Notice shall in no way affect its
obligation to redeem the shares of Preferred Stock or the obligation of the
holders to redeem their shares of Preferred Stock as provided in Section 7(c)
hereof. The



                                       10
<PAGE>   20
Redemption Notice shall contain (i) the number of shares of Preferred Stock
held by the holder and the total number of shares of Preferred Stock held by
all holders subject to redemption as of such Redemption Date; and (ii) the
Redemption Date and the applicable Holder Redemption Price. Any holder of
Preferred Stock who wishes to do so may, by giving notice to the Company prior
to the Redemption Date, convert into common stock any or all of the shares of
Preferred Stock held by him and scheduled for redemption on such Redemption
Date.

        (e) Surrender of Certificates. Each holder of shares of Preferred Stock
to be redeemed under this Section 7 shall surrender the certificate or
certificates representing such shares to the Company at the place designated in
the Redemption Notice, and thereupon the Company Redemption Price or Holder
Redemption Price, as the case may be, for such shares as set forth in this
Section 7 shall be paid to the order of the person whose name appears on such
certificate or certificates. Irrespective of whether the certificates therefor
shall have been surrendered, all shares of Preferred Stock which are the subject
of a Redemption Notice shall be deemed to have been redeemed and shall be
canceled effective as of the Redemption Date, unless the Company shall default
in the payment of the applicable Redemption Price.

        (f) Sale of the Company. In lieu of the redemption obligations of the
Company as set forth herein, the Company may instead retain a nationally
recognized investment banking firm (or other mutually acceptable party) to sell
the Company, provided that the Company acts expeditiously and in good faith and
the sale of the Company is consummated no later than 180 days after the required
date of redemption.

     8. Restrictions and Limitations.

        (a) Corporate Securities Action. Except as expressly provided herein or
as required by law, so long as any shares of Preferred Stock remain outstanding,
the Company shall not, and shall not permit any subsidiary (which shall mean any
corporation, association or other business entity which the Company and/or any
of its other subsidiaries directly or indirectly owns at the time more than
fifty percent (50%) of the outstanding voting shares of such corporation or
trust, other than directors' qualifying shares) to, without the approval by vote
or written consent by the holders of at least a majority of the then outstanding
shares of Preferred Stock, voting as a separate class:

            (i) redeem, purchase or otherwise acquire for value (or pay into or
set aside for a sinking fund for such purpose), or declare and pay or set aside
funds for the payment of any dividend with respect to, any share or shares of
capital stock, except as required or permitted hereunder or under the terms of
Section 4.2 of the Purchase Agreement;

            (ii) authorize or issue, or obligate itself to authorize or issue,
additional shares of Preferred Stock;

            (iii) authorize or issue, or obligate itself to authorize or issue,
any equity security senior to or on parity with the Preferred Stock as to
liquidation preferences, dividend rights, or voting rights;

<PAGE>   21
                    (iv) merger or consolidate with any other corporation or
sell, assign, lease or otherwise dispose of or voluntarily part with the
control of (whether in one transaction or in a series of transactions) all, or
substantially all, of its assets (whether now owned or hereinafter acquired),
or consent to any liquidation, dissolution or winding up of the Company, or
permit any subsidiary to do any of the foregoing, except for (A) any
wholly-owned subsidiary may merge into or consolidate with or transfer assets
to any other wholly-owned subsidiary, and (B) any wholly-owned subsidiary may
merge into or transfer assets to the Company; or

                    (v) amend, restate, modify or alter the by-laws of the
Company in any way which adversely affects the rights of the holders of the
Preferred Stock.

          (b) Amendments to Charter. The Company shall not amend its Articles
of Incorporation without the approval, by vote or written consent, by the
holders of at least a majority of the then outstanding shares of Preferred
Stock, if such amendment would amend any of the rights, preferences, privileges
of or limitations provided for herein for the benefit of any shares of
Preferred Stock. Without limiting the generality of the preceding sentence, the
Company shall not amend its Articles of Incorporation without the approval by
the holders of at least a majority of the then outstanding shares of Preferred
Stock if such amendment would:

                    (i) change the relative seniority rights of the holders of
Preferred Stock as to the payments of dividends in relation to the holders of
any other capital stock of the Company, or create any other class or series of
capital stock entitled to seniority as to the payment of dividends in relation
to the holders of Preferred Stock;

                    (ii) reduce the amount payable to the holders of Preferred
Stock upon the voluntary or involuntary liquidation, dissolution or winding up
the Company, or change the relative seniority of the liquidation preferences
of the holders of Preferred Stock to the rights upon liquidation of the holders
of other capital stock of the Company, or change the dividend rights of the
holders of Preferred Stock;

                    (iii) cancel or modify the conversion rights of the holders
of Preferred Stock provided for in Section 5 herein;

                    (iv) cancel or modify the redemption rights of the holders
of the Preferred Stock provided for in Section 7 herein; or

                    (v) cancel or modify the rights of the holders of the
Preferred Stock provided for in this Section 8.

          9. No Dilution or Impairment. The Company shall not, by amendment of
its Articles of Incorporation or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of the Preferred Stock set forth herein, but shall at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate in order to
protect the rights of the holders of the Preferred Stock against dilution or
other impairment. Without limiting the generality of the



                                       12
<PAGE>   22
foregoing, the Company (a) shall not increase the par value of any shares of
stock receivable on the conversion of the Preferred Stock above the amount
payable therefor on such conversion, (b) shall take all such action as may be
necessary or appropriate in order that the Company may validly and legally
issue fully paid and nonassessable shares of stock on the conversion of all
Preferred Stock from time to time outstanding, and (c) shall not consolidate
with or merge into any other person or permit any such person to consolidate
with or merge into the Company (if the Company is not the surviving person),
unless such other person shall expressly assume in writing and will be bound by
all of the terms of the Preferred Stock set forth herein.

         10.  Notices of Record Date. In the event of any taking by the Company
of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend or
other distribution, or any right to subscribe for, purchase or otherwise
acquire any shares of stock of any class or any other securities or property,
or to receive any other right, or

              (a) any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company, any
merger of the Company, or any transfer of all or substantially all of the
assets of the Company to any other corporation, or any other entity or person,
or

              (b) any voluntary or involuntary dissolution, liquidation or
winding up of the Company,

then and in each such event the Company shall mail or cause to be mailed to each
holder of Preferred Stock a notice specifying (i) the date on which any such
record is to be taken for the purpose of such dividend, distribution or right
and a description of such dividend, distribution or right, (ii) the date on
which any such reorganization, reclassification, recapitalization, transfer,
merger, dissolution, liquidation or winding up is expected to become effective
and (iii) the time, if any, that is to be fixed, as to when the holders of
record of common stock (or other securities) shall be entitled to exchange their
shares of common (or other securities) for securities or other property
deliverable upon such reorganization, reclassification, recapitalization,
transfer, merger, dissolution, liquidation or winding up. Such notice shall be
mailed at least ten (10) business days prior to the date specified in such
notice on which such action is to be taken.

                       NORTH AMERICAN TEL-COM GROUP, INC.



                       ARTICLE I. MEETINGS OF SHAREHOLDERS

         SECTION 1. ANNUAL MEETING. The annual meeting of the shareholders of
the Corporation for the election of directors and the transaction of other
business shall be held on such date, at such time and in such place as shall be
determined by the board of directors. If any annual meeting is not held, by
oversight or otherwise, a special meeting shall be held as soon as practical,
and any business transacted or election held at that meeting shall be as valid
as if transacted or held at the annual meeting.

         SECTION 2. SPECIAL MEETINGS. Special meetings of the shareholders for
any purpose shall be held when called by the president or the board of
directors, or when demanded in writing by the holders of not less than ten
percent (unless a greater percentage not to exceed fifty percent is required by
the articles of incorporation) of all the shares entitled to vote at the
meeting. Such demand must be delivered to the Corporation's secretary. A meeting
demanded by shareholders shall be called for a date not less than ten nor more
than sixty days after the request is made, unless the shareholders requesting
the meeting designate a later date. The secretary shall issue the call for the
meeting, unless the president, the board of directors, or shareholders
requesting the meeting designate another person to do so. The shareholders at a
special meeting may transact only business that is related to the purposes
stated in the notice of the special meeting.

         SECTION 3. PLACE. Meetings of shareholders may be held either within or
outside the State of Florida.

         SECTION 4. NOTICE. A written notice of each meeting of shareholders,
stating the place, day, and time of the meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, shall be
delivered to each shareholder of record entitled to vote at the meeting, not
less than ten nor more than sixty days before the date set for the meeting,
either personally or by first-class mail, by or at the direction of the
president, the secretary, or the officer or other persons calling the meeting.
If mailed, the notice shall be considered delivered when it is deposited in the
United States mail, postage prepaid, addressed to the shareholder at his address
as it appears on the records of the Corporation.

<PAGE>   2

         SECTION 5. WAIVERS OF NOTICE. Whenever any notice is required to be
given to any shareholder of the Corporation under these bylaws, the articles of
incorporation, or the Florida Business Corporation Act, a written waiver of
notice, signed anytime by the person entitled to notice shall be equivalent to
giving notice. Attendance by a shareholder entitled to vote at a meeting, in
person or by proxy, shall constitute a waiver of (a) notice of the meeting,
except when the shareholder attends a meeting solely for the purpose, expressed
at the beginning of the meeting, of objecting to the transaction of any business
because the meeting is not lawfully called or convened, and (b) an objection to
consideration of a particular matter at the meeting that is not within the
purpose of the meeting unless the shareholders object to considering the matter
when it is presented.

         SECTION 6. RECORD DATE. For the purpose of determining the shareholders
for any purpose, the board of directors may either require the stock transfer
books to be closed for up to seventy days or fix a record date, which shall be
not more than seventy days before the date on which the action requiring the
determination is to be taken. However, a record date shall not precede the date
upon which the resolution fixing the record date is adopted. If the transfer
books are not closed and no record date is set by the board of directors, the
record date shall be determined as follows: For determining shareholders
entitled to demand a special meeting, the record date is the date the first such
demand is delivered to the Corporation; For determining shareholders entitled to
a share dividend, the record date is the date the board of directors authorizes
the dividend; If no prior action is required by the board of directors pursuant
to the Florida Business Corporation Act, the record date for determining
shareholders entitled to take action without a meeting is the date the first
signed written consent is delivered to the Corporation; If prior action is
required by the board of directors pursuant to the Florida Business Corporation
Act, the record date for determining shareholders entitled to take action
without a meeting is at the close of business on the day that the board of
directors adopts a resolution taking such prior action; and For determining
shareholders entitled to notice of and to vote at an annual or special
shareholders meeting the record date is as of the close of business on the day
before the first notice is delivered to the shareholders. When a determination
of the shareholders entitled to vote at any meeting has been made, that
determination shall apply to any adjournment of the meeting, unless the board of
directors fixes a new record date. The board of directors shall fix a new record
date if the meeting is adjourned to a date more than 120 days after the date
fixed for the original meeting.

         SECTION 7. SHAREHOLDER'S LIST FOR MEETING. A complete alphabetical
list of the names of the shareholders entitled to receive notice of and to vote
at the meeting shall be prepared by the secretary or other authorized agent
having charge of the stock transfer book. The list shall be arranged by voting
group and include each shareholder's address, and the number, series, and class
of shares held. The list must be made available at least ten days before and
throughout each meeting of shareholders, or such shorter time as exists between
the record date and the meeting. The list must


                                       2
<PAGE>   3

be made available at the Corporation's principal office, registered agent's
office, transfer agent's office or at a place identified in the meeting notice
in the city where the meeting will be held. Any shareholder, his agent or
attorney, upon written demand and at his own expense may inspect the list during
regular business hours. The list shall be available at the meeting and any
shareholder, his agent or attorney is entitled to inspect the list at any time
during the meeting or its adjournment.

         If the requirements of this section have not been substantially
complied with, the meeting, on the demand of any shareholder in person or by
proxy, shall be adjourned until the requirements of this section are met. If no
demand for adjournment is made, failure to comply with the requirements of this
section does not affect the validity of any action taken at the meeting.

         SECTION 8. SHAREHOLDER QUORUM AND VOTING. A majority of the shares
entitled to vote, represented in person or by proxy, constitutes a quorum at a
meeting of shareholders. If a quorum is present, the affirmative vote of a
majority of the shares entitled to vote on the matter is the act of the
shareholders unless otherwise provided by law. A shareholder may vote either in
person or by proxy executed in writing by the shareholder or his duly authorized
attorney-in-fact. After a quorum has been established at a shareholders'
meeting, a withdrawal of shareholders that reduces the number of shareholders
entitled to vote at the meeting below the number required for a quorum does not
affect the validity of an adjournment of the meeting or an action taken at the
meeting prior to the shareholders' withdrawal.

         Authorized but unissued shares including those redeemed or otherwise
reacquired by the corporation, and shares of stock of this Corporation owned by
another corporation the majority of the voting stock of which is owned or
controlled by this Corporation, directly or indirectly, at any meeting shall not
be counted in determining the total number of outstanding shares at any time.
The chairman of the board, the president, any vice president, the secretary, and
the treasurer of a corporate shareholder are presumed to possess, in that order,
authority to vote shares standing in the name of a corporate shareholder, absent
a bylaw or other instrument of the corporate shareholder designating some other
officer, agent, or proxy to vote the shares. Shares held by an administrator,
executor, guardian, or conservator may be voted by him without a transfer of the
shares into his name. A trustee may vote shares standing in his name, but no
trustee may vote shares that are not transferred into his name. If he is
authorized to do so by an appropriate order of the court by which he was
appointed, a receiver may vote shares standing in his name or held by or under
his control, without transferring the shares into his name. A shareholder whose
shares are pledged may vote the shares until the shares have been transferred
into the name of the pledgee, and thereafter the pledgee or his nominee shall be
entitled to vote the shares unless the instrument creating the pledge provides
otherwise.

                              ARTICLE II. DIRECTORS

         SECTION 1. FUNCTION. The business of this Corporation shall be managed
and its corporate powers exercised by the board of directors.

         SECTION 2. NUMBER. The Corporation shall have at least one (1) director
at all times. The number of directors may be increased or diminished from time
to time by action of the board of directors or shareholders, but no decrease
shall have the effect of shortening the term of any incumbent director, unless
the shareholders remove the director.

         SECTION 3. QUALIFICATION. Each member of the board of directors must be
a natural person who is eighteen years of age or older. A director need not be a
resident of Florida or a shareholder of the Corporation.

         SECTION 4. ELECTION AND TERM. The persons named in the articles of
incorporation as members of the initial board of directors shall hold office
until the first annual meeting of shareholders and until their successors have
been elected and qualified or until their earlier resignation, removal from
office, or death. At the first annual meeting of shareholders and at each annual
meeting thereafter the shareholders shall elect directors to hold office until
the next succeeding annual meeting. Each director shall hold office for the term
for which he is elected and until his successor is elected and qualifies or
until his earlier resignation, removal from office, or death.

         SECTION 5. COMPENSATION. The board of directors has authority to fix
the compensation of the directors, as directors and as officers.

         SECTION 6. DUTIES OF DIRECTORS. A director shall perform his duties as
a director, including his duties as a member of any committee of the board upon
which he serves, in good faith, in a manner he reasonably believes to be in the
best interests of the Corporation.

         SECTION 7. PRESUMPTION OF ASSENT. A director of the Corporation who is
present at a meeting of the board of directors or a committee of the board of
directors when corporate action is taken is presumed to have assented to the
action unless he votes against it or expressly abstains from voting on the
action taken, or, he objects at the beginning of the meeting to the holding of
the meeting or transacting specific business at the meeting.

         SECTION 8. VACANCIES. Unless filled by the shareholders, any vacancy
occurring in the board of directors, including any vacancy created because of an
increase in the number of directors, may be filled by the affirmative vote of a
majority of the remaining directors, even if the number of remaining directors
does not constitute a quorum of the board of directors. A director elected to
fill a vacancy shall hold office only until the next election of directors by
the shareholders.


                                        4
<PAGE>   5

         SECTION 9. REMOVAL OR RESIGNATION OF DIRECTORS. At a meeting of
shareholders called for that purpose, the shareholders, by a vote of the
holders of a majority of the shares entitled to vote at an election of
directors, may remove any director, or the entire board of directors, with or
without cause, and fill any vacancy or vacancies created by the removal.

         A director may resign at any time by delivering written notice to the
board of directors or its chairman or the corporation. A resignation is
effective when the notice is delivered unless the notice specifies later
effective date. If a resignation is made effective at a later date, the board of
directors may fill the pending vacancy before the effective date if the board of
directors provided that the successor does not take office until the effective
date.

         SECTION 10. QUORUM AND VOTING. A majority of the board of directors
constitutes a quorum for the transaction of business. The act of the majority of
the directors at a meeting at which a quorum is present is the act of the board
of directors.

         SECTION 11. PLACE OF MEETINGS. Regular and special meetings by the
board of directors may be held within or outside the State of Florida.

         SECTION 12. REGULAR MEETINGS. A regular meeting of the board of
directors shall be held without notice, other than this bylaw, immediately after
and at the same place as the annual meeting of shareholders. The board of
directors may provide, by resolution, the time and place for the holding of
additional regular meetings without notice other than the resolution.

         SECTION 13. SPECIAL MEETINGS. Special meetings of the board of
directors may be called by or at the request of the president or any directors.

         SECTION 14. NOTICE OF MEETINGS. Written notice of the time and place of
special meetings of the board of directors shall be given to each director by
either personal delivery or by first class United States mail, telegram, or
cablegram at least two days before the meeting. Notice of a meeting of the board
of directors need not be given to any director who signs a waiver of notice
either before or after the meeting. Attendance of a director at a meeting
constitutes a waiver of notice of the meeting and all objections to the time and
place of the meeting, or the manner in which it has been called or convened,
except when the director states, at the beginning of the meeting, or promptly
upon arrival at the meeting, any objection to the transaction of business
because the meeting is not lawfully called or convened. Neither the business to
be transacted at, nor the purpose of, any regular or special meeting of the
board of directors need be specified in the notice or waiver of notice of the
meeting.

         A majority of the directors present, whether or not a quorum exists,
may adjourn any meeting of the board of directors to another time and place.
Notice of any adjourned meeting shall be given to the directors who were not
present at the time of


                                        5
<PAGE>   6

the adjournment and, unless the time and place of the adjourned meeting are
announced at the time of the adjournment, to the other directors.

                               ARTICLE III. OFFICERS

         SECTION 1. OFFICERS. The officers of the Corporation shall consist of a
president, a secretary, and a treasurer, and may include one or more vice
presidents, one or more assistant secretaries, and one or more assistant
treasurers. The officers shall be elected initially by the board of directors at
the organizational meeting of board of directors and thereafter at the first
meeting of the board following the annual meeting of the shareholders in each
year. The board from time to time may elect or appoint other officers, assistant
officers, and agents, who shall have the authority and perform the duties
prescribed by the board. An elected or duly appointed officer may, in turn,
appoint one or more officers or assistant officers, unless the board of
directors disapproves or rejects the appointment. All officers shall hold office
until their successors have been appointed and have qualified or until their
earlier resignation, removal from office, or death. One person may
simultaneously hold any two or more offices. The failure to elect a president,
secretary, or treasurer shall not affect the existence of the Corporation.

         SECTION 2. PRESIDENT. The president, subject to the directions of the
board of directors, is responsible for the general and active management of the
business and affairs of the Corporation, has the power to sign certificates of
stock, bonds, deeds, and contracts for the Corporation, and shall preside at all
meetings of the shareholders.

         SECTION 3. VICE PRESIDENTS. Each vice president has the power to sign
bonds, deeds, and contracts for the Corporation and shall have the other powers
and perform the other duties prescribed by the board of directors or the
president. Unless the board otherwise provides, if the president is absent or
unable to act, the vice president who has served in that capacity for the
longest time and who is present and able to act shall perform all the duties and
may exercise any of the powers of the president. Any vice president may sign,
with the secretary or assistant secretary, certificates for stock of the
Corporation.

         SECTION 4. SECRETARY. The secretary shall have the power to sign
contracts and other instruments for the Corporation and shall (a) keep the
minutes of the proceedings of the shareholders and the board of directors in one
or more books provided for that purpose, (b) see that all notices are duly given
in accordance with the provisions of these bylaws or as required by law, (c)
maintain custody of the corporate records and the corporate seal, attest the
signatures of officers who execute documents on behalf of the Corporation,
authenticate records of the Corporation, and assure that the seal is affixed to
all documents of which execution on behalf of the Corporation under its seal is
duly authorized, (d) keep a register of the post office address of each
shareholder that shall be furnished to the secretary by the shareholder, (e)
sign with


                                        6
<PAGE>   7

the president, or a vice president, certificates for shares of stock of the
Corporation, the issuance of which have been authorized by resolution of the
board of directors, (f) have general charge of the stock transfer books of the
Corporation, and (g) in general perform all duties incident to the office of
secretary and other duties as from time to time may be prescribed by the
president or the board of directors.

         SECTION 5. TREASURER. The treasurer shall (a) have charge and custody
of and be responsible for all funds and securities of the Corporation, (b)
receive and give receipts for monies due and payable to the Corporation from any
source whatsoever, and deposit monies in the name of the Corporation in the
banks, trust companies, or other depositaries as shall be selected by the board
of directors, and (c) in general perform all the duties incident to the office
of treasurer and other duties as from time to time may be assigned to him by the
president or the board of directors. If required by the board of directors, the
treasurer shall give a bond for the faithful discharge of his duties in the sum
and with the surety or sureties that the board of directors determines.

         SECTION 6. REMOVAL OF OFFICERS. An officer or agent elected or
appointed by the board of directors or appointed by another officer may be
removed by the board whenever in its judgment the removal of the officer or
agent will serve the best interests of the Corporation. Any officer or
assistant officer, if appointed by another officer, may likewise be removed by
such officer. Removal shall be without prejudice to any contract rights of the
person removed. The appointment of any person as an officer, agent, or employee
of the Corporation does not create any contract rights. The board of directors
may fill a vacancy, however occurring, in any office.

         An officer may resign at any time by delivering notice to the
corporation. A resignation is effective when the notice is delivered unless the
notice specifies a later effective date. If a resignation is made effective at a
later date, its board of directors may fill the pending vacancy before the
effective date if the board of directors provides that the successor does not
take office until the effective date. An officer's resignation does not affect
the officer's contract rights, if any, with the corporation.

         SECTION 7. SALARIES. The board of directors from time to time shall fix
the salaries of the officers, and no officer shall be prevented from receiving
his salary merely because he is also a director of the Corporation.

                           ARTICLE IV. INDEMNIFICATION

         Any person, his heirs, or personal representative, made, or threatened
to be made, a party to any threatened, pending, or completed action or
proceeding, whether civil, criminal, administrative, or investigative, because
he is or was a director, officer, employee, or agent of this Corporation or
serves or served any other corporation or other enterprise in any capacity
at the request of this Corporation, shall be


                                        7
<PAGE>   8

indemnified by this Corporation, and this Corporation may advance his related
expenses to the full extent permitted by Florida law. In discharging his duty,
any director, officer, employee, or agent, when acting in good faith, may rely
upon information, opinions, reports, or statements, including financial
statements and other financial data, in each case prepared or presented by (1)
one or more officers or employees of the Corporation whom the director, officer,
employee, or agent reasonably believes to be reliable and competent in the
matters presented, (2) counsel, public accountants, or other persons as to
matters that the director, officer, employee, or agent believes to be within
that person's professional or expert competence, or (3) in the case of a
director, a committee of the board of directors upon which he does not serve,
duly designated according to law, as to matters within its designated authority,
if the director reasonably believes that the committee is competent. The
foregoing right of indemnification or reimbursement shall not be exclusive of
other rights to which the person, his heirs, or personal representatives may be
entitled. The Corporation may, upon the affirmative vote of a majority of its
board of directors, purchase insurance for the purpose of indemnifying these
persons. The insurance may be for the benefit of all directors, officers, or
employees.

                           ARTICLE V. STOCK CERTIFICATES

         SECTION 1. ISSUANCE. Shares may but need not be represented by
certificates. The board of directors may authorize the issuance of some or all
of the shares of the Corporation of any or all of its classes or series without
certificates. If certificates are to be issued, the share must first be fully
paid.

         SECTION 2. FORM. Certificates evidencing shares in this Corporation
shall be signed by the president or a vice president and the secretary,
assistant secretary or any other officer authorized by the board of directors,
and may be sealed with the seal of this Corporation or a facsimile of the seal.
Unless the Corporation's stock is registered pursuant to every applicable
securities law, each certificate shall bear an appropriate legend restricting
the transfer of the shares evidenced by that certificate.

         SECTION 3. LOST, STOLEN, OR DESTROYED CERTIFICATES. The Corporation may
issue a new certificate in the place of any certificate previously issued if the
shareholder of record (a) makes proof in affidavit form that the certificate has
been lost, destroyed, or wrongfully taken, (b) requests the issue of a new
certificate before the Corporation has notice that the certificate has been
acquired by the purchaser for value in good faith and without notice of any
adverse claim, (c) if requested by the Corporation, gives bond in the form that
the Corporation directs, to indemnify the Corporation, the transfer agent, and
the registrar against any claim that may be made concerning the alleged loss,

     The undersigned corporation hereby executes these Articles of Amendment
for the purpose of amending its Charter:

shareholders, the shareholders authorized an exchange of shares of common stock

stock of the Corporation, such modifications being made with the express

approval of all Shareholders of the Corporation.

meeting.

          Section 5. Notice of Meetings. Written or printed notice stating the
time and place of the meeting shall be delivered not less than ten nor more than
fifty days before the date of any shareholders' meeting, either personally or by
mail, by or at the direction of the President, the Secretary, or other person

person or by proxy, even though less than a majority, shall constitute a quorum
for the purpose of such meeting.

          The shareholders present at a duly organized meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum.

          In the absence of a quorum at the opening of a meeting of
shareholders, such meeting may be adjourned from time to time by a vote of the
majority of the shares voting on the motion to adjourn; and at any adjourned
meeting at which a quorum is present, any business may be transacted which might
have been transacted at the original meeting.

          Section 8. Proxies. Shares may be voted either in person or by one or
more agents authorized by a written proxy executed by the shareholder or by his
duly authorized attorney in fact. A proxy is not valid after the expiration of
eleven months from the date of its execution, unless the person executing it
specifies therein the length of time for which it is to continue in force, or
limits its use to a particular meeting, but no proxy shall be valid after ten
years from the date of its execution.

          Section 9. Voting of Shares. Subject to the provisions of Section 4 of
ARTICLE III, each outstanding share entitled to vote shall be entitled to one
vote on each matter submitted to a vote at a meeting of shareholders.

Section 3 of ARTICLE III, the vote of a majority of the shares voted on any
matter at a meeting of shareholders at which a quorum was initially present
shall be the act of the shareholders on that matter, unless the vote of a
greater number is required by law or by the Charter or By-Laws of this
corporation.

the persons who would be entitled to vote upon such action at a meeting, and
filed with the Secretary of the corporation to be kept in the corporate minute
book.

shareholders; and those persons who receive the highest number of votes shall be
deemed to have been elected. If any shareholder so demands, election of
directors shall be by ballot.

          Section 4. Cumulative Voting. Every shareholder entitled to vote at an
election of directors shall have the right to vote the number of shares standing
of record in his name for as many persons as there are directors to be elected
and for whose election he has a right to vote, or to cumulate his vote by giving
one candidate as many votes as the number of such directors multiplied by the
number of his shares shall equal, or by distributing such votes on the same
principle among any number of such candidates. This right of cumulative voting
shall not be exercised unless some shareholder or proxy holder announces in open
meeting, before the voting for the directors starts, his intention so to vote
cumulatively; and if such announcement is made, the chair shall declare that all
shares entitled to vote have the right to vote cumulatively and shall thereupon
grant a recess of not less than one nor more than four hours, as he shall
determine, or of such other period of time as is then unanimously agreed upon by
the shareholders entitled to vote who are present or represented at the meeting.

<PAGE>   5
          Section 5. Removal. Any director may be removed at any time with or
without cause by a vote of shareholders holding a majority of the shares
entitled to vote at an election of directors. However, unless the entire Board
is removed, an individual director may not be removed if the number of shares
voting against the removal would be sufficient to elect a director if such
shares could be voted cumulatively at an annual election. If any directors are
so removed, new directors may be elected at the same meeting.

          Section 6. Vacancies. Any vacancy occurring in the Board of Directors
may be filled by a majority of the remaining directors, though less than a
quorum, or by the sole remaining director. A director elected to fill a vacancy
shall be elected for the unexpired term of his predecessor in office. Any
directorship to be filled by reason of an increase in the authorized number of
directors shall be filled only by election at an annual meeting or at a special
meeting of shareholders called for that purpose. The shareholders may elect a
director at any time to fill any vacancy not filled by the directors.

          Section 7. Chairman of Board. There may be a Chairman of the Board of
Directors elected by the directors from their number at any meeting of the
Board. The Chairman shall preside at all meetings of the Board of Directors and
perform such other duties as may be directed by the Board.

          Section 8. Compensation. The Board of Directors may compensate
directors for their services as such and may provide for the payment of any or
all expenses incurred by directors in attending regular and special meetings of
the Board.


                                   ARTICLE IV.

          Section 1. Regular Meetings. A regular meeting of the Board of
Directors shall be held immediately after, and at the same place as, the annual
meeting of shareholders. In addition, the Board of Directors may provide, by
resolution, the time and place, either within or without the State of North
Carolina, for the holding of additional regular meetings.

          Section 2. Special Meetings. Special meetings of the Board of
Directors may be called by or at the request of the President or any three

Carolina as fixed by the person or persons calling any such meeting.

Directors may be held without notice.

<PAGE>   6

          The person or persons calling a special meeting of the Board of
Directors shall, at least two days before the meeting, give notice thereof by
any usual means of communication. Such notice need not specify the purpose for
which the meeting is called.

          Section 4. Waiver of Notice. Any director may waive notice of any
meeting. Attendance by a director at a meeting shall constitute a waiver of
notice of such meeting, except where a director attends a meeting for the
express purpose of objecting to the transaction of any business because the
meeting is not lawfully called or convened.

          Section 5. Quorum. A majority of the number of directors fixed by
these By-Laws shall constitute a quorum for the transaction of business at any
meeting of the Board of Directors.

          Section 6. Manner of Acting. Except as otherwise provided in these
By-Laws, the act of the majority of the directors present at a meeting at which
a quorum is present shall be the act of the Board of Directors.

          Section 7. Presumption of Assent. A director of the corporation who is
present at a meeting of the Board of Directors at which action on any corporate
matter is taken shall be presumed to have assented to the action taken unless
his contrary vote is recorded or his dissent is otherwise entered in the minutes
of the meeting or unless he shall file his written dissent to such action with
the person acting as the secretary of the meeting before the adjournment thereof
or shall forward such dissent by registered mail to the Secretary of the
corporation immediately after the adjournment of the meeting. Such right to
dissent shall not apply to a director who voted in favor of such action.

          Section 8. Informal Action by Directors. Action taken by a majority of
the directors without a meeting is nevertheless Board action if written consent
to the action is signed by all the directors and filed with the minutes of the
proceedings of the Board, whether done before or after the action so taken.


                                   ARTICLE V.

                               EXECUTIVE COMMITTEE

          Section 1. Creation. The Board of Directors, by resolution adopted by
a majority of the number of directors fixed by these By-Laws, may designate
three or more directors to constitute an Executive Committee, which Committee,
to the extent provided in such resolution, shall have and may exercise all of
the authority of the Board of Directors in the management of the corporation,
except that the Executive Committee shall not have any authority to alter or
amend the By-Laws.

removed at any time with or without cause by a majority of the number of
directors fixed by these By-Laws.

          Section 4. Minutes. The Executive Committee shall keep regular minutes
of its proceedings and report the same to the Board when required.

          Section 5. Responsibility of Directors. The designation of an
Executive Committee and the delegation thereto of authority shall not operate to
relieve the Board of Directors, or any member thereof, of any responsibility or
liability imposed upon it or him by law.

          If action taken by an Executive Committee is not thereafter formally
considered by the Board, a director may dissent from such action by filing his
written objection with the Secretary with reasonable promptness after learning
of such action.


                                  ARTICLE VI.

<PAGE>   8

as may from time to time be required by the Board of Directors.

                 CERTIFICATES FOR SHARES AND TRANSFER OF SHARES

          Section 1. Certificates for Shares. Certificates representing shares
of the corporation shall be issued, in such form as the Board of Directors shall
determine, to every shareholder for the fully paid shares owned by him.
Certificates shall be signed by the President or a Vice President and the
Secretary, an Assistant Secretary, Treasurer or an Assistant Treasurer. All

and address of the person to whom the shares represented thereby are issued,
with the number and class of shares and date of issue, shall be entered on the

on the stock transfer books of the corporation only upon surrender of the

for the transferred shares shall be issued.

<PAGE>   11

issuance of a new share certificate in place of a certificate claimed to have
been lost or destroyed, upon receipt of an affidavit of such fact from the
person claiming the loss or destruction. When authorizing such issuance of a new
certificate, the Board may require the claimant to give the corporation a bond
in such sum as it may direct to indemnify the corporation against loss from any
claim that may be made with respect to the certificate claimed to have been lost
or destroyed; or the Board may, by resolution, reciting that the circumstances
justify such action, authorize the issuance of the new certificate without
requiring such a bond.

          Section 4. Closing Transfer Books and Fixing Record Date. The purpose
of determining shareholders entitled to notice of or to vote at any meeting of
shareholders or any adjournment thereof, or entitled to receive payment of any
dividend, or in order to make a determination of shareholders for any other
proper purpose, the Board of Directors may provide that the stock transfer books
shall be closed for a stated period but not to exceed, in any case, fifty days.
If the stock transfer books shall be closed for the purpose of determining
shareholders entitled to notice of or to vote at a meeting of shareholders, such
books shall be closed for at least ten days immediately preceding such meeting.

          In lieu of closing the stock transfer books, the Board of Directors
may fix in advance a date as the record date for any such determination of
shareholders, such record date in any case to be not more than fifty days and,
in case of a meeting of shareholders, not less than ten days immediately
preceding the date on which the particular action, requiring such determination
of shareholders, is to be taken.

          If the stock transfer books are not closed and no record date is fixed
for the determination of shareholders entitled to notice of or to vote at a
meeting of shareholders, or shareholders entitled to receive payment of a
dividend, the date on which notice of the meeting is mailed or the date on which
the resolution of the Board of Directors declaring such dividend is adopted, as
the case may be, shall be the record date for such determination of
shareholders.

          When a determination of shareholders entitled to vote at any meeting
of shareholders has been made as provided in this section, such determination
shall apply to any adjournment thereof except where the determination has been
made through the closing of the stock transfer books and the stated period of
closing has expired.

<PAGE>   12

          Section 5. Holder of Record. The corporation may treat as absolute
owner of shares the person in whose name the shares stand of record on its books
just as if that person had full competency, capacity and authority to exercise
all rights of ownership irrespective of any knowledge or notice to the contrary
or any description indicating a representative, pledge or other fiduciary
relation or any reference to any other instrument or to the rights of any other
person appearing upon its record or upon the share certificate except that any
person furnishing to the corporation proof of his appointment as a fiduciary
shall be treated as if he were a holder of record of its shares.

          Section 6. Treasury Shares. Treasury shares of the corporation shall
consist of such shares as have been issued and thereafter acquired but not
cancelled by the corporation. Treasury shares shall not carry voting or dividend
rights.


                                   ARTICLE IX.

                               GENERAL PROVISIONS

          Section 1. Dividends. The Board of Directors may from time to time
declare, and the corporation may pay, dividends on its outstanding shares in
cash, property, or its own shares, pursuant to law and subject to the provisions
of its Charter.

          Section 2. Seal. The corporate seal of the corporation shall consist

the center of which is inscribed SEAL; and such seal, as impressed on the margin
hereof, is hereby adopted as the corporate seal of the corporation.

          Section 3. Waiver of Notice. Whenever any notice is required to be
given to any shareholder or director by law or by the Charter or By-Laws of the
corporation, a waiver thereof in writing signed by the person or persons
entitled to such notice, whether before or after the time stated therein, shall
be equivalent to the giving of such notice.

          Section 4. Fiscal Year. The fiscal year of the corporation shall be
fixed by the Board of Directors.

          Section 5. Amendments. Except as otherwise provided herein, these
By-Laws may be amended or repealed and new By-Laws may be adopted by the
affirmative vote of a majority of the Directors then holding office at any
regular or special meeting of the Board of Directors.

<PAGE>   13

          The Board of Directors shall have no power to adopt a By-Law: (1)
requiring more than a majority of the voting shares for a quorum at a meeting of
shareholders or more than a majority of the votes cast to constitute action by
the shareholders, except where higher percentages are required by law; (2)
providing for the management of the corporation otherwise than by the Board of
Directors or its Executive Committee; (3) increasing or decreasing the number of
directors; (4) classifying and staggering the election of directors.

          Any By-Law adopted or amended by the shareholders shall not be altered
or repealed by the Board of Directors or Executive Committee.

                                   ARTICLE II

                  Section 2.01. MANNER OF GIVING NOTICE. Whenever written notice
is required to be given to any person under the provisions of the Business

Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the board of directors need be specified in a notice of a
meeting.

                  Section 2.03. NOTICE OF MEETINGS OF SHAREHOLDERS.

                  (a) General rule. Written notice of every meeting of the
shareholders shall be given by, or at the direction of, the secretary or other
authorized person to each shareholder of record entitled to vote at the meeting
at least:

                           (1) ten days prior to the day named for a meeting
         called to consider a fundamental change under 15 Pa.C.S. Chapter 19
         regarding amendments of articles of incorporation, mergers,
         consolidations, share exchanges, sale of assets, divisions,
         conversions, liquidations and dissolution; or

                           (2) five days prior to the day named for the meeting
         in any other case.

If the secretary or other authorized person neglects or refuses to give notice
of a meeting, the person or persons calling the meeting may do so. In the case
of a special meeting of shareholders, the notice shall specify the general
nature or the business to be transacted.


                  (b) Notice of action by shareholders on bylaws. In the case of
a meeting of shareholders that has as its purpose or one of its purposes, action
on the bylaws, written notice shall be given to each shareholder that the
purpose, or one of the purposes, of the meeting is to consider the adoption,
amendment, or repeal of the bylaws. There shall be included in, or enclosed
with, the notice a copy of the proposed amendment or a summary of the changes to
be effected thereby.

                  (c) Adjourned shareholder meetings. When a meeting of
shareholders is adjourned, it shall not be necessary to give any notice of the
adjourned meeting or of the business to be transacted at an adjourned meeting,

                  Section 2.04. WAIVER OF NOTICE.

                  (a) Written waiver. Whenever any written notice is required to
be given under the provisions of the Business Corporation Law, the articles of
incorporation or these bylaws, a waiver thereof in writing, signed by the person
or persons entitled to the notice, whether before or after the time stated
therein, shall be deemed equivalent to the giving of the notice. Except as
otherwise required by this subsection, neither the business to be transacted at,
nor the purpose of, a meeting need be specified in the waiver of notice of the
meeting. In the case of a special meeting of shareholders, the waiver of notice
shall specify the general nature of the business to be transacted.

                  (b) Waiver by attendance. Attendance of a person at any
meeting shall constitute a waiver of notice of the meeting except where a person
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting was not lawfully
called or convened.


                  Section 2.05. MODIFICATION OF PROPOSAL CONTAINED IN NOTICE.
Whenever the language of a proposed resolution is included in a written notice
of a meeting required to be given under the provisions of the Business
Corporation Law, the articles of incorporation or these bylaws, the meeting
considering the resolution may without further notice adopt it with such
clarifying or other amendments as do not enlarge its original purpose.

                  Section 2.06. EXCEPTION TO REQUIREMENT OF NOTICE.

                  (a) General rule. Whenever any notice or communication is
required to be given to any person under the provisions of the Business
Corporation Law, the articles of incorporation, or these bylaws or by the terms
of any agreement or other instrument or as a condition precedent to taking any
corporate action, and communication with that person is then unlawful, the
giving of the notice or communication to that person shall not be required and
there shall be no duty to apply for a license or other permission to do so.

                  (b) Shareholders without forwarding addresses. Notice or other
communications shall not be required to be sent to any shareholder with whom the
corporation has been unable to communicate for more than 24 consecutive months
because communications to the shareholder are returned unclaimed or the
shareholder has otherwise failed to provide the corporation with a current
address. Whenever the shareholder provides the corporation with a current
address, the corporation shall


                                       -3-

<PAGE>   8


commence sending notices and other communications to the shareholder in the same
manner as to other shareholders.

                  Section 2.07. USE OF CONFERENCE TELEPHONE AND SIMILAR
EQUIPMENT. One or more persons may participate in a meeting of the board of
directors or of the shareholders of the corporation by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other. Participation a meeting
pursuant to this section shall constitute presence in person at the meeting.

                                   ARTICLE III

                                  SHAREHOLDERS

                  Section 3.01. THIS SECTION INTENTIONALLY LEFT BLANK.

                  Section 3.02. PLACE OF MEETING. Meetings of the shareholders
may be held either within or without the Commonwealth of Pennsylvania. All
meetings of the shareholders of the corporation shall be held at the registered
office of the corporation unless another place is designated by the board of
directors in the notice of a meeting.

                  Section 3.03. MEETINGS.

                  (a) ANNUAL MEETING. At least one meeting of the shareholders
shall be held in each calendar year for the purpose of electing a board of
directors and transacting such other business as may properly be brought before
the meeting. There may also be such other regularly scheduled meetings as the
board of directors may from time to time designate. Both the annual and other
regular meetings shall be held on such date and at such time as the board of
directors shall designate. If the annual or other regular meeting is not called
and held within six months after the designated time, any shareholder may call
the meeting at any time thereafter.

                  (b) SPECIAL MEETINGS.

                           (1) Call of special meetings. Special meetings of the
         shareholders may be called at any time:

                                    (i) by the board of directors; or

                                    (ii) unless otherwise provided in the
                  articles of incorporation, by shareholders entitles cast at
                  least 20% of the votes that all shareholders are entitled to
                  cast at the particular meeting.

<PAGE>   9

                           (2) Fixing of time for meeting. At any time, upon
         written request of any person who has called a special meeting, it
         shall be the duty of the secretary to fix the time of the meeting which
         shall be held not more than 60 days after the receipt of the request.
         If the secretary neglects or refuses to fix the time of the meeting,
         the person or persons calling the meeting may do so.

                  Section 3.04. QUORUM AND ADJOURNMENT.

                  (a) General rule. A meeting of shareholders of the corporation
duly called shall not be organized for the transaction of business unless a
quorum is present. The presence of shareholders entitled to cast at least a
majority of the votes that all shareholders are entitled to cast on a particular
matter to be acted upon at the meeting shall constitute a quorum for the
purposes of consideration and action on the matter. Shares of the corporation
owned, directly or indirectly, by it and controlled, directly or indirectly, by
the board of directors of this corporation, as such, shall not be counted in
determining the total number of outstanding shares for quorum purposes at any
given time.

                  (b) Withdrawal of a quorum. The shareholders present at a duly
organized meeting can continue to do business until adjournment notwithstanding
the withdrawal of enough shareholders to leave less than a quorum.

                  (c) Adjournment for lack of quorum. If a meeting cannot be
organized because a quorum has not attended, those present may, except as
provided in the Business Corporation Law, adjourn the meeting to such time and
place as they may determine.

                  (d) Adjournments generally. Any meeting at which directors are
to be elected shall be adjourned only from day to day, or for such longer
periods not exceeding 15 days each as the shareholders present and entitled to
vote shall direct, until the directors have been elected. Any other regular or
special meeting may be adjourned for such period as the shareholders present and
entitled to vote shall direct.

                  (e) Electing directors at adjourned meeting. Those
shareholders entitled to vote who attend a meeting called for the election of

quorum, although less than a quorum as fixed in this section or in these bylaws,

quorum for the purpose of acting upon the matter.

                  Section 3.05. ACTION BY SHAREHOLDERS.

                  proposed transaction; or

                           (2) in which the consideration to be received by the

          owned by the interested shareholder is not less than the highest
          amount paid by the interested shareholder in acquiring shares of the
          same class.

                  (d) Additional approvals. The approvals required by this

                  Section 3.08. VOTING AND OTHER ACTION BY PROXY.

         of shareholders or to express consent or dissent to corporate action in
         writing without a meeting may authorize another person to act for him
         by proxy.

                           (2) The presence of, vote by, or other action at a
          meeting of shareholders by, or the expression of consent or dissent to

<PAGE>   12


effective until written notice thereof has been given to the secretary of the
corporation. An unrevoked proxy shall not be valid after three years from the
date of its execution unless a longer time is expressly provided therein. A
proxy shall not be revoked by the death or incapacity of the maker unless,
before the vote is counted or the authority is exercised, written notice of the
death or incapacity is given to the secretary of the corporation.

                  Section 3.09. NO VOTING BY THIS CORPORATION. Shares of this
corporation owned, directly or indirectly, by it and controlled, directly or
indirectly, by the board of directors of this corporation, as such, shall not be

                  Section 3.10. DETERMINATION OF SHAREHOLDERS OF RECORD.

                           (a) Fixing record date. The board of directors may
         fix a time prior to the date of any meeting of shareholders as a
         record date for the determination of the shareholders entitled to
         notice of, or to vote at, the meeting, which time, except in the case
         of an adjourned meeting, shall be not more than 90 days prior to the
         date of the meeting of shareholders. Only shareholders of record on the
         date fixed shall be so entitled notwithstanding any transfer of shares
         on the books of the corporation after any record date fixed as provided
         in this subsection. The board of directors may similarly fix a record
         date for the determination of shareholders of record for any other
         purpose. When a determination of shareholders of record has been made
         as provided in this section for purposes of a meeting, the
         determination shall apply to any adjournment thereof unless the board
         fixes a new record date for the adjourned meeting.

                           (b) Determination when a record date is not fixed. If
         a record date is not fixed:

                                    (1) The record date for determining
                  shareholders entitled to notice of or to vote at a meeting of
                  shareholders shall be at the close of business on the date
                  next preceding the day on which notice is given or, if notice
                  is waived, at the close of business on the day immediately
                  preceding the day on which the meeting is held.

                                    (2) The record date for determining
                  shareholders entitled to express consent or dissent to
                  corporate action in writing without a meeting, when prior
                  action by the board of directors is not necessary shall be the
                  close of business on the day on which the first written
                  consent or dissent is filed with the secretary of the
                  corporation.

<PAGE>   13


                                     (3) The record date for determining
                  shareholders for any other purpose shall be at the close of
                  business on the day on which the board of directors adopts the
                  resolution relating thereto.

                  Section 3.11. VOTING LISTS.

                  (a) General rule. The officer or agent having charge of the
transfer books for shares of the corporation shall make a complete list of the
shareholders entitled to vote at any meeting of shareholders, arranged in
alphabetical order, with the address of and the number of shares held by each.
The list shall be produced and kept open at the time and place of the meeting
and shall be subject to the inspection of any shareholder during the whole time
of the meeting for the purposes thereof.

                  (b) Effect of list. Failure to comply with the requirements of
this section shall not affect the validity of any action taken at a meeting
prior to a demand at the meeting by any shareholder entitled to vote thereat to
examine the list. The original share register or transfer book, or a duplicate
thereof kept in this Commonwealth, shall be prima facie evidence as to who are
the shareholders entitled to examine the list or share register or transfer book
or to vote at any meeting of shareholders.

                  Section 3.12. JUDGES OF ELECTION.

                  (a) Appointment. In advance of any meeting of shareholders of
the corporation, the board of directors may appoint judges of election, who need
not be shareholders, to act at the meeting or any adjournment thereof. If judges
of election are not so appointed, the presiding officer of the meeting may, and
on the request of any shareholder shall, appoint judges of election at the
meeting. The number of judges shall be one or three. A person who is a candidate
for office to be filled at the meeting shall not act as a judge.

                  (b) Vancancies. In case any person appointed as a judge fails
to appear or fails or refuses to act, the vacancy be filled by appointment made
by the board of directors in advance of the convening of the meeting or at the
meeting by the presiding officer thereof.

                  (c) Duties. The judges of election shall (1) determine the
number of shares outstanding and the voting power of each, the shares
represented at the meeting, the existence of a quorum, the authenticity,
validity and effect of proxies, (2) receive votes or ballots, (3) hear and
determine all challenges and questions in any way arising in connection with the
right to vote, (4) count and tabulate all votes, (5) determine the results and
(6) do such acts as may be proper to conduct the election


                                      -9-

<PAGE>   14


vote with fairness to all shareholders. The judges of election shall perform
their duties impartially, in good faith, to the best of their ability and as
expeditiously as is practical. If there are three judges of election, the
decision, act or certificate of a majority shall be effective in all respects as
the decision, act or certificate of all.

                  (d) Report. On request of the presiding officer of the
meeting, or of any shareholder, the judges of election shall make a report in
writing of any challenge or question or matter determined by them, and execute a
certificate of any fact found by them. Any report or certificate made by them
shall be prima facie evidence of the facts stated therein.

                  Section 3.13. CONSENT OF SHAREHOLDERS IN LIEU OF MEETING.

                  (a) Unanimous written consent. Any action required or
permitted to be taken at a meeting of the shareholders or of a class of
shareholders may be taken without a meeting if, prior or subsequent to the
action, a consent or consents thereto by all of the shareholders who would be
entitled to vote at a meeting for such purpose shall be filed with the secretary
of the corporation.

                  (b) Partial written consent. Any action required or permitted
to be taken at a meeting of the shareholders or of a class of shareholders may
be taken without a meeting upon the written consent of shareholders who would
have been entitled to cast the minimum number of votes that would be necessary
to authorize the action at a meeting at which all shareholders entitled to vote
thereon were present and voting. The consents shall be filed with the secretary
of the corporation. The action shall not become effective until after at least
ten days written notice of the action has been given to each shareholder
entitled to vote thereon who has not consented thereto.

                                   ARTICLE IV

                               BOARD OF DIRECTORS

                  Section 4.01. POWERS; PERSONAL LIABILITY.

                  (a) General rule. Unless otherwise provided by statute all
powers vested by law in the corporation shall be exercised by or under the
authority of, and the business and affairs of the corporation shall be managed
under the direction of, the board of directors.

                  (b) Standard of care; justifiable reliance. A director shall
stand in a fiduciary relation to the corporation and shall perform his or her
duties as a director, including



                                      -10-

<PAGE>   15


duties as a member of any committee of the board upon which the director may
serve, in good faith, in a manner the director reasonably believes to be in the
best interests of the corporation and with such care, including reasonable
inquiry, skill and diligence, as a person of ordinary prudence would use under
similar circumstances. In performing his or her duties, a director shall be
entitled to rely in good faith on information, opinions, reports or statements,
including financial statements and other financial data, in each case prepared
or presented by any of the following:

                           (1) One or more officers or employees of the
         corporation whom the director reasonably believes to be reliable and
         competent in the matters presented.

                           (2) Counsel, public accountants or other persons as
         to matters which the director reasonably believes to be within the
         professional or expert competence of such person.

                           (3) A committee of the board upon which the director
         does not serve, duly designated in accordance with law, as to matters
         within its designated authority, which committee the director
         reasonably believes to merit confidence.

A director shall not be considered to be acting in good faith if the director
has knowledge concerning the matter in question that would cause his or her
reliance to be unwarranted.

                  (c) Consideration of factors. In discharging the duties of
their respective positions, the board of directors, committees of the board and
individual directors may, in considering the best interests of the corporation,
consider the effects of any action upon employees, upon suppliers and customers
of the corporation and upon communities in which offices or other establishments
of the corporation are located, and all other pertinent factors. The
consideration of those factors shall not constitute a violation of subsection
(b).

                  (d) Presumption. Absent breach of fiduciary duty, lack of good
faith or self-dealing, actions taken as a director or any failure to take any
action shall be presumed to be in the best interests of the corporation.

                  (e) Personal liability of directors.

                           (1) A director shall not be personally liable, as
         such, for monetary damages for any action taken, or any failure to take
         any action, unless:


                                      -11-


<PAGE>   16


                                    (i) the director has breached or failed to
                  perform the duties of his or her office under this section;
                  and


                                    (ii) the breach or failure to perform
                  constitutes self-dealing, willful misconduct or recklessness,

                           (2) The provisions of paragraph (1) shall not apply
         to:

                                    (i) the responsibility or liability of a
                  director pursuant to any criminal statute; or

                                    (ii) the liability of a director for the
                  payment of taxes pursuant to local, State or Federal law.

                  (f) Notation of dissent. A director who is present at a
meeting of the board of directors, or of a committee of the board, at which
action on any corporate matter is taken shall be presumed to have assented to
the action taken unless his or her dissent is entered in the minutes of the
meeting or unless the director files a written dissent to the action with the
secretary of the meeting before the adjournment thereof or transmits the dissent
in writing to the secretary of the corporation immediately after the adjournment
of the meeting. The right to dissent shall not apply to a director who voted in
favor of the action. Nothing in this section shall bar a director from asserting
that minutes of the meeting incorrectly omitted his or her dissent if, promptly
upon receipt of a copy of such minutes, the director notifies the secretary in
writing of the asserted omission or inaccuracy.

                  Section 4.02. QUALIFICATION AND SELECTION OF DIRECTORS.

                  (a) Qualifications. Each director of the corporation shall be
a natural person of full age and, unless otherwise required by law, need not be
a resident of the Commonwealth of Pennsylvania.

                  (b) Election of directors. Except as otherwise provided in
these bylaws, directors of the corporation shall be elected by the shareholders.
In elections for directors, voting need not be by ballot, except upon demand
made by a shareholder entitled to vote at the election and before the voting
begins. The candidates receiving the highest number of votes from each class or
group of classes, if any, entitled to elect directors separately up to the
number of directors to be elected by the class or group of classes shall be
elected. If at any meeting of shareholders, directors of more than one class are
to be elected, each class of directors shall be elected in a separate election.

                  (a) Number. The board of directors shall consist of one or
more members. The number of directors shall be fixed from time to time by the
vote of a majority of the whole board of directors or of the shareholders.

                  (b) Term of office. Each director shall hold office for a term
of one year and until his or her successor has been selected and qualified or
until his or her earlier death, resignation or removal. A decrease in the number
of directors shall not have the effect of shortening the term of any incumbent
director.

                  (c) Resignation. Any director may resign at any time upon
written notice to the corporation. The resignation shall be effective upon
receipt thereof by the corporation or at such subsequent time as shall be
specified in the notice of resignation.

                  Section 4.04. VACANCIES.

                  (a) General rule. Vacancies in the board of directors,
including vacancies resulting from an increase in the number of directors, may
be filled by a majority vote of the remaining members of the board though less
than a quorum, or by a sole remaining director, and each person so selected
shall be a director to serve for the balance of the unexpired term, and until a
successor has been selected and qualified or until his or her earlier death;
resignation or removal.

                  (b) Action by resigned directors. When one or more directors
resign from the board effective at a future date, the directors then in office,
including those who have so resigned, shall have power by the applicable vote to
fill the vacancies, the vote thereon to take effect when the resignations become
effective.

                  Section 4.05. REMOVAL OF DIRECTORS.

                  (a) Removal by the shareholders. The entire board of
directors, or any class of the board, or any individual director may be removed
from office without assigning any cause by the vote of shareholders, or of the
holders of a class or series of shares, entitled to elect directors, or the
class of directors. In case the board or a class of the board or any one or more
directors are so removed, new directors may be elected at the same meeting. The
board of directors may be removed at any time with or without cause by the
unanimous vote or consent of shareholders entitled to vote thereon.

<PAGE>   18


                  (b) Removal by the board. The board of directors may declare
vacant the office of a director who has been judicially declared of unsound mind
or who has been convicted of an offense punishable by imprisonment for a term of
more than one year or if, within 60 days after notice of his or her selection,
the director does not accept the office either in writing or by attending a
meeting of the board of directors and fulfill such other requirements of
qualification as these bylaws may specify.

                  (c) Removal of directors elected by cumulative voting. If the
shareholders are entitled to vote cumulatively in electing a board or a class of
the board, an individual director shall not be removed (unless the entire board
or class of the board is removed) from the board if sufficient votes are cast
against the resolution for his or her removal which, if cumulatively voted at an
annual or other regular election of directors, would be sufficient to elect the
director to the board or to the class.

                  Section 4.06. PLACE OF MEETINGS. Meetings of the board of
directors may be held at such place within or without the Commonwealth of

the officer or committee to which the power to elect such officers or to retain

corporation to the full extent of such disallowance. It shall be the duty of the
directors, as a board, to enforce payment of each such amount disallowed. In
lieu of payment by the officer or employee, subject to the determination of the
directors, proportionate amounts may be withheld from future compensation
payments until the amount owed to the corporation has been recovered.

                                   ARTICLE VI

the corporation shall be in such form as approved by the board of directors, and

ceased to be such officer because of death, resignation or otherwise, before
the certificate is issued, it may be issued with the same effect as if the
officer had not  ceased to be such at the date of its

                                      -19-

issue. The provisions of this Section 6.02 shall be subject to any inconsistent

or registrar.

                  Section 6.03. TRANSFER. Transfers of shares shall be made on
the share register or transfer books of the corporation upon surrender of the

or destruction of the certificate, upon satisfactory proof of such loss or
destruction and, if the board of directors shall so determine, the deposit of a
bond in such form and in such sum, and with such surety or sureties, as it may

                                   ARTICLE VII

                   INDEMNIFICATION OF DIRECTORS, OFFICERS AND
                        OTHER AUTHORIZED REPRESENTATIVES

                  Section 7.01. SCOPE OF INDEMNIFICATION.

                  (a) General Rule. The corporation shall indemnify an
indemnified representative against any liability incurred in connection with any
proceeding in which the indemnified representative may be involved as a party or
otherwise by reason of the fact that such person is or was serving in an
indemnified capacity, 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:

                                      -20-



<PAGE>   25

                           (1) where such indemnification is expressly
         prohibited by applicable law;

                           (2) where the conduct of the indemnified
         representative has been finally determined pursuant to Section 7.06 or
         otherwise:

                                    (i) to constitute willful misconduct or
                  recklessness within the meaning of 15 Pa. C.S. 513(b) and
                  1746(b) and 42 Pa.C.S. 8365(b) or any superseding provision
                  of law sufficient in the circumstances to bar indemnification
                  against liabilities arising from the conduct; or

                                    (ii) to be based 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 pursuant to Section 7.06 to
         be otherwise unlawful.

                    (b) Partial payment. If an indemnified representative is
entitled to indemnification in respect of a portion, but not all, of any
liabilities to which such person may be subject, the corporation shall indemnify
such indemnified representative to the maximum extent for such portion of the
liabilities.

                    (c) Presumption. The termination of a proceeding by
judgment, order, settlement or conviction or upon a plea of nolo contendere or
its equivalent shall not of itself create a presumption that the indemnified
representative is not entitled to indemnification.

                  (d) Definitions. For purposes of this Article:

                           (1) "indemnified capacity" means any and all past,
         present and future service by an indemnified representative in one or
         more capacities as a director, officer, employee or agent of the
         corporation, or, at the request of the corporation, as a director,
         officer, employee, agent, fiduciary or trustee of another corporation,
         partnership, joint venture, trust, employee benefit plan or other
         entity or enterprise;

                           (2) "indemnified representative" means any and all
         directors and officers of the corporation and any other person
         designated as an indemnified representative by the board of directors
         of the corporation (which may, but may not, include any person serving
         at the request of the corporation, as a director, officer, employee,
         agent,

                                      -21-


<PAGE>   26


         fiduciary or trustee of any other corporation, partnership, joint
         venture, trust, employee benefit plan or other entity or enterprise);

                           (3) "liability" means 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); and

                           (4) "proceeding" means any threatened, pending or
         completed action, suit, appeal or other proceeding of any nature,
         whether civil, criminal, administrative or investigative, whether
         formal or informal, and whether brought by or in the right of the
         corporation, a class of its security holders or otherwise.

                  Section 7.02. PROCEEDINGS INITIATED BY INDEMNIFIED
REPRESENTATIVES. Notwithstanding any other provision of this Article, the
corporation shall not indemnify under this Article an indemnified representative
for any liability incurred in a proceeding initiated (which shall not be deemed
to include counter-claims or affirmative defenses) or participated in as an
intervenor or amicus curiae by the person seeking indemnification unless such
initiation of or participation in the proceeding is authorized, either before or
after its commencement, by the affirmative vote of a majority of the directors
in office. This section does not apply to a reimbursement of expenses incurred
in successfully prosecuting or defending an arbitration under Section 7.06 or
otherwise successfully prosecuting or defending the rights of an indemnified
representative granted by or pursuant to this Article.

                  Section 7.03. ADVANCING EXPENSES. The corporation shall pay
the expenses (including attorneys' fees and disbursements) incurred in good
faith by an indemnified representative in advance of the final disposition of a
proceeding described in Section 7.01 or in advance of the initiation of or
participation in a proceeding which is authorized pursuant to Section 7.02 upon
receipt of an undertaking by or on behalf of the indemnified representative to
repay the amount if it is ultimately determined pursuant to Section 7.06, or
otherwise, that such person is not entitled to be indemnified by the corporation
pursuant to this Article. The financial ability of an indemnified representative
to repay an advance shall not be a prerequisite to the making of such advance.

                  Section 7.04. SECURING OF INDEMNIFICATION OBLIGATIONS. To
further effect, satisfy or secure the indemnification obligations provided
herein or otherwise, the corporation may maintain insurance, obtain a letter of
credit, act as


                                      -22-


<PAGE>   27


self-insurer, create a reserve, trust, escrow, cash collateral or other fund or
account, enter into indemnification agreements, pledge or grant a security
interest in any assets or properties of the corporation, or use any other
mechanism or arrangement whatsoever in such amounts, at such costs, and upon
such other terms and conditions as the board of directors shall deem
appropriate. Absent fraud, the determination of the board of directors with
respect to such amounts, costs, terms and conditions shall be conclusive against
all security holders, officers and directors and shall not be subject to
voidability.

                  Section 7.05. PAYMENT OF INDEMNIFICATION. An indemnified
representative shall be entitled to indemnification within 30 days after a
written request for indemnification has been delivered to the secretary of the
corporation.

                  Section 7.06. ARBITRATION.

                  (a) General rule. Any dispute related to the right to
indemnification, contribution or advancement of expenses as provided under this
Article, except with respect to indemnification for liabilities arising under
the Securities Act of 1933 that the corporation has undertaken to submit to a
court for adjudication, shall be decided only by arbitration in the metropolitan
area in which the principal executive offices of the corporation are located at
the time, in accordance with the commercial arbitration rules then in effect of
the American Arbitration Association, before a panel of three arbitrators, one
of whom shall be selected by the corporation, the second of whom shall be
selected by the indemnified representative and third of whom shall be selected
by the other two arbitrators. In the absence of the American Arbitration
Association, or if for any reason arbitration under the arbitration rules of the
American Arbitration Association cannot be initiated, or if one of the parties
fails or refuses to select an arbitrator or if the arbitrators selected by the
corporation and the indemnified representative cannot agree on the selection of
the third arbitrator within 30 days after such time as the corporation and the
indemnified representative have each been notified of the selection of the
other's arbitrator, the necessary arbitrator or arbitrators shall be selected by
the presiding judge of the court of general jurisdiction in such metropolitan
area.

                  (b) Burden of proof. The party or parties challenging the
right of an indemnified representative to the benefits of this Article shall
have the burden of proof.

                  (c) Expenses. The corporation shall reimburse an indemnified
representative for the expenses (including attorneys fees and disbursements)
incurred successfully prosecuting or defending such arbitration.


                                      -23-


<PAGE>   28

                  (d) Effect. Any award entered by the arbitrators shall be
final, binding and nonappealable and judgment may be entered thereon by any
party in accordance with applicable law in any court of competent jurisdiction,
except that the corporation shall be entitled to interpose as a defense in any
such judicial enforcement proceeding any prior final judicial determination
adverse to the indemnified representative under Section 7.01 (a) (2) in a
proceeding not directly involving indemnification under this Article. This
arbitration provision shall be specifically enforceable.

                  Section 7.07. CONTRIBUTION. If the indemnification provided
for in this Article or otherwise is unavailable for any reason in respect of any
liability or portion thereof, the corporation shall contribute to the
liabilities to which the indemnified representative may be subject in such
proportion as is appropriate to reflect the intent of this Article or otherwise

                  Section 7.08. MANDATORY INDEMNIFICATION OF DIRECTORS,
OFFICERS, ETC. To the extent that an authorized representative of the
corporation has been successful on the merits or otherwise in defense of any
action or proceeding referred to in 15 Pa.C.S. 1741 or 1742 or in defense of
any claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees and disbursements) actually and reasonably
incurred by such person in connection therewith.

                  Section 7.09. CONTRACT RIGHTS; AMENDMENT OR REPEAL. All rights
under this Article shall be deemed a contract between the corporation and the
indemnified representative pursuant to which the corporation and each
indemnified representative intend to be legally bound. Any repeal, amendment or
modification hereof shall be prospective only and shall not affect any rights or
obligations then existing.


                  Section 7.10. SCOPE OF ARTICLE. The rights granted by this
Article shall not be deemed exclusive of any other rights to which those seeking
indemnification, contribution or advancement of expenses may be entitled under
any statute, agreement, vote of shareholders or disinterested directors or
otherwise both as to action in an indemnified capacity and as to action in any
other capacity. The indemnification, contribution and advancement of expenses
provided by or granted pursuant to this Article shall continue as to a person
who has ceased to be an indemnified representative in respect of matters arising
prior to such time, and shall inure to the benefit of the heirs, executors,
administrators and personal representatives of such a person.

                  Section 7.11. RELIANCE OF PROVISIONS. Each person who shall
act as an indemnified representative of the corporation


                                      -24-

<PAGE>   29



shall be deemed to be doing so in reliance upon the rights provided in this
Article.

                  Section 7.12. INTERPRETATION. The provisions of this Article
are intended to constitute bylaws authorized by 15 Pa.C.S. 513 and 1746 and 42
Pa.C.S. 8365.

                                  ARTICLE VIII

                                  MISCELLANEOUS

may from time to time designate.

                  Section 8.03. CONTRACTS.

                  (a) General rule. Excepts as otherwise provided in the
Business Corporation Law in the case of transactions that require action by the
shareholders, the board of directors may authorize any officer or agent to enter

financial or other interest, shall not be void or voidable solely for that
reason, or solely because the director or officer is present at or participates
in the meeting of the board of directors that authorizes the contract or
transaction, or solely because his, her or their votes are counted for that
purpose, if:

                           (1) the material facts as to the relationship or
         interest and as to the contract or transaction are disclosed or are
         known to the board of directors and the board authorizes the contract
         or transaction by the affirmative votes of a majority of the

                           (2) the material facts as to his or her relationship
         or interest and as to the contract or transaction are disclosed or are
         known to the shareholders entitled to vote thereon and the contract or
         transaction is specifically approved in good faith by vote of those
         shareholders; or

                           (3) the contract or transaction is fair as to the
         corporation as of the time it is authorized, approved or ratified by
         the board of directors or the shareholders.

one or more officers or employees as the board of directors shall from time to
time determine.

accurate books and records of account, minutes of the proceedings of the

or by agent or attorney, during the usual hours for business for any proper
purpose, the share register, books and records of account, and records of the
proceedings of the incorporators, shareholders and directors and to make copies
or extracts therefrom. A proper purpose shall mean a purpose reasonably related
to the interest of the person as a shareholder. In every instance where an
attorney or other agent is the person who seeks the right of inspection, the
demand shall be accompanied by a verified power of attorney or other writing
that authorizes the attorney or other agent to so act on behalf of the
shareholder. The demand shall be directed to the corporation at its registered
office in the Commonwealth of Pennsylvania or at its principal place of business
wherever situated.

                  Section 8.07. FINANCIAL REPORTS. Unless otherwise agreed

generally accepted accounting principals, if the corporation prepares financial
statements for the fiscal year on that basis for any purpose, and may be
consolidated statements of the corporation and one or more of its subsidiaries.
The financial statements shall be mailed by the corporation to each of its
shareholders entitled thereto within 120 days after the close of each fiscal
year and, after the mailing and upon written request, shall be mailed by the
corporation to any shareholder or beneficial owner entitled thereto to whom a
copy of the most recent annual financial statements has not previously been
mailed. Statements that are audited or reviewed by a public accountant shall be
accompanied by the report of the accountant. In other cases, each copy shall be
accompanied by a statement of the person in charge of the financial records of
the corporation:

                           (1) Stating his or her reasonable belief as to
         whether or not the financial statements were prepared in accordance
         with generally accepted accounting principles and, if not, describing
         the basis of presentation.

                           (2) Describing any material respects in which the
         financial statements were not prepared on a basis consistent with those
         prepared for the previous year.

                  Section 8.08. AMENDMENT OF BYLAWS. These bylaws may be amended
or repealed, or new bylaws may be adopted, either (i) by vote of the
shareholders at any duly organized annual or special meeting of shareholders, or
(ii) with respect to those matters that are not by statute committed expressly
to the

                                      -27-

office.

                            ARTICLE II. SHAREHOLDERS

     2.01. Annual Meeting. The annual meeting of the shareholders shall be held
at the date and hour in each year set forth in Section 0.01, or at such other
time and date within thirty days before or after said date as may be fixed by or
under the authority of the Board of Directors, for the purpose of electing
directors and for the transaction of such other business as may come before the
meeting. If the day fixed for the annual meeting shall be a legal holiday in the
State of Kansas, such meeting shall be held on the next succeeding business day.
If the election of directors shall not be held on the day designated herein, or
fixed as herein provided, for any annual meeting of the shareholders, or at any
adjournment thereof, the Board of Directors shall cause the election to be held
at a special meeting of the shareholders as soon thereafter as conveniently may
be.

     2.02. Special Meeting. Special meetings of the shareholders, for any
purpose or purposes, unless otherwise prescribed by statute, may be called by
the President or the Board of Directors or by the person designated in the
written request of the holders of not less than one-tenth of all shares of the
corporation entitled to vote at the meeting.

     2.03. Place of Meeting. The Board of Directors may designate any place,
either within or without the State of Kansas, as the place of meeting for any
annual meeting or for any special meeting called by the Board of Directors. A
waiver of notice signed by all shareholders entitled to vote at a meeting may

<PAGE>   3


without the State of Kansas, as the place for the holding of such meeting. If no
designation is made, or if a special meeting be otherwise called, the place of
meeting shall be the principal business office of the corporation in the State
of Kansas or such other suitable place in the county of such principal office as
may be designated by the person calling such meeting, but any meeting may be
adjourned to reconvene at any place designated by vote of a majority of the
shares represented thereat.

     2.04. Notice of Meeting. Written notice stating the place, day and hour of
the meeting and, in case of a special meeting, the purpose or purposes for which
the meeting is called, shall be delivered not less than the number of days set

of incorporation) nor more than fifty days before the date of the meeting,
either personally or by mail, by or at the direction of the President, or the
Secretary, or other officer or persons calling the meeting, to each shareholder
of record entitled to vote at such meeting. If mailed, such notice shall be
deemed to be delivered when deposited in the United States mail, addressed to
the shareholder at his address as it appears on the stock record books of the
corporation, with postage thereon prepaid.

     2.05. Closing of Transfer Books or Fixing of Record Date. For the purpose
of determining shareholders entitled to notice of or to vote at any meeting of
shareholders or any adjournment thereof, or shareholders entitled to receive
payment of any dividend, or in order to make a determination of shareholders for
any other proper purpose, the Board of Directors may provide that the stock
transfer books shall be closed for a stated period but not to exceed, in any
case, fifty days. If the stock transfer books shall be closed for the purpose of
determining shareholders entitled to notice of or to vote at a meeting of
shareholders, such books shall be closed for at least ten days immediately
preceding such meeting. In lieu of closing the stock transfer books, the Board
of Directors may fix in advance a date as the record date for any such
determination of shareholders, such date in any case to be not more than fifty
days and, in case of a meeting of shareholders, not less than ten days prior to
the date on which the particular action, requiring such determination of
shareholders, is to be taken. If the stock transfer books are not closed and no
record date is fixed for the determination of shareholders entitled to notice of
or to vote at a meeting of shareholders, or shareholders entitled to receive
payment of a dividend, the close of business on the date on which notice of the
meeting is mailed or on the date on which the resolution of the Board of
Directors


<PAGE>   4


declaring such dividend is adopted, as the case may be, shall be the record date
for such determination of shareholders. When a determination of shareholders
entitled to vote at any meeting of shareholders has been made as provided in
this section, such determination shall be applied to any adjournment thereof
except where the determination has been made through the closing of the stock
transfer books and the stated period of closing has expired.

     2.06. Voting Records. The officer or agent having charge of the stock
transfer books for shares of the corporation shall, before each meeting of
shareholders, make a complete record of the shareholders entitled to vote at
such meeting, or any adjournment thereof, with the address of and the number of
shares held by each. Such record shall be produced and kept open at the time and
place of the meeting and shall be subject to the inspection of any shareholder
during the whole time of the meeting for the purposes of the meeting. The
original stock transfer books shall be prima facie evidence as to who are the
shareholders entitled to examine such record or transfer books or to vote at any
meeting of shareholders. Failure to comply with the requirements of this section
shall not affect the validity of any action taken at such meeting.

     2.07. Quorum. Except as otherwise provided in the articles of
incorporation, a majority of the shares entitled to vote, represented in person
or by proxy, shall constitute a quorum at a meeting of shareholders. If a quorum
is present, the affirmative vote of the majority of the shares represented at
the meeting and entitled to vote on the subject matter shall be the act of the
shareholders unless the vote of a greater number or voting by classes is
required by law or the articles of incorporation. Though less than a quorum of
the outstanding shares are represented at a meeting, a majority of the shares so
represented may adjourn the meeting from time to time without further notice. At
such adjourned meeting at which a quorum shall be present or represented, any
business may be transacted which might have been transacted at the meeting as
originally notified.

     2.09. Proxies. At all meetings of shareholders, a shareholder entitled to
vote may vote in person or by proxy appointed in writing by the shareholder or
by his duly authorized attorney in fact. Such proxy shall be filed with the
Secretary of the corporation before or at the time of the meeting. Unless
otherwise provided in the proxy, a proxy may be revoked at any time before it is
voted, either by written notice filed with the Secretary or the acting secretary
of the meeting or by oral notice given by the shareholder to the presiding
officer during the meeting. The presence of a shareholder who has filed his
proxy shall not of itself constitute a revocation. No Proxy shall be valid after
eleven months from the date of its execution, unless otherwise provided in the
proxy. The Board of Directors shall have the power and authority to make rules
establishing presumptions as to the validity and sufficiency of proxies.

     2.10. Voting of Shares. Each outstanding share shall be entitled to one
vote upon each matter submitted to a vote at a meeting of shareholders, except

          (a) Other Corporations. Shares standing in the name of another
     corporation may be voted either in person or by proxy, by the president of
     such corporation or any other officer appointed by such president. A proxy
     executed by any principal officer of such other corporation or assistant
     thereto shall be conclusive evidence of the signer's authority to act, in
     the absence of express notice to this corporation, given in writing to the
     Secretary of this corporation, of the designation of some other person by
     the board of directors or the by-laws of such other corporation.

          (b) Legal Representatives and Fiduciaries. Shares held by an
     administrator, executor, guardian, conservator, trustee in bankruptcy,
     receiver, or assignee for creditors may be voted by him, either in person
     or by proxy, without a transfer of such shares into his name, provided that
     there is filed with the Secretary before or at the time of meeting proper
     evidence of his incumbency and the


<PAGE>   6


     number of shares held. Shares standing in the name of a fiduciary may be
     voted by him, either in person or by proxy. A proxy executed by a
     fiduciary, shall be conclusive evidence of the signer's authority to act,
     in the absence of express notice to this corporation, given in writing to
     the Secretary of this corporation, that such manner of voting is expressly
     prohibited or otherwise directed by the document creating the fiduciary
     relationship.

          (c) Pledgees. A shareholder whose shares are pledged shall be entitled
     to vote such shares until the shares have been transferred into the name of
     the pledgee, and thereafter the pledgee shall be entitled to vote the
     shares so transferred.

          (d) Treasury Stock and Subsidiaries. Neither treasury shares, nor
     shares held by another corporation if a majority of the shares entitled to
     vote for the election of directors of such other corporation is held by
     this corporation, shall be voted at any meeting or counted in determining
     the total number of outstanding shares entitled to vote, but shares of its
     own issue held by this corporation in a fiduciary capacity, or held by such
     other corporation in a fiduciary capacity, may be voted and shall be
     counted in determining the total number of outstanding shares entitled to
     vote.

          (e) Minors. Shares held by a minor may be voted by such minor in
     person or by proxy and no such vote shall be subject to disaffirmance or
     avoidance, unless prior to such vote the Secretary of the corporation has
     received written notice or has actual knowledge that such shareholder is a
     minor.

          (f) Incompetents and Spendthrifts. Shares held by an incompetent or
     spendthrift may be voted by such incompetent or spendthrift in person or by
     proxy and no such vote shall be subject to disaffirmance or avoidance,
     unless prior to such vote the Secretary of the corporation has actual
     knowledge that such shareholder has been adjudicated an incompetent or
     spendthrift or actual knowledge of filing of judicial proceedings for
     appointment of a guardian.


<PAGE>   7


          (g) Joint Tenants. Shares registered in the names of two or more
     individuals who are named in the registration as joint tenants may be voted
     in person or by proxy signed by any one or more of such individuals if
     either (i) no other such individual or his legal representative is present
     and claims the right to participate in the voting of such shares or prior
     to the vote files with the Secretary of the corporation a contrary written
     voting authorization or direction or written denial of authority of the
     individual present or signing the proxy proposed to be voted or (ii) all
     such other individuals are deceased and the Secretary of the corporation
     has no actual knowledge that the survivor has been adjudicated not to be
     the successor to the interests of those deceased.

     2.12. Waiver of Notice by Shareholders. Whenever any notice whatever is
required to be given to any shareholder of the corporation under the articles of
incorporation or by-laws or any provision of law, a waiver thereof in writing,
signed at any time, whether before or after the time of meeting, by the
shareholder entitled to such notice, shall be deemed equivalent to the giving of
such notice; provided that such waiver in respect to any matter of which notice
is required under any provision of the Kansas Business Corporation Law, shall
contain the same information as would have been required to be included in such
notice, except the time and place of meeting.

     2.13. Unanimous Consent without Meeting. Any action required or permitted
by the articles of incorporation or by-laws or any provision of law to be taken
at a meeting of the shareholders, may be taken without a meeting if a consent
in writing, setting forth the action so taken, shall be signed by all of the
shareholders entitled to vote with respect to the subject matter thereof.

director of the corporation under the articles of incorporation or by-laws or
any provision of law, a waiver thereof in writing, signed at any time, whether
before or after the time of meeting, by the director entitled to such notice,

<PAGE>   9


where a director attends a meeting and objects thereat to the transaction of any
business because the meeting is not lawfully called or convened. Neither the

director by vote of the shareholders, the shareholders shall have the right to
fill such vacancy at the same meeting or any adjournment thereof.

action with the person acting as the secretary of the meeting before the
adjournment thereof or shall forward such dissent by registered mail to the
Secretary of the corporation immediately after the adjournment of the meeting.
Such right to dissent shall not apply to a director who voted in favor of such
action.

affirmative vote of a majority of the number of directors as provided in Section
0.03 may designate one or more committees, each committee to consist of three or
more directors elected by the Board of Directors, which to the extent provided
in said resolution as initially adopted, and as thereafter supplemented or
amended by further resolution adopted by a like vote, shall have and may
exercise, when the Board of Directors is not in session, the powers of the Board
of Directors in the management of the business and affairs of the corporation,
except action in respect to dividends to shareholders, election of the principal
officers or the filling of vacancies in the Board of Directors or committees
created pursuant to this section. The Board of Directors may elect one or more
of its members as alternate members of any such committee who may take the place
of any absent member or members at any meeting of such committee, upon request
by the President or upon request by the chairman of such meeting. Each such
committee shall fix its own rules governing the conduct of its activities and

of Directors may request.

owner. Where a certificate for shares is presented to the corporation with a
request to register for transfer, the corporation shall not be liable to the
owner or any other person suffering loss as a result of such registration of
transfer if (a) there were on or with the certificate the necessary
endorsements, and (b) the corporation had no duty to inquire into adverse claims

less than the number of shares or the number of directors required to amend the
by-laws so that the by-laws would be consistent with such action, shall be given
the same effect as though the by-laws had been temporarily amended or suspended

and specified in the notice of such meeting.

are adopted by the Corporation, the annual meeting of the stockholders of the

holiday. The business to be transacted at such meeting shall be the election of
directors and such other business as shall be properly brought before the

designated for any annual meeting, or at any adjournment of such meeting, the
Board of Directors shall call a special meeting of the stockholders as soon as

meeting by attendance, either in person or by proxy, at the meeting, or by so

the stockholders.

stockholders shall consist of the holders of record of a majority of the shares
entitled to vote thereat, present in person or by proxy. If, however, such
majority shall not be present or represented at any such meeting, the
stockholders entitled to vote thereat, present, in person or by proxy, shall
have power to adjourn the meeting from time to time without notice other than an

     11.  (a) In order to determine the holders of record of the Corporation's
stock who are entitled to notice of meetings, to vote at a meeting or
adjournment thereof, and to receive payment of any dividend, or to make a
determination of the stockholders of record for any other proper purpose, the
Board of Directors of the Corporation may order that the Stock Transfer Books
be closed for a period not to exceed 60 days. If a purpose of such closing is
to determine who is entitled to notice of a meeting and to vote at such
meeting, the Stock Transfer Books shall be closed for at least 15 days
preceding such meeting.

          (b)  In lieu of closing the Stock Transfer Books, the Board of
Directors may fix a date as of the record date for such determination of
stockholders. Such date shall be no more than 60 days prior to the date of the
action which requires such determination, nor, in the case of a stockholders'
meeting, shall it be less than 15 days in advance of such meeting.

          (c)  If the Stock Transfer Books are not closed and no record is
fixed for such determination of the stockholders of record, the date of which
notice of the meeting is mailed, or on which the resolution of the Board of
Directors declaring a dividend is adopted, as the case may be, shall be the
record date for such determination of stockholders.

          (d)  When a determination of stockholders entitled to vote at any
meeting has been made as provided in this section, such determination shall
apply to any adjournment of such meeting, except when the determination has
been made by the closing of the Stock Transfer Books and the stated period of
closing has expired.

     12.  (a)  Meetings of the stockholders shall be presided over by the
President, or if he is not present, by a Vice-President, or if neither the
President nor a Vice-President is present, by a Chairman to be chosen by a
majority of the stockholders entitled to vote at the meeting who are present in
person or by proxy. The Secretary of the Corporation, or in the absence of the
Secretary, an Assistant Secretary, shall act as Secretary of every meeting, but
if neither the Secretary nor an Assistant Secretary is present, the presiding
officer of the meeting shall choose a person to act as Secretary of the meeting.

          (b)  The order of business shall be as follows:

                    1.   Call of meeting to order.
                    2.   Proof of notice of meeting.
                    3.   Reading of minutes of last previous
                         annual meeting.

                    5.   Reports of committees.

     13.  (a)  Except as otherwise provided in the Articles of Incorporation,
the Bylaws or the laws of the State of Florida, at every meeting of the
stockholders, each stockholder of the Corporation entitled to vote at such
meeting shall have, as to each matter submitted to a vote, one vote in person
or by proxy for each share of stock having voting rights registered in his name
on the books of the Corporation. A stockholder may vote his shares by a proxy
appointed by a written instrument signed by the stockholder or his duly
authorized attorney-in-fact and delivered to the Secretary of the meeting. No
proxy shall be valid after 11 months from the date of its execution.

          (b)  A majority of those shares entitled to vote and represented at
the meeting, a quorum being present, shall be the act of the meeting.

          (c)  At all elections of Directors, the voting shall be by written
ballot unless this requirement is unanimously waived by those shares entitled
to vote and represented at the meeting.

          (d)  Notwithstanding anything herein otherwise provided, when
stockholders who hold 80% of the stock having the right to vote at any meeting
shall be present at any meeting however called or notified and shall sign a
written consent thereto on the record of the meeting, the acts of such meeting
shall be as valid as if otherwise called and notified as hereinabove provided.

     14.  (a)  The Corporation shall keep the books and records and permit
inspection as provided in F.S.A. 608.39. A complete list of the stockholders of
the Corporation entitled to vote at the ensuing meeting, arranged in
alphabetical order, and showing the address of, and number of shares owned by
each stockholder, shall be prepared by the Secretary, or other officer of the
Corporation having charge of the Stock Transfer Books, which list shall be
produced at the meeting and shall be subject to inspection by any stockholder
at any time during the meeting.

          (b)  The original Stock Transfer Books shall be prima facie evidence
as to who are the stockholders entitled to examine such list or to vote at any
meeting of the stockholders.

          (c)  Failure to comply with the requirements of this section shall
not affect the validity of any action taken at such meeting of the stockholders.


                                   DIRECTORS

     15.  (a)  The property, affairs and business of the Corporation shall be
managed by a Board of Directors of [ILLEGIBLE] persons. Except as hereinafter
provided, directors shall be elected at the annual meeting of the stockholders
and each director shall serve for one year and until his successor shall be
elected and qualified.
<PAGE>   5
         (b) The number of directors may be increased or decreased from time to
time by an amendment to these Bylaws. Any increased number of directors shall be
elected by the stockholders at the next regular annual meeting or at a special
meeting called for that purpose. The number of directors shall never be less
than the minimum nor more than the maximum number of directors as provided in
the Articles of Incorporation.

         (c) Directors need not be stockholder of the Corporation.

         (d) A majority of the directors in office shall be necessary to
constitute a quorum for the transaction of business. Members of the Board of
Directors shall be deemed present at a meeting of such Board of Directors if a
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other is used. If, at any
meeting of the Board of Directors, there shall be less than a quorum present, a
majority of those present may adjourn the meeting, without further notice, from
time to time until a quorum shall have been obtained. In case there are
vacancies on the Board of Directors, other than vacancies created by the
removal of a director or directors by the stockholder or by an increase in the
number of directors, the remaining directors, although less than a quorum, may
by a majority vote, elect a successor or successors for the unexpired term or
terms.

         16. Meetings of the Board of Directors may be held either within or
without the State of Florida. Regular meetings of the Board of Directors shall
be held at such times as are fixed from time to time by resolution of the
Board. Special meetings may be held at any time upon call of the President,
Vice-President or 50% or more of the directors, upon written or telegraphic
notice deposited in the U.S. mail or delivered to the telegraph company at
least 5 days prior to the day of the meeting. A meeting of the Board of
Directors may be held without notice immediately following the annual meeting
of the stockholders. Notice need not be given of regular meetings of the Board
of Directors held at the time fixed by resolution of the Board of Directors nor
need notice be given of adjourned meetings. Meetings may be held at any time
without notice if all the directors are present or if, before the meeting,
those not present waive such notice in writing. Notice of a meeting of the
Board of Directors need not state the purpose of, nor the business to be
transacted at such meeting.

         17. At any meeting of the stockholder, any director or directors may be
removed from office, without assignment of any reason therefor, by a majority
vote of those shares entitled to vote and represented at the meeting. When any
director or directors are removed, new directors may be elected at the same
meeting of the stockholders for the unexpired term of the director or directors
removed. If the stockholders fail to elect persons to fill the unexpired term or
terms of the director or directors removed, such unexpired term or terms shall
be considered vacancies on the Board to be filled by the remaining directors.
<PAGE>   6
         18. (a) The Corporation shall indemnify each of its directors and
officers, whether or not then in office (and his executor, administrator and
heirs), against all reasonable expenses actually and necessarily incurred by him
in connection with the defense of any litigation to which he may have been made
a party because he is or was a director or officer of the Corporation.  He shall
have no right to reimbursement, however, in relation to matters as to which he
has been adjudged liable to the Corporation for negligence or misconduct in the
performance of his duties.  The right to indemnity for expenses will also apply
to the expenses of suits which are compromised or settled if the court having
jurisdiction of the matter shall approve such settlement.

         (b) The foregoing right of indemnification shall be in addition to and
not exclusive of, all other rights to which such director or office may be
entitled including, without limiting the generality of the foregoing, all rights
of indemnification and rights to payment of expenses as provided in F.S.A.
Section 608.13 (14) (15) and (16) and the Board of Directors may authorize the
purchase and maintenance of insurance to the extent as provided in F.S.A.
Section 608.13(17).

         19. Compensation and reimbursement for reasonable expenses of Directors
may be paid if authorized by resolution of the Board of Directors.  Any Director
receiving compensation under this provision shall not be barred from serving the
Corporation in any other capacity and receiving reasonable compensation for such
other services.

         20. (a) The Board of Directors by a  resolution or resolutions adopted
by a majority of the members of the whole Board, may appoint an Executive
Committee and such other committees as it may deem appropriate.  Each such
committee shall consist of members of the Board of Directors or officers of the
Corporation provided that the Executive Committee shall be at least two in
number and all of the members of such Committee shall be members of the Board of
Directors.  The Executive Committee shall have and may exercise any and all
powers of the Board of Directors in the management of the business and affairs
of this Corporation and each other committee shall have and exercise such powers
as shall be conferred and/or authorized by the resolution constituting it.  A
majority of any such committee may determine its action and may fix the time and
place of its meetings, unless provided otherwise by the Board of Directors.  The
Board of Directors shall have the power at any time, to fill vacancies in, to
change the size of membership of, and to discharge any such committee.

         (b) Each such committee shall keep a written record of its acts and
proceedings and shall submit such record to the Board of Directors at each
regular meeting thereof and at such other times as requested by the Board of
Directors.  Failure to submit such record, or failure of the Board to approve
any action indicated therein will not, however, invalidate such action to the
extent it has been carried out by the Corporation prior to the time the record
of such action was, or should have been submitted to the Board of Directors as
herein provided.

<PAGE>   7
         (b) The Vice-Presidents, in the order designated by the Board of
Directors, shall exercise the functions of the President during the absence or
disability of the President.  Each Vice-President shall have such other duties
as are assigned to him from time to time by the Board of Directors.

         (c) The Secretary, and the Treasurer shall perform such duties as are
incident to their offices, or are properly required of them by the Board of
Directors, or are assigned to them by the Articles of Incorporation or these
Bylaws.  The Assistant Secretaries, in the order of their seniority, shall, in
the absence of the Secretary, perform the duties and exercise the powers of the
Secretary, and shall perform such other duties as may be assigned by the Board
of Directors.

         (d) Other subordinate officers appointed by the Board of Directors
shall exercise such powers and perform such duties as may be delegated to them
by the resolutions appointing them, or by subsequent resolutions adopted from
time to time.

         (e) In case of the absence or disability of any officer of the
Corporation and of any person hereby authorized to act in his place during such
period of absence or disability, the Board of Directors may from time to time
delegate the powers and duties of such officer to any other officer, or any
director, or any other person whom it may select.

         (f) The Board of Directors, by resolution, may require any or all of
the officers of the Corporation to give bonds in favor of the Corporation, with
sufficient surety or sureties, and in such amounts as the Board of Directors may
fix, conditioned for the faithful performance of the duties of their respective
offices.

         27. The salaries of all officers of the Corporation shall be fixed by
the Board of Directors. No officer shall be ineligible to receive such salary by
reason of the fact that he is also a Director of the Corporation and receiving
compensation therefor.

         28. (a) The interest of each stockholder of the Corporation shall be
evidenced by certificates for shares of stock, certifying the number of shares
represented thereby and in such form not inconsistent with the Articles of
Incorporation as the Board of Directors may from time to time prescribe.

         (b) The certificate of stock shall be signed by the President or a
Vice-President and by the Secretary or an Assistant Secretary or the Treasurer,
and sealed with the seal of the Corporation. Such seal may be a facsimile,
engraved or printed.  Where any certificate is manually signed by a transfer
agent or a transfer clerk or by a registrar the signatures of the President,
Vice-President, Secretary, Assistant Secretary, or Treasurer upon such
certificate may be facsimiles, engraved or printed.  In case any officer who has
signed or whose facsimile signature has been placed upon any certificate shall
have ceased to be such before the certificate is issued, it may be issued by the
Corporation with the same effect as if such officer had not ceased to be such at
the time of its issue.

<PAGE>   8
             (c) During the intervals between meetings of the Board of
Directors, the Executive Committee, if appointed hereunder, may have and shall
exercise all the powers of the Board of Directors in the management of the
affairs, business and property of the Corporation, in such manner as the
Executive Committee shall deem for the best interests of the Corporation in all
cases in which specific directions shall not have been given by the Board of
Directors. The Executive Committee shall not have power to fill vacancies in
said Committee or in the Board of Directors or to make or amend the Bylaws of
the Corporation.

         21. Subject always to the provisions of law and the Articles of
Incorporation, the Board of Directors shall have full power to determine whether
any, and if so, what part, of the funds legally available for the payment of
dividends shall be declared in dividends and paid to the stockholders of the
Corporation. The Board of Directors may fix a sum which may be set aside or
reserved over and above the paid-in capital of the Corporation for working
capital or as a reserve for any proper purpose, and from time to time may
increase, diminish and vary such fund in the Board's absolute judgment and
discretion.

                                    OFFICERS

         22. The officers of the Corporation shall be a President, one or more

Directors at the first meeting of the Board following the stockholders' annual
meeting, or as soon thereafter as is conveniently possible.  Subordinate
officers may be elected from time to time.  Each officer shall serve until his
successor shall have been chosen and qualified, or until his death, resignation
or removal.

         24. Any officer may be removed from office, with or without cause, at
any time by the affirmative vote of a majority of the Board of Directors then in
office.  Such removal shall not prejudice the contract rights, if any, of the
person so removed.

         25. Any vacancy in an office from any cause may be filled for the
unexpired portion of the term by the Board of Directors.

         26. (a) The President shall preside at all meetings of the stockholders
and the Board of Directors.  He shall have general supervision of the affairs of
the Corporation, shall sign or countersign all certificates, contracts or other
instruments of the Corporation as authorized by the Board of Directors, shall

the books of the Corporation by the holder thereof in person or by his
attorney, upon surrender for cancellation of the certificate or certificates,
with an assignment and power of transfer endorsed thereon or attached thereto
duly executed, and with such proof of authenticity of the signature as the
Corporation or its agent may reasonably require.

     30.  No certificate for shares of stock in the Corporation shall be issued
in place of any certificate alleged to have been lost, stolen or destroyed,

secured by such security as the Board of Directors in its discretion may
require.

     31.  The Board of Directors may appoint one or more transfer agents or
transfer clerks and one or more registrars, and may require all certificates

to act and to vote at any meeting of security holders of other corporations in
which Corporation may hold securities. At such meeting, the President shall

corporation has been recovered.

1.5               Adjournments. Any meeting of shareholders, annual or special,
                  may adjourn from time to time to reconvene at the same or some
                  other place, and notice need not be given of any such
                  adjourned meeting if the time and place thereof are announced

                  which might have been transacted at the original meeting. If
                  after the adjournment of a new record date is fixed for the
                  adjourned meeting, a notice of the adjourned meeting shall be
                  given to each shareholder of record entitled to vote at the
                  meeting.

1.7               Attendance at Meeting. A shareholder's attendance at a
                  meeting constitutes a waiver of objection to:

                  (A)   lack of notice or defective notice of the meeting,
                        unless the shareholder at the beginning of the meeting
                        objects to the holding of the meeting or transacting
                        business at the meeting; and

                  (B)   consideration of a particular matter at the meeting that
                        is not within the purposes described in the meeting
                        notice, unless the shareholder objects to considering
                        the matter when it is presented.

1.8               Electronic Participation. A shareholder shall be deemed to be

                  conference telephone or by other

                  equipment and the names of the participants in the conference
                  are divulged to all participants.

1.9               Quorum. At every meeting of the shareholders, the holders of
                  record of a majority of the outstanding shares of stock of the
                  Corporation entitled to vote at such meeting, whether present
                  in person or represented by proxy, shall constitute a quorum.

                        action.

                  Nothing in this Paragraph shall affect the rights of a
                  shareholder and his transferee or transferor as between
                  themselves.

1.11              Inspection of List of Shareholders. The officer or agent
                  having charge of the stock transfer books for shares of the
                  Corporation shall make and certify a complete list of the
                  shareholders entitled to vote at a shareholders meeting or
                  any adjournment thereof. The list shall:

                  (A)   Be arranged alphabetically within each class and series,
                        with the address of and the number of shares held by
                        each shareholder.

                  (B)   Be produced at the time and place of the meeting.

                        entitled to examine the list or to vote at the meeting.

                  shareholders meeting, may appoint one or more inspectors to
                  act at the meeting or any adjournment thereof. If inspectors
                  are not so appointed, the person presiding at a shareholders
                  meeting may, and on request of a shareholder entitled to vote
                  thereat shall, appoint one (1) or more inspectors. In case a
                  person appointed fails to appear or act, the vacancy may be
                  filled by appointment made by the Board in advance of the
                  meeting or at the meeting by the person presiding thereat.


                  The inspectors shall determine the number of shares
                  outstanding and the voting power of each, the shares
                  represented at the meeting, the existence of a quorum, the
                  validity and effect of proxies, and shall receive votes,
                  ballots or consents, hear and determine challenges and
                  questions arising in connection with the right to vote, count
                  and tabulate votes, ballots or consents, determine the result,
                  and do such acts as are proper to conduct the election or vote
                  with fairness to all shareholders. On request of the person
                  presiding at the meeting or a shareholder entitled to vote
                  thereat, the inspectors shall make and execute a written
                  report to the person presiding at the meeting of any of the
                  facts found by them and matters determined by them.

                  determined by the Chairman of the meeting.

                  Except as otherwise required by the Articles of Incorporation,
                  these Bylaws, or the laws of the State of Michigan, if an
                  action other than the election of Directors is to be taken by
                  vote of the shareholders, it shall be authorized by a majority
                  of the votes cast by the holders of shares entitled to vote on
                  the action. Directors shall be elected by a plurality of the
                  votes cast at an election.

1.14.             Vote by Shareholder Corporation. Shares standing in the name
                  of another domestic or foreign corporation may be voted by an
                  officer or agent, or by proxy appointed by an officer or agent
                  or by some other person, who by action of its board or
                  pursuant to its bylaws shall be appointed to vote the shares.

1.15.             Voting of Securities Owned by the Corporation. Subject always
                  to the specific directions of the Board of Directors, any
                  shares or other securities issued by any other company and
                  owned or controlled by the Corporation may be voted at any
                  meeting of security holders of such other company by the
                  President of the Corporation or by proxy appointed by him, or
                  in the absence of the President and his proxy by the Treasurer
                  of the Corporation, or by proxy appointed by him, or in the
                  absence of the President and Treasurer, by the Secretary of
                  the Corporation, or by proxy appointed by him. Such proxy or
                  consent in respect to any shares or other securities issued by
                  any other company and owned by the Corporation, shall be
                  executed in the name of the Corporation by the President, the
                  Treasurer or the Secretary of the Corporation without
                  necessity of any authorization by the Board of Directors,
                  affixation or corporate seal or countersignature or
                  attestation by another officer. Any person or persons
                  designated in the manner above stated as the proxy or proxies
                  of the Corporation shall have the full right, power and
                  authority to vote the shares or other securities issued by
                  such other company and owned by the Corporation the same as
                  such shares or other securities might be voted by the
                  Corporation.

1.16              Pledged Shares. A shareholder whose shares are pledged is
                  entitled to vote the shares until they have been transferred
                  into the name of the pledgee, or a nominee of the pledgee.

                  permitted to be taken at an Annual or Special Meeting of
                  shareholders may be taken without a meeting, without prior
                  notice and without a vote, if before or after the action, all

                  or Special Meeting of shareholders may be taken without a
                  meeting, without prior notice and without a vote, if consents
                  in writing, setting forth the action so taken, are signed by
                  the holders of outstanding shares having not less than the

                  to the Corporation's registered office shall be by hand or by
                  certified or registered mail, return receipt requested. Prompt
                  notice of the taking of the corporate action without a meeting
                  by less than unanimous written consent shall be given to
                  shareholders who have not consented in writing.

                STOCK BOOKS AND RECORDS; REPORTS TO SHAREHOLDERS

2.1               Books of Account and Stock Books. The Corporation shall keep
                  books and records of account and minutes of the proceedings of
                  the shareholders, board and executive committee, if any. The
                  Corporation shall keep at its registered office, or at the
                  office of its transfer agent in or outside this state, records
                  containing the names and addresses of all shareholders, the
                  number, class and series of shares held by each and the dates
                  when they respectively became holders of record. Any of the

                  other form capable of being converted into written form within

                  a reasonable time. The Corporation shall convert into written
                  form without charge any record not in written form unless
                  requested otherwise by a person entitled to inspect the
                  record.

2.2               Financial Statements. Within four months of the end of its
                  fiscal year, the Corporation shall mail to each shareholder
                  its balance sheet as of the end of the preceding fiscal year;
                  its statement of income for the fiscal year; and, if prepared
                  by the Corporation, its statement of source and application of
                  funds for the fiscal year. The same shall be furnished to any
                  shareholder at any time upon written request from such
                  shareholder.

2.3               Examination of Stock Books and Records. Any shareholder of
                  record, in person or by attorney or other agent, shall have
                  the right during the usual hours of business to inspect for
                  any proper purpose the Corporation's stock ledger, a list of
                  its shareholders, and its other books and records, if the
                  shareholder gives the Corporation written demand describing
                  with reasonable particularity his or her purpose and the
                  records he or she desires to inspect, and the records sought
                  are directly connected with the purpose. A proper purpose
                  shall mean a purpose reasonably related to such person's
                  interest as a shareholder. The demand shall be delivered to
                  the Corporation at its registered office in Michigan or at its
                  principal place of business. In every instance where an
                  attorney or other agent shall be the person who seeks to
                  inspect, the demand shall be accompanied by a power of
                  attorney or other writing which authorizes the attorney or
                  other agent to act on behalf of the Shareholder. A holder of a
                  voting trust certificate representing shares of the
                  Corporation is deemed a shareholder for the purpose of this
                  Paragraph.


                                   ARTICLE 3

                                 CAPITAL STOCK

3.1               Certificates. Every shareholder of this Corporation shall be
                  entitled to a certificate of his shares signed by the Chairman
                  of the Board, Vice-Chairman of the Board, President or Vice
                  President certifying the number and class of shares, and
                  designation of the series, if any, represented by such
                  certificate; provided that where such certificate is signed by
                  a transfer agent acting on behalf of the Corporation, and by a
                  registrar, the signature of any such officer may be facsimile.

3.2               Transfer. Except as otherwise provided by a written agreement
                  between the Corporation and a shareholder,

                  shares shall be transferable only on the books of the
                  Corporation by the person named in the certificate, or by
                  attorney lawfully constituted in writing, and upon surrender
                  of the certificates therefor. A record shall be made of every
                  such transfer and issue. Whenever any transfer is made for
                  collateral security and not absolutely, the fact shall be so
                  expressed in the entry of such transfer.

3.3               Lost, Destroyed, or Stolen Certificates. Where the owner
                  claims that his certificate for shares has been lost,
                  destroyed, or wrongfully taken, a new certificate shall be
                  issued in place thereof if the owner (a) so requests before
                  the Corporation has notice that such shares have been acquired
                  by a bona fide purchaser, and (b) files with the Corporation a
                  sufficient indemnity bond, and (c) satisfies such other
                  reasonable requirements as the Board of Directors may
                  prescribe.

3.4               Registered Shareholder. The Corporation shall be entitled to
                  treat the person in whose name any share of stock is
                  registered as the owner of it for purposes of dividends and
                  other distributions or for any recapitalization, merger,
                  reorganization, sale of assets, or liquidation and for the
                  purpose of votes, approvals, and consents by shareholders, and
                  for the purpose of notices to shareholders and for all other
                  purposes whatever, and shall not be bound to recognize any
                  equitable or other claim to or interest in the shares by any
                  other person, whether or not the Corporation shall have notice
                  of it, except as expressly required by the laws of the State
                  of Michigan or Paragraph 3.8.

3.5               Lien for Shareholder Indebtedness. The Corporation shall have
                  a lien upon the capital stock of any holder thereof who is
                  indebted to the Corporation in any way and shall have the
                  right to cancel the holder's right in such amount of the
                  capital stock as is equivalent to such indebtedness in payment
                  and satisfaction thereof and the discharge of such lien.
                  Further, the Corporation shall have the right to not accept
                  any transfer of capital stock by the holder thereof which will
                  impair the security of its lien for the balance of the
                  indebtedness then owing by such holder to the Corporation.

3.6               Consideration for Shares. Shares of stock may be issued for
                  consideration consisting of any tangible or intangible
                  property or benefit to the Corporation, including but not
                  limited to cash, promissory notes, services performed, or
                  contracts for services to be performed.

3.7               Transfer Agent and Registrar. The Board of Directors may
                  appoint a transfer agent and a registrar of transfer, and may
                  require all certificates of shares to bear the signature of
                  such transfer agent and of such registrar of transfers.

3.8               Nominees. The Board of Directors may establish a procedure
                  by which the beneficial owner of shares that are registered in
                  the name of a nominee is recognized by the Corporation as the
                  shareholder. The procedure established may determine the
                  extent of this recognition. The procedure may set forth any of
                  the following:

                  (A)   The types of nominees to which it applies.

                  (B)   The rights or privileges that the Corporation recognizes
                        in a beneficial owner.

                        nominee.

                  (D)   The information that must be provided when the procedure
                        is selected.

                  (E)   The period for which selection of the procedure is
                        effective.

                  (F)   Other aspects of the rights and duties created.

3.9               Regulations. The Board of Directors shall have power and
                  authority to make such rules and regulations as the Board
                  shall deem expedient regulating the issue, transfer and
                  registration of certificates for share of the Corporation.

                                    ARTICLE 4

                               BOARD OF DIRECTORS

4.1               Number and Term of Office. The business, property and
                  affairs of the Corporation shall be managed by or under the
                  direction of the Board of Directors. The Board of Directors
                  shall consist of one (1) or more members, the number thereof
                  to be determined initially by the Incorporator(s), and
                  thereafter from time to time by a resolution adopted by a
                  majority of the shareholders. Directors need not be
                  shareholders. The first Board of Directors shall hold office
                  until the first Annual Meeting of shareholders. At each
                  Annual Meeting of shareholders, the shareholders shall elect
                  directors to hold office until the succeeding Annual Meeting.
                  The shareholders or Board of Directors may designate one or
                  more directors as an "independent director". A director

                                        9

<PAGE>   12


                  shall hold office for the term for which he is elected and
                  until his successor is elected and qualified, or until his
                  resignation or removal.

4.2               Removal or Resignation. Except as otherwise provided in the
                  Articles of Incorporation, any director of the entire Board of
                  Directors may be removed, with or without cause, by the
                  holders of a majority of the shares then entitled to vote at
                  an election of directors. Any director may resign at any time
                  by giving written notice to the Board of Directors, the
                  Chairman of the Board, if any, or the President or Secretary
                  of the Corporation. Unless a later date is specified in such
                  written notice, a resignation shall take effect upon delivery
                  thereof to the Board of Directors or the designated officer.
                  It shall not be necessary for a resignation to be accepted
                  before it becomes effective.

4.3               Vacancies. Except otherwise provided in the Articles of
                  Incorporation, a vacancy occurring in the Board (including a
                  vacancy resulting from an increase in the number of directors)
                  may be filled by the shareholders or by the affirmative vote
                  of a majority of the remaining directors though less than a
                  quorum of the Board. Except as otherwise provided in the
                  Articles of Incorporation if the holders of any class or
                  classes of stock or series are entitled to elect one (1) or
                  more directors to the exclusion of other shareholders,
                  vacancies of that class or classes or series may be filled by
                  the holders of shares of that class or classes of shares, or
                  series. A vacancy that will occur at a specific date, by
                  reason of a resignation effective at a later date, may be
                  filled before the vacancy occurs but the newly elected or
                  appointed director may not take office until the vacancy
                  occurs.

4.4               Organizational Meeting. At the place of holding the Annual
                  Meeting of shareholders and immediately following the same,
                  the Board of Directors as constituted upon final adjournment
                  of such Annual Meeting shall convene without notice for the
                  purpose of electing officers and transacting any other
                  business properly brought before it; provided, that the
                  organizational meeting in any year may be held at a different
                  time and place than that herein provided by consent of a
                  majority of the Directors of such new Board.

4.5               Regular Meetings. Regular Meetings of the Board of Directors
                  shall be held at such time and place as the Board of Directors
                  shall from time to time determine by resolution of the Board
                  of Directors or by Waiver of Notice and Consent. No notice of
                  Regular Meetings of the

                                       10


<PAGE>   13

                  Board shall be required:

4.6               Special Meetings. Special Meetings of the Board of Directors
                  may be called by the Chairman of the Board, or if that
                  position is not filled, by the President, or a majority of the
                  Directors in office at that time of the call, whenever in his
                  or their judgment it may be necessary, by giving reasonable
                  notice, either personally or by mail, telegram, or telecopier,
                  of the time and place of such meeting. A notice that is mailed
                  shall be deemed to be given when deposited in the United
                  States mail with postage fully prepaid, addressed to such
                  director as his address appears on the records of the
                  Corporation. Any action taken at any such meeting shall not be
                  invalidated for want of notice if such notice shall be waived
                  as herein provided. A telecopied notice shall be deemed to be
                  given when it is transmitted by telecopier to the director's
                  home or place of business.

4.7               Waiver of Notice. Notice of the time and place of any meeting
                  of the Board of Directors may be waived in writing or by
                  telegram, radiogram, cablegram, or telecopier, either before
                  or after such meeting has been held.

                  A director's attendance at or participation in a Board
                  meeting constitutes a waiver of notice of the meeting,
                  unless at the beginning of the meeting (or upon the
                  director's arrival) the director objects to the meeting or
                  transacting of business at the meeting and does not
                  thereafter vote for or assent to any action taken at the
                  meeting.

4.8               Purpose. Neither the business to be transacted nor the purpose
                  of a Regular or Special Meeting need be specified in the
                  notice or waiver of notice of the meeting.

4.9               Electronic Participation. A member of the Board of a committee
                  designated by the Board may participate in a meeting by means
                  of a conference telephone or similar communications equipment
                  through which all persons participating in the meeting can
                  communicate with each other. Participation in a meeting
                  pursuant to this Paragraph constitutes presence in person at
                  the meeting.

4.10              Quorum. A majority of the directors in office or of the
                  members of a committee of the Board shall constitute a quorum
                  for the transaction of business, unless the Board resolution
                  establishing the committee provides for a larger or smaller
                  number. If there shall be less than a quorum present at any
                  meeting of the Board of Directors, a majority of the directors
                  present may adjourn the

                                       11


<PAGE>   14


                  meeting from time to time without notice other than
                  announcement at the meeting until a quorum shall be present,
                  at which time any business may be transacted which might have
                  been transacted at the meeting as first convened had there
                  been a quorum present. The acts or a majority of the directors
                  of committee members present at any meeting at which a quorum
                  is present shall be the acts of the Board or of the committee,
                  unless the vote of a larger number is required by the Board
                  resolution establishing the committee.

4.11              Appointment of Committees. The Board may designate one
                  (1) or more committees, each committee to consist of one (1)
                  or more of the directors of the Corporation. The Board may
                  designate one (1) or more directors as alternate members of a
                  committee, who may replace an absent or disqualified member at
                  a meeting of the committee. In the absence or disqualification
                  of a member of a committee, the members thereof present at a
                  meeting and not disqualified from voting, whether or not they
                  constitute a quorum, may unanimously appoint another member of
                  the Board to act at the meeting in place of such an absent or
                  disqualified member. A committee, and each member thereof,
                  shall serve at the pleasure of the Board.

4.12              Powers of Committees. A committee to the extent provided in
                  the resolution of the Board, may exercise all powers and
                  authority of the Board in management of the business and
                  affairs of the Corporation. However, such a committee does not
                  have power or authority to do any of the following:

                  (A)   Amend the Articles of Incorporation.

                  (B)   Adopt an agreement of merger or consolidation.

                  (C)   Recommend to shareholders the sale, lease or exchange of
                        all or substantially all of the Corporation's property
                        and assets.

                  (D)   Recommend to shareholders a dissolution of the
                        Corporation or a revocation of a dissolution.

                  (E)   Amend the Bylaws of the Corporation.

                  (F)   Fill vacancies in the Board of Directors.

4.13              Action by Unanimous Written Consent. Action required or
                  permitted to be taken under authorization voted at a meeting
                  of the Board or a committee of the Board, may be taken without
                  a meeting if, before or after the action,

                                       12


<PAGE>   15

                  of law;


                  (C)   For a violation of Section 551 (1) of the Michigan
                        Business Corporation Act;

                  (D)   For any transaction from which the director derived an
                        improper personal benefit; and

                  (E)   For any acts or omissions occurring before the date this
                        Article is filed by the Michigan Department of Commerce.

                  If the Michigan Business Corporation Act is hereafter amended
                  to further eliminate or limit the liability of a director,
                  then a director of the Corporation (in addition to the
                  circumstances in which a director is not personally liable as
                  set forth in the preceding paragraph) shall not be liable to
                  the Corporation or its shareholders to the fullest extent
                  permitted by the Michigan Business Corporation Act, as so
                  amended. Any repeal or modification of this Article by the
                  shareholders of the Corporation shall not adversely affect any
                  right or protection of a director of the Corporation existing
                  at the time of such repeal or modification.

                                    ARTICLE 5

                           DIVIDENDS AND DISTRIBUTIONS

5.1               Dividends. The Board of Directors may authorize and the
                  Corporation may pay dividends or make other distributions,
                  except when the distribution would be contrary to the laws of
                  the State of Michigan or any restriction contained in the
                  Articles of Incorporation.


                                    ARTICLE 6

                       TRANSACTIONS WITH THE CORPORATION;
                    LOANS TO DIRECTORS, OFFICERS OR EMPLOYEES

6.1               Interested Transactions. A transaction in which a director or
                  officer is determined to have an interest shall not, because
                  of the interest, be enjoined, set aside, or give rise to an
                  award of damages or other sanctions, in a proceeding by a
                  shareholder or by or in the right of the Corporation, if the
                  person interested in the transaction establishes any of the
                  following:

                  (A)   The transaction was fair to the Corporation at the time
                        entered into.

                  (B)   The material facts of the transaction and the

                                       14

<PAGE>   16


                  all members of the Board then in office or of the committee
                  consent to the action in writing. The written consents shall
                  be filed with the minutes of the proceedings of the Board or
                  the committee. The consent has the same effect as a vote of
                  the Board or committee for all purposes.

4.14              Election of Officers. The Board of Directors shall select a
                  President, a Secretary and a Treasurer and may elect a
                  Chairman and Vice Chairman of the Board. None of said
                  officers, except the Chairman and Vice Chairman of the Board,
                  need be a director. The Board of Directors shall have the
                  power to appoint such other officers and agents as the Board
                  may deem necessary for the transaction of the business of the
                  Corporation, including the power to appoint one or more Vice
                  Presidents and one or more attorneys-in-fact to convey or deal
                  with corporate real estate.

4.15              Compensation. Reasonable compensation of directors and
                  officers may be fixed by the Board.

4.16              Payments to be Reimbursed. Any payment made to an officer or
                  employee or any expense reimbursed on his behalf, which shall
                  be disallowed in whole or in part as a deductible expense by
                  the Internal Revenue Service, shall be reimbursed by such
                  officer or employee to the Corporation to the full extent of
                  such disallowance. The Board of Directors shall enforce

                        member if the director or officer reasonably believes
                        the committee merits confidence.

                  A director or officer is not entitled to rely on the
                  information set forth above if he or she has knowledge
                  concerning the matter in question that makes reliance

                                CORPORATE OFFICE

The office and principal place of business of the corporation shall be located
at 1947 S. Carolina Avenue, NE, St. Petersburg, FL 33702.

                                   ARTICLE II

                                  SHAREHOLDERS

Section One. Annual Meeting.

(a) An annual meeting of shareholders shall be held in each year on the third
Friday in December at 9:00 a.m., unless such day should fall on a legal holiday,
in which event the meeting shall be held at the same hour on the next succeeding
business day that is not a legal holiday. Annual meetings shall be held at the
principal office of the corporation or at such other place within the State of
Florida as may be determined by the board of directors and designated in the
notice of such meeting.

(b) If, in any year, the election of directors is not held at the annual meeting
of shareholders or at any adjournment of such meeting, the board of directors
shall call a special meeting of shareholders as soon afterwards as reasonably
possible for the purpose of holding such election and transacting such other
business as may properly be brought before the meeting. In the event the board
of directors fails to call a special meeting within two months after the date
prescribed for the annual meeting, any shareholder may call a meeting, and at
the meeting the shareholders may elect directors and transact all other business
properly brought before the meeting.

(c)  No change in the time or place of a meeting for the election of directors
may be made within 10 days of the date for which such meeting is scheduled, and
written notice of any change in the date of such a meeting must be given to each
shareholder of record at least 10 days prior to the date for which any such
meeting is rescheduled.

(d) Any shareholders' meeting, annual or special, may be adjourned from time to
time by the affirmative vote of a majority of the shares represented at such
meeting either in person or by proxy. An adjournment may be voted regardless of
whether a quorum is present. When a shareholders' meeting is adjourned for 10
days or more, notice of the adjourned meeting must be given as in the case of an
original meeting. When a meeting is adjourned for less than 10 days, no notice
of the time and place of the adjourned meeting need be given other than by
announcement at the meeting at which the adjournment is voted.

Section Two. Special Meetings. Special meetings of shareholders may be called
for any purpose. Such meetings may be called at any time

by the president, the board of directors, or by the holders of not less than ten
percent of all the outstanding shares of the corporation. On the written request
of any person or persons entitled to call a special meeting, the secretary shall
inform the board of directors as to such call, and the board shall fix a time
and place for the meeting. If the board fails to fix such a time and place, the
meeting shall be held at the principal office of the corporation at a time fixed
by the secretary.

Section Three. Action by Shareholders by Written Consent.

(a) Any action required or permitted by law to be taken at a meeting of
shareholders, may be taken without a meeting, without prior notice and without a
vote, if a consent in writing, setting forth the action so taken, is dated and
signed by the approving shareholders having the requisite number of votes of
each voting group entitled to vote having not less than the minimum number of
votes with respect to each voting group that would be necessary to authorize or
take such action at a meeting at which all voting groups and shares entitled to
vote were present and voted.

(b) Within ten days after obtaining such authorization by written consent,
notice shall be given to those shareholders who have not consented in writing or
who are not entitled to vote on the action. Such notice shall fairly summarize
the material features of the action so authorized and, if the action is a
merger, consolidation, or sale or exchange of assets, for which dissenters'
rights are provided by law, shall contain a clear statement of the right of
dissenting shareholders to be paid the fair value of their shares on compliance
with the applicable statutory provisions.

Section Four. Notice of Meetings. Written or printed notice stating the place,
day, and hour of the meeting, and, in the case of a special meeting, the purpose
or purposes for which the meeting is called, shall be delivered not less than 10
nor more than 60 days before the date of the meeting, either personally or by
first-class mail, by or at the direction of the president, secretary, or the
officer or persons calling the meeting, to each shareholder of record entitled
to vote at the meeting. If the notice is mailed at least 30 days before the date
of the meeting, it may be done by a class of United States mail other than first
class. If mailed, such notice shall be deemed to have been delivered when
deposited in the United States mail, postage prepaid, addressed to the
shareholder to receive it at his or her address as it then appears on the
records of the corporation.

Section Five. Waiver of Notice. A shareholder may waive notice of any annual or
special meeting by signing a written notice of waiver either before or after the
date of such meeting.

Section Six. Record Date.

(a) For the purpose of determining shareholders entitled to notice of or to vote
at any meeting of shareholders, or demand a special

meeting, or in order to make a determination of shareholders for any other
proper purpose, the board of directors may fix the record date which may not
precede the date on which the resolution fixing the record date is adopted nor
may it be more than 70 days before the meeting or action requiring a
determination of shareholders.

(b) If not otherwise provided and no prior action is required by the board of
directors, the record date for determining shareholders entitled to demand a
special meeting is the date the first shareholder delivers his or her demand to
the corporation. If prior action is required by the board of directors, the
record date for determining shareholders entitled to take action without a
meeting is at the close of business on the day on which the board of directors
adopts the resolution taking such prior action.

(c) If not otherwise provided, the record date for determining shareholders
entitled to notice of and to vote at annual or special shareholders' meeting is
the close of business on the day before the first notice is delivered to
shareholders.

(d) A determination of shareholders entitled to notice of or to vote at any
meeting of shareholders is effective for any adjournment of the meeting unless
the board of directors fixes a new record date.

Section Seven. Quorum. The presence, at any shareholders' meeting, in person or
by proxy, of persons entitled to vote a majority of the shares of the
corporation then outstanding shall constitute a quorum for the transaction of
business. In determining whether quorum requirements for a meeting have been
met, any share that has been enjoined from voting or that for any reason cannot
be lawfully voted shall not be counted.

Section Eight. Proxies. Every person entitled to vote at a shareholders' meeting
of the corporation, or entitled to execute written consent authorizing action in
lieu of a meeting, may do so either in person or by proxy executed in writing by
the shareholder or by his or her duly authorized attorney-in-fact. No proxy
shall be valid after 11 months from the date of its execution unless otherwise
provided in the proxy.

Section Nine. Voting. Each outstanding share, regardless of class, shall be
entitled to one vote on each matter submitted to a vote at a meeting of
shareholders. The affirmative vote of the majority of shares represented at a
meeting at which a quorum is present shall be the act of the shareholders unless
the vote of a greater number or a vote by classes is required by the articles of
incorporation, these bylaws, or the laws of the State of Florida.

Section Ten. Voting Record.

(a) At least ten days before each meeting of shareholders, the secretary or
other officer of the corporation having charge of the

transfer books shall compile a complete list, in alphabetical order, of the
names and addresses of shareholders entitled to vote at such meeting, arranged
by voting group with the number and class and series, if any, of shares held by
each. The list shall be kept on file at the registered office of the corporation
and shall be subject to inspection by any shareholder during the ten days
immediately prior to such meeting, during usual business hours. The list shall
also be produced and kept open at the time and place of the meeting, and shall
be subject to the inspection of any shareholder or his or her agent or attorney
during the meeting or any adjournment.

(b) The shareholders' list shall be prima facie evidence of the identity of the
shareholders entitled to examine the shareholder's list or to vote at any
meeting of shareholders.

(c) Failure to comply with the requirements of this section shall not affect the
validity of any action taken at a meeting of shareholders. However, if the
requirements of this section have not been substantially complied with or if the
corporation refuses to allow a shareholder or his or her agent or attorney to
inspect the shareholders' list before or at the meeting, the meeting shall be
adjourned until the requirements are complied with, on the demand of any
shareholder in person or by proxy.

Section Eleven. Order of Business. The order of business at the annual meeting
of shareholders and, insofar as possible, at all other meetings of shareholders,
shall be as follows,

(a)  Call to order.

(b)  Proof of notice of meeting.

(c)  Reading and disposing of any unapproved minutes.

(d)  Reports of officers.

(e)  Reports of committees.

(f)  Election of directors.

(g)  Disposition of unfinished business.

(h)  Disposition of new business.

(i)  Adjournment.


                                   ARTICLE III

                               BOARD OF DIRECTORS

Section One. General Powers. Subject to the limitations of the articles of
incorporation, these bylaws, and the Florida Business Corporation Act concerning
corporate action that must be authorized or approved by the shareholders of the
corporation, all corporate powers shall be exercised by or under the authority
of the board of directors, and the business and affairs of the corporation shall
be managed under the direction of the board of directors.

Section Two. Number, Tenure, Qualifications, and Election. The board of
directors shall consist of not less than one person who need not be a
shareholder of the corporation. The number of directors may be increased or
decreased from time to time by

amendment to these bylaws. Directors of the corporation shall be elected at the
annual meeting of shareholders, or at a meeting held in lieu of the annual
meeting as provided in Article II, Section One, Paragraph (b), above, and shall
serve until the next succeeding annual meeting and until their successors have
been elected and qualified.

Section Three. Meetings.

(a) The board of directors shall hold an organizational meeting immediately
following each annual meeting of shareholders. Additionally, regular meetings of
the board of directors shall be held at such times as shall be fixed from time
to time by resolution of the board.

(b) Special meetings of the board may be called at any time by the president,
or, if the president is absent or is unable or refuses to act, by any
vice-president or by any two members of the board.

(c) Notice need not be given of regular meetings of the board, nor need notice
be given of adjourned meetings. Notice of special meetings shall be in writing,
delivered in person or by first-class mail or telegram or cablegram at least
two days prior to the date of the meeting. Neither the business to be transacted
nor the purpose of any such meeting need be specified in the notice. Attendance
of a director at a meeting shall constitute a waiver of notice and a waiver of
all objection to the place, time, and manner of calling the same, except where
the director states, at the beginning of the meeting, any objection to the
transaction of business because the meeting is not lawfully called or convened.

(d) Members of the board may participate in a meeting of the board by means of a
conference telephone or similar communications equipment by which all persons
participating can hear each other at the same time, and participation by such
means shall constitute presence in person at a meeting.

Section Four. Quorum and Voting. A majority of directors in office shall
constitute a quorum for the transaction of business, and the acts of a majority
of directors present at a meeting at which a quorum is present shall constitute
the acts of the board of directors. If, at any meeting of the board of
directors, less than a quorum is present, a majority of those present may
adjourn the meeting, from time to time, until a quorum is present. In the event
vacancies exist on the board of directors, other than vacancies created by the
removal of a director or directors by the shareholders or by an increase in the
number of directors, the remaining directors, although less than a quorum, may
elect a successor or successors for the unexpired term or terms by majority
vote.

Section Five. Vacancies.

(a)  A vacancy in the board of directors shall exist on the

         ----
                                        5

happening of any of the following events: (1) A director dies, resigns, or is
removed from office; (2) The authorized number of directors is increased without
the simultaneous election of a director or directors to fill the newly
authorized position. (3) The shareholders at any annual, regular, or special
meeting at which directors are to be elected, elect less than the number of
directors authorized to be elected at that meeting. (4) The board of directors
declares vacant the office of a director who has been adjudicated of unsound
mind or has been finally convicted of a felony, or who, within 10 days after
notice of his or her election to the board, neither accepts the office in
writing nor attends a meeting of the board of directors.

A reduction in the authorized number of directors does not remove any director
from office prior to the expiration of his or her term of office.

(b) A vacancy in the board of directors, except a vacancy occurring by the
removal of a director, may be filled by the vote of a majority of the remaining
directors, even though less than a quorum is present. Each director so elected
shall hold office for the unexpired term of his or her predecessor in office.
Any directorship that is to be filled as a result of an increase in the number
of directors must be filled by election at an annual or special meeting of
shareholders called for that purpose).

Section Six. Removal.

(a) At any regular meeting of shareholders, or at any special meeting called for
such purpose, any director or directors may be removed from office, with or
without cause, by majority vote.

(b) New directors may be elected by the shareholders for the unexpired terms of
directors removed from office at the same meetings at which such removals are
voted. If the shareholders fail to elect persons to fill the unexpired terms of
removed directors, such terms shall be considered vacancies to be filled by the
remaining directors as provided in Section Five, above.

Section Seven. Compensation. Directors who are not employed as officers of the
corporation or including directors also serving the corporation in another
capacity and receiving separate compensation shall be entitled to receive from
the corporation as compensation for their services as directors such reasonable
compensation as the board may from time to time determine, and shall also be
entitled to reimbursements for any reasonable expenses incurred in attending
meetings of directors.

Section Eight. Indemnification. The corporation shall indemnify any person who
was or is a party or is threatened to be made a party, to any threatened,
pending, or completed action, suit, or proceeding whether civil, criminal,
administrative, or investigative, by reason of the fact that he or she is or was
a

director or officer of the corporation, or is or was serving at the request of
the corporation as a director or officer of any other corporation, partnership,
joint venture, trust, or other enterprise, against expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlements, actually
and reasonably incurred by him or her in connection with such action, suit, or
proceeding, including any appeal of such action, if he or she acted in good
faith and in a manner he or she reasonably believed to be in or not opposed to
the best interests of the corporation and, with respect to any criminal action
or proceeding, had no reasonable cause to believe such conduct was unlawful.
However, no indemnification shall be provided in any action or suit by or in the
right of the corporation to procure a judgment in its favor, with respect to any
claim, issue, or matter as to which such person is adjudged to be liable for
negligence or misconduct in the performance of his or her duty to the
corporation. Indemnification under this section shall be made by the corporation
only as authorized in the specific case on a determination by a majority of
disinterested directors, that such individual met the applicable standard of
conduct set forth above. The termination of any action, suit, or proceeding by
judgment, order, settlement, conviction, or on a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
meet the applicable standard of conduct. Indemnification shall continue as to a
person who has ceased to be a director or officer, and shall inure to the
benefit of the heirs, executors, and administrators of such a person.


Section Nine. Committees.

(a) The board of directors may, by resolution adopted by a majority of the full
board, designate two or more directors to constitute an executive committee
which, to the extent provided in such resolution, shall have and may exercise
all of the authority of the board of directors in the management of the
corporation, except that such committee shall have no authority to (1) approve
or recommend to shareholders actions or proposals required by law to be approved
by the shareholders; (2) fill vacancies on the board of directors or any
committee; (3) adopt, amend, or repeal these bylaws; (4) authorize or approve
the reacquisition of shares, unless pursuant to a general formula or method
specified by the board of directors; or (5) authorize or approve the issuance or
sale or contract for the sale of shares, or determine the designation and
relative rights, preferences, and limitations of a voting group except where the
board of directors authorizes a committee to do so within limits specifically
prescribed by the board. The board of directors shall have power at any time to
fill vacancies in, to change the size or membership of, and to discharge any
such committee.

(b) Any such executive committee shall keep a written record of its proceedings
and shall submit such record to the whole board at each regular meeting and at
such other times as may be requested by

the board. However, failure to submit the record, or failure of the board to
approve any action indicated in the record shall not invalidate such action to
the extent it has been carried out by the corporation prior to the time the
record was or should have been submitted to the board as provided.

                                   ARTICLE IV

                                    OFFICERS

Section One. Enumeration of Offices. The corporation shall have as officers a
president, a vice-president, a secretary, and a treasurer. The board of
directors, in its discretion, may appoint a chairman of the board, one or more
additional vice-presidents, one or more assistant secretaries, one or more
assistant treasurers, and such other officers as the business of the corporation
may require.

Section Two. Election and Term of Office. The principal officers of the
corporation shall be elected by the board of directors at its organizational
meeting immediately following the annual meeting of shareholders, or as soon
afterward as is reasonably possible. Subordinate officers may be elected from
time to time as the board may see fit. Each officer shall hold office until his
or her successor is elected and qualified, or until his or her resignation,
death, or removal.

Section Three. Removal. Any officer may be removed from office at any time, with
or without cause, on the affirmative vote of a majority of the board of
directors. Removal shall be without prejudice to any contract rights of the
officer removed.

Section Four. Vacancies. Vacancies in offices, however occasioned, may be filled
by election by the board of directors at any time for the unexpired terms of
such offices.

Section Five. President; Powers and Duties. Subject to any supervisory duties
that may be given by the board of directors to any chairman of the board, the
president shall be the principle executive officer of the corporation. Subject
to the control of the board of directors, the president shall supervise and
direct generally all the business and affairs of the corporation. The president
shall preside at all meetings of shareholders at which he or she is present. In
the absence of the chairman of the board, or if there is no such chairman, the
president shall preside at all meetings of the board of directors at which he or
she is present. The president may sign, with the secretary or any other officer
of the corporation so authorized by the board of directors, certificates for
shares of the corporation, and any deeds, mortgages, bonds, contracts, or other
instruments that the board of directors has authorized for execution, except
when the signing and execution has been expressly delegated by the board of
directors or these bylaws to some other officer or agent of the corporation or
is required by law to be otherwise signed or executed. The

                               ARTICLE I.  OFFICES

          1.01. Principal and Business Offices. The corporation may have such
principal and other business offices, either within or without the State of
Wisconsin, as the Board of Directors may designate or as the business of the
corporation may require from time to time.

          1.02. Registered Office. The registered office of the corporation
required by the Wisconsin Business Corporation Law to be maintained in the State
of Wisconsin may be, but need not be, identical with the principal office in the
State of Wisconsin, and the address of the registered office may be changed
from time to time by the Board of Directors or by the registered agent. The
business office of the registered agent of the corporation shall be identical
to such registered office.

                           ARTICLE II. SHAREHOLDERS

          2.01. Annual Meeting. The annual meeting of the shareholders shall be
held at the date and hour in each year set forth in Section 0.01, or at such
other time and date within thirty days before or after said date as may be fixed
by or under the authority of the Board of Directors, for the purpose of electing
directors and for the transaction of such other business as may come before the
meeting. If the day fixed for the annual meeting shall be a legal holiday in the
State of Wisconsin, such meeting shall be held on the next succeeding business
day. If the election of directors shall not be held on the day designated
herein, or fixed as herein provided, for any annual meeting of the shareholders,
or at any adjournment thereof, the Board of Directors shall cause the election
to be held at a special meeting of the shareholders as soon thereafter as
conveniently may be.

          2.02. Special Meeting. Special meetings of the shareholders, for any
purpose or purposes, unless otherwise prescribed by statute, may be called by
the President or the Board of Directors or by the person designated in the
written request of the holders of not less than one-tenth of all shares of the
corporation entitled to vote at the meeting.


                                      B-1
<PAGE>   4

          2.03. Place of Meeting. The Board of Directors may designate any
place, either within or without the State of Wisconsin, as the place of meeting
for any annual meeting or for any special meeting called by the Board of
Directors. A waiver of notice signed by all shareholders entitled to vote at a
meeting may designate any place, either within or without the State of
Wisconsin, as the place for the holding of such meeting. If no designation is
made, or if a special meeting be otherwise called, the place of meeting shall be
the principal business office of the corporation in the State of Wisconsin or
such other suitable place in the county of such principal office as may be
designated by the person calling such meeting, but any meeting may be adjourned
to reconvene at any place designated by vote of a majority of the shares
represented thereat.

          2.04. Notice of Meeting. Written notice stating the place, day and
hour of the meeting and, in case of a special meeting, the purpose or purposes
for which the meeting is called, shall be delivered not less than the number of
days set forth in Section 0.02 (unless a longer period is required by law or the
articles of incorporation) nor more than fifty days before the date of the
meeting, either personally or by mail, by or at the direction of the President,
or the Secretary, or other officer or persons calling the meeting, to each
shareholder of record entitled to vote at such meeting. If mailed, such notice
shall be deemed to be delivered when deposited in the United States mail,
addressed to the shareholder at his address as it appears on the stock record
books of the corporation, with postage thereon prepaid.

          2.05. Closing of Transfer Books or Fixing of Record Date. For the
purpose of determining shareholders entitled to notice of or to vote at any
meeting of shareholders or any adjournment thereof, or shareholders entitled to
receive payment of any dividend, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors may provide
that the stock transfer books shall be closed for a stated period but not to
exceed, in any case, fifty days. If the stock transfer books shall be closed for
the purpose of determining shareholders entitled to notice of or to vote at a
meeting of shareholders, such books shall be

                                      B-2
<PAGE>   5

closed for at least ten days immediately preceding such meeting. In lieu of
closing the stock transfer books, the Board of Directors may fix in advance a
date as the record date for any such determination of shareholders, such date in
any case to be not more than fifty days and, in case of a meeting of
shareholders, not less than ten days prior to the date on which the particular
action, requiring such determination of shareholders, is to be taken. If the
stock transfer books are not closed and no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting of
shareholders, or shareholders entitled to receive payment of a dividend, the
close of business on the date on which notice of the meeting is mailed or on the
date on which the resolution of the Board of Directors declaring such dividend
is adopted, as the case may be, shall be the record date for such determination
of shareholders. When a determination of shareholders entitled to vote at any
meeting of shareholders has been made as provided in this section, such
determination shall be applied to any adjournment thereof except where the
determination has been made through the closing of the stock transfer books and
the stated period of closing has expired.

          2.06. Voting Records. The officer or agent having charge of the stock
transfer books for shares of the corporation shall, before each meeting of
shareholders, make a complete record of the shareholders entitled to vote at
such meeting, or any adjournment thereof, with the address of and the number of
shares held by each. Such record shall be produced and kept open at the time and
place of the meeting and shall be subject to the inspection of any shareholder
during the whole time of the meeting for the purposes of the meeting. The
original stock transfer books shall be prima facie evidence as to who are the
shareholders entitled to examine such record or transfer books or to vote at any
meeting of shareholders. Failure to comply with the requirements of this section
shall not affect the validity of any action taken at such meeting.

          2.07. Quorum. Except as otherwise provided in the articles of
incorporation, a majority of the shares entitled to vote, represented in person
or by proxy, shall constitute a quorum at a meeting of shareholders. If a quorum
is present, the affirmative vote of the majority of the shares represented at
the meeting and entitled to vote on the subject matter shall


                                      B-3
<PAGE>   6

be the act of the shareholders unless the vote of a greater number or voting by
classes is required by law or the articles of incorporation. Though less than a
quorum of the outstanding shares are represented at a meeting, a majority of the
shares so represented may adjourn the meeting from time to time without further
notice. At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified.

          2.08. Conduct of Meetings. The President, and in his absence, a
Vice-President in the order provided under Section 4.06, and in their absence,
any person chosen by the shareholders present shall call the meeting of the
shareholders to order and shall act as chairman of the meeting, and the
Secretary of the corporation shall act as secretary of all meetings of the
shareholders, but, in the absence of the Secretary, the presiding officer may
appoint any other person to act as secretary of the meeting.

          2.09. Proxies. At all meetings of shareholders, a shareholder entitled
to vote may vote in person or by proxy appointed in writing by the shareholder
or by his duly authorized attorney in fact. Such proxy shall be filed with the
Secretary of the corporation before or at the time of the meeting. Unless
otherwise provided in the proxy, a proxy may be revoked at any time before it is
voted, either by written notice filed with the Secretary or the acting secretary
of the meeting or by oral notice given by the shareholder to the presiding
officer during the meeting. The presence of a shareholder who has filed his
proxy shall not of itself constitute a revocation. No proxy shall be valid after
eleven months from the date of its execution, unless otherwise provided in the
proxy. The Board of Directors shall have the power and authority to make rules
establishing presumptions as to the validity and sufficiency of proxies.

          2.10. Voting of Shares. Each outstanding share shall be entitled to
one vote upon each matter submitted to a vote at a meeting of shareholders,
except to the extent that the voting rights of the shares of any class or
classes are enlarged, limited or denied by the articles of incorporation.

          2.11. Voting of Shares by Certain Holders.

<PAGE>   7

               (a) Other Corporations. Shares standing in the name of another
          corporation may be voted either in person or by proxy, by the
          president of such corporation or any other officer appointed by such
          president. A proxy executed by any principal officer of such other
          corporation or assistant thereto shall be conclusive evidence of the
          signer's authority to act, in the absence of express notice to this
          corporation, given in writing to the Secretary of this corporation, of
          the designation of some other person by the board of directors or the
          by-laws of such other corporation.

               (b) Legal Representatives and Fiduciaries. Shares held by an
          administrator, executor, guardian, conservator, trustee in bankruptcy,
          receiver, or assignee for creditors may be voted by him, either in
          person or by proxy, without a transfer of such shares into his name,
          provided that there is filed with the Secretary before or at the time
          of meeting proper evidence of his incumbency and the number of shares
          held. Shares standing in the name of a fiduciary may be voted by him,
          either in person or by proxy. A proxy executed by a fiduciary, shall
          be conclusive evidence of the signer's authority to act, in the
          absence of express notice to this corporation, given in writing to the
          Secretary of this corporation, that such manner of voting is expressly
          prohibited or otherwise directed by the document creating the
          fiduciary relationship.

               (c) Pledgees. A shareholder whose shares are pledged shall be
          entitled to vote such shares until the shares have been transferred
          into the name of the pledgee, and thereafter the pledgee shall be
          entitled to vote the shares so transferred.

               (d) Treasury Stock and Subsidiaries. Neither treasury shares, nor
          shares held by another corporation if a majority of the shares
          entitled to vote for the election of directors of such other
          corporation is held by this corporation, shall be voted at any meeting
          or counted in determining the total number of outstanding shares
          entitled to vote, but shares of its own issue held by this corporation
          in a fiduciary capacity, or held by such other corporation in a
          fiduciary capacity, may be voted and shall be counted in determining
          the total number of outstanding shares entitled to vote.

               (e) Minors. Shares held by a minor may be voted by such minor in
          person or by proxy and no such vote shall be subject to disaffirmance
          or avoidance, unless prior to such vote the Secretary of the
          corporation has received written notice or has actual knowledge that
          such shareholder is a minor.

               (f) Incompetents and Spendthrifts. Shares held by an incompetent
          or spendthrift may be voted by such incompetent or spendthrift in
          person or by proxy and no such vote shall be subject to disaffirmance
          or avoidance, unless prior to such vote the Secretary of the
          corporation has actual knowledge that such shareholder has been
          adjudicated an incompetent or spendthrift or actual knowledge of
          filing of judicial proceedings for appointment of a guardian.

               (g) Joint Tenants. Shares registered in the names of two or more
          individuals who are named in the registration as joint tenants may be
          voted in person or by proxy signed by any one or more of such
          individuals if either (i) no other such individual or his legal
          representative is present and claims the right to participate in the
          voting of such shares or prior to the vote files with the Secretary
          of the corporation a contrary written voting authorization or
          direction or written denial of authority of the individual present or
          signing the proxy proposed to be voted or (ii) all such other
          individuals are deceased and the Secretary of the corporation has no
          actual knowledge that the survivor has been adjudicated not to be the
          successor to the interests of those deceased.

          2.12. Waiver of Notice by Shareholders. Whenever any notice whatever
is required to be given to any shareholder of the corporation under the articles
of incorporation or by-laws or any provision of law, a waiver thereof in
writing, signed at any time, whether before or after the time of meeting, by the
shareholder entitled to such notice, shall be deemed equivalent to the giving of
such notice; provided that such waiver in respect to any matter of which notice
is required under any provision of the Wisconsin


                                      B-6
<PAGE>   9

Business Corporation Law, shall contain the same information as would have been
required to be included in such notice, except the time and place of meeting.

          2.13. Unanimous Consent without Meeting. Any action required or
permitted by the articles of incorporation or by-laws or any provision of law
to be taken at a meeting of the shareholders, may be taken without a meeting if
a consent in writing, setting forth the action so taken, shall be signed by all
of the shareholders entitled to vote with respect to the subject matter thereof.

                         ARTICLE III.  BOARD OF DIRECTORS

          3.01. General Powers and Number. The business and affairs of the
corporation shall be managed by its Board of Directors. The number of
directors of the corporation shall be as provided in Section 0.03.

          3.02. Tenure and Qualifications. Each director shall hold office until
the next annual meeting of shareholders and until his successor shall have been

shareholders called for that purpose. A director may resign at any time by
filing his written resignation with the Secretary of the corporation. Directors
need not be residents of the State of Wisconsin or shareholders of the
corporation.

          3.03. Regular Meetings. A regular meeting of the Board of Directors

that number of hours prior thereto as set forth in Section 0.04. If mailed, such
notice shall be deemed to be delivered when deposited in the United States mail
so addressed, with postage thereon prepaid. If notice be given by telegram, such
notice shall be deemed to be delivered when the telegram is delivered to the
telegraph company. Whenever any notice whatever is required to be given to any
director of the corporation under the articles of incorporation or by-laws or
any provision of law, a waiver thereof in writing, signed at any time, whether
before or after the time of meeting, by the director entitled to such notice,
shall be deemed equivalent to the giving of such notice. The attendance of a
director at a meeting shall constitute a waiver of notice of such meeting,
except where a director attends a meeting and objects thereat to the transaction
of any business because the meeting is not lawfully called or convened. Neither
the business to be transacted at, nor the purpose of, any regular or special
meeting of the Board of Directors need be specified in the notice or waiver of
notice of such meeting.

time to time without further notice.

          3.07. Manner of Acting. The act of the majority of the directors
present at a meeting at which a quorum is present shall be the act of the Board
of Directors, unless


                                      B-8
<PAGE>   11
the act of a greater number is required by law or by the articles of
incorporation or these by-laws.

          3.08. Conduct of Meetings. The President, and in his absence, a
Vice-President in the order provided under Section 4.06, and in their absence,
any director chosen by the directors present, shall call meetings of the Board
of Directors to order and shall act as chairman of the meeting. The Secretary of
the corporation shall act as secretary of all meetings of the Board of
Directors, but in the absence of the Secretary, the presiding officer may
appoint any Assistant Secretary or any director or other person present to act
as secretary of the meeting.

including a vacancy created by an increase in the number of directors, may be
filled until the next succeeding annual election by the affirmative vote of a
majority of the directors then in office, though less than a quorum of the Board
of Directors; provided, that in case of a vacancy created by the removal of a
director by vote of the shareholders, the shareholders shall have the right to
fill such vacancy at the same meeting or any adjournment thereof.

          3.10. Compensation. The Board of Directors, by affirmative vote of a
majority of the directors then in office, and irrespective of any personal
interest of any of its members, may establish reasonable compensation of all
directors for services to the corporation as directors, officers or otherwise,

Directors also shall have authority to provide for or to delegate authority to
an appropriate committee to provide for reasonable pensions, disability or death
benefits, and other benefits or payments, to directors, officers and employees
and to their estates, families, dependents or beneficiaries on account of prior
services rendered by such directors, officers and employees to the corporation.

present at a meeting of the Board of Directors or a committee thereof of which
he is a member at which action on any corporate matter is taken shall be


                                      B-9
<PAGE>   12

presumed to have assented to the action taken unless his dissent shall be
entered in the minutes of the meeting or unless he shall file his written
dissent to such action with the person acting as the secretary of the meeting
before the adjournment thereof or shall forward such dissent by registered mail
to the Secretary of the corporation immediately after the adjournment of the
meeting. Such right to dissent shall not apply to a director who voted in favor
of such action.

          3.12. Committees. The Board of Directors by resolution adopted by the
affirmative vote of a majority of the number of directors as provided in Section
0.03 may designate one or more committees, each committee to consist of three or
more directors elected by the Board of Directors, which to the extent provided
in said resolution as initially adopted, and as thereafter supplemented or
amended by further resolution adopted by a like vote, shall have and may
exercise, when the Board of Directors is not in session, the powers of the Board
of Directors in the management of the business and affairs of the corporation,
except action in respect to dividends to shareholders, election of the principal
officers or the filling of vacancies in the Board of Directors or committees
created pursuant to this section. The Board of Directors may elect one or more
of its members as alternate members of any such committee who may take the place
of any absent member or members at any meeting of such committee, upon request
by the President or upon request by the chairman of such meeting. Each such
committee shall fix its own rules governing the conduct of its activities and
shall make such reports to the Board of Directors of its activities as the Board
of Directors may request.

          3.13. Unanimous Consent without Meeting. Any action required or
permitted by the articles of incorporation or by-laws or any provision of law to
be taken by the Board of Directors at a meeting or by resolution may be taken
without a meeting if a consent in writing, setting forth the action so taken,
shall be signed by all of the directors then in office.

             ARTICLE VI.  CERTIFICATES FOR SHARES AND THEIR TRANSFER

          6.01. Certificates for Shares. Certificates representing shares of the
corporation shall be in such form, consistent with law, as shall be determined
by the Board of Directors. Such certificates shall be signed by the President or
a Vice-President and by the Secretary or an Assistant Secretary. All
certificates for shares shall be consecutively numbered or otherwise identified.
The name and address of the person to whom the shares represented thereby are
issued, with the number of shares and date of issue, shall be entered on the
stock transfer books of the corporation. All certificates surrendered to the
corporation for transfer shall be cancelled and no new certificate shall be
issued until the former certificate for a like number of shares shall have been
surrendered and cancelled, except as provided in Section 6.06.

          6.02. Facsimile Signatures and Seal. The seal of the corporation on
any certificates for shares may be a facsimile. The signatures of the President
or Vice-President and the Secretary or Assistant Secretary upon a certificate
may be facsimiles if the certificate is manually signed on behalf of a
transfer agent, or a registrar, other than the corporation itself or an employee
of the corporation.

          6.03. Signature by Former Officers. In case any officer, who has
signed or whose facsimile signature has been placed upon any certificate for
shares, shall have ceased to be such officer before such certificate is issued,
it may be issued by the corporation with the same effect as if he were such

          6.04. Transfer of Shares. Prior to due presentment of a certificate
for shares for registration of transfer the corporation may treat the registered
owner of such shares as the person exclusively entitled to vote, to receive
notifications and otherwise to have and exercise all the rights and power of an
owner. Where a certificate for shares is presented to the corporation with a
request to register for transfer, the corporation shall not be liable to the
owner or any other person suffering loss as a result of such registration of
transfer


                                      B-16
<PAGE>   19


if (a) there were on or with the certificate the necessary endorsements, and (b)
the corporation had no duty to inquire into adverse claims or has discharged any
such duty. The corporation may require reasonable assurance that said
endorsements are genuine and effective and compliance with such other
regulations as may be prescribed by or under the authority of the Board of
Directors.

          6.05. Restrictions on Transfer. The face or reverse side of each
certificate representing shares shall bear a conspicuous notation of any
restriction imposed by the corporation upon the transfer of such shares.

          6.06. Lost, Destroyed or Stolen Certificates. Where the owner claims
that his certificate for shares has been lost, destroyed or wrongfully taken, a
new certificate shall be issued in place thereof if the owner (a) so requests
before the corporation has notice that such shares have been acquired by a bona
fide purchaser, and (b) files with the corporation a sufficient indemnity bond,
and (c) satisfies such other reasonable requirements as may be prescribed by or
under the authority of the Board of Directors.

          6.07. Consideration for Shares. The shares of the corporation may be
issued for such consideration as shall be fixed from time to time by the Board
of Directors, provided that any shares having a par value shall not be issued
for a consideration less than the par value thereof. The consideration to be
paid for shares may be paid in whole or in part, in money, in other property,
tangible or intangible, or in labor or services actually performed for the
corporation. When payment of the consideration for which shares are to be issued
shall have been received by the corporation, such shares shall be deemed to be
fully paid and nonassessable by the corporation. No certificate shall be issued
for any share until such share is fully paid.

          6.08. Stock Regulations. The Board of Directors shall have the power
and authority to make all such further rules and regulations not inconsistent
with the statutes of the State of Wisconsin as it may deem expedient concerning
the issue, transfer and registration of certificates representing shares of the
corporation.

          owes to the corporation and the breach or failure to perform
          constitutes any of the following:

          lawful or no reasonable cause to believe that his or her conduct was
          unlawful.

                         (3) A transaction from which the director or officer
          derived improper personal profit.

                         (4) Willful misconduct.

               (c) Pursuant to Section 180.044 of the Wisconsin Statutes, the
          determination of whether indemnification is required under this

specifically defined in the Wisconsin Business Corporation Law as amended

                      TRANSACTIONS WITH INTERESTED PARTIES

     The corporation may enter into contracts and otherwise transact any
business with its directors, officers, and shareholders, and with any entity in
which they may have an interest adverse to the corporation, as freely as though
such adverse interest does not exist, even though the vote, action or presence
of such director, officer or shareholder may be necessary to obligate the
corporation upon such contracts or transactions.

     In the absence of fraud, and with the notice required by the following
paragraph, no such contract or transaction shall be avoided and no such
director, officer or shareholder shall be held liable to account to the
corporation, by reason of such adverse interest or by reason of any fiduciary
relationship to the corporation, for any profit or benefit realized by him
through any such contract or transaction.

     Directors and officers of the corporation shall notify the Board of
Directors, at the meeting at which such contract or transaction is authorized or
confirmed, of the nature of their adverse interest. A general notice that a
director or officer of the corporation is interested in any entity shall be
sufficient disclosure of such adverse interest. No notice shall be required if
all directors have actual knowledge of the adverse interest.

     The undersigned, president and secretary of DAS-CO of Idaho, Inc., hereby
certify that the above Amended and Restated Articles of Incorporation were
adopted by resolution of the board of directors, and were approved by the
shareholders on March 1, 1995, as follows:

shareholders for any other proper purpose, the board of directors may provide
that the share transfer books shall be closed for a stated period not exceeding
fifty (50) days. If the stock transfer books shall be closed for the purpose of
determining shareholders entitled to notice of or to vote at a meeting of
shareholders, such books shall be closed for at least ten (10) days immediately
preceding such meeting. In lieu of closing the stock transfer books, the by-laws

advance a date as the record date for any such determination of shareholders,
not later than fifty (50) days and, in case of a meeting of shareholders, not

or the by-laws.

shares of the corporation shall make, at least ten (10) days before each meeting

direction of the president or the secretary or the officer or person calling the

time and place of meeting, no notice thereof shall be required, and any such
meeting (whether annual, regular or special) shall be held at the time and at
the place (either within or without the State of Texas) specified in the waiver

a transfer agent or a registrar, other than the corporation itself or an
employee of the corporation, the signatures of any such officer may be
facsimile. In case any officer or officers who shall have signed or whose
facsimile signature or signatures shall have been used on any such certificate
or certificates shall cease to be such officer or officers of the corporation,
whether because of death, resignation or otherwise, before said certificate or
certificates shall have been issued, such certificate may nevertheless be issued
by the corporation with the same effect as though the person or persons who

Certificates shall be in such form as shall in conformity to law be prescribed
from time to time by the board of directors.

the old certificate, and record the transaction upon its books.

3.   REGISTERED SHAREHOLDERS

     The corporation shall be entitled to treat the holder of record of any
share or shares of stock as the holder in fact thereof and, accordingly shall
not be bound to recognize any equitable or other claim to or interest in such
share on the part of any other person, whether or not it shall have express or
other notice thereof, except as otherwise provided by law.

4.   LOST CERTIFICATE

     The board of directors may direct a new certificate or certificates to be
issued in place of any certificate or certificates theretofore issued by the
corporation alleged to have been lost or destroyed, upon the making of an
affidavit of that fact by the person claiming the certificate to be lost. When
authorizing such issue of a new certificate or certificates, the board of
directors in its discretion and as a condition precedent to the issuance
thereof, may require the owner of such lost or destroyed certificate or
certificates or his legal representative to advertise the same in such manner as
it shall require or to give the corporation a bond with surety and in form
satisfactory to the corporation (which bond shall also name the corporation's
transfer agents and registrars, if any, as obligees) in such sum as it may
direct as indemnity against any claim that may be made against the corporation
or other obligees with respect to the certificate alleged to have been

                                    by-laws 9

2.   RESERVES

     Before payment of any dividend there may be set aside out of any funds of
the corporation available for dividends such sum or sums as the directors from
time to time in their absolute discretion think proper as a reserve fund to meet
contingencies or for equalizing dividends or for repairing or maintaining any
property of the corporation or for such other purpose as the directors shall
think conducive to the interest of the corporation, and the directors may
abolish any such reserve in the manner in which it was created.

     Any action required to be taken or which may be taken at a meeting of the

without a meeting if a consent in writing setting forth the action so taken
shall be signed by all of the shareholders, directors, or members of the
executive committee, as the case may be, entitled to vote with respect to the
subject matter thereof, and such consent shall have the same force and effect as

6.   CLOSE CORPORATIONS: MANAGEMENT BY SHAREHOLDERS

     If the articles of incorporation of the corporation and each certificate
representing its issued and outstanding shares states that the business and
affairs of the corporation shall be managed by the shareholders of the
corporation rather than by a board of directors, then, whenever the context so
requires the shareholders of the corporation shall be deemed the directors of
the corporation for purposes of applying any provision of these by-laws.

7.   AMENDMENTS

     These by-laws may be altered, amended or repealed in whole or in part by
the affirmative vote of the holders of a majority of the shares outstanding and
entitled to vote, but such power may be delegated by the shareholders to the
board of directors.

suit, proceeding or claim asserted against such director or officer (including

counsel selected by such Board of Directors or committee. The right to
indemnification herein provided shall not be exclusive of any other rights to
which such director or officer may be lawfully entitled.

           The principal office of the corporation in the State of Missouri
shall be located in the City of Union County of Franklin. The corporation may
have such other offices, either within or without the State of incorporation as
the board of directors may designate or as the business of the corporation may
from time to time require.



                           ARTICLE II -- STOCKHOLDERS


1.     ANNUAL MEETING.

           The annual meeting of the stockholders shall be held on the 2nd
Tuesday of December in each year, beginning with the year 1983 at the hour 9:00
o'clock A.M., for the purpose of electing directors and for the transaction of
such other business as may come before the meeting. If the day fixed for the
annual meeting shall be a legal holiday such meeting shall be held on the next
succeeding business day.

2.     SPECIAL MEETINGS.

           Special meetings of the stockholders, for any purpose or purposes,
unless otherwise prescribed by statute, may be called by the president or by
the directors, and shall be called by the president at the request of the
holders of not less than 2/3 per cent of all the outstanding shares of the
corporation entitled to vote at the meeting.

3.     PLACE OF MEETING.

           The directors may designate any place, either within or without the
State unless otherwise prescribed by statute, as the place of meeting for any
annual meeting or for any special meeting called by the directors. A waiver of
notice signed by all stockholders entitled to vote at a meeting may designate



                                   By-Laws 1



<PAGE>   2



any place, either within or without the state unless otherwise prescribed by
statute, as the place for holding such meeting. If no designation is made, or if
a special meeting be otherwise called, the place of meeting shall be the
principal office of the corporation.

4.     NOTICE OF MEETING.

           Written or printed notice stating the place, day and and hour of the
meeting and, in case of a special meeting, the purpose or purposes for which
the meeting is called, shall be delivered not less than ten nor more than fifty
days before the date of the meeting, either personally or by mail, by or at the
direction of the president, or the secretary, or the officer or persons calling
the meeting, to each stockholder of record entitled to vote at such meeting. If
mailed, such notice shall be deemed to be delivered when deposited in the
United States mail, addressed to the stockholder at his address as it appears
on the stock transfer books of the corporation, with postage thereon prepaid.

5.     CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE.

          For the purpose of determining stockholders entitled to notice of or
to vote at any meeting of stockholders or any adjournment thereof, or
stockholders entitled to receive payment of any dividend, or in order to make a
determination of stockholders for any other proper purpose, the directors of
the corporation may provide that the stock transfer books shall be closed for a
stated period but not to exceed, in any case, fifty days. If the stock transfer
books shall be closed for the purpose of determining stockholders entitled to
notice of or to vote at a meeting of stockholders, such books shall be closed
for at least ten days immediately preceding such meeting. In lieu of closing
the stock transfer books, the directors may fix in advance a date as the record
date for any such determination of stockholders, such date in any case to be
not more than fifty days and, in case of a meeting of stockholders, not less
than ten days prior to the date on which the particular action requiring such
determination of stockholders is to be taken. If the stock transfer books are
not closed and no record date is fixed for the determination of stockholders
entitled to notice of or to vote at a meeting of stockholders, or stockholders
entitled to receive payment of a dividend, the date on which notice of the
meeting is mailed or the date on which the resolution of the directors
declaring such dividend is adopted, as the case may be, shall be the record
date for such determination of stockholders. When a determination of
stockholders entitled to vote at any meeting of stockholders



                                   By-Laws 2




<PAGE>   3



has been made as provided in this section, such determination shall apply to
any adjournment thereof.

shares of the corporation shall make, at least ten days before each meeting of
stockholders, a complete list of the stockholders entitled to vote at such
meeting, or any adjournment thereof, arranged in alphabetical order, with the
address of and the number of shares held by each, which list, for a period of
ten days prior to such meeting, shall be kept on file at the principal office
of the corporation and shall be subject to inspection by any stockholder at any
time during usual business hours. Such list shall also be produced and kept
open at the time and place of the meeting and shall be subject to the
inspection of any stockholder during the whole time of the meeting. The
original stock transfer book shall be prima facie evidence as to who are the
stockholders entitled to examine such list or transfer books or to vote at the
meeting of stockholders.

7.     QUORUM.

           At any meeting of stockholders the majority of the outstanding shares
of the corporation entitled to vote, represented in person or by proxy, shall
constitute a quorum at a meeting of stockholders. If less than said number of
the outstanding shares are represented at a meeting, a majority of the shares so
represented may adjourn the meeting from time to time without further notice. At
such adjourned meeting at which a quorum shall be present or represented, any
business may be transacted which might have been transacted at the meeting as
originally notified. The stockholders present at a duly organized meeting may
continue to transact business until adjournment, notwithstanding the withdrawal
of enough stockholders to leave less than a quorum.

8.      PROXIES.

           At all meetings of stockholders, a stockholder may vote by proxy
executed in writing by the stockholder or by his duly authorized attorney in
fact. Such proxy shall be filed with the secretary of the corporation before or
at the time of the meeting.

the demand of any stockholder, the vote for directors and upon any question
before the meeting shall be by ballot. All elections for directors shall be
decided by plurality vote; all other questions shall be decided by majority
vote except as otherwise provided by the Certificate of Incorporation or the
laws of this State.

10.    ORDER OF BUSINESS.

          The order of business at all meetings of the stockholders, shall be

          7.     Unfinished Business.

          8.     New Business.

           Unless otherwise provided by law, any action required to be taken at
a meeting of the shareholders, or any other action which may be taken at a
meeting of the shareholders, may be taken without a meeting if a consent in
writing, setting forth the action so taken, shall be signed by all of the
shareholders entitled to vote with respect to the subject matter thereof.

deemed to be delivered when deposited in the United States mail so addressed,
with postage thereon prepaid. If notice be given by telegram, such notice shall
be deemed to be delivered when the telegram is delivered to the telegraph

           (a) Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, and cancel the old certificate; every such transfer shall be entered
on the transfer book of the corporation which shall be kept at its principal
office.

           (b) The corporation shall be entitled to treat the holder of record
of any share as the holder in fact thereof, and, accordingly, shall not be
bound to recognize any equitable or other claim to or interest in such share on
the part of any other person whether or not it shall have express or other
notice thereof, except as expressly provided by the laws of this state.



                           ARTICLE VII -- FISCAL YEAR

           The directors shall provide a corporate seal which shall be circular
in form and shall have inscribed thereon the name of the corporation, the state

                          ARTICLE X -- WAIVER OF NOTICE




           Unless otherwise provided by law, whenever any notice is required to
be given to any stockholder or director of the corporation under the provisions
of these by-laws or under the provisions of the articles of incorporation, a
waiver thereof in writing, signed by the person or persons entitled to such
notice, whether before or after the time stated therein, shall be deemed
equivalent to the giving of such notice.

                            ARTICLE XI -- AMENDMENTS


           These by-laws may be altered, amended or repealed and new by-laws may

special stockholders' meeting when the proposed amendment has been set out in

                                     ******

         The undersigned, COPENHAGEN UTILITIES AND CONSTRUCTION, INC., an Oregon
corporation, pursuant to resolution duly adopted by its Directors on July 1,
1997, hereby amends and restates its articles of incorporation, in their
entirety, to (1) change the corporate name; (2) clarify the capital structure
and voting rights of shareholders; (3) prevent cumulative voting of shares; (4)
modify the provisions for indemnification and limited liability of directors;
(5) allow transactions with interested parties under certain conditions; and (6)
provide for future modification of the bylaws and the articles of incorporation,
as follows:

                                    ARTICLE I

                               NAME OF CORPORATION

                                   ARTICLE II

                             DURATION OF CORPORATION

     The duration of this corporation shall be perpetual.

                                CORPORATE PURPOSE

     The purposes for which the corporation is organized are to carry on any
lawful business for which corporations may be organized under O.R.S. Chapter 57
and to exercise all powers granted to a corporation formed under that Act,
including any amendments thereto or successor statute that may be hereinafter
enacted.

                                   ARTICLE IV

                                 CAPITALIZATION


     The aggregate number of shares this corporation shall have the authority to
issue shall be:

     (a)  10,000 shares of non-assessable voting common stock having a par value
          of $.02 per share; and

     (b)  90,000 shares of non-assessable nonvoting common stock having a par
          value of $.02 per share.

<PAGE>   2





         Each share of voting common stock and each share of nonvoting common
stock shall be identical in interest. Neither voting nor nonvoting shares shall
have any preferential or superior rights; provided, however, that a voting share
shall entitle the holder thereof to vote in accordance with the provisions of
Oregon Revised Statutes, Chapter 60. The voting and nonvoting shares shall
constitute one class of shares as defined in Sections 1361(b)(1)(D) and
2701(a)(2)(B) of the Internal Revenue Code. Notwithstanding the above, each
holder of nonvoting common stock shall nonetheless have one vote per share
standing in the name of such holder on the relevant record date (and a
fractional vote for any fractional share) concerning any amendment to articles
of incorporation if the amendment would have any of the effects or cause any of
the changes described by O.R.S. Section 60.441 or otherwise effect a reduction
of or limitation upon any other preference or right accorded to the holder of
such stock as such.

                                    ARTICLE V

                              NO PREEMPTIVE RIGHTS

         The owners of shares of voting and nonvoting common stock of the
corporation shall not be entitled to preemptive rights to subscribe for or
purchase any part of new or additional issues of stock or securities convertible
into stock of any class whatsoever whether now or hereafter authorized, and
whether issued for cash, property, services, by way of dividend or otherwise.

                                   ARTICLE VI

                             NO CUMULATIVE VOTING

         There shall be no cumulative voting of shares.

                                   ARTICLE VII

                     AMENDMENT OF ARTICLES OF INCORPORATION

         The corporation reserves the right to amend, alter, change or repeal
any provisions contained in its articles of incorporation in any manner now or
hereafter prescribed or permitted by statute. All rights of shareholders of the
corporation are granted subject to this reservation.

                                  ARTICLE VIII

                               BOARD OF DIRECTORS

than seven. The actual number may be set from time to time by the board of
directors.

                               AMENDMENT OF BYLAWS

         The Board of Directors is expressly authorized to alter, amend or
repeal the bylaws of the corporation and to adopt new bylaws, subject to repeal
or change by majority vote of the shareholders. Nothing herein shall deny the
concurrent power of the shareholders to adopt, alter, amend or repeal the
bylaws.


                                    ARTICLE X
                          LIMITATION ON DIRECTOR LIABILITY

         To the fullest extent permitted by Oregon law and subject to the bylaws
of this corporation, a director of this corporation shall not be liable to the
corporation or its shareholders for monetary damages for his or her conduct as a
director. Any amendment to or repeal of this Article shall not adversely affect
any right of a director of this corporation hereunder with respect to any acts
or omissions of the director occurring prior to amendment or repeal.

                                   ARTICLE XI

                                 INDEMNIFICATION

         To the fullest extent permitted by its bylaws and Oregon law, this
corporation is authorized to indemnify any of its officers, directors, employees
and agents. The Board of Directors shall be entitled to determine the terms of
indemnification, including advance of expenses, and to give effect thereto
through the adoption of bylaws, approval of agreements, or by any other manner
approved by the Board of Directors. Any amendment to or repeal of this Article
shall not adversely affect any right of an individual with respect to any right
to indemnification arising prior to such amendment or repeal.

                                   ARTICLE XII

                      TRANSACTIONS WITH INTERESTED PARTIES

         The corporation may enter into contracts and otherwise transact any
business with its directors, officers, and shareholders, and with any entity in
which they may have an interest adverse to the corporation, as freely as though
such adverse interest does not exist, even though the vote, action or presence
of such director, officer or shareholder may be necessary to obligate the
corporation upon such contracts or transactions.

         In the absence of fraud, and with the notice required by the following
paragraph, no such contract or transaction shall be avoided and no such
director, officer or shareholder shall be held liable to account to the
corporation, by reason of such adverse interest or by reason of any fiduciary
relationship to the corporation, for any profit or benefit realized by him
through any such contract or transaction.

         Directors and officers of the corporation shall notify the Board of
Directors, at the meeting at which such contract or transaction is authorized or
confirmed, of the nature of their adverse interest. A general notice that a
director or officer of the corporation is interested in any entity shall be
sufficient disclosure of such adverse interest. No notice shall be required if
all directors have actual knowledge of the adverse interest.

         The undersigned, president of COPENHAGEN UTILITIES & CONSTRUCTION,
INC., hereby certify that the above Amended and Restated Articles of
Incorporation were adopted by resolution of the board of directors, and were
approved by the shareholders on July 1, 1997, as follows:

                    COPENHAGEN UTILITIES & CONSTRUCTION, INC.


                              ********************

     Pursuant to resolution of the Board of Directors held July 1, 1997, the
Bylaws of this Corporation are hereby amended and restated in their entirety, as
follows:

                                    SECTION I

                     SHAREHOLDERS AND SHAREHOLDERS' MEETINGS

     1.1  ANNUAL MEETING. The annual meeting of the shareholders of this
corporation (the "Corporation") for the election of directors and for the
transaction of such other business as may properly come before the meeting
shall be held each year at the principal office of the Corporation, or at some
other place either within or without the State of Oregon as designated by the
Board of Directors, on the second Monday of September each year at 9:00 a.m. or
on such other day and time as may be set by the Board of Directors.

     1.2  SPECIAL MEETINGS. Special meetings of the shareholders for any purpose
or purposes may be called at any time by the Board of Directors, the Chairman of
the Board, the President, a majority of the Board of Directors, or any
shareholder or shareholders holding in the aggregate one-tenth of the voting
power of all shareholders. The meetings shall be held at such time and place as
the Board of Directors may prescribe, or, if not held upon the request of the
Board of Directors, at such time and place as may be established by the
President or by the Secretary in the President's absence. Only business within
the purpose or purposes described in the meeting notice may be conducted.

     1.3  NOTICE OF MEETINGS. Written notice of the place, date and time of the
annual shareholders' meeting and written notice of the place, date, time and
purpose or purposes of special shareholders' meetings shall be delivered not
less than ten (10) or more than sixty (60) days before the date of the meeting,
either personally, by mail, or in any other manner approved by law, by or at the
direction of the President, the Secretary, or the officer or persons calling the
meeting, to each shareholder of record entitled to notice of such meeting.
Mailed notices shall be deemed to be delivered when deposited in the mail,
first-class postage prepaid, correctly addressed to the shareholder's address
shown in the Corporation's current record of shareholders.

     1.4  WAIVER OF NOTICE. Except where expressly prohibited by law or the
Articles of Incorporation, notice of the place, date, time and purpose or
purposes of any shareholders' meeting may be waived in a signed writing
delivered to the Corporation by any shareholder at any time, either before or
after the meeting. Attendance at the meeting in person or by proxy waives

<PAGE>   2

objection to lack of notice or defective notice of the meeting unless the
shareholder at the beginning of the meeting objects to holding the meeting or
transacting business at the meeting. A shareholder waives objection to
consideration of a particular matter at a meeting that is not within the purpose
or purposes described in the meeting notice, unless the shareholder objects to
considering the matter when it is presented.

     1.5  SHAREHOLDERS' ACTION WITHOUT A MEETING. The shareholders may take any
action without a meeting that they could properly take at a meeting, if a
written consent setting forth the action so taken is signed by all of the
shareholders entitled to vote with respect to the subject matter and is
delivered to the Corporation for inclusion in the minutes or filing with the
corporate records. If required by Oregon law, all nonvoting shareholders must be
given written notice of the proposed action at least ten days before the action
is taken, unless such notice is waived in a manner consistent with these Bylaws.
Actions taken under this section are effective when the duly signed consent is
in the possession of the Corporation, unless otherwise specified in the consent.
A shareholder may withdraw consent only by delivering a written notice of
withdrawal to the Corporation prior to the time that the duly signed consent is
in the possession of the Corporation.

     1.6  LIST OF SHAREHOLDERS. At least ten days before any shareholders'
meeting, the Secretary of the Corporation or the agent having charge of the
stock transfer books of the Corporation shall have compiled a complete list of
the shareholders entitled to notice of a shareholders' meeting, arranged in
alphabetical order and by voting group, with the address of each shareholder and
the number, class, and series, if any, of shares owned by each. The Secretary
shall have this list available for inspection at each meeting and adjournment
thereof.

     1.7  QUORUM AND VOTING. The presence in person or by proxy of the holders
of a majority of the votes entitled to be cast on a matter at a meeting shall
constitute a quorum of shareholders for that matter. If a quorum exists, action
on a matter shall be approved by a voting group upon the affirmative votes of a
majority of the shares represented at the meeting and entitled to vote upon the
subject matter, unless a greater number of affirmative votes is required by the
Articles of Incorporation or by law. If the Articles of Incorporation or Oregon
law provide for voting by two or more voting groups on a matter, action on a
matter is taken only when voted upon by each of those voting groups counted
separately. Action may be taken by one voting group on a matter even though no
action is taken by another voting group.

     1.8  ADJOURNED MEETINGS. If a shareholders' meeting is adjourned to a
different place, date or time, whether for failure to achieve a quorum or
otherwise, notice need not be given of the new place, date or time if the new
place, date or time is announced at the meeting before adjournment. When a
determination of shareholders entitled to vote at any meeting of shareholders
has been made as provided in these Bylaws, that determination shall apply to any
adjournment thereof, unless Oregon law requires fixing a new record date. If
Oregon law requires that a new record date be set for the adjourned meeting,
notice of the adjourned meeting must be given to shareholders as of the new
record date. Any business may be transacted at an adjourned meeting that could
have been transacted at the meeting as originally called.

<PAGE>   3







     1.9  PROXIES. A shareholder may appoint a proxy to vote or otherwise act
for the shareholder by signing an appointment form, either personally or by an
agent. No appointment shall be valid after 11 months from the date of its
execution unless the appointment form expressly so provides. An appointment of a
proxy is revocable unless the appointment is coupled with an interest. No
revocation shall be effective until written notice thereof has actually been
received by the Secretary of the Corporation or any other person authorized to
tabulate votes.

     1.10 RIGHTS OF NON-VOTING SHARES. If authorized in the Articles of
Incorporation, the corporation may issue shares of non-voting stock. Except to
the extent required by Oregon law, holders of non-voting stock may not vote
those shares upon any matter that may come before shareholders, including,
without limitation, the election of directors and approval of changes to the
Articles of Incorporation.

     If the corporation has more than one class of shares outstanding, the
affirmative vote of a majority of shares of each affected class, regardless of
whether any particular class is otherwise non-voting, is required to approve any
amendment to the articles of incorporation that would:

     (a)  Increase or decrease the aggregate number of authorized shares of such
          class;

     (b)  Increase or decrease the par value of the shares of such class;

     (c)  Effect an exchange, reclassification or cancellation of all or part of
          the shares of such class;

     (d)  Effect an exchange, or create a right of exchange, of all or part of
          the shares of another class into the shares of such class;

     (e)  Change the designations, preferences, limitations or relative rights
          of the shares of such class;

     (f)  Change the shares of such class, whether with or without par value,
          into the same or a different number of shares, either with or without
          par value, of the same class or another class or classes;

     (g)  Create a new class of shares having rights and preferences prior and
          superior to the shares of such class, or increase the rights and
          preferences or the number of authorized shares, of any class having
          rights and preferences prior or superior to the shares of such class;

     (h)  In the case of a preferred or special class of shares, divide the
          shares of such class into series and fix and determine the designation
          of such series and the variations in the relative rights and
          preferences between the shares of such series, or authorize the board
          of directors to do so;

     (i)  Limit or deny any existing preemptive rights of the shares of such
          class; or


                                              AMENDED AND RESTATED BYLAWS - P. 3
<PAGE>   4







     (j)  Cancel or otherwise affect dividends on the shares of such class which
          have accrued but have not been declared.

     1.11 VOTING OF SHARES BY CERTAIN HOLDERS. Shares standing in the name of
another corporation may be voted by such officer, agent or proxy as the bylaws
of such corporation may prescribe. In the absence of such provision, or in the
event more than one officer, agent or proxy has apparent authority to vote the
shares and they attempt to vote them inconsistently, the shares will not be
counted except upon a resolution by the Board of Directors of such other
corporation.

     Shares held by an administrator, executor, guardian or conservator may be
voted by him, either in person or by proxy, without a transfer of such shares in
his name. Shares standing in the name of a trustee may be voted by him, either
in person or by proxy, but no trustee shall be entitled to vote shares held by
him without a transfer of such shares into his name.

     Shares standing in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without the transfer thereof into his name if authority to do so is
contained in an appropriate order of the court by which such receiver was
appointed.

     A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

     Neither treasury shares of its own stock held by the corporation, nor
shares held by another corporation if a majority of the shares entitled to vote
for the election of directors of such other corporation are held by the
corporation, shall be voted at any meeting or counted in determining the total
number of outstanding shares at any given time for purposes of any meeting.


                                   SECTION II


                               BOARD OF DIRECTORS

     2.1  NUMBER AND QUALIFICATION. The business affairs and property of the
Corporation shall be managed under the direction of a Board of Directors, the
number of members of which shall be not less than one nor more than seven. The
Board of Directors may increase or decrease this number by resolution. A
decrease in the number of directors shall not shorten the term of an incumbent
director.

     2.2  ELECTION; TERM OF OFFICE. The directors shall be elected by the
shareholders at each annual shareholders' meeting or at a special meeting called
for that purpose. Despite the expiration of a director's term, the director
continues to serve until his or her successor is elected and qualified or until
there is a decrease in the authorized number of directors.

<PAGE>   5

     2.3  VACANCIES. Except as otherwise provided by law, vacancies in the Board
of Directors, whether caused by resignation, death, retirement,
disqualification, removal, increase in the number of directors, or otherwise,
may be filled by the Board of Directors, by the shareholders, or, if the
directors in office constitute less than a quorum of the Board of Directors, by
an affirmative vote of a majority of the remaining directors. A director elected
to fill a vacancy shall be elected for the unexpired term of his predecessor,
except that the term of a director elected due to an increase in the number of
directors expires at the next shareholders' meeting at which directors are
elected. A vacancy that will occur at a specific later date may be filled before
the vacancy occurs, but the new director may not take office until the vacancy
occurs.

     2.4  QUORUM AND VOTING. At any meeting of the Board of Directors, the
presence in person (including presence by electronic means such as a telephone
conference call) of a majority of the number of directors provided for in these
bylaws (or absent such a provision, then the number stated in the articles of
incorporation) shall constitute a quorum for the transaction of business. If a
quorum is present at the time of a vote, the affirmative vote of a majority of
the directors present at the time of the vote shall be the act of the Board of
Directors and of the Corporation except as may be otherwise specifically
provided by the Articles of Incorporation, by these Bylaws, or by law.

     A director who is present at a meeting of the Board of Directors when
action is taken is deemed to have assented to the action taken unless: (a) the
director objects at the beginning of the meeting, or promptly upon his or her
arrival, to holding it or to transacting business at the meeting; (b) the
director's dissent or abstention from the action taken is entered in the minutes
of the meeting; or (c) the director delivers written notice of his or her
dissent or abstention to the secretary of the meeting before its adjournment or
by registered mail to the Corporation within three days after adjournment of the
meeting. The right of dissent or abstention is not available to a director who
votes in favor of the action taken.

     2.5  REGULAR MEETINGS. Regular meetings of the Board of Directors shall be
held at such place, date and time as shall from time to time be fixed by
resolution of the Board.

     2.6  SPECIAL MEETINGS. Special meetings of the Board of Directors may be
held at any place and at any time and may be called by the Chairman of the

     2.7  NOTICE OF MEETINGS. Unless the Articles of Incorporation provide
otherwise, any regular meeting of the Board of Directors may be held without
notice of the date, time, place, or purpose of the meeting. Any special meeting
of the Board of Directors must be preceded by at least two days' notice of the
date, time, and place of the meeting, but not of its purpose, unless the
Articles of Incorporation or these Bylaws require otherwise. Notice may be given
personally, by facsimile, by mail, or in any other manner allowed by law. Oral
notice shall be sufficient only if a written record of such notice is included
in the Corporation's minute book.

     Notice shall be deemed effective at the earliest of: (a) receipt; (b)
delivery to the proper address or telephone number of the director as shown in
the Corporation's records; or (c) five days after its deposit in the United
States mail, as evidenced by the postmark, if correctly addressed and mailed
with first-class postage prepaid.

     Notice of any meeting of the Board of Directors may be waived by any
director at any time, by a signed writing, delivered to the Corporation for
inclusion in the minutes, either before or after the meeting. Attendance or
participation by a director at a meeting shall constitute a waiver of any
required notice of the meeting unless the director promptly objects to holding
the meeting or to the transaction of any business on the grounds that the
meeting was not lawfully convened and the director does not thereafter vote for
or assent to action taken at the meeting.

     2.8  DIRECTORS' ACTION WITHOUT A MEETING. The Board of Directors or a
committee thereof may take any action without a meeting that it could properly
take at a meeting if a written consent setting forth the action is signed by all
of the directors, or all of the members of the committee, as the case may be,
either before or after the action is taken, and if the consent is delivered to
the Corporation for inclusion in the minutes or filing with the corporate
records. Such action shall be effective upon the signing of a consent by the
last director to sign, unless the consent specifies a later effective date.

     2.9  COMMITTEES OF THE BOARD OF DIRECTORS. The Board of Directors, by
resolutions adopted by a majority of the members of the Board of Directors, may
create from among its members one or more committees and shall appoint the
members thereof. Each such committee must have two or more members, who shall be
directors and who shall serve at the pleasure of the Board of Directors. Each
committee of the Board of Directors may exercise the authority of the Board of
Directors to the extent provided in its enabling resolution and any pertinent
subsequent resolutions adopted in like manner, provided that the authority of
each such committee shall be subject to applicable law. Each committee of the
Board of Directors shall keep regular minutes of its proceedings and shall
report to the Board of Directors when requested to do so.

     2.10 TELEPHONE MEETINGS. Members of the Board of Directors or of any
committee appointed by the Board of Directors may participate in a meeting of
the Board of Directors or committee by means of a conference telephone or
similar communications equipment that enables all persons participating in the
meeting to hear each other at the same time during the meeting. Participation by
such means shall constitute presence in person at a meeting.

     2.11 COMPENSATION OF DIRECTORS. The Board of Directors may fix the
compensation of directors as such and may authorize the reimbursement of their
expenses.

     2.12 DIRECTOR CONFLICTS OF INTEREST. No contract or other transaction
between the corporation and one or more of its directors or any other
corporation, firm, association or entity in which one or more of its directors
are directors or officers or are financially interested, shall be either void or
voidable because of such relationship or interest or because such director or
directors are present at the meeting of the Board of Directors or a committee
thereof which

authorizes, approves or ratifies such contract or transaction or because his or
their votes are counted for such purposes, if:

     (a)  The fact of such relationship or interest is disclosed or known to the
          Board of Directors or committee which authorizes, approves or ratifies
          the contract or transaction by a vote or consent sufficient for the
          purpose without counting the votes or consents of such interested
          directors; or

     (b)  The fact of such relationship or interest is disclosed or known to the
          stockholders entitled to vote and they authorize, approve or ratify
          such contract or transaction by vote or written consent, in which vote
          or consent such interested directors may participate to the extent
          that they are also shareholders; or

     (c)  The contract or transaction is fair and reasonable to the corporation
          and the fact of such relationship or interest is fully and fairly
          disclosed or known to the corporation.

     Common or interested directors may be counted in determining the presence
of a quorum at a meeting of the Board of Directors or a committee thereof which
authorizes, approves or ratifies such contract or transaction.

shareholder gives the Corporation written notice of the demand at least five
business days before the date on which the shareholder wishes to make such

proper purpose, a shareholder may inspect and copy, during regular business
hours at a reasonable location specified by the Corporation, excerpts from
minutes of any meeting of the Board of Directors, records of any action of a
committee of the Board of Directors, records of actions taken by the Board of
Directors without a meeting, minutes of shareholders' meetings held or records
of action taken by shareholders without a meeting not within the past three

of the Corporation that may be otherwise granted to the shareholders by law.

                       MISCELLANEOUS PROCEDURAL PROVISIONS

     The Board of Directors may adopt rules of procedure to govern any meetings

of Directors, the chairman of the meeting shall make all decisions regarding the
procedures for any meeting.

                               AMENDMENT OF BYLAWS

     The Board of Directors is expressly authorized to make, alter and repeal
the Bylaws of the Corporation, subject to the power of the shareholders of the
Corporation to change or repeal the Bylaws.


                                    SECTION X

                     INDEMNIFICATION OF DIRECTORS AND OTHERS

     10.1 GRANT OF INDEMNIFICATION. Subject to Section 10.2, each person who was
or is made a party or is threatened to be made a party to or is involved
(including, without limitation, as a witness) in any threatened, pending, or
completed action, suit or proceeding, whether formal or informal, civil,
criminal, administrative or investigative (hereinafter a "proceeding"), by
reason of the fact that he or she is or was a director of the Corporation or
who, while a director of the Corporation, is or was serving at the request of
the Corporation as a director, officer, employee or agent of this or another
Corporation or of a partnership, joint venture, trust, other enterprise, or
employee benefit plan, whether the basis of such proceeding is alleged action in
an official capacity as a director or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent permitted by



                                             AMENDED AND RESTATED BYLAWS - P. 12
<PAGE>   12



applicable law, as then in effect, against all expense, liability and loss
(including attorneys' fees, costs, judgments, fines, ERISA excise taxes or
penalties and amounts to be paid in settlement) reasonably incurred or suffered
by such person in connection therewith, and such indemnification shall continue
as to a person who has ceased to be a director and shall inure to the benefit of
his or her heirs, executors and administrators.


     10.2 LIMITATIONS ON INDEMNIFICATION. Notwithstanding Section 10.1, no
indemnification shall be provided hereunder to any such person to the extent
that such indemnification would be prohibited by the Oregon Business Corporation
Act or other applicable law as then in effect. Except as provided in Section
10.4 with respect to proceedings seeking to enforce rights to indemnification,
the Corporation shall not indemnify any such person seeking indemnification in
connection with a proceeding (or part thereof) initiated by such person, except
where such proceeding (or part thereof) was authorized by the Board of Directors
of the Corporation.

     10.3 ADVANCEMENT OF EXPENSES. The right to indemnification conferred in
this section shall include the right to be paid by the Corporation the expenses
incurred in defending any such proceeding in advance of its final disposition,
except where the Board of Directors shall have adopted a resolution expressly
disapproving such advancement of expenses.

     10.4 RIGHT TO ENFORCE INDEMNIFICATION. If a claim under Section 10.1 is
not paid in full by the Corporation within forty (40) days after a written
claim has been received by the Corporation, or if a claim for expenses incurred
in defending a proceeding in advance of its final disposition authorized under
Section 10.3 is not paid within twenty (20) days after a written claim has been
received by the Corporation, the claimant may at any time thereafter bring suit
against the Corporation to recover the unpaid amount of the claim. To the extent
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim.

     The claimant shall be presumed to be entitled to indemnification hereunder
upon submission of a written claim (and, in an action brought to enforce a claim
for expenses incurred in defending any proceeding in advance of its final
disposition, where the required undertaking has been tendered to the
Corporation), and thereafter the Corporation shall have the burden of proof to
overcome the presumption that the claimant is so entitled.

     It shall be a defense to any such action (other than an action with respect
to expenses authorized under Section 10.3) that the claimant has not met the
standards of conduct which make it permissible hereunder or under the Oregon
Business Corporation Act for the Corporation to indemnify the claimant for the
amount claimed, but the burden of proving such defense shall be on the
Corporation.

     The failure of the Corporation (including its Board of Directors,
independent legal counsel, or its shareholders) to have made a determination
prior to the commencement of such action that indemnification of or
reimbursement or advancement of expenses to the claimant is proper in the
circumstances because he or she has met the applicable standard of conduct set
forth herein or in the Oregon Business Corporation Act shall not be a defense to
the action or create a presumption that the claimant is not so entitled.
Further, except as provided in Section 10.3, an actual



                                             AMENDED AND RESTATED BYLAWS - P. 13

<PAGE>   13
determination by the Corporation (including its Board of Directors, independent
legal counsel, or its shareholders) that the claimant is not entitled to
indemnification or to the reimbursement or advancement of expenses also shall
not be a defense to the action or create a presumption that the claimant is not
so entitled.

     10.5 NONEXCLUSIVITY. The right to indemnification and the payment of
expenses incurred in defending a proceeding in advance of its final disposition
conferred in this section shall be valid to the extent consistent with Oregon
law.

     10.6 INDEMNIFICATION OF OFFICERS, EMPLOYEES AND AGENTS. The Corporation
may, by action of its Board of Directors from time to time, provide
indemnification and pay expenses in advance of the final disposition of a
proceeding to officers, employees and agents of the Corporation on the same
terms and with the same scope and effect as the provisions of this section with
respect to the indemnification and advancement of expenses of directors and
officers of the Corporation or pursuant to rights granted pursuant to, or
provided by, the Oregon Business Corporation Act or on such other terms as the
Board may deem proper.

     10.7 INSURANCE AND OTHER SECURITY. The Corporation may maintain insurance,
at its expense, to protect itself and any individual who is or was a director,
officer, employee or agent of the Corporation or another Corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against or incurred by the individual in that capacity or arising from
his or her status as an officer, director, agent, or employee, whether or not
the Corporation would have the power to indemnify such person against the same
liability under the Oregon Business Corporation Act.

     The Corporation may enter into contracts with any director or officer of
the Corporation in furtherance of the provisions of this section and may create
a trust fund, grant a security interest or use other means (including, without
limitation, a letter of credit) to ensure the payment of such amounts as may be
necessary to effect indemnification as provided in this section.

     10.8 AMENDMENT OR MODIFICATION. This section may be altered or amended at
any time as provided in these Bylaws, but no such amendment shall have the
effect of diminishing the rights of any person who is or was an officer or
director as to any acts or omissions taken or omitted to be taken prior to the
effective date of such amendment.

     10.9 EFFECT OF SECTION. The rights conferred by this section shall be
deemed to be contract rights between the Corporation and each person who is or
was a director or officer. The Corporation expressly intends each such person to
rely on the rights conferred hereby in performing his or her respective duties
on behalf of the Corporation.

may require.


                                   ARTICLE II

                              Stockholder Meetings


     Section 1. Annual Meeting. The annual meeting of the Stockholders for the
election of Directors and the transaction of such other business as may properly
come before it will be held during the last week in September of each year.

     Section 2. Special Meetings. Special meetings of the Stockholders, other
than those regulated by statute, may be called at any time by the Board of
Directors, the President or the Stockholders holding, in the aggregate, not less
than ten percent (10%) of all outstanding shares entitled to vote at such
special meetings. The purpose(s) of the proposed meeting shall be stated in the
Notice of Meeting. No business other than that specified in the Notice of
Meeting shall be transacted at any such special meeting.

     Section 3. Place of Meeting. The annual and special meetings of
Stockholders will be held at the principal office of the Corporation in the
Commonwealth of Virginia or at such place within or without the Commonwealth of
Virginia as determined by the Board of Directors and set forth in the Notice of
Meeting.

     Section 4. Notice of Meeting. Written notice stating the place, day and
hour of the meeting and, in the case of a special meeting, the purpose or
purposes for which it is called shall be given not less than ten (10) nor more
than fifty (50) days before the date of the meeting, either personally or by
first-class mail, by or at the direction of the President or the Secretary or
the officers or persons calling the meeting, to each Stockholder of record
entitled to vote at such meeting. Notice of a Stockholders'


<PAGE>   2

                                      -2-



meeting to act on an amendment to the Articles of Incorporation or on a
reduction of stated capital or a plan of merger, consolidation or exchange shall
be given not less than twenty-five (25) nor more than fifty (50) days before
the date of the meeting (with such notice being accompanied by a copy of the
proposed amendment or plan of reduction, merger, consolidation or exchange). If
mailed, such notice shall be deemed to be given when deposited in the United
States mail, with postage thereon prepaid, addressed to the Stockholder at the
Stockholder's address as it appears on the stock transfer books of the
Corporation, unless the Stockholder has filed with the Secretary a written
request that notice intended for him be mailed to a different address, in which
case it shall be mailed to the address designated in such request.

     Section 5. Waiver of Notice of Meeting. Notice of any Stockholders' meeting
may be waived by any Stockholder by signing a waiver of such notice, whether
signed before or after the time set for the meeting. Notice of such meeting
shall not be required as to any Stockholder who shall attend such meeting in
person or by proxy, except where the Stockholder attends a meeting for the
express purpose of objecting to the transaction of any business because the
meeting is not lawfully called or convened.

     Section 6. Quorum. Except as otherwise provided in the Articles of
Incorporation, the presence, by person or by proxy, of the holders of a majority
of outstanding shares entitled to vote thereat shall be necessary to constitute
a quorum for the transaction of business at all meetings of Stockholders. If,
however, such quorum shall not be present or represented at any meeting of the
Stockholders, a majority of the shares so represented shall have the power to
adjourn that meeting to a future date at which a quorum shall be present or
represented. At such reconvened meeting, any business may be transacted which
might have been transacted at the meeting originally called.

     Section 7. Closing of Transfer Books and Fixing of Record Date. For the
purpose of determining Stockholders entitled to notice of or to vote at any
meeting of the Stockholders or any adjournment thereof, or entitled to receive
payment of any dividend, or in order to make a determination of Stockholders for
any other proper purpose, the Board of Directors may provide that the stock
transfer books shall be closed for a stated period, but not to exceed, in any
case, fifty (50) days. In lieu of closing the stock transfer books the Board of
Directors may fix in advance a date as the record date for any such
determination of Stockholders, such date in any case not more than fifty (50)
days prior to the date on which the particular action, requiring such
determination of Stockholders, is to be taken. If the stock transfer books are
not closed and no record date is fixed for the determination of Stockholders
entitled to notice of or to vote at a meeting of Stockholders, or Stockholders
entitled to receive payment of a dividend or for such other purpose, the date on
which notice of meeting is mailed or the date on which the resolution of the


<PAGE>   3
                                      -3-



Board of Directors declaring such dividend or allotment of rights is adopted, as
the case may be, shall be the record date for such determination of
Stockholders. When a determination of Stockholders entitled to vote at any
meeting of Stockholders has been made as provided in this section, such
determination shall apply to any adjournment thereof.

     Section 8. Voting Lists. At least ten (10) days prior to each meeting of
Stockholders, the officer or agent having charge of the stock transfer books for
shares of the Corporation shall make a complete list of the Stockholders
entitled to vote at such meeting, or any adjournment thereof, with the address
and the number and class of shares held by each, which list shall be subject to
inspection by any Stockholder during normal business hours for at least ten (10)
days prior to the meeting. The list also shall be produced at the meeting and
shall be subject to inspection by any Stockholder at any time during the
meeting. The original stock transfer book shall be prima facie evidence as to
who are the Stockholders entitled to examine such list or the transfer books or
to vote at any meeting of the Stockholders.

     Section 9. Voting. A Stockholder entitled to vote at a meeting may vote at
such meeting in person or by proxy. Except as otherwise provided by law or the
Articles of Incorporation, every Stockholder of record shall be entitled to one
(1) vote for each share of stock standing in his name on the books of the
Corporation on the record date fixed as herein provided. Moreover, except to the
extent that a greater number is required by law or the Articles of
Incorporation, all Stockholder action shall be determined by a vote of the
majority of the votes cast at a meeting of Stockholders by the holders of
shares entitled to vote thereon.

     Section 10. Proxies. Every proxy must be dated and signed by the
Stockholder or by his attorney-in-fact. No proxy shall be valid after the
expiration of eleven (11) months after the date of its execution, unless
otherwise provided in the proxy. Every proxy shall be revocable at the pleasure
of the Stockholder executing it, except when an irrevocable proxy is permitted
by Statute. All proxies shall be filed with the Secretary of the Corporation
before or at the time of the meeting. In the event that a proxy shall designate
two (2) or more persons to act as proxies, a majority of such persons present at
the meeting, or, if only one (1) is present, that one (1), shall have all of the
powers conferred by the proxy upon all persons so designated, unless the
instrument provides otherwise. If the proxy holders present at the meeting are
equally divided as to the manner of voting in a particular case, the voting of
such shares shall be prorated.

     Section 11. Action by Stockholders Without a Meeting. Whenever by a
provision of Statute, the Articles of Incorporation or by these Bylaws the vote
of Stockholders is required or permitted to be taken at a meeting thereof in
connection with any corporate action, the meeting and the vote of the
Stockholders may be



<PAGE>   4



                                       -4-




dispensed with if all the Stockholders who would have been entitled to vote upon
the action if such meeting were held shall consent in writing to such corporate
action being taken.



                                   ARTICLE III

                                    Directors


     Section 1. Number and Qualifications. The entire Board of Directors shall
consist of three (3) members. However, in no event shall these Bylaws be amended
to fix the number at less than one (1) Director. No minor shall serve as a
Director. Unless the Articles of Incorporation provide otherwise, Directors need
not be residents of the Commonwealth or Stockholders of the Corporation.

     Section 2. Manner of Election. The Directors shall be elected at the annual
meeting of the Stockholders, except as herein provided for filling vacancies.

     Section 3. Term of Office. The term of office of each Director shall be
until the next annual meeting of the Stockholders and until his successor has
been duly elected and has been qualified, unless he sooner dies, resigns or is
removed.

     Section 4. Duties, Powers and Manner of Acting. The Board of Directors
shall have full control and management of the affairs, business and property of
the Corporation. The Directors shall in all cases act as a Board, regularly
convened, and in the transaction of business the act of a majority of the
Directors present at a meeting, except to the extent a greater number is
required by law or the Articles of Incorporation, shall be the act or the Board,
provided a quorum is present. The Directors may adopt such rules and regulations
for the conduct of their meetings and for the management of the Corporation
which they may deem proper not inconsistent with law or these Bylaws.

     Section 5. Presumption of Assent. A Director who is present at a meeting of
the Board of Directors at which action on any corporate matter is taken shall be
presumed to have assented to the action taken unless (a) he announces his
dissent at the meeting and (b) either his dissent shall be entered in the
minutes of the meeting or he shall file his written dissent to such action with
the person acting as the Secretary of the meeting before the adjournment thereof
or shall forward such written dissent, immediately after the meeting is
adjourned, to the Secretary of the meeting or the Corporation by registered mail
or personally. Such right to dissent shall not apply to a Director who voted in
favor of such action.

     Section 6. Annual Meetings. After each annual meeting of Stockholders, the
Board of Directors shall hold its annual meeting at the same place as and
immediately following such annual meeting of Stockholders for the purpose of the
election or appointment of officers and the transaction of such other business
as may come before the meeting. The place and time of such meeting may be varied
by written consent of all the Directors.

     Section 7. Regular Meetings. Regular meetings of the Board of Directors may
be held without notice at such time and at such place as shall be determined in
advance from time to time by the Board of Directors.

     Section 8. Special Meetings. Special meetings of the Board of Directors
may be called by the President at any time. He must, upon the written request of
a majority of all Directors, call a special meeting to be held not more than ten
(10) days after he has received such request.

     Section 9. Notice of Meetings. No notice need be given of any annual or
regular meeting of the Board. Notice of special meetings shall be served upon
each Director in person, by telegram or by mail addressed to him at his last
known post office address, at least two (2) days prior to the date of such
meeting, specifying the place, day and hour of the meeting. If notice is mailed
or sent by telegram, such notice shall be deemed to be delivered when deposited
in the United States mail with postage thereon prepaid or when the telegram is
properly delivered to the telegraph company. Neither the business to
be transacted at, nor the purpose of, any annual, regular or special meeting of
the Board of Directors need be specified in the notice or waiver of such notice
of such meetings. At any meeting at which all of the Directors shall be present,
although held without notice, any business may be transacted which might have
been transacted if the meeting had been duly called.

     Section 10. Waiver of Notice of Meeting. Notice of any Board of Directors'
meeting may be waived by any Director by signing a waiver of such notice,
whether signed before or after the time set for the meeting. Notice of such
meeting shall not be required as to any Director who shall attend such meeting
in person or by proxy, except where the Director attends a meeting for the
express purpose of objecting to the transaction of any business because the
meeting is not lawfully called or convened.

     Section 11. Place of Meeting. The Board of Directors may hold its meetings
either within or without the Commonwealth of Virginia. Unless otherwise provided
herein, the person(s) calling such meetings may fix the place of such meetings.
If no such designation is made, the place of the meeting shall be the principal
office of the Corporation.

                                       -6-



         Section 12. Quorum. At any meeting of the Board of Directors the
presence of a majority of the number of Directors as determined from time to
time shall be necessary to constitute a quorum for the transaction of business,
unless a greater number is required by the Articles of Incorporation. However,
should a quorum not be present, a lesser number may adjourn the meeting until
some further time, not more than ten (10) days later when it is reasonably
possible to obtain a quorum.

     Section 13. Voting. At all meetings of the Board of Directors, each
Director shall have one (1) vote irrespective of the number of shares that he
may hold.

     Section 14. Compensation. Each Director shall be entitled to receive for
attendance at each meeting of the Board or of any duly constituted committee
thereof which he attends reimbursement of his expenses, and such fee as is fixed
by the Board or a stated salary as Director. No payment shall preclude any
Director from serving the Corporation in any other capacity and receiving
compensation therefore.

     Section 15. Vacancies. Except as may be provided in the Articles of
Incorporation, any vacancy occurring in the Board of Directors, including a
vacancy resulting from an increase, by not more than two (2), in the number of
Directors, may be filled by the affirmative vote of a majority of the remaining
Directors (though less than a quorum of the Board of Directors) at a regular or
special meeting which shall be called for that purpose within sixty (60) days
after the occurrence of the vacancy. The Director thus chosen shall hold office
for the unexpired term of his predecessor in office.

     Section 16. Removal of Directors. Any Director may be removed either with
or without cause (except as provided by law), at any time, by vote of the
Stockholders holding a majority of the issued and outstanding shares entitled to
vote at an election of the Director sought to be removed, at any special
Stockholders' meeting called for that purpose, or at the annual Stockholders'
meeting. Any such removal shall be without prejudice to the contract rights, if
any, of the person removed. No Director may be removed, in case cumulative
voting is provided in the Articles of Incorporation, if the vote of a sufficient
number of shares are cast against his removal which, if then cumulatively voted
at an election of a full Board, would be sufficient to elect him.

     Section 17. Resignation. Any Director may resign his office at any time.
Such resignation is to be made in writing, delivered to the President or
secretary and to take effect at the time specified in such notice.

     Section 18. Action by Directors Without A Meeting. Any action required or
permitted to be taken by any provisions of law, the Articles of Incorporation or
these Bylaws at any meeting of


<PAGE>   7






                                      -7-



the Board of Directors or of any committee thereof may be taken without a
meeting if a written consent, setting forth the action, is signed, either before
or after such action, by all members of the Board of Directors or of such
committee, as the case may be, and filed in the minutes of the proceedings of
the Board of Directors or such committee, as the case may be.

     Section 19. Meeting by Telephone. Unless otherwise provided by the Articles
of Incorporation, Directors or the members of any committee thereof will be
deemed present at a meeting of the Board of Directors or of any such committee,
as the case may be, if the meeting is conducted using a conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other at the same time. Participation by such means
shall constitute presence in person at a meeting.


                                   ARTICLE IV

                                    Officers


     Section 1. Officers and Qualifications. The officers of the Corporation
shall consist of a President, Secretary and Treasurer. Such Vice-Presidents and
other officers and assistant officers and agents as deemed necessary may be
elected or appointed by the Board of Directors or chosen in such other manner as
may be prescribed by the Bylaws. Any two (2) or more offices may be held by the
same person except the offices of President and Secretary (provided, however, if
the Corporation has only one (1) Stockholder, he may hold all offices), but in
no case (except if the Corporation has only one (1) Stockholder and one person
who holds all offices) shall one (1) person sign a single instrument of any kind
in more than one (1) capacity.

     Section 2. Election. All officers of the Corporation shall be elected
annually by the Board of Directors at its annual meeting. If the election of
officers shall not be held at such meeting, such election shall be held as soon
thereafter as is convenient.

     Section 3. Term of Office. All officers shall hold office for one (1) year
and until their successors have been duly elected and have qualified, unless
they sooner die, resign or are removed.

     Section 4. Vacancies. All vacancies in any office shall be filled promptly
by the Board of Directors either at annual or regular meetings or at a meeting
specially called for that purpose.

     Section 5. Removal of Officers or Agents. Any officer or agent may be
removed either with or without cause at any time by vote of the majority of the
Board of Directors whenever the Board of Directors in its absolute discretion
shall consider that the best interests of the Corporation would be served
thereby. Any officer or agent appointed otherwise than by the Board of




<PAGE>   8


                                       -8-




Directors may be removed with or without cause at any time by any officer or
person(s) having authority to appoint, except as may otherwise be provided in
the Bylaws, whenever such officer in his absolute discretion shall consider that
the best interests of the Corporation will be served thereby. Any such removal
shall be without prejudice to the contract rights, if any, of the person
removed. Election or appointment of an officer or agent shall not of itself
create contract rights.

     Section 6. Compensation of Officers. The officers shall receive such salary
or compensation as may be fixed by the Board of Directors. If any salary
payment, commission, employee fringe benefit, expense allowance or payment or
other expense incurred by the Corporation for the benefit of an officer,
Director, agent or employee of the Corporation is disallowed in whole or in
part as a deductible expense of the Corporation for federal income tax
purposes, the officer, Director, agent or employee shall promptly reimburse the
Corporation, upon notice and demand, to the full extent of the disallowance.

     Section 7. Duties of Officers. The duties and powers of the officers of the
Corporation shall be as follows and shall hereafter be set by resolution of the
Board of Directors:

the approval of the Board of Directors.

     e.   He may sign and execute all contracts in the name of the Corporation
and all checks, notes, drafts or other orders for the payment of money. This

     g.   He shall cause all books, reports, statements and certificates to be

     d.   He shall keep at the principal office of the Corporation a book of
records containing the names, alphabetically arranged, of all persons who are
Stockholders of the Corporation, showing their places of residence, the number
and class of shares held by them respectively and the dates when they
respectively became the owners of record thereof. He shall keep such books of
record and minutes of the proceedings of the Stockholders open daily during the
usual business hours for inspection, within the limits prescribed by law, by any
person duly authorized to inspect such record. At the request of the person
entitled to inspection thereof, he shall prepare and make available a current
list of the officers and Directors of the Corporation and their resident

Corporation and any one or more of its Directors or officers or any other
corporation, firm, association or entity in which one or more of its Directors
or officers are Directors or officers or are financially interested shall be
either void or voidable because of such relationship or interest, because such
Director or Directors were present or were counted in determining the presence
of a quorum at the meeting of the Board of Directors or of a committee thereof
which authorizes, approves or ratifies such contract or transaction or because
such Director's or Directors' votes are counted for such purpose if: (a) the

Directors or committee which authorizes, approves or ratifies the contract or
transaction by a vote sufficient for the purpose without counting the votes of
such interested Directors; (b) the fact of such relationship or interest is

     Section 1. Eligible Stockholders. The shares of the Corporation shall be

present intention of making any disposition or sale thereof.

     Section 5. Transfer of Shares. Transfer of shares of the Corporation shall
be made upon its books by the holder of the shares in person or by the holder's
lawfully constituted representative, upon surrender of the certificate of stock
for cancellation. The person in whose name shares stand on the books of the
Corporation shall be deemed by the Corporation to be the owner thereof for all
purposes, and the Corporation shall not be bound to recognize any equitable or
other claim to or interest in such share on the part of any other person,
whether or not it shall have express or other notice thereof, save as expressly

alleged to have been lost, stolen or destroyed, upon the making of an affidavit
of that fact by the person claiming the certificate of stock to be lost, stolen
or destroyed. Such replacement certificates shall be marked "Replacement" on the
face thereof. When authorizing such issue of a new replacement certificate or
certificates, the Board of Directors may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed certificate or certificates, or the owner's legal representatives to
produce satisfactory evidence of such loss, theft or destruction and/or give the
Corporation a bond and/or an undertaking in such sum, and upon such terms, as it
may direct as indemnity against any claim that may be made against the
Corporation with respect to the certificate alleged to have been lost, stolen or
destroyed.

Corporation, whenever in its exercise or its discretion it may deem such
declaration advisable. Such dividends may be paid in cash or property (including

                                  LISN COMPANY


     The undersigned, desiring to form a corporation for profit under the
General Corporation law of Ohio, does hereby certify:

     FIRST:    The name of the Corporation is:

                                  LISN COMPANY

     SECOND:   The place in Ohio where the principal office of the Corporation
shall be located is Cleveland, Cuyahoga County.

     THIRD:    The purposes for which, and for any of which, the Corporation is
formed are as follows:

     1)   To install, improve and dismantle central office telephone
          equipment.  To engage primarily in the sale of telephone cables and
          switching equipment to public utility companies; and

     2)   In general, to carry on any lawful business whatsoever in connection
          with the business of the Corporation or which is calculated, directly
          or indirectly, to promote the interests of the Corporation or to
          enhance the value of its properties; and to have and exercise all
          rights, powers and privileges which are now or may hereafter be
          conferred upon corporations by the laws of Ohio.

     The Corporation reserves the right at any time and from time to time to
change substantially its purposes pursuant to the affirmative vote or approval
of the holders of shares entitled to exercise the proportion of the voting power
of the Corporation now or hereafter required by statute for such approval, and
such vote or approval shall be binding and conclusive upon every shareholder of
the Corporation as fully as if such shareholder had voted therefor; and no
shareholder, notwithstanding that he may have voted against such change of
purpose or may have objected in writing thereto, shall be entitled to payment of
the fair cash value of his shares.

     FOURTH:    The number of shares of Capital Stock which the Corporation is
authorized to have outstanding is SEVEN HUNDRED FIFTY (750) shares of Common
Stock, without par value.

     FIFTH:     Notwithstanding any provision of the Ohio Revised Code now or
hereafter in force otherwise requiring for any purpose the vote, consent,
waiver or release of the holders of shares entitling them to exercise
two-thirds, or any other portion, of the voting power of the Corporation or of
any class or classes of shares thereof,
<PAGE>   2

such action, unless otherwise expressly required by statute or by
these Articles of Incorporation, may be taken by the vote, consent,
waiver or release of the holders of shares entitling them to exercise
a majority of the voting power of the Corporation or of such class or
classes.

     SIXTH:    No holder of any class of shares of the Corporation shall
have any pre-emptive or preferential right to subscribe to or purchase any
shares of any class of stock of the Corporation, whether now or hereafter
authorized and whether unissued or in the treasury, or any obligations
convertible into shares of any class of stock of the Corporation, at any time
issued or sold, or any right to subscribe to or purchase any thereof.

     SEVENTH:  The Corporation may, from time to time, pursuant to authorization
by its Directors and without action by the shareholders, purchase or otherwise
acquire shares of the Corporation of any class or classes in such manner, upon
such terms and in such amounts as the Directors shall determine, to the extent
permitted by law; subject, however, to such limitation or restriction, if any,
as may be imposed by the terms or provisions of any class of shares or other
securities of the Corporation outstanding at the time of the purchase or
acquisition in question.

     EIGHTH:   A Director or officer of the Corporation shall not be
disqualified by his office from dealing or contracting with the Corporation as a
vendor, purchaser, employee, agent or otherwise, nor shall any transaction,
contract or other act of the Corporation be void or voidable or in any way
affected or invalidated by reason of the fact that any Director or officer, or
any firm in which such Director or officer is a member, or any corporation of
which such Director or officer is a shareholder, director or officer, is in any
way interested in such transaction, contract or other act, provided the fact
that such Director, officer, firm or corporation is so interested shall be
disclosed or shall be known to the Board of Directors at the time at which any
action upon any such transaction, contract or other act occurred; and any such
Director may be counted in determining the existence of a quorum at any meeting
of the Board of Directors of the Corporation which shall authorize or take
action in respect of any such transaction, contract or other act, and may vote
thereat to authorize, ratify or approve any such transaction, contract or other
act with like force and effect as if he or any firm of which he is a member or
any corporation of which he is a shareholder, director or officer were not
interested in such transaction, contract or other act.

     NINTH:    Any and every statute of the State of Ohio hereafter enacted,
whereby the rights, powers or privileges of corporations or of the shareholders
of corporations organized under the laws of the State of Ohio are increased or
diminished or in any way affected, or whereby effect is given to the action
taken by any number, less than all, of the shareholders of any such corporation,
shall apply to the Corporation and shall be binding not only upon the
Corporation but


                                      -2-
<PAGE>   3

upon every shareholder of the Corporation to the same extent as if such statute
had been in force at the time of the filing of those Articles of Incorporation
in the office of the Secretary of State of Ohio.

          IN WITNESS WHEREOF, I have hereunto subscribed my name this 9th day of
January, 1987.

         Section 11. Action by Written Consent. Unless otherwise provided in the
certificate of incorporation, any action required to be taken at any annual or
special meeting of stockholders of the corporation, or any action which may be
taken at any annual or special meeting of such stockholders, may be taken

consents in writing, setting forth the action so taken and bearing the dates of
signature of the stockholders who signed the consent or consents, shall be

proceedings of meetings of the stockholders are recorded. Delivery made to the
corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested provided, however, that no consent or consents
delivered by certified or registered mail shall be deemed delivered until such
consent or consents are actually received at the registered office. All consents
properly delivered in accordance with this section shall be deemed to be
recorded when so delivered. No written consent shall be effective to take the
corporate action referred to therein unless, within sixty days of the earliest
dated consent delivered to the corporation as required by this section, written
consents signed by the holders of a sufficient number of shares to take such
corporate action are so recorded. Prompt notice of the taking of the corporate
action without a meeting by less than unanimous written consent shall be given
to those stockholders who have not consented in writing. Any action taken
pursuant to such written consent or consents of the stockholders shall have the
same force and effect as if taken by the stockholders at a meeting thereof.

         Section 2. Number, Election and Term of Office. The number of directors
which shall constitute the first board shall be one (1). Thereafter, the number
of directors shall be established from time to time by resolution of the board.
The directors shall be elected by a plurality of the votes of the shares present
in person or represented by proxy at the meeting and entitled to vote in the
election of directors. The directors shall be elected in this manner at the
annual meeting of the stockholders, except as provided in Section 4 of this
Article III. Each director elected shall hold office until a successor is duly
elected and qualified or until his or her earlier death, resignation or removal
as hereinafter provided.

         Section 3. Removal and Resignation. Any director or the entire board of
directors may be removed at any time, with or without cause, by the holders of a
majority of the shares then entitled to vote at an election of directors.
Whenever the holders of any class or series are entitled to elect one or more
directors by the provisions of the corporation's certificate of incorporation,
the provisions of this section shall apply, in respect to the removal
without cause of a director or directors so elected, to the vote of the holders
of the outstanding shares of that class or series and not to the vote of the
outstanding shares as a whole. Any director may resign at any time upon written
notice to the corporation.

         Section 4. Vacancies. Vacancies and newly created directorships
resulting from any increase in the authorized number of directors may be filled
by a majority of the directors then in office, though less than a quorum, or by
a sole remaining director. Each director so chosen shall hold office until a
successor is duly elected and qualified or until his or her earlier death,
resignation or removal as herein provided.

         Section 5. Annual Meetings. The annual meeting of each newly elected
board of directors shall be held without other notice than this by-law
immediately after, and at the same place as, the annual meeting of stockholders.

         Section 6. Other Meetings and Notice. Regular meetings, other than the
annual meeting, of the board of directors may be held without notice at such
time and at such place as shall from time to time be determined by resolution of
the board. Special meetings of the board of directors may be called by or at the
request of the president or any director on at least 24 hours notice to each
director, either personally, by telephone, by mail, or by telegraph.

         Section 7. Quorum, Required Vote and Adjournment. A majority of the
total number of directors shall constitute a quorum for the transaction of
business. The vote of a majority of directors present at a meeting at which a
quorum is present shall be the act of the board of directors. If a quorum shall
not be present at any meeting of the board of directors, the directors present
thereat may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.

         Section 8. Committees. The board of directors may, by resolution passed
by a majority of the whole board, designate one or more committees, each
committee to consist of one or more of the


                                     - 4 -
<PAGE>   5

directors of the corporation, which to the extent provided in such resolution or
these by-laws shall have and may exercise the powers of the board of directors
in the management and affairs of the corporation except as otherwise limited by
law. The board of directors may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee. Such committee or committees shall have such name
or names as may be determined from time to time by resolution adopted by the
board of directors. Each committee shall keep regular minutes of its meetings
and report the same to the board of directors when required.

         Section 9. Committee Rules. Each committee of the board of directors
may fix its own rules of procedure and shall hold its meetings as provided by
such rules, except as may otherwise be provided by a resolution of the board of
directors designating such committee. In the event that a member and that
member's alternate, if alternates are designated by the board of directors as
provided in Section 8 of this Article III, of such committee is or are absent or
disqualified, the member or members thereof present at any meeting and not
disqualified from voting, whether or not such member or members constitute a
quorum, may unanimously appoint another member of the board of directors to act
at the meeting in place of any such absent or disqualified member.

         Section 10. Communications Equipment. Members of the board of directors
or any committee thereof may participate in and act at any meeting of such board
or committee through the use of a conference telephone or other communications
equipment by means of which all persons participating in the meeting can hear
each other, and participation in the meeting pursuant to this section shall
constitute presence in person at the meeting.

         Section 11. Waiver of Notice and Presumption of Assent. Any member of
the board of directors or any committee thereof who is present at a meeting
shall be conclusively presumed to have waived notice of such meeting except when
such member attends for the express purpose of objecting at the beginning of the
meeting to the transaction of any business because the meeting is not lawfully
called or convened. Such member shall be conclusively presumed to have assented
to any action taken unless his or her dissent shall be entered in the minutes of
the meeting or unless his or her written dissent to such action shall be filed
with the person acting as the secretary of the meeting before the adjournment
thereof or shall be forwarded by registered mail to the secretary of the
corporation immediately after the adjournment of the meeting. Such right to
dissent shall not apply to any member who voted in favor of such action.

         Section 12. Action by Written Consent. Unless otherwise restricted by
the certificate of incorporation, any action required or permitted to be taken
at any meeting of the board of directors, or of any committee thereof, may be
taken without a meeting if all members of the board or committee, as the case
may be, consent thereto in writing, and the writing or writings are filed with
the minutes of proceedings of the board or committee.

                                    ARTICLE V

                INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS

         Section 1. Nature of Indemnity. Each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer,
of the corporation or is or was serving at the request of the corporation as a
director, officer, employee, fiduciary, or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, shall be indemnified and
held harmless by the corporation to the fullest extent which it is empowered to
do


                                     - 8 -
<PAGE>   9
so by the General Corporation Law of the State of Delaware, as the same
exists or may hereafter be amended against all expense, liability and loss
(including attorneys' fees actually and reasonably incurred by such person in
connection with such proceeding) and such indemnification shall inure to the
benefit of his or her heirs, executors and administrators; provided, however,
that, except as provided in Section 2 hereof, 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 in this
Article V shall be a contract right and, subject to Sections 2 and 5 hereof,
shall include the right to be paid by the corporation the expenses incurred in
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
foregoing indemnification of directors and officers.

         Section 2. Procedure for Indemnification of Directors and Officers. Any
indemnification of a director or officer of the corporation under Section 1 of
this Article V or advance of expenses under Section 5 of this Article V shall be
made promptly, and in any event within 30 days, upon the written request of the
director or officer. If a determination by the corporation that the director or
officer is entitled to indemnification pursuant to this Article V is required,
and the corporation fails to respond within sixty days to a written request for
indemnity, the corporation shall be deemed to have approved the request. If the
corporation denies a written request for indemnification or advancing of
expenses, in whole or in part, or if payment in full pursuant to such request is
not made within 30 days, the right to indemnification or advances as granted by
this Article V shall be enforceable by the director or officer in any court of
competent jurisdiction. Such person's costs and expenses incurred in connection
with successfully establishing his or her right to indemnification, in whole or
in part, in any such action shall also be indemnified by the corporation. It
shall be a defense to any such action (other than an action brought to enforce a
claim for expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking, if any, has been tendered to the
corporation) that the claimant has not met the standards of conduct which make
it permissible under the General Corporation Law of the State of Delaware for
the corporation to indemnify the claimant for the amount claimed, but the burden
of such defense shall be on the corporation. Neither the failure of the
corporation (including its board of directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
General Corporation Law of the State of Delaware, nor an actual determination by
the corporation (including its board of directors, independent legal counsel, or
its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

         Section 3. Article Not Exclusive. The rights to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Article V shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute,

provision of the certificate of incorporation, by-law, agreement, vote of
stockholders or disinterested directors or otherwise.

         Section 4. Insurance. The corporation may purchase and maintain
insurance on its own behalf and on behalf of any person who is or was a
director, officer, employee, fiduciary, or agent of the corporation or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him or her and incurred by him
or her in any such capacity, whether or not the corporation would have the power
to indemnify such person against such liability under this Article V.

         Section 5. Expenses. Expenses incurred by any person described in
Section 1 of this Article V in defending a proceeding shall be paid by the
corporation in advance of such proceeding's final disposition unless otherwise
determined by the board of directors in the specific case upon receipt of an
undertaking by or on behalf of the director or officer to repay such amount if
it shall ultimately be determined that he or she is not entitled to be
indemnified by the corporation. Such expenses incurred by other employees and
agents may be so paid upon such terms and conditions, if any, as the board of
directors deems appropriate.

         Section 6. Employees and Agents. Persons who are not covered by the
foregoing provisions of this Article V and who are or were employees or agents
of the corporation, or who are or were serving at the request of the corporation
as employees or agents of another corporation, partnership, joint venture, trust
or other enterprise, may be indemnified to the extent authorized at any time or
from time to time by the board of directors.

         Section 7. Contract Rights. The provisions of this Article V shall be
deemed to be a contract right between the corporation and each director or
officer who serves in any such capacity at any time while this Article V and the
relevant provisions of the General Corporation Law of the State of Delaware or
other applicable law are in effect, and any repeal or modification of this
Article V or any such law shall not affect any rights or obligations then
existing with respect to any state of facts or proceeding then existing.

         Section 8. Merger or Consolidation. For purposes of this Article V,
references to "the corporation" shall include, in addition to the resulting
corporation, any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under this Article V
with respect to the resulting or surviving corporation as he or she would have
with respect to such constituent corporation if its separate existence had
continued.

                                   ARTICLE VI

                             CERTIFICATES OF STOCK

         Section 1. Form. Every holder of stock in the corporation shall be
entitled to have a certificate, signed by, or in the name of the corporation by
the president or a vice-president and the secretary or an assistant secretary of
the corporation, certifying the number of shares owned by such holder in the
corporation. If such a certificate is countersigned (1) by a transfer agent or
an assistant transfer agent other than the corporation or its employee or (2) by
a registrar, other than the corporation or its employee, the signature of any
such president, vice-president, secretary, or assistant secretary may be
facsimiles. In case any officer or officers who have signed, or whose facsimile
signature or signatures have been used on, any such certificate or certificates
shall cease to be such officer or officers of the corporation whether because of
death, resignation or otherwise before such certificate or certificates have
been delivered by the corporation, such certificate or certificates may
nevertheless be issued and delivered as though the person or persons who signed
such certificate or certificates or whose facsimile signature or signatures have
been used thereon had not ceased to be such officer or officers of the
corporation. All certificates for shares shall be consecutively numbered or
otherwise identified. The name of the person to whom the shares represented
thereby are issued, with the number of shares and date of issue, shall be
entered on the books of the corporation. Shares of stock of the corporation
shall only be transferred on the books of the corporation by the holder of
record thereof or by such holder's attorney duly authorized in writing, upon
surrender to the corporation of the certificate or certificates for such shares
endorsed by the appropriate person or persons, with such evidence of the
authenticity of such endorsement, transfer, authorization, and other matters as
the corporation may reasonably require, and accompanied by all necessary stock
transfer stamps. In that event, it shall be the duty of the corporation to issue
a new certificate to the person entitled thereto, cancel the old certificate or
certificates, and record the transaction on its books. The board of directors
may appoint a bank or trust company organized under the laws of the United
States or any state thereof to act as its transfer agent or registrar, or both
in connection with the transfer of any class or series of securities of the
corporation.

         Section 2. Lost Certificates. The board of directors may direct a new
certificate or certificates to be issued in place of any certificate or
certificates previously issued by the corporation alleged to have been lost,
stolen, or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen, or destroyed. When
authorizing such issue of a new certificate or certificates, the board of
directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen, or destroyed certificate or
certificates, or his or her legal representative, to give the corporation a bond
sufficient to indemnify the corporation against any claim that may be made
against the corporation on account of the loss, theft or destruction of any such
certificate or the issuance of such new certificate.

         Section 3. Fixing a Record Date for Stockholder Meetings. In order that
the corporation may determine the stockholders entitled to notice of or to vote
at any meeting of stockholders or any adjournment thereof, the board of
directors may fix a record date, which record date shall not precede


                                     - 11 -
<PAGE>   12

the date upon which the resolution fixing the record date is adopted by the
board of directors, and which record date shall not be more than sixty nor less
than ten days before the date of such meeting. If no record date is fixed by the
board of directors, the record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be the close of business
on the next day preceding the day on which notice is given, or if notice is
waived, at the close of business on the day next preceding the day on which the
meeting is held. A determination of stockholders of record entitled to notice of
or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the board of directors may fix a new record
date for the adjourned meeting.

         Section 4. Fixing a Record Date for Action by Written Consent. In order
that the corporation may determine the stockholders entitled to consent to
corporate action in writing without a meeting, the board of directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the board of directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the board of directors. If no
record date has been fixed by the board of directors, the record date for
determining stockholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the board of directors is required by
statute, shall be the first date on which a signed written consent setting forth
the action taken or proposed to be taken is delivered to the corporation by
delivery to its registered office in the State of Delaware, its principal place
of business, or an officer or agent of the corporation having custody of the
book in which proceedings of meetings of stockholders are recorded. Delivery
made to the corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested. If no record date has been fixed by
the board of directors and prior action by the board of directors is required by
statute, the record date for determining stockholders entitled to consent to
corporate action in writing without a meeting shall be at the close of business
on the day on which the board of directors adopts the resolution taking such
prior action.

         Section 5. Fixing a Record Date for Other Purposes. In order that the
corporation may determine the stockholders entitled to receive payment of any
dividend or other distribution or allotment or any rights or the stockholders
entitled to exercise any rights in respect of any change, conversion or exchange
of stock, or for the purposes of any other lawful action, the board of directors
may fix a record date, which record date shall not precede the date upon which
the resolution fixing the record date is adopted, and which record date shall be
not more than sixty days prior to such action. If no record date is fixed, the
record date for determining stockholders for any such purpose shall be at the
close of business on the day on which the board of directors adopts the
resolution relating thereto.

         Section 6. Registered Stockholders. Prior to the surrender to the
corporation of the certificate or certificates for a share or shares of stock
with a request to record the transfer of such share or shares, the corporation
may treat the registered owner as the person entitled to receive dividends, to
vote, to receive notifications, and otherwise to exercise all the rights and
powers of an owner.

         Section 7. Subscriptions for Stock. Unless otherwise provided for in
the subscription agreement, subscriptions for shares shall be paid in full at
such time, or in such installments and at such times, as shall be determined by
the board of directors. Any call made by the board of directors for payment on
subscriptions shall be uniform as to all shares of the same class or as to all
shares of the same series. In case of default in the payment of any installment
or call when such payment is due, the corporation may proceed to collect the
amount due in the same manner as any debt due the corporation.

                                   ARTICLE VII

                               GENERAL PROVISIONS

         Section 1. Dividends. Dividends upon the capital stock of the
corporation, subject to the provisions of the certificate of incorporation, if
any, may be declared by the board of directors at any regular or special
meeting, pursuant to law. Dividends may be paid in cash, in property, or in
shares of the capital stock, subject to the provisions of the certificate of
incorporation. Before payment of any dividend, there may be set aside out of any
funds of the corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or any other purpose
and the directors may modify or abolish any such reserve in the manner in which
it was created.

         Section 2. Checks, Drafts or Orders. All checks, drafts, or other
orders for the payment of money by or to the corporation and all notes and other
evidences of indebtedness issued in the name of the corporation shall be signed
by such officer or officers, agent or agents of the corporation, and in such
manner, as shall be determined by resolution of the board of directors or a duly
authorized committee thereof.

         Section 3. Contracts. The board of directors may authorize any officer
or officers, or any agent or agents, of the corporation to enter into any
contract or to execute and deliver any instrument in the name of and on behalf
of the corporation, and such authority may be general or confined to specific
instances.

         Section 4. Loans. No loans shall be made by the corporation to its
officers or directors, and no loans shall be made by the corporation secured by
its shares. No loans shall be made or contracted on behalf of the corporation
and no evidences of indebtedness shall be issued in its name unless authorized
by resolution of the board of directors. Such authority may be general or
confined to specific instances.

         Section 5. Fiscal Year. The fiscal year of the corporation shall be
fixed by resolution of the board of directors.

<PAGE>   14

         Section 6. Corporate Seal. The board of directors shall provide a
corporate seal which shall be in the form of a circle and shall have inscribed
thereon the name of the corporation and the words "Corporate Seal, Delaware".
The seal may be used by causing it or a facsimile thereof to be impressed or
affixed or reproduced or otherwise.

         Section 7. Voting Securities Owned By Corporation. Voting securities in
any other corporation held by the corporation shall be voted by the president,
unless the board of directors specifically confers authority to vote with
respect thereto, which authority may be general or confined to specific
instances, upon some other person or officer. Any person authorized to vote
securities shall have the power to appoint proxies, with general power of
substitution.

         Section 8. Inspection of Books and Records. Any stockholder of record,
in person or by attorney or other agent, shall, upon written demand under oath
stating the purpose thereof, have the right during the usual hours for business
to inspect for any proper purpose the corporation's stock ledger, a list of its
stockholders, and its other books and records, and to make copies or extracts
therefrom. A proper purpose shall mean any purpose reasonably related to such
person's interest as a stockholder. In every instance where an attorney or other
agent shall be the person who seeks the right to inspection, the demand under
oath shall be accompanied by a power of attorney or such other writing which
authorizes the attorney or other agent to so act on behalf of the stockholder.
The demand under oath shall be directed to the corporation at its registered
office in the State of Delaware or at its principal place of business.

         Section 9. Section Headings. Section headings in these by-laws are for
convenience of reference only and shall not be given any substantive effect in
limiting or otherwise construing any provision herein.

         Section 10. Inconsistent Provisions. In the event that any provision of
these by-laws is or becomes inconsistent with any provision of the certificate
of incorporation, the General Corporation Law of the State of Delaware or any
other applicable law, the provision of these by-laws shall not be given any
effect to the extent of such inconsistency but shall otherwise be given full
force and effect.

                                  ARTICLE VIII

                                   AMENDMENTS

         These by-laws may be amended, altered, or repealed and new by-laws
adopted at any meeting of the board of directors by a majority vote. The fact
that the power to adopt, amend, alter, or repeal the by-laws has been conferred
upon the board of directors shall not divest the stockholders of the same
powers.

the Corporation's Share records) to the lawful owner or holder of such Shares

Shares are offered: first, to the Corporation for redemption, by tender to the
Board; and second, to the other then-existing Shareholders of the Corporation,
in proportion to the number of Shares then owned by such other Shareholders who
desire to accept the offer. The price per Share shall be fixed by market-value
appraisal as follows: one appraiser appointed by the offerees, one appraiser
appointed by the offeror, and a third appraiser selected by the above two
appraisers; provided, however, that no such appraisers need be appointed or
chosen if the offeror and the offeree(s) mutually agree upon the purchase price
of the Shares. Each offeree, as above-designated, shall have thirty (30) days in
which to accept said offer; if such offeree does not accept said offer within
thirty (30) days, the offeree shall be deemed to have rejected the offer.

           b. The foregoing restrictions and limitations shall be imprinted on
all Share Certificates of the Corporation but may be modified, nullified or
superseded pursuant to written agreement(s) by all the Shareholders or in
accordance with the Articles of Incorporation.

           c. As to any particular Shareholder, the foregoing restrictions and
limitations shall be superseded by the terms and conditions of any Stock
Redemption Agreement or similar




                                      -14-
<PAGE>   15

Agreement entered into by the Corporation and such Shareholder to the extent the
terms and conditions of such Stock Redemption or similar Agreement are
inconsistent herewith.

           d. No Shares shall be issued, sold, offered for sale, hypothecated,
pledged, assigned, disposed of or otherwise transferred (whether by reason of
death, sale, gift, assignment, order of court, any judicial process or
otherwise) unless: (i) such Shares have been duly registered under the
Securities Act of 1933, as amended, pursuant to an effective registration
statement contemplating the transaction or transactions in which the Shares are
to be sold, offered for sale, hypothecated, pledged, assigned, disposed of, or
otherwise transferred; or (ii) both of the following conditions are satisfied:

              (1)   During the period in which securities that are part of an
                    issue are being offered and sold by the Corporation, and for
                    a period of nine (9) months from the date of the
                    Corporation's last sale of such securities, all resales of
                    any part of the Shares of the issue, by any persons, shall
                    be made only to persons resident within the State of Ohio;
                    and

              (2)   The Corporation has received the written opinion of its
                    counsel to the effect that the sale, offer for sale,
                    hypothecation, assignment, transfer, or other proposed
                    disposition of the Shares may be accomplished without such
                    registration under the Securities Act of 1933.

           e. Certificates for all the Corporation's issued Shares shall bear a
legend in substantially the following form:

              THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
              REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY
              NOT BE SOLD, OFFERED FOR SALE, HYPOTHECATED, ASSIGNED, TRANSFERRED
              OR OTHERWISE DISPOSED OF UNLESS (A) SUCH SECURITIES ARE REGISTERED
              UNDER SAID ACT; OR (B) BOTH OF THE FOLLOWING CONDITIONS ARE
              SATISFIED: (i) DURING THE PERIOD IN WHICH AN ISSUE (OF WHICH THESE
              SECURITIES ARE A PART) IS BEING OFFERED AND SOLD BY THE
              CORPORATION AND FOR A PERIOD OF NINE (9) MONTHS FROM THE DATE OF
              THE CORPORATION'S LAST SALE OF SUCH ISSUE, ALL RESALES OF ANY PART
              OF THESE SECURITIES BY ANY PERSON SHALL BE MADE ONLY TO PERSONS
              RESIDENT WITHIN THE STATE OF OHIO, AND (ii) THE CORPORATION
              RECEIVES AN OPINION OF COUNSEL SATISFACTORY TO IT THAT SUCH
              PROPOSED SALE OR OFFER OR OTHER DISPOSITION DOES NOT REQUIRE
              REGISTRATION OF SUCH SECURITIES UNDER SAID ACT.

         4.6 CAPITAL ACCOUNT. There shall be established on the books of the
Partnership a capital account ("Capital Account") for each Partner. The Capital
Account of each Partner shall be credited with the fair market value of each
Partner's Capital Contribution. The Capital Account of each Partner shall be
maintained and adjusted by the General Partner in a manner to reflect the
Partner's economic arrangement as set forth in this Agreement. The Capital
Accounts may be adjusted and maintained in the manner specified in regulations
promulgated by the United States Treasury Department, which would apply to a
partnership subject to the provisions of subchapter K of chapter 1 of the
Internal Revenue Code of 1986, as amended. If a Partner transfers all or any

accurate books of the Partnership at the Partnership's principal place of

and affairs, including those sufficient to record the allocations and
distributions provided for in Sections 7, 9 and 11.

         5.2 FISCAL YEAR. The fiscal year of the Partnership shall be the

         5.3 REPORTS.

                  (a) Within 30 days after such information is provided to the
General Partner by the Partnership's accountant with respect to each Fiscal Year
of the Partnership, the General Partner shall furnish to each person who was a
Partner at any time during such Fiscal Year all the information relating to the
Partnership which shall be necessary for the preparation by each such person of
their Federal and state income or other tax returns.

                  (b) The Partnership shall not be obligated to deliver or mail
a copy of the Partnership's Certificate of Limited Partnership, nor any
amendment or cancellation thereof, to the Limited Partners.

         5.4 TAX RETURNS. It shall be the duty of the General Partner to
prepare, or cause to be prepared, and timely file, all Federal, state and local
income tax returns and information returns, if any, which the Partnership is
required to file. All expenses incurred in connection with such tax returns and

designated by the General Partner. Withdrawals therefrom shall be made upon such
signature or signatures as the General Partner may designate. Partnership funds
shall not be commingled with those of any other person or entity.

7.       ALLOCATION OF NET INCOME AND NET LOSS.

         7.1 NET INCOME.

                  (a) Except as otherwise provided herein, the net income of the
Partnership for each Fiscal Year shall be allocated to the Partners in
accordance with their respective Percentage Interests.

                  (b) If net losses are allocated to a Partner in accordance
with the provisions of Section 7.2(b), then notwithstanding the provisions of
Section 7.1(a), net income thereafter recognized by the Partnership shall be
allocated to the Partner until such time as the net income allocated to the
Partner pursuant to this Section 7.1(b) equals the net losses theretofore
allocated to the Partner pursuant to Section 7.2(b).

         7.2 NET LOSS.

                  (a) Except as otherwise provided herein, the net loss of the
Partnership for each Fiscal Year shall be allocated to the Partners in
accordance with their respective Percentage Interests.

                  (b) Notwithstanding the provisions of Section 7.2(a), net
losses shall be allocated to those Partners which bear the economic risk of loss
for such net losses, if any Partner bears such economic risk of loss, when the
allocations under Section 7.2(a) would otherwise create or increase a deficit
balance in the Capital Accounts of the Partners.

                  (c) It is the overall intention of the Partners that all
income, losses and distributions be allocated and made to the Partners, and the
Capital Accounts of the Partners be, in proportion to their respective
Percentage Interests. Except as provided in Section 7.1(b) or 7.2(b), the
General Partner shall interpret this Agreement consistent with that overall
intention.

         7.3 ALLOCATIONS IN EVENT OF TRANSFER, ADMISSION OF NEW PARTNER, ETC. In
the event of (i) the transfer of all or any part of a Partner's Partnership
Interest (in accordance with the provisions of this Agreement), or (ii) the
admission of a new Partner at any time other than at the end of a Fiscal Year,
the transferring Partner's and new Partner's shares of the Partnership's income,
gain, loss, deductions and credits allocable to such interest, as computed both
for accounting purposes and for income tax purposes, shall be allocated between
the transferor Partner and the transferee Partner (or Partners), or the new
Partner and the other Partners, as the case may be, in the same ratio as the
number of days in such Fiscal Year before and after the date of such transfer or
admission; provided, however, that the General Partner shall have the option to
treat the periods before and after the date of such transfer, admission or
disproportionate capital contributions as separate Fiscal Years and allocate the
Partnership's net income, gain, net loss, deductions and credits


                                       4

<PAGE>   9


for each of such deemed separate Fiscal Years in accordance with the Partners'
respective interests in the Partnership for such deemed separate Fiscal Years.

8.       TAX ELECTIONS.

         8.1 TAX ELECTIONS. The General Partner shall have the authority to make
any and all tax elections to be made by the Partnership for Federal, state,
local, or foreign tax purposes. Each Partner agrees to execute any and all
necessary forms and other documents necessary to make any such tax election.

9.       DISTRIBUTIONS.

         9.1 CASH DISTRIBUTIONS. The Partnership's cash available for
distribution (as determined by the General Partner) shall be distributed at such
time or times as the General Partner shall determine. All such distributions
shall be made to the Partners in accordance with their respective Percentage
Interests as of the date of distribution.

         9.2 PROPERTY DISTRIBUTIONS. If any property of the Partnership, other
than cash, is distributed by the Partnership to a Partner (in connection with
the liquidation of the Partnership or otherwise), the fair market value of such
Property shall be used for purposes of determining the amount of such
distribution. The difference, if any, of such fair market value over (or under)
the value at which such property is carried on the books of the Partnership
shall be credited or charged to the Capital Accounts of the Partners in
accordance with the ratio in which the Partners share in the gain and loss of
the Partnership pursuant to Sections 7.1 and 7.2. The fair market value of the
property distributed shall be agreed to by the General Partner (Liquidating
Trustee in the case of a liquidating distribution) and the distributee Partner
in good faith. If any such property is distributed other than in exchange for a
Partnership Interest, it shall be distributed in the same manner as a cash
distribution.

10.      MANAGEMENT.

         10.1 MANAGEMENT.

                  (a) Control and management of the business of the Partnership
as described in Section 3 shall be vested exclusively in the General Partner
during the term of the Partnership, including its liquidation and dissolution.
Except as specifically provided for herein, the Limited Partners shall not have
any voice in, or take part in, the management of the Partnership. The Limited
Partners shall not have any authority to act for, or to assume any obligations
or responsibilities on behalf of, any other Partner or the Partnership.

                  (b) The General Partner shall have the right, power and
authority on behalf of the Partnership and in its name, without the consent of
the Limited Partners, to exercise all of the rights, powers and authority which

of indebtedness and the granting of mortgages or other security interests to
secure such indebtedness.

         10.2 STANDARD OF CARE OF GENERAL PARTNER, INDEMNIFICATION.

                  (a) 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 this Agreement and in the best interests of the
Partnership, unless they have been guilty of gross negligence or willful
misconduct.

                  (b) To the full extent permitted by the Act, the Partnership
shall indemnify the General Partner, its officers, directors and members, for,
and hold the General Partner, its officers, 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 Act, the
Partnership shall pay or reimburse reasonable expenses (including reasonable
attorneys' fees) incurred by the General Partner, its officers, directors and
member, 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, or 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 provisions of this Section 10.2(b) or the Act.

         10.3 COMPENSATION FOR SERVICES. The General Partner shall not be
entitled to compensation for its services as General Partner unless agreed to by
the Limited Partner. The General Partner shall, however, participate in the
Partnership's profit and loss, shall receive distributions pursuant to Sections
9 and 11 and shall be entitled to reimbursement from the Partnership for
expenses incurred on behalf of the Partnership as provided in Section 10.5.

         10.4 OTHER ACTIVITIES. The General Partner shall devote such of the
General Partner's time as the General Partner deems necessary to the affairs of
the Partnership's business. The General Partner and the General Partner's
Affiliates may engage in, or possess an interest in, other business ventures of
any nature and description, independently or with others, whether or not such
activities are competitive with those of the Partnership. Neither the
Partnership, nor any Partner, shall have any rights by virtue of this Agreement
in and to such independent ventures, or to the income or profits derived
therefrom. The General Partner and the General Partner's Affiliates shall not be
obligated to present any particular business opportunity of a character which,
if presented to the Partnership, could be taken by the Partnership and the
General Partner and the General Partner's Affiliates shall have the right to
take for their own account, or to recommend to others, any such particular
business opportunity. For purposes of this Agreement, the term "Affiliate" shall
mean any person, corporation, partnership, trust, limited liability company or
entity controlling (directly or indirectly), controlled by, or under common
control with, a General Partner.

         10.5 REIMBURSEMENT OF EXPENSES OF GENERAL PARTNER. Regardless of
whether any distributions are made to the Partners, the Partnership shall
reimburse the General Partner, at the General Partner's cost, for the direct
expenses which the General Partner incurs in performing services on behalf of
the Partnership, including, without limitation, costs of (i) accounting,
statistical or bookkeeping services, (ii) computing or accounting equipment and
(iii) travel, telephone, postage, legal, accounting and other expenses relating
to the operation of the business of the Partnership. Notwithstanding Section
10.3 or this Section 10.5 to the contrary, the Partnership may pay Affiliates of
the General Partner for services or the use of property provided such payments
are no less favorable to the Partnership than those that would be made to a
person that is not an Affiliate of the General Partner.

11.      DISSOLUTION.

         11.1 DISSOLUTION.

                  (a) Except as otherwise provided in the Act, the Partnership
shall dissolve upon, but not before, the first to occur of the following:

                           (1) The occurrence of an event of withdrawal with
         respect to the General Partner unless within 90 days after the
         occurrence of any such event the Limited Partner selects a successor
         general partner to replace the General Partner and agrees to continue
         the business of the Partnership; or

                           (2) The unanimous decision of the Partners to
         dissolve the Partnership.

                  (b) Dissolution of the Partnership shall be effective upon the
date on which the event giving rise to the dissolution occurs, but the
Partnership shall not terminate until the Partnership's Certificate of Limited
Partnership has been canceled and the assets of the Partnership shall have been
distributed as provided in Section 11.3. Notwithstanding dissolution of the
Partnership, prior to the liquidation and termination of the Partnership, the
business of the Partnership and the affairs of the Partners, as such, shall
continue to be governed by this Agreement.

                  (c) The Partnership shall not dissolve upon the death,
bankruptcy, adjudication of incompetency or insanity, withdrawal from or
assignment of, the interest in the Partnership of a Limited Partner. In any such
event, the General Partner shall have the right and duty to continue the
business of the Partnership under the terms of this Agreement.

         11.2 SALE OF ASSETS UPON DISSOLUTION. Following the occurrence of any
of the events set forth in Section 11.1(a), the Liquidating Trustee (referred to
in Section 11.4) shall determine whether the assets of the Partnership are to be
sold or whether all or any part of such assets are to be distributed to the
Partners in kind in dissolution of the Partnership.

         11.3 DISTRIBUTIONS UPON DISSOLUTION. Upon the dissolution of the
Partnership, the properties of the Partnership to be sold shall be liquidated in
orderly fashion and the proceeds thereof and the property to be distributed in
kind shall be distributed on or before the later to occur of (i) the


                                       7


<PAGE>   12


close of the Partnership's taxable year, or (ii) 90 days following the date of
such dissolution, as follows:

                  (a) First, to the payment and discharge of all of the
Partnership's debts and liabilities (including to Partners in accordance with
the priorities established by law), to the necessary expenses of liquidation and
to the establishment of any cash reserves which the Liquidating Trustee
determines to create in the Liquidating Trustee's sole discretion for unmatured
and/or contingent liabilities or obligations of the Partnership.

                  (b) Second, to the Partners in accordance with their
respective Percentage Interests.

         11.4 LIQUIDATING TRUSTEE. Upon the occurrence of any of the events set
forth in Section 11.1(a), the General Partner, if there is any at such time,
shall constitute the Liquidating Trustee for the Partnership. If there is no
General Partner at such time, then the Limited Partner shall select one or more
individuals to act as Liquidating Trustee for the Partnership. The Liquidating
Trustee, whether or not the General Partner, shall be subject to the same
standards, and be entitled to the same indemnification, as the General Partner
pursuant to Section 10.2.

         11.5 LIQUIDATION OF A PARTNER'S INTEREST. If a Partner's Partnership
Interest is to be liquidated by agreement between the Partnership and such
Partner (the Partnership being under no obligation to do so), the Partner shall
be entitled to receive in liquidation an amount equal to the amount determined
by any such agreement. Net income or net loss shall be allocated to the Partner
whose interest is to be liquidated in accordance with Section 7.3 and the
Capital Accounts of the Partners shall be adjusted by the General Partner to
reflect the liquidation.

12.      WITHDRAWAL, ASSIGNMENT, ADDITION OF PARTNERS AND MERGER

         12.1 ASSIGNMENT OF LIMITED PARTNER'S INTEREST. A Limited Partner may
not freely sell, assign, transfer, pledge, hypothecate, encumber or otherwise
dispose of its Partnership Interest without the consent of the General Partner
which consent may be withheld in the sole and absolute discretion of the General
Partner.

         12.2 SUBSTITUTE LIMITED PARTNER. No assignee of a Limited Partner's
Partnership Interest shall have the right to become a substitute Limited Partner
unless all of the following conditions are satisfied:

                  (a) except in the case of death or adjudication of
incompetency or insanity, the fully executed and acknowledged written instrument
of assignment has been filed with the Partnership setting forth the intention of
the assignor that the assignee become a substitute Limited Partner in place of
the assignor with respect to the Partnership Interest assigned;

                  (b) the assignor and assignee execute and acknowledge such
other instruments as the General Partner deems necessary or desirable to effect
such admission, including, but not


                                       8

<PAGE>   13


limited to, the written acceptance and adoption by the assignee of the
provisions of this Agreement; and

                  (c) the General Partner has consented to the assignment and
substitution, which shall be in the General Partner's sole and absolute
discretion.

         12.3 DEATH, INCOMPETENCY, ETC. OF A LIMITED PARTNER. In the event of
the death, bankruptcy or adjudication of incapacity or incompetence of a Limited
Partner, the personal representative, heirs, legatees and devisees of the
Limited Partner, as the case may be, shall have all of the rights of an assignee
of a Limited Partner interest, but shall not become a substitute Limited Partner
unless the provisions of Section 12.2 have been complied with. In all of the
above cases, the successor-in-interest to the Limited Partner shall not have a
right to demand payment with respect to the Partnership Interest.

         12.4 ASSIGNMENT OF GENERAL PARTNER'S INTEREST. The General Partner may
not sell, assign, transfer, pledge, hypothecate, encumber or otherwise dispose
of its Partnership Interest, nor withdraw from the Partnership, without the
prior written consent of all of the Limited Partners.

         12.5 ADMISSION OF NEW PARTNER. Except as otherwise specifically
provided for herein, no new Partner may be admitted to the Partnership without
the consent of all of the Partners. For purposes of this Section 12.5, a
substitute Limited Partner shall not be considered a "new Partner."

         12.6 MERGER. The Partnership may merge with any other limited
partnership or other entity pursuant to the applicable provisions of the Act in
the sole discretion of the General Partner.

                          IRWIN TELECOM HOLDINGS, INC.

                                   ARTICLE I.

                                  STOCKHOLDERS


         SECTION 1.1 PLACE OF MEETINGS. Meetings of stockholders shall be held
at the place, either within or without the State of Delaware, as may be
designated by resolution of the Board of Directors from time to time.

         SECTION 1.2 ANNUAL MEETINGS. Annual meetings of stockholders shall be
held at the time and place designated by the Board of Directors of the
corporation, at which time they shall elect a Board of Directors and transact
any other business as may properly be brought before the meeting.

         SECTION 1.3 SPECIAL MEETINGS. Special meetings of stockholders for any
purpose or purposes may be called at any time by the Board of Directors, or by a
committee of the Board of Directors which has been duly designated by the Board
of Directors and whose powers and authority, as expressly provided in a
resolution of the Board of Directors, include the power to call such meetings,
but such special meetings may not be called by any other person or persons.

         SECTION 1.4 NOTICE OF MEETINGS. Whenever stockholders are required or
permitted to take any action at a meeting, a written notice of the meeting shall
be given which shall state the place, date and hour of the meeting, and, in the
case of a special meeting, the purpose or purposes for which the meeting is
called. Unless otherwise provided by law, the Certificate of Incorporation of
these Bylaws, the written notice of any meeting shall be given no less than ten
(10) nor more than sixty (60) days before the date of the meeting to each
stockholder entitled to vote at such meeting. If mailed, such notice shall be
deemed to be given when deposited in the mail, postage prepaid, directed to the
stockholder at his or her address as it appears on the records of the
corporation.

         SECTION 1.5 ADJOURNMENTS. Any meeting of stockholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business which
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

         SECTION 1.6 QUORUM. Except as otherwise provided by law, the
Certificate of Incorporation or these Bylaws, at each meeting of stockholders
the presence in person or by proxy of the holders of shares of stock having a
majority of the votes which could be cast by the holders


                                       1
<PAGE>   3


of all outstanding shares of stock entitled to vote at the meeting shall be
necessary and sufficient to constitute a quorum. In the absence of a quorum, the
stockholders so present may, by majority vote, adjourn the meeting from time to
time in the manner provided in Section 1.5 of these Bylaws until a quorum shall
attend. Shares of its own stock belonging to the corporation or to another
corporation, if a majority of the shares entitled to vote in the election of
directors of such other corporation is held, directly or indirectly, by the
corporation, shall neither be entitled to vote nor be counted for quorum
purposes; provided, however, that the foregoing shall not limit the right of the
corporation to vote stock, including but not limited to its own stock, held by
it in a fiduciary capacity.

         SECTION 1.7 ORGANIZATION. Meetings of stockholders shall be presided
over by the Chairman of the Board, if any, or in his or her absence by the Vice
Chairman of the Board, if any, or in his or her absence by the President, or in
his or her absence by a Vice President, or in the absence of the foregoing
persons by a chairman designated by the Board of Directors, or in the absence of
such designation by a chairman chosen at the meeting. The Secretary shall act
as secretary of the meeting, but in his or her absence the chairman of the
meeting may appoint any person to act as secretary of the meeting.

         SECTION 1.8 VOTING; PROXIES. Except as otherwise provided by the
Certificate of Incorporation, each stockholder entitled to vote at any meeting
of stockholders shall be entitled to one vote for each share of stock held by
him which has voting power upon the matter in question. Each stockholder
entitled to vote at a meeting of stockholders may authorize another person or
persons to act for him by proxy, but no such proxy shall be voted or acted upon
after three (3) years from its date, unless the proxy provides for a longer
period. A duly executed proxy shall be irrevocable if it states that it is
irrevocable and if, and only as long as, it is coupled with an interest
sufficient in law to support an irrevocable power. A stockholder may revoke any
proxy which is not irrevocable by attending the meeting and voting in person or
by filing an instrument in writing revoking the proxy or another duly executed
proxy bearing a later date with the Secretary of the corporation. Voting at
meetings of stockholders need not be by written ballot and need not be conducted
by inspectors of election unless so determined by the holders of shares of stock
having a majority of the votes which could be cast by the holders of all
outstanding shares of stock entitled to vote thereon which are present in person
or by proxy at such meeting. At all meetings of stockholders for the election of
directors a plurality of the votes cast shall be sufficient to elect. All other
elections and questions shall, unless otherwise provided by law, the Certificate
of Incorporation or these Bylaws, be decided by the vote of the holders of
shares of stock having a majority of the votes which could be cast by the
holders of all shares of stock entitled to vote thereon which are present in
person or represented by proxy at the meeting.

         SECTION 1.9 FIXING DATE FOR DETERMINATION OF STOCKHOLDERS OF RECORD. In
order that the corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors and which record date: (1) in the case of determination of
stockholders


                                        2

<PAGE>   4


entitled to vote at any meeting of stockholders or adjournment thereof, shall,
unless otherwise required by law, not be more than sixty (60) nor less than ten
(10) days before the date of such meeting; (2) in the case of determination of
stockholders entitled to express consent to corporate action in writing without
a meeting, shall not be more than ten (10) days from the date upon which the
resolution fixing the record date is adopted by the Board of Directors; and (3)
in the case of any other action, shall not be more than sixty (60) days prior to
such other action. If no record date is fixed: (1) the record date for
determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the day next preceding the day
on which notice is given, or, if notice is waived, at the close of business on
the day next preceding the day on which the meeting is held; (2) the record date
for determining stockholders entitled to express consent to corporate action in
writing without a meeting when no prior action of the Board of Directors is
required by law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
corporation in accordance with applicable law, or, if prior action by the Board
of Directors is required by law, shall be at the close of business on the day on
which the Board of Directors adopts the resolution taking such prior action; and
(3) the record date for determining stockholders for any other purpose shall be
at the close of business on the day on which the Board of Directors adopts the
resolution relating thereto. A determination of stockholders of record entitled
to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the meeting; provided, however, that the Board of Directors may
fix a new record date for the adjourned meeting.

         SECTION 1.10 LIST OF STOCKHOLDERS ENTITLED TO VOTE. The Secretary shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any stockholder who is present. Upon the willful
neglect or refusal of the directors to produce such a list at any meeting for
the election of directors, they shall be ineligible for election to any office
at such meeting. The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list of stockholders or
the books of the corporation, or to vote in person or by proxy at any meeting of
stockholders.

         SECTION 1.11 ACTION BY CONSENT OF STOCKHOLDERS. Unless otherwise
restricted by the Certificate of Incorporation, any action required or permitted
to be taken at any annual or special meeting of the stockholders may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing

         SECTION 2.1 NUMBER; QUALIFICATIONS. The Board of Directors shall
consist of one or more members, the number thereof to be determined from time to
time by resolution of the Board of Directors. The number of directors which
shall comprise the initial Board of Directors shall be that number set forth in
the Certificate of Incorporation. Directors need not be stockholders.

         SECTION 2.2 ELECTION; RESIGNATION; REMOVAL; VACANCIES. The Board of
Directors shall be elected at each annual meeting of stockholders and each
director shall hold office for a term of one (1) year or until his or her
successor is elected and qualified. Any director may resign at any time upon
written notice to the corporation. Any newly created directorship or any vacancy
occurring in the Board of Directors for any cause may be filled by a majority of
the remaining members of the Board of Directors, although such majority is less
than a quorum, or by a plurality of the votes cast at a meeting of stockholders,
and each director so elected shall hold office until the expiration of the term
of office of the director whom he has replaced or until his or her successor is
elected and qualified.

         SECTION 2.3 REGULAR MEETINGS. Regular meetings of the Board of
Directors may be held at such places within or without the State of Delaware and
at such times as the Board of Directors may from time to time determine, and if
so determined, notices thereof need not be given.

         SECTION 2.4 SPECIAL MEETINGS. Special meetings of the Board of
Directors may be held at any time or place within or without the State of
Delaware whenever called by the President, any Vice President, the Secretary, or
by any member of the Board of Directors. Notice of a special meeting of the
Board of Directors shall be given by the person or persons calling the meeting
at least twenty-four (24) hours before the special meeting.

         SECTION 2.5 TELEPHONIC MEETINGS PERMITTED. Members of the Board of
Directors, or any committee designated by the Board of Directors, may
participate in a meeting thereof by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
bylaw shall constitute presence in person at such meeting.

         SECTION 2.6 QUORUM; VOTE REQUIRED FOR ACTION. At all meetings of the
Board of Directors a majority of the whole Board of Directors shall constitute a
quorum for the transaction of business. Except in cases in which the Certificate
of Incorporation or these Bylaws otherwise provide, the vote of a majority of
the directors present at a meeting at which a quorum is present shall be the act
of the Board of Directors.

         SECTION 2.7 ORGANIZATION. Meetings of the Board of Directors shall be
presided over by the Chairman of the Board, if any, or in his or her absence by
the Vice Chairman of the Board, if any, or in his or her absence by the
President, or in their absence by a chairman chosen at the meeting. The
Secretary shall act as secretary of the meeting, but in his or her absence the
chairman of the meeting may appoint any person to act as secretary of the
meeting.

         SECTION 2.8 INFORMAL ACTION BY DIRECTORS. Unless otherwise restricted
by the Certificate of Incorporation or these Bylaws, any action required or
permitted to be taken at any meeting of the Board of Directors, or of any
committee thereof, may be taken without a meeting if all members of the Board of
Directors or such committee, as the case may be, consent thereto in writing, and
the writing or writings are filed with the minutes of proceedings of the Board
of Directors or such committee.


                                  ARTICLE III.

                                   COMMITTEES

         SECTION 3.1 COMMITTEES. The Board of Directors may, by resolution
passed by a majority of the whole Board of Directors, designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The Board of Directors may designate one or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee. In the absence or disqualification of a
member of the committee, the member or members thereof present at any meeting
and not disqualified from voting, whether or not he or they constitute a quorum,
may unanimously appoint another member of the Board of Directors to act at the
meeting in place of any such absent or disqualified member. Any such committee,
to the extent permitted by law and to the extent provided in the resolution of
the Board of Directors, shall have and may exercise all the powers and authority
of the Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
pages which may require it.

         SECTION 3.2 COMMITTEE RULES. Unless the Board of Directors otherwise
provides, each committee designated by the Board of Directors may make, alter
and repeal rules for the conduct of its business. In the absence of such rules
each committee shall conduct its business in the same manner as the Board of
Directors conducts its business pursuant to Article II of these Bylaws.


                                   ARTICLE IV.

                                    OFFICERS

         SECTION 4.1 EXECUTIVE OFFICERS; ELECTION; QUALIFICATIONS; TERM OF
OFFICE; RESIGNATION; REMOVAL; VACANCIES. The Board of Directors shall elect a
President and Secretary, and it may, if it so determines, choose a Chairman of
the Board and a Vice Chairman of the Board from among its members. The Board of
Directors may also elect one or more Vice Presidents, one or more Assistant
Secretaries, a Treasurer, one or more Assistant Treasurers, and such other
officers as the Board of Directors deems necessary. Each such officer shall hold
office until the first meeting of the Board of Directors after the annual
meeting of stockholders next succeeding his or her election, and


                                       5
<PAGE>   7


until his or her successor is elected and qualified or until his or her earlier
resignation or removal. Any officer may resign at any time upon written notice
to the corporation. The Board of Directors may remove any officer with or
without cause at any time, but such removal shall be without prejudice to the
contractual rights of such officer, if any, with the corporation. Any number of
offices may be held by the same person. Any vacancy occurring in any office of
the corporation by death, resignation, removal or otherwise may be filled for
the unexpired portion of the term by the Board of Directors at any regular or
special meeting.

         SECTION 4.2 POWERS AND DUTIES OF EXECUTIVE OFFICERS. The officers of
the corporation shall have such powers and duties in the management of the
corporation as may be prescribed by the Board of Directors and, to the extent
not so provided, as generally pertain to their respective officers, subject to
the control of the Board of Directors. The Board of Directors may require any
officer, agent or employee to give security for the faithful performance of his
or her duties.


                                   ARTICLE V.

                                      STOCK

         SECTION 5.1 CERTIFICATES. Every holder of stock shall be entitled to
have a certificate signed by or in the name of the corporation by the Chairman
or Vice Chairman of the Board of Directors, if any, or the President or a Vice
President, and by the Treasurer or an Assistant Treasurer, or the Secretary or
an Assistant Secretary, of the corporation, certifying the number of shares
owned by him in the corporation. Any of or all the signatures on the certificate
may be a facsimile. In case any officer, transfer agent, or registrar who has
signed or whose facsimile signature has been placed upon a certificate shall
have ceased to be such officer, transfer agent, or registrar before such
certificate is issued, it may be issued by the corporation with the same effect
as if he were such officer, transfer agent, or registrar at the date of issue.

         SECTION 5.2 LOST, STOLEN OR DESTROYED STOCK CERTIFICATES; ISSUANCE OF
NEW CERTIFICATES. The corporation may issue a new certificate of stock in the
place of any certificate theretofore issued by it, alleged to have been lost,
stolen or destroyed, and the corporation may require the owner of the lost,
stolen or destroyed certificate, or his or her legal representative, to give the
corporation a bond sufficient to indemnify it against any claim that may be made
against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate.


                                   ARTICLE VI.

                                 INDEMNIFICATION

         SECTION 6.1 RIGHT TO INDEMNIFICATION. The corporation shall indemnify
and hold harmless, to the fullest extent permitted by applicable law as it
presently exists or may hereafter be amended, any person who was or is made or
is threatened to be made a party or is otherwise involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative


                                       6

(a "proceeding"), by reason of the fact that he or she or a person for whom he
or she is the legal representative, is or was a director or officer of the
corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust, enterprise or nonprofit entity, including service with
respect to employee benefit plans (an "indemnitee"), against all liability and
loss suffered and expenses (including attorneys' fees) reasonably incurred by
such indemnitee. The corporation shall be required to indemnify an indemnitee in
connection with a proceeding (or part thereof) initiated by such indemnitee only
if the initiation of such proceeding (or part thereof) by the indemnitee was
authorized by the Board of Directors of the corporation.

         SECTION 6.2 PREPAYMENT OF EXPENSES. The corporation shall pay the
expenses (including attorneys' fees) incurred by an indemnitee in defending any
proceeding in advance of its final disposition, provided, however, that the
payment of expenses incurred by a director or officer in advance of the final
disposition of the proceeding shall be made only upon receipt of an undertaking
by the director or officer to repay all amounts advanced if it should be
ultimately determined that the director or officer is not entitled to be
indemnified under this Article or otherwise.

         SECTION 6.3 CLAIMS. If a claim for indemnification or payment of
expenses under this Article is not paid in full within sixty (60) days after a
written claim therefor by the indemnitee has been received by the corporation,
the indemnitee may file suit to recover the unpaid amount of such claim and, if
successful in whole or in part, shall be entitled to be paid the expenses of
prosecuting such claim. In any such action the corporation shall have the burden
of proving that the indemnitee was not entitled to the requested indemnification
or payment of expenses under applicable law.

         SECTION 6.4 NONEXCLUSIVITY OF RIGHTS. The rights conferred on any
person by this Article VI shall not be exclusive of any other rights which such
person may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, these By-laws, agreement, vote of stockholders or
disinterested directors or otherwise.

         SECTION 6.5 OTHER INDEMNIFICATION. The corporation's obligation, if
any, to indemnify any person who was or is serving at its request as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, enterprise, or nonprofit entity shall be reduced by any amount such
person may collect as indemnification from such other corporation, partnership,
joint venture, trust, enterprise or nonprofit enterprise.

         SECTION 6.6 AMENDMENT OR REPEAL. Any repeal or modification of the
foregoing provisions of this Article VI shall not adversely affect any right or
protection hereunder of any person in respect of any act or omission occurring
prior to the time of such repeal or modification.

         SECTION 7.1 FISCAL YEAR. The fiscal year of the corporation shall be
determined by resolution of the Board of Directors.

         SECTION 7.2 SEAL. The corporate seal shall have the name of the
corporation inscribed thereon and shall be in such form as may be approved from
time to time by the Board of Directors.

         SECTION 7.3 WAIVER OF NOTICE OF MEETINGS OF STOCKHOLDERS, DIRECTORS AND
COMMITTEES. Any written waiver of notice, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of any
regular or special meeting of the stockholders, directors, or members of a
committee of directors need be specified in any written waiver of notice.

         SECTION 7.4 INTERESTED DIRECTORS; QUORUM. No contract or transaction
between the corporation and one or more of its directors or officers, or between
the corporation and any other corporation, partnership, association, or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or committee thereof which
authorizes the contract or transaction, or solely because his, her or their
votes are counted for such purpose, if: (1) the material facts as to his or her
relationship or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or the committee, and the Board of Directors
or committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (2) the material facts as to
his or her relationship or interest and as to the contract or transaction are
disclosed or are known to the stockholders entitled to vote thereon, and the
contract or transaction is specifically approved in good faith by vote of the
stockholders; or (3) the contract or transaction is fair as to the corporation
as of the time it is authorized, approved or ratified by the Board of Directors,
a committee thereof, or the stockholders. Common or interested directors may be
counted in determining the presence of a quorum at a meeting of the Board of
Directors or of a committee which authorizes the contract or transaction.

         SECTION 7.5 FORM OF RECORDS. Any records maintained by the corporation
in the regular course of its business, including its stock ledger, books of
account, and minute books, may be kept on, or be in the form of, punch cards,
magnetic tape, photographs, microphotographs, or any other information storage
device, provided that the records so kept can be converted into clearly legible
form within a reasonable time. The corporation shall so convert any records so
kept upon the request of any person entitled to inspect the same.

         SECTION 7.6 AMENDMENT OF BYLAWS. These Bylaws may be altered or
repealed, and new Bylaws made by the Board of Directors, but the stockholders
may make additional bylaws and may alter and repeal any bylaws whether adopted
by them or otherwise.

<PAGE>   9

the need to calculate the Consolidated Fixed Charge Coverage Ratio (the
"Transaction Date") to Consolidated Fixed Charges of NATG for such Four Quarter
Period. In addition to, and without limitation of, the foregoing, 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 such
calculation to (i) the Incurrence or repayment of any Indebtedness of NATG or
any of its Restricted Subsidiaries (and the application of the proceeds thereof)
giving rise to the need to make such calculation and any Incurrence or repayment
of other Indebtedness (and the application of the proceeds thereof), other than
the Incurrence or repayment of Indebtedness in the ordinary course of business
for working capital purposes pursuant to working capital facilities (including
revolving credit facilities), 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 Transaction Date, as if such Incurrence or repayment, as the case may be
(and the application of the proceeds thereof), occurred on the first day of the
Four Quarter Period and (ii) any Asset Sales or other dispositions or Asset
Acquisitions (including, without limitation, any Asset Acquisition giving rise
to the need to make such calculation as a result of NATG or one of its
Restricted Subsidiaries (including any Person who becomes a Restricted
Subsidiary as a result of the Asset Acquisition) Incurring Indebtedness and also
including any Consolidated EBITDA (provided, that such Consolidated EBITDA shall
be included only to the extent includable pursuant to the definition of
"Consolidated Net Income" or to the extent it is excluded pursuant to clause
(ii) of the definition of "Consolidated Net Income") and shall be calculated on
a pro forma basis with respect to any Asset Acquisition taking into account the
Pro Forma Adjustments, if any, resulting from such 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 thereto)
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 Transaction Date, as if
such 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 such guaranteed Indebtedness as if NATG or such
Restricted Subsidiary had directly incurred or otherwise assumed such guaranteed
Indebtedness (calculated to avoid duplication). Furthermore, in calculating
"Consolidated Fixed Charges" for purposes of determining the denominator (but
not the numerator) of this "Consolidated Fixed Charge Coverage Ratio," (1)
interest on outstanding Indebtedness determined on a fluctuating basis as of the
Transaction Date and which will continue to be so determined thereafter shall be
deemed to have accrued at a fixed rate per annum equal to the rate of interest
on such Indebtedness in effect on the Transaction Date, (2) if interest on any
Indebtedness actually incurred on the Transaction Date may optionally be

                                 THE SECURITIES

         Section 2.1 Form and Dating. The Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit A.
The Securities may have notations, legends or endorsements required by law,
stock exchange rule or usage. The Issuers shall approve the form of the
Securities and any notation, legend or endorsement on them. Each Security shall
be dated the date of its issuance and show the date of its authentication. Each
Security shall have an executed Guarantee from each of the Guarantors endorsed
thereon substantially in the form of Exhibit E.

         The terms and provisions contained in the Securities and the Guarantees
shall constitute, and are hereby expressly made, a part of this Indenture and,
to the extent applicable, the Issuers, the Guarantors and the Trustee, by their
execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby. Securities offered and sold to QIBs in
reliance on Rule 144A, Securities offered and sold in reliance on Regulation S

Guarantors endorsed thereon) and authenticated by the Trustee as hereinafter
provided and shall bear the legends set forth in Exhibit B. Securities initially
offered and sold in offshore transactions pursuant to Regulation S under the
Securities Act shall initially be issued in the form of a temporary Global

Distribution Compliance Period, and upon receipt by the Trustee of the
certification required by Regulation S under the Securities Act, the Temporary
Reg. S Global Security shall be exchanged for the Regulation S Global Security
in equal principal amount. The aggregate principal amount of the Global

provided.

         Securities issued in exchange for interests in a Global Security
pursuant to Section 2.16 may be issued in the form of permanent certificated
Securities in registered form in substantially the form set forth in Exhibit A

         Section 2.2 Execution and Authentication. Two Officers, or an Officer
and an Assistant

                                      -28-


<PAGE>   33

Secretary, shall sign, or one Officer shall sign and one Officer or an Assistant
Secretary (each of whom shall, in each case, have been duty authorized by all
requisite limited liability company or corporate actions, as the case may be)
shall attest to, the Securities for each of the Issuers by manual or facsimile
signature.

         If an Officer whose signature is on a Security or Guarantee, as the
case may be, was an Officer at the time of such execution but no longer holds
that office at the time the Trustee authenticates the Security, the Security or
such Guarantee shall nevertheless be valid.

         A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

         The Trustee shall authenticate (i) Initial Securities for original
issue in an aggregate principal amount not to exceed $300.0 million upon a
written order of the Issuers, provided that the aggregate principal amount of
Initial Securities issued on the Issue Date shall not exceed $150.0 million,
provided, further, that in connection with any Initial Securities originally
issued after the Issue Date, NATG complies with Section 4.4, (ii) Private
Exchange Securities from time to time only in exchange for a like principal
amount of the same type of Initial Securities in accordance with the terms of a
Registration Rights Agreement and (iii) Unrestricted Securities from time to
time (A) in exchange for a like principal amount of Initial Securities or a like
principal amount of Private Exchange Securities or (B) as the Issuers may
determine in accordance with this Indenture, in each case upon a written order
of each Issuer. Each such order shall specify the amount of Securities to be
authenticated and the date on which the Securities are to be authenticated. The
aggregate principal amount of Securities outstanding at any time may not exceed
$300.0 million, except as provided in Section 2.7.

         In the event that the Company shall issue and the Trustee shall
authenticate any Securities issued under this Indenture subsequent to the Issue
Date pursuant to clauses (i) and (iii) of the first sentence of the immediately
preceding paragraph, the Company shall use its reasonable efforts to obtain the
same "CUSIP" number for such Securities as is printed on the Securities
outstanding at such time.

         Notwithstanding the foregoing, all Securities issued under this
Indenture shall vote and consent together on all matters (as to which any of
such Securities may vote or consent) as one class and no series of Securities
will have the right to vote or consent as a separate class on any matter.

         The Trustee may appoint an authenticating agent reasonably acceptable
to the Issuers to authenticate Securities. Unless otherwise provided in the
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with the Issuers and Affiliates of the Issuers.

         The Securities shall be issuable only in fully registered form without
coupons in denominations of $1,000 and integral multiples thereof.

         Section 2.3 Registrar and Paying Agent. The Issuers shall maintain an
office or agency in the Borough of Manhattan, The City of New York, where (a)
Securities may be presented or surrendered for registration of transfer or for
exchange ("Registrar"), (b) Securities may be presented or surrendered for
payment ("Paying Agent") and (c) notices and demands to or upon the Issuers in
respect of the Securities and this Indenture may be served. The Issuers may also
from time to time designate one or more other offices or agencies where the
Securities may be presented or surrendered for any or all such purposes and may
from time to time rescind such designations; provided, that no such designation
or rescission shall in any manner relieve the Issuers of their obligation to
maintain an office or agency in the Borough of Manhattan, The City of New York,
for such purposes. The Issuers may act as Registrar or Paying Agent except that
for the purposes of Articles Three and Eight and Sections 4.15 and 4.16, neither
the Issuers nor any Affiliate of the Issuers shall act as Paying Agent. The
Registrar shall keep a register of the Securities and of their transfer and
exchange. The Issuers, upon notice to the Trustee, may have one or more
co-Registrars and one or more additional paying agents reasonably acceptable to
the Trustee. The term "Paying Agent" includes any additional paying agent. The
Issuers initially appoint the Trustee as Registrar and Paying Agent until such
time as the Trustee has resigned or a successor has been appointed.

         The Issuers shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which agreement shall implement the
provisions of this Indenture that relate to such Agent. The Issuers shall notify
the Trustee, in advance, of the name and address of any such Agent. If the
Issuers fail to maintain a Registrar or Paying Agent, the Trustee shall act as
such.

         Section 2.4 Paying Agent To Hold Assets in Trust. The Issuers shall
require each Paying Agent other than the Trustee to agree in writing that,
subject to Article Ten and Article Twelve, each Paying Agent shall hold in trust
for the benefit of Holders or the Trustee all assets held by the Paying Agent
for the payment of principal of, or interest on, the Securities (whether such
assets have been distributed to it by the Issuers or any other obligor on the
Securities), and shall notify the Trustee of any Default by the Issuers (or any
other obligor on the Securities) in making any such payment. If an Issuer or an
Affiliate of an Issuer acts as Paying Agent, it shall segregate such assets and
hold them as a separate trust fund. The Issuers at any time may require a Paying
Agent to distribute all assets held by it to the Trustee and account for any
assets disbursed and the Trustee may at any time during the continuance of any
payment default, upon written request to a Paying Agent, require such Paying
Agent to distribute all assets held by it to the Trustee and to account for any
assets distributed. Upon distribution to the Trustee of all assets that shall
have been delivered by the Issuers to the Paying Agent, the Paying Agent shall
have no further liability for such assets.

         Section 2.5 Holder Lists. The Trustee shall preserve in as current a
form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders. If the Trustee is not the Registrar, the Issuers
shall furnish to the Trustee on or before each Interest Payment Date and at such
other times as the Trustee may request in writing a list in such form and as of
such date as the Trustee may reasonably require of the names and addresses of
Holders, which list may be conclusively relied upon by the Trustee.

         Section 2.6 Transfer and Exchange. Subject to Sections 2.15 and 2.16,
when Securities are presented to the Registrar or a co-Registrar with a request
to register the transfer of such Securities or to exchange such Securities for
an equal principal amount of Securities of other authorized denominations, the
Registrar or co-Registrar shall register the transfer or make the exchange as
requested if its requirements for such transaction are met; provided, that the
Securities surrendered for transfer or exchange shall be duly endorsed or
accompanied by a written instrument of transfer in form reasonably satisfactory
to the Issuers and the Registrar or co-Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing. To permit registrations of
transfers and exchanges, the Issuers shall execute and the Trustee shall
authenticate Securities at the Registrar's or co-Registrar's request. No service
charge shall be made for any registration of transfer or exchange, but the
Issuers may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such
tax or charge payable upon exchanges or transfers pursuant to Sections 2.10,
3.6, 4.15, 4.16 or 9.6). The Registrar or co-Registrar shall not be required to
register the transfer of or exchange of any Security (i) during a period
beginning at the opening of business 15 days before the mailing of a notice of
redemption of Securities and ending at the close of business on the day of such
mailing, (ii) selected for redemption in whole or in part pursuant to Article
Three, except the unredeemed portion of any Security being redeemed in part, and
(iii) during a Change of Control Offer or an Net Proceeds Offer if such Security
is tendered pursuant to such Change of Control Offer or Net Proceeds Offer and
not withdrawn.

         Any Holder of a beneficial interest in a Global Security shall, by
acceptance of such beneficial interest, agree that transfers of beneficial
interests in such Global Securities may be effected only through a book-entry
system maintained by the Holder of such Global Security (or its agent), and that
ownership of a beneficial interest in the Security shall be required to be
reflected in a book-entry system.

         Section 2.7 Replacement Securities. If a mutilated Security is
surrendered to the Trustee or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Issuers shall issue
and the Trustee shall authenticate a replacement Security if the Trustee's
requirements for replacement of Securities are met. If required by the Trustee
or the Issuers, such Holder must provide an indemnity bond or other indemnity,
sufficient in the reasonable judgment of both the Issuers and the Trustee, to
protect the Issuers, the Trustee or any Agent from any loss which any of them
may suffer if a Security is replaced. The Issuers may charge such Holder for
their reasonable out-of-pocket expenses in replacing a Security pursuant to this
Section 2.7, including reasonable fees and expenses of counsel.

         Every replacement Security is an additional obligation of the Issuers
and every replacement Guarantee shall constitute an additional obligation of the
Guarantors.

         Section 2.8 Outstanding Securities. Securities outstanding at any time
are all the Securities that have been authenticated by the Trustee except those
cancelled by it, those delivered to it for cancellation and those described in
this Section 2.8 as not outstanding. A Security does not cease to be outstanding
because the Issuers, the Guarantors or any of their respective Affiliates holds
such Security (subject to the provisions of Section 2.9).



                                      -31-




<PAGE>   36

         If a Security is replaced pursuant to Section 2.7 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide protected purchaser. A mutilated Security ceases to be
outstanding upon surrender of such Security and replacement thereof pursuant to
Section 2.7. If the principal amount of any Security is considered paid under
Section 4.1, it ceases to be outstanding and interest ceases to accrue.

         If on a Redemption Date or the Maturity Date the Paying Agent (other
than Parent, an Issuer or any of their respective Affiliates) holds U.S. Legal
Tender or U.S. Government Obligations sufficient to pay all of the principal and
interest due on the Securities payable on that date, then on and after that date
such Securities shall cease to be outstanding and interest on them shall cease
to accrue.

         Section 2.9 Treasury Securities. In determining whether the Holders of
the required principal amount of Securities have concurred in any direction,
waiver or consent, Securities owned by Parent, any of its Subsidiaries or any of
their respective Affiliates shall be disregarded, except that, for the purposes
of determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities that the Trustee knows or has
reason to know are so owned shall be disregarded.

         Section 2.10 Temporary Securities. Until definitive Securities are
ready for delivery, the Issuers may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Issuers reasonably
consider appropriate for temporary Securities. Without unreasonable delay, the
Issuers shall prepare and the Trustee shall authenticate definitive Securities
in exchange for temporary Securities. Until such exchange, temporary Securities
shall be entitled to the same rights, benefits and privileges as definitive
Securities. Notwithstanding the foregoing, so long as the Securities are
represented by a Global Security, such Global Security may be in typewritten
form. Notwithstanding the foregoing, this Section 2.10 shall not affect the
Issuers' obligations with respect to the Temporary Reg. S Global Security set
forth in Section 2.1.

         Section 2.11 Cancellation. An Issuer at any time may deliver Securities
to the Trustee for cancellation. The Registrar and the Paying Agent shall
forward to the Trustee any Securities surrendered to them for transfer, exchange
or payment. The Trustee, or at the direction of the Trustee, the Registrar or
the Paying Agent (other than Parent, an Issuer or any of their respective
Affiliates), and no one else, shall cancel and, at the written direction of the
Issuers, shall dispose of all Securities surrendered for transfer, exchange,
payment or cancellation. Subject to Section 2.7, the Issuers may not issue new
Securities to replace Securities that they have paid or delivered to the Trustee
for cancellation. If any Issuer or any Guarantor shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction
of the Indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation pursuant to this Section 2.11.

         Section 2.12 Defaulted Interest. If the Issuers default in a payment of
interest on the Securities, they shall, unless the Trustee fixes another record
date pursuant to Section 6.10, pay the defaulted interest, plus (to the extent
lawful) any interest payable on the defaulted interest, in any lawful manner.
The Issuers may pay the defaulted interest to the persons who are Holders on a
subsequent special record date, which date shall be the fifteenth day next
preceding the date fixed by the Issuers for the payment of defaulted interest or
the next succeeding Business Day if such date is not a Business Day. At least 15
days before any such subsequent special record date, the Issuers shall mail to
each Holder, with a copy to the Trustee, a notice that states the subsequent
special record date, the payment date and the amount of defaulted interest, and
interest payable on such defaulted interest, if any, to be paid.

         Section 2.13 CUSIP Number. The Issuers in issuing the Securities shall
use "CUSIP" numbers, and if so, the Trustee shall use such CUSIP numbers in
notices of redemption or exchange as a convenience to Holders; provided, that
any such notice may state that no representation is made as to the correctness
or accuracy of the CUSIP numbers printed in the notice or on the Securities, and
that reliance may be placed only on the other identification numbers printed on
the Securities.

         Section 2.14 Deposit of Moneys. Prior to 11:00 a.m. New York City time

deposited with the Paying Agent in immediately available funds money sufficient
to make cash payments, if any, due on such Interest Payment Date, Maturity Date,
Redemption Date, Change of Control Payment Date and Net Proceeds Offer Payment
Date, as the case may be, in a timely manner which permits the Paying Agent to
remit payment to the Holders on such Interest Payment Date, Maturity Date,
Redemption Date, Change of Control Payment Date and Net Proceeds Offer Payment
Date, as the case may be.

                                  ARTICLE THREE

                                   REDEMPTION

         Section 3.1 Notices to Trustee. If the Issuers elect to redeem
Securities pursuant to Section 3.7, they shall notify the Trustee in writing of
the Redemption Date, the Redemption Price and the principal amount of Securities
to be redeemed. The Issuers shall give notice of redemption to the Paying Agent
and Trustee at least 30 days but not more than 60 days before the Redemption
Date (unless a shorter notice shall be agreed to by the Trustee in writing),
together with an Officers' Certificate of each of them stating that such
redemption will comply with the conditions contained herein.

         Section 3.2 Selection of Securities To Be Redeemed. In the event that
less than all of the Securities are to be redeemed at any time, selection of
such Securities for redemption will be made by the Trustee in compliance with
the requirements of the principal national securities exchange, if any, on which
such Securities are listed or, if such Securities are not then listed on a
national securities exchange, on a pro rata basis, by lot or by such method as
the Trustee shall deem fair and appropriate; provided, that no Securities of a
principal amount of $1,000 or less shall be redeemed in part; and provided,
further, that if a partial redemption is made with the net cash proceeds of an
Equity Offering, selection of the Securities or portions thereof for redemption
shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata
basis as is practicable (subject to the procedures of the Depository), unless
such method is otherwise prohibited.

         Section 3.3 Notice of Redemption. At least 30 days but not more than 60
days before a Redemption Date, the Issuers shall mail a notice of redemption by
first class mail, postage prepaid, to each Holder whose Securities are to be
redeemed at its registered address. At the


                                      -37-


<PAGE>   42


Issuers' request, the Trustee shall give the notice of redemption in the
Issuers' name and at the Issuers' expense. Each notice of redemption shall
identify the Securities to be redeemed and shall state:

                  (1)  the Redemption Date;

                  (2) the Redemption Price and the amount of accrued interest,
if any, to be paid;

                  (3)  the name and address of the Paying Agent;

                  (4) that Securities called for redemption must be surrendered
to the Paying Agent to collect the Redemption Price plus accrued interest, if
any;

                  (5) that, unless the Issuers defaults in making the redemption
payment, interest on Securities called for redemption ceases to accrue on and
after the Redemption Date, and the only remaining right of the Holders of such
Securities is to receive payment of the Redemption Price upon surrender to the
Paying Agent of the Securities redeemed;

                  (6) if any Security is being redeemed in part, the portion of
the principal amount of such Security to be redeemed and that, after the
Redemption Date, and upon surrender of such Security, a new Security or
Securities in aggregate principal amount equal to the unredeemed portion thereof
will be issued;

                  (7) if fewer than all the Securities are to be redeemed, the
identification of the particular Securities (or portion thereof) to be redeemed,
as well as the aggregate principal amount of Securities to be redeemed and the
aggregate principal amount of Securities to be outstanding after such partial
redemption; and

                  (8) the Section of this Indenture pursuant to which the
Securities are to be redeemed.

         The notice, if mailed in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security designated for redemption in whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

         Section 3.4 Effect of Notice of Redemption. Once notice of redemption
is mailed in accordance with Section 3.3, Securities called for redemption
become due and payable on the Redemption Date and at the Redemption Price plus
accrued and unpaid interest, if any. Upon surrender to the Trustee or Paying
Agent, such Securities called for redemption shall be paid at the Redemption
Price (which shall include accrued interest thereon to the Redemption Date), but
installments of interest, the maturity of which is on or prior to the Redemption
Date, shall be payable to Holders of record at the close of business on the
relevant Record Dates.

York time on the Redemption Date, the Issuers shall deposit with the Paying
Agent U.S. Legal Tender sufficient to pay the Redemption Price plus accrued
interest, if any, of all Securities to be redeemed on that date.

         If the Issuers comply with the preceding paragraph, then, unless the
Issuers default in the payment of such Redemption Price plus accrued interest,
if any, interest on the Securities to be redeemed will cease to accrue on and
after the applicable Redemption Date, whether or not such Securities are
presented for payment.

         Section 3.6 Securities Redeemed in Part. Upon surrender of a Security
that is to be redeemed in part only, the Trustee shall upon written instruction
from the Issuers authenticate for the Holder a new Security or Securities in a
principal amount equal to the unredeemed portion of the Security surrendered.

         Section 3.7 Optional Redemption. (a) Except as provided in Section
3.7(b), the Securities will not be redeemable at the option of the Issuers prior

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 such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued by this
Section 4.3 shall be determined by the Board of Directors of Parent whose

shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, Incur any Indebtedness (other than Permitted Indebtedness);
provided, that if no Default or Event of Default shall have occurred and be
continuing at the time or as a consequence of the Incurrence of any such
Indebtedness, NATG or any Subsidiary Guarantor may Incur Indebtedness
(including, without limitation, Acquired Indebtedness), if on the date of the
Incurrence of such Indebtedness, after giving effect to the Incurrence thereof,
the Consolidated Fixed Charge Coverage Ratio is greater than 2.0 to 1.0 during
the period commencing on the Issue Date and ending January 31, 2002, 2.25 to 1.0
during the period commencing February 1, 2002 and ending January 31, 2004, and

limited liability company existence and the corporate, limited liability
company, partnership or other existence of each of its Restricted Subsidiaries
(including the Corporate Issuer) in accordance with the respective
organizational documents of each such Restricted Subsidiary and the rights
(charter and statutory) and material franchises of NATG and each of its
Restricted Subsidiaries; provided, that NATG shall not be required to preserve
any such right, franchise or corporate existence with respect to any Subsidiary
of an Issuer if the Board of Directors of Parent shall determine that the loss
thereof is not, and will not be, adverse in any material respect to the Holders;
and provided, further, that notwithstanding anything to the contrary in this
Indenture, the Issuers shall ensure that at all times at least one of the
Issuers or any co-issuer of the Securities is a corporation organized under the
laws of the United States or any state thereof or the District of Columbia.

         Section 4.6 Payment of Taxes and Other Claims. (a) NATG will, and will
cause each of its Restricted Subsidiaries to, pay all material taxes,
assessments and other governmental charges imposed upon it or any of its
properties or assets or in respect of any of its income, businesses or
franchises before any penalty, fine or interest accrues thereon, and all claims
(including, without limitation, claims for labor, services, materials and
supplies) for sums that have become due and payable and that by law have or may
become a Lien upon any of its properties or assets, prior to the time when any
penalty, fine or interest shall be incurred with respect thereto; provided, that
no such charge or claim need be paid if being contested in good faith by
appropriate proceedings promptly instituted and diligently conducted and if such
reserve or other appropriate provision, if any, with respect to any liability
for taxes, as shall be required in conformity with GAAP shall have been made
therefor in the financial statements of NATG or any of its Restricted
Subsidiaries.

         (b) NATG will not, and will not permit any of its Restricted
Subsidiaries to, file or consent to the filing of any consolidated income tax
return with any Person (other than Parent and its Restricted Subsidiaries).

will cause its Restricted Subsidiaries to, maintain or cause to be maintained in
good repair, working order and condition, ordinary wear and tear excepted, all
material properties used or useful in the business of NATG and its Restricted
Subsidiaries and from time to time will make or cause to be made all appropriate
repairs, renewals and replacements thereof. NATG will maintain or cause to be
maintained, with financially sound and reputable insurers, insurance with
respect to its properties and business and the properties and businesses of its
Restricted Subsidiaries against loss or damage (including, without limitation,
business interruption insurance) of the kinds customarily carried or maintained
under similar circumstances by corporations of established reputation engaged in
similar businesses.

         Section 4.8 Compliance Certificate; Notice of Default. (a) Each Issuer
shall deliver to the Trustee, within 120 days after the close of each fiscal
year an Officers' Certificate stating that a review of the activities of such
Issuer has been made under the supervision of the signing Officers with a view
to determining whether it has kept, observed, performed and fulfilled its
obligations under this Indenture and further stating, as to each such Officer
signing such



                                      -43-



<PAGE>   48

certificate, that to the best of such Officer's knowledge, such Issuer during
such preceding fiscal year has kept, observed, performed and fulfilled each and
every such covenant and no Default or Event of Default occurred during such year
and at the date of such certificate there is no Default or Event of Default that
has occurred and is continuing or, if such signers do know of such Default or
Event of Default, the certificate shall describe its status with particularity.
The Officers' Certificate shall also notify the Trustee should the Issuers elect
to change the manner in which it fixes its fiscal year end.

         (b) So long as not contrary to the recommendations of the American
Institute of Certified Public Accountants, the annual financial statements
delivered pursuant to Section 4.10 shall be accompanied by a written report of
the Issuers' independent accountants (who shall be a firm of established
national reputation) that in conducting their audit of such financial statements
nothing has come to their attention that would lead them to believe that the
Issuers have violated any provisions of Article Four, Five or Six of this
Indenture insofar as they relate to accounting matters or, if any such violation
has occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

         (c) Each Issuer shall deliver to the Trustee, forthwith upon becoming
aware of any Default or Event of Default in the performance of any covenant,
agreement or condition contained in this Indenture, an Officers' Certificate
specifying the Default or Event of Default and describing its status with
particularity.

each of its Restricted Subsidiaries to comply, with all applicable statutes,
rules, regulations, orders and restrictions of the United States, all states and
municipalities thereof, and of any governmental department, commission, board,
regulatory authority, bureau, agency and instrumentality of the foregoing, in
respect of the conduct of their respective businesses and the ownership of their
respective properties, except for such noncompliances as would not in the
aggregate have a material adverse effect on the financial condition or results
of operations of NATG and its Restricted Subsidiaries taken as a whole.

         Section 4.10 Reports to Holders. (a) Whether or not required by the
rules and regulations of the SEC, so long as any Securities are outstanding,
Parent and the Issuers shall furnish the Holders of Securities:

                  (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 such 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 (or, if Parent shall cease to own more than a majority of
         the Voting Securities of NATG, of NATG and its consolidated
         subsidiaries) (showing in the case of Parent's financial statements, in
         reasonable detail, either on the face of the financial statements or in
         the footnotes thereto, the information required to be presented with

         SEC with respect thereto) and, with respect to the annual information
         only, a report thereon 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;

                  (2) 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
         such reports, in each case within two days after the time periods
         specified in the SEC's rules and regulations.

         (b) Following the consummation of the exchange offer contemplated by a
Registration Rights Agreement, whether or not required by the rules and
regulations of the SEC, Parent or NATG will file a copy of all such 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
such a filing) and make such information available to securities analysts and
prospective investors upon request. In addition, for so long as any Securities
remain outstanding, NATG shall furnish to the Holders and to securities analysts
and prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act. Parent and the
Issuers will also comply with the other provisions of TIA ss.314(a).

         Section 4.11 Waiver of Stay, Extension or Usury Laws. Each of the
Issuers and each Guarantor covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any
usury law or other law that would prohibit or forgive such Issuer or Guarantor
from paying all or any portion of the principal of and/or interest on the
Securities or the Guarantee of any such Guarantor as contemplated herein,
wherever enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture, and (to the extent that it may
lawfully do so) each hereby expressly waives all benefit or advantage of any
such law, and covenants that it will not hinder, delay or impede the execution
of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

         Section 4.12 Limitations on Transactions with Affiliates. (a) NATG
shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, enter into or permit to exist any transaction (including, without
limitation, the purchase, sale, lease or exchange of any property or the
rendering of any service) with or for the benefit of any Affiliate (each an
"Affiliate Transaction") other than (i) Affiliate Transactions permitted under
the following paragraph and (ii) Affiliate Transactions on terms that are no
less favorable to NATG or such Restricted Subsidiary, as the case may be, than
those that might reasonably have been obtained in a comparable transaction at
such time on an arm's-length basis from a Person that is not an Affiliate of
NATG or such Restricted Subsidiary. All Affiliate Transactions (and each series
of related Affiliate Transactions which 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
such Restricted Subsidiary, as the case may be, such approval to be



                                      -45-



<PAGE>   50

evidenced by a resolution stating that such Board of Directors has determined
that such transaction complies with the foregoing provisions. If NATG or any
such Restricted Subsidiary enters into an Affiliate Transaction (or a series of
related Affiliate Transactions related to a common plan) that involves an
aggregate fair market value of more than $10.0 million, NATG or such Restricted
Subsidiary, as the case may be, shall, prior to the consummation thereof, obtain
an opinion that the Affiliate Transaction complies with the requirements of this
covenant from an Independent Financial Advisor and file the same with the
Trustee.

         (b) The restrictions set forth in paragraph (a) shall not apply to: (i)
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; (ii) transactions exclusively between or among any
of NATG or any Restricted Subsidiaries of NATG; provided, that such transactions
are not otherwise prohibited by this Indenture; (iii) any agreement as in effect
as of the Issue Date or any amendment thereto or any transaction contemplated
thereby (including pursuant to any amendment thereto) in any replacement
agreement thereto so long as any such 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 Issue Date;
(iv) Restricted Payments permitted under Section 4.3; (v) any issuance of
securities or other payments, awards or grants in cash, securities or otherwise
pursuant to, or the funding of, 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; (vi) the payment of reasonable and
customary management, consulting and advisory fees and related out of pocket
expenses of WSP 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; (vii) 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; (viii) indemnification agreements provided for the benefit of

Parent; (ix) transactions effected as part of a Qualified Receivables
Transaction; and (x) the payment to Jack Reich for consulting services pursuant
to his consulting agreement with Parent and its Subsidiaries as in effect as of
the Issue Date or any amendment thereto or any transaction contemplated thereby
(including pursuant to any amendment thereto) in any replacement agreement
thereto so long as any such 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 Issue Date.

         Section 4.13 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: (a) pay dividends or make any other
distributions on or in respect of its Capital Stock; (b) make loans or advances
to pay any Indebtedness or other obligation owed to any Issuer or Subsidiary
Guarantor; or (c) transfer any of its property or assets to any Issuer or
Subsidiary Guarantor, except for such encumbrances or restrictions existing
under or by reason of: (1) applicable law, regulations or orders of any





                                      -46-



<PAGE>   51

governmental or judicial authority; (2) this Indenture, the Securities, the
Guarantees, or the Senior Secured Credit Agreement to the extent Incurred in

restriction or encumbrance contained in contracts for sale of assets permitted
by this Indenture in respect of the assets being sold pursuant to such contracts
pending the close of such sale, which encumbrance or restriction is not
applicable to any asset other than the asset being sold pursuant to such
contract; (6) Purchase Money Obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in clause
(c) above on the property so acquired; (7) restrictions of the nature described
in clause (c) above on the transfer of assets subject to any Lien permitted
under this Indenture imposed by the holder of such Lien; (8) 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 such acquisition (except
to the extent such Indebtedness or Capital Stock was incurred in connection with
or in contemplation of such 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, such Indebtedness was permitted by the terms
of this Indenture to be incurred; (9) 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

issued, assumed or incurred pursuant to an agreement referred to in clause (b)
or (d) above; provided, that the provisions relating to such encumbrance or
restriction contained in any such Indebtedness are 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 such encumbrance or restriction contained in agreements
referred to in such clause (b) or (d).

`         Section 4.14 Limitation on Liens. NATG shall not, and shall not permit
any of its Restricted Subsidiaries to, directly or indirectly, create, incur,
assume or permit to exist any Lien on or with respect to any property or asset
of any kind (including any document or instrument in respect of goods or

owned or hereafter acquired, or any income or profits therefrom, or 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 any such property, asset,
income or profits under the Uniform Commercial Code of any state or under any
similar recording or notice statute, unless, (i) in the case of Liens securing
Subordinated Indebtedness, the Securities and Guarantees are secured by a Lien
on such property, assets or proceeds that is senior in priority to such Liens
and (ii) in all other cases, the Securities and Guarantees are equally and
ratably secured. Notwithstanding the foregoing, this Section 4.14 shall not
prohibit or apply to (A) Liens securing the Senior Secured Credit Agreement; (B)

Securities at a purchase price equal to 101% of the principal amount thereof,
plus accrued and unpaid interest, if any, thereon to the Change of Control
Payment Date. The Change of Control Offer shall remain open for at least 20
Business Days and until the close of business on the Change of Control Payment
Date.

         (b) Prior to the mailing of the notice referred to below, but in any
event within 30 days following any Change of Control, each Issuer covenants to
(i) repay in full all Indebtedness under the Senior Secured Credit Agreement and

and all other such Senior Debt and to repay the Indebtedness owed to each lender
which has accepted such offer or (ii) obtain the requisite consents under the
Senior Secured Credit Agreement and all other Senior Debt to permit the
repurchase of the Securities as provided below. An Issuer shall first comply
with the covenant in the immediately preceding sentence before it shall be
required to repurchase Securities pursuant to the provisions described below. An
Issuer's failure to comply with the covenant described in the second preceding
sentence (and any failure to send the notice referred to in clause (c) below
because same is prohibited by the second preceding sentence) may (with notice
and lapse of time) constitute an Event of Default described in clause (c) of
Section 6.1 but shall not constitute an Event of Default described in clause (b)
of Section 6.1.

         (c) Within 30 days following the date upon which a Change of Control
occurs (the "Change of Control Date"), the Issuers shall 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 to the Holders shall
contain all instructions and materials necessary to enable such Holders to
tender Securities pursuant to the Change of Control Offer. Such notice shall
state:

                  (1) that the Change of Control Offer is being made pursuant to
         this Section 4.15 and that all Securities tendered and not withdrawn
         will be accepted for payment;

                  (2) the purchase price (including the amount of accrued
         interest) and the Change of Control Payment Date, which shall be a
         Business Day, that is not earlier than 30 days or later than 45 days
         from the date such notice is mailed;

                  (3) that any Security not tendered will continue to accrue
         interest;

                  (4) that, unless the Issuers default in making payment
         therefor, any Security accepted for payment pursuant to the Change of
         Control Offer shall cease to accrue interest after the Change of
         Control Payment Date;

         on the third Business Day prior to the Change of Control Payment Date;

                  (6) that Holders will be entitled to withdraw their election
         if the Paying Agent receives, not later than the second Business Day
         prior to the Change of Control Payment Date, a telegram, telex,
         facsimile transmission or letter setting forth the name of the Holder,
         the principal amount of the Securities the Holder delivered for

         of Control.

         (d) On or before the Change of Control Payment Date, the Issuers shall
(i) accept for payment Securities or portions thereof tendered pursuant to the
Change of Control Offer, (ii) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the purchase price plus accrued interest, if any, of all

together with an Officers' Certificate stating the Securities or portions
thereof being purchased by the Issuers. The Paying Agent shall promptly mail to
the Holders of Securities so accepted payment in an amount equal to the purchase
price plus accrued interest, if any, and upon written order of the Issuers the
Trustee shall promptly authenticate and mail to such Holders new Securities
equal in principal amount to any unpurchased portion of the Securities

Securities pursuant to a Change of Control Offer shall be returned by the
Trustee to the Issuers.

         (f) The Issuers intend to comply with the requirements of Rule 14e-1
under the Exchange Act to the extent such laws and regulations are applicable in
connection with the repurchase of Securities pursuant to a Change of Control
Offer. To the extent the Issuers comply with the provisions of any such
securities laws or regulations, the Issuers will not be deemed to have breached
their obligations under the provisions of this Section 4.15.

         Section 4.16 Limitation on Asset Sales. (a) NATG shall not, and shall
not permit any of its Restricted Subsidiaries to, consummate an Asset Sale,
unless (i) NATG or the applicable Restricted Subsidiary, as the case may be,
receives consideration at the time of such 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); (ii)
at least 75% of the consideration received by the Issuers or the Restricted
Subsidiary, as the case may be, from such Asset Sale is received at the time of
the disposition and consists of one of the following: (a) cash or Cash
Equivalents; (b) any liabilities (as shown on NATG's or such Restricted
Subsidiary's most recent balance sheet) of NATG or any such Restricted
Subsidiary (other than liabilities that are by their terms subordinated to the
Securities) that are assumed by the transferee of any such assets, (c)


                                      -49-

<PAGE>   54

any securities, notes or other obligations received by NATG or any such
Subsidiary from such transferee that are converted by NATG or any such
Subsidiary into cash within 180 days after such Asset Sale (to the extent of the
cash received); and (d) any combination of the foregoing; (iii) upon the
consummation of an Asset Sale, NATG shall apply, or cause such Restricted
Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within
365 days of receipt thereof either (A) to prepay any Senior Debt or Guarantor
Senior Debt and, in the case of any Senior Debt or Guarantor Senior Debt under
any revolving credit facility, effect a permanent reduction in the availability
under such revolving credit facility; provided, that no such permanent reduction
in availability need 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 and/or
(B) to invest in or to acquire other properties and assets that replace the
properties and assets that were the subject of such Asset Sale or in properties
and assets that will be used or useful in a Permitted Business ("Replacement
Assets") and/or (C) to acquire all or substantially all of the assets of, or all
of the voting stock of, another Person engaged in a Permitted Business;
provided, that if voting stock is acquired, such Person becomes a Subsidiary
Guarantor; provided, that NATG may not sell or otherwise dispose of any Capital
Stock of the Corporate Issuer except in compliance with Section 5.1. Pending the
final application of any Net Cash Proceeds, NATG or such Restricted Subsidiary
may temporarily reduce revolving credit borrowings or otherwise invest such Net
Cash Proceeds in any manner that is not otherwise prohibited by this Indenture.
On the 366th day after an Asset Sale or such earlier date, if any, as the senior
management or Board of Directors, as the case may be, of NATG or such Restricted
Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset
Sale as set forth in clause (iii) of the preceding paragraph (each, a "Net
Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which
has not been applied on or before such Net Proceeds Offer Trigger Date as
permitted in clause (iii) of the next preceding sentence (each a "Net Proceeds
Offer Amount") shall be applied by NATG or such Restricted Subsidiary to make an
offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer
Payment 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 Securities equal to the Net Proceeds Offer Amount at a price
equal to 100% of the principal amount of the Securities to be purchased, plus
accrued and unpaid interest thereon, if any, to the date of purchase; provided,
that if at any time any non-cash consideration received by NATG or any such
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 such non-cash consideration), then such conversion
or disposition shall be deemed to constitute an Asset Sale hereunder and the Net
Cash Proceeds thereof 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
required pursuant to this paragraph).

         (b) 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
Section 5.1. hereof, 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

                                      -50-

<PAGE>   55

covenant, and shall comply with the provisions of this covenant with respect to
such deemed sale as if it were an Asset Sale. In addition, the fair market value
of such properties and assets of NATG or such Subsidiaries deemed to be sold
pursuant to this paragraph less the fair market value of all liabilities of such
Person related to such property and assets not transferred shall be deemed to be
Net Cash Proceeds for purposes of this covenant.

         (c) Notwithstanding the foregoing provisions of this covenant, NATG and
its Restricted Subsidiaries will be permitted to consummate an Asset Sale
without complying with such clauses to the extent that: (1) at least 75% of the
consideration for such Asset Sale constitutes Replacement Assets; and (2) such
Asset Sale is for fair market value as determined in good faith by the Board of
Directors of Parent; provided, that 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 (c)
shall constitute Net Cash Proceeds subject to the provisions the foregoing
provisions of this covenant.

         (d) 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 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 such longer period as may
be required by law. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Securities pursuant to the Net
Proceeds Offer and shall comply with the procedures set forth in this Indenture.
To the extent that the aggregate amount of Securities 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 this Indenture, and any such remaining Net
Cash Proceeds shall thereafter be deemed not to constitute Net Cash Proceeds.

         (e) NATG and its Restricted Subsidiaries intend to comply with the
requirements of Rule 14e-1 under the Exchange Act to the extent such laws and
regulations are applicable in connection with the repurchase of Securities
pursuant to 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 thereof.

         Section 4.17 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 Securities 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 such Indebtedness) subordinated in right of payment to any other
Indebtedness of such Person unless such Indebtedness (i) is Incurred by an
Issuer or Subsidiary Guarantor and (ii) is by its terms (or by the terms of any
agreement governing such Indebtedness) made expressly subordinate to the
obligations of such Issuer or Subsidiary Guarantor under this Indenture, the
Securities (in the case of an Issuer) and the Guarantees (in the case of a
Subsidiary

                                      -51-

<PAGE>   56

Guarantor) to the same extent and in the same manner as such obligations are
subordinated to Senior Debt or Guarantor Senior Debt, as applicable.

         Section 4.18 Additional Subsidiary Guarantees. (a) NATG will cause any
Subsidiary of NATG that after the Issue Date 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 such a guarantor (i) execute and deliver to
the Trustee a supplemental indenture in form reasonably satisfactory to the
Trustee pursuant to which such Subsidiary shall unconditionally guarantee all of
the Issuers' obligations under the Securities and this Indenture on the terms
set forth in this Indenture and (ii) deliver to the Trustee an Opinion of
Counsel that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary and constitutes a legal, valid, binding and
enforceable obligation of such Subsidiary. Thereafter, such Subsidiary shall be
a Guarantor for all purposes of this Indenture.

         (b) 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 (i) execute and deliver to the Trustee a supplemental
indenture in form reasonably satisfactory to the Trustee pursuant to which such
Subsidiary shall unconditionally guarantee all of the Issuers' obligations under
the Securities and this Indenture on the terms set forth in this Indenture and
(ii) deliver to the Trustee an Opinion of Counsel that such supplemental
indenture has been duly authorized, executed and delivered by such Subsidiary
and constitutes a legal, valid, binding and enforceable obligation of such
Subsidiary. Thereafter, such Subsidiary shall be a Guarantor for all purposes of
this Indenture.

         Section 4.19 Conduct of Business. (a) NATG shall not, and shall not
permit any of its Restricted Subsidiaries to, engage in any business other than
Permitted Businesses.

         (b) The Corporate Issuer shall engage in no business other than the
issuance of the Securities. Notwithstanding the foregoing, the Corporate Issuer
may engage in those activities that are incidental to (i) the maintenance of is
corporate existence in compliance with applicable law, (ii) legal, tax and
accounting matters in connection with any of the foregoing activities and (iii)
entering into, and performing its obligations under, the Documents to which it
is a party.

         Section 4.20 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 Section 4.3 and Section 5.1, NATG will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly sell,
assign, pledge or otherwise encumber or dispose of any shares of Capital Stock
or other equity securities of any Restricted Subsidiary of NATG, except (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.

         Section 4.21 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 Securities for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Securities unless such consideration is offered to be


                                      -52-

paid and is paid to all Holders of the Securities that consent, waive or agree
to amend in the time frame set forth in the solicitation documents relating to
such consent, waiver or agreement.

take all actions required to maintain NATG's status and the status of NATG's
Restricted Subsidiaries as separate legal entities from Parent, including,
without limitation; (i) not holding NATG or its Restricted Subsidiaries out to
third parties as other than entities with assets and liabilities distinct from
Parent and Parent's other subsidiaries; (ii) not holding Parent out to be
responsible for the debts of NATG or NATG's Restricted Subsidiaries or, other

                              DEFAULT AND REMEDIES

receive written notice specifying the default (and demanding that such default

stated maturity of any such Indebtedness (which acceleration is not rescinded,
annulled or otherwise cured within 20 days of receipt by NATG or such Restricted
Subsidiary of notice of any such acceleration) if the aggregate principal amount
of such Indebtedness, together with the principal amount of any other such
Indebtedness in default for failure to pay principal at final maturity or which
has been accelerated (in each case with respect to which the 20-day period
described above has elapsed), aggregates $10.0 million or more at any time;

         (e) 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 such judgments remain undischarged, unpaid or unstayed for a
period of 60 days after such judgment or judgments become final and
non-appealable;

         (f) Parent, an Issuer, or any of their respective Significant
Subsidiaries (i) commences a voluntary case or proceeding under any Bankruptcy
Law with respect to itself, (ii) consents to the entry of a judgment, decree or
order for relief against it in an involuntary case or proceeding under any
Bankruptcy Law, (iii) consents to the appointment of a custodian of it or for

order the winding-up or liquidation of its affairs; and such judgment, decree or
order shall remain unstayed and in effect for a period of 60 consecutive days;
or

         (h) (i) any Guarantee or any provision thereof shall cease to be in
full force or effect (other than in accordance with its express terms), or (ii)
Parent or any other Guarantor or any Person acting by or on behalf of such
Guarantor shall deny or disaffirm such Guarantor's obligations under its
Guarantee, or (iii) Parent or any other Guarantor shall default in the due
performance or observance of any term, covenant or agreement on its part to be
performed or observed, after giving effect to any applicable grace periods,
pursuant to its Guarantee.

         Section 6.2 Acceleration. If an Event of Default (other than an Event
of Default specified in either clause (f) or (g) of Section 6.1 above with
respect to an Issuer) shall occur and be continuing, the Trustee or the Holders
of at least 25% in principal amount of outstanding

                                      -56-

<PAGE>   61

Securities may declare the principal of and accrued interest on all the
Securities to be due and payable by notice in writing to the Issuers (and the
Trustee if given by the Holders) specifying the respective Event of Default and
that it is a "notice of acceleration" (the "Acceleration Notice"), and the same
(i) shall become immediately due and payable or (ii) 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 such Acceleration
Notice but only if such Event of Default is then continuing. If an Event of
Default specified in either clause (f) or (g) of Section 6.1 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
Securities shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.

         At any time after a declaration of acceleration with respect to the
Securities as described in the preceding paragraph, the Holders of a majority in
principal amount of the Securities may rescind and cancel such declaration and
its consequences (i) if the rescission would not conflict with any judgment or
decree, (ii) 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, (iii) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid,
(iv) if the Issuers have paid the Trustee its reasonable compensation and
reimbursed the Trustee for its expenses, disbursements and advances and (v) in
the event of the cure or waiver of an Event of Default of the type described in
either clause (f) or (g) of Section 6.1, the Trustee shall have received an
Officers' Certificate from each Issuer and an Opinion of Counsel that such Event
of Default has been cured or waived. No such rescission shall affect any
subsequent Default or impair any right consequent thereto.

         Section 6.3 Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or
in equity to collect the payment of principal of or interest on the Securities
or to enforce the performance of any provision of the Securities or this
Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

         Section 6.4 Waiver of Past Defaults. Subject to Sections 2.9, 6.7 and
9.2, the Holders of not less than a majority in principal amount of the
outstanding Securities by notice to the Trustee may waive an existing Default or
Event of Default and its consequences, except a Default in the payment of
principal of or interest on any Security as specified in clauses (a) and (b) of
Section 6.1. Each Issuer shall deliver to the Trustee an Officers' Certificate
stating that the requisite


                                      -57-

<PAGE>   62

percentage of Holders have consented to such waiver and attaching copies of such
consents. When a Default or Event of Default is waived, it is cured and ceases.

         Section 6.5 Control by Majority. The Holders of not less than a
majority in principal amount of the outstanding Securities may direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on it. Subject to Section
7.1, however, the Trustee may refuse to follow any direction that conflicts with
any law or this Indenture, that the Trustee determines may be unduly prejudicial
to the rights of another Securityholder, or that may involve the Trustee in
personal liability; provided, that the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction.

         In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against any loss or expense caused by
taking such action or following such direction.

         Section 6.6 Limitation on Suits. A Securityholder may not pursue any
remedy with respect to this Indenture or the Securities unless:

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

         (2) the Holder or Holders of at least 25% in principal amount of the
outstanding Securities make a written request to the Trustee to pursue the
remedy;

         (3) such Holder or Holders offer and, if requested, provide to the
Trustee indemnity satisfactory to the Trustee against any loss, liability or
expense;

         (4) the Trustee does not comply with the request within 45 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

         (5) during such 45-day period the Holder or Holders of a majority in
principal amount of the outstanding Securities do not give the Trustee a
direction which, in the opinion of the Trustee, is inconsistent with the
request.

         A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over such other
Securityholder.

         Section 6.7 Rights of Holders To Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal of and interest on a Security, on or after the respective due dates
expressed in such Security, or to bring suit for the enforcement of any such
payment on or after such respective dates, shall not be impaired or affected
without the consent of the Holder.

         Section 6.8 Collection Suit by Trustee. If an Event of Default in
payment of principal or interest specified in clause (a) or (b) of Section 6.1
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Issuers or any


                                      -58-

<PAGE>   63

other obligor on the Securities or the Guarantees for the whole amount of
principal and accrued interest and fees remaining unpaid, together with interest
on overdue principal and, to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate per annum
borne by the Securities and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

         Section 6.9 Trustee May File Proofs of Claim. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel) and the Securityholders allowed in any judicial
proceedings relating to any Issuer or Guarantor, their respective creditors or
property, and shall be entitled and empowered to participate as a member, voting
or otherwise, of any official committee of creditors appointed in such matter
and to collect and receive any monies or other property payable or deliverable
on any such claims and to distribute the same, and any Custodian in any such
judicial proceedings is hereby authorized by each Securityholder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Securityholders, to pay to the Trustee
any amount due to it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agent and counsel, and any other amounts due
the Trustee under Section 7.7. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding.

         Section 6.10 Priorities. If the Trustee collects any money or property
pursuant to this Article Six, it shall pay out the money or property in the
following order:

         First:  to the Trustee for amounts due under Section 7.7;

         Second:  to Holders for interest  accrued on the Securities,  ratably,
without preference or priority of ny kind, according to the amounts due and
payable on the Securities for interest;

         Third: to Holders for principal amounts due and unpaid on the
Securities, ratably, without preference or priority of any kind, according to
the amounts due and payable on the Securities for principal; and

         Fourth: to the Issuers or, if applicable, the Guarantors, as their
respective interests may appear.

         The Trustee, upon prior notice to the Issuers, may fix a record date
and payment date for any payment to Securityholders pursuant to this Section
6.10.

         Section 6.11 Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an


                                      -59-

undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7, or a suit
by a Holder or Holders of more than 10% in principal amount of the outstanding
Securities.

                                     TRUSTEE

         Section 7.1 Duties of Trustee. (a) If an Event of Default has occurred
and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent person would exercise or use under the circumstances
in the conduct of his or her own affairs.

         (b)  Except during the continuance of an Event of Default:

                  (1) The Trustee need perform only those duties as are
         specifically set forth herein or in the TIA and no duties, covenants,
         responsibilities or obligations shall be implied in this Indenture
         against the Trustee.

                  (2) In the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates
         (including Officers' Certificates) or opinions (including Opinions of
         Counsel) furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture, but shall not be obligated to verify the contents
         thereof.

         (c) Notwithstanding anything to the contrary herein, the Trustee may
not be relieved from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

                  (1) This paragraph (c) does not limit the effect of paragraph
         (b) of this Section 7.1.

                  (2) The Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts.

                  (3) The Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.5.

<PAGE>   65


         (d) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or take any action at the request or direction of Holders
if it shall have reasonable grounds for believing that repayment of such funds

Trustee is subject to this Section 7.1.

         (f) The Trustee shall not be liable for interest on any money received

the part of the Trustee, the Trustee shall not be responsible for the

         (a) The Trustee may rely on any document believed by it to be genuine
and to have been signed or presented by the proper Person. The Trustee need not
investigate any fact or matter stated in the document.

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate and an Opinion of Counsel, which shall to the extent
relevant, conform to the provisions of Section 13.5. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such certificate or opinion.

         (c) The Trustee may act through its attorneys and agents and shall not
be responsible for the misconduct or negligence of any agent (other than an
agent who is an employee of the Trustee) appointed with due care.

         (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith which it reasonably believes to be authorized or within its
rights or powers.

         (e) The Trustee may consult with counsel and the advice or opinion of
such counsel as to matters of law shall be full and complete authorization and
protection from liability in respect of any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

         (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders pursuant to the provisions of this Indenture,

indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.

facts or matters stated in any resolution, certificate (including any Officers'
Certificate), statement, instrument, opinion (including any Opinion of Counsel),
notice, request, direction, consent, order, bond, debenture, or other paper or
document, but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit and, if the Trustee

entitled, upon reasonable notice to the Issuers, to examine the books, records,
and premises of the Issuers, personally or by agent or attorney.

         (h) The Trustee shall not be required to give any bond or surety in
respect of the performance of its powers and duties hereunder.

         (i) The permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as duties.

         Section 7.3 Individual Rights of Trustee. The Trustee in its individual
or any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Issuers, their respective Subsidiaries, and their
respective Affiliates with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

         Section 7.4 Trustee's Disclaimer. The Trustee shall not be responsible
for and makes no representation as to the validity or adequacy of this Indenture
or the Securities, it shall not be accountable for the Issuers' use of the
proceeds from the issuance of the Securities, and it shall not be responsible
for any statement of the Issuers or the Guarantors in this Indenture or any
document issued in connection with the sale of Securities or any statement in
the Securities other than the Trustee's certificate of authentication. The
Trustee makes no representations with respect to the effectiveness or adequacy
of this Indenture.

         Section 7.5 Notice of Default. If a Default or an Event of Default
occurs and is continuing and the Trustee receives actual notice of such Default
or Event of Default, the Trustee shall mail to each Securityholder notice of the
uncured Default or Event of Default within 60 days after such Default or Event
of Default occurs. Except in the case of a Default or an Event of Default in
payment of principal of, or interest on, any Security, including an accelerated
payment and the failure to make payment on the Change of Control Payment Date
pursuant to a Change of Control Offer or the Net Proceeds Offer Payment Date
pursuant to a Net Proceeds Offer, the Trustee may withhold the notice if and so
long as the Board of Directors, the executive committee, or a trust committee of
directors and/or Responsible Officers, of the Trustee in good faith determines
that withholding the notice is in the interest of the Securityholders.

         Section 7.6 Reports by Trustee to Holders. Within 60 days after each
May 15, beginning with the first May 15 following the date of this Indenture,
the Trustee shall, to the extent that any of the events described in TIA ss.
313(a) occurred within the previous twelve months, but not otherwise, mail to
each Securityholder a brief report dated as of such date that complies with TIA
ss. 313(a). The Trustee also shall comply with TIA ss.ss. 313(b), 313(c) and
313(d).

                                      -62-

<PAGE>   67

         A copy of each report at the time of its mailing to Securityholders
shall be mailed to the Issuers and filed with the Commission and each securities
exchange, if any, on which the Securities are then listed.

         The Issuers shall notify the Trustee if the Securities become listed on
any securities exchange or of any delisting thereof and the Trustee shall comply
with TIA ss. 313(d).

         Section 7.7 Compensation and Indemnity. The Issuers shall pay to the
Trustee from time to time reasonable compensation for its services hereunder.
The Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Issuers shall reimburse the Trustee upon
request for all reasonable disbursements, expenses and advances (including
reasonable fees and expenses of counsel) incurred or made by it in addition to
the compensation for its services, except any such disbursements, expenses and
advances as may be attributable to the Trustee's negligence, bad faith or
willful misconduct. Such expenses shall include the reasonable fees and expenses
of the Trustee's agents and counsel.

         The Issuers shall indemnify the Trustee and its agents, employees,
officers, stockholders and directors for, and hold them harmless against, any
claim (whether asserted by the Issuers or any other Person), loss, liability or
expense incurred by them except for such actions to the extent caused by any
negligence, bad faith or willful misconduct on their part, arising out of or in
connection with the acceptance or administration of this trust including the
costs and expenses of enforcing this Indenture against the Issuers (including
this Section 7.7), including the reasonable costs and expenses of defending
themselves against or investigating any claim or liability in connection with
the exercise or performance of any of the Trustee's rights, powers or duties
hereunder. The Trustee shall notify the Issuers promptly of any claim asserted
against the Trustee or any of its agents, employees, officers, stockholders and
directors for which it may seek indemnity. The Issuers may, subject to the
approval of the Trustee, defend the claim and the Trustee shall cooperate in the
defense. The Trustee and its agents, employees, officers, stockholders and
directors subject to the claim may have separate counsel and the Issuers shall
pay the reasonable fees and expenses of such counsel; provided, that the Issuers
will not be required to pay such fees and expenses if, subject to the approval
of the Trustee, it assumes the Trustee's defense and there is no conflict of
interest between the Issuers and the Trustee and its agents, employees,
officers, stockholders and directors subject to the claim in connection with
such defense as reasonably determined by the Trustee. The Issuers need not pay
for any settlement made without their written consent, which consent will not be
unreasonably withheld or delayed. The Issuers need not reimburse any expense or
indemnify against any loss or liability to the extent incurred by the Trustee
through its negligence, bad faith or willful misconduct.

         To secure the Issuers' payment obligations in this Section 7.7, the
Trustee shall have a senior claim prior to the Securities against all money or
property held or collected by the Trustee, in its capacity as Trustee, except
assets or money held in trust to pay principal of or interest on particular
Securities.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in clause (f) or (g) of Section 6.1 occurs, such expenses and
the compensation for such services shall be paid to the extent allowed under any
Bankruptcy Law.

         Notwithstanding any other provision in this Indenture, the foregoing
provisions of this Section 7.7 shall survive the satisfaction and discharge of
this Indenture or the appointment of a successor Trustee.

         Section 7.8 Replacement of Trustee. The Trustee may resign at any time
by so notifying the Issuers in writing. The Holders of a majority in principal
amount of the outstanding Securities may remove the Trustee by so notifying the
Issuers and the Trustee and may appoint a successor Trustee. The Issuers may
remove the Trustee if:

         (1)  the Trustee fails to comply with Section 7.10;

         (2)  the Trustee is adjudged a bankrupt or an insolvent;

         (3) a receiver or other public officer takes charge of the Trustee or
             its property; or

         (4) the Trustee becomes incapable of acting as trustee hereunder.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Issuers shall notify each Holder of such
event and shall promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of
the Securities may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuers.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Immediately after that,
the retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.7, all property held by it as Trustee to the
successor Trustee, subject to the Lien provided in Section 7.7, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Securityholder.

         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuers or the
Holders of at least 10% in principal amount of the outstanding Securities may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

         Notwithstanding replacement of the Trustee pursuant to this Section
7.8, the Issuers' obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee.

         Section 7.9 Successor Trustee by Merger, Etc. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation, the resulting,
surviving or transferee corporation without any further act shall, if such
resulting, surviving or transferee corporation is otherwise eligible hereunder,
be the successor Trustee, provided that such corporation shall be otherwise
qualified and eligible under this Article Seven.

         Section 7.10 Eligibility; Disqualification. This Indenture shall always
have a Trustee who satisfies the requirement of TIA ss.ss. 310(a)(1), 310(a)(2)
and 310(a)(5). The Trustee shall have a combined capital and surplus of at least
$50.0 million as set forth in its most recent published annual report of
condition. In addition, if the Trustee is a corporation included in a bank
holding company system, the Trustee, independently of the bank holding company,
shall meet the capital requirements of TIA ss. 310(a)(2). The Trustee shall
comply with TIA ss. 310(b); provided, that there shall be excluded from the
operation of TIA ss. 310(b)(1) any indenture or indentures under which other
securities, or certificates of interest or participation in other securities, of
the Issuers are outstanding, if the requirements for such exclusion set forth in
TIA ss. 310(b)(1) are met. The provisions of TIA ss. 310 shall apply to the
Issuers and any other obligor of the Securities.

         Section 7.11 Preferential Collection of Claims Against Company. The
Trustee, in its capacity as Trustee hereunder shall comply with TIA ss. 311(a),
excluding any creditor relationship listed in TIA ss. 311(b). A Trustee who has
resigned or been removed shall be subject to TIA ss. 311(a) to the extent
indicated.

                                  ARTICLE EIGHT

                       DISCHARGE OF INDENTURE; DEFEASANCE

         Section 8.1 Termination of the Issuers' Obligations. The Issuers may

Section 8.1, if all Securities previously authenticated and delivered (other
than destroyed, lost or stolen Securities which have been replaced or paid or
Securities for whose payment U.S. Legal Tender has theretofore been deposited
with the Trustee or the Paying Agent in trust or segregated and held in trust by
the Issuers and thereafter repaid to the Issuers, as provided in Section 8.5)
have been delivered to the Trustee for cancellation and the Issuers have paid
all sums payable by it hereunder, or if:

         (a) either (i) pursuant to Article Three, the Issuers shall have given
notice to the Trustee, and mailed a notice of redemption to each Holder, of the
redemption of all of the Securities in accordance with the provisions hereof or

         (b) the Issuers shall have irrevocably deposited or caused to be

consideration of reinvestment of such interest, to pay principal of, premium, if
any, and interest on the outstanding Securities to maturity or redemption;
provided, that the Trustee shall have been irrevocably instructed to apply such
U.S. Legal Tender to the payment of said principal, premium, if any, and
interest with respect to the Securities and provided, further, that from and
after the time of deposit, the money deposited shall not be subject to the
rights of holders of Senior Debt or Guarantor Senior Debt pursuant to the
provisions of Article Ten or Twelve, as the case may be;

         (c) no Default or Event of Default with respect to this Indenture or
the Securities shall have occurred and be continuing on the date of such deposit
or shall occur as a result of such deposit and such deposit will not result in a
breach or violation of, or constitute a default under, this Indenture, the
Senior Secured Credit Agreement, any other material agreement or instrument to
which Parent or any of its Subsidiaries is a party or by which it is bound;

         (d) the Issuers shall have paid all other sums payable by them
hereunder; and

         (e) each Issuer shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent providing for or relating to the termination of such Issuers'
obligations in respect of the Securities and this Indenture have been complied
with. Each such Opinion of Counsel shall also state that such satisfaction and
discharge does not result in a default under the Senior Credit Agreement or any
other material agreement or instrument then known to such counsel that binds or
affects such Issuer.

         Subject to the next sentence and notwithstanding the foregoing
paragraph, the Issuers' obligations in Sections 2.5, 2.6, 2.7, 2.8, 4.1, 4.2,
7.7, 8.5 and 8.6 shall survive until the Securities are no longer outstanding
pursuant to the last paragraph of Section 2.8. After the Securities are no
longer outstanding, the Issuers' obligations in Sections 7.7, 8.5 and 8.6 shall
survive.

         After such delivery or irrevocable deposit, the Trustee upon request
shall acknowledge in writing the discharge of the Issuers' obligations under the
Securities and this Indenture except for those surviving obligations specified
above.

         Section 8.2 Legal Defeasance and Covenant Defeasance. (a) The Issuers
may, at their option by Board Resolution of the Board of Directors of each
Issuer, at any time, elect to have either paragraph (b) or (c) below be applied

Section 8.3.

         (b) Upon the Issuers' exercise under paragraph (a) hereof of the option

of the conditions set forth in Section 8.3, be deemed to have been discharged
from their obligations with respect to all outstanding Securities on the date
the conditions set forth below are satisfied (hereinafter, "Legal Defeasance").
For this purpose, Legal Defeasance means that the Issuers shall be deemed to
have paid and discharged the entire Indebtedness represented by the outstanding
Securities, which shall thereafter be deemed to be "outstanding" only for the
purposes of Section 8.4 and the other Sections of this Indenture referred to in
clauses (i) and (ii) below, and to have satisfied all

                                      -66-

Trustee, on demand of and at the expense of the Issuers, shall execute proper
instruments prepared by the Issuers acknowledging the same), and Holders of the
Securities and any amounts deposited under Section 8.3 shall cease to be subject

under Article Two and Section 4.2 hereof, (iii) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and the Issuers' obligations in
connection therewith and (iv) this Article Eight. Subject to compliance with
this Article Eight, the Issuers may exercise their option under this paragraph
(b) notwithstanding the prior exercise of its option under paragraph (c) hereof.

         (c) Upon the Issuers' exercise under paragraph (a) hereof of the option
applicable to this paragraph (c), the Issuers shall, subject to the satisfaction
of the conditions set forth in Section 8.3 hereof, be released from their
obligations under the covenants contained in Sections 4.3, 4.4 and Sections 4.12
through 4.22 and Article Five hereof with respect to the outstanding Securities
on and after the date the conditions set forth below are satisfied (hereinafter,
"Covenant Defeasance"), and the Securities shall thereafter be deemed not
"outstanding" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Securities shall not be deemed
outstanding for accounting purposes) and Holders of the Securities and any
amounts deposited under Section 8.3 hereof shall cease to be subject to any
obligations to, or the rights of, any holder of Senior Debt under Article Ten or
otherwise. For this purpose, such Covenant Defeasance means that, with respect
to the outstanding Securities, the Issuers may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Section 6.1(c) hereof, but, except as specified above, the remainder of this
Indenture and such Securities shall be unaffected thereby. In addition, upon the
Issuers' exercise under paragraph (a) hereof of the option applicable to this
paragraph (c), subject to the satisfaction of the conditions set forth in
Section 8.3 hereof, Sections 6.1(c), 6.1(d) and 6.1(e) shall not constitute
Events of Default.

         Section 8.3 Conditions to Legal Defeasance or Covenant Defeasance. The
following shall be the conditions to the application of either Section 8.2(b) or
8.2(c) hereof to the outstanding Securities:

         In order to exercise either Legal Defeasance or Covenant Defeasance:

                                      -67-

<PAGE>   72

         (a) the Issuers must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders, U.S. Legal Tender or U.S. Government Obligations
or a combination thereof which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms, will provide, not
later than one day before the due date of any payment on the Securities, U.S.
Legal Tender in such amounts 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 Securities on the stated date
for payment thereof or on the applicable Redemption Date, as the case may be;

         (b) in the case of a 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 this Indenture, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such Opinion of
Counsel shall confirm that, the Holders will not recognize income, gain or loss
for federal income tax purposes as a result of such 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 such Legal Defeasance had not
occurred;

         (c) in the case of a 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 of the Securities will not
recognize income, gain or loss for federal income tax purposes as a result of
such 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
such Covenant Defeasance had not occurred;

         (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the incurrence of Indebtedness all or a portion of the proceeds
of which will be used to defease the Securities pursuant to this Article Eight
concurrently with such incurrence and the grant of any Lien securing such
incurrence) or insofar as Sections 6.1(f) and 6.1(g) hereof are concerned, at
any time in the period ending on the 91st day after the date of such deposit;

         (e) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under this Indenture (other than
a Default or Event of Default resulting from the incurrence of Indebtedness all
or a portion of the proceeds of which will be used to defease the Securities
pursuant to this Article Eight concurrently with such incurrence and the grant
of any Lien securing such incurrence), the Senior Secured Credit Agreement 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;

         (f) 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;

                                      -68-

<PAGE>   73

         (g) each Issuer shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with;

         (h) each Issuer shall have delivered to the Trustee an Opinion of
Counsel to the effect that (i) the trust funds will not be subject to any rights
of any holders of Senior Debt or Guarantor Senior Debt, including, without
limitation, those arising under this Indenture, and (ii) assuming no intervening
bankruptcy or insolvency of an Issuer between the date of deposit and the 91st
day following the deposit and that no Holder is an insider of an Issuer, after
the 91st day following the deposit, the trust funds will not be subject to the
effect of any applicable Bankruptcy Law; and

         (i) if at the time, Securities are listed on a national securities
exchange, each Issuer shall have delivered to the Trustee and Opinion of Counsel
to the effect that the Securities will not be delisted as a result of such
deposit, defeasance and discharge.

         Notwithstanding the foregoing, the Opinion of Counsel required by
clause (b) above of this Section 8.3 with respect to a Legal Defeasance need not
be delivered if all Securities not theretofore delivered to the Trustee for
cancellation (i) have become due and payable or (ii) 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.

         Section 8.4 Application of Trust Money. The Trustee or Paying Agent
shall hold in trust U.S. Legal Tender or U.S. Government Obligations deposited
with it pursuant to this Article Eight, and shall apply the deposited U.S. Legal
Tender and the money from U.S. Government Obligations in accordance with this
Indenture to the payment of principal of and interest on the Securities. The
Trustee shall be under no obligation to invest said U.S. Legal Tender or U.S.
Government Obligations except as it may agree with the Issuers.

         The Issuers shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Legal Tender or U.S.
Government Obligations deposited pursuant to Section 8.3 hereof or the principal
and interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities.

         Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuers from time to time upon the Issuers'
request any U.S. Legal Tender or U.S. Government Obligations held by it as
provided in Section 8.3 hereof the amount of which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, is in excess of the
amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance.

         Section 8.5 Repayment to the Issuers. Subject to this Article Eight,
the Trustee and the Paying Agent shall promptly pay to the Issuers upon request
any excess U.S. Legal Tender or U.S. Government Obligations held by them at any
time and thereupon shall be relieved from all

                                      -69-
<PAGE>   74

liability with respect to such money. The Trustee and the Paying Agent shall pay
to the Issuers upon request any money held by them for the payment of principal
or interest that remains unclaimed for two years; provided, that the Trustee or
such Paying Agent, before being required to make any payment, may at the expense
of the Issuers cause to be published once in a newspaper of general circulation
in The City of New York and mail to each Holder entitled to such money notice
that such money remains unclaimed and that after a date specified therein which
shall be at least 30 days from the date of such publication and mailing any
unclaimed balance of such money then remaining will be repaid to the Issuers.
After payment to the Issuers, Holders entitled to such money must look to the
Issuers for payment as general creditors unless an applicable law designates
another Person.

         Section 8.6 Reinstatement. If the Trustee or Paying Agent is unable to
apply any U.S. Legal Tender or U.S. Government Obligations in accordance with
this Article Eight by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Issuers' obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article Eight until such time as the
Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S.
Government Obligations in accordance with this Article Eight; provided, that if
the Issuers have made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Issuers shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
U.S. Legal Tender or U.S. Government Obligations held by the Trustee or Paying
Agent.

                                  ARTICLE NINE

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

         Section 9.1 Without Consent of Holders. Subject to Section 9.3, the
Issuers, the Guarantors and the Trustee, together, may amend or supplement this
Indenture, the Securities or the Guarantees without notice to or consent of any
Securityholder:

         (1)  to cure any ambiguity, defect or inconsistency;

         (2) to evidence the succession in accordance with Article Five hereof
of another Person to an Issuer and the assumption by any such successor of the
covenants of such Issuer herein and in the Securities;

         (3) to provide for uncertificated Securities in addition to or in place
of certificated Securities;

         (4) to make any other change that does not adversely affect the rights
of any Securityholders hereunder in any material respect;

         (5) to comply with any requirements of the Commission in connection
with the qualification of this Indenture under the TIA; or

                                      -70-

<PAGE>   75

         (6) to add or release any Guarantor pursuant to the terms of this
Indenture;

provided that each Issuer has delivered to the Trustee an Opinion of Counsel and
an Officers' Certificate, each stating that such amendment or supplement
complies with the provisions of this Section 9.1.

         Section 9.2 With Consent of Holders. Subject to Sections 6.7 and 9.3,
the Issuers, the Guarantors and the Trustee, together, with the written consent
of the Holder or Holders of at least a majority in aggregate principal amount of
the outstanding Securities, may amend or supplement this Indenture, the
Securities or the Guarantees, without notice to any other Securityholders.
Subject to Sections 6.7 and 9.3, the Holder or Holders of a majority in
aggregate principal amount of the outstanding Securities may waive compliance by
the Issuers or the Guarantors with any provision of this Indenture, the
Securities or the Guarantees without notice to any other Securityholder. Without
the consent of each Securityholder affected, however, no amendment, supplement
or waiver, including a waiver pursuant to Section 6.4, may:

         (1) reduce the amount of Securities the Holders of which 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 default interest, on any Securities;

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

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

         (5) make any change in provisions of this Indenture protecting the
right of each Holder to receive payment of principal of and interest on such
Security on or after the due date thereof or to bring suit to enforce such
payment;

         (6) modify or change any provision of this Indenture or the related
definitions affecting the subordination or ranking of the Securities or any
Guarantee in a manner which adversely affects the Holders; or

         (7) release (i) Parent or (ii) any Guarantor that is a Significant
Subsidiary of Parent or an Issuer from any of its obligations under its
Guarantee or this Indenture otherwise than in accordance with the terms of this
Indenture.

         It shall not be necessary for the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment, supplement
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

         After an amendment, supplement or waiver under this Section 9.2 becomes
effective, the Issuers shall mail to the Holders affected thereby a notice
briefly describing the amendment,

                                      -71-

<PAGE>   76

supplement or waiver. Any failure of the Issuers to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

         Section 9.3 Effect on Senior Debt. No amendment of, or supplement or
waiver to, this Indenture shall adversely affect the rights of any holder of
Senior Debt or Guarantor Senior Debt under Article Ten or Article Twelve, as the
case may be, of this Indenture, without the consent of such holder.

         Section 9.4 Compliance with TIA. From the date on which this Indenture
is qualified under the TIA, every amendment, waiver or supplement of this
Indenture, the Securities or the Guarantees shall comply with the TIA as then in
effect.

         Section 9.5 Revocation and Effect of Consents. Until an amendment,
waiver or supplement becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's
Security, even if notation of the consent is not made on any Security. However,
any such Holder or subsequent Holder may revoke the consent as to his Security
or portion of his Security by notice to the Trustee or the Issuers received
before the date on which the Trustee receives Officers' Certificates from the
Issuers certifying that the Holders of the requisite principal amount of
Securities have consented (and not theretofore revoked such consent) to the
amendment, supplement or waiver.

         The Issuers may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver which record date shall be at least 30 days prior to the
first solicitation of such consent. If a record date is fixed, then
notwithstanding the last sentence of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to revoke any consent previously
given, whether or not such Persons continue to be Holders after such record
date. No such consent shall be valid or effective for more than 90 days after
such record date.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(1) through (7) of Section 9.2, in which case, the amendment, supplement or
waiver shall bind only each Holder of a Security who has consented to it and
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security; provided, that any such
waiver shall not impair or affect the right of any Holder to receive payment of
principal of and interest on a Security, on or after the respective due dates
expressed in such Security, or to bring suit for the enforcement of any such
payment on or after such respective dates without the consent of such Holder.

         Section 9.6 Notation on or Exchange of Securities. If an amendment,
supplement or waiver changes the terms of a Security, the Issuers may require
the Holder of the Security to deliver it to the Trustee. The Issuers shall
provide the Trustee with an appropriate notation on the Security about the
changed terms and cause the Trustee to return it to the Holder at the Issuers'
expense. Alternatively, if the Issuers or the Trustee so determine, in exchange
for the Security

                                      -72-

<PAGE>   77

the Issuers shall issue and the Trustee shall authenticate a new Security that
reflects the changed terms. Failure to make the appropriate notation or issue a
new Security shall not affect the validity and effect of such amendment,
supplement or waiver.

         Section 9.7 Trustee To Sign Amendments, Etc. The Trustee shall execute
any amendment, supplement or waiver authorized pursuant to this Article Nine;
provided, that the Trustee may, but shall not be obligated to, execute any such
amendment, supplement or waiver which affects the Trustee's own rights, duties
or immunities under this Indenture. The Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of Counsel and an
Officers' Certificate from each Issuer each stating that the execution of any
amendment, supplement or waiver authorized pursuant to this Article Nine is
authorized or permitted by this Indenture and constituted the legal, valid and
binding obligations of the Issuers enforceable in accordance with its terms.
Such Opinions of Counsel shall be at the expense of the Issuers.

                                   ARTICLE TEN

                           SUBORDINATION OF SECURITIES

         Section 10.1 Securities Subordinated to Senior Debt. Anything herein to
the contrary notwithstanding, each Issuer, for itself and its successors, and
each Holder, by his or her acceptance of Securities, agrees that the payment of
all obligations owing to the Holders in respect of the Securities is
subordinated, to the extent and in the manner provided in this Article Ten, to
the prior payment in full in cash or Cash Equivalents, or such payment duly
provided for to the satisfaction of the holders of Senior Debt, of all
obligations on Senior Debt (including the obligations with respect to the Senior
Secured Credit Agreement). Notwithstanding the foregoing, payments and
distributions made relating to the Securities pursuant to the trust described
under Article Eight shall not, so long as the conditions specified in Article
Eight (without any waiver or modification of the requirement that the deposits
pursuant thereto do not conflict with the terms of the Senior Secured Credit
Agreement or any other Senior Debt) are satisfied on the date of any deposit
pursuant to said trust, be so subordinated in right of payment.

         This Article Ten shall constitute a continuing offer to all Persons who
become holders of, or continue to hold, Senior Debt, and such provisions are
made for the benefit of the holders of Senior Debt and such holders are made
obligees hereunder and any one or more of them may enforce such provisions.

         Section 10.2 Suspension of Payment When Senior Debt Is in Default. (a)
If any default occurs and is continuing in the payment when due, whether at
maturity, upon any redemption, by declaration or otherwise, of any principal of,
interest on, unpaid drawings for letters of credit issued in respect of, or
regularly accruing fees with respect to, any Senior Debt (a "Payment Default"),
then no payment or distribution of any kind or character shall be made by or on
behalf of the Issuers or any other Person on behalf of any of them with respect
to any obligation on or relating to the Securities or to acquire any of the
Securities for cash or property or otherwise.

                  (b) If any other event of default (other than a Payment
Default) occurs and is continuing with respect to any Designated Senior Debt (as
such event of default is defined in the

                                      -73-
<PAGE>   78

instrument creating or evidencing such Designated Senior Debt) permitting the
holders of such Designated Senior Debt then outstanding to accelerate the
maturity thereof (a "Non-payment Default") and if the Representative for the
respective issue of Designated Senior Debt gives notice of the event of default
to the Trustee stating that such notice is a payment blockage notice (a "Payment
Blockage Notice"), then, unless and until all events of default have been cured
or waived or have ceased to exist or the Trustee receives notice thereof from
the Representative for the respective issue of Designated Senior Debt
terminating the Payment Blockage Period (as defined below), during the 180 days
after the delivery of such Payment Blockage Notice (the "Payment Blockage
Period"), neither the Issuers nor any other Person on their behalf shall (x)
make any payment of any kind or character with respect to any obligation on or
with respect to the Securities or (y) acquire any of the Securities for cash or
property or otherwise. Notwithstanding anything herein to the contrary, (x) in
no event will a Payment Blockage Period extend beyond 180 days from the date the
applicable Payment Blockage Notice is received by the Trustee and (y) only one
such Payment Blockage Period may be commenced within any period of 360
consecutive days. For all purposes of this Section 10.2(b), no event of default
which existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Debt shall be, or be made,
the basis for the commencement of a second Payment Blockage Period by the
Representative of such Designated Senior Debt whether or not within a period of
360 consecutive days, unless such event of default shall have been cured or
waived for a period of not less than 90 consecutive days (it being acknowledged
that any subsequent action, or any breach of any financial covenants for a
period commencing after the date of commencement of such Payment Blockage Period
that, in either case, would give rise to an event of default pursuant to any
provisions under which an event of default previously existed or was continuing
shall constitute a new event of default for this purpose).

                  (c) In the event that, notwithstanding the foregoing, any
payment shall be received by the Trustee or any Holder when such payment is
prohibited by the foregoing provisions of this Section 10.2, such payment shall
be held for the benefit of, and shall be paid over or delivered to, the holders
of Senior Debt (pro rata to such holders on the basis of the respective amount
of Senior Debt held by such holders) or their respective Representatives, as
their respective interests may appear. The Trustee shall be entitled to rely on
information regarding amounts then due and owing on the Senior Debt, if any,
received from the holders of Senior Debt (or their Representatives) or, if such
information is not received from such holders or their Representatives, from the
Issuers and only amounts included in the information provided to the Trustee
shall be paid to the holders of Senior Debt.

                  Nothing contained in this Article Ten shall limit the right of
the Trustee or the Holders of Securities to take any action to accelerate the
maturity of the Securities pursuant to Section 6.2 or to pursue any rights or
remedies hereunder; provided, that all Senior Debt thereafter due or declared to
be due shall first be paid in full in cash or Cash Equivalents before the
Holders are entitled to receive any payment of any kind or character with
respect to obligations on the Securities.

         Section 10.3 Securities Subordinated to Prior Payment of All Senior
Debt on Dissolution, Liquidation or Reorganization of an Issuer. (a) Upon any
payment or distribution of assets of the Issuers of any kind or character,
whether in cash, property or securities, to creditors upon any total or partial
liquidation, dissolution, winding-up, reorganization, assignment for the benefit
of creditors or marshaling of assets of an Issuer or in a bankruptcy,
reorganization, insolvency, receivership or other similar proceeding relating to
an Issuer or its property, whether voluntary or involuntary, all obligations due
or to become due upon all Senior Debt shall first be paid in full in cash or
Cash Equivalents, or such payment duly provided for to the satisfaction of the
holders of Senior Debt, before any payment or distribution of any kind or
character is made on account of any obligation on or relating to the Securities,
or for the acquisition of any of the Securities for cash or property or
otherwise. Upon any such dissolution, winding-up, liquidation, reorganization,
receivership or similar proceeding, any payment or distribution of assets of an
Issuer of any kind or character, whether in cash, property or securities, to
which the Holders of the Securities or the Trustee under this Indenture would be
entitled, except for the provisions hereof, shall be paid by such Issuer or by
any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the Holders or by the Trustee under
this Indenture if received by them, directly to the holders of Senior Debt (pro
rata to such holders on the basis of the respective amounts of Senior Debt held
by such holders) or their respective Representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior Debt may have
been issued, as their respective interests may appear, for application to the
payment of Senior Debt remaining unpaid until all such Senior Debt has been paid
in full in cash or Cash Equivalents after giving effect to any concurrent
payment, distribution or provision therefor to or for the holders of Senior
Debt.

         (b) To the extent any payment of Senior Debt (whether by or on behalf
of an Issuer, as proceeds of security or enforcement of any right of setoff or
otherwise) is declared to be fraudulent or preferential, set aside or required
to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or
other similar Person under any bankruptcy, insolvency, receivership, fraudulent
conveyance or similar law, then, if such payment is recovered by, or paid over
to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person, the Senior Debt or part thereof originally intended to be
satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred.

         (c) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of an Issuer of any kind or character, whether in cash,
property or securities, shall be received by any Holder when such payment or
distribution is prohibited by this Section 10.3, such payment or distribution
shall be held for the benefit of, and shall be paid over or delivered to, the
holders of Senior Debt (pro rata to such holders on the basis of the respective
amount of Senior Debt held by such holders) or their respective Representatives,
or to the trustee or trustees under any indenture pursuant to which any of such
Senior Debt may have been issued, as their respective interests may appear, for
application to the payment of Senior Debt remaining unpaid until all such Senior
Debt has been paid in full in cash or Cash Equivalents, after giving effect to
any concurrent payment, distribution or provision therefor to or for the holders
of such Senior Debt.

         (d) The consolidation of an Issuer with, or the merger of an Issuer
with or into, another corporation, partnership, trust or limited liability
company or the liquidation or dissolution of an Issuer following the conveyance
or transfer of all or substantially all of its assets, to another corporation,
partnership, trust or limited liability company upon the terms and conditions
provided in Article Five hereof and as long as permitted under the terms of the
Senior Debt shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section if such other corporation shall,
as a part of such consolidation, merger, conveyance or transfer, assume such
Issuer's obligations hereunder in accordance with Article Five hereof.

         Section 10.4 Payments May Be Paid Prior to Dissolution. Nothing
contained in this Article Ten or elsewhere in this Indenture shall prevent (i)
the Issuers, except under the conditions described in Sections 10.2 and 10.3,
from making payments at any time for the purpose of making payments of principal
of and interest on the Securities, or from depositing with the Trustee any
moneys for such payments, or (ii) in the absence of actual knowledge by the
Trustee that a given payment would be prohibited by Section 10.2 or 10.3, the
application by the Trustee of any moneys deposited with it for the purpose of
making such payments of principal of, and interest on, the Securities to the
Holders entitled thereto unless at least two Business Days prior to the date
upon which such payment would otherwise become due and payable a Trust Officer
shall have actually received the written notice provided for in the first
sentence of Section 10.2(b) or in Section 10.7 (provided, that notwithstanding
the foregoing, the Holders receiving any payments made in contravention of
Section 10.2 and/or 10.3 (and any such payments) shall otherwise be subject to
the provisions of Section 10.2 and Section 10.3). The Issuers shall give prompt
written notice to the Trustee of any dissolution, winding-up, liquidation or
reorganization of the Issuers, although any delay or failure to give any such
notice shall have no effect on the subordination provisions contained herein.

         Section 10.5 Holders To Be Subrogated to Rights of Holders of Senior
Debt. Subject to the payment in full in cash or Cash Equivalents of all Senior
Debt, the Holders of the Securities shall be subrogated to the rights of the
holders of Senior Debt to receive payments or distributions of cash, property or
securities of the Issuers applicable to the Senior Debt until the Securities
shall be paid in full; and, for the purposes of such subrogation, no such
payments or distributions to the holders of the Senior Debt by or on behalf of
the Issuers, or by or on behalf of the Holders by virtue of this Article Ten,
which otherwise would have been made to the Holders shall, as between the
Issuers and the Holders, be deemed to be a payment by the Issuers to or on
account of the Senior Debt, it being understood that the provisions of this
Article Ten are and are intended solely for the purpose of defining the relative
rights of the Holders, on the one hand, and the holders of Senior Debt, on the
other hand.

         Section 10.6 Obligation of the Issuers Unconditional. Nothing contained
in this Article Ten or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as among the Issuers, their creditors other than
the holders of Senior Debt, and the Holders, the obligation of the Issuers,
which is absolute and unconditional, to pay to the Holders the principal of and
any interest on the Securities as and when the same shall become due and payable
in accordance with their terms, or is intended to or shall affect the relative
rights of the Holders and creditors of the Issuers other than the holders of the
Senior Debt, nor shall anything herein or therein prevent the

                                      -76-

<PAGE>   81

Holder of any Security or the Trustee on its behalf from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, in respect of cash, property or securities of the Issuers
received upon the exercise of any such remedy.

         Section 10.7 Notice to Trustee. Each Issuer shall give prompt written
notice to the Trustee of any fact known to such Issuer which would prohibit the
making of any payment to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article Ten, although any delay or failure to give any
such notice shall have no effect on the subordination provisions contained
herein. Regardless of anything to the contrary contained in this Article Ten or
elsewhere in this Indenture, the Trustee shall not be charged with knowledge of
the existence of any default or event of default with respect to any Senior Debt
or of any other facts which would prohibit the making of any payment to or by
the Trustee unless and until the Trustee shall have received notice in writing
from an Issuer, or from a holder of Senior Debt or a Representative therefor
and, prior to the receipt of any such written notice, the Trustee shall be
entitled to assume (in the absence of actual knowledge to the contrary) that no
such facts exist. The Trustee shall be entitled to rely on the delivery to it of
any notice pursuant to this Section 10.7 to establish that such notice has been
given by a holder of Senior Debt (or a trustee thereof).

         In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of
Senior Debt to participate in any payment or distribution pursuant to this
Article Ten, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amounts of Senior Debt held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article Ten, and if such evidence is not furnished the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

         Section 10.8 Reliance on Judicial Order or Certificate of Liquidating
Agent. Upon any payment or distribution of assets of an Issuer referred to in
this Article Ten, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders of the Securities shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any
insolvency, bankruptcy, receivership, dissolution, winding-up, liquidation,
reorganization or similar case or proceeding is pending, or upon a certificate
of the receiver, trustee in bankruptcy, liquidating trustee, assignee for the
benefit of creditors, agent or other person making such payment or distribution,
delivered to the Trustee or the Holders of the Securities, for the purpose of
ascertaining the persons entitled to participate in such payment or
distribution, the holders of the Senior Debt and other Indebtedness of the
Issuers, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
Ten.

         Section 10.9 Trustee's Relation to Senior Debt. The Trustee and any
agent of an Issuer or the Trustee shall be entitled to all the rights set forth
in this Article Ten with respect to any Senior Debt which may at any time be
held by it in its individual or any other capacity to the

                                      -77-

<PAGE>   82
same extent as any other holder of Senior Debt and nothing in this Indenture
shall deprive the Trustee or any such agent of any of its rights as such holder.

         With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Ten, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt.

         Whenever a distribution is to be made or a notice given to holders or
owners of Senior Debt, the distribution may be made and the notice may be given
to their Representative, if any.

         Section 10.10 Subordination Rights Not Impaired by Acts or Omissions of
an Issuer or Holders of Senior Debt. No right of any present or future holders
of any Senior Debt to enforce subordination as provided herein shall at any time
in any way be prejudiced or impaired by any act or failure to act on the part of
an Issuer or by any act or failure to act, in good faith, by any such holder, or
by any noncompliance by an Issuer with the terms of this Indenture, regardless
of any knowledge thereof which any such holder may have or otherwise be charged
with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee, without incurring responsibility to the
Trustee or the Holders of the Securities and without impairing or releasing the
subordination provided in this Article Ten or the obligations hereunder of the
Holders of the Securities to the holders of the Senior Debt, do any one or more
of the following: (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, Senior Debt, or otherwise amend or
supplement in any manner Senior Debt, or any instrument evidencing the same or
any agreement under which Senior Debt is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Senior Debt; and (iv) exercise or refrain from
exercising any rights against the Issuers and any other Person.

         Section 10.11 Securityholders Authorize Trustee To Effectuate
Subordination of Securities. Each Holder of Securities by its acceptance thereof
authorizes and expressly directs the Trustee on its behalf to take such action
as may be necessary or appropriate to effectuate, as between the holders of
Senior Debt and the Holders of Securities, the subordination provided in this
Article Ten, and appoints the Trustee its attorney-in-fact for such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of an Issuer (whether in bankruptcy, insolvency, receivership,
reorganization or similar proceedings or upon an assignment for the benefit of
credits or otherwise) tending towards liquidation of the business and assets of
an Issuer, the filing of a claim for the unpaid balance of its Securities and
accrued interest in the form required in those proceedings.

         If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding prior to 30 days before the expiration of the
time to file such claim or claims, then the holders of the Senior Debt or its
Representative are or is hereby authorized to have the right to

                                      -78-

<PAGE>   83

file and are or is hereby authorized to file an appropriate claim for and on
behalf of the Holders of said Securities. Nothing herein contained shall be
deemed to authorize the Trustee or any holder of Senior Debt or its
Representative to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee or the holders of Senior Debt or their Representative to vote in
respect of the claim of any Holder in any such proceeding.

         Section 10.12 This Article Ten Not To Prevent Events of Default. The
failure to make a payment on account of principal of or interest on the
Securities by reason of any provision of this Article Ten will not be construed
as preventing the occurrence of an Event of Default.

         Section 10.13 Trustee's Compensation Not Prejudiced. Nothing in this
Article Ten will apply to amounts due to the Trustee pursuant to other sections
of this Indenture.

                                 ARTICLE ELEVEN

                             GUARANTEE OF SECURITIES

         Section 11.1 Unconditional Guarantee. Subject to the provisions of this
Article Eleven, each of the Guarantors hereby, jointly and severally,
unconditionally and irrevocably guarantees, on a senior subordinated basis (such
guarantees to be referred to herein as a "Guarantee") to each Holder of a
Security authenticated and delivered by the Trustee and to the Trustee and its
successors and assigns, irrespective of the validity and enforceability of this
Indenture, the Securities or the obligations of the Issuers or any other
Guarantors to the Holders or the Trustee hereunder or thereunder, that: (a) the
principal of, premium, if any, and interest on the Securities shall be duly and
punctually paid in full when due, whether at maturity, upon redemption at the
option of Holders pursuant to the provisions of the Securities relating thereto,
by acceleration or otherwise, and interest on the overdue principal and (to the
extent permitted by law) interest, if any, on the Securities and all other
obligations of the Issuers or the Guarantors to the Holders or the Trustee
hereunder or thereunder (including amounts due the Trustee under Section 7.7
hereof) and all other obligations shall be promptly paid in full or performed,
all in accordance with the terms hereof and thereof; and (b) in case of any
extension of time of payment or renewal of any Securities or any of such other
obligations, the same shall be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at maturity, by
acceleration or otherwise. Failing payment when due of any amount so guaranteed,
or failing performance of any other obligation of the Issuers to the Holders
under this Indenture or under the Securities, for whatever reason, each
Guarantor shall be obligated to pay, or to perform or cause the performance of,
the same immediately. An Event of Default under this Indenture or the Securities
shall constitute an event of default under this Guarantee, and shall entitle the
Holders of Securities to accelerate the obligations of the Guarantors hereunder
in the same manner and to the same extent as the obligations of the Issuers.

         Each of the Guarantors hereby agrees that its obligations hereunder
shall be unconditional, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of

                                      -79-
<PAGE>   84


the Securities with respect to any provisions hereof or thereof, any release of
any other Guarantor, the recovery of any judgment against an Issuer, any action
to enforce the same, whether or not a Guarantee is affixed to any particular
Security, or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor. Each of the Guarantors hereby
waives the benefit of diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of an Issuer, any
right to require a proceeding first against an Issuer, protest, notice and all
demands whatsoever and covenants that its Guarantee shall not be discharged
except by complete performance of the obligations contained in the Securities,
this Indenture and this Guarantee. This Guarantee is a guarantee of payment and
not of collection. If any Holder or the Trustee is required by any court or
otherwise to return to the Issuers or to any Guarantor, or any custodian,
trustee, liquidator or other similar official acting in relation to an Issuer or
such Guarantor, any amount paid by an Issuer or such Guarantor to the Trustee or
such Holder, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. Each Guarantor further agrees that, as
between it, on the one hand, and the Holders of Securities and the Trustee, on
the other hand, (a) subject to this Article Eleven, the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Six
hereof for the purposes of this Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (b) in the event of any acceleration of such obligations
as provided in Article Six hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by the Guarantors for the
purpose of this Guarantee.

         No stockholder, officer, director, employee or incorporator, past,
present or future, or any Guarantor, as such, shall have any personal liability
under this Guarantee by reason of his, her or its status as such stockholder,
officer, director, employee or incorporator.

         Each Guarantor that makes a payment or distribution under a Guarantee
shall be entitled to a contribution from each other Guarantor on a pro rata
basis, based on the net assets of each Guarantor, determined in accordance with
GAAP.

         Section 11.2 Limitations on Guarantees. The Obligations of each
Guarantor under its Guarantee are limited to the maximum amount which, after
giving effect to all other contingent and fixed liabilities of such Guarantor
(including without limitation, its guarantee of obligations in respect of the
Senior Secured Credit Agreement and any other Guarantor Senior Debt) and after
giving effect to any collections from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under its
Guarantee or pursuant to its contribution obligations under this Indenture, will
result in the obligations of such Guarantor under the Guarantee not constituting
a fraudulent conveyance or fraudulent transfer under federal or state law.

         Section 11.3 Execution and Delivery of Guarantee. To further evidence
the Guarantee set forth in Section 11.1, each Guarantor hereby agrees that a
notation of such Guarantee, substantially in the form of Exhibit E, shall be
endorsed on each Security authenticated and delivered by the Trustee. Such
Guarantee shall be executed on behalf of each Guarantor by either manual or
facsimile signature of one Officer of each Guarantor who shall have been duly


                                      -80-
<PAGE>   85

authorized to so execute by all requisite corporation action. The validity and
enforceability of any Guarantee shall not be affected by the fact that it is not
affixed to any particular Security.

         Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 11.1 shall remain in full force and effect notwithstanding any failure
to endorse on each Security a notation of such Guarantee.

         If an Officer of a Guarantor whose signature is on this Indenture or a
Guarantee no longer holds that office at the time the Trustee authenticates the
Security on which such Guarantee is endorsed or at any time thereafter, such
Guarantor's Guarantee of such Security shall nevertheless be valid.

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of each Guarantor.

         Section 11.4 Release of a Guarantor. (a) Upon the sale or disposition
of all of the Capital Stock of a Guarantor by an Issuer, in a transaction or
series of related transactions that either (i) does not constitute an Asset Sale
or (ii) constitutes an Asset Sale the Net Cash Proceeds of which are applied in
accordance with Section 4.16, or upon the consolidation or merger of a Guarantor
(other than Parent) with or into any Person in compliance with Article Five (in
each case, other than to or into an Issuer or an Affiliate of an Issuer), or if
any Guarantor is dissolved or liquidated in accordance with this Indenture, such
Guarantor's Guarantee will be automatically discharged and released from all
obligations under this Article Eleven without any further action required on the
part of the Trustee or any Holder. Any Guarantor not so released or the entity
surviving such Guarantor, as applicable, shall remain or be liable under its
Guarantee as provided in this Article Eleven.

         (b) The Trustee shall deliver an appropriate instrument evidencing the
release of a Guarantor prepared by the Issuers or such Guarantor upon receipt of
a request by the Issuers or such Guarantor accompanied by an Officers'
Certificate and an Opinion of Counsel certifying compliance with this Section
11.4; provided, that the legal counsel delivering such Opinion of Counsel may
rely as to matters of fact on Officers' Certificates of the Issuers.

         The Trustee shall execute any documents reasonably requested by the
Issuers or a Guarantor in order to evidence the release of such Guarantor from
its obligations under its Guarantee endorsed on the Securities and under this
Article Eleven.

         Except as set forth in Articles Four and Five and this Section 11.4,
nothing contained in this Indenture or in any of the Securities shall prevent
any consolidation or merger of a Guarantor (other than Parent) with or into an
Issuer or another Guarantor or shall prevent any sale or conveyance of the
property of a Guarantor (other than Parent) as an entirety or substantially as
an entirety to an Issuer or another Guarantor.

         (c) Notwithstanding the foregoing, the Guarantee of Parent may not be
released.


                                      -81-

         Section 11.5 Waiver of Subrogation. Until this Indenture is discharged
and all of the Securities are discharged and paid in full, each Guarantor hereby
irrevocably waives and agrees not to exercise any claim or other rights which it
may now or hereafter acquire against an Issuer that arise from the existence,
payment, performance or enforcement of such Issuer's obligations under the
Securities or this Indenture and such Guarantor's obligations under this
Guarantee and this Indenture, in any such instance including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution,
indemnification, and any right to participate in any claim or remedy of the
Holders against an Issuer, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from an Issuer, directly or indirectly, in cash or
other property or by set-off or in any other manner, payment or security on
account of such claim or other rights. If any amount shall be paid to any
Guarantor in violation of the preceding sentence and any amounts owing to the
Trustee or the Holders of Securities under the Securities, this Indenture, or
any other document or instrument delivered under or in connection with such
agreements or instruments, shall not have been paid in full, such amount shall
have been deemed to have been paid to such Guarantor for the benefit of, and
held in trust for the benefit of, the Trustee or the Holders and shall forthwith
be paid to the Trustee for the benefit of itself or such Holders to be credited
and applied to the obligations in favor of the Trustee or the Holders, as the
case may be, whether matured or unmatured, in accordance with the terms of this
Indenture. Each Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated by this Indenture and that
the waiver set forth in this Section 11.5 is knowingly made in contemplation of
such benefits.

         Section 11.6 Immediate Payment. Each Guarantor agrees to make immediate
payment to the Trustee on behalf of the Holders of all obligations in respect of
the Securities owing or payable to the respective Holders upon receipt of a
demand for payment therefor by the Trustee to such Guarantor in writing.

         Section 11.7 No Set-Off. Each payment to be made by a Guarantor
hereunder in respect of the obligations in respect of the Securities shall be
payable in the currency or currencies in which such obligations are denominated,
and shall be made without set-off, counterclaim, reduction or diminution of any
kind or nature.

         Section 11.8 Obligations Absolute. The obligations of each Guarantor
hereunder are and shall be absolute and unconditional and any monies or amounts
expressed to be owing or payable by each Guarantor hereunder which may not be
recoverable from such Guarantor on the basis of a Guarantee shall be recoverable
from such Guarantor as a primary obligor and principal debtor in respect
thereof.

         Section 11.9 Obligations Continuing. The obligations of each Guarantor
hereunder shall be continuing and shall remain in full force and effect until
all the obligations have been paid and satisfied in full. Each Guarantor agrees
with the Trustee that it will from time to time deliver to the Trustee suitable
acknowledgments of this continued liability hereunder and under any other
instrument or instruments in such form as counsel to the Trustee may advise and
as will prevent any action brought against it in respect of any default
hereunder being barred by any statute of


                                      -82-
<PAGE>   87

limitations now or hereafter in force and, in the event of the failure of a
Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and
agent of such Guarantor to make, execute and deliver such written acknowledgment
or acknowledgments or other instruments as may from time to time become
necessary or advisable, in the judgment of the Trustee on the advice of counsel,
to fully maintain and keep in force the liability of such Guarantor hereunder.

         Section 11.10 Obligations Not Reduced. The obligations of each
Guarantor hereunder shall not be satisfied, reduced or discharged solely by the
payment of such principal, premium, if any, interest, fees and other monies or
amounts as may at any time prior to discharge of this Indenture pursuant to
Article Eight be or become owing or payable under or by virtue of or otherwise
in connection with the Securities or this Indenture.

         Section 11.11 Obligations Reinstated. The obligations of each Guarantor
hereunder shall continue to be effective or shall be reinstated, as the case may
be, if at any time any payment which would otherwise have reduced the
obligations of any Guarantor hereunder (whether such payment shall have been
made by or on behalf of an Issuer or by or on behalf of a Guarantor) is
rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy,
liquidation or reorganization of an Issuer or any Guarantor or otherwise, all as
though such payment had not been made. If demand for, or acceleration of the
time for, payment by an Issuer is stayed upon the insolvency, bankruptcy,
liquidation or reorganization of an Issuer, all such Indebtedness otherwise
subject to demand for payment or acceleration shall nonetheless be payable by
each Guarantor as provided herein.

         Section 11.12 Obligations Not Affected. The obligations of each
Guarantor hereunder shall not be affected, impaired or diminished in any way by
any act, omission, matter or thing whatsoever, occurring before, upon or after
any demand for payment hereunder (and whether or not known or consented to by
any Guarantor or any of the Holders) which, but for this provision, might
constitute a whole or partial defense to a claim against any Guarantor hereunder
or might operate to release or otherwise exonerate any Guarantor from any of its
obligations hereunder or otherwise affect such obligations, whether occasioned
by default of any of the Holders or otherwise, including, without limitation:

         (a) any limitation of status or power, disability, incapacity or other
circumstance relating to an Issuer or any other Person, including any
insolvency, bankruptcy, liquidation, reorganization, readjustment, composition,
dissolution, winding-up or other proceeding involving or affecting an Issuer or
any other Person;

         (b) any irregularity, defect, unenforceability or invalidity in respect
of any indebtedness or other obligation of an Issuer or any other Person under
this Indenture, the Securities or any other document or instrument;

         (c) any failure of an Issuer, whether or not without fault on its part,
to perform or comply with any of the provisions of this Indenture or the
Securities, or to give notice thereof to a Guarantor;


                                      -83-
<PAGE>   88

         (d) the taking or enforcing or exercising or the refusal or neglect to
take or enforce or exercise any right or remedy from or against an Issuer or any
other Person or their respective assets or the release or discharge of any such
right or remedy;

         (e) the granting of time, renewals, extensions, compromises,
concessions, waivers, releases, discharges and other indulgences to an Issuer or
any other Person;

         (f) any change in the time, manner or place of payment of, or in any
other term of, any of the Securities, or any other amendment, variation,
supplement, replacement or waiver of, or any consent to departure from, any of
the Securities or this Indenture, including, without limitation, any increase or
decrease in the principal amount of or premium, if any, or interest on any of
the Securities;

         (g) any change in the ownership, control, name, objects, businesses,
assets, capital structure or constitution of an Issuer or a Guarantor;

         (h) any merger or amalgamation of an Issuer or a Guarantor with any
Person or Persons;

         (i) the occurrence of any change in the laws, rules, regulations or
ordinances of any jurisdiction by any present or future action of any
governmental authority or court amending, varying, reducing or otherwise
affecting, or purporting to amend, vary, reduce or otherwise affect, any of the
Obligations in respect of the Securities or the obligations of a Guarantor under
its Guarantee; and

         (j) any other circumstance, including release of the Guarantor pursuant
to Section 11.4 (other than by complete, irrevocable payment) that might
otherwise constitute a legal or equitable discharge or defense of an Issuer
under this Indenture or the Securities or of a Guarantor in respect of its
Guarantee hereunder.

         Section 11.13 Waiver. Without in any way limiting the provisions of
Section 11.1 hereof, each Guarantor hereby waives notice of acceptance hereof,
notice of any liability of any Guarantor hereunder, notice or proof of reliance
by the Holders upon the obligations of any Guarantor hereunder, and diligence,
presentment, demand for payment on any Issuer, protest, notice of dishonor or
non-payment of any of the Obligations, in respect of the securities or other
notice or formalities to any Issuer or any Guarantor of any kind whatsoever.

         Section 11.14 No Obligation To Take Action Against the Issuers. Neither
the Trustee nor any other Person shall have any obligation to enforce or exhaust
any rights or remedies or to take any other steps under any security for the
Obligations or against any Issuer or any other Person or any property of any
Issuer or any other Person before the Trustee is entitled to demand payment and
performance by any or all Guarantors of their liabilities and obligations under
their Guarantees or under this Indenture.


                                      -84-

         Section 11.15 Dealing with the Issuers and Others. The Holders, without
releasing, discharging, limiting or otherwise affecting in whole or in part the
obligations and liabilities of any Guarantor hereunder and without the consent
of or notice to any Guarantor, may

         (a) grant time, renewals, extensions, compromises, concessions,
waivers, releases, discharges and other indulgences to an Issuer or any other
Person;

         (b) take or abstain from taking security or collateral from an Issuer
or from perfecting security or collateral of an Issuer;

         (c) release, discharge, compromise, realize, enforce or otherwise deal
with or do any act or thing in respect of (with or without consideration) any
and all collateral, mortgages or other security given by an Issuer or any third
party with respect to the obligations or matters contemplated by this Indenture
or the Securities;

         (d)  accept compromises or arrangements from an Issuer;

         (e) apply all monies at any time received from an Issuer or from any
security upon such part of the Issuers' obligations in respect of the Securities
as the Holders may see fit or change any such application in whole or in part
from time to time as the Holders may see fit; and

         (f) otherwise deal with, or waive or modify their right to deal with,
an Issuer and all other Persons and any security as the Holders or the Trustee
may see fit.

         Section 11.16 Default and Enforcement. If any Guarantor fails to pay in
accordance with Section 11.6 hereof, the Trustee may proceed in its name as
trustee hereunder in the enforcement of the Guarantee of any such Guarantor and
such Guarantor's obligations thereunder and hereunder by any remedy provided by
law, whether by legal proceedings or otherwise, and to recover from such
Guarantor the obligations.

         Section 11.17 Amendment, Etc. No amendment, modification or waiver of
any provision of this Indenture relating to any Guarantor or consent to any
departure by any Guarantor or any other Person from any such provision will in
any event be effective unless it is signed by such Guarantor and the Trustee.

         Section 11.18 Acknowledgment. Each Guarantor hereby acknowledges
communication of the terms of this Indenture and the Securities and consents to
and approves of the same.

         Section 11.19 Costs and Expenses. Each Guarantor shall pay on demand by
the Trustee any and all costs, fees and expenses (including, without limitation,
legal fees on a solicitor and client basis) incurred by the Trustee, its agents,
advisors and counsel or any of the Holders in enforcing any of their rights
under any Guarantee.

         Section 11.20 No Merger or Waiver; Cumulative Remedies. No Guarantee

<PAGE>   90

the Trustee or the Holders, any right, remedy, power or privilege hereunder or
under this Indenture or the Securities, shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, remedy, power or privilege
hereunder or under this Indenture or the Securities preclude any other or
further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges in the Guarantee and
under this Indenture, the Securities and any other document or instrument
between a Guarantor and/or any Issuer and the Trustee are cumulative and not
exclusive of any rights, remedies, powers and privilege provided by law.

         Section 11.21 Survival of Obligations. Without prejudice to the
survival of any of the other obligations of each Guarantor hereunder, the
obligations of each Guarantor under Section 11.1 shall survive the payment in
full of the obligations of the Issuers in respect of the Securities and shall be

to any defense, right of offset or counterclaim available to or which may be
asserted by any Issuer or any Guarantor.

         Section 11.22 Guarantee in Addition to Other Obligations. The
obligations of each Guarantor under its Guarantee and this Indenture are in

to any of the Holders in relation to this Indenture or the Securities and any
guarantees or security at any time held by or for the benefit of any of them.

         Section 11.23 Severability. Any provision of this Article Eleven which
is prohibited or unenforceable in any jurisdiction shall not invalidate the
remaining provisions and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction unless its removal would substantially defeat the basic
intent, spirit and purpose of this Indenture and this Article Eleven.

         Section 11.24 Successors and Assigns. Each Guarantee shall be binding
upon and inure to the benefit of each Guarantor and the Trustee and the other
Holders and their respective successors and permitted assigns, except that no
Guarantor may assign any of its obligations hereunder or thereunder.

                                 ARTICLE TWELVE

                           SUBORDINATION OF GUARANTEE

         Section 12.1 Guarantee Obligations Subordinated to Guarantor Senior
Debt. Anything herein to the contrary notwithstanding, each of the Guarantors,
for itself and its successors, and each Holder, by his or her acceptance of
Guarantees, agrees that the payment of all obligations owing to the Holders in
respect of its Guarantee (collectively, as to any Guarantor, its "Guarantee
Obligations") is subordinated, to the extent and in the manner provided in this
Article Twelve, to the prior payment in full in cash or Cash Equivalents, or
such payment duly provided for to the satisfaction of the holders of Guarantor
Senior Debt, of all obligations on Guarantor Senior Debt of such Guarantor.

         This Article Twelve shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Guarantor Senior Debt, and such
provisions are made for the benefit of the holders of Guarantor Senior Debt and
such holders are made obligees hereunder and any one or more of them may enforce
such provisions.

         Section 12.2 Suspension of Guarantee Obligations When Guarantor Senior
Debt Is in Default. (a) If any default occurs and is continuing in the payment
when due, whether at maturity, upon any redemption, by declaration or otherwise,
of any principal of, interest on, unpaid drawings for letters of credit issued
in respect of, or regularly accruing fees with respect to, any Guarantor Senior
Debt, then no payment of any kind or character shall be made by or on behalf of
such Guarantor or any other Person on its behalf with respect to any Guarantee
Obligations or to acquire any of the Securities for cash or property or
otherwise and until such Payment Default shall have been cured or waived or
shall have ceased to exist or such Guarantor Senior Debt shall have been
discharged or paid in full in cash or Cash Equivalents.

         (b) At any time while any Payment Blockage Period is in existence,
neither any Guarantor nor any other Person on any Guarantor's behalf shall (x)
make any payment of any kind or character with respect to any obligations on its
Guarantee or (y) acquire any of the Securities for cash or otherwise.

         (c) In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee or any Holder when such payment is prohibited by the
foregoing provisions of this Section 12.2, such payment shall be held for the
benefit of, and shall be paid over or delivered to, the holders of Guarantor
Senior Debt (pro rata to such holders on the basis of the respective amount of
Guarantor Senior Debt held by such holders) or their respective Representatives,
as their respective interests may appear. The Trustee shall be entitled to rely
on information regarding amounts then due and owing on the Guarantor Senior
Debt, if any, received from the holders of Guarantor Senior Debt (or their
Representatives) or, if such information is not received from such holders or
their Representatives, from a Guarantor and only amounts included in the
information provided to the Trustee shall be paid to the holders of Guarantor
Senior Debt.

         Section 12.3 Guarantee Obligations Subordinated to Prior Payment of All
Guarantor Senior Debt on Dissolution, Liquidation or Reorganization of Such
Guarantor. (a) Upon any payment or distribution of assets of any Guarantor of
any kind or character, whether in cash, property or securities, to creditors
upon any total or partial liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling of assets of such
Guarantor or in a bankruptcy, reorganization, insolvency, receivership or other
similar proceeding relating to such Guarantor or its property, whether voluntary
or involuntary, all obligations due or to become due upon all Guarantor Senior
Debt shall first be paid in full in cash or Cash Equivalents, or such payment
duly provided for to the satisfaction of the holders of Guarantor Senior Debt,
before any payment or distribution of any kind or character is made on account
of any Guarantee Obligations or for the acquisition of any of the Securities for
cash or property or otherwise. Upon any such dissolution, winding-up,
liquidation, reorganization, receivership or similar proceeding, any payment or
distribution of assets of such Guarantor of any kind or character, whether in
cash, property or securities, to which the Holders or the Trustee under this
Indenture would be entitled, except for the provisions hereof, shall be paid by
such Guarantor or by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, or by the Holders or
by the Trustee under this Indenture if received by them, directly to the holders
of Guarantor Senior Debt (pro rata to such holders on the basis of the
respective amounts of Guarantor Senior Debt held by such holders) or their
respective Representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Guarantor Senior Debt may have been issued, as
their respective interests may appear, for application to the payment of
Guarantor Senior Debt remaining unpaid until all such Guarantor Senior Debt has
been paid in full in cash or Cash Equivalents after giving effect to any
concurrent payment, distribution or provision therefor to or for the holders of
Guarantor Senior Debt.

         (b) To the extent any payment of Guarantor Senior Debt (whether by or
on behalf of a Guarantor, as proceeds of security or enforcement of any right of
setoff or otherwise) is declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy, liquidating trustee,
agent or other similar Person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then, if such payment is recovered by, or
paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar Person, the Guarantor Senior Debt or part thereof originally
intended to be satisfied shall be deemed to be reinstated and outstanding as if
such payment had not occurred.

         (c) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Issuers of any kind or character, whether in cash,
property or securities, shall be received by any Holder when such payment or
distribution is prohibited by this Section 12.3, such payment or distribution
shall be held for the benefit of, and shall be paid over or delivered to, the
holders of Guarantor Senior Debt (pro rata to such holders on the basis of the
respective amount of Guarantor Senior Debt held by such holders) or their
respective Representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Guarantor Senior Debt may have been issued, as
their respective interests may appear, for application to the payment of
Guarantor Senior Debt remaining unpaid until all such Guarantor Senior Debt has
been paid in

                                      -88-
<PAGE>   93


full in cash or Cash Equivalents, after giving effect to any concurrent payment,
distribution or provision therefor to or for the holders of such Guarantor
Senior Debt.

         (d) The consolidation of any Guarantor with, or the merger of any
Guarantor with or into, another corporation or the liquidation or dissolution of
a Guarantor following the conveyance or transfer of all or substantially all of
its assets to another corporation upon the terms and conditions provided in
Article Five hereof, and as long as permitted under the terms of the Guarantor
Senior Debt shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 12.3 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, assumes
the Guarantee of such Guarantor hereunder in accordance with Article Five
hereof.

         Section 12.4 Payments May Be Paid Prior to Dissolution. Nothing
contained in this Article Twelve or elsewhere in this Indenture shall prevent
(i) any Guarantor, except under the conditions described in Sections 12.2 and
12.3, from making payments at any time for the purpose of making payments on
Guarantee Obligations, or from depositing with the Trustee any moneys for such
payments, or (ii) in the absence of actual knowledge by the Trustee that a given
payment would be prohibited by Section 12.2 or 12.3, the application by the
Trustee of any moneys deposited with it for the purpose of making such payments
on Guarantee Obligations to the Holders entitled thereto unless at least two
Business Days prior to the date upon which such payment would otherwise become
due and payable a Trust Officer shall have actually received the written notice
provided for in the first sentence of Section 10.2(b) or in Section 12.7
(provided, that notwithstanding the foregoing, the Holders receiving any
payments made in contravention of Sections 12.2 and/or 12.3 (and any such
payments) shall otherwise be subject to the provisions of Section 12.2 and
Section 12.3). Each Guarantor shall give prompt written notice to the Trustee of
any dissolution, winding-up, liquidation or reorganization of such Guarantor,
although any delay or failure to give any such notice shall have no effect on
the subordination provisions contained herein.

         Section 12.5 Holders of Guarantee Obligations To Be Subrogated to
Rights of Holders of Guarantor Senior Debt. Subject to the payment in full in
cash or Cash Equivalents of all Guarantor Senior Debt, the Holders of Guarantee
Obligations of any Guarantor shall be subrogated to the rights of the holders of
Guarantor Senior Debt of such Guarantor to receive payments or distributions of
cash, property or securities of such Guarantor applicable to such Guarantor
Senior Debt until all amounts owing on or in respect of the Guarantee
Obligations shall be paid in full; and, for the purposes of such subrogation, no
such payments or distributions to the holders of such Guarantor Senior Debt by
or on behalf of such Guarantor, or by or on behalf of the Holders by virtue of
this Article Twelve, which otherwise would have been made to the Holders shall,
as between such Guarantor and the Holders, be deemed to be a payment by such
Guarantor to or on account of such Guarantor Senior Debt, it being understood
that the provisions of this Article Twelve are and are intended solely for the
purpose of defining the relative rights of the Holders, on the one hand, and the
holders of Guarantor Senior Debt, on the other hand.


                                      -89-
<PAGE>   94

         Section 12.6 Obligations of the Guarantors Unconditional. Nothing
contained in this Article Twelve or elsewhere in this Indenture or in the
Guarantees is intended to or shall impair, as among the Guarantors, their
creditors other than the holders of Guarantor Senior Debt, and the Holders, the
obligation of the Guarantors, which is absolute and unconditional, to pay to the
Holders all amounts due and payable under the Guarantees as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the Holders and creditors of the
Guarantors other than the holders of the Guarantor Senior Debt, nor shall
anything herein or therein prevent any Holder or the Trustee on its behalf from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, in respect of cash, property or
securities of the Guarantors received upon the exercise of any such remedy.

         Section 12.7 Notice to Trustee. Each Guarantor shall give prompt
written notice to the Trustee of any fact known to such Guarantor which would
prohibit the making of any payment to or by the Trustee in respect of the
Guarantees pursuant to the provisions of this Article Twelve, although any delay
or failure to give any such notice shall have no effect on the subordination
provisions contained herein. Regardless of anything to the contrary contained in
this Article Twelve or elsewhere in this Indenture, the Trustee shall not be
charged with knowledge of the existence of any default or event of default with
respect to any Guarantor Senior Debt or of any other facts which would prohibit
the making of any payment to or by the Trustee unless and until the Trustee
shall have received notice in writing from a Guarantor, or from a holder of
Guarantor Senior Debt or a Representative therefor and, prior to the receipt of
any such written notice, the Trustee shall be entitled to assume (in the absence
of actual knowledge to the contrary) that no such facts exist. The Trustee shall
be entitled to rely on the delivery to it of any notice pursuant to this Section
12.7 to establish that such notice has been given by a holder of Senior Debt (or
a trustee thereof).

         In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of
Guarantor Senior Debt to participate in any payment or distribution pursuant to
this Article Twelve, the Trustee may request such Person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amounts of Guarantor Senior
Debt held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article Twelve, and if such evidence is not
furnished the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

         Section 12.8 Reliance on Judicial Order or Certificate of Liquidating
Agent. Upon any payment or distribution of assets of a Guarantor referred to in
this Article Twelve, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders shall be entitled to rely upon any order or decree made
by any court of competent jurisdiction in which any insolvency, bankruptcy,
receivership, dissolution, winding-up, liquidation, reorganization or similar
case or proceeding is pending, or upon a certificate of the trustee in
bankruptcy, liquidating trustee, receiver, assignee for the benefit of
creditors, agent or other person making such payment or distribution, delivered
to the Trustee or the Holders, for the purpose of ascertaining the persons
entitled to participate in such payment or distribution, the holders of the
Guarantor Senior Debt


                                      -90-
<PAGE>   95

and other Indebtedness of such Guarantor, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Twelve.

         Section 12.9 Trustee's Relation to Guarantor Senior Debt. The Trustee
and any agent of a Guarantor or the Trustee shall be entitled to all the rights
set forth in this Article Twelve with respect to any Guarantor Senior Debt which
may at any time be held by it in its individual or any other capacity to the
same extent as any other holder of Guarantor Senior Debt and nothing in this
Indenture shall deprive the Trustee or any such agent of any of its rights as
such holder.

         With respect to the holders of Guarantor Senior Debt, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Twelve, and no implied covenants
or obligations with respect to the holders of Guarantor Senior Debt shall be
read into this Indenture against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of Guarantor Senior Debt.

         Whenever a distribution is to be made or a notice given to holders or
owners of Guarantor Senior Debt, the distribution may be made and the notice may
be given to their Representative, if any.

         Section 12.10 Subordination Rights Not Impaired by Acts or Omissions of
the Guarantors or Holders of Guarantor Senior Debt. No right of any present or
future holders of any Guarantor Senior Debt to enforce subordination as provided
herein shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of any Guarantor or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by any Guarantor with
the terms of this Indenture, regardless of any knowledge thereof which any such
holder may have or otherwise be charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Guarantor Senior Debt may, at any time and from time to time,
without the consent of or notice to the Trustee, without incurring
responsibility to the Trustee or the Holders of the Securities and without
impairing or releasing the subordination provided in this Article Twelve or the
obligations hereunder of the Holders of the Securities to the holders of
Guarantor Senior Debt, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Guarantor Senior Debt, or otherwise amend or supplement in any manner
Guarantor Senior Debt, or any instrument evidencing the same or any agreement
under which Guarantor Senior Debt is outstanding; (ii) sell, exchange, release
or otherwise deal with any property pledged, mortgaged or otherwise securing
Guarantor Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Guarantor Senior Debt; and (iv) exercise or refrain
from exercising any rights against the Guarantors and any other Person.

         Section 12.11 Holders Authorize Trustee To Effectuate Subordination of
Guarantee Obligations. Each Holder of Guarantee Obligations by its acceptance
thereof authorizes and expressly directs the Trustee on its behalf to take such
action as may be necessary or appropriate to effectuate, as between the holders
of Guarantor Senior Debt and the Holders, the subordination provided in this
Article Twelve, and appoints the Trustee its attorney-in-fact for such purposes,


                                      -91-
<PAGE>   96

including, in the event of any dissolution, winding-up, liquidation or
reorganization of any Guarantor (whether in bankruptcy, insolvency,
receivership, reorganization or similar proceedings or upon an assignment for
the benefit of credits or otherwise) tending towards liquidation of the business
and assets of any Guarantor, the filing of a claim for the unpaid balance under
its Guarantee Obligations and accrued interest in the form required in those
proceedings.

         If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding prior to 30 days before the expiration of the
time to file such claim or claims, then the holders of the Guarantor Senior Debt
or their Representative are or is hereby authorized to have the right to file
and are or is hereby authorized to file an appropriate claim for and on behalf
of the Holders of said Guarantee Obligations. Nothing herein contained shall be
deemed to authorize the Trustee or any holder of Guarantor Senior Debt or its
Representative to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Guarantee Obligations or the rights of any Holder thereof, or to
authorize the Trustee or the holders of Guarantor Senior Debt or their
Representative to vote in respect of the claim of any Holder in any such
proceeding.

         Section 12.12 This Article Twelve Not To Prevent Events of Default. The
failure to make a payment on account of principal of or interest on the
Guarantees by reason of any provision of this Article Twelve will not be
construed as preventing the occurrence of an Event of Default.

         Section 12.13 Trustee's Compensation Not Prejudiced. Nothing in this
Article Twelve will apply to amounts due to the Trustee pursuant to other
sections of this Indenture.

         Section 13.10 No Recourse Against Others. 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
respect of the Securities or for any claim based on, in respect of or by reason
of such obligations or their creation; provided, that the foregoing shall in no
way limit the obligations of any Guarantor in respect of the Guarantees. Each
Securityholder by accepting a Security waives and releases all such liability.
Such waiver and release are part of the consideration for the issuance of the
Securities.

         Section 13.11 Successors. All agreements of the Issuers and the
Guarantors in this Indenture, the Securities and the Guarantees shall bind their
respective successors. All agreements of the Trustee in this Indenture shall
bind its successor.

         Section 13.12 Duplicate Originals. All parties may sign any number of
copies of this Indenture. Each signed copy or counterpart shall be an original,
but all of them together shall represent the same agreement.

         Section 13.13 Severability. In case any one or more of the provisions
in this Indenture, in the Securities or in the Guarantees shall be held invalid,
illegal or unenforceable, in any respect for any reason, the validity, legality
and enforceability of any such provision in every other respect and of the
remaining provisions shall not in any way be affected or impaired thereby, it
being intended that all of the provisions hereof shall be enforceable to the
full extent permitted by law.

         Section 13.14 References to Parent's Board of Directors. In the event
that Parent should cease to own and control a majority of the Voting Securities
of NATG, all references herein to Parent's Board of Directors shall thenceforth
be deemed to be references to NATG's Board of Directors.

                              (REVERSE OF SECURITY)

                                NATG HOLDINS, LLC
                               ORIUS CAPITAL CORP.

                        12 3/4% Senior Subordinated Note

                              due February 1, 2010

         1.   Interest.

         The Issuers jointly and severally promise to pay interest on the
principal amount of this Security at the rate per annum shown above. The Issuers
will pay interest semi-annually on August 1 and February 1 of each year (each,
an "Interest Payment Date"), commencing August 1, 2000. Interest on this
Security will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from February 9, 2000. Interest on this
Security will be computed on the basis of a 360-day year of twelve 30-day
months.

         The Issuers shall pay interest on overdue principal from time to time
on demand at the rate borne by this Security plus 1.5% and on overdue
installments of interest (without regard to any applicable grace periods) to the
extent lawful.

         2.   Method of Payment.

         The Issuers shall pay interest on the Securities (except defaulted
interest) to the persons who are the registered Holders at the close of business
on the Record Date immediately preceding the Interest Payment Date even if the
Securities are cancelled on registration of transfer or registration of exchange
after such Record Date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Issuers shall pay principal and interest in
money of the United States that at the time of payment is legal tender for
payment of public and private debts ("U.S. Legal Tender"). However, the Issuers
may pay principal and interest by wire transfer of Federal funds, or interest by
check payable in such U.S. Legal Tender. The Issuers may deliver any such
interest payment to the Paying Agent or to a Holder at the Holder's registered
address.

         3.  Paying Agent and Registrar.

         Initially, the United States Trust Company of New York (the "Trustee")
will act as Paying Agent and Registrar. The Issuers may change any Paying Agent,
Registrar or co-Registrar without notice to the Holders. The Issuers or any of

                                                                          Page 4

This Security is one of a duly authorized issue of Securities of the Issuers
designated as their 12 3/4% Senior Subordinated Notes due 2010 (the
"Securities"). The Securities are treated as a single class of securities under
the Indenture unless otherwise specified in the Indenture. Capitalized terms
herein are used as defined in the Indenture unless otherwise defined herein. The
terms of the Securities include those stated in the Indenture and those made
part of this Indenture by reference to the Trust Indenture Act of 1939 (15
U.S.C. ss.ss. 77aaa-77bbbb) (the "TIA"), as in effect on the Issue Date until
such time as the Indenture is qualified under the TIA, and thereafter as in
effect on the date on which this Indenture is qualified under the TIA.
Notwithstanding anything to the contrary herein, the Securities are subject to
all such terms, and Holders of Securities are referred to the Indenture and the
TIA for a statement of them. The Securities are general obligations of the
Issuers limited in aggregate principal amount to $300.0 million.

         5.   Subordination.

         The Securities are subordinated in right of payment, in the manner and
to the extent set forth in the Indenture, to the prior payment in full in cash
or Cash Equivalents of all Senior Debt of the Issuers, whether outstanding on
the date of the Indenture or thereafter created, incurred, assumed or
guaranteed. Each Holder by his acceptance hereof agrees to be bound by such
provisions and authorizes and expressly directs the Trustee, on his behalf, to
take such action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purposes.

         6.   Optional Redemption.

         The Securities will be redeemable, at the Issuers' option, in whole at
any time or in part from time to time, on and after February 1, 2005, upon not
less than 30 nor more than 60 days' notice, at the following Redemption Prices
(expressed as percentages of the principal amount) if redeemed during the
twelve-month period commencing on February 1 of the years set forth below, plus,

         7.  Optional Redemption upon Equity Offerings.

         At any time, or from time to time, on or prior to February 1, 2003, the
Issuers may, at their option, use the net cash proceeds of one or more Equity
Offerings to redeem up to 35% aggregate principal amount of the Securities
issued pursuant to the Indenture at a Redemption Price equal to 112.750% of the
principal amount thereof, plus accrued and unpaid interest thereon, if any, to
the date of redemption; provided, that after any such redemption the aggregate
principal amount of Securities outstanding must equal at least 65% of the
aggregate principal amount of the Securities issued pursuant to the Indenture.
In order to effect the foregoing redemption with the net cash proceeds of any
Equity Offering, the Issuers shall make such redemption not more than 60 days
after the consummation of any such Equity Offering.

         8.   Notice of Redemption.

         Notice of redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each Holder of Securities to be redeemed
at such Holder's registered address. Securities in denominations of $1,000 may
be redeemed only in whole. The Trustee may select for redemption portions (equal
to $1,000 or any integral multiple thereof) of the principal of Securities that
have denominations larger than $1,000.

         If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption.

         9.   Change of Control Offer.

         Upon the occurrence of a Change of Control, the Issuers will be
required to offer to purchase all of the outstanding Securities at a purchase
price equal to 101% of the principal amount thereof, plus accrued and unpaid
interest, if any, thereon to the date of repurchase.

         10.  Limitation on Asset Sales.

         The Issuers are, subject to certain conditions, obligated to make an
offer to purchase Securities at 100% of their principal amount, plus accrued and
unpaid interest, if any, thereon to the date of repurchase with certain cash
proceeds of certain sales or other dispositions of assets in accordance with the
Indenture.

         11.  Denominations; Transfer; Exchange.

         The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture.

                                                                       EXHIBIT A
                                                                          Page 6

portions thereof selected for redemption, except the unredeemed portion of any
security being redeemed in part.

         12.  Persons Deemed Owners.

         The registered Holder of a Security shall be treated as the owner
thereof for all purposes.

         13.  Unclaimed Funds.

         If funds for the payment of principal or interest remain unclaimed for
two years, the Trustee and the Paying Agent will, subject to certain
requirements, repay the funds to the Issuers at their request. After that, all
liability of the Trustee and such Paying Agent with respect to such funds shall
cease.

         14.  Discharge Prior to Redemption or Maturity.

         The Issuers and the Guarantors may be discharged from their obligations
under the Indenture, the Securities and the Guarantees except for certain
provisions thereof, and may be discharged from obligations to comply with
certain covenants contained in the Indenture, the Securities and the Guarantees,
in each case upon satisfaction of certain conditions specified in the Indenture.

         15.  Amendment; Supplement; Waiver.

         Subject to certain exceptions, the Indenture, the Securities and the
Guarantees may be amended or supplemented with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding, and any existing Default or Event of Default or compliance
with any provision may be waived with the consent of the Holders of a majority
in aggregate principal amount of the Securities then outstanding. Without notice
to or consent of any Holder, the parties thereto may amend or supplement the
Indenture, the Securities and the Guarantees to, among other things, cure any
ambiguity, defect or inconsistency, provide for uncertificated Securities in
addition to or in place of certificated Securities or comply with any
requirements of the Commission in connection with the qualification of the
Indenture under the TIA, or make any other change that does not materially
adversely affect the rights of any Holder of a Security.

         16.  Restrictive Covenants.

         The Indenture contains certain covenants that, among other things,
limit the ability of the NATG and its Restricted Subsidiaries to make Restricted
Payments, to incur Indebtedness, to create Liens, to sell assets, to permit
restrictions on dividends and other payments by Restricted Subsidiaries of the
Issuers to the Issuers, to consolidate, merge or sell all or substantially all
of their assets or to engage in transactions with affiliates. The limitations
are subject to a number of important qualifications and exceptions. The Issuers
must annually report to the Trustee on compliance with such limitations.

         17.  Defaults and Remedies.

         If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate principal amount of Securities then
outstanding may declare all the Securities to be due and payable immediately in
the manner and with the effect provided in the Indenture. Holders of Securities
may not enforce the Indenture, the Securities or the Guarantees except as
provided in the Indenture. The Trustee is not obligated to enforce the
Indenture, the Securities or the Guarantees unless it has received indemnity
satisfactory to it. The Indenture permits, subject to certain limitations
therein provided, Holders of a majority in aggregate principal amount of the
Securities then outstanding to direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders of Securities notice of certain
continuing Defaults or Events of Default if it determines that withholding
notice is in their interest.

         18.  Trustee Dealings with Company.

         The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal
with Parent, the Issuers, their subsidiaries and their respective Affiliates as
if it were not the Trustee.

         19.  No Recourse Against Others.

         No stockholder, director, officer, member, employee or incorporator, as
such, of Parent, the Issuers or any of their subsidiaries shall have any
liability for any obligation of the Issuers in respect of the Securities or for
any claim based on, in respect of or by reason of, such obligations or their
creation; provided, that the foregoing shall in no way limit the obligations of
any Guarantor in respect of its Guarantee. Each Holder of a Security by
accepting a Security waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Securities.

         20.  Authentication.

         This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on this Security.

         21.  Abbreviations and Defined Terms.

         Customary abbreviations may be used in the name of a Holder of a
Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts

conflicts of laws.

Agreement.

subordinated Guarantees made for the benefit of the Holders. Reference is hereby
made to the Indenture for a statement of the respective rights, limitations of
rights, duties and obligations thereunder of the Guarantors, the Trustee and the

liability company, and ORIUS CAPITAL CORP., a Delaware corporation (together,
the "Issuers"), we confirm that:


         1. We have received a copy of the Offering Memorandum (the "Offering

information as we deem necessary in order to make our investment decision. We
acknowledge that we have read and agreed to the matters stated in the section
entitled "Transfer Restrictions" of such Offering Memorandum, including the
restrictions on duplication and circulation of the Offering Memorandum.

         2. We understand that any subsequent transfer of the Securities is
subject to certain restrictions and conditions set forth in the Indenture
relating to the Securities (the "Indenture") as described in the Offering
Memorandum and the undersigned agrees to be bound by, and not to resell, pledge
or otherwise transfer the Securities except in compliance with, such
restrictions and conditions and the Securities Act of 1933, as amended (the
"Securities Act"), and all applicable State securities laws.

         3. We understand that the offer and sale of the Securities have not
been registered under the Securities Act, and that the Securities may not be
offered or sold except as permitted in the following sentence. We agree, on our
own behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell any Securities, we will do so only (i) to Orius
Corp., the Issuers or any of their subsidiaries, (ii) inside the United States
in accordance with Rule 144A under the Securities Act to a "qualified

below) that, prior to such transfer, furnishes (or has furnished on its behalf
by a U.S. broker-dealer) to the Trustee (as defined in the Indenture) a signed
letter containing certain representations and agreements relating to the
restrictions on transfer of the Securities (the form of which letter can be
obtained from the Trustee), (iv) outside the United States in accordance with

statement under the Securities Act, and we further agree to provide to any
person purchasing any of the Securities from us a notice advising such purchaser
that resales of the Securities are restricted as stated herein.

not transfer the Securities to, any pension or welfare plan (as defined in
Section 3 of the Employee Retirement Income Security Act of 1974), except as
permitted in the section entitled "Transfer Restrictions" of the Offering
Memorandum.

         5. We understand that, on any proposed resale of any Securities, we

reasonably require to confirm that the proposed sale complies with the foregoing
restrictions. We further understand that the Securities purchased by us will
bear a legend to the foregoing effect.

         6. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Securities, and we
and any accounts for which we are acting are each able to bear the economic risk
of our or their investment, as the case may be.

         7. We are acquiring the Securities purchased by us for our account or
for one or more accounts (each of which is an institutional "accredited
investor") as to each of which we exercise sole investment discretion.

letter and are irrevocably authorized to produce this letter or a copy hereof to
any interested party in any administrative or legal proceeding or official
inquiry with respect to the matters covered hereby.

"Exchange Offer Registration Statement") on an appropriate registration form
with respect to a registered offer (the "Exchange Offer") to exchange any and
all of the Registrable Notes for a like aggregate principal amount of notes of
the Companies, guaranteed by the Guarantors, that are identical in all material
respects to the Securities (the "Exchange Notes"), except that (i) the Exchange
Notes shall contain no restrictive legend thereon and (ii) interest thereon will
accrue (A) from the later of (1) the last interest payment date on which
interest was paid on the Note surrendered therefor or (2) if the Note is
surrendered for exchange on a date in a period which includes the record date
for an interest payment date to occur on or after the date of such exchange and
as to which interest will be paid, the date of such interest payment, or (B) if
no interest has been paid on such Note, from the Issue Date and which are
entitled to the benefits of the Indenture or a trust indenture which is

Exchange Offer shall comply with all applicable tender offer rules and
regulations under the Exchange Act and other applicable law. The Issuers shall
use their reasonable best efforts to (x) cause the Exchange Offer Registration
Statement to be declared effective under the Securities Act on or before the
Effectiveness Date; (y) keep the Exchange Offer open for at least 20 business
days (or longer if required by applicable law) after the date that notice of the
Exchange Offer is mailed to Holders; and (z) consummate the Exchange Offer on or
prior to the 30th day after the effective date of the Exchange Offer
Registration Statement. If, after the Exchange Offer Registration Statement is
initially declared effective by the SEC, the Exchange Offer or the issuance of
the Exchange Notes thereunder is interfered with by any stop order, injunction
or other order or requirement of the SEC or any other governmental agency or
court, the Exchange Offer Registration Statement shall be deemed not to have
become effective for purposes of this Agreement during the period of such
interference, until the Exchange Offer may legally resume.

     Each Holder that participates in the Exchange Offer will be required, as a
condition to its participation in the Exchange Offer, to represent to the
Issuers in writing (which may be contained in the applicable letter of
transmittal) that: (i) any Exchange Notes to be received by it will be acquired
in the ordinary course of its business, (ii) such Holder has no arrangement or
understanding with any Person to participate in the distribution of the Exchange
Notes in violation of the provisions of the Securities Act, (iii) such Holder is
not an affiliate of the Issuers within the meaning of the Securities Act or, if
such Holder is an affiliate, that it will comply with the registration and
prospectus delivery requirements of the Securities Act applicable to it, (iv) if
such Holder is not a broker-dealer, such Holder is not engaged in, and does not
intend to engage in, the distribution (within the meaning of the Securities Act)
of Exchange Notes, (v) if such Holder is a broker-dealer that will receive
Exchange Notes for its own account in exchange for Notes that were acquired as a
result of market-making or other trading activities, such Holder will deliver a
prospectus in connection with any resale of such Exchange Notes and (vi) the
Holder is not acting

                                       -5-



<PAGE>   7



on behalf of any persons or entities who could not truthfully make the foregoing
representations. Such Holder will also be required to make such other
representations as may be necessary under applicable SEC rules, regulations or
interpretations to render available the use of Form S-4 or any other appropriate
form under the Securities Act.

     Upon consummation of the Exchange Offer in accordance with this Section 2,
the provisions of this Agreement shall continue to apply solely with respect to
Registrable Notes that are Private Exchange Notes, Exchange Notes as to which
Section 2(c)(iv) is applicable and Exchange Notes held by Participating
Broker-Dealers (as defined), and the Issuers shall have no further obligation to
register Registrable Notes (other than Private Exchange Notes and other than in
respect of any Exchange Notes as to which clause 2(c)(iv) hereof applies)
pursuant to Section 3 hereof

     No securities other than the Exchange Notes shall be included in the
Exchange Offer Registration Statement.

     (b) To the extent required by applicable law or SEC policy, the Issuers
shall include within the Prospectus contained in the Exchange Offer Registration
Statement a section entitled "Plan of Distribution," reasonably acceptable to
the Initial Purchasers, which shall contain a summary statement of the positions
taken or policies made by the staff of the SEC (and publicly disseminated) with
respect to the potential "underwriter" status of any broker-dealer that is the
beneficial owner (as defined in Rule l3d-3 under the Exchange Act) of Exchange
Notes received by such broker-dealer in the Exchange Offer (a "Participating
Broker-Dealer") (other than any Notes acquired by it and having the status of an
unsold allotment in the initial distribution). Such "Plan of Distribution"
section shall also expressly permit, to the extent permitted by applicable
policies and regulations of the SEC, the use of the Prospectus by all Persons
subject to the prospectus delivery requirements of the Securities Act,
including, to the extent permitted by applicable policies and regulations of the
SEC, all Participating Broker-Dealers, and include a statement describing the
means by which Participating Broker-Dealers may resell the Exchange Notes in
compliance with the Securities Act.

     In the event that the Issuers receive notice from a Participating
Broker-Dealer within 30 days after the consummation of the Exchange Offer that
such Participating Broker-Dealer holds Notes (other than Notes acquired by it
that have the status of an unsold allotment in the initial distribution
thereof), the Issuers shall use their reasonable best efforts to keep the
Exchange Offer Registration Statement effective and to amend and supplement the
Prospectus contained therein in order to permit such Prospectus to be lawfully
delivered by all Persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as is necessary to comply with applicable
law in connection with any resale of the exchange Notes covered thereby,
provided, such period shall not be required to exceed 270 days, or such longer
period if extended pursuant to the last sentence of Section 5 (the "Applicable
Period").

     If, prior to consummation of the Exchange Offer, the Initial Purchasers
hold any Notes acquired by them that have the status of an unsold allotment in
the initial distribution, the Issuers upon the request of the Initial Purchasers
shall simultaneously with the delivery of the Exchange



                                      -6-



<PAGE>   8



Notes in the Exchange Offer, issue and deliver to the Initial Purchasers, in
exchange (the "Private Exchange") for such Notes held by the Initial Purchasers,
a like principal amount of notes (the "Private Exchange Notes") of the
Companies, guaranteed by the Guarantors, that are identical in all material
respects to the Exchange Notes except for the placement of a restrictive legend
on such Private Exchange Notes. The Private Exchange Notes shall be issued
pursuant to the same indenture as the Exchange Notes and bear the same CUSIP
number as the Exchange Notes, to the extent possible.

     In connection with the Exchange Offer, the Issuers shall:

         (1) mail, or cause to be mailed, to each Holder of record entitled to
         participate in the Exchange Offer a copy of the Prospectus forming
         part of the Exchange Offer Registration Statement, together with an
         appropriate letter of transmittal and related documents;

         (2) use their reasonable best efforts to keep the Exchange Offer open
         for not less than 20 business days after the date that notice of the
         Exchange Offer is mailed to Holders (or longer if required by
         applicable law);

         (3) utilize the services of a depository for the Exchange Offer with an
         address in the Borough of Manhattan, The City of New York;

         (4) permit Holders to withdraw tendered Securities at any time prior to
         the close of business, New York time, on the last business day on which
         the Exchange Offer shall remain open; and

         (5) otherwise comply in all material respects with all applicable laws,
         rules and regulations.

     As soon as reasonably practicable after the close of the Exchange Offer and
the Private Exchange, if any, the Issuers shall:

         (1) accept for exchange all Registrable Notes validly tendered and not
         validly withdrawn pursuant to the Exchange Offer and the Private
         Exchange, if any;

         (2) deliver to the Trustee for cancellation all Registrable Notes so
         accepted for exchange; and

         (3) cause the trustee to authenticate and deliver promptly to each
         Holder of Securities, Exchange Notes or Private Exchange Notes, as the
         case may be, equal in principal amount to the Securities of such Holder
         so accepted for exchange.

     The Exchange Offer and the Private Exchange shall not be subject to any
conditions, other than that (i) the Exchange Offer or the Private Exchange, as
the case may be, does not violate applicable law, statute, rule or regulation or
any applicable interpretation of the staff of the SEC,

                                      -7-


<PAGE>   9


(ii) no action or proceeding shall have been instituted or threatened in any
court or by any governmental agency which might materially impair the ability of
the Issuers to proceed with the Exchange Offer or the Private Exchange, (iii)
all governmental approvals shall have been obtained, which approvals the Issuers
deem necessary for the consummation of the Exchange Offer or the Private
Exchange, (iv) there has not been any material change, or development involving
a prospective material change, in the business or financial affairs of the
Issuers which, in the reasonable judgment of the Issuers, would materially
impair the Issuers' ability to consummate the Exchange Offer or the Private
Exchange, and (v) there has not been proposed, adopted or enacted any law,
statute, rule or regulation which, in the reasonable judgment of the Issuers,
would materially impair the Issuers' ability to consummate the Exchange Offer or
the Private Exchange or have a material adverse effect on the Issuers if the
Exchange Offer or the Private Exchange was consummated. In the event that the
Issuers are unable to consummate the Exchange Offer or the Private Exchange due
to any event listed in clauses (i) through (v) above, the Issuers shall not be
deemed to have breached any covenant under this Section 2; provided, that the
occurrence of any such event shall not prevent the accrual of Additional
Interest.

     The Exchange Notes and the Private Exchange Notes shall be issued under (i)
the Indenture or (ii) an indenture identical in all material respects to the
Indenture and which, in either case, has been qualified under the TIA or is
exempt from such qualification and shall provide that the Exchange Notes shall
not be subject to the transfer restrictions set forth in the Indenture. The
Indenture or such indenture shall provide that the Exchange Notes, the Private
Exchange Notes and the Securities shall vote and consent together on all matters
as one class and that none of the Exchange Notes, the Private Exchange Notes or
the Securities will have the right to vote or consent as a separate class on any
matter.

     (c) If (i) because of any change in law or in currently prevailing
interpretations of the staff of the SEC, the Issuers determine in good faith
that they are not permitted to effect the Exchange Offer, (ii) the Exchange
Offer is not consummated within 255 days of the Issue Date, as extended pursuant
to this agreement, (iii) the holder of Private Exchange Notes so requests in
writing to the Issuers within 60 days after the consummation of the Exchange
Offer, or (iv), in the case of any Holder that participates in the Exchange
Offer, such Holder does not receive Exchange Notes on the date of the exchange
that may be sold without delivering a Prospectus and an Issuer has actual
knowledge of such fact or such Holder delivers written notice of such fact to
Parent or NATG, and in the reasonable opinion of counsel to the Issuers the
Prospectus included in the Exchange Offer Registration Statement is not legally
available for such resales by such Holder, then in the case of each of clauses
(i) to and including (iv) of this sentence, the Issuers shall promptly deliver
to the Holders and the Trustee written notice thereof (the "Shelf Notice") and
shall file a Shelf Registration pursuant to Section 3 hereof

     3. Shelf Registration. If at any time a shelf Notice is delivered as
contemplated by Section 2(c) hereof, then:

     (a) Shelf Registration. The Issuers shall use their reasonable best efforts
to file with the SEC a Registration Statement for an offering to be made on a
continuous basis pursuant to Rule 415 covering all of the Registrable Notes
covered by such Shelf Notice (the "Initial Shelf


                                       -8-



<PAGE>   10


Registration"). The Issuers shall use their reasonable best efforts to file with
the SEC the initial Shelf Registration on or before the applicable Filing Date.
The Initial Shelf Registration shall be on Form S-1 or another appropriate form
permitting registration of such Registrable Notes for resale by Holders in the
manner or manners designated by them (including, without limitation, one
underwritten offering if requested by one or more Holders who together hold at
least $20 million aggregate principal amount of Notes (the "Required Holders")).
The Issuers shall not permit any securities other than the Registrable Notes to
be included in the Initial Shelf Registration or any Subsequent Shelf
Registration (as defined below).

     The Issuers shall, subject to applicable law or applicable interpretations
of the staff of the SEC, use their reasonable best efforts to cause the Initial
Shelf Registration to be declared effective under the Securities Act on or prior
to the Effectiveness Date and to keep the Initial Shelf Registration
continuously effective under the Securities Act until the date which is two
years from the Issue Date or such shorter period ending when (i) all Registrable
Notes covered by the Initial Shelf Registration have been sold in the manner set
forth and as contemplated in the Initial Shelf Registration or cease to be
outstanding, (ii) a Subsequent Shelf Registration covering all of the
Registrable Notes covered by and not sold under the Initial Shelf Registration
or an earlier Subsequent Shelf Registration has been declared effective under
the Securities Act or (iii) all outstanding Registrable Notes cease to be
Registrable Notes (the "Effectiveness Period"), provided, that the Effectiveness
Period in respect of the Initial Shelf Registration shall be extended to the
extent required to permit dealers to comply with the applicable prospectus
delivery requirements of Rule 174 under the Securities Act and as otherwise
provided herein.

     No holder of Registrable Notes may include any of its Registrable Notes in
any Shelf Registration Statement pursuant to this Agreement unless and until
such holder furnishes to the Issuers in writing, within 15 business days after
receipt of a request therefor, such information concerning such Holder required
to be included in any Shelf Registration Statement or Prospectus or preliminary
prospectus included therein. No holder of Registrable Notes shall be entitled to
Additional Interest pursuant to Section 4 hereof unless and until such holder
shall have provided all such information. Each holder of Registrable Notes as to
which any Shelf Registration Statement is being effected agrees to furnish
promptly to the Issuers all information required to be disclosed in order to
make information previously furnished to the Issuers by such Holder not
materially misleading.

     (b) Subsequent Shelf Registrations. If the Initial Shelf Registration or
any Subsequent Shelf Registration ceases to be effective for any reason at any
time during the Effectiveness Period (other than because of the sale of all of
the securities registered thereunder), the Issuers shall use their reasonable
best efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within 45 days of such cessation
of effectiveness use their reasonable best efforts to amend the Initial Shelf
Registration in a manner to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an additional "shelf" Registration Statement
pursuant to Rule 415 covering all of the Registrable Notes covered by and not
sold under the Initial Shelf Registration or an earlier Subsequent Shelf
Registration (each, a "Subsequent Shelf Registration"). If a Subsequent Shelf
Registration is filed, the Issuers shall use their reasonable best efforts to
cause the Subsequent Shelf Registration to be declared effective



                                      -9-



<PAGE>   11





under the Securities Act as soon as practicable after such filing and to keep
such subsequent Shelf Registration continuously effective for a period equal to
the number of days in the Effectiveness Period less the aggregate number of days
during which the Initial Shelf Registration or any Subsequent Shelf Registration
was previously continuously effective. As used herein the term "Shelf
Registration" means the Initial Shelf Registration and any Subsequent Shelf
Registration.

     (c) Supplements and Amendments. The Issuers shall promptly supplement and
amend any Shelf Registration if required by the rules, regulations or
instructions applicable to the registration form used for such Shelf
Registration, if required by the Securities Act, or if reasonably requested by
the Holders of a majority in aggregate principal amount of the Registrable Notes
covered by such Registration Statement or by any underwriter of such Registrable
Notes. The Issuers shall not be required to amend or supplement a Shelf
Registration Statement to reflect additional Holders more than once per fiscal
quarter after it has been declared effective by the Commission.

     (d) Suspension of Shelf Registration Statement. The Issuers' obligation to
keep the Shelf Registration Statement effective and usable for offers and sales
of the Registrable Securities may be suspended by the Issuers in good faith for
valid business reasons, including, without limitation, a pending acquisition or
divestiture of assets. Any such period during which the Issuers fail to keep the
Shelf Registration Statement effective and usable for offers and sales of
Registrable Securities is referred to as a "Suspension Period." A Suspension
Period shall commence on and include the date that the Issuers give notice that
the Shelf Registration Statement is no longer effective or the prospectus
included therein is no longer usable for offers and sales of the Registrable
Securities and shall end on the date when each Holder of Registrable Securities
covered by such registration statement either receives the copies of the
supplemented or amended prospectus contemplated by Section 3(c) hereof or is
advised in writing by the Issuers that the use of the prospectus may be resumed;
provided, that any such suspension shall not prevent the accrual of Additional
Interest.

     4. Additional Interest

     (a) The Issuers and the Initial Purchasers agree that the Holders will
suffer damages if the Issuers fail to fulfill their obligations under Section 2
or Section 3 hereof and that it would not be feasible to ascertain the extent of
such damages with precision. Accordingly, the Issuers agree to pay, as
liquidated damages, additional interest on the Notes ("Additional Interest")
under the circumstances and to the extent set forth below (each of which shall
be given independent effect):

         (i) if (A) neither the Exchange Offer Registration Statement nor the
         Initial Shelf Registration has been filed on or prior to 120 days after
         the Issue Date or (B) notwithstanding that the issuers have consummated
         or will consummate the Exchange Offer, the Issuers are required to file
         a Shelf Registration and such Shelf Registration is not filed on or
         prior to the Filing Date applicable thereto, then, commencing on the
         day after any such Filing Date, Additional Interest shall accrue at a
         rate of 0.50% per annum for the first 90 days immediately following
         each such Filing Date, and such Additional Interest rate shall increase
         by an additional 0.50% per annum at the beginning of each subsequent
         90-day period; or


                                      -10-



<PAGE>   12


         (ii) if (A) neither the Exchange Offer Registration Statement nor the
         Initial Shelf Registration is declared effective by the SEC on or prior
         to the relevant Effectiveness Date or (B) notwithstanding that the
         Issuers have consummated or will consummate the Exchange Offer, the
         Issuers are required to file a Shelf Registration and such Shelf
         Registration is not declared effective by the SEC on or prior to the
         Effectiveness Date in respect of such Shelf Registration, then,
         commencing on the day after such Effectiveness Date, Additional
         Interest shall accrue at a rate of 0.50% per annum for the first 90
         days immediately following each such Effectiveness Date, and such
         Additional Interest rate shall increase by an additional 0.50% per
         annum at the beginning of each subsequent 90-day period; or

         (iii) if (A) the Issuers have not exchanged Exchange Notes for all
         Securities validly tendered in accordance with the terms of 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 has been declared effective and such Shelf Registration
         ceases to be effective at any time during the Effectiveness Period, or
         (C) the Issuers effect a Suspension Period, then in each case,
         Additional Interest shall accrue at a rate of 0.50% per annum for the
         first 90 days commencing on the (x) 31st day after the Issue Date, in
         the case of (A) above, (y) day such Shelf Registration ceases to be
         effective in the case of (B) above or (z) day such Suspension Period
         commences in the case of (C) above, and such Additional Interest rate
         shall increase by an additional 0.50% per annum at the beginning of
         each such subsequent 90-day period;

provided, that Additional Interest on the Notes may not accrue under more than
one of the foregoing clauses (i)-(iii) at any one time and at no time shall the
aggregate amount of Additional Interest exceed 1.50% per annum; provided,
further, however, that (1) upon the filing of the applicable Exchange Offer
Registration Statement or the applicable Shelf Registration Statement as
required hereunder (in the case of clause (i) above of this Section 4(a)), (2)
upon the effectiveness of the Exchange Offer Registration Statement or the
applicable Shelf Registration Statement as required hereunder (in the case of
clause (ii) of this Section 4(a)), or (3) upon (X) the exchange of the
applicable Exchange Notes for all Securities tendered (in the case of clause
(iii)(A) of this Section 4), (Y) the effectiveness of the applicable Shelf
Registration Statement which had ceased to remain effective (in the case of
(iii)(B) of this Section 4(a)) or (Z) the termination of the Suspension Period
(in the case of clause (iii)(A) of this Section 4(a)), Additional Interest on
the Notes in respect of which such events relate as a result of such clause (or
the relevant subclause thereof), as the case may be, shall cease to accrue.

     (b) The Issuers shall notify the Trustee within three business days after
each and every date on which an event occurs in respect of which Additional
Interest is required to be paid (an "Event Date"). Any amounts of Additional
Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be
payable in cash semiannually on each February 1 and August 1, to the Holders on
the January 15 and July 15 (whether or not a business day) immediately preceding
such dates, commencing with the first such date occurring after any such
Additional Interest commences to


                                      -11-



<PAGE>   13

accrue. The amount of Additional Interest will be determined by multiplying the
applicable Additional Interest rate by the principal amount of the Registrable
Notes, multiplied by a fraction, the numerator of which is the number of days
such Additional Interest rate was applicable during such period (determined on
the basis of a 360-day year comprised of twelve 30-day months and, in the case
of a partial month, the actual number of days elapsed), and the denominator of
which is 360.

     5. Registration Procedures. In connection with the filing of any
Registration Statement pursuant to Sections 2 or 3 hereof, the Issuers shall
effect such registrations to permit the sale of the securities covered thereby
in accordance with the intended method or methods of disposition thereof, and
pursuant thereto and in connection with any Registration Statement filed by the
Issuers hereunder each of the Issuers shall:

     (a) Prepare and file with the SEC prior to the applicable Filing Date, a
Registration Statement or Registration Statements as prescribed by Sections 2 or
3 hereof, and use their reasonable best efforts to cause each such Registration
Statement to become effective and remain effective as provided herein; provided,
that, if (1) such filing is pursuant to Section 3 hereof, or (2) a Prospectus
contained in the Exchange Offer Registration Statement filed pursuant to Section
2 hereof is required to be delivered under the Securities Act by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period relating thereto, before filing any Registration Statement or
Prospectus or any amendments or supplements thereto, the Issuers shall, to the
extent permitted by law, furnish to and afford the Holders of the Registrable
Notes included in such Registration Statement (with respect to a Shelf
Registration filed pursuant to Section 3 hereof) or each such Participating
Broker-Dealer identified to the Issuers, as the case may be, their counsel and
the managing underwriters, if any, a reasonable opportunity to review copies of
all such documents (including, if requested in writing, copies of any documents
to be incorporated by reference therein and all exhibits thereto) proposed to be
filed (in each case at least five days prior to such filing, or such later date
as is reasonable under the circumstances). The Issuers shall not file any
Registration Statement or Prospectus or any amendments or supplements thereto if
the Holders of a majority in aggregate principal amount of the Registrable Notes
included in such Registration Statement, or any such Participating
Broker-Dealer, as the case may be, their counsel, or the managing underwriters,
if any, shall reasonably object in writing on a timely basis unless in the
opinion of counsel to the Issuers the filing thereof is required by law.

     (b) Use their reasonable best efforts to prepare and file with the SEC such
amendments and post-effective amendments to each Shelf Registration Statement or
the Exchange Offer Registration Statement, as the case may be, as may be
necessary to keep such Registration Statement continuously effective for the
Effectiveness Period or the Applicable Period, as the case may be; cause the
related Prospectus to be supplemented by any Prospectus supplement required by
applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any
similar provisions then in force) promulgated under the Securities Act; and
comply with the provisions of the Securities Act and the Exchange Act applicable
to each of them with respect to the disposition of all securities covered by
such Registration Statement as so amended or in such Prospectus as so
supplemented and with respect to the subsequent resale of any securities being
sold by a


                                      -12-

<PAGE>   14


Participating Broker-Dealer covered by any such Prospectus. The Issuers shall be
deemed to have used their reasonable best efforts to keep a Registration
Statement effective during the Effectiveness Period or the Applicable Period, as
the case may be, relating thereto, even if the Issuers voluntarily take any
action that results in selling Holders of the Registrable Notes covered thereby
or Participating Broker-Dealers seeking to sell Exchange Notes not being able to
sell such Registrable Notes or such Exchange Notes during that period if such
action is required by applicable law or if the Issuers comply with this
Agreement, including Section 3(d) which shall be applicable to the Exchange
Offer Registration Statement during the applicable period and Section 5(j) and
the last paragraph of this Section 5.

         (c) If (1) a Shelf Registration is filed pursuant to Section 3 hereof,
or (2) a Prospectus contained in the Exchange Offer Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period relating thereto from whom the Issuers have received
written notice that it will be a Participating Broker-Dealer in the Exchange
Offer as contemplated by Section 2 hereof, notify the selling Holders of
Registrable Notes who are named as selling securityholders in the applicable
Shelf Registration Statement, or each such Participating Broker-Dealer, as the
case may be, and the managing underwriters, if any, promptly (but in any event
within five business days), and, if requested by any such persons, confirm such
notice in writing, (i) when a Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to any applicable
Registration Statement or any post-effective amendment, when the same has become
effective under the Securities Act (including in such notice a written statement
that any Holder may, upon request in writing, obtain, at the sole expense of the
Issuers, one conformed copy of such Registration Statement or post-effective
amendment including financial statements and schedules and, if specifically
requested, documents incorporated or deemed to be incorporated by reference and
exhibits), (ii) of the issuance by the SEC of any stop order suspending the
effectiveness of a Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus or the initiation of any
proceedings for that purpose, (iii) if at any time when a prospectus is required
by the Securities Act to be delivered in connection with sales of the
Registrable Notes or resales of Exchange Notes by Participating Broker-Dealers
the representations and warranties of the Issuers contained in any agreement
(including any underwriting agreement) contemplated by Section 5(l) hereof cease
to be true and correct in all material respects, (iv) of the receipt by any
Issuer of any notification with respect to the suspension of the qualification
or exemption from qualification of a Registration Statement or any of the
Registrable Notes or the Exchange Notes to be sold by any Participating
Broker-Dealer for offer or sale in any jurisdiction, or the initiation or
threatening of any proceeding for such purpose, (v) of the happening of any
event, the existence of any condition or any information becoming known that
makes any statement made in such Registration Statement or related Prospectus or
any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires the making of any changes in or
amendments or supplements to such Registration Statement, Prospectus or
documents so that, in the case of the Registration Statement, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading, and that in the case of the Prospectus, it will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein

                                      -13-



<PAGE>   15


or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; provided that such notification need not
specifically identify such event if notification of the occurrence thereof
would, in the reasonable judgment of any Issuer, involve the disclosure of
confidential, nonpublic information, and (vi) of the Issuers' determination that
a post-effective amendment to a Registration Statement would be appropriate.

         (d) If (1) a Shelf Registration is filed pursuant to Section 3 hereof,
or (2) a Prospectus contained in the Exchange Offer Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period relating thereto from whom the Issuers have received
written notice that it will be a Participating Broker-Dealer in the Exchange
Offer as contemplated by Section 2 hereof, use its reasonable best efforts to
prevent the issuance of any order suspending the effectiveness of a Registration
Statement or of any order preventing or suspending the use of a Prospectus or
suspending the qualification (or exemption from qualification) of any of the
Registrable Notes or the Exchange Notes to be sold by any Participating
Broker-Dealer, for sale in any jurisdiction, and, if any such order is issued,
to use its reasonable best efforts to obtain the withdrawal of any such order at
the earliest possible time.

         (e) If a Shelf Registration is filed pursuant to Section 3 and if
requested by the managing underwriter or underwriters (if any) or the Required
Holders, (i) as promptly as reasonably practicable incorporate in a prospectus
supplement or post-effective amendment such information as the managing
underwriter or underwriters (if any), or such Required Holders or counsel for
any of them reasonably request to be included therein, (ii) make all required
filings of such prospectus supplement or such post-effective amendment as soon
as reasonably practicable after the Issuers have received notification of the
matters to be incorporated in such prospectus supplement or post-effective
amendment, and (iii) supplement or make amendments to such Registration
Statement; provided, that the Issuers shall not be required to take any action
pursuant to this paragraph (e) that would, in the opinion of counsel to the
Issuers, violate applicable law or any agreement to which the Issuers are then
subject.

         (f) If (1) a Shelf Registration is filed pursuant to Section 3 hereof,
or (2) a Prospectus contained in the Exchange Offer Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period relating thereto from whom the Issuers have received
written notice that it will be a Participating Broker-Dealer in the Exchange
Offer as contemplated by Section 2 hereof, furnish to each Holder of Registrable
Notes named as a selling securityholder in the applicable Shelf Registration
Statement, to each such Participating Broker-Dealer who so requests and each
managing underwriter, if any, at the sole expense of the Issuers, one conformed
copy of the Registration Statement or Registration Statements and each post-
effective amendment thereto, including financial statements and schedules, and,
if specifically requested in writing, all documents incorporated or deemed to be
incorporated therein by reference and all exhibits.

         (g) If (1) a Shelf Registration is filed pursuant to Section 3 hereof,
or (2) a Prospectus contained in the Exchange Offer Registration Statement filed
pursuant to Section 2 hereof is


                                      -14-




<PAGE>   16

required to be delivered under the Securities Act by any Participating
Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period
relating thereto from whom the Issuers have received written notice that it will
be a Participating Broker-Dealer in the Exchange Offer as contemplated by
Section 2 hereof, deliver to each selling Holder of Registrable Notes named as a
selling securityholder in the applicable Shelf Registration Statement, or each
such Participating Broker-Dealer, as the case may be, and the managing
underwriters, if any, at the sole expense of the Issuers, as many copies of the
Prospectus or Prospectuses (including each form of preliminary prospectus) and
each amendment or supplement thereto and, if requested in writing, any documents
incorporated by reference therein as such Persons may reasonably request; and,
subject to the last paragraph of this Section 5, the Issuers hereby consent to
the use of such Prospectus and each amendment or supplement thereto (provided
the manner of such use complies with any limitations resulting from any
applicable state securities "Blue Sky" laws as provided in writing to such
Holders by the Issuers and subject to the provisions of this Agreement) by each
of the selling Holders of Registrable Notes or each such Participating
Broker-Dealer, as the case may be, and the underwriters or agents, if any, and
dealers (if any), in connection with the offering and sale of the Registrable
Notes covered by, or the sale by Participating Broker-Dealers of the Exchange
Notes pursuant to, such Prospectus and any amendment or supplement thereto.

         (h) Prior to any public offering of Registrable Notes or any delivery
of a Prospectus contained in the Exchange Offer Registration Statement by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period relating thereto from whom the Issuers have received written
notice that it will be a Participating Broker-Dealer in the Exchange Offer as
contemplated by Section 2 hereof, use its reasonable best efforts to register or
qualify, and to cooperate with the Holders of Registrable Notes named as selling
securityholders in the applicable Shelf Registration Statement or each such
Participating Broker-Dealer, as the case may be, the managing underwriter or
underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Notes for offer and sale under the securities
or Blue Sky laws of such jurisdictions within the United States as any Holder
named as a selling securityholder in the applicable Shelf Registration
Statement, Participating Broker-Dealer, or the managing underwriter or
underwriters reasonably request in writing; provided, that where Exchange Notes
held by Participating Broker-Dealers or Registrable Notes are offered other than
through an underwritten offering, the Issuers agree to, or to cause their
counsel to (i) perform Blue Sky investigations and file registrations and
qualifications required to be filed pursuant to this Section 5(h), (ii) use
their reasonable best efforts to keep each such registration or qualification
(or exemption therefrom) effective during the period such Registration Statement
is required to be kept effective and (iii) do any and all other acts or things
reasonably necessary or advisable to enable the disposition in such
jurisdictions of the Exchange Notes held by Participating Broker-Dealers or the
Registrable Notes covered by the applicable Registration Statement; provided,
that no Issuer shall be required to (A) qualify generally to do business in any
jurisdiction where it is not then so qualified, (B) take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or (C) subject itself to taxation in excess of a nominal
dollar amount in any such jurisdiction where it is not then so subject.

                                      -15-


<PAGE>   17



         (i) If a Shelf Registration is filed pursuant to Section 3 hereof,
cooperate with the selling Holders of Registrable Notes named as selling
securityholders in the applicable Shelf Registration Statement and the managing
underwriter or underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Notes to be sold, which
certificates shall not bear any restrictive legends and shall be in a form
eligible for deposit with The Depository Trust Company; and enable such
Registrable Notes to be in such denominations and registered in such names as
the managing underwriter or underwriters, if any, or selling Holders may
reasonably request.

         (j) If (1) a Shelf Registration is filed pursuant to Section 3 hereof,
or (2) a Prospectus contained in the Exchange Offer Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period relating thereto from whom the Issuers have received
written notice that it will be a Participating Broker-Dealer in the Exchange
Offer as contemplated by Section 2 hereof, upon the occurrence of any event
contemplated by Section 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable
prepare and (subject to Section 3(d) or Section 5(a) hereof) file with the SEC,
at the sole expense of the Issuers, a supplement or post-effective amendment to
the Registration Statement or a supplement to the related Prospectus or any
document incorporated or deemed to be incorporated therein by reference, or file
any other required document so that, as thereafter delivered to the purchasers
of the Registrable Notes being sold thereunder or to the purchasers of the
Exchange Notes to whom such Prospectus will be delivered by a Participating
Broker-Dealer, any such Prospectus will not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

         (k) Prior to the effective date of the first Registration Statement
relating to the Registrable Notes or as soon thereafter as practicable, (i)
provide the Trustee with certificates for the Exchange Notes and Private
Exchange Notes in a form eligible for deposit with The Depository Trust Company
and (ii) provide a CUSIP number for the Exchange Notes and Private Exchange
Notes (which CUSIP number shall, to the extent permissible, be the same as the
CUSIP number for any other notes issued under the Indenture in exchange for
Securities initially issued thereunder).

         (1) In connection with an underwritten offering of Registrable Notes
pursuant to a Shelf Registration and upon the request of the Required Holders,
enter into an underwriting agreement as is customary in underwritten offerings
of debt securities similar to the Registrable Notes in form and substance
reasonably satisfactory to the Issuers and provided that the underwriters are
reasonably acceptable to the Issuers and take all such other actions as are
reasonably requested by the managing underwriter or underwriters in order to
expedite or facilitate the registration or the disposition of such Registrable
Notes and, in such connection, if reasonably requested (i) make such
representations and warranties to, and covenants with, the underwriters with
respect to the business of the Issuers and the subsidiaries of the Issuers
(including any acquired business, properties or entity, if applicable) and the
Registration Statement, Prospectus and documents, if any, incorporated or deemed
to be incorporated by reference therein, in each case, as are





                                      -16-


<PAGE>   18




customarily made by issuers to underwriters in underwritten offerings of debt
securities similar to the Registrable Notes, and confirm the same in writing if
and when reasonably requested in form and substance reasonably satisfactory to
the Issuers; (ii) upon the request of the managing underwriter or Required
Holders, use its reasonable best efforts to obtain the written opinions of
counsel to the Issuers and written updates thereof in form, scope and substance
reasonably satisfactory to the managing underwriter or underwriters, addressed
to the underwriters covering the matters customarily covered in opinions
reasonably requested in underwritten offerings and such other matters as may be
reasonably requested by the managing underwriter or underwriters; (iii) upon the
request of the managing underwriter or Required Holders, use its reasonable best
efforts to obtain "comfort" letters and updates thereof in form, scope and
substance reasonably satisfactory to the managing underwriter or underwriters
from the independent public accountants of the Issuers (and, if necessary, any
other independent public accountants of the Issuers, any subsidiary of the
Issuers or of any business acquired by the Issuers for which financial
statements and financial data are, or are required to be, included or
incorporated by reference in the Registration Statement), addressed to each of
the underwriters, such letters to be in customary form and covering matters of
the type customarily covered in "cold comfort" letters in connection with
underwritten offerings of debt securities similar to the Registrable Notes and
such other matters as reasonably requested by the managing underwriter or
underwriters as permitted by the Statement on Auditing Standards No. 72; and
(iv) if an underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures no less favorable to the sellers and
underwriters, if any, than those set forth in Section 7 hereof (or such other
provisions and procedures acceptable to the managing underwriters, if any, and
the Required Holders). The above shall be done at each closing under such
underwriting agreement, or as and to the extent required thereunder.

         (m) If (1) a Shelf Registration is filed pursuant to Section 3 hereof,
or (2) a Prospectus contained in the Exchange Offer Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period relating thereto from whom the Issuers have received
written notice that it will be a Participating Broker-Dealer in the Exchange
Offer, make available for inspection by any selling Holder of such Registrable
Notes being sold, or each such Participating Broker-Dealer, as the case may be,
any underwriter participating in any such disposition of Registrable Notes, if
any, and any attorney, accountant or other agent retained by any such selling
Holder or each such Participating Broker-Dealer, as the case may be, or
underwriter (collectively, the "Inspectors"), at the offices where normally
kept, during reasonable business hours, all financial and other records,
pertinent corporate documents and instruments of the Issuers and subsidiaries of
the Issuers (collectively, the "Records") as shall be reasonably necessary to
enable them to exercise any applicable due diligence responsibilities, and cause
the officers, directors and employees of the Issuers and any of their
subsidiaries to supply all information reasonably requested by any such
Inspector in connection with such Registration Statement and Prospectus. The
foregoing inspection and information gathering shall be coordinated on behalf of
the other parties by one counsel designated by such parties as described in
Section 6(b) hereof. Each Inspector shall agree in writing that it will keep the
Records confidential and that it will not disclose any of the Records that the
Issuers determine, in good faith, to be confidential unless (i) the release of
such Records is ordered pursuant to a subpoena or

                                      -17-



<PAGE>   19

other order from a court of competent jurisdiction, or (ii) the information in
such Records has been made generally available to the public; provided, that
prior notice shall be provided as soon as practicable to the Issuers of the
potential disclosure of any information by such Inspector pursuant to clause (i)
of this sentence to permit the Issuers to obtain a protective order or take
other appropriate action to prevent the disclosure of such information at the
Issuers' sole expense (or waive the provisions of this paragraph (m)) and that
such Inspector shall take such actions as are reasonably necessary to protect
the confidentiality of such information (if practicable) to the extent such
action is otherwise not inconsistent with, an impairment of or in derogation of
the rights and interests of the Holder or any Inspector.

         (n) Provide an indenture trustee for the Registrable Notes or the
Exchange Notes, as the case may be, and use its reasonable best efforts to cause
the Indenture or the trust indenture provided for in Section 2(a) hereof, as the
case may be, to be qualified under the TIA not later than the effective date of
the first Registration Statement relating to the Registrable Notes; and in
connection therewith, cooperate with the trustee under any such indenture and
the Holders of the Registrable Notes to effect such changes to such indenture as
may be required for such indenture to be so qualified in accordance with the
terms of the TIA; and execute, and use its reasonable best efforts to cause such
trustee to execute, all documents as may be required to effect such changes, and
all other forms and documents required to be filed with the SEC to enable such
indenture to be so qualified in a timely manner.

         (o) Comply with all applicable rules and regulations of the SEC and
make generally available to its securityholders with regard to any applicable
Registration Statement, a consolidated earnings statement, which need not be
audited but that satisfies the provisions of Section 11(a) of the Securities
Act and Rule 158 thereunder (or any similar rule promulgated under the
Securities Act), no later than 60 days after the end of any fiscal quarter (or
120 days after the end of any 12-month period if such period is a fiscal year)
(i) commencing at the end of any fiscal quarter in which Registrable Notes are
sold to underwriters in a firm commitment or reasonable best efforts
underwritten offering and (ii) if not sold to underwriters in such an offering,
commencing on the first day of the first fiscal quarter of the Issuers after the
effective date of a Registration Statement, which statements shall cover said
12-month periods.

         (p) Upon consummation of the Exchange Offer or a Private Exchange,
obtain an opinion of counsel to the Issuers, if requested by the Trustee, in a
form customary for underwritten transactions, addressed to the Trustee for the
benefit of all Holders of Registrable Notes participating in the Exchange Offer
or the Private Exchange, as the case may be, that the Exchange Notes or Private
Exchange Notes, as the case may be, the related Guarantee and the related
indenture constitute legal, valid and binding obligations of the Issuers,
enforceable against them in accordance with their respective terms, subject to
customary exceptions and qualifications.

         (q) If the Exchange Offer or a Private Exchange is to be consummated,
upon delivery of the Registrable Notes by Holders to the Issuers (or to such
other Person as directed by the Issuers) in exchange for the Exchange Notes or
the Private Exchange Notes, as the case may be, the Issuers shall mark, or cause
to be marked, on such Registrable Notes that such Registrable


                                      -18-



<PAGE>   20

Notes are being cancelled in exchange for the Exchange Notes or the Private
Exchange Notes, as the case may be; in no event shall such Registrable Notes be
marked as paid or otherwise satisfied.

         (r) Cooperate with each seller of Registrable Notes covered by any
Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Notes and their respective counsel in connection
with any filings required to be made with the National Association of Securities
Dealers, Inc. (the "NASD").

         (s) Use its reasonable best efforts to cause the Registrable Notes
covered by the Registration Statement to be registered with or approved by such
other governmental agencies or authorities as may be reasonably necessary to
enable the seller or sellers thereof or the underwriter or underwriters, if any,
to consummate the disposition of such Registrable Notes, except as may be
required solely as a consequence of the nature of such selling Holder's
business, in which case the Company will cooperate in all reasonable respects
with the filing of such Registration Statement and the granting of such
approvals.

         (t) Use their reasonable best efforts to take all other steps
reasonably necessary to effect the registration of the Registrable Notes covered
by a Registration Statement contemplated hereby.

         The Issuers may require each seller of Registrable Notes as to which
any registration is being effected to furnish to the Issuers such information
regarding such seller and the distribution of such Registrable Notes as the
Issuers may, from time to time, reasonably request. The Issuers may exclude from
such registration the Registrable Notes of any seller so long as such seller
fails to furnish such information within a reasonable time after receiving such
request. Each seller as to which any Shelf Registration is being effected agrees
to furnish promptly to the Issuers all information required to be disclosed in
order to make the information previously furnished to the Issuers by such seller
not materially misleading.

         Each Holder of Registrable Notes and each Participating Broker-Dealer
agrees by its acquisition of such Registrable Notes or Exchange Notes to be sold
by such Participating Broker Dealer, as the case may be, that, upon actual
receipt of any notice from the Issuers of the happening of any event of the kind
described in Section 5(c)(ii), 5(c)(iv), 5(c)(v) or 5(c)(vi) hereof, such Holder
will forthwith discontinue disposition of such Registrable Notes covered by such
Registration Statement or Prospectus or Exchange Notes to be sold by such Holder
or Participating Broker-Dealer, as the case may be, until such Holder's or
Participating Broker-Dealer's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 5(j) hereof, or until it is advised
in writing (the "Advice") by the Issuers that the use of the applicable
Prospectus may be resumed, and has received copies of any amendments or
supplements thereto. In the event that the Issuers shall give any such notice,

of the giving of such notice to and including the date when each seller of
Registrable Notes covered by such Registration Statement or Exchange Notes to be
sold by such Participating Broker-Dealer, as the case may be, shall have

         7. Indemnification. (a) Each of the Issuers, jointly and severally,
agrees to indemnify and hold harmless each Holder of Registrable Notes and each
Participating Broker-Dealer selling Exchange Notes during the Applicable Period,
the affiliates, officers, directors, representatives, employees and agents of
each such Person, and each Person, if any, who controls any such Person within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each, a "Participant"), from and against any and all losses,
claims, damages, judgments, liabilities and expenses (including, without
limitation, the reasonable legal fees and other expenses actually incurred in
connection with any suit, action or proceeding or any claim asserted) caused by,
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact contained in any Registration Statement (or any amendment
thereto) or Prospectus (as amended or supplemented if the Issuers shall have
furnished any amendments or supplements thereto) or any preliminary prospectus,
or caused by, arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the case of the Prospectus in light of the
circumstances under which they were made, not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any untrue statement or
omission or alleged untrue statement or omission made in reliance upon and in
conformity with information relating to any Participant furnished to the Issuers
in writing by such Participant expressly for use therein and with respect to any
preliminary Prospectus, to the extent that any such loss, claim, damage or
liability arises solely from the fact that any Participant sold Notes to a
person to whom (i) there was not sent or given a copy of the Prospectus (as
amended or supplemented) at or prior to the written confirmation of such sale if
the Issuers shall have previously furnished copies thereof to the Participant in
accordance herewith and the Prospectus (as amended or supplemented) would have
corrected any such untrue statement or omission or (ii) there was delivered a
copy of the Prospectus (as amended or supplemented) after the Holder received
written notice at least one business day prior to the date of delivery of the
Prospectus of any event described in Section 5(c)(ii), 5(c)(iii), 5(c)(iv),
5(c)(v) or 5(c)(vi) and failed to discontinue the delivery of such Prospectus
(as amended or supplemented); provided that with respect to Section 5(c)(iv)
such Holder only needs to discontinue the delivery of such Prospectus (as
amended or supplemented) only in the specific jurisdiction specified in the
notice provided pursuant to Section 5(c)(iv).

         (b) Each Participant agrees, severally and not jointly, to indemnify
and hold harmless the Issuers, their respective affiliates, officers, directors,
representatives, employees and agents of each Issuer and each Person who
controls each Issuer within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent (but on a several, and not
joint, basis) as the foregoing indemnity from the Issuers to each Participant,
but only with reference to information relating to such Participant furnished to
the Issuers in writing by such Participant expressly for use in any Registration
Statement or Prospectus, any amendment or supplement thereto, or any preliminary
prospectus. The liability of any Participant under this paragraph (c) shall in
no event exceed the proceeds received by such Participant from sales of
Registrable Notes or Exchange Notes giving rise to such obligations.

         (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of

                                      -21-




<PAGE>   23

which indemnity may be sought pursuant to either Section 7(a) or 7(b), such
Person (the "Indemnified Person") shall promptly notify the Persons against whom
such indemnity may be sought (the "Indemnifying Persons") in writing, and the
Indemnifying Persons, upon request of the Indemnified Person, shall retain
counsel reasonably satisfactory to the Indemnified Person to represent the
Indemnified Person and any others the Indemnifying Person may reasonably
designate in such proceeding and shall pay the reasonable fees and expenses
actually incurred by such counsel related to such proceeding; provided, that the
failure to so notify the Indemnifying Persons will not relieve it from any
liability under Section 7(a) or 7(b) above unless and to the extent such failure
results in the forfeiture by the Indemnifying Person of substantial rights and
defenses and the Indemnifying Person was not otherwise aware of such action or
claim. In any such proceeding, any Indemnified Person shall have the right to
retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such Indemnified Person unless (i) the Indemnifying Persons and
the Indemnified Person shall have mutually agreed to the contrary, (ii) the
Indemnifying Persons shall have failed within a reasonable period of time to
retain counsel reasonably satisfactory to the Indemnified Person or (iii) the
named parties in any such proceeding (including any impleaded parties) include
both any Indemnifying Person and the Indemnified Person and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
Indemnifying Persons shall not, in connection with such proceeding or separate
but substantially similar related proceeding in the same jurisdiction arising
out of the same general allegations, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Indemnified
Persons, and that all such fees and expenses shall be reimbursed promptly as
they are incurred. Any such separate firm for the Participants and such control
Persons of Participants shall be designated in writing by Participants who sold
a majority in interest of Registrable Notes and Exchange Notes sold by all such
Participants and shall be reasonably acceptable to the Issuers, and any such
separate firm for the Issuers, their affiliates, officers, directors,
representatives, employees and agents and such control Persons of such Issuer
shall be designated in writing by the Issuers and shall be reasonably acceptable
to the Holders.

         The Indemnifying Person shall not be liable for any settlement of any
proceeding effected without its prior written consent (which consent shall not
be unreasonably withheld or delayed), but if settled with such consent or if
there be a final non-appealable judgment for the plaintiff for which the
Indemnified Person is entitled to indemnification pursuant to this Agreement,
each Indemnifying Person agrees to indemnify and hold harmless each Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment. No Indemnifying Person shall, without the prior written consent of the
Indemnified Person (which consent shall not be unreasonably withheld or
delayed), effect any settlement or compromise of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a
party, or indemnity could have been sought hereunder by such Indemnified Person,
unless such settlement (A) includes an unconditional written release of such
Indemnified Person, in form and substance reasonably satisfactory to such
Indemnified Person, from all liability on claims that are the subject matter of
such proceeding and (B) does not include any statement as to an admission of
fault, culpability or failure to act by or on behalf of such Indemnified Person.

         (d) If the indemnification provided for in the Section 7(a) or 7(b) is
for any reason unavailable to, or insufficient to hold harmless, an Indemnified
Person in respect of any losses, claims, damages or liabilities referred to
therein, then each Indemnifying Person under such sections, in lieu of
indemnifying such Indemnified Person thereunder and in order to provide for just
and equitable contribution, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the Indemnifying Person or Persons on the one hand and the Indemnified Person
or Persons on the other in connection with the statements or omissions or
alleged statements or omissions that resulted in such losses, claims, damages
or liabilities (or actions in respect thereof) as well as any other relevant
equitable considerations. The relative fault of the parties shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Issuers on the one hand or
such Participant or such other Indemnified Person, as the case may be, on the
other, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances.

         (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in Section 7(d). The amount paid or payable by an
Indemnified Person as a result of the losses, claims, damages, judgments,
liabilities and expenses referred to in Section 7(d) shall be deemed to include,
subject to the limitations set forth above, any reasonable legal or other
expenses actually incurred by such Indemnified Person in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 7, in no event shall a Participant be required to
contribute any amount in excess of the amount by which proceeds received by such
Participant from sales of Registrable Notes or Exchange Notes, as the case may
be, exceeds the amount of any damages that such Participant has otherwise been
required to pay or has paid by reason of such untrue or alleged untrue statement
or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

         (f) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 7 shall be paid by the Indemnifying Person to the Indemnified Person as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Issuers set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Holder or any person who controls a
Holder, the Issuers, their directors, officers, employees or agents or any
person controlling an Issuer, and (ii) any termination of this Agreement.

         (g) The indemnity and contribution agreements contained in this Section
7 will be in addition to any liability which the Indemnifying Persons may
otherwise have to the Indemnified Persons referred to above.

         8. Rules 144 and 144A. Each of Parent and each Issuer covenants and
agrees that it will use its reasonable best efforts to file the reports required
to be filed by it under the Securities Act and the Exchange Act and the rules
and regulations adopted by the SEC thereunder in a timely manner in accordance
with the requirements of the Securities Act and the Exchange Act. Each of Parent
and each Issuer further covenants and agrees, for so long as any Registrable
Notes remain outstanding, to make available to any Holder or beneficial owner of
Registrable Notes in connection with any sale thereof and any prospective
purchaser of such Registrable Notes from such Holder or beneficial owner the
information required by Rule 144A(d)(4) and 144(c) under the Securities Act in
order to permit resales of such Registrable Notes pursuant to Rule 144A and Rule
144(k).

         9. Underwritten Registrations. If any of the Registrable Notes covered
by any Shelf Registration are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will manage
the offering will be selected by the Required Holders and shall be reasonably
acceptable to the Issuers. The Required Holders shall have the right to require
the Issuers to effect one underwritten offering.

         No Holder of Registrable Notes may participate in any underwritten
registration hereunder unless such Holder (a) agrees to sell such Holder's
Registrable Notes on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

         10. Miscellaneous

         (a) No Inconsistent Agreements. The Issuers have not, as of the date
hereof, and the Issuers shall not, after the date of this Agreement, enter into
any agreement with respect to any of their securities that is inconsistent with
the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with the rights granted to the
holders of the Issuers' other issued and outstanding securities under any such
agreements. The Issuers will not enter into any agreement with respect to any of
their securities which will grant to any Person piggy-back registration rights
with respect to any Registration Statement; provided, that any Securities issued
under the Indenture may be included on a Registration Statement.

         (b) Adjustments Affecting Registrable Notes. The Issuers shall not,
directly or indirectly, take any action with respect to the Registrable Notes as
a class that would adversely affect the ability of the Holders of Registrable
Notes to include such Registrable Notes in a registration undertaken pursuant to
this Agreement.

         (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of (I) the Issuers and (II)(A) the


                                      -24-


<PAGE>   26


Holders of not less than a majority in aggregate principal amount of the then
outstanding Registrable Notes and (B) in circumstances that would adversely
affect the Participating Broker-Dealers, the Participating Broker-Dealers
holding not less than a majority in aggregate principal amount of the Exchange
Notes held by all Participating Broker-Dealers; provided, that Section 7 and
this Section 10(c) may not be amended, modified or supplemented without the
prior written consent of each Holder and each Participating Broker-Dealer
(including any person who was a Holder or Participating Broker-Dealer of
Registrable Notes or Exchange Notes, as the case may be, disposed of pursuant to
any Registration Statement) affected by any such amendment, modification or
supplement. Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders of Registrable Notes whose securities are being sold pursuant
to a Registration Statement and that does not directly or indirectly affect,
impair, limit or compromise the rights of other Holders of Registrable Notes may
be given by Holders of at least a majority in aggregate principal amount of the
Registrable Notes being sold pursuant to such Registration Statement.

         (d) Notices. All notices and other communications (including, without
limitation, any notices or other communications to the Trustee) provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, next-day air courier or facsimile:

               records of the registrar under the Indenture.

               (ii) if to an Issuers, at the address as follows:

                           c/o Orius Corp.

     Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the Trustee at the
address and in the manner specified in such Indenture.

     (e) Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors and assigns of each of the parties hereto,
the Holders and the Participating Broker-Dealers; provided, that nothing herein
shall be deemed to permit any assignment, transfer or other disposition of
Registrable Notes in violation of the terms of the Purchase Agreement or the
Indenture.

     (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

     (g) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

     (h) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE
AND PERFORMED ENTIRELY WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO
THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

     (i) Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected, impaired or invalidated, and the parties hereto shall use
their best efforts to find and employ an alternative means to achieve the same
or substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

     (j) Securities Held by the Issuers or Their Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable Notes is
required hereunder, Registrable Notes held by the Issuers or their affiliates
(as such term is defined in Rule 405 under the Securities Act) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

     (k) Third-Party Beneficiaries. Holders of Registrable Notes and
Participating Broker-Dealers are intended third-party beneficiaries of this
Agreement, and this Agreement may be enforced by such Persons.

     (1) Entire Agreement. This Agreement, together with the Purchase Agreement
and the Indenture, is intended by the parties as a final and exclusive statement
of the agreement and understanding of the parties hereto in respect of the
subject matter contained herein and therein and any and all prior oral or
written agreements, representations, or warranties, contracts, understandings,
correspondence, conversations and memoranda between the Holders on the one hand
and the Issuers on the other, or between or among any agents, representatives,

         the Initial Borrowing Date, (ii) shall be denominated in Dollars, (iii)
         shall be made as Base Rate Loans and, except as hereinafter provided,
         may, at the option of Borrowers, be maintained as and/or converted into
         Base Rate Loans or Eurodollar Loans, provided, that all Term B Loans
         made by the Term B Lenders pursuant to the same Borrowing shall, unless
         otherwise specifically provided herein, consist entirely of Term B
         Loans of the same Type and (iv) shall not exceed for any Lender at the
         time of incurrence thereof on the Initial Borrowing Date that aggregate
         principal amount which equals the Term B Commitment, if any, of such
         Lender at such time. No amount of a Term B Loan which is repaid or
         prepaid by Borrower may be reborrowed hereunder.

                  (b) Revolving Loans.

                  (i) Working Capital Loans and Acquisition Revolving Loans.
         Each Revolving Lender, severally and for itself alone, hereby agrees,
         on the terms and subject to the conditions hereinafter set forth and in
         reliance upon the representations and warranties set forth herein and
         in the other Loan Documents, to make loans to Borrowers (on a joint and
         several basis) on a revolving basis from time to time during the
         Commitment Period (provided that Acquisition Revolving Loans may only
         be made during the Acquisition Commitment Period), in an amount not to
         exceed its Revolver Pro Rata Share of the Total Available Revolving
         Commitment (each such loan by any Lender, a "Revolving Loan" and
         collectively, the "Revolving Loans"). The Revolving Loans (i) shall be
         denominated in Dollars and (ii) if made on the Initial Borrowing Date
         (or any date, in the case of Acquisition Revolving Loans), shall be
         made as Base Rate Loans and, except as hereinafter provided, may, at
         the option of Borrowers, be maintained as and/or converted into Base
         Rate Loans or Eurodollar Loans. All Revolving Loans comprising the same
         Borrowing hereunder shall be made by the Revolving Lenders
         simultaneously and in proportion to their respective Revolving
         Commitments. Prior to the Revolver Termination Date, Working Capital
         Loans may be repaid and reborrowed by Borrowers in accordance with the
         provisions hereof. Prior to the last day of the Acquisition Commitment
         Period, Acquisition Revolving Loans may be repaid and reborrowed by
         Borrowers in accordance with the provisions hereof. Except as otherwise
         specifically provided herein, all Revolving Loans comprising the same
         Borrowing shall at all times be of the same Type.

                  (ii) Sublimit Amounts. Revolving Loans may not be incurred as
         Acquisition Revolving Loans if after giving effect thereto the
         aggregate outstanding principal amount of Acquisition Revolving Loans
         would exceed the Acquisition Revolving Sublimit at such time. Revolving
         Loans may not be incurred as Working Capital Loans if after giving
         effect thereto the aggregate outstanding principal amount of Working
         Capital Loans would exceed the Working Capital Sublimit at such time.

                  (iii) Conversion of Acquisition Revolving Loans. Subject to
         and upon the terms and conditions set forth herein, Borrowers and each
         Lender agree that, at 9:00 A.M. (New York City time) on the Acquisition
         Revolver Conversion Date, the aggregate principal amount of Acquisition
         Revolving Loans owing to each Revolving Lender and outstanding at such
         time shall (unless such Acquisition Revolving Loans have been declared
         (or have become) due and payable pursuant to this Agreement), without
         any notice or action by any party hereto, automatically convert to and
         thereafter constitute term loans (each such Loan by any Revolving
         Lender, an "Acquisition Term Loan" and collectively the "Acquisition
         Term Loans" and together with the Acquisition Revolving Loans, the
         "Acquisition Loans") owing to such Lenders hereunder. The Acquisition
         Term Loans shall (i) subject to the provisions of Section 2.3,
         initially be continued as one or more Borrowing of Base Rate Loans or
         Eurodollar Loans in accordance with the designation of such Borrowings
         immediately prior to giving effect to such conversion, with any
         Interest Periods applicable thereto to continue in effect until the
         expiration thereof, provided that, all Acquisition Term Loans
         comprising the same Borrowing shall at all times be of the same Type
         and (ii) not exceed an initial principal amount for any Lender that
         amount which equals the aggregate principal amount of Acquisition
         Revolving Loans owed to such Lender and outstanding immediately prior
         to such conversion. Once repaid, Acquisition Term Loans may not be
         reborrowed.

                  (c) Swing Line Loans.

                  (i) Swing Line Commitment. Subject to the terms and conditions
         hereof, the Swing Line Lender in its individual capacity agrees to make
         swing line loans in Dollars ("Swing Line Loans") to Borrowers (on a
         joint and several basis) on any Business Day from time to time during
         the Commitment Period in an aggregate principal amount at any one time
         outstanding not to exceed $2,500,000; provided, however, that in no
         event may the amount of any Borrowing of Swing Line Loans (A) exceed
         the Total Available Revolving Commitment immediately prior to such
         Borrowing (after giving effect to the use of proceeds thereof), (B)
         cause the outstanding Acquisition Revolving Loans and Working Capital
         Loans of any Revolving Lender, when added to such Lender's Revolver Pro
         Rata Share of the then outstanding Swing Line Loans and Revolver Pro
         Rata Share of the aggregate LC Obligations (exclusive of Unpaid
         Drawings relating to LC Obligations which are repaid with the proceeds
         of, and simultaneously with the incurrence of, Working Capital Loans or
         Swing Line Loans) to exceed such Lender's Revolving Commitment or (C)
         cause the outstanding Working Capital Loans of all Revolving Lenders,
         when added to the then outstanding Swing Line Loans and the aggregate
         LC Obligations (exclusive of Unpaid Drawings relating to LC Obligations
         which are repaid with the proceeds of, and simultaneously with the
         incurrence of, Working Capital Loans or Swing Line Loans) to exceed the
         Working Capital Sublimit. Amounts borrowed by Borrowers under this
         Section 2.1(c)(i) may be repaid and reborrowed during the period from
         the Closing Date to but excluding five (5) Business Days prior to the
         Revolver Termination Date. The Swing Line Loans shall be made in
         Dollars and maintained as Base Rate Loans and, notwithstanding Section
         2.6, shall not be entitled to be converted into any other Type of Loan.

                                       43
<PAGE>   45

                  (ii) Refunding of Swing Line Loans. The Swing Line Lender, at
         any time in its sole and absolute discretion, may on behalf of
         Borrowers (which hereby irrevocably direct the Swing Line Lender to so
         act on their behalf) notify each Revolving Lender (including the Swing
         Line Lender) to make a Working Capital Loan in an amount equal to such
         Lender's Revolver Pro Rata Share of the principal amount of the Swing
         Line Loans (the "Refunded Swing Line Loans") outstanding on the date
         such notice is given, provided, however, that such notice shall be
         deemed to have automatically been given upon the occurrence of an Event
         of Default under Sections 10.1(e) or 10.1(f) or upon the occurrence of
         a Change of Control. Unless any of the events described in Sections
         10.1(e) or 10.1(f) shall have occurred (in which event the procedures
         of Section 2.1(c)(iii) shall apply) and regardless of whether the
         conditions precedent set forth in this Agreement to the making of a
         Working Capital Loan are then satisfied, each Revolving Lender shall
         make the proceeds of its Working Capital Loan available to the Swing
         Line Lender at the Payment Office prior to 11:00 A.M., New York City
         time, in funds immediately available on the Business Day next
         succeeding the date such notice is given. The proceeds of such Working
         Capital Loans shall be immediately applied to repay the Refunded Swing
         Line Loans.

                  (iii) Participation in Swing Line Loans. If, prior to
         refunding a Swing Line Loan with a Revolving Loan pursuant to Section
         2.1(c)(ii), one of the events described in Sections 10.1(e) or 10.1(f)
         shall have occurred, or if for any other reason a Working Capital Loan
         cannot be made pursuant to Section 2.1(c)(ii), then, subject to the
         provisions of Section 2.1(c)(iv) below, each Revolving Lender will, on
         the date such Working Capital Loan was to have been made, purchase
         (without recourse or warranty) from the Swing Line Lender an undivided
         participation interest in the Swing Line Loan in an amount equal to its
         Revolver Pro Rata Share of such Swing Line Loan. Upon request, each
         Revolving Lender will immediately transfer to the Swing Line Lender, in
         immediately available funds, the amount of its participation and upon
         receipt thereof the Swing Line Lender will deliver to such Lender a
         Swing Line Loan Participation Certificate dated the date of receipt of
         such funds and in such amount.

                  (iv) Lenders' Obligations Unconditional. Each Revolving
         Lender's obligation to make Working Capital Loans in accordance with
         Section 2.1(c)(ii) and to purchase participating interests in
         accordance with Section 2.1(c)(iii) above shall be absolute and
         unconditional and shall not be affected by any circumstance, including,
         without limitation, (A) any set-off, counterclaim, recoupment, defense
         or other right which such Lender may have against the Swing Line
         Lender, any Borrower or any other Person for any reason whatsoever; (B)
         the occurrence or continuance of any Event of Default or Unmatured
         Event of Default; (C) any adverse change in the condition (financial or
         otherwise) of any Borrower or any other Person; (D) any breach of this
         Agreement by any Borrower or any other Person; (E) any inability of any
         Borrower to satisfy the conditions precedent to borrowing set forth in
         this Agreement on the date upon which such participating interest is to
         be purchased or (F) any other circumstance, happening or event
         whatsoever, whether or not similar to any of the foregoing. If any
         Revolving Lender does not make available to the Swing Line Lender the
         amount required pursuant to Section 2.1(c)(ii) or (iii) above, as the
         case may be, the Swing Line Lender shall be entitled to recover such
         amount on demand from such Lender, together with interest

                                       44
<PAGE>   46

         thereon for each day from the date of non-payment until such amount is
         paid in full at the Federal Funds Rate for the first two Business Days
         and at the Base Rate thereafter. Notwithstanding the foregoing
         provisions of this Section 2.1(c)(iv), no Lender shall be required to
         make a Working Capital Loan to Borrower for the purpose of refunding a
         Swing Line Loan pursuant to Section 2.1(c)(ii) above or to purchase a
         participating interest in a Swing Line Loan pursuant to Section
         2.1(c)(iii) if an Event of Default or Unmatured Event of Default has
         occurred and is continuing and, prior to the making by the Swing Line
         Lender of such Swing Line Loan, the Swing Line Lender has received
         written notice from such Lender specifying that such Event of Default
         or Unmatured Event of Default has occurred and is continuing,
         describing the nature thereof and stating that, as a result thereof,
         such Lender shall cease to make such Refunded Swing Line Loans and
         purchase such participating interests, as the case may be; provided,
         however, that the obligation of such Lender to make such Refunded Swing
         Line Loans and to purchase such participating interests shall be
         reinstated upon the earlier to occur of (y) the date upon which such
         Lender notifies the Swing Line Lender that its prior notice has been
         withdrawn and (z) the date upon which the Event of Default or Unmatured
         Event of Default specified in such notice no longer is continuing.

                  Section 2.3. Minimum Amount of Each Borrowing; Maximum Number

Borrowing Date pursuant to Section

                                       46
<PAGE>   48

2.1(a)(i) and after the Initial Borrowing Date pursuant to Section 2.9(c)(ii),
the aggregate principal amount of each Borrowing by Borrowers hereunder shall be
not less than (i) in the case of a Base Rate Loan, $1,000,000 and, if greater,
shall be in integral multiples of $500,000 above such minimum (or, if less, the

Loan, $1,000,000 and, if greater, shall be in integral multiples of $500,000
above such minimum and (iii) in the case of a Swing Line Loan, $250,000 and, if

earlier to occur of (a) the 90th day after the Initial Borrowing Date and (b)
the date on which Agent determines in its sole discretion that the primary
syndication of the Loans has been completed (with Agent agreeing to promptly
notify Borrowers of such determination) (the "Syndication Period"), no Loan may
be made or converted, into a Eurodollar Loan with an Interest Period in excess
of 14 days (with all such Interest Periods ending on the same day during such
period). As to any Eurodollar Loan, any Lender may, if it so elects, fulfill its
commitment by causing a foreign branch or affiliate to make or continue such
Loan, provided that in such event that Lender's Loan shall, for the purposes of
this Agreement, be considered to have been made by that Lender and the
obligation of Borrowers to repay such Loan shall nevertheless be to that Lender
and shall be deemed held by that Lender, for the account of such branch or
affiliate.

                  Section 2.5. Notice of Borrowing. Whenever a Borrower desires
to make a Borrowing of any Loan hereunder, it shall give Agent at its office
located at One Bankers Trust Plaza, 130 Liberty Street, New York, New York 10006
(or such other address as the Agent may hereafter designate in writing to the
parties hereto) (the "Notice Address") at least one Business Day's prior written
notice (or telephonic notice promptly confirmed in writing), given not later
than 12:00 P.M. (New York City time) of each Base Rate Loan, and at least three
Business Days' prior written notice (or telephonic notice promptly confirmed in
writing), given not later than 12:00 P.M. (New York City time), of each
Eurodollar Loan to be made hereunder; provided, however, that a Notice of
Borrowing with respect to Borrowings to be made on the date hereof may, at the
discretion of Agent, be delivered later than the time specified above. Whenever
a Borrower desires that Swing Line Lender make a Swing Line Loan under Section
2.1(c), it shall deliver to Swing Line Lender prior to 12:00 P.M. (New York City
time) on the date of Borrowing written notice (or telephonic notice promptly
confirmed in writing). Each such notice (each a "Notice of Borrowing"), which
shall be in the form of Exhibit 2.5 hereto, shall be deemed a representation by
Borrowers that all conditions precedent to such Borrowing have been satisfied
and shall specify (i) the aggregate principal amount of the Loans to be made
pursuant to such Borrowing, (ii) the date of Borrowing (which shall be a
Business Day), (iii) whether the Revolving Loans being made pursuant to such
Borrowing are Working Capital Loans or Acquisition Revolving Loans and (iv)
whether the Loans being made pursuant to such

                                       47
<PAGE>   49

Borrowing are to be Base Rate Loans or Eurodollar Loans and, with respect to
Eurodollar Loans, the Interest Period to be applicable thereto. Agent shall as
promptly as practicable give each Lender written or telephonic notice (promptly
confirmed in writing) of each proposed Borrowing, of such Lender's Revolver Pro
Rata Share, Term A Pro Rata Share or Term B Pro Rata Share, as applicable,
thereof and of the other matters covered by the Notice of Borrowing. Without in
any way limiting Borrowers' obligation to confirm in writing any telephonic
notice, Agent or the Swing Line Lender (in the case of Swing Line Loans) or the
respective Facing Agent (in the case of Letters of Credit) may act without
liability upon the basis of telephonic notice believed by Agent in good faith
and in the absence of gross negligence or willful misconduct to be from a
Responsible Officer of a Borrower prior to receipt of written confirmation.
Agent's records shall, absent manifest error, be final, conclusive and binding
on Borrowers with respect to evidence of the terms of such telephonic Notice of
Borrowing.

                  Section 2.6. Conversion or Continuation. Subject to Section
2.4, any Borrower may elect (i) on any Business Day to convert Base Rate Loans
or any portion thereof to Eurodollar Loans and (ii) at the end of any Interest
Period with respect thereto, to convert Eurodollar Loans or any portion thereof
into Base Rate Loans or to continue such Eurodollar Loans or any portion thereof
for an additional Interest Period; provided, however, that the aggregate
principal amount of the Eurodollar Loans for each Interest Period therefor must
be in an aggregate principal amount of $1,000,000 or an integral multiple of
$500,000 in excess thereof. Each such election shall be in substantially the
form of Exhibit 2.6 hereto (a "Notice of Conversion or Continuation") and shall
be made by giving Agent at least three Business Days' prior written notice
thereof, given not later than 12:00 P.M. (New York City time), to the Notice
Address specifying (i) the amount and type of conversion or continuation, (ii)
in the case of a conversion to or a continuation of Eurodollar Loans, the
Interest Period therefor, (iii) whether such conversion or continuation is made
with respect to Acquisition Loans, Working Capital Loans, Term A Loans or Term B
Loans and (iv) in the case of a conversion, the date of conversion (which date
shall be a Business Day and, if a conversion from Eurodollar Loans, shall also
be the last day of the Interest Period therefor). Notwithstanding the foregoing,
no conversion in whole or in part of Base Rate Loans to Eurodollar Loans, and no
continuation in whole or in part of Eurodollar Loans upon the expiration of any
Interest Period therefor, shall be permitted at any time at which an Unmatured
Event of Default or an Event of Default shall have occurred and be continuing.
If, within the time period required under the terms of this Section 2.6, Agent
does not receive a Notice of Conversion or Continuation from a Borrower
containing a permitted election to continue any Eurodollar Loans for an
additional Interest Period or to convert any such Loans, then, upon the
expiration of the Interest Period therefor, such Loans will be automatically
converted to Base Rate Loans. Each Notice of Conversion or Continuation shall be
irrevocable.

                  Section 2.7. Disbursement of Funds. No later than 12:00 P.M.
(New York City time) on the date specified in each Notice of Borrowing, each
Lender will make available its Term A Pro Rata Share of Term A Loans, Term B Pro
Rata Share of Term B Loans and Revolver Pro Rata Share of Revolving Loans of the
Borrowing requested to be made on such date in Dollars and in immediately
available funds, at the office (the "Payment Office") of Agent located at One
Bankers Trust Plaza, 130 Liberty Street, 14th Floor New York, New York 10006
Attention: Commercial Loan Division (for the account of such non-U.S. office of
Agent as Agent may direct in the case of Eurodollar Loans) and Agent will make
available to Borrowers at




                                       48

its Payment Office the aggregate of the amounts so made available by the
Lenders. Unless Agent shall have been notified by any Lender at least one
Business Day prior to the date of Borrowing that such Lender does not intend to
make available to Agent such Lender's portion of the Borrowing to be made on
such date, Agent may assume that such Lender has made such amount available to
Agent on such date of Borrowing and Agent may, but shall not be required to, in
reliance upon such assumption, make available to Borrower a corresponding
amount. If such corresponding amount is not in fact made available to Agent by
such Lender on the date of Borrowing, Agent shall be entitled to recover such
corresponding amount on demand from such Lender. If such Lender does not pay
such corresponding amount forthwith upon Agent's demand therefor, Agent shall
promptly notify Borrowers and, if so notified, Borrowers shall immediately pay
such corresponding amount to Agent. Agent shall also be entitled to recover from
Borrowers interest on such corresponding amount in respect of each day from the
date such corresponding amount was made available by Agent to Borrowers to the
date such corresponding amount is recovered by Agent, at a rate per annum equal
to the rate for Base Rate Loans or Eurodollar Loans, as the case may be,
applicable during the period in question, provided, however, that any interest
paid to Agent in respect of such corresponding amount shall be credited against
interest payable by Borrowers to such Lender under Section 3.1 in respect of
such corresponding amount. Any amount due hereunder to Agent from any Lender
which is not paid when due shall bear interest payable by such Lender, from the
date due until the date paid, at the Federal Funds Rate for the first three days
after the date such amount is due and thereafter at the Federal Funds Rate plus
1%, together with Agent's standard interbank processing fee. Further, such
Lender shall be deemed to have assigned any and all payments made of principal
and interest on its Loans, amounts due with respect to its Letters of Credit (or
its participations therein) and any other amounts due to it hereunder first to
Agent to fund any outstanding Loans made available on behalf of such Lender by
Agent pursuant to this Section 2.7 until such Loans have been funded (as a
result of such assignment or otherwise) and then to fund Loans of all Lenders
other than such Lender until each Lender has outstanding Loans equal to its Term
A Pro Rata Share of all Term A Loans, its Term B Pro Rata Share for all Term B
Loans and its Revolver Pro Rata Share of all Revolving Loans (as a result of
such assignment or otherwise). Such Lender shall not have recourse against any
Borrower with respect to any amounts paid to Agent or any Lender with respect to
the preceding sentence; provided, that such Lender shall have full recourse
against Borrowers to the extent of the amount of such Loans it has so been
deemed to have made. Nothing herein shall be deemed to relieve any Lender from
its obligation to fulfill its Commitment hereunder or to prejudice any rights
which Borrowers may have against the Lender as a result of any default by such
Lender hereunder.

                  Section 2.8. Pro Rata Borrowings. All Borrowings of Term A
Loans, Term B Loans and Revolving Loans under this Agreement shall be loaned by
the Lenders pro rata on the basis of their Term A Commitments, Term B
Commitments or Revolving Commitments, as the case may be. No Lender shall be
responsible for any default by any other Lender in its obligation to make Loans
hereunder and each Lender shall be obligated to make the Loans provided to be
made by it hereunder, regardless of the failure of any other Lender to fulfill
its Commitments hereunder.

                  Section 2.9. Letter of Credit.

                  (a)   Letter of Credit Commitments.

                  (i)   Subject to and upon the terms and conditions herein set
         forth and such other conditions as are applicable to its customers
         generally, BT agrees to issue, or cause one of its Affiliates
         (including without limitation Deutsche Bank AG, New York Branch), to
         issue in its own name (in such capacity, "Facing Agent"), but for the
         ratable benefit of all Term A Lenders (including Facing Agent) in the
         case of Rollover Letters of Credit and for the ratable benefit of all
         Revolving Lenders (including the Facing Agent) in the case of all
         Letters of Credit other than Rollover Letters of Credit (A) on the
         Initial Borrowing Date, the Rollover Letters of Credit, and (B) at any
         time and from time to time on or after the Initial Borrowing Date and
         prior to the 30th day preceding the Revolver Termination Date, one or
         more Letters of Credit (other than a Rollover Letter of Credit), each
         having a Stated Amount in Dollars and each being issued at sight, for
         the account of a Borrower in an aggregate undrawn amount at any one
         time outstanding that together with the aggregate Stated Amount of
         other Letters of Credit then outstanding (other than the Rollover
         Letters of Credit), does not exceed $15,000,000; provided, however,
         that Facing Agent shall not issue or extend the expiration of any
         Letter of Credit if, immediately after giving effect to such issuance
         or extension, (A) the aggregate LC Obligations at such time would
         exceed $15,000,000, (B) the Available Revolving Commitment of any
         Revolving Lender would be less than zero or (C) the outstanding Working
         Capital Loans of all Revolving Lenders, when added to the then
         outstanding Swing Line Loans and the aggregate LC Obligations, would
         exceed the Working Capital Sublimit. Each Revolving Lender severally,
         but not jointly, agrees to participate in each such Letter of Credit
         (other than a Rollover Letter of Credit) issued by Facing Agent to the
         extent of its Revolver Pro Rata Share and to make available to Facing
         Agent such Lender's Revolver Pro Rata Share of any payment made to the
         beneficiary of such Letter of Credit to the extent not reimbursed by
         Borrowers pursuant to Section 2.9(c)(i); provided, however, that no
         Revolving Lender shall be required to participate in any such Letter of
         Credit to the extent that such participation therein would exceed such
         Lender's Available Revolving Commitment then in effect. Each Term A
         Lender severally, but not jointly agrees to participate in each
         Rollover Letter of Credit issued by Facing Agent to the extent of its
         Term A Pro Rata Share and to make available to Facing Agent such
         Lender's Term A Pro Rata Share of any payment made to the beneficiary
         of such Rollover Letter of Credit pursuant to Section 2.9(c)(ii);
         provided, however, that no Term A Lender shall be required to
         participate in any Rollover Letter of Credit to the extent that such
         participation therein would exceed such Lender's Available Term A
         Commitment then in effect. No Lender's obligation to participate in any
         Letter of Credit or to make available to Facing Agent such Lender's
         Revolver Pro Rata Share or Term A Pro Rata Share as applicable of any
         Letter of Credit Payment made by Facing Agent shall be affected by any
         other Lender's failure to participate in the same or any other Letter
         of Credit or by any other Lender's failure to make available to Facing
         Agent such other Lender's Revolver Pro Rata Share or Term A Pro Rata
         Share as applicable of any Letter of Credit Payment. Notwithstanding
         the foregoing, in the event a Lender Default exists, Facing Agent shall
         not be required to issue any Letter of Credit unless Facing Agent has
         entered into arrangements satisfactory to it and Borrowers to eliminate
         such Facing


                                       50

<PAGE>   52

         Agent's risk with respect to the participation in Letters of Credit of
         the Defaulting Lender or Lenders, including by cash collateralizing
         such Defaulting Lender's or Lenders' Revolver Pro Rata Share or Term A
         Pro Rata Share as applicable of the LC Obligations.

                  (ii)  Each Standby Letter of Credit issued or to be issued
         hereunder shall have an expiration date of one (1) year or less from
         the issuance date thereof and each Commercial Letter of Credit issued
         or to be issued hereunder shall have an expiration date of one hundred
         eighty (180) days or less from the issuance date hereof; provided,
         however, that each Standby Letter of Credit may provide by its terms
         that it will be automatically extended for additional successive
         periods of up to one (1) year unless Facing Agent shall have given
         notice to the applicable beneficiary of the election by Facing Agent
         (such election to be in the sole and absolute discretion of Facing
         Agent) not to extend such Letter of Credit; provided, further, that no
         Standby Letter of Credit or extension thereof shall be stated to expire
         later than the 10th Business Day preceding the Revolver Termination
         Date, no Rollover Letter of Credit or extension thereof shall be stated
         to expire later than the Rollover LC Termination Date and no Commercial
         Letter of Credit or extension thereof shall be stated to expire later
         than the day thirty (30) days prior to the Revolver Termination Date.

                  (b)   Procedure for Issuance of Letters of Credit. Whenever a
Borrower desires the issuance of a Letter of Credit hereunder, it shall give
Agent and Facing Agent at least three (3) Business Days' prior written notice
(or such shorter period as may be agreed to by such Borrower, Agent and Facing
Agent) specifying the day of issuance thereof (which day shall be a Business
Day), such notice to be given prior to 12:00 P.M. (New York City time) on the
date specified for the giving of such notice. Each such notice (each, a "Letter
of Credit Request") shall be in the form of Exhibit 2.9 hereto and shall specify
(A) the proposed issuance date and expiration date, (B) the name(s) of each
obligor with respect to such Letter of Credit, (C) a Borrower as the account
party, (D) the name and address of the beneficiary (which Person shall be
reasonably acceptable to Facing Agent), (E) the Stated Amount of such proposed
Letter of Credit and (F) the purpose of such Letter of Credit and such other
information as Facing Agent may reasonably request (which shall be acceptable to
Agent and Facing Agent). In addition, each Letter of Credit Request shall
contain a description of the terms and conditions to be included in such
proposed Letter of Credit (all of which terms and conditions shall be acceptable
to Facing Agent). Promptly after the issuance or amendment of any Letter of
Credit, Facing Agent shall notify Agent and the applicable Borrower of such
issuance or amendment, and such notice shall be accompanied by a copy of such
issuance or amendment. Promptly after receipt of such notice, Agent shall notify
the Lenders of such issuance or amendment and shall provide a copy thereof upon
the request of any Lender. Unless otherwise specified, all Letters of Credit
will be governed by the Uniform Customs and Practice for Documentary Credits as
in effect on the date of issuance of such Letter of Credit. Each Letter of
Credit shall include any other documents as Facing Agent customarily requires in
connection therewith. On the Business Day specified by a Borrower and upon
fulfillment or waiver of the applicable conditions set forth in Article V,
Facing Agent will issue the requested Letter of Credit to the applicable
beneficiary.

                  (c)    Draws upon Letters of Credit; Reimbursement Obligation.

                  (i)    In the event of any drawing under any Letter of Credit
         (other than a Rollover Letter of Credit) by the beneficiary thereof,
         Facing Agent shall give written notice to the applicable Borrower and
         Agent (x) confirming such drawing and (y) of the date on or before
         which Facing Agent intends to honor such drawing, and Borrowers shall
         reimburse Facing Agent on the day on which such drawing is honored in
         an amount in same day funds and like currency equal to the amount of
         such drawing; provided, however, that, anything contained in this
         Agreement to the contrary notwithstanding, (A) unless Borrowers shall
         have notified Agent and Facing Agent prior to 11:00 A.M. (New York City
         time) on the Business Day Facing Agent intends to honor such drawing
         that Borrowers intend to reimburse Facing Agent for the amount of such
         drawing with funds other than the proceeds of Working Capital Loans,
         Borrowers shall be deemed to have timely given a Notice of Borrowing to
         Agent requesting each Revolving Lender to make Working Capital Loans
         which are Base Rate Loans on the date on which such drawing is honored
         in an amount equal to the amount of such drawing and (B) unless any of
         the events described in Section 10.1(e) or 10.1(f) shall have occurred
         (in which event the procedures of Section 2.9(d) shall apply) each such
         Lender shall, on the date of such drawing, make Working Capital Loans
         which are Base Rate Loans in the amount of its Revolver Pro Rata Share
         of such drawing, the proceeds of which shall be applied directly by
         Agent to reimburse Facing Agent for the amount of such drawing;
         provided, further, that, if for any reason, proceeds of Working Capital
         Loans are not received by Facing Agent on such date in an amount equal
         to the amount of such drawing, Borrowers shall reimburse Facing Agent,
         on the Business Day immediately following the date of such drawing, in
         an amount in same day funds equal to the excess of the amount of such
         drawing over the amount of such Working Capital Loans, if any, which
         are so received, plus accrued interest on such amount at the rate set
         forth in Section 3.1(a).

                  (ii)  In the event of any drawing under any Rollover Letter of
         Credit by the beneficiary thereof, Facing Agent shall give written
         notice to the applicable Borrower and Agent (which notice Agent shall
         promptly transmit to the Term A Lenders) confirming such drawing and of
         the date on or before which Facing Agent intends to honor such drawing.
         Borrowers shall be deemed to have timely given a Notice of Borrowing to
         Agent requesting each Term A Lender to make Term A Loans which are Base
         Rate Loans on the date on which such drawing is honored in an amount
         equal to the amount of such drawing and unless any of the events
         described in Section 10.1(e) or 10.1(f) shall have occurred (in which
         event the procedures of Section 2.9(d) shall apply) each Term A Lender
         shall, on the date of such drawing, make Term A Loans which are Base
         Rate Loans in the amount of its Term A Pro Rata Share of such drawing,
         the proceeds of which shall be applied directly by Agent to reimburse
         Facing Agent for the amount of such drawing; provided, further, that,
         if for any reason, proceeds of Term A Loans are not received by Facing
         Agent on such date in an amount equal to the amount of such drawing,
         Borrowers shall reimburse Facing Agent, on the Business Day immediately
         following the date of such drawing, in an amount in same day funds
         equal to the excess of the amount of such drawing over the amount of
         such Term A Loans, if any, which are so received, plus accrued interest
         on such amount at the rate set forth in Section 3.1(a).

                  (d)   Lenders' Participation in Letters of Credit. In the
event that Borrowers shall fail to reimburse Facing Agent as provided in Section
2.9(c) in an amount equal to the amount of any drawing honored by Facing Agent
under a Letter of Credit issued by it in accordance with the terms hereof,
Facing Agent shall promptly notify Agent and Agent shall promptly notify each
Lender of the unreimbursed amount of such drawing and of such Lender's
respective participation therein. Each such Lender shall make available to
Facing Agent an amount equal to its Revolver Pro Rata Share or Term A Pro Rata
Share, as applicable, of such drawing in same day funds, at the office of Facing
Agent specified in such notice, not later than 1:00 P.M. (New York City time) on
the Business Day after the date such Lender is notified by Agent. In the event
that any such Lender fails to make available to Facing Agent the amount of such
Lender's participation in such Letter of Credit as provided in this Section
2.9(d), Facing Agent shall be entitled to recover such amount on demand from
such Lender together with interest at the Federal Funds Rate for two Business
Days and thereafter at the Base Rate. Nothing in this Section 2.9(d) shall be
deemed to prejudice the right of any Lender to recover from Facing Agent any
amounts made available by such Lender to Facing Agent pursuant to this Section
2.9(d) in the event that it is determined that the payment with respect to a
Letter of Credit by Facing Agent in respect of which payment was made by such
Lender constituted gross negligence or willful misconduct as determined by a
court of competent jurisdiction on the part of Facing Agent. Facing Agent shall
distribute to each other Lender which has paid all amounts payable by it under
this Section 2.9(d) with respect to any Letter of Credit issued by Facing Agent
such other Lender's Revolver Pro Rata Share or Term A Pro Rata Share, as
applicable, of all payments received by Facing Agent from Borrowers in
reimbursement of drawings honored by Facing Agent under such Letter of Credit
when such payments are received. Upon any change in the Revolving Commitments or
Term A Commitments of the Lenders pursuant to Section 3.7 or 12.8(c) or
otherwise, it is hereby agreed that, with respect to all LC Obligations, there
shall be an automatic adjustment to the participations pursuant to this Section
2.9(d) to reflect the new Revolver Pro Rata Shares of the assigning Lender and
the Assignee and with respect to all Rollover LC Obligations, there shall be an
automatic adjustment to the participations pursuant to this Section 2.9(d) to
reflect the new Term A Pro Rata Shares of the assigning Lender and the Assignee.

                  (e)   Fees for Letters of Credit.

                  (i)   Facing Agent Fees. Borrowers agree jointly and severally
         to pay the following amounts to Facing Agent with respect to Letters of
         Credit issued by it for the account of any Borrower:

                  (A)   with respect to drawings honored under any Letter of
         Credit, interest, payable on demand, at a rate which is at all times
         equal to 2% per annum in excess of the Base Rate on the amount paid by
         Facing Agent in respect of each such drawing from the date the drawing
         is honored (unless such drawing occurs after 4:00 p.m. (New York City
         time) in which case from the day following such drawing) to the date
         such amount is reimbursed by Borrowers (including any such
         reimbursement out of the proceeds of Revolving Loans or Term A Loans,
         as applicable, pursuant to Section 2.9(c));

                  (B)   with respect to the issuance or amendment of each Letter
         of Credit and each payment made thereunder, documentary and processing
         charges in accordance with


                                       53

<PAGE>   55


         Facing Agent's standard schedule for such charges in effect at the time
         of such issuance, amendment, transfer or payment, as the case may be;
         and

                  (C)   a facing fee equal to 0.25% per annum of the outstanding
         LC Obligations and Rollover LC Obligations payable with respect to the
         maximum Stated Amount under such outstanding Letters of Credit payable
         in arrears on each Quarterly Payment Date, on the Revolver Termination
         Date and thereafter, on demand together with customary issuance and
         drawing charges payable pursuant to clause (B) above; provided,
         however, if calculation of the facing fee in the manner set forth above
         would result in a facing fee of less than $500 per year per Letter of
         Credit, Borrower shall be obligated to pay such additional amount to
         the Facing Agent so as to provide for a minimum facing fee of $500 per
         year per Letter of Credit.

                  (ii)  Participating Lender Fees.

                  (A)   Borrowers agree jointly and severally to pay to Agent
         for distribution to each participating Lender that is not a Defaulting
         Lender in respect of all Letters of Credit (other than Rollover Letters
         of Credit) outstanding such Lender's Revolver Pro Rata Share of a per
         annum commission equal to the Applicable Eurodollar Rate Margin for
         Revolving Loans with respect to the daily Stated Amount under such
         outstanding Letters of Credit (the "LC Commission"), payable in arrears
         on each Quarterly Payment Date, on the Revolver Termination Date and
         thereafter, on demand. The LC Commission shall be computed on a per
         annum basis from the first day of issuance of each Letter of Credit and
         on the basis of the actual number of days elapsed over a year of 360
         days.

                  (B)   Borrowers agree jointly and severally to pay to Agent
         for distribution to each participating Lender that is not a Defaulting
         Lender in respect of all Rollover Letters of Credit outstanding such
         Lender's Term A Pro Rata Share of a per annum commission equal to the
         Applicable Eurodollar Rate Margin for Revolving Loans with respect to
         the daily Stated Amount under such outstanding Rollover Letters of
         Credit (the "Rollover LC Commission"), payable in arrears on each
         Quarterly Payment Date, on the final expiration date of all Rollover
         Letters of Credit and thereafter, on demand. The Rollover LC Commission
         shall be computed on a per annum basis from the first day of issuance
         of each Rollover Letter of Credit and on the basis of the actual number
         of days elapsed over a year of 360 days.

                  Promptly upon receipt by Facing Agent or Agent of any amount
described in clause (i)(A) with respect to Letters of Credit other then Rollover
Letters of Credit or (ii)(A) of this Section 2.9(e), Facing Agent or Agent shall
distribute to each Lender (other than a Defaulting Lender) that has reimbursed
Facing Agent in accordance with Section 2.9(d) its Revolver Pro Rata Share of
such amount. Promptly upon receipt by Facing Agent or Agent of any amount
described in clause (i)(A) with respect to Rollover Letters of Credit or (ii)(B)
of this Section 2.9(e), Facing Agent or Agent shall distribute to each Lender
(other than a Defaulting Lender) that has reimbursed Facing Agent in accordance
with Section 2.9(d) its Term A Pro Rata Share of such amount. Amounts payable
under clause (i)(B) and (C) of this Section 2.9(e) shall be paid directly to
Facing Agent.

<PAGE>   56

                  (f)   LC Obligations Unconditional. Subject to the last
paragraph of Section 2.9(g), the obligation of Borrowers to reimburse Facing
Agent for drawings made under any Letter of Credit issued by it and the
obligations of each Lender under Section 2.9(d) with respect thereto shall be
joint and several, unconditional and irrevocable and shall be paid strictly in
accordance with the terms of this Agreement under all circumstances (except for
any wrongful payment arising solely out of the willful misconduct, bad faith or
gross negligence of Facing Agent), including, without limitation, any of the
following circumstances:

                  (i)   any lack of validity or enforceability of such Letter of
         Credit;

                  (ii)  the existence of any claim, setoff, defense or other
         right which any Borrower or any of its Affiliates may have at any time
         against a beneficiary or any transferee of such Letter of Credit (or
         any persons or entities for which any such beneficiary or transferee
         may be acting), Facing Agent, any Lender or any other Person, whether
         in connection with this Agreement, the transactions contemplated herein
         or any unrelated transaction (including any underlying transaction
         between any Borrower or one of its Subsidiaries and the beneficiary of
         such Letter of Credit);

                  (iii) any draft, demand, certificate or any other document
         presented under such Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect, provided the same appears
         substantially in compliance with the draw requirements for the Letter
         of Credit;

                  (iv)  payment by Facing Agent under such Letter of Credit
         against presentation of a demand, draft or certificate or other
         document which does not comply with the terms of such Letter of Credit,
         provided the same appears on its face to substantially comply with the
         draw requirements for the Letter of Credit; and

                  (v)   the fact that an Event of Default or an Unmatured Event
         of Default shall have occurred and be continuing.

                  (g)   Indemnification. In addition to amounts payable as
elsewhere provided in this Agreement, each Borrower hereby agrees, jointly and
severally, to protect, indemnify, pay and save Facing Agent harmless from and
against any and all claims, demands, liabilities, damages, losses, costs,
charges and expenses (including reasonable attorneys fees) (other than for
Taxes, which shall be covered by Section 4.7) which Facing Agent may incur or be
subject to as a consequence, direct or indirect, of (i) the issuance of the
Letters of Credit, except to the extent resulting primarily from the gross
negligence, bad faith or willful misconduct of Facing Agent or (ii) the failure
of Facing Agent to honor a drawing under any Letter of Credit as a result of any
act or omissions, whether rightful or wrongful, of any present or future de jure
or de facto government or Governmental Authority (all such acts or omissions
herein called "Government Acts"). As between Borrowers and Facing Agent,
Borrowers assume all risks of the acts and omissions of, or misuse of the
Letters of Credit issued by Facing Agent by, the respective beneficiaries of
such Letters of Credit. In furtherance and not in limitation of the foregoing,
Facing Agent shall not be responsible: (i) for the form, validity, sufficiency,
accuracy, genuineness or legal effect of any document submitted by any party in
connection with the application for and issuance of or any drawing under such
Letters of Credit, even if it should in



                                       55

<PAGE>   57


fact prove to be in any or all respects invalid, insufficient, inaccurate,
fraudulent or forged, provided such document appears on its face to
substantially comply with the requirements applicable to it; (ii) for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) for failure of the beneficiary
of any such Letter of Credit to comply fully with conditions required in order
to draw upon such Letter of Credit; (iv) for errors, omissions, interruptions or
delays in transmission or delivery of any messages, by mail, cable, telegraph,
telex or otherwise, whether or not they be in cipher; (v) for errors in
interpretation of technical terms; (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any such Letter of Credit or of the proceeds thereof; (vii) for the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of any drawing under such Letter of Credit; and (viii) for any consequences
arising from causes beyond the control of Facing Agent, including, without
limitation, any Government Acts. None of the above shall affect, impair, or
prevent the vesting of any of Facing Agent's rights or powers hereunder.

                  In furtherance and extension and not in limitation of the
specific provisions hereinabove set forth, any action taken or omitted by Facing
Agent under or in connection with the Letters of Credit issued by it or the
related certificates, if taken or omitted in good faith, shall not put Facing
Agent under any resulting liability to Borrowers. Notwithstanding anything to
the contrary contained in this Agreement, Borrowers shall have no obligation to
indemnify Facing Agent in respect of any liability incurred by Facing Agent
arising primarily out of the gross negligence, bad faith or willful misconduct
of Facing Agent. The right of indemnification in the first paragraph of this
Section 2.9(g) shall not prejudice any rights that Borrowers may otherwise have
against Facing Agent with respect to a Letter of Credit issued hereunder.

                  (h)  Stated Amount. The Stated Amount of each Letter of Credit
shall not be less than $100,000 or such lesser amount as Facing Agent has agreed
to.

                  (i)  Increased Costs. If at any time after the Closing Date,
Facing Agent or any Lender determines that the introduction of or any change in
any applicable law, rule, regulation, order, guideline or request or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof, or compliance by Facing Agent
or such Lender with any request or directive by any such authority (whether or
not having the force of law), shall either (i) impose, modify or make applicable
any reserve, deposit, capital adequacy or similar requirement against Letters of
Credit issued by Facing Agent or participated in by any Lender, or (ii) impose
on Facing Agent or any Lender any other conditions relating, directly or
indirectly, to this Agreement or any Letter of Credit; and the result of any of
the foregoing is to increase the cost to Facing Agent or any Lender of issuing,
maintaining or participating in any Letter of Credit, or reduce the amount of
any sum received or receivable by Facing Agent or any Lender hereunder or reduce
the rate of return on its capital with respect to Letters of Credit, then, upon
demand to Borrowers by Facing Agent or any Lender (a copy of which demand shall
be sent by Facing Agent or such Lender to Agent), Borrowers shall pay to Facing
Agent or such Lender such additional amount or amounts as will compensate such
Lender for such increased cost or reduction in the amount receivable or
reduction on the rate of return on its capital (but excluding costs resulting
from (A) changes in the rate of tax on, or determined by reference to, the net
income or profits of such Facing Agent



                                       56

<PAGE>   58


or Lender imposed by the jurisdiction in which such Facing Agent's or Lender's
principal office or applicable lending office is located and (B) United States
withholding taxes which shall be governed by the provisions of Section 4.7). In
determining such additional amounts pursuant to the preceding sentence, Facing
Agent or such Lender will act reasonably and in good faith and will, to the
extent the increased costs or reductions in amounts receivable or reductions in
rates of return relate to Facing Agent's or such Lender's letters of credit in
general and are not specifically attributable to the Letters of Credit
hereunder, use averaging and attribution methods which are reasonable and which
cover all letters of credit similar to the Letters of Credit issued by or
participated in by Facing Agent or such Lender whether or not the documentation
for such other Letters of Credit permit Facing Agent or such Lender to receive
amounts of the type described in this Section 2.9(i). Facing Agent or any
Lender, upon determining that any additional amounts will be payable pursuant to
this Section 2.9(i), will give prompt written notice thereof to Borrowers, which
notice shall include a certificate submitted to Borrowers by Facing Agent or
such Lender (a copy of which certificate shall be sent by Facing Agent or such
Lender to Agent), setting forth in reasonable detail the basis for the
calculation of such additional amount or amounts necessary to compensate Facing
Agent or such Lender, although failure to give any such notice shall not release
or diminish Borrowers' obligations to pay additional amounts pursuant to this
Section 2.9(i) provided that Borrowers shall not be required to compensate a
Lender or Facing Agent pursuant to this section for any increased costs or
reductions incurred more than 180 days prior to the date that such Lender or
Facing Agent, as the case may be, notifies Borrower in writing of the additional
amounts and of such Lender's or Facing Agent's intention to claim compensation
therefor; provided further that, if the change in law giving rise to such
increased costs or reductions is retroactive, then the 180-day period referred
to above shall be extended to include the period of retroactive effect thereof.
The certificate required to be delivered pursuant to this Section 2.9(i) shall,
absent manifest error, be final, conclusive and binding on Borrowers and Facing
Agent or the Lender, as applicable.

                                  ARTICLE III
                                INTEREST AND FEES

                  Section 3.1. Interest.

                  (a)  Base Rate Loans. Borrowers agree jointly and severally to
pay interest in respect of the unpaid principal amount of each Base Rate Loan at
a rate per annum equal to the Base Rate plus the Applicable Base Rate Margin
from the date the proceeds thereof are made available to Borrowers until the
earlier of (i) the maturity (whether by acceleration or otherwise) of such Base
Rate Loan or (ii) the conversion of such Base Rate Loan to a Eurodollar Loan
pursuant to Section 2.6.

                  (b)  Eurodollar Loans. Borrowers agree jointly and severally
to pay interest in respect of the unpaid principal amount of each Eurodollar
Loan from the date the proceeds thereof are made available to Borrowers until
the earlier of (i) the maturity (whether by acceleration or otherwise) of such
Eurodollar Loan or (ii) the conversion of such Eurodollar Loan to a Base Rate
Loan pursuant to Section 2.6 at a rate per annum equal to the relevant
Eurodollar Rate plus the Applicable Eurodollar Rate Margin.



                                       57
<PAGE>   59


                  (c)  Payment of Interest. Interest on each Loan shall be
payable in arrears on each Interest Payment Date; provided, however, that
interest accruing pursuant to Section 3.1(e) shall be payable from time to time
on demand. Interest shall also be payable on all then outstanding Acquisition
Revolving Loans on the Acquisition Revolver Conversion Date, on all then
outstanding Revolving Loans on the Revolver Termination Date, on all then
outstanding Swing Line Loans on the fifth (5th) Business Day prior to the
Revolver Termination Date, and on all Loans on the date of repayment (including
prepayment) thereof (except that (i) voluntary prepayments of Revolving Loans
that are Base Rate Loans made pursuant to Section 4.3 on any day other than a
Quarterly Payment Date or the Revolver Termination Date or Acquisition Revolver
Conversion Date need not be made with accrued interest from the most recent
Quarterly Payment Date, provided such accrued interest is paid on the next
Quarterly Payment Date and (ii) voluntary prepayment of Swing Line Loans made
pursuant to Section 4.3 on any day other than a Quarterly Payment Date or on the
fifth Business Day prior to the Revolver Termination Date need not be made with
accrued interest from the most recent Quarterly Payment Date, provided such
accrued interest is paid on the next Quarterly Payment Date) and on the date of
maturity (by acceleration or otherwise) of such Loans. During the existence of
any Event of Default, interest on any Loan shall be payable on demand.

                  (d)  Notification of Rate. Agent, upon determining the
interest rate for any Borrowing of Eurodollar Loans for any Interest Period,
shall promptly notify Borrowers and the Lenders thereof. Such determination
shall, absent manifest error and subject to Section 3.6, be final, conclusive
and binding upon all parties hereto.

                  (e)  Default Interest. Notwithstanding the rates of interest
specified herein, effective immediately upon any failure to pay any Obligations
or any other amounts due under any of the Loan Documents when due, whether by
acceleration or otherwise, the principal balance of each Loan then outstanding
and, to the extent permitted by applicable law, any interest payment on each
Loan not paid when due or other amounts then due and payable shall bear interest
payable on demand, after as well as before judgment at a rate per annum equal to
the Default Rate.

                  (f)  Maximum Interest. If any interest payment or other charge
or fee payable hereunder exceeds the maximum amount then permitted by applicable
law, Borrowers shall be jointly and severally obligated to pay the maximum
amount then permitted by applicable law and Borrowers shall continue to pay the
maximum amount from time to time permitted by applicable law until all such
interest payments and other charges and fees otherwise due hereunder (in the
absence of such restraint imposed by applicable law) have been paid in full.

                  Section 3.2. Fees.

                  (a)  Commitment Fee. Borrowers agree jointly and severally to
pay to Agent for pro rata distribution to each Non-Defaulting Lender having a
Revolving Commitment (based on its Revolver Pro Rata Share) a commitment fee
(the "Commitment Fee") for the period commencing on the Initial Borrowing Date
to and including the Revolver Termination Date or the earlier termination of the
Revolving Commitments (and, in either case, repayment in full of the Revolving
Loans and payment in full, or cash collateralization by the deposit of cash into
the Collateral Account in amounts and pursuant to arrangements satisfactory to
Agent, of the LC



                                       58

<PAGE>   60

Obligations), computed at a rate equal to the Applicable Commitment Fee
Percentage per annum on the average daily Total Available Revolving Commitment.
Unless otherwise specified, accrued Commitment Fees shall be due and payable (i)
on each Quarterly Payment Date, (ii) on the Revolver Termination Date and (iii)
upon any reduction or termination in whole or in part of the Revolving
Commitments (but only, in the case of a reduction, on the portion of the
Revolving Commitments then being reduced).

                  (b)   Agency Fees. Borrowers agree jointly and severally to
pay to Agent for its own account, agency and other Loan fees in the amount and
at the times set forth in the letter agreement between Borrower and Agent.

                  Section 3.3. Computation of Interest and Fees; Changes in
Margins and Fees. Interest on all Loans and fees payable hereunder shall be
computed on the basis of the actual number of days elapsed over a year of 360
days; provided that interest on all Base Rate Loans based on the prime lending
rate shall be computed on the basis of the actual number of days elapsed over a
year of 365 or 366 days, as the case may be. Each determination of an interest
rate by Agent pursuant to any provision of this Agreement shall be conclusive
and binding on Borrowers and the Lenders in the absence of manifest error. Agent
shall, at any time and from time to time upon request of Borrowers, deliver to
Borrowers a statement showing the quotations used by Agent in determining any
interest rate applicable to Eurodollar Loans pursuant to this Agreement. Each
change in the Applicable Base Rate Margin, Applicable Eurodollar Margin, LC
Commission, Rollover LC Commission or Applicable Commitment Fee Percentage as a
result of a change in Borrower's Most Recent Ratio of Total Debt to EBITDA shall
become effective on the date upon which financial statements reporting such
change are delivered to Agent pursuant to Section 7.1 and shall continue to be
effective until the next date on which financial statements reporting such
change are delivered pursuant to Section 7.1, in each case subject to the
proviso in the definition of "Most Recent Ratio of Total Debt to EBITDA".

                  Section 3.4. Interest Periods. At the time it gives any Notice
of Borrowing or a Notice of Conversion or Continuation with respect to
Eurodollar Loans, a Borrower shall elect, by giving Agent written notice, the
interest period (each an "Interest Period") which Interest Period shall, at the
option of such Borrower, be one, two, three or six months or, if available to
each of the applicable Lenders (as determined by each such applicable Lender in
its sole discretion) a nine or twelve month period, or during the Syndication
Period only, a period of up to 14 days provided that:

                  (i)   all Eurodollar Loans comprising a Borrowing shall at all
         times have the same Interest Period;

                  (ii)  the initial Interest Period for any Eurodollar Loan
         shall commence on the date of such Borrowing of such Eurodollar Loan
         (including the date of any conversion thereto from a Loan of a
         different Type) and each Interest Period occurring thereafter in
         respect of such Eurodollar Loan shall commence on the last day of the
         immediately preceding Interest Period;

                  (iii) if any Interest Period relating to a Eurodollar Loan
         begins on a day for which there is no numerically corresponding day in
         the calendar month at the end of such Interest Period, such


                                       59

<PAGE>   61

         Interest Period shall end on the last Business Day of such calendar
         month;

                  (iv)  if any Interest Period would otherwise expire on a day
         which is not a Business Day, such Interest Period shall expire on the
         next succeeding Business Day; provided, however, that if any Interest
         Period for a Eurodollar Loan would otherwise expire on a day which is
         not a Business Day but is a day of the month after which no further
         Business Day occurs in such month, such Interest Period shall expire on
         the next preceding Business Day;

                  (v)   no Interest Period may be selected at any time when an
         Unmatured Event of Default or Event of Default is then in existence;

                  (vi)  no Interest Period shall extend beyond the Term A Loan
         Maturity Date for any Term A Loan, the Term B Loan Maturity Date for
         any Term B Loan or the Revolver Termination Date for any Revolving
         Loan; and

                  (vii) no Interest Period in respect to any Borrowing of Term
         Loans shall be selected which extends beyond any date upon which a
         mandatory repayment of Term Loans will be required to be made under
         Section 4.4(b), (c), (d), (e), (f), or (h), as the case may be, if the
         aggregate principal amount of Term Loans which have Interest Periods
         which will expire after such date will be in excess of the aggregate
         principal amount of Term Loans then outstanding less the aggregate
         amount of such required prepayment.

                  Section 3.5. Compensation for Funding Losses.

                  (a)   Borrowers agree jointly and severally to compensate each
Lender, upon its written request (which request shall set forth in reasonable
detail the basis for requesting such amounts), for all losses, expenses and
liabilities (including, without limitation, any interest paid by such Lender to
lenders of funds borrowed by it to make or carry its Eurodollar Loans to the
extent not recovered by the Lender in connection with the liquidation or
re-employment of such funds and including the compensation payable by such
Lender to a Participant but excluding loss of anticipated profit with respect to
any Loans) and any loss sustained by such Lender in connection with the
liquidation or re-employment of such funds (including, without limitation, a
return on such liquidation or re-employment that would result in such Lender
receiving less than it would have received had such Eurodollar Loan remained
outstanding until the last day of the Interest Period applicable to such
Eurodollar Loans) which such Lender may sustain as a result of: (i) for any
reason (other than a default by such Lender or Agent) a continuation or
Borrowing of, or conversion from or into, Eurodollar Loans does not occur on a
date specified therefor in a Notice of Borrowing or Notice of Conversion or
Continuation (whether or not withdrawn); (ii) any payment, prepayment or
conversion or continuation of any of its Eurodollar Loans occurring for any
reason whatsoever on a date which is not the last day of an Interest Period
applicable thereto; (iii) any repayment of any of its Eurodollar Loans not being
made on the date specified in a notice of payment given by a Borrower; or (iv)
(A) any other failure by Borrowers to repay Eurodollar Loans when required by
the terms of this Agreement or (B) an election made by a Borrower pursuant to
Section 3.7. A written notice as to additional amounts owed such Lender


                                       60

<PAGE>   62


under this Section 3.5 and delivered to Borrowers and Agent by such Lender
shall, absent manifest error, be final, conclusive and binding for all purposes;
provided that Borrowers shall not be required to compensate such Lender pursuant
to this Section for any losses, expenses and liabilities incurred more than 180
days prior to the date that such Lender notifies Borrowers thereof.

                  (b)   Calculation of all amounts payable to a Lender under
this Section 3.5 shall be made as though that Lender had actually funded its
relevant Eurodollar Loan through the purchase of a Eurodollar deposit bearing
interest at the Eurodollar Rate in an amount equal to the amount of that Loan,
having a maturity comparable to the relevant Interest Period and through the
transfer of such Eurodollar deposit from an offshore office of that Lender to a
domestic office of that Lender in the United States of America; provided,
however, that each Lender may fund each of its Eurodollar Loans in any manner it
sees fit and the foregoing assumption shall be utilized only for the calculation
of amounts payable under this Section 3.5.

                  Section 3.6. Increased Costs, Illegality, Etc.

                  (a)   Generally. In the event that any Lender shall have
determined (which determination shall, absent manifest error, be final and
conclusive and binding upon all parties hereto but, with respect to clause (i)
below, may be made only by Agent):

                  (i)   on any Interest Rate Determination Date that, by reason
         of any changes arising after the Closing Date affecting the interbank
         Eurodollar market, adequate and fair means do not exist for
         ascertaining the applicable interest rate on the basis provided for in
         the definition of Eurodollar Rate; or

                  (ii)  at any time, that any Lender shall incur increased costs
         or reduction in the amounts received or receivable hereunder with
         respect to any Eurodollar Loan because of (x) any change since the
         Closing Date in any applicable law or governmental rule, regulation,
         order, guideline or request (whether or not having the force of law) or
         in the interpretation or administration thereof and including the
         introduction of any new law or governmental rule, regulation, order,
         guideline or request, such as, for example, but not limited to: (A) a
         change in the basis of taxation of payments to any Lender of the
         principal of or interest on the Obligations or any other amounts
         payable hereunder (except for (a) changes in the rate of tax on, or
         determined by reference to, the net income or profits of such Lender
         imposed by the jurisdiction in which its principal office or applicable
         lending office is located and (b) United States withholding taxes,
         which shall be governed by the provisions of Section 4.7) or (B) a
         change in official reserve requirements (but, in all events, excluding
         reserves required under Regulation D to the extent included in the
         computation of the Eurodollar Rate) and/or (y) other circumstances
         since the Closing Date affecting such Lender or the interbank
         Eurodollar market or the position of such Lender in such market
         (excluding, however, differences in a Lender's cost of funds from those
         of Agent which are solely the result of credit differences between such
         Lender and Agent); or

                  (iii) at any time, that the making or continuance of any
         Eurodollar Loan has been made (x) unlawful by any law or governmental
         rule, regulation or order, (y)



                                       61

<PAGE>   63


         impossible by compliance by any Lender in good faith with any
         governmental request (whether or not having force of law) or (z)
         impracticable as a result of a contingency occurring after the date of
         this Agreement which materially and adversely affects the interbank
         Eurodollar market; then, and in any such event, such Lender (or Agent,
         in the case of clause (i) above) shall promptly give notice (by
         telephone confirmed in writing) to Borrowers and, except in the case of
         clause (i) above, to Agent of such determination (which notice Agent
         shall promptly transmit to each of the other Lenders). Thereafter (x)
         in the case of clause (i) above, Eurodollar Loans shall no longer be
         available until such time as Agent notifies Borrowers and the Lenders
         that the circumstances giving rise to such notice by Agent no longer
         exist (which notice Agent shall promptly transmit upon learning of the
         availability of Eurodollar Loans), and any Notice of Borrowing or
         Notice of Conversion or Continuation given by any Borrower with respect
         to Eurodollar Loans (other than with respect to conversions to Base
         Rate Loans) which have not yet been incurred (including by way of
         conversion) shall be deemed rescinded by Borrowers, (y) in the case of
         clause (ii) above, Borrowers agree jointly and severally to pay to such
         Lender, upon written demand therefor, such additional amounts (in the
         form of an increased rate of, or a different method of calculating,
         interest or otherwise as such Lender in its sole discretion shall
         determine) as shall be required to compensate such Lender for such
         increased costs or reductions in amounts received or receivable
         hereunder (a written notice as to the additional amounts owed to such
         Lender, showing in reasonable detail the basis for the calculation
         thereof, submitted to Borrowers by such Lender shall, absent manifest
         error, be final and conclusive and binding on all the parties hereto;
         however the failure to give any such notice shall not release or
         diminish Borrowers' obligations to pay additional amounts pursuant to
         this Section 3.6 (a)(y)) provided that Borrowers shall not be required
         to compensate such Lender pursuant to this section for any increased
         costs or reductions incurred more than 180 days prior to the date that
         such Lender notifies Borrowers in writing of the increased costs or
         reductions and of such Lender's intention to claim compensation
         therefor; provided further that, if the change in law giving rise to
         such increased costs or reductions is retroactive, then the 180-day
         period referred to above shall be extended to include the period of
         retroactive effect thereof and (z) in the case of clause (iii) above,
         Borrowers shall take one of the actions specified in Section 3.6(b) as
         promptly as possible and, in any event, within the time period required
         by law. In determining such additional amounts pursuant to clause (y)
         of the immediately preceding sentence, each Lender shall act reasonably
         and in good faith and will, to the extent the increased costs or
         reductions in amounts receivable relate to such Lender's loans in
         general and are not specifically attributable to a Loan hereunder, use
         averaging and attribution methods which are reasonable and which cover
         all loans similar to the Loans made by such Lender whether or not the
         loan documentation for such other loans permits the Lender to receive
         increased costs of the type described in this Section 3.6(a).


                  (b)  Eurodollar Loans. At any time that any Eurodollar Loan is
affected by the circumstances described in Section 3.6(a)(ii) or (iii),
Borrowers may (and, in the case of a Eurodollar Loan affected by the
circumstances described in Section 3.6(a)(iii), shall) either (i) if the
affected Eurodollar Loan is then being made initially or pursuant to a
conversion, by giving Agent telephonic notice (confirmed in writing) on the same
date that Borrowers were notified by the affected Lender or Agent pursuant to
Section 3.6(a)(ii) or (iii), cancel the respective



                                       62

<PAGE>   64

Borrowing, or (ii) if the affected Eurodollar Loan is then outstanding, upon at
least three Business Days' written notice to Agent, require the affected Lender
to convert such Eurodollar Loan into a Base Rate Loan, provided, that if more
than one Lender is affected at any time, then all affected Lenders must be
treated the same pursuant to this Section 3.6(b).

                  (c)   Capital Requirements. If any Lender determines that the
introduction of or any change in any applicable law or governmental rule,
regulation, order, guideline or request (whether or not having the force of law)
concerning capital adequacy, or any change in (after the Closing Date)
interpretation or administration thereof by any Governmental Authority, central
bank or comparable agency, will have the effect of increasing the amount of
capital required or expected to be maintained by such Lender or any corporation
controlling such Lender based on the existence of such Lender's Commitments
hereunder or its obligations hereunder, then Borrowers agree jointly and
severally to pay to such Lender, upon its written demand therefor, such
additional amounts as shall be required to compensate such Lender or such other
corporation for the increased cost to such Lender or such other corporation or
the reduction in the rate of return to such Lender or such other corporation as
a result of such increase of capital. In determining such additional amounts,
each Lender will act reasonably and in good faith and will use averaging and
attribution methods which are reasonable and which will, to the extent the
increased costs or reduction in the rate of return relates to such Lender's
commitments or obligations in general and are not specifically attributable to
the Commitments and obligations hereunder, cover all commitments and obligations
similar to the Commitments and obligations of such Lender hereunder whether or
not the loan documentation for such other commitments or obligations permits the
Lender to make the determination specified in this Section 3.6(c), and such
Lender's determination of compensation owing under this Section 3.6(c) shall,
absent manifest error, be final and conclusive and binding on all the parties
hereto. Each Lender, upon determining that any additional amounts will be
payable pursuant to this Section 3.6(c), will give prompt written notice thereof
to Borrowers, which notice shall show in reasonable detail the basis for
calculation of such additional amounts, although the failure to give any such
notice shall not release or diminish any of Borrowers' obligations to pay
additional amounts pursuant to this Section 3.6(c) provided that Borrowers shall
not be required to compensate such Lender pursuant to this Section for any
increased costs or reductions incurred more than 180 days prior to the date that
such Lender notifies Borrowers in writing of the increased costs or reductions
and of such Lender's intention to claim compensation thereof; provided further
that, if the change in law giving rise to such increased costs or reductions is
retroactive, then the 180-day period referred to above shall be extended to
include the period of retroactive effect thereof.

                  (d)   Change of Lending Office. Each Lender which is or will
be owed compensation pursuant to Section 3.6(a) or (c) or Section 2.9(i) will,
if requested by Borrowers, use reasonable efforts (subject to overall policy
considerations of such Lender) to cause a different branch or Affiliate to make
or continue a Loan or Letter of Credit if such designation will avoid the need
for, or materially reduce the amount of, such compensation to such Lender and
will not, in the judgment of such Lender, be otherwise disadvantageous to such
Lender as determined by such Lender in its sole discretion and will not result
in the imposition upon Borrowers of an increased liability for Taxes pursuant to
Section 3.6(a) or (c), Section 2.9(i) or Section 4.7. Borrowers hereby agree
jointly and severally to pay all reasonable expenses incurred by any Lender in
utilizing a different branch or Affiliate pursuant to this Section 3.6(d).

Nothing in this Section 3.6(d) shall affect or postpone any of the obligations
of any Borrower or the right of any Lender provided for herein.

                  Section 3.7. Replacement of Affected Lenders. (x) If any
Revolving Lender becomes a Defaulting Lender or otherwise defaults in its
Obligations to make Loans or fund Unpaid Drawings, (y) if any Lender (or in the
case of Section 2.9(i), Facing Agent) is owed increased costs under Section
3.6(a)(ii) or (iii), Section 3.6(c), Section 2.9(i), or any Borrower is required
to make any payments under Section 4.7(c) to any Lender, in each case materially
in excess of those to the other Lenders or (z) as provided in Section 12.1(b) in
the case of refusals by a Lender to consent to proposed amendments, changes,
supplements, waivers, discharges or terminations with respect to this Agreement
which have been approved by the Required Lenders, Borrowers shall have the
right, if no Event of Default or Unmatured Event of Default then exists, to
replace such Lender (the "Replaced Lender") with one or more other Eligible
Assignee or Eligible Assignees, none of whom shall constitute a Defaulting
Lender at the time of such replacement (collectively, the "Replacement Lender")
reasonably acceptable to Agent, provided that (i) at the time of any replacement
pursuant to this Section 3.7, the Replacement Lender shall enter into one or
more assignment agreements, in form and substance reasonably satisfactory to
Agent, pursuant to which the Replacement Lender shall acquire all of the
Commitments and outstanding Loans of, and participation in Letters of Credit and
Swing Line Loans by, the Replaced Lender and (ii) all obligations of Borrowers
owing to the Replaced Lender (including, without limitation, such increased
costs and excluding those specifically described in clause (i) above in respect
of which the assignment purchase price has been, or is concurrently being paid)
shall be paid in full to such Replaced Lender concurrently with such
replacement. Upon the execution of the respective assignment documentation, the
payment of amounts referred to in clauses (i) and (ii) above and, if so
requested by the Replacement Lender, delivery to the Replacement Lender of the
appropriate Note or Notes executed by Borrowers, the Replacement Lender shall
become a Lender hereunder and the Replaced Lender shall cease to constitute a
Lender hereunder, except with respect to indemnification provisions under this
Agreement, which shall survive as to such Replaced Lender. Notwithstanding
anything to the contrary contained above, no Lender that acts as a Facing Agent
may be replaced hereunder at any time which it has Letters of Credit outstanding
hereunder unless arrangements reasonably satisfactory to such Facing Agent
(including the furnishing of a standby letter of credit in form and substance,
and issued by an issuer reasonably satisfactory to such Facing Agent or the
depositing of cash collateral into the Collateral Account in amounts and
pursuant to arrangements reasonably satisfactory to such Facing Agent) have been
made with respect to such outstanding Letters of Credit.

                                   ARTICLE IV
               REDUCTION OF COMMITMENTS; PAYMENTS AND PREPAYMENTS

                  Section 4.1. Voluntary Reduction of Commitments. (a) Upon at
least three (3) Business Days' prior written notice (or telephonic notice
confirmed in writing) to Agent at the Notice Office (which notice Agent shall
promptly transmit to each Lender), Borrower shall have the right, without
premium or penalty, to terminate the unutilized portion of the Revolving
Commitments or the Swing Line Commitment, as the case may be, in part or in
whole; provided that (i) any such voluntary termination of the Revolving
Commitments shall apply to proportionately and permanently reduce the Revolving
Commitment of each Revolving Lender,



                                       64

<PAGE>   66
 (ii)  any partial voluntary reduction pursuant to this Section 4.1 shall be in
the amount of at least $5,000,000 and integral multiples of $1,000,000 in excess
of that amount, (iii) any such voluntary termination of the Revolving
Commitments shall occur simultaneously with a voluntary prepayment, pursuant to
Section 4.3 such that the total of the Revolving Commitments shall not be
reduced below the aggregate principal amount of outstanding Acquisition
Revolving Loans and Working Capital Loans plus the aggregate LC Obligations and
the Swing Line Commitment, as the case may be and (iv) no partial voluntary
reduction shall occur prior to the Acquisition Revolver Conversion Date.

                  (b)   In the event of refusals by a Lender to consent to
proposed changes, waivers, discharges or terminations with respect to this
Agreement which have been approved by the Required Lenders as provided in
Section 12.1(b), Borrowers shall have the right, upon three (3) Business Days'
prior written notice to Agent (which notice Agent shall promptly transmit to
each of the Lenders), to terminate the entire Revolving Commitment and Term A
Commitment of such Lender, so long as all Loans, together with accrued and
unpaid interest, fees and all other amounts, due and owing to such Lender are
repaid concurrently with the effectiveness of such termination at which time
Schedule 1.1(a) shall be deemed modified to reflect such changed amounts
pursuant to Section 4.3(b) and Borrowers cash collateralize such Lender's
Revolver Pro Rata Share and/or Term A Pro Rata Share of the LC Obligations and
Rollover LC Obligations (in the manner set forth in Section 4.4(a)) then
outstanding. At such time, such Lender shall no longer constitute a "Lender" for
purposes of this Agreement, except with respect to indemnifications under this
Agreement which shall survive as to such repaid Lender.

                  Section 4.2. Mandatory Reductions of Commitments.

                  (a)   Reduction of Revolving Commitments. The Revolving
Commitments shall be reduced at the time and in the amounts required to be
reduced pursuant to Section 4.4(c), (d), (e), (f) and (g). On the Acquisition
Revolver Conversion Date, the Revolving Commitments shall be reduced by an
amount equal to the greater of (i) the aggregate principal amount of all
outstanding Acquisition Term Loans on such date immediately after giving effect
to the conversion of Acquisition Revolving Loans into Acquisition Term Loans on
such date and (ii) $50,000,000.

                  (b)   Reduction of Term Commitments. The Term A Commitments
shall be reduced on the Initial Borrowing Date by the aggregate principal amount
of Term A Loans funded on such date and on any subsequent date of funding of any
Term A Loans, to the extent and on such date of any subsequent funding of any
Term A Loans, and the remaining portion of the Term A Commitments, if any, shall
terminate on the expiration date of the Rollover Letters of Credit. The Term B
Commitments shall terminate on the Initial Borrowing Date, after giving effect
to the Borrowing of Term B Loans on such date.

                  (c)   Proportionate Reductions. Each reduction or adjustment
to the Term A Commitments, Term B Commitments or the Revolving Commitments
pursuant to this Section 4.2 shall apply proportionately to the Term A
Commitments, Term B Commitments or the Revolving Commitment, as the case may be,
 of each Lender.


                                       65

<PAGE>   67

                  (d)   Reduction of Commitments. The Commitments will terminate
in their entirety on December 15, 1999 unless the Initial Borrowing Date has
occurred on or before such date.

                  (e)   Reductions Following Term Loan Repayments. In addition
to any other mandatory commitment reductions pursuant to this Section 4.2, on
each date upon which a mandatory repayment of Term Loans pursuant to Section 4.4
(other than pursuant to Section 4.4(d)) is required (and exceeds the aggregate
principal amount of Term Loans then outstanding) or would be required if Term
Loans were then outstanding, the Total Available Revolving Commitment shall be
permanently reduced by the amount, if any, by which the amount required to be
applied pursuant to said Section 4.4 (determined as if an unlimited amount of
Term Loans were actually outstanding) exceeds the aggregate principal amount of
Term Loans then outstanding.

                  Section 4.3. Voluntary Prepayments. (a) Borrowers shall have
the right to prepay the Loans in whole or in part from time to time on the
following terms and conditions: (i) Borrowers shall give Agent irrevocable
written notice at its Notice Office (or telephonic notice promptly confirmed in
writing) of its intent to prepay the Loans or Swing Line Loans, the amount of
such prepayment and the specific Borrowings to which such prepayment is to be
applied, which notice shall be given by Borrowers to Agent by 12:00 noon (New
York City time) (x) on the date of prepayment with respect to Revolving Loans
and Swing Line Loans which are Base Rate Loans, (y) at least one Business Day
prior to the date of such prepayment with respect to Term Loans that are Base
Rate Loans and (z) at least three Business Days prior to the date of such
prepayment with respect to Eurodollar Loans and which notice shall (except in
the case of Swing Line Loans) promptly be transmitted by Agent to each of the
applicable Lenders; (ii) each partial prepayment of any Borrowing (other than a
Borrowing of Swing Line Loans) shall be in an aggregate principal amount of at
least $1,000,000 and each partial prepayment of a Swing Line Loan shall be in an
aggregate principal amount of at least $500,000; provided that no partial
prepayment of Eurodollar Loans made pursuant to a single Borrowing shall reduce
the aggregate principal amount of the outstanding Loans made pursuant to such
Borrowing to an amount less than the Minimum Borrowing Amount applicable
thereto; (iii) Eurodollar Loans may only be prepaid pursuant to this Section 4.3
on the last day of an Interest Period applicable thereto or on any other day
subject to Section 3.5; (iv) each prepayment in respect of any Borrowing shall
be applied pro rata among the Loans comprising such Borrowing provided, that
such prepayment shall not be applied to any Revolving Loans of a Defaulting
Lender at any time when the aggregate amount of Revolving Loans of any
Non-Defaulting Lender exceeds such Non-Defaulting Lender's Revolver Pro Rata
Share of all Revolving Loans then outstanding; and (v) in the event that all or
any portion of the Term B Loans are prepaid on or before the second anniversary
of the Closing Date, such prepayment shall be made at 101% of the principal
amount of the Term B Loan repaid. Voluntary prepayments of Term Loans shall be
applied first to the unpaid Scheduled Term A Repayments, the Scheduled Term B
Repayments and Scheduled Acquisition Repayments due within the 12 month period
following the date of such prepayment in direct order of maturity and,
thereafter, shall be applied in proportional amounts equal to the Term A
Percentage, Term B Percentage and Acquisition Percentage (in each case, after
giving effect to the prepayments made to the unpaid Scheduled Term A Repayments,
Scheduled Term B Repayments and Scheduled Acquisition Repayments due within such
twelve month period as specified above), as the case may be, of such remaining
prepayment, if any, and within each



                                       66

<PAGE>   68

Term Loan, shall be applied to reduce the remaining Scheduled Term A Repayments,
Scheduled Term B Repayments and Scheduled Acquisition Repayments on a pro rata
basis. Unless otherwise specified by Borrower, such prepayment shall be applied
first to the payment of Base Rate Loans and second to the payment of such
Eurodollar Loans as Borrower shall request (and in the absence of such request,
as Agent shall determine so as to minimize, if possible, any amounts due under
Section 3.5). The notice provisions, the provisions with respect to the minimum
amount of any prepayment, and the provisions requiring prepayments in integral
multiples above such minimum amount of this Section 4.3 are for the benefit of
Agent and may be waived unilaterally by Agent.

                  (b)   In the event of refusals by a Lender to consent to
proposed changes, waivers, discharges or terminations with respect to this
Agreement which have been approved by the Required Lenders as provided in
Section 12.1(b), Borrowers shall have the right, upon three (3) Business Days'
prior written notice to Agent (which notice Agent shall promptly transmit to
each of the Lenders), to repay all Loans, together with accrued and unpaid
interest, fees and all other amounts due and owing to such Lender in accordance
with said Section 12.1(b), so long as (A) in the case of the repayment of
Revolving Loans of any Revolving Lender pursuant to this clause (b), the
Revolving Commitment of such Revolving Lender is terminated concurrently with
such repayment pursuant to Section 4.1(b) and, in the case of the repayment of
Term A Loans of any Term A Lender pursuant to this clause (b), the Term A
Commitment of such Term A Lender is terminated concurrently with such repayment
pursuant to Section 4.1(b) and (c) and (B) in the case of the repayment of Loans
of any Lender, the consents required by Section 12.1(b) in connection with the
repayment pursuant to this clause (b) shall have been obtained.

                  Section 4.4. Mandatory Prepayments.

                  (a)   Prepayment Upon Overadvance. Borrowers shall prepay the
outstanding principal amount of the Acquisition Revolving Loans, Working Capital
Loans or the Swing Line Loan on any date on which the aggregate outstanding
principal amount of such Loans together with the aggregate LC Obligations (after
giving effect to any other repayments or prepayments on such day) exceeds the
aggregate Revolving Commitments or the Swing Line Commitment, as the case may
be, in the amount of such excess. In addition, Borrowers shall prepay the
outstanding principal amount of (i) Acquisition Revolving Loans on any date on
which the aggregate outstanding principal amount of Acquisition Revolving Loans
exceeds the Acquisition Revolving Sublimit and (ii) Working Capital Loans on any
date on which the aggregate outstanding principal amount of Working Capital
Loans, when added to the then outstanding Swing Line Loans and the aggregate LC
Obligations, exceeds the Working Capital Sublimit, in each case in the amount of
such excess. If, after giving effect to the prepayment of all outstanding
Acquisition Revolving Loans and Working Capital Loans, the aggregate LC
Obligations exceeds the Revolving Commitments then in effect, Borrowers shall
cash collateralize LC Obligations by depositing, pursuant to a cash collateral
agreement to be entered into in form and substance reasonably satisfactory to
Agent, cash with Agent in an amount equal to the difference between such LC
Obligations and the Revolving Commitments then in effect. Agent shall establish
in its name for the benefit of the Revolving Lenders a cash collateral account
(the "Collateral Account") into which it shall deposit such cash to hold as
collateral security for the LC Obligations.

                  (b)   Scheduled Term Repayments.

                  (i)   Scheduled Term A Repayments. Borrowers agree jointly and
         severally to pay Scheduled Term A Repayments on the Term A Loans until
         the Term A Loans are paid in full in the amounts and at the times
         specified in the definition of Scheduled Term A Repayments to the
         extent that prepayments have not previously been applied to such
         Scheduled Term A Repayments (and such Scheduled Term A Repayments have
         not otherwise been reduced) pursuant to the terms hereof.

                  (ii)  Scheduled Term B Repayments. Borrowers agree jointly and
         severally to pay Scheduled Term B Repayments on the Term B Loans until
         the Term B Loans are paid in full in the amounts and at the times
         specified in the definition of Scheduled Term B Repayments to the
         extent that prepayments have not previously been applied to such
         Scheduled Term B Repayments (and such Scheduled Term B Repayments have
         not otherwise been reduced) pursuant to the terms hereof.

                  (iii) Scheduled Acquisition Repayments. Borrowers agree
         jointly and severally to pay Scheduled Acquisition Repayments on the
         Acquisition Term Loans until the Acquisition Term Loans are repaid in
         full in the amounts and at the times specified in the definition of
         Scheduled Acquisition Repayments to the extent that prepayments have
         not previously been applied to such Scheduled Acquisition Repayments
         (and such Scheduled Acquisition Repayments have not otherwise been
         reduced) pursuant to the terms hereof.

                  (c)   Mandatory Prepayment Upon Asset Disposition. On the
first Business Day after the date of receipt thereof by Holdings, Borrowers
and/or any of their Subsidiaries of Net Sale Proceeds from any Asset
Disposition, an amount equal to 100% of the Net Sale Proceeds from such Asset
Disposition shall be applied as a mandatory repayment of principal of the Loans
as provided in Section 4.5, in each case subject to modification of such
application as set forth in Section 4.5(d), provided, that with respect to no
more than $5,000,000 in the aggregate of such Net Sale Proceeds (but excluding
any Net Sale Proceeds from any Designated Asset Disposition) in any Fiscal Year
of Holdings, the Net Sale Proceeds therefrom shall not be required to be so
applied on such date to the extent that no Event of Default or Unmatured Event
of Default then exists at the time of receipt of such proceeds and Borrowers
deliver a certificate to Agent on or prior to such date stating that such Net
Sale Proceeds shall be used or contractually committed to be used to purchase
assets used or to be used in the businesses referred to in Section 8.12 within
180 days following the date of such Asset Disposition (which certificate shall
set forth the estimates of the proceeds to be so expended), provided, further,
that (1) if all or any portion of such Net Sale Proceeds not so applied to the
repayment of Loans are not so used (or contractually committed to be used)
within such 180 day period, such remaining portion shall be applied on the last
day of such 180 day period as a mandatory repayment of principal of outstanding
Loans as provided above in this Section 4.4(c) and (2) if all or any portion of
such Net Sale Proceeds are not required to be applied on the 180th day referred
to above because such amount is contractually committed to be used and
subsequent to such date such contract is terminated or expires without such
portion being so used, then such remaining portion shall be applied on the date
of such termination or expiration as a mandatory repayment of principal of
outstanding Term Loans as provided in this Section 4.4(c), and provided,
further,





                                       68
<PAGE>   70

that Net Sale Proceeds from any Designated Asset Disposition shall be applied as
a mandatory repayment of principal of Acquisition Loans as provided in Section
4.5 in an amount equal to the aggregate principal amount of Acquisition Loans
incurred to finance the Permitted Acquisition which relates to such Designated
Asset Disposition, and any excess Net Sale Proceeds, after giving effect to such
repayment, shall be required to be so applied to the repayment of the Loans as
provided above.

                  (d) Mandatory Prepayment With Excess Cash Flow. On each Excess
Cash Payment Date, an amount equal to 50% of Excess Cash Flow, if positive, of
Holdings and its Subsidiaries for the most recent Excess Cash Flow Period ending
prior to such Excess Cash Payment Date shall be applied as a mandatory repayment
of principal of the Loans as provided in Section 4.5 in each case subject to
modification of such application as set forth in Section 4.5(d).

Subsidiaries shall be applied as a mandatory repayment of principal of the Term
Loans as provided in Section 4.5 in each case subject to modification of such
application as set forth in Section 4.5(d); provided, however, that so long as
no Event of Default or Unmatured Event of Default (but only with respect to
clauses (ii) and (iii) below) exists at the time of receipt, the following Net
Offering Proceeds shall not be required to be so applied: (i) equity
contributions permitted under Section 8.8 to any Subsidiary Guarantor made by
any Borrower or any of their Subsidiaries; (ii) Net Offering Proceeds received
as a result of the exercise of any stock options exercised by or any Capital
Stock or Junior Subordinated Notes issued to any director, officer or employee
of Holdings or any of its Subsidiaries to the extent the proceeds excluded
pursuant to this clause (ii) do not exceed $5,000,000 in the aggregate for all
such exercises and issuances; (iii) Net Offering Proceeds of any Capital Stock
of Holdings issued as consideration in any Permitted Acquisition; and (iv) Net
Offering Proceeds received as a result of any Capital Stock or Junior
Subordinated Notes issued to any existing shareholder (other than a Person
identified in clause (ii) above) of Holdings as of the Closing Date (and any
Affiliate of such shareholder).

                  (f) Mandatory Prepayment Upon Incurrence of Indebtedness. On
the first Business Day after receipt thereof by Holdings and/or any of its
Subsidiaries after the Initial Borrowing Date, an amount equal to 100% of the
Net Offering Proceeds of the incurrence of Indebtedness (other than Indebtedness
relating to Junior Subordinated Notes) by Holdings and/or any of its
Subsidiaries (other than Indebtedness permitted to be incurred by Section 8.2)
shall be applied as a mandatory repayment of principal of the Term Loans as
provided in Section 4.5 in each case subject to modification of such application
as set forth in Section 4.5(d).

                  (g) Mandatory Prepayment Upon Recovery Event. Within ten (10)
days following each date on which Holdings or any of its Subsidiaries receives
any cash proceeds from any Recovery Event, an amount equal to 100% of the
proceeds of such Recovery Event (net of reasonable costs and taxes incurred in
connection with such Recovery Event) shall be applied as a mandatory repayment
of principal of the Loans as provided in Section 4.5 in each case subject to
modification of such application as set forth in Section 4.5(d), provided that
(1) so long as no Event of Default or Unmatured Event of Default then exists, if
the net proceeds from



                                       69


<PAGE>   71



any Recovery Event are less than $1,000,000, then no prepayment shall be
required pursuant to this Section 4.4(g), and (2) so long as no Event of Default
or Unmatured Event of Default then exists, with respect to any single or series
of related Recovery Events the net proceeds therefrom which are equal to or
greater than $1,000,000 but less than $5,000,000, such proceeds shall not be
required to be so applied on such date to the extent that (x) Borrowers have
delivered a certificate to the Agent on or prior to such date stating that such
proceeds shall be used to replace or restore any properties or assets in respect
of which such proceeds were paid within 180 days following the date of the
receipt of such proceeds (which certificate shall set forth the estimates of the
proceeds to be so expended) and (y) such proceeds are deposited in an escrow
account with Agent for the benefit of the Secured Parties (the "Recovery Event
Escrow Account"), from which escrow account amounts may be withdrawn only to
repay the Loans or to be used for the purposes described in clause (x) above,
provided, further, that (i) if the amount of such proceeds from any single or
series of related Recovery Events exceeds $2,000,000, then the entire amount and
not just the portion in excess of $2,000,000 shall be applied as a mandatory
repayment of Loans as provided above in this Section 4.4(g), (ii) if all or any
portion of such proceeds not required to be applied to the repayment of Loans
pursuant to the first proviso of this Section 4.4(g) are not so used (or
contractually committed to be used) within 180 days after the day of the receipt
of such proceeds, such remaining portion shall be applied on the last day of
such period as a mandatory repayment of principal of the Loans as provided in
this Section 4.4(g) and (iii) if all or any portion of such proceeds are not
required to be applied on the 180th day referred to in clause (ii) above because
such amount is contractually committed to be used and subsequent to such date
such contract is terminated or expires without such portion being so used, then
such remaining portion shall be applied on the date of such termination or
expiration as a mandatory repayment of principal of outstanding Loans as
provided in this Section 4.4(g).

                  (h) Mandatory Prepayment Upon Issuance of Senior Subordinated
Notes. On the date of receipt thereof by Borrowers, an amount equal to the cash
proceeds of the issuance of any Senior Subordinated Notes in accordance with
Section 8.2(e), after giving effect to the repayment in full of all indebtedness
and obligations owing under the Bridge Loan Documents and all fees, costs and
expenses incurred in connection with the issuance of the Senior Subordinated
Notes, shall be applied as a mandatory repayment of principal of the Term B
Loans as provided in Section 4.5 subject to modification as set forth in
Sections 4.5(c) and (d).

                  Section 4.5. Application of Prepayments.

                  (a) Prepayments. Except as expressly provided in this
Agreement, all prepayments of principal made by Borrowers pursuant to Section
4.4 (other than Section 4.4(h) and prepayments of Net Cash Proceeds for
Designated Asset Dispositions pursuant to Section 4.4(c)) shall be applied (i)
first to the payment of the unpaid principal amount of the Term Loans (with,
except as provided in the second succeeding sentence, the Term A Percentage of
such repayment to be applied as a repayment of Term A Loans, the Term B
Percentage of such repayment to be applied as a repayment of Term B Loans and
the Acquisition Percentage of such repayment to be applied as a repayment of
Acquisition Term Loans), and second to the payment of the then outstanding
balance of the Revolving Loans and the cash collateralization of LC Obligations
and Rollover LC Obligations; (ii) within each of the foregoing Loans, first to
the payment of Base Rate Loans and second to the payment of Eurodollar Loans;
and (iii) with respect to Eurodollar Loans, in such order as Borrowers shall
request (and in the absence of such


                                       70

<PAGE>   72


request, as Agent shall determine so as to minimize, if possible, any amounts
due under Section 3.5). Except as expressly provided in this Agreement, all
prepayments of principal made by Borrowers pursuant to Section 4.4(h) shall be
applied (i) to the payment of the unpaid principal amount of the Term B Loans
and (ii) first to the payment of Base Rate Loans and second to the payment of
Eurodollar Rate Loans, in such order as Borrowers shall request (and in the
absence of such request, as Agent shall determine so as to minimize, if
possible, any amounts due under Section 3.5). All prepayments of Acquisition
Loans with Net Cash Proceeds from Designated Asset Dispositions pursuant to
Section 4.4(c) shall be applied (i) to the payment of the unpaid principal
amount of the Acquisition Loans and (ii) first to the payment of Base Rate Loans
and second to the payment of Eurodollar Rate Loans, in such order as Borrowers
shall request (and in the absence of such request, as Agent shall determine so
as to minimize, if possible, any amounts due under Section 3.5). Each prepayment
of the Term Loans pursuant to Section 4.4(c), (d), (e), (f) and (g) shall be
applied first to the Term Loans based on the aggregate principal amount of the
unpaid Scheduled Term A Repayments, Scheduled Term B Repayments and Scheduled
Acquisition Repayments due within the twelve month period following the date of
such prepayment and shall be applied to such Scheduled Term A Repayments,
Scheduled Term B Repayments and Scheduled Acquisition Repayments in direct order
of maturity, and, thereafter, shall be allocated second to the Term Loans in
proportional amounts equal to the Term A Percentage, Term B Percentage and
Acquisition Percentage (in each case, after giving effect to the prepayments
made to the unpaid Scheduled Term A Repayments, Scheduled Term B Repayments and
Scheduled Acquisition Repayments due within such twelve month period as
specified above), as the case may be, of such remaining prepayment, if any and,
within each Term Loan, shall be applied to reduce the remaining Scheduled Term A
Repayments, Scheduled Term B Repayments and Scheduled Acquisition Repayments on
a pro rata basis (based upon the then remaining principal amount of such
Scheduled Term A Repayments, Scheduled Term B Repayments and Scheduled
Acquisition Repayments, respectively.) Any prepayment of the Acquisition
Revolving Loans and Working Capital Loans pursuant to this section shall be
allocated first to the Acquisition Revolving Loans until paid in full and second
to the Working Capital Loans. If any prepayment of Eurodollar Loans made
pursuant to a single Borrowing shall reduce the outstanding Loans made pursuant
to such Borrowing to an amount less than the Minimum Borrowing Amount, such
Borrowing shall immediately be converted into Base Rate Loans. All prepayments
shall include payment of accrued interest on the principal amount so prepaid,
shall be applied to the payment of interest before application to principal and
shall include amounts payable, if any, under Section 3.5.

                  (b) Payments. All regular installment payments of principal on
the Term Loans shall be applied (i) first to the payment of Base Rate Loans and
second to the payment of Eurodollar Loans and (ii) with respect to Eurodollar
Loans, in such order as Borrowers shall request (and in the absence of such
request, as Agent shall determine). All payments shall include payment of
accrued interest on the principal amount so paid, shall be applied to the
payment of interest before application to principal and shall include amounts
payable, if any, under Section 3.5.

                  (c) Term B Call Protection. Notwithstanding anything to the
contrary herein, in the event that any payment is received in respect of Term B
Loans prior to December 15, 2001 pursuant to Section 4.3 or 4.4(h), such
repayment shall be made at 101% of the principal amount




                                       71

<PAGE>   73


of the Term B Loans repaid and repayment of other Loans, if any, shall be
adjusted accordingly to allow such repayment.

                  (d) Waiver of Certain Prepayments by Term B Lenders.
Notwithstanding anything to the contrary contained in this Section 4.5 or
elsewhere in this Agreement (including, without limitation, in Section 12.1),
with respect to the amount of any prepayment described in Sections 4.3, 4.4(d),
(e), (f) and (g) that is allocated to the then outstanding Term B Loans (such
amounts, the "Waivable Prepayment"), Borrowers shall, not less than 3 nor more
than 20 Business Days prior to the date specified therein for such prepayment
(the "Mandatory Prepayment Date"), provide to each Term B Lender a written
notice (each, a "Prepayment Option Notice"), which shall refer to this Section
4.5(d) and shall (i) set forth the Waivable Prepayment and the portion thereof
that the applicable Term B Lender (each, a "Prepayment Lender") will be entitled
to receive if it accepts such mandatory prepayment in accordance with this
clause (i), (ii) request such Prepayment Lender to notify Agent in writing no
later than the Business Day prior to the Mandatory Prepayment Date of such
Prepayment Lender's acceptance or rejection (in each case, in whole and not in
part) of its share of the Waivable Prepayment and (iii) inform such Prepayment
Lender that failure by such Prepayment Lender to reject in writing its share of
the Prepayment Amount on or before the Business Day prior to the Mandatory
Prepayment Date shall be deemed an acceptance of such amount. Each Prepayment
Option Notice shall be given by telecopy, confirmed by hand delivery, overnight
courier service or registered or certified mail, in each case addressed as
provided in Section 12.3. On the Mandatory Prepayment Date, Borrowers shall
apply the aggregate amount necessary to prepay that portion of the Prepayment
Amount in respect of which such Prepayment Lenders have accepted prepayment as
described above (such Prepayment Lenders, the "Accepting Lenders") with the
remainder of the Waivable Prepayment applied to the Term A Loans and Acquisition
Term Loans in accordance with Section 4.5(a), as if all Term B Loans had been
paid in full.

                  Section 4.6.  Method and Place of Payment.

                  (a) Except as otherwise specifically provided herein, all
payments under this Agreement shall be made to Agent, for the ratable account of
the Lenders entitled thereto, not later than 1:00 P.M. (New York City time) on
the date when due and shall be made in immediately available funds in lawful
money of the United States of America and in each case to the account specified
therefor for Agent or if no account has been so specified at the Payment Office,
it being understood that with respect to payments in Dollars, written telex or
telecopy notice by Borrowers to Agent to make a payment from the funds in
Borrowers' account at the Payment Office shall constitute the making of such
payment to the extent of such funds held in such account. Agent will thereafter
cause to be distributed on the same day (if payment was actually received by
Agent prior to 1:00 P.M. (New York City time) on such day) like funds relating
to the payment of principal or interest or fees ratably to the Lenders entitled
to receive any such payment in accordance with the terms of this Agreement. If
and to the extent that any such distribution shall not be so made by Agent in
full on the same day (if payment was actually received by Agent prior to 1:00
P.M. (New York City time) on such day), Agent shall pay to each Lender its
ratable amount thereof and each such Lender shall be entitled to receive from
Agent, upon demand, interest on such amount at the overnight Federal Funds Rate
for each day from the date such amount is paid to Agent until the date Agent
pays such amount to such Lender.

<PAGE>   74


                  (b) Any payments under this Agreement which are made by
Borrowers later than 1:00 P.M. (New York City time) shall, for the purpose of
calculation of interest, be deemed to have been made on the next succeeding
Business Day. Whenever any payment to be made hereunder shall be stated to be
due on a day which is not a Business Day, the due date thereof shall be extended
to the next succeeding Business Day and, with respect to payments of principal,
interest shall be payable during such extension at the applicable rate in effect
immediately prior to such extension, except that with respect to Eurodollar
Loans, if such next succeeding Business Day is not in the same month as the date
on which such payment would otherwise be due hereunder or under any Note, the
due date with respect thereto shall be the next preceding applicable Business
Day.

                  Section 4.7.  Net Payments.

                  (a) All payments made by or on behalf of Borrowers hereunder
or under any Loan Document will be made without setoff, counterclaim or other
defense. Except as provided in Section 4.7(d), all payments hereunder and under
any of the Loan Documents (including, without limitation, payments on account of
principal and interest and fees) shall be made by or on behalf of Borrowers free
and clear of and without withholding for or on account of any present or future
tax, duty, levy, impost, assessment or other charge of whatever nature now or
hereafter imposed by any Governmental Authority, but excluding therefrom (i) a
tax imposed on the overall net income (including a franchise tax based on net
income) of the lending office of the Lender in respect of which the payment is
made by the jurisdiction in which the Lender is incorporated or organized or the
jurisdiction (or political subdivision or taxing authority thereof) in which its
lending office is located, (ii) in the case of any Lender that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) and
that does not comply with Section 4.7(d), any taxes imposed by the United States
by means of withholding at the source unless such withholding results from a
change in applicable law, treaty or regulations or the interpretation or
administration thereof (including, without limitation, any guideline or policy
not having the force of law) by any authority charged with the administration
thereof subsequent to the date such Lender becomes a Lender with respect to the
Loan or portion thereof affected by such change and (iii) any tax imposed on or
measured by the overall net income (including a franchise tax based on net
income, but excluding any taxes imposed by the United States by means of
withholding at the source) of a Lender or an office or branch thereof by the
United States of America or any political subdivision or taxing authority
thereof or therein (such tax or taxes, other than excluded tax or taxes, being
herein referred to as "Tax" or "Taxes"). If Borrowers are required by law to
make any deduction or withholding of any Taxes from any payment due hereunder or
under any of the Loan Documents, then the amount payable will be increased to
such amount which, after deduction from such increased amount of all such Taxes
required to be withheld or deducted therefrom, will not be less than the amount
due and payable hereunder had no such deduction or withholding been required.

                  (b) If Borrowers make any payment hereunder or under any of
the Loan Documents in respect of which it is required by law to make any
deduction or withholding of any Taxes, it shall pay the full amount to be
deducted or withheld to the relevant taxation or other authority within the time
allowed for such payment under applicable law and shall deliver to the Lenders
within 30 days after it has made such payment to the applicable authority a
receipt


                                       73


<PAGE>   75



issued by such authority evidencing the payment to such authority of all amounts
so required to be deducted or withheld from such payment.

                  (c) Without prejudice to the provisions of Section 4.7(a), if
any Lender, or Agent on its behalf, is required by law to make any payment on
account of Taxes on or in relation to any such received or receivable tax
hereunder or under any of the Loan Documents by such Lender, or Agent on its
behalf, or any liability for Tax in respect to any such payment is imposed,
levied or assessed against any Lender or Agent on its behalf, Borrowers (on a
joint and several basis) will promptly indemnify such person against such Tax
payment or liability, together with any interest, penalties and expenses
(including counsel fees and expenses) payable or incurred in connection
therewith, including any tax of any Lender arising by virtue of payments under
this Section 4.7(c), computed in a manner consistent with this Section 4.7(c). A
certificate (showing in reasonable detail the basis for such calculation) as to
the amount of such payment by such Lender, or Agent on its behalf, absent
manifest error, shall be final, conclusive and binding upon all parties hereto
for all purposes.

                  (d) Each Lender that is not a United States person (as such
term is defined in Section 7701(a)(30) of the Code) agrees to deliver to
Borrowers and Agent on or prior to the Initial Borrowing Date, or in the case of
a Lender that is an Assignee of an interest under this Agreement pursuant to
Section 3.7 or 12.8 (unless the respective Lender was already a Lender hereunder
immediately prior to such assignment), on the date of such assignment to such
Lender, together with any other certificate or statement of exemption required
under the Code to establish that such Lender is not subject to deduction or
withholding of United States federal income tax with respect to any payments to
such Lender, (i) two accurate and complete original signed copies of IRS Form
4224 or 1001 (or successor forms) certifying to such Lender's entitlement to a
complete exemption from United States withholding tax with respect to payments
to be made under this Agreement and under any Note, or (ii) if the Lender is not
a "bank" within the meaning of Section 881(c)(3)(A) of the Code, (x) a
certificate substantially in the form of Exhibit 4.7(d) (any such certificate, a
"Section 4.7(d)(ii) Certificate") and (y) two accurate and complete original
signed copies of IRS Form W-8 (or successor form) (including Form W-8BEN
(Certificate of Foreign Status of Beneficial Owner for United States Tax
Withholding) and Form W-8ECI (Certificate of Foreign Person's Claim for
Exemption From Withholding On Income Effectively Connected with the Conduct of a
Trade or Business in the United States)) certifying to such Lender's entitlement
to a complete exemption from United States withholding tax with respect to
payments of interest to be made under this Agreement and under any Note. In
addition, each Lender agrees that from time to time after the Initial Borrowing
Date, when a lapse in time or change in circumstances renders the previous
certification obsolete or inaccurate in any material respect, it will deliver to
Borrowers and Agent two new accurate and complete original signed copies of IRS
Form 4224 or 1001, or Form W-8 and a Section 4.7(d)(ii) Certificate, as the case
may be, and such other forms as may be required in order to confirm or establish
the entitlement of such Lender to a continued exemption from or reduction in
United States withholding Tax with respect to payments under this Agreement and
any Note, or it shall immediately notify Borrowers and Agent of its inability to
deliver any such form or certificate. Notwithstanding anything to the contrary
contained in Section 4.7(a), but subject to Section 12.8(c) and the immediately
succeeding sentence, (x) Borrowers shall be entitled, to the extent they are
required to do so by law, to deduct or withhold income or similar Taxes imposed
by the United States (or any political subdivision or taxing authority thereof
or therein) from interest,




                                       74

<PAGE>   76




fees or other amounts payable hereunder for the account of any Lender which is
not a United States person (as such term is defined in Section 7701(a)(30) of
the Code) for United States Federal income tax purposes to the extent that such
Lender has not provided to Borrowers IRS Forms that establish a complete
exemption from such deduction or withholding and (y) Borrowers shall be
obligated pursuant to Section 4.7(a) hereof to gross-up payments to be made to a
Lender in respect of income or similar Taxes imposed by the United States unless
(I) upon timely notice from the Borrowers, such Lender has not provided to
Borrowers the IRS Forms required to be provided to Borrowers pursuant to this
Section 4.7(d), or (II) in the case of a payment, other than interest, to a
Lender described in clause (ii) above, to the extent that such IRS Forms do not
establish a complete exemption from withholding of such Taxes. Notwithstanding
anything to the contrary contained in the preceding sentence or elsewhere in
this Section 4.7 and except as set forth in Section 12.8(c), Borrowers agree to
jointly and severally pay additional amounts and to indemnify each Lender in the
manner set forth in Section 4.7(a) (without regard to the identity of the
jurisdiction requiring the deduction or withholding) in respect of any amounts
deducted or withheld by it as described in the immediately preceding sentence as
a result of any changes after the Initial Borrowing Date in any applicable law,
treaty, governmental rule, regulation, guideline or order, or in the
interpretation thereof, relating to the deducting or withholding of income or
similar Taxes.

                  (e) Each Lender agrees that, as promptly as practicable after
it becomes aware of the occurrence of any event or the existence of any
condition that would cause Borrowers to make a payment in respect of any Taxes
to such Lender pursuant to Section 4.7(a) or a payment in indemnification for
any Taxes pursuant to Section 4.7(c), it will use reasonable efforts to make,
fund or maintain the Loan (or portion thereof) of such Lender with respect to
which the aforementioned payment is or would be made through another lending
office of such Lender if as a result thereof the additional amounts which would
otherwise be required to be paid by Borrowers in respect of such Loans (or
portions thereof) or participation in Letters of Credit pursuant to Section
4.7(a) or Section 4.7(c) would be materially reduced, and if, in the judgment of
such Lender, the making, funding or maintaining of such Loans or participation
in Letters of Credit (or portions thereof) through such other lending office
would not be otherwise disadvantageous to such Lender. Borrowers agree to
jointly and severally pay all reasonable expenses incurred by any Lender in
utilizing another lending office of such Lender pursuant to this Section 4.7(e).

                  (f) If Borrowers shall pay any Taxes pursuant to this Section
4.7 and any Lender at any time thereafter receives a refund of tax or credit
against its tax liabilities on account of such payment of Taxes, then such
Lender shall promptly pay to Borrowers the amount of such refund or credit.

                         REPRESENTATIONS AND WARRANTIES

          In order to induce the Lenders to enter into this Agreement and to

necessary power and authority to execute, deliver and perform the terms and
provisions of each


                                       89

corporate or other action to authorize the execution, delivery and performance
by it of each of such Documents. Each Credit Party has duly executed and

Contractual Obligation to which any Credit Party is a party or by which or any
of its property or assets is bound or to which it may be subject, (iii) will
violate any provision of any Organizational Document of any Credit Party or (iv)
require any approval of stockholders or any approval or consent of any Person

delivery and performance of the Transaction Documents, for immaterial violations
or conflicts, or failure to obtain any immaterial consent or approval.

                  Section 6.5. Financial Statements; Financial Condition;
Undisclosed Liabilities; Projections.

                  (a)  Financial Statements. (i) The consolidated balance sheets
of Holdings and its predecessors dated December 31, 1997, December 31, 1998,
September 30, 1999 and the related consolidated statements of operations, cash
flows and shareholders' equity of Holdings for the Fiscal Year or other period

furnished to the Lenders prior to the Closing Date which, in the case of the


                                       90

<PAGE>   92

December 31, 1997 and 1998 statements, have been examined by
PriceWaterhouseCoopers LLP, independent certified public accountants, who
delivered an unqualified opinion in respect thereto, present fairly in all
material respects, in accordance with GAAP (except, in the case of unaudited
financial statements, for the absence of footnotes and normal occurring year-end
audit adjustments), the financial condition and results of operations of
Holdings and its Subsidiaries for the periods referred to therein, (ii) the
consolidated balance sheets of LISN Holdings and its Subsidiaries dated December
31, 1996, December 31, 1997, December 31, 1998, June 30, 1999 and September 30,
1999 and the related statements of operations, cash flows and changes in
stockholders' equity of LISN Holdings and its Subsidiaries for the Fiscal Year
or other period ended on such dates, as the case may be, and copies of which
have hereto been furnished to the Lenders prior to the Closing Date which, in
the case of the December 31, 1996, December 31, 1997 and 1998 statements, have
been examined by PriceWaterhouseCoopers LLP, independent certified public
accountants, who delivered an unqualified opinion in respect thereto, present
fairly in all material respects, in accordance with GAAP (except, in the case of
unaudited financial statements, for the absence of footnotes and normal
occurring year-end audit adjustments), the financial condition and results of
operations of LISN Holdings and its Subsidiaries for the periods referred to
therein, the consolidated balance sheet of Arion, Inc. and its Subsidiaries
dated December 31, 1998 and the related statements of income, stockholders'
equity and cash flows of Arion, Inc. and its Subsidiaries for the fiscal year
ended on such date and copies of which have hereto been furnished to the Lenders
prior to the Closing Date, which have been examined by PriceWaterhouseCoopers
LLP, independent certified public accountants, who delivered an unqualified
opinion in respect thereto, present fairly in all material respects, in
accordance with GAAP, the financial condition and results of operations of
Arion, Inc. and its Subsidiaries for the period referred to therein and (iv) the
pro forma (after giving effect to the Transactions, the related financing
thereof and the other transactions contemplated hereby and thereby) consolidated
balance sheet of Holdings attached hereto as Schedule 6.5(a) (the "Pro Forma
Balance Sheet") presents fairly the consolidated financial condition of Holdings
and its Subsidiaries at the date of such balance sheet and presents a good faith
estimate of the pro forma consolidated financial condition of Borrowers and
their Subsidiaries (after giving effect to the Transactions, the related
financing thereof and the other transactions contemplated hereby and thereby) at
the date thereof. The Pro Forma Balance Sheet has been prepared in accordance
with GAAP consistently applied (except as may be indicated in the notes thereto)
subject to footnote disclosure and normal year-end audit adjustments. Since
December 31, 1998 there has been no material adverse change in the business,
financial condition, assets, liabilities or results of operations of Holdings
and its Subsidiaries taken as a whole.

                  (b)   Solvency. On and as of the Closing Date, after giving
effect to the Transactions and to all Indebtedness (including the Loans, the
Junior Subordinated Notes and the loans incurred under the Bridge Loan
Agreement) being incurred, and to be incurred (and the use of proceeds thereof),
and Liens created, and to be created, by the Credit Parties in connection with
the transactions contemplated hereby, with respect to each of Holdings and its
Subsidiaries (on a consolidated basis) and of each Borrower and its Subsidiaries
(on a consolidated basis) (i) the sum of the assets, at a fair valuation
(measured on a going concern basis), of each of Holdings and its Subsidiaries
(on a consolidated basis) and each Borrower and its Subsidiaries (on a
consolidated basis) will exceed its debts (taking into account the joint and
several nature of Borrowers' Obligations); (ii) neither Holdings and its
Subsidiaries (on a consolidated basis) nor each Borrower and its Subsidiaries
(on a consolidated basis) have incurred nor intend, nor



                                       91

<PAGE>   93
believe that they will, incur debts beyond its ability to pay such debts as
such debts mature in the ordinary cause of business; and (iii) each of Holdings
and its Subsidiaries (on a consolidated basis) and each Borrower and its
Subsidiaries (on a consolidated basis) will have sufficient capital with which
to conduct their business. For purposes of this Section 6.5(b) "debt" means any
liability on a claim, and "claim" means (y) any right to payment, whether or not
such a right is reduced to judgment, liquidated, unliquidated, fixed,
contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured,
or unsecured (including all obligations, if any, under any Plan or the
equivalent for unfunded past service liability, and any other unfunded medical
and death benefits) or (z) any right to an equitable remedy for breach of
performance if such breach gives rise to a payment, whether or not such right to
an equitable remedy is reduced to judgment, fixed, contingent, matured,
unmatured, disputed, undisputed, secured or unsecured.

                  (c)   No Undisclosed Liabilities. Except as fully reflected in
the financial statements and the notes related thereto delivered pursuant to
Section 6.5(a) or as reflected in the Pro Forma Balance Sheet or Schedule 6.5(c)
hereto and the Indebtedness incurred under this Agreement, the Junior
Subordinated Notes and the Bridge Loan Agreement, there were as of the Closing
Date (and after giving effect to the Transactions and the other transactions
contemplated hereby) no liabilities or obligations with respect to the Credit
Parties (whether absolute, accrued or contingent and whether or not due) which,
either individually or in aggregate, exceed $1,000,000. As of the Closing Date
(and after giving effect to the Transactions and the other transaction
contemplated hereby), neither Holdings nor any Borrower knows of any basis for
the assertion against any Credit Party of any liability or obligation that is
not fully reflected in the financial statements or the notes related thereto
delivered pursuant to Section 6.5(a), on Schedule 6.5(c) or on Schedule 6.5(d)
which, either individually or in the aggregate, exceed $1,000,000.

                  (d)   Indebtedness. Schedule 6.5(d) sets forth a true and
complete list of all Indebtedness (other than the Loans and the Letters of
Credit) of Holdings and its Subsidiaries as of the Closing Date and which is to
remain outstanding after giving effect to the Transactions (the "Indebtedness to
Remain Outstanding"), in each case showing the aggregate principal amount
thereof (and the aggregate amount of any undrawn commitments with respect
thereto) and the name of the respective obligor and any other entity which
directly or indirectly guaranteed such debt. No Indebtedness to Remain
Outstanding has been incurred in connection with, or in contemplation of, the
Transactions or the other transactions contemplated hereby. All Indebtedness of
Holdings, Borrowers and each Subsidiary to Agent or to the Lenders under the
Loan Documents constitutes indebtedness which is senior in priority of payment
to the Junior Subordinated Notes and the Bridge Loan Agreement.

                  (e)   Projections. On and as of the Closing Date, the
financial projections previously delivered to Agent and the Lenders by Borrower
and contained in that certain confidential information memorandum dated November
1999 (the "Projections") were prepared on a basis consistent with the financial
statements referred to in Section 6.5(a) and, at the time of the preparation
thereof, were based on good faith estimates and assumptions made by the
management of Holdings, and there are no statements or conclusions in any of the
Projections which were based upon or include information known to any Credit
Party to be misleading or which failed to take into account material information
regarding the matters reported therein. On the Closing Date, Holdings and each
Borrower believes that the Projections are reasonable and



                                       92

<PAGE>   94


attainable, it being understood that uncertainty is inherent in any forecasts or
projections and that no assurance can be given that the results set forth in the
Projections will actually be obtained.

                  Section 6.6. Litigation. There are no actions, suits or
proceedings pending or, to the best knowledge of Holdings or any Borrower,
threatened (i) with respect to any Document, (ii) with respect to any
Indebtedness or Capital Stock of Holdings or any of its Subsidiaries or (iii)
that could reasonably be expected to have a Material Adverse Effect.

                  Section 6.7. True and Complete Disclosure. All factual
information (taken as a whole) heretofore or contemporaneously furnished by or
on behalf of Holdings or any of its Subsidiaries in writing to any Lender
(including, without limitation, all information contained in the Documents)
(other than the Projections as to which Section 6.5(e) applies) for purposes of
or in connection with this Agreement or any transaction contemplated herein is,
and all other such factual information (taken as a whole) hereafter furnished by
or on behalf of Holdings or any of its Subsidiaries in writing to any Lender for
purposes of or in connection with this Agreement or any transaction contemplated
herein are and will be (and, solely with respect to any such information
furnished on behalf of Holdings or any Subsidiary by a third party, to the best
knowledge of Holdings and Borrowers after due inquiry are and will be) true and
accurate in all material respects on the date as of which such information is
dated or certified and not incomplete by omitting to state any fact necessary to
make such information (taken as a whole) not misleading in any material respect
at such time in light of the circumstances under which such information was
provided.

                  Section 6.8. Use of Proceeds; Margin Regulations.

                  (a)   Term Loan Proceeds. All proceeds of the Term Loans
incurred on the Initial Borrowing Date shall be used by Borrowers (i) to
refinance, in part, all of the indebtedness and obligations under the Existing
Credit Agreements, (ii) to finance the Reorganization, (iii) to pay fees and
expenses in connection with the Transactions, and (iv) for general corporate
purposes of Borrowers and their Subsidiaries.

                  (b)   Working Capital Loan Proceeds. All proceeds of the
Working Capital Loans incurred hereunder shall be used by Borrowers for ongoing
working capital needs, Capital Expenditures and general corporate purposes of
the Borrowers and their Subsidiaries (but excluding Permitted Acquisitions and
the repayment of Acquisition Loans).

                  (c)   Acquisition Revolving Loan Proceeds. All proceeds of the
Acquisition Revolving Loans incurred hereunder shall be used by Borrowers (i) to
finance Permitted Acquisitions and (ii) to pay fees and expenses in connection
with Permitted Acquisitions.

                  (d)   Margin Regulations. No part of the proceeds of any Loan
will be used to purchase or carry any margin stock, directly or indirectly, or
to extend credit for the purpose of purchasing or carrying any such margin stock
for the purpose of reducing or retiring any indebtedness which was originally
incurred to purchase or carry any margin security or for any other purpose which
might cause any of the loans or extensions of credit under this Agreement to be
considered a "purpose credit" within the meaning of Regulation T, U or X of the
Board.

                  Section 6.9. Taxes.

                  (a)   Tax Returns and Payments. Each of Holdings and each of
its Subsidiaries has timely filed or caused to be filed with the appropriate
taxing authority, all returns, statements, forms and reports for material taxes
(the "Returns") required to be filed by or with respect to the income,
properties or operations of Holdings and/or any of its Subsidiaries. The Returns
accurately reflect all liability for taxes of Holdings and its Subsidiaries for
the periods covered thereby. Each of Holdings and each of its Subsidiaries has
paid all material taxes payable by it before they have become delinquent other
than those contested in good faith and for which adequate reserves have been
established in conformity with GAAP. As of the Closing Date, there is no action,
suit, proceeding, investigation, audit, or claim pending or, to the knowledge of
Borrower, threatened by any authority regarding any taxes relating to Holdings
or any of its Subsidiaries other than as disclosed on Schedule 6.9 hereto. As of
the Closing Date, neither Holdings nor any of its Subsidiaries has entered into
an agreement or waiver or been requested to enter into an agreement or waiver
extending any statute of limitations relating to the payment or collection of
taxes of Holdings or any of its Subsidiaries, or is aware of any circumstances
that would cause the taxable years or other taxable periods of Holdings or any
of its Subsidiaries not to be subject to the normally applicable statute of
limitations. As of the Closing Date, neither Holdings nor any of its
Subsidiaries have provided, with respect to themselves or property held by them,
any consent under Section 341 of the Code. Neither Holdings nor any of its
Subsidiaries has incurred, or will incur, any material tax liability in
connection with the Transactions.

                  (b)   Tax Examinations. Except as set forth on Schedule 6.9
hereto, as of the Closing Date, the federal income tax returns on each of
Holdings and its Subsidiaries have been examined by the IRS (or closed by
applicable statutes) for any tax periods, and there are no other tax
examinations in progress. All deficiencies which have been asserted against
Holdings or any of its Subsidiaries as a result of such examinations have been
fully paid or finally settled or are being contested in good faith, and no issue
has been raised in any such examination which, by application or similar
principles, reasonably can be expected to result in an assertion of a deficiency
for any other year not so examined that has not been accrued on Holding's and
its Subsidiaries' or LISN Holdings' and its Subsidiaries audited financial
statements for its most recently ended Fiscal Year that would be required to be
so accrued in accordance with GAAP. Neither Holdings nor any of its Subsidiaries
has knowledge of any material federal income tax liability with respect to open
taxable years in excess of amounts accrued on such Person's financial statements
for its most recently ended Fiscal Year that would be required to be so accrued
in accordance with GAAP, nor does Holdings or any of its Subsidiaries anticipate
any further material tax liability with respect to such open taxable years taken
as a whole in excess of such accrued amounts.

                  Section 6.10. Compliance With ERISA. Each Plan is in all
material respects in compliance with ERISA and the Code; no Reportable Event
which could reasonably be expected to result in the termination of any Plan has
occurred with respect to a Plan; no Multiemployer Plan is insolvent or in
reorganization; the aggregate fair market value of the assets of each Plan
equals or exceeds the aggregate present value of the accrued benefits under such
Plan (using the actuarial funding assumptions then in effect for such Plan); no
Plan has an accumulated or waived funding deficiency, has permitted decreases in
its funding standard account or has



                                       94

<PAGE>   96


applied for an extension of any amortization period within the meaning of
Section 412 of the Code of Section 302 of ERISA; neither Holdings nor any of its
Subsidiaries nor any ERISA Affiliate has incurred any material liability to or
on account of a Plan pursuant to Section 409, 502(i), 502(d), 515, 4062, 4063,
4064, 4069, 4201 or 4204 of ERISA or Section 4971 or 4975 of the Code or is
expected to incur any material liability under any of the foregoing Sections
with respect to any Plan; no proceedings have been instituted to terminate any
Plan; no condition exists which presents a risk to Holdings or any of its
Subsidiaries or any ERISA Affiliate of incurring a material liability to or on
account of a Plan pursuant to the foregoing provisions of ERISA and the Code;
using actuarial assumptions and computation methods consistent with subpart 1 of
Subtitle E of Title IV of ERISA, Holdings and its Subsidiaries and its ERISA
Affiliates would not have any liability to all Plans which are Multiemployer
Plans in the event of a complete withdrawal therefrom, as of the close of the
most recent fiscal year of each such Plan ending prior to the date of any Credit
Event; no Lien imposed under the Code or ERISA on the assets of Holdings or any
of its Subsidiaries or any ERISA Affiliate exists or is likely to arise on
account of any Plan; and Holdings and its Subsidiaries do not maintain or
contribute to any employee welfare benefit plan (as defined in Section 3(1) of
ERISA) which provides benefits to retired employees (other than as required by
Section 601 of ERISA) or any employee pension benefit plan (as defined in
Section 3(2) of ERISA), except where any of the foregoing, either individually
or in the aggregate, could not reasonably be expected to have a Material Adverse
Effect.

                  Section 6.11. Security Documents.

                  (a)   Security Agreement Collateral. The provisions of the
Security Agreement are effective to create in favor of Collateral Agent for the
benefit of the Secured Creditors a legal, valid and enforceable security
interest in all right, title and interest of each Credit Party in the
Collateral, and the Security Agreement, together with the timely filings of Form
UCC-1 creates a fully perfected first lien on, and security interest in, all
right, title and interest of each Credit Party in all of the Collateral (other
than trademarks, patents and copyrights) described therein, subject to no other
Liens other than Permitted Liens. The recordation in the United States Patent
and Trademark Office and in the United States Copyright Office of grants of
security interests made pursuant to the Security Agreement, together with
filings on Form UCC-1 made pursuant to the Security Agreement, will be
effective, under Federal law, to perfect the security interest granted to Agent
in the registered trademarks, patents and copyrights covered by the Security
Agreement, and the filing of grants of security interests made pursuant to the
Security Agreement, with the United States Copyright Office together with
filings on Form UCC-1 made pursuant to the Security Agreement, will be effective
under Federal law to perfect the security interest granted to Collateral Agent
in the registered copyrights covered by the Security Agreement. Each Credit
Party has good and marketable title to, or rights in, all Security Agreement
Collateral, free and clear of all Liens except Permitted Liens.

                  (b)   Pledged Securities. The security interests created in
favor of Collateral Agent, as Pledgee for the benefit of the Secured Creditors
under the Pledge Agreement, constitute first perfected security interests in the
Pledged Securities, if any, subject to no security interests of any other
Person. No filings or recordings are required in order to perfect the security
interests created in the Pledged Securities under the Pledge Agreement.



                                       95
<PAGE>   97

(c) Real Estate Collateral. The Mortgages create, as security for the
obligations purported to be secured thereby, a valid and enforceable perfected
security interest in and Lien on all of the Mortgaged Properties (including,
without limitation, all fixtures and improvements relating to such Mortgaged
Properties and affixed or added thereto on or after the Closing Date in favor of
Collateral Agent (or such other trustee as may be named therein)) for the
benefit of the Secured Creditors, superior to and prior to the rights of all
third Persons (except that the security interest created in the Mortgaged
Properties may be subject to the Permitted Liens related thereto) and subject to
no other Liens (other than Liens permitted under Section 8.1). Schedule 6.11(c)
contains a true and complete list of each parcel of Real Property owned or
leased by Holdings and its Subsidiaries on the Closing Date, identifies which
Credit Party has an interest therein and the type of interest therein held by
such Credit Party. Each Credit Party will have good and marketable title to all
Mortgaged Properties of such Credit Party free and clear of all Liens except
those described in the first sentence of this Section 6.11(c).

                  Section 6.12. Documents.

Borrowers have heretofore delivered to Agent true, correct and complete copies
of the Documents entered into in connection with the Transactions on or prior to
the Closing Date. Holdings and Borrowers have, concurrently with the execution
and delivery of this Agreement, consummated the transactions contemplated by the
Documents to be consummated as of the Closing Date pursuant thereto, and the
Documents set forth the entire agreement among the parties thereto with respect
to the subject matter thereof. Except as set forth on Schedule 6.12 hereto, no
party to the Documents has waived the fulfillment of any material condition
precedent set forth therein to the consummation of the transactions contemplated
thereby, no party is in default or has failed to perform any of its material
obligations thereunder or under any instrument or document executed and
delivered in connection therewith.

                  (b)   Representations and Warranties in Documents. All
representations and warranties made by Holdings or any of its Subsidiaries or,
to the best knowledge of Holdings and Borrowers, made by any third party in the
Documents were true and correct in all material respects at the time as of which
such representations and warranties were made or deemed made and as of the
Initial Borrowing Date, provided that any representation or warranty which by

Real Property Encumbrances with respect to Real Property. Substantially all
items of material real and material personal property owned by, leased to or
used by each Borrower and each Subsidiary are in adequate operating condition
and repair, ordinary wear and tear excepted, are free and clear of any known
defects except such defects as do not substantially interfere with the continued
use thereof in the conduct of normal operations, and are able to serve the
function for which they are currently being used. The items of material real and
personal property owned by, leased to or used by each Borrower and each
Subsidiary constitute all of the assets used in the



                                       96

conduct of such Person's business as presently conducted, and neither this
Agreement nor any other Document, nor any transaction contemplated under any
such agreement, will affect any right, title or interest of any Borrower or any
Subsidiary in and to any of such assets in a manner that would have or is
reasonably likely to have a Material Adverse Effect. To the knowledge of
Holdings and Borrowers, there are no actual, threatened or alleged defaults with
respect to any material leases of real property under which any Borrower or any
Subsidiary is lessee or lessor which could reasonably be expected to have a
Material Adverse Effect. Holdings and each Subsidiary have granted mortgages to
secure the Obligations on all parcels of real estate material to the operations
of Holdings and such Subsidiaries.

Transaction, no authorized but unissued or treasury shares of Capital Stock of
Holdings or any Borrower are subject to any option, warrant, right to call or
commitment of any kind or character, except as expressly set forth on Schedule
6.14. As of the Closing Date and after giving effect to the Transactions,
neither Holdings nor any Borrower has any outstanding stock or securities
convertible into or exchangeable for any shares of its Capital Stock, or any
rights issued to any Person (either preemptive or other) to subscribe for or to
purchase, or any options for the purchase of, or any agreements providing for
the issuance (contingent or otherwise) of, or any calls, commitments or claims
of any character relating to any of its Capital Stock or any stock or securities
convertible into or exchangeable for any of its Capital Stock other than as
expressly set forth on Schedule 6.14. As of the Closing Date, except as
disclosed on Schedule 6.14, neither Holdings nor any Borrower is subject to any
obligation (contingent or otherwise) to repurchase or otherwise acquire or
retire any shares of its Capital Stock or any convertible securities, rights or
options of the type described in the preceding sentence.

         of a voluntary act of Borrowers or the applicable Subsidiary; and

                  Section 7.5. Payment of Obligations. Holdings will, and will
cause each of its Subsidiaries to, pay or discharge or otherwise satisfy at
maturity or, to the extent permitted hereby, prior to maturity or before they
become delinquent, as the case may be:

                  (i)   all taxes, assessments and governmental charges or
         levies imposed upon any of them or upon any of their income or profits
         or any of their respective properties or assets prior to the date on
         which penalties attach thereto; and

                  (ii)  all lawful claims prior to the time they become a Lien
         upon any of their respective properties or assets;


                                      104

<PAGE>   106


provided, however, that neither Holdings nor any of its Subsidiaries shall be
required to pay or discharge any such tax, assessment, charge, levy or claim
while the same is being contested by it in good faith and by appropriate
proceedings diligently pursued so long as Holdings or such Subsidiary, as the
case may be, shall have set aside on its books adequate reserves in accordance
with GAAP (segregated to the extent required by GAAP) with respect thereto and
title to any material properties or assets is not jeopardized in any material
respect.

                  Section 7.6. Inspection of Property, Books and Records.
Holdings will, and will cause each of its Subsidiaries to, keep, or cause to be
kept adequate records and books of account, in which complete entries are to be
made reflecting its and their business and financial transactions, such entries
to be made in accordance with sound accounting principles consistently applied
and Holdings will permit, and cause each of its Subsidiaries to permit, Agent
and/or its designated representatives, at any reasonable time during normal
business hours, and from time to time at the reasonable request of Agent made to
Borrowers and upon reasonable prior written notice, to visit and inspect its and
their respective properties, to examine and make copies of and take abstracts
from its and their respective records and books of account (other than materials
protected by attorney-client privilege the disclosure or inspection of which,
based on a written opinion of counsel to Borrowers reasonably acceptable to
Agent, would waive such privilege), (provided that so long as no Event of
Default or Unmatured Event of Default exists and is continuing, Borrowers shall
not be obligated to pay for more than one visit and inspection by Agent per
Fiscal Year, provided, further, that during the continuance of an Event of
Default or Unmatured Event of Default all visits and inspections shall be at the
expense of Borrowers) and to discuss its and their respective affairs, finances
and accounts with its and their respective principal officers, directors and,
with prior written notice to Borrowers, independent public accountants (and by
this provision Holdings and Borrowers authorize such accountants to discuss with
Agent and/or the Lenders and such representatives the affairs, finances and
accounts of Holdings and its Subsidiaries so long as Holdings, Borrowers and
their officers and representatives are afforded the reasonable opportunity to
attend or participate in any such discussion).

                  Section 7.7. ERISA. Holdings will, and will cause each of its
Subsidiaries to, (i) as soon as practicable and in any event within ten (10)
Business Days after a Responsible Officer of Holdings or any of its Subsidiaries
or ERISA Affiliates knows or has reason to know that a Reportable Event has
occurred with respect to any Plan (whether or not the requirement for notice of
such Reportable Event has been waived by the PBGC), deliver, or cause such ERISA
Affiliate to deliver, to Agent a certificate on behalf of Holdings or such
Subsidiary or ERISA Affiliate of a Responsible Officer of Holdings or such
Subsidiary or ERISA Affiliate, as the case may be, setting forth the details of
such Reportable Event and the action, if any, which Holdings or such Subsidiary
or ERISA Affiliate is required or proposes to take, together with any notices
required or proposed to be given; (ii) upon the reasonable request of any Lender
made from time to time, deliver, or cause each ERISA Affiliate to deliver, to
each Lender a copy of the most recent actuarial report and annual report
completed with respect to any Plan; (iii) as soon as possible and in any event
within ten (10) Business Days after a Responsible Officer of Holdings or any of
its Subsidiaries or ERISA Affiliates knows or has reason to know that any of the
following have occurred or is reasonably likely to occur with respect to any
Plan: (A) such Plan has been or may be terminated, reorganized, petitioned or
declared insolvent under Title IV of ERISA, (B) the Plan Sponsor intends to
terminate such Plan, (C) the PBGC has instituted or will



                                      105

institute proceedings under Section 515 of ERISA to collect a delinquent
contribution to such Plan or under Section 4042 of ERISA to terminate such Plan,
(D) that an accumulated funding deficiency has been incurred or that on
application may be or has been made to the Secretary of the Treasury for a
waiver or modification of the minimum funding standard (including any required
installment payments) or on extension of any amortization period under Section
412 of the Code, (E) that Holdings, or any Subsidiary of Holdings, or any ERISA
Affiliate will or may incur any liability (including, but not limited to,
contingent or secondary liability) to or on account of the termination of or
withdrawal from a Plan under Section 401(a)(29), 4971, 4975 or 4980 of the Code
or Section 409 or 502(1) of ERISA, or (F) Holdings or any Subsidiary of Holdings
has or may incur any liability under any employee welfare benefit plan (within
the meaning of Section 3(1) of ERISA) that provides benefits to retired
employees (other than as required by Section 601 of ERISA) or any employee
pension benefit plans (as defined in Section 3(2) of ERISA), deliver, or cause
such ERISA Affiliate to deliver, to Agent a written notice thereof; and (iv) as
soon as possible and in any event within thirty days after Holdings or any of
its Subsidiaries or ERISA Affiliates knows or has reason to know that any of
them has incurred a complete withdrawal or partial withdrawal (within the
meaning of Sections 4203 and 4205, respectively, of ERISA) from any
Multiemployer Plan, deliver, or cause such ERISA Affiliate to deliver, to Agent
a written notice thereof. For purposes of this Section 7.7, Holdings and
Borrowers shall be deemed to have knowledge of all facts known by the Plan
Administrator of any Plan of which Holdings or Borrowers is the Plan Sponsor,
and each Subsidiary and ERISA Affiliate of Holdings shall be deemed to have
knowledge of all facts known by the Plan Administrator of any Plan of which such
Subsidiary or such ERISA Affiliate, respectively, is a Plan Sponsor. In addition
to its other obligations set forth in this Article VII, each of Holdings and
Borrowers shall, and shall cause each of its Subsidiaries and ERISA Affiliates
to:

                  (A) provide Agent with prompt written notice, with respect to
         any Plan, of any failure to satisfy the minimum funding standard
         requirements of Section 412 of the Code or section 302 of ERISA, which
         failure to so satisfy exceeds $5,000,000,

                  (B) furnish to Agent, promptly after delivery of the same to
         the PBGC, a copy of any delinquency notice pursuant to Section
         412(n)(4) of the Code or Section 302(f)(4) of ERISA,

                  (C) correct any such failure to satisfy funding requirements
         or delinquency referred to in the foregoing clauses (A) and (B) within
         ninety (90) days after the occurrence thereof, except where the failure
         to so satisfy would not reasonably be expected to have a Material
         Adverse Effect;

                  (D) comply in good faith with the requirements set forth in
         Section 4980(B) of the Code and with Sections 601(a) and 606 of ERISA;

                  (E) at the request of any Lender, deliver to such Lender (and

         each Plan required to be filed with the Internal Revenue Service; and

                  (F) at the request of any Lender, deliver to such Lender (and
         a copy to Agent) copies of the annual reports and notices received by
         Holdings or any Subsidiary or any

         ERISA Affiliate with respect to any Plan or Foreign Pension Plan no
         later than ten (10) Business Days after the date of such request.

                  Section 7.8. Maintenance of Property, Insurance. Holdings
will, and will cause each of its Subsidiaries to, (i) keep all material property
(including, but not limited to, equipment) used in its business in good working
order and condition, normal wear and tear and damage by casualty excepted, and
subject to Section 8.4(b), (ii) maintain insurance with respect to its
properties and business against loss or damage of the kinds customarily insured
against by Persons engaged in the same or similar business, of such types and in
such amounts as are customarily carried under similar circumstances by such
other Persons, such insurance shall be maintained with financially sound and
reputable insurers, except that a portion of such insurance program (not to
exceed that which is customary in the case of companies engaged in the same or
similar business or having similar properties similarly situated) may be
effected through self-insurance, provided adequate reserves therefor, in
accordance with GAAP, are maintained, and (iii) furnish to Agent, on the Closing
Date and on each anniversary thereof, certificates of insurance as to the
insurance carried. All insurance policies or certificates (or certified copies
thereof) with respect to such insurance (A) shall be endorsed to the Agent's
reasonable satisfaction for the benefit of the Agent and Lenders (including,
without limitation, by naming Agent as loss payee or additional insured, as
appropriate); and (B) shall state that such insurance policy shall not be
cancelled or revised without thirty days' prior to written notice thereof by the
insurer to the Agent. At any time that insurance at levels described in Schedule
7.8 is not being maintained by Holdings or any of its Subsidiaries, Borrowers
will notify the Lenders in writing within five Business Days thereof and, if
thereafter notified by Agent or the Required Lenders to do so, Borrowers or any
such Subsidiary, as the case may be, shall obtain insurance at such levels at
least equal to those set forth on Schedule 7.8. The provisions of this Section
7.8 shall be deemed to be supplemental to, but not duplicative of, the
provisions of any of the Security Documents that require the maintenance of
insurance.

                  Section 7.9. Environmental Laws.

                  (a)   Holdings will, and will cause each of its Subsidiaries
to, comply with, and cause its Subsidiaries to comply with, and, in each case
take reasonable steps to ensure compliance by all tenants and subtenants, if
any, with, all applicable Environmental Laws and obtain and comply in all
material respects with and maintain, and take reasonable steps to ensure that
all tenants and subtenants obtain and comply in all material respects with and
maintain, any and all licenses, approvals, notifications, registrations or
permits required by applicable Environmental Law except to the extent that in
the case of any of the foregoing, failure to do so would not reasonably be
expected to have a Material Adverse Effect;

                  (b)   Holdings will, and will cause each of its Subsidiaries
to, conduct and complete all investigations, studies, sampling and testing, and
all remedial, removal and other actions required under Environmental Laws and
promptly comply in all material respects with all lawful orders, directives and
information requests of all Governmental Authorities regarding Environmental
Laws except to the extent that any of the same are being contested in good faith
by appropriate proceedings and the pendency of such proceedings would not
reasonably be expected to have a Material Adverse Effect; and



                                      107

<PAGE>   109


                  (c)   Borrowers agree to jointly and severally defend,
indemnify and hold harmless Agent and the Lenders, and their respective
employees, agents, officers, trustees and directors, from and against any and
all claims, demands, penalties, fines, liabilities, settlements, damages, costs
and expenses of whatever kind or nature known or unknown, contingent or
otherwise, arising out of, or in any way relating to the violation of,
noncompliance with or liability under, any Environmental Law applicable to the
operations of Holdings, any of its Subsidiaries or their respective properties,
or any orders, requirements or demands of Governmental Authorities related
thereto, including, without limitation, reasonable attorneys' and consultants'
fees, investigation and laboratory fees, costs arising from any Remedial Action,
court costs and litigation expenses, except to the extent that any of the
foregoing resulted primarily from the gross negligence, bad faith or willful
misconduct of the party seeking indemnification therefor. The agreements in this
Section 7.9(c) shall survive the termination of this Agreement and the repayment
of the Notes and all other Obligations.

                  Section 7.10. Interest Rate Protection. Borrowers will, no
later than ninety (90) days following the Closing Date, enter into and maintain
arrangements reasonably acceptable to Agent which have the effect of
establishing a fixed or maximum interest rate acceptable to Agent and the
Required Lenders for an aggregate notional principal amount of Indebtedness
equal to at least $110,000,000 for a period of at least three (3) years.

                  Section 7.11. Use of Proceeds. Borrowers will use all proceeds
of the Loans as provided in Section 6.8.

                  Section 7.12. Additional Security; Further Assurances.

                  (a)   Agreement to Grant Additional Security. Promptly, and in
any event within 30 days after the acquisition by Holdings, any Borrower or any
Subsidiary of assets or real or personal property that would have constituted
Collateral on the Closing Date and investments of the type that would have
constituted Collateral on the Closing Date (the "Additional Collateral"),
Holdings and Borrowers will take, or will cause their Subsidiaries to take, all
necessary action, including (i) the filing of appropriate financing statements
under the provisions of the UCC, applicable domestic or local laws, rules or
regulations in each of the offices where such filing is necessary or appropriate
and (ii) with respect to owned real property, the execution of a mortgage, the
obtaining of Mortgage Policies, title surveys and real estate appraisals (or
with respect to material leased real property, Landlord Consents) satisfying all
Requirements of Law, to grant Collateral Agent a perfected Lien in such
Collateral pursuant to and to the full extent required by the Security Documents
and this Agreement.

                  (b)   Additional Subsidiary Guarantors. Holdings and each
Borrower agree to cause each new Domestic Subsidiary established or created in
accordance with Section 8.16 (a "New Domestic Subsidiary") to execute and
deliver the Subsidiary Guaranty or such other guaranty of all Obligations and
all obligations under Interest Rate Agreements and Other Hedging Agreements in
form and substance reasonably satisfactory to Agent.

                  (c)   Pledge of New Subsidiary Stock. Holdings and Borrowers
agree to pledge, or to cause their Subsidiaries to pledge, (i) all of the
Capital Stock of each new Domestic Subsidiary and (ii) 65% of all Capital Stock
of each new direct Foreign Subsidiary established or



                                      108

<PAGE>   110


created to Collateral Agent for the benefit of the Secured Creditors pursuant to
the Pledge Agreement.

                  (d)   Grant of Security by New Domestic Subsidiaries. Holdings
and Borrowers will cause each new Domestic Subsidiary established or created in
accordance with Section 8.16 and which is required to execute and deliver the
Subsidiary Guaranty pursuant to Section 7.12(b) to grant to Collateral Agent a
first priority Lien on all property (tangible and intangible) of such Subsidiary
upon terms substantially similar to those set forth in the Security Documents as
appropriate, and reasonably satisfactory in form and substance to Agent.
Holdings and Borrowers shall cause each Subsidiary, at its own expense, to
execute, acknowledge and deliver, or cause the execution, acknowledgment and
delivery of, and thereafter register, file or record in any appropriate
governmental office, any document or instrument reasonably deemed by Agent to be
necessary or desirable for the creation and perfection of the foregoing Liens.
Holdings and Borrowers will cause each of its newly established Subsidiaries to
take all actions reasonably requested by Agent (including, without limitation,
the filing of UCC-1's) in connection with the granting of such security
interests.

                  (e)   Documentation for Additional Security. The security
interests required to be granted pursuant to this Section 7.12 shall be granted
pursuant to such security documentation (which shall be substantially similar to
the Security Documents already executed and delivered by the Credit Parties on
the Closing Date) reasonably satisfactory in form and substance to Agent and
shall constitute valid and enforceable perfected security interests prior to the
rights of all third Persons and subject to no other Liens except Permitted
Liens. The Additional Security Documents and other instruments related thereto
shall be duly recorded or filed in such manner and in such places and at such
times as are required by law to establish, perfect, preserve and protect the
Liens, in favor of Collateral Agent for the benefit of the Secured Creditors,
required to be granted pursuant to the Additional Security Document and, all
taxes, fees and other charges payable in connection therewith shall be paid in
full by Borrowers. At the time of the execution and delivery of the Additional
Security Documents, Holdings and Borrowers shall cause to be delivered to the
Collateral Agent such agreements, certificates, customary opinions of counsel,
Mortgage Policies and other related documents as may be reasonably requested by
Agent to assure themselves that this Section 7.12 has been complied with.

                  (f)   Foreign Subsidiaries Security. If following a change in
the relevant sections of the Code or the regulations, rules, rulings, notices or
other official pronouncements issued or promulgated thereunder, counsel for
Borrowers reasonably acceptable to Agent does not within 30 days after a request
from Agent or the Required Lenders deliver evidence, in form and substance
reasonably satisfactory to Agent, with respect to any Foreign Subsidiary which
has not already had all of its stock pledged pursuant to the Pledge Agreement
that a pledge of 66-2/3% or more (in the case of any direct Foreign Subsidiary)
or all (in the case of any indirect Foreign Subsidiary) of the total combined
voting power of all classes of capital stock of such Foreign Subsidiary entitled
to vote, would cause the undistributed earnings of such Foreign Subsidiary as
determined for Federal income tax purposes to be treated as a deemed dividend to
such Foreign Subsidiary's United States parent for Federal income tax purposes,
then that portion of such Foreign Subsidiary's outstanding capital stock not
theretofore pledged pursuant to the Pledge Agreement shall be pledge to the
Collateral Agent for the benefit of the Secured Creditors pursuant to the Pledge
Agreement (or another pledge agreement in substantially similar form, if



                                      109

<PAGE>   111

needed), to the extent that entering into such Pledge Agreement is permitted by
the laws of the respective foreign jurisdiction and with all documents delivered
pursuant to this Section 7.12 to be in form and substance reasonably
satisfactory to Agent.

                  Section 7.13. End of Fiscal Years; Fiscal Quarters. Holdings
will cause each of its and its Subsidiaries' annual accounting reporting periods
to end on the Friday nearest December 31 of each year (each a "Fiscal Year"),
with quarterly accounting reporting periods ending on the Friday nearest March
31, June 30, September 30 and December 31 of each Fiscal Year (each a "Fiscal
Quarter").

                  Section 7.14. Y2K. Holdings and Borrowers shall take all
actions reasonably necessary and commit adequate resources to assure that its
computer-based and other systems (and those of all Subsidiaries) are able to
effectively process dates, including dates before, on and after January 1, 2000,
without experiencing any Y2K Problem that could reasonably be expected to have a
Material Adverse Effect. At the reasonable request of Agent, Holdings and
Borrowers will provide the Lenders with assurances and substantiations
(including, but not limited to, the results of internal or external audit
reports prepared in the ordinary course of business) reasonably acceptable to
the Lenders as to the capability of Holdings, Borrowers and their Subsidiaries
to conduct its and their businesses and operations before, on and after January
1, 2000 without experiencing a Y2K Problem which would reasonably be expected to
have a Material Adverse Effect.

                  Section 7.15. Vanke Redemption. Holdings will cause LISN
Holdings to consummate the Vanke Redemption on or prior to January 3, 2000
pursuant to Section 5.7 of the LISN Recapitalization Agreement as in effect on
the Closing Date, and cause all of the Vanke Shares to be permanently cancelled
such that the shares of LISN Holdings common stock delivered to the Collateral
Agent on the Closing Date and pledged under the Pledge Agreement shall
constitute all of the issued and outstanding shares of Capital Stock of LISN
Holdings from and after the consummation of the Vanke Redemption.

                  Section 7.16. Ownership of Subsidiaries. Holdings will at all
times prior to the LISN Mergers directly own 100% of the outstanding Capital
Stock of each of LISN Holdings (except solely with respect to the Vanke Shares
prior to the consummation at the Vanke Redemption) and NATG, and LISN Holdings
will at all times prior to the LISN Mergers directly own 100% of the outstanding
Capital Stock of LISN. Holdings will at all times after the LISN Mergers
directly own 100% of the outstanding Capital Stock of NATG. Borrowers will
directly or indirectly own 100% of the Capital Stock of each other Subsidiary of
Holdings.

                  Section 7.17. LISN Mergers. Holdings will effect and will
cause its applicable Subsidiaries to effect the LISN Mergers prior to January
30, 2000.

                  Section 7.18. Waiver to Existing Turnkey Agreements. Promptly,
and in any event within thirty (30) days following the Closing Date, Holdings
and Borrowers will begin to use their commercially reasonable efforts to obtain
executed waivers, with terms and conditions reasonably satisfactory to Agent, to
the existing turnkey agreements with TCI and its Affiliates to permit the Liens
created by the Loan Documents with respect to the property secured by such
turnkey agreements.

                               NEGATIVE COVENANTS

                  Holdings and Borrowers hereby covenant and agree that, so long
as any of the Commitments remain in effect or any Loan, LC Obligation or
Rollover LC Obligation remains outstanding and unpaid or any other amount is
owing to any Lender or Agent hereunder (but excluding any unasserted contingent
and indemnification obligations which by their terms expressly survive the
termination hereof):

Section 8.1. Liens. Holdings will not, and will not permit any of its
Subsidiaries to (i) create, incur, assume or suffer to exist or agree to create,
incur or assume any Lien in, upon or with respect to any of Holdings' or any of
its Subsidiaries' properties or assets (including, without limitation, any
securities or debt instruments of any of its Subsidiaries), whether now owned or
hereafter acquired, or assign or otherwise convey any right to receive income to
secure any obligation; (ii) take, cause or permit to be taken or cause any
action to be taken, which could create a Lien (other than a Lien permitted under
this Section), or suffer to exist any Lien (other than a Lien permitted under
this Section), on the Capital Stock of any Borrower or any Subsidiary of
Holdings or any Borrower which would require the sharing of an interest in such
capital stock with any Person; or (iii) enter into or assume any agreement
containing a negative pledge which would require a sharing of an interest in any
Collateral or any Mortgaged Property or prohibits or limits the grant of any
such interest, except for the following Liens (herein referred to as "Permitted
Liens"):

                  (a) Liens created by the Loan Documents or permitted by the
Security Documents;

                  (b) Customary Permitted Liens;

                  (c) Liens existing on the Closing Date and listed on Schedule
8.1(c) hereto securing Indebtedness to Remain Outstanding which is listed on
Schedule 6.5(d) hereto;

                  (d) Liens in favor of TCI or any of its Affiliates securing
advances made to any Borrower or any of its Subsidiaries pursuant to turnkey
agreements entered into in the ordinary course of business with TCI or any of
its Affiliates, provided that (i) such Liens shall only attach to property
(including proceeds thereof) which is purchased by the applicable advance and
shall automatically terminate when the applicable advance has been fully paid,
and (ii) Liens created by the Loan Documents in favor of the Collateral Agent
shall not be prohibited by any such turnkey agreement entered into after the
Closing Date;

                  (e) Liens relating solely to assets to be sold in any Asset
Disposition as permitted under Section 8.6(e); and

                  (f) additional Liens incurred by Borrowers and their
Subsidiaries which do not secure Indebtedness for money borrowed so long as the
value of the property subject to such Liens, and the Indebtedness and other
obligations secured thereby, do not exceed $3,000,000.

                  If requested by a lender of Purchase Money Indebtedness in
connection with an extension of credit to any Borrower or any Subsidiary which
is otherwise permitted by this

                                      111

Agreement, any lien or security interest of Agent or Collateral Agent for the
benefit of the Lenders in or upon the asset(s) being acquired by such Borrower
or Subsidiary and financed by such lender of Purchase Money Indebtedness may be
expressly subordinated to the lien or security interest therein of such lender
of Purchase Money Indebtedness on terms and conditions reasonably acceptable to
Agent and such lender of Purchase Money Indebtedness, which terms may include an
agreement by Agent or Collateral Agent not to foreclose upon the asset(s) being
financed by the lender of Purchase Money Indebtedness without the prior written
consent of such lender of Purchase Money Indebtedness, and the Lenders hereby
severally authorize Agent and Collateral Agent to enter into such an agreement.

                  Section 8.2. Indebtedness. Holdings will not, and will not
permit any of its Subsidiaries to, incur, create, assume directly or indirectly,
or suffer to exist any Indebtedness except:

                  (a) Indebtedness incurred pursuant to this Agreement and the
other Loan Documents;

                  (b) unsecured Indebtedness of Holdings evidenced by the Junior

Junior Subordinated Notes issued after the Closing Date to existing stockholders
of Holdings as of the Closing Date and their affiliates and/or to managers,

of which are used solely as consideration paid in connection with any Permitted
Acquisition, or issued to any seller pursuant to a Permitted Acquisition,
provided that (i) no Event of Default or Unmatured Event of Default exists at
the time of issuance thereof or will result therefrom, (ii) the principal amount

exceed thirty-eight percent (38%) of the total equity contribution (including
such Junior Subordinated Notes) being made by such Orius Holder at the time of
issuance thereof, and (iii) the aggregate principal amount of all Junior
Subordinated Notes issued after the Closing Date pursuant to this clause (c)
shall not exceed $25,000,000, as reduced by any repayment of principal thereof;

Borrower or such Subsidiary as terms that would be obtainable at the time for a

any of its Subsidiaries, as the case may be, in any material respect than the
original agreement as in effect on the Closing Date; (C) any issuance of
securities or other payments, awards or grants in cash, securities or otherwise
pursuant to, or the funding of, employment arrangements, stock options and stock

shall be approved by the board of directors of Holdings or such Subsidiary, as
the case may be, such approval to be evidenced by a resolution stating that such
board of directors has determined that such transaction complies with the
foregoing provisions. If Holdings or any of its Subsidiaries enters into an
affiliate transaction (or a series of related affiliate transactions related to
a common plan) that involves an aggregate fair market value of more than
$10,000,000, Holdings or such Subsidiary, as the case may be, shall, prior to
the consummation thereof, obtain a favorable opinion as to the fairness of such
transaction or series of related transactions to Holdings or the relevant
Subsidiary, as the case may be, from a financial point of view, from an
independent financial advisor and file the same with the Agent.

Notwithstanding the foregoing, LISN Holdings may engage in those activities that
are incidental to (A) the maintenance of its corporate existence in compliance

                  Section 8.13. Fiscal Year. Holdings will not, and will not
permit any of its Subsidiaries to, change the Fiscal Year of Holdings or its
Subsidiaries.

                  Section 8.14. Limitation on Voluntary Payments and Certain
Modifications. Holdings will not, and will not permit any of its Subsidiaries

entered into by it, with respect to its Capital Stock (including any
shareholders' agreement), or enter into any new agreement with respect to its
Capital Stock which in any way could be materially adverse to the interests of
the Lenders;

                  (c) amend, modify or grant any waiver with respect to any
Junior Subordinated Document, Seller Subordinated Note, Bridge Loan Document (it
being understood and agreed that the execution and delivery of the "Senior
Subordinated Indenture" as such term is defined in the Bridge Loan Agreement
shall not be deemed to be an amendment or modification of the Bridge Loan
Documents) or Senior Subordinated Document;

                  (d) amend, modify or grant any waiver with respect to any
Transaction Document, except in any case for changes thereto which do not

permit to be made any change in accounting policies affecting the presentation
of financial statements or reporting practices from those employed by it on the
Closing Date, unless (i) such change is either (A) required by GAAP or (B)
permitted by GAAP so long as such permitted change has no material impact on the
presentation of financial statements and has no impact on the calculation of the
financial covenants set forth in Article IX or in the definition of Excess Cash
Flow, (ii) such change is disclosed to the Lenders through Agent or otherwise
and (iii) relevant prior financial statements that are affected by such change
are restated (in form and detail reasonably satisfactory to Agent) as may be
required by GAAP to show comparative results. If any changes in GAAP or the
application thereof from that used in the preparation of the financial
statements referred to in Section 6.5(a) hereof occur after the Closing Date and
such changes

                                      123
<PAGE>   125

result in, in the sole judgment of Agent, a meaningful change in the calculation
of any financial covenants or restrictions set forth in this Agreement, then the
parties hereto agree to enter into and diligently pursue negotiations in order
to amend such financial covenants and restrictions so as to equitably reflect
such changes, with the desired result that the criteria for evaluating the
financial condition and results of operations of Holdings and its Subsidiaries
shall be the same after such changes as if such changes had not been made.

of any such new Subsidiary is in compliance with Section 8.8(h) (with the
transfer of any assets constituting an Investment under Section 8.8(h)), (ii)
100% of the Capital Stock of such Subsidiary is upon the creation, establishment
or acquisition of any such new Subsidiary pledged and delivered to the
Collateral Agent for the benefit of the Secured Creditors under the Pledge
Agreement and (iii) upon the creation, establishment or acquisition of any such
new Domestic Subsidiary, such Subsidiary executes the Additional Security
Documents and guaranty required to be executed by it in accordance with Section
7.12.

                  Section 8.17. Powers of Attorney. Holdings will not, and will

amount of Capital Expenditures permitted to be made by Borrowers and their
Subsidiaries pursuant to clause (a) above in any fiscal year (before giving
effect to any increase in such permitted expenditure amount pursuant to this
clause (b)) is greater than the amount of such Capital Expenditures made by

days (or committed to be paid within such 180 days so long as such replacement
or restoration is made within 180 days after the end of such 180 day period)

insurance proceeds are not required to be applied to repay Term Loans pursuant
to Section 4.4(g); (ii) Capital Expenditures constituting Permitted Acquisitions

such Borrower it will pay) to Agent at the Payment Office such additional amount
of cash, to be held as security by Agent, as is equal to the aggregate Stated

Subsidiaries and then outstanding, and (v) enforce, as Agent or Collateral
Agent, all of the Liens and security interests created pursuant to the Security

<PAGE>   132
shall become due and payable forthwith without the requirement
of any such acceleration or request, and without presentment, demand, protest or
other notice of any kind, all of which are expressly waived by Borrowers, any
provision of this Agreement or any other Loan Document to the contrary
notwithstanding, and other amounts payable by Borrowers hereunder shall also
become immediately due and payable all without notice of any kind.

         Anything in this Section 10.1 to the contrary notwithstanding, Agent
shall, at the request of the Required Lenders, rescind and annul any
acceleration of the Loans by written instrument filed with Borrowers; provided
that at the time such acceleration is so rescinded and annulled: (A) all past
due interest and principal, if any, on the Loans and all other sums payable
under this Agreement and the other Loan Documents shall have been duly paid, and
(B) no other Event of Default shall have occurred and be continuing which shall
not have been waived in accordance with the provision of Section 12.1 hereof.

         Section 10.2. Rights Not Exclusive. The rights provided for in this
Agreement and the other Loan Documents are cumulative and are not exclusive of
any other rights, powers, privileges or remedies provided by law or in equity,
or under any other instrument, document or agreement now existing or hereafter
arising.

                                   ARTICLE XI
                                    THE AGENT

         In this Article XI, the Lenders agree among themselves as follows:

         Section 11.1. Appointment. The Lenders hereby appoint BT as Agent (for
purposes of this Article XI, the term "Agent" shall include BT in its capacity
as Collateral Agent pursuant to the Security Documents) to act as herein
specified herein and in the other Loan Documents. Each Lender hereby irrevocably
authorizes and each holder of any Note by the acceptance of such Note shall be
deemed to irrevocably authorize Agent to take such action on its behalf under
the provisions hereof, the other Loan Documents (including, without limitation,
to give notices and take such actions on behalf of the Required Lenders as are
consented to in writing by the Required Lenders) and any other instruments,
documents and agreements referred to herein or therein and to exercise such
powers hereunder and thereunder as are specifically delegated to Agent by the
terms hereof and thereof and such other powers as are reasonably incidental
thereto. Agent may perform any of its duties hereunder and under the other Loan
Documents, by or through its officers, directors, agents, employees or
affiliates.

         Section 11.2. Nature of Duties. Agent shall have no duties or
responsibilities except those expressly set forth in this Agreement. The duties
of Agent shall be mechanical and administrative in nature. EACH LENDER HEREBY
ACKNOWLEDGES AND AGREES THAT AGENT SHALL NOT HAVE, BY REASON OF THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT, A FIDUCIARY RELATIONSHIP TO OR IN RESPECT OF ANY
LENDER. Nothing in any of the Loan Documents, expressed or implied, is intended
to or shall be so construed as to impose upon Agent any obligations in respect
of any of the Loan Documents except as expressly set forth herein or therein.
Each Lender shall make its own independent investigation of the financial
condition and affairs of Holdings and Borrowers in connection with the making
and the continuance of the Loans hereunder and shall make its own


                                      131

<PAGE>   133

appraisal of the credit worthiness of Holdings and Borrowers, and Agent shall
have no duty or responsibility, either initially or on a continuing basis, to
provide any Lender with any credit or other information with respect thereto,
whether coming into its possession before making of the Loans or at any time or
times thereafter. Agent will promptly notify each Lender at any time that the
Required Lenders have instructed it to act or refrain from acting pursuant to
Article X.

         Section 11.3. Exculpation, Rights Etc. Neither Agent nor any of its
officers, directors, agents, employees or affiliates shall be liable for any
action taken or omitted by them hereunder or under any of the other Loan
Documents, or in connection herewith or therewith, unless resulting primarily
from its or their gross negligence, willful misconduct or bad faith. Agent shall
not be responsible to any Lender for any recitals, statements, representations
or warranties herein or for the execution, effectiveness, genuineness, validity,
enforceability, collectibility, or sufficiency of any of the Loan Documents or
any other document or the financial condition of Holdings or Borrowers. Agent
shall not be required to make any inquiry concerning either the performance or
observance of any of the terms, provisions or conditions of this Agreement or
any of the Loan Documents or any other Document or the financial condition of
Holdings or Borrowers, or the existence or possible existence of any Unmatured
Event of Default or Event of Default unless requested to do so by the Required
Lenders. Agent may at any time request instructions from the Lenders with
respect to any actions or approvals (including the failure to act or approve)
which by the terms of any of the Loan Documents, Agent is permitted or required
to take or to grant, and if such instructions are requested, Agent shall be
absolutely entitled to refrain from taking any action or to withhold any
approval and shall not be under any liability whatsoever to any Person for
refraining from any action or withholding any approval under any of the Loan
Documents until it shall have received such instructions from the Required
Lenders. Without limiting the foregoing, no Lender shall have any right of
action whatsoever against Agent as a result of Agent acting, approving or
refraining from acting or approving under any of the Loan Documents in
accordance with the instructions of the Required Lenders or, to the extent
required by Section 12.1, all of the Lenders.

         Section 11.4. Reliance. Agent shall be entitled to rely, and shall be
fully protected in relying, upon any notice, writing, resolution, notice,
statement, certificate, order or other document or any telephone, telex,
teletype or telecopier message believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person, and, with respect to all
matters pertaining herein or to any of the other Loan Documents and its duties
hereunder or thereunder, upon advice of counsel selected by Agent.

         Section 11.5. Indemnification. To the extent Agent is not reimbursed
and indemnified by Borrowers, the Lenders will reimburse and indemnify Agent for
and against any and all liabilities, obligations, losses, damages, claims,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by, or asserted
against Agent in any way relating to or arising out of this Agreement or any of
the other Loan Documents or any action taken or omitted by Agent under this
Agreement or any of the other Loan Documents, in proportion to each Lender's
Aggregate Pro Rata Share of the outstanding Loans and Commitments hereunder;
provided, however, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, claims, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from Agent's gross
negligence or

                                      132

<PAGE>   134

willful misconduct. The obligations of the Lenders under this Section 11.5 shall
survive the payment in full of the Notes and the termination of this Agreement.

    For purposes hereof, "Aggregate Pro Rata Share" means, when used with
reference to any Lender and any described aggregate or total amount, an amount
equal to the result obtained by multiplying such desired aggregate or total
amount by a fraction the numerator of which shall be the aggregate principal
amount of such Lender's Revolving Loan, Term A Loan and Term B Loan and the
denominator of which shall be aggregate of all of the Loans outstanding
hereunder.

         Section 11.6. Agent In Its Individual Capacity. With respect to its
Loans and Commitments (and its Revolver Pro Rata Share, Term A Pro Rata Share,
Term B Pro Rata Share or Pro Rata Share, as applicable, thereof), Agent shall
have and may exercise the same rights and powers hereunder and is subject to the
same obligations and liabilities as and to the extent set forth herein for any
other Lender or holder of Obligations. The terms "Lenders", "holder of
Obligations" or "Required Lenders" or any similar terms shall, unless the
context clearly otherwise indicates, include Agent in its individual capacity as
a Lender, one of the Required Lenders or a holder of Obligations. Agent may
accept deposits from, lend money to, and generally engage in any kind of
banking, trust or other business with Holdings, any Borrower or any Subsidiary
or affiliate of Holdings as if it were not acting as Agent hereunder or under
any other Loan Document, including, without limitation, the acceptance of fees
or other consideration for services without having to account for the same to
any of the Lenders.

         Section 11.7. Notice of Default. Agent shall not be deemed to have
knowledge or notice of the occurrence of any Event of Default or Unmatured Event
of Default hereunder unless Agent has received written notice from a Lender or
Borrowers referring to this Agreement describing such Event of Default or
Unmatured Event of Default and stating that such notice is a "notice of
default". In the event that Agent receives such a notice, Agent shall give
prompt notice thereof to the Lenders.

         Section 11.8. Holders of Obligations. Agent may deem and treat the
payee of any Obligation as reflected on the books and records of Agent as the
owner thereof for all purposes hereof unless and until a written notice of the
assignment or transfer thereof shall have been filed with Agent pursuant to
Section 12.8(c). Any request, authority or consent of any Person who, at the
time of making such request or giving such authority or consent, is the holder
of any Obligation shall be conclusive and binding on any subsequent holder,

deemed to have any fiduciary relationship with any Lender. Each Lender
acknowledges that it has not relied, and will not rely, on any such institution
in deciding to enter into this Agreement or in taking or not taking any action

         Section 12.1. No Waiver; Modifications in Writing. (a) No failure or
delay on the part of Agent or any Lender in exercising any right, power or

the extensions of Term Loans and Revolving Commitments are included in such
determination on the date hereof) or (v) consent to the assignment or transfer
by Holdings or any Borrower of any of its rights and obligations under this
Agreement; provided, further, that no such amendment, modification, supplement,

lesser prepayment, repayment or commitment reduction, alter the required
application of any prepayments or repayments (or commitment reduction), as
between the various Facilities pursuant to clause (i) of the first sentence of
Section 4.5(a), clause (i) of the second sentence of Section 4.5(a) and the
fourth and fifth sentences of Section 4.5(a) (although the Required Lenders may
waive in whole or in part, any such prepayment, repayment or commitment
reduction so long as the application, as amongst the various Facilities, of any
such prepayment, repayment or commitment reduction which is still required to be
made is not altered), (6) without the consent of each Term A Lender, amend the
definition of Term A Pro Rata Share, without the consent of each Term B Lender,

<PAGE>   137

consent of the Super Majority Lenders of the Revolving Facility, amend the

         (b) If, in connection with any proposed change, waiver, discharge or
termination to any of the provisions of this Agreement as contemplated by
clauses (a)(i) through (v), inclusive, of the first proviso to the third
sentence of Section 12.1(a), the consent of the Required Lenders is obtained but
the consent of one or more of such other Lenders whose consent is required is
not obtained, then Borrowers shall have the right, so long as all non-consenting
Lenders whose individual consent is required are treated as described in either
clauses (A) or (B) below, to either (A) replace each such non-consenting Lender
or Lenders (or, at the option of Borrowers if the respective Lender's consent is
required with respect to less than all Loans, to replace only the respective
Loans of the respective non-consenting Lender which gave rise to the need to
obtain such Lender's individual consent) with one or more Replacement Lenders
pursuant to Section 3.7 so long as at the time of such replacement, each such
Replacement Lender consents to the proposed amendment, modification, supplement.
waiver, discharge, termination or other change or (B) terminate such
non-consenting Lender's Revolving Commitment and Term A Commitment and repay all
outstanding Loans of such Lender which gave rise to the need to obtain such
Lender's consent, in accordance with Section 4.l(b) and/or 4.3; provided that,
unless the Revolving Commitment and Term A Commitment terminated and Loans
repaid pursuant to the preceding clause (B) are immediately replaced in full at
such time through the addition of new Lenders or the increase of the Commitments
and/or outstanding Loans of existing Lenders (who in each case must specifically
consent thereto), then in the case of any action pursuant to preceding clause
(B) the Required Lenders (determined before giving effect to the proposed
action) shall specifically consent thereto, provided, further, that in any event
Borrowers shall not have the right to replace a Lender, terminate its Revolving
Commitment or Term A Commitment or repay its Loans solely as a result of the
exercise of such Lender's rights (and the withholding of any required consent by
such Lender) contemplated by the first proviso to this Section 12.1(b).

         Section 12.2. Further Assurances. Each Borrower agrees to do such
further acts and things and to execute and deliver to Agent such additional
assignments, agreements, powers and instruments, as Agent may reasonably require
or deem advisable to carry into effect the purposes of this Agreement or any of
the Loan Documents or to better assure and confirm unto Agent its rights, powers
and remedies hereunder.

         Section 12.3. Notices, Etc. Except where telephonic instructions or
notices are authorized herein to be given, all notices, demands, instructions
and other communications required or permitted to be given to or made upon any
party hereto or any other Person shall be in writing and shall be personally
delivered or sent by registered or certified mail, postage prepaid, return
receipt requested, or by a reputable overnight or courier delivery service, or
by prepaid telex or telecopier, and shall be deemed to be given for purposes of
this Agreement on the third day after deposit in registered or certified mail,
postage prepaid, and otherwise on the date that such writing is delivered or
sent to the intended recipient thereof, or in the case of notice delivered by
telecopy, upon completion of transmission with a copy of such notice also being
delivered under any of the methods provided above, all in accordance with the
provisions of this Section 12.3. Unless otherwise specified in a notice sent or
delivered in accordance with


                                      136

<PAGE>   138

the foregoing provisions of this Section 12.3, notices, demands, instructions
and other communications in writing shall be given to or made upon the
respective parties hereto at their respective addresses (or to their respective
telex, TWX or telecopier numbers) indicated on Schedule 12.3 or, in the case of
any Assignee, on its signature page to its Assignment and Assumption Agreement
and, in the case of telephonic instructions or notices, by calling the telephone
number or numbers indicated for such party on Schedule 12.3 hereto or such
Assignment Agreement, as the case may be.

         Section 12.4. Costs, Expenses and Taxes; Indemnification.

         (a) Generally. Borrowers agree to jointly and severally pay promptly
upon request by Agent (or any Lender, in connection with any enforcement as
provided below) all reasonable out-of-pocket costs and expenses in connection
with the negotiation, preparation, printing, typing, reproduction, execution and
delivery and syndication of this Agreement and the other Loan Documents and the
documents and instruments referred to herein and therein and any amendment,
waiver, consent relating hereto or thereto or other modifications of (or
supplements to) any of the foregoing and any and all other documents and
instruments furnished pursuant hereto or thereto or in connection herewith or
therewith, including without limitation, the reasonable fees and out-of-pocket
expenses of Winston & Strawn, special counsel to Agent, and any local counsel
retained by Agent relative thereto, other Attorney Costs, independent public
accountants and other outside experts retained by Agent and all search fees,
appraisal fees and expenses, title insurance policy fees, costs and expenses and
filing and recording fees, and all costs and expenses (including, without
limitation, Attorney Costs), if any, of Agent and each Lender in connection with
the enforcement of this Agreement, any of the Loan Documents or any other
agreement furnished pursuant hereto or thereto or in connection herewith or
therewith. In addition, Borrowers agree to jointly and severally pay any and all
present and future stamp, transfer, excise and other similar taxes payable or
determined to be payable in connection with the execution and delivery of this
Agreement, any Loan Document, or the making of any Loan (but excluding any tax
determined by reference to the net income or profits of Agent or any Lender
imposed by the jurisdiction in which Agent's or such Lender's principal office
or applicable lending office is located), and each agrees to save and hold Agent
and each Lender harmless from and against any and all liabilities with respect
to or resulting from any delay by any Borrower in paying, or omission by any
Borrower to pay, such taxes. Any portion of the foregoing fees, costs and
expenses which remains unpaid more than thirty (30) days following Agent's or
any Lender's statement and request for payment thereof shall bear interest from
the date of such statement and request to the date of payment at the Default
Rate.

         (b) Indemnification. Borrowers agree to jointly and severally indemnify
and hold harmless Agent and each Lender and each director, officer, trustee,
employee and Affiliate of Agent and each Lender (each such Person an
"Indemnified Person" and collectively, the "Indemnified Persons") from and
against all losses, claims, damages, obligations (including removal or remedial
actions), expenses or liabilities (not including Taxes as to which Borrowers are
not required to make any payment of additional amounts pursuant to Section 4.7
hereof) to which such Indemnified Person may become subject, insofar as such
losses, claims, damages, penalties, obligations (including removal or remedial
actions), expenses or liabilities (or actions, suits or proceedings including
any inquiry or investigation or claims in respect thereof (whether or not Agent
or any Lender is a party thereto)) arise out of, in any way relate to, or result
from

                                      137

<PAGE>   139

the transactions contemplated by this Agreement or any of the other Loan
Documents and to reimburse each Indemnified Person upon their demand, for any
Attorney Costs or other expenses incurred in connection with investigating,
preparing to defend or defending any such loss, claim, damage, liability, action
or expense; provided, however, (a) that no Indemnified Person shall have the
right to be so indemnified hereunder for any loss, claim, damage, penalties,
obligations, expense or liability to the extent it arises or results primarily
from the gross negligence or willful misconduct or bad faith of such Indemnified
Person and (b) that nothing contained herein shall affect the express
contractual obligations of the Lenders to Borrowers contained herein. If any
action, suit or proceeding arising from any of the foregoing is brought against
Agent, any Lender or any other Person indemnified or intended to be indemnified
pursuant to this Section 12.4, Borrowers will, if requested by Agent, any Lender
or any such Indemnified Person, resist and defend such action, suit or
proceeding or cause the same to be resisted and defended by counsel reasonably
satisfactory to the Person or Persons indemnified or intended to be indemnified.
Each Indemnified Person shall, unless Agent, a Lender or other Indemnified
Person has made the request described in the preceding sentence and such request
has been complied with, have the right to employ its own counsel (or (but not as
well as) staff counsel) to investigate and control the defense of any matter
covered by such indemnity and the reasonable fees and expenses of such counsel
shall be at the expense of the indemnifying party. Borrowers further agree to
jointly and severally indemnify and hold each Indemnified Person harmless from
all loss, cost (including Attorney Costs), liability and damage whatsoever
incurred by such Indemnified Person, excluding any liability arising out of the
gross negligence, willful misconduct or bad faith of such Indemnified Person, by
reason of any violation of any Environmental Laws or Environmental Permits or
for the Release or threatened Release of any Hazardous Materials into the
environment for which Holdings, any Borrower or any of its Subsidiaries has any
liability or which occurs upon the Mortgaged Property or which is related to any
property currently or formerly owned, leased or operated by or on behalf of
Holdings, any Borrower or any of its Subsidiaries, or by reason of the
imposition of any Environmental Lien or which occurs by a breach of any of the
representations, warranties or covenants relating to environmental matters
contained herein, including, without limitation, by reason by any matters
disclosed in Schedule 6.19, provided that, with respect to any liabilities
arising from acts or failure to act for which Borrower or any of its
Subsidiaries is strictly liable under any Environmental Law or Environmental
Permit, Borrowers' obligation to each Indemnified Person under this indemnity
shall likewise be without regard to fault on the part of any Borrower or any
such Subsidiary. If any Borrower shall fail to do any act or thing which it has
covenanted to do hereunder or any representation or warranty on the part of any
Borrower or any Subsidiary contained herein or in any other Loan Document shall
be breached, Agent may (but shall not be obligated to) do the same or cause it
to be done or remedy any such breach, and may expend its funds for such purpose,
and will use reasonable efforts to give prompt written notice to Borrowers that
it proposes to take such action. Any and all amounts so expended by Agent shall
be repaid to it by Borrowers promptly upon Agent's demand therefor, with
interest at the Default Rate in effect from time to time during the period
including the date so expended by Agent to the date of repayment. To the extent
that the undertaking to indemnify, pay or hold harmless Agent or any Lender as
set forth in this Section 12.4 may be unenforceable because it is violative of
any law or public policy, Borrowers shall make the maximum contribution to the
payment and satisfaction of each of the indemnified liabilities which is
permissible under applicable law. The obligations

                                      138

<PAGE>   140

of Borrowers under this Section 12.4 shall survive the termination of this
Agreement and the discharge of Borrowers' other Obligations hereunder.

         (c) Foreign Exchange Indemnity. If any sum due from any Borrower under
this Agreement or any order or judgment given or made in relation hereto has to
be converted from the currency (the "first currency") in which the same is
payable hereunder or under such order or judgment into another currency (the
"second currency") for the purpose of (i) making or filing a claim or proof
against any Borrower with any Governmental Authority or in any court or
tribunal, or (ii) enforcing any order or judgment given or made in relation
hereto, Borrowers agree to jointly and severally indemnify and hold harmless
each of the Persons to whom such sum is due from and against any loss actually
suffered as a result of any discrepancy between (a) the rate of exchange used to
convert the amount in question from the first currency into the second currency,
and (b) the rate or rates of exchange at which such Person, acting in good faith
in a commercially reasonable manner, purchased the first currency with the
second currency after receipt of a sum paid to it in the second currency in
satisfaction, in whole or in part, of any such order, judgment, claim or proof.
The foregoing indemnity shall constitute a separate obligation of Borrowers
distinct from its other obligations hereunder and shall survive the giving or
making of any judgment or order in relation to all or any of such other
obligations.

         Section 12.5. Confirmations. Borrowers and each holder of any portion
of the Obligations agree from time to time, upon written request received by it
from the other, to confirm to the other in writing (with a copy of each such
confirmation to Agent) the aggregate unpaid principal amount of the Loan or
Loans and other Obligations then outstanding.

         Section 12.6. Adjustment; Setoff.

         (a) If any Lender (a "Benefited Lender") shall at any time receive any
payment of all or part of its Loans, or interest thereon, or receive any
collateral in respect thereof (whether voluntarily or involuntarily, by setoff,
pursuant to events or proceedings of the nature referred to in Section 10.1(e)
or Section 10.1(f) hereof, or otherwise) in a greater proportion than any such
payment to and collateral received by any other Lender in respect of such other
Lender's Loans or interest thereon, such Benefited Lender shall purchase for
cash from the other Lenders such portion of each such other Lender's Loans, or
shall provide such other Lenders with the benefits of any such collateral, or
the proceeds thereof, as shall be necessary to cause such Benefited Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each Lender; provided, however, that if all or any portion of such excess
payment or benefits is thereafter recovered from such Benefited Lender, such
purchase shall be rescinded, and the purchase price and benefits returned, to
the extent of such recovery, but without interest. Borrowers agree that each
Lender so purchasing a portion of another Lender's Loans may exercise all rights
of payment (including, without limitation, rights of setoff) with respect to
such portion as fully as if such Lender were the direct holder of such portion.

         (b) In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to Borrowers, any
such notice being expressly waived by Borrowers, upon the occurrence and during
the continuance of an Event of Default, to set off and apply against any
Obligations, whether matured or unmatured, of Borrowers to such Lender, any
amount owing from such Lender to Borrowers, at or at any time

                                      139

<PAGE>   141

after, the happening of any of the above-mentioned events, and the aforesaid
right of setoff may be exercised by such Lender against Borrowers or against any
trustee in bankruptcy, debtor in possession, assignee for the benefit of
creditors, receivers, or execution, judgment or attachment creditor of
Borrowers, or against anyone else claiming through or against, Borrowers or such
trustee in bankruptcy, debtor in possession, assignee for the benefit of
creditors, receivers, or execution, judgment or attachment creditor,
notwithstanding the fact that such right of setoff shall not have been exercised
by such Lender prior to the making, filing or issuance, or service upon such
Lender of, or of notice of, any such petition, assignment for the benefit of
creditors, appointment or application for the appointment of a receiver, or
issuance of execution, subpoena, order or warrant. Each Lender agrees promptly
to notify in writing Borrowers and Agent after any such setoff and application
made by such Lender, provided that the failure to give such notice shall not
affect the validity of such setoff and application.

         (c) Borrowers expressly agree that to the extent any Borrower makes a
payment or payments and such payment or payments, or any part thereof, are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or are required to be repaid to a trustee, receiver, or any other party under
any bankruptcy act, state or federal law, common law or equitable cause, then to
the extent of such payment or repayment, the Indebtedness to the Lenders or part
thereof intended to be satisfied shall be revived and continued in full force
and effect as if said payment or payments had not been made.

         Section 12.7. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto on separate
counterparts, each of which counterparts, when so executed and delivered, shall
be deemed to be an original and all of which counterparts, taken together, shall
constitute but one and the same Agreement.

         Section 12.8. Binding Effect; Assignment; Addition and Substitution of
Lenders.

         (a) This Agreement shall be binding upon, and inure to the benefit of,
Holdings, Borrowers, Agent, the Lenders, all future holders of the Notes and
their respective successors and assigns; provided, however, that neither
Holdings nor any Borrower may assign its rights or obligations hereunder or in
connection herewith or any interest herein (voluntarily, by operation of law or
otherwise) without the prior written consent of Agent and all of the Lenders.

         (b) Each Lender may at any time sell to one or more banks or other
entities ("Participants") participating interests in all or any portion of its
rights and obligations under the Loan Documents (including all or any portion of
its Commitment and Loans and related outstanding Obligations) (in respect of any
Lender, its "Credit Exposure"). In the event of any such sale by a Lender of
participating interests to a Participant, such Lender's obligations under this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, and Borrowers and Agent shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Each Borrower agrees that if amounts
outstanding under this Agreement or any of the Loan Documents are due or unpaid,
or shall have been declared or shall have become due and payable upon the
occurrence of an Event of Default, each Participant shall be deemed to have the
right of setoff in respect of its participating interest in amounts owing under
this Agreement and the Loan


                                      140

<PAGE>   142

Documents to the same extent as if the amount of its participating interest were
owing directly to it as a Lender under this Agreement or any other Loan
Document, provided, however, that such right of setoff shall be subject to the
obligation of such Participant to share with the Lenders, and the Lenders agree
to share with such Participant, as provided in Section 12.6. Each Borrower also
agrees that each Participant shall be entitled to the benefits of Section 3.6
and 4.7 with respect to its participation in the Loans outstanding from time to
time, provided that such Participant's benefits under Sections 3.6 and 4.7 shall
be limited to the benefits that the primary Lender would be entitled to
thereunder. Each Lender agrees that any agreement between such Lender and any
such Participant in respect of such participating interest shall not restrict
such Lender's right to approve or agree to any amendment, restatement,
supplement or other modification to, waiver of, or consent under, this Agreement
or any of the Loan Documents except to the extent that any of the forgoing would
(i) extend the final scheduled maturity of any Loan or Note in which such
participant is participating (it being understood that amending the definitions
of Scheduled Term A Repayments (other than the Term A Loan Maturity Date),
Scheduled Term B Repayments (other than the Term B Loan Maturity Date) or
Scheduled Acquisition Repayments (other than the Acquisition Loan Maturity Date)
or amending the other mandatory prepayment provisions or financial covenants
shall not constitute an extension of the final scheduled maturity of any Loan or
Note) or extend the stated maturity of any Letter of Credit in which such
participant is participating beyond the Revolver Termination Date or beyond the
Rollover LC Termination Date in the case of any Rollover Letter of Credit, or
reduce the rate or extend the time of payment of interest or fees on any such
Loan, Note or Letter of Credit (except in connection with a waiver of
applicability of any post-default increase in interest rates) or reduce the
principal amount thereof, or increase the amount of the participant's
participation over the amount thereof then in effect (it being understood that
waivers or modifications of conditions precedent, covenants, Events of Default
or Unmatured Events of Default or of a mandatory reduction in Commitments shall
not constitute a change in the terms of such participation, and that an increase
in any Commitment or Loan shall be permitted without the consent of any
participant if the participant's participation is not increased as a result
thereof), (ii) consent to the assignment or transfer by any Borrower of any of
its rights and obligations under this Agreement or (iii) release all or
substantially all of the Collateral under all of the Security Documents (except
as expressly provided in the Loan Documents) supporting the Loans and/or Letters
of Credit hereunder in which such participant is participating.

         (c) Any Lender may at any time assign to one or more Eligible Assignees
(treating for all purposes under Section 12.8(c) any fund that invests in bank
loans and any other fund that invests in bank loans and is managed by the same
investment advisor of such fund or by an Affiliate of such investment advisor as
a single Eligible Assignee), including an Affiliate thereof (each an
"Assignee"), all or any part of its Credit Exposure pursuant to an Assignment
and Assumption Agreement, provided that (i) it assigns its Credit Exposure in an
amount not less than $5,000,000 (or if less the entire amount of Lender's Credit
Exposure) and (ii) any assignment of all or any portion of any Lender's Credit
Exposure to an Assignee other than another Lender shall require the prior
written consent of Agent and, provided no Unmatured Event of Default or Event of
Default then exists and is continuing, Borrowers (the consent of Borrowers or
Agent not to be unreasonably withheld or delayed), and provided further, that
notwithstanding the foregoing limitations in clauses (i) and (ii), any Lender
may at any time assign all or any part of its Credit Exposure to (x) any
Affiliate of such Lender, (y) in the case of any Lender that is a fund that
invests in bank loans, any other fund that invests in bank loans and

                                      141

<PAGE>   143

is managed by the same investment advisor of such Lender or by an Affiliate of
such investment advisor or (z) any other Lender; and provided, further, that
notwithstanding the foregoing, the sale or assignment by any Eligible Assignee
(which acquired an interest in the Credit Exposure of a Lender in an amount less
than $5,000,000 pursuant to the immediately preceding proviso) to any Person
which is not a Lender or an Affiliate of such Eligible Assignee or, in the case
of any Eligible Assignee that is a fund that invests in bank loans, any other
fund that invests in bank loans and is managed by the same investment advisor of
such Eligible Assignee or by an Affiliate of such investment advisor, shall, if
all the Affiliates of such Lender (and, in the case of any Lender that is a fund
that invests in bank loans, all other funds that invest in bank loans and are
managed by the same investment advisor of such Lender or by an Affiliate of such
investment advisor) have a Credit Exposure in the aggregate of $5,000,000 or
more, be subject to the minimum assignment requirement of $5,000,000. Upon
execution of an Assignment and Assumption Agreement and the payment of a
nonrefundable assignment fee of $3,500 in immediately available funds to Agent
at its Payment Office in connection with each such assignment, written notice
thereof by such transferor Lender to Agent and the recording by Agent of such
assignment and the resulting effect upon the Loans, the Revolving Commitment and
Term A Commitment of the assigning Lender and the Assignee, the Assignee shall
have, to the extent of such assignment, the same rights and benefits as it would
have if it were a Lender hereunder and the holder of the Obligations (provided
that Borrowers and Agent shall be entitled to continue to deal solely and
directly with the assignor Lender in connection with the interests so assigned
to the Assignee until written notice of such assignment, together with payment
instructions, addresses and related information with respect to the Assignee,
shall have been given to Borrowers and Agent by the assignor Lender and the
Assignee) and, if the Assignee has expressly assumed, for the benefit of
Borrowers, some or all of the transferor Lender's obligations hereunder, such
transferor Lender shall be relieved of its obligations hereunder to the extent
of such assignment and assumption, and except as described above, no further
consent or action by Borrowers, the Lenders or Agent shall be required. At the
time of each assignment pursuant to this Section 12.8(c) to a Person which is
not already a Lender hereunder and which is not a United States person (as such
term is defined in Section 7701(a)(30) of the Code) United States Federal income
tax purposes, the respective Assignee shall provide to Borrowers and Agent the
appropriate IRS Forms (and, if applicable a Section 4.7(d)(ii) Certificate)
described in Section 4.7(d). Each Assignee shall take such Credit Exposure
subject to the provisions of this Agreement and to any request made, waiver or
consent given or other action taken hereunder, prior to the receipt by Agent and
Borrowers of written notice of such transfer, by each previous holder of such
Credit Exposure. Such Assignment and Assumption Agreement shall be deemed to
amend this Agreement and Schedule 1.1(a) hereto, to the extent, and only to the
extent, necessary to reflect the addition of such Assignee as a Lender and the
resulting adjustment of all or a portion of the rights and obligations of such
transferor Lender under this Agreement, the Maximum Commitment, the
determination of its Pro Rata Share, Term A Pro Rata Share, Term B Pro Rata
Share or Revolver Pro Rata Share, as applicable (rounded to twelve decimal
places), the Loans, any outstanding Letters of Credit and any new Notes to be
issued, at Borrowers' expense, to such Assignee, and no further consent or
action by Borrowers or the Lenders shall be required to effect such amendments.

         (d) Each Borrower authorizes each Lender to disclose to any Participant
or Assignee (each, a "Transferee") and any prospective Transferee any and all
financial information in such Lender's possession concerning Holdings or any of
its Subsidiaries which has been

                                      142

<PAGE>   144

delivered to such Lender by or on behalf of Holdings or any Borrower pursuant to
this Agreement or which has been delivered to such Lender by Holdings or any of
its Subsidiaries in connection with such Lender's credit evaluation of Borrowers
prior to entering into this Agreement; provided that such Transferee or
prospective Transferee agrees to treat any such information as confidential in
accordance with Section 12.15.

         (e) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time pledge or assign all or any portion of its rights
under this Agreement and the other Loan Documents (including, without
limitation, the Notes held by it) to any Federal Reserve Bank in accordance with
Regulation A of the Federal Reserve Board without notice to, or the consent of,
Agent or Borrowers, and any Lender that is a fund that invests in bank loans
may, without notice to, or the consent of, Agent or Borrowers, pledge all or any
portion of its rights under this Agreement and the other Loan Documents
(including, without limitation, the Notes held by it) to any trustee for, or any
other representative of, holders of obligations owed, or securities issued, by
such fund, as security for such obligations or securities; provided that any
foreclosure or similar action by such trustee shall be subject to the provisions
of this Section concerning assignments. No such pledge or assignment shall
release the transferor Lender from its obligations hereunder.

         Section 12.9. CONSENT TO JURISDICTION; MUTUAL WAIVER OR JURY TRIAL.

              (A) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT

    PARTY AGREES TO DESIGNATE A NEW DESIGNEE, APPOINTEE AND AGENT IN NEW YORK
    CITY ON THE TERMS AND FOR THE PURPOSES OF THIS PROVISION SATISFACTORY TO

    PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL
    PROCEEDINGS OR OTHERWISE PROCEED AGAINST EACH CREDIT PARTY IN ANY OTHER
    JURISDICTION.

              (B) EACH CREDIT PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION
    WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY OF THE
    AFORESAID ACTIONS OR PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS
    AGREEMENT OR ANY OTHER LOAN DOCUMENT BROUGHT IN THE COURTS REFERRED TO IN
    CLAUSE (A) ABOVE AND HEREBY FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO
    PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH ACTION OR PROCEEDING BROUGHT
    IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

              (C) EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY
    WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY COURT OR JURISDICTION,
    INCLUDING WITHOUT LIMITATION THOSE REFERRED TO IN CLAUSE (A) ABOVE, IN
    RESPECT TO ANY MATTER ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE
    OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

         Section 12.10. GOVERNING LAW. THIS AGREEMENT AND EACH NOTE SHALL BE
DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK, AND FOR
ALL PURPOSES SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS AND DECISIONS OF
SAID STATE, INCLUDING SECTIONS 5-1401 and 5-1402 OF THE NEW YORK GENERAL
OBLIGATIONS LAW BUT EXCLUDING ALL OTHER CHOICE OF LAW AND CONFLICTS OF LAWS
RULES.

         Section 12.11. Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

         Section 12.12. Registry. Each Borrower hereby designates Agent to serve
as such Borrower's agent, solely for purposes of this Section 12.12 to maintain
a register (the "Register") on which it will record the Commitment from time to
time of each of the Lenders, the Loans made by each of the Lenders and each
repayment in respect of the principal amount of the Loans of each Lender.
Failure to make any such recordation, or any error in such recordation shall not
affect any Borrower's obligations in respect of such Loans. With respect to any
Lender, the transfer of the Commitments of such Lender and the rights to the
principal of, and interest on, any Loan made pursuant to such Commitment shall
not be effective until such transfer is


                                      144

<PAGE>   146

recorded on the Register maintained by Agent with respect to ownership of such
Commitment and Loans and prior to such recordation all amounts owing to the
transferor with respect to such Commitments and Loans shall remain owing to the
transferor. The registration of assignment or transfer of all or part of any
Commitment and Loans shall be recorded by Agent on the Register only upon the
acceptance by Agent of a properly executed and delivered Assignment and
Assumption Agreement pursuant to Section 12.8(c). Coincident with the delivery
of such an Assignment and Assumption Agreement to Agent for acceptance and
registration of assignment or transfer of all or part of a Loan, or as soon
thereafter as practicable, the assigning or transferor Lender shall surrender
the Note evidencing such Loan, and thereupon one or more new Notes in the same
aggregate principal amount then owing to such assignor or transferor Lender
shall be issued to the assigning or transferor Lender and/or the new Lender.
Borrowers agree to jointly and severally indemnify Agent from and against any
and all losses, claims, damages and liabilities of whatsoever nature which may
be imposed on, asserted against or incurred by Agent in performing its duties
under this Section 12.12, except as resulting primarily from the gross
negligence, bad faith or willful misconduct of Agent.

         Section 12.13. Headings. The Table of Contents and Article and Section
headings used in this Agreement are for convenience of reference only and shall
not affect the construction of this Agreement.

         Section 12.14. Termination of Agreement. This Agreement shall terminate
when the Commitment of each Lender has terminated and all outstanding
Obligations (other than any unasserted contingent or indemnification
obligations) and Loans have been paid in full and all Letters of Credit have
expired or been terminated; provided, however, that the rights and remedies of
Agent and each Lender with respect to any representation and warranty made by
any Credit Party pursuant to this Agreement or any other Loan Document, and the
indemnification provisions contained in this Agreement and any other Loan
Document, shall be continuing and shall survive any termination of this
Agreement or any other Loan Document. Upon such termination, all Liens created
under the Loan Documents shall automatically terminate and Agent agrees to
execute such lien release documentation as Borrowers may reasonably request at
Borrowers' sole cost and expense.

         Section 12.15. Confidentiality. Each of the Lenders severally agrees to
keep confidential all non-public information pertaining to Holdings, Borrowers
and their Subsidiaries which is provided to it by any such parties in accordance
with such Lender's customary procedures for handling confidential information of
this nature and in a prudent fashion, and shall not disclose such information to
any Person except (i) to the extent such information is public when received by
such Lender or becomes public thereafter due to the act or omission of any party
other than a Lender, (ii) to the extent such information is independently
obtained from a source other than Holdings, Borrowers or their Subsidiaries and
such information from such source is not, to such Lender's knowledge, subject to
an obligation of confidentiality or, if such information is subject to an
obligation of confidentiality, that disclosure of such information is permitted,
(iii) to an Affiliate of such Lender (who will in turn be required to maintain
confidentiality as if it were a Lender party to this Agreement), counsel,
auditors, examiners of any regulatory authority having jurisdiction over such
Lender, accountants and other consultants retained by Agent or any Lender, (iv)
in connection with any litigation regarding this Agreement or any Loan Document
or the enforcement of the rights of any Lender or Agent under this

                                      145

<PAGE>   147

Agreement or any other Loan Document, (v) to the extent required by any
applicable statute, rule or regulation or court order (including , without
limitation, by way of subpoena) or pursuant to the request of any Governmental
Authority having jurisdiction over any Lender or Agent; provided, however, that
in such event, if the Lender(s) are able to do so, the Lender shall provide
Borrowers with prompt notice of such requested disclosure so that Borrowers may
seek a protective order or other appropriate remedy, and, in any event, the
Lenders will endeavor in good faith to provide only that portion of such
information which, in the reasonable judgment of the Lender(s), is relevant and
legally required to be provided, or (vi) to the extent disclosure to other
entities is appropriate in connection with any proposed or actual assignment or
grant of a participation by any of the Lenders of interests in this Agreement
and/or any of the other Loan Documents to such other financial institutions (who
will in turn be required to maintain confidentiality as if they were Lenders
parties to this Agreement). In no event shall Agent or any Lender be obligated
or required to return any such information or other materials furnished by
Holdings or any Borrower.

         Section 12.16. Concerning the Collateral and the Loan Documents.

         (a) Authority. Each Lender (on its own behalf and on behalf of any
Affiliate of such Lender which is a Secured Creditor) authorizes and directs BT
to act as collateral agent and to enter into the Loan Documents relating to the
Collateral for the benefit of the Lenders and the other Secured Creditors. Each
Lender (on its own behalf and on behalf of any Affiliate of such Lender which is
a Secured Creditor) agrees that any action taken by the Agent, the Collateral
Agent or the Required Lenders (or, where required by the express terms, hereof,
a different proportion of the Lenders) in accordance with the provisions hereof
or of the other Loan Documents, and the exercise by the Agent, the Collateral
Agent or the Required Lenders (or, where so required, such different proportion)
of the powers set forth herein or therein, together with such other powers as
are reasonably incidental thereto, shall be authorized and binding upon all of
the Lenders and the other Secured Creditors. Without limiting the generality of
the foregoing, the Agent and the Collateral Agent shall have the sole and
exclusive right and authority to (i) act as the disbursing and collecting agent
for the Lenders and the other Secured Creditors with respect to all payments and
collections arising in connection herewith and with the Loan Documents relating
to the Collateral; (ii) execute and deliver each Loan Document relating to the
Collateral and accept delivery of each such agreement delivered by any Credit
Party, (iii) act as collateral agent for the Lenders and the other Secured
Creditors for purposes stated therein to the extent such perfection is required
under the Loan Documents, provided, however, the Agent and the Collateral Agent
hereby appoints, authorizes and directs each Lender and the other Secured
Creditors to act as collateral sub-agent for the Agent, the Collateral Agent and
the Lenders for purposes of the perfection of all security interests and Liens
with respect to each Credit Party's respective deposit accounts maintained with,
and cash and Cash Equivalents held by, such Lender or such other Secured
Creditor; (iv) manage, supervise and otherwise deal with the Collateral; (v)
take such action as is necessary or desirable to maintain the perfection and
priority of the security interests and liens created or purported to be created
by the Loan Documents, and (vi) except as may be otherwise specifically
restricted by the terms hereof or of any other Loan Document, exercise all
remedies given to the Agent or the Lenders with respect to the Collateral under
the Loan Documents relating thereto, applicable law or otherwise.

               (b) Release of Collateral.

               (i) The Agent and each Lender (on its own behalf and on behalf
         of any Affiliate of such Lender that is a Secured Creditor) hereby
         directs the Agent and the Collateral Agent to release, in accordance
         with the terms hereof, any Lien held by the Agent or the Collateral
         Agent, under the Security Documents:

                    (A) against all of the Collateral, upon final and
               indefeasible payment in full in cash of the Loans and Obligations
               (other than unasserted contingent and indemnification obligations
               which expressly survive termination) and termination of all
               Commitments and termination hereof;

                    (B) against any part of the Collateral sold or disposed of
               by Holdings or any of its Subsidiaries to the extent such sale or
               disposition is permitted hereby (or permitted pursuant to a
               waiver or consent of a transaction otherwise prohibited hereby);

                    (C) against any Collateral acquired by any Borrower or any
               of its Subsidiaries after the Closing Date and at least 80% of
               the purchase price therefor is within 120 days of the acquisition
               thereof financed with Purchase Money Indebtedness secured by a
               Lien permitted by clause (ix) of the definition of Customary
               Permitted Liens.

                    (D) so long as no Unmatured Event of Default or Event of
               Default has occurred and is continuing, in the sole discretion of
               the Agent upon the request of any Borrower, against any part of
               the Collateral with a fair market value of less than $1,000,000
               in the aggregate during the term of this Agreement as such fair
               market value may be certified to the Agent by such Borrower in an
               officer's certificate reasonably acceptable in form and substance
               to the Agent; and

                    (E) against a part of the Collateral which release does not
               require the consent of all of the Lenders as set forth in Section
               12.1(a)(ii), if such release is consented to by the Required
               Lenders;

provided, however, that (y) the Agent and the Collateral Agent shall not be
required to execute any such document on terms which, in its opinion, would
expose it to liability or create any obligation or entail any consequence other
than the release of such Liens without recourse or warranty, and (z) such
release shall not in any manner discharge, affect or impair the Obligations or
any Liens upon (or obligations of any Borrower or any of its Subsidiaries in
respect of) all interests retained by Borrowers and/or any of their
Subsidiaries, including (without limitation) the proceeds of any sale, all of
which shall continue to constitute part of the Collateral.

               (ii) Each Lender (on its own behalf and on behalf of any
         Affiliate of such Lender that is a Secured Creditor) hereby directs the
         Agent and the Collateral Agent (and the Agent and the Collateral Agent
         agree) to execute and deliver or file such termination and partial
         release statements and such other things as are necessary to release
         Liens to be released pursuant to this Section 12.16 promptly upon the
         effectiveness of any such release or enter into intercreditor
         agreements contemplated or permitted herein.

                                      147

<PAGE>   149

         (c) No Obligation. Neither the Agent nor the Collateral Agent shall
have any obligation whatsoever to any Lender or any other Secured Creditor or to
any other Person to assure that the Collateral exists or is owned by any Credit
Party or is cared for, protected or insured or has been encumbered or that the
Liens granted to the Agent and the Collateral Agent herein or pursuant to the
Loan Documents have been properly or sufficiently or lawfully created,
perfected, protected or enforced or are entitled to any particular priority, or
to exercise at all or in any particular manner or under any duty of care,
disclosure or fidelity, or to continue exercising, any of the rights,
authorities and powers granted or available to the Agent or the Collateral Agent
in any of the Loan Documents, it being understood and agreed that in respect of
the Collateral, or any act, omission or event related thereto, Agent and the
Collateral Agent may act in any manner it may deem appropriate, in its sole
discretion, given the Agent's and the Collateral Agent's own interests in the
Collateral as one of the Lenders and that the Agent and the Collateral Agent
shall not have any duty or liability whatsoever to any Lender, provided, that,
notwithstanding the foregoing, the Agent and the Collateral Agent shall be
responsible for its grossly negligent actions or actions constituting
intentional misconduct.

         Section 12.17. Effectiveness. This Agreement shall become effective on
the date (the "Effective Date") on which Holdings, Borrowers, Agent and each of
the Lenders shall have signed a counterpart of this Agreement (whether the same
or different counterparts) and shall have delivered the same to the Agent at the
Notice Office (or to Agent's counsel as directed by such counsel) or, in the
case of the Lenders, shall have given to Agent or telephonic (confirmed in
writing), written, telex or facsimile notice (actually received) at such office
or the office of Agent's counsel that the same has been signed and mailed to it.
Agent will give Borrowers and each Lender prompt written notice of the
occurrence of the Effective Date.

                                  ARTICLE XIII
                        NATURE OF BORROWERS' OBLIGATIONS

         Section 13.1. Nature of Obligations. Notwithstanding anything to the
contrary contained elsewhere in this Agreement, it is understood and agreed by
the various parties to this Agreement that all obligations to repay principal
of, interest on, and all other amounts with respect to, all Term Loans,
Revolving Loans, Acquisition Loans, Swingline Loans, Rollover LC Obligations and
LC Obligations and all other Obligations pursuant to this Agreement and under
any Note (including, without limitation, all fees, indemnities and taxes in
connection therewith or in connection with the related Revolving Loan
Commitments, Term Loan Commitments or Acquisition Loan Commitments (if any))
shall constitute the joint and several obligations of NATG and LISN. In addition
to the direct obligations of the respective Borrowers with respect to
Obligations as described above, all such Obligations shall be guaranteed
pursuant to, and in accordance with the terms of, the Guaranty.

         Section 13.2. Independent Obligation. The obligations of each Borrower
with respect to the Obligations are independent of the obligations of the other
Borrower or any other guarantor, and a separate action or actions may be brought
and prosecuted against each Borrower, whether or not the other Borrower or any
other guarantor is joined in any such action or actions. Each Borrower waives,
to the fullest extent permitted by law, the benefit of any statute of
limitations affecting its liability hereunder or the enforcement thereof. Any
payment by either Borrower or other circumstance which operates to toll any
statute of limitations as to

                                      148

<PAGE>   150

such Borrower shall, to the fullest extent permitted by law, operate to toll the
statute of limitations as to each Borrower.

         Section 13.3. Authorization. Each Borrower authorizes Agent and the
Lenders without notice or demand (except as shall be required by applicable
statute and cannot be waived), and without affecting or impairing its liability
hereunder, from time to time to:

         (a) exercise or refrain from exercising any rights against the other
      Borrower or any guarantor or others or otherwise act or refrain from
      acting;

         (b) release or substitute the other Borrower, endorsers, guarantors or
      other obligors;

         (a) settle or compromise any of the Obligations of the other Borrower
      or any other Credit Party, any security therefor or any liability
      (including any of those hereunder) incurred directly or indirectly in
      respect thereof or hereof, and may subordinate the payment of all or any
      part thereof to the payment of any liability (whether due or not) of
      either Borrower to its creditors other than the Lenders;

         (b) apply any sums paid by the other Borrower or any other Person,
      howsoever realized to any liability or liabilities of such Borrower or
      other Person regardless of what liability or liabilities of such Borrower
      or other Person remain unpaid; and/or

         (c) consent to or waive any breach of, or act, omission or default
      under, this Agreement or any of the instruments or agreements referred to
      herein, or otherwise, by the other Borrower or any other Person.

         Section 13.4. Reliance. It is not necessary for Agent or any other
Lender to inquire into the capacity or powers of either Borrower or any of its
Subsidiaries or the officers, directors, members, partners or agents acting or
purporting to act on its behalf, and any Obligations made or created in reliance
upon the professed exercise of such powers shall constitute the joint and
several obligations of the Borrowers hereunder.

         Section 13.5. Contribution; Subrogation. Neither Borrower shall have
any rights of contribution or subrogation with respect to the other Borrower as
a result of payments made by it hereunder, in each case unless and until all
Obligations have been repaid in full in cash.

                            [signature pages follow]

                            INVESTOR RIGHTS AGREEMENT


                  THIS INVESTOR RIGHTS AGREEMENT (this "Agreement") is entered
into as of November 8, 1999, and the terms set forth in this Agreement shall
become effective upon the Effective Time (as defined in the Reorganization
Agreement (defined below)) by and among (i) Orius Corp., a Florida corporation

time to time on the attached "Schedule of New Stockholders" who at any time,
acquires securities of the Company and, as a condition thereto, executes a
counterpart of this Agreement or otherwise agrees to be bound by this Agreement
(such Persons being referred to collectively as the "New Stockholders"), and
(vii) LISN Holdings, Inc., an Ohio corporation ("LISN"). WS and each of the
Coinvestors are referred to herein collectively as the "Investors" and
individually as an "Investor". The Existing Orius Stockholders, the Former LISN
Shareholders, the Investors, the Coinvestors and the New Stockholders are
referred to herein collectively as the "Stockholders" and individually as a
"Stockholder". Capitalized terms used herein are defined in Section 15 hereof.

                  The Company, LISN, the Existing Orius Stockholders (in each
case by execution of a joinder agreement), the Former LISN Shareholders (in each
case by execution of a joinder agreement) and WS are parties to the Agreement
and Plan of Reorganization dated as of the date hereof (as amended from time to

respect to the Company securities that they will receive in connection with the
LISN Merger (as defined in the Reorganization Agreement). Orius and the Existing
Orius Stockholders execute this Agreement to induce LISN, WS and the other
Coinvestors to enter into the Reorganization Agreement and to consummate the
transactions contemplated thereby. Pursuant to this Agreement, the parties
hereto have agreed, among other things, (i) to restrict the sale, assignment,
transfer, encumbrance or other disposition of the Stockholder Shares and (ii) to
provide for certain rights and obligations in respect thereto.


<PAGE>   7


                  NOW, THEREFORE, the parties to this Agreement hereby agree as
follows, effective as of the Effective Time:


                  SECTION 1. COVENANTS, REPRESENTATIONS AND WARRANTIES

                  Each Stockholder covenants, represents and warrants that, (i)
as of the Effective Time, such Stockholder will continue to be the record and
beneficial owner of the Stockholder Shares issued to such Stockholder in the
transactions contemplated in the Reorganization Agreement (and, in the case of
each Former Orius Stockholder, such Stockholder will continue to be the record
and beneficial owner of the Orius common stock which such Stockholder held
immediately prior to such transactions and which such Stockholder did not
surrender to the Company in an exchange pursuant to the Reorganization
Agreement), in each case free and clear of all liens, charges or encumbrances
(except (x) Liens to secure obligations under an Orius Put Agreement and an
Orius Call Agreement with respect to those Stockholder Shares which are subject
to such agreements, and (y) to the extent that any such Stockholder Shares are
subject to cancellation by the Company pursuant to indemnification obligations
of such Stockholder under Section 7 of the Reorganization Agreement); (ii) this
Agreement has been duly authorized, executed and delivered by such Stockholder
and constitutes the valid and binding obligation of such Stockholder,
enforceable in accordance with its terms, subject to bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting the
rights and remedies of creditors and secured parties and general principles of
equity; and (iii) such Stockholder has not granted and is not a party to any
proxy, voting trust or voting agreement or any agreement which is inconsistent
with, conflicts with or violates any provision of this Agreement. No holder of
Stockholder Shares shall grant any proxy or become party to any voting trust,
voting agreement or any agreement which is inconsistent with, conflicts with or
violates any provision of this Agreement.


              PROVISIONS RELATING TO TRANSFER; SALE OF THE COMPANY;
                       PUBLIC OFFERING; PREEMPTIVE RIGHTS

                  SECTION 2. RESTRICTIONS ON TRANSFER OF STOCKHOLDER SHARES

                  2A. RESTRICTIONS ON TRANSFER. No holder of Stockholder Shares
shall sell, transfer, assign, pledge or otherwise directly or indirectly dispose
of (a "Transfer") any interest in its Stockholder Shares, except pursuant to and
in accordance with the provisions of Section 2B, 2C or 3 or pursuant to a Public
Sale or an Exempt Transfer (as defined in Section 2D). At least thirty days
prior to making any Transfer of any Stockholder Shares (other than a Public Sale
or an Exempt Transfer), the transferring Stockholder (the "Transferring
Stockholder") shall deliver a written notice (the "Sale Notice") to the Company
and the other Stockholders (the "Other Stockholders"). The Sale Notice shall
disclose in reasonable detail the proposed number or principal amount, as
applicable, of each type or class of Stockholder Shares (the "Transfer Shares")
to be transferred, the proposed terms and conditions of the Transfer, including
proposed price by class or type of each of such Stockholder Shares to be
transferred, and the identity of the prospective transferee(s). Such prospective
transferee(s) must be reasonably acceptable to the holders of a majority of the
WS

                                       -4-

Shares, provided that any such transferee will be deemed to be acceptable to
such holders unless such holders provide notice to the contrary to the
Transferring Stockholder within 10 days of receipt of the Sale Notice by the
Other Stockholders. The purchase price specified in any Sale Notice shall be
payable solely in cash at the closing of the transaction, and no Stockholder
Shares may be pledged without the prior written consent of the holders of a
majority of the WS Shares, which consent may not be unreasonably withheld. No
Transfer shall be consummated prior to the earlier of (i) the date on which the
parties to the Transfer have been finally determined pursuant to Section 2B or
2C and (ii) the date of expiration of the 30-day period (the "Election Period")
following the delivery to the Company and the Other Stockholders of the Sale
Notice applicable to such Transfer.

                  2B. FIRST REFUSAL RIGHT. The Company may elect to purchase all
or any portion of the Transfer Shares at the price and on the terms specified in
the Sale Notice by delivering written notice of such election to the
Transferring Stockholder and the holders of Investor Shares as soon as practical
but in any event within ten (10) days after the delivery of the Sale Notice. If
the Company has not elected to purchase all of such Transfer Shares within such
10-day period, then unless the holders of a majority of the WS Shares direct
otherwise by written notice to the Company, the holders of Investor Shares may
elect to purchase all, but not less than all, of such Transfer Shares which the
Company has not elected to purchase (the "Available Shares"), at the price and
on the terms and conditions specified in the Sale Notice by delivering written
notice of such election to the Transferring Stockholder as soon as practical but
in any event within twenty (20) days after delivery of the Sale Notice. If more
than one holder of Investor Shares elects to purchase the Available Shares, the
Available Shares will be allocated among such electing holders pro rata
according to the number of Stockholder Shares on a Fully Diluted Basis owned by
such electing holders. If the Company or the holders of Investor Shares have
elected to purchase any Transfer Shares pursuant to this Section 2B, such
Transfer(s) shall be consummated as soon as practical after the delivery of the
election notice(s) to the Transferring Stockholder, but in any event within
fifteen (15) days after the expiration of the Election Period. To the extent
that the Company and the holders of Investor Shares have not elected to
purchase, collectively, all of the Transfer Shares, the Transferring Stockholder
may, during the 90-day period following the expiration of the Election Period
(but not at any time thereafter) and subject to the provisions of Section 2C
below, transfer pursuant to this Section 2B all of the Transfer Shares specified
in the Sale Notice to the transferee(s) identified in the Sale Notice for (i) an
amount of cash no less than the price specified in the Sale Notice and (ii)
other terms no more favorable to the transferee(s) thereof than specified in the
Sale Notice. Notwithstanding anything herein to the contrary, as used in this
Section 2B, the term "Transfer Shares" shall in no event include Investor
Transfer Shares unless such Transfer Shares are being transferred by an Investor
to any other Stockholder (other than an Investor).

                  2C. PARTICIPATION RIGHTS.

                  (i) Each Stockholder may elect to participate in a Transfer of
any class of Investor Transfer Shares contemplated in a Sale Notice by
delivering written notice of such election to the Transferring Stockholder
within thirty (30) days after delivery of the Sale Notice. If any Other
Stockholders elect to participate in such Transfer (such Other Stockholders
being referred to as the "Participating Stockholders"), each of the Transferring
Stockholder and the Participating Stockholders shall be entitled to sell in the
contemplated Transfer, at the same price and on the same terms, a number of
Stockholder Shares of such class (with each series or class of Common Stock


                                       -5-

<PAGE>   9


being considered one and the same class for this purpose) (the "Participating
Shares") equal to the product of (A) the quotient determined by dividing the
number of Stockholder Shares of such class held by such Person, by the number of
Stockholder Shares held by the Transferring Stockholder and the Participating
Stockholders and (B) the aggregate number of Transfer Shares of such class to be
sold in the contemplated Transfer; provided each Other Stockholder selling
shares of Common Stock in such Transfer shall be entitled to include in such
Transfer, in addition to such shares of Common Stock, a Proportionate Amount of
shares of Preferred Stock and Junior Notes (and in such event the shares of
Preferred Stock and Junior Notes which an Other Stockholder elects to include in
such Transfer, in accordance with this proviso, shall be deemed to be
Participating Shares).

                  (ii)  For purposes of this Section 2C:

                        (a) Common Stock issuable upon exercise of employee
                            stock options which have not vested and become
                            exercisable, and Common Stock held subject to
                            vesting (i.e., to the extent subject to possible
                            repurchase by the Company at less than fair market
                            value), shall be deemed not to be Stockholder
                            Shares;

                        (b) for purposes of determining the amount of each class
                            and type of Stockholder Shares which any Stockholder
                            is entitled to include in any Transfer, all
                            Stockholder Shares held by any Permitted Transferee
                            of any Other Stockholder shall be deemed held by
                            such Other Stockholder himself or itself (and not by
                            such transferee), provided that such Other
                            Stockholder may assign its rights under this Section
                            2C to its Permitted Transferees in respect of the
                            Stockholder Shares that it previously transferred to
                            such transferees;

                        (c) in any Transfer which includes more than one class
                            of Stockholder Shares, the price allocable to each
                            class of Stockholder Shares for purposes of the
                            foregoing shall be determined by allocating the
                            aggregate purchase price so that (x) the price
                            allocable to each Junior Notes is not less than the
                            Liquidation Value thereof at such time, and (y) the
                            price allocable to each share of Preferred Stock is
                            not less than the sum of (1) the Liquidation Value
                            thereof at such time, plus (2) the price payable in
                            such transaction in respect of each share of Common
                            Stock (and/or fraction thereof) multiplied by the
                            number of shares of Common Stock which would be
                            issued upon conversion of such share of Preferred
                            Stock if all conditions set forth in the Company's
                            certificate of incorporation to the conversion of
                            such share were satisfied and such share of
                            Preferred Stock were converted at such time; and


                                       -6-

<PAGE>   10


                        (d) "Proportionate Amount" means, for each share of
                            Common Stock included in such Transfer, shares of
                            Preferred Stock and Junior Notes in the initial
                            principal amount of $ .1

                  (iii) Each Transferring Stockholder will use reasonable
efforts to obtain the agreement of the prospective transferee(s) to the
participation of the Participating Stockholders in any contemplated Transfer,
and shall not consummate any such Transfer unless each Participating Shareholder
is permitted to sell Participating Shares in such Transfer in the amount and on
the terms set forth in this Section 2C (provided that if the prospective
transferee declines to allow the participation of any Participating Stockholder,
as an alternative the Transferring Stockholder may consummate the proposed
Transfer so long as contemporaneously therewith the Transferring Stockholder
purchases from such Participating Stockholder all of such Participating
Stockholder's Participating Shares at the same price and on the same terms as
the Transferring Stockholder transferred Stockholder Shares to such transferee).
Each Participating Stockholder transferring Participating Shares pursuant to
this Section 2C shall pay (x) its own expenses incurred by such Participating
Stockholder in connection with the Transfer and (y) its pro rata share
(according to holdings of Common Stock) of the expenses incurred by the
Transferring Stockholder in connection with such transfer, and each such
Stockholder shall be obligated to join in any indemnification or other
obligations that the Transferring Stockholder agrees to provide in connection
with such transfer (other than any such obligations that relate specifically to
a particular Participating Stockholder, such as indemnification with respect to
representations and warranties given by a Participating Stockholder regarding
such Stockholder's title to and ownership of Participating Shares).

                  2D.   PERMITTED TRANSFERS. The restrictions set forth in this
Section 2 shall not apply to the following transfers to the following
transferees:

                  (i)   subject to the paragraphs below, any Transfer of
Stockholder Shares by any Stockholder to any of its Affiliates,

                  (ii)  in the case of an individual, a Transfer of Stockholder
Shares by any Stockholder pursuant to the laws of descent and distribution or
among such Stockholder's Family Group,

                  (iii) Transfer of Stockholder Shares to Orius pursuant to an
Orius Put Agreement, an Orius Call Agreement and/or a Pledge and Voting
Agreement,

                  (iv)  an Approved Sale, and

                  (v)   in the case of any Stockholder which is not an
individual, to a successor corporation or other successor entity as a result of
a merger or consolidation with, or a sale of all or

(1) The Company's Chief Financial Officer is authorized by all parties hereto to
insert numbers in these blanks upon final determination of all amounts pursuant
to Section 1E of the Reorganization Agreement. The amounts inserted shall
reflect the proportions in which Common Stock, Preferred Stock and Junior Notes
are issued pursuant to the Reorganization Agreement to Orius Stockholders
pursuant to the Securities Only Joinder Agreements in exchange for shares of
Orius Common Stock (as such capitalized terms are defined in the Reorganization
Agreement).

substantially all of the assets of, such Stockholder or a transfer to one or
more of its Affiliates or, if a general or limited partnership, in connection
with the liquidation and dissolution of such partnership.

Not less than 20 days prior to any Transfer of Stockholder Shares pursuant to
the foregoing clause (i) or (ii) of the previous sentence, the proposed
transferee will deliver a written notice to the Company, which notice will
disclose in reasonable detail the identity of such transferee. No Transfer shall
be permitted pursuant to clause (i) above of this Section 2D unless such
transferee shall be acceptable to the holders of a majority of WS Shares. In
addition, notwithstanding anything to the contrary herein, the restrictions
contained in this Agreement will continue to be applicable to the Stockholder
Shares following any Transfer, and the transferee of such Stockholder Shares
shall agree in writing to be bound by the provisions of this Agreement.
Notwithstanding the foregoing, no party hereto shall avoid the provisions of
this Agreement by making one or more transfers to one or more Permitted
Transferees and then disposing of all or any portion of such party's interest in
any such Permitted Transferee. Any Transfer permitted pursuant to this Section
2D is referred to herein as an "Exempt Transfer".

                  2E. TERMINATION OF RESTRICTIONS. The restrictions set forth in
this Section 2 shall continue with respect to each Stockholder Share until the
earlier of (i) the date on which such Stockholder Share has been transferred in
a Public Sale and (ii) the consummation of a Change of Control.


                  SECTION 3. SALE OF THE COMPANY

                  3A. APPROVED SALE. If the holders of a majority of WS Shares
approve a Sale of the Company (an "Approved Sale"), each holder of Stockholder
Shares will vote for, consent to and will not object or otherwise impede
consummation of the Approved Sale.

                  3B. REQUIRED ACTIONS. If the Approved Sale is structured as
(A) a merger or consolidation, each holder of Stockholder Shares shall waive any
dissenter's rights, appraisal rights or similar rights in connection with such
merger or consolidation, (B) a sale of stock, each holder of Stockholder Shares
shall agree to sell all of its Stockholder Shares and rights to acquire
Stockholder Shares on the terms and conditions so approved, or (C) as a sale of
assets, each holder of Stockholder Shares shall vote in favor of such sale and
any subsequent liquidation of the Company or other distribution of the proceeds
therefrom. Each holder of Stockholder Shares shall take all necessary or
desirable actions in connection with the consummation of the Approved Sale
reasonably requested by the holders of a majority of the WS Shares. In
furtherance of the foregoing, (I) each holder of Stockholder Shares will take
all necessary or desirable actions reasonably requested by the holders of a
majority of the WS Shares in connection with the consummation of the Approved
Sale of the Company and (II) each holder of Stockholder Shares will make the
same representations, warranties, indemnities and agreements as to each other
holder, including without limitation, voting to approve such transaction and
executing the applicable purchase agreement (the "Company Reps"). In any
Approved Sale, each holder of Stockholder Shares shall not be required to make
indemnification payments in connection with any Approved Sale except pro rata in
accordance with such holder's ownership of Common Stock (or, after payment of
indemnification



                                       -8-

<PAGE>   12

payments in an amount in excess of the net proceeds received in such Approved
Sale in respect of Common Stock, pro rata in accordance with such holder's
ownership of Preferred Stock or, after payment of indemnification payments in an
amount in excess of the net proceeds received in such Approved Sale in respect
of Preferred Stock, pro rata in accordance with such holder's ownership of
Junior Notes), unless the applicable agreements relating to such Approved Sale
require the other holders of such Stockholder Shares to indemnify such holder
against, and hold such holder harmless from, amounts for which such holder may
become liable in excess of the maximum amount contemplated by the first clause
of this sentence; provided that the foregoing limitation shall not apply to any
indemnity by a Stockholder for breach by such Stockholder of any representation
or warranty relating solely to the authorization, execution or delivery by such
Stockholder of the relevant agreements or as to such Stockholder's ownership of
securities sold by such Stockholder thereunder or for breach of any agreement by
such Stockholder relating solely to its own conduct; and provided, further that
in no event shall any Stockholder be liable in respect of any indemnity
obligations pursuant to any Approved Sale in an aggregate amount in excess of
the total consideration payable to such Stockholder in such Approved Sale.

                  3C. CONDITIONS TO STOCKHOLDERS' OBLIGATIONS. The obligations
of the holders of Stockholder Shares with respect to an Approved Sale are
subject to the satisfaction of the following conditions: (i) upon the
consummation of the Approved Sale, each holder of Stockholder Shares will
receive the same form of consideration and the same portion of the aggregate
consideration that such holders of Stockholder Shares would have received if
such aggregate consideration had been distributed by the Company in complete
liquidation pursuant to the rights and preferences set forth in the Certificate
of Incorporation as in effect immediately prior to such Approved Sale; (ii) if
any holders of a class of Stockholder Shares are given an option as to the form
and amount of consideration to be received, each holder of such class of
Stockholder Shares will be given the same option; and (iii) each holder of then
currently exercisable rights to acquire shares of a class of Stockholder Shares
will be given an opportunity to exercise such rights prior to the consummation
of the Approved Sale and participate in such sale as holders of such class of
Stockholder Shares.

                  3D. RULE 506 TRANSACTION. If the Company or the holders of the
Company's securities enter into any negotiation or transaction for which Rule
506 (or any similar rule then in effect) promulgated by the Securities Exchange
Commission may be available with respect to such negotiation or transaction
(including a merger, consolidation or other reorganization), the holders of
Stockholder Shares will, at the request of the Company, appoint a purchaser
representative (as such term is defined in Rule 501) reasonably acceptable to
the Company. If any holder of Stockholder Shares appoints a purchaser
representative designated by the Company, the Company will pay the fees of such
purchaser representative, but if any holder of Stockholder Shares declines to
appoint the purchaser representative designated by the Company such holder will
appoint another purchaser representative, and such holder will be responsible
for the fees of the purchaser representative so appointed.

                  3E. EXPENSES OF APPROVED SALE. Holders of Stockholder Shares
will bear their pro rata share (based upon holdings on a Fully Diluted Basis) of
the costs of any sale of Stockholder Shares pursuant to an Approved Sale to the
extent such costs are incurred for the benefit of all holders of Stockholder
Shares and are not otherwise paid by the Company or the acquiring party.


                                       -9-

<PAGE>   13


For purposes of this Section 3E, costs incurred in exercising reasonable efforts
to take all necessary actions in connection with the consummation of an Approved
Sale in accordance with Section 3A shall be deemed to be for the benefit of all
holders of Stockholder Shares. Costs incurred by any holder of Stockholder
Shares on its own behalf will not be considered costs of the transaction
hereunder and will be the responsibility of such holder.


                  SECTION 4. LIMITED PREEMPTIVE RIGHTS

                  4A. OFFERING. If the Company issues or sells or authorizes the
issuance or sale of any of its equity securities or any securities containing
options or rights to acquire equity securities (other than as a dividend on the
then outstanding Common Stock or pursuant to exercise, conversion or exchange of
securities or rights previously issued by the Company subject to this Section 4
or, outstanding on the date hereof or issued in accordance with this clause) to
WS or any of its Affiliates ("New Securities"), the Company shall offer to each
holder of Stockholder Shares of the same class and type as the New Securities
being issued or sold a percentage of such New Securities equal to the percentage
result of the quotient determined by dividing (A) the number of Stockholder
Shares held by such holder, by (B) the number of outstanding Stockholder Shares
on a Fully Diluted Basis. Each such holder of Stockholder Shares shall be
entitled to purchase such New Securities at the most favorable price and on the
most favorable terms as such New Securities are to be offered to WS or any
Affiliate of WS; provided that if WS, or any Affiliate of WS participating in
such purchase of New Securities, is required in connection therewith also to
purchase other securities of the Company, the holders of Stockholder Shares
exercising their rights pursuant to this Section shall also be required to
purchase such other securities on the same economic terms and conditions as
those on which WS or such Affiliate of WS participating in such purchase is
required to purchase such other securities (e.g., such holder shall be required
to purchase the same types and classes of other securities, in the same
proportions relative to their purchases of New Securities and at the same unit
prices). For example, if the Company offers to sell to WS shares of Common Stock
and requires that, as part of such purchase, WS also purchase a Proportionate
Amount of Preferred Stock and Junior Notes, Stockholders exercising rights to
purchase shares of Common Stock pursuant to this Section 4A would be obligated
also to purchase the corresponding Proportionate Amount of Preferred Stock and
Junior Notes, in each case at the same price per share of Preferred Stock and
per dollar in principal amount of Junior Notes as paid by WS. Each holder of
Stockholder Shares participating in such purchase shall also be obligated to
execute agreements in the form presented to such holder by the Company, so long
as such agreements are substantially similar to those to be executed by WS
(without taking into consideration any rights which WS may obtain which do not
entitle WS to a higher economic return on the New Securities than the economic
return to which the other Stockholders participating in such transaction will be
entitled with respect to New Securities). The purchase price for all New
Securities offered to each holder of Stockholder Shares shall be payable in cash
by wire transfer of immediately available funds to an account designated by the
Company.

                  4B. ELECTION NOTICE. In order to exercise its purchase rights
hereunder, each holder of Stockholder Shares must deliver a written notice (an
"Election Notice") to the Company describing its election hereunder. Such
Election Notice must be delivered to the Company during the 30-day period (the
"Offering Period") following such holder's receipt of written notice from the




                                      -10-

<PAGE>   14
Company describing in reasonable detail the type, class and number of New
Securities being offered, the purchase price thereof, the payment terms and such
holder's percentage allotment.


                  4C. EXPIRATION OF OFFERING PERIOD. Upon the expiration of the
Offering Period and during the 90-day period immediately thereafter, the Company
shall be entitled to sell to WS or any Affiliate of WS such New Securities which
any holder of Stockholder Shares has not elected to purchase on terms and
conditions no more favorable to WS or any Affiliate of WS than those offered to
holders of Stockholder Shares pursuant to Section 4A. Any New Securities offered
or sold by the Company to WS or any Affiliate of WS after such 90-day period
must be reoffered to each holder of Stockholder Shares pursuant to the terms of
this Section 4.

                  4D. TERMINATION. The rights under this Section 4 shall
terminate upon consummation of a Public Offering or a Sale of the Company.


                  SECTION 5. PUBLIC OFFERING

                  In the event that the Board and the holders of a majority of
the WS Shares approve an initial Public Offering, the holders of Stockholder
Shares will use reasonable efforts to take all necessary or desirable actions in
connection with the consummation of such Public Offering. In the event that such
Public Offering is an underwritten offering and the managing underwriters advise
the Company in writing that in their opinion the existing capital structure of
the Company will adversely affect the marketability of the offering, each holder
of Stockholder Shares will consent to and vote for a recapitalization,
reorganization and/or exchange of the Stockholder Shares into securities that
the managing underwriters, the Board and the holders of a majority of WS Shares
(in consultation with the Existing Orius Stockholders so long as they remain
involved in the Company's business) find acceptable and will take all other
necessary or desirable actions in connection with the consummation of the
recapitalization, reorganization and/or exchange; provided that the resulting
securities reflect and are consistent with the rights and preferences among the
outstanding classes of securities set forth in the Certificate of Incorporation
and the terms of the Junior Notes as in effect immediately prior to such
recapitalization, reorganization or exchange.


                  SECTION 6. LEGEND

                  Each certificate evidencing Stockholder Shares and each
certificate issued in exchange for or upon the transfer of any Stockholder
Shares (if such shares remain Stockholder Shares as defined herein after such
Transfer) shall be stamped or otherwise imprinted with a legend in substantially
the following form:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  CERTAIN TRANSFER RESTRICTIONS PURSUANT TO AN INVESTOR RIGHTS

                  SUCH SECURITIES (THE "COMPANY") AND CERTAIN OF THE COMPANY'S

                  COMPANY'S CHIEF FINANCIAL OFFICER."


                  The Company shall imprint such legend on certificates
evidencing Stockholder Shares outstanding prior to the date hereof. The legend
set forth above shall be promptly removed from the certificates evidencing any
shares which cease to be Stockholder Shares.


                  SECTION 7. TRANSFER

                  Prior to Transferring any Stockholder Shares (other than in a
Public Sale or in an Approved Sale) to any person or entity, the Transferring
Stockholder shall cause the prospective transferee to execute and deliver to the
Company and the other Stockholders a counterpart of this Agreement.


                  SECTION 8. BOARD OF DIRECTORS; VOTING

                  8A. COMPOSITION OF THE BOARD. From and after the effectiveness
of this Agreement and until the provisions of this Section 8 cease to be
effective, each Stockholder shall vote all of his, her or its Stockholders
Shares and any other voting securities of the Company over which such
Stockholder has voting control and shall take all other necessary or desirable
actions within his, her or its control (whether in the capacity as a

otherwise, and including, without limitation, attendance at meetings in person
or by proxy for purposes of obtaining a quorum and execution of written consents
in lieu of meetings), and the Company shall take all necessary and desirable
actions within its control (including, without limitation, calling special board

                  (i)   the authorized number of directors on the Company's
board of directors (the "Board") shall be established at seven directors or such
higher number as may be designated by WS by written notice to the Company;

                  (ii)  the following persons shall be elected to the Board:

                            shall be William J. Mercurio (the "CEO Director");

                            of the Existing Orius Stockholders Shares, which
                            person must be a senior executive of the Company or

                            (d) until such time as Chisholm Partners III, L.P.
                            ("Chisholm") owns less than 50% of the Stockholder
                            Shares held by Chisholm at the Effective Time) and

                            each individually, a "WS Director");


                  (iii) the composition of the board of directors of each of the
Company's Subsidiaries (each, a "Sub Board") shall be as determined by the
Board, and initially shall be the same as in existence as of the date hereof,
provided that, effective immediately upon the Effective Time, a representative
designated by the holders of a majority of the WS Shares shall replace the
representative on any Sub Board heretofore designated by HIG Cable, Inc. or any
Affiliate of HIG Cable, Inc.;

                  (iv)  the removal from the Board or Sub Board (with or without
cause) of the Executive Director shall be only upon the written request of the
holders of a majority of the Existing Orius Stockholders Shares and the removal
of the WS Nominated Director shall be only upon the written request of the
holders of a majority of the WS Shares; provided that if the CEO Director,
Executive Director or the WS Nominated Director ceases to be an employee of the
Company and its Subsidiaries, such person shall be removed as a director upon
termination of such person's employment;

                  (v)   in the event that any person designated as a director
hereunder for any reason ceases to serve as a member of the Board or a Sub Board
during such person's term of office, the resulting vacancy on the Board or the
Sub Board shall be filled by a representative designated by the person or
persons originally entitled to designate such director pursuant to Section
8A(ii) above; and

                  (vi)  if any party fails to designate a representative to fill
a directorship pursuant to the terms of this Section 8A, the election of a
person to such directorship shall be accomplished in accordance with the
Company's bylaws and applicable law.

                  8B. BOARD MEETING EXPENSES. The Company shall pay all
out-of-pocket expenses incurred by each director in connection with attending

                                      -13-

<PAGE>   17
written consent, in the manner in which the holders of a majority of the WS
Shares directs in connection with the approval of any amendment or amendments to
the Company's articles of incorporation or bylaws, the merger, share exchange,
combination or consolidation of the Company with any other Person or Persons,
the sale, lease or exchange of all or substantially all of the property and
assets of the Company and its Subsidiaries on a consolidated basis, and the
reorganization, recapitalization, liquidation, dissolution or winding-up of any
of the Company and its Subsidiaries; provided, however that no such action shall
(a) be inconsistent with the terms of this Agreement, or (b) have a material
adverse effect on any Stockholder's rights or interests in respect of any
Stockholder Shares, if such effect would be borne disproportionately by such
Stockholder relative to the effect on the rights or interests of other
Stockholders in respect of holdings of Stockholder Shares of the same class.


            PROVISIONS RELATING TO REGISTRATION OF STOCKHOLDER SHARES


                  SECTION 9. DEMAND REGISTRATIONS

                  9A. REQUESTS FOR REGISTRATION. At any time the holders of a
majority of the WS Registrable Securities may request registration under the
Securities Act (a "Demand Registration") of all or any portion of its
Registrable Securities on Form S-1 or any similar long-form registration
("Long-Form Registrations") or, if available, on Form S-2 or S-3 or any similar
short-form registration ("Short-Form Registrations"). Each request for a Demand
Registration shall specify the approximate number of Registrable Securities
requested to be registered and the anticipated per share price range for such
offering. Within ten days after receipt of any such request, the Company will
give written notice of such requested registration to all other holders of
Registrable Securities and, subject to Section 9D below, will include in such
registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within 15 days after the receipt
of the Company's notice.

                  9B. LONG-FORM REGISTRATIONS. The holders of a majority of the
WS Registrable Securities will be entitled to request an unlimited number of
Long-Form Registrations in which the Company will pay all Registration Expenses.

                  9C. SHORT-FORM REGISTRATIONS. In addition to the Long-Form
Registrations provided pursuant to Section 9B, the holders of a majority of the
WS Registrable Securities will be entitled to request unlimited Short-Form
Registrations in which the Company will pay all Registration Expenses. Demand
Registrations will be Short-Form Registrations whenever the Company is permitted
to use any applicable short form. After the Company has become subject to the
reporting requirements of the Securities Exchange Act, the Company will use its
best efforts to make Short- Form Registrations available for the sale of
Registrable Securities.

                  9D. PRIORITY ON DEMAND REGISTRATIONS. The Company will not
include in any Demand Registration any securities which are not Registrable
Securities without the prior written consent of the holders of a majority of the
WS Registrable Securities. If a Demand Registration is an underwritten offering
and the managing underwriters advise the Company in writing that in their


                                      -14-

<PAGE>   18


opinion the number of Registrable Securities and, if permitted hereunder, other
securities requested to be included in such offering exceeds the number of
Registrable Securities and other securities, if any, which can be sold in an
orderly manner in such offering within a price range reasonably acceptable to
the holders of a majority of the Registrable Securities initially requesting
registration, the Company will include in such registration, if any, (i) first,
the Registrable Securities requested to be included in such registration by the
holders thereof, pro rata among such holders on the basis of the number of
shares of Registrable Securities owned by each such holder, and (ii) second, the
other securities requested to be included which in the opinion of such
underwriters can be sold in an orderly manner within the price range of such
offering.

                  9E. RESTRICTIONS ON DEMAND REGISTRATIONS. The Company will not
be obligated to effect any Demand Registration within six months after the
effective date of a previous Demand Registration. The Company may postpone for
up to six months the filing or the effectiveness of a registration statement for
a Demand Registration if the Company's board of directors determines that such
Demand Registration would reasonably be expected to have an adverse effect on
any proposal or plan by the Company or any of its Subsidiaries to engage in any
acquisition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or similar transaction; provided that, in
such event, the holders of Registrable Securities initially requesting such
Demand Registration will be entitled to withdraw such request.

                  9F. SELECTION OF UNDERWRITERS. The holders of a majority of
the WS Registrable Securities will have the right to select the investment
banker(s) and manager(s) to administer the offering, subject to the Company's
approval which will not be unreasonably withheld.

                  9G. OTHER REGISTRATION RIGHTS. Except as provided in this
Agreement, the Company will not grant to any Persons the right to request the
Company to register any equity securities of the Company, or any securities
convertible or exchangeable into or exercisable for such securities, without the
prior written consent of the holders of a majority of the WS Registrable
Securities.

                  9H. DEMAND REGISTRATION EXPENSES. The Registration Expenses in
connection with any Demand Registration will be paid by the Company, including
the reimbursement of the holders of Registrable Securities included in such
registration for the reasonable fees and disbursements of one counsel chosen by
the holders of a majority of the Registrable Securities included in such
registration.


                  SECTION 10. PIGGYBACK REGISTRATIONS

                  10A. RIGHT TO PIGGYBACK. Whenever the Company proposes to
register any of its securities under the Securities Act (other than (i) in
connection with the Company's initial public offering of Common Stock, (ii)
pursuant to a Demand Registration or (iii) pursuant to a registration on Form
S-4 or S-8 or any successor or similar forms) and the registration form to be
used may be used for the registration of Registrable Securities (a "Piggyback
Registration"), the Company will give prompt written notice to all holders of
Registrable Securities of its intention to effect such a registration and will
use its reasonable best efforts to include in such registration all Registrable


                                      -15-

<PAGE>   19

Securities with respect to which the Company has received written requests for
inclusion therein within 15 days after the receipt of the Company's notice.


                  10B. PIGGYBACK EXPENSES. The Registration Expenses of the
holders of Registrable Securities will be paid by the Company in all Piggyback
Registrations.

                  10C. PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback
Registration is an underwritten primary registration on behalf of the Company,
and the managing underwriters advise the Company in writing that in their
opinion the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering in an orderly manner
within a price range acceptable to the Company, the Company will include in such
registration (i) first, the securities the Company proposes to sell, (ii)
second, the Registrable Securities requested to be included in such
registration, pro rata among the holders of such Registrable Securities on the
basis of the number of shares owned by each such holder, and (iii) third, other
securities requested to be included in such registration.

                  10D. OTHER REGISTRATIONS. If the Company has previously filed
a registration statement with respect to Registrable Securities pursuant to
Section 9 or pursuant to this Section 10, and if such previous registration has
not been withdrawn or abandoned, the Company will not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act (except on Form S-4 or S-8 or any successor form), whether on
its own behalf or at the request of any holder or holders of such securities,
until a period of at least six months has elapsed from the effective date of
such previous registration.

                  10E. POSTPONEMENT OR WITHDRAWAL. Notwithstanding the
foregoing, the Company may postpone or withdraw any registration statement
referred to in this Section 10 without incurring any liability to holders of
Registrable Securities.


                  SECTION 11. HOLDBACK AGREEMENTS

                  11A. AGREEMENT OF HOLDERS OF REGISTRABLE SECURITIES. Each
holder of Registrable Securities will not effect any public sale or distribution
(including sales pursuant to Rule 144) of equity securities of the Company, or
any securities, options or rights convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and the 180-day
period beginning on the effective date of any underwritten Demand Registration
or any underwritten Piggyback Registration (except as part of such underwritten
registration), unless the underwriters managing the registered public offering
otherwise agree.

                  11B. COMPANY AGREEMENT. The Company will (i) not effect any
public sale or distribution of its equity securities, or any securities
convertible into or exchangeable or exercisable for such securities, during the
seven days prior to and during the 180-day period beginning on the effective
date of any underwritten Demand Registration or any underwritten Piggyback
Registration (except as part of such underwritten registration or pursuant to
registrations on Form S-4 or S-8 or any successor form), unless the underwriters
managing the registered public offering otherwise


                                      -16-

<PAGE>   20


agree, and (ii) cause each holder of shares of Common Stock, or any securities
convertible into or exchangeable or exercisable for shares of Common Stock,
purchased from the Company at any time after the date of this Agreement (other
than in a registered public offering) to agree not to effect any public sale or
distribution (including sales pursuant to Rule 144) of any such securities
during such period (except as part of such underwritten registration, if
otherwise permitted), unless the underwriters managing the registered public
offering otherwise agree.


                  SECTION 12. REGISTRATION PROCEDURES

                  Whenever the holders of Registrable Securities have requested
that any Registrable Securities be registered pursuant to this Agreement, the
Company will use its best efforts to effect the registration and the sale of
such Registrable Securities in accordance with the intended method of
disposition thereof, and pursuant thereto the Company will as expeditiously as
reasonably possible:

                  (i)   prepare and file with the Securities and Exchange
Commission a registration statement with respect to such Registrable Securities
and thereafter use its best efforts to cause such registration statement to
become effective (provided that before filing a registration statement or
prospectus or any amendments or supplements thereto, the Company will furnish to
the counsel selected by the holders of a majority of the Registrable Securities
initiating such registration statement copies of all such documents proposed to
be filed, which documents will be subject to review of such counsel);

                  (ii)  notify each holder of Registrable Securities of the
effectiveness of each Registration Statement filed hereunder and prepare and
file with the Securities and Exchange Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective for a period
of either (i) not less than six months (subject to extension pursuant to Section
15) or, if such registration statement relates to an underwritten offering, such
longer period as in the opinion of counsel for the underwriters a prospectus is
required by law to be delivered in connection with sales of Registrable
Securities by an underwriter or dealer or (ii) such shorter period as will
terminate when all of the securities covered by such registration statement have
been disposed of in accordance with the intended methods of disposition by the
seller or sellers thereof set forth in such registration statement (but in any
event not before the expiration of any longer period required under the
Securities Act), and to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement until such time as all of such securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof set forth in such registration statement; provided that the Company
shall not be obligated to maintain the effectiveness of any registration
statement for a period of more than twenty-four months from the date on which
the such registration statement initially becomes effective.

                  (iii) furnish to each seller of Registrable Securities such
number of copies of such registration statement, each amendment and supplement
thereto, the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such

                                      -17-

<PAGE>   21

seller may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such seller;

                  (iv)   use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller (provided that the Company will not be required
to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this subparagraph, (ii) subject itself
to taxation in any such jurisdiction or (iii) consent to general service of
process in any such jurisdiction);

                  (v)    notify each seller of such Registrable Securities, at
any time when a prospectus relating thereto is required to be delivered under
the Securities Act, upon discovery that, or upon the discovery of the happening
of any event as a result of which, the prospectus included in such registration
statement contains an untrue statement of a material fact or omits any fact
necessary to make the statements therein not misleading in the light of the
circumstances under which they were made, and, at the request of any such
seller, the Company will prepare and furnish to such seller a reasonable number
of copies of a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus will
not contain an untrue statement of a material fact or omit to state any fact
necessary to make the statements therein not misleading in the light of the
circumstances under which they were made;

                  (vi)   cause all such Registrable Securities to be listed on
each securities exchange or market on which similar securities issued by the
Company are then listed;

                  (vii)  provide a transfer agent and registrar for all such
Registrable Securities not later than the effective date of such registration
statement;

                  (viii) enter into such customary agreements (including
underwriting agreements in customary form) as may be requested by the
underwriters and take all such other actions as the holders of a majority of the
Registrable Securities being sold or the underwriters, if any, reasonably
request in order to expedite or facilitate the disposition of such Registrable
Securities (including, without limitation, effecting a stock split or a
combination of shares);

                  (ix)   make available for inspection by any seller of
Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement and any attorney, accountant or other
agent retained by any such seller or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors, employees and independent accountants to
supply all information reasonably requested by any such seller, underwriter,
attorney, accountant or agent in connection with such registration statement;

                  (x)    otherwise use its best efforts to comply with all
applicable rules and regulations of the Securities and Exchange Commission, and
make available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve




                                      -18-
<PAGE>   22
months beginning with the first day of the Company's first full calendar quarter
after the effective date of the registration statement, which earnings statement
shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder;

                  (xi) in the event of the issuance of any stop order suspending
the effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Securities included in such registration statement for sale in any
jurisdiction, the Company will use its reasonable best efforts promptly to
obtain the withdrawal of such order;

                  (xii) obtain one or more comfort letters, dated the effective
date of such registration statement (and, if such registration includes an
underwritten public offering, dated the date of the closing under the
underwriting agreement), signed by the Company's independent public accountants
in customary form and covering such matters of the type customarily covered by
comfort letters as the holders of a majority of the Registrable Securities being
sold reasonably request (provided that such Registrable Securities constitute at
least 10% of the securities covered by such registration statement); and

                  (xiii) as required by the Securities Act or by an underwriter,
provide a legal opinion of the Company's outside counsel, dated the effective
date of such registration statement (and, if such registration includes an
underwritten public offering, dated the date of the closing under the
underwriting agreement), with respect to the registration statement, each
amendment and supplement thereto, the prospectus included therein (including the
preliminary prospectus) and such other documents relating thereto in customary
form and covering such matters of the type customarily covered by legal opinions
of such nature.

The Company may require each seller of Registrable Securities as to which any
registration is being effected to furnish the Company such information regarding
such seller and the distribution of such securities as the Company may from time
to time reasonably request in writing.

                  SECTION 13. REGISTRATION EXPENSES

                  13A. COMPANY EXPENSES. All expenses incident to the Company's
performance of or compliance with this Agreement, including, without limitation,
all registration and filing fees, fees and expenses of compliance with
securities or blue sky laws, printing expenses, messenger and delivery expenses,
and fees and disbursements of counsel for the Company and all independent
certified public accountants, underwriters (excluding discounts and commissions)
and other Persons retained by the Company (all such expenses being herein called
"Registration Expenses"), will be borne as provided in this Agreement, except
that the Company will, in any event, pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit or
quarterly review, the expense of any liability insurance and the expenses and
fees for listing the securities to be registered on each securities exchange on
which similar securities issued by the Company are then listed or on the NASD

                                      -19-
<PAGE>   23

                  13B. REIMBURSEMENT. In connection with each Demand
Registration and each Piggyback Registration, the Company will reimburse the
holders of Registrable Securities covered by such registration for the
reasonable fees and disbursements of one counsel chosen by the holders of a
majority of the Registrable Securities initially requesting such registration.
In connection with each Demand Registration and each Piggyback Registration, the
Company shall reimburse the holders of Registrable Securities included in such
registration for the reasonable fees and disbursements of each additional
counsel retained by any holder of Registrable Securities for the purpose of
rendering any legal opinion required by the Company or the managing
underwriter(s) to be rendered on behalf of such holder in connection with any
underwritten Demand Registration or Piggyback Registration.


                  SECTION 14. INDEMNIFICATION

                  14A. INDEMNIFICATION OBLIGATION OF THE COMPANY. The Company
agrees to indemnify and hold harmless, to the extent permitted by law, each
holder of Registrable Securities, its officers and directors and each Person who
controls such holder (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities and expenses caused by (i) any untrue or
alleged untrue statement of material fact contained in any registration
statement, prospectus or preliminary prospectus or any amendment thereof or
supplement thereto or, (ii) any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except in so far as the same are caused by or contained in any
information furnished in writing to the Company by or on behalf of such holder
expressly for use therein or by such holder's failure to deliver a copy of the
registration statement or prospectus or any amendments or supplements thereto
after the Company has furnished such holder with a sufficient number of copies
of the same. In connection with an underwritten offering, the Company will
indemnify such underwriters, their officers and directors and each Person who
controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to the indemnification of the holders
of Registrable Securities.

                  14B. INDEMNIFICATION OF THE COMPANY. In connection with any
registration statement in which a holder of Registrable Securities is
participating, each such holder will furnish to the Company in writing such
information and affidavits as the Company reasonably requests for use in
connection with any such registration statement or prospectus and, to the extent
permitted by law, will indemnify and hold harmless the Company, its directors
and officers and each other Person who controls the Company (within the meaning
of the Securities Act) against any losses, claims, damages, liabilities and
expenses caused by (i) any untrue or alleged untrue statement of material fact
contained in the registration statement, prospectus or preliminary prospectus or
any amendment thereof or supplement thereto or (ii) any omission or alleged
omission of a material fact required to be stated therein or necessary to make
the statements therein not misleading, but only to the extent that such untrue
statement or omission is contained in any information or affidavit so furnished
in writing by or on behalf of such holder; provided that the obligation to
indemnify will be individual to each holder and will be limited to the net
amount of proceeds received by such holder from the sale of Registrable
Securities pursuant to such registration statement.


                                      -20-
<PAGE>   24

                  14C. INDEMNIFICATION PROCEDURES. Any Person entitled to
indemnification hereunder will (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks indemnification
(provided that the failure to give prompt notice shall not impair any Person's
right to indemnification hereunder to the extent such failure has not adversely
affected the indemnifying party) and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

                  14D. OTHER INDEMNIFICATION PROVISIONS. The indemnification
provided for under this Agreement will remain in full force and effect
regardless of any investigation made by or on behalf of the indemnified party or
any officer, director or controlling Person of such indemnified party and will
survive the transfer of securities. The Company and any other indemnifying party
with respect to the matters set forth in Sections 9 through 14 of this Agreement
also agree to make such provisions, as are reasonably requested by any
indemnified party, for contribution to such party in the event the Company's
indemnification is unavailable for any reason.


                  SECTION 15. PARTICIPATION IN UNDERWRITTEN
                              REGISTRATIONS

                  No Person may participate in any registration hereunder which
is underwritten unless such Person (i) agrees to sell such Person's securities
on the basis provided in any underwriting arrangements approved by the Person or
Persons entitled hereunder to approve such arrangements (including, without
limitation, pursuant to the terms of any over-allotment or "green shoe" option
requested by the managing underwriter(s), provided that no holder of Registrable
Securities will be required to sell more than the number of Registrable
Securities that such holder has requested the Company to include in any
registration) and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements. Each Person that is
participating in any registration hereunder agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 12(v) above, such Person will forthwith discontinue the disposition of
its Registrable Securities pursuant to the registration statement until such
Person's receipt of the copies of a supplemented or amended prospectus as
contemplated by such Section 12(v). In the event the Company shall give any such
notice, the applicable time period mentioned in Section 12(ii) during which a
Registration Statement is to remain effective shall be extended by the number of
days during the period from and including the date of the giving of such notice
pursuant to this Section 15 to and including the date when each seller of
Registrable Securities covered by such registration statement shall have
received the copies of the supplemented or amended prospectus contemplated by
Section 12(v).

                  SECTION 16. REINCORPORATION

accrued and unpaid interest on the Junior Notes exchanged therefor (the "Newco
Junior Notes"), and will take all other necessary or desirable actions in
connection with the consummation of the reincorporation of the Company as a
Delaware corporation, and (iv) the Company shall cause Newco to issue to the
holders of Junior Notes the Newco Junior Notes in exchange therefor or, at its
election, to assume all of the Company's obligations under the Junior Notes,
provided that the securities issued by Newco in exchange for or upon conversion
of Stockholder Shares reflect and are consistent with the rights and preferences
among the outstanding classes of Stockholder Shares set forth in the Certificate
of Incorporation and the terms of the Junior Notes as in effect immediately
prior to such merger. Upon consummation of any such merger, Newco shall execute
a counterpart signature page to this Agreement to acknowledge its assumption of
all of the obligations of the Company hereunder, the "Stockholder Shares" as
referred to herein shall mean and include the securities issued upon conversion
of or in exchange for the Stockholder Shares in connection with such merger, as

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT


     THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") is made as
of the 15th day of December, 1999 by and between ORIUS CORP., a Florida
corporation (the "Company") and JOSEPH P. POWERS (the "Executive").

                                    Recitals

     WHEREAS, Executive and the Company's predecessor are parties to that
certain Employment Agreement dated February 26, 1999 (the "Prior Agreement"):

     WHEREAS, on the date of this Agreement, the Company will effect a corporate
reorganization (the "Reorganization") pursuant to which the Company will be
recapitalized and combined with LISN, Holdings, Inc., an Ohio corporation;

     WHEREAS, in connection with the Reorganization, the Parties desire to
terminate the Prior Agreement and replace and supercede the Prior Agreement with
this Agreement; and

     WHEREAS, in connection with the Reorganization, the Company, through its
Board of Directors, desires to retain the services of Executive, and Executive
desires to be retained by the Company, on the terms and conditions set forth in
this Agreement.

                                    Agreement

     For and in consideration of the foregoing and of the mutual covenants of
the parties herein contained, and for other good and valuable consideration, the

<PAGE>   2



     3.   DUTIES. Executive shall serve as and have the title of Vice President
of the Company. The Executive's principal place of employment shall be in West
Palm Beach, Florida. Executive agrees to devote his full business time, energy,
skills and best efforts to such employment while so employed. Nothing in this
Agreement shall preclude Executive from engaging, so long as, in the reasonable
determination of the Board of Directors, such activities do not interfere with
his duties and responsibilities hereunder, in charitable and community affairs,
from managing any passive investment made by him or from serving, subject to the
prior approval of the Board of Directors, as a member of the board of directors
or as a trustee of any other corporation, association or entity.

     4.   COMPENSATION.

     (a)  Base Compensation. The Company shall pay Executive, and Executive
agrees to accept, base compensation at the rate of $230,000 per year, payable in
equal installments no less frequently than monthly, through the Term of this
Agreement ("Base Compensation"). The Base Compensation specified in this Section
4(a) may be increased annually during the Term of this Agreement in the sole
discretion of the Compensation Committee of the Board of Directors.

     5.   FRINGE BENEFITS.

     (a)  Generally. Executive shall be eligible for fringe benefits pursuant to
any insurance, pension or other employee fringe benefit plan approved by the
Board of Directors that now or hereafter may be made available to employees of
the Company and for which Executive will qualify according to his eligibility
under the provisions thereof.

     (b)  Health and Disability Insurance. Executive shall be entitled to
participate in such health and disability insurance plans that the Company
offers to other executive officers of the Company from time to time.

     (c)  Vacation, Holidays and Illness. During the Term of this Agreement,
Executive shall be entitled to such number of days off for vacation, holidays,
illness or any other purposes as currently provided to the Executive in
accordance with the Company's past practice and custom.

     6.   EXPENSES. Except as otherwise agreed to herein, the Executive shall be
reimbursed for all usual expenses incurred on behalf of the Company, in
accordance with Company practices and procedures, provided that:

     (a)  Each such expenditure is of a nature deductible under Section 162 of
the Internal Revenue Code on the Federal income tax return of the Company as a
business expense and not as deductible compensation to Executive; and


                                        2

<PAGE>   3



     (b)  Executive furnishes the Company with adequate documentary evidence
required by the Code or any regulation promulgated thereunder for the
substantiation of such expenditures as a deductible business expense of the
Company and not as deductible compensation to Executive.

Executive agrees that, if at any time, any payment made to Executive by the
Company as a business expense reimbursement shall be disallowed in whole as a
deductible expense to the Company by the appropriate taxing authorities,
Executive shall reimburse the Company to the full extent of such disallowance.

     7.   TERMINATION. The term of Executive's employment under this Agreement
may be terminated prior to expiration of the term provided in Section 2 hereof
only in accordance with the following paragraphs:

     (a)  For Cause. This Agreement may be immediately terminated by the Company
for Cause (as herein defined). For purposes of this Agreement, the term "Cause"
shall mean the termination of the Executive by the Board of Directors of the
Company as a result of the existence or occurrence of one or more of the
following conditions or events:

          (i) a material breach by the Executive of any provision of this
Agreement, or the willful and continued failure of Executive substantially to
perform his duties under his employment with the Company;

          (ii) Executive's willful misconduct in connection with the performance
of his duties as an employee or officer of the Company;

          (iii) performance by the Executive of any act of fraud or material
misrepresentation or a material act of misappropriation which results or is
intended to result in Executive's personal enrichment at the expense of the
Company;

          (iv) conviction of the Executive of any crime which constitutes a
felony offense involving violence (but not involving a motorized vehicle) or
fraud, embezzlement, theft or business activities;

          (v) the entry of a judgment or order enjoining or preventing the
Executive from such activities as are essential for the Executive to perform his
services as required by this Agreement unless such judgment or order is the
subject of an appeal or other proceedings to set it aside or modify it and such
proceedings are timely filed and being pursued with due diligence; or

          (vi) Executive has engaged in willful and deliberate conduct or
activities intended to materially damage the business of the Company, it being
understood that neither conduct or activities pursuant to the Executive's
exercise of his good faith business judgment nor unintentional physical damage
to properties by the Executive shall be a ground for such a determination.

<PAGE>   4



     (b)  Mutual. Executive's employment under this Agreement may be terminated
upon mutual written agreement of the Company and the executive.

     (c)  Death. In the event of the death of Executive, this Agreement shall
terminate immediately.

     (d)  Disability. If, during Executive's employment under this Agreement,
Executive shall become permanently disabled and unable to perform his duties as
required herein ("Disability") for a consecutive period of one hundred eighty
(180) days, then the Company may, upon thirty (30) days written notice to
Executive, terminate Executive's employment under this Agreement.

     8.   DEATH AND DISABILITY. In the event of the termination of Executive's
employment under this Agreement by reason of the Executive's death or
Disability, the Company shall pay Executive (or his heirs and/or personal
representatives), Base Compensation through a date which is one (1) year after
the date of Death or the date of termination for Disability as provided in
Paragraph 7(d), respectively.

     9.   SEVERANCE. In the event of the termination of Executive's employment
under this Agreement for any reason other than Executive's death or Disability,
the Company shall provide the payments and benefits to Executive as indicated
below:

     (a)  With Cause or Voluntary Termination by Executive. If Executive is
terminated for Cause (as defined in Section 7(a) of this Agreement), or if
Executive voluntarily terminates his employment with the Company for any reason
other than because of the relocation of the Company's executive offices outside
the West Palm Beach, Florida area, the Company shall be obligated only to
continue to pay to Executive his Base Compensation, if any, earned up to the
date of termination and shall reimburse the Executive for any expenses to which
the Executive is due reimbursement by the Company under Section 6 hereof. In
addition, Company shall pay vested benefits, if any, owed to Executive under any
plan provided for Executive under Paragraph 5 hereof in accordance with the
terms of such plan as in effect on the date of termination of employment under
this Paragraph 9(a).

     (b)  Without Cause. In the event that the Company shall terminate the
Executive without cause (of if Executive voluntarily terminates his employment
with the Company because of the relocation of the Company's executive offices
outside the West Palm Beach, Florida area), the Company shall be obligated to
continue to pay full compensation and benefits to the Executive through and
including February 28, 2003 as if the Executive had not been so terminated.

     10.  CONFIDENTIAL INFORMATION. Executive recognizes and acknowledges that
he will have access to certain confidential information of the Company and of
corporations with whom the Company does business, and that such information
constitutes valuable, special and unique property of the Company and such other
corporations. For the period of time which is the greater of (i) the fourth
anniversary of the date hereof or (ii) one year after the Executive is no longer


                                        4

<PAGE>   5



employed by the Company ("Confidentiality Period"), Executive agrees not to
disclose or use any confidential information, including without limitation,
information regarding research, developments, product designs or specifications,
manufacturing processes, "know-how," prices, suppliers, customers, costs or any
knowledge or information with respect to confidential or trade secrets of the
Company, it being understood that such confidential information does not include
information that is publicly available unless such information became publicly
available as a result of a breach of this Agreement. Executive acknowledges and
agrees that all notes, records, reports, sketches, plans, unpublished memoranda
or other documents belonging to the Company, but held by Executive, concerning
any information relating to the Company's business, whether confidential or not,
are the property of the Company and will be promptly delivered to it upon
Executive's leaving the employ of the Company. Executive also agrees to execute
such confidentiality agreements that the Board may adopt and may modify from
time to time, as a standard form to be executed by all employees of the Company,
to the extent such standard forms are not materially more restrictive than the
provisions of this Agreement.

     11.  NON-SOLICITATION. At all times during the term of this Agreement, and
thereafter during the Noncompete Period (as defined below), Executive shall not,
directly or indirectly, induce, influence, combine or conspire with, or attempt
to induce, influence, combine or conspire with, any of the officers, employees,
agents, consultants, customers or supplies of the Company to terminate their
employment, or other relationship, with or compete against the Company or any
future subsidiaries, parents or affiliates of the Company in the cable industry
(the "Business").

     12.  NON-COMPETITION. Executive acknowledges that his services and
responsibilities are unique in character and are of particular significance to
the Company, that the Company engages in a competitive business with a national
market and that Executive's continued and exclusive service to the Company under
this Agreement is of a high degree of importance to the Company. Therefore,
subject to the last sentence of this Paragraph 12, for one year after the
Executive is no longer employed by the Company (the "Noncompete Period"),
Executive shall not, directly or indirectly, engage in the Business, or in any
other business which, at the time of Executive's termination, the Company is
actively engaged in, except as an employee or agent of the Company, and shall
not, directly or indirectly, as owner, partner, joint venturer, employee,
broker, agent, corporate officer, principal, licensor, shareholder (unless as
owner of no more than three percent (3%) of the issued and outstanding capital
stock of such entity if such stock is publicly traded) or in any other capacity
whatsoever, engage in or have any connection with any business which is
competitive with the Business, and which operates anywhere in the United States
where the Company is doing or has done business within the prior three (3)
years. In the event Executive is terminated by the Company without Cause prior
to the expiration of the term of this Agreement, the Noncompete Period shall be
modified such that it expires on the date of such involuntary termination.

     13.  RESTRICTIVE COVENANTS.

     (a)  If, in any judicial proceedings, a court shall refuse to enforce any
of the covenants included in Paragraphs 10, 11, or 12 hereof, then such
unenforceable covenant shall be amended to relate to such lesser period or
geographical area as shall be enforceable. In the event the Company should bring
any legal action or other proceeding against Executive for enforcement of this
Agreement, the calculation of the Noncompete Period, if any, shall not include
the period of time commencing with the filing of legal action or other
proceeding to enforce this Agreement through the date of final judgment or final
resolution including all appeals, if any, of such legal action or other
proceeding unless the Company is receiving the practical benefits of Paragraphs
10, 11, and 12 during such time.

     (b)  Executive hereby acknowledges that the restrictions on his activity as
contained in this Agreement are required for the Company's reasonable protection
and is a material inducement to the Company to enter into this Agreement.
Executive hereby agrees that in the event of the violation by him of any of the
provisions of this Agreement, the Company will be entitled to institute and
prosecute proceedings at law or in equity to obtain damages with respect to such
violation or to enforce the specific performance of this Agreement by Executive
or to enjoin Executive from engaging in any activity in violation hereof. The
prevailing party in any litigation brought to enforce the restrictive provisions
contained in this Agreement shall be entitled to reimbursement from the

     16.  REPURCHASE PROVISIONS.

     (a)  Prior to a Public Offering (as that term is defined in that certain
Investor Rights Agreement of the Company dated as of November 8, 1999), in the
event the Executive is either terminated for Cause (as defined in Section 7(a)
of this Agreement) or resigns from employment with the Company ("Repurchase
Termination"), all of the Executive's shares of common stock and preferred stock
and the subordinated promissory notes issued by the Company (which equity
securities and promissory notes Executive received pursuant to the
Reorganization), whether held by Executive or transferred by Executive to one or
more transferees (collectively, the "Executive Securities") shall be subject to
repurchase by the Company as set forth in this Paragraph 16 (the "Repurchase
Option").

     (b)  Following any Repurchase Termination the Company shall have the right,
but not the obligation, to purchase all, but not less than all, of the Executive
Securities for the book value of such securities.

     (c)  The Board of Directors of the Company may elect to exercise the
Repurchase Option by delivering written notice (the "Repurchase Notice") to the
holder or holders of such stock within forty-five (45) days after the date of
the Repurchase Termination. The Repurchase Notice will set forth the number of
shares of the Executive Securities to be acquired from each holder, the
aggregate consideration to be paid for such shares and the time and place for
the closing of the transaction.

     (d)  The closing of the purchase of the Executive Securities pursuant to
the Repurchase Option shall take place on the date designated by the Company in
the Repurchase Notice, which date shall not be more than forty-five (45) days
nor less than two (2) business days after the delivery of the Repurchase Notice.
The Company shall pay for the Executive Securities to be purchased pursuant to
the Repurchase Option by delivery of (i) a check or wire transfer of funds, (ii)
a subordinated note or notes payable prior to the first anniversary of the
closing of such purchase and bearing interest at a rate per annum equal to the
prime rate of interest as announced by Citibank, N.A., or (iii) both (i) and
(ii), in the aggregate amount of the purchase price for such shares; provided
that the Company shall use reasonable efforts to make all such repurchases with
a check or wire transfer of funds unless prohibited by law or by its lenders (in
writing). Any notes issued by the Company pursuant to this Paragraph 16(d) shall
be subject to any restrictive covenants to which the Company is subject at the
time of such purchase. The Company shall be entitled to receive customary
representations and warranties as to title from the sellers regarding such sale
and to require all sellers' signatures be guaranteed. The Company may elect to
assign its right to purchase to the stockholders of the Company (which rights to
purchase shall be distributed pro rata to all


                                        7

<PAGE>   8



stockholders (other than the Executive), based upon the number of votes held by
such stockholders). In the event the Company elects to assign its rights to the
other stockholders of the Company (other than the Executive) such other
stockholders shall have the same right as the Company to purchase stock pursuant
to the Repurchase Notice.

     (e)  Notwithstanding anything to the contrary contained in this Agreement,
all repurchases of the Executive Securities by the Company hereunder shall be
subject to applicable restrictions contained in the Delaware General Corporation
Law and in the Company's and its direct and indirect subsidiaries' debt and
equity financing agreements. If any such restrictions prohibit the repurchase of
the Executive Securities hereunder which the Company is otherwise entitled or
required to make, the Company may make such repurchases as soon as it is
permitted to do so under such restrictions, but in any event within 180 days of
the Repurchase Termination.

     (f)  Notwithstanding anything to the contrary contained in this Agreement,
the Company's right to repurchase the Executive Securities shall terminate upon
the consummation of a Public Offering.

     17.  ENTIRE AGREEMENT; MODIFICATION.

Executive, and the Company and Executive hereby acknowledge and agree that this
Agreement supersedes any prior statements, writings, promises, understandings or
commitments between the parties hereof.

subject matter hereof, or other purported modification hereof, shall be binding

Agreement shall inure to the benefit of and shall be binding upon the successors
and permitted assigns of the parties. Neither party may assign his or its rights
or obligations under this Agreement without the prior written consent of the
other party.

shall in no manner affect the right to enforce the same, and the waiver by any

                              EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made as of the 15th day of
December, 1999 by and between ORIUS CORP., a Florida corporation (the "Company")
and ROBERT AGRES (the "Executive").

                                    Recitals

     WHEREAS, Executive has been employed by the Company as its chief financial
officer;

     WHEREAS, on the date of this Agreement, the Company will effect a corporate
reorganization (the "Reorganization") pursuant to which the Company will be
recapitalized and combined with LISN Holdings, Inc., an Ohio corporation; and

     WHEREAS, in connection with the Reorganization, the Company, through its
Board of Directors, desires to retain the services of Executive, and Executive
desires to be retained by the Company, on the terms and conditions set forth in
this Agreement.

                                    Agreement

     For and in consideration of the foregoing and of the mutual covenants of
the parties herein contained, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as
follows:

     1.   EMPLOYMENT. The Company hereby employs Executive to serve in the
capacities described herein and Executive hereby accepts such employment and
agrees to perform the services described herein upon the terms and conditions
hereinafter set forth.

     2.   TERM. The term of Executive's employment pursuant to this Agreement
shall commence on the effective date hereof and shall terminate at the close of
business on December 15, 2001 (the "Term") subject to earlier termination in
accordance with the other terms and conditions set forth herein.

     3.   DUTIES. Executive shall serve as and have the title of Chief Financial
Officer of the Company. The Executive's principal place of employment shall be
in West Palm Beach, Florida. Executive agrees to devote his full business time,
energy, skills and best efforts to such employment while so employed. Nothing in
this Agreement shall preclude Executive from engaging, so long as, in the
reasonable determination of the Board of Directors, such activities do not
interfere with his duties and responsibilities hereunder, in charitable and
community affairs, from managing any passive investment made by him or from
serving, subject to the prior approval of the Board of



<PAGE>   2



Directors, as a member of the board of directors or as a trustee of any other
corporation, association or entity.

     4.   COMPENSATION.

     (a)  Base Compensation. The Company shall pay Executive, and Executive
agrees to accept, base compensation at the rate of $195,000 per year, payable in
equal installments no less frequently than monthly, through the Term of this
Agreement ("Base Compensation"). The Base Compensation specified in this Section
4(a) may be increased annually during the Term of this Agreement in the sole
discretion of the Compensation Committee of the Board of Directors.

     5.   FRINGE BENEFITS.

     (a)  Generally. Executive shall be eligible for fringe benefits pursuant to
any insurance, pension or other employee fringe benefit plan approved by the
Board of Directors that now or hereafter may be made available to employees of
the Company and for which Executive will qualify according to his eligibility
under the provisions thereof.

     (b)  Health and Disability Insurance. Executive shall be entitled to
participate in such health and disability insurance plans that the Company
offers to other executive officers of the Company from time to time.

     (c)  Vacation, Holidays and Illness. During the Term of this Agreement,
Executive shall be entitled to such number of days off for vacation, holidays,
illness or any other purposes as currently provided to the Executive in
accordance with the Company's past practice and custom.

     6.   EXPENSES. Except as otherwise agreed to herein, the Executive shall be
reimbursed for all usual expenses incurred on behalf of the Company, in
accordance with Company practices and procedures, provided that:

     (a)  Each such expenditure is of a nature deductible under Section 162 of
the Internal Revenue Code on the Federal income tax return of the Company as a
business expense and not as deductible compensation to Executive; and

     (b)  Executive furnishes the Company with adequate documentary evidence
required by the Code or any regulation promulgated thereunder for the
substantiation of such expenditures as a deductible business expense of the
Company and not as deductible compensation to Executive.

Executive agrees that, if at any time, any payment made to Executive by the
Company as a business expense reimbursement shall be disallowed in whole as a
deductible expense to the Company by the appropriate taxing authorities,
Executive shall reimburse the Company to the full extent of such disallowance.

     7.   TERMINATION. The term of Executive's employment under this Agreement
may be terminated prior to expiration of the term provided in Section 2 hereof
only in accordance with the following paragraphs:

     (a)  For Cause. This Agreement may be immediately terminated by the Company
for Cause (as herein defined). For purposes of this Agreement, the term "Cause"
shall mean the termination of the Executive by the Board of Directors of the
Company as a result of the existence or occurrence of one or more of the
following conditions or events:

          (i) a material breach by the Executive of any provision of this
Agreement, or the willful and continued failure of Executive substantially to
perform his duties under his employment with the Company;

          (ii) Executive's willful misconduct in connection with the performance
of his duties as an employee or officer of the Company;

          (iii) performance by the Executive of any act of fraud or material
misrepresentation or a material act of misappropriation which results or is
intended to result in Executive's personal enrichment at the expense of the
Company;

          (iv) conviction of the Executive of any crime which constitutes a
felony offense involving violence (but not involving a motorized vehicle) or
fraud, embezzlement, theft or business activities;

          (v) the entry of a judgment or order enjoining or preventing the
Executive from such activities as are essential for the Executive to perform his
services as required by this Agreement unless such judgment or order is the
subject of an appeal or other proceedings to set it aside or modify it and such
proceedings are timely filed and being pursued with due diligence; or

          (vi) Executive has engaged in willful and deliberate conduct or
activities intended to materially damage the business of the Company, it being
understood that neither conduct or activities pursuant to the Executive's
exercise of his good faith business judgment nor unintentional physical damage
to properties by the Executive shall be a ground for such a determination.

     (b)  Mutual. Executive's employment under this Agreement may be terminated
upon mutual written agreement of the Company and the executive.

     (c)  Death. In the event of the death of Executive, this Agreement shall
terminate immediately.

Executive shall become permanently disabled and unable to perform his duties as
required herein ("Disability") for



                                        3

<PAGE>   4



a consecutive period of one hundred eighty (180) days, then the Company may,
upon thirty (30) days written notice to Executive, terminate Executive's
employment under this Agreement.

     8.   DEATH AND DISABILITY. In the event of the termination of Executive's
employment under this Agreement by reason of the Executive's death or
Disability, the Company shall pay Executive (or his heirs and/or personal
representatives), Base Compensation through a date which is one (1) year after
the date of Death or the date of termination for Disability as provided in
Paragraph 7(d), respectively.

     9.   SEVERANCE. In the event of the termination of Executive's employment
under this Agreement for any reason other than Executive's death or Disability,
the Company shall provide the payments and benefits to Executive as indicated
below:

     (a)  With Cause or Voluntary Termination by Executive. If Executive is
terminated for Cause (as defined in Section 7(a) of this Agreement), or if
Executive voluntarily terminates his employment with the Company for any reason
other than because of the relocation of the Company's executive offices outside
the West Palm Beach, Florida area, the Company shall be obligated only to
continue to pay to Executive his Base Compensation, if any, earned up to the
date of termination and shall reimburse the Executive for any expenses to which
the Executive is due reimbursement by the Company under Section 6 hereof. In
addition, Company shall pay vested benefits, if any, owed to Executive under any
plan provided for Executive under Paragraph 5 hereof in accordance with the
terms of such plan as in effect on the date of termination of employment under
this Paragraph 9(a).

     (b)  Without Cause. In the event that the Company shall terminate the
Executive without cause (or if Executive voluntarily terminates his employment
with the Company because of the relocation of the Company's executive offices
outside the West Palm Beach, Florida area), the Company shall be obligated to
continue to pay full compensation and benefits to the Executive through and
including December 15, 2001 as if the Executive had not been so terminated.

     10.  CONFIDENTIAL INFORMATION. Executive recognizes and acknowledges that
he will have access to certain confidential information of the Company and of
corporations with whom the Company does business, and that such information
constitutes valuable, special and unique property of the Company and such other
corporations. For the period of time which is the greater of (i) the third
anniversary of the date hereof or (ii) one year after the Executive is no longer
employed by the Company ("Confidentiality Period"), Executive agrees not to
disclose or use any confidential information, including without limitation,
information regarding research, developments, product designs or specifications,
manufacturing processes, "know-how," prices, suppliers, customers, costs or any
knowledge or information with respect to confidential or trade secrets of the
Company, it being understood that such confidential information does not include
information that is publicly available unless such information became publicly
available as a result of a breach of this Agreement. Executive acknowledges and
agrees that all notes, records, reports, sketches, plans, unpublished memoranda
or other documents belonging to the Company, but held


                                        4

<PAGE>   5



by Executive, concerning any information relating to the Company's business,
whether confidential or not, are the property of the Company and will be
promptly delivered to it upon Executive's leaving the employ of the Company.
Executive also agrees to execute such confidentiality agreements that the Board
may adopt and may modify from time to time, as a standard form to be executed by
all employees of the Company, to the extent such standard forms are not
materially more restrictive than the provisions of this Agreement.

     11.  NON-SOLICITATION. At all times during the term of this Agreement, and
thereafter during the Noncompete Period (as defined below), Executive shall not,
directly or indirectly, induce, influence, combine or conspire with, or attempt
to induce, influence, combine or conspire with, any of the officers, employees,
agents, consultants, customers or supplies of the Company to terminate their
employment, or other relationship, with or compete against the Company or any
future subsidiaries, parents or affiliates of the Company in the cable industry
(the "Business").

     12.  NON-COMPETITION. Executive acknowledges that his services and
responsibilities are unique in character and are of particular significance to
the Company, that the Company engages in a competitive business with a national
market and that Executive's continued and exclusive service to the Company under
this Agreement is of a high degree of importance to the Company. Therefore,
subject to the last sentence of this Paragraph 12, for one year after the
Executive is no longer employed by the Company (the "Noncompete Period"),
Executive shall not, directly or indirectly, engage in the Business, or in any
other business which, at the time of Executive's termination, the Company is
actively engaged in, except as an employee or agent of the Company, and shall
not, directly or indirectly, as owner, partner, joint venturer, employee,
broker, agent, corporate officer, principal, licensor, shareholder (unless as
owner of no more than three percent (3%) of the issued and outstanding capital
stock of such entity if such stock is publicly traded) or in any other capacity
whatsoever, engage in or have any connection with any business which is
competitive with the Business, and which operates anywhere in the United States
where the Company is doing or has done business within the prior three (3)
years. In the event Executive is terminated by the Company without Cause prior
to the expiration of the term of this Agreement, the Noncompete Period shall be
modified such that it expires on the date of such involuntary termination.

     13.  RESTRICTIVE COVENANTS.

     (a)  If, in any judicial proceedings, a court shall refuse to enforce any
of the covenants included in Paragraphs 10, 11, or 12 hereof, then such
unenforceable covenant shall be amended to relate to such lesser period or
geographical area as shall be enforceable. In the event the Company should bring
any legal action or other proceeding against Executive for enforcement of this
Agreement, the calculation of the Noncompete Period, if any, shall not include
the period of time commencing with the filing of legal action or other
proceeding to enforce this Agreement through the date of final judgment or final
resolution including all appeals, if any, of such legal action or other
proceeding unless the Company is receiving the practical benefits of Paragraphs
10, 11 and 12 during such time.


                                        5

     (b)  Executive hereby acknowledges that the restrictions on his activity as
contained in this Agreement are required for the Company's reasonable protection
and is a material inducement to the Company to enter into this Agreement.
Executive hereby agrees that in the event of the violation by him of any of the
provisions of this Agreement, the Company will be entitled to institute and
prosecute proceedings at law or in equity to obtain damages with respect to such
violation or to enforce the specific performance of this Agreement by Executive
or to enjoin Executive from engaging in any activity in violation hereof. The
prevailing party in any litigation brought to enforce the restrictive provisions
contained in this Agreement shall be entitled to reimbursement from the
nonprevailing party for reasonable attorneys' fees and expenses incurred in
connection with such litigation.

     (c)  Notwithstanding anything to the contrary contained herein, in the
event that Executive engages in any material conduct prohibited by Paragraphs
10, 11, or 12 hereof for any reason whatsoever, Executive shall not receive any
of the severance benefits he otherwise would be entitled to receive pursuant to
Paragraph 9 hereof.

     14.  REMEDIES. The Executive acknowledges that the Company would be
irreparably injured by a violation of Paragraphs 10, 11 or 12 and agrees that
the Company shall be entitled to an injunction restraining the Executive from
any actual or threatened breach of Paragraphs 10, 11 or 12 or any other
appropriate remedy, without bond or other security being required. The Executive
understands and acknowledges that his failure to provide services to the Company
in accordance with the terms of this Agreement will result in financial injury
to the Company, and the Company will be entitled to damages for any such failure
arising from reasons entirely or partly within Executive's control.

     15.  NOTICES. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and if sent by registered mail to

                                                                [EXECUTION COPY]


                           SENIOR MANAGEMENT AGREEMENT


                  THIS SENIOR MANAGEMENT AGREEMENT (the "Agreement") is made as
of November 8, 1999, between Orius Corp., a Florida corporation (the "Company"),
and William J. Mercurio ("Executive").

                  WHEREAS, the Company and Executive have entered into an
employment agreement, dated as of February 26, 1999 (the "Prior Agreement");

                  WHEREAS, the Company has entered into an Agreement and Plan of
Reorganization, dated as of the date of this Agreement, by and among the
Company, LISN Holdings, Inc. ("LISN"), Orius Merger Sub and certain stockholders
of the Company and of LISN named herein (the "Reorganization Agreement"); and

                  WHEREAS, subject to and effective upon the closing of the
transactions contemplated by the Reorganization Agreement and related agreements
(the "Closing"), the Company and Executive desire to enter into this Agreement
and to replace and supercede the Prior Agreement with this Agreement.

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

                  1.  Employment. Subject to and effective upon the Closing, the
Company shall employ Executive, and Executive hereby accepts employment with the
Company, upon the terms and conditions set forth in this Agreement for the
period beginning on the date hereof and ending as provided in Paragraph 6 hereof
(the "Employment Period"). Effective upon the Closing, the Prior Agreement shall
be superceded by this Agreement and shall be of no further force or effect.

                  2.  Position and Duties.

                  (a) During the Employment Period, Executive shall serve as the
Company's President, Chief Executive Officer and Chairman of the board of
directors (the "Board") and shall have the normal duties, responsibilities and
authority of the President, Chief Executive Officer and Chairman of the Board
(including general and active charge of the business and affairs of the Company
and day-to-day operations of the Company and its Subsidiaries), and shall report
to and take direction from the Board.

                  (b) During the Employment Period, Executive shall report to
the Board and shall devote his best efforts and his full business time and
attention (except for permitted vacation periods and reasonable periods of
illness or other incapacity) to the business and affairs of the Company and



<PAGE>   2


its Subsidiaries. Executive shall perform his duties and responsibilities to the
Company and its Subsidiaries hereunder to the best of his abilities in a
diligent, trustworthy, businesslike and efficient manner. This Paragraph 2(b)
shall not preclude Executive, outside normal business hours, from engaging in
appropriate civic, charitable and like activities and from managing his personal
investment portfolio and, subject to Board approval, engaging in other business
ventures unrelated to the business of the Company. Executive shall perform his
duties in the West Palm Beach, Florida area unless he otherwise consents in
writing, and any requirement by the Company to relocate the Company's executive
offices outside the West Palm Beach, Florida area shall entitle Executive, at
his sole option and upon not less than thirty (30) days notice to the Company,
to terminate the Employment Period for Good Reason pursuant to Paragraph 6(b),
whereupon he shall be entitled to receive the same compensation as if the
Company had terminated the Employment Period without Cause.

                  (c) For purposes of this Agreement, "Subsidiaries" shall mean
any corporation or other entity of which the securities or other ownership
interests having the voting power to elect a majority of the board of directors
or other governing body are, at the time of determination, owned by the Company,
directly or through one of more Subsidiaries.

                  3.  Compensation and Benefits.

                  (a) During the Employment Period, Executive's base salary
shall be $470,000 per annum or such increased rate as the Board may designate
from time to time (the "Base Salary"), which salary shall be reviewed at least
annually and be payable in bi-weekly installments in accordance with the
Company's general payroll practices, provided that the Base Salary shall be
adjusted as of each March 1, during the term of this Agreement, beginning March
1, 2000, to reflect the increase, if any, that occurred in the Revised Consumer
Price Index, U.S. City Average (1984 = 100) published by the Bureau of Labor
Statistics of the United States Department of Labor (the "Price Index") (or, if
publication of such Price Index is terminated, any substantially equivalent
successor thereto). Annual adjustments shall be made by determining the
percentage increase in the Price Index over the previous twelve-month period
ending December 31. This percentage shall be applied to the then-existing Base
Salary to determine the dollar amount of the annual Base Salary increase;
provided, however, that if the percentage increase in the Price Index for any
twelve-month period during the Employment Period is less than five percent (5%),
the annual Base Salary shall be increased a minimum of five percent (5%) for
such twelve-month period. Notwithstanding the foregoing, the Board of Directors
may, in its sole discretion, during the term of this Agreement, increase
Executive's Base Salary in an amount greater than his Base Salary would
otherwise be adjusted hereunder. In addition, during the Employment Period,
Executive shall be entitled to participate in all of the Company's employee
benefit programs for which senior executive employees of the Company and its
Subsidiaries are generally eligible. In particular, Section 4 describes that
certain purchase and sale of Executive Shares (as defined below) which shall be
made available to Executive.

                  (b) In addition to the Base Salary, the Board shall award a
bonus ("Bonus") to Executive in an amount not to exceed the Executive's Base
Salary following the end of each fiscal year during the Employment Period based
upon the Company's EBITDA performance for each fiscal year, as follows:

<TABLE>
<CAPTION>

              EBITDA PERFORMANCE                               BONUS
- -------------------------------------------------        -----------------------
<S>                                                    <C>
Less than: prior fiscal year's EBITDA times 1.125        None

Prior fiscal year's EBITDA times 1.125                   50% of Base Salary*

Plan EBITDA                                              75% of Base Salary**

Equal to or greater than Plan EBITDA times 1.10          100% of Base Salary
</TABLE>

*        If the Company achieves EBITDA greater than the EBITDA of the Company
         for the prior fiscal year times 1.125 but less than Plan EBITDA, then
         Executive shall receive a pro rata portion of the difference between a
         Bonus equal to 50% of Base Salary and a Bonus equal to 75% of Base
         Salary.

**       If the Company achieves EBITDA greater than Plan EBITDA but less than
         an amount equal to Plan EBITDA times 1.10, then Executive shall receive
         a pro rata portion of the difference between a Bonus equal to 75% of
         Base Salary and a Bonus equal to 100% of Base Salary.

Payments under this Paragraph 3(b) shall be made within 14 days after the
receipt of the Company's audited annual financial statements from the Company's
accountants for the applicable year. For purposes of this Agreement, "EBITDA"
with respect to the Company and its Subsidiaries shall mean for any period (A)
net income for such period (before determination of such bonus), plus (B)
interest expense for such period, plus (C) depreciation and amortization expense
for such period, plus (D) tax expense in respect of the income taken into
account in the foregoing clause (A), plus (or minus) (E) extraordinary losses
(or gains) incurred in such period; provided that EBITDA for any fiscal year
shall not take into account any of the foregoing items attributable to
businesses acquired by the Company or its Subsidiaries during such fiscal year
(whether by purchase of assets or stock, merger, consolidation or similar
transaction), but such EBITDA shall be taken into account in determining the
Plan EBITDA and Executive's achievement of Bonus for subsequent fiscal years.
For purposes of this Agreement, "Plan EBITDA" means the EBITDA target mutually
agreed to by the Board and Executive prior to the start of any fiscal year
during the Employment Period. For the fiscal year commencing January 1, 2000 and
ending December 31, 2000, the Executive and Company agree that the Plan EBITDA
is $112,100,000.

                  (c) In addition to the compensation and benefits described
elsewhere in this Agreement, Executive may, at the sole discretion of the Board
(or any committee thereof), be entitled to receive such additional bonus or
bonuses in such amounts as may be determined by the Board (or any committee
thereof) in its sole discretion.

                  (d)   In addition to the Base Salary, reimbursement of
expenses and any bonuses payable to Executive pursuant to this Paragraph,
Executive shall be entitled to the following benefits during the Employment
Period, unless otherwise modified by the Board (provided that any such
modification does not materially alter Executive's compensation and benefits
package taken as a whole):

                  (i)   hospitalization insurance, medical insurance and
         disability insurance of such coverage as reasonably determined by the
         Board (but in no event less than the coverage provided to other
         management employees of the Company); provided that all health
         insurance and other benefit plans that Executive participated in under
         this Paragraph 3 shall continue at the Company's expense for the
         benefit of his dependents who were covered under such plans for a
         period of one year after Executive's death; and provided further and
         Executive shall be entitled to continue such health insurance and other
         benefit plans at his expense following termination of his employment
         for any reason other than for Cause (as defined) below until Executive
         becomes eligible for Medicare.

                  (ii)  disability and life insurance in a principal amount not
         less than $1,000,000;

                  (iii) a minimum of five weeks' paid vacation during each
         twelve-month period of this Agreement with full salary and benefits,
         provided that Executive shall not take more than three (3) weeks
         consecutive of vacation, and provided further that Executive shall be
         entitled to carry forward up to two (2) unused vacation weeks from one
         twelve-month period to the next;

                  (iv)  reimbursement for all reasonable expenses incurred by
         Executive in the course of performing his duties and responsibilities
         under this Agreement which are consistent with the Company's policies
         in effect from time to time with respect to travel, entertainment and
         other business expenses, including, without limitation, reimbursement
         of Executive for membership dues in business and professional
         organizations and clubs on a basis reasonably consistent with that in
         effect between Executive and the Company before the date of this
         Agreement, subject in each case to the Company's requirements with
         respect to reporting and documentation of such expenses;

                  (v)   reimbursement (up to a maximum of $10,000 per year) for
         personal legal expenses incurred by Executive, subject to the Company's
         requirements with respect to reporting and documentation of such
         expenses;

                  (vi)  reimbursement (up to a maximum of $3,000 per year) for

<PAGE>   5



                  (vii)  reimbursement of reasonable moving and relocation
         expenses if Executive is required to relocate by the Board and
         Executive consents to such relocation, subject to the Company's
         requirements with respect to reporting and documentation of such
         expenses; and

                  (viii) an annual automobile allowance in the amount of $9,000,
         which allowance (a) may be applied by the Company toward the leasing of
         an automobile by the Company for Executive or (b) may be given directly
         to Executive to reimburse Executive for (x) the purchase or leasing of
         an automobile as the Company and Executive may agree and (y)
         reimbursement of Executive for his out-of-pocket expenses of operating
         an automobile (including fuel costs).

                  (e)    All amounts payable to Executive as compensation
hereunder shall be subject to customary withholding by the Company.

                  4.     Purchase and Sale of Executive Shares.

                  (a)    As soon as practicable after the adjustments
contemplated by Section 1E of the Reorganization Agreement, Executive will
purchase from the Company, and the Company will sell to Executive a number of
Common Shares (equal to .75% of the number of issued and outstanding Common
Shares of the Company as of the Closing) at a price per Common Share equal to
the Orius Common Value Per Share, as finally determined pursuant to Section 1E
of the Reorganization Agreement. The Company will deliver to Executive the
certificates representing such Executive Shares, and Executive will deliver to
the Company a limited recourse promissory note in form and substance to be
reasonably agreed to by the parties, in the aggregate amount of the purchase
price of the Common Shares purchased pursuant to this Paragraph (the "Note").
Upon the purchase of the Common Shares contemplated by this Paragraph 4,
Executive shall execute and deliver to the Company a pledge agreement with
respect to such Common Shares in a form and substance reasonably satisfactory to
the Executive and the Company.

                  (b)    Within 30 days after Executive purchases any Executive
Shares from the Company, Executive will make an effective election with the
Internal Revenue Service under Section 83(b) of the Internal Revenue Code, as
amended, and the regulations promulgated thereunder in the form of Exhibit A
attached hereto.

                  (c)    In connection with the purchase and sale of the
Executive Shares hereunder, Executive represents and warrants to the Company
that:

                  (i)    The Executive Shares to be acquired by Executive
         pursuant to this Agreement will be acquired for Executive's own account
         and not with a view to, or intention of, distribution thereof in
         violation of the Securities Act, or any applicable state securities
         laws, and the Executive Shares will not be disposed of in contravention
         of the Securities Act or any applicable state securities laws.

                  (ii)  Executive is an executive officer of the Company, is
         sophisticated in financial matters and is able to evaluate the risks
         and benefits of the investment in the Executive Shares.

                  (iii) Executive is able to bear the economic risk of his
         investment in the Executive Shares for an indefinite period of time and
         Executive understands and acknowledges that because the Executive
         Shares have not been registered under the Securities Act they cannot be
         sold unless they are subsequently registered under the Securities Act
         or an exemption from such registration is available.

                  (iv)  Executive has had an opportunity to ask questions and
         receive answers concerning the terms and conditions of the offering of
         Executive Shares and has had full access to such other information
         concerning the Company as he has requested.

                  (v)   This Agreement and each of the other agreements
         contemplated hereby constitutes the legal, valid and binding obligation
         of Executive, enforceable in accordance with its terms, and the
         execution, delivery and performance of this Agreement and such other
         agreements by Executive does not and will not conflict with, violate or
         cause a breach of any agreement, contract or instrument to which
         Executive is a party or any judgment, order or decree to which
         Executive is subject, including, without limitation, those agreements
         referred to on Exhibit C attached hereto.

                  (vi)  Except as disclosed on Exhibit C hereto, executive is
         not a party to or bound by any other employment agreement, noncompete
         agreement or confidentiality agreement.

                  (vii) Executive is and will be at the Effective Time a
         resident of the State of Florida.

                  (d)   As an inducement to the Company to issue the Executive
Shares to Executive, and as a condition thereto, Executive acknowledges and
agrees that the issuance of the Executive Shares to Executive shall not entitle
Executive to remain in the employment of the Company or affect the right of the
Company to terminate Executive's employment at any time for any reason.

                  (e)   Vesting of Executive Shares.

                  (i)   Time Vesting Shares. Except as otherwise provided in
         (e)(iii) below, fifty percent (50%) of the Executive Shares (the "Time
         Vesting Shares") will become vested in accordance with the following
         schedule, if and only if as of each such date Executive is still
         employed by the Company:

         Fourth Anniversary of the Closing                    100%
</TABLE>

                  (ii)  Performance-Vesting Shares. Except as otherwise provided
         in e(iii) below, fifty percent (50%) of the Executive Shares shall vest
         on the fifth anniversary of the Closing so long as the Executive has
         remained continuously employed by the Company or its Subsidiaries as of
         such date (the "Performance-Vesting Shares"), provided that vesting
         will accelerate with respect to twenty-five percent of Executive's
         Performance-Vesting Shares on each of the vesting dates set forth in
         e(i) above if the Company has achieved the performance target set by
         the Board of Directors for the then most recently completed fiscal year
         of the Company (it being agreed that the Executive's performance target
         for the fiscal year ending December 31, 2000 is the Company's
         achievement of EBITDA in the amount of $112,100,000). Notwithstanding
         the foregoing, all of the Executive's Performance-Vesting Shares which
         have not yet become vested shall vest on the fifth anniversary of the
         Closing.

                  (iii) All Executive Shares which have not become vested shall
         become vested immediately (i) upon the sale by Willis Stein & Partners
         II, L.P. and Willis Stein & Partners Dutch, L.P. (together, the
         "Investor") of one half or more of the Common Shares held as of the
         Closing by the Investor (ii) if, prior to an initial public offering of
         the Company's Common Shares, a Person or group of Persons (other than
         any Person or group of Persons who are stockholders of the Company
         immediately after the consummation of the transactions contemplated by
         the Reorganization Agreement) has acquired the number of shares
         necessary to elect a majority of the Company's Board of Directors, or
         (iii) a Change-in-Control. Executive Shares which have become vested
         are referred to herein as "Vested Shares," and all other Executive
         Shares are referred to herein as "Unvested Shares."

                  (f)   Repurchase Option.

                  (i)   In the event Executive ceases to be employed by the
         Company for any reason (the "Termination") all of the Unvested Shares
         (whether held by Executive or one or more of Executive's transferees),
         will be subject to repurchase, in each case by the Company pursuant to
         the terms and conditions set forth in this Section 4 (the "Repurchase
         Option").

                  (ii)  In the event of a Termination, the purchase price for
         each Unvested Share will be Executive's Original Cost for such
         Executive Share.

                  (iii) The Company or its designee may elect to purchase all or
         any portion of the Unvested Shares by delivering written notice (the
         "Repurchase Notice") to the Executive within 180 days after the
         Termination. The Repurchase Notice will set forth the number of
         Unvested Shares to be acquired from the Executive, the aggregate
         consideration to be paid for such Unvested Shares and the time and
         place for the closing of the transaction.

                  (iv)  The closing of the purchase of the Executive Shares
         pursuant to the Repurchase Option shall take place on the date
         designated by the Company in the Repurchase Notice, which date shall
         not be more than five days after the delivery of the later of either
         such notice to be delivered. The Company will pay for the Executive
         Shares to be purchased by it pursuant to the Repurchase Option by first
         offsetting amounts outstanding under any bona fide debts owed by
         Executive to the Company or its Subsidiaries; upon full repayment of
         such bona fide debts, the Company will make payment by a check or wire
         transfer of funds in the aggregate amount of the remaining purchase
         price for such Executive Shares. The Company and the Investor will be
         entitled to receive reasonable and customary representations and
         warranties from the sellers regarding such sale and to require all
         sellers' signatures be guaranteed.

                  (v)   Notwithstanding anything to the contrary contained in
         this Agreement, all repurchases of Executive Shares by the Company
         shall be subject to applicable restrictions contained in the Delaware
         General Corporation Law, and in the Company's Investor Rights
         Agreement. If any such restrictions prohibit the repurchase of
         Executive Shares hereunder which the Company is otherwise entitled or
         required to make, the Company may make such repurchases as soon as it
         is permitted to do so under such restrictions; provided that if, and to
         the extent, the Company has not completed such repurchase within one
         year after the date of a Termination, the Company's right to repurchase
         Executive Shares pursuant to the Repurchase Option hereunder shall
         expire.

                  (vi)  The Vested Shares shall not be subject to the Repurchase
         Option hereunder, provided that if within the 60 days immediately
         following Executive's termination hereunder the Executive fails to pay
         in full all amounts owing under the Note, the Vested Shares shall be
         subject to the terms and conditions of the Repurchase Option.

                  (g)   Restrictions on Transfer of Executive Shares.

                  (i)   Transfer of Vested Shares. Executive shall not transfer
         any Vested Share except in accordance with the Investor Rights
         Agreement with respect to Executive's other Shareholder Shares (as
         defined in the Investor Rights Agreement).

                  (ii)  Transfer of Unvested Shares. Executive shall not
         Transfer any Unvested Shares under any circumstances.

                  (h)   Termination of Restrictions. The restrictions on the
Transfer of Executive Shares set forth in this Section 4 will continue with
respect to each Executive Share until the date on which such Executive Share has
been transferred in a transaction permitted by the Investor Rights Agreement.

                  (i)   Additional Restrictions on Transfer of Executive Shares.

                             which he is terminated (such fiscal year, the "Year
                             of Termination") (it being agreed and understood
                             that "pro rata portion" shall be equal to the
                             product of (i) a fraction, the numerator of which
                             is the number of full weeks during which Executive
                             was employed by the Company during the Year of
                             Termination prior to such termination, and the
                             denominator of which is fifty-two and (ii) the
                             amount of Bonus that Executive would have received
                             in accordance with Paragraph 3(b) above had
                             Executive been employed for the entire Year of
                             Termination, and it being further agreed and
                             understood that the pro rata portion of the Bonus
                             as determined in accordance with this Paragraph
                             6(b)(1)(y) (if any) shall be paid at the time such
                             Bonus would have been paid had Executive continued
                             to be employed by the Company for the entire Year
                             of Termination, as provided in Paragraph 3(b)) (the
                             "Severance Payments"). Notwithstanding anything
                             herein to the contrary, in the

                             event that the Employment Period expires on
                             February 28, 2003 in accordance with the terms
                             hereof, (x) the Company may in its sole discretion
                             elect to (but in no event shall the Company be
                             obligated to) make Severance Payments to Executive
                             for one year following such termination of the
                             Employment Period (the "Optional Severance Period")
                             and, in consideration of such Severance Payments,
                             Executive hereby agrees to be subject to the
                             restrictions set forth in Paragraph 9 below during
                             the Optional Severance Period. Executive shall be
                             entitled to the compensation provided by this
                             Paragraph 6(b) if and only if Executive has
                             executed and delivered to the Company the General
                             Release substantially in form and substance as set
                             forth in Exhibit B (the "General Release") attached
                             hereto and only so long as Executive has not
                             breached the provisions of Paragraphs 7, 8 and 9
                             hereof.

                        (2)  Executive's employment hereunder may be terminated
                             by the Corporation for disability. In such event,
                             Executive shall be paid six months of Base Salary
                             in regular installments (and Executive will not be
                             entitled to the Severance Payments), and Executive
                             shall be entitled to continue participation, at the
                             Company's expense, in the Company's health
                             insurance and other benefit plans that Employee
                             participated in under Paragraph 3 hereof. For
                             purposes of this Agreement, "disability" is defined
                             to mean that, as a result of Executive's incapacity
                             due to physical or mental illness:

                             (i)   Executive shall have been absent from his
                                   duties as an officer of the Company on a
                                   substantially full-time basis for four (4)
                                   consecutive months; and

                             (ii)  Within thirty (30) days after the Company
                                   notifies Executive in writing that it intends
                                   to replace him, Executive shall not have
                                   returned to the performance of his duties as
                                   an officer of the Company on a full-time
                                   basis.

                  (c)   If the Employment Period is terminated by the Company
for Cause, or by Executive without Good Reason or expires and is not renewed
hereunder, Executive shall only be entitled to receive his Base Salary, and any
accrued vacation through the date of termination or expiration.

                  (d)   Except as otherwise expressly provided herein, all of
Executive's rights to salary, bonuses, fringe benefits and other compensation
hereunder which accrue or become payable after the termination or expiration of
the Employment Period shall cease upon such termination or expiration; provided
that following the termination of Executive's employment with the Company


                                      -11-

<PAGE>   12


by the Company without Cause or by Executive for Good Reason, Executive shall
have the health care coverage in the Company's then existing group medical
insurance plan Executive would be entitled to under COBRA for a period required
under applicable law or, if less, the end of the Severance Period, at the
Company's sole cost.

                  (e)   For purposes of this Agreement, "Cause" shall mean (i)
the commission of (A) a crime that (I) is a felony or (II) involves moral
turpitude and has resulted in or is reasonably likely to result in material
economic harm to the Company or (B) any other act or omission with respect to
the Company or any of its Subsidiaries that (I) involves dishonesty, breach of
obligation of loyalty to the Company or fraud and (II) has resulted in or is
reasonably likely to result in material economic harm to the Company; (ii)
chronic drug or alcohol abuse or other repeated misconduct causing the Company
or any of its Subsidiaries material economic harm, (iii) substantial and

satisfaction within 15 days after written notice thereof to Executive.

                  (f)  For purposes of this Agreement, "Good Reason" shall mean
(i) the relocation of the Company's executive offices outside the West Palm
Beach, Florida area, (ii) the Company's material breach of this Agreement or
(iii) without Executive's express written consent the assignment to Executive of
duties materially inconsistent with Employee's positions with the Company as set
forth in this Agreement (including status, offices, titles and reporting
requirements, authority, duties or responsibilities as contemplated by Paragraph
2(a)).

                  7.   Confidential Information. Executive acknowledges that the
information, observations and data (including trade secrets) obtained by him
while employed by the Company and its Subsidiaries concerning the business or
affairs of the Company and its Subsidiaries ("Confidential Information") are the
property of the Company and its Subsidiaries. Therefore, Executive agrees that
he shall not disclose to any unauthorized person or use for his own purposes any
Confidential Information without the prior written consent of the Board, unless
and to the extent that the Confidential Information becomes generally known to
and available for use by the public other than as a result of Executive's acts
or omissions or as requested or required by law or court order (provided that
Executive shall notify the Company promptly of such request or requirement so
that the Company may seek an appropriate protective order). Executive shall
deliver to the Company at the termination or expiration of the Employment
Period, or at any other time the Company may request, all memoranda, notes,
plans, records, reports, computer tapes, printouts and software and other
documents and data (and copies thereof) embodying or relating to the
Confidential Information, Work Product (as defined below) or the business of the
Company and its Subsidiaries which he may then possess or have under his
control.

                  8.   Inventions and Patents. Executive acknowledges that all
inventions, innovations, improvements, developments, methods, designs, analyses,
drawings, reports and all


                                      -12-

<PAGE>   13


similar or related information (whether or not patentable) which relate to the
Company's or any of its Subsidiaries' actual business, research and development
or existing or future products or services and which are conceived, developed or
made by Executive while employed by the Company and its Subsidiaries ("Work
Product") belong to the Company and its Subsidiaries. Executive shall promptly
disclose such Work Product to the Board and, at the Company's expense, perform
all actions reasonably requested by the Board (whether during or after the
Employment Period) to establish and confirm such ownership (including, without
limitation, assignments, consents, powers of attorney and other instruments).

                  9.   Non-Compete, Non-Solicitation.

                  (a)  In further consideration of the compensation to be paid
to Executive hereunder, Executive acknowledges that in the course of his
employment with the Company and its Subsidiaries he has and shall become
familiar with the Company's trade secrets and with other Confidential
Information concerning the Company and its Subsidiaries and that his services
have been and shall be of special, unique and extraordinary value to the Company
and its Subsidiaries. Therefore, Executive agrees that until the later of (i)
such time as the Company ceases to make Severance Payments to Executive in
accordance with the terms and conditions of this Agreement (whether during the
Severance Period or the Optional Severance Period) and (ii) the second
anniversary of the end of the Employment Period if Executive resigns without
Good Reason or is terminated for Cause (the "Noncompete Period"), he shall not
directly or indirectly own any interest in, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
competing with the businesses of the Company or its Subsidiaries, as such
businesses exist or are in process on the date of the termination or expiration
of the Employment Period, within any geographical area in which the Company or
its Subsidiaries engage at any time during the Employment Period in such
businesses. Nothing herein shall prohibit Executive from being a passive owner
of not more than 3% of the outstanding stock of any class of a corporation which
is publicly traded, so long as Executive has no active participation in the
business of such corporation.

                  (b)  During the Noncompete Period, Executive shall not
directly or indirectly through another entity (i) induce or attempt to induce
any employee of the Company or any Subsidiary to leave the employ of the Company
or such Subsidiary, or in any way interfere with the relationship between the
Company or any Subsidiary and any employee thereof, (ii) hire any person who was
a management or supervisory employee of the Company or any Subsidiary at any
time during the Employment Period or (iii) induce or attempt to induce any
customer, supplier, licensee, licensor, franchisee or other business relation of
the Company or any Subsidiary to cease doing business with the Company or such
Subsidiary, or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company or any
Subsidiary (including, without limitation, making any statement which is
intended or reasonably calculated to disparage or discredit the Company or its
Subsidiaries).

                  (c)  If, at the time of enforcement of this Paragraph 9, a
court shall hold that the duration, scope or area restrictions stated herein are
unreasonable under circumstances then existing,


                                      -13-

<PAGE>   14


the parties agree that the maximum duration, scope or area reasonable under such
circumstances shall be substituted for the stated duration, scope or area and
that the court shall be allowed to revise the restrictions contained herein to
cover the maximum period, scope and area permitted by law. Executive
acknowledges that the restrictions contained in this Paragraph 9 are reasonable
and that he has reviewed the provisions of this Agreement with his legal
counsel.

                  (d)  In the event of the breach or a threatened breach by
Executive of any of the provisions of this Paragraph 9, the Company, in addition
and supplementary to other rights and remedies existing in its favor, shall be
entitled to specific performance and/or injunctive or other equitable relief
from a court of competent jurisdiction in order to enforce or prevent any
violations of the provisions hereof (without posting a bond or other security).
In addition, in the event of a breach or violation by Executive of this
Paragraph 9, the Noncompete Period shall be tolled until such breach or
violation has been duly cured.

                                 GENERAL RELEASE


                  I, William J. Mercurio, in consideration of and subject to the
performance by Orius Corp., a Delaware corporation (together with its

of the Company and its direct or indirect owners (collectively, the "Released
Parties") to the extent provided below.

1.       I understand that any payments or benefits paid or granted to me under
         Paragraph 6(b) of the Agreement represent, in part, consideration for
         signing this General Release and are not salary, wages or benefits to
         which I was already entitled. I understand and agree that I will not

         Agreement unless I execute this General Release and do not revoke this
         General Release within the time period permitted hereafter or breach
         this General Release.

2.       Except as provided in Paragraphs 4 and 11 below, I knowingly and
         voluntarily release and forever discharge the Company and the other
         Released Parties from any and all claims, controversies, actions,
         causes of action, cross-claims, counter-claims, demands, debts,
         compensatory damages, liquidated damages, punitive or exemplary

         known or unknown, suspected, or claimed against the Company or any of
         the Released Parties which I, my spouse, or any of my heirs, executors,
         administrators or assigns, may have, which arise out of or are
         connected with my employment with, or my separation from, the Company
         (including, but not limited to, any allegation, claim or violation,
         arising under: Title VII of the Civil Rights Act of 1964, as amended;
         the Civil Rights Act of 1991; the Age Discrimination in Employment Act

         distress, defamation; or any claim for costs, fees, or other expenses,

3.       I represent that I have made no assignment or transfer of any right,
         claim, demand, cause of action, or other matter covered by Paragraph 2
         above.

4.       This General Release does not waive or release any rights or claims
         that I may have (a) under the Age Discrimination in Employment Act of
         1967 which arise after the date I execute this General Release or (b)
         for benefits to which he may be entitled under any employee plan or
         agreement. I acknowledge and agree that my separation from employment
         with the Company in compliance with the terms of the Agreement shall
         not serve as the basis for any claim or action (including, without
         limitation, any claim under the Age Discrimination in Employment Act of
         1967).

5.       In signing this General Release, I acknowledge and intend that it shall
         be effective as a bar to each and every one of the Claims hereinabove
         mentioned or implied. I expressly consent that this General Release
         shall be given full force and effect according to each and all of its
         express terms and provisions, including those relating to unknown and
         unsuspected Claims (notwithstanding any state statute that expressly
         limits the effectiveness of a general release of unknown, unsuspected
         and unanticipated Claims), if any, as well as those relating to any
         other Claims hereinabove mentioned or implied. I acknowledge and agree
         that this waiver is an essential and material term of this General
         Release and that without such waiver the Company would not have agreed
         to the terms of the Agreement. I further agree that in the event I
         should bring a Claim seeking damages against the Company, or in the
         event I should seek to recover against the Company in any Claim brought
         by a governmental agency on my behalf, this General Release shall serve
         as a complete defense to such Claims. I further agree that I am not
         aware of any pending charge or complaint of the type described in
         Paragraph 2 as of the execution of this General Release.

6.       I agree that neither this General Release, nor the furnishing of the
         consideration for this General Release, shall be deemed or construed at
         any time to be an admission by the Company, any Released Party or
         myself of any improper or unlawful conduct.

7.       I agree that I will forfeit all amounts payable by the Company pursuant
         to the Agreement if I challenge the validity of this General Release. I
         also agree that if I violate this General Release by suing the Company
         or the other Released Parties, I will pay all costs and expenses of
         defending against the suit incurred by the Released Parties, including
         reasonable attorneys' fees, and return all payments received by me
         pursuant to the Agreement.

8.       I agree that this General Release is confidential and agree not to
         disclose any information regarding the terms of this General Release,
         except to my immediate family and any tax, legal or other counsel I
         have consulted regarding the meaning or effect hereof or as required by
         law, and I will instruct each of the foregoing not to disclose the same
         to anyone.

9.       Any non-disclosure provision in this General Release does not prohibit
         or restrict me (or my attorney) from responding to any inquiry about
         this General Release or its underlying facts


                                       -5-

         and circumstances by the Securities and Exchange Commission (SEC), the
         National Association of Securities Dealers, Inc. (NASD), any other
         self-regulatory organization or governmental entity.

10.      I agree to reasonably cooperate with the Company in any internal
         investigation or administrative, regulatory, or judicial proceeding. I
         understand and agree that my cooperation may include, but not be
         limited to, making myself available to the Company upon reasonable
         notice for interviews and factual investigations; appearing at the
         Company's request to give testimony without requiring service of a
         subpoena or other legal process; volunteering to the Company pertinent
         information; and turning over to the Company all relevant documents
         which are or may come into my possession all at times and on schedules
         that are reasonably consistent with my other permitted activities and
         commitments. I understand that in the event the Company asks for my
         cooperation in accordance with this provision, the Company will
         reimburse me solely for reasonable travel expenses, including lodging
         and meals, upon my submission of receipts.

11.      Notwithstanding anything in this General Release to the contrary, this
         General Release shall not relinquish, diminish, or in any way affect
         any rights or claims arising out of any breach by the Company or by any
         Released Party of the Agreement.

12.      Whenever possible, each provision of this General Release shall be
         interpreted in, such manner as to be effective and valid under
         applicable law, but if any provision of this General Release is held to
         be invalid, illegal or unenforceable in any respect under any
         applicable law or rule in any jurisdiction, such invalidity, illegality
         or unenforceability shall not affect any other provision or any other
         jurisdiction, but this General Release shall be reformed, construed and
         enforced in such jurisdiction as if such invalid, illegal or
         unenforceable provision had never been contained herein.

                              EMPLOYMENT AGREEMENT
                              --------------------


                  THIS AGREEMENT is made as of May 28, 1999, between LISN, Inc.,
an Ohio corporation (the "Company"), and Donald J. Vanke ("Executive").

                  The execution and delivery of this Agreement by the Company
and Executive are mutual conditions to the recapitalization of the Company and
its affiliates pursuant to a Recapitalization Agreement of even date herewith
between the Company, LISN Holdings, Inc., Arion, Inc., Willis Stein & Partners
II, L.P., Willis Stein & Partners Dutch, L.P., Executive, Donald L. Sanneman,
James S. Hivnor, the Donald J. Vanke Revocable Electing Small Business Trust
(dated December 25, 1998) and the James S. Hivnor Revocable Electing Small
Business Trust (dated December 25, 1998) (the "Recapitalization Agreement").

                  In consideration of the mutual covenants contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

                  1. Employment. The Company shall employ Executive, and
Executive hereby accepts employment with the Company, upon the terms and
conditions set forth in this Agreement for the period beginning on the date
hereof and ending as provided in Paragraph 5 hereof (the "Employment Period").

                  2. Position and Duties.

                  (a) During the Employment Period, Executive shall serve as the
President and Chief Executive Officer of the Company and shall have the normal
duties, responsibilities and authority of the President and Chief Executive
Officer, and shall report to and take direction from the Company's board of
directors (the "Board").

                  (b) During the Employment Period, Executive shall report to
the Board and shall devote his best efforts and his full business time and
attention (except for permitted vacation periods and reasonable periods of
illness or other incapacity) to the business and affairs of the Company and its
Subsidiaries. Executive shall perform his duties and responsibilities to the
Company and its Subsidiaries hereunder to the best of his abilities in a
diligent, trustworthy, businesslike and efficient manner. This Paragraph 2(b)
shall not preclude Executive, outside normal business hours, from engaging in
appropriate civic, charitable and like activities and from managing his personal
investment portfolio and, subject to Board approval, engaging in other business
ventures unrelated to the business of the Company. Executive shall perform his
duties in the Cleveland/Lorain, Ohio area unless he otherwise consents in
writing, and any requirement by the Company to relocate the Company's executive
offices outside the Cleveland/Lorain, Ohio area shall entitle Executive, at his
sole option and upon not less than thirty (30) days notice to the Company, to
terminate the Employment Period for Good Reason pursuant to Paragraph 5(b),
whereupon he shall be entitled to

receive the same compensation as if the Company had terminated the Employment
Period without Cause.

                  (c) For purposes of this Agreement, "Subsidiaries" shall mean
any corporation or other entity of which the securities or other ownership
interests having the voting power to elect a majority of the board of directors
or other governing body are, at the time of determination, owned by the Company,
directly or through one of more Subsidiaries.

                  3. Compensation and Benefits.

                  (a) During the Employment Period, Executive's base salary
shall be $300,000 per annum or such increased rate as the Board may designate
from time to time (the "Base Salary"), which salary shall be reviewed at least
annually and be payable in weekly installments in accordance with the Company's
general payroll practices. In addition, during the Employment Period, Executive
shall be entitled to participate in all of the Company's employee benefit
programs for which senior executive employees of the Company and its
Subsidiaries are generally eligible.

                  (b) In addition to the Base Salary, the Board shall award a
bonus to Executive equal to 100% of Executive's Base Salary following the end of
each fiscal year during the Employment Period based upon: (i) for the fiscal
year ending December 31, 1999, the achievement by the Company of EBITDA of at
least $25,600,000 for the fiscal year ending December 31, 1999 and (ii) for
fiscal years ending after December 31, 1999, the achievement by the Company of
EBITDA targets mutually agreed to by the Board and Executive prior to the start
of such fiscal year. Payments under this Paragraph 3(b) shall be made within 14
days after the receipt of the Company's audited annual financial statements from
the Company's accountants for the applicable year. For purposes of this
Agreement, "EBITDA" with respect to the Company and its Subsidiaries shall mean
for any period (A) net income for such period (before determination of such
bonus), plus (B) interest expense for such period, plus (C) depreciation and
amortization expense for such period, plus (D) tax expense in respect of the
income taken into account in the foregoing clause (A), plus (or minus) (E)
extraordinary losses (or gains) incurred in such period; provided that EBITDA
shall not take into account any of the foregoing items attributable to
businesses acquired by the Company or its Subsidiaries after the date hereof
(whether by purchase of assets or stock, merger, consolidation or similar
transaction).

                  (c) In addition to the compensation and benefits described
elsewhere in this Agreement, Executive may, at the sole discretion of the Board
(or any committee thereof), be entitled to receive such bonus or bonuses in such
amounts as may be determined by the Board (or any committee thereof) in its sole
discretion.

                  (d) In addition to the Base Salary, reimbursement of expenses
and any bonuses payable to Executive pursuant to this Paragraph, Executive shall
be entitled to the following benefits during the Employment Period, unless
otherwise modified by the Board (provided that any such

                                       -2-

<PAGE>   3



modification does not materially alter Executive's compensation and benefits
package taken as a whole):

         disability insurance of such coverage as reasonably determined by the

         Executive's choice, subject to the Company's requirements with respect
         to reporting and documentation of such expenses;

                   (iv) a maximum of six weeks vacation each year with full
         salary and benefits which vacation if not taken in any one year may not
         be carried forward into subsequent years;

                    (v) reimbursement for all reasonable expenses incurred by
         Executive in the course of performing his duties and responsibilities
         under this Agreement which are consistent with the Company's policies
         in effect from time to time with respect to travel, entertainment and
         other business expenses, subject to the Company's requirements with
         respect to reporting and documentation of such expenses;

                   (vi) reimbursement (up to a maximum of $10,000 per year) for

         requirements with respect to reporting and documentation of such
         expenses;

                  (vii) reimbursement (up to a maximum of $3,000 per year) for

         expenses; and

                   (ix) use of an automobile owned or leased by the Company
         comparable to the automobile used by Executive as of the date of this
         Agreement together with payment of all reasonable expenses incurred in
         its operation, subject to the Company's requirements with respect to
         reporting and documentation of such expenses and subject to
         reimbursement by Executive (through payroll deduction) of Company for
         personal use of such vehicle at the rate of $200 per month.

                    (e) All amounts payable to Executive as compensation

his Base Salary payable in regular installments and all bonuses earned under
Paragraph 3(b) (the "Severance Payments") from the date of termination through
the longer of six months from the date of termination and the second anniversary
of this Agreement (the "Severance Period"). Notwithstanding anything herein to
the contrary, Executive shall be entitled to the compensation provided by this
Paragraph 5(b) if and only if Executive has executed and delivered to the
Company the General Release substantially in form and substance as set forth in

                  (c) If the Employment Period is terminated by the Company for

                                       -4-

<PAGE>   5



by the Company without Cause or by Executive for Good Reason, Executive shall
have the health care coverage in the Company's then existing group medical
insurance plan Executive would be entitled to under COBRA for a period required
under applicable law or, if less, the end of the Severance Period, at the
Company's sole cost.

                  (e) For purposes of this Agreement, "Cause" shall mean (i) the
commission of a felony or other crime involving moral turpitude or the

two-thirds vote of the disinterested members of the Board in good faith), (ii)
chronic drug or alcohol abuse or other repeated conduct causing the Company or
any of its Subsidiaries substantial public disgrace or disrepute or economic

within 15 days after written notice thereof to Executive, (iv) gross negligence
or willful misconduct with respect to the Company or any of its Subsidiaries or

                  6. Confidential Information. Executive acknowledges that the
information, observations and data (including trade secrets) obtained by him
while employed by the Company and its Subsidiaries concerning the business or
affairs of the Company and its Subsidiaries ("Confidential Information") are the
property of the Company and its Subsidiaries. Therefore, Executive agrees that
he shall not disclose to any unauthorized person or use for his own purposes any
Confidential Information without the prior written consent of the Board, unless
and to the extent that the Confidential Information becomes generally known to
and available for use by the public other than as a result of Executive's acts
or omissions or as requested or required by law or court order (provided that
Executive shall notify the Company promptly of such request or requirement so
that the Company may seek an appropriate protective order). Executive shall
deliver to the Company at the termination or expiration of the Employment
Period, or at any other time the Company may request, all memoranda, notes,
plans, records, reports, computer tapes, printouts and software and other
documents and data (and copies thereof) embodying or relating to the
Confidential Information, Work Product (as defined below) or the business of the
Company and its Subsidiaries which he may then possess or have under his
control.

                  7. Inventions and Patents. Executive acknowledges that all
inventions, innovations, improvements, developments, methods, designs, analyses,
drawings, reports and all similar or related information (whether or not
patentable) which relate to the Company's or any of its Subsidiaries' actual
business, research and development or existing or future products or services
and which are conceived, developed or made by Executive while employed by the
Company and its Subsidiaries ("Work Product") belong to the Company and its
Subsidiaries. Executive shall

                                       -5-

<PAGE>   6



promptly disclose such Work Product to the Board and, at the Company's expense,
perform all actions reasonably requested by the Board (whether during or after
the Employment Period) to establish and confirm such ownership (including,
without limitation, assignments, consents, powers of attorney and other
instruments).

                  8. Non-Compete, Non-Solicitation.

                  (a) In further consideration of the compensation to be paid to
Executive hereunder, Executive acknowledges that in the course of his employment
with the Company and its Subsidiaries he has and shall become familiar with the
Company's trade secrets and with other Confidential Information concerning the
Company and its Subsidiaries and that his services have been and shall be of
special, unique and extraordinary value to the Company and its Subsidiaries.
Therefore, Executive agrees that, during the Employment Period and for two years
thereafter (the "Noncompete Period"), he shall not directly or indirectly own
any interest in, manage, control, participate in, consult with, render services
for, or in any manner engage in any business competing with the businesses of
the Company or its Subsidiaries, as such businesses exist or are in process on
the date of the termination or expiration of the Employment Period, within any
geographical area in which the Company or its Subsidiaries engage or plan to
engage at any time during the Employment Period in such businesses, so long as
the Company makes the Severance Payments in accordance with Paragraph 5(b).
Nothing herein shall prohibit Executive from being a passive owner of not more
than 2% of the outstanding stock of any class of a corporation which is publicly
traded, so long as Executive has no active participation in the business of such
corporation.

                  (b) During the Noncompete Period, Executive shall not directly
or indirectly through another entity (i) induce or attempt to induce any
employee of the Company or any Subsidiary to leave the employ of the Company or
such Subsidiary, or in any way interfere with the relationship between the
Company or any Subsidiary and any employee thereof, (ii) hire any person who was
an employee of the Company or any Subsidiary at any time during the Employment
Period or (iii) induce or attempt to induce any customer, supplier, licensee,
licensor, franchisee or other business relation of the Company or any Subsidiary
to cease doing business with the Company or such Subsidiary, or in any way
interfere with the relationship between any such customer, supplier, licensee or
business relation and the Company or any Subsidiary (including, without
limitation, making any statement which is intended or reasonably calculated to
disparage or discredit the Company or its Subsidiaries).

                  (c) If, at the time of enforcement of this Paragraph 8, a
court shall hold that the duration, scope or area restrictions stated herein are
unreasonable under circumstances then existing, the parties agree that the
maximum duration, scope or area reasonable under such circumstances shall be
substituted for the stated duration, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum period,
scope and area permitted by law. Executive acknowledges that the restrictions
contained in this Paragraph 8 are reasonable and that he has reviewed the
provisions of this Agreement with his legal counsel.

                  (d) In the event of the breach or a threatened breach by
Executive of any of the provisions of this Paragraph 8, the Company, in addition
and supplementary to other rights and remedies existing in its favor, shall be
entitled to specific performance and/or injunctive or other equitable relief
from a court of competent jurisdiction in order to enforce or prevent any
violations of the provisions hereof (without posting a bond or other security).
In addition, in the event of a breach or violation by Executive of this
Paragraph 8, the Noncompete Period shall be tolled until such breach or
violation has been duly cured.

                  9. Representations. Each of Executive and the Company hereby
represents and warrants to the other that (i) the execution, delivery and
performance of this Agreement by such party do not and shall not conflict with,
breach, violate or cause a default under any contract, agreement, instrument,
order, judgment or decree to which such party is a party or by which he or it is
bound, and (ii) upon the execution and delivery of this Agreement by each of
Executive and the Company, this Agreement shall be the valid and binding
obligation of such party, enforceable in accordance with its terms. Executive
further represents and warrants to the Company that he is not a party to or
bound by any employment agreement, noncompete agreement or confidentiality
agreement with any other person or entity. Executive hereby acknowledges and
represents that he has consulted with independent legal counsel regarding his
rights and obligations under this Agreement and that he fully understands the
terms and conditions contained herein.

                  10. Survival. Paragraphs 6 through 20 shall survive and

expiration or termination of the Employment Period.

WITH, THE LAWS OF THE STATE OF OHIO, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW
OR CONFLICT OF LAW RULES OR PROVISIONS (WHETHER OF THE STATE OF OHIO OR ANY
OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY
JURISDICTION OTHER THAN THE STATE OF OHIO.

                  18. Amendment and Waiver. The provisions of this Agreement may
be amended or waived only with the prior written consent of the Company (as
approved by the Board) and Executive, and no course of conduct or failure or
delay in enforcing the provisions of this Agreement shall affect the validity,
binding effect or enforceability of this Agreement.

                  19. Indemnification. Company hereby agrees to indemnify and
hold Executive harmless to the maximum extent permitted by law as designated in
the Company's Regulations, which provision shall not be amended during the
Employment Period without Executive's prior written consent.

                  20. Arbitration. Except with respect to disputes or claims
under Paragraphs 6, 7 and 8 hereof (for which each party shall bear the cost of
his or its own attorney's fees and expenses), each party hereto agrees that the
arbitration procedure set forth in Exhibit B hereto shall be the sole and
exclusive method for resolving any claim or dispute ("Claim") arising out of or
relating to the rights and obligations acknowledged and agreed to in this
Agreement, whether such Claim arose or the facts on which such Claim is based
occurred prior to or after the effective date of adoption of this Agreement. The
parties agree that the result of any arbitration hereunder shall be final,
conclusive and binding on all of the parties. Nothing in this section shall
prohibit a party hereto from instituting litigation to enforce any Final
Determination (as defined in Exhibit B hereto). Each party hereto hereby
irrevocably submits to the jurisdiction of any United States District Court of
the Northern District of Ohio (Eastern Division), and an Ohio state court of
competent jurisdiction sitting in Lorain County, Ohio, and agrees that such
courts shall be the exclusive forum for the enforcement of any Final
Determination. Each party hereto irrevocably consents to service of process by
registered mail or personal service and waives any objection on the grounds of
personal jurisdiction, venue or inconvenience of the forum. Each party hereto
further agrees that each other party hereto may initiate litigation in any court
of competent jurisdiction to execute any judicial judgment enforcing a Final
Determination.

                                 GENERAL RELEASE


         I, Donald J. Vanke, in consideration of and subject to the performance
by LISN, Inc., an Ohio corporation (together with its subsidiaries, the
"Company"), of its material obligations under the Employment Agreement, dated as
of May 28, 1999 (the "Agreement"), do hereby release and forever discharge as of
the date hereof the Company and all present and former directors, officers,
agents, representatives, employees, successors and assigns of the Company and
its direct or indirect owners (collectively, the "Released Parties") to the
extent provided below.

1.       I understand that any payments or benefits paid or granted to me under
         Paragraph 5(b) of the Agreement represent, in part, consideration for
         signing this General Release and are not salary, wages or benefits to
         which I was already entitled. I understand and agree that I will not
         receive the payments and benefits specified in Paragraph 5(b) of the
         Agreement unless I execute this General Release and do not revoke this
         General Release within the time period permitted hereafter or breach
         this General Release.

2.       Except as provided in Paragraph 4 below, I knowingly and voluntarily
         release and forever discharge the Company and the other Released
         Parties from any and all claims, controversies, actions, causes of
         action, cross-claims, counter-claims, demands, debts, compensatory
         damages, liquidated damages, punitive or exemplary damages, other
         damages, claims for costs and attorneys' fees, or liabilities of any
         nature whatsoever in law and in equity, both past and present (through
         the date of this General Release) and whether known or unknown,
         suspected, or claimed against the Company or any of the Released
         Parties which I, my spouse, or any of my heirs, executors,
         administrators or assigns, may have, which arise out of or are
         connected with my employment with, or my separation from, the Company
         (including, but not limited to, any allegation, claim or violation,
         arising under: Title VII of the Civil Rights Act of 1964, as amended;
         the Civil Rights Act of 1991; the Age Discrimination in Employment Act
         of 1967, as amended (including the Older Workers Benefit Protection
         Act); the Equal Pay Act of 1963, as amended; the Americans with
         Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the
         Civil Rights Act of 1866, as amended; the Worker Adjustment Retraining
         and Notification Act; the Employee Retirement Income Security Act of
         1974; any applicable Executive Order Programs; the Fair Labor Standards
         Act; or their state or local counterparts; or under any other federal,
         state or local civil or human rights law, or under any other local,
         state, or federal law, regulation or ordinance; or under any public
         policy, contract or tort, or under common law; or arising under any
         policies, practices or procedures of the Company; or any claim for
         wrongful discharge, breach of contract, infliction of emotional
         distress, defamation; or any claim for costs, fees, or other expenses,
         including attorneys' fees incurred in these matters) (all of the
         foregoing collectively referred to herein as the "Claims"). ------

3.       I represent that I have made no assignment or transfer of any right,
         claim, demand, cause of action, or other matter covered by Paragraph 2
         above.

4.       I agree that this General Release does not waive or release any rights
         or claims that I may have under the Age Discrimination in Employment
         Act of 1967 which arise after the date I execute this General Release.
         I acknowledge and agree that my separation from employment with the
         Company in compliance with the terms of the Agreement shall not serve
         as the basis for any claim or action (including, without limitation,
         any claim under the Age Discrimination in Employment Act of 1967).

5.       In signing this General Release, I acknowledge and intend that it shall
         be effective as a bar to each and every one of the Claims hereinabove
         mentioned or implied. I expressly consent that this General Release
         shall be given full force and effect according to each and all of its
         express terms and provisions, including those relating to unknown and
         unsuspected Claims (notwithstanding any state statute that expressly
         limits the effectiveness of a general release of unknown, unsuspected
         and unanticipated Claims), if any, as well as those relating to any
         other Claims hereinabove mentioned or implied. I acknowledge and agree
         that this waiver is an essential and material term of this General
         Release and that without such waiver the Company would not have agreed
         to the terms of the Agreement. I further agree that in the event I
         should bring a Claim seeking damages against the Company, or in the
         event I should seek to recover against the Company in any Claim brought
         by a governmental agency on my behalf, this General Release shall serve
         as a complete defense to such Claims. I further agree that I am not
         aware of any pending charge or complaint of the type described in
         Paragraph 2 as of the execution of this General Release.

6.       I agree that neither this General Release, nor the furnishing of the
         consideration for this General Release, shall be deemed or construed at
         any time to be an admission by the Company, any Released Party or
         myself of any improper or unlawful conduct.

7.       I agree that I will forfeit all amounts payable by the Company pursuant
         to the Agreement if I challenge the validity of this General Release. I
         also agree that if I violate this General Release by suing the Company
         or the other Released Parties, I will pay all costs and expenses of
         defending against the suit incurred by the Released Parties, including
         reasonable attorneys' fees, and return all payments received by me
         pursuant to the Agreement.

8.       I agree that this General Release is confidential and agree not to
         disclose any information regarding the terms of this General Release,
         except to my immediate family and any tax, legal or other counsel I
         have consulted regarding the meaning or effect hereof or as required by
         law, and I will instruct each of the foregoing not to disclose the same
         to anyone.

9.       Any non-disclosure provision in this General Release does not prohibit
         or restrict me (or my attorney) from responding to any inquiry about
         this General Release or its underlying facts and circumstances by the
         Securities and Exchange Commission (SEC), the National Association of
         Securities Dealers, Inc. (NASD), any other self-regulatory organization
         or governmental entity.

10.      I agree to reasonably cooperate with the Company in any internal
         investigation or administrative, regulatory, or judicial proceeding. I
         understand and agree that my cooperation may include, but not be
         limited to, making myself available to the Company upon reasonable
         notice for interviews and factual investigations; appearing at the
         Company's request to give testimony without requiring service of a
         subpoena or other legal process; volunteering to the Company pertinent
         information; and turning over to the Company all relevant documents
         which are or may come into my possession all at times and on schedules
         that are reasonably consistent with my other permitted activities and
         commitments. I understand that in the event the Company asks for my
         cooperation in accordance with this provision, the Company will
         reimburse me solely for reasonable travel expenses, including lodging
         and meals, upon my submission of receipts.

11.      Notwithstanding anything in this General Release to the contrary, this
         General Release shall not relinquish, diminish, or in any way affect
         any rights or claims arising out of any breach by the Company or by any
         Released Party of the Agreement.

12.      Whenever possible, each provision of this General Release shall be
         interpreted in, such manner as to be effective and valid under
         applicable law, but if any provision of this General Release is held to
         be invalid, illegal or unenforceable in any respect under any
         applicable law or rule in any jurisdiction, such invalidity, illegality
         or unenforceability shall not affect any other provision or any other
         jurisdiction, but this General Release shall be reformed, construed and
         enforced in such jurisdiction as if such invalid, illegal or
         unenforceable provision had never been contained herein.

BY SIGNING THIS GENERAL RELEASE, I REPRESENT AND AGREE THAT:

(a)      I HAVE READ IT CAREFULLY;

(b)      I UNDERSTAND ALL OF ITS TERMS AND KNOW THAT I AM GIVING UP IMPORTANT

                                                                       EXHIBIT B

                              ARBITRATION PROCEDURE
                              ---------------------

                  1. Notice of Claim. A party asserting a Claim (the "Claimant")
shall deliver written notice to each party against whom the Claim is asserted
(collectively, the "Opposing Party"), with a copy to the persons required to
receive copies of notices under the Agreement (the "Additional Notice Parties"),
specifying the nature of the Claim and requesting a meeting to resolve same. The
Additional Notice Parties shall be given reasonable notice of and invited and
permitted to attend any such meeting. If no resolution is reached within 10
business days after delivery of such notice, the Claimant or the Opposing Party
may, within 45 days after giving such notice, invoke the arbitration procedure
provided herein by delivering to each Opposing Party and the Additional Notice
Parties a Notice of Arbitration, which shall specify the Claim as to which
arbitration is sought, the nature of the Claim, the basis for the Claim, and the
nature and amount of any damages or other compensation or relief sought. Each
party agrees that no punitive damages may be sought or recovered in any
arbitration, judicial proceeding or otherwise. Failure to file a Notice of
Arbitration within 45 days shall constitute a waiver of any right to relief for
the matters asserted in the notice of claim. Any Claim shall be forever barred,
and no relief may be sought therefor, if written notice of such Claim is not
made as provided above within one year of the date such claim accrues.

                  2. Selection of Arbitrator. Within 20 business days of receipt
of the Notice of Arbitration, the Executive and the Board shall meet and attempt
to agree on an arbitrator to hear and decide the Claim. If the Executive and the
Board cannot agree on an arbitrator within ten business days, then they shall
request the American Arbitration Association (the "AAA") to appoint an
arbitrator experienced in the area of dispute who does not have an ongoing
business relationship with any of the parties to the dispute. If the arbitrator
selected informs the parties he cannot hear and resolve the Claim within the
time-frame specified below, the Executive and the Board shall request the
appointment of another arbitrator by the AAA subject to the same requirements.

                  3. Arbitration Procedure. The following procedures shall
govern the conduct of any arbitration under this section. All procedural matters
relating to the conduct of the arbitration other than those specified below
shall be discussed among counsel for the parties and the arbitrator. Subject to
any agreement of the parties, the arbitrator shall determine all procedural
matters not specified herein.

                  (a) Within 30 days of the service of a Notice of Arbitration,
each party shall afford the other, or its counsel, with reasonable access to
documents and persons relating directly to the issues raised in the Notice of
Arbitration. All documents produced and all copies thereof shall be maintained
as strictly confidential, shall be used for no purpose other than the
arbitration hereunder, and shall be returned to the producing party upon
completion of the arbitration. There shall be no other discovery except that, if
a reasonable need is shown, limited depositions may be allowed in the discretion
of the arbitrator, it being the expressed intention and agreement of each

                                       -1-

<PAGE>   16



party to have the arbitration proceedings conducted and resolved as
expeditiously, economically and fairly as reasonably practicable, and with the
maximum degree of confidentiality.

                  (b) All written communications regarding the proceeding sent
to the arbitrator shall be sent simultaneously to each party or its counsel,
with a copy to the Additional Notice Parties. Oral communications between any of
the parties or their counsel and the arbitrator shall be conducted only when all
parties or their counsel are present and participating in the conversation.

                  (c) Within 20 days of selection of the arbitrator, the
Claimant shall submit to the arbitrator a copy of the Notice of Arbitration,
along with a supporting memorandum and any exhibits or other documents
supporting the Claim.

                  (d) Within 20 days of receipt of the Claimant's submission,
the Opposing Party shall submit to the arbitrator a memorandum supporting its
position and any exhibits or other supporting documents. If the Opposing Party
fails to respond to any of the issues raised by the Claimant within 20 days of
receipt of the Claimant's submission, then the arbitrator may find for the
Claimant on any such issue and bar any subsequent consideration of the matter.

                  (e) Within 20 days of receipt of the Opposing Party's
response, the Claimant may submit to the arbitrator a reply to the Opposing
Party's response, or notification that no reply is forthcoming.

                  (f) Within 10 days of the latest submission as provided above,
the arbitrator shall notify the parties and the Additional Notice Parties of the
date of the hearing on the issues raised by the Claim. Scheduling of the hearing
shall be within the sole discretion of the arbitrator, but in no event more than
30 days after the last submission by the parties, and shall take place within 50
miles of the corporate headquarters of the Company at a place selected by the
arbitrator or such other place as is mutually agreed. Both parties shall be
granted substantially equal time to present evidence at the hearing. The hearing
shall not exceed one business day, except for good cause shown.

                  (g) Within 30 days of the conclusion of the hearing, the
arbitrator shall issue a written decision to be delivered to both parties and
the Additional Notice Parties (the "Final Determination"). The Final
Determination shall address each issue disputed by the parties, state the
arbitrator's findings and reasons therefor, and state the nature and amount of
any damages, compensation or other relief awarded.

                  (h) The award rendered by the arbitrator shall be final and
non-appealable and judgment may be entered upon it in accordance with applicable
law in such court as has jurisdiction thereof.

                  4. Costs of Arbitration. As part of the Final Determination,
the arbitrator shall determine the allocation of the costs and expenses of the
arbitration, including the arbitrator's fee and

                                       -2-

<PAGE>   17


both parties' attorneys' fees and expenses, based upon the extent to which each
party prevailed in the arbitration. In the event that any relief which is
awarded is non-monetary, then such costs and expenses shall be allocated in any
manner as may be determined by the arbitrators.

                  5. Satisfaction of Award. If any party fails to pay the amount
of the award, if any, assessed against it within 30 days of the delivery to such
party of the Final Determination, the unpaid amount shall bear interest from the
date of such delivery at the lesser of (i) prime lending rate announced by
Citibank N.A. plus three hundred basis points and (ii) the maximum rate
permitted by applicable usury laws. In addition, such party shall promptly
reimburse the other party for any and all costs or expenses of any nature or
kind whatsoever (including attorneys' fees) reasonably incurred in seeking to
collect such award or to enforce any Final Determination.

                  6. Confidentiality of Proceedings. The parties hereto agree
that all of the arbitration proceedings provided for herein, including any
notice of claim, the Notice of Arbitration, the submissions of the parties, and
the Final Determination issued by the arbitrator, shall be confidential and
shall not be disclosed at any time to any person other than the parties, their
representatives, the arbitrator and the Additional Notice Parties; provided,
however, that this provision shall not prevent the party prevailing in the
arbitration from submitting the Final Determination to a court for the purpose
of enforcing the award, subject to comparable confidentiality protections if the
court agrees; and further provided that the foregoing shall not prohibit
disclosure to the minimum extent reasonably necessary to comply with (i)
applicable law (or requirement having the force of law), court order, judgment
or decree, including, without limitation, disclosures which may be required
pursuant to applicable securities laws, and (ii) the terms of contractual
arrangements (such as financing arrangements) to which the Company or any
Additional Notice Party may be subject so long as such contractual arrangements
were not entered into for the primary purpose of permitting disclosure which
would otherwise be prohibited hereunder.

(1)  The pro forma ratio of earnings to fixed charges is based upon the
application of pro forma adjustments to the historical financial statements of
LISN, Orius and Acquired Businesses.  Pro forma adjustments have been made to
reflect the sale of the notes and the application of the net proceeds which were
used to refinance portions of existing indebtedness.  In addition, adjustments
to reflect the application of purchase accounting to Acquired Businesses and the
elimination of certain non recurring expenses have been reflected.

                     INSTRUCTIONS TO LETTER OF TRANSMITTAL

                    FORMING PART OF THE TERMS AND CONDITIONS
                             OF THE EXCHANGE OFFER

     1.  DELIVERY OF THIS LETTER OF TRANSMITTAL AND NOTES.  A properly completed
and duly executed copy of this Letter of Transmittal, including Substitute Form
W-9, and any other documents required by this Letter of Transmittal must be
received by the Exchange Agent at its address set forth herein, and either
certificates for Tendered Notes must be received by the Exchange Agent at its
address set forth herein or such Tendered Notes must be transferred pursuant to
the procedures for book-entry transfer described in the Prospectus under the
caption "Exchange Offer -- Procedures for Tendering" (and a confirmation of such
transfer received by the Exchange Agent), in each case prior to 5:00 p.m., New
York City time, on the Expiration Date. The method of delivery of certificates
for Tendered Notes, this Letter of Transmittal and all other required documents
to the Exchange Agent is at the election and risk of the tendering holder and
the delivery will be deemed made only when actually received by the Exchange
Agent. If delivery is by mail, registered mail with return receipt requested,
properly insured, is recommended. Instead of delivery by mail, it is recommended
that the Holder use an overnight or hand delivery service. In all cases,
sufficient time should be allowed to assure timely delivery. No Letter of
Transmittal or Notes should be sent to the Issuers. Neither the Issuers nor the
registrar is under any obligation to notify any tendering holder of the Issuers'
acceptance of Tendered Notes prior to the closing of the Exchange Offer.

     2.  GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender their Notes
but whose Notes are not immediately available, and who cannot deliver their
Notes, this Letter of Transmittal or any other documents required hereby to the
Exchange Agent prior to the Expiration Date must tender their Notes according to
the guaranteed delivery procedures set forth below, including completion of Box
4. Pursuant to such procedures: (i) such tender must be made by or through a
firm which is a member of a recognized Medallion Program approved by the
Securities Transfer Association Inc. (an "Eligible Institution") and the Notice
of Guaranteed Delivery must be signed by the holder; (ii) prior to the
Expiration Date, the Exchange Agent must have received from the holder and the
Eligible Institution a properly completed and duly executed Notice of Guaranteed
Delivery (by mail, hand delivery or facsimile transmission) setting forth the
name and address of the holder, the certificate number(s) of the Tendered Notes
and the principal amount of Tendered Notes, stating that the tender is being
made thereby and guaranteeing that, within five New York Stock Exchange trading
days after the Expiration Date, this Letter of Transmittal together with the
certificate(s) representing the Notes and any other required documents will be
deposited by the Eligible Institution with the Exchange Agent; and (iii) such
properly completed and executed Letter of Transmittal, as well as all other
documents required by this Letter of Transmittal and the certificate(s)
representing all Tendered Notes in proper form for transfer, must be received by
the Exchange Agent within five New York Stock Exchange trading days after the
Expiration Date. Any holder who wishes to tender Notes pursuant to the
guaranteed delivery procedures described above must ensure that the Exchange
Agent receives the Notice of Guaranteed Delivery relating to such Notes prior to
5:00 p.m., New York City time, on the Expiration Date. Failure to complete the
guaranteed delivery procedures outlined above will not, of itself, affect the
validity or effect a revocation of any Letter of Transmittal form properly
completed and executed by an Eligible Holder who attempted to use the guaranteed
delivery process.

     3.  BENEFICIAL OWNER INSTRUCTIONS TO REGISTERED HOLDERS.  Only a holder in
whose name Tendered Notes are registered on the books of the registrar (or the
legal representative or attorney-in-fact of such registered holder) may execute
and deliver this Letter of Transmittal. Any Beneficial Owner of Tendered Notes
who is not the registered holder must arrange promptly with the registered
holder to execute and deliver this Letter of Transmittal on his or her behalf
through the execution and delivery to the registered holder of the Instructions
to Registered Holder and/or Book-Entry Transfer Facility Participant from
Beneficial Owner form accompanying this Letter of Transmittal.
<PAGE>   9

     4.  PARTIAL TENDERS.  Tenders of Notes will be accepted only in integral
multiples of $1,000 in principal amount. If less than the entire principal
amount of Notes held by the holder is tendered, the tendering holder should fill
in the principal amount tendered in the column labeled "Aggregate Principal
Amount Tendered" of the box entitled"Description of Notes Tendered" (Box 1)
above. The entire principal amount of Notes delivered to the Exchange Agent will
be deemed to have been tendered unless otherwise indicated. If the entire
principal amount of all Notes held by the holder is not tendered, then Notes for
the principal amount of Notes not tendered and Exchange Notes issued in exchange
for any Notes tendered and accepted will be sent to the Holder at his or her
registered address, unless a different address is provided in the appropriate
box on this Letter of Transmittal, as soon as practicable following the
Expiration Date.

     5.  SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES.  If this Letter of Transmittal is signed by the
registered holder(s) of the Tendered Notes, the signature must correspond with
the name(s) as written on the face of the Tendered Notes without alteration,
enlargement or any change whatsoever.

     If any of the Tendered Notes are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal. If any Tendered
Notes are held in different names, it will be necessary to complete, sign and
submit as many separate copies of the Letter of Transmittal as there are
different names in which Tendered Notes are held.

     If this Letter of Transmittal is signed by the registered holder(s) of
Tendered Notes, and Exchange Notes issued in exchange therefor are to be issued
(and any untendered principal amount of Notes is to be reissued) in the name of
the registered holder(s), then such registered holder(s) need not and should not
endorse any Tendered Notes, nor provide a separate bond power. In any other
case, such registered holder(s) must either properly endorse the Tendered Notes
or transmit a properly completed separate bond power with this Letter of
Transmittal, with the signature(s) on the endorsement or bond power guaranteed
by an Eligible Institution.

     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of any Tendered Notes, such Tendered Notes must be endorsed
or accompanied by appropriate bond powers, in each case, signed as the name(s)
of the registered holder(s) appear(s) on the Tendered Notes, with the
signature(s) on the endorsement or bond power guaranteed by an Eligible
Institution.

     If this Letter of Transmittal or any Tendered Notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations, or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing and, unless waived by the
Issuers, evidence satisfactory to the Issuers of their authority to so act must
be submitted with this Letter of Transmittal.

     Endorsements on Tendered Notes or signatures on bond powers required by
this Instruction 5 must be guaranteed by an Eligible Institution.

     Signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution unless the Tendered Notes are tendered (i) by a registered holder
who has not completed the box set forth herein entitled "Special Delivery
Instructions" (Box 3) or (ii) by an Eligible Institution.

     6.  SPECIAL DELIVERY INSTRUCTIONS.  Tendering holders should indicate, in
the applicable box (Box 3), the name and address to which the Exchange Notes
and/or substitute Notes for principal amounts not tendered or not accepted for
exchange are to be sent, if different from the name and address of the person
signing this Letter of Transmittal. In the case of issuance in a different name,
the taxpayer identification or social security number of the person named must
also be indicated.

     7.  TRANSFER TAXES.  The Issuers will pay all transfer taxes, if any,
applicable to the exchange of Tendered Notes pursuant to the Exchange Offer. If,
however, a transfer tax is imposed for any reason other than the transfer and
exchange of Tendered Notes pursuant to the Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or on any
other person) will be
<PAGE>   10

payable by the tendering holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with this Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
holder.

     Except as provided in this Instruction 7, it will not be necessary for
transfer tax stamps to be affixed to the Tendered Notes listed in this Letter of
Transmittal.

     8.  TAX IDENTIFICATION NUMBER.  Federal income tax law requires that the
holder(s) of any Tendered Notes which are accepted for exchange must provide the
Issuers (as payor) with its correct taxpayer identification number ("TIN"),
which, in the case of a holder who is an individual, is his or her social
security number. If the Issuers are not provided with the correct TIN, the
Holder may be subject to backup withholding and a $50 penalty imposed by the
Internal Revenue Service. (If withholding results in an over-payment of taxes, a
refund may be obtained.) Certain holders (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. See the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.

     To prevent backup withholding, each holder of Tendered Notes must provide
such holder's correct TIN by completing the Substitute Form W-9 set forth
herein, certifying that the TIN provided is correct (or that such holder is
awaiting a TIN), and that (i) the holder has not been notified by the Internal
Revenue Service that such holder is subject to backup withholding as a result of
failure to report all interest or dividends or (ii) the Internal Revenue Service
has notified the holder that such holder is no longer subject to backup
withholding. If the Tendered Notes are registered in more than one name or are
not in the name of the actual owner, consult the "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for information on
which TIN to report.

     The Issuers reserve the right in their sole discretion to take whatever
steps are necessary to comply with the Issuers' obligation regarding backup
withholding.

     9. VALIDITY OF TENDERS.  All questions as to the validity, form,
eligibility (including time of receipt), acceptance and withdrawal of Tendered
Notes will be determined by the Issuers in their sole discretion, which
determination will be final and binding. The Issuers reserve the right to reject
any and all Notes not validly tendered or any Notes the Issuers' acceptance of
which would, in the opinion of the Issuers or their counsel, be unlawful. The
Issuers also reserve the right to waive any conditions of the Exchange Offer or
defects or irregularities in tenders of Notes as to any ineligibility of any
holder who seeks to tender Notes in the Exchange Offer. The interpretation of
the terms and conditions of the Exchange Offer (including this Letter of
Transmittal and the instructions hereto) by the Issuers shall be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Notes must be cured within such time as the Issuers
shall determine. Neither the Issuers, the Exchange Agent nor any other person
shall be under any duty to give notification of defects or irregularities with
respect to tenders of Notes, nor shall any of them incur any liability for
failure to give such notification. Tenders of Notes will not be deemed to have
been made until such defects or irregularities have been cured or waived. Any
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, unless otherwise
provided in this Letter of Transmittal, as soon as practicable following the
Expiration Date.

     10. WAIVER OF CONDITIONS.  The Issuers reserve the absolute right to amend,
waive or modify any of the conditions in the Exchange Offer in the case of any
Tendered Notes.

     11. NO CONDITIONAL TENDER.  No alternative, conditional, irregular, or
contingent tender of Notes or transmittal of this Letter of Transmittal will be
accepted.

     12. MUTILATED, LOST, STOLEN OR DESTROYED NOTES.  Any tendering Holder whose
Notes have been mutilated, lost, stolen or destroyed should contact the Exchange
Agent at the address indicated herein for further instructions.
<PAGE>   11

     13. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and requests
for assistance and requests for additional copies of the Prospectus or this
Letter of Transmittal may be directed to the Exchange Agent at the address
indicated herein. Holders may also contact their broker, dealer, commercial
bank, trust company or other nominee for assistance concerning the Exchange
Offer.

     14. ACCEPTANCE OF TENDERED NOTES AND ISSUANCE OF NOTES; RETURN OF
NOTES.  Subject to the terms and conditions of the Exchange Offer, the Issuers
will accept for exchange all validly tendered Notes as soon as practicable after
the Expiration Date and will issue Exchange Notes therefor as soon as
practicable thereafter. For purposes of the Exchange Offer, the Issuers shall be
deemed to have accepted tendered Notes when, as and if the Issuers have given
written or oral notice (immediately followed in writing) thereof to the Exchange
Agent. If any Tendered Notes are not exchanged pursuant to the Exchange Offer
for any reason, such unexchanged Notes will be returned, without expense, to the
undersigned at the address shown in Box 1 or at a different address as may be
indicated herein under "Special Delivery Instructions" (Box 3).

     15. WITHDRAWAL.  Tenders may be withdrawn only pursuant to the procedures
set forth in the Prospectus under the caption "The Exchange Offer -- Procedures
for Tendering -- Withdrawal of Tenders."
