                               PROSPECTUS SUMMARY
  The following summary highlights selected information from this Prospectus
and may not contain all of the information that is important to you. This Pro-
spectus includes specific terms of the notes we are offering, as well as infor-
mation regarding the business of the guarantor of the notes and detailed finan-
cial data. We encourage you to read this Prospectus in its entirety.
 
                       THE PRIVATE OFFERING OF YOUR NOTES
 
  Coaxial Communications of Central Ohio, Inc. ("Coaxial") and Phoenix Associ-
ates ("Phoenix") completed on August 21, 1998 a private offering of
$140,000,000 aggregate principal amount of their 10% Senior Notes due 2006 in
connection with the "Financing Plan" discussed below, which included the acqui-
sition by Insight Communications of Central Ohio, LLC ("Insight Ohio") of sub-
stantially all of the assets comprising the cable television system (the "Sys-
tem") of Coaxial. As a result of this transaction, Coaxial and Phoenix have
only nominal assets except for Coaxial's ownership of voting preferred and non-
voting common membership interests in Insight Ohio. Coaxial and Phoenix do not
conduct any business. The notes are guaranteed on a conditional basis by In-
sight Ohio.
 
                               THE EXCHANGE OFFER
 
  Coaxial, Phoenix and Insight Ohio entered into a Senior Notes Registration
Rights Agreement with CIBC Oppenheimer Corp. ("CIBC"), the initial purchaser in
the private offering, in which they agreed, among other things, to deliver to
you this Prospectus and to complete the Exchange Offer on or prior to February
17, 1999. You are entitled to exchange in the Exchange Offer your notes for
registered notes with substantially identical terms. If the Exchange Offer is
not completed on or prior to February 17, 1999, the interest rate on your notes
will be increased until the Exchange Offer is completed. You should read the
discussion under the heading "Summary of Terms of the Exchange Notes" and "De-
scription of the Notes" for further information regarding the registered notes.
 
  We believe that the notes issued in the Exchange Offer may be resold by you
without compliance with the registration and prospectus delivery provisions of
the Securities Act of 1933, subject to certain conditions. You should read the
discussion under the headings "Summary of the Exchange Offer" and "The Exchange
Offer" for further information regarding the Exchange Offer and the resale of
notes.
 
          SEPARATE EXCHANGE OFFER BY AFFILIATES OF COAXIAL AND PHOENIX
 
  Simultaneously with the closing of the private offering of your notes and
also in connection with the Financing Plan, one of the owners of Coaxial ("Co-
axial LLC") and an affiliated corporation ("Coaxial Financing Corp.") completed
a private offering of 12 7/8% Senior Discount Notes due 2008 (the "Discount
Notes"). The Discount Notes are also guaranteed on a conditional basis by In-
sight Ohio, subordinated to the conditional guarantee of your notes. During the
same time as the Exchange Offer, Coaxial LLC and Coaxial Financing Corp. will
be conducting an exchange offer of the Discount Notes on terms similar to the
Exchange Offer.
 
                      BACKGROUND OF THE PRIVATE OFFERINGS
 
  The private offerings of your notes and the Discount Notes were part of a fi-
nancing plan (the "Financing Plan") implemented to facilitate the organization
of Insight Ohio, the acquisition of the System by Insight Ohio and to provide
for the System's liquidity and operational
 
                                       1

and financial flexibility. Under of the Financing Plan:
 
 . Coaxial contributed to Insight Ohio substantially all of the assets compris-
  ing the System for which Coaxial received a 25% non-voting common membership
  interest in Insight Ohio as well as voting preferred membership interests in
  Insight Ohio;
 
 . Insight contributed $10.0 million in cash to Insight Ohio for which it re-
  ceived a 75% non-voting common membership interest in Insight Ohio;
 . Coaxial and Phoenix effected the private offering of your notes;
 
 . Coaxial LLC and Coaxial Financing Corp. effected the private offering of the
  Discount Notes; and
 
 . a portion of the existing indebtedness of Coaxial and Phoenix and certain of
  their affiliates, including settlement of related party balances, was repaid
  and the balance was purchased.
 
  The private offerings of your notes and the Discount Notes were consummated
concurrently with the consummation of each of the other components of the Fi-
nancing Plan. Insight Ohio expects shortly to enter into a $25 million senior
credit facility (the "Senior Credit Facility") for the purpose of financing its
future working capital requirements, including the upgrade of the System's ca-
ble plant and the introduction of new video services. You should read the dis-
cussion under "Use of Proceeds," "Management's Discussion and Analysis of Fi-
nancial Condition and Results of Operations--Liquidity and Capital Resources"
and "Description of Certain Indebtedness--Senior Credit Facility" for further
information regarding the Financing Plan and the Senior Credit Facility.
 
                            THE INSIGHT OHIO SYSTEM
 
 Overview
 
  Insight Ohio was formed for the purpose of acquiring Coaxial's cable televi-
sion system in the Columbus, Ohio metropolitan area. As of June 30, 1998, the
System passed approximately 168,600 homes and served approximately 91,100 basic
subscribers in the eastern portion of the City of Columbus and the surrounding
suburban communities. All of the System's subscribers are served from a single
headend allowing for efficient capital deployment for new services. Columbus,
located in the 34th largest geographic television advertising market or desig-
nated market area (DMA) in the United States, is the capital of Ohio and home
of The Ohio State University.
 
 Manager of Insight Ohio
 
  Insight Holdings of Ohio, LLC, a wholly-owned subsidiary of Insight Communi-
cations Company, L.P. (together referred to as "Insight"), serves as the man-
ager of the System. After its pending transactions, Insight will be one of the
top 20 cable television operators in the United States. At the conclusion of
all of its currently signed transactions, Insight management estimates that In-
sight will own or manage cable television systems with 525,000 subscribers in
seven states with over 90% of the subscribers clustered in Illinois, Indiana
and Ohio. You should read the discussion under "Business--The Manager" and "--
Insight Business Strategy" for further information regarding Insight and its
business strategies.
 
 Operating Strategy of Insight Ohio
 
  Portions of the System operate in a competitive environment. Subscribers in
those areas have access to two wired cable television providers--the System and
a cable subsidiary of Ameritech Corporation ("Ameritech"), the telephone local
exchange carrier for Columbus. The areas of the System that are also served by
 
                                       2
<PAGE>
 
Ameritech pass approximately 120,000 homes, representing 71% of the System's
total homes passed.
 
  The prior strategy to compete with Ameritech has included the following:
 
 . selectively constructing fiber optic cable deeper into areas where the Sys-
  tem and Ameritech compete to create additional channel capacity;
 
 . adding more movies, music, news, live sports and exclusive programming such
  as TV Land and Central Ohio Sport! Television on the higher bandwidth;
 
 . decreasing the System's standard rate to be slightly below that offered by
  Ameritech;
 
 . repackaging the System's pay services and selectively using promotions;
 
 . significantly increasing the use of focused target marketing; and
 
 . stressing local customer service.
 
  In addition, Insight intends to aggressively implement its own upgrade
strategy in Columbus, which includes the following:
 
 . increasing channel capacity in order to broaden core analog service
  offerings;
 
 . adding new services such as digital cable, high-speed modems and other newly
  developing telecommunications services as upgrades are completed;
 
 . repackaging channel offerings to more advantageously compete without reduc-
  ing revenue per subscriber;
 
 . utilizing its relationship with MediaOne (formerly Continental Cablevision),
  to provide programming discounts; and
 
 . implementing additional cost savings measures, including specific employee
  reductions.
 
                            MEMBERS OF INSIGHT OHIO
 
  Insight owns 75% of the non-voting common membership interests and Coaxial
owns 25% of the non-voting common membership interests in Insight Ohio. Coax-
ial also owns two separate series of voting preferred membership interests of
Insight Ohio (the "Series A Preferred Interests" and the "Series B Preferred
Interests") which provide for distributions to Coaxial. The distributions from
the Series A Preferred Interests will be used to pay the principal and inter-
est on your notes and the notes to be issued in the Exchange Offer. The dis-
tributions from the Series B Preferred Interests will be used to pay the prin-
cipal and interest on the Discount Notes and the Discount Notes to be issued
in the exchange offer being conducted by Coaxial LLC and Coaxial Financing
Corp. The ability of Insight Ohio to make such preferred distributions will be
subject to certain financial covenants and other conditions in the Senior
Credit Facility.
 
  Insight also serves as manager of Insight Ohio and each of the three limited
liability companies that own Coaxial (the "Individual LLCs"), and thereby has
effective control of the management and affairs of the Individual LLCs, Coax-
ial and Insight Ohio. Insight will not have any liability for your notes or
the notes to be issued in the Exchange Offer.

Registration Rights            You are entitled to exchange your notes for
Agreement....................  registered notes with substantially identical
                               terms. The Exchange Offer is intended to sat-
                               isfy these rights. After the Exchange Offer is
                               complete, you will no longer be entitled to any
                               exchange or registration rights with respect to
                               your notes.
 
The Exchange Offer...........  We are offering to exchange $1,000 principal
                               amount of our 10% Senior Notes due 2006, which
                               have been registered under the Securities Act
                               of 1933, for each $1,000 principal amount of
                               our outstanding 10% Senior Notes due 2006 which
                               were issued on August 21, 1998 in the private
                               offering. In order to be exchanged, an
                               outstanding note must be properly tendered and
                               accepted. All outstanding notes that are
                               validly tendered and not withdrawn will be
                               exchanged.
 
                               As of this date there are $140 million
                               principal amount of notes outstanding.
 
                               We will issue registered notes on or promptly
                               after the expiration of the Exchange Offer.
 
Resale.......................  We believe that the 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 of
                               1933 provided that:
 
                                   . the notes issued in the Exchange Offer
                                     are being acquired in the ordinary course
                                     of your business;
 
                                   . you are not participating, and have no
                                     arrangement or understanding with any
                                     person to participate, in the distribu-
                                     tion of the notes issued to you in the
                                     Exchange Offer; and
 
                                   . you are not an "affiliate" of Coaxial,
                                     Phoenix or Insight Ohio.
 
                               If our belief is inaccurate and you transfer
                               any note issued to you in the Exchange Offer

ing notes and both the outstanding notes and the notes to be issued are gov-
erned by the same indenture (the "Indenture").

                               of payment to all secured indebtedness of the
                               Guarantors to the extent of the value of the
                               assets securing such indebtedness, including
                               indebtedness under the Senior Credit Facility
                               to be entered into by Insight Ohio. In addi-
                               tion, the notes will be effectively subordi-
                               nated to all indebtedness of the subsidiaries
                               of Coaxial and Phoenix that are not Guarantors.

                               any such redemption and that any such redemp-

in its entirety by reference to the actual document.
 
  Following the Exchange Offer, we will be required to file periodic reports

Our obligation to file periodic reports with the SEC will be suspended if the

nevertheless requires us to file with the SEC financial and other information
for public availability. In addition, the indenture governing the notes
requires us to deliver to you, or to Bank of Montreal Trust Company for
forwarding to you, copies of all reports that we file with the SEC without any
cost to you. We will also furnish such other reports as we may determine or as
the law requires.

hibits, and any reports, statements or other information that we file at the

                   SUMMARY HISTORICAL AND COMBINED PRO FORMA
                          FINANCIAL AND OPERATING DATA
 
  The following tables present summary historical financial data for Coaxial
and Phoenix for the three years ended December 31, 1997, which have been de-
rived from the audited financial statements of Coaxial and Phoenix, and unau-
dited historical financial data for the six months ended June 30, 1997 and
1998, which have been derived from the unaudited interim financial statements
of Coaxial and Phoenix. In the opinion of management, such unaudited financial
statements have been prepared on the same basis as the audited financial state-
ments and include all normal and recurring adjustments and accruals necessary
for a fair presentation of such information. Financial results for the six
months ended June 30, 1998 are not necessarily indicative of the results that
may be expected for the full year.
 
  In addition, the following tables present unaudited combined summary pro
forma financial data for Coaxial and Phoenix for the year ended December 31,
1997 and as of and for the six months ended June 30, 1998, as adjusted to give
pro forma effect to the Financing Plan and certain other adjustments, in the
case of the statement of operations and other financial and operating data as
if they had occurred on the first day of the respective periods, and in the
case of balance sheet data as if they had occurred as of such date.
 
  The unaudited combined summary pro forma financial data have been prepared by
the management of Coaxial and Phoenix based upon their historical financial
statements and do not purport to represent what the results of operations or
financial condition of Coaxial and Phoenix would have actually been or what op-
erations in any future period would be if the transactions that give rise to
the pro forma adjustments had occurred on the dates assumed. Management be-
lieves that the combined pro forma data is a meaningful presentation because
Phoenix has no operations for the presented periods, and the ability of Coaxial
and Phoenix to satisfy debt and other obligations is dependent upon cash flow
from the System. The following information is qualified by reference to and
should be read in conjunction with "Selected Historical and Combined Pro Forma
Financial and Operating Data," "Capitalization," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Pro Forma Finan-
cial Statements" and the financial statements and notes thereto included else-
where in this Prospectus.

               NOTES TO SUMMARY HISTORICAL AND COMBINED PRO FORMA
                          FINANCIAL AND OPERATING DATA
 
 (1) Represents EBITDA (as defined below in Note 3) plus home office expense
     for periods prior to the acquisition by Insight Ohio of the System (the
     "System Acquisition"), and EBITDA plus management fees for periods after
     or which give effect to the System Acquisition. Management believes that
     System Cash Flow is a meaningful measure of performance because it is com-
     monly used in the cable television industry to analyze and compare cable
     television companies on the basis of operating performance, leverage and
     liquidity. However, System Cash Flow is not intended to be a performance
     measure that should be regarded as an alternative to, or more meaningful
     than, either operating income or net income as an indicator of operating
     performance or cash flows as a measure of liquidity, as determined in ac-
     cordance with generally accepted accounting principles. System Cash Flow,
     as computed by management, is not necessarily comparable to similarly ti-
     tled amounts of other companies. See the financial statements, including
     the Statements of Cash Flows, included elsewhere in this Prospectus.
 
 (2) Represents results for the three months ended June 30 multiplied by four.
 
 (3) Represents net income before depreciation, amortization, interest expense,
     other expenses and gain on settlement of limited partners. Management be-
     lieves that EBITDA is a meaningful measure of performance because it is
     commonly used in the cable television industry to analyze and compare ca-
     ble television companies on the basis of operating performance, leverage
     and liquidity. However, EBITDA is not intended to be a performance measure
     that should be regarded as an alternative to, or more meaningful than, ei-
     ther operating income or net income as an indicator of operating perfor-
     mance or cash flows as a measure of liquidity, as determined in accordance
     with generally accepted accounting principles. EBITDA, as computed by man-
     agement, is not necessarily comparable to similarly titled amounts of
     other companies. See the financial statements, including the Statements of
     Cash Flows, included elsewhere in this Prospectus.
 
 (4) Represents EBITDA plus launch fees, which are deferred and amortized over
     the applicable contract period for financial reporting purposes. Adjusted
     EBITDA for the six months ended June 30, 1998 and Annualized Adjusted
     EBITDA includes approximately $848,000 of launch fees.
 
 (5) For purposes of calculating the ratio of earnings to fixed charges, earn-
     ings include income (loss) before extraordinary items plus interest ex-
     pense (which includes amortization of debt issuance costs). Fixed charges
     consist of interest expense incurred (including amortization of debt issu-
     ance costs) and the estimated interest component of rent expense (approxi-
     mately one-third). For Phoenix, earnings were inadequate to cover fixed
     charges by $12.4 million, $12.5 million and $8.8 million for the years
     ended December 31, 1995, 1996 and 1997, respectively, and by $5.8 million
     and $6.5 million for the six months ended June 30, 1997 and 1998, respec-
     tively.
 
 (6) Refers to estimates by management of the approximate number of dwelling
     units in a particular community that can be connected to the System.
 
                                       17

 (7) A home with one or more television sets connected to a cable system is
     counted as one basic subscriber. Bulk accounts are included on an equiva-
     lent basic unit basis in which the total monthly bill for the account is
     divided by the basic monthly charge for a single outlet in the area.
 
 (8) Calculated as basic subscribers as a percentage of homes passed.
 
 (9) Includes only single channel services offered for a monthly fee per chan-
     nel and does not include tiers of channels offered as a package for a sin-
     gle monthly fee. A subscriber may purchase more than one premium service,
     each of which is counted as a separate premium service unit.
 
(10) Calculated as premium service units as a percentage of basic subscribers.
 
(11) Represents revenues of the System during the respective period divided by
     the months in the period divided by the average number of basic subscrib-
     ers (beginning of period plus end of period divided by two) for such re-
     spective period.
 
(12) Represents Annualized System Cash Flow during the respective period di-
     vided by the average number of basic subscribers (beginning of period plus
     end of period divided by two) for such respective period.
 
(13) Represents Annualized Adjusted EBITDA during the respective period divided
     by the average number of basic subscribers (beginning of period plus end
     of period divided by two) for such respective period.
 
(14) Management believes that the following adjustments to historical
     annualized EBITDA for the three months ended June 30, 1998 are relevant to
     evaluating the operating performance of the System. These annualized pro
     forma adjustments reflect: (i) programming rate savings from MediaOne;
     (ii) headcount reductions primarily due to duplication within the finance
     and accounting departments; (iii) elimination of rent expense due to the
     contribution of an office building to the System as part of the Contribu-
     tion Agreement; (iv) elimination of home office expenses relating to
     Coaxial's owners; and (v) management fees to be paid to Insight. Manage-
     ment believes these adjustments to be reasonable. In addition, annualized
     pro forma adjusted EBITDA reflects a supplemental adjustment for launch
     fees for Fox News and Great American Country. The System has received
     launch fees in the past, and management believes it will continue to re-
     ceive launch fees in the normal course of business.

                                 RISK FACTORS
 
  An investment in the registered notes to be issued pursuant to this
Prospectus (the "Exchange Notes") is subject to a number of risks. You should
carefully consider the following factors, as well as the more detailed
descriptions cross-referenced to the body of this Prospectus and the other
matters described in this Prospectus, in evaluating Coaxial, Phoenix
(together, the "Issuers"), Insight Ohio, the Exchange Notes, the System and
the cable television industry. The term "Note" or "Notes" includes the
outstanding notes (the "Original Notes") and the Exchange Notes. Unless
otherwise indicated, the term "Management" includes the management of Insight
and those members of Coaxial management who have remained with the System
since its acquisition by Insight Ohio.
 
HIGHLY LEVERAGED CAPITAL STRUCTURE
 
  The Issuers' ability to make scheduled payments with respect to the Notes
will depend on the financial and operating performance of Insight Ohio. As of
June 30, 1998, on a pro forma basis after giving effect to the Financing Plan,
Insight Ohio would have had outstanding redeemable Series A Preferred Inter-
ests and Series B Preferred Interests (together the "Preferred Interests")
with an aggregate liquidation preference of $170.0 million. The Indenture and
the indenture under which the Discount Notes have been, and the new Discount
Notes are being, issued (the "Discount Notes Indenture") permit Insight Ohio
and its subsidiaries to incur or guarantee additional indebtedness, subject to
certain limitations. In addition, Insight Ohio will have borrowing capacity on
a revolving credit basis under the Senior Credit Facility. See "Description of
Certain Indebtedness--Senior Credit Facility." Insight Ohio is subject to pre-
vailing economic and competitive conditions and to certain financial, business
and other factors beyond its control, including interest rates, increased op-
erating costs and regulatory developments. There can be no assurance that In-
sight Ohio will maintain a level of cash flow from operations necessary to pay
the required distributions on the Preferred Interests and sufficient to permit
the Issuers to pay the principal, premium, if any, and interest on the Notes.
 
  Insight Ohio's high degree of debt service and preferred distribution re-
quirements could have important consequences to the holders of the Notes, in-
cluding, but not limited to, the following:
 
  . Insight Ohio's ability to obtain additional financing for working capi-
    tal, capital expenditures, acquisitions, debt service and preferred dis-
    tribution requirements, general corporate purposes and other purposes may
    be impaired in the future;
 
  . a substantial portion of Insight Ohio's cash flow from operations is re-
    quired to be dedicated to the payment of principal and interest on its
    indebtedness and the required distributions with respect to the Preferred
    Interests, thereby reducing the funds available to Insight Ohio for other
    purposes, including its operations and future business opportunities;
 
  . the indebtedness outstanding under the Senior Credit Facility will be se-
    cured by substantially all of the assets of Insight Ohio and will mature
    prior to the maturity of the Notes; and
 
  . Insight Ohio's leveraged position and the covenants contained in its debt
    instruments could limit its flexibility to adjust to changing market con-
    ditions and ability to withstand competitive pressures, and Insight Ohio
    may be more vulnerable to a downturn in general economic conditions or in
    its business or be unable to carry out capital spending that is important
    to its growth and productivity improvement programs.
 
 
                                      20
<PAGE>
 
  If Insight Ohio's cash flow and capital resources are insufficient to fund
debt service and preferred distribution obligations, Insight Ohio and the Is-
suers may be forced to reduce or delay capital expenditures, sell assets or
seek to obtain additional equity capital or restructure or refinance debt (in-
cluding the Notes). There can be no assurance that such alternative measures
would be successful or would permit Insight Ohio and the Issuers to meet their
scheduled debt service and preferred distribution obligations. In the absence
of such operating results and resources, Insight Ohio could face substantial
liquidity problems and might be required to dispose of material assets or oper-
ations to meet debt service and preferred distribution and other obligations.
Insight Ohio's Operating Agreement, the Indenture and the Discount Notes Inden-
ture restrict, and the Senior Credit Facility is expected to restrict, the Is-
suers' and Insight Ohio's ability to sell assets and use the proceeds there-
from. There can be no assurance as to the ability of the Issuers or Insight
Ohio to consummate such sales or that the proceeds which they could realize
therefrom would be adequate to meet the obligations then due.
 
INSUFFICIENCY OF EARNINGS TO COVER FIXED CHARGES
 
  On a pro forma basis after giving effect to the Financing Plan, the combined
earnings of the Issuers, the Discount Issuers and Insight Ohio would have been
insufficient to cover their combined fixed charges for the six months ended
June 30, 1998 by approximately $1.6 million. The ability of the Issuers to meet
their debt service obligations under the Notes will depend upon the future per-
formance of Insight Ohio and its ability to make the required distributions on
the Preferred Interests which, in turn, is subject to general economic condi-
tions and to financial, competitive, regulatory and other factors, many of
which are beyond its control. Management believes that Insight Ohio will con-
tinue to generate cash and obtain financing sufficient to meet such require-
ments in the future; however, there can be no assurance that the Issuers or In-
sight Ohio will be able to meet their debt service, preferred distribution and
other obligations. If the Issuers and Insight Ohio were unable to do so, they
would have to pursue one or more alternatives, such as refinancing their in-
debtedness or obtaining new financing, reducing or delaying capital expendi-
tures, selling assets of Insight Ohio or raising equity capital financing.
There can be no assurance that the Issuers or Insight Ohio would be able to re-
finance or obtain such new financing in the future or that, if the Issuers or
Insight Ohio were able to do so, the terms available would be favorable to the
Issuers or Insight Ohio. See "Selected Historical and Combined Pro Forma Finan-
cial and Operating Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
CONDITIONAL GUARANTEES; STRUCTURAL SUBORDINATION
 
  The Issuers have no significant assets available to the holders of the Notes
other than Coaxial's common membership interests and Preferred Interests in In-
sight Ohio. The Issuers' ability to make interest and principal payments when
due to holders of the Notes will be dependent upon Coaxial's receipt of suffi-
cient funds from Insight Ohio with respect to the Series A Preferred Interests.
Under the expected terms of the Senior Credit Facility, upon the occurrence of
an event of default or if certain financial performance tests or other condi-
tions are not met, Insight Ohio will be restricted from making distributions on
the Preferred Interests. There can be no assurance that Insight Ohio will be
able to satisfy the financial tests and the related conditions expected to be
set forth in the Senior Credit Facility to make such distributions, or that In-
sight Ohio will not be in default of its financial covenants or otherwise under
the Senior Credit Facility which could prevent the Issuers from making any pay-
ments in respect of the Notes. In addition, because the Guarantors only condi-
tionally guarantee the payment of principal of and interest on the Notes (the
"Guarantees"), the claims of
 
                                       21
<PAGE>
 
holders of the Notes effectively will be, for the most part, subordinated to
all existing and future claims of the creditors of the Guarantors, including
the lenders under the Senior Credit Facility and the Guarantors' trade credi-
tors, until all conditions to which the Guarantees are subject have been sat-
isfied. The ability of the holders of the Notes to realize upon any of Insight
Ohio's (or any other Guarantor's) assets upon its liquidation or reorganiza-
tion will be subject to the prior claims of Insight Ohio's (or any other Guar-
antor's) creditors including the lenders under the Senior Credit Facility un-
til the effectiveness of the Guarantees, which will only be effective to the
extent and at the time the holders of the Notes are unable to realize proceeds
from the enforcement of the mandatory redemption provisions of the Series A
Preferred Interests. The holders of the Notes will be required to prosecute a
claim until adjudication against Insight Ohio for failure to redeem the Series
A Preferred Interests before it can be determined that such a failure to real-
ize proceeds has occurred. This process may entail protracted and time consum-
ing litigation. In addition, the indebtedness outstanding from time to time
under the Senior Credit Facility will be secured by substantially all of the
assets of Insight Ohio and any of its future subsidiaries, and the lenders
thereunder will have a claim on such assets prior to the claims of holders of
the Notes. See "--Certain Bankruptcy Considerations" below, "Management's Dis-
cussion and Analysis of Financial Condition and Results of Operations--Liquid-
ity and Capital Resources," "Description of Certain Indebtedness" and "De-
scription of the Notes."
 
NON-RECOURSE DEBT; ABILITY TO REALIZE ON COLLATERAL
 
  The Notes are non-recourse secured obligations of the Issuers. The Notes are
secured only by a first priority pledge of the issued and outstanding Series A
Preferred Interests of Insight Ohio (the "Senior Notes Collateral") which will
become non-voting upon the enforcement of remedies under the Pledge Agreement.
As non-recourse obligations, the only remedy available to holders will be to
enforce their rights under the Pledge Agreement in respect of the Senior Notes
Collateral. Any remedy will be limited to the value of the Senior Notes Col-
lateral and holders will have no claim against the Issuers for any difference
between amounts due under the Notes and amounts recovered in respect of the
Senior Notes Collateral. If an event of default occurs with respect to the
Notes, there can be no assurance that the liquidation of the Senior Notes Col-
lateral will produce proceeds in an amount sufficient to pay the principal of
or the accrued and unpaid interest, if any, on the Notes. Insight, the manager
of Insight Ohio, has discretion in certain circumstances in accordance with
Insight Ohio's Operating Agreement to make distributions with respect to the
Preferred Interests. See "--Certain Bankruptcy Considerations."
 
RESTRICTIONS IMPOSED BY TERMS OF INDEBTEDNESS
 
  The Indenture and the Discount Notes Indenture impose, and the Senior Credit
Facility is expected to impose, (i) restrictions, that, among other things,
limit the amount of additional indebtedness that may be incurred by the Is-
suers and their subsidiaries (including Insight Ohio) and (ii) limitations on,
among other things, investments, loans and other payments, certain transac-
tions with affiliates and certain mergers and acquisitions. The Senior Credit
Facility also is expected to restrict the ability of Insight Ohio and its sub-
sidiaries to pay dividends or make capital contributions, including distribu-
tions on the Preferred Interests that are required to pay the Notes and Dis-
count Notes in the event of a payment default under the Senior Credit Facili-
ty, and to require Insight Ohio to maintain specified financial ratios and
meet certain financial tests. The ability of Insight Ohio to comply with such
covenants and restrictions can be affected by events beyond its control, and
there can be no assurance that Insight Ohio will achieve operating results
that would permit compliance with such provisions. The breach of certain pro-
visions of the Senior Credit Facility would, under certain circumstances, re-
sult in defaults thereunder, permitting the lenders thereunder to prevent dis-
tributions with respect to the Preferred Interests and to accelerate the in-
debtedness thereunder. If Insight Ohio were
 
                                      22
<PAGE>
 
unable to repay the amounts due in respect of the Senior Credit Facility, the
lenders thereunder could foreclose upon the assets pledged to secure such re-
payment. Any of such events would adversely affect the Issuers' ability to
service the Notes or comply with the redemption provisions of the Series A Pre-
ferred Interests.
 
CERTAIN BANKRUPTCY CONSIDERATIONS
 
 Creditors' Rights
 
  The right of the trustee, which holds the Senior Notes Collateral on behalf
of the holders of the Notes, to repossess and dispose of the collateral upon
the occurrence of an event of default under the Indenture is likely to be sig-
nificantly impaired by applicable bankruptcy law if a bankruptcy case were to
be commenced by or against the Issuers, whether by a holder of the Notes or an-
other creditor, prior to such repossession and disposition. Under applicable
bankruptcy law, secured creditors, such as the holders of the Notes, are auto-
matically stayed from repossessing their security from a debtor in a bankruptcy
case, or from disposing of collateral in their possession, without bankruptcy
court approval. Moreover, applicable bankruptcy law permits the debtor to con-
tinue to retain and use the collateral even though the debtor is in default un-
der the applicable debt instruments, provided that the secured creditor is
given "adequate protection." The meaning of the term "adequate protection" may
vary according to circumstances, but it is intended in general to protect the
secured creditor from diminution in the value of the collateral as a result of
the stay of repossession or disposition or any use of the collateral by the
debtor during the pendency of the bankruptcy case. "Adequate protection" may
include cash payments or the granting of additional security at such time and
in such amount as the court may determine. In view of the lack of a precise
definition of the term "adequate protection," the broad discretionary powers of
a bankruptcy court and the possible complexity of valuation issues, it is im-
possible to predict how long payments under the Notes could be delayed follow-
ing commencement of a bankruptcy case, whether or when the trustee could repos-
sess or dispose of the collateral or whether or to what extent the holders of
the Notes would be compensated for any delay in payment of loss of value of the
collateral through the requirement for "adequate protection."
 
 Limited Liability Companies
 
  Insight Ohio is a limited liability company organized under the laws of the
State of Delaware. Limited liability companies ("LLCs") are relatively recent
creations not only under the laws of the State of Delaware but also under the
laws of other jurisdictions. Generally stated, LLCs are intended to provide
both the limited liability of the corporate form for their members and certain
advantages of partnerships, including "pass-through" income tax treatment for
members, and thus have attributes of both corporations and partnerships. Given
their recent creation, LLCs and their members have been involved in relatively
few bankruptcy cases as debtors, and there has been little reported judicial
authority addressing bankruptcy issues as they pertain to LLCs. Moreover, the
existing judicial authority on such issues in bankruptcies of analogous enti-
ties (e.g., partnerships) is not well settled. Consequently, a bankruptcy of
any LLC, their members or any of their affiliates or a claim with respect to
the collateral may be litigated and decided in the absence of dispositive judi-
cial precedent, and thus, no assurance can be made as to any particular outcome
including with respect to the contractual claims associated with enforcing
rights as a holder of the Preferred Interests after foreclosing on the collat-
eral.

FRAUDULENT CONVEYANCE
 
  Various fraudulent conveyance laws have been enacted for the protection of
creditors and may be utilized by a court to subordinate or avoid the Notes in
favor of other existing or future creditors of the Issuers. If a court in a
lawsuit on behalf of any unpaid creditor of the Issuers or a representative of
the Issuers' creditors were to find that, at the time the Issuers issued the
Notes, the Issuers (x) intended to hinder, delay or defraud any existing or fu-
ture creditor or contemplated insolvency with a design to prefer one or more
creditors to the exclusion in whole or in part of others or (y) did not receive
fair consideration or reasonably equivalent value for issuing the Notes and the
Issuers (i) were insolvent, (ii) were rendered insolvent by reason of such is-
suance, (iii) were engaged or about to engage in a business or transaction for
which their remaining assets constituted unreasonably small capital to carry on
their business or (iv) intended to incur, or believed that they would incur,
debts beyond their ability to pay such debts as they matured, such court could
void the Issuers' obligations under the Notes and void such transactions. Al-
ternatively, in such event, claims of the holders of the Notes could be subor-
dinated to claims of the other creditors of the Issuers. Based upon financial
and other information currently available to them, the Issuers believe that the
Notes are being incurred for proper purposes and in good faith and that the Is-
suers are solvent and will continue to be solvent after issuing the Notes, will
have sufficient capital for carrying on their business after such issuance and
will be able to pay their debts as they mature.
 
  In addition, the Guarantees may be subject to review under relevant federal
and state fraudulent conveyance and similar statutes in a bankruptcy or reorga-
nization case or a lawsuit by or on behalf of creditors of any of the Guaran-
tors. In such a case, the analysis set forth above generally would apply. A
court could avoid a Guarantor's obligation under its Guarantee, subordinate the
Guarantee to other indebtedness of such Guarantor or take other action detri-
mental to the holders of the Notes.
 
SIGNIFICANT CAPITAL EXPENDITURES
 
  Consistent with its business strategy, Management expects to make capital ex-
penditures to upgrade the System over the next several years. Insight Ohio's
potential inability to fund these capital expenditures could adversely affect
its ability to upgrade the System which could have a material adverse effect on
its operations and competitive position. See "Business" and "Management's Dis-
cussion and Analysis of Financial Condition and Results of Operations--Liquid-
ity and Capital Resources."
 
SIGNIFICANT COMPETITION IN THE CABLE TELEVISION INDUSTRY; OVERBUILDS
 
  Cable television systems face competition from alternative methods of receiv-
ing and distributing television signals and from other sources of news, infor-
mation and entertainment, such as off-air television broadcast programming,
newspapers, movie theaters, live sporting events, online computer services and
home video products, including videotape cassette recorders. Because Insight
Ohio's franchises are generally non-exclusive, there is the potential for com-
petition with its systems from others (such as the situation with Ameritech de-
scribed below) including systems operated by local governmental authorities.
Other distribution systems capable of delivering programming to homes or busi-
nesses, including satellite master antenna television service ("SMATV"), direct
broadcast satellite ("DBS") systems and multichannel, multipoint distribution
service ("MMDS") systems now compete with the System. In recent years, there
has been significant national growth in the number of subscribers to DBS serv-
ices and such growth is expected to continue. See "Business--Competition."
 
                                       24
<PAGE>
 
The number of choices available to the System's subscribers as a result of
other distribution systems may lead to a reduction in its market share. There
can be no assurance that the System will be able to obtain or maintain sub-
scribers.
 
  Additionally, recent changes in federal law and recent administrative and ju-
dicial decisions have removed certain of the restrictions that have limited en-
try into the cable television business by potential competitors such as tele-
phone companies, registered utility holding companies and their subsidiaries.
Such developments will enable local telephone companies to provide a wide vari-
ety of video services in the telephone company's own service area which will be
directly competitive with services provided by cable television systems. Other
new technologies, including Internet-based services, may also become competi-
tive with services that cable television operators can offer.
 
  In 1996, Ameritech, the telephone local exchange carrier for Columbus, ob-
tained a citywide cable television franchise for the City of Columbus.
Ameritech began offering cable television service in June 1996 and to date has
substantially built its entire citywide franchise, both in the System's service
area and in the Time Warner service area on the west side of Columbus. The Time
Warner system and the System service virtually distinct areas and therefore do
not compete with each other. The overbuild (as defined in the "Glossary") by
Ameritech passes approximately 71% of the homes passed by the System (approxi-
mately 120,000 homes), effectively allowing approximately 60,000 of the Sys-
tem's basic subscribers to choose between Ameritech and the System. Ameritech
has cable television franchise applications pending in two surrounding communi-
ties covering an additional 2,000 of the System's homes and 1,200 of the Sys-
tem's subscribers. See "Business--Overbuild."
 
  The System competes for advertising revenue with other television programming
services described above, as well as with other national and international ca-
ble television programming services, superstations, broadcast television net-
works, local over-the-air television stations, radio and print media, in addi-
tion to alternative delivery services that now exist or are expected to develop
in the future. More generally, the System competes with various other leisure-
time activities such as home videos, movie theaters, personal computers and
other alternative sources of entertainment and information. See "Business--Com-
petition."
 
  Many of the System's potential competitors have substantially greater re-
sources and Management cannot predict the extent to which competition will ma-
terialize in its franchise areas from other cable television operators, other
distribution systems for delivering video programming and other broadband tele-
communications services to the home, or from other potential competitors, or,
if such competition materializes, the extent of its effect on the System. See
"Business--Competition" and "Legislation and Regulation."
 
RISKS RELATING TO BUSINESS STRATEGY
 
  Management plans to upgrade selectively the System to enhance the potential
for increasing revenues through the introduction of new technologies and serv-
ices, such as cable Internet access and high-speed data transmission. See
"Business--Insight's System Operating Strategy." While Management is optimistic
about the prospects for these new lines of business, there can be no assurance
that it will be able to enter them successfully or to generate additional cash
flow. Moreover, many of these new lines of business are likely to have signifi-
cant competition from businesses that may have substantial financial resources
and market presence such as local telephone companies, long distance
interexchange carriers and traditional online Internet service providers.
 
 
                                       25
<PAGE>
 
  Historically, an element of Insight's strategy has been to swap assets in or-
der to, among other things, geographically consolidate its holdings. Subject to
certain limitations, the Indenture and the Discount Notes Indenture permit as-
set swaps. Management will consider potential opportunities to swap cable tele-
vision systems. There can be no assurance that Management will be able to inte-
grate successfully any acquired systems, realize any efficiencies from any swap
or that any acquisition or swap will improve operating results.
 
RAPID TECHNOLOGICAL ADVANCES
 
  The cable television business is characterized by rapid technological change
and the introduction of new products and services. There can be no assurance
that Insight Ohio will be able to fund the capital expenditures necessary to
keep pace with technological developments or that the System will successfully
anticipate the demand of its subscribers for products or services requiring new
technology. Insight Ohio's inability to provide enhanced services in a timely
manner or to anticipate the demands of the marketplace could have a material
adverse effect on the System's business, results of operations and financial
condition. See "Business--Competition."
 
  In addition, the System's introduction of new technologies or services is
subject to uncertainties regarding subscriber demand, future competition, ap-
propriate pricing, and the costs and timing with respect to marketing and sales
efforts. There can be no assurances as to the effect of such technological
changes on the System's business, results of operations and financial condition
or that Insight Ohio will not be required to expend substantial financial re-
sources to implement new technologies, that capital expenditures for new tech-
nologies or services will approximate Management's expectations, or that suffi-
cient demand exists to recoup such expenditures.
 
NON-EXCLUSIVE FRANCHISES; NON-RENEWAL OR TERMINATION OF FRANCHISES
 
  Cable television companies operate under non-exclusive franchises granted by
local authorities which are subject to renewal and renegotiation from time to
time. A franchise is generally granted for a fixed term ranging from five to
fifteen years, but in many cases is terminable if the franchisee fails to com-
ply with its material provisions. The System's business is dependent upon the
retention and renewal of its local franchises. Franchises typically impose con-
ditions relating to the operation of cable television systems, including re-
quirements relating to the payment of fees, bandwidth capacity, customer serv-
ice requirements, franchise renewal and termination. The Cable Television Con-
sumer Protection and Competition Act of 1992 (the "1992 Cable Act") prohibits
franchising authorities from granting exclusive cable television franchises and
from unreasonably refusing to award additional competitive franchises; it also
permits municipal authorities to operate cable television systems in their com-
munities without franchises. The Cable Communication Policy Act of 1984 (the
"1984 Cable Act" and, together with the 1992 Cable Act, the "Cable Acts") pro-
vides, among other things, for an orderly franchise renewal process in which
franchise renewal will not be unreasonably withheld or, if renewal is denied
and the franchising authority acquires ownership of the system or effects a
transfer of the system to another person, the operator generally is entitled to
the "fair market value" for the system covered by such franchise. Historically,
franchises have been renewed for cable operators that have provided satisfac-
tory services and have complied with the terms of their franchises. Although
Management believes that it generally has good relationships with its franchise
authorities, no assurance can be given that the System will be able to retain
or renew such fran- chises or that the terms of any such renewals will be on
terms as favorable to its existing franchises. Furthermore, it is possible that
a franchise authority might grant a franchise to another cable
 
                                       26
<PAGE>
 
company. The non-renewal or termination of franchises relating to a significant
portion of the Sys- tem would have a material adverse effect on the System's
results of operations. See "Business-- Franchises."
 
REGULATION IN THE CABLE TELEVISION INDUSTRY
 
  The cable television industry is subject to extensive regulation by federal,
local and, in some instances, state governmental agencies. The Cable Acts, both
of which amended the Communications Act of 1934 (as amended, the "Communica-
tions Act"), established a national policy to guide the development and regula-
tion of cable television systems. The Communications Act was recently substan-
tially amended by the Telecommunications Act of 1996 (the "1996 Telecom Act").
Principal responsibility for implementing the policies of the Cable Acts and
the 1996 Telecom Act has been allocated between the FCC and state or local reg-
ulatory authorities. It is not possible to predict the effect that ongoing or
future developments might have on the cable communications industry or on the
operations of the System. See "Legislation and Regulation."
 
 Federal Law and Regulation
 
  The 1992 Cable Act and the FCC's rules implementing such act generally have
resulted in additional regulatory oversight by the FCC and local or state fran-
chise authorities. In addition, they have resulted in increased administrative
and operational expenses for cable television systems. The Cable Acts and the
corresponding FCC regulations have established, among other things:
 
  . rate regulations;
 
  . mandatory carriage and retransmission consent requirements that require a
    cable television system under certain circumstances to carry a local
    broadcast station or to obtain consent to carry a local or distant
    broadcast station;
 
  . rules for franchise renewals and transfers; and
 
  . other requirements covering a variety of operational areas such as equal
    employment opportunity, technical standards and customer service
    requirements.
 
  The 1996 Telecom Act deregulates rates for cable programming services tiers
("CPST") commencing in March 1999 and, for certain small cable operators, imme-
diately eliminates rate regulation of CPST, and, in certain limited circum-
stances, basic services. The FCC is currently developing permanent regulations
to implement the rate deregulation provisions of the 1996 Telecom Act. Manage-
ment is currently unable to predict the ultimate effect of the 1992 Cable Act
or the 1996 Telecom Act.
 
  The FCC and Congress continue to be concerned that rates for regulated pro-
gramming services are rising at a rate exceeding inflation. It is therefore
possible that the FCC will further restrict the ability of cable television op-
erators to implement rate increases and/or Congress will enact legislation
which would, for example, delay or suspend the scheduled March 1999 termination
of CPST rate regulation.
 
 State and Local Regulation
 
  Cable television systems generally operate pursuant to non-exclusive fran-
chises, permits or licenses granted by a municipality or other state or local
governmental entity. The terms and conditions of franchises vary materially
from jurisdiction to jurisdiction. A number of states subject cable
 
                                       27
<PAGE>
 
television systems to the jurisdiction of centralized state governmental agen-
cies. Currently, Ohio, the state in which the System currently operates, has
not enacted state level regulation. Management cannot predict whether such
state will engage in such regulation in the future. See "Legislation and Regu-
lation."
 
DEPENDENCE ON INSIGHT AND KEY PERSONNEL OF INSIGHT
 
  The System's success depends on its management by Insight and, therefore, on
Insight's ability to continue to attract, motivate and retain highly qualified
management, sales and technical personnel. In the event Insight is unable to
continue to do so, the operations and growth prospects of the System could be
adversely affected. In the event Insight were to lose the services of key per-
sonnel, its ability to conduct its business, which will include management of
the System, could be adversely affected. In addition, Insight's management of
cable systems other than the System may limit the availability and accessibil-
ity of certain Insight personnel, which could adversely affect Insight's abil-
ity to manage the System.
 
ABILITY TO PURCHASE NOTES UPON A CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, the Issuers will be required to
make an offer to purchase all outstanding Notes at a purchase price equal to
101% of the principal amount thereof, together with accrued and unpaid inter-
est, if any, to the date of repurchase. If a Change of Control were to occur,
there can be no assurance that the Issuers would have sufficient financial re-
sources, or would be able to arrange financing or be permitted under the terms
of other outstanding or future indebtedness arrangements, to pay the purchase
price for all Notes tendered by holders thereof. In addition, it is expected
that the Senior Credit Facility will include a "change of control" provision
that permits the lenders thereunder to accelerate the repayment of indebtedness
thereunder. It is expected that the Senior Credit Facility will not permit In-
sight Ohio to make distributions so as to permit the Issuers to effect a pur-
chase of the Notes upon a Change of Control without the prior satisfaction of
certain financial tests and other conditions. See "--Conditional Guarantees;
Structural Subordination" above and "Description of Certain Indebtedness." Any
future credit agreements or other agreements relating to other indebtedness to
which Insight Ohio becomes a party may contain similar restrictions and provi-
sions. In the event a Change of Control occurs at a time when the Issuers are
unable to purchase the Notes, the Issuers could seek the consent of their lend-
ers under such indebtedness to repurchase Notes or could attempt to refinance
the borrowings that contain such prohibition. If the Issuers do not obtain such
consent or repay such borrowing, the Issuers would remain prohibited from re-
purchasing the Notes. In such case, the Issuers' failure to repurchase tendered
Notes would constitute an Event of Default under the Indenture. In the event of
a Change of Control, and as a result of the inability of the Issuers to repur-
chase the Notes, the holder of the Notes would have no recourse against the Is-
suers other than any remedies they may have against the collateral or, failing
that, the conditional guarantee of Insight Ohio. See "--Non-Recourse Debt;
Ability to Realize on Collateral."
 
INDUSTRY AND ECONOMIC CONDITIONS
 
  The operating results of the System are subject to various factors that af-
fect the cable television industry as a whole. The System may be affected by
numerous factors, including:
 
  . changes in audience tastes;
 
  . priorities of advertisers;
 
                                       28
<PAGE>
 
  . new laws and governmental regulations and policies;
 
  . changes in technical requirements;
 
  . technological changes;
 
  . proposals to eliminate the tax deductibility of expenses incurred by
    advertisers; and
 
  . changes in the willingness of financial institutions and other lenders to
    finance cable television system acquisitions and operations.
 
  Insight Ohio cannot predict which, if any, of these or other factors might
have a significant impact on the cable television industry in the future, nor
can it predict what impact, if any, the occurrence of these or other events
might have on its operations. Generally, advertising tends to decline during
economic recession or downturn. Consequently, the System's cable television
revenue is likely to be adversely affected by a recession or downturn in the
United States economy or other events or circumstances that adversely affect
advertising activity. In addition, Insight Ohio's operating results in
individual geographic markets could be adversely affected by local regional
economic downturns.
 
ABSENCE OF PUBLIC MARKET; RESTRICTIONS ON TRANSFER
 
  Prior to the Exchange Offer, there was no public market for the Original
Notes. The Original Notes have not been registered under the Securities Act of
1933 (the "Securities Act") and will be subject to restrictions on transfera-
bility 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 Origi-
nal Notes (other than any such holder that is an "affiliate" of the Issuers
and Insight Ohio 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 the Issuers and Insight Ohio are required to file a
Shelf Registration Statement with respect to such Original Notes. The Exchange
Notes will constitute a new issue of securities with no established trading
market. Although CIBC has informed the Issuers that it currently intends to
make a market in the Exchange Notes, it is not obligated to do so and any such
market making may be discontinued at any time without notice in the sole dis-
cretion of CIBC. In addition, such market making activity will be subject to
the limits imposed by the Securities Act and the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and may be limited during the pendency
of the Exchange Offer or the effectiveness of a shelf registration statement
in lieu thereof. Accordingly, there can be no assurance as to the development
or liquidity of any market for the Exchange Notes. The Exchange Notes are ex-
pected to be eligible for trading by qualified buyers in the PORTAL market. If
an active public market does not develop, the market price and liquidity of
the Exchange Notes may be adversely affected. If a trading market develops for
the Exchange Notes, the future trading prices thereof will depend on many fac-
tors including, among other things, Insight Ohio's results of operations, pre-
vailing interest rates, the market for securities with similar terms and the
market for securities of other companies in similar businesses. The Issuers do
not intend to apply for listing of the Exchange Notes on any securities ex-
change or for their quotation through an automated dealer quotation system.
 
  The Original Notes were offered in reliance upon an exemption from registra-
tion under the Securities Act and applicable state securities laws. Therefore,
the Original Notes may be transferred or resold only in a transaction regis-
tered under, or exempt from, the Securities Act and applicable state securi-
ties laws. Pursuant to the Registration Rights Agreement among Coaxial, Phoe-
nix, Insight Ohio and CIBC (the "Registration Rights Agreement"), Coaxial,
Phoenix and Insight Ohio have agreed to file the Exchange Offer Registration
Statement with the SEC and to use their reasonable
 
                                      29
<PAGE>
 
best efforts to cause such registration statement to become effective with re-
spect to the Exchange Notes. After the registration statement becomes effec-
tive, the Exchange Notes generally will be permitted to be resold or otherwise
transferred (subject to the restrictions described under "The Exchange Offer--
Resale of Exchange Notes") by each holder without the requirement of further
registration. The Exchange Notes, however, also will constitute a new issue of
securities with no established trading market and will be issued only in the
amount of Original Notes being tendered for exchange. No assurance can be
given as to the liquidity of the trading market for the Exchange Notes, or, in
the case of non-tendering holders of Original Notes, the trading market for
the Original Notes following the Exchange Offer.
 
FAILURE TO FOLLOW EXCHANGE OFFER PROCEDURES COULD ADVERSELY AFFECT HOLDERS
 
  Issuance of the Exchange Notes in exchange for the Original Notes pursuant
to the Exchange Offer will be made only after a timely receipt by Bank of Mon-
treal Trust Company of such Original Notes, a properly completed and duly exe-
cuted Letter of Transmittal and all other required documents. Therefore, hold-
ers of the Original Notes desiring to tender such Original Notes in exchange
for Exchange Notes should allow sufficient time to ensure timely delivery. The
Issuers are under no duty to give notification of defects or irregularities
with respect to the tenders of Original Notes for exchange. Original Notes
that are not tendered or are tendered but not accepted will, following the
consummation of the Exchange Offer, continue to be subject to the existing re-
strictions upon transfer thereof and, upon consummation of the Exchange Offer,
certain registration rights under the Registration Rights Agreement will ter-
minate. In addition, any holder of Original Notes 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 re-
quired to comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any resale transactions. Each holder of
the Original Notes who wishes to exchange the Original Notes for Exchange
Notes in the Exchange Offer will be required to represent in the Letter of
Transmittal that at the time of the consummation of the Exchange Offer:
 
  . it is not an affiliate of the Issuers or Insight Ohio or, if it is such
    an affiliate, such holder will comply with the registration and prospec-
    tus delivery requirements of the Securities Act to the extent applicable;
 
  . the Exchange Notes to be received by it are being acquired in the ordi-
    nary course of its business; and
 
  . it has no arrangement or understanding with any person to participate in
    the distribution of the Original or Exchange Notes within the meaning of
    the Securities Act.
 
  Each broker-dealer (a "Participating Broker-Dealer") that receives Exchange
Notes for its own account in exchange for Original Notes, where such Original
Notes were acquired by such Participating Broker-Dealer as a result of market-
making activities or other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. See
"Plan of Distribution." To the extent that Original Notes are tendered and ac-
cepted in the Exchange Offer, the trading market for untendered and tendered
but unaccepted Original Notes could be adversely affected. See "The Exchange
Offer."

this Prospectus, including the timing, financing, strategies and effects of
such transactions, are forward-looking statements. Although the Issuers believe
that the expectations reflected in such forward-looking statements are reason-
able, they can give no assurance that such expectations will prove to have been
correct. Important factors that could cause actual results to differ materially
from expectations are disclosed in this Prospectus, including, without limita-
tion, in conjunction with the forward-looking statements in this Prospectus
and/or under "Risk Factors." The Issuers do not intend to update these forward-
looking statements.

                                USE OF PROCEEDS
 
  The Exchange Offer is intended to satisfy certain of the Issuers'
obligations under the Registration Rights Agreement. The Issuers will not
receive any cash proceeds from the issuance of the Exchange Notes in the
Exchange Offer.
 
  The private offering of the Original Notes (the "Original Notes Offering")
was part of the Financing Plan, which was implemented to facilitate the
organization of Insight Ohio, the acquisition of the System by Insight Ohio
and to provide for the System's liquidity and operational and financial
flexibility. Pursuant to the Financing Plan:
 
  . Coaxial contributed to Insight Ohio substantially all of the assets
    comprising the System for which Coaxial received a 25% non-voting common
    membership interest in Insight Ohio as well as the Preferred Interests in
    Insight Ohio (such Preferred Interests will provide for distributions to
    Coaxial, which will be used (directly and indirectly) to pay interest and
    principal on the Notes and the Discount Notes, subject to certain
    financial covenants and other conditions expected to be set forth in the
    Senior Credit Facility);
 
  . Insight contributed $10.0 million in cash to Insight Ohio for which it
    received a 75% non-voting common membership interest in Insight Ohio;
 
  . Coaxial and Phoenix effected the Original Notes Offering;
 
  . Coaxial LLC and Coaxial Financing Corp. effected the private offering of
    the Discount Notes (the "Discount Notes Offering"); and
 
  . a portion of the existing indebtedness of the Issuers and certain of
    their affiliates, including settlement of related party balances, was
    repaid and the balance was purchased.
 
  The gross proceeds received by the Issuers from the Original Notes Offering
were $140.0 million. The gross proceeds received by Coaxial LLC and Coaxial
Financing Corp. (together, the "Discount Notes Issuers") from the Discount
Notes Offering were approximately $30.0 million. The net proceeds from such
private offerings (approximately $160.9 million) and the $10.0 million cash
contribution from Insight was used for the purchase and repayment of
outstanding indebtedness, working capital and deferred compensation and
severance payments. Prior to October 1998, Insight Ohio is expected to enter
into the Senior Credit Facility for the purpose of financing its future
working capital requirements, including the upgrade of the System's cable
plant and the introduction of new video services. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources" and "Description of Certain Indebtedness--Senior Credit
Facility."

    SELECTED HISTORICAL AND COMBINED PRO FORMA FINANCIAL AND OPERATING DATA
 
  The following tables present selected historical financial data for Coaxial
and Phoenix as of and for the five years ended December 31, 1997, and
unaudited selected historical financial data as of and for the six months
ended June 30, 1997 and 1998. The statement of operations data for the periods
ended December 31, 1997, 1996, and 1995 and balance sheet data as of December
31, 1997 and 1996 have been derived from the audited financial statements of
Coaxial and Phoenix. The financial data of all other periods are derived from
the unaudited financial statements of Coaxial and Phoenix included elsewhere
in this Prospectus. In the opinion of management, such unaudited financial
statements have been prepared on the same basis as the audited financial
statements and include all normal and recurring adjustments and accruals
necessary for a fair presentation of such information. Financial results for
the six months ended June 30, 1998 are not necessarily indicative of the
results that may be expected for the full year.
 
  In addition, the following tables present unaudited combined selected pro
forma financial data for Coaxial and Phoenix for the year ended December 31,
1997 and as of and for the six months ended June 30, 1998, as adjusted to give
pro forma effect to the Financing Plan and certain other adjustments, in the
case of the statement of operations and other financial and operating data as
if they had occurred on the first day of the respective periods, and in the
case of balance sheet data as if they had occurred as of such date.
 
  The unaudited combined selected pro forma financial data have been prepared
by the management of Coaxial and Phoenix based upon their historical financial
statements and do not purport to represent what the results of operations or
financial condition of Coaxial and Phoenix would have actually been or what
operations in any future period would be if the transactions that give rise to
the pro forma adjustments had occurred on the dates assumed. Management
believes that the combined pro forma data is a meaningful presentation because
Phoenix has no operations for the presented periods, and the ability of
Coaxial and Phoenix to satisfy debt and other obligations is dependent upon
cash flow from the System. The following information is qualified by reference
to and should be read in conjunction with "Capitalization," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Pro Forma Financial Statements" and the financial statements and notes
thereto included elsewhere in this Prospectus.

                  NOTES TO SELECTED HISTORICAL AND PRO FORMA
                         FINANCIAL AND OPERATING DATA
 
 (1) Represents EBITDA (as defined below in Note 3) plus home office expense
     for periods prior to the System Acquisition, and EBITDA plus management
     fees for periods after or which give effect to the System Acquisition.
     Management believes that System Cash Flow is a meaningful measure of
     performance because it is commonly used in the cable television industry
     to analyze and compare cable television companies on the basis of
     operating performance, leverage and liquidity. However, System Cash Flow
     is not intended to be a performance measure that should be regarded as an
     alternative to, or more meaningful than, either operating income or net
     income as an indicator of operating performance or cash flows as a
     measure of liquidity, as determined in accordance with generally accepted
     accounting principles. System Cash Flow, as computed by management, is
     not necessarily comparable to similarly titled amounts of other
     companies. See the financial statements, including the Statements of Cash
     Flows, included elsewhere in this Prospectus.
 
 (2) Represents results for the three months ended June 30 multiplied by four.
 
 (3) Represents net income before depreciation, amortization, interest
     expense, other expenses, and gain on settlement of limited partners.
     Management believes that EBITDA is a meaningful measure of performance
     because it is commonly used in the cable television industry to analyze
     and compare cable television companies on the basis of operating
     performance, leverage and liquidity. However, EBITDA is not intended to
     be a performance measure that should be regarded as an alternative to, or
     more meaningful than, either operating income or net income as an
     indicator of operating performance or cash flows as a measure of
     liquidity, as determined in accordance with generally accepted accounting
     principles. EBITDA, as computed by management, is not necessarily
     comparable to similarly titled amounts of other companies. See the
     financial statements, including the Statements of Cash Flows included
     elsewhere in this Prospectus.
 
 (4) Represents EBITDA plus launch fees, which are deferred and amortized over
     the applicable contract period for financial reporting purposes. Adjusted
     EBITDA for the six months ended June 30, 1998 and Annualized Adjusted
     EBITDA includes approximately $848,000 of launch fees.
 
 (5) For purposes of calculating the ratio of earnings to fixed charges,
     earnings include income (loss) before extraordinary items plus interest
     expense (which includes amortization of debt issuance costs). Fixed
     charges consist of interest expense incurred (including amortization of
     debt issuance costs) and the estimated interest component of rent expense
     (approximately one-third). For Phoenix, earnings were inadequate to cover
     fixed charges by $7.0 million, $7.2 million, $12.4 million, $12.5 million
     and $8.8 million for the years ended December 31, 1993, 1994, 1995, 1996
     and 1997, respectively, and by $5.8 million and $6.5 million for the six
     months ended June 30, 1997 and 1998, respectively.
 
 (6) Refers to estimates by management of the approximate number of dwelling
     units in a particular community that can be connected to the System.
 
 (7) A home with one or more television sets connected to a cable system is
     counted as one basic subscriber. Bulk accounts are included on an
     equivalent basic unit basis in which the total monthly bill for the
     account is divided by the basic monthly charge for a single outlet in the
     area.
 
 (8) Calculated as basic subscribers as a percentage of homes passed.
 
 (9) Includes only single channel services offered for a monthly fee per
     channel and does not include tiers of channels offered as a package for a
     single monthly fee. A subscriber may purchase more than one premium
     service, each of which is counted as a separate premium service unit.
 
(10) Calculated as premium service units as a percentage of basic subscribers.
 
(11) Represents revenues of the System during the respective period divided by
     the months in the period divided by the average number of basic
     subscribers (beginning of period plus end of period divided by two) for
     such respective period.

(13) Represents Annualized Adjusted EBITDA during the respective period divided
     by the average number of basic subscribers (beginning of period plus end
     of period divided by two) for such respective period.
 
(14) Management believes that the following adjustments to historical
     annualized EBITDA for the three months ended June 30, 1998 are relevant to
     evaluating the operating performance of the System. These annualized pro
     forma adjustments reflect: (i) programming rate savings from MediaOne;
     (ii) headcount reductions primarily due to duplication within the finance
     and accounting departments; (iii) elimination of rent expense due to the
     contribution of an office building to the System as part of the
     Contribution Agreement; (iv) elimination of home office expenses relating
     to Coaxial's owners; and (v) management fees to be paid to Insight.
     Management believes these adjustments to be reasonable. In addition,
     annualized pro forma adjusted EBITDA reflects a supplemental adjustment
     for launch fees for Fox News and Great American Country. The System has
     received launch fees in the past, and management believes it will continue
     to receive launch fees in the normal course of business.
 
    The following table reflects the effects of these items on historical
    annualized EBITDA:

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the financial
statements and related notes which are included elsewhere in this Prospectus.
This Prospectus contains certain forward-looking statements that involve risks
and uncertainties. Future results could differ materially from those discussed
in this Prospectus. Factors that could cause or contribute to such differences
include, but are not limited to, those set forth under "Risk Factors" and
elsewhere in this Prospectus.
 
ACQUISITION OF SYSTEM BY INSIGHT OHIO
 
  On August 21, 1998, as part of the Financing Plan, Coaxial contributed to
Insight Ohio substantially all of the assets comprising the System, and
Insight contributed to Insight Ohio $10.0 million in cash. As a result of the
Financing Plan, Insight and Coaxial own 75% and 25%, respectively, of the non-
voting common membership interests of Insight Ohio. Coaxial also owns the
Preferred Interests having distribution priorities which will provide for
distributions to Coaxial that will be used to pay interest and principal on
the Notes and to pay dividends to the Individual LLCs that will be used to pay
interest and principal on the Discount Notes. Distributions by Insight Ohio
will be subject to certain financial covenants and other conditions expected
to be set forth in the Senior Credit Facility. Phoenix has nominal assets.
Coaxial's principal assets are non-voting common membership interests and the
voting Preferred Interests in Insight Ohio. None of the Issuers conduct any
business. The Issuers are dependent upon the cash flow of Insight Ohio to meet
their obligations under the Notes. See "Risk Factors--Conditional Guarantees;
Structural Subordination" and "The System Acquisition."
 
  The following discussion relates to the historical operations of the System
for the periods indicated. Such historical information reflects the operation
and management of the System by Coaxial and does not reflect any changes in
the operation or management of the System that Insight intends to make and is
not necessarily indicative of the historical results that would have been
achieved had the System been managed and operated by Insight during all of the
periods with respect to which financial information is presented in this
Prospectus. The historical operating results of the System presented below do
not reflect the actual results of Coaxial as presented in the financial
statements of Coaxial appearing elsewhere in this Prospectus, which also
include operations unrelated to the System. As the Issuers' ability to service
the Notes is dependent upon cash generated from the operations of the System,
it is more meaningful to compare the historical results of the System, which
results appear in the financial statements under the heading "Central Ohio
Cable System Operating Unit" elsewhere in this Prospectus. See page F-1 in
this Prospectus.
 
OVERVIEW
 
  Revenues generated by the System are primarily attributable to monthly
subscription fees charged to basic subscribers for basic and premium cable
television programming services. Basic revenues consist of monthly
subscription fees for all services (other than premium programming) as well as
monthly charges for customer equipment rental. Premium revenues primarily
consist of monthly subscription fees for programming provided on a per channel
basis. In addition, other revenues are derived from installation and
reconnection fees charged to basic subscribers to commence or discontinue
service, pay-per-view charges, late payment fees, franchise fees, advertising
revenues and commissions related to the sale of goods by home shopping
services.
 
  System operating expenses consist of service and administration expenses,
home office expenses and depreciation and amortization. Service and
administration expenses include direct costs, such as fees paid to programming
suppliers, expenses related to copyright fees, bad debt expense, and franchise
and use fees. Programming fees have historically increased at rates in excess
of inflation due to increases in the number of programming services offered by
the System and improvements in the quality of programming. While it has been
 
                                      39
<PAGE>
 
difficult to pass these increases to subscribers in recent years because of
the necessity to meet promotional rates engendered by the introduction of a
competitive service, Management believes rates will stabilize and it will
again become possible to cover any increases in the costs of programming.
Service and administration expenses also include costs attributable to the
operation of the System, including wages and salaries and other expenses
related to plant operating activities, customer service operations, marketing,
billing, advertising sales, video production, finance and accounting, human
resources and other administrative functions.
 
  The System relies on Insight for all of its strategic, managerial, financial
and operational oversight and advice. Insight also coordinates and provides
advice with respect to programming arrangements, engineering in the areas of
routine maintenance, system improvements and new technologies. In exchange for
all such services provided to the System and subject to certain restrictions
contained in the covenants with respect to the Senior Credit Facility, the
Notes and the Discount Notes, Insight is entitled to receive management fees
of 3.0% of gross operating revenues of the System. Such management fee is
payable only after distributions have been made in respect of the Preferred
Interests and only to the extent that such payment would be permitted by an
exception to the restricted payments covenants of the Notes and the Discount
Notes as well as the proposed Senior Credit Facility. See "Description of the
Notes--Certain Covenants--Limitation on Restricted Payments" and "The System
Acquisition."
 
COMPETITIVE OVERVIEW
 
  In 1996, Ameritech, the telephone local exchange carrier for Columbus,
obtained a citywide cable television franchise for the City of Columbus.
Ameritech began offering cable television service in June 1996 and to date has
substantially built its entire citywide franchise, both in the System's
service area and in the Time Warner service area on the west side of Columbus.
The Time Warner system and the System service virtually distinct areas and
therefore do not compete with each other. The overbuild by Ameritech passes
approximately 71% of the homes passed by the System (approximately 120,000
homes), effectively allowing approximately 60,000 of the System's basic
subscribers to choose between Ameritech and the System. Ameritech has cable
television franchise applications pending in two surrounding communities
covering an additional 2,000 of the System's homes and 1,200 of the System's
subscribers.
 
  Management's strategy to compete with the overbuild has included the
following:
 
  . Management implemented technological upgrades in areas likely to be
    overbuilt by constructing additional fiber optic cable and creating new
    nodes. At the present time, the System has constructed 17 distinct
    "enhanced areas" encompassing all of the 60,000 overbuilt subscribers.
 
  . The effective bandwidth of each enhanced area was increased from 450 MHz
    to 490 MHz, allowing for more movies, music, news, live sports and
    exclusive programming such as TV Land and Central Ohio Sport! Television.
    This brought the standard and premium offerings very close to what
    Ameritech is able to provide on its newly constructed 750 MHz system.
 
  . The System developed a packaging and pricing strategy that it believes
    was seen as a value by customers, providing the System with a competitive
    advantage over Ameritech.
 
  . Marketing efforts were expanded in the enhanced areas by increasing the
    number of promotional video spots targeted specifically to the
    competitive area advertising the advantages of System service. Mail drops
    were increased to at least twice monthly in each enhanced area with a
    constantly changing series of promotional programs.
 
  The promotions offered to certain of the System's subscribers had a negative
impact on operating results. Management believes that the adverse impact of
its promotional activities will be reduced in the future as the promotions
began expiring in July 1998. Management believes that the System has been
effective in competing with Ameritech and maintaining its overall subscriber
base. Since the beginning of the overbuild in June 1996, the System's
subscriber base has increased from approximately 87,700 to approximately
91,100 as of June 30, 1998. In the overbuild area, the System currently serves
approximately 60,000 subscribers. The System's net loss in the overbuild area
has been limited to approximately 1,100 subscribers since Ameritech entered
the market as the System has increased penetration from 46.1% to 50.2%.

RESULTS OF OPERATIONS
 
 Six Months Ended June 30, 1998 Compared to Six Months Ended June 30, 1997
 
  Revenues for the six months ended June 30, 1998 were $23.8 million, compared
to $24.5 million for the six months ended June 30, 1997. Revenues from basic,
standard and premium services decreased by $1.1 million, or 5.5%, from $20.1
million for the 1997 period to $19.0 million for the 1998 period. This
reduction reflects promotional rates offered to certain subscribers in the last
half of 1997. As noted above, promotional activities were reduced at the
beginning of 1998 but will continue to affect revenues through much of 1998 as
the year-long promotion ends and customers are then charged the System's
standard rates. The reduction in revenues also reflects the approximately
14,000 additional subscribers which were subject to the competitive environment
in 1998, compared to the first six months of 1997. Other revenues increased
slightly from $1.0 million to $1.1 million. Advertising revenues increased from
$1.6 million to $1.9 million, or 18.8%.
 
  Service and administration expenses (including home office) rose to $15.4
million for the six months ended June 30, 1998, compared to $14.0 million for
the same period in 1997, an increase of $1.4 million, or 10.0%. Programming
expenses increased by 18.3%, from $6.0 million in 1997 to $7.1 million in 1998,
reflecting additional channels provided in the competitive areas (as discussed
above), an increase in subscribers and annual increases in programming rates.
Fees for basic and standard programming increased by $828,000, from $3.2
million in 1997 to $4.0 million in 1998, while premium services programming
costs increased by $300,000, from $1.9 million in 1997 to $2.2 million in 1998,
or 15.8%. Fees for pay-per-view programming services decreased by $60,000, or
10.8%, reflecting a drop in the number of special events available during 1998.
Other increases in operating expenses included sales and marketing expenses,
which increased by $121,000, or 25.0%, due primarily to initiation of a door-
to-door sales program and an increase in the number of promotional campaigns.
Technical operations increased $95,000 due primarily to increased installation
costs because of greater churn and increased underground locate charges due to
significant Ameritech construction activity early in the year. The System was
charged home office expenses that include costs incurred by the owners of
Coaxial and their direct employees relating to the System including salaries,
benefits, legal fees, travel and entertainment, accounting fees and other
office expenses. For the six months ended June 30, 1998, such expenses totaled
$731,000, an increase of $28,000, or 4.0%. Upon consummation of the System
Acquisition, Insight will provide management services to the System for which
it will receive a management fee.
 
  Depreciation relating to the System increased by $157,000, or 6.3%, due to
construction in late 1997 and early 1998 to enhance the System in overbuilt
areas. Amortization decreased by $240,000, or 91.8%, as franchising costs have
become fully amortized.
 
 Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
 
  Revenues for the year ended December 31, 1997 were $48.2 million, compared to
$50.4 million for the year ended December 31, 1996, a decrease of $2.2 million,
or 4.3%. Basic, standard and premium revenues accounted for nearly all of the
decrease, declining from $41.3 million in the 1996 period to $39.2 million in
the 1997 period, a decrease of $2.1 million, or 5.1%. This decline in revenue
reflects the full impact of the competitive environment for approximately
23,000 subscribers who were overbuilt in the last half of 1996, the addition of
approximately 23,000 subscribers to the overbuilt areas during 1997 and the
effect of a promotional campaign used to grow subscribers in the last half of
1997. The overall result of the rate reductions and promotional campaign was
alleviated by subscriber growth during 1997, from approximately 88,000 at the
end of 1996 to approximately 91,900 at year-end 1997, an increase of 4.4%.
Other revenue declined by $157,000, or 7.2%, to $2.0 million for 1997, from
$2.2 million in 1996, primarily due to installation revenues which were lower
due to promotional offerings. Advertising revenues increased to $3.4 million
for 1997, from $3.1 million in 1996, an increase of 9.7%.
 
  Service and administration expenses (including home office) rose to $28.9
million for the year ended December 31, 1997, compared to $26.9 million for the
same period in 1996, an increase of 7.4%. Fees for basic
 
                                       41
<PAGE>
 
and standard programming were $6.4 million in 1997, compared to $4.9 million
in 1996, an increase of 30.6%. The increase in programming costs reflected
additional services added in the competitive areas, subscriber growth and fee
increases. Home office expenses were $1.5 million in 1997, a decrease of
$200,000, or 11.8%, from $1.7 million in 1996. The reduction resulted
primarily from the elimination of salaries for shareholder officers. In
addition to programming costs, other expenses increased from $14.4 million in
1996 to $15.2 million in 1997, an increase of $800,000, or 5.6%. Of this
increase, $500,000 occurred in general and administrative and personnel
accounts due to increases in benefit costs, legal fees and office rent.
 
  Depreciation and amortization decreased by $100,000, or 1.8%, to a total of
$5.2 million in 1997.
 
 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  Revenues for the year ended December 31, 1996 were $50.4 million, compared
to $46.8 million for the year ended December 31, 1995, an increase of $3.6
million, or 7.7%. Basic, standard and premium revenues accounted for most of
the increase, rising $2.4 million, or 6.2%, from $38.9 million in 1995 to
$41.3 million in 1996, due to subscriber growth at a CAGR of approximately
2.3% and modest increases in rates. Pay-per-view revenues increased 33.3% to
$2.4 million in 1996, compared to $1.8 million in 1995. Advertising revenues
rose from $2.8 million in 1995 to $3.1 million in 1996, an increase of 10.7%,
and other revenue increased by $285,000 to $2.2 million in 1996.
 
  Service and administration expenses (including home office) rose to $26.9
million for the year ended December 31, 1996, an increase of $3.3 million, or
14.0%, compared to 1995. Programming fees accounted for 61.0% of this
increase, rising from $8.9 million in 1995 to $10.9 million in 1996, an
increase of 22.5%. In addition to programming costs, other expenses increased
by 8.8% in 1996. Sales and marketing expenses were $1.1 million in 1996, an
increase of 27.1%, primarily due to increased campaign costs associated with
the beginning of the competitive overbuild. Customer service and collection
expenses increased by 13.7% to $1.5 million in 1996 due to higher collection
costs and wage increases intended to decrease turnover. Personnel expenses
increased by 17.2% to $819,000 in 1996 due to higher benefits costs. Home
office expenses were $1.7 million in 1996 and 1995, respectively.
 
  Depreciation and amortization were $5.3 million in 1996, an increase of
$500,000, or 10.6%, compared to 1995, due primarily to increased construction
in 1996 associated with the competitive environment.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The cable television business is a capital intensive business that generally
requires financing for the upgrade, expansion and maintenance of the technical
infrastructure. The capital expenditures of Coaxial relating to the System
totaled $5.7 million, $6.0 million and $5.6 million for the years ended
December 31, 1995, 1996 and 1997, respectively, and $2.6 million for the six
months ended June 30, 1998. These expenditures were primarily for serving new
homes, the rebuild of cable plant, equipment purchases, the upgrade and
replacement of service vehicles and routine maintenance and replacement of
cable plant and related equipment. These capital expenditures were financed
through borrowings under a senior credit facility among Coaxial, Phoenix,
certain of their affiliated entities, The Chase Manhattan Bank, as agent, and
certain lenders (the "Chase Credit Facility") and cash flows from operations.
 
  Insight plans to further enhance the technical platform of the System by
upgrading the plant serving the majority of subscribers. The capability for
high-speed data transmission, impulse pay-per-view, digital tiers of service
and additional analog channels is intended to be provided by further
deployment of fiber optics, an increase in the bandwidth to 750 MHz,
activation of the reverse plant to allow two-way communications and the
installation of digital equipment.
 
                                      42
<PAGE>
 
  The Original Notes Offering was part of the Financing Plan implemented to
facilitate the organization of Insight Ohio, the acquisition of the System by
Insight Ohio and to provide for the System's liquidity and operational and
financial flexibility. Pursuant to the Financing Plan:
 
  . Coaxial contributed to Insight Ohio substantially all of the assets
    comprising the System for which Coaxial received a 25% non-voting common
    membership interest in Insight Ohio as well as the Preferred Interests in
    Insight Ohio, which provide for distributions to Coaxial that will be
    used to pay interest and principal on the Notes and to pay dividends to
    the Individual LLCs that will be used to pay interest and principal on
    the Discount Notes;
 
  . Insight contributed $10.0 million in cash to Insight Ohio for which it
    received a 75% non-voting common membership interest in Insight Ohio;
 
  . the Issuers effected the Original Offering;
 
  . the Discount Notes Issuers effected the Discount Notes Offering; and
 
  . a portion of the existing indebtedness of the Issuers and certain of
    their affiliates will be repaid and the balance will be purchased and
    restructured.
 
  Distributions by Insight Ohio are subject to certain financial covenants and
other conditions expected to be set forth in the Senior Credit Facility. See
"Use of Proceeds."
 
  Insight Ohio is expected to enter into the Senior Credit Facility prior to
October 1998 for the purpose of financing its future capital expenditures and
for working capital and general purposes, including the planned upgrade of the
System's technical capability, as discussed above. It is expected that the
Senior Credit Facility will be a six-year $25 million reducing revolving
credit facility. Upon consummation of the Financing Plan, there was
approximately $2.5 million available for Insight Ohio for working capital
purposes. It is expected that substantially all of the assets of Insight Ohio
will secure its performance under the Senior Credit Facility. See "Description
of Certain Indebtedness--Senior Credit Facility."
 
  The Issuers expect to make interest payments on the Notes from funds
distributed to Coaxial in respect of the Series A Preferred Interests in
Insight Ohio to the extent permitted under the terms of the Senior Credit
Facility. Insight Ohio accrues preferred dividends in respect of the Series A
Preferred Interests in amounts necessary to make payments under the Notes. See
"The System Acquisition," "Description of Governing Documents" and
"Description of Certain Indebtedness--Senior Credit Facility."
 
  Management anticipates that cash flows from operations, together with
amounts available under the Senior Credit Facility, will be sufficient to
finance the operating requirements of the System, debt service requirements,
distributions on the Preferred Interests and anticipated capital expenditures
for the foreseeable future.
 
INFLATION AND CHANGING PRICES
 
  The System's costs and expenses are subject to inflation and price
fluctuations. Although changes in costs can be passed through to subscribers,
such changes may be constrained by competition. Management does not expect
inflation to have a material effect on the System's results of operations.
 
YEAR 2000
 
  Management has performed a review of the Year 2000 preparedness relative to
the System, its accounting systems and customer billing arrangements.
Management believes that the System will not incur material costs in
connection with becoming Year 2000 compliant.

                                   BUSINESS
 
THE SYSTEM
 
  Insight Ohio was recently formed for the purpose of acquiring Coaxial's
cable television system in the Columbus, Ohio metropolitan area. As a result
of the Financing Plan, Insight owns 75% of the common membership interests of
Insight Ohio. Insight, one of the nation's top 20 cable television operators
(after its pending transactions), manages the operations of the System and has
effective control over its business. As a result of the Financing Plan,
Coaxial owns a 25% common membership interest in Insight Ohio.
 
  As of June 30, 1998, the System passed approximately 168,600 homes and
served approximately 91,100 basic subscribers in the eastern portion of the
City of Columbus and the surrounding suburban communities. Columbus, located
in the 34th largest designated market area ("DMA") in the United States, is
the capital of Ohio and home of The Ohio State University. In addition to the
state government and university, the Columbus economy is well diversified with
a significant presence of prominent companies such as The Limited, Merck,
Wendy's, Nationwide Insurance, Borden and Worthington Industries. The area's
strong economy provides for a well-paid employment base with an unemployment
rate of 2.9%. The average household income of the System's service area is
approximately $51,000 per year.
 
  Portions of the System operate in a competitive environment. Subscribers in
those areas have access to two wired cable television providers--the System
and Ameritech's cable subsidiary, Ameritech New Media--as well as DBS systems
and MMDS systems. The areas of the System served by two wireline operators
pass approximately 120,000 homes, representing 71% of the System's total homes
passed. Even in this competitive environment, the System's basic subscribers
increased from approximately 86,000 at the end of 1995, prior to Ameritech's
entry into the marketplace, to approximately 91,100 as of June 30, 1998, a
compound annual growth rate ("CAGR") of 2.3%.
 
  Offsetting some of the impact of competition, the System enjoys a high level
of population growth in the suburban communities east of Columbus. Over the
past three years, more than 14,400 homes passed have been added to the System
through new plant extensions, primarily in new housing developments. This
represents a 3.0% CAGR of homes passed for the System, which Management
believes is one of the highest levels in the cable television industry for a
major cable system.
 
  Insight expects in the near future to upgrade the technical capability of
the System by increasing its bandwidth to 750 MHz. Currently, the System has
approximately 800 miles of 490 MHz plant and approximately 1,700 miles of 468
MHz plant. There also are approximately 160 miles of fiber optic cable
deployed in the System. The increase in bandwidth will allow the System to
deliver new services such as digital cable, high-speed Internet connections,
two-way data, and other telecommunications services.
 
  The System has developed an award winning local-origination and production
team which has created a firm foundation for its position in the community as
a "good citizen." An impressive list of awards has further enhanced the
System's strong local presence, including:

THE MANAGER
 
  Insight is one of the top 20 multiple system operators ("MSOs") in the
United States (after its pending transactions). For the past five years,
Insight's largely suburban properties have resulted in average growth rates
for homes passed and subscribers of 4.8% and 5.9%, respectively, among the
fastest growth rates achieved in the industry. Insight was co-founded in 1985
by Sidney R. Knafel, Chairman of Insight, and Michael S. Willner, President
and Chief Executive Officer of Insight, both of whom have been active in the
cable business since the early 1970's. Kim D. Kelly joined Insight in 1990 as
Executive Vice President and Chief Financial Officer and recently was named
Chief Operating Officer. In addition to many years of conventional cable
television experience, Insight's management team has been intimately involved
in the development and deployment of full service telecommunications networks.
In 1989, through an affiliated entity, Insight Communications Company U.K.,
L.P., Insight entered the U.K. cable television market, where today modern
hybrid fiber-coaxial networks are deployed widely. Messrs. Knafel and Willner
remain on the board of NTL, Inc., the publicly traded successor to the Insight
U.K. affiliate and one of the three major cable television operators in the
competitive U.K. market with franchises covering over five million homes,
including pending acquisitions.
 
  A series of swaps, acquisitions and a joint venture have recently been
executed resulting in the current composition of Insight. The largest of these
transactions is the equal partnership between Insight and TeleCommunications,
Inc. ("TCI"), the largest MSO in the United States, which calls for, among
other things, the two companies to contribute most of their Indiana cable
systems into a joint venture which Insight will manage and control. Prior to
those transactions, as of June 30, 1998, Insight's systems were located in
seven states with approximately 65% of the subscribers clustered in Illinois
and Indiana. At the conclusion of all of its currently signed transactions,
Insight management estimates that Insight will own or manage cable television
systems with 525,000 subscribers in seven states with over 90% of the
subscribers clustered in Illinois, Indiana and Ohio.
 
  Insight's relationship with TCI provides Insight with a depth of knowledge
and understanding regarding principal and material issues and challenges
presently facing the cable television industry. Because of this relationship,
Insight has participated in TCI affiliate meetings to discuss important
industry topics such as digital technology, new generation converter designs,
cable modems, and most recently the impact of the proposed AT&T acquisition of
TCI both on TCI's affiliates and on the industry as a whole.
 
THE INSIGHT SYSTEMS
 
 The following table summarizes certain historical data relating to the cable
television systems operated by Insight during the five years ended December
31, 1997. Since there were no material acquisitions or divestitures of cable
systems during the period, the results depicted reflect only internal changes,
year-to-year:

  The table illustrates Insight's success in acquiring high-growth cable
television systems in growing markets. From 1993 to 1997, the CAGR for homes
passed and basic subscribers was 4.8% and 5.9%, respectively. During 1994,
when the effect of the re-regulation of the cable industry impacted the
financial statements of the companies, Insight's revenue-per-subscriber was
reduced by over 3%. However, unlike most of the industry, EBITDA still
increased by nearly 5%.
 
INSIGHT BUSINESS STRATEGY
 
  Two years ago, Insight initiated a strategic plan designed to augment its
core business of delivering multi-channel video. The strategy calls for:
 
  . the upgrade of plant to 750 MHz hybrid fiber-coaxial platforms from which
    to deploy new value-added services such as high-speed data access,
    digital video and telephony services;
 
  . the reconfiguration of existing systems in a series of swaps to achieve
    subscriber clusters with a strong market presence; and
 
  . an acquisition plan focused on markets with attractive demographics and a
    high ratio of subscribers to headends.
 
  The acquisition of the System by Insight Ohio is an integral part of
Insight's long-term business strategy. The System has a strong market presence
in a state capital and academic center with a diverse, growing economy. All of
the System's approximately 91,100 subscribers are served from a single headend
allowing for efficient capital deployment for new services.
 
INSIGHT'S SYSTEM OPERATING STRATEGY
 
  The System fits the profile of cable television systems that Insight seeks
to own and operate. The System is large enough to have a significant market
presence and all subscribers are serviced from one headend. In addition,
Columbus is geographically proximate to other Insight cable systems with a
subscriber universe having the type of demographic profile that Insight
believes will widely accept new telecommunications offerings. Insight intends
to aggressively implement its upgrade strategy in Columbus.
 
  During the first year after the System Acquisition, Management expects to
increase the System's channel capacity in order to broaden its core analog
service offerings. Management also expects to increase revenues as the System
upgrade is completed by adding new services such as digital cable, high-speed
modems and other newly developing telecommunications services. Insight already
has a national affiliation agreement with @Home to provide high-speed Internet
connections over its cable television system infrastructure. Management either
will extend that agreement to the System or will affiliate the System with
Time Warner's Road Runner Internet service which is presently available in
Time Warner's Columbus cable system.
 
  With respect to programming, Management believes it can effectively
repackage the channel offerings to more advantageously compete without
reducing revenue per subscriber. Management's strategy is to compete in the
marketplace with its exclusive local programming, higher quality local service
and increased new technology offerings as opposed to promotional discounts.
 
  Due to its relationship with MediaOne (formerly Continental Cablevision),
Insight will provide programming discounts to the System through November
1999. After such date, Insight believes that through its strategic alliances
with other major MSOs, utilizing programming cooperatives or through its own
purchasing power, it will be able to continue to obtain programming for the
System at a cost lower than that presently available to Coaxial. Management
also plans to implement additional cost savings measures, including specific
employee reductions.

OVERBUILD
 
  In 1996, Ameritech, the telephone local exchange carrier for Columbus,
obtained a citywide cable television franchise for the City of Columbus.
Ameritech began offering cable television service in June 1996 and to date has
substantially built its entire citywide franchise, both in the System's
service area and in the Time Warner service area on the west side of Columbus.
The Time Warner system and the System service virtually distinct areas and
therefore do not compete with each other. The overbuild by Ameritech passes
approximately 71% of the homes passed by the System (approximately 120,000
homes), effectively allowing approximately 60,000 of the System's basic
subscribers to choose between Ameritech and the System. Ameritech has cable
television franchise applications pending in two surrounding communities
covering an additional 2,000 of the System's homes and 1,200 of the System's
subscribers.
 
  Coaxial's strategy to compete with the overbuild has included the following:
 
  . selectively constructing fiber optic cable deeper into the overbuild area
    to create additional channel capacity;
 
  . adding more movies, music, news, live sports and exclusive programming
    such as TV Land and Central Ohio Sport! Television on the higher
    bandwidth;
 
  . decreasing the System's standard rate to be slightly below that offered
    by Ameritech;
 
  . repackaging the System's pay services and selectively using promotions;
 
  . significantly increasing the use of focused target marketing; and
 
  . stressing local customer service.
 
  The promotions offered to certain of the System's subscribers had a negative
impact on operating results. Management believes that the adverse impact of
its promotional activities will be reduced in the future as the promotions
began expiring in July 1998.
 
  Management believes that the System has been effective in competing with
Ameritech and maintaining its overall subscriber base. Since the beginning of
the overbuild in June 1996, the System's subscriber base has increased from
approximately 87,700 to approximately 91,100 as of June 30, 1998. In the
overbuild area, the System currently serves approximately 60,000 subscribers.
The System's net loss in the overbuild area has been limited to approximately
1,100 subscribers since Ameritech entered the market as the System has
increased penetration from 46.1% to 50.2%. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Competitive
Overview."
 
TECHNOLOGICAL DEVELOPMENTS
 
  Management believes that in order to achieve consistently high levels of
customer service, maintain a strong competitive posture and deploy important
new technologies, a robust technical platform needs to be maintained.
Presently the System is comprised of approximately 2,500 miles of plant
passing approximately 168,600 homes resulting in a density of 67 homes per
mile. Approximately 32% of the plant has been expanded to 490 MHz and
approximately 68% is built at 468 MHz. The System is 100% addressable, with
approximately 84% of the basic subscribers having addressable converters.
 
  The System's deployment of fiber optic cable began in 1989. Its use was
originally for two main purposes: to improve end-of-the-line performance and
to increase reach for service of areas as yet uncabled. In addition, the fiber
program created a redundant network allowing for automatic backup in case of
system failure. Presently, 72 nodes are active, allowing for narrow casting
and differentiation of channel lineups from the single headend.
 
  A direct result of this fiber-rich platform is an improvement in picture
quality, and the impact of System outages has been diminished because outages
impact much smaller areas (especially in terms of commercial power problems).
The System now has the capability to run four separate lineups from a single
headend and has the ability to narrow-cast in terms of cross-channel
advertisement and zone areas for commercial insertion. In
 
                                      47
<PAGE>
 
addition, this platform will allow for the roll out of future new revenue
streams such as high-speed data, Internet access and interactive services. A
self-healing ring is also in place that feeds the optical transition hub
building to prevent catastrophic failure in all associated areas. Internet
high-speed data services were launched in May 1998.
 
  Insight plans to further enhance the technical platform of the System by
upgrading the plant serving the majority of subscribers. The capability for
high-speed data transmission, impulse pay-per-view, digital tiers of service
and additional analog channels is intended to be provided by further
deployment of fiber optics, an increase in the bandwidth to 750 MHz,
activation of the reverse plant to allow two-way communications and the
installation of digital equipment.
 
  All of the System's basic subscribers currently have access to addressable
technology and approximately 84% have addressable converters in their homes.
Addressable technology enables the System to electronically control the cable
television services being delivered to the customer's home. As a result, the
System can electronically upgrade or downgrade services to a customer
immediately, from its customer service center, without the delay or expense
associated with dispatching a technician to the customer's home. Addressable
technology also reduces premium service theft, is an effective enforcement
tool in the collection of delinquent payments and enables the System to offer
pay-per-view services, including movies and special events.
 
  Management believes that active use of fiber optic technology as an
alternative to coaxial cable is expected to play a major role in expanding
channel capacity and improving the performance of the System. Fiber optic
strands are capable of carrying hundreds of video, data and voice channels
over extended distances without the extensive signal amplification typically
required for coaxial cable. The System will continue to deploy fiber optic
cable further reducing amplifier cascades while improving picture quality and
system reliability.
 
  Recently, high-speed cable modems and set-top boxes using digital
compression technology have become commercially viable. These developments
allow for the introduction of high-speed data services and Internet access and
will increase the programming services available to customers. Digital
compression technology provides for a significant expansion of channel
capacity with up to 12 digital channels to be carried in the bandwidth of one
analog channel. Insight has experimented with 3Com cable modems in its
Noblesville, Indiana system and plans to deploy a high-speed Internet service
in some systems before the end of 1998. Insight has a national affiliation
agreement with @Home, the largest high-speed Internet cable service.
Management intends to install two-way capability in the System rebuild and a
wide-spread rollout is planned for 1999.
 
MARKETING, PROGRAMMING AND RATES
 
 Marketing
 
  The System's marketing programs and campaigns are based upon offering a
variety of cable services creatively packaged and tailored to appeal to its
different markets and to segments within its markets. The System surveys its
customer base to ensure that it is meeting the demands of its customers and
stays abreast of its competition in order to effectively counter competitors'
promotional campaigns. The System uses a coordinated array of marketing
techniques to attract and retain customers and to increase premium service
penetration, including door-to-door and direct mail solicitation,
telemarketing, media advertising, local promotional events typically sponsored
by programming services and cross-channel promotion of new services and pay-
per-view. Using a skilled team of marketing professionals, the System has
competed by supporting an innovative variety of marketing activities,
including the following:
 
  Promotion. The System's marketing team functions as an in-house ad agency
handling graphic design, art direction, television scripting and radio
scripting at significant savings over outside agencies. Using state-of-the-art
software packages, the marketing team is able to produce direct mail, video,
print and collateral marketing materials in-house. In addition, sophisticated
in-house capabilities allow for the quick and inexpensive production of
promotional and competitive educational spots to air on any of 20 channels for
which the System has inserted
 
                                      48
<PAGE>
 
advertising spots. Management zones the System's service areas into two
regions: competitive and non-competitive. This zoning provides separate and
distinct channel line-ups to subscribers in the competitive and non-
competitive regions of the System. The System also has its CableData homes
passed database zoned similarly. This provides a significant advantage by
delivering a customized "competitive" message to only those subscribers in the
zoned competitive area. The System has run an average of 15,000 marketing
commercials per month, fully utilizing any unsold advertising spots.
 
  Telemarketing. The System's in-house telemarketing operation consists of an
eight-person team including a supervisor and an order-entry person. A Telecorp
predictive dialer is used which allows the telemarketing group to achieve
better sales calls results. The telemarketing group also collects customer
surveys and provides additional phone capacity to customer service
representatives during peak periods such as heavy media campaigns.
 
  Guide. The System produces a 200-page monthly programming guide. The guide
features extensive custom features including the cover, pay-per-view, sports
calendars, VCR+ Codes and a 16-page advertiser supported coupon section. The
guide also gives the System a vehicle to provide subscriber notifications and
any technical information that is traditionally delivered via more expensive
bill inserts or direct mail. It is also customized and zoned to competitive
and non-competitive areas. The guide is profitable with a 68% penetration.
 
  Market Analysis. The System employs a full-time marketing analyst and
utilizes a wide variety of software programs, including Paradox and Claritas
Prism Cluster Coding. This support function supplies analysis and reporting
capabilities not normally available within cable industry MIS operations that
are traditionally supported by billing systems. This type of market analysis
is particularly effective in tracking competitive activity and promotional
offers in the overbuild areas.
 
  Apartment Management. Approximately 32% of the System's subscribers reside
in apartment housing units or Multiple Dwelling Units ("MDUs"). Management
believes that in a competitive environment, the management of the MDU market
and the apartment owners will grow in importance. The apartment group provides
support for the entire MDU customer base. The group works with apartment
managers throughout the System to manage move-in and move-out lists in an
effort to maximize penetration within the market. It has developed strong
working relationships with key apartment owners and managers and is an active
member in The Greater Columbus Apartment Association. As of June 30, 1998, the
group had executed exclusive contracts with apartment complexes representing
26,000 of the System's homes passed, providing a significant competitive
advantage in the overbuilt market.
 
  Network Spot Sales. In addition to customer fees, the System derives a
modest amount of revenue from the sale of local spot advertising time on
locally originated and satellite-delivered programming. The advertising sales
operation currently inserts advertising spots on the following 20 channels:
A&E, BET, Comedy Central, CNN, Discovery, ESPN, ESPN-2, Fox Family Channel,
Fox Sports, Golf, Headline News, Home & Garden, Lifetime, MTV, Nickelodeon,
TBS, TNN, TNT, TV Land and USA. The System utilizes digital insertion
technology supplied by SeaChange Digital. As a result of the latest insertion
equipment and an experienced and talented advertising team, the System
generates approximately $36.00 of total advertising revenue per subscriber on
an annual basis, placing it near the top of the industry in spot sales
revenue.
 
  Home Shopping. The System also derives a modest amount of revenue from
affiliations with home shopping services (which offer merchandise for sale to
customers and compensate system operators with a percentage of their sales
receipts). Utilizing two full-time networks and one part-time network, the
System generated home shopping revenues of $3.95 per subscriber in 1997.
 
  Other Advertising Sales. The System has also developed a classified channel
designed both to attract new advertising clients as well as to create value-
added programs which enhance subscriber satisfaction. Among the System's
programming are several real estate programs, a career search program, leased
access and a membership marketing program called "Cable Saver" which offers
discounts at local merchants to subscribers,
 
                                      49
<PAGE>
 
thus helping subscribers partially offset their cable bills. The System
expects to generate approximately $7.30 per subscriber on an annual basis from
classifieds. When combined with network spot sales, the System's strong
advertising business affords it the top spot among MSOs when ranked by gross
advertising revenue per basic subscriber.
 
  Central Ohio Sport! Television. In early 1998, the System teamed up with the
local Time Warner cable system to develop a local sports programming package
under the brand "Sport!". This exclusive package is not available to
Ameritech's cable subscribers. "Sport!" features as its cornerstone 31 Ohio
State University games including women's basketball, men's ice hockey, women's
volleyball, men's baseball and the annual Spring Football Game. In addition
"Sport!" will offer 40 to 50 additional professional, collegiate and high
school sporting events on the same exclusive basis.
 
  Production. The System produces all of the local programming for Central
Ohio Sport! Television, as well as other events as varied as harness racing
and marching band competitions. The System has a state-of-the-art commercial
production facility, including a 1996 mobile production vehicle, electronic
field production ("EFP") equipment and an on-line edit suite. The combination
of the mobile truck, EFP equipment and the edit suite allow the vast majority
of commercial production work to be done in-house at significant cost savings
over outside production facilities.
 
  High Speed Internet Access. In May 1998, the System began offering high-
speed Internet access via asymmetrical (telephone return) cable modems under
the brand name Coaxial Express. The service is provided in a "turnkey" fashion
under an agreement with Frontier Global Center. Customers can download files
and information from the Internet at speeds up to 1.5 megabits per second, or
30 to 50 times faster than traditional dial up Internet access services.
Ameritech does not offer high speed Internet access in the System's service
area, providing the System with a competitive advantage in the Internet access
market.
 
 Programming
 
  The System has various contracts to obtain basic and premium programming for
the System from program suppliers whose compensation is typically based on a
fixed fee per customer. Due to its relationship with MediaOne (formerly
Continental Cablevision), Insight will provide programming discounts to the
System through November 1999. After such date, Insight believes that through
its strategic alliances with other major MSOs, utilizing programming
cooperatives or through its own purchasing power, it will be able to continue
to obtain programming for the System at a cost lower than that presently
available to Coaxial.
 
  Some program suppliers provide volume discount pricing structures or offer
marketing support to the System. The System's successful marketing of multiple
premium service packages emphasizing customer value enables the System to take
advantage of such cost incentives. The System's programming costs are expected
to increase in the future due to additional programming being provided to its
customers, increased costs to purchase programming, inflationary increases and
other factors affecting the cable television industry. The System also has
various retransmission consent arrangements with commercial broadcast stations
which generally expire in December 1999 and beyond. None of these consents
require payment of fees for carriage; however, the System has entered into
agreements with certain stations to carry satellite-delivered cable
programming which is affiliated with the network carried by those stations.
See "Legislation and Regulation."
 
  The System offers a "basic service tier," consisting of local television
channels (network and independent stations) available over-the-air, and local
public, governmental and educational access channels. The System offers, for a
monthly fee, an expanded basic tier of various satellite-delivered, non-
broadcast channels (such as CNN, MTV, USA, ESPN and TNT). In addition to these
services, the System provides premium services such as HBO, Cinemax, Showtime,
The Movie Channel and Starz!, which are combined in different formats to
appeal to the various segments of the viewing audience. These services are
satellite-delivered channels consisting principally of feature films, original
programming, live sports events, concerts and other special entertainment
features, usually presented without commercial interruption. Such premium
programming services are offered by
 
                                      50
<PAGE>
 
the System both on a per-channel basis and as part of premium service packages
designed to enhance customer value and to enable the System to take advantage
of programming agreements offering cost incentives based on premium service
unit growth. Subscribers may subscribe to one or more premium service units. A
"premium service unit" is a single premium service for which a subscriber must
pay an additional monthly fee in order to receive the service. Management
plans to upgrade the System using fiber optic technology, which will allow the
System to expand the number of multiplexed premium screens (additional
channels such as Showtime 2 and HBO Family) providing greater value for the
subscriber. The upgrade will also give the System the ability to use "tiered"
packaging strategies for marketing premium services and promoting niche
programming services. Management believes that this ability will increase
basic and premium penetration as well as revenue per basic subscriber. The
System also provides five pay-per-view services purchased from independent
suppliers such as Viewer's Choice and Showtime Event Television. These
services are satellite-delivered channels, consisting principally of feature
films, adult movies, live sporting events, concerts and other special events,
usually presented without commercial interruption. Such pay-per-view services
are offered by the System on a "per viewing" basis, with subscribers only
paying for programs which they select for viewing.
 
 Rates
 
  Monthly customer rates for services vary from market to market, primarily
according to the amount of programming provided. At June 30, 1998, the
System's stated monthly basic service rate for residential customers was
$11.47, the System's monthly expanded basic service rates for residential
customers ranged from $14.93 to $18.65, and per-channel premium service rates
(not including special promotions) ranged from $5.95 to $12.95 per service. At
June 30, 1998, because of System promotional offerings, the weighted average
revenue (including special promotions) for the System's monthly combined basic
and expanded basic service was approximately $25.00.
 
  A one-time installation fee, which the System may wholly or partially waive
during a promotional period, is charged to new customers. The System charges
monthly fees for converters and remote control devices. The System also
charges administrative fees for delinquent payments for service. Customers are
free to discontinue service at any time without additional charge and may be
charged a reconnection fee to resume service. Commercial customers, such as
hotels, motels and hospitals, are charged negotiated monthly fees and a non-
recurring fee for the installation of service. Multiple dwelling unit accounts
may be offered a bulk rate in exchange for single-point billing and basic
service to all units.
 
  On February 11, 1997, a Petition for Determination of Effective Competition
filed by Coaxial challenging the certification of the City of Columbus was
granted by the FCC. This petition effectively revoked the City of Columbus'
right to regulate the System's basic cable and equipment rates.
 
EMPLOYEES
 
  As of June 30, 1998, the System employed approximately 200 full-time
equivalent employees, none of whom are represented by a union or covered by a
collective bargaining agreement. Management believes that its relations with
its employees are good. Approximately 50% of the full-time employees have
tenure of five years or longer. Although the Columbus area has relatively low
unemployment and competition in hiring is intense, Management believes that it
will continue to be successful in attracting and retaining highly qualified
employees and maintaining good working relationships with its current
employees.
 
PROPERTIES
 
  The System's principal physical assets consist of cable television operating
plant and equipment, including signal receiving, encoding and decoding
devices, headend and distribution systems and customer house drop equipment
for its cable television systems. The signal receiving apparatus includes a
tower, antenna, ancillary electronic equipment and earth stations for
reception of satellite signals. The headend, consisting of associated
electronic equipment necessary for the reception, amplification and modulation
of signals, is located near the
 
                                      51
<PAGE>
 
receiving devices. Most basic subscribers of the System utilize converters
that can be addressed by sending coded signals from the headend facility over
the cable network. See "--Technological Developments" above. The System's
distribution system consists primarily of coaxial and fiber optic cables and
related electronic equipment.
 
  The System owns parcels of real property for signal reception sites (one
antenna tower and one headend). The System also leases one small office and
one hub location. Management believes that its properties, both owned and
leased, are in suitable condition adequate for the System's operations.
 
  The System's cables generally are attached to utility poles under pole
rental agreements with local public utilities, although in some areas the
distribution cable is buried in underground ducts or trenches. The physical
components of the System require periodic upgrading to improve system
performance and capacity.
 
CUSTOMER SERVICE AND COMMUNITY RELATIONS
 
  The System is dedicated to quality customer service. Plans to make
significant system improvements are designed in part to strengthen customer
service through greater system reliability and the introduction of new
services. Management seeks a high level of customer satisfaction by also
employing a well-trained staff of customer service representatives and
experienced field technicians.
 
  Overall, the System employs 54 customer service representatives, an average
of one for every 1,685 subscribers, who answer phone calls and handle walk-in
traffic. The System utilizes an automated response unit system to track and
monitor subscriber calls, which allows customers to perform common functions
such as checking account balances, recent payments or scheduled appointments
using a touch-tone phone, without talking to a customer service
representative. Customers can also use the automated response unit system to
instantly upgrade premium services or order pay-per-view movies and events, as
well as report service problems. All newly hired customer service
representatives and technicians are trained in-house. Programmers and vendors
provide training and product updates via representatives who visit the System
office on a continual basis. Technicians are on call 24 hours per day, 365
days per year. All on-call technicians are equipped with pagers and two-way
radios. During the work day, technicians communicate with the System office
via business radios. The majority of re-connects and new connects or drop
replacements are performed by in-house personnel. All disconnects are
performed in-house.
 
  In addition, the System is dedicated to fostering strong community relations
in the communities served by the System. The System supports local charities
and community causes through staged events and promotional campaigns,
including Children's Hospital Miracle Network Telethon, the Penny-A-Day for
Children Program, strong United Way support and Red Cross Blood Drive
donations. The System also installs and provides free cable television service
and Internet access to public schools, government buildings and not-for-profit
hospitals in its franchise areas. Management believes that its relations with
the communities in which the System operates are generally excellent.
 
FRANCHISES
 
  Cable television systems are generally operated under non-exclusive
franchises granted by local governmental authorities. These franchises
typically contain many conditions, such as:
 
  . time limitations on commencement and completion of construction;
 
  . conditions of service, including number of channels, types of programming
    and the provision of free service to schools and certain other public
    institutions; and
 
  . the maintenance of insurance and indemnity bonds.
 
  The provisions of local franchises are subject to federal regulation under
the Communications Act. See "Legislation and Regulation."
 
 
                                      52
<PAGE>
 
  The System provides cable television service to residents of 41 governmental
jurisdictions. Within each of these governmental jurisdictions, the System
operates under authority granted by the local community or the State of Ohio.
Actual franchise agreements are maintained with the 28 jurisdictions that
possess the legal basis to grant such franchises consistent with federal and
state law. These franchises, which are non-exclusive, provide for the payment
of fees to the issuing authority. In the System, such franchise fees are
passed through directly to the customers. The Cable Acts prohibit franchising
authorities from imposing franchise fees in excess of 5% of gross revenue and
also permit the cable television system operator to seek renegotiation and
modification of franchise requirements if warranted by changed circumstances.
See "Legislation and Regulation."
 
  The majority of the System's basic subscribers are in governmental
jurisdictions that require a franchise. The table below groups all of the
System's governmental jurisdictions by date of expiration of the authority to
operate and presents the approximate number and percentage of basic
subscribers for each group as of April 22, 1998.

  The Cable Acts provide, among other things, for an orderly franchise renewal
process in which franchise renewal will not be unreasonably withheld or, if
renewal is denied and the franchising authority acquires ownership of the
system or effects a transfer of the system to another person, the operator
generally is entitled to the "fair market value" for the system covered by
such franchise. In addition, the Cable Acts established comprehensive renewal
procedures which require that an incumbent franchisee's renewal application be
assessed on its own merits and not as part of a comparative process with
competing applications. See "Legislation and Regulation."
 
  Management believes that it generally has good relationships with its
franchising communities. The System has never had a franchise revoked or
failed to have a franchise renewed. In addition, all of the franchises of the
System eligible for renewal have been renewed or extended at or prior to their
stated expirations, and no franchise community has refused to consent to a
franchise transfer to the System.
 
THE CABLE TELEVISION INDUSTRY
 
  The cable television industry developed in the United States in the late
1940's and early 1950's in response to the needs of residents in predominantly
rural and mountainous areas of the country where the quality of off-air
television reception was inadequate due to factors such as topography and
remoteness from television broadcast towers. In the late 1960's, cable
television systems also developed in small and medium-sized cities and
suburban areas that had a limited availability of clear off-air television
station signals. All of these markets are regarded within the cable industry
as "classic" cable television station markets. In more recent years, cable
television systems have been constructed in large urban cities and nearby
suburban areas, where good off-air reception from multiple television stations
usually is already available, in order to provide the numerous, satellite-
delivered channels carried by cable television systems which are not otherwise
available via broadcast television reception.
 
  A cable television system receives television, radio and data signals that
are transmitted to the system's headend site by means of off-air antennas,
microwave relay systems and satellite earth stations. These signals are then
modulated, amplified and distributed, primarily through coaxial, and in some
instances, fiber optic cable, to customers who pay a fee for this service.
Cable television systems may also originate their own television programming
and other information services for distribution through the system. Cable
television systems generally are constructed and operated pursuant to non-
exclusive franchises or similar licenses granted by local governmental
authorities for a specified term of years, generally for extended periods of
up to 15 years.
 
                                      53
<PAGE>
 
  Cable television systems offer customers various levels (or "tiers") of
cable television services consisting of:
 
  . off-air television signals of local network, independent and educational
    stations;
 
  . various satellite-delivered, non-broadcast channels (such as CNN, MTV,
    USA Network, ESPN and TNT);
 
  . certain programming originated locally by the cable television system
    (such as public, governmental and educational access programs); and
 
  . informational displays featuring news, weather, stock market and
    financial reports and public service announcements.
 
  For an extra monthly charge, cable television systems also offer premium
television services to their customers. These services (such as Home Box
Office, Showtime and regional sports networks) are satellite-delivered
channels consisting principally of feature films, live sports events, concerts
and other special entertainment features, usually presented without commercial
interruption.
 
  A customer generally pays an initial installation charge and fixed monthly
fees for basic and premium television services and for other services (such as
the rental of converters and remote control devices). Such monthly service
fees constitute the primary source of revenue for cable television operators.
In addition to customer revenue from these services, cable television
operators generate revenue from additional fees paid by customers for pay-per-
view programming of movies and special events and from the sale of available
advertising spots on advertiser-supported programming. Cable television
operators frequently also offer to their customers home shopping services,
which pay the systems a share of revenue from sales of products in the
systems' service areas. See "--Marketing, Programming and Rates" above.
 
COMPETITION
 
  The major source of competition for the System is Ameritech. Ameritech has
overbuilt approximately 120,000 homes passed in the System's service areas, or
approximately 71% of the total homes in the service territory as of June 30,
1998. See "--Overbuild" above and "Risk Factors--Significant Competition in
the Cable Television Industry; Overbuilds."
 
  Cable television systems face competition from alternative methods of
receiving and distributing television signals and from other sources of news,
information and entertainment such as off-air television broadcast
programming, newspapers, movie theaters, live sporting events, interactive
online computer services and home video products, including videotape cassette
recorders. The extent to which a cable television system is competitive
depends, in part, upon that system's ability to provide, at a reasonable price
to customers, a greater variety of programming and other communications
services than those which are available off-air or through other alternative
delivery sources and upon superior technical performance and customer service.
 
  Cable television systems generally operate pursuant to franchises granted on
a non-exclusive basis. The 1992 Cable Act prohibits franchising authorities
from unreasonably denying requests for additional franchises and permits
franchising authorities to operate cable television systems. See "Legislation
and Regulation." Well-financed businesses from outside the cable television
industry (such as the public utilities that own the poles to which cable is
attached) may become competitors for franchises or providers of competing
services. Competition from other video service providers exists in areas
served by the System. In a number of the franchise areas served by the System,
the System faces direct competition from other franchised cable television
operators. There can be no assurance, however, that additional cable
television systems will not be constructed in other franchise areas of the
System.
 
  Cable television operators also face competition from private satellite
master antenna television ("SMATV") systems that serve condominiums, apartment
and office complexes and private residential developments. SMATV systems offer
both improved reception of local television stations and many of the same
satellite-delivered program services offered by franchised cable television
systems. SMATV operators often enter
 
                                      54
<PAGE>
 
into exclusive agreements with building owners or homeowners associations,
although some states have enacted laws that authorize franchised cable
television operators access to such private complexes. These laws have been
challenged in the courts with varying results. In addition, some companies are
developing and/or offering to these private residential and commercial
developments packages of telephony, data and video services. Under the 1996
Telecom Act, SMATV systems can interconnect non-commonly owned buildings
without having to comply with local, state and federal regulatory requirements
that are imposed on cable television systems providing similar services, as
long as they do not use public rights-of-way. For instance, while a franchised
cable television system typically is obligated to extend service to all areas
of a community regardless of population density or economic risk, a SMATV
system may confine its operation to small areas that are easy to serve and are
more likely to be profitable. The System passes over 300 MDU complexes within
its service territory and currently has entry agreements, either exclusive or
non-exclusive, with complexes totaling approximately 60,000 MDUs. The System
currently provides programming to over 32,000 of these MDUs, or 54.1% of the
total MDUs passed. The ability of the System to compete for customers in
residential and commercial developments served by SMATV operators is
uncertain.
 
  The FCC has recently allocated a sizable amount of spectrum in the 27 to 31
GHz band for use by a new wireless service, Local Multipoint Distribution
Service ("LMDS"), which, among other uses, can deliver over 100 channels of
programming directly to consumers' homes. The FCC completed an auction of this
spectrum to the public in March 1998, in which the participation of cable
television operators and local telephone companies was restricted. The extent
to which the winning licensees in this service will use this spectrum in
particular regions of the country to deliver multichannel video programming
and other services to subscribers, and therefore provide competition to
franchised cable television systems, is uncertain at this time.
 
  Individuals presently have the option to purchase earth stations, which
allow the direct reception of satellite-delivered broadcast and non-broadcast
program services formerly available only to cable television subscribers. Most
satellite-distributed program signals are electronically scrambled so as to
permit reception only with authorized decoding equipment for which the
consumer must pay a fee. The 1992 Cable Act enhances the right of satellite
distributors and other competitors to purchase non-broadcast satellite-
delivered programming. The fastest growing method of satellite distribution is
by high-powered direct broadcast satellites ("DBS") utilizing video
compression technology. This technology has the capability of providing more
than 100 channels of programming over a single high-powered DBS satellite with
significantly higher capacity available if multiple satellites are placed in
the same orbital position. DBS service can be received virtually anywhere in
the United States through the installation of a small rooftop or side-mounted
antenna. DBS service is presently being heavily marketed on a nationwide basis
by three service providers. The 1996 Telecom Act and FCC regulations preempt
certain local restrictions on the location and use of DBS and other satellite
receiver dishes.
 
  DBS systems currently have certain advantages over cable television systems
with respect to programming and digital quality, as well as disadvantages that
include high upfront costs and a lack of local programming, service and
equipment distribution. One DBS provider, EchoStar, has announced plans to
offer some local signals in a limited number of markets. A review by the U.S.
Copyright Office is underway to determine if such offerings are permissible
under the copyright law. In addition, legislation has been introduced in
Congress to include carriage of local signals by DBS providers under the
copyright law. The ability of DBS to deliver local signals would eliminate a
significant advantage that cable television operators currently have over DBS
providers. The System will magnify its competitive service price points and
seek to maintain programming parity with DBS by selectively increasing channel
capacities of the System and introducing new premium channels, pay-per-view
and other services. Management estimates that there are approximately 5,700
DBS subscribers in its service area. Management believes that DBS erosion will
be minimal due to the marketing department's ability to properly educate
subscribers regarding pricing and packaging and offering high value-added
channel line-ups.
 
  Cable television systems also compete with wireless program distribution
services such as MMDS, which uses low-power microwave frequencies to transmit
video programming over the air to customers. Wireless distribution services
generally provide many of the programming services provided by cable
television systems, and digital compression technology is likely to increase
significantly the channel capacity of their systems.
 
                                      55
<PAGE>
 
MMDS service requires unobstructed "line of sight" transmission paths. In the
majority of the System's franchise service areas, prohibitive topography and
"line of sight" access have and are likely to continue to limit competition
from MMDS systems. Moreover, in the majority of the System's franchise areas
MMDS operators face significant barriers to growth since the lower population
densities make these areas less attractive. Management is not aware of any
significant MMDS operation currently within its cable television franchise
service areas. American Telecasting Inc. ("ATI") is an MMDS operator providing
service in the Columbus area and covering most of the System's service areas.
The System has run numerous competitive ad campaigns educating consumers
regarding the shortfalls of the ATI product, such as the limited number of
channels, the massive antennae required and service issues. Management
estimates that ATI has built a subscriber base of less than 500 subscribers in
the System's service areas.
 
  Other new technologies, including Internet-based services, may become
competitive with services that cable television systems can offer. The 1996
Telecom Act directed the FCC to establish, and the FCC has adopted,
regulations and policies for the issuance of licenses for digital television
("DTV") to incumbent television broadcast licensees. DTV is expected to
deliver high definition television pictures, multiple digital-quality program
streams, as well as CD-quality audio programming and advanced digital
services, such as data transfer or subscription video. The FCC also has
authorized television broadcast stations to transmit textual and graphic
information useful both to consumers and businesses. The FCC also permits
commercial and noncommercial FM stations to use their subcarrier frequencies
to provide nonbroadcast services including data transmissions. The FCC
established an over-the-air Interactive Video and Data Service that will
permit two-way interaction with commercial and educational programming along
with informational and data services. LECs and other common carriers provide
facilities for the transmission and distribution to homes and businesses of
video services, including interactive computer-based services like the
Internet, data and other nonvideo services.
 
  The 1996 Telecom Act provides that registered utility holding companies and
subsidiaries may provide telecommunications services (including cable
television) notwithstanding the Public Utilities Holding Company Act of 1935,
as amended. Electric utilities must establish separate subsidiaries known as
"exempt telecommunications companies" and must apply to the FCC for operating
authority. Due to their financial resources, electric utilities could be
formidable competitors to traditional cable television systems.
 
  Advances in communications technology as well as changes in the marketplace
and the regulatory and legislative environments are constantly occurring.
Thus, it is not possible to predict the effect that ongoing or future
developments might have on the cable industry or on the operations of the
System.

                          LEGISLATION AND REGULATION
 
  The cable television industry is regulated by the FCC, some state
governments and the applicable local governments. In addition, various
legislative and regulatory proposals under consideration from time to time by
Congress and various federal agencies have in the past, and may in the future,
materially affect the System and the cable television industry. The following
is a summary of federal laws and regulations materially affecting the growth
and operation of the cable television industry and a description of certain
state and local laws. Management believes that the regulation of its industry
remains a matter of interest to Congress, the FCC and other regulatory
authorities. There can be no assurance as to what, if any, future actions such
legislative and regulatory authorities may take or the effect thereof on the
System.
 
FEDERAL LEGISLATION
 
  The principal federal statute governing the cable television industry is the
Communications Act. As it affects the cable television industry, the
Communications Act has been significantly amended on three occasions, by the
1984 Cable Act, the 1992 Cable Act and the 1996 Telecom Act. The 1996 Telecom
Act altered the regulatory structure governing the nation's telecommunications
providers. It removed barriers to competition in both the cable television
market and the local telephone market. Among other things, it also reduced the
scope of cable rate regulation. In addition, the 1996 Telecom Act required the
FCC to undertake a host of rulemakings to implement the 1996 Telecom Act, the
final outcome of which cannot yet be determined.
 
FEDERAL REGULATION
 
  The FCC, the principal federal regulatory agency with jurisdiction over
cable television, has adopted regulations covering such areas as cross-
ownership between cable television systems and other communications
businesses, carriage of television broadcast programming, cable rates,
consumer protection and customer service, leased access, indecent programming,
programmer access to cable television systems, programming agreements,
technical standards, consumer electronics equipment compatibility, ownership
of home wiring, program exclusivity, equal employment opportunity, consumer
education and lockbox enforcement, origination cablecasting and sponsorship
identification, children's programming, signal leakage and frequency use,
maintenance of various records, and antenna structure notification, marking
and lighting. The FCC has the authority to enforce these regulations through
the imposition of substantial fines, the issuance of cease and desist orders
and/or the imposition of other administrative sanctions, such as the
revocation of FCC licenses needed to operate certain transmission facilities
often used in connection with cable operations. A brief summary of certain of
these federal regulations as adopted to date follows.
 
 Rate Regulation
 
  The 1984 Cable Act codified existing FCC preemption of rate regulation for
premium channels and optional nonbasic program tiers. The 1984 Cable Act also
deregulated basic cable rates for cable television systems determined by the
FCC to be subject to effective competition. The 1992 Cable Act substantially
changed the previous statutory and FCC rate regulation standards. The 1992
Cable Act replaced the FCC's old standard for determining effective
competition, under which most cable television systems were not subject to
rate regulation, with a statutory provision that resulted in nearly all cable
television systems becoming subject to rate regulation of basic service. The
1996 Telecom Act expands the definition of effective competition to cover
situations where a local telephone company or its affiliate, or any
multichannel video provider using telephone company facilities, offers
comparable video service by any means except DBS. Satisfaction of this test
deregulates both basic and nonbasic tiers. Additionally, the 1992 Cable Act
required the FCC to adopt a formula for franchising authorities to assure that
basic cable rates are reasonable; allowed the FCC to review rates for cable
programming service tiers ("CPST") (other than per-channel or per-program
services) in response to complaints filed by franchising authorities and/or
cable customers; prohibited cable television systems from requiring basic
subscribers to purchase service tiers above basic service in order to purchase
premium services if the system is technically
 
                                      57
<PAGE>
 
capable of doing so; required the FCC to adopt regulations to establish, on
the basis of actual costs, the price for installation of cable service, remote
controls, converter boxes and additional outlets; and allowed the FCC to
impose restrictions on the retiering and rearrangement of cable services under
certain limited circumstances. The 1996 Telecom Act limits the class of
complainants regarding CPST rates to franchising authorities only, after first
receiving two rate complaints from local basic subscribers, and ends FCC
regulation of CPST rates immediately for small systems owned by small cable
operators and on March 31, 1999 for all other cable television systems. The
System is not a "small cable operator" under the 1996 Telecom Act.
 
  The FCC's implementing regulations contain standards for the regulation of
basic service and CPST rates (other than per-channel or per-program services).
Local franchising authorities and the FCC, respectively, are empowered to
order a reduction of existing rates which exceed the maximum permitted level
for either basic and CPST services and associated equipment, and refunds can
be required. The FCC adopted a benchmark price cap system for measuring the
reasonableness of existing basic service and CPST rates. Alternatively, cable
operators have the opportunity to make cost-of-service showings which, in some
cases, may justify rates above the applicable benchmarks. The rules also
require that charges for cable-related equipment (e.g., converter boxes and
remote control devices) and installation services be unbundled from the
provision of cable service and based upon actual costs plus a reasonable
profit. The regulations also provide that future rate increases may not exceed
an inflation-indexed amount, plus increases in certain costs beyond the cable
operator's control, such as taxes, franchise fees and increased programming
costs. Cost-based adjustments to these capped rates can also be made in the
event a cable television operator adds or deletes channels. In addition, new
product tiers consisting of services new to the cable television system can be
created free of rate regulation as long as certain conditions are met, such as
not moving services from existing tiers to the new tier. There is also a
streamlined cost-of-service methodology available to justify a rate increase
on basic and regulated CPST tiers for "significant" system rebuilds or
upgrades.
 
  As a further alternative, in 1995 the FCC adopted a simplified cost-of-
service methodology which can be used by "small cable systems" owned by "small
cable companies" (the "small system rules"). A "small system" is defined as a
cable television system which has, on a headend basis, 15,000 or fewer basic
subscribers. A "small cable company" is defined as an entity serving a total
of 400,000 or fewer basic subscribers that is not affiliated with a larger
cable television company (i.e., a larger cable television company does not own
more than a 20 percent equity share or exercise de jure control). This small
system rate-setting methodology almost always results in rates which exceed
those produced by the cost-of-service rules applicable to larger cable
television operators. Once the initial rates are set they can be adjusted
periodically for inflation and external cost changes as described above. When
an eligible "small system" grows larger than 15,000 basic subscribers, it can
maintain its then current rates but it cannot increase its rates in the normal
course until an increase would be warranted under the rules applicable to
systems that have more than 15,000 subscribers. When a "small cable company"
grows larger than 400,000 basic subscribers, the qualified systems it then
owns will not lose their small system eligibility. If a small cable company
sells a qualified system, or if the company itself is sold, the qualified
systems retain that status even if the acquiring company is not a small cable
company. The System is presently a "small cable company" but it will no longer
enjoy this status upon consummation by Insight of the TCI transaction.
 
  On February 11, 1997, a Petition for Determination of Effective Competition
filed by Coaxial challenging the certification of the City of Columbus was
granted by the FCC. This petition revoked the City of Columbus' right to
regulate the System's basic cable and equipment rates, and the FCC's right to
regulate the System's CPST rates.
 
  Finally, there are regulations which require cable television systems to
permit customers to purchase video programming on a per channel or a per
program basis without the necessity of subscribing to any tier of service,
other than the basic service tier, unless the cable television system is
technically incapable of doing so. Generally, this exemption from compliance
with the statute for cable television systems that do not have such technical
capability is available until a cable television system obtains the
capability, but not later than December 2002.

 Carriage of Broadcast Television Signals
 
  The 1992 Cable Act contains signal carriage requirements which allow
commercial television broadcast stations that are "local" to a cable
television system (i.e., the system is located in the station's Area of
Dominant Influence) to elect every three years whether to require the cable
television system to carry the station, subject to certain exceptions, or
whether the cable television system will have to negotiate for "retransmission
consent" to carry the station. The next election between must-carry and
retransmission consent will be October 1, 1999. A cable television system is
generally required to devote up to one-third of its activated channel capacity
for the carriage of local commercial television stations whether pursuant to
mandatory carriage requirements or retransmission consent requirements of the
1992 Cable Act. Local non-commercial television stations are also given
mandatory carriage rights, subject to certain exceptions, within the larger
of: (i) a 50 mile radius from the station's city of license; or (ii) the
station's Grade B contour (a measure of signal strength). Unlike commercial
stations, noncommercial stations are not given the option to negotiate
retransmission consent for the carriage of their signal. In addition, cable
television systems have to obtain retransmission consent for the carriage of
all "distant" commercial broadcast stations, except for certain
"superstations" (i.e., commercial satellite-delivered independent stations
such as WGN). To date, compliance with the "retransmission consent" and "must
carry" provisions of the 1992 Cable Act has not had a material effect on the
System, although this result may change in the future depending on such
factors as market conditions, channel capacity and similar matters when such
arrangements are renegotiated. The FCC has initiated a rulemaking proceeding
on the carriage of television signals in high definition and digital formats.
The outcome of this proceeding could have a material effect on the number of
services that a cable operator will be required to carry.
 
 Franchise Fees
 
  Although franchising authorities may impose franchise fees under the 1984
Cable Act, such payments cannot exceed 5% of a cable television system's
annual gross revenues. Under the 1996 Telecom Act, franchising authorities may
not exact franchise fees from revenues derived from telecommunications
services, although they may be able to exact some additional compensation for
the use of public rights-of-way. Franchising authorities are also empowered,
in awarding new franchises or renewing existing franchises, to require cable
television operators to provide cable-related facilities and equipment and to
enforce compliance with voluntary commitments. In the case of franchises in
effect prior to the effective date of the 1984 Cable Act, franchising
authorities may enforce requirements contained in the franchise relating to
facilities, equipment and services, whether or not cable-related. The 1984
Cable Act, under certain limited circumstances, permits a cable operator to
obtain modifications of franchise obligations.
 
 Renewal of Franchises
 
  The 1984 Cable Act and the 1992 Cable Act establish renewal procedures and
criteria designed to protect incumbent franchisees against arbitrary denials
of renewal and to provide specific grounds for franchising authorities to
consider in making renewal decisions, including a franchisee's performance
under the franchise and community needs. Even after the formal renewal
procedures are invoked, franchising authorities and cable television operators
remain free to negotiate a renewal outside the formal process. Nevertheless,
renewal is by no means assured, as the franchisee must meet certain statutory
standards. Even if a franchise is renewed, a franchising authority may impose
new and more onerous requirements such as upgrading facilities and equipment,
although the municipality must take into account the cost of meeting such
requirements. Similarly, if a franchising authority's consent is required for
the purchase or sale of a cable television system or franchises, such
authority may attempt to impose burdensome or onerous franchise requirements
in connection with a request for such consent. Historically, franchises have
been renewed for cable television operators that have provided satisfactory
services and have complied with the terms of their franchises. At this time,
Management is not aware of any current or past material failure on its part to
comply with its franchise agreements. Management believes that it has
generally complied with the terms of its franchises and has provided quality
levels of service.
 
  The 1992 Cable Act makes several changes to the process under which a cable
television operator seeks to enforce his renewal rights which could make it
easier in some cases for a franchising authority to deny renewal.
 
                                      59
<PAGE>
 
Franchising authorities may consider the "level" of programming service
provided by a cable television operator in deciding whether to renew. For
alleged franchise violations occurring after December 29, 1984, franchising
authorities are no longer precluded from denying renewal based on failure to
substantially comply with the material terms of the franchise where the
franchising authority has "effectively acquiesced" to such past violations.
Rather, the franchising authority is estopped if, after giving the cable
television operator notice and opportunity to cure, it fails to respond to a
written notice from the cable television operator of its failure or inability
to cure. Courts may not reverse a denial of renewal based on procedural
violations found to be "harmless error."
 
 Channel Set-Asides
 
  The 1984 Cable Act permits local franchising authorities to require cable
television operators to set aside certain television channels for public,
educational and governmental access programming. The 1984 Cable Act further
requires cable television systems with thirty-six or more activated channels
to designate a portion of their channel capacity for commercial leased access
by unaffiliated third parties to provide programming that may compete with
services offered by the cable television operator. The 1992 Cable Act requires
leased access rates to be set according to a formula determined by the FCC.
 
 Competing Franchises
 
  Questions concerning the ability of municipalities to impose certain
franchise restrictions upon cable television companies have been considered in
several recent federal appellate and district court decisions. These decisions
have been somewhat inconsistent and, until the U.S. Supreme Court rules
definitively on the scope of cable television's First Amendment protections,
the legality of the franchising process and of various specific franchise
requirements is likely to be in a state of flux. It is not possible at the
present time to predict the constitutionally permissible bounds of cable
franchising and particular franchise requirements. However, the 1992 Cable
Act, among other things, prohibits franchising authorities from unreasonably
refusing to grant franchises to competing cable television systems and permits
franchising authorities to operate their own cable television systems without
franchises.
 
 Ownership
 
  The 1996 Telecom Act repealed the statutory ban against local exchange
carriers ("LECs") providing video programming directly to customers within
their local exchange telephone service areas. Consequently, the 1996 Telecom
Act permits telephone companies to compete directly with operations of cable
television systems. Under the 1996 Telecom Act and FCC rules adopted to
implement the 1996 Telecom Act, LECs may provide video service as
broadcasters, common carriers, or cable operators. In addition, LECs and
others may also provide video service through "open video systems" ("OVS"), a
regulatory regime that may give them more flexibility than traditional cable
television systems. OVS operators (including LECs) may operate open video
systems without obtaining a local cable franchise, although they can be
required to make payments to local governmental bodies in lieu of cable
franchise fees. In general, OVS operators must make their systems available to
programming providers on rates, terms and conditions that are reasonable and
nondiscriminatory. Where carriage demand by programming providers exceeds the
channel capacity of an OVS, two-thirds of the channels must be made available
to programmers unaffiliated with the OVS operator.
 
  The 1996 Telecom Act generally prohibits LECs from purchasing cable
television systems (i.e, any ownership interest exceeding 10%) located within
the LEC's telephone service area, prohibits cable operators from purchasing
LECs whose service areas are located within the cable operator's franchise
area, and prohibits joint ventures between operators of cable television
systems and LECs operating in overlapping markets. There are some statutory
exceptions, including a rural exemption that permits buyouts in which the
purchased cable television system or LEC serves a non-urban area with fewer
than 35,000 inhabitants, and exemptions for the purchase of small cable
television systems located in non-urban areas. Also, the FCC may grant waivers
of the buyout provisions in cases where: (i) the operator of a cable
television system or the LEC would be subject to
 
                                      60
<PAGE>
 
undue economic duress if such provisions were enforced; (ii) the system or
facilities would not be economically viable in the absence of a buyout or a
joint venture; or (iii) the anticompetitive effects of the proposed
transaction are clearly outweighed by the transaction's effect in light of
community needs. The respective local franchising authority must approve any
such waiver.
 
  Pursuant to the 1992 Cable Act, the FCC has imposed limits on the number of
cable television systems which a single cable television operator can own. In
general, no cable television operator can have an attributable interest in
cable television systems which pass more than 30% of all homes nationwide.
Attributable interests for these purposes include voting interests of 5% or
more (unless there is another single holder of more than 50% of the voting
stock), officerships, directorships and general partnership interests. The FCC
has recently initiated a Notice of Proposed Rulemaking reviewing these cable
attribution rules, including whether various corporate, financial, partnership
or business relationships that confer influence or control over an entity
engaged in provision of cable services should be subject to regulation. The
FCC has stayed the effectiveness of these rules pending the outcome of the
appeal from the U.S. District Court decision holding the multiple ownership
limit provision of the 1992 Cable Act unconstitutional. The FCC has also
recently issued a Notice of Proposed Rulemaking seeking comment on possible
further revisions to this rule.
 
  The FCC has also adopted rules which limit the number of channels on a cable
television system which can be occupied by national video programming services
in which the entity which owns the cable television system has an attributable
interest. The limit is 40% of the first 75 activated channels.
 
  The 1996 Telecom Act provides that registered utility holding companies and
subsidiaries may provide telecommunications services (including cable
television) notwithstanding the Public Utilities Holding Company Act of 1935,
as amended. Electric utilities must establish separate subsidiaries known as
"exempt telecommunications companies" and must apply to the FCC for operating
authority. Due to their resources, electric utilities could be formidable
competitors to traditional cable television systems.
 
 Equal Employment Opportunities
 
  The 1984 Cable Act includes provisions to ensure that minorities and women
are provided equal employment opportunities within the cable television
industry. The statute requires the FCC to adopt reporting and certification
rules that apply to all cable television system operators with more than five
full-time employees. Pursuant to the requirements of the 1992 Cable Act, the
FCC has imposed more detailed annual Equal Employment Opportunities reporting
requirements on cable operators and has expanded those requirements to all
multichannel video service distributors. Failure to comply with the Equal
Employment Opportunities requirements can result in the imposition of fines
and/or other administrative sanctions, or may, in certain circumstances, be
cited by a franchising authority as a reason for denying a franchisee's
renewal request.
 
 Privacy
 
  The 1984 Cable Act imposes a number of restrictions on the manner in which
cable television operators can collect and disclose data about individual
system customers. The statute also requires that the system operator
periodically provide all customers with written information about its policies
regarding the collection and handling of data about customers, their privacy
rights under federal law and their enforcement rights. In the event that a
cable television operator were found to have violated the customer privacy
provisions of the 1984 Cable Act, it could be required to pay damages,
attorneys' fees and other costs. Under the 1992 Cable Act, the privacy
requirements were strengthened to require that cable television operators take
such actions as are necessary to prevent unauthorized access to personally
identifiable information.
 
 Franchise Transfers
 
  The 1992 Cable Act requires franchising authorities to act on any franchise
transfer request submitted after December 4, 1992 within 120 days after
receipt of all information required by FCC regulations and by the franchising
authority. Approval is deemed to be granted if the franchising authority fails
to act within such period.
 
                                      61
<PAGE>
 
 Technical Requirements
 
  The FCC has imposed technical standards applicable to all classes of
channels which carry downstream National Television System Committee ("NTSC")
video programming. The FCC also has adopted additional standards applicable to
cable television systems using frequencies in the 108 to 137 MHz and 225 to
400 MHz bands in order to prevent harmful interference with aeronautical
navigation and safety radio services and has also established limits on cable
television system signal leakage. Periodic testing by cable television
operators for compliance with the technical standards and signal leakage
limits is required and an annual filing of the results of these measurements
is required. The 1992 Cable Act requires the FCC to periodically update its
technical standards to take into account changes in technology. Under the 1996
Telecom Act, local franchising authorities may not prohibit, condition or
restrict a cable television system's use of any type of subscriber equipment
or transmission technology.
 
  The FCC has adopted regulations to implement the requirements of the 1992
Cable Act designed to improve the compatibility of cable television systems
and consumer electronics equipment. These regulations, inter alia, generally
prohibit cable television operators from scrambling their basic service tier.
The 1996 Telecom Act directs the FCC to set only minimal standards to assure
compatibility between television sets, VCRs and cable television systems, and
to rely on the marketplace. Pursuant to the 1992 Cable Act, the FCC has
adopted rules to assure the competitive availability to consumers of customer
premises equipment, such as converters, used to access the services offered by
cable television systems and other multichannel video programming distributors
("MVPD"). Pursuant to those rules, consumers are given the right to attach
compatible equipment to the facilities of their MVPD so long as the equipment
does not harm the network, does not interfere with the services purchased by
other customers, and is not used to receive unauthorized services. As of July
1, 2000, MVPDs (other than DBS operators) are required to separate security
from non-security functions in the customer premises equipment which they sell
or lease to their customers and offer their customers the option of using
component security modules obtained from the MVPD with set-top units purchased
or leased from retail outlets. As of January 1, 2005, MVPDs will be prohibited
from distributing new set-top equipment integrating both security and non-
security functions to their customers.
 
  Pursuant to the 1992 Cable Act, the FCC has adopted rules implementing an
Emergency Alert System ("EAS"). The rules require all cable television systems
to provide an audio and video EAS message on at least one programmed channel
and a video interruption and an audio alert message on all programmed
channels. The audio alert message is required to state which channel is
carrying the full audio and video EAS message. The FCC rules permit cable
television systems either to provide a separate means of alerting persons with
hearing disabilities of EAS messages, such as a terminal that displays EAS
messages and activates other alerting mechanisms or lights, or to provide
audio and video EAS messages on all channels. Cable television systems with
10,000 or more basic subscribers per headend will be required to install EAS
equipment capable of providing audio and video EAS messages on all programmed
channels by December 31, 1998. Cable television systems with 5,000 or more but
fewer than 10,000 basic subscribers per headend will have until October 1,
2002 to comply with that requirement. Cable television systems with fewer than
5,000 basic subscribers per headend will have a choice of providing either a
national level EAS message on all programmed channels or installing EAS
equipment capable of providing audio alert messages on all programmed
channels, a video interrupt on all channels, and an audio and video EAS
message on one programmed channel. This must be accomplished by October 1,
2002.
 
 Pole Attachments
 
  The FCC currently regulates the rates and conditions imposed by certain
public utilities for use of their poles unless state public service
commissions are able to demonstrate that they adequately regulate the rates,
terms and conditions of cable television pole attachments. A number of states
and the District of Columbia have certified to the FCC that they adequately
regulate the rates, terms and conditions for pole attachments. Ohio, the state
in which the System operates, has made such a certification. In the absence of
state regulation, the FCC administers such pole attachment and conduit use
rates through use of a formula which it has devised. Pursuant
 
                                      62
<PAGE>
 
to the 1996 Telecom Act, the FCC has adopted a new rate formula for any
attaching party, including cable television systems, which offer
telecommunications services. This new formula will result in higher attachment
rates than at present, but they will apply only to cable television systems
which elect to offer telecommunications services. Any increases pursuant to
this new formula will not begin until 2001, and will be phased in by equal
increments over the five ensuing years. The FCC has also initiated a
proceeding to determine whether it should adjust certain elements of the
current rate formula. If adopted, these adjustments could increase rates for
pole attachments and conduit space.
 
 Other FCC Matters
 
  FCC regulation pursuant to the Communications Act also includes matters
regarding a cable television system's carriage of local sports programming;
restrictions on origination and cablecasting by cable television operators;
rules governing political broadcasts; nonduplication of network programming;
deletion of syndicated programming; registration procedure and reporting
requirements; customer service; closed captioning; obscenity and indecency;
program access and exclusivity arrangements; and limitations on advertising
contained in nonbroadcast children's programming.
 
  The FCC recently adopted new procedural guidelines governing the disposition
of home run wiring (a line running to an individual subscriber's unit from a
common feeder or riser cable) in MDUs. MDU owners can use these new rules to
attempt to force cable television operators without contracts to either sell,
abandon or remove home run wiring and terminate service to MDU subscribers
unless operators retain rights under common or state law to maintain ownership
rights in the home run wiring.
 
  The 1996 Telecom Act requires video programming distributors to employ
technology to restrict the reception of programming by persons not subscribing
to those channels. In the case of channels primarily dedicated to sexually-
oriented programming, the distributor must fully block reception of the audio
and video portion of the channels; a distributor that is unable to comply with
this requirement may only provide such programming during a "safe harbor"
period when children are not likely to be in the audience, as determined by
the FCC. With respect to other kinds of channels, the 1996 Telecom Act
requires that the audio and video portions of the channel be fully blocked, at
no charge, upon request of the person not subscribing to the channel.
 
 Copyright
 
  Cable television systems are subject to federal copyright licensing covering
carriage of broadcast signals. In exchange for making semi-annual payments to
a federal copyright royalty pool and meeting certain other obligations, cable
television operators obtain a statutory license to retransmit broadcast
signals. The amount of this royalty payment varies, depending on the amount of
system revenues from certain sources, the number of distant signals carried,
and the location of the cable television system with respect to over-the-air
television stations. Any future adjustment to the copyright royalty rates will
be done through an arbitration process to be supervised by the U.S. Copyright
Office. Cable television operators are liable for interest on underpaid and
unpaid royalty fees, but are not entitled to collect interest on refunds
received for overpayment of copyright fees.
 
  Various bills have been introduced into Congress over the past several years
that would eliminate or modify the cable television compulsory license.
Without the compulsory license, cable television operators would have to
negotiate rights from the copyright owners for all of the programming on the
broadcast stations carried by cable television systems. Such negotiated
agreements would likely increase the cost to cable television operators of
carrying broadcast signals. The 1992 Cable Act's retransmission consent
provisions expressly provide that retransmission consent agreements between
television broadcast stations and cable television operators do not obviate
the need for cable operators to obtain a copyright license for the programming
carried on each broadcaster's signal.
 
  Copyrighted music performed in programming supplied to cable television
systems by pay cable networks (such as HBO) and basic cable networks (such as
USA Network) is licensed by the networks through private
 
                                      63
<PAGE>
 
agreements with the American Society of Composers and Publishers ("ASCAP") and
BMI, Inc. ("BMI"), the two major performing rights organizations in the United
States. As a result of extensive litigation, both ASCAP and BMI now offer
"through to the viewer" licenses to the cable networks which cover the
retransmission of the cable networks' programming by cable television systems
to their customers.
 
  Licenses to perform copyrighted music by cable television systems
themselves, including on local origination channels, in advertisements
inserted locally on cable television networks, and in cross-promotional
announcements, must be obtained by the cable television operator. Cable
television industry negotiations with ASCAP, BMI and SESAC, Inc. (a smaller
performing rights organization) are in progress.
 
STATE AND LOCAL REGULATION
 
  Cable television systems generally are operated pursuant to nonexclusive
franchises, permits or licenses granted by a municipality or other state or
local government entity. The terms and conditions of franchises vary
materially from jurisdiction to jurisdiction, and even from city to city
within the same state, historically ranging from reasonable to highly
restrictive or burdensome. Franchises generally contain provisions governing
fees to be paid to the franchising authority, length of the franchise term,
renewal, sale or transfer of the franchise, territory of the franchise, design
and technical performance of the system, use and occupancy of public streets
and number and types of cable television services provided. The terms and
conditions of each franchise and the laws and regulations under which it was
granted directly affect the profitability of the cable television system. The
1984 Cable Act places certain limitations on a franchising authority's ability
to control the operation of a cable television system. The 1992 Cable Act
prohibits exclusive franchises, and allows franchising authorities to exercise
greater control over the operation of franchised cable television systems,
especially in the area of customer service and rate regulation. The 1992 Cable
Act also allows franchising authorities to operate their own multichannel
video distribution system without having to obtain a franchise and permits
states or local franchising authorities to adopt certain restrictions on the
ownership of cable television systems. Moreover, franchising authorities are
immunized from monetary damage awards arising from regulation of cable
television systems or decisions made on franchise grants, renewals, transfers
and amendments. The 1996 Telecom Act prohibits a franchising authority from
either requiring or limiting a cable television operator's provision of
telecommunications services.
 
  Various proposals have been introduced at the state and local levels with
regard to the regulation of cable television systems, and a number of states
have adopted legislation subjecting cable television systems to the
jurisdiction of centralized state governmental agencies, some of which impose
regulation of a character similar to that of a public utility. To date, Ohio,
the state in which the System currently operates, has not enacted state level
regulation.
 
  The foregoing does not purport to describe all present and proposed federal,
state and local regulations and legislation relating to the cable television
industry. Other existing federal regulations, copyright licensing and, in many
jurisdictions, state and local franchise requirements, currently are the
subject of a variety of judicial proceedings, legislative hearings and
administrative and legislative proposals which could change, in varying
degrees, the manner in which cable television systems operate. Neither the
outcome of these proceedings nor their impact upon the cable television
industry or the System can be predicted at this time.

management fees of 3.0% of gross revenues of Insight Ohio. See "Management--
Executive and Other Compensation."
 
  IHO is entitled to reimbursement from Insight Ohio for all direct, out-of-
pocket expenses incurred by or on behalf of IHO that directly relate to its
management of the business and operations of Insight Ohio, including any such
expenses incurred in connection with the management of the Discount Notes
Issuers. However, IHO is not entitled to reimbursement from Insight Ohio for
corporate overhead (including employee bonuses and health, welfare,
retirement, and other employee benefits and overhead expenses of its corporate
office management, development, internal accounting, and finance management
personnel).
 
  Due to its relationship with MediaOne (formerly Continental Cablevision),
Insight expects to continue to provide programming discounts to the System
through November 1999. After such date, Insight believes that through its
strategic alliances with other major MSOs, utilizing programming cooperatives
or through its own purchasing power, it will be able to continue to obtain
programming for the System at a cost lower than that presently available to
Coaxial.
 
COAXIAL
 
 Tierra Associates
 
  Coaxial leased office space in a building located at 3770/3776 East
Livingston Avenue, Columbus, Ohio. The building was owned by Tierra
Associates, an Ohio general partnership that was owned by the principals of
the Individual LLCs. Coaxial paid Tierra Associates $108,000 annually pursuant
to the lease for such space. Pursuant to the terms of the Contribution
Agreement, Coaxial acquired title to this building and contributed it to
Insight Ohio upon consummation of the System Acquisition.
 
 MetroComm AxS L.P. ("MetroComm")
 
  MetroComm provides competitive telephone service in the Columbus market.
MetroComm is 50% owned by Time Warner AxS of Columbus L.P. and 50% owned by
MetroComm Inc. (which is owned by Barry Silverstein, Dennis McGillicuddy and
D. Stevens McVoy, who are the sole members of each of their respective
Individual LLCs, and Dan Coy, the chief executive officer of MetroComm).
MetroComm contracted with Coaxial to build the necessary fiber plant needed by
MetroComm to service its customers that were in Coaxial's service area.
Coaxial then leased the fiber plant to MetroComm at a contracted price. In
1997, Coaxial received $187,180 in fiber lease revenues from MetroComm.
Coaxial negotiated a buy-out of the lease as of June 29, 1998. The fiber
continues to be used by MetroComm under a 30-year Indefeasible Right of Use
Agreement with reduced revenues. Coaxial also provided accounting services for
MetroComm. In 1997, Coaxial received $35,276 for such services. As of June 30,
1998, MetroComm owed Coaxial $98,461.
 
 Paxton Cable Television Inc.
 
  Paxton Cable Television Inc. had a note payable to Coaxial for $2,448,141
(as of June 30, 1998) which accrued interest at the average interest rate
charged by The Chase Manhattan Bank to Coaxial for its long-term financing.
Principal and interest is not due until June 30, 2000. This note was
distributed by Coaxial to its shareholders (the principals of the Individual
LLCs) upon the consummation of the System Acquisition and was not assumed by
Insight Ohio.
 
 Coaxial Communications of Southern Ohio, Inc.
 
  Coaxial allocated certain management costs to Coaxial Communications of
Southern Ohio, Inc., which is wholly-owned by the principals of the Individual
LLCs. The total amount allocated for 1997 was $284,400. Under a related party
account, $18.5 million was owed to Southern Ohio as of June 30, 1998. This
account was settled upon the consummation of the System Acquisition.

 Coaxial Associates of Columbus I, Coaxial Associates of Columbus II and
Phoenix Associates
 
  Coaxial Associates of Columbus I ("Columbus I"), Coaxial Associates of
Columbus II ("Columbus II") and Phoenix are non-operating partnerships which
share common ownership and which were co-borrowers and co-obligors under the
Chase Credit Facility. The three entities exist due to several debt and tax
obligations which existed among these entities and former limited partners of
Columbus I and Columbus II. Coaxial funded the debt obligations of these
entities, which do not conduct operations. The result was a series of related
party notes and receivables/payables to and between Coaxial, Columbus I,
Columbus II and Phoenix. These notes and related party receivables/payables
with Coaxial were settled prior to the consummation of the System Acquisition.
Phoenix was a co-issuer of the Original Notes as described under "Prospectus
Summary--Ownership Structure" and Phoenix owns none of the Senior Notes
Collateral. All notes and related party receivables/payables with Phoenix were
settled upon the consummation of the System Acquisition excluding certain
amounts and notes due from Columbus I, Columbus II and the partners of
Phoenix, which were retained for tax purposes (the "Excluded Assets").
 
                          PRINCIPAL SECURITY HOLDERS
 
  The outstanding shares of common stock of Coaxial are owned by the
Individual LLCs as described in the table below. All of the outstanding shares
of common stock of Coaxial Financing Corp. and all of the outstanding
partnership interests of Phoenix Associates are wholly-owned directly or
indirectly by the individuals indicated in the footnotes to the table in the
same ownership percentages as the respective Individual LLCs' ownership in
Coaxial. IHO is the manager of each of the Individual LLCs and thereby
effectively controls the business of each of such Individual LLCs and Coaxial.
Accordingly, Insight and members of its executive management may be deemed to
beneficially own (as defined by Rule 13d-3 under the Exchange Act) all of the
outstanding shares of common stock of Coaxial. See "Prospectus Summary--
Ownership Structure" and "Management."

                            THE SYSTEM ACQUISITION
 
THE CONTRIBUTION AGREEMENT
 
  The following summary of certain provisions of the Contribution Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Contribution Agreement.
 
  On June 30, 1998, Coaxial and Insight entered into a Contribution Agreement,
as amended on July 15, 1998 and August 21, 1998 (the "Contribution
Agreement"), pursuant to which on August 21, 1998, as part of the Financing
Plan, Coaxial contributed to Insight Ohio, a newly organized Delaware limited
liability company, substantially all of the assets comprising the System, and
Insight, through IHO, contributed to Insight Ohio $10.0 million in cash.
Coaxial may be required to make future cash contributions to Insight Ohio to
offset any diminution of value of the contributed assets under certain
circumstances. There will be no other assessments for additional capital
contributions by the members. In accordance with the terms and conditions of
the Contribution Agreement, Insight Ohio assumed and undertook to perform
certain obligations and liabilities related to the contributed assets. As a
result of the Financing Plan, IHO and Coaxial own 75% and 25%, respectively,
of the common membership interests of Insight Ohio. IHO's common membership
interests are classified as "Class A" and Coaxial's common membership
interests are classified as "Class B." Coaxial also owns the Preferred
Interests of Insight Ohio. IHO serves as the manager of Insight Ohio and each
of the Individual LLCs and thereby has effective control of the management and
affairs of Insight Ohio.
 
  The Contribution Agreement contains customary provisions for such
agreements, including representations and warranties with respect to the
condition and operations of the business.
 
OPERATING AGREEMENT OF INSIGHT OHIO
 
  The following summary of certain provisions of the Operating Agreement of
Insight Ohio does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the Operating
Agreement. Capitalized terms used in the following summary and not otherwise
defined in this Prospectus have the meanings ascribed to them in the Operating
Agreement.
 
 General
 
  The Operating Agreement of Insight Ohio provides for the formation,
organization and operation of Insight Ohio and for the respective rights,
obligations and interests of the members of Insight Ohio to each other and to
Insight Ohio. In addition, the Operating Agreement sets forth certain
additional agreements and understandings among its members and the sole
members of each of the Individual LLCs, which own Coaxial (Barry Silverstein,
Dennis McGillicuddy and D. Stevens McVoy, who, together with their respective
permitted successors and assigns, are referred to as the "Principals"),
concerning the ownership and operation of Insight Ohio and Coaxial.
 
  Insight Ohio will be dissolved upon the happening of certain events,
including, among others:
  . December 31, 2058;
  . consent of the Principals to the resignation of Insight as manager;
  . the affirmative vote of the holders of a majority of the outstanding
    Voting Interests (as defined under "--Management" below), subject to
    certain conditions;
  . the sale of all or substantially all of the assets of Insight Ohio; and
  . any other event causing the dissolution of a limited liability company.
 
  IHO and Coaxial are the members of Insight Ohio. The Principals, although
parties to the Operating Agreement, are not members of Insight Ohio. The
members of Insight Ohio generally do not have any authority to act for, or
assume any obligation or responsibility on behalf of, Insight Ohio. The
members are not personally liable for the expenses, liabilities or obligations
of Insight Ohio, and in no event shall either member be required to make up a
deficiency in its capital account upon the dissolution and termination of
Insight Ohio.
 
                                      69
<PAGE>
 
 Distributions
 
  Distributions on the Preferred Interests will be in such amounts as to allow
for the payment of interest on the Notes and the Discount Notes, with the
Series A Preferred Interests to receive payments in priority to the Series B
Preferred Interests. Insight Ohio will then make certain distributions to its
members holding common membership interests in an amount equal to an estimate
of certain tax liabilities recognized by the members or their owners. Insight
Ohio will then distribute to the Manager a management return equal to 3% of
gross revenues. Thereafter, distributions are to be made, as determined by the
Management Committee, to the members in proportion to their common membership
interests. Distributions in respect of the membership interests of Insight
Ohio are restricted under the Indenture and the Discount Notes Indenture and
will be restricted as well under the Senior Credit Facility. See "Description
of the Notes--Covenants--Limitation on Restricted Payments."
 
  If (i) any default (other than a notification or delivery default) shall
have occurred and be continuing under either the Indenture or the Discount
Notes Indenture, or if IHO in good faith determines that such a default under
either the Indenture or the Discount Notes Indenture is reasonably likely to
occur, and (ii) IHO determines in good faith that, as a result of such
existing or anticipated default, it would be in the best interests of Insight
Ohio for Insight Ohio not to make any distribution required to be made with
respect to the Preferred Interests, and (iii) IHO notifies the Principals in
writing that it has made such determination, then IHO may cause Insight Ohio
not to make such distribution until such time as IHO determines that it is no
longer in the best interests of Insight Ohio for Insight Ohio not to make such
distribution.
 
 Redemption of Preferred Interests
 
  Insight Ohio may not redeem the Series A Preferred Interests, in whole or in
part, without the consent of the Principals, except upon certain events.
Insight Ohio will be required to redeem the Series A Preferred Interests in
full upon acceleration or maturity of the Notes, commencement of the
enforcement of remedies under the Pledge Agreement in respect of the Senior
Notes Collateral, the passage of ten days and upon request for redemption by
the holders of the Notes. If Insight Ohio redeems all or part of the Series A
Preferred Interests, the redemption price will equal the sum of (A) the amount
that would be distributed to the holder of the redeemed Series A Preferred
Interests upon dissolution and liquidation of Insight Ohio, assuming that
Insight Ohio had sufficient assets to make the full liquidating distributions
provided for in the Operating Agreement, plus (B) the amount of any premium
required to be paid by the Issuers to the holders of the Notes in connection
with the Issuers' use of the proceeds of the redemption of the Series A
Preferred Interests to repay or purchase the Notes.
 
  Insight Ohio is also required to redeem the Series B Preferred Interests in
full on the tenth anniversary of the closing of the Discount Notes Offering.
Insight Ohio may not otherwise redeem the Series B Preferred Interests, in
whole or in part, without the consent of the Principals, except upon certain
events. Insight Ohio will be required to redeem the Series B Preferred
Interests in full upon acceleration of the Discount Notes, commencement of the
enforcement of remedies under the Discount Notes pledge agreement in respect
of the Discount Notes collateral (as defined in the Discount Notes Indenture),
the passage of ten days and upon request for redemption by the holders of the
Discount Notes. Notwithstanding the foregoing, Insight Ohio will not redeem
the Series B Preferred Interests if it is also required to redeem the Series A
Preferred Interests and it has not yet done so. If Insight Ohio redeems all or
part of the Series B Preferred Interests, the redemption price will equal the
sum of (A) the amount that would be distributed to the holder of the redeemed
Series B Preferred Interests upon dissolution and liquidation of Insight Ohio,
assuming that Insight Ohio had sufficient assets to make the full liquidating
distributions provided for in the Operating Agreement, plus (B) the amount of
any premium required to be paid by the Issuers to the holders of the Discount
Notes in connection with the Discount Notes Issuers' use of the proceeds of
the redemption of the Series B Preferred Interests to repay or purchase the
Discount Notes.
 
  The Series A Preferred Interests have priority over the Series B Preferred
Interests with respect to redemption, if both Preferred Interests are required
to be redeemed.
 
 Management
 
  The Operating Agreement provides that certain decisions will be made by
holders of a majority of Insight Ohio's outstanding "Voting Interests." The
term "Voting Interests" means the Series A Preferred Interests and
 
                                      70
<PAGE>
 
the Series B Preferred Interests, collectively, except that, following certain
events, "Voting Interests" will mean the common membership interests. A
majority of the Preferred Interests is determined based on the original
capital account balances attributable to the interests, and a majority of the
common membership interests is determined based on the number of units
assigned to the interests. The Preferred Interests will become non-voting upon
the enforcement of remedies under the Pledge Agreement.
 
  Insight Ohio is managed by a Management Committee consisting of four
Representatives, three of which shall be appointed from time to time by
holders of a majority of the outstanding Voting Interests and one of which
shall be appointed from time to time by the Principals. The members of the
Management Committee are not compensated or reimbursed by Insight Ohio for
serving on the Management Committee.
 
  The Operating Agreement permits the Management Committee to delegate to the
manager of Insight Ohio and the officers of Insight Ohio any of its authority
under the Operating Agreement. In accordance with this authorization, the
Management Committee delegated broad authority to the manager of Insight Ohio
to manage the business and operations of Insight Ohio. The Principals will
have the right to appoint a co-Manager in the event of a breach by IHO of
certain provisions of the Operating Agreement. The Operating Agreement
prohibits Insight Ohio and any of its subsidiaries from taking certain
actions, including most significant dispositions of assets, without the
consent of the Principals, which may be withheld by the Principals in their
sole discretion.
 
  The Operating Agreement names IHO as the Manager of Insight Ohio. IHO may
not resign as the Manager without the consent of holders of a majority of the
outstanding Voting Interests and the consent of the Principals (except in the
case of a permitted transfer of all of IHO's membership interest to a
successor, who will then become the Manager). If holders of a majority of the
outstanding Voting Interests and the Principals consent to IHO's resignation
as Manager, Insight Ohio will dissolve unless the members and the Principals
elect to continue the business of Insight Ohio and agree to a successor
Manager.
 
  The Manager is entitled to reimbursement from Insight Ohio for certain
expenses incurred by or on behalf of the Manager that directly relate to its
management of the business and operations of Insight Ohio, including any such
expenses incurred in connection with the management of the Individual LLCs.
However, the Manager is not entitled to reimbursement from Insight Ohio for
corporate overhead.
 
 Refinancing and Modification of Indebtedness
 
  IHO agrees to use commercially reasonable efforts to obtain and submit to
Coaxial and the Principals a proposal from a financial institution of
nationally recognized standing for the refinancing of the Notes at or prior to
its maturity. In addition, IHO agrees to use commercially reasonable efforts
to obtain and submit to Coaxial and the Principals either a proposal from a
financial institution of nationally recognized standing for the refinancing of
the Notes and the Discount Notes or a proposal from the holders of the Notes
and the Discount Notes to modify the terms thereof if any portion of the Notes
or the Discount Notes has become due and payable before its stated maturity or
if Insight Ohio failed to make, or is expected to be unable to make, any
required distributions with respect to the Preferred Interests. IHO also has
the right to obtain and submit to Coaxial and the Principals at any time and
from time to time a proposal from a financial institution of nationally
recognized standing for the refinancing of the Notes and the Discount Notes.
 
  Upon the satisfaction of certain conditions, the Principals are required to
consent to the refinancing or modification of the Notes and the Discount Notes
as proposed by IHO. In addition, under the circumstances described in the
preceding paragraph where IHO is required to use commercially reasonable
efforts to obtain a proposal for the refinancing or modification of the Notes
and the Discount Notes, if the Principals are not required to consent, and do
not consent, to any proposed refinancing or modification, then the members of
the Individual LLCs will sell all the outstanding membership interests of the
Individual LLCs to IHO or to a person designated by IHO for nominal
consideration. The members of the Individual LLCs may also sell all of the
outstanding membership interests of the Individual LLCs under certain other
circumstances to IHO or a person designated by IHO for nominal consideration.
Certain conditions to the Principals' obligation to consent to any refinancing
or modification of the Notes and the Discount Notes depend on the Principals
receipt of an opinion of the Principals' counsel.
 
                                      71
<PAGE>
 
  Subject to the Indenture and the Discount Notes Indenture, Insight Ohio is
permitted to make loans to IHO or any affiliate of IHO for the purpose of
funding the acquisition by IHO or its affiliate of any of the outstanding
Notes and the Discount Notes. The terms of any such loan will (i) provide that
all obligations and liabilities of IHO or its affiliate with respect to the
loan would be secured by its interest in the Notes or Discount Notes so
purchased, and any replacements or proceeds thereof (but such loan shall
otherwise be non-recourse to IHO or its affiliate); (ii) require the payment
to Insight Ohio, either as principal, interest, or additional interest, of all
amounts received by IHO or its affiliate with respect to the Notes or the
Discount Notes so purchased; and (iii) if made to an affiliate of IHO, require
that it remain an affiliate thereof.
 
  IHO agrees that, except as specifically permitted by the Operating
Agreement, neither IHO nor any of its affiliates (including Insight Ohio) will
take any willful or intentional action in any capacity that is intended to
have, and has, the effect of modifying the structure of the Notes or the
Discount Notes (such as by imposing any covenants on any person other than an
Issuer or a Discount Notes Issuer that are not imposed on such person under
the Notes or the Discount Notes as it will exist at the Closing or agreeing
that any person or its assets would be liable or otherwise responsible for the
payment or collection of the Notes or the Discount Notes, or for the
performance of the obligations of any Issuer or any Discount Notes Issuer, to
a greater extent than such person or its assets is liable or otherwise
responsible under the Notes and the Discount Notes as then in effect).
 
 Reimbursement of Certain Expenses
 
  Insight Ohio will reimburse the Issuers, the Discount Notes Issuers and the
Individual LLCs for all direct, out-of-pocket expenses incurred by or on
behalf of the Issuers, the Discount Notes Issuers and the Individual LLCs in
complying with the terms of the Indenture and the Discount Notes Indenture
(excluding any payment of principal or interest under the Notes or the
Discount Notes). Insight Ohio will also pay, or shall reimburse the Issuers,
the Discount Notes Issuers and the Individual LLCs for, any amounts required
to be paid by any Issuer, Discount Notes Issuer or Individual LLC as a result
of any indemnification or reimbursement obligation arising under the Indenture
or the Discount Notes Indenture or otherwise arising in connection with the
offer or sale of any of the Notes, the Discount Notes or any replacement
thereof.
 
 Capital Defaults
 
  If IHO breaches certain specified covenants under the Operating Agreement,
then, subject to the receipt of any required consents, approvals, waivers, or
authorizations of governmental authorities, (A) the size of the Management
Committee will be increased to six members, three of which shall be appointed
by holders of a majority of the outstanding Voting Interests and three of
which shall be appointed by the Principals, and (B) a person designated by the
Principals shall become an additional Manager of Insight Ohio and shall have
the authority to exercise, to the same extent as IHO, all powers designated in
this Agreement as powers of the Manager or delegated to the Manager by the
Management Committee, including the power to cause distributions to be made
with respect to the Series A Preferred Interests and the Series B Preferred
Interests. In the event of such a breach, IHO will indemnify the Issuers and
the Principals for certain damages, including certain tax liabilities, arising
from or relating to the breach.
 
 Transfers of Interests
 
  Neither member may sell, assign, transfer, or otherwise dispose of, or
pledge, hypothecate, or otherwise encumber all or any part of its membership
interest (whether voluntary, involuntary or by operation of law), unless
approved by the other member and the Principals, subject to a number of
significant exceptions, including the following: (i) a member may transfer its
membership interest to one of its affiliates; (ii) a permitted redemption of
the Preferred Interests; (iii) Coaxial may pledge its membership interest to
secure the Notes, the Discount Notes or any replacement thereof and IHO may
pledge its membership interest to secure Insight's senior debt; (iv) IHO may
sell any of its common interest if it affords Coaxial "tag-along" rights with
respect to Coaxial's common membership interest; (v) Coaxial shall sell all or
part of its common membership interest if IHO exercises its "drag-along"
rights upon a sale by IHO of all or part of its common membership interest;
and (vi) Coaxial may put its common membership interest to IHO and IHO may
call Coaxial's common membership interest upon a change in control of IHO.
 
 
                                      72
<PAGE>
 
  In addition, IHO may elect at any time, by delivering written notice of its
election to Coaxial and the Principals, to require that a person designated by
the Principals purchase all of IHO's membership interest, for a nominal
purchase price. The closing of the purchase and sale of IHO's membership
interest pursuant to this provision would occur on a date to be specified by
the Principals that is within 180 days after the Principals' receipt of IHO's
election. IHO would cease to manage Insight Ohio and the Individual LLCs upon
consummation of the sale.
 
  IHO has agreed with Coaxial and the Principals that, if any transfer by IHO
of all or any part of its membership interest or any other transaction
involving ownership of IHO would trigger the right of any holder of any of the
Notes and Discount Notes to require that such Notes and Discount Notes be
repaid, purchased, or redeemed, then, as an additional condition to the
consummation of such transfer or other transaction, IHO or its assignee will
(a) agree to purchase such Notes and Discount Notes from the holder thereof in
the event the holder elects to require that such Notes and Discount Notes be
repaid, purchased, or redeemed, and, upon such purchase, IHO or its assignee
shall waive any right to require that such Notes and Discount Notes be repaid,
purchased, or redeemed, or (b) obtain an irrevocable, binding agreement of the
holder of such Notes and Discount Notes not to require that such Notes and
Discount Notes be repaid, purchased, or redeemed upon the consummation of such
transfer or other transaction. Like the other terms of the Operating
Agreement, this covenant of IHO will not be enforceable by any holder of the
Notes and Discount Notes.
 
 Indemnification and Exculpation
 
  Insight Ohio is required to indemnify, defend, and hold harmless its members
and related parties for costs and damages incurred by reason of acts performed
or omitted to be performed by such persons in connection with the business of
Insight Ohio, except in the case of fraud, gross negligence, breach of
fiduciary duty, willful misconduct or a breach of the Operating Agreement by
the indemnified party. The members and their related parties will not liable,
in damages or otherwise, to Insight Ohio or to either member for losses that
arise from acts performed or omitted to be performed in connection with the
business of Insight Ohio, except in the case of fraud, gross negligence,
breach of fiduciary duty, willful misconduct, or a breach of the Operating
Agreement by the member or its related party.
 
 Rights of Principals
 
  None of the rights of the Principals under the Operating Agreement may be
assigned or otherwise transferred except, following the death of a Principal,
pursuant to the laws of descent and distribution. All rights of the Principals
under the Operating Agreement will terminate at such time as the Principals
cease to own, directly or indirectly, any interest in Insight Ohio.
 
 Amendments
 
  The Operating Agreement may only be modified or amended with the consent of
all the members and the Principals.
 
                      DESCRIPTION OF GOVERNING DOCUMENTS
 
INDIVIDUAL LLCS' OPERATING AGREEMENTS AND MANAGEMENT AGREEMENTS
 
  All of the issued and outstanding capital stock of Coaxial is held by the
Individual LLCs. Each Individual LLC is governed by the Delaware Limited
Liability Company Act and its operating agreement. The operating agreements of
the Individual LLCs are substantially identical. Each operating agreement
limits the purposes of the Individual LLC to acquiring, owning, holding and
disposing of shares of capital stock of Coaxial, or any assets or property
acquired in exchange for such shares of capital stock. The sole member of each
Individual LLC has contributed to his Individual LLC all his shares of Coaxial
capital stock. As a pass-through entity, all profits and losses of each
Individual LLC are allocated to its sole member.
 
  The responsibility and control of the management of each Individual LLC is
granted to the member. The member may delegate to a manager any of the power
and authority of the member pursuant to a written management agreement.
However, notwithstanding any contrary provision in any such management
agreement,
 
                                      73
<PAGE>
 
no Individual LLC shall take, and the manager shall not cause such Individual
LLC to take, any of the following actions without the consent of the member:
  . sell or issue any membership interests in the Individual LLC;
  . engage in any transaction with Insight Ohio, IHO, any successor manager
    or any of their respective affiliates;
  . engage in any business activity other than (i) the acquisition, ownership
    and disposition of shares of Coaxial and (ii) the performance of its
    obligations under any agreement or other instrument evidencing the
    Discount Notes or any replacement thereof or pursuant to which the
    Discount Notes or any replacement thereof exists;
  . consent to any amendment to any provision of the Articles of
    Incorporation of Coaxial;
  . amend, alter, or repeal any provision of the Code of Regulations of
    Coaxial;
  . purchase, redeem, or otherwise acquire any membership interest in the
    Individual LLC;
  . merge or consolidate with or into any other person;
  . liquidate or dissolve;
  . acquire, by purchase or lease, any assets;
  . sell, dispose of, pledge or otherwise encumber any part of its assets,
    except, with respect to shares of Coaxial, as permitted by any agreement
    or other instrument pursuant to which the Discount Notes or any
    replacement thereof exists;
  . incur or prepay any indebtedness (including any Discount Notes or any
    replacement thereof other than in accordance with their terms);
  . agree to any reorganization, arrangement, or similar adjustment of its
    debts under any law relating to bankruptcy, insolvency, or reorganization
    or relief of debtors;
  . enter into or amend any contract or other agreement, including any
    agreement with respect to the incurring or repayment of any indebtedness
    (including any Discount Notes or any replacement thereof);
  . take any action that would cause Coaxial's election to be treated as an
    "S corporation" under the Internal Revenue Code to be terminated or
    revoked; or
  . hire any employee or independent contractor or pay any compensation to
    any of its officers or directors.
 
  Each Individual LLC has entered into a management agreement (the "Management
Agreement") with IHO (the "Manager"). Except as provided below, each
Individual LLC has delegated to the Manager all rights and powers of the
member of such Individual LLC with respect to the management and conduct of
the Individual LLC's activities and operation insofar as they relate to the
ownership of shares of Coaxial and any Discount Notes, and its performance of
its obligations under any agreement or other instrument evidencing the
Discount Notes or pursuant to which the Discount Notes exists. The Manager
does not have any authority, among other things, to:
  . take any action which pursuant to the operating agreement of such
    Individual LLC may not be delegated to the Manager;
  . cause the Individual LLC to exercise any of its rights as a shareholder
    of Coaxial under the Close Corporation Agreement of Coaxial (as described
    under "--Close Corporation Agreement" below); or
  . take any action with respect to any "Reserved Matter" as that term is

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
SENIOR CREDIT FACILITY
 
  Coaxial and Insight have entered into a commitment letter with Canadian
Imperial Bank of Commerce pursuant to which Insight Ohio is expected to enter
into the Senior Credit Facility prior to October 1998 with a group of banks
and other financial institutions led by Canadian Imperial Bank of Commerce
(which is an affiliate of CIBC), or one of its affiliates, as agent ("Canadian
Imperial Bank"). None of the elements of the Financing Plan were contingent on
the entering into of the Senior Credit Facility. The following is a summary of
certain expected provisions of the Senior Credit Facility and, therefore, does
not purport to be complete and is subject to, and is qualified in its entirety
by, the final terms of the Senior Credit Facility which may differ from the
provisions described in this summary. In addition, any commitment issued by
Canadian Imperial Bank will be subject to various conditions, and there can be
no assurance that Insight Ohio will be able to enter into a definitive credit
agreement implementing the terms and conditions set forth in the preliminary
statement of terms and conditions provided by Canadian Imperial Bank.
 
  The Senior Credit Facility is expected to provide for revolving credit loans
of $25 million to finance capital expenditures and for working capital and
general purposes, including the upgrade of the System's cable plant and for
the introduction of new video services. The Senior Credit Facility is expected
to have a six-year maturity, with reductions to the amount of the commitment
commencing after three years. The amount available for borrowing is expected
to be reduced by any outstanding letter of credit obligations.
 
  Insight Ohio's obligations under the Senior Credit Facility are expected to
be secured by substantially all the tangible and intangible assets of Insight
Ohio. Loans under the Senior Credit Facility are expected to bear interest, at
Insight Ohio's option, at Canadian Imperial Bank's prime rate or at a
Eurodollar rate. In addition to the index rates, Insight Ohio is expected to
pay an additional margin percentage tied to its ratio of total debt to
adjusted annualized operating cash flow, in the case of prime rate loans,
0.75% or, if under a 5:1 ratio, 0.25%; and in the case of Eurodollar loans,
2.0% or, if under a 5:1 ratio, 1.5%.
 
  The Senior Credit Facility is expected to contain a number of covenants
that, among other things, may restrict the ability of Insight Ohio and its
subsidiaries to make capital expenditures, dispose of assets, incur additional
indebtedness, incur guaranty obligations, pay dividends or make capital
distributions, including distributions on the Preferred Interests that are
required to pay the Notes and the Discount Notes in the event of a payment
default under the Senior Credit Facility, create liens on assets, make
investments, make acquisitions, engage in mergers or consolidations, engage in
certain transactions with subsidiaries and affiliates and otherwise restrict
certain activities. In addition, the Senior Credit Facility is expected to
require compliance with certain financial ratios, including with respect to
total leverage, interest coverage and pro forma debt service coverage.
Management does not expect that such covenants will materially impact the
ability of Insight Ohio to operate its business.
 
  The Senior Credit Facility is expected to contain customary events of
default, including the failure to pay principal when due or any interest or
other amount that becomes due within a period of time after the due date
thereof, any representation or warranty being made by Insight Ohio that is
incorrect in any material respect on or as of the date made, a default in the
performance of any negative covenants or a default in the performance of
certain other covenants or agreements for a specified period, default in
certain other indebtedness, certain insolvency events, certain change of
control events and a default under the Indenture or the Discount Notes
Indenture.
 
DISCOUNT NOTES
 
  Concurrent with the Original Offering, the Discount Notes Issuers offered
$30.0 million gross proceeds ($55,869,000 principal amount at maturity) of the
Discount Notes.
 
  The Discount Notes were issued at a substantial discount to their principal
amount at maturity. A holder of Discount Notes is required to include the
accretion of the original issue discount as gross income for U.S. federal
income tax purposes prior to the receipt of the cash payments to which such
income is attributable.
 
 
                                      77
<PAGE>
 
  Cash interest on the Discount Notes does not accrue and is not payable prior
to August 15, 2003. Thereafter, cash interest on the Discount Notes will
accrue at a rate of 12 7/8% per annum, on the principal amount at maturity of
the Discount Notes, and will be payable semiannually on each February 15 and
August 15, commencing February 15, 2004.
 
  The Discount Notes are joint and several non-recourse obligations of the
Discount Notes Issuers and are secured by a pledge of all of the issued and
outstanding common equity of Coaxial and notes issued by Coaxial DJM LLC and
Coaxial DSM LLC to Coaxial LLC (together, the "LLC Mirror Notes").
 
  The Series B Preferred Interests have an initial liquidation preference of
$30.0 million. All Series B Preferred Interests have been issued to Coaxial;
Insight Ohio will pay distributions to Coaxial in an amount equal to the
interest payments on the Discount Notes. Coaxial will use the distributions
received by it in respect of the Series B Preferred Interests to pay dividends
on its common stock. Pursuant to the LLC Mirror Notes, Coaxial DJM LLC and
Coaxial DSM LLC will pay dividends received by them to Coaxial LLC. Coaxial
LLC will utilize cash dividends from the Coaxial common stock and cash
interest payments from the LLC Mirror Notes to make payments on the Discount
Notes. Neither of the Discount Notes Issuers will conduct any business. The
Series B Preferred Interests will become non-voting upon the enforcement of
remedies under the Discount Notes pledge agreement (as defined in the Discount
Notes Indenture). Though the Series B Preferred Interests will make
distributions in amounts equal to the interest payments on the Discount Notes,
the Series B Preferred Interests will not serve as collateral for the Discount
Notes and the holders of the Discount Notes will not have any direct claim
with respect to the Series B Preferred Interests.
 
  The Series B Preferred Interests are mandatorily redeemable upon
acceleration of indebtedness under the Discount Notes, enforcement of remedies
under the pledge agreement in respect of the Discount Notes collateral, the
passage of ten days and the request by the holders of the Discount Notes. The
Series B Preferred Interests are redeemable at the option of Insight Ohio, so
long as the proceeds thereof are used to make a redemption of the Discount
Notes or an offer to purchase Discount Notes, in each case, in accordance with
the terms of the Discount Notes Indenture. Except for the pledge to the
trustee (as defined in the Discount Notes Indenture) for the benefit of the
holders of the Discount Notes, the exercise of remedies in respect of such
pledge or any transfer after enforcement of such remedies under such pledge,
common stock of Coaxial and the LLC Mirror Notes are non-transferable. The
Series B Preferred Interests are non-transferable.
 
  The Series A Preferred Interests have a priority over the Series B Preferred
Interests with respect to both distributions and redemption.
 
  The Discount Notes are conditionally guaranteed on a senior unsecured basis,
by Insight Ohio and any future Restricted Subsidiaries (other than Coaxial) of
the Discount Notes Issuers (the "Discount Notes Guarantors"). The Discount
Notes Guarantees are only effective to the extent and at the time the holders
of the Discount Notes are unable to realize proceeds from the enforcement of
the mandatory redemption provisions of the Series B Preferred Interests.
Insight Ohio is the only Discount Notes Guarantor currently in existence. The
Discount Notes Guarantees are subordinated to the prior payment in full of all
obligations of the Guarantors with respect to the Guarantees.
 
  The Discount Notes are non-recourse senior obligations of the Discount Notes
Issuers who are not permitted under the Discount Notes Indenture to incur any
other indebtedness. The Discount Notes Guarantees rank pari passu in right of
payment with all existing and future unsubordinated indebtedness of Insight
Ohio and any Restricted Subsidiaries and senior in right of payment to all
existing and future subordinated indebtedness of Insight Ohio and any
restricted subsidiaries (as defined in the Discount Notes Indenture). The
Discount Notes and any Discount Notes Guarantees are effectively subordinated
in right of payment to all secured indebtedness of the Discount Notes
Guarantors to the extent of the value of the assets securing such
indebtedness, including indebtedness under the Senior Credit Facility. In
addition, the Discount Notes are effectively subordinated to all indebtedness
of the Discount Notes Issuers' subsidiaries (including Coaxial) that are not
Discount Notes Guarantors. As of June 30, 1998, after giving pro forma effect
to the Financing Plan, other than the Discount Notes and $140.0 million
represented by the Notes, the Discount Notes Issuers and their Restricted
Subsidiaries
 
                                      78
<PAGE>
 
(presently Coaxial and Insight Ohio) would have had approximately $270,000 of
indebtedness outstanding, all of which would have been secured indebtedness.
 
  The Discount Notes are redeemable at the option of the Discount Notes
Issuers, in whole or in part, at any time on or after August 15, 2003, at the
redemption prices set forth in the Discount Notes Indenture, together with
accrued and unpaid interest thereon, if any, to the redemption date.
 
  Upon a Change of Control (as defined in the Discount Notes Indenture), the
Discount Notes Issuers are required to offer to repurchase all of the
outstanding Discount Notes at a purchase price equal to:
  . 101% of the accreted value (as defined in the Discount Notes Indenture)
    thereof, if the repurchase date is on or prior to August 15, 2003 or
  . 101% of the principal amount at maturity thereof, together with accrued
    and unpaid interest thereon, if any, to the repurchase date, if such date
    is after August 15, 2003.
 
  The Discount Notes Indenture contains covenants that, among other things,
restrict the ability of the Discount Notes Issuers, Insight Ohio and any of
their restricted subsidiaries to:
  . incur additional indebtedness;
  . pay dividends and make distributions;
  . issue stock of subsidiaries to third parties;
  . make certain investments;
  . repurchase stock;
  . create liens;
  . enter into transactions with affiliates;
  . enter into sale and leaseback transactions;
  . create dividend or other payment restrictions affecting restricted
    subsidiaries;
  . merge or consolidate in a transaction involving all or substantially all
    of the assets of the Discount Notes Issuers and their restricted
    subsidiaries, taken as a whole;
  . transfer or sell assets; and
  . use dividends received on the Coaxial common stock and payments received
    in respect of the LLC Mirror Notes for any purpose other than required
    payments of interest and principal on the Discount Notes.
 
  The covenants are subject to a number of important exceptions.
 
  The Discount Notes Issuers are obligated in certain instances to make an
offer to repurchase the Discount Notes at a purchase price equal to (i) 100%
of the accreted value thereof, if the repurchase date is on or prior to August
15, 2003, or (ii) 100% of the principal amount at maturity thereof, together
with accrued and unpaid interest thereon to the purchase date, if the
repurchase date is after August 15, 2003 with the net cash proceeds of certain
asset sales.
 
  The Discount Notes Issuers are obligated in certain instances to make an
offer to repurchase the Discount Notes, at the redemption prices set forth in
the Discount Notes Indenture, plus accrued and unpaid interest, if any, to the
redemption date in connection with certain asset swaps.
 
  Pursuant to the Discount Notes registration rights agreement (as defined in
the Discount Notes Indenture), the Discount Notes Issuers and any Discount
Notes Guarantors must use their reasonable best efforts to file by October 20,
1998, and use their best efforts to cause to become effective by January 18,
1999 an exchange offer registration statement (as defined in the Discount
Notes Indenture) with respect to an offer to exchange the Discount Notes (the
"Discount Notes Exchange Offer") for notes of the Discount Notes Issuers with
terms substantially identical to the Discount Notes (the "Exchange Discount
Notes"). In addition, under certain circumstances the Discount Notes Issuers
and any Discount Notes Guarantors may be required to file a shelf registration
statement (as defined in the Discount Notes Indenture). The Exchange Discount
Notes have terms substantially identical to the Discount Notes. In the event
that certain covenants contained in the Discount Notes registration rights
agreement are not complied with, the Discount Notes Issuers will be required
to pay liquidated damages.

<PAGE>
 
                           DESCRIPTION OF THE NOTES
 
  The Original Notes were, and the Exchange Notes will be, issued under an
Indenture, dated as of August 21, 1998 (the "Indenture") by and among the
Issuers, Insight Ohio and Bank of Montreal Trust Company, as trustee (the
"Trustee"). 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 (the "TIA") as in effect on the date of the Indenture. The
Notes are subject to all such terms, and holders of the Notes are referred to
the Indenture and the TIA for a statement of them. The following is a summary
of the material terms and provisions of the Notes. This summary does not
purport to be a complete description of the Notes and is subject to the
detailed provisions of, and qualified in its entirety by reference to, the
Notes and the Indenture (including the definitions contained in the
Indenture). A copy of the Indenture will be provided without charge upon
request of the Issuers to each person to whom a copy of this Prospectus is
delivered. Definitions relating to certain capitalized terms are set forth
under "--Certain Definitions." Capitalized terms that are used but not
otherwise defined in this Prospectus have the meanings ascribed to them in the
Indenture and such definitions are incorporated in this Prospectus by
reference.
 
GENERAL
 
  The Original Notes initially issued under the Indenture were limited in
aggregate principal amount to $140,000,000. The Notes are senior obligations
of the Issuers, who are not permitted under the Indenture to incur any other
Indebtedness. The Notes are non-recourse obligations of the Issuers and the
only recourse a holder of the Notes has with respect to the payment of
principal or interest on the Notes is the enforcement of the rights granted
pursuant to the Pledge Agreement with respect to the Senior Notes Collateral
(which will require mandatory redemption of the Series A Preferred Interests)
and, failing that, enforcement of the Guarantee. See "Risk Factors--Non-
Recourse Debt; Ability to Realize on Collateral."
 
GUARANTEES
 
  The Notes are conditionally guaranteed, on a senior unsecured basis, by
Insight Ohio and by any future Restricted Subsidiaries of the Issuers. The
conditional Guarantee will become effective upon (i) enforcement by the
Trustee of the rights granted pursuant to the Pledge Agreement with respect to
the Senior Notes Collateral, (ii) Insight Ohio's failure to redeem the Series
A Preferred Interests after ten days as provided in the Operating Agreement
and (iii) an adjudication is obtained relating to such failure. Insight Ohio
is currently the only Guarantor in existence. The Guarantee of any Guarantor
is subordinate to any secured Indebtedness of such Guarantor to the extent of
the assets securing such Indebtedness.
 
  The obligations of each Guarantor are limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of such
Guarantor 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 the Indenture, result in the obligations of such Guarantor
under the Guarantee not constituting a fraudulent conveyance or fraudulent
transfer under federal or state law. Each Guarantor that makes a payment or
distribution under a Guarantee shall be entitled to a contribution from each
other Guarantor in a pro rata amount based on the Adjusted Net Assets of each
Guarantor.
 
  A Guarantor shall be released from all of its obligations under its
Guarantee if all of its assets or Capital Stock is sold, in each case in a
transaction in compliance with "--Certain Covenants--Limitation on Certain
Asset Sales" below, or the Guarantor merges with or into or consolidates with,
or transfers all or substantially
 
                                      80
<PAGE>
 
all of its assets in compliance with "--Merger, Consolidation or Sale of
Assets" below, and such Guarantor has delivered to the Trustee an Officers'
Certificate and an opinion of counsel, each stating that all conditions
precedent herein provided for relating to such transaction have been complied
with.
 
SECURITY
 
  Pursuant to the Pledge Agreement among Coaxial and the Trustee, Coaxial
pledged to the Trustee, for the benefit of the holders of the Notes, the
Series A Preferred Interests in Insight Ohio owned by Coaxial on the Issue
Date or so acquired by Coaxial thereafter all of which constitutes the Senior
Notes Collateral. Such pledge secures the payment and performance when due of
all the obligations of the Issuers under the Indenture and the Notes.
 
  So long as no Event of Default occurs and is continuing, and subject to
certain terms and conditions in the Indenture, Coaxial is entitled to receive
all cash distributions made upon or with respect to the Senior Notes
Collateral pledged by it.
 
  Upon the occurrence and during the continuance of an Event of Default, the
Trustee shall enforce its remedies with respect to the pledged Senior Notes
Collateral in accordance with instructions received from holders of a majority
of the aggregate principal amount at maturity of outstanding Notes, or in the
absence of such instructions, in such manner as the Trustee deems appropriate,
in each case as provided in the Indenture. The Series A Preferred Interests
are mandatorily redeemable ten days after acceleration or such enforcement.
All funds received by the Trustee upon any such enforcement shall be
distributed by the Trustee in accordance with the provisions of the Indenture.
Upon the full and final payment and performance of all obligations of the
Issuers under the Indenture and the Notes, the Senior Notes Collateral shall
be released.
 
  The rights of the Trustee to foreclose upon and dispose of the Senior Notes
Collateral is likely to be significantly impaired by applicable bankruptcy law
if a bankruptcy proceeding were to be commenced by or against the Issuers
prior to the Trustee's having disposed of the Senior Notes Collateral. Under
Title XI of the United States Code (the "Bankruptcy Code"), a secured creditor
such as the Trustee is prohibited from disposing of security upon foreclosure
in a bankruptcy case, even though the debtor is in default under the
applicable debt instruments, without bankruptcy court approval. Moreover, in
general, the Bankruptcy Code prohibits the bankruptcy court from giving such
approval if the secured creditor is given "adequate protection." The meaning
of the term "adequate protection" may vary according to circumstances, but it
is intended in general to protect the value of the secured creditor's interest
in the collateral and may include cash payments or the granting of additional
security, if and at such times as the court in its discretion determines, for
any diminution in the value of the collateral as a result of the stay of
disposition during the pendency of the bankruptcy case. In view of the lack of
a precise definition of the term "adequate protection" and the broad
discretionary powers of a bankruptcy court, it is impossible to predict how
long payments under the Notes could be delayed following commencement of a
bankruptcy case, whether or when the Trustee could dispose of the Senior Notes
Collateral or whether or to what extent holders of the Notes would be
compensated for any delay in payment or loss of value of the pledged
collateral through the requirement of "adequate protection." See "Risk
Factors--Certain Bankruptcy Considerations."
 
MATURITY, INTEREST AND PRINCIPAL
 
  The Notes mature on August 15, 2006. The Notes bear interest at a rate of
10% per annum from the Issue Date until maturity. Interest is payable semi-
annually in arrears on each February 15 and August 15, commencing February 15,
1999, to holders of record of the Notes at the close of business on the
immediately preceding February 1 and August 1, respectively. The interest rate
on the Notes is subject to increase, and such Additional Interest will be
payable on the payment dates set forth above, in certain circumstances, if the
Notes (or other securities substantially similar to the Notes) are not
registered with the SEC within the prescribed time periods. See "The Exchange
Offer--Purpose and Effect of the Exchange Offer."
 
                                      81

OPTIONAL REDEMPTION
 
  The Notes are redeemable at the option of the Issuers, in whole at any time
or in part from time to time on or after August 15, 2002 at the following
redemption prices (expressed as percentages of the principal amount thereof),
together, in each case, with accrued and unpaid interest, if any, to the
redemption date, if redeemed during the twelve-month period beginning on
August 15 of each year listed below:
 
<TABLE>
<CAPTION>
           YEAR                                    PERCENTAGE
           ----                                    ----------
           <S>                                     <C>

           2005 and thereafter....................  100.000%
</TABLE>
 
  Notwithstanding the foregoing, the Issuers may redeem in the aggregate up to
35% of the original principal amount of Notes at any time and from time to
time prior to August 15, 2001 at a redemption price equal to 110% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest, if
any, to the redemption date out of the Net Proceeds of one or more Equity
Offerings; provided that at least $91.0 million of the principal amount of
Notes remain outstanding immediately after the occurrence of any such
redemption and that any such redemption occurs within 90 days following the
closing of any such Equity Offering.
 
  In the event of a redemption of fewer than all of the Notes, the Trustee
shall select the Notes to be redeemed in compliance with the requirements of
the principal national securities exchange, if any, on which such Notes are
listed, or if such Notes are not then listed on a national securities
exchange, on a pro rata basis, by lot or in such other manner as the Trustee
shall deem fair and equitable. The Notes will be redeemable in whole or in
part upon not less than 30 nor more than 60 days' prior written notice, mailed
by first class mail to a holder's last address as it shall appear on the
register maintained by the Registrar of the Notes. On and after any redemption
date, interest will cease to accrue on the Notes or portions thereof called
for redemption as long as funds are deposited with the Paying Agent.
 
CERTAIN COVENANTS
 
  The Indenture contains, among others, the following covenants:
 
 Limitation on Additional Indebtedness
 
  The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, directly or indirectly, incur (as defined) any Indebtedness
(including Acquired 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 such Indebtedness, Insight Ohio or any of the Issuers'
Restricted Subsidiaries may incur Indebtedness (including Acquired
Indebtedness) if after giving effect to the incurrence of such Indebtedness
and the receipt and application of the proceeds thereof, the Consolidated
Leverage Ratio of the Issuers is less than 7 to 1.
 
  Notwithstanding the foregoing, Insight Ohio and the Issuers' Restricted
Subsidiaries may incur Permitted Indebtedness; provided that such Person will
not incur any Permitted Indebtedness that ranks junior in right of payment to
the Notes that has a maturity or mandatory sinking fund payment prior to the
maturity of the Notes.
 
  The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, incur any Indebtedness which by its terms (or by the terms of
any agreement governing such Indebtedness) is subordinated in right of payment
to any other Indebtedness of the Issuers or such Restricted Subsidiary unless
such Indebtedness is also by its terms (or by the terms of any agreement
governing such Indebtedness) made expressly subordinate in right of payment to
the Notes or the Guarantee of such Guarantor, as the case may be, pursuant to
subordination provisions that are substantively identical to the subordination
provisions of such Indebtedness (or such
 
                                      82
<PAGE>
 
agreement) that are most favorable to the holders of any other Indebtedness of
the Issuers or such Restricted Subsidiary, as the case may be.
 
  For purposes of determining compliance with this covenant, in the event that
an item of Indebtedness meets the criteria of more than one of the categories
of Permitted Indebtedness or is entitled to be incurred pursuant to the first
paragraph of this covenant, the Issuers shall, in their sole discretion,
classify such item of Indebtedness in any manner that complies with this
covenant and such item of Indebtedness shall be treated as having been
incurred pursuant to only one of such clauses or pursuant to the first
paragraph hereof.
 
 Limitation on Restricted Payments
 
  The Issuers will not make, and will not permit any of their Restricted
Subsidiaries to, directly or indirectly, make, any Restricted Payment, unless:
 
    (a) no Default or Event of Default shall have occurred and be continuing
  at the time of or immediately after giving effect to such Restricted
  Payment;
 
    (b) immediately after giving pro forma effect to such Restricted Payment,
  Insight Ohio and the Issuers' Restricted Subsidiaries could incur $1.00 of
  additional Indebtedness (other than Permitted Indebtedness) under "--
  Limitation on Additional Indebtedness" above; and
 
    (c) immediately after giving effect to such Restricted Payment, the
  aggregate of all Restricted Payments declared or made after the Issue Date
  does not exceed the sum of:
 
      (1) 100% of the Issuers' Cumulative EBITDA minus 1.4 times the
    Cumulative Consolidated Interest Expense of the Issuers;
 
      (2) 100% of the aggregate Net Proceeds received by an Issuer from the
    issue or sale after the Issue Date of Capital Stock (other than
    Disqualified Capital Stock or Capital Stock of an Issuer issued to any
    Subsidiary of an Issuer) of an Issuer or any Indebtedness or other
    securities of an Issuer convertible into or exercisable or exchangeable
    for Capital Stock (other than Disqualified Capital Stock) of an Issuer
    which has been so converted, exercised or exchanged, as the case may
    be;
 
      (3) without duplication of any amounts included in clause (c)(2)
    above, 100% of the aggregate Net Proceeds received by an Issuer from
    any equity contribution from a holder of an Issuer's Capital Stock,
    excluding, in the case of clauses (c)(2) and (3), any Net Proceeds from
    an Equity Offering to the extent used to redeem the Notes;
 
      (4) in the case of the disposition or repayment of any Investment
    constituting a Restricted Payment made after the Issue Date, an amount
    (to the extent not included in the computation of Consolidated Net
    Income) equal to the lesser of: (x) the return of capital with respect
    to such Investment and (y) the amount of such Investment which was
    treated as a Restricted Payment, in either case, less the cost of the
    disposition of such Investment; and
 
      (5) so long as the Designation Amount thereof was treated as a
    Restricted Payment made after the Issue Date, with respect to any
    Unrestricted Subsidiary that has been redesignated as a Restricted
    Subsidiary after the Issue Date in accordance with the provisions of
    the Indenture, an Issuer's proportionate interest in an amount equal to
    the excess of (x) the total assets of such Subsidiary, valued on an
    aggregate basis at fair market value, over (y) the total liabilities of
    such Subsidiary, determined in accordance with GAAP (and provided that
    such amount shall not in any case exceed the Designation Amount with
    respect to such Restricted Subsidiary upon its Designation).
 
  For purposes of determining under this clause (c) the amount expended for
Restricted Payments, cash distributed shall be valued at the face amount
thereof and property other than cash shall be valued at its fair market value.
 
  The provisions of this covenant shall not prohibit:
 
    (i) the payment of any distribution within 60 days after the date of
  declaration thereof, if at such date of declaration such payment would
  comply with the provisions of the Indenture;
 
                                      83
<PAGE>
 
    (ii) the repurchase, redemption or other acquisition or retirement of any
  shares of Capital Stock of an Issuer or Indebtedness subordinated to the
  Notes by conversion into, or by or in exchange for, shares of Capital Stock
  of an Issuer (other than Disqualified Capital Stock), or out of the Net
  Proceeds of the substantially concurrent sale (other than to a Subsidiary
  of an Issuer) of other shares of Capital Stock of an Issuer (other than
  Disqualified Capital Stock); provided, however, that any such Net Proceeds
  or the value of any Capital Stock issued in exchange for such shares or
  Indebtedness are excluded from clause (c)(2) above (and were not included
  therein at any time);
 
    (iii) the redemption or retirement of Indebtedness of an Issuer
  subordinated to the Notes in exchange for, by conversion into, or out of
  the Net Proceeds of, a substantially concurrent sale or incurrence of
  Indebtedness of an Issuer (other than any Indebtedness owed to a
  Subsidiary) that is contractually subordinated in right of payment to the
  Notes to at least the same extent as the Indebtedness being redeemed or
  retired;
 
    (iv) the retirement of any shares of Disqualified Capital Stock of an
  Issuer by conversion into, or by exchange for, shares of Disqualified
  Capital Stock of an Issuer, or out of the Net Proceeds of the substantially
  concurrent sale (other than to a Subsidiary of an Issuer) of other shares
  of Disqualified Capital Stock of an Issuer; provided, however, that any
  such Net Proceeds or the value of any Capital Stock issued in exchange for
  such shares are excluded from clause (c)(2) above (and were not included
  therein at any time);
 
    (v) whether or not a Default or Event of Default shall have occurred and
  be continuing or occur immediately after giving effect thereto (x)
  Preferred Payments from Insight Ohio and (y) Pass Through Dividends by
  Coaxial;
 
    (vi) except if a default or Event of Default shall have occurred and be
  continuing, Tax Distributions;
 
    (vii) management fees and reimbursement of expenses payable to Insight
  pursuant to the Operating Agreement provided that (i) the Issuers and their
  Restricted Subsidiaries could incur at least $1.00 of additional
  Indebtedness (other than Permitted Indebtedness) under "--Certain
  Covenants--Limitation on Additional Indebtedness" and (ii) no default or
  Event of Default shall have occurred and be continuing in the case of both
  clauses (i) and (ii) of this clause (vii) at (x) the time of payment of
  such management fee and (y) at the Reported Period;
 
    (viii) the purchase of Discount Notes pursuant to "Limitation on Certain
  Asset Sales" and "Change of Control Offer" provisions of the Discount Notes
  Indenture; and
 
    (ix) the distribution by Phoenix of any of the Excluded Assets; provided
  that in calculating the aggregate amount of Restricted Payments made
  subsequent to the Issue Date for purposes of clause (c) of the immediately
  preceding paragraph, amounts expended pursuant to clauses (i), (vi) and
  (viii) shall be included in such calculation.
 
 Limitation on Liens
 
  The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, create, incur or otherwise cause or suffer to exist or become
effective any Liens of any kind (other than Permitted Liens) upon any property
or asset of an Issuer or any of their Restricted Subsidiaries or any shares of
Capital Stock or Indebtedness of any Restricted Subsidiary of an Issuer which
owns property or assets, now owned or hereafter acquired, unless:
 
  . if such Lien secures Indebtedness which is pari passu with the Notes
   (without giving effect to the principles of structural subordination),
   then the Notes are secured on an equal and ratable basis with the
   obligations so secured until such time as such obligation is no longer
   secured by a Lien or
 
  . if such Lien secures Indebtedness which is subordinated to any debt of a
   Restricted Subsidiary, any such Lien shall be subordinated to the Lien
   granted to the holders of the Notes to the same extent as such
   Indebtedness is subordinated to the Notes.
 
                                      84

 Limitation on Transactions with Affiliates
 
  The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, directly or indirectly, enter into or suffer to exist any
transaction or series of related transactions (including, without limitation,
the sale, purchase, exchange or lease of assets, property or services) with
any Affiliate (each an "Affiliate Transaction") or extend, renew, waive or
otherwise modify in any material respect the terms of any Affiliate
Transaction entered into prior to the Issue Date unless:
 
    (i) such Affiliate Transaction is between or among the Issuers, or an
  Issuer and a Restricted Subsidiary of an Issuer; or
 
    (ii) the terms of such Affiliate Transaction are fair and reasonable to
  an Issuer or such Restricted Subsidiary, as the case may be, and the terms
  of such Affiliate Transaction are substantially similar to the terms which
  could reasonably be expected to be obtained by an Issuer or such Restricted
  Subsidiary, as the case may be, in a comparable transaction made on an
  arm's-length basis between unaffiliated parties.
 
  In any Affiliate Transaction (or any series of related Affiliate
Transactions which are similar or part of a common plan) involving an amount
or having a fair market value in excess of $3.0 million which is not permitted
under clause (i) above, an Issuer must obtain a resolution of the Board of
Directors of such Issuer certifying that such Affiliate Transaction complies
with clause (ii) above. In any Affiliate Transaction (or any series of related
Affiliate Transactions which are similar or part of a common plan) involving
an amount or having a fair market value in excess of $5.0 million which is not
permitted under clause (i) above, the Issuers must obtain a favorable written
opinion as to the fairness, from a financial point of view, of such
transaction or transactions, as the case may be, from an Independent Financial
Advisor.
 
  The foregoing provisions will not apply to:
 
  . any Restricted Payment that is not prohibited by the provisions described
   under "--Limitation on Restricted Payments" above;
 
  . reasonable fees and compensation paid to and indemnity provided on behalf
   of, officers, directors or employees of the Issuers or any Restricted
   Subsidiary of an Issuer as determined in good faith by the Issuer's Board
   of Directors or senior management;
 
  . arrangements now or hereafter in effect between Insight and third parties
   which arrangements can be used for the benefit of a Restricted Subsidiary;
   and
 
  . any forgiveness or distribution by Phoenix of the Excluded Assets.
 
  Notwithstanding anything contained in this Prospectus to the contrary, the
terms of the Operating Agreement and the indemnification provisions of the
Close Corporation Agreement and the performance by any party thereto of its
obligations thereunder shall not be considered an Affiliate Transaction.
 
 Limitation on Creation of Subsidiaries
 
  The Issuers will not create or acquire, and will not permit any of their
Restricted Subsidiaries to create or acquire, any Subsidiary other than:
 
    (i) a Restricted Subsidiary existing as of the Issue Date; or
 
    (ii) a Restricted Subsidiary that is acquired or created in connection
  with the acquisition by an Issuer of a related business or asset; or
 
    (iii) an Unrestricted Subsidiary;
 
provided, however, that each Restricted Subsidiary acquired or created
pursuant to clause (ii) shall have executed a guarantee, satisfactory in form
and substance to the Trustee (and with such documentation relating thereto as
the Trustee shall require, including, without limitation a supplement or
amendment to the Indenture and opinions of counsel as to the enforceability of
such guarantee), pursuant to which such Restricted Subsidiary will become a
Guarantor. As of the Issue Date, the Issuers had no Restricted Subsidiaries,
other than Insight Ohio. See "--General."

 Limitation on Certain Asset Sales
 
  The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, consummate an Asset Sale unless:
 
    (i) the Issuer or such applicable Restricted Subsidiary, as the case may
  be, receives consideration at the time of such sale or other disposition at
  least equal to the fair market value of the assets sold or otherwise
  disposed of;
 
    (ii) not less than 80% of the consideration received by an Issuer or such
  applicable Restricted Subsidiary, as the case may be, is in the form of
  cash or Cash Equivalents; provided, however, that the amount of any (x)
  Indebtedness of an Issuer or any Restricted Subsidiary that is actually
  assumed by the transferee in such Asset Sale and from which an Issuer and
  the Restricted Subsidiaries are fully released shall be deemed to be cash
  for purposes of determining the percentage of cash consideration received
  by an Issuer or the Restricted Subsidiaries and (y) notes or other similar
  obligations received by an Issuer or the Restricted Subsidiaries from such
  transferee that are immediately converted, sold or exchanged (or are
  converted, sold or exchanged within 30 days of the related Asset Sale) by
  an Issuer or the Restricted Subsidiaries into cash shall be deemed to be
  cash, in an amount equal to the net cash proceeds realized upon such
  conversion, sale or exchange for purposes of determining the percentage of
  cash consideration received by an Issuer or the Restricted Subsidiaries;
  and
 
    (iii) the Asset Sale Proceeds received by an Issuer or such Restricted
  Subsidiary are applied:
 
      (a) to the extent an Issuer or any such Restricted Subsidiary, as the
    case may be, elects, or is required, to prepay, repay or purchase
    indebtedness under the Senior Credit Facility within 180 days following
    the receipt of the Asset Sale Proceeds from any Asset Sale; provided
    that any such repayment shall result in a permanent reduction of the
    commitments thereunder (other than commitments under a revolving credit
    facility) in an amount equal to the principal amount so repaid; or
 
      (b) to the extent of the balance of Asset Sale Proceeds, after
    application, if any, as described above, to the extent the Issuers
    elect, on a pro rata basis to the repayment of an amount of Other Pari
    Passu Debt not exceeding the Other Pari Passu Debt Pro Rata Share
    (provided that any such repayment shall result in a permanent reduction
    of any commitment in respect thereof in an amount equal to the
    principal amount so repaid) within 180 days following the receipt of
    the Asset Sale Proceeds from any Asset Sale; or
 
      (c) to the extent of the balance of Asset Sale Proceeds after
    application as described above, to the extent the Issuers or a
    Restricted Subsidiary elect, to an investment in assets (including
    Capital Stock or other securities purchased in connection with the
    acquisition of Capital Stock or property of another Person) used or
    useful in businesses similar, ancillary, complementary or otherwise
    related to the business of an Issuer or any such Restricted Subsidiary
    as then conducted; provided that (1) such investment occurs or an
    Issuer or any such Restricted Subsidiary enters into contractual
    commitments to make such investment, subject only to customary
    conditions (other than the obtaining of financing), within 180 days
    following receipt of such Asset Sale Proceeds and (2) Asset Sale
    Proceeds so contractually committed are so applied within 270 days
    following the receipt of such Asset Sale Proceeds; and
 
      (d) if on such 180th day in the case of clauses (iii)(a), (iii)(b)
    and (iii)(c)(1) or on such 270th day in the case of clause (iii)(c)(2)
    with respect to any Asset Sale, the Available Asset Sale Proceeds
    exceed $10.0 million, the Issuers shall apply an amount equal to the
    Available Asset Sale Proceeds to an offer to repurchase the Notes, at a
    purchase price in cash equal to 100% of the principal amount thereof
    plus accrued and unpaid interest, if any, to the purchase date (an
    "Excess Proceeds Offer").
 
  If an Excess Proceeds Offer is not fully subscribed, the Issuers may retain
the portion of the Available Asset Sale Proceeds not required to repurchase
Notes.
 
                                      86
<PAGE>
 
  If the Issuers are required to make an Excess Proceeds Offer, the Issuers
shall mail, within 30 days following the date specified in clause (iii)(d)
above, a notice to the holders stating, among other things:
 
  . that such holders have the right to require the Issuers to apply the
    Available Asset Sale Proceeds to repurchase such Notes at a purchase
    price in cash equal to 100% of the principal amount thereof plus accrued
    and unpaid interest, if any, to the purchase date;
 
  . the purchase date, which shall be no earlier than 30 days and not later
    than 45 days from the date such notice is mailed;
 
  . the instructions that each holder must follow in order to have such Notes
    purchased; and
 
  . the calculations used in determining the amount of Available Asset Sale
    Proceeds to be applied to the purchase of such Notes.
 
  In the event of the transfer of substantially all of the property and assets
of the Issuers and their Restricted Subsidiaries as an entirety to a Person in
a transaction permitted under "--Merger, Consolidation or Sale of Assets"
below, the successor Person shall be deemed to have sold the properties and
assets of the Issuers and their Restricted Subsidiaries not so transferred for
purposes of this covenant, and shall comply with the provisions of this
covenant with respect to such deemed sale as if it were an Asset Sale.
 
  The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to an Excess Proceeds Offer. To the extent that
the provisions of any securities laws or regulations conflict with the "Asset
Sale" provisions of the Indenture, the Issuers shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached their obligations under the "Asset Sale" provisions of the Indenture
by virtue thereof.
 
 Limitation on Asset Swaps
 
  The Issuers will not, and will not permit any Restricted Subsidiary to,
engage in any Asset Swaps which constitutes substantially all of the assets of
the Issuers, unless:
 
    (i) at the time of entering into the agreement to swap assets and
  immediately after giving effect to the proposed Asset Swap, no default or
  Event of Default shall have occurred and be continuing or would occur as a
  consequence thereof; and
 
    (ii) the Issuers have been informed in writing by either S&P or Moody's
  that any Indebtedness of the Issuers (including the Notes) will not be
  downgraded as a result of such Asset Swap.
 
  Notwithstanding clause (ii) of the immediately preceding sentence, the
Issuers will be allowed to consummate an Asset Swap even if such Asset Swap
will result in such a downgrade, if within five days of the occurrence of such
Asset Swap, the Issuers make an offer to purchase Notes in accordance with the
procedures described in "--Change of Control Offer" (the "Asset Swap Offer")
at the following redemption prices (expressed as percentages of the principal
amount thereof) not less than 103.000% together, in each case, with accrued
and unpaid interest, if any, to the redemption date, if redeemed during the
twelve-month period beginning on August 15 of each year listed below:

  The Issuers will not engage in any business other than holding common
membership interests and the Preferred Interests of Insight Ohio and issuing
the Notes and, in the case of Phoenix, holding the Excluded Assets. The

directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any holder of any 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 such consideration is offered

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

  covenant and that all Notes tendered will be accepted for payment;
 
 
                                      89
<PAGE>
 
    (2) the Change of Control Purchase Price and the purchase date (which
  shall be a Business Day no earlier than 30 days nor later than 45 days from
  the date such notice is mailed (the "Change of Control Payment Date"));
 
    (3) that any Note not tendered will continue to accrue interest;
 
    (4) that, unless the Issuers default in the payment of the Change of
  Control Purchase Price, any Notes accepted for payment pursuant to the
  Change of Control Offer shall cease to accrue interest after the Change of
  Control Payment Date;
 
    (5) that holders accepting the offer to have their Notes purchased
  pursuant to a Change of Control Offer will be required to surrender the
  Notes to the Paying Agent at the address specified in the notice prior to
  the close of business on the Business Day preceding the Change of Control
  Payment Date;
 
    (6) that holders will be entitled to withdraw their acceptance if the
  Paying Agent receives, not later than the close of business on the third
  Business Day preceding 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 Notes delivered for purchase, and a
  statement that such holder is withdrawing his election to have such Notes
  purchased;
 
    (7) that holders whose Notes are being purchased only in part will be
  issued new Notes equal in principal amount to the unpurchased portion of
  the Senior Notes surrendered;
 
    (8) any other procedures that a holder must follow to accept a Change of
  Control Offer or effect withdrawal of such acceptance; and
 
    (9) the name and address of the Paying Agent.
 
  On the Change of Control Payment Date, the Issuers shall, to the extent
lawful, (i) accept for payment Notes or portions thereof tendered pursuant to
the Change of Control Offer, (ii) deposit with the Paying Agent money
sufficient to pay the purchase price of all Notes or portions thereof so
tendered and (iii) deliver or cause to be delivered to the Trustee Notes so
accepted together with an Officers' Certificate stating the Notes or portions
thereof tendered to the Issuers. The Paying Agent shall promptly mail to each
holder of Notes so accepted payment in an amount equal to the purchase price
for such Notes, and the Issuers shall execute and issue, and the Trustee shall
promptly authenticate and mail to such holder, a new note equal in principal
amount to any unpurchased portion of the Notes surrendered; provided that each
such new note shall be issued in an original principal amount in denominations
of $1,000 and integral multiples thereof.
 
  The Indenture requires that if the Senior Credit Facility is in effect, or
any amounts are owing thereunder or in respect thereof, at the time of the
occurrence of a Change of Control, prior to the mailing of the notice to
holders described in the second preceding paragraph, but in any event within
20 days following any Change of Control, the Issuers covenant to (i) repay in
full all obligations and terminate all commitments under or in respect of the
Senior Credit Facility or offer to repay in full all obligations and terminate
all commitments under or in respect of the Senior Credit Facility and repay
the Indebtedness owed to each such lender who has accepted such offer or (ii)
obtain the requisite consents under the Senior Credit Facility to permit the
repurchase of the Notes as described above. The Issuers must first comply with
the covenant described in the preceding sentence before it shall be required
to purchase Notes in the event of a Change of Control; provided that the
Issuers' failure to comply with the covenant described in the preceding
sentence constitutes an Event of Default described in clause (iii) under "--
Events of Default" below if not cured within 30 days after the notice required
by such clause. As a result of the foregoing, a holder of the Notes may not be
able to compel the Issuers to purchase the Notes unless the Issuers are able
at the time to refinance all of the obligations under or in respect of the
Senior Credit Facility or obtain requisite consents under the Senior Credit
Facility.
 
 
                                      90

  The Indenture provides that, (A) if an Issuer or any Restricted Subsidiary
thereof has issued any outstanding (i) indebtedness that is subordinated in
right of payment to the Notes or senior in right of payment with respect to
Indebtedness of Restricted Subsidiaries (other than under the Senior Credit
Facility) or (ii) Preferred Stock, and an Issuer or such Restricted Subsidiary
is required to make a Change of Control Offer or to make a distribution with
respect to such indebtedness or Preferred Stock in the event of a change of
control, the Issuers shall not consummate any such offer or distribution with
respect to such indebtedness or Preferred Stock until such time as the Issuers
shall have paid the Change of Control Purchase Price in full to the holders of
Notes that have accepted the Issuers' change of control offer and shall
otherwise have consummated the change of control offer made to holders of the
Notes and (B) the Issuers will not issue Indebtedness that is subordinated in
right of payment to the Notes or Preferred Stock with change of control
provisions requiring the payment of such Indebtedness or Preferred Stock prior
to the payment of the Notes in the event of a Change in Control under the
Indenture.
 
  The Issuers will not be required to make a Change of Control Offer if a
third party makes the Change of Control Offer in the manner, at the time and
otherwise in compliance with the requirements set forth in the Indenture
applicable to a Change of Control Offer made by the Issuers and purchases all
Notes or portions thereof validly tendered and not withdrawn under such Change
of Control Offer.
 
  If a Change of Control were to occur, the Issuers may not have sufficient
available funds to make the Change of Control Offer for all Notes that might
be delivered by holders of the Notes seeking to accept the Change of Control
Offer. The failure of the Issuers to make or consummate the Change of Control
Offer or to pay the Change of Control Payment when due will give the Trustee
and the holders of the Notes the right described under "Events of Default"
below. See "Risk Factors--Ability to Purchase Notes Upon a Change of Control."
 
  The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such 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 their obligations under the "Change of Control" provisions of the
Indenture by virtue thereof.
 
MERGER, CONSOLIDATION OR SALE OF ASSETS
 
  The Issuers will not and will not permit any of their Restricted
Subsidiaries to consolidate with, merge with or into, or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of
the assets of the Issuers (as an entirety or substantially as an entirety in
one transaction or a series of related transactions), to any Person unless:
(i) an Issuer or such Restricted Subsidiary, as the case may be, shall be the
continuing Person, or the Person (if other than an Issuer or such Restricted
Subsidiary) formed by such consolidation or into which an Issuer or such
Restricted Subsidiary, as the case may be, is merged or to which the
properties and assets of an Issuer or such Restricted Subsidiary, as the case
may be, are sold, assigned, transferred, leased, conveyed or otherwise
disposed of shall be a corporation organized and existing under the laws of
the United States or any State thereof or the District of Columbia and shall
expressly assume, by a supplemental indenture, executed and delivered to the
Trustee, in form satisfactory to the Trustee, all of the obligations of an
Issuer or such Restricted Subsidiary, as the case may be, under the Indenture,
the Notes and the Guarantees, and the obligations thereunder shall remain in
full force and effect; (ii) immediately before and immediately after giving
effect to such transaction, no default or Event of Default shall have occurred
and be continuing; and (iii) immediately after giving effect to such
transaction on a pro forma basis the Issuers or such Person could incur at
least $1.00 of additional Indebtedness (other than Permitted Indebtedness)
under "--Certain Covenants--Limitation on Additional Indebtedness" above;
provided that Insight Ohio may merge with Coaxial without complying with this
clause (iii).
 
                                      91
<PAGE>
 
  In connection with any consolidation, merger or transfer of assets
contemplated by this provision, the Issuers shall deliver, or cause to be
delivered, to the Trustee, in form and substance reasonably satisfactory to
the Trustee, an Officers' Certificate and an opinion of counsel, each stating
that such consolidation, merger or transfer and the supplemental indenture in
respect thereto comply with this provision and that all conditions precedent
herein provided for relating to such transaction or transactions have been
complied with.
 
  For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) 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 Issuers, shall be deemed
to be the transfer of all or substantially all of the properties and assets of
the Issuers.
 
EVENTS OF DEFAULT
 
  The following events are defined in the Indenture as "Events of Default":
 
    (i) default in payment of any principal of, or premium, if any, on the
  Notes whether at maturity, upon redemption or otherwise;
 
    (ii) default for 30 days in payment of any interest on the Notes;
 
    (iii) default by an Issuer or any Restricted Subsidiary in the observance
  or performance of any other covenant in the Notes or the Indenture for 30
  days after written notice from the Trustee as directed by the holders of
  not less than 25% in aggregate principal amount of the Notes then
  outstanding (except in the case of a default with respect to the "Change of
  Control" or "Merger, Consolidation or Sale of Assets" covenant which shall
  constitute an Event of Default with such notice requirement but without
  such passage of time requirement);
 
    (iv) failure to pay when due principal, interest or premium in an
  aggregate amount of $7.5 million or more with respect to any Indebtedness
  of an Issuer or any Restricted Subsidiary thereof, or the acceleration of
  any such Indebtedness aggregating $7.5 million or more which default shall
  not be cured, waived or postponed pursuant to an agreement with the holders
  of such Indebtedness within 60 days after written notice as provided in the
  Indenture, or such acceleration shall not be rescinded or annulled within
  20 days after written notice as provided in the Indenture;
 
    (v) any final judgment or judgments which can no longer be appealed for
  the payment of money in excess of $7.5 million, net of any amounts covered
  by insurance, shall be rendered against an Issuer or any Restricted
  Subsidiary thereof, and shall not be discharged for any period of 60
  consecutive days during which a stay of enforcement shall not be in effect;
 
    (vi) certain events involving bankruptcy, insolvency or reorganization of
  an Issuer or any Restricted Subsidiary thereof;
 
    (vii) any modification of the mandatory redemption provisions relating to
  the Preferred Interests contained in the Operating Agreement;
 
    (viii) any of the Guarantees ceases to be in full force and effect or any
  of the Guarantees is declared to be null and void and unenforceable or any
  of the Guarantees is found to be invalid or any of the Guarantors denies
  its liability under its Guarantee (other than by reason of release of a
  Guarantor in accordance with the terms of the Indenture);
 
    (ix) failure to have a first priority perfected security interest with
  respect to the Senior Notes Collateral; and
 
    (x) the occurrence of an "Event of Default" under the Discount Notes
  Indenture.
 
  The Indenture provides that the Trustee may withhold notice to the holders
of the Notes of any default (except in payment of principal or premium, if
any, or interest on the Notes) if the Trustee considers it to be in the best
interest of the holders of the Notes to do so.
 
                                      92
<PAGE>
 
  The Indenture provides that if an Event of Default (other than an Event of
Default resulting from certain events of bankruptcy, insolvency or
reorganization) shall have occurred and be continuing, then the Trustee or the
holders as directed by not less than 25% in aggregate principal amount of the
Notes then outstanding may declare to be immediately due and payable the
entire principal amount of all the Notes then outstanding plus accrued
interest to the date of acceleration (i) and the same shall become immediately
due and payable or (ii) if there are any amounts outstanding under the Senior
Credit Facility, shall become immediately due and payable upon the first to
occur of an acceleration under the Senior Credit Facility or 5 business days
after receipt by an Issuer and the representative under the Senior Credit
Facility of a notice of acceleration; provided, however, that after such
acceleration but before a judgment or decree based on acceleration is obtained
by the Trustee, the holders of a majority in aggregate principal amount of
outstanding Notes may, under certain circumstances, rescind and annul such
acceleration if (i) all Events of Default, other than nonpayment of principal,
premium, if any, or interest that has become due solely because of the
acceleration, have been cured or waived as provided in the Indenture, (ii) 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, (iii) if the Issuers
have paid the Trustee its reasonable compensation and reimbursed the Trustee
for its expenses, disbursements and advances and (iv) in the event of the cure
or waiver of an Event of Default of the type described in clause (vi) of the
above Events of Default, the Trustee shall have received an Officers'
Certificate 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. In case an Event of Default resulting
from certain events of bankruptcy, insolvency or reorganization shall occur,
the principal, premium and interest amount with respect to all of the Notes
shall be due and payable immediately without any declaration or other act on
the part of the Trustee or the holders of the Notes.
 
  The holders of a majority in principal amount of the Notes then outstanding
shall have the right to waive any existing default or compliance with any
provision of the Notes Indenture or the Notes and to direct the time, method
and place of conducting any proceeding for any remedy available to the
Trustee, subject to certain limitations provided for in the Indenture and
under the TIA.
 
  No holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such holder
shall have previously given to the Trustee written notice of a continuing
Event of Default and unless the holders of at least 25% in aggregate principal
amount of the outstanding Notes shall have made written request and offered
reasonable indemnity to the Trustee to institute such proceeding as Trustee,
and unless the Trustee shall not have received from the holders of a majority
in aggregate principal amount of the outstanding Notes a direction
inconsistent with such request and shall have failed to institute such
proceeding within 60 days. Notwithstanding the foregoing, such limitations do
not apply to a suit instituted on such Note on or after the respective due
dates expressed in such Note.
 
DEFEASANCE AND COVENANT DEFEASANCE
 
  The Indenture provides that the Issuers may elect either (a) to defease and
be discharged from any and all of their and any Guarantor's obligations with
respect to the Notes (except for the obligations to register the transfer or
exchange of such Notes, to replace temporary or mutilated, destroyed, lost or
stolen Notes, to maintain an office or agency in respect of the Notes and to
hold monies for payment in trust) ("defeasance") or (b) to be released from
their obligations with respect to the Notes under certain covenants contained
in the Indenture ("covenant defeasance") upon the deposit with the Trustee (or
other qualifying trustee), in trust for such purpose, of money and/or non-
callable U.S. government obligations which through the payment of principal
and interest in accordance with their terms will provide money, in an amount
sufficient to pay the principal of, premium, if any, and interest on the
Notes, on the scheduled due dates therefor or on a selected date of redemption
in accordance with the terms of the Indenture. Such a trust may only be
established if, among other things:
 
  . the Issuers have delivered to the Trustee an opinion of counsel (as
   specified in the Indenture) (A) to the effect that neither the trust nor
   the Trustee will be required to register as an investment company under
   the Investment Company Act of 1940, as amended, and (B) describing either
   a private ruling concerning
 
                                      93
<PAGE>
 
   the Notes or a published ruling of the Internal Revenue Service, to the
   effect that holders of the Notes or persons in their positions will not
   recognize income, gain or loss for federal income tax purposes as a result
   of such deposit, defeasance and discharge and will be subject to federal
   income tax on the same amount and in the same manner and at the same
   times, as would have been the case if such deposit, defeasance and
   discharge had not occurred;
  . no default or Event of Default shall have occurred and be continuing on
   the date of such deposit or insofar as Events of Default from bankruptcy,
   insolvency or reorganization events are concerned, at any time in the
   period ending on the 91st day after the date of deposit;
  . such defeasance or covenant defeasance shall not result in a breach or
   violation of, or constitute a default under the Indenture or any other
   material agreement or instrument to which an Issuer or any of their
   Subsidiaries is a party or by which an Issuer or any or their Subsidiaries
   is bound;
  . the Issuers 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 of the Notes 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;
  . the Issuers 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 defeasance or the covenant defeasance have
   been complied with;
  . the Issuers shall have delivered to the Trustee an opinion of counsel to
   the effect after the 91st day following the 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
  . certain other customary conditions precedent are satisfied.
 
MODIFICATION OF INDENTURE
 
  From time to time, the Issuers, the Guarantors and the Trustee may, without
the consent of holders of the Notes, amend or supplement the Notes Indenture
for certain specified purposes, including providing for uncertificated Notes
in addition to certificated Notes, and curing any ambiguity, defect or
inconsistency, or making any other change that does not, in the opinion of the
Trustee, materially and adversely affect the rights of any holder. The
Indenture contains provisions permitting the Issuers, the Guarantors and the
Trustee, with the consent of holders of at least a majority in principal
amount of the outstanding Notes, to modify or supplement the Indenture and the
Pledge Agreement, except that no such modification shall, without the consent
of each holder affected thereby:
 
  . reduce the amount of Notes whose holders must consent to an amendment,
   supplement, or waiver to the Indenture;
  . reduce the rate of or change the time for payment of interest, including
   defaulted interest, on any Note;
  . reduce the principal of or premium on or change the stated maturity of
   any Note or change the date on which any Notes may be subject to
   redemption or repurchase or reduce the redemption or repurchase price
   therefor;
  . make any Note payable in money other than that stated in the Note or
   change the place of payment from New York, New York;
  . waive a default on the payment of the principal of, interest on, or
   redemption payment with respect to any Note;
  . make any change in provisions of the Indenture protecting the right of
   each holder of Notes 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, or permitting holders of a majority in principal amount of
   Notes to waive defaults or Events of Default;
  . amend, change or modify in any material respect the obligation of the
   Issuers to make and consummate a Change of Control Offer in the event of a
   Change of Control or make and consummate an Asset Sale Offer with respect
   to any Asset Sale that has been consummated or modify any of the
   provisions or definitions with respect thereto;
 
                                      94
<PAGE>
 
  . modify or change any provision of the Indenture or the related
   definitions affecting the ranking of the Notes or any Guarantee in a
   manner which adversely affects the holders of Notes;
  . release any Guarantor from any of its obligations under its Guarantee or
   the Indenture otherwise than in accordance with the terms of the
   Indenture;
  . modify or waive a default with respect to clause (vii) under "Events of
   Default".
REPORTS TO HOLDERS
 
  So long as the Issuers are subject to the periodic reporting requirements of
the Exchange Act, they will continue to furnish the information required
thereby to the SEC and to the holders of the Notes. The Indenture provides
that even if the Issuers are entitled under the Exchange Act not to furnish
such information to the SEC or to the holders of the Notes, it will
nonetheless continue to furnish such information to the SEC (unless the SEC
does not permit such filing) and holders of the Notes.
 
COMPLIANCE CERTIFICATE
 
  The Issuers will deliver to the Trustee on or before 90 days after the end
of the Notes Issuers' fiscal year an Officers' Certificate stating whether or
not the signers know of any Default or Event of Default that has occurred and
is continuing. If they do, the certificate will describe the Default or Event
of Default, its status and the intended method of cure, if any.
 
THE TRUSTEE
 
  The Trustee under the Indenture is the Registrar and Paying Agent with
regard to the Notes. 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. During the existence of an
Event of Default, the Trustee will exercise such rights and powers vested in
it under the Indenture and use the same degree of care and skill in its
exercise as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.
 
TRANSFER AND EXCHANGE
 
  Holders of the Notes may transfer or exchange Notes in accordance with the
Notes Indenture. The Registrar under the Indenture may require a holder, among
other things, to furnish appropriate endorsements and transfer documents, and
to pay any taxes and fees required by law or permitted by the Indenture. The
Registrar is not required to transfer or exchange any Note selected for
redemption and, further, is not required to transfer or exchange any Note for
a period of 15 days before selection of the Notes to be redeemed.
 
  The Original Notes have been issued in a transaction exempt from
registration under the Securities Act and will be subject to the restrictions
on transfer described in "Notice to Investors."
 
  The registered holder of a Note may be treated as the owner of it for all
purposes.
 
CERTAIN DEFINITIONS
 
  Set forth below is a summary of certain of the defined terms used in the
Indenture. Reference is made to the Indenture for the full definition of all
such terms as well as any other capitalized terms used in this Prospectus for
which no definition is provided.
 
  "Acquired Indebtedness" means Indebtedness of a Person (including an
Unrestricted Subsidiary) existing at the time such Person becomes a Restricted
Subsidiary or is merged into or consolidated with any other Person or which is
assumed in connection with the acquisition of assets from such Person and, in
each case, not incurred by such Person in connection with, or in anticipation
or contemplation of, such Person becoming a Restricted Subsidiary or such
merger, consolidation or acquisition.
 
  "Adjusted Net Assets" of any Person at any date shall mean the lesser of the
amount by which (x) the fair value of the property of such Person exceeds the
total amount of liabilities, including, without limitation, contingent
liabilities (after giving effect to all other fixed and contingent
liabilities), but excluding liabilities under the Guarantee of such Person at
such date and (y) the present fair salable value of the assets of such Person
 
                                      95
<PAGE>
 
at such date exceeds the amount that will be required to pay the probable
liability of such Person on its debts (after giving effect to all other fixed
and contingent liabilities and after giving effect to any collection from any
Subsidiary of such Person in respect of the obligations of such Person under
the Guarantee of such Person), excluding Indebtedness in respect of the
Guarantee of such Person, as they become absolute and matured.
 
  "Affiliate" means, with respect to any specific Person, any other Person
that directly or indirectly through one or more intermediaries controls, or is
controlled by, or is under common control with, such specified Person. For the
purposes of this definition, "control" (including, with correlative meanings,
the terms "controlling," "controlled by," and "under common control with"), as
used with respect to any Person, means the possession, directly or indirectly,
of the power to direct or cause the direction of the management or policies of
such Person, whether through the ownership of voting securities, by agreement
or otherwise; provided that, for purposes of the covenant described under "--
Certain Covenants--Limitation on Transactions with Affiliates" beneficial
ownership of at least 10% of the voting securities of a Person, either
directly or indirectly, shall be deemed to be control.
 
  "Annualized EBITDA" means EBITDA of the Issuers and their Restricted
Subsidiaries for the latest fiscal quarter for which financial statements are
available multiplied by four (such fiscal quarter the "One Quarter Period").
For purposes of this definition, "EBITDA" shall be calculated for any period
after giving effect on a pro forma basis to (i) the incurrence or repayment of
any Indebtedness of such Person 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, occurring during the One
Quarter Period or at any time subsequent to the last day of the One 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 One Quarter Period and (ii) any Asset Sales
or Asset Acquisitions (including, without limitation, any Asset Acquisition
giving rise to the need to make such calculation as a result of such Person or
one of its Restricted Subsidiaries (including any Person who becomes a
Restricted Subsidiary as a result of the Asset Acquisition) incurring,
assuming or otherwise being liable for Acquired Indebtedness and also
including any EBITDA (provided that such EBITDA shall be included only to the
extent includable pursuant to the definition of "Consolidated Net Income")
attributable to the assets which are the subject of the Asset Acquisition or
Asset Sale during the One Quarter Period) occurring during the One Quarter
Period or at any time subsequent to the last day of the One Quarter Period and
on or prior to the Transaction Date, as if such Asset Sale or Asset
Acquisition (including the incurrence, assumption or liability for any such
Acquired Indebtedness) occurred on the first day of the One Quarter Period. If
such Person 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 such Person or
any Restricted Subsidiary or such Person had directly incurred or otherwise
assumed such guaranteed Indebtedness. For purposes of this definition,
whenever pro forma effect is to be given to an Asset Sale or Asset Acquisition
(including pursuant to the System Acquisition), the amount of income or
earnings and any net cost savings relating thereto and the amount of
Consolidated Interest Expense associated with any Indebtedness incurred in
connection therewith, the pro forma calculations shall be determined in
accordance with Regulation S-X under the Securities Act.
 
  "Asset Acquisition" means (a) an Investment by an Issuer or any Restricted
Subsidiary of an Issuer in any other Person pursuant to which such Person
shall become a Restricted Subsidiary of an Issuer or any Restricted Subsidiary
of an Issuer, or shall be merged with or into an Issuer or any Restricted
Subsidiary of an Issuer or (b) the acquisition by an Issuer or any Restricted
Subsidiary of an Issuer of the assets of any Person (other than a Restricted
Subsidiary of an Issuer) which constitute all or substantially all of the
assets of such Person or comprise any division or line of business of such
Person or any other properties or assets of such Person other than in the
ordinary course of business.
 
  "Asset Sale" means any direct or indirect sale, issuance, conveyance,
assignment, transfer, lease or other disposition (excluding Asset Swaps),
other than to an Issuer or any of its Wholly Owned Subsidiaries, in any

<PAGE>
 
single transaction or series of related transactions of (a) any Capital Stock
of or other equity interest in any Restricted Subsidiary of an Issuer or (b)
any other property or assets of an Issuer or of any Restricted Subsidiary
thereof; provided that Asset Sales shall not include (i) a transaction or
series of related transactions for which an Issuer or its Restricted
Subsidiaries receive aggregate consideration of less than $1.5 million, (ii)
the sale, lease, conveyance, disposition or other transfer of all or
substantially all of the assets of an Issuer as permitted under "--Merger,
Consolidation or Sale of Assets," (iii) any transaction consummated in
compliance with the covenant described above under "--Limitation on Restricted
Payments" and (iv) any sale, lease, conveyance, disposition or other transfer
of all or any portion of the Excluded Assets.
 
  "Asset Sale Proceeds" means, with respect to any Asset Sale, (i) cash
received by an Issuer or any Restricted Subsidiary of an Issuer from such
Asset Sale (including cash received as consideration for the assumption of
liabilities incurred in connection with or in anticipation of such Asset
Sale), after (a) provision for all income or other taxes measured by or
resulting from such Asset Sale, (b) payment of all brokerage commissions,
underwriting and other fees and expenses related to such Asset Sale, (c)

<PAGE>
 
                         BOOK-ENTRY; DELIVERY AND FORM
 
  The Original Notes were offered and sold in connection with the Original
Notes Offering solely to "qualified institutional buyers," as defined in Rule
144A under the Securities Act ("QIBs"), pursuant to Rule 144A and in offshore
transactions to persons other than "U.S. persons", as defined in Regulation S
under the Securities Act ("Non-U.S. Persons"), in reliance on Regulation S.
 
THE GLOBAL NOTES
 
  Except as described below, the Exchange Notes initially will be represented
by permanent global certificates in definitive, fully registered form (the
"Global Notes"). The Global Notes will be deposited on the Exchange Date with,
or on behalf of, The Depository Trust Company ("DTC") and registered in the
name of Cede & Co., as nominee of DTC, or will remain in the custody of the
Trustee pursuant to the FAST Balance Certificate Agreement between DTC and the
Trustee.
 
  All interests in the Global Notes, including those held through Morgan
Guaranty Trust Company of New York, Brussels Office, as operator of the
Euroclear System ("Euroclear"), or Cedel Bank, societe anonyme ("Cedel"), may
be subject to the procedures and requirements of DTC. Those interests held
through Euroclear or Cedel may also be subject to the procedures and
requirements of such systems.
 
  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 such Global Note and become an
interest in the other Global Note and, accordingly, will thereafter be subject
to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such
an interest.
 
CERTAIN BOOK-ENTRY PROCEDURES FOR THE GLOBAL NOTES
 
  The descriptions of the operations and procedures of DTC, Euroclear and
Cedel 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 the Issuers nor CIBC 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 the Issuers that it is (i) a limited purpose trust company
organized under the laws of the State of New York, (ii) a "banking
organization" within the meaning of the New York Banking Law, (iii) a member
of the Federal Reserve System, (iv) a "clearing corporation" within the
meaning of the Uniform Commercial Code, as amended, and (v) a "clearing
agency" registered pursuant to Section 17A of the Exchange Act. DTC was
created to hold securities for its participants (collectively, the
"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 CIBC), 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 (collectively, the "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.
 
  The Issuers expect that pursuant to procedures established by DTC (i) upon
deposit of each Global Note, DTC will credit the accounts of Participants
designated by CIBC with an interest in the Global Note and (ii) ownership of
the Notes will be 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).
 
                                      108
<PAGE>
 
  The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form.
Accordingly, the ability to transfer interests in the Notes represented by a
Global Note to such 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 such
interest to persons or entities that do not participate in DTC's system, or to
otherwise take actions in respect of such interest, may be affected by the
lack of a physical definitive security in respect of such 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 such 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
thereunder. Accordingly, each holder owning a beneficial interest in a Global
Note must rely on the procedures of DTC and, if such holder is not a
Participant or an Indirect Participant, on the procedures of the Participant
through which such holder owns its interest, to exercise any rights of a
holder of Notes under the Indenture or such Global Note. The Issuers
understand that under existing industry practice, in the event that the
Issuers 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 such action and the Participants would authorize
holders owning through such Participants to take such action or would
otherwise act upon the instruction of such holders. Neither the Issuers 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 such
Notes.
 
  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 such
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 thereof for the purpose of
receiving payment thereon and for any and all other purposes whatsoever.
Accordingly, neither the Issuers nor the Trustee have or will have any
responsibility or liability for the payment of such 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 Cedel 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 Cedel participants, on the other hand, will be effected
through DTC in accordance with DTC's rules on behalf of Euroclear or Cedel, as
the case may be, by its respective depositary; however, such cross-market
transactions will require delivery of instructions to Euroclear or Cedel, as
the case may be, by the counterparts in such system in accordance with the
rules and procedures and within the established deadlines (Brussels time) of
such system. Euroclear or Cedel, 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
 
                                      109
<PAGE>
 
applicable to DTC. Euroclear participants and Cedel participants may not
deliver instructions directly to the depositaries for Euroclear or Cedel.
 
  Because of time zone differences, the securities account of a Euroclear or
Cedel 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 Cedel participant, during the securities settlement
processing day (which must be a business day for Euroclear and Cedel)
immediately following the settlement date of DTC. Cash received in Euroclear
or Cedel as a result of sales of interest in a Global Security by or through a
Euroclear or Cedel 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 Cedel cash account only as of the business day for Euroclear or
Cedel following DTC's settlement date.
 
  Although DTC, Euroclear and Cedel have agreed to the foregoing procedures to
facilitate transfers of interests in the Global Notes among participants in
DTC, Euroclear and Cedel, they are under no obligation to perform or to
continue to perform such procedures, and such procedures may be discontinued
at any time. Neither the Issuers nor the Trustee will have any responsibility
for the performance by DTC, Euroclear or Cedel or their respective
participants or indirect participants of their respective obligations under
the rules and procedures governing their operations.
 
CERTIFICATED NOTES
 
  If (i) the Issuers 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 such notice or cessation, (ii) the Issuers, at
their option, notify the Trustee in writing that it elects to cause the
issuance of Notes in definitive form under the Indenture or (iii) upon the
occurrence of certain other events as provided in the Indenture, 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
required to register such Certificated Notes in the name of such person or
persons (or the nominee of any thereof) and cause the same to be delivered
thereto.
 
  Neither the Issuers 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).

                              THE EXCHANGE OFFER
 
  The following description of the Registration Rights Agreement is a summary
only, does not purport to be complete and is subject to, and qualified in its
entirety by reference to, all provisions of the Registration Rights Agreement,
a copy of which is filed as an exhibit to the Exchange Offer Registration
Statement of which this Prospectus is a part.
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
  The Original Notes were originally sold by the Issuers on August 21, 1998 to
CIBC pursuant to a Restructuring Agreement. CIBC subsequently resold the
Original Notes within the United States to qualified institutional buyers in
reliance on Rule 144A under the Securities Act and outside the United States
in accordance with Regulation S under the Securities Act. As a condition to
the Restructuring Agreement, the Issuers and Insight Ohio have entered into
the Registration Rights Agreement pursuant to which they have agreed, for the
benefit of the holders of the Original Notes, that they will, at their cost,
(i) by October 20, 1998, file a registration statement (the "Exchange Offer
Registration Statement") with the SEC with respect to a registered offer to
exchange the Original Notes for the Exchange Notes, which will have terms
substantially identical in all material respects to the Original Notes (except
that the Exchange Notes will not contain terms with respect to transfer
restrictions), and (ii) by January 18, 1999, use their reasonable best efforts
to cause the Exchange Offer Registration Statement to be declared effective
under the Securities Act. Upon the Exchange Offer Registration Statement being
declared effective, the Issuers will offer the Exchange Notes in exchange for
surrender of the Original Notes. The Issuers will keep the Exchange Offer open
for not less than 20 business days (or longer if required by applicable law)
after the date notice of the Exchange Offer is mailed to the holders of the
Original Notes. For each Original Note surrendered to the Issuers pursuant to
the Exchange Offer, the holder of such Original Note will receive an Exchange
Note having a principal amount equal to that of the surrendered Original Note.
 
  Under existing SEC interpretations, the Exchange Notes would in general be
freely transferable after the Exchange Offer without further registration
under the Securities Act; provided that in the case of broker-dealers, a
prospectus meeting the requirements of the Securities Act must be delivered as
required. The Issuers have agreed for a period of 180 days after consummation
of the Exchange Offer to make available a prospectus meeting the requirements
of the Securities Act to any broker-dealer for use in connection with any
resale of any such Exchange Notes acquired as described below. A broker-dealer
which delivers such a prospectus to purchasers in connection with such resales
will be subject to certain of the civil liability provisions under the
Securities Act and will be bound by the provisions of the Registration Rights
Agreement (including certain indemnification rights and obligations).
 
  Each holder of the Original Notes that wishes to exchange such Original
Notes for Exchange Notes in the Exchange Offer will be required to make
certain representations including representations that:
  .  any Exchange Notes to be received by it will be acquired in the ordinary
     course of its business;
  .  it has no arrangement or understanding with any person to participate in
     the distribution of the Exchange Notes;
  .  it is not an "affiliate," as defined in Rule 405 of the Securities Act,
     of the Issuers, or if it is an affiliate, it will comply with the
     registration and prospectus delivery requirements of the Securities Act
     to the extent applicable; and
  .  it is not acting on behalf of any person who could not truthfully make
     the foregoing representations.
 
  If the holder is not a broker-dealer, it will be required to represent that
it is not engaged in, and does not intend to engage in, the distribution of
the Exchange Notes. If the holder is a broker-dealer that will receive
Exchange Notes for its own account in exchange for Original Notes that were
acquired as a result of marketmaking activities or other trading activities,
it will be required to acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes.
 
                                      111
<PAGE>
 
  In the event that applicable interpretations of the staff of the SEC do not
permit the Issuers to effect the Exchange Offer, or if for any other reason
the Exchange Offer is not consummated within 180 days of the Issue Date, the
Issuers will, at their own expense, (a) as promptly as practicable, file a
shelf registration statement covering resales of the Original Notes (the
"Shelf Registration Statement"), (b) use their reasonable best efforts to
cause the Shelf Registration Statement to be declared effective under the
Securities Act, and (c) use their reasonable best efforts to keep effective
the Shelf Registration Statement until two years after its effective date. The
Issuers will, in the event of the Shelf Registration Statement, provide to
each holder of the Original Notes copies of the prospectus which is a part of
the Shelf Registration Statement, notify each such holder when the Shelf
Registration Statement for the Original Notes has become effective and take
certain other actions as are required to permit unrestricted resales of the
Original Notes. A holder of the Original Notes that sells such Original Notes
pursuant to the Shelf Registration Statement generally will be required to be
named as a selling securityholder in the related prospectus and to deliver a
prospectus to purchasers, will be subject to certain of the civil liability
provisions under the Securities Act in connection with such sales and will be
bound by the provisions of the Registration Rights Agreement which are
applicable to such a holder (including certain indemnification rights and
obligations).
 
  If (i) the Exchange Offer Registration Statement is not filed by October 20,
1998, (ii) an Exchange Offer Registration Statement is not declared effective
by January 18, 1999 (iii) the Shelf Registration is not filed or is not
declared effective within the periods specified in the Registration Rights
Agreement, or (iv) either (A) the Issuers have not exchanged the Exchange
Notes for all Original Notes validly tendered in accordance with the terms of
the Exchange Offer on or prior to February 17, 1999 or (B) the Exchange Offer
Registration Statement ceases to be effective at any time prior to the time
that the Exchange Offer is consummated as to all Original Notes validly
tendered or (C) if applicable, the Shelf Registration Statement has been
declared effective and such Shelf Registration Statement ceases to be
effective at any time prior to the second anniversary of its effective date
(each of such events referred to in clauses (i) through (iii) above is a
"Registration Default"), the sole remedy available to holders of the Original
Notes will be the immediate assessment of additional interest (the "Additional
Interest") as follows: the per annum interest rate on the Original Notes will
increase by 50 basis points for the first 90 days during which any such
default exists, and the per annum interest rate will increase by an additional
25 basis points for each subsequent 90-day period during which the
Registration Default remains uncured, up to a maximum additional interest rate
of 200 basis points per annum in excess of the interest rate on the cover of
this Prospectus. All Additional Interest will be payable to holders of the
Original Notes in cash on each interest payment date, commencing with the
first such date occurring after any such Additional Interest commences to
accrue, until such Registration Default is cured. After the date on which such
Registration Default is cured, the interest rate on the Original Notes will
revert to the interest rate originally borne by the Original Notes (as shown
on the cover of this Prospectus).
 
  If the Exchange Offer is made and CIBC continues to hold Original Notes,
CIBC may exchange Original Notes for other notes identical to the Exchange
Notes except for transfer restrictions ("Private Exchange Notes"). If they
receive Private Exchange Notes, CIBC thereafter will have the right for a
period after consummation of the Exchange Offer to request the Issuers to file
a shelf registration statement covering the Private Exchange Notes. If such
requested shelf registration is not filed or does not become effective by the
times provided in the Registration Rights Agreement, the Issuers shall pay as
liquidated damages to holders of the Private Exchange Notes the Additional
Interest as provided above until such time as it does become effective.
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Issuers will accept any and all Original
Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. The Issuers will issue $1,000 principal amount
of Exchange Notes in exchange for each $1,000 principal amount of outstanding

                                      112
<PAGE>
 
  The form and terms of the Exchange Notes are the same as the form and terms
of the Original Notes except that (i) the Exchange Notes bear a different
CUSIP Number from the Original Notes, (ii) the Exchange Notes have been
registered under the Securities Act and hence will not bear legends
restricting the transfer thereof and (iii) the holders of the Exchange Notes
will not be entitled to certain rights under the Registration Rights
Agreement, which rights will terminate when the Exchange Offer is terminated.
The Exchange Notes will evidence the same debt as the Original Notes and will
be entitled to the benefits of the Indenture.
 
  As of the date of this Prospectus, $140,000,000 aggregate principal amount
of Original Notes were outstanding. The Issuers have fixed the close of
business on      ,    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 Original Notes do not have any appraisal or dissenters' rights
under the Ohio Corporation Law, the Florida Partnership Laws, the Delaware
Limited Liability Company Law or the Indenture in connection with the Exchange
Offer. The Issuers intend to conduct the Exchange Offer in accordance with the
applicable requirements of the Exchange Act and the rules and regulations of
the SEC thereunder.
 
  The Issuers shall be deemed to have accepted validly tendered Original Notes
when, as and if the Issuers 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 the Issuers.
 
  If any tendered Original Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth in this
Prospectus or otherwise, the certificates for any such unaccepted Original
Notes will be returned, without expense, to the tendering holder thereof as
promptly as practicable after the Expiration Date.
 
  Holders who tender Original 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 Original
Notes pursuant to the Exchange Offer. The Issuers will pay all charges and
expenses, other than transfer taxes in certain circumstances, in connection
with the Exchange Offer. See "--Fees and Expenses" below.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
       ,     , unless the Issuers, in their sole discretion, extend the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended. Notwithstanding the
foregoing, the Issuers will not extend the Expiration Date beyond           ,
    .
 
  In order to extend the Exchange Offer, the Issuers 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.
 
  The Issuers reserve the right, in their sole discretion, (i) to delay
accepting any Original Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "--Conditions"
shall not have been satisfied, by giving oral or written notice of such delay,
extension or termination to the Exchange Agent or (ii) to amend the terms of
the Exchange Offer in any manner. Any such 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 Original Notes that are accepted for exchange will receive, in cash,
accrued interest thereon to, but not including, the date
 
                                      113
<PAGE>
 
of issuance of the Exchange Notes. Such interest will be paid with the first
interest payment on the Exchange Notes on February 15, 1999. Interest on the
Original 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 15
and August 15.
 
PROCEDURES FOR TENDERING
 
  Only a holder of Original Notes may tender such Original 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, and
mail or otherwise deliver such Letter of Transmittal, or such facsimile,
together with the Original 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 Original Notes, Letter of Transmittal 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 Original Notes may be
made by book-entry transfer in accordance with the procedures described below.
Confirmation of such book-entry transfer must be received by the Exchange
Agent prior to the Expiration Date.
 
  By executing the Letter of Transmittal, each holder will make to the Issuers
the representations set forth above under the heading "--Purpose and Effect of
the Exchange Offer."
 
  The tender by a holder and the acceptance thereof by the Issuers will
constitute the agreement between such holder and the Issuers in accordance
with the terms and subject to the conditions set forth in this Prospectus and
in the Letter of Transmittal.
 
  THE METHOD OF DELIVERY OF ORIGINAL NOTES AND THE LETTER OF TRANSMITTAL 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 ORIGINAL NOTES SHOULD BE SENT TO
THE ISSUERS. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH
HOLDERS.
 
  Any beneficial owner whose Original Notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact such registered holder promptly and instruct such
registered holder to tender on such 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 firm of the Medallion System (an
"Eligible Institution") unless the Original Notes tendered pursuant thereto
are tendered (i) by a registered holder who has not completed the box entitled
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter
of Transmittal or a notice of withdrawal, as the case may be, are required to
be guaranteed, such guarantee must be by an Eligible Institution.
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Original Notes listed therein, such Original Notes must be
endorsed or accompanied by a properly completed bond power, signed by such
registered holder as such registered holder's name appears on such Original
Notes with the signature thereon guaranteed by an Eligible Institution.
 
                                      114
<PAGE>
 
  If the Letter of Transmittal or any Original 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 evidence satisfactory to the
Issuers of their authority to so act must be submitted with the Letter of
Transmittal.
 
  The Issuers understand that the Exchange Agent will make a request promptly
after the date of this Prospectus to establish accounts with respect to the
Original Notes at the book-entry transfer facility, The Depository Trust
Company (the "Book-Entry Transfer Facility"), for the purpose of facilitating
the Exchange Offer, and subject to the establishment thereof, any financial
institution that is a participant in the Book-Entry Transfer Facility's system
may make book-entry delivery of Original Notes by causing such Book-Entry
Transfer Facility to transfer such Original Notes into the Exchange Agent's
account with respect to the Original Notes in accordance with the Book-Entry
Transfer Facility's procedures for such transfer. Although delivery of the
Original Notes may be effected through book-entry transfer into the Exchange
Agent's account at the Book-Entry Transfer Facility, an appropriate Letter of
Transmittal properly completed and duly executed with any required signature
guarantee and all other required documents must in each case be transmitted to
and received or confirmed by the Exchange Agent at its address set forth below
on or prior to the Expiration Date, or, if the guaranteed delivery procedures
described below are complied with, within the time period provided under such
procedures. Delivery of documents to the Book-Entry Transfer Facility does not
constitute delivery to the Exchange Agent.
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of tendered Original Notes and withdrawal of tendered
Original Notes will be determined by the Issuers in their sole discretion,
which determination will be final and binding. The Issuers reserve the
absolute right to reject any and all Original Notes not properly tendered or
any Original Notes the Issuers' acceptance of which would, in the opinion of
counsel for the Issuers, be unlawful. The Issuers also reserve the right in
their sole discretion to waive any defects, irregularities or conditions of
tender as to particular Original Notes. The Issuers' interpretation of the
terms and conditions of the Exchange Offer (including the instructions in the
Letter of Transmittal) will be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Original
Notes must be cured within such time as the Issuers shall determine. Although
the Issuers intend to notify holders of defects or irregularities with respect
to tenders of Original Notes, neither the Issuers, the Exchange Agent nor any
other person shall incur any liability for failure to give such notification.
Tenders of Original Notes will not be deemed to have been made until such
defects or irregularities have been cured or waived. Any Original 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 Original Notes and (i) whose Original Notes
are not immediately available, (ii) who cannot deliver their Original Notes,
the Letter of Transmittal or any other required documents to the Exchange
Agent or (iii) who cannot complete the procedures for book-entry transfer,
prior to the Expiration Date, may effect a tender if;
 
    (a) the tender is made through an Eligible Institution;
 
    (b) prior to the Expiration Date, the Exchange Agent receives from such
  Eligible Institution 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 such Original Notes and the principal amount of Original Notes tendered,
  stating that the tender is being made thereby and guaranteeing that, within
  five New York Stock Exchange trading days after the Expiration Date, the
  Letter of Transmittal (or facsimile thereof) together with the
  certificate(s) representing the Original Notes (or a confirmation of book-
  entry transfer of such Original Notes into the Exchange Agent's account at
  the Book-Entry Transfer Facility), and any other documents required by the
  Letter of Transmittal will be deposited by the Eligible Institution with
  the Exchange Agent; and
 
                                      115
<PAGE>
 
    (c) such properly completed and executed Letter of Transmittal (of
  facsimile thereof), as well as the certificate(s) representing all tendered
  Original Notes in proper form for transfer (or a confirmation of book-entry
  transfer of such Original Notes into the Exchange Agent's account at the
  Book-Entry Transfer Facility), and all other documents required by the
  Letter of Transmittal are received by the Exchange Agent upon five New York
  Stock Exchange trading days after the Expiration Date.
 
  Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Original Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided in this Prospectus, tenders of Original Notes
may be withdrawn at any time prior to 5:00 p.m., New York City time, on the
Expiration Date.
 
  To withdraw a tender of Original 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. Any such notice of
withdrawal must (i) specify the name of the person having deposited the
Original Notes to be withdrawn (the "Depositor"), (ii) identify the Original
Notes to be withdrawn (including the certificate number(s) and principal
amount of such Original Notes, or, in the case of Original Notes transferred
by book-entry transfer, the name and number of the account at the Book-Entry
Transfer Facility to be credited), (iii) be signed by the holder in the same
manner as the original signature on the Letter of Transmittal by which such
Original Notes were tendered (including any required signature guarantees) or
be accompanied by documents of transfer sufficient to have the Trustee with
respect to the Original Notes register the transfer of such Original Notes
into the name of the person withdrawing the tender and (iv) specify the name
in which any such Original Notes are to be registered, if different from that
of the Depositor. All questions as to the validity, form and eligibility
(including time of receipt) of such notices will be determined by the Issuers,
whose determination shall be final and binding on all parties. Any Original
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 Original Notes so withdrawn are validly retendered.
Any Original Notes which have been tendered but which are not accepted for
exchange will be returned to the holder thereof without cost to such holder as
soon as practicable after withdrawal, rejection of tender or termination of
the Exchange Offer. Properly withdrawn Original 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, the Issuers shall not
be required to accept for exchange, or exchange Exchange Notes for, any
Original Notes, and may terminate or amend the Exchange Offer as provided in
this Prospectus before the acceptance of such Original Notes, if:
 
    (a) 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 the reasonable judgment of the Issuers, might materially impair
  the ability of the Issuers to proceed with the Exchange Offer or any
  material adverse development has occurred in any existing action or
  proceeding with respect to the Issuers or any of their Subsidiaries; or
 
    (b) any law, rule, regulation or interpretation by the staff of the SEC
  is proposed, adopted or enacted, which, in the reasonable judgment of the
  Issuers, might materially impair the ability of the Issuers to proceed with
  the Exchange Offer or materially impair the contemplated benefits of the
  Exchange Offer to the Issuers; or
 
    (c) any governmental approval has not been obtained, which approval the
  Issuers shall, in their reasonable discretion, deem necessary for the
  consummation of the Exchange Offer and contemplated hereby.
 
                                      116
<PAGE>
 
  If the Issuers determine in their reasonable judgment that any of the
conditions are not satisfied, the Issuers may (i) refuse to accept any
Original Notes and return all tendered Original Notes to the tendering
holders, (ii) extend the Exchange Offer and retain all Original Notes tendered
prior to the expiration of the Exchange Offer, subject, however, to the rights
of holders to withdraw such Original Notes (see "--Withdrawal of Tenders") or
(iii) waive such unsatisfied conditions with respect to the Exchange Offer and
accept all properly tendered Original Notes which have not been withdrawn.
 
EXCHANGE AGENT
 
  Bank of Montreal Trust Company has been appointed as Exchange Agent for the
Exchange Offer. Questions and requests for assistance, requests for additional
copies of this Prospectus or of the Letter of Transmittal and requests for
Notice of Guaranteed Delivery should be directed to the Exchange Agent
addressed as follows:
 
  Bank of Montreal Trust Company
  88 Pine Street, 19th Floor
  New York, New York 10005
  Attn: Corporate Trust Department
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders will be borne by the Issuers. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telecopy, telephone or in person by officers and
regular employees of the Issuers and their affiliates.
 
  The Issuers 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. The Issuers, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of-pocket expenses in connection
therewith.
 
  The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Issuers. 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
Original Notes, which is face value, as reflected in the Issuers' accounting
records on the date of exchange. Accordingly, no gain or loss for accounting
purposes will be recognized by the Issuers. The expenses related to the
issuance of the Notes and of the Exchange Offer will be amortized over the
term of the Exchange Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  The Original Notes that are not exchanged for Exchange Notes pursuant to the
Exchange Offer will remain restricted securities. Accordingly, such Original
Notes may be resold only (i) to the Issuers (upon redemption thereof or
otherwise), (ii) so long as the Original Notes are eligible for resale
pursuant to Rule 144A under the Securities Act, to a person inside the United
States whom the seller reasonably believes is a qualified institutional buyer
within the meaning of Rule 144A in a transaction meeting the requirements of
Rule 144A, in accordance with Rule 144 under the Securities Act, or pursuant
to another exemption from the registration requirements of the Securities Act
(and based upon an opinion of counsel reasonably acceptable to the Issuers),
(iii) outside the United States to a foreign person in a transaction meeting
the requirements of Rule 904 under the Securities Act, (iv) to certain
institutional "accredited investors" within the meaning of Rule 501(a) under
the Securities Act, in a minimum principal amount of $250,000, or (v) pursuant
to an effective registration statement under the Securities Act, in each case
in accordance with any applicable securities laws of any state of the United
States.

RESALE OF EXCHANGE NOTES
 
  With respect to resales of Exchange Notes, based on no-action letters issued
by the staff of the SEC to third parties, the Issuers believe that a holder or
other person who receives Exchange Notes, whether or not such person is the
holder (other than a person that is an "affiliate" of the Issuers within the
meaning of Rule 405 under the Securities Act), who receives Exchange Notes in
exchange for Original 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, such holder cannot
rely on the position of the staff of the SEC enunciated in such no-action
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
Participating Broker-Dealer that receives Exchange Notes for its own account
in exchange for Original Notes, where such Original Notes were acquired by
such Participating Broker-Dealer as a result of market-making activities or
other trading activities, must acknowledge that it will deliver a prospectus
in connection with any resale of such Exchange Notes. See "Plan of
Distribution."
 
  As contemplated by these no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent
to the Issuers in the Letter of Transmittal that (i) the Exchange Notes are to
be acquired by the holder or the person receiving such Exchange Notes, whether
or not such person is the holder, in the ordinary course of business, (ii) the
holder or any such other person (other than a broker-dealer referred to in the
next sentence) is not engaging and does not intend to engage, in the
distribution of the Exchange Notes, (iii) the holder or any such other person
has no arrangement or understanding with any person to participate in the
distribution of the Exchange Notes, (iv) neither the holder nor any such other
person is an "affiliate" of the Issuers within the meaning of Rule 405 under
the Securities Act, and (v) the holder or any such other person acknowledges
that if such holder or other person participates in the Exchange Offer for the
purpose of distributing the Exchange Notes it must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale of the Exchange Notes and cannot rely on those no-
action letters. As indicated above, each Participating Broker-Dealer that
receives an Exchange Note for its own account in exchange for Original Notes
that were acquired as a result of market-making or other trading activities
must acknowledge that it will deliver a prospectus in connection with any
resale of such Exchange Notes. For a description of the procedures for such
resales by Participating Broker-Dealers, see "Plan of Distribution."

                CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a summary of certain federal tax consequences under the
Internal Revenue Code of 1986, as amended (the "Code"). This summary is based
upon the laws, regulations, rulings and judicial decisions in effect on the
date of this offering circular, all of which are subject to change at any time
(possibly on a retroactive basis). There can be no assurance that the Internal
Revenue Service (the "IRS") will not take a contrary view, and no ruling from
the IRS has been or will be sought. Unless otherwise specifically noted, this
summary applies only to those persons who acquire Notes for cash and who hold
Notes as capital assets, and it does not discuss all aspects of federal income
taxation that may be relevant to Holders in light of their particular
investment circumstances. This Summary does not address the consequences to
certain types of Holders subject to special treatment under the federal income
tax laws (for example, tax-exempt organizations, dealers in securities,
financial institutions, life insurance companies and persons holding Notes as
part of a hedging or "conversion" transaction or a straddle). This summary
also does not discuss the federal alternative minimum tax consequences to a
Holder under state, local or foreign tax laws, which may differ from the
corresponding federal income tax laws. Holders of Original Notes and
prospective investors in Exchange Notes are advised to consult their own tax
advisors regarding the particular tax considerations pertaining to them with
respect to the exchanging of Original Notes for Exchange Notes, and the
ownership and disposition of Exchange Notes, in each case including the
effects of applicable federal, state, local, foreign or other tax laws to
which they may be subject, as well as possible changes in the tax laws.
 
  For purposes of this discussion, a U.S. Holder is a Holder that is: a
citizen or resident (as determined for United States federal income tax
purposes) of the United States; a corporation or partnership (or other entity
treated for U.S. income tax purposes as a corporation or partnership) created
or organized in the United States or under the laws of the United States or of
any political subdivision thereof; an estate the income of which is includible
in gross income for U.S. federal income tax purposes, regardless of its
source; or a trust if a court within the United States is able to exercise
primary supervision over the administration of the trust and one or more
United States fiduciaries have the authority to control all substantial
decisions of the trust. A Foreign Holder is any Holder that is not a U.S.
Holder.
 
EXCHANGE OF ORIGINAL NOTES FOR EXCHANGE NOTES
 
  Cooperman Levitt Winikoff Lester & Newman, P.C., counsel to the Issuers, has
advised the Issuers that in its opinion, the exchange of the Original Notes
for Exchange Notes pursuant to the Exchange Offer will not be treated as an
"exchange" for federal income tax purposes because the Exchange Notes will not
be considered to differ materially in kind or extent from the Original Notes.
Rather, in the opinion of counsel to the Issuers, the Exchange Notes received
by a Holder will be treated as a continuation of the Original Notes in the
hands of such Holder and consequently, in the opinion of counsel to the
Issuers, there will be no federal income tax consequences to Holders
exchanging Original Notes for Exchange Notes pursuant to the Exchange Offer.
 
  The Issuers recommend that each Holder of Original Notes consult such
Holder's own tax adviser as to the particular tax consequences of exchanging
such Holder's Original Notes for Exchange Notes, including the applicability
and effect of any state, local or foreign tax laws.
 
INVESTMENTS IN EXCHANGE NOTES BY U.S. HOLDERS
 
 Payments of Interest
 
  A U.S. Holder generally will be required to report as ordinary income for
federal income tax purposes interest received or accrued on an Exchange Note
in accordance with the U.S. Holder's method of tax accounting.
 
 Market Discount
 
  If a U.S. Holder purchases an Exchange Note for an amount that is less than
its "stated redemption price at maturity" (which, in the case of the Exchange
Notes, is their principal amount), the amount of the difference
 
                                      119
<PAGE>
 
will be treated as "market discount" for federal income tax purposes, unless
such difference is less than a specified de minimis amount. Under the market
discount rules, a U.S. Holder is required to treat any principal payment on,
or any gain on the sale, exchange, retirement or other disposition of, an
Exchange Note as ordinary income to the extent of the accrued market discount
which has not previously been included in income at the time of such payment
or disposition. In addition, such a U.S. Holder may be required to defer until
maturity of the Exchange Note or its earlier disposition in a taxable
transaction the deduction of all or a portion of the interest expense of any
indebtedness incurred or continued to purchase or carry such Exchange Note.
 
  Any market discount will be considered to accrue ratably during the period
from the date of acquisition to the maturity date of the Exchange Note, unless
the U.S. Holder elects to accrue the market discount on a constant interest
method. A U.S. Holder of an Exchange Note may elect to include market discount
in income currently as it accrues (on either a ratable or constant interest
method), in which case the rule described above regarding deferral of interest
deductions will not apply. This election to include market discount in income
currently, once made, applies to all market discount obligations acquired
during or after the first taxable year to which the election applies and may
not be revoked without the consent of the IRS.
 
 Bond Premium
 
  A U.S. Holder who purchases an Exchange Note for an amount in excess of its
stated redemption price at maturity will be considered to have purchased the
Exchange Note with "amortizable bond premium" equal to the amount of such
excess. A U.S. Holder generally may elect to amortize the premium on the
constant yield to maturity method. The amount amortized in any year will be
treated as a reduction of the U.S. Holder's interest income from the Exchange
Note during such year and will reduce the U.S. Holder's adjusted tax basis in
the Exchange Note by such amount. A U.S. Holder of an Exchange Note that does
not make the election to amortize the premium will not reduce its tax basis in
the Exchange Note and thus effectively will realize a smaller gain, or a
larger loss, on a taxable disposition of the Exchange Note than it would have
realized had the election been made. The election to amortize the premium on a
constant yield to maturity method, once made, applies to all debt obligations
held or subsequently acquired by the electing U.S. Holder on or after the
first day of the first taxable year to which the election applies and may not
be revoked without the consent of the IRS.
 
 Sale, Exchange or Retirement of Exchange Notes
 
  A U.S. Holder's tax basis in an Exchange Note generally will equal the
purchase price paid therefor, increased by market discount previously included
in income by such U.S. Holder and reduced by any amortized premium and any
principal payments on the Exchange Note. Upon the sale, exchange or retirement
(including redemption) of an Exchange Note, a U.S. Holder of an Exchange Note
generally will recognize gain or loss equal to the difference between the
amount realized upon the sale, exchange or retirement of the Exchange Note
(other than in respect of accrued and unpaid interest on the Exchange Note,
which will be taxable as ordinary income) and the adjusted tax basis in the
Exchange Note. Such gain or loss generally will be capital gain or loss,
except to the extent of any accrued market discount, which will be taxable as
ordinary income.
 
  Under current law, net capital gains of individuals generally are subject to
the following maximum federal tax rates: (i) twenty percent, for property held
more than one year; and (ii) beginning in the year 2006, eighteen percent, for
property acquired after the year 2000 and held for more than five years. The
deductibility of capital losses is subject to limitations.
 
INVESTMENTS IN EXCHANGE NOTES BY FOREIGN HOLDERS
 
  If the income or gain on the Exchange Notes is "effectively connected with
the conduct of a trade or business within the United States" ("ECI") of a
Foreign Holder, such income or gain will be subject to tax essentially in the
same manner as if the Exchange Notes were held by a U.S. Holder, as discussed
above, and in the case of a Foreign Holder that is a foreign corporation, may
also be subject to the federal branch profits tax.

  If the income on the Exchange Notes is not ECI, then under the "portfolio
interest" exception to the general rules for the withholding of tax on
interest paid to a Foreign Holder, a Foreign Holder will not be subject to
United States tax (or to withholding) on interest on an Exchange Note,
provided that (i) the Foreign Holder does not actually or constructively own
10% or more of the outstanding voting stock of Coaxial and is not a partner
owning a 10% or greater capital or profits interest in Phoenix, in each case
within the meaning of Section 871(h)(3) of the Code, (ii) the Foreign Holder
is not a controlled foreign corporation that is considered related to the
Issuers and (iii) the Issuers, their paying agent or the person who would
otherwise be required to withhold tax received either (a) a statement (an
"Owner's Statement") on IRS Form W-8 (which must be renewed periodically),
signed under penalties of perjury by the beneficial owner of the Exchange
Note, on which the owner certifies that the owner is not a United States
person and which provides the owner's name and address, or (B) a statement
signed under penalties of perjury by a financial institution holding the
Exchange Note on behalf of the beneficial owners, together with a copy of each
beneficial owner's Owner's Statement. A Foreign Holder who does not qualify
for the "portfolio interest" exception would be subject to United States
withholding tax at a flat rate of 30% (or a lower applicable treaty rate upon
delivery of requisite certification of eligibility) on interest payments on
the Exchange Notes.
 
  If the gain on the Exchange Notes is not ECI, then gain recognized by a
Foreign Holder upon the redemption, sale or exchange of an Exchange Note
(including any gain representing accrued market discount) will not be subject
to United States tax unless the Foreign Holder is an individual present in the
United States for 183 days or more during the taxable year in which the
Exchange Note is redeemed, sold or exchanged, and certain other requirements
are met, in which case the Foreign Holder will be subject to United States tax
at a flat rate of 30% (unless exempt by applicable treaty upon delivery of
requisite certification of eligibility). Foreign Holders who are individuals
may also be subject to tax pursuant to provisions of United States federal
income tax law applicable to certain United States expatriates.
 
   An Exchange Note that is held by an individual who at the time of death is
not a citizen or resident of the United States will not be subject to U.S.
federal estate tax as a result of such individual's death, provided that, at
the time of the individual's death, payments of interest with respect to such
Exchange Note would have qualified for the portfolio interest exception.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
  Certain (generally, non-corporate) U.S. Holders may be subject to backup
withholding at a rate of 31% on payments of principal, premium and interest
on, and the proceeds of the disposition of, the Exchange Notes. In general,
backup withholding will be imposed only if the U.S. Holder (i) fails to
furnish its taxpayer identification number ("TIN"), which, for an individual,
would be his or her Social Security number, (ii) furnishes an incorrect TIN,
(iii) is notified by the IRS that it has failed to report payments of interest
or dividends or (iv) under certain circumstances, fails to certify, under
penalty of perjury, that it has furnished a correct TIN and that it is not
subject to backup withholding. In addition, such payments of principal and
interest to U.S. Holders will generally be subject to information reporting.
 
  Backup withholding and information reporting generally will not apply to
interest payments made to a Foreign Holder of an Exchange Note who provides
the requisite certification or otherwise establishes an exemption from backup
withholding. Payments of the proceeds of a disposition of the Exchange Notes
by or through a United States office of a broker generally will be subject to
backup withholding at a rate of 31% and information reporting unless the
Foreign Holder certifies that it is a Foreign Holder under penalty of perjury
or otherwise establishes an exemption. Payments of the proceeds of a
disposition of the Exchange Notes by or through a foreign office of a United
States broker or foreign broker with certain relationships to the United
States generally will be subject to information reporting, but not backup
withholding.
 
  The amount of any backup withholding imposed on a payment to a Holder of an
Exchange Note will be allowed as a credit against such Holder's United States
federal income tax liability, and such Holder may be entitled to a refund,
provided that the required information is furnished to the IRS.
 
                                      121
<PAGE>
 
  Holders should consult their tax advisors as to their qualification for
exemption from backup withholding and the procedure for obtaining such an
exemption.
 
RECENTLY ISSUED TREASURY REGULATIONS
 
  The U.S. Treasury Department recently issued final Treasury regulations
governing information reporting and the certification procedures regarding
withholding and backup withholding on certain amounts paid to Foreign Holders
after December 31, 1999. The new Treasury regulations generally would not
alter the treatment of Foreign Holders described above. The new Treasury
regulations would alter the procedures for claiming the benefits of an income
tax treaty and may change the certification procedures relating to the receipt
by intermediaries of payments on behalf of a beneficial owner of an Exchange
Note. Prospective investors should consult their tax advisors concerning the
effect, if any, of such new Treasury regulations on an investment in the
Exchange Notes.
 
THE FOREGOING SUMMARY IS INCLUDED FOR GENERAL INFORMATION ONLY. HOLDERS OF
ORIGINAL NOTES AND PROSPECTIVE PURCHASERS OF EXCHANGE NOTES SHOULD CONSULT
THEIR OWN TAX ADVISORS AS TO SPECIFIC CONSEQUENCES OF THE EXCHANGING OF
ORIGINAL NOTES FOR EXCHANGE NOTES, AND OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF EXCHANGE NOTES, IN EACH CASE INCLUDING THE APPLICATION AND
EFFECT OF FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS.

                             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 such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be
used in connection with resales of Exchange Notes received in exchange for
Original Notes only by Participating Broker-Dealers ("Eligible Participating
Broker-Dealers") who acquired such Original Notes as a result of market-making
activities or other trading activities and not by Participating Broker-Dealers
who acquired such Original Notes directly from the Issuers. The Issuers have
agreed that for a period of 90 days after the Expiration Date, they will make
this Prospectus, as amended or supplemented, available to any Eligible
Participating Broker-Dealer for use in connection with any such resale. In
addition, until       , all dealers effecting transactions in the Exchange
Notes may be required to deliver a prospectus.
 
  The Issuers 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 such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such Participating Broker-
Dealer and/or the purchasers of any such 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 such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commission 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 90 days after the Expiration Date, the Issuers will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any Eligible Participating Broker-Dealer that requests such
documents in the Letter of Transmittal. The Issuers have agreed to pay all
expenses incident to the Exchange Offer (including the expenses of one counsel
for the Holders of the Notes) other than commissions or concessions of any
Participating Broker-Dealer and will indemnify the Holders of the Notes
(including any Participating Broker-Dealers) against certain liabilities
including liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
  Certain legal matters with respect to the Exchange Notes offered hereby will
be passed upon for the Issuers by Cooperman Levitt Winikoff Lester & Newman,
P.C., New York, New York.

                       ADDITIONAL AVAILABLE INFORMATION
 
  The Issuers have filed with the SEC a Registration Statement on Form S-4
(together with all amendments, exhibits and schedules thereto, the
"Registration Statement") under the Securities Act with respect to the
Exchange Notes offered hereby. This Prospectus does not contain all the
information set forth in the Registration Statement, certain parts of which
are omitted in accordance with the rules and regulations of the SEC, and to
which reference is hereby made. Statements contained in this Prospectus as to
the contents of any contract, agreement or any other document referred to are
not necessarily complete. With respect to each such contract, agreement or
other document filed as an exhibit to the Registration Statement, reference is
made to such exhibit to the Registration Statement for a more complete
description of the matter involved, and each such statement shall be deemed
qualified in its entirety by such reference.
 
  The Registration Statement can be inspected and copied at the Public
Reference Section of the SEC at Room 1024, 450 Fifth Street, N.W., Washington,
D.C. 20459, and at the SEC's regional offices at Seven World Trade Center, New
York, New York 10048, and Citicorp Center, 600 West Madison Street, Suite
1400, Chicago, Illinois 60661-2511. Copies of the Registration Statement can
be obtained from the Public Reference Section of the SEC at Room 1024, 450
Fifth Street, N.W., Washington, D.C. 20459, at prescribed rates. The Issuers
are filing the Registration Statement with the SEC electronically. The SEC
maintains a web site that contains reports, proxy and information statements
and other information regarding registrants that file electronically with the
SEC. The address of that web site is http://www.sec.gov.
 
  As a result of the Exchange Offer, the Issuers will be subject to the
information reporting requirements of the Exchange Act. So long as the Issuers
are subject to such periodic reporting requirements under the Exchange Act,
they will continue to furnish the information required thereby to the SEC. The
Issuers will be required to file periodic reports with the SEC pursuant to the
Exchange Act during the Issuers' current fiscal year and thereafter so long as
the Notes are held by at least 300 registered holders. The Issuers do not
anticipate that, for periods following December 31, 1998, the Notes will be
held of record by more than 300 holders. Accordingly, after such date, the
Issuers do not expect to be required to comply with the periodic reporting
obligations imposed under the Exchange Act. However, the Indenture provides
that the Issuers will furnish copies of the periodic reports required to be
filed with the SEC under the Exchange Act to the holders of the Notes. If the
Issuers are not subject to the periodic reporting and informational
requirements of the Exchange Act, they will, to the extent such filings are
accepted by the SEC, and whether or not the Issuers have a class of securities
registered under the Exchange Act, file with the SEC, and provide the Trustee
and the holders of the Notes within 15 days after such filings with, annual
reports containing the information required to be contained in Form 10-K
promulgated under the Exchange Act, quarterly reports containing the
information required to be contained in Form 10-Q promulgated under the
Exchange Act, and from time to time such other information as is required to
be contained in Form 8-K promulgated under the Exchange Act. If filing such
reports with the SEC is not accepted by the SEC or prohibited by the Exchange
Act, the Issuers will also provide copies of such reports, at their cost, to
prospective purchasers of the Notes promptly upon written request.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders of
 Coaxial Communications of Central Ohio, Inc.:
 
  We have audited the accompanying statements of net assets to be contributed
of Central Ohio Cable System Operating Unit as of December 31, 1997 and 1996,
and the related statements of operations and cash flows relating to the net
assets to be contributed for each of the three years in the period ended
December 31, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  The accompanying financial statements of net assets to be contributed were
prepared to present the net assets of Central Ohio Cable System Operating Unit
to be contributed to a newly formed company pursuant to the Contribution
Agreement described in Note 10, and is not intended to be a complete
presentation of Central Ohio Cable System Operating Unit.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets to be contributed of Central Ohio
Cable System Operating Unit as described in Note 10, as of December 31, 1997
and 1996, and the results of its operations and cash flows for each of the
three years in the period ended December 31, 1997 in conformity with generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                          DECEMBER 31, 1997 AND 1996
 
(1) BUSINESS ORGANIZATION AND PURPOSE
 
  Central Ohio Cable System Operating Unit (the Operating Unit), an operating
unit within Coaxial Communications of Central Ohio, Inc. (Central Ohio),
operates a cable television system which provides basic and expanded cable
services to homes in Columbus, Ohio and surrounding areas. The Operating
Unit's financial statements include only those assets, liabilities, revenues
and expenses directly related to the cable television system to be contributed
(see Note 10).
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CASH
 
  The Operating Unit considers all highly liquid investments purchased with
original maturities of three months or less to be cash equivalents.
 
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 VALUES
 
  In December 1991, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 107, "Disclosures about Fair Value of
Financial Instruments," which requires disclosure of fair value information
about both on- and off-balance sheet financial instruments for which it is
practicable to estimate that value. The carrying amounts of current assets and
liabilities approximate their fair market value because of the immediate or
short-term maturity of these financial instruments.
 
OPERATING REVENUE RECOGNITION
 
  Service fees are recorded in the month cable television and pay television
services are provided to subscribers. Connection fees are charges for the
hook-up of new customers and are recognized when billed on the subscriber's
first bill. Unearned revenues are recorded as advance subscriber deposits in
the accompanying financial statements.
 
CONCENTRATION OF CREDIT RISK
 
  Financial instruments that potentially subject the Operating Unit to
concentrations of credit risk consist principally of trade accounts
receivable. The Operating Unit's customer base consists of a number of homes
concentrated in the central Ohio area. The Operating Unit continually monitors
the exposure for credit losses and maintains allowances for anticipated
losses. As of December 31, 1997, the Operating Unit had no significant
concentrations of credit risk.
 
MATERIAL, SUPPLIES AND CONSTRUCTION INVENTORIES
 
  Material, supplies and construction inventories are stated at the lower of
cost (first-in, first-out basis) or market.
 
PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost, while maintenance and repairs are
expensed as incurred. Upon retirement or disposal of assets, the cost and
related accumulated depreciation and amortization are removed from
 
                                      F-7

the balance sheet, and any gain or loss is reflected in earnings. Depreciation
and amortization are provided using the straight-line method over the
estimated useful lives of the related assets as follows:

     <S>                                                          <C>

     Leasehold improvements...................................... Life of lease
</TABLE>
 
  The Operating Unit internally constructs certain CATV systems. Construction
costs capitalized include payroll, fringe benefits and other overhead costs
associated with construction activity.
 
  The Operating Unit reviews its property, plant and equipment and other long
term assets when events or changes in circumstances indicate the carrying
amounts may not be recoverable. When such conditions exist, management
estimates the future cash flows from operations or disposition. If the
estimated undiscounted future cash flows are less than the carrying amount of
the asset, an adjustment to reduce the carrying amount would be recorded, and
an impairment loss would be recognized. The Operating Unit does not believe
that there is an impairment of such assets.
 
INTANGIBLE ASSETS
 
  Intangible assets are amortized using the straight-line method over the
estimated useful lives of the related assets as follows:

(10) SUBSEQUENT EVENT
 
  On June 30, 1998, Central Ohio and Insight Communications Company, L.P.
(Insight) entered into a Contribution Agreement (the Contribution Agreement)
pursuant to which Central Ohio will contribute to a newly formed subsidiary (a
limited liability company) of Central Ohio (the Operating Company)
substantially all of the assets and liabilities comprising the Operating Unit,
and Insight will contribute $10 million in cash to the Operating Company. As a
result of this Contribution Agreement, Central Ohio will own 25% of the non-
voting common equity and Insight will own 75% of the non-voting common equity
of the Operating Company, subject to possible adjustments pursuant to the
Contribution Agreement. Central Ohio will also own two separate series of
voting preferred equity (a $140 preferred equity interest and a $30 million
preferred equity interest) of the Operating Company; the voting preferred
equity interest will provide for distributions to Central Ohio equal in amount
to the payments on the senior and senior discount notes described below.
Insight or an affiliate will serve as the manager of the Operating Company.
 
  The closing of the Contribution Agreement is conditioned upon, among other
things, the private placement of $140 million senior notes by Central Ohio and
Phoenix Associates (a related entity) and the private placement of $30 million
of senior discount notes by the majority shareholder of Central Ohio.

                NOTES TO INTERIM CONDENSED FINANCIAL STATEMENTS
 
                                 JUNE 30, 1998
                                  (UNAUDITED)
 
(1) GENERAL
 
  The results of operations for the interim periods shown are not necessarily
indicative of the results to be expected for the fiscal year. In the opinion
of Management, the information contained herein reflects all adjustments
necessary to make a fair statement of the results for the three and six months
ended June 30, 1998 and 1997. All such adjustments are of a normal recurring
nature.
 
(2) BUSINESS ORGANIZATION AND PURPOSE
 
  Central Ohio Cable System Operating Unit (the Operating Unit), an operating
unit within Coaxial Communications of Central Ohio, Inc. (Central Ohio),
operates a cable television system which provides basic and expanded cable
services to homes in Columbus, Ohio and surrounding areas. The Operating
Unit's financial statements include only those assets, liabilities, revenues
and expenses directly related to the cable television system to be contributed
(see Note 7).
 
(3) ACCOUNTING POLICIES
 
  Note 2 to the Notes to Financial Statements in the Operating Unit's 1997
Financial Statements summarizes the Operating Unit's significant accounting
policies.
 
(4) INCOME TAXES
 
  The Operating Unit is an operating unit within Central Ohio, which is a
Subchapter S corporation. Therefore, each shareholder reports his distributive
share of income or loss on his respective income tax returns. As a result, the
Operating Unit does not provide for Federal or state income taxes in its
accounts.
 
(5) RELATED PARTY TRANSACTIONS
 
  The Operating Unit has a receivable from a related party as of June 30, 1998
and December 31, 1997 of $98,461 and $98,584, respectively, relating to the
leasing of fiber optic facilities.
 
  The Operating Unit was charged home office expenses of approximately
$336,000 and $731,000 for the three and six months ended June 30, 1998 and
$379,000 and $703,000 for the three and six months ended June 30, 1997
(included in selling and administrative expenses). Home office expenses
include billings for legal fees, management fees, salaries, travel and other
management expenses for services provided by an affiliated services company.
 
  The Operating Unit pays rent to a partnership owned by Central Ohio's
shareholders for two facilities. Total charges for rent were approximately
$99,500 in 1997, $72,000 in 1996 and $72,000 in 1995.
 
(6) COMMITMENTS AND CONTINGENCIES
 
  The Operating Unit is party in or may be affected by various matters under
litigation. Management believes that the ultimate outcome of these matters
will not have a significant adverse effect on either the Operating Unit's
future results of operations or financial position.
 
  Capital expenditures for the Operating Unit for 1998 are expected to be
approximately $5,515,000.

         NOTES TO INTERIM CONDENSED FINANCIAL STATEMENTS--(CONTINUED)
 
(7) SUBSEQUENT EVENT
 
  On June 30, 1998, Central Ohio and Insight Communications Company, L.P.
(Insight) entered into a Contribution Agreement (the Contribution Agreement)
pursuant to which Central Ohio will contribute to a newly formed subsidiary (a
limited liability company) of Central Ohio (the Operating Company)
substantially all of the assets and liabilities comprising the Operating Unit,
and Insight will contribute $10 million in cash to the Operating Company. As a
result of this Contribution Agreement, Central Ohio will own 25% of the non-
voting common equity and Insight will own 75% of the non-voting common equity
of the Operating Company, subject to possible adjustments pursuant to the
Contribution Agreement. Central Ohio will also own two separate series of
voting preferred equity of the Operating Company; the voting preferred equity
interest will provide for distributions to Central Ohio equal in amount to the
payments on the senior and subordinated debt described below. Insight or an
affiliate will serve as the manager of the Operating Company.
 
  The closing of the Contribution Agreement is conditioned upon, among other
things, the private placement of $140 million senior notes by Central Ohio and
Phoenix Associates (a related entity) and the private placement of $30 million
of subordinated debt by the majority shareholder of Central Ohio.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders of
 Coaxial Communications of Central Ohio, Inc.
 
  We have audited the accompanying balance sheets of Coaxial Communications of
Central Ohio, Inc. (an Ohio corporation) as of December 31, 1997 and 1996, and
the related statements of operations and changes in shareholders' equity and
cash flows for each of the three years in the period ended December 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements
based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Coaxial Communications of
Central Ohio, Inc. as of December 31, 1997 and 1996, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                          DECEMBER 31, 1997 AND 1996
 
(1) BUSINESS ORGANIZATION AND PURPOSE
 
  Coaxial Communications of Central Ohio, Inc. (Central Ohio or the Company),
an Ohio corporation, operates a cable television system which provides basic
and expanded cable services to homes in Columbus, Ohio and surrounding areas.
Central Ohio has 2,000 shares of common stock authorized and 1,080 shares
issued and outstanding. The 1,080 outstanding shares are owned by three
individuals. The shares have a stated value of $1 per share.
 
  Other related entities owned or controlled by the majority shareholder of
Central Ohio include Phoenix Associates (Phoenix), Coaxial Communications of
Southern Ohio, Inc. (Southern Ohio), Coaxial Associates of Columbus I
(Columbus I), Coaxial Associates of Columbus II (Columbus II), Paxton Cable
Television, Inc. (Paxton Cable) and Paxton Communications, Inc. (Paxton
Communications).
 
  Central Ohio, as joint and several issuer, with Phoenix, Southern Ohio,
Columbus I and Columbus II, of the note payable described in Note 7(b)
provides the funding that will allow Phoenix to repay its share of the notes
payable, as Phoenix has no operations.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CASH
 
  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.
 
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 VALUES
 
  In December 1991, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 107, "Disclosures about Fair Value of
Financial Instruments," which requires disclosure of fair value information
about both on- and off- balance sheet financial instruments for which it is
practicable to estimate that value.
 
  The carrying amounts of current assets and liabilities approximate their
fair market value because of the immediate or short-term maturity of these
financial instruments. The fair value of related party receivables and
payables are not determinable. The carrying amounts of the loan agreement
debt, including term loans and revolving credit loans, approximate fair value
as the underlying instruments are at variable rates that reprice frequently.
 
  The carrying amounts and related estimated fair values for the Company's
remaining financial instruments are as follows:

<PAGE>
 
                 COAXIAL COMMUNICATIONS OF CENTRAL OHIO, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  The fair value of the interest rate swaps is based upon the estimated amount
that the Company would receive or pay to terminate the swap agreement at the
reporting date, taking into consideration current interest rates and the
creditworthiness of the counterparties.
 
DERIVATIVE FINANCIAL INSTRUMENTS
 
  During 1995, the Company adopted Statement of Financial Accounting Standards
No. 119 (SFAS No. 119), "Disclosure about Derivative Financial Instruments and
Fair Value of Financial Instruments." SFAS No. 119 requires that a distinction
be made between derivative financial instruments held or issued for trading
purposes and derivative instruments held for purposes other than trading,
including hedging. The Company utilizes derivative financial instruments for
hedging purposes to reduce exposure to adverse changes in interest rates. The
amounts to be paid or received related to these transactions are recognized,
on an accrual basis, over the life of the hedged instrument as an adjustment
to interest expense. The related amounts payable to, or receivable from, the
counterparties are included in prepaid expenses and other current assets. The
fair value of the swap agreements is not recognized in the combined financial
statements, since they are accounted for as hedges. Disclosures required by
SFAS No. 119 are shown in Note 10.
 
OPERATING REVENUE RECOGNITION
 
  Service fees are recorded in the month cable television and pay television
services are provided to subscribers. Connection fees are charges for the
hook-up of new customers and are recognized when billed on the subscriber's
first bill. Unearned revenues are recorded as advance subscriber deposits in
the accompanying financial statements.
 
CONCENTRATION OF CREDIT RISK
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of trade accounts receivable. The Company's
customer base consists of a number of homes concentrated in the central Ohio
area. The Company continually monitors the exposure for credit losses and
maintain allowances for anticipated losses. As of December 31, 1997, the
Company had no significant concentrations of credit risk.
 
MATERIAL, SUPPLIES AND CONSTRUCTION INVENTORIES
 
  Material, supplies and construction inventories are stated at the lower of
cost (first-in, first-out basis) or market.
 
PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost, while maintenance and repairs are
expensed as incurred. Upon retirement or disposal of assets, the cost and
related accumulated depreciation and amortization are removed from the balance
sheet, and any gain or loss is reflected in earnings. Depreciation and
amortization are provided using the straight-line method over the estimated
useful lives of the related assets as follows:

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

</TABLE>
 
  The Company internally constructs certain CATV systems. Construction costs
capitalized include payroll, fringe benefits and other overhead costs
associated with construction activity.
 
  The Company reviews its property, plant and equipment and other long term
assets when events or changes in circumstances indicate the carrying amounts
may not be recoverable. When such conditions exist, management estimates the
future cash flows from operations or disposition. If the estimated
undiscounted future

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
cash flows are less than the carrying amount of the asset, an adjustment to
reduce the carrying amount would be recorded, and an impairment loss would be
recognized. The Company does not believe that there is an impairment of such
assets.
 
INTANGIBLE ASSETS
 
  Intangible assets are amortized using the straight-line method over the
estimated useful lives of the related assets as follows:
 
<TABLE>
<CAPTION>
                                                                       YEARS
                                                                    ------------
   <S>                                                              <C>
   Franchise rights................................................   7 to 15
   Deferred loan acquisition costs................................. Term of debt
</TABLE>
 
  Deferred loan acquisition costs relate to costs, primarily legal fees and
bank facility fees incurred to negotiate and secure bank loans (see Note 7).
These costs are being amortized on a straight-line basis over the life of the
applicable loans. The amount amortized, approximately $549,000, $508,000 and
$508,000 in 1997, 1996 and 1995, respectively, is included in interest
expense.
 
HOME OFFICE EXPENSES
 
  Home office expenses of approximately $1,498,000, $1,697,000 and $1,695,000
in 1997, 1996 and 1995 (included in selling and administrative expenses)
include billings for legal fees, management fees, salaries, travel and other
management expenses for services provided by an affiliated services company.
 
ADVERTISING COSTS
 
  Advertising costs are expensed as incurred. Advertising expense primarily
for campaign and telemarketing-related efforts was approximately $1,025,000,
$1,060,000 and $817,000 in 1997, 1996 and 1995, respectively.
 
EARNINGS PER SHARE
 
  Basic and Diluted earnings per share were calculated as net income divided
by the weighted average number of common shares outstanding.
 
(3) INCOME TAXES
 
  Central Ohio is a Subchapter S corporation. Therefore, each shareholder
reports his distributive share of income or loss on his respective income tax
returns. As a result, the Company does not provide for Federal or state income
taxes in its accounts. In the event that the Subchapter S corporation election
is terminated, deferred taxes related to book and tax temporary differences
would be required to be reflected in the financial statements.
 
(4) THRIFT PLAN
 
  The Company has an employer sponsored Thrift Plan (the Plan) for employees
having at least one full year of service. Employees can contribute up to 6% of
their salary to the Plan which is matched 50% by the Company. Employees can
also contribute an additional 1% to 10% which is not matched by the Company.
Employees become fully vested in matching contributions after 5 years. There
is no partial vesting. The Company's contributed approximately $133,000,
$111,000 and $120,000 to the Plan in 1997, 1996 and 1995, respectively. The
Thrift Plan will not be contributed as part of the Contribution Agreement

(a) In November, 1982, Columbus I and Columbus II exchanged all of their
    assets and certain liabilities with Central Ohio for common stock and
    notes. These notes bear interest at a rate of 20% and had been scheduled
    to mature on October 31, 1997. A portion of these notes ($5,066,764) had
    been assigned and was payable to the former Limited Partners of Columbus I
    and Columbus II as part of their consideration when they sold their
    partnership interest to the General Partners. The notes payable to former
    Limited Partners were paid in 1997. The maturity date of the remaining
    notes (payable to Columbus I and Columbus II) was extended to October 31,
    2002. Interest expense was approximately $1,498,100, $1,600,000 and
    $1,600,000 in 1997, 1996 and 1995, respectively, related to the notes
    payable.
 
(b) On November 15, 1994, Central Ohio, Phoenix, Southern Ohio, Columbus I and
    Columbus II (collectively referred to as the borrowers), executed a loan
    agreement with a lead bank and several other financial institutions to
    replace an existing loan agreement. On May 12, 1998, the loan agreement
    was amended. The loan agreement provides for principal term loans up to
    $150,000,000 and revolving credit loans up to $23,000,000 ($22,000,000
    after the May 12, 1998 amendment). Principal payments on the term loans
    are due in 19 quarterly installments of $250,000 beginning March 15, 1995,
    and a final quarterly installment for the remaining balance outstanding.
    Revolving credit loans are payable at December 31, 1999. Interest on the
    outstanding balances under the loan agreement is payable at either a) a
    rate comparable to prime rate as defined in the agreement plus 2%, or b)
    at a rate comparable to the Eurodollar rate as defined in the agreement
    plus 3.25% depending on the borrowers' option at the time the loan is
    drawn. These margins have been amended to 2.25% and 3.50%, respectively,
    effective March 3, 1997. Interest rates on borrowings outstanding at
    December 31, 1997 range from 9.25% to 9.47%. The termination date of the
    loan agreement is December 31, 1999. Interest expense was approximately
    $2,284,500, $1,920,500 and $1,785,300 in 1997, 1996 and 1995,
    respectively. The letters of credit discussed in Note 8 aggregating
    $1,100,000 decrease availability of borrowings under the loan agreement.
    Unused and unreserved borrowing availability under the loan agreement at
    December 31, 1997 was $5,900,000.
 
  A revolving credit commitment fee of .5% is paid on the average daily
  balance available for draw under the revolving credit loan.
 
  The funds borrowed under the loan agreement were allocated to the following
  entities as of December 31, 1997:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The loans are secured by substantially all of the borrowers' assets and are
  joint and several obligations of the borrowers. Significant notes
  receivable are pledged as collateral. In addition, the shareholders and
  partners of the borrowers have pledged all of their shares and partnership
  interests in the borrowers. The proceeds of the loans were used to
  refinance existing bank and other notes payable, make capital distributions
  to the shareholders and partners, and to finance capital expenditures of
  Central Ohio and Southern Ohio. Repayment of the Phoenix debt is dependent
  upon funding from Central Ohio or Southern Ohio as Phoenix has no
  operations.
 
  Among other covenants, the borrowers must comply with restrictive covenants
  relating to leverage coverage, interest coverage and cash ratios. In
  addition, repayments of principal on the loan are required if certain
  conditions relating to asset dispositions, new debt, distributions or
  excess cash flow are met. The borrowers are in compliance with these
  covenants, as amended, as of December 31, 1997.
 
  The borrowers are entitled to issue letters of credit for general corporate
  purposes or to replace existing letters of credit up to an amount not
  exceeding $2,000,000. The borrowers pay a fee equal to 2% per annum of the
  amount available for draw under any letters of credit issued. Any draws on
  letters of credit issued will be made a part of the outstanding balance on
  the revolving credit loan.
 
  Due to loan agreement requirements, the borrowers have entered into
  interest rate swap agreements to reduce the impact of changes in interest
  rates on the outstanding principal balances (see Notes 9 and 10).
 
(c) In January 1996, Central Ohio issued an unsecured note payable to a key
    officer for deferred compensation. The officer retired in 1997. See Note
    13 for related discussion.
 
(8) LETTERS OF CREDIT
 
  The Company, with the other borrowers defined in Note 7, have letters of
credit for the benefit of certain program suppliers and former Limited
Partners. At December 31, 1997 and 1996, the aggregate value of these letters
of credit for the benefit of certain program suppliers was $1,100,000 and
$850,000, respectively. At December 31, 1997 and 1996, the aggregate value of
these letters of credit for the benefit of the former Limited Partners was $0
(due to final settlement with Limited Partners) and $1,140,775, respectively.
 
(9) FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
 
  The Company, with the other borrowers defined in Note 7, become a party to
financial instruments with off-balance-sheet risk in the normal course of
business in managing its interest rate risk. These financial instruments
include interest rate swap agreements, and previously, forward interest rate
agreements and interest rate caps. These instruments involve, to varying
degrees, elements of credit and interest rate risk in excess of the amount
recognized on the Company's balance sheets. The contract or notional amounts
of these instruments reflect the extent of involvement the Company has in
particular classes of financial instruments.
 
  The Company has utilized interest rate caps, interest rate swap agreements
and forward interest rate agreements as hedge instruments to reduce exposure
to adverse changes in interest rates. The notional amounts of these
instruments do not represent exposure to credit loss. Risks associated with
these types of financial instruments arise from the movement of interest rates
and failure of the other party to the transaction to meet its obligation. Note
10 provides additional disclosures on the Company's derivative financial
instruments.
 
  The following table shows the contract or notional amount of the Company's
off-balance-sheet financial instruments at December 31, 1997 and 1996.

(10) DERIVATIVE FINANCIAL INSTRUMENTS
 
  The Company, with the other borrowers defined in Note 7, holds derivative
financial instruments only for purposes other than trading. The Company's
primary objective is the "hedging" or management of interest rate risk
associated with its long-term debt. The two parties to an interest rate swap
agreement agree to exchange, at particular intervals, payment streams
calculated on a specified notional amount, with one stream based on a floating
interest rate and the other stream based on a fixed interest rate. The swaps
were entered into in order to reduce the overall interest rate sensitivity of
the Company. These interest rate swap agreements are the standard
fixed/floating type of swap agreements, whereby the Company pays a fixed rate
(i.e., swapped rate) and receives a floating rate from the counterparty based
upon the LIBOR index. All of the interest rate swaps are treated as hedges,
and accordingly, are accounted for on the same basis as the underlying asset
or liability being hedged. The amounts to be paid or received related to
derivative financial instruments are recognized on an accrual basis, over the
estimated life of the hedged instrument, as an adjustment to interest expense.
The counterparty to all of the Company's off-balance-sheet financial
instrument agreements is the lead bank on the loan agreement.
 
  The following table summarizes the interest rate swap agreements:

</TABLE>
 
  In accordance with the loan agreement, the Company also had previously
purchased interest rate caps to aid in the management of its interest rate
risk. The seller of these caps was obligated to pay the Company the amount, if
any, by which a specified market interest rate exceeded the fixed cap applied
to the notional amount. There were no interest rate cap agreements in effect
at December 31, 1997, and the initial contract costs related to previous
interest rate cap agreements were fully amortized as of December 31, 1997.
 
(11) OPERATING LEASE AGREEMENTS
 
  Central Ohio leases land for tower locations, office equipment, office
space, vehicles and the use of utility poles under various operating lease

(13) COMMITMENTS AND CONTINGENCIES
 
  Through December 31, 1995, Central Ohio had an agreement with a key officer
to defer certain discretionary compensation amounts each year. On January 1,
1996, Central Ohio entered into an unsecured note payable to this officer in
the amount of $2,343,947, which represented all vested deferred compensation
at December 31, 1995. During 1996, this officer earned additional
discretionary compensation in the amount of $193,140. This amount was added to
the unpaid December 31, 1996 principal balance of the above note and the
payment amount was adjusted accordingly. As of December 31, 1997 and 1996, the
outstanding balance of the note was $2,046,880 and $2,302,688, respectively.
The note is payable in equal monthly installments of $21,322 plus accrued
interest at the prime rate (8.50% at December 31, 1997), and matures in
December 2005. Interest expense on the note was $184,810 and $185,005 in 1997
and 1996, respectively.
 
  The Company is party in or may be affected by various matters under
litigation. Management believes that the ultimate outcome of these matters
will not have a significant adverse effect on either the Company's future
results of operation or financial position.
 
  Capital expenditures for Central Ohio for 1998 is expected to be
approximately $5,515,000.
 
  The Company has an executive severance program and an incentive bonus plan
that entitles certain employees to receive compensation, as defined, in an
event of a change in control of the Company.
 
(14) SUBSEQUENT EVENT
 
  On June 30, 1998, Central Ohio and Insight Communications Company, L.P.
(Insight) entered into a Contribution Agreement (the Contribution Agreement)
pursuant to which Central Ohio will contribute to a newly formed subsidiary (a
limited liability company) of Central Ohio (the Operating Company)
substantially all of the assets and liabilities comprising the cable system,
and Insight will contribute $10 million in cash to the Operating

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
Company. As a result of this Contribution Agreement, Central Ohio will own 25%
of the non-voting common equity and Insight will own 75% of the non-voting
common equity of the Operating Company, subject to possible adjustments
pursuant to the Contribution Agreement. Central Ohio will also own two
separate series (a $140 million preferred equity interest and a $30 million
preferred equity interest) of voting preferred equity of the Operating
Company; the voting preferred equity interest will provide for distributions
to Central Ohio equal in amount to the payments on the senior and senior
discount notes described below. Insight or an affiliate will serve as the
manager of the Operating Company.
 
  The closing of the Contribution Agreement is conditioned upon, among other
things, the private placement of $140 million senior notes by Central Ohio and
Phoenix (which will replace Central Ohio's and Phoenix's notes payable to
banks) and the private placement of $30 million of senior discount notes by
the majority shareholder of Central Ohio.
 
  In conjunction with this transaction, there will be a settlement or net
distribution of related party receivables and payables. The impact on Central
Ohio at December 31, 1997 would be a decrease to shareholder's equity of
approximately $53.2 million.
 
  The pro forma balances of Central Ohio's total assets and shareholders
equity if this Contribution Agreement, private placement, and the settlement
of related party balances, that will happen in conjunction with the
transactions, would have occurred as of December 31, 1997 are as follows:

provides the funding that will allow Phoenix to repay its share of the note
payable, as Phoenix has no operations.
 
(3) ACCOUNTING POLICIES
 
  Note 2 to the Notes to Financial Statements in the Company's December 31,
1997 Financial Statements summarize the Company's significant accounting
policies.
 
EARNINGS PER SHARE
 
  Basic and Diluted earnings per share were calculated as net income divided
by the weighted average number of common shares outstanding.
 
(4) INCOME TAXES
 
  Central Ohio is a Subchapter S corporation. Therefore, each shareholder
reports his distributive share of income or loss on his respective income tax
returns. As a result, the Company does not provide for Federal or state income
taxes in its accounts. In the event that the Subchapter S corporation election
is terminated, deferred taxes related to book and tax temporary differences
would be required to be reflected in the financial statements.
 
(5) RELATED PARTY TRANSACTIONS
 
  Central Ohio incurred home office expenses of approximately $336,000 and
$731,000 for the three and six months ended June 30, 1998 and $379,000 and
$703,000 for the three and six months ended June 30, 1997 (included in selling
and administrative expenses). Home office expenses include billings for legal
fees, management fees, salaries, travel and other management expenses for
services provided by an affiliated services company.
 
  Central Ohio also pays rent to a partnership owned by Central Ohio's
shareholders for two facilities. Total charges for rent were approximately
$27,000 and $54,000 for the three and six months ended June 30, 1998 and
$27,000 and $45,500 for the three and six and months ended June 30, 1997.

(a) In November, 1982, Columbus I and Columbus II exchanged all of their
    assets and certain liabilities with Central Ohio for common stock and
    notes. These notes bear interest at a rate of 20% and had been scheduled
    to mature on October 31, 1997. A portion of these notes ($5,066,764) had
    been assigned and was payable to the former Limited Partners of Columbus I
    and Columbus II as part of their consideration when they sold their
    partnership interest to the General Partners. The notes payable to former
    Limited Partners were paid in 1997. The maturity date of the remaining
    notes (payable to Columbus I and Columbus II) was extended to October 31,
    2002. Interest expense was approximately $146,700 and $293,300 for the
    three and six months ended June 30, 1998 and $400,000 and $800,000 for the
    three and six months ended June 30, 1997.

(b) On November 15, 1994, Central Ohio, Phoenix, Southern Ohio, Columbus I and
    Columbus II (collectively referred to as the borrowers), executed a loan
    agreement with a lead bank and several other financial institutions to
    replace an existing loan agreement. On May 12, 1998, the loan agreement
    was amended. The loan agreement provides for principal term loans up to
    $150,000,000 and revolving credit loans up to $22,000,000. Principal
    payments on the term loans are due in 19 quarterly installments of
    $250,000 beginning March 15, 1995, and a final quarterly installment for
    the remaining balance outstanding. Revolving credit loans are payable at
    December 31, 1999. Interest on the outstanding balances under the loan
    agreement is payable at either a) a rate comparable to prime rate as
    defined in the agreement plus 2%, or b) at a rate comparable to the
    Eurodollar rate as defined in the agreement plus 3.25% depending on the
    borrowers' option at the time the loan is drawn. These margins have been
    amended to 2.25% and 3.50%, respectively, effective March 3, 1997.
    Interest rates on borrowings outstanding at June 30, 1998 range from 9.16%
    to 10.75%. The termination date of the loan agreement is December 31,
    1999. Interest expense was $596,856 and $1,186,285 for the three and six
    months ended June 30, 1998 and $567,530 and $1,110,178 for the three and
    six months ended June 30, 1997. There are letters of credit aggregating
    $1,100,000 for the benefit of certain program suppliers that decrease
    availability of borrowings under the loan agreement. Unused and unreserved
    borrowing availability under the loan agreement at June 30, 1998 was
    $2,400,000.
 
  A revolving credit commitment fee of .5% is paid on the average daily
  balance available for draw under the revolving credit loan.
 
  The funds borrowed under the loan agreement were allocated to the following
entities as of June 30, 1998:

  The loans are secured by substantially all of the borrowers' assets and are
  joint and several obligations of the borrowers. Significant notes
  receivable are pledged as collateral. In addition, the shareholders and
  partners of the borrowers have pledged all of their shares and partnership
  interests in the borrowers. The proceeds of the loans were used to
  refinance existing bank and other notes payable, make capital distributions
  to the shareholders and partners, and to finance capital expenditures of
  Central Ohio and Southern Ohio. Repayment of the Phoenix debt is dependent
  upon funding from Central Ohio or Southern Ohio as Phoenix has no
  operations.
 
  Among other covenants, the borrowers must comply with restrictive covenants
  relating to leverage coverage, interest coverage and cash ratios. In
  addition, repayments of principal on the loan are required if certain
  conditions relating to asset dispositions, new debt, distributions or
  excess cash flow are met. The borrowers are in compliance with these
  covenants, as amended, as of June 30, 1998.
 
  The borrowers are entitled to issue letters of credit for general corporate
  purposes or to replace existing letters of credit up to an amount not
  exceeding $2,000,000. The borrowers pay a fee equal to 2% per annum of the
  amount available for draw under any letters of credit issued. Any draws on
  letters of credit issued will be made a part of the outstanding balance on
  the revolving credit loan.
 
  Due to loan agreement requirements, the borrowers have entered into
  interest rate swap agreements to reduce the impact of changes in interest
  rates on the outstanding principal balances (see Notes 7 and 8).
 
(c) In January 1996, Central issued an unsecured note payable to a key officer
    for deferred compensation. The officer retired in 1997. See Note 9 for
    related discussion.

(7) FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
 
  The Company, with the other borrowers defined in Note 6, became a party to
financial instruments with off-balance-sheet risk in the normal course of
business in managing its interest rate risk. These financial instruments
include interest rate swap agreements, and previously, forward interest rate
agreements and interest rate caps. These instruments involve, to varying
degrees, elements of credit and interest rate risk in excess of the amount
recognized on the Company's balance sheets. The contract or notional amounts
of these instruments reflect the extent of involvement the Company has in
particular classes of financial instruments.
 
  The Company has utilized interest rate caps, interest rate swap agreements
and forward interest rate agreements as hedge instruments to reduce exposure
to adverse changes in interest rates. The notional amounts of these
instruments do not represent exposure to credit loss. Risks associated with
these types of financial instruments arise from the movement of interest rates
and failure of the other party to the transaction to meet its obligation. Note
8 provides additional disclosures on the Company's derivative financial
instruments.
 
(8) DERIVATIVE FINANCIAL INSTRUMENTS
 
  The Company, with the other borrowers defined in Note 6, may hold derivative
financial instruments only for purposes other than trading. The Company's
primary objective is the "hedging" or management of interest rate risk
associated with its long-term debt. The two parties to an interest rate swap
agreement agree to exchange, at particular intervals, payment streams
calculated on a specified notional amount, with one stream based on a floating
interest rate and the other stream based on a fixed interest rate. The swaps
were entered into in order to reduce the overall interest rate sensitivity of
the Company. These interest rate swap agreements are the standard
fixed/floating type of swap agreements, whereby the Company pays a fixed rate
(i.e., swapped rate) and receives a floating rate from the counterparty based
upon the LIBOR index. All of the interest rate swaps are treated as hedges,
and accordingly, are accounted for on the same basis as the underlying asset
or liability being hedged. The amounts to be paid or received related to
derivative financial instruments are recognized on an accrual basis, over the
estimated life of the hedged instrument, as an adjustment to interest expense.
The counterparty to all of the Company's off-balance-sheet financial
instrument agreements is the lead bank on the loan agreement. The Company held
no derivative financial instruments at June 30, 1998.
 
(9) COMMITMENTS AND CONTINGENCIES
 
  Through December 31, 1995, Central Ohio had an agreement with a key officer
to defer certain discretionary compensation amounts each year. On January 1,
1996, Central Ohio entered into an unsecured note payable to this officer in
the amount of $2,343,947, which represented all vested deferred compensation
at December 31, 1995. During 1996, this officer earned additional
discretionary compensation in the amount of $193,140. This amount was added to
the unpaid December 31, 1996 principal balance of the above note and the
payment amount was adjusted accordingly. As of June 30, 1998 and December 31,
1997, the outstanding balance of the note was $1,918,950 and $2,046,880,
respectively. The note is payable in equal monthly installments of $21,322
plus accrued interest at the prime rate (8.50% at June 30, 1998), and matures
in December 2005. Interest expense on the note was $41,684 and $84,727 for the
three and six months ended June 30, 1998 and $47,121 and $94,646 for the three
and six months ended June 30, 1997.
 
  The Company is party in or may be affected by various matters under
litigation. Management believes that the ultimate outcome of these matters
will not have a significant adverse effect on either the Company's future
results of operation or financial position.
 
  Capital expenditures for Central Ohio for 1998 is expected to be
approximately $5,515,000.
 
  The Company has an executive severance program and an incentive bonus plan
that entitles certain employees to receive compensation, as defined, in an
event of a change in control of the Company.

(10) SUBSEQUENT EVENT
 
  On June 30, 1998, Central Ohio and Insight Communications Company, L.P.
(Insight) entered into a Contribution Agreement (the Contribution Agreement)
pursuant to which Central Ohio will contribute to a newly formed subsidiary (a
limited liability company) of Central Ohio (the Operating Company)
substantially all of the assets and liabilities comprising the cable system,
and Insight will contribute $10 million in cash to the Operating Company. As a
result of this Contribution Agreement, Central Ohio will own 25% of the non-
voting common equity and Insight will own 75% of the non-voting common equity
of the Operating Company, subject to possible adjustments pursuant to the
Contribution Agreement. Central Ohio will also own two separate series of
voting preferred equity (a $140 million preferred equity interest and a $30
million preferred equity interest) of the Operating Company; the voting
preferred equity interest will provide for distributions to Central Ohio equal
in amount to the payments on the senior and senior discount notes described
below. Insight or an affiliate will serve as the manager of the Operating
Company.
 
  The closing of the Contribution Agreement is conditioned upon, among other
things, the private placement of $140 million senior notes by Central Ohio and
Phoenix (which will replace Central Ohio's and Phoenix's notes payable to
banks) and the private placement of $30 million of senior discount notes by
the majority shareholder of Central Ohio.
 
  In conjunction with this transaction, there will be a settlement or net
distribution of related party receivables and payables. The impact on Central
Ohio at December 31, 1997 would be a decrease to shareholders' equity of
approximately $53.2 million.
 
  The pro forma balances of Central Ohio's total assets and shareholders'
equity if this Contribution Agreement, private placement, and the settlement
of related party balances, that will happen in conjunction with the
transactions, would have occurred as of December 31, 1997 are as follows:

  In addition, this transaction will trigger the executive severance program
and incentive bonus plan described in Note 9 above. Approximately $1.2 million
of compensation could be paid under these plans.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the General Partners of
 Phoenix Associates:
 
  We have audited the accompanying balance sheets of Phoenix Associates (a
Florida partnership) as of December 31, 1997 and 1996, and the related
statements of operations and changes in partners' deficit and cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Phoenix Associates as of
December 31, 1997 and 1996, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.
 
  As indicated in Note 1, Phoenix Associates has no operations. It's ability
to satisfy debt and other obligations is dependent upon funding from related
entities, which are under the common control of the owners of Phoenix
Associates.

                         NOTES TO FINANCIAL STATEMENTS
 
                          DECEMBER 31, 1997 AND 1996
 
(1) BUSINESS ORGANIZATION AND PURPOSE
 
  Phoenix Associates (Phoenix or the Company) is a Florida general partnership
organized for the primary purpose of purchasing promissory notes, mortgages,
deeds of trust, debt securities and other types of securities, and purchasing
and acquiring rights in any loan agreements or other documents relating to
those securities. Phoenix Associates has no operations. Its ability to satisfy
debt and other obligations is dependent upon funding from related entities,
which are under the common control of the owners of Phoenix Associates. As
discussed in Note 5, the bank borrowings are joint and several obligations of
five related entities.
 
  Phoenix consists of three individual partners who share profits and losses
in the ratio of 67 1/2%, 22 1/2% and 10%, respectively.
 
  Other related entities owned or controlled by the majority partner of
Phoenix include Coaxial Communications of Central Ohio, Inc. (Central Ohio),
Coaxial Communications of Southern Ohio, Inc. (Southern Ohio), Coaxial
Associates of Columbus I (Columbus I), Coaxial Associates of Columbus II
(Columbus II), Paxton Cable Television, Inc. (Paxton Cable) and Paxton
Communications, Inc. (Paxton Communications).
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
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 VALUES
 
  In December 1991, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 107, "Disclosures about Fair Value of
Financial Instruments," which requires disclosure of fair value information
about both on- and off-balance sheet financial instruments for which it is
practicable to estimate that value.
 
  The carrying amounts of current assets and liabilities approximate their
fair market value because of the immediate or short-term maturity of these
financial instruments. The fair value of related party receivables and
payables are not determinable. The carrying amounts of the notes payable (loan
agreement debt) approximate fair value as the underlying instruments are at
variable rates that reprice frequently.
 
DERIVATIVE FINANCIAL INSTRUMENTS
 
  During 1995, the Company adopted Statement of Financial Accounting Standards
No. 119 (SFAS No. 119), "Disclosure about Derivative Financial Instruments and
Fair Value of Financial Instruments." SFAS No. 119 requires that a distinction
be made between derivative financial instruments held or issued for trading
purposes and derivative instruments held for purposes other than trading,
including hedging. The Company utilizes derivative financial instruments for
hedging purposes to reduce exposure to adverse changes in interest rates. The
amounts to be paid or received related to these transactions are recognized,
on an accrual basis, over the life of the hedged instrument as an adjustment
to interest expense. The related amounts payable to, or receivable from, the
counterparties are included in prepaid expenses and other current assets. The
fair value of the swap agreements is not recognized in the financial
statements, since they are accounted for as hedges. Disclosures required by
SFAS No. 119 are shown in Note 8.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
(3) INCOME TAXES
 
  Phoenix is a general partnership. Therefore, each partner reports his
distributive share of income or loss on his respective income tax returns. As
a result, the Company does not provide for Federal or state income taxes in
its accounts.
 
(4) RELATED PARTY TRANSACTIONS
 
  As of December 31, 1997 and 1996, Phoenix has advances due from two general
partners of $768,000.
 
  Phoenix has advanced funds to and received advances from related entities
for working capital and for debt service. These amounts bear interest at 5.66%
as of December 31, 1997. Phoenix recognized interest income of approximately
$358,800 in 1997, $511,200 in 1996 and $500,700 in 1995 and recognized
interest expense of approximately $4,025,800 in 1997, $5,027,600 in 1996 and
$4,079,000 in 1995 relating to such advances.
 
  Advances to and from related entities as of December 31, 1997 and 1996 are

(a) The $2,348,892 due from Columbus I represents a note, including past due
    interest that was added to the principal, which were purchased from CNA
    Financial Corporation on November 24, 1982. Interest is payable to Phoenix
    monthly at an annual rate of 20% of the face amount of the notes
    receivable. Phoenix recognized interest income of approximately
    $1,138,000, $1,212,800 and $1,212,800 in 1997, 1996 and 1995,
    respectively, related to the note receivable. The principal is due and
    payable to Phoenix on October 31, 2002.
(b) The $443,773 due from Columbus II represents a note, including past due
    interest that was added to the principal, which were purchased from CNA
    Financial Corporation on November 24, 1982. Interest is payable to Phoenix
    monthly at an annual rate of 20% of the face amount of the notes

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Amounts in excess of purchase price represent the difference between the
face amount and the accrued interest receivable on the notes purchased and the
price paid. The amounts in excess of purchase price will be recognized when
the principal due on the notes is received, net of any costs associated with
final settlement.
 
  In 1997, the notes receivable from former Limited Partners of Columbus I and
Columbus II matured. The "amounts in excess of purchase price" relating to
these notes were realized at the time of settlement. The financial statements
reflect gain on the settlement of the notes of $3,315,337 (amounts in excess
of purchase price).
 
  These related entities are under the control of the partners of Phoenix. The
partners have represented that substantially all of these amounts will be
settled among the parties (see Note 9).

(a) On November 15, 1994, Phoenix, Central Ohio, Southern Ohio, Columbus I and
    Columbus II (collectively referred to as the borrowers), executed a loan
    agreement with a lead bank and several other financial institutions to
    replace an existing loan agreement. On May 12, 1998, the loan agreement
    was amended. The loan agreement provides for principal term loans up to
    $150,000,000 and revolving credit loans up to $23,000,000 ($22,000,000
    after the May 12, 1998 amendment). Principal payments on the term loans
    are due in 19 quarterly installments of $250,000 beginning March 15, 1995,
    and a final quarterly installment for the remaining balance outstanding.
    Revolving credit loans are payable at December 31, 1999. Interest on the
    outstanding balances under the loan agreement is payable at either a) a
    rate comparable to prime rate as defined in the agreement plus 2%, or b)
    at a rate comparable to the Eurodollar rate as defined in the agreement
    plus 3.25% depending on the borrowers' option at the time the loan is
    drawn. These margins have been amended to 2.25% and 3.50%, respectively,
    effective March 3, 1997. Interest rates on borrowings outstanding at
    December 31, 1997 range from 9.25% to 9.47%. The termination date of the
    loan agreement is December 31, 1999. Interest expense for 1997, 1996 and
    1995 was $9,855,120, $9,495,420 and $10,301,191, respectively. The letters
    of credit discussed in Note 6 aggregating $1,100,000 decrease availability
    of borrowings under the loan agreement. Unused and unreserved borrowing
    availability under the loan agreement at December 31, 1997 was $5,900,000.
 
  A revolving credit commitment fee of .5% is paid on the average daily
  balance available for draw under the revolving credit loan.

    The loans are secured by substantially all of the borrowers' assets and
  are joint and several obligations of the borrowers. Significant notes
  receivable are pledged as collateral. In addition, the shareholders and
  partners of the borrowers have pledged all of their shares and partnership
  interests in the borrowers. The proceeds of the loans were used to
  refinance existing bank and other notes payable, make capital distributions
  to the shareholders and partners, and to finance capital expenditures of
  Central Ohio and Southern Ohio. Repayment of the Phoenix debt is dependent
  upon funding from Central Ohio or Southern Ohio.
 
    Among other covenants, the borrowers must comply with restrictive
  covenants relating to leverage coverage, interest coverage and cash ratios.
  In addition, repayments of principal on the loan are required if certain
  conditions relating to asset dispositions, new debt, distributions or
  excess cash flow are met. The borrowers are in compliance with these
  covenants, as amended, as of December 31, 1997.
 
    The borrowers are entitled to issue letters of credit for general
  corporate purposes or to replace existing letters of credit up to an amount
  not exceeding $2,000,000. The borrowers pay a fee equal to 2% per annum of
  the amount available for draw under any letters of credit issued. Any draws
  on letters of credit issued will be made a part of the outstanding balance
  on the revolving credit loan.
 
    Due to loan agreement requirements, the borrowers have entered into
  interest rate swap agreements to reduce the impact of changes in interest
  rates on the outstanding principal balances (see Notes 7 and 8).
 
(b) In November 1980, Phoenix issued an unsecured promissory note to the
    Estate of Morris Telechansky. Monthly principal installments of $1,253
    commencing December, 1992 were due through 1997. The note bore interest at
    a rate of 1.25% above the prevailing $100,000 Certificate of Deposit rate.
    This note was paid in full during fiscal year 1997.
 
(c) In November 1980, Phoenix issued an unsecured promissory note to the
    Estate of Zorabel Telechansky. Monthly combined principal and interest
    installments of $1,260 commencing October, 1992 were due through November,
    1997 and include interest at 10.5%. This note was paid in full during
    fiscal year 1997.
 
(6) LETTERS OF CREDIT
 
  The Company, with the borrowers defined in Note 5, has letters of credit for
the benefit of certain program suppliers and former Limited Partners (see Note
4). At December 31, 1997 and 1996, the aggregate value of these letters of
credit for the benefit of certain program suppliers was $1,100,000 and
$850,000, respectively. At December 31, 1997 and 1996, the aggregate value of
these letters of credit for the benefit of the former Limited Partners was $0
(due to final settlement with Limited Partners) and $1,140,775, respectively.
 
(7) FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
 
  The Company, with the borrowers defined in Note 5, become a party to
financial instruments with off-balance-sheet risk in the normal course of
business in managing its interest rate risk. These financial instruments

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
include interest rate swap agreements, and previously, forward interest rate
agreements and interest rate caps. These instruments involve, to varying
degrees, elements of credit and interest rate risk in excess of the amount
recognized on the Company's balance sheets. The contract or notional amounts
of these instruments reflect the extent of involvement the Company has in
particular classes of financial instruments.
 
  The Company has utilized interest rate caps, interest rate swap agreements
and forward interest rate agreements as hedge instruments to reduce exposure
to adverse changes in interest rates. The notional amounts of these
instruments do not represent exposure to credit loss. Risks associated with
these types of financial instruments arise from the movement of interest rates
and failure of the other party to the transaction to meet its obligation. Note
8 provides additional disclosures on the Company's derivative financial
instruments.
 
  The following table shows the contract or notional amount of the Company's
off-balance-sheet financial instruments at December 31, 1997 and 1996.

(8) DERIVATIVE FINANCIAL INSTRUMENTS
 
  The Company, with the borrowers as defined in Note 5, currently hold
derivative financial instruments only for purposes other than trading. The
Company's primary objective is the "hedging" or management of interest rate
risk associated with its long-term debt. The two parties to an interest rate
swap agreement agree to exchange, at particular intervals, payment streams
calculated on a specified notional amount, with one stream based on a floating
interest rate and the other stream based on a fixed interest rate. The swaps
were entered into in order to reduce the overall interest rate sensitivity of
the Company. These interest rate swap agreements are the standard
fixed/floating type of swap agreements, whereby the Company pays a fixed rate
(i.e., swapped rate) and receive a floating rate from the counterparty based
upon the LIBOR index. All of the interest rate swaps are treated as hedges,
and accordingly, are accounted for on the same basis as the underlying asset
or liability being hedged. The amounts to be paid or received related to
derivative financial instruments are recognized on an accrual basis, over the
estimated life of the hedged instrument, as an adjustment to interest expense.
The counterparty to all of the Company's off-balance-sheet financial
instrument agreements is the lead bank on the loan agreement.
 
  The following table summarizes the interest rate swap agreements:

</TABLE>
 
  In accordance with the loan agreement, the Company also had previously
purchased interest rate caps to aid in the management of its interest rate
risk. The seller of these caps was obligated to pay the Company the amount, if
any, by which a specified market interest rate exceeded the fixed cap applied
to the notional amount. There were no interest rate cap agreements in effect
at year-end, and the initial contract costs related to previous interest rate
cap agreements were fully amortized as of December 31, 1997.
 
(9) SUBSEQUENT EVENT
 
  Phoenix, with Central Ohio, is currently contemplating the offering,
initially through a private placement, of $140 million of senior notes. These
senior notes would replace Phoenix's and Central Ohio's notes payable to
banks.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In connection with the offering, Central Ohio and Insight Communications,
L.P. (Insight) entered into a Contribution Agreement (the Contribution
Agreement) pursuant to which Central Ohio will contribute to a newly formed
subsidiary (a limited liability company) of Central Ohio (the Operating
Company) substantially all of the assets and liabilities comprising the cable
system of Central Ohio, and Insight will contribute $10 million in cash to the
Operating Company. As a result of this Contribution Agreement, Central Ohio
will own 25% of the non-voting common equity and Insight will own 75% of the
non-voting common equity of the Operating Company, subject to possible
adjustment pursuant to the Contribution Agreement. Central Ohio will also own
two separate series of voting preferred equity (a $140 million preferred
equity interest and a $30 million preferred equity interest) of the Operating
Company; the voting preferred equity interest will provide for distributions
to Central Ohio equal in amount to the payments on the senior and senior
discount notes (described below).
 
  The closing of the Contribution Agreement is conditioned upon, among other
things, the private placement of the senior notes by Phoenix and Central Ohio
and the private placement of $30 million of senior discount notes by the
majority shareholder of Central Ohio.
 
  In conjunction with this transaction, there will be a settlement or net
distribution of related party receivables and payables. The impact on Phoenix
at December 31, 1997 would be an increase to partners' equity of approximately
$69.3 million.
 
  The pro forma balance of Phoenix's partners' deficit if the private
placement and the settlement of related party balances, that will happen in
conjunction with the transactions, would have occurred as of December 31, 1997
is as follows:

(1) GENERAL
 
  The results of operations for the interim periods shown are not necessarily
indicative of the results to be expected for the fiscal year. In the opinion
of Management, the information contained herein reflects all adjustments
necessary to make a fair statement of the results for the three and six months
ended June 30, 1998 and 1997. All such adjustments are of a normal recurring
nature.
 
(2) BUSINESS ORGANIZATION AND PURPOSE
 
  Phoenix Associates (Phoenix or the Company) is a Florida general partnership
organized for the primary purpose of purchasing promissory notes, mortgages,
deeds of trust, debt securities and other types of securities, and purchasing
and acquiring rights in any loan agreements or other documents relating to
those securities. Phoenix Associates has no operations. Its ability to satisfy
debt and other obligations is dependent upon funding from related entities,
which are under the common control of the owners of Phoenix Associates. As
discussed in Note 6, the bank borrowings are joint and several obligations of
five related entities.
 
  Phoenix consists of three individual partners who share profits and losses
in the ratio of 67 1/2%, 22 1/2% and 10%, respectively.
 
  Other related entities owned or controlled by the majority partner of
Phoenix include Coaxial Communications of Central Ohio, Inc. (Central Ohio),
Coaxial Communications of Southern Ohio, Inc. (Southern Ohio), Coaxial
Associates of Columbus I (Columbus I), Coaxial Associates of Columbus II

(a) The $2,348,892 due from Columbus I represents a note, including past due
    interest that was added to the principal, which were purchased from CNA
    Financial Corporation on November 24, 1982. Interest is payable to Phoenix
    monthly at an annual rate of 20% of the face amount of the notes
    receivable. Phoenix recognized interest income of approximately $117,400
    and $234,900 for the three and six months ended June 30, 1998 and $303,200
    and $606,400 for the three and six months ended June 30, 1997, related to
    the note receivable. The principal is due and payable to Phoenix on
    October 31, 2002.
(b) The $443,773 due from Columbus II represents a note, including past due
    interest that was added to the principal, which were purchased from CNA
    Financial Corporation on November 24, 1982. Interest is payable to Phoenix
    monthly at an annual rate of 20% of the face amount of the notes
    receivable. Phoenix recognized interest income of approximately $22,200
    and $44,400 for the three and six months ended June 30, 1998 and $77,600
    and $155,300 for the three and six months ended June 30, 1997, related to
    the note receivable. The principal is due and payable to Phoenix on
    October 31, 2002.
 
  Amounts in excess of purchase price represent the difference between the
face amount and the accrued interest receivable on the notes purchased and the
price paid. The amounts in excess of purchase price will be recognized when
the principal due on the notes is received, net of any costs associated with
final settlement.
 
  These related entities are under the control of the partners of Phoenix. The
shareholders have represented that substantially all of these amounts will be
settled among the parties (see Note 9).
 
(6) NOTES PAYABLE
 
  On November 15, 1994, Phoenix, Central Ohio, Southern Ohio, Columbus I and
Columbus II (collectively referred to as the borrowers), executed a loan
agreement with a lead bank and several other financial institutions to replace
an existing loan agreement. On May 12, 1998, the loan agreement was amended.
The loan agreement provides for principal term loans up to $150,000,000 and
revolving credit loans up to $22,000,000. Principal payments on the term loans
are due in 19 quarterly installments of $250,000 beginning March 15, 1995, and

         NOTES TO INTERIM CONDENSED FINANCIAL STATEMENTS--(CONTINUED)
 
final quarterly installment for the remaining balance outstanding. Revolving
credit loans are payable at December 31, 1999. Interest on the outstanding
balances under the loan agreement is payable at either a) a rate comparable to
prime rate as defined in the agreement plus 2%, or b) at a rate comparable to
the Eurodollar rate as defined in the agreement plus 3.25% depending on the
borrowers' option at the time the loan is drawn. These margins have been
amended to 2.25% and 3.50%, respectively, effective March 3, 1997. Interest
rates on borrowings outstanding at June 30, 1998 range from 9.16% to 10.75%.
The termination date of the loan agreement is December 31, 1999. Interest
expense was $2,451,600 and $4,900,400 for the three and six months ended June
30, 1998 and $2,450,500 and $4,799,400 for the three and six months ended June
30, 1997. There are letters of credit aggregating $1,100,000 for the benefit
of certain program suppliers that decrease availability of borrowings under
the loan agreement. Unused and unreserved borrowing availability under the
loan agreement at June 30, 1998 was $2,400,000.
 
  A revolving credit commitment fee of .5% is paid on the average daily
balance available for draw under the revolving credit loan.
 
  The funds borrowed under the loan agreement were allocated to the following
entities as of June 30, 1998:

  The loans are secured by substantially all of the borrowers' assets and are
joint and several obligations of the borrowers. Significant notes receivable
are pledged as collateral. In addition, the shareholders and partners of the
borrowers have pledged all of their shares and partnership interests in the
borrowers. The proceeds of the loans were used to refinance existing bank and
other notes payable, make capital distributions to the shareholders and
partners, and to finance capital expenditures of Central Ohio and Southern
Ohio. Repayment of the Phoenix debt is dependent upon funding from Central
Ohio or Southern Ohio.
 
  Among other covenants, the borrowers must comply with restrictive covenants
relating to leverage coverage, interest coverage and cash ratios. In addition,
repayments of principal on the loan are required if certain conditions
relating to asset dispositions, new debt, distributions or excess cash flow
are met. The borrowers are in compliance with these covenants, as amended, as
of June 30, 1998.
 
  The borrowers are entitled to issue letters of credit for general corporate
purposes or to replace existing letters of credit up to an amount not
exceeding $2,000,000. The borrowers pay a fee equal to 2% per annum of the
amount available for draw under any letters of credit issued. Any draws on
letters of credit issued will be made a part of the outstanding balance on the
revolving credit loan.
 
  Due to loan agreement requirements, the borrowers have entered into interest
rate swap agreements to reduce the impact of changes in interest rates on the
outstanding principal balances (see Notes 7 and 8).
 
(7) FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
 
  The Company, with the borrowers defined in Note 6, become a party to
financial instruments with off-balance-sheet risk in the normal course of
business in managing its interest rate risk. These financial instruments
 
                                     F-53
<PAGE>
 
                              PHOENIX ASSOCIATES
 
         NOTES TO INTERIM CONDENSED FINANCIAL STATEMENTS--(CONTINUED)
 
include interest rate swap agreements, and previously, forward interest rate
agreements and interest rate caps. These instruments involve, to varying
degrees, elements of credit and interest rate risk in excess of the amount
recognized on the Company's balance sheets. The contract or notional amounts
of these instruments reflect the extent of involvement the Company has in
particular classes of financial instruments.
 
  The Company has utilized interest rate caps, interest rate swap agreements
and forward interest rate agreements as hedge instruments to reduce exposure
to adverse changes in interest rates. The notional amounts of these
instruments do not represent exposure to credit loss. Risks associated with
these types of financial instruments arise from the movement of interest rates
and failure of the other party to the transaction to meet its obligation. Note
8 provides additional disclosures on the Company's derivative financial
instruments.
 
(8) DERIVATIVE FINANCIAL INSTRUMENTS
 
  The Company, with the borrowers as defined in Note 6, may hold derivative
financial instruments only for purposes other than trading. The Company's
primary objective is the "hedging" or management of interest rate risk
associated with its long-term debt. The two parties to an interest rate swap
agreement agree to exchange, at particular intervals, payment streams
calculated on a specified notional amount, with one stream based on a floating
interest rate and the other stream based on a fixed interest rate. The swaps
were entered into in order to reduce the overall interest rate sensitivity of
the Company. These interest rate swap agreements are the standard
fixed/floating type of swap agreements, whereby the Company pays a fixed rate
(i.e., swapped rate) and receives a floating rate from the counterparty based
upon the LIBOR index. All of the interest rate swaps are treated as hedges,
and accordingly, are accounted for on the same basis as the underlying asset
or liability being hedged. The amounts to be paid or received related to
derivative financial instruments are recognized on an accrual basis, over the
estimated life of the hedged instrument, as an adjustment to interest expense.
The counterparty to all of the Company's off-balance-sheet financial
instrument agreements is the lead bank on the loan agreement. The Company held
no derivative financial instruments at June 30, 1998.
 
(9) SUBSEQUENT EVENT
 
  Phoenix, with Central Ohio, is currently contemplating the offering,
initially through a private placement, of $140 million of senior notes. These
senior notes would replace Phoenix's and Central Ohio's notes payable to
banks.
 
  In connection with the offering, Central Ohio and Insight Communications,
L.P. (Insight) entered into a Contribution Agreement (the Contribution
Agreement) pursuant to which Central Ohio will contribute to a newly formed
subsidiary (a limited liability company) of Central Ohio (the Operating
Company) substantially all of the assets and liabilities comprising the cable
system of Central Ohio, and Insight will contribute $10 million in cash to the
Operating Company. As a result of this Contribution Agreement, Central Ohio
will own 25% of the non-voting common equity and Insight will own 75% of the
non-voting common equity of the Operating Company, subject to possible
adjustment pursuant to the Contribution Agreement. Central Ohio will also own
two separate series of voting preferred equity (a $140 million preferred
equity interest and a $30 million preferred equity interest) of the Operating
Company; the voting preferred equity interest will provide for distributions
to Central Ohio equal in amount to the payments on the senior and senior
discount notes (described below).
 
  In conjunction with this transaction, there will be a settlement or net
distribution of related party receivables and payables. The impact on Phoenix
at December 31, 1997 would be an increase to partner's equity of approximately
$69.3 million.
 
  The closing of the Contribution Agreement is conditioned upon, among other
things, the private placement of the senior notes by Phoenix and Central Ohio
and the private placement of $30 million of senior discount notes by the
majority shareholder of Central Ohio.

                    NOTES TO PRO FORMA FINANCIAL STATEMENTS
 
 (1) Contribution of $10.0 million cash from Insight.
 
 (2) Fair value of property at 3770 East Livingston Avenue contributed
     pursuant to Contribution Agreement.
 
 (3) Capitalization of the estimated deferred loan acquisition costs related
     to the offering of Senior Notes.
 
 (4) Reflects the write-off of net deferred loan acquisition costs related to
     the Chase Credit Facility which is being purchased and restructured with
     the proceeds from the Offering.
 
 (5) As part of the financing and restructuring, certain related party
     balances will be settled at the closing of the Offering. Approximately
     $4,531,000 of Bank notes payable will be assumed by Central in connection
     with the settlement of certain related party balances.
 
 (6) As part of the financing and restructuring, deferred compensation owed to
     a former executive is to be paid at the closing of the Offering.
 
 (7) Purchase and restructuring of the Chase Credit Facility, and issuance of
     Senior Notes in connection with the Offering. The debt consists of the
     allocation of principal amount of $34.4 million to Coaxial and $105.6
     million to Phoenix pursuant to the Offering. Approximately $3.7 million
     will be distributed to the shareholders of Central, who will then
     contribute that amount to Phoenix to pay for loan acquisition costs.
 
 (8) Represents estimated cost savings as a result of contractual programming
     rates from Insight. In addition Insight Ohio is required by the Employee
     Transition Agreement to reduce headcount and benefits as a result of
     position duplication within the accounting and finance departments, as
     well as other redundant management positions. Each individual has been
     specifically identified in the Employee Transition Agreement. These
     accounting and finance functions will be replaced with services provided
     by Insight going forward. The estimated cost savings associated with
     these actions are as follows:

    performance because it is commonly used in the cable television industry
    to analyze and compare cable television companies on the basis of
    operating performance, leverage, and liquidity. However, EBITDA is not
    intended to be a performance measure that should be regarded as an
    alternative to, or more meaningful than, either operating income or net
    income as an indicator of operating performance or cash flows as a measure
    of liquidity, as determined in accordance with generally accepted
    accounting principles. EBITDA, as computed by management, is not
    necessarily comparable to similarly titled amounts of other companies.
 
(18) System Cash Flow represents EBITDA plus home office prior to system
     acquisition and EBITDA plus management fees after the system acquisition.
     Management believes that System Cash Flow is a meaningful measure of
     performance because it is commonly used in the cable television industry
     to analyze and compare cable television companies on the basis of
     operating performance, leverage and liquidity. However, System Cash Flow
     is not intended to be a performance measure that should be regarded as an

(19) Approximately $1.1 million of cash will be used for severance payments
     and approximately 3.3 million will be used to pay expenses associated
     with structure costs.

months ended June 30, 1998 (the "Pro Forma Statements of Operations" and,
together with the Pro Forma Balance Sheet, the "Pro Forma Financial
Statements") give effect to the Financing Plan and certain other adjustments.
The unaudited pro forma adjustments are based upon available information and
certain assumptions that management believes are reasonable. The Pro Forma

have actually been obtained had such transactions been completed as of the
assumed dates and for the periods presented, or which may be obtained in the
future.

System Operating Unit" included elsewhere herein, adjusted to give effect to
the Financing Plan and certain other adjustments as if they had occurred on
January 1, 1997. The Pro Forma Balance Sheet and Pro Forma Statement of
Operations as of and for the six months ended June 30, 1998 have been derived
from the unaudited financial statements of "Central Ohio Cable System
Operating Unit" included elsewhere herein, adjusted to give effect to the
Financing Plan and certain other adjustments as if they had occurred on
January 1, 1998 with respect to the Pro Forma Statements of Operations, and on
June 30, 1998 with respect to the Pro Forma Balance Sheet.
 
  The Pro Forma Financial Statements and the accompanying notes should be read
in conjunction with the financial statements of "Central Ohio Cable System
Operating Unit" together with the related notes thereto, included elsewhere

     pursuant to Contribution Agreement.
 
 (3) Recording of Preferred Interests issued to Coaxial.

     well as other redundant management positions. Each individual has been
     specifically identified in the Employee Transition Agreement. These
     accounting and finance functions will be replaced with services provided

 (8) Depreciation of contributed property at 3770 East Livingston Avenue.
 
 (9) Represents the preferred distribution on the Preferred Interests. The
     preferred distribution is 10% on the Series A Preferred Interest and 12
     7/8% on the Series B Preferred Interest.
 
(10) EBITDA represents net income before depreciation, amortization, interest
     expense, other expenses and gain on settlement of limited partner notes.
     Management believes that EBITDA is a meaningful measure of performance
     because it is commonly used in the cable television industry to analyze
     and compare cable television companies on the basis of operating
     performance, leverage and liquidity. However, EBITDA is not intended to
     be a performance measure that should be regarded as an alternative to, or
     more meaningful than, either operating income or net income as an
     indicator of operating performance or cash flows as a measure of
     liquidity, as determined in accordance with generally accepted accounting
     principles. EBITDA, as computed by management, is not necessarily
     comparable to similarly titled amounts of other companies.
 
(11) System Cash Flow represents EBITDA plus home office prior to system
     acquisition and EBITDA plus management fees after the system acquisition.
     Management believes that System Cash Flow is a meaningful measure of
     performance because it is commonly used in the cable television industry
     to analyze and compare cable television companies on the basis of
     operating performance, leverage and liquidity. However, System Cash Flow
     is not intended to be a performance measure that should be regarded as an
     alternative to, or more meaningful than, either operating income or net
     income as an indicator of operating performance or cash flows as a
     measure of liquidity, as determined in accordance with generally accepted
     accounting principles. System Cash Flow, as computed, by the management,
     is not necessarily comparable to similarly titled amounts of other
     companies. See the financial statements, including the Statement of Cash
     Flows, included elsewhere herein. System Cash Flow, as computed by
     management, is not necessarily comparable to similarly titled amounts of
     other companies.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  (A) Coaxial Communications of Central Ohio, Inc. ("Coaxial")
 
  Division (E) of Section 1701.13 of the Ohio Revised Code addresses
indemnification by an Ohio corporation and provides in pertinent part as
follows:
 
    A corporation may indemnify or agree to 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, other than an action by or in the right
  of the corporation, by reason of the fact that he is or was a director,
  officer, employee, or agent of the corporation, or is or was serving at the
  request of the corporation as a director, trustee, officer, employee,
  member, manager, or agent of another corporation, domestic or foreign,
  nonprofit or for profit, a limited liability company, or a partnership,
  joint venture, trust, or other enterprise, against expenses, including
  attorney's fees, judgments, fines, and amounts paid in settlement actually
  and reasonably incurred by him in connection with such action, suit, or
  proceeding, if he acted in 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 of any criminal action or proceeding, if he had no
  reasonable cause to believe his conduct was unlawful.
 
  Sections 5.01 and 5.02 of the Regulations (By-Laws) of Coaxial govern the
indemnification of officers and directors of Coaxial as follows:
 
    Section 5.01. Mandatory Indemnification. The corporation shall indemnify
  any officer or director of the corporation 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 (including, without limitation, any action threatened or
  instituted by or in the right of the corporation), by reason of the fact
  that he is or was a director, officer, employee or agent of the
  corporation, or is or was serving at the request of the corporation as a
  director, trustee, officer, employee or agent of another corporation
  (domestic or foreign, nonprofit or for profit), partnership, joint venture,
  trust or other enterprise, against expenses (including, without limitation,
  attorney's fees, filing fees, court reporters' fees and transcript costs),
  judgments, fines and amounts paid in settlement actually and reasonably
  incurred by him in connection with such action, suit or proceeding if he
  acted in 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, he had no reasonable cause to believe his
  conduct was unlawful.
 
    Section 5.02. Court-Approved Indemnification. Anything contained in the
  Regulations (By-Laws) or elsewhere to the contrary notwithstanding, the
  corporation shall not indemnify any officer or director of the corporation
  who was a party to any completed action or suit instituted by or in the
  right of the corporation to procure a judgment in its favor by reason of
  the fact that he is or was a director, officer, employee or agent of the
  corporation, or is or was serving at the request of the corporation as a
  director, trustee, officer, employee or agent of another corporation
  (domestic or foreign, nonprofit or for profit), partnership, joint venture,
  trust or other enterprise, in respect of any claim, issue or matter
  asserted in such action or suit as to which he shall have been adjudged to
  be liable for gross negligence or misconduct (other than negligence) in the
  performance of his duty to the corporation unless and only to the extent
  that the Court of Common Pleas of Franklin County, Ohio or the court in
  which such action or suit was brought shall determination upon application
  that, despite such adjudication of liability, and in view of all the
  circumstances of the case, he is fairly and reasonably entitled to such
  indemnity as such Court of Common Pleas or such other court shall deem
  proper.
 
 
  Sections 4.1 through 4.9 of the Close Corporation Agreement of Coaxial,
effective as of August 21, 1998, provide additional indemnification provisions
applicable to the officers and directors of Coaxial. Section 2.2 of such Close
Corporation Agreement provides that, to the extent that the Regulations of
Coaxial are inconsistent
 
                                     II-1
<PAGE>
 
with any provision of the Close Corporation Agreement, the Close Corporation
Agreement shall, to the extent permitted by the Ohio Revised Code, control. To
the extent that the Regulations of Coaxial are not inconsistent with the Close
Corporation Agreement, the Regulations govern.
 
  (B) Insight Communications of Central Ohio, LLC ("Insight Ohio").
 
  Section 18-108 of the Delaware Limited Liability Company Act (the "Delaware
LLC Act") empowers a limited liability company to indemnify and hold harmless
any member or manager or other person from and against any and all claims and
demands whatsoever; subject to such standards and restriction, if any, set
forth in the operating agreement.
 
  Section 11.1 of Insight Ohio's Operating Agreement (the "Operating
Agreement") provides as follows:
 
   Insight Ohio shall indemnify, defend and hold harmless each member of
  Insight Ohio and its members, partner, officers, directors shareholders,
  employees, and agents, the employees, officers and agents of Insight Ohio,
  the Principals (as defined in the Operating Agreement), and the
  Representatives (as defined in the Operating Agreement) (collectively,
  "Indemnified Persons") from any liability, loss, or damage incurred by the
  Indemnified Person by reason of any act performed or omitted to be
  performed by the Indemnified Person in connection with the business of
  Insight Ohio (including, in the case of Insight Holdings of Ohio, LLC
  ("Insight"), any such act in connection with the management of the
  Shareholders (as defined in the Operating Agreement) pursuant to the
  management agreements between Shareholders and Insight, or arising by
  reason of Insight's status as manager of the Shareholders), including costs
  and attorneys' fees (which attorneys' fees may be paid as incurred) and any
  amounts expended in the settlement of any claims of liability, loss or
  damage; provided, however, that if the liability, loss, damage or claim
  arises out of any action or inaction of an Indemnified Person,
  indemnification shall not be available if the action or inaction
  constitutes fraud, gross negligence, breach of fiduciary duty (which shall
  not be construed to encompass mistakes in judgment or any breach of any
  Indemnified Person's duty of care that did not constitute gross negligence)
  willful misconduct, or breach of the Operating Agreement by the Indemnified
  Person; and provided, further, however, that indemnification shall be
  recoverable only from the assets of Insight Ohio and not from any assets of
  the members of Insight Ohio. Insight Ohio may pay for insurance covering
  liability of the Indemnified Persons for negligence in operation of Insight
  Ohio's affairs.

ITEM 22. UNDERTAKINGS
 
  Coaxial Communications of Central Ohio, Inc., Phoenix Associates and Insight
Communications of Central Ohio, Inc. (the "Registrants") hereby undertake:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement: (i) to include any
  prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii)
  to reflect in the prospectus any facts or events arising after the
  effective date of the Registration Statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Commission
  pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
  price represent no more than a 20% change in the maximum aggregate offering
  price set forth in the "Calculation of Registration Fee" table in the
  effective registration statement; (iii) to include any material information
  with respect to the plan of distribution not previously disclosed in the
  Registration Statement or any material change to such information in the
  Registration Statement;
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof; and
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
                                     II-4
<PAGE>
 
  The undersigned Registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through
the date of responding to the request.
 
  The undersigned Registrants hereby undertake 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.
 
  The undersigned Registrants hereby undertake as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),
the Registrants undertake that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
 
  The Registrants undertake that every prospectus (i) that is filed pursuant
to the immediately preceding paragraph, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in
connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the Registration Statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the foregoing provisions, or otherwise, the
Registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrants of expenses incurred or paid by a director, officer
or controlling person of the Registrants 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
Registrants will, unless in the opinion of their counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by them is against
public policy as expressed in the Securities Act of 1933 and will be governed
by the final adjudication of such issue.
 
  The undersigned Registrants hereby undertake that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  the Registration Statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the Registrants pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part
  of this Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, 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.

Governmental Permits, required to conduct the business of the System and operate
the System lawfully and in the same manner as the business of the System is
currently conducted and the System is currently operated by Central. Each
Franchise is in full force and effect in accordance with its terms. Central is
the authorized legal holder of each Franchise. Except as disclosed on Schedule

obligations under any Franchise. All appropriate requests for renewal under the
Communications Act have been filed with the appropriate Franchising Authorities
within the time frame required by each Franchise and pursuant to applicable
Legal Requirements. Central has no reason to believe that under existing Legal
Requirements, any of the Franchises would not be renewed by the granting
authority in the ordinary course. Central has not made any commitments (oral or
written) to any Franchising Authorities with respect to the System other than
those contained in the Franchises.

      5.8  Governmental Permits.

operations of the System. There are no pending or, to Central's Knowledge,
threatened condemnation proceedings, special assessments, proceedings for
changes in zoning, lawsuits, or administrative actions that could adversely
affect Central's current use or occupancy of any Real Property.  All Real
Property has full legal and practical access to public roads or streets and
facilities necessary for the operation of the System.  To Central's Knowledge,
there are no leases, subleases, licenses, concessions, or other agreements,
whether written or oral, granting to any Person the right to use or occupy any
of the Real Property that would impair the Company's ability to use such Real
Property after the Closing for its intended purpose.

principles).  No default exists under any Assumed Contract. Central has not, nor
has any other party to a Contract, given or received any notice that any party
to any Assumed Contract intends to terminate or not to renew such Assumed
Contract or amend the terms thereof and, subject to receipt of the Consents, the
consummation of the transactions contemplated by this Agreement is not likely to

statements of accounts, or royalty payments or any notice, inquiry, or claim
from any other Person to the effect that the conduct of the business or
operations of the System has infringed, or as currently conducted infringes, on
the intellectual property rights of any Person.

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

     8.1  Consents.
          -------- 

          (a) Central shall use commercially reasonable efforts to obtain as
expeditiously as possible all Consents required for the performance of its
obligations under this Agreement and the documents contemplated hereby.  No such
Consent shall include any condition or qualification that would impose terms or
conditions that are materially more burdensome than those set forth in the
Franchise, Governmental Permit, or other Assumed Contract that is the subject of
the Consent, unless otherwise agreed to by Insight.  Any instrument evidencing
any Consent shall be in form and substance reasonably satisfactory to Insight.

          (b) Central will submit an FCC Form 394 to each Franchising Authority
that granted any of the Franchises (excluding any Franchising Authority the
consent of which is not required to assign to the Company the Franchise issued
by such Franchising Authority) within fifteen days after Central receives from
Insight all information regarding Insight that is required to complete such FCC
Form 394.

          (c) Nothing in this Agreement shall require Central to make any
expenditure or payment of funds or give any other consideration in order to
obtain any Consent required for the performance of their obligations under this
Agreement and the documents contemplated hereby, except for fees of attorneys
for Central, filing fees, and other reasonable fees or out-of-pocket costs (for
example, application fees) imposed by any Franchising Authority, Governmental
Authority or other third party and any costs required to remedy any item of
breach by Central with the terms of any Franchise, Governmental Permit, or other
Contract.

          (d) Insight will cooperate fully with Central in obtaining any
necessary Consents, but Insight will not be required (1) to make any payment to
any Person or Franchising Authority from which such Consent is sought or (2) to
accept any terms, conditions, or obligations that are materially more burdensome
than those currently contained in any Franchise, Governmental Permit, or Assumed
Contract as a condition to obtaining any Consent.  Insight may participate with
Central in negotiations with Franchising Authorities and other third parties
with respect to the Consents.  Insight will not, without the prior written
consent of Central, seek amendments or modifications to the Franchises or other
Assumed Contracts.

          (e) Insight shall promptly furnish to any Franchising Authority or
other third party any information regarding Insight, including financial
information concerning Insight and other 

                                      -28-
<PAGE>
 
information relating to the cable and other operations of Insight (other than
information that Insight reasonably deems to be proprietary), that such
Franchising Authority or other third party may reasonably require in connection
with obtaining any Consent, and Insight shall promptly furnish to Central a copy
of any such information provided to such Franchising Authority or other third
party. Each of Insight and Central shall use reasonable efforts to ensure that
its appropriate officers and employees shall be available to attend, as the
Franchising Authority may reasonably request, any scheduled hearings or meetings
in connection with obtaining such Consent.

     8.2  Cooperation.
          ----------- 

     The parties to this Agreement will cooperate fully with each other and
their respective counsel and accountants in connection with any actions required
to be taken as part of their respective obligations under this Agreement, and
each party shall execute such other documents as may be reasonably necessary and
desirable to the implementation and consummation of this Agreement, and
otherwise shall use its commercially reasonable efforts to consummate the
transactions contemplated by this Agreement and to fulfill its obligations
hereunder.

     8.3  Deferred Contributions.
          ---------------------- 

     If on the date specified for the Closing pursuant to Section 10.1(a), any
Service Area is not a Transferable Service Area, then, notwithstanding any other
provision of this Agreement, the following provisions shall apply:

          (a) At the Closing, Central shall contribute to the Company, only
those Assets that do not relate solely to a Service Area that is not a
Transferable Service Area (including any Assets, such as head-ends and business
offices and the Real Property Interests and equipment related thereto, that may
relate both to Transferable Service Areas and Service Areas that are not
Transferable Service Areas).  The Assets that are not contributed to the Company
at the Closing in accordance with the preceding sentence are referred to in this
Section 8.3 as the "Retained Assets."  From and after the Closing, Central shall
retain the Retained Assets, and Central shall contribute the Retained Assets to
the Company in accordance with the terms of this Section 8.3.

          (b)  At the Closing:

               (1) All conveyancing documents, certificates, and other documents
contemplated by this Agreement to be delivered at the Closing shall be in the
form and substance provided for in this Agreement with such modifications as are
necessary or appropriate to reflect the provisions of this Section 8.3 and to
relate only to the Assets being contributed to the Company at the Closing.

               (2) Central and the Company shall enter into a management
agreement (each, a "Management Agreement"), in form and substance reasonably
satisfactory to Insight and Central, which will provide that the Company will
manage the Retained Assets for Central's benefit 

                                      -29-
<PAGE>
 
and the Company will be entitled to receive and retain all revenues, and will be
responsible for all costs and expenses, attributable to the operations of such
Retained Assets after the Closing.

          (c) After the Closing, Central, Insight, and the Company shall
continue to undertake, in accordance with this Agreement, to obtain any Consent
necessary to cause any Service Area that was not a Transferable Service Area on
the Closing Date to become a Transferable Service Area, and the agreements and
obligations of Central and Insight under Section 8.1 shall be fully applicable
in seeking such Consents after the Closing. Central shall give Insight written
notice of the receipt of any Consent necessary to cause any Service Area that
was not a Transferable Service Area on the Closing Date to become a Transferable
Service Area. As soon as practicable after any Service Area that was not a
Transferable Service Area on the Closing Date becomes a Transferable Service
Area, on a date to be specified by Insight, a closing shall be held at which
Central shall contribute to the Company those Retained Assets relating to such
Service Area and the Company and Central shall execute and deliver conveyancing
documents, certificates, and other documents corresponding to those delivered at
the Closing with such modifications as are necessary or appropriate to reflect
the provisions of this Section 8.3 (including the Company's management of the
Retained Assets) and to relate only to the Retained Assets being contributed to
the Company at such closing. Upon such closing, the applicable Management
Agreement will be terminated insofar as it relates to the Retained Assets
transferred at such closing. The value of such Retained Assets is reflected in
the net fair market value of the Assets as calculated in accordance with this
Agreement, and any such contribution by Central shall not increase the amount of
capital contributions made by Central for purposes of the Operating Agreement.

          (d) If any Retained Assets have not been contributed to the Company
prior to the dissolution of the Company pursuant to the Operating Agreement,
then, upon the dissolution and liquidation of the Company, the Liquidator (as
defined in the Operating Agreement) shall have the authority to sell such
Retained Assets on behalf of Central in connection with the liquidation of the
Company in accordance with the liquidation procedures in the Operating
Agreement.  Upon the consummation of any such sale of the Retained Assets,
Central shall contribute to the Company an amount in cash equal to the net pre-
tax proceeds of such sale, and the Company shall treat such amount as if it were
proceeds from the liquidating sale of assets of the Company.  The right to
receive such net sale proceeds in lieu of the Retained Assets, under the
circumstances described in this Section 8.3(d), is reflected in the net fair
market value of the Assets as calculated in accordance with this Agreement, and
neither such contribution by Central nor Central's failure to contribute the
Retained Assets shall increase or decrease the amount of capital contributions
made by Central for purposes of the Operating Agreement.

     8.4  Confidentiality.
          --------------- 

          (a) Except as and to the extent required by any Legal Requirement or
as provided in Section 8.4(c), each party will keep confidential any information
obtained from the other party in connection with the transactions contemplated
by this Agreement.  If this Agreement is terminated, each party will return to
the other party or destroy all information obtained by such party from the 

                                      -30-
<PAGE>
 
other party in connection with the transactions contemplated by this Agreement.
The obligations of the parties under this Section 8.4(a) will survive the
termination of this Agreement.

          (b) Except as provided in Section 8.4(c), neither party shall publish
any press release or make any other public announcement concerning this
Agreement or the transactions contemplated hereby without the prior written
consent of the other party, which shall not be withheld unreasonably.

          (c) Nothing contained in this Agreement shall prevent either party
from making any filings with Governmental Authorities, including in connection
with any securities filings with any Governmental Authorities or exchanges that,
in its judgment, may be required or advisable in connection with the execution
and delivery of this Agreement or the consummation of the transactions
contemplated hereby.

     8.5  Bulk Sales Law.
          -------------- 

     Insight, for itself and on behalf of the Company, waives compliance by
Central with Article 6 of the Uniform Commercial Code (regarding bulk sales) as
in effect in the states in which the Assets are located and the business of the
System is conducted.

     8.6  Further Assurances.
          ------------------ 

     After the Closing, Central shall take such actions, and execute and deliver
to the Company such further deeds, bills of sale, assignments, or other transfer
documents as, in the opinion of counsel for Insight, may be reasonably necessary
to ensure the full and effective transfer of the Assets to the Company pursuant
to this Agreement.

     8.7  HSR Act.
          ------- 

     Each party to this Agreement has determined that neither such party nor its
ultimate parent entity (within the meaning of the HSR Act) is required to make
any filings with the Department of Justice or the Federal Trade Commission under
the HSR Act in connection with the transactions contemplated by this Agreement.
If either party subsequently determines that any filing under the HSR Act is
required in connection with the transactions contemplated by this Agreement, (a)
each party and its Affiliates will cooperate with the other party in causing
such filing to be made as expeditiously as practicable, (b) each party and its
Affiliates will promptly file, after any request by the Department of Justice or
the Federal Trade Commission and after appropriate negotiation with the
Department of Justice or the Federal Trade Commission of the scope of such
request, any information or documents so requested, and (c) each party will
furnish to other party any correspondence from or to, and notify the other party
of any other communications with, the Department of Justice or the Federal Trade
Commission that relates to the transactions contemplated by this Agreement.

     8.8  Risk of Loss.
          ------------ 

     The risk of any loss, damage, impairment, confiscation, or condemnation of
any of the Assets from any cause whatsoever shall be borne by Central at all
times prior to the Closing and thereafter shall be borne by the Company.

     8.9  Use of Names and Logos.
          ---------------------- 

     For a period of 180 days after Closing, the Company shall be entitled to
use the trademarks, trade names, service marks, service names, logos, and
similar proprietary rights of Central to the extent incorporated in or on the
Assets transferred to the Company at Closing, provided that Insight shall
exercise reasonable efforts to cause the Company to remove all such names,
marks, logos, and similar proprietary rights of Central from such Assets as soon
as reasonably practicable following Closing.

     8.10 Power of Attorney.
          ----------------- 

     At Closing, Central shall grant to the Company the limited, irrevocable
right, in Central's name, place, and stead, as Central's attorney-in-fact, to

provided by the System.  In addition, on or prior to the Closing Date, Central
shall provide written instructions to its lock-box service provider or similar
agents to promptly forward to the Company all such cash, deposits, and checks
that it may receive.  From and after the Closing, Central shall promptly remit
to the Company any payment received by Central on or after the Closing Date in
respect of any accounts receivable of the System as of the Closing.

     8.11 Access to Books and Records.

to Central of its election to terminate this Agreement, on or before July 15,

completing its due diligence, Insight is not satisfied with any matter relating
to the System or the transactions contemplated by this Agreement (including the
Exhibits and Schedules to this Agreement).

     11.5 Escrow Deposit.
          -------------- 

     On or prior to July 15, 1998, if Insight has not terminated this Agreement

          (a) At the Closing, Insight and Central shall jointly instruct the
Escrow Agent to disburse all amounts held by the Escrow Agent pursuant to the
Escrow Agreement, including any 

                                      -38-
<PAGE>
 
interest or other proceeds from the investment of funds held by the Escrow

          (b) If this Agreement is terminated pursuant to this Article 11 and

          (c) If this Agreement is terminated by Central due to Insight's breach

     11.6 Rights on Termination.
          --------------------- 

          (a) If this Agreement is terminated by Central and Section 11.5(c)
applies, then the payment to Central pursuant to Section 11.5(c) shall be
liquidated damages and shall constitute full payment and the exclusive remedy
for any damages suffered by Central by reason of Insight's breach of this
Agreement. Central and Insight agree in advance that actual damages would be
difficult to ascertain and that the amount of the payment to be made to Central
pursuant to Section 11.5(c) is a fair and equitable amount to reimburse Central
for damages sustained due to Insight's breach of this Agreement.

          (b) Upon termination of this Agreement pursuant to this Article 11,

              (1) The transactions contemplated by this Agreement shall be
terminated and abandoned, without further action by Insight or Central.

              (2) Each party shall return to the other party or destroy all
documents and other material received from the other party and relating to the
transactions contemplated by this Agreement, whether received from the other
party before or after the execution of this Agreement.

Agreement with respect to the business of the other party or any of its
Affiliates shall be treated in accordance with Section 8.4(a).

              (4) The provisions of Section 12.2 shall continue in effect.

              (5) Neither party to this Agreement shall have any further
obligation or liability under this Agreement to the other party, or to any of

of the other party, except as provided in this Section 11.6, or otherwise in
this Agreement.

<PAGE>
 
          (c) Following the termination of this Agreement pursuant to this
Article 11, each party agrees to indemnify, defend, and hold harmless the other
party from any liability, loss, or damage incurred by the other party by reason
of any claim made against the other party under this Agreement, in violation of
Section 11.6(b)(5), by any of the members, partners, officers, directors,
shareholders, employees, or agents of the indemnifying party.

     11.7 Specific Performance.
          -------------------- 

     The parties recognize that if Central breaches this Agreement and refuses
to perform under the provisions of this Agreement, monetary damages alone would
not be adequate to compensate Insight for its injury.  Insight shall therefore
be entitled, in addition to any other remedies that may be available, including
money damages, to obtain specific performance of the terms of this Agreement.
If any action is brought by Insight to enforce this Agreement, Central shall
waive the defense that there is an adequate remedy at law.

consent of the other party hereto, except that Insight may, without the consent
of Central, prior to Closing, assign all of Insight's rights and delegate all of

substance reasonably satisfactory to Central, pursuant to which such assignee
shall assume all obligations of Insight under this Agreement. Upon such
assignee's execution and delivery to Central of such assignment and assumption
agreement, Insight shall be released from its obligations hereunder, except that

Section 11.5, and Insight shall execute and deliver to Central and the

     This Agreement, and all Schedules and Exhibits hereto (which are hereby
incorporated herein), and all documents and certificates to be delivered by the
parties pursuant hereto collectively represent the entire understanding and
agreement between the parties with respect to the subject matter hereof.  This
Agreement supersedes all prior negotiations, letters of intent, or other
writings between the parties with respect to the subject matter hereof and
cannot be amended, supplemented, or modified except by waiver pursuant to
Section 12.6 or a written agreement which makes specific reference to this
Agreement and which is signed by the party against which enforcement of any such
amendment, supplement, or modification is sought.

     12.6 Waiver of Compliance; Consents.
          ------------------------------ 

     Any failure of either party to comply with any obligation, representation,
warranty, covenant, or agreement herein may be waived by the party entitled to
the benefits thereof only by a written instrument signed by the party granting
such waiver, but such waiver or failure to insist upon strict compliance with
such obligation, representation, warranty, covenant, or agreement shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.  Whenever this 

                                      -43-

initiate negotiations by providing written notice in letter form to the other
party setting forth in general terms the subject of the dispute. Representatives
of each party with full settlement authority shall meet at a mutually agreeable
time and place in order to attempt to resolve the dispute. If the dispute is not

Section 12.9(c) hereof, or, if they so agree, first proceed to mediation
pursuant to Section 12.9(b) hereof.

          (b) Mediation.  If a dispute arises out of or relates to this
              ---------                                                
Agreement or any alleged breach thereof and if the dispute is not settled
through negotiation as described in Section 12.9(a), Central and Insight may
agree to submit the dispute for mediation administered by the American
Arbitration Association (or any organization successor thereto) ("AAA") under
its Commercial Mediation Rules before resorting to arbitration. Either party may
initiate mediation pursuant to Rule 2 of the AAA's Commercial Mediation Rules.
The parties will cooperate with the AAA and with one another in the appointment
of a mediator and in scheduling the mediation proceedings. Unless otherwise
agreed by Central and Insight, the first mediation session shall be held no
later than thirty days after the date of filing the written request for
mediation, and the memorandum provided for under Rule 9 of the Commercial
Mediation Rules shall be provided to the mediator at least five days prior to
the first mediation session. All offers, promises, conduct, and statements,
whether oral or written, made in the course of the mediation by any of the
parties, their agents, employees, experts, and attorneys, and by the mediator or
any AAA employees, shall be confidential and inadmissible for any purposes,
including impeachment, in any arbitration or other

discoverable shall not be rendered inadmissible or non-discoverable as a result
of its use in the mediation. Either party may initiate arbitration with respect
to the matters submitted to mediation by filing a written demand for arbitration
with the AAA no sooner than thirty days after the first mediation session. The
mediation may continue after the commencement of arbitration if the parties so
agree. Unless otherwise agreed by Central and Insight, the mediator shall be
disqualified from serving as arbitrator in the case.

          (c) Arbitration.  If a dispute arises out of or relates to this

enforcement of, and proceedings pursuant to the arbitration clause in this
Agreement.  After arbitration has commenced pursuant to Rule 6 of the Commercial

seeking injunctive relief to maintain the status quo until such time as the
arbitration award is rendered or the dispute is otherwise resolved.

          (e) Request for Arbitration.  The party requesting arbitration shall

and by filing the notice with the AAA in accordance with Rule 6 of the
Commercial Arbitration Rules.  Within thirty days after the Arbitration Notice
is filed, Central and Insight shall select an arbitrator using the procedures
for arbitrator selection of the AAA from the arbitrators in the Large, Complex
case pool for the New York, New York, AAA office.

          (f) Administrative Conference and Hearing.  Upon selection of the

arbitrator, Central and Insight shall conduct an initial administrative
conference provided for by the Supplementary Procedures for Large, Complex
Disputes of the AAA at which Central and Insight shall agree to a schedule and
procedures for the exchange of relevant information and the hearing and to any
other matters the arbitrator or Central and Insight deem appropriate. Either
party may submit to the arbitrator prior to the hearing any written information
and may make any oral presentation at the hearing that it deems appropriate to
support its position with respect to the disputed matter.  At any hearing before
the arbitrator at which witnesses present testimony either in person or
telephonically Central and Insight shall be entitled to cross examine the
witnesses.

decision and award, including a statement of reasons upon which such award is
based, within thirty days after the arbitration hearing.  Except insofar as the

          -------------------------------                           
shareholders for the election of directors, for the consideration of reports to

may properly come before such meeting, shall be held on the second Tuesday in
April in each year or on such other date as may be fixed from time to time by

          Section 1.02.   Calling of  Meetings. Meetings of the shareholders may

exercise the authority of the president; the secretary; the directors by action
at a meeting, or a majority of the directors acting without a meeting; or the
holders of at least twenty-five percent (25%) of all shares outstanding and
entitled to vote thereat.

          Section  1.03.   Place of  Meetings. All meetings of shareholders
          -----------------------------------

<PAGE>
 
          Section 1.04.  Notice of Meetings.
          --------------------------------- 

              (A) Written notice stating the time, place and purposes of a
meeting of the shareholders shall be given either by personal delivery or by
mail not less than seven nor more than ten days before the date of the meeting,
(1) to each shareholder of record entitled to notice of the meeting, (2) by or
at the direction of the president or the secretary. If mailed, such notice shall
be addressed to the shareholder at his address as it appears on the records of
the corporation. Notice of adjournment of a meeting need not be given if the
time and place to which it is adjourned are fixed and announced at such meeting.
In the event of a transfer of shares after the record date for determining the
shareholders who are entitled to receive notice of a meeting of shareholders, it
shall not be necessary to give notice to the transferee. Nothing herein
contained shall prevent the setting of a record date in the manner provided by
law, the Articles or the Regulations for the determination of shareholders who
are entitled to receive notice of or to vote at any meeting of shareholders or
for any purpose required or permitted by law.

              (B) Following receipt by the president or the secretary of a
request in writing, specifying the purpose or purposes for which the persons
properly making such request have called a meeting of the shareholders,
delivered either in person or by registered mail to such officer by any persons
entitled to call a meeting of shareholders, such officer shall cause to be given
to the shareholders entitled thereto notice of a meeting to be held on a date
not less than seven nor more than sixty days


                                      -2-
<PAGE>
 
after the receipt of such request, as such officer may fix. If such notice is
not given within fifteen days after the receipt of such request by the president
or the secretary, then, and only then, the persons properly calling the meeting
may fix the time of meeting and give notice thereof in accordance with the
provisions of the Regulations.

          Section  1.05  Waiver of Notice. Notice of the time, place and purpose
          -------------------------------
or purposes of any meeting of shareholders may be waived in writing, either
before or after the holding of such meeting, by any shareholders, which writing
shall be filed with or entered upon the records of such meeting. The attendance
of any shareholder, in person or by proxy, at any such meeting without
protesting the lack of proper notice, prior to or at the commencement of the
meeting, shall be deemed to be a waiver by such shareholder of notice of such
meeting.

          Section 1.06.  Quorum. At any meeting of shareholders, the holders of
          ---------------------                                                
a majority of the voting shares of the corporation then outstanding and entitled
to vote thereat, present in person or by proxy, shall constitute a quorum for
such meeting. The holders of a majority of the voting shares represented at a
meeting, whether or not a quorum is present, or the chairman of the board, the
president, or the officer of the corporation acting as chairman of the meeting,
may adjourn such meeting from time to time, and if a quorum is present at such
adjourned meeting any business may be transacted as if the meeting had been held
as originally called.

          Section 1.07. Votes Required. At all elections of directors the
          -----------------------------
candidates receiving the greatest number of votes shall be elected. Any other
matter submitted to the shareholders for their vote shall be decided by the vote
of such proportion of the shares, or of any class of shares, or of each class,
as is required by law, the Articles or the Regulations.

          Section 1.08.  Order of Business. The order of business at any
          --------------------------------
meeting of shareholders shall be determined by the officer of the corporation
acting as chairman of such meeting unless otherwise determined by a vote of the
holders of a majority of the voting shares of the corporation then outstanding,
present in person or by proxy, and entitled to vote at such meeting.

          Section 1.09. Shareholders Entitled  to Vote.  Each shareholder of
          ----------------------------------------------
record on the books of the corporation on the record date for determining the
shareholders who are entitled to vote at a meeting of shareholders shall be
entitled at such meeting to one vote for each share of the corporation standing
in his name on the books of the corporation on such record date. The directors
may fix a record date for the determination of the shareholders who are entitled
to receive notice of and to vote at a meeting of shareholders, which record date
shall not be a date earlier than the date on which the record date is fixed and
which record date may be a maximum of sixty days preceding the date of the
meeting of shareholders.

          Section 1.10.  Cumulative Voting. If notice in writing shall be given
          --------------------------------                                     
by a shareholder to the president, a vice presi

                                      -4-
<PAGE>
 
dent or the secretary of the corporation, not less than forty-eight hours before
the time fixed for holding a meeting of the shareholders for the purpose of
electing directors if notice of such meeting shall have been given at least ten
days prior thereto, and otherwise not less than twenty-four hours before such
time, that such shareholder desires that the voting at such election shall be
cumulative, and if an announcement of the giving of such notice is made upon the
convening of the meeting by the chairman or secretary or by or on behalf of the
shareholder giving such notice, each shareholder shall have the right to
cumulate such voting power as he possesses and to give one candidate as many
votes as is determined by multiplying the number of directors to be elected by
the number of votes to which such shareholder is entitled, or to distribute such
number of votes on the same principle among two or more candidates, as he sees
fit.

          Section 1.11.  Proxies. At meetings of the shareholders any
          ----------------------                    
shareholder of record entitled to vote thereat may be represented and may vote
by a proxy or proxies appointed by an instrument in writing signed by such
shareholder, but such instrument shall be filed with the secretary of the
meeting before the person holding such proxy shall be allowed to vote
thereunder. No proxy shall be valid after the expiration of eleven months after
the date of its execution, unless the shareholder executing it shall have
specified therein the length of time it is to continue in force.

          Section 1.12.  Inspectors of Election. In advance of any meeting of
          -------------------------------------
shareholders, the directors may appoint inspectors

                                      -5-
<PAGE>
 
of election to act at such meeting or any adjournment thereof; if inspectors are
not so appointed, the officer of the corporation acting as chairman of any such
meeting may make such appointment. In case any person appointed as inspector
fails to appear or act, the vacancy may be filled only by appointment made by
the directors in advance of such meeting or, if not so filled, at the meeting by
the officer of the corporation acting as chairman of such meeting. No other
person or persons may appoint or require the appointment of inspectors of
election.

                                  ARTICLE TWO

                                   DIRECTORS

          Section  2.01. Authority  and Qualifications.  Except where the law,
          --------------------------------------------
the Articles or the Regulations otherwise provide, all authority of the
corporation shall be vested in and exercised by its directors. Directors need
not be shareholders of the corporation.

          Section 2.02.  Number of Directors and Term of Office.
          ----------------------------------------------------- 

              (A) The number of directors of the corporation shall be one (1) so
long as all shares of the corporation are owned of record by one shareholder;
and at any time when all shares of the corporation are owned of record by two or
more shareholders, the number of directors of the corporation shall be three
(3). Each director shall be elected to serve until the next annual meeting of
shareholders and until his successor is duly elected and qualified or until his
earlier resignation, removal from office, or death.

                                     -6-
<PAGE>
 
              (B) The number of directors may be fixed or changed at a meeting
of the shareholders called for the purpose of electing directors at which a
quorum is present, only by the affirmative vote of the holders of not less than
a majority of the voting shares which are represented at the meeting, in person
or by proxy, and entitled to vote on such proposal.

              (C) The directors may fix or change the number of directors and
may fill any director's office that is created by an increase in the number of
directors; provided, however, that the directors may not increase the number of
directors to more than three (3).

              (D) No reduction in the number of directors shall of itself have
the effect of shortening the term of any incumbent director.

          Section  2.03. Election. At each annual meeting of shareholders for
          -----------------------
the election of directors, the successors to the directors whose term shall
expire in that year shall be elected, but if the annual meeting is not held or
if one or more of such directors are not elected thereat, they may be elected at
a special meeting called for that purpose. The election of directors shall be by
ballot whenever requested by the presiding officer of the meeting or by the
holders of a majority of the voting shares outstanding, entitled to vote at such
meeting and present in person or by proxy, but unless such request is made, the
election shall be viva voce.

          Section 2.04.  Removal. A director or directors may be removed from
          ----------------------                                             
office, with or without assigning any cause, only by

                                      -7-
<PAGE>
 
the vote of the holders of shares entitling them to exercise not less than a
majority of the voting power of the corporation to elect directors in place of
those to be removed, provided that unless all the directors, or all the
directors of a particular class (if the directors of the corporation are divided
into classes), are removed, no individual director shall be removed in case the
votes of a sufficient number of shares are cast against his removal which, if
cumulatively voted at an election of all directors, or all the directors of a
particular class, as the case may be, would be sufficient to elect at least one
director. In case of any such removal, a new director may be elected at the same
meeting for the unexpired term of each director removed. Failure to elect a
director to fill the unexpired term of any director removed shall be deemed to
create a vacancy in the board.

          Section  2.05. Vacancies. The remaining directors, through less than
          ------------------------
a majority of the whole authorized number of directors, may, by the vote of a
majority of their number, fill any vacancy in the board for the unexpired term.
A vacancy in the board exists within the meaning of this Section 2.05 in case
the shareholders increase the authorized number of directors but fail at the
meeting at which such increase is authorized, or an adjournment thereof, to
elect the additional directors provided for, or in case the shareholders fail at
any time to elect the whole authorized number of directors.

          Section 2.06.  Meetings. A meeting of the directors shall be held
          ----------------------- 
immediately following the adjournment of each

                                      -8-
<PAGE>
 
annual meeting of shareholders at which directors are elected, and notice of
such meeting need not be given. The directors shall hold such other meetings as
may from time to time be called, and such other meetings of directors may be
called only by the chairman of the board, the president, or any two directors.
All meetings of directors shall be held at the principal office of the
corporation in Columbus, Ohio or at such other place within or without the State
of Ohio, as the directors may from time to time determine by a resolution.
Meetings of the directors may be held through any communications equipment if
all persons participating can hear each other and participation in a meeting
pursuant to this provision shall constitute presence at such meeting.

          Section 2.07.  Notice  of Meetings. Notice of the time and place of
          ----------------------------------                                 
each meeting of directors for which such notice is required by law, the
Articles, the Regulations or the By-Laws shall be given to each of the
directors by at least one of the following methods:

              (A)   In a writing mailed not less than three days before such
                    meeting and addressed to the residence or usual place of
                    business of a director, as such address appears on the
                    records of the corporation; or

              (B)   By telegraph, cable, radio, wireless, or a writing sent or
                    delivered to the residence or usual place of business of a
                    director as the same appears on the records of the corpora-


                                      -9-
<PAGE>
 
                    tion, not later than the day before the date on which such
                    meeting is to be held; or

              (C)   Personally or by telephone not later than the day before the
                    date on which such meeting is to be held.

Notice given to a director by any one of the methods specified in the
Regulations shall be sufficient, and the method of giving notice to all
directors need not be uniform. Notice of any meeting of directors may be given
only by the chairman of the board, the president or the secretary of the
corporation. Any such notice need not specify the purpose or purposes of the
meeting. Notice of adjournment of a meeting of directors need not be given if
the time and place to which it is adjourned are fixed and announced at such
meeting.

          Section 2.08.  Waiver of Notice. Notice of any meeting of directors
          -------------------------------                                    
may be waived in writing, either before or after the holding of such meeting, by
any director, which writing shall be filed with or entered upon the records of
the meeting. The attendance of any director at any meeting of directors without
protesting, prior to or at the commencement of the meeting, the lack of proper

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 (including, without limitation, any action
threatened or instituted by or in the right of the corporation), by reason of

corporation, or is or was serving at the request of the corporation as a
director, trustee, officer, employee or agent of another corporation (domestic
or foreign, nonprofit or for profit), partnership, joint venture, trust or other
enterprise, against expenses (including, without limitation, attorneys' fees,
filing fees, court reporters' fees and transcript costs), judgments, fines and

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 matter, to have
had no reasonable cause to believe his conduct was unlawful, and the termination
of any action, suit or proceeding by judgment, order, settlement or conviction,

corporation, or is or was serving at the request of the corporation as a
director, trustee, officer, employee or agent of another corporation (domestic
or foreign, nonprofit or for profit), partnership, joint venture, trust or other
enterprise, in respect of any claim, issue or matter asserted in such action or
suit as to which he shall have been adjudged to be liable for gross negligence
or misconduct (other than negligence) in the performance of his duty to the
corporation unless and only to the extent that the Court of Common Pleas of
Franklin County, Ohio or the court in which such action or suit was brought
shall determine upon application that, despite such adjudication of liability,
and in view of all the circumstances of the case, he is fairly and reasonably
entitled to such indemnity as such Court of Common Pleas or such other court
shall deem proper; and

withstanding, to the extent that an officer or director of the corporation has
been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Section 5.01, or in defense of any claim, issue or
matter therein, he shall be promptly indemnified by the corporation against
expenses (including, without limitation, attorneys' fees, filing fees, court

under Section 5.01 and not precluded under Section 5.02 shall be made by the
corporation only upon a determination that such indemnification of the officer
or director is proper in the circumstances because he has met the applicable
standard of conduct set forth in Section 5.01. Such determination may be made
only (A) by a majority vote of a quorum consisting of directors of the
corporation who were not and are not parties to, or threatened with, any such
action, suit or proceeding, or (B) if such a quorum is not obtainable or if a
majority of a quorum of disinterested directors so directs, in a written opinion
by independent legal counsel other than an attorney, or a firm having associated

for any reason to make any such determination, and no decision for any reason to
deny any such determination, by the disinterested directors under division (A)
or by independent legal counsel under division (B) or by shareholders under
division (C) of this Section 5.04 shall be evidence in rebuttal of the
presumption recited in Section 5.01. Any determination made by the disinterested
directors under division (A) or by independent legal counsel under division (B)
of this Section 5.04 to make indemnification in respect of any claim, issue or
matter asserted in an action or suit threatened or brought by or in the right of
the corporation shall be promptly communicated to the person who threatened or
brought such action or suit, and within ten (10) days after receipt of such
notification such person shall have the right to petition the Court of Common
Pleas of Franklin County, Ohio or the court in which such action or suit was
brought, if any, to review the reasonableness of such determination.

or proceeding to or on behalf of the officer or director promptly as such
expenses are incurred by him, but only if such officer or director shall first
agree, in writing, to repay all amounts so paid in respect of any claim, issue
or other matter asserted in such action, suit or proceeding in defense of which
he shall not have been successful on the merits or otherwise:

          (A) Unless it shall ultimately be determined as provided in Section
5.04 that he is entitled to be indemnified by the corporation as provided under
Section 5.01; or

          (B) If, in respect of any claim, issue or other matter asserted by or
in the right of the corporation in such action or suit, he shall have been
adjuged to be liable for gross negligence or misconduct (other than negligence)
in the performance of his duty to the corporation, unless and only to the extent
that the Court of Common Pleas of Franklin County, Ohio or the court in which
such action or suit was brought shall determine upon application that, despite
such adjudication of liability, and in view of all the circumstances, he is
fairly and reasonably entitled to all or part of such indemnification.

     Section 5.06.   Article Five Not Exclusive. The indemnification provided
     ------------------------------------------

                                 ARTICLE XIII

                     Voluntary Dissolution and Termination
                     -------------------------------------

     The PARTNERSHIP may be dissolved and terminated only upon approval of all
the partners. In the event of such election to dissolve and terminate, all
partners shall be given notice thereof and the partners (or a liquidating
partner selected and authorized by them) shall proceed with reasonable
promptness to wind up the business of the PARTNERSHIP. The method of winding up
the business of the PARTNERSHIP shall be either to sell the assets of the
PARTNERSHIP, in whole or in part, or to distribute the assets in kind. The
method of winding up the business of the PARTNERSHIP and the terms of such sale
or distribution shall be only as determined by all the partners. The assets of
the PARTNERSHIP, or the money or other property resulting from the sale of such
assets, shall be distributed in the following

                                      -4-
<PAGE>
 
order: (1) to the creditors of the PARTNERSHIP, including any partner who is a
creditor of the PARTNERSHIP; (2) to the partners, in respect of their capital
contribution; (3) to the partners in respect of their share of any undistributed
profits in their income accounts; and (4) to the partners in accordance with
their percentages of profit and loss for the fiscal year in which such
distribution occurs in respect of any remaining funds.

                                  ARTICLE XIV

                                  Withdrawal
                                  ----------

     If any one or more but less than all of the partners desire to terminate or
withdraw from the PARTNERSHIP, they shall give notice of such desire to the 
remaining partners.  The partner or partners giving such notice are hereinafter 
referred to as the "withdrawing partner".  The withdrawing partner shall deliver
to the non-withdrawing partner or partners an offer (herein called the "Offer") 
in writing stating the price at which the withdrawing partner is willing to 
purchase all of the assets of the PARTNERSHIP and the terms and conditions upon 
which such price shall be payable.  The non-withdrawing partners shall within 
sixty (60) days after receipt of such Offer elect to either: (1) purchase the 
interest of the withdrawing partner at a price computed by multiplying the price
set forth in the Offer by the percentage of interest in the PARTNERSHIP of the 
withdrawing partner (any down-payments and deferred payments provided for in the
Offer shall be reduced in the same proportion as the reduction of the purchase
price provided for in the preceding sentence, but otherwise the purchase price
shall be on the same terms and conditions as contained in the Offer); or (2) the
PARTNERSHIP shall sell to the withdrawing partner and the withdrawing partner
shall purchase all of the assets of the PARTNERSHIP at a price and on the terms
and conditions set forth in the Offer; or (3) if less than all of the non-
withdrawing partners elect to purchase the interest of the withdrawing partner
pursuant to subparagraph (1) above, then the non-withdrawing partners who do not
elect to purchase shall be deemed to be withdrawing partners and the offer to
sell made by the first withdrawing partner shall be deemed to have been adopted
by said non-withdrawal


                                      -5-

<PAGE>
 
partners who have not elected to purchase. If a non-withdrawing partner fails to
give the withdrawing partner notice of its election within the time hereinabove
provided for, it shall be conclusively presumed that the non-withdrawing partner
who has failed to give such notice has elected to sell to the withdrawing
partner pursuant to subparagraph (2) above. The closing of the purchase shall be
held in a mutually convenient place in Sarasota County, Florida, at a time
agreed upon by the partners, but not more than one hundred twenty (120) days
after the receipt of the Offer by the non-withdrawing partner. The PARTNERSHIP
of the partners, as the case may be, shall convey the property or their interest
in the PARTNERSHIP by appropriate instruments to the purchasing party free and
clear of all encumbrances save those to which the purchasing party has agreed
shall continue. The purchase or sale of the assets of the PARTNERSHIP or
PARTNERSHIP interest pursuant to this paragraph shall not terminate the
PARTNERSHIP and the partner or partners acquiring said assets or interest may
continue the PARTNERSHIP or wind up its business. If either the withdrawing
partner or non-withdrawing partner pursuant to the election provided above are
to purchase the assets or interest of the other but thereafter such partner
fails to close such purchase, then the non-defaulting partner may continue the
PARTNERSHIP and/or purchase the interest in the PARTNERSHIP of the defaulting
partner at the price set forth in the Offer multiplied by the percentage of
interest in the PARTNERSHIP of the defaulting partner in the manner and in
accordance with the time schedule set forth above.

                                  ARTICLE XV

                        Death, Bankruptcy, Incompetency
                        -------------------------------

        The death, bankruptcy or incompetency of a general partner shall not 
terminate the PARTNERSHIP and shall have no effect upon the continuing of the 
business of the PARTNERSHIP.  In the event of death or incompetency of a partner
having less than a majority in interest in the PARTNERSHIP, then the guardian 
or personal representative, as the case may be, of such partner shall become a 
partner in the PARTNERSHIP with the same interest


                                     - 6 -
<PAGE>
 
in the profits, losses and capital of the PARTNERSHIP as possessed by the 
deceased or incompetent partner at the time of death or incompetency and with
the same rights and privileges as though originally named as a partner herein.
In the event of the death, bankruptcy or incompetency of a partner having a
majority in interest in the PARTNERSHIP, then the interest of such partner shall
immediately be transferred to Dennis J. McGillicuddy to be held by him in trust
for said partner in the case of incompetency or bankruptcy of said partner or
for the party who was to receive said interest in the event of the death of said
partner. During the period that said interest is so held in trust, the affairs
of the PARTNERSHIP shall continue to be conducted in accordance with the terms
of this PARTNERSHIP, and the authority and control attendant with the majority
in interest shall be exercised by Dennis J. McGillicuddy. The conflict arising
by virtue of Dennis J. McGillicuddy holding partnership interests both for
himself and in trust is hereby acknowledged by the partners, and such conflict
shall not be grounds for disqualification of Dennis J. McGillicuddy, who shall
be subject to removal only upon proof of actual breach of his fiduciary duties.
As trustee, Dennis J. McGillicuddy shall use his best efforts to liquidate the
interest held in trust upon such terms as are fair, reasonable and proper under
the circumstances within five (5) years from the date that such interest
commenced to be so held in trust. In the event that Dennis J. McGillicuddy is
unwilling or unable to hold such interest in trust, such interest shall be
transferred in trust to such party as shall be determined by the majority of
Dennis J. McGillicuddy, Martin Thaler and Michael McGillicuddy, or by a majority
of such of them as shall then be living. The party holding said interest in
trust shall have the same powers and duties as granted herein to Dennis J.
McGillicuddy and the party holding said interest in trust, including Dennis J.
McGillicuddy, may receive compensation for services rendered to the PARTNERSHIP
or for services rendered in behalf of the interest held in trust.

                                  ARTICLE XVI

                               Power of Attorney

severally, hereby irrevocably constitute and appoint those general partners that
have the authority to bind the PARTNERSHIP (in accordance with ARTICLE VII 
hereof), with full power of substitution, their true and lawful 
attorney-in-fact, in their name, place and stead, to make, execute, sign, 
acknowledge, record and file on behalf of each of them and on behalf of the 
PARTNERSHIP and and all instruments as may be deemed desirable by such general 
partners authorized to bind the PARTNERSHIP (in accordance with ARTICLE VII 
hereof) to carry out fully and completely the provisions of this AGREEMENT. The 
grant of authority set forth above: (1) is a Special Power of Attorney coupled 
with an interest; (2) is irrevocable and shall survive the death, bankruptcy, 
incompetency or withdrawal of the general partner granting the power; (3) may be
exercised by any of the general partners who form part of the majority of the 
general partners authorized to bind the PARTNERSHIP (in accordance with ARTICLE 
VII hereof) by using a facsimile signature or by listing all of the general 
partners executing any instrument with a single signature as attorney-in-fact 
for all of them; and (4) shall survive any transfer of a partner's interest in 
the PARTNERSHIP (whether by operation of law or otherwise).

                                 ARTICLE XVII

                           Liability of the Partners

     The partners shall not be liable, responsible or accountable, in damages or
otherwise to the PARTNERSHIP or any partner for any act, or failure to act, on 
behalf of the PARTNERSHIP that is within the scope of the authority conferred on
such general partners by this Agreement or by the Uniform Partnership Act of 
Florida or otherwise, unless such act or omission was performed or omitted 
fraudulently or in bad faith or constituted wanton and willful misconduct or 
gross negligence.

                                 ARTICLE XVIII

                                Indemnification

     The PARTNERSHIP shall indemnify and hold harmless any and all partners and 
their agents from and against any loss, expense, damage or injury suffered or 
sustained by him by reason of any

                                      -8-
<PAGE>
 
act, omission or alleged act or omission arising out of his activities on 
behalf of the PARTNERSHIP or in furtherance of the interests of the PARTNERSHIP 
including, but not limited to, any judgement, award, settlement, reasonable 
attorneys' fees, and other costs or expenses incurred in connection with the 
defense of any actual or threatened action, proceeding, or claim and including 
any payments made by any or all of the general partners to any of his attorneys 
or agents; provided that the act or omission upon which such actual or 
threatened action, proceeding or claim is based is not judicially determined to 
have been performed or omitted fraudulently or in bad faith or as a result of 
wanton and willful misconduct or gross negligence by any or all of the general 
partners or their agents.

                                  ARTICLE XIX

which Central's obligation is canceled pursuant to Section 2.1(d)(4)(B) of the
Contribution Agreement and the denominator of which is $13,333,333;

                  (iii) in consideration for any Capital Contribution made by
any Person pursuant to Section 2.1(d)(4)(A)(2) of the Contribution Agreement,
there shall be assigned to the Common Interest of such Person, effective as of
the date of this Agreement, a number of Units equal to the product of 100,000
times a fraction, the numerator of which is the amount of all Capital
Contribution made by such Person pursuant to Section 2.1(d)(4)(A)(2) of the
Contribution Agreement and the denominator of which is $13,333,333; and

                  (iv) there shall be assigned to any other Common Interest
issued pursuant to Section 7.5, including any additional Common Interest issued
to Insight or Central, the number of Units required to be assigned to such
Common Interest under the terms of its issuance.

         "Voting Interests" means the Preferred A Interest and the Preferred B
Interest, collectively, except that, at such time as (1) the Preferred A
Interest and the Preferred B Interest both cease to be outstanding, or (2) a
Person other than Central owns a majority of the Preferred A Interest and the
Preferred B Interest (determined in the manner described in the following
sentence), or (3) none of the Principals owns, directly or indirectly, any
interest in Central, or (4) Central ceases to be controlled, directly or
indirectly, by Insight or any Affiliate of Insight, then "Voting Interests"
shall mean the Common Interests. A "majority" of the outstanding Voting
Interests means, if the Voting Interests consist of the Preferred A Interest and
the Preferred B Interest, any portion of the Preferred A Interest and the
Preferred B Interest that together represents a majority of the sum of the
Preferred A Capital Amount and the Preferred B Capital Amount that is
represented by the total outstanding Preferred A Interest and Preferred B
Interest, and, if the Voting Interests consist of the Common Interests, any
portion of the Common Interests to which has been assigned a majority of the
Units assigned to all the outstanding Common Interests.

than a partnership for federal income tax purposes without the affirmative
unanimous consent of the Members and the prior written consent of the

Person from taking any action that would cause any Affiliate of Insight (other
than the Company and any Person more than half of the assets of which consist of
direct or indirect equity interests in the Company at the time such action is
taken) to be characterized as a corporation for federal income tax purposes. A
determination of whether any action would cause the Company to be characterized
as an entity other than a partnership for federal income tax purposes will be
based upon a declaratory judgment or similar relief obtained from a court of
competent jurisdiction, a favorable ruling from the Internal Revenue Service, or
the receipt of an opinion of counsel reasonably satisfactory to the Members.

                  (a)      Interim Refinancing.

                           (i)      Insight may obtain and submit to Central 
and the Principals at any time and from time to time a proposal from a financial
institution of nationally recognized standing for the refinancing of the Senior
Debt or the Subordinated Debt. In addition, if (A) any portion of the Senior
Debt or the Subordinated Debt becomes due and payable before its stated
maturity, or (B) the Company fails to make any distributions required by Section
4.1(a)(i), Section 4.1(a)(ii), or Section 4.1(a)(iii) on or before the
applicable Guaranteed Payment Date, Preferred A Distribution Date, or Preferred
B Distribution Date, or (C) Insight determines that the Company is likely to be
unable to make all distributions required by Section 4.1(a)(i), Section
4.1(a)(ii), and Section 4.1(a)(iii) at the next applicable Guaranteed Payment
Date, Preferred A Distribution Date, or Preferred B Distribution Date, Insight
shall use commercially reasonable efforts to obtain and submit to Central and
the Principals either (as elected by Insight in good faith) a proposal from a
financial institution of nationally recognized standing for the refinancing of
the Senior Debt and the Subordinated Debt or a proposal from the holders of the
Senior Debt and the Subordinated Debt to modify the terms thereof in response to
the condition described in this sentence.

                                      -17-
<PAGE>
 
                           (ii)     After obtaining any proposal pursuant to 
Section 3.5(a)(i), Insight may require that the Borrowers refinance or modify
the Senior Debt or the Subordinated Debt in accordance with the terms of such
proposal, and the parties agree that the Borrowers will comply with such
requirement, so long as the terms of the Senior Debt and the Subordinated Debt
as it would exist after the consummation of such refinancing or modification (A)
would not require any Person or its assets (including assets that may be
acquired after such refinancing or modification) to be liable or otherwise
responsible for the payment or collection of such Senior Debt or Subordinated
Debt, or for the performance of the obligations of any other Person, to a
greater extent than such Person or its assets is liable or otherwise responsible
under the Senior Debt and the Subordinated Debt as it exists prior to the
consummation of such refinancing or modification, (B) would not impose any
covenants on any Person other than a Borrower that are not imposed on such
Person under the Senior Debt and the Subordinated Debt as it will exist at the
Closing, and (C) would not otherwise modify the structure of the Senior Debt or
the Subordinated Debt in a manner that is adverse to the Principals.

                           (iii)    If Insight is unable to obtain a proposal
pursuant to Section 3.5(a)(i) to refinance or modify the Senior Debt or the
Subordinated Debt on terms that conform with the criteria described in Section
3.5(a)(ii), and the second sentence of Section 3.5(a)(i) does not apply, then
the Principals may elect, in their sole discretion, whether the Borrowers will
consummate the refinancing or modification of the Senior Debt and the
Subordinated Debt on the terms of any proposal obtained by Insight and submitted
to Central and the Principals.

                           (iv)     If Insight is unable to obtain a proposal
pursuant to Section 3.5(a)(i) to refinance or modify the Senior Debt or the
Subordinated Debt on terms that conform with the criteria described in Section
3.5(a)(ii) and the second sentence of Section 3.5(a)(i) applies, then the
Principals shall elect either (A) that the Borrowers will consummate the
refinancing or modification of the Senior Debt and the Subordinated Debt on the
terms of the proposal, if any, submitted to Central and the Principals, or (B)
that the Principals shall sell to Insight or a Person designated by Insight, and
Insight or a Person designated by Insight shall purchase from the Principals,
for one dollar (plus the Tax Amount that would be distributable to Central on
the date of the next scheduled April Distribution, calculated as if the
Company's Fiscal Year ended on the closing of such purchase), all of the
outstanding membership interests in the Shareholders; provided, however, that
(A) the Principals may not elect to require that Insight or a Person designated
by Insight purchase all of the outstanding membership interests in the
Shareholders, and the Principals shall be deemed to have elected that the
Borrowers will consummate the proposed refinancing or modification, if the
conditions specified in Section 3.5(f)(vi) are not satisfied at the time that
the Principals make such election, and (B) the Principals shall be deemed to
have elected that the Borrowers will consummate the proposed refinancing or
modification if the Principals fail to notify Insight of their election within
twenty-one days after the delivery to the Principals and their legal counsel of
the proposal obtained by Insight pursuant to Section 3.5(a)(i) and any other
information concerning the proposed refinancing or modification that the
Principals shall have reasonably requested within ten days after their receipt
of such proposal. If the Principals elect to require that Insight or a Person
designated by Insight purchase all of the outstanding membership interests in
the Shareholders, the closing of such purchase shall occur immediately prior to
the earlier of (A) the acceleration of the Senior Debt or the Subordinated
Debt as it then exists (if acceleration of the Senior Debt or the Subordinated

                                      -18-

Debt shall not have already occurred) or (B) the consummation of the proposed
refinancing or modification of the Senior Debt or the Subordinated Debt, and,
upon such closing, Insight agrees that it or its designee will accept all of the
outstanding membership interests in the Shareholders, provided that neither
Insight nor its designee shall thereby acquire any personal liability for either
the Senior Debt or the Subordinated Debt.

                           (v)      If either the Senior Debt or the 
Subordinated Debt is accelerated, then, regardless whether Insight had the
opportunity to obtain a proposal pursuant to Section 3.5(a)(i) to refinance or
modify the Senior Debt or the Subordinated Debt, the Principals may elect to
sell to Insight or a Person designated by Insight, and Insight or a Person
designated by Insight shall purchase from the Principals, for one dollar (plus
the Tax Amount that would be distributable to Central on the date of the next
scheduled April Distribution, calculated as if the Company's Fiscal Year ended
on the closing of such purchase), all of the outstanding membership interests in
the Shareholders; provided, however, that the Principals may not elect to
require that Insight or a Person designated by Insight purchase all of the
outstanding membership interests in the Shareholders if the conditions specified
in Section 3.5(f)(vi) are not satisfied at the time that the Principals would
otherwise be permitted to make such election. If the Principals elect to require
that Insight or a Person designated by Insight purchase all of the outstanding
membership interests in the Shareholders, the closing of such purchase shall
occur as soon as practicable following such election and, in any event, prior to
any redemption of the Preferred A Interest or the Preferred B Interest. Upon
such closing, Insight agrees that it or its designee will accept all of the
outstanding membership interests in the Shareholders, provided that neither
Insight nor its designee shall thereby acquire any personal liability for either
the Senior Debt or the Subordinated Debt.

                  (b)      Refinancing at Maturity of Senior Debt.

                           (i)      Prior to the maturity of the Senior Debt,
Insight shall use commercially reasonable efforts to obtain and submit to
Central and the Principals a proposal from a financial institution of nationally
recognized standing for the refinancing of the Senior Debt at or prior to its
maturity. Insight shall use commercially reasonable efforts to obtain such
proposal sufficiently in advance of the maturity of the Senior Debt so as to
permit the refinancing of the Senior Debt to be consummated at or prior to the
maturity of the Senior Debt in a manner consistent with the rights and
obligations of the parties under this Section 3.5.

                           (ii) If Insight is able to obtain a proposal pursuant
to Section 3.5(b)(i) to refinance the Senior Debt that (A) would not require any
Person or its assets (including assets that may be acquired after such
refinancing) to be liable or otherwise responsible for the payment or collection
of such Senior Debt, or for the performance of the obligations of any other
Person, to a greater extent than such Person or its assets is liable or
otherwise responsible under the Senior Debt as it exists prior to the
consummation of such refinancing, (B) would not impose any covenants on any
Person other than a Borrower that are not imposed on such Person under the
Senior Debt as it will exist at the Closing, and (C) would not otherwise modify
the structure of the Senior Debt or the Subordinated Debt in a manner that is
adverse to the Principals, then (1) the parties agree that the Borrowers will
consummate the refinancing of the Senior Debt on the terms of such proposal and
(2) Insight agrees that, if the refinancing contemplated by such proposal is not
consummated for any

                                      -19-

reason (other than inaction by a Principal to which Section 3.5(d) applies)
prior to the maturity of the Senior Debt as it exists prior to the consummation
of such refinancing, Insight or an Affiliate of Insight will itself refinance
the Senior Debt on the terms of such proposal (and such substitution of Insight
or its Affiliate as the lender shall not constitute action by Insight or its
Affiliate to modify the structure of the Senior Debt or the Subordinated Debt).

                           (iii) If Insight is unable to obtain a proposal to
refinance the Senior Debt on terms that conform with the criteria described in
Section 3.5(b)(ii), then the Principals shall elect either (A) that the
Borrowers will consummate the refinancing of the Senior Debt on the terms of the
proposal, if any, submitted to Central and the Principals or (B) that the
Principals shall sell to Insight or a Person designated by Insight, and Insight
or a Person designated by Insight shall purchase from the Principals, for one
dollar (plus the Tax Amount that would be distributable to Central on the date
of the next scheduled April Distribution, calculated as if the Company's Fiscal
Year ended on the closing of such purchase), all of the outstanding membership
interests in the Shareholders; provided, however, that (A) the Principals may
not elect to require that Insight or a Person designated by Insight purchase all
of the outstanding membership interests in the Shareholders, and the Principals
shall be deemed to have elected that the Borrowers will consummate the proposed
refinancing, if the conditions specified in Section 3.5(f)(vi) are not satisfied
at the time that the Principals make such election, and (B) the Principals shall
be deemed to have elected that the Borrowers will consummate the proposed
refinancing if the Principals fail to notify Insight of their election within
twenty-one days after the delivery to the Principals and their legal counsel of
the proposal obtained by Insight pursuant to Section 3.5(b)(i) and any other
information concerning the proposed refinancing that the Principals shall have
reasonably requested within ten days after their receipt of such proposal. If
the Principals elect to require that Insight or a Person designated by Insight
purchase all of the outstanding membership interests in the Shareholders, the
closing of such purchase shall occur immediately prior to the earlier of (A) the
maturity of the Senior Debt as it then exists or (B) the consummation of the
proposed refinancing of the Senior Debt, and, upon such closing, Insight agrees
that it or its designee will accept all of the outstanding membership interests
in the Shareholders, provided that neither Insight nor its designee shall
thereby acquire any personal liability for either the Senior Debt or the
Subordinated Debt.

                           (iv) Upon the refinancing of any Senior Debt pursuant
to this Section 3.5,

including any refinancing pursuant to this Section 3.5(b) (including any such
refinancing by Insight or an Affiliate of Insight), the obligations of Insight
under this Section 3.5(b) shall again apply upon the maturity of the Senior Debt
as it exists after the consummation of such refinancing.

                           (v) The obligations of Insight under this Section
3.5(b) shall terminate upon the earliest of (A) the death of the last to die of
Barry Silverstein, Dennis McGillicuddy, and D. Stevens McVoy, (B) the first date
on which none of the Principals owns, directly or indirectly, any interest in
any of the Borrowers, or (C) the receipt by the Principals of an opinion of
their legal counsel that, in its opinion, there are no circumstances under which
the refinancing, retirement, satisfaction, or purchase of the Senior Debt, in
any manner and on any terms, would increase by more than a de minimis amount the
likelihood of those adverse tax consequences to the Principals that were
intended to be avoided by the Senior Debt and the Subordinated Debt, as it will
exist at the Closing.

                  (c) Funding Purchase of Debt. The Company may make loans to
Insight or any Affiliate of Insight for the purpose of funding the acquisition
by such Person of any of the outstanding Senior Debt or Subordinated Debt. The
proceeds used to make such loans may include the proceeds of the issuance of
Membership Interests (subject to the restrictions on the issuance of Membership
Interests provided in Section 8.5(b)). The terms of any such loan shall:

                           (i)      provide that all obligations and 
liabilities of such Person with respect to such loan shall be secured by all of
such Person's interest in the Senior Debt or Subordinated Debt so purchased, and
any replacements or proceeds thereof (but such loan shall otherwise be non-
recourse to such Person);

                           (ii)     require the payment to the Company, either
as principal, interest, or additional interest, of all amounts received by such
Person with respect to the Senior Debt or Subordinated Debt so purchased; and

                           (iii) require that the Person to which the loan is
made, if other than Insight,

remain an Affiliate of Insight.

                  (d) Financing by the Company. If Insight obtains and submits
to Central and the Principals a proposal for the refinancing or modification of
the Senior Debt or Subordinated Debt pursuant to Section 3.5(a)(i) or Section
3.5(b)(i) and either (1) the terms of the proposed refinancing or modification
conform with the criteria described in Section 3.5(a)(ii) or Section 3.5(b)(ii),
as applicable, or (2) the Principals expressly agreed that the Borrowers will
consummate the refinancing or modification of the Senior Debt and the
Subordinated Debt on the terms of such proposal, and, thereafter, any of the
Principals fails to take any action reasonably necessary to consummate the
refinancing or modification of the Senior Debt and the Subordinated Debt on the
terms of such proposal (including executing and delivering any consent,
approval, or authority) and fails to cure such failure within ten Business Days
after its receipt of written notice from Insight specifying such failure and
specifying that Insight believes this Section 3.5(d) applies to such failure,
then Insight may cause the Company or any Subsidiary of the Company to incur
indebtedness directly, on terms approved by the Management Committee, and use
the proceeds of such indebtedness to purchase or repay the Senior Debt or the
Subordinated Debt.

                  (e) Other Actions Prohibited. Insight agrees that, except as
specifically permitted by this Section 3.5, neither Insight nor any of its
Affiliates (including the Company) will take any willful or intentional action
in any capacity (including as manager of the Shareholders) that is intended to
have, and has, the effect of modifying the structure of the Senior Debt or the
Subordinated Debt (such as by imposing any covenants on any Person other than a
Borrower that are not imposed on such Person under the Senior Debt or the
Subordinated Debt as it will exist at the Closing or agreeing that any Person or
its assets would be liable or otherwise responsible for the payment or
collection of the Senior Debt or the Subordinated Debt, or for the performance
of the obligations of any Borrower, to a greater extent than such Person or its
assets is liable or otherwise responsible under the Senior Debt and the
Subordinated Debt as then in effect). The Principals and Central agree that any
action taken by Insight in connection with its management of the business and

                                      -21-
<PAGE>
 
operations of the Company, Central, or the Shareholders (whether under this
Agreement or under any of the management agreements between the Shareholders and
Insight) that does not directly relate to the structure of the Senior Debt or
the Subordinated Debt shall not be considered an action that was intended to
have the effect of modifying the structure of the Senior Debt or the
Subordinated Debt unless Insight, in taking such action, intended that a
modification of such structure result from such action. Solely for purposes of
this Section 3.5(e), (1) a Person shall not be considered an Affiliate of
Insight with respect to any action taken by such Person if neither Insight
Parent nor any Person controlling Insight Parent possessed the power, directly
or indirectly, to cause such Person to refrain from taking such action, whether
through the ownership of voting securities, contractually, or otherwise, and (2)
"Insight Parent" means Insight Communications Company, L.P., or, if Insight
ceases to be controlled, directly or indirectly, by one or more individuals who,
on the date of this Agreement, collectively control Insight, the ultimate parent
entity (as determined in accordance with the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, and the rules and regulations promulgated
thereunder) of Insight.

                  (f)      Other General Provisions.

                           (i)      The manner of soliciting and obtaining any
refinancing proposal pursuant to this Section 3.5 shall be determined by
Insight. The Principals will cooperate, as reasonably requested by Insight, in
connection with Insight's efforts to solicit and obtain any refinancing proposal
pursuant to this Section 3.5.

                           (ii)     In connection with any refinancing 
pursuant to this Section 3.5, the Company shall pay all costs and expenses
incurred by any of the Borrowers, any of the Principals, or any of their
respective Affiliates in connection with the consummation of such refinancing,
including the authorization, preparation, execution, and performance of any
agreements or other instruments relating thereto, to the extent such costs and
expenses are similar in kind to the costs and expenses that the Company would
have incurred in issuing indebtedness similar to the Senior Debt or the
Subordinated Debt.

                           (iii) In connection with any refinancing or purchase
of any of the Senior Debt or the Subordinated Debt pursuant to this Section 3.5,
Insight and the Principals shall agree to appropriate modifications to the terms
of the Preferred A Interest and the Preferred B Interest, to the extent
necessary to preserve the reasonable expectations of Insight and the Principals
under this Agreement. Any agreement between Insight and the Principals pursuant
to this Section 3.5(f)(iii) as to any modification to the terms of the Preferred
A Interest and the Preferred B Interest shall be binding on the Members.

                           (iv)     For purposes of this Section 3.5,

                                    (A)     the terms of any refinancing or 
modification of the Senior Debt or the Subordinated Debt will be conclusively
deemed not to modify the structure of the Senior Debt or the Subordinated Debt
in a manner that is adverse to the Principals if, within twenty-one days after
the delivery to the Principals and their legal counsel of the applicable
refinancing or modification proposal and any other information concerning the
proposed refinancing or modification that the Principals shall have reasonably
requested within ten days after their receipt of such proposal, the Principals
do not receive and deliver to Insight an opinion of the Principals' legal
counsel that, in its opinion, consummation of such refinancing or 

                                      -22-
<PAGE>
 
modification on the terms proposed would modify the structure of the Senior Debt
or the Subordinated Debt in a manner that would increase by more than a de
minimis amount the likelihood of those adverse tax consequences to the
Principals that were intended to be avoided by the Senior Debt and the
Subordinated Debt, as it will exist at the Closing; and

                                    (B)   the terms of any refinancing or 
modification of the Senior Debt or the Subordinated Debt will be conclusively
deemed to modify the structure of the Senior Debt or the Subordinated Debt in a
manner that is adverse to the Principals if, within twenty-one days after the
delivery to the Principals and their legal counsel of the applicable refinancing
or modification proposal and any other information concerning the proposed
refinancing or modification that the Principals shall have reasonably requested
within ten days after their receipt of such proposal, the Principals receive and
deliver to Insight an opinion of the Principals' legal counsel that, in its
opinion, consummation of such refinancing or modification on the terms proposed
would modify the structure of the Senior Debt or the Subordinated Debt in a
manner that would increase by more than a de minimis amount the likelihood of
those adverse tax consequences to the Principals that were intended to be
avoided by the Senior Debt and the Subordinated Debt, as it will exist at the
Closing.

                           (v) The Principals agree that any legal counsel from
which the Principals request an opinion described in Section 3.5(f)(iv) will be
reasonably satisfactory to Insight.

                           (vi) The Principals may not elect to require that
Insight or a Person designated by Insight purchase all of the outstanding
membership interests in the Shareholders pursuant to Section 3.5(a)(iv), Section
3.5(a)(v), or Section 3.5(b)(iii) unless, at the time that the Principals make
such election:

                                    (A)   all outstanding stock of Central 
shall have been duly and validly issued and shall be fully paid and
nonassessable;

                                    (B)    Central shall have no liabilities 
other than the Senior Debt, liabilities arising under this Agreement or under
any other agreement between Central and the Company, Insight, or any Affiliate
of the Company or Insight, liabilities incurred at the direction of Insight,
directly or indirectly, through its control over the business and affairs of
Central, and other liabilities (such as accrued administrative expenses) that
are not significant in amount and for which the Principals agree to indemnify
Insight, on terms reasonably satisfactory to Insight;

                                    (C)    Central shall have no assets other 
than its equity interest in the Company, contractual rights arising under any of
the Loan Documents, this Agreement, and any other agreement between Central and
the Company, Insight, or any Affiliate of the Company or Insight, assets
acquired at the direction of Insight, directly or indirectly, through its
control over the business and affairs of Central, and other assets (such as
internal corporate records) that are not significant in amount;

                                      -23-
<PAGE>
 
                                    (D)    all of the outstanding shares of 
Central shall be free and clear of all claims, liabilities, security interests,
mortgages, liens, pledges, conditions, charges, and encumbrances of any nature
whatsoever, other than liens securing the Senior Debt, the Subordinated Debt,
and any other obligations and liabilities arising under the Loan Documents;

                                    (E)   all outstanding membership interests
of the Shareholders shall have been duly and validly issued and shall be fully
paid and nonassessable;

                                    (F)   the Shareholders shall have no
liabilities other than the Subordinated Debt, liabilities arising under any
agreement between the Shareholders and Central, the Company, Insight, or any
Affiliate of the Company or Insight, liabilities incurred at the direction of
Insight, directly or indirectly, through its management of the Shareholders, and
other liabilities (such as accrued administrative expenses) that are not
significant in amount and for which the Principals agree to indemnify Insight,
on terms reasonably satisfactory to Insight;

                                    (G)    the Shareholders shall have no assets
other than their equity interests in Central, the LLC Mirror Notes, contractual
rights arising under any of the Loan Documents, any agreement between the
Shareholders, and Central, the Company, Insight, or any Affiliate of the Company
or Insight, assets acquired at the direction of Insight, directly or indirectly,
through its management of the Shareholders, and other assets (such as internal
corporate records) that are not significant in amount; and

                                    (H)    all of the outstanding membership 
interests of the Shareholders shall be free and clear of all claims,
liabilities, security interests, mortgages, liens, pledges, conditions, charges,
and encumbrances of any nature whatsoever, other than liens securing the Senior
Debt, the Subordinated Debt, and any other obligations and liabilities arising
under the Loan Documents.

                           (vii) If the Principals elect to require that Insight
or a Person designated by Insight purchase all of the outstanding membership
interests in the Shareholders pursuant to Section 3.5(a)(iv), Section 3.5(a)(v),
or Section 3.5(b)(iii), then (A) the Principals covenant that the conditions
specified in Section 3.5(f)(vi) will also be satisfied at the closing of the
purchase and sale of all of the outstanding membership interests in the
Shareholders, and (B) it shall be a condition to the purchase by Insight or a
Person designated by Insight of the outstanding membership interests in the

satisfied at the closing.

                           (viii) At Insight's request, Central and the
Principals agree to join in making an election under Code Section 338(h)(10)
with respect to the deemed purchase and sale of the shares of Central resulting

Shareholders pursuant to Section 3.5(a)(iv), Section 3.5(a)(v), or Section
3.5(b)(iii).

                         SECTION 4. CASH DISTRIBUTIONS

         4.1  Distributions Prior to Liquidation.

                  (a)      Distributions Generally.  Except as provided in 
Section 10.2(d), the Company shall make cash distributions as follows:

                           (i)      First, on each Guaranteed Payment Date,
commencing on the first Guaranteed Payment Date after the Closing, so long as
the Preferred A Interest is outstanding, the Company shall distribute to the
holder of the Preferred A Interest (A) on the first such date, a pro rata
portion of the Guaranteed Payment Amount, based on the ratio of the number of
days between the Closing Date and such date to the number of days between the
preceding Guaranteed Payment Date (although prior to the Closing Date) and such
date, computed on the basis of a 360-day year of twelve 30-day months, and (B)
on each other such date, the Guaranteed Payment Amount.

                           (ii) Second, on each Preferred A Distribution Date,
commencing on the first Preferred A Distribution Date after the Closing, so long
as the Preferred A Interest is outstanding, the Company shall distribute to the
holder of the Preferred A Interest the Preferred A Preference Amount.

                           (iii) Third, on each Preferred B Distribution Date,
commencing on the first Preferred B Distribution Date after the Closing, so long
as the Preferred B Interest is outstanding, the Company shall distribute to the
holder of the Preferred B Interest the Preferred B Preference Amount; provided,
however, that on any such Preferred B Distribution Date falling prior to the
Preferred B PIK Termination Date, the Company shall, in lieu of making such
distribution, accrue such amount, and any such accrued and unpaid amount shall
be added to the Preferred B Capital Amount.

                           (iv) Fourth, no less than three days prior to April
15 of each year, the Company shall distribute to each Member holding a Common
Interest, the excess of such Member's Tax Amount over the amounts previously
distributed to such Member under this Section 4.1(a)(iv), including Estimated
Tax Distributions (the "April Distribution"). If the Company's taxable income
for any year is increased above the amount used to compute the April
Distribution as a result of an adjustment deemed necessary by the Company or as
the result of a tax audit, the Company shall distribute to the Members holding
the Common Interests such amount as the Management Committee shall determine is
appropriate, in its good faith discretion, taking into account the respective
additional federal, state, and local tax liability of the Members as a result of
such increase and any related penalties and interest. The Company shall also
make distributions ("Estimated Tax Distributions") for the payment of taxes at
such times as either Member would be required to pay federal estimated taxes in
an amount not in excess of the Company's good faith estimate of the Tax Amount
for the period to which such estimated taxes relate. Notwithstanding anything to
the contrary herein, distributions under this Section 4.1(a)(iv) shall be made
in proportion to the Members' Percentage Interests.

                                      -25-
<PAGE>
 
                           (v)      Fifth, on each Management Return Payment 
Date, commencing on the first Management Return Payment Date after the Closing,
the Company shall distribute to the Manager the Management Return.

                           (vi)     Thereafter, at such times and in such 
amounts as the Management Committee may determine, to the Members holding Common
Interests in proportion to their Percentage Interests.

                  (b)      Late Distributions.

                           (i)      If the Company fails to make any
distribution required to be made pursuant to Section 4.1(a)(i) on or before the
applicable Guaranteed Payment Date, then the Guaranteed Payment Amount payable
with respect to that Guaranteed Payment Date shall be increased at a rate per
year equal to the Preferred A Rate for the number of days from the applicable
Guaranteed Payment Date to the date on which the required distribution is
actually made.

                           (ii) If the Company fails to make any distribution
required to be made pursuant to Section 4.1(a)(ii) on or before the applicable
Preferred A Distribution Date, then the amount to be distributed with respect to
that Preferred A Distribution Date shall be increased at a rate per year equal
to the Preferred A Rate for the number of days from the applicable Preferred A
Distribution Date to the date on which the required distribution is actually
made.

                           (iii) If the Company fails to make any distribution
required to be made pursuant to Section 4.1(a)(iii) on or before the applicable
Preferred B Distribution Date, then the amount to be distributed with respect to
that Preferred B Distribution Date shall be increased at a rate per year equal
to the Preferred B Rate for the number of days from the applicable Preferred B
Distribution Date to the date on which the required distribution is actually
made; provided, however, that this Section 4.1(b)(iii) shall apply only to
distributions required to be made on Preferred B Distribution Dates occurring on
or after the Preferred B PIK Termination Date.

                           (iv) If the Company fails to make any distribution
required to be made pursuant to Section 4.1(a)(v) on or before the applicable
Management Return Payment Date, then the amount to be distributed with respect
to that Management Return Payment Date shall bear interest at the Preferred A
Rate from that Management Return Payment Date to the date that the required
distribution is actually made.

                  (c) Borrowings for Guaranteed Payments. To the extent the
Company does not have sufficient cash to make the distribution required to be
made pursuant to Section 4.1(a)(i) then, unless the Manager or the Principals
object, the Manager shall cause the Company to borrow funds in order to make
such distributions in a full and timely manner.

                  (d) Treatment of Guaranteed Payments. The distributions
provided for in Section 4.1(a)(i) are required to be made without regard to the
income of the Company and shall be treated as guaranteed payments as described
in Code Section 707(c). No Member shall take a position inconsistent with such
treatment.

                                      -26-

                  (e) Determination of Tax Amount. For purposes of Section
4.1(a)(iv), the "Tax Amount" of a Member holding a Common Interest means, the
sum of such Member's tax liabilities for all previous Fiscal Years, determined
in accordance with, and subject to, the following:

                           (i)      The tax liability of a Member holding a 
Common Interest for any Fiscal Year shall be the greater of such Member's
Regular Tax Liability or its AMT Liability for such Fiscal Year.

                           (ii)     The "Regular Tax Liability" of a Member 
holding a Common Interest for any Fiscal Year shall be determined separately for
ordinary income and each character of capital gain income to which separate
federal income tax rates may apply, and for each such type of income shall be
computed as the product of (A) the excess of (1) the aggregate amount of taxable
income (if any) allocated to such Member with respect to its Common Interest in
such Fiscal Year over (2) the aggregate amount of taxable losses (if any)
allocated to such Member with respect to its Common Interest for all prior
Fiscal Years since the beginning of the Company and not previously taken into
account for purposes of computing such Member's Tax Amount, and (B) the highest
marginal combined federal, state, and local tax rate (taking into count the
provisions of Code Section 68) imposed on an individual resident in New York
City for income of such type.

                           (iii)    The "AMT Liability" of a Member holding a
Common Interest for any Fiscal Year shall be computed as the product of (A) the
aggregate amount of alternative minimum taxable income (if any) allocated to
such Member with respect to its Common Interest in such Fiscal Year (less any
alternative minimum tax losses allocated to such Member with respect to its
Common Interest for all prior Fiscal Years since the beginning of the Company
and not previously taken into account for purposes of computing such Member's
Tax Amount) and (B) the highest marginal combined federal, state, and local tax
rate imposed on the alternative minimum taxable income of an individual resident
in New York City (taking into account the lack of deductibility for state and
local taxes under the federal alternative minimum tax).

                           (iv)     For purposes of determining a Member's 
Regular Tax Liability or AMT Liability, any Member who receives a Common
Interest in a transfer with respect to which an election under Code Section 754
has not been made (or is not in effect) shall be deemed to have been allocated
any taxable losses or income allocated to the transferor of such Common
Interest. For purposes of determining a Member's April Distribution, any Member
who receives a Common Interest in a transfer with respect to which an election
under Code Section 754 has not been made (or is not in effect) shall be deemed
to have received any distributions made pursuant to Section 4.1(a)(iv) to the
transferor of such Common Interest.

                           (v)      Notwithstanding anything to the contrary 
herein, for purposes of calculating a Member's Tax Amount under this Section
4.1(e), the taxable income or taxable loss (including alternative minimum
taxable income and alternative minimum taxable loss) allocated to a Member shall
exclude (and no April Distributions or Estimated Tax Distributions shall be made
with respect to) (A) gain allocated to any Member with respect to the sale,
exchange, or other actual or deemed disposition of any assets contributed to the
Company by either Member, (B) gross income 

                                      -27-
<PAGE>
 
allocated to the holder of the Preferred A Interest with respect to
distributions made under Section 4.1(a)(i), (C) gross income allocated to the
holder of the Preferred A Interest under Section 5.2(h), (D) gross income
allocated to the holder of the Preferred B Interest under Section 5.2(i), and
(E) gross income allocated to the Manager under Section 5.2(k).

                  (f) Delaying Distributions. If (i) any default (other than a
notification or delivery default) shall have occurred and be continuing under
any of the Loan Documents, or if Insight in good faith determines that such a
default under any of the Loan Documents is reasonably likely to occur, and (ii)
Insight determines in good faith that, as a result of such existing or
anticipated default, it would be in the best interests of the Company for the
Company not to make any distribution required pursuant to Section 4.1(a)(i),
Section 4.1(a)(ii), or Section 4.1(a)(iii), and (iii) Insight notifies the
Principals in writing that it has made such determination, then Insight may
cause the Company not to make such distribution until such time as Insight shall
have determined that it is no longer in the best interests of the Company for
the Company not to make such distribution. To the extent, but only for so long
as, Insight is authorized by this Section 4.1(f) to cause the Company not to
make such distribution, then (i) neither Insight nor the Company shall have any
liability to the holder of the Preferred A Interest or the holder of the
Preferred B Interest as a result of the Company's failure to make any
distribution required pursuant to Section 4.1(a)(i), Section 4.1(a)(ii), or
Section 4.1(a)(iii), and (ii) the Company's failure to make such distribution
shall not constitute a Capital Default. The provisions of Section 4.1(b) shall
apply to the Company's failure to make any distribution required pursuant to
Section 4.1(a)(i), Section 4.1(a)(ii), or Section 4.1(a)(iii) notwithstanding
Insight's rights under this Section 4.1(f) to cause the Company not to make any
such distribution.

         4.2  Withholding.

         All amounts withheld pursuant to the Code or any provision of any state
or local tax law with respect to any payment or distribution to the Company or
the Members shall be treated as amounts distributed to Members pursuant to
Section 4 for all purposes of this Agreement.

         4.3  Redemption.

                  (a)      Redemption of Preferred B Interest.

                           (i)      Subject to Section 4.3(a)(iv), the Company
shall redeem the Preferred B Interest in full on the tenth anniversary of the
Closing Date. Subject to Section 4.3(a)(iv), the Company shall redeem the
Preferred B Interest in full if (A) the Discount Notes shall have been
accelerated, (B) the holders of the Discount Notes shall have commenced the
enforcement of any remedies available to them under any agreement under which
shares of Central and the LLC Mirror Notes (as defined in the offering
memorandum for the Discount Notes) are pledged as security for the Discount
Notes, (C) at least ten days shall have elapsed since the maturity or
acceleration of the Discount Notes, and (D) the holders of the Discount Notes,

                                      -28-
<PAGE>
 
Notes (as defined in the offering memorandum for the Discount Notes) are pledged
as security for the Discount Notes.

                           (ii)     The Company may redeem the Preferred B 
Interest, in whole or in part, at any time at its option if (A) the Principals
shall have received an opinion of their legal counsel that the redemption of the
Preferred B Interest would not, in its opinion, increase by more than a de
minimis amount the likelihood of those adverse tax consequences to the
Principals that were intended to be avoided by the Senior Debt and the
Subordinated Debt, as it will exist at the Closing, and (B) the Borrowers would
be permitted under the Loan Documents to use the proceeds of the redemption of
the Preferred B Interest to repay or purchase the Subordinated Debt.

                           (iii)    Except as expressly provided in this Section
4.3(a), the Company may not redeem the Preferred B Interest, in whole or in
part, without the consent of the Principals.

                           (iv)     Notwithstanding Section 4.3(a)(i), the 
Company shall not redeem the Preferred B Interest if the Company is required to
redeem the Preferred A Interest pursuant to Section 4.3(b)(i) and has not yet
done so.

                           (v)      If the Company redeems all or part of the 
Preferred B Interest pursuant to this Section 4.3(a), the redemption price shall
equal the sum of (A) the amount that would be distributed to the holder of the
Preferred B Interest with respect to the redeemed portion of the Preferred B
Interest pursuant to Section 10.2(d)(iii)(C) upon dissolution and liquidation of
the Company, assuming that the distribution pursuant to Section 10.2(d)(iii)(C)
was made on the date of such redemption and that the proceeds of the liquidation
of the Company were sufficient to permit the Company to make the full
distribution provided for in Section 10.2(d)(iii)(C), plus (B) the amount of any
premium required to be paid by the Borrowers to the holders of the Subordinated
Debt in connection with the Borrowers' use of the proceeds of the redemption of
the Preferred B Interest to repay or purchase the Subordinated Debt.

                  (b)      Redemption of Preferred A Interest.

                           (i)      The Company shall redeem the Preferred A 
Interest in full if (A) the Senior Notes shall be payable in full (either upon
reaching their stated maturity or upon their acceleration), (B) the holders of
the Senior Notes shall have commenced the enforcement of any remedies available
to them under any agreement under which the Preferred A Interest is pledged as
security for the Senior Notes, (C) at least ten days shall have elapsed since

Senior Notes, acting on their own behalf or through the trustee of the Senior
Notes, shall have requested redemption of the Preferred A Interest in accordance
with the provisions of any agreement under which the Preferred A Interest is
pledged as security for the Senior Notes.

                           (ii)     The Company may redeem the Preferred A 
Interest, in whole or in part, at any time at its option if (A) the Principals
shall have received an opinion of their legal counsel that the redemption of the
Preferred A Interest would not, in its opinion, increase by more than a de
minimis amount the likelihood of those adverse tax consequences to the
Principals that 

                                      -29-
<PAGE>
 
were intended to be avoided by the Senior Debt and the Subordinated Debt, as it
will exist at the Closing, and (B) the Borrowers would be permitted under the
Loan Documents to use the proceeds of the redemption of the Preferred A Interest
to repay or purchase the Senior Debt.

                           (iii)    Except as expressly provided in this Section
4.3(b), the Company may not redeem the Preferred A Interest, in whole or in
part, without the consent of the Principals.

                           (iv) If the Company redeems all or part of the
Preferred A Interest pursuant to this Section 4.3(b), the redemption price shall
equal the sum of (A) the amount that would be distributed to the holder of the
Preferred A Interest with respect to the redeemed portion of the Preferred A
Interest pursuant to Section 10.2(d)(iii)(A) and Section 10.2(d)(iii)(B) upon
dissolution and liquidation of the Company, assuming that the distributions
pursuant to Section 10.2(d)(iii)(A) and Section 10.2(d)(iii)(B) were made on the
date of such redemption and that the proceeds of the liquidation of the Company
were sufficient to permit the Company to make the full distributions provided
for in Section 10.2(d)(iii)(A) and Section 10.2(d)(iii)(B), plus (B) the amount
of any premium required to be paid by the Borrowers to the holders of the Senior
Debt in connection with the Borrowers' use of the proceeds of the redemption of
the Preferred A Interest to repay or purchase the Senior Debt.

         4.4  Certain Remedies.

                  (a)      As used in this Agreement, a "Capital Default" means:

                           (i)      Except as provided in Section 4.1(f), the
failure of the Company to make any distribution required pursuant to Section
4.1(a)(i), Section 4.1(a)(ii), or Section 4.1(a)(iii) on or before the
applicable Guaranteed Payment Date, Preferred A Distribution Date, or Preferred
B Distribution Date (other than a distribution pursuant to Section 4.1(a)(iii)
required to be made before the Preferred B PIK Termination Date), if on such
date the Company had Distributable Cash (taking into account any other
distributions pursuant to Section 4.1(a)(i), Section 4.1(a)(ii), or Section
4.1(a)(iii) that were made on such date and after giving effect to any
borrowings pursuant to Section 4.1(c)), in an amount at least equal to the
entire amount of such distribution; provided, however, that the failure to make
any such distribution shall not constitute a Capital Default (A) if a Person
designated by the Principals shall have become an additional Manager pursuant to
Section 4.4(b)(ii) and such Person shall have had the power to cause such
distribution to be made or (B) to the extent such distribution would violate any
covenant contained in any agreement or other instrument, including any note or
indenture, evidencing any indebtedness of the Company to a Person that is not an
Affiliate of either Member or pursuant to which any such indebtedness of the
Company exists or is outstanding; or

                           (ii)     The redemption of the Preferred A Interest
or the Preferred B Interest in violation of Section 4.3; provided, however, that
such redemption shall not constitute a Capital Default if a Person designated by
the Principals shall have become an additional Manager pursuant to Section
4.4(b)(ii) and such Person shall have caused such redemption to occur; or

                                      -30-
<PAGE>
 
                           (iii)    The willful and intentional breach by
Insight of any of its obligations under Section 3.5.

                  (b)      Upon the occurrence of a Capital Default:

                           (i)      Insight shall indemnify, defend, and hold 
harmless Central, each other Borrower, and each of the Principals, from any
liability, loss, or damage incurred by any such Person, including costs and
attorneys' fees (which attorneys' fees may be paid as incurred) and any amounts
expended in the settlement of any claims of liability, loss, or damage, and
including any tax liabilities incurred as a result of the receipt of any
indemnification payment under this Section 4.4(b)(i), that either (A) arise out
of or result from such Capital Default or (B) to the extent such Capital Default
consists of an action taken to modify the structure of the Senior Debt or the
Subordinated Debt, arise out of or result from any failure of the Senior Debt
and the Subordinated Debt to prevent those adverse tax consequences to the
Principals that were intended to be avoided by the Senior Debt and the
Subordinated Debt, as it will exist at the Closing. Insight acknowledges and
agrees that any Capital Default could result in significant tax liabilities
being incurred by the Principals, and that such tax liabilities are included in
the possible damages for which the Principals would be entitled to indemnity
under this Section 4.4(b)(i).

                           (ii)     Subject to the receipt of any required
consents, approvals, waivers, or authorizations of governmental authorities, (A)
the number of Representatives constituting the Management Committee shall be
increased to six, three of which shall be appointed by holders of a majority of
the outstanding Voting Interests and three of which shall be appointed by the
Principals, and (B) a Person designated by the Principals shall become an
additional Manager of the Company and shall have the authority to exercise, to
the same extent as Insight, all powers designated in this Agreement as powers of
the Manager or delegated to the Manager by the Management Committee, including
the power to cause distributions to be made to the Members in accordance with
Section 4.1(a)(i), Section 4.1(a)(ii), and Section 4.1(a)(iii) or to cause the
Preferred A Interest or the Preferred B Interest to be redeemed pursuant to
Section 4.3.

                  SECTION 5. ALLOCATIONS OF PROFITS AND LOSSES

         5.1  Allocations of Net Profit and Net Loss.

                  (a) Allocations of Net Profit. For purposes of maintaining
Capital Accounts, except as otherwise provided in this Agreement, Net Profit for
each taxable year (or portion thereof) shall be allocated to the Members as
follows:

                           (i)      First, to the Members to reverse any 
allocations of Net Losses to the Members pursuant to Section 5.1(b)(iii) and
Section 5.1(b)(ii) (in reverse order to the order in which such Net Losses were
allocated to the Members) to the extent not previously reversed under this
Section 5.1(a)(i); and

                           (ii)     Thereafter, to the Members holding Common 
Interests in proportion to their Percentage Interests.

                                      -31-
<PAGE>
 
                  (b) Allocations of Net Loss. Net Loss for each taxable year
(or portion thereof) shall be allocated to the Members as follows:

                           (i)      First, to the Members in proportion to 
their Percentage Interests; provided, however, that no allocation pursuant to
this Section 5.1(b)(i) shall reduce a Member's Adjusted Capital Account balance
below zero;

                           (ii)     Second, to the Members in proportion to 
their positive Adjusted Capital Account balances until each Member's Adjusted
Capital Account balance is at zero; and

                           (iii)    Thereafter, to all Members in proportion to
their Percentage Interests.

         5.2  Special Provisions Regarding Allocations of Income and Loss.

         The following special allocations for purposes of maintaining Capital
Accounts shall be made in the following order:

                  (a) Minimum Gain Chargeback. Except as otherwise provided in
Treasury Regulations Section 1.704-2(f), notwithstanding any other provision of
this Section 5, if there is a net decrease in Partnership Minimum Gain for any
Fiscal Year, each Member shall be specially allocated items of Company income
and gain for such Fiscal Year (and if necessary for succeeding Fiscal Years) in
an amount equal to such Member's share of the net decrease in Partnership
Minimum Gain, determined in accordance with Treasury Regulations Section
1.704-2(g). Allocations made pursuant to the preceding sentence shall be made in
proportion to the respective amounts required to be allocated to each Member
pursuant thereto. The items of Company income and gain to be allocated pursuant
to this Section 5.2(a) shall be determined in accordance with Treasury
Regulations Section 1.704-2(f)(6) and Treasury Regulations Section
1.704-2(j)(2). The amount of Partnership Minimum Gain shall be determined in
accordance with Treasury Regulations Section 1.704-2(d). This Section 5.2(a) is
intended to comply with the minimum gain chargeback requirement in Treasury
Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

                  (b) Partner Minimum Gain Chargeback. Except as otherwise
provided in Treasury Regulations Section 1.704-2(i)(4), notwithstanding any
other provision of this Section 5 except Section 5.2(a), if during any Fiscal
Year there is a net decrease in Partner Nonrecourse Debt Minimum Gain, each
Member that has a share of that Partner Nonrecourse Debt Minimum Gain
(determined in accordance with Treasury Regulations Section 1.704-2(i)(5)) as of
the beginning of such Fiscal Year shall be allocated items of Company income and
gain for the Fiscal Year (and, if necessary, for succeeding Fiscal Years) equal
to that Member's share of the net decrease in the Partner Nonrecourse Debt
Minimum Gain (determined in accordance with Treasury Regulations Section
1.704-2(i)(4)). Allocations pursuant to the preceding sentence shall be made in
proportion to the respective amounts required to be allocated to each Member
pursuant thereto. The items of Company income and gain to be allocated pursuant
to this Section 5.2(b) shall be determined in accordance with Treasury
Regulations Section 1.704-2(i)(4) and Treasury Regulations Section

                                      -32-
<PAGE>
 
1.704-2(j)(2). The amount of Partner Nonrecourse Debt Minimum Gain shall be
determined in accordance with Treasury Regulations Section 1.704-2(i)(3). This
Section 5.2(b) is intended to comply with the minimum gain chargeback
requirement in Treasury Regulations Section 1.704-2(i)(4) and shall be
interpreted consistently therewith.

                  (c) Nonrecourse Deductions. Nonrecourse Deductions for any
Fiscal Year or other period shall be specially allocated between the Members in
proportion to their Percentage Interests.

                  (d) Partner Nonrecourse Deductions. Any Partner Nonrecourse
Deductions for any Fiscal Year or other period shall be specially allocated to
the Member that bears the economic risk of loss with respect to the Partner
Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable
in accordance with Treasury Regulations Section 1.704-2(i).

                  (e) Qualified Income Offset. If either Member unexpectedly
receives any adjustments, allocations, or distributions described in Treasury
Regulations Sections 1.704-1(b)(2)(ii)(d)(4), 1.704- 1(b)(2)(ii)(d)(5), or
1.704-1(b)(2)(ii)(d)(6), items of Company income and gain shall be specially
allocated to such Member in an amount and manner sufficient to eliminate, to the
extent required by the Treasury Regulations, the Adjusted Capital Account of
such Member as quickly as possible; provided, however, that an allocation
pursuant to this Section 5.2(e) shall be made if and only to the extent that
such Member would have an Adjusted Capital Account after all other allocations
provided for in this Section 5 have been tentatively made as if this Section
5.2(e) were not in this Agreement.

                  (f) Curative Allocations. The allocations set forth in the
foregoing provisions of this Section 5.2 (the "Regulatory Allocations") are
intended to comply with certain requirements of the Treasury Regulations. It is
the intent of the Members that, to the extent possible, all Regulatory
Allocations shall be offset either with other Regulatory Allocations or with
special allocations of other items of Company income, gain, loss, or deduction
pursuant to this Section 5.2. Therefore, notwithstanding any other provision of
this Section 5 (other than the Regulatory Allocations), the Company shall make
such offsetting special allocations of Company income, gain, loss, or deduction
in whatever manner that the Management Committee determines is appropriate so
that, after such offsetting allocations are made, each Member's Capital Account
balance is, to the extent possible, equal to the Capital Account balance such
Member would have had if the Regulatory Allocations were not in this Agreement.
In exercising its discretion under this Section 5.2(f), the Management Committee
shall take into account future Regulatory Allocations under Section 5.2(a) and
Section 5.2(b) that, although not yet made, are likely to offset other
Regulatory Allocations previously made under Section 5.2(c) and Section 5.2(d).

                  (g) Recharacterization of Payments. If any payments or
expenses deducted for federal income tax purposes by a Member are
recharacterized by a final determination of the Internal Revenue Service as
nondeductible contributions to the Company, any corresponding items of loss or
deduction available to the Company shall be allocated to such Member so that, to
the extent possible, such Member has the same tax consequences as it would have
had if such payments or expenses had been deductible by such Member.

                                      -33-
<PAGE>
 
                  (h) Allocations with Respect to Preferred A Interest. There
shall be allocated to the holder of the Preferred A Interest an amount of gross
income of the Company for any taxable year equal to the cumulative distributions
made with respect to the Preferred A Interest pursuant to Section 4.1(a)(ii)
(including any late payments on such distributions pursuant to Section
4.1(b)(ii)) in such taxable year.

                  (i) Allocations with Respect to Preferred B Interest. There
shall be allocated to the holder of the Preferred B Interest an amount of gross
income of the Company for any taxable year equal to the sum of (A) cumulative
distributions made with respect to the Preferred B Interest pursuant to Section
4.1(a)(iii) (including any late payments on such distributions pursuant to
Section 4.1(b)(iii)) in such taxable year and (B) the cumulative amount of
increases in the Preferred B Capital Amount pursuant to Section 4.1(a)(iii)
occurring during such taxable year.

                  (j)      Allocations to Central.

                           (i)      There shall be allocated to Central an
amount of gross income of the Company for any taxable year equal to $513,400
(pro-rated for any taxable year having less than 365 days), but only to the
extent that the cumulative allocations made under this Section 5.2(j)(i) (in all
taxable years) do not exceed $4,107,200.

                           (ii)     There shall be allocated to Central an
amount of gross income of the Company for any taxable year equal to $161,300
(pro-rated for any taxable year having less than 365 days), but only to the
extent that the cumulative allocations made under this Section 5.2(j)(ii) (in
all taxable years) do not exceed $1,613,000.

                  (k) Allocations to Manager. There shall be allocated to the
Manager an amount of gross income of the Company for any taxable year equal to
the cumulative distributions made to the Manager pursuant to Section 4.1(a)(v)
during such taxable year.

                  (l) Amortization Deductions Attributable to Certain Intangible
Assets. Amortization deductions attributable to intangible assets contributed to
the Company by Central that have an initial Gross Asset Value in excess of
initial adjusted basis for federal income tax purposes shall be allocated as
follows: (i) in any taxable year, amortization deductions equal to the
amortization deductions for income tax purposes available with respect to such
assets shall be allocated to Insight, (ii) in any taxable year, amortization
deductions in excess of amortization deductions for income tax purposes shall be
allocated to Central, provided that the cumulative allocations made to Central
under this clause shall not exceed the initial Gross Asset Value of such assets
reduced by $30 million, provided further that no allocation pursuant to this
clause shall reduce Central's Adjusted Capital Account balance below zero, (iii)
thereafter, all amortization deductions in respect of such assets shall be
allocated to Insight, provided that no allocation pursuant to this clause shall
reduce Insight's Adjusted Capital Account balance below zero, and (iv) any
remaining amortization deductions available with respect to such assets shall be
allocated to Central to the extent of Central's positive Adjusted Capital
Account balance and thereafter to the Members in accordance with their
Percentage Interests. Any "book-up" or recapture of the amortization 

                                      -34-
<PAGE>
 
deductions described in the preceding sentence shall be allocated to the Member
to which the previously claimed deduction was allocated.

                  (m) Allocations Upon Liquidation. Notwithstanding anything to
the contrary herein, upon a liquidation of the Company, allocations of Net
Profit and Net Loss, and if necessary, of gross income and deductions, shall be
made so that, after such allocations have been made, the Capital Accounts of the
Members will equal as closely as possible the amounts to be distributed to the
Members pursuant to Section 10.2(d)(iii), with distributions under Section
10.2(d)(iii)(E) made in proportion to each Member's Percentage Interests.

         5.3  Section 754 Adjustments.

         To the extent any adjustment to the adjusted tax basis of any asset of
the Company pursuant to Code Section 734(b) or Code Section 743(b) is required,
pursuant to Treasury Regulations Section 1.704- 1(b)(2)(iv)(m), to be taken into
account in determining Capital Accounts, the amount of such adjustment shall be
treated as an item of gain (if the adjustment increases the basis of the asset)
or loss (if the adjustment decreases such basis), and such gain or loss shall be
specially allocated to the Members in a manner consistent with the manner in
which their Capital Accounts are required to be adjusted pursuant to such
section of the Treasury Regulations. An election under Code Section 754 shall be
made by the Company only with the consent of the Principals.

         5.4  Allocations for Tax Purposes.

                  (a) Except as otherwise provided herein, for federal income
tax purposes, (i) each item of income, gain, loss and deduction shall be
allocated between the Members in the same manner as its correlative items of
"book" income, gain, loss or deduction is allocated pursuant to Section 5.1,
Section 5.2, and Section 5.3, and (ii) each tax credit shall be allocated to the
Members in the same manner as the receipt or expenditure giving rise to such
credit is allocated pursuant to Section 5.1, Section 5.2, and Section 5.3.

                  (b) In accordance with Code Section 704(c) and the Treasury
Regulations thereunder, income, gain, loss, and deduction with respect to any
property contributed to the capital of the Company shall, solely for tax
purposes, be allocated between the Members so as to take account of any
variation between the adjusted basis of such property to the Company for federal
income tax purposes and its initial Gross Asset Value. The Company shall use the
"traditional method" of making Code Section 704(c) allocations (as described in
Treasury Regulations Section 1.704-3(b)).

                  (c) If the Gross Asset Value of any asset of the Company is
adjusted pursuant to paragraph (ii) of the definition of Gross Asset Value,
subsequent allocations of income, gain, loss, and deduction with respect to such
asset shall take account of any variation between the adjusted basis of such
asset for federal income tax purposes and its Gross Asset Value in the same
manner as under Code Section 704(c) and the Treasury Regulations thereunder.

                  (d) Any elections or other decisions relating to allocations
described in Section 5.4(b) and Section 5.4(c) shall be made by the Management
Committee in any manner that reasonably reflects the purpose and intention of
this Agreement. Allocations pursuant to Section 5.4(b) and Section 5.4(c) are
solely for purposes of federal, state, and local taxes and shall not affect, or
in any way be taken into account in computing, either Member's Capital Account
or share of Net Profit, Net Loss, other items, or distributions pursuant to any
provision of this Agreement.

         5.5  Allocations Following a Transfer of Membership Interest.

         If a Membership Interest is transferred in accordance with Section 9 of
this Agreement, Net Profit and Net Loss shall be allocated between the periods
before and after the transfer by the interim closing of the Company books method
set forth in Treasury Regulation Section 1.706-1(c)(2)(ii). As of the date of
such transfer, the transferee shall succeed to the Capital Account of the
transferor with respect to the transferred Membership Interest. This paragraph
shall apply for purposes of computing a Member's Capital Account and for federal
income tax purposes.

                   SECTION 6. AUTHORITY OF THE MANAGER; OTHER
                           MATTERS AFFECTING MANAGER

         6.1 Authority of Manager.

         The Manager agrees that, except as otherwise expressly provided herein,
the Manager acting alone shall not give any consent to any matter or take any
other action as the Manager, including acting on behalf of or binding the
Company with respect to any matter in respect of which approval by the
Management Committee or the Members is required by the provisions of this
Agreement or the Act, unless such consent, matter, or other action shall first
have been adopted or approved by the Management Committee or the Members, as the
case may be, or authority to consent to such matter or to take such other action
shall have been expressly delegated to the Manager by the Management Committee
or the Members, as the case may be, in each case in accordance with the
provisions of this Agreement or the Act as applicable.

         6.2  Resignation as Manager.

                  (a) Insight may not resign as the Manager without the consent
of holders of a majority of the outstanding Voting Interests and the consent of
the Principals (except in the case of a Transfer of all of Insight's Membership
Interest that is permitted by this Agreement, including a Transfer pursuant to
Section 9.11, where the Assignee of Insight's Membership Interest has been
admitted as a substitute Member in accordance with Section 9.3). If holders of a
majority of the outstanding Voting Interests and the Principals consent to such
resignation, the Company shall dissolve in accordance with the provisions of
Section 10 unless, within ninety days after the resignation of Insight as the
Manager, all the Members and the Principals elect to continue the business of
the Company and agree to the appointment, effective as of the date of the
resignation of Insight as the Manager, of one or more new Managers.

                                      -36-
<PAGE>
 
                  (b) Any change in the identity of the Manager shall be subject
to and conditioned upon receipt of all necessary governmental approvals and
other material third-party consents.

                  (c) Without limiting any other rights or remedies that the
Company or Central may have at law or in equity, upon any resignation by Insight
as the Manager in violation of this Agreement, then, notwithstanding any other
provision of this Agreement to the contrary, no consent of Insight required
under any provision of this Agreement shall any longer be required and Central
shall be entitled to grant all such consents and take all actions relating to
the Company and its business.

         6.3  Tax Matters Member.

                  (a) The Manager is hereby designated as the Tax Matters Member
of the Company, as provided in Treasury Regulations pursuant to Code Section
6231 and analogous provisions of state law. Each Member, by the execution of
this Agreement, consents to such designation of the Tax Matters Member and
agrees to execute, certify, acknowledge, deliver, swear to, file, and record at
the appropriate public offices such documents as may be necessary or appropriate
to evidence such consent.

                  (b) The Manager, as the Tax Matters Member, is authorized to
represent the Company before taxing authorities and courts in tax matters
affecting the Company and the Members in their capacity as Members and is
entitled to take any actions on behalf of the Company in any such tax
proceedings that the Manager, in its reasonable business judgment, deems to be
in the best interests of the Company and the Members, except that, without the
written consent of Central and the Principals, the Manager shall not extend the
statute of limitations for assessment of tax deficiencies against the Members
with respect to adjustments to the Company's federal, state, and local tax
returns, agree to any deficiency or other adjustment of any kind that adversely
affects Central or any of the Principals, make any material tax elections, or
execute any agreements or other documents relating to or affecting any tax
matters that are binding on the Company or Central or any of the Principals;
provided, however, that intangible assets contributed to the Company by Central
that have an initial Gross Asset Value in excess of their initial adjusted basis
for federal income tax purposes shall be amortized over a 25-year period.

                  (c) To the extent and in the manner provided by applicable law
and Treasury Regulations, the Tax Matters Member shall furnish the name,
address, profits interest, and taxpayer identification number of each Member and
any Assignee to the Secretary of the Treasury or his delegate (the "Secretary").

                  (d) The Tax Matters Member shall notify each Member and each
Principal of any audit that is brought to the attention of the Tax Matters
Member by notice from the Internal Revenue Service, and shall forward to each
Member and each Principal copies of any written notices, correspondence,
reports, or other documents received by the Tax Matters Member in connection
with such audit within ten Business Days following its notification by the
Internal Revenue Service or its receipt, as the case may be. The Tax Matters
Member shall provide each Member and each Principal with reasonable advance
notice of, and shall afford each Member and each Principal the 

                                      -37-

right to participate in, any administrative proceedings or other material
discussions with the Internal Revenue Service, including any closing conference
with the examiner and any appeals conference, relating to the Company.

                  (e) The Tax Matters Partner shall, at the Company's expense,
cause all federal, state, local, and other tax returns and reports (including
amended returns) required to be filed by the Company or any Subsidiary to be
prepared and timely filed with the appropriate authorities. The Tax Matters
Partner shall cause all income or franchise tax returns or reports required to
be filed by the Company or any Subsidiary to be sent to each Member and each
Principal for review at least five Business Days prior to filing, and the Tax
Matters Partner shall afford each Member and each Principal a reasonable
opportunity to comment on any such return prior to filing.

                  (f) Any Member that receives a notice of an administrative
proceeding under Code Section 6223 relating to the Company shall promptly notify
the Tax Matters Member of the treatment of any Company item on such Member's
federal income tax return that is or may be inconsistent with the treatment of
that item on the Company's return.

                  (g) Any Member that enters into a settlement agreement with
the Secretary with respect to any Company item shall notify the Tax Matters
Member of such agreement and its terms within thirty days after its date, and
the Tax Matters Member shall notify each other Member and each Principal of the
settlement agreement within thirty days of such notification.

         6.4  Reimbursement of Expenses.

                  (a) The Company shall reimburse the Manager for all direct,
out-of-pocket expenses incurred by or on behalf of the Manager that directly
relate to its management of the business and operations of the Company,
including any such expenses incurred in connection with the management of the
Shareholders pursuant to the management agreements between the Shareholders and
Insight; provided, however, that the Manager shall not be entitled to
reimbursement from the Company for corporate overhead (including employee
bonuses and health, welfare, retirement, and other employee benefits and
overhead expenses of its corporate office management, development, internal
accounting, and finance management personnel).

                  (b) The Company shall reimburse the Borrowers for all direct,
out-of-pocket expenses incurred by or on behalf of the Borrowers in complying
with the terms of the Loan Documents (excluding any payment of principal or
interest under the Senior Debt or the Subordinated Debt). The Company shall pay,
or shall reimburse the Borrowers for, any amounts required to be paid by any
Borrower as a result of any indemnification or reimbursement obligation arising
under any of the Loan Documents or otherwise arising in connection with the
offer or sale of any of the Senior Debt or the Subordinated Debt.
Notwithstanding the foregoing, no Borrower shall be entitled to reimbursement
from the Company for costs and expenses incurred in connection with maintaining
the legal existence of any Borrower, preparing and filing tax returns and
reports on behalf of the Borrower, or any other similar recurring expenses.

                          SECTION 7. STATUS OF MEMBERS

         7.1  No Management and Control.

         Except as expressly provided in this Agreement, neither Member (other
than the Manager) shall take part in or interfere in any manner with the
control, conduct, or operation of the Company or have any right or authority to
act for or bind the Company or to vote on matters relating to the Company.

         7.2  Limited Liability.

         Neither Member shall be bound by or personally liable for the expenses,
liabilities, or obligations of the Company. In no event shall either Member be
required to make up a deficiency in its Capital Account upon the dissolution and
termination of the Company.

         7.3  Return of Distributions of Capital.

         A Member may, under certain circumstances, be required by law to return
to the Company, for the benefit of the Company's creditors, amounts previously
distributed. Neither Member shall be obligated by this Agreement to pay those
distributions to or for the account of the Company or any creditor of the
Company. However, if any court of competent jurisdiction holds that,
notwithstanding the provisions of this Agreement, a Member must return or pay
over any part of those distributions, the obligation shall be that of such
Member alone and not of the other Member. Any payment returned to the Company by
a Member or made directly by a Member to a creditor of the Company shall be
deemed a Capital Contribution by such Member.

         7.4  Specific Limitations.

         Neither Member shall have the right or power to (a) resign as a Member
(except in the case of a Transfer of all of a Member's Membership Interest that
is permitted by this Agreement, including a Transfer pursuant to Section 9.11,
where the Assignee of such Member's Membership Interest has been admitted as a
substitute Member in accordance with Section 9.3, and except as provided in
Section 6.2(a) with respect to the Manager), (b) reduce its Capital Contribution
except as a result of the dissolution of the Company or as otherwise provided by
law, or (c) demand or receive property other than cash in return for its Capital
Contribution. Except as otherwise set forth in this Agreement or in any
agreement permitted to be entered into under this Agreement with respect to the
purchase, redemption, retirement, or other acquisition of Membership Interests,
neither Member shall have priority over the other Member either as to the return
of its Capital Contribution or as to Net Profit, Net Loss, or distributions.
Other than upon the termination and dissolution of the Company as provided by
this Agreement, and except has provided in Section 4.3, there has been no time
agreed upon when the Capital Contribution of either Member will be returned.

         7.5  Issuance of Membership Interests.

         Subject to any approval that may be required by Section 8.5(b) and, if
such approval is required, in accordance with the terms thereof, the Manager may
issue additional Membership Interests to any Person and may admit to the Company
as additional Members the Persons acquiring such Membership Interests, if such
Persons were not previously admitted as Members. The Persons acquiring such
Membership Interests shall have the rights and be subject to the obligations
attributable to such Membership Interests in the form issued to them. A Person
admitted as a new Member shall only be entitled to distributions and allocations
of Net Profit and Net Loss attributable to the period beginning on the effective
date of its admission to the Company, and the Company shall attribute Net Profit
and Net Loss to the period before the effective date of the admission of a new
Member and to the period beginning on the effective date of the admission of a
new Member by the closing of the books method.

                      SECTION 8. MANAGEMENT OF THE COMPANY

         8.1  Creation of Management Committee.

                  (a) Except as otherwise expressly provided in this Agreement,
the business and operations of the Company shall be managed by a Management
Committee consisting of four Representatives, three of which shall be appointed
by holders of a majority of the outstanding Voting Interests and one of which
shall be appointed by the Principals. The initial Representatives are specified
in Schedule II.

                  (b) All decisions of the Management Committee shall be by
resolution duly adopted in accordance with the provisions of this Agreement. The
Management Committee may delegate such general or specific authority to the
Manager and the officers of the Company as it from time to time considers
desirable, and the Manager and the officers of the Company may exercise the
authority granted to them, subject to any restraints or limitations imposed by
the Management Committee and the provisions of Section 8.5 and any other express
provisions of this Agreement.

         8.2  Appointment and Removal of Representatives.

                  (a) The Chairman and Secretary of the Management Committee
shall be chosen by the Management Committee.

                  (b) Holders of a majority of the outstanding Voting Interests
may vote at any time to remove any of the Representatives previously appointed
by the holders of a majority of the outstanding Voting Interests, with or
without cause, and may replace any Representative so removed, by sending notice
of such removal and replacement to the other Members and the Principals. The
Principals may at any time remove the Representative appointed by them, with or
without cause, and may replace the Representative so removed, by sending notice
of such removal and replacement to the Members. No Representative shall be
removed from office, with or without cause, other than as provided in the
preceding two sentences.

                                      -40-
<PAGE>
 
                  (c) If any Representative is unwilling or unable to serve as
such or is removed from office, before the transaction of any other business by
the Management Committee, holders of a majority of the outstanding Voting
Interests, in the case of any Representative appointed by holders of a majority
of the outstanding Voting Interests, or the Principals, in the case of the
Representative appointed by the Principals, shall appoint a successor to such
Representative.

                  (d) No compensation of, or expenses incurred by, the
Representatives incident to their duties and responsibilities as such under this
Agreement shall be paid by, or charged to, the Company.

         8.3  Meetings of the Management Committee.

         The Management Committee shall hold one regular meeting each year at
such time and place as shall be determined by the Chairman of the Management
Committee. Special meetings of the Management Committee may be called at any
time by any Representative upon not less than three Business Days' prior notice
to the other Representatives, which may be waived by each Representative either
before or after the meeting. Except as otherwise determined by the Chairman of
the Management Committee, all special and regular meetings of the Management
Committee shall be held at the principal office of the Company.

         8.4  Procedural Matters.

                  (a) Each Representative shall have one vote in all matters
presented to the Management Committee for decision or approval. At all meetings
of the Management Committee, except as otherwise expressly provided for in this
Agreement, the affirmative vote of a majority of the Representatives, present at
such meeting in person or by proxy, shall be required for all actions and
decisions of the Management Committee. If a majority of the Representatives are
not present in person or represented by proxy at any meeting, the
Representatives present may adjourn the meeting from time to time, without
notice other than an announcement at the meeting, until a majority of the
Representatives shall be present or represented.

                  (b) Any notice of a special meeting of the Management
Committee shall state the purpose for which such meeting has been called.

                  (c) Each Representative entitled to vote at a meeting of the
Management Committee or to express consent to any action in writing without a
meeting or to express consent to any action pursuant to any other provision of
this Agreement may authorize another Representative or any individual reasonably
acceptable to the other Representatives to act for him by proxy. Any
Representative may designate another individual reasonably acceptable to the
other Representatives to act as the alternate of such Representative at any
meeting of the Management Committee.

                  (d) Any action required or permitted to be taken by the
Management Committee may be taken without a meeting if all Representatives
consent in writing to such action. Such consent shall have the same effect as a
vote of the Management Committee. Members of the 

                                      -41-
<PAGE>
 
Management Committee shall have the right to participate in a meeting of the
Management Committee by means of a conference telephone or similar
communications equipment by means of which all Representatives participating in
the meeting can hear each other and be heard, and such participation shall
constitute presence in person at the meeting.

                  (e) The Management Committee shall cause to be kept a book of
minutes of all of its meetings in which there shall be recorded the time and
place of each such meeting, whether regular or special, and if special, by whom
called, the notice thereof given, the names of those present, and the
proceedings thereof.

         8.5  Matters Requiring Approval by the Principals.

         Notwithstanding any provision in this Agreement to the contrary, and in
addition to any other consent or approval that may be required by the express
terms of this Agreement, without the consent of the Principals, which may be
withheld by the Principals in their sole discretion, the Company shall not, and
neither the Manager nor the Management Committee shall have any authority to
cause the Company to, or cause or permit any Subsidiary to:

                  (a) enter into any transaction between the Company or any
Subsidiary and either Member or any Affiliate of either Member, unless such
transaction is on commercially reasonable terms;

                  (b) except for a Membership Interest issued in accordance with
Section 2.1(d)(4)(A) of the Contribution Agreement, issue any Membership
Interest or any option, warrant, or other debt or equity interest convertible
into or evidencing the right to acquire (whether or not for additional
consideration) any Membership Interest, unless:

                           (i)      either (A) at least twenty-five percent of
the Membership Interests or other debt or equity interests so issued are issued
to Persons that are not Related Parties of Insight (for purposes of this Section
8.5(b), a "Related Party" of Insight means any Affiliate of Insight, any member,
partner, officer, director, shareholder, employee, or agent of Insight or of any
Affiliate of Insight, and any Person that has a material financial relationship
with Insight or any Affiliate of Insight), or (B) the Company has obtained and
delivered to Central and the Principals an opinion of an independent investment
banking firm of nationally recognized standing that the terms and conditions on
which such Membership Interests or other debt or equity interests are to be
issued are fair, from an economic standpoint, to the Company and the holders of
the outstanding Membership Interests; and

                           (ii) any of such Membership Interests or other debt
or equity interests that are issued to Persons that are Related Parties of
Insight are issued on the same terms and conditions as the Membership Interests
or other debt or equity interests that are issued to Persons that are not
Related Parties of Insight; and

                           (iii) the Company shall have afforded the Principals
or their designee (provided that such designee, if it is not Central, shall be
entirely owned, directly or indirectly, by

                                      -42-
<PAGE>
 
one or more of the Principals and shall be owned, at least in part, directly or
indirectly, by Dennis McGillicuddy) the opportunity to acquire a portion of the
Membership Interests or other debt or equity interests so issued (other than any
Membership Interests or other debt or equity interests that are issued to
Persons that are not Related Parties of Insight) equal to a fraction, the
numerator of which is the number of Units assigned to the Common Interests held
by Central or otherwise held directly or indirectly by the Principals
immediately prior to such issuance and the denominator of which is the sum of
the number of Units assigned to all Common Interests held by Insight and Related
Parties of Insight prior to such issuance plus the number of Units assigned to
the Common Interests held by Central or otherwise held directly or indirectly by
the Principals immediately prior to such issuance;

                  (c) sell or otherwise dispose of, or cause or permit any
Subsidiary to sell or otherwise dispose of, any assets of the Company or any
Subsidiary that were contributed to the Company by Central or any assets of the
Company or any Subsidiary the initial adjusted tax basis of which is determined,
in whole in part, with reference to the adjusted tax basis of the assets
contributed by Central, except upon the liquidation and dissolution of the
Company in accordance with Section 10 and except for:

                           (i)  sales and dispositions of assets that do not
involve the disposition of any of the Company's cable television subscribers;
and

                           (ii) any disposition of assets that does not,
together with all prior dispositions previously made by the Company, represent a
portion of the Company's business serving more than 1,000 cable television
subscribers in the aggregate;

                  (d) sell or otherwise dispose of, or cause or permit any
Subsidiary to sell or otherwise dispose of, any assets of the Company or any
Subsidiary if such sale or other disposition would trigger the right of any
holder of any of the Senior Debt or any of the Subordinated Debt to require that
any of such Senior Debt or Subordinated Debt be repaid, purchased, or redeemed;

                  (e) enter into any agreement restricting the ability of the
Company to make any distribution required to be made pursuant to Section
4.1(a)(i), Section 4.1(a)(ii), or Section 4.1(a)(iii) or to redeem the Preferred
B Interest to the extent required by Section 4.3;

                  (f)      liquidate or dissolve except in accordance with
Section 10; or

                  (g)      do any act in contravention of this Agreement, the
Certificate of Formation of the Company, or the Act.

         The parties acknowledge and agree that each provision of this Section
8.5 is intended to be a separate condition and that therefore, for example, a
sale or disposition described in Section 8.5(c) would require the consent of the
Principals under Section 8.5(c) even if such sale or other disposition did not
require the consent of the Principals under any other provision of this Section
8.5. The parties agree to negotiate in good faith and, if such negotiations are
successful, to enter into an amendment to this Agreement that would (a) permit
the Company to consummate transactions that 

                                      -43-
<PAGE>
 
are intended to qualify, in whole or in part, under Code Section 1031, so long
as, in the opinion of nationally-recognized tax counsel based on an appraisal
acceptable to the Principals, the aggregate federal, state, or local tax
liability of the Principals resulting from all such dispositions and any
dispositions made pursuant to Section 8.5(c)(ii) does not exceed $2,750,000, (b)
provide a means to allow the Principals to pay any federal, state, or local tax
liability in excess of $2,750,000 if any transaction that was intended to be
within the limitations in clause (a) ultimately generates a greater federal,
state, or local tax liability to the Principals than was originally
contemplated, (c) allocate any additional depreciation and amortization for tax
purposes and other economic factors resulting from the recognition of income or
gain in any transaction that was intended to qualify under Code Section 1031,
and (d) make additional changes to this Agreement consistent with the principles
underlying the amendments described in the foregoing clauses.

         8.6  Permitted Transactions.

                  (a) Other Businesses. Nothing in this Agreement shall limit
the ability of either Member, any partner, Affiliate, or agent of either Member,
or any Representative to engage in or possess an interest in other business
ventures of any nature or description, independently or with others, whether
currently existing or hereafter created and whether or not competitive with or
advanced by the business of the Company. Neither the Company nor the other
Member shall have any rights in or to the income or profits derived therefrom,
nor shall either Member have any obligation to the other Member with respect to
any such enterprise or related transaction. The foregoing provisions shall not
impair or otherwise affect any limitation to which either Member is or may be
subject with respect to his business activities under any other agreement
between the Company and such Member.

                  (b) Dealings with the Company. Subject to Section 8.5(a), the
Company may, in the discretion of the Management Committee, contract with any
Person (including either Member or any Person that is an Affiliate of either
Member or in which either Member may be interested) for the performance of any
services that may reasonably be required to carry on the business of the
Company, and any such Person dealing with the Company, whether as an independent
contractor, agent, employee, or otherwise, may receive from others or from the
Company profits, compensation, commissions, or other income incident to such
dealings.

         8.7  Other Management Matters.

                  (a) Central and the Shareholders as Affiliates of Insight. The
parties agree that each Shareholder shall be an Affiliate of Insight for
purposes of this Agreement so long as the management agreement between Insight
and such Shareholder remains in effect and that Central shall be an Affiliate of
Insight for purposes of this Agreement so long the management agreements between
Insight and Shareholders holding a majority of the outstanding shares of Central
remain in effect. Notwithstanding the foregoing or any other provision of this
Agreement, Insight shall not be in violation of any provision of this Agreement
restricting any action by its Affiliates with respect to any action taken by
Central or any Shareholder to the extent that such action was caused to be taken
by one or more of the Principals exercising authority reserved to the Principals
under the management agreements between Insight and Shareholders, and Insight
shall not be in violation of 

                                      -44-
<PAGE>
 
any provision of this Agreement requiring any action by its Affiliates with
respect to any action not taken by Central or any Shareholder to the extent that
such action was prevented from being taken by one or more of the Principals
exercising authority reserved to the Principals under the management agreements
between Insight and Shareholders.

                  (b) Programming and Other Discounts. Insight agrees to make
available to the Company the benefits of any currently existing programming or
equipment discounts or other similar beneficial arrangements that are available
to Insight Communications Company, L.P.

                            INTERESTS IN THE COMPANY

         9.1 Limitations on Transfers.

                  (a) Except as provided in Section 9.1(b), neither Member may
sell, assign, transfer, or otherwise dispose of, or pledge, hypothecate, or
otherwise encumber all or any part of its Membership Interest (any such action,
a "Transfer"), whether voluntarily, involuntarily, or by operation of law,
unless approved by the other Member and the Principals. Notwithstanding the
approval of the other Member and the Principals to any Transfer by a Member, the
rights of any Assignee shall be subject at all times to the limitations set
forth in Section 9.2.

                  (b) The restrictions of Section 9.1(a) shall not apply and no
consent of the other Member or the Principals shall be required for:

                           (i)      a Transfer to an Affiliate of the
transferring Member;

                           (ii)     a redemption of the Preferred A Interest or
the Preferred B Interest pursuant to Section 4.3;

                           (iii)    a Transfer pursuant to Section 9.7;

                           (iv)     a sale of all or part of the Common Interest
of Insight if Insight complies with Section 9.6(a);

                           (v)      a sale of all or part of the Common Interest
of Central in accordance with Section 9.6(a), Section 9.6(b), or Section 9.6(c);
or

                           (vi)     a sale of Insight's Membership Interest to a
Person designated by the Principals pursuant to Section 9.11.

         9.2  Assignee.

         If the provisions of this Section 9 have been complied with, an
Assignee shall be entitled to receive distributions of cash or other property,
and allocations of Net Profit and Net Loss and of items of income, deduction,
gain, loss, or credit, from the Company attributable to the assigned 

                                      -45-
<PAGE>
 
Membership Interests from and after the effective date of the assignment, and
shall have the right to receive a copy of the financial statements required
herein to be provided the Members, but an Assignee shall have no other rights of
a Member herein, such as rights to any other information, an accounting,
inspection of books or records, or voting as a Member on matters required by
law, unless and until such Assignee is admitted as a substitute Member pursuant
to the provisions of Section 9.3. The Company and the Manager shall be entitled
to treat the assignor as the absolute owner of the Membership Interests in all
respects, and shall incur no liability for distributions, allocations of Net
Profit or Net Loss, or transmittal of reports and notices required to be given
to Members that are made in good faith to the assignor until the effective date
of the assignment, or, in the case of the transmittal of reports (other than the
financial statements referred to above) or notices, until the Assignee is so
admitted as a substitute Member. The effective date of an assignment shall be
the first day of the calendar month following the month in which the Manager has
received an executed instrument of assignment in compliance with this Section 9
or the first day of a later month if specified in the executed instrument of
assignment. The Assignee shall be deemed an Assignee on the effective date, and
shall be only entitled to distributions and allocations of Net Profit and Net
Loss attributable to the period beginning on the effective date of assignment.
The Company shall attribute Net Profit and Net Loss to the period before the
effective date of assignment and to the period beginning on the effective date
of assignment by the interim closing of the Company books method set forth in
Treasury Regulation Section 1.706-1(c)(2)(ii). Each Assignee will inherit the
balance of the Capital Account, as of the effective date of assignment, of the
assignor with respect to the Membership Interests assigned.

         9.3  Substitute Members.

         Any Assignee of Insight's Membership Interest pursuant to Section 9.11
shall be automatically admitted as a substitute Member. Any other Assignee may
not become a substitute Member unless all of the following conditions are first
satisfied:

                  (a) a duly executed and acknowledged written instrument of
assignment shall have been filed with the Company, specifying the Membership
Interests being assigned and setting forth the intention of the assignor that
the Assignee succeed to the assignor's interest as a substitute Member;

                  (b) the assignor and Assignee shall have executed and
acknowledged any other instruments that the Principals, in the case of a
Transfer by Insight, or Insight, in the case of any other Transfer, deems
necessary or desirable for substitution, including the written acceptance and
adoption by the Assignee of the provisions of this Agreement and the assumption
by the Assignee of all obligations of the assignor under this Agreement
(including, in the case of a Transfer by Insight, the obligations of Insight
under Section 3.5);

                  (c) except in the case of an assignment permitted by Section
9.1(b), the Principals, in the case of a Transfer by Insight, or Insight, in the
case of any other Transfer, shall have consented in writing to the admission of
the Assignee as a substitute Member, the granting of which may be withheld by
the Principals or Insight, as applicable, in their or its sole and absolute
discretion; and

                                      -46-
<PAGE>
 
                  (d) the assignment to the Assignee shall have complied with
the other provisions of this Section 9.

         9.4  Other Consents and Requirements.
              
         Any Transfer must be in compliance with all requirements imposed by any
state securities administrator having jurisdiction over the Transfer and the
United States Securities and Exchange Commission and must not cause the Company
or any Subsidiary to be in violation of any cable television franchise, any
provision of the Communications Act of 1934, as amended, or any other law
subsequently enacted, or any rule, regulation, or policy of the Federal
Communications Commission promulgated thereunder restricting the ownership and
control of communications properties (including cable television systems,
television broadcast stations, radio broadcast stations, telephone companies,
and newspapers), including those relating to multiple ownership, cross-ownership
and cross-interest, as those terms are commonly understood in the communications
industry.

         9.5  Assignment Not In Compliance.

         Any Transfer in contravention of any of the provisions of this Section
9 (whether voluntarily, involuntarily or by operation of law) shall be void and
of no effect, and shall neither bind nor be recognized by the Company.

         9.6  Tag-Along and Drag-Along Rights.

                  (a) Tag-Along Rights. If Insight desires at any time to sell
to any other Person (the "Third-Party Purchaser") all or any part of any Common
Interest held by Insight, Insight shall send Central and the Principals a
written notice of the proposed sale and shall afford Central the opportunity to
sell to the Third-Party Purchaser, for the type of consideration provided in
Section 9.6(d), on terms equivalent as to purchase price per Unit (subject to
Section 9.6(g)) and otherwise identical (subject to Section 9.6(f)) to those
applicable to the sale of the Common Interest proposed to be sold by Insight,
that percentage of its Common Interest equal to a fraction, the numerator of
which is the number of Units assigned to the Common Interest proposed to be sold
by Insight and the denominator of which is the number of Units assigned to all
of the Common Interests of Insight. For purposes of this Section 9.6(a), Central
shall have been afforded the opportunity to sell its Common Interest if Central
and the Principals shall have received, at least thirty days prior to the sale
by Insight, the notice from Insight referred to in the first sentence of this
Section 9.6(a), specifying the material terms of the proposed sale, the purchase
price and other terms and conditions of payment, and the anticipated date on or
about which the proposed sale is to be made, and accompanied by an offer from
the Third-Party Purchaser to purchase Central's Common Interest on the terms
described in this Section 9.6(a). Central shall accept the offer to sell its
Common Interest pursuant to this Section 9.6(a) if the Principals so elect, and
Insight's notice to Central and the Principals pursuant to this Section 9.6(a)
shall specify the deadline before which the Principals must notify Insight of
their election that Central sell any of its Common Interest pursuant to this
Section 9.6(a), which deadline may not be before the later of (1) the fifteenth
day after the Principals' receipt 

                                      -47-
<PAGE>
 
of Insight's notice or (2) the fifth day after the amount of consideration
allocable to Insight's Common Interest is agreed to between Insight and the
Principals or otherwise determined pursuant to Section 9.6(e). Any purchase and
sale of any part of Central's Common Interest pursuant to this Section 9.6(a)
shall be conditioned on the consummation of the purchase and sale of Insight's
Common Interest to which this Section 9.6(a) applies.

                  (b) Drag-Along Rights. In connection with any sale by Insight
of all or any part of its Common Interests, Insight may elect to require that
Central sell (and, upon such election, Central shall be obligated to sell) to
the Third-Party Purchaser, for the type of consideration provided in Section
9.6(d), on terms equivalent as to purchase price per Unit (subject to Section
9.6(g)) and otherwise identical (subject to Section 9.6(f)) to those applicable
to the sale by Insight of its Common Interest, that percentage of its Common
Interest equal to a fraction, the numerator of which is the number of Units
assigned to the Common Interest to be sold by Insight and the denominator of
which is the number of Units assigned to all of the Common Interests of Insight.
Notwithstanding the foregoing, Insight's right to elect that Central sell all or
part of its Common Interest and Central's obligation to sell all or part of its
Common Interest shall be subject to any required consent or approval of the
holders of the Senior Debt or the holders of the Subordinated Debt and to any
liens securing the Senior Debt, the Subordinated Debt, or any other obligations
and liabilities arising under the Loan Documents. Any purchase and sale of all
or part of Central's Common Interest pursuant to this Section 9.6(b) shall be
conditioned on the consummation of the purchase and sale of Insight's Common
Interest to which this Section 9.6(b) applies.

                  (c)      Put and Call of Central's Common Interest.

                           (i)      Prior to the consummation of any transaction
or series of related transactions that would result in Insight ceasing to be
controlled, directly or indirectly, by one or more individuals who, on the date
of this Agreement, collectively control Insight (other than a transaction to
which Section 9.6(a) applies), Insight shall send Central and the Principals a
written notice setting forth the material terms of the proposed transaction and
setting forth the purchase price that would be paid for Central's Common
Interest if the Principals make an election pursuant to this Section 9.6(c), as
determined in accordance with Section 9.6(e). Within fifteen days after their
receipt of such notice, the Principals may elect, by delivering written notice
of their election to Insight, to require that Insight purchase all of Central's
Common Interest and that Central sell all of its Common Interest to Insight, for
the purchase price determined pursuant to Section 9.6(e) (subject to Section
9.6(g)) and otherwise on terms comparable (subject to Section 9.6(f)) to those
applicable to the transaction involving Insight to which this Section 9.6(c)
applies. Upon an election by the Principals pursuant to this Section 9.6(c),
Insight shall be obligated to purchase and Central shall be obligated to sell
all of Central's Common Interest. Insight's notice to Central and the Principals
pursuant to this Section 9.6(c)(i) shall specify the deadline before which the
Principals must notify Insight of their election to require that Central sell
its Common Interest pursuant to this Section 9.6(c), which deadline may not be
before the later of (A) the fifteenth day after the Principals' receipt of
Insight's notice or (B) the fifth day after the amount of consideration
allocable to Insight's Common Interest is agreed to between Insight and the
Principals or otherwise determined pursuant to Section 9.6(e).

                           (ii)     In connection with the consummation of any
transaction or series of related transactions that would result in Insight
ceasing to be controlled, directly or indirectly, by one or more individuals
who, on the date of this Agreement, collectively control Insight (other than a
transaction to which Section 9.6(a) applies), Insight may elect to require that
Central sell (and, upon such election, Central shall be obligated to sell) to
Insight all of Central's Common Interest for the purchase price determined
pursuant to Section 9.6(e) (subject to Section 9.6(g)) and otherwise on terms
comparable (subject to Section 9.6(f)) to those applicable to the transaction
involving Insight to which this Section 9.6(c) applies. Notwithstanding the
foregoing, Insight's right to elect that Central sell its Common Interest and
Central's obligation to sell its Common Interest shall be subject to any
required consent or approval of the holders of the Senior Debt or the holders of
the Subordinated Debt and to any liens securing the Senior Debt, the
Subordinated Debt, or any other obligations and liabilities arising under the
Loan Documents.

                           (iii) Any purchase and sale of Central's Common
Interest pursuant to this Section 9.6(c) shall be conditioned on the
consummation of the transaction involving Insight to which this Section 9.6(c)
applies.

                           (iv)  The closing of the purchase and sale of
Central's Common Interest pursuant to this Section 9.6(c) shall occur
concurrently with the closing of the transaction that results in Insight ceasing
to be controlled, directly or indirectly, by one or more individuals who, on the
date of this Agreement, collectively control Insight. At the closing of the
purchase and sale of Central's Common Interest pursuant to this Section 9.6(c),
Insight shall pay or cause to be paid to Central the purchase price in the form
provided in Section 9.6(d), and Central will convey to Insight all of its Common
Interest free and clear of all claims, liabilities, security interests,
mortgages, liens, pledges, conditions, charges, and encumbrances of any nature
whatsoever, other than the rights granted to other parties under this Agreement
and liens securing the Senior Debt, the Subordinated Debt, and any other
obligations and liabilities arising under the Loan Documents.

                  (d)      Consideration for Purchase of Central's Common
Interest; Tax Loans.

                           (i)      In case of a sale of all or part of
Central's Common Interest pursuant to Section 9.6(a), Section 9.6(b), or Section
9.6(c), the purchase price shall be paid through the delivery to Central of
property (including cash) of the same kind, and in the same proportions, as that
received by Insight or any direct or indirect owner of Insight in connection
with the transaction that triggered the right or obligation of Central to sell
all or part of Central's Common Interest pursuant to Section 9.6(a), Section
9.6(b), or Section 9.6(c). For purposes of this Section 9.6(d)(i) and Section
9.6(e), any liabilities assumed by the purchaser as part of the transaction that
triggered the right or obligation of Central to sell all or part of Central's
Common Interest pursuant to Section 9.6(a), Section 9.6(b), or Section 9.6(c)
(whether assumed directly or indirectly as part of the acquisition of the
outstanding equity interests in any entity, other than liabilities of the
Company) shall be treated as cash received by the selling Person. Any property
other than cash received by Central pursuant to this Section 9.6(d)(i) shall
have the same rights as to liquidity and marketability, including, in the case
of securities, registration rights, as the property received by Insight or any
direct or indirect owner of Insight.

                                      -49-
<PAGE>
 
                           (ii) To the extent that (A) the amount of cash plus
the fair market value of any marketable securities received by Central as
consideration for the sale of Central's Common Interest pursuant to Section
9.6(b) or Section 9.6(c)(ii), is less than the tax liabilities of Central, the
Principals, and their respective Affiliates resulting from the sale of Central's
Common Interest, and (B) Central (or any Person, including any Principal, to
whom the consideration for the sale of Central's Common Interest is distributed
by Central and the Shareholders) is unable, after using commercially reasonable
efforts, to borrow the amount of such tax liabilities on the terms described in
clauses (1), (2), and (3) of the last sentence of this Section 9.6(d)(ii) with
respect to loans from Insight and at an interest rate not materially higher than
that described in clause (4) of the last sentence of this Section 9.6(d)(ii)
with respect to loans from Insight, then Insight agrees to lend to Central the
amount of such tax liabilities (less any amount that Central was able to borrow
from a lender other than Insight). Any such loan from Insight shall (1) be non-
recourse to the borrower, (2) secured only by any consideration received by
Central as consideration for the sale of its Common Interest, other than cash,
marketable securities, and any security given to secure Central's borrowings
pursuant to this Section 9.6(d)(ii) from a lender other than Insight, (3) not
require that it be repaid prior to such time as Central (or any successor) is
able to liquidate the consideration (other than cash and marketable securities)
received for the sale of Central's Common Interest, and (4) bear interest at the
weighted average cost of funds of Insight Communications Company, L.P. and its
subsidiaries for their secured debt or, if Insight Communications Company, L.P.
and its subsidiaries have no secured debt, for their senior debt.

                  (e) Allocation of Consideration. If Insight (i) sends a notice
to Central and the Principals pursuant to Section 9.6(a) or makes an election
pursuant to Section 9.6(b) with respect to any proposed sale to a Third-Party
Purchaser that contemplates a sale of all or part of Insight's Common Interest
in conjunction with other assets or (ii) sends a notice to Central pursuant to
Section 9.6(c)(i), Insight and the Principals shall cause the amount of
consideration proposed to be paid in any such transaction that is allocable to
Insight's Common Interest to be determined. Unless Insight and the Principals
otherwise agree (either as to the applicable value or as to an alternative
method of determining such value, including the use of a single appraiser agreed
upon between Insight and the Principals), the amount of consideration allocable
to all or part of Insight's Common Interest shall be determined as provided
below in this Section 9.6(e):

                           (i)      Insight shall deliver to the Principals a
notice stating that Insight intends to send a notice or make an election to
which this Section 9.6(e) applies and identifying an appraiser ("Insight's
Appraiser") who has been retained by the Company to allocate the total
consideration proposed to be paid in such transaction pursuant to this Section
9.6(e). Within ten business days after their receipt of Insight's notice
pursuant to the preceding sentence, the Principals shall send a notice to
Insight identifying a second appraiser ("Central's Appraiser") who shall also be
retained by the Company to make such allocation pursuant to this Section 9.6(e).

                           (ii)     Insight's Appraiser and Central's Appraiser
shall submit their independent determinations of the amount of consideration
allocable to the portion of Insight's Common Interest proposed to be transferred
(directly or indirectly) within thirty days after the date on which Central's
Appraiser is retained. If the respective determinations of Insight's Appraiser
and Central's Appraiser vary by less than ten percent of the higher
determination, the amount of 

                                      -50-
<PAGE>
 
consideration allocable to the portion of Insight's Common Interest proposed to
be transferred (directly or indirectly) shall be the average of the two
determinations.

                           (iii) If the respective determinations of Insight's
Appraiser and Central's Appraiser vary by ten percent or more of the higher
determination, the two appraisers shall promptly designate a third appraiser
(the "Third Appraiser"), who shall also be retained by the Company to make an
allocation or conduct an appraisal pursuant to this Section 9.6(e). Insight's
Appraiser and Central's Appraiser shall be instructed not to, and neither Member
nor any Affiliate of either Member shall, provide any information to the Third
Appraiser as to the determinations of Insight's Appraiser and Central's
Appraiser or otherwise influence the Third Appraiser's determination in any way.
The Third Appraiser shall submit its determination of the amount of
consideration allocable to the portion of Insight's Common Interest proposed to
be transferred (directly or indirectly) within thirty days after the date on
which the Third Appraiser is retained. If a Third Appraiser is retained, the
amount of consideration allocable to the portion of Insight's Common Interest
proposed to be transferred (directly or indirectly) shall equal the average of
the two closest of the three determinations, except that, if the difference
between the highest and middle determinations is no more than 105% and no less
than 95% of the difference between the middle and lowest determinations, then
the amount of consideration allocable to the portion of Insight's Common
Interest proposed to be transferred (directly or indirectly) shall equal the
middle determination.

                           (iv)    Any appraiser retained pursuant to this
Section 9.6(e) shall be nationally recognized as being qualified and experienced
in the appraisal of cable television systems, assets comparable to Insight's
Common Interest, any other assets proposed to be sold by Insight, and any other
assets owned by relevant Persons owning direct or indirect ownership interests
in Insight, each as applicable, and shall not be an Affiliate of either Member.
All fees and expenses of any appraiser retained pursuant to this Section 9.6(e)
shall be paid by the Company.

                           (v)      In determining the fair market value of any
asset, to the extent relevant to its allocation of consideration to Insight's
Common Interest, each appraiser retained pursuant to this Section 9.6(e) shall
(A) assume that the fair market value of the applicable asset is the price at
which the asset would change hands between a willing buyer and a willing seller,
neither being under any compulsion to buy or sell and each having reasonable
knowledge of all relevant facts; (B) assume that the applicable asset would be
sold for cash; (C) use valuation techniques then prevailing in the relevant
industry; (D) assume that any assets constituting a going concern would be sold,
in the aggregate, as a going concern, in a single transaction; (E) assume that
the value of Insight's Common Interest includes the value of any right of
Insight or any Affiliate of Insight to control the Company, regardless whether
such right inures in any other Membership Interest or arises under any other
agreement.

                           (vi)    For purposes of Section 9.6(a), Section
9.6(b), or Section 9.6(c), the purchase price to be paid for any portion of
Insight's Common Interest proposed to be transferred (directly or indirectly)
shall be the amount of the total consideration that is allocated to such portion
of Insight's Common Interest pursuant to this Section 9.6(e) (subject to Section
9.6(g)).

                  (f)      Absence of Representations.

                           (i)      In connection with any sale by Central
pursuant to Section 9.6(a), Section 9.6(b), or Section 9.6(c), neither Central
nor any Principal shall be required to (i) make any representation or warranty
to the Third-Party Purchaser other than (A) a representation and warranty to the
effect that, at the closing of the purchase and sale of Central's Common
Interest, Central will hold its Common Interest free and clear of all claims,
liabilities, security interests, mortgages, liens, pledges, conditions, charges,
and encumbrances of any nature whatsoever, other than the rights granted to
other parties under this Agreement and liens securing the Senior Debt, the
Subordinated Debt, and any other obligations and liabilities arising under the
Loan Documents, and (B) customary, non-operational representations and
warranties (such as those relating to Central's legal existence and corporate
authority, due authorization of the purchase and sale agreement, and the absence
of legal impediments to the consummation of the sale that relate specifically to
Central), (ii) make any covenant except as to the delivery to the Third-Party
Purchaser of Central's Common Interest, or (iii) indemnify the Third-Party
Purchaser for any liability other than damages resulting from a breach of the
representations described in this Section 9.6(f).

                           (ii)     Notwithstanding the foregoing provisions of
this Section 9.6(f), but subject to Section 9.6(f)(iii), in connection with any
sale by Central pursuant to Section 9.6(a) or Section 9.6(b), Central shall be
responsible for Central's proportionate share (calculated per Unit) of any
purchase price reduction or indemnity obligation of Insight that is attributable
to:

                                    (A)     a breach of any customary
representation, warranty, or covenant relating to the business, operations, or
liabilities of the Company (but not any representation, warranty, or covenant
that relates specifically to Insight, such as those relating to Insight's legal
existence and authority, due authorization of the purchase and sale agreement,
and the absence of legal impediments to the consummation of the sale by
Insight); and

                                    (B) any provision in the purchase and sale
agreements with respect to the Common Interests that requires customary deferred
adjustments to the purchase price (such as those relating to net working
capital, cash flow, and numbers of subscribers) until a reasonable period after
the closing of the purchase and sale of the Common Interest pursuant to Section
9.6(a) or Section 9.6(b).

                           (iii) Under no circumstances shall Central be
required to reimburse Insight for any part of any special, incidental,
consequential, exemplary, or punitive damages that may be payable to any Third-
Party Purchaser as a result of any breach by Insight of any representation or
warranty in connection with the sale of Common Interests pursuant to Section
9.6(a) or Section 9.6(b).

                  (g)      Reallocation of Purchase Price.

                           (i)      Subject to Section 9.6(g)(iv), in connection
with any sale to a Third-Party Purchaser pursuant to Section 9.6(a) or Section
9.6(b) of all or a majority of the outstanding Common Interests that includes a
sale of all or a majority of the Common Interest held by Insight and the same
percentage of the Common Interest held by Central, if Insight has received an
offer described in Section 9.6(g)(iii)(B) and, before giving effect to this
Section 9.6(g), the consideration that would be paid to Insight per Unit for its
Common Interest would be less than the Unit Liquidation Amount, then the total
consideration to be paid by the Third-Party Purchaser to Insight and Central for
their Common Interest shall be reallocated so that:

                                    (A)     the amount paid to Insight for its
Common Interest, in the aggregate, shall equal the lesser of (1) the product of
the Unit Liquidation Amount times the number of Units assigned to the Common
Interest being sold by Insight and (2) the total consideration to be paid by the
Third-Party Purchaser to Insight and Central for their Common Interests; and

                                    (B)     the amount paid to Central for its
Common Interest, in the aggregate, shall equal the amount, if any, by which the
total consideration to be paid by the Third-Party Purchaser to Insight and
Central for their Common Interests exceeds the amount payable to Insight
pursuant to Section 9.6(g)(i)(A).

                           (ii)     Subject to Section 9.6(g)(iv), in connection
with any transaction described in Section 9.6(c), if Insight has received an
offer described in Section 9.6(g)(iii)(B) and the amount of consideration that
is allocated to Insight's Common Interest pursuant to Section 9.6(e) is less
than the Unit Liquidation Amount, then the purchase price to be paid for
Central's Common Interest shall be reduced by the lesser of (A) one-half of the
amount by which the amount of consideration that is allocated to Insight's
Common Interest pursuant to Section 9.6(e) is less than the Unit Liquidation
Amount, and (B) the purchase price to be paid for Central's Common Interest
before giving effect to this Section 9.6(g).

                           (iii)    For purposes of this Section 9.6(g),

                                    (A)     the "Unit Liquidation Amount" means
the amount that would have been distributed to Insight upon dissolution and
liquidation of the Company with respect to its Common Interest, per Unit, if (1)
the assets of the Company had been sold for the Offered Asset Purchase Price,
(2) Net Profit and Net Loss and items specially allocated in accordance with
Section 5.2, including any gain or loss resulting from the sale described in
clause (1), were allocated in accordance with Section 5, (3) the Company paid
its accrued, but unpaid, liabilities, other than liabilities that would have
been assumed by the purchaser in connection with the sale described in clause
(1), and (4) the Company distributed the remaining proceeds received by it (net
of reserves for contingent or unknown liabilities and any transaction costs that
would have been incurred in connection with such sale) to the Members in
liquidation; and

                                      -53-
<PAGE>
 
                                    (B)   the "Offered Asset Purchase Price"
means the highest purchase price offered to be paid by any Person that is not an
Affiliate of Insight for all the assets of the Company in a bona fide written
offer where (1) all terms and conditions of such offer with respect to
representations, warranties, covenants, indemnities, adjustments, closing
conditions, and other relevant non-price matters are customary, (2) the offeror
was legally qualified and financially capable (taking into account reasonable
expectations of financing availability) to purchase the assets of the Company
and, at the time the offer was made, there were no significant risks that the
offeror would be unable to close the purchase of the assets of the Company on
the offered terms, and (3) not more than thirty days before the execution of a
binding agreement for the transfer (directly or indirectly) of all of Insight's
Common Interest to which this Section 9.6(g) would apply, Insight sought the
consent of the Principals pursuant to Section 8.5(c) and, if applicable, Section
8.5(d) to a sale of all the assets of the Company to the Person making such
offer, on the terms described in such offer, and the Principals declined to
consent to such sale; provided, however, that if the terms and conditions of any
such offer with respect to relevant non-price matters are less favorable to the
Company, taken as a whole, than the terms and conditions of the sale of the
Common Interests to the Third-Party Purchaser, so as to affect value, then the
amount of the purchase price offered to be paid in such offer shall be reduced
by an appropriate amount to reflect the differences in such terms and
conditions, as agreed to between Insight and the Principals or, if they fail to
agree on the amount, as determined by an independent investment banking firm of
nationally recognized standing that is agreed to between Insight and the
Principals, or if they fail to agree on such investment banking firm, as agreed
to by an independent investment banking firm of nationally recognized standing
selected by Insight and an independent investment banking firm of nationally
recognized standing selected by the Principals.

                           (iv) This Section 9.6(g) shall not apply to any sale
of Common Interests occurring prior to the second anniversary of the Closing
Date or any transaction described in Section 9.6(c) occurring prior to the
second anniversary of the Closing Date.

         9.7  Pledge and Assignment of Interest.

         Central may pledge its Membership Interest only for the purposes of
securing the Senior Debt, the Subordinated Debt, and any other obligations and
liabilities arising under the Loan Documents. Insight may pledge its Membership
Interest only for the purposes of securing obligations of Insight Communications
Company, L.P. and its subsidiaries under its senior bank credit agreement, and
every subsequent amendment, modification, restructuring, extension, renewal, or
consolidation of such obligations, and any obligation incurred in refinancing or
replacement of or substitution for such obligations. Notwithstanding any
provision of this Agreement to the contrary, any Person to which Central or
Insight pledges its Membership Interest pursuant to this Section 9.7 (each, a
"Secured Party") may exercise all rights and remedies incident to the pledge of
such Membership Interest, which may include authority for the Secured Party
(without dissolving the Company unless dissolution is required by law):

                  (a) to cause the pledged Membership Interest to be assigned in
whole or in part on one or more occasions to one or more Persons (which may
include the Secured Party); provided, 

                                      -54-
<PAGE>
 
however, that any Transfer of Insight's Common Interest upon the exercise of any
rights or remedies incident to any pledge thereof shall be conditioned on
Insight's compliance with Section 9.6(a);

                  (b) to cause any assignee of the pledged Membership Interest
to be admitted as a Member having the interest so assigned;

                  (c) to cause the holder of the pledged Membership Interest to
resign as a Member once all of its Membership Interest has been assigned; and

                  (d) to cause one or more amended Certificates of Formation to
be filed with respect to the Company.

         9.8  Condition on Change in Control of the Company.

         Prior to the consummation of any transaction or series of related
transactions by Insight or any of its Affiliates, including any Transfer by
Insight of all or any part of its Membership Interest, that would trigger the
right of any holder of any of the Senior Debt or any of the Subordinated Debt to
require that such Senior Debt or Subordinated Debt be repaid, purchased, or
redeemed, Insight or, in the case of a Transfer, Insight or its Assignee shall:

                  (a) agree to purchase such Senior Debt or Subordinated Debt
from the holder thereof in the event the holder elects to require that such
Senior Debt or Subordinated Debt be repaid, purchased, or redeemed, and, upon
such purchase, Insight or its Assignee shall waive any right to require that
such Senior Debt or Subordinated Debt be repaid, purchased, or redeemed, or

                  (b) obtain an irrevocable, binding agreement of the holder of
such Senior Debt or Subordinated Debt not to require that such Senior Debt or
Subordinated Debt be repaid, purchased, or redeemed upon the consummation of
such Transfer.

         9.9  Substitution of Parent Undertaking.

         Prior to the consummation of any transaction or series of related
transactions, including any Transfer, that would result in Insight ceasing to be
controlled, directly or indirectly, by one or more individuals who, on the date
of this Agreement, collectively control Insight, Insight shall cause the Person
that, after giving effect to such transaction, would be the ultimate parent
entity (as determined in accordance with the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, and the rules and regulations promulgated
thereunder) of Insight, or such other Person reasonably acceptable to the
Principals, to execute and deliver to Central and the Principals an agreement,
substantially in the form of the parent undertaking executed and delivered by
Insight Communications Company, L.P. in connection with the execution and
delivery of this Agreement.

         9.10  Continuing Rights and Privileges.

         Notwithstanding the sale or other disposition by Central of all of its
Common Interest in accordance with this Agreement, Central shall continue to be
a Member of the Company so long as it continues to hold the Preferred A Interest
or the Preferred B Interest and shall have the rights and privileges specified
in this Agreement as pertaining to the Preferred A Interest or the Preferred B
Interest or specified in this Agreement as rights and privileges of Central.

         9.11 Insight's Right to Put Its Interest.

         Insight may elect at any time, by delivering written notice of its
election to Central and the Principals, to require that a Person designated by
the Principals purchase all of Insight's Membership Interest, for one dollar
(plus the Tax Amount that would be distributable to Insight on the date of the
next scheduled April Distribution after the closing of such purchase, calculated
as if the Company's Fiscal Year ended on the closing of such purchase). Upon an
election by Insight pursuant to this Section 9.11, the Principals shall be
obligated to cause a Person designated by the Principals to purchase and Insight
shall be obligated to sell all of Insight's Membership Interest. Insight's right
to make an election pursuant to this Section 9.11, and any purchase and sale of
Insight's Membership Interest pursuant to this Section 9.11, shall be subject to
the following provisions:

                  (a) At the closing of the purchase and sale of Insight's
Membership Interest pursuant to this Section 9.11, the Person designated by the
Principals shall pay to Insight one dollar and shall assign to Insight its right
to receive that portion of the next April Distribution after the closing equal
to the balance of the purchase price for Insight's Membership Interest, and
Insight will convey to the Person designated by the Principals all of its
Membership Interest free and clear of all claims, liabilities, security
interests, mortgages, liens, pledges, conditions, charges, and encumbrances of
any nature whatsoever, other than the rights granted to other parties under this
Agreement. The Company shall pay to Insight that portion of the next April
Distribution after the closing that was assigned to Insight, which payment shall
be considered payment by the Person designated by the Principals of the balance
of the purchase price for Insight's Membership Interest.

                  (b) The closing of the purchase and sale of Insight's
Membership Interest pursuant to this Section 9.11 shall occur on a date to be
specified by the Principals that is within 180 days after the Principals'
receipt of Insight's election pursuant to this Section 9.11, subject to the
receipt of all necessary governmental approvals and other material third-party
consents.

                  (c) Each of the management agreements between Insight and the
Shareholders shall terminate automatically upon the closing of the purchase and
sale of Insight's Membership Interest pursuant to this Section 9.11.

         9.12  Treatment of Certain Membership Interests.

         Any Membership Interests purchased by the Principals or their designee,
if it is not Central, pursuant to Section 8.5(b)(iii) shall be treated as if
such Membership Interests were owned by Central for purposes of this Section 9
(which includes Insight's right to require that such Membership 

                                      -56-
<PAGE>
 
Interests be sold under certain circumstances pursuant to Section 9.6(b) or
Section 9.6(c) and the Principals' right to require that such Membership
Interests be purchased under certain circumstances pursuant to Section 9.6(a) or
Section 9.6(c), in each case on the same terms as would be applicable to
Membership Interests owned by Central).

                 SECTION 10. DISSOLUTION AND TERMINATION OF THE

                                    COMPANY

         10.1 Events of Dissolution.

         The Company shall be dissolved upon the happening of any of the
following events:

                  (a)      December 31, 2058;

                  (b)      if the Principals consent to the resignation of
Insight as Manager pursuant to Section 6.2(a) but the Members and the Principals
do not elect to continue the Company thereafter in accordance with the
provisions of Section 6.2(a);

                  (c)      upon agreement of Insight and the Principals;

                  (d)      upon the affirmative vote of holders of a majority of
the outstanding Voting Interests; provided, however, that the holders of the
outstanding Voting Interests may not vote to dissolve the Company at any time
prior to the earlier of (1) the death of the last to die of Barry Silverstein,
Dennis McGillicuddy, and D. Stevens McVoy, or (2) the receipt by the Principals
of an opinion of their legal counsel that the dissolution and liquidation of the
Company would not, in its opinion, increase by more than a de minimis amount the
likelihood of adverse tax consequences to the Principals (other than adverse tax
consequences that are incurred after the triggering of all adverse tax
consequences to the Principals relating to the Senior Debt, the Subordinated
Debt, and the holding of the Preferred A Interest and the Preferred B Interest);

                  (e)      upon the sale of all or substantially all of the
assets of the Company in a manner permitted by this Agreement;

                  (f)      the termination of the Contribution Agreement in
accordance with its terms prior to the Closing; or

                  (g)      subject to any provision of this Agreement that
limits or prevents dissolution, the happening of any event that, under
applicable law, causes the dissolution of a limited liability company.

         10.2  Liquidation.

                  (a)      Upon dissolution of the Company for any reason, the
Company shall immediately commence to wind up its affairs. A reasonable period
of time shall be allowed for the orderly termination of the Company business,
discharge of its liabilities, and distribution or 

                                      -57-
<PAGE>
 
liquidation of the remaining assets so as to enable the Company to minimize the
normal losses attendant to the liquidation process.

                  (b)      Liquidation of the assets of the Company shall be
managed on behalf of the Company by the "Liquidator," which shall be (i) if
Insight wrongfully caused the dissolution of the Company, a liquidating trustee
selected by the Principals, and (ii) in all other events, Insight or a
liquidating trustee selected by Insight. The Liquidator shall be responsible for
soliciting offers to purchase the entirety of the Company's assets (including
equity interests in other Persons) or portions or clusters of assets of the
Company.

                  (c)      The Liquidator shall cause a full accounting of the
assets and liabilities of the Company to be taken and a statement thereof to be
furnished to each Member and each Principal within thirty days after the
distribution of all of the assets of the Company.

                  (d)      The property and assets of the Company and the
proceeds from the liquidation thereof shall be applied in the following order of
priority:

                           (i)      first, to payment of the debts and
liabilities of the Company, in the order of priority provided by law (including
any loans by either Member to the Company) and payment of the expenses of
liquidation;

                           (ii)     second, to setting up of such reserves as
the Liquidator may deem reasonably necessary for any contingent or unforeseen
liabilities or obligations of the Company or any obligation or liability not
then due and payable; provided, however, that any such reserve shall be paid
over by the Liquidator into a Company account or a liquidating trust account
established for such purpose, to be held in such account for the purpose of
disbursing such reserves in payment of such liabilities, and, at the expiration
of such holdback period as the Liquidator shall deem advisable, to distribute
the balance thereafter remaining in the manner hereinafter provided; and

                           (iii)     finally, remaining proceeds shall be
distributed to the Members as follows:

                                    (A)     First, if the Preferred A Interest
is then outstanding, to the holder of the Preferred A Interest in an amount
equal to the sum of (x) the amount of any distributions that were required to be
made pursuant to Section 4.1(a)(i) but were not made (including any increase to
such amount pursuant to Section 4.1(b)(i)), plus (y) a pro rata portion of the
Guaranteed Payment Amount, based on the ratio of the number of days between the
immediately preceding Guaranteed Payment Date and the date on which the
distribution is made pursuant to this Section 10.2(d)(iii)(A) to the number of
days between the immediately preceding Guaranteed Payment Date and the next
following Guaranteed Payment Date, computed on the basis of a 360-day year of
twelve 30-day months;

                                    (B)     Second, if the Preferred A Interest
is then outstanding, to the holder of the Preferred A Interest in an amount
equal to the sum of (x) the Preferred A Capital Amount, plus (y) the amount of
any distributions that were required to be made pursuant to Section

                                      -58-
<PAGE>
 
4.1(a)(ii) but were not made (including any increase to such amount pursuant to
Section 4.1(b)(ii)), plus (z) the amount by which the Preferred A Preference
Amount exceeds the amount described in clause (y) of Section 10.2(d)(iii)(A);

                                    (C)     Third, if the Preferred B Interest
is then outstanding, to the holder of the Preferred B Interest in an amount
equal to the sum of (x) the Preferred B Capital Amount, plus (y) the amount of
any distributions that were required to be made pursuant to Section 4.1(a)(iii)
but were not made (including any increase to such amount pursuant to Section
4.1(b)(iii)), plus (z) the Preferred B Preference Amount;

                                    (D)     Fourth, to the Manager in an amount
equal to the sum of (x) the amount of any distributions that were required to be
made pursuant to Section 4.1(a)(v) but were not made (including any increase to
such amount pursuant to Section 4.1(b)(iv)), plus (y) the Management Return;

                                    (E)     Thereafter, pro rata to the Members
in proportion to their remaining positive Capital Account balances, after
reducing the Members' Capital Account balances to take into account
distributions pursuant to the foregoing paragraphs of this Section 10.2(d)(iii).

The distributions pursuant to this Section 10.2(d)(iii) shall, to the extent
possible, be made prior to the later of the end of the Fiscal Year in which the
dissolution occurs or the ninetieth day after the date of dissolution, or such
other time period which may be permitted under Treasury Regulations Section
1.704-1(b)(2)(ii)(b).

         10.3  Distribution in Kind.

         The Company shall not distribute any non-cash asset to either Member
without the consent of each Member and the Principals, except that, upon
liquidation of the Company, the Company may distribute identical assets (such as
shares of stock or other securities) to the Members pro rata pursuant to Section
10.2(d)(iii)(E). The amount distributed and charged to the Capital Account of
each Member receiving any non-cash asset shall be the fair market value of such
asset, as agreed to by the Members and the Principals (net of any liability
secured by such asset that such Member assumes or takes subject to). Gain or
loss on the disposition of any asset distributed in kind to one or more Members
shall be determined as if such asset were sold for its fair market value, as
agreed to by the Members and the Principals, and such gain or loss shall then be
allocated pursuant to Section 5.

         10.4  No Action for Dissolution.

         The Members acknowledge that irreparable damage would be done to the
goodwill and reputation of the Company if either Member should bring an action
in court to dissolve the Company under circumstances where dissolution is not
required by Section 10.1. This Agreement has been drawn carefully to provide
fair treatment of all parties and equitable payment in liquidation of the
Membership Interests of both Members. Accordingly, except where liquidation and
dissolution are required by Section 10.1, each Member hereby waives and
renounces its right to initiate legal action 

                                      -59-
<PAGE>
 
to seek dissolution or to seek the appointment of a receiver or trustee to
liquidate the Company or to seek partition of any assets of the Company.

         10.5  No Further Claim.

         Upon dissolution, each Member shall look solely to the assets of the
Company for the return of its investment, and if the property of the Company
remaining after payment or discharge of the debts and liabilities of the
Company, including debts and liabilities owed to one or more of the Members, is
insufficient to return the aggregate capital contributions of a Member, neither
Member shall have any recourse against the other Member.

                          SECTION 11. INDEMNIFICATION

         11.1 General.

         The Company shall indemnify, defend, and hold harmless each Member and
its members, partners, officers, directors, shareholders, employees, and agents,
the employees, officers, and agents of the Company, the Principals, and the
Representatives (all indemnified persons being referred to as "Indemnified
Persons" for purposes of this Section 11.1), from any liability, loss, or damage
incurred by the Indemnified Person by reason of any act performed or omitted to
be performed by the Indemnified Person in connection with the business of the
Company (including, in the case of Insight, any such act in connection with the
management of the Shareholders pursuant to the management agreements between the
Shareholders and Insight, or arising by reason of Insight's status as manager of
the Shareholders), including costs and attorneys' fees (which attorneys' fees
may be paid as incurred) and any amounts expended in the settlement of any
claims of liability, loss, or damage; provided, however, that, if the liability,
loss, damage, or claim arises out of any action or inaction of an Indemnified
Person, indemnification under this Section 11.1 shall not be available if the
action or inaction constituted fraud, gross negligence, breach of fiduciary duty
(which shall not be construed to encompass mistakes in judgment or any breach of
any Indemnified Person's duty of care that did not constitute gross negligence),
willful misconduct, or a breach of this Agreement by the Indemnified Person; and
provided, further, however, that indemnification under this Section 11.1 shall
be recoverable only from the assets of the Company and not from any assets of
the Members. The Company may pay for insurance covering liability of the
Indemnified Persons for negligence in operation of the Company's affairs.

         11.2  Exculpation.

         No Indemnified Person shall be liable, in damages or otherwise, to the
Company or to either Member for any loss that arises out of any act performed or
omitted to be performed by it or him pursuant to the authority granted by this
Agreement unless the conduct of the Indemnified Person constituted fraud, gross
negligence, breach of fiduciary duty (which shall not be construed to encompass
mistakes in judgment or any breach of any Indemnified Person's duty of care that
did not constitute gross negligence), willful misconduct, or a breach of this
Agreement by such Indemnified Person.

         11.3  Persons Entitled to Indemnity.

         Any Person who is within the definition of "Indemnified Person" at the
time of any action or inaction in connection with the business of the Company
shall be entitled to the benefits of Section 11.1 as an "Indemnified Person"
with respect thereto, regardless of whether such Person continues to be within
the definition of "Indemnified Person" at the time of his or its claim for
indemnification or exculpation hereunder.

                  SECTION 12. BOOKS, RECORDS, ACCOUNTING, AND

shall promptly deliver to the requesting Member or Principal, at the expense of
the Company, a copy of the information required to be maintained by Section 12.1
except for Section 12.1(e).

                  (b) Each Member and each Principal, or its duly authorized
representative, has the right, upon reasonable request, to inspect and copy

                  (a) The Company shall cause to be prepared for each Member and
each Principal at least annually, at Company expense, audited financial

Company and the Subsidiaries in accordance with generally accepted accounting
principles, along with supplemental information for the Company and each

                           (i)      the Company shall distribute to each Member
and each Principal a statement setting forth the net income or loss of the

     In connection with the sale of the Securities, the Companies have prepared
a preliminary offering memorandum dated July 29, 1998 and a final offering

(as defined in Section 3 below) contained or contains any untrue statement of a
material fact or omitted or omits to state a material fact necessary to make the

upon and in conformity with information relating to the Initial Purchaser
furnished to the Companies or the Guarantor in writing by the Initial Purchaser
expressly for use in the Memorandum or any amendment or supplement thereto.

        (ii)   As of the Closing Date, the Companies will have the authorized,

validly issued, are fully paid and nonassessable and were not issued in
violation of any preemptive or similar rights; except as set forth in the
Memorandum, all of the outstanding ownership interests in the Guarantor are,
and as of the Closing Date will be, owned, directly or indirectly, by Coaxial

limited liability company, partnership or corporation, as the case may be, in
good standing in all other jurisdictions where the ownership or leasing of its
properties or the conduct of its business requires such qualification, except
where the failure to be so qualified would not, individually or in the
aggregate, have a material adverse effect on the general affairs, management,
business, condition (financial or otherwise), prospects or results of operations
of the Companies and

partnership or corporation, as the case may be to execute, deliver and perform
each of its obligations under the Notes, the Exchange Notes and the Private
Exchange Notes.  The Notes, the Exchange Notes and the Private Exchange Notes

provisions of the Indenture and, in the case of the Notes, when delivered to and

and the discretion of the court before which any proceeding therefor may be
brought.

         (v)   The Guarantor has all requisite power and authority as a limited

executed by each of the Companies and the Guarantor and authenticated by the
Trustee in accordance with the provisions of the Indenture and, in the case of

the terms of this Agreement, will constitute valid and legally binding
obligations of the Guarantor, entitled to the benefits of the Indenture and
enforceable against the Guarantor in accordance with its terms, except that the

Pledged Collateral, subject to no other security interest, claim, lien,
encumbrance or adverse interest of any nature and no right or option to acquire
the same in favor of any other person or entity, except as permitted by the
Pledge Agreement. Upon the filing of UCC-1 financing statements in appropriate
form in the requisite filing offices, the security interest, lien or pledge
created by the Pledge Agreement will be a perfected security interest with
respect to that portion of the Pledged Collateral in which a security interest
can be perfected by the filing of a financing statement, prior to all other
claims or security interests therein except as permitted by the Pledge
Agreement. The Pledge Agreement has been duly and validly authorized by Coaxial
and, when executed and delivered by Coaxial, will constitute a valid and legally

and validly authorized by each of the Companies and the Guarantor and, when
executed and delivered by the Companies and the Guarantor (assuming the due
authorization, execution and delivery by the Trustee), will constitute a valid
and legally binding agreement of each of the Companies and the Guarantor,
enforceable against each of the Companies and the Guarantor in accordance with
its terms, except that the enforcement thereof may be subject to (i) bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium or other similar

proceeding therefor may be brought.

and regulations of the FCC thereunder), except for any such violation which
would not, individually or in the aggregate, have a Material Adverse Effect, or

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

and the Guarantor of this Agreement and the Transaction Documents to which it is
a party and the consummation by each of the Companies and the Guarantor of the
transactions contemplated hereby and thereby, and the fulfillment of the terms
hereof and thereof, 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 or cause the revocation or
termination of (i) 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 the Companies or the Guarantor is a
party or to which any of them or their respective properties or assets is

applicable to any of the Companies or the Guarantor or any of their respective
properties or assets (including, without limitation, the Communications Act
and the rules and regulations of the FCC thereunder), except for any such
conflict, breach or violation which would not, individually or in the aggregate,
have a Material Adverse Effect.

        (xii)  The audited consolidated financial statements of the Companies
and Central Ohio Cable System Operating Unit included in the Memorandum present
fairly in all material respects the financial position, results of operations
and cash flows of the Companies at the dates and for the periods to which they
relate and have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis, except as otherwise stated therein.
The summary and selected financial and statistical data in the Memorandum
present fairly in all material respects the financial information shown
therein and have been prepared and compiled on a basis consistent with the
audited financial statements included therein, except as otherwise stated
therein.  Arthur Andersen LLP (the "Independent Auditors") is an independent
                                    --------------------                    
certified public accounting firm within the meaning of the Act and the rules and
regulations promulgated thereunder.

       (xiii)  There is not pending or, to the best knowledge of either Company
or the Guarantor, threatened any action, suit, proceeding, inquiry or
investigation to which any of the Companies or the Guarantor is a party, or to
which the property or assets of any of the Companies or the Guarantor is
subject, before or brought by any court or governmental agency or body which
would be required to be described in a prospectus that is subject to Item 103 of
Regulation S-K under the Act, or which seeks to restrain, enjoin, or prevent the
consummation of or otherwise challenge the issuance or sale of the Securities to
be sold hereunder or the consummation of the other transactions described in the
Memorandum under the caption "Use of Proceeds."

        (xiv)  Each of the Companies and the Guarantor possesses, or upon
consummation of the System Acquisition will possess 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 (including, without limitation, the FCC), all self-
regulatory organizations and all courts and 
<PAGE>
 
                                     -10-

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 Memorandum,
except where the failure to obtain such licenses, permits, certificates,
consents, orders, approvals and other authorizations, or to make all such
declarations and filings, would not, individually or in the aggregate, have a
Material Adverse Effect, and none of the Companies or the Guarantor has received
any notice of any proceeding relating to revocation or modification of any such
license, permit, certificate, consent, order, approval or other authorization,
except as described in the Memorandum and except where such revocation or
modification would not, individually or in the aggregate, have a Material
Adverse Effect. The licenses issued to the Companies and the Guarantor by the
FCC (the "Licenses") are valid and in full force and effect with no restrictions
          --------            
or qualifications which would have a Material Adverse Effect. No event has
occurred which permits, or with notice or lapse of time or both would permit,
and no legal governmental proceeding has been instituted or, the knowledge of
either Company or the Guarantor, threatened which could reasonably be likely to
cause, the revocation or termination of any of the Licenses or which might
reasonably be likely to result in any other impairment or modification of the
rights of either Company or the Guarantor therein which in any such case would
have a Material Adverse Effect. Except as described in the Memorandum, the
Companies have no reason to believe that any License issued by the FCC that is
required for the operation of the System will not be renewed in the ordinary
course.

         (xv)  Since the respective dates as of which information is given in
the Memorandum, except as described therein, (i) none of the Companies or the
Guarantor has incurred any liabilities or obligations, direct or contingent,
with respect to the System, except normal trade or business obligations incurred
in the ordinary course of business, the performance of which will not, to the
knowledge of either Company or the Guarantor, have a Material Adverse Effect, or
entered into or agreed to enter into any transactions or contracts (written or
oral) not in the ordinary course of business and (ii) none of the Companies or
the Guarantor has purchased any of its outstanding capital stock or other
ownership interests, nor declared, paid or otherwise made any dividend or
distribution of any kind on its capital stock or other ownership interests.

        (xvi)  Each of the Companies and the Guarantor has filed all necessary
federal, state and foreign income and franchise tax returns required to be filed

debt securities of the Companies with a view to possible downgrading, or with
negative implications, or direction not determined.

         (xiii)  The Companies and the Guarantor shall have furnished or caused
to be furnished to the Initial Purchaser such further certificates and documents
as the Initial Purchaser shall have reasonably requested.

          (xiv)  The System Acquisition shall have been consummated and the

the Guarantor shall furnish to the Initial Purchaser such conformed copies of
such opinions, certificates, letters, schedules, documents and instruments in

          8.   Indemnification and Contribution.  (a)  Each of the Companies,
               --------------------------------                              
jointly and severally, and the Guarantor agree to indemnify and hold harmless
the Initial Purchaser, each director, officer, employee or agent of the Initial
Purchaser and each person, if any, who controls the Initial Purchaser within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any
losses, claims, damages, liabilities or expenses to which the Initial
Purchaser or such direc-
<PAGE>
 
                                      -24-

tor, officer, employee, agent or controlling person may become subject under the
Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages,
liabilities or expenses (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 (A) the Memorandum or any amendment or supplement thereto or (B)
any of the Basic Documents or any application or other document, or any
amendment or supplement thereto, executed by any Issuer or based upon written
information furnished by or on behalf of any Issuer filed in any jurisdiction in
order to qualify the Securities under the securities or "Blue Sky" laws thereof
or filed with the Commission or any securities association or securities
exchange (collectively, the "Documents"); or
                             ---------      

     (ii) the omission or alleged omission to state, in the Memorandum or any
amendment or supplement thereto, or any of the Documents, a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, and
will reimburse, as incurred, the Initial Purchaser and each such director,
officer, employee, agent or controlling person for any legal or other expenses
reasonably incurred by the Initial Purchaser or such director, officer,
employee, agent or controlling person in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability, expense or action; provided, however, that
                                                        --------  -------      
none of the Companies or the Guarantor will be liable in any such case to the
Initial Purchaser or any director, officer, employee, agent or controlling
person of the Initial Purchaser to the extent that any such loss, claim,
damages, liability expense or action arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
the Memorandum or any amendment or supplement thereto, or any Document, in
reliance upon and in conformity with written information furnished to the
Companies or the Guarantor by or on behalf of the Initial Purchaser specifically
for use therein; and provided, further, that none of the Companies or the
                     --------  -------                                   
Guarantor will be liable to the Initial Purchaser or any director, officer,
employee, agent or any person controlling the Initial Purchaser with respect to
any such untrue statement or omission made in any Memorandum that is corrected
in any amendment or supplement thereto if the person asserting any such loss,
claim, damage, expense or liability purchased Securities from the Initial
Purchaser in reliance upon such Memorandum but was not sent or given a copy of
the amendment or supplement thereto 
<PAGE>
 
                                      -25-

that was made available by the Companies or the Guarantor to the Initial
Purchaser at or prior to the written confirmation of the sale of the Securities
to such person in any case where such delivery of such Memorandum (as so amended
or supplemented) is required by the Act, unless such failure to deliver such
Memorandum (as amended or supplemented) was a result of noncompliance by the
Companies or the Guarantor with Section 5(iv) of this Agreement. This indemnity
agreement will be in addition to any liability that the Companies or the
Guarantor may otherwise have to the indemnified parties. The Companies or the
Guarantor further agree that the indemnification, contribution and
reimbursement commitments set forth in this Section 8 shall apply whether or not
the Initial Purchaser is a formal party to any such lawsuits, claims or other
proceedings. Neither of the Companies nor the Guarantor will without the prior
written consent of the Initial Purchaser, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification by the Initial Purchaser may be
sought hereunder (whether or not the Initial Purchaser or any person who
controls the Initial Purchaser within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act is a party to such claim, action, suit or
proceeding), unless such settlement, compromise or consent includes an
unconditional release of the Initial Purchaser and each such director, officer,
employee, agent or controlling person from all liability arising out of such
claim, action, suit or proceeding.

          (b)  The Initial Purchaser will indemnify and hold harmless the
Companies, the Guarantor, their respective directors, officers, employees and
agents and each person, if any, who controls any of the Companies or the
Guarantor 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 of
the Companies or the Guarantor or any such director, officer, employee, agent 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 any untrue statement or alleged
untrue statement or omission of any material fact contained in the Memorandum or
any amendment or supplement thereto or any Document, in each case to the extent,
but only to the extent, that such untrue statement or alleged untrue statement
was made in reliance upon and in conformity with written information furnished
to any of the Companies or the Guarantor by or on behalf of the Initial
Purchaser specifically for use therein; and, subject to the limitation set
forth 
<PAGE>
 
                                      -26-

immediately preceding this clause, will reimburse, as incurred, any legal
or other expenses reasonably incurred by any of the Companies or the Guarantor
or any such director, officer, employee, agent 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.  This indemnity agreement will be in addition to any
liability that the Initial Purchaser may otherwise have to the indemnified
parties.

          (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability that it may have to any indemnified party except to the extent that
such omission results in the forfeiture by the indemnifying party of 
substantial rights and defenses.  In case any such action is brought against any
indemnified party, and such indemnified party 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 the named
                                        --------  -------                   
parties in any such action (including any impleaded parties) include both the
indemnified party and the indemnifying party and counsel for the indemnified
party shall have reasonably concluded that there may be one or more legal
defenses available to it and/or other indemnified parties that are different
from or additional to those available to any such indemnifying party, then the
indemnifying parties 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 8 for any legal or other expenses, other
than reasonable out-of-pocket costs of investigation, 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,
<PAGE>
 
                                      -27-

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,
representing the indemnified parties under such paragraph (a) or paragraph (b),
as the case may be, who are parties to such action or actions); (ii) the
indemnifying party has authorized in writing the employment of counsel for the
indemnified party at the expense of the indemnifying parties; or (iii) the
indemnifying party shall have failed to assume the defense or retain counsel
reasonably satisfactory to the indemnified party. After such notice from the
indemnifying parties to such indemnified party (so long as the indemnified party
shall have informed the indemnifying parties of such action in accordance with
this Section 8 on a timely basis prior to the indemnified party seeking
indemnification hereunder), the indemnifying parties will not be liable under
this Section 8 for the costs and expenses of any settlement of such action
effected by such indemnified party without the consent of the indemnifying
party, unless such indemnified party waived its rights under this Section 8, 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 8 is unavailable or insufficient to
hold harmless an indemnified party in respect of any losses, claims, damages,
expenses 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, expenses 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 Securities 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, expenses or 
liabilities (or actions in respect thereof). The relative benefits received by
the Companies and the Guarantor on the one hand and the Initial Purchaser on the
other shall be deemed to be in the same proportion as the total proceeds from
the offering of the Securities (before deducting expenses) received by the 
Compa-
<PAGE>
 
                                      -28-

nies and the Guarantor bear to the total discounts and commissions received by
the Initial Purchaser.  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 Companies or the Guarantor on the one
hand or the Initial Purchaser 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.  The amount paid or payable by a party as a result of the
losses, claims, damages and liabilities referred to above shall be deemed to
include any legal or other fees or expenses incurred by such party in connection
with investigating or defending any such claim.  The Companies and the Guarantor
and the Initial Purchaser agree that it would not be equitable if the amount of
such contribution were determined by pro rata or per capita allocation (even
if the Companies and the Guarantor on the one hand and the Initial Purchaser on
the other hand were treated as one entity for such purpose) 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), the Initial Purchaser
shall not be obligated to make contributions hereunder that in the aggregate
exceed the total discounts and commissions received by the Initial Purchaser
under this Agreement, less the aggregate amount of any damages that the Initial
Purchaser has otherwise been required to pay by reason of the untrue or alleged
untrue statements, 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 director, officer, employee or agent of and
each person, if any, who controls the 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 Purchaser, and each director, officer,
employee and agent of any of the Companies and the Guarantor and each person, if
any, who controls any of the Companies and the Guarantor 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 Companies and the Guarantor.

          (e)  Notwithstanding anything to the contrary in this Section 8, the
indemnification and contribution provisions of 
<PAGE>
 
                                      -29-

the Registration Rights Agreement shall govern any claim with respect thereto.

          9.   Offering of Securities; Restrictions on Transfer.  (a)  The
               ------------------------------------------------           
Initial Purchaser represents and warrants that it is a QIB.  The Initial
Purchaser agrees with the Companies and the Guarantor that (i) it has not and
will not solicit offers for, or offer or sell, the Securities 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 Securities only from, and will offer the Securities only to, (A) in the
case of offers inside the United States persons whom the 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 the 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, in each case, in transactions under
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 Securities
- -------                                                                     
such persons are deemed to have represented and agreed as provided under the
caption "Notice to Investors" contained in the Memorandum.

          (b)  The Initial Purchaser represents and warrants 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 Securities or has in its possession or distributes any
Memorandum or any such other material, in all cases at its own expense; (ii) the
Securities 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) it has offered the Securities and
will offer and sell the Securities (A) as part of its distribution at any time
and (B) otherwise until 40 days after the later of the commencement of the
offering and the Closing Date, only in accordance with Rule 903 of Regulation S
or as otherwise permitted in Section 9(a) and, accordingly, neither it nor any
persons acting on its behalf have engaged or 
<PAGE>
 
                                      -30-

will engage in any directed selling efforts (within the meaning of Regulation S)
with respect to the Securities, and any such persons have complied and will
comply with the offering restrictions requirements of Regulation S; and (iv) it
agrees that, at or prior to confirmation of sales of the Securities, it will
have sent to each distributor, dealer or person receiving a selling concession,
fee or other remuneration that purchases Securities from it during the
restricted period a confirmation or notice to substantially the following
effect:

     "The securities covered hereby have not been registered under the United
     States Act of 1933 (the "Act") and may not be offered and sold within the
     United States or to, or for the account or benefit of, U.S. persons (i) as
     part of the distribution of the securities at any time or (ii) otherwise
     until 40 days after the later of the commencement of the offering and the
     closing date of the offering, except in either case in accordance with
     Regulation S (or Rule 144A if available) under the Act. Terms used above
     have the meaning given to them in Regulation S."

Terms used in this Section 9 and not defined in this Agreement have the meanings
given to them in Regulation S.

          10.  Survival Clause.  The respective representations, warranties,
               ---------------                                               
agreements, covenants, indemnities and other statements of the Companies and the
Guarantor, their respective officers and the Initial Purchaser set forth in this
Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement shall remain in full force and effect, regardless of (i) any
investigation made by or on behalf of the Companies or the Guarantor, any of
their respective officers or directors, the Initial Purchaser or any controlling
person referred to in Section 8 hereof and (ii) delivery of, payment for or
disposition of the Securities, and shall be binding upon and shall inure to
the benefit of any successors, assigns, heirs or personal representatives of the
Companies or the Guarantor, the Initial Purchaser and indemnified parties
referred to in Section 8 hereof.  The respective agreements, covenants,
indemnities and other statements set forth in Sections 6 and 8 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 the Initial Purchaser by notice to the Companies and the Guarantor
given in the event that the 
<PAGE>
 
                                     -31-

Companies or the Guarantor shall have failed, refused or been unable to satisfy
all conditions on their part to be performed or satisfied hereunder on or prior
to the Closing Date or if at or prior to the Closing Date:

         (i)  any of the Companies or the Guarantor shall have sustained any
loss or interference with respect to their respective businesses or properties
from fire, flood, hurricane, earthquake, accident or other calamity, whether or
not covered by insurance, or from any labor dispute or any legal or governmental
proceeding, which loss or interference, in the sole judgment of the Initial
Purchaser, has had or has a material adverse effect on the general affairs,
management, business, condition (financial or other), properties, prospects or
results of operations of the Companies and the Guarantor, taken as a whole, or
there shall have been any material adverse change, or any development involving
a prospective material adverse change (including without limitation a change in
management or control of the Companies or the Guarantor), in the general
affairs, management, business, condition (financial or other), properties,
prospects or results of operations of the Companies and the Guarantor, taken as
a whole, except as described in or contemplated by the Memorandum (exclusive of
any amendment or supplement thereto);

        (ii)  trading in securities of the Companies or of the Guarantor or in
securities generally on the New York Stock Exchange, the American Stock
Exchange, the Montreal or Toronto Stock Exchange or the Nasdaq National Market
shall have been suspended or minimum or maximum prices shall have been 
established on any such exchange;

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

        (iv)  there shall have been (A) an outbreak or escalation of
hostilities between the United States, Canada and any foreign power, (B) an
outbreak or escalation of any other insurrection or armed conflict involving the
United States, Canada or any other national or international calamity or
emergency that in the sole judgment of the Initial Purchaser, is material and
adverse, or (C) any material change in the financial markets of the United
States or Canada that, in the case of (A), (B) or (C) above, in the sole
judgment of the Initial Purchaser, makes it impracticable or inadvisable to
proceed with the delivery of the Securities as contemplated by the Memorandum,
as amended as of the date hereof; or

         (v)  any securities of the Companies or of the Guarantor shall have
been downgraded or placed on any "watch list" for possible downgrading by any
nationally recognized statistical rating organization.

         (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.

binding upon the Initial Purchaser and each of the Companies, the Guarantor and
their respective successors and legal representatives, and nothing expressed or
mentioned in this Agreement is intended or shall be construed to give any other

part of any Issuer or the Initial Purchaser in exercising any right, power or

further exercise thereof or the exercise of any other right, power or remedy.
The remedies provided for herein are cumulative and are not exclusive of any
remedies that may be avail  able to any Company, the Guarantor or the Initial
Purchaser at law or in equity or otherwise.  No waiver of or consent to any

               Form of Opinion of Counsel to Coaxial and Phoenix

qualified would not, individually or in the aggregate, have a Material Adverse
Effect.

         (ii)  Each of the Issuers has the authorized, issued and outstanding
capitalization set forth in the Memorandum under the "as adjusted" column below

authorization, execution and delivery of the Indenture by the Trustee and the
execution, delivery and authentication of the Notes, the Exchange Notes and the
Private Exchange Notes by the Trustee in accordance with the Indenture) and
delivered by each of the Issuers and, paid for by the Initial Purchaser in
accordance with the terms of the Purchase Agreement, will constitute the valid
and legally binding obligations of each of the Issuers enforceable against each
of the Issuers in accordance with their terms, subject to applicable bankruptcy,
insolvency, reorganization, fraudulent conveyance, moratorium and similar laws
affecting creditors' rights and remedies generally and subject, as to
enforceability, to general principles of equity (regardless of whether a
proceeding is sought in equity or at law), and except that such counsel need not
express any opinion as to the enforceability of the waiver as to usury,
extension or stay laws.

          (v)  Each of the Issuers has all requisite power and authority as a
partnership or a corporation, as the case may be, to execute, deliver and
perform its obligations under the Indenture and the Notes; the Indenture is in
sufficient form for qualification under the TIA; the Indenture has been duly and
validly authorized by each of the Issuers and, when duly executed and delivered

accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, fraudulent conveyance, moratorium and similar laws affecting
creditors' rights and remedies generally and subject, as to enforceability, to
general principles of equity (regardless of whether a proceeding is sought in
equity or at law), and except that such counsel need not express any opinion as
to the enforceability of the waiver as to usury, extension or stay laws.

         (vi)  Each of the Issuers has all requisite power and authority as a
partnership or a corporation, as the case may be, to execute, deliver and
perform its obligations under the Registration Rights Agreement; the
Registration Rights Agreement has been duly and validly authorized by each of
the Issuers and when duly executed and delivered by each of the Issuers, will

applicable bankruptcy, insolvency, reorganization, moratorium and similar

                                      -5-

laws affecting creditors' rights and remedies generally and subject, as to

rights to indemnity or contribution thereunder.

        (vii)  Each of the Issuers has all requisite power and authority as a

the Guarantor.  This Agreement has been duly executed and delivered by each of
the Issuers.

       (viii)  Each of the Issuers has all requisite power and authority, as
a partnership or a corporation, as the case may be, to execute, deliver and
perform each of their obligations under the Transaction Documents.  The
Transaction Documents have been duly and validly authorized by each of the
Issuers and, when executed and delivered by the Issuers, will constitute a valid
and legally binding agreement of each of the Issuers enforceable against each of
the Issuers in accordance with its terms, except that the enforcement thereof
may be subject to (a) bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (b) general principles of equity and
the discretion of any proceeding therefor may be brought.

Issuer)), (ii) in violation of any statute, judgment, decree, order, rule or
regulation applicable to any of them or any of their respective properties or
assets, except for any such violation which would not, individually or in the
aggregate, have a Material Adverse Effect, or (iii) in breach or default in the
performance or observance of (nor has any event occurred which, with notice or
passage of time or both, would constitute a default under) any obligation,
agreement, covenant or condition contained in any indenture, mortgage, deed of
trust, loan agreement, note, lease, license, franchise agreement, permit,
certificate, contract or other agreement or instrument known to such counsel
(including in any event any of the foregoing which have been filed by the
Issuers or the Guarantor with the Commission) to which any of them is a party or
to which any of them or their respective properties or assets is subject, except
for any such breach, default or event which would not, individually or in the
aggregate, have a Material Adverse Effect.

Indenture, the Registration Rights Agreement, the Pledge Agreement and the
Transaction Documents (including, without limitation, the Contribution
Agreement) and the consummation of the transactions contemplated hereby and
thereby (including, without limitation, the issuance and sale of the Securities
to the Initial Purchaser) will not conflict with or constitute or result in a
breach or violation 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

default or event which would not, individually or in the aggregate, have a
Material Adverse Effect, (ii) the certificate of incorporation or bylaws (or
similar organizational document (including any certificate of limited liability
Issuer)) of any of the Issuers, or (iii) (assuming compliance with all

Purchase Agreement) any statute, judgment, decree, order, rule or regulation
known to such counsel to be applicable to any of the Issuers or any of their

of the FCC;

          (xvi)   No consent, approval, authorization, order, registration or

rules and regulations of the FCC for the execution and delivery by each of the

FCC Licenses, which in either case could have a material adverse effect on the
Issuers taken as a whole;

          (xx)    To the best of our knowledge after due inquiry, no event has
occurred which permits, or with notice or lapse of time or both would permit,
the revocation or non-renewal of any of the FCC Licenses, assuming the filing of
timely license renewal applications and the timely payment of all applicable
filing and regulatory fees to the FCC, or which might result in any other
material impairment of the rights of the Issuers in the FCC Licenses; and

have a Material Adverse Effect, or (iii) in breach or default in the performance
or observance of (nor has any event occurred which, with notice or passage of
time or both, would constitute a default under) any obligation, agreement,
covenant or condition contained in any indenture, mortgage, deed of trust, loan
agreement, note, lease, license, franchise agreement, permit, certificate,
contract or other agreement or instrument known to such counsel (including in

Documents and the consummation of the transactions contemplated hereby and
thereby (including, without limitation, the Contribution Agreement) will not
conflict with or constitute or result in a breach or violation 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
indenture, mort gage, deed of trust, loan agreement, note, lease, license,

any such conflict, breach, violation, default or event which would not,

(assuming compliance with all applicable state securities or "Blue Sky" laws and
assuming the accuracy of the representations and warranties of the Initial
Purchaser in Section 9 of the Purchase Agreement) any statute, judgment, decree,
order, rule or regulation known to such counsel to be applicable to the
Guarantor or any of their respective properties or assets, except for any such
conflict, breach or violation which would not, individually or in the aggregate,
have a Material Adverse Effect.

chaser or the other transactions contemplated hereby, except such as may be

and those which have previously been obtained.

          (xiv)   No registration under the Act of the Securities is required in
connection with the sale of the Notes to the Initial Purchaser as contemplated
by this Agreement and the Memorandum or in connection with the initial resale of
the Securities by the Initial Purchaser in accordance with Section 9 of the
Purchase Agreement, and prior to the commencement of the Exchange Offer (as
defined in the Registration Rights Agreement) or the effectiveness of the Shelf
Registration Statement (as defined in the Registration Rights Agreement), the
Indenture is not required to be qualified under the TIA, in each case assuming
(i) that the purchasers who buy the Notes in the initial resales are qualified
institutional buyers as defined in Rule 144A promulgated under the Act ("QIBs"
or "Qualified Institutional Buyers"), accredited investors as defined in Rule
501(a) (1), (2), (3) or (7) promulgated under the Act ("Accredited Investors")

                                      -6-

conditions to effect the System Acquisition set forth in the Contribution
Agreement have been satisfied without waiver.

          (xvii)  The Pledge Agreement has been duly authorized and executed by
the parties thereto. The Pledge Agreement, together with the delivery of
certificates evidencing the Pledged Securities Shares (as defined in the Pledge
Agreement), duly endorsed in the name of the Trustee or in blank (or accompanied
by an appropriate stock power or separate document of assignment duly executed
in the name of the Trustee or in blank), to the Trustee in the State of New
York, will create in favor of the Trustee a valid and perfected security
interest therein as security for the Secured Obligations (as defined in the
Pledge Agreement). Assuming that the Trustee took delivery of the Pledged
Securities without notice of any adverse claim (within the meaning of the
Uniform Commercial Code as in effect in the State of New York as of the date
hereof (the "UCC")), the Trustee will acquire its interest in the Pledged
Securities free of any adverse claim.

          (xviii) The Pledge Agreement creates in favor of the Trustee Agent (as
defined in the Security Agreement) for the benefit of the Secured Parties (as
defined in the Security Agreement) a valid security interest in Pledged
Collateral and the Pledged Collateral (as defined in the Security Agreement) in
each case to the extent that the Uniform Commercial Code of the State of New
York (the "New York UCC") is applicable thereto and governs the creation of
           ------------                                                    
security interest therein.

          Such counsel shall additionally state that in its capacity as counsel
to the Guarantor, it has participated in conferences with officers and other
representatives of the Issuers and Insight, representatives of the independent
public accountants for the Issuers and representatives of the Initial Purchaser
at which the contents of the Memorandum and related matters were discussed and,
although it is not passing upon and does not assume any responsibility for the
accuracy, complete ness or fairness of the statements contained in the
Memorandum (except as indicated in clause (x) above) and has not made any
independent check or verification thereof, on the basis of the foregoing
(relying as to materiality to a large extent upon the statements of officers and
other representatives of the Guarantor) no facts have come to its attention
that have caused it to believe that the Memorandum as of its date and as of the
date hereof, or any amendment or supplement thereto as of its date and as of the
date hereof, contained or contains an untrue

statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading (it being understood that such
counsel need express no opinion on the financial statements or other financial
and statistical data included in the Memorandum).

 2.  Exchange Offer
 --  --------------

               (a)  Each of the Guarantor and the Issuers agrees to use its
     reasonable best efforts to file with the SEC as soon as practicable after
     the Closing, but in no event later than the Filing Date, an offer to
     exchange (the "Exchange Offer") any and all of the Registrable Notes (other
     than the Private Exchange Notes, if any) for a like aggregate principal
     amount of debt securities of the Issuers which are identical to the Notes
     (the "Exchange Notes") (and which are entitled to the benefits of the
     Indenture or a trust indenture which is substantially identical to the
     Indenture in all material respects (other than such changes to the
     Indenture or any such identical trust indenture as are necessary to comply
     with any requirements of the SEC to effect or maintain the qualification
     thereof under the TIA) and which, in either case, has been qualified under
     the TIA), except that the Exchange Notes (other than the Private Exchange
     Notes, if any) shall have been registered pursuant to an effective
     Registration Statement under the Securities Act and will not contain terms
     with respect to transfer restrictions. The Exchange Offer will be
     registered under the Securities Act on the appropriate form (the "Exchange
     Registration Statement") and will comply with all applicable tender offer
     rules and regulations under the Exchange Act. Each of the Guarantor and the
     Issuers agrees to use its reasonable best efforts to (x) cause the Exchange
     Registration Statement to become effective under the Securities Act on or
     before the Effectiveness Date; (y)
<PAGE>
 
                                      -6-


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
180th day following the Issue Date. If after such Exchange 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, such Exchange Registration Statement shall be deemed not to
have become effective for purposes of this Agreement. Each Holder who
participates in the Exchange Offer will be required to represent that any
Exchange Notes received by it will be acquired in the ordinary course of its
business, that at the time of the consummation of the Exchange Offer such Holder
will have 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, that such Holder is not an affiliate of any of the Issuers, the
Guarantor or their subsidiaries within the meaning of Rule 405 promulgated under
the Securities Act or if it is such an affiliate, that it will comply with the
registration and prospectus delivery requirements of the Securities Act, to the
extent applicable and that it is not acting on behalf of any Person who could
not truthfully make the foregoing representations. Upon consummation of the
Exchange Offer in accordance with this Section 2, the provisions of this
Agreement shall continue to apply, mutatis mutandis, solely with respect to
                                   ------- --------
Registrable Notes that are Private Exchange Notes and Exchange Notes held by
Participating Broker-Dealers, and the Issuers and the Guarantor shall have no
further obligation to register Registrable Notes (other than Private Exchange
Notes and Exchange Notes held by Participating Broker-Dealers) pursuant to
Section 3 of this Agreement.

          (b) The Issuers and the Guarantor shall include within the Prospectus
contained in the Exchange Registration Statement a section entitled "Plan of
Distribution," reasonably acceptable to the Initial Purchaser, which shall
contain a summary statement of the positions taken or policies made by the staff
of the SEC with respect to the potential "underwriter" status of any 
<PAGE>
 
                                      -7-


    broker-dealer that is the beneficial owner (as defined in Rule 13d-3
    promulgated under the Exchange Act) of Exchange Notes received by such
    broker-dealer in the Exchange Offer (a "Participating Broker-Dealer"),
    whether such positions or policies have been publicly disseminated by the
    staff of the SEC or such positions or policies, in the reasonable judgment
    of the Initial Purchaser, represent the prevailing views of the staff of the
    SEC. Such "Plan of Distribution" section shall also allow the use of the
    Prospectus by all Persons subject to the prospectus delivery requirements of
    the Securities Act, including all Participating Broker-Dealers, and include
    a statement describing the means by which Participating Broker-Dealers may
    resell the Exchange Notes.

          Each of the Guarantor and the Issuers shall use its reasonable best
efforts to keep the Exchange 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 such Persons must
comply with such requirements in order to resell the Exchange Notes, provided
                                                                     --------
that such period shall not exceed 180 days (or such longer period if extended
pursuant to the last paragraph of Section 5) (the "Applicable Period").

          If, upon consummation of the Exchange Offer, the Initial Purchaser
holds any Notes acquired by it and having, or which are reasonably likely to be
determined to have, the status as an unsold allotment in the initial
distribution, the Issuers and the Guarantor upon the request of the Initial
Purchaser shall, simultaneously with the delivery of the Exchange Notes in the
Exchange Offer, issue and deliver to the Initial Purchaser, in exchange (the
"Private Exchange") for the Notes held by the Initial Purchaser, a like
principal amount of debt securities of the Issuers that are identical in all
material respects to the Exchange Notes (the "Private Exchange Notes") (and
which are issued pursuant to the same indenture as the Exchange Notes) except
for the placement of a restrictive legend on the Private Exchange Notes. If
possible, the Private Exchange Notes shall bear the same CUSIP number as the
Exchange Notes. Interest on the Exchange Notes and Private Exchange Notes will
accrue from the last interest payment date on which interest was paid on the
Notes surrendered in exchange therefor 
<PAGE>
 
                                      -8-


or, if no interest has been paid on the Notes, from the Issue Date.

           In connection with the Exchange Offer, the Issuers and the Guarantor
shall:

     (i)   mail to each Holder a copy of the Prospectus forming part of the
     Exchange Registration Statement, together with an appropriate letter of
     transmittal and related documents;

     (ii)  utilize the services of a depositary for the Exchange Offer with an
     address in the Borough of Manhattan, The City of New York which may be the
     Trustee or an affiliate thereof; and

     (iii) permit Holders to withdraw tendered Notes 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.

           As soon as practicable after the close of the Exchange Offer or the
Private Exchange, as the case may be, the Issuers and the Guarantor shall:

     (i)   accept for exchange all Notes tendered and not validly withdrawn
     pursuant to the Exchange Offer or the Private Exchange;

     (ii)  deliver to the Trustee for cancellation all Notes so accepted for
     exchange; and

     (iii) cause the Trustee to authenticate and deliver promptly to each Holder
     of Notes, Exchange Notes or Private Exchange Notes, as the case may be,
     equal in principal amount to the Notes of such Holder so accepted for
     exchange.

           The Exchange Notes and the Private Exchange Notes may be issued under
(i) the Indenture or (ii) an indenture substantially identical to the Indenture,
which in either event will provide that (1) the Exchange Notes will not be
subject to the transfer restrictions set forth in the Indenture and (2) the
Private Exchange Notes will be subject to the transfer restrictions set forth in
the Indenture. The Indenture or such 
<PAGE>
 
                                      -9-


indenture shall provide that the Exchange Notes, the Private Exchange Notes and
the Notes will vote and consent together on all matters as one class and that
neither the Exchange Notes, the Private Exchange Notes nor the Notes will have
the right to vote or consent as a separate class on any matter.

               (a) If (1) prior to the consummation of the Exchange Offer, the
     Issuers and the Guarantor or Holders of at least a majority in aggregate
     principal amount of the Registrable Notes reasonably determine in good
     faith that (i) the Exchange Notes would not, upon receipt, be tradeable by
     such Holders which are not affiliates (within the meaning of the Securities
     Act) of the Issuers and the Guarantor without restriction under the
     Securities Act and without restrictions under applicable state securities
     laws, (ii) the interests of the Holders under this Agreement would be
     adversely affected by the consummation of the Exchange Offer or (iii) after
     conferring with counsel, the SEC is unlikely to permit the commencement of
     the Exchange Offer prior to the Effectiveness Date, (2) subsequent to the
     consummation of the Private Exchange, any holder of the Private Exchange
     Notes so requests or (3) the Exchange Offer is commenced and not
     consummated within 180 days of the Issue Date, then the Issuers and the
     Guarantor shall promptly deliver to the Holders and the Trustee written
     notice thereof (the "Shelf Notice") and shall file an Initial Shelf
     Registration pursuant to Section 3. Following the delivery of a Shelf
     Notice to the Holders of Registrable Notes (in the circumstances
     contemplated by clauses (1) and (3) of the preceding sentence), the Issuers
     and the Guarantor shall not have any further obligation to conduct the
     Exchange Offer or the Private Exchange under this Section 2.

               (b) As a condition to its participation in the Exchange Offer
     pursuant to the terms of this Agreement, each Holder represents and
     warrants to the Issuers and the Guarantor that, (A) it is not an affiliate
     of the Issuers and the Guarantor, (B) it is not engaged in, and does not
     intend to engage in, and has no arrangement or understanding with any
     Person to participate in, a distribution of the Exchange Notes to be issued
     in the Exchange Offer, and (C) it is acquiring the Exchange Notes in its
     ordinary course of business. Each Holder hereby acknowledges and agrees
     that any Participating Broker-
<PAGE>
 
                                     -10-


     Dealer and any Holder using the Exchange Offer to participate in a
     distribution of Exchange Notes (1) could not under SEC policy as in effect
     on the date of this Agreement rely on the position of the SEC enunciated in
     Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital 
     ---------------------------                               -------------
     Holdings Corporation (available May 13, 1988), as interpreted in the SEC's
     --------------------
     letter to Shearman & Sterling dated July 2, 1993, and similar no-action
     letters, and (2) must comply with the registration and prospectus delivery
     requirements of the Securities Act in connection with a secondary resale
     transaction and that such a secondary resale transaction must be covered by
     an effective registration statement containing the selling security holder
     information required by Item 507 or 508, as applicable, of Regulation S-K
     if the resales are of Notes obtained by such Holder in exchange for Notes
     acquired by such Holder directly from the Issuers and the Guarantor or an
     affiliate thereof.

 1.  Shelf Registration
 --  ------------------

           If a Shelf Notice is delivered as contemplated by Section 2(c), then:

               (a) Initial Shelf Registration.  The Issuers and the Guarantor 
               --- --------------------------
     shall prepare and 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 (the "Initial Shelf Registration"). If the Issuers
     and the Guarantor shall have not yet filed an Exchange Registration
     Statement, the Issuers and the Guarantor shall use their best efforts to
     file with the SEC the Initial Shelf Registration on or prior to the Filing
     Date. In any other instance, the Issuers and the Guarantor shall use their
     reasonable best efforts to file with the SEC the Initial Shelf Registration
     within 30 days of the delivery of the Shelf Notice. The Initial Shelf
     Registration shall be on Form S-1 or another appropriate form permitting
     registration of such Registrable Notes for resale by such Holders in the
     manner or manners designated by them (including, without limitation, one or
     more underwritten offerings). The Issuers and the Guarantor 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
<PAGE>
 
                                     -11-


     Issuers and the Guarantor shall use their reasonable best efforts to cause
     the Initial Shelf Registration to be declared effective under the
     Securities Act, if an Exchange Registration Statement has not yet been
     declared effective, on or prior to the Effectiveness Date, or, in any other
     instance, as soon as practicable thereafter and in no event later than 45
     days after filing of the Initial Shelf Registration, and to keep the
     Initial Shelf Registration continuously effective under the Securities Act
     until the date which is 24 months from the date on which such Initial Shelf
     Registration is declared effective (subject to extension pursuant to the
     last paragraph of Section 5 hereof), 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 (ii) a Subsequent Shelf Registration covering all of the
     Registrable Notes has been declared effective under the Securities Act (the
     "Effectiveness Period").

          (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 the securities registered thereunder), the Issuers and the Guarantor
     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 amend the Shelf
     Registration in a manner reasonably expected 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 (a "Subsequent Shelf Registration"). If a Subsequent
     Shelf Registration is filed, the Issuers and the Guarantor shall use their
     reasonable best efforts to cause the Subsequent Shelf Registration to be
     declared effective as soon as practicable after such filing and to keep
     such Registration Statement 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
<PAGE>
 
                                     -12-


     term "Shelf Registration" means the Initial Shelf Registration and any
     Subsequent Shelf Registration.

          (c) Supplements and Amendments.  The Issuers and the Guarantor shall
          --- --------------------------
     promptly supplement and amend the 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
     requested by the Holders of a majority in aggregate principal amount of the
     Registrable Notes covered by such Registration Statement or by any
     underwriter(s) of such Registrable Notes.

 2.  Additional Interest
 --  -------------------

          (a) The Issuers, the Guarantor and the Initial Purchaser agree that
     the Holders of Registrable Notes will suffer damages if the Issuers and the
     Guarantor 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 and the Guarantor agree to
     pay additional interest on the Notes ("Additional Interest") under the
     circumstances and to the extent set forth below:

     (i)   if the Exchange Registration Statement has not been filed on or prior
     to the Filing Date;

     (ii)  if the Exchange Registration Statement has not been declared
     effective on or prior to the Effectiveness Date;

     (iii) if an Initial Shelf Registration required by Section 2(c) has not
     been filed on or prior to the date required by Section 3(a);

     (iv)  if an Initial Shelf Registration required by Section 2(c) has not
     been declared effective on or prior to the date required by Section 3(a);
     and/or

     (v)   if (A) the Issuers have not exchanged the Exchange Notes for all
     Notes validly tendered in accordance with the terms of the Exchange Offer
     on or prior to 180 days after the Issue Date or (B) the Exchange
     Registration Statement ceases to be effective at any time prior to the time
     that the Exchange Offer is consummated or (C) if
<PAGE>
 
                                     -13-


     applicable, the Shelf Registration has been declared effective and such
     Shelf Registration ceases to be effective at any time during the
     Effectiveness Period;

(each such event referred to in clauses (i) through (v) above is a "Registration
Default"), the sole remedy available to Holders of the Notes will be the
immediate accrual of Additional Interest as follows:  the per annum interest
rate on the Notes will increase by 50 basis points during the first 90-day
period following the occurrence of a Registration Default and until it is waived
or cured; and the per annum interest rate will increase by an additional 25
basis points for each subsequent 90-day period during which the Registration
Default remains uncured, up to a maximum additional interest rate of 200 basis
points per annum, provided, however, that only Holders of Private Exchange Notes
                  --------  -------                                             
shall be entitled to receive Additional Interest as a result of a Registration
Default pursuant to clause (iii) or (iv), provided, further, that (1) upon the
                                          --------  -------                   
filing of the Exchange Registration Statement or the Initial Shelf Registration
(in the case of (i) above), (2) upon the effectiveness of the Exchange
Registration Statement or a Shelf Registration (in the case of (ii) above), (3)
upon the filing of the Shelf Registration (in the case of (iii) above), (4) upon
the effectiveness of the Shelf Registration (in the case of (iv) above), or (5)
upon the exchange of Exchange Notes for all Notes tendered (in the case of
(v)(A) above), or upon the effectiveness of the Exchange Registration Statement
which had ceased to remain effective (in the case of (v)(B) above), or upon the
effectiveness of the Shelf Registration which had ceased to remain effective (in
the case of (v)(C) above), Additional Interest on the Notes as a result of such
clause (i), (ii), (iii), (iv) or (v) (or the relevant subclause thereof), as the
case may be, shall cease to accrue and the interest rate on the Notes will
revert to the interest rate originally borne by the Notes.

               (b) The Issuers and the Guarantor shall notify the Trustee within
     one business day 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) of this
     Section 4 will be payable in cash semi-annually on each February 15 and
     August 15 (to the Holders of record on the February 1 and August 1
     immediately preceding such dates), commencing with the first such date
<PAGE>
 
                                      -14-



     occurring after any such Additional Interest commences to accrue and until
     such Registration Default is cured, by depositing with the Trustee, in
     trust for the benefit of such Holders, immediately available funds in sums
     sufficient to pay such Additional Interest. 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.

3.   Registration Procedures
- --   -----------------------

        In connection with the filing of any Registration Statement pursuant to
Section 2 or 3 hereof, the Issuers and the Guarantor 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
the Issuers and the Guarantor shall:

        (a)     Prepare and file with the SEC, prior to the Filing Date, a
     Registration Statement or Registration Statements as prescribed by Section
     2 or 3, 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, or (2)
             --------
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered under the Securities Act by any
     Participating Broker-Dealer who seeks to sell Exchange Notes during the
     Applicable Period, before filing any Registration Statement or Prospectus
     or any amendments or supplements thereto, the Issuers and the Guarantor
     shall, if requested, furnish to and afford the Holders of the Registrable
     Notes covered by such Registration Statement and each such Participating
     Broker-Dealer, as the case may be, their counsel and the managing
     underwriter(s), if any, a reasonable opportunity to review copies of all
     such documents (including copies of any documents to be incorporated by
     reference therein and all exhibits thereto) proposed to be filed (at least
     5 business days 
<PAGE>
 
                                      -15-

     prior to such filing). The Issuers and the Guarantor shall not file any
     Registration Statement or Prospectus or any amendments or supplements
     thereto in respect of which the Holders must be afforded an opportunity to
     review prior to the filing of such document, if the Holders of a majority
     in aggregate principal amount of the Registrable Notes covered by such
     Registration Statement, or such Participating Broker-Dealer, as the case
     may be, their counsel, or the managing underwriter(s), if any, shall
     reasonably object.

        (b)     Prepare and file with the SEC such amendments and post-effective
     amendments to each Shelf Registration or Exchange 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) under the Securities Act; and comply with the provisions of
     both the Securities Act and the Exchange Act, and the rules and regulations
     of the SEC thereunder, applicable to 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 Participating Broker-Dealer
     covered by any such Prospectus; the Issuers and the Guarantor shall be
     deemed not to have used their reasonable best efforts to keep a
     Registration Statement effective during the Applicable Period if any of
     them voluntarily takes any action that would result 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 unless such action is
     required by applicable law or unless the Issuers and the Guarantor comply
     with this Agreement, including without limitation, the provisions of clause
     5(c)(v) below.

        (c)     If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section
<PAGE>
 
                                      -16-

     2 is required to be delivered under the Securities Act by any Participating
     Broker-Dealer who seeks to sell Exchange Notes during the Applicable
     Period, notify the selling Holders of Registrable Notes, or each such
     Participating Broker-Dealer, as the case may be, their counsel and the
     managing underwriter(s), if any, promptly (but in any event within two
     business days), and confirm such notice in writing, (i) when a Prospectus
     or any prospectus supplement or post-effective amendment thereto has been
     filed, and, with respect to a Registration Statement or any post-effective
     amendment thereto, when the same has become effective under the Securities
     Act (including in such notice a written statement that any Holder may, upon
     request, obtain, without charge, one conformed copy of such Registration
     Statement or post-effective amendment thereto including financial
     statements and schedules, 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 and the Guarantor contained in any agreement (including any
     underwriting agreement) contemplated by Section 5(n) below cease to be true
     and correct, (iv) of the receipt by the Issuers and the Guarantor 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 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 
<PAGE>
 
                                      -17-

     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 or necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading,
     and (vi) of the Issuers' and the Guarantor's reasonable 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, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, use their 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 their reasonable best efforts to obtain the withdrawal of
     any such order at the earliest possible moment.

        (e)     If a Shelf Registration is filed pursuant to Section 3 and if
     requested by the managing underwriter(s), if any, or the Holders of a
     majority in aggregate principal amount of the Registrable Notes being sold
     in connection with an underwritten offering, (i) promptly incorporate in a
     Prospectus supplement or post-effective amendment such information as the
     managing underwriter(s), if any, or such Holders reasonably request to be
     included therein and (ii) make all required filings of such Prospectus
     supplement or such post-effective amendment as soon as practicable after
     the Issuers and the Guarantor have received notification of the matters to
     be incorporated in such Prospectus supplement or post-effective amendment.

        (f)     If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, furnish to each selling Holder of Registrable Notes
     who so requests and to each such Participating Broker-Dealer who so
     requests and to counsel and the managing underwriter(s), if any, without
     charge, one conformed copy of the Registration Statement or Registration
     Statements and each post-effective amendment thereto, including financial
     statements and schedules, and, if requested, all documents incorporated or
     deemed to be incorporated therein by reference and all exhibits.

     counsel, and the managing underwriter or underwriters, if any, without
     charge, as many copies of the Prospectus or Prospectuses (including each
     form of preliminary Prospectus) and each amendment or supplement thereto
     and any documents incorporated by reference therein as such Persons may
     reasonably request; and, subject to the last paragraph of this Section 5,
     the Issuers and the Guarantor hereby consent to the use of such Prospectus
     and each amendment or supplement thereto by each of the selling Holders of
     Registrable Notes or each such Participating Broker-Dealer, as the case may
     be, and the managing underwriter or underwriters or agents, if any, and

     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 Registration Statement
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the
<PAGE>
 
                                      -19-

     Applicable Period, to use their reasonable best efforts to register or
     qualify, and to cooperate with the selling Holders of Registrable Notes 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 of (or exemption from
     such registration or qualification), such Registrable Notes for offer and
     sale under the securities or Blue Sky laws of such jurisdictions within the
     United States as any selling Holder, Participating Broker-Dealer, or the
     managing underwriter or underwriters, if any, 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 and the Guarantor agree to cause their counsel to

     required to be filed pursuant to this Section 5(h); keep each such
     registration or qualification (or exemption therefrom) effective during the
     period such Registration Statement is required to be kept effective and 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 the Issuers and the
                                        --------
     Guarantor shall not 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.

        (i)     If a Shelf Registration is filed pursuant to Section 3,
     cooperate with the selling Holders of Registrable Notes and the managing
     underwriter or underwriters, if any, to facilitate the timely preparation
     and delivery of certificates representing Registrable Notes to be sold,

                                      -20-

        (j)     Use their 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 necessary to
     enable the seller or sellers thereof or the managing 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 Issuers and the Guarantor
     will cooperate in all reasonable respects with the filing of such
     Registration Statement and the granting of such approvals.

        (k)     If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, upon the occurrence of any event contemplated by
     paragraph 5(c)(v) or 5(c)(vi), as promptly as reasonably practicable
     prepare and (subject to Section 5(a)) file with the SEC, at the expense of

     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.

        (l)     Use their reasonable best efforts to cause the Registrable Notes
     covered by a Registration Statement or the Exchange Notes, as the case may
     be, to be rated with the appropriate rating agencies, if so requested by
     the Holders of a majority in aggregate principal amount of Registrable
     Notes covered by such Registration Statement or the Exchange Notes, as the
     case may be, or the managing underwriter or underwriters, if any.
<PAGE>
 
                                      -21-

        (m)     Prior to the effective date of the first Registration Statement
     relating to the Registrable Notes, (i) provide the Trustee with

     be, in a form eligible for deposit with The Depository Trust Company and
     (ii) provide a CUSIP number for the Registrable Notes or Exchange Notes, as
     the case may be.

        (n)     In connection with an underwritten offering of Registrable Notes

     is customary in underwritten offerings of debt securities similar to the
     Notes and take all such other actions as are reasonably requested by the
     managing underwriter(s), if any, in order to expedite or facilitate the
     registration or the disposition of such Registrable Notes, and in such
     connection, (i) to the extent possible, make such representations and
     warranties to the managing underwriter or underwriters on behalf of any
     underwriters, with respect to the business of the Issuers, the Guarantor
     and their subsidiaries and the Registration Statement, Prospectus and
     documents, if any, incorporated or deemed to be incorporated by reference

     the Issuers and the Guarantor and updates thereof in form and substance

     securities similar to the Notes and such other matters as may be reasonably
     requested by the managing underwriter(s); (iii) obtain "cold comfort"
     letters and updates thereof in form and substance reasonably satisfactory
     to the managing underwriter or underwriters from the independent certified
     public accountants of the Issuers and the Guarantor (and, if necessary, any
     other independent certified public accountants of any subsidiary of any of
     the Issuers and the Guarantor or of any business acquired by the Issuers or
     the Guarantor for which financial statements and financial data are, or are
     required to be, included in the Registration Statement), addressed to the
     managing underwriter or underwriters on 
<PAGE>
 
                                      -22-

     behalf of any 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
     Notes and such other matters as may be reasonably requested by the managing
     underwriter or underwriters; and (iv) if an underwriting agreement is
     entered into, the same shall contain indemnification provisions and
     procedures no less favorable than those set forth in Section 7 hereof (or
     such other provisions and procedures acceptable to Holders of a majority in
     aggregate principal amount of Registrable Notes covered by such
     Registration Statement and the managing underwriter or underwriters or
     agents) with respect to all parties to be indemnified pursuant to said
     Section. The above shall be done at each closing under such underwriting
     agreement, or as and to the extent required thereunder.

        (o)     If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, 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, the managing underwriter or underwriters
     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 (collectively,
     the "Inspectors"), at the offices where normally kept, during reasonable
     business hours, all financial and other records, pertinent corporate
     documents and properties of the Issuers, the Guarantor and their respective
     subsidiaries (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, the
     Guarantor and their respective subsidiaries to supply all information in
     each case reasonably requested by any such Inspector in connection with
     such Registration Statement. Records which the Issuers and the Guarantor
     determine, in good faith, to be confidential and any Records which they
     notify the Inspectors are confidential shall not be 
<PAGE>
 
                                      -23-

     disclosed by the Inspectors unless (i) the disclosure of such Records is
     necessary to avoid or correct a material misstatement or material omission
     in such Registration Statement, (ii) the release of such Records is ordered
     pursuant to a subpoena or other order from a court of competent
     jurisdiction or (iii) the information in such Records has been made
     generally available to the public. Each selling Holder of such Registrable
     Notes and each such Participating Broker-Dealer or underwriter will be
     required to agree that information obtained by it as a result of such
     inspections shall be deemed confidential and shall not be used by it as the
     basis for any market transactions in the securities of the Issuers and the
     Guarantor or for any purpose other than in connection with such
     Registration Statement unless and until such is made generally available to
     the public. Each selling Holder of such Registrable Notes and each such
     Participating Broker-Dealer will be required to further agree that it will,
     upon learning that disclosure of such Records is sought in a court of
     competent jurisdiction, give prompt notice to the Issuers and the Guarantor
     and allow the Issuers and the Guarantor to undertake appropriate action to
     prevent disclosure of the Records deemed confidential at their expense.

        (p)     Provide an indenture trustee for the Registrable Notes or the
     Exchange Notes, as the case may be, and cause the Indenture or the trust
     indenture provided for in Section 2(a), as the case may be, to be qualified
     under the TIA not later than the effective date of the Exchange
     Registration Statement or 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 their 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.

        (q)     Comply with all applicable rules and regulations of the SEC and
     make generally available to its 
<PAGE>
 
                                      -24-

     securityholders earnings statements satisfying 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 45 days after the end
     of any 12-month period (or 90 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 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 and the Guarantor after the effective date of
     a Registration Statement, which statements shall cover said 12-month
     periods.

        (r)     Upon consummation of an Exchange Offer or a Private Exchange,
     obtain an opinion or opinions of counsel to the Issuers and the Guarantor,
     in a form customary for underwritten offerings of debt securities similar
     to the Notes, 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, and which includes an opinion that (i) the
     Issuers and the Guarantor have duly authorized, executed and delivered the
     Exchange Notes and Private Exchange Notes and the related indenture and
     (ii) each of the Exchange Notes or the Private Exchange Notes, as the case
     may be, and related indenture constitutes a legal, valid and binding
     obligation of the Issuers and the Guarantor, enforceable against the
     Issuers and the Guarantor in accordance with its respective terms (with
     customary exceptions).

        (s)     If an Exchange Offer or a Private Exchange is to be consummated,
     upon delivery of the Registrable Notes by Holders to the Issuers and the
     Guarantor (or to such other Person as directed by the Issuers and the
     Guarantor) in exchange for the Exchange Notes or the Private Exchange
     Notes, as the case may be, the Issuers and the Guarantor shall mark, or
     cause to be marked, on such Registrable Notes that such Registrable Notes
     are being canceled in exchange for the Exchange Notes or the Private
     Exchange Notes, as the case may be; and, in no event shall such Registrable
     Notes be marked as paid or otherwise satisfied.
<PAGE>
 
                                      -25-

        (t)     Cooperate with each seller of Registrable Notes covered by any
     Registration Statement and the managing underwriter(s), 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").

        (u)     Use their reasonable best efforts to take all other reasonable
     steps necessary to effect the registration of the Registrable Notes covered
     by a Registration Statement contemplated hereby.

        The Issuers and the Guarantor may require each seller of Registrable
Notes or Participating Broker-Dealer as to which any registration is being
effected to furnish to the Issuers and the Guarantor such information regarding
such seller or Participating Broker-Dealer and the distribution of such
Registrable Notes or Exchange Notes to be sold by such Participating Broker-
Dealer, as the case may be, as the Issuers and the Guarantor may, from time to
time, reasonably request. The Issuers and the Guarantor may exclude from such
registration the Registrable Notes of any seller or Participating Broker-Dealer
who unreasonably 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 and the Guarantor all
information required to be disclosed in order to make the information previously
furnished to the Issuers and the Guarantor by such seller not materially
misleading.

        Each Holder of Registrable Notes and each Participating Broker-Dealer
agrees by acquisition of such Registrable Notes or Exchange Notes to be sold by
such Participating Broker-Dealer, as the case may be, that, upon receipt of any
notice from the Issuers and the Guarantor 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(k), or until it is
advised in writing (the "Advice") by the 
<PAGE>
 
                                      -26-

Issuers and the Guarantor that the use of the applicable Prospectus may be
resumed, and has received copies of any amendments or supplements thereto. In
the event the Issuers and the Guarantor shall give any such notice, each of the
Effectiveness Period and the Applicable Period shall be extended by the number
of days during such periods from and including the date 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 Holder or
Participating Broker-Dealer, as the case may be, shall have received (x) the
copies of the supplemented or amended Prospectus contemplated by Section 5(k) or
(y) the Advice.

     local counsel) chosen by the Holders of a majority in aggregate principal
     amount of the Registrable

     Notes to be included in such Registration Statement and other reasonable
     out-of-pocket expenses of the Holders of Registrable Notes incurred in
     connection with the registration of the Registrable Notes. The Issuers and
     the Guarantor shall not have any obligation to pay any underwriting fees,
     discounts or commissions attributable to the sale of Registrable
     Securities.

 5.  Indemnification
 --  ---------------

        (a)     The Guarantor and each of the Issuers, jointly and severally,
     agree to indemnify and hold harmless each Holder of Registrable Notes and
     each Participating Broker-Dealer selling Exchange Notes during the
     Applicable Period, the officers and directors 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 and
     liabilities (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 Prospectus (as amended or
     supplemented if the Issuers and the Guarantor 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 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 and the
     Guarantor in writing by such Participant expressly for use therein;
     provided that the foregoing indemnity with respect to any preliminary
     --------
     Prospectus shall not inure to the benefit of any Participant (or to the
     benefit of an officer or director of such Participant or any Person
     controlling such Participant) from whom the Person asserting any such
     losses, claims, damages or liabilities purchased 
<PAGE>
 
                                      -29-

    Registrable Notes or Exchange Notes if such untrue statement or omission or
    alleged untrue statement or omission made in such preliminary Prospectus is
    eliminated or remedied in the related Prospectus (as amended or
    supplemented if the Issuers and the Guarantor shall have furnished any
    amendments or supplements thereto) and a copy of the related Prospectus (as
    so amended or supplemented) shall have been furnished to such Participant
    at or prior to the sale of such Registrable or Exchange Notes, as the case
    may be, to such Person.

        (b)     Each Participant will be required to agree, severally and not
    jointly, to indemnify and hold harmless the Guarantor and each Issuer, their
    directors and officers and each Person who controls any of the Issuers or
    the Guarantor within the meaning of Section 15 of the Securities Act or
    Section 20 of the Exchange Act to the same extent as the foregoing indemnity
    from the Guarantor and each Issuer to each Participant, but only with
    reference to information relating to such Participant furnished to the
    Guarantor and each Issuer 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 (b) 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 which indemnity may be sought pursuant to
    either paragraph (a) or (b) of this Section 7, such Person (the "Indemnified
    Person") shall promptly notify the Person against whom such indemnity may be
    sought (the "Indemnifying Person") in writing, and the Indemnifying Person,
    upon request of the Indemnified Person, shall retain one 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 incurred by such
    counsel related to such proceeding. In any such proceeding, any Indemnified
    Person shall have the right to retain its own counsel, but 
<PAGE>
 
                                      -30-

    the fees and expenses of such counsel shall be at the expense of such
    Indemnified Person unless (i) the Indemnifying Person and the Indemnified
    Person shall have mutually agreed in writing to the contrary, (ii) the
    Indemnifying Person has failed within a reasonable 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 the
    Indemnifying Person and the Indemnified Person and such Indemnified Person
    shall have been advised by counsel that there may be one or more legal
    defenses available to it which are different from or additional to those
    available to any such Indemnifying Person. It is understood that the
    Indemnifying Person shall not, in connection with any proceeding or related
    proceeding in the same jurisdiction, be liable for the fees and expenses of
    more than one separate law firm (in addition to any local counsel) for all
    Indemnified Persons, and that all such fees and expenses shall be reimbursed
    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 any such separate firm for
    the Issuers, the Guarantor, their respective directors, their respective
    officers and such control Persons of the Issuers and the Guarantor shall be
    designated in writing by the Issuers and the Guarantor. The Indemnifying
    Person shall not be liable for any settlement of any proceeding effected
    without its prior written consent, but if settled with such consent or if
    there be a final judgment for the plaintiff for which the Indemnified Person
    is entitled to indemnification pursuant to this Agreement, the Indemnifying
    Person agrees to indemnify any Indemnified Person from and against any loss
    or liability by reason of such settlement or judgment. Notwithstanding the
    foregoing sentence, if at any time an Indemnified Person shall have
    requested an Indemnifying Person to reimburse the Indemnified Person for
    reasonable fees and expenses incurred by counsel as contemplated by the
    third sentence of this paragraph, the Indemnifying Person agrees that it
    shall be liable for any settlement of any proceeding effected without its
    written consent if (i) such settlement is entered into more than 60 days
    after receipt by such Indemnifying Person of the aforesaid request and 
<PAGE>
 
                                      -31-

     (ii) such Indemnifying Person shall not have reimbursed the Indemnified
     Person in accordance with such request prior to the date of such
     settlement; provided, however, that the Indemnifying Person shall not be
                 --------  -------
     liable for any settlement effected without its consent pursuant to this
     sentence if the Indemnifying Party is contesting, in good faith, the
     request for reimbursement. No Indemnifying Person shall, without the prior
     written consent of the Indemnified Person, effect any settlement of any
     pending or threatened proceeding in respect of which any Indemnified Person
     is or could have been a party and indemnity could have been sought
     hereunder by such Indemnified Person, unless such settlement includes an
     unconditional release of such Indemnified Person from all liability on
     claims that are the subject matter of such proceeding.

        (d)     If the indemnification provided for in paragraphs (a) and (b) of
     this Section 7 is unavailable to an Indemnified Person or insufficient in
     respect of any losses, claims, damages or liabilities referred to therein,
     then each Indemnifying Person under such paragraphs, in lieu of
     indemnifying such Indemnified Person thereunder, 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 Issuers and the Guarantor on the one
     hand and the Participants on the other in connection with the statements or
     omissions that resulted in such losses, claims, damages or liabilities, as
     well as any other relevant equitable considerations. The relative fault of
     the Issuers and the Guarantor on the one hand and the Participants on the
     other 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 and the Guarantor or by the Participants and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such statement or omission.

        (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 
<PAGE>
 
                                      -32-

     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 the immediately preceding paragraph. The
     amount paid or payable by an Indemnified Person as a result of the losses,
     claims, damages and liabilities referred to in the immediately preceding
     paragraph 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 exceeds the amount of any damages that
     such Participant has otherwise been required to pay 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)     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.

6.  Rules 144 and 144A
- --  ------------------

        The Issuers and the Guarantor covenant that they will file the reports
required to be filed by them under the Securities Act and the Exchange Act and
the rules and regulations adopted by the SEC thereunder in a timely manner and,
if at any time the Issuers and the Guarantor are not required to file such
reports, they will, upon the request of any Holder of Registrable Notes, make
publicly available other information of a like nature so long as necessary to
permit sales pursuant to Rule 144 or Rule 144A.  The Issuers and the Guarantor
further covenant that so long as any Registrable Notes remain outstanding to
make available to any Holder of Registrable Notes in connection with any sale
thereof, the information required by Rule 144A(d)(4) under the Securities Act in
order to permit resales of such Registrable Notes 
<PAGE>
 
                                      -33-

pursuant to (a) such Rule 144A, or (b) any similar rule or regulation hereafter
adopted by the SEC.

7.  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
Holders of a majority in aggregate principal amount of such Registrable Notes
included in such offering and shall be reasonably acceptable to the Issuers and
the Guarantor.

        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 reasonably required under the terms
of such underwriting arrangements.

8.  Miscellaneous
- --  -------------

                (a)  Remedies. In the event of a breach by the Issuers, the
                ---  --------
Guarantor or their subsidiaries of any of their obligations under this
Agreement, other than the occurrence of an event which requires payment of
Additional Interest, each Holder of Registrable Notes, in addition to being
entitled to exercise all rights provided herein, in the Indenture or, in the
case of the Initial Purchaser, in the Restructuring Agreement or granted by law,
including recovery of damages, will be entitled to specific performance of its
rights under this Agreement. The Issuers and the Guarantor agree that monetary
damages would not be adequate compensation for any loss incurred by reason of a
breach by them of any of the provisions of this Agreement and hereby further
agree, jointly and severally, that, in the event of any action for specific
performance in respect of such breach, they shall waive the defense that a
remedy at law would be adequate.
<PAGE>
 
                                      -34-

                (b)  Enforcement. The Trustee shall be authorized to enforce the
                ---  -----------
     provisions of this Agreement for the ratable benefit of the Holders.

                (c)  No Inconsistent Agreements. The Issuers and the Guarantor
                ---  --------------------------
     have not, as of the date hereof, and the Issuers and the Guarantor 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 Issuers and the Guarantor have
     not entered and will not enter into any agreement with respect to any of
     their securities which will grant to any Person piggy-back rights with
     respect to a Registration Statement required to be filed under this
     Agreement.

                (d)  Adjustments Affecting Registrable Notes. The Issuers and
                ---  ---------------------------------------
     the Guarantor 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.

                (e)  Amendments and Waivers. The provisions of this Agreement,
                ---  ----------------------
     including the provisions of this sentence, may not be amended, modified or
     supplemented, and waivers or consents to departures from the provisions
     hereof may not be given, unless the Issuers and the Guarantor have obtained
     the written consent of Holders of at least a majority of the then
     outstanding aggregate principal amount of Registrable Notes.
     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 by such
     Holders pursuant to such Registration Statement, provided that the
                                                      --------
     provisions of this sentence may not be amended, modified or supplemented
<PAGE>
 
                                      -35-

     sentence.

indirectly guarantees Indebtedness of a third Person, the preceding sentence
shall give effect to the incurrence of such guaranteed Indebtedness as if such
Person or any Restricted Subsidiary of such Person had directly incurred or

                                                        ---------          
incorporated in and forms a part of this Indenture.  The Notes may have
notations, legends or endorsements required by law, rule or usage to which the
Issuers are subject.  Any such notations, legends or endorsements shall be
furnished to the Trustee in writing.  Without limiting the generality of the
foregoing, Notes offered and sold to Qualified Institutional Buyers in reliance
on Rule 144A ("Rule 144A Notes") shall bear the legend and include the form of
assignment set forth in Exhibit B, Notes offered and sold in offshore
                        ---------                                    
transactions in reliance on Regulation S ("Regulation S Notes") shall bear the
legend and include the form of assignment set forth in Exhibit C, and Notes
                                                       ---------           
offered and sold to Institutional Accredited Investors in transactions exempt
from registration under the Securities Act not made in reliance on Rule 144A or
Regulation S ("Other Notes") shall be represented by Physical Notes bearing the
Private Placement Legend.  Each Note shall be dated the date of its
authentication.

          The terms and provisions contained in the Notes shall constitute, and
are expressly made, a part of this Indenture and, to the extent applicable, the
Issuers and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and agree to be bound thereby.

          The Notes may be presented for registration of transfer and exchange
at the offices of the Registrar.

 Section 2.03. Execution and Authentication.
               ---------------------------- 

          Two Officers shall sign, or one Officer shall sign and one Officer
(each of whom shall, in each case, have been duly authorized by all requisite
corporate actions) shall attest to, the Notes for each of the Issuers by manual
or facsimile signature.

          If an Officer whose signature is on a Note was an Officer at the time
of such execution but no longer holds that 
<PAGE>
 
                                      -32-

office at the time the Trustee authenticates the Note, the Note shall be valid
nevertheless.

          No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any Note
shall be conclusive evidence, and the only evidence, that such Note has been
duly authenticated and delivered hereunder. Notwithstanding the foregoing, if
any Note shall have been authenticated and delivered hereunder but never issued
and sold by the Issuers, and the Issuers shall deliver such Note to the Trustee
for cancellation as provided in Section 2.12, for all purposes of this Indenture
such Note shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Issuers to authenticate the Notes. Unless otherwise provided in the
appointment, an authenticating agent may authenticate the Notes 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.
Each Paying Agent is designated as an authenticating agent for purposes of this
Indenture.

          The Notes shall be issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.

Section 2.04. Registrar and Paying Agent.
              -------------------------- 

          The Issuers shall maintain an office or agency (which shall be located
in the Borough of Manhattan in The City of New York, State of New York) where
Notes may be presented for registration of transfer or for exchange (the
"Registrar"), and an office or agency where Notes may be presented for payment
(the "Paying Agent") and an office or agency where notices and demands to or
upon the Issuers, if any, in respect of the Notes and this Indenture may be
served.  The Registrar shall keep a register of the Notes and of their transfer
and exchange.  The Issuers may have one or more additional Paying Agents.  The
term "Paying Agent" includes any additional Paying Agent.  Neither the Issuers
nor any Affiliate thereof may act as Paying Agent. The Issuers 
<PAGE>
 
                                      -33-

may change any Paying Agent or Registrar without notice to any Noteholder.

          The Issuers shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which shall incorporate the provisions of
the TIA.  The agreement shall implement the provisions of this Indenture that
relate to such Agent.  The Issuers shall notify the Trustee of the name and
address of any such Agent.  If the Issuers fail to maintain a Registrar or
Paying Agent, or fail to give the foregoing notice, the Trustee shall act as
such and shall be entitled to compensation in accordance with Section 7.07.

          The Issuers initially appoint the Trustee as Registrar, Paying Agent
and agent for service of notices and demands in connection with the Notes and
this Indenture.

Section 2.05. Paying Agent to Hold Money in Trust.
              ----------------------------------- 

          Each Paying Agent shall hold in trust for the benefit of the
Noteholders or the Trustee all money held by the Paying Agent for the payment of
principal of or premium or interest on the Notes (whether such money has been
paid to it by the Issuers or any other obligor on the Notes), and the Issuers
and the Paying Agent shall notify the Trustee of any Default by the Issuers (or
any other obligor on the Notes) in making any such payment.  Money held in trust
by the Paying Agent need not be segregated except as required by law and in no
event shall the Paying Agent be liable for any interest on any money received by
it hereunder.  The Issuers at any time may require the Paying Agent to pay all
money held by it to the Trustee and account for any funds disbursed and the
Trustee may at any time during the continuance of any Event of Default specified
in Section 6.01(1) or (2), upon written request to the Paying Agent, require
such Paying Agent to pay forthwith all money so held by it to the Trustee and to
account for any funds disbursed.  Upon making such payment, the Paying Agent
shall have no further liability for the money delivered to the Trustee.

Section 2.06. Noteholder 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
the Noteholders.  If the Trustee is not the Registrar, the Issuers shall furnish
to the Trustee at least five Business Days before each Interest Payment Date,
and 
<PAGE>
 
                                      -34-

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 the Noteholders.

Section 2.07. Transfer and Exchange.
              --------------------- 

          Subject to Sections 2.16 and 2.17, when Notes are presented to the
Registrar with a request from the Holder of such Notes to register a transfer or
to exchange them for an equal principal amount of Notes of other authorized
denominations, the Registrar shall register the transfer as requested if the
requirements of Section 8-401(a) of the New York Uniform Commercial Code are
met.  To permit registrations of transfers and exchanges, the Issuers shall
issue and execute and the Trustee shall authenticate new Notes evidencing such
transfer or exchange at the Registrar's request.  No service charge shall be
made to the Noteholder for any registration of transfer or exchange.  The
Registrar may require from the noteholder payment of a sum sufficient to cover
any transfer taxes or other governmental charge that may be imposed in relation
to a transfer or exchange, but this provision shall not apply to any exchange
pursuant to Section 2.11, 3.06, 4.10, 4.19 or 8.05 (in which events the Issuers
shall be responsible for the payment of such taxes).  The Registrar shall not be
required to exchange or register a transfer of any Note for a period of 15 days
immediately preceding the selection of Notes to be redeemed or any Note selected
for redemption.

          Any Holder of the Global Note shall, by acceptance of such Global
Note, agree that transfers of the beneficial interests in such Global Note may
be effected only through a book entry system maintained by the Holder of such
Global Note (or its agent), and that ownership of a beneficial interest in the
Global Note shall be required to be reflected in a book entry.

          Each Holder of a Note agrees to indemnify the Issuers and the Trustee
against any liability that may result from the transfer, exchange or assignment
of such Holder's Note in violation of any provision of this Indenture and/or
applicable U.S. Federal or state securities law.

          Except as expressly provided herein, neither the Trustee nor the
Registrar shall have any duty to monitor the Issuers' compliance with or have
any responsibility with respect to the Issuers' compliance with any Federal or
state securities laws.

                                      -35-

Section 2.08. Replacement Notes.
              ----------------- 

          If a mutilated Note is surrendered to the Registrar or the Trustee, or
if the Holder of a Note claims that the Note has been lost, destroyed or
wrongfully taken, the Issuers shall issue and the Trustee shall authenticate a
replacement Note if the Holder of such Note furnishes to the Issuers and the
Trustee evidence reasonably acceptable to them of the ownership and the
destruction, loss or theft of such Note and if the requirements of Section 8-405
of the New York Uniform Commercial Code are met. If required by the Trustee or
the Issuers, an indemnity bond shall be posted, sufficient in the judgment of
both to protect the Issuers, the Trustee or any Paying Agent from any loss that
any of them may suffer if such Note is replaced.  The Issuers may charge such
Holder for the Issuers' reasonable out-of-pocket expenses in replacing such Note
and the Trustee may charge the Issuers for the Trustee's expenses (including,
without limitation, attorneys' fees and disbursements) in replacing such Note.
Every replacement Note shall constitute an additional contractual obligation of
the Issuers.

Section 2.09. Outstanding Notes.
              ----------------- 

          The Notes outstanding at any time are all Notes that have been
authenticated by the Trustee except for (a) those canceled by it, (b) those
delivered to it for cancellation, (c) to the extent set forth in Sections 9.01
and 9.02, on or after the date on which the conditions set forth in Section 9.01
or 9.02 have been satisfied, those Notes theretofore authenticated and delivered
by the Trustee hereunder and (d) those described in this Section 2.09 as not
outstanding. Subject to Section 2.10, a Note does not cease to be outstanding
because an Issuer or one of its Affiliates holds the Note.

          If a Note is replaced pursuant to Section 2.08, it ceases to be
outstanding unless the Trustee receives written notice that the replaced Note is
held by a bona fide purchaser in whose hands such Note is a legal, valid and
binding obligation of the Issuers.

          If the Paying Agent holds, in its capacity as such, on any Maturity
Date or on any optional redemption date, money sufficient to pay all accrued
interest and principal with respect to the Notes payable on that date and is not
prohibited from paying such money to the Holders thereof pursuant to the terms
of 
<PAGE>
 
                                      -36-

this Indenture, then on and after that date such Notes cease to be outstanding
and interest on them ceases to accrue.

Section 2.10. Treasury Notes.
              -------------- 

          In determining whether the Holders of the required principal amount of
Notes have concurred in any declaration of acceleration or notice of Default or
direction, waiver or consent or any amendment, modification or other change to
this Indenture, Notes owned by an Issuer or any Affiliate of an Issuer shall be
disregarded as though they were not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
declaration, notice, direction, waiver or consent or any amendment, modification
or other change to this Indenture, only Notes as to which a Responsible Officer
of the Trustee has received an Officers' Certificate stating that such Notes are
so owned shall be so disregarded.  Notes so owned which have been pledged in
good faith shall not be disregarded if the pledgee establishes the pledgee's
right so to act with respect to the Notes and that the pledgee is not either of
the Issuers, any other obligor or guarantor on the Notes or any of their
respective Affiliates.

Section 2.11. Temporary Notes.
              --------------- 

          Until definitive Notes are prepared and ready for delivery, the
Issuers may prepare and the Trustee shall authenticate temporary Notes.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Issuers consider appropriate for temporary Notes.
Without unreasonable delay, the Issuers shall prepare and the Trustee shall
authenticate definitive Notes in exchange for temporary Notes.  Until such
exchange, temporary Notes shall be entitled to the same rights, benefits and
privileges as definitive Notes.

Section 2.12. Cancellation.
              ------------ 

          The Issuers at any time may deliver Notes to the Trustee for
cancellation.  The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and shall (subject to the record-
retention requirements of the Exchange Act) dispose of cancelled Notes in
accordance with its standard disposition 
<PAGE>
 
                                      -37-

policies in effect at the time. The Issuers may not reissue or resell, or issue
new Notes to replace, Notes that the Issuers have redeemed or paid, or that have
been delivered to the Trustee for cancellation.

Section 2.13. Defaulted Interest.
              ------------------ 

          If the Issuers default on a payment of interest on the Notes, they
shall pay the defaulted interest, plus (to the extent permitted by law) any
interest payable on the defaulted interest, in accordance with the terms hereof,
to the Persons who are noteholders on a subsequent special record date, which
date shall be at least five Business Days prior to the payment date.  The
Issuers shall fix such special record date and payment date and provide the
Trustee at least 20 days notice of the proposed amount of defaulted interest to
be paid and the special payment date and at the same time the Issuers shall
deposit with the Trustee the aggregate amount proposed to be paid in respect of
such defaulted interest.  At least 15 days before such special record date, the
Issuers shall mail to each noteholder a notice that states the special record
date, the payment date and the amount of defaulted interest, and interest
payable on defaulted interest, if any, to be paid.  The Issuers may make payment
of any defaulted interest in any other lawful manner not inconsistent with the
requirements (if applicable) of any securities exchange on which the Notes may
be listed and, upon such notice as may be required by such exchange, if, after
written notice given by the Issuers to the Trustee of the proposed payment
pursuant to this sentence, such manner of payment shall be deemed practicable by
the Trustee.

Section 2.14. CUSIP Number.
              ------------ 

          The Issuers in issuing the Notes may use a "CUSIP" number, and if so,
such CUSIP number shall be included 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 number
printed in the notice or on the Notes, and that reliance may be placed only on
the other identification numbers printed on the Notes.  The Issuers shall
promptly notify the Trustee of any such CUSIP number used by the Issuers in
connection with the issuance of the Notes and of any change in the CUSIP number.

Section 2.15. Deposit of Moneys.
              ----------------- 
<PAGE>
 
                                      -38-

          Prior to 10:00 a.m., New York City time, on each Interest Payment Date
and Maturity Date, the Issuers shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date or Maturity Date, as the case may be, in a timely
manner which permits the Trustee to remit payment to the Holders on such
Interest Payment Date or Maturity Date, as the case may be.  The principal and
interest on Global Notes shall be payable to the Depository or its nominee, as
the case may be, as the sole registered owner and the sole holder of the Global
Notes represented thereby.  The principal and interest on Physical Notes shall
be payable at the office of the Paying Agent.

Section 2.16.  Book-Entry Provisions for Global Notes.
               -------------------------------------- 

          (a)  Rule 144A Notes initially shall be represented by one or more
notes in registered, global form without interest coupons (collectively, the
"Restricted Global Note").  Regulation S Notes initially shall be represented by
one or more notes in registered, global form without interest coupons
(collectively, the "Regulation S Global Note," and, together with the Restricted
Global Note and any other global notes representing Notes, the "Global Notes").
The Global Notes shall bear legends as set forth in Exhibit D.  The Global Notes
                                                    ---------                   
initially shall (i) be registered in the name of the Depository or the nominee
of such Depository, in each case for credit to an account of an Agent Member
(or, in the case of the Regulation S Global Notes, of Euroclear System
("Euroclear") and Cedel Bank, S.A. ("CEDEL")), (ii) be delivered to the Trustee
as custodian for such Depository and (iii) bear legends as set forth in Exhibit
                                                                        -------
B with respect to Restricted Global Notes and Exhibit C with respect to
- -                                             ---------                
Regulation S Global Notes.

          Members of, or direct or indirect participants in, the Depository
("Agent Members") shall have no rights under this Indenture with respect to any
Global Note held on their behalf by the Depository, or the Trustee as its
custodian, or under the Global Notes, and the Depository may be treated by the
Issuers, the Trustee and any agent of the Issuers or the Trustee as the absolute
owner of the Global Note for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Trustee or any agent of the Issuers
or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a Holder of any Note.
<PAGE>
 
                                      -39-

          (b)  Transfers of Global Notes shall be limited to transfer in whole,
but not in part, to the Depository, its successors or their respective nominees.
Interests of beneficial owners in the Global Notes may be transferred or
exchanged for Physical Notes in accordance with the rules and procedures of the
Depository and the provisions of Section 2.17.  In addition, a Global Note shall
be exchangeable for Physical Notes if (i) the Depository (x) notifies the
Issuers that it is unwilling or unable to continue as depository for such Global
Note and the Issuers thereupon fail to appoint a successor depository or (y) has
ceased to be a clearing agency registered under the Exchange Act, (ii) the
Issuers, at their option, notify the Trustee in writing that they elect to cause
the issuance of such Physical Notes or (iii) there shall have occurred and be
continuing a Default or an Event of Default with respect to the Notes.  In all
cases, Physical Notes delivered in exchange for any Global Note or beneficial
interests therein shall be registered in the names, and issued in any approved
denominations, requested by or on behalf of the Depository (in accordance with
its customary procedures).

          (c)  In connection with any transfer or exchange of a portion of the
beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Issuers
shall execute, and the Trustee shall authenticate and make available for
delivery, one or more Physical Notes of like tenor and amount.

          (d)  In connection with the transfer of Global Notes as an entirety to
beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to
be surrendered to the Trustee for cancellation, and the Issuers shall execute,
and the Trustee shall authenticate and deliver, to each beneficial owner
identified by the Depository in writing in exchange for its beneficial interest
in the Global Notes, an equal aggregate principal amount of Physical Notes of
authorized denominations.

          (e)  Any Physical Note constituting a Rule 144A Note delivered in
exchange for an interest in a Global Note pursuant to paragraph (b), (c) or (d)
shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section
2.17, bear the Private Placement Legend or, in the case of the Regulation S
Global Note, 
<PAGE>
 
                                      -40-

the legend set forth in Exhibit C, in each case, unless the Issuers determine
                        ---------
otherwise in compliance with applicable law.

          (f)  On or prior to the 40th day after the later of the commencement
of the offering of the Notes represented by a Regulation S Global Note and the
original issue date of such Notes (such period through and including such 40th
day, the "Restricted Period"), a beneficial interest in the Regulation S Global
Note may be held only through Euroclear or CEDEL, as indirect participants in
DTC, unless transferred to a Person who takes delivery in the form of an
interest in the corresponding Restricted Global Note, only upon receipt by the
Trustee of a written certification from the transferor to the effect that such
transfer is being made (i)(a) to a Person who the transferor reasonably believes
is a Qualified Institutional Buyer in a transaction meeting the requirements of
Rule 144A or (b) pursuant to another exemption from the registration
requirements under the Securities Act which is accompanied by an Opinion of
Counsel regarding the availability of such exemption and (ii) in accordance with
all applicable securities laws of any state of the United States or any other
jurisdiction.

          (g)  Beneficial interests in the Restricted Global Note may be
transferred to a Person who takes delivery in the form of an interest in the
Regulation S Global Note, whether before or after the expiration of the
Restricted Period, only if the transferor first delivers to the Trustee a
written certificate to the effect that such transfer is being made in accordance
with Rule 903 or 904 of Regulation S or Rule 144 (if available) and that, if
such transfer occurs prior to the expiration of the Restricted Period, the
interest transferred will be held immediately thereafter through Euroclear or
CEDEL.

          (h)  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 shall, upon transfer, cease to be an interest in such Global Note
and become an interest in such other Global Note and, accordingly, shall
thereafter be subject to all transfer restrictions and other procedures
applicable to beneficial interests in such other Global Note for as long as it
remains such an interest.

          (i)  The Holder of any Global Note may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests through Agent Members, to take 
<PAGE>
 
                                      -41-

any action which a Holder is entitled to take under this Indenture or the Notes.

Section 2.17. Special Transfer Provisions.
              --------------------------- 

          (a)  Transfers to Non-QIB Institutional Accredited Investors and Non-
               ---------------------------------------------------------------
U.S. Persons.  The following provisions shall apply with respect to the

any Institutional Accredited Investor which is not a QIB or to any Non-U.S.
Person:

          (i)  the Registrar shall register the transfer of any Note
     constituting a Rule 144A Note, whether or not such Note bears the Private
     Placement Legend, if (x) the requested transfer is after August 15, 1999 or
     such other date as such Note shall be freely transferable under Rule 144 as
     certified in an Officer's Certificate or (y) (1) in the case of a transfer
     to an Institutional Accredited Investor which is not a QIB (excluding Non-
     U.S. Persons), the proposed transferee has delivered to the Registrar a

                                              ---------
     case of a transfer to a Non-U.S. Person (including a QIB), the proposed
     transferor has delivered to the Registrar a certificate substantially in
     the form of Exhibit F hereto; provided that in the case of a transfer of a
                 ---------         --------
     Note bearing the Private Placement Legend for a Note not bearing the
     Private Placement Legend, the Registrar has received an Officers'
     Certificate authorizing such transfer; and

          (ii) if the proposed transferor is an Agent Member holding a
     beneficial interest in a Global Note, upon receipt by the Registrar of (x)
     the certificate, if any, required by paragraph (i) above and (y)
     instructions given in accordance with the Depository's and the Registrar's
     procedures,

whereupon (a) the Registrar shall reflect on its books and records the date and
(if the transfer does not involve a transfer of outstanding Physical Notes) a
decrease in the principal amount of a Global Note in an amount equal to the
principal amount of the beneficial interest in a Global Note to be transferred,
and (b) the Registrar shall reflect on its books and records the date and an
increase in the principal amount of a Global Note in an amount equal to the
principal amount of the beneficial interest in the Global Note transferred or
the Issuers shall execute and the Trustee shall authenticate and make available
for delivery one or more Physical Notes of like tenor and amount.

                                      -42-

          (b)  Transfers to QIBs.  The following provisions shall apply with
               -----------------                                            
respect to the registration of any proposed registration of transfer of a Note

               Redeemed.
               ---------

          In the event that fewer than all of the Notes are to be redeemed, the
Trustee shall select the Notes to be redeemed, if the Notes are listed on a
national securities exchange, in accordance with the rules of such exchange or,
if the Notes are not so listed, either on a pro rata basis or by lot, or such

notify the Issuers of the Notes selected for redemption and, in the case of any
Notes selected for partial redemption, the principal amount thereof to be
redeemed.  The Trustee may select for redemption portions of the principal of
the Notes that have denominations larger than $1,000.  Notes and portions
thereof the Trustee selects shall be redeemed in amounts of $1,000 or whole
multiples of $1,000.  For all purposes of this Indenture unless the context
otherwise requires, provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption.

Section 3.03.  Notice of Redemption.
               -------------------- 

          At least 30 days, and no more than 60 days, before a Redemption Date,

the same appears on the registry books maintained by the Registrar pursuant to
Section 2.03 hereof.

and upon surrender of
<PAGE>
 
                                      -45-

such Note, a new Note or Notes in principal amount equal to the unredeemed
portion will be issued;

          (4) the name and address of the Paying Agent;

          (5) that Notes called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

          (6) that unless the Issuers Default in making the redemption payment,
interest on Notes called for redemption ceases to accrue on and after the
Redemption Date;

          (7) the provision of paragraph 5 of the Notes pursuant to which the
Notes called for redemption are being redeemed; and

          (8) the aggregate principal amount of Notes that are being redeemed.

          At the Issuers' written request made at least five Business Days prior

redemption in the Issuers' name and at the Issuers' sole expense.

Section 3.04.  Effect of Notice of Redemption.
               ------------------------------ 

          Once the notice of redemption described in Section 3.03 is mailed,
Notes called for redemption become due and payable on the Redemption Date and at
the redemption price, including any premium, plus interest accrued to the
Redemption Date.  Upon surrender to the Paying Agent, such Notes shall be paid
at the redemption price, including any premium, plus interest accrued to the
Redemption Date, provided that if the Redemption Date is after a regular record
                 --------                                                      
date and on or prior to the Interest Payment Date, the accrued interest shall be
payable to the Holder of the redeemed Notes registered on the relevant record
date, and provided, further, that if a Redemption Date is a Legal Holiday,
          --------  -------                                               
payment shall be made on the next succeeding Business Day and no interest shall
accrue for the period from such Redemption Date to such succeeding Business Day.

Section 3.05.  Deposit of Redemption Price.
               --------------------------- 

          On or prior to 10:00 a.m., New York City time, on each Redemption

funds money sufficient to pay the

redemption price of and accrued interest on all Notes to be redeemed on that
date other than Notes or portions thereof called for redemption on that date
which have been delivered by the Issuers to the Trustee for cancellation.

          On and after any Redemption Date, if money sufficient to pay the
redemption price of and accrued interest on Notes called for redemption shall
have been made available in accordance with the preceding paragraph, the Notes
called for redemption will cease to accrue interest and the only right of the
Holders of such Notes will be to receive payment of the redemption price of and,
subject to the first proviso in Section 3.04, accrued and unpaid interest on
such Notes to the Redemption Date.  If any Note surrendered for redemption shall
not be so paid because money sufficient to pay the redemption price shall not
have been made available, interest will be paid, from the Redemption Date until
such redemption payment is made, on the unpaid principal of the Note and any
interest not paid on such unpaid principal, in each case, at the rate and in the
manner provided in the Notes.

Section 3.06. Notes Redeemed in Part.
              ---------------------- 

          Upon surrender of a Note that is redeemed in part, the Trustee shall

portion of the Note surrendered.

comply with the provisions of TIA (S) 314(a).  Delivery of such reports,
information and documents to the Trustee is for informational purposes only and
the Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained

required to furnish such reports and other information referred to in paragraph

extension law or any usury law or other law which would prohibit or forgive the
Issuers from paying all or any portion of the principal of, premium, if any,
and/or interest on the Notes 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 they may lawfully do so)

          The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, directly or indirectly, incur any Indebtedness (including
Acquired 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 such Indebtedness, Insight Ohio or any of the Issuers' Restricted
Subsidiaries may incur Indebtedness (including Acquired Indebtedness) if after
giving effect to the incurrence of such Indebtedness and the receipt and
application of the proceeds thereof, the Consolidated Leverage Ratio of the
Issuers is less than 7 to 1.

          Notwithstanding the foregoing, Insight Ohio and the Issuers'
Restricted Subsidiaries may incur Permitted Indebtedness; provided that such

terms (or by the terms of any agreement governing such Indebtedness) is
subordinated in right of payment to any other Indebtedness of the Issuers or
such Restricted Subsidiary unless such Indebtedness is also by its terms (or by
the terms of any agreement governing such Indebtedness) made expressly
subordinate in right of payment to the Notes or the Guarantee of such Guarantor,
as the case may be, pursuant to subordination provisions that are substantively
identical to the subordination provisions of such Indebtedness (or such
agreement) that are most favorable to the holders of any other Indebtedness of
the Issuers or such Restricted Subsidiary, as the case may be.

          For purposes of determining compliance with this covenant, in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Indebtedness or is entitled to be incurred pursuant to
the first paragraph of this Section 4.06, the Issuers shall, in their sole
discretion, classify such item of Indebtedness in any manner that complies with
this covenant and such item of Indebtedness shall be treated as having been

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

          The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Issuer or such
applicable Restricted Subsidiary, as the case may be, receives consideration at
the time of such sale or other disposition at least equal to the fair market
value of the assets sold or otherwise disposed of; (ii) not less than 80% of the
consideration received by an Issuer or such applicable Restricted Subsidiary, as
the case may be, is in the form of cash or Cash Equivalents; provided, however,
                                                             --------  ------- 
that the amount of any (x) Indebtedness of an Issuer or any Restricted
Subsidiary that is actually assumed by the transferee in such Asset Sale and
from which an Issuer and the Restricted Subsidiaries are fully released shall be
deemed to be cash for purposes of determining the percentage of cash
consideration received by an Issuer or the Restricted Subsidiaries and (y) notes
or other similar obligations received by an Issuer or the Restricted
Subsidiaries from such transferee that are immediately converted, sold or
exchanged (or are converted, sold or exchanged within 30 days of the related
Asset Sale) by an Issuer or the Restricted Subsidiaries into cash shall be

                                     -54-

Issuer or such Restricted Subsidiary are applied (a) to the extent an Issuer or
any such Restricted Subsidiary, as the case may be, elects, or is required, to
prepay, repay or purchase indebtedness under the Senior Credit Facility within
180 days following the receipt of the Asset Sale Proceeds from any Asset Sale;
provided that any such repayment shall result in a permanent reduction of the
- --------
commitments thereunder (other than commitments under a revolving credit
facility) in an amount equal to the principal amount so repaid; or (b) to the
extent of the balance of Asset Sale Proceeds, after application, if any, as
described above, to the extent the Issuers elect, on a pro rata basis to the
                                                       --- ----
repayment of an amount of Other Pari Passu Debt not exceeding the Other Pari
Passu Debt Pro Rata Share (provided that any such repayment shall result in a
                           --------
permanent reduction of any commitment in respect thereof in an amount equal to
the principal amount so repaid) within 180 days following the receipt of the
Asset Sale Proceeds from any Asset Sale; or (c) to the extent of the balance of
Asset Sale Proceeds after application as described above, to the extent the
Issuers or a Restricted Subsidiary elect, to an investment in assets (including
Capital Stock or other securities purchased in connection with the acquisition
of Capital Stock or property of another Person) used or useful in businesses
similar, ancillary, complementary or otherwise related to the business of an
Issuer or any such Restricted Subsidiary as then conducted; provided that (1)
                                                            --------
such investment occurs or an Issuer or any such Restricted Subsidiary enters
into contractual commitments to make such investment, subject only to customary
conditions (other than the obtaining of financing), within 180 days following
receipt of such Asset Sale Proceeds and (2) Asset Sale Proceeds so contractually
committed are so applied within 270 days following the receipt of such Asset
Sale Proceeds; and (d) if on such 180th day in the case of clauses (iii)(a),
(iii)(b) and (iii)(c)(1) or on such 270th day in the case of clause (iii)(c)(2)
with respect to any Asset Sale, the Available Asset Sale Proceeds exceed $10.0
million, the Issuers shall apply an amount equal to the Available Asset Sale
Proceeds to an offer to repurchase the Senior Notes, at a purchase price in cash
equal to 100% of the principal amount thereof plus accrued and unpaid interest,
if any, to the purchase date (an "Excess Proceeds Offer"). If an Excess Proceeds
Offer is not fully subscribed, the Issuers may retain the portion of the
Available Asset Sale Proceeds not required to repurchase Notes.

          If the Issuers are required to make an Excess Proceeds Offer, the
Issuers shall mail, within 30 days following the date 
<PAGE>
 
                                     -55-

specified in clause (iii)(d) above, a notice to the holders stating, among other
things: (1) that such holders have the right to require the Issuers to apply the
Available Asset Sale Proceeds to repurchase such Notes at a purchase price in
cash equal to 100% of the principal amount thereof plus accrued and unpaid
interest, if any, to the purchase date; (2) the purchase date, which shall be no
earlier than 30 days and not later than 45 days from the date such notice is
mailed; (3) the instructions that each holder must follow in order to have such
Notes purchased; and (4) the calculations used in determining the amount of
Available Asset Sale Proceeds to be applied to the purchase of such Notes.

          In the event of the transfer of substantially all of the property and
assets of the Issuers and their Restricted Subsidiaries as an entirety to a
Person in a transaction permitted under Section 5.01 hereof, the successor
Person shall be deemed to have sold the properties and assets of the Issuers and
their Restricted Subsidiaries not so transferred for purposes of this Section
4.10, and shall comply with the provisions of this Section 4.10 with respect to
such deemed sale as if it were an Asset Sale.

          The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and other securities laws and regulations thereunder to the extent
such laws and regulations are applicable in connection with the repurchase of
Notes pursuant to an Excess Proceeds Offer. To the extent that the provisions of
any securities laws or regulations conflict with the "Asset Sale" provisions of
this Indenture, the Issuers shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached their obligations under the
"Asset Sale" provisions of this Indenture by virtue thereof.

Section 4.11. Limitation on Transactions with Affiliates.
              ------------------------------------------ 

          The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, directly or indirectly, enter into or suffer to exist any
transaction or series of related transactions (including, without limitation,
the sale, purchase, exchange or lease of assets, property or services) with any
Affiliate (each an "Affiliate Transaction") or extend, renew, waive or otherwise
modify in any material respect the terms of any Affiliate Transaction entered
into prior to the Issue Date unless (i) such Affiliate Transaction is between or
among the Issuers, or an Issuer and a Restricted Subsidiary of an Issuer; or
(ii) the 
<PAGE>
 
                                     -56-

terms of such Affiliate Transaction are fair and reasonable to an Issuer or such
Restricted Subsidiary, as the case may be, and the terms of such Affiliate
Transaction are substantially similar to the terms which could reasonably be
expected to be obtained by an Issuer or such Restricted Subsidiary, as the case
may be, in a comparable transaction made on an arm's-length basis between
unaffiliated parties. In any Affiliate Transaction (or any series of related
Affiliate Transactions which are similar or part of a common plan) involving an
amount or having a fair market value in excess of $3.0 million which is not
permitted under clause (i) above, an Issuer must obtain a resolution of the
Board of Directors of such Issuer certifying that such Affiliate Transaction
complies with clause (ii) above. In any Affiliate Transaction (or any series of
related Affiliate Transactions which are similar or part of a common plan)
involving an amount or having a fair market value in excess of $5.0 million
which is not permitted under clause (i) above, the Issuers must obtain a
favorable written opinion as to the fairness, from a financial point of view, of
such transaction or transactions, as the case may be, from an Independent
Financial Advisor.

          The foregoing provisions will not apply to (i) any Restricted Payment
that is not prohibited by the provisions described under Section 4.09 hereof,
(ii) reasonable fees and compensation paid to and indemnity provided on behalf
of, officers, directors or employees of the Issuers or any Restricted Subsidiary
of an Issuer as determined in good faith by such Issuer's Board of Directors or
senior management, (iii) arrangements now or hereafter in effect between Insight
and third parties which arrangements can be used for the benefit of a Restricted
Subsidiary and (iv) any forgiveness or distribution by Phoenix of the Excluded
Assets.

          Notwithstanding anything contained herein to the contrary, the terms
of the Operating Agreement and the indemnification provisions of the Close
Corporation Agreement and the performance by any party thereto of its
obligations thereunder shall not be considered an Affiliate Transaction.

Section 4.12. Limitations on Liens.
              -------------------- 

          The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, create, incur or otherwise cause or suffer to exist or become
effective any Liens of any kind (other than Permitted Liens) upon any property
or asset of an Issuer or any of their Restricted Subsidiaries or any shares of
Capital 
<PAGE>
 
                                     -57-

Stock or Indebtedness of any Restricted Subsidiary of an Issuer which owns
property or assets, now owned or hereafter acquired, unless (i) if such Lien
secures Indebtedness which is pari passu with the Notes (without giving effect
                              ---- -----
to the principles of structural subordination), then the Notes are secured on an
equal and ratable basis with the obligations so secured until such time as such
obligation is no longer secured by a Lien or (ii) if such Lien secures
Indebtedness which is subordinated to any debt of a Restricted Subsidiary, any
such Lien shall be subordinated to the Lien granted to the holders of the Notes
to the same extent as such Indebtedness is subordinated to the Notes.

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

their Restricted Subsidiaries to create or acquire, any Subsidiary other than
(i) a Restricted Subsidiary existing as of the Issue Date, or (ii) a Restricted
Subsidiary that is acquired or created in connection with the acquisition by an
Issuer of a related business or asset, or (iii) an Unrestricted Subsidiary;
provided, however, that each Restricted Subsidiary acquired or created pursuant
- --------  -------
to clause (ii) shall have executed a guarantee, satisfactory in form and
substance to the Trustee (and with such documentation relating thereto as the
Trustee shall require, including, without limitation a supplement or amendment
to this Indenture and opinions of counsel as to the enforceability of such
guarantee), pursuant to which such Restricted Subsidiary will become a
Guarantor. As of the Issue Date, the Issuers have no Restricted Subsidiaries,
other than Insight Ohio.

Section 4.16. Limitation on Sale and Lease-Back Transactions.
              ----------------------------------------------

          The Issuers will not, and will not permit any of their Restricted
Subsidiaries to, enter into any Sale and Lease-Back Transaction unless (i) the
consideration received in such Sale and Lease-Back Transaction is at least equal
to the fair market value of the property sold, as determined, in good faith, by
the Board of Directors of an Issuer and evidenced by a board resolution and (ii)
the Issuers could incur the Attributable 
<PAGE>
 
                                     -58-

Indebtedness in respect of such Sale and Lease-Back Transaction in compliance
with Section 4.06 hereof.

Section 4.17. Payments for Consent.
              -------------------- 

          The Issuers will not, and will not permit any of their Subsidiaries

by way of interest, fee or otherwise, to any holder of any Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Notes unless such consideration is offered to be paid
or agreed to be paid to all holders of the Notes which so consent, waive or
agree to amend in the time frame set forth in solicitation documents relating to
such consent, waiver or agreement.

Section 4.18. Legal Existence.
              --------------- 

          Subject to Article 5 hereof, the Issuers shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) their
legal existence, and the corporate, partnership or other existence of each
Restricted Subsidiary, in accordance with the respective organizational
documents (as the same may be amended from time to time) of each Restricted
Subsidiary and the rights (charter and statutory), licenses and franchises of
the Issuers and their Restricted Subsidiaries; provided, however, that the
                                               --------  -------
Issuers shall not be required to preserve any such right, license or franchise,
or the corporate, partnership, limited liability company or other existence of
any of their Restricted Subsidiaries if the Board of Directors of the Issuers
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Issuers and their Restricted Subsidiaries, taken
as a whole, and that the loss thereof is not adverse in any material respect to
the Holders.

          Within 20 days of the occurrence of a Change of Control, the Issuers
shall (i) cause a notice of the Change of Control Offer to be sent at least once

States and (ii) send by first-class mail, postage prepaid, to the Trustee and to
each holder of the Notes, at the address appearing in the register maintained by

     Payment Date;

          (6) that holders will be entitled to withdraw their acceptance if the
     Paying Agent receives, not later than the close of business on the third
     Business Day preceding 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 Notes delivered for purchase, and a

Stock, and an Issuer or such Restricted Subsidiary is required to make a Change
of Control Offer or to make a distribution with respect to such indebtedness or
Preferred Stock in the event of a change of control, the Issuers shall not
consummate any such offer or distribution with respect to such indebtedness or
Preferred Stock until such time as the Issuers shall have paid the Change of

Issuers' change of control offer and shall otherwise have consummated the change
of control offer made to holders of the Notes; and the Issuers will not issue
Indebtedness that is subordinated in right of payment to the Notes or Preferred
Stock with change of control provisions requiring the payment of such
Indebtedness or Preferred Stock prior to the payment of the Notes in the event
of a Change in Control under this Indenture.

          The Issuers will not be required to make a Change of Control Offer if
a third party makes the Change of Control Offer in the manner, at the time and
otherwise in compliance with the requirements set forth in this Indenture

     The Trustee may withhold notice to the holders of the Notes of any Default
(except in payment of principal or premium, if any, or interest on the Notes) if
the Trustee considers it to be in the best interest of the holders of the Notes
to do so.

Section 6.02.    Acceleration.
                 ------------ 

     If an Event of Default (other than an Event of Default resulting from
certain events of bankruptcy, insolvency or reorganization) shall have occurred
and be continuing, then the Trustee or the holders as directed by not less than
25% in aggregate principal amount of the Notes then outstanding may declare to
be immediately due and payable the entire principal amount of all the Notes then
outstanding plus accrued interest to the date of acceleration (i) and the same
shall become immediately due and payable or (ii) if there are any amounts
outstanding under the Senior Credit Facility, shall become immediately due and
payable upon the first to occur of an acceleration under the Senior Credit
Facility or 5 business days after receipt by an Issuer and the representative
under the Senior Credit Facility of a notice of acceleration; provided, however,
                                                              --------  ------- 
that after such acceleration but before a judgment or decree based on
acceleration is obtained by the Trustee, the holders of a majority in aggregate
principal amount of outstanding Notes may, under certain circumstances, rescind
and annul such acceleration if (i) all Events of Default, other than nonpayment
of principal, premium, if any, or interest that has become due solely because of
the acceleration, have been cured or waived as provided in this Indenture, (ii)
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, (iii) if the Issuers
have paid the Trustee its reasonable compensation and reimbursed the Trustee for
its expenses, disbursements and advances and (iv) in the event of the cure or
waiver of an Event of Default of the type described in clauses (6) or (7) of
Section 6.01, the Trustee shall have received an Officers' Certificate 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.  In case an Event of Default resulting from certain events of
bankruptcy, insolvency or reorganization shall occur, the principal, premium and
interest amount with respect to all of the Notes shall be due and payable
immediately without any declaration or other act on the part of the Trustee or
the holders of the Notes.
<PAGE>
 
                                      -71-

     The holders of a majority in principal amount of the Notes then outstanding
shall have the right to waive any existing Default or compliance with any
provision of this Indenture or the Notes and to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee,
subject to certain limitations provided for in this Indenture and under the TIA.

     No holder of any Note will have any right to institute any proceeding with
respect to this Indenture or for any remedy thereunder, unless such holder shall
have previously given to the Trustee written notice of a continuing Event of
Default and unless the holders of at least 25% in aggregate principal amount of
the outstanding Notes shall have made written request and offered reasonable
indemnity to the Trustee to institute such proceeding as Trustee, and unless the
Trustee shall not have received from the holders of a majority in aggregate
principal amount of the outstanding Notes a direction inconsistent with such
request and shall have failed to institute such proceeding within 60 days.
Notwithstanding the foregoing, such limitations do not apply to a suit
instituted on such Note on or after the respective due dates expressed in such
Note.

     Upon the occurrence and during the continuance of an Event of Default, the
Trustee shall enforce its remedies with respect to the pledged Senior Notes
Collateral in accordance with instructions received from holders of a majority
of the aggregate principal amount at maturity of outstanding Notes or, in the
absence of such instructions, in such manner as the Trustee deems appropriate,
in each case as provided herein.  All funds received by the Trustee upon any
such enforcement shall be distributed by the Trustee in accordance with the
provisions hereof.  Upon the full and final payment and performance of all
obligations of the Issuers under this Indenture and the Notes, the Senior Notes
Collateral shall be released.

Section 6.03.     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 premium, if any, and interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture and may take any
necessary action requested of it as Trustee to settle, compromise, adjust or
otherwise conclude any proceedings to which it is a party.
<PAGE>
 
                                      -72-

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Noteholder 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.

Section 6.04.    Waiver of Past Defaults and Events of
                 Default.
                 --------

     Subject to Sections 6.02, 6.07 and 8.02 hereof, the Holders of a majority
in principal amount of the Notes then outstanding have the right to waive any
existing Default or Event of Default or compliance with any provision of this
Indenture or the Notes.  Upon any such waiver, such Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been
cured for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereto.

Section 6.05.    Control by Majority.
                 ------------------- 

     The Holders of a majority in principal amount of the Notes then outstanding
may direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee by this Indenture.  The Trustee, however, may refuse to follow any
direction that conflicts with law or this Indenture or that the Trustee
determines may be unduly prejudicial to the rights of another Noteholder not
taking part in such direction, and the Trustee shall have the right to decline
to follow any such direction if the Trustee, being advised by counsel,
determines that the action so directed may not lawfully be taken or if the
Trustee in good faith shall, by a Responsible Officer, determine that the
proceedings so directed may involve it in personal liability; provided that the
                                                              --------         
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

Section 6.06.    Limitation on Suits.
                 ------------------- 

     Subject to Section 6.07 below, a Noteholder may not institute any
proceeding or pursue any remedy with respect to this Indenture or the Notes
unless:
<PAGE>
 
                                      -73-

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

          (2) the Holders of at least 25% in aggregate principal amount of the
     Notes then outstanding 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 reasonably satisfactory to the Trustee against any loss,
     liability or expense;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer, and, if requested provision, of
     indemnity; and

          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60 day period by the Holders of a majority in
     aggregate principal amount of the Notes then outstanding.

          A Noteholder may not use this Indenture to prejudice the rights of
another Noteholder or to obtain a preference or priority over another
Noteholder.

Section 6.07.   Rights of Holders to Receive Payment.
                ------------------------------------ 

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal of, or premium, if any, and
interest of the Note (including Additional Interest) on or after the respective
due dates expressed in the Note, or to bring suit for the enforcement of any
such payment on or after such respective dates, is absolute and unconditional
and shall not be impaired or affected without the consent of the Holder.

Section 6.08.   Collection Suit by Trustee.
                -------------------------- 

          If an Event of Default in payment of principal, premium or interest
specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against
the Issuers or the Guarantors (pursuant to the terms of Section 10) (or any
other obligor on the Notes) for the whole amount of unpaid principal and accrued
interest 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 set forth in the Notes, and
<PAGE>
 
                                      -74-

such further amounts 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 6.09.   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
Noteholders allowed in any judicial proceedings relative to the Issuers or the
Guarantors (or any other obligor upon the Notes), its creditors or its property
and shall be entitled and empowered to collect and receive any monies or other
property payable or deliverable on any such claims and to distribute the same
after deduction of its charges and expenses to the extent that any such charges
and expenses are not paid out of the estate in any such proceedings and any
custodian in any such judicial proceeding is hereby authorized by each
noteholder 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
Noteholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Noteholder any plan
or reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Noteholder in any such proceedings.

Section 6.10.   Priorities.
                ---------- 

          If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:

          FIRST:  to the Trustee for amounts due under Section 7.07 hereof;

          SECOND: to Noteholders for amounts due and unpaid on the Notes for
     principal, premium, if any, and interest (including Additional Interest, if
     any) as to each, ratably,
<PAGE>
 
                                      -75-

     without preference or priority of any kind, according to the amounts due
     and payable on the Notes; and

          THIRD:  to the Issuers or, to the extent the Trustee collects any
     amount from any Guarantor, to such Guarantor.

          The Trustee may fix a record date and payment date for any payment to
Noteholders 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 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 6.07 hereof or a suit by Holders of more than 10% in
principal amount of the Notes then outstanding.

Section 6.12.   Restoration of Rights and Remedies.
                ---------------------------------- 

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every case, subject to any
determination in such proceeding, the Issuers, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                                    TRUSTEE


Section 7.01.   Duties of Trustee.
                ----------------- 

          (a)   If an Event of Default actually known to a Responsible Officer
of the Trustee has occurred and is 
<PAGE>
 
                                      -76-

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 same circumstances in the
conduct of his own affairs.

          (b)  Except during the continuance of an Event of Default:

          (1)  The Trustee need perform only those duties that are specifically
     set forth in this Indenture and no others.

          (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 or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture but, in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture (but need not confirm or
     investigate the accuracy of mathematical calculations or other facts stated
     therein).

          (c)  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 does not limit the effect of paragraph (b) of this
     Section 7.01.

          (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 Sections 6.02, 6.05 or 6.06 hereof.

          (4)  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 rights, powers or duties if it shall have
     reasonable grounds 
<PAGE>
 
                                      -77-

     for believing that repayment of such funds or adequate indemnity
     satisfactory to it against such risk or liability is not reasonably assured
     to it.

          (d)  Whether or not therein expressly so provided, paragraphs (a),
(b), (c) and (e) of this Section 7.01 shall govern every provision of this
Indenture that in any way relates to the Trustee.

          (e)  The Trustee may refuse to perform any duty or exercise any right
or power unless it receives indemnity satisfactory to it in its sole discretion
against any loss, liability, expense or fee.

          (f)  The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Issuers or
any Guarantor. Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by the law.

Section 7.02.  Rights of Trustee.
               ----------------- 

          Subject to Section 7.01 hereof:

          (1)  The Trustee may rely on any document reasonably 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.

          (2)  Before the Trustee acts or refrains from acting, it may require
     an Officers' Certificate or an Opinion of Counsel, or both, which shall
     conform to the provisions of Section 12.05 hereof. The Trustee shall be
     protected and shall not be liable for any action it takes or omits to take
     in good faith in reliance on such certificate or opinion.

          (3)  The Trustee may act through its attorneys and agents and shall
     not be responsible for the misconduct or negligence of any agent appointed
     by it with due care.

          (4)  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.

          (5)  The Trustee may consult with counsel of its selection, and the
     advice or opinion of such counsel as to matters of law shall be full and
     complete authorization and
<PAGE>
 
                                     -78-

        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.

Section 7.03.  Individual Rights of Trustee.
               ---------------------------- 

           The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may make loans to, accept deposits from, perform
services for or otherwise deal with the either of the Issuers or any Guarantor,
or any Affiliates thereof, with the same rights it would have if it were not
Trustee. Any Agent may do the same with like rights. The Trustee, however, shall
be subject to Sections 7.10 and 7.11 hereof.

Section 7.04.  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 Notes or any Guarantee
or as to the value of, or perfection or priority of any security interest in,
any collateral pledged to the Trustee, it shall not be accountable for the
Issuers' or any Guarantor's use of the proceeds from the sale of Notes or any
money paid to the Issuers or any Guaranty pursuant to the terms of this
Indenture and it shall not be responsible for any statement in the Notes,
Guarantee or this Indenture other than its certificate of authentication.

Section 7.05.  Notice of Defaults.
               ------------------ 

           If a Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to each Noteholder notice of the Default within
90 days after it occurs. Except in the case of a Default in payment of the
principal of, or premium, if any, or interest on any Note the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in
good faith determine(s) that withholding the notice is in the interests of the
Noteholders.

Section 7.06.  Reports by Trustee to Holders.
               ----------------------------- 

           If required by TIA (S) 313(a), within 60 days after May 15 of any
year, commencing May 15, 1999, the Trustee shall mail to each Noteholder a brief
report dated as of such May 15 that complies with TIA (S) 313(a). The Trustee
also shall comply
<PAGE>
 
                                     -79-


with TIA (S) 313(b)(2). The Trustee shall also transmit by mail all reports as
required by TIA (S) 313(c) and TIA (S) 313(d).

           Reports pursuant to this Section 7.06 shall be transmitted by mail:

           (1) to all registered Holders of Notes, as the names and addresses of
such Holders appear on the Registrar's books; and

           (2) to such Holder of Notes as have, within the two years preceding
such transmission, filed their names and addresses with the Trustee for that
purpose.

           A copy of each report at the time of its mailing to Noteholders shall
be filed with the SEC and each stock exchange on which the Notes are listed. The
Issuers shall promptly notify the Trustee when the Notes are listed on any stock
exchange.

Section 7.07.  Compensation and Indemnity.
               -------------------------- 

           The Issuers and the Guarantors shall pay to the Trustee and Agents
from time to time such compensation as shall be agreed in writing between the
Issuers and the Trustee for its services hereunder (which compensation shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust). The Issuers and the Guarantors shall reimburse the Trustee
and Agents upon request for all reasonable disbursements, expenses and advances
incurred or made by it in connection with its duties under this Indenture,
including the reasonable compensation, disbursements and expenses of the
Trustee's agents and counsel.

           The Issuers and the Guarantors shall indemnify each of the Trustee
and any predecessor Trustee for, and hold each of them harmless against, any and
all loss, damage, claim, liability or expense, including without limitation
taxes (other than taxes based on the income of the Trustee or such Agent) and
reasonable attorneys' fees and expenses incurred by each of them in connection
with the acceptance or performance of its duties under this Indenture including
the reasonable costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder (including, without limitation, settlement costs). The Trustee
or Agent shall notify the Issuers and the Guarantors in writing promptly of any
claim asserted against the Trustee or
<PAGE>
 
                                     -80-


Agent for which it may seek indemnity. However, the failure by the Trustee or
Agent to so notify the Issuers and the Guarantors shall not relieve the Issuers
and Guarantors of their obligations hereunder except to the extent the Issuers
and the Guarantors are prejudiced thereby.

           Notwithstanding the foregoing, the Issuers and the Guarantors need
not reimburse the Trustee for any expense or indemnify it against any loss or
liability incurred by the Trustee through its negligence or bad faith. To secure
the payment obligations of the Issuers and the Guarantors in this Section 7.07,
the Trustee shall have a lien prior to the Notes on all money or property held
or collected by the Trustee except such money or property held in trust to pay
principal of and interest on particular Notes. The obligations of the Issuers
and the Guarantors under this Section 7.07 to compensate and indemnify the
Trustee, Agents and each predecessor Trustee and to pay or reimburse the
Trustee, Agents and each predecessor Trustee for expenses, disbursements and
advances shall be joint and several liabilities of the Issuers and each of the
Guarantors and shall survive the satisfaction, discharge and termination of this
Indenture, including any termination or rejection hereof under any bankruptcy
law.

           When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(6),(7) or (8) hereof occurs, the expenses
and the compensation for the services are intended to constitute expenses of
administration under any bankruptcy law.

           For purposes of this Section 7.07, the term "Trustee" shall include
any trustee appointed pursuant to Article 9.

Section 7.08.  Replacement of Trustee.
               ---------------------- 

           The Trustee may resign by so notifying the Issuers and the Guarantors
in writing. The Holders of a majority in principal amount of the outstanding
Notes may remove the Trustee by notifying the removed Trustee in writing and may
appoint a successor Trustee with the Issuers' written consent which consent
shall not be unreasonably withheld. The Issuers may remove the Trustee at their
election if :

           (1) the Trustee fails to comply with Section 7.10 hereof;
<PAGE>
 
                                     -81-

           (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;

           (4) the Trustee otherwise becomes incapable of acting; or

           (5) a successor corporation becomes successor Trustee pursuant to
Section 7.09 below.

           If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Issuers shall promptly appoint a successor
Trustee.

           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 a majority in principal amount of the outstanding Notes may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

           If the Trustee fails to comply with Section 7.10 hereof, any
Noteholder may petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor Trustee.

           A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Immediately following
such delivery, the retiring Trustee shall, subject to its rights under Section
7.07 hereof, transfer all property held by it as Trustee to the successor
Trustee, 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 Noteholder. Notwithstanding replacement of the
Trustee pursuant to this Section 7.08, the Issuers obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09.  Successor Trustee by Consolidation, Merger, Etc.
               -----------------------------------------------

           If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust assets to, another
corporation, subject to Section 7.10 
<PAGE>
 
                                     -82-

hereof, the successor corporation without any further act shall be the successor
Trustee.

Section 7.10.  Eligibility; Disqualification.
               ----------------------------- 

           This Indenture shall always have a Trustee who satisfies the
requirements of TIA (S) 310(a)(1) and (2) in every respect. The Trustee, or the
bank holding company of which the Trustee is a wholly-owned Subsidiary, shall
have a combined capital and surplus of at least $140,000,000 as set forth in its
most recent published annual report of condition. The Trustee shall comply with
TIA (S) 310(b), including the provision in (S) 310(b)(1).

Section 7.11.  Preferential Collection of Claims Against the Issuers.
               -----------------------------------------------------

           The Trustee shall comply with TIA (S) 311(a), excluding any creditor
relationship listed in TIA (S) 311(b).  A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated therein.

Section 7.12.  Paying Agents.
               ------------- 

           The Issuers shall cause each Paying Agent other than the Trustee to
execute and deliver to it and the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this Section 7.12:

           (A) that it will hold all sums held by it as agent for the payment of
     principal of, or premium, if any, or interest on, the Notes (whether such
     sums have been paid to it by the Issuers or by any obligor on the Notes) in
     trust for the benefit of Holders of the Notes or the Trustee;

           (B) that it will at any time during the continuance of any Event of
     Default, upon written request from the Trustee, deliver to the Trustee all
     sums so held in trust by it together with a full accounting thereof; and

           (C) that it will give the Trustee written notice within three (3)
     Business Days of any failure of the Issuers (or by any obligor on the
     Notes) in the payment of any installment of the principal of, premium, if
     any, or interest on, the Notes when the same shall be due and payable.

                 ARTICLE 8 AMENDMENTS, SUPPLEMENTS AND WAIVERS


Section 8.01.  Without Consent of Holders.
               -------------------------- 

           The Issuers and the Guarantors, when authorized by a Board Resolution
of each of them, and the Trustee may amend, waive or supplement this Indenture
or the Notes without notice to or consent of any Noteholder:

           (1) to provide for uncertificated Notes in addition to or in place of
certificated Notes;

           (2) to comply with any requirements of the SEC under the TIA;

           (3) to cure any ambiguity, defect or inconsistency, or to make any
other change that does not, in the opinion of the Trustee, materially and
adversely affect the rights of any noteholder; or

           (4) to add a Guarantor.

           The Trustee is hereby authorized to join with the Issuers and the
Guarantors in the execution of any supplemental indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate
agreements and stipulations which may be therein contained, but the Trustee
shall not be obligated to enter into any such supplemental indenture which
adversely affects its own rights, duties or immunities under this Indenture.

Section 8.02.  With Consent of Holders.
               ----------------------- 

     The Issuers (each when authorized by a Board Resolution), the Guarantors
(each when authorized by a Board Resolution) and the Trustee may modify or
supplement this Indenture, the Notes and the Pledge Agreement with the written
consent of the Holders of not less than a majority in aggregate principal amount
of the outstanding Notes.  The Holders of not less than a majority in aggregate
principal amount of the outstanding Notes may waive compliance in a particular
instance by the Issuers or Guarantors with any provision of this Indenture or
the Notes.  Subject to Section 8.04, without the consent of 
<PAGE>
 
                                     -84-

each Noteholder affected, however, an amendment, supplement or waiver, including

           (1) reduce the amount of Notes whose Holders must consent to an
     amendment, supplement or waiver to this Indenture;

           (2) reduce the rate of or change the time for payment of interest,
     including defaulted interest, on any Note;

           (3) reduce the principal of or premium on or change the stated

           (4) make any Note payable in money other than that stated in the Note
     or change the place of payment from New York, New York;

           (5) waive a Default on the payment of principal of, interest on, or

           (6) make any change in the provisions of this Indenture protecting
     the right of each holder of Notes 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, or permitting holders of a majority in principal
     amount of Notes to waive Defaults or Events of Default;

           (7) amend, change or modify in any material respect the obligation of
     the Issuers to make and consummate a Change of Control Offer in the event
     of a Change of Control or make and consummate an Asset Sale Offer with
     respect to any Asset Sale that has been consummated or modify any
     provisions or definitions with respect thereto;

           (8) modify or change any provision of this Indenture or the related
     definitions affecting the ranking of the Notes or any Guarantee in a manner
     which adversely affects the holders of Notes;

<PAGE>
 
                                     -85-

           (10) modify or waive a Default with respect to Section 6.01(8).

           After an amendment, supplement or waiver under this Section 8.02 or
Section 8.01 becomes effective, the Issuers shall mail to the Holders a notice
briefly describing the amendment, supplement or waiver.

           Upon the written request of the Issuers, accompanied by a Board
Resolution authorizing the execution of any such supplemental indenture, and
upon the receipt by the Trustee of evidence reasonably satisfactory to the
Trustee of the consent of the Noteholders as aforesaid and upon receipt by the
Trustee of the documents described in Section 8.06 hereof, the Trustee shall
join with the Issuers and the Guarantors in the execution of such supplemental
indenture unless such supplemental indenture adversely affects the Trustee's own
rights, duties or immunities under this Indenture, in which case the Trustee
may, but shall not be obligated to, enter into such supplemental indenture.

           It shall not be necessary for the consent of the Holders under this
Section 8.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

Section 8.03.  Compliance with Trust Indenture Act.
               ----------------------------------- 

           Every amendment to or supplement of this Indenture or the Notes shall
comply with the TIA as then in effect.

Section 8.04.  Revocation and Effect of Consents.
               --------------------------------- 

           Until an amendment, supplement, waiver or other action becomes
effective, a consent to it by a Holder of a Note is a continuing consent
conclusive and binding upon such Holder and every subsequent Holder of the same
Note or portion thereof, and of any Note issued upon the transfer thereof or in
exchange therefor or in place thereof, even if notation of the consent is not
made on any such Note. Any such Holder or subsequent Holder, however, may revoke
the consent as to his Note or portion of a Note, if the Trustee receives the
written notice of revocation before the date the amendment, supplement, waiver
or other action becomes effective.

           The Issuers may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled 
<PAGE>
 
                                     -86-


to consent to any amendment, supplement, or waiver. If a record date is fixed,
then, notwithstanding the preceding paragraph, those Persons who were Holders at
such record date (or their duly designated proxies), and only such Persons,
shall be entitled to consent to such amendment, supplement, or waiver or 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 unless the consent of the requisite
number of Holders has been obtained.

           After an amendment, supplement, waiver or other action becomes
effective, it shall bind every Noteholder, unless it makes a change described in
any of clauses (1) through (10) of Section 8.02 hereof. In that case the
amendment, supplement, waiver or other action shall bind each Holder of a Note
who has consented to it and every subsequent Holder of a Note or portion of a
Note that evidences the same debt as the consenting Holder's Note.

Section 8.05.  Notation on or Exchange of Notes.
               -------------------------------- 

           If an amendment, supplement, or waiver changes the terms of a Note,
the Trustee (in accordance with the specific written direction of the Issuers)
shall request the Holder of the Note (in accordance with the specific written
direction of the Issuers) to deliver it to the Trustee. In such case, the
Trustee shall place an appropriate notation on the Note about the changed terms
and return it to the Holder. Alternatively, if the Issuers or the Trustee so
determines, the Issuers in exchange for the Note shall issue, the Guarantors
shall endorse, and the Trustee shall authenticate a new Note that reflects the
changed terms. Failure to make the appropriate notation or issue a new Note
shall not affect the validity and effect of such amendment, supplement or
waiver.

Section 8.06.  Trustee to Sign Amendments, etc.
               ------------------------------- 

           The Trustee shall sign any amendment, supplement or waiver authorized
pursuant to this Article 8 if the amendment, supplement or waiver does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, but need not, sign it.  In signing or refusing to
sign such amendment, supplement or waiver the Trustee shall be entitled to
receive and, subject to Section 7.01 hereof, shall be fully protected in relying
upon an Officers' Certificate and an 
<PAGE>
 
                                     -87-


Opinion of Counsel stating that such amendment, supplement or waiver is
authorized or permitted by this Indenture and is a legal, valid and binding
obligation of the Issuers and Guarantors, enforceable against the Issuers and
Guarantors in accordance with its terms (subject to customary exceptions).

                                   ARTICLE 9

                      DISCHARGE OF INDENTURE; DEFEASANCE


Section 9.01.  Discharge of Indenture.
               ---------------------- 

           The Issuers and the Guarantors may terminate their obligations under
the Notes, the Guarantees and this Indenture, except the obligations referred to
in the last paragraph of this Section 9.01, if there shall have been canceled by
the Trustee or delivered to the Trustee for cancellation all Notes theretofore
authenticated and delivered (other than any Notes that are asserted to have been
destroyed, lost or stolen and that shall have been replaced as provided in
Section 2.07 hereof) and the Issuers have paid all sums payable by them
hereunder or deposited all required sums with the Trustee.

           After such delivery the Trustee upon Issuer request shall acknowledge
in writing the discharge of the Issuers' and the Guarantors' obligations under
the Notes, the Guarantees and this Indenture except for those surviving
obligations specified below.

           Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Issuers in Sections 7.07, 9.05 and 9.06 hereof shall survive.

Section 9.02.  Legal Defeasance.
               ---------------- 

           The Issuers may at their option, by Board Resolution of the Board of
Directors of each of the Issuers, defease and be discharged from their
obligations with respect to the Notes and the Guarantors discharged from their
obligations under the Guarantees on the date the conditions set forth in Section
9.04 below are satisfied (hereinafter, "Legal Defeasance").  For this purpose,
such Legal Defeasance means that the Issuers shall be deemed to have paid and
discharged the entire indebtedness represented by the Notes and to have
satisfied all its other obligations under such Notes and this Indenture insofar

     Subsidiaries is a party or by which they are bound;

           (5)  the Issuers shall have delivered to the Trustee an Opinion of

Request any money or U.S. Government Obligations held by it as provided in
Section 9.04 hereof which, in the opinion of a nationally-recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then

Trustee or Paying Agent.

shall, upon written demand of the Issuers, be paid to the Trustee, or if
sufficient moneys have been deposited pursuant to Section 9.01 hereof, to the
Issuers upon an Issuer Request (or, if such moneys had been deposited by the
Guarantors, to such Guarantors), and thereupon such Paying Agent shall be
released from all further liability with respect to such moneys.

Section 9.08.  Moneys Held by Trustee.

of, or premium, if any, or interest on any Note that are not applied but remain
unclaimed by the Holder of such Note for two years after the date upon which the
principal of, or premium, if any, or interest on such Note shall have
respectively become due and payable shall be repaid to the Issuers (or, if
appropriate, the Guarantors) upon an Issuer Request, or if such moneys are then
held by the Issuers or the Guarantors in trust, such moneys shall be released
from such trust; and the Holder of such Note entitled to receive such payment
shall thereafter, as an unsecured general creditor, look only to the Issuers and
the Guarantors for the payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money shall thereupon cease; provided,
                                                                     --------

after a date specified therein, which shall not be less than 30 days from the
date of such mailing or publication, any unclaimed balance of such moneys then
remaining will be repaid to the Issuers. After payment to the Issuers or the
Guarantors or the release of any money held in trust by the Issuers or any
Guarantors, as the case may be, Noteholders entitled to the money must look only
to the Issuers and the Guarantors for payment as general creditors unless
applicable abandoned property law designates another person.

                              GUARANTEE OF NOTES


Section 10.01.   Guarantee.
                 --------- 

          Subject to the provisions of this Article 10 each Guarantor hereby
jointly and severally conditionally guarantees, on a senior unsecured basis, to
each Holder of a Note authenticated and delivered by the Trustee and to the
Trustee and its successors, irrespective of the validity and enforceability of
this Indenture, the Notes or the obligations of the Issuers or any other
Guarantors to the Holders or the Trustee hereunder or thereunder, that the
principal of, interest and Additional Interest, if any, with respect to the
Notes will be duly and punctually paid in full when due, whether at maturity, by
acceleration or otherwise, and interest on the overdue principal and (to the
extent permitted by law) interest or Additional Interest, if any, with respect
to the Notes 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). The conditional Guarantee will become
effective only upon satisfaction of each of the following conditions: (i)
enforcement by the Trustee of the rights granted pursuant to the Pledge
Agreement with respect to the Senior Notes Collateral, (ii) Insight Ohio's
failure to redeem the Series A Preferred Interests after ten days as provided in
the Operating Agreement and (iii) an adjudication (other than a default judgment
based upon a failure to prosecute or defend any claim) is obtained relating to
such failure. The Guarantee of any Guarantor will be subordinate to any secured
Indebtedness of such Guarantor to the extent of the assets securing such
Indebtedness.
<PAGE>
 
                                     -94-

          This Guarantee shall remain in full force and effect and continue to
be effective should any petition be filed by or against the Issuers for
liquidation or reorganization, should the Issuers become insolvent or make an
assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Issuer's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Notes are
pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes, whether as a "voidable
preference," "fraudulent transfer," "fraudulent conveyance" or otherwise, all as
though such payment or performance had not been made. In the event that any
payment, or any part thereof, is rescinded, reduced, restored or returned, the
Notes shall, to the fullest extent permitted by law, be reinstated and deemed
reduced only by such amount paid and not so rescinded, reduced, restored or
returned.

          No stockholder, member, partner, agent, officer, director, employee or
incorporator, past, present or future, of any Guarantor, as such, shall have any
personal liability under this Guarantee by reason of his, her or its status as
such stockholder, member, partner, agent, officer, director, employee or
incorporator.

          The Guarantors shall have the right to seek contribution from any non-
paying Guarantor so long as the exercise of such right does not impair the
rights of the Holders under this Guarantee.

Section 10.02.   Execution and Delivery of Guarantees.
                 ------------------------------------ 

          To further evidence the Guarantee set forth in Section 10.01 hereof,
each Guarantor hereby agrees that a notation of such Guarantee, substantially in
the form included in Exhibit G hereto, shall be endorsed on each Note
                     ---------
authenticated and delivered by the Trustee and such Guarantee shall be executed
by either manual or facsimile signature of an Officer or an Officer of a general
partner, as the case may be, of each Guarantor. The validity and enforceability
of any Guarantee shall not be affected by the fact that it is not affixed to any
particular Note.

          Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 10.01 hereof shall remain in full 
<PAGE>
 
                                     -95-

force and effect notwithstanding any failure to endorse on each Note 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
Note on which such Guarantee is endorsed or at any time thereafter, such
Guarantor's Guarantee of such Note shall be valid nevertheless.

          The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of the Guarantor.

Section 10.03.   Limitation of Guarantee.
                 ----------------------- 

          The obligations of each Guarantor are limited to the maximum amount as
will, after giving effect to all other contingent and fixed liabilities of such
Guarantor 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, result in the obligations of such Guarantor under the Guarantee
not constituting a fraudulent conveyance or fraudulent transfer under federal or
state law.  Each Guarantor that makes a payment or distribution under a
Guarantee shall be entitled to a contribution from each other Guarantor in a pro
                                                                             ---
rata amount based on the Adjusted Net Assets of each Guarantor.

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

          The Issuers covenant and agree that they shall cause any Person which
becomes a Restricted Subsidiary to execute a supplemental indenture and any
other documentation requested by the Trustee satisfactory in form and substance
to the Trustee pursuant to which such Restricted Subsidiary shall guarantee the
obligations of the Issuers under the Notes and this Indenture in accordance with
this Article 10 with the same effect and to the same extent as if such Person
had been named herein as a Guarantor.

Section 10.05.   Release of Guarantor.
                 -------------------- 

          A Guarantor shall be released from all of its obligations under its
Guarantee if:
<PAGE>
 
                                     -96-

          (i)    the Guarantor has sold all or substantially all of its assets
     or the Issuers and their Restricted Subsidiaries have sold all of the
     Capital Stock of the Guarantor owned by them, in each case in a transaction
     in compliance with Sections 4.10 and 5.01 hereof; or

          (ii)   the Guarantor merges with or into or consolidates with, or
     transfers all or substantially all of its assets to, the Issuers or another
     Guarantor in a transaction in compliance with Section 5.01 hereof;

and in each such case, such Guarantor has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with.

Section 10.06.   Waiver of Subrogation.
                 --------------------- 

          Each Guarantor hereby irrevocably waives, until the prior payment in
full of all amounts outstanding hereunder and under the Notes, any claim or
other rights which it may now or hereafter acquire against any Issuer that arise
from the existence, payment, performance or enforcement of such Guarantor's
obligations under this Guarantee and this Indenture, including, without
limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any
Holder of Notes against any 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 any Issuer, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment on account of such claim or other rights. If any amount shall be paid to
any Guarantor in violation of the preceding sentence and the Notes 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
Holders of the Notes, and shall forthwith be paid to the Trustee for the benefit
of such Holders to be credited and applied upon the Notes, 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 10.06 is knowingly made in contemplation of such benefits.

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

          The release of any Senior Notes Collateral from the Pledge Agreement
or the release of, in whole or in part, the Liens created by the Pledge
Agreement, will not be deemed to impair the Lien of the Pledge Agreement in
contravention of the provisions hereof if and to the extent the Senior Notes
Collateral or Liens are released pursuant to the Pledge Agreement and pursuant
to the terms hereof. Any certificate or opinion required by TIA (S) 314(d) may
be made by an officer of the Issuers, except in cases which TIA (S) 314(d)
requires that such certificate or opinion be made by an independent person.

have power to institute and to maintain such suits and proceedings as it may
reasonably deem expedient to prevent any impairment of the Senior Notes

Pledge Agreement or this Indenture, and such suits and proceedings as the
Trustee may reasonably deem expedient to preserve or protect its interests and
the interests of the Holders in the Senior Notes Collateral 
<PAGE>
 
                                     -100-


(including power to institute and maintain suits or proceedings to restrain the
enforcement of or compliance with any legislative or other governmental
enactment, rule or order that may be unconstitutional or otherwise invalid if
the enforcement of, or compliance with, such enactment, rule or order would
impair the Senior Notes Collateral or be prejudicial to the interests of the
Holders or the Trustee).

Section 11.06.   Purchase Protected.
                 ------------------ 

          In no event shall any purchaser in good faith of any property
purported to be released hereunder be bound to ascertain the authority of the
Trustee to execute the release or to inquire as to the satisfaction of any
conditions required by the provisions hereof for the exercise of such authority
or to see to the application of any consideration given by such purchaser or
other transferee; nor shall any purchaser or other transferee of any property or
rights permitted by this Article 11 to be sold be under obligation to ascertain
or inquire into the authority of the Issuers to make any such sale or other
transfer.

Section 11.07.   Powers Exercisable by Receiver or Trustee.
                 -----------------------------------------

receiver or trustee, lawfully appointed, the powers conferred in this Article 11
upon the Issuers with respect to the release, sale or other disposition of such
property may be exercised by such receiver or trustee, and an instrument signed
by such receiver or trustee shall be deemed the equivalent of any similar
instrument of the Issuers or of any officer or officers thereof required by the
provisions of this Article 11.

Section 11.08.   Determinations Relating to Senior Notes Collateral.
                 --------------------------------------------------

          In the event (i) the Trustee shall receive any written request from
the Issuers under the Pledge Agreement for consent or approval with respect to
any matter or thing relating to any Senior Notes Collateral or the Issuers'
obligations with respect thereto (including, without limitation, the
determination as to whether any portion of the Senior Notes Collateral
constitutes released Senior Notes Collateral) or (ii) there shall be due to or
from the Trustee under the provisions of the Pledge Agreement any performance or
the delivery of any instrument or (iii) the Trustee shall become aware of any
nonperformance by the Issuers of any covenant or any breach of any
representation or warranty 
<PAGE>
 
                                     -101-

of the Issuers set forth in the Pledge Agreement, then, in each such event, the
Trustee shall be entitled to hire experts, consultants, agents and attorneys to
advise the Trustee on the manner in which the Trustee should respond to such
request or render any requested performance or response to such nonperformance
or breach. The Trustee shall be fully protected in the taking of any action
recommended or approved by any such expert, consultant, agent or attorney or
agreed to by a majority of Holders pursuant to Section 6.05.

Section 11.09.   Release upon Termination of the Issuers' Obligations.
                 ----------------------------------------------------

complied with, the Trustee shall (i) execute and deliver such releases,
termination statements and other instruments as the Issuers may reasonably
request evidencing the termination of the Liens created by the Pledge Agreement
and (ii) not be deemed to hold the Liens for the benefit of the Holders.

premium, if any, and overdue interest, to the extent lawful, at the rate equal
to 2% per annum in excess of the rate borne by the Notes.

2.   METHOD OF PAYMENT.

          The Issuers will pay interest on this Note provided for in Paragraph 1
above (except Defaulted interest) to the person who is the registered Holder of
this Note at the close of business on the February 1 or August 1 preceding the
Interest Payment Date (whether or not such day is a Business Day).  The Holder
must surrender this Note to a Paying Agent to collect principal payments.  The
Issuers will pay principal, premium, if any, and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts; provided, however, that the Issuers may pay principal, premium,
               --------  -------                                              
if any, and interest by check payable in such money. They may mail an interest

<PAGE>
 
                                      -5-

          Initially, Bank of Montreal Trust Company (the "Trustee") will act as
Paying Agent and Registrar.  The Issuers may change any Paying Agent or
Registrar without notice to the Holders of the Notes.  Neither the Issuers nor
any of their Subsidiaries or Affiliates may act as Paying Agent but may act as
Registrar.

4.   INDENTURE; RESTRICTIVE COVENANTS.

          The Issuers issued this Note under an Indenture dated as of August 21,
1998 (the "Indenture") among the Issuers, the Guarantor and the Trustee. The
terms of this Note include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code
(S)(S) 77aaa-77bbbb) as in effect on the date of the Indenture. This Note is
subject to all such terms, and the Holder of this Note is referred to the
Indenture and said Trust Indenture Act for a statement of them. All capitalized
terms in this Note, unless otherwise defined, have the meanings assigned to them
by the Indenture.

          The Notes are nonrecourse secured obligations of the Issuers limited
to $140,000,000 aggregate principal amount. The Indenture imposes certain
restrictions on, among other things, the incurrence of indebtedness, the
incurrence of liens and the issuance of capital stock by Subsidiaries of the
Issuers, mergers and sale of assets, the payments of dividends on, or the
repurchase of, capital stock of the Issuers and their Restricted Subsidiaries,
certain other restricted payments by the Issuers and their Restricted
Subsidiaries, certain transactions with, and investments in, their affiliates,
certain sale and lease-back transactions and a provision regarding change-of-
control transactions.

5.   OPTIONAL REDEMPTION.

          The Issuers, at their option, may redeem the Notes, in whole at any
time or in part from time to time on or after August 15, 2002 at the following
redemption prices (expressed as percentages of the principal amount thereof),
together, in each case, with accrued and unpaid interest, if any, to the
redemption date, if redeemed during the twelve-month period beginning on August
15 of each year listed below:

Year                               Redemption Price
- ----                               ----------------

2002. . . . . . . . . . . . .      105.500%
<PAGE>
 
                                      -6-

2003. . . . . . . . . . . . .      103.333%
2004. . . . . . . . . . . . .      101.667%
2005 and thereafter . . . . .      100.000%

          Notwithstanding the foregoing, the Issuers may redeem in the aggregate
up to 35% of the original principal amount of Notes at any time and from time to
time prior to August 15, 2001 at a redemption price equal to 110.0% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest, if
any, to the redemption date out of the Net Proceeds of one or more Equity
Offerings; provided that at least $91.0 million of the aggregate principal
           --------
amount of Notes remain outstanding immediately after the occurrence of any such
redemption and that any such redemption occurs within 90 days following the
closing of any such Equity Offering.

          In the event of a redemption of fewer than all of the Notes, the
Trustee shall select the Notes to be redeemed in compliance with the
requirements of the principal national securities exchange, if any, on which
such Notes are listed, or if such Notes are not then listed on a national
securities exchange, on a pro rata basis, by lot or in such other manner as the
                          --- ----
Trustee shall deem fair and equitable. The Notes will be redeemable in whole or
in part upon not less than 30 nor more than 60 days' prior written notice,
mailed by first class mail to a holder's last address as it shall appear on the
register maintained by the Registrar of the Notes. On and after any redemption
date, interest will cease to accrue on the Notes or portions thereof called for
redemption as long as funds are deposited with the Paying Agent.

6.   NOTICE OF REDEMPTION.

          Notice of redemption will be mailed via first class mail at least 30
days but not more than 60 days prior to the redemption date to each Holder of
Notes to be redeemed at its registered address as it shall appear on the
register of the Notes maintained by the Registrar. On and after any Redemption
Date, interest will cease to accrue on the Notes or portions thereof called for
redemption unless the Issuers shall fail to redeem any such Note.

7.   OFFERS TO PURCHASE.

          The Indenture requires that certain proceeds from Asset Sales be used,
subject to further limitations contained 
<PAGE>
 
                                      -7-

therein, to make an offer to purchase certain amounts of Notes in accordance
with the procedures set forth in the Indenture. The Issuers are also required to
make an offer to purchase Notes upon the occurrence of a Change of Control or an
Asset Swap in accordance with procedures set forth in the Indenture.

8.   REGISTRATION RIGHTS.

          Pursuant to the Registration Rights Agreement among the Issuers, the
Guarantor and CIBC Oppenheimer Corp., as initial purchaser of the Notes, the
Issuers will be obligated to consummate an exchange offer pursuant to which the
Holder of this Note shall have the right to exchange this Note for Notes of a
separate series issued under the Indenture (or a trust indenture substantially
identical to the Indenture in accordance with the terms of the Registration
Rights Agreement) which have been registered under the Securities Act, in like
principal amount and having substantially identical terms as the Notes.  The
Holders shall be entitled to receive certain additional interest payments in the
event such exchange offer is not consummated and upon certain other conditions,
all pursuant to and in accordance with the terms of the Registration Rights
Agreement.

9.   DENOMINATIONS, TRANSFER, EXCHANGE.

          The Notes are in registered form without coupons in denominations of
$1,000 and integral multiples thereof. A Holder may register the transfer or
exchange of Notes in accordance with the Indenture. The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Registrar need not register the transfer of or exchange any Note
selected for redemption or register the transfer of or exchange any Note for a
period of 15 days before the mailing of notice of redemption of Notes to be
redeemed or any Note after it is called for redemption in whole or in part,
except the unredeemed portion of any Note being redeemed in part.

10.  PERSONS DEEMED OWNERS.

          The registered Holder of this Note may be treated as the owner of it
for all purposes.

11.  UNCLAIMED MONEY.
<PAGE>
 
                                      -8-

          If money for the payment of principal, premium or interest on any Note
remains unclaimed for two years, the Trustee or Paying Agent will pay the money
back to the Issuers at their written request.  After that, Holders entitled to
money must look to the Issuers for payment as general creditors unless an
"abandoned property" law designates another person.

12.  AMENDMENT, SUPPLEMENT AND WAIVER.

          Subject to certain exceptions, the Indenture or the Notes may be
modified, amended or supplemented by the Issuers, the Guarantors and the Trustee
with the consent of the Holders of at least a majority in principal amount of
the Notes then outstanding and any existing Default or compliance with any
provision may be waived in a particular instance with the consent of the Holders
of a majority in principal amount of the Notes then outstanding. Without the
consent of Holders, the Issuers, the Guarantors and the Trustee may amend the
Indenture or the Notes or supplement the Indenture for certain specified
purposes including providing for uncertificated Notes in addition to
certificated Notes, and curing any ambiguity, defect or inconsistency, or making
any other change that does not, in the opinion of the Trustee, materially and
adversely affect the rights of any Holder.

13.  SUCCESSOR ENTITY.

          When a successor entity assumes all the obligations of its predecessor
under the Notes and the Indenture and immediately before and thereafter no
Default exists and certain other conditions are satisfied, the predecessor
entity will be released from those obligations.

14.  DEFAULTS AND REMEDIES.

          Events of Default are set forth in the Indenture. If an Event of
Default (other than an Event of Default pursuant to Sections 6.01(6) or (7) of
the Indenture with respect to either of the Issuers) occurs and is continuing,
the Trustee by notice to the Issuers, or the Holders of not less than 25% in
aggregate principal amount of the Notes then outstanding, may declare to be
immediately due and payable the entire principal amount of all the Notes then
outstanding plus accrued but unpaid interest to the date of acceleration;
provided, however, that after such acceleration but before judgment or decree
- --------  -------
based on such acceleration is obtained by the Trustee, the Holders of a 
<PAGE>
 
                                      -9-

majority in aggregate principal amount of the outstanding Notes may, under
certain circumstances, rescind and annul such acceleration and its consequences
if all existing Events of Default, other than the nonpayment of principal,
premium or interest that has become due solely because of the acceleration, have
been cured or waived and if the rescission would not conflict with any judgment
or decree. No such rescission shall affect any subsequent Default or impair any
right consequent thereto. In case an Event of Default specified in Sections
6.01(6) or (7) of the Indenture with respect to either of the Issuers occurs,
such principal amount, together with premium, if any, and interest with respect
to all of the Notes, shall be due and payable immediately without any
declaration or other act on the part of the Trustee or the Holders of the Notes.

15.  TRUSTEE DEALINGS WITH THE ISSUERS

          The Trustee under the Indenture, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the
Issuers, any Guarantor or their Affiliates, and may otherwise deal with the
Issuers any Guarantor or their Affiliates, as if it were not Trustee.

16.  NO RECOURSE AGAINST OTHERS.

          As more fully described in the Indenture, a director, officer,
employee, stockholder, member, partner, or agent, as such, of the Issuers or any
Guarantor shall not have any liability for any obligations of the Issuers or any
Guarantor under the Notes or the Indenture or for any claim based on, in respect
or by reason of, such obligations or their creation. The Holder of this Note by
accepting this Note waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of this Note.

17.  NO RECOURSE AGAINST THE ISSUERS.

          This Note will be a non-recourse obligation of the Issuers and the
only recourse a holder of this Note will have with respect to the payment of
principal or interest on this Note will be enforcement of the rights granted
pursuant to the Pledge Agreement with respect to the Senior Notes Collateral
(which will require mandatory redemptions of the Series A Preferred Interests)
and, failing that, enforcement of the Guarantee.

18.  DEFEASANCE AND COVENANT DEFEASANCE.
<PAGE>
 
                                     -10-

          The Indenture contains provisions for defeasance of the entire
indebtedness on this Note and for defeasance of certain covenants in the
Indenture upon compliance by the Issuers with certain conditions set forth in
the Indenture.

19.  ABBREVIATIONS.

          Customary abbreviations may be used in the name of a Holder of a Note

the entireties), JT TEN (joint tenants with right of survivorship and not as

Act).

20.  CUSIP NUMBERS.

          Pursuant to a recommendation promulgated by the Committee on Uniform
Note Identification Procedures, the Issuers have caused CUSIP Numbers to be
printed on the Notes and have directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Holders of the Notes. No

Dear Sirs:

          In connection with our proposed purchase of Notes, we confirm that:

          1.   We understand that any subsequent transfer of the Notes is
     subject to certain restrictions and conditions set forth in the Indenture
     dated as of August 21, 1998 relating to the Notes and we agree to be bound
     by, and not to resell, pledge or otherwise transfer the Notes except in
     compliance with, such restrictions and conditions and the Securities Act of
     1933, as amended (the "Securities Act").

          2.   We understand that the Notes have not been registered under the
     Securities Act, and that the Notes may not be offered, sold, pledged or
     otherwise transferred 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 Notes, we will do
     so only (i) to an Issuer or any subsidiary thereof, (ii) pursuant to an
     effective registration statement under the Securities Act, (iii) in
     accordance with Rule 144A under the Securities Act to a "qualified
     institutional buyer" (as defined in Rule 144A), (iv) to an institutional

     representations and agreements relating to the restrictions on transfer of
     the Notes, (v) outside the United States to persons other than U.S. persons
     in offshore transactions meeting the requirements of Rule 904 of Regulation

     to provide to any person purchasing any of the Notes from us a notice
     advising such purchaser that resales of the Notes are restricted as stated
     herein.

          3.   We understand that, on any proposed resale of any Notes, we will
     be required to furnish to you and the Issuers such certifications, legal
     opinions and other information as you and the Issuers may reasonably
     require to confirm that the proposed sale complies with the foregoing
     restrictions. We further understand that the Notes purchased by us will
     bear a legend to the foregoing effect.

          4.   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
     Notes, and we and any accounts for which we are acting each are able to
     bear the economic risk of our or their investment, as the case may be.

          5.   We are acquiring the Notes 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.

     You and the Issuers are entitled to rely upon this 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.

evidencing the Pledged Collateral, to the extent not previously delivered to the
Trustee, shall immediately upon receipt thereof by Pledgor be delivered to and
held by or on behalf of the Trustee pursuant hereto; provided, however, that to
                                                     --------  -------

delivered to the Trustee are in bearer form, the Trustee shall, on request of
the Pledgor, release and exchange such certificates for certificates in
registered form, issued in the name of the Pledgor and an appropriate amendment
to this Agreement shall be executed by the Pledgor. All such certificated
Pledged Collateral, if any, shall be in suitable form for transfer by delivery

Trustee shall have the right, at any time upon the occurrence of an Event of
Default which is continuing and without notice to Pledgor (except as required by

the Trustee or any of its nominees any or all of the Pledged Collateral. In
addition, the Trustee shall have the right at any time to exchange any
certificates representing or evidencing Pledged Collateral for certificates of
smaller or larger denominations.

the Trustee a pledge amendment, duly executed by Pledgor, in substantially the
form of Exhibit 1 hereto (each, a "Pledge Amendment"), in respect

Agreement, and confirming the attachment of the Lien hereby created on and in
respect of such additional shares. Pledgor hereby authorizes the Trustee to

represents, warrants and covenants as follows:

          (a) Perfection Actions; Prior Liens.  Upon the completion of the
              -------------------------------                             
     deliveries, filings and other actions contemplated hereby, the security
     interest granted to Trustee for the benefit of the Secured Parties pursuant
     to this Agreement in and to the Pledged Collateral will constitute a
     perfected security interest therein, superior and prior to the rights of
     all other Persons therein other than with respect to the Liens identified
     on Annex A relating to the items of Pledged Collateral identified on such
        -------                                                               
     annex (the "Prior Liens").

          (b) No Liens.  Pledgor is as of the date hereof, and, as to Pledged
              --------

     will be, the sole direct and beneficial owner of all Pledged Collateral
     pledged by it hereunder free from any Lien or other right, title or
     interest of any Person other than Prior Liens, and Pledgor shall defend the
     Pledged Collateral pledged by it hereunder against all claims and demands
     of all Persons at any time claiming any interest therein adverse to Trustee
     or any Secured Party.  There is no agreement, and  Pledgor shall not enter
     into any agreement or take any other action, that would result in the
     imposition of any other Lien, restrict the transferability of any of the
     Pledged Collateral or otherwise impair or conflict with Pledgors'
     obligations or the rights of Trustee hereunder, other than Prior Liens.

     reasonable request of Trustee, Pledgor agrees to use its reasonable best
     efforts to assist and aid Trustee to obtain as soon as practicable any
     necessary approvals for the exercise of any such remedies, rights and
     powers.

          (e) Due Authorization and Issuance.  All of the Pledged Shares have

     Communications Company, L.P. Pledgor shall not move its chief executive
     office except to such new location as Pledgor may establish in accordance

     until (i) it shall have given the Trustee not less than 45 days' prior
     written notice of its intention so to do, clearly describing such new
     location or name and providing such other information in connection
     therewith as the Trustee or any Secured Party may reasonably request, and
     (ii) with respect to such new location or name, Pledgor shall have taken
     all action satisfactory to the Trustee and the Secured Parties to maintain
     the perfection and priority of the security interest of the Trustee for the
     benefit of the Secured Parties in the Pledged Collateral intended to be
     granted hereby.

     Agreement will create a valid and perfected first priority security
     interest in the Pledged Collateral securing the payment of the Secured
     Obligations pursuant to: (i) the UCC in effect in each applicable
     jurisdiction, including, without limitation, the State of New York and (ii)
     the laws of any such other applicable jurisdiction.

          (h) Pledged Collateral.  All information set forth herein, including
              ------------------                                              
     the Schedules annexed hereto, and all information contained in any
     documents, schedules and lists heretofore delivered to any Secured Party in
     connection with this Agreement, in each case, relating to the Pledged
     Collateral is accurate and complete in all material respects.

          (i) No Violations, etc.  The pledge of the Pledged Collateral pursuant
              ------------------

     Reserve Board.

          (j) Operative Agreements. Pledgor has delivered to Trustee true,
              --------------------                                        
     correct and complete copies of the Operating Agreement. The Operating
     Agreement is in full force and effect, and there is no existing default by
     any party thereunder or any event which, with the giving of notice of
     passage of time or both, would constitute a default by any party
     thereunder. Pledgor shall deliver to Trustee a copy of any notice of
     default given or received by it under the Operating Agreement within ten
     (10) days after Pledgor gives or receives such notice. Pledgor will not
     terminate or agree to terminate the Operating Agreement or make any
     amendment or modification to the Operating Agreement which would have an
     adverse effect on the value of the Pledged Shares or the security intended
     to be provided by this Agreement.

          (k) No Options, Warrants, etc.  Except as provided in the Operating
              -------------------------                                      
     Agreement, there are no options, warrants, calls, rights, commitments or
     agreements of any character to which Pledgor is a party or by which it is
     bound obligating Pledgor to issue, deliver or sell or cause to be issued,
     delivered or sold, additional Pledged Shares or obligating Pledgor to
     grant, extend or enter 
<PAGE>
 
                                      -10-



     into any such option, warrant, call, right, commitment or agreement. Except
     as provided in the Operating Agreement, there are no voting trusts or other
     agreements or understandings to which Pledgor is a party with respect to
     the voting of the capital stock of any issuer of the Pledged Shares.

          Section 7.  Voting Rights; Distributions; etc.
                      --------------------------------- 

     (a)  (i)  Pledgor shall be entitled to exercise any and all voting and
     other consensual rights pertaining to the Pledged Shares or any part
     thereof for any purpose not inconsistent with the terms or purpose of this
     Agreement or the Indenture; provided, however, that Pledgor shall not in
                                 --------  -------

     the Lien on or have a material adverse effect on the value of the Pledged
     Collateral or the security intended to be provided by this Agreement.

          (ii) So long as no Event of Default shall have occurred which is
     continuing, Pledgor shall be entitled to receive and retain, and to utilize
     free and clear of the Lien of this Agreement, any and all Distributions,
     but only if and to the extent made in accordance with the provisions of the
     Indenture; provided, however, that any and all such Distributions
                --------  -------                                     
     consisting of rights or interests in the form of securities shall be, and
     shall be forthwith delivered to the Trustee to hold as Pledged Collateral
     and shall, if received by Pledgor, be received in trust for the benefit of
     the Trustee, be segregated from the other property or funds of Pledgor, and
     be forthwith delivered to the Trustee as Pledged Collateral in the same
     form as so received (with any necessary endorsement).

          (iii)  The Trustee shall be deemed without further action or formality
     to have granted to Pledgor all necessary consents relating to voting rights
     and shall, if necessary, upon written request of Pledgor and at Pledgor's
     sole cost and expense, from time to time execute and deliver (or cause to
     be executed and delivered) to Pledgor all such instruments as Pledgor may
     reasonably request in order to permit Pledgor to exercise 
<PAGE>

     the voting and other rights which it is entitled to exercise pursuant to
     Section 7(a)(i) hereof and to receive the Distributions which it is
     authorized to receive and retain pursuant to Section 7(a)(ii) hereof.

          (b) Upon the occurrence and during the continuance of an Event of
Default all rights of Pledgor to receive Distributions which it would otherwise
be authorized to receive and retain pursuant to Section 7(a)(ii) hereof shall
cease and all such rights shall thereupon become vested in the Trustee, which
shall during the continuance of such Event of Default have the sole right to
receive and hold as Pledged Collateral such Distributions.

          (c) Pledgor shall, at its sole cost and expense, from time to time
execute and deliver to the Trustee appropriate instruments as the Trustee may
reasonably request in order to permit the Trustee to receive all Distributions
which it may be entitled to receive under Section 7(b) hereof.

          (d) All Distributions which are received by Pledgor contrary to the
provisions of Section 7(b) hereof shall be received in trust for the benefit of
the Trustee, shall be segregated from other funds of Pledgor and shall
immediately be paid over to the Trustee as Pledged Collateral in the same form
as so received (with any necessary endorsement).

          (a) Pledgor shall not (i) sell, convey, assign or otherwise dispose
of, or grant any option, right or warrant with respect to, any of the Pledged
Collateral except as permitted by the Indenture or the Prior Liens, (ii) create
or permit to exist any Lien upon or with respect to any Pledged Collateral other
than the Lien and security interest granted to the Trustee pursuant to this
Agreement and Prior Liens or (iii) permit the issuer of the Pledged Shares to
merge, consolidate or change its legal form, unless (a) such transaction is
permitted by the Indenture and (b) all of the outstanding equity interests of

                                      -12-

          (b) Pledgor shall (i) cause each issuer of the Pledged Shares not to
issue any stock or other securities in addition to or in substitution for the
Pledged Shares issued by such issuer, except to Pledgor and (ii) pledge
hereunder, immediately upon its acquisition (directly or indirectly) thereof,
any and all additional shares of capital stock or other equity  securities of
the issuer of the Pledged Shares which are required to be pledged hereunder.

          Section 9.  Reasonable Care.  The Trustee shall be deemed to have
                      ---------------                                      
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if such Pledged Collateral is accorded treatment
substantially equivalent to that which the Trustee, in its individual capacity,
accords its own property consisting of similar instruments or interests, it
being understood that neither the Trustee nor any of the Secured Parties shall
have responsibility for (i) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relating to any
Pledged Collateral, whether or not the Trustee or any other Secured Party has or
is deemed to have knowledge of such matters, or (ii) taking any necessary steps
to preserve rights against any Person with respect to any Pledged Collateral.

          Section 10.  Remedies Upon Default; Decisions Relating to Exercise of
                       --------------------------------------------------------
Remedies.
- -------- 

          (a) If an Event of Default shall have occurred which is continuing,
the Trustee shall have the right, in addition to other rights and remedies
provided for herein or otherwise available to it to be exercised from time to
time, (i) to retain and apply the Distributions to the Secured Obligations as
provided in Section 11 hereof, (ii) to enforce the mandatory redemption
provisions of the Series A Preferred Interests pursuant to the Operating
Agreement and (iii) to exercise all the rights and remedies of a secured party
on default under the UCC in effect in the State of New York at that time or
under the laws of any other applicable jurisdiction, and the Trustee may also in
its sole discretion, without notice except as specified below, sell the Pledged
Collateral or any part thereof (including, without limitation, any partial
interest in the Pledged Shares) in one or more 
<PAGE>
 
                                      -13-

parcels at public or private sale, at any exchange, broker's board or at any of
the Trustee's offices or elsewhere, for cash, on credit or for future delivery,
and at such price or prices and upon such other terms as may be commercially
reasonable, irrespective of the impact of any such sales on the market price of
the Pledged Collateral. The Trustee or any other Secured Party or any of their
respective Affiliates may be the purchaser of any or all of the Pledged
Collateral at any such sale and shall be entitled, for the purpose of bidding
and making settlement or payment of the purchase price for all or any portion of
the Pledged Collateral sold at such sale, to use and apply any of the Secured
Obligations owed to such Person as a credit on account of the purchase price of
any Pledged Collateral payable by such Person at such sale. Each purchaser at
any such sale shall acquire the property sold absolutely free from any claim or
right on the part of Pledgor, and Pledgor hereby waives, to the fullest extent
permitted by law, all rights of redemption, stay and/or appraisal which it now
has or may at any time in the future have under any rule of law or statute now
existing or hereafter enacted. Pledgor acknowledges and agrees that, to the
extent notice of sale shall be required by law, ten days notice to Pledgor of
the time and place of any public sale or the time after which any private sale
or other intended disposition is to take place shall constitute reasonable
notification of such matters. No notification need be given to Pledgor if it has
signed, after the occurrence and during the continuance of an Event of Default,
a statement renouncing or modifying any right to notification of sale or other
intended disposition. The Trustee shall not be obligated to make any sale of
Pledged Collateral regardless of notice of sale having been given. The Trustee
may adjourn any public or private sale from time to time by announcement at the
time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned. Subject to the Trustee
acting at all times in good faith and in a commercially reasonable manner,
Pledgor hereby waives, to the fullest extent permitted by law, any claims
against the Trustee arising by reason of the fact that the price at which any
Pledged Collateral may have been sold at such a private sale was less than the
price which might have been obtained at a public sale, even if the Trustee
accepts the first offer received and does not offer such Pledged 
<PAGE>
 
                                      -14-

Collateral to more than one offeree. Subject to the Trustee at all times acting
in good faith and in a commercially reasonable manner, the Trustee shall not be
liable for any incorrect or improper payment made pursuant to this Section 10 in
the absence of gross negligence or willful misconduct.

          (b) Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act, and applicable state securities laws, the
Trustee may be compelled, with respect to any sale of all or any part of the
Pledged Collateral, to limit purchasers to Persons who will agree, among other
things, to acquire the Pledged Collateral for their own account, for investment
and not with a view to the distribution or resale thereof.  Pledgor acknowledges
that any such private sales may be at prices and on terms less favorable to the
Trustee than those obtainable through a public sale without such restrictions
(including, without limitation, a public offering made pursuant to a
registration statement under the Securities Act), and, notwithstanding such
circumstances, agrees that, subject to the Trustee at all times acting in good
faith and in a commercially reasonable manner, any such private sale shall be
deemed to have been made in a commercially reasonable manner and that the
Trustee shall have no obligation to engage in public sales and no obligation to
delay the sale of any Pledged Collateral for the period of time necessary to
permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would agree to do so.

          (c) Notwithstanding the foregoing, Pledgor shall, upon the occurrence
of an Event of Default, at the request of the Trustee, for the benefit of the
Trustee, cause any registration, qualification under or compliance with any
federal or state securities law or laws to be effected with respect to all or
any part of the Pledged Collateral as soon as practicable and at Pledgor's sole
cost and expense. Pledgor will use its reasonable efforts to cause such
registration to be effected (and be kept effective) and will use its reasonable
efforts to cause such qualification and compliance to be effected (and be kept
effective) as may be so requested and as would permit or facilitate the sale and
distribution of such Pledged Collateral, including, without
<PAGE>
 
                                      -15-

limitation, registration under the Securities Act (or any similar statute then
in effect), appropriate qualifications under applicable blue sky or other state
securities laws and appropriate compliance with any other government
requirements. Pledgor shall cause the Trustee to be kept advised in writing as
to the progress of each such registration, qualification or compliance and as to
the completion thereof, shall furnish to the Trustee such number of
prospectuses, offering circulars or other documents incident thereto as the
Trustee from time to time may request, and shall indemnify and shall cause the
issuer of the Pledged Collateral to indemnify the Trustee and all others
participating in the distribution of such Pledged Collateral against all claims,
losses, damages and liabilities caused by any untrue statement (or alleged
untrue statement) of a material fact contained therein (or in any related
registration statement, notification or the like) or by any omission (or alleged
omission) to state therein (or in any related registration statement,
notification or the like) a material fact required to be stated therein or
necessary to make the statements therein in light of the circumstances under
which made not misleading.

          (d) If the Trustee determines to exercise its right to sell any or all
of the Pledged Collateral, upon written request, Pledgor shall from time to time
furnish to the Trustee all such information as the Trustee may request in order
to determine the number of securities included in the Pledged Collateral which
may be sold by the Trustee as exempt transactions under the Securities Act and
the rules of the SEC thereunder, as the same are from time to time in effect.

          (e) Pledgor recognizes that, by reason of certain prohibitions
contained in laws, rules, regulations or orders of any foreign governmental
authority, the Trustee may be compelled, with respect to any sale of all or any
part of the Pledged Collateral, to limit purchasers to those who meet the
requirements of such foreign governmental authority.  Pledgor acknowledges that
any such sales may be at prices and on terms less favorable to the Trustee than
those obtainable through a public sale without such restrictions, and,
notwithstanding such circumstances, agrees that, subject to the Trustee at all
times acting in good faith, any such restricted sale shall be deemed to have
been made in a commercially reasonable manner
<PAGE>
 
                                      -16-

and that, except as may be required by applicable law, the Trustee shall have no
obligation to engage in public sales.

          (f) In addition to any of the other rights and remedies hereunder, the
Trustee shall have the right to institute a proceeding seeking specific
performance in connection with any of the agreements or obligations hereunder or
under the mandatory redemption provisions of the Series A Preferred Interests
pursuant to the Operating Agreement.

          (g) Notwithstanding any other provision of this Agreement, any
foreclosure on, sale, transfer or other disposition of, or the exercise of any
right to vote or consent with respect to, any of the Pledged Collateral as
provided herein or any other action taken or proposed to be taken by the Trustee
hereunder which would affect the operational, voting or other control of the
Pledgor or any of its subsidiaries shall be made in accordance with all
applicable laws, rules and regulations, including the terms of any governmental
franchise under which the Pledgor or such subsidiary operates.

          Section 11.  Application of Proceeds.  All Distributions held from
                       -----------------------                              
time to time by the Trustee and all proceeds received by the Trustee in respect
of any sale of, collection from, or other realization upon all or any part of
the Pledged Collateral pursuant to the exercise by the Trustee of its remedies
as a secured creditor as provided in Section 10 hereof shall be applied,
together with any other sums then held by the Trustee pursuant to this
Agreement, promptly by the Trustee as set forth in the Indenture.

          Section 12.  Expenses.  Pledgor will upon demand pay to the Trustee
                       --------                                              
the amount of any and all reasonable expenses, including the reasonable fees and
expenses of its counsel and the reasonable fees and expenses of any experts and
agents, which the Trustee may incur in connection with (i) the collection of the
Secured Obligations, (ii) the enforcement and administration of this Agreement,
(iii) the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Pledged Collateral, (iv) the exercise or
enforcement of any of the rights of the Trustee or any Secured Party hereunder
or (v) the failure by Pledgor to
<PAGE>
 
                                      -17-

perform or observe any of the provisions hereof. All amounts payable by Pledgor
under this Section 12 shall be due upon demand and shall be part of the Secured
Obligations. Pledgor's obligations under this Section 12 shall survive the
termination of this Agreement and the discharge of Pledgor's other obligations
hereunder.

          Section 13.  No Waiver; Cumulative Remedies.
                       ------------------------------ 

          (a) No failure on the part of the Trustee to exercise, no course of
dealing with respect to, and no delay on the part of the Trustee in exercising,
any right, power or remedy hereunder shall operate as a waiver thereof; nor
shall any single or partial exercise of any such right, power or remedy
hereunder preclude any other or further exercise thereof or the exercise of any
other right, power or remedy. The remedies herein provided are cumulative and
are not exclusive of any remedies provided by law.

          (b) In the event the Trustee shall have instituted any proceeding to
enforce any right, power or remedy  under this Agreement by foreclosure, sale,
entry or otherwise, and such proceeding shall have been discontinued or
abandoned for any reason or shall have been determined adversely to the Trustee,
then and in every such case, to the extent permitted by law, Pledgor, the
Trustee and each Secured Party shall be restored to their respective former
positions and rights hereunder with respect to the Pledged Collateral, and all
rights, remedies and powers of the Trustee and the Secured Parties shall
continue as if no such proceeding had been instituted.

          Section 14.  The Trustee.  The Trustee has been appointed as the
                       -----------                                        
trustee pursuant to the Indenture.  The actions of the Trustee hereunder are
subject to the provisions of the Indenture.  The Trustee shall have the right
hereunder to make demands, to give notices, to exercise or refrain from
exercising any rights, and to take or refrain from taking action (including,
without limitation, the release or substitution of Pledged Collateral), in
accordance with this Agreement and the Indenture.  The Trustee may resign and a
successor Trustee may be appointed in the manner provided in the Indenture.
Upon the acceptance of any appointment as the
<PAGE>
 
                                      -18-

Trustee by a successor Trustee, that successor Trustee shall thereupon succeed
to and become vested with all the rights, powers, privileges and duties of the
retiring Trustee under this Agreement, and the retiring Trustee shall thereupon
be discharged from its duties and obligations under this Agreement. After any
retiring Trustee's resignation, the provisions of this Agreement shall inure to
its benefit as to any actions taken or omitted to be taken by it under this
Agreement while it was the Trustee.

          Section 15.  The Trustee May Perform; the Trustee Appointed
                       ----------------------------------------------
AttorneyinFact.  The Pledgor shall from time to time, and at all times after an
- --------------                                                                 
Event of Default shall have occurred, execute all such further instruments and
documents and do all such things as the Trustee reasonably may deem desirable
for the purpose of obtaining the full benefit of this Agreement and of the
rights, title, interest, powers, authorities and discretions conferred on the
Trustee by this Agreement.  The Pledgor hereby irrevocably appoints the Trustee
its attorneyinfact for it and in its name and on its behalf and as its act and
deed to execute, seal and deliver and otherwise perfect any deed, assurance,
agreement, instrument or take any action which it may deem necessary or
advisable for any of the purposes of this Agreement; provided that the Trustee
                                                     --------                 
shall not exercise such power until an Event of Default shall have occurred and
is continuing.  The Trustee shall have full power to delegate this power of
attorney but no such delegation shall preclude the subsequent exercise of such
power by the Trustee itself or preclude the Trustee from subsequent delegation
to some other person and any delegation may be revoked by the Trustee at any
time.  The foregoing grant of authority is a power of attorney coupled with an
interest and such appointment shall be irrevocable for the term of this
Agreement.  The Pledgor hereby ratifies all that such attorney shall lawfully do
or cause to be done by virtue hereof.  Any and all amounts expended by the
Trustee pursuant to this Section 15 shall be paid by Pledgor promptly upon
demand therefor, with interest at the rate then in effect under the Indenture
during the period from and including the date on which funds were so expended to
the date of repayment. Pledgor's obligations under this Section 15 shall survive
the termination of this Agreement and the discharge of Pledgor's other
obligations under this Agreement and the Indenture.

          Section 16.  Indemnity.
                       --------- 

          (a) Indemnity.  Pledgor agrees to indemnify, pay and hold harmless the
              ---------                                                         
Trustee and each of the Secured Parties and the officers, directors, employees,
agents and Affiliates of the Trustee and each of the Secured Parties
(collectively, the "Indemnitees") from and against any and all other
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs (including, without limitation, settlement costs), expenses or
disbursements of any kind or nature whatsoever (including, without limitation,
the reasonable fees and disbursements of counsel for such Indemnitees in
connection with any investigative, administrative or judicial proceeding
commenced or threatened, whether or not such Indemnitee shall be designated a
party thereto), which may be imposed on, incurred by, or asserted against that
Indemnitee, in any manner relating to or arising out of this Agreement
(including, without limitation, any misrepresentation by Pledgor in this
Agreement) (the "indemnified liabilities"); provided that Pledgor shall not have
                                            --------                            
any obligation to an Indemnitee hereunder with respect to indemnified
liabilities if it has been determined by a final decision (after all appeals and
the expiration of time to appeal) of a court of competent jurisdiction that such
indemnified liability arose from the gross negligence or willful misconduct of
that Indemnitee.  To the extent that the undertaking to indemnify, pay and hold
harmless set forth in the preceding sentence may be unenforceable because it is
violative of any law or public policy, Pledgor shall contribute the maximum
portion which it is permitted to pay and satisfy under applicable law, to the
payment and satisfaction of all indemnified liabilities incurred by the
Indemnitees or any of them.

          (b) Survival.  The obligations of Pledgor contained in this Section 16
              --------                                                          
shall survive the termination of this Agreement and the discharge of Pledgor's
other obligations under this Agreement.

          (c) Reimbursement.  Any amounts paid by any Indemnitee as to which
              -------------                                                 
such Indemnitee has the right to reimbursement shall constitute Secured
Obligations secured by the Pledged Collateral.

          Section 17.  Modification in Writing.  No amendment, modification,
                       -----------------------                              
supplement, termination or waiver of or to any provision of this Agreement, nor
consent to any departure by Pledgor therefrom, shall be effective unless the
same shall be done in accordance with the terms of the Indenture and unless in
writing and signed by the Trustee.  Any amendment, modification or supplement of
or to any provision of this Agreement, any waiver of any provision of this
Agreement and any consent to any departure by Pledgor from the terms of any
provision of this Agreement shall be effective only in the specific instance and
for the specific purpose for which made or given.  Except where notice is
specifically required by this Agreement or the Indenture, no notice to or demand
on Pledgor in any case shall entitle Pledgor to any other or further notice or
demand in similar or other circumstances.

          Section 18.  Termination; Release.  When all the Secured Obligations
                       --------------------                                   
have been paid in full, this Agreement shall terminate.  Upon termination of
this Agreement or any release of Pledged Collateral in accordance with the
provisions of the Indenture, the Trustee shall, upon the request and at the sole
cost and expense of Pledgor, forthwith assign, transfer and deliver to Pledgor,
against receipt and without recourse to or warranty by the Trustee, such of the
Pledged Collateral to be released (in the case of a release) as may be in the
possession of the Trustee and as shall not have been sold or otherwise applied
pursuant to the terms hereof, and, with respect to any other Pledged Collateral,
proper instruments (including UCC termination statements on Form UCC3)
acknowledging the termination of this Agreement or the release of such Pledged
Collateral, as the case may be.

          Section 19.  Notices.  Unless otherwise provided herein or in the
                       -------                                             
Indenture, any notice or other communication herein required or permitted to be
given shall be given in the manner set forth in the Indenture, as to either
party, addressed to it at the address set forth in the Indenture or at such
other address as shall be designated by such party in a written notice to the
other party complying as to delivery with the terms of this Section 19; provided
                                                                        --------

Trustee.

          Section 20.  Continuing Security Interest; Assignment.  This Agreement
                       ----------------------------------------                 
shall create a continuing security interest in the Pledged Collateral and shall
(i) be binding upon Pledgor, its successors and assigns and (ii) inure, together
with the rights and remedies of the Trustee hereunder, to the benefit of the
Trustee and the other Secured Parties and each of their respective successors,
transferees and assigns; no other Persons (including, without limitation, any
other creditor of Pledgor) shall have any interest herein or any right or
benefit with respect hereto.  Without limiting the generality of the foregoing
clause (ii), any Secured Party may assign or otherwise transfer any indebtedness
held by it secured by this Agreement to any other Person, and such other Person
shall thereupon become vested with all the benefits in respect thereof granted
to such Secured Party, herein or otherwise, subject however, to the provisions
of the Indenture.

          Section 21.  GOVERNING LAW; TERMS.  THIS AGREEMENT SHALL BE GOVERNED
                       --------------------                                   
BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS, EXCEPT TO
THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER,
OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR PROPERTY ARE GOVERNED BY THE
LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK.

          Section 22.  Agent for Service; Submission to Jurisdiction; Waiver of
                       --------------------------------------------------------
Immunities.  By the execution and delivery of this Agreement, the Pledgor
- ----------                                                               
submits to the non-exclusive jurisdiction of any federal or state court in The
City of New York, Borough of Manhattan, State of New York in any suit or
proceeding arising out of or relating to this Agreement or the Pledged
Collateral or that may be instituted or brought under federal or state
securities laws.

          To the extent that the Pledgor has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether
through service of notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property, it
hereby irrevocably waives such immunity in respect of its obligations under this
Agreement.  In addition, 
<PAGE>
 
                                      -22-

the Pledgor irrevocably waives and agrees not to assert, by way of motion, as a
defense, or otherwise in any such suit, action or proceeding, any claim that it
is not personally subject to the jurisdiction of the abovementioned courts for
any reason whatsoever, that such suit, action or proceeding is brought in an
inconvenient forum or that the venue for such suit is improper, or that this
Agreement or the subject matter hereof may not be enforced in such courts.

          The Pledgor and the Trustee agree that a final judgment in any such
suit, action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Section 22 shall affect the right of the Trustee to serve legal
process in any other manner permitted by law or affect the right of the Trustee
to bring any action or proceeding against any Pledgor or its property in the
courts of any other jurisdictions.

          Section 23.  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 24.  Execution in Counterparts.  This Agreement and any
                       -------------------------                         
amendments, waivers, consents or supplements hereto may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original,
but all such counterparts together shall constitute one and the same Agreement.

          Section 25.  Headings.  The Section headings used in this Agreement
                       --------                                              
are for convenience of reference only and shall not affect the construction of
this Agreement.

          Section 26.  Obligations Absolute.  All obligations of Pledgor
                       --------------------

     readjustment, composition, liquidation or the like of Pledgor;

             (ii) any lack of validity or enforceability of the Indenture or any

             (iii)  any change in the time, manner or place of pay ment of, or
     in any other term of, all or any of the Secured Obligations, or any other
     amendment or waiver of or any consent to any departure from the Indenture
     or any other agreement or instrument relating thereto;

             (iv) any exchange, release or nonperfection of any other
     collateral, or any release or amendment or waiver of or consent to any
     departure from any guarantee, for all or any of the Secured Obligations;

             (v) any exercise or nonexercise, or any waiver of any right,
     remedy, power or privilege under or in respect of this Agreement, the

     specifically set forth in a waiver granted pursuant to the provisions of
     Section 17 hereof; or

             (vi) any other circumstances which might otherwise constitute a

Ladies and Gentlemen:

     We have been requested by Coaxial Communications of Central Ohio, Inc., an
Ohio corporation, Phoenix Associates, a Florida general partnership
(collectively, the "Issuers"), and Insight Communications of Central Ohio, LLC,
a Delaware limited liability company (the "Guarantor"), to furnish our opinion
in connection with the registration statement (the "Registration Statement") on
Form S-4, filed concurrently herewith, with respect to the registration of
$140,000,000 aggregate principal amount of 10% Senior Notes due 2006 of the
Issuers (the "Exchange Notes") to be offered in exchange for outstanding 10%
Senior Notes due 2006 (the "Original Notes"), which Exchange Notes will be
guaranteed (the Guarantees") by the Guarantor. The Exchange Notes and the
Guarantees will be issued under an indenture relating to the Original Notes and
the Exchange Notes (the "Indenture") among the Issuers, the Guarantor and Bank
of Montreal Trust Company, as Trustee.

     We have made such examination as we have deemed necessary for the purpose
of this opinion. Based upon such examination, it is our opinion that when the
Registration Statement has become effective under the Securities Act of 1933, as
amended, the Exchange Notes have been duly executed and authenticated in
accordance with the Indenture, the Indenture has been qualified under the Trust
Indenture Act of 1939, as amended, the Original Notes have been validly tendered
to the Company and the Exchange Notes have been delivered in exchange therefor,
the Exchange Notes and the Guarantees will be validly issued and binding
obligations 
<PAGE>
 
of the Issuers and the Guarantor, subject in each case to the effect of (i)
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting the rights of creditors generally and (ii) the
application of general principles of equity (regardless of whether enforcement
is considered in proceedings at law or in equity).

     We express no opinion as to the applicability (and, if applicable, the
effect) of Section 548 of the United States Bankruptcy Code or any comparable
provision of state law to the conclusions expressed above.

     We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York, the Federal laws of the
United States of America, and the Limited Liability Company Act of the State of
Delaware.

     The opinion is rendered solely to you in connection with the above matter.
This opinion may not be relied upon by you for any other purposes or relied upon
or furnished to any other person without our prior written consent.

     We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the reference to our name under the caption "Legal
Matters" in the prospectus included in the Registration Statement.


                                      Very truly yours,

Ladies and Gentlemen:

     We have been requested by Coaxial Communications of Central Ohio, Inc.
("Coaxial"), an Ohio corporation, Phoenix Associates (collectively with Coaxial,
the "Issuers"), a Florida general partnership, and Insight Communications of
Central Ohio, LLC, a Delaware limited liability company, to furnish our opinion
in connection with the registration statement (the "Registration Statement") on
Form S-4, filed concurrently herewith, with respect to the registration of
$140,000,000 aggregate principal amount of 10% Senior Notes due 2006 of the
Issuers (the "Exchange Notes") to be offered (the "Exchange Offer") in exchange
for outstanding 10% Senior Notes due 2006 (the "Original Notes").

     We have made such examination as we have deemed necessary for the purpose
of this opinion. Based upon the terms of the Exchange Offer, the Original Notes
and the Exchange Notes, which are set forth in the Registration Statement, we
are of the opinion that the exchange of the Original Notes for Exchange Notes
pursuant to the Exchange Offer will not be treated as an "exchange" for federal
income tax purposes because the Exchange Notes will not (in our opinion) be
considered to differ materially in kind or extent from the Original Notes.
Rather, it is our opinion that the Exchange Notes received by a holder will be
treated as a continuation of the Original Notes in the hands of such holder and
that, consequently, there will be no federal income tax consequences to holders
exchanging Original Notes for Exchange Notes pursuant to the Exchange Offer.

     The foregoing opinion is based upon current provisions of the Internal
Revenue Code of 1986, as amended, the Treasury Regulations promulgated
thereunder, published pronouncements of the Internal Revenue Service, and case
law, any of which may be changed at any time with retroactive effect.  We
undertake no obligation to update this opinion in respect of any such changes.

absence of any such management agreement, any rights of the shareholders of
Central under this Agreement may be exercised on behalf of any of the Existing

          SECTION 4.  INDEMNIFICATION

     4.1  Indemnification.

     Central shall indemnify, defend, and hold harmless each shareholder and its
members, officers, and directors (all indemnified Persons being referred to as
"Indemnified Persons" for purposes of this Section 4) 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 (including any action threatened or instituted by or in the right
of Central), by reason of the fact that such shareholder is or was exercising
any of the powers of a director, officer, employee, or agent of Central by
virtue of the rights granted to such shareholder under this Agreement against
expenses (including attorneys' fees, filing fees, court reporters' fees, and
transcript costs), judgments, fines, and amounts paid in settlement actually and
reasonably incurred by such Indemnified Person in connection with such action,
suit, or proceeding if the act or omission of the Indemnified Person giving rise
to any claim for indemnification under this Section 4.1 was not occasioned by an
intent to cause injury to Central or by a reckless disregard for the best
interests or Central, and in respect of any criminal action or proceeding, such
Indemnified Person had no reasonable cause to believe his or its conduct was
unlawful. It shall be presumed that no act or omission of an Indemnified Person
was occasioned by an intent to cause injury to Central or by a reckless
disregard for the best interests of Central and, in respect to any criminal
matter, that such Indemnified Person had no reasonable cause to believe his or
its conduct was unlawful; the presumption recited in this Section 4.1 can be
rebutted only by clear and convincing evidence, and the termination of any
action, suit, or proceeding by judgment, order, settlement, or conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, rebut
such presumption.

     4.2  Court-Approved Indemnification.

     Anything contained in this Agreement or elsewhere to the contrary
notwithstanding:

          (a)  Central shall not indemnify any Indemnified Person who was a
party to any completed action or suit instituted by or in the right of Central
to procure a judgment in its favor in respect of any claim, issue, or matter
asserted in such action or suit as to which such Indemnified Person shall have
been adjudged to be liable for an act or omission occasioned by a deliberate
intent to cause injury to Central or by a reckless disregard for the best
interests of Central, unless and only to the extent that the Court of Common
Pleas of Franklin County, Ohio or the court in which such action or suit was
brought shall determine upon application that, despite such adjudication of
liability, and in view of all the circumstances of the case, such Indemnified
Person is fairly and reasonably entitled to such indemnity as such Court of
Common Pleas or such other court shall deem proper; and
<PAGE>
 
          (b)  Central shall promptly make any such unpaid indemnification as is
determined by a court to be proper as contemplated by this Section 4.2.

     4.3  Determination Required.

     Any indemnification required under Section 4.1 and not precluded under
Section 4.2 shall be made by Central only upon a determination that such
indemnification is proper in the circumstances because the Indemnified Person
has met the applicable standard of conduct set forth in Section 4.1. Such
determination may be made only (a) by a majority vote of a quorum consisting of
directors of Central who were not and are not parties to, or threatened with,
any such action, suit, or proceeding, or (b) if such a quorum is not obtainable
or if a majority of a quorum of disinterested directors so directs, in a written
opinion by independent legal counsel other than an attorney, or a firm having
associated with it an attorney, who has been retained by or who has performed
services for Central, or any Person to be indemnified, within the past five
years, or (c) by the shareholders, or (d) by the Court of Common Pleas of
Franklin County, Ohio or (if Central is a party thereto) the court in which such
action, suit, or proceeding was brought, if any; any such determination may be
made by a court under clause (d) of this Section 4.3 at any time, including any
time before, during, or after the time when any such determination may be
requested of, be under consideration by, or have been denied or disregarded by
the disinterested directors under clause (a) or by independent legal counsel
under clause (b) or by the shareholders under clause (c) of this Section 4.3;
and no failure for any reason to make any such determination, and no decision
for any reason to deny any such determination, by the disinterested directors
under clause (a) or by independent legal counsel under clause (b) or by the
shareholders under clause (c) of this Section 4.3 shall be evidence in rebuttal
of the presumption recited in Section 4.1. Any determination made by the
disinterested directors under clause (a) or by independent legal counsel under
clause (b) of this Section 4.3 to make indemnification in respect of any claim,
issue, or matter asserted in an action or suit threatened or brought by or in
the right of Central shall be promptly communicated to the Person who threatened
or brought such action or suit, and within ten days after receipt of such
notification such Person shall have the right to petition the Court of Common
Pleas of Franklin County, Ohio or the court in which such action or suit was
brought, if any, to review the reasonableness of such determination.

     4.4  Indemnification for Expenses.

          (a) Anything contained in this Agreement or elsewhere to the contrary
notwithstanding, to the extent that an Indemnified Person has been successful on
the merits or otherwise in defense of any action, suit, or proceeding referred
to in Section 4.1, or in defense of any claim, issue, or matter therein, such
Indemnified Person shall be promptly indemnified by Central against expenses
(including attorneys' fees, filing fees, court reporters' fees, and transcript
costs) actually and reasonably incurred by such Indemnified Person in connection
therewith.

          (b) The provisions of Section 1701.13(E)(5)(a) of the Corporation Law
do not apply to Central. Expenses (including attorneys' fees, filing fees, court
reporters' fees, and transcript costs) incurred in defending any action, suit,
or proceeding referred to in Section 4.1
<PAGE>
 
shall be paid by Central in advance of the final disposition of such action,
suit, or proceeding to or on behalf of the Indemnified Person promptly as such
expenses are incurred by the Indemnified Person, but only if such Indemnified
Person shall first agree, in writing, to repay all amounts so paid in respect to
any claim, issue, or other matter asserted in such action, suit, or proceeding
in defense of which such Indemnified Person shall not have been successful on
the merits or otherwise if it is proved by clear and convincing evidence in a
court of competent jurisdiction that, in respect to any such claim, issue, or
other matter, the Indemnified Person's relevant action or failure to act was
occasioned by a deliberate intent to cause injury to Central or a reckless
disregard for the best interests of Central, unless, and only to the extent
that, the Court of Common Pleas of Franklin County, Ohio or the court in which
such action or suit was brought shall determine upon application that, despite
such determination, and in view of all of the circumstances, such Indemnified
Person is fairly and reasonably entitled to all or part of such indemnification.

          (c) For the purposes of this Section 4, and as an example and not by
way of limitation, an Indemnified Person shall be deemed to have been successful
on the merits or otherwise in defense of any action, suit, or proceeding
referred to in Section 4.1, or in defense of any claim, issue, or other matter
therein, if such action, suit, or proceeding shall be terminated as to such
Indemnified Person, with or without prejudice, without the entry of a judgement
or order against such Indemnified Person, without a conviction of such
Indemnified Person, without the imposition of a fine upon such Indemnified
Person, and without such Indemnified Person's payment or agreement to pay any
amount in settlement thereof (whether or not any such termination is based upon
a judicial or other determination of the lack of merit of the claims made
against such Indemnified Person or otherwise results in a vindication of such
Indemnified Person).

     4.5  Section 4 Not Exclusive.

     The indemnification provided by this Section 4 shall not be exclusive of,
and shall be in addition to, any other rights to which any Indemnified Person
may be entitled under the Articles of Incorporation or Code of Regulations of
Central, any agreement, a vote of disinterested directors, or otherwise.

     4.6  Insurance.

     Central may purchase and maintain insurance, or furnish similar protection,
including trust funds or letters of credit, for or on behalf of any Indemnified
Person against any liability asserted against such Indemnified Person and
incurred by such Indemnified Person, whether or not Central would have the
obligation or the power to indemnify such Indemnified Person against such
liability under the provisions of this Section 4. Insurance may be purchased
from or maintained with a Person in which Central has a financial interest.

     4.7  Venue.

     Any action, suit, or proceeding to determine a claim for, or for repayment
to Central of, indemnification under this Section 4 may be maintained by the
Indemnified Person claiming
<PAGE>
 
such
indemnification, or by Central, in the Court of Common Pleas of Franklin County,
Ohio. Central and (by claiming or accepting such indemnification) each
Indemnified Person consents to the exercise of jurisdiction over its or his
person by the Court of Common Pleas of Franklin County, Ohio in any such action,
suit, or proceeding.

     4.8  Exculpation.

     No Indemnified Person shall be liable, in damages or otherwise, to Central
for any loss that arises out of the exercise by any shareholder of Central of
any of the powers of a director, officer, employee, or agent of Central by
virtue of the rights granted to such shareholder under this Agreement, unless
such Indemnified Person's act or omission was occasioned by an intent to cause
injury to Central or by a reckless disregard for the best interests or Central.

     4.9  Persons Entitled to Indemnity.

     Any Person who is within the definition of "Indemnified Person" at the time
of any action or inaction relating to the exercise by any shareholder of Central
of its rights under this Agreement shall be entitled to the benefits of this
Section 4 as an "Indemnified Person" with respect thereto, regardless of whether
such Person continues to be within the definition of "Indemnified Person" at the
time of his or its claim for indemnification or exculpation hereunder. The
benefits of this Section 4 shall inure to the benefit of the heirs, executors,
and administrators of any Indemnified Person.

                                                                    ----------

     NOW, THEREFORE, for the consideration herein stipulated, the parties hereby
agree as follows:

          1.   Management of the Retained Assets
               ---------------------------------

          (a) From and after the date hereof, the parties shall cooperate with
each other and shall continue to assist each other consistent with the
Contribution Agreement in seeking the consent or approval of the applicable
Governmental Authorities to the transfer of the Retained Assets to the Manager
from Central.

          (b)  From and after the Closing Date,
<PAGE>
 
          (i) The Manager shall operate and manage the Retained Assets until the
     earlier of (A) the transfer of the Retained Assets to the Manager pursuant
     to the Conveyance or (B) the dissolution of the Manager pursuant to the
     Operating Agreement of the Manager.

          (ii) Until such time as the Retained Assets are conveyed to the
     Manager, Central shall continue to own and exercise ultimate control over
     the operation thereof.  The Manager shall not, during the continuance of
     this Agreement, take any action inconsistent with the terms and provisions
     of this Agreement that would constitute (or fail to take any action
     inconsistent with the terms and provisions of this Agreement the effect of
     which failure would be to cause) (A) an impermissible change in control
     under the franchise or applicable state or local laws or regulations or (B)
     an impermissible transfer of a Federal Communications Commission ("FCC")
     license.

     2.   Duties of the Manager.  During the term of this Agreement, except as
          ---------------------                                               
set forth in Section 1, this Section 2 or Section 3, the Manager shall have all
requisite authority to manage the day-to-day operations of the Retained Assets
for the benefit of Central.  During the term of this Agreement, the Manager
agrees:

          (a) to be responsible for the negotiation, consummation and
performance of any and all agreements, leases, contracts, documents and other
instruments reasonably necessary or convenient for the management and operation
of the Retained Assets;

          (b) to supervise the collection of income and other amounts and the
payment of expenses (including but not limited to franchise fees) relating to
the Retained Assets and enforce the rights of Central as a creditor under any
contract in connection with the rendering of any service with respect to the
Retained Assets to the same extent as the Manager would enforce its own rights
as a creditor;

          (c) to implement and maintain such accounting and administrative
records, procedures and reports as shall be reasonably necessary to operate the
Retained Assets;

          (d) to purchase liability and other insurance reasonably necessary to
protect the Retained Assets and usual and customary for comparable businesses;
to name Central as an additional insured with respect to each such insurance
policy;

          (e) to be responsible for all personnel matters, and to provide,
manage and train all employees and other personnel reasonably necessary to
operate the Retained Assets;

          (f) to prepare status reports, financial reports and cash
disbursements reports relating to the operation of the Retained Assets;

          (g) to keep, in the name and for the account of Central, full and
adequate books of account and other records reflecting the results of operation
of the Retained Assets on an accrual basis, in accordance with generally
accepted accounting principles;


                                       2
<PAGE>
 
          (h) to prepare annual tax reports necessary for the operation of the
Retained Assets (other than Federal, state and local income tax returns relating
to Central), to prepare, as necessary, any reports and other documents required
to be filed with governmental and regulatory agencies (other than with respect
to income tax matters with respect to the operation of the Retained Assets), and
act as liaison with Federal, state and local governmental and regulatory
officials with respect thereto, and to provide Central on a timely basis all
information necessary to prepare its Federal, state and local income tax
returns;

          (i) to pay all expenditures incurred by the Manager in the ordinary
course of operating the Retained Assets;

          (j) to pay all expenses of the Retained Assets, including, but not
limited to, payroll and all other taxes;

          (k) to make all capital expenditures reasonably appropriate or
necessary to maintain operation of the Retained Assets as currently operated;

          (l) to manage and operate the Retained Assets in compliance in all
material respects with applicable law, including, not limited to, the
Communications Act of 1934, as amended, and all rules and regulations
promulgated thereunder, all applicable franchise requirements and all other
agreements relating to the Retained Assets;

          (m) to operate and manage the Retained Assets with the same level of
care as it operates cable television systems owned by the Manager.

     3.   Obligations of Central.  Notwithstanding anything in Section 1 or 2
          ----------------------                                             
hereof to the contrary (a) during the term of this Agreement, Central shall be
responsible for decisions affecting the operations of the Retained Assets,
including the matters referred to in Sections 1 and 2 (and including
particularly all financial and personnel matters), to the extent Central must
continue to be responsible for any such decisions under any agreement, including
any and all franchise agreements relating to the Retained Assets, or applicable
law, and (b) Central shall be entitled to control any tax investigation or audit
relating in any way to the Retained Assets to the extent it could affect any
taxes payable by Central for periods prior to the Closing.

     4.   Compensation of the Manager.  For its services pursuant to this
          ---------------------------                                    
Agreement, the Manager shall be entitled from and after the Closing to all
revenues attributable to the operations of the Retained Assets (the "Retained
Assets Revenue") for the period commencing at the Closing through the date that
the Manager ceases its operation and management of the Retained Assets in
accordance with Section 1 (b) (i) hereof (or such later date as the parties may
agree).

     5.   No Contributions by Central.  During the term of this Agreement,
          ---------------------------                                     
Central shall not be obligated to contribute any capital to or make any funds
available for the operation of or the obligations or liabilities relating to the
Retained Assets and the Manager shall be solely responsible for all expenses and
expenditures thereof.  Without limiting the generality of the foregoing, Central
will not be responsible for any compensation payable to the Manager; such
compensation shall be 


                                       3
<PAGE>
 
payable solely out of the Retained Assets Revenue as provided in Section 4
above. Nothing in this Agreement shall require the Manager to make any payments
for indebtedness of Central in respect of any Retained Assets.

     6.   Term of Agreement; Effect of Termination.  This Agreement shall
          ----------------------------------------                       
continue in full force and effect until the date that the Manager ceases its
operation and management of the Retained Assets in accordance with Section l(b)
(i) hereof.  Central shall pay to the Manager within 10 days of termination of
this Agreement all amounts due under Section 4 for months ended prior to the
date of termination and a prorated portion, based on days elapsed prior to
termination in the month of termination, of all amounts due under Section 4 for
the month including the date of termination.  To the extent that any amount
relating to the period prior to termination which would thereafter have become
due under Section 4 had this Agreement not been terminated, such amount shall be
paid to the Manager on the date it would have been paid had this Agreement not
been terminated.

     7.   Independent Contractor.  The Manager and Central are not partners or
          ----------------------                                              
joint venturers with each other with respect to the Retained Assets and nothing
herein shall be construed so as to make them such partners or joint venturers.
In fulfilling their obligations hereunder, the parties shall be independent
contractors with respect to one another and not the agent of the other for any
purpose.

     8.   Non-Assignability of Agreement.  Neither party shall have the right to
          ------------------------------                                        
assign this Agreement.

     9.   Waiver.  No waiver of any term, provision, or condition of this
          ------                                                         
Agreement, whether by conduct or otherwise, in any one or more instances, shall
be deemed or construed as a further and continuing waiver of any such term,
provision or condition, but any party hereto may waive its rights in any
particular instance by a written instrument of waiver.

     10.  Entire Agreement.  This Agreement, together with the Contribution
          ----------------                                                 
Agreement, represents the entire understanding of the parties hereto with
respect to the subject matter hereof, and may not be modified or amended, except
by a written instrument executed by each of the parties hereto designating
specifically the terms and provisions so modified and amended.

     11.  Choice of Law.  The internal laws of the State of New York shall
          -------------                                                   
govern this Agreement and the construction of any of its terms.

     12.  Counterparts.  This Agreement may be signed in one or more
          ------------                                              
counterparts, each of which shall be deemed an original, but all of which taken
together shall constitute one and the same instrument.

     13.  Notices.  Any notice, demand or request required or permitted to be
          -------

  The undersigned hereby acknowledges receipt of the Prospectus dated       ,
     (the "Prospectus") of Coaxial Communications of Central Ohio, Inc., an
Ohio corporation ("Coaxial"), and Phoenix Associates, a Florida general
partnership ("Phoenix" and together with Coaxial, the "Issuers"), and this
Letter of Transmittal (the "Letter of Transmittal"), that together constitute
the Issuers' offer (the "Exchange Offer") to exchange $1,000 in principal
amount of its 10% Senior Notes due 2006 (the "Exchange Notes"), which have
been registered under the Securities Act (as hereinafter defined) pursuant to
a Registration Statement, for each $1,000 in principal amount of its
outstanding 10% Senior Notes due 2006 (the "Notes"), of which $140,000,000
aggregate principal amount is outstanding. Capitalized terms used but not
defined herein have the meanings ascribed to them in the Prospectus.
 
  The undersigned hereby tenders the Notes described in Box 1 below (the
"Tendered Notes") pursuant to the terms and conditions described in the
Prospectus and this Letter of Transmittal. The undersigned is the registered
owner of all the Tendered Notes and the undersigned represents that it has
received from each beneficial owner of the Tendered Notes ("Beneficial
Owners") a duly completed and executed form of "Instruction to Registered
Holder and/or Book-Entry Transfer Facility Participant from Beneficial Owner"
accompanying this Letter of Transmittal, instructing the undersigned to take
the action described in this Letter of Transmittal.
<PAGE>
 
  Subject to, and effective upon, the acceptance for exchange of the Tendered
Notes, the undersigned hereby exchanges, assigns, and transfers to, or upon
the order of, the Issuers, all rights, title, and interest in, to and under
the Tendered Notes.
 
  Please issue the Exchange Notes exchanged for Tendered Notes in the name(s)
of the undersigned. Similarly, unless otherwise indicated under "Special
Delivery Instructions" below (Box 3), please send or cause to be sent the
certificates for the Exchange Notes (and accompanying documents, as
appropriate) to the undersigned at the address shown below in Box 1.
 
  The undersigned hereby irrevocably constitutes and appoints the Exchange
Agent as the true and lawful agent and attorney in fact of the undersigned
with respect to the Tendered Notes, with full power of substitution (such
power of attorney being deemed to be an irrevocable power coupled with an
interest), to (i) deliver the Tendered Notes to the Issuers or cause ownership
of the Tendered Notes to be transferred to, or upon the order of, the Issuers,
on the books of the registrar for the Notes and deliver all accompanying
evidences of transfer and authenticity to, or upon the order of, the Issuers
upon receipt by the Exchange Agent, as the undersigned's agent, of the
Exchange Notes to which the undersigned is entitled upon acceptance by the
Issuers of the Tendered Notes pursuant to the Exchange Offer, and (ii) receive
all benefits and otherwise exercise all rights of beneficial ownership of the
Tendered Notes, all in accordance with the terms of the Exchange Offer.
 
  The undersigned understands that tenders of Notes pursuant to the procedures
described in the caption "The Exchange Offer" in the Prospectus and in the
instructions hereto will constitute a binding agreement between the
undersigned and the Issuers upon the terms and subject to the conditions of
the Exchange Offer, subject only to withdrawal of such tenders on the terms
set forth in the Prospectus under the caption "The Exchange Offer--Withdrawal
of Tenders." All authority herein conferred or agreed to be conferred shall
survive the death or incapacity of the undersigned and any Beneficial
Owner(s), and every obligation of the undersigned or any Beneficial Owners
hereunder shall be binding upon the heirs, representatives, successors and
assigns of the undersigned and such Beneficial Owner(s).
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, exchange, assign and transfer the Tendered
Notes and that the Issuers will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges, encumbrances and adverse
claims when the Tendered Notes are acquired by the Issuers as contemplated
herein. The undersigned and each Beneficial Owner will, upon request, execute
and deliver any additional documents reasonably requested by the Issuers or
the Exchange Agent as necessary or desirable to complete and give effect to
the transactions contemplated hereby.
 
  The undersigned hereby represents and warrants that the information set
forth in Box 2 is true and correct.
 
  By accepting the Exchange Offer, the undersigned hereby represents and
warrants that (i) the Exchange Notes to be acquired by the undersigned and any
Beneficial Owner(s) in connection with the Exchange Offer are being acquired
by the undersigned and any Beneficial Owner(s) in the ordinary course of
business of the undersigned and any Beneficial Owner(s), (ii) the undersigned
and each Beneficial Owner are not participating, do not intend to participate,
and have no arrangement or understanding with any person to participate, in
the distribution of the Exchange Notes, (iii) except as otherwise disclosed in
writing herewith, neither the undersigned nor any Beneficial Owner is an
"affiliate," as defined in Rule 405 under the Securities Act, of the Issuers
or any of their subsidiaries and (iv) the undersigned and each Beneficial
Owner acknowledge and agree that any person participating in the Exchange
Offer with the intention or for the purpose of distributing the Exchange Notes
must comply with the registration and prospectus delivery requirements of the
Securities Act of 1933, as amended (together with the rules and regulations
promulgated thereunder, the "Securities Act"), in connection with a secondary
resale of the Exchange Notes acquired by such person and cannot rely on the
position of the Staff of the Securities and Exchange Commission (the
"Commission") set forth in the no-action letters that are discussed in the
section of the Prospectus entitled "The Exchange Offer." Each broker-dealer
that will receive Exchange Notes for its own account in exchange for Notes
that were acquired as a result of market-making activities or other trading
activities hereby acknowledges that it will deliver a Prospectus in connection
with any resale of such Exchange Notes; however, by so acknowledging and by
delivering a Prospectus, such broker-dealer is not deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.

                     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 "The 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
Company. 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 or hand delivery) 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.
 
   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
 
                                       7
<PAGE>
 
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 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 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
<PAGE>
 
   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.
 
  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.
 
  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 Company reserves 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.
 
  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
 
                                       9
<PAGE>
 
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."
