                                  ----------
 
   THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON      ,
                             1996, UNLESS EXTENDED
 
                                  ----------
 
  Cablevision Systems Corporation, a Delaware corporation (the "Company"),
hereby offers, upon the terms and subject to the conditions set forth in this
Prospectus and the accompanying letter of transmittal (the "Letter of
Transmittal," and together with this Prospectus, the "Exchange Offer"), to
exchange $100 aggregate liquidation preference of its Depositary Shares (the
"New Depositary Shares") each representing a one one-hundredth interest in a
share of its 11 1/8% Series M Redeemable Exchangeable Preferred Stock (the
"Series M Preferred Stock"), which have been registered under the Securities
Act of 1933, as amended (the "Securities Act"), pursuant to a Registration
Statement (as defined herein) of which this Prospectus constitutes a part, for
each $100 aggregate liquidation preference of its Depositary Shares (the "Old
Depositary Shares") each representing a one one-hundredth interest in a share
of the outstanding 11 1/8% Series L Redeemable Exchangeable Preferred Stock
(the "Series L Preferred Stock") of the Company. The New Depositary Shares and
the Old Depositary Shares are collectively referred to herein as the
"Depositary Shares".
 
  The Company will accept for exchange any and all Old Depositary Shares that
are validly tendered on or prior to 5:00 p.m., New York City time, on the date
the Exchange Offer expires, which will be      , 1996, unless the Exchange
Offer is extended to a date not later than       , 1996 (the "Expiration
Date"). Tenders of Old Depositary Shares may be withdrawn at any time prior to
5:00 p.m., New York City time, on the business day prior to the Expiration
Date, unless previously accepted for exchange. The Exchange Offer is not
conditioned upon any minimum principal amount of Old Depositary Shares being
tendered for exchange. However, the Exchange Offer is subject to certain
conditions which may be waived by the Company and to the terms and provisions
of the Registration Rights Agreement (as defined herein). See "The Exchange
Offer".
 
  The form and terms of the New Depositary Shares are the same in all material
respects as the form and terms of the Old Depositary Shares except that the New
Depositary Shares have been registered under the Securities Act and will not
contain terms restricting the transfer of such New Depositary Shares. Following
the completion of the Exchange Offer, none of the Depositary Shares will be
entitled to the benefits of the Registration Rights Agreement, relating to
contingent increases in the dividend rate provided for pursuant thereto. See
"The Exchange Offer".
 
INVESTMENT IN THE DEPOSITARY SHARES  INVOLVES SIGNIFICANT RISKS DISCUSSED UNDER
 "RISK  FACTORS"  ON  PAGE  18  WHICH  SHOULD  BE  CONSIDERED  BY  PROSPECTIVE
 INVESTORS.
 
  Dividends on the shares of Series M Preferred Stock represented by the New
Depositary Shares are payable out of legally available funds and are cumulative
from the most recent dividend payment date to which dividends on the Old
Depositary Shares were paid (the "Accrual Date"). Holders of Old Depositary
Shares whose Old Depositary Shares are
                                                        (Continued on next page)
 
                                  ----------
 
THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE  SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
  AND EXCHANGE COMMISSION OR ANY  STATE SECURITIES COMMISSION PASSED UPON THE
  ACCURACY  OR  ADEQUACY  OF  THIS  PROSPECTUS.  ANY  REPRESENTATION  TO  THE
   CONTRARY IS A CRIMINAL OFFENSE.
 
                                  ----------
 
                  The date of this Prospectus is       , 1996.
<PAGE>
 
(Continued from previous page)
accepted for exchange will be deemed to have waived the right to receive any
payment in respect of dividends on the Old Depositary Shares accumulated from
the Accrual Date to the date of the issuance of the New Depositary Shares.
Consequently, holders who exchange their Old Depositary Shares for New
Depositary Shares will receive the same dividend payment on the next dividend
payment date (expected to be July 1, 1996) that they would have received had
they not accepted the Exchange Offer, except that if such dividend is not paid
in cash, it will be paid in New Depositary Shares instead of Old Depositary
Shares. The Company paid dividends on April 1, 1996 with respect to the Old
Depositary Shares by issuing additional Old Depositary Shares (the "Dividend
Shares"). Dividend Shares may be exchanged for New Depositary Shares. Dividends
on the shares of Series M Preferred Stock represented by the New Depositary
Shares are payable quarterly in arrears on January 1, April 1, July 1 and
October 1 of each year, commencing July 1, 1996, accumulating from the Accrual
Date at the annual rate of 11 1/8% per New Depositary Share.
 
  Before April 1, 2001, dividends may, at the option of the Company, be paid in
cash or by issuing New Depositary Shares representing fully paid and
nonassessable shares of Series M Preferred Stock with an aggregate liquidation
preference equal to the amount of such dividends. On and after April 1, 2001,
dividends must be paid in cash. The Series M Preferred Stock has a liquidation
preference of $10,000 per share (equivalent to $100 per New Depositary Share)
plus accumulated and unpaid dividends thereon.
 
  Based on no-action letters issued by the staff of the Securities and Exchange
Commission (the "Commission") to third parties, the Company believes the New
Depositary Shares issued pursuant to the Exchange Offer may be offered for
resale, resold and otherwise transferred by holders thereof (other than a
"Restricted Holder," being (i) a broker-dealer who acquires such New Depositary
Shares directly from the Company to resell pursuant to Rule 144A or any other
available exemption under the Securities Act or (ii) a person that is an
affiliate of the Company within the meaning of Rule 405 under the Securities
Act), without compliance with the registration and prospectus delivery
provisions of the Securities Act provided that such New Depositary Shares are
acquired in the ordinary course of such holders' business and such holders have
no arrangements with any person to participate in the distribution of such New
Depositary Shares. Eligible holders wishing to accept the Exchange Offer must
represent to the Company that such conditions have been met. Each broker-dealer
that receives New Depositary Shares for its own account pursuant to the
Exchange Offer must acknowledge that it will deliver a prospectus in connection
with any resale of such New Depositary Shares. The Letter of Transmittal states
that by so acknowledging and by delivering a prospectus, a broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. This Prospectus, as it may be amended or supplemented from time
to time, may be used by a broker-dealer in connection with resales of New
Depositary Shares received in exchange for Old Depositary Shares where such Old
Depositary Shares were acquired by such broker-dealer as a result of market-
making activities or other trading activities. The Company has agreed that it
will make this Prospectus and any amendment or supplement to this Prospectus
available to any broker-dealer for use in connection with any such resale for a
period of 90 days from the date of this Prospectus, or such shorter period as
will terminate when all Old Depositary Shares acquired by broker-dealers for
their own accounts as a result of market-making activities or other trading
activities have been exchanged for New Depositary Shares and resold by such
broker-dealers. See "Plan of Distribution."
 
  The Company will not receive any proceeds from this offering, and no
underwriter is being utilized in connection with the Exchange Offer.
 
  THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF OLD DEPOSITARY SHARES IN ANY
JURISDICTION IN WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE
IN COMPLIANCE WITH THE SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.
 
  The New Depositary Shares are new securities for which there currently is no
public market. If a market for the New Depositary Shares should develop, the
New Depositary Shares could trade at a discount from their aggregate
liquidation preference. The Company does not intend to list the New Depositary
Shares on a national securities exchange or to apply for quotation of the New
Depositary Shares through the National Association of Securities Dealers
Automated Quotation System. There can be no assurance that an active public
market for the New Depositary Shares will develop.
 
  The Company has been advised by Bear, Stearns & Co. Inc., Merrill Lynch & Co.
and Morgan Stanley & Co. Incorporated that they intend to make a market in the
New Depositary Shares; however, such entities are under no obligation to do so
and any market making activities with respect to the New Depositary Shares may
be discontinued at any time.

information, financial statements and pro forma financial information appearing
elsewhere in this Prospectus or incorporated by reference herein. Investment in
the securities offered hereby involves significant risks. See "Risk Factors".
 
                                  THE COMPANY
 
  The Company is one of the largest operators of cable television systems in
the United States, with approximately 2,723,000 subscribers in 19 states as of
December 31, 1995 based on the number of basic subscribers in systems which the
Company manages and which it owns or in which it has investments. The Company
also has ownership interests in companies that produce and distribute national
and regional programming services and provide advertising sales services for
the cable television industry. The Company was formed in 1985 to effect a
reorganization of its predecessors.
 
CABLE TELEVISION
 
  The cable television systems that are majority owned and managed by the
Company (the "Company's cable television systems") served approximately
2,061,000 subscribers as of December 31, 1995 in New York, Ohio, Connecticut,
New Jersey, Michigan and Massachusetts. In addition, the Company has non-
majority investments in and manages cable television systems which served
approximately 662,000 subscribers as of December 31, 1995 in Alabama, Arkansas,
Florida, Illinois, Kansas, Kentucky, Maine, Massachusetts, Mississippi,
Missouri, New Jersey, New York, North Carolina, Oklahoma, Pennsylvania and
Tennessee. The Company's cable television systems have generally been
characterized by relatively high revenues per subscriber ($37.07 for December
1995) and ratios of premium service units to basic subscribers (1.9:1 for
December 1995). In calculating revenue per subscriber, the Company includes
only recurring service revenues and excludes installation charges and certain
other revenues such as advertising, pay-per-view and home shopping revenues.
 
PROGRAMMING SERVICES
 
  The Company conducts its programming activities through Rainbow Programming
Holdings, Inc. ("Rainbow Programming"), its wholly-owned subsidiary, and
through subsidiaries of Rainbow Programming in partnership with certain
unaffiliated entities, including National Broadcasting Company, Inc. ("NBC")
and Liberty Media Corporation. Rainbow Programming's businesses include eight
regional SportsChannel services, four national entertainment services (American
Movie Classics Company, Bravo Network, MuchMusic and the Independent Film
Channel), Rainbow News 12 (regional news services serving suburban areas
surrounding New York City) and the sports services of Prime SportsChannel
Networks (Prime Network and NewSport). Rainbow Programming also owns an
interest in Madison Square Garden Corporation.
 
ADVERTISING SERVICES
 
  Rainbow Advertising Sales Corporation sells advertising time to national,
regional and local advertisers on behalf of the Company's cable television
systems and the SportsChannel and Rainbow News 12 programming services, as well
as on behalf of unaffiliated cable television systems.

                               preference of $10,000 (equivalent to $100 per
                               New Depositary Share) will be issued in exchange
                               for each Old Depositary Share representing a one
                               one-hundredth interest in a share of Series L
                               Preferred Stock with an aggregate liquidation
                               preference of $10,000 (equivalent to $100 per
                               Old Depositary Share). As of the date hereof,
                               6,592,379 Old Depositary Shares representing
                               shares of Series L Preferred Stock with an
                               aggregate liquidation preference of $659,237,900
                               are issued and outstanding. The Company will

  Resale..................    The Company believes that the New Depositary
                               Shares issued pursuant to the Exchange Offer
                               generally will be freely transferable by the
                               holders thereof without registration or any
                               prospectus delivery requirement under the
                               Securities Act, except that a "dealer" or any of
                               the Company's "affiliates", as such terms are
                               defined under the Securities Act, that exchanges
                               Old Depositary Shares held for its own account
                               (a "Restricted Holder") may be required to
                               deliver copies of this Prospectus in connection
                               with any resale of New Depositary Shares (the
                               "Resale Depositary Shares") issued in exchange
                               for such Old Depositary Shares (the "Prospectus
                               Delivery Requirement"). See "The Exchange
                               Offer--General" and "Plan of Distribution".
 
  Expiration Date.........    5:00 p.m., New York City time, on      , 1996,
                               unless the Exchange Offer is extended to a date
                               not later than      , 1996, in which case the
                               term "Expiration Date" means the latest date and
                               time to which the Exchange Offer is extended.
                               The maximum period that the Exchange Offer will
                               remain in effect shall be from the date of this
                               Prospectus until the Expiration Date. See "The
                               Exchange Offer--Expiration Date; Extensions;
                               Amendments".
 
  Accumulated Dividends
   on the New Depositary
   Shares and the Old
   Depositary Shares......
                              Dividends on the shares of Series M Preferred
                               Stock represented by the New Depositary Shares

                                       6
<PAGE>
 
                               Date. Holders of Old Depositary Shares whose Old
                               Depositary Shares are accepted for exchange will
                               be deemed to have waived the right to receive
                               any payment in respect of dividends on the
                               Series L Preferred Stock represented by such Old
                               Depositary Shares accumulated from the Accrual
                               Date to the date of the issuance of the New
                               Depositary Shares. Consequently, holders who
                               exchange their Old Depositary Shares for New
                               Depositary Shares will receive the same dividend
                               payment on the next dividend payment date
                               (expected to be July 1, 1996) that they would
                               have received had they not accepted the Exchange
                               Offer, except that if such dividend is not paid
                               in cash, it will be paid by issuing New
                               Depositary Shares instead of Old Depositary
                               Shares. See "The Exchange Offer--Dividends on
                               the Series M Preferred Stock".
 
  Termination of the
   Exchange Offer.........    The Company may terminate the Exchange Offer if
                               it determines that its ability to proceed with
                               the Exchange Offer could be materially impaired
                               due to any legal or governmental action, any new
                               law, statute, rule or regulation or any
                               interpretation of the staff of the Commission of
                               any existing law, statute, rule or regulation or
                               if the Company reasonably deems it advisable to
                               terminate the Exchange Offer. Holders of Old
                               Depositary Shares will have certain rights
                               against the Company under the Registration
                               Rights Agreement should the Company fail to
                               consummate the Exchange Offer. See "The Exchange
                               Offer--Termination".
 
                               No federal or state regulatory requirements must
                               be complied with or approvals obtained in
                               connection with the Exchange Offer, other than
                               applicable requirements under federal and state
                               securities laws.

                               practicable to file a shelf registration
                               statement (the "Shelf Registration Statement")
                               covering resales of the Old Depositary Shares
                               and use its best efforts to cause the Shelf
                               Registration Statement to be declared effective
                               under the Securities Act.
 
                               In the event that the Exchange Offer is not
                               consummated or the Shelf Registration Statement
                               is not declared effective on or prior to the
                               240th calendar day following the date of
                               original issue of the Old Depositary Shares, the
                               dividend rate borne by the Series L Preferred
                               Stock shall be increased by one-quarter of

                               one percent per annum for the first 90 days
                               following such 240-day period. Such dividend
                               rate will increase by an additional one-quarter
                               of one percent per annum at the beginning of
                               each subsequent 90-day period, up to a maximum
                               aggregate increase of one percent per annum.

                               the effectiveness of the Shelf Registration
                               Statement, as the case may be, the dividend rate
                               borne by the Series L Preferred Stock will be
                               reduced to the original dividend rate. Dividends
                               on the Series M Preferred Stock will accumulate
                               at the original dividend rate accruing on the
                               Series L Preferred Stock.

                               plus accrued and unpaid interest thereon, out of
                               the net proceeds of a sale of Junior Stock to a
                               Strategic Equity Investor or a public offering
                               of Class A Common Stock, provided that following
                               such redemption at least $325,000,000 principal
                               amount of Exchange Debentures remains
                               outstanding. See "Description of New Depositary
                               Shares, Series M Preferred Stock and Exchange
                               Debentures".
 
  Subordination...........    The Exchange Debentures will be subordinated to
                               all existing and future Senior Indebtedness (as
                               defined) of the Company and will rank pari passu
                               with the Company's 10 3/4% Senior Subordinated
                               Debentures due 2004, 9 7/8% Senior Subordinated
                               Debentures due 2013, 9 7/8% Senior Subordinated
                               Debentures due 2023, 9 1/4% Senior Subordinated
                               Notes due 2005, 8 1/2% Convertible Subordinated
                               Debentures due 2007 (that may be issued in
                               exchange for the Series I Preferred Stock) and
                               11 3/4% Senior Subordinated Debentures due 2007
                               (that may be issued in exchange for the Series G
                               Preferred Stock and the Series H Preferred
                               Stock) (collectively, the "Existing
                               Debentures"). The amount of Senior Indebtedness
                               outstanding at December 31, 1995, adjusted to
                               give pro forma effect to the transactions
                               described under "Capitalization" and the
                               application of the net proceeds to the Company
                               from the offering of the Series L Preferred
                               Stock represented by Old Depositary Shares,
                               would have been approximately $620.2 million. At
                               December 31, 1995, the Company also had
                               outstanding $1,257.8 million of senior
                               subordinated indebtedness and obligations
                               (including $334.2 million of indebtedness of
                               subsidiaries guaranteed by the Company, included
                               in indebtedness of consolidated subsidiaries set
                               forth in the next sentence) that would have
                               ranked pari passu with the Exchange Debentures.
                               Also, at December 31, 1995, consolidated
                               subsidiaries of the Company had outstanding,
                               adjusted to give pro forma effect to the
                               transactions described under "Capitalization",
                               approximately $1,206.2 million of indebtedness
                               which, insofar as the assets of those
                               subsidiaries are concerned, would have been
                               effectively senior to the Exchange Debentures.
 
  Certain Restrictions....    The Indenture for the Exchange Debentures, among
                               other things, contains restrictions (with
                               certain exceptions) on the ability of the
                               Company and its Restricted Subsidiaries (as
                               defined) to incur additional indebtedness, make
                               certain dividend payments or payments to redeem
                               or retire capital stock, invest in Unrestricted
                               Subsidiaries (as defined) or affiliates, engage
                               in certain transactions with affiliates and
                               merge or consolidate with or transfer all or
                               substantially all of their assets to another
                               entity. The Indenture also prohibits the Company
                               from issuing any indebtedness that is senior in
                               right of payment to the Exchange Debentures and
                               expressly subordinate in right of payment to any
                               other indebtedness of the Company.

- --------
(1) The consolidated statement of operations, balance sheet and statistical
    data reflect (i) the deconsolidation of A-R Cable Services, Inc. ("A-R
    Cable"), effective as of January 1, 1992, as a result of the restructuring
    of A-R Cable, (ii) the acquisition of Cablevision of New York City
    ("Cablevision of NYC"), effective as of July 10, 1992, and (iii) various
    acquisitions of cable television systems and other businesses during the
    periods presented. (See "Business--Cable Television Operations" in the Form
    10-K and "Condensed Pro Forma Consolidated Financial Information" herein.)
    Acquisitions made by the Company during the periods presented were
    accounted for under the purchase method of accounting and, accordingly, the
    acquisition costs were allocated to the net assets acquired based on their
    fair value, except for the acquisition of partnership interests in
    Cablevision of NYC from Charles F. Dolan and entities affiliated with him,
    which were recorded at Mr. Dolan's and such entities' historical costs.
    Acquisitions are reflected in the consolidated statement of operations,
    balance sheet and statistical data from the time of acquisition. Certain
    reclassifications have been made to the 1991 and 1990 financial statement
    amounts to conform to the 1992 presentation.
(2) The Company recorded a one-time charge in the first quarter of 1994 to
    provide for employee severance and related costs resulting from a
    restructuring of its operations.
(3) In 1992, the Company recognized a $50.0 million loss in connection with
    Rainbow Programming's commitment in respect of its venture with NBC
    relating to the 1992 Summer Olympics, which the Company paid in January
    1993.
(4) In connection with the 1992 V Cable Reorganization (as defined under "The
    Company--Cable Television"), the Company redeemed A-R Cable's redeemable
    preferred stock on May 11, 1992, incurring a loss of $20 million.
(5) In connection with the 1992 V Cable Reorganization, the Company wrote off
    approximately $7.5 million of deferred financing costs related to the debt
    of V Cable, Inc. Also, a portion of the Company's deferred financing costs
    of approximately $4.8 million in 1992 and $1.0 million in 1993, related to
    the replacement of bank debt with subordinated debt, were written off. In
    October 1994, the Company entered into a new bank credit agreement and
    redeemed $200 million of its reset debentures. The related deferred
    financing costs and unamortized discount relating to each were written off
    (the portions relating to Cablevision of NYC and Cablevision of New Jersey
    amounting to $3.2 million were written off in 1995) and approximately $2.0
    million in redemption fees were incurred in connection with the redemption
    of the reset debentures. In January 1995, Rainbow Programming amended its
    credit agreement to refinance its existing borrowings and to provide funds
    for the acquisition of SportsChannel (New York) Associates and Rainbow News
    12 Company, resulting in an approximately $2.3 million write-off of
    deferred financing costs.
(6) On September 26, 1995, the Company issued 2.5 million shares of the Old
    Preferred Stock.
(7) Homes passed is based upon homes passed by cable actually marketed and does
    not include multiple dwelling units passed by the cable plant that are not
    connected to it.
(8) Basic penetration represents basic service subscribers at the end of the
    period as a percentage of homes passed at the end of the period.
(9) Based on recurring service revenues, excluding installation charges and
    certain other revenues such as advertising, pay-per-view and home shopping
    revenues, for the last month of the period, divided by average basic
    subscribers for that month.

                                  RISK FACTORS
 
  Purchase of the New Depositary Shares representing the Series M Preferred
Stock offered hereby (the "Offering") involves various risks, including the
following principal factors, which, together with the other matters set forth
herein or incorporated by reference herein, should be carefully considered by
prospective investors.
 
  Substantial Indebtedness and High Degree of Leverage. The Company has
incurred substantial indebtedness, primarily to finance acquisitions and
expansion of its operations and, to a lesser extent, for investments in and
advances to affiliates. The Company's consolidated debt plus the Series G
Preferred Stock aggregated approximately $3.4 billion at December 31, 1995
($3.7 billion on a pro forma basis after giving effect to the transactions
described under "Capitalization") with varying maturities to 2023, including an
aggregate of approximately $808.6 million ($702.1 million on a pro forma basis
after giving effect to the transactions described under "Capitalization")
maturing on or prior to December 31, 2000. See Note 4 of Notes to the
Consolidated Financial Statements.
 
  Net Losses and Stockholders' Deficit. The Company reported net losses for the
years ended December 31, 1995, 1994 and 1993 of $317.5 million, $315.2 million
and $246.8 million, respectively. At December 31, 1995, the Company had a
stockholders' deficiency of $1.9 billion. The losses primarily reflect high
levels of interest expense and depreciation and amortization charges relating
to the depreciation of assets obtained through, and debt incurred to finance,
acquisitions. Interest expense and depreciation and amortization charges
remained at a high level throughout 1993, 1994 and 1995 and will continue at
high levels in 1996 and future years as a result of previously completed,
pending and future acquisitions, expected capital expenditures and additional
investments in the Company's programming operations. The Company expects to
continue incurring substantial losses for at least the next several years. See
"Management's Discussion and Analysis--Liquidity and Capital Resources".
 
  Need for Additional Financing. The Company's business requires substantial
investment on a continuing basis to finance capital expenditures and related
expenses for, among other things, upgrade of the Company's cable plant
(including the need to make cable system upgrades mandated by franchise
authorities), the offering of new services and the servicing, repayment or
refinancing of its indebtedness. The Company will require significant
additional financing, through debt and/or equity issuances, to meet its capital
expenditure plans and to pay its debt and preferred stock obligations. There
can be no assurance that the Company will be able to issue additional debt or
obtain additional equity capital on satisfactory terms, or at all, to meet its
future financing needs. See "Management's Discussion and Analysis--Liquidity
and Capital Resources".
 
  Future Capital Expenditures and Programming Commitments. The Company's cable
systems have commitments for capital expenditures, including major system
upgrades, which will involve substantial expenditures over the next several
years. In addition, the Company, through Rainbow Programming, has entered into
numerous contracts relating to cable television programming, including rights
agreements with professional and other sports teams. These contracts typically
require substantial payments over extended periods of time. See Note 11 of
Notes to Consolidated Financial Statements for a discussion of commitments.
 
  Rainbow Programming has the right to acquire interests in MSG Holdings from
ITT sufficient to equalize the interests of ITT and Rainbow Programming in MSG
Holdings by making certain scheduled payments totalling $250 million (plus
interest on any unpaid portion thereof) on specified dates up to and including
March 17, 1997. See "The Company--Programming Services". The Company and
Rainbow Programming may fund the interest payments on the unpaid portion of the
$250 million amount required to equalize the interests of ITT and Rainbow
Programming in MSG Holdings from available cash balances or amounts borrowed
under the Company's principal bank credit agreement (the "Credit Agreement").
Accordingly, the Company funded an approximate $29 million interest payment on
March 11, 1996 from funds available under the Credit Agreement. The Company has
not yet identified specific funding sources for the up to $250 million that
could be required in connection with the ITT/MSG Holdings transactions. The
Company also has a commitment to fund annual payments to Charles F. Dolan
related to Cablevision of
 
                                       18
<PAGE>
 
New York City ("Cablevision of NYC"). See "Business--Consolidated Cable
Affiliates--Cablevision of New York City" and "Business--Programming
Operations" in the Form 10-K and "Management's Discussion and Analysis--
Liquidity and Capital Resources".
 
  Intangible Assets. The Company had total assets at December 31, 1995 of
approximately $2.5 billion, of which approximately $1.0 billion were intangible
assets, principally franchises, affiliation agreements, excess cost over fair
value of net assets acquired, deferred financing, acquisition and other costs
and deferred interest expense. It is possible that no cash would be recoverable
from the voluntary or involuntary sale of these intangible assets.
 
  Losses on Investments in and Advances to Certain Affiliates. The Company has
made investments in and advances to certain affiliates of which Charles F.
Dolan has substantial ownership interests. At December 31, 1995, advances (less
applicable reserves) to one such affiliate, Atlantic Cable Television
Publishing Corporation ("Atlantic Publishing"), aggregated approximately $16.7
million. Because Mr. Dolan has a substantial interest in Atlantic Publishing,
an inherent conflict of interest exists with respect to such advances. There
can be no assurances that such advances and any amounts accrued with respect
thereto will be fully recovered or that conflicts of interest will not arise
with respect to the recovery of such amounts.
 
  Atlantic Publishing holds a minority equity interest and a debt interest in a
company that publishes cable television guides which are offered to the
Company's subscribers and to other unaffiliated cable television operators. As
of December 31, 1995, the Company had advanced an aggregate of $16.7 million to
Atlantic Publishing, of which approximately $0.5 million was repaid during
1993, $0.6 million was repaid during 1994 and approximately $1.0 million was
repaid during 1995. The Company has written off all advances to Atlantic
Publishing other than approximately $3.1 million. Atlantic Publishing is owned
by a trust for certain Dolan family members; however, the Company has the
option to purchase Atlantic Publishing for an amount equal to the owner's net
investment therein plus interest. The current owner has only a nominal
investment in Atlantic Publishing. See "Business--Other Affiliates--Atlantic
Publishing" in the Form 10-K.
 
  On December 15, 1995, the Company consummated the acquisition of Cablevision
of Boston. In connection with the acquisition, all the subordinated advances
that the Company had made to Cablevision of Boston became intercompany
indebtedness. As part of the acquisition of Cablevision of Boston, the Company
entered into an agreement with Mr. Dolan with respect to Mr. Dolan's 0.5%
general partnership interest in Cablevision of Brookline Limited Partnership
("Cablevision of Brookline"), a partnership affiliated with Cablevision of
Boston. The Company acquired the remaining 99.5% of the partnership interests
in Cablevision of Brookline in the acquisition of Cablevision of Boston. Under
the agreement, the Company has a right of first refusal to acquire Mr. Dolan's
0.5% general partnership interest and a right to acquire such interest on the
earlier to occur of Mr. Dolan's death or January 1, 2002 at the greater of
$10,000 or the book value of such interest at such date. Mr. Dolan's estate has
the right to put the interest to the Company at the same price. Additionally,
in the event of a change of control of the Company or Cablevision of Brookline,
Mr. Dolan will have the right to put his 0.5% general partnership interest in
Cablevision of Brookline to the Company at the greater of (i) prices declining
from $3.9 million for the year ended December 15, 1996 to $10,000 for the year
ended December 15, 2002 and (ii) the book value of such interest on the date of
transfer.
 
  See "Business--Consolidated Cable Affiliates--Cablevision of New York City"
in the Form 10-K for a discussion of the Company's acquisition of substantially
all of Charles F. Dolan's interest in Cablevision of NYC, which was consummated
as described therein in July 1992.
 
  Voting Control by Majority Stockholders; Disparate Voting Rights. As of
December 31, 1995, Charles F. Dolan beneficially owned and possessed sole
voting power with respect to 292,007 shares or 2.1% of the Company's
outstanding Class A Common Stock and 2,346,281 shares or 20.3% of the Company's
outstanding Class B common stock (the "Class B Common Stock" and, collectively
with the Class A Common Stock, the "Common Stock"). In addition, as of December
31, 1995, an aggregate of 4,000,000
 
                                       19
<PAGE>
 
shares or 34.6% of the outstanding Class B Common Stock were held by two
Grantor Retained Annuity Trusts (the "GRA Trusts") established by Mr. Dolan for
estate planning purposes. Mr. Dolan may be deemed to have beneficial ownership
of the shares of Class B Common Stock held by the GRA Trusts due to his right
to reacquire the Class B Common Stock held by the GRA Trusts by substituting
other property of equivalent value, but, until such event, each of the GRA
Trusts, through their co-trustees (who are family members of Mr. Dolan) has the
power to vote and dispose of the shares of Class B Common Stock held by the GRA
Trusts. As a result of his beneficial ownership of the shares held by the GRA
Trusts, as of December 31, 1995, Mr. Dolan beneficially owned 292,007 shares or
2.1% of the Company's outstanding Class A Common Stock and 6,346,281 shares or
54.8% of the Company's outstanding Class B Common Stock. On a combined basis,
these shares represented 25.7% of the total number of shares of both classes of
Common Stock and 49.1% of the total voting power of the classes. Other trusts
established by Mr. Dolan for the benefit of certain Dolan family members, and
as to which Mr. Dolan disclaims beneficial ownership, owned, as of December 31,
1995, an additional 500,000 shares of Class A Common Stock or 3.5% of the Class
A Common Stock and 5,225,928 shares of the Class B Common Stock, or 45.2% of
the Class B Common Stock and 40.6% of the total voting power of all classes of
the Common Stock. As a result of this stock ownership, Dolan family members
have the power to elect all the directors subject to election by holders of the
Class B Common Stock, which directors constitute 75% of the entire Board of
Directors of the Company. Moreover, because holders of Class B Common Stock are
entitled to ten votes per share while holders of Class A Common Stock are
entitled to one vote per share, Dolan family members may control stockholder
decisions on matters in which holders of Class A and Class B Common Stock vote
together as a class. These matters include the amendment of certain provisions
of the Company's certificate of incorporation (the "Certificate of
Incorporation") and the approval of fundamental corporate transactions,
including mergers. In addition, because the affirmative vote or consent of the
holders of at least 66 2/3% of the outstanding shares of the Class B Common
Stock, voting separately as a class, is required to approve (i) the
authorization or issuance of any additional shares of Class B Common Stock and
(ii) any amendment, alteration or repeal of any of the provisions of the
Certificate of Incorporation of the Company which adversely affects the powers,
preferences or rights of the Class B Common Stock, Dolan family members also
have the power to prevent such issuance or amendment. The voting rights of the
Class B Common Stock beneficially owned by Mr. Dolan will not be modified as a
result of any transfer of legal or beneficial ownership thereof.
 
  Restrictive Covenants. The Company's Credit Agreement and certain of the
Company's other debt instruments contain various financial and operating
covenants which, among other things, require the maintenance of certain
financial ratios and restrict the Company's ability to borrow funds from other
sources and to utilize funds for various purposes, including investments in
certain subsidiaries. Violation of the covenants in the Credit Agreement could
result in a default under the Credit Agreement which would permit the bank
lenders thereunder to restrict the Company's ability to borrow undrawn funds
under the Credit Agreement and to accelerate the maturity of borrowings
thereunder. See "Management's Discussion and Analysis--Liquidity and Capital
Resources".
 
  Conflicts of Interest. Charles F. Dolan and trusts for Dolan family interests
have varying economic interests in the Company's affiliates. Mr. Dolan and
other officers and directors of the Company are also officers and directors of
affiliated companies. Such officers and directors of the Company devote such
time to the business of the Company as is reasonably required; however, they
have other responsibilities which require various amounts of their time and
which could conflict with their duties to the Company.
 
  Risks Related to Regulation. The Company's cable television operations may be
adversely affected by government regulation, the impact of competitive forces
and technological changes. In 1992, Congress enacted the 1992 Cable Act, which
represented a significant change in the regulatory framework under which cable
television systems operate. In April 1993 and February 1994, the FCC ordered
reductions in cable television rates. In June 1995, a Federal appeals court
upheld the material aspects of the FCC's rate regulation scheme. Congress has
enacted legislation (the "Telecommunications Act of 1996") that relaxes the
regulation
 
                                       20
<PAGE>
 
of cable television rates. See "Business--Cable Television Operations--
Competition" and "Business--Cable Television Operations--Regulation" in the
Form 10-K.
 
  Risk of Competition. Cable operators compete with a variety of distribution
systems, including broadcast television stations, multichannel multipoint
distribution services ("MMDS"), satellite master antenna systems ("SMATV"),
direct broadcast satellite systems ("DBS"), and private home dish earth
stations. For example, CAI Wireless Systems, Inc., an MMDS operator, has
received investments from Bell Atlantic Corporation and NYNEX Corporation and
owns operating systems or spectrum rights in a significant portion of the
Company's systems. In addition, three DBS systems are now operational in the
United States and recently AT&T Corp. announced an investment in Hughes
Electronics Corp.'s DirecTv Inc. A venture of MCI and News Corp. recently
acquired the rights to launch and operate a fourth DBS system. The 1992 Cable
Act prohibits a cable programmer that is owned by or affiliated with a cable
operator (such as Rainbow Programming) from unreasonably discriminating among
or between cable operators and other multichannel video distribution systems
with respect to the price, terms and conditions of sale or distribution of the
programmer's service and from unreasonably refusing to sell service to any
multichannel video programming distributor. Cable systems also compete with the
entities that make videotaped movies and programs available for home rental.
The 1992 Cable Act regulates the ownership by cable operators of MMDS and
SMATV. Under the Telecommunications Act of 1996, these cross-ownership
provisions do not apply to any cable operator in a franchise area in which a
cable operator faces competition from video programming distributors meeting
certain statutory requirements. In July 1992, the FCC voted to authorize
additional competition to cable television by video programmers using broadband
common carrier facilities constructed by telephone companies. The FCC allowed
telephone companies to take ownership interests of up to 5% in such
programmers. The FCC also reaffirmed an earlier holding, upheld on appeal by a
Federal appeals court, that programmers using such a telephone company-provided
"video dialtone" system would not need to obtain a state or municipal
franchise. Several telephone companies have sought approval from the FCC to
build such "video dialtone" systems. Such a system has been proposed in several
communities in which the Company currently holds a cable franchise and several
of such systems have been approved by the FCC. The Telecommunications Act of
1996 repeals the "video dialtone" rules, but gives telephone companies (and
cable companies, to the extent permitted by the FCC) the option of providing
video programming to subscribers through "open video systems" that closely
resemble video dialtone systems and that would not require a local cable
franchise. Additional competition to cable systems is possible if the FCC
authorizes the licensing of local multipoint distribution services ("LMDS").
The FCC has proposed to license this type of service to providers.
 
  Competition from Telephone Companies. The 1984 Cable Act bars co-ownership of
telephone companies and cable television systems operating in the same service
areas ("cable-telco cross-ownership prohibition"). Numerous Federal district
courts have held this prohibition to be unconstitutional. Several of these
decisions have been upheld on appeal and a number of other decisions are
pending on appeal in various Federal appellate courts. The United States
Supreme Court is expected to rule on the constitutionality of the prohibition
during the 1995-96 term. Neither the 1984 Cable Act nor the 1992 Cable Act bars
a telephone company from acquiring cable systems outside its telephone service
area, and several Regional Bell operating companies have purchased or made
investments in cable systems. The Telecommunications Act of 1996 permits a
telephone company to provide video programming directly to subscribers in its
telephone service territory, subject to certain regulatory requirements, but
generally prohibits a telephone company from acquiring an in-region cable
operator, except in certain small markets under certain circumstances. See
"Business--Cable Television Operations--Regulation" in the Form 10-K.
 
  Risk of Non-Exclusive Franchises and Franchise Renewals. The Company's cable
television systems are operated primarily under nonexclusive franchise
agreements with local government franchising authorities, in some cases with
the approval of state cable television authorities. The Company's business is
dependent on its ability to obtain and renew its franchises. Although the
Company has never lost a franchise as a result of a failure to obtain a
renewal, its franchises are subject to non-renewal or termination under certain
circumstances. In certain cases, franchises have not been renewed at expiration
and the Company operates
 
                                       21
<PAGE>
 
under temporary licenses while negotiating renewal terms with the franchising
authorities. See "Business--Cable Television Operations--Franchises" in the
Form 10-K.
 
 Risks Related to the Securities.
 
  Absence of Public Market. The New Depositary Shares are new securities for
which there currently is no market. Although Bear, Stearns & Co. Inc., Merrill
Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co.
Incorporated, the initial purchasers of the Old Depositary Shares
(collectively, the "Initial Purchasers"), have informed the Company that they
currently intend to make a market in the Old Depositary Shares, the New
Depositary Shares and, if issued, the Exchange Debentures, they are not
obligated to do so and any such market making may be discontinued at any time
without notice. Accordingly, there can be no assurance as to the development or
liquidity of any market for the Old Depositary Shares, the New Depositary
Shares and, if issued, the Exchange Debentures. The Company does not intend to
apply for listing of the New Depositary Shares or, if issued, the Exchange
Debentures on any securities exchange or for quotation through the National
Association of Securities Dealers Automated Quotation System.
 
  Restrictions on Company's Ability to Pay Dividends on the Series L Preferred
Stock and the Series M Preferred Stock. Certain of the Company's debt
instruments contain covenants that restrict the Company's ability to pay, or
may prevent the payment of, dividends on the Company's preferred stock,
including the Series L Preferred Stock and the Series M Preferred Stock. In
addition, under Delaware law, dividends on capital stock may only be paid from
"surplus" or if there is no surplus from the corporation's net profits for the
then current or the preceding fiscal year. The Company does not anticipate
having net profits for the foreseeable future and its ability to pay dividends
on the Series L Preferred Stock and the Series M Preferred Stock will require
the availability of adequate "surplus", which is defined as the excess, if any,
of the Company's net assets (total assets less total liabilities) over its
capital (generally the par value of its issued capital stock). As of December
31, 1995, the Company's total liabilities, including deficit investment in
affiliates and Series G Preferred Stock, exceeded its total assets by $1.9
billion. Accordingly, in connection with dividend payments on the Series L
Preferred Stock or the Series M Preferred Stock, the Company's Board of
Directors will have to determine that the Company has adequate surplus on the
basis of valuations of the Company's assets at higher amounts than are
reflected in the Company's financial statements. There can be no assurance that
the Company's Board of Directors will be able to make such determination and
that adequate surplus will be available to pay dividends on the Series L
Preferred Stock or the Series M Preferred Stock.
 
  Certain Federal Income Tax Consequences. The Company believes that it does
not presently have any current or accumulated earnings and profits as
determined under United States federal income tax principles and that it is
unlikely to have current or accumulated earnings and profits for the
foreseeable future. As a result, until such time as the Company does have
earnings and profits, distributions on the New Depositary Shares will be
treated as a nontaxable return of capital and will be applied against and
reduce the adjusted tax basis of the New Depositary Shares in the hands of each
holder (but not below zero), thus increasing the amount of any gain (or
reducing the amount of any loss) which would otherwise be realized by such
holder upon the disposition of such New Depositary Shares. Consequently,
distributions with respect to the New Depositary Shares will not qualify as
dividends for federal income tax purposes and, as a result, will not be
eligible for the dividends-received deduction.
 
                                  THE COMPANY
 
  The Company is one of the largest operators of cable television systems in
the United States, with approximately 2,723,000 subscribers in 19 states as of
December 31, 1995 based on the number of basic subscribers in systems which the
Company manages and which it owns or in which it has investments. The Company
also has ownership interests in companies that produce and distribute national
and regional programming services and provide advertising sales services for
the cable television industry.
 
                                       22
<PAGE>
 
  For financing purposes, the Company is structured as a restricted group
(collectively, the "Restricted Group") and an unrestricted group of
subsidiaries. The Restricted Group consists of Cablevision Systems Corporation
and certain of its subsidiaries, including Cablevision of NYC and, as of
December 15, 1995, a subsidiary holding the cable television assets previously
a part of Cablevision of Boston Limited Partnership ("Cablevision of Boston").
The unrestricted group of subsidiaries consists primarily of V Cable, Inc. ("V
Cable"), Cablevision MFR, Inc. ("Cablevision MFR" and, collectively with V
Cable, "Unrestricted Cable") and Rainbow Programming Holdings, Inc., (including
Rainbow Advertising Sales Corporation ("Rainbow Advertising"), American Movie
Classics ("AMCC") and SportsChannel Associates (New York) ("SportsChannel New
York")) (collectively, "Rainbow Programming"). In addition, the Company has an
unrestricted group of investments, consisting of investments in A-R Cable
Services, Inc. ("A-R Cable"), U.S. Cable Television Group, L.P. ("U.S. Cable"),
Cablevision of Framingham Holding, Inc. ("CFHI"), A-R Cable Partners and
Cablevision of Newark. The Company's unrestricted subsidiaries and investments
are collectively referred to herein as the "Unrestricted Group". The Restricted
Group and each member of the Unrestricted Group that operates cable television
systems are individually and separately financed. The indebtedness of V Cable
and A-R Cable is non-recourse to the Company, other than with respect to the
capital stock of such entities owned by the Company. Rainbow Programming's cash
requirements have been financed to date by the Restricted Group, by sales of
equity interests in the programming businesses and, as set forth below under
"--Programming Services", through separate external debt financing. See
"Management's Discussion and Analysis--Liquidity and Capital Resources" for a
discussion of the restrictions on investments by the Restricted Group and
certain other matters.
 
STRATEGY
 
  The Company's strategy has been to concentrate its cable television systems
in and around two major metropolitan areas, New York City and Cleveland, Ohio,
with a view to being the largest cable provider in each of these markets; to
maximize its revenue per subscriber through the use of "tiered" packaging
strategies for marketing premium services; to develop and promote niche
programming services; and to remain an industry leader in upgrading the
technological capabilities of its systems.
 
  The Company believes that its cable television systems on Long Island, New
York comprise the largest contiguous group of cable television systems under
common ownership in the United States (measured by number of subscribers). By
developing systems in and around major metropolitan areas, including expansion
through acquisitions in areas in which the Company has existing systems, the
Company has been able to realize economies of scale in the operation and
management of its systems, and capitalize on opportunities to create and market
programming of regional interest.
 
  Through the current and planned upgrade of its cable plant, including the
utilization of fiber optic cable and associated electronics, the Company is
seeking to significantly increase its analog channel capacity and add new
digital channel capacity that will facilitate the development of such adjunct
new businesses as information services, interactive services, including
Internet access, video on demand, near video on demand, residential telephony
and commercial telephony. To successfully roll out these adjunct new businesses
significantly beyond the initial development phases, the Company will require
additional capital from the sale of equity in the capital markets or to a
strategic investor.
 
CABLE TELEVISION
 
  The cable television systems that are majority owned and managed by the
Company (the "Company's cable televisions systems") served approximately
2,061,000 subscribers as of December 31, 1995 in New York, Ohio, Connecticut,
New Jersey, Michigan and Massachusetts. In addition, the Company has non-
majority investments in and manages cable television systems which served
approximately 662,000 subscribers as of December 31, 1995 in Alabama, Arkansas,
Florida, Illinois, Kansas, Kentucky, Maine, Massachusetts, Mississippi,
Missouri, New Jersey, New York, North Carolina, Oklahoma, Pennsylvania and
Tennessee. The Company's cable television systems have generally been
characterized by relatively high revenues per
 
                                       23
<PAGE>
 
subscriber ($37.07 for December 1995) and ratios of premium service units to
basic subscribers (1.9:1 for December 1995). In calculating revenue per
subscriber, the Company includes only recurring service revenues and excludes
installation charges and certain other revenues such as advertising, pay-per-
view and home shopping revenues.
 
  The cable television operations in the Restricted Group served approximately
1,512,000 subscribers as of December 31, 1995, primarily on Long Island, New
York, in New York City, in Connecticut (principally Fairfield County), in
northern New Jersey, in Westchester County, New York and in Cleveland, Ohio.
The revenue per subscriber and ratio of premium service units to basic
subscribers for cable television systems in the Restricted Group for December
1995 were $38.82 and 2.2:1, respectively.
 
  The cable television operations in Unrestricted Cable served approximately
549,000 subscribers as of December 31, 1995 and are conducted through the
Company's unrestricted subsidiaries, V Cable and Cablevision MFR, and through
its unrestricted investments, consisting of A-R Cable, U.S. Cable, CFHI, A-R
Cable Partners and Cablevision of Newark. The revenue per subscriber and ratio
of premium service units to basic subscribers for the Company's unrestricted
subsidiaries for December 1995 were $32.45 and 1.1:1, respectively.
 
  In August 1994, Cablevision MFR, a wholly-owned subsidiary of the Company,
acquired substantially all of the assets of Monmouth Cablevision Associates
("Monmouth Cable") and Riverview Cablevision Associates, L.P. ("Riverview
Cable"), consisting of cable television systems in New Jersey. Also in August
1994, CFHI, a corporation jointly owned by the Company and E.M. Warburg Pincus
Investors, L.P., acquired substantially all of the assets of Framingham
Cablevision Associates Limited Partnership ("Framingham Cable"), consisting of
a cable television system in Massachusetts. Additionally, in June 1994, a
partnership comprised of subsidiaries of the Company and E.M. Warburg, Pincus &
Co. Inc. completed the purchase of certain assets of Nashoba Communications, a
group of three limited partnerships that operate three cable television systems
in Massachusetts.
 
  V Cable was formed by the Company in February 1989, principally in the
suburbs of Cleveland, Ohio and on Long Island. As described under "Business--
Consolidated Cable Affiliates--V Cable" in the Form 10-K, the Company
consummated a significant restructuring and reorganization involving V Cable
and U.S. Cable (the "1992 V Cable Reorganization") on December 31, 1992. See
also "Recent Developments--V Cable Transactions" in the Form 10-K for a
description of certain transactions involving V Cable.
 
PROGRAMMING SERVICES
 
  The Company conducts its programming activities through Rainbow Programming,
its wholly-owned subsidiary and member of the Unrestricted Group, and through
subsidiaries of Rainbow Programming in partnership with certain unaffiliated
entities, including National Broadcasting Company, Inc. ("NBC") and Liberty
Media Corporation ("Liberty"). Rainbow Programming's businesses include eight
regional SportsChannel services, four national entertainment services, AMCC,
Bravo Network ("Bravo"), MuchMusic ("MM") and the Independent Film Channel
("IFC")), Rainbow News 12 (regional news services serving suburban areas
surrounding New York City) and the sports services of Prime SportsChannel
Networks (Prime Network and NewSport). Rainbow Programming also owns an
interest in Madison Square Garden Corporation ("MSG"). Rainbow Programming's
SportsChannel services provide regional sports programming to the New York,
Philadelphia, New England, Chicago, Cincinnati, Cleveland, San Francisco and
Florida areas. AMCC is a national program service featuring classic, unedited
and non-colorized films from the 1930s through the 1970s. Bravo is a national
program service offering international films and performing arts programs,
including jazz, dance, classical music, opera and theatrical programs. See
"Business--Programming Operations--General" in the Form 10-K. MM is a Canadian
music service featuring music primarily from Canadian artists. IFC is a
national program service that airs independent films made outside the
traditional Hollywood system.
 
                                       24
<PAGE>
 
  In March 1995, MSG Holdings, L.P. ("MSG Holdings"), a partnership among
subsidiaries of Rainbow Programming and subsidiaries of ITT Corporation, a
Delaware corporation ("ITT"), acquired the business and assets of MSG in a
transaction in which MSG merged with and into MSG Holdings. MSG owns the
Madison Square Garden Arena and the adjoining Paramount Theater, the New York
Rangers professional hockey team, the New York Knicks professional basketball
team and the Madison Square Garden Network, a sports programming network with
over five million subscribers. The purchase price paid by MSG Holdings for MSG
was $1,009.1 million. The name of MSG Holdings has been changed to Madison
Square Garden, L.P.
 
  MSG Holdings funded the purchase price of the acquisition through (i)
borrowings of $289.1 million under a $450 million credit agreement among MSG
Holdings, various lending institutions and Chemical Bank as administrative
agent, (ii) an equity contribution from Rainbow Programming of $110 million,
and (iii) an equity contribution from ITT of $610 million. ITT, Rainbow
Programming and the Company are parties to an agreement made as of August 15,
1994 (as amended, the "Bid Agreement") that, as amended, provides Rainbow
Programming the right to acquire interests in MSG Holdings from ITT sufficient
to equalize the interests of ITT and Rainbow Programming in MSG Holdings by
making certain scheduled payments totalling $250 million (plus interest on any
unpaid portion thereof) on specified dates up to and including March 17, 1997.
Rainbow Programming may acquire all or part of such interests in MSG Holdings
through (i) the payment of cash to ITT, (ii) the delivery to ITT, at the
option of the Company, of common or preferred stock of the Company (together
with the commitment of a nationally recognized underwriter to promptly
purchase such common or preferred stock for cash), or a combination of cash
and common or preferred stock (with such a commitment), or (iii) the delivery
to ITT, at the option of ITT, subject to certain conditions and in lieu of
payment of a limited amount of the required cash or common or preferred stock
for the purchase of a portion of such interests, of certain designated
programming interests of Rainbow Programming. If any scheduled payment is not
made on the applicable due date, then Rainbow Programming will forfeit (a) its
right to equalize the interests in MSG Holdings and (b) certain minority
rights. The Company and Rainbow Programming may fund the interest payments on
the unpaid portion of the $250 million amount required to equalize the
interests of ITT and Rainbow Programming in MSG Holdings from available cash
balances or from funds available from the Credit Agreement. Accordingly, the
Company funded an approximately $29 million interest payment on March 11, 1996
from funds available under the Credit Agreement. If certain conditions are met
and Rainbow Programming has forfeited its right to equalize the interests in
MSG Holdings, then Rainbow Programming will also have the right to require ITT
to purchase all of Rainbow Programming's interest in MSG Holdings for an
amount equal to (i) the price paid by Rainbow Programming for such interest
plus (ii) all interest paid by Rainbow Programming on the unpaid portion of
the $250 million of scheduled payments (as described above).
 
  Initially MSG Holdings will be managed on a 50-50 basis by Rainbow
Programming and ITT. If, as discussed above, Rainbow Programming does not
equalize the interests in MSG Holdings, its management role will be
effectively eliminated. Rainbow Programming also has the right to voluntarily
relinquish any power to direct the management and policies of MSG Holdings. In
connection with obtaining the consent of the National Hockey League (the
"NHL") and the National Basketball Association (the "NBA") to the indirect
transfers of the New York Rangers and the New York Knickerbockers,
respectively, resulting from the merger, the Company and Rainbow Programming
entered into agreements with the NHL and the NBA agreeing, among other
matters, to conduct themselves in accordance with the relevant rules of each
league.
 
ADVERTISING SERVICES
 
  Rainbow Advertising sells advertising time to national, regional and local
advertisers on behalf of the Company's cable television systems and the
SportsChannel and Rainbow News 12 Company programming services, as well as on
behalf of unaffiliated cable television systems.

                                USE OF PROCEEDS
 
  The Company will not receive any cash proceeds from the issuance of the New
Depositary Shares offered hereby. In consideration for issuing the New
Depositary Shares as contemplated in this Prospectus, the Company will receive
in exchange a like number of shares of Old Depositary Shares with a like
aggregate liquidation preference, the terms of which are identical in all
material respects to the New Depositary Shares. The Old Depositary Shares
surrendered in exchange for the New Depositary Shares will be retired and
cancelled and cannot be reissued. Accordingly, issuance of the New Depositary
Shares will not result in any change in capitalization of the Company.
 
  The net proceeds received by the Company from the offering of the Old
Depositary Shares were $625.0 million. The Company applied approximately $570.0
million to make a capital contribution to V Cable. Such proceeds were used to
repay approximately $500.0 million of indebtedness of V Cable and VC Holding,
Inc. and to make a capital contribution of approximately $70.0 million to U.S.
Cable. The Company applied the balance of approximately $55.0 million to repay
borrowings under the Company's principal bank credit agreement (the "Credit
Agreement"). The Company expects to reborrow the amount repaid under the Credit
Agreement in the future for general corporate purposes. See "Management's
Discussion and Analysis--Liquidity and Capital Resources" for information
concerning the Company's significant expected expenditures.

                               THE EXCHANGE OFFER
 
GENERAL
 
  In connection with the sale of the Old Depositary Shares, the purchasers
thereof became entitled to the benefits of certain registration rights (the
"Registration Rights"). Pursuant to the agreement governing the Registration
Rights (the "Registration Rights Agreement"), the Company agreed (x) within 60
days after February 15, 1996 to file a registration statement (the "Exchange
Offer Registration Statement") with the Securities and Exchange Commission (the
"Commission") with respect to a registered offer to exchange the Old Depositary
Shares for the New Depositary Shares, which will have terms identical to the
Old Depositary Shares (except that the New Depositary Shares will not contain
terms with respect to transfer restrictions) and (y) to use its best efforts to
cause the Exchange Offer Registration Statement to become effective within 180
days after February 15, 1996. Upon the Exchange Offer Registration Statement
being declared effective, the Company will offer the New Depositary Shares in
exchange for surrender of the Old Depositary Shares. The Company will keep the
Exchange Offer open for not less than 30 days (or longer if required by
applicable law) after the date notice of the Exchange Offer is mailed to the
holders of the Old Depositary Shares. For each Old Depositary Share surrendered
to the Company pursuant to the Exchange Offer, the holder of such Old
Depositary Share will receive a New Depositary Share representing Series M
Preferred Stock having a liquidation preference equal to that of the Series L
Preferred Stock represented by the surrendered Old Depositary Share.
 
  Under existing interpretations of the staff of the Commission, the New
Depositary Shares would in general be freely transferable after the Exchange
Offer without further registration under the Securities Act by holders thereof
(other than a "Restricted Holder," being (i) a broker-dealer who purchases such
New Depositary Shares directly from the Company to resell pursuant to Rule 144A
or any other available exemption under the Securities Act or (ii) a person that
is an affiliate of the Company within the meaning of Rule 405 under the
Securities Act), without compliance with the registration and prospectus
delivery provisions of the Securities Act provided that such New Depositary
Shares are acquired in the ordinary course of such holders' business and such
holders have no arrangements with any person to participate in the distribution
of such New Depositary Shares. Eligible holders wishing to accept the Exchange
Offer must represent to the Company that such conditions have been met. Each
broker-dealer that receives New Depositary Shares for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Depositary Shares.
 
  In the event that applicable interpretations of the staff of the Commission
would not permit the Company to effect the Exchange Offer or, if for any other
reason the Exchange Offer was not consummated within 240 days of the issuance
of the Old Depositary Shares, the Company agreed to use its best efforts to
cause to become effective a shelf registration statement (the "Shelf
Registration Statement") with respect to the resale of the Old Depositary
Shares and to keep the Shelf Registration Statement effective until three years
after the date of issuance of the Old Depositary Shares or such shorter period
to terminate once all the Old Depositary Shares covered by the Shelf
Registration Settlement have been sold pursuant to such Shelf Registration
Statement.
 
  Each holder of Old Depositary Shares who wishes to exchange Old Depositary
Shares for New Depositary Shares in the Exchange Offer will be required to make
certain representations, including that (i) it is neither an affiliate of the
Company nor a broker-dealer tendering Old Depositary Shares acquired directly
from the Company for its own account, (ii) any New Depositary Shares to be
received by it were acquired in the ordinary course of its business and (iii)
at the time of commencement of the Exchange Offer, it has no arrangement with
any person to participate in the distribution (within the meaning of the
Securities Act) of the New Depositary Shares. In addition, in connection with
any resales of New Depositary Shares, any broker-dealer (a "Participating
Broker-Dealer") who acquired Old Depositary Shares for its own account as a
result of market-making activities or other trading activities must deliver a
prospectus meeting the requirements of the Securities Act. The Commission has
taken the position that Participating Broker-Dealers may fulfill their
prospectus delivery requirements with respect to the New Depositary Shares
(other than a resale of an unsold allotment from the original sale of Old
Depositary Shares) with the prospectus contained
 
                                       27
<PAGE>
 
in the Exchange Offer Registration Statement. Under the Registration Rights
Agreement, the Company is required to allow Participating Broker-Dealers and
other persons, if any, subject to similar prospectus delivery requirements to
use the prospectus contained in the Exchange Offer Registration Statement in
connection with the resale of such New Depositary Shares. The Company also
agreed that in the event that either (i) the Exchange Offer Registration
Statement was not filed with the Commission on or prior to the 60th calendar
day following the date of original issue of the Old Depositary Shares, or (ii)
the Exchange Offer was not consummated or a Shelf Registration Statement was
not declared effective on or prior to the 240th calendar day following the date
of original issue of the Old Depositary Shares, the dividend rate borne by the
Series L Preferred Stock would be increased by one-quarter of one percent per
annum for the first 30 days following such 60-day period in the case of (i)
above or the first 90 days following such 240-day period in the case of (ii)
above. Such dividend rate would increase by an additional one-quarter of one
percent per annum at the beginning of each subsequent 30-day period in the case
(i) above, or 90-day period in the case of (ii) above, up to a maximum
aggregate increase of one percent per annum. The Company agreed that upon (x)
the filing of the Exchange Offer Registration Statement or (y) the consummation
of the Exchange Offer or the effectiveness of the Shelf Registration Statement,
as the case may be, the dividend rate borne by the Series L Preferred Stock
would be reduced to the original dividend rate. The Exchange Offer Registration
Statement was filed within 60 days of the date of original issue of the Old
Depositary Shares, and thus no increase in the dividend rate borne by the
Series L Preferred Stock has been made under (i) above.
 
  In the event an exchange offer is consummated, the Company will not be
required under the Registration Rights Agreement to file a Shelf Registration
Statement to register any outstanding Old Depositary Shares, and the dividend
rate on the Series L Preferred Stock will remain at its initial level of 11
1/8%. The Exchange Offer shall be deemed to have been consummated upon the
earlier to occur of (i) the Company having exchanged New Depositary Shares for
all outstanding Old Depositary Shares (other than Old Depositary Shares held by
a Restricted Holder) pursuant to the Exchange Offer and (ii) the Company having
exchanged, pursuant to the Exchange Offer, New Depositary Shares for all Old
Depositary Shares that have been tendered and not withdrawn on the date that is
30 days following the commencement of such Exchange Offer. In such event,
holders of Old Depositary Shares seeking liquidity in their investment would
have to rely on exemptions to registration requirements under the securities
laws, including the Securities Act.
 
  Upon the terms and subject to the conditions set forth in this Prospectus and
in the accompanying Letter of Transmittal, the Company will accept all Old
Depositary Shares properly tendered prior to 5:00 p.m., New York City time, on
the Expiration Date. The Company will issue one New Depositary Share
representing Series M Preferred Stock with a liquidation preference of $100 in
exchange for each issued and outstanding Old Depositary Share representing
Series L Preferred Stock with a liquidation preference of $100 accepted in the
Exchange Offer.
 
  Based on no-action letters issued by the staff of the Commission to third
parties, the Company believes that the New Depositary Shares issued pursuant to
the Exchange Offer in exchange for Old Depositary Shares may be offered for
resale, resold and otherwise transferred by holders thereof (other than any
such holder that is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act) without compliance with the registration and
prospectus delivery requirements of the Securities Act provided that such New
Depositary Shares are acquired in the ordinary course of such holders' business
and such holders have no arrangement with any person to participate in the
distribution of such New Depositary Shares. Any holder of Old Depositary Shares
who tenders in the Exchange Offer for the purpose of participating in a
distribution of the New Depositary Shares could not rely on such interpretation
by the staff of the Commission and must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction. Each broker-dealer that receives New Depositary Shares for
its own account in exchange for Old Depositary Shares, where such Old
Depositary Shares were acquired by such broker-dealer as a result of market-
making activities or other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such New Depositary
Shares. See "Plan of Distribution".
 
                                       28
<PAGE>
 
  As of the date of this Prospectus, 6,592,379 Old Depositary Shares
representing Series L Preferred Stock with an aggregate liquidation preference
of $659,237,900 are issued and outstanding. In connection with the issuance of
the Old Depositary Shares, the Company arranged for the Old Depositary Shares
to be eligible for trading in the Private Offering, Resale and Trading through
Automated Linkages (PORTAL) Market, the National Association of Securities
Dealers' screen based, automated market trading of securities eligible for
resale under Rule 144A.
 
  This Prospectus, together with the accompanying letter of transmittal (the
"Letter of Transmittal"), is being sent to all registered holders as of       ,
1996 (the "Record Date").
 
  The Company shall be deemed to have accepted validly tendered Old Depositary
Shares when, as and if the Company has given oral or written notice thereof to
The First National Bank of Boston (the "Exchange Agent"). See "Exchange Agent".
The Exchange Agent will act as agent for the tendering holders of Old
Depositary Shares for the purpose of receiving New Depositary Shares from the
Company and delivering Depositary Receipts evidencing New Depositary Shares to
such holders.
 
  If any tendered Old Depositary Shares are not accepted for exchange because
of an invalid tender or the occurrence of certain other events set forth
herein, Depositary Receipts evidencing any such unaccepted Old Depositary
Shares will be returned, without expense, to the tendering holder thereof as
promptly as practicable after the Expiration Date.
 
  Holders of Old Depositary Shares who tender 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
Old Depositary Shares pursuant to the Exchange Offer. The Company will pay all
such charges and expenses, other than certain applicable taxes, in connection
with the Exchange Offer. See "Fees and Expenses".
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" shall mean       , 1996 unless the Company, in its
sole discretion, extends the Exchange Offer to a date not later than       ,
1996, in which case the term "Expiration Date" shall mean the latest date to
which the Exchange Offer is extended. The maximum period that the Exchange
Offer will remain in effect shall be from the date of this Prospectus until the
Expiration Date.
 
  In order to extend the Expiration Date, the Company will notify the Exchange
Agent of any extension by oral or written notice and will mail to the record
holders of Old Depositary Shares 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. Such announcement may state that the Company is
extending the Exchange Offer for a specified period of time.
 
  The Company reserves the right (i) to delay acceptance of any Old Depositary
Shares, to extend the Exchange Offer or to terminate the Exchange Offer and to
refuse to accept Old Depositary Shares not previously accepted, if any of the
conditions set forth herein under "Termination" shall have occurred and shall
not have been waived by the Company (if permitted to be waived by the Company),
by giving oral or written notice of such delay, extension or termination to the
Exchange Agent, and (ii) to amend the terms of the Exchange Offer in any manner
deemed by it to be advantageous to the holders of the Old Depositary Shares.
Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof. If the
Exchange Offer is amended in a manner determined by the Company to constitute a
material change, the Company will promptly disclose such amendment in a manner
reasonably calculated to inform the holders of the Old Depositary Shares of
such amendment.
 
  Without limiting the manner in which the Company may choose to make public
announcements of any delay in acceptance, extension, termination or amendment
of the Exchange Offer, the Company shall have no obligation to publish,
advertise, or otherwise communicate any such public announcement, other than by
making a timely release to the Dow Jones News Service.
 
                                       29

DIVIDENDS ON THE SERIES M PREFERRED STOCK
 
  Dividends on the Series M Preferred Stock will accumulate from the most
recent dividend payment date to which dividends on the Series L Preferred Stock
were paid (the "Accrual Date") and are payable quarterly in arrears on January
1, April 1, July 1 and October 1, of each year commencing on July 1, 1996, at
the rate of 11 1/8% per annum out of legally available funds. Holders of Old
Depositary Shares whose Old Depositary Shares are accepted for exchange will be
deemed to have waived the right to receive any payment in respect of dividends
on the Series L Preferred Stock accumulated from the Accrual Date until the
date of the issuance of the New Depositary Shares. Consequently, holders who
exchange their Old Depositary Shares for New Depositary Shares will receive the
same dividend payment on the next dividend payment date (expected to be July 1,
1996) that they would have received had they not accepted the Exchange Offer,
except that if such dividend is not paid in cash, it will be paid in shares of
New Depositary Shares instead of Old Depositary Shares.
 
PROCEDURES FOR TENDERING
 
  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
Depositary Receipts evidencing Old Depositary Shares and any other required
documents, to the Exchange Agent prior to 5:00 p.m., New York City time, on the
Expiration Date.
 
  The tender by a holder of Old Depositary Shares will constitute an agreement
between such holder and the Company in accordance with the terms and subject to
the conditions set forth herein and in the Letter of Transmittal.
 
  Delivery of all documents must be made to the Exchange Agent at its address
set forth herein. Holders may also request that their respective brokers,
dealers, commercial banks, trust companies or nominees effect such tender for
such holders.
 
  The method of delivery of Depositary Receipts evidencing Old Depositary
Shares and the Letter of Transmittal and all other required documents to the
Exchange Agent is at the election and risk of the holders. Instead of delivery
by mail, it is recommended that holders use an overnight or hand delivery
service. In all cases, sufficient time should be allowed to assure timely
delivery. No Letter of Transmittal or Depositary Receipts evidencing Old
Depositary Shares should be sent to the Company.
 
  Only a holder of Old Depositary Shares may tender such Old Depositary Shares
in the Exchange Offer. The term "holder" with respect to the Exchange Offer
means any person in whose name the Old Depositary Shares are registered on the
books of the Company or any other person who has obtained a properly completed
stock power from the registered holder.
 
  Holders of Old Depositary Shares who wish to tender additional Old Depositary
Shares received on April 1, 1996 as a dividend payment with respect to the
Series L Preferred Stock may do so.
 
  Any beneficial holder whose Old Depositary Shares are registered in the name
of his 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 his behalf. If such beneficial holder
wishes to tender on his own behalf, such beneficial holder must, prior to
completing and executing the Letter of Transmittal and delivering his
Depositary Receipts evidencing Old Depositary Shares, either make appropriate
arrangements to register ownership of the Old Depositary Shares in such
holder's name or obtain a properly completed stock power from the registered
holder. The transfer of record ownership may take considerable time.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by a member firm of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution") unless the Old
Depositary Shares tendered pursuant thereto are tendered (i) by a registered
holder who has not completed the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution.
 
                                       30
<PAGE>
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Old Depositary Shares listed therein, the Depositary Receipts
evidencing such Old Depositary Shares must be endorsed or accompanied by
appropriate stock powers which authorize such person to tender the Old
Depositary Shares on behalf of the registered holder, in either case signed as
the name of the registered holder or holders appears on the Depositary Receipts
evidencing Old Depositary Shares.
 
  If the Letter of Transmittal or any Depositary Receipts evidencing Old
Depositary Shares or stock 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 Company, evidence satisfactory
to the Company of their authority to so act must be submitted with the Letter
of Transmittal.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of the tendered Old Depositary Shares will
be determined by the Company in its sole discretion, which determination will
be final and binding. The Company reserves the absolute right to reject any and
all Old Depositary Shares not properly tendered or any Old Depositary Shares
the Company's acceptance of which would, in the opinion of counsel for the
Company, be unlawful. The Company also reserves the absolute right to waive any
irregularities or conditions of tender as to particular Old Depositary Shares.
The Company's 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 Old Depositary Shares must be cured within such time
as the Company shall determine. Neither the Company, the Exchange Agent nor any
other person shall be under any duty to give notification of defects or
irregularities with respect to tenders of Old Depositary Shares nor shall any
of them incur any liability for failure to give such notification. Tenders of
Old Depositary Shares will not be deemed to have been made until such
irregularities have been cured or waived. Any Depositary Receipts evidencing
Old Depositary Shares 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 without cost by the Exchange Agent to the tendering
holder of such Old Depositary Shares unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
  In addition, the Company reserves the right in its sole discretion to (a)
purchase or make offers for any Old Depositary Shares that remain outstanding
subsequent to the Expiration Date, or, as set forth under "Termination", to
terminate the Exchange Offer and (b) to the extent permitted by applicable law,
purchase Old Depositary Shares in the open market, in privately negotiated
transactions or otherwise. The terms of any such purchases or offers may differ
from the terms of the Exchange Offer.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Old Depositary Shares and (i) whose Old
Depositary Shares are not immediately available, or (ii) who cannot deliver
their Depositary Receipts evidencing Old Depositary Shares, the Letter of
Transmittal or any other required documents to the Exchange Agent prior to the
Expiration Date, or (iii) who cannot complete the procedure for book-entry
transfer on a timely basis, 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 of the Old Depositary
  Shares, the number or numbers of Depositary Receipts evidencing such Old
  Depositary Shares and the number of Old Depositary Shares tendered, stating
  that the tender is being made thereby, and guaranteeing that, within five
  business days after the Expiration Date, the Letter of Transmittal (or
  facsimile thereof), together with the Depositary Receipts evidencing the
  Old Depositary Shares to be tendered in proper form for transfer and any
  other documents required by the Letter of Transmittal, will be deposited by
  the Eligible Institution with the Exchange Agent; and
 
                                       31
<PAGE>
 
    (c) Such properly completed and executed Letter of Transmittal (or
  facsimile thereof), together with Depositary Receipts evidencing all
  tendered Old Depositary Shares in proper form for transfer and all other
  documents required by the Letter of Transmittal are received by the
  Exchange Agent within five business days after the Expiration Date.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Old Depositary Shares may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the business
day prior to the Expiration Date, unless previously accepted for exchange.
 
  To withdraw a tender of Old Depositary Shares in the Exchange Offer, a
written or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at its address set forth herein prior to 5:00 p.m., New York
City time, on the business day prior to the Expiration Date and prior to
acceptance for exchange thereof by the Company. Any such notice of withdrawal
must (i) specify the name of the person having deposited the Old Depositary
Shares to be withdrawn (the "Depositor"), (ii) identify the Old Depositary
Shares to be withdrawn (including the Depositary Receipt number or numbers and
number of Old Depositary Shares), (iii) be signed by the Depositor in the same
manner as the original signature on the Letter of Transmittal by which such Old
Depositary Shares were tendered (including any required signature guarantees)
or be accompanied by documents of transfer sufficient to permit the Trustee
with respect to the Old Depositary Shares to register the transfer of such Old
Depositary Shares into the name of the Depositor withdrawing the tender, and
(iv) specify the name in which any such Old Depositary Shares 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 withdrawal
notices will be determined by the Company, whose determination shall be final
and binding on all parties. Any Old Depositary Shares so withdrawn will be
deemed not to have been validly tendered for purposes of the Exchange Offer and
no New Depositary Shares will be issued with respect thereto unless the Old
Depositary Shares so withdrawn are validly retendered. Any Old Depositary
Shares 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 Old Depositary Shares may be retendered by
following one of the procedures described above under "Procedures for
Tendering" at any time prior to the Expiration Date.
 
TERMINATION
 
  Notwithstanding any other term of the Exchange Offer, the Company will not be
required to accept for exchange, or exchange New Depositary Shares for, any Old
Depositary Shares not theretofore accepted for exchange, and may terminate or
amend the Exchange Offer as provided herein before the acceptance of such Old
Depositary Shares if: (i) 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 Company's judgment, might materially impair the
Company's ability to proceed with the Exchange Offer, (ii) any law, statute,
rule or regulation is proposed, adopted or enacted, or any existing law,
statute, rule or regulation is interpreted by the staff of the Commission in a
manner, which, in the Company's judgment, might materially impair the Company's
ability to proceed with the Exchange Offer, or (iii) the Company reasonably
deems it advisable to terminate the Exchange Offer.
 
  If the Company determines that it may terminate the Exchange Offer, as set
forth above, the Company may (i) refuse to accept any Old Depositary Shares and
return any Depositary Receipts evidencing Old Depositary Shares that have been
tendered to the holders thereof, (ii) extend the Exchange Offer and retain all
Old Depositary Shares tendered prior to the Expiration of the Exchange Offer,
subject to the rights of such holders of tendered Old Depositary Shares to
withdraw their tendered Old Depositary Shares, (iii) waive such termination
event with respect to the Exchange Offer and accept all properly tendered Old
Depositary Shares that have not been withdrawn. If such waiver constitutes a
material change in the Exchange Offer, the Company will disclose such change by
means of a supplement to this Prospectus that will be distributed to each
registered holder of Old Depositary Shares, and the Company will extend the
Exchange Offer for a period of five to ten business days, depending upon the
significance of the waiver and the manner of disclosure
 
                                       32
<PAGE>
 
to the registered holders of the Old Depositary Shares, if the Exchange Offer
would otherwise expire during such period. See "Description of New Depositary
Shares, Series M Preferred Stock and Exchange Debentures--Registration Rights
Agreement".
 
EXCHANGE AGENT
 
  The First National Bank of Boston has been appointed as Exchange Agent for
the Exchange Offer.
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by the Company. The principal solicitation for tenders pursuant to the
Exchange Offer is being made by mail. Additional solicitations may be made by
officers and regular employees of the Company and its affiliates in person, by
telegraph or telephone.
 
  The Company will not make any payments to brokers, dealers or other persons
soliciting acceptances of the Exchange Offer. The Company, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse the Exchange Agent for its reasonable out-of-pocket expenses in
connection therewith. The Company may also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus, Letters of
Transmittal and related documents to the beneficial owners of the Old
Depositary Shares and in handling or forwarding tenders for exchange.
 
  The expenses to be incurred by the Company and the Exchange Agent in
connection with the Exchange Offer, including the fees of the Exchange Agent
and accounting and legal fees, will be paid by the Company.
 
  The Company will pay all transfer taxes, if any, applicable to the exchange
of Old Depositary Shares pursuant to the Exchange Offer. If, however,
Depositary Receipts evidencing New Depositary Shares or Old Depositary Shares
not tendered or accepted for exchange are to be delivered to, or are to be
registered or issued in the name of, any person other than the registered
holder of the Old Depositary Shares tendered, or if tendered Old Depositary
Shares are registered in the name of any person other than the person signing
the Letter of Transmittal, or if a transfer tax is imposed for any reason other
than the exchange of Old Depositary Shares pursuant to the Exchange Offer, then
the amount of any such transfer taxes (whether imposed on the registered holder
or any other persons) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted with
the Letter of Transmittal, the amount of such transfer taxes will be billed
directly to such tendering holder.
 
ACCOUNTING TREATMENT
 
  No gain or loss for accounting purposes will be recognized by the Company
upon the consummation of the Exchange Offer as the expenses of the Exchange
Offer will be charged to paid-in capital.

FOOTNOTES:
 
(1) See "Management's Discussion and Analysis--Liquidity and Capital Resources"
    and the Consolidated Financial Statements for a description of the bank
    indebtedness. This indebtedness consists of the Company's indebtedness
    under its principal bank credit agreement, the New Jersey subsidiary credit
    agreement and the Cablevision of NYC credit agreement. These amounts do not
    include approximately $20.4 million reserved under the Company's bank
    credit agreements for certain letters of credit issued on behalf of the
    Company. The Company and its New Jersey subsidiary are jointly and
    severally liable under the New Jersey subsidiary credit agreement.
(2) Obligation of NYC LP Corp., a wholly-owned Unrestricted Group subsidiary,
    relating to the acquisition of Cablevision of NYC, which obligation has
    been guaranteed by the Company. NYC LP Corp.'s obligation under such
    guarantee may be paid in cash or, at the Company's option, shares of the
    Company's Common Stock. Under the Credit Agreement, the Company is
    currently prohibited from paying all but $40.0 million of this obligation
    in cash and, accordingly, without the consent of the Company's bank
    lenders, would be required to pay it in shares of the Company's Common
    Stock.

                          DESCRIPTION OF CAPITAL STOCK
 
  The Company is authorized to issue 80,000,000 shares of capital stock, of
which 50,000,000 shares are Class A Common Stock, par value $.01 per share,
20,000,000 shares are Class B Common Stock, par value $.01 per share, and
10,000,000 shares are preferred stock, par value $.01 per share, of which the
Preferred Stock offered hereby will be a series.
 
CLASS A COMMON STOCK AND CLASS B COMMON STOCK
 
  Voting. Holders of Class A Common Stock are entitled to one vote per share.
Holders of Class B Common Stock are entitled to ten votes per share. All
actions submitted to a vote of stockholders are voted on by holders of Class A
Common Stock and Class B Common Stock voting together as a single class, except
for the election of directors and as otherwise set forth below. With respect to
the election of directors, holders of Class A Common Stock vote as a separate
class and are entitled to elect 25% of the total number of directors
constituting the whole Board of Directors (the "Class A Directors") and, if
such 25% is not a whole number, then the holders of Class A Common Stock are
entitled to elect the nearest higher whole number of directors that is at least
25% of the total number of directors. Holders of Class B Common Stock, voting
as a separate class, are entitled to elect the remaining directors. If,
however, on the record date for any stockholder meeting at which directors are
to be elected, the number of outstanding shares of Class A Common Stock is less
than 10% of the total number of outstanding shares of both classes of Common
Stock, the holders of Class A Common Stock and Class B Common Stock will vote
together as a single class with respect to the election of directors and the
holders of Class A Common Stock will not have the right to elect 25% of the
total number of directors but will have one vote per share for all directors
and holders of Class B Common Stock will have ten votes per share for all
directors. If, on the record date for any stockholder meeting at which
directors are to be elected, the number of outstanding shares of Class B Common
Stock is less than 12 1/2% of the total number of outstanding shares of both
classes of Common Stock, then the holders of Class A Common Stock, voting as a
separate class, would continue to elect a number of Class A Directors equal to
25% of the total number of directors constituting the whole Board of Directors
and, in addition, would vote together with the holders of Class B Common Stock
to elect the remaining directors to be elected at such meeting, with the
holders of Class A Common Stock entitled to one vote per share and the holders
of Class B Common Stock entitled to ten votes per share.
 
  In addition, the affirmative vote or consent of the holders of at least 66
2/3% of the outstanding shares of Class B Common Stock, voting separately as a
class, is required for the authorization or issuance of any additional shares
of Class B Common Stock and for any amendment, alteration or repeal of any
provisions of the Company's Certificate of Incorporation which would affect
adversely the powers, preferences or rights of the Class B Common Stock. The
Company's Certificate of Incorporation does not provide for cumulative voting.
 
  Conversion. The Class A Common Stock has no conversion rights. The Class B
Common Stock is convertible into Class A Common Stock in whole or in part at
any time and from time to time on the basis of one share of Class A Common
Stock for each share of Class B Common Stock.
 
  Dividends. Holders of Class A Common Stock and Class B Common Stock are
entitled to receive dividends equally on a per share basis if and when such
dividends are declared by the Board of Directors from funds legally available
therefor. No dividend may be declared or paid in cash or property on shares of
either Class A Common Stock or Class B Common Stock unless the same dividend is
paid simultaneously on each share of the other class of common stock. In the
case of any stock dividend, holders of Class A Common Stock are entitled to
receive the same percentage dividend (payable in shares of Class A Common
Stock) as holders of Class B Common Stock receive (payable in shares of Class B
Common Stock). The Company's Certificate of Incorporation provides that the
distribution of shares of capital stock of any subsidiary to common
stockholders may differ to the extent that the common stock differs as to
voting rights and rights in connection with certain dividends.
 
                                       36
<PAGE>
 
  Liquidation. Holders of Class A Common Stock and Class B Common Stock share
with each other on a ratable basis as a single class in the net assets
available for distribution in respect of Class A Common Stock and Class B
Common Stock in the event of liquidation.
 
  Other Terms. Neither the Class A Common Stock nor the Class B Common Stock
may be subdivided, consolidated, reclassified or otherwise changed unless
contemporaneously therewith the other class of shares is subdivided,
consolidated, reclassified or otherwise changed in the same proportion and in
the same manner. In any merger, consolidation or business combination the
consideration to be received per share by holders of either Class A Common
Stock or Class B Common Stock must be identical to that received by holders of
the other class of Common Stock, except that in any such transaction in which
shares of capital stock are distributed, such shares may differ as to voting
rights only to the extent that voting rights now differ between Class A Common
Stock and Class B Common Stock.
 
  Restrictions on Ownership. Transfer of shares of Class A Common Stock or
Class B Common Stock which could result in a change of control of the Company
may require the approval of state agencies or local franchising authorities in
certain states in which the Company operates.
 
  Transfer Agent. The Company's transfer agent and registrar for the Class A
Common Stock is Mellon Securities Trust Company.
 
  No Preemptive Rights. The shares of common stock have no preemptive or other
rights to subscribe for or purchase any proportionate part of any new or
additional issues of stock of any class or of securities convertible into stock
of any class.
 
PREFERRED STOCK
 
  The following description of the terms of the Company's preferred stock sets
forth certain general terms and provisions of the preferred stock. The
description set forth below is subject to and qualified in its entirety by
reference to the certificate of designations establishing a particular series
of preferred stock.
 
  General. Under the Certificate of Incorporation, the Board of Directors of
the Company is authorized, without further stockholder action, to provide for
the issuance of up to 10,000,000 shares of preferred stock in one or more
series. Subject to limitations imposed by law or the Company's Certificate of
Incorporation, the Board of Directors is empowered to determine (a) the maximum
number of shares to constitute the series and the distinctive designation
thereof; (b) whether the shares of such series shall have voting rights, in
addition to any voting rights provided by law, and, if so, the terms of such
voting rights; (c) the dividend rate, if any, on the shares of such series, the
conditions and dates upon which such dividends shall be payable, the preference
or relation which such dividends shall bear to the dividends payable on any
other class or classes or on any other series of capital stock, and whether
such dividends shall be cumulative or non-cumulative; (d) whether the shares of
such series shall be subject to redemption by the Company, and, if made subject
to redemption, the times, prices and other terms and conditions of such
redemption; (e) the rights of the holders of shares of such series upon the
liquidation, dissolution or winding up of the Company; (f) whether or not the
shares of such series shall be subject to the operation of a retirement or
sinking fund, and, if so, the extent to and manner in which any such retirement
or sinking fund shall be applied to the purchase or redemption of the shares of
such series for retirement or to other corporate purposes and the terms and
provisions relative to the operation thereof; (g) whether or not the shares of
such series shall be convertible into, or exchangeable for, shares of stock of
any other class or classes, or of any other series of the same class, and if so
convertible or exchangeable, the price or prices or the rate or rates of
conversion or exchange and the method, if any, of adjusting the same; (h) the
limitations and restrictions, if any, to be effective while any shares of such
series are outstanding upon the payment of dividends or making of other
distributions on, and upon the purchase, redemption or other acquisition by the
Company of, the Class A Common Stock, the Class B Common Stock or any other
class or classes of stock of the Company ranking junior to the shares of such
series either as to dividends or upon liquidation; (i) the conditions or
restrictions,
 
                                       37
<PAGE>
 
if any, upon the creation or indebtedness of the Company or upon the issue or
any additional stock (including additional shares of such series or of any
other series or of any other class) ranking on a parity with or prior to the
shares of such series as to dividends or distribution of assets on liquidation,
dissolution or winding up; (j) whether fractional interests in shares of the
series will be offered in the form of Depositary Shares; and (k) any other
preference and relative, participating, optional or other special rights or
qualifications, limitations or restrictions thereof.
 
 Designated Preferred Stock.
 
  General. The authorized preferred stock of the Company consists of (i)
200,000 shares of Series B Cumulative Preferred Stock, $.01 par value and $100
liquidation value per share (the "Series B Preferred Stock"), none of which are
outstanding, (ii) 112,500 shares of 8% Series C Cumulative Preferred Stock,
$.01 par value and $100 liquidation value per share (the "Series C Preferred
Stock"), of which 110,622 shares were outstanding at December 31, 1995, (iii)
112,500 shares of 8% Series D Cumulative Preferred Stock, $.01 par value and
$100 liquidation value per share, none of which are outstanding (the "Series D
Preferred Stock"), (iv) 100,000 shares of Series E Redeemable Exchangeable
Convertible Preferred Stock, $.01 par value and $1,000 liquidation preference
per share, none of which are outstanding (the "Series E Preferred Stock"), (v)
100,000 shares of Series F Redeemable Preferred Stock, $.01 par value and
$1,000 liquidation preference per share, none of which are outstanding (the
"Series F Preferred Stock"), (vi) 4,500,000 shares of Series G Preferred Stock,
2,500,000 shares of which were issued on September 26, 1995 and are
outstanding, 77,510 shares of which were issued on January 2, 1996 and are
outstanding and 75,857 shares of which were issued on April 1, 1996 and are
outstanding, (viii) 1,380,000 shares of 8 1/2% Series I Cumulative Convertible
Exchangeable Preferred Stock (the "Series I Preferred Stock"), 1,380,000 shares
of which are outstanding and represented by 13,800,000 depositary shares, and
(ix) 115,000 shares of 11 1/8% Series L Redeemable Exchangeable Preferred Stock
(the "Series L Preferred Stock"), 65,000 shares of which were issued on
February 15, 1996 and are outstanding and are represented by 6,500,000
depositary shares and 923.79 shares of which were issued on April 1, 1996 and
are outstanding and are represented by 92,379 depositary shares (the Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
Preferred Stock, Series F Preferred Stock, Series G Preferred Stock, Series I
Preferred Stock and the Series L Preferred Stock are hereinafter sometimes
collectively referred to as the "Authorized Preferred Stock"). The Series A
Preferred Stock, $.01 par value, was cancelled by the Board of Directors on
February 2, 1988. The Company does not expect to issue any Series B Preferred
Stock. The Series D Preferred Stock is issuable upon conversion of the Series C
Preferred Stock. The Company redeemed the Series E Preferred Stock on November
2, 1995. The Series F Preferred Stock would have been issuable upon conversion
of the Series E Preferred Stock. The Company anticipates that it will, prior to
the consummation of the Exchange Offer, file a certificate of cancellation with
respect to all of the authorized shares of Series E Preferred Stock and Series
F Preferred Stock with the Delaware Secretary of State. The right to dividends
on shares of the Authorized Preferred Stock are cumulative.
 
  Series B, Series C and Series D Preferred Stock. The holders of such Series B
Preferred Stock are entitled, when declared by the Board of Directors, to
dividends at the time legally available at the annual rate of $12.00 per share
prior and in preference to any declaration of payment of any dividend on the
common stock of the Company. The holders of Series C Preferred Stock and Series
D Preferred Stock are entitled, when declared by the Board of Directors, to
dividends out of legally available funds at the annual rate of $8.00 per share
prior and in preference to any declaration of payment of any dividend on the
common stock of the Company.
 
  At any time and from time to time commencing on December 31, 1997, the
holders of Series C Preferred Stock and Series D Preferred Stock may require
the Company to redeem, upon 30 days' notice to the Company, any or all of the
shares of Series C Preferred Stock and Series D Preferred Stock then
outstanding at a price equal to the lesser of (i) $100 per share or (ii) the
present value of $100, discounted from December 31, 2007 to the date of such
redemption, plus, in each case, all dividends (whether or not earned or
declared) accrued and unpaid on the shares of Series C Preferred Stock and
Series D Preferred Stock to the date fixed for redemption (the "Series C
Preferred Stock and Series D Preferred Stock Redemption
 
                                       38
<PAGE>
 
Price"). The Company may, at its option, upon notice to the holders requesting
redemption within 20 days of such holders' notice to the Company, convert all
or part of such shares of Series C Preferred Stock into Class B Common Stock
and all or part of such shares of Series D Preferred Stock into Class A Common
Stock. The Company at its option may, but shall not be required to, redeem, at
any time and from time to time after December 31, 1997 on not less than 30
days' nor more than 60 days' prior notice, any or all of the shares of Series C
Preferred Stock and Series D Preferred Stock then outstanding at the Series C
Preferred Stock and Series D Preferred Stock Redemption Price.
 
  If the Company elects to convert any shares of Series C Preferred Stock or
Series D Preferred Stock after a demand for redemption by such holders, the
number of shares to be issued by the Company shall be calculated by dividing
the applicable Series C Preferred Stock and Series D Preferred Stock Redemption
Price by the average of the market price of a share of Class A Common Stock for
the 30 trading days preceding the date on which a holder gives notice of its
election to convert such shares. Holders of Series C Preferred Stock and Series
D Preferred Stock have no voting rights except as to which they may be entitled
under the laws of the State of Delaware.
 
  In the event of any liquidation, dissolution or winding up the Company, the
holders of Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock are entitled to receive a preferential amount equal to $100 for
each share of Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock held plus all dividends (whether or not earned or declared)
accumulated and unpaid on such shares of Authorized Preferred Stock to the date
of final distribution in preference to any such distribution to the holders of
the common stock of the Company. If, upon any voluntary or involuntary
liquidation, dissolution or winding up of the Company, the amounts payable with
respect to the Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock are not paid in full , the holders of the Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and any other
preferred stock on parity therewith will share equally and ratably in any
distribution of the assets of the Company in proportion to the full liquidation
preference to which each is entitled. Neither the sale, conveyance, exchange or
transfer (for cash, shares of stock, securities or other consideration) of all
or substantially all the property or assets of the Company nor the
consolidation or merger of the Company with one or more corporations shall be
deemed a liquidation, dissolution or winding up of the Company.
 
  Series G Preferred Stock and Series H Preferred Stock. The Series G Preferred
Stock, with respect to dividends and distributions upon the liquidation,
winding-up and dissolution of the Company, ranks (i) senior to all classes of
Common Stock and each other class of capital stock or series of preferred stock
established by the Board of Directors (except as set forth below) which does
not expressly provide that it ranks senior to the Series G Preferred Stock as
to dividends and distributions upon the liquidation, winding-up and dissolution
of the Company (collectively referred to as "Series G Junior Stock"); (ii) on a
parity with the Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, 11 3/4% Series H Redeemable Exchangeable Preferred Stock
("Series H Preferred Stock"), Series I Preferred Stock, Series L Preferred
Stock, Series M Preferred Stock and any other class of capital stock or series
of preferred stock issued by the Company established after the initial issuance
of the Series G Preferred Stock by the Board of Directors, the terms of which
expressly provide that such class or series will rank on a parity with the
Series G Preferred Stock as to dividends and distributions upon the
liquidation, winding-up and dissolution of the Company (collectively referred
to as "Series G Parity Securities"); and (iii) junior to each class of capital
stock or series of preferred stock issued by the Company established after the
initial issuance of the Series G Preferred Stock by the Board of Directors, the
terms of which specifically provide that such class or series will rank senior
to the Series G Preferred Stock as to dividends and distributions upon the
liquidation, winding-up and dissolution of the Company (collectively referred
to as "Series G Senior Securities").
 
  No full dividends may be declared or paid or funds set apart for the payment
of dividends on any Series G Parity Securities for any period unless full
cumulative dividends shall have been paid or set apart for such payment on the
Series G Preferred Stock. If full dividends are not so paid, the Series G
Preferred Stock shall
 
                                       39
<PAGE>
 
share dividends pro rata with the Series G Parity Securities. Subject to
certain exceptions set forth in the certificate of designations for the Series
G Preferred Stock, no dividends may be paid or set apart for such payment on
Series G Junior Stock (except dividends on Series G Junior Stock in additional
shares of Series G Junior Stock), and no Series G Junior Stock may be
repurchased, redeemed or otherwise retired nor may funds be set apart for
payment with respect thereto, if full dividends have not been paid on the
Series G Preferred Stock.
 
  The Company may redeem the Series G Preferred Stock at any time after October
1, 2002, in whole or in part, at certain redemption prices. In addition, the
Company may redeem shares of Series G Preferred Stock at any time before
October 1, 1998 at a redemption price per share equal to the liquidation
preference of $100, plus accumulated and unpaid dividends plus a premium of $10
per share, out of the net proceeds of the sale of Series G Junior Stock to a
Strategic Equity Investor or a public offering of Class A Common Stock.
Furthermore, the Company may, at its option, prior to October 1, 2002, redeem
the Series G Preferred Stock at any time within 180 days, at certain redemption
prices, after a Change in Control (as defined in the Certificate of
Designations for the Series G Preferred Stock). On October 1, 2007, the Company
will be required to redeem all outstanding shares of Series G Preferred Stock
out of funds legally available.
 
  The Company may, at its option, on any scheduled dividend payment date,
exchange the Series G Preferred Stock for the Company's 11 3/4% Senior
Subordinated Debentures due 2007.
 
  In the event of any liquidation, winding-up or dissolution of the Company,
holders of Series G Preferred Stock will be entitled to receive a preferential
amount equal to $100 per share, plus all accumulated and unpaid dividends
thereon to the date fixed for liquidation, dissolution or winding-up of the
Company (including an amount equal to a prorated dividend from the last
dividend payment date to the date fixed for liquidation, dissolution or
winding-up), before any distribution is made on the Series G Junior Stock. If
upon any voluntary or involuntary liquidation, dissolution or winding up of the
Company, the amounts payable with respect to the Series G Preferred Stock and
all other Series G Parity Securities are not paid in full, the holders of the
Series G Preferred Stock and the Series G Parity Securities will share equally
and ratably in any distribution of assets of the Company in proportion to the
full liquidation preference to which each is entitled. After payment of the
full amount of the liquidation preferences to which they are entitled, the
holders of shares of Series G Preferred Stock will not be entitled to any
further participation in any distribution of assets of the Company. Neither the
sale, conveyance, exchange or transfer (for cash, shares of stock, securities
or other consideration) of all or substantially all the property or assets of
the Company nor the consolidation or merger of the Company with one or more
corporations shall be deemed a liquidation, dissolution or winding up of the
Company.
 
  Holders of the Series G Preferred Stock will have no voting rights with
respect to general corporate matters except as provided by law or as set forth
in the Certificate of Designations therefor. The Certificate of Designations
for the Series G Preferred Stock provides that (a) dividends on the Series G
Preferred Stock are in arrears and unpaid (and if after October 1, 2000, such
dividends are not paid in cash) for six quarterly periods (whether or not
consecutive), or (b) the Company fails to discharge its redemption obligation
to redeem the Series G Preferred Stock on October 1, 2007, the number of
directors constituting the Board of Directors will be adjusted to permit the
holders of the majority of the then outstanding Series G Preferred Stock,
voting as a class, to elect a director. Such voting rights will continue until
such time as all dividends in arrears on the Series G Preferred Stock are paid
in full (and in the case of dividends payable after October 1, 2000, paid in
cash) and any failure, breach or default referred to in clause (b) is remedied,
at which time the term of the directors elected pursuant to the provisions of
this paragraph shall terminate. Each such event described in clauses (a) and
(b) above is referred to herein as a "Series G Voting Rights Triggering Event".
 
  The Certificate of Designations for the Series G Preferred Stock also
provides that the Company will not authorize any class of Series G Senior
Securities without the affirmative vote or consent of holders of at least a
majority of the shares of Series G Preferred Stock then outstanding, voting or
consenting, as the case may be, separately as one class. The Company may not
amend the Certificate of Designations for the Series G
 
                                       40
<PAGE>
 
Preferred Stock so as to affect adversely the specified rights, preferences,
privileges or voting rights of holders of shares of the Series G Preferred
Stock, or authorize the issuance of any additional shares of Series G Preferred
Stock, without the affirmative vote or consent of the holders of at least a
majority of the outstanding shares of Series G Preferred Stock, voting or
consenting, as the case may be, as one class.
 
  Without the affirmative vote or consent of a majority of the issued and
outstanding shares of Series G Preferred Stock, the Company may not consolidate
or merge with or into, or sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its assets to, any person unless: (a)
the entity formed by such consolidation or merger (if other than the Company)
or to which such sale, assignment, transfer, lease, conveyance or other
disposition shall have been made shall be a corporation organized and existing
under the laws of the United States or any State thereof or the District of
Columbia; (b) the Series G Preferred Stock shall be converted into or exchanged
for and shall become shares of such successor, transferee or resulting
corporation, having in respect of such successor, transferee or resulting
corporation the same powers, preferences and relative participating, optional
or special rights, and the qualifications, limitations or restrictions thereon,
that the Series G Preferred Stock had immediately prior to such transactions;
and (c) immediately after giving effect to such transaction, no Series G Voting
Rights Triggering Event shall have occurred and be continuing. Notwithstanding
the foregoing, the Company may consolidate or merge with or into, or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially
all of its assets to, any person if the Company makes adequate provision (i)
prior to October 1, 2002, to redeem the Series G Preferred Stock after a Change
in Control (as defined in the Certificate of Designations for the Series G
Preferred Stock) or (ii) on or after October 1, 2002, to redeem the Series G
Preferred Stock at the applicable redemption price set forth in the certificate
of designations therefor.
 
  The Series H Preferred Stock will have terms identical to the Series G
Preferred Stock, except that the Series H Preferred Stock will not contain
terms restricting the transfer thereof and the terms of the Series H Preferred
Stock clarify the calculation of the Make-Whole Premium applicable to an
optional redemption following a Change of Control.
 
  Series I Preferred Stock. The Series I Preferred Stock, with respect to
dividends and distributions upon the liquidation, winding-up and dissolution of
the Company, ranks (i) senior to all classes of Common Stock and each other
class of capital stock or series of preferred stock established by the Board of
Directors after the issuance of the Series I Preferred Stock which does not
expressly provide that it ranks senior to or on a parity with the Series I
Preferred Stock as to dividends and distributions upon the liquidation,
winding-up and dissolution of the Company (collectively referred to as "Series
I Junior Stock"); (ii) on a parity with the Company's Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock (which may be issued in
exchange for shares of the Series C Preferred Stock), Series G Preferred Stock,
Series H Preferred Stock, Series L Preferred Stock, Series M Preferred Stock
and any other class of capital stock or series of preferred stock established
by the Board of Directors after the initial issuance of the Series I Preferred
Stock, the terms of which expressly provide that such class or series will rank
on a parity with the Series I Preferred Stock as to dividends and distributions
upon the liquidation, winding-up and dissolution of the Company (collectively
referred to as "Series I Parity Stock"); and (iii) junior to each class of
capital stock or series of preferred stock established by the Board of
Directors after the initial issuance of the Series I Preferred Stock, the terms
of which specifically provide that such class or series will rank senior to the
Series I Preferred Stock as to dividends and distributions upon the
liquidation, winding-up and dissolution of the Company (collectively referred
to as "Series I Senior Stock").
 
  Holders of the Series I Preferred Stock are entitled, when declared by the
Board of Directors, out of funds legally available therefor, to receive
cumulative cash dividends on each outstanding share of the Series I Preferred
Stock, at the annual rate of 8 1/2% or $21.25 per share of Series I Preferred
Stock (equivalent to $2.125 per annum per depositary share). Dividends on the
Series I Preferred Stock are payable quarterly in arrears on January 1, April
1, July 1 and October 1 of each year. Dividends will be payable to the holder
of record on the respective record date as may be fixed by the Board of
Directors in advance of each dividend.
 
                                       41
<PAGE>
 
The right to dividends on the Series I Preferred Stock will be cumulative
(whether or not earned or declared) from the date of issuance of the Series I
Preferred Stock. If any dividend (or portion thereof) payable on any dividend
payment date is not paid in full on the dividend payment date therefor, the
amount of such dividend that is payable and that is not paid on such date will
increase at the rate of 8 1/2% per annum per share of Series I Preferred Stock
from such dividend payment date until paid in full.
 
  No full dividends may be declared or paid or funds set apart for the payment
of dividends on any Series I Parity Stock for any period unless full cumulative
dividends shall have been paid or set apart for such payment on the Series I
Preferred Stock. If the funds available for the payment of dividends are
insufficient to pay in full the dividends payable on all outstanding shares of
Series I Preferred Stock and any series of Series I Parity Stock, the total
available funds to be paid in partial dividends shall be divided among the
Series I Preferred Stock and such other series pro rata in proportion to the
aggregate amount of dividends accrued and unpaid with respect to such Series I
Preferred Stock and such other series. Subject to various exceptions set forth
in the certificate of designations for the Series I Preferred Stock, no
dividends may be paid or set apart for such payment on Series I Junior Stock
(except dividends on Series I Junior Stock in additional shares of Series I
Junior Stock), and no Series I Junior Stock, or any warrants, rights, calls or
options exercisable for or convertible into any Series I Junior Stock, may be
repurchased, redeemed or otherwise retired nor may funds be set apart for
payment with respect thereto, if full dividends have not been paid on the
Series I Preferred Stock. After dividends on the Series I Preferred Stock for
all past and current quarterly dividend periods have been paid in full, the
Series I Preferred Stock will not be entitled to participate in any further
distributions by the Company.
 
  On or after January 1, 1998, the Company may, at its option, on any scheduled
dividend payment date, exchange the Series I Preferred Stock, in whole but not
in part, for the Company's 8 1/2% Convertible Subordinated Debentures due 2007
(the "Series I Exchange Debentures").
  The Company at its option may redeem the Series I Preferred Stock (subject to
contractual and other restrictions with respect thereto and to the legal
availability of funds therefor) at any time after November 1, 1999, in whole or
in part, at certain redemption prices.
 
  Each share of Series I Preferred Stock is convertible into shares of Class A
Common Stock at the option of the holder at a conversion rate equal to $250.00
(the original liquidation preference of the shares of Series I Preferred
Stock), divided by the conversion price, except that, if shares of Series I
Preferred Stock are called for redemption or the Company elects to issue Series
I Exchange Debentures in exchange for the Series I Preferred Stock, the
conversion right will terminate at the close of business five business days
prior to the date fixed for redemption or exchange. The initial conversion
price is $67.44 per share. The conversion price is subject to adjustment (under
formulas set forth in the certificate of designations for the Series I
Preferred Stock) in certain events, including (a) the issuance of Class A
Common Stock as a dividend or distribution on any class of the capital stock of
the Company; (b) subdivisions, reclassifications and combinations of the Class
A Common Stock; (c) the issuance to all holders of Class A Common Stock of
certain rights or warrants entitling them to subscribe for or purchase Class A
Common Stock at less than the current market price (as defined in the
certificate of designations for the Series I Preferred Stock); and (d) certain
distributions to all holders of Class A Common Stock of capital stock or
evidences of indebtedness of the Company or cash or other assets of the
Company.
 
  In case of (i) any consolidation of the Company with, or merger of the
Company into, any other entity, (ii) any merger of another entity into the
Company (other than a merger which does not result in any reclassification,
conversion, exchange or cancellation of outstanding shares of Class A Common
Stock of the Company), or (iii) any sale or transfer of all or substantially
all of the assets of the Company, subject to certain exceptions set forth in
the certificate of designations for the Series I Preferred Stock, each holder
of a share of Series I Preferred Stock then outstanding shall have the right
thereafter to convert their shares of Series I Preferred Stock only into the
kind and amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of
Class A Common Stock of
 
                                       42
<PAGE>
 
the Company into which such share of Series I Preferred Stock might have been
converted immediately prior to such consolidation, merger, sale or transfer.
 
  The Series I Preferred Stock has a special conversion right that becomes
effective upon the occurrence of certain types of significant transactions
affecting ownership or control of the Company or the market for the Class A
Common Stock. In the event of any liquidation, dissolution or winding-up of the
Company, after payment or processing for payment of the debts and other
liabilities of the Company and of liquidation preferences in respect of any
Series I Senior Stock, holders of Series I Preferred Stock will be entitled to
receive out of the remaining net assets of the Company, if any, a preferential
amount equal to $250.00 per share (equivalent to $25.00 per depositary share),
plus all accumulated and unpaid dividends thereon to the date fixed for
liquidation, dissolution or winding-up of the Company (including an amount
equal to a prorated dividend from the last dividend payment date to the date
fixed for liquidation, dissolution or winding-up), before any distribution is
made on any Series I Junior Stock, including, without limitation, on any Common
Stock. If, upon any voluntary or involuntary liquidation, dissolution or
winding-up of the Company, the amounts payable with respect to the Series I
Preferred Stock and all other Series I Parity Stock are not paid in full, the
holders of the Series I Preferred Stock and the Series I Parity Stock will
share equally and ratably in any distribution of assets of the Company in
proportion to the full liquidation preference to which each is entitled. After
payment of the full amount of the liquidation preferences to which they are
entitled, the holders of shares of Series I Preferred Stock will not be
entitled to any further participation in any distribution of assets of the
Company. Neither the sale, conveyance, exchange or transfer (for cash, shares
of stock, securities or other consideration) of all or substantially all of the
property or assets of the Company nor the consolidation or merger of the
Company with one or more corporations shall be deemed to be a liquidation,
dissolution or winding-up of the Company.
 
  Holders of the Series I Preferred Stock will have no voting rights with
respect to general corporate matters except as provided by law or as set forth
in the certificate of designations. The certificate of designations provides
that if dividends on the Series I Preferred Stock are in arrears and unpaid for
six quarterly periods (whether or not consecutive), then the number of
directors constituting the Board of Directors will be adjusted to permit the
holders of the majority of the then outstanding Series I Preferred Stock,
voting as a class, to elect one director and a second director if the right to
elect a second director is required by the American Stock Exchange or any other
national securities exchange on which the Company elects to list the Class A
Common Stock or by the requirements of the Nasdaq National Market System if the
Company elects to have the Class A Common Stock traded thereon. Such voting
rights will continue until such time as all dividends in arrears on the Series
I Preferred Stock are paid in full, at which time the term of the directors
elected pursuant to the provisions of this paragraph shall terminate. Such
event described above is referred to herein as a "Series I Voting Rights
Triggering Event".
 
  Any vacancy occurring in the office of the director elected by holders of the
Series I Preferred Stock may be filled by the remaining director, if any, or
otherwise by the departing director unless and until such vacancy shall be
filled by such holders.
 
  The certificate of designations also provides that the Company will not
authorize any class of Series I Senior Stock without the affirmative vote or
consent of holders of at least 66 2/3% of the shares of Series I Preferred
Stock then outstanding, voting or consenting, as the case may be, separately as
one class. The certificate of designations also provides that the Company may
not amend the certificate of designations so as to affect adversely the
specified rights, preferences, privileges or voting rights of holders of shares
of the Series I Preferred Stock, or authorize the issuance of any additional
shares of Series I Preferred Stock, without the affirmative vote or consent of
the holders of at least 66 2/3% of the outstanding shares of Series I Preferred
Stock, voting or consenting, as the case may be, as one class. The holders of
at least 66 2/3% of the outstanding shares of Series I Preferred Stock, voting
or consenting, as the case may be, as one class, may also waive compliance with
any provision of the certificate of designations. The certificate of
designations also provides that (a) the creation, authorization, existence or
issuance of any shares of Series I Parity Stock or Series I Junior Stock or (b)
the increase or decrease in the amount of authorized capital stock of any
class, including
 
                                       43
<PAGE>
 
any preferred stock, shall not require the consent of the holders of Series I
Preferred Stock and shall not be deemed to affect adversely the rights,
preferences, privileges or voting rights of holders of shares of Series I
Preferred Stock.
 
  Without the affirmative vote or consent of the holders of a majority of the
issued and outstanding shares of Series I Preferred Stock, the Company may not
consolidate or merge with or into, or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its assets to, any person
unless: (a) the entity formed by such consolidation or merger (if other than
the Company) or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made (the "resulting entity") shall be a
corporation organized or existing under the laws of the United States or any
State thereof or the District of Columbia; (b) the Series I Preferred Stock
shall remain unchanged or be converted into or exchanged for and shall become
shares of such resulting entity, having in respect of such resulting entity the
same (or more favorable) powers, preferences and relative participating,
optional or other special rights, and the same (or more favorable)
qualifications, limitations or restrictions thereon, that the Series I
Preferred Stock had immediately prior to such transaction (provided that (i)
if, in accordance with the certificate of designations for the Series I
Preferred Stock, the Series I Preferred Stock shall become convertible into a
different amount or type of securities, cash or other property, such change
shall not be deemed to be a change in the powers, preferences and relative
participating, optional or other special rights of the Series I Preferred Stock
and (ii) the fact that the resulting entity has authorized or outstanding any
securities other than Series I Senior Stock, shall not be deemed to be a change
in the powers, preferences and relative participating, optional or other
special rights of the Series I Preferred Stock); and (c) immediately after
giving effect to such transaction, no Series I Voting Rights Triggering Event
shall have occurred or be continuing; provided, however, that the foregoing
shall not be applicable to a transaction or event that constitutes a "Change of
Control", as defined in the certificate of designations for the Series I
Preferred Stock.
 
  Series L Preferred Stock and Series M Preferred Stock. The Series L Preferred
Stock, with respect to dividends and distributions upon the liquidation,
winding-up and dissolution of the Company, ranks (i) senior to all classes of
Common Stock and each other class of capital stock or series of preferred stock
established by the Board of Directors (except as set forth below) which does
not expressly provide that it ranks senior to the Series L Preferred Stock as
to dividends and distributions upon the liquidation, winding-up and dissolution
of the Company (collectively referred to as "Series L Junior Stock"); (ii) on a
parity with the Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series G Preferred Stock, Series H Preferred Stock, Series I
Preferred Stock, Series M Preferred Stock and any other class of capital stock
or series of preferred stock issued by the Company established after the
initial issuance of the Series L Preferred Stock by the Board of Directors, the
terms of which expressly provide that such class or series will rank on a
parity with the Series L Preferred Stock as to dividends and distributions upon
the liquidation, winding-up and dissolution of the Company (collectively
referred to as "Series L Parity Securities"); and (iii) junior to each class of
capital stock or series of preferred stock issued by the Company established
after the initial issuance of Series L Preferred Stock by the Board of
Directors, the terms of which specifically provide that such class or series
will rank senior to the Series L Preferred Stock as to dividends and
distributions upon the liquidation, winding-up or dissolution of the Company
(collectively referred to as "Series L Senior Securities").
 
  No full dividends may be declared or paid or funds set apart for the payment
of dividends on any Series L Parity Securities for any period unless full
cumulative dividends shall have been paid or set apart for such payment on the
Series L Preferred Stock. If full dividends are not so paid, the Series L
Preferred Stock shall share dividends pro rata with the Series L Parity
Securities. Subject to certain exceptions set forth in the certificate of
designations for the Series L Preferred Stock, no dividends may be paid or set
apart for such payment on Series L Junior Stock (except dividends on Series L
Junior Stock in additional shares of Series L Junior Stock), and no Series L
Junior Stock may be repurchased, redeemed or otherwise retired nor may funds by
set apart for payment with respect thereto, if full dividends have not been
paid on the Series L Preferred Stock.
 
 
                                       44
<PAGE>
 
  The Company may redeem the Series L Preferred Stock at any time after April
1, 2003, in whole or in part, at certain redemption prices. In addition, the
Company may redeem shares of Series L Preferred Stock at any time before April
1, 1999 at a redemption price per share equal to the liquidation preference of
$10,000, plus accumulated and unpaid dividends plus a premium of $1,000 per
share, out of the net proceeds of the sale of Series L Junior Stock to a
Strategic Equity Investor or a public offering of Class A Common Stock.
Furthermore, the Company may, at its option, prior to April 1, 2003, redeem the
Series L Preferred Stock at any time within 180 days, at certain redemption
prices, after a Change of Control (as defined in the certificate of
designations for the Series L Preferred Stock). On April 1, 2008, the Company
will be required to redeem all outstanding shares of Series L Preferred Stock
out of funds legally available therefrom.
 
  The Company may, at its option, on any scheduled dividend payment date,
exchange the Series L Preferred Stock for the Company's 11 1/8% Senior
Subordinated Debentures due 2008.
 
  In the event of any liquidation, winding-up or dissolution of the Company,
holders of Series L Preferred Stock will be entitled to receive a preferential
amount equal to $10,000 per share, plus all accumulated and unpaid dividends
thereon to the date fixed for liquidation, dissolution or winding-up of the
Company (including an amount equal to a prorated dividend from the last
dividend payment date to the date fixed for liquidation, dissolution or winding
up), before any distribution is made on the Series L Junior Stock. If upon any
voluntary or involuntary liquidation, dissolution or winding-up of the Company,
the amounts payable with respect to the Series L Preferred Stock and all other
Series L Parity Securities are not paid in full, the holders of the Series L
Preferred Stock and the Series L Parity Securities will share equally and
ratably in any distribution of assets of the Company in proportion to the full
liquidation preference to which each is entitled. After payment of the full
amount of the liquidation preferences to which they are entitled, the holders
of shares of Series L Preferred Stock will not be entitled to any further
participation in any distribution of assets of the Company. Neither the sale,
conveyance, exchange or transfer (for cash, shares of stock, securities or
other consideration) of all or substantially all the property or assets of the
Company nor the consolidation or merger of the Company with one or more
corporations shall be deemed a liquidation, dissolution or winding-up of the
Company.
 
  Holders of the Series L Preferred Stock have no voting rights with respect to
general corporate matters except as provided by law or as set forth in the
certificate of designations therefor. The certificate of designations for the
Series L Preferred Stock provides that (a) dividends on the Series L Preferred
Stock are in arrears and unpaid (and if after April 1, 2001, such dividends are
not paid in cash) for six quarterly periods (whether or not consecutive), or
(b) the Company fails to discharge its redemption obligation to redeem the
Series L Preferred Stock on April 1, 2008, the number of directors constituting
the Board of Directors will be adjusted to permit the holders of a majority of
the then outstanding Series L Preferred Stock and the Series M Preferred Stock,
voting or consenting, as the case may be, separately as a single class, to
elect a director. Such voting rights will continue until such time as all
dividends in arrears on the Series L Preferred Stock are paid in full (and in
the case of dividends payable after April 1, 2001, paid in cash) and any
failure, breach or default referred to in clause (b) is remedied, at which time
the term of the directors elected pursuant to the provisions of this paragraph
shall terminate. Each such event described in clauses (a) and (b) above is
referred to herein as a "Series L Voting Rights Triggering Event".
 
  The certificate of designations for the Series L Preferred Stock also
provides that the Company will not authorize any class of Series L Senior
Securities without the affirmative vote or consent of holders of at least a
majority of the shares of Series L Preferred Stock and Series M Preferred Stock
then outstanding, voting or consenting, as the case may be, separately as a
single class. The Company may not amend the certificate of designations for the
Series L Preferred Stock so as to affect adversely the specified rights,
preferences, privileges or voting rights of holders of shares of the Series L
Preferred Stock, or authorize the issuance of any additional shares of Series L
Preferred Stock, without the affirmative vote or consent of the holders of at
least a majority of the outstanding shares of Series L Preferred Stock and
Series M Preferred Stock, voting or consenting, as the case may be, separately
as a single class.
 
 
                                       45
<PAGE>
 
  Without the affirmative vote or consent of a majority of the issued and
outstanding shares of Series L Preferred Stock and Series M Preferred Stock,
voting or consenting, as the case may be, separately as a single class, the
Company may not consolidate or merge with or into, or sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its assets
to, any person unless: (a) the entity formed by such consolidation or merger
(if other than the Company) or to which such sale, assignment, transfer, lease,
conveyance or other disposition shall have been made shall be a corporation
organized and existing under the laws of the United States or any State thereof
or the District of Columbia; (b) the Series L Preferred Stock shall be
converted into or exchanged for and shall become shares of such successor,
transferee or resulting corporation, having in respect of such successor,
transferee or resulting corporation the same powers, preferences and relative
participating, optional or special rights, and the qualifications, limitations
or restrictions thereon, that the Series L Preferred Stock had immediately
prior to such transactions; and (c) immediately after giving effect to such
transaction, no Series L Voting Rights Triggering Event shall have occurred and
be continuing. Notwithstanding the foregoing, the Company may consolidate or
merge with or into, or sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its assets to, any person if the Company
makes adequate provision (i) prior to April 1, 2003, to redeem the Series L
Preferred Stock after a Change of Control (as defined in the certificate of
designations for the Series L Preferred Stock) or (ii) on or after April 1,
2003, to redeem the Series L Preferred Stock at the applicable redemption price
set forth in the certificate of designations therefor.
 
  The Series M Preferred Stock will have the same terms in all material
respects as the Series L Preferred Stock, except that the Series M Preferred
Stock will not contain terms restricting the transfer thereof.
 
  DESCRIPTION OF NEW DEPOSITARY SHARES, SERIES M PREFERRED STOCK AND EXCHANGE
                                   DEBENTURES
 
NEW DEPOSITARY SHARES
 
  The following summary description of the New Depositary Shares offered hereby
does not purport to be complete and is subject to, and qualified in its
entirety by reference to, the Deposit Agreement referred to below.
 
 GENERAL
 
  Each New Depositary Share represents a one one-hundredth interest in a share
of Series M Preferred Stock. The shares of Series M Preferred Stock underlying
the New Depositary Shares will be deposited with The First National Bank of
Boston, as Depositary (the "Depositary"), under a Deposit Agreement (the
"Deposit Agreement"), among the Company, the Depositary and all holders from
time to time of depositary receipts issued by the Depositary thereunder (the
"Depositary Receipts"). The Company does not plan to apply to list the Old
Depositary Shares, the New Depositary Shares, the Series L Preferred Stock or
the Series M Preferred Stock on any national securities exchange or any similar
system of automated dissemination of quotations of securities. Accordingly, the
Company does not expect that there will be any public trading market for the
Old Depositary Shares, the New Depositary Shares, the Series L Preferred Stock
or the Series M Preferred Stock. The New Depositary Shares will be evidenced by
Depositary Receipts.
 
  Subject to the terms of the Deposit Agreement, each owner of a New Depositary
Share will be entitled through the Depositary, in proportion to the one one-
hundredth interest in a share of Series M Preferred Stock underlying such New
Depositary Share, to all the rights, preferences and privileges of a share of
Series M Preferred Stock (including dividend, voting, redemption, conversion
and liquidation rights), and will be subject to all of the limitations of the
fractional share of Series M Preferred Stock represented thereby, which are
summarized below under "Series M Preferred Stock". Since each share of Series M
Preferred Stock entitles the holder thereof to one vote on matters on which the
Series M Preferred Stock is entitled to vote, each New Depositary Share will,
in effect, entitle the holder thereof to one one-hundredth of a vote thereon,
rather than one full vote. See "Series M Preferred Stock--Voting Rights" below.
 
                                       46
<PAGE>
 
  The Depositary will act as transfer agent and registrar and paying agent with
respect to the Depositary Shares.
 
 ISSUANCE OF DEPOSITARY RECEIPTS AND WITHDRAWAL OF SERIES M PREFERRED STOCK
FROM DEPOSIT
 
  Immediately following the issuance by the Company of the shares of Series M
Preferred Stock to be represented by the New Depositary Shares, the Company
will deposit such shares of Series M Preferred Stock with the Depositary, which
will then issue and deliver the Depositary Receipts in exchange for Old
Depositary Receipts. Depositary Receipts will be issued evidencing only whole
Depositary Shares.
 
  Upon surrender of the Depositary Receipts at the Corporate Office (as defined
in the Deposit Agreement) of the Depositary (or such other office as the
Depositary may designate), the owner of the New Depositary Shares evidenced
thereby is entitled at such office to certificates evidencing the number of
shares of Series M Preferred Stock (but only in whole shares of Series M
Preferred Stock) represented by such Depositary Receipts. If the Depositary
Receipts delivered by the holder evidence a number of New Depositary Shares in
excess of the number of whole shares of Series M Preferred Stock to be
withdrawn, the Depositary will deliver to such holder at the same time a new
Depositary Receipt evidencing such excess number of New Depositary Shares.
 
 DIVIDENDS AND OTHER DISTRIBUTIONS
 
  The Depositary will distribute all cash dividends, dividends paid in New
Depositary Shares representing fully paid and nonassessable shares of Series M
Preferred Stock or other cash distributions received in respect of the Series M
Preferred Stock to the record holders of New Depositary Shares representing
such Series M
Preferred Stock in proportion to the numbers of such New Depositary Shares
owned by such holders on the relevant record date. In the event of a
distribution other than in cash, the Depositary will distribute property
received by it to the record holders of New Depositary Shares entitled thereto,
unless the Depositary determines that it is not feasible to make such
distribution, in which case the Depositary may, with the approval of the
Company, sell such property and distribute the net proceeds from such sale to
such holders.
 
 REDEMPTION OF NEW DEPOSITARY SHARES
 
  If the Series M Preferred Stock underlying the New Depositary Shares is
subject to redemption, the New Depositary Shares will be redeemed from the
proceeds received by the Depositary resulting from the redemption, in whole or
in part, of such Series M Preferred Stock held by the Depositary. The
redemption price per New Depositary Share will be equal to the applicable
fraction of the redemption price per share payable with respect to such Series
M Preferred Stock. If less than all the New Depositary Shares are to be
redeemed, the New Depositary Shares to be redeemed will be selected by lot or
pro rata.
 
  After the date fixed for redemption (which will be the same date as the
redemption date for the Series M Preferred Stock), the New Depositary Shares so
called for redemption will no longer be deemed to be outstanding and all rights
of the holders of the New Depositary Shares will cease, except the right to
receive the moneys payable upon such redemption and any money or other property
to which the holders of such New Depositary Shares were entitled upon such
redemption upon surrender to the Depositary of the Depositary Receipts
evidencing such New Depositary Shares.
 
 VOTING
 
  Upon receipt of notice of any meeting at which the holders of the Series M
Preferred Stock are entitled to vote, the Depositary will mail the information
contained in such notice of meeting to the record holders of the New Depositary
Shares relating to such Series M Preferred Stock. Each record holder of such
New Depositary Shares on the record date (which will be the same date as the
record date for the Series M Preferred Stock) will be entitled to instruct the
Depositary as to the exercise of the voting rights pertaining to
 
                                       47
<PAGE>
 
the number of shares of Series M Preferred Stock underlying such holder's New
Depositary Shares. The Depositary will endeavor, insofar as practicable, to
vote the number of shares of Series M Preferred Stock underlying such New
Depositary Shares in accordance with such instructions, and the Company will
agree to take all action which may be deemed necessary by the Depositary in
order to enable the Depositary to do so. The Depositary will abstain from
voting shares of Series M Preferred Stock to the extent the Depositary does not
receive specific instructions from the holders of New Depositary Shares
relating to such shares.
 
 AMENDMENT OF THE DEPOSIT AGREEMENT
 
  The form of Depositary Receipt evidencing the New Depositary Shares and any
provision of the Deposit Agreement may at any time be amended by agreement
between the Company and the Depositary. However, any amendment which materially
and adversely alters the rights of the holders of New Depositary Receipts will
not be effective unless such amendment has been approved by the holders of at
least 66 2/3% of the New Depositary Shares then outstanding. Every holder of an
outstanding Depositary Receipt at the time any amendment becomes effective will
be deemed, by continuing to hold such Depositary Receipt, to consent and agree
to such amendment and to be bound by the Deposit Agreement as amended thereby.
In no event will any amendment impair the right, subject to the provisions of
the Deposit Agreement, of any owner of any New Depositary Shares to surrender
any Depositary Receipt evidencing such New Depositary Shares to the Depositary
with instructions to deliver to the holder the Series M Preferred Stock and all
money, and other property, if any, represented thereby, except in order to
comply with mandatory provisions of applicable law or the rules and regulations
of any governmental body, agency or commission, the National Association of
Securities Dealers, Inc. or any applicable stock exchange.
 
 CHARGES OF DEPOSITARY
 
  The Company will pay all transfer and other taxes and governmental charges
that arise solely from the existence of the depositary arrangements. The
Company will pay the charges of the Depositary in connection with the initial
deposit of the Series M Preferred Stock and any redemption of the Series M
Preferred Stock. Holders of New Depositary Shares will pay all other transfer
and other taxes and governmental charges and, in addition, such other charges
as are expressly provided in the Deposit Agreement to be for their accounts.
 
 MISCELLANEOUS
 
  The Depositary will forward to the holders of New Depositary Shares all
reports and communications from the Company which the Company is required to
furnish to the holders of the Series M Preferred Stock.
 
  Neither the Depositary nor the Company will be liable if it is prevented or
delayed by law or any circumstances beyond its control in performing its
obligations under the Deposit Agreement. The obligations of the Company and the
Depositary under the Deposit Agreement will be limited to performance in good
faith of their duties thereunder, and they will not be obligated to prosecute
or defend any legal proceedings in respect of any New Depositary Shares or
Series M Preferred Stock unless satisfactory indemnity is furnished. They may
rely upon written advice of counsel or accountants, or information provided by
persons presenting Series M Preferred Stock for deposit, holders of New
Depositary Shares or other persons believed to be competent and on documents
believed to be genuine.
 
 RESIGNATION AND REMOVAL OF DEPOSITARY; TERMINATION OF THE DEPOSIT AGREEMENT
 
  The Depositary may resign at any time by delivering to the Company notice of
its election to do so, and the Company may at any time remove the Depositary,
any such resignation or removal to take effect upon the appointment of a
successor Depositary and its acceptance of such appointment. Such successor
Depositary will be appointed by the Company within 45 days after delivery of
the notice of resignation or removal. The Deposit Agreement may be terminated
at the direction of the Company or by the Depositary if
 
                                       48
<PAGE>
 
a period of 45 days shall have expired after the Depositary has delivered to
the Company written notice of its election to resign and a successor depositary
shall not have been appointed. Upon termination of the Deposit Agreement, the
Depositary will discontinue the transfer of Depositary Receipts, will suspend
the distribution of dividends to the holders thereof and will not give any
further notices (other than notice of such termination) or perform any further
acts under the Deposit Agreement, except that the Depositary will continue to
collect dividends and other distributions pertaining to the Series M Preferred
Stock, will sell rights, preferences or privileges as provided in the Deposit
Agreement and will continue to deliver Series M Preferred Stock certificates
together with such dividends and distributions and the net proceeds of any
sales of rights, preferences, privileges or other property in exchange for
Depositary Receipts surrendered. At any time after the expiration of two years
from the date of termination, the Depositary may sell the Series M Preferred
Stock and hold the proceeds of such sale, without interest, for the benefit of
the holders of Depositary Receipts who have not then surrendered their
Depositary Receipts. After making such sale, the Depositary will be discharged
from all obligations under the Deposit Agreement except to account for such
proceeds.
 
SERIES M PREFERRED STOCK
 
  The Series M Preferred Stock will be issued pursuant to a certificate of
designations (the "Certificate of Designations"). The summary contained herein
of certain provisions of the Series M Preferred Stock does not purport to be
complete and is qualified in its entirety by reference to the provisions of the
Certificate of Designations. The definitions of certain terms used in the
Certificate of Designations and in the following summary are set forth below
under "--Definitions".
 
 GENERAL
 
  The Company will (assuming the exchange of all outstanding Old Depositary
Shares for New Depositary Shares) authorize the issuance of up to 115,000
shares of Series M Preferred Stock, which will consist of 65,923.79 shares of
Series M Preferred Stock represented by New Depositary Shares exchanged for Old
Depositary Shares plus 49,076.21 additional shares of Series M Preferred Stock
which may be used to pay dividends on the Series M Preferred Stock if the
Company elects to pay dividends in additional shares of Series M Preferred
Stock, and will file a Certificate of Designations with respect thereto with
the Secretary of State of the State of Delaware as required by Delaware law.
The Series L Preferred Stock surrendered will be retired and cancelled and
cannot be reissued. Accordingly, issuance of the Series M Preferred Stock will
not result in any change in capitalization of the Company. The Series M
Preferred Stock when issued in accordance with the terms of the Exchange Offer,
will be fully paid and non-assessable, and the holders thereof will have no
subscription or preemptive rights related thereto.
 
 RANKING
 
  The Series M Preferred Stock represented by the New Depositary Shares, with
respect to dividends and distributions upon the liquidation, winding-up and
dissolution of the Company, will rank (i) senior to all classes of Common Stock
and each other class of capital stock or series of preferred stock established
by the Board of Directors which does not expressly provide that it ranks senior
to or on a parity with the Series M Preferred Stock as to dividends and
distributions upon the liquidation, winding-up and dissolution of the Company
(collectively referred to as "Junior Stock"); (ii) on a parity with the Series
L Preferred Stock and the Company's Series B Preferred Stock, Series C
Preferred Stock, Series D Preferred Stock (which may be issued in exchange for
shares of the Series C Preferred Stock), Series G Preferred Stock, Series H
Preferred Stock, Series I Preferred Stock and any other class of capital stock
or series of preferred stock issued by the Company established after the
initial issuance of the Series M Preferred Stock by the Board of Directors, the
terms of which expressly provide that such class or series will rank on a
parity with the Series M Preferred Stock as to dividends and distributions upon
the liquidation, winding-up and dissolution of the Company (collectively
referred to as "Parity Securities"); and (iii) junior to each class of capital
stock or series of preferred stock issued by the Company established after the
initial issuance of the Series M Preferred Stock
 
                                       49
<PAGE>
 
by the Board of Directors, the terms of which specifically provide that such
class or series will rank senior to the Series M Preferred Stock as to
dividends and distributions upon the liquidation, winding-up and dissolution of
the Company (collectively referred to as "Senior Securities").
 
  The Company may not issue any new class of Senior Securities without the
approval of the holders of at least a majority of the shares of Series L
Preferred Stock and Series M Preferred Stock then outstanding, voting or
consenting, as the case may be, as a single class.
 
 DIVIDENDS
 
  Holders of Series M Preferred Stock are entitled, when declared by the Board
of Directors, out of funds legally available therefor, to receive dividends on
each outstanding share of the Series M Preferred Stock, at the annual rate of
11 1/8% per share of Series M Preferred Stock. Dividends on the Series M
Preferred Stock will accumulate from the Accrual Date and are payable quarterly
in arrears on January 1, April 1, July 1 and October 1 of each year. Holders of
Series L Preferred Stock whose shares of Series L Preferred Stock are accepted
for exchange will be deemed to have waived the right to receive any payment in
respect of dividends on the Series L Preferred Stock accumulated from the
Accrual Date until the date of the issuance of the Series M Preferred Stock.
Consequently, holders who exchange their Series L Preferred Stock for Series M
Preferred Stock will receive the same dividend payment on the next dividend
payment date (expected to be July 1, 1996) that they would have received had
they not accepted the Exchange Offer, except that if such dividend is not paid
in cash, it will be paid in shares of Series M Preferred Stock instead of
Series L Preferred Stock. Before April 1, 2001, dividends may, at the option of
the Company, be paid either in cash or fully paid and non-assessable shares of
Series M Preferred Stock with an aggregate liquidation preference equal to the
amount of such dividend. On and after April 1, 2001, dividends may only be paid
in cash. If any dividend (or portion thereof) payable on any dividend payment
date on or after April 1, 2001 is not paid in full in cash on the dividend
payment date therefor, the amount of such dividend that is payable and that is
not paid in cash on such date will increase at the rate of 11 1/8% per annum
from such dividend payment date until paid in full.
 
  No full dividends may be declared or paid or funds set apart for the payment
of dividends on any Parity Securities for any period unless full cumulative
dividends shall have been paid or set apart for such payment on the Series M
Preferred Stock. If full dividends are not so paid, the Series M Preferred
Stock shall share dividends pro rata with the Parity Securities. No dividends
may be paid or set apart for such payment on Junior Stock (except dividends on
Junior Stock in additional shares of Junior Stock), and no Junior Stock may be
repurchased, redeemed or otherwise retired nor may funds be set apart for
payment with respect thereto, if full dividends have not been paid on the
Series M Preferred Stock, except for (i) any conversion of Class B Common Stock
of the Company into Class A Common Stock of the Company, (ii) prior to April 1,
2001, the occurrence of the Rainbow Spin-Off, (iii) repurchases of Common Stock
issued under the Company's stock incentive programs from employees of the
Company, and (iv) dividends or distributions payable-in-kind in additional
shares of, or warrants, rights, calls or options exercisable for or convertible
into additional shares of Junior Stock. See "Risk Factors--Risks Related to the
Securities--Restrictions on Company's Ability to Pay Dividends on the Series L
Preferred Stock and Series M Preferred Stock".
 
 OPTIONAL REDEMPTION
 
  The Company at its option may, but shall not be required to, redeem the
Series M Preferred Stock (subject to contractual and other restrictions with
respect thereto and to the legal availability of funds therefor) at any time
after April 1, 2003, in whole or in part, at the redemption prices (expressed
in percentage of liquidation preference) set forth below together with all
accumulated and unpaid dividends from the last

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

      2006 and thereafter............................................  100.000
</TABLE>
 
  In addition, the Company may redeem shares of Series M Preferred Stock having
an aggregate liquidation preference of up to 50% of the shares of Series M
Preferred Stock then outstanding at any time before April 1, 1999 at a
redemption price per share equal to the liquidation preference of $10,000 per
share (equivalent to $100 per New Depositary Share), plus accumulated and
unpaid dividends plus a premium of $1,000 per share (equivalent to $10 per New
Depositary Share) out of the net proceeds of the sale of Junior Stock to a
Strategic Equity Investor or a public offering of Class A Common Stock;
provided that following such redemption, at least 3,250,000 Depositary Shares
(representing at least 50% of the amount of Depositary Shares initially issued)
shall remain outstanding.
 
  Furthermore, the Company may, at its option, prior to April 1, 2003, redeem
the Series M Preferred Stock, in whole but not in part, at any time within 180
days after a Change of Control (as defined herein), at a redemption price per
share equal to the sum of (i) the liquidation preference of $10,000 per share
(equivalent to $100 per New Depositary Share) plus (ii) accumulated and unpaid
dividends to the date of redemption plus (iii) the Make-Whole Premium (as
defined herein), which is based on a discount rate equal to the Treasury Rate
(as defined herein) plus 50 basis points.
 
  In the event of partial redemptions of Series M Preferred Stock, the shares
to be redeemed will be determined pro rata or by lot, as determined by the
Company, except that the Company may redeem such shares held by any holders of
fewer than 100 shares (or shares held by holders who would hold less than 100
shares as a result of such redemption), as may be determined by the Company.
 
 MANDATORY REDEMPTION
 
  On April 1, 2008 (the "Mandatory Redemption Date"), the Company will be
required to redeem (subject to contractual and other restrictions with respect
thereto and to the legal availability of funds therefor) all outstanding shares
of Series M Preferred Stock at a price equal to the liquidation preference of
$10,000 per share (equivalent to $100 per New Depositary Share) plus all
accumulated and unpaid dividends from the last payment date to the date of
redemption. Future agreements of the Company may restrict or prohibit the
Company from redeeming the Series M Preferred Stock. See "Risk Factors--Risks
Related to the Securities--Restrictions on the Company's Ability to Pay
Dividends on Series L Preferred Stock and Series M Preferred Stock".
 
 PROCEDURE FOR REDEMPTION
 
  On and after a redemption date, unless the Company defaults in the payment of
the applicable redemption price, dividends will cease to accumulate on shares
of Series M Preferred Stock called for redemption and all rights of holders of
such shares will terminate except for the right to receive the redemption
price, without interest. The Company will send a written notice of redemption
by first class mail to each holder of record of shares of Series M Preferred
Stock, not fewer than 30 days nor more than 60 days prior to the date fixed for
such redemption. Shares of Series M Preferred Stock issued and reacquired will,
upon compliance with the applicable requirements of Delaware law, have the
status of authorized but unissued shares of preferred stock of the Company
undesignated as to series and may with any and all other
 
                                       51
<PAGE>
 
authorized but unissued shares of preferred stock of the Company be designated
or redesignated and issued or reissued, as the case may be, as part of any
series of preferred stock of the Company, except that any issuance or
reissuance of shares of Series M Preferred Stock must be in compliance with the
Certificate of Designations.
 
 EXCHANGE
 
  The Company may, at its option, on any scheduled dividend payment date,
exchange the New Depositary Shares representing the Series M Preferred Stock,
in whole but not in part, for the Exchange Debentures. See "--The Exchange
Debentures" below for the terms of the Exchange Debentures. Holders of Series M
Preferred Stock so exchanged will be entitled to receive a principal amount of
Exchange Debentures equal to $100 for each $100 of liquidation preference of
New Depositary Shares representing the Series M Preferred Stock held by such
holders at the time of exchange plus an amount per share in cash (or prior to
April 1, 2001, in principal amount of Exchange Debentures) equal to all
accumulated but unpaid dividends thereon from the last dividend payment date to
the exchange date. The Exchange Debentures will be issuable only in
denominations of $1,000 and integral multiples thereof. An amount in cash will
be paid to holders for any principal amount otherwise issuable which is less
than $1,000. Following such exchange, all dividends on the Series M Preferred
Stock will cease to accrue, the rights of the holders of Series M Preferred
Stock as stockholders of the Company shall cease and the person or persons
entitled to receive the Exchange Debentures issuable upon exchange shall be
treated as the registered holder or holders of such Exchange Debentures. Notice
of exchange will be mailed at least 30 days but not more than 60 days prior to
the date of exchange to each holder of New Depositary Shares representing the
Series M Preferred Stock. See "--The Exchange Debentures" below.
 
 LIQUIDATION PREFERENCE
 
  In the event of any liquidation, dissolution or winding-up of the Company,
holders of Series M Preferred Stock will be entitled to receive a preferential
amount equal to $10,000 per share (equivalent to $100 per New Depositary
Share), plus all accumulated and unpaid dividends thereon to the date fixed for
liquidation, dissolution or winding-up of the Company (including an amount
equal to a prorated dividend from the last dividend payment date to the date
fixed for liquidation, dissolution or winding-up), before any distribution is
made on any Junior Stock, including, without limitation, on any Common Stock.
If upon any voluntary or involuntary liquidation, dissolution or winding-up of
the Company, the amounts payable with respect to the Series M Preferred Stock
and all other Parity Securities are not paid in full, the holders of the Series
M Preferred Stock and the Parity Securities will share equally and ratably in
any distribution of assets of the Company in proportion to the full liquidation
preference to which each is entitled. After payment of the full amount of the
liquidation preferences to which they are entitled, the holders of shares of
Series M Preferred Stock will not be entitled to any further participation in
any distribution of assets of the Company. However, neither the sale,
conveyance, exchange or transfer (for cash, shares of stock, securities or
other consideration) of all or substantially all of the property or assets of
the Company nor the consolidation or merger of the Company with one or more
corporations shall be deemed to be a liquidation, dissolution or winding-up of
the Company.
 
  The Certificate of Designations for the Series M Preferred Stock does not
contain any provision requiring funds to be set aside to protect the
liquidation preference of the Series M Preferred Stock, although such
liquidation preference will be substantially in excess of the par value of such
shares of Series M Preferred Stock. In addition, the Company is not aware of
any provision of Delaware law or any controlling decision of the courts of the
State of Delaware (the state of incorporation of the Company) that requires a
restriction upon any surplus of the Company solely because the liquidation
preference of the Series M Preferred Stock will exceed its par value.
Consequently, there will be no restriction upon any surplus of the Company
solely because the liquidation preference of the Series M Preferred Stock will
exceed the par value and there will be no remedies available to holders of the
Series M Preferred Stock before or after the payment of any dividend, other
than in connection with the liquidation of the Company, solely by reason of the
fact that such dividend
 
                                       52
<PAGE>
 
would reduce any surplus of the Company to an amount less than the difference
between the liquidation preference of the Series M Preferred Stock and its par
value. See "Risk Factors--Risks Related to the Securities--Restrictions on the
Company's Ability to Pay Dividends on the Series L Preferred Stock and Series M
Preferred Stock".
 
 VOTING RIGHTS
 
  Holders of the Series M Preferred Stock will have no voting rights with
respect to general corporate matters except as provided by law or as set forth
in the Certificate of Designations. The Certificate of Designations provides
that if (a) dividends on the Series L Preferred Stock or Series M Preferred
Stock are in arrears and unpaid (and if after April 1, 2001, such dividends are
not paid in cash) for six quarterly periods (whether or not consecutive), or
(b) the Company fails to discharge its redemption obligation to redeem the
Series L Preferred Stock or Series M Preferred Stock on the Mandatory
Redemption Date, then the number of directors constituting the Board of
Directors will be adjusted to permit the holders of the majority of the then
outstanding Series L Preferred Stock and Series M Preferred Stock, voting or
consenting, as the case may be, as a single class, to elect a director. Such
voting rights will continue until such time as all dividends in arrears on the
Series L Preferred Stock and Series M Preferred Stock are paid in full (and in
the case of dividends payable after April 1, 2001, paid in cash) and any
failure, breach or default referred to in clause (b) is remedied, at which time
the term of the directors elected pursuant to the provisions of this paragraph
shall terminate. Each such event described in clauses (a) and (b) above is
referred to herein as a "Voting Rights Triggering Event".
 
  Any vacancy occurring in the office of the director elected by holders of the
Series L Preferred Stock and Series M Preferred Stock may be filled by the
departing director unless and until such vacancy shall be filled by such
holders.
 
  The Certificate of Designations also provides that, except as stated above
under "--Ranking", the Company will not authorize any class of Senior
Securities without the affirmative vote or consent of holders of at least a
majority of the shares of Series L Preferred Stock and Series M Preferred Stock
then outstanding, voting or consenting, as the case may be, separately as a
single class. The Certificate of Designations also provides that the Company
may not amend the Certificate of Designations so as to affect adversely the
specified rights, preferences, privileges or voting rights of holders of shares
of the Series L Preferred Stock or Series M Preferred Stock, or authorize the
issuance of any additional shares of Series L Preferred Stock or Series M
Preferred Stock, without the affirmative vote or consent of the holders of at
least a majority of the outstanding shares of Series L Preferred Stock and
Series M Preferred Stock, voting or consenting, as the case may be, as a single
class. The holders of at least a majority of the outstanding shares of Series L
Preferred Stock and Series M Preferred Stock, voting or consenting, as the case
may be, as a single class, may also waive compliance with any provision of the
Certificate of Designations. The Certificate of Designations also provides
that, except as set forth above, (a) the creation, authorization or issuance of
any shares of Parity Securities or Junior Stock or (b) the increase or decrease
in the amount of authorized capital stock of any class, including any preferred
stock, shall not require the consent of the holders of Series L Preferred Stock
or Series M Preferred Stock and shall not be deemed to affect adversely the
rights, preferences, privileges or voting rights of holders of shares of Series
L Preferred Stock or Series M Preferred Stock.
 
  Under Delaware law, holders of a class of preferred stock will be entitled to
vote as a class upon a proposed amendment to the certificate of incorporation,
whether or not entitled to vote thereon by the certificate of incorporation, if
the amendment would increase or decrease the aggregate number of authorized
shares of such class, increase or decrease the par value of the shares of such
class, or alter or change the powers, preferences or special rights of the
shares of such class so as to affect them adversely. The Certificate of
Designations will expressly provide that any such vote will be taken with
respect to the Series L Preferred Stock and Series M Preferred Stock, voting or
consenting, as the case may be, as a single class.
 
                                       53
<PAGE>
 
 MERGER, CONSOLIDATION AND SALE OF ASSETS
 
  Without the affirmative vote or consent of the holders of a majority of the
issued and outstanding shares of Series L Preferred Stock and Series M
Preferred Stock, the Company may not consolidate or merge with or into, or
sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of its assets to, any Person unless: (a) the entity formed by
such consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made shall be a corporation organized or existing under the laws of the United
States or any State thereof or the District of Columbia; (b) any and all
outstanding shares of Series L Preferred Stock and Series M Preferred Stock
shall be converted into or exchanged for and shall become shares of such
successor, transferee or resulting corporation, having in respect of such
successor, transferee or resulting corporation the same powers, preferences and
relative participating, optional or other special rights, and the
qualifications, limitations or restrictions thereon, that the Series L
Preferred Stock or Series M Preferred Stock, as the case may be, had
immediately prior to such transaction; and (c) immediately after giving effect
to such transaction, no Voting Rights Triggering Event shall have occurred or
be continuing. Notwithstanding the foregoing, the Company may consolidate or
merge with or into, or sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its assets to, any Person if the Company
makes adequate provision (i) prior to April 1, 2003, to redeem the Series L
Preferred Stock and Series M Preferred Stock after a Change of Control or (ii)
on or after April 1, 2003, to redeem the Series L Preferred Stock and Series M
Preferred Stock at the applicable redemption price set forth herein.
 
 COVENANT TO REPORT
 
  Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13 or Section 15(d) of the Exchange Act, the Company
will file with the Commission and provide the Transfer Agent and the holders of
the Series M Preferred Stock with all information, documents and reports
specified in Section 13 and Section 15(d) of the Exchange Act.
 
 TRANSFER AGENT AND REGISTRAR
 
  The First National Bank of Boston is the transfer agent and registrar for the
Series M Preferred Stock.
 
THE EXCHANGE DEBENTURES
 
  The Exchange Debentures will be issued under an Indenture dated as of
February 15, 1996 (the "Exchange Indenture"), between the Company and The Bank
of New York, as trustee (the "Trustee"). The Exchange Indenture is subject to
and is governed by the Trust Indenture Act of 1939, as amended. The following
summaries of certain provisions of the Exchange Indenture do not purport to be
complete, and where reference is made to particular provisions of the Exchange
Indenture, such provisions, including the definitions of certain terms, are
incorporated by reference as a part of such summaries or terms, which are
qualified in their entirety by such reference. The definitions of certain
capitalized terms used in the Exchange Indenture and in the following summary
are set forth below under "Certain Definitions".
 
  The Exchange Debentures will be unsecured obligations of the Company and will
be limited in aggregate principal amount to the aggregate liquidation
preference of the Series L Preferred Stock and Series M Preferred Stock, plus
accumulated and unpaid dividends on the date of exchange of the Series L
Preferred Stock or Series M Preferred Stock, as the case may be, into Exchange
Debentures (plus any additional Exchange Debentures issued in lieu of cash
interest as described herein). The Exchange Debentures will be issued only in
fully registered form without coupons, in denominations of $1,000 or any
integral multiple thereof (other than with respect to additional Exchange
Debentures issued in lieu of cash interest as described herein). The Exchange
Debentures will be subordinated to all existing and future Senior Indebtedness
of the Company.
 
                                       54
<PAGE>
 
  The Exchange Debentures will mature on April 1, 2008. Each Exchange Debenture
will accrue interest at the dividend rate of the Series L Preferred Stock or
Series M Preferred Stock, as the case may be, from the Exchange Debenture Issue
Date or from the most recent interest payment date to which interest has been
paid or provided for.
 
  Interest will be payable semi-annually in cash (or, on or prior to April 1,
2001, in additional Exchange Debentures having a principal amount equal to the
cash interest otherwise payable, or in a combination of cash and Exchange
Debentures, at the option of the Company) in arrears on January 1 and July 1 of
each year, commencing with the first such date after the Exchange Debenture
Issue Date. Interest on the Exchange Debentures will be computed on the basis
of a 360-day year of twelve 30-day months and the actual number of days
elapsed.
 
  Principal of and premium, if any, and interest on the Exchange Debentures
will be payable, and the Exchange Debentures will be exchangeable and
transferable, at the office or agency of the Company in The City of New York
(which initially will be the Corporate Trust Office of the Trustee); provided,
however, that payment of interest, to the extent paid in cash, may be made at
the option of the Company by check mailed to the person entitled thereto as
shown on the Register of the Exchange Debentures. No service charge will be
made for any registration of transfer or exchange of Exchange Debentures,
except for any tax or other governmental charge that may be imposed in
connection therewith.
 
  The Exchange Indenture will not contain any provisions that limit the ability
of the Company to incur indebtedness or that afford Holders of the Exchange
Debentures protection in the event of a highly leveraged or similar transaction
involving the Company, other than as described under "--Certain Covenants of
the Company--Limitation on Indebtedness".
 
 SINKING FUND
 
  The Exchange Debentures will not be entitled to the benefits of a sinking
fund.
 
 SUBORDINATION
 
  The indebtedness represented by the Exchange Debentures will be subordinated
in right of payment to the prior payment in full of all Senior Indebtedness.
(Section 1201) Upon the maturity of any Senior Indebtedness, by lapse of time,
acceleration or otherwise, or upon any payment default (with or without the
giving of notice or lapse of time or both, in accordance with the terms of the
instrument governing such Senior Indebtedness, and without any waiver or
forgiveness) with respect to any Senior Indebtedness, all obligations with
respect to such Senior Indebtedness must first be paid in full, or such payment
duly provided for, before any payment is made with respect to the Exchange
Debentures or before any acquisition of Exchange Debentures by the Company.
(Section 1202)
 
  Upon (i) a default with respect to any Senior Indebtedness (other than under
circumstances when the terms of the previous paragraph are applicable), as such
default is defined therein or in the instrument under which it is outstanding,
permitting the holders of Senior Indebtedness to accelerate the maturity
thereof, and (ii) written notice thereof ("Default Notice") given to the
Company and the Trustee by the agent or agents under the Credit Agreement,
then, unless and until such default shall have been cured or waived by the
holders of such Senior Indebtedness or shall have ceased to exist, no direct or
indirect payment may be made by the Company with respect to the principal of or
interest on the Exchange Debentures (other than payments made in Junior
Securities) or to acquire any of the Exchange Debentures or on account of the
redemption provisions of the Exchange Debentures; provided, however, that such
provision shall not prevent the making of any payment (which is not otherwise
prohibited by the previous paragraph) for more than 120 days after the Default
Notice shall have been given unless the Senior Indebtedness in respect of which
such event of default exists has been declared due and payable in its entirety,
in which case no such payment may be made until such acceleration has been
rescinded or annulled or such Senior Indebtedness has been paid in full.
Notwithstanding the foregoing, not more than one Default Notice may be given
with respect to Senior Indebtedness within a period of 240 consecutive days.
 
                                       55
<PAGE>
 
  The Exchange Indenture will provide that, upon any payment by or distribution
of the assets of the Company to creditors upon any dissolution, winding up,
liquidation, bankruptcy, reorganization, assignment for the benefit of
creditors, or any insolvency, receivership or similar proceeding relating to
the Company, all Senior Indebtedness must be paid in full, or such payment duly
provided for, before any payment or distribution (other than in Junior
Securities) is made on account of the principal of or interest on the Exchange
Debentures. (Section 1203)
 
  By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than other creditors of the Company and creditors of the Company
who are not holders of Senior Indebtedness or of the Exchange Debentures (or
the Company's 10 3/4% Debentures due 2004, the 9 1/4% Senior Subordinated Notes
due 2005, the 9 7/8% Debentures due 2013 and the 9 7/8% Debentures due 2023
(collectively, the "Debentures")) may recover more, ratably, than the Holders
of the Exchange Debentures.
 
  A Holder of Exchange Debentures by such holder's acceptance of the Exchange
Debentures agrees to be bound by such provisions and authorizes and expressly
directs the Trustee, on his behalf, to take such action as may be necessary or
appropriate to effectuate the subordination provided for in the Exchange
Indenture and appoints the Trustee his attorney-in-fact for such purpose.
(Section 1209)
 
  The amount of Senior Indebtedness outstanding at December 31, 1995, adjusted
to give pro forma effect to the transactions described under "Capitalization"
and the application of the net proceeds to the Company from the offering of the
Company's Series L Preferred Stock, would have been approximately $620.2
million.
 
 OPTIONAL REDEMPTION.
 
  The Exchange Debentures will be subject to redemption at any time on or after
April 1, 2003, at the option of the Company, in whole or in part, on not less
than 30 nor more than 60 days' prior notice at the following redemption prices
(expressed as percentages of the principal amount), if redeemed during the
12-month period beginning April 1 of the years indicated:

</TABLE>
 
in each case together with accrued interest to the redemption date (subject to
the right of Holders of record on relevant record dates to receive interest due
on an interest payment date). If less than all of the Exchange Debentures are
to be redeemed, the Trustee shall select the Exchange Debentures or portions
thereof to be redeemed either pro rata or by lot.
 
  In addition, up to 50% in aggregate principal amount of the Exchange
Debentures may be redeemed before April 1, 1999 at a price of 110% of the
principal amount thereof, plus accrued and unpaid interest thereon, out of the
net proceeds of a sale of Junior Stock to a Strategic Equity Investor or a
public offering of Class A Common Stock, provided that following such
redemption at least $325,000,000 principal amount of Exchange Debentures
remains outstanding.
 
  The Credit Agreement currently prohibits the Company from making optional
redemptions of the Exchange Debentures other than through the issuance of
subordinated indebtedness, preferred stock or common stock.

 CERTAIN COVENANTS OF THE COMPANY
 
  Upon issuance of the Exchange Debentures, the following covenants shall be
applicable:
 
  Limitation on Indebtedness. The Exchange Indenture provides that the Company
shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly incur, create, issue, assume, guarantee or otherwise become liable
for, contingently or otherwise, or become responsible for the payment of,
contingently or otherwise, any Indebtedness (other than Indebtedness between or
among any of the Company and Restricted Subsidiaries) unless, after giving
effect thereto, the Cash Flow Ratio shall be less than or equal to 9 to 1.
(Section 1007)
 
  At December 31, 1995, such Cash Flow Ratio was approximately 5.66 to 1.
 
  Limitation on Senior Subordinated Indebtedness. The Exchange Indenture
provides that the Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become liable for, contingently or otherwise, or become
responsible for the payment of, contingently or otherwise, any Indebtedness
which is both (i) senior in right of payment to the Exchange Debentures and
(ii) expressly subordinate in right of payment to any other Indebtedness of the
Company. For purposes of this covenant, Indebtedness is deemed to be senior in
right of payment to the Exchange Debentures if it is not subordinate in right
of payment to Senior Indebtedness at least to the same extent as the Exchange
Debentures are subordinate to Senior Indebtedness. (Section 1008)
 
  Limitation on Restricted Payments. The Exchange Indenture provides that, so
long as any of the Exchange Debentures remains outstanding, the Company will
not, and will not permit any Restricted Subsidiary to, make any Restricted
Payment if (a) at the time of such proposed Restricted Payment, a Default or
Event of Default shall have occurred and be continuing or shall occur as a
consequence of such Restricted Payment or (b) immediately after giving effect
to such Restricted Payment, the aggregate of all Restricted Payments that shall
have been made on or after July 1, 1988 would exceed the sum of:
 
    (i) $25,000,000, plus
 
    (ii) an amount equal to the difference between (A) the Cumulative Cash
  Flow Credit and (B) 1.2 multiplied by Cumulative Interest Expense.
 
  Notwithstanding the foregoing, so long as no Default or Event of Default
shall have occurred and be continuing, the Company may make any Permitted
Restricted Payment; provided, however, that such Permitted Restricted Payment
shall thereafter be counted as a Restricted Payment solely for purposes of
calculating whether any future Restricted Payments are permitted under clause
(b) of the preceding sentence.
 
  For purposes of the "Limitation on Restricted Payments" covenant, the amount
of any Restricted Payment or Permitted Restricted Payment, if other than cash,
shall be based upon fair market value as determined by the Board of Directors
of the Company, whose good faith determination shall be conclusive. (Section
1009)
 
  The foregoing provisions do not prevent: (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at such date of
declaration such payment complied with the above provisions; (ii) the
retirement or redemption of any shares of the Company's capital stock or
warrants, rights or options to acquire capital stock of the Company, in
exchange for, or out of the proceeds of a substantially concurrent sale of,
other shares of the Company's capital stock or warrants, rights or options to
acquire capital stock of the Company (other than Disqualified Stock); and (iii)
the redemption of or payments of cash dividends on the Series C Preferred Stock
outstanding on January 1, 1995, which redemptions or dividends are provided for
by the terms of the Series C Preferred Stock in effect on such date (or the
redemption of or payment of cash dividends on any security of the Company
issued in exchange for or upon the conversion of such Series C Preferred Stock;
provided that the aggregate amount payable pursuant to the terms of such
security is no greater than the aggregate amount payable pursuant to the terms
of the Series C Preferred Stock). For
 
                                       57
<PAGE>
 
purposes of determining the aggregate permissible amount of Restricted Payments
in accordance with clause (b) of the first paragraph of this covenant, all
amounts expended pursuant to clauses (i) and (iii) of this paragraph shall be
included and all amounts expended or received pursuant to clause (ii) of this
paragraph shall be excluded; provided, however, that amounts paid pursuant to
clause (i) of this paragraph shall be included only to the extent that such
amounts were not previously included in calculating Restricted Payments.
(Section 1009)
 
  For the purposes of the foregoing provisions, the net proceeds from the
issuance of shares of capital stock of the Company upon conversion of
Indebtedness shall be deemed to be an amount equal to (i) the accreted value of
such Indebtedness so converted on the date of such conversion and (ii) the
additional consideration, if any, received by the Company upon such conversion
thereof, less any cash payment on account of fractional shares (such
consideration, if in property other than cash, to be determined by the Board of
Directors of the Company, whose good faith determination shall be conclusive).
If the Company makes a Restricted Payment which, at the time of the making of
such Restricted Payment, would in the good faith determination of the Company
be permitted under the requirements of this covenant, such Restricted Payment
shall be deemed to have been made in compliance with this covenant
notwithstanding any subsequent adjustments made in good faith to the Company's
financial statements affecting Cumulative Cash Flow Credit or Cumulative
Interest Expense for any period. (Section 1009)
 
  As of December 31, 1995, this covenant would have permitted the Company to
make Restricted Payments of $597.7 million.
 
  Limitation on Investments in Unrestricted Subsidiaries and Affiliates. The
Company will not, and will not permit any Restricted Subsidiary to, directly or
indirectly (i) make any Investment or (ii) allow any Restricted Subsidiary to
become an Unrestricted Subsidiary (a "redesignation of a Restricted
Subsidiary"), in each case unless (a) no Default or Event of Default shall have
occurred and be continuing or shall occur as a consequence of such Investment
or such redesignation of a Restricted Subsidiary and (b) after giving effect
thereto, the Cash Flow Ratio shall be less than or equal to 9 to 1.
 
  The foregoing provisions of this covenant shall not prohibit (i) any renewal
or reclassification of any Investment existing on the date hereof or (ii) trade
credit extended on usual and customary terms in the ordinary course of
business. (Section 1010)
 
  Transactions with Affiliates. The Exchange Indenture provides that the
Company shall not, and shall not permit any of its subsidiaries to, sell,
lease, transfer or otherwise dispose of any of its properties or assets to or
purchase any property or assets from, or enter into any contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, an
Affiliate of the Company that is not a subsidiary of the Company, having a
value, or for consideration having a value, in excess of $10,000,000
individually or in the aggregate unless the Board of Directors of the Company
shall make a good faith determination that the terms of such transaction are,
taken as a whole, no less favorable to the Company or such subsidiary, as the
case may be, than those which might be available in a comparable transaction
with an unrelated Person. For purposes of clarification, this provision shall
not apply to Restricted Payments or Permitted Restricted Payments permitted
under "Limitation on Restricted Payments". (Section 1011)
 
 CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Company may not consolidate or merge with or into, or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
assets to, any Person, unless: (i) the entity formed by such consolidation or
merger (if other than the Company) or to which such sale, assignment, transfer,
lease, conveyance or disposition shall have been made 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 assume by a supplemental indenture all
the obligations of the Company under the Exchange Debentures and the Exchange
Indenture; (ii) immediately before and immediately after such transaction, and
after giving effect thereto, no Default or
 
                                       58
<PAGE>
 
Event of Default shall have occurred and be continuing; and (iii) immediately
after such transaction, and after giving effect thereto, the Person formed by
or surviving any such consolidation or merger, or to which such sale,
assignment, transfer, lease or conveyance or disposition shall have been made,
shall have a Cash Flow Ratio not in excess of 9 to 1. (Section 801)
 
 EVENTS OF DEFAULT
 
  The following are Events of Default under the Exchange Indenture: (1) default
for 30 days in payment of interest on the Exchange Debentures; (2) default in
payment of principal or premium, if any, on the Exchange Debentures at
Maturity, upon acceleration, redemption or otherwise; (3) failure to comply
with any other covenant or agreement of the Company, continued for 60 days (or,
with respect to certain covenants or agreements, 30 days) after written notice
as provided in the Exchange Indenture; (4) a default or defaults under any
mortgage, indenture or instrument which secures or evidences any Indebtedness
for money borrowed or guaranteed by the Company or a Restricted Subsidiary in
an aggregate amount of $10,000,000 or more (but excluding any Indebtedness for
the deferred purchase price of property or services owed to the Person
providing such property or services as to which the Company or such Restricted
Subsidiary is contesting its obligation to pay the same in good faith and by
proper proceedings and for which the Company or such Restricted Subsidiary has
established appropriate reserves) which result from the failure to pay such
Indebtedness at final maturity or which have resulted in the acceleration of
such Indebtedness; (5) the entry of a final judgment or final judgments for the
payment of money by a court or courts of competent jurisdiction against the
Company or any Restricted Subsidiary in an aggregate amount exceeding
$10,000,000 which remain undischarged and unbonded for a period (during which
execution shall not be effectively stayed) of 60 days or as to which an
enforcement proceeding has been commenced by any creditor, and (6) certain
events of bankruptcy, insolvency or reorganization. (Section 501)
 
  If an Event of Default (other than as specified in clause (6) above) shall
occur and be continuing under the Exchange Indenture, either the Trustee or the
Holders of not less than 25% in aggregate principal amount of the outstanding
Exchange Debentures, by written notice to the Company and the agents, if any,
under the Credit Agreement (and to the Trustee if such notice is given by the
Holders), may declare all the unpaid principal of, premium, if any, and
interest on the Exchange Debentures to be due and payable as provided in the
Exchange Indenture. Upon a declaration of acceleration, such principal,
premium, if any, and accrued interest shall be due and payable upon the first
to occur of an acceleration under the Credit Agreement or ten days after
receipt by the Company and the agents, if any, under the Credit Agreement of
such written notice. No action on the part of the Trustee or any Holder of the
Exchange Debentures is required for such acceleration if an Event of Default
specified in clause (6) above shall occur and be continuing. The Holders of at
least a majority in principal amount of the Exchange Debentures then
outstanding may rescind an acceleration and its consequences if (i) all
existing Events of Default, other than the nonpayment of principal of, premium,
if any, or interest on the Exchange Debentures which have become due solely
because of the acceleration, have been cured or waived and (ii) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction. A declaration of acceleration because of an Event of Default
specified in clause (4) of the preceding paragraph would be automatically
annulled if the Indebtedness referred to therein were discharged, or the
Holders thereof rescinded their declaration of acceleration referred to
therein, within 30 days after the acceleration of the Exchange Debentures and
no other Event of Default had occurred and not been cured or waived during such
period. (Section 502) The Holders of a majority in principal amount of the
Exchange Debentures outstanding also have the right to waive certain past
defaults under the Exchange Indenture. (Section 513)
 
  No Holder of any Exchange Debentures issued under the Exchange Indenture has
any right to institute any proceeding with respect to such Exchange Indenture
or for any remedy thereunder, unless (i) such Holder has previously given to
the Trustee written notice of a continuing Event of Default under the Exchange
Indenture, (ii) the Holders of at least 25% in principal amount of the
outstanding Exchange Debentures issued under the Exchange Indenture have made
written request and offered reasonable indemnity to the Trustee to institute
such proceeding as Trustee under the Exchange Indenture, and (iii) the Trustee
has not
 
                                       59
<PAGE>
 
received from the Holders of a majority in principal amount of the outstanding
Exchange Debentures a direction inconsistent with such request and the Trustee
has failed to institute such proceeding within 60 days after receipt of such
notice. (Section 507) Such limitations do not apply, however, to a suit
instituted by a Holder of an Exchange Debenture for the enforcement of payment
of the principal of or premium, if any, or interest on such Exchange Debenture
on or after the respective due dates expressed in such Exchange Debenture.
(Section 508)
 
  During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the Exchange Indenture and
use the same degree of care and skill in its exercise thereof as a prudent
person would exercise under the circumstances in the conduct of such person's
own affairs. Subject to the provisions of the Exchange Indenture relating to
the duties of the Trustee, in case an Event of Default shall occur and be
continuing, the Trustee is not under any obligation to exercise any of its
rights or powers under the Exchange Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity. (Section 602) Subject to such provisions for
the indemnification of the Trustee, the Holders of a majority in principal
amount of the outstanding Exchange Debentures have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee under
the Exchange Indenture. (Section 512)
 
  The Company is required to furnish to the Trustee an annual statement as to
the performance by the Company of its obligations under the Exchange Indenture
and as to any default in such performance. (Section 1013)
 
 DEFEASANCE
 
  The Company may at any time terminate all of its obligations with respect to
the Exchange Debentures ("defeasance"), except for certain obligations,
including those regarding the Defeasance Trust (as defined below) and
obligations to register the transfer or exchange of Exchange Debentures, to
replace mutilated, destroyed, lost or stolen Exchange Debentures and to
maintain agencies in respect of the Exchange Debentures. The Company may also
at any time terminate its obligations under the covenants set forth in the
Exchange Indenture, which are described under "--Certain Covenants of the
Company" above, and any omission to comply with such obligations shall not
constitute a Default or an Event of Default with respect to the Exchange
Debentures ("covenant defeasance"). (Sections 1402, 1403 and 1404)
 
  In order to exercise either defeasance or covenant defeasance, (i) the
Company must irrevocably deposit in trust, for the benefit of the Holders, with
the Trustee money or U.S. Government Obligations, or a combination thereof, in
such amounts as will be sufficient to pay the principal of and premium, if any,
and interest on the Exchange Debentures to redemption or maturity (the
"Defeasance Trust"), (ii) the Company must deliver opinions of counsel to the
effect that such Holders will not recognize income, gain or loss for federal
income tax purposes as a result of such defeasance or covenant defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such defeasance or
covenant defeasance had not occurred (in the case of defeasance, such opinion
must refer to and be based upon a ruling of the Internal Revenue Service or a
change in applicable federal income tax laws), (iii) no event or condition
shall exist that, pursuant to certain provisions described under
"Subordination" above, would prevent the Company from making payments of
principal of and premium, if any, and interest on the Exchange Debentures at
the date of the irrevocable deposit referred to above or at any time during the
period ending on the 91st day after such deposit date and (iv) the Company must
comply with certain other conditions. (Section 1404)
 
 SATISFACTION AND DISCHARGE OF THE EXCHANGE INDENTURE AND THE EXCHANGE
DEBENTURES
 
  The Exchange Indenture will cease to be of further effect (except as to
surviving rights of registration of transfer or exchange of Exchange
Debentures, as expressly provided for in the Exchange Indenture) when
 
                                       60
<PAGE>
 
either (i) all such Exchange Debentures theretofore authenticated and delivered
(except lost, stolen or destroyed Exchange Debentures which have been replaced
or paid) have been delivered to the Trustee for cancellation and the Company
has paid all sums payable by it under the Exchange Indenture or (ii) all such
Exchange Debentures not theretofore delivered to the Trustee for cancellation
(a) have become due and payable, or (b) will become due and payable within one
year, or (c) are to be called for redemption within one year, and the Company
has irrevocably deposited or caused to be deposited with the Trustee funds in
an amount sufficient to pay the entire indebtedness on such Exchange Debentures
not theretofore delivered to the Trustee for cancellation, for principal (and
premium, if any) and interest to the date of deposit (if such Exchange
Debentures are then due and payable) or to the applicable maturity or
redemption date (as the case may be), and the Company has paid all sums payable
by it under the Exchange Indenture. (Section 401)
 
 MODIFICATION AND WAIVER
 
  Modifications and amendments of the Exchange Indenture or the Exchange
Debentures may be made by the Company and the Trustee with the consent of the
Holders of not less than a majority in aggregate principal amount of the
outstanding Exchange Debentures; provided, however, that no such modification
or amendment may, without the consent of the Holder of each outstanding
Exchange Debenture, (i) change the Stated Maturity of the principal of, or the
premium, if any, or any installment of interest on, the Exchange Debentures,
(ii) reduce the principal amount of, or the premium, if any, or interest on,
the Exchange Debentures, (iii) change the Currency in which any Exchange
Debenture or any premium or the interest thereon is payable, (iv) impair the
right to institute suit for the enforcement of any payment on or with respect
to the Exchange Debentures, (v) reduce the percentage in principal amount of
outstanding Exchange Debentures necessary to waive compliance with certain
provisions of the Exchange Indenture or to waive certain defaults, (vi) modify
any of the provisions relating to supplemental indentures requiring the consent
of Holders or relating to the waiver of past defaults, except to increase the
percentage of outstanding Exchange Debentures required for such actions or to
provide that certain other provisions of the Exchange Indenture cannot be
modified or waived without the consent of the Holder of each Exchange Debenture
affected thereby, or (vii) modify any of the provisions of the Exchange
Indenture relating to the subordination of the Exchange Debentures in a manner
adverse to the Holders thereof. (Sections 901 and 902)
 
  The Holders of a majority in aggregate principal amount of the Exchange
Debentures then outstanding may waive compliance with certain restrictive
covenants and provisions of the Exchange Indenture. (Section 1014)
 
 REGARDING THE TRUSTEE
 
  The Bank of New York ("BONY") is the Trustee under the Exchange Indenture and
the indentures relating to the Company's 10 3/4% Debentures due 2004, the 9
7/8% Debentures due 2013, the 9 7/8% Debentures due 2023, the 9 1/4% Senior
Subordinated Notes due 2005, 11 3/4% Senior Subordinated Debentures due 2007
and 8 1/2% Convertible Subordinated Debentures due 2007. BONY is a party to
certain credit agreements with the Company and its subsidiaries, including the
Credit Agreement, borrowings under which constitute Senior Indebtedness under
the Exchange Indenture. BONY may also maintain other banking arrangements with
the Company in the ordinary course of business.

consolidated basis in accordance with generally accepted accounting principles
(except for the amortization of deferred installation income which shall

operating expenses (including technical, programming, sales, selling, general

(i) if the Company and its Subsidiaries, after the date of the Exchange
Indenture and prior to the date of an RPH Transaction, make Investments in RPH
(in cash or assets) aggregating not more than $15,000,000, then such RPH

(ii) if the Company or any Subsidiary makes any Investment in RPH, after the
date of the Exchange Indenture and prior to the date of such RPH Transaction,
that is not permitted by the foregoing clause (i), then such RPH Transaction

whose good faith determination shall be conclusive.

a restriction on the foregoing actions, while a financial covenant none of the
components of which is directly impacted by the taking of the action (e.g., the
payment of a dividend) itself (such as a debt to cash flow test) would not be

as an Unrestricted Subsidiary in accordance with the provisions of the
"Limitation on Investments in Unrestricted Subsidiaries and Affiliates"
covenant.

Preferred Stock) (with which the Exchange Debentures are intended to rank on a
parity), whether outstanding on the date of the Exchange Indenture or
thereafter created, incurred or assumed, which is (x) for money borrowed, (y)
evidenced by a note or similar instrument given in connection with the
acquisition of any businesses, properties or assets of any kind or (z) in
respect of any Capitalized Lease Obligations and (ii) all renewals, extensions,
refundings, increases or refinancings thereof, unless, in the case of (i) or
(ii) above, the instrument under which the Debt is created, incurred, assumed
or guaranteed expressly provides that such Debt is not senior in right of
payment to the Exchange Debentures. For purposes of clarification, Senior

recovered from the holder of such Senior Indebtedness under any applicable
Bankruptcy Laws or otherwise (other than by reason of some wrongful conduct on
the part of the holders of such Debt).

of any dividend, either in cash or in property (except dividends payable in
common stock or common shares of capital stock of such Person), or the making

outstanding.

United States Treasury securities (as compiled and published in the most recent

the Preferred Stock or, if such Statistical Release is no longer published, any
publicly available source of similar market data with a constant maturity most
nearly equal to the then remaining period to the date scheduled for the
mandatory redemption of the Preferred Stock; provided, however, that if such
period is not equal to the constant maturity of a United States Treasury
security for which a weekly average yield is given, the Treasury Rate shall be
obtained by linear interpolation (calculated to the nearest one-twelfth of a
year) from the weekly average yields of United States Treasury securities for
which such yields are given.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a summary of the material anticipated federal income tax
consequences of an exchange of the Old Depositary Shares for New Depositary
Shares. This summary is based upon the provisions of the Internal Revenue Code
of 1986, as amended (the "Code"), the final, temporary and proposed regulations
promulgated thereunder, and administrative rulings and judicial decisions now
in effect, all of which are subject to change (possibly with retroactive
effect) or different interpretations. This summary does not purport to deal
with all aspects of federal income taxation that may be relevant to an
investor's decision to hold the New Depositary Shares and it is not intended to
be applicable to all categories of investors, some of which, such as dealers in
securities, banks, insurance companies, tax-exempt organizations, foreign
persons, persons that hold New Depositary Shares or Exchange Debentures as part
of a straddle or conversion transaction or holders subject to the alternative
minimum tax, may be subject to special rules. In addition, the summary is
limited to persons that will hold the New Depositary Shares and any Exchange
Debentures received in exchange therefor as "capital assets" (generally,
property held for investment) within the meaning of Section 1221 of the Code.
Holders should note that Counsel's opinion is not binding on the Service and
there can be no assurance that the Internal Revenue Service (the "Service")
will take a similar view with respect to the tax consequences described below.
No ruling has been or will be requested by the Company from the Service on any
tax matters relating to the New Depositary Shares or Exchange Debentures. ALL
PROSPECTIVE HOLDERS OF SHARES OF NEW DEPOSITARY SHARES ARE ADVISED TO CONSULT
THEIR OWN TAX ADVISORS REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF NEW DEPOSITARY SHARES OR
EXCHANGE DEBENTURES.
 
   In general, for U.S. federal income tax purposes, holders of New Depositary
Shares will be treated as the owners of the shares of Series M Preferred Stock
represented by those New Depositary Shares.
 
                                       66
<PAGE>
 
 TAXATION OF HOLDERS ON EXCHANGE
 
  No gain or loss will be recognized by a holder that exchanges Old Depositary
Shares for New Depositary Shares pursuant to the Exchange Offer. The basis of
New Depositary Shares received by such holder in the exchange will be the same
as the Old Depositary Shares exchanged therefor. The holder's holding period
for such New Depositary Shares will include the holder's holding period for the
Old Depositary Shares so exchanged, provided that the Old Depositary Shares
were held as a capital asset.
 
                              PLAN OF DISTRIBUTION
 
  Each broker-dealer that receives New Depositary Shares for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Depositary Shares. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Depositary Shares received
in exchange for Old Depositary Shares where such Old Depositary Shares were
acquired as a result of market-making activities or other trading activities.
The Company has agreed that it will make this Prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
such resale for a period of 90 days from the date of this Prospectus, or such
shorter period as will terminate when all Old Depositary Shares acquired by
broker-dealers for their own accounts as a result of market-making activities
or other trading activities have been exchanged for New Depositary Shares and
resold by such broker-dealers.
 
  The Company will not receive any proceeds from any sale of New Depositary
Shares by broker-dealers. New Depositary Shares received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the New Depositary Shares or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such New
Depositary Shares. Any broker-dealer that resells New Depositary Shares 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 New Depositary
Shares may be deemed to be a "underwriter" within the meaning of the Securities
Act and any profit on any such resale of New Depositary Shares and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The Letter of Transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
  For a period of 90 days from the date of this Prospectus, or such shorter
period as will terminate when all Old Depositary Shares acquired by broker-
dealers for their own accounts as a result of market-making activities or other
trading activities have been exchanged for New Depositary Shares and resold by
such broker-dealers, the Company will promptly send additional copies of this
Prospectus and any amendment or supplement to this Prospectus to any broker-
dealer that requests such documents in the Letter of Transmittal. The Company
has agreed to indemnify such broker-dealers against certain liabilities,
including liabilities under the Securities Act.
 
                     VALIDITY OF THE NEW DEPOSITARY SHARES
 
  The validity of the New Depositary Shares will be passed upon for the Company
by Sullivan & Cromwell, New York, New York.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers as well as other employees and
individuals against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement in connection with specified actions, suits or
proceedings, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation--a "derivative action"),
if they acted in good faith and in a manner they reasonably believed to be in
or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe their
conduct was unlawful. A similar standard is applicable in the case of
derivative actions, except that indemnification only extends to expenses
(including attorneys' fees) incurred in connection with defense or settlement
of such action, and the statute requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation. The statute provides that it is not exclusive of other
rights to which those seeking indemnification may be entitled under any by-law,
agreement, vote of stockholders or disinterested directors or otherwise.
 
  The first paragraph of Article Ninth of the Corporation's Certificate of
Incorporation provides:
 
      The corporation shall, to the fullest extent permitted by Section 145
    of the General Corporation Law of the State of Delaware, as the same
    may be amended and supplemented, or by any successor thereto, indemnify
    any and all persons whom it shall have power to indemnify under said
    section from and against any and all of the expenses, liabilities or
    other matters referred to in or covered by said section. Such right to
    indemnification shall continue as to a person who has ceased to be a
    director, officer, employee or agent and shall inure to the benefit of
    the heirs, executors and administrators of such a person. The
    indemnification provided for herein shall not be deemed exclusive of
    any other rights to which those seeking indemnification may be entitled
    under any By-Law, agreement, vote of stockholders or disinterested
    directors or otherwise.
 
  Article VIII of the By-Laws of the Corporation provides:
 
      A. The corporation shall indemnify each person who was or is made a
    party or is threatened to be made a party to or is involved in any
    threatened, pending or completed action, suit or proceeding, whether
    civil, criminal, administrative or investigative (hereinafter a
    "proceeding"), by reason of the fact that he or she, or a person of
    whom he or she is the legal representative, is or was a director or
    officer of the corporation or is or was serving at the request of the
    corporation as a director, officer, employee or agent of another
    corporation or of a partnership, joint venture, trust or other
    enterprise, including service with respect to employee benefit plans,
    whether the basis of such proceeding is alleged action in an official
    capacity as a director, officer, employee or agent or alleged action in
    any other capacity while serving as a director, officer, employee or
    agent, to the maximum extent authorized by the Delaware General
    Corporation Law, as the same exists or may hereafter be amended (but,
    in the case of any such amendment, only to the extent that such
    amendment permits the corporation to provide broader indemnification
    rights than said law permitted the corporation to provide prior to such
    amendment), against all expense, liability and loss (including
    attorney's fees, judgments, fines, ERISA excise taxes or penalties and
    amounts paid or to be paid in settlement) reasonably incurred by such
    person in connection with such proceeding. Such indemnification shall
    continue as to a person who has ceased to be a director, officer,
    employee or agent and shall inure to the benefit of his or her heirs,
    executors and administrators. The right to indemnification conferred in
    this Article shall be a contract right and shall include the right to
    be paid by the corporation the expenses incurred in defending any such
    proceeding in advance of its final disposition; provided that, if the
    Delaware General Corporation Law so requires, the payment of such
    expenses incurred by a director or officer in advance of the final
    disposition of a proceeding
 
                                      II-1
<PAGE>
 
    shall be made only upon receipt by the corporation of an undertaking by
    or on behalf of such person to repay all amounts so advanced if it
    shall ultimately be determined that such person is not entitled to be
    indemnified by the corporation as authorized in this Article or
    otherwise.
 
      B. The right to indemnification and advancement of expenses conferred
    on any person by this Article shall not limit the corporation from
    providing any other indemnification permitted by law nor shall it be
    deemed exclusive of any other right which any such person may have or
    hereafter acquire under any statute, provision of the Certificate of
    Incorporation, by-law, agreement, vote of stockholders or disinterested
    directors or otherwise.
 
      C. The corporation may purchase and maintain insurance, at its
    expense, to protect itself and any director, officer, employee or agent
    of the corporation or another corporation, partnership, joint venture,
    or other enterprise against any expense, liability or loss, whether or
    not the corporation would have the power to indemnify such person
    against such expense, liability or loss under the Delaware General
    Corporation Law.
 
  The Corporation has entered into indemnification agreements with certain of
its officers and directors indemnifying such officers and directors from and
against certain expenses, liabilities or other matters referred to in or
covered by Section 145 of the Delaware General Corporation Law. The Corporation
has also entered into an agreement with Charles F. Dolan ("Mr. Dolan"), the
Chairman of the Corporation, pursuant to which Mr. Dolan has agreed to
guarantee the Corporation's obligation to indemnify its officers and directors
to the fullest extent permitted by Delaware law. In addition, subject to
certain limitations, Mr. Dolan has agreed to indemnify such officers and
directors against any loss or expense such person may incur in connection with
any transaction involving Mr. Dolan or entities affiliated with Mr. Dolan to
the extent indemnification is not provided by the Corporation. Any payment
required to be made by Mr. Dolan pursuant to such agreement will be reduced by
any proceeds of insurance or reimbursement under any other form of
indemnification reimbursement available to such officer or director. The
Corporation maintains directors' and officers' liability insurance.
 
  Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) for payments of unlawful dividends or unlawful stock repurchases or
redemptions, or (iv) for any transaction from which the director derived an
improper personal benefit. The second paragraph of Article Ninth of the
Corporation's Certificate of Incorporation provides for such limitation of
liability.

ITEM 22. UNDERTAKINGS.
 
  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) that is incorporated by reference in the registration statement 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
registrant, pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act of 1933 and is, therefore,
 
                                      II-3
<PAGE>
 
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by any such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether or not such indemnification 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 registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in
the registration statement when it became effective.
 
  The undersigned registrant hereby undertakes 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 this registration statement in reliance upon Rule 430A and
    contained in a form of prospectus filed by the registrant pursuant to
    Rule 424(b)(1) or (4) or 497(h) under the Securities Act 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.
